Notes to the Condensed Consolidated Financial Statements

Note 1 – Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements of T-Mobile US, Inc. (“T-Mobile,” “we,” “our,” “us” or the “Company”) include all adjustments of a normal recurring nature necessary for the fair presentation of the results for the interim periods presented. The results for the interim periods are not necessarily indicative of those for the full year. The condensed consolidated financial statements should be read in conjunction with our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2017.

The condensed consolidated financial statements include the balances and results of operations of T-Mobile and our consolidated subsidiaries. We consolidate majority-owned subsidiaries over which we exercise control, as well as variable interest entities (“VIE”) where we are deemed to be the primary beneficiary and VIEs which cannot be deconsolidated, such as those related to Tower obligations (Tower obligations are included in VIEs related to the 2012 Tower Transaction. See Note 8 - Tower Obligations included in our Annual Report on Form 10-K for the year ended December 31, 2017). Intercompany transactions and balances have been eliminated in consolidation.

The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires our management to make estimates and assumptions which affect the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which our management believes are reasonable under the circumstances. These estimates are inherently subject to judgment and actual results could differ from those estimates.

Accounting Pronouncements Adopted During the Current Year

Revenue

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” and has since modified the standard with several ASUs (collectively, the “new revenue standard”). The new revenue standard requires entities to recognize revenue through the application of a five-step model, which includes: identification of the contract; identification of the performance obligations; determination of the transaction price; allocation of the transaction price to the performance obligations; and recognition of revenue as the entity satisfies the performance obligations. We adopted the new revenue standard on January 1, 2018, using the modified retrospective method with the cumulative effect of initially applying the guidance recognized at the date of initial application. Comparative information has not been restated and continues to be reported under the standards in effect for those periods. We have applied the new revenue standard only to contracts not completed as of the date of initial application, referred to as open contracts. We have elected the practical expedient that permits an entity to reflect the aggregate effect of all of the modifications (on a contract-by-contract basis) that occurred before the date of initial application in determining the transaction price, identifying the satisfied and unsatisfied performance obligations, and allocating the transaction price to the performance obligations. Electing this practical expedient does not have a significant impact on our financial statements due to the short-term duration of most of our contracts and the nature of our contract modifications.

We have implemented significant new revenue accounting systems, processes and internal controls over revenue recognition to assist us in the application of the new revenue standard.

Revenue Recognition

We primarily generate our revenue from providing wireless services to customers and selling or leasing devices and accessories. Our contracts with customers may involve multiple performance obligations, which include wireless services, wireless devices or a combination thereof, and we allocate the transaction price between each performance obligation based on its relative standalone selling price.

Index for Notes to the Condensed Consolidated Financial Statements

Significant Judgments

The most significant judgments affecting the amount and timing of revenue from contracts with our customers include the following items:


•	For transactions where we recognize a significant financing component, judgment is required to determine the discount rate. For equipment installment plan (“EIP”) sales, the discount rate used to adjust the transaction price primarily reflects current market interest rates and the estimated credit risk of the customer.


•	Our products are generally sold with a right of return, which is accounted for as variable consideration when estimating the amount of revenue to recognize. Expected device returns are estimated based on historical experience.

•

Sales of equipment to indirect dealers who have been identified as our customer (referred to as the sell-in model) often include credits subsequently paid to the dealer as a reimbursement for any discount promotions offered to the end consumer. These credits (payments to a customer) are accounted for as variable consideration when estimating the amount of revenue to recognize from the sales of equipment to indirect dealers and are estimated based on historical experience and other factors, such as expected promotional activity.

•

Promotional bill credits offered to a customer on an equipment sale that are paid over time and are contingent on the customer maintaining a service contract may result in an extended service contract based on whether a substantive penalty is deemed to exist. Determining whether contingent bill credits result in a substantive termination penalty, and determining the term over which a substantive termination penalty exists, may require significant judgment.


•	For capitalized contract costs, determining the amortization period as well as assessing the indicators of impairment may require significant judgment.


•	The determination of the standalone selling price for contracts that involve more than one product or service (or performance obligation) may require significant judgment.


•	The identification of distinct performance obligations within our service plans may require significant judgment.

Wireless Services Revenue

We generate our wireless services revenues from providing access to, and usage of, our wireless communications network. Service revenues also include revenues earned for providing value added services to customers, such as handset insurance services. Service contracts are billed monthly either in advance or arrears, or are prepaid. Generally, service revenue is recognized as we satisfy our performance obligation to transfer service to our customers. We typically satisfy our stand-ready performance obligations, including unlimited wireless services, evenly over the contract term. For usage-based and prepaid wireless services, we satisfy our performance obligations when services are rendered.

Revenue for service contracts that we assess are not probable of collection is not recognized until the contract is completed and cash is received. Collectibility is re-assessed when there is a significant change in facts or circumstances. Our assessment of collectibility considers whether we may limit our exposure to credit risk through our right to stop transferring additional service in the event the customer is delinquent.

Consideration payable to a customer is treated as a reduction of the total transaction price, unless the payment is in exchange for a distinct good or service, such as certain commissions paid to dealers.

Revenue is recorded net of costs paid to another party for performance obligations where we arrange for the other party to transfer goods or services to the customer (i.e., when we are acting as an agent). For example, performance obligations relating to services provided by third-party content providers where T-Mobile neither controls a right to the content provider’s service nor controls the underlying service itself are presented net because T-Mobile is acting as an agent.

Federal Universal Service Fund and other regulatory fees are assessed by various governmental authorities in connection with the services we provide to our customers and are included in Cost of services. When we separately bill and collect these regulatory fees from customers, they are recorded in Total service revenues in our Condensed Consolidated Statements of Comprehensive Income.

We have made an accounting policy election to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by T-Mobile from a customer (for example, sales, use, value added, and some excise taxes).

Index for Notes to the Condensed Consolidated Financial Statements

Equipment Revenues

We generate equipment revenues from the sale or lease of mobile communication devices and accessories. For performance obligations related to equipment contracts, we typically transfer control at a point in time when the device or accessory is delivered to, and accepted by, the customer or dealer. We have elected to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of assessing such activities as performance obligations. We estimate variable consideration (e.g. device returns or certain payments to indirect dealers) based on historical experience as well as other factors, such as expected trends. Equipment sales not probable of collection are generally recorded as payments are received. Our assessment of collectibility considers contract terms such as down payments that reduce our exposure to credit risk.

We offer certain customers the option to pay for devices and accessories in installments using an EIP. Generally, we recognize as a reduction of the total transaction price the effects of a financing component in contracts where customers purchase their devices and accessories on an EIP with a term of more than one year, including those financing components that are not considered to be significant to the contract. However, we have elected the practical expedient to not recognize the effects of a significant financing component for contracts where we expect, at contract inception, that the period between the transfer of a performance obligation to a customer and the customer’s payment for that performance obligation will be one year or less.

In addition, for customers who enroll in our Just Upgrade My Phone (“JUMP!”^®) program, we recognize a liability based on the estimated fair value of the specified-price trade-in right guarantee. The fair value of the guarantee is deducted from the transaction price under the new revenue standard, and the remaining transaction price is allocated to other elements of the contract, including service and equipment performance obligations. See “Guarantee Liabilities” in Note 1 - Summary of Significant Accounting Policies included in our Annual Report on Form 10-K for the year ended December 31, 2017.

In 2015, we introduced JUMP! On Demand, which allows customers to lease a device and upgrade their leased wireless device for a new device up to one time per month. To date, all of our leased wireless devices are accounted for as operating leases and estimated contract consideration is allocated between lease elements and non-lease elements (such as service and equipment performance obligations) based on the relative standalone selling price of each performance obligation in the contract. Lease revenues are recorded as equipment revenues and recognized as earned on a straight-line basis over the lease term. Lease revenues on contracts not probable of collection are limited to the amount of payments received. See “Property and Equipment” in Note 1 - Summary of Significant Accounting Policies included in our Annual Report on Form 10-K for the year ended December 31, 2017.

Contract Balances

Generally, T-Mobile devices and service plans are available at standard prices, which are maintained on price lists and published on our website and/or within our retail stores.

For contracts that involve more than one product or service that are identified as separate performance obligations, the transaction price is allocated to the performance obligations based on their relative standalone selling prices. Standalone selling price is the price at which T-Mobile would sell the good or service separately to a customer and is most commonly evidenced by the price at which T-Mobile sells that good or service separately in similar circumstances and to similar customers.

A contract asset is recorded when revenue is recognized in advance of our right to receive consideration (i.e., we must perform additional services in order to receive consideration). Amounts are recorded as receivables when our right to consideration is unconditional. When consideration is received, or we have an unconditional right to consideration in advance of delivery of goods or services, a contract liability is recorded. The transaction price can include non-refundable upfront fees, which are allocated to the identifiable performance obligations.

Contract assets are included in Other current assets and Other assets and contract liabilities are included in Deferred revenue in our Condensed Consolidated Balance Sheets.

Index for Notes to the Condensed Consolidated Financial Statements

Contract Modifications

Our service contracts allow customers to frequently modify their contracts without incurring penalties in many cases. Each time a contract is modified, we evaluate the change in scope or price of the contract to determine if the modification should be treated as a separate contract, as if there is a termination of the existing contract and creation of a new contract, or if the modification should be considered a change associated with the existing contract. We typically do not have significant impacts from contract modifications.

Contract Costs

We incur certain incremental costs to obtain a contract that we expect to recover, such as sales commissions. We record an asset when these incremental costs to obtain a contract are incurred and amortize them on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates.

We amortize deferred costs incurred to obtain service contracts on a straight-line basis over the term of the initial contract and anticipated renewal contracts to which the costs relate. However, we have elected the practical expedient permitting expensing of costs to obtain a contract when the expected amortization period is one year or less.

Incremental costs to obtain equipment contracts (e.g., commissions paid on device and accessory sales) are recognized when the equipment is transferred to the customer.

Financial Statement Impacts of Applying the New Revenue Standard

The cumulative effect of initially applying the new revenue standard to all open contracts as of January 1, 2018 is as follows:



	January 1, 2018
(in millions)	Beginning Balance			Cumulative Effect Adjustment		Beginning Balance, As Adjusted
Assets
Other current assets	$	1,903		$	140	$	2,043
Other assets	912			150		1,062
Liabilities and Stockholders’ Equity
Deferred revenue	$	779		$	4	$	783
Deferred tax liabilities	3,537			73		3,610
Accumulated deficit	(16,074		)	213		(15,861		)

The most significant impacts upon adoption of the new revenue standard on January 1, 2018 include the following items:


•	A deferred contract cost asset of $150 million was recorded at transition in Other assets in our Condensed Consolidated Balance Sheets for incremental contract acquisition costs paid on open contracts, which consists primarily of commissions paid to acquire branded postpaid service contracts; and


•	A contract asset of $140 million was recorded at transition in Other current assets in our Condensed Consolidated Balance Sheets primarily for contracts with promotional bill credits offered to customers on equipment sales that are paid over time and are contingent on the customer maintaining a service contract.

The most significant impacts to financial statement results as reported under the new revenue standard as compared to the previous revenue standard for the current reporting period are as follows:


•	Under the new revenue standard, certain commissions paid to dealers previously recognized as a reduction to Equipment revenues in our Condensed Consolidated Statements of Comprehensive Income are now recorded as commission costs in Selling, general and administrative expense.

•

Contract costs capitalized for new contracts will accumulate in Other assets in our Condensed Consolidated Balance Sheets during 2018. As a result, there will be a net benefit to Operating income in our Condensed Consolidated Statements of Comprehensive Income during 2018 as capitalization of costs exceed amortization. As capitalized costs amortize into expense over time, the accretive benefit to Operating income anticipated in 2018 is expected to moderate in 2019 and normalize in 2020.

Index for Notes to the Condensed Consolidated Financial Statements

•

For contracts with promotional bill credits that are contingent on the customer maintaining a service contract that result in an extended service contract, a contract asset is recorded when control of the equipment transfers to the customer and is subsequently amortized as a reduction to Total service revenues in our Condensed Consolidated Statements of Comprehensive Income over the extended contract term.

See disclosures related to Contracts with Customers under the new revenue standard in Note 11 - Revenue from Contracts with Customers.

Statement of Cash Flows

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (the “new cash flow standard”). The new cash flow standard is intended to reduce current diversity in practice and provides guidance on how certain cash receipts and payments are presented and classified in the statement of cash flows. We adopted the new cash flow standard on January 1, 2018, which was the date it became effective for us. We have applied the new cash flow standard retrospectively to all periods presented. The new cash flow standard impacted the presentation of cash flows related to our beneficial interests in securitization transactions, which is the deferred purchase price, resulting in a reclassification of cash inflows from Operating activities to Investing activities of $1.3 billion and $1.1 billion for the three months ended September 30, 2018 and 2017, respectively, and $4.0 billion and $3.1 billion for the nine months ended September 30, 2018 and 2017, respectively, in our Condensed Consolidated Statements of Cash Flows. The new cash flow standard also impacted the presentation of our cash payments for debt prepayment and debt extinguishment costs, resulting in a reclassification of cash outflows from Operating activities to Financing activities of $212 million and $188 million for the nine months ended September 30, 2018 and 2017, respectively, in our Condensed Consolidated Statements of Cash Flows. There were no cash payments for debt prepayment and debt extinguishment costs during the three months ended September 30, 2018 and 2017.

Financial Instruments

In January 2016, the FASB issued ASU 2016-01, “Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities,” and has since modified the standard in February 2018 with ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments - Overall” (Subtopic 825-10). The standard addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The standard became effective for us, and we adopted the standard, on January 1, 2018. The standard requires the impact of adoption to be recorded to retained earnings under a modified retrospective approach. The implementation of this standard did not have a material impact on our condensed consolidated financial statements.

