Notes to Unaudited Consolidated Financial Statements

At and for the Three Months Ended March 31, 2013 and 2012

(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 bank; and First Ipswich Bank (“First Ipswich” and formerly known as the First National Bank of 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 individual customers through its banks and non-bank subsidiaries.

Brookline Bank, which includes its wholly-owned subsidiaries BBS Investment Corp. and Longwood Securities Corp., and its 84.8%-owned subsidiary, Eastern Funding LLC (“Eastern Funding”), operates 22 full-service banking offices in Brookline, Massachusetts and the greater Boston metropolitan area. BankRI, which includes its wholly-owned subsidiaries BRI Investment Corp., Macrolease Corporation (“Macrolease”), Acorn Insurance Agency and BRI Realty Corp., operates 18 full-service banking offices in Providence County, Kent County and Washington County, Rhode Island. First Ipswich, which includes its wholly-owned subsidiaries First Ipswich Securities II Corp., First Ipswich Insurance Agency, First Ipswich Realty and FNBI Realty, operates six full-service banking offices on the north shore of eastern Massachusetts and in the Boston metropolitan area.

The Company’s activities include acceptance of commercial business 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, origination of indirect automobile loans, 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, 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 member banks, 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. 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 for all three Banks. As FDIC-insured depository institutions, all three 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 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, 2012.

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

At and for the Three Months Ended March 31, 2013 and 2012

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, the review of goodwill and intangibles for impairment, income tax accounting and status of contingencies.

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 February 2013, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. This ASU clarifies the scope of offsetting disclosure requirements in ASU 2011-11, Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities. Under ASU 2013-01, the disclosure requirements would apply to derivative instruments accounted for in accordance with ASC 815, including bifurcated embedded derivatives, repurchase agreements and reverse repurchase agreements, and securities borrowing and securities lending arrangements that are either offset on the balance sheet or subject to an enforceable master netting arrangement or similar agreement. Entities with other types of financial assets and financial liabilities subject to a master netting arrangement or similar agreement also are affected because these amendments make them no longer subject to the disclosure requirements in ASU No. 2011-11. Effective January 1, 2013, companies are required to disclose (a) gross amounts of recognized assets and liabilities; (b) gross amounts offset in the statement of financial position; (c) net amounts of assets and liabilities presented in the statement of financial position; (d) gross amount subject to enforceable master netting agreement not offset in the statements of financial position; and (e) net amounts after deducting (d) from (c). The disclosure should be presented in tabular format (unless another format is more appropriate) separately for assets and liabilities. The intent of the new disclosure is to enable users of financial statements to understand the effect of those arrangements on its financial position and to allow investors to better compare financial statements prepared under GAAP with financial statements prepared under International Financial Reporting Standards. As required, the Company added relevant disclosure in Note 8, “Derivatives and Hedging Activities.”

In February 2013, the FASB issued ASU No. 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income. This ASU states that the amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. The amendments do, however, require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required to be reclassified in their entirety to net income under U.S. GAAP, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The amendments are effective prospectively for reporting periods beginning after December 15, 2012. In response to this ASU, the Company added a new footnote to disclose the amounts reclassified out of accumulated other comprehensive income and the effects on the line items of net income.

The Company performs regular analysis on the available-for-sale investment securities portfolio to determine whether a decline in fair value indicates that an investment is other-than-temporarily-impaired (“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 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 security before recovery of its amortized cost, the credit portion of the impairment loss is recognized in earnings 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 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 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 earnings.

Debt Securities

The Company expects to recover its amortized cost basis on all debt securities in its available-for-sale and held-to-maturity portfolios. Furthermore, the Company does not intend to sell nor does it anticipate that it will be required to sell any of its securities in an unrealized loss position at March 31, 2013, prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions as well as its historically low portfolio turnover.

U.S. Government-Sponsored Enterprises

The Company invests in securities issued by of U.S. Government-sponsored enterprises (“GSEs”), including GSE debt securities, 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 (“Freddie Mac”), the Government National Mortgage Association (“GNMA”), the Federal Home Loan Banks and the Federal Farm Credit Bank. At March 31, 2103, none of those obligations is

backed by the full faith and credit of the U.S. Government, except for GNMA MBSs and CMOs, and Small Business Administration (“SBA”) commercial loan asset-backed securities with an estimated fair value of $14.6 million.

At March 31, 2013, the Company held GSE debentures with a total fair value of $56.6 million and a net unrealized gain of $0.2 million. At December 31, 2012, the Company held GSE debentures of with a total fair value of $69.8 million and a net unrealized gain of $0.3 million.

At March 31, 2013, the Company held GSE mortgage-related securities with a total fair value of $406.2 million and a net unrealized gain of $2.8 million. During the three months ended March 31, 2013, the Company purchased a total of $40.0 million in GSE CMOs and GSE MBSs to reinvest matured cash flow.

Private-Label CMOs

At March 31, 2013, the Company held private-issuer CMO-related securities with a total fair value of $5.8 million and a net unrealized gain of $0.2 million. At December 31, 2012, the Company held private issuer CMO-related securities with a total fair value of $6.9 million and a net unrealized gain of $0.1 million.

Auction-Rate Municipal Obligations and Municipal Obligations

The auction-rate obligations owned by the Company were rated “AAA” at the time of acquisition due, in part, to the guarantee of third-party insurers who would have to pay the obligations if the issuers failed to pay the obligations when they become due. During the financial crisis, certain third-party insurers experienced financial difficulties and were not able to meet their contractual obligations. As a result, auctions failed to attract a sufficient number of investors and created a liquidity problem for those investors who were relying on the obligations to be redeemed at auction. Since then, there has not been an active market for auction-rate municipal obligations.

Based on an evaluation of market factors, the estimated fair value of the auction-rate municipal obligations owned by the Company at March 31, 2013 was $2.0 million, with a corresponding net unrealized loss of $0.1 million. Full collection of the obligations is expected because the financial condition of the issuers is sound, none of the issuers has 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 unrealized losses.

The Company owns municipal obligations with an estimated fair value of $1.1 million which approximated amortized cost at March 31, 2013. Full collection of the obligations is expected because the financial condition of the issuers is sound, none of the issuers has 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 unrealized losses.

Corporate Obligations

From time to time, the Company will invest in high-quality corporate obligations to provide portfolio diversification and improve the overall yield on the portfolio. The Company owned five corporate obligation securities with a total fair value of $10.8 million and total net unrealized gains of $0.3 million at March 31, 2013. All but one of the securities are investment grade. This non-investment-grade security is currently in an unrealized gain position.

Trust Preferred Securities and Trust Preferred Pools

The Company’s portfolio of trust preferred securities at March 31, 2013 includes two trust preferred pools (“PreTSLs”) which the Company has designated “PreTSL B” and “PreTSL C.” The Company monitors these pools closely for impairment due to a history of defaults experienced on the part of the banks underlying the trust preferred securities. The following tables summarize the pertinent information at March 31, 2013 that was considered in determining whether OTTI existed on these PreTSLs:

	At March 31, 2013
	Class	Deferrals/ Defaults/ Losses to Date (1)		Estimated Total Remaining Projected Defaults (2)		Estimated Excess Subordination (3)		Lowest Credit Rating to Date (4)	Current Credit Rating (5)

PreTSL B	A-1	26	%	15	%	43	%	CCC	B
PreTSL C	Mezzanine	43	%	21	%	0	%	C	CC

(1) As a percentage of original collateral.

(2) As a percentage of performing collateral.

(3) Excess subordination represents the additional defaults/losses in excess of both current and projected defaults/losses that the security can absorb before the security is exposed to a loss in principal, after taking into account the best estimate of future deferrals/defaults/losses.

(4) Lower of S&P and Moody’s.

(5) The Company reviewed credit ratings provided by S&P and Moody’s in 2012 in its evaluation of issuers.

	At March 31, 2013
					Gross					Total Cumulative OTTI
			Amortized		Unrealized					Credit-		Credit and
	Current Par		Cost (1)		Gain/(Loss)			Fair Value		Related		Non-Credit
	(In Thousands)

PreTSL B	830		825		(125		)	700		—		—
PreTSL C	787		4		177			181		—		—
Total	$	1,617	$	829	$	52		$	881	$	—	$	—

(1) The amortized cost reflects previously recorded credit-related OTTI charges recognized in earnings for the applicable securities as well as the fair value adjustment recorded on PreTSL C in connection with purchase accounting.

In performing the analysis for OTTI impairment on the PreTSLs, expected future cash flow scenarios for each pool were considered under varying levels of severity for assumptions including future delinquencies, recoveries and prepayments. The Company also considered its relative seniority within the pools and any excess subordination. The Company’s OTTI assessment for the three months ended March 31, 2013 was as follows:

PreTSL B — PreTSL B has experienced $91.0 million in deferrals/defaults, or 26.0% of the security’s underlying collateral, to date. During the first quarter of 2013, there was no change in the deferral or default schedules and no further rating actions. Based on the security’s future expected cash flows and after factoring in projected defaults of 15.0% over its remaining life, the security’s current amortized cost (99.4% of current par), $110.0 million in excess subordination (43.0% of outstanding performing collateral) and the Bank’s intent and ability to hold the security until recovery, Management believes that no OTTI charges are warranted at this time.

PreTSL C — PreTSL C was acquired on January 1, 2012 as part of Brookline Bancorp’s acquisition of Bancorp Rhode Island, Inc. PreTSL C has experienced $59.0 million in deferrals/defaults, or 43.0% of the security’s underlying collateral, to date. During the first quarter of 2013, there were $10.0 million less deferrals/defaults scheduled, but no further rating actions. Based on the security’s future expected cash flows and after factoring in projected defaults of 21.0% over its remaining life, the security’s current amortized cost (0.5% of current par) and the Bank’s intent and ability to hold the security until recovery, management believes that no OTTI charges are warranted at this time.

Actual maturities of GSE debt securities may differ from those presented above since certain obligations provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty. At March 31, 2013, issuers of debt securities with an estimated fair value of approximately $8.9 million had the right to call or prepay the obligations, the scheduled maturities of which were $4.8 million after one year through five years, $0.2 million after five years though ten years and $3.9 million after ten years. MBSs and CMOs are included above based on their contractual maturities; the remaining lives, however, are expected to be shorter due to anticipated prepayments.

