Notes to Unaudited Consolidated Financial Statements

At and for the Three Months Ended March 31, 2017 and 2016

(1) Basis of Presentation

Overview

Brookline Bancorp, Inc. (the "Company") is a bank holding company (within the meaning of the Bank Holding Company Act of 1956, as amended) and the parent of Brookline Bank, a Massachusetts-chartered savings bank; Bank Rhode Island ("BankRI"), a Rhode Island-chartered financial institution; and First Ipswich Bank ("First Ipswich"), a Massachusetts-chartered trust company (collectively referred to as the "Banks"). The Banks are all members of the Federal Reserve System. The Company is also the parent of Brookline Securities Corp. ("BSC"). The Company's primary business is to provide commercial, business and retail banking services to its corporate, municipal and retail customers through the Banks and its non-bank subsidiaries.

Brookline Bank, which includes its wholly-owned subsidiaries BBS Investment Corp., Longwood Securities Corp. and its 84.2%-owned subsidiary, Eastern Funding LLC ("Eastern Funding"), operates 25 full-service banking offices in the greater Boston metropolitan area. BankRI, which includes its wholly-owned subsidiaries, Acorn Insurance Agency, BRI Realty Corp., Macrolease Corporation ("Macrolease"), BRI Investment Corp. and its wholly-owned subsidiary, BRI MSC Corp., operates 20 full-service banking offices in the greater Providence area. First Ipswich, which includes its wholly-owned subsidiaries, First Ipswich Insurance Agency and First Ipswich Securities II Corp., operates six full-service banking offices on the north shore of eastern Massachusetts.

The Company's activities include acceptance of commercial, municipal and retail deposits, origination of mortgage loans on commercial and residential real estate located principally in Massachusetts and Rhode Island, origination of commercial loans and leases to small- and mid-sized businesses, investment in debt and equity securities, and the offering of cash management and investment advisory services. The Company also provides specialty equipment financing through its subsidiaries Eastern Funding, which is based in New York City, New York, and Macrolease, which is based in Plainview, New York.

The Company and the Banks are supervised, examined and regulated by the Board of Governors of the Federal Reserve System ("FRB"). As Massachusetts-chartered savings bank and trust companies, Brookline Bank and First Ipswich, respectively, are also subject to regulation under the laws of the Commonwealth of Massachusetts and the jurisdiction of the Massachusetts Division of Banks. As a Rhode Island-chartered financial institution, BankRI is subject to regulation under the laws of the State of Rhode Island and the jurisdiction of the Banking Division of the Rhode Island Department of Business Regulation.

The Federal Deposit Insurance Corporation ("FDIC") offers insurance coverage on all deposits up to $250,000 per depositor at each of the Banks. As FDIC-insured depository institutions, the Banks are also secondarily subject to supervision, examination and regulation by the FDIC. Additionally, as a Massachusetts-chartered savings bank, Brookline Bank is also insured by the Depositors Insurance Fund ("DIF"), a private industry-sponsored insurance company. The DIF insures savings bank deposits in excess of the FDIC insurance limits. As such, Brookline Bank offers 100% insurance on all deposits as a result of a combination of insurance from the FDIC and the DIF. Brookline Bank is required to file reports with the DIF.

Basis of Financial Statement Presentation

The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”). In the opinion of Management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.

Notes to Unaudited Consolidated Financial Statements (Continued)

At and for the Three Months Ended March 31, 2017 and 2016

In preparing these consolidated financial statements, Management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to significant change in the near-term include the determination of the allowance for loan and lease losses, the determination of fair market values of assets and liabilities, including acquired loans and leases, the review of goodwill and intangibles for impairment and the review of deferred tax assets for valuation allowances.

The judgments used by Management in applying these critical accounting policies may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.

Reclassification

Certain previously reported amounts have been reclassified to conform to the current year's presentation.

(2) Recent Accounting Pronouncements

In March 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2017-08, Premium Amortization on Purchased Callable debt Securities (Subtopic 310-20). This ASU was issued to clarify the Subtopic 310-20, and to amend the amortization period for certain purchased callable debt securities held at a premium. For public entities, this ASU is effective for annual reporting periods beginning after December 15, 2018. The Company adopted ASU 2017-08 effective January 1, 2017 and the adoption did not have a material impact on the Company’s consolidated financial statements.

In March 2017, the FASB issued Accounting Standards Update ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (Topic 715). This ASU was issued primarily to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. This ASU is effective for annual reporting periods beginning after December 15, 2017. Management has determined that ASU 2017-07 does apply, but has not determined the impact, if any, as of March 31, 2017. Management will meet to discuss and will put together a project team to assess steps to adoption prior to implementation of the standard in 2018.

In February 2017, the FASB issued ASU 2017-05, Other Income Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20). This ASU was issued to clarify the scope of Subtopic 610-20, and to add guidance for partial sales of nonfinancial assets. For public entities, this ASU is effective for annual reporting periods beginning after December 15, 2017. Management believes that this ASU applies and is assessing the impact, if any, as of March 31, 2017. Management will form a project team to determine the impact and if the Company will early adopt the ASU.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). This ASU was issued to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. For public entities, this ASU is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted and application should be on a prospective basis. Management has evaluated this ASU and believes that ASU 2017-04 does apply. Management will form a project team to determine the impact and if the Company will early adopt the ASU.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). This ASU was issued to provide clarification and uniformity on the presentation and classification of certain cash receipts and cash payments in the statement of cash flows under Topic 230. This amendments presented in this ASU are effective for fiscal years beginning after December 15, 2017. As of March 31, 2017, management believes that ASU 2016-15 does apply, and after completing an internal analysis has determined the impact of adoption of this ASU in 2018 will be related to financial statement presentation.

In June 2016, the FASB issued ASU 2016-13, Financial instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The intent of this ASU is to replace the current GAAP method of calculating credit losses. Current GAAP uses a higher threshold at which likely losses can be calculated and recorded. The new process will require institutions to account for likely losses that originally would not have been part of the calculation. The calculation will

incorporate future forecasting in addition to historical and current measures. For public entities that file with the SEC, this ASU is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. This ASU must be applied prospectively to debt securities marked as other than temporarily impaired. A retrospective approach will be applied cumulatively to retained earnings. Early adoption is permitted as of the fiscal years beginning after December 15, 2018. Management has determined that ASU 2016-13 does apply, but has not determined the impact, if any, as of March 31, 2017. In preparation for the adoption in 2019 of this ASU, management formed a steering committee which has developed an approach for implementation which includes the selection of a third party software service provider.

In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. The intention of this ASU is to provide additional clarification on specific issues brought forth by the FASB and the International Accounting Standards Board Joint Transition Resource Group for Revenue Recognition in relation to Topic 606 and revenue recognition. This ASU is to have the same effective date as ASU 2015-14 which deferred the effective date of ASU 2014-09 to December 15, 2017. Management has determined that ASU 2016-12 does apply, but has not determined the impact, if any, as of March 31, 2017. Management assembled a project team to address the changes pursuant to Topic 606. The project team has made an initial scope assessment and additional progress over the topic is expected to be made in the second quarter of 2017.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU was issued as part of the FASB Simplification Initiative which intends to reduce the complexity of GAAP while improving usefulness to users. The ASU was effective for annual periods beginning after December 15, 2016, and interim periods within those annual reporting periods with early adoption available. The Company adopted ASU 2016-09 effective January 1, 2017 and the adoption did not have a material impact on the Company’s consolidated financial statements.

The requirement to report the excess tax benefit related to settlements of share-based payment awards in earnings as an increase to or reduction in provision for income taxes has been applied to settlements occurring on or after January 1, 2017. Previously, such amounts were recorded in the pool of excess tax benefits included in additional paid-in capital, if such pool was available. Excess tax benefits are no longer recognized in additional paid-in capital and as a result, the assumed proceeds from applying the treasury stock method when computing earnings per share should exclude the amount of excess tax benefits that would have previously been recognized in additional paid-in capital. Additionally, consistent with this change, excess tax benefits are now classified along with other income tax cash flows as an operating activity rather than a financing activity in the statement of cash flows. ASU 2016-09 also amended the classification and statutory tax withholding requirements in order to qualify as an equity awards and the classification on the statement of cash flows for employee taxes paid when the Company withholds shares, and as a result, will be presented as a financing activity on the statement of cash flows. The Company did not have any settlements of share-based payment awards for the three months ended March 31, 2017, therefore there was no impact in applying this guidance.

ASU 2016-09 also provided that an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. The Company chose a modified retrospective approach and a policy election to account for forfeitures when they occur. This change resulted in a cumulative adjustment that is immaterial to all periods presented.

In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This ASU was issued to clarify how to recognize revenue depending on an entities position, in relation to another entity involved, on contracts with customers. The entity can either be a principal party or an agent, and must record revenue accordingly. This ASU is not yet effective. Since this ASU affects ASU 2014-09, and that effective date was deferred, this ASU remains suspended too. Management believes that this ASU applies and is assessing the impact, if any, as of March 31, 2017. Management assembled a project team to address the changes pursuant to Topic 606. The project team has made an initial scope assessment and additional progress over the topic is expected to be made in the second quarter of 2017.

In February 2016, FASB issued ASU 2016-02, Leases. This ASU requires lessees to put most leases on their balance sheet but recognize expenses on their income statements in a manner similar to current accounting. This ASU also eliminates current real estate-specific provisions for all companies. For lessors, this ASU modifies the classification criteria and the accounting for sales-type and direct financing leases. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods therein. Early adoption is permitted. Management believes that this ASU applies and is assessing the

impact, if any, as of March 31, 2017. Management has met to discuss the impact and will assemble a project team to assess steps required for adoption prior to implementation of the standard in 2019.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments. This ASU significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial instruments. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods therein. Management believes that this ASU applies and is assessing the impact, if any, as of March 31, 2017. Management has put together a steering committee which has made progress identifying the additional data requirements necessary to implement the ASU and has determined an approach for implementation which includes the selection of a third party software service provider.

In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. This ASU was issued to defer the effective date of ASU 2014-09 for all entities by one year. In effect, public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods (including interim reporting periods within those period) beginning after December 15, 2017. Management believes that this ASU applies and is assessing the impact, if any, as of March 31, 2017. Management assembled a project team to address the changes pursuant to Topic 606. The project team has made an initial scope assessment and additional progress over the topic is expected to be made in the second quarter of 2017.

The Company performs regular analysis on the investment securities available-for-sale portfolio to determine whether a decline in fair value indicates that an investment security is OTTI. In making these OTTI determinations, management considers, among other factors, the length of time and extent to which the fair value has been less than amortized cost; projected future cash flows; credit subordination and the creditworthiness; capital adequacy and near-term prospects of the issuers.

Management also considers the Company's capital adequacy, interest-rate risk, liquidity and business plans in assessing whether it is more likely than not that the Company will sell or be required to sell the investment securities before recovery. If the Company determines that a decline in fair value is OTTI and that it is more likely than not that the Company will not sell or be required to sell the investment security before recovery of its amortized cost, the credit portion of the impairment loss is recognized in the Company's unaudited consolidated statement of income and the noncredit portion is recognized in accumulated other comprehensive income. The credit portion of the OTTI impairment represents the difference between the amortized cost and the present value of the expected future cash flows of the investment security. If the Company determines that a decline in fair value is OTTI and it is more likely than not that it will sell or be required to sell the investment security before recovery of its amortized cost, the entire difference between the amortized cost and the fair value of the security will be recognized in the Company's unaudited consolidated statement of income.

Investment Securities Available-For-Sale Impairment Analysis

The following discussion summarizes, by investment security type, the basis for evaluating if the applicable investment securities within the Company’s available-for-sale portfolio were OTTI as of March 31, 2017. Based on the analysis below and the determination that, it is more likely than not that the Company will not sell or be required to sell the investment securities before recovery of its amortized cost. The Company's ability and intent to hold these investment securities until recovery is supported by the Company's strong capital and liquidity positions as well as its historically low portfolio turnover. As such, management has determined that the investment securities are not OTTI as of March 31, 2017. If market conditions for

investment securities worsen or the creditworthiness of the underlying issuers deteriorates, it is possible that the Company may recognize additional OTTI in future periods.

U.S. Government-Sponsored Enterprises

The Company invests in securities issued by U.S. Government-sponsored enterprises ("GSEs"), including GSE debentures, mortgage-backed securities ("MBSs"), and collateralized mortgage obligations ("CMOs"). GSE securities include obligations issued by the Federal National Mortgage Association ("FNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC"), the Government National Mortgage Association ("GNMA"), the Federal Home Loan Banks ("FHLB") and the Federal Farm Credit Bank. As of March 31, 2017, only GNMA MBSs and CMOs, and Small Business Administration ("SBA") commercial loan asset-backed securities in our available-for-sale portfolio with an estimated fair value of $27.2 million were backed explicitly by the full faith and credit of the U.S. Government, compared to $26.2 million as of December 31, 2016.

