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 addition 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.

Competition
The Company provides banking alternatives in the greater Boston, Massachusetts, and Providence, Rhode Island, metropolitan marketplaces, each of which is dominated by several large national banking institutions. Based on total deposits at June 30, 2015,2018, the Company ranks eighteenthsixteenth in deposit market share among bank holding companies in the Massachusetts market area and fifth in deposit market share among bank holding companies in the Rhode Island market area. The Company faces considerable competition in its market area for all aspects of banking and related service activities. Competition from both bank and non-bank organizations is expected to continue with the Company facing strong competition in generating loans and attracting deposits.
In addition to other commercial banks, the Company's main competition for generating loans includes savings banks, credit unions, mortgage banking companies, insurance companies, and other financial services companies. Competitive factors considered for loan generation include product offerings, interest rates, terms offered, services provided and geographic locations. Lending services for the Company are concentrated in the greater Boston, Massachusetts, and Providence, Rhode

2


Island, metropolitan areas, eastern Massachusetts, southern New Hampshire, and other Rhode Island areas, while the Company's equipment financing activities are primarily concentrated in the greater New York and New Jersey metropolitan markets.
The Company's primary competitors for attracting deposits are savings banks, commercial banks, credit unions, and other non-depository institutions such as securities and brokerage firms and insurance companies. Competitive factors considered in attracting and retaining deposits include product offerings and rate of return, convenient branch locations and automated teller machines and online access to accounts. Deposit customers are generally in communities where banking offices are located.
Market Area and Credit Risk Concentration
As of December 31, 2015,2018, the Company, through its Banks, operated 4951 full-service banking offices in greater Boston, Massachusetts, and greater Providence, Rhode Island. The Banks' deposits are gathered from the general public primarily in the communities in which the banking offices are located. The deposit market in Massachusetts and Rhode Island is highly concentrated.concentrated in several banks. Based on June 30, 2015 FDIC2018 Federal Deposit Insurance Corporation ("FDIC") statistics, the five largest banks in Massachusetts have an aggregate market share of approximately 66%65%, and the three largest banks in Rhode Island have an aggregate deposit market share of approximately 73%75%. The Banks' lending activities are concentrated primarily in the greater Boston, Massachusetts, and Providence, Rhode Island, metropolitan areas, eastern Massachusetts, southern New Hampshire and other Rhode Island areas. In addition, the Company, through its subsidiaries of Brookline Bank and BankRI, conducts equipment financing activities in the greater New York and New Jersey metropolitan area and elsewhere in the United States.
Commercial real estate loans. Multi-family and commercial real estate mortgage loans typically generate higher yields, but also involve greater credit risk. In addition, many of the Banks' borrowers have more than one multi-family or commercial real estate loan outstanding. The Banks manage this credit risk by prudent underwriting:underwriting with conservative debt service coverage and LTV ratios at origination,origination; lending to seasoned real estate owners/managers,managers; frequently with personal guarantees of repayment; using reasonable capitalization ratios,appraisal practices; cross-collateralizing loans to one borrower when deemed prudent,prudent; and limiting the amount and types of construction lending. As of December 31, 2015,2018, the largest commercial real estate relationship in the Company’s portfolio was $57.0$47.7 million. Many of the Banks’ commercial real estate customers have other commercial borrowing relationships with the Banks.
Commercial loans and equipment leasing. Brookline Bank and First Ipswich originate commercial loans and leases for working capital and other business-related purposes, and concentrate such lending to companies located primarily in Massachusetts, and, in the case of Eastern Funding, in New York and New Jersey. BankRI originates commercial loans and lines of credit for various business-related purposes, for businesses located primarily in Rhode Island, and engages in equipment financing through its wholly-owned subsidiary, Macrolease, in New York and New Jersey.
Because commercial loans are typically made on the basis of the borrower's ability to make repaymentrepay from the cash flow of the business, the availability of funds for the repayment of commercial and industrial loans may be significantly dependent on the success of the business itself. Further, the collateral securing the loans may be difficult to value, may fluctuate in value based on the success of the business and may deteriorate over time. For this reason, these loans and leases involve greater credit risk. Loans and leases originated by Eastern Funding generally earn higher yields because the borrowers are typically small businesses with limited capital such as laundries, dry cleaners, fitness centers, convenience stores and tow truck operators. The Macrolease equipment financing portfolio is comprised of small- to medium-sized businesses such as fitness centers, restaurants and other commercial equipment. The Banks manage the credit risk inherent in commercial lending by requiring strong debt service coverage ratios; limiting loan-to-value ratios; securing personal guarantees from borrowers; and limiting industry concentrations;concentrations, franchisee concentrations and the duration of loan maturities; and employing adjustable rates without interest rate caps.maturities. As of December 31, 2015,2018, the largest commercial relationship in the Company’s portfolio was $21.5$34.1 million.
Indirect auto loans. As of December 2014, Management ceased the origination of indirect automobile loans. Until December 2014, most of Brookline Bank's indirect automobile loans were originated through automobile dealerships located in Massachusetts, Connecticut, Rhode Island and New Hampshire. In March 2015, the Company made the decision and sold $255.2 million of the indirect automobile portfolio. As of December 31, 2015, the largest indirect automobile loan in Brookline Bank's portfolio was $42.0 thousand. For regulatory purposes, Brookline Bank's indirect automobile loan portfolio is not classified as "subprime lending". Prior to Management's decision to cease originating indirect automobile loans, Brookline Bank had in place policies and procedures for loan underwriting and monitoring. Brookline Bank continues to carefully monitor the remaining indirect auto loan portfolio performance and the effect of economic conditions on consumers and the automobile industry. First Ipswich and BankRI do not engage in indirect automobile lending.
Consumer loans. Retail customers of Brookline Bank and First Ipswich typically live and work in the Boston metropolitan area and eastern Massachusetts, are financially active and value personalized service and easy branch access. Retail customers of BankRI typically live and work throughout Rhode Island and value easy branch access, personalized service, and knowledge of local

3


communities. The Banks' consumer loan portfolios, which include residential mortgage loans, home equity loans and lines of credit, and other consumer loans, cater to the borrowing needs of this customer base. Credit risk in these portfolios is managed by limiting loan-to-value ratios at loan origination and by requiring borrowers to demonstrate strong credit histories. As of December 31, 2015,2018, the largest consumer relationship in the Company’s portfolio was $8.3$14.7 million.
Economic Conditions and Governmental Policies
Repayment of multi-family and commercial real estate loans isare generally dependent on the properties generating sufficient income to cover operating expenses and debt service. Repayment of commercial loans and equipment financing loans and leases generally isare dependent on the demand for the borrowers' products or services and the ability of borrowers to compete and operate on a profitable basis. Repayment of residential mortgage loans, home equity loans and indirect automobile loans generally isare dependent on the financial well-being of the borrowers and their capacity to service their debt levels. The asset quality of the Company's loan and lease portfolio, therefore, is greatly affected by the economy.
Economic activity in the United States has shown continuous improvement since the latter half of 2009 after slowing significantly as a result of the 2008 financial crisis. According to the Department of Labor, the national unemployment rate peaked at 10.0% in October 2009. In December 2015,2018, the unemployment rate was 5.0%3.9% nationally, down from 5.6%4.1% at the end of 2014.2017.
The Company's primary geographic footprints are the Boston, Massachusetts, and Providence, Rhode Island, metropolitan areas. According to the Bureau of Labor Statistics, the largest employment sectors in both Massachusetts and Rhode island are, in order: education and health services; business and professional services; and trade;trade, transportation and utilities, a sector that includes wholesale and retail trade. According to the Bureau of Labor Statistics, the largest employment sectors in Rhode Island are, in order: education and health services; trade, transportation and utilities, and business and professional services. The unemployment rate in Massachusetts decreased to 4.7%3.3% in December 20152018 from 5.5%3.5% in December 2014,2017, slightly lower than the national average. The unemployment rate in Rhode Island decreased to 5.1%3.9% in December 20152018 from 6.8%4.4% in December 2014, slightly higher than2017, equal to the national average.
Should there be any setback in the economy or increase in the unemployment rates in the Boston, Massachusetts, or Providence, Rhode Island, metropolitan areas, the resulting negative consequences could affect occupancy rates in the properties financed by the Company and cause certain individual and business borrowers to be unable to service their debt obligations.
The earnings and business of the Company are affected by external influences such as general economic conditions and the policies of governmental authorities, including the Board of Governors of the Federal Reserve System (the "FRB"). The FRB regulates the supply of money and bank credit to influence general economic conditions throughout the United States of America. The instruments of monetary policy employed by the FRB affect interest rates earned on investment securities and loans and interest rates paid on deposits and borrowed funds. The rate-setting actions of the Federal Open Market Committee of the FRB have a significant effect on the Company's operating results and the level of growth in its loans and leases and deposits.
Personnel
As of December 31, 2015,2018, the Company had 675749 full-time employees and 4342 part-time employees. The employees are not represented by a collective bargaining unit and the Company considers its relationship with its employees to be good.

Supervision and Regulation
The following discussion addresses elements of the regulatory framework applicable to bank holding companies and their subsidiaries. This regulatory framework is intended primarily for the protection of the safety and soundness of depository institutions, the federal deposit insurance system, and depositors, rather than for the protection of shareholders of a bank holding company such as the Company.
As a bank holding company, the Company is subject to regulation, supervision and examination by the FRB under the Bank Holding Company Act of 1956, as amended (the “BHCA”), and by the Massachusetts DivisionCommissioner of Banks (the “MDOB”"Commissioner") under Massachusetts General Laws Chapter 167A. The FRB is also the primary federal regulator of the Banks. In addition, Brookline Bank and First Ipswich are subject to regulation, supervision and examination by the MDOB, and BankRI is subject to regulation, supervision and examination by the Banking Division of the Rhode Island Department of Business Regulation (the “RIBD”).
The following is a summary of certain aspects of various statutes and regulations applicable to the Company and its subsidiaries. This summary is not a comprehensive analysis of all applicable law, and is qualified by reference to the applicablefull text of the statutes and regulations.regulations referenced below.
Regulation of the Company
The Company is subject to regulation, supervision and examination by the FRB, which has the authority, among other things, to order bank holding companies to cease and desist from unsafe or unsound banking practices; to assess civil money penalties; and to order termination of non-banking activities or termination of ownership and control of a non-banking subsidiary by a bank holding company.
Source of Strength
Pursuant toUnder the BHCA, as amended by the Dodd-Frank Act, the Company is required to serve as a source of financial strength for the Banks in the event of the financial distress of the Banks. This provision of the Dodd-Frank Act codifies the longstanding policy of the FRB. This support may be required at times when the bank holding company may not have the resources to provide the additional financial support required by its subsidiary banks. In the event of a bank holding company’s bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a bank subsidiary will be assumed by the bankruptcy trustee and entitled to priority of payment.
Acquisitions and Activities
The BHCA prohibits a bank holding company, without prior approval of the FRB, from acquiring all or substantially all the assets of a bank, acquiring control of a bank, merging or consolidating with another bank holding company, or acquiring direct or indirect ownership or control of any voting shares of another bank or bank holding company if, after such acquisition, the acquiring bank holding company would control more than 5% of any class of the voting shares of such other bank or bank holding company. Further, as a Massachusetts bank holding company, the Company generally must obtain the prior approval of the Massachusetts Board of Bank Incorporation to acquire ownership or control of more than 5% of any voting stock in any other banking institution, acquire substantially all the assets of a bank, or merge with another bank holding company. However, there is an exemption from this approval requirement in certain cases in which the banking institution to be acquired,

simultaneously with the acquisition, merges with a banking institution subsidiary of the Company in a transaction approved by the Commissioner.
The BHCA also prohibits a bank holding company from engaging directly or indirectly in activities other than those of banking, managing or controlling banks or furnishing services to its subsidiary banks. However, a bank holding company may engage in and may own shares of companies engaged in certain activities that the FRB determineshas determined to be so closely related to banking or managing and controlling banks as to be a proper incident thereto.
Limitations on Acquisitions of Company Common Stock
The Change in Bank Control Act prohibits a person or group of persons from acquiring “control” of a bank holding company unless the FRB has been notified and has not objected to the transaction. Under a rebuttable presumption established by the FRB, the acquisition of 10% or more of a class of voting securities of a bank holding company, such as the Company, with a class of securities registered under Section 12 of the Exchange Act, would, under the circumstances set forth in the presumption, constitute the acquisition of control of a bank holding company. In addition, the BHCA prohibits any company from acquiring control of a bank or bank holding company without first having obtained the approval of the FRB. Pursuant to the BHCA, a company is deemed to have control of a bank or bank holding company in a number of ways including: if the company owns, controls or holds with power to vote 25% or more of a class of voting securities of the bank or bank holding company; controls in any manner the election of a majority of directors or trustees of the bank or bank holding company; or the

FRB has determined, after notice and opportunity for hearing, that the company has the power to exercise a controlling influence over the management or policies of the bank or bank holding company.
Regulation of the Banks
Brookline Bank and First Ipswich are subject to regulation, supervision and examination by the FRBMDOB and the MDOB.FRB. BankRI is subject to regulation, supervision and examination by the FRBRIBD and the RIBD.FRB. The enforcement powers available to federal and state banking regulators include, among other things, the ability to issue cease and desist or removal orders to terminate insurance of deposits; to assess civil money penalties; to issue directives to increase capital; to place the bank into receivership; and to initiate injunctive actions against banking organizations and institution-affiliated parties.
Deposit Insurance
Deposit obligations of the Banks are insured up to applicable limits by the FDIC’s Deposit Insurance Fund and are subject to deposit insurance assessments to maintain the Deposit Insurance Fund. The Dodd-Frank Act permanently increased the FDIC deposit insurance limitup to $250,000 per separately insured depositor for deposits maintainedheld in the same right and capacity atcapacity. Additionally, Brookline Bank is a particularmember bank of the Depositors Insurance Fund ("DIF"). The DIF is a private, industry-sponsored insurance fund that insures all deposits above FDIC limits for Massachusetts-chartered savings banks. Brookline Bank is also insured depository institution. by the DIF, and as such, Brookline Bank offers 100% insurance on all deposits as a result of a combination of insurance from the FDIC and the DIF. Additionally, Brookline Bank is required to file reports with the DIF.
The Federal Deposit Insurance Act (the “FDIA”), as amended by the Federal Deposit Insurance Reform Act and the Dodd-Frank Act, requires the FDIC to take steps as may be necessary to cause the ratio of deposit insurance reserves to estimated insured deposits - the designated reserve ratio - to reach 1.35% by September 30, 2020, and it mandates that the reserve ratio designated by the FDIC for any year may not be less than 1.35%. The FDIC utilizes a risk-based assessment system that imposes insurance premiums based upon a risk matrix that takes into account a bank’s capital level and supervisory rating (“CAMELS rating”). CAMELS ratings reflect the applicable bank regulatory agencies’ evaluation of the financial institution’s capital, asset quality, management, earnings, liquidity and sensitivity to risk. Assessment rates may also vary for certain institutions based on long-term debt issuer ratings, issuance of unsecured debt and levels of brokered deposits. Pursuant toFurther, the Dodd-Frank Act depositrequired that, in setting assessments, the FDIC offset the effect of the increase in the minimum reserve ratio from 1.15% to 1.35% on banks with less than $10 billion in assets.
To satisfy these requirements, in 2016, the FDIC’s Board of Directors approved a final rule to increase the reserve ratio to the statutorily required minimum ratio of 1.35% of estimated insured deposits. The final rule imposes on large banks a surcharge of 4.5 basis points of their assessment base, after making certain adjustments. Large banks, which are generally banks with $10 billion or more in assets, will pay quarterly surcharges in addition to their regular risk-based assessments. Overall regular risk-based assessment rates will decline once the reserve ratio reaches 1.15%. Small banks, such as the Banks, will receive credits to offset the portion of their assessments that help to raise the reserve ratio from 1.15% to 1.35%. After the reserve ratio reaches 1.38%, the FDIC will automatically apply a small bank’s credits to reduce its regular assessment up to the entire amount of the assessment for each period when the ration is at or above 1.38%.
Deposit premiums are based on assets rather than insurable deposits.assets. To determine their actualits deposit insurance premiums, each ofpremium, the BanksBank computes itsthe base amount onof its average consolidated assets less its average tangible equity (defined as the amount of Tier 1 capital) and itsthe applicable assessment rate. The Company’s FDICIn 2016, the FDIC’s Board of Directors adopted a final rule that changed the manner in which deposit insurance costs totaled $3.5 million in 2015. assessment rates are calculated for established small banks, generally those banks with less than $10 billion of assets that have been insured for at least five years. The rule utilizes the CAMELS rating system, which is a supervisory rating system designed to take into account and reflect all financial and operational risks or bank may face, including capital adequacy, asset

quality, management capability, earnings, liquidity and sensitivity to market risk. Under the final rule, each of seven financial ratios and a weighted average of CAMELS component ratings will be multiplied by a corresponding pricing multiplier. The sum of these products will be added to a uniform amount, with the resulting sum being an institution’s initial base assessment rate (subject to minimum or maximum assessment rates based on a bank’s CAMELS composite rating). This method takes into account various measures, including an institution’s leverage ratio, brokered deposit ratio, one year asset growth, the ratio of net income before taxes to total assets and considerations related to asset quality. Assessments for established small banks with a CAMELS rating of 1 or 2 range from 1.5 to 16 basis points, after adjustments, while assessments for established small banks with a CAMELS rating of 3 range from 3 to 30 basis points. Assessment rates for established small banks with a CAMELS composite rating of 4 or 5 range from 11 to 30 basis points, after adjustments.
The FDIC has the powerauthority to adjust the assessment rates at any time.
Under In addition, under the FDIA, the FDIC may terminate deposit insurance upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC. For 2018, the FDIC and DIF insurance assessment costs for the Company totaled $2.7 million.
Cross-Guarantee
Similar to the source of strength doctrine discussed above in “Regulation of the Company-Source of Strength,” under the cross-guarantee provisions of the FDIA, the FDIC can hold any FDIC-insured depository institution liable for any loss suffered or anticipated by the FDIC in connection with (i) the “default” of a commonly controlled FDIC-insured depository institution; or (ii) any assistance provided by the FDIC to a commonly controlled FDIC-insured depository institution “in danger of default.”
Acquisitions and Branching
The Banks must seek prior regulatory approval from the FRB to acquire another bank or establish a new branch office. Brookline Bank and First Ipswich must also seek prior regulatory approval from the MDOB to acquire another bank or establish a new branch office and BankRI must also seek prior regulatory approval from the RIBD to acquire another bank or establish a new branch office. Well capitalized and well managed banks may acquire other banks in any state, subject to certain deposit concentration limits and other conditions, pursuant to the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994, as amended by the Dodd-Frank Act. In addition, the Dodd-Frank Act authorizes a state-chartered bank to establish new branches on an interstate basis to the same extent a bank chartered by the host state may establish branches.
Activities and Investments of Insured State-Chartered Banks
Section 24 of the FDIA generally limits the types of equity investments that FDIC-insured state-chartered member banks, such as the Banks, may make and the kinds of activities in which such banks may engage, as a principal, to those that are permissible for national banks. Further, the Gramm-Leach-Bliley Act of 1999 (the “GLBA”) permits state banks, to the extent permitted under state law, to engage through “financial subsidiaries” in certain activities which are permissible for subsidiaries of a financial holding company. In order to form a financial subsidiary, a state-chartered bank must be well capitalized, and must comply with certain capital deduction, risk management and affiliate transaction rules, among other requirements.

6


Brokered Deposits
Section 29 of the FDIA and federal regulations generally limit the ability of an insured depository institution to accept, renew or roll over any brokered deposit unless the institution’s capital category is “well capitalized” or, with regulatory approval, “adequately capitalized.” Depository institutions other than those in the lowest risk category, that have brokered deposits in excess of 10% of total depositsassets will be subject to increased FDIC deposit insurance premium assessments. Additionally, depository institutions considered “adequately capitalized” that need regulatory approval to accept, renew or roll over any brokered deposits are subject to additional restrictions on the interest rate they may pay on deposits. As of December 31, 2015,2018, none of the Banks had brokered deposits in excess of 10% of total deposits.
Section 202 of the Economic Growth, Regulatory Relief, and Consumer Protection Act (the "Growth Act"), which was enacted on May 24, 2018, amends Section 29 of the FDIA to exempt a capped amount of reciprocal deposits from treatment as brokered deposits for certain insured depository institutions. Specifically, the Growth Act provides that reciprocal deposits received by an agent depository institution that places deposits (other than those obtained by or though a deposit broker) with a deposit placement network are not considered to be funds obtained by or though a deposit broker to the extent the total amount of such reciprocal deposits does not exceed the lesser of $5 billion or 20% of the depository institution's total liabilities.