Security Sales

There were no sales of investment securities during either of the three-month periods ended March 31, 2013 or 2012.

Subsequent to acquisition, management periodically reforecasts the expected cash flows for acquired ASC 310-30 loans, taking into account prepayment speeds, probability of default and loss given defaults. Management then compares this reforecast to the original estimates to evaluate the need for a loan loss provision and/or prospective yield adjustments. During the three months ended March 31, 2013, accretable yield adjustments totaling $2.4 million 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. No accretable yield adjustments were made in the acquired loan portfolio during the three months ended March 31, 2012.

The aggregate remaining nonaccretable difference (representing both principal and interest) applicable to acquired loans totaled $12.4 and $13.0 million at March 31, 2013 and December 31, 2012, respectively.

Related Party Loans

The Banks’ authority to extend credit to their respective directors and executive officers, as well as to entities controlled by such persons, is currently governed by the requirements of the Sarbanes-Oxley Act of 2002 and Regulation O of the FRB. Among other things, these provisions require that extensions of credit to insiders (1) be made on terms that are substantially the same as, and follow credit underwriting procedures that are not less stringent than, those prevailing for comparable transactions with unaffiliated persons and that do not involve more than the normal risk of repayment or present other unfavorable features; and (2) not exceed certain limitations on the amount of credit extended to such persons, individually and in the aggregate, which limits are based, in part, on the amount of the Banks’ capital. In addition, the extensions of credit to insiders must be approved by each Bank’s Board of Directors.

The following table summarizes the change in the total amounts of loans and advances, to directors, executive officers and their affiliates for the periods indicated. All loans were performing at March 31, 2013.

	Three Months Ended March 31,
	2013			2012

Balance at end of period	$	4,813		$	5,949

Unfunded commitments on extensions of credit to insiders totaled $7.6 million at March 31, 2013.

Recourse Obligations

As a result of the acquisition of BankRI, the Company has a recourse obligation under a lease sale agreement for up to 8.0% of the original sold balance of approximately $9.8 million. Historically, delinquency rates for the lease portfolio have been significantly less than 8.0%; the rate at March 31, 2013 was 0.25%.

Procedure for Placing Loans and Leases on Nonaccrual

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 performance has been achieved.

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. 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 pools: (1) commercial real estate loans, (2) commercial loans and leases, (3) indirect automobile loans and (4) 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 mortgage loans, multi-family mortgage loans and construction loans. Commercial loans and leases are divided into three classes: commercial loans, equipment financing, and loans to condominium associations. The indirect automobile loan segment is not divided into classes. Consumer loans are divided into three classes: residential mortgage loans, home equity loans and other consumer loans. 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.

General Allowance

The general allowance for loan and lease losses was $38.3 million at March 31, 2013, compared to $36.8 million at December 31, 2012. The general portion of the allowance for loan and lease losses decreased by $1.5 million during the three months ended March 31, 2013, in part as a result of the decline in indirect automobile loan balances.

Specific Allowance

The specific allowance for loan and lease losses was $1.5 million at March 31, 2013, compared to $1.7 million at December 31, 2012. The specific allowance decreased by $0.2 million during the three months ended March 31, 2013, largely as a result of a large commercial loan payoff, offset by specific reserves on the equipment financing portfolio.

Unallocated Allowance

The unallocated allowance for loan and lease losses was $2.7 million at March 31, 2013, compared to $2.6 million at December 31, 2012. The unallocated portion of the allowance for loan and lease losses increased by $0.1 million during the three months ended March 31, 2013, largely as a result of a change in the mix of the loan portfolio.

Credit Quality Assessment

At the time of loan origination, a rating is assigned based on the financial strength of the borrower and the value of assets pledged as collateral. The Company continually monitors the asset 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 (“TDR”).

The Company reviews numerous credit quality indicators when assessing the risk in its loan portfolio. For the commercial real estate mortgage, multi-family mortgage, construction, commercial, equipment financing, condominium association and other consumer loan and lease classes, 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 of the commercial real estate and commercial loan portfolios. The results of these reviews are reported to the Board of Directors. For the indirect automobile portfolio, the Company primarily uses borrower FICO scores for monitoring credit risk while for residential mortgage and home equity portfolios loan-to-value ratios are used as the primary credit quality indicator.

The ratings categories used for assessing credit risk in the commercial real estate mortgage, 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 Asset 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 Bank’s asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned.

Notes to Unaudited Consolidated Financial Statements

At and for the Three Months Ended March 31, 2013 and 2012

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.

Commercial Real Estate Loans — At March 31, 2013, loans outstanding in the three classes within this category expressed as a percentage of total loans and leases outstanding (including deferred loan origination costs) were as follows: commercial real estate mortgage loans — 31.1%; multi-family mortgage loans — 14.0%; 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 from the past five years. Management has accumulated information on actual loan charge-offs and recoveries by class covering, depending on loan/lease category, up to 28 years of loss history. The Company has a long history of low frequency of loss in this loan class. As a result, determination of loss factors is based on considerable judgment by management, including evaluation of the risk characteristics related to current internal and external factors. Notable risk characteristics related to the commercial real estate mortgage and multi-family mortgage portfolios are the concentration in those classes of

outstanding loans within the greater Boston and Providence metropolitan areas and the effect the local economies could have on the collectability of those loans. While unemployment in the greater Boston metropolitan area is not as high as in other parts of the United States, it is nonetheless elevated in relation to historic trends. Unemployment in Rhode Island remains high relative to other parts of the United States. Should unemployment in the greater Boston and/or Providence metropolitan areas remain elevated, the resulting negative consequences could affect occupancy rates in the properties financed by the Company and cause certain borrowers to be unable to service their debt obligations.

Other factors taken into consideration in establishing the allowance for loan and lease losses for this class were the rate of growth of originated loans, the decrease in originated loans delinquent over 30 days from $8.6 million (0.6% of originated commercial real estate loans outstanding including deferred loan origination costs) at December 31, 2012 to $6.2 million (0.4%) at March 31, 2013 and the decrease in originated criticized loans from $8.8 million at December 31, 2012 to $7.5 million at March 31, 2013. The Company also takes into consideration the impact that the economy, and in particular the housing market, has on the rents and values associated with its apartment and multi-family mortgage loans. The increase in renters versus homeowners has increased multi-family rents. This trend, coupled with historically low capitalization rates, has increased apartment and multi-family property valuations, which, in turn, has increased the number of multi-family properties under development. These increases in multi-family rents and valuations could drop if the demand for rentable housing declines or interest rates rise. For further discussion of criticized loans, see “Credit Quality Assessment” section above.

While the Company’s construction loan portfolio is small, there are higher risks associated with such loans. The source of repayment for the majority of the construction loans is derived from the sale of constructed housing units. These risk factors are considered when estimating allowances for loan losses for this asset class. A project that is viable at the outset can experience losses when there is a drop in the demand for housing units. Typically, the level of loss in relation to the amount loaned is high when construction projects run into difficulty.

Commercial Loans and Leases — At March 31, 2013, loans and leases outstanding in the three classes within this portfolio expressed as a percent of total loans and leases outstanding (including deferred loan origination costs), were as follows: commercial loans and leases — 9.6%; equipment financing loans — 10.7%; and loans to condominium associations — 1.0%.

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. The factors applied are based on historic loan and lease loss experience and on an assessment of internal and external factors. Management has accumulated information on actual loan and lease charge-offs and recoveries by class covering 19 years for commercial loans and leases, six years for equipment financing loans and leases, and twelve years for loans to condominium associations. Commercial loan and lease losses generally have been infrequent and modest while no losses have been experienced from loans to condominium associations since the Company started originating such loans. The risk characteristics described in “Commercial Real Estate Loans” above regarding concentration of outstanding loans within the greater Boston and Providence metropolitan areas and the status of the local economies are also applicable to the commercial and condominium association loan classes. Until the economy improves sufficiently, some commercial loan borrowers may have difficulty generating sufficient profitability and liquidity to service their debt obligations.

The Company’s equipment financing loans and leases are concentrated in the financing of coin-operated laundry, dry cleaning, fitness and convenience store equipment, and, most recently, tow trucks. A significant share (39.8%) of the Company’s equipment financing business is conducted in the states of New York and New Jersey, with the balance in other locations throughout the United States. The loans and leases are considered to be of higher risk because the borrowers are typically small-business owners who operate with limited financial resources and are more likely to experience difficulties in meeting their debt obligations when the economy is weak or unforeseen adverse events arise. Among the factors taken into consideration in establishing the allowance for loan and lease losses for the equipment financing category were the rate of growth of originated loans and leases outstanding, the entrée into tow-truck lending, the decrease in originated loans and leases delinquent over 30 days from $5.6 million (1.5% of originated equipment financing loans and leases outstanding including deferred loan origination costs) at

December 31, 2012 to $4.1 million (1.0%) at March 31, 2013, and the decrease in total criticized originated loans and leases from $7.2 million at December 31, 2012 to $5.6 million at March 31, 2013.

Regarding loans to condominium associations, loan proceeds are generally used for capital improvements and loan payments are generally derived from ongoing association dues or special assessments. While the loans are unsecured, associations are permitted statutory liens on condominium units when owners do not pay their dues or special assessments. Proceeds from the subsequent sale of an owner unit can sometimes be a source for payment of delinquent dues and assessments. Sales prices and the volume of sales of condominium units have remained depressed over the last two years. Accordingly, the risk of loss from loans to condominium associations has increased. These factors have been considered in determining the amount of allowance for loan and lease losses established for this loan class.

Indirect Automobile Loans — At March 31, 2013, indirect automobile loans represented 12.2% of the Company’s total loan and lease portfolio (including deferred loan origination costs). Determination of the allowance for loan and lease losses for this portfolio is based primarily on borrowers’ credit scores (generally considered to be a good indicator of capacity to pay a loan, with the risk of loan loss increasing as credit scores decrease), and on an assessment of trends in loan underwriting, loan loss experience, and the economy and industry conditions. Data are gathered on loan originations by year broken down into the following ranges of borrower credit scores: over 700, between 661 and 700, and 660 and below. The Company’s loan policy specifies underwriting guidelines based in part on the score of the borrower and includes ceilings on the percent of loans originated that can be to borrowers with credit scores of 660 and below. The breakdown of the amounts shown in “Credit Quality Information” below is based on borrower credit scores at the time of loan origination. Due to the weakened economy, it is possible that the credit scores of certain borrowers may have deteriorated since the time the loan was originated. Additionally, migrations of loan charge-offs and recoveries are analyzed by year of origination. Based on that data and taking into consideration other factors such as loan delinquencies and economic conditions, projections are made as to the amount of expected losses inherent in the portfolio. The percentage of loans made to borrowers with credit scores of 660 and below was 3.2% and 3.1% at March 31, 2013 and December 31, 2012, respectively.

