ITEM 1. BUSINESS

OVERVIEW

Aflac Incorporated (the Parent Company) was incorporated in 1973 under the laws of the state of Georgia. The Parent Company and its subsidiaries (collectively, the Company) provide financial protection to millions of policyholders and customers in Japan and the United States (U.S.). The Company’s principal business is supplemental health and life insurance products with the goal to provide customers the best value in supplemental insurance products in Japan and the U.S. When a policyholder or insured gets sick or hurt, the Company pays cash benefits fairly and promptly for eligible claims. Throughout its 70-year history, the Company’s supplemental insurance policies have given policyholders the opportunity to focus on recovery, not financial stress.

The Company is authorized to conduct insurance business in all 50 states, the District of Columbia, several U.S. territories, and Japan. The Company’s website is: www.aflac.com. Information included on the Company’s website is not incorporated by reference into this filing. The Company makes available free of charge through its website, its annual report on Form 10-K, its quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports as soon as reasonably practicable after they have been electronically filed with or furnished to the SEC.

REVENUE-GENERATING ACTIVITIES

The Company's strategy for growth in Japan and the U.S. has remained straightforward and consistent for many years. The Company develops relevant supplemental health insurance products offering financial protection from the rising out-of-pocket expenses associated with medical events that are not covered by the insureds' primary coverage. The Company also offers a complement of other voluntary and employer-paid health and life insurance products to fit the needs of its customers. Additionally, the Company aims to obtain more customers by selling where the customer prefers to purchase protection, whether through an agent or broker, a distribution partner or directly from the Company. To help promote its insurance products, the Company’s marketing campaigns feature the Aflac Duck.

LONG-TERM GROWTH STRATEGY

Item 1 Graphic.jpg

In 1999, the Company had been running commercials for nearly a decade, but its brand awareness was hovering at about 10%. An innovative marketing campaign with something unique and memorable that would build brand awareness was needed. The Aflac Duck’s first commercial in the U.S., “Park Bench,” aired on January 1, 2000 and taught consumers how to pronounce “Aflac.” The Aflac Duck made its international debut in Japan in 2003. In the time since its U.S. debut, the Aflac Duck has become one of the most familiar advertising icons in the world, appearing in many commercials and countless print ads in both the U.S. and Japan. Celebrating its 25th anniversary in the U.S., the Aflac Duck continues to be a helpmate who increases brand knowledge and connection.

The Company's insurance business consists of two reporting segments: Aflac Japan and Aflac U.S. The primary insurance subsidiary in the Aflac Japan segment is Aflac Life Insurance Japan Ltd. (ALIJ). Aflac U.S. includes the insurance subsidiaries American Family Life Assurance Company of Columbus (Aflac); Continental American Insurance Company (CAIC), branded as Aflac Group Insurance (AGI); American Family Life Assurance Company of New York (Aflac New York); Tier One Insurance Company (TOIC); and Aflac Benefits Solutions, Inc. (ABS), which provides a platform for Aflac Dental and Vision in the U.S.

For information on the Company's results of operations and financial information by segment, see Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) and Note 2 of the Notes to the Consolidated Financial Statements.

AFLAC JAPAN

Aflac Japan is the principal contributor to the Parent Company's consolidated earnings and the largest insurer in Japan in terms of cancer and medical (third sector insurance products) policies in force. For information on Aflac Japan's operating results, see the Aflac Japan Segment section of Item 7. MD&A.

Insurance Products

Aflac Japan's third sector insurance products are supplemental products designed to help consumers pay for medical and nonmedical costs that are not reimbursed under Japan's national health insurance system. Changes in Japan's economy and an aging population have put increasing pressure on Japan's national health care system. As a result, more costs have been shifted to Japanese consumers, who in turn have become increasingly interested in insurance products that help them manage those costs. Aflac Japan has responded to this consumer need by enhancing existing products and developing new products. Aflac Japan remains focused on maintaining leadership in third sector insurance products that are less interest rate sensitive and have strong and stable margins. At the same time, Aflac Japan complements this core business with similarly profitable first sector products as outlined below.

Third Sector Insurance Products

Cancer

Cancer Insurance Aflac Japan pioneered the cancer insurance market in Japan in 1974, and remains the number one provider of cancer insurance in Japan today. Aflac Japan's cancer insurance products provide a lump-sum benefit upon initial diagnosis of cancer and fixed daily benefits for subsequent hospitalization and outpatient treatments due to cancer, as well as cancer-related surgical and convalescent care benefits. In March 2025, Aflac Japan launched a new cancer insurance product, Miraito, a service-integrated product designed to allow customers the flexibility to choose necessary coverage to meet their individual needs. Aflac Japan continues to provide Yori-sou Cancer Consultation Support, a service that provides comprehensive support from the moment a policyholder suspects cancer through treatment and recovery. This service is provided to all existing policyholders of Aflac Japan cancer insurance products, including Miraito.

Medical and Other Health

Medical Insurance Aflac Japan's medical insurance products provide benefits for hospitalization, surgeries and outpatient treatment of various illnesses, as well as lump sum benefits related to three critical illnesses: cancer, heart attack, and stroke. In December 2025, Aflac Japan launched a new medical insurance product, Anshin Palette, which offers customers the flexibility to choose only the coverage they need from a wide range of options.

Other

Nursing Care Insurance Aflac Japan's Nursing Care Insurance provides coverage for out-of-pocket costs incurred when receiving public nursing care services.

First Sector Insurance Products

Life

Protection-Type Life Insurance

Whole Life Prepare Smart Whole-Life Insurance is a whole life insurance product with low cash surrender value, which offers non-smoking policyholders further discounted premiums, and it provides beneficiaries, typically a designated family member, with a pre-determined benefit payment upon the death of the insured.

GIFT GIFT is a term life insurance product that provides beneficiaries, typically family members, with a fixed amount of money every month upon a breadwinner’s death or serious disability as family support.

Savings-Type Life Insurance

Tsumitasu Launched in June 2024, Tsumitasu is an insurance product designed primarily for post-retirement preparation, with asset formation features and coverage for nursing care and other benefits.

WAYS and Child Endowment WAYS is an insurance product which has features that allow policyholders to convert a portion of their life insurance to medical, nursing care or fixed annuity benefits at a predetermined age. Aflac Japan's child endowment insurance product offers a death benefit until a child reaches age 18. This product also pays a lump-sum benefit at the time of the child's entry into high school, as well as an educational annuity for each of the four years during his or her college education.

Distribution Channels

Traditional Sales Channel This distribution channel includes individual agencies, independent corporate agencies and affiliated corporate agencies. Aflac Japan was represented by approximately 6,300 sales agencies at the end of 2025, with approximately 112,000 licensed sales associates employed by those agencies, including individual agencies.

Dai-ichi Life Aflac Japan's alliance with Dai-ichi Life was launched in 2001, and approximately 37,000 Dai-ichi Life representatives offer Aflac Japan's cancer products. Dai-ichi Life is included in Aflac Japan's affiliated corporate agencies distribution channel.

Japan Post Group Aflac Japan's alliance with Japan Post Group, which is included in Aflac Japan's affiliated corporate agencies distribution channel, was launched in 2008. After the alliance strengthened in 2013, the number of postal outlets of Japan Post Co. Ltd. (Japan Post Co.) offering Aflac Japan's cancer product increased, with approximately 20,000 postal outlets as of December 31, 2025. Japan Post Insurance Co., Ltd. (Japan Post Insurance) offers Aflac Japan's cancer products through its 76 branches responsible for corporate sales and 626 service departments in charge of individual sales.

Daido Life Aflac Japan's alliance with Daido Life was launched in 2013, and approximately 3,700 Daido Life representatives offer Aflac Japan's cancer products to mainly small and medium-sized business owners, executives and employees. Daido Life is included in Aflac Japan's affiliated corporate agencies distribution channel.

Banks Consumers in Japan rely on banks to provide not only traditional bank services, but also as one key source to provide insurance solutions and other services. At December 31, 2025, Aflac Japan had agreements with approximately 90% of the total number of banks in Japan to sell its products.

Competitive Markets

The Company competes with other insurance carriers through product design, price, policyholder service, and sales efforts. Since the deregulation of the Japan market in 2001, the number of insurance companies offering stand-alone cancer and medical insurance has increased, intensifying competition. However, based on Aflac Japan's size of annualized premiums in force and diversified distribution network, the Company believes it is well-positioned to continue to adapt to increased competition. Furthermore, the Company believes the continued development and maintenance of operating efficiencies will allow Aflac Japan to offer affordable products that appeal to consumers. The Company believes Aflac Japan will remain a leading provider of third sector products such as cancer and medical insurance coverage in Japan, principally due to its experience in the market, well-known brand, low-cost operations, expansive marketing system and product expertise.

Government Regulation

Financial Services Agency (FSA) The financial and business affairs of Aflac Japan are subject to examination by Japan's FSA. Aflac Japan files annual and interim reports and financial statements for the Japanese insurance operations based on a March 31 fiscal year-end, prepared in accordance with Japanese regulatory accounting practices prescribed or permitted by the FSA. Japanese regulatory basis earnings are determined using accounting principles that differ materially from U.S. generally accepted accounting principles (U.S. GAAP). For additional information, see Note 14 of the Notes to the Consolidated Financial Statements.

Two FSA regulations applicable to Aflac Japan are outlined below.

▪Privacy and Cybersecurity

With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the Act on the Protection of Personal Information (APPI) and guidelines issued by FSA and other governmental authorities.

•FSA Solvency Standard

The FSA maintains a solvency standard, the solvency margin ratio (SMR), which is used by Japanese regulators to monitor the financial strength of insurance companies. Aflac Japan's SMR is sensitive to interest rate, credit spread and foreign exchange rate changes. See the Liquidity and Capital Resources section of Item 7. MD&A for additional information on SMR, including a discussion of measures the Company has taken to mitigate the sensitivity of Aflac Japan's SMR and the introduction of an economic value-based solvency regime based on the Insurance Capital Standards (ICS) for insurance companies effective for Aflac Japan's 2025 fiscal year-end.

Companies Act of Japan Aflac Japan dividend distributions to the Parent Company are subject to permitted dividend capacity under the Companies Act of Japan.

Policyholder Protection The Japanese insurance industry has a policyholder protection corporation that provides funds for the policyholders of insolvent insurers. For additional information, see the Policyholder Protection section of Item 7. MD&A.

For additional information regarding Aflac Japan's operations and regulations, see the Aflac Japan Segment subsection of Item 7. MD&A and Notes 2 and 14 of the Notes to the Consolidated Financial Statements.

AFLAC U.S.

The Company designs its U.S. insurance products to provide supplemental coverage for people who already have major medical or primary insurance coverage, as Aflac U.S. insurance policies pay benefits regardless of other insurance. Aflac U.S. products are distributed in the individual and group supplemental insurance markets. Aflac's individual policies are portable, meaning that individuals may retain their full insurance coverage upon separation from employment or affiliation with a group, generally at the same premium. Individual policies are typically guaranteed-renewable for the lifetime of the policyholder (to age 75 for short-term disability policies).

Insurance Products

Accident

Accident Insurance Aflac U.S. offers accident coverage on both an individual and group basis. These policies pay cash benefits in the event of a covered injury. The accident portion of the policy includes lump-sum benefits for accidental death, dismemberment and specific injuries as well as fixed benefits for hospital confinement. Additional benefits are also available for home modifications, wellness and increased benefits for injuries related to participation in an organized sporting activity.



5


Disability

Disability Insurance Aflac U.S. offers short-term disability benefits on both an individual and group basis and long-term disability benefits on a group basis. These plans provide coverage for covered injury, illness or mental health conditions.

Critical Care

Cancer Insurance Aflac U.S.'s cancer insurance products provide a lump-sum benefit upon initial diagnosis of cancer and subsequent benefits for treatment received due to cancer. Aflac U.S. offers cancer insurance on an individual basis.

Critical Illness Insurance Aflac U.S. offers coverage for critical illness plans on both an individual and group basis. These policies are designed to pay cash benefits in the event of critical illnesses such as heart attack, stroke or cancer.

Hospital Indemnity

Hospital Indemnity Insurance Aflac U.S. offers hospital indemnity coverage on both an individual and group basis. Hospital indemnity products provide policyholders fixed dollar benefits triggered by hospitalization due to accident or sickness. Indemnity benefits for inpatient and outpatient surgeries, as well as various other diagnostic events, are also available. Aflac U.S. also offers a lump sum rider for a range of critical illness events that can be added to its individual accident, short-term disability and hospital indemnity products.

Dental and Vision

Dental and Vision Insurance Aflac U.S. offers network dental and vision products on a group basis, as well as fixed-benefit dental coverage on an individual basis.

Life

Life Insurance Aflac U.S. offers term- and whole-life policies on both an individual and group basis.

Seasonality

In recent years, new annualized premium sales are generally higher in the fourth quarter for Aflac U.S. group business due to the timing of open enrollment for many employers. As a result, a significant portion of total new annualized premium sales for Aflac U.S. group business are generated in the fourth quarter, which typically results in over one third of Aflac U.S. total sales being generated in the fourth quarter.

Distribution Channels

Independent Associates/Career Agents The career agent channel in Aflac U.S. focuses on marketing Aflac to the small business market, defined as employers of between three and 99 employees. Sales associates in the U.S. are independent contractors and are paid commissions and other variable compensation based on first-year and renewal premiums from their sales of insurance products.

Brokers The broker channel of Aflac U.S. focuses on selling to the mid- and large-case market, which is comprised of employers with 100 or more employees and typically an average size of 1,000 employees or more. Brokers in the U.S. are independent contractors and are paid commissions and other variable compensation based on first-year and renewal premiums from their sales of insurance products.

In 2025, the Aflac U.S. sales force included an average of approximately 5,300 U.S. agents, including brokers, who were actively producing business on a weekly basis. For additional information, see the Aflac U.S. Segment subsection of Item 7. MD&A.

Consumer Markets While Aflac U.S. primarily markets its insurance products at the worksite, Aflac U.S. is also expanding its distribution strategy to directly reach consumers outside of the traditional worksite through digital lead generation.



6


Competitive Markets

Aflac U.S. competes against several supplemental insurance carriers on a national and regional basis. Aflac U.S. believes its policies, premium rates, platforms, value-added services and sales commissions are competitive by product type. Moreover, Aflac U.S. believes that its products are distinct from competitive offerings given its product focus (including features, benefits and claims service model), distribution capabilities and brand awareness. 

Since Aflac products provide an additional level of financial protection for policyholders, the Company believes the increased financial exposure some employees may face creates a favorable opportunity for Aflac U.S. products. However, given the profitability erosion some major medical carriers are facing in their core lines of business, the Company has seen a more competitive landscape as these carriers seek entry into Aflac's supplemental product segments and leverage their core benefit offerings by bundling and discounting products in order to gain market share.

Government Regulation

State Insurance Regulation The Parent Company and its U.S. insurance subsidiaries, Aflac, CAIC, TOIC (Nebraska-domiciled insurance companies), Aflac New York (a New York-domiciled insurance company) and ABS (a licensed third-party administrator in most U.S. jurisdictions and a pre-paid limited health service organization in Florida) are subject to state regulations in the U.S. as an insurance holding company system. Such regulations generally provide that certain transactions between companies within the holding company system must be fair and equitable. In addition, transfers of assets among such affiliated companies, certain dividend payments from insurance subsidiaries and certain transactions between companies within the system, including management fees, loans and advances are subject to prior notice to, or approval by, state regulatory authorities. These laws generally require, among other things, the insurance holding company and each insurance company directly owned by the holding company to register with the insurance departments of their respective domiciliary states and to furnish annually financial and other information about the operations of companies within the holding company system.

Like all U.S. insurance companies, Aflac, CAIC, TOIC and Aflac New York are subject to regulation and supervision in the jurisdictions in which they do business. In general, the insurance laws of the various jurisdictions establish supervisory agencies with broad administrative powers relating to, among other things:

•granting and revoking licenses to transact business
•regulating trade and claims practices
•licensing of insurance agents and brokers
•approval of policy forms and premium rates
•standards of solvency and maintenance of specified policy benefit reserves and minimum loss ratio requirements
•capital requirements
•limitations on dividends to shareholders
•the nature of and limitations on investments
•deposits of securities for the benefit of policyholders
•filing of financial statements prepared in accordance with statutory insurance accounting practices prescribed or permitted by regulatory authorities
•periodic examinations of the market conduct, financial, and other affairs of insurance companies

The insurance laws of Nebraska that govern the Company's activities provide that the acquisition or change of “control” of a domestic insurer or of any person that controls a domestic insurer cannot be consummated without the prior approval of the Nebraska Department of Insurance (NDOI). A person seeking to acquire control, directly or indirectly, of a domestic insurance company or of any person controlling a domestic insurance company (in the case of Aflac, CAIC and TOIC, the Parent Company) must generally file with the NDOI an application for change of control containing certain information required by statute and published regulations and provide a copy to the Company. In Nebraska, control is generally presumed to exist if any person, directly or indirectly, acquires 10% or more of an insurance company or of any other person or entity controlling the insurance company. The 10% presumption is not conclusive and control may be found to exist at less than 10%. Similar laws apply in New York, the domiciliary jurisdiction of Aflac's New York insurance subsidiary.

State insurance departments conduct periodic examinations of the books and records, financial reporting, policy filings and market conduct of insurance companies domiciled in their states, generally once every three to five years. Examinations are generally carried out in cooperation with the insurance departments of other states under guidelines promulgated by the National Association of Insurance Commissioners (NAIC). Beginning in 2024 and concluding in 2025, the NDOI and the New York State Department of Financial Services (NYSDFS) conducted full-scope, risk-focused


7


financial examinations on their respective state domiciled insurance entities covering the reporting period January 1, 2020 – December 31, 2023. Additionally, beginning in 2023 and concluding in 2025, the NYSDFS conducted a routine market conduct examination on Aflac New York covering the five-year period ended on December 31, 2022. There were no material findings in any of the NDOI and NYSDFS final examination reports.

NAIC Risk-Based Capital The NAIC continually reviews regulatory matters, such as risk-based capital (RBC) modernization, group capital calculations and liquidity risk assessment. The NAIC uses an RBC formula relating to insurance risk, business risk, asset risk and interest rate risk to facilitate identification by insurance regulators of inadequately capitalized insurance companies based upon the types and mix of risk inherent in the insurer's operations. The formulas for determining the amount of RBC specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of a company's regulatory total adjusted capital to its authorized control level RBC as defined by the NAIC. Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. The levels are company action, regulatory action, authorized control, and mandatory control. See Note 14 of the Notes to the Consolidated Financial Statements and the Liquidity and Capital Resources section of Item 7. MD&A for additional information on RBC.

Guaranty Association and Similar Arrangements Under state insurance guaranty association laws and similar laws in international jurisdictions, the Company is subject to assessments, based on the share of business the Company writes in the relevant jurisdiction, for certain obligations of insolvent insurance companies to policyholders and claimants. In the U.S., some states permit member insurers to recover assessments paid through full or partial premium tax offsets. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction.

Federal and State Regulation Federal and state legislation and regulations in several areas, including health care reform legislation, financial services reform legislation, securities regulation, pension regulation, privacy, anti-money laundering, tort reform legislation and taxation, can significantly and adversely affect insurance companies. Certain federal and state laws and regulations applicable to Aflac U.S. are outlined below.

•Patient Protection and Affordable Care Act

The Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (collectively, the ACA), federal health care reform legislation, gave the U.S. federal government direct regulatory authority over the business of health insurance. The ACA, as enacted, does not require material changes in the design of the Company's insurance products. However, indirect consequences of, or changes to, the legislation and regulations could present challenges that could potentially have an impact on the Company's sales model, financial condition and results of operations. Certain provisions of the ACA have been and may continue to be subject to challenge through litigation, the ultimate effects of which on the ACA are uncertain. See Item 1A. Risk Factors for the risk factor entitled, "Extensive regulation and changes in legislation can impact profitability and growth" for additional information.

•Dodd-Frank Act

Title VII of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank) and regulations issued thereunder, in particular rules to require central clearing for certain types of derivatives, may have an impact on the Company's derivative activity, including activity on behalf of Aflac Japan. The Dodd-Frank Act also established a Federal Insurance Office (FIO) under the U.S. Department of the Treasury to monitor all aspects of the insurance industry and of lines of business other than certain health insurance, certain long-term care insurance and crop insurance.

•Privacy and Cybersecurity

In the absence of a comprehensive federal privacy law, states are making a push towards privacy legislation. Personally identifiable information is used in support of many of the Company's business processes. For many years, the standard for protection and treatment of that data was benchmarked by privacy and security provisions of the federal Gramm-Leach-Bliley Act of 1999 (GLBA) and in the Health Insurance Portability and Accountability Act of 1996 (HIPAA). As consumers have grown more concerned about the protection of their data, as well as how their data is used by organizations, jurisdictions within and outside of the U.S. have created legislation and issued regulations that apply or may in the future apply to aspects of Aflac U.S. operations and allow consumers the right to access, correct, delete, or opt out of the sale or share, or limit the use of their data. Although not all apply to Aflac U.S. operations, an example of these state privacy laws is the California Consumer Privacy Act.

Businesses across industries have also seen an increase in lawsuits alleging tracking technologies on their websites violate state or federal wiretapping laws. At the federal level, the Telephone Consumer Protection Act (TCPA) continues to provide plaintiffs with a private right of action for claims alleging violation of the TCPA. Additionally, certain states are adopting the NAIC Model Bulletin on the Use of Artificial Intelligence Systems by Insurers and, in limited cases, passing their own laws related to artificial intelligence.

Cybersecurity continues to be an area of evolving focus for legislation and regulatory activity. The NYSDFS Cybersecurity Requirements for Financial Services Companies applies to Aflac New York. This regulation requires, among other things, risk assessments, administrative and technical controls, incident reporting procedures, business continuity plans, and certain cybersecurity governance, such as the designation of a Chief Information Security Officer and senior governing body oversight.

ITEM 1A. RISK FACTORS

The Company faces a wide range of risks, and its continued success depends on its ability to identify, prioritize, and appropriately manage enterprise risk exposures. Readers should carefully consider each of the following risks and all of the other information set forth in this Form 10-K. These risks and other factors may affect forward-looking statements, including those in this document or made by the Company elsewhere, such as in earnings release webcasts, investor conference presentations or press releases. The risks and uncertainties described herein may not be the only ones facing the Company. Additional risks and uncertainties not presently known to the Company or that the Company currently believes to be immaterial may also adversely affect its business. If any of the following risks and uncertainties develops into actual events, there could be a material impact on the Company's business, results of operations, financial condition and liquidity.

Investment and Markets Risk Factors

Difficult conditions in global capital markets and the economy could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business.

The Company's results of operations are materially affected by conditions in the global capital markets and the global economy generally, including in its two primary operating markets of the U.S. and Japan. Inflation globally remains elevated but continues to trend downwards after monetary tightening, recovery of supply chains, and phasing out of extraordinary fiscal support. In the U.S. and other regions, inflation rates reduced to a level that supported monetary loosening by central banks, but the risk of a return to increasing inflation remains alongside risks of weakening economic conditions. The Bank of Japan remains an exception to the major central bank loosening trends, ending a prolonged period of negative interest rates on bank reserves in March 2024. Continuing geopolitical tensions, including armed conflicts and regime changes, exacerbate uncertainty and can contribute to volatility across both physical and financial asset classes. Economic uncertainty is also impacted by potential policy changes in the U.S., including proposed domestic regulations focused on consumer pricing, trade tariffs and increasing trade restrictions driven by security concerns and broader geopolitical tensions. Continuing higher interest rates and softer economic conditions could impact the creditworthiness and value of the Company's existing investment portfolio, influence opportunities for new investments and have a negative impact on the Company's results of operations and financial positions.

The Company's investments are vulnerable to adverse market developments such as asset price volatility, lack of market liquidity, credit rating downgrades, payment defaults, asset restructurings, increased losses, and other risks. The Company has evaluated its holdings and identified investments in areas such as commercial real estate and highly leveraged companies as the most exposed to continued high interest rates and an economic downturn. These investments are experiencing and may continue to experience higher credit losses, credit rating downgrades and/or defaults and a deterioration in the value of collateral in the case of secured investments. The Company has examined in each case whether a reduction in size of the holdings is appropriate. The Company has identified assets impacted or expected to be impacted by continued high interest rates and economic contraction, but other investments not identified to date may also be impacted. The availability of new investments in certain private market asset classes has been and may continue to be limited. The Company may need to adjust its investment strategy and/or be forced to liquidate investments to pay claims. The continuing difference between U.S. dollar and Japanese yen interest rates also contributes to costs of hedging foreign currency exchange risk of U.S. dollar-denominated investments held by Aflac Japan. The Company is not able to predict the ultimate impact of inflation, interest rate changes, interest rate differences and other changing market conditions on the Company’s investments and hedging programs. See the risk factor below entitled, “The Company is exposed to significant interest rate risk, which may adversely affect its results of operations, financial condition and liquidity” for additional information. See the Investments and Results of Operations by Segment sections of Item 7. MD&A, for additional information.

As the Company holds a significant amount of fixed maturity securities issued by borrowers located in many different parts of the world, its financial results are directly influenced by global financial markets. Potential weakness in global capital markets could adversely affect the Company's financial condition, including its capital position and overall profitability. Market volatility and recessionary pressures could result in significant realized or unrealized losses due to severe price declines driven by high interest rates or increases in credit spreads, defaults in payment of principal or interest, or credit rating downgrades.

Japan is the largest market for the Company's insurance products, and the Company owns substantial holdings in Japan Government Bonds (JGBs). Government actions to stimulate the economy affect the value of the Company's existing holdings, its reinvestment rate on new investments in JGBs or other Japanese yen-denominated assets, and consumer behavior relative to the Company's suite of insurance products. The additional government debt from fiscal stimulus


13
actions could adversely impact the Japan sovereign credit profile, which could in turn lead to volatility in Japanese capital and currency markets. The Bank of Japan ended its policy of negative interest rates in March 2024, and uncertainty about future Japan interest rate changes and the impact of increased rates on the Japanese economy could also contribute to volatility in Japanese markets.

Should investors become concerned with any of the Company's investment holdings, including the concentration in JGBs, its access to market sources of funding could be negatively impacted. It is possible that lenders or debt investors may also become concerned if the Company incurs large investment losses or if the level of the Company's business activity decreases due to a market downturn or there are further adverse economic trends in the U.S. or Japan, specifically, or generally in developed markets.

The Company needs liquidity to pay its operating expenses, dividends on its common stock, interest on its debt, and liabilities. See the Liquidity and Capital Resources section of Item 7. MD&A, for additional information. In the event the Company's current resources do not meet its needs, the Company may need to seek additional financing. The Company's access to additional financing will depend on a variety of factors such as market conditions, the general availability of credit within the financial services industry and its credit rating. See the risk factor below entitled, “Any decrease in the Company's financial strength or debt ratings may have an adverse effect on its competitive position and access to liquidity and capital” for additional information.

Broad economic factors such as consumer spending, business investment, government spending, the volatility and strength of the capital markets and inflation, as well as ongoing central bank responses to these factors, all affect the business and economic environment and, indirectly, the amount and profitability of the Company's business. In an economic downturn characterized by higher unemployment, lower family income, lower corporate earnings, lower business investment and lower consumer spending, the demand for financial and insurance products could be adversely affected. This adverse effect could be particularly significant for companies such as Aflac that distribute supplemental, discretionary insurance products primarily through the worksite in the event that economic conditions result in a decrease in the number of new hires and total employees. Adverse changes in the economy could potentially lead the Company's customers to be less inclined to purchase supplemental insurance coverage or to decide to cancel or modify existing insurance coverage. Further, Aflac U.S. may experience higher rates of policy lapses during periods of increased job turnover and workforce mobility within the U.S. economy. The above factors could adversely affect the Company's net earned premiums, results of operations and financial condition. The Company is unable to predict the course of the global financial markets or the recurrence, duration or severity of disruptions in such markets.

Defaults, downgrades, widening credit spreads or other events impairing the value of the fixed maturity securities and loan receivables in the Company's investment portfolio may reduce the Company's earnings and capital position.

The Company is subject to the risk that the issuers and/or guarantors of fixed maturity securities and loan receivables the Company owns may default on principal or interest. A significant portion of the Company's portfolio represents an unsecured obligation of the issuer, including some that may be subordinated to other debt in the issuer’s capital structure. In these cases, many factors can influence the overall creditworthiness of the issuer and ultimately its ability to service and repay the Company's holdings. This can include changes in the global economy, the issuer's assets, strategy, or management, shifts in the dynamics of the industries in which the issuer competes, the issuer's access to additional funding, government trade policies and the overall health of the credit markets. Factors unique to the Company's securities including contractual protections such as financial covenants or relative position in the issuer's capital structure also influence the value of the Company's holdings. In addition, for investments representing secured obligations of an issuer, such as mortgage loan receivables, the underlying value of the collateral may not be sufficient to fully recover the amount of principal and interest owed to the Company if a default occurs.

Most of the Company's investments carry a rating by one or more of the Nationally Recognized Statistical Rating Organizations (NRSROs or rating agencies). Any change in the rating agencies' approach to evaluating credit and assigning an opinion could negatively impact the fair value of the Company's portfolio. Any expected or sustained credit deterioration of the Company's investments will negatively impact the Company's net income and capital position through credit impairment and other credit related losses. Credit related losses that are not temporary in nature would also affect the Company's solvency ratios in the U.S., Japan and Bermuda. Aflac Japan has certain regulatory accounting requirements for realizing impairments that could be triggered by credit-related losses, which may be different from U.S. GAAP and statutory requirements. These impairment losses could negatively impact Aflac Japan's earnings, and the corresponding dividends and capital deployment. The Company is also subject to the risk that any collateral providing credit enhancement to the Company's investments could deteriorate.



14
The Company is also exposed to the general movement in credit market spreads. A widening of credit spreads could reduce the value of the Company's existing portfolio, create unrealized losses on its investment portfolio, and reduce the Company's adjusted capital position and/or the dividend capacity of the Company's insurance subsidiaries. A tightening of credit spreads could reduce the net investment income available to the Company on new credit investments. Increased market volatility also makes it difficult to value certain of the Company's investment holdings. For additional information, see the Critical Accounting Estimates section of Item 7. MD&A, and the Credit Risk subsection of Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

The Company is exposed to significant interest rate risk, which may adversely affect its results of operations, financial condition and liquidity.

The Company has substantial investment portfolios that support its policy liabilities. Interest rate risk is an inherent portfolio, business and capital risk for the Company, and significant changes in interest rates could have a material adverse effect on the Company's consolidated results of operations, financial condition or cash flows through realized losses, impairments, changes in unrealized positions, and liquidity. Changes in interest rates could also result in the Company having to recognize gains or losses because the Company disposes of some or all of its investments prior to their maturity.

The Company's exposure to interest rate risk relates primarily to the ability to invest future cash flows to support the interest rate assumption made at the time of the establishment of the Company's product pricing and reserving. Low levels of interest rates on investments experienced in Japan and the U.S. over the last decade have also reduced the level of investment income earned by the Company. In spite of recent decreases in interest rates in the U.S. and other regions and interest rate increases in Japan, interest rates in Japan remain lower than in the U.S., and the Company's overall level of investment income will continue to be negatively impacted from Japan’s low interest rates from investments made in prior periods at lower rates and from decreasing rates in the U.S. While the Company generally seeks to maintain a diversified portfolio of fixed-income investments that reflects the cash flow and duration characteristics of the liabilities it supports, the Company may not be able to fully mitigate the interest rate risk of its assets relative to its liabilities. Prolonged periods of low interest rates also heighten the risk associated with future increases in interest rates because an increasing proportion of the Company's investment portfolio include investments that bear lower rates of return than the embedded book yield of the investment portfolio. The Company’s current interest rate hedging programs are primarily focused on addressing risks of floating rate investments and are not designed to fully protect against the impact of interest rate changes on the Company. In addition, uncertainty regarding the timing, pace and magnitude of future interest rate changes could further increase fluctuations in the value of the Company’s assets and liabilities and adversely affect its capital position and liquidity.

A sustained decline in interest rates could hinder the Company's ability to earn the returns assumed in the pricing and the reserving for its insurance products at the time of sale and issue and may also influence the Company's ability to develop and price attractive new products and could impact its overall sales levels. The Company's first sector products are more interest rate sensitive than third sector products. While the Bank of Japan ended its negative interest rate policy in March of 2024, low interest rates in Japan could continue to have a negative impact on the distribution and pricing of these products. Additionally, a decrease in interest rates increases the fair value of the Company’s fixed maturity investments, which could result in increases to the Company’s overall equity. However, the decrease in interest rates increases the liability for future policy benefits (LFPB), which could result in reductions to the Company’s overall equity.

Conversely and concurrently, a rise in interest rates would improve the Company's ability to earn higher rates of return on future investments, as well as floating rate investments held in its investment portfolio. A rise in interest rates also decreases the LFPB, which could result in increases to the Company's overall equity. However, rising interest rates negatively impact the fair values of the Company's fixed maturity investments which could result in reductions to the Company's overall equity. Portfolio management considerations, the availability of investments, as well as declines in fair value may constrain the ability of the Company to transition its investments to higher rate securities. Significant increases in interest rates could cause declines in the values of the Company's investment portfolio which have a secondary impact on the Company's overall evaluation of its deferred tax asset position. An increase in the differential of short-term U.S. and Japan interest rates would also increase the cost of hedging a portion of the U.S. dollar-denominated assets held by Aflac Japan into Japanese yen, which could have a material adverse effect on the Company's business, results of operations or financial condition. Further, some of the insurance products that Aflac sells in the U.S. and Japan provide cash surrender values, and a rise in interest rates could trigger significant policy surrenders, which might require the Company to sell investment assets and recognize unrealized losses. Rising interest rates also negatively impact capital ratios in certain jurisdictions because unrealized losses on the available-for-sale investment portfolio factor into the ratio. In addition to the unrealized losses negatively impacting capital ratios, significant unrealized losses could impact the amount of dividends that could be paid under local regulations, including in Japan. For Aflac Japan, rising interest rates and widening credit


15
spreads, which reduce the fair value of Aflac Japan’s fixed-maturity investments, when combined with a strengthening Japanese yen, and the resulting decrease in the Japanese yen value of Aflac Japan’s U.S. dollar-denominated fixed-maturity investments, have a negative impact on Aflac Japan's regulatory capital. For regulatory accounting purposes for Aflac Japan, there are also certain requirements for realizing impairments that could be triggered by rising interest rates, negatively impacting Aflac Japan's regulatory earnings and corresponding dividends and capital deployment.

See the Interest Rate Risk subsection of Item 7A. Quantitative and Qualitative Disclosures about Market Risk for additional information.

The Company's concentration of business in Japan poses risks to its operations and financial condition.

Aflac Japan's adjusted revenues accounted for 53% of the Company's total adjusted revenues in 2025, compared with 55% in 2024 and 60% in 2023. The percentage of the Company's total assets attributable to Aflac Japan was 76% at December 31, 2025, compared with 77% at December 31, 2024. See Note 2 of the Notes to the Consolidated Financial Statements for additional information.

Any potential deterioration in Japan's credit quality or access to markets, the overall economy of Japan, or an increase in Japanese market volatility could adversely impact Aflac Japan's operations and its financial condition and thereby Aflac's overall financial performance. Further, because of the concentration of the Company's business in Japan and its need for long-dated Japanese yen-denominated assets, the Company has a substantial concentration of JGBs in its investment portfolio exposing the Company to credit deterioration and potential downgrades of JGBs. See the risk factor entitled “Any decrease in the Company's financial strength or debt ratings may have an adverse effect on its competitive position and access to liquidity and capital” for additional information.

The Company seeks to match investment currency and interest rate risk to its Japanese yen liabilities. The low interest rates on Japanese yen-denominated securities has a negative effect on overall net investment income. A large portion of the cash available for reinvestment each year is deployed in Japanese yen-denominated instruments and subject to the low level of Japanese yen interest rates.

Lack of availability of acceptable Japanese yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity.

The Company aims to match both the duration and currency of its assets with its liabilities. This is very difficult for Aflac Japan and Aflac Re due to the lack of available long-dated Japanese yen-denominated fixed income instruments beyond JGBs.