However, a depository institution that is less than well capitalized may not accept or roll over such excluded reciprocal deposits at a rate of interest that is significantly higher than the prevailing rate in its market area or a national rate cap established by the FDIC.
The Community Reinvestment Act
The Community Reinvestment Act (“CRA”) requires the FRB to evaluate each of the Banks with regard to their performance in helping to meet the credit needs of the communities each of the Banks serve, including low and moderate-income neighborhoods, consistent with safe and sound banking operations, and to take this record into consideration when evaluating certain applications. The FRB’s CRA regulations are generally based upon objective criteria of the performance of institutions under three key assessment tests: (i) a lending test, to evaluate the institution’s record of making loans in its service areas; (ii) an investment test, to evaluate the institution’s record of investing in community development projects, affordable housing, and programs benefiting low or moderate income individuals and businesses; and (iii) a service test, to evaluate the institution’s delivery of services through its branches, ATMs, and other offices. Failure of an institution to receive at least a “Satisfactory” rating could inhibit the Banks or the Company from undertaking certain activities, including engaging in activities permitted as a financial holding company under GLBA and acquisitions of other financial institutions. Each Bank has achieved a rating of “Satisfactory” on its most recent CRA examination. Both Massachusetts and Rhode Island have adopted specific community reinvestment requirements which are substantially similar to those of the FRB.
Lending Restrictions
Federal law limits a bank’s authority to extend credit to its directors, executive officers and holders ofpersons or companies that own, control or have power to vote more than 10% of the Company's common stock,any class of securities of a bank or an affiliate of a bank, as well as to entities controlled by such persons. Among other things, extensions of credit to insiders are required to 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. Also, the terms of such extensions of credit may not involve more than the normal risk of repayment or present other unfavorable features and may 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 bank’s capital. The Dodd-Frank Act explicitly provides that an extension of credit to an insider includes credit exposure arising from a derivatives transaction, repurchase agreement, reverse repurchase agreement, securities lending transaction or securities borrowing transaction. Additionally, the Dodd-Frank Act requires that asset sale transactions with insiders must be on market terms, and if the transaction represents more than 10% of the capital and surplus of the bank, be approved by a majority of the disinterested directors of the bank.
Capital Adequacy and Safety and Soundness
Regulatory Capital Requirements
The FRB has issued risk-based and leverage capital rules applicable to U.S. banking organizations such as the Company and the Banks. These guidelinesrules are intended to reflect the relationship between the banking organization’s capital and the degree of risk associated with its operations based on transactions recorded on-balance sheet as well as off-balance sheet items. The FRB may from time to time require that a banking organization maintain capital above the minimum levels discussed below, due to the banking organization’s financial condition or actual or anticipated growth.
The capital adequacy rules define qualifying capital instruments and specify minimum amounts of capital as a percentage of assets that banking organizations are required to maintain. Common equity Tier 1 capital generally includes common stock and related surplus, retained earnings and, in certain cases and subject to certain limitations, minority interest in consolidated subsidiaries, less goodwill, other non-qualifying intangible assets and certain other deductions. Tier 1 capital for banks and bank holding companies generally consists of the sum of common equity Tier 1 elements, non-cumulative perpetual preferred stock, and related surplus in certain cases and subject to limitations, minority interests in consolidated subsidiaries that do not qualify as common equity Tier 1 capital, less certain deductions. Tier 2 capital generally consists of hybrid capital instruments, perpetual debt and mandatory convertible debt securities, cumulative perpetual preferred stock, term subordinated debt and intermediate-term preferred stock, and, subject to limitations, allowances for loan losses. The sum of Tier 1 and Tier 2 capital less certain required deductions represents qualifying total risk-based capital. Prior to the effectiveness of certain provisions of the Dodd-Frank Act, bank holding companies were permitted to include trust preferred securities and cumulative perpetual

7


preferred stock in Tier 1 capital, subject to limitations. However, the FRB’s capital rule applicable to bank holding companies permanently grandfathers nonqualifying capital instruments, including trust preferred securities, issued before May 19, 2010 by depository institution holding companies with less than $15 billion in total assets as of December 31, 2009, subject to a limit of 25% of Tier 1 capital. In addition, under rules that became effective January 1, 2015, accumulated other comprehensive income (positive

(positive or negative) must be reflected in Tier 1 capital; however, the Company was permitted to make a one-time, permanent election to continue to exclude accumulated other comprehensive income from capital. The Company has made this election.
Under the capital rules, risk-based capital ratios are calculated by dividing common equity Tier 1, Tier 1, and total risk-basedrisk capital, respectively, by risk-weighted assets. Assets and off-balance sheet credit equivalents are assigned to one of several categories of risk-weights, based primarily on relative risk. Under the FRB's rules, the Company and the Banks are each required to maintain a minimum common equity Tier 1 capital ratio requirement of 4.5%, a minimum Tier 1 capital ratio requirement of 6%, a minimum total capital requirement of 8% and a minimum leverage ratio requirement of 4%. Additionally subject to a transition schedule, these rules require an institution to establish a capital conservation buffer of common equity Tier 1 capital in an amount above the minimum risk-based capital requirements for "adequately capitalized" institutions equal toof more than 2.5% of total risk weighted assets, or face restrictions on the ability to pay dividends, pay discretionary bonuses, and to engaged in share repurchases. The capital conservation buffer was fully phased in as of January 1, 2019.
A bank holding company, such as the Company, is considered "well capitalized" if the bank holding company (i) has a total risk based capital ratio of at least 10%, (ii) has a Tier 1 risk-based capital ratio of at least 6%, and (iii) is not subject to any written agreement order, capital directive or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. In addition, under the FRB's prompt corrective action rules, a state member bank is considered “well capitalized” if it (i) has a total risk-based capital ratio of 10.0% or greater; (ii) a Tier 1 risk-based capital ratio of 8.0% or greater; (iii) a common Tier 1 equity ratio of at least 6.5% or greater, (iv) a leverage capital ratio of 5.0% or greater; and (iv)(v) is not subject to any written agreement, order, capital directive, or prompt corrective action directive to meet and maintain a specific capital level for any capital measure. The FRB also considers: (i) concentrations of credit risk; (ii) interest rate risk; and (iii) risks from non-traditional activities, as well as an institution’s ability to manage those risks. When determining the adequacy of an institution’s capital, this evaluation is a part of the institution’s regular safety and soundness examination. Each of the Banks is currently considered well-capitalized under all regulatory definitions.
Generally, a bank, upon receiving notice that it is not adequately capitalized (i.e., that it is “undercapitalized”), becomes subject to the prompt corrective action provisions of Section 38 of FDIA that, for example, (i) restrict payment of capital distributions and management fees, (ii) require that the FRBits federal bank regulator monitor the condition of the institution and its efforts to restore its capital, (iii) require submission of a capital restoration plan, (iv) restrict the growth of the institution’s assets and (v) require prior regulatory approval of certain expansion proposals. A bank that is required to submit a capital restoration plan must concurrently submit a performance guarantee by each company that controls the bank. A bank that is “critically undercapitalized” (i.e., has a ratio of tangible equity to total assets that is equal to or less than 2.0%) will be subject to further restrictions, and generally will be placed in conservatorship or receivership within 90 days.
The Banks are considered “well capitalized” under the FRB's prompt corrective action rules and the Company is considered “well capitalized” under the FRB's rules applicable to bank holding companies.
Section 201 of the Growth Act directs the federal bank regulatory agencies to establish a community bank leverage ratio of tangible capital to average total consolidated assets of not less than 8% or more than 10%. The legislation provides that a qualifying community bank, which the legislation defines as a depository institution or depository institution holding company with total consolidated assets of less than $10 billion, that exceeds the community bank leverage ratio shall be considered to have met the generally applicable leverage capital requirements and the generally applicable risk-based capital requirements. In addition, a depository institution that exceeds the community bank leverage ratio will be regarded as having met the capital ratio requirements that are required in order to be considered well capitalized under Section 38 of the FDIA. The federal banking agencies may exclude institutions from availing themselves of this relief based on the institution's risk profile, taking into account off-balance sheet exposures, trading assets and liabilities, total notional derivatives exposures, and such other factors as the federal banking agencies determine appropriate. The federal banking agencies have proposed a community bank leverage ratio of 9%, which means that qualifying institutions with a community bank leverage ratio exceeding 9% would be eligible for the relief provided by Section 201 of the Growth Act. The federal banking agencies have also proposed excluding from this relief institutions with levels of off-balance sheet exposures, trading assets and liabilities, mortgage services assets and deferred tax assets exceeding certain levels as well as all advanced approaches banking organizations.
Safety and Soundness Standards
The FDIA requires the federal bank regulatory agencies to prescribe standards, by regulations or guidelines, relating to internal controls, information systems and internal audit systems, risk management, loan documentation, credit underwriting, interest rate risk exposure, asset growth, asset quality, earnings, stock valuation and compensation, fees and benefits, and such other operational and managerial standards as the agencies deem appropriate. Guidelines adopted by the federal bank regulatory agencies establish general standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, asset quality, earnings and compensation, fees and benefits. In general,

these guidelines require, among other things, appropriate systems and practices to identify and manage the risk and exposures specified in the guidelines. The guidelines prohibit excessive compensation as an unsafe and unsound practice and describe compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by an executive officer, employee, director or principal stockholder. In addition, the federal banking agencies adopted regulations that authorize, but do not require, an agency to order an institution that has been given notice by an agency that it is not satisfying any of such safety and soundness standards to submit a compliance plan. If, after being so notified, an institution fails to submit an acceptable compliance plan or fails in any material respect to implement an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order restricting asset growth, requiring an institution to increase its ratio of tangible equity to assets or directing other actions of the types to which an undercapitalized institution is subject under the “prompt corrective action” provisions of FDIA. See “Regulatory Capital Requirements” above. If an institution fails to comply with such an order, the agency may seek to enforce such order in judicial proceedings and to impose civil money penalties.

Dividend Restrictions
The Company is a legal entity separate and distinct from the Banks. The revenue of the Company (on a parent company only basis) is derived primarily from dividends paid to it by the Banks. The right of the Company, and consequently the right of shareholders of the Company, to participate in any distribution of the assets or earnings of the Banks through the payment of such dividends or otherwise is necessarily subject to the prior claims of creditors of the Banks (including depositors), except to the extent that certain claims of the Company in a creditor capacity may be recognized.
Restrictions on Bank Holding Company Dividends
The FRB has authority to prohibit bank holding companies from paying dividends if such payment is deemed to be an unsafe or unsound practice. The FRB has indicated generally that it may be an unsafe or unsound practice for bank holding companies to pay dividends unless the bank holding company’s net income for the prior year is sufficient to fund the dividends and the expected rate of earnings retention is consistent with the organization’s capital needs, asset quality and overall financial condition. Further, under the Federal Reserve's capital rules, the Company's ability to pay dividends will be restricted if it does not maintain the required capital conservation buffer. See “Capital Adequacy and Safety and Soundness-Regulatory Capital Requirements” above.
Restrictions on Bank Dividends
The FRB has the authority to use its enforcement powers to prohibit a bank from paying dividends if, in its opinion, the payment of dividends would constitute an unsafe or unsound practice. Federal law also prohibits the payment of dividends by a bank that will result in the bank failing to meet its applicable capital requirements on a pro forma basis. In addition, a state bank that is a member of the Federal Reserve System may not declare or pay a dividend if the total of all dividends declared during the calendar year, including the proposed dividend, exceeds the sum of the bank's net income (as reportable in its Reports of Condition and Income) during the current calendar year and the retained net income of the prior two calendar years, unless the dividend has been approved by the FRB. A state member bank may not declare and pay a dividend that would exceed its undivided profits (as reportable on its Reports of Condition and Income) unless the dividend has been approved by the FRB. Payment of dividends by a bank is also restricted pursuant to various state regulatory limitations.

Certain Transactions by Bank Holding Companies with their Affiliates
There are various statutory restrictions on the extent to which bank holding companies and their non-bank subsidiaries may borrow, obtain credit from or otherwise engage in “covered transactions” with their insured depository institution subsidiaries. The Dodd-Frank Act amended the definition of affiliate to include an investment fund for which the depository institution or one of its affiliates is an investment adviser. An insured depository institution (and its subsidiaries) may not lend money to, or engage in covered transactions with, its non-depository institution affiliates if the aggregate amount of covered transactions outstanding involving the bank, plus the proposed transaction, exceeds the following limits: (i) in the case of any one such affiliate, the aggregate amount of covered transactions of the insured depository institution and its subsidiaries cannot exceed 10% of the capital stock and surplus of the insured depository institution; and (ii) in the case of all affiliates, the aggregate amount of covered transactions of the insured depository institution and its subsidiaries cannot exceed 20% of the capital stock and surplus of the insured depository institution. For this purpose, “covered transactions” are defined by statute to include a loan or extension of credit to an affiliate, a purchase of or investment in securities issued by an affiliate, a purchase of assets from an affiliate unless exempted by the FRB, the acceptance of securities issued by an affiliate as collateral for a loan or extension of credit to any person or company, the issuance of a guarantee, acceptance or letter of credit on behalf of an affiliate, securities borrowing or lending transactions with an affiliate that creates a credit exposure to such affiliate, or a derivatives transaction with an affiliate that creates a credit exposure to such affiliate. Covered transactions are also subject to certain collateral security requirements. Covered transactions as well as other types of transactions between a bank and a bank holding company must be on market terms and not otherwise unduly favorable to the holding company or an affiliate of the holding company. As of December 31, 2015,2018, there were no such transactions. Moreover, Section 106 of the BHCABank Holding Company Act Amendment of 1970 provides that, to further competition, a bank holding company and its subsidiaries are prohibited from engaging in certain tying arrangements in connection with any extension of credit, lease or sale of property of any kind, or furnishing of any service. As of and for the year ending December 31, 2015,2018, there were no such transactions.
Consumer Protection Regulation
The Company and the Banks are subject to a number of federal and state laws designed to protect consumers and prohibit unfair or deceptive business practices. These laws include the Equal Credit Opportunity Act, Fair Housing Act, Home Ownership Protection Act, Fair Credit Reporting Act, as amended by the Fair and Accurate Credit Transactions Act of 2003 (the “FACT Act”), GLBA, Truth in Lending Act ("TILA"), the CRA, the Home Mortgage Disclosure Act, Real Estate Settlement Procedures Act, National Flood Insurance Act and various state law counterparts. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must interact with customers when taking deposits, making loans, collecting loans and providing other services. Further, the Dodd-Frank Act established the Consumer Financial Protection Bureau ("CFPB"), which has the responsibility for making rules and regulations under the federal consumer protection laws relating to financial products and services. The CFPB also has a broad mandate to prohibit unfair, deceptive or deceptiveabusive acts and practices and is specifically empowered to require certain disclosures to consumers and draft model

9


disclosure forms. Failure to comply with consumer protection laws and regulations can subject financial institutions to enforcement actions, fines and other penalties. The FRB examines the Banks for compliance with CFPB rules and enforceenforces CFPB rules with respect to the Banks.
Mortgage Reform
The Dodd-Frank Act prescribes certain standards that mortgage lenders must consider before making a residential mortgage loan, including verifying a borrower’s ability to repay such mortgage loan, and allows borrowers to assert violations of certain provisions of the Truth-in-Lending ActTILA as a defense to foreclosure proceedings. Under the Dodd-Frank Act, prepayment penalties are prohibited for certain mortgage transactions and creditors are prohibited from financing insurance policies in connection with a residential mortgage loan or home equity line of credit. In addition, the Dodd-Frank Act prohibits mortgage originators from receiving compensation based on the terms of residential mortgage loans and generally limits the ability of a mortgage originator to be compensated by others if compensation is received from a consumer. The Dodd-Frank Act requires mortgage lenders to make additional disclosures prior to the extension of credit, in each billing statement and for negative amortization loans and hybrid adjustable rate mortgages. Additionally, the CFPB’s qualified mortgage rule (the “QM Rule”), requires creditors, such as the Banks, to make a reasonable good faith determination of a consumer's ability to repay any consumer credit transaction secured by a dwelling prior to making the loan. The Growth Act included provisions that ease certain requirements related to mortgage transactions for certain small institutions, which are generally those with less than $10 billion in total consolidated assets.
Privacy and Customer Information Security
The GLBA requires financial institutions to implement policies and procedures regarding the disclosure of nonpublic personal information about consumers to nonaffiliated third parties. In general, the Banks must provide their customers with an annual disclosure that explains their policies and procedures regarding the disclosure of such nonpublic personal information

and, except as otherwise required or permitted by law, the Banks are prohibited from disclosing such information except as provided in such policies and procedures. If the financial institution only discloses information under exceptions from the GLBA that do not require an opt out to be provided and if there has been no change in the financial institutions privacy policies and practices since its most recent disclosures provide to customers, an annual disclosure is not required to be provided by the financial institution. The GLBA also requires that the Banks develop, implement and maintain a comprehensive written information security program designed to ensure the security and confidentiality of customer information (as defined under GLBA), to protect against anticipated threats or hazards to the security or integrity of such information and to protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer. The Banks are also required to send a notice to customers whose “sensitive information” has been compromised if unauthorized use of this information is “reasonably possible.” Most of the states, including the states where the Banks operate, have enacted legislation concerning breaches of data security and the duties of the Banks in response to a data breach. Congress continues to consider federal legislation that would require consumer notice of data security breaches. Pursuant to the FACT Act, the Banks must also develop and implement a written identity theft prevention program to detect, prevent, and mitigate identity theft in connection with the opening of certain accounts or certain existing accounts. Additionally, the FACT Act amends the Fair Credit Reporting Act to generally prohibit a person from using information received from an affiliate to make a solicitation for marketing purposes to a consumer, unless the consumer is given notice and a reasonable opportunity and a reasonable and simple method to opt out of the making of such solicitations.
Anti-Money Laundering
The Bank Secrecy Act
Under the Bank Secrecy Act (“BSA”), a financial institution is required to have systems in place to detect certain transactions, based on the size and nature of the transaction. Financial institutions are generally required to report to the United States Treasury any cash transactions involving more thanat least $10,000. In addition, financial institutions are required to file suspicious activity reports for any transaction or series of transactions that involve more than $5,000 and which the financial institution knows, suspects or has reason to suspect involves illegal funds, is designed to evade the requirements of the BSA or has no lawful purpose. The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the “USA PATRIOT Act”), which amended the BSA, is designed to deny terrorists and others the ability to obtain anonymous access to the U.S. financial system. The USA PATRIOT Act has significant implications for financial institutions and businesses of other types involved in the transfer of money. The USA PATRIOT Act, together with the implementing regulations of various federal regulatory agencies, has caused financial institutions, such as the Banks, to adopt and implement additional policies or amend existing policies and procedures with respect to, among other things, anti-money laundering compliance, suspicious activity, currency transaction reporting, customer identity verification and customer risk analysis. In evaluating an application under Section 3 of the BHCA to acquire a bank or an application under the Bank Merger Act to merge banks or effect a purchase of assets and assumption of deposits and other liabilities, the applicable federal banking

10


regulator must consider the anti-money laundering compliance record of both the applicant and the target. In addition, under the USA PATRIOT Act, financial institutions are required to take steps to monitor their correspondent banking and private banking relationships as well as, if applicable, their relationships with “shell banks.”
Office of Foreign Assets Control (“OFAC”)
The U.S. has imposed economic sanctions that affect transactions with designated foreign countries, nationals and others. These sanctions, which are administered by the U.S. Treasury’s Office of Foreign Assets Control (“OFAC”), take many different forms. Generally, however, they contain one or more of the following elements: (i) restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on “U.S. persons” engaging in financial or other transactions relating to a sanctioned country or with certain designated persons and entities; (ii) a blocking of assets in which the government or specially designated nationals of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction (including property in the possession or control of U.S. persons); and (iii) restrictions on transactions with or involving certain persons or entities. Blocked assets (for example, property and bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Failure to comply with these sanctions could have serious legal and reputational consequences for the Company. As of December 31, 2015,2018, the Company did not have any transactions with sanctioned countries, nationals, and others.