Consumer Loans — At March 31, 2013, loans outstanding within the three classes within this portfolio expressed as a percent of total loans and leases outstanding (including deferred loan origination costs) were as follows: residential mortgage loans — 12.2%; home equity loans — 6.1%; and other consumer loans — 0.2%.

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 and the economic conditions in those areas as previously commented upon in the “Commercial Real Estate Loans” subsection above. The loan-to-value ratio is 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. The loan-to-value ratios for residential mortgage loans are based on loan balances outstanding at March 31, 2013 and December 31, 2012 expressed as a percent of appraised real estate values at the time of loan origination. The loan-to-value ratios for home equity loans outstanding at March 31, 2013 and December 31, 2012 are based on the maximum amount of credit available to a borrower plus the balance of other loans secured by the same real estate serving as collateral for the home equity loan at the time the line of credit was established expressed as a percent of the appraised value of the real estate at the time the line of credit was established. 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. For non-impaired loans, loss factors are applied to loans outstanding for each class. The factors applied are based primarily on historic loan loss experience, the value of underlying collateral, underwriting standards, and trends in loan-to-value ratios, credit scores of borrowers, sales activity, selling prices, geographic concentrations and employment conditions.

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 exposure to loss is not considered to be high due to the combination of current property values, the low level of losses experienced in the past few years and the low level of loan delinquencies at March 31, 2013. If the local economy weakens, however, a rise in losses in those loan classes could occur. Historically, losses in these classes have been low.

Impaired Loans and Leases

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.

(7) Comprehensive Income

Comprehensive income represents the sum of net income (loss) and other comprehensive income (loss). For the three months ended March 31, 2013 and March 31, 2012, the Company’s other comprehensive income include 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 by component, net of tax, were as follows for the periods indicated:

	Three Months Ended March 31, 2013
	Investment Securities Available-for- Sale			Postretirement Benefits		Accumulated Other Comprehensive Income

The Company did not reclassify any amounts out of accumulated other comprehensive income for the three months ended March 31, 2013.

(8) Derivatives and Hedging Activities

The Company may use interest-rate contracts (swaps, caps and floors) as part of interest-rate risk management strategy. 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 at March 31, 2013 or December 31, 2012.

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 interest-rate swaps 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 swaps associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. At March 31, 2013, the Company had eight interest-rate swaps with an aggregate notional amount of $23.0 million related to this program, compared to ten interest-rate swaps with an aggregate notional amount of $33.2 million at December 31, 2012.

The table below presents the fair value and classification of the Company’s derivative financial instruments on the unaudited consolidated balance sheets at March 31, 2013, and the effect of the Company’s derivative financial instruments on the unaudited consolidated income statements for the three months ended March 31, 2013:

	At March 31, 2013					Three Months Ended March 31, 2013
	Asset Derivatives		Liability Derivatives			Gain Recognized in Income on Derivatives (1)
	(In Thousands)
Total derivatives (interest-rate products) not designated as hedging instruments	$	1,208	$	(1,269	)	$	(2	)

(1) The amount of gain recognized in income on derivatives represents changes related to the fair value of the interest rate products.

Certain of the derivative agreements contain provisions that require the Company to post collateral if the derivative exposure exceeds a threshold amount. The Company has posted collateral of $0.6 million and $0.5 million in the normal course of business at March 31, 2013 and December 31, 2012, respectively.

Investment Securities Available-for-Sale

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 that 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, and GSE residential MBSs and CMOs, all of which are included in Level 2. Certain fair values are estimated using pricing models (such as trust preferred securities and auction-rate municipal securities) and are included in Level 3.

Interest-Rate Swaps

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. The change in value of interest-rate swap assets and liabilities attributable to credit risk was not significant during the reported periods. See also Note 8, “Derivatives and Hedging Activities.”

The table below presents quantitative information about significant unobservable inputs (Level 3) for assets measured at fair value on a recurring basis at March 31, 2013.

	$	—	$	38,240	$	—	$	38,240

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 other real estate owned 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 vehicles and repossessed equipment are carried at estimated fair value less costs to sell based on auction pricing (Level 2).

Summary of Estimated Fair Values of Financial Instruments

The following table presents the carrying amount, estimated fair value, and placement in the fair value hierarchy of the Company’s financial instruments at the dates indicated. This table excludes financial instruments for which the carrying amount approximates fair value. Financial assets for which the fair value approximates carrying value include cash and cash equivalents, FHLBB and FRB stock and accrued interest receivable. Financial liabilities for which the fair value approximates carrying value include non-maturity deposits, short-term borrowings and accrued interest payable.

Investment Securities Held-to-Maturity

The fair values of investment securities held-to-maturity are estimated using pricing models or are based on comparisons to market prices of similar securities and are considered to be Level 3.

Loans and Leases

The fair values of performing loans and leases were 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, indirect automobile, residential mortgage, home equity and other consumer. These categories were further disaggregated based on 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.

Loans Held for Sale

Residential mortgage loans held for sale are recorded at the lower of cost or fair value and are therefore measured at fair value on a non-recurring basis. When available observable inputs are used as secondary market data, including pricing on recent closed market transactions for loans with similar characteristics. Accordingly, such loans are classified as Level 2 measurements.

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).

At and for the Three Months Ended March 31, 2013 and 2012

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.

(11) Income Taxes

The Company recorded income tax expense of $5.1 million for the first three months of 2013, compared to $4.9 million for the first three months of 2012, representing total effective tax rates of 35.7% and 42.5%, respectively. The decrease in tax rate to 35.7% for the three months ended March 31, 2013 is primarily due to recognition of $1.6 million of projected affordable housing tax credits for the year 2013, compared to $0.2 million in the three months ended March 31, 2012, and the non-deductibility of $1.4 million in the first quarter of 2012 of the $5.4 million in professional fees incurred related to the BankRI acquisition. Additional state taxes were also recognized in the first quarter of 2012 as the projected state tax savings from the acquisition of BankRI reduced the value of the deferred tax asset by $0.5 million, increasing the tax expense in 2012.

(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 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.

Performance standby letters of credit	2,916		2,916
Commercial and similar letters of credit	25		112
Back-to-back interest-rate swaps	23,021		33,221

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, included in other liabilities, was $0.8 million at March 31, 2013 and $0.7 million at December 31, 2012.

From time to time the Company enters into back-to-back interest-rate swaps with commercial customers and third-party financial institutions. These swaps allow the Company to offer long-term fixed-rate commercial loans while mitigating the interest-rate risk of holding those loans. In a back-to-back interest-rate swap transaction, the Company lends to a commercial customer on a floating-rate basis and then enters into an interest-rate swap 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.

Forward-Looking Statements

Certain statements contained in this Quarterly Report on Form 10-Q that are not historical facts may constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements involve risks and uncertainties. These statements, which are based on certain assumptions and describe Brookline Bancorp, Inc.’s (the “Company’s”) future plans, strategies and expectations, can generally be identified by the use of the words “may,” “will,” “should,” “could,” “would,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target” and similar expressions. These statements include, among others, statements regarding the Company’s intent, belief or expectations with respect to economic conditions, trends affecting the Company’s financial condition or results of operations, and the Company’s exposure to market, liquidity, interest-rate and credit risk.

Forward-looking statements are based on the current assumptions underlying the statements and other information with respect to the beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions of management and the financial condition, results of operations, future performance and business are only expectations of future results. Although the Company believes that the expectations reflected in the Company’s forward-looking statements are reasonable, the Company’s actual results could differ materially from those projected in the forward-looking statements as a result of, among other factors, adverse conditions in the capital and debt markets; changes in interest rates; competitive pressures from other financial institutions; the effects of continuing weakness in general economic conditions on a national basis or in the local markets in which the Company operates, including changes which adversely affect borrowers’ ability to service and repay their loans and leases; changes in the value of securities and other assets in the Company’s investment portfolio; changes in loan and lease default and charge-off rates; the adequacy of allowances for loan and lease losses; deposit levels necessitating increased borrowing to fund loans and investments; changes in government regulation; the risk that goodwill and intangibles recorded in the Company’s financial statements will become impaired; and changes in assumptions used in making such forward-looking statements, as well as the other risks and uncertainties detailed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012 and other filings submitted to the Securities and Exchange Commission. Forward-looking statements speak only as of the date on which they are made. The Company does not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date the forward-looking statements are made.

Introduction

Brookline Bancorp, Inc. (the “Company”), a Delaware corporation, operates as a multi-bank holding company for Brookline Bank and its subsidiaries; Bank Rhode Island (“BankRI”) and its subsidiaries; First Ipswich Bank (“First Ipswich” and formerly known as The First National Bank of Ipswich) and its subsidiaries; and Brookline Securities Corp.

As a commercially-focused financial institution with 46 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 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 indirect automobile loans as well as equipment financing in the New York/New Jersey metropolitan area and elsewhere.

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 on the continued acquisition of well-qualified customers, the deepening of long-term banking relationships through a full complement of products and excellent customer service, and strong risk management. The Company’s multi-bank structure retains the local-bank orientation while relieving local bank management of the responsibility for most back-office functions which are consolidated at the holding-company level. Branding and decision-making, including credit decisioning 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.

Table of Contents

The Company is subject to competition from other financial and non-financial institutions and is supervised, examined and regulated by the Board of Governors of the Federal Reserve System (“FRB”). As Massachusetts-chartered member banks, 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 Rhode Island-chartered member bank, 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 all of the Banks’ deposits. Additionally, all Massachusetts-chartered savings banks are required to be members of the Depositors Insurance Fund (“DIF”), a corporation that insures savings bank deposits in excess of the FDIC insurance limits of $250,000 per person. 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 MarketSM under the symbol “BRKL.”

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 2012 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.

Basis of 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 consolidated financial statements should be read in conjunction with the audited consolidate3d financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

In preparing these unaudited 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, the review of goodwill and intangibles for impairment, income tax accounting and status of contingencies.