As of March 31, 2017, the Company owned thirty-seven GSE debentures with a total fair value of $121.1 million, and a net unrealized loss of $0.7 million. As of December 31, 2016, the Company held twenty-nine GSE debentures with a total fair value of $97.0 million, and a net unrealized loss of $1.1 million. As of March 31, 2017, twenty-two of the thirty-seven securities in this portfolio were in an unrealized loss position. As of December 31, 2016, twenty-one of the twenty-nine securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA/SBA) guarantee of the U.S Government. During the three months ended March 31, 2017, the Company purchased a total of $23.9 million GSE debentures. This compares to $21.5 million purchased during the same period in 2016.

As of March 31, 2017, the Company owned 62 GSE CMOs with a total fair value of $149.7 million and a net unrealized loss of $3.4 million. As of December 31, 2016, the Company held 62 GSE CMOs with a total fair value of $158.0 million with a net unrealized loss of $3.4 million. As of March 31, 2017, 47 of the 62 securities in this portfolio were in an unrealized loss position. As of December 31, 2016, 47 of the 62 securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA) guarantee of the U.S Government. During the three months ended March 31, 2017 and 2016, the Company did not purchase any GSE CMOs.

As of March 31, 2017, the Company owned 192 GSE MBSs with a total fair value of $201.9 million and a net unrealized loss of $1.7 million. As of December 31, 2016, the Company held 195 GSE MBSs with a total fair value of $212.9 million with a net unrealized loss of $2.0 million. As of March 31, 2017, 67 of the 192 securities in this portfolio were in an unrealized loss position. As of December 31, 2016, 60 of the 195 securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA) guarantee of the U.S Government. During the three months ended March 31, 2017, the Company did not purchase any GSE MBSs, as compared to the same period in 2016, when the Company purchased a total of $20.5 million of GSE MBSs.

SBA Commercial Loan Asset-Backed

As of March 31, 2017 and December 31, 2016, the Company owned SBA securities with a total fair value of $0.1 million and $0.1 million, respectively, which approximated amortized cost. As of March 31, 2017, four of the six securities in this portfolio were in an unrealized loss position. As of December 31, 2016, four of the six securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the explicit (SBA) guarantee of the U.S Government.

Corporate Obligations

From time to time, the Company may invest in high-quality corporate obligations to provide portfolio diversification and improve the overall yield on the portfolio. The Company owned sixteen corporate obligation securities with a total fair value of $48.5 million and a net unrealized gain of $0.2 million as of March 31, 2017. This compares to sixteen corporate obligation securities with a total fair value of $48.5 million and a net unrealized gain of $0.2 million as of December 31, 2016. As of March 31, 2017, two of the sixteen securities in this portfolio were in an unrealized loss position. As of December 31, 2016, three of the sixteen securities in this portfolio was in an unrealized loss position. Full collection of the obligations is expected because the financial condition of the issuers is sound, they have not defaulted on scheduled payments, the obligations are rated investment grade, and the Company has the ability and intent to hold the obligations for a period of time to recover the amortized cost. During the three months ended March 31, 2017 and 2016, the Company did not purchase any corporate obligations.

Accretable Yield for the Acquired Loan Portfolio

The following table summarizes activity in the accretable yield for the acquired loan portfolio for the periods indicated:



	Three Months Ended March 31,
	2017			2016

Reclassification from (to) nonaccretable difference as a result of changes in expected cash flows	126			188
Balance at end of period	$	13,072		$	19,800

On a quarterly basis, subsequent to acquisition, management reforecasts the expected cash flows for acquired ASC 310-30 loans, taking into account prepayment speeds, probability of default and loss given defaults. Management compares cash flow projections per the reforecast to the original cash flow projections and determines whether any reduction in cash flow expectations are due to deterioration, or if the change in cash flow expectation is related to noncredit events. This cash flow analysis is used to evaluate the need for a provision for loan and lease losses and/or prospective yield adjustments. During the three months ended March 31, 2017 and 2016, accretable yield adjustments totaling $0.1 million and $0.2 million, respectively, were made for certain loan pools. These accretable yield adjustments, which are subject to continued re-assessment, will be recognized over the remaining lives of those pools.

Allowance for Loan and Lease Losses Methodology

Management has established a methodology to determine the adequacy of the allowance for loan and lease losses that assesses the risks and losses inherent in the loan and lease portfolio. Additions to the allowance for loan and lease losses are made by charges to the provision for credit losses. Losses on loans and leases are charged off against the allowance when all or a portion of a loan or lease is considered uncollectible. Subsequent recoveries on loans previously charged off, if any, are credited to the allowance when realized.

Management uses a consistent and systematic process and methodology to evaluate the adequacy of the allowance for loan and lease losses on a quarterly basis. For purposes of determining the allowance for loan and lease losses, the Company has segmented certain loans and leases in the portfolio by product type into the following segments: (1) commercial real estate loans, (2) commercial loans and leases, and (3) consumer loans. Portfolio segments are further disaggregated into classes based on the associated risks within the segments. Commercial real estate loans are divided into three classes: commercial real estate loans, multi-family mortgage loans, and construction loans. Commercial loans and leases are divided into three classes: commercial loans which includes taxi medallion loans, equipment financing, and loans to condominium associations. Consumer loans are divided into three classes: residential mortgage loans, home equity loans, and other consumer loans. A formula-based credit evaluation approach is applied to each group, coupled with an analysis of certain loans for impairment. For each class of loan, management makes significant judgments in selecting the estimation method that fits the credit characteristics of its class and portfolio segment as set forth below.

The general allowance related to loans collectively evaluated for impairment is determined using a formula-based approach utilizing the risk ratings of individual credits and loss factors derived from historic portfolio loss rates, which include estimates of incurred losses over an estimated loss emergence period (“LEP”). The LEP was generated utilizing a charge-off look-back analysis which studied the time from the first indication of elevated risk of repayment (or other early event indicating a problem) to eventual charge-off to support the LEP considered in the allowance calculation. This reserving methodology established the approximate number of months of LEP that represents incurred losses for each portfolio. In addition to quantitative measures, relevant qualitative factors include, but are not limited to: (1) levels and trends in past due and impaired loans, (2) levels and trends in charge-offs, (3) changes in underwriting standards, policy exceptions, and credit policy, (4) experience of lending management and staff, (5) economic trends, (6) industry conditions, (7) effects of changes in credit concentrations, (8) interest rate environment, and (9) regulatory and other changes. The general allowance related to the acquired loans collectively evaluated for impairment is determined based upon the degree, if any, of deterioration in the pooled loans subsequent to acquisition. The qualitative factors used in the determination are the same as those used for originated loans.

Specific valuation allowances are established for impaired originated loans with book values greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent impaired loans, for any excess of a loan's book balance and the fair value of its underlying collateral. Specific valuation allowances are established for acquired loans with deterioration in the discounted present value of expected future cash flows since acquisitions or, in the case of collateral dependent impaired loans, for any increase in the excess of a loan's book balance greater than the fair value of its underlying

collateral. A specific valuation allowance for losses on troubled debt restructured ("TDR") loans is determined by comparing the net carrying amount of the troubled debt restructured loan with the restructured loan's cash flows discounted at the original effective rate. Impaired loans are reviewed quarterly with adjustments made to the calculated reserve as necessary.

As of March 31, 2017, management believes that the methodology for calculating the allowance is sound and that the allowance provides a reasonable basis for determining and reporting on probable losses in the Company’s loan portfolios.

As of March 31, 2017, the Company had a portfolio of approximately $30.6 million in loans secured by taxi medallions issued by the cities of Boston and Cambridge. As of December 31, 2016, this portfolio was approximately $31.1 million. Application-based mobile ride services, such as Uber and Lyft, have generated increased competition in the transportation sector, resulting in a reduction in taxi utilization and, as a result, a reduction in the collateral value and credit quality of taxi medallion loans. This has increased the likelihood that loans secured by taxi medallions may default, or that the borrowers may be unable to repay these loans at maturity, potentially resulting in an increase in past due loans, troubled debt restructurings, and charge-offs. The Company’s allowance calculation included a further segmentation of the commercial loans and leases to reflect the increased risk in the Company’s taxi medallion portfolio. This allowance calculation segmentation represents management’s estimations of the current risks associated with the portfolio.

As of March 31, 2017, the Company had an allowance for loan and lease losses associated with taxi medallion loans of

$7.6 million of which $5.5 million were specific reserves and $2.1 million was a general reserve. As of December 31, 2016, the Company had an allowance for loan and lease losses associated with taxi medallion loans of $1.3 million of which $0.1 million were specific reserves and $1.2 million was a general reserve. The increase in the allowance for loan and leases associated with taxi medallion loans was primarily driven by the increase in specific reserves due to changes in the underlying collateral value of taxi medallions and the increase in general reserve due to the increase in the historical loss factor applied to the taxi medallion loans. The total troubled debt restructured loans and leases secured by taxi medallions increased by $0.7 million from $6.1 million at December 31, 2016 to $6.8 million at March 31, 2017 due to two taxi medallion relationships which were restructured during the quarter. The total loans and leases secured by taxi medallions that were placed on nonaccrual increased to $14.2 million at March 31, 2017 from $13.4 million at December 31, 2016 due to the two restructured taxi medallion relationships mentioned above which were placed on nonaccrual status in the quarter. In addition, further declines in demand for taxi services or further deterioration in the value of taxi medallions may result in higher delinquencies and losses beyond that provided for in the allowance for loan and lease losses.

The general allowance for loan and lease losses was $56.0 million as of March 31, 2017, compared to $53.5 million as of December 31, 2016. The general portion of the allowance for loan and lease losses increased by $2.5 million during the three months ended March 31, 2017, as a result of the continued growth in the Company's loan portfolios and the increase in historical loss factors applied to commercial real estate and commercial portfolios, offset by the decrease in historical loss factors applied to the consumer loan portfolios.

The specific allowance for loan and lease losses was $10.1 million as of March 31, 2017, compared to $0.2 million as of December 31, 2016. The specific allowance increased by $9.9 million during the three months ended March 31, 2017, primarily due to the reduction in collateral values for taxi medallion loans and the increase in specific reserves for two commercial loans during the quarter.

Credit Quality Assessment

At the time of loan origination, a rating is assigned based on the capacity to pay and general financial strength of the borrower, the value of assets pledged as collateral, and the evaluation of third party support such as a guarantor. The Company continually monitors the quality of the loan portfolio using all available information. The officer responsible for handling each loan is required to initiate changes to risk ratings when changes in facts and circumstances occur that warrant an upgrade or downgrade in a loan rating. Based on this information, loans demonstrating certain payment issues or other weaknesses may be categorized as delinquent, impaired, nonperforming and/or put on nonaccrual status. Additionally, in the course of resolving such loans, the Company may choose to restructure the contractual terms of certain loans to match the borrower's ability to repay the loan based on their current financial condition. If a restructured loan meets certain criteria, it may be categorized as a troubled debt restructuring.

The Company reviews numerous credit quality indicators when assessing the risk in its loan portfolio. For all loans, the Company utilizes an eight-grade loan rating system, which assigns a risk rating to each borrower based on a number of quantitative and qualitative factors associated with a loan transaction. Factors considered include industry and market conditions; position within the industry; earnings trends; operating cash flow; asset/liability values; debt capacity; guarantor strength; management and controls; financial reporting; collateral; and other considerations. In addition, the Company's independent loan review group evaluates the credit quality and related risk ratings in all loan portfolios. The results of these reviews are reported to the Risk Committee of the Board of Directors on a periodic basis and annually to the Board of Directors. For the consumer loans, the Company heavily relies on payment status for calibrating credit risk.

The ratings categories used for assessing credit risk in the commercial real estate, multi-family mortgage, construction, commercial, equipment financing, condominium association and other consumer loan and lease classes are defined as follows:

1 -4 Rating—Pass

Loan rating grades "1" through "4" are classified as "Pass," which indicates borrowers are performing in accordance with the terms of the loan and are less likely to result in loss due to the capacity of the borrower to pay and the adequacy of the value of assets pledged as collateral.

5 Rating—Other Assets Especially Mentioned ("OAEM")

Borrowers exhibit potential credit weaknesses or downward trends deserving management's attention. If not checked or corrected, these trends will weaken the Company's asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned.

6 Rating—Substandard

Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt. Substandard loans may be inadequately protected by the current net worth and paying capacity of the obligors or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy. Although no loss of principal is envisioned, there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Collateral coverage may be inadequate to cover the principal obligation.

7 Rating—Doubtful

Borrowers exhibit well-defined weaknesses that jeopardize the orderly liquidation of debt with the added provision that the weaknesses make collection of the debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely.

8 Rating—Definite Loss

Borrowers deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuation as active assets of the Company is not warranted.

Assets rated as "OAEM," "substandard" or "doubtful" based on criteria established under banking regulations are collectively referred to as "criticized" assets.

At and for the Three Months Ended March 31, 2017 and 2016

Commercial Real Estate Loans—As of March 31, 2017, loans outstanding in the three classes within this segment expressed as a percentage of total loans and leases outstanding were as follows: commercial real estate loans -- 37.8%; multi-family mortgage loans -- 13.4%; and construction loans -- 2.8%.

Loans in this portfolio that are on nonaccrual status and/or risk-rated "substandard" or worse are evaluated on an individual loan basis for impairment. For non-impaired commercial real estate loans, loss factors are applied to outstanding loans by risk rating for each of the three classes in the portfolio. The factors applied are based primarily on historic loan loss experience and an assessment of internal and external factors and other relevant information.