Income Taxes

In October 2016, the FASB issued ASU 2016-16, “Accounting for Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory.” The standard requires that the income tax impact of intra-entity sales and transfers of property, except for inventory, be recognized when the transfer occurs. The standard became effective for us, and we adopted the standard, on January 1, 2018. The standard requires any deferred taxes not yet recognized on intra-entity transfers to be recorded to retained earnings under a modified retrospective approach. The implementation of this standard did not have a material impact on our condensed consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

Leases

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” and has since modified the standard with several ASUs (collectively, the “new lease standard”). The new lease standard requires most lessees to report a right-of-use asset and a lease liability. The income statement recognition is similar to existing lease accounting and is based on lease classification. The new lease standard requires lessees and lessors to classify most leases using principles similar to existing lease accounting. For lessors, the new lease standard modifies the classification criteria and the accounting for sales-type and direct financing leases. The new lease standard provides entities two options for applying the modified retrospective approach (1) retrospectively to each prior reporting period presented in the financial statements with the cumulative-effect adjustment recognized at the beginning of the earliest comparative period presented or (2) retrospectively at the beginning of the period of adoption (January 1, 2019) through a cumulative-effect adjustment. TMUS plans to adopt the standard by recognizing and measuring leases at the adoption date with a cumulative effect of initially applying the guidance recognized at the date of initial application.

Index for Notes to the Condensed Consolidated Financial Statements

Our evaluation of the new lease standard is ongoing and includes assessing which of our arrangements qualify as a lease through detailed contract reviews and targeted inquiries and aggregating and validating lease data and related information as well as determining whether previous conclusions for certain transactions, such as failed sale leaseback arrangements under the previous lease standard, Leases (Topic 840), would change under the new lease standard. We are in the process of implementing significant new lease accounting systems, and cross-functional teams are working to update processes and identify new internal controls over lease recognition, which will ultimately assist in the application of the new lease standard. Additionally, we are assessing the practical expedients and policy elections provided by the new leasing standard.

We plan to adopt the new lease standard when it becomes effective for us beginning January 1, 2019 and the adoption of the new lease standard will result in the recognition of right-of-use assets and lease liabilities that have not previously been recorded, which we expect will have a material impact on our condensed consolidated financial statements.

Financial Instruments

In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The standard requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount. The standard will become effective for us beginning January 1, 2020 and will require a cumulative-effect adjustment to Accumulated deficit as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). Early adoption is permitted for us as of January 1, 2019. We are currently evaluating the impact this guidance will have on our condensed consolidated financial statements and the timing of adoption.

Derivatives and Hedging

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvement to Accounting for Hedging Activities.” The standard modified the guidance for the designation and measurement of qualifying hedging relationships and the presentation of hedge results. We adopted this standard on October 1, 2018 and will apply the standard to hedging transactions prospectively.

Cloud Computing Arrangements

In August 2018, the FASB issued ASU 2018-15, “Intangibles - Goodwill and Other - Internal-Use Software (Topic 350): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract.” The standard aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The standard will become effective for us beginning January 1, 2020 and can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Early adoption is permitted for us at any time. We are currently evaluating the impact this guidance will have on our condensed consolidated financial statements and the timing of adoption.

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (“SEC”) did not have, or are not believed by management to have, a significant impact on our present or future consolidated financial statements.

Note 2 - Significant Transactions

Business Combinations

During the nine months ended September 30, 2018, we completed the following acquisitions which were accounted for as business combinations:


•	On January 1, 2018, we closed on our previously announced Unit Purchase Agreement to acquire the remaining equity in Iowa Wireless Services, LLC (“IWS”), a 54% owned unconsolidated subsidiary, for a purchase price of $25 million.


•	On January 22, 2018, we completed our acquisition of television innovator Layer3 TV, Inc. (“Layer3 TV”) for cash consideration of $318 million.

Proposed Sprint Transaction

On April 29, 2018, we entered into a Business Combination Agreement (the “Business Combination Agreement”) to merge with Sprint Corporation (“Sprint”).

See Note 3 - Business Combinations for further information.

Hurricane Impacts

During the first quarter of 2018, we recognized $36 million in incremental costs to maintain services in Puerto Rico related to hurricanes that occurred in 2017. Additional costs incurred during the second and the third quarters related to hurricanes that occurred in 2017 were immaterial and are expected to be immaterial in the fourth quarter of 2018. During the first quarter of 2018, we received reimbursement payments from our insurance carriers of $94 million, previously accrued for as a receivable as of December 31, 2017. During the second quarter of 2018, we received reimbursement payments of $70 million. During the third quarter of 2018, we received reimbursement payments of $81 million and accrued an additional receivable of $63 million for reimbursement payments agreed to with our insurance carriers as of September 30, 2018 and received in October 2018.

During the third quarter of 2018, our operations in North Carolina and South Carolina experienced losses related to a hurricane, and we recognized $6 million in costs associated with these losses. Additional costs related to the hurricane are expected to be immaterial in the fourth quarter of 2018.

In October 2018, our operations in Florida experienced immaterial losses related to a hurricane. Additional costs related to the hurricane are expected to be incurred during the remainder of the fourth quarter of 2018.

The following table shows the hurricane impacts in our Condensed Consolidated Statements of Comprehensive Income for the three and nine months ended September 30, 2018:

Sales of Certain Receivables

In February 2018, the service receivable sale arrangement was amended to extend the scheduled expiration date to March 2019. In October 2018, we amended and restated the EIP sale arrangement to, among other things, extend the scheduled expiration date to November 2020 and expand the types of EIP receivables that may be sold. See Note 5 – Sales of Certain Receivables for further information.

Debt

During the nine months ended September 30, 2018, we completed significant transactions with both third parties and affiliates related to the issuance, borrowing and redemption of debt. See Note 9 - Debt for further information.

Repurchases of Common Stock

During the first half of 2018, we made additional repurchases of our common stock. Additionally, during the first quarter of 2018, Deutsche Telekom AG (“DT”), our majority stockholder and an affiliated purchaser, made additional purchases of our common stock. See Note 12 – Repurchases of Common Stock for further information.

Note 3 - Business Combinations

Proposed Sprint Transactions

On April 29, 2018, we entered into a Business Combination Agreement to merge with Sprint in an all-stock transaction at a fixed exchange ratio of 0.10256 shares of T-Mobile common stock for each share of Sprint common stock, or 9.75 shares of Sprint common stock for each share of T-Mobile common stock (the “Merger”). The combined company will be named “T-Mobile” and, as a result of the Merger, is expected to be able to rapidly launch a nationwide 5G network, accelerate innovation

Index for Notes to the Condensed Consolidated Financial Statements

and increase competition in the U.S. wireless, video and broadband industries. Neither T-Mobile nor Sprint on its own could generate comparable benefits to consumers.

The Merger and the other transactions contemplated by the Business Combination Agreement (collectively, the “Transactions”)

have been approved by the boards of directors of T-Mobile and Sprint. Immediately following the Merger, it is anticipated that DT and SoftBank Group Corp. will hold, directly or indirectly, on a fully diluted basis, approximately 41.7% and 27.3%, respectively, of the outstanding T-Mobile common stock, with the remaining approximately 31.0% of the outstanding T-Mobile common stock held by other stockholders, based on closing share prices and certain other assumptions as of October 1, 2018.

In connection with the entry into the Business Combination Agreement, T-Mobile USA, Inc. (“T-Mobile USA”) entered into a commitment letter, dated as of April 29, 2018 (as amended and restated on May 15, 2018, the “Commitment Letter”), with certain financial institutions named therein that have committed to provide up to $38.0 billion in secured and unsecured debt financing. As permitted by the terms of the Commitment Letter, on June 6, 2018, T-Mobile USA reduced the initial aggregate commitment under the Commitment Letter by $8.0 billion such that the remaining size of the commitment is currently $30.0 billion. The funding of the debt facilities provided for in the Commitment Letter is subject to the satisfaction of the conditions set forth therein, including consummation of the Merger. The proceeds of the debt financing provided for in the Commitment Letter will be used to refinance certain existing debt of us, Sprint and our and Sprint’s respective subsidiaries and for post-closing working capital needs of the combined company. In connection with the financing provided for in the Commitment Letter, we expect to incur certain fees if the Merger closes, including fees for the financial institutions structuring and providing the commitments for the secured term loan facility, secured revolving loan facility and the secured bridge loan, and certain take-out fees associated with the issuance of permanent secured bond debt in lieu of the secured bridge loan. We expect to incur up to approximately $275 million in fees if the Merger were to close on or after January 29, 2019. The fees increase to up to approximately $340 million if the closing date occurs on or after April 29, 2019. We have not accrued these fees as of September 30, 2018. We also may be required to draw down on the $7.0 billion secured term loan facility on May 1, 2019, and would be required to place the proceeds in escrow and pay interest thereon until the Merger closes.

In connection with the entry into the Business Combination Agreement, DT and T-Mobile USA entered into a Financing Matters Agreement, dated as of April 29, 2018, pursuant to which DT agreed, among other things, to consent to the incurrence by T-Mobile USA of secured debt in connection with and after the consummation of the Merger. In connection with receiving the requisite consents, we made upfront payments to DT of $7 million during the second quarter of 2018. These payments were recognized as a reduction to Long-term debt to affiliates in our Condensed Consolidated Balance Sheets. See Note 9 - Debt for further information.

On May 18, 2018, under the terms and conditions described in the Consent Solicitation Statement dated as of May 14, 2018, (the “Consent Solicitation Statement”) we obtained consents necessary to effect certain amendments to certain existing debt of us and our subsidiaries. In connection with receiving the requisite consents, we made upfront payments to third-party note holders of approximately $31 million during the second quarter of 2018. These payments were recognized as a reduction to Long-term debt. We paid third-party bank fees associated with obtaining the requisite consents of $6 million during the second quarter of 2018, which we recognized as Selling, general and administrative expenses in our Condensed Consolidated Statements of Comprehensive Income.

Under the terms of Business Combination Agreement, Sprint may be required to reimburse us for 33% of the upfront consent and related bank fees we paid, or $14 million, if the Business Combination Agreement is terminated. We have not accrued the reimbursement of these fees as of September 30, 2018. On May 18, 2018, Sprint also obtained consents necessary to effect certain amendments to certain existing debt of it and its subsidiaries. In connection with receiving the requisite consents, Sprint’s made upfront payments to third-party note holders and related bank fees of $241 million during the second quarter of 2018. Under the terms of Business Combination Agreement, we may also be required to reimburse Sprint for 67% of the upfront consent and related bank fees it paid, or $161 million, if the Business Combination Agreement is terminated. We have not accrued these fees as of September 30, 2018.

For the three and nine months ended September 30, 2018, we recognized costs associated with the Transactions of $53 million and $94 million, respectively. These costs generally included bank fees associated with obtaining the requisite consents on debt to third parties, consulting and legal fees and were recognized as Selling, general and administrative expenses in our Condensed Consolidated Statements of Comprehensive Income.

The consummation of the Transactions is subject to regulatory approvals and certain other customary closing conditions. The transaction is expected to close during the first half of 2019. The Business Combination Agreement contains certain termination rights for both Sprint and us. If we terminate the Business Combination Agreement in connection with a failure to satisfy the closing condition related to specified minimum credit ratings for the combined company on the closing date of the Merger

Index for Notes to the Condensed Consolidated Financial Statements

(after giving effect to the Merger) from at least two of the three credit rating agencies, then in certain circumstances, we may be required to pay Sprint an amount equal to $600 million.

On June 18, 2018, we filed the Public Interest Statement and applications for approval of our Merger with Sprint with the Federal Communications Commission (the “FCC”). On July 18, 2018, the FCC issued a Public Notice formally accepting our applications and establishing a period for public comment. On September 11, 2018, the FCC issued a letter informing us it is pausing its informal 180-day transaction shot clock to allow for a thorough review by FCC staff and third parties of newly-submitted and anticipated modeling provided by us and Sprint.

On July 30, 2018, we filed a registration statement on Form S-4 with the SEC related to the Merger. The registration statement became effective on October 29, 2018.

Acquisition of Layer3 TV

On January 22, 2018, we completed our acquisition of television innovator Layer3 TV for cash consideration of $318 million. The consideration included a $5 million payment that was made after the closing date in the second quarter of 2018. Upon closing of the transaction, Layer3 TV became a wholly-owned consolidated subsidiary. Layer3 TV acquires and distributes digital entertainment programming primarily through the internet to residential customers, offering direct to home digital television and multi-channel video programming distribution services. This transaction represented an opportunity to acquire a complementary service to our existing wireless service to advance our video strategy.

We accounted for the purchase of Layer3 TV as a business combination. Costs related to this acquisition were immaterial to our Condensed Consolidated Statements of Comprehensive Income. The grant-date fair value of cash-based and share-based incentive compensation awards attributable to post-combination services was approximately $37 million.

The following table shows the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed and the resultant purchase price allocation:



(in millions)	January 22, 2018
Assets acquired
Cash and cash equivalents	$	2
Other current assets	14
Property and equipment, net	11
Intangible assets	100
Goodwill	218
Deferred tax assets	2
Total assets acquired	$	347
Liabilities assumed
Accounts payable and accrued liabilities	$	27
Short-term debt	2
Total liabilities assumed	29
Total consideration transferred	$	318

We recognized a liability of $21 million within Accounts payable and accrued liabilities in our Condensed Consolidated Balance Sheets and an associated indemnification asset of $12 million in our Condensed Consolidated Balance Sheets related to minimum commitments under acquired content agreements. As of September 30, 2018, the $12 million has been received.

Goodwill of $218 million is calculated as the excess of the purchase price paid over the net assets acquired. The goodwill recorded as part of the Layer3 TV acquisition primarily reflects industry knowledge of the retained management team, as well as intangible assets that do not qualify for separate recognition. None of the goodwill is deductible for tax purposes. See Note 6 - Goodwill for further information.

As part of the transaction, we acquired an identifiable intangible asset of developed technology with an estimated fair value of $100 million, which is being amortized on a straight-line basis over a useful life of 5 years.

The financial results from the acquisition of Layer3 TV since the closing date through September 30, 2018 were not material to our Condensed Consolidated Statements of Comprehensive Income.

Acquisition of Iowa Wireless

On January 1, 2018 (the “IWS Acquisition Date”), we closed on our previously announced Unit Purchase Agreement to acquire the remaining equity in IWS, a 54% owned unconsolidated subsidiary, for a purchase price of $25 million. We accounted for our acquisition of IWS as a business combination.

Prior to the IWS Acquisition Date, we accounted for our previously-held investment in IWS under the equity method as we had significant influence, but not control. Authoritative guidance on accounting for business combinations requires that an acquirer re-measure its previously held equity interest in the acquiree at its acquisition date fair value and recognize the resulting gain or loss in earnings. As such, we valued our previously held equity interest in IWS at $56 million as of the IWS Acquisition Date and recognized a gain of $15 million.