Non-GAAP Financial Measures and Reconciliations 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 ratio of the allowance for loan and lease losses to originated loans and leases, the efficiency and tangible equity ratios,

Table of Contents

tangible book value per share and operating earnings metrics. 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.

Operating earnings exclude acquisition-related and other non-recurring expenses from net income, which allows the Company to measure and assess financial results on a more consistent basis from period to period. These expenses are also excluded when calculating the operating efficiency ratio. In light of diversity in presentation among financial institutions, the methodologies used by the Company for determining the non-GAAP financial measures discussed above may differ from those used by other financial institutions.

Executive Overview

Growth

Total assets remained flat at $5.1 billion at March 31, 2013 compared to December 31, 2012. The loan and lease portfolio totaled $4.2 billion, essentially unchanged as compared to December 31, 2012. While the total loan portfolio stayed flat during the first quarter of 2013, the Company’s commercial loan portfolios continued to exhibit growth. The Company’s commercial loan portfolios, which total $2.9 billion, or 69.3% of total loans and leases, increased 5.5% on an annualized basis during the first quarter of 2013. Loan growth in the Company’s commercial loan portfolios was offset by a $31.4 million decrease in the indirect automobile portfolio, due to fewer loan originations in the auto lending market.

Table of Contents

The ratio of the allowance for loan and lease losses to total loans and leases was 1.02% at March 31, 2013, compared to 0.98% at December 31, 2012. The allowance for loan and lease losses as a percentage of the total originated loan and lease portfolio, including deferred loan origination costs, was 1.34% at March 31, 2013 as compared with 1.33% at December 31, 2012. The Company continued to employ its historical underwriting methodology throughout the period ended March 31, 2013 and continued to calculate its allowance for loan and lease losses on a historically consistent basis.

Nonperforming assets at March 31, 2013 totaled $22.9 million or 0.45% of total assets, as compared with $23.7 million, or 0.46% of total assets, at December 31, 2012. Net charge-offs for the three months ended March 31, 2013 were $0.4 million, or 0.04% of average loans and leases, compared to 0.08% for the three months ended December 31, 2012 and 0.05% for the three months ended March 31, 2012.

Deposits remained constant at $3.6 billion from December 31, 2012 to March 31, 2013. The Company’s core deposits increased as a percentage of total deposits from 72.0% at December 31, 2012 to 72.6% at March 31, 2013.

The Company remains well-capitalized as defined by its regulatory requirements with capital ratios in excess of all minimum regulatory requirements. The Company’s Tier 1 leverage ratio was 9.55% at March 31, 2013. The Company’s tangible equity ratio was 9.20% at March 31, 2012, compared to 9.08% at December 31, 2012.

Net Income

For the three months ended March 31, 2013, the Company reported net income of $8.8 million, or $0.13 per diluted share, up 38.6% from the three months ended March 31, 2012. The annualized return on average assets was 0.70% for the three months ended March 31, 2013, and the annualized return on average stockholders’ equity was 5.72% for the three months ended March 31, 2013.

Net earnings from operations, which exclude acquisition-related expenses, were $8.8 million, or $0.13 per diluted share for the three months ended March 31, 2013 as compared to $10.3 million and $0.15 per diluted share for the three months ended March 31, 2012. Operating returns on average assets and average stockholders’ equity, at an annualized rate, were 0.70% and 5.72%, respectively, for the three months ended March 31, 2013.

Net interest margin was 3.70% for the three months ended March 31, 2013. The yield on interest-earning assets decreased 32 basis points from 4.70% during first quarter of 2012 to 4.38% during the first quarter in 2013, due to continued rate pressures in the lending market. The decrease in yields on interest-earning assets is offset by a decrease of 18 basis points in the Company’s overall cost of funds, from 1.02% for the three months ended March 31, 2012 to 0.84% for the three months ended March 31, 2013. The Company’s net interest margin will likely continue to be under pressure due to competitive pricing pressure in all loan categories and the continuation of a low interest-rate environment, along with the Company’s diminishing ability to reduce its cost of funds.

Results for the first quarter of 2013 included a $1.9 million provision for credit losses. The provision has decreased from $3.2 million for the first quarter of 2012. The decrease in provision was due to a lower rate of charge-offs and a lower rate of loan growth in the first quarter of 2013 as compared to the first quarter of 2012.

Non-interest income for the three months ended March 31, 2013 increased marginally as compared to March 31, 2012. Non-interest expense decreased $1.7 million, or 5.2%, from $32.4 million during the three months ended March 31, 2012 to $30.8 million for the three months ended March 31, 2013. While compensation and employee benefit expense increased due to addition of loan officers and other individuals in key support areas of the Company, professional service expenses decreased substantially in the amount of $5.0 million, or 76.7% in the first quarter of 2013, largely attributable to the acquisition of BankRI, as compared to the first quarter of 2012.

Financial Condition

General

Total assets remained constant at $5.1 billion at March 31, 2013 compared to December 31, 2012, and increased $0.2 billion from $4.9 billion at March 31, 2012.

The loan and lease portfolio was $4.2 billion at March 31, 2013, essentially unchanged as compared to December 31, 2012. However, the Company’s commercial loan portfolios grew 5.5% on an annualized basis during the first quarter

Table of Contents

of 2013. At March 31, 2013, the commercial loan and lease and commercial real estate portfolios totaled $2.9 billion, or 72.6% of total loans and leases. Offsetting the growth in the commercial portfolios was a $31.4 million decrease in the indirect automobile portfolio from December 31, 2012 to March 31, 2013, due to management’s unwillingness to originate loans at what it considers to be very low interest rates.

Cash and cash equivalents were $92.1 million at March 31, 2013 as compared to $117.1 million at December 31, 2012. The decrease during the first quarter of 2013 reflects the redeployment of cash to the Company’s securities portfolio in order to reinvest idle cash and to pay down debts. Accordingly, investment securities available-for-sale of $486.6 million increased 4.4% from December 31, 2012 to March 31, 2013 on an annualized basis, with total investment securities at 10.8% of total assets.

Deposits of $3.6 billion at March 31, 2013 were up slightly from December 31, 2012, and increased 4.8% as compared to March 31, 2012. Core deposits increased at a 3.9% annualized rate in the first quarter of 2013, raising the core deposit ratio from 72.0 percent at December 31, 2012 to 72.6% at March 31, 2013. Total borrowings decreased $33.6 million from $854.0 million at December 31, 2012 to $820.4 million at March 31, 2013.

The ratio of stockholders’ equity to total assets was 12.02% and 11.89% at March 31, 2013 and December 31, 2012, respectively. The ratio of tangible stockholders’ equity to tangible assets was 9.20% and 9.08% at March 31, 2013 and December 31, 2012.

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; indirect automobile loans; and 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, customer demands and competition.

Commercial Real Estate Loans

The commercial real estate portfolio is comprised of commercial real estate mortgage loans, multi-family mortgage loans, and construction loans and is the largest component of the Company’s overall loan portfolio, representing $2.0 billion or 47.9% of total loans and leases outstanding at March 31, 2013. Although this portfolio remained relatively constant at March 31, 2013 when compared to December 31, 2012, multi-family mortgage loans decreased $20.8 million from $606.5 million at December 31, 2012 to $585.7 million at March 31, 2013. This decrease was largely offset by an increase of $17.7 million in construction loans from $98.2 million at December 31, 2012 to $115.9 million at March 31, 2013.

For the commercial real estate portfolio, the Company focuses on making loans in the $3 million to $10 million range. 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 many factors, including, but not limited to, 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, but are not necessarily limited to, 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 frequently originated for terms of five 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.

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

About 83% of the commercial real estate loans outstanding at March 31, 2013 were secured by properties located in New England. The commercial real estate portfolio at that date was composed primarily of loans secured by office buildings ($281.7 million), retail stores ($258.7 million), industrial properties ($157.0 million) apartment buildings ($6.7 million), and mixed-use properties ($157.4 million).

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 more conservative 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.

Historically, construction and development lending has comprised a modest part of the Company’s loan originations. At March 31, 2013, originated construction loans equaled $100 million, or 3.2% of total originated loans outstanding at that date.

Commercial Loans and Leases

This portfolio, at $891.5 million at March 31, 2013, is composed of commercial loans, equipment financing loans and leases and condominium association loans and represented 21.4% of total loans outstanding, up $44.1 million, or 20.8% on an annualized basis, from $847.5 million at December 31, 2012. Equipment financing, with its traditionally higher yields, grew 26.3% on an annualized basis, from $421.0 million at December 31, 2012 to $448.7 million at March 31, 2013. This increase reflects, in part, the Company’s unwillingness to originate indirect auto loans at rates considered undesirable by the Company, and the Company’s resulting reinvestment of indirect auto repayments into equipment financing loans (see the “Indirect Automobile Loans” section below). The increase in equipment financing also reflects the growth of the Company’s tow truck lending division which reached loan balances of $65.2 million at March 31, 2013 after only twelve months of operation.

The Company focuses on making commercial loans in the $1 million to $10 million range, providing commercial banking services to companies in its market area. Over 95% of the commercial loans outstanding at March 31, 2013 were made to borrowers located in New England. 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 FHLBB index.

Credit extensions are made to established businesses on the basis of 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. 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 size of loan is determined by many factors, including, but not limited

Table of Contents

to, 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.

The equipment financing portfolio is composed primarily of loans to finance coin-operated laundry, dry cleaning, fitness, and convenience store equipment and, as stated above, now tow trucks. A significant share of the borrowers (38.9%) is located in the states of New York and New Jersey, although the customer base extends to locations throughout the United States. 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 Company focuses on making equipment financing loans and leases in the $100,000 to $500,000 range.

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.

Indirect Automobile Loans

Indirect automobile loans, which represented 12.2% of total loans outstanding at March 31, 2013, are for the purchase of automobiles (both new and used) and light-duty trucks primarily by individuals, but also by corporations and other organizations. The loans are originated through over 200 dealerships located primarily in Massachusetts, but also in Connecticut, Rhode Island and New Hampshire. Dealer relationships are reviewed periodically for application quality, the ratio of loans approved to applications submitted and loan performance.