Regulation of Other Activities
Volcker Rule Restrictions on Proprietary Trading and Sponsorship of Hedge Funds and Private Equity Funds
The Dodd-Frank Act prohibits banking organizations such as the Company and the Banks, from engaging in proprietary trading and from sponsoring and investing in hedge funds and private equity funds, except as permitted under certain limited circumstances, in a provision commonly referred to as the “Volcker Rule.” Under the Dodd-Frank Act, proprietary trading generally means trading by a banking entity or its affiliate for its trading account. Hedge funds and private equity funds are described by the Dodd-Frank Act as funds that would be registered under the Investment Company Act but for certain enumerated exemptions. TheSection 203 of the Growth Act includes a provision that excludes a banking organization from application of the Volcker Rule restrictions apply toif the Company, the Banksorganization does not have and allis not controlled by a company that has (i) more than $10 billion in total consolidated assets, and (ii) total trading assets and trading liabilities exceeding 5% of their subsidiaries and affiliates.total consolidated assets.
Item 1A.    Risk Factors
Before deciding to invest in us or deciding to maintain or increase your investment, you should carefully consider the risks described below, in addition to the other information contained in this report and in our other filings with the SEC. The risks and uncertainties described below and in our other filings are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business. If any of these known or unknown risks or uncertainties actually occur, our business, financial condition and results of operations could be seriously harmed. In that event, the market price for our common stock could decline and you may lose your investment.
Deterioration in local economies or real estate market may adversely affect our business.
We primarily serve individuals and businesses located in the greater Boston metropolitan area, eastern Massachusetts, New York, New Jersey, and Rhode Island. Our success is largely dependent on the economic conditions, including employment levels, population growth, income levels, savings trends and government policies, in those market areas. Weaker economic conditions caused by recession, unemployment, inflation, a decline in real estate values or other factors beyond our control may adversely affect the ability of our borrowers to service their debt obligations, and could result in higher loan and lease losses and lower net income for us.
Our business may be adversely affected by conditions in the financial markets and by economic conditions generally.
Weakness in the U.S. economy may adversely affect our business. While in recent years there has been an improvement in the U.S. economy, the outlook remains uncertain amid concerns about short- and long-term interest rates, debt and equity capital markets and financial market conditions generally. A deterioration of business and economic conditions could adversely affect the credit quality of our loans, results of operations and financial condition. Increases in loan delinquencies and default rates could adversely impact our loan charge-offs and provision for loan and lease losses. Deterioration or defaults made by issuers of the underlying collateral of our investment securities may cause additional credit-related other-than-temporary impairment charges to our income statement. Our ability to borrow from other financial institutions or to access the debt or equity capital markets on favorable terms or at all could be adversely affected by disruptions in the capital markets or other events, including actions by rating agencies and deteriorating investor expectations.
Changes to interest rates could adversely affect our results of operations and financial condition.
Our consolidated results of operations depend, on a large part, on net interest income, which is the difference between (i) interest income on interest-earning assets, such as loans, leases and securities, and (ii) interest expense on interest-bearing liabilities, such as deposits and borrowed funds. As a result, our earnings and growth are significantly affected by interest rates, which are subject to the influence of economic conditions generally, both domestic and foreign, to events in the capital markets and also to the monetary and fiscal policies of the United States and its agencies, particularly the FRB. The nature and timing of any changes in such policies or general economic conditions and their effect on us cannot be controlled and are extremely difficult to predict. An increase in interest rates could also have a negative impact on our results of operations by reducing the ability of borrowers to repay their current loan obligations, which could not only result in increased loan defaults, foreclosures and charge-offs, but also necessitate further increases to our allowances for loan losses. A decrease in interest rates may trigger loan prepayments, which may serve to reduce net interest income if we are unable to lend those funds to other borrowers or invest the funds at the same or higher interest rates.
Changes to and replacement of the LIBOR Benchmark Interest Rate may adversely affect our business, financial condition, and results of operations.
In 2017, the United Kingdom’s Financial Conduct Authority (“FCA”), a regulator of financial services firms and financial markets in the United Kingdom, stated that it will plan for a phase out of regulatory oversight of London Interbank Offered

Rate ("LIBOR") interest rate indices. The FCA has indicated that they will support the LIBOR indices through 2021 to allow for an orderly transition to alternative reference rates. Other financial services regulators and industry groups, including the International Swaps and Derivatives Association (“ISDA”), are evaluating the possible phase-out of LIBOR and the development of alternate interest rate indices or reference rates. Accordingly, uncertainty as to the nature of such changes may adversely affect the market for or value of LIBOR-based loans, derivatives, investment securities and other financial obligations held by or due to the Banks, and could adversely impact our financial condition or results of operations.
We operate in a highly regulated industry, and laws and regulations, or changes in them, could limit or restrict our activities and could have ana material adverse impact ineffect on our operations.
We and our banking subsidiaries are subject to regulation and supervision by the FRB. Our banking subsidiaries are also subject to regulation and supervision by state banking regulators and the FRB. Federal and state laws and regulations govern numerous matters affecting us, including changes in the ownership or control of banks and bank holding companies, maintenance of adequate capital and the financial condition of a financial institution, permissible types, amounts and terms of extensions of credit and investments, permissible non-banking activities, the level of reserves against deposits and restrictions on dividend payments. The FRB and the state banking regulators have the power to issue cease and desist orders to prevent or remedy unsafe or unsound practices or violations of law by banks subject to their regulation, and the FRB possesses similar powers with respect to bank holding companies. These and other restrictions limit the manner in which we and our banking subsidiaries may conduct business and obtain financing.
Our business is also affected by the monetary policies of the FRB. Changes in monetary or legislative policies may affect the interest rates that our banking subsidiaries must offer to attract deposits and the interest rates it must charge on loans, as well as the manner in which it offers deposits and makes loans. These monetary policies have had, and are expected to continue to have, significant effects on the operating results of depository institutions generally, including our banking subsidiaries.
As a highly regulated business, the laws, rules, regulations, and supervisory guidance and policies applicable to us are subject to regular modification and change. It is impossible to predict the competitive impact that any such changes would have on the banking and financial services industry in general, or on our business in particular. Such changes may, among other

11


things, increase the cost of doing business, limit permissible activities, or affect the competitive balance between banks and other financial institutions. The Dodd-Frank Act instituted major changes to the banking and financial institutions regulatory regimes in light of government intervention in the financial services sector following the 2008 financial crisis. Other changesChanges to statutes, regulations, or regulatory policies, including changes in interpretation or implementation of statutes, regulations, or policies, or supervisory guidance could affect in enforcement and other legal actions by federal or state authorities, including criminal and civil penalties, the loss of FDIC insurance, revocation of a banking charter, other sanctions by regulatory agencies, civil money penalties, and/or reputational damage, which could have a material adverse effect on our business, financial condition, and results of operations. See the "Supervision and Regulation" section of Item 1, "Business."
We have becomeare subject to more stringent capital requirements.
The federal banking agencies issued a joint final rule, or the “Final Capital Rule,”and liquidity standards that implemented the Basel III capital standards and established the minimum capital levels required under the Dodd-Frank Act. As of January 1, 2015 we are required to comply with the Final Capital Rule. The Final Capital Rule requiresrequire banks and bank holding companies to maintain a minimum common equity Tier 1more and higher quality capital ratio of 4.5% of risk-weighted assets, a minimum Tier 1 capital ratio of 6% of risk-weighted assets, a total capital ratio of 8% of risk-weighted assets, and a leverage ratio of 4%.  In addition, in connection with implementinggreater liquidity than has historically been the Final Capital Rule, the FDIC revised its prompt corrective action regulations for state nonmember banks to require a minimum common equity Tier 1 capital ratio of 6.5% of risk-weighted assets for a “well capitalized” institution and increased the minimum Tier 1 capital ratio for a “well capitalized” institution from 6% to 8%case. Additionally,
We became subject to a transition period, the Final Capital Rule requires banksnew capital requirements in 2015. These new standards, which now apply and are fully phased-in as of January 1, 2019, force bank holding companies and their bank subsidiaries to maintain substantially higher levels of capital as a 2.5%percentage of their assets, with a greater emphasis on common equity Tier 1as opposed to other components of capital. The need to maintain more and higher quality capital, conservation buffer above the minimum risk-basedas well as greater liquidity, and generally increased regulatory scrutiny with respect to capital requirements for adequately capitalized institutions to avoid restrictions on thelevels, may at some point limit our business activities, including lending, and our ability to pay dividends, discretionary bonuses,expand. It could also result in our being required to take steps to increase our regulatory capital and to engage in share repurchases. The Company and the Banks met these requirements as of December 31, 2015. The Final Capital Rule permanently grandfathered trust preferred securities issued before May 19, 2010 for institutions with less than $15 billion in total assets as of December 31, 2009, subject to amay dilute shareholder value or limit of 25% of Tier 1 capital. The Final Capital Rule increased 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 retained the previous capital treatment of residential mortgages. Under the Final Capital Rule, the Company was permitted to make a one-time, permanent election to continue to exclude accumulated other comprehensive income from capital. The Company has made this election. Implementation of these standards, or any other new regulations, may adversely affect our ability to pay dividends or require usotherwise return capital to reduceour investors through stock repurchases.
We are subject to numerous laws designed to protect consumers, including the Community Reinvestment Act and fair lending laws, and failure to comply with these laws could lead to a wide variety of sanctions.
The Community Reinvestment Act, the Equal Credit Opportunity Act, the Fair Housing Act, and other fair lending laws and regulations impose community investment and nondiscriminatory lending requirements on financial institutions. The Consumer Financial Protection Bureau, the Department of Justice and other federal agencies are responsible for enforcing these laws and regulations. A successful regulatory challenge to an institution’s performance under the Community Reinvestment Act, the Equal Credit Opportunity Act, the Fair Housing Act or other fair lending laws and regulations could result in a wide variety of sanctions, including damages and civil money penalties, injunctive relief, restrictions on mergers and acquisitions, restrictions on expansion and restrictions on entering new business levels or raise capital, includinglines. Private parties may also have the ability to challenge an institution’s performance under fair lending laws in ways that may adversely affectprivate class action litigation. Such actions could have a material adverse effect on our business, financial condition and results of operations or financial condition.operations.
We face significant legal risks, both from regulatory investigations and proceedings and from private actions brought against us.
From time to time we are named as a defendant or are otherwise involved in various legal proceedings, including class actions and other litigation or disputes with third parties. There is no assurance that litigation with private parties will not increase in the future. Actions against us may result in judgments, settlements, fines, penalties or other results adverse to us, which could materially adversely affect our business, financial condition or results of operations, or cause serious reputational harm to us. As a participant in the financial services industry, it is likely that we could continue to experience a high level of litigation related to our businesses and operations.

Our businesses and operations are also subject to increasing regulatory oversight and scrutiny, which may lead to additional regulatory investigations or enforcement actions. These and other initiatives from federal and state officials may subject us to further judgments, settlements, fines or penalties, or cause us to be required to restructure our operations and activities, all of which could lead to reputational issues, or higher operational costs, thereby reducing our revenue.
We may incur fines, penalties and other negative consequences from regulatory violations, possibly even inadvertent or unintentional violations.
The financial services industry is subject to intense scrutiny from bank supervisors in the examination process and aggressive enforcement of federal and state regulations, particularly with respect to mortgage-related practices and other consumer compliance matters, and compliance with anti-money laundering, Bank Secrecy Act and Office of Foreign Assets Control regulations, and economic sanctions against certain foreign countries and nationals. Enforcement actions may be initiated for violations of laws and regulations and unsafe or unsound practices. We maintain systems and procedures designed to ensure that we comply with applicable laws and regulations. However,regulations; however, some legal/regulatory frameworks provide for the imposition of fines or penalties for noncompliance even though the noncompliance was inadvertent or unintentional and even though there was in place at the time systems and procedures designed to ensure compliance. For example, we are subjectFailure to comply with these and other regulations, issued by the Office of Foreign Assets Control,and supervisory expectations related thereto, may result in fines, penalties, lawsuits, regulatory sanctions, reputation damage, or “OFAC,” that prohibit financial institutions from participating in the transfer of property belonging to the governments of certain foreign countries and designated nationals of those countries and certain other persons or entities whose interest in property is blocked by OFAC-administered sanctions. OFAC may impose penalties for inadvertent or unintentional violations even if reasonable processes are in place to prevent the violations. There may be other negative consequences resulting from a finding of noncompliance, including restrictions on certain activities. Such a finding may also damage our reputation as described below and could restrict the ability of institutional investment managers to invest in our securities.

Our business may be adversely affected by conditions in the financial markets and by economic conditions generally.
Weakness in the U.S. economy may adversely affect our business. While in recent years there has been a gradual improvement in the U.S. economy, the outlook remains uncertain amid concerns about short- and long-term interest rates, debt and equity capital markets and financial market conditions generally. A deterioration of business and economic conditions could adversely affect the credit quality of our loans, results of operations and financial condition. Increases in loan delinquencies and default rates could adversely impact our loan charge-offs and provision for loan and lease losses. Deterioration or defaults made by issuers of the underlying collateral of our investment securities may cause additional credit-related other-than-temporary impairment charges to our income statement. Our ability to borrow from other financial institutions or to access the debt or equity capital markets on favorable terms or at all could be adversely affected by disruptions in the capital markets or other events, including actions by rating agencies and deteriorating investor expectations.
Deterioration in local economies or real estate market may adversely affect our business.
We primarily serve individuals and businesses located in the greater Boston metropolitan area, eastern Massachusetts, New York, New Jersey, and Rhode Island. Our success is largely dependent on the economic conditions, including employment levels, population growth, income levels, savings trends and government policies, in those market areas. Weaker economic conditions caused by recession, unemployment, inflation, a decline in real estate values or other factors beyond our control may adversely affect the ability of our borrowers to service their debt obligations, and could result in higher loan and lease losses and lower net income for us.
If our allowance for loan and lease losses is not sufficient to cover actual loan and lease losses, our earnings may decrease.
We are exposed to the risk that our borrowers may default on their obligations. A borrower's default on its obligations under one or more loans or leases may result in lost principal and interest income and increased operating expenses as a result of the allocation of management time and resources to the collection and work-out of the loan or lease. In certain situations, where collection efforts are unsuccessful or acceptable work-out arrangements cannot be reached, we may have to write off the loan or lease in whole or in part. In such situations, we may acquire real estate or other assets, if any, that secure the loan or lease through foreclosure or other similar available remedies, and often the amount owed under the defaulted loan or lease exceeds the value of the assets acquired.
We periodically make a determination of an allowance for loan and lease losses based on available information, including, but not limited to, the quality of the loan and lease portfolio as indicated by trends in loan risk ratings, payment performance, economic conditions, the value of the underlying collateral and the level of nonaccruing and criticized loans and leases. Management relies on its loan officers and credit quality reviews, its experience and its evaluation of economic conditions, among other factors, in determining the amount of provision required for the allowance for loan and lease losses. Provisions to this allowance result in an expense for the period. If, as a result of general economic conditions, previously incorrect assumptions, or an increase in defaulted loans or leases, we determine that additional increases in the allowance for loan and lease losses are necessary, additional expenses may be incurred.
Determining the allowance for loan and lease losses inherently involves a high degree of subjectivity and requires us to make significant estimates of current credit risks and trends, all of which may undergo material changes. At any time, there are likely to be loans and/or leases in our portfolio that will result in losses but that have not been identified as nonperforming or potential problem credits. We cannot be sure that we will be able to identify deteriorating credits before they become nonperforming assets or that we will be able to limit losses on those loans and leases that are identified. We have in the past been, and in the future may be, required to increase our allowance for loan and lease losses for any of several reasons. State and federal regulators, in reviewing our loan and lease portfolio as part of a regulatory examination, may request that we increase the allowance for loan and lease losses. Changes in economic conditions or individual business or personal circumstances affecting borrowers, new information regarding existing loans and leases, identification of additional problem loans and leases and other factors, both within and outside of our control, may require an increase in the allowance for loan and lease losses. In addition, if charge-offs in future periods exceed the allowance for loan and lease losses, we will need additional increases in its allowance for loan and lease losses. Any increases in the allowance for loan and lease losses may result in a decrease in our net income and, possibly, our capital, and could have an adverse effect on our financial condition and results of operations.
Our loan and lease portfolios include commercial real estate mortgage loans and commercial loans and leases, which are generally riskier than other types of loans.
Our commercial real estate and commercial loan and lease portfolios currently comprise 80.8% of total loans and leases. Commercial loans and leases generally carry larger balances and involve a higher risk of nonpayment or late payment than residential mortgage loans. Most of the commercial loans and leases are secured by borrower business assets such as accounts receivable, inventory, equipment and other fixed assets. Compared to real estate, these types of collateral are more difficult to monitor, harder to value, may depreciate more rapidly and may not be as readily saleable if repossessed. Repayment of

13


commercial loans and leases is largely dependent on the business and financial condition of borrowers. Business cash flows are

dependent on the demand for the products and services offered by the borrower's business. Such demand may be reduced when economic conditions are weak or when the products and services offered are viewed as less valuable than those offered by competitors. Because of the risks associated with commercial loans and leases, we may experience higher rates of default than if the portfolio were more heavily weighted toward residential mortgage loans. Higher rates of default could have an adverse effect on our financial condition and results of operations.
Environmental liability associated with our lending activities could result in losses.
In the course of business, we may acquire, through foreclosure, properties securing loans originated or purchased that are in default. Particularly in commercial real estate lending, there is a risk that material environmental violations could be discovered on these properties. In this event, we might be required to remedy these violations at the affected properties at our sole cost and expense. The cost of remedial action could substantially exceed the value of affected properties. We may not have adequate remedies against the prior owner or other responsible parties and could find it difficult or impossible to sell the affected properties. These events could have an adverse effect on our financial condition and results of operations.
Competition in the financial services industry could make it difficult for us to sustain adequate profitability.
We face significant competition for loans, leases and deposits from other banks and financial institutions both within and beyond our local marketplace. Many of our competitors have substantially greater resources and higher lending limits than we do and may offer products and services that we do not, or cannot, provide. There is also increased competition by out-of-market competitors through the internet. The ability of non-banking financial institutions to provide services previously limited to commercial banks has intensified competition. Because non-banking financial institutions are not subject to the same regulatory restrictions as banks and bank holding companies, they can often operate with greater flexibility and lower cost structures. Securities firms and insurance companies that elect to become financial holding companies may acquire banks and other financial institutions. This may significantly change the competitive environment in which we conduct our business. As a result of these various sources of competition, we could lose business to competitors or could be forced to price products and services on less advantageous terms to retain or attract clients, either of which would adversely affect our profitability.
Market changes may adversely affect demand for our services and impact results of operations.
Channels for servicing our customers are evolving rapidly, with less reliance on traditional branch facilities, more use of online and mobile banking, and increased demand for universal bankers and other relationship managers who can service multiples product lines. We compete with larger providers who are rapidly evolving their service channels and escalating the costs of evolving the service process. We have a process for evaluating the profitability of our branch system and other office and operational facilities. The identification of unprofitable operations and facilities can lead to restructuring charges and introduce the risk of disruptions to revenues and customer relationships.
Changes to interest rates could adversely affect our results of operations and financial condition.
Our consolidated results of operations depend, on a large part, on net interest income, which is the difference between (i) interest income on interest-earning assets, such as loans, leases and securities, and (ii) interest expense on interest-bearing liabilities, such as deposits and borrowed funds. As a result, our earnings and growth are significantly affected by interest rates, which are subject to the influence of economic conditions generally, both domestic and foreign, to events in the capital markets and also to the monetary and fiscal policies of the United States and its agencies, particularly the FRB. The nature and timing of any changes in such policies or general economic conditions and their effect on us cannot be controlled and are extremely difficult to predict. An increase in interest rates could also have a negative impact on our results of operations by reducing the ability of borrowers to repay their current loan obligations, which could not only result in increased loan defaults, foreclosures and charge-offs, but also necessitate further increases to our allowances for loan losses. A decrease in interest rates may trigger loan prepayments, which may serve to reduce net interest income if we are unable to lend those funds to other borrowers or invest the funds at the same or higher interest rates.
Our securities portfolio performance in difficult market conditions could have adverse effects on our results of operations.
Unrealized losses on investment securities result from changes in credit spreads and liquidity issues in the marketplace, along with changes in the credit profile of individual securities issuers. Under GAAP, we are required to review our investment portfolio periodically for the presence of other-than-temporary impairment of our securities, taking into consideration current market conditions, the extent and nature of changes in fair value, issuer rating changes and trends, volatility of earnings, current analysts' evaluations, our ability and intent to hold investments until a recovery of fair value, as well as other factors. Adverse developments with respect to one or more of the foregoing factors may require us to deem particular securities to be other-than-temporarily impaired, with the credit-related portion of the reduction in the value recognized as a charge to our earnings.