Commercial Loans and Leases—As of March 31, 2017, loans and leases outstanding in the three classes within this segment expressed as a percent of total loans and leases outstanding were as follows: commercial loans and leases -- 11.8%; equipment financing loans -- 14.9%; and loans to condominium associations -- 1.1%.

Loans and leases in this portfolio that are on nonaccrual status and/or risk-rated "substandard" or worse are evaluated on an individual basis for impairment. For non-impaired commercial loans and leases, loss factors are applied to outstanding loans by risk rating for each of the three classes in the portfolio.

Consumer Loans—As of March 31, 2017, loans outstanding within the three classes within this segment expressed as a percent of total loans and leases outstanding were as follows: residential mortgage loans -- 11.6%, home equity loans -- 6.3%, and other consumer loans -- 0.3%.

Significant risk characteristics related to the residential mortgage and home equity loan portfolios are the geographic concentration of the properties financed within selected communities in the greater Boston and Providence metropolitan areas. The payment status and loan-to-value ratio are the primary credit quality indicator used for residential mortgage loans and home equity loans. Generally, loans are not made when the loan-to-value ratio exceeds 80% unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Consumer loans that become 90 days or more past due, or are placed on nonaccrual regardless of past due status, are reviewed on an individual basis for impairment by assessing the net realizable value of underlying collateral and the economic condition of the borrower.

Impaired Loans and Leases

A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. The Company has defined the population of impaired loans to include nonaccrual loans and troubled debt restructured loans.

When the ultimate collectability of the total principal of an impaired loan or lease is in doubt and the loan is on nonaccrual status, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan or lease is not in doubt and the loan or lease is on nonaccrual status, contractual interest is credited to interest income when received, under the cash basis method.

The following tables include the recorded investment and unpaid principal balances of impaired loans and leases with the related allowance amount, if applicable, for the originated and acquired loan and lease portfolios at the dates indicated. Also presented are the average recorded investments in the impaired loans and leases and the related amount of interest recognized during the period that the impaired loans were impaired.

Troubled Debt Restructured Loans and Leases

A specific valuation allowance for losses on troubled debt restructured loans is determined by comparing the net carrying amount of the troubled debt restructured loan with the restructured loan's cash flows discounted at the original effective rate.

The following table sets forth information regarding troubled debt restructured loans and leases at the dates indicated:



	At March 31, 2017		At December 31, 2016
	(In Thousands)
Troubled debt restructurings:
On accrual	$	13,662	$	13,883
On nonaccrual	11,756		11,919
Total troubled debt restructurings	$	25,418	$	25,802

Total troubled debt restructuring loans and leases decreased by $0.4 million to $25.4 million at March 31, 2017 from

$25.8 million at December 31, 2016, primarily driven by the restructuring of two taxi medallion loans and one commercial loan, offset by the repayment of other troubled debt restructured loans.

The recorded investment in troubled debt restructurings and the associated specific allowances for loan and lease losses, in the originated and acquired loan and lease portfolios, that were modified during the periods indicated, are as follows.

At and for the Three Months Ended March 31, 2017 and 2016

The following table sets forth the Company's end-of-period balances for troubled debt restructurings that were modified during the periods indicated, by type of modification.



	Three Months Ended March 31,
	2017		2016
	(In Thousands)
Loans with one modification:
Adjusted principal	$	375	$	—
Interest only	—		2,412
Combination maturity, principal, interest rate	390		6,363
Total loans with one modification	$	765	$	8,775

The troubled debt restructuring loans and leases that were modified for the three months ended March 31, 2017 and 2016 were $0.8 million and $8.8 million, respectively. The decrease in troubled debt restructuring loans and leases that were modified for the three months ended March 31, 2017 was primarily due to the decrease in the modification of loans and leases secured by taxi medallions.

There were no troubled debt restructuring loans and leases with more than one modification during the three months ended March 31, 2017 and 2016.

The net recoveries of the performing and nonperforming troubled debt restructuring loans and leases for the three months ended March 31, 2017 were $7 thousand. There were no charge-offs or recoveries for the performing and nonperforming troubled debt restructuring loans and leases for the three months ended March 31, 2016.

As of March 31, 2017 and 2016, there were no commitments to lend funds to debtors owing receivables whose terms had been modified in troubled debt restructurings.

(6) Goodwill and Other Intangible Assets

The following table sets forth the carrying value of goodwill and other intangible assets at the dates indicated:



	At March 31, 2017		At December 31, 2016
	(In Thousands)
Goodwill	$	137,890	$	137,890
Other intangible assets:
Core deposits	6,512		7,044
Trade name	1,089		1,089
Total other intangible assets	7,601		8,133
Total goodwill and other intangible assets	$	145,491	$	146,023

At December 31, 2013, the Company concluded that the BankRI name would continue to be utilized in its marketing strategies; therefore, the trade name with carrying value of $1.1 million, has an indefinite life and ceased to amortize.

The weighted-average amortization period for the core deposit intangible is 8.6 years.

(7) Accumulated Other Comprehensive Income (Loss)

For the three months ended March 31, 2017 and March 31, 2016, the Company’s accumulated other comprehensive income (loss) includes the following two components: (i) unrealized holding gains (losses) on investment securities available-for-sale; and (ii) adjustment of accumulated obligation for postretirement benefits.

Changes in accumulated other comprehensive income (loss) by component, net of tax, were as follows for the periods indicated:



	Three Months Ended March 31, 2017
	Investment Securities Available-for-Sale			Postretirement Benefits		Accumulated Other Comprehensive Loss
	(In Thousands)
Balance at December 31, 2016	$	(4,213	)	$	395	$	(3,818	)
Other comprehensive income	557			—		557
Balance at March 31, 2017	$	(3,656	)	$	395	$	(3,261	)



	Three Months Ended March 31, 2016
	Investment Securities Available-for-Sale			Postretirement Benefits		Accumulated Other Comprehensive Loss
	(In Thousands)
Balance at December 31, 2015	$	(2,827	)	$	351	$	(2,476	)
Other comprehensive income	5,828			—		5,828
Balance at March 31, 2016	$	3,001		$	351	$	3,352

The Company did not reclassify any amounts out of accumulated other comprehensive income (loss) for the three months ended March 31, 2017 and March 31, 2016.

(8) Derivatives and Hedging Activities

The Company utilizes loan level derivatives which consist of interest-rate contracts (swaps, caps and floors), and risk participation agreements as part of the Company's interest-rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company's intended use for the loan level derivatives at inception, the Company designates the derivative as either an economic hedge of an asset or liability, or a hedging instrument subject to the hedge accounting provisions of FASB ASC Topic 815, "Derivatives and Hedging".

Table of Contents

BROOKLINE BANCORP, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements (Continued)

At and for the Three Months Ended March 31, 2017 and 2016

Interest-rate swap, cap and floor agreements are entered into as hedges against future interest-rate fluctuations on specifically identified assets or liabilities. The Company did not have derivative fair value hedges or derivative cash flow hedges as of March 31, 2017 or December 31, 2016.

Derivatives not designated as hedges are not speculative but rather, result from a service the Company provides to certain customers for a fee. The Company executes loan level derivative products such as interest-rate swap agreements with commercial banking customers to aid them in managing their interest-rate risk. The interest-rate swap contracts allow the commercial banking customers to convert floating-rate loan payments to fixed-rate loan payments. The Company concurrently enters into offsetting swaps with a third party financial institution, effectively minimizing its net risk exposure resulting from such transactions. The third-party financial institution exchanges the customer's fixed-rate loan payments for floating-rate loan payments. As the interest-rate swap agreements associated with this program do not meet hedge accounting requirements, changes in the fair value are recognized directly in earnings.

The Company utilizes risk participation agreements with other banks participating in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. Risk participation agreements are derivative financial instruments and are recorded at fair value. These derivatives are not designated as hedges and therefore, changes in fair value are recorded directly through earnings at each reporting period.

Under a risk participation-out agreement, a derivative asset, the Corporation participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower, for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Corporation assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower, for a fee received from the other bank. The Company had no risk participation-in agreements in 2016.

The Company offers foreign exchange contracts to commercial borrowers to accommodate their business needs. These foreign exchange contracts do not qualify as hedges for accounting purposes. To mitigate the market and liquidity risk associated with these foreign exchange contracts, the Company enters into similar offsetting positions.

Asset derivatives and liability derivatives are included in other assets and accrued expenses and other liabilities on the unaudited consolidated balance sheets.

The following tables presents the Company's customer related derivative positions for the periods indicated below for those derivatives not designated as hedging.

Certain derivative agreements contain provisions that require the Company to post collateral if the derivative exposure exceeds a threshold amount. The Company posted collateral of $29.9 million and $34.5 million in the normal course of business as of March 31, 2017 and December 31, 2016, respectively.

The Company has agreements with certain of its derivative counterparties that contain credit-risk-related contingent provisions. These provisions provide the counterparty with the right to terminate its derivative positions and require the Company to settle its obligations under the agreements if the Company defaults on certain of its indebtedness or if the Company fails to maintain its status as a well-capitalized institution.

(9) Stock Based Compensation

As of March 31, 2017, the Company had three active recognition and retention plans: the 2003 Recognition and Retention Plan (the "2003 RRP") with 1,250,000 authorized shares, the 2011 Restricted Stock Award Plan ("2011 RSA") with 500,000 authorized shares and the 2014 Equity Incentive Plan ("2014 Plan") with 1,750,000 authorized shares. The 2003 RRP, the 2011 RSA and the 2014 Plan are collectively referred to as the "Plans". The purpose of the Plans is to promote the long-term financial success of the Company and its subsidiaries by providing a means to attract, retain and reward individuals who contribute to such success and to further align their interests with those of the Company's stockholders.

Of the awarded shares, generally 50% vest ratably over three years with one-third of such shares vesting at each of the first, second and third anniversary dates of the awards. These are referred to as "time-based shares". The remaining 50% of each award has a cliff vesting schedule and will vest three years after the award date based on the level of the Company's achievement of identified performance targets in comparison to the level of achievement of such identified performance targets by a defined peer group comprised of 17 financial institutions. These are referred to as "performance-based shares". The specific performance measure targets relate to return on assets, return on tangible equity, asset quality and total stockholder return (share price appreciation from date of award plus dividends paid as a percent of the Company's common stock share price on the date of award). If a participant leaves the Company prior to the third anniversary date of an award, any unvested shares are forfeited. Dividends declared with respect to shares awarded will be held by the Company and paid to the participant only when the shares vest.

Under all the Plans, shares of the Company's common stock were reserved for issuance as restricted stock awards to officers, employees, and non-employee directors of the Company. Shares issued upon vesting may be either authorized but unissued shares or reacquired shares held by the Company as treasury shares. Any shares not issued because vesting requirements are not met will be retired back to treasury and be made available again for issuance under the Plans.

Notes to Unaudited Consolidated Financial Statements (Continued)

At and for the Three Months Ended March 31, 2017 and 2016

As of December 31, 2016, the fair value of the foreign exchange contracts was nominal. As of December 31, 2016, the Company held no risk participation-in agreements.

Investment Securities Available-for-Sale

The fair value of investment securities is based principally on market prices and dealer quotes received from third-party and nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's marketable equity securities are priced this way and are included in Level 1. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include GSE debentures, GSE mortgage-related securities, SBA commercial loan asset backed securities, corporate debt securities, and trust preferred securities, all of which are included in Level 2. As of March 31, 2017 and December 31, 2016, no investment securities were valued using pricing models included in Level 3.

Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with management's expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for a particular security.

Loan Level Derivatives

The fair values for the interest-rate swap assets and liabilities represent a Level 2 valuation and are based on settlement values adjusted for credit risks associated with the counterparties and the Company and observable market interest rate curves. Credit risk adjustments consider factors such as the likelihood of default by the Company and its counterparties, its net exposures and remaining contractual life. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position. Refer also to Note 8, "Derivatives and Hedging Activities."

There were no transfers between levels for assets and liabilities recorded at fair value on a recurring basis during the three months ended March 31, 2017 and 2016, respectively.

Collateral-Dependent Impaired Loans and Leases

For nonperforming loans and leases where the credit quality of the borrower has deteriorated significantly, fair values of the underlying collateral were estimated using purchase and sales agreements (Level 2), or comparable sales or recent appraisals (Level 3), adjusted for selling costs and other expenses.

Other Real Estate Owned

The Company records OREO at the lower of cost or fair value. In estimating fair value, the Company utilizes purchase and sales agreements (Level 2) or comparable sales, recent appraisals or cash flows discounted at an interest rate commensurate with the risk associated with these cash flows (Level 3), adjusted for selling costs and other expenses.

Repossessed Assets

Repossessed assets are carried at estimated fair value less costs to sell based on auction pricing (Level 2).

The table below presents quantitative information about significant unobservable inputs (Level 3) for assets measured at fair value on a recurring basis at the dates indicated.