Aflac Japan’s investment strategy includes U.S. dollar-denominated investments. This program includes public investment-grade bonds as well as U.S. dollar-denominated investment-grade commercial mortgage loans, middle market loans, infrastructure debt, collateralized loan obligations and other loan types, high yield bond and public and private equities. The Company plans to continue adding other instruments denominated in U.S. dollars, including floating rate investments, to improve the portfolio diversification and/or return profile. Some of the U.S. dollar-denominated asset classes that the Company has added, and anticipates continuing to add, have less liquidity than investment-grade corporate bonds and in periods of market stress, certain of these U.S. dollar-denominated asset classes may experience significantly reduced liquidity, increased valuation uncertainty or wider bid-ask spreads. Aflac Re's investment strategy also includes U.S. dollar-denominated investments that are presently comprised exclusively of investment-grade bonds.

Investing in U.S. dollar-denominated investments in Aflac Japan and Aflac Re creates an unmatched foreign currency exposure and related capital ratio volatility, as both Aflac Japan and Aflac Re insurance liabilities are Japanese yen-denominated. Although the Company engages in certain foreign exchange hedging activities to partially mitigate this risk, and such hedged assets may be used to satisfy Japanese yen-denominated insurance liabilities and other business obligations, important risks remain.

In recent years, the Company has reduced the proportion of U.S. dollar-denominated investments that are subject to a currency hedge, and this proportion continues to be subject to change at the Company’s discretion. The Company has increased U.S. dollar risk exposure as the comprehensive hedging program may not always correlate to the underlying U.S. dollar-denominated assets, thereby increasing earnings volatility. These risks can significantly impact the Company's consolidated results of operations, financial position or liquidity.

Further, foreign currency derivatives used for hedging are periodically settled, which results in cash receipt or payment at inception, maturity or early termination. Cumulative net cash settlements on derivatives hedging currency exposure of


16
Aflac Japan's U.S. dollar-denominated investments are associated with existing U.S. dollar-denominated investments that continue to be hedged, previously hedged investments that continue to be held but are no longer hedged, and investments previously hedged that have since been sold, matured or redeemed and may or may not have not been converted to Japanese yen. The Company’s foreign exchange derivatives are typically shorter-dated than the underlying U.S. dollar-denominated investments being hedged, which creates roll-over risks within the hedging program that could increase the cost of such derivatives. If the Company reduces the notional amount of foreign exchange derivatives prior to the maturity of the hedged U.S. dollar-denominated investments, the foreign exchange gains or losses on the U.S. dollar-denominated investments remain economically unrealized. These foreign currency gains or losses on the investments are only economically realized, or monetized, through sale, maturity or redemption of the investments and concurrent conversion to Japanese yen. However, the Company may not realize the benefit of offsetting adverse cash settlements on hedging derivatives with cash receipts on the U.S. dollar-denominated investments if the foreign exchange rates move in an adverse direction before the investments are converted to Japanese yen, or if the investments are never converted to Japanese yen. As an example of the latter, if the Company’s actual insurance risk experience in Japan is as expected or more favorable than expected, the need for Japanese yen to pay expenses and claims would correspondingly remain at or below expected levels, thereby diminishing operational requirements to convert U.S. dollar-denominated investments to Japanese yen. The settlement of the foreign currency derivatives is included in settlement of derivatives, net in the investing activities section of the Company’s consolidated statements of cash flows.

See the risk factor entitled “The Company is exposed to foreign currency fluctuations in the Japanese yen/U.S. dollar (yen/dollar) exchange rate”, the Hedging Activities subsection of Item 7. MD&A, and the Currency Risk subsection of Item 7A. Quantitative and Qualitative Disclosures about Market Risk for additional information.

The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate.

Due to the size of Aflac Japan, where functional currency is the Japanese yen, fluctuations in the foreign exchange rate between the Japanese yen and the U.S. dollar have had, and may continue to have, a significant effect on the Company's reported financial position and results of operations. Aflac Japan's premiums and a significant portion of its investment income are received in Japanese yen, and its claims and almost all expenses are paid in Japanese yen. In accordance with U.S. GAAP, the Company translates its Japanese yen-denominated financial statement accounts into U.S. dollars for financial reporting purposes with the resulting foreign currency translation adjustments included in equity. Japanese yen weakening has the effect of suppressing current year results in relation to the prior year, including the resulting negative impact on equity. Japanese yen strengthening has the effect of magnifying current year results in relation to the prior year, including the resulting positive impact on equity.

Also in accordance with U.S. GAAP, U.S. dollar denominated assets and liabilities held by Aflac Japan are remeasured to Japanese yen and Japanese yen-denominated assets and liabilities held by Aflac Re are remeasured to U.S. dollar with the resulting foreign currency remeasurement for certain of these assets and liabilities included in earnings. Consequently, fluctuations in the yen/dollar exchange rate have resulted and could continue to result in significant earnings volatility. Japanese yen weakening in relation to the U.S. dollar increases the Japanese yen value on U.S. dollar denominated asset, while Japanese yen strengthening decreases the Japanese yen value of the U.S. dollar denominated assets.

In addition, differences between interest rates in Japan and the U.S. can lead to weakening of the Japanese yen relative to the U.S. dollar and could suppress the Company's reported financial position and results of operations relative to the comparable prior period.

For regulatory accounting purposes, there are certain requirements for realizing impairments that could be triggered by changes in the yen/dollar exchange rate and could negatively impact Aflac Japan's earnings and the corresponding dividends and capital deployment.

The Company engages in certain foreign currency hedging activities to hedge the exposure to Japanese yen from its net investment in Japanese operations. Aflac Japan purchases Japanese yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to Japanese yen, to support Japanese yen-denominated policy liabilities. However, an increase in the difference between short-term U.S. and Japan interest rates would increase the cost of hedging a portion of the U.S. dollar-denominated assets held by Aflac Japan into Japanese yen, which could have a material adverse effect on the Company's business, results of operations or financial condition. As indicated in MD&A, the Company has determined that the unhedged U.S. dollar-denominated investment portfolio acts as a natural economic currency hedge of a portion of the Company’s investment in Aflac Japan against erosion of economic value. At the same time, the unhedged U.S. dollar-denominated investment portfolio creates an unmatched foreign currency exposure and subjects Aflac Japan to volatility in regulatory capital and earnings, which may adversely impact Aflac Japan’s ability to


17
pay dividends to the Parent Company. The Company has historically maintained and currently maintains the size of the unhedged portfolio at levels below the economic equity surplus in Aflac Japan, but this strategy may not be successful.

Additionally, the Parent Company utilizes forward contracts as part of its Enterprise Corporate Hedging Program to protect the economic value of Aflac Japan in U.S. dollar terms by hedging foreign currency exchange risk related to dividend payments by Aflac Japan. The Company is exposed to currency risk when Japanese yen cash flows are converted into U.S. dollars, resulting in changes in the Company's U.S. dollar-denominated cash flows and earnings when foreign currency exchange gains or losses, respectively, are realized. This primarily occurs when Aflac Japan pays dividends in Japanese yen to the Parent Company, but it also has an impact when cash in the form of Japanese yen is converted to U.S. dollars for investment into U.S. dollar-denominated assets. The foreign exchange rates prevailing at the time of dividend payment may differ from the foreign exchange rates prevailing at the time the Japanese yen profits were earned. If the markets experience a significant strengthening of Japanese yen, this could cause cash strain at the Parent Company as a result of cash collateral and potentially cash settlement requirements. Based on the timing and severity of foreign exchange rate fluctuations combined with the level of outstanding activity in this program, the cash strain at the Parent Company could be significant.

These hedging activities are limited in scope and the strategies may not be successful.

For additional information regarding unhedged U.S. dollar-denominated securities, see the risk factor above entitled, “Lack of availability of acceptable Japanese yen-denominated investments could adversely affect the Company’s results of operations, financial position or liquidity”. See the Currency Risk subsection of Item 7A. Quantitative and Qualitative Disclosures about Market Risk for additional information.

The valuation of the Company's investments and derivatives includes methodologies, estimations and assumptions that are subject to differing interpretations and could result in changes to investment valuations that may adversely affect the Company's results of operations or financial condition.

The Company reports a significant amount of its fixed maturity securities and other investments at fair value. As such, valuations may include inputs and assumptions that are less observable or require greater estimation and valuation methods that are more sophisticated, thereby resulting in values that may be greater or less than the value at which the investments may be ultimately sold. Volatility in interest rates and foreign exchange markets, including changes in yield curves and discount rates, may increase the sensitivity of the Company's investment and derivative valuations to changes in market assumptions. Rapidly changing and unprecedented credit and equity market conditions could materially impact the valuation of securities as reported within the Company's consolidated financial statements and the period-to-period changes in fair value could vary significantly.

Valuations of the Company's derivatives fluctuate with changes in underlying market variables, such as interest rates and foreign exchange rates. During periods of market turbulence created by political instability, economic uncertainty, government interventions or other factors, the Company may experience significant changes in the volatility of its derivative valuations. Extreme market conditions can also affect the liquidity of such instruments creating marked differences in transaction levels and counterparty valuations. Depending on the severity and direction of the movements in its derivative valuations, the Company will face increases in the amount of collateral required to be posted with its counterparties. Liquidity stresses to the Company may also occur if the required collateral amounts increase significantly over a very short period of time. Conversely, the Company may be exposed to an increase in counterparty credit risk for short periods of time while calling collateral from its counterparties.

See the Critical Accounting Estimates section of Item 7. MD&A, and Notes 1, 3, 4, and 5 of the Notes to the Consolidated Financial Statements for additional information.

The determination of the amount of expected credit losses recorded on the Company's investments is based on significant valuation judgments and could materially impact its results of operations or financial position.

The Company estimates an allowance for credit losses on investments measured at amortized cost including held-to-maturity securities, loan receivables and loan commitments. For collateral dependent financial assets, including loans where foreclosure is probable, the allowance for credit losses is based on the fair value of the underlying collateral. For the Company’s available-for-sale securities, the Company evaluates an estimate for credit losses only when the fair value of the available-for-sale security is below its amortized cost basis.

The Company’s approach to estimating an allowance for credit losses is complex and incorporates significant judgments. In addition to a security, an asset class, or issuer-specific credit fundamentals, it considers relevant historical information


18
(e.g. loss statistics), current market conditions and reasonable and supportable micro and macroeconomic forecasts. The Company's management updates its expected credit loss assumptions regularly as conditions change and as new information becomes available and reflects expected credit losses in the Company's earnings when considered necessary. Furthermore, additional credit losses may need to be taken in the future. Historical trends may not be indicative of future expectations of credit losses. See Note 3 of the Notes to the Consolidated Financial Statements for additional information.

The Company cannot provide assurance that these evaluations will be accurate and effective. If the Company’s estimates of credit losses are not accurate and actual credit losses are higher than the Company’s estimates, the Company’s net income and capital position will be negatively impacted. These higher losses would also negatively affect the Company's solvency ratios in the U.S., Japan and Bermuda.

For regulatory accounting purposes for Aflac Japan, there are certain requirements for realizing impairments that could be triggered by rising interest rates, credit-related losses, or changes in foreign exchange rates, negatively impacting Aflac Japan's earnings and corresponding dividend and capital deployment.

Any decrease in the Company's financial strength or debt ratings may have an adverse effect on its competitive position and access to liquidity and capital.

NRSROs may change their ratings or outlook on an insurer's ratings due to a variety of factors including but not limited to competitive position; profitability; cash generation and other sources of liquidity; capital levels; quality of the investment portfolio; and perception of management capabilities. The ratings assigned to the Company by the NRSROs are important factors in the Company's ability to access liquidity and capital from the bank market, debt capital markets or other available sources, such as reinsurance transactions. Downgrades of the Company's credit ratings could give its derivative counterparties the right to require early termination of derivatives transactions or delivery of additional collateral, thereby adversely affecting the Company's liquidity.

Downgrades of the Company's ratings could also have a material adverse effect on agent recruiting and retention, sales, competitiveness and the marketability of its products, all of which could negatively impact the Company's liquidity, operating results and financial condition. Additionally, sales through the bank channel in Japan could be adversely affected as a result of their reliance on and sensitivity to ratings levels.

The Company cannot predict what actions rating agencies may take, or what actions the Company may take in response to the actions of rating agencies. As with other companies in the financial services industry, the Company's ratings could be downgraded at any time and without any notice by any NRSRO.

A decline in the creditworthiness of other financial institutions could adversely affect the Company.

The Company has exposure to and routinely executes transactions with counterparties in the financial services industry, including broker dealers, derivative counterparties, commercial banks and other institutions. The Company uses derivative instruments to mitigate various risks associated with its investment portfolio, notes payable, and subsidiary dividends. The Company's use of derivatives results in financial exposure to derivative counterparties. If the Company's counterparties fail or refuse to honor their obligations under derivative instruments, the Company's hedges of the risks will be ineffective, and the Company's financial condition and results of operations could be adversely affected.

The Company engages in derivative transactions directly with affiliates and unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annexes (CSAs), which generally provide for two-way collateral postings at the first dollar of exposure. In addition, a significant portion of the derivative transactions have provisions that give the counterparty the right to terminate the transaction upon a downgrade of Aflac’s financial strength rating. The actual amount of payments that the Company could be required to make depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade. If the Company is required to post collateral to support derivative contracts and/or pay cash to settle the contracts at maturity, the Company's liquidity could be strained. In addition, the Company's cleared swaps result in counterparty exposure to clearing brokers and central clearinghouses; while this exposure is mitigated in part by clearinghouse and clearing broker capital and regulation, no assurance can be provided that these counterparties will fulfill their obligations. The Company also has exposure to counterparties to securities lending transactions in the event they fail to return loaned securities. The Company is also exposed to the risk that there may be a decline in value of securities posted as collateral for securities lending programs or a decline in value of investments made with cash posted as collateral for such programs.



19
Further, the Company has agreements with various Japanese financial institutions for the distribution of its insurance products. For example, at December 31, 2025, the Company had agreements with 358 banks to market Aflac's products in Japan. Sales through these banks represented 3.3% of Aflac Japan's new annualized premium sales in 2025. Any material adverse effect on these or other financial institutions could also have an adverse effect on the Company's sales.

Aflac Japan has entered into reinsurance transactions with Aflac Re, which has less capital than external counterparties with which the Company has conducted reinsurance transactions in the past. Negative events or developments affecting any one of these counterparties could have an adverse effect on the Company's financial position or results of operations.

All of these risks related to exposure to other financial institutions could adversely impact the Company's consolidated results of operations and financial condition.

Operational-Related Risk Factors

Sales of the Company's products and services are dependent on its ability to attract, retain and support a network of qualified sales associates, brokers and employees in the U.S. and sales associates and other distribution partners in Japan.

The Company's sales, results of operations and financial condition could be materially adversely affected if its sales networks deteriorate or if the Company does not adequately provide support, training and education for its existing network of sales associates, brokers, other distribution partners and employees. In the U.S., competition exists for sales associates and brokers with demonstrated ability. Further, low rates of unemployment, such as those currently reflected in the U.S. employment market, tend to make it more difficult for Aflac U.S. to maintain its network of sales associates. In Japan, the Company's sales results are dependent upon its relationship with sales associates and other distribution partners, such as Japan Post Group, which in recent periods has accounted for a significant portion of Aflac Japan's total sales.

The Company competes with other insurers and financial institutions primarily on the basis of its products, compensation, support services and financial rating. The Company's sales associates, brokers and other distribution partners are independent contractors and may sell products of its competitors. If the Company's competitors offer products that are more attractive, or pay more competitive commissions than the Company does, any or all of these distribution partners may concentrate their efforts on selling the Company's competitors' products instead of the Company's. In addition to the Company's commissioned sales force in the U.S., Aflac has expanded its sales leadership team to include a salaried sales force of over 200 market directors and broker sales professionals. The Company's inability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, could have a material adverse effect on the Company's sales, results of operations and financial condition.

Additionally, as the Japan and U.S. employment markets continue to evolve, there is risk that the Company's practices regarding attracting, developing, and retaining employees may not be fully effective. Employees may leave the Company or choose other employers over the Company due to various factors, including a competitive labor market. Although Aflac U.S. has not experienced any material labor shortage to date, it has experienced elevated levels of workforce turnover and there has been an overall tightening of, and increased competition within, the U.S. labor market. These conditions, together with higher levels of inflation may result in increased operating expenses. A sustained labor shortage or continuing elevated turnover rates within the Aflac U.S. workforce, due to labor market factors or the state of the U.S. economy, could lead to increased costs of the day-to-day operation of the Aflac U.S. business, the inability to hire and retain employees, or the outsourcing of certain operations. Failure to successfully meet and maintain sufficient levels of employees may diminish the Company's ability to achieve its financial and compliance objectives, both of which are time consuming and personnel-intensive.

If future policy benefits, claims or expenses exceed those anticipated in establishing premiums and reserves, the Company's financial results would be adversely affected.

The assumptions and estimates that the Company uses in establishing premiums and reserves depend on the Company's judgment regarding the likelihood of future events and are inherently uncertain. Many factors can cause actual outcomes to deviate from these assumptions and estimates, such as changes in incidence rates, economic conditions, changes in government healthcare policy, advances in medical technology, changes in treatment patterns, and changes in average lifespan. Accordingly, the Company cannot determine with precision the ultimate amounts that it will pay for, or the timing of payment of, actual benefits and claims or whether the assets supporting the policy liabilities will grow to the level the Company assumes prior to payment of benefits or claims. If the Company's actual experience is different from its assumptions or estimates, the Company's premiums and reserves may prove inadequate. Reserve assumptions are


20
regularly reviewed by the Company and may be revised if future expectations change. These experience deviations and assumption updates could have a material adverse effect on the Company's business, results of operations and financial condition.

The success of the Company's business depends in part on effective information technology systems, on continuing to develop and implement improvements in technology, and on successful execution of revenue growth and expense management initiatives.

The Company's business depends in large part on its technology systems for interacting with employers, policyholders, sales associates, and brokers, and the Company's business strategy involves providing customers with easy-to-use products to meet their needs and ensuring employees have the technology in place to support those needs. Some of the Company's information technology systems and software are older, legacy-type systems that are less efficient and require an ongoing commitment of significant resources to maintain or upgrade to current standards including adequate business continuity procedures. As such, the Company is investing in technology and other capabilities to continuously enhance its customer experience, while also seeking to increase efficiencies. The Company is also developing new and innovative products and enhancing existing products. The Company will continue to incur expenses related to, among other things, investments in digital capabilities and product innovation including the development and use of artificial intelligence (AI). The Company’s development of new technology, including the use of AI by the Company and third-party vendors, could lead to an increased risk of a business interruption or a cybersecurity breach. Further, the Company’s long-term strategy depends on successful operational execution and its ability to execute on its transformational initiatives, including investments in technology and other initiatives intended to grow revenue and control expenses, combined with its ability to achieve efficiencies and attract and retain personnel. If the Company does not maintain the effectiveness of its systems and continue to develop and enhance information systems that support its business processes in a cost-efficient manner, the Company's sales, business retention, operations and reputation could be adversely affected and it could be exposed to litigation, regulatory proceedings and fines or penalties.

Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality, integrity or privacy of sensitive data residing on such systems, could harm the Company's business.

The Company stores confidential policyholder, employee, agent, broker, and other proprietary information on its information technology systems. The Company also depends heavily on its telecommunication, information technology and other operational systems and on the integrity and timeliness of data it uses to run its businesses and service its customers. The Company’s information technology and other systems, as well as those of third-party providers and participants in the Company’s distribution channels, have been and will likely continue to be subject to physical or electronic break-ins, unauthorized tampering, security breaches, social engineering, phishing, web application attacks, computer viruses or other malicious codes, or other cyber-related attacks, that may result in the failure to adequately maintain the security, confidentiality, integrity, or privacy of sensitive data, including personal information relating to customers and prospective customers, or in the misappropriation of the Company's intellectual property or proprietary information. The risk of a cybersecurity incident impacting business operations has grown as third parties continue to develop new and highly sophisticated methods of attack. The rapid evolution and increased adoption of artificial intelligence technologies may also heighten the Company's cybersecurity risks by making cyber-attacks more difficult to detect, contain, and mitigate.

The Company and its third-parties or vendors have and may continue to experience outages or cyber-related attacks that disrupt the operations or impact the confidentiality, availability or integrity of information, which may result in operational, legal, regulatory or financial harm. Furthermore, depending upon the type of attack, it could impact the confidentiality, integrity and/or availability of IT systems and data, disrupting business operations and resulting in the loss of consumer confidence. Although the Company attempts to manage its exposure to such events through the purchase of cyber liability insurance, such events are inherently unpredictable, and insurance may not be sufficient to protect the Company against all losses. As a result, events such as these, including the June 2025 cyber incident where the Company became aware of the exfiltration of certain personal information relating to a substantial number of customers, beneficiaries, employees, agents, and other individuals in the Company’s U.S. business, could adversely affect the Company's financial condition or results of operations due to incurred costs and remediation. Although data leakage issues the Company has experienced, as of the date of this report, have not been determined to have a reasonably likely material impact on the Company's financial condition or results of operations, the Company's security systems or processes may not prevent or mitigate future break-ins, tampering, security breaches or other cyber-related attacks. As the Company pursues IT transformation and increased cloud adoption, it inherently exposes the Company to potential cyber-related attacks.



21
Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality or privacy of sensitive data residing on such systems, whether due to actions by the Company or others, including third-party providers and participants in the company’s distribution channels, could delay or disrupt the Company's ability to do business and service its customers, seriously harm the Company's brand, reputation, and ability to compete effectively, subject it to regulatory sanctions and other claims, lead to a loss of customers and revenues and otherwise adversely affect the Company's business. In addition, the costs to address or remediate system interruptions or security threats and vulnerabilities, whether before or after an incident, could be significant.

The Company could also be subject to legal risk, including government enforcement action and civil litigation, related to cyber-attacks and security breaches, which could adversely affect the Company’s business, reputation, financial condition or results of operations. In addition, the Company may be adversely impacted by reputational harm or a loss of confidence in the security and integrity of its information technology systems among customers, beneficiaries, employees, agents, and others.

As a holding company, the Parent Company depends on the ability of its subsidiaries to transfer funds to it to meet its debt service and other obligations and to pay dividends on its common stock.

The Parent Company is a holding company and has no direct operations, and its most significant assets are the stock of its subsidiaries. Because the Parent Company conducts its operations through its operating subsidiaries, the Parent Company depends on those entities for dividends and other payments to generate the funds necessary to meet its debt service and other obligations, to pay dividends on and conduct repurchases of its common stock, and to make investments into its subsidiaries or external opportunities.

Aflac is domiciled in Nebraska and is subject to insurance regulations that impose certain limitations and restrictions on payments of dividends, management fees, loans and advances by Aflac to the Parent Company. The Nebraska insurance statutes require prior approval for dividend distributions that exceed the greater of the net income from operations, which excludes net realized investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. The Nebraska insurance department also must approve service arrangements and other transactions within the affiliated group of companies. The FSA does not allow dividends or other payments from Aflac Japan unless it meets certain financial criteria as governed by Japanese corporate law. Under these criteria, dividend capacity at the Japan subsidiary is defined as total equity excluding common stock and capital reserves but reduced for net after-tax unrealized losses on available-for-sale securities.

The ability of Aflac and Aflac Japan to pay dividends or make other payments to the Parent Company could also be constrained by the Company's dependency on financial strength ratings from independent rating agencies. Any inability of the Company's subsidiaries to pay dividends or make other payments to the Parent Company could have a material adverse effect on the Company's financial condition and results of operations.

For the foregoing reasons, there is no assurance that the earnings from, or other available assets of, the Parent Company's operating subsidiaries will be sufficient to make distributions to enable the Company to operate.

The Company's risk management policies and procedures may prove to be ineffective and leave the Company exposed to unidentified or unanticipated risk, which could adversely affect the Company's businesses or result in losses.

The Company has developed an enterprise-wide risk management and governance framework to mitigate risk and loss to the Company. The Company maintains policies, procedures and controls intended to identify, measure, monitor, report and analyze the risks to which the Company is exposed. However, there are inherent limitations to risk management strategies because risk may exist, or emerge in the future, that the Company has not appropriately anticipated or identified. If the Company's risk management framework proves ineffective, the Company may suffer unexpected losses and could be materially adversely affected. As the Company's businesses change and the markets in which it operates evolve, the Company's risk management framework may not evolve at the same pace as those changes, and risks may not be appropriately identified, monitored or managed. In times of market stress, unanticipated market movements or unanticipated claims experience resulting from greater than expected morbidity, mortality, longevity, or persistency, the effectiveness of the Company's risk management strategies may be limited, resulting in losses to the Company. Under difficult or less liquid market conditions, the Company's risk management strategies may be ineffective or more difficult or expensive to execute because other market participants may be using the same or similar strategies to manage risk.

Many of the Company's risk management strategies or techniques are based upon historical customer and market behavior and all such strategies and techniques are based to some degree on management’s subjective judgment. The


22
Company cannot provide assurance that its risk management framework, including the underlying assumptions or strategies, will be accurate and effective.

Management of operational, legal and regulatory risks requires, among other things, policies, procedures and controls to record properly and verify a large number of transactions and events, and these policies, procedures and controls may not be fully effective. The Company's businesses and corporate areas primarily use models to project future cash flows associated with pricing products, calculating reserves and valuing assets, and evaluating risk and determining capital requirements, among other uses. These models are utilized under a risk management policy approved by the Company's executive risk management committees, however, the models may not operate properly and rely on assumptions and projections that are inherently uncertain. As the Company's businesses continue to grow and evolve, the number and complexity of models the Company utilizes expands, increasing the Company's exposure to error in the design, implementation or use of models, including the associated input data and assumptions.

Past or future misconduct by the Company's employees or employees of third parties (suppliers which are cost-based relationships and alliance partners which are revenue-generating relationships) could result in violations of law by the Company, regulatory sanctions and/or serious reputational or financial harm, and the precautions the Company takes to prevent and detect this activity may not be effective in all cases. Despite the Company's published Supplier Code of Conduct, due diligence of the Company's alliance partners, and rigorous contracting procedures (including financial, legal, IT security, AI and risk reviews), there can be no assurance that controls and procedures that the Company employs will be effective. Additionally, the use of third parties also poses operational risks that could result in financial loss, operational disruption, brand damage, or compliance issues. Inadequate oversight of the Company's third-party suppliers due to the lack of policies, procedures, training and governance may lead to financial loss or damage to the Aflac brand.

The use of third-party vendors to support the Company's operations makes the Company susceptible to the operational risk of those third parties, which could lower revenues, increase costs, reduce profits, disrupt business, or damage the Company’s reputation.

The Company utilizes third-party vendors to provide certain business support services and functions, which exposes the Company to risks outside the control of the Company that may lead to business disruptions. The reliance on these third-party vendors creates a number of business risks, such as the risk that the Company may not maintain service quality, control or effective management of the outsourced business operations and that the Company cannot control the information systems, facilities or networks of such third-party vendors. Additionally, the Company is at risk of being unable to meet legal, regulatory, financial or customer obligations if the information systems, facilities or networks of a third-party vendor are disrupted, damaged or fail, whether due to physical disruptions, such as fire, natural disaster, pandemic or power outage, or due to cybersecurity incidents, ransomware or other impacts to vendors, including labor strikes, political unrest and terrorist attacks. Since certain third-party vendors conduct operations for the Company outside the U.S., the political and military events in foreign jurisdictions could have an adverse impact on the Company’s outsourced operations. The Company may be adversely affected by a third-party vendor who operates in a poorly controlled manner or fails to deliver contracted services, which could lower revenues, increase costs, reduce profits, disrupt business, or damage the Company’s reputation.

Regulatory Risk Factors

Tax rates applicable to the Company may change.

The Company is subject to taxation in Japan, and in the U.S. under federal and numerous state and local tax jurisdictions. In preparing the Company's financial statements, the Company estimates the amount of tax that will become payable, but the Company's effective tax rate may be different than estimates due to numerous factors including accounting for income taxes, the mix of earnings from Japan and the U.S., the results of tax audits, adjustments to the value of uncertain tax positions, changes to estimates and other factors. Further, changes in U.S. or Japan tax laws or interpretations of such laws could increase the Company's corporate taxes and reduce earnings.

In addition, it remains difficult to predict the timing and effect that future tax law changes could have on the Company's earnings both in the U.S. and in foreign jurisdictions. Any of these factors could cause the Company to experience an effective tax rate significantly different from previous periods or the Company's current estimates. If the Company's effective tax rate were to increase, the Company's financial condition and results of operations could be adversely affected.



23
If the Company fails to comply with restrictions on customer privacy and information security, including taking steps to ensure that its third-party service providers and business associates who access, store, process or transmit sensitive customer information maintain its security, integrity, confidentiality and availability, the Company's reputation and business operations could be materially adversely affected.

The collection, maintenance, use, protection, disclosure and disposal of individually identifiable data by the Company's businesses are regulated at the international, federal and state levels. These laws and rules are subject to change by legislation or administrative or judicial interpretation. With regard to personal information obtained from policyholders, the insured, or others, Aflac Japan is regulated in Japan by the APPI and guidelines issued by FSA and other governmental authorities.

Various state laws in the U.S. address the unauthorized access and acquisition of personal information and the use and disclosure of individually identifiable health data. HIPAA requires the Company to impose privacy and security requirements on its business associates (as such term is defined in the HIPAA regulations). A number of states, including California and New York, have adopted and continue to expand their privacy and cybersecurity laws and regulations in recent years. Additionally, the U.S. Congress and many states are considering new privacy and security requirements that would apply to the Company's business. Compliance with new privacy and security laws, requirements, and new regulations may result in cost increases due to necessary systems changes, new limitations or constraints on the Company's business models, the development of new administrative processes, and the effects of potential noncompliance by the Company's business associates. They also may impose further restrictions on the Company's collection, disclosure and use of customer identifiable data that are housed in one or more of the Company's administrative databases. Noncompliance with any privacy laws or any security breach involving the misappropriation, loss, theft or other unauthorized disclosure of sensitive or confidential customer information, whether by the Company or by one of its third parties, could have a material adverse effect on the Company's business, reputation, brand and results of operations, including: material fines and penalties; compensatory, special, punitive and statutory damages; consent orders regarding the Company's privacy and security practices; adverse actions against the Company's licenses to do business; and injunctive relief.

Under Japanese laws and regulations, including the APPI, if a leak or loss of personal information by Aflac Japan or its business associates should occur, depending on factors such as the volume of personal data involved and the likelihood of other secondary damage, Aflac Japan may be required to file reports to the FSA; issue public releases explaining such incident to the public; or become subject to an FSA business improvement order, which could pose a risk to the Company's reputation.

Although the Company provides for appropriate protections through its contracts and performs information security risk assessments of its third-party service providers and business associates, the Company still has limited control over their actions and practices. In addition, despite the security measures the Company has in place to ensure compliance with applicable laws and rules, the Company's facilities and systems, and those of the Company's third-party providers and participants in its distribution channels may be vulnerable to security breaches, acts of vandalism or theft, computer viruses, misplaced or lost data, programming and/or human errors or other similar events. From time to time, the Company, its third-party providers and participants in the Company’s distribution channels have experienced and will likely continue to experience such events. In such cases, notification to affected individuals, state and federal regulators, state attorneys general and media may be required, depending upon the number of affected individuals and whether personal information including health or financial data was subject to unauthorized access.

Extensive regulation and changes in legislation can impact profitability and growth.

The Company and its insurance subsidiaries are subject to complex laws and regulations that are administered and enforced by a number of governmental authorities, that exercise a degree of interpretive latitude, including the FSA and Ministry of Finance (MOF) in Japan, state insurance regulators, the BMA in Bermuda, the SEC, the NAIC, the FIO, the U.S. Department of Justice, state attorneys general, the U.S. Commodity Futures Trading Commission, and the U.S. Department of the Treasury, including the Internal Revenue Service (IRS), in the U.S. The Company is subject to the risk that compliance with any particular regulator's or enforcement authority's interpretation of a legal or regulatory issue may result in non-compliance with another regulator's or enforcement authority's interpretation of the same issue, particularly when compliance is judged in hindsight. Further, regulatory authorities periodically re-examine existing laws and regulations applicable to insurance companies and their products. Changes in these laws and regulations, or in interpretations thereof, could have a material adverse effect on the Company's financial condition and results of operations.



24
Additionally, changes in the overall legal or regulatory environment may, even absent any particular regulator's or enforcement authority's interpretation of an issue changing, cause the Company to change its views regarding the actions it needs to take from a legal or regulatory risk management perspective. This may necessitate changes to the Company's practices that may, in some cases, limit its ability to grow or otherwise negatively impact the profitability of the Company's business.

If the Company's subsidiaries fail to meet the minimum capital or operational requirements established by its respective regulators, they could be subject to examination or corrective action, or the Company's financial strength ratings could be downgraded, or both. Compliance with applicable laws and regulations is time consuming and personnel-intensive, and changes in these laws and regulations may materially increase the Company's direct and indirect compliance and other expenses of doing business, thus having a material adverse effect on the Company's financial condition and results of operations. For additional information, see the Government Regulation subsections of Item 1. Business.

General Risk Factors

Competition could adversely affect the Company's ability to increase or maintain its market share or profitability.

The Company operates in a competitive environment and in an industry that is subject to ongoing changes from market pressures brought about by customer demands, legislative reform, marketing practices and changes to health care and health insurance delivery. These factors require the Company to anticipate market trends and make changes to differentiate the Company's products and services from those of its competitors. The Company also faces potential competition from existing or new companies in the U.S. and Japan that have not historically been active in the supplemental health insurance industry, but some of which have greater financial, marketing and management resources than the Company. Further, some of these potential competitors could introduce new means of product development and delivery that disrupt the Company’s business model. Failure to anticipate market trends and/or to differentiate the Company's products and services can affect the Company's ability to retain or grow profitable lines of business. Further, as employers and brokers are increasingly requesting a full suite of products from one insurance provider, a failure to react and adapt to these demands could result in decreased sales or market share.

The Company's future success will depend, in part, on its ability to keep pace with rapid technological changes and to use technology to satisfy and grow customer demand for the Company's products and services and to create additional efficiencies in its operations. The Company may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers. A failure to meet evolving customer demands through innovative product development, effective distribution channels, and continuous investment in the Company's technology could adversely affect the Company's operating results. Further, the evolving fragmentation of media and marketing channels that has developed over recent years could weaken the impact of the Company’s advertising efforts over time. As a result, the Company's ability to effectively compete to retain or acquire new business may be impaired, and its business, financial condition or results of operations may be adversely affected.

Catastrophic events could adversely affect the Company's financial condition and results of operations as well as the availability of the Company’s infrastructure and systems.

The Company's insurance operations are exposed to the risk of catastrophic events including, but not necessarily limited to, epidemics, pandemics, tornadoes, hurricanes, earthquakes, tsunamis, war or other military action, major public health issues and terrorism or other acts of violence. Claims resulting from natural or man-made catastrophic events could cause substantial volatility in the Company's financial results for any fiscal quarter or year and could materially reduce its profitability or harm the Company's financial condition, as well as affect its ability to write new business. In addition, such events may lead to periods of voluntary or required premium grace periods, which may lead to volatility in lapse rates and related premiums. Any resulting or coincidental economic effects could impact the Company's business, financial condition, results of operations, capital position, liquidity or prospects in a number of ways. These catastrophic events may cause changes to estimates of future earnings, capital deployment and other guidance the Company has provided to the markets in the 2026 Outlook section of Item 7. MD&A.

Additionally, the Company's operations, as well as those of its vendors, service providers and counterparties, may be adversely affected by such catastrophic events to the extent they disrupt the Company's physical infrastructure, human resources or systems that support its businesses and customers. Although the Company has a global crisis management framework to minimize the business disruption from a catastrophic event, such framework may not be effective to avoid an adverse impact to the Company from such an event. While the assessment of risks related to climate change are part of the Company's credit review process, climate change-related risks may adversely impact the value of the securities that


25
the Company holds. Further, the Company cannot predict the effects that any legal or regulatory changes made in response to climate change concerns or major public health issues would have on the Company's business.

Events, including those external to the Company's operations, could damage the Company's reputation.

