Notes to Unaudited Consolidated Financial Statements

At and for the Nine Months Ended September 30, 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 23 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 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, municipal and retail deposits, origination of mortgage loans on commercial and residential real estate located principally in Massachusetts and Rhode Island, origination of commercial loans and leases to small- and mid-sized businesses, 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.

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.

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 Accounting Standards Update (“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. See Note 7, “Comprehensive Income.”

In July 2013, the FASB issued ASU 2013-10, Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes. This ASU amends ASC 815 to allow entities to use the Fed Funds Effective Swap Rate, in addition to U.S. Treasury rates and LIBOR, as a benchmark interest rate in accounting for fair value and cash flow hedges in the United States. This ASU also eliminates the provision from ASC 815-20-25-6 that prohibits the use of different benchmark rates for similar hedges except in rate and justifiable circumstances. This ASU is effective prospectively for qualifying new hedging relationship entered into on or after July 17, 2013, and for hedging

relationship redesignated on or after that day. As of September 30, 2013, the Company did not have any fair value and cash flow hedges. The adoption of ASU No. 2013-10 did not have a material impact on the Company’s financial statements.

In July 2013, the FASB issued ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. This ASU provides guidance on financial statement presentation of unrecognized tax benefits (“UTBs”) when a net operating loss (“NOL”) carryforward, a similar tax loss, or a tax credit carryforward exists. The FASB’s objective in issuing this ASU is to eliminate diversity in practice resulting from a lack of guidance on this topic in current U.S. GAAP. Under this ASU, an entity must present a UTB, or a portion of a UTB, in the financial statements as a reduction to a deferred tax asset (“DTA”) for an NOL carryforward, a similar tax loss, or a tax credit carryforward except when: (a) an NOL carryforward, a similar tax loss, or a tax credit carryforward is not available as of the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position; (b) the entity does not intend to use the DTA for this purpose (provided that the tax law permits a choice). If either of these conditions exists, an entity should present a UTB in the financial statements as a liability and should not net the UTB with a DTA. New recurring disclosures are not required because the ASU does not affect the recognition or measurement of uncertain tax positions under ASC 740. This amendment does not affect the amounts public entities disclose in the tabular reconciliation of the total amounts of UTBs because the tabular reconciliation presents the gross amount of UTBs. This ASU is effective for fiscal years beginning after December 15, 2013, and interim periods within those years. The amendments should be applied to all UTBs that exist as of the effective date. Entities may choose to apply the amendments retrospectively to each prior reporting period presented. As of September 30, 2013, the Company did not have a UTB. Management will assess the applicability of this ASU after it becomes effective in the first quarter of 2014.

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 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.

Table of Contents

BROOKLINE BANCORP, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements

At and for the Nine Months Ended September 30, 2013 and 2012

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 that were in an unrealized loss position at September 30, 2013, prior to the recovery of their amortized cost basis. 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 September 30, 2013, 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 $13.1 million, compared to $10.0 million at December 31, 2012.

At September 30, 2013, the Company held GSE debentures with a total fair value of $20.2 million and a net unrealized gain of less than $0.1 million. At December 31, 2012, the Company held GSE debentures with a total fair value of $69.8 million and a net unrealized gain of $0.3 million. At September 30, 2013, none of the twelve securities in the Company’s portfolio were in unrealized loss positions. All securities are performing and backed by the implicit or explicit guarantee of the U.S. Government.

At September 30, 2013, the Company held SBA securities with a total fair value of $0.3 million and a net unrealized loss of less than $0.1 million. At December 31, 2012, the Company held GSE debentures with a total fair value of $0.4 million and a net unrealized loss of less than $0.1 million. At September 30, 2013, seven of the nine securities in the Company’s portfolio were in unrealized loss positions, which represented 0.8% of the amortized cost of the securities. All securities are performing and backed by the implicit or explicit guarantee of the U.S. Government.

At September 30, 2013, the Company held GSE mortgage-related securities with a total fair value of $425.5 million and a net unrealized loss of $8.7 million. This compares to a total fair value of $386.6 million and a net unrealized gain of $5.0 million at December 31, 2012. During the nine months ended September 30, 2013, the Company purchased $111.4 million in GSE CMOs and GSE MBSs to reinvest cash from matured securities. This compares to a total of $252.3 million during the same period in 2012. At September 30, 2013, 80 of the 235 securities in the Company’s portfolio were in unrealized loss positions, which represented 3.0% of the amortized cost of the securities. All securities are performing and backed by the implicit or explicit guarantee of the U.S. Government.

Private-Label CMOs

At September 30, 2013, the Company held private-issuer CMO-related securities with a total fair value of $4.1 million and a net unrealized gain of less than $0.1 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. At September 30, 2013, two of the eleven securities in the Company’s portfolio were in unrealized loss positions, which represented 2.9% of the amortized cost of the

Table of Contents

At and for the Nine Months Ended September 30, 2013 and 2012

securities. All securities are performing and while one security was downgraded during the third quarter of 2013, the security is in an unrealized gain position as the underlying credit metrics have not deteriorated over the third quarter of 2013.

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 September 30, 2013 was $1.8 million, with a corresponding net unrealized loss of $0.1 million. This compares to $2.0 million with a corresponding net unrealized loss of $0.1 million at December 31, 2012. At September 30, 2013, two of the two securities in the Company’s portfolio were in unrealized loss positions, which represented 6.6% of the amortized cost of the securities. 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 September 30, 2013. This compares to a total fair value of $1.1 million which also approximated amortized cost at December 31, 2012. At September 30, 2013, none of the two securities in the Company’s portfolio were in unrealized loss positions. 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 ten corporate obligation securities with a total fair value of $23.5 million and total net unrealized gains of $0.4 million at September 30, 2013. This compares to eight corporate obligation securities with a total fair value of $10.7 million and total net unrealized gains of $0.2 million at December 31, 2012. All but one of the securities are investment grade. This non-investment-grade security is currently in an unrealized gain position. At September 30, 2013, none of the ten securities in the Company’s portfolio were in unrealized loss positions. 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, except for one security 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. During the nine months ended September 30, 2013, the Company purchased $12.7 million in corporate obligations. The Company did not purchase any corporate obligations in the same period in 2012.

Trust Preferred Securities and Trust Preferred 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 trust preferred pools (“PreTSLs”). When issued, PreTSLs are divided into tranches or segments that establish priority rights to cash flows from the underlying trust preferred securities. At September 30, 2013, the Company owned three trust preferred securities and two PreTSL pools with a total fair value of $2.6 million which approximate amortized costs. This compares to three trust preferred securities and two PreTSL pools with a total fair value of $2.5 million and a total net unrealized loss of $0.3 million at December 31, 2012. At September 30, 2013, three of the five securities in the Company’s portfolio were in unrealized loss positions, which represents 12.1% of the amortized cost of the securities. 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.

At September 30, 2013, one PreTSL received a $0.2 million principal and interest payment. This payment, which was reported in non-interest income, was applied to the amortized cost with the remainder applied to gains on other assets in accordance with the cost recovery method. The payment completely paid down the amortized cost of this security and future

payments will be recognized as gains on other assets The other PreTSL was designated “PreTSL B.” The Company monitors this pool closely for impairment due to a history of defaults experienced on the part of the banks underlying the trust preferred security. The following tables summarize the pertinent information at September 30, 2013 that was considered in determining whether OTTI existed on this PreTSL.

(1) The amortized cost reflects previously recorded credit-related OTTI charges recognized in earnings for the applicable securities.

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 September 30, 2013 was as follows:

PreTSL B has experienced $86.0 million in deferrals/defaults, or 25.2% of the security’s underlying collateral, to date. During the third 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 15.7% over its remaining life, the security’s current amortized cost (99.5% of current par), $108.0 million in excess subordination (42.2% of outstanding performing collateral) and the Company’s intent and ability to hold the security until recovery, Management believes that no OTTI is warranted at this time.

At September 30, 2013, there is no OTTI recognized in other comprehensive income on these securities.