	Fair Value				Valuation Technique
	At March 31, 2017		At December 31, 2016

Collateral-dependent impaired loans and leases	$	34,457	$	27,282	Appraisal of collateral ⁽¹⁾
Other real estate owned	618		618		Appraisal of collateral ⁽¹⁾

_______________________________________________________________________________

⁽¹⁾ Fair value is generally determined through independent appraisals of the underlying collateral. The Company may also use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of the unobservable inputs used may vary but is generally 0% - 10% on the discount for costs to sell and 0% - 15% on appraisal adjustments.

Investment Securities Held-to-Maturity

The fair values of certain investment securities held-to-maturity are estimated using market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include GSE debentures, GSE MBSs, and municipal obligations, all of which are included in Level 2. Additionally, fair values of foreign government obligations are based on comparisons to market prices of similar securities and are considered to be Level 3.

Notes to Unaudited Consolidated Financial Statements (Continued)

At and for the Three Months Ended March 31, 2017 and 2016

Loans Held-for-Sale

Fair value is measured using quoted market prices when available. These assets are typically categorized as Level 1. If quoted market prices are not available, comparable market values may be utilized. These assets are typically categorized as Level 2.

Loans and Leases

The fair values of performing loans and leases was estimated by segregating the portfolio into its primary loan and lease categories—commercial real estate mortgage, multi-family mortgage, construction, commercial, equipment financing, condominium association, residential mortgage, home equity and other consumer. These categories were further disaggregated based upon significant financial characteristics such as type of interest rate (fixed / variable) and payment status (current / past-due). The Company discounts the contractual cash flows for each loan category using interest rates currently being offered for loans with similar terms to borrowers of similar quality and incorporates estimates of future loan prepayments. This method of estimating fair value does not incorporate the exit price concept of fair value.

Restricted Equity Securities

The fair values of certain restricted equity securities are estimated using observable inputs adjusted for other unobservable information, including but not limited to probability assumptions and similar discounts where applicable. These restricted equity securities are considered to be Level 3.

Deposits

The fair values of deposit liabilities with no stated maturity (demand, NOW, savings and money market savings accounts) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. The fair value estimates for deposits do not include the benefit that results from the low-cost funding provided by the Company's core deposit relationships (deposit-based intangibles).

Borrowed Funds

The fair value of federal funds purchased is equal to the amount borrowed. The fair value of FHLBB advances and repurchase agreements represents contractual repayments discounted using interest rates currently available for borrowings with similar characteristics and remaining maturities. The fair values reported for retail repurchase agreements are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on borrowings with similar characteristics and maturities. The fair values reported for subordinated deferrable interest debentures are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on instruments with similar terms and maturities.

(12) Commitments and Contingencies

Off-Balance Sheet Financial Instruments

The Company is party to off-balance sheet financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby and commercial letters of credits, and loan level derivatives. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received.

The contract amounts reflect the extent of the involvement the Company has in particular classes of these instruments. Such commitments involve, to varying degrees, elements of credit risk and interest-rate risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of non-performance by the counterparty is represented by the fair value of the instruments. The Company uses the same policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee by the customer. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if any, is based on management's credit evaluation of the borrower.

Standby and commercial letters of credits are conditional commitments issued by the Company to guarantee performance of a customer to a third party. These standby and commercial letters of credit are primarily issued to support the financing needs of the Company's commercial customers. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.

The liability for unfunded credit commitments, which is included in other liabilities, was $1.4 million and $1.5 million as of March 31, 2017 and December 31, 2016, respectively.

From time to time, the Company enters into loan level derivatives, risk participation agreements or foreign exchange contracts with commercial customers and third-party financial institutions. These derivatives allow the Company to offer long-term fixed-rate commercial loans while mitigating the interest-rate or foreign exchange risk of holding those loans. In a loan level derivative transaction, the Company lends to a commercial customer on a floating-rate basis and then enters into an loan level derivative with that customer. Concurrently, the Company enters into offsetting swaps with a third-party financial institution, effectively minimizing its net interest-rate risk exposure resulting from such transactions.

The fair value of derivative assets and liabilities was $9.4 million and $9.4 million, respectively, as of March 31, 2017. The fair value of derivative assets and liabilities was $9.8 million and $9.7 million, respectively, as of December 31, 2016.

Lease Commitments

The Company leases certain office space under various noncancellable operating leases. These leases have original terms ranging from 5 years to over 25 years. Certain leases contain renewal options and escalation clauses which can increase rental expenses based principally on the consumer price index and fair market rental value provisions.

A summary of future minimum rental payments under such leases at the dates indicated follows:



	Minimum Rental Payments
	(In Thousands)

Remainder of 2017	$	4,076
Year ending:
2018	5,034
2019	4,165
2020	3,609
2021	3,100
2022	2,878
Thereafter	11,045
Total	$	33,907

Certain leases contain escalation clauses for real estate taxes and other expenditures, which are not included above. Total rental expense was $1.4 million and $1.3 million for the three months ended March 31, 2017 and 2016, respectively. The increase was due to the opening of a new branch in Danvers, Massachusetts for First Ipswich Bank, and the relocation of a branch in Brookline, Massachusetts for Brookline Bank.

Legal Proceedings

In the normal course of business, there are various outstanding legal proceedings. In the opinion of management, after consulting with legal counsel, the consolidated financial position and results of operations of the Company are not expected to be affected materially by the outcome of such proceedings.

(13) Subsequent Events

On, April 27, 2017, the Company entered into an underwriting agreement with Piper Jaffray & Co., as representative of the underwriters named therein (collectively, the “Underwriters”), to offer and sell 5,175,000 shares of the Company’s common stock, $0.01 par value per share at a public offering price of $14.50 per share in an underwritten public offering (the “Offering”). In conjunction with the Offering, the Company granted the Underwriters a 30-day option to purchase up to an additional 776,250 shares of its Common Stock. On May 2, 2017, the Company and the Underwriters closed the Offering. The Underwriters exercised their option resulting in a new issuance in the aggregate of 5,951,250 shares of the Company’s common stock at a price to the public of $14.50 per share. The Company received net proceeds of $82.0 million after deductions for underwriting discounts, commissions, and expenses.

Introduction

Brookline Bancorp, Inc., a Delaware corporation, operates as a multi-bank holding company for Brookline Bank and its subsidiaries; Bank Rhode Island and its subsidiaries; First Ipswich Bank and its subsidiaries; and Brookline Securities Corp.

As a commercially-focused financial institution with 51 full-service banking offices throughout greater Boston, the north shore of Massachusetts and Rhode Island, the Company, through Brookline Bank, BankRI and First Ipswich (the “Banks”), offers a wide range of commercial, business and retail banking services, including a full complement of cash management products, on-line and mobile banking services, consumer and residential loans and investment services, designed to meet the financial needs of small- to mid-sized businesses and individuals throughout central New England. Specialty lending activities include equipment financing primarily in the New York and New Jersey metropolitan area.

The Company focuses its business efforts on profitably growing its commercial lending businesses, both organically and through acquisitions. The Company’s customer focus, multi-bank structure, and risk management are integral to its organic growth strategy and serve to differentiate the Company from its competitors. As full-service financial institutions, the Banks and their subsidiaries focus their efforts on developing and deepening long-term banking relationships with qualified customers through a full complement of products and excellent customer service, and strong risk management.

The Company manages the Banks under uniform strategic objectives, with one set of uniform policies consistently applied by one executive management team. Within this environment, the Company believes that the ability to make customer decisions locally enhances management's motivation, service levels and, as a consequence, the Company's financial results. As such, while most back-office functions are consolidated at the holding company level, branding and decision-making, including credit decisions and pricing, remain largely local in order to better meet the needs of bank customers and further motivate the Banks’ commercial, business and retail bankers.

The competition for loans and leases and deposits remains intense. While the economy has improved in 2017, the Company expects the operating environment in 2018 to remain challenging. The volume of loan and lease originations and loan and lease losses will depend, to a large extent, on how the economy performs. Loan and lease growth and deposit growth are also greatly influenced by the rate-setting actions of the Board of Governors of the Federal Reserve System (“FRB”). A sustained, low interest rate environment may continue to have a negative impact on the Company's yields and net interest

Table of Contents

margin. Rising rates in the future could cause changes in the mix and volume of the Company's deposits and make it more difficult for certain borrowers to be eligible for new loans or leases or to service their existing debt. The future operating results of the Company will depend on its ability to maintain the net interest margin, while minimizing exposure to credit risk, along with increasing sources of non-interest income, while controlling the growth of non-interest or operating expenses.

The Company and the Banks are supervised, examined and regulated by the FRB. As a Massachusetts-chartered savings bank and trust company, respectively, Brookline Bank and First Ipswich are also subject to regulation under the laws of the Commonwealth of Massachusetts and the jurisdiction of the Massachusetts Division of Banks. As a Rhode Island-chartered financial institution, BankRI is also subject to regulation under the laws of the State of Rhode Island and the jurisdiction of the Banking Division of the Rhode Island Department of Business Regulation. The FDIC continues to insure each of the Banks’ deposits up to $250,000 per depositor. Additionally, as a Massachusetts-chartered savings bank, Brookline Bank is also insured by the Depositors Insurance Fund (“DIF”), a private industry-sponsored company. The DIF insures savings bank deposits in excess of the FDIC insurance limits. As such, Brookline Bank offers 100% insurance on all deposits as a result of a combination of insurance from the FDIC and the DIF.

The Company’s common stock is traded on the Nasdaq Global Select Market^SM under the symbol “BRKL.”

Executive Overview

Growth

Total assets of $6.5 billion as of March 31, 2017 increased $59.6 million, or 3.6% on an annualized basis, from December 31, 2016. The increase was primarily driven by increases in loans and leases.

Total loans and leases of $5.5 billion as of March 31, 2017 increased $62.9 million, or 4.8% on an annualized basis, from December 31, 2016. The Company's commercial loan portfolios, which are comprised of commercial real estate loans and commercial loans and leases, totaled $4.5 billion, or 81.9% of total loans and leases, as of March 31, 2017, an increase of $57.6 million, or 5.2% on an annualized basis, from $4.4 billion, or 81.8% of total loans and leases, as of December 31, 2016.

Total deposits of $4.7 billion as of March 31, 2017 increased $40.8 million, or 3.6% on an annualized basis, from $4.6 billion as of December 31, 2016. Core deposits, which include demand checking, NOW, money market and savings accounts, totaled $3.6 billion, or 76.6% of total deposits as of March 31, 2017, a decrease of $8.8 million, or 1.0% on an annualized basis, from $3.6 billion, or 77.4% of total deposits, as of December 31, 2016.

Asset Quality

Nonperforming assets as of March 31, 2017 totaled $47.3 million, or 0.73% of total assets, compared to $41.5 million, or 0.64% of total assets, as of December 31, 2016. Net charge-offs for the three months ended March 31, 2017 were $1.0 million, or 0.07% of average loans and leases on an annualized basis, compared to $0.4 million, or 0.03% of average loans and leases on an annualized basis, for the three months ended March 31, 2016.The increase in nonperforming loans and leases and nonperforming assets was primarily driven by two taxi medallion loans and two commercial loans that were placed on nonaccrual.

Table of Contents

The ratio of the allowance for loan and lease losses to total loans and leases was 1.21% as of March 31, 2017, compared to 0.99% as of December 31, 2016. Excluding the loans acquired from BankRI and First Ipswich, the allowance for loan and lease losses related to originated loans and leases as a percentage of the total originated loan and lease portfolio was 1.25% as of March 31, 2017, compared to 1.03% as of December 31, 2016. The Company continued to employ its historical underwriting methodology throughout the three month period ended March 31, 2017.

Capital Strength

The Company is a "well-capitalized" bank holding company as defined in the FRB's Regulation Y. The Company's common equity Tier 1 Capital Ratio was 10.57% as of March 31, 2017, compared to 10.48% as of December 31, 2016. The Company's Tier 1 Leverage Ratio was 9.22% as of March 31, 2017, compared to 9.16% as of December 31, 2016. As of March 31, 2017, the Company's Tier 1 Risk-Based Ratio was 10.88%, compared to 10.79% as of December 31, 2016. The Company's Total Risk-Based Ratio was 13.51% as of March 31, 2017, compared to 13.20% as of December 31, 2016.

The Company's ratio of stockholders' equity to total assets was 10.83% and 10.80% as of March 31, 2017 and December 31, 2016, respectively. The Company's tangible equity ratio was 8.79% and 8.73% as of March 31, 2017 and December 31, 2016, respectively.

Net Income

For the three months ended March 31, 2017, the Company reported net income of $13.4 million, or $0.19 per basic and diluted share, an increase of $0.6 million, or 19.6% on an annualized basis, from $12.8 million, or $0.18 per basic and diluted share for the three months ended March 31, 2016. The increase in net income is primarily the result of an increase in gain on sale of investment securities, net of $11.4 million, partially offset by an increase to provision for credit losses of $11.0 million.

The annualized return on average assets was 0.83% for the three months ended March 31, 2017, compared to 0.84% for the three months ended March 31, 2016. The annualized return on average stockholders' equity was 7.58% for the three months ended March 31, 2017, compared to 7.57% for the three months ended March 31, 2016.