The Company has made significant investments in the Aflac brand over a long period of time. Because insurance products are intangible, the Company's ability to compete for and maintain policyholders relies to a large extent on consumer trust in the Company's business, including its alliance partners, sales associates and other distribution partners. The perception of unfavorable business practices or financial weakness with respect to the Company, its alliance partners, sales associates or other distribution partners could create doubt regarding the Company's ability to honor the commitments it has made to its policyholders. Such perceptions could also negatively impact the Company’s ability to attract and retain qualified sales associates, brokers and other distribution partners, including its alliance partners in Japan, and could have a material adverse effect on the Company's sales, results of operations and financial condition. These effects could also result from a perception of a lack of commitment to sustainability efforts and attention to societal impacts, unfavorable positions on items of public policy, or from failure to make progress toward the Company's sustainability goals. Maintaining the Company's stature as a trustworthy insurer and responsible corporate citizen, which helps support the strength of the Company's brand, is critical to the Company's reputation and the failure or perceived failure to do so could adversely affect the Company's brand value, financial condition and results of operations.

The Company depends heavily on key management personnel, and the loss of services of one or more of its key executives could harm the Company's business.

The Company’s success depends to a significant extent on the efforts and abilities of its key management personnel. The loss of the services of one or more of the Company's senior executives could significantly undermine its management expertise, and the Company's business could be adversely affected.

Changes in accounting standards issued by the Financial Accounting Standards Board (FASB) or other standard-setting bodies may adversely affect the Company's financial statements.

The Company's financial statements are subject to the application of U.S. GAAP, which is periodically revised and/or expanded. Accordingly, from time to time the Company is required to adopt new or revised accounting standards issued by recognized authoritative bodies, including the FASB. Changes to accounting standards could have a material adverse effect on the Company's results of operations and financial condition. For additional information, see Note 1 of the Notes to the Consolidated Financial Statements.

The Company faces risks related to litigation, regulatory investigations and inquiry and other matters.

The Company is a defendant in various lawsuits considered to be in the normal course of business. The final results of any litigation cannot be predicted with certainty, and plaintiffs may seek very large amounts in class actions or other litigation. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows. However, a substantial legal liability or a significant federal, state or other regulatory action against the Company, as well as regulatory inquiries or investigations, could harm the Company's reputation, result in changes in operations, result in material fines or penalties, result in significant costs due to legal fees, settlements or judgments against the Company, or otherwise have a material adverse effect on the Company's business, financial condition and results of operations. Without limiting the foregoing, the litigation and regulatory matters the Company is, has been, or may become, subject to include matters related to sales agent recruiting, policy sales practices, claim payments and procedures including denial or delay of benefits, the low level of Aflac U.S. benefit ratios in recent financial periods, material misstatements or omissions in the Company's financial reports or other public statements, and/or corporate governance, corporate culture or business ethics matters. Further, the Company may be subject to claims of or litigation regarding sexual or other forms of misconduct or harassment, or discrimination on the basis of race, color, national origin, religion, gender, or other bases, notwithstanding that the Company's Code of Business Conduct and Ethics prohibits such harassment and discrimination by its employees, the Company has ongoing training programs and provides opportunities to report claims of noncompliant conduct, and it investigates and may take disciplinary action regarding alleged harassment or discrimination. Any violations of or deviation from laws, regulations, internal or external codes or standards of normative behavior, or perceptions of such violations or deviations, by the Company's employees or by independent sales agents could adversely impact the Company's reputation and brand value, financial condition and results of operations.



26
Allegations or determinations of agent misclassification could adversely affect the Company’s results of operations, financial condition and liquidity.

A majority of the Company's U.S. sales force is, and has historically been, comprised of independent agents. While the Company believes that it has properly classified such agents as independent contractors, the Company may be subject to claims, regulatory action by state or federal departments of labor or tax authorities, changes in state or federal law, or litigation asserting that such agents are employees. The laws and regulations governing the classification of workers in the U.S. may be changed or interpreted differently compared to past interpretations, including in states where the Company generates significant sales through independent agents. An allegation or determination that independent agents in the Company’s U.S. sales force have been misclassified as independent contractors could result in changes in the Company’s operations and U.S. business model, result in material fines or penalties, result in significant costs due to legal fees, settlements or judgments against the Company, or otherwise have a material adverse effect on the Company's business, results of operation, financial condition and liquidity.

ITEM 1B. UNRESOLVED STAFF COMMENTS

Not applicable.

ITEM 1C. CYBERSECURITY

The Company’s board of directors maintains an information security policy directing management to establish and operate a global information security program with the goals of identifying, assessing and monitoring existing and emerging cybersecurity threats and ensuring that the Company’s information assets and data, and the data of its customers, are appropriately protected from loss or theft. The Board has delegated oversight of the Company’s information security program to the Audit and Risk Committee.

The Company’s senior officers, including its Global Chief Information Security Officer (GCISO), are responsible for the operation of the global information security program and communicate quarterly with the Audit and Risk Committee on the program, including with respect to the state of the program, compliance with applicable regulations, risks associated with current and evolving threats, and recommendations for changes in the information security program. The global information security program includes a cybersecurity incident response plan that is designed to provide a management framework across Company functions for a coordinated assessment and response to cybersecurity incidents. This framework establishes a protocol to report certain incidents to the GCISO and other senior officers, with the goal of timely assessing such incidents, determining applicable disclosure requirements, and communicating with the Board of Directors as appropriate. The incident response plan directs the executive officers to report certain incidents immediately and directly to the Lead Non-Management Director and/or the Chair of the Audit and Risk Committee. The above framework tracks and allows team members to monitor each incident throughout its lifecycle to help ensure the Company is informed about cybersecurity incidents as they are mitigated and remediated. Post-incident reviews are also performed as appropriate to identify potential additional controls that may feasibly be implemented to help prevent recurrence.

As a part of the global information security program, an enterprise cybersecurity risk assessment is performed annually in coordination with the GCISO to identify and assess cybersecurity risks and mitigating controls. The assessment results are incorporated into a risk register managed by the Company’s overall enterprise risk management group to integrate the risks into the overall risk management processes. The Company engages with independent firms to conduct operational control assessments, which cover information protection. Periodically, the Company engages independent consultants to review certain aspects of the cyber program. Additionally, the Company performs third-party risk assessments to evaluate security controls and identify inherent and residual risks associated with third-party engagements. Issues identified during third-party risk assessments are documented and escalated to Company management through an established committee structure based on the risk ratings associated with each issue.

The Company also utilizes professionals from the Company’s legal team and GCISO's leadership team, a majority of whom have specialized skills and knowledge in cybersecurity risk management based on their prior work experience and relevant industry certifications, such as Certified Information Systems Security Professional and Certified Information Security Manager, to assist in employee awareness and training, as well as assessing cybersecurity risks, materiality of cybersecurity incidents and disclosures of the same. Specifically, the GCISO has security experience in the public sector and private sector financial services industry holding positions in areas such as business continuity, information assurance, and technology risk management as well as being a Certified Information Systems Security Professional, Certified Information Security Manager and Certified Project Manager as well as being certified in Risk and Information


27
Systems Control. The GCISO and the senior security leadership team have an average of over 20 years of experience in the field of cybersecurity.

As of the date of this Form 10-K, the Company is not aware of any cybersecurity incidents that occurred during the year ended December 31, 2025 that have materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial condition and that are required to be reported in this Form 10-K.

For further discussion of the risks associated with cybersecurity incidents, see Item 1A. Risk Factors for the risk factor titled "Interruption in telecommunication, information technology and other operational systems, or a failure to maintain the security, confidentiality, integrity or privacy of sensitive data residing on such systems, could harm the Company's business" for additional information regarding how the Company's business strategy, results of operations, and financial condition could be adversely affected by risks from cybersecurity threats.

ITEM 2. PROPERTIES

In Tokyo, Japan, the Company has two primary campuses. The first campus includes a building, owned by the Company, for the customer call center, the claims department, the information technology departments, and a training facility. This campus also includes a leased property, which houses Aflac Japan's policy administration and customer service departments. The second campus comprises leased office space, which serves as Aflac Japan's headquarters and houses administrative and investment support functions. The Company also leases additional office space in Tokyo, along with regional offices located throughout the country.
In the U.S., the Company owns land and buildings that comprise two primary campuses located in Columbus, Georgia. These campuses include buildings that serve as the Company's worldwide headquarters and house administrative support and information technology functions for U.S. operations. The Company leases office space in Columbia, South Carolina, which houses the Company's CAIC subsidiary (branded as Aflac Group Insurance); in New York, New York, which houses the Company's Global Investment division; in Tampa, Florida, which houses the Company's ABS subsidiary; and in Windsor, Connecticut and Plantation, Florida, which house the operations of the Company's group life, disability and absence management business. The Company leases other administrative office space throughout the U.S., the United Kingdom, and Bermuda.
The Company believes its properties are adequate and suitable for its business as currently conducted and are adequately maintained.
ITEM 3. LEGAL PROCEEDINGS

The Company is a defendant in various lawsuits and receives various regulatory inquiries considered to be in the normal course of business. Members of the Company's senior legal and financial management teams review litigation and regulatory inquiries on a quarterly and annual basis and the Company updates the related estimates, accruals, and disclosures, if any, based on such reviews. For litigation and regulatory matters where it is probable that a loss has been incurred, and the amount of that loss can be reasonably estimated, the Company establishes accruals for loss contingencies. Where a loss may be reasonably possible but not probable, or is probable but not reasonably estimable, no accrual is recorded. The final results of any litigation or regulatory inquiries cannot be predicted with certainty. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows.

EXECUTIVE SUMMARY

Performance Highlights

For the full year of 2025, total revenues were down 9.3% to $17.2 billion, compared with $18.9 billion for the full year of 2024, primarily due to net investment losses of $572 million in 2025 compared with net investment gains of $1.3 billion in 2024. Net earnings were $3.6 billion, or $6.82 per diluted share, for the full year of 2025, compared with $5.4 billion, or $9.63 per diluted share, for the full year of 2024.

Net earnings in 2025 included net investment losses of $572 million, compared with net investment gains of $1.3 billion in 2024. Net investment losses in 2025 included $467 million of net losses from certain derivative and foreign currency gains or losses; an increase in credit loss allowances of $191 million and $6 million of impairments; offset by a $72 million gain from an increase in the fair value of equity securities and $20 million of net gains from sales and redemptions.

The average yen/dollar exchange rate(1) in 2025 was 149.32, or 1.1% stronger than the rate of 150.97 in 2024.

Adjusted earnings(2) for the full year of 2025 were $4.0 billion, or $7.49 per diluted share, compared with $4.1 billion, or $7.21 per diluted share, in 2024. The stronger yen/dollar exchange rate positively impacted adjusted earnings per diluted share by $.04.

In 2025, Aflac Incorporated repurchased $3.5 billion, or 33.0 million of its common shares. At December 31, 2025, the Company had 114.3 million remaining shares authorized for repurchase.

Shareholders’ equity was $29.5 billion, or $56.85 per share, at December 31, 2025, compared with $26.1 billion, or $47.45 per share, at December 31, 2024. Shareholders’ equity at December 31, 2025 included a cumulative increase of $8.0 billion from the effect of changes in discount rate assumptions on insurance reserves, compared with a corresponding cumulative increase of $2.0 billion at December 31, 2024, and a net unrealized loss on investment securities and derivatives of $1.8 billion, compared with a net unrealized gain of $4 million at December 31, 2024. Shareholders’ equity at December 31, 2025 also included an unrealized foreign currency translation loss of $4.8 billion, compared with an unrealized foreign currency translation loss of $5.0 billion at December 31, 2024. The annualized return on average shareholders’ equity in 2025 was 13.1%.

Shareholders’ equity excluding accumulated other comprehensive income (adjusted book value(2)) was $28.0 billion, or $54.06 per share, at December 31, 2025, compared with $29.1 billion, or $52.87 per share, at December 31, 2024. Adjusted book value excluding foreign currency remeasurement(2) was $22.1 billion, or $42.66 per share, at December 31, 2025, compared with $23.4 billion, or $42.46 per share, at December 31, 2024. The annualized adjusted return on equity excluding foreign currency remeasurement(2) in 2025 was 17.6%.

Cyber Incident

As previously disclosed, the Company identified an incident involving unauthorized access to a limited number of its systems in the U.S. on June 12, 2025. The Company promptly initiated its cybersecurity incident response protocols and believes it contained the unauthorized access within hours. The Company's systems were not affected by ransomware, and the Company remained able to serve its policyholders and underwrite policies, review claims, and otherwise service customers as usual.

The Company is aware of the exfiltration of certain data including claims information, health information, social security numbers and/or other personal information relating to a substantial number of customers, beneficiaries, employees, agents, and other individuals in the Company’s U.S. business. In December 2025, the Company completed a detailed review of the potentially impacted files and determined that personal information associated with approximately 22.65 million individuals was involved, and began notifying impacted individuals and regulatory authorities as required by applicable laws.

Based on the information currently available, as of the date of this report, the Company does not believe that the incident is reasonably likely to have a material impact on the Company’s financial condition or results of operations. The Company continues to assess the financial impact of the cybersecurity incident, including how much of the financial impact will be covered by insurance. As a result of the cybersecurity incident, the Company has incurred certain costs and may,


33
depending on future developments, incur additional costs, including but not limited to: costs to provide credit monitoring, identity theft protection, and Medical Shield to impacted individuals and maintain a call center related to the provision of such services; incident response costs; expenses arising from potential litigation, governmental investigations, or enforcement actions; expenses related to compliance, finance, and legal advisory services; elevated cybersecurity insurance premiums; and costs incurred in meeting evolving legal and regulatory requirements concerning cybersecurity governance, monitoring, and disclosure. The costs associated with the incident to date, including the cost to investigate and respond to the incident as well as related legal and other professional services, resulted in a slight increase to the Company's expenses and are recorded in the insurance and other expenses line in the consolidated statement of earnings.

INDUSTRY TRENDS

The Company is impacted by financial markets, economic conditions, regulatory oversight and a variety of trends that affect the industries where it competes.

Financial and Economic Environment

The Company’s business and results of operations are materially affected by conditions in the global capital markets and the economy generally. Stressed conditions, volatility and disruptions in global capital markets, particular markets, or financial asset classes can have an adverse effect on the Company, in part because the Company has a large investment portfolio and its insurance liabilities and derivatives are sensitive to changing market factors. See Item 1A. Risk Factors for the risk factor entitled, "Difficult conditions in global capital markets and the economy could have a material adverse effect on the Company's investments, capital position, revenue, profitability, and liquidity and harm the Company's business."

Demographics

Aflac Japan Segment

With Japan’s aging population and the rise in healthcare costs, supplemental health care insurance products remain attractive. Additionally, as Japan enters an era of 100-year lifespans, customers' needs for asset formation and retirement coverage, including nursing care, are increasing. Japan’s existing customers and potential customers seek products that are easily understood, affordable and accessible via digital platforms.

Aflac U.S. Segment

Customer demographics continue to shift, generating new opportunities across various consumer groups, including millennials and diverse cultural communities. As customer expectations and preferences change, trends indicate that both existing and potential customers seek affordable options that are easily understood and accessible via digital platforms. Furthermore, the insurance industry continues to be impacted by the financial security requirements and healthcare demands of the aging baby boomer generation.

Regulatory Environment

See Item 1. Business - Aflac Japan Government Regulation and Aflac U.S. Government Regulation for a discussion of regulatory developments that may impact the Company and the associated risks.

Competitive Environment

See Item 1. Business - Aflac Japan Competitive Markets and Aflac U.S. Competitive Markets for a discussion of the competitive environment and the basis on which the Company competes in each of its segments.

2026 OUTLOOK

The Company’s strategy to drive long-term shareholder value is to pursue growth and maintain solid pretax profit margins while exercising tactical capital deployment. The Company's approach to pursue growth is through product development and distribution expansion, along with enhanced efficiency through technological upgrades and operational refinement.

The Company's objectives in 2026 include preserving solid pretax profit margins with increased sales production achieved through the ongoing promotional efforts for products launched in 2025 in Aflac Japan and continued growth initiatives across both its Aflac Japan and Aflac U.S. segments. The Company believes this strategy positions it for future growth


34
and efficiency while defending and leveraging its market-leading position, powerful brand recognition and varied distribution in Japan and the U.S.

In November 2025, the board of directors announced a 5.2% increase in the quarterly cash dividend, effective with the first quarter of 2026. The Company intends to maintain strong capital ratios in Aflac Japan and Aflac U.S. in support of its commitment to shareholder dividends while remaining tactical in its deployment of capital in the form of share repurchases and opportunistic investments. The Company's target range for economic solvency ratio (ESR) is 170% to 230% for Aflac Japan and a target combined RBC range of 350% to 450%, over time, for Aflac U.S., which are consistent with the Company's risk management practices.

Aflac Japan Segment
For 2026, the Company expects Aflac Japan to generate a benefit ratio in the range of 60% to 63% driven by favorable trends in morbidity experience, new product launches featuring lower benefit ratios, and the premium shift over recent years from first sector savings products to third sector cancer and medical products, as well as first sector protection products. The Company expects Aflac Japan to generate an expense ratio in the range of 20% to 23% reflecting continued growth and strategic initiatives. The Company also expects that benefit and expense ratios will continue to experience some level of revenue pressure due to the impact of paid-up policies and internal reinsurance transactions.

Aflac U.S. Segment
For 2026, the Company expects Aflac U.S. to generate a benefit ratio in the range of 48% to 52% driven by growth in life, disability, and dental and vision insurance products, all of which typically carry higher benefit ratios. The Company expects Aflac U.S. to generate an expense ratio in the range of 36% to 39%. However, continued revenue growth associated with these products is expected to decrease expense ratios over time.

Corporate and other
The Company's objectives for Corporate and other in 2026 include achieving solid pretax adjusted earnings, assuming that U.S. interest rates remain stable and excluding the impact of tax credit investments, as tax benefits are recognized in a corresponding lower income tax expense.

For important disclosures applicable to statements made in this 2026 Outlook, please see the statement on Forward-Looking Information at the beginning of Item 1. Business, the Risk Factors identified in Item 1A. and this Item 7. MD&A.

RESULTS OF OPERATIONS

The Company earns its revenues principally from insurance premiums and investments. The Company’s operating expenses primarily consist of insurance benefits provided and reserves established for anticipated future insurance benefits, general business expenses, commissions and other costs of selling and servicing its products. Profitability for the Company depends principally on its ability to price its insurance products at a level that enables the Company to earn a margin over the costs associated with providing benefits and administering those products. Profitability also depends on, among other items, actuarial and policyholder behavior experience on insurance products, and the Company's ability to attract and retain customer assets, generate and maintain favorable investment results, effectively deploy capital and utilize tax capacity, and manage expenses.

This document includes references to the Company’s financial performance measures which are not calculated in accordance with United States generally accepted accounting principles (U.S. GAAP) (non-U.S. GAAP). The financial measures exclude items that the Company believes may obscure the underlying fundamentals and trends in insurance operations because they tend to be driven by general economic conditions and events or related to infrequent activities not directly associated with insurance operations.

Due to the size of Aflac Japan, where the functional currency is the Japanese yen, fluctuations in the yen/dollar exchange rate can have a significant effect on reported results. In periods when the Japanese yen weakens, translating Japanese yen into U.S. dollars results in fewer U.S. dollars being reported. When the Japanese yen strengthens, translating Japanese yen into U.S. dollars results in more U.S. dollars being reported. Consequently, Japanese yen weakening has the effect of suppressing current period results in relation to the comparable prior period, while Japanese yen strengthening has the effect of magnifying current period results in relation to the comparable prior period. A significant portion of the Company’s business is conducted in Japanese yen and never converted into U.S. dollars but translated into U.S. dollars for U.S. GAAP reporting purposes, which results in foreign currency impact to earnings, cash flows and book


35
value on a U.S. GAAP basis. Management evaluates the Company's financial performance both including and excluding the impact of foreign currency translation to monitor, respectively, cumulative currency impacts and the currency-neutral operating performance over time. The average yen/dollar exchange rate is based on the published MUFG Bank, Ltd. telegraphic transfer middle rate (TTM).

The Company defines the non-U.S. GAAP financial measures included in this document as follows:

•Adjusted earnings are adjusted revenues less benefits and adjusted expenses. Adjusted earnings per share (basic or diluted) are the adjusted earnings for the period divided by the weighted average outstanding shares (basic or diluted) for the period presented. The adjustments to both revenues and expenses account for certain items that are outside of management’s control because they tend to be driven by general economic conditions and events or are related to infrequent activities not directly associated with insurance operations. Adjusted revenues are U.S. GAAP total revenues excluding adjusted net investment gains and losses. Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest from derivatives associated with notes payable but excluding any non-recurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company's underlying business performance. Management uses adjusted earnings and adjusted earnings per diluted share to evaluate the financial performance of the Company’s insurance operations on a consolidated basis and believes that a presentation of these financial measures is vitally important to an understanding of the underlying profitability drivers and trends of the Company’s insurance business. The most comparable U.S. GAAP financial measures for adjusted earnings and adjusted earnings per share (basic or diluted) are net earnings and net earnings per share, respectively.

•Adjusted net investment gains and losses are net investment gains and losses adjusted for i) amortized hedge cost/income related to foreign currency exposure management strategies and certain derivative activity, ii) net interest income/expense from foreign currency and interest rate derivatives associated with certain investment strategies, which are both reclassified to net investment income, and iii) the impact of interest from derivatives associated with notes payable, which is reclassified to interest expense as a component of total adjusted expenses. The Company considers adjusted net investment gains and losses important as it represents the remainder amount that is considered outside management’s control, while excluding the components that are within management’s control and are accordingly reclassified to net investment income and interest expense. The most comparable U.S. GAAP financial measure for adjusted net investment gains and losses is net investment gains and losses.

•Amortized hedge costs/income represent costs/income incurred or recognized as a result of using foreign currency derivatives to hedge certain foreign currency exchange risks in the Company's Japan segment or in Corporate and other. These amortized hedge costs/income are estimated at the inception of the derivatives based on the specific terms of each contract and are recognized on a straight-line basis over the contractual term of the derivative. The Company believes that amortized hedge costs/income measure the periodic currency risk management costs/income related to hedging certain foreign currency exchange risks and are an important component of net investment income. There is no comparable U.S. GAAP financial measure for amortized hedge costs/income.

•Adjusted earnings excluding current period foreign currency impact are computed using the average foreign exchange rate for the comparable prior-year period, which eliminates fluctuations driven solely by foreign exchange rate changes. Adjusted earnings per diluted share excluding current period foreign currency impact is adjusted earnings excluding current period foreign currency impact divided by the weighted average outstanding diluted shares for the period presented. The Company considers adjusted earnings excluding current period foreign currency impact and adjusted earnings per diluted share excluding current period foreign currency impact important because a significant portion of the Company's business is conducted in Japan and foreign exchange rates are outside management’s control; therefore, the Company believes it is important to understand the impact of translating foreign currency (primarily Japanese yen) into U.S. dollars. The most comparable U.S. GAAP financial measures for adjusted earnings excluding current period foreign currency impact and adjusted earnings per diluted share excluding current period foreign currency impact are net earnings and net earnings per share, respectively.

•Adjusted book value is the U.S. GAAP book value (representing total shareholders’ equity), less accumulated other comprehensive income as recorded on the U.S. GAAP balance sheet. Adjusted book value per common share is adjusted book value at the period end divided by the ending outstanding common shares for the period presented. The Company considers adjusted book value and adjusted book value per common share important


36
as they exclude accumulated other comprehensive income, which fluctuates due to market movements that are outside management’s control. The most comparable U.S. GAAP financial measures for adjusted book value and adjusted book value per common share are total book value and total book value per common share, respectively.

•Adjusted book value excluding foreign currency remeasurement is the U.S. GAAP book value (representing total shareholders’ equity), less accumulated other comprehensive income as recorded on the U.S. GAAP balance sheet and excluding the cumulative (beginning January 1, 2021) foreign currency gains/losses associated with i) foreign currency remeasurement and ii) sales and redemptions of invested assets. Adjusted book value excluding foreign currency remeasurement per common share is adjusted book value excluding foreign currency remeasurement at the period end divided by the ending outstanding common shares for the period presented. The Company considers adjusted book value excluding foreign currency remeasurement and adjusted book value excluding foreign currency remeasurement per common share important as they exclude both accumulated other comprehensive income and the cumulative foreign currency remeasurement gains/losses, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measures for adjusted book value excluding foreign currency remeasurement and adjusted book value excluding foreign currency remeasurement per common share are total book value and total book value per common share, respectively.

•Adjusted return on equity is annualized adjusted earnings divided by average shareholders’ equity, excluding accumulated other comprehensive income. Management uses adjusted return on equity to evaluate the financial performance of the Company’s insurance operations on a consolidated basis and believes that a presentation of this financial measure is vitally important to an understanding of the underlying profitability drivers and trends of the Company’s insurance business. The Company considers adjusted return on equity important as it excludes components of accumulated other comprehensive income, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measure for adjusted return on equity is return on equity as determined using annualized net earnings and average total shareholders’ equity.

•Adjusted return on equity excluding foreign currency remeasurement is annualized adjusted earnings divided by average shareholders’ equity, excluding both accumulated other comprehensive income and the cumulative (beginning January 1, 2021) foreign currency gains/losses associated with i) foreign currency remeasurement and ii) sales and redemptions of invested assets. The Company considers adjusted return on equity excluding foreign currency remeasurement important because it excludes both accumulated other comprehensive income and the cumulative foreign currency remeasurement gains/losses, which fluctuate due to market movements that are outside management's control. The most comparable U.S. GAAP financial measure for adjusted return on equity excluding foreign currency remeasurement is return on equity as determined using annualized net earnings and average total shareholders’ equity.

•U.S. dollar-denominated investment income excluding foreign currency impact represents amounts excluding foreign currency impact on U.S. dollar-denominated investment income using the average foreign exchange rate for the comparable prior year period. The Company considers U.S. dollar-denominated investment income excluding foreign currency impact important as it eliminates the impact of foreign currency changes on the Aflac Japan segment results, which are outside management’s control. The most comparable U.S. GAAP financial measure for U.S. dollar-denominated investment income excluding foreign currency impact is the corresponding net investment income amount from the U.S. dollar denominated investments translated to yen.

The Company's investment strategy is to invest primarily in fixed maturity securities to provide a reliable stream of investment income, which is one of the drivers of the Company’s profitability. This investment strategy incorporates asset-liability matching to align the expected cash flows of the portfolio to the needs of the Company's liability structure. The Company does not purchase securities with the intent of generating investment gains or losses. However, investment gains and losses may be realized as a result of changes in the financial markets and the creditworthiness of specific issuers, tax planning strategies, and/or general portfolio management and rebalancing. The realization of investment gains and losses is independent of the underwriting and administration of the Company's insurance products.

Net investment gains and losses excluded from adjusted earnings include the following:

•Securities Transactions
•Credit Losses
•Changes in the Fair Value of Equity Securities
•Certain Derivative and Foreign Currency Activities.



38
Securities Transactions, Credit Losses and Changes in the Fair Value of Equity Securities

Securities transactions include gains and losses from sales and redemptions of investments where the amount received is different from the amortized cost of the investment. Credit losses include losses for held-to-maturity securities, available-for-sale securities, loan receivables, loan commitments and reinsurance recoverables. Changes in the fair value of equity securities are the result of gains or losses driven by fluctuations in market prices.

Certain Derivative and Foreign Currency Activities

The Company's derivative activities include:

•foreign currency forwards and options used in hedging foreign currency exchange risk on U.S. dollar-denominated investments held by Aflac Japan, with options used on a standalone basis and/or in a collar strategy;
•foreign currency forwards and options used to economically hedge certain portions of forecasted cash flows denominated in Japanese yen and hedge the Company's long-term exposure to a weakening Japanese yen;
•foreign currency swaps used to economically hedge the foreign currency exchange risk associated with certain investments denominated in other foreign currencies held by Aflac Japan;
•cross-currency swaps, also referred to as foreign currency swaps, associated with certain senior notes and subordinated debentures;
•foreign currency swaps that are associated with variable interest entity (VIE) bond purchase commitments, and investments in special-purpose entities, including VIEs where the Company is the primary beneficiary;
•foreign currency forwards used to economically hedge the foreign currency exchange risk associated with certain investments denominated in other foreign currencies held by Aflac Japan;
•interest rate swaps used to economically hedge interest rate fluctuations in certain variable-rate investments;
•interest rate swaptions (swaptions) used to hedge changes in the fair value associated with interest rate fluctuations for certain U.S. dollar-denominated available-for-sale securities; and
•bond purchase commitments at the inception of investments in consolidated VIEs.

Gains and losses are recognized as a result of valuing these derivatives, net of the effects of hedge accounting.

The Company also excludes from adjusted earnings the accounting impacts of foreign currency remeasurement associated with changes in the foreign exchange rate.

For additional information regarding net investment gains and losses, including details of reported amounts for the periods presented, see Notes 3 and 4 of the Notes to the Consolidated Financial Statements.

Other and Non-recurring Items

The U.S. insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. The system can result in periodic charges to the Company as a result of insolvencies/bankruptcies that occur with other companies in the life insurance industry. Some states permit member insurers to recover assessments paid through full or partial premium tax offsets. These charges neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, but result from external situations not controlled by the Company. The Company excludes any charges associated with U.S. guaranty fund assessments and the corresponding tax benefit or expense from adjusted earnings.

In Japan, the government also requires the insurance industry to contribute to a policyholder protection corporation that provides funds for the policyholders of insolvent insurers; however, these costs are calculated and administered differently than in the U.S. In Japan, these costs are not directly related to specific insolvencies or bankruptcies, but are rather a regular operational cost for an insurance company. Based on this structure, the Company does not remove the Japan policyholder protection expenses from adjusted earnings.

The Company considers the costs associated with the early redemption of its debt to be unrelated to the underlying fundamentals and trends in its insurance operations. Additionally, these costs are driven by changes in interest rates subsequent to the issuance of the debt, and the Company considers these interest rate changes to represent economic conditions not directly associated with its insurance operations.


39

In 2025, as part of the U.S. defined benefit plan freeze effective January 1, 2024, the Company purchased a nonparticipating single premium group annuity contract from an external insurer to settle its obligations under the plan and paid to the insurer the related annuity premium. As a result, the Company recognized a settlement charge of $55 million in 2025. The settlement charge was both unusual and non-recurring; therefore, the Company excluded the settlement charge from adjusted earnings.

In 2024, as part of the U.S. defined benefit plan freeze effective January 1, 2024, the Company offered lump sum payments to certain participants. The lump sum payments were distributed in the fourth quarter of 2024 and resulted in a settlement charge of $18 million in 2024 due to the payments being greater than the settlement threshold. The settlement charge was both unusual and non-recurring and unrelated to other recurring benefit costs associated with the plan; therefore, the Company excluded the settlement charge from adjusted earnings.

Foreign Currency Translation

Aflac Japan’s premiums and a significant portion of its investment income are received in Japanese yen, and its claims and most expenses are paid in Japanese yen. Aflac Japan purchases Japanese yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to Japanese yen, to support Japanese yen-denominated policy liabilities. Japanese yen-denominated income statement accounts are translated to U.S. dollars using the weighted average yen/dollar foreign exchange rate for the reporting period, except realized gains and losses on securities transactions which are translated at the foreign exchange rate on the trade date of each transaction. Japanese yen-denominated balance sheet accounts are translated to U.S. dollars using the spot yen/dollar exchange rate at the end of the reporting period.

In recent periods, the Japanese yen has weakened against the U.S. dollar. Although the Company is unable to predict the timing or extent of future movements of the yen/dollar exchange rate, the Company maintains hedging strategies (see the Hedging Activities section of this MD&A) that are intended to mitigate the impacts of Japanese yen fluctuation on the Company’s financial position and results of operations. See the risk factor entitled “The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate” in Part I, Item 1A. Risk Factors for more information.

Income Taxes

The Company's combined U.S. and Japanese effective income tax rate on pretax earnings was 19.6% in 2025 and 15.2% in 2024. The combined effective tax rate differs from the U.S. statutory rate primarily due to the impact of tax credits from federal historic rehabilitation and solar investments in partnerships and the exclusion of foreign currency translation gains and losses on certain Aflac Japan U.S. dollar-denominated investments held in the Delaware Statutory Trust. Total income taxes were $887 million in 2025 and $974 million in 2024. Japanese income taxes on Aflac Japan's results account for most of the Company's consolidated income tax expense.

For additional information, see Note 10 of the Notes to the Consolidated Financial Statements and the Critical Accounting Estimates - Income Taxes section of this MD&A. The effective tax rate continues to be subject to future tax law changes both in the U.S. and in foreign jurisdictions. See the risk factor entitled "Tax rates applicable to the Company may change" in Part I, Item 1A. Risk Factors for additional information.

RESULTS OF OPERATIONS BY SEGMENT
U.S. GAAP financial reporting requires that a company report financial and descriptive information about operating segments in its annual and interim period financial statements. Furthermore, the Company is required to report a measure of segment profit or loss, certain revenue and expense items and segment assets. The Company's insurance business consists of two segments: Aflac Japan and Aflac U.S. Aflac Japan is the principal contributor to consolidated earnings. In addition, the Parent Company, other business units that are not individually reportable, reinsurance activities, including internal reinsurance activity with Aflac Re, and other business activities not included in Aflac Japan or Aflac U.S., as well as intercompany eliminations, are included in Corporate and other. See Item 1. Business for a summary of each segment's products and distribution channels.

Consistent with U.S. GAAP guidance for segment reporting, pretax adjusted earnings is the Company's U.S. GAAP measure of segment performance. The Company believes that a presentation of this measure is vitally important to an understanding of the underlying profitability drivers and trends of its business. Additional performance measures used to evaluate the financial condition and performance of the Company's segments are listed below.

•Operating Ratios
•New Annualized Premium Sales
•New Money Yield
•Return on Average Invested Assets
•Portfolio Book Yield
•Average Weekly Producer
•Premium Persistency

For additional information on the Company’s performance measures included in this MD&A, see the Glossary of Selected Terms found directly following Part IV. See Note 2 of the Notes to the Consolidated Financial Statements for the reconciliation of segment results to the Company's consolidated U.S. GAAP results and additional information.

In 2025, operating results in Japanese yen terms compared to the previous year were as follows:

•Net earned premiums decreased primarily due to approximately ¥21 billion related to the internal cancer reinsurance transaction with Aflac Re established in the fourth quarter of 2024 and approximately ¥15 billion from limited-pay products reaching premium paid-up status. Net earned premiums also reflect a remeasurement loss of approximately ¥8 billion related to assumption updates of the deferred profit liability for limited-payment contracts in the third quarter of 2025, compared to a remeasurement loss of approximately ¥11 billion in the third quarter of 2024.
•Adjusted net investment income decreased primarily due to lower floating rate income from U.S. dollar-denominated investments.


43
•Total adjusted revenues decreased primarily due to the decreases in net earned premiums and adjusted net investment income.
•Total benefits and claims decreased primarily due to ¥68 billion of reserve remeasurement gains related to assumption updates in the third quarter of 2025, compared to reserve remeasurement gains of approximately ¥50 billion in the third quarter of 2024, as well as the internal cancer reinsurance transaction with Aflac Re established in the fourth quarter of 2024.
•Total adjusted expenses increased primarily due to higher technology and sales-related expenses, partially offset by the impact of the internal cancer reinsurance transaction with Aflac Re established in the fourth quarter of 2024 and an increase in the capitalization of deferred policy acquisition costs resulting from higher sales.
•Pretax adjusted earnings decreased primarily due to the decrease in total adjusted revenues, partially offset by the decrease in total benefits and claims.

Annualized premiums in force at December 31, 2025 were ¥1.18 trillion, compared with ¥1.21 trillion at December 31, 2024. The decrease in annualized premiums in force in Japanese yen of 2.5% in 2025 and 3.0% in 2024 was driven primarily by limited-pay products reaching premium paid-up status. Annualized premiums in force, translated into U.S. dollars at respective year-end foreign exchange rates, were $7.5 billion at December 31, 2025, compared with $7.6 billion at December 31, 2024.

As of December 31, 2025, Aflac Japan exceeded 22 million individual policies in force in Japan, with approximately 14 million cancer policies in force in Japan.