The following table highlights the consideration transferred, the fair value of our previously held equity interest and bargain purchase:



(in millions)	January 1, 2018
Consideration transferred:
Cash paid	$	25
Previously held equity interest:
Acquisition date fair value of previously held equity interest	56
Bargain purchase gain	25
Net assets acquired	$	106

As part of the acquisition of IWS, we recognized a bargain purchase gain of approximately $25 million, which represents the fair value of the identifiable net assets acquired, primarily IWS spectrum licenses, in excess of the purchase price and fair value of our previously held equity interest. We were in a favorable position to acquire the remaining shares of IWS as a result of our previously held 54% equity interest in IWS, an unprofitable business with valuable spectrum holdings.

The following table shows the amounts recognized as of the IWS Acquisition Date for each major class of assets acquired and liabilities assumed and the resultant purchase price allocation:



(in millions)	January 1, 2018
Assets acquired
Current assets
Cash and cash equivalents	$	3
Accounts receivable, net	6
Equipment installment plan receivables, net	3
Inventories	1
Other current assets	2
Total current assets	15
Property and equipment, net	36
Spectrum licenses	87
Total assets acquired	$	138
Liabilities assumed
Accounts payable and accrued liabilities	$	6
Deferred revenue	2
Total current liabilities	8
Deferred tax liabilities	17
Other long-term liabilities	7
Total long-term liabilities	24
Net assets acquired	$	106

We included both the gain on our previously held equity interest in IWS and the bargain purchase gain within Other income (expense), net for the nine months ended September 30, 2018.

Pro forma information

The acquisitions of Layer3 TV and IWS were not material to our prior period consolidated results on a pro forma basis.

Note 4 – Receivables and Allowance for Credit Losses

Our portfolio of receivables is comprised of two portfolio segments, accounts receivable and EIP receivables. Our accounts receivable segment primarily consists of amounts currently due from customers, including service and leased device receivables, other carriers and third-party retail channels.

Based upon customer credit profiles, we classify the EIP receivables segment into two customer classes of “Prime” and “Subprime.” Prime customer receivables are those with lower delinquency risk and Subprime customer receivables are those with higher delinquency risk. Customers may be required to make a down payment on their equipment purchases. In addition, certain customers within the Subprime category are required to pay an advance deposit.

To determine a customer’s credit profile, we use a proprietary credit scoring model that measures the credit quality of a customer at the time of application for wireless communications service using several factors, such as credit bureau information, consumer credit risk scores and service plan characteristics.

The following table summarizes the EIP receivables, including imputed discounts and related allowance for credit losses:



(in millions)	September 30, 2018			December 31, 2017
EIP receivables, gross	$	3,978		$	3,960
Unamortized imputed discount	(273		)	(264		)
EIP receivables, net of unamortized imputed discount	3,705			3,696
Allowance for credit losses	(116		)	(132		)
EIP receivables, net	$	3,589		$	3,564
Classified on the balance sheet as:
Equipment installment plan receivables, net	$	2,366		$	2,290

EIP receivables, net	$	3,589		$	3,564

To determine the appropriate level of the allowance for credit losses, we consider a number of credit quality indicators, including historical credit losses and timely payment experience as well as current collection trends such as write-off frequency and severity, aging of the receivable portfolio, credit quality of the customer base and other qualitative factors such as macro-economic conditions.

We write off account balances if collection efforts are unsuccessful and the receivable balance is deemed uncollectible, based on customer credit quality and the aging of the receivable.

For EIP receivables, subsequent to the initial determination of the imputed discount, we assess the need for and, if necessary, recognize an allowance for credit losses to the extent the amount of estimated probable losses on the gross EIP receivable balances exceed the remaining unamortized imputed discount balances.

The EIP receivables had weighted average effective imputed interest rates of 10.2% and 9.6% as of September 30, 2018 and December 31, 2017, respectively.

Note 5 – Sales of Certain Receivables

We have entered into transactions to sell certain service and EIP accounts receivable. The transactions, including our continuing involvement with the sold receivables and the respective impacts to our condensed consolidated financial statements, are described below.

Sales of Service Receivables

Overview of the Transaction

In 2014, we entered into an arrangement to sell certain service accounts receivable on a revolving basis and in November 2016, the arrangement was amended to increase the maximum funding commitment to $950 million (the “service receivable sale arrangement”) and extend the scheduled expiration date to March 2018. In February 2018, the service receivable sale arrangement was again amended to extend the scheduled expiration date to March 2019. In April 2018, the service receivable sale arrangement was again amended to update certain terms and covenants contained therein to make them consistent with analogous terms and covenants in the documentation of our other financing arrangements. As of September 30, 2018 and December 31, 2017, the service receivable sale arrangement provided funding of $830 million and $880 million, respectively. Sales of receivables occur daily and are settled on a monthly basis. The receivables consist of service charges currently due from customers and are short-term in nature.

In connection with the service receivable sale arrangement, we formed a wholly-owned subsidiary, which qualifies as a bankruptcy remote entity, to sell service accounts receivable (the “Service BRE”). The Service BRE does not qualify as a VIE, and due to the significant level of control we exercise over the entity, it is consolidated. Pursuant to the arrangement, certain of our wholly-owned subsidiaries transfer selected receivables to the Service BRE. The Service BRE then sells the receivables to an unaffiliated entity (the “Service VIE”), which was established to facilitate the sale of beneficial ownership interests in the receivables to certain third parties.

Index for Notes to the Condensed Consolidated Financial Statements

Variable Interest Entity

We determined that the Service VIE qualifies as a VIE as it lacks sufficient equity to finance its activities. We have a variable interest in the Service VIE but are not the primary beneficiary as we lack the power to direct the activities that most significantly impact the Service VIE’s economic performance. Those activities include committing the Service VIE to legal agreements to purchase or sell assets, selecting which receivables are purchased in the service receivable sale arrangement, determining whether the Service VIE will sell interests in the purchased service receivables to other parties, funding of the entity and servicing of receivables. We do not hold the power to direct the key decisions underlying these activities. For example, while we act as the servicer of the sold receivables, which is considered a significant activity of the Service VIE, we are acting as an agent in our capacity as the servicer and the counterparty to the service receivable sale arrangement has the ability to remove us as the servicing agent of the receivables at will with no recourse available to us. As we have determined we are not the primary beneficiary, the balances and results of the Service VIE are not included in our condensed consolidated financial statements.

The following table summarizes the carrying amounts and classification of assets, which consists primarily of the deferred purchase price and liabilities included in our Condensed Consolidated Balance Sheets that relate to our variable interest in the Service VIE:



(in millions)	September 30, 2018		December 31, 2017
Other current assets	$	299	$	236
Accounts payable and accrued liabilities	11		25
Other current liabilities	174		180

Sales of EIP Receivables

Overview of the Transaction

In 2015, we entered into an arrangement to sell certain EIP accounts receivable on a revolving basis and in August 2017, the EIP sale arrangement was amended to reduce the maximum funding commitment to $1.2 billion (the “EIP sale arrangement”) and extend the scheduled expiration date to November 2018. In December 2017, the EIP sale arrangement was again amended to increase the maximum funding commitment to $1.3 billion. In April 2018, the EIP sale arrangement was again amended to update certain terms and covenants contained therein to make them consistent with analogous terms and covenants in the documentation of our other financing arrangements. As of both September 30, 2018 and December 31, 2017, the EIP sale arrangement provided funding of $1.3 billion. Sales of EIP receivables occur daily and are settled on a monthly basis. The receivables consist of customer EIP balances, which require monthly customer payments for up to 24 months.

In October 2018, we amended and restated the EIP sale arrangement to, among other things, extend the scheduled expiration date to November 2020 and expand the types of EIP receivables that may be sold.

In connection with this EIP sale arrangement, we formed a wholly-owned subsidiary, which qualifies as a bankruptcy remote entity (the “EIP BRE”). Pursuant to the EIP sale arrangement, our wholly-owned subsidiary transfers selected receivables to the EIP BRE. The EIP BRE then sells the receivables to a non-consolidated and unaffiliated third-party entity for which we do not exercise any level of control, nor does the third-party entity qualify as a VIE.

Variable Interest Entity

We determined that the EIP BRE is a VIE as its equity investment at risk lacks the obligation to absorb a certain portion of its expected losses. We have a variable interest in the EIP BRE and determined that we are the primary beneficiary based on our ability to direct the activities which most significantly impact the EIP BRE’s economic performance. Those activities include selecting which receivables are transferred into the EIP BRE and sold in the EIP sale arrangement and funding of the EIP BRE. Additionally, our equity interest in the EIP BRE obligates us to absorb losses and gives us the right to receive benefits from the EIP BRE that could potentially be significant to the EIP BRE. Accordingly, we determined that we are the primary beneficiary, and include the balances and results of operations of the EIP BRE in our condensed consolidated financial statements.

Index for Notes to the Condensed Consolidated Financial Statements



(in millions)	September 30, 2018		December 31, 2017
Other current assets	$	405	$	403
Other assets	98		109
Other long-term liabilities	22		3

In addition, the EIP BRE is a separate legal entity with its own separate creditors who will be entitled, prior to any liquidation of the EIP BRE, to be satisfied prior to any value in the EIP BRE becoming available to us. Accordingly, the assets of the EIP BRE may not be used to settle our general obligations and creditors of the EIP BRE have limited recourse to our general credit.

Sales of Receivables

The transfers of service receivables and EIP receivables to the non-consolidated entities are accounted for as sales of financial assets. Once identified for sale, the receivable is recorded at the lower of cost or fair value. Upon sale, we derecognize the net carrying amount of the receivables.

We recognize the cash proceeds received upon sale in Net cash provided by operating activities in our Condensed Consolidated Statements of Cash Flows. We recognize proceeds net of the deferred purchase price, consisting of a receivable from the purchasers that entitles us to certain collections on the receivables. We recognize the collection of the deferred purchase price in Net cash provided by investing activities in our Condensed Consolidated Statements of Cash Flows as Proceeds related to beneficial interests in securitization transactions.

The deferred purchase price represents a financial asset that is primarily tied to the creditworthiness of the customers and which can be settled in such a way that we may not recover substantially all of our recorded investment, due to default by the customers on the underlying receivables. We elected, at inception, to measure the deferred purchase price at fair value with changes in fair value included in Selling, general and administrative expense in our Condensed Consolidated Statements of Comprehensive Income. The fair value of the deferred purchase price is determined based on a discounted cash flow model which uses primarily unobservable inputs (Level 3 inputs), including customer default rates. As of September 30, 2018 and December 31, 2017, our deferred purchase price related to the sales of service receivables and EIP receivables was $800 million and $745 million, respectively.

The following table summarizes the impacts of the sale of certain service receivables and EIP receivables in our Condensed Consolidated Balance Sheets:



(in millions)	September 30, 2018			December 31, 2017
Derecognized net service receivables and EIP receivables	$	2,682		$	2,725
Other current assets	704			639

Of which:
Change in net cash proceeds during the year-to-date period	(143		)	28
Net cash proceeds funded by reinvested collections	2,058			2,030

We recognized losses from sales of receivables of $48 million and $67 million for the three months ended September 30, 2018 and 2017, respectively, and $127 million and $242 million for the nine months ended September 30, 2018 and 2017, respectively. These losses from sales of receivables were recognized in Selling, general and administrative expense in our Condensed Consolidated Statements of Comprehensive Income. Losses from sales of receivables include adjustments to the receivables’ fair values and changes in fair value of the deferred purchase price.

Index for Notes to the Condensed Consolidated Financial Statements

Continuing Involvement

Pursuant to the sale arrangements described above, we have continuing involvement with the service receivables and EIP receivables we sell as we service the receivables and are required to repurchase certain receivables, including ineligible receivables, aged receivables and receivables where write-off is imminent. We continue to service the customers and their related receivables, including facilitating customer payment collection, in exchange for a monthly servicing fee. As the receivables are sold on a revolving basis, the customer payment collections on sold receivables may be reinvested in new receivable sales. While servicing the receivables, we apply the same policies and procedures to the sold receivables as we apply to our owned receivables, and we continue to maintain normal relationships with our customers. Pursuant to the EIP sale arrangement, under certain circumstances, we are required to deposit cash or replacement EIP receivables primarily for contracts terminated by customers under our JUMP! Program.

In addition, we have continuing involvement with the sold receivables as we may be responsible for absorbing additional credit losses pursuant to the sale arrangements. Our maximum exposure to loss related to the involvement with the service receivables and EIP receivables sold under the sale arrangements was $1.3 billion as of September 30, 2018. The maximum exposure to loss, which is a required disclosure under GAAP, represents an estimated loss that would be incurred under severe, hypothetical circumstances whereby we would not receive the deferred purchase price portion of the contractual proceeds withheld by the purchasers and would also be required to repurchase the maximum amount of receivables pursuant to the sale arrangements without consideration for any recovery. As we believe the probability of these circumstances occurring is remote, the maximum exposure to loss is not an indication of our expected loss.

Note 6 - Goodwill

The changes in the carrying amount of goodwill for the nine months ended September 30, 2018, are as follows:



(in millions)	Goodwill
Historical goodwill	$	12,449
Accumulated impairment losses at December 31, 2017	(10,766		)
Balance as of December 31, 2017	1,683
Goodwill from acquisition of Layer3 TV	218
Balance as of September 30, 2018	$	1,901
Accumulated impairment losses at September 30, 2018	$	(10,766	)

On January 22, 2018, we completed our acquisition of television innovator Layer3 TV. This purchase was accounted for as a business combination resulting in $218 million in goodwill. Layer3 TV is a separate reporting unit and the acquired goodwill will be tested for impairment at this level. See Note 3 - Business Combinations for additional information.

Note 7 – Spectrum License Transactions

The following table summarizes our spectrum license activity for the nine months ended September 30, 2018:



(in millions)	Spectrum Licenses
Balance at December 31, 2017	$	35,366
Spectrum license acquisitions	137
Costs to clear spectrum	50
Balance at September 30, 2018	$	35,553

We had the following spectrum license transactions in the nine months ended September 30, 2018:


•	We recorded spectrum licenses received as part of our acquisition of the remaining equity interest in IWS at their estimated fair value of approximately $87 million. See Note 3 - Business Combinations for further information.