Marketable Equity Securities

At September 30, 2013, the Company owned marketable equity securities with a fair value of $1.3 million, including net unrealized gains of less than $0.1 million. This compares to a fair value of $1.3 million and net unrealized gains of $0.1 million at December 31, 2012. At September 30, 2013 one out of the total four securities in the Company’s portfolio was in an unrealized loss position, which represents 0.4% of the amortized cost of the securities.

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 September 30, 2013, there were no remaining callable GSE securities in the investment portfolio. 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 security sales during the nine-month period ended September 30, 2013.

Subsequent to acquisition, management quarterly 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 nine months ended September 30, 2013 and 2012, accretable yield adjustments totaling $6.9 million and $1.2 million, respectively were made for certain loan pools. These accretable yield adjustments, which are subject to continued re-assessment, will be recognized over the remaining lives of those pools.

The aggregate remaining nonaccretable difference (representing both principal and interest) applicable to acquired loans totaled $8.2 million and $14.6 million at September 30, 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 September 30, 2013.

	Nine Months Ended September 30,

Unfunded commitments on extensions of credit to insiders totaled $2.6 million and $6.9 million at September 30, 2013 and December 31, 2012, respectively.

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 relating to the lease portfolio of BankRI’s subsidiary Macrolease. Historically, delinquency rates for this lease portfolio have been significantly less than 8.0%; the rate at September 30, 2013 was 1.19%. At September 30, 2013, a liability for the recourse obligation was included in the Company’s unaudited consolidated financial statements.

Loans and Leases Pledged as Collateral

At September 30, 2013 and December 31, 2012, respectively, $1.3 billion and $1.5 billion of loans and leases were pledged as collateral for repurchase agreements; municipal deposits; treasury, tax and loan deposits; swap agreements; and FHLBB borrowings. The Company did not have any outstanding FRB borrowings at September 30, 2013 or December 31, 2012.

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 applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are 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 six consecutive months 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 $42.0 million at September 30, 2013, compared to $36.9 million at December 31, 2012. The general portion of the allowance for loan and lease losses increased by $5.1 million during the nine months ended September 30, 2013, in part as a result of growth in the commercial real estate and equipment financing portfolios partially offset by the decrease in the indirect auto portfolios.

Specific Allowance

The specific allowance for loan and lease losses was $1.6 million at September 30, 2013, compared to $1.7 million at December 31, 2012. The specific allowance decreased by $0.1 million during the nine months ended September 30, 2013, largely as a result of a large commercial real estate loan payoff, offset by an increase in specific reserves on the equipment financing portfolio.

Unallocated Allowance

The unallocated allowance for loan and lease losses was $2.8 million at September 30, 2013, compared to $2.6 million at December 31, 2012. The unallocated portion of the allowance for loan and lease losses increased by $0.2 million during the nine months ended September 30, 2013, largely as a result of a change in the mix of the loan portfolio and organic loan growth.

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.

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 relies on payment status 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 Company’s asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned.

6 Rating — Substandard

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

7 Rating — Doubtful

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

8 Rating — Definite Loss

Borrowers deemed incapable of repayment. Loans to such borrowers are considered uncollectable 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 September 30, 2013, loans outstanding in the three classes within this category expressed as a percentage of total loans and leases outstanding were as follows: commercial real estate mortgage loans — 32.6%; multi-family mortgage loans — 13.9%; 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 at December 31, 2012 to

$2.0 million at September 30, 2013 and the increase in originated criticized loans from $8.8 million at December 31, 2012 to $9.5 million at September 30, 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 the finished product. 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 newly constructed product, primarily 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 September 30, 2013, loans and leases outstanding in the three classes within this portfolio expressed as a percent of total loans and leases outstanding were as follows: commercial loans and leases — 9.5%; equipment financing loans — 11.9%; 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 (40.5%) 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.

The factors taken into consideration in establishing the allowance for loan and lease losses for all commercial loan and lease categories included the rate of growth of originated loans and leases outstanding, the entrée into tow-truck lending, the increase in originated loans and leases delinquent over 30 days from $5.8 million at December 31, 2012 to $8.0 million at September 30, 2013, and the decrease in total criticized originated loans and leases from $10.9 million at December 31, 2012 to $8.9 million at September 30, 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. 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 September 30, 2013, indirect automobile loans represented 10.3% of the Company’s total loan and lease portfolio. 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

Table of Contents

Notes to Unaudited Consolidated Financial Statements

At and for the Nine Months Ended September 30, 2013 and 2012

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” above is based on borrower credit scores at the time of loan origination. In the present 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 September 30, 2013 and December 31, 2012, respectively.

Consumer Loans — At September 30, 2013, loans outstanding within the three classes within this portfolio expressed as a percent of total loans and leases outstanding were as follows: residential mortgage loans — 11.9%; home equity loans — 5.9%; 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 September 30, 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 September 30, 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.

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 September 30, 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.

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

(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 September 30, 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 September 30, 2013, the Company had eight interest-rate swaps with an aggregate notional amount of $22.6 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 September 30, 2013, and the effect of the Company’s derivative financial instruments on the unaudited consolidated income statements for the three months and nine months ended September 30, 2013. Asset derivatives and liability derivatives are included in other assets and accrued expenses and other liabilities on the unaudited consolidated balance sheets, respectively. Gains recognized on derivatives are included in fees, charges and other income on the unaudited consolidated income statements.

	At September 30, 2013				Three Months Ended September 30, 2013		Nine Months Ended September 30, 2013
	Asset Derivatives		Liability Derivatives		Gain (Loss) Recognized in Income on Derivatives (1)		Gain (Loss) Recognized in Income on Derivatives (1)
	(In Thousands)
Total derivatives (interest-rate products) not designated as hedging instruments	$	930	$	970	$	1	$	(24	)

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

By using derivative financial instruments, the Company exposes itself to credit risk. Credit risk is the risk of failure by the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative is negative, the Company owes the counterparty and, therefore, it does not possess credit risk. The credit risk in derivative instruments is mitigated by entering into transactions with highly-rated counterparties that management believes to be creditworthy and by limiting the amount of exposure to each counterparty. The estimated net credit risk exposure for derivative financial instruments was less than $0.1 million at both September 30, 2013 and December 31, 2012.

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 $0.5 million and $0.5 million in the normal course of business at September 30, 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, GSE residential MBSs and CMOs, and trust preferred securities, all of which are included in Level 2. Certain fair values are estimated using pricing models (such as pooled trust preferred securities and auction-rate municipal securities) and are included in Level 3.

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

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 September 30, 2013.

	Fair Value		Valuation Technique	Unobservable Input	Range	Weighted Average Discount Rates
	(Dollars in Thousands)
Auction-rate municipals	$	1,774	Discounted cash flow	Discount rate	0-5%	4.9	%

Trust preferred pools	$	1,081	Discounted cash flow	Cumulative default	0-100%	10.5	%
				Cure given deferral/ default	0-15%
				Discount rate	5-30%

The significant unobservable inputs used in the fair value measurement include cumulative defaults and cure given deferrals or defaults. Significant increases (decreases) in deferrals or defaults, in isolation would result in a significantly lower (higher) fair value measurement. Alternatively, significant increases (decreases) in cure rates, in isolation would result in a significantly higher (lower) fair value measurement.

The reconciliation of all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) is as follows:

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, including pricing on recent closed market transactions for

Table of Contents

Notes to Unaudited Consolidated Financial Statements

At and for the Nine Months Ended September 30, 2013 and 2012

loans with similar characteristics, are used as secondary market data, and such loans are classified as Level 2 measurements. When not available, loans are classified as Level 3 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).

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 $4.6 million for the three months ended September 30, 2013, compared to $5.2 million for the three months ended September 30, 2012, representing total effective tax rates of 31.9% and 30.6%, respectively. The increase in the effective federal and state tax rate for the three months ended September 30, 2013 as compared to the three months ended September 30, 2012 is primarily due to a $0.5 million reduction in the $0.6 million rehabilitation tax credits in 2012 related to the construction of the Company’s new Corporate office.