Aflac Japan's investment portfolios include U.S. dollar-denominated securities and reverse dual-currency securities (Japanese yen-denominated fixed maturity securities with dollar coupon payments). In years when the Japanese yen strengthens in relation to the dollar, translating Aflac Japan's U.S. dollar-denominated investment income into Japanese yen lowers growth rates for net investment income, total adjusted revenues and pretax adjusted earnings in Japanese yen terms. In years when the Japanese yen weakens, translating U.S. dollar-denominated investment income into Japanese yen magnifies growth rates for net investment income, total adjusted revenues and pretax adjusted earnings in Japanese yen terms.

The following table illustrates the effect of translating Aflac Japan's U.S. dollar-denominated investment income and related items into Japanese yen by comparing certain segment results with those that would have been reported had foreign exchange rates remained unchanged from the prior year. Amounts excluding foreign currency impact on U.S. dollar-denominated investment income were determined using the average foreign exchange rate for the comparable prior year period. See non-U.S. GAAP financial measures defined above.

•In 2025, the total benefits and claims to total premiums ratio decreased primarily due to lower benefits resulting from assumption updates in the third quarter of 2025.
•The total adjusted expense ratio increased in 2025 primarily due to a year-over-year decrease in total adjusted revenues and an increase in total adjusted expenses.
•In total, the pretax adjusted profit margin increased in 2025 primarily due to the lower benefit ratio.

With continued cost pressure on Japan’s health care system, the Company expects the need for third sector products will continue to rise in the future and that the cancer and medical insurance products Aflac Japan provides will continue to be an important part of its product portfolio. Additionally, the Company believes that sales of first sector products, including Tsumitasu, WAYS and Child Endowment, position Aflac Japan for potential future long-term sales opportunities by marketing these products to a younger demographic as well as potential cross-selling opportunities of Aflac Japan's third sector products.

In 2025, Aflac Japan recruited 236 new sales agencies. At December 31, 2025, Aflac Japan was represented by approximately 6,300 sales agencies, with approximately 112,000 licensed sales associates employed by those agencies. The number of sales agencies has declined in recent years due to Aflac Japan's focus on supporting agencies with strong management frameworks, high productivity and more producing agents.

At December 31, 2025, Aflac Japan had agreements to sell its products at 358 banks, approximately 90% of the total number of banks in Japan.

Aflac Japan Investments

The level of investment income in Japanese yen is affected by available cash flow from operations, the timing of investing the cash flow, yields on new investments, the effect of yen/dollar exchange rates on U.S. dollar-denominated investment income and other factors.

As part of the Company's portfolio management and asset allocation process, Aflac Japan primarily invests in Japanese yen- and U.S. dollar-denominated investments. Aflac Japan's Japanese yen-denominated investments primarily consist of JGBs, public and private fixed maturity securities and equity securities. Aflac Japan's U.S. dollar-denominated investments include fixed maturity investments, loan receivables, and growth assets, including alternative investments in limited partnerships or similar investment vehicles.

In 2025, operating results compared to the previous year were as follows:

•Net earned premiums increased primarily due to improved sales.
•Adjusted net investment income decreased primarily due to lower floating rate income.
•Total adjusted revenues increased primarily due to the increase in net earned premiums, partially offset by the decrease in adjusted net investment income.
•Total benefits and claims increased primarily due to higher incurred claims, partially offset by $60 million of reserve remeasurement gains related to assumption updates in the third quarter of 2025, compared to reserve remeasurement gains of $11 million in the third quarter of 2024.
•Total adjusted expenses increased primarily due to a one-time technology-related expense and higher variable expenses associated with the growth in net earned premiums.
•Pretax adjusted earnings were essentially flat.

Annualized premiums in force increased 4.9% in 2025 and 3.6% in 2024. Annualized premiums in force at December 31, 2025 were $6.7 billion, compared with $6.4 billion at December 31, 2024.

(1) The change in value of federal historic rehabilitation and solar investments in partnerships of $65 and $165 in 2025 and 2024, respectively, is included as a reduction to net investment income. Tax credits on these investments of $69 and $164 in 2025 and 2024, respectively, have been reported as an income tax benefit in the consolidated statements of earnings. See Note 1 of the Notes to the Consolidated Financial Statements for additional information on these investments.

In 2025, operating results compared to the previous year were as follows:

•Net earned premiums and total benefits and claims increased primarily due to higher internal reinsurance activity resulting from the transaction established in the fourth quarter of 2024. The increase in total benefits and claims was partially offset by $31 million of reserve remeasurement gains related to assumption updates in the third quarter of 2025, compared to reserve remeasurement gains of $20 million in the third quarter of 2024.
•Adjusted net investment income increased primarily due to $100 million from a lower volume of federal historic rehabilitation and solar tax credit investments, with offsetting tax benefits recognized as a corresponding lower income tax expense, and higher Aflac Re investment income of $46 million from a higher volume of assets as part of the reinsurance agreement established in the fourth quarter of 2024.
•Total adjusted revenues increased primarily due to the increases in adjusted net investment income and net earned premiums.
•Total adjusted expenses increased primarily due to $61 million from higher costs pertaining to business operations, including costs related to the ongoing response to the cybersecurity incident and legal and other professional services related thereto, higher interest expense of $54 million, and $35 million associated with internal reinsurance activity.
•Pretax adjusted earnings increased primarily due to the increase in total adjusted revenues, partially offset by the increases in total adjusted expenses and total benefits and claims.



52
The Parent Company invests in partnerships that specialize in rehabilitating historic structures or the installation of solar equipment in order to receive federal historic rehabilitation and solar tax credits. These investments are classified as limited partnerships and included in other investments in the consolidated balance sheets. The change in value of each investment is reported as a reduction to net investment income. Tax credits generated by these investments are reported as an income tax benefit in the consolidated statements of earnings.

INVESTMENTS

The Company’s investment strategy utilizes disciplined asset and liability management while seeking long-term risk-adjusted investment returns and the delivery of stable income within regulatory and capital objectives, and preserving shareholder value. 

In attempting to optimally balance these objectives, the Company seeks to maintain on behalf of Aflac Japan a diversified portfolio of Japanese yen-denominated investment assets, a U.S. dollar-denominated investment portfolio hedged back to Japanese yen and a portfolio of unhedged U.S. dollar-denominated assets. As part of the Company's portfolio management and asset allocation process, Aflac U.S. invests in fixed maturity securities and growth assets, including equity securities and alternative investments in limited partnerships. Aflac U.S. invests in both publicly traded and privately originated investment-grade and below-investment-grade fixed maturity securities and loans.

The Company has invested in a variety of commercial mortgage loans (CMLs) and other loans including transitional real estate loans (TREs). The Company's TRE and CML investments are collateralized by commercial real estate, including some office properties. The Company considers these investments to be well diversified by geography and among property types. Further, the Company believes that the portfolio is generally well positioned with exposures concentrated in high quality underlying properties with institutional investors who are experienced in managing their assets during periods of market volatility.

While generally resilient, the Company's investments in TREs and CMLs have been affected by conditions in the commercial real estate market, with a greater impact on mortgages secured by office properties. The Company invested in certain TREs and CMLs that are currently in default of interest or maturity payments. The Company works with the affected borrowers to resolve specific situations through loan continuance with potential modifications, through loan sales, or through the process of foreclosure or deed in lieu of foreclosure. Since the third quarter of 2023, the Company has taken possession, through foreclosure or deed in lieu of foreclosure, of certain commercial real estate properties, which secured defaulted loans. Properties acquired by the Company through foreclosure and deed in lieu of foreclosure are reported as real estate owned (REO) in other investments in the Company's consolidated balance sheets.

In 2025, the Company completed foreclosure or deed in lieu of foreclosure on TREs collateralized with commercial real estate properties with an amortized cost of $257 million. As a result of the amortized cost of the TREs exceeding the estimated fair value of the collateral upon consummating the foreclosures or deed in lieu of foreclosure transactions, the Company recognized a net loss of $10 million in net investment gains (losses) for the year ended December 31, 2025.

In 2024, the Company completed foreclosure or deed in lieu of foreclosure on TREs collateralized with commercial real estate properties with an amortized cost of $502 million. As a result of the amortized cost of the TREs exceeding the estimated fair value of the collateral upon consummating the foreclosures or deed in lieu of foreclosure transactions, the Company recognized a net loss of $34 million in net investment gains (losses) for the year ended December 31, 2024.



54
The Company utilizes third-party asset managers to source, underwrite and manage each loan, as well as any resulting REO. The Company closely monitors the activities of these managers. In the event that a loan workout is necessary, the Company believes these external managers have the experience and resources to manage the process to maximize recovery.

The Company also monitors its commercial mortgage and other loan investments internally on an ongoing basis, including a review of loans' credit quality indicators and payment status as current, past due, restructured or under foreclosure. See Note 3 of the Notes to the Consolidated Financial Statements for further information concerning credit quality indicators, information on loans that are on nonaccrual status, and REO obtained through foreclosure or deed in lieu of foreclosure. See also Part I, Item 1A. Risk Factors for a discussion of risk factors associated with the Company's investments.

The ratings of the Company's securities referenced in the table below are based on the ratings designations provided by major rating organizations such as Moody's, Standard & Poor's and Fitch or, if not rated, are determined based on the Company's internal analysis of such securities. When the ratings issued by the rating agencies differ, the Company utilizes the second lowest rating when three or more rating agency ratings are available or the lowest rating when only two rating agency ratings are available.

The distributions of fixed maturity securities the Company owns, by credit rating, as of December 31 were as follows:

Generally, declines in fair values can be a result of changes in interest rates, yen/dollar exchange rate, and changes in net spreads driven by a broad market move or a change in the issuer's underlying credit quality. The Company believes these issuers have the ability to continue making timely payments of principal and interest.

The Company maintains an allocation to higher yielding corporate bonds within the Aflac Japan and Aflac U.S. portfolios. Most of these securities were rated below-investment-grade at the time of purchase, but the Company also purchased several that were rated investment grade which, because of market pricing, offer yields commensurate with below-investment-grade risk profiles. The objective of this allocation was to enhance the Company's yield on invested assets and further diversify credit risk. All investments in this program must have a minimum rating at purchase of low BB using the Company's above described rating methodology and are managed by the Company's internal credit portfolio management team.

The Company invests in middle market loans primarily to U.S. corporate borrowers, most of which have below-investment-grade ratings. The objectives of this program include enhancing the yield on invested assets, achieving further diversification of credit risk, and mitigating the risk of rising interest rates and hedge costs through the acquisition of floating rate assets.

Fixed Maturity Securities by Sector

The Company maintains diversification in investments by sector to avoid concentrations to any one sector, thus managing exposure risk. The following table shows the distribution of fixed maturities by sector classification as of December 31.

Securities by Type of Issuance
The Company has investments in both publicly and privately issued securities. The Company's ability to sell either type of security is a function of overall market liquidity which is impacted by, among other things, the amount of outstanding securities of a particular issuer or issuance, trading history of the issue or issuer, overall market conditions, and idiosyncratic events affecting the specific issue or issuer.

(1) Principal payments in Japanese yen and interest payments in U.S. dollars

Aflac Japan has a portfolio of privately issued securities to better match liability characteristics and secure higher yields than those available on Japanese government or other public corporate bonds. Aflac Japan’s investments in Japanese yen-denominated privately issued securities consist primarily of non-Japanese issuers, are rated investment grade at purchase and have longer maturities, thereby allowing the Company to improve asset/liability matching and overall investment returns. These securities are generally either privately negotiated arrangements or issued under medium-term note programs and have standard documentation commensurate with credit ratings of the issuer, except when internal credit analysis indicates that additional protective and/or event-risk covenants were required. Many of these investments have protective covenants appropriate to the specific investment. These may include a prohibition of certain activities by the borrower, maintenance of certain financial measures, and specific conditions impacting the payment of the Company's notes.

HEDGING ACTIVITIES

The Company uses derivative contracts to hedge foreign currency exchange risk and interest rate risk. The Company uses various strategies, including derivatives, to manage these risks. See Item 7A. Quantitative and Qualitative Disclosures About Market Risk for additional information about market risk and the Company’s use of derivatives.

See Note 4 of the Notes to the Consolidated Financial Statements for:

•A description of the Company's derivatives, hedging strategies and underlying risk exposure.
•Information about the notional amount and fair market value of the Company's derivatives.
•Impact on earnings and other comprehensive income (loss) from various qualifying and non-qualifying hedging relationships.



58
Foreign Currency Exchange Risk Hedge Program

The Company has deployed the following hedging strategies to mitigate exposure to foreign currency exchange risk:
•Aflac Japan hedges U.S. dollar-denominated investments back to Japanese yen (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).
•Aflac Japan maintains certain unhedged U.S. dollar-denominated securities, which serve as an economic currency hedge of a portion of the Company's investment in Aflac Japan, while utilizing foreign currency options to mitigate against significant movements in the yen/dollar exchange rate (see Aflac Japan’s U.S. Dollar-Denominated Hedge Program below).
•Aflac Japan economically hedges the foreign currency exchange risk on certain of its investments that are denominated in other foreign currencies.
•The Parent Company designates Japanese yen-denominated liabilities (notes payable and loans) as non-derivative hedging instruments and designates certain foreign currency forwards and options as derivative hedges of the Company’s net investment in Aflac Japan (see Enterprise Corporate Hedging Program below).
•The Parent Company enters into forward and option contracts to protect the value of Aflac Japan in U.S. dollar terms by hedging foreign currency exchange risk related to dividend payments by Aflac Japan and reduce enterprise-wide hedge costs (see Enterprise Corporate Hedging Program below).

The following table presents metrics related to the Company's Foreign Currency Exchange Risk Hedge Program, including associated amortized hedge costs/income, for the years ended December 31. See the Results of Operations section of this MD&A for the Company's definition of amortized hedge costs/income.

Amortized hedge costs/income can fluctuate based upon many factors, including the derivative notional amount, the length of time of the derivative contract, changes in both U.S. and Japan interest rates, and the cross-currency basis. Amortized hedge costs/income have fluctuated in recent periods due to changes in the previously mentioned factors.

Aflac Japan’s U.S. Dollar-Denominated Hedge Program (U.S. Dollar Program)

Aflac Japan buys U.S. dollar-denominated investments, typically corporate bonds, and hedges them back to Japanese yen with foreign currency forwards and options to hedge foreign currency exchange risk. This economically creates Japanese yen assets that match Japanese yen liabilities during the life of the derivative and provides favorable capital treatment under the Japan SMR calculations. The currency risk being hedged is generally based on fair value of hedged investments. The following table summarizes the U.S. dollar-denominated investments held by Aflac Japan as of December 31.

(1) Net of allowance for credit losses

The U.S. Dollar Program includes all U.S. dollar-denominated investments held by Aflac Japan other than the investments in certain consolidated VIEs where the instrument is economically converted to Japanese yen as a result of a derivative in the consolidated VIE. The Company uses foreign currency forwards to hedge foreign currency exchange risk on certain U.S. dollar-denominated investments held by Aflac Japan and one-sided foreign currency put options to mitigate the risk of a decline in the value of U.S. dollar-denominated assets (in Japanese yen terms) related to extreme foreign exchange rate changes. From time to time, Aflac Japan also maintains a collar program on a portion of its U.S. Dollar Program to mitigate against more extreme moves in foreign exchange rates and therefore support SMR. As of December 31, 2025, none of the Company's foreign currency options hedging Aflac Japan's U.S. dollar-denominated assets were in-the-money.

Foreign currency derivatives used for hedging are periodically settled, which results in cash receipt or payment at inception, maturity or early termination. The following table presents the settlements associated with the Company's foreign currency derivatives used for hedging Aflac Japan’s U.S. dollar-denominated investments for the years ended December 31.
(In millions)20252024
Net cash inflows (outflows)$(71)$(508)

In addition to the U.S. dollar Program, Aflac Japan utilizes foreign currency forwards to economically hedge the foreign currency exchange risk on certain of its variable-rate investments denominated in other foreign currencies. As of December 31, 2025, the Company had foreign currency forwards on other foreign currency-denominated investments with a fair value of $135 million.

Aflac Japan also utilizes foreign currency swaps to economically hedge the foreign currency exchange risk on certain of its fixed maturity securities denominated in other foreign currencies. As of December 31, 2025, the Company had foreign currency swaps on other foreign currency-denominated investments with a fair value of $48 million.

Enterprise Corporate Hedging Program

The Company has designated certain Japanese yen-denominated liabilities and foreign currency forwards and options of the Parent Company as accounting hedges of its net investment in Aflac Japan. The Company's consolidated Japanese yen-denominated net asset position was partially hedged at $6.8 billion as of December 31, 2025, with hedging instruments comprised of $5.0 billion of Japanese yen-denominated debt and $1.8 billion of foreign currency forwards, compared with $5.9 billion as of December 31, 2024, with hedging instruments comprised of $4.1 billion of Japanese yen-denominated debt and $1.8 billion of foreign currency forwards.

The Company makes its accounting designation of net investment hedge at the beginning of each quarter. If the total of the designated Parent Company non-derivative and derivative notional is equal to or less than the Company's net investment in Aflac Japan, the hedge is deemed to be effective, and the foreign currency exchange effect on the


60
Japanese yen-denominated liabilities and the change in estimated fair value of the derivatives are included in unrealized foreign currency translation gains (losses) in the consolidated statements of comprehensive income (loss). The Company's net investment hedge was effective during the years ended December 31, 2025 and 2024, respectively. For additional information on the Company's net investment hedging strategy, see Note 4 of the Notes to the Consolidated Financial Statements.

In order to economically mitigate risks associated with the enterprise-wide exposure to the Japanese yen and the level and volatility of hedge costs, the Parent Company enters into foreign currency forward and option contracts. By buying U.S. dollars and selling Japanese yen, the Parent Company is effectively lowering its overall economic exposure to the Japanese yen. In addition to reducing Japanese yen exposure from dividend payments by Aflac Japan to the Parent Company, this strategy also reduces enterprise-wide hedge costs. This activity is reported in Corporate and other. The Company continually evaluates the program’s efficacy.

As part of the Company’s internal reinsurance platform, Aflac Re enters into foreign currency forwards with the Parent Company, and may enter into such forwards with third parties, to economically manage the currency mismatch between Aflac Re's assets, which are mostly denominated in U.S. dollars, and liabilities, which are mostly denominated in Japanese yen, in order to support and optimize BMA capital requirements. For additional information on the Company's internal reinsurance platform, see Note 8 of the Notes to the Consolidated Financial Statements and the Liquidity and Capital Resources section of this MD&A.

For additional discussion of the risks associated with the foreign currency exposure refer to the Currency Risk section in Item 7A. Quantitative and Qualitative Disclosures about Market Risk, and Item 1A. specifically to the Risk Factors titled “The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate“ and “Lack of availability of acceptable Japanese yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity."

Interest Rate Risk Hedge Program

Aflac Japan and Aflac U.S. use interest rate swaps from time to time to mitigate the risk of investment income volatility for certain variable-rate investments. Additionally, to manage interest rate risk associated with its U.S. dollar-denominated investments held by Aflac Japan, from time to time the Company utilizes interest rate swaptions.

See Note 4 of the Notes to the Consolidated Financial Statements for additional information on the Company's hedging activities.

BENEFIT PLANS

Aflac Japan and Aflac U.S. have various benefit plans. For additional information on the Company's Japanese and U.S. plans, see Note 13 of the Notes to the Consolidated Financial Statements.

POLICYHOLDER PROTECTION
Policyholder Protection Corporation

The Japanese insurance industry has a policyholder protection system that provides funds for the policyholders of insolvent insurers. Legislation enacted regarding the framework of the Life Insurance Policyholder Protection Corporation (LIPPC) included government fiscal measures supporting the LIPPC. In March 2022, Japan's Diet passed legislation that extended the government's fiscal support of the LIPPC through March 2027. In March 2022, the LIPPC reached the required balance for the total life industry of ¥400 billion as specified by its Articles of Incorporation. As a result, additional contributions are not expected to be required unless the balance is reduced due to payments made by the LIPPC to the policyholders of insolvent insurers. Accordingly, Aflac Japan did not recognize an expense for LIPPC assessments for the years ended December 31, 2025 and 2024.

Guaranty Fund Assessments

Under U.S. state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business. The amount of the guaranty fund assessment that an insurer is assessed is based on its proportionate share of premiums in that state. See Note 15 of the Notes to the Consolidated Financial Statements for additional information on guaranty fund assessments. Guaranty fund assessments for the years ended December 31, 2025 and 2024 were immaterial.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity refers to the ability to generate sufficient cash resources to meet the payment obligations of the Company. Capital refers to the long-term financial resources available to support the operations of the businesses, fund business growth and provide for an ability to withstand adverse circumstances. Financial leverage (leverage) refers to a strategy of utilizing debt in managing the Company's capital structure and cost of capital. The Company targets and actively manages liquidity, capital and leverage in the context of a number of considerations, including:

•business investment and growth needs
•strategic growth objectives
•financial flexibility and obligations
•capital support for hedging activity
•a constantly evolving business and economic environment
•a balanced approach to capital allocation and deployment to shareholders

The governance framework supporting liquidity, capital, and leverage includes global senior management and board committees that review and approve all significant capital related decisions.

The Company remains committed to prudent liquidity and capital management. To provide a capital buffer and liquidity support at the holding company, the target minimum amount for the Parent Company is approximately $1.0 billion.

Aflac Japan and Aflac U.S. generate cash flows from their operations and provide the primary sources of liquidity to the Parent Company through management fees and dividends, with Aflac Japan being the largest contributor. The primary uses of cash by the Parent Company are shareholder dividends, the repurchase of its common stock, interest on its outstanding indebtedness and operating expenses.

Aflac Japan dividends declared or paid to Parent Company (in yen)¥396.7 ¥441.6 

The Company maintains liquidity at the Parent Company for risk management purposes and to support certain derivative activity. Further, the Company plans to continue to maintain a population of unhedged U.S. dollar-denominated investments held by Aflac Japan and to consider whether the amount of such investments should be increased or decreased relative to the Company’s view of economic equity surplus in Aflac Japan in light of potentially rising hedge costs and other factors. See the Hedging Activities subsection of this MD&A for additional information.

The Company believes that its balance of cash and cash equivalents and cash generated by operations will be sufficient to satisfy both its short-term and long-term cash requirements and plans for cash, including material cash requirements from known contractual obligations and returning capital to shareholders through share repurchases and dividends.

In addition to cash and cash equivalents, the Company also maintains credit facilities, both intercompany and with external partners, and a number of other available tools to support liquidity needs on a global basis. In September 2024, the Parent Company filed a shelf registration statement with the SEC that allows the Company to issue an indefinite amount of debt securities, in one or more series, from time to time until September 2027. The Company believes outside sources for additional debt and equity capital, if needed, will continue to be available. The Company was in compliance with all of the covenants of its notes payable and lines of credit at December 31, 2025.

In August 2025, the Parent Company expanded its sources of liquidity by entering into two separate facility agreements, as follows:
1.A 10-year facility agreement with a Delaware trust (2035 Trust) that provides the Parent Company with the right to issue and sell to the 2035 Trust from time to time up to $1.0 billion of senior notes due August 2035.
2.A 30-year facility agreement with a Delaware trust (2055 Trust) that provides the Parent Company the right to issue and sell to the 2055 Trust from time to time up to $1.0 billion of senior notes due August 2055.

As of December 31, 2025, the Parent Company had no senior note issuances under these facility agreements.

For additional information, see Note 9 of the Notes to the Consolidated Financial Statements.

As part of enterprise-wide capital management and optimization, the Company also utilizes the intercompany reinsurance platform to execute internal reinsurance transactions with Aflac Re. For additional information, see Note 8 of the Notes to the Consolidated Financial Statements.

(2) The estimated payments reflect future estimated cash payments to be made to policyholders and others for future policy benefits and certain related expenses using assumptions aligned with the Company's experience on policy persistency, mortality, morbidity and other assumptions. These cash outflows are undiscounted with respect to interest, and future premium payments received from policyholders are not included. Therefore, the sum of the cash outflows exceeds the corresponding liability amount. Due to the significance of the assumptions used, actual cash outflow amounts and timing will differ, possibly materially, from these estimates.
(3) These cash outflows are undiscounted with respect to interest and, as a result, the sum of the cash outflows exceeds the corresponding liability amount.

For additional information on the Company's major contractual obligations, see the applicable Note in the Notes to the Consolidated Financial Statements as indicated in the line items in the table above.

The Company's consolidated financial statements convey its financing arrangements during the periods presented. The Company has not engaged in material intra-period short-term financings during the periods presented that are not otherwise reported in its balance sheet or disclosed therein. As of December 31, 2025, the Company had no material letters of credit, standby letters of credit, guarantees or standby repurchase obligations. The Company has not entered into transactions involving the transfer of financial assets with an obligation to repurchase financial assets that have been accounted for as a sale under applicable accounting standards, including securities lending transactions. See Notes 1, 3, and 4 of the Notes to the Consolidated Financial Statements for additional information on the Company's securities lending and derivative activities. With the exception of disclosed activities in those referenced footnotes and the Risk Factors entitled, "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" and "Lack of availability of acceptable Japanese yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity," the Company is not aware of any trend, demand, commitment, event or uncertainty that would reasonably result in its liquidity increasing or decreasing by a material amount.
Consolidated Cash Flows

The Company consistently generates positive cash flows from operations, and has the ability to adjust cash flow management from other sources of liquidity including reinvestment cash flows and selling investments in order to meet short-term cash needs.

The Company translates cash flows for Aflac Japan's yen-denominated items into U.S. dollars using weighted-average foreign exchange rates. In years when the Japanese yen weakens, translating Japanese yen into U.S. dollars causes fewer U.S. dollars to be reported. When the Japanese yen strengthens, translating Japanese yen into U.S. dollars causes more U.S. dollars to be reported.

Operating Activities

The principal cash inflows for the Company's insurance activities come from insurance premiums and investment income. The principal cash outflows are the result of policy claims, operating expenses, income tax, as well as interest expense. As a result of policyholder aging, claims payments are expected to gradually increase over the life of a policy. Therefore, future policy benefit reserves are accumulated in the early years of a policy and are designed to help fund future claims payments.

The Company expects its future cash flows from premiums and investment portfolios to be sufficient to meet its cash needs for benefits and expenses. Consolidated cash flow from operations decreased 5.6% in 2025, compared with 2024.

Investing Activities

The Company's investment objectives provide for liquidity primarily through the purchase of publicly traded investment-grade fixed maturity securities. Prudent portfolio management dictates that the Company attempts to match the duration of its assets with the duration of its liabilities. Currently, when the Company's fixed maturity securities mature, the proceeds may be reinvested at a yield below that required for the accretion of policy benefit liabilities on policies issued in earlier years. However, the long-term nature of the Company's business and its strong cash flows provide the Company with the ability to minimize the effect of mismatched durations and/or yields identified by various asset adequacy analyses. From time to time or when market opportunities arise, the Company disposes of selected fixed maturity securities that are available-for-sale to improve the duration matching of assets and liabilities, improve future investment yields, and/or rebalance its portfolio. As a result, dispositions before maturity can vary significantly from year to year.

As part of its overall corporate strategy, the Company has committed up to $400 million to Aflac Ventures, LLC (Aflac Ventures), as opportunities emerge. As of December 31, 2025, of the $400 million committed, approximately $297 million has been deployed. Aflac Ventures is a subsidiary of Aflac Global Ventures, LLC (Aflac Global Ventures) which is reported in Corporate and other. The central mission of Aflac Global Ventures is to support the organic growth and business development needs of Aflac Japan and Aflac U.S. with an emphasis on digital applications designed to improve the customer experience, gain efficiencies, and develop new markets in an effort to enhance and defend long-term shareholder value. Investments are included in equity securities or other investments in the consolidated balance sheets.

As part of an arrangement with Federal Home Loan Bank of Atlanta (FHLB), Aflac U.S. obtains low-cost investment funding from FHLB supported by acceptable forms of collateral pledged by Aflac U.S. In 2025, Aflac U.S. borrowed and repaid $777 million under this program. As of December 31, 2025, Aflac U.S. had outstanding borrowings of $334 million reported in its balance sheet.

Regulatory Restrictions

Aflac Japan

Aflac Japan is required to meet certain financial criteria as governed by the Companies Act of Japan in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at Aflac Japan is defined as total equity excluding common stock and capital reserves but reduced for net after-tax unrealized losses on available-for-sale securities. These dividend capacity requirements are generally aligned with the SMR. Japan's FSA maintains its own solvency standard which is quantified through the SMR. Aflac Japan's SMR is sensitive to interest rate, credit spread, and foreign exchange rate changes; therefore, the Company continues to evaluate alternatives for reducing this sensitivity, including the reduction of subsidiary dividends paid to the Parent Company and Parent Company capital contributions. In the event of a rapid change in market risk conditions causing SMR to decline, or in the event of reduced liquidity, the Company has a senior unsecured revolving credit facility in the amount of ¥100 billion as a contingency plan. See Note 9 of the Notes to the Consolidated Financial Statements for additional information. Additionally, subject to market conditions, the Company expects that it could take action to enter into derivatives on unhedged U.S. dollar-denominated investments with foreign currency options or forwards or execute additional reinsurance transactions.



66
The Company has already undertaken various measures to mitigate the sensitivity of Aflac Japan's SMR. For example, the Company employs policy reserve matching (PRM) investment strategies, which is a Japan-specific accounting treatment that reduces SMR interest rate sensitivity since PRM-designated investments are carried at amortized cost consistent with corresponding liabilities. In order for a PRM-designated asset to be held at amortized cost, there are certain criteria that must be maintained. The primary criterion relates to maintaining the duration of designated assets and liabilities within a specified tolerance range. If the duration difference is not maintained within the specified range without rebalancing, then a certain portion of the assets must be reclassified as available-for-sale and held at fair value with any associated unrealized gain or loss recorded in surplus. To rebalance, assets may need to be sold in order to maintain the duration with the specified range, resulting in realizing a gain or loss from the sale. For U.S. GAAP, PRM investments are categorized as available-for-sale. The Company also uses foreign currency derivatives to hedge a portion of its U.S. dollar-denominated investments. See Notes 3, 4 and 8 of the Notes to the Consolidated Financial Statements for additional information on the Company's investment strategies, hedging activities, and reinsurance, respectively.

Aflac Japan's SMR remains high and reflects a strong capital and surplus position. As of December 31, 2025, Aflac Japan's SMR was 995%, compared with 1,221% at December 31, 2024. The Company is committed to maintaining strong capital levels, consistent with maintaining current insurance financial strength and credit ratings.

The FSA will implement an economic value-based solvency regime based on the ICS for insurance companies in Japan. The initial report on the ESR will be issued as of March 31, 2026, which is Aflac Japan's 2025 fiscal year-end. As of December 31, 2025, Aflac Japan estimated the ESR to be above the Company's target range of 170% to 230%.

Aflac U.S.

A life insurance company’s statutory capital and surplus is determined according to rules prescribed by the NAIC, as modified by the insurance department in the insurance company’s state of domicile. Statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency. The continued long-term growth of the Company's business may require increases in the statutory capital and surplus of its insurance operations. The Company's insurance operations may secure additional statutory capital through various sources, such as internally generated statutory earnings, reduced dividends paid to the Parent Company, capital contributions by the Parent Company from funds generated through debt or equity offerings, or reinsurance transactions. The NAIC’s RBC formula is used by insurance regulators to help identify inadequately capitalized insurance companies. The RBC formula quantifies insurance risk, business risk, asset risk and interest rate risk by weighing the types and mixtures of risks inherent in the insurer’s operations.

The combined RBC ratio for Aflac U.S. as of December 31, 2025 was estimated to be 570%, compared with 677% as of December 31, 2024. The Company calculates its combined RBC ratio to include all U.S. regulated life insurance entities as if a single combined U.S. RBC entity net of intercompany items related to capital resources and risk.

Aflac, CAIC and TOIC are domiciled in Nebraska and are subject to its regulations. The NDOI imposes certain limitations and restrictions on payments of dividends, management fees, loans and advances to the Parent Company. Under Nebraska insurance law, prior approval of the NDOI is required for dividend distributions that exceed the greater of the net income from operations, which excludes net investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. Dividends declared by Aflac during 2026 in excess of $664 million would be considered extraordinary and require such approval. Similar laws apply in New York, the domiciliary jurisdiction of Aflac New York.



67
Corporate and Other

Aflac Re is licensed by the BMA as a long-term insurer and is subject to the Bermuda Insurance Act of 1978 (Bermuda Insurance Act). Aflac Re is required to file annual and quarterly returns for its Bermuda Solvency Capital Requirement (BSCR) which utilizes an Economic Balance Sheet (EBS) framework to determine Aflac Re’s Enhanced Capital Requirement (ECR). Aflac Re is also subject to a Minimum Margin of Solvency (MSM) related to its statutory financial statements. The MSM is equal to the greater of $8,000,000; 2% of the first $500,000,000 of assets under management plus 1.5% of the amount by which assets exceed $500,000,000; or 25% of ECR.

Under the EBS framework, Aflac Re is required to value assets equal to U.S. GAAP fair values, and insurance reserves are valued using technical provisions which consist of a best estimate liability plus a risk margin. The best estimate liability can be calculated by applying the standard approach or, with regulatory approval, the scenario-based approach. The standard approach uses discount rates for insurance reserves as prescribed by the BMA. The scenario-based approach uses a discount rate based on the yield of eligible assets owned by the insurer as determined using a series of prescribed stress scenarios. At December 31, 2025 and 2024, Aflac Re was in compliance with the ECR and MSM requirements.

Under the Bermuda Insurance Act, Aflac Re is prohibited from paying dividends in an amount that exceeds 25% of the prior year's statutory capital and surplus without an affidavit stating that Aflac Re will continue to meet its solvency margin. Further, Aflac Re may not reduce its total statutory capital by 15% or more without prior regulatory approval. Additionally, Aflac Re is not permitted to pay any dividends that would cause Aflac Re to fail to meet its minimum capital requirements.

CRITICAL ACCOUNTING ESTIMATES

The Company prepares its financial statements in accordance with U.S. GAAP. These principles are established primarily by the FASB. In this MD&A, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards Codification™ (ASC). The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The estimates that the Company deems to be most critical to an understanding of its results of operations and financial condition are those related to the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits (LFPB), and income taxes. The preparation and evaluation of these critical accounting estimates involve the use of various assumptions developed from management’s analyses and judgments. Calculations of DAC and the LFPB require the use of estimates based on actuarial valuation techniques. The application of these critical accounting estimates determines the values at which 92% of the Company's assets and 74% of its liabilities are reported as of December 31, 2025, and thus has a direct effect on net earnings and shareholders' equity. Subsequent experience or use of other assumptions could produce significantly different results.



68
Valuation of Investments, Including Derivatives

The Company's investments, primarily consisting of fixed maturity and equity securities, include both publicly issued and privately issued securities. For publicly issued securities, the Company determines the fair values from quoted market prices readily available from public exchange markets and price quotes and valuations from third-party pricing vendors. For the majority of privately issued securities and derivatives associated with VIEs within the Company's investment portfolio, the Company utilizes valuation models developed by a third-party pricing vendor to determine fair values. These models and associated processes and controls are executed by Company personnel. For the remaining privately issued securities, the Company uses non-binding price quotes from outside brokers and fair values provided by its external managers. The Company's valuation model for private placements explicitly incorporates currency basis swap adjustments (market observable data) to assumed interest rate curves where appropriate.

The Company estimates the fair values of its securities on a monthly basis. The Company monitors the estimated fair values obtained from its pricing vendors, external managers, and brokers for consistency from month to month, while considering current market conditions. The Company also periodically discusses with its pricing brokers and vendors the pricing techniques they use to monitor the consistency of their approach and to periodically assess the appropriateness of the valuation level assigned to the values obtained from them. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the provider. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data and information. The Company has performed verification of the inputs and calculations in any valuation models to confirm that the valuations represent reasonable estimates of fair value. Inputs used to value derivatives include, but are not limited to, interest rates, credit spreads, foreign currency forward and spot rates, foreign currency volatility, and interest rate volatility.