The net interest margin was 3.53% for the three months ended March 31, 2017, up from 3.45% for the three months ended March 31, 2016. The increase in the net interest margin is a result of an increase in the yield on interest-earning assets by 5 basis points to 4.08% for the three months ended March 31, 2017 from 4.03% for the three months ended March 31, 2016, and an increase of 1 basis point in the Company's overall cost of funds to 0.66% for the three months ended March 31, 2017 from 0.65% for the three months ended March 31, 2016.

The Company's net interest margin and net interest income has shown improvement from the most recent low interest rate environment. As interest rates rise, the Company's net interest margin and net interest income may continue to be under pressure due to competitive pricing in all loan categories and the Company’s ability to contain its cost of funds.

Critical Accounting Policies

The SEC defines “critical accounting policies” as those involving significant judgments and difficult or complex assumptions by management, often as a result of the need to make estimates about matters that are inherently uncertain or variable, which have, or could have, a material impact on the carrying value of certain assets or net income. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. As discussed in the Company’s 2016 Annual Report on Form 10-K, management has identified the valuation of available-for-sale securities, accounting for assets and liabilities acquired, the determination of the allowance for loan and lease losses, the review of goodwill and intangibles for impairment, and income tax accounting as the Company’s most critical accounting policies.

Non-GAAP Financial Measures and Reconciliation to GAAP

In addition to evaluating the Company’s results of operations in accordance with GAAP, management periodically supplements this evaluation with an analysis of certain non-GAAP financial measures, such as the return on average tangible assets, return on average tangible equity, the tangible equity ratio, tangible book value per share, dividend payout ratio, and the ratio of the allowance for loan and lease losses related to originated loans and leases as a percentage of originated loans and leases. Management believes that these non-GAAP financial measures provide information useful to investors in understanding the Company’s underlying operating performance and trends, and facilitates comparisons with the performance assessment of financial performance, including non-interest expense control, while the tangible equity ratio and tangible book value per share are used to analyze the relative strength of the Company’s capital position.

Total loans and leases	$	5,461,779	$	5,398,864	$	62,915	4.7	%

The Company's loan portfolio consists primarily of first mortgage loans secured by commercial, multi-family and residential real estate properties located in the Company's primary lending area, loans to business entities, including commercial lines of credit, loans to condominium associations and loans and leases used to finance equipment used by small businesses. The Company also provides financing for construction and development projects, home equity and other consumer loans.

The Company employs seasoned commercial lenders and retail bankers who rely on community and business contacts as well as referrals from customers, attorneys and other professionals to generate loans and deposits. Existing borrowers are also an important source of business since many of them have more than one loan outstanding with the Company. The Company's ability to originate loans depends on the strength of the economy, trends in interest rates, and levels of customer demand and market competition.

Table of Contents

The Company's current policy is that the aggregate amount of loans outstanding to any one borrower or related entities may not exceed $35.0 million unless approved by the Board Credit Committee, a committee of the Company's Board of Directors.

As of March 31, 2017, there were seven borrowers with commitments over $35.0 million. The total of those commitments was $316.7 million, or 4.97% of total commitments, as of March 31, 2017.

The Company has written underwriting policies to control the inherent risks in loan origination. The policies address approval limits, loan-to-value ratios, appraisal requirements, debt service coverage ratios, loan concentration limits and other matters relevant to loan underwriting.

Commercial Real Estate Loans

The commercial real estate portfolio is comprised of commercial real estate loans, multi-family mortgage loans, and construction loans and is the largest component of the Company's overall loan portfolio, representing 54.0% of total loans and leases outstanding as of March 31, 2017.

Typically, commercial real estate loans are larger in size and involve a greater degree of risk than owner-occupied residential mortgage loans. Loan repayment is usually dependent on the successful operation and management of the properties and the value of the properties securing the loans. Economic conditions can greatly affect cash flows and property values.

A number of factors are considered in originating commercial real estate and multi-family mortgage loans. The qualifications and financial condition of the borrower (including credit history), as well as the potential income generation and the value and condition of the underlying property, are evaluated. When evaluating the qualifications of the borrower, the Company considers the financial resources of the borrower, the borrower's experience in owning or managing similar property and the borrower's payment history with the Company and other financial institutions. Factors considered in evaluating the underlying property include the net operating income of the mortgaged premises before debt service and depreciation, the debt service coverage ratio (the ratio of cash flow before debt service to debt service), the use of conservative capitalization rates, and the ratio of the loan amount to the appraised value. Generally, personal guarantees are obtained from commercial real estate loan borrowers.

Commercial real estate and multi-family mortgage loans are typically originated for terms of five to fifteen years with amortization periods of 20 to 30 years. Many of the loans are priced at inception on a fixed-rate basis generally for periods ranging from two to five years with repricing periods for longer-term loans. When possible, prepayment penalties are included in loan covenants on these loans. For commercial customers who are interested in loans with terms longer than five years, the Company offers loan level derivatives to accommodate customer need.

The Company's urban and suburban market area is characterized by a large number of apartment buildings, condominiums and office buildings. As a result, commercial real estate and multi-family mortgage lending has been a significant part of the Company's activities for many years. These types of loans typically generate higher yields, but also involve greater credit risk. Many of the Company's borrowers have more than one multi-family or commercial real estate loan outstanding with the Company.

The commercial real estate portfolio is composed primarily of loans secured by apartment buildings ($756.6 million), office buildings ($642.0 million), retail stores ($548.2 million), industrial properties ($335.7 million) and mixed-use properties ($202.9 million) as of March 31, 2017. At that date, over 97% of the commercial real estate loans outstanding were secured by properties located in New England.

Construction and development financing is generally considered to involve a higher degree of risk than long-term financing on improved, occupied real estate and thus has lower concentration limits than do other commercial credit classes. Risk of loss on a construction loan is largely dependent upon the accuracy of the initial estimate of construction costs, the estimated time to sell or rent the completed property at an adequate price or rate of occupancy, and market conditions. If the estimates and projections prove to be inaccurate, the Company may be confronted with a project which, upon completion, has a value that is insufficient to assure full loan repayment.

Criteria applied in underwriting construction loans for which the primary source of repayment is the sale of the property are different from the criteria applied in underwriting construction loans for which the primary source of repayment is the stabilized cash flow from the completed project. For those loans where the primary source of repayment is from resale of the property, in addition to the normal credit analysis performed for other loans, the Company also analyzes project costs, the attractiveness of the property in relation to the market in which it is located and demand within the market area. For those construction loans where the source of repayment is the stabilized cash flow from the completed project, the Company analyzes

not only project costs but also how long it might take to achieve satisfactory occupancy and the reasonableness of projected rental rates in relation to market rental rates.

Commercial Loans

The commercial loan and lease portfolio is comprised of commercial loans, equipment financing loans and leases and condominium association loans and represented 27.8% of total loans outstanding as of March 31, 2017.

The Company provides commercial banking services to companies in its market area. Approximately 49% of the commercial loans outstanding as of March 31, 2017 were made to borrowers located in New England. The remaining 51% of the commercial loans outstanding were made to borrowers in other areas in the United States of America, primarily by the Company's equipment financing divisions. Product offerings include lines of credit, term loans, letters of credit, deposit services and cash management. These types of credit facilities have as their primary source of repayment cash flows from the operations of a business. Interest rates offered are available on a floating basis tied to the prime rate or a similar index or on a fixed-rate basis referenced on the Federal Home Loan Bank of Boston ("FHLBB") index.

Credit extensions are made to established businesses on the basis of loan purpose and assessment of capacity to repay as determined by an analysis of their financial statements, the nature of collateral to secure the credit extension and, in most instances, the personal guarantee of the owner of the business as well as industry and general economic conditions. The Company also participates in U.S. Government programs such as the Small Business Administration (the "SBA") in both the 7A program and as an SBA preferred lender.

The Company’s equipment financing divisions focus on market niches in which its lenders have deep experience and industry contacts, and on making loans to customers with business experience. An important part of the Company’s equipment financing loan origination volume comes from equipment manufacturers and existing customers as they expand their operations. The equipment financing portfolio is composed primarily of loans to finance laundry, tow trucks, fitness, dry cleaning and convenience store equipment. Approximately 17% of the commercial loans outstanding were made to borrowers located primarily in the greater New York and New Jersey metropolitan area. Typically, the loans are priced at a fixed rate of interest and require monthly payments over their three- to seven-year life. The yields earned on equipment financing loans are higher than those earned on the commercial loans made by the Banks because they involve a higher degree of credit risk. Equipment financing customers are typically small-business owners who operate with limited financial resources and who face greater risks when the economy weakens or unforeseen adverse events arise. Because of these characteristics, personal guarantees of borrowers are usually obtained along with liens on available assets. The size of loan is determined by an analysis of cash flow and other characteristics pertaining to the business and the equipment to be financed, based on detailed revenue and profitability data of similar operations.

Loans to condominium associations are for the purpose of funding capital improvements, are made for five- to ten-year terms and are secured by a general assignment of condominium association revenues. Among the factors considered in the underwriting of such loans are the level of owner occupancy, the financial condition and history of the condominium association, the attractiveness of the property in relation to the market in which it is located and the reasonableness of estimates of the cost of capital improvements to be made. Depending on loan size, funds are advanced as capital improvements are made and, in more complex situations, after completion of engineering inspections.

Consumer Loans

The consumer loan portfolio is comprised of residential mortgage loans, home equity loans and lines of credit, and other consumer loans and represented 18.2% of total loans outstanding as of March 31, 2017. The Company focuses its mortgage and home equity lending on existing and new customers within its branch networks in its urban and suburban marketplaces in the greater Boston and Providence metropolitan areas.

The Company originates adjustable- and fixed-rate residential mortgage loans secured by one- to four-family residences. Each residential mortgage loan granted is subject to a satisfactorily completed application, employment verification, credit history and a demonstrated ability to repay the debt. Generally, loans are not made when the loan-to-value ratio exceeds 80% unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Appraisals are performed by outside independent fee appraisers.

In general, the Company maintains three-, five- and seven-year adjustable-rate mortgage loans and ten-year fixed-rate fully amortizing mortgage loans in its portfolio. Fixed-rate mortgage loans with maturities beyond ten years, such as 15- and 30-year fixed-rate mortgages, are generally sold into the secondary market on a servicing-released basis. The Banks act as correspondent banks in these secondary-market transactions. Loan sales in the secondary market provide funds for additional lending and other banking activities.

Underwriting guidelines for home equity loans and lines of credit are similar to those for residential mortgage loans. Home equity loans and lines of credit are limited to no more than 80% of the appraised value of the property securing the loan including the amount of any existing first mortgage liens.

Other consumer loans have historically been a modest part of the Company's loan originations. As of March 31, 2017, other consumer loans equaled $15.0 million, or 0.3% of total loans outstanding. Loans outstanding in other consumer included indirect automobile loans of $4.8 million and loans secured by cash, equity, and debt securities.

Asset Quality

Criticized and Classified Assets

The Company's management rates certain loans and leases as "other assets especially mentioned ("OAEM")", "substandard" or "doubtful" based on criteria established under banking regulations.These loans and leases are collectively referred to as "criticized" assets. Loans and leases rated OAEM have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects of the loan or lease at some future date. Loans and leases rated as substandard are inadequately protected by the payment capacity of the obligor or of the collateral pledged, if any. Substandard loans and leases have a well-defined weakness or weaknesses that jeopardize the liquidation of debt and are characterized by the distinct possibility that the Company will sustain some loss if existing deficiencies are not corrected. Loans and leases rated as doubtful have well-defined weaknesses that jeopardize the orderly liquidation of debt and partial loss of principal is likely. As of March 31, 2017, the Company had $73.5 million of total assets, including acquired assets, that were designated as criticized. This compares to $70.5 million of assets designated as criticized as of December 31, 2016. The increase in criticized assets was primarily due to two commercial real estate relationships which were downgraded, offset by the payoffs of several criticized loans during the first quarter of 2017.

Nonperforming Assets

"Nonperforming assets" consist of nonperforming loans and leases, other real estate owned ("OREO") and other repossessed assets. Under certain circumstances, the Company may restructure the terms of a loan or lease as a concession to a borrower, except for acquired loans and leases which are individually evaluated against expected performance on the date of acquisition. These restructured loans and leases are generally considered "nonperforming loans and leases" until a history of collection of at least six months on the restructured terms of the loan or lease has been established. OREO consists of real estate acquired through foreclosure proceedings and real estate acquired through acceptance of a deed in lieu of foreclosure. Other repossessed assets consist of assets that have been acquired through foreclosure that are not real estate and are included in other assets on the Company's unaudited consolidated balance sheets.

Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in management's judgment, reasonable doubt exists as to the full timely collection of interest. Exceptions may be made if the loan has matured and is in the process of renewal or is well-secured and in the process of collection. When a loan is placed on nonaccrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current interest income. Interest payments on nonaccrual loans are generally applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are generally returned to accrual status when principal and interest payments are current, full collectability of principal and interest is reasonably assured and a consistent record of at least six months of performance has been achieved.

In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a troubled debt restructured loan. In determining whether a debtor is experiencing financial difficulties, the Company considers, among other factors, if the debtor is in payment default or is likely to be in payment default in the foreseeable future without the modification, the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor's entity-specific projected cash flows will not be sufficient to service its debt, or the debtor cannot obtain funds from sources other than the existing creditors at market terms for debt with similar risk characteristics.