Loan applications are generated by approved dealers and data are entered into an application processing system. A credit bureau scorecard model is used in the underwriting process. The model is based on data accumulated by nationally recognized credit bureaus and is a risk assessment tool that analyzes an individual’s credit history and assigns a numeric credit score. The model meets the requirements of the Equal Credit Opportunity Act. The application processing system sorts each application according to score ranges. Loans must meet criteria established in the Company’s loan policy. Credit profile measurements such as debt-to-income ratios, payment-to-income ratios and loan-to-value ratios are utilized in the underwriting process and to monitor the performance of loans falling within specified ratio ranges. Regarding loan-to-value ratios, the Company considers indirect automobile loans to be essentially credits that are less than fully collateralized. When borrowers cease to make required payments, repossession and sale of the vehicle financed usually results in insufficient funds to fully pay the remaining loan balance.

While the Company’s indirect automobile loan policy permits the aggregate amount of loans with credit scores of 660 or below to comprise as much as 5.0% of indirect loans outstanding, at March 31, 2013, loans with credit scores of 660 or below were 3.2% of loans outstanding. The average-dollar original weighted credit score of loans in the portfolio at that date was 748. See the subsection “Results of Operations —Provision for Credit Losses” for further information regarding loan underwriting and the average credit scores of the borrowers to whom indirect automobile loans were made. All loans require the purchase of single interest insurance by the borrower. The insurance is designed to protect the Company from loss when a loan is in default and the collateral value is impaired due to vehicle damage or the Company is unable to take possession of the vehicle.

Indirect automobile loans are assigned a particular tier based on the credit score determined by the credit bureau. The tier is used for pricing purposes only so as to assure consistency in loan pricing. Tier rates can be modified if certain conditions exist as outlined in the Company’s loan policy. The rate paid by a borrower usually differs with the “buy rate” earned by the Company. The difference is commonly referred to as the “spread.” All of the spread is paid after the end of the month in which the loan is made and is comprised of the agreed-upon rate differential multiplied by the expected average balance of the loan over its scheduled maturity. If a loan is repaid in its entirety within 90 days or before three payments have been made (depending on the agreement with the dealer), the dealer must pay the remainder of unamortized spread to the Company. If a loan is repaid after 90 days or after three payments have been made (depending on the agreement with the dealer), the dealer is not obliged to repay any

Table of Contents

part of the spread amount previously received. Spread payments to dealers are amortized as a reduction of interest received from borrowers over the life of the related loans. When loans are prepaid, any remaining unamortized balance is charged to expense at that time.

Various reports are generated to monitor receipt of required loan documents, adherence to loan policy parameters, dealer performance, loan delinquencies and loan charge-offs. Summary reports are submitted to the chief credit officer, the chief financial officer and the board of directors on a monthly basis.

Loans outstanding in the portfolio totaled $511.0 million at March 31, 2013, down from $542.3 million at December 31, 2012. Although in 2012 the automobile industry reported the highest sales since 2007 with strong sales continuing into the first quarter of 2013, competition for these loans increased significantly as large national banks and credit unions continued to price aggressively. That competition drove interest rates down and, in some cases, changed the manner in which interest rates are developed, i.e., from including a dealer-shared spread to requiring a dealer-based fee to originate the loan. Depending on the terms of the dealer’s enrollment agreement with the Company, the dealer earns this fee 90 days after a loan is originated or once the borrower makes at least three payments on the loan. The Company remains committed to the indirect automobile lending business; however because of the ongoing pricing pressures in this market and the Company’s unwillingness to significantly increase its percentage of non-prime and subprime loans, net paydowns are presently being reinvested into higher-yielding equipment financing loans and leases.

Consumer Loans

This portfolio is comprised of residential mortgage loans, home equity loans and lines, and other consumer loans and represented 18.5% of total loans outstanding at March 31, 2013 given its commercial orientation. The Company focuses its mortgage and other consumer loans on existing 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 on a servicing-released basis. 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 not generally maintained in the Company’s portfolio but are rather sold into the secondary market. In these secondary-market transactions, Brookline Bank acts as a correspondent bank while BankRI acts as broker.

Residential mortgages remained relatively flat, at $509.2 million at March 31, 2013 as compared to $511.1 million at December 31, 2012. Loan sales in the secondary market provide funds for additional lending and other banking activities. The Company had $0.8 million and $3.2 million in residential mortgage loans held-for-sale at March 31, 2013 and December 31, 2012, respectively.

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 less the amount of any existing first mortgage liens. These loan categories also remained relatively constant at $254.0 million at March 31, 2013 as compared to $261.6 million at December 31, 2012.

Other consumer loans have historically been a modest part of the Company’s loan originations. At March 31, 2013, other consumer loans originated equaled $6.1 million, or 0.2% of total originated loans outstanding at that date.

Asset Quality

Criticized and Classified Assets

The Company’s management negatively rates certain assets as “special mention,” “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 as special mention have potential weaknesses that deserve management’s

Table of Contents

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. At March 31, 2013, the Company had $54.6 million of total assets, including acquired assets that were designated as criticized. This compares to $58.6 million of assets that were designated as criticized at December 31, 2012. See Note 5, “Allowance for Loan and Lease Losses”, to the unaudited consolidated financial statements for more information on the Company’s risk rating system.

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 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.

The following table sets forth information regarding nonperforming assets at the dates indicated:

	At March 31, 2013			At December 31, 2012

Total nonperforming assets as a percentage of total assets	0.45		%	0.46		%
Total delinquent loans and leases 61-90 days past due as a percentage of total loans and leases	0.10		%	0.11		%

Nonperforming loans and leases and nonperforming assets remained virtually unchanged from December 31, 2012 to March 31, 2013. Total nonaccrual loans and leases declined in all but one loan category from December 31, 2012 to March 31, 2013. The $0.4 million decrease in commercial nonaccrual loans is primarily attributed to the upgrade of a $0.5 million credit due to the borrower bringing the loan current and remaining current throughout several quarters. The $0.3 million decrease in equipment financing nonaccrual loans is the result of one $0.5 million

Table of Contents

loan paying off during the first quarter. Nonaccrual home equity loans increased by $0.4 million. This increase is the result of four additions to nonaccruals in the home equity portfolio.

At March 31, 2013, restructured loans of $19.3 million included $8.0 million of commercial real estate mortgage loans, $0.9 million of multi-family mortgage loans, $3.3 million of commercial loans, $2.8 million of equipment financing loans, and $4.3 million of residential mortgage loans. At December 31, 2012, restructured loans included $6.7 million of commercial real estate mortgage loans, $0.9 million of multi-family mortgage loans, $3.3 million of commercial loans, $3.8 million of equipment financing loans and leases and $4.0 million of residential mortgage loans.

Allowance for Loan and Lease Losses

The allowance for loan and lease losses consists of general, specific and unallocated 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, indirect automobile loans and consumer loans, each category of which is further segregated. A formula-based credit evaluation approach is applied to each group, coupled with an analysis of certain loans for impairment.

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. See Note 1, “Basis of Presentation,” and Note 5, “Allowance for Loan and Lease Losses,” to the unaudited consolidated financial statements for descriptions of how management determines the balance of the allowance for loan and lease losses for each portfolio and class of loans.

The following tables present the changes in the allowance for loan and lease losses and the recorded investment in loans and leases by portfolio segment for the three months ended March 31, 2013 and 2012, respectively.

Allowance for loan and lease as a percentage of total loans and leases	0.90		%	0.98		%	0.98		%	0.24		%	N/A			0.87		%

The allowance for loan and lease losses was $42.5 million at March 31, 2013 or 1.02% of total loans and leases outstanding. This compared to an allowance for loan and lease losses of $41.2 million or 0.98% of total loans and leases outstanding at December 31, 2012 and an allowance for loan and lease losses of $34.4 million or 0.88% or total loans and leases outstanding at March 31, 2012. The increase in the allowance for loan and lease losses as a percentage of total loans and leases from March 31, 2012 to March 31, 2013 reflects the Company’s rebuilding of the allowance for loan and lease losses after the Bank Rhode Island acquisition, which eliminated all allowances for loan and lease losses in the acquired loans in accordance with GAAP. The allowance for loan and lease losses represents 1.34%, 1.33%, and 1.29% of originated loans and leases at March 31, 2013, December 31, 2012, and March 31, 2012, respectively.

Commercial Real Estate Loans

The allowance for commercial real estate loan losses was $20.6 million or 1.03% of total commercial real estate loans outstanding at March 31, 2013. This compared to an allowance for commercial real estate loan losses of $20.0 million or 1.00% of commercial real estate loans outstanding at December 31, 2012, and $16.8 million or 0.84% of commercial real estate loans outstanding at March 31, 2012. Excluding balances in acquired loan portfolios, the allowance for commercial real estate loan losses as a percentage of commercial real estate loans outstanding increased to 1.39% at March 31, 2013 from 1.37% at December 31, 2012.

The $0.6 million increase in the allowance for commercial real estate loans during the first three months of 2013 was primarily driven by originations. Loss factors were flat and supported by favorable asset quality trends. The ratio of total criticized commercial real estate loans to total commercial real estate loans decreased to 0.38% at March 31,

Table of Contents

2013 from 0.60% at December 31, 2012. The ratio of originated commercial real estate loans on nonaccrual to total originated commercial real estate loans increased to 0.28% at March 31, 2013 from 0.24% at December 31, 2012.

Specific reserves on commercial real estate loans were unchanged from December 31, 2012 to March 31, 2013. Management evaluates several factors in determining whether an impaired loan requires a specific reserve, including the borrower’s ability to service the loan, guarantor support and the value of available collateral.

As a percentage of average commercial real estate loans, annualized net (recoveries) / charge-offs for the three-month periods ended March 31, 2013, December 31, 2012 and March 31, 2012 were negligible. Provisions for commercial real estate loans recorded in these periods more than adequately covered charge-offs during those periods. See the “Results of Operations—Provision for Credit Losses” section below for additional information.

Commercial Loans and Leases

The allowance for commercial loan and lease losses was $11.7 million or 1.31% of total commercial loans and leases outstanding at March 31, 2013, as compared to $10.7 million or 1.26% at December 31, 2012.

The $1.4 million increase in the allowance for commercial loans and lease losses during the first three months of 2013 was primarily driven by originated loan growth of $44.1 million or 5.2% over the same period. Loss factors remained flat and were supported by stable asset quality trends. The ratio of total criticized commercial loans and leases to total commercial loans and leases was 2.2% at March 31, 2013 as compared to 1.70% at December 31, 2012. The ratio of originated commercial loans and leases on nonaccrual to total originated commercial loans and leases decreased to 0.78% at March 31, 2013 from 0.91% at December 31, 2012.