•	We closed on multiple spectrum purchase agreements in which we acquired total spectrum licenses of approximately $50 million for cash consideration.


•	In September 2018, we signed a reciprocal long-term lease agreement with Sprint in which both parties have the right to use a portion of spectrum owned by the other party. This executory agreement does not qualify as an acquisition of

Index for Notes to the Condensed Consolidated Financial Statements

spectrum licenses, and we have not capitalized amounts related to the lease. The reciprocal long-term lease is a distinct transaction from the Merger. See Note 15 – Commitments and Contingencies for further information.

Note 8 – Fair Value Measurements

The carrying values of cash and cash equivalents, accounts receivable, accounts receivable from affiliates, accounts payable, and borrowings under our senior secured revolving credit facility with DT, our majority stockholder, approximate fair value due to the short-term maturities of these instruments.

Deferred Purchase Price Assets

In connection with the sales of certain service and EIP receivables pursuant to the sale arrangements, we have deferred purchase price assets measured at fair value that are based on a discounted cash flow model using unobservable Level 3 inputs, including customer default rates. See Note 5 – Sales of Certain Receivables for further information.

The carrying amounts and fair values of our assets measured at fair value on a recurring basis included in our Condensed Consolidated Balance Sheets were as follows:



	Level within the Fair Value Hierarchy	September 30, 2018				December 31, 2017
(in millions)	Level within the Fair Value Hierarchy	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Assets:
Deferred purchase price assets	3	$	800	$	800	$	745	$	745

Long-term Debt

The fair value of our Senior Notes to third parties was determined based on quoted market prices in active markets, and therefore was classified as Level 1 within the fair value hierarchy. The fair values of our Senior Notes to affiliates, Incremental Term Loan Facility to affiliates and Senior Reset Notes to affiliates were determined based on a discounted cash flow approach using market interest rates of instruments with similar terms and maturities and an estimate for our standalone credit risk. Accordingly, our Senior Notes to affiliates, Incremental Term Loan Facility to affiliates and Senior Reset Notes to affiliates were classified as Level 2 within the fair value hierarchy.

Although we have determined the estimated fair values using available market information and commonly accepted valuation methodologies, considerable judgment was required in interpreting market data to develop fair value estimates for the Senior Notes to affiliates, Incremental Term Loan Facility to affiliates and Senior Reset Notes to affiliates. The fair value estimates were based on information available as of September 30, 2018 and December 31, 2017. As such, our estimates are not necessarily indicative of the amount we could realize in a current market exchange.

The carrying amounts and fair values of our short-term and long-term debt included in our Condensed Consolidated Balance Sheets were as follows:



	Level within the Fair Value Hierarchy	September 30, 2018				December 31, 2017
(in millions)	Level within the Fair Value Hierarchy	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Liabilities:
Senior Notes to third parties	1	$	10,949	$	11,168	$	11,910	$	12,540

(2)	Cash for the premium portion of the redemption price set forth in the indenture governing the DT Senior Reset Notes, plus accrued but unpaid interest on the DT Senior Reset Notes to, but not including, the exchange date.

Incremental Term Loan Facility

In March 2018, we amended the terms of the Incremental Term Loan Facility. Following this amendment, the applicable margin payable on LIBOR indexed loans is 1.50% under the $2.0 billion Incremental Term Loan Facility maturing on November 9, 2022 and 1.75% under the $2.0 billion Incremental Term Loan Facility maturing on January 31, 2024. The amendment also modified the Incremental Term Loan Facility to (i) include a soft-call prepayment premium of 1.00% of the outstanding principal amount of the loans under the Incremental Term Loan Facility payable to DT upon certain refinancings of such loans by us with lower priced debt prior to a date that is six months after March 29, 2018 and (ii) update certain covenants and other provisions to make them substantially consistent, subject to certain additional carve outs, with our most recently publicly issued notes. No issuance fees were incurred related to this debt agreement for the three and nine months ended September 30, 2018.

Revolving Credit Facility

In January 2018, we utilized proceeds under our revolving credit facility with DT to redeem $1.0 billion in aggregate principal amount of our 6.125% Senior Notes due 2022 and for general corporate purposes. On January 29, 2018, the proceeds utilized under our revolving credit facility with DT were repaid. The proceeds and borrowings from the revolving credit facility are presented in Proceeds from borrowing on revolving credit facility and Repayments of revolving credit facility within Net cash used in financing activities in our Condensed Consolidated Statements of Cash Flows. As of September 30, 2018 and December 31, 2017, there were no outstanding borrowings under the revolving credit facility.

In March 2018, we amended the terms of (a) our Secured Revolving Credit Facility and (b) our Unsecured Revolving Credit Facility. Following these amendments, (i) the range of applicable margin payable under the Secured Revolving Credit Facility is 1.05% to 1.80%, (ii) the range of the applicable margin payable under the Unsecured Revolving Credit Facility is 2.05% to 3.05%, (iii) the range of the undrawn commitment fee applicable to the Secured Revolving Credit Facility is 0.25% to 0.45%, (iv) the range of the undrawn commitment fee applicable to the Unsecured Revolving Credit Facility is 0.20% to 0.575% and (v) the maturity date of the revolving credit facility with DT is December 29, 2020. The amendments also modify the facility to update certain covenants and other provisions to make them substantially consistent, subject to certain additional carve outs, with our most recently publicly issued notes.

Commitment Letter

Index for Notes to the Condensed Consolidated Financial Statements

set forth therein, including consummation of the Merger. The proceeds of the debt financing provided for in the Commitment Letter will be used to refinance certain existing debt of us, Sprint and our and Sprint’s respective subsidiaries and for post-closing working capital needs of the combined company. In connection with the financing provided for in the Commitment Letter, we expect to incur certain fees if the Merger closes, including fees for the financial institutions structuring and providing the commitments for the secured term loan facility, secured revolving loan facility and the secured bridge loan, and certain take-out fees associated with the issuance of permanent secured bond debt in lieu of the secured bridge loan. We expect to incur up to approximately $275 million in fees if the Merger were to close on or after January 29, 2019. The fees increase to up to approximately $340 million if the closing date occurs on or after April 29, 2019. We have not accrued these fees as of September 30, 2018. We also may be required to draw down on the $7.0 billion secured term loan facility on May 1, 2019, and would be required to place the proceeds in escrow and pay interest thereon until the Merger closes.

Financing Matters Agreement

In connection with the entry into the Business Combination Agreement, DT and T-Mobile USA entered into a Financing Matters Agreement, dated as of April 29, 2018 (the “Financing Matters Agreement”). Pursuant to the Financing Matters Agreement, DT agreed, among other things, to consent to the incurrence by T-Mobile USA of secured debt in connection with and after the consummation of the Merger, and to provide a lock up on sales thereby as to certain senior notes of T-Mobile USA held thereby. In addition, T-Mobile USA agreed, among other things, to repay and terminate, upon closing of the Merger, the Incremental Term Loan Facility and the revolving credit facility of T-Mobile USA which are provided by DT, as well as $2.0 billion of T-Mobile USA’s 5.300% Senior Notes due 2021 and $2.0 billion of T-Mobile USA’s 6.000% Senior Notes due 2024. In addition, T-Mobile USA and DT agreed, upon closing of the Merger, to amend the $1.25 billion of T-Mobile USA’s 5.125% Senior Notes due 2025 and $1.25 billion of T-Mobile USA’s 5.375% Senior Notes due 2027 to change the maturity dates thereof to April 15, 2021 and April 15, 2022, respectively. In connection with receiving the requisite consents, we made upfront payments to DT of $7 million during the second quarter of 2018. These payments were recognized as a reduction to Long-term debt to affiliates in our Condensed Consolidated Balance Sheets. If the Merger is consummated, we will make additional payments for requisite consents to DT of $20 million. We have not accrued these additional payments as of September 30, 2018.

Consents on Debt to Third Parties

On May 18, 2018, under the terms and conditions described in the Consent Solicitation Statement, we obtained consents necessary to effect certain amendments to our Senior Notes to third parties in connection with the Business Combination Agreement. Pursuant to the Consent Solicitation Statement, third-party notes holders agreed, among other things, to consent to increasing the amount of Secured Indebtedness under Credit Facilities that can be incurred from the greater of $9 billion and 150% of Consolidated Cash Flow to the greater of $9 billion and an amount that would not cause the Secured Debt to Cash Flow Ratio (calculated net of cash and cash equivalents) to exceed 2.00x (the “Ratio Secured Debt Proposed Amendments”) and in each case as such capitalized term is defined in the Indenture. In connection with receiving the requisite consents for the Ratio Secured Debt Proposed Amendments, we made upfront payments to third-party note holders of $17 million during the second quarter of 2018. These payments were recognized as a reduction to Long-term debt in our Condensed Consolidated Balance Sheets. These upfront payments increased the effective interest rate of the related debt.

In addition, note holders agreed, among other things, to allow certain entities related to Sprint’s existing spectrum securitization notes program (“Existing Sprint Spectrum Program”) to be non-guarantor Restricted Subsidiaries, provided that the principal amount of the spectrum notes issued and outstanding under the Existing Sprint Spectrum Program does not exceed $7.0 billion and that the principal amount of such spectrum notes reduces the amount available under the Credit Facilities ratio basket, and to revise the definition of GAAP to mean generally accepted accounting principles in effect from time to time, unless the Company elects to “freeze” GAAP as of any date, and to exclude the effect of the changes in the accounting treatment of lease obligations (the “Existing Sprint Spectrum and GAAP Proposed Amendments,” and together with the Ratio Secured Debt Proposed Amendments, the “Proposed Amendments”). In connection with receiving the requisite consents for the Existing Sprint Spectrum and GAAP Proposed Amendments, we made upfront payments to third-party note holders of $14 million during the second quarter of 2018. These payments were recognized as a reduction to Long-term debt in our Condensed Consolidated Balance Sheets. These upfront payments increased the effective interest rate of the related debt.

In connection with obtaining the requisite consents, on May 20, 2018, T-Mobile USA, the guarantors and Deutsche Bank Trust Company Americas, as trustee, executed and delivered the 37^th supplemental indenture to the Indenture, pursuant to which, with respect to each of the Notes, the Proposed Amendments will become effective immediately prior to the consummation of the Merger.

We paid third-party bank fees associated with obtaining the requisite consents related to the Proposed Amendments of $6

Index for Notes to the Condensed Consolidated Financial Statements

million during the second quarter of 2018, which we recognized as Selling, general and administrative expenses in our Condensed Consolidated Statements of Comprehensive Income. If the Merger is consummated, we will make additional payments to third-party note holders for requisite consents related to the Ratio Secured Debt Proposed Amendments of up to $54 million and additional payments to third-party note holders for requisite consents related to the Existing Sprint Spectrum and GAAP Proposed Amendments of up to $41 million. We have not accrued these payments as of September 30, 2018.

Note 10 - Employee Compensation and Benefit Plans

On February 14, 2018, our Board of Directors adopted, and on June 13, 2018, our stockholders approved an amendment (the “Amendment”) to the 2013 Omnibus Incentive Plan (as amended, the “Plan”) which increased the number of shares authorized for issuance under the Plan by 18,500,000 shares. On June 18, 2018, we filed a Form S-8 to register a total of 19,345,005 shares of common stock pursuant to the Plan, representing those covered by the Amendment, certain other predecessor plans, and certain equity arrangements assumed in connection with the acquisition of Layer3 TV in January 2018.

During the nine months ended September 30, 2018, we granted or assumed an aggregate of 5,897,295 restricted stock units (“RSUs”) and restricted stock awards (“RSAs”) to eligible employees, certain non-employee directors, and eligible key executives, which primarily included annual awards.

During the nine months ended September 30, 2018, we granted an aggregate of 3,185,853 performance-based restricted stock units (“PRSUs”) to eligible key executives, which primarily included annual awards. In addition, in connection with the entry into a Business Combination Agreement to merge with Sprint, in April 2018 we granted an aggregate of 1,210,710 PRSUs to certain executive officers.

As discussed in Note 3 - Business Combinations, in January 2018, we completed our acquisition of Layer3 TV. The grant-date fair value of share-based incentive compensation awards attributable to post-combination services was approximately $30 million.

Stock-based compensation expense and related income tax benefits were as follows:

Note 11 - Revenue from Contracts with Customers

Disaggregation of Revenue

We provide wireless communication services to three primary categories of customers:


•	Branded postpaid customers generally include customers that are qualified to pay after receiving wireless communication services utilizing phones, mobile broadband devices (including tablets), DIGITS, SyncUP DRIVE^TM or other devices including wearables;


•	Branded prepaid customers generally include customers who pay for wireless communication services in advance. Our branded prepaid customers include customers of T-Mobile and Metro^TM by T-Mobile (“Metro”); and


•	Wholesale customers include Machine-to-Machine (“M2M”) and Mobile Virtual Network Operator (“MVNO”) customers that operate on our network but are managed by wholesale partners.

Branded postpaid service revenues, including branded postpaid phone revenues and branded postpaid other revenues, were as follows:



	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2018		2017		2018		2017
Branded postpaid service revenues
Branded postpaid phone revenues	$	4,955	$	4,626	$	14,658	$	13,691
Branded postpaid other revenues	289		294		820		774
Total branded postpaid service revenues	$	5,244	$	4,920	$	15,478	$	14,465

We operate as a single operating segment. The balances presented within each revenue line item in our Condensed Consolidated Statements of Comprehensive Income represent categories of revenue from contracts with customers disaggregated by type of product and service. Service revenues also include revenues earned for providing value added services to customers, such as handset insurance services. Revenue generated from the lease of mobile communication devices and accessories is included within Equipment revenues in our Condensed Consolidated Statements of Comprehensive Income.

Equipment revenues from the lease of mobile communication devices and accessories were as follows:



	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2018		2017		2018		2017
Equipment revenues from the lease of mobile communication devices and accessories	$	176	$	159	$	524	$	717

Index for Notes to the Condensed Consolidated Financial Statements

Contract Balances

The opening and closing balances of our contract asset and contract liability balances from contracts with customers as of January 1, 2018 and September 30, 2018, were as follows:



(in millions)	Contract Assets Included in Other Current Assets			Contract Liabilities Included in Deferred Revenue
Balance as of January 1, 2018	$	140		$	718
Balance as of September 30, 2018	52			649
Change	$	(88	)	$	(69	)

Contract assets primarily represent revenue recognized for equipment sales with promotional bill credits offered to customers that are paid over time and are contingent on the customer maintaining a service contract. The change in the contract asset balance includes customer activity related to new promotions, offset by billings on existing contracts and impairment which is recognized as bad debt expense.