Nonperforming assets are composed of nonaccrual loans and leases, OREO and other repossessed assets. As of March 31, 2017, the Company had nonperforming assets of $47.3 million, representing 0.73% of total assets, compared to nonperforming assets of $41.5 million, or 0.64% of total assets, as of December 31, 2016. The increase in nonperforming assets was primarily due to a commercial loan with a balance of $4.9 million which was placed on nonaccrual status and an increase of $0.9 million in repossessed assets as of March 31, 2017.

The Company evaluates the underlying collateral of each nonperforming loan and lease and continues to pursue the collection of interest and principal. Management believes that the current level of nonperforming assets remains manageable relative to the size of the Company's loan and lease portfolio. If economic conditions were to worsen or if the marketplace were

to experience prolonged economic stress, management believes it is likely that the level of nonperforming assets would increase, as would the level of charged-off loans.

Past Due and Accruing

As of March 31, 2017, the Company had loans and leases greater than 90 days past due and accruing of $6.5 million, or 0.12% of total loans and leases, compared to $7.1 million, or 0.13% of total loans and leases, as of December 31, 2016, representing an decrease of $0.6 million.

Allowances for Credit Losses

The allowance for loan and lease losses consists of general and specific allowances and reflects management's estimate of probable loan and lease losses inherent in the loan portfolio at the balance sheet date. Management uses a consistent and systematic process and methodology to evaluate the adequacy of the allowance for loan and lease losses on a quarterly basis. The allowance is calculated by loan type: commercial real estate loans, commercial loans and leases, and consumer loans, each category of which is further segregated. A formula-based credit evaluation approach is applied to each group that is evaluated collectively, primarily by loss factors, which includes estimates of incurred losses over an estimated LEP, assigned to each risk rating by type, coupled with an analysis of certain loans individually evaluated for impairment. Management continuously evaluates and challenges inputs and assumptions in the allowance for loan and lease loss.

The process to determine the allowance for loan and lease losses requires management to exercise considerable judgment regarding the risk characteristics of the loan portfolios and the effect of relevant internal and external factors. While management evaluates currently available information in establishing the allowance for loan and lease losses, future adjustments to the allowance for loan and lease losses may be necessary if conditions differ substantially from the assumptions used in making the evaluations. Management performs a comprehensive review of the allowance for loan and lease losses on a quarterly basis. In addition, various regulatory agencies, as an integral part of their examination process, periodically review a financial institution's allowance for loan and lease losses and carrying amounts of other real estate owned. Such agencies may require the financial institution to recognize additions to the allowance based on their judgments about information available to them at the time of their examination.

The Company’s general allowance methodology provides a precise quantification of probable losses in the portfolio. Under the current methodology, Management combines the historical loss information of the Banks to generate a single set of ratios. Management believes it is appropriate to aggregate the ratios as the Banks share common environmental factors, operate in similar markets, and utilize common underwriting standards in accordance with the Company's Credit Policy. In prior periods, a historical loss history applicable to each Bank was used.

Table of Contents

Management employs a similar analysis for the consolidation of the qualitative factors as it does for the quantitative factors. Again, Management believes the combination of the existing nine qualitative factors used at each of the Banks into a single group of factors for use across the Company is appropriate based on the commonality of environmental factors, markets, and underwriting standards among the Banks. In prior periods each of the Banks utilized a set of qualitative factors applicable to each Bank.

The following tables present the changes in the allowance for loan and lease losses by portfolio category for the three months ended March 31, 2017 and 2016.

Total allowance for loan and lease losses as a percentage of total loans and leases	1.12		%	1.64		%	0.48		%	1.14		%

The allowance for loan and lease losses was $66.1 million as of March 31, 2017, or 1.21% of total loans and leases outstanding. This compared to an allowance for loan and lease losses of $53.7 million, or 0.99% of total loans and leases outstanding, as of December 31, 2016. The increase in the allowance for loan and lease losses and in the allowance for loan and lease losses as a percentage of total loans and leases from December 31, 2016 to March 31, 2017 was primarily due to the increase in specific reserves for taxi medallion loans as a result of a change in the underlying collateral value, the increase in

Table of Contents

the specific reserve of two commercial loans, the increase in historical loss factors applied to commercial loan portfolios including taxi medallion loans, and loan growth of $62.9 million during the first quarter of 2017.

Management believes that the allowance for loan and lease losses as of March 31, 2017 is appropriate based on the facts and circumstances discussed further below.

Commercial Real Estate Loans

The allowance for commercial real estate loan losses was $28.0 million, or 0.95% of total commercial real estate loans outstanding, as of March 31, 2017. This compared to an allowance for commercial real estate loan losses of $27.6 million, or 0.95% of total commercial real estate loans outstanding, as of December 31, 2016. Specific reserves on commercial real estate loans were $54.0 thousand and $28.0 thousand as of March 31, 2017 and December 31, 2016, respectively. The $0.4 million increase in the allowance for commercial real estate loan losses during the first three months of 2017 was primarily driven by originated loan growth of $42.9 million, or 1.6% from December 31, 2016.

The ratio of total criticized and classified commercial real estate loans to total commercial real estate loans increased to 0.84% as of March 31, 2017 from 0.74% as of December 31, 2016. The ratio of originated commercial real estate loans on nonaccrual to total originated commercial real estate loans increased to 0.24% as of March 31, 2017 from 0.23% as of December 31, 2016.

Net recoveries in the commercial real estate loan portfolio totaled $0.1 million for the three months ended March 31, 2017, compared to net charge-offs of $0.3 million for the three months ended March 31, 2016. As a percentage of average commercial real estate loan portfolio, annualized net recoveries for the three months ended March 31, 2017 was 0.02% and annualized charge-offs for the three month ended March 31, 2016 was 0.05%.

Commercial Loans and Leases

The allowance for commercial loan and lease losses was $33.3 million, or 2.19% of total commercial loans and leases outstanding, as of March 31, 2017, compared to $20.9 million, or 1.40% of total commercial loans and leases outstanding, as of December 31, 2016. Specific reserves on commercial loans and leases increased from $0.1 million as of December 31, 2016 to $10.0 million as of March 31, 2017. The $12.4 million increase in the allowance for commercial loans and lease losses during 2017 was primarily due to the increase in specific reserves for taxi medallion loans as a result of a change in the underlying collateral value, the increase in the specific reserve of two commercial loans, the increase in historical loss factors applied to commercial loan portfolios including taxi medallion portfolio in the first quarter of 2017, and the originated loan growth of 29.4 million, or 2.0% from December 31, 2016.

The ratio of total criticized and classified commercial loans and leases to total commercial loans and leases was 3.19% as of March 31, 2017, compared to 3.27% as of December 31, 2016. The ratio of originated commercial loans and leases on nonaccrual to total originated commercial loans and leases increased to 2.14% as of March 31, 2017 from 1.85% as of December 31, 2016 primarily due to several commercial loans which were not accruing in the first quarter of 2017.

Net charge-offs in the commercial loan and lease portfolio for the three months ended March 31, 2017 and March 31, 2016 were $1.1 million and $0.1 million, respectively. As a percentage of average commercial loans and leases, annualized net charge-offs for the three months ended March 31, 2017 and March 31, 2016 were 0.29% and 0.02%, respectively.

Consumer Loans

The allowance for consumer loan losses, including residential loans and home equity loans and lines of credit, was $4.9 million, or 0.49% of total consumer loans outstanding, as of March 31, 2017, compared to $5.1 million, or 0.52% of consumer loans outstanding, as of December 31, 2016. Specific reserves on consumer loans were $20.0 thousand and $27.0 thousand as of March 31, 2017 and December 31, 2016, respectively. The $0.2 million decrease in the allowance for consumer loans during the first quarter of 2017 was primarily driven by the decrease in the historical loss factors applied to the consumer portfolios offset by the originated loan growth of $10.9 million, or 1.3%, from December 31, 2016. The ratio of originated consumer loans on nonaccrual to total originated consumer loans increased to 0.42% as of March 31, 2017 from 0.32% as of December 31, 2016. The risk of loss on a home equity loan is higher since the property securing the loan has often been previously pledged as collateral for a first mortgage loan. The Company gathers and analyzes delinquency data, to the extent that data are available on these first liens, for purposes of assessing the collectability of the second liens held by the Company even if these home equity loans are not delinquent. This data are further analyzed for performance differences between amortizing and non-amortizing home equity loans, the percentage borrowed to total loan commitment and by the amount of payments made by the borrowers. The loss exposure is not considered to be high due to the combination of current property values, the historically low loan-to-value ratios, the low level of losses experienced in the past few years and the low level of

Table of Contents

loan delinquencies as of March 31, 2017. If the local economy weakens, however, a rise in losses in those loan classes could occur. Historically, losses in these classes have been low.

Net charge-offs in the consumer loan portfolio totaled $46.0 thousand for the three months ended March 31, 2017, compared to net recoveries of $5.0 thousand for the three months ended March 31, 2016. Provisions for consumer loans recorded in these periods more than adequately covered charge-offs during those periods.

The following table sets forth the Company's percent of allowance for loan and lease losses to the total allowance for loan and lease losses and the percent of loans to total loans for each of the categories listed at the dates indicated.

Investment Securities

The investment portfolio exists primarily for liquidity purposes, and secondarily as sources of interest and dividend income, interest-rate risk management and tax planning as a counterbalance to loan and deposit flows. Investment securities are utilized as part of the Company's asset/liability management and may be sold in response to, or in anticipation of, factors such as changes in market conditions and interest rates, security prepayment rates, deposit outflows, liquidity concentrations and regulatory capital requirements.

The investment policy of the Company, which is reviewed and approved by the Board of Directors on an annual basis, specifies the types of investments that are acceptable, required investment ratings by at least one nationally recognized rating agency, concentration limits and duration guidelines. Compliance with the investment policy is monitored on a regular basis. In general, the Company seeks to maintain a high degree of liquidity and targets cash, cash equivalents and investment securities available-for-sale balances between 10% and 30% of total assets.

Cash, cash equivalents, and investment securities increased $13.5 million, or 7.9% on an annualized basis, to $691.9 million as of March 31, 2017 from $678.4 million as of December 31, 2016. The increase was primarily driven by an increase in deposit balances, offset by growth in loans and leases and investment securities. Cash, cash equivalents, and investment securities were 10.6% of total assets as of March 31, 2017, compared to 10.5% of total assets at December 31, 2016.

The fair value of investment securities is based principally on market prices and dealer quotes received from third-party, nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's marketable equity securities are priced this way and are included in Level 1. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include certain U.S. and government agency debt securities, municipal and corporate debt securities, GSE residential MBSs and CMOs, and trust preferred securities, all of which are included in Level 2. Certain fair values are estimated using pricing models and are included in Level 3.

Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with their expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for the particular security.

Maturities, calls and principal repayments for investment securities available-for-sale totaled $19.6 million for the three months ended March 31, 2017 compared to $27.6 million for the same period in 2016. There were no sales of investment securities available-for-sale for the three months ended March 31, 2017 and 2016. For the three months ended March 31, 2017, the Company purchased $23.9 million of investment securities available-for-sale, compared to $42.0 million in purchases of investment securities available-for-sale for the same period in 2016.

Maturities, calls and principal repayments for investment securities held-to-maturity totaled $1.3 million for the three months ended March 31, 2017 compared to $13.8 million for the same period in 2016. There were no sales of investment securities held-to-maturity for the three months ended March 31, 2017 and 2016. For the three months ended March 31, 2017, the Company purchased $14.9 million of investment securities held-to-maturity, compared to $3.5 million in purchases of investment securities held-to-maturity for the same period in 2016.

The Company's unrealized loss position decreased in 2017 driven by lower quarter over quarter interest rates and a change in the portfolio mix from shorter duration GSE MBSs to longer duration GSE debentures.

As of March 31, 2017, the fair value of all investment securities held-to-maturity was $99.5 million and carried a total of $1.2 million of net unrealized losses, compared to a fair value of $85.3 million and net unrealized losses of $1.8 million as of December 31, 2016. As of March 31, 2017, $67.2 million, or 66.8%, of the portfolio, had gross unrealized losses of $1.3 million. This compares to $82.0 million, or 94.1%, of the portfolio with gross unrealized losses of $1.9 million as of December 31, 2016. The Company's unrealized loss position decreased in 2017 driven by lower quarter over quarter interest rates and a change in the portfolio mix from shorter duration GSE MBSs to longer duration GSE debentures.

Management believes that these negative differences between amortized cost and fair value do not include credit losses, but rather differences in interest rates between the time of purchase and the time of measurement. It is more likely than not that the Company will not sell the investment securities before recovery, and, as a result, it will recover the amortized cost basis of the investment securities. As such, management has determined that the securities are not other-than-temporarily impaired as of March 31, 2017. If market conditions for securities worsen or the creditworthiness of the underlying issuers deteriorates, it is possible that the Company may recognize additional other-than-temporary impairments in future periods.