Included in the $1.4 million increase in the allowance is a $0.1 million decrease in reserves for loans specifically evaluated for impairment, from $0.7 million on loan balances of $6.5 million at December 31, 2012 to $0.6 million on loan balances of $5.6 million at March 31, 2013. Management evaluates several factors in determining whether an impaired loan requires a specific reserve, including the borrower’s ability to service the loan, guarantor support and the value of available collateral.

Net charge-offs in the commercial portfolio for the three-month periods ended March 31, 2013 and December 31, 2012 were $0.2 million and $0.2 million, respectively. As a percentage of average commercial loans and leases, annualized net charge-offs for the three-month periods ended March 31, 2013 and December 31, 2012 and March 31, 2012 were 0.08%, 0.10% and 0.14%, respectively. Provisions for commercial loans recorded in these periods more than adequately covered charge-offs. See the “Results of Operations—Provision for Credit Losses” section below for additional information.

Indirect Automobile Loans

The allowance for indirect automobile loan losses was $5.0 million or 0.98% of total indirect automobile loans outstanding at March 31, 2013, compared to $5.3 million or 0.98% of the indirect automobile portfolio outstanding at December 31, 2012.

The ratio of indirect automobile loans with borrower credit scores below 660 to the total indirect automobile portfolio increased slightly to 3.18% at March 31, 2013 from 3.12% at December 31, 2012. There were no loans individually evaluated for impairment in the indirect automobile portfolio at March 31, 2013.

Net charge-offs in the indirect automobile portfolio for the three-month periods ended March 31, 2013, December 31, 2012 and March 31, 2012 were $0.2 million, $0.4 million and $0.3 million, respectively. As a percentage of average loans and leases, annualized net charge-offs for the three-month periods ended March 31, 2013, December 31, 2012 and March 31, 2012 were 0.18%, 0.26% and 0.20%, respectively, reflecting the favorable trend in credit quality as the portfolio has been allowed to run down somewhat. Provisions for indirect automobile loans recorded in these periods more than adequately covered charge-offs during those periods. See the “Results of Operations—Provision for Credit Losses” section below for additional information.

Consumer Loans

The allowance for consumer loan losses, including residential loans and home equity loans and lines of credit, was $2.6 million or 0.34% of total consumer loans outstanding at March 31, 2013. This compared to an allowance for consumer loan losses of $2.5 million or 0.32% of consumer loans outstanding at December 31, 2012.

The allowance on consumer loans was relatively flat compared to the prior quarter. The ratio of residential and home equity loans with loan-to-value ratios greater than 80% increased to 8.16% of total residential and home equity loans at March 31, 2013 from 7.20% at December 31, 2012. Moreover, the ratio of originated consumer loans on nonaccrual to total originated consumer loans (including deferred origination costs) decreased to 0.39% at March 31, 2013 from 0.44% at December 31, 2012. Management evaluates several factors in determining whether an impaired loan requires a specific reserve, including the borrower’s ability to service the loan, guarantor support and the value of available collateral, and believes these reserve levels are adequate.

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 for the Company even if these home equity loans are not delinquent. These 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 exposure to loss is not considered to be high due to the combination of current property values, the low level of losses experienced in the past few years and the low level of loan delinquencies at March 31, 2013. If the local economy weakens, however, a rise in losses in those loan classes could occur. Historically, losses in these classes have been low.

The reserve for loans specifically evaluated for impairment at March 31, 2013 is $0.6 million on loan balances of $4.8 million, unchanged from December 31, 2012.

Net charge-offs in the consumer portfolio for the three-month periods ended March 31, 2013, December 31, 2012 and March 31, 2012 were $26,000, $300,000 and $7,000, respectively. As a percentage of average commercial loans and leases, annualized net charge-offs for the three-month periods ended March 31, 2013, December 31, 2012 and March 31, 2012 were 0.01%, 0.14% and less than 0.01%, respectively. Provisions for consumer loans recorded in these periods more than adequately cover charge-offs.

Unallocated Allowance

The unallocated allowance recognizes the estimation risk associated with the allocated general and specific allowances, incorporates management’s evaluation of existing conditions that are not included in the allocated allowance determinations and protects against potential losses outside of the ordinary course of business. These conditions are reviewed quarterly by management and include general economic conditions, credit quality trends, loan and lease mix, and internal loan review and regulatory examination findings. Causes of losses outside the normal course of business include but are not limited to fraudulently obtained loans where there is no primary or secondary source of repayment; catastrophic and uninsured property loss where collateral is destroyed with no compensation; and legal documentation flaws that compromise security interests in collateral assets or the availability of guarantors.

The unallocated allowance for loan and lease losses was $2.7 million at March 31, 2013, compared to $2.6 million at December 31, 2012. The unallocated portion of the allowance for loan and lease losses increased $0.1 million during the first three months of 2013, largely as a result of a change in the mix of loans in the loan and lease portfolio.

Investments

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. Securities available-for-sale are employed 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 acceptable types of investments, 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. As a general guideline, the Company maintains no less than 10% of total assets in investments, including cash and cash equivalents.

Total investments, including cash and cash equivalents, decreased $19.7 million, or 3.4%, since December 31, 2012. Total investments were 11.3% of total assets at March 31, 2013, compared to 11.6% of total assets at December 31, 2012.

Maturities, calls and principal repayments totaled $31.8 million for the three months ended March 31, 2013 compared to $49.3 million for the three months ended December 31, 2012. During the first three months of 2013, the Company purchased $40.0 million of available-for-sale securities compared to $73.8 million for the three months ended December 31, 2012 and none during the first three months of 2012. In the first three months of 2013 and 2012, the Company did not sell any available-for-sale securities. In the last three months of 2012, the Company sold one security for proceeds of $9.0 million and a realized gain of $0.1 million.

Securities available-for-sale are recorded at fair value, which is primarily obtained from a third-party pricing service. At March 31, 2013, the fair value of all securities available-for-sale was $486.6 million and carried a total of $3.36 million of net unrealized gains at the end of the quarter, compared to $5.4 million at December 31, 2012 . Of the $486.6 million in securities available for sale, $148.0 million, or 30.4%, of the portfolio, had unrealized losses of $1.6 million. This compares to $47.6 million, or 9.9% of the portfolio with gross unrealized losses of $0.6 million at December 31, 2012. Management believes that these negative differences between amortized cost and fair value reflect the changes in the level of interest rates between the time of purchase and at time of measurement and that it will recover the amortized cost basis of the securities and that it is more likely than not that it will not sell the securities before recovery. As such, management has determined that the securities are not other-than-temporarily impaired at March 31, 2013. 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. See Note 3, “Investment Securities,” to the unaudited consolidated financial statements for more information on the Company’s various investments.

U.S. Government-Sponsored Enterprises (“GSEs”) — The Company invests in securities issued by of U.S. Government-sponsored enterprises (“GSEs”), including GSE debt securities, 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 (“Freddie Mac”), the Government National Mortgage Association (“GNMA”), the Federal Home Loan Banks and the Federal Farm Credit Bank. At March 31, 2103, none of those obligations is backed by the full faith and credit of the U.S. Government, except for GNMA MBSs and CMOs, and Small Business Administration (“SBA”) commercial loan asset-backed securities with an estimated fair value of $14.6 million.

At March 31, 2013, the Company held GSE mortgage-related securities with a total fair value of $406.2 million and a net unrealized gain of $2.8 million. At December 31, 2012, the Company held GSE mortgage-related securities with a total fair value of $386.6 million and a net unrealized gain of $5.0 million. During the first three months of 2013, the Company purchased a total of $40.0 million in GSE CMOs and GSE MBSs to reinvest matured cash flow.

Private-Label CMOs — At March 31, 2013, the Company held private issuer CMO-related securities with a total fair value of $5.8 million and a net unrealized gain of $0.2 million. At December 31, 2012, the Company held private issuer CMO-related securities with a total fair value of $6.9 million and a net unrealized gain of $0.1 million.

Auction-Rate Municipal Obligations and Municipal Obligations — The auction-rate obligations owned by the Company were rated “AAA” at the time of acquisition due, in part, to the guarantee of third-party insurers who would have to pay the obligations if the issuers failed to pay the obligations when they become due. During the financial crisis certain third-party insurers experienced financial difficulties and were not able to meet their contractual obligations. As a result, auctions failed to attract a sufficient number of investors and created a liquidity problem for those investors who were relying on the obligations to be redeemed at auction. Since then, there has not been an active market for auction-rate municipal obligations.

Based on an evaluation of market factors, the estimated fair value of the auction-rate municipal obligations owned by the Company at March 31, 2013 was $2.0 million with a corresponding net unrealized loss of $0.1 million. Full collection of the obligations is expected because the financial condition of the issuers is sound, none of the issuers has 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 unrealized losses.

The Company owns municipal securities with an estimated fair value of $1.1 million which approximates amortized cost at March 31, 2013. Full collection of the obligations is expected because the financial condition of the issuers is sound, none of the issuers has 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 unrealized losses.

Corporate Debt Obligations — From time to time, the Company will invest in high-quality corporate obligations to provide portfolio diversification and improve the overall yield on the portfolio. The Company owned five corporate obligation securities with a total fair value of $10.8 million and total net unrealized gains of $0.3million at March 31, 2013. All but one of these securities are investment grade which is currently in an unrealized gain position.

Trust Preferred Securities and Pools— Trust preferred securities represent subordinated debt issued by financial institutions. These securities are sometimes pooled and sold to investors through structured vehicles known as PreTSLs. When issued, PreTSLs are divided into tranches or segments that establish priority rights to cash flows from the underlying trust preferred securities. At March 31, 2013, the Company owned three trust preferred securities and two PreTSL pools with a total fair value of $2.5 million and a total net unrealized loss of $0.2 million. The Company monitors these pools closely for impairment due to a history of defaults experienced on the part of the banks underlying the trust preferred securities.

Marketable Equity Securities — At March 31, 2013, the Company owned marketable equity securities with a fair value of $1.4 million, including net unrealized gains of $0.1 million.