14


Subsequent valuations, in light of factors prevailing at that time, may result in significant changes in the values of these securities in future periods. Any of these factors could require us to recognize further impairments in the value of our securities portfolio, which may have an adverse effect on our results of operations in future periods.
Potential downgrades of U.S. government securities by one or more of the credit ratings agencies could have a material adverse effect on our operations, earnings and financial condition.
A possible future downgrade of the sovereign credit ratings of the U.S. government and a decline in the perceived creditworthiness of U.S. government-related obligations could impact our ability to obtain funding that is collateralized by affected instruments, as well as affect the pricing of that funding when it is available. A downgrade may also adversely affect the market value of such instruments. We cannot predict if, when or how any changes to the credit ratings or perceived creditworthiness of these organizations will affect economic conditions. Such ratings actions could result in a significant adverse impact on us. Among other things, a downgrade in the U.S. government’s credit rating could adversely impact the value of our securities portfolio and may trigger requirements that the Company post additional collateral for trades relative to these securities. A downgrade of the sovereign credit ratings of the U.S. government or the credit ratings of related institutions,

agencies or instruments would significantly exacerbate the other risks to which we are subject and any related adverse effects on the business, financial condition and results of operations.
Wholesale funding sources may prove insufficient to replace deposits at maturity and support our operations and future growth.
We and our banking subsidiaries must maintain sufficient funds to respond to the needs of depositors and borrowers. To manage liquidity, we draw upon a number of funding sources in addition to core deposit growth and repayments and maturities of loans and investments. These sources include Federal Home Loan Bank advances, proceeds from the sale of investments and loans, and liquidity resources at the holding company. Our ability to manage liquidity will be severely constrained if we are unable to maintain access to funding or if adequate financing is not available to accommodate future growth at acceptable costs. In addition, if we are required to rely more heavily on more expensive funding sources to support future growth, our revenues may not increase proportionately to cover our costs. In this case, operating margins and profitability would be adversely affected. Turbulence in the capital and credit markets may adversely affect our liquidity and financial condition and the willingness of certain counterparties and customers to do business with us.
Potential deterioration in the performance or financial position of the FHLBB might restrict our funding needs and may adversely impact our financial condition and results of operations.
Significant components of our liquidity needs are met through our access to funding pursuant to our membership in the FHLBB. The FHLBB is a cooperative that provides services to its member banking institutions. The primary reason for joining the FHLBB is to obtain funding. The purchase of stock in the FHLBB is a requirement for a member to gain access to funding. Any deterioration in the FHLBB’s performance or financial condition may affect our ability to access funding and/or require the Company to deem the required investment in FHLBB stock to be impaired. If we are not able to access funding through the FHLBB, we may not be able to meet our liquidity needs, which could have an adverse effect on our results of operations or financial condition. Similarly, if we deem all or part of our investment in FHLBB stock impaired, such action could have an adverse effect on our financial condition or results of operations.
The soundness of other financial institutions could adversely affect us.
Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions.  Financial services institutions are interrelated as a result of trading, clearing, counterparty and other relationships.  We have exposure to many different counterparties, and we routinely execute transactions with counterparties in the financial industry, including brokers and dealers, other commercial banks, investment banks, mutual and hedge funds, and other financial institutions.  As a result, defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, could lead to market-wide liquidity problems and losses or defaults by us or by other institutions and organizations.  Many of these transactions expose us to credit risk in the event of default of our counterparty or client.  In addition, our credit risk may be exacerbated when the collateral held by us cannot be liquidated or is liquidated at prices not sufficient to recover the full amount of the financial instrument exposure due to us.  There is no assurance that any such losses would not materially and adversely affect our results of operations.
Loss of deposits or a change in deposit mix could increase our cost of funding.
Deposits are a low cost and stable source of funding. We compete with banks and other financial institutions for deposits. Funding costs may increase if we lose deposits and are forced to replace them with more expensive sources of funding, if clients shift their deposits into higher cost products or if we need to raise interest rates to avoid losing deposits. Higher funding costs reduce our net interest margin, net interest income and net income.
Damage to our reputation could significantly harm our business, including our competitive position and business prospects.
We are dependent on our reputation within our market area, as a trusted and responsible financial company, for all aspects of our relationships with customers, employees, vendors, third-party service providers, and others, with whom we conduct business or potential future business. Our ability to attract and retain customers and employees could be adversely affected if our reputation is damaged. Our actual or perceived failure to address various issues could give rise to reputational risk that could cause harm to us and our business prospects. These issues also include, but are not limited to, legal and regulatory requirements; properly maintaining customer and employee personal information; record keeping; money-laundering; sales and trading practices; ethical issues; appropriately addressing potential conflicts of interest; and the proper identification of the legal, reputational, credit, liquidity and market risks inherent in our products. Failure to appropriately address any of these issues could also give rise to additional regulatory restrictions and legal risks, which could, among other consequences, increase the size and number of litigation claims and damages asserted or subject us to enforcement actions, fines and penalties and incur related costs and expenses.

Our ability to service our debt and pay dividends is dependent on capital distributions from our subsidiary banks, and these distributions are subject to regulatory limits and other restrictions.
We are a legal entity that is separate and distinct from the Banks. Our revenue (on a parent company only basis) is derived primarily from dividends paid to us by the Banks. Our right, and consequently the right of our shareholders, to participate in any distribution of the assets or earnings of the Banks through the payment of such dividends or otherwise is necessarily subject to the prior claims of creditors of the Banks (including depositors), except to the extent that certain claims of ours in a creditor capacity may be recognized. It is possible, depending upon the financial condition of our subsidiary banks and other factors, that applicable regulatory authorities could assert that payment of dividends or other payments is an unsafe or unsound practice. If one or more of our subsidiary banks is unable to pay dividends to us, we may not be able to service our debt or pay dividends on our common stock. Further, as a result of the capital conservation buffer requirement of the Final Capital Rule, our ability to pay dividends on our common stock or service our debt could be restricted if we do not maintain a capital conservation buffer. A reduction or elimination of dividends could adversely affect the market price of our common stock and would adversely affect our business, financial condition, results of operations and prospects. See Item 1, “Business-Supervision and Regulation-Dividend Restrictions” and “Business-Supervision and Regulation-Capital Adequacy and Safety and Soundness-Regulatory Capital Requirements.”

To the extent that we acquire other companies, our business may be negatively impacted by certain risks inherent with such acquisitions.
We have acquiredface continuing and will continue to consider the acquisition of other financial services companies. To the extent that we acquire other companies in the future, our business may be negatively impacted by certain risks inherent with such acquisitions. Some of these risks include the following:
The risk that the acquired business will not perform in accordance with Management's expectations;
The risk that difficulties will arise in connection with the integration of the operations of the acquired business with the operations of our businesses;
The risk that Management will divert its attention from other aspects of our business;
The risk that we may lose key employees of the combined business; and
The risks associated with entering into geographic and product markets in which we have limited or no direct prior experience.
We may be required to write down goodwill and other acquisition-related identifiable intangible assets.
When we acquire a business, a portion of the purchase price of the acquisition may be allocated to goodwill and other identifiable intangible assets. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets acquired determines the amount of the purchase price that is allocated to goodwill acquired. As of December 31, 2015, goodwill and other identifiable intangible assets were $148.5 million. Under current accounting guidance, if we determine that goodwill or intangible assets are impaired, we would be required to write down the value of these assets. We conduct an annual review to determine whether goodwill and other identifiable intangible assets are impaired. We conduct a quarterly review for for indicators of impairment of goodwill and other identifiable intangible assets. The Company's Management recently completed these reviews and concluded that no impairment charge was necessary for the year ended December 31, 2015. We cannot provide assurance whether we will be required to take an impairment charge in the future. Any impairment charge would have a negative effect on stockholders' equity and financial results and may cause a decline in our stock price.
Systems failures, interruptions or breaches of security and other cybergrowing security risks could have an adverse effect onto our financial condition and resultsinformation base, including the information we maintain relating to our customers.
In the ordinary course of operations.
We are subject to certain operational risks, including, but not limited to, data processing system failures and errors, cyber security breaches, inadequate or failed internal processes, customer or employee fraud and catastrophic failures resulting from terrorist acts or natural disasters.  We depend upon data processing, software, communication, and information exchange on a variety of computing platforms and networks and over the Internet, andbusiness, we rely on electronic communications and information systems to conduct our business and to store sensitive data, including financial information regarding customers. Our electronic communications and information systems infrastructure, as well as the servicessystems infrastructures of a variety ofthe vendors we use to meet our data processing and communication needs.  Despite instituted safeguards, we cannotneeds, could be certain that allsusceptible to cyber-attacks, such as denial of our systems are entirely free from vulnerability to attackservice attacks, hacking, terrorist activities or identity theft. Financial services institutions and companies engaged in data processing have reported breaches in the security of their websites or other technological difficultiessystems, some of which have involved sophisticated and targeted attacks intended to obtain unauthorized access to confidential information, destroy data, disable or failures. Information security risks have increased significantly due todegrade service or sabotage systems, often through the useintroduction of online, telephone and mobile banking channels by clients and the increased sophistication and activities of organized crime, hackers, terroristscomputer viruses or malware, cyber-attacks and other external parties. Our technologies, systems, networks and our clients’ devicesmeans. Denial of service attacks have been subjectlaunched against a number of large financial services institutions. Hacking and identity theft risks, in particular, could cause serious reputational harm. Cyber threats are rapidly evolving and we may not be able to and are likelyanticipate or prevent all such attacks. Although to continuedate we have not experienced any material losses relating to be the target of, cyber-attacks computer viruses, malicious code, phishing attacks or other information security breaches, there can be no assurance that could resultwe will not suffer such losses in the unauthorized release, gathering, monitoring, misuse, lossfuture. No matter how well designed or destructionimplemented our controls are, we will not be able to anticipate all security breaches of these types, and we may not be able to implement effective preventive measures against such security breaches in a timely manner. A failure or circumvention of our or our clients’ confidential, proprietary and other information, the theft of client assets through fraudulent transactions or disruption of our or our clients’ or other third parties’ business operations. If information security is breached or other technology difficulties or failures occur, information may be lost or misappropriated, and services and operations may be interrupted. A security breach could result in violations of applicable privacy and other laws, financial loss to us or to our customers, loss of confidence in our security measures, significant litigation exposure, and harm to our reputation. While we maintain a system of internal controls and procedures, any of these resultssystems could have a material adverse effect on our business operations and financial condition.
We regularly assess and test our security systems and disaster preparedness, including back-up systems, but the risks are substantially escalating. As a result, cyber-security and the continued enhancement of our controls and processes to protect our systems, data and networks from attacks, unauthorized access or significant damage remain a priority. Accordingly, we may be required to expend additional resources to enhance our protective measures or to investigate and remediate any information security vulnerabilities or exposures. Any breach of our system security could result in disruption of our operations, unauthorized access to confidential customer information, significant regulatory costs, litigation exposure and other possible damages, loss or liability. Such costs or losses could exceed the amount of available insurance coverage, if any, and would adversely affect our earnings. Also, any failure to prevent a security breach or to quickly and effectively deal with such a breach could negatively impact customer confidence, damaging our reputation and undermining our ability to attract and keep customers.
We may not be able to successfully implement future information technology system enhancements, which could adversely affect our business operations and profitability.
We invest significant resources in information technology system enhancements in order to provide functionality and security at an appropriate level. We may not be able to successfully implement and integrate future system enhancements, which could adversely impact the ability to provide timely and accurate financial information in compliance with legal and regulatory requirements, which could result in sanctions from regulatory authorities. Such sanctions could include fines and suspension of trading in our stock, among others. In addition, future system enhancements could have higher than expected costs and/or result in operating inefficiencies, which could increase the costs associated with the implementation as well as ongoing operations.
Failure to properly utilize system enhancements that are implemented in the future could result in impairment charges that adversely impact our financial condition and results of operations and could result in significant costs to remediate or liquidity.replace

the defective components. In addition, we may incur significant training, licensing, maintenance, consulting and amortization expenses during and after systems implementations, and any such costs may continue for an extended period of time.
We rely on other companies to provide key components of our business infrastructure.
Third party vendors provide key components of our business infrastructure such as internet connections, network access and core application processing. While we have selected these third party vendors carefully, we do not control their actions. Any problems caused by these third parties, including as a result of their not providing us their services for any reason or their performing their services poorly, could adversely affect our ability to deliver products and services to our customers or otherwise conduct our business efficiently and effectively. Replacing these third party vendors could also entail significant delay and expense.
Our internal controls, procedures and policies may fail or be circumvented.

16


Management regularly reviews and updates our internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well-designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of the controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations and financial condition.
If our risk management framework does not effectively identify or mitigate our risks, we could suffer losses.
Our risk management framework seeks to mitigate risk and appropriately balance risk and return. We have established processes and procedures intended to identify, measure, monitor and report the types of risk to which we are subject, including credit risk, operations risk, compliance risk, reputation risk, strategic risk, market risk, and liquidity risk. We seek to monitor and control our risk exposure through a framework of policies, procedures and reporting requirements. Management of our risks in some cases depends upon the use of analytical and/or forecasting models. If the models used to mitigate these risks are inadequate, we may incur losses. In addition, there may be risks that exist, or that develop in the future, that we have not appropriately anticipated, identified or mitigated. If our risk management framework does not effectively identify or mitigate our risks, we could suffer unexpected losses and could be materially adversely affected.
We may be unable to attract and retain qualified key employees, which could adversely affect our business prospects, including our competitive position and results of operations.
Our success is dependent upon our ability to attract and retain highly skilled individuals. There is significant competition for those individuals with the experience and skills required to conduct many of our business activities. We may not be able to hire or retain the key personnel that we depend upon for success. The unexpected loss of services of one or more of these or other key personnel could have a material adverse impact on our business because of their skills, knowledge of the markets in which we operate, years of industry experience and the difficulty of promptly finding qualified replacement personnel.
Natural disasters, acts of terrorism and other external events could harm our business.
Natural disasters can disrupt our operations, result in damage to our properties, reduce or destroy the value of the collateral for our loans and negatively affect the economies in which we operate, which could have a material adverse effect on our results of operations and financial condition. A significant natural disaster, such as a tornado, hurricane, earthquake, fire or flood, could have a material adverse impact on our ability to conduct business, and our insurance coverage may be insufficient to compensate for losses that may occur. Acts of terrorism, war, civil unrest, violence or human error could cause disruptions to our business or the economy as a whole. While we have established and regularly test disaster recovery procedures, the occurrence of any such event could have a material adverse effect on our business, operations and financial condition.
Our financial statements are based in part on assumptions and estimates, which, if wrong, could cause unexpected losses in the future.
Pursuant to accounting principles generally accepted in the U.S., we are required to use certain assumptions and estimates in preparing our financial statements, including in determining loan loss and litigation reserves, goodwill impairment and the fair value of certain assets and liabilities, among other items. If assumptions or estimates underlying our financial statements are incorrect, we may experience material losses. See the "Critical Accounting Policies" section in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."
Changes in generally accepted accounting principlesstandards can be difficult to predict and can materially impact how we record and report our financial condition and results of operations.

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. From time to time, the Financial Accounting Standards Board changes the financial accounting and reporting principles that govern the preparation of our financial statements. These changes can be hard to anticipate and implement, and can materially impact how we record and report our financial condition and results of operations. In some cases, we could be required to apply a new or revised standard retroactively, resulting in our restating prior period financial statements. Additionally, significant changes to accounting standards may require costly technology changes, additional training and personnel, and other expense that will negatively impact our results of operations.
A new accounting standard may require us to increase our allowance for loan losses and may have a material adverse effect on our financial condition and results of operations.
The Financial Accounting Standards Board has issued Accounting Standards Update 2016-13, which will be effective for the Company for the first quarter of the fiscal year ending December 31, 2020. This standard, often referred to as “CECL” (reflecting a current expected credit loss model), will require companies to recognize an allowance for credit losses based on estimates of losses expected to be realized over the contractual lives of the loans. Under current U.S. GAAP, companies generally recognize credit losses only when it is probable that a loss has been incurred as of the balance sheet date. This new standard will require us to collect and review increased types and amounts of data for us to determine the appropriate level of the allowance for loan losses, and may require us to increase our allowance for loan losses. Any increase in our allowance for loan losses or expenses incurred to determine the appropriate level of the allowance for loan losses may have a material adverse effect on our financial condition and results of operations. We are currently evaluating the impact of adopting this standard on our consolidated financial statements.
Changes in tax laws and regulations and differences in interpretation of tax laws and regulations may adversely impact our financial statements.
From time to time, local, state or federal tax authorities change tax laws and regulations, which may result in a decrease or increase to our net deferred tax assets. Local, state or federal tax authorities may interpret tax laws and regulations differently than we do and challenge tax positions that we have taken on tax returns. This may result in differences in the treatment of revenues, deductions, credits and/or differences in the timing of these items. The differences in treatment may result in payment of additional taxes, interest or penalties that could have a material adverse effect on our results.
Future capital offerings may adversely affect the market price of our common stock.
In the future, we may attempt to increase our capital resources or, if our or our banking subsidiaries' capital ratios fall below required minimums, we could be forced to raise additional capital by making additional offerings of debt, common or preferred stock, trust preferred securities, and senior or subordinated notes. Upon liquidation, holders of our debt securities and shares of preferred stock and lenders with respect to other borrowings will receive distributions of our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing stockholders or reduce the market price of our common stock, or both. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Moreover, we cannot assure you that such capital will be available to us on acceptable terms or at all. Our inability to raise sufficient additional capital on acceptable terms when needed could adversely affect our businesses, financial condition and results of operations.
The market price and trading volume of our common stock may be volatile.
The market price of our common stock may be volatile. In addition, the trading volume in our common stock may fluctuate and cause significant price variations to occur. We cannot assure you that the market price of our common stock will not fluctuate or decline significantly in the future. Some of the factors that could negatively affect our share price or result in fluctuations in the price or trading volume of our common stock include:

17


quarterly variations in our operating results or the quality of our assets;
operating results that vary from the expectations of Management,management, securities analysts and investors;
changes in expectations as to our future financial performance;
announcements of innovations, new products, strategic developments, significant contracts, acquisitions and other
material events by us or our competitors;
the operating and securities price performance of other companies that investors believe are comparable to us;
our past and future dividend practices;

future sales of our equity or equity-related securities; and
changes in global financial markets and global economies and general market conditions, such as interest rates, stock,
commodity or real estate valuations or volatility.
Anti-takeover provisions could negatively impact our stockholders.
Provisions of Delaware law and provisions of our certificate of incorporation and by-laws could make it more difficult for a third party to acquire control of us or have the effect of discouraging a third party from attempting to acquire control of us, even if an acquisitiona merge might be in the best interest of our stockholders.
To the extent that we acquire other companies, our business may be negatively impacted by certain risks inherent with such acquisitions.
In 2018, we completed the acquisition of First Commons Bank. We have acquired and will continue to consider the acquisition of other financial services companies. To the extent that we acquire other companies in the future, our business may be negatively impacted by certain risks inherent with such acquisitions. Some of these risks include the following:
The risk that the acquired business will not perform in accordance with management's expectations;
The risk that difficulties will arise in connection with the integration of the operations of the acquired business with the operations of our businesses;
The risk that management will divert its attention from other aspects of our business;
The risk that we may lose key employees of the combined business; and
The risks associated with entering into geographic and product markets in which we have limited or no direct prior experience.
We may be required to write down goodwill and other acquisition-related identifiable intangible assets.
When we acquire a business, such as First Commons Bank, a portion of the purchase price of the acquisition may be allocated to goodwill and other identifiable intangible assets. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets acquired determines the amount of the purchase price that is allocated to goodwill acquired. As of December 31, 2018, goodwill and other identifiable intangible assets were $166.5 million. Under current accounting guidance, if we determine that goodwill or intangible assets are impaired, we would be required to write down the value of these assets. We conduct an annual review to determine whether goodwill and other identifiable intangible assets are impaired. We conduct a quarterly review for indicators of impairment of goodwill and other identifiable intangible assets. Our management recently completed these reviews and concluded that no impairment charge was necessary for the year ended December 31, 2018. We cannot provide assurance whether we will be required to take an impairment charge in the future. Any impairment charge would have a negative effect on stockholders' equity and financial results and may cause a decline in our stock price.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations
Introduction
Brookline Bancorp, Inc. (the "Company"),The Company, a Delaware corporation, operates as a multi-bank holding company for Brookline Bank and its subsidiaries; Bank Rhode Island ("BankRI")BankRI and its subsidiaries; First Ipswich Bank ("First Ipswich") and its subsidiaries; and Brookline Securities Corp.
As a commercially-focused financial institution with 4951 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”),the Banks, offers a wide range of commercial, business and retail banking services, including a full complement of cash management products, foreign exchange services, on-line and mobile banking services, consumer and residential loans and investment advisory services, designed to meet the financial needs of small- to mid-sized businesses and individuals throughout central New England. Specialty lending activities include equipment financing primarily in the New York and New Jersey metropolitan area.