The Company estimates an allowance for credit losses on investments measured at amortized cost including held-to-maturity securities, loan receivables and certain loan commitments on a quarterly basis. For collateral dependent financial assets, including loans where foreclosure is probable, the allowance for credit losses is based on the fair value of the underlying collateral. For the Company’s available-for-sale securities, the Company evaluates an estimate for credit losses only when the fair value of the available-for-sale security is below its amortized cost basis.

The Company’s approach to estimating an allowance for credit losses is complex and incorporates significant judgments. In addition to a security, an asset class, or issuer-specific credit fundamentals, it considers past events, current economic conditions and forecasts of future economic conditions. The Company's estimates are revised as conditions change and new information becomes available.

For additional information, see the tabular disclosure entitled "Sensitivity of Fair Values of Financial Instruments to Interest Rate Change" in Item 7A. Quantitative and Qualitative Disclosures About Market Risk and Notes 1, 3, 4 and 5 of the Notes to the Consolidated Financial Statements.

Deferred Policy Acquisition Costs and Future Policy Benefits

Substantially all of the supplemental health and life insurance policies the Company issues are classified as long-duration contracts. The contract provisions generally cannot be changed or canceled during the contract period. However, the Company may adjust premiums for supplemental health policies issued in the U.S. within prescribed guidelines and with the approval of state insurance regulatory authorities.

Insurance premiums for most of the Company's health and life insurance policies are recognized as earned premiums over the premium-paying periods of the contracts when due from policyholders. When earned premiums are reported, the related amounts of benefits and expenses are charged against such revenues. This association is accomplished by means of annual increases or decreases to the LFPB and the deferral and subsequent amortization of policy acquisition costs.

Premiums from the Company's products with limited-pay features are collected over a significantly shorter period than the contract term (i.e., the period during which benefits are provided). Premiums for these products are recognized as earned premiums over the premium-paying periods when due from policyholders. Any gross premium in excess of the net premium is deferred and reported as a deferred profit liability, a component of the LFPB, which is subsequently amortized in net earned premiums such that profits are recognized in a constant relationship with insurance in force. Benefits are recorded as an expense when they are incurred and LFPB is recorded when premiums are recognized using the net premium method.


69

Deferred Policy Acquisition Costs

Amortization of DAC is computed using the same contract groupings (also referred to as cohorts) and mortality and termination assumptions that are used in computing the LFPB. These assumptions are reviewed and updated at least annually. The effects of changes in assumptions are recognized prospectively over the remaining contract term as a revision of the future amortization pattern, while current period amortization is calculated based on the actual experience during the quarter. For additional information, see Notes 1 and 6 of the Notes to the Consolidated Financial Statements.

Future Policy Benefits

The Company's LFPB is determined in accordance with applicable guidelines as defined under U.S. GAAP and Actuarial Standards of Practice and represent claims that are expected to occur in the future and incurred claims. Incurred claims represent claims in the process of payment as well as an estimate of those claims that have been incurred but have not yet been reported to the Company. LFPB is determined using the net level premium method. The LFPB is calculated using assumptions and estimates including, (1) cash flow assumptions (mortality, morbidity, and termination, also referred to as lapses), (2) expense assumptions, and (3) discount rates. The assumptions and estimates that the Company uses depend on its judgment regarding the likelihood of future events and are inherently uncertain.

Cash flow assumptions are established at policy inception and are evaluated each quarter to determine if an update is needed. Actual experience is reflected in the calculation of future policy benefits each quarter, and changes in the liability due to actual experience are included in reserve remeasurement (gains) losses in the consolidated statements of earnings.

To facilitate a more detailed review of cash flow assumptions, experience studies are performed annually during the third quarter. Changes in cash flow assumptions are the result of applying the updated best estimate assumptions as of the beginning of the reporting period and are included as a cumulative catch-up adjustment in reserve remeasurement (gains) losses in the consolidated statements of earnings.

Expense assumptions are established at policy inception, determined for each issue-year cohort as a percentage of paid claims. These expense assumptions are locked in and remain unchanged over the term of the insurance policy.

Discount rates used to calculate net premiums are locked in at policy inception and represent the basis to recognize interest expense accreted on insurance reserves included in benefits and claims, excluding reserve remeasurement in the consolidated statements of earnings. These locked-in discount rates are determined separately for each issue-year cohort as a single discount rate that reflects the duration characteristics of the corresponding insurance contracts and will remain unchanged after the calendar year of issue.

Discount rates used to measure the carrying value of the LFPB in the consolidated balance sheets are updated each reporting period, and the differences between the liability balances calculated using the locked-in discount rates and the updated discount rates is included in the effect of changes in discount rate assumptions in accumulated other comprehensive income (loss).

The Company's discount rate methodology involves constructing a current discount rate curve separately for discounting cash flows used to calculate the Japan and U.S. LFPB. This methodology is designed to prioritize observable inputs based on market data available in the local debt markets where the respective policies were issued in the currency in which the policies are denominated. For the discount rates applicable to tenors for which the single-A debt market is not liquid or there is little or no observable market data, the Company uses various estimation techniques consistent with the fair value guidance in ASC 820 - Fair Value Measurement, which include, but are not limited to: (i) for tenors where there is less observable market data and/or the observable market data is available for similar instruments, estimating tenor-specific single-A credit spreads and applying them to risk-free government rates; (ii) for tenors where there is very limited or no observable single-A or similar market data, interpolation and extrapolation techniques.

If interest rates decreased by 100 basis points, the Company's LFPB balance as of December 31, 2025 would increase by $7.4 billion, assuming all other factors remain constant. Likewise, if interest rates increased by 100 basis points, the Company's LFPB balance as of December 31, 2025 would decrease by $5.9 billion, assuming all other factors remain constant.



70
If morbidity assumptions decreased by 100 basis points, the Company's LFPB balance as of December 31, 2025 would decrease by $299 million, assuming all other factors remain constant. Likewise, if morbidity assumptions increased by 100 basis points, the Company's LFPB balance as of December 31, 2025 would increase by $303 million, assuming all other factors remain constant.

For additional information on future policy benefits, see Notes 1 and 7 of the Notes to the Consolidated Financial Statements.

Income Taxes

Income tax provisions are generally based on pretax earnings reported for financial statement purposes, which differ from those amounts used in preparing the Company's income tax returns. Deferred income taxes are recognized for temporary differences between the financial reporting basis and income tax basis of assets and liabilities, based on enacted tax laws and statutory tax rates applicable to the periods in which the Company expects the temporary differences to reverse. The evaluation of a tax position in accordance with U.S. GAAP is a two-step process. Under the first step, the enterprise determines whether it is more likely than not that a tax position will be sustained upon examination by taxing authorities. The second step is measurement, whereby a tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized. The determination of a valuation allowance for deferred tax assets requires management to make certain judgments and assumptions.

In evaluating the ability to recover deferred tax assets, the Company's management considers all available evidence, including taxable income in open carry back years, the existence of cumulative losses in the most recent years, forecasted earnings, future taxable income exclusive of reversing temporary differences and carryforwards, future taxable temporary difference reversals, and prudent and feasible tax planning strategies. In the event the Company determines it is not more likely than not that it will be able to realize all or part of its deferred tax assets in the future, a valuation allowance would be charged to earnings in the period such determination is made. Likewise, if it is later determined that it is more likely than not that those deferred tax assets would be realized, the previously provided valuation allowance would be reversed. Future economic conditions and market volatility, including increases in interest rates or widening credit spreads, can adversely impact the Company’s tax planning strategies and in particular the Company’s ability to utilize tax benefits on previously recognized capital losses. The Company's judgments and assumptions are subject to change given the inherent uncertainty in predicting future performance and specific industry and investment market conditions.

An increase or decrease in the Company's effective tax rate by one percentage point would have resulted in an increase or decrease in the Company's 2025 income tax expense of $50 million.

For additional information on income taxes, see Note 10 of the Notes to the Consolidated Financial Statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The Company is exposed primarily to the following types of market risks: currency risk, interest rate risk, credit risk and equity risk. Fluctuations in these factors could impact the Company’s consolidated results of operations or financial condition. The Company regularly monitors its market risks and uses a variety of strategies to manage its exposure to these market risks.

Currency Risk

Aflac Japan

The functional currency of Aflac Japan's insurance operations is the Japanese yen. Aflac Japan’s premiums and a significant portion of its investment income are received in Japanese yen, and its claims and most expenses are paid in Japanese yen. Aflac Japan purchases Japanese yen-denominated assets and U.S. dollar-denominated assets, which may be hedged to Japanese yen, to support Japanese yen-denominated policy liabilities. These and other Japanese yen-denominated financial statement items are, however, translated into U.S. dollars for financial reporting purposes. Most of Aflac Japan's cash and liabilities are Japanese yen-denominated.


71

The Company engages in hedging activities to mitigate certain currency risks from holding U.S. dollar-denominated investments in Aflac Japan; however, this hedging program also has some inherent risks. There is a risk that in a scenario of long-term Japanese yen weakening there could be significant derivative losses that create corresponding liquidity requirements to support interim derivative settlements. Further, the derivatives used for hedging are shorter in duration than the hedged investments, so there is rollover risk. In unfavorable market environments, the rollover of derivatives throughout the hedging period could result in increased hedge costs. Additionally, as discussed in detail in the Risk Factors section titled “Lack of availability of acceptable Japanese yen-denominated investments could adversely affect the Company's results of operations, financial position or liquidity,” there is a risk that losses realized on derivative settlements during periods of Japanese yen weakening may not be recouped through realization of the corresponding holding currency gains on the hedged U.S. dollar-denominated investments if these investments are not ultimately sold and the U.S. dollar proceeds converted to Japanese yen.

The Company has taken steps to refine the strategy to mitigate currency exposure of Aflac Japan from U.S. dollar-denominated investments while balancing the consideration of the economic equity surplus in Aflac Japan. This refinement in strategy resulted in an increased amount of the unhedged U.S. dollar-denominated investments held in Aflac Japan while at the same time mitigating hedge cost increases. Generally, Aflac Japan’s exposure to the currency risk increases when its portfolio of unhedged U.S. dollar-denominated investments increases. As the value of the U.S. dollar-denominated investment portfolio in Aflac Japan fluctuates and the Company’s business model evolves, the Company periodically reevaluates this size of the unhedged portfolio and may accordingly adjust up or down its currency hedging targets. See Part I, Item 1A. Risk Factors for the risk factor titled "The Company is exposed to foreign currency fluctuations in the yen/dollar exchange rate" for additional information.

Corporate and Other

The Company is exposed to currency risk when Japanese yen funds are converted into U.S. dollars. This occurs when Japanese yen-denominated funds are paid as dividends and management fees from Aflac Japan to the Parent Company and with quarterly settlements of internal reinsurance transactions. The foreign exchange rates prevailing at the time of Japanese yen payments will differ from the foreign exchange rates prevailing at the time the Japanese yen profits were earned. The Company may use a portion of the Japanese yen dividend and management fee payments to service Aflac Incorporated's Japanese yen-denominated notes payable with the remainder converted into U.S. dollars. Internal reinsurance transactions create foreign currency exposure at Aflac Re, primarily due to Japanese yen-denominated reinsurance liabilities to Aflac Japan while a majority of Aflac Re's assets are denominated in U.S. dollars, which may require Aflac Re to convert U.S. dollars to Japanese yen or enter foreign exchange derivatives with the Parent Company to manage Japanese yen-denominated liabilities.

In addition to Japanese yen payments and internal reinsurance transactions, certain investment activities for Aflac Japan expose the Company to economic currency risk when Japanese yen are converted into U.S. dollars. As noted above, the Company invests a portion of its Japanese yen cash flows in U.S. dollar-denominated assets. This requires that the Company convert the Japanese yen cash flows to U.S. dollars before investing. As previously discussed, for certain of its U.S. dollar-denominated securities, the Company enters into foreign currency forward and option contracts to hedge the currency risk on the fair value of hedged investments. Additionally, the Parent Company enters into forward contracts to accomplish a dual objective of hedging foreign currency rate risk to dividend payments by Aflac Japan, and reducing enterprise-wide hedge costs. The Company also balances the volume of hedging instruments between forwards and options in an attempt to manage and balance the risks associated with collateral, hedge costs and cash settlements. If the markets experience a significant strengthening of Japanese yen, this could cause cash strain at the Parent Company as a result of cash collateral and potentially cash settlement requirements. Based on the timing and severity of foreign exchange rate fluctuations combined with the level of outstanding activity in this program, the cash strain at the Parent Company could be significant.

Aside from the activities discussed above, the Company generally does not convert Japanese yen into U.S. dollars; however, it does translate financial statement amounts from Japanese yen into U.S. dollars for financial reporting purposes. Therefore, reported amounts are affected by foreign currency fluctuations. The Company reports unrealized foreign currency translation gains and losses in accumulated other comprehensive income (loss). In periods when the Japanese yen weakens against the dollar, translating Japanese yen into U.S. dollars causes fewer U.S. dollars to be reported. When the Japanese yen strengthens, translating Japanese yen into U.S. dollars causes more U.S. dollars to be reported. The weakening of the Japanese yen relative to the U.S. dollar will generally adversely affect the value of the Company's Japanese yen-denominated investments in U.S. dollar terms. The Company also considers the economic equity surplus in Aflac Japan and related exposure to foreign currency. The Company manages this currency risk by investing a portion of Aflac Japan's investment portfolio in U.S. dollar-denominated securities and by the Parent

Company's issuance of Japanese yen-denominated debt. As a result, the effect of currency fluctuations on the Company's net assets is reduced.

(4) Does not include U.S. dollar-denominated bonds that have corresponding cross-currency swaps in consolidated VIEs

The Company is required to consolidate certain VIEs. Some of the consolidated VIEs held by Aflac Japan use foreign currency swaps to convert foreign denominated cash flows to Japanese yen, the functional currency of Aflac Japan, in order to minimize cash flow fluctuations. Foreign currency swaps exchange an initial principal amount in two currencies, agreeing to re-exchange the currencies at a future date, at an agreed upon foreign exchange rate. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Prior to consolidation, the Company's beneficial interest in these VIEs was a Japanese yen-denominated available-for-sale security. Upon consolidation, the original Japanese yen-denominated investment was derecognized and the underlying fixed maturity securities and cross-currency swaps were recognized. The combination of a U.S. dollar-denominated investment and cross-currency swap economically creates a Japanese yen-denominated investment and has no impact on the Company's net investment hedge position.

Similarly, the combination of the U.S. corporate bonds and the foreign currency forwards and options that the Company has entered into, as discussed in the Aflac Japan Investment subsection of MD&A, economically creates a Japanese yen-denominated investment that qualifies for inclusion as a component of the Company's investment in Aflac Japan for net investment hedge purposes.

Interest Rate Risk

The Company's primary interest rate exposure is to the impact of changes in interest rates on the fair value of its investments in fixed maturity securities. Significant increases in interest rates cause declines in the values of the Company's investment portfolio which also has a secondary impact on the Company's overall evaluation of its deferred tax asset position. The Company monitors its investment portfolio on a quarterly basis utilizing a full valuation methodology, measuring price volatility, and sensitivity of the fair values of its investments to interest rate changes on the fixed maturity securities the Company owns. For example, if the current duration of a fixed maturity security is 10 years, then the fair value of that security will increase by approximately 10% if market interest rates decrease by 100 basis points, assuming all other factors remain constant. Likewise, the fair value of the debt security will decrease by approximately 10% if market interest rates increase by 100 basis points, assuming all other factors remain constant.

The estimated effect of potential increases in interest rates on the fair values of fixed maturity securities and loans the Company owns; derivatives and notes payable as of December 31 follows:

There are various factors that affect the fair value of the Company's investments in fixed maturity securities. Included in those factors are changes in the prevailing interest rate environment, which directly affect the balance of unrealized gains or losses for a given period in relation to a prior period. Decreases in market yields generally improve the fair value of fixed maturity securities, while increases in market yields generally have a negative impact on the fair value of the Company's fixed maturity securities. However, the Company does not expect to realize a majority of any unrealized gains or losses. For additional information on unrealized losses on fixed maturity securities, see Note 3 of the Notes to the Consolidated Financial Statements.

The Company attempts to match the duration of its assets with the duration of its liabilities. The following table presents the approximate duration of Japanese yen-denominated assets and liabilities of Aflac Japan, along with premiums, as of December 31.

Aflac Japan investment yields above include U.S. dollar-denominated investment yields prior to factoring in amortized hedge costs. The Company continues to monitor the spread between its new money yield and the required interest assumption for newly issued products in both the U.S. and Japan and will re-evaluate those assumptions as necessary. Currently, when investments the Company owns mature, the proceeds may be reinvested at a yield below that of the interest required for the accretion of policy benefit liabilities on policies issued in earlier years. Overall, adequate profit margins exist in Aflac Japan's aggregate block of business because of changes in the mix of business and favorable experience from mortality, morbidity and expenses.

Periodically, the Company may enter into derivative transactions to hedge interest rate risk, depending on general economic conditions. For additional information on interest rate derivatives, see the Hedging Activities subsection of Item 7. MD&A and Note 4 of the Notes to the Consolidated Financial Statements.

Credit Risk

A significant portion of the Company's investment portfolio consists of fixed maturity securities and loans that expose it to the credit risk of the underlying issuer or borrower. The Company carefully evaluates this risk on every new investment and closely monitors the credit risk of its existing investment portfolio. The Company incorporates the needs of its products and liabilities, the overall requirements of the business, and other factors in addition to its underwriting of the credit risk for each investment in the portfolio.

Evaluating the underlying risks in the Company's credit portfolio involves a multitude of factors including but not limited to its assessment of the issuer's or borrower's business activities, assets, products, market position, financial condition, and future prospects, including sustainability of the issuer’s or borrower’s business. The Company incorporates the assessment of the NRSROs in assigning credit ratings and incorporates the rating methodologies of its external managers in assigning loan ratings to portfolio holdings. The Company performs extensive internal assessments of the credit risks for all its portfolio holdings and potential new investments, which includes using analyses provided by the Company's specialist external managers. For assets managed by external asset managers, the Company provides investment and credit risk parameters that must be used when making investment decisions and requires ongoing monitoring and reporting from the asset managers on significant changes in credit risks within the portfolio.

As previously disclosed, the Company owns long-dated fixed maturity securities in support of its long-dated policyholder obligations. Some of the Company's largest global investment holdings are positions that were purchased many years ago and increased in size due to merger and consolidation activity among the issuing entities. In addition, many of the Company's largest holdings are Japanese yen-denominated, therefore strengthening of the Japanese yen can increase its position in U.S. dollars, and weakening of the Japanese yen can decrease its position in U.S. dollars. The Company's global investment guidelines establish concentration limits for its investment portfolios.

The primary factor considered when determining the domicile of investment exposure is the legal country risk location of the issuer. However, other factors such as the location of the parent guarantor, the location of the company's headquarters or major business operations (including location of major assets), location of primary market (including location of revenue generation) and specific country risk publicly recognized by rating agencies can influence the assignment of the country (or geographic) risk location. When the issuer is a special financing vehicle or a branch or subsidiary of a global company, then the Company considers any guarantees and/or legal, regulatory and corporate relationships of the issuer relative to its ultimate parent in determining the proper assignment of country risk.



77
Derivative Counterparties

The Company is a direct counterparty to the majority of derivative instruments and is exposed to credit risk in the event of nonperformance by the counterparties in those contracts. For the foreign currency swaps associated with the Company's VIE investments for which it is the primary beneficiary, the Company bears the risk of foreign exchange and/or credit loss due to counterparty default even though it is not a direct counterparty to those contracts. The risk of counterparty default for the Company's VIE and senior note and subordinated debenture swaps, foreign currency swaps, certain foreign currency forwards, foreign currency options and interest rate swaptions is mitigated by collateral posting requirements that counterparties to those transactions must meet. If collateral posting agreements are not in place or the counterparty defaults on its collateral posting obligations, the counterparty risk associated with foreign currency forwards and foreign currency options is the risk that at expiry of the contract, the counterparty is unable to deliver the agreed upon amount of Japanese yen at the agreed upon price or delivery date, thus exposing the Company to additional unhedged exposure to U.S. dollars held in the Aflac Japan investment portfolio. See Note 4 of the Notes to the Consolidated Financial Statements for additional information.

Equity Risk

Market prices for equity securities are subject to fluctuation and consequently the amount realized in the subsequent sale of an investment may significantly differ from the reported market value. Fluctuation in the market price of a security may result from the relative price of alternative investments and general market conditions. The Company's three largest equity exposures had a fair value of $184 million or approximately 21% of its total investment in equity securities as of December 31, 2025. If equity prices experienced a hypothetical broad-based decline of 10%, the fair value of the Company's equity investments would decline by approximately $89 million.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors
Aflac Incorporated:

Opinion on Internal Control Over Financial Reporting
We have audited Aflac Incorporated and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of earnings, comprehensive income (loss), shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes and financial statement schedules II, III, and IV (collectively, the consolidated financial statements), and our report dated February 25, 2026 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors
Aflac Incorporated:

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Aflac Incorporated and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of earnings, comprehensive income (loss), shareholders’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2025, and the related notes and financial statement schedules II, III, and IV (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 25, 2026 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Fair value of certain privately issued securities
As discussed in Note 5 to the consolidated financial statements, the fair values of certain privately issued securities are estimated using a discounted cash flow valuation model, developed by a third-party pricing vendor and executed by Company personnel. This model takes into consideration any unique characteristics of the securities and makes various adjustments to arrive at an appropriate issuer-specific loss adjusted credit curve using the most appropriate comparable security(ies) of the issuer and issuer-specific credit default swap spreads. This credit curve is then used with the relevant recovery rates to estimate expected cash flows and modeling of additional features, including illiquidity adjustments, if necessary, to price the security by discounting those loss adjusted cash flows. Judgment is required to determine the inputs and assumptions used in the valuation model, including the determination of the most appropriate comparable securities to develop an issuer-specific loss adjusted credit curve when it cannot be developed from the specific security features. As of December 31, 2025, the values of certain privately issued securities are included within the financial statement captions of fixed maturity securities available-for-sale, at fair


81
value of $60.5 billion; fixed maturity securities available-for-sale consolidated variable interest entities, at fair value of $3.6 billion; and, fixed maturity securities held-to-maturity, at amortized cost of $16.1 billion.
We identified the assessment of the fair values of certain privately issued securities as a critical audit matter. Due to the complexity of the valuation model, subjective auditor judgment and specialized valuation skills and knowledge were needed to evaluate the valuation model, the methodology used to estimate fair value, and the Company's determination of the most appropriate comparable securities to develop an issuer-specific loss adjusted credit curve, when necessary.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls, with the assistance of valuation professionals, over the Company’s process to estimate the fair values of certain privately issued securities. This included controls over the Company’s determination of comparable securities, when appropriate, to develop an issuer-specific loss adjusted credit curve to be used in the valuation model to estimate fair values. We involved valuation professionals with specialized skills and knowledge to assist in assessing the estimated fair values of such securities, which included
•Evaluating the Company's valuation methodology for compliance with U.S. generally accepted accounting principles
•Assessing the Company's model to estimate the fair values of privately issued securities by determining that differences in fair values between that model and an independent internal model above pre-established tolerances, if any, were investigated by the Company
•Evaluating, for a selection of privately issued securities, the comparable securities used to develop an issuer-specific loss adjusted credit curve by assessing whether the determination of comparable securities was reasonable based on the Company’s methodology and our knowledge of the securities and the markets for such securities
•Developing an independent estimate of fair value for a selection of privately issued securities based on independently developed valuation models and assumptions, as applicable, using market data sources and comparing our independent estimate to the Company's fair value.
Valuation of the liability for future policy benefits
As discussed in Note 1 and Note 7 to the consolidated financial statements, the liability for future policy benefits (LFPB) is determined using the net level premium method as the present value of expected future policy benefits to be paid to or on behalf of policyholders and certain related expenses less the present value of expected future net premiums receivable under the Company's insurance contracts, where expected future net premiums receivable are future gross premiums receivable under the contract multiplied by the net premium ratio (NPR). Future policy benefits are calculated using assumptions and estimates including, (1) cash flow assumptions (mortality, morbidity, and terminations, also referred to as lapses), (2) expense assumptions and (3) discount rates. Cash flow assumptions are established at policy inception and are evaluated each quarter to determine if an update is needed. Discount rates used to calculate net premiums are locked in at policy inception and represent the basis to recognize interest expense accreted on insurance reserves included in benefits and claims, excluding reserve remeasurement in the consolidated statements of earnings. Discount rates used to measure the carrying value of the LFPB in the consolidated balance sheets are updated each reporting period, and the difference between the liability balances calculated using the locked-in discount rates and the updated discount rates is included in the effect of changes in discount rate assumptions in accumulated other comprehensive income (loss) (AOCI). The Company’s LFPB was $62.3 billion as of December 31, 2025.
We identified the evaluation of certain assumptions used in estimating the LFPB as a critical audit matter. A high level of auditor effort, including specialized skills and knowledge and subjective auditor judgment was involved in the evaluation of actuarial methodologies, certain cash flow assumptions (mortality, morbidity, and termination), and the discount rate curve assumptions for Japan.
The following are the primary procedures we performed to address this critical audit matter. With the assistance of valuation and actuarial professionals, we evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s LFPB. This included controls related to actuarial methodologies and the development of certain cash flow assumptions (mortality, morbidity, and termination) and the discount rate curve. We involved valuation professionals with specialized skills and knowledge to assist in assessing the methodology and assumptions used by the Company to develop the discount rate curve for Japan by developing an independent


82
discount rate curve and comparing it to that used by the Company. We also involved actuarial professionals with specialized skills and knowledge, who assisted in
•Assessing the actuarial methodologies used by the Company to estimate the LFPB for consistency with generally accepted actuarial methodologies
•Evaluating certain of the Company's cash flow assumptions (mortality, morbidity, and termination) by assessing them in comparison to the Company’s relevant historical experience data and anticipated trends
•Evaluating the Company’s LFPB estimate by recalculating the projected cash flows for a selection of policies and comparing the results to the Company’s estimates.

Aflac Incorporated and Subsidiaries
Notes to the Consolidated Financial Statements
1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Description of Business
Aflac Incorporated (the Parent Company) and its subsidiaries (collectively, the Company) primarily sell supplemental health and life insurance in Japan and the United States (U.S.). The Company's insurance business is marketed and administered through Aflac Life Insurance Japan Ltd. (ALIJ) in Japan and through American Family Life Assurance Company of Columbus (Aflac), American Family Life Assurance Company of New York (Aflac New York), Continental American Insurance Company (CAIC), Tier One Insurance Company (TOIC) and Aflac Benefits Solutions, Inc. (ABS) in the U.S. The Company’s operations consist of two reportable business segments: Aflac Japan, which includes ALIJ, and Aflac U.S., which includes Aflac, Aflac New York, CAIC, TOIC, and ABS. Aflac New York is a wholly owned subsidiary of Aflac. Most of the Aflac U.S. policies are individually underwritten and marketed through independent agents. With the exception of dental and vision products administered by ABS, and certain group life insurance products, Aflac U.S. markets and administers group products through CAIC, branded as Aflac Group Insurance. Additionally, Aflac U.S. markets its consumer markets products through TOIC. The Company's insurance operations in the U.S. and Japan service the two markets for the Company's insurance business. The Parent Company, other operating business units that are not individually reportable, reinsurance activities, including internal reinsurance activity with Aflac Re Bermuda Ltd. (Aflac Re), and other business activities not included in Aflac Japan or Aflac U.S., as well as intercompany eliminations, are included in Corporate and other.

Basis of Presentation
The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles (U.S. GAAP). These principles are established primarily by the Financial Accounting Standards Board (FASB). In these Notes to the Consolidated Financial Statements, references to U.S. GAAP issued by the FASB are derived from the FASB Accounting Standards CodificationTM (ASC). The consolidated financial statements include the accounts of the Parent Company, its subsidiaries, and those entities required to be consolidated under applicable accounting standards. All material intercompany accounts and transactions have been eliminated.

Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates based on currently available information when recording transactions resulting from business operations. The most significant items on the Company's balance sheet that involve a greater degree of accounting estimates and actuarial determinations subject to changes in the future are the valuation of investments and derivatives, deferred policy acquisition costs (DAC), liabilities for future policy benefits (LFPB) and income taxes. These accounting estimates and actuarial determinations are sensitive to market conditions, investment yields, interest rates, mortality, morbidity, commission and other acquisition expenses and terminations by policyholders. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised and reflected in the consolidated financial statements. Although some variability is inherent in these estimates, the Company believes the amounts provided are reasonable and reflective of the best estimates of management.

Significant Accounting Policies
Foreign Currency Translation and Remeasurement: The functional currency of Aflac Japan is the Japanese yen. The Company translates its Japanese yen-denominated financial statement accounts into U.S. dollars as follows.

•Assets and liabilities are translated at end-of-period foreign exchange rates.
•Realized gains and losses on security transactions are translated at the foreign exchange rate on the trade date of each transaction.
•Other revenues, expenses, and cash flows are translated using average foreign exchange rates for the period.

The resulting foreign currency translation adjustments are included in accumulated other comprehensive income.

Foreign currency gains and losses resulting from the remeasurement of foreign currency and realized foreign currency exchange gains and losses are included in net investment gains (losses) in the consolidated statements of earnings.


90
The Parent Company has designated a majority of its Japanese yen-denominated liabilities (Japanese yen-denominated notes payable and Japanese yen-denominated loans) as non-derivative hedges and foreign currency forwards and options as derivative hedges of the foreign currency exposure of the Parent Company's net investment in Aflac Japan. The gains or losses on hedging derivative instruments and the foreign currency remeasurement gains or losses on the non-derivative hedging instruments that are designated as, and are effective as, an economic hedge of the net investment in Aflac Japan are reported as unrealized foreign currency translation gains (losses) in other comprehensive income and are included in accumulated other comprehensive income.

Insurance Revenue and Expense Recognition: Substantially all supplemental health and life insurance policies the Company issues are classified as long-duration contracts. The contract provisions generally cannot be changed or canceled during the contract period. However, the Company may adjust premiums for supplemental health policies issued in the U.S. within prescribed guidelines and with the approval of state insurance regulatory authorities.

Insurance premiums for most of the Company's health and life insurance policies are recognized as earned premiums over the premium-paying periods of the contracts when due from policyholders. When earned premiums are reported, the related amounts of benefits and expenses are charged against such revenues. This association is accomplished by means of annual increases or decreases to the LFPB and the deferral and subsequent amortization of policy acquisition costs.

Premiums from the Company's products with limited-pay features are collected over a significantly shorter period than the contract term (i.e., the period during which benefits are provided). Premiums for these products are recognized as earned premiums over the premium-paying periods when due from policyholders. Any gross premium in excess of the net premium is deferred and reported as a deferred profit liability, which is subsequently amortized in net earned premiums such that profits are recognized in a constant relationship with insurance in force.

Net premium is calculated as gross premium multiplied by the net premium ratio (NPR) and represents the portion of gross premium required to provide for benefits and expenses. Benefits are recorded as an expense when they are incurred and LFPB is recorded when premiums are recognized using the net premium method.

Policyholders also have an option to pay discounted advanced premiums for certain of the Company's products. Advanced premiums are deferred and recognized when due from policyholders over the otherwise required contractual premium payment period.

Benefit expense is bifurcated between benefits and claims and reserve remeasurement (gains) losses. The NPR is used to measure benefit expense and is calculated as the ratio of the present value of actual and future expected benefits and expenses to the present value of actual and future expected gross premiums. A revised NPR is calculated as of the beginning of each reporting period using updated future cash flow expectations.

Benefits and claims represent the difference in the liability balance calculated as of the beginning of the current reporting period and the end of the current reporting period both using the revised NPR and the locked-in discount rates.

Reserve remeasurement (gains) losses represent the difference between two reserve measures both calculated as of the beginning of the current reporting period using the same locked-in discount rates. One reserve measure uses the NPR as of the end of the prior reporting period, and the second uses the revised NPR.

The locked-in interest accretion rate utilized for accretion of interest expense on insurance reserves is the original discount rate used at contract issue date.

Advertising expense is reported as incurred and included in insurance and other expenses in the consolidated statements of earnings. For the years ended December 31, 2025, 2024 and 2023, advertising expense was $160 million, $181 million and $188 million, respectively.

Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, money market instruments, and other debt instruments with a maturity of 90 days or less when purchased.


91
Investments:

Fixed Maturity and Equity Securities

The Company's fixed maturity securities are classified as either held-to-maturity or available-for-sale. Fixed maturity securities classified as held-to-maturity are securities that the Company has the ability and intent to hold to maturity or redemption and are carried at amortized cost, net of allowance for credit losses.

All other fixed maturity securities are classified as available-for-sale and are carried at fair value. If the fair value is higher than the amortized cost, the excess is an unrealized gain, and if lower than cost, the difference is an unrealized loss. The net unrealized gains and losses on securities available-for-sale, less related deferred income taxes, are reported in other comprehensive income and included in accumulated other comprehensive income.

Amortized cost of fixed maturity securities is based on the Company's purchase price adjusted for accrual of discount, or amortization of premium, and recognition of impairment charges, if any. The amortized cost of fixed maturity securities the Company purchases at a discount or premium will equal the face or par value at maturity or the call date, if applicable. Interest is reported as net investment income when earned and is adjusted for the amortization of any premium or discount.

For mortgage- and asset-backed securities, the Company recognizes income using a constant effective yield, which is based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments.

The Company has investments in marketable equity securities which are carried at fair value. Changes in the fair value of equity securities are included in net investment gains (losses) in the consolidated statements of earnings. Dividends are included in net investment income when declared.

The Company uses the specific identification method to determine the gain or loss from securities transactions. The realized gain or loss is included in net investment gains (losses) in the consolidated statements of earnings. Securities transactions are accounted for based on values as of the trade date of the transaction.

Commercial Mortgage and Other Loans

Commercial mortgage and other loans include transitional real estate loans (TREs), commercial mortgage loans (CMLs), middle market loans (MMLs), and other loans. The Company's investments in TREs, CMLs, MMLs, and other loans are accounted for as loan receivables and are reported at amortized cost on the acquisition date. The Company has the intent and ability to hold these loan receivables for the foreseeable future or until they mature; therefore, they are considered held for investment and are carried at amortized cost, net of allowance for credit losses, and included in commercial mortgage and other loans in the consolidated balance sheets. Income on commercial mortgage and other loans is recognized using the interest method and included in net investment income in the consolidated statements of earnings.

The Company designates nonaccrual status for a nonperforming fixed maturity security or loan receivable or a fixed maturity security or loan receivable that is not generating its stated interest rate because of nonpayment of periodic interest or principal by the borrower. The Company applies the cash basis method to record any payments received on nonaccrual assets. The Company resumes the accrual of interest on fixed maturity securities and loan receivables that are currently making contractual payments or for those that are not current where the borrower has paid timely (less than 30 days outstanding).

Other Investments

Other investments include limited partnerships, real estate owned (REO), short-term investments with maturities at the time of purchase of one year or less, but greater than 90 days, and policy loans.

Limited partnerships are accounted for using the equity method of accounting. Under the equity method of accounting, the Company reports its proportionate share of the investee's earnings or losses as a component of net investment income in the consolidated statements of earnings. The underlying investments held by the Company’s limited partnerships primarily consist of private equity and real estate.


92
In addition, the Company invests in partnerships that primarily specialize in rehabilitating historic structures or the installation of solar equipment that are tax equity investments. These investments derive investment returns in the form of income tax credits or other tax incentives. Beginning January 1, 2024, tax equity investments that meet certain criteria are accounted for using the proportional amortization method, where the initial cost of the investment is amortized in proportion to the tax credits received and recognized as a component of income tax expense (benefit). Tax equity investments that do not meet the qualification criteria for the proportional amortization method are accounted for using the equity method of accounting.

REO represents commercial properties obtained through foreclosure or deed in lieu of foreclosure of certain of the Company's loan receivables. REO is classified as held-and-used for the production of income or held-for-sale. When held-and-used for the production of income, REO is recorded at fair value upon acquisition, which establishes the property’s initial cost basis. Thereafter, it is carried at cost less accumulated depreciation and written down to fair value for impairment losses. When held-for-sale, REO is initially recorded at fair value less costs to sell and is subsequently carried at the lower of the initial carrying value or fair value less costs to sell and is not depreciated.