Restricted Equity Securities

Federal Reserve Bank Stock

The Company invests in the stock of the Federal Reserve Bank of Boston, as required by its subsidiary Banks’ membership in the Federal Reserve System. At March 31, 2013, the Company owned stock in the Federal Reserve Bank of Boston with a carrying value of $16.0 million.

FHLBB Stock

The Company invests in the stock of the FHLBB as one of the requirements to borrow. The Company maintains an excess balance of capital stock of $13.7 million which allows for additional borrowing capacity at each subsidiary institution. At March 31, 2013, the Company owned stock in the FHLBB with a carrying value of $50.1 million. The FHLBB stated that it remained in compliance with all regulatory capital ratios at March 31, 2013 and, based on the most recent information available, was classified as “adequately capitalized” by its regulator.

Premises and Equipment

Corporate Headquarters

In addition to building and land costs of $14.0 million, the Company had previously entered into contracts totaling $23.6 million for capital expenditures associated with the rehabilitation of its new headquarters in Boston, of which $21.4 million was incurred in 2012. Of the remaining $2.2 million in refurbishment expenses owed, $1.8 million was capitalized in the first quarter of 2013. A portion of the Company’s new headquarters is rented to third-party tenants and the remaining refurbishment commitments are mostly related to those leases.

Core Operating Systems

The Company has also entered into contracts associated with the conversion of its core operating systems. Brookline Bank and First Ipswich were successfully converted to a new core operating system in 2012. BankRI is anticipated to convert to the Company’s core operating system late in the second quarter of 2013. The useful life of the core processing system is 7.5 years, and ongoing maintenance and operation contracts extend over seven years. At March 31, 2013, $0.7 million in conversion-related expenditures have been capitalized.

Table of Contents

Total deposits remained flat at $3.6 billion at March 31, 2013 compared to December 31, 2012. Deposits as percentage of total assets increased slightly from 70.3% at December 31, 2012 to 71.0% at March 31, 2013. During the first quarter of 2013, core deposits increased $25.5 million, or 3.9% on an annualized basis, rising from 72.0% of total deposits at December 31, 2012 to 72.6% of total deposits at March 31, 2013. Certificate of deposit accounts decreased $15.7 million, or 6.2% on an annualized basis, during the first three months in 2013. Certificates of deposit have also fallen as a percentage of total deposits from 28.0% at December 31, 2012 to 27.4% at March 31, 2013. The Company does not rely on brokered deposits.

The Company believes the ongoing shift toward core deposits is due in part to expansion of its cash management capabilities, more effort in seeking deposits from existing customer relationships and the desire of certain depositors to place their funds in a more strongly capitalized financial institution and in more liquid accounts. A rise in interest rates could cause a shift from core deposit accounts to certificate of deposit accounts with longer maturities. Generally, the rates paid on certificates of deposit are higher than those paid on core deposit accounts.

Borrowed Funds

Advances from the FHLBB

Although 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 opportunistically 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 as collateral certain qualifying assets, 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 Federal Reserve “discount window” and on $119.0 million of lines of credit as necessary.

FHLBB borrowings decreased by $31.2 million to $759.7 million at March 31, 2013 from the December 31, 2012 balance of $790.9 million. The decrease in FHLBB borrowings was primarily due to deposit growth outpacing loan growth.

The following table sets forth certain information regarding FHLBB advances for the periods indicated:

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 Company customers decreased $13.0 million during the three months ended March 31, 2013 to $52.0 million as customers shifted funds into other deposit products.

Subordinated Debt

In the acquisition of Bancorp Rhode Island, Inc., the Company assumed three subordinated debentures issued by a subsidiary of Bancorp Rhode Island, Inc. During the first three months of 2013, the Company repaid $3.0 million in subordinated debt before scheduled maturity in 2031 due to the fixed, high cost of the borrowing. The remaining two subordinated debentures are summarized below:

Derivative Financial Instruments

The Company has entered into interest-rate swaps with certain of its commercial customers and concurrently enters into offsetting swaps with third-party financial institutions. The Company did not have derivative fair value hedges or derivative cash flow hedges at March 31, 2013 or December 31, 2012. The following table summarizes certain information concerning the Company’s interest-rate swaps at March 31, 2013:

Stockholders’ Equity and Dividends

The Company’s total stockholders’ equity was $614.0 million at March 31, 2013, a $1.9 million increase compared to $612.1 million at December 31, 2012. The increase primarily reflects net income of $8.8 million for the three months ended March 31, 2013, offset by dividends paid of $6.0 million in that same period. The dividends paid in the first quarter of 2013 represented the Company’s 56th consecutive quarter of dividend payments, and the 44th consecutive quarter in which the Company paid a regular dividend of $0.085.

Stockholders’ equity represented 12.0% of total assets at March 31, 2013 and 11.9% at December 31, 2012. Tangible stockholders’ equity (total stockholders’ equity less goodwill and identified intangible assets, net) represented 9.2% of tangible assets (total assets less goodwill and identified intangible assets, net) at March 31, 2013 and 9.1% at December 31, 2012.

Results of Operations

The primary drivers of the Company’s operating income are net interest income, which is strongly affected by the net yield on 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 depends 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 (decreases) 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” on page 74. 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” on pages 72 and 73.

Because the Company’s assets and liabilities are not identical in duration and in repricing dates, the differential between the asset and liability repricing and duration 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 under “Interest-Rate Risk” on page 81.

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

Table of Contents

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” on pages 57 to 59.

General

The Company’s net income of $8.8 million for the three months ended March 31, 2013 decreased by $3.1 million, or 25.7%, compared to the three months ended December 31, 2012. Compared to the three months ended March 31, 2012, operating income decreased $1.5 million, or 14.6%, after adjustment for acquisition-related expenses of $4.0 million (after-tax) that were incurred during the first quarter of 2012 and which were associated with the acquisition of Bancorp Rhode Island, Inc. Diluted operating EPS decreased 23.5% compared to the fourth quarter of 2012, from $0.17 to $0.13, and decreased 13.3% compared to the first quarter of 2012, from $0.15 to $0.13. This decline in quarterly net income from December 31, 2012 to March 31, 2013 reflects a reduction in net interest income of $0.9 million, a reduction in non-interest income of $3.2 million and increase in non-interest expense of $1.9 million, offset by reduction in provision for credit losses of $1.4 million.

Earnings in the first quarter of 2013 represented a return on average assets of 0.70% and a return on average stockholders’ equity of 5.72%, as compared to a return on average assets of 0.93% and a return on average stockholders’ equity of 7.76% for the fourth quarter of 2012 and a return on average assets of 0.52% and a return on average stockholders’ equity of 4.25% for the first quarter of 2012. Operating earnings in the first quarter of 2013 represented an operating return on average assets of 0.70% and an operating return on average stockholders’ equity of 5.72%, as compared to an operating return on average assets of 0.93% and a return on average stockholders’ equity of 7.76% for the fourth quarter of 2012 and an operating return on average assets of 0.85% and a return on average stockholders’ equity of 6.90% for the first quarter of 2012.

Net Interest Income

Net interest income for the first three months of 2013 was $43.7 million, essentially unchanged from the $43.6 million posted in the first quarter of 2012. The impact of the persistent low interest-rate environment offset the benefits of increased loan volume quarter-over-quarter, with increase in interest income due to volume of $3.5 million offset by reductions in interest income due to rate of $4.7 million quarter-over-quarter. This $1.2 million decline in interest income was ameliorated by a $1.4 million decrease in interest expense quarter-over-quarter. The majority of which resulted from decreases in interest rates paid on deposits and other borrowed funds.

Decreases in interest expense for the quarter ended March 31, 2013 were not enough to offset decreases in interest income. Rate-related decreases on interest income of $2.5 million in the first quarter of 2013 were partially offset by volume-related increases in interest income of $1.3 million. This $1.2 million net change in interest income from December 31, 2012 to March 31, 2013 was reduced, by volume- and rate- driven decline in interest expense of $0.5 million in the first quarter of 2013.

As a result, net interest margin decreased by 17 basis points, from 3.87% for the first three months of 2012 to 3.70% for the first three months of 2013. Competitive pressures on loan pricing resulted in decreases in the Company’s weighted average interest rate on loans (prior to purchase accounting adjustments) from 5.11% at March 31, 2012 to 4.80% at March 31, 2013. Interest amortization and accretion on acquired loans totaled $1.2 million and contributed 9 basis points to loan yields during the first quarter of 2013, compared to an addition of $1.2 million and 10 basis points in the first quarter of 2012.

Funding costs declined over the past year, decreasing from 1.02% for the first three months of 2012 to 0.84% for the first three months of 2013. The Company’s reduction in interest rates offered on money market accounts and certificates of deposit contributed significantly to the reduction in the cost of interest-bearing deposits, declining 11 basis points and 9 basis points, respectively, from March 31, 2012 to March 31, 2013.

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. It may also be negatively affected by changes in the amount of purchase accounting accretion and amortization included in interest income and interest expense.

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.

Net interest income for the first three months of 2013 decreased $0.9 million compared to the three months ended December 31, 2012 due in large part to a combination of the low interest-rate environment, which decreased net interest income by $2.3 million, and to a lesser degree, to the decline in the indirect automobile portfolio which resulted in a volume-based reduction in net interest income of $0.6 million. Interest-rate reductions of $2.5 million on earning assets were offset by funding-rate reductions of $0.3 million.

Net interest income for the first quarter of 2013 was essentially unchanged compared to the first quarter of 2012. Overall, quarterly interest and dividend income decreased $1.2 million quarter-over-quarter and was offset by a similar reduction in interest expense (after adjusting for tax-exempt income). A $3.7 million quarter-over-quarter increase in interest income due to loan growth was almost fully offset by lower interest rates on those assets.

This is primarily the result of $4.0 million in nonrecurring after-tax expenses associated with the acquisition of Bancorp Rhode Island, Inc. on January 1, 2012. Operating earnings for the first quarter of 2013 and 2012, respectively, were $8.8 million and $10.3 million, or down $1.5 million.

