	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 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 the greater Providence area. First Ipswich, which includes its wholly-owned subsidiaries First Ipswich Securities II Corp. and First Ipswich Insurance Agency, operates 6 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.
	Basis of Financial Statement Presentation
	The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	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 and leases, the review of goodwill and intangibles for impairment and the review of deferred tax assets for valuation allowances.
	The judgments used by management in applying these critical accounting policies may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.
	Reclassification
	Certain previously reported amounts have been reclassified to conform to the current year’s presentation. These reclassifications did not change stockholders' equity and net income reported.

	Recent Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") 2014-04, Receivables-Troubled Debt Restructurings by Creditors. This ASU provides clarification on when an in substance repossession or foreclosure occurs resulting in the creditor derecognizing the loan and recognizing the collateral. Currently, there is no definition of in substance repossession or foreclosure and physical possession in the accounting literature. This ASU is applied retrospectively or effective prospectively for all annual periods presented beginning after December 15, 2014; early adoption is permitted. The Company has not chosen to early adopt ASU 2014-04 and will assess the applicability of this ASU after it becomes effective and as such has not determined the impact, if any, of this ASU.
	In January 2014, the FASB issued ASU 2014-01, Accounting for Investments in Qualified Affordable Housing Projects. This ASU provides guidance on accounting for investments by a reporting entity in flow-through limited liability entities. Currently, investments in qualified affordable housing are accounted for either by the effective yield, equity or cost method. This ASU allows for reporting entities to make a policy election on how to account for their investments. This ASU is applied retrospectively or effective prospectively for all annual periods presented beginning after December 15, 2014; early adoption is permitted. The Company has not chosen to early adopt ASU 2014-01 and will assess the applicability of this ASU after it becomes effective and as such has not determined the impact, if any, of this ASU.

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.
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 March 31, 2014, 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 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 (“FHLMC"), the Government National Mortgage Association (“GNMA”), the Federal Home Loan Banks ("FHLB") and the Federal Farm Credit Bank. At March 31, 2014, only GNMA MBSs and CMOs, and Small Business Administration (“SBA”) commercial loan asset-backed securities with an estimated fair value of $21.3 million were backed explicitly by the full faith and credit of the U.S. Government, compared to $18.9 million at December 31, 2013.
At March 31, 2014, the Company held GSE debentures with a total fair value of $12.1 million and a net unrealized gain of $24.0 thousand. At December 31, 2013, the Company held GSE debentures with a total fair value of $12.2 million and a net unrealized gain of $42.0 thousand. At March 31, 2014, none of the four securities in this portfolio were in unrealized loss positions. At December 31, 2013, none of the five securities in this portfolio was in unrealized loss positions. All securities are performing and backed by the implicit (FHLB / FNMA / FHLMC) or explicit (GNMA / SBA) guarantee of the U.S. Government.
At March 31, 2014, the Company held GSE mortgage-related securities with a total fair value of $466.9 million and a net unrealized loss of $10.3 million. This compares to a total fair value of $443.0 million and a net unrealized gain of $13.8 million at December 31, 2013. At March 31, 2014, 85 of the 237 securities in this portfolio were in unrealized loss positions, compared to 86 of the 232 securities at December 31, 2013. All securities are performing and backed by the implicit (FHLB / FNMA / FHLMC) or explicit (GNMA) guarantee of the U.S. Government. During the three months ended March 31, 2014, the Company purchased $36.5 million in GSE CMOs and GSE MBSs to reinvest cash from matured securities. This compares to a total of $40.0 million during the same period in 2013.
SBA Commercial Loan Asset-Backed
At both March 31, 2014 and December 31, 2013, the Company held nine SBA securities with a total fair value of $0.2 million which approximated amortized cost. At both March 31, 2014 and December 31, 2013, seven of the nine securities in this portfolio were in unrealized loss positions. All securities are performing and backed by the explicit (SBA) guarantee of the U.S. Government.
Private-Label CMOs
At March 31, 2014, the Company held private-issuer CMO-related securities with a total fair value of $3.0 million and a net unrealized gain of $0.1 million. At December 31, 2013, the Company held private-issuer CMO-related securities with a total fair value of $3.4 million and a net unrealized gain of $0.1 million. At March 31, 2014, three of the eleven securities in this portfolio were in unrealized loss positions, compared to two of the eleven securities at December 31, 2013. Full collection of the obligations is expected because the financial condition of the issuers is sound, none of the issuers has defaulted on scheduled payments, the obligations are rated investment grade and the Company has the ability and intent to hold the obligations for a period of time to recover the amortized cost.
Auction-Rate Municipal Obligations and Municipal Obligations
The auction-rate obligations owned by the Company were rated “AAA” at the time of acquisition due, in part, to the guarantee of third-party insurers who would have to pay the obligations if the issuers failed to pay the obligations when they become due. During the financial crisis, certain third-party insurers experienced financial difficulties and were not able to meet their contractual obligations. As a result, auctions failed to attract a sufficient number of investors and created a liquidity problem for those investors who were relying on the obligations to be redeemed at auction. Since then, there has not been an active market for auction-rate municipal obligations.
Based on an evaluation of market factors, the estimated fair value of the auction-rate municipal obligations owned by the Company at March 31, 2014 was $1.7 million, with a corresponding net unrealized loss of $0.2 million. This compares to $1.8 million, with a corresponding net unrealized loss of $0.1 million at December 31, 2013. At March 31, 2014, and December 31, 2013, all of the securities in this 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 amortized cost.
The Company owns municipal obligations with an estimated fair value of $0.3 million which approximated amortized cost at March 31, 2014. This compares to a total fair value of $1.1 million which also approximated amortized cost at December 31, 2013. At March 31, 2014 and December 31, 2013, none of the two securities in this portfolio was 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 amortized cost.
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 fourteen corporate obligation securities with a total fair value of $40.1 million and total net unrealized gains of $0.3 million at March 31, 2014. This compares to eleven corporate obligation securities with a total fair value of $28.2 million and total net unrealized gains of $0.5 million at December 31, 2013. At March 31, 2014 and December 31, 2013, all but one of the securities are investment grade and the non-investment grade security is currently in an unrealized gain position. At March 31, 2014, five of the fourteen securities in this portfolio were in unrealized loss positions. At December 31, 2013, two of the eleven securities in this portfolio are 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 amortized cost.
Trust Preferred Securities
Trust preferred securities represent subordinated debt issued by financial institutions. At March 31, 2014, the Company owned two trust preferred securities with a total fair value of $1.2 million and total net unrealized loss of $0.2 million. This compares to two trust preferred securities with a total fair value of $1.2 million and a total net unrealized loss of $0.3 million at December 31, 2013. At March 31, 2014 and December 31, 2013, all of the securities in this 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 amortized cost.
Marketable Equity Securities
At March 31, 2014, the Company owned marketable equity securities with a fair value of $1.4 million, including net unrealized gains of $0.1 million. This compares to a fair value of $1.3 million and net unrealized gains of $0.1 million at December 31, 2013. At both March 31, 2014 and December 31, 2013, one out of the four securities in this portfolio was in an unrealized loss position.
Investment Securities Held-to-Maturity
In March 2014, a State of Israel bond with a carrying value of $0.5 million and an interest rate payable of LIBOR plus 0.125% matured. The Company then purchased another State of Israel bond in March 2014 with a carrying value of $0.5 million and a fair value of $0.5 million. This security matures in March 2016 and carries an interest rate payable of 1.3%.