The Company focuses its business efforts on profitably growing its commercial lending businesses, both organically and
through acquisitions. The Company’s customer focus, multi-bank structure, and risk management are integral to its organic
growth strategy and serve to differentiate the Company from its competitors. As full-service financial institutions, the Banks
and their subsidiaries focus their efforts on the continued acquisition of well-qualified customers, thedeveloping and deepening of long-term banking
relationships with qualified customers through a full complement of products and excellent customer service, and strong risk management.
The Company manages the Banks under uniform strategic objectives, with one set of uniform policies consistently applied by one executive management team. Within this environment, the Company believes that the ability to make customer decisions locally enhances Management'smanagement's motivation, service levels and, as a consequence, the Company's financial results. As such, while most back-office functions are consolidated at the holding company level, branding and decision-making, including credit decisions and pricing, remain largely local in order to better meet the needs of bank customers and further motivate the Banks’ commercial, business and retail bankers. These credit decisions, at the local level, are executed through corporate policies overseen by the Company's credit department.
The competition for loans and leases and deposits remains intense. While there are signs that the economy has improved in 2015,2018, the Company expects the operating environment in 20162019 to remain challenging. The volume of loan and lease originations and loan and lease losses will depend, to a large extent, on how the economy performs. Loan and lease growth and deposit growth are also greatly influenced by the rate-setting actions of the Board of Governors of the Federal Reserve System (“FRB”). TheFRB. A sustained, low interest rate environment has had andwith a flat interest rate curve may continue to have a negativenegatively impact on the Company's yields and net interest margin. Conversely,While the Company is slightly asset sensitive and should benefit from rising rates, in the futurethese rate increases could cause changesprecipitate a change in the mix and volume of the Company's deposits and make it more difficult for certain borrowers to be eligible for new loans or leases or to service their existing debt.loans. The future operating results of the Company will depend on its ability to maintain or increase the current net interest margin, while minimizing exposure to credit risk, along with increasing sources of non-interest income, while controlling the growth of non-interest or operating expenses.
The Company and the Banks are supervised, examined and regulated by the FRB. As a Massachusetts-chartered savings bank and trust company, respectively, Brookline Bank and First Ipswich are also subject to regulation under the laws of the Commonwealth of Massachusetts and the jurisdiction of the Massachusetts Division of Banks. As a Rhode Island-chartered financial institution, BankRI is also subject to regulation under the laws of the State of Rhode Island and the jurisdiction of the Banking Division of the Rhode Island Department of Business Regulation. The Federal Deposit Insurance Corporation ("FDIC")FDIC continues to insure each of the Banks’ deposits up to $250,000 per depositor. Additionally, asAs a Massachusetts-chartered savings bank, Brookline Bank is also insured by the Depositors Insurance Fund (“DIF”),DIF, a private industry-sponsored company. The DIF insures savings bank deposits in excess of the FDIC insurance limits. As such, Brookline Bank offers 100% insurance on all deposits as a result of a combination of insurance from the FDIC and the DIF.
The Company’s common stock is traded on the Nasdaq Global Select MarketSMMarketSM under the symbol “BRKL.”

Asset Quality
Nonperforming assets as of December 31, 2018 totaled $28.1 million, or 0.38% of total assets, compared to $31.7 million, or 0.47% of total assets, as of December 31, 2017. Net charge-offs for the year ended December 31, 2018 were $4.7 million, or 0.08% of average loans and leases, compared to $13.9 million, or 0.25% of average loans and leases, for the year ended December 31, 2017.The decrease in nonperforming loans and leases and nonperforming assets was primarily driven by the charge offs and pay downs on certain taxi medallion loans.
The ratio of the allowance for loan and lease losses to total loans and leases was 1.14%0.93% as of December 31, 2015,2018, compared to 1.11%1.02% as of December 31, 2014. The2017. Excluding the loans acquired from BankRI, First Ipswich and First Commons Bank, the allowance for loan and lease losses related to originated loans and leases as a percentage of the total originated loan and lease portfolio was 1.20%0.96% as of December 31, 2015 and2018, compared to 1.05% as of December 31, 2014.2017. The Company continued to employ its historical ALLLunderwriting methodology and inthroughout the third quarter 2014, incorporated a loss emergencetwelve month period ("LEP") to its ALLL methodology. The LEP incorporates a study of the time period from the first indication of elevated risk of repayment (or other early event indicating a problem) to eventual charge-off to support the LEP considered in the ALLL calculation. During the third quarter of 2015, the Company enhanced and refined its general allowance methodology to provide further quantification of probable losses in the portfolio. Under this enhanced methodology, Management combined the historical loss histories of the Banks to generate a single set of ratios.
Nonperforming assets as of December 31, 2015 totaled $20.7 million, or 0.34% of total assets, compared to $15.2 million, or 0.26% of total assets, as of December 31, 2014.

Net Income
For the year ended December 31, 2015,2018, the Company reported net income of $49.8$83.1 million, or $0.71$1.04 per basic and diluted share, an increase of $6.5$32.5 million, or 15.0%64.4%, from $43.3$50.5 million, or $0.62$0.68 per basic and diluted share for the year ended December 31, 2014.2017. The increase in net income is primarily the result of an increase in net interest income of $5.3$24.5 million, a decrease in the provision for income taxes of $17.4 million, a decrease in the provision for credit losses of $1.0$14.0 million, a decrease in non-interest expense of $3.8 millionpartially offset by an increase in provision fornon-interest expense of $16.1 million and a decrease in non-interest income taxes of $3.1$6.9 million.
The return on average assets was 0.85%1.15% for the year ended December 31, 2015,2018, compared to 0.78%0.76% for the year ended December 31, 2014.2017.

The net interest margin was 3.54% for the year ended December 31, 2015 down from 3.61% for the year ended December 31, 2014.2018 up from 3.57% for the year ended December 31, 2017. The compressionincrease in the net interest margin is a result of a decreasean increase in the yield on interest-earning assets by 738 basis points to 4.12%4.58% in 20152018 from 4.19%4.20% in 2014, and2017, partially offset by an increase of 337 basis points in the Company's overall cost of funds to 0.63%1.06% in 20152018 from 0.60%0.69% in 2014. The decrease in the yield on interest-earning assets was largely due to continued rate pressures on the loan portfolio. The Company continued to experience competitive pressure in all categories in 2015 including the continuation of a low interest-rate environment and the Company's diminishing ability to reduce its costs, all of which contributed to the decline in the net interest margin.  Despite these challenges, the Company’s net interest income increased $5.3 million due to growth in interest earning assets and a shift in the mix of those assets from lower yielding indirect auto loans to higher yielding commercial loans.2017.
Results for 20152018 included a $7.5$5.0 million provision for credit losses, as discussed in the "Allowance for Credit Losses—Allowance for Loan and Lease Losses" section below.

Several factors contributed to the year over year increase,decrease, including a decrease of $11.2 million in gain on sales of securities recorded in the first quarter of 2017, partially offset by an increase of $2.5$3.3 million in loan level derivative income and an increase of $0.6 million in gain on sales of loans and leases held-for-sale, offset by a decrease of $1.5 million in gain on sale of premises and equipment, and a decrease of $1.71.1 million in other non-interest income.
Non-interest expense decreased $3.8increased $16.1 million to $125.4$155.2 million for the year ended December 31, 20152018 from $129.2$139.1 million for the year ended December 31, 2014.2017. The decreaseincrease was largely attributable to a decreasean increase of $2.2$9.1 million in compensation and employee benefits, an increase of $3.4 million in merger and acquisition expense, an increase of $1.7 million in other non-interest expense and an increase of $1.4 million in equipment and data processing, a decrease of $1.2 million in professional services, and a decrease of $0.5 million in compensation and employee benefit expense.processing.

Critical Accounting Policies
The accounting policies described below are considered critical to understanding the Company's financial condition and operating results. Such accounting policies are considered to be especially important because they involve a higher degree of complexity and require Managementmanagement to make difficult and subjective judgments which often require assumptions or estimates about matters that are inherently uncertain. The use of different judgments, assumptions and estimates could result in material differences in the Company's operating results or financial condition.
Valuation of Investment Securities
Investment securities classified as available-for-sale are carried at estimated fair value, with any unrealized gains and losses, net of taxes, reported as accumulated other comprehensive income or loss in stockholders' equity. Debt securities that the Company has the positive intent and ability to hold to maturity are classified as "held-to-maturity" and are carried at amortized cost. Investment securities classified as held-for-trading securities are recorded on a marked-to-market basis with realized gains and losses recognized through the income statement.
The market values of the Company's investment securities, particularly its fixed-rate securities, are affected by changes in market interest rates as determined by the term structure of risk-free rates and the credit spreads associated with different investment categories. In general, as interest rates rise, the fair value of fixed-rate securities will decrease; as interest rates fall, the fair value of fixed-rate securities will increase. On a quarterly basis, the Company reviews and evaluates fair value based on market data obtained from independent sources or, in the absence of active market data, from model-derived valuations based on market assumptions. If the Company deems any decline to be other-than-temporary, the amount of impairment loss recorded in earnings for a debt security is the entire difference between the security's cost and its fair value if the Company intends to sell the debt security prior to recovery or it is more likely than not that the Company will have to sell the debt security prior to recovery. If, however, the Company does not intend to sell the debt security or it concludes that it is more likely than not that the Company will not have to sell the debt security prior to recovery, the credit loss component of an other-than-temporary impairment of a debt security is recognized as a charge to earnings and the remaining portion of the impairment loss is recognized as a reduction in comprehensive income. The credit loss component of an other-than-temporary loss is determined based on the Company's best estimate of cash flows expected to be collected. There were no impairment losses charged to earnings in 2015, 20142018, 2017 and 2013.2016.
See Note 21, "Fair Value of Financial Instruments" to the consolidated financial statements for additional information on how Managementmanagement determines the fair value of its financial instruments.
Valuation of Acquired Loans
Loans that the Company acquired are initially recorded at fair value with no carryover of the related allowance for loan and lease losses. Determining the fair value of the acquired loans involves estimating the amount and timing of principal and interest cash flows initially expected to be collected on the loans and discounting those cash flows at an appropriate market rate of interest. The Company continues to evaluate the reasonableness of expectations for the timing and the amount of cash to be collected. Subsequent decreases in expected cash flows may result in changes in the amortization or accretion of fair market value adjustments, and in some cases may result in a loan being considered impaired.
Allowance for Loan and Lease Losses
The allowance for loan and lease losses represents Management'smanagement's estimate of probable losses inherent in the loan and lease portfolio. Additions to the allowance for loan and lease losses are made by charges to the provision for credit losses. Losses on loans and leases are deducted from the allowance when all or a portion of a loan or lease is considered uncollectable. The determination of the loans on which full collectability is not reasonably assured, the estimates of the fair value of the underlying collateral, and the assessment of economic and other conditions are subject to assumptions and judgments by Management.management. Valuation allowances could differ materially as a result of changes in, or different interpretations of, these assumptions and judgments.

25


Management evaluates the adequacy of the allowance on a quarterly basis and reviews its conclusion as to the amount to be established with the Audit Committee and the Board of Directors.
See Note 7, "Allowance for Loan and Lease Losses," to the consolidated financial statements for additional information on how Managementmanagement determines the balance of the allowance for loan and lease losses for each portfolio and class of loans.
Impairment of Goodwill
Goodwill is presumed to have an indefinite useful life and is tested at least annually for impairment. Impairment exists when the carrying amount of goodwill exceeds its implied fair value. If fair value exceeds the carrying amount at the time of

testing, goodwill is not considered impaired. Quoted market prices in active markets are the best evidence of fair value and are considered to be used as the basis for measurement, when available. Other acceptable valuation methods include present-value measurements based on multiples of earnings or revenues, or similar performance measures. Differences in valuation techniques could result in materially different evaluations of impairment. In September 2011, the FASB issued Accounting Standards Update ("ASU") 2011-08 which provides guidance for companies when testing goodwill for impairment. The objective of the ASU is to simplify how entities test goodwill for impairment. Pursuant to the ASU, entities may now assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The more-likely-than-not threshold is defined as having a likelihood of more than 50%.
To determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an entity should consider the extent to which each of the adverse events or circumstances identified could affect the comparison of a reporting unit's fair value with its carrying amount.
Pursuant to the ASU, an entity should place more weight on the events and circumstances that have the greatest impact on a reporting unit's fair value or the carrying amount of its net assets; and may affect its determination of whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount.
Qualitative factors that have been assessed to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount including goodwill: general economic conditions, regulatory environment, share price, real estate values, lending concentrations, interest-rate environment, asset quality, capital, financial performance, integration of acquired companies and conversion to a new data processing system.
The Company has evaluated the qualitative factors discussed above and assessed the effect identified adverse events or circumstances could have, and based on this analysis has concluded there was no indication of goodwill impairment as of December 31, 2015.2018. Further analysis of the Company’s goodwill can be found in Note 9 “Goodwill and Other Intangible Assets” within notes to the consolidated financial statements.
Identified Intangible Assets
Identified intangible assets are assets resulting from acquisitions that are being amortized over their estimated useful lives. The recoverability of identified intangible assets is evaluated for impairment at least annually. If impairment is deemed to have occurred, the amount of impairment is charged to expense when identified.
Income Taxes
Certain areas of accounting for income taxes require Management'smanagement's judgment, including determining the expected realization of deferred tax assets and the adequacy of liabilities for uncertain tax positions. Judgments are made regarding various tax positions, which are often subjective and involve assumptions about items that are inherently uncertain. If actual factors and conditions differ materially from estimates made by Management,management, the actual realization of the net deferred tax assets or liabilities for uncertain tax positions could vary materially from the amounts previously recorded.
Deferred tax assets arise from items that may be claimed as a tax deduction or credit in future income tax returns, for which a financial statement tax benefit has been recognized. The Company’s realization of the deferred tax asset depends upon future levels of its taxable income and the existence of prior years' taxable income for which claims for refunds can be carried back. Where necessary, valuation allowances are recorded against those deferred tax assets which a Company has determined will not be realized. Deferred tax liabilities represent items that will require a future tax payment. Deferred tax liabilities generally represent tax expense recognized in the Company's financial statements for which payment has been deferred, or a deduction claimed on the Company's tax return but not yet recognized as an expense in the Company's financial statements. Deferred tax liabilities are also recognized for certain non-cash items such as goodwill.

See Note 1, “Basis of Presentation” withinin the notes to the consolidated financial statements for information regarding recent accounting developments.

Non-GAAP Financial Measures and Reconciliation to GAAP
In addition to evaluating the Company'sCompany’s results of operations in accordance with GAAP, Managementmanagement periodically supplements this evaluation with an analysis of certain non-GAAP financial measures, such as operating earnings metrics, the return on average tangible assets, orreturn on average tangible equity, the tangible equity ratio, tangible book value per share, dividend payout ratio, and the ratio of the allowance for loan and lease losses related to originated loans and leases as a percentage of originated loans and leases. Management believes that these non-GAAP financial measures provide information useful information to investors forin understanding the Company'sCompany’s underlying operating performance and trends. These non-GAAP financial measures may also aid investors in facilitatingtrends, and facilitates comparisons with the performance assessment of the Company's 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'sCompany’s capital position.
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.
Operating Earnings
Operating earnings exclude compensation-relatedthe after-tax impact of securities gains and acquisition-related items from net income.merger and acquisition expense as well as the impact of the Tax Reform Act. By excluding such items, the Company's results can be measured and assessed on a more consistent basis from period to period. Items excluded from operating earnings are also excluded when calculating the operating return and operating efficiency ratios.

The Company's loan portfolio consists primarily of first mortgage loans secured by commercial, multi-family and residential real estate properties located in the Company's primary lending area, loans to business entities, including commercial lines of credit, loans to condominium associations and loans and leases used to finance equipment used by small businesses. The Company also provides financing for construction and development projects, home equity and other consumer loans.
The Company employs seasoned commercial lenders and retail bankers who rely on community and business contacts as well as referrals from customers, attorneys and other professionals to generate loans and deposits. Existing borrowers are also an important source of business since many of them have more than one loan outstanding with the Company. The Company's ability to originate loans depends on the strength of the economy, trends in interest rates, and levels of customer demand and market competition.