On a year-to-date basis, the Company recorded income tax expense of $15.2 million for the first nine months of 2013, compared to $14.5 million for the first nine months of 2012, representing total effective tax rates of 34.3% and 35.6%, respectively. The decrease in the effective federal and state tax rate for the nine months ended September 30, 2013 as compared to the nine months ended September 30, 2012 is primarily due to the non-deductibility of $1.4 million of the $5.4 million in professional fees incurred in 2012 related to the BankRI acquisition, a $0.3 million increase in tax credits from investments in affordable housing partnerships from $0.6 million for the nine months ended September 2012 to $0.9 million for the nine months ended September 30, 2013, and a $0.3 million tax benefit recognized in 2013 for adjustments to the 2012 tax return. These decreases in the effective tax rate were partially offset by the $0.8 million reduction in rehabilitation tax credits recognized in 2013 as compared to 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 credit, and interest-rate swaps. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received.

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

Commercial and similar letters of credit	228		112
Back-to-back interest-rate swaps	22,619		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 credit 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.

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 47 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 primarily in the New York/New Jersey metropolitan area.

The Company focuses its business efforts on profitably growing its commercial lending businesses, both organically and through acquisitions. The Company’s customer focus, multi-bank structure, and risk management are integral to its organic growth strategy and serve to differentiate the Company from its competitors. As full-service financial institutions, the Banks and their subsidiaries focus 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.

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 a 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 each 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

Table of Contents

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.”

Executive Overview

Growth

Total assets of $5.2 billion at September 30, 2013 increased slightly from $5.1 billion at December 31, 2012, and increased $174.8 million, or 3.5%, from $5.1 billion at September 30, 2012.

The loan and lease portfolio increased $123.8 million, or 3.0%, from $4.2 billion at December 31, 2012 to $4.3 billion at September 30, 2013. The Company’s commercial loan portfolios, which are comprised of commercial real estate loans and commercial loans and leases, continued to exhibit growth. The Company’s commercial loan portfolios, which total $3.1 billion, or 71.7% of total loans and leases at September 30, 2013, increased $231.0 million, or 10.8% on an annualized basis, from $2.9 billion, or 68.2% of total loans and leases at December 31, 2012. Loan growth in the Company’s commercial loan portfolios was offset by a $101.4 million decrease in the indirect automobile portfolio during the same period.

Total deposits of $3.7 billion at September 30, 2013 increased $121.7 million, or 3.4%, from $3.6 billion at December 31, 2012. Core deposits, defined as the sum of demand checking, NOW, money market, and savings accounts, increased at a 9.3% annualized rate during the first nine months of 2013, from $2.6 billion at December 31, 2012 to $2.8 billion at September 30, 2013. The Company’s core deposits increased as a percentage of total deposits from 72.0% at December 31, 2012 to 74.6% at September 30, 2013.

Asset Quality

The ratio of the allowance for loan and lease losses to total loans and leases was 1.08% at September 30, 2013, compared to 0.98% at December 31, 2012. The allowance for loan and lease losses related to originated loans and leases as a percentage of total originated loans and leases was 1.31% at September 30, 2013 as compared with 1.33% at December 31, 2012. The Company continued to employ its historical underwriting methodology throughout the nine-month period ended September 30, 2013 and continued to calculate its allowance for loan and lease losses on a historically consistent basis.

Nonperforming assets at September 30, 2013 totaled $16.7 million or 0.32% 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 September 30, 2013 were $0.6 million, or 0.06% of average loans and leases, compared to 0.15% for the three months ended September 30, 2012.

Capital Strength

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 9.45% at September 30, 2013, compared to 9.44% at December 31, 2012. The ratio of stockholders’ equity to total assets was 11.74% and 11.89% at September 30, 2013 and December 31, 2012, respectively. The Company’s tangible equity ratio was 9.03% and 9.08% at September 30, 2013 and December 31, 2012, respectively.

Net Income

For the three months ended September 30, 2013, the Company reported net income of $9.4 million, or $0.14 per basic share and $0.13 per diluted share, down $2.0 million, or 17.3%, from $11.4 million, or $0.16 per basic and diluted share, for the three months ended September 30, 2012. This decrease in net income is primarily the result of a decrease in net interest income of $3.0 million, a decrease in non-interest income of $0.3 million, offset by a decrease in non-interest expense of $0.9 million and a decrease in provision for income taxes of $0.5 million. For the nine months ended September 30, 2013, the Company reported net income of $27.7 million, or $0.40 per basic and diluted share, up $2.5 million, or 9.7%, from $25.3 million, or $0.36 per basic and diluted share, for the nine months ended September 30, 2012. This increase in net income is primarily the result of a decrease in provision for credit losses of $5.7 million, offset by a decrease in non-interest income of $2.2 million and an increase in provision for income taxes of $0.7 million.

The annualized return on average assets was 0.73% and 0.72% for the three months and nine months ended September 30, 2013, respectively, compared to 0.90% and 0.68% for the three months and nine months ended September 30, 2012, respectively. The annualized return on average stockholders’ equity was 6.15% and 6.01% for the three months and nine months ended September 30, 2013, respectively, compared to 7.53% and 5.63% for the three months and nine months ended September 30, 2012, respectively.

The Company’s operating earnings of $27.7 million, or $0.40 per share for the nine months ended September 30, 2013, decreased $1.5 million, or 5.2% from $29.3 million, or $0.42 per share for the nine months ended September 30, 2012. Operating earnings for the nine months ended September 30, 2012 was adjusted for acquisition-related expenses of $4.0 million (after-tax) associated with the acquisition of Bancorp Rhode Island, Inc. in the first quarter of 2012.

Annualized operating returns on average assets were 0.73% and 0.72%, respectively, for the three months and nine months ended September 30, 2013, compared to 0.90% and 0.79%, respectively, for the three months and nine months ended September 30, 2012. Annualized operating returns on average stockholders’ equity were 6.15% and 6.01%, respectively, for the three months and nine months ended September 30, 2013, compared to 7.53% and 6.52%, respectively, for the three months and nine months ended September 30, 2012.

Net interest margin was 3.56% and 3.68%, respectively, for the three months and nine months ended September 30, 2013, compared to 4.00% and 3.88%, respectively, for the three months and nine months ended September 30, 2012. The yield on interest-earning assets decreased 61 basis points from 4.77% during the third quarter of 2012 to 4.16% during the third quarter in 2013, in large part due to continued rate pressures in the lending market. The decrease in yields on interest-earning assets is offset by a decrease of 17 basis points in the Company’s overall cost of funds, from 0.82% for the three months ended September 30, 2012 to 0.65% for the three months ended September 30, 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.

Provisions for credit losses were $2.7 million and $2.9 million for the three months ended September 30, 2013 and September 30, 2012, respectively. During the nine months ended September 30, 2013 and September 30, 2012, the provisions for credit losses were $7.0 million and $12.8 million, respectively. Of the $12.8 million provision recorded in the third quarter of 2012, $4.2 million was related to two short-term commercial loans made by BankRI shortly after the Company’s acquisition of BankRI.

Non-interest income totaled $3.5 million and $9.9 million, respectively, for the three months and nine months ended September 30, 2013. This compared to $3.8 million and $12.1 million, respectively, for the three months and nine months ended September 30, 2012. The decrease of $0.3 million from three months ended September 30, 2012 to three months ended September 30, 2013 is primarily attributable to increased losses from investments in affordable housing projects of $0.5 million. The decrease of $2.2 million from nine months ended September 30, 2012 to nine months ended September 30, 2013 is, in part, due to increased losses from investment in affordable housing projects of $1.0 million as well as a net gain on sales of securities of $0.8 million in the third quarter of 2012.

Non-interest expense decreased $0.9 million, or 2.9%, from $30.4 million during the three months ended September 30, 2012 to $29.6 million for the three months ended September 30, 2013. Non-interest expense decreased $0.4 million, or 0.4%, from $91.5 million during the nine months ended September 30, 2012 to $91.1 million for the nine months ended September 30, 2013. Many factors contributed to the decreases in these periods, including but not limited to, an increase in compensation and employee benefit expense and occupancy expense, offset by a decrease in professional services expense and FDIC insurance expense. These factors are further discussed under “Results of Operations — Non-Interest Expense” below.

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.

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 related to originated loans and leases as a percentage of originated loans and leases, the efficiency and tangible equity ratios, 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.