Interest income from loans was $49.5 million for the first three months of 2013, resulting in a yield on total loans of 4.80%. This compares to $49.6 million of interest on loans and a yield of 5.11% for the first three months of 2012. Quarter-over-quarter increases in interest income on loans and leases of $3.7 million resulting from increased volume offset the $3.8 million decrease in loan interest income resulting from interest-rate reductions on loans. Interest income on loans and leases decreased $1.1 million from the fourth quarter 2012 to first quarter 2013 with declines in loan interest income of $2.3 million from rate reductions partially offset by $1.2 million of volume-driven increases in interest income on loans and leases. Declines in the yields on all the loan portfolios reflect the high rate of loan refinancings and the intense pricing competition which continues to characterize the Company’s lending markets.

Table of Contents

On an overall basis, the $0.1 million decline quarter-over-quarter in quarterly interest income on loans is composed of a decrease in interest income on loans of $3.8 million due to the lower rate environment, offset by an increase of $3.7 million in interest income on loans due to the $247.4 million increase in average loans outstanding.

Interest Income — Investments

Total investment income (consisting of interest on short-term investments, investment securities available-for-sale, and restricted equity securities) was $2.2 million for the first three months of 2013 compared to $3.4 million for the first three months of 2012. This decrease in total investment income of $1.1 million, or 34.5%, is largely a result of rate-driven reduction stemming from the paydown of higher-coupon MBSs and CMOs which were replaced by similar but lower-yielding securities. The yield on investments decreased from 2.2% for the three months ended March 31, 2012 to 1.5% for the three months ended March 31, 2013.

Deposits

The Company’s quarter-over-quarter reduction in interest rates offered on deposits, particularly savings and money market accounts and certificates of deposit, contributed $0.6 million to the reduction in the cost of interest-bearing deposits. As a result, the cost of total interest-bearing deposits decreased from 0.76% in the first three months of 2012 to 0.65% in the first three months of 2013.

Rate reductions in the first quarter of 2013 represented the majority of the $0.2 million decrease in interest expense on deposits from the fourth quarter 2012. Included in the cost of interest-bearing deposits was $0.2 million and $0.4 million, in premium amortization on certificates of deposit in the first quarters of 2013 and 2012, respectively.

Interest paid on borrowed funds decreased by $0.7 million, or 19.5% during the first three months of 2013 as compared to the year-ago period. Decreases in borrowing rates since the first quarter of 2012 resulted in a reduction in debt-related interest expenses of $0.9 million, partially offset by a $0.1 million increase in interest expense due to an increase in borrowed funds. Premium amortization on borrowed funds acquired in the BankRI acquisition decreased interest expense by $0.9 million and $1.0 million in the first quarters of 2013 and 2012, respectively.

Provision for Credit Losses

The provisions for credit losses are set forth below:

	Three Months Ended March 31,
	2013			2012
	(In Thousands)
Provisions for loan and lease losses:
Commercial real estate	$	566		$	1,319
Commercial	1,162			1,344
Indirect automobile	(72		)	344
Consumer	77			255
Unallocated	66			(15		)
Total provision for loan and lease losses	1,799			3,247
Unfunded credit commitments	56			—
Total provision for credit losses	$	1,855		$	3,247

The provisions for credit losses during the first three months of 2013 and 2012 were $1.9 million and $3.2 million, respectively. The $1.4 million quarter-over-quarter decrease in the first-quarter provision for loan and lease losses was due in part to a slower pace of commercial real estate, indirect automobile and consumer loan originations in the first quarter of 2013 as compared to the first quarter of 2012, offset by a faster pace of originations in equipment financing and construction loans. Additional provisions on acquired loans during the first three months of 2013 were immaterial, given that there was minimal deterioration in projected cash flows on acquired loans from the date of acquisition for BankRI and from December 31, 2011 for First Ipswich. 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.

The liability for unfunded credit commitments, which is included in other liabilities, was $0.8 million at March 31, 2013 and $0.7 million at December 31, 2012. During the first quarter of 2013, the liability for unfunded credit commitments increased by $0.1 million to reflect changes in the estimate of loss exposure associated with credit commitments. This increase increased the provision for credit losses by the same amount during the first three months of 2013. No credit commitments were charged off against the liability account in the three-month periods ended March 31, 2013 or 2012, respectively.

Non-Interest Income

The following table sets forth the components of non-interest income for the periods indicated:

	Three Months Ended March 31,						Dollar			Percent
	2013			2012			Change			Change

Total non-interest income	$	3,327		$	3,595		$	(268	)	-7.5	%

Fees, charges and other income are the major sources of non-interest income for the Company and include deposit-related fees, indirect automobile and consumer loan fees, and other service fees. Total non-interest income decreased by $0.3 million, or 7.5%, from $3.6 million for the first three months of 2012 to $3.3 million for the first

three months of 2013. The decrease is primarily due to a larger loss on tax-efficient investments in affordable housing projects.

Non-Interest Expense

The following table sets forth the components of non-interest expense:

Total non-interest expense	$	30,772	$	32,449	$	(1,677	)	-5.2	%

Non-interest expense for the first three months of 2013 decreased $1.7 million compared to the year-ago period. When non-interest expense for the three months ended March 31, 2012 is adjusted to exclude expenses of $5.4 million related to the acquisition of BankRI, operating non-interest expense increased $3.7 million, or 11.5%. The increase is largely a result of costs associated with the Company’s infrastructure build. The reduction in non-interest expense in the first three months of 2013 as compared to the first three months of 2012 resulted in the Company’s efficiency ratio decreasing from 68.71% for the three months ended March 31, 2012 to 65.48% for the three months ended March 31, 2013. This reduction, however, is entirely due to acquisition-related expenses incurred during the first three months of 2012. Disregarding these acquisition-related expenses, which accounted for the decrease in professional services quarter-over-quarter, the Company’s operating efficiency ratio increased from 57.28% for the first three months of 2012 to 65.48% for the first three months of 2013.

Compensation and employee benefit expense increased $1.6 million, or 11.0% as compared to the first quarter of 2012. This increase is a result of the addition of loan officers and other individuals in key support areas of the Company including the Loan Review, Credit Administration, Compliance, Human Resources, Legal and Finance functions. Future compensation and employee benefit expense synergies from the BankRI acquisition will not be realized until after BankRI’s core system conversion, expected to occur in the latter part of the second quarter of 2013.

Equipment and data processing expense increased 5.9% as compared to the first quarter of 2012, mainly due to one-time costs incurred in conjunction with BankRI’s core system conversion. Equipment and data processing expense increased 5.9% as compared to the first quarter of 2012, mainly due to one-time costs incurred in conjunction with BankRI’s core system conversion. Other expense increased $1.2 million as a result of increases in several areas including telephone, repossessed assets, postage and office supply expense.

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 its 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 and sales of securities from the available-for-sale portfolio.

Deposits, which are considered the most stable source of liability liquidity, totaled $3.6 billion at March 31, 2013, and represented 71.6% of total funding (the sum of total deposits, total borrowings, and stockholders’ equity), compared to deposits of $3.6 billion, or 71.2% of total funding, at December 31, 2012. Core deposits, which consist of demand checking, NOW, savings and money market accounts, totaled $2.6 billion at March 31, 2013 and represented 72.6% of total deposits, compared to core deposits of $2.6 billion, or 72.0% of total deposits, at December 31, 2012. While deposits are considered the most reliable source of liquidity, the Company is careful to increase deposits without adversely impacting the weighted average cost of those 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 $820.4 million at March 31, 2013, representing 16.1% of total funding, compared to $854.0 million, or 16.8% of total funding, at December 31, 2012. As members of the FHLBB, the Banks have access to both short- and long-term borrowings. The Banks also have access to funding through retail repurchase agreements, brokered deposits and $119 million of uncommitted lines of credit, and may utilize additional sources of funding in the future, including borrowings at the Federal Reserve “discount window,” to supplement its liquidity. At March 31, 2013, the Company’s total borrowing limit from the FHLBB for advances and repurchase agreements was $1.1 billion, based on the level of qualifying collateral available for these borrowings.

In general, the Company seeks to maintain a high degree of liquidity and targets cash and equivalents and available-for-sale security balances of between 10% and 30% of total assets. At March 31, 2013, cash and equivalents and available-for-sale securities totaled $579.2 million, or 11.3% of total assets. This compares to $598.9 million, or 11.6% of total assets at December 31, 2012.

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.

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 come in a variety of forms, including repricing risk, yield-curve risk, basis risk, and prepayment risk. Repricing risk exists 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 the changes in the shape of the yield curve could have different effects on the Company’s assets and liabilities. Basis risk exists 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 at a time of 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 Asset/Liability Committee and 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 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, and the 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 also may 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 at March 31, 2013 or December 31 2012. 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

Table of Contents

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 the 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 at March 31, 2013.

At March 31, 2013, 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 shocks 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, 2013					December 31, 2012					March 31, 2012
Gradual Change in Interest-Rate Levels	Dollar Change			Percent Change		Dollar Change			Percent Change		Dollar Change		Percent Change
	(Dollars in Thousands)

Up 200%	$	1,635		0.93	%	$	1,513		0.86	%	$	4,299	2.57	%
Up 100%	687			0.39	%	713			0.41	%	2,092		1.25	%
Down 100%	(2,193		)	-1.25	%	(39		)	-0.02	%	614		0.37	%

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, 2013, the Company’s one-year cumulative gap was a negative $574.0 million, or negative 11.2% of total assets, compared with a negative $502.3 million, or 9.8% of total assets at December 31, 2012 and a negative $386.8 million, or 7.9% of total assets at March 31, 2012.

For additional discussion on interest-rate risk see Item 7A, “Quantitative and Qualitative Disclosures about Market Risk” on pages 83 to 86 of the Company’s 2012 Annual Report on Form 10-K.

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.

Other Market Risks

Included in the Company’s investment portfolio at March 31, 2013 were marketable equity securities with a market value of $1.3 million. That amount includes net unrealized gains of $0.1 million. Movements in the market price of securities may affect the amount of gains or losses ultimately realized by the Company from the sale of its equity securities.

Item 4. Controls and Procedures

Controls and Procedures

Under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief 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 Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Table of Contents

In conjunction with the Company’s core systems conversions and its ongoing consolidation of its subsidiary banks’ back-office operations, shared services, and policies and procedures, the Company continues to focus on consolidating and enhancing internal controls over financial reporting. 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 control 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. In addition, the effectiveness of the Company’s internal control over financial reporting as of the end of the period covered by this report has been audited by KPMG LLP, an independent registered public accounting firm.

Management’s Report on Internal Control Over Financial Reporting as of December 31, 2012 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, 2012.