31


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

As of December 31, 2015,2018, there were twotwelve borrowers with aggregated loans outstanding ofcommitments over $35.0 million or greater.million. The total of those loanscommitments was $95.1$520.8 million or 1.90%6.9% of total loans outstandingcommitments as of December 31, 2015.2018.
The Company has written underwriting policies to control the inherent risks in loan origination. The policies address approval limits, loan-to-value ratios, appraisal requirements, debt service coverage ratios, loan concentration limits and other matters relevant to loan underwriting.
Commercial Real Estate Loans
The commercial real estate portfolio is comprised of commercial real estate loans, multi-family mortgage loans, and construction loans and is the largest component of the Company's overall loan portfolio, representing 53.3%53.1% of total loans and leases outstanding as of December 31, 2015.2018.
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. For commercial customers who are interested in loans with fixed rate terms longer than five years, the Company offers interest rate swapsloan level derivatives to accommodate customer need.
The Company's urban and suburban market area is characterized by a large number of apartment buildings, condominiumsoffice buildings, and office buildings.retail stores, among others. As a result, commercial real estate and multi-family mortgage lending has been a significant part of the Company's activities for many years. These types of loans typically generate higher yields, but also involve greater credit risk. Many of the Company's borrowers have more than one multi-family or commercial real estate loan outstanding with the Company. The Company monitors the commercial real estate portfolio for tenant exposures; both by company and industry.
The commercial real estate portfolio was composed primarily of loans secured by apartment buildings ($679.4773.5 million), office buildings ($628.5678.9 million), retail stores ($511.4593.5 million), industrial properties ($299.2248.0 million), mixed-use properties ($259.4 million), lodging services ($120.3 million) and mixed-use propertiesto food services ($201.558.1 million) as of December 31, 2015.2018. At that date, over 97%97.2% of the commercial real estate loans outstanding were secured by properties located in New England.
Construction and development financing is generally considered to involve a higher degree of risk than long-term financing on improved, occupied real estate and thus has lower concentration limits than do other commercial credit classes. Risk of loss on a construction loan is largely dependent upon the accuracy of the initial estimate of construction costs, the estimated time to sell or rent the completed property at an adequate price or rate of occupancy, and market conditions. If the estimates and projections prove to be inaccurate, the Company may be confronted with a project which, upon completion, has a value that is insufficient to assure full loan repayment.
Criteria applied in underwriting construction loans for which the primary source of repayment is the sale of the property areis 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

32


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

Commercial Loans
The commercial loan and lease portfolio is comprised of commercial loans, equipment financing loans and leases and condominium association loans and represented 27.6%28.1% of total loans outstanding as of December 31, 2015.2018.
The commercial loan and lease portfolio is composed primarily of loans to small businesses ($556.5 million), transportation services ($381.6 million), recreation services ($114.5 million), food services ($121.1 million), manufacturing ($76.0 million), rental and leasing services ($46.8 million), and retail ($72.7 million) as of December 31, 2018.
The Company provides commercial banking services to companies in its market area. Over 50%Approximately 45.9% of the commercial loans outstanding as of December 31, 20152018 were made to borrowers located in New England. Over 17% of the outstanding balances were made to borrowers in New York and New Jersey by the Company's equipment financing divisions. The remaining 50%54.1% of the commercial loans outstanding were made to borrowers in other areas in the United States of America.America, primarily by the Company's equipment financing divisions. Product offerings include lines of credit, term loans, letters of credit, deposit services and cash management. These types of credit facilities have as their primary source of repayment cash flows from the operations of a business. Interest rates offered are available on a floating basis tied to the prime rate or a similar index or on a fixed-rate basis referenced on the Federal Home Loan Bank of Boston ("FHLBB") index.
Credit extensions are made to established businesses on the basis of loan purpose and assessment of capacity to repay as determined by an analysis of their financial statements, the nature of collateral to secure the credit extension and, in most instances, the personal guarantee of the owner of the business as well as industry and general economic conditions. The Company also participates in U.S. Government programs such as the Small Business Administration (the "SBA") in both the 7A program and as an SBA preferred lender.
The Company’s equipment financing divisions focus on market niches in which its lenders have deep experience and industry contacts, and on making loans to customers with business experience. An important part of the Company’s equipment financing loan origination volume comes from equipment manufacturers and existing customers as they expand their operations. The equipment financing portfolio is composed primarily of loans to finance laundry, tow trucks, fitness, dry cleaning and convenience store equipment. TheApproximately 15.3% of the commercial loans outstanding were made to borrowers are located primarily in the greater New York and New Jersey metropolitan area, although the customer base extends to locations throughout the United States.area. Typically, the loans are priced at a fixed rate of interest and require monthly payments over their three- to seven-year life. The yields earned on equipment financing loans are higher than those earned on the commercial loans made by the Banks because they involve a higher degree of credit risk. Equipment financing customers are typically small-business owners who operate with limited financial resources and who face greater risks when the economy weakens or unforeseen adverse events arise. Because of these characteristics, personal guarantees of borrowers are usually obtained along with liens on available assets. The size of loan is determined by an analysis of cash flow and other characteristics pertaining to the business and the equipment to be financed, based on detailed revenue and profitability data of similar operations.
Loans to condominium associations are for the purpose of funding capital improvements, are made for five- to ten-year terms and are secured by a general assignment of condominium association revenues. Among the factors considered in the underwriting of such loans are the level of owner occupancy, the financial condition and history of the condominium association, the attractiveness of the property in relation to the market in which it is located and the reasonableness of estimates of the cost of capital improvements to be made. Depending on loan size, funds are advanced as capital improvements are made and, in more complex situations, after completion of engineering inspections.
Consumer Loans
The consumer loan portfolio is comprised of residential mortgage loans, home equity loans and lines of credit, and other consumer loans and indirect automobile loans and represented 19.1%18.8% of total loans outstanding as of December 31, 2015.2018. The Company focuses its mortgage loansand home equity lending on existing and new customers within its branch networks in its urban and suburban marketplaces in the greater Boston and Providence metropolitan areas. Loans outstanding in the indirect automobile portfolio totaled $13.7 million as of December 31, 2015, down from $317.0 million as of December 31, 2014. In December 2014, the Company ceased the origination of indirect automobile loans and in March 2015 sold $255.2 million of the indirect automobile loan portfolio. As of December 31, 2015, the Company continues to service the remaining portfolio.The
The Company originates adjustable- and fixed-rate residential mortgage loans secured by one- to four-family residences. Each residential mortgage loan granted is subject to a satisfactorily completed application, employment verification, credit history and a demonstrated ability to repay the debt. Generally, loans are not made when the loan-to-value ratio exceeds 80% unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Appraisals are performed by outside independent fee appraisers.
In general, the Company maintains three-, five- and seven-year adjustable-rate mortgage loans and ten-year fixed-rate fully amortizing mortgage loans in its portfolio. Fixed-rate mortgage loans with maturities beyond ten years, such as 15- and 30-year fixed-rate mortgages, are generally sold into the secondary market on a servicing-released basis. The Banks act as

33


correspondent banks in these secondary-market transactions. Loan sales in the secondary market provide funds for additional lending and other banking activities.

Underwriting guidelines for home equity loans and lines of credit are similar to those for residential mortgage loans. Home equity loans and lines of credit are limited to no more than 80% of the appraised value of the property securing the loan including the amount of any existing first mortgage liens.
Other consumer loans have historically been a modest part of the Company's loan originations. As of December 31, 2015,2018, other consumer loans equaled $12.2$23.4 million, or 0.2%0.4% of total loans outstanding. Consumer 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 Managementmanagement rates certain loans and leases as "other assets especially mentioned ("OAEM")", "substandard" or "doubtful" based on criteria established under banking regulations. Refer to Note 7, "Allowance for Loan and Lease Losses," to the consolidated financial statements for more information on the Company's risk rating system. These loans and leases are collectively referred to as "criticized" assets. Loans and leases rated OAEM have potential weaknesses that deserve Management'smanagement's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects of the loan or lease at some future date. Loans and leases rated as substandard are inadequately protected by the payment capacity of the obligor or of the collateral pledged, if any. Substandard loans and leases have a well-defined weakness or weaknesses that jeopardize the liquidation of debt and are characterized by the distinct possibility that the Company will sustain some loss if existing deficiencies are not corrected. Loans and leases rated as doubtful have well-defined weaknesses that jeopardize the orderly liquidation of debt and partial loss of principal is likely. As of December 31, 2015,2018, the Company had $49.0$58.6 million of total assets, including acquired assets, that were designated as criticized. This compares to $71.4$68.2 million of assets designated as criticized as of December 31, 2014.2017. The decrease in criticized assets was primarily due to the charge-offs in taxi medallion loans and the pay offs in criticized loans and leases during the year ended December 31, 2018.
Nonperforming Assets
"Nonperforming assets" consist of nonperformingnonaccrual loans and leases, other real estate owned ("OREO") and other repossessed assets. Under certain circumstances, the Company may restructure the terms of a loan or lease as a concession to a borrower, except for acquired loans and leases which are individually evaluated against expected performance on the date of acquisition. These restructured loans and leases are generally considered "nonperforming loans and leases" until a history of collection of at least six months on the restructured terms of the loan or lease has been established. OREO consists of real estate acquired

through foreclosure proceedings and real estate acquired through acceptance of a deed in lieu of foreclosure. Other repossessed assets consist of assets that have been acquired through foreclosure that are not real estate and are included in other assets on the Company's consolidated balance sheets.
Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in Management's judgment, reasonable doubt exists as to the full timely collection of interest. Exceptions may be made if the loan has matured and is in the process of renewal or is well-secured and in the process of collection. When a loan is placed on nonaccrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current interest income. Interest payments on nonaccrual loans are generally applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are generally returned to accrual status when principal and interest payments are current, full collectability of principal and interest is reasonably assured and a consistent record of at least six months of performance has been achieved.
In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a troubled debt restructured loan. In determining whether a debtor is experiencing financial difficulties, the Company considers, among other factors, if the debtor is in payment default or is likely to be in payment default in the foreseeable future without the modification, the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor's entity-specific projected cash flows will not be sufficient to service its debt, or the debtor cannot obtain funds from sources other than the existing creditors at market terms for debt with similar risk characteristics.
Nonperforming assets are composed of nonaccrual loans and leases, OREO and other repossessed assets. As of December 31, 2015,2018, the Company had nonperforming assets of $20.7$28.1 million, representing 0.34%0.38% of total assets, compared to nonperforming assets of $15.2$31.7 million, or 0.26%0.47% of total assets, as of December 31, 2014.2017. The decrease in nonperforming assets was primarily due to the partial charge-off of loans secured by taxi medallions during the year ending December 31, 2018.
The Company evaluates the underlying collateral of each nonperformingnonaccrual loan and lease and continues to pursue the collection of interest and principal. Management believes that the current level of nonperforming assets remains manageable relative to the size of the Company's loan and lease portfolio. If economic conditions were to worsen or if the marketplace were to experience prolonged economic stress, Managementmanagement believes it is likely that the level of nonperforming assets would increase, as would the level of charged-off loans.        
Past Due and Accruing
Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in Management'smanagement'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. In addition, loans categorized as ASC 310-30 accrue regardless of past due status. When a loan is placed on nonaccrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current interest income. Interest payments on nonaccrual loans are generally applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are generally returned to accrual status

36


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.
As of December 31, 2015,2018, the Company had loans and leases greater than 90 days past due and accruing of $8.7$13.5 million, or 0.17%0.21% of total loans and leases, compared to $6.0$3.0 million, or 0.12%0.05% of total loans and leases, as of December 31, 2014,2017, representing an increase of $2.7$10.5 million. The increase was related primarily due to one acquired commercial real estate loan which was overgreater than 90 days past due and accruing with an outstanding balance of $2.8 million as of December 31, 2015.accruing. These loans are therefore not included in the non-performing assets category.

Allowances for Credit Losses
Allowance for Loan and Lease Losses
The allowance for loan and lease losses consists of general and specific allowances and reflects Management'smanagement's estimate of probable loan and lease losses inherent in the loan portfolio at the balance sheet date. Management uses a consistent and systematic process and methodology to evaluate the adequacy of the allowance for loan and lease losses on a quarterly basis. The allowance is calculated by loan type: commercial real estate loans, commercial loans and leases, and consumer loans, each category of which is further segregated. A formula-based credit evaluation approach is applied to each group that is evaluated collectively, primarily by loss factors, which includes estimates of incurred losses over an estimated LEP,loss emergence period ("LEP"), assigned to each risk rating by type, coupled with an analysis of certain loans individually evaluated for impairment. Management continuously evaluates and challenges inputs and assumptions in the allowance for loan and lease loss.
The process to determine the allowance for loan and lease losses requires Managementmanagement to exercise considerable judgment regarding the risk characteristics of the loan portfolios and the effect of relevant internal and external factors. While Managementmanagement 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 7, "Allowance for Loan and Lease Losses," to the consolidated financial statements for descriptions of how Managementmanagement determines the balance of the allowance for loan and lease losses for each portfolio and class of loans.
During the third quarter of 2015, the Company enhanced and refined its general allowance methodology to provide further quantification of probable losses in the portfolio. Under the enhanced methodology, Managementmanagement combined the historical loss histories of the Banks to generate a single set of ratios. Management believes it is appropriate to aggregate the ratios as the Banks share common environmental factors, operate in similar geographic markets, and utilize common underwriting standards in accordance with the Company's Credit Policy. In prior periods, a historical loss history applicable to each Bank was used.

38



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

The Company’sAs of December 31, 2018, the Company had a portfolio of approximately $13.7 million in loans secured by taxi medallions issued by the cities of Boston and Cambridge. As of December 31, 2017, this portfolio was approximately $19.7 million. Application-based mobile ride services, such as Uber and Lyft, have generated increased competition in the transportation sector, resulting in a reduction in taxi utilization and, as a result, a reduction in the collateral value and credit quality of taxi medallion loans. This has increased the likelihood that loans secured by taxi medallions may default, or that the borrowers may be unable to repay these loans according to terms, resulting in an increase in past due loans, troubled debt restructurings, and charge-offs. Therefore, beginning with the three months ended September 30, 2015, the Company’s allowance calculation included a further segmentation of the commercial loans and leases to reflect the increased risk in the Company’s taxi medallion portfolio. As of December 31, 2015, this portfolio is approximately $35.8 million. Based on industry conditions, Management established a specific loss factor for this portfolio that best represents the changing risks associated with it.

Based on the refinements to the Company’s allowance methodology discussed above, Managementmanagement determined that the potential risks anticipated by the unallocated allowance are now incorporated into the qualitative and quantitative components, making the unallocated allowance unnecessary. In prior years, the unallocated allowance was used to recognize the estimated risk associated with the allocated general and specific allowances. It incorporated Management’smanagement’s evaluation of existing conditions that were not included in the allocated allowance determinations and provided for losses that arise outside of the ordinary course of business.
The following tables present the changes in the allowance for loan and lease losses by portfolio category for the years ended December 31, 2018, 2017, 2016, 2015, 2014, 2013, 2012, and 2011,2014, respectively.

The allowance for loan and lease losses was $56.7$58.7 million as of December 31, 2015,2018, or 1.14%0.93% of total loans and leases outstanding. This compared to an allowance for loan and lease losses of $53.7$58.6 million, or 1.11%1.02% of total loans and leases outstanding, as of December 31, 2014.2017. The increase in the allowance for loan and lease losses and in the allowance for loan and lease losses as a percentage of total loans and leases from December 31, 20142017 to December 31, 2015 is2018 was primarily due to originated loan growth of $172.9$418.5 million, during the year, a specific reserve recorded for a commercial relationship which was downgraded in the first

40


quarter, and an increase in reserves for taxi medallion loans, which were partially offset by the release of reserves relateddecrease in reserve due to changes in historical loss factors applied to the sale of the indirect automobile portfolio during the first quarter and a reduction of the reserves for the acquired loan portfolios.
Management believes that the allowance for loan and lease losses as of December 31, 20152018 is appropriate based on the facts and circumstances discussed further below.

Commercial Real Estate Loans
The allowance for commercial real estate loan losses was $30.2$28.2 million, or 1.13%0.84% of total commercial real estate loans outstanding, as of December 31, 2015.2018.

Specific reserves on commercial real estate loans were $2.3 million and $0.1 millionfive thousand as of December 31, 2015 and2018, compared to none at December 31, 2014, respectively.2017. The $0.6$1.1 million increase in the allowance for commercial real estate loan losses during 20152018 was primarily driven by the increase in reserves on one acquired commercial real estate loan with deteriorated credit, as well as the originated loan growth of $287.2$214.4 million, or 13.4%7.3% from December 31, 2014 and the deterioration of one relationship in the commercial real estate loan portfolio during the first quarter of 2015, partially offset by the improved credit quality of other commercial real estate loans.2017.
The ratio of total criticized and classified commercial real estate loans to total commercial real estate loans decreased to 1.03%0.64% as of December 31, 20152018 from 1.81%0.91% as of December 31, 2014.2017. The ratio of originated commercial real estate loans on nonaccrual to total originated commercial real estate loans increaseddecreased to 0.13%0.14% as of December 31, 20152018 from 0.05%0.16% as of December 31, 2014.2017. The decrease in total criticized and classified commercial real estate loans had a minimal impact on the allowance for commercial real estate loan losses as these loans are adequately collateralized over the loan carrying balance.
Net charge-offs was $0.6 million,increased $85.0 thousand to $103.0 thousand, or 0.02%0.003% of average commercial real estate loans, for the year ended December 31, 2015. As a percentage2018, compared with net charge-offs of $18.0 thousand, or 0.001% of average commercial real estate loans, net charge-offs for the year ended December 31, 20142017. The increase in net charge-offs was negligible.primarily due to the charge-off of an acquired commercial real estate relationship. Provisions for commercial real estate loans recorded in these periods more than adequately covered charge-offs during those periods. See the "Results of Operations—Provision for Credit Losses" section below for additional information.
Commercial Loans and Leases
The allowance for commercial loan and lease losses was $22.0$25.3 million, or 1.60%1.43% of total commercial loans and leases outstanding, as of December 31, 2015,2018, compared to $16.0$26.3 million, or 1.37%1.62% of total commercial loans and leases outstanding, as of December 31, 2014.2017. Specific reserves on commercial loans and leases increaseddecreased from $1.0$3.1 million as of December 31, 20142017 to $1.3$3.0 million as of December 31, 2015.2018. The $6.1$1.0 million increasedecrease in the allowance for commercial loans and lease losses during 20152018 was primarily driven by the decrease in historical loss factors applied to the commercial loan and lease portfolios, partially offset by the reserve for originated loan growth of $247.6$130.5 million, or 22.5%, and the deterioration of one relationship in the commercial loans and leases portfolio during the first quarter of 2015.8.1% from December 31, 2017.
The ratio of total criticized and classified commercial loans and leases to total commercial loans and leases was 1.57%decreased to 2.10% as of December 31, 2015, compared to 2.28%2018, from 2.47% as of December 31, 2014.2017. The ratio of originated commercial loans and leases on nonaccrual to total originated commercial loans and leases decreased to 0.46%0.93% as of December 31, 20152018 from 0.54%1.15% as of December 31, 2014.2017. The decreases in the ratio of total criticized and classified commercial loans and leases to total commercial loans and leases and the ratio of originated commercial loans and leases on nonaccrual to total originated commercial loans and leases was primarily due to the charge-offs and payoffs on criticized commercial loans in 2018.
Net charge-offs increased $1.3decreased $9.5 million to $3.0$4.3 million, or 0.23%0.25% of average commercial loans and leases, for the year ended December 31, 2015,2018, compared with net charge-offs of $1.7$13.8 million, or 0.16%0.88% of average commercial loans and leases, for the year ended December 31, 2014.2017.

Provisions for commercial loans recorded in these periods more than adequately covered charge-offs during those periods. See the "Results of Operations—Provision for Credit Losses" section below for additional information.
Indirect Automobile Loans

Loans outstanding decreased $303.3 million, or 95.7%, to $13.7 million as of December 31, 2015 from $317.0 million as of December 31, 2014. Based on a review of the credit metrics of the remaining indirect automobile portfolio, and a change in the reserve factor, the allowance ratio increased for the remaining portfolio. There were no loans individually evaluated for impairment in the indirect automobile portfolio as of December 31, 2015 and December 31, 2014.
The ratio of indirect automobile loans with borrower credit scores below 660 to the total indirect automobile portfolio increased to 45.5% as of December 31, 2015 from 3.1% as of December 31, 2014.

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 $4.3$5.2 million, or 0.46%0.44% of total consumer loans outstanding, as of December 31, 2015,2018, compared to $3.4$5.1 million, or 0.39%0.50% of consumer loans outstanding, as of December 31, 2014. There was nominal reserve for2017. Specific reserves on consumer loans individually evaluated for impairmentwere $115.0 thousand and $22.0 thousand as of December 31, 20152018 and 2014.December 31, 2017, respectively. The $0.9$0.1 million increase in the allowance for consumer loans and leases during 20152018 was primarily driven bydue to the originated loan growth of $109.4$73.6 million, or 16.4%7.9%, from December 31, 2014. 2017.
The ratio of originated consumer loans on nonaccrual to total originated consumer loans increaseddecreased to 0.29%0.20% as of December 31, 20152018 from 0.23% as of December 31, 2014.2017. The risk of loss on a home equity loan is higher since the property securing the loan has often been previously pledged as collateral for a first mortgage loan. The Company gathers and analyzes delinquency data, to the extent that data are available on these first liens, for purposes of assessing the collectability of the second liens held by the Company even if these home equity loans are not delinquent. This data are further analyzed for performance differences between amortizing and non-amortizing home equity loans, the percentage borrowed to total loan commitment and by the amount of payments made by the borrowers. The loss exposure is not considered to be high due to the

combination of current property values, the historically low loan-to-value ratios, the low level of losses experienced in the past few years and the low level of loan delinquencies as of December 31, 2015.2018. If the local economy weakens, however, a rise in losses in those loan classes could occur. Historically, losses in these classes have been low.
Net charge-offs in the consumer loan portfolio totaled $0.5$0.3 million, or 0.05%0.03% of average consumer loans, for the year ended December 31, 2015,2018, compared with net charge-offs of $0.5$0.1 million, or 0.06%0.01% of average consumer loans, for the year ended December 31, 2014.
Unallocated Allowance

See the "Results of the changes to the methodology described above, the reserveOperations—Provision for unallocated allowanceCredit Losses" section below for loan and lease losses as of December 31, 2015 was reduced to zero, as compared to $2.4 million as of December 31, 2014.additional information.