REO depreciation is recorded on a straight-line basis over the estimated useful life of the asset and is included in net investment income. A review for impairment is performed whenever events or circumstances indicate that the carrying value may not be recoverable. An impairment loss is included in net investment gains (losses) when the carrying value of the property exceeds the expected undiscounted cash flows generated from the property. Net operating income earned on REO is included in net investment income in the consolidated statements of earnings.

Short-term investments are reported at amortized cost, which approximates fair value.

Variable Interest Entities (VIEs)

The Company has investments in VIEs, which consist of fixed maturity securities, loan receivables, limited partnerships and derivative instruments. The Company is the primary beneficiary of the VIE if the Company has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance and (2) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE. If the Company determines that it is the primary beneficiary of the VIE, it consolidates these entities in its consolidated financial statements. Consolidated VIEs are segregated by the caption "consolidated variable interest entities" in the consolidated balance sheets.

While the consolidated VIEs generally operate within a defined set of contractual terms, there are certain powers that are retained by the Company that are considered significant in the conclusion that the Company is the primary beneficiary. These powers vary by structure but generally include:

•the initial selection of the underlying collateral;
•the ability to obtain the underlying collateral in the event of default; and
•the ability to appoint or dismiss key parties in the structure.

The Company's powers surrounding the underlying collateral were the most significant powers considered due to the impact these powers have on the economics of the VIE. The Company has no obligation to provide any continuing financial support to any of the entities in which it is the primary beneficiary. The Company's maximum loss is limited to its original investment and, in certain cases, to any unfunded commitment held in the VIE. Neither the Company nor any of its creditors have the ability to obtain the underlying collateral, nor does the Company have control over the instruments held in VIEs, unless there is an event of default.

Securities Lending and Pledged Assets

The Company lends fixed maturity securities and, from time to time, public equity securities to financial institutions in short-term security-lending transactions. These short-term securities lending arrangements are primarily used to earn investment income. These securities continue to be reported as investment assets in the consolidated balance sheets during the terms of the loans and are not reported as sales. The Company receives cash or other securities as collateral for such loans. When the Company obtains non-cash collateral it amounts to 102% or more of the fair value of the loaned securities. When unrestricted cash is received as collateral it is equivalent to 100% or more of the fair value of the loaned securities. For loans involving unrestricted cash or securities as collateral, the collateral is reported as an asset with a corresponding liability for the return of the collateral. For loans where the Company receives as collateral securities that the Company is not permitted to sell or repledge, the collateral is not reflected in the consolidated financial statements.


93
Allowance for Credit Losses: The Company estimates an allowance for credit losses on the following financial assets:

•Fixed maturity securities
◦Available-for-sale securities
◦Held-to-maturity securities
•Loan receivables and loan commitments
•Short-term receivables
•Premiums receivable
•Reinsurance recoverables

For available-for-sale and held-to-maturity securities, loan receivables, including collateral dependent assets and certain loan commitments, changes in the allowance for credit losses are included in net investment gains (losses) in the consolidated statements of earnings. Write-offs and partial write-offs are reported as a reduction to the amortized cost of the fixed maturity security or loan receivable with a corresponding reduction to the allowance for credit losses.

For available-for-sale securities, the Company evaluates estimated credit losses only when the fair value of the available-for-sale security is below its amortized cost basis.

The Company’s off-balance sheet credit exposure is primarily attributable to loan commitments that are not unconditionally cancellable. The allowance for credit losses for these loan commitments is included in other liabilities in the consolidated balance sheets.

For premiums receivable, changes in the allowance for credit losses are included in net earned premiums in the consolidated statements of earnings. The Company estimates an allowance for credit losses for premiums receivable utilizing an aging methodology based on historical loss information, adjusted for current conditions and reasonable and supportable forecasts. Premiums receivable are reported net of the allowance for credit losses and included in receivables in the consolidated balance sheets.

For reinsurance recoverables, changes in the allowance for credit losses are included in net investment gains (losses) in the consolidated statements of earnings. Reinsurance recoverables are reported net of the allowance for credit losses and included in other assets in the consolidated balance sheets.

The Company has elected not to estimate an allowance for credit losses on accrued interest income for all asset types. The Company writes off accrued interest when it is more than ninety days past due by reducing interest income, which is included in net investment income in the consolidated statements of earnings.

For additional information on the Company's methodology for calculating allowance for credit losses, see Notes 3 and 8.
Derivatives and Hedging:

Freestanding Derivative Instruments

Freestanding derivative instruments are reported at fair value and included in other assets and other liabilities in the consolidated balance sheets. These instruments may include foreign currency forwards, foreign currency options, foreign currency swaps, interest rate swaps and interest rate swaptions. These derivative instruments are typically used to reduce exposure to risks such as foreign currency exchange or interest rate. The Company does not use derivatives for trading purposes.

Changes in the fair value of derivative instruments not designated as an accounting hedge or that do not qualify for hedge accounting are included in net investment gains (losses) in the consolidated statements of earnings.

Accruals on derivatives are included in other assets or other liabilities in the consolidated balance sheets.

Hedge Accounting

From time to time, the Company designates as hedging instruments derivative and non-derivative instruments that meet the requirements for hedge accounting. To qualify for hedge accounting, the instrument must be highly effective in mitigating the designated risk attributable to the hedged item.

At the inception of hedging relationships, the Company formally documents all relationships between hedging instruments


94
and hedged items, as well as its risk-management objectives and strategies for undertaking the respective hedging relationship. The Company also documents its hedge accounting designation and the methodology that will be used to assess the effectiveness of the hedging relationship at and after hedge inception. The documentation process includes linking derivatives and non-derivative financial instruments that are designated in hedging relationships with specific assets or groups of assets or liabilities in the consolidated balance sheets or to specific forecasted transactions, as well as defining the effectiveness testing methods to be used.

The Company formally assesses whether the derivatives and non-derivative financial instruments used in hedging activities have been, and are expected to continue to be, highly effective in offsetting their designated risk. Hedge effectiveness is formally assessed at inception and on a quarterly basis throughout the life of the hedging relationship using qualitative and quantitative methods. Qualitative methods may include the comparison of critical terms of the derivative to the hedged item. Quantitative methods may include regression, dollar offset, or other statistical analysis of changes in fair value or cash flows associated with the hedging relationship.

The assessment of hedge effectiveness determines the accounting treatment of changes in fair value.

Hedge accounting designations are cash flow hedge, fair value hedge, or net investment hedge.

Cash Flow Hedge

A cash flow hedge is a hedge of the variability of cash flows to be received or paid related to a recognized asset or liability or the hedge of a forecasted transaction.

For derivative instruments that are designated in cash flow hedging relationships, the gain or loss on the portion of the hedging instrument included in the assessment of effectiveness is included in unrealized gains (losses) on derivatives in the consolidated statements of comprehensive income (loss). Amounts included in accumulated other comprehensive income are reclassified into earnings in the same period or periods during which the hedged transaction affects earnings and are included in the same line item in the consolidated statements of earnings as the hedged item.

Fair Value Hedge

A fair value hedge is a hedge of the exposure to changes in the fair value of a recognized asset or liability, attributable to a particular risk.

For derivative instruments that are designated in highly effective fair value hedge relationships, the effective portion of the gain or loss of the hedging instrument included in the assessment of effectiveness is included in the line item of the consolidated statements of earnings in which gain or loss on the hedged item is included.

Net Investment Hedge

A net investment hedge is a hedge of foreign currency exposure of a net investment in a foreign operation. The Company designates and accounts for certain foreign currency forwards and options as net investment hedges of the Company's net investment in Aflac Japan when they meet the requirements for hedge accounting. The Company also designates the Parent Company’s Japanese yen-denominated liabilities as a non-derivative net investment hedge of the Company's net investment in Aflac Japan. For additional information on the Parent Company’s Japanese yen-denominated liabilities, see Note 9.

At the beginning of each quarter, the Company makes its net investment hedge designation for foreign currency derivatives and Japanese yen-denominated liabilities. For foreign currency derivatives designated as net investment hedges, the Company assesses hedge effectiveness using the spot-rate method. According to this method, the change in fair value of the hedging instrument due to fluctuations in the spot exchange rate is included in unrealized foreign currency translation gains (losses) in the statements of comprehensive income (loss). For Japanese-yen denominated liabilities designated as net investment hedges, the foreign currency translation gain or loss determined by references to the spot foreign exchange rate is also included in unrealized foreign currency translation gains (losses) in the statements of comprehensive income (loss).

Amounts included in accumulated other comprehensive income are reclassified to earnings only when the hedged net investment is sold or when a liquidation of the respective net investment in the foreign entity is substantially completed. When a sale or liquidation occurs, the deferred gain or loss is reclassified to earnings and included in the same line item in the consolidated statements of earnings as the gain or loss on the sale of the hedged net investment.


95

All other changes in fair value of the foreign currency derivatives designated as net investment hedges are excluded from the assessment of hedge effectiveness and are included in net investment gains (losses) in the consolidated statements of earnings.

Should these designated net investment hedge positions exceed the Company's net investment in Aflac Japan, the foreign currency exchange effect on the excess portion is included in net investment gains (losses) in the consolidated statements of earnings.

Hedge Accounting Termination

The Company discontinues hedge accounting prospectively when (1) it is determined that the derivative is no longer highly effective in offsetting changes in the estimated cash flows or fair value of a hedged item; (2) the derivative is de-designated as a hedging instrument; or (3) the derivative expires or is sold, terminated or exercised.

When hedge accounting is discontinued on a cash flow or fair value hedge, the derivative is reported at fair value in the consolidated balance sheets, with changes in the fair value included in net investment gains (losses) in the consolidated statements of earnings. For discontinued cash flow hedges, including those where the derivative is sold, terminated or exercised, changes in the fair value included in accumulated other comprehensive income are reclassified to earnings when earnings are impacted by the cash flow of the hedged item.

Embedded Derivatives

The Company may purchase certain investments or enter into contracts that contain embedded derivatives. The Company assesses whether an embedded derivative is clearly and closely related to its host contract. If the Company determines that the embedded derivative is not clearly and closely related to the host contract, and a separate instrument with the same terms would qualify as a derivative instrument, the embedded derivative is separated from that contract and reported at fair value with the host instrument in the consolidated balance sheets. Changes in the fair value are included in current period earnings. If the Company has elected the fair value option, the embedded derivative is not bifurcated, and the entire investment is held at fair value with changes in fair value included in current period earnings.

Pledged Collateral

The Company receives and pledges cash or other securities as collateral on open derivative positions.

Cash received as collateral is reported as an asset with a corresponding liability for the return of the collateral. Cash pledged as collateral is recorded as a reduction to cash, and a corresponding receivable is recognized for the return of the cash collateral.

The Company generally can repledge or resell collateral obtained from counterparties, although the Company does not typically exercise such rights. Securities received as collateral are not recognized unless the Company were to exercise its right to sell that collateral or exercise remedies on that collateral upon a counterparty default. Securities that the Company has pledged as collateral continue to be carried as investment assets in the consolidated balance sheets.

The Company does not offset amounts recognized for derivative instruments and amounts recognized for the right to reclaim or the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement.

For additional information on the Company's derivative instruments, see Note 4. For additional information on the Company's valuation methodology for derivatives, see Note 5.

Deferred Policy Acquisition Costs: The Company incurs significant costs in connection with acquiring new and renewal insurance business. Costs that are related directly to the successful acquisition of new or the renewal of existing insurance contracts are capitalized as DAC. DAC primarily includes the excess of current-year commissions over ultimate renewal-year commissions and certain direct and incremental policy issue, underwriting and sales expenses directly related to successful policy acquisition.

DAC is amortized on a grouped-contract basis over the expected term of the related contracts, using a constant-level basis, as follows:


96
Policy TypeConstant-level Basis
Life Products (U.S.)Face Amount
Health Products (U.S.)Number of Policies in Force
Health & Life Products (Japan)Units in Force

Face amount is the stated dollar amount that the policy’s beneficiaries receive upon the death of the insured. For life and health products issued in Japan, the constant-level basis used is units in force, which is a proxy for the face amount and insurance in force, respectively.

Amortization is computed using the same contract groupings (also referred to as cohorts) and mortality and termination assumptions that are used in computing the LFPB. These assumptions are reviewed and updated at least annually. The effects of changes in assumptions are recognized prospectively over the remaining contract term as a revision of the future amortization pattern, while current period amortization is calculated based on the actual experience during the quarter.

Internal Replacements

For some products, policyholders can elect to modify product benefits, features, rights or coverages. These transactions are known as internal replacements and can occur by:

•exchanging a contract for a new contract, or
•amendment, endorsement, or rider to a contract, or
•the election of a feature or coverage within a contract.

The Company performs the following two-step analysis of the internal replacements to determine if the modification is substantive to the base policy: (1) determine if the modification is integrated with the base policy, and (2) if it is integrated, determine if the resulting contract is substantially changed. Contract modifications resulting in integrated contract features can be determined only in conjunction with the value of the base policy. Non-integrated features are not related to or dependent on the value of the base policy.

For an internal replacement transaction that results in a policy that is integrated and substantially changed, the policy is treated as lapsed for amortization purposes, and the costs of acquiring the new policy are capitalized and amortized in accordance with the Company's accounting policies for DAC.

For internal replacement transactions where the resulting contract is integrated and substantially unchanged, unamortized DAC from the original policy continue to be amortized over the expected life of the cohort, and the costs of replacing the policy are accounted for as policy maintenance costs and expensed as incurred.

Non-integrated internal replacement transactions are accounted for as separately issued contracts within the cohort open at the effective date of the non-integrated feature. Any DAC related to the non-integrated contract feature or coverage are accounted for in accordance with the Company's accounting policies for DAC.
Property and Equipment: The costs of buildings, furniture and equipment are depreciated principally on a straight-line basis over their estimated useful lives (maximum of 50 years for buildings and 20 years for furniture and equipment). Expenditures for maintenance and repairs are expensed as incurred; expenditures for betterments are capitalized and depreciated. Classes of property and equipment as of December 31 were as follows:
(In millions)20252024
Property and equipment:
Land$168 $168 
Buildings399 392 
Equipment and furniture451 478 
Total property and equipment1,018 1,038 
Less accumulated depreciation667 651 
Net property and equipment$351 $387 


97
Depreciation and other amortization expenses, which are included in insurance and other expenses in the consolidated statements of earnings, were $36 million in 2025, compared with $40 million in 2024 and $39 million in 2023.

Goodwill: Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The amount of goodwill recognized is also impacted by measurement differences resulting from certain assets and liabilities not recorded at fair value (e.g. income taxes, employee benefits). Goodwill is not amortized, but is tested for impairment at a level of a reporting unit at least annually, in the same reporting period each year. Goodwill is included in the other assets line item in the consolidated balance sheets and was $260 million at December 31, 2025, compared with $263 million at December 31, 2024. A significant majority of the goodwill balance is attributable to business combinations within the Aflac U.S. segment, which represents the reporting unit for goodwill impairment testing.

Policy Liabilities: The Company's total policy liabilities consist of:

•Future policy benefits
•Unpaid policy claims
•Unearned premiums
•Other policyholders' funds

Future Policy Benefits

Long-duration insurance contracts issued by the Company are grouped into annual calendar-year cohorts based on the contract issue date, reportable segment, legal entity and product type. Limited-pay contracts are grouped into separate cohorts from other traditional products in the same manner and are further separated based on their premium payment structures. For long-duration insurance contracts, the Company calculates an integrated LFPB reserve that represents all payments under the contract including future expected claims, unpaid policy claims and related expenses.

The LFPB is determined using the net level premium method as the present value of expected future policy benefits to be paid to or on the behalf of policyholders and certain related expenses less the present value of expected future net premiums receivable under the Company’s insurance contracts, where expected future net premiums receivable are future gross premiums receivable under the contract multiplied by the NPR.

The LFPB is calculated using assumptions and estimates including, (1) cash flow assumptions (mortality, morbidity, and terminations, also referred to as lapses), (2) expense assumptions and (3) discount rates. The assumptions and estimates that the Company uses depend on its judgment regarding the likelihood of future events and are inherently uncertain.

Cash flow assumptions are established at policy inception and are evaluated each quarter to determine if an update is needed.

Actual experience is reflected in the calculation of future policy benefits each quarter, and changes in the liability due to actual experience are included in reserve remeasurement (gains) losses in the consolidated statements of earnings.

To facilitate a more detailed review of cash flow assumptions, experience studies are performed annually during the third quarter. Changes in cash flow assumptions are the result of applying the updated best estimate assumptions as of the beginning of the reporting period and are included as a cumulative catch-up adjustment in reserve remeasurement (gains) losses in the consolidated statements of earnings.

Expense assumptions are established at policy inception and determined for each issue-year cohort as a percentage of paid claims. These expense assumptions are locked in and remain unchanged over the term of the insurance policy.

Discount rates used to calculate net premiums are locked in at policy inception and represent the basis to recognize interest expense accreted on insurance reserves included in benefits and claims, excluding reserve remeasurement in the consolidated statements of earnings. These locked-in discount rates are determined separately for each issue-year cohort as a single discount rate that reflects the duration characteristics of the corresponding insurance contracts and will remain unchanged after the calendar year of issue.

Discount rates used to measure the carrying value of the LFPB in the consolidated balance sheets are updated each reporting period, and the difference between the liability balances calculated using the locked-in discount rates and the updated discount rates is included in the effect of changes in discount rate assumptions in accumulated other comprehensive income (loss).


98

The Company's discount rate methodology involves constructing a current discount rate curve separately for discounting cash flows used to calculate the Japan and U.S. LFPB, reflective of the characteristics of the insurance liabilities, such as currency and tenor. For additional information on the Company's discount rate methodology, see Note 7.

The difference in the liability balance calculated as of the beginning of the current reporting period and the end of the current reporting period both using the revised NPR and the locked-in discount rates is included in benefits and claims in the consolidated statements of earnings.

For internal replacements that are determined to be substantially changed, policy liabilities related to the original policy that was replaced are immediately released, and policy liabilities are established for the new insurance contract. The policy reserves are evaluated based on the new policy features, and changes are recognized at the date of contract change/modification. For internal replacements that are substantially unchanged, no changes to the reserves are recognized. For modifications that are not integrated with the base policy, new coverage is recognized as a separately issued contract within the current cohort.

Unpaid Policy Claims

Unpaid policy claims primarily represent unpaid policy claims on the Company’s short-duration insurance contracts.

Unearned Premiums

Unearned premiums consist of unearned premiums and advance premiums.

Unearned premiums represent the portion of premium related to the unexpired coverage as of a balance sheet date and are deferred and recognized in net earned premiums when earned.

Advance premiums consist primarily of discounted advance premiums on deposit from policyholders in conjunction with their purchase of certain Aflac Japan limited-payment insurance products. Advanced premiums are deferred upon collection and recognized as earned premiums over the contractual premium payment period.

Other Policyholders' Funds

The other policyholders’ funds liability consists primarily of the fixed annuity line of business in Aflac Japan which has fixed benefits and premiums.

Reinsurance: The Company enters into reinsurance agreements in the normal course of business. For each reinsurance agreement, the Company determines if the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. Reinsurance premiums and benefits paid or provided are accounted for on bases consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums, benefits and acquisition costs are reported net of insurance ceded.

Income Taxes: Income tax provisions are generally based on pretax earnings reported for financial statement purposes, which differ from those amounts used in preparing the Company's income tax returns. Deferred income taxes are recognized for temporary differences between the financial reporting basis and income tax basis of assets and liabilities, based on enacted tax laws and statutory tax rates applicable to the periods in which the Company expects the temporary differences to reverse. The Company records deferred tax assets for tax positions taken based on its assessment of whether the tax position is more likely than not to be sustained upon examination by taxing authorities. A valuation allowance is established for deferred tax assets when it is more likely than not that an amount will not be realized.

Policyholder Protection Corporation and State Guaranty Association Assessments: In Japan, the government has required the insurance industry to contribute to a policyholder protection corporation. The Company recognizes a charge for its estimated share of the industry's obligation once it is determinable. The Company reviews the estimated liability for policyholder protection corporation contributions on an annual basis and reports any adjustments in Aflac Japan's expenses.

In the U.S., each state has a guaranty association that supports insolvent insurers operating in those states. The Company's policy is to accrue assessments when the entity to which the insolvency relates has met its state of domicile's statutory definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the


99
assessment is based is written. See Note 15 for further discussion of the guaranty fund assessments charged to the Company.

Treasury Stock: Treasury stock is reflected as a reduction of shareholders' equity at cost. The Company uses the weighted-average purchase cost to determine the cost of treasury stock that is reissued. The Company includes any gains and losses in additional paid-in capital when treasury stock is reissued.

Share-Based Compensation: The Company measures compensation cost related to its share-based payment transactions at fair value on the grant date, and the Company recognizes those costs in the financial statements over the vesting period during which the employee provides service in exchange for the award. The Company has made an entity-wide accounting policy election to estimate the number of awards that are expected to vest and the corresponding forfeitures.

Earnings Per Share: The Company computes basic earnings per share (EPS) by dividing net earnings by the weighted-average number of unrestricted shares outstanding for the period. Diluted EPS is computed by dividing net earnings by the weighted-average number of shares outstanding for the period plus the shares representing the dilutive effect of share-based awards.

Reclassifications: Certain reclassifications have been made to prior-year amounts to conform to current-year reporting classifications. These reclassifications had no impact on net earnings or total shareholders' equity.

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Accounting Standards Update (ASU) 2023-09 Income Taxes (Topic 740) - Improvements to Income Tax Disclosures

In December 2023, the FASB issued amendments that require enhanced income tax disclosures including (1) disclosure of specific categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures.

The Company adopted this guidance for the annual period beginning January 1, 2025 and elected a prospective implementation. The adoption of this guidance did not have an impact on the Company’s financial position or results of operations. See Note 10 for expanded disclosures required as a result of the amended guidance.

ASU 2023-07 Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures

In November 2023, the FASB issued amendments that add certain segment disclosures related to significant segment expenses and require that a public entity disclose the title and position of the Chief Operating Decision Maker (CODM) and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources.

The Company adopted this guidance for the annual period beginning January 1, 2024, and interim periods beginning January 1, 2025. The adoption of this guidance did not have an impact on the Company’s financial position or results of operations. See Note 2 for expanded disclosures required as a result of the amended guidance.

ASU 2023-02 Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method

In March 2023, the FASB issued amendments to permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense (benefit).

The Company early adopted this guidance on July 1, 2023. The adoption of this guidance did not have a significant impact on the Company's financial position, results of operations or disclosures.


100

ASU 2022-02 Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the FASB issued amendments that eliminated the accounting guidance for troubled debt restructurings (TDRs) for creditors, required enhanced disclosures for creditors about loan modifications when a borrower is experiencing financial difficulty, and required public business entities to include current-period gross write-offs in the vintage disclosure tables. As a result of eliminating the TDR guidance for creditors, all loan modifications will follow the existing loan refinancing or restructuring guidance.

The Company adopted this guidance on January 1, 2023 on a prospective basis. The adoption did not have an impact on the Company’s financial position or results of operations.

ASU 2018-12 Financial Services - Insurance: Targeted Improvements to the Accounting for Long-Duration Contracts, as clarified and amended by:
ASU 2019-09 Financial Services - Insurance: Effective Date
ASU 2020-11 Financial Services - Insurance: Effective Date and Early Application

In August 2018, the FASB issued amendments that significantly changed how insurers account for long-duration contracts. The Company adopted the standard on January 1, 2023 using a modified retrospective transition method which resulted in applying the amended guidance as of the beginning of the earliest period presented on the January 1, 2021 transition date (Transition Date). The modified retrospective transition method generally results in applying the guidance to contracts on the basis of existing carrying values as of the Transition Date. On the Transition Date, the Company calculated the ratio of the present value of expected future policy benefits and expenses less existing carrying values to the present value of expected future gross premiums (Transition Date NPR) using updated assumptions and the discount rate immediately before the Transition Date. The Company capped the Transition Date NPR at 100% for any cohorts with a Transition Date NPR greater than 100%. The Company calculated the LFPB using the Transition Date NPR (capped at 100% if required) and two different discount rates: (i) the discount rate used immediately before the Transition Date, and (ii) the discount rate determined by reference to the Transition Date market level yields for upper-medium grade (low credit risk) fixed income instruments (as of December 31, 2020). For cohorts with their Transition Date NPR capped at 100%, the Company recorded as an adjustment (decrease) to opening retained earnings any difference between the LFPB calculated using the discount rate immediately before the Transition Date and the existing carrying value as of the Transition Date. For all cohorts on the Transition Date, the Company recorded in accumulated other comprehensive income net of tax, the difference in the LFPB calculated using the two different discount rates (i.e., the discount rate used immediately before the Transition Date and the updated discount rate as of the Transition Date).

Upon adoption, the Company adjusted opening equity for the Transition Date impacts to accumulated other comprehensive income and retained earnings and adjusted prior periods then presented (years 2021 and 2022) following the updated standard. Based upon the modified retrospective transition method, the Transition Date impact from adoption resulted in a decrease in accumulated other comprehensive income of approximately $18.6 billion and a decrease in retained earnings (RE) of approximately $0.3 billion.

The adoption of ASU 2018-12 did not have an impact on the Company's balance for deferred policy acquisition costs upon adoption.

In conjunction with the adoption of ASU 2018-12, the Company changed its practice of recording the change in the deferred profit liability on products with limited-payment features from the benefits and claims, net line item to the net earned premiums line item in the consolidated statements of earnings. This reclassification had no impact on net earnings. The change in presentation has been made for all comparative periods presented.

Accounting Pronouncements Pending Adoption

ASU 2024-03 Income Statement (Topic 220) - Disaggregation of Income Statement Expenses

In November 2024, the FASB issued amendments that require disaggregated disclosure, in the notes to the financial statements, of specified information about certain costs and expenses including (1) the amounts of employee compensation, depreciation, and intangible asset amortization; (2) certain expense, gain, or loss amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements; (3) qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated


101
quantitatively, and (4) the total amount of selling expenses and, in annual reporting periods, the Company’s definition of selling expenses.

The amendments are effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The adoption of this guidance has no impact on the Company’s financial position or results of operations. The Company is evaluating the impact of adoption on its disclosures.

Recent accounting guidance not discussed above is not applicable, did not have, or is not expected to have a material impact to the Company's business.

2.    BUSINESS SEGMENT INFORMATION AND SELECTED FOREIGN CURRENCY TRANSLATION ITEMS
The Company consists of two reportable insurance business segments: Aflac Japan and Aflac U.S., both of which sell supplemental health and life insurance. In addition, the Parent Company, other operating business units that are not individually reportable, reinsurance activities, including internal reinsurance activity with Aflac Re, and other business activities not included in Aflac Japan or Aflac U.S., as well as intercompany eliminations, are included in Corporate and other. The Company does not allocate corporate overhead expenses to business segments.

The Company’s reportable segments are regularly reviewed by the Company's CODM, Senior Executive Vice President and Chief Financial Officer, in deciding how to allocate resources and in assessing performance. The Company's CODM reviews and approves the annual budget and operating forecast, which allocates resources to segments and serves as a key benchmark for tracking performance and accountability of each segment's operating results. The Company’s CODM evaluates the performance of the segments using, in comparison to the annual budget, operating forecast and historical results, a financial performance measure called pretax adjusted earnings and believes this financial performance measure to be vitally important for understanding the underlying profitability drivers and trends of the Company’s insurance business.
•Pretax adjusted earnings are adjusted revenues less benefits and adjusted expenses. The adjustments to both revenues and expenses account for certain items that are outside management's control because they tend to be driven by general economic conditions and events or are related to infrequent activities not directly associated with insurance operations. The Company excludes income taxes related to operations to arrive at pretax adjusted earnings.
◦Adjusted revenues are U.S. GAAP total revenues excluding net investment gains and losses, except for amortized hedge costs/income related to foreign currency exposure management strategies and net interest income/expense from derivatives associated with certain investment strategies, which are reclassified from net investment gains (losses) and included in adjusted earnings as a component of adjusted net investment income when analyzing operations. 
◦Adjusted expenses are U.S. GAAP total acquisition and operating expenses including the impact of interest from derivatives associated with notes payable but excluding any non-recurring or other items not associated with the normal course of the Company’s insurance operations and that do not reflect the Company’s underlying business performance.

Aflac Japan's adjusted revenues accounted for 53% of the Company's total adjusted revenues in 2025, compared with 55% in 2024 and 60% in 2023. The percentage of the Company's total assets attributable to Aflac Japan was 76% at December 31, 2025, compared with 77% at December 31, 2024.

Investment Concentrations

The Company's process for investing in credit-related investments begins with an independent approach to underwriting each issuer's fundamental credit quality. The Company evaluates independently those factors that it believes could influence an issuer's ability to make payments under the contractual terms of the Company's instruments. This includes a thorough analysis of a variety of items including the issuer's country of domicile (including political, legal, and financial considerations); the industry in which the issuer competes (with an analysis of industry structure, end-market dynamics, and regulation); company specific issues (such as management, assets, earnings, cash generation, and capital needs); and contractual provisions of the instrument (such as financial covenants and position in the capital structure). The Company further evaluates the investment considering broad business and portfolio management objectives, including asset/liability needs, portfolio diversification, and expected income.

Analysis of Securities in Unrealized Loss Positions

The unrealized losses on the Company's available-for-sale securities have been primarily related to general market factors such as changes in interest rates, foreign exchange rates, and/or the levels of credit spreads rather than specific concerns with the issuer's ability to pay interest and repay principal.

For available-for-sale securities in an unrealized loss position, the Company performs detailed analyses to identify whether the drivers of the decline in fair value are due to general market factors, such as the recent rise in interest rates, or due to credit-related factors. Identifying the drivers of the declines in fair value helps to align and allocate the Company's resources to the review and monitoring of securities with real credit-related concerns that could impact ultimate collection of principal and interest. For any significant declines in fair value determined to be non-interest rate or market-related, the Company performs a more focused review of the related issuers' specific credit profile.

For corporate issuers, the Company evaluates their assets and business profile, including industry dynamics and competitive positioning, financial statements and other available financial data. For non-corporate issuers, the Company analyzes all sources of credit support, including issuer-specific factors. The Company utilizes information available in the public domain and, for certain private placement issuers, from consultations with the issuers directly. The Company also considers ratings from Nationally Recognized Statistical Rating Organizations (NRSROs), as well as the specific characteristics of the security it owns including seniority in the issuer's capital structure, covenant protections, or other relevant features. From these reviews, the Company evaluates the issuers' continued ability to service the Company's investment through payment of interest and principal.


113
Assuming no credit-related factors develop and excluding any impact resulting from fluctuations in the yen/dollar exchange rate, unrealized gains and losses on available-for-sale securities are expected to diminish as investments near maturity. Based on its credit analysis, the Company believes that the issuers of its available-for-sale securities in the sectors presented in the table above have the ability to service their obligations to the Company. Further, the Company does not intend to sell the investments and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases, which may be at maturity.

However, if the Company identifies certain available-for-sale securities where the amortized cost basis exceeds the present value of the cash flows expected to be collected due to credit-related factors, an allowance for credit losses is recognized. Based on an evaluation of its securities currently in an unrealized loss position, the Company has determined that those securities should not have an allowance for credit losses as of December 31, 2025. Refer to the Allowance for Credit Losses Methodology section below for additional information.

As of December 31, 2025 and 2024, the Company had an immaterial amount of fixed maturity securities on nonaccrual status.

CMLs and TREs are secured by properties entirely within the U.S. (with the largest concentrations in California (22%), Texas (13%) and Florida (8%)). MMLs are issued only to companies domiciled within the U.S. and Canada.

Transitional Real Estate Loans

TREs are relatively short-term floating rate commercial mortgage loans that are secured by a first lien on the property. These loans provide funding for properties undergoing a change in their physical characteristics and/or economic profile and do not typically require any principal repayment prior to the maturity date.



114
As of December 31, 2025, the Company had $140 million in outstanding commitments to fund TREs. These commitments are contingent on the final underwriting and due diligence to be performed.

Commercial Mortgage Loans

CMLs are typically fixed rate loans on commercial real estate with partial repayment of principal over the life of the loan with the remaining outstanding principal being repaid upon maturity. This loan portfolio is generally considered higher quality investment grade loans.

Middle Market Loans

MMLs are typically first lien senior secured cash flow loans to small to mid-size companies for working capital, refinancing, acquisition, and recapitalization. These loans are generally considered to be below investment grade.

As of December 31, 2025, the Company had commitments of approximately $704 million to fund future MMLs. These commitments are contingent upon the availability of MMLs that meet the Company's underwriting criteria.

Other Loans

Other loans are primarily infrastructure loans. Infrastructure loans are typically senior secured, financing operating portfolios of renewable and conventional energy generation assets characterized by predictable, often contractual cash flows for loan repayment. The infrastructure loan portfolio weighted average rating is investment grade.

As of December 31, 2025, the Company had commitments of approximately $1 million to fund future other loans. These commitments are contingent upon the availability of other loans that meet the Company's underwriting criteria.

For each of the years ended December 31, 2025 and 2024, the Company recognized $2 million of interest income on loans that were on nonaccrual status. For the year ended December 31, 2023, the Company recognized no interest income on loans that were on nonaccrual status. Of these loans, TREs with an amortized cost of $30 million and $140 million had no credit loss allowance as of December 31, 2025 and December 31, 2024, respectively, because these loans are collateral dependent assets for which the estimated fair values of the collateral were in excess of amortized

cost. As of December 31, 2025 and 2024, MMLs with an amortized cost of $36 million and $5 million, respectively, were on nonaccrual status without an allowance for credit losses.

Loan Modifications to Borrowers Experiencing Financial Difficulties

The Company granted certain loan modifications to borrowers experiencing financial difficulty during 2025, 2024 and 2023. The types of modifications granted may include interest rate reductions, principal forgiveness, other-than-insignificant payment delays, term extensions or a combination of these types of modifications. The amount, timing, and extent of modifications granted are considered in determining any allowance for credit loss recorded.

Loans that have both been modified and are paid or written off during the period, resulting in an amortized cost balance of zero at the end of the period, are not included in the disclosures below.

The following tables present the amortized cost basis of modified loans to borrowers experiencing financial difficulty and the financial effect of the modifications, disaggregated by loan classification and type of modification, for the years ended December 31.

The Company closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. Loans that were granted a modification in the past 12 months, as of December 31, 2025 and 2024, and subsequently defaulted in the years ended December 31, 2025 and 2024, were immaterial. There were no modified loans to borrowers experiencing financial difficulties in the past 12 months, as of December 31, 2023, that subsequently defaulted in the year ended December 31, 2023.

As of December 31, 2025, the Company had $15 million of outstanding commitments to lend additional funds to borrowers experiencing financial difficulty that were granted a loan modification, compared with $14 million as of December 31, 2024.

As of December 31, 2025, the Company identified TREs with an amortized cost of $137 million in anticipation of potential foreclosure or deed in lieu of foreclosure transactions. As of December 31, 2025, the Company established an allowance for credit losses of $45 million related to these loans.


117
As of December 31, 2025, the Company’s held-to-maturity portfolio includes Japan Government and Agency securities with an amortized cost of $15.3 billion that meet the requirements for zero-credit-loss expectation and therefore have been excluded from the measurement of the allowance for credit losses.

Allowance for Credit Losses Methodology

Available-for-sale Securities

For available-for-sale securities, the Company evaluates estimated credit losses only when the amortized cost basis exceeds the present value of the cash flows expected to be collected due to credit related factors. The Company’s methodology for estimating an allowance for credit losses for available-for-sale securities utilizes the discounted cash flow model, based on past events, current market conditions and future economic conditions, as well as industry analysis and credit ratings of the securities. In addition, the Company evaluates the specific issuer’s probability of default and expected recovery of its position in the event of default based on the underlying financial condition and assets of the borrower as well as seniority and/or security of other debt holders in the issuer when developing management’s best estimate of expected cash flows.

An investment in an available-for-sale security may be impaired if the fair value falls below amortized cost. The Company regularly reviews its available-for-sale portfolio for declines in fair value. The Company's available-for-sale impairment model focuses on the ultimate collection of the cash flows from its investments and whether the Company has the intent to sell or if it is more likely than not the Company would be required to sell the security prior to recovery of its amortized cost. The determination of the amount of impairments under this model is based upon the Company's periodic evaluation and assessment of known and inherent risks associated with the respective securities. Such evaluations and assessments are revised as conditions change and new information becomes available.