Loans and Leases

The Company continues to focus strategically on growing its commercial loan portfolios. To this end, these portfolios increased from $2.9 billion at December 31, 2012 to $3.1 billion at September 30, 2013, and from 68.2% of total loans and leases to 71.6% of total loans and leases during the same period. Concomitantly, the Company has elected to allow the indirect

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, 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

Table of Contents

ability to originate loans depends on the strength of the economy, trends in interest rates, and levels of customer demand and market competition.

Commercial Real Estate Loans

The commercial real estate portfolio of $2.1 billion at September 30, 2013 is composed 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 49.3% of total loans and leases outstanding at September 30, 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 the financial resources of the borrower, the borrower’s experience in owning or managing similar property and the borrower’s payment history with the Company and other financial institutions. Factors considered in evaluating the underlying property include the net operating income of the mortgaged premises before debt service and depreciation, the debt service coverage ratio (the ratio of cash flow before debt service to debt service), the use of conservative capitalization rates, and the ratio of the loan amount to the appraised value. Generally, personal guarantees are obtained from commercial real estate loan borrowers.

Commercial real estate and multi-family mortgage loans are typically originated for terms of five 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.

Over 99% of the commercial real estate loans outstanding at September 30, 2013 were secured by properties located in New England. The commercial real estate portfolio at that date was composed primarily of loans secured by apartment buildings ($595.3 million), office buildings ($474.1 million), retail stores ($419.8 million), industrial properties ($248.7 million) and mixed-use properties ($175.0 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 higher concentration limits than do other commercial credit classes. Risk of loss on a construction loan is largely dependent upon the accuracy of the initial estimate of construction costs, the estimated time to sell or rent the completed property at an adequate price or rate of occupancy, and market conditions. If the estimates and projections prove to be inaccurate, the Company may be confronted with a project which, upon completion, has a value that is insufficient to assure full loan repayment.

Criteria applied in underwriting construction loans for which the primary source of repayment is the sale of the property are different from the criteria applied in underwriting construction loans for which the primary source of repayment is the stabilized cash flow from the completed project. For those loans where the primary source of repayment is from resale of the property, in addition to the normal credit analysis performed for other loans, the Company also analyzes project costs, the attractiveness of the property in relation to the market in which it is located and demand within the market area. For those construction loans where the source of repayment is the stabilized cash flow from the completed project, the Company analyzes not only project costs but also how long it might take to achieve satisfactory occupancy and the reasonableness of projected rental rates in relation to market rental rates.

Commercial Loans and Leases

The commercial loan and lease portfolio of $965.9 million at September 30, 2013 is composed of commercial loans, equipment financing loans and leases and condominium association loans and represented 22.4% of total loans outstanding at September 30, 2013. The Company focuses on making commercial loans in the $1 million to $10 million range.

The Company provides commercial banking services to companies in its market area. Over 99% of the commercial loans outstanding at September 30, 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 Federal Home Loan Bank of Boston (“FHLBB”) index.

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

The Company’s equipment financing divisions focus on market niches in which its lenders have deep experience and industry contacts, and on making loans to customers with business experience. An important part of the Company’s equipment financing loan origination volume comes from equipment manufacturers and existing customers as they expand their operations. The equipment financing portfolio is composed primarily of loans to finance coin-operated laundry, dry cleaning, fitness, and convenience store equipment and most recently, tow trucks. As of September 30, 2013, the balance of loans to finance the tow truck industry had reached $101.6 million. The borrowers are located primarily in the greater New York/New Jersey metropolitan area, 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 ten-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. The size of loan is determined by an analysis of cash flow and other characteristics pertaining to the business and the equipment to be financed, based on detailed revenue and profitability data of similar operations.

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

Indirect Automobile Loans

The indirect automobile loan portfolio of $440.9 million at September 30, 2013 represented 10.3% of total loans outstanding at September 30, 2013. Indirect automobile loans are 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 nine months of 2013, competition for these loans increased significantly as credit unions and large national banks entered indirect automobile lending in a search for additional sources of income. 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.

Indirect automobile loans 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

Table of Contents

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.

The Company’s indirect automobile loan policy limits origination of loans with credit scores of 660 or below to 5% of monthly indirect loan originations. At September 30, 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 749. See the subsection “Results of Operations —Provision for Credit Losses” appearing elsewhere herein 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 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 periodic basis.

Consumer Loans

The consumer loan portfolio of $774.1 million at September 30, 2013 is composed of residential mortgage loans, home equity loans and lines of credit and other consumer loans and represented 18.0% of total loans outstanding at September 30, 2013. The Company focuses its mortgage loans on existing and new customers within its branch networks in its urban and suburban marketplaces in the greater Boston and Providence metropolitan areas.

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

In general, the Company maintains three-, five- and seven-year adjustable-rate mortgage loans and ten-year fixed-rate fully amortizing mortgage loans in its portfolio. Fixed-rate mortgage loans with maturities beyond ten years, such as 15- and 30-year fixed-rate mortgages, are not generally maintained in the Company’s portfolio but are, rather, sold into the secondary market on a servicing-released basis. At September 30, 2013, Brookline Bank and BankRI act as brokers and correspondent lenders in these secondary-market transactions. Loan sales in the secondary market provide funds for additional lending and other banking activities. The Company had $0.2 million and $3.2 million in residential mortgage loans held-for-sale at September 30, 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 including the amount of any existing first mortgage liens.

Other consumer loans have historically been a modest part of the Company’s loan originations. At September 30, 2013, originated other consumer loans equaled $6.1 million or 0.2% of total originated loans outstanding at that date. Equity and debt securities were pledged as collateral for a substantial part of the total of those loans.

Asset Quality

Criticized and Classified Assets

The Company’s management negatively rates certain assets as “other asset especially mentioned (“OAEM”),” “substandard” or “doubtful” based on criteria established under banking regulations. These loans and leases are collectively referred to as “criticized” assets. Loans and leases rated OAEM have potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects of the loan or lease at some future date. Loans and leases rated as substandard are inadequately protected by the payment capacity of the obligor or of the collateral pledged, if any. Substandard loans and leases have a well-defined weakness or weaknesses that jeopardize the liquidation of debt and are characterized by the distinct possibility that the Company will sustain some loss if existing deficiencies are not corrected. At September 30, 2013, the Company had $49.5 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.

Total nonperforming assets, which are composed of nonaccrual loans and leases, other real estate owned and other repossessed assets, decreased from $23.7 million at December 31, 2012 to $16.7 million at September 30, 2013. From December 31, 2012 to September 30, 2013, nonaccrual loans and leases decreased $2.9 million (71.7%) in commercial real estate mortgage, $3.6 million (84.3%) in multi-family mortgage, $0.7 million (13.0%) in commercial and $1.1 million (28.0%) in residential mortgage. The decreases in nonaccrual loans in these categories were partially offset by increases of $0.2 million (6.3%) in equipment financing, $0.1 million (97.0%) in indirect automobile and $1.1 million (151.5%) in home equity. The $2.9 million decrease in commercial real estate nonaccrual loans is the result of three loans paying off during the period ending September 30, 2013. The $3.6 million decrease in multi-family nonaccrual loans is primarily attributed to payoff of two loans and the sale of another in this category. The $0.7 million decrease in commercial is primarily the result of payoff of one loan and charge-off of another loan in this category. The $1.1 million decrease in residential nonaccrual loans is the result of a large loan payoff in this category. The $1.1 million increase in home equity nonaccrual loans is primarily due to five new home equity loans that have been placed on nonaccrual status during the period ending September 30, 2013.

At September 30, 2013, restructured loans of $18.1 million included $6.0 million of commercial real estate mortgage loans, $1.0 million of multi-family mortgage loans, $4.0 million of commercial loans, $3.1 million of equipment financing loans, $3.7 million of residential mortgage loans and $0.3 million of home equity loans. At December 31, 2012, restructured loans of $17.2 million included $5.2 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 that is evaluated collectively, coupled with an analysis of certain loans individually evaluated for impairment. Management continuously evaluates and challenges inputs and assumptions in the allowance for loan and lease loss. During the quarter ended September 30, 2013, the provision was positively impacted by $1.2 million for changes in assumptions directly related to improvements in our credit metrics such as economic conditions and asset quality offset by increases in provision for $0.6 million due to loan growth and $0.7 million for subsequent deterioration in the acquired loan portfolios.