Contract liabilities are recorded when fees are collected, or we have an unconditional right to consideration (a receivable) in advance of delivery of goods or services. The change in contract liabilities is primarily related to customer activity associated with our prepaid plans including the receipt of cash payments and the satisfaction of our performance obligations.

Revenues for the three and nine months ended September 30, 2018, include the following:



(in millions)	Three Months Ended September 30, 2018		Nine Months Ended September 30, 2018
Amounts included in the January 1, 2018 contract liability balance	$	23	$	582
Amounts associated with performance obligations satisfied in previous periods	28		2

Remaining Performance Obligations

As of September 30, 2018, the aggregate amount of transaction price allocated to remaining service performance obligations for branded postpaid contracts with promotional bill credits that result in an extended service contract is $379 million. We expect to recognize this revenue as service is provided over the extended contract term in the next 24 months.

Certain of our wholesale, roaming and other service contracts include variable consideration based on usage. This variable consideration has been excluded from the disclosure of remaining performance obligations. As of September 30, 2018, the aggregate amount of the contractual minimum consideration allocated to remaining service performance obligations for wholesale, roaming and other service contracts is $272 million, $1.1 billion and $911 million for 2018, 2019 and 2020 and beyond, respectively. These contracts have a remaining duration of less than one year to seven years.

Information about remaining performance obligations that are part of a contract that has an original expected duration of one year or less have been excluded from the above, which primarily consists of monthly service contracts. The aggregate amount of the transaction price allocated to remaining service performance obligations includes the estimated amount to be invoiced to the customer.

Contract Costs

The total deferred incremental costs to obtain contracts balance as of September 30, 2018 was $519 million. Deferred contract costs incurred to obtain postpaid service contracts are amortized over a period of 24 months. The amortization period is monitored to reflect any significant change in assumptions. Amortization of deferred contract costs was $79 million and $171 million for the three and nine months ended September 30, 2018, respectively.

The deferred contract cost asset is assessed for impairment on a periodic basis. There were no impairment losses recognized on deferred contract cost assets for the three and nine months ended September 30, 2018.

Note 12 – Repurchases of Common Stock

2017 Stock Repurchase Program

On December 6, 2017, our Board of Directors authorized a stock repurchase program for up to $1.5 billion of our common stock through December 31, 2018 (the “2017 Stock Repurchase Program”). During the nine months ended September 30, 2018, we repurchased an additional 16.7 million shares of our common stock for $1.1 billion. There were no repurchases during the three months ended September 30, 2018. From the inception of the 2017 Stock Repurchase Program through April 27, 2018, we repurchased 23.7 million shares of our common stock at an average price per share of $63.07 for a total purchase price of $1.5 billion. Repurchased shares are retired. The 2017 Stock Repurchase Program completed on April 29, 2018.

2018 Stock Repurchase Program

On April 27, 2018, our Board of Directors authorized an increase in the total stock repurchase program to $9.0 billion, consisting of the $1.5 billion in repurchases previously completed and for up to an additional $7.5 billion of repurchases of our common stock, allocated as up to $500 million of shares of common stock through December 31, 2018, up to $3.0 billion of shares of common stock for the year ending December 31, 2019 and up to $4.0 billion of shares of common stock for the year ending December 31, 2020, with any authorized but unutilized repurchase capacity for any of the foregoing periods increasing the authorized repurchase capacity for the succeeding period by the amount of such unutilized repurchase capacity. The additional $7.5 billion repurchase authorization is contingent upon the termination of the Business Combination Agreement and the abandonment of the transactions contemplated under the Business Combination Agreement.

Under the repurchase program, repurchases can be made from time to time using a variety of methods, which may include open market purchases, privately negotiated transactions or otherwise, all in accordance with the rules of the SEC and other applicable legal requirements. The specific timing, price and size of purchases will depend on prevailing stock prices, general economic and market conditions, and other considerations. The repurchase program does not obligate us to acquire any particular amount of common stock, and the repurchase program may be suspended or discontinued at any time at our discretion. Repurchased shares are retired.

Stock Purchases by Affiliate

In the first quarter of 2018, DT, our majority stockholder and an affiliated purchaser, purchased 3.3 million additional shares of our common stock at an aggregate market value of $200 million in the public market or from other parties, in accordance with the rules of the SEC and other applicable legal requirements. There were no purchases in the second and third quarters of 2018. We did not receive proceeds from these purchases.

Note 13 – Income Taxes

Within our Condensed Consolidated Statements of Comprehensive Income, we recorded Income tax expense of $335 million and $356 million for the three months ended September 30, 2018 and 2017, respectively, and $831 million and $618 million for the nine months ended September 30, 2018 and 2017, respectively.

The change for the three and nine months ended September 30, 2018, was primarily impacted by a reduction in the federal corporate income tax rate from 35% to 21% provided by the Tax Cuts and Jobs Act, which took effect January 1, 2018. This reduction was partially offset by higher income before taxes. The change in Income tax expense for the nine months ended September 30, 2018 additionally reflected $289 million in tax benefits recognized in the nine months ended September 30, 2017 related to a reduction in the valuation allowance against deferred tax assets in certain state jurisdictions that did not impact 2018.

Income tax expense for the three and nine months ended September 30, 2018 was additionally impacted by an increase of $115 million from a change in tax regime in certain state tax jurisdictions as well as an increase from non-deductible costs associated with the Transactions. These increases were partially offset by income tax benefits of $63 million from a change in tax status of certain subsidiaries, including a related $28 million reduction in valuation allowance against deferred tax assets in certain state jurisdictions. We will continue to monitor positive and negative evidence related to the utilization of the remaining deferred tax assets for which a valuation allowance continues to be provided. It is possible that our valuation allowance may change within the next twelve months.

Note 14 – Earnings Per Share

The computation of basic and diluted earnings per share was as follows:



	Three Months Ended September 30,					Nine Months Ended September 30,
(in millions, except shares and per share amounts)	2018		2017			2018		2017

Potentially dilutive securities:
Outstanding stock options and unvested stock awards	537,810		—			779,644		4,760

As of September 30, 2018, we had authorized 100 million shares of 5.50% mandatory convertible preferred stock series A, with a par value of $0.00001 per share. There were zero and 20 million preferred shares outstanding as of September 30, 2018 and September 30, 2017, respectively.

On December 15, 2017, 20 million shares of our preferred stock converted to approximately 32 million shares of our common stock at a conversion rate of 1.6119 shares of common stock for each share of previously outstanding preferred stock and certain cash-in-lieu of fractional shares.

Potentially dilutive securities were not included in the computation of diluted earnings per share if to do so would have been anti-dilutive.

Note 15 – Commitments and Contingencies

Commitments

Operating Leases

We have non-cancellable operating leases for cell sites, switch sites, retail stores and office facilities with contractual terms expiring through 2028. The majority of cell site leases have an initial non-cancelable term of five to ten years with several renewal options. In addition, we have operating leases for dedicated transportation lines with varying expiration terms through 2027. Our commitments under these leases are approximately $2.6 billion for the year ending September 30, 2019, $4.5 billion in total for the years ending September 30, 2020 and 2021, $3.0 billion in total for the years ending September 30, 2022 and 2023 and $3.2 billion in total for years thereafter.

Purchase Commitments

We have commitments for non-dedicated transportation lines with varying expiration terms through 2029. In addition, we have commitments to purchase and lease spectrum licenses, wireless devices, network services, equipment, software, marketing sponsorship agreements and other items in the ordinary course of business, with various terms through 2029. These amounts are not reflective of our entire anticipated purchases under the related agreements but are determined based on the non-cancelable quantities or termination amounts to which we are contractually obligated.

We have contractual obligations to purchase and lease certain goods and services from various other parties. Our purchase obligations are approximately $2.5 billion for the year ending September 30, 2019, $2.7 billion in total for the years ending September 30, 2020 and 2021, $1.9 billion in total for the years ending September 30, 2022 and 2023 and $1.3 billion in total for the years thereafter.

In June 2018, we entered into an agreement for the purchase of network equipment totaling approximately $3.5 billion. Based on unavoidable spend, the minimum commitment under this agreement is $201 million as of September 30, 2018.

In September 2018, we amended an agreement with a third party to increase the total amount of network equipment to purchase by approximately $3.5 billion. Based on unavoidable spend, the minimum commitment under this agreement is $201 million as of September 30, 2018.

In September 2018, we signed a reciprocal long-term spectrum lease with Sprint that included a total commitment of $533 million and an offsetting amount to be received from Sprint for the lease of our spectrum. Lease payments are expected to begin in the fourth quarter of 2018. The reciprocal long-term lease is a distinct transaction from the Merger.

In October 2018, we entered into agreements with a third-party associated with a device upgrade program, trade-in services, and device protection products and services offered to our mobile communications customers, with initial terms of one to three years. Device protection products and services include reinsurance for device insurance policies and extended warranty contracts, mobile security applications, and technical support services.

Renewable Energy Purchase Agreements

In June 2018, T-Mobile USA entered into a renewable energy purchase agreement (the “REPA”) with a third party. The REPA is based on the expected operation of a wind energy-generating facility located in Illinois and will remain in effect until the 15^th anniversary of the facility’s entry into commercial operation. Commercial operation of the facility is expected to occur by the end of 2020. The REPA consists of two components: (1) an energy forward agreement that is net settled based on energy prices and the energy output generated by the facility and (2) a commitment to purchase environmental attributes (“EACs”) in the same amount as the energy output generated by the facility. T-Mobile USA will net settle the forward agreement and acquire the EACs monthly by paying, or receiving, an aggregate net payment based on two variables (1) the facility’s energy output, which has an estimated maximum capacity of approximately 150 megawatts and (2) the difference between (a) an initial fixed price, subject to annual escalation, and (b) current local marginal energy prices during the monthly settlement period. We have determined that the REPA does not meet the definition of a derivative because the expected energy output of the facility may not be reliably estimated (the arrangement lacks a notional amount). The REPA does not contain any unconditional purchase obligations because amounts under the agreement are not fixed and determinable. Our participation in the REPA did not require an upfront investment or capital commitment. We do not control the activities that most significantly impact the energy-generating facility, nor do we receive specific energy output from it. No amounts were settled under the REPA during the nine months ended September 30, 2018.

Index for Notes to the Condensed Consolidated Financial Statements

In August 2018, T-Mobile USA entered into a REPA with a third party. The REPA is based on the expected operation of a solar photovoltaic electrical generation facility located in Virginia and will remain in effect until the twentieth anniversary of the facility’s entry into commercial operation. Commercial operation of the facility is expected to occur by the end of 2020. The REPA consists of an energy forward agreement that is net settled based on energy prices and the energy output generated by the facility. The REPA does not contain a defined commitment, volume, or penalty amount. T-Mobile USA will acquire the EACs and net settle on the fixed-for-variable energy cost swap on the basis of the energy output at an initial fixed price, subject to annual escalation. We have determined that the REPA does not meet the definition of a derivative because the expected energy output of the facility may not be reliably estimated (the arrangement lacks a notional amount). The REPA does not contain any unconditional purchase obligations because amounts under the agreement are not fixed and determinable. Our participation in the REPA did not require an upfront investment or capital commitment. We do not control the activities that most significantly impact the energy-generating facility, nor do we receive specific energy output from it. No amounts were settled under the REPA during the nine months ended September 30, 2018.

In October 2018, T-Mobile USA entered into two REPAs with third parties that are based on the expected operation of solar photovoltaic electrical generation facilities located in Virginia and will remain in effect until the fifteenth anniversary of the respective facilities’ entry into commercial operation. Commercial operation of the facilities is expected to occur by the end of 2019 and 2020, respectively. The REPAs do not contain a defined commitment, volume, or penalty amount.

Contingencies and Litigation

Litigation Matters

We are involved in various lawsuits and disputes, claims, government agency investigations and enforcement actions, and other proceedings (“Litigation Matters”) that arise in the ordinary course of business, which include claims of patent infringement (most of which are asserted by non-practicing entities primarily seeking monetary damages), class actions, and proceedings to enforce FCC rules and regulations. The Litigation Matters described above have progressed to various stages and some of them may proceed to trial, arbitration, hearing or other adjudication that could result in fines, penalties, or awards of monetary or injunctive relief in the coming 12 months if they are not otherwise resolved. We have established an accrual with respect to certain of these matters, where appropriate, which is reflected in the condensed consolidated financial statements but that we do not consider, individually or in the aggregate, material. An accrual is established when we believe it is both probable that a loss has been incurred and an amount can be reasonably estimated. For other matters, where we have not determined that a loss is probable or because the amount of loss cannot be reasonably estimated, we have not recorded an accrual due to various factors typical in contested proceedings, including but not limited to: uncertainty concerning legal theories and their resolution by courts or regulators; uncertain damage theories and demands; and a less than fully developed factual record. While we do not expect that the ultimate resolution of these proceedings, individually or in the aggregate, will have a material adverse effect on our financial position, an unfavorable outcome of some or all of these proceedings could have a material adverse impact on results of operations or cash flows for a particular period. This assessment is based on our current understanding of relevant facts and circumstances. As such, our view of these matters is subject to inherent uncertainties and may change in the future.

Note 16 – Subsequent Events

In October 2018, we received reimbursement payments of $63 million from our insurance carriers related to hurricane impacts. The balance was accrued as a receivable as of September 30, 2018. See Note 2 - Significant Transactions for further information.

In October 2018, we entered into several interest rate lock transactions with multiple banks with an aggregate notional amount of $9.6 billion. These agreements will be used to mitigate variability in future cash flows resulting from changes in interest rates prior to the issuance of long-term debt.

In October 2018, T-Mobile USA entered into two REPAs with third parties. See Note 15 - Commitments and Contingencies for further information.