When determining the Company's intention to sell a security prior to recovery of its amortized cost basis, the Company evaluates facts and circumstances such as, but not limited to, future cash flow needs, decisions to reposition its security portfolio, and risk profile of individual investment holdings. The Company performs ongoing analyses of its liquidity needs, which includes cash flow testing of its policy liabilities, debt maturities, projected dividend payments, and other cash flow and liquidity needs.

Held-to-maturity Securities, Loan Receivables, and Loan Commitments

The Company calculates its allowance for credit losses for held-to-maturity securities, loan receivables and loan commitments by grouping assets with similar risk characteristics when there is not a specific expectation of a loss for an individual asset. For held-to-maturity securities, MMLs, and MML commitments, the Company groups assets by industry, country, and key credit quality indicators. The Company groups CMLs and TREs and respective loan commitments by property type, property location and key credit quality indicators. On a quarterly basis, CMLs and TREs within a portfolio segment that share similar risk characteristics are pooled for the allowance calculation. On an ongoing basis, TREs, CMLs and other loans with dissimilar risk characteristics (i.e., loans with significant declines in credit quality), such as collateral dependent mortgage loans (i.e., when the borrower is experiencing financial difficulty, including when foreclosure is probable), are evaluated individually for credit loss.

The allowance for credit losses for held-to-maturity securities and loan receivables is estimated using a probability-of-default (PD) / loss-given-default (LGD) method, discounted for the time value of money. For held-to-maturity securities, available-for-sale securities, and loan receivables, the Company includes the change in present value due to the passage of time in the change in the allowance for credit losses. The Company’s methodology for estimating credit losses utilizes the contractual maturity date of the financial asset, adjusted when necessary to reflect the expected timing of repayment (such as prepayment options, renewal options, call options, or extension options). The Company applies reasonable and supportable forecasts of macroeconomic variables that impact the determination of PD / LGD over a two-year period for held-to-maturity securities and MMLs. The Company reverts to historical loss information over one year, following the two-year forecast period.

For the CML and TRE portfolio, the Company applies reasonable and supportable forecasts of macroeconomic variables as well as national and local real-estate market factors to estimate future credit losses where the market factors revert back to historical levels over time with the period being dependent on current market conditions, projected market conditions and difference in the current and historical market levels for each factor.

For off-balance sheet credit exposure primarily attributable to loan commitments that are not unconditionally cancellable, the Company considers the contractual period of exposure to credit risk, the likelihood that funding will occur, the risk of


118
loss, and the current conditions and expectations of future economic conditions to estimate the allowance for credit losses.

The Company continuously monitors the estimation methodology, due to changes in portfolio composition, changes in underwriting practices and significant events or conditions and makes adjustments as necessary.

Key Credit Quality Indicators

The Company’s key credit quality indicators used in the grouping of assets are outlined by investment type below.

•For held-to-maturity securities and MMLs, the Company’s key credit quality indicator is credit ratings. The Company’s held-to-maturity portfolio is composed of investment grade securities that are senior unsecured instruments, while its MMLs generally have below-investment-grade ratings but are typically senior secured instruments. The Company monitors the credit ratings periodically, but not less frequently than quarterly.

•For TREs, the Company’s key credit quality indicators include performance of the loan and loan-to-value (LTV), which is calculated by dividing the current outstanding loan balance by the estimated property value, primarily using values at origination. Given that TREs involve properties undergoing a repositioning of their commercial profile, LTV provides the most insight into the credit risk of the loan. The Company monitors the performance of the loans periodically, but not less frequently than quarterly. The monitoring process also focuses on higher risk loans, which include those that are delinquent or for which foreclosure or deed in lieu of foreclosure is anticipated.

•For CMLs, the Company’s key credit quality indicators include LTV and debt service coverage ratios (DSCR). DSCR is the most recently available net operating income of the underlying property compared to the required debt service of the loan.

•For other loans, the Company's key credit quality indicator is credit ratings. The Company monitors these credit ratings periodically, but not less frequently than quarterly.

The following tables present as of December 31, 2025 the amortized cost basis of TREs, CMLs, MMLs, and other loans by year of origination and key credit quality indicator.

As of December 31, 2025 and 2024, all REO was classified as held-and-used for the production of income. Depreciation expense on REO was $29 million, $13 million, and an immaterial amount for the years ended December 31, 2025, 2024, and 2023, respectively. Additionally, as of December 31, 2025 and 2024, accumulated depreciation on REO was $41 million and $14 million, respectively.

The Company had $3.0 billion and $2.8 billion in outstanding commitments to fund investments in limited partnerships, which included $2.1 billion and $2.1 billion of unfunded commitments related to VIEs that are non-consolidated as of December 31, 2025 and 2024, respectively.


120
Variable Interest Entities

In the normal course of its activities, the Company invests in legal entities that are VIEs. The Company's variable interests in VIEs are limited to the debt and equity instruments issued by them. With the exception of commitments to limited partnerships and to certain loan investments made in the normal course of business, the Company has not provided any direct or contingent obligations to fund the limited activities of these VIEs, or support related to the limited activities of these VIEs, and does not have any intention to do so in the future, nor has it provided any direct or indirect financial guarantees.

The Company's risk of loss related to its interests in any of its VIEs is limited to the carrying value of the related investments, and in certain cases, to any unfunded commitments held in the VIE.

For those VIEs other than certain unit trust structures, the Company's involvement is passive in nature.

VIEs - Consolidated

If the Company determines that it is the VIE’s primary beneficiary, it consolidates the VIE. Creditors or beneficial interest holders of VIEs where the Company is the primary beneficiary have no recourse to the general credit of the Company except to the extent of the unfunded commitments referenced above, as the Company’s obligation to each VIE is limited to the amount of its committed investment.

The following table presents the carrying value and balance sheet caption in which the assets and liabilities of consolidated VIEs are reported as of December 31.

The Company is the sole investor in the consolidated VIEs listed in the table above. The Company invests in fixed maturity securities issued by VIEs that in turn hold U.S. dollar-denominated fixed maturity securities coupled with foreign currency swap agreements. The weighted-average lives of the Company's investments in these VIEs are very similar to the underlying collateral held by these VIEs. The activities of these VIEs are limited to holding invested assets and foreign currency swaps and utilizing the cash flows from these securities to service the VIEs' debt. Neither the Company nor any of its creditors are able to obtain the underlying collateral of these VIEs unless there is an event of default or other specified event. The Company is not a direct counterparty to the foreign currency swap contracts and has no control over them. The Company's loss exposure to these VIEs is limited to its original investment. These consolidated VIEs do not rely on outside or ongoing sources of funding to support their activities beyond the underlying collateral and foreign currency swap contracts, if applicable. The underlying collateral assets and funding of these consolidated VIEs are generally static in nature.


121
Investments in Unit Trust Structures

The Company also utilizes unit trust structures in Aflac Japan to invest in various asset classes, which include CMLs, MMLs, TREs, other loans and limited partnerships. As the sole investor of these VIEs, the Company is required to consolidate these trusts. The limited partnership investments are comprised of private equity and real estate. The Company's loss exposure to these VIEs is limited to its original investments, together with any unfunded portion of the Company's commitments made in the normal course of business to fund certain loan investments and limited partnership investments, as described in the Commercial Mortgage and Other Loans and Other Investments sections of this note. Excluding these commitments, the Company does not provide financial or other support to consolidated VIEs.

VIEs - Not Consolidated

The table below presents the carrying value and balance sheet caption in which the Company's investments in VIEs that are not consolidated are reported as of December 31.

(1) Consists entirely of alternative investments in limited partnerships

Certain investments in VIEs that the Company is not required to consolidate are investments that are in the form of debt obligations issued by the VIEs. These fixed maturity securities include structured securities, primarily asset-backed securities. The Company's involvement in the related VIEs is limited to that of a passive investor in asset-backed securities issued by the VIEs. The Company also invests in fixed maturity securities issued by VIEs that are the primary financing vehicles used by their corporate sponsors to raise financing in the capital markets. The variable interests created by these VIEs are principally or solely a result of the debt instruments issued by them. The Company does not have the power to direct the activities that most significantly impact the entity's economic performance, nor does it have the obligation to absorb losses of the VIE entity or the right to receive benefits from the entity that could be significant to the entity. As such, the Company is not the primary beneficiary of these VIEs and therefore is not required to consolidate them.

The Company also holds equity investments in limited partnerships that have been determined to be VIEs. These partnerships primarily invest in private equity and real estate funds. The Company’s maximum exposure to loss on these investments is limited to the amount of its investment and any unfunded commitments. As described in the Other Investments section of this note, the Company makes commitments to fund partnership investments in the normal course of business. Excluding these commitments, the Company did not provide financial or other support to unconsolidated VIEs. The Company is not the primary beneficiary of these VIEs and is therefore not required to consolidate them. The Company classifies these investments as other investments in the consolidated balance sheets.

In connection with securities lending, in addition to cash collateral received, the Company received from counterparties securities collateral of $2.2 billion and $3.0 billion at December 31, 2025, and 2024, respectively, which may not be sold or re-pledged, unless the counterparty is in default. Such securities collateral is not reflected in the consolidated balance sheets.

The Company did not have any repurchase agreements or repurchase-to-maturity transactions outstanding as of December 31, 2025 and 2024, respectively.

Certain fixed maturity securities can be pledged as collateral as part of derivative transactions, or pledged to support state deposit requirements on certain investment programs. For additional information regarding pledged securities related to derivative transactions, see Note 4.

At December 31, 2025, fixed maturity securities with a fair value of $20 million were on deposit with regulatory authorities in the U.S. (including U.S. territories). The Company retains ownership of all securities on deposit and receives the related investment income.

For general information regarding the Company's investment accounting policies, see Note 1.

Foreign currency forwards and options are executed for Aflac Japan in order to hedge the foreign currency exchange risk on the carrying value of certain U.S. dollar-denominated investments. The average maturity of these forwards and options can change depending on factors such as market conditions and types of investments being held. In situations where the maturity of the forwards and options is shorter than the underlying investment being hedged, the Company may enter into new forwards and options near maturity of the existing derivative in order to continue hedging the underlying investment. In forward transactions, Aflac Japan agrees with another party to buy a fixed amount of Japanese yen and sell a corresponding amount of U.S. dollars at a specified future date. The Company also uses one-sided foreign currency put options to mitigate the settlement risk on U.S. dollar-denominated assets related to extreme foreign exchange rate changes.

From time to time, Aflac Japan also executes foreign currency option transactions in a collar strategy, where Aflac Japan agrees with another party to simultaneously purchase put options and sell call options. In the purchased put transactions, Aflac Japan obtains the option to buy a fixed amount of Japanese yen and sell a corresponding amount of U.S. dollars at a specified future date. In the sold call transactions, Aflac Japan agrees to sell a fixed amount of Japanese yen and buy a corresponding amount of U.S. dollars at a specified future date. The combination of purchasing the put option and selling the call option results in no net premium being paid (i.e. a costless or zero-cost collar).

From time to time, the Company may also enter into foreign currency forwards and options to hedge the foreign currency exchange risk associated with the net investment in Aflac Japan. In these forward transactions, the Company agrees with another party to buy a fixed amount of U.S. dollars and sell a corresponding amount of Japanese yen at a specified price at a specified future date. In the option transactions, the Company may use a combination of foreign currency options to protect expected future cash flows by simultaneously purchasing Japanese yen put options (options that protect against a weakening Japanese yen) and selling Japanese yen call options (options that limit participation in a strengthening Japanese yen). The combination of these two actions create a zero-cost collar. Additionally, the Company enters into purchased options to hedge cash flows from the net investment in Aflac Japan.

The Company enters into foreign currency swaps pursuant to which it exchanges an initial principal amount in one currency for an initial principal amount of another currency, with an agreement to re-exchange the principal amounts at a future date. There may also be periodic exchanges of payments at specified intervals based on the agreed upon rates and notional amounts. Foreign currency swaps are used primarily in the consolidated VIEs held by Aflac Japan to convert foreign-denominated cash flows to Japanese yen in order to minimize cash flow fluctuations. The Company also uses foreign currency swaps to economically hedge the foreign currency exchange risk on certain fixed maturity securities denominated in other foreign currencies held by Aflac Japan, as well as to economically convert certain of its U.S. dollar-denominated senior note and subordinated debenture principal and interest obligations into Japanese yen-denominated obligations.


124
The Company also uses foreign currency forwards to economically hedge the foreign currency exchange risk on certain variable-rate investments denominated in other foreign currencies held by Aflac Japan.

In order to reduce investment income volatility from its variable-rate investments, the Company enters into receive–fixed, pay–floating interest rate swaps. These derivatives are cleared and settled through a central clearinghouse.

Swaptions are used to mitigate the adverse impact resulting from significant changes in the fair value of U.S. dollar-denominated available-for-sale securities due to fluctuation in interest rates. In a payer swaption, the Company pays a premium to obtain the right, but not the obligation, to enter into a swap contract where it will pay a fixed rate and receive a floating rate. Interest rate swaption collars are combinations of two swaption positions. In order to maximize the efficiency of the collars while minimizing cost, a collar strategy is used whereby the Company purchases a long payer swaption (the Company purchases an option that allows it to enter into a swap where the Company will pay the fixed rate and receive the floating rate of the swap) and sells a short receiver swaption (the Company sells an option that provides the counterparty with the right to enter into a swap where the Company will receive the fixed rate and pay the floating rate of the swap). The combination of purchasing the long payer swaption and selling the short receiver swaption results in no net premium being paid (i.e. a costless or zero-cost collar).

Bond purchase commitments result from repackaged bond structures that are consolidated VIEs whereby there is a delay in the trade date and settlement date of the bond within the structure to ensure completion of all necessary legal agreements to support the consolidated VIE that issues the repackaged bond. Since the Company has a commitment to purchase the underlying bond at a specified price, the agreement meets the definition of a derivative. The fair value of the derivative is derived based on the current market value of the bond compared to the fixed purchase price to be paid on the settlement date.

Derivative Balance Sheet Classification
The table below summarizes the balance sheet classification of the Company's derivative instruments at fair value, at December 31. The fair value amounts presented exclude income accruals. Derivative assets are included in other assets while derivative liabilities are included in other liabilities in the consolidated balance sheets. The notional amount of derivative contracts represents the basis upon which pay or receive amounts are calculated and are not reflective of exposure or credit risk.

Cash Flow Hedge

The Company designates and accounts for certain foreign currency swaps as cash flow hedges when they meet the requirements for hedge accounting. For certain variable-rate U.S. dollar-denominated available-for-sale securities held by Aflac Japan via consolidated VIEs, foreign currency swaps are used to swap the U.S. dollar variable rate interest and principal payments to fixed rate Japanese yen interest and principal payments. The remaining maximum length of time over which these cash flows are hedged is approximately one year.
Fair Value Hedge
The Company designates and accounts for certain foreign currency forwards, options, and interest rate swaptions as fair value hedges when they meet the requirements for hedge accounting.
Foreign currency forwards and options hedge the foreign currency exchange risk associated with certain U.S. dollar-denominated available-for-sale securities held by Aflac Japan. For these derivatives and the related hedged items, gains and losses included in the assessment of hedge effectiveness are included in current earnings.

The change in the fair value of the foreign currency forwards related to changes in the difference between the spot rate and the forward price, and the change in fair value of the foreign currency option related to the time value of the option, are excluded from the assessment of hedge effectiveness and are included in current earnings.

Interest rate swaptions hedge the interest rate risk associated with certain U.S. dollar-denominated available-for-sale securities held by Aflac Japan. Gains and losses associated with these derivatives and included in the assessment of hedge effectiveness, premium amortization and time value amortization while the hedge items are still outstanding, are included in current earnings. If the interest rate swaption is terminated but the hedged item is still outstanding, the amortization of the disposal amount of the interest rate swaption is included in current earnings over the remaining life of the hedged items. When the related hedged items are redeemed, the time value gains and losses for the interest rate swaptions are included in current earnings, which is consistent with the accounting for the impact of the hedged item.

The change in the fair value of interest rate swaptions related to the time value of the swaption is excluded from the assessment of hedge effectiveness and is included in the consolidated statements of comprehensive income (loss) and amortized into earnings over its legal term.
Fair Value Hedging Relationships
The following table presents the gains and losses on derivatives and the related hedged items in fair value hedging relationships for the year ended December 31, 2023. The Company had no fair value hedges during the years ended December 31, 2025 and 2024.

Net Investment Hedge

The Company's investment in Aflac Japan is affected by changes in the foreign exchange rate. To mitigate this exposure, the Parent Company designated some of its Japanese yen-denominated liabilities (see Note 9) as non-derivative net investment hedges and certain foreign currency forwards and options as derivative net investment hedges of the foreign currency exchange risk associated with the Company's net investment in Aflac Japan.

The Company's net investment hedge was effective during the years ended December 31, 2025, 2024 and 2023.

Non-qualifying Strategies

The Company uses foreign currency swaps to economically hedge the foreign currency exchange risk associated with certain investments denominated in other foreign currencies held by Aflac Japan.

For the Company's derivative instruments in consolidated VIEs that do not qualify for hedge accounting, changes in fair value are reported in current earnings. The gain or loss in earnings includes amounts attributable to the derivatives in those investment structures. While the change in fair value of the derivative instrument is reported in current earnings, the change in the fair value of the available-for-sale securities associated with these instruments is included in accumulated other comprehensive income.

The Company uses foreign currency forwards and options to economically hedge the foreign currency exchange risk associated with certain U.S. dollar-denominated loan receivables held by Aflac Japan. These arrangements are not designated as accounting hedges because the foreign currency remeasurement gains and losses associated with the loan receivables substantially offsets gains and losses from foreign currency forwards in current period earnings.

Additionally, the Company uses foreign currency forwards to economically hedge the foreign currency exchange risk associated with certain U.S. dollar-denominated available-for-sale securities and certain investments denominated in other foreign currencies held by Aflac Japan.

The Company uses interest rate swaps to economically convert the variable rate investment income to a fixed rate on certain variable-rate investments.

The Parent Company had cross-currency swap agreements related to certain of its U.S. dollar-denominated senior notes to effectively convert interest and principal on the notes from U.S. dollar to Japanese yen. These swaps matured in 2025. Changes in the fair value of these swaps were reported in earnings in the period where they occurred.

Credit Risk Assumed through Derivatives

For the foreign currency swaps associated with the Company's VIE investments for which it is the primary beneficiary, the Company bears the risk of loss due to counterparty default even though it is not a direct counterparty to those contracts.

The Company is a direct counterparty to the foreign currency swaps that it has entered into in connection with certain of its senior notes and subordinated debentures; foreign currency forwards; and foreign currency options, and therefore the Company is exposed to credit risk in the event of nonperformance by the counterparties in those contracts. The risk of counterparty default for the Company's foreign currency swaps, certain foreign currency forwards, and foreign currency options is mitigated by collateral posting requirements that counterparties to those transactions must meet.

As of December 31, 2025, all of the Company's derivative agreement counterparties were investment grade.

The Company engages in over-the-counter (OTC) bilateral derivative transactions directly with unaffiliated third parties under International Swaps and Derivatives Association, Inc. (ISDA) agreements and other documentation. Most of the ISDA agreements also include Credit Support Annexes (CSAs) provisions, which generally provide for two-way collateral postings at the first dollar of exposure. The Company mitigates the risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value while generally requiring that collateral be posted at the outset of the transaction. In addition, a significant portion of the derivative transactions have provisions that give the counterparty the right to terminate the transaction upon a downgrade of the Company's financial strength rating. The actual amount of payments that the Company could be required to make depends on market conditions, the fair value of outstanding affected transactions, and other factors prevailing at and after the time of the downgrade.

The Company also engages in OTC cleared derivative transactions through regulated central clearing counterparties. These positions are marked to market and margined on a daily basis (both initial margin and variation margin), and the Company has minimal exposure to credit-related losses in the event of nonperformance by counterparties to these derivatives.

Collateral posted by the Company to third parties for derivative transactions can generally be repledged or resold by the counterparties. The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a net liability position by counterparty was approximately $861 million and $804 million as of December 31, 2025 and 2024, respectively. If the credit-risk-related contingent features underlying these agreements had been triggered on December 31, 2025, the Company estimates that it would be required to post a maximum of $669 million of additional collateral to these derivative counterparties. The Company is generally allowed to sell or repledge collateral obtained from its derivative counterparties, although it does not typically exercise such rights. See the Offsetting tables below for collateral posted or received as of the reported balance sheet dates.

Offsetting of Financial Instruments and Derivatives

Most of the Company's derivative instruments are subject to enforceable master netting arrangements that provide for the net settlement of all derivative contracts between the Parent Company or its subsidiaries and the respective counterparty in the event of default or upon the occurrence of certain termination events. Collateral support agreements with the master netting arrangements generally provide that the Company will receive or pledge financial collateral at the first dollar of exposure.

The Company has securities lending agreements with unaffiliated financial institutions that post collateral to the Company in return for the use of its fixed maturity and public equity securities (see Note 3). When the Company has entered into securities lending agreements with the same counterparty, the agreements generally provide for net settlement in the event of default by the counterparty. This right of set-off allows the Company to keep and apply collateral received if the counterparty failed to return the securities borrowed from the Company as contractually agreed.

The tables below summarize the Company's derivatives and securities lending transactions as of December 31, and as reflected in the tables, in accordance with U.S. GAAP, the Company's policy is to not offset these financial instruments in the consolidated balance sheets.

5.    FAIR VALUE MEASUREMENTS
Fair Value Hierarchy

U.S. GAAP specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. These two types of inputs create three valuation hierarchy levels, as follows:

•Level 1 valuations reflect quoted market prices for identical assets or liabilities in active markets.
•Level 2 valuations reflect quoted market prices for similar assets or liabilities in an active market, quoted market prices for identical or similar assets or liabilities in non-active markets or model-derived valuations in which all significant valuation inputs are observable in active markets.
•Level 3 valuations reflect valuations in which one or more of the significant inputs are not observable in an active market.

Fair Value of Financial Instruments

Fixed maturity and equity securities

The fair values of the Company's public fixed maturity securities are generally based on prices provided by third-party pricing vendors. The Company utilizes internally generated valuations or broker quotes for privately issued fixed maturity securities or fixed maturity securities where there is no price available from a third-party pricing vendor.

The fair values of the Company's public equity securities are generally based on price quotes, including quoted market prices readily available from independent public exchange markets or established security dealer associations. The Company determines the fair values of privately issued equity securities using the following approaches or techniques:

•price quotes and valuations from third-party pricing vendors,
•in-house valuations, and
•non-binding price quotes the Company obtains from outside brokers.

The pricing data and market quotes the Company obtains from outside sources, including third-party pricing services, are reviewed internally for reasonableness. If a fair value appears unreasonable, the Company will re-examine the inputs and assess the reasonableness of the pricing data with the provider. Additionally, the Company may compare the inputs to relevant market indices and other performance measurements. Based on management's analysis, the valuation is confirmed or may be revised if there is evidence of a more appropriate estimate of fair value based on available market data. The Company has performed verification of the inputs and calculations in any valuation models, including independent validations and back testing, to confirm that the valuations represent reasonable estimates of fair value. For the periods presented, the Company has not adjusted the quotes or prices it obtains from the pricing services and brokers it uses.

For internally generated valuations, the Company utilizes valuation models developed by a third-party pricing vendor. The models and associated processes and controls are executed by Company personnel.


137
These models are discounted cash flow valuation models but also use information from related markets, specifically public bond markets and the credit default swap (CDS) market, to estimate expected cash flows. The models take into consideration any unique characteristics of the securities and make various adjustments to arrive at an appropriate issuer-specific loss adjusted credit curve using the most appropriate comparable security(ies) of the issuer and issuer-specific CDS spreads. This credit curve is then used with the relevant recovery rates to estimate expected cash flows and modeling of additional features, including illiquidity adjustments, if necessary, to price the security by discounting those loss adjusted cash flows. In cases where a credit curve cannot be developed from market information for the specific issuer, the valuation methodology takes into consideration other market observable inputs, including:

•the most appropriate comparable security(ies) of a guarantor and/or parent
•CDS spreads of a guarantor and/or parent
•bonds of comparable issuers with similar characteristics such as rating, geography, or sector
•CDS spreads of an appropriate index or of comparable issuers with similar characteristics such as rating, geography, or sector
•bond indices that are comparative in rating, industry, maturity, and region.

The following is a discussion of the determination of fair value of the Company's remaining financial instruments.

Derivatives

The Company uses derivative instruments to manage the risk associated with certain assets. However, the derivative instrument may not be classified in the same fair value hierarchy level as the associated asset. The significant inputs to pricing derivatives are generally observable in the market or can be derived from observable market data. When these inputs are observable, the derivatives are classified as Level 2.

The Company uses present value techniques to value non-option based derivatives. It also uses option pricing models to value option based derivatives. Key inputs are as follows:
Instrument TypeLevel 2
Interest rate derivatives
Swap yield curves
Basis curves
Interest rate volatility (1)
Foreign exchange rate derivatives - Non-VIEs (forwards, swaps and options)
Foreign currency forward rates
Swap yield curves
Basis curves
Foreign currency spot rates
Foreign cross-currency basis curves
Foreign currency volatility (1)
Foreign exchange rate derivatives - VIEs (swaps)
Foreign currency spot rates
Swap yield curves
Credit default swap curves
Basis curves
Recovery rates
Foreign currency forward rates
Foreign cross-currency basis curves
(1) Option-based only

The fair values of the foreign currency forwards and options are based on observable market inputs, therefore they are classified as Level 2.



142
The Parent Company had cross-currency swap agreements related to certain of its U.S. dollar-denominated senior notes to effectively convert a portion of the interest on the notes from U.S. dollar to Japanese yen. These swaps matured in March 2025. Their fair values were based on observable market inputs; therefore, they were classified as Level 2.

To determine the fair value of its interest rate derivatives, the Company uses inputs that are generally observable in the market or can be derived from observable market data. Interest rate swaps are cleared trades. In a cleared swap contract, the clearinghouse provides benefits to the counterparties similar to contracts listed for investment traded on an exchange since it maintains a daily margin to mitigate counterparties' credit risk. These derivatives are priced using observable inputs, accordingly, they are classified as Level 2.

For derivatives associated with VIEs where the Company is the primary beneficiary, the Company is not the direct counterparty to the swap contracts. Nevertheless, the Company has full transparency into the contracts to properly value the swaps for reporting purposes. For these derivatives, the Company utilizes valuation models developed by independent valuation analytics providers. The models are market standard discounted cash flow models and all associated processes and controls are executed by Company personnel. These models take into consideration any unique characteristics of the derivatives in determining the appropriate valuation methodology to estimate expected cash flows. The fair values of these swaps are based on observable market inputs and are classified as Level 2 within the fair value hierarchy.

For forward bond purchase commitments with VIEs, the fair value of the derivative is based on the difference in the fixed purchase price and the current market value of the related bond prior to the settlement date. Since the bond is typically a public bond with readily available pricing, the derivatives associated with the forward purchase commitment are classified as Level 2 within the fair value hierarchy.

Commercial mortgage and other loans

Commercial mortgage and other loans include TREs, CMLs, MMLs and other loans. The Company's loan receivables do not have readily determinable market prices and generally lack market liquidity. Fair values for loan receivables are determined based on the present value of expected future cash flows discounted at the applicable U.S. Treasury or floating-rate benchmark yield plus an appropriate spread that considers other risk factors, such as credit and liquidity risk. The spreads are a significant component of the pricing inputs and are generally considered unobservable. Therefore, these investments are classified as Level 3 within the fair value hierarchy.

Other investments

Other investments includes short-term investments that are measured at fair value where amortized cost approximates fair value.

Other policyholders' funds

The largest component of the other policyholders' funds liability is the Company's annuity line of business in Aflac Japan. The Company's annuities have fixed benefits and premiums. For this product, the Company estimates the fair value to be equal to the cash surrender value. This is analogous to the value paid to policyholders on the valuation date if they were to surrender their policy. The Company periodically checks the cash value against discounted cash flow projections for reasonableness. The Company considers its inputs for this valuation to be unobservable and have accordingly classified this valuation as Level 3.

Notes payable
The fair values of the Company's publicly issued notes payable are determined by utilizing available sources of observable inputs from third-party pricing vendors and are classified as Level 2. The Company's private placement notes payable are valued using the same internal models that the Company uses for its Japanese yen-denominated and U.S. dollar-denominated private placement investment portfolio. The fair values for these private placements are deemed Level 2 valuations, as they are model-derived valuations that are generated internally with all significant valuation inputs being observed in active markets. The fair values of the Company's Japanese yen-denominated loans approximate their carrying values and are classified as Level 3.


143
Transfers between Hierarchy Levels and Level 3 Rollforward

Assets and liabilities are transferred into Level 3 when a significant input cannot be corroborated with market observable data. This occurs when market activity decreases significantly and underlying inputs cannot be observed, current prices are not available, and/or when there are significant variances in quoted prices, thereby affecting transparency. Assets and liabilities are transferred out of Level 3 when circumstances change such that a significant input can be corroborated with market observable data. This may be due to a significant increase in market activity, a specific event, or one or more significant input(s) becoming observable.

The following tables present the changes in fair value of the Company's investments carried at fair value classified as Level 3 as of December 31.

145
The following is a discussion of the significant unobservable inputs or valuation techniques used in determining the fair value of securities classified as Level 3.

Credit Spreads

The Company holds certain assets that are of a unique, specialized, and/or securitized nature that do not trade on a regular basis in an active market, which makes their fair values difficult to estimate. Most of these assets are managed by external asset managers and the Company utilizes these managers for their expertise when evaluating various inputs used to determine the fair values for these assets, including identifying the appropriate credit or risk spread over risk-free interest rates that incorporates the unique nature or structure of the asset in the valuations. For those assets of a similar nature but not managed by external asset managers, the Company internally estimates the spreads and risk adjustments over risk-free interest rates that reflect the unique nature or structure of the asset as well as the current pricing environment and market conditions for comparable or related investments. Credit or risk spreads are an important input needed to complete the discounted cash flow analyses used to estimate an investment’s fair value. Credit or risk spreads underlying these fair values are a significant, unobservable input whose derivation is based on the Company’s evaluation of a combination of the external manager’s expertise and knowledge, the current pricing environment, and market conditions for the specific asset.

Offered Quotes

In circumstances where the Company's valuation model price is overridden because it implies a value that is not consistent with current market conditions, the Company will solicit bids from a limited number of brokers. The Company also receives unadjusted prices from brokers for certain of its mortgage and asset-backed securities. These quotes are non-binding but are reflective of valuation best estimates at that particular point in time. Offered quotes are an unobservable input in the determination of fair value of mortgage- and asset-backed securities, certain banks/financial institutions, certain other corporate, and equity securities investments.

Private Financials

The Company invests in the debt and equity securities of private companies operating in the cancer, healthtech, insurtech, finance, internet of things, big data and analytics sectors. Due to their private and often small, startup nature, these companies rely on capital provided by institutional and private equity investors for their ongoing operations. They do not have public securities that trade on a regular basis in an active market, which makes their fair values difficult to estimate. The Company values these investments on a cost basis with appropriate adjustments made based on monitoring private financial information provided by these companies. Adjustments to valuations are generally made as new funding tranches are executed or if the financial information provided significantly changes indicating the need for impairment. This private financial information is unobservable and is a significant determinant in the fair value of these corporate venture investments.

For additional information on the Company's investments and financial instruments, see Notes 1, 3 and 4.

Commissions deferred as a percentage of total acquisition costs deferred were 67% in 2025, compared with 69% in 2024 and 67% in 2023.

There were no changes to the inputs, judgments or methods used to determine amortization amounts during 2025 and 2024. The Company updated the assumptions used to determine amortization using the same assumptions as those used for measuring the liability for future policy benefits during 2025 and 2024. The Company recognizes the effects of changes in assumptions prospectively over the remaining contract term as a revision of the future amortization pattern.

There were no changes to the inputs, judgments or methods used in measuring the liability for future policy benefits in 2025 and 2024.

Discount Rate Methodology

The Company’s discount rate methodology involves constructing a current discount rate curve separately for discounting cash flows used to calculate the Japan and U.S. LFPB, reflective of the characteristics of the insurance liabilities, such as currency and tenor. Discount rates are updated each reporting period and require estimation techniques (e.g., interpolation, extrapolation) for determination of points on the curve for which there is limited or no observable market data.

Discount rates are determined using upper-medium grade (low credit risk) fixed-income instrument yields that reflect the duration characteristics of the liability. Locked-in discount rates are determined separately for each issue-year cohort as a single discount rate, calculated as the weighted-average of monthly upper-medium grade (low credit risk) fixed-income instrument forward curves in the calendar year, where the weights are the annualized premiums issued for each month of the cohort. The single discount rate for each issue-year cohort is determined by solving for a rate that produces an equivalent NPR to the forward curve and will remain unchanged after the calendar year of issue.

In the Aflac Japan segment, all long-duration insurance policies are denominated in Japanese yen. A significant portion of policies are characterized by tenors exceeding the availability of liquid market data in Japan for single-A rated (as a proxy for upper-medium grade) corporate Japanese yen-denominated debt. The discount rate curve is designed to prioritize the observable inputs where available, while past the last liquid point, the data is derived based on estimation techniques consistent with the fair value guidance in ASC 820. The Aflac Japan segment's curve utilizes liquid market indices tracking publicly traded Japanese yen-denominated single-A corporate debt for the initial 10-year tenor. For the bonds within these market indices where only local ratings are available, the Company prioritizes the bonds with local ratings that are equivalent to a single-A rating based on international rating standards.


152
For the discount rates applicable to tenors for which the Japan single-A debt market is not liquid but there is sufficient observable market data and/or the observable market data is available for similar instruments (between 10 and 30 years), the Company estimates tenor-specific single-A credit spreads and applies them to risk-free government rates. Lastly, for the tenors where there is limited or no observable single-A or similar market data or risk-free government rates (beyond 30 years), the discount curve is derived by extrapolation of risk-free rates beyond their last liquid point following the Smith-Wilson method and grading of the estimated forward credit spread anchored by the ultimate forward rate. The ultimate forward rate is based on the economic value-based solvency regime, which is consistent with the International Association of Insurance Supervisors (IAIS) Insurance Capital Standards (ICS) (effective for Aflac Japan's 2025 fiscal year-end, which is March 31, 2026), and is adjusted for credit and inflation components.

For the Aflac U.S. segment where all long-duration insurance policies are denominated in U.S. dollars and substantially all have cash flow duration within 30 years, for which the U.S. upper-medium grade fixed-income market is liquid and observable, the Company uses data from a liquid fixed-income market index tracking single-A U.S. corporate debt. For the insignificant portion of the policies with cash flow tenors exceeding 30 years, the discount curve beyond that tenor is extrapolated following the Smith-Wilson method from year 30 to the same ultimate forward rate calculated for the Japan discount curve at year 60 and held constant thereafter. The use of the same ultimate rate for U.S. and Japan segments is based on the assumption of long-term global economic convergence.

There were no changes to the methods used to determine the discount rates during the years ended December 31, 2025 and 2024.

Cash Flow Assumptions

Cash flow assumptions include (1) mortality, (2) morbidity and (3) termination or lapses.

Mortality rate assumptions are based on industry tables and adjusted for the Company's actual or expected experience. These assumptions typically vary by age, gender, and other demographic characteristics such as smoking status.

Morbidity assumptions are based on the Company's internal data and consider emerging experience. These assumptions are reflective of the coverage and benefits provided and generally vary by age, gender, duration, and any other material policyholder characteristics. In cases where a calendar-year trend is significant, future cash flow projections may include a trend adjustment.

In Japan, separate lapse assumptions are set based on actual or expected experience. These lapse and total termination rate assumptions vary by line of business and with policyholder characteristics such as duration. In the U.S., the majority of the future cash flows are modeled using total termination rates (which include both lapse and mortality) and are adjusted for actual experience. Policy provisions, such as reaching premium paid-up status, are taken into account when setting assumptions.