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.

Allowance for loan and lease losses as a percentage of total loans and leases	0.97		%	1.13		%	1.00		%	0.32		%	N/A			0.94		%

The allowance for loan and lease losses was $46.4 million at September 30, 2013 or 1.08% 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 $38.9 million or 0.94% of total loans and leases outstanding at September 30, 2012. The increase in the allowance for loan and lease losses and in the allowance for loan and lease losses as a percentage of total loans and leases from September 30, 2012 to September 30, 2013 is due to additions to the allowance for continued loan growth in the commercial real estate portfolios and an additional allowance in the amount of $1.3 million recorded for subsequent deterioration in certain loan pools within the acquired loan portfolios. The allowance for loan and lease losses related to originated loans and leases represents 1.31%, 1.33% and 1.31% of originated loans and leases at September 30, 2013, December 31, 2012 and September 30, 2012, respectively.

Commercial Real Estate Loans

The allowance for commercial real estate loan losses was $22.5 million at September 30, 2013 or 1.06% of total commercial real estate loans outstanding. 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 an allowance for commercial real estate loan losses of $19.2 million or 0.97% of commercial real estate loans outstanding at September 30, 2012. Specific reserves on commercial real estate loans of $0.3 million were unchanged from December 31, 2012 to September 30, 2013. Excluding balances in acquired loan portfolios, the allowance for commercial real estate loan losses as a percentage of total commercial real estate loans outstanding decreased to 1.33% at September 30, 2013 from 1.37% at December 31, 2012.

The $2.5 million increase in the allowance for commercial real estate loan losses during the first nine months of 2013 was primarily driven by originated loan growth of $206.7 million, or 18.9% on an annualized basis, from December 31, 2012 and the addition of $0.4 million in allowance for post-acquisition deterioration in certain commercial real estate loan and lease portfolios. The ratio of total criticized and classified commercial real estate loans to total commercial real estate loans decreased to 1.37% at September 30, 2013 from 1.81% at December 31, 2012. The ratio of originated commercial real estate loans on nonaccrual to total originated commercial real estate loans decreased to 0.06% at September 30, 2013 from 0.24% at December 31, 2012.

As a percentage of average commercial real estate loans, annualized net charge-offs for the three- and nine-month periods ended September 30, 2013 and September 30, 2012 were negligible. 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 $13.7 million or 1.42% of total commercial loans and leases outstanding at September 30, 2013, as compared to $10.7 million or 1.26% at December 31, 2012. Specific reserves on commercial loans and leases increased from $0.8 million at December 31, 2012 to $1.0 million at September 30, 2013. Excluding balances in acquired loan portfolios, the allowance for commercial loan and lease losses as a percentage of total commercial loans and leases outstanding decreased to 1.64% at September 30, 2013 from 1.66% at December 31, 2012.

The $3.0 million increase in the allowance for commercial loan and lease losses during the first nine months of 2013 was primarily driven by originated loan growth of $173.2 million, or 36.0% on an annualized basis, from December 31, 2012 and the addition of $0.3 million in allowances for post-acquisition deterioration in certain commercial loan and lease portfolios. The ratio of total

Table of Contents

criticized and classified commercial loans and leases to total commercial loans and leases was 2.13% at September 30, 2013 as compared to 2.63% at December 31, 2012 and reflects the resolution of several problem credits in the third quarter of 2013. The ratio of originated commercial loans and leases on nonaccrual to total originated commercial loans and leases decreased to 0.71% at September 30, 2013 from 0.91% at December 31, 2012.

Net charge-offs in the commercial loan and lease portfolio for the three-month periods ended September 30, 2013 and September 30, 2012 were $0.2 million and $1.2 million, respectively. As a percentage of average commercial loans and leases, annualized net charge-offs for the three-month periods ended September 30, 2013 and September 30, 2012 were 0.07% and 0.60%, respectively. Net charge-offs in the commercial loan and lease portfolio for the nine-month periods ended September 30, 2013 and September 30, 2012 were $0.6 million and $4.7 million, respectively. As a percentage of average commercial loans and leases, annualized net charge-offs for the nine-month periods ended September 30, 2013 and September 30, 2012 were 0.14% and 0.85%, respectively. 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 $4.3 million or 0.98% of total indirect automobile loans outstanding at September 30, 2013, compared to $5.3 million or 0.98% of the indirect automobile portfolio outstanding at December 31, 2012. There were no loans individually evaluated for impairment in the indirect automobile portfolio at September 30, 2013. The $1.0 million decrease in the allowance for indirect automobile loan losses was primarily a result of declines in loans outstanding, which decreased $101.4 million from $542.3 million at December 31, 2012 to $440.9 million at September 30, 2013.

The ratio of indirect automobile loans with borrower credit scores below 660 to the total indirect automobile portfolio increased slightly to 3.2% at September 30, 2013 from 3.1% at December 31, 2012. The ratio of indirect automobile loans on nonaccrual to total indirect automobile loans increased slightly to 0.04% at September 30, 2013 compared to 0.02% at December 31, 2012.

Net charge-offs in the indirect automobile portfolio for the three-month periods ended September 30, 2013 and September 30, 2012 were $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 September 30, 2013 and September 30, 2012 were 0.34% and 0.21% respectively, reflecting the favorable trend in credit quality as the portfolio has been allowed to run down. Net charge-offs in the indirect automobile portfolio for the nine-month periods ended September 30, 2013 and September 30, 2012 were $0.8 million and $0.8 million, respectively. As a percentage of average indirect automobile loans, annualized net charge-offs for the nine-month periods ended September 30, 2013 and September 30, 2012 were 0.21% and 0.19%, respectively. 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 $3.1 million or 0.40% of total consumer loans and leases outstanding at September 30, 2013 as compared to $2.5 million or 0.32% at December 31, 2012. The reserve for loans individually evaluated for impairment at September 30, 2013 was $0.3 million on loan balances of $4.3 million, compared to $0.6 million on loan balances of $4.8 million at December 31, 2012. Excluding balances in acquired loan portfolios, the allowance for consumer losses as a percentage of total consumer loans outstanding was 0.50% at September 30, 2013, down from 0.54% at December 31, 2012.

The $0.6 million increase in the allowance for consumer loans during the first nine months of 2013 was primarily driven by the addition of $0.6 million in allowance post-acquisition deterioration in residential loans and home equity loans and lines of credit. The ratio of residential and home equity loans with loan-to-value ratios greater than 80% decreased to 6.45% of total residential and home equity loans at September 30, 2013 from 12.91% at December 31, 2012. The ratio of originated consumer loans on nonaccrual to total originated consumer loans decreased to 0.34% at September 30, 2013 from 0.44% at December 31, 2012. 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 September 30, 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.

Net charge-offs in the consumer portfolio for the three-month periods ended September 30, 2013 and September 30, 2012 were less than $0.1 million in both periods. As a percentage of average consumer loans and leases, annualized net charge-offs for the three-month periods ended September 30, 2013 and September 30, 2012 were 0.03% and 0.05%, respectively. Net charge-offs in the consumer portfolio for the nine-month periods ended September 30, 2013 and September 30, 2012 were $0.2 million and $0.3 million, respectively. As a percentage of average consumer loans and leases, annualized net charge-offs for the nine-month periods ended September 30, 2013 and September 30, 2012 were 0.03% and 0.05%, respectively. See the “Results of Operations—Provision for Credit Losses” section below for additional information.

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. 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 $2.8 million at September 30, 2013, compared to $2.6 million at December 31, 2012.

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

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.

Table of Contents

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. In general, the Company seeks to maintain a high degree of liquidity and targets cash and equivalents and investment securities available-for-sale balances of between 10% and 30% of total assets.

Cash, cash equivalents, and investment securities decreased $22.6 million, or 3.8%, since December 31, 2012. Cash, cash equivalents, and investment securities were 11.0% of total assets at September 30, 2013, compared to 11.6% of total assets at December 31, 2012.