Actual maturities of GSE debt securities may differ from those presented above since certain obligations provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty. At March 31, 2014, issuers of debt securities with an estimated fair value of $2.9 million had the right to call or prepay the obligations, the scheduled maturities of which were after ten years. At December 31, 2013, issuers of debt securities with an estimated fair value of $3.7 million had the right to call or prepay the obligations, the scheduled maturities of which were less than one year for $0.7 million , and after ten years for $3.0 million. 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 three-month period ended March 31, 2014 and 2013.

	Accretable Yield for the Acquired Loan Portfolio
	The following table summarizes activity in the accretable yield for the acquired loan portfolio for the periods indicated:
		Three Months Ended March 31,
		2014			2013
		(In Thousands)
	Balance at beginning of period	$	45,789		$	57,812
	Reclassification from nonaccretable difference for loans with improved cash flows	1,440			2,366
	Accretion	(4,728		)	(6,363		)
	Balance at end of period	$	42,501		$	53,815
	On a quarterly basis, subsequent to acquisition, management reforecasts the expected cash flows for acquired ASC 310-30 loans, taking into account prepayment speeds, probability of default and loss given defaults. Management compares cash flow projections per the reforecast to the original cash flow projections and determines whether any reduction in cash flow expectations are due to credit deterioration, or if the change in cash flow is related to noncredit events. This cash flow analysis is used to evaluate the need for a loan loss provision and/or prospective yield adjustments. During the three months ended March 31, 2014 and 2013, accretable yield adjustments totaling $1.4 million and $2.4 million, respectively, were made for certain loan pools. These prospective 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 and leases totaled $4.6 million and $6.1 million at March 31, 2014 and December 31, 2013, respectively.
	Related Party Loans
	The Banks’ authority to extend credit to their respective directors and executive officers, as well as to entities controlled by such persons, is currently governed by the requirements of the Sarbanes-Oxley Act of 2002 and Regulation O of the FRB. Among other things, these provisions require that extensions of credit to insiders (1) be made on terms that are substantially the same as, and follow credit underwriting procedures that are not less stringent than, those prevailing for comparable transactions with unaffiliated persons and that do not involve more than the normal risk of repayment or present other unfavorable features; and (2) not exceed certain limitations on the amount of credit extended to such persons, individually and in the aggregate, which limits are based, in part, on the amount of the Banks’ capital. In addition, the extensions of credit to insiders must be approved by each Bank’s Board of Directors.
	The following table summarizes the change in the total amounts of loans and advances, to directors, executive officers and their affiliates for the periods indicated. All loans were performing at March 31, 2014 and December 31, 2013.