Investment securities are utilized as part of the Company's asset/liability management and may be sold in response to, or in anticipation of, factors such as changes in market conditions and interest rates, security prepayment rates, deposit outflows, liquidity concentrations and regulatory capital requirements.
The investment policy of the Company, which is reviewed and approved by the Board of Directors on an annual basis, specifies the types of investments that are acceptable, required investment ratings by at least one nationally recognized rating agency, concentration limits and duration guidelines. Compliance with the investment policy is monitored on a regular basis. In general, the Company seeks to maintain a high degree of liquidity and targets cash, cash equivalents and investment securities available-for-sale balances between 10% and 30% of total assets.

Total investment securities and restricted equity securities primarily consist of investment securities available-for-sale, investment securities held-to-maturity, stock in the FHLBB and stock in the FRB. The total securities portfolio increased $47.0$29.9 million, or 7.5%4.2% since December 31, 2014.2017. As of December 31, 2015,2018, total securities portfolio was 11.1%9.19% of total assets, compared to 10.8%10.46% of total assets as of December 31, 2014.2017.
The fair value of investment securities is based principally on market prices and dealer quotes received from third-party, nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's marketable equity securities held-for-trading are priced this way and are included in Level 1. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include certain U.S. and government agency debt securities, municipal and corporate debt securities, GSE residential MBSs and CMOs, and trust preferred securities, and equity securities held-for-trading, all of

45


which are included in Level 2. Certain fair values are estimated using pricing models (such as auction-rate municipal securities)1 and are included in Level 3.2.

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

Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for the particular security.

During the second quarter of 2014, to better align the Company’s investment portfolio with Management’s strategic focus, the Company liquidated all private-label CMOs, auction-rate municipal obligations and municipal obligations, all of which are 100% risk weighted. Proceeds from the investment securities sales were used to reinvest in GSE securities, which are risk weighted at 20%.

Maturities, calls and principal repayments for investment securities available-for-sale and investment securities held-to-maturity totaled $107.4$86.2 million for the year ended December 31, 20152018 compared to $84.6$75.4 million for the same period in 2014. There were no sales2017. The Company sold $22.2 million of investment securities available-for-sale in 2015, as2018, compared to sales of $5.5 millionnone in investment securities available-for-sale and gains of $0.1 million for 2014.2017. For the year ended December 31, 2015,2018, the Company purchased $63.6$73.9 million of investment securities available-for-sale and $102.8$8.9 million of investment securities held-to-maturity, compared to $139.9$91.0 million of investment securities available-for-sale and $0.5$26.9 million of investment securities held-to-maturity in 2014.2017.
As of December 31, 2015,2018, the fair value of all investment securities available-for-sale was $513.2$502.8 million and carried a total of $4.4$12.5 million of net unrealized losses, compared to a fair value of $550.8$540.1 million and net unrealized losses of $2.8$7.8 million as of December 31, 2014.2017. As of December 31, 2015, $368.62018, $466.7 million, or 71.8%92.8%, of the portfolio, had gross unrealized losses of $6.0$12.8 million. This compares to $335.7$469.2 million, or 60.9%86.9%, of the portfolio with gross unrealized losses of $6.0$8.4 million as of December 31, 2014.2017. The Company's unrealized loss position increased in 20152018 driven by a higher year over year interest rates and a change in the portfolio mix from shorter duration MBS to longer duration agency debentures and municipal securities.
Management believes that these negative differences between amortized cost and fair value do not include credit losses, but rather differences in interest rates between the time of purchase and the time of measurement. It is more likely than not that the Company will not sell the investment securities before recovery, and, as a result, it will recover the amortized cost basis of the investment securities. As such, Managementmanagement has determined that the securities are not other-than-temporarily impaired as of December 31, 2015.2018. 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 21, “Fair Value of Financial Instruments.”

Mortgage-related securities are created by the pooling of mortgages and the issuance of a security with an interest rate that is less than the average interest rate on the underlying mortgages. Mortgage related securities purchased by the Company generally are comprised of a pool of single-family mortgages. The issuers of such securities are generally GSEs such as FNMA, FHLMC and GNMA, which pool and resell participation interests in the form of securities to investors and guarantee the payment of principal and interest to the investors.

Investments in mortgage-related securities issued and guaranteed by GSEs generally do not entail significant credit risk. Such investments, however, are susceptible to significant interest rate and cash flow risks when actual cash flows from the investments differ from cash flows estimated at the time of purchase. Additionally, the market value of such securities can be affected adversely by market changes in interest rates. Prepayments that are faster than anticipated may shorten the life of a security and result in the accelerated expensing of any premiums paid, thereby reducing the net yield earned on the
security. Although prepayments of underlying mortgages depend on many factors, the difference between the interest rates on the underlying mortgages and prevailing mortgage interest rates generally is the most significant determinant of the rate of prepayments. During periods of declining interest rates, refinancing generally increases and accelerates the prepayment of underlying mortgages and the related security. Such an occurrence can also create reinvestment risk because of the unavailability of other investments with a comparable rate of return in relation to the nature and maturity of the alternative investment. Conversely, in a rising interest-rate environment, prepayments may decline, thereby extending the estimated life of the security and depriving the Company of the ability to reinvest cash flows at the higher market rates of interest.

The Company's growth in deposits and the shift in the mix of deposits in 20152018 and 20142017 were due in part to expansion of the Company's cash management services and increased efforts in seeking deposits from existing customer relationships. 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.

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

FHLBB borrowings decreased by $142.2$105.5 million to $0.9 billion$784.4 million as of December 31, 20152018 from the December 31, 20142017 balance of $1.0 billion.$889.9 million. The decrease in FHLBB borrowings was primarily due to maturities ofmaturing advances from the FHLBB.
Repurchase AgreementsOther Borrowed Funds
In addition to advances from the FHLBB and subordinated debentures and notes, the Company utilizes other funding
sources as part of the overall liquidity strategy. Those funding sources include repurchase agreements, committed and uncommitted lines of credit with several financial institutions.

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 repurchaseRepurchase agreements with Company customers decreased $1.4increased
$15.1 million to $38.2$52.7 million as of December 31, 20152018 from $39.6$37.6 million as of December 31, 2014.2017.

The Company has access to a $12.0 million committed line of credit as of December 31, 2018. As of December 31, 2018 and December 31, 2017, the Company did not have any borrowings on this committed line of credit outstanding.

The Banks also have access to funding through several uncommitted lines of credit of $370.0 million. As of
December 31, 2018 the Company had no borrowings on outstanding uncommitted lines as compared to December 31, 2017, when the Company had $10.0 million in borrowings on outstanding uncommitted lines.
Subordinated Debentures and Notes
In connection with the acquisition of Bancorp Rhode Island, Inc., the Company assumed three subordinated debentures issued by a subsidiary of Bancorp Rhode Island, Inc. One of these subordinated debenture in the amount of $3.0 million was called in the first quarter of 2013 due to its high fixed rate.
On September 15, 2014, the Company offered $75.0 million of 6.0% fixed-to-floating subordinated notes due September
15, 2029. The Company is obligated to pay 6.0% interest semiannually between September 2014 and September 2024. Subsequently, the Company is obligated to pay 3-month LIBOR plus 3.315% quarterly until the notes mature in September 2029. As of December 31, 2015,2018, the Company had capitalized $1.4costs of $1.1 million in relation to the issuance of these subordinated notes.

Results of Operations
The primary drivers of the Company's net income are net interest income, which is strongly affected by the net yield on and growth of interest-earning assets and liabilities ("net interest margin"), the quality of the Company's assets, its levels of non-interest income and non-interest expense, and its tax provision.
The Company's net interest income represents the difference between interest income earned on its investments, loans and leases, and its cost of funds. Interest income is dependent on the amount of interest-earning assets outstanding during the period and the yield earned thereon. Cost of funds is a function of the average amount of deposits and borrowed money outstanding during the year and the interest rates paid thereon. The net interest margin is calculated by dividing net interest income by average interest-earning assets. Net interest spread is the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities. The increases or decreases, as applicablyapplicable, in the components of interest income and interest expense, expressed in terms of fluctuation in average volume and rate, are

53


summarized under "Rate/Volume Analysis" below. Information as to the components of interest income, interest expense and average rates is provided under "Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin" below.
Because the Company's assets and liabilities are not identical in duration and in repricing dates, the differential between the two is vulnerable to changes in market interest rates as well as the overall shape of the yield curve. These vulnerabilities are inherent to the business of banking and are commonly referred to as "interest-rate risk." How interest-rate risk is measured and, once measured, how much interest-rate risk is taken are based on numerous assumptions and other subjective judgments. See the discussion in the "Measuring Interest-Rate Risk" section of Item 7A, "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.
Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin

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.

Comparison of Years Ended December 31, 20152018 and December 31, 20142017
Net Interest Income
Net interest income increased $5.3$24.5 million to $194.4$247.7 million for the year ended December 31, 20152018 from $189.1$223.2 million for the year ended December 31, 2014.2017. The increase year over year reflects a $5.8$48.2 million increase in interest income on loans and leases, and a $1.9$1.4 million increase in interest income on debt securities, partially offset by a $3.1$26.3 million increase in interest expense on deposit and borrowings, which is reflective of the various portfolios repricing and replacing balances into the current low interest rate environment.
Net interest margin decreasedincreased by 74 basis points to 3.54% in 2015 from 3.61% in 2014. Competitive pressures on loan pricing resulted2018 from 3.57% in decreases in the2017. The Company's weighted average interest rate on loans (prior to purchase accounting adjustments) increased to 4.44%4.84% for the year ended December 31, 20152018 from 4.51%4.47% for the year ended December 31, 2014.2017. Interest amortization and accretion on acquired loans totaled $4.5$0.7 million and contributed 91 basis pointspoint to 20152018 loan yields, compared to $8.4$0.8 million and 161 basis pointspoint in 2014.2017. The decreaseincrease in the net interest margin is the result of repricing and originating interest-earning assets in a lower interesthigher rate environment, without a comparablepartially offset by an increase in lower funding costs.
The yield on interest-earning assets decreasedincreased to 4.12%4.58% for the year ended December 31, 20152018 from 4.19%4.20% for the year ended December 31, 2014.2017. This decreaseincrease is the result of the continued pricing pressure due to the low interest rate environment and the intense competition in most loan categories, as well as a decrease in accretionhigher yields on acquired loans and leases, offset by an increase in prepayment penalties and late charges.leases. During the year ended December 31, 2015,2018, the Company recorded $3.2$3.5 million in prepayment penalties and late charges, which contributed 65 basis points to yields on interest-earning assets in the year ended December 31, 2015,2018 compared to $2.2$3.7 million, or 46 basis points, for the year ended December 31, 2014.

2017.
The overall cost of funds (including non-interest-bearing demand checking accounts) increased 444 basis points to 0.75%1.26% for the year ended December 31, 20152018 from 0.71%0.82% for the year ended December 31, 2014. The increase was primarily driven by the issuance of the $75.0 million subordinated notes in September 2014.2017. Refer to "Financial Condition - Borrowed Funds" above for more details.
FutureManagement seeks to position the balance sheet to be neutral to asset sensitive to changes in interest rates. Since the end of 2016, short term interest rates have risen while at the same time net interest income, net interest spread, and net interest margin may continuehave also increased. In general, the Company's balance sheet position should respond positively in a rising interest rate environment and when the rate curves are steepening which should result in a positive impact to be negatively affected bynet interest income, net interest spread, and the net interest margin. A declining interest rate or flattening yield curve environment is expected to have a number ofnegative impact on the Company's yields and net interest margin. Additional risk factors including: the low interest-rate environment,include, but are not limited to: ongoing pricing pressures in both the loan and deposit portfolios, the ability of the Company to increase itsthe Company's core deposit ratio, the ability of the Company to increase its non-interest-bearing deposits as a percentage of total deposits, decrease its loan-to-deposit ratio, orand decrease its reliance on FHLBB advances. ItNet interest income may also be negatively affected by changes in the amount of purchase accounting accretion on acquired loans and amortizationleases, deposits and borrowed funds, which are included in interest income and interest expense.expense, respectively.

The Company recorded income tax expense of $29.4$26.2 million for 2015,2018, compared to $26.3$43.6 million for 2014.2017. This represents a totalan effective tax ratesrate of 35.9%23.2% and 36.7%44.9% for 20152018 and 2014,2017, respectively. The decrease in the Company's effective tax rate from 20142017 was primarily driven by $10.3 million less in federal income taxes, as a result of the Tax Reform Act, along with a $9.0 million Tax Cuts and Jobs Act adjustment that was made in 2017.
The Tax Reform Act represents the most comprehensive reform to the U.S. tax code in over thirty years. The majority of the provisions of the Tax Reform Act took effect on January 1, 2018. The Tax Reform Act lowered the Company’s federal tax rate from 35% in 2017 to 21% in 2018. The Tax Reform Act also contained other provisions that may affect the Company currently or in future years. Among these are changes to the deductibility of meals and entertainment, the deductibility of executive compensation, accelerated expensing of depreciable property for assets placed in service after September 27, 2017 and before 2023, limited the deductibility of net interest expense, eliminated the corporate alternative minimum tax, limited net operating loss carryforwards to 80% of taxable income and most recently, a parking disallowance related to employee parking.
As a result of the Tax Reform Act, in 2017, management re-valued the carrying value of our net deferred tax asset and investments in municipal bondslow income housing tax credits. The impact of the Tax Reform Act resulted in a write down of the carrying balance of net deferred tax assets and the formationinvestments in affordable housing projects of a new security corporation in Massachusetts.$8.6 million and $0.3 million, respectively.

For the year ended December 31, 2014, netNet interest income increased $12.9$19.5 million to $189.1 million from $176.2$223.2 million for the year ended December 31, 2013.2017 from $203.7 million for the year ended December 31, 2016. The increase year over year increase reflects a $9.7$22.3 million increase in interest income on loans and leases, and a $1.6$0.8 million increase in interest income on debt securities, and lowerpartially offset by a $3.9 million increase in interest expense on depositsdeposit and borrowings, of $0.8 million which is reflective of the various portfolios repricing and replacing balances ininto the current low interest rate environment.
Net interest margin decreasedincreased by 313 basis points to 3.61%3.57% in 20142017 from 3.64%3.44% in 2013. Competitive pressures on loan pricing resulted in a decrease in the2016. The Company's weighted average interest rate on loans (prior to purchase accounting adjustments) increased to 4.49%4.47% for the year ended December 31, 20142017 from 4.66%4.31% for the year ended December 31, 2013.2016. Interest amortization and accretion on acquired loans totaled $8.4$0.8 million and contributed 161 basis pointspoint to 2017 loan yields, in 2014, compared to $4.7$1.5 million and 103 basis points in 2013, primarily due to changes2016. The increase in expected cash flows.the net interest margin is the result of repricing and originating interest-earning assets in a higher rate environment, partially offset by an increase in funding costs.
The decrease in asset yields in 2014 was offset by a decrease in the total cost of interest-bearing liabilities of 7 basis points, the Company's total cost of interest-bearing liabilities was 0.71% in 2014 comparedyield on interest-earning assets increased to 0.78% in 2013. The decrease in the cost of interest-bearing liabilities was driven by a reduction in replacement rates on FHLB borrowings and the interest rates provided4.20% for certain deposit products. The cost of interest-bearing deposits decreased 8 basis points to 0.54% in 2014 from 0.62% in 2013 as customers continued to shift funds from certificates of deposits to non-maturity deposit products. For the year ended December 31, 2014, interest amortization2017 from 4.04% for the year ended December 31, 2016. This increase is the result of higher yields on loans and accretionleases. During the year ended December 31, 2017, the Company recorded $3.7 million in prepayment penalties and late charges, which contributed 6 basis points to yields on purchase accounting marks on borrowedinterest-earning assets in the year ended December 31, 2017 compared to $3.5 million, or 6 basis points, for the year ended December 31, 2016.
The overall cost of funds and certificates of deposits totaled $3.1 million and contributed(including non-interest-bearing demand checking accounts) increased 5 basis points to 0.82% for the 2014 netyear ended December 31, 2017 from 0.77% for the year ended December 31, 2016.

Management seeks to position the balance sheet to be neutral to asset sensitive to changes in interest margin compared to $3.8 million and 8 basis points in 2013.
Futurerates. Since the end of 2016, short term interest rates have risen while at the same time net interest income, net interest spread, and net interest margin may continuehave also increased. In general, the Company's balance sheet position should respond positively in a rising interest rate environment and when the rate curves are steepening, resulting in a positive impact to be negatively affected bynet interest income, net interest spread, and the low interest-ratenet interest margin. A declining interest rate or flattening yield curve environment is expected to have a negative impact on the Company's yields and net interest margin. Additional risk factors include, but are not limited to: ongoing pricing

pressures in both the loan and deposit portfolios, and the ability of the Company to increase itsthe Company's core deposit ratio, increase its non-interest-bearing deposits as a percentage of total deposits, decrease its loan-to-deposit ratio, orand decrease its reliance on FHLBB advances.

This compares to $613.5$601.1 million, or 10.6%8.9% of total assets as of December 31, 2014.2017.
While Managementmanagement 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 Arrangements
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.loan level derivatives. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received. The effect of such activity on the Company's financial condition and results of operations, such as recorded liability for unfunded credit commitment, is immaterial. See Note 13, "Commitments and Contingencies," to the consolidated financial statements for a description of off-balance-sheet financial instruments.

Item 7A.    Quantitative and Qualitative Disclosures about Market Risk
Market Risk
Market risk is the risk that the market value or estimated fair value of the Company's assets, liabilities, and derivative financial instruments will decline as a result of changes in interest rates or financial market volatility, or that the Company's net income will be significantly reduced by interest-rate changes.
Interest-Rate Risk
The principal market risk facing the Company is interest-rate risk, which can occur in a variety of forms, including repricing risk, yield-curve risk, basis risk, and prepayment risk. Repricing risk occurs when the change in the average yield of either interest-earning assets or interest-bearing liabilities is more sensitive than the other to changes in market interest rates. Such a change in sensitivity could reflect a number of possible mismatches in the repricing opportunities of the Company's assets and liabilities. Yield-curve risk reflects the possibility that changes in the shape of the yield curve could have different effects on the Company's assets and liabilities. Basis risk occurs when different parts of the balance sheet are subject to varying base rates reflecting the possibility that the spread from those base rates will deviate. Prepayment risk is associated with financial instruments with an option to prepay before the stated maturity, often a disadvantage to person selling the option; this risk is most often associated with the prepayment of loans, callable investments, and callable borrowings.
Asset/Liability Management
Market risk and interest-rate risk management is governed by the Company's Asset/Liability Committee ("ALCO"). The ALCO establishes exposure limits that define the Company's tolerance for interest-rate risk. The ALCO and the Company's Treasury Group measure and manage the composition of the balance sheet over a range of possible changes in interest rates while remaining responsive to market demand for loan and deposit products. The ALCO monitors current exposures versus limits and reports those results to the Board of Directors. The policy limits and guidelines serve as benchmarks for measuring interest-rate risk and for providing a framework for evaluation and interest-rate risk-management decision-making. The Company measures its interest-rate risk by using an asset/liability simulation model. The model considers several factors to determine the Company's potential exposure to interest-rate risk, including measurement of repricing gaps, duration, convexity, value-at-risk, market value of portfolio equity under assumed changes in the level of interest rates, the shape of yield curves, and general market volatility.
Management controls the Company's interest-rate exposure using several strategies, which include adjusting the maturities of securities in the Company's investment portfolio, limiting or expanding the terms of loans originated, limiting fixed-rate deposits with terms of more than five years, and adjusting maturities of FHLBB advances. The Company limits this risk by restricting the types of MBSs it invests in to those with limited average life changes under certain interest-rate-shock scenarios, or securities with embedded prepayment penalties. The Company also places limits on holdings of fixed-rate mortgage loans with maturities greater than five years. The Company may also use derivative instruments, principally interest-rate swaps, to manage its interest-rate risk; however, the Company had no derivative fair value hedges or derivative cash flows hedges as of December 31, 20152018 or 2014.2017. See Note 16, "Derivatives and Hedging Activities," to the consolidated financial statements.
Measuring Interest-Rate Risk
As noted above, interest-rate risk can be measured by analyzing the extent to which the repricing of assets and liabilities are mismatched to create an interest-rate sensitivity gap. An asset or liability is said to be interest-rate sensitive within a specific period if it will mature or reprice within that period. The interest-rate sensitivity gap is defined as the difference between the amount of interest-earning assets maturing or repricing within a specific time period and the amount of interest-bearing liabilities maturing or repricing within that same time period. A gap is considered positive when the amount of interest-rate-sensitive assets exceeds the amount of interest-rate-sensitive liabilities. A gap is considered negative when the amount of interest-rate-sensitive liabilities exceeds the amount of interest-rate-sensitive assets. During a period of falling interest rates, therefore, a positive gap would tend to adversely affect net interest income. Conversely, during a period of rising interest rates, a positive gap position would tend to result in an increase in net interest income.
The Company's interest-rate risk position is measured using both income simulation and interest-rate sensitivity "gap" analysis. Income simulation is the primary tool for measuring the interest-rate risk inherent in the Company's balance sheet at a given point in time by showing the effect on net interest income, over a twelve-month period, of a variety of interest-rate shocks. These simulations take into account repricing, maturity, and prepayment characteristics of individual products. The ALCO reviews simulation results to determine whether exposure resulting from changes in market interest rates remains within established tolerance levels over a twelve-month horizon, and develops appropriate strategies to manage this exposure. The Company's interest-rate risk analysis remains modestly asset-sensitive as of December 31, 2015.2018.