Note 17 – Guarantor Financial Information

Pursuant to the applicable indentures and supplemental indentures, the long-term debt to affiliates and third parties issued by T-Mobile USA (“Issuer”) is fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by T-Mobile (“Parent”) and certain of the Issuer’s 100% owned subsidiaries (“Guarantor Subsidiaries”).

In January 2018, T-Mobile USA and certain of its affiliates, as guarantors, issued (i) $1.0 billion of public 4.500% Senior Notes due 2026 and (ii) $1.5 billion of public 4.750% Senior Notes due 2028.

In April 2018, T-Mobile USA and certain of its affiliates, as guarantors, issued (i) $1.0 billion in aggregate principal amount of 4.500% Senior Notes due 2026 and (ii) $1.5 billion in aggregate principal amount of 4.750% Senior Notes due 2028. Additionally, T-Mobile USA and certain of its affiliates, as guarantors, redeemed through net settlement, (i) the $1.25 billion in aggregate principal amount of 8.097% Senior Reset Notes due 2021 and (ii) $1.25 billion in aggregate principal amount of 8.195% Senior Reset Notes due 2022.

See Note 9 - Debt for further information.

The guarantees of the Guarantor Subsidiaries are subject to release in limited circumstances only upon the occurrence of certain customary conditions. The indentures and credit facilities governing the long-term debt contain covenants that, among other things, limit the ability of the Issuer and the Guarantor Subsidiaries to: incur more debt; pay dividends and make distributions; make certain investments; repurchase stock; create liens or other encumbrances; enter into transactions with affiliates; enter into transactions that restrict dividends or distributions from subsidiaries; and merge, consolidate, or sell, or otherwise dispose of, substantially all of their assets. Certain provisions of each of the credit facilities, indentures and supplemental indentures relating to the long-term debt restrict the ability of the Issuer to loan funds or make payments to Parent. However, the Issuer and Guarantor Subsidiaries are allowed to make certain permitted payments to the Parent under the terms of the indentures and the supplemental indentures.

During the preparation of the condensed consolidating financial information of T-Mobile US, Inc. and Subsidiaries for the year ended December 31, 2017, it was determined that certain intercompany advances were misclassified in Net cash provided by (used in) operating activities and Net cash provided by (used in) financing activities in the Condensed Consolidating Statement of Cash Flows Information for the three and nine months ended September 30, 2017, as filed in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2017. We have revised the Issuer, Guarantor Subsidiaries and Non-Guarantor Subsidiaries columns of the Condensed Consolidating Statement of Cash Flows Information to reclassify

Index for Notes to the Condensed Consolidated Financial Statements

•	adverse economic or political conditions in the U.S. and international markets;


•	competition, industry consolidation, and changes in the market for wireless services, which could negatively affect our ability to attract and retain customers;

Overview

The objectives of our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) are to provide users of our condensed consolidated financial statements with the following:


•	A narrative explanation from the perspective of management of our financial condition, results of operations, cash flows, liquidity and certain other factors that may affect future results;


•	Context to the financial statements; and


•	Information that allows assessment of the likelihood that past performance is indicative of future performance.

Our MD&A is provided as a supplement to, and should be read together with, our unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2018, included in Part I, Item 1 of this Form 10-Q and audited consolidated financial statements included in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2017 (together with our Current Report on Form 8-K filed June 18, 2018, which is incorporated by reference herein). Except as expressly stated, the financial condition and results of operations discussed throughout our MD&A are those of T-Mobile US, Inc. and its consolidated subsidiaries.

Business Overview

In August 2018, we introduced Un-carrier Next, a new initiative that radically changes the structure of our customer service department and solves several significant pain points for customers. Postpaid customers will get directly through to a human when they call customer support, and that human will be one member of a “Team of Experts” devoted to that customer and other customers in their geographic region. No bots, no bouncing, no BS.

Table of Contents

Un-carrier Next also provided T-Mobile customers exclusive access to a free one-year Pandora Plus subscription via the T-Mobile Tuesdays App on August 28, 2018. In addition, we announced an exclusive multi-year partnership with Live Nation, the world’s largest live entertainment company, giving Un-carrier customers rock star status at Live Nation amphitheater and arena concerts, including access to last-minute reserve seats in sold-out sections and discounted tickets.

In September 2018, we announced the rebranding of our prepaid brand, MetroPCS, as Metro^TM by T-Mobile (“Metro”) and introduced new unlimited rate plans with tiers that feature added benefits of Google One and Amazon Prime as well as an expanded selection of the latest and greatest smartphones. Gone are the outdated perceptions that prepaid service is synonymous with limited coverage, cheap flip phones or bad credit.

Proposed Sprint Transaction

On April 29, 2018, we entered into a business combination agreement (“Business Combination Agreement”) with Sprint Corporation (“Sprint”) to merge in an all-stock transaction at a fixed exchange ratio of 0.10256 shares of T-Mobile common stock for each share of Sprint common stock, or 9.75 shares of Sprint common stock for each share of T-Mobile common stock (the “Merger,” and together with the other transactions contemplated by the Business Combination Agreement, the “Transactions”). The combined company will be named “T-Mobile,” and as a result of the Merger, is expected to be able to rapidly launch a nationwide 5G network, accelerate innovation and increase competition in the U.S. wireless, video and broadband industries. Immediately following the Merger, it is anticipated that DT and SoftBank Group Corp. will hold, directly or indirectly, on a fully diluted basis, approximately 41.7% and 27.3%, respectively, of the outstanding T-Mobile common stock, with the remaining approximately 31.0% of the outstanding T-Mobile common stock held by other stockholders, based on closing share prices and certain other assumptions as of the date of the Business Combination Agreement. The Merger is subject to regulatory approvals and certain other customary closing conditions and is expected to close in the first half of 2019.

For more information regarding our Business Combination Agreement, see Note 3 - Business Combinations in the Notes

to the Condensed Consolidated Financial Statements.

Acquisitions

•

On January 1, 2018, we closed on our previously announced Unit Purchase Agreement to acquire the remaining equity in Iowa Wireless Services, LLC (“IWS”), a 54% owned unconsolidated subsidiary, for a purchase price of $25 million. We accounted for our acquisition of IWS as a business combination and recognized a bargain purchase gain of approximately $25 million as part of our purchase price allocation and a gain on our previously held equity interest of approximately $15 million in Other income, net in the nine months ended September 30, 2018.

•

On January 22, 2018, we completed our acquisition of television innovator Layer3 TV, Inc. (“Layer3 TV”) for cash consideration of $318 million. Upon closing of the transaction, Layer3 TV became a wholly-owned consolidated subsidiary. Layer3 TV acquires and distributes digital entertainment programming primarily through the internet to residential customers, offering direct to home digital television and multi-channel video programming distribution services. This transaction represented an opportunity to acquire a complementary service to our existing wireless service to advance our video strategy. We accounted for the purchase of Layer3 TV as a business combination and recognized $218 million of goodwill as part of our purchase price allocation.

For more information regarding our acquisitions, see Note 3 - Business Combinations in the Notes to the Condensed Consolidated Financial Statements.

Accounting Pronouncements Adopted During the Current Year

Revenue Recognition

On January 1, 2018, we adopted ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” and all the related amendments (collectively, the “new revenue standard”). See Note 11 - Revenue from Contracts with Customers of the Notes to the Condensed Consolidated Financial Statements for information regarding the new revenue standard and Note 1 - Summary of Significant Accounting Policies of the Notes to the Condensed Consolidated Financial Statements for information regarding recently issued accounting standards.

Table of Contents

The impact of our adoption of the new revenue standard is presented in Note 1 – Summary of Significant Accounting Policies and in the following table which presents a comparison of selected financial information under both the new revenue standard and the previous revenue standard for the three and nine months ended September 30, 2018:

Statement of Cash Flows

On January 1, 2018, we adopted ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments” (the “new cash flow standard”) which impacted the presentation of our cash flows related to our beneficial interests in securitization transactions, which is the deferred purchase price, resulting in a reclassification of cash inflows from Operating activities to Investing activities of approximately $1.3 billion and $1.1 billion for the three months ended September 30, 2018 and 2017, respectively, and $4.0 billion and $3.1 billion for the nine months ended September 30, 2018 and 2017, respectively, in our Condensed Consolidated Statements of Cash Flows. The new cash flow standard also impacted the presentation of our cash payments for debt prepayment and debt extinguishment costs, resulting in a reclassification of cash outflows from Operating activities to Financing activities of $212 million and $188 million for the nine months ended September 30, 2018 and 2017, respectively, in our Condensed Consolidated Statements of Cash Flows. There were no cash payments for debt prepayment and debt extinguishment costs during the three months ended September 30, 2018 and 2017. We have applied the new cash flow standard retrospectively to all periods presented.

For additional information regarding the new cash flow standard and the impact of our adoptions, see Note 1 - Summary of Significant Accounting Policies of the Notes to the Condensed Consolidated Financial Statements.

Financial Instruments

In January 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-01, “Financial Instruments (Topic 825): Recognition and Measurement of Financial Assets and Financial Liabilities.” The standard addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The standard became effective for us, and we adopted the standard, on January 1, 2018. The standard requires the impact of adoption to be recorded to retained earnings under a modified retrospective approach. The implementation of this standard did not have a material impact on our condensed consolidated financial statements.

Income Taxes

In October 2016, the FASB issued ASU 2016-16, “Accounting for Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory.” The standard requires that the income tax impact of intra-entity sales and transfers of property, except for inventory, be recognized when the transfer occurs. The standard became effective for us, and we adopted the standard, on January 1, 2018. The standard requires any deferred taxes not yet recognized on intra-entity transfers to be recorded to retained earnings under a modified retrospective approach. The implementation of this standard did not have a material impact on our condensed consolidated financial statements.

Results of Operations

Highlights for the three months ended September 30, 2018, compared to the same period in 2017


•	Total revenues of $10.8 billion for the three months ended September 30, 2018 increased $820 million, or 8%, primarily driven by growth in service and equipment revenues as further discussed below.

•

Service revenues of $8.1 billion for the three months ended September 30, 2018 increased $437 million, or 6%, primarily due to growth in our average branded customer base driven by the continued growth in existing and Greenfield markets, the growing success of new customer segments such as T-Mobile for Business, T-Mobile ONE Unlimited 55+, and T-Mobile ONE Military, along with lower churn, growth in connected devices and the success of our Metro brand.

•

Equipment revenues of $2.4 billion for the three months ended September 30, 2018 increased $273 million, or 13%, primarily due to higher average revenue per device sold and the positive impact from the new revenue standard of $105 million, partially offset by a decrease in the number of devices sold, excluding purchased lease devices, lower volumes of purchased leased devices at the end of the lease term, and a decrease in the proceeds from liquidation of returned customer handsets.

•

Operating income of $1.4 billion for the three months ended September 30, 2018 increased $117 million, or 9%, primarily due to higher Total revenues, partially offset by higher Cost of equipment sales, Depreciation and amortization and Selling, general and administrative expenses. Operating income for the three months ended September 30, 2018 included the positive impacts from the adoption of the new revenue standard of $136 million and insurance reimbursements related to the hurricanes, net of costs of $138 million as well as the negative impact of costs associated with the Transactions of $53 million. Operating income also included the negative impact from hurricanes of $148 million and gains on disposal of spectrum licenses of $29 million for the three months ended September 30, 2017.

•

Performance Measures

In managing our business and assessing financial performance, we supplement the information provided by our financial statements with other operating or statistical data and non-GAAP financial measures. These operating and financial measures are utilized by our management to evaluate our operating performance and, in certain cases, our ability to meet liquidity requirements. Although companies in the wireless industry may not define each of these measures in precisely the same way, we believe that these measures facilitate comparisons with other companies in the wireless industry on key operating and financial measures.

Total Customers

A customer is generally defined as a SIM number with a unique T-Mobile identifier which is associated with an account that generates revenue. Branded customers generally include customers that are qualified either for postpaid service utilizing phones, DIGITS or connected devices which includes tablets, wearables and SyncUp DRIVE^TM, where they generally pay after receiving service, or prepaid service, where they generally pay in advance. Wholesale customers include Machine-to-Machine (“M2M”) and Mobile Virtual Network Operator (“MVNO”) customers that operate on our network but are managed by wholesale partners.

•	The change for the three months ended September 30, 2018 was primarily due to higher MVNO net customer additions.


•	The change for the nine months ended September 30, 2018 was primarily from lower deactivations driven by the removal of Lifeline program customers.

Customers Per Account

Customers per account is calculated by dividing the number of branded postpaid customers as of the end of the period by the number of branded postpaid accounts as of the end of the period. An account may include branded postpaid phone customers and branded postpaid other customers which includes DIGITS and connected devices such as tablets, wearables and SyncUp DRIVE^TM. We believe branded postpaid customers per account provides management, investors and analysts with useful information to evaluate our branded postpaid customer base on a per account basis.

The following table sets forth the branded postpaid customers per account:



	September 30, 2018	September 30, 2017	Change
	September 30, 2018	September 30, 2017	#	%
Branded postpaid customers per account	2.99	2.92	0.07	2	%

Branded postpaid customers per account increased 2% primarily from promotional activities targeting families and the success of connected devices.

Churn

Churn represents the number of customers whose service was disconnected as a percentage of the average number of customers during the specified period. The number of customers whose service was disconnected is presented net of customers that subsequently have their service restored within a certain period of time. We believe that churn provides management, investors and analysts with useful information to evaluate customer retention and loyalty.

The following table sets forth the churn:



	Three Months Ended September 30,				Bps Change	Nine Months Ended September 30,				Bps Change
	2018		2017		Bps Change	2018		2017		Bps Change
Branded postpaid phone churn	1.02	%	1.23	%	-21 bps	1.02	%	1.18	%	-16 bps
Branded prepaid churn	4.12	%	4.25	%	-13 bps	3.95	%	4.06	%	-11 bps

Branded postpaid phone churn decreased 21 basis points for the three months ended and 16 basis points for the nine months ended September 30, 2018, primarily from increased customer satisfaction and loyalty from ongoing improvements to network quality, industry-leading customer service and the overall value of our offerings in the marketplace.

Branded prepaid churn decreased 13 basis points for the three months ended and 11 basis points for the nine months ended September 30, 2018, primarily due to the continued impact from the optimization of our third-party distribution channels which was substantially completed during the first quarter of 2017, partially offset by higher deactivations from a growing customer base and increased competitive activity in the marketplace.