	The liability for unfunded credit commitments, which is included in other liabilities, was $1.1 million, $1.0 million and $0.8 million at March 31, 2014, December 31, 2013 and March 31, 2013, respectively. During the three-month periods ended March 31, 2014 and 2013, the liability for unfunded credit commitments increased by $0.1 million to reflect changes in the estimate of loss exposure associated with credit commitments. No credit commitments were charged off against the liability account in the three-month periods ended March 31, 2014 and 2013.

	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. 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 at least 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 $45.9 million at March 31, 2014, compared to $44.1 million at December 31, 2013. The general portion of the allowance for loan and lease losses increased by $1.8 million during the three months ended March 31, 2014, 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 portfolio.
	Specific Allowance
	The specific allowance for loan and lease losses was $1.3 million at March 31, 2014, compared to $1.5 million at December 31, 2013. The specific allowance decreased by $0.2 million during the three months ended March 31, 2014, largely as a result of improved expected cash flows on several impaired loans and leases.
	Unallocated Allowance
	The unallocated allowance for loan and lease losses was $3.0 million at March 31, 2014, compared to $2.9 million at December 31, 2013. The unallocated portion of the allowance for loan and lease losses increased by $0.1 million during the three months ended March 31, 2014, largely as a result of a change in the mix of the loan portfolio and 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 March 31, 2014, loans outstanding in the three classes within this segment expressed as a percentage of total loans and leases outstanding were as follows: commercial real estate mortgage loans — 33.7%; multi-family mortgage loans — 14.2%; and construction loans — 3.0%.
Loans in this portfolio that are on nonaccrual status and/or risk-rated “substandard” or worse are evaluated on an individual loan basis for impairment. For non-impaired commercial real estate loans, loss factors are applied to outstanding loans by risk rating for each of the three classes in the portfolio. The factors applied are based primarily on historic loan loss experience and an assessment of internal and external factors and other relevant information.
Commercial Loans and Leases — At March 31, 2014, loans and leases outstanding in the three classes within this segment expressed as a percent of total loans and leases outstanding were as follows: commercial loans and leases — 9.8%; 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.
Indirect Automobile Loans — At March 31, 2014, indirect automobile loans represented 8.4% 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 and the following ranges of borrower credit scores: over 700, between 661 and 700, and 660 and below. The Company’s loan policy specifies underwriting guidelines based in part on the score of the borrower and includes ceilings on the percent of loans originated that can be to borrowers with credit scores of 660 and below. The breakdown of the amounts shown in “Credit Quality Information” above is based on borrower credit scores at the time of loan origination. 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 3.1% and 3.2% at March 31, 2014 and December 31, 2013, respectively.
Consumer Loans — At March 31, 2014, loans outstanding within the three classes within this segment expressed as a percent of total loans and leases outstanding were as follows: residential mortgage loans — 11.9%; 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. Consumer loans that become 90 days or more past due, or are placed on nonaccrual regardless of past due status, are reviewed on an individual basis for impairment by assessing the net realizable value of underlying collateral and the economic condition of the borrower.
Impaired Loans and Leases
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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivatives and Hedging Activities	'
	Derivatives and Hedging Activities
	The Company may use interest-rate contracts (swaps, caps and floors) as part of interest-rate risk management strategy. Interest-rate swap, cap and floor agreements are entered into as hedges against future interest-rate fluctuations on specifically identified assets or liabilities. The Company did not have derivative fair value hedges or derivative cash flow hedges at March 31, 2014 or December 31, 2013.
	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. The Company had 8 interest-rate swaps related to this program with an aggregate notional amount of $22.2 million and $22.4 million at March 31, 2014 and December 31, 2013, respectively.
	The table below presents the fair value and classification of the Company’s derivative financial instruments on the consolidated balance sheets at March 31, 2014 and December 31, 2013, and the effect of the Company’s derivative financial instruments on the consolidated statements of income for the three months ended March 31, 2014 and December 31, 2013. Asset derivatives and liability derivatives are included in other assets and accrued expenses and other liabilities on the consolidated balance sheets, respectively. Gains recognized on derivatives are included in non-interest other income on the consolidated statements of income.