Total deposits increased $40.8 million, or 3.5% on an annualized basis, to $4.7 billion as of March 31, 2017, compared to $4.6 billion as of December 31, 2016. Deposits as a percentage of total assets was unchanged at 71.6% as of March 31, 2017, as compared to December 31, 2016. The increase in deposits is primarily due to the growth in certificate of deposit accounts.

As of March 31, 2017, the Company had $266.2 million of brokered deposits compared to $203.4 million as of December 31, 2016. Brokered deposits allow the Company to seek additional funding by attracting deposits from outside the Company's core market. The Company's investment policy limits the amount of brokered deposits to 15% of total assets. Brokered deposits are included in the certificate of deposit balance, which increased $49.6 million, or 19.1% on an annualized basis, during the three months ended March 31, 2017. Certificates of deposit have also increased as a percentage of total deposits to 23.4% as of March 31, 2017 from 22.6% as of December 31, 2016.

During the three months ended March 31, 2017, core deposits decreased $8.8 million, or 1.0% on an annualized basis. The ratio of core deposits to total deposits decreased from 77.4% as of December 31, 2016 to 76.6% as of March 31, 2017, primarily due to the shift in deposit mix and increase in brokered deposits.

Advances from the FHLBB

On a long-term basis, the Company intends to continue to increase its core deposits. The Company also uses FHLBB borrowings and other wholesale borrowing as part of the Company's overall strategy to fund loan growth and manage interest-rate risk and liquidity. The advances are secured by a blanket security agreement which requires the Banks to maintain certain qualifying assets as collateral, principally mortgage loans and securities in an aggregate amount at least equal to outstanding advances. The maximum amount that the FHLBB will advance to member institutions, including the Company, fluctuates from time to time in accordance with the policies of the FHLBB. The Company may also borrow from the FRB's "discount window" as necessary.

FHLBB borrowings increased by $19.2 million to $930.0 million as of March 31, 2017 from the December 31, 2016 balance of $910.8 million. The increase in FHLBB borrowings was primarily due to new advances from the FHLBB in order to fund new loan growth.

Repurchase Agreements

The Company periodically enters into repurchase agreements with its larger deposit and commercial customers as part of its cash management services which are typically overnight borrowings. Short-term borrowings and repurchase agreements with customers decreased $6.6 million to $43.6 million as of March 31, 2017 from $50.2 million as of December 31, 2016.

Subordinated Debentures and Notes

The Company acquired two $5.0 million subordinated debentures due on June 26, 2033 and March 17, 2034, respectively. The Company is obligated to pay 3-month LIBOR plus 3.10% and 3-month LIBOR plus 2.79%, respectively, on a quarterly basis until the debentures mature.

The Company sold $75.0 million of 6.0% fixed-to-floating subordinated notes due September 15, 2029. The Company is obligated to pay 6.0% interest semiannually between September 2014 and September 2024. Subsequently, the Company is obligated to pay 3-month LIBOR plus 3.315% quarterly until the notes mature in September 2029.

Stockholders' Equity and Dividends

The Company's total stockholders' equity was $703.9 million as of March 31, 2017, representing a $8.3 million increase compared to $695.5 million at December 31, 2016. The increase is due to net income of $13.4 million for the three months ended March 31, 2017, which was partially offset by dividends paid by the Company of $6.4 million in that same period.

Stockholders' equity represented 10.83% of total assets as of March 31, 2017 and 10.80% of total assets as of December 31, 2016. Tangible stockholders' equity (total stockholders' equity less goodwill and identified intangible assets, net) represented 8.79% of tangible assets (total assets less goodwill and identified intangible assets, net) as of March 31, 2017 and 8.73% as of December 31, 2016.

For the three months ended March 31, 2017, the dividend payout ratio was 47.23%, compared to 49.45% for the three months ended March 31, 2016.

Results of Operations

The primary drivers of the Company's net income are net interest income, which is strongly affected by the net yield on and growth of interest-earning assets and liabilities ("net interest margin"), the quality of the Company's assets, its levels of non-interest income and non-interest expense, and its tax provision.

The Company's net interest income represents the difference between interest income earned on its investments, loans and leases, and its cost of funds. Interest income is dependent on the amount of interest-earning assets outstanding during the period and the yield earned thereon. Cost of funds is a function of the average amount of deposits and borrowed money outstanding during the year and the interest rates paid thereon. The net interest margin is calculated by dividing net interest income by average interest-earning assets. Net interest spread is the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities. The increases or decreases, as applicable, in the components of interest income and interest expense, expressed in terms of fluctuation in average volume and rate, are summarized under "Rate/Volume Analysis" below. Information as to the components of interest income, interest expense and average rates is provided under "Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin" below.

Because the Company's assets and liabilities are not identical in duration and in repricing dates, the differential between the two is vulnerable to changes in market interest rates as well as the overall shape of the yield curve. These vulnerabilities are inherent to the business of banking and are commonly referred to as "interest-rate risk." How interest-rate risk is measured and, once measured, how much interest-rate risk is taken are based on numerous assumptions and other subjective judgments. See the discussion in “Item 3. Quantitative and Qualitative Disclosures about Market Risk” below.

The quality of the Company's assets also influences its earnings. Loans and leases that are not paid on a timely basis and exhibit other weaknesses can result in the loss of principal and/or interest income. Additionally, the Company must make timely provisions to the allowance for loan and lease losses based on estimates of probable losses inherent in the loan and lease portfolio. These additions, which are charged against earnings, are necessarily greater when greater probable losses are expected. Further, the Company incurs expenses as a result of resolving troubled assets. These variables reflect the "credit risk" that the Company takes on in the ordinary course of business and are further discussed under "Financial Condition—Asset Quality" above.

Net Interest Income

Net interest income increased $3.9 million to $53.1 million for the three months ended March 31, 2017 from $49.2 million for the three months ended March 31, 2016. This overall increase reflects a $4.3 million increase in interest income on loans and leases, and a $0.1 million increase in interest income on investment securities, offset by a $0.6 million increase in interest expense on deposit and borrowings, which is reflective of the various portfolios repricing and replacing balances into the current interest rate environment. Refer to “Results of Operations - Comparison of the Three-Month Period Ended March 31, 2017 and March 31, 2016 — Interest Income” and “Results of Operations - Comparison of the Three-Month Period Ended March 31, 2017 and March 31, 2016 — Interest Expense Deposit and Borrowed Funds” below for more details.

Net interest margin increased by 8 basis points to 3.53% for the three months ended March 31, 2017 from 3.45% for the three months ended March 31, 2016. The Company's weighted average interest rate on loans (prior to purchase accounting adjustments) increased to 4.33% for the three months ended March 31, 2017 from 4.30% for the three months ended March 31, 2016. Interest amortization and accretion on acquired loans totaled $0.2 million and contributed 1 basis point to loan yields during the three months ended March 31, 2017, and 2016. The increase in the net interest margin is the result of repricing interest-earning assets in a slightly higher rate environment offset by a comparable increase in funding costs.

The yield on interest-earning assets increased to 4.08% for the three months ended March 31, 2017 from 4.03% for the three months ended March 31, 2016. This increase is the result of slightly higher yields on commercial and equipment

financing loans, an increase in dividends from restricted equity securities, investment securities, and other short term investments, as well as an increase in prepayment penalties and late charges. During the three months ended March 31, 2017, the Company recorded $0.8 million in prepayment penalties and late charges, which contributed 5 basis points to yields on interest-earning assets in the three months ended March 31, 2017 compared to $0.6 million, or 4 basis points, for the three months ended March 31, 2016.

The overall cost of funds (including non-interest-bearing demand checking accounts) increased 1 basis point to 0.66% for the three months ended March 31, 2017 from 0.65% for the three months ended March 31, 2016. Refer to "Financial Condition - Borrowed Funds" above for more details.

Future net interest income, net interest spread and net interest margin may continue to be negatively affected by the low

interest-rate environment; ongoing pricing pressures in both loan and deposit portfolios; and the ability of the Company to

increase its core deposit ratio, increase its non-interest-bearing deposits as a percentage of total deposits, decrease its loan-to deposit ratio, or decrease its reliance on FHLBB advances. The Company maintains a slight asset sensitivity to the change in and level of interest rates. In general, higher overall average interest rates are beneficial to the Company and recent increases in the aggregate level of rates and the steepness of the rate curves are expected to have a positive effect on net interest income, net interest spread, and net interest margin. Net interest income may also be negatively affected by changes in the amount of accretion on acquired loans and leases, deposits and borrowed funds, which are included in interest income and interest expense, respectively.

Rate/Volume Analysis

The following table presents, on a tax-equivalent basis, the extent to which changes in interest rates and changes in volume of interest-earning assets and interest-bearing liabilities have affected the Company's interest income and interest expense during the periods indicated. Information is provided in each category with respect to: (i) changes attributable to changes in volume (changes in volume multiplied by prior rate), (ii) changes attributable to changes in rate (changes in rate multiplied by prior volume), and (iii) the net change. The changes attributable to the combined impact of volume and rate have been allocated proportionately to the changes due to volume and the changes due to rate.

Deposits

For the three months ended March 31, 2017, interest expense on deposits increased $0.3 million, or 7.1%, as compared to the same period in 2016. Interest expense increased $0.3 million due to an increase in interest rates and $14.0 thousand due to the growth in deposits. There was no purchase accounting accretion on acquired deposits for the three months ended March 31, 2017, compared to $24.0 thousand for the three months ended March 31, 2016. Purchase accounting accretion did not impact the Company's net interest margin for the three months ended March 31, 2017 and March 31, 2016.

Borrowed Funds

During the three months ended March 31, 2017, interest paid on borrowed funds increased $0.2 million, or 5.6% year over year, primarily driven by an increase in FHLBB borrowings. The cost of borrowed funds was 1.55% for the three months ended March 31, 2017 as compared to 1.58% for the three months ended March 31, 2016. This change was driven by an increase of $0.2 million in interest expense due to volume and by an increase of $34.0 thousand due to borrowing rates. For the three months ended March 31, 2017, the purchase accounting accretion on acquired borrowed funds was $0.5 million which contributed 3 basis points to the Company's net interest margin. This compared to $0.6 million and 4 basis points for the three months ended March 31, 2016.

For the three months ended March 31, 2017, the provision for credit losses increased $11.0 million, or 463.6%, to $13.4 million from $2.4 million for the three months ended March 31, 2016. The increase in the provision for credit losses for the

Table of Contents

three months ended March 31, 2017 was primarily driven by an increase in the provision due to the continued loan growth in the originated portfolios, an increase in specific reserves for taxi medallion loans as a result of a change in the underlying collateral value, the increase in the specific reserve of two commercial loans, the increase in historical loss factors applied to commercial loan portfolios including taxi medallion loans, and additional reserves required to cover net charge-offs. The increase was partially offset by a decrease in the provision related to improved credit characteristics and strong credit quality of the loan portfolios and a decrease in the provision for the acquired portfolios.

See management’s discussion of “Financial Condition — Allowance for Loan and Lease Losses” and Note 5, “Allowance for Loan and Lease Losses,” to the unaudited consolidated financial statements for a description of how management determined the allowance for loan and lease losses for each portfolio and class of loans.

Non-Interest Income

Total non-interest income	$	15,908	$	6,469	$	9,439		145.9	%

For the three months ended March 31, 2017, non-interest income increased $9.4 million, or 145.9%, to $15.9 million as compared to the same period in 2016. This increase is primarily due to an $11.4 million increase in gain on sales of investment securities, net, partially offset by $1.2 million decrease in loan level derivative income, and a $0.6 million decrease in gain on sales of loans and leases held-for-sale.

Loan level derivative income decreased $1.2 million, or 75.3%, to $0.4 million for the three months ended March 31, 2017 from $1.6 million for the same period of 2016, primarily driven by less loan level derivatives completed in the quarter.

Gain on sales of loans and leases held-for-sale decreased $0.6 million, or 61.0%, to $0.4 million for the three months ended March 31, 2017 from $0.9 million for the same period of 2016, primarily driven by a decrease in portfolio loan sales and residential loan sales.

Gain on sales of investment securities, net increased $11.4 million, or 100%, to $11.4 million for the three months ended March 31, 2017 from zero for the same period of 2016, primarily driven by the sale of NRS Stock.

Total non-interest expense	$	33,756	$	32,053	$	1,703		5.3	%

For the three months ended March 31, 2017, non-interest expense increased $1.7 million, or 5.3%, to $33.8 million as compared to the same period in 2016. This increase is primarily due to a $1.1 million increase in compensation and employee benefits expense, and a $0.3 million increase in equipment and data processing expense, and an increase of $0.2 million in other expense.

The efficiency ratio decreased to 48.92% for the three months ended March 31, 2017 from 57.57% for the three months ended March 31, 2016. Efforts to drive revenue growth contributed to the overall improvement in the efficiency ratio, along with an $11.4 million gain on sale of NRS Stock.

Compensation and employee benefits expense increased $1.1 million, or 5.6%, to $19.8 million for the three months ended March 31, 2017, from $18.7 million for the same period in 2016. This increase was primarily driven by an increase in employee headcount and incentive plan expenses.