Average Revenue Per User, Average Billings Per User

Average Revenue Per User (“ARPU”) represents the average monthly service revenue earned from customers. We believe ARPU provides management, investors and analysts with useful information to assess and evaluate our service revenue realization per customer and assist in forecasting our future service revenues generated from our customer base. Branded postpaid phone ARPU excludes Branded postpaid other customers and related revenues which includes DIGITS and connected devices such as tablets, wearables and SyncUp DRIVE^TM.

Average Billings Per User (“ABPU”) represents the average monthly customer billings, including monthly lease revenues and EIP billings before securitization, per customer. We believe branded postpaid ABPU provides management, investors and analysts with useful information to evaluate average branded postpaid customer billings as it is indicative of estimated cash collections, including device financing payments, from our customers each month.

Branded postpaid phone ARPU decreased $0.76, or 2%, for the three months ended and $0.73, or 2%, for the nine months ended September 30, 2018.

The decrease for the three months ended September 30, 2018 was primarily due to the continued adoption of tax inclusive plans, including the growing success of new customer segments such as T-Mobile for Business, T-Mobile ONE Unlimited 55+ and T-Mobile ONE Military as well as a reduction in certain non-recurring charges including the noncash net benefit from Data Stash. These decreases were partially offset by a net reduction in service promotional activities.

The decrease for the nine months ended September 30, 2018 was primarily due to the continued adoption of tax inclusive plans, including from the growing success of new customer segments such as T-Mobile for Business, T-Mobile ONE Unlimited 55+ and T-Mobile ONE Military and a reduction in certain non-recurring charges including the noncash net benefit from Data Stash. The negative impact of the new revenue standard was $0.07. These decreases were partially offset by a net reduction in service promotional activities.

We continue to expect that Branded postpaid phone ARPU in full-year 2018 will be generally stable compared to full-year 2017, excluding the impact from the new revenue standard.

Branded Postpaid ABPU

Branded postpaid ABPU decreased $2.20, or 4%, for the three months ended and $2.00, or 3%, for the nine months ended September 30, 2018.

The decrease for the three months ended September 30, 2018 was primarily from:


•	Lower branded postpaid phone ARPU; and


•	Growth in the branded postpaid other customer base with a lower ARPU than branded postpaid phone.

The decrease for the nine months ended September 30, 2018 was primarily from:


•	Lower branded postpaid phone ARPU;

Branded Prepaid ARPU

Branded prepaid ARPU decreased $0.59, or 2%, for the three months ended and $0.14, for the nine months ended September 30, 2018, primarily from dilution from promotional rate plans.

Adjusted EBITDA

Adjusted EBITDA represents earnings before Interest expense, net of Interest income, Income tax expense, Depreciation and amortization, non-cash Stock-based compensation and certain income and expenses not reflective of T-Mobile’s operating performance. Net income margin represents Net income divided by Service revenues. Adjusted EBITDA margin represents Adjusted EBITDA divided by Service revenues.

Adjusted EBITDA is a non-GAAP financial measure utilized by our management to monitor the financial performance of our operations. We use Adjusted EBITDA internally as a metric to evaluate and compensate our personnel and management for their performance, and as a benchmark to evaluate our operating performance in comparison to our competitors. Management believes analysts and investors use Adjusted EBITDA as a supplemental measure to evaluate overall operating performance and facilitate comparisons with other wireless communications companies because it is indicative of our ongoing operating performance and trends by excluding the impact of interest expense from financing, non-cash depreciation and amortization from capital investments, non-cash stock-based compensation, network decommissioning costs and costs related to the Transactions, as they are not indicative of our ongoing operating performance, as well as certain other nonrecurring income and expenses. Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation or as a substitute for income from operations, net income or any other measure of financial performance reported in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”).

The following table illustrates the calculation of Adjusted EBITDA and reconciles Adjusted EBITDA to Net income, which we consider to be the most directly comparable GAAP financial measure:

Liquidity and Capital Resources

Our principal sources of liquidity are our cash and cash equivalents and cash generated from operations, proceeds from issuance of long-term debt and common stock, capital leases, the sale of certain receivables, financing arrangements of vendor payables which effectively extend payment terms and secured and unsecured revolving credit facilities with DT. Upon consummation of the Transactions, we will incur substantial third-party indebtedness which will increase our future financial commitments, including aggregate interest payments on higher total indebtedness, and may adversely impact our liquidity. Further, the incurrence of additional indebtedness may inhibit our ability to incur new debt under the terms governing our existing and future indebtedness, which may make it more difficult for us to incur new debt in the future to finance our business strategy.

Cash Flows

The following is an analysis of our cash flows for the three and nine months ended September 30, 2018 and 2017:

Operating Activities

Net cash provided by operating activities decreased $338 million, or 27%, for the three months ended and $21 million, or 1%, for the nine months ended September 30, 2018.

The decrease for the three months ended September 30, 2018 was primarily from:


•	A $707 million increase in net cash outflows from changes in working capital, including a paydown of Accounts payable and accrued liabilities of $253 million, a $228 million build up of Inventories with the launch of the new iPhone generation and a $216 million increase in Accounts receivable; partially offset by


•	A $245 million increase to Net income; and


•	A $124 million increase in net non-cash adjustments to Net income, primarily due to higher Depreciation and amortization, partially offset by lower Deferred income tax expense and Bad debt expense.

The decrease for the nine months ended September 30, 2018 was primarily from:


•	A $876 million increase in net cash outflows from changes in working capital including a paydown of Accounts payable and accrued liabilities of $765 million and a $571 million increase in Accounts receivable, partially offset by changes in EIP receivables; This increase in net cash outflows was partially offset by

The use of cash for the three months ended September 30, 2018 was primarily from:


•	$1.4 billion in Purchases of property and equipment, including capitalized interest, primarily driven by growth in network build as we continued deployment of low band spectrum, including 600 MHz; partially offset by


•	$1.3 billion in proceeds related to beneficial interest in securitization transactions.

The use of cash for the nine months ended September 30, 2018 was primarily from:


•	$4.4 billion in Purchases of property and equipment, including capitalized interest, primarily driven by growth in network build as we continued deployment of low band spectrum, including beginning deployment of 600 MHz; and


•	$338 million of cash consideration paid, net of cash acquired, for the acquisitions of Layer3 and IWS; partially offset by


•	$4.0 billion in proceeds related to beneficial interest in securitization transactions.

Financing Activities

Net cash used in financing activities increased $409 million, or 117%, to a use of $758 million for the three months ended and $2.3 billion, or 323%, to a use of $3.0 billion for the nine months ended September 30, 2018.

The use of cash for the three months ended September 30, 2018 was primarily from:


•	$2.1 billion for Repayments of our revolving credit facility;


•	$246 million for Repayments of short-term debt for purchases of inventory, property and equipment, net; and


•	$181 million for Repayments of capital lease obligations; partially offset by


•	$1.8 billion in Proceeds from borrowing on our revolving credit facility.

The use of cash for the nine months ended September 30, 2018 was primarily from:


•	$6.1 billion for Repayments of our revolving credit facility;


•	$3.3 billion for Repayments of long-term debt;


•	$1.1 billion for Repurchases of common stock; and


•	$508 million for Repayments of capital lease obligations; partially offset by


•	$6.1 billion in Proceeds from borrowing on our revolving credit facility; and


•	$2.5 billion in Proceeds from issuance of long-term debt.

Cash and Cash Equivalents

As of September 30, 2018, our Cash and cash equivalents were $329 million.

Free Cash Flow

Free Cash Flow represents net cash provided by operating activities less payments for purchases of property and equipment, including proceeds related to beneficial interests in securitization transactions and less cash payments for debt prepayment or debt extinguishment costs. Free Cash Flow is a non-GAAP financial measure utilized by our management, investors and

Table of Contents

analysts of T-Mobile’s financial information to evaluate cash available to pay debt and provide further investment in the business.

In the first quarter of 2018, we redefined our non-GAAP financial measure Free Cash Flow to reflect the adoption of ASU 2016-15 to present cash flows on a consistent basis for investor transparency. We have applied the change in definition retrospectively in the table below, which illustrates the calculation of Free Cash Flow and reconciles Free Cash Flow to Net cash provided by operating activities, which we consider to be the most directly comparable GAAP financial measure:



	Three Months Ended September 30,						Change					Nine Months Ended September 30,						Change

Free Cash Flow	$	890		$	921		$	(31	)	(3	)%	$	2,332		$	1,588		$	744		47	%

Free Cash Flow decreased $31 million, or 3%, for the three months ended September 30, 2018, primarily from:


•	Lower net cash provided by operating activities, as described above; partially offset by


•	Higher proceeds related to our deferred purchase price from securitization transactions; and


•	Lower purchases of property and equipment. Cash purchases of property and equipment include capitalized interest of $101 million and $29 million for the three months ended September 30, 2018 and 2017, respectively.

Free Cash Flow increased $744 million, or 47%, for the nine months ended September 30, 2018, primarily from:


•	Higher proceeds related to our deferred purchase price from securitization transactions; partially offset by


•	Higher Purchases of property and equipment, net of capitalized interest of $246 million and $111 million for the nine months ended September 30, 2018 and 2017, respectively.

Debt

As of September 30, 2018, our total debt was $27.4 billion, excluding our tower obligations, of which $26.6 billion was classified as long-term debt. Significant debt-related activity for the nine months ended September 30, 2018 included:

Commitment Letter

In connection with the entry into the Business Combination Agreement, T-Mobile USA entered into a commitment letter, dated as of April 29, 2018 (as amended and restated on May 15, 2018, the “Commitment Letter”), with certain financial institutions named therein that have committed to provide up to $38.0 billion in secured and unsecured debt financing, including a $4.0 billion secured revolving credit facility, a $7.0 billion secured term loan facility, a $19.0 billion secured bridge loan facility and an $8.0 billion unsecured bridge loan facility. Following the receipt of the debt consents described below, as permitted by the terms of the commitment letter, on May 22, 2018, T-Mobile USA reallocated the entire $8.0 billion unsecured bridge loan facility to be part of the secured bridge loan facility, increasing the size of the secured bridge loan facility to $27.0 billion, and subsequently on June 6, 2018, reduced the initial aggregate commitment under the secured bridge facility by $8.0 billion, such that the remaining size of the secured bridge facility is currently $19.0 billion and total committed financing is currently $30.0 billion. The funding of the debt facilities provided for in the Commitment Letter is subject to the satisfaction of the conditions set forth therein, including consummation of the Merger. The proceeds of the debt financing provided for in the Commitment Letter will be used to refinance certain existing debt of us, Sprint and our and Sprint’s respective subsidiaries and for post-closing working capital needs of the combined company. In connection with the financing provided for in the Commitment Letter, we expect to incur certain fees if the Merger closes, including fees for the financial institutions structuring and providing the commitments for the secured term loan facility, secured revolving loan facility and the secured bridge loan, and certain take-out fees associated with the issuance of permanent secured bond debt in lieu of the secured bridge loan. We expect to incur up to approximately $275 million in fees if the Merger were to close on or after January 29, 2019. The fees increase to up to approximately $340 million if the closing date occurs on or after April 29, 2019. We have not accrued these fees as of September 30, 2018. We also may be required to draw down on the $7.0 billion secured term loan facility on May 1, 2019, and would be required to place the proceeds in escrow and pay interest thereon until the Merger closes.

and that the principal amount of such spectrum notes reduces the amount available under the Credit Facilities ratio basket, and to revise the definition of GAAP to mean generally accepted accounting principles in effect from time to time, unless the Company elects to “freeze” GAAP as of any date, and to exclude the effect of the changes in the accounting treatment of lease obligations (the “Existing Sprint Spectrum and GAAP Proposed Amendments,” and together with the Ratio Secured Debt Proposed Amendments, the “Proposed Amendments”). In connection with receiving the requisite consents for the Existing Sprint Spectrum and GAAP Proposed Amendments, we made upfront payments to third-party note holders of $14 million during the second quarter of 2018. These payments were recognized as a reduction to Long-term debt in our Condensed Consolidated Balance Sheets. These upfront payments increased the effective interest rate of the related debt.

We paid third-party bank fees associated with obtaining the requisite consents related to the Proposed Amendments of $6 million during the second quarter of 2018, which we recognized as Selling, general and administrative expenses in our Condensed Consolidated Statements of Comprehensive Income. If the Merger is consummated, we will make additional payments to third-party note holders for requisite consents related to the Ratio Secured Debt Proposed Amendments of up to $54 million and additional payments to third-party note holders for requisite consents related to the Existing Sprint Spectrum and GAAP Proposed Amendments of up to $41 million. We have not accrued these payments as of September 30, 2018.

See Note 9 – Debt of the Notes to the Condensed Consolidated Financial Statements for further information.

We could seek additional sources of liquidity, including through the issuance of additional long-term debt in 2018, to continue to opportunistically acquire spectrum licenses or other assets in private party transactions or for the refinancing of existing long-term debt on an opportunistic basis. Excluding liquidity that could be needed for spectrum acquisitions or other assets, we expect our principal sources of funding to be sufficient to meet our anticipated liquidity needs for business operations for the next 12 months. Our intended use of any such funds is for general corporate purposes, including for capital expenditures, spectrum purchases, opportunistic investments and acquisitions, redemption of high yield callable debt and stock purchases.

We determine future liquidity requirements, for both operations and capital expenditures, based in large part upon projected financial and operating performance, and opportunities to acquire additional spectrum. We regularly review and update these projections for changes in current and projected financial and operating results, general economic conditions, the competitive landscape and other factors. There are a number of risks and uncertainties that could cause our financial and operating results and capital requirements to differ materially from our projections, which could cause future liquidity to differ materially from our assessment.

The indentures and credit facilities governing our long-term debt to affiliates and third parties, excluding capital leases, contain covenants that, among other things, limit the ability of the Issuer and the Guarantor Subsidiaries to: incur more debt; pay dividends and make distributions on our common stock; make certain investments; repurchase stock; create liens or other encumbrances; enter into transactions with affiliates; enter into transactions that restrict dividends or distributions from subsidiaries; and merge, consolidate, or sell, or otherwise dispose of, substantially all of their assets. Certain provisions of each of the credit facilities, indentures and supplemental indentures relating to the long-term debt to affiliates and third parties restrict the ability of the Issuer to loan funds or make payments to the Parent. However, the Issuer is allowed to make certain permitted payments to the Parent under the terms of each of the credit facilities, indentures and supplemental indentures relating to the long-term debt to affiliates and third parties. We were in compliance with all restrictive debt covenants as of September 30, 2018.