Investment Securities Available-for-Sale and Held-to-Maturity

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

Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with their expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities.

Maturities, calls and principal repayments totaled $108.9 million for the nine months ended September 30, 2013 compared to $158.2 million for the same period in 2012. During the nine months ended September 30, 2013, the Company purchased $124.1 million of available-for-sale securities compared to $251.8 million for the same period in 2012. During the nine months ended September 30, 2013, the Company did not sell any available-for-sale securities. This compared to $157.2 million sales and $0.8 million net realized gains during the nine months ended September 30, 2012.

At September 30, 2013, the fair value of all securities available-for-sale was $480.4 million and carried a total of $8.1 million of net unrealized losses at the end of the quarter, compared to $5.4 million of net unrealized gains at December 31, 2012. Of the $480.4 million in securities available-for-sale at September 30, 2013, $352.3 million, or 73.3%, of the portfolio, had gross unrealized losses of $11.3 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. The shift from an unrealized gain position to an unrealized loss position over the first nine months of 2013 was driven by rising interest rates. Management believes that these negative differences between amortized cost and fair value do not include credit losses, but rather differences in interest rates between the time of purchase and the time of measurement. It is more likely than not that the Company will not sell the securities before recovery, and, as a result, it will recover the amortized cost basis of the securities. As such, management has determined that the securities are not other-than-temporarily impaired at September 30, 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. For additional discussion on how the Company validates fair values provided by the third-party pricing service, see Note 4, “Investment Securities,” of the Company’s 2012 Annual Report on Form 10-K for the fiscal year ended December 31, 2012.

Restricted Equity Securities

Federal Reserve Bank Stock

The Company invests in the stock of the Federal Reserve Bank of Boston, as required by the Banks’ membership in the Federal Reserve System. At September 30, 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 $9.7 million which allows for additional borrowing capacity at each Bank. At September 30, 2013, the Company owned stock in the FHLBB with a carrying value of $50.6 million, which represents a decrease of $1.6 million as compared to December 31, 2012 due to a redemption of excess stock. The FHLBB stated that it remained in compliance with all regulatory capital ratios at September 30, 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 paid in 2012, the Company has made capital expenditures of $24.3 million associated with the rehabilitation of its new headquarters in 2012 and 2013. The project should be completed by year-end with additional costs of approximately $0.5 million.

Core Operating Systems

The Company has also entered into contracts associated with the conversion of its core operating systems. All three Banks have successfully converted to a new core operating system. Brookline Bank and First Ipswich were converted in 2012, while BankRI completed its conversion 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. During the nine months ended September 30, 2013, $4.5 million in conversion-related expenditures have been capitalized.

Total deposits	$	3,737,978	100.0	%	0.50	%	$	3,616,259	100.0	%	0.58	%

Total deposits increased $121.7 million to $3.7 billion at September 30, 2013 compared to $3.6 billion at December 31, 2012. Deposits as percentage of total assets increased slightly from 70.3% at December 31, 2012 to 71.4% at September 30, 2013. During the first nine months of 2013, core deposits increased $182.3 million, or 9.3% on an annualized basis, rising from 72.0% of total deposits at December 31, 2012 to 74.6% of total deposits at September 30, 2013. Certificate of deposit accounts decreased $60.6 million, or 8.0% on an annualized basis, during the first nine months of 2013. Certificates of deposit have also fallen as a percentage of total deposits from 28.0% at December 31, 2012 to 25.4% at September 30, 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 blanket security agreements which require 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 fluctuates from time to time in accordance with the policies of the FHLBB. The Company may also borrow from the Federal Reserve “discount window” on $119.0 million of lines of credit as necessary.

FHLBB borrowings decreased $6.1 million to $784.7 million at September 30, 2013 from the December 31, 2012 balance of $790.9 million. Growth in the deposit base led to a decreased reliance on FHLB borrowings.

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 $16.1 million during the nine months ended September 30, 2013, from $51.0 million to $34.9 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. In the first quarter of 2013, the Company repaid $3.0 million in subordinated debt before the scheduled maturity in 2031 given the fixed, high cost of the borrowing. The remaining two subordinated debentures are summarized below:

The Company’s total stockholders’ equity was $614.8 million at September 30, 2013, a $2.7 million increase compared to $612.1 million at December 31, 2012. The increase reflects net income of $27.7 million for the nine months ended September 30, 2013, offset by dividends paid of $17.9 million in that same period and an unrealized loss on securities available-for-sale of $8.4 million (after-tax). The dividends paid in the third quarter of 2013 represented the Company’s 58th consecutive quarter of dividend payments, and the 46th consecutive quarter in which the Company paid a regular dividend of $0.085.

Stockholders’ equity represented 11.74% of total assets at September 30, 2013, as compared to 11.89% at December 31, 2012. Tangible stockholders’ equity (total stockholders’ equity less goodwill and identified intangible assets, net) represented 9.03% of tangible assets (total assets less goodwill and identified intangible assets, net) at September 30, 2013, as compared to 9.08% at December 31, 2012.

Results of Operations — Comparison of the Three-Month and Nine-Month Periods Ended September 30, 2013 and September 30, 2012

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 period 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” below. Information as to the components of interest income, interest expense and average rates is provided under “Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin” below.

Because the Company’s assets and liabilities are not identical in duration and in repricing dates, the differential between the 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 is based on numerous assumptions and other subjective judgments. See the discussion in “Item 3. Quantitative and Qualitative Disclosures about Market Risk” below.

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

Net Interest Income

Net interest income of $43.4 million for the quarter ended September 30, 2013 decreased $3.0 million, or 6.5%, as compared to the third quarter of 2012. This overall decrease on a quarter-over-quarter basis was a result of decreases in total interest income of $4.6 million, or 8.3%, from $55.4 million at September 30, 2012 to $50.8 million at September 30, 2013, offset by a decrease in interest expense of $1.6 million, or 17.5%, from $9.0 million at September 30, 2012 to $7.4 million at September 30, 2013. Pricing pressures in all lending areas continued through the third quarter of 2013 with decreases in the rates charged on newly originated loans quarter-over-quarter offset by an increase in prepayment penalties as discussed at greater length in “Comparison of the Three-Month and Nine-Month Periods Ended September 30, 2013 and September 30, 2012 — Interest Income — Loans and Leases” below.

As a result, net interest margin of 3.56% in the third quarter of 2013 decreased 44 basis points from 4.00% in the third quarter of 2012. Purchase accounting amortization and accretion of $1.8 million contributed 15 basis points to yields on interest-earning assets during the third quarter of 2013, compared to an additional $4.7 million and 40 basis points in the third quarter of 2012.

The cost of funds (including non-interest-bearing demand checking accounts) declined from 0.82% for the three months ended September 30, 2012 to 0.65% for the three months ended September 30, 2013. The Company’s reduction in interest rates offered on money market accounts and certificates of deposit as well as the reduction in wholesale borrowing costs contributed significantly to the reduction in funding costs, which declined 17 basis points from the three months ended September 30, 2012 to the three months ended September 30, 2013. Purchase accounting amortization and accretion on certificates of deposit and other funding sources of $0.9 million and $1.2 million contributed 7 basis points and 10 basis points to reductions in the costs of funds for the three months ended September 30, 2013 and 2012, respectively.

Net interest income of $132.4 million for the nine months ended September 30, 2013 decreased $0.4 million or 0.3% when compared to the nine months ended September 30, 2012. This overall decrease on a year-over-year basis was a result of a $4.9 million reduction in total interest income, from $160.2 million for the nine months ended September 30, 2012 to $155.3 million for the nine months ended September 30, 2013. The reduction in interest income is partially offset by a decrease in interest expense of $4.5 million, or 16.5% , from $27.4 million at September 30, 2012 to $22.9 million at September 30, 2013.

Net interest margin of 3.68% for the nine months ended September 30, 2013 decreased 20 basis points from 3.88% as compared to the nine months ended September 30, 2012. Purchase accounting amortization and accretion of $6.4 million contributed 18 basis points to yields on interest-earning assets during the first nine months of 2013, compared to an additional $8.8 million and 26 basis points in the first nine months of 2012.