Equipment and data processing expense increased $0.3 million, or 9.4%, to $4.1 million for the three months ended March 31, 2017 from $3.7 million for the same period in 2016. This increase was primarily driven by an increase related to core processing, software licenses, and IT consulting expense.

Other expense increased $0.2 million, or 7.6%, to $3.0 million for the three months ended March 31, 2017 from $2.7 million for the same period in 2016. This increase was primarily due to an increase in loan workout expense, offset by a decrease in debit and ATM losses.

Liquidity and Capital Resources

Liquidity

Liquidity is defined as the ability to meet current and future financial obligations of a short-term nature. The Company further defines liquidity as the ability to respond to the needs of depositors and borrowers, as well as to earnings enhancement opportunities, in a changing marketplace. Liquidity management is monitored by an Asset/Liability Committee ("ALCO"),

consisting of members of management, which is responsible for establishing and monitoring liquidity targets as well as strategies and tactics to meet these targets.

The primary source of funds for the payment of dividends and expenses by the Company is dividends paid to it by the Banks and Brookline Securities Corp. The primary sources of liquidity for the Banks consist of deposit inflows, loan repayments, borrowed funds, and maturing investment securities.

Deposits, which are considered the most stable source of liquidity, totaled $4.7 billion as of March 31, 2017 and represented 81.5% of total funding (the sum of total deposits and total borrowings), compared to deposits of $4.6 billion, or 81.5% of total funding, as of December 31, 2016. Core deposits, which consist of demand checking, NOW, savings and money market accounts, totaled $3.6 billion as of March 31, 2017 and represented 76.6% of total deposits, compared to core deposits of $3.6 billion, or 77.4% of total deposits, as of December 31, 2016. Additionally, the Company had $266.2 million of brokered deposits as of March 31, 2017, which represented 5.7% of total deposits, compared to $203.4 million or 4.4% of total deposits, as of December 31, 2016. The Company offers attractive interest rates based on market conditions to increase deposits balances, while managing cost of funds.

Borrowings are used to diversify the Company's funding mix and to support asset growth. When profitable lending and investment opportunities exist, access to borrowings provides a means to grow the balance sheet. Borrowings totaled $1.1 billion as of March 31, 2017, representing 18.5% of total funding, compared to $1.0 billion, or 18.5% of total funding, as of December 31, 2016.

As members of the FHLBB, the Banks have access to both short- and long-term borrowings. As of March 31, 2017, the Company's total borrowing limit from the FHLBB for advances and repurchase agreements was $1.4 billion as compared to $1.5 billion as of December 31, 2016, based on the level of qualifying collateral available for these borrowings.

As of March 31, 2017, the Banks also have access to funding through certain uncommitted lines of credit of $204.0 million. The Company had a $12.0 million committed line of credit for contingent liquidity as of March 31, 2017.

The Company has access to the Federal Reserve Bank "discount window" to supplement its liquidity. The Company has $42.4 million of borrowing capacity at the Federal Reserve Bank as of March 31, 2017. As of March 31, 2017, the Company did not have any borrowings with the Federal Reserve Bank outstanding.

Additionally, the Banks have access to liquidity through repurchase agreements and brokered deposits.

In general, the Company seeks to maintain a high degree of liquidity and targets cash, cash equivalents and investment securities available-for-sale balances of between 10% and 30% of total assets. As of March 31, 2017, cash, cash equivalents and investment securities available-for-sale totaled $591.2 million, or 9.1% of total assets. This compares to $591.3 million, or 9.2% of total assets as of December 31, 2016.

While management believes that the Company has adequate liquidity to meet its commitments, and to fund the Banks' lending and investment activities, the availabilities of these funding sources are subject to broad economic conditions and could be restricted in the future. Such restrictions would impact the Company's immediate liquidity and/or additional liquidity needs.

Off-Balance-Sheet Financial Instruments

The Company is party to off-balance-sheet financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby and commercial letters of credit and interest-rate swaps. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received.

The contract amounts reflect the extent of the involvement the Company has in particular classes of these instruments. Such commitments involve, to varying degrees, elements of credit risk and interest-rate risk in excess of the amount recognized in the consolidated balance sheet. The Company’s exposure to credit loss in the event of non-performance by the counterparty is represented by the contractual amount of the instruments. The Company uses the same policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market Risk

Market risk is the risk that the market value or estimated fair value of the Company's assets, liabilities, and derivative financial instruments will decline as a result of changes in interest rates or financial market volatility, or that the Company's net income will be significantly reduced by interest-rate changes.

Interest-Rate Risk

The principal market risk facing the Company is interest-rate risk, which can occur in a variety of forms, including repricing risk, yield-curve risk, basis risk, and prepayment risk. Repricing risk occurs when the change in the average yield of either interest-earning assets or interest-bearing liabilities is more sensitive than the other to changes in market interest rates. Such a change in sensitivity could reflect a number of possible mismatches in the repricing opportunities of the Company's assets and liabilities. Yield-curve risk reflects the possibility that changes in the shape of the yield curve could have different effects on the Company's assets and liabilities. Basis risk occurs when different parts of the balance sheet are subject to varying base rates reflecting the possibility that the spread from those base rates will deviate. Prepayment risk is associated with financial instruments with an option to prepay before the stated maturity, often a disadvantage to person selling the option; this risk is most often associated with the prepayment of loans, callable investments, and callable borrowings.

Asset/Liability Management

Market risk and interest-rate risk management is governed by the Company's Asset/Liability Committee ("ALCO"). The ALCO establishes exposure limits that define the Company's tolerance for interest-rate risk. The ALCO and the Company's Treasury Group measure and manage the composition of the balance sheet over a range of possible changes in interest rates while remaining responsive to market demand for loan and deposit products. The ALCO monitors current exposures versus limits and reports those results to the Board of Directors. The policy limits and guidelines serve as benchmarks for measuring interest-rate risk and for providing a framework for evaluation and interest-rate risk-management decision-making. The Company measures its interest-rate risk by using an asset/liability simulation model. The model considers several factors to determine the Company's potential exposure to interest-rate risk, including measurement of repricing gaps, duration, convexity, value-at-risk, market value of portfolio equity under assumed changes in the level of interest rates, the shape of yield curves, and general market volatility.

Management controls the Company's interest-rate exposure using several strategies, which include adjusting the maturities of securities in the Company's investment portfolio, limiting or expanding the terms of loans originated, limiting fixed-rate deposits with terms of more than five years, and adjusting maturities of FHLBB advances. The Company limits this risk by restricting the types of MBSs it invests in to those with limited average life changes under certain interest-rate-shock scenarios, or securities with embedded prepayment penalties. The Company also places limits on holdings of fixed-rate mortgage loans with maturities greater than five years. The Company may also use derivative instruments, principally interest-rate swaps, to manage its interest-rate risk; however, the Company had no derivative fair value hedges or derivative cash flows hedges as of March 31, 2017 or December 31, 2016. See Note 8, “Derivatives and Hedging Activities,” to the unaudited consolidated financial statements.

Measuring Interest-Rate Risk

As noted above, interest-rate risk can be measured by analyzing the extent to which the repricing of assets and liabilities are mismatched to create an interest-rate sensitivity gap. An asset or liability is said to be interest-rate sensitive within a specific period if it will mature or reprice within that period. The interest-rate sensitivity gap is defined as the difference between the amount of interest-earning assets maturing or repricing within a specific time period and the amount of interest-bearing liabilities maturing or repricing within that same time period. A gap is considered positive when the amount of interest-rate-sensitive assets exceeds the amount of interest-rate-sensitive liabilities. A gap is considered negative when the amount of interest-rate-sensitive liabilities exceeds the amount of interest-rate-sensitive assets. During a period of falling interest rates, therefore, a positive gap would tend to adversely affect net interest income. Conversely, during a period of rising interest rates, a positive gap position would tend to result in an increase in net interest income.

The Company's interest-rate risk position is measured using both income simulation and interest-rate sensitivity "gap" analysis. Income simulation is the primary tool for measuring the interest-rate risk inherent in the Company's balance sheet at a given point in time by showing the effect on net interest income, over a twelve-month period, of a variety of interest-rate shocks. These simulations take into account repricing, maturity, and prepayment characteristics of individual products. The ALCO reviews simulation results to determine whether exposure resulting from changes in market interest rates remains within

established tolerance levels over a twelve-month horizon, and develops appropriate strategies to manage this exposure. The Company's interest-rate risk analysis remains modestly asset-sensitive as of March 31, 2017.

The assumptions used in the Company’s interest-rate sensitivity simulation discussed above are inherently uncertain and, as a result, the simulations cannot precisely measure net interest income or precisely predict the impact of changes in interest rates.

As of March 31, 2017, net interest income simulation indicated that the Company's exposure to changing interest rates was within tolerance. The ALCO reviews the methodology utilized for calculating interest-rate risk exposure and may periodically adopt modifications to this methodology. The following table presents the estimated impact of interest-rate changes on the Company's estimated net interest income over the twelve-month periods indicated:



	Estimated Exposure to Net Interest Income over Twelve-Month Horizon Beginning
	March 31, 2017					December 31, 2016
Gradual Change in Interest Rate Levels	Dollar Change			Percent Change		Dollar Change			Percent Change
	(Dollars in Thousands)
Up 300 basis points	$	5,611		2.6	%	$	6,403		3.0	%
Up 200 basis points	3,832			1.7	%	4,420			2.1	%
Up 100 basis points	1,935			0.9	%	2,288			1.1	%
Down 100 basis points	(5,397		)	-2.5	%	(5,196		)	-2.5	%

The estimated impact of a 300 basis point increase in market interest rates on the Company's estimated net interest income over a twelve-month horizon was a positive 2.6% as of March 31, 2017, compared to a positive 3.0% as of December 31, 2016, the decrease in asset sensitivity was due to a change in the funding mix, as wholesale funding replaced core deposits and funded balance sheet growth.

The Company also uses interest-rate sensitivity “gap” analysis to provide a more general overview of its interest-rate risk profile. The interest-rate sensitivity gap is defined as the difference between interest-earning assets and interest-bearing

liabilities maturing or repricing within a given time period. At March 31, 2017, the Company’s one-year cumulative gap was a negative $395.5 million, or 6.46% of total interest-earning assets, compared with a negative $275.3 million, or 4.56% of total interest-earning assets, at December 31, 2016.

The assumptions used in the Company's interest-rate sensitivity simulation discussed above are inherently uncertain and, as a result, the simulations cannot precisely measure net interest income or precisely predict the impact of changes in interest rates. For additional discussion on interest-rate risk see Item 7A, “Quantitative and Qualitative Disclosures about Market Risk” of the Company’s 2016 Annual Report on Form 10-K.

Economic Value of Equity ("EVE") at Risk Simulation is conducted in tandem with net interest income simulations to ascertain a longer term view of the Company’s interest-rate risk position by capturing longer-term repricing risk and options risk embedded in the balance sheet. It measures the sensitivity of the economic value of equity to changes in interest rates. The EVE at Risk Simulation values only the current balance sheet and does not incorporate growth assumptions. As with the net interest income simulation, this simulation captures product characteristics such as loan resets, repricing terms, maturity dates, and rate caps and floors. Key assumptions include loan prepayment speeds, deposit pricing elasticity, and non-maturity deposit attrition rates. These assumptions can have significant impacts on valuation results as the assumptions remain in effect for the entire life of each asset and liability. The Company conducts non-maturity deposit behavior studies on a periodic basis to support deposit assumptions used in the valuation process. All key assumptions are subject to a periodic review.

EVE at Risk is calculated by estimating the net present value of all future cash flows from existing assets and liabilities using current interest rates as well as parallel shocks to the current interest-rate environment. The following table sets forth the estimated percentage change in the Company’s EVE at Risk, assuming various shifts in interest rates. Given the interest rate environment as of March 31, 2017, simulations for interest rate declines of more than 100 basis points were not deemed to be meaningful.

	Estimated Percent Change in Economic Value of Equity
Parallel Shock in Interest Rate Levels	At March 31, 2017		At December 31, 2016
Up 300 basis points	-2.0	%	-4.6	%
Up 200 basis points	-1.7	%	-4.4	%
Up 100 basis points	-0.5	%	-1.6	%
Down 100 basis points	-7.1	%	-6.4	%

The Company's EVE sensitivity for Up shock scenarios decreased from 2016 primarily driven by a reduction in the duration of assets due to accelerating prepayments and lower rates.

Controls and Procedures

Under the supervision and with the participation of the Company’s Management, including the Company’s Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), the Company has evaluated the effectiveness of its disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer considered that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is (i) recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to the Company’s Management, including its Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

There has been no change in the Company’s internal control over financial reporting identified in connection with the quarterly evaluation that occurred during the Company’s last fiscal quarter that has materially and detrimentally affected, or is reasonably likely to materially and detrimentally affect, the Company’s internal controls over financial reporting.

The Company’s Management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a -15(f). The Company’s internal control system was designed to provide reasonable assurance to its Management and the Board of Directors regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. The Company’s Management assessed the effectiveness of its internal control over financial reporting as of the end of the period covered by this report.

Management’s Report on Internal Control Over Financial Reporting as of December 31, 2016 and the related Report of Independent Registered Public Accounting Firm thereon appear on pages F-1 and F-2 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.