Capital Lease Facilities

We have entered into uncommitted capital lease facilities with certain partners, which provide us with the ability to enter into capital leases for network equipment and services. As of September 30, 2018, we have committed to $2.6 billion of capital leases under these capital lease facilities, of which $133 million and $451 million was executed during the three and nine months ended September 30, 2018, respectively. We expect to enter into up to an additional $449 million in capital lease commitments during 2018.

Table of Contents

Capital Expenditures

Our liquidity requirements have been driven primarily by capital expenditures for spectrum licenses and the construction, expansion and upgrading of our network infrastructure. Property and equipment capital expenditures primarily relate to our network transformation, including the build-out of 600 MHz low-band spectrum licenses. We expect cash purchases of property and equipment, excluding capitalized interest, to be at the high end of the range of $4.9 billion to $5.3 billion in 2018. This includes expenditures for 5G deployment. This does not include property and equipment obtained through capital lease agreements, leased wireless devices transferred from inventory or any additional purchases of spectrum licenses.

Share Repurchases

Related-Party Transactions

During the nine months ended September 30, 2018, we entered into certain debt related transactions with affiliates. See Note 9 – Debt of the Notes to the Condensed Consolidated Financial Statements for further information.

We also have related party transactions associated with DT or its affiliates in the ordinary course of business, including intercompany servicing and licensing.

Disclosure of Iranian Activities under Section 13(r) of the Securities Exchange Act of 1934

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the Exchange Act of 1934, as amended (“Exchange Act”). Section 13(r) requires an issuer to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with designated natural persons or entities involved in terrorism or the proliferation of weapons of mass destruction. Disclosure is required even where the activities, transactions or dealings are conducted outside the U.S. by non-U.S. affiliates in compliance with applicable law, and whether or not the activities are sanctionable under U.S. law.

As of the date of this report, we are not aware of any activity, transaction or dealing by us or any of our affiliates for the three months ended September 30, 2018, that requires disclosure in this report under Section 13(r) of the Exchange Act, except as set forth below with respect to affiliates that we do not control and that are our affiliates solely due to their common control with DT. We have relied upon DT for information regarding their activities, transactions and dealings.

DT, through certain of its non-U.S. subsidiaries, is party to roaming and interconnect agreements with the following mobile and fixed line telecommunication providers in Iran, some of which are or may be government-controlled entities: Gostaresh Ertebatat Taliya, Irancell Telecommunications Services Company (“MTN Irancell”), Telecommunication Kish Company, Mobile Telecommunication Company of Iran, and Telecommunication Infrastructure Company of Iran. For the three months ended September 30, 2018, gross revenues of all DT affiliates generated by roaming and interconnection traffic with Iran were less than $1 million and estimated net profits were less than $1 million.

Table of Contents

In addition, DT, through certain of its non-U.S. subsidiaries, operating a fixed line network in their respective European home countries (in particular Germany), provides telecommunications services in the ordinary course of business to the Embassy of Iran in those European countries. Gross revenues and net profits recorded from these activities for the three months ended September 30, 2018 were less than $0.1 million. We understand that DT intends to continue these activities.

Off-Balance Sheet Arrangements

We have arrangements, as amended from time to time, to sell certain EIP accounts receivable and service accounts receivable on a revolving basis as a source of liquidity. As of September 30, 2018, T-Mobile derecognized net receivables of $2.7 billion upon sale through these arrangements. See Note 5 – Sales of Certain Receivables of the Notes to the Condensed Consolidated Financial Statements for further information.

Critical Accounting Policies and Estimates

Preparation of our condensed consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of certain assets, liabilities, revenues and expenses, as well as related disclosure of contingent assets and liabilities. Except as described below, there have been no material changes to the critical accounting policies and estimates as previously disclosed in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2017.

The policy below is critical because it requires management to make difficult, subjective and complex judgments about matters that are inherently uncertain and because it is likely that materially different amounts would be reported under different conditions or using different assumptions. Actual results could differ from those estimates.

Management and the Audit Committee of the Board of Directors have reviewed and approved these critical accounting policies.

Revenue Recognition

Significant Judgments

The most significant judgments affecting the amount and timing of revenue from contracts with our customers include the following items:


•	For transactions where we recognize a significant financing component, judgment is required to determine the discount rate. For EIP sales, the discount rate used to adjust the transaction price primarily reflects current market interest rates and the estimated credit risk of the customer.


•	Our products are generally sold with a right of return, which is accounted for as variable consideration when estimating the amount of revenue to recognize. Expected device returns are estimated based on historical experience.

•


•	For capitalized contract costs, determining the amortization period as well as assessing the indicators of impairment may require significant judgment.


•	The determination of the standalone selling price for contracts that involve more than one product or service (or performance obligation) may require significant judgment.


•	The identification of distinct performance obligations within our service plans may require significant judgment.

Wireless Services Revenue

Table of Contents

services. Service contracts are billed monthly either in advance or arrears, or are prepaid. Generally, service revenue is recognized as we satisfy our performance obligation to transfer service to our customers. We typically satisfy our stand-ready performance obligations, including unlimited wireless services, evenly over the contract term. For usage-based and prepaid wireless services, we satisfy our performance obligations when services are rendered.

Federal Universal Service Fund and other regulatory fees are assessed by various governmental authorities in connection with the services we provide to our customers and included in Cost of services. When we separately bill and collect these regulatory fees from customers, they are recorded in Total service revenues in our Condensed Consolidated Statements of Comprehensive Income.

Equipment Revenues

We generate equipment revenues from the sale or lease of mobile communication devices and accessories. For performance obligations related to equipment contracts, we typically transfer control at a point in time when the device or accessory is delivered to, and accepted by, the customer or dealer. We have elected to account for shipping and handling activities that occur after control of the related good transfers as fulfillment activities instead of assessing such activities as performance obligations. We establish provisions for estimated device returns based on historical experience. Equipment sales not probable of collection are generally recorded as payments are received. Our assessment of collectibility considers contract terms such as down payments that reduce our exposure to credit risk.

In addition, for customers who enroll in our JUMP!^®program, we recognize a liability based on the estimated fair value of the specified-price trade-in right guarantee. The fair value of the guarantee is deducted from the transaction price under the new revenue standard, and the remaining transaction price is allocated to other elements of the contract, including service and equipment performance obligations. See “Guarantee Liabilities” in Note 1 - Summary of Significant Accounting Policies included in our Annual Report on Form 10-K for the year ended December 31, 2017.

Table of Contents

Contract Balances

Generally, T-Mobile devices and service plans are available at standard prices, which are maintained on price lists and published on our website and/or within our retail stores.

Contract assets are included in Other current assets and Other assets and contract liabilities are included in Deferred revenue in our Condensed Consolidated Balance Sheets.

Contract Modifications

Contract Costs

Incremental costs to obtain equipment contracts (e.g., commissions paid on device and accessory sales) are recognized when the equipment is transferred to the customer.

See Note 1 - Summary of Significant Accounting Policies and Note 11 - Revenue from Contracts with Customers of the Notes to the Condensed Consolidated Financial Statements for further information.

Accounting Pronouncements Not Yet Adopted

Item 3. Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to the interest rate risk as previously disclosed in Part II, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2017.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Table of Contents

We maintain disclosure controls and procedures designed to ensure information required to be disclosed in our periodic reports filed or submitted under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Our disclosure controls are also designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective, as of the end of the period covered by this Form 10-Q.

The certifications required by Section 302 of the Sarbanes-Oxley Act of 2002 are filed as exhibits 31.1 and 31.2, respectively, to this Form 10-Q.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act, during our most recently completed fiscal quarter that materially affected or are reasonably likely to materially affect our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

See Note 15 - Commitments and Contingencies of the Notes to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this Form 10-Q for information regarding certain legal proceedings in which we are involved.

Item 1A. Risk Factors

In addition to the other information contained in this Form 10-Q, the Risk Factors as previously disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2017, as supplemented by the Risk Factors included in Part II, Item 1A “Risk Factors” of our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2018, the following risk factors and the risk factors contained in the section entitled “Risk Factors” in the final joint consent solicitation/proxy statement of T-Mobile and Sprint dated October 29, 2018 forming part of our registration statement on Form S-4 (Registration No. 333-226435) filed with the SEC, should be considered carefully in evaluating T-Mobile. Our business, financial condition, liquidity, or operating results, as well as the price of our common stock and other securities, could be materially adversely affected by any of these risks.

We could be harmed by data loss or other security breaches, whether directly or by way of third parties.

Our business, like that of most retailers and wireless companies, involves the receipt, storage, and transmission of our customers’ confidential information, including sensitive personal information and payment card information, confidential information about our employees and suppliers, and other sensitive information about our Company, such as our business plans, transactions and intellectual property (“Confidential Information”). Unauthorized access to Confidential Information may be difficult to anticipate, detect, or prevent, particularly given that the methods of unauthorized access constantly change and evolve. We are subject to the threat of unauthorized access or disclosure of Confidential Information by state-sponsored parties, malicious actors, third parties or employees, errors or breaches by third-party suppliers, or other security incidents that could compromise the confidentiality and integrity of Confidential Information. In August 2018, we notified affected customers of an incident involving unauthorized access to certain customer contact information (not involving credit card information, financial data, social security numbers or passwords). While we do not believe the August 2018 security incident was material, we expect to continue to be the target of cyber-attacks, data breaches, or security incidents, which may in the future have a materially adverse effect on our business, reputation, financial condition, and operating results.

Cyber-attacks, such as denial of service and other malicious attacks, could disrupt our internal systems and applications, impair our ability to provide services to our customers, and have other adverse effects on our business and that of others who depend on our services. As a telecommunications carrier, we are considered a critical infrastructure provider and therefore may be more likely to be the target of such attacks. Such attacks against companies may be perpetrated by a variety of groups or persons,

Table of Contents

including those in jurisdictions where law enforcement measures to address such attacks are ineffective or unavailable, and such attacks may even be perpetrated by or at the behest of foreign governments.

In addition, we provide confidential, proprietary and personal information to third-party service providers when it is necessary. These third-party service providers have experienced data breaches and other attacks that included unauthorized access to Confidential Information in the past, including a breach of the networks of one of our credit decisioning providers in September 2015, during which a subset of records containing current and potential customer information was acquired by an external party.

Our procedures and safeguards to prevent unauthorized access to sensitive data and to defend against attacks seeking to disrupt our services must be continually evaluated and revised to address the ever-evolving threat landscape. We cannot make assurances that all preventive actions taken will adequately repel a significant attack or prevent information security breaches or the misuses of data, unauthorized access by third parties or employees, or exploits against third-party supplier environments. If we or our third-party suppliers are subject to such attacks or security breaches, we may incur significant costs or other material financial impact, be subject to regulatory investigations, sanctions and private litigation, experience disruptions to our operations or suffer damage to our reputation. Any future cyber-attacks, data breaches, or security incidents may have a materially adverse effect on our business, financial condition, and operating results.

Changes in regulations or in the regulatory framework under which we operate could adversely affect our business, financial condition and operating results.

The FCC regulates the licensing, construction, modification, operation, ownership, sale, and interconnection of wireless communications systems, as do some state and local regulatory agencies. In particular, the FCC imposes significant regulation on licensees of wireless spectrum with respect to how radio spectrum is used by licensees, the nature of the services that licensees may offer and how the services may be offered, and the resolution of issues of interference between spectrum bands. Additionally, the Federal Trade Commission and other federal and state agencies have asserted that they have jurisdiction over some consumer protection, and elimination and prevention of anticompetitive business practices with respect to the provision of wireless products and services. We are subject to regulatory oversight by various federal, state and local agencies, as well as judicial review and actions, on issues related to the wireless industry that include, but are not limited to: roaming, interconnection, spectrum allocation and licensing, facilities siting, pole attachments, intercarrier compensation, Universal Service Fund (“USF”), net neutrality, 911 services, consumer protection, consumer privacy, and cybersecurity. We are also subject to regulations in connection with other aspects of our business, including handset financing and insurance activities.

We cannot assure you that the FCC or any other federal, state or local agencies will not adopt regulations or take enforcement or other actions that would adversely affect our business, impose new costs, or require changes in current or planned operations. For example, under the Obama administration, the FCC established new net neutrality and privacy regimes that applied to our operations. Both sets of rules potentially subjected some of our initiatives and practices to more burdensome requirements and heightened scrutiny by federal and state regulators, the public, edge providers, and private litigants regarding whether such initiatives or practices are compliant. While the FCC rules are now largely rolled back under the Trump administration, some state legislators and regulators are seeking to replace them with state laws, perpetuating uncertainty regarding the regulatory environment around these issues.

In addition, states are increasingly focused on the quality of service and support that wireless communication providers provide to their customers and several states have proposed or enacted new and potentially burdensome regulations in this area. We also face potential investigations by, and inquiries from or actions by state Public Utility Commissions. We also cannot assure you that Congress will not amend the Communications Act, from which the FCC obtains its authority and which serves to limit state authority, or enact other legislation in a manner that could be adverse to our business. Additionally, California passed the California Consumer Privacy Act (the “CCPA”) in June 2018, putting into place new data privacy rights for consumers, effective in January 2020. Legislators have stated that they intend to propose amendments to the CCPA before it goes into effect, and it remains unclear what, if any, modifications will be made to this legislation or how it will be interpreted. We will likely have to incur significant implementation costs to ensure compliance with the CCPA, and we could see increased litigation costs once the law goes into effect. If we are unable to put proper controls and procedures in place to ensure compliance, it could have an adverse effect on our business. Other states are considering similar legislation, which, if passed, could create more risks and potential costs for us.

Failure to comply with applicable regulations could have a material adverse effect on our business, financial condition and operating results. We could be subject to fines, forfeitures, and other penalties (including, in extreme cases, revocation of our spectrum licenses) for failure to comply with FCC or other governmental regulations, even if any such non-compliance was

unintentional. The loss of any licenses, or any related fines or forfeitures, could adversely affect our business, financial condition, and operating results.