Table of Contents

The cost of funds (including non-interest-bearing demand checking accounts) also declined from 0.86% for the first nine months of 2012 to 0.68% for the first nine months of 2013. The Company’s reduction in interest rates offered on money market accounts, and certificates of deposit as well as the reduction in wholesale borrowing costs contributed significantly to the reduction in funding costs, which declined 18 basis points from the nine months ended September 30, 2012 to the nine months ended September 30, 2013. Purchase accounting amortization and accretion on certificates of deposit and other funding sources of $3.0 million and $3.9 million contributed 8 and 11 basis points to reductions in the costs of funds for the first nine months of 2013 and 2012, respectively.

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. They 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.

Declines in the yields on all but the commercial loan portfolio reflect the high rate of loan refinancings and the intense pricing competition which continues to characterize the Company’s lending markets.

Interest income from loans and leases was $48.5 million for the three months ended September 30, 2013, resulting in a yield on total loans and leases of 4.54%. This compares to $53.3 million of interest on loans and leases and a yield of 5.24% for the three months ended September 30, 2012. The quarter-over-quarter $4.8 million decrease in interest income from loans and leases was due to a $8.0 million rate-related decrease, offset by an increase of $3.3 million due to increased origination volume. Purchase accounting accretion and amortization on acquired loans of $0.9 million contributed 8 basis points to net interest margin during the third quarter of 2013, compared to an additional $3.5 million and 30 basis points in the third quarter of 2012. The third quarter of 2013 also benefited from $0.4 million in prepayment penalties which contributed 4 basis points to net interest margin and in particular, to the yield on commercial loans, compared to $0.9 million and 8 basis points in the third quarter of 2012.

Interest income from loans and leases was $148.5 million for the nine months ended September 30, 2013, resulting in a yield on total loans of 4.72%. This compares to $153.0 million of interest on loans and a yield of 5.15% for the nine months ended September 30, 2012. The $4.5 million decrease in interest income from loans and leases was a result of $15.1 million in interest-rate reductions on loans, offset by an increase of $10.8 million due to volume. Accretion and amortization on acquired loans of $3.4 million contributed 9 basis points to net interest margin during the first nine months of 2013, compared to an additional $4.9 million and 14 basis points in the first nine months of 2012. The the first nine months of 2013 also benefited from $3.0 million in prepayment penalties which contributed 8 basis points to the net interest margin and in particular, to the yield on commercial loans, compared to $1.9 million and 6 basis points during the first nine months of 2012.

The year-over-year decrease in total investment income 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.

Total investment income was $2.4 million for the three months ended September 30, 2013, compared to $2.1 million for the three months ended September 30, 2012, representing an increase of $0.2 million, or 11.2%. The yield on investments increased from 1.48% for the quarter ended September 30, 2012 to 1.58% for the quarter ended September 30, 2013. The $0.2 million year-over-year increase in quarterly interest income on investments was largely volume-driven.

Total investment income was $6.8 million for the nine months ended September 30, 2013 compared to $7.2 million for the nine months ended September 30, 2012, representing a decrease of $0.4 million, or 5.1%. The yield on investments decreased from 1.61% for the nine months ended September 30, 2012 to 1.54% for the nine months ended September 30, 2013. Of the $0.4 million decrease in interest income on investments from the nine months ended September 30, 2012 to the nine months ended September 30, 2013, $0.5 million of increases in volume were offset by $0.8 million of decreases in interest rates as the portfolio replaced higher-yielding securities into the current low-rate environment.

Deposits

Ongoing declines in the interest rates paid on deposits and continued declines in certificate of deposit balances as a percentage of total deposits contributed to reductions in the Company’s overall cost of deposits.

Interest expense on deposits decreased $0.7 million or 13.7% from $5.4 million for the quarter ended September 30, 2012 to $4.6 million for the quarter ended September 30, 2013, largely as a result of decreases in deposit offering rates. As a result, the cost of total interest-bearing deposits decreased from 0.72% during the three months ended September 30, 2012 to 0.60% in the three months ended September 30, 2013. Amortization of purchase accounting adjustments of $0.1 million and $0.3 million improved the Company’s net interest margin 1 basis point and 2 basis points, respectively, in the three months ended September 30, 2013 and 2012.

Similarly, the Company’s year-over-year interest expense on interest-bearing deposits decreased $2.1 million from $16.4 million for the nine months ended September 30, 2012 to $14.2 million for the same period in 2013, largely as a result of reductions in interest rates. The cost of total interest-bearing deposits decreased from 0.74% in the nine months ended September 30, 2012 to 0.63% in the nine months ended September 30, 2013. Amortization of purchase accounting adjustments of $0.3 million and $1.0 million improved the Company’s net interest margin by 1 basis point and 3 basis points, respectively, in the nine months ended September 30, 2013 compared to the nine months ended September 30, 2012.

Borrowed Funds

Interest paid on borrowed funds decreased by $0.8 million, or 23.1% from $3.6 million for the three months ended September 30, 2012 to $2.8 million for the three months ended September 30, 2013. The cost of borrowed funds declined from 1.76% during the three months ended September 30, 2012 to 1.35% for the quarter ended September 30, 2013. Decreases in borrowing rates resulted in a decrease in debt-related interest expenses of $0.9 million. Amortization of purchase accounting adjustments on borrowed funds of $0.8 million and $0.9 million improved the Company’s net interest margin by 7 basis points and 8 basis points, respectively, in the three months ended September 30, 2013 compared to the three months ended September 30, 2012.

Interest paid on borrowed funds decreased by $2.4 million, or 21.6% from $11.1 million for the nine months ended September 30, 2012 to $8.7 million for the nine months ended September 30, 2013. The cost of borrowed funds declined from 1.89% on a period-over-period basis to 1.43% for the nine months ended September 30, 2013. Decreases in borrowing rates resulted in a reduction in debt-related interest expenses of $2.8 million, partially offset by a $0.5 million increase in interest expense due to an increase in the balance of borrowed funds. Amortization of purchase accounting adjustments on borrowed funds of $2.6 million and $2.9 million improved the Company’s net interest margin by 7 basis points and 8 basis points, respectively, in the nine months ended September 30, 2013 compared to the nine months ended 2012.

Table of Contents

The provisions for credit losses for the third quarter of 2013 and 2012 were $2.7 million and $2.9 million, respectively. The provisions for credit losses for the nine months ended September 2013 and 2012 were $7.0 million and $12.8 million, respectively. The $5.7 million period-over-period decrease in the provision for loan and lease losses were due in large part to a $4.2 million provision related to two short-term commercial loans made by BankRI shortly after acquisition in early 2012 and a$1.2 million reduction in general allowance due to improving asset quality and economic metrics. The third quarter 2013 provision for loan and lease losses includes a provision of $0.7 million for post-acquisition deterioration of certain acquired loans and loan pools. 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.

During the nine months ended September 30, 2013, the liability for unfunded credit commitments increased $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 nine months of 2013. No credit commitments were charged off against the liability account in the nine-month periods ended September 30, 2013 or 2012.

Non-Interest Income

Total non-interest income decreased $0.3 million, or 8.8%, from $3.8 million for the three months ended September 30, 2012 to $3.5 million for the three months ended September 30, 2013, and decreased $2.2 million, or 18.0%, from $12.1 million for the nine months ended ended September 30, 2012 to $9.9 million for the nine months ended September 30, 2013. The decrease from the three months ended September 30, 2012 to the three months ended September 30, 2013 is primarily attributable to a $0.5 million increase in loss from investments in affordable housing projects. The decrease from the nine months ended ended September 30, 2012 to the nine months ended September 30, 2013 was due to a $1.0 million increase in loss from investments in affordable housing projects, as well as a $0.8 million reduction in gain on sales of securities.

Fees, charges and other income are the major sources of non-interest income for the Company, and include deposit-related fees, loan-related fees and other service fees. Fees, charges and other income increased $0.2 million, or 4.0%, for the three-month period ended September 30, 2013 as compared to the three-month period ended September 30, 2012. For the three-month period ended September 30, 2013, the Company recorded a $0.2 million recovery of an investment previously written off as other-than-temporary impairment. Fees, charges, and other income decreased $0.3 million, or 3.0%, for the nine-month period ended September 30, 2013 as compared to the nine-month period ended September 30, 2012. The decrease is due in part to a reduction of $0.5 million in loan-related fees, offset by an increase of $0.5 million in deposit-related income from a larger deposit base.