The Company evaluates actual experience compared with expected experience for cash flow assumptions each quarter.

•In 2025 and 2024, the variance of actual experience from expected experience was primarily due to favorable variances in morbidity assumptions as compared to actual experience.

The Company performs a more detailed review of its assumptions annually during the third quarter.

•In 2025, the Company's annual assumption review process resulted in favorable changes largely due to favorable morbidity assumptions in Japan and favorable morbidity and termination assumptions in the U.S.

•In 2024, the Company's annual assumption review process resulted in favorable changes largely due to recent favorable Japan morbidity experience.

Favorable morbidity experience has been reflected in the annual assumptions primarily due to lower utilization of certain cancer benefits, including reduced hospitalizations and fewer first-occurrence claims influenced by COVID-19-related behavioral changes. While recognizing ongoing uncertainty, management has reviewed these trends and incorporated elements of the observed experience into its assumptions where considered appropriate.

The following tables present the amount of expected future gross premiums and expected future policy benefits and expenses (undiscounted and discounted at the current period discount rate) by reporting segment and disaggregated by product type as of December 31. These tables are presented gross of internal and external ceded reinsurance.
Future gross premiums represent the expected amount of future premiums to be received. For limited-payment policies, the premiums are collected over a shorter period than the policy term over which benefits are provided. As a result, once the policy reaches premium paid-up status, the future gross premiums can be significantly less than the future benefit payments. Further, benefits and expenses are generally greater in the later years of a policy. These are the primary factors that result in future gross premiums lower than future benefit and expense payments for certain lines of business of the Company.

8.     REINSURANCE

The Company periodically enters into fixed quota-share coinsurance agreements in the normal course of business, primarily to provide additional capacity for future growth, optimize capital, limit losses, and minimize exposure to significant risks. For each of its reinsurance agreements, the Company determines whether the agreement provides indemnification against loss or liability relating to insurance risk in accordance with applicable accounting standards. These reinsurance transactions are indemnity reinsurance agreements that do not relieve the Company from its obligations to policyholders. In the event that the reinsurer is unable to meet their obligations, the Company remains liable for the reinsured claims.

The following table reconciles direct earned premiums, direct benefits and claims, excluding reserve remeasurement gains and losses, and reserve remeasurement gains and losses to net amounts after the effect of reinsurance for the years ended December 31.

The Company reported a deferred reinsurance gain liability related to reinsurance transactions, which represents ceded reserves in excess of consideration paid or consideration received in excess of assumed reserves. The remaining consolidated deferred reinsurance gain liability of $125 million and $146 million as of December 31, 2025 and 2024, respectively, is included in future policy benefits in the consolidated balance sheets and is being amortized over the expected lives of the policies. The amortization is included in benefits and claims in the consolidated statements of earnings.

The Company also reported a reinsurance recoverable with a remaining balance, net of allowance for credit losses of $161 million and $163 million as of December 31, 2025 and 2024, respectively. As of both December 31, 2025 and 2024, the related allowance for credit losses was $4 million. The allowance for credit losses is estimated using a PD / LGD method and the key credit quality indicator is the credit rating of the Company’s significant reinsurance counterparties. The Company uses external credit ratings focused on these reinsurers' financial strength and credit worthiness. As of December 31, 2025, the Company's significant reinsurance counterparties were rated A+. The Company monitors these credit ratings periodically, but not less frequently than quarterly.

Aflac Re is a Bermuda domiciled insurer that reinsures certain policies issued by ALIJ. The inter-segment amounts associated with these internal reinsurance transactions are eliminated in consolidation.

In October 2024, ALIJ entered into a coinsurance transaction whereby it ceded 30% of the liabilities associated with certain cancer insurance policies and riders to Aflac Re. This transaction transferred approximately $1.8 billion of reserves associated with these policies. Approximately $1.7 billion of assets were transferred from ALIJ to Aflac Re as consideration for assuming the reinsurance risk. This internal reinsurance transaction with Aflac Re has no financial statement impact on a consolidated basis, except for the effect of foreign currency accounting.

The pretax loss due to the early redemption of these notes was $137 million.

For the Company's Japanese yen-denominated notes and loans, the principal amount as stated in dollar terms will fluctuate from period to period due to changes in the yen/dollar exchange rate. The Company has designated the majority of its Japanese yen-denominated notes payable as a non-derivative hedge of the foreign currency exposure of the Company's investment in Aflac Japan.

The aggregate contractual maturities of notes payable during each of the years after December 31, 2025, are as follows:

Senior Note Facility Agreements

In August 2025, the Parent Company entered into two separate facility agreements: a 10-year facility agreement (2035 Facility Agreement) with a Delaware trust (2035 Trust) and a 30-year facility agreement (2055 Facility Agreement) with a Delaware trust (2055 Trust). In connection with these transactions, the trusts issued and sold pre-capitalized trust securities in private placements and invested the proceeds in a portfolio of principal and/or interest strips of U.S. Treasury securities (the Strips). These trusts are an off-balance sheet funding arrangement.

The 2035 Facility Agreement provides the Parent Company the right to issue and sell to the 2035 Trust from time to time up to $1.0 billion of 5.251% senior notes due August 2035 in exchange for a corresponding amount of the Strips held by the 2035 Trust. In return, the Parent Company agreed to pay a semiannual facility fee to the 2035 Trust at a rate of 0.9875% per annum applied to the unexercised amount of senior notes that the Parent Company could issue and sell to the 2035 Trust.

The 2055 Facility Agreement provides the Parent Company the right to issue and sell to the 2055 Trust from time to time up to $1.0 billion of 5.991% senior notes due August 2055 in exchange for a corresponding amount of the Strips held by the 2055 Trust. In return, the Parent Company agreed to pay a semiannual facility fee to the 2055 Trust at a rate of 1.1218% per annum applied to the unexercised amount of senior notes that the Parent Company could issue and sell to the 2055 Trust.

The Parent Company can redeem the senior notes at any time, in whole or in part, by returning the Strips to the trusts or by delivering cash at a redemption price equal to the greater of the principal amount or a make-whole redemption price, in each case plus accrued and unpaid interest to, but excluding, the date of redemption. As of December 31, 2025, the Parent Company had no senior note issuances under these facility agreements.

The Japan income tax rate for the fiscal years 2025, 2024 and 2023 was 28.0%. The Japan income tax rate will increase to 28.9% beginning April 1, 2026. The Bermuda corporate income tax rate for the 2025 fiscal year was 15%.

Aflac Japan holds certain U.S. dollar-denominated assets in a Delaware Statutory Trust (DST). These assets are mostly comprised of various U.S. dollar-denominated commercial mortgage loans. The functional currency of the DST for U.S. tax purposes was historically the Japanese yen. In 2022, the Company requested a change in tax accounting method through the Internal Revenue Service's automatic consent procedures to change the functional currency of the DST for U.S. tax purposes to the U.S. dollar. As a result, foreign currency translation gains or losses on assets held in the DST are no longer recognized for U.S. tax purposes. The non-taxable foreign currency translation gain/loss resulting from the method change resulted in the Company recognizing an income tax expense of $23 million in 2025. The Company recognized an income tax benefit of $208 million in 2024 and $174 million in 2023.

Income tax expense in the accompanying consolidated statements of earnings varies from the amount computed by applying the expected U.S. tax rate of 21% to pretax earnings.

The application of U.S. GAAP requires the Company to evaluate the recoverability of deferred tax assets and establish a valuation allowance if necessary to reduce the deferred tax asset to an amount that is more likely than not expected to be realized. The Company has determined no valuation allowance against its anticipatory foreign tax credits is necessary. The anticipatory foreign tax credit represents the foreign tax credit the Company will generate from the reversal of Japan deferred tax liabilities in the future. Deferred foreign tax credits are foreign tax credits generated in the current tax year by the Japanese life company, but are unable to be utilized until 2026 due to Japan's current tax year not closing until March 31, 2026. Based upon a review of the Company's anticipated future taxable income, and including all other available evidence, both positive and negative, the Company's management has concluded that it is more likely than not that all other deferred tax assets will be realized.

Under U.S. income tax rules, only 35% of non-life operating losses can be offset against life insurance taxable income each year. For current U.S. income tax purposes, as of December 31, 2025, there were non-life operating loss carryforwards of $26 million available to offset against future taxable income, which expire after December 31, 2040, and there were life operating loss carryforwards available to offset against future taxable income of $106 million, which do not expire. The Company has no capital loss carryforwards available to offset capital gains. The Company has a foreign tax credit carryforward of $296 million as of December 31, 2025, which expires after December 31, 2034.

The Company files federal income tax returns in the U.S., Japan, and Bermuda as well as state or prefecture income tax returns in various jurisdictions in the two countries. The 2023 U.S. federal consolidated tax return is currently under examination. There are currently no other open Federal, State, or local U.S. income tax audits. U.S. federal income tax returns for years before 2022 are no longer subject to examination. Japan corporate income tax returns for years before the tax year ended March 2023 are no longer subject to examination. Management believes it has established adequate tax liabilities and final resolution of all open audits is not expected to have a material impact on the Company's consolidated financial statements.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows for the years ended December 31:
(In millions)2025 2024 
Balance, beginning of year$0 $1 
Reductions for tax positions of prior years0   (1)
Balance, end of year$0 $0 

Included in the balance of the liability for unrecognized tax benefits at December 31, 2025 and 2024, were no tax positions for which the ultimate deductibility is highly certain, but for which there is uncertainty about the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period would not affect the annual effective tax rate, but would accelerate the payment of cash to the taxing authority to an earlier period. As of December 31, 2025, the Company did not have an accrual for permanent uncertainties and therefore did not have an effect on the annual effective rate.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company recognized no interest and penalties in 2025, and an immaterial amount of interest and penalties in 2024 and 2023.

12.     SHARE-BASED COMPENSATION
The Company has outstanding share-based awards under the Aflac Incorporated Long-Term Incentive Plan (as Amended and Restated February 14, 2017), as further amended on August 9, 2022 (the Plan). Share-based awards are designed to reward employees for their long-term contributions to the Company and provide incentives for them to remain with the Company. The number and frequency of share-based awards are based on competitive practices, operating results of the Company, government regulations, and other factors.

The Plan allows for a maximum number of shares issuable over its term of 75 million shares including 38 million shares that may be awarded in respect of awards other than options or stock appreciation rights. If any awards granted under the Plan are forfeited or are terminated before being exercised or settled for any reason other than tax forfeiture, then the shares underlying the awards will again be available under the Plan. As of December 31, 2025, approximately 32.6 million shares were available for future grants under this plan.

The Plan allows awards to Company employees as follows:
•Stock options
◦Incentive stock options
◦Non-qualifying stock options
•Performance-based restricted stock awards and units (performance-based restricted stock)
•Restricted stock awards and units (restricted stock)
•Stock appreciation rights

Non-employee directors are eligible for grants of non-qualifying stock options, restricted stock, and stock appreciation rights.

Share-based awards granted to U.S.-based grantees are settled with authorized but unissued Company stock, while those issued to Japan-based grantees are settled with treasury shares.

Vesting Schedules

Stock options and stock appreciation rights have an expiration date of no later than 10 years from the grant date. Generally, the vesting period for share-based awards is the requisite service period, which is typically three years for employees and one year for non-employee directors. Vesting for employees is generally on a ratable basis over the three years, typically subject to continued employment.

For performance-based restricted stock, vesting is also contingent on certain performance conditions typically achieved over three years.

The Compensation Committee of the board of directors has the discretion to determine vesting schedules.

Share-Based Compensation Expense

Share-based compensation expense consists primarily of expenses for stock options, restricted stock, and performance-based restricted stock. The expense is included in insurance and other expenses in the consolidated statements of earnings.

The following table presents the impact of share-based compensation expense for the years ended December 31.

Stock options and stock appreciation rights granted under the Plan have an exercise price of at least the fair market value of the underlying stock on the grant date. For awards with an exercise price currently below the quoted closing price of the Company's common stock, the total pretax intrinsic value of stock options exercised during the period is based on the difference between the exercise price of the stock options and the closing price of the Company's common stock of $110.27 as of December 31, 2025.

The Company estimates the fair value of each stock option granted using the Black-Scholes-Merton multiple option approach. Expected volatility is based on historical periods generally commensurate with the estimated terms of the options. The Company uses historical data to estimate option exercise and termination patterns within the model. Separate groups of employees that have similar historical exercise patterns are stratified and considered separately for valuation purposes. The expected term of options granted is derived from the output of the Company's option model and represents the weighted-average period of time that options granted are expected to be outstanding. The Company bases the risk-free interest rate on the Treasury note rate with a term comparable to that of the estimated term of the options.

The following table presents the assumptions used in valuing options granted, if applicable, during the years ended December 31.

As of December 31, 2025, the aggregate intrinsic value of stock options outstanding and in-the-money stock options exercisable was $24 million.

Performance-Based Restricted Stock

Under the Plan, the Company grants selected executive officers performance-based restricted stock with vesting contingent upon meeting various financial performance goals or other Company identified metrics. Performance-based restricted stock is generally granted at-the-money and contingently cliff vest over a period of three years, generally subject to continued employment. Additionally, grants of performance-based restricted stock may also be contingent upon certain market conditions. Compensation expense for performance-based restricted stock subject to accelerated vesting at the date of retirement eligibility is expensed over the implicit service period.

In 2025, the Company granted 284 thousand performance-based restricted stock, which are contingent on the achievement of the Company's financial performance goals and certain market conditions. On the date of grant, the Company estimated the fair value of performance-based restricted stock with market conditions using a Monte Carlo simulation model. The model discounts the value of the stock at the assumed vesting date based on a risk-free interest rate. Based on estimates of actual performance versus the vesting thresholds, the calculated fair value percentage pay-out estimate will be updated each quarter. Actual performance, including modification for relative total shareholder return, may result in the ultimate award of 0% to 200% percent of the initial number of performance-based restricted stock issued, with the potential for no award if the Company's performance goals are not achieved.

In 2025, the Company also granted 10 thousand performance-based stock units, which are contingent on the achievement of certain Company determined metrics. Based on estimates of actual performance versus the vesting thresholds, the calculated fair value percentage pay-out estimate will be updated each quarter. Actual performance may result in the ultimate award of 0% to 100% percent of the initial number of performance-based restricted stock issued, with the potential for no award if the Company's determined metrics are not achieved.

The Company uses third-party analyses to assist in developing the assumptions used in, as well as calibrating, a Monte Carlo simulation model. The Company is responsible for determining the assumptions used in estimating the fair value of its share-based compensation awards.

Key assumptions used to value performance-based restricted stock granted during 2025 follows:
(In millions)2025
Expected volatility (based on Aflac Inc. and peer group historical daily stock price) 21.3 %
Expected life from grant date (years)2.9
Risk-free interest rate (based on U.S. Treasury yields at the date of grant)4.2 %

As of December 31, 2025, total compensation cost not yet recognized in the Company's financial statements related to restricted stock was $38 million, of which $13 million (1.6 million shares) was related to performance-based restricted stock. The Company expects to recognize these amounts over a weighted-average period of approximately 1.7 years. There are no other contractual terms covering restricted stock once vested.

13.     BENEFIT PLANS

Pension and Other Postretirement Plans

The Company has funded defined benefit plans in Japan and the U.S.; however, future benefits under the U.S. plan were frozen effective January 1, 2024, which resulted in the Company recognizing a curtailment gain of $49 million in 2023. As part of the U.S. plan freeze, the company offered lump sum payments to certain participants. The lump sum payments were distributed in the fourth quarter of 2024 and resulted in a settlement charge of $18 million in 2024 due to the payments being greater than the settlement threshold. In January 2025, the Company purchased a nonparticipating single premium group annuity contract from an external insurer to settle its obligations under the U.S. defined pension plan and paid to the insurer the related annuity premium. As a result, the Company recognized a settlement charge of $55 million in 2025. Effective April 1, 2025, the external insurer began making annuity payments to plan participants.

The Company also maintains non-qualified, unfunded supplemental retirement plans that provide defined pension benefits in excess of limits imposed by federal tax law for certain Japanese, U.S. and former employees. However, future benefits under the Company's Supplemental Executive Retirement Plan and Retirement Plan for Senior Officers were frozen effective January 1, 2024, provided that actively employed participants may continue to accrue service toward eligibility for early retirement benefits or delayed early retirement benefits.

The Company provides certain health care benefits for eligible U.S. retired employees, their beneficiaries and covered dependents (other postretirement benefits). The health care plan is contributory and unfunded. For certain employees and former employees, additional coverage is provided for all medical expenses for life. Effective January 1, 2014, the plan was frozen to new participants.

The Company determines its discount rate assumption for its U.S. pension retirement obligations based on indices for AA corporate bonds with an average duration of approximately 13 years, and determination of the U.S. pension plan discount rate utilizes the 85-year extrapolated yield curve. In Japan, the discount rate assumption is determined using the yield curve equivalent approach, and participant salary and future salary increases are factors in determining pension benefit cost or the related pension benefit obligation.

The Company bases its assumption for the long-term rate of return on assets on historical trends (10-year or longer historical rates of return for the Japanese plan assets), expected future market movement, as well as the portfolio mix of securities in the asset portfolio including, but not limited to, style, class and equity and fixed income allocations. In addition, the Company's consulting actuaries evaluate its assumptions for long-term rates of return under Actuarial Standards of Practice (ASOP). Under the ASOP, the actual portfolio type, mix and class are modeled to determine a best estimate of the long-term rate of return. The Company in turn uses those results to further validate its own assumptions.

The funding policy for the Company's non-qualified supplemental defined benefit pension plans and other postretirement benefits plan is to contribute the amount of the benefit payments made during the year.

The investment objective of the Company's Japanese funded defined benefit plans is to preserve the purchasing power of the plan's assets and earn a reasonable inflation-adjusted rate of return over the long term. Furthermore, the Company seeks to accomplish these objectives in a manner that allows for the adequate funding of plan benefits and expenses. In order to achieve these objectives, the Company's goal is to maintain a conservative, well-diversified and balanced portfolio of high-quality equity, fixed-income and money market securities. As a part of its strategy, the Company has established strict policies covering quality, type and concentration of investment securities. For the Company's Japanese plan, these policies include limitations on investments in derivatives including futures, options and swaps, and low-liquidity investments such as real estate, venture capital investments, and privately issued securities. The Company is also prohibited from trading on margin.

The plan fiduciaries for the Company's funded defined benefit plans have developed guidelines for asset allocations reflecting a percentage of total assets by asset class, which are reviewed on an annual basis. Asset allocation targets as of December 31, 2025 were as follows:

401(k) Plan

The Company sponsors a 401(k) plan in which it matches a portion of U.S. employees' contributions. The plan provides for salary reduction contributions by employees and, in 2025, 2024, and 2023, provided matching contributions by the Company of 100% of each employee's contributions which were not in excess of 4% of the employee's annual cash compensation. The Company also provides a nonelective contribution to the 401(k) plan of 4% of annual cash compensation. Effective January 1, 2024, the nonelective 401(k) employer contribution was extended to U.S. employees who were participants in the defined benefit plan prior to the freeze of future benefits on January 1, 2024.

The 401(k) contributions by the Company, included in acquisition and operating expenses in the consolidated statements of earnings, were $21 million in 2025 and $21 million in 2024 and $20 million in 2023. The plan trustee held approximately 1.7 million shares of the Company's common stock for plan participants at December 31, 2025.

Stock Bonus Plan

Aflac U.S. maintains a stock bonus plan for eligible U.S. sales associates. Plan participants receive shares of Aflac Incorporated common stock based on their new annualized premium sales and their first-year persistency of substantially all new insurance policies. The cost of this plan, which was capitalized as deferred policy acquisition costs, amounted to $22 million in 2025 and $21 million in 2024 and $19 million in 2023.

14.     STATUTORY ACCOUNTING AND DIVIDEND RESTRICTIONS
The Company's insurance subsidiaries are required to report their results of operations and financial position to insurance regulatory authorities on the basis of statutory accounting practices prescribed or permitted by such authorities.

Aflac Japan must report its results of operations and financial position to the Japanese Financial Services Agency (FSA) on a Japanese regulatory accounting basis as prescribed by the FSA. Japanese regulatory accounting practices differ in many respects from U.S. GAAP. For example, under Japanese regulatory accounting practices, policy acquisition costs are expensed immediately; policy benefit and claim reserving methods and assumptions are different; premiums are recognized on a cash basis; different consolidation criteria apply to VIEs; reinsurance is recognized on a different basis; and investments can have a separate accounting classification and treatment referred to as policy reserve matching bonds (PRM). Capital and surplus of Aflac Japan, based on current Japanese regulatory accounting practices, was $6.9 billion at December 31, 2025, compared with and $8.1 billion at December 31, 2024.

Aflac, CAIC and TOIC report statutory financial statements that are prepared on the basis of accounting practices prescribed or permitted by the Nebraska Department of Insurance (NDOI). The NDOI recognizes statutory accounting principles and practices prescribed or permitted by the state of Nebraska for determining and reporting the financial condition and results of operations of an insurance company, and for determining a company's solvency under Nebraska insurance law. 

Aflac New York reports statutory financial statements that are prepared on the basis of accounting practices prescribed or permitted by the New York State Department of Financial Services (NYSDFS). The NYSDFS recognizes statutory accounting principles and practices prescribed or permitted by the state of New York for determining and reporting the financial condition and results of operations of an insurance company, and for determining a company's solvency under New York insurance law.


184
Statutory Accounting Principles (SAP) as detailed by the National Association of Insurance Commissioners' (NAIC) Accounting Practices and Procedures Manual have been adopted by both the state of Nebraska and the state of New York as a component of those prescribed or permitted practices. Statutory accounting practices primarily differ from U.S. GAAP by charging policy acquisition costs to expense as incurred, establishing future policy benefit liabilities using different actuarial assumptions as well as valuing investments and certain assets and accounting for deferred taxes on a different basis. Additionally, the Director of the NDOI and the Superintendent of the NYSDFS each have the right to permit other specific practices which deviate from prescribed practices. Aflac, CAIC, TOIC and Aflac New York had no permitted practices as of December 31, 2025, and 2024.

Aflac Re is licensed by the BMA as a long-term insurer and is subject to the Bermuda Insurance Act of 1978 (Bermuda Insurance Act). Aflac Re is required to file annual and quarterly returns for its Bermuda Solvency Capital Requirement (BSCR) which utilizes an Economic Balance Sheet (EBS) framework to determine Aflac Re’s Enhanced Capital Requirement (ECR). Aflac Re is also subject to a Minimum Margin of Solvency (MSM) related to its statutory financial statements. The MSM is equal to the greater of $8,000,000; 2% of the first $500,000,000 of assets under management plus 1.5% of the amount by which assets exceed $500,000,000; or 25% of ECR.

Under the EBS framework, Aflac Re is required to value assets equal to U.S. GAAP fair values, and insurance reserves are valued using technical provisions which consist of a best estimate liability plus a risk margin. The best estimate liability can be calculated by applying the standard approach or, with regulatory approval, the scenario-based approach. The standard approach uses discount rates for insurance reserves as prescribed by the BMA. The scenario-based approach uses a discount rate based on the yield of eligible assets owned by the insurer as determined using a series of prescribed stress scenarios. At December 31, 2025 and 2024, Aflac Re was in compliance with the ECR and MSM requirements. Statutory capital and surplus of Aflac Re, based on Bermuda statutory accounting practices, was $991 million at December 31, 2025, compared with $581 million at December 31, 2024.

The Parent Company depends on its subsidiaries for cash flow, primarily in the form of dividends and management fees. Consolidated retained earnings in the accompanying financial statements largely represent the undistributed earnings of the Company's insurance subsidiaries. Amounts available for dividends, management fees and other payments to the Parent Company by its insurance subsidiaries may fluctuate due to different accounting methods required by regulatory authorities. These payments are also subject to various regulatory restrictions and approvals related to safeguarding the interests of insurance policyholders. The Company's U.S. life insurance entities must maintain adequate risk-based capital (RBC) for U.S. regulatory authorities, Aflac Japan must maintain adequate solvency margins for Japanese regulatory authorities, and Aflac Re must maintain minimum capital requirements for Bermuda regulatory authorities.


185
The maximum amount of dividends that can be paid to the Parent Company by Aflac, CAIC and TOIC without prior approval of Nebraska's director of insurance is the greater of the net income from operations, which excludes net investment gains, for the previous year determined under statutory accounting principles, or 10% of statutory capital and surplus as of the previous year-end. In 2025, Aflac declared dividends of $906 million, compared with $976 million in 2024. Dividends declared by Aflac during 2026 in excess of $664 million would require such approval. In 2025, CAIC declared and paid an extraordinary distribution of $240 million to the Parent Company. CAIC did not declare dividends in 2024, and TOIC did not declare dividends in 2025 or 2024. From time to time, Aflac New York pays dividends to Aflac, the parent company of Aflac New York. Aflac New York may not pay dividends to Aflac without the prior approval of the NYSDFS. Aflac New York declared dividends of $46 million in 2025 and $54 million in 2024, which were authorized by the NYSDFS.

Aflac Japan is required to meet certain financial criteria as governed by the Companies Act of Japan in order to provide dividends to the Parent Company. Under these criteria, dividend capacity at Aflac Japan is defined as total equity excluding common stock and capital reserves but reduced for net after-tax unrealized losses on available-for-sale securities based on the previous fiscal year-end. Profits remitted by Aflac Japan to the Parent Company were as follows for the years ended December 31:

Profit remittances$2,681 $2,865 $2,623 ¥396.7 ¥441.6 ¥374.7 

Under the Bermuda Insurance Act, Aflac Re is prohibited from paying dividends in an amount that exceeds 25% of the prior year's statutory capital and surplus without an affidavit stating that Aflac Re will continue to meet its solvency margin. Further, Aflac Re may not reduce its total statutory capital by 15% or more without prior regulatory approval. Additionally, Aflac Re is not permitted to pay any dividends that would cause Aflac Re to fail to meet its minimum capital requirements. Aflac Re did not declare dividends in 2025 or 2024.

15.     COMMITMENTS AND CONTINGENT LIABILITIES

The Company is a defendant in various lawsuits and receives various regulatory inquiries considered to be in the normal course of business. Members of the Company's senior legal and financial management teams review litigation and regulatory inquiries on a quarterly and annual basis and the Company updates the related estimates, accruals, and disclosures, if any, based on such reviews. For litigation and regulatory matters where it is probable that a loss has been incurred, and the amount of that loss can be reasonably estimated, the Company establishes accruals for loss contingencies. Where a loss may be reasonably possible but not probable, or is probable but not reasonably estimable, no accrual is recorded. The final results of any litigation or regulatory inquiries cannot be predicted with certainty. Although some of this litigation is pending in states where large punitive damages, bearing little relation to the actual damages sustained by plaintiffs, have been awarded in recent years, the Company believes the outcome of pending litigation will not have a material adverse effect on its financial position, results of operations, or cash flows.

Cyber Incident

As previously disclosed, the Company identified an incident involving unauthorized access to a limited number of its systems in the U.S. on June 12, 2025. The Company promptly initiated its cybersecurity incident response protocols and believes it contained the unauthorized access within hours. The Company's systems were not affected by ransomware, and the Company remained able to serve its policyholders and underwrite policies, review claims, and otherwise service customers as usual. In December 2025, the Company determined that personal information associated with approximately 22.65 million individuals was involved. The Company has received questions from regulators and has pending disputes related to the June 2025 incident. The Company believes that the potential amount of loss cannot be reasonably estimated at this time.

Outsourcing Agreements and Other Commitments

The Company has an outsourcing agreement with a technology and consulting corporation that provides for mainframe computer operations, distributed mid-range server computer operations, and related support for Aflac Japan. The agreement has a remaining term of three years with an aggregate remaining cost of ¥33.6 billion ($215 million using the December 31, 2025 foreign exchange rate).


186
The Company has three outsourcing agreements with a management consulting and technology services company. The first agreement provides for application maintenance and development services for Aflac Japan.

The Company has a comprehensive agreement with a cloud-based software company to license software for Aflac Japan. The agreement has a remaining term of four years with an aggregate remaining cost of ¥6.6 billion ($42 million using the December 31, 2025 foreign exchange rate).

See Note 3 for details on certain investment commitments.

Guaranty Fund Assessments

The U.S. insurance industry has a policyholder protection system that is monitored and regulated by state insurance departments. These life and health insurance guaranty associations are state entities (in all 50 states as well as Puerto Rico and the District of Columbia) created to protect policyholders of an insolvent insurance company. All insurance companies (with limited exceptions) licensed to sell life or health insurance in a state must be members of that state’s guaranty association. Under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies that write the same line or similar lines of business.

Guaranty fund assessments for the years ended December 31, 2025, 2024 and 2023 were immaterial.

These notes are redeemable at the Parent Company’s option at any time, in whole but not in part, upon the occurrence of certain changes affecting U.S. taxation, as specified in the indenture governing the terms of the issuance. In addition, the notes maturing in October 2030, December 2032, June 2035 and June 2040 are redeemable at the Parent Company's option, in whole or in part from time to time, on or after July 18, 2030, September 14, 2032, December 5, 2034, and December 5, 2039, respectively, at a redemption price equal to the aggregate principal amount of the applicable series to be redeemed plus accrued and unpaid interest on the principal amount to be redeemed to, but excluding, the date of redemption.

In May 2025, the Parent Company issued four series of senior notes totaling ¥75.1 billion through a private placement.

For further information regarding these derivatives, see Notes 1 and 4 of the Notes to the Consolidated Financial Statements.
(C) Income Taxes
The Parent Company and its eligible U.S. subsidiaries file a consolidated U.S. federal income tax return.

ITEM 16. FORM 10-K SUMMARY
Not applicable.

Glossary of Selected Terms

Throughout this Annual Report on Form 10-K, the Company may use certain performance metrics and other terms which are defined below.

Adjusted net investment income is net investment income adjusted for i) amortized hedge cost/income related to foreign currency exposure management strategies and certain derivative activity and ii) net interest income/expense from foreign currency and interest rate derivatives associated with certain investment strategies, which are reclassified from net investment gains (losses) to net investment income. The Company considers adjusted net investment income important because it provides a more comprehensive understanding of the costs and income associated with the Company's investments and related hedging strategies. The metric is used in segment reporting as a component of segment profitability.

Affiliated corporate agency is an agency in Japan directly affiliated with a specific corporation that sells insurance policies primarily to its employees.

Annualized premiums in force is the amount of gross premium that a policyholder must pay over a full year in order to keep coverage. The growth of net earned premiums is directly affected by the change in premiums in force and by the change in weighted-average yen/dollar exchange rates. Management uses this measure as a key indicator of source of earnings.

Average weekly producer is the total number of writing agents, including brokers, in the U.S. who have produced greater than $0.00 during the production week - excluding any manual adjustments - divided by the number of weeks in the time period. The Company believes this metric allows sales management to monitor progress and needs, as well as serve as a leading indicator of future production capacity.

Capital buffer is an established dollar amount of liquidity at the Parent Company reserved for injecting capital into the insurance entities or general liquidity support for general expenses at the Parent Company.

Cancer policies in force are the number of policies attributable to cancer products currently in force at the end of the period for Aflac Japan. The number of policies increases with new sales and decreases with terminations. Management uses this number to measure the growth in Aflac Japan's cancer product line by policy count.

Earnings per basic share is net earnings divided by weighted-average number of shares outstanding for the period.

Earnings Per diluted share is net earnings divided by the weighted-average number of shares outstanding for
the period plus the weighted-average shares for the dilutive effect of share-based awards outstanding.

Economic Solvency Ratio (ESR) is an economic value-based soundness indicator that demonstrates whether the insurance company has sufficient capital to cover future risks. Assets and liabilities are evaluated at economic value, the risk amount incurred in a stressed environment is measured, and the capital sufficiency for this risk is assessed. The ESR level, which is the basis for supervisory intervention by the authorities, is set at 100%.

Group insurance is insurance issued to a group, such as an employer or trade association, that covers employees or association members and their dependents through certificates of coverage.

Individual insurance is insurance issued to an individual with the policy designed to cover that person and his or her dependents.

Policies in force are the number of policies currently in force at the end of the period for Aflac Japan. The number of policies increases with new sales and decreases with terminations. Management uses this number to measure the growth in the Company's business by policy count.

Liquidity support is an internally defined and established dollar amount of liquidity reserved for supporting potential collateral and settlements of derivatives at the Parent Company and short-term funding needs.
Net investment income is the income derived from interest and dividends on invested assets, after deducting investment expenses.

Net earned premiums is a financial measure that appears on the Company's consolidated statements of earnings and in its segment reporting. This measure reflects collected or due premiums that have been earned ratably on policies in force during the reporting period, reduced by premiums that have been ceded to third parties and increased by premiums assumed through reinsurance.

New annualized premium sales are sometimes referred to as new sales or sales. An operating measure that is not reflected on the Company's financial statements. New annualized premium sales generally represent annual premiums on policies and riders the Company sold and incremental increases from policy conversions that would be collected over a 12-month period assuming the policies remain in force for that entire period. For Aflac Japan, new annualized premium sales are determined by applications submitted during the reporting period. For Aflac U.S., new annualized premium sales are determined by applications that are


208

issued during the reporting period. Policy conversions are defined as the positive difference in the annualized premium when a policy upgrades in the current reporting period. The Company believes that this metric is a key indicator of the Company's future source of earnings.

New money yield is gross yields earned on purchases of fixed maturities, loan receivables, and equities. Purchases exclude capitalized interest, securities lending/repurchase agreements, short-term/cash activity, and alternatives. New money yield for equities is based on the assumed dividend yield at the time of purchase. The new money yield for Aflac Japan excludes the impact of any derivatives and associated amortized hedge costs associated with USD-denominated investments. Management uses this metric as a leading indicator of future investment earning potential.

Operating ratios are used to evaluate the Company's financial condition and profitability. Examples include: (1) Ratios to total adjusted revenues, which present expenses as percentage of total revenues and (2) Ratios to total premium, including benefit ratio. Operating ratios include: Benefit Ratio and Expense Ratio.

Portfolio book yield expressed as a percentage of the investments' book value, represents the gross return expected to be realized on a security at a point in time and is calculated for fixed maturity securities, commercial mortgage and other loans and equity securities. It excludes amortized hedge costs, investments in limited partnerships and short-term securities. The yield assumes any early redemption options will be exercised. Management uses this metric to measure the future total return on the portfolio.

Premium persistency is the percentage of premiums remaining in force at the end of a period, usually one year, and presented on a trailing 12-month average basis. For example, 95% persistency would mean that 95% of the premiums in force at the beginning of a period are still in force at the end of the period. The Company believes that this metric is a key driver of in force levels, which is a key measure of the size of the Company's business and future sources of earnings.

Pretax adjusted earnings are earnings as adjusted before the application of income taxes. This measure is used in the Company's segment reporting.

Pretax adjusted profit margin is adjusted earnings divided by adjusted revenues, before taxes are applied. This measure is used in the Company's segment reporting.

Return on average invested assets is net investment income as a percentage of average invested assets during the period. Management uses this metric to demonstrate how the Company's actual net investment income results represent an overall return on the
portfolio to provide a more comparative metric as the size of the Company's investment portfolio changes over time.

Risk-based Capital (RBC) Ratio is statutory adjusted capital divided by statutory required capital. This insurance ratio is based on rules prescribed by the National Association of Insurance Commissioners (NAIC) and provides an indication of the amount of statutory capital the insurance company maintains, relative to the inherent risks in the insurer’s operations.

Solvency Margin Ratio (SMR) is solvency margin total divided by one half of the risk total. This insurance ratio is prescribed by the Japan Financial Services Agency (FSA) and is used for all life insurance companies in Japan to measure the adequacy of the company’s ability to pay policyholder claims in the event actual risks exceed expected levels.

Statutory earnings are earnings determined according to accounting rules prescribed by the National Association of Insurance Commissioners (NAIC), as modified by the insurance department in the insurance company’s state of domicile. These statutory accounting rules are different from U.S. GAAP and are intended to emphasize policyholder protection and company solvency.

Weighted-average foreign exchange rate is Japan segment operating earnings for the period (excluding hedge costs) in yen divided by Japan segment operating earnings for the period (excluding hedge costs) in U.S. dollars. Management uses this metric to evaluate and determine consolidated results on foreign currency effective basis.