	-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 which 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 Company had limited exposure relating to interest rate swaps with institutional counterparties at March 31, 2014 and December 31, 2013, as all such swaps were in a net liability position and subject to master netting agreements.
	The estimated net credit risk exposure for derivative financial instruments was $29.4 thousand and $31.2 thousand at March 31, 2014 and December 31, 2013, respectively.
	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 $2.8 million in the normal course of business at both March 31, 2014 and December 31, 2013.
	The tables below present the offsetting of derivatives and amounts subject to master netting agreements not offset in the unaudited consolidated balance sheet at the dates indicated.

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

	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, GSE residential MBSs and CMOs, private-label CMOs, municipal and corporate debt securities, and trust preferred securities, all of which are included in Level 2. Certain fair values estimated using pricing models (such as auction-rate municipal securities) 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 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 Vehicles and Equipment
Repossessed vehicles and equipment are carried at estimated fair value less costs to sell based on auction pricing (Level 2).
The table below presents quantitative information about significant unobservable inputs (Level 3) for assets measured at fair value on a recurring and non-recurring basis at March 31, 2014.
	Fair Value			Valuation Technique		Unobservable Input	Range		Weighted Average
									Discount Rates
	(Dollars in Thousands)
Auction-rate municipal obligations	$	1,690		Discounted cash flow		Discount rate	0-5%		4.00%
Collateral-dependent impaired loans and leases	$	7,301		Appraisal of collateral (1)
Other real estate owned	$	855		Appraisal of collateral (1)
(1) Fair value is generally determined through independent appraisals of the underlying collateral. The Company may also use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. The valuation generally includes various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.
Discount rate is used as a significant unobservable input to measure the fair value measurement of auction-rate municipal obligations. Significant increases (decreases) in discount rates, in isolation would result in a significantly lower (higher) fair value measurement.
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 Held-for-Sale
Fair value is measured using quoted market prices when available. These assets are typically categorized as Level 1. If quoted market prices are not available, comparable market values may be utilized. These assets are typically categorized as Level 2.
Loans and Leases
The fair values of performing loans and leases 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.
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.

	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.
	Financial instruments with off-balance-sheet risk at the dates indicated follow:
		At March 31, 2014		At December 31, 2013
		(In Thousands)
	Financial instruments whose contract amounts represent credit risk:
	Commitments to originate loans and leases:
	Commercial real estate	$	46,753	$	48,973
	Commercial	132,659		143,252
	Residential mortgage	10,658		8,027
	Unadvanced portion of loans and leases	577,151		586,279
	Unused lines of credit:
	Home equity	207,994		205,665
	Other consumer	6,363		6,503
	Other commercial	1,317		1,035
	Unused letters of credit:
	Financial standby letters of credit	18,685		20,410
	Performance standby letters of credit	2,989		2,989
	Commercial and similar letters of credit	2,316		440
	Back-to-back interest-rate swaps	22,218		22,418
	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.
	The liability for unfunded credit commitments, which is included in other liabilities, was $1.1 million at March 31, 2014 and $1.0 million at December 31, 2013.
	From time to time the Company enters into back-to-back interest rate swaps with commercial customers and third-party financial institutions. These swaps allow the Company to offer long-term fixed-rate commercial loans while mitigating the interest-rate risk of holding those loans. In a back-to-back interest rate swap transaction, the Company lends to a commercial customer on a floating-rate basis and then enters into an interest rate swap with that customer. Concurrently, the Company enters into offsetting swaps with a third-party financial institution, effectively minimizing its net interest-rate risk exposure resulting from such transactions.
	The fair value of interest rate swap assets and liabilities is $0.8 million and $0.8 million, respectively, at March 31, 2014. The fair value of interest rate swap assets and liabilities is $0.8 million and $0.9 million, respectively, at December 31, 2013.
	Lease Commitments
	The Company leases certain office space under various noncancellable operating leases. A summary of future minimum rental payments under such leases at the dates indicated follows:
		Minimum Rental Payments

	2017	3,795
	2018	3,157
	Thereafter	12,277
	Total	$	31,332
	The leases contain escalator clauses for real estate taxes and other expenditures. Total rental expense was $2.3 million during the three months ended March 31, 2014, which included $0.8 million in lease acceleration related to a relocation of an operations center and a closure of a branch property. This compared to $1.3 million during the three months ended March 31, 2013.
	Legal Proceedings
	In the normal course of business, there are various outstanding legal proceedings. In the opinion of management, after consulting with legal counsel, the consolidated financial position and results of operations of the Company are not expected to be affected by the outcome of such proceedings.

	Basis of Financial Statement Presentation
	The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to the rules of the Securities and Exchange Commission (“SEC”) for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	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 and leases, the review of goodwill and intangibles for impairment and the review of deferred tax assets for valuation allowances.
	The judgments used by management in applying these critical accounting policies may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.

[1]	Fair value is generally determined through independent appraisals of the underlying collateral. The Company may also use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. The valuation generally includes various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.