Non-interest expense for the three months ended September 30, 2013 decreased $0.9 million compared to the same period in 2012. The increases of $0.9 million in compensation and employee benefits expense and $0.6 million in occupancy expense were offset by decreases of $0.6 million in professional services expense and $1.3 million in other expenses.

Non-interest expense for the nine months ended September 30, 2013 remained flat as compared to the nine months ended September 30, 2012. The increases of $5.0 million in compensation and employee benefits expense, $1.4 million in occupancy expense and $0.9 million in equipment and data processing expense were offset by a decrease of $6.6 million in professional services expense.

The efficiency ratio increased from 60.63% for the three-month period ending September 30, 2012 to 63.06% for the three-month period ending September 30, 2013, and from 63.15% for the nine-month period ending September 30, 2012 to 64.02% for the nine-month period ending September 30, 2013. These increases are primarily as a result of 2013 costs associated with the Company’s infrastructure build, which is now in its final stage.

Compensation and employee benefit expense for the three months ended September 30, 2013 increased $0.9 million, or 6.3% as compared to the same period in 2012. Comparing the nine-month period ended September 30, 2013 and September 30, 2012, the expense increased $5.0 million, or 11.5%. While there was a $0.6 million reduction in compensation and employee benefit expense related to Supplemental Executive Retirement Plan during the third quarter of 2013, the decrease was offset by increases in expense quarter-over-quarter and year-over-year due to 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.

Occupancy expense for the three months ended September 30, 2013 increased $0.6 million, or 23.9%, as compared to the same period in 2012. Comparing the nine-month period ended September 30, 2013 and September 30, 2012, the expense increased $1.4 million, or 17.9%. The increase in occupancy expense is primarily due to additional expenses for the new corporate headquarters in 2013, additional depreciation expenses from new branches in 2013, and the retirement of certain premises and equipment during the three months ended September 30, 2013.

Equipment and data processing expense remained flat for the three months ended September 30, 2013 as compared to the same period in 2012. Comparing the nine-month period ending September 30, 2013 and September 30, 2012, the expense increased $0.9 million, or 7.6%. Equipment and data processing expenses for the nine months ended September 30, 2013 increased year-over-year largely as a result of upgrades in data processing, purchases of equipment and conversion-related expenses incurred in conjunction with BankRI’s core system conversion.

Table of Contents

Professional services expense for the three months ended September 30, 2013 decreased $0.6 million, or 31.2% as compared to the same period in 2012 as outside consultants were released. Comparing the nine-month period ended September 30, 2013 and September 30, 2012, professional services expense decreased $6.6 million, or 60.3%, largely as a result of the inclusion of $5.4 million of acquisition-related expenses in 2012. Additionally, in 2013, there was a reduction in the costs for professional services for integration, bank charter conversion and infrastructure-related expenses.

Other expense decreased $1.3 million, or 30.7%, from the three months ended September 30, 2012 to the three months ended September 30, 2013. The decrease was due largely to reductions in infrastructure-related costs.

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 $3.7 billion at September 30, 2013, and represented 81.9% of total funding (the sum of total deposits and total borrowings), compared to deposits of $3.6 billion, or 80.9% of total funding, at December 31, 2012. Core deposits, which consist of demand checking, NOW, savings and money market accounts, totaled $2.8 billion at September 30, 2013 and represented 74.6% 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.

Table of Contents

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 $828.8 million at September 30, 2013, representing 18.1% of total funding, compared to $854.0 million, or 19.1% 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 $119.0 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 September 30, 2013, the Company’s total borrowing limit from the FHLBB for advances and repurchase agreements was $1.0 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 September 30, 2013, cash and equivalents and available-for-sale securities totaled $575.8 million, or 11.0% of total assets. This compares to $598.4 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.

Off-Balance-Sheet Financial Instruments

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

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 ALCO 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 September 30, 2013 or December 31, 2012. See Note 8, “Derivatives and Hedging Activities,” to the unaudited consolidated financial statements.

Table of Contents

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.

Income simulation is the primary tool for measuring the interest-rate risk inherent in the Company’s balance sheet at a given point in time by showing the effect on net interest income, over a twelve-month period, of a variety of interest-rate shocks. These simulations take into account repricing, maturity and prepayment characteristics of individual products. The ALCO reviews simulation results to determine whether 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 September 30, 2013.

At September 30, 2013, net interest income simulation indicated that the Company’s exposure to changing interest rates was within established tolerances. 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
	September 30, 2013					December 31, 2012					September 30, 2012
Gradual Change in Interest Rate Levels	Dollar Change			Percent Change		Dollar Change			Percent Change		Dollar Change			Percent Change
	(Dollars in Thousands)
Up 200%	$	1,643		0.91	%	$	1,513		0.86	%	$	2,851		1.65	%
Up 100%	794			0.44	%	713			0.41	%	1,264			0.73	%
Down 100%	(2,426		)	-1.35	%	(39		)	-0.02	%	(44		)	-0.03	%

The Company also uses interest-rate sensitivity “gap” analysis to provide a more general overview of its interest-rate risk profile. At September 30, 2013, the Company’s one-year cumulative gap was a negative $621.6 million, or negative 11.9% of total assets, compared with a negative $502.3 million, or 9.8% of total assets at December 31, 2012 and a negative $486.5 million, or 9.8% of total assets at September 30, 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.

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

EVE at Risk is calculated by estimating the net present value of all future cash flows from existing assets and liabilities using current interest rates as well as parallel shocks to the current interest-rate environment. The following table sets forth the estimated percentage change in the Company’s EVE at Risk, assuming various

shifts in interest rates. Given the interest rate environment at September 30, 2013, simulations for interest rate declines of more than 100 basis points were not deemed to be meaningful.

Up 300%	-7.51	%

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.

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 controls over financial reporting.

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

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

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

There are no material pending legal proceedings other than those that arise in the normal course. In the opinion of management, after consulting with legal counsel, the consolidated financial position and results of operations of the Company are not expected to be affected materially by the outcome of such proceedings.

Item 1A. Risk Factors

In addition to the risk factor discussed below and other information set forth in this report, you should carefully consider the factors discussed in Item 1A of the Company’s Form 10-K for the year ended December 31, 2012.

We will become subject to more stringent capital requirements.

The Dodd-Frank Consumer Protection and Wall Street Reform Act (the “Dodd-Frank Act”) requires the federal banking agencies to establish minimum leverage and risk-based capital requirements for insured banks and their holding companies. The federal banking agencies issued a joint final rule, or the “Final Capital Rule,” that implements the Basel III capital standards and establishes the minimum capital levels required under the Dodd-Frank Act. We must comply with the Final Capital Rule by January 1, 2015. The Final Capital Rule establishes a minimum common equity Tier I capital ratio of 6.5% of risk-weighted assets for a “well-capitalized” institution and increases the minimum Tier I capital ratio for a “well-capitalized” institution from 6% to 8%. Additionally, the Final Capital Rule requires an institution to maintain a 2.5% common equity Tier I capital conservation buffer to avoid restrictions on the ability to pay dividends, discretionary bonuses, and engage in share repurchases. The Final Capital Rule permanently grandfathers trust-preferred securities issued before May 19, 2010 for institutions with less than $15.0 billion in total assets as of December 31, 2009, subject to a limit of 25% of Tier I capital. The Final Capital Rule increases the required capital for certain categories of assets, including high-volatility construction real estate loans and certain exposures related to securitizations; however, the Final Capital Rule retains the current capital treatment of residential mortgages. Under the Final Capital Rule, we may make a one-time, permanent election to continue to exclude accumulated other comprehensive income from capital. If we do not make this election, unrealized gains and losses will be included in the calculation of our regulatory capital. Implementation of these standards, or any other new regulations, may adversely affect our ability to pay dividends, or require us to reduce business levels or raise capital, including in ways that may adversely affect our results of operations or financial condition.