The assumptions used in the Company’s interest-rate sensitivity simulation discussed above are inherently uncertain and, as a result, the simulations cannot precisely measure net interest income or precisely predict the impact of changes in interest rates.
As of December 31, 2015,2018, net interest income simulation indicated that the Company's exposure to changing interest rates was within tolerance. The ALCO reviews the methodology utilized for calculating interest-rate risk exposure and may periodically adopt modifications to this methodology. The following table presents the estimated impact of interest-rate changes on the Company's estimated net interest income over the twelve-month periods indicated:

The estimated impact of a 300 basis points increase in market interest rates on the Company's estimated net interest income over a twelve-month horizon was a positive 5.9%8.0% as of December 31, 2015,2018, compared to a positive 1.0%4.9% as of December 31, 2014,2017, the increase in asset sensitivity was due to a change in the funding mix, as deposits replaced wholesale funding.

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

EVE at Risk is calculated by estimating the net present value of all future cash flows from existing assets and liabilities using current interest rates as well as parallel shocks to the current interest-rate environment. The following table sets forth the estimated percentage change in the Company’s EVE at Risk, assuming various shifts in interest rates. Given the interest rate environment as of December 31, 2015,2018, simulations for interest rate declines of more than 100 basis points were not deemed to be meaningful.
 Estimated Percent Change in Economic Value of Equity Estimated Percent Change in Economic Value of Equity
Parallel Shock in Interest Rate Levels At December 31, 2015 At December 31, 2014 At December 31, 2018 At December 31, 2017
Up 300 basis points 7.1 % (2.6)% 2.5 % (0.7)%

Down 100 basis points (7.7)% (5.4)% (7.0)% (7.1)%

The Company's EVE sensitivity for Up shock scenarios increased from December 31, 2017 to December 31, 2018 due to the issuance of common stock which replaced short wholesale funding as well as the duration of assets shortened due to increased prepayments driven by lower, long term rates.


The Company also uses interest-rate sensitivity "gap" analysis to provide a more general overview of its interest-rate risk profile. The interest-rate sensitivity gap is defined as the difference between interest-earning assets and interest-bearing liabilities maturing or repricing within a given time period. The table below shows the Company's interest-rate sensitivity gap position as of December 31, 2015.2018.

As of December 31, 2015,2018, interest-earning assets maturing or repricing within one year amounted to $2.7$3.4 billion and interest-bearing liabilities maturing or repricing within one year amounted to $2.9$3.4 billion, resulting in a cumulative one-year negativepositive gap position of $214.1$12.4 million or 3.79%0.18% of total interest-earning assets. As of December 31, 2014,2017, the Company had a cumulative one-year negativepositive gap position of $371.2$21.0 million, or 6.88%0.33% of total interest-earning assets. The change in the cumulative one-year gap position from December 31, 20142017 was due to increased FHLB borrowings.an increase in short term commercial and commercial real estate loans.
Interest rates paid on NOW accounts, savings accounts and money market accounts are subject to change at any time and such deposits are available for immediate withdrawal. A review of rates paid on these deposit categories over the last several years indicated that the amount and timing of rate changes did not coincide with the amount and timing of rate changes on other deposits when the FRB adjusted its benchmark federal funds rate.
Management views NOW and savings accounts to be less sensitive to interest rates than money market accounts and these accounts are therefore characterized as stable long-term funding sensitive beyond five years. Management views money

market accounts to be more volatile deposits and these accounts are therefore characterized as sensitive to changes in interest rates within the first year.

Item 9A.    Controls and Procedures
Under the supervision and with the participation of the Company's Management,management, including the Company's Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), the Company has evaluated the effectiveness of its disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded 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,management, including its Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
There has been no change in the Company's internal control over financial reporting identified in connection with the quarterly evaluation that occurred during the Company's last fiscal quarter that has materially and detrimentally affected, or is reasonably likely to materially and detrimentally affect, the Company's internal control over financial reporting.
The Company's Managementmanagement 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 Managementmanagement 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 Managementmanagement assessed the effectiveness of its internal control over financial reporting as of the end of the period covered by this report. In addition, the effectiveness of the Company's internal control over financial reporting as of the end of the period covered by this report has been audited by KPMG LLP, an independent registered public accounting firm as stated in its report which is included in Item 8 of this Annual Report on Form 10-K.
On May 14, 2013, the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) issued an updated version of its Internal Control - Integrated Framework, referred to as the 2013 COSO Framework. Management assessed the Company’s system of internal control over financial reporting as of December 31, 2014, in relation to criteria for effective internal control over financial reporting as described in “Internal Control - Integrated Framework (1992),” issued by COSO. Management has adopted the 2013 COSO Framework and deemed the change from the 1992 COSO Framework to the 2013 COSO Framework not significant to the Company’s system of internal control over financial reporting.
Management's Report on Internal Control Over Financial Reporting as of December 31, 20152018 appears on page F-1 herein and the related Report of Independent Registered Public Accounting Firm thereon appears on page F-2 herein.

MANAGEMENT'S REPORT ON INTERNAL CONTROL
OVER FINANCIAL REPORTING
The Managementmanagement of Brookline Bancorp, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting. Brookline Bancorp Inc.'s internal control system was designed to provide reasonable assurance to the Company's Managementmanagement and 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.
Brookline Bancorp, Inc.'s Managementmanagement assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2015.2018. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013). Based on our assessment, we believe that, as of December 31, 2015,2018, the Company's internal control over financial reporting is effective based on those criteria.
Brookline Bancorp, Inc.'s independent registered public accounting firm has issued an audit report on the effectiveness of the Company's internal control over financial reporting. This report appears on page F-2.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements of income, comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the three‑year period ended December 31, 2018, and the related notes (collectively, the consolidated financial statements), and our report dated February 28, 2019 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s Managementmanagement is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’sManagement Report on Effectiveness of Internal Control Over Financial Reporting.Reporting and Compliance with Designated Laws and Regulations. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

(1) Basis of Presentation
Overview
Brookline Bancorp, Inc. (the "Company") is a bank holding company (within the meaning of the Bank Holding Company Act of 1956, as amended) and the parent of Brookline Bank, a Massachusetts-chartered savings bank; Bank Rhode Island ("BankRI"), a Rhode Island-chartered financial institution; and First Ipswich Bank ("First Ipswich"), a Massachusetts-chartered trust company (collectively referred to as the "Banks"). The Banks are all members of the Federal Reserve System. The Company is also the parent of Brookline Securities Corp. ("BSC"). The Company's primary business is to provide commercial, business and retail banking services to its corporate, municipal and individualretail customers through the Banks and its banks and non-bank subsidiaries.
On March 1, 2018, the Company completed the Transaction of First Commons Bank. First Commons Bank was merged with and into Brookline Bank. First Commons Bank had two branch locations in Newton Centre and Wellesley, Massachusetts. These branch locations were closed on June 1, 2018 and consolidated into Brookline Bank's existing branch locations in Newton Centre and Wellesley. The Transaction included $262.3 million in loans and $273.7 million in deposits at fair value. The Transaction qualified as a tax-free reorganization for federal income tax purposes. The total Transaction consideration was $56.0 million. For each share of the Company's common stock, First Commons Bank shareholders received the right to receive 1.089 shares of the Company's common stock with cash in lieu of fractional shares, options, and warrants, resulting in a total cash consideration payment of $851 thousand and an increase in the Company's outstanding shares of 3,481,477 shares.
Brookline Bank, which includes its wholly-owned subsidiaries BBS Investment Corp., Longwood Securities Corp., and its 84.5%-owned84.07% owned subsidiary, Eastern Funding LLC ("Eastern Funding"), operates 25 full-service banking offices in the greater Boston metropolitan area.area with two additional lending offices.

The Company also provides specialty equipment financing through its subsidiaries Eastern Funding, which is based in New York City, New York, and Macrolease, which is based in Plainview, New York. The Company ceased the origination of indirect automobile loans in December 2014.
The Company and the Banks are supervised, examined and regulated by the Board of Governors of the Federal Reserve System ("FRB"). As a Massachusetts-chartered savings bank and trust company respectively, Brookline Bank and First Ipswich respectively, are also subject to regulation under the laws of the Commonwealth of Massachusetts and the jurisdiction of the Massachusetts Division of Banks. As a Rhode Island-chartered financial institution, BankRI is subject to regulation under the laws of the State of Rhode Island and the jurisdiction of the Banking Division of the Rhode Island Department of Business Regulation.
The Federal Deposit Insurance Corporation ("FDIC") offers insurance coverage on all deposits up to $250,000 per depositor at each of the Banks. As FDIC-insured depository institutions, the Banks are also secondarily subject to supervision, examination and regulation by the FDIC. Additionally, as a Massachusetts-chartered savings bank, the deposits of Brookline Bank is alsoare 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 Company's consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") as set forth by the Financial Accounting Standards Board ("FASB") in its Accounting Standards Codification and through the rules and interpretive releases of the Securities and Exchange Commission ("SEC") under the authority of federal securities laws.
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

In preparing these consolidated financial statements, Managementmanagement 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 changechanges 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 and the review of deferred tax assets for valuation allowance.

F-12

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)
December 31, 2015, 2014, 2013

The judgments used by Managementmanagement 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. Except for the adoption of Accounting Standards Update ("ASU") 2014-01, there were no changes to stockholders' equity and net income reported. Refer to Note 10, "Other Assets" for the impact the adoption had on the Company's financial statements.
Cash and Cash Equivalents
For purposes of reporting asset balances and cash flows, cash and cash equivalents includes cash on hand and due from banks (including cash items in process of clearing), interest-bearing deposits with banks, federal funds sold, money market mutual funds and other short-term investments with original maturities of three months or less.
Investment Securities
Investment securities, other than those reported as short-term investments, are classified at the time of purchase as "available-for-sale," "held-to-maturity," or "held-to-maturity."held-for-trading." Classification is periodically re-evaluated for consistency with the Company's goals and objectives. Equity investments in the Federal Home Loan Bank of Boston ("FHLBB") and, the Federal Reserve Bank of Boston and other restricted equities are discussed in more detail in Note 5, "Restricted Equity Securities."
Investment Securities Available-for-Sale, Held-to-Maturity, and Held-to-MaturityHeld-for-Trading
Investment securities for which the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and carried at amortized cost. Those investment securities held for indefinite periods of time but not necessarily to maturity are classified as available-for-sale. Investment securities held for indefinite periods of time include investment securities that Managementmanagement intends to use as part of its asset/liability, liquidity, and/or capital management strategies and may be sold in response to changes in interest rates, maturities, asset/liability mix, liquidity needs, regulatory capital needs or other business factors. Investment securities available-for-sale are carried at estimated fair value, primarily obtained from a third-party pricing service, with unrealized gains and losses reported on an after-tax basis in stockholders' equity as accumulated other comprehensive income or loss. Investment securities expected to be held for very short term duration, used for hedging, or are marketable equity securities are typically designated held-for-trading. Held-for-trading securities are carried at estimated fair value principally based on market prices and dealer quotes received from third-party and nationally-recognized pricing services. Gains and losses for held-for-trading are reported on the income statement as gains on investment securities, net. As of December 31, 20152018 and 2014,2017, the Company did not make any adjustments to the prices provided by the third-party pricing service.
Security transactions are recorded on the trade date. Realized gains and losses are determined using the specific identification method and are recorded in non-interest income. Interest and dividends on securities are recorded using the accrual method. Premiums and discounts on securities are amortized or accreted into interest income using the level-yield method over the remaining period to contractual maturity, adjusted for the effect of actual prepayments in the case of mortgage-backed securities ("MBSs") and collateralized mortgage obligations ("CMOs"). These estimates of prepayment assumptions are made based upon the actual performance of the underlying security, current interest rates, the general market consensus regarding changes in mortgage interest rates, the contractual repayment terms of the underlying loans, the priority rights of the investors to the cash flows from the mortgage securities and other economic conditions. When differences arise between anticipated prepayments and actual prepayments, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. Unamortized premium or discount is adjusted to the amount that would have existed had the new effective yield been applied since purchase, with a corresponding charge or credit to interest income.

F-13

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

Management evaluates securities for other-than-temporary impairment ("OTTI") on a periodic basis. Factors considered in determining whether an impairment is OTTI include: (1) the length of time and the extent to which the fair value has been less than amortized cost, (2) projected future cash flows, (3) the financial condition and near-term prospects of the issuers, and (4) the intent and ability of the Company to hold the investment for a period of time sufficient to allow for any anticipated recovery in fair value. The Company records an OTTI loss in an amount equal to the entire difference between the fair value and amortized cost if: (1) the Company intends to sell an impaired investment security, (2) it is more likely than not that the Company will be required to sell the investment security before its amortized costs,cost, or (3) for debt securities, the present value of expected future cash flows is not sufficient to recover the entire amortized cost basis. If an investment security is determined

F-13

Notes to Consolidated Financial Statements (Continued)
December 31, 2015, 2014, 2013

to be OTTI but the Company does not intend to sell the investment security, only the credit portion of the estimated loss is recognized in earnings, with the non credit portion of the loss recognized in other comprehensive income.
Restricted Equity Securities
The Company invests in the stock of the FHLBB, the Federal Reserve Bank of Boston and a small amount of other restricted securities. No ready market exists for these stocks, and they have no quoted market values. The Banks, as members of the FHLBB, are required to maintain investments in the capital stock of the FHLBB equal to their membership base investments plus an activity-based investment determined according to the Banks' level of outstanding FHLBB advances. Federal Reserve Bank of Boston stock was purchased at par and is redeemable at par. The Company reviews for impairment of these securities based on the ultimate recoverability of the cost basis in the stock. As of December 31, 20152018 and 2014,2017, no impairment has been recognized.
Loans
Originated Loans
Loans the Company originates for the portfolio, and for which it has the intent and ability to hold to maturity, are reported at amortized cost, inclusive of deferred loan origination fees and expenses, less unadvanced funds due borrowers on loans and the allowance for loan and lease losses.
Interest income on loans and leases originated for the portfolio is accrued on unpaid principal balances as earned. Loan origination fees and direct loan origination costs are deferred, and the net fee or cost is recognized in interest income using the interest method. Deferred amounts are recognized for fixed-rate loans over the contractual life of the loans and for adjustable-rate loans over the period of time required to adjust the contractual interest rate to a yield approximating a market rate at the origination date. If a loan is prepaid, the unamortized portion of the loan origination costs, including third party referral related costs not subject to rebate from the dealer, is charged to income.
Loans and Leases Held-for-Sale
Management identifies and designates certain newly originated loans and leases for sale to specific financial institutions, subject to the underwriting criteria of those financial institutions. These loans and leases are held for sale and are carried at the lower of cost or market as determined in the aggregate. Deferred loan fees and costs are included in the determination of the gain or loss on sale.
Acquired Loans
Acquired loans that have evidence of deterioration of credit quality since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually required payments receivable are initially recorded at fair value (as determined by the present value of expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected at acquisition and the recorded fair value of the loan, or the “accretable yield,” is recognized as interest income on a level-yield method over the life of the loan. Contractually required payments for interest and principal that exceed the undiscounted cash flows expected at acquisition, or the “nonaccretable difference,” are not recognized as a yield adjustment or as a loss accrual or a valuation allowance. Increases in expected cash flows subsequent to the initial investment are recognized prospectively through adjustment of the yield on the loan over its remaining life. Decreases in expected cash flows are recognized as impairment. Valuation allowances on these impaired loans reflect only losses incurred after the acquisition (meaning the present value of all cash flows expected at acquisition that ultimately are not to be received).
For the First Commons Bank portfolio, minimal loss is expected from the loan portfolio based on historical performance, management’s due diligence, and market conditions. Therefore, the fair value of the loan portfolio was calculated on an individual

loan basis using a discounted cash flow analysis factoring in the contractual terms of the loans, current market pricing, and prepayment expectations.
Nonperforming Loans
Nonaccrual Loans
Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in Management'smanagement's judgment, reasonable doubt exists as to the full timely collection of interest. Exceptions may be made if the loan has matured and is in the process of renewal or is well-secured and in the process of collection. When a loan is placed on nonaccrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current interest income. Interest payments on nonaccrual loans are generally applied to principal. If collection of the principal is reasonably assured, interest payments are recognized as income on the cash basis. Loans are generally returned to accrual status

F-14

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)
December 31, 2015, 2014, 2013

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.
Impaired Loans
A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Smaller-balance, homogeneous loans that are evaluated collectively for impairment, such as residential, home equity and other consumer loans are specifically excluded from the impaired loan portfolio except where the loan is classified as a troubled debt restructuring. The Company has defined the population of impaired loans to include nonaccrual loans and troubled debt restructured ("TDR") loans.
When the ultimate collectability of the total principal of an impaired loan or lease is in doubt and the loan is on nonaccrual status, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan or lease is not in doubt and the loan or lease is on nonaccrual status, contractual interest is credited to interest income when received, under the cash basis method.
The value of an impaired loan is measured based upon the present value of expected future cash flows discounted at the loan's effective interest rate, or the fair value of the collateral if the loan is collateral-dependent and its payment is expected solely based on the underlying collateral. For impaired loans deemed collateral dependent, where impairment is measured using the fair value of the collateral, the Company will either obtain a new appraisal or use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral.
Interest collected on impaired loans is either applied against principal or reported as income according to Management'smanagement's judgment as to the collectability of principal. If Managementmanagement does not consider a loan ultimately collectible within an acceptable time frame, payments are applied as principal to reduce the loan balance. If full collection of the remaining recorded investment should subsequently occur, interest receipts are recorded as interest income on a cash basis.
Troubled Debt Restructured Loans
In cases where a borrower experiences financial difficulties and the Company makes certain concessionary modifications to contractual terms, the loan is classified as a TDR loan. In determining whether a debtor is experiencing financial difficulties, the Company considers, among other factors, whether the debtor is in payment default or is likely to be in payment default in the foreseeable future without the modification, if the debtor declared or is in the process of declaring bankruptcy, there is substantial doubt that the debtor will continue as a going concern, the debtor's entity-specific projected cash flows will not be sufficient to service its debt, or the debtor cannot obtain funds from sources other than the existing creditors at market terms for debt with similar risk characteristics.
Large groups of small-balance homogeneous loans such as residential real estate, residential construction, home equity and other consumer portfolios are collectively evaluated for impairment. As such, the Company does not typically identify individual loans within these groupings as impaired loans or for impairment evaluation and disclosure. However, the Company evaluates all TDRs for impairment on an individual loan basis regardless of loan type.
Modifications may include interest-rate reductions, short-term (defined as one year or less) changes in payment structure to interest-only payments, short-term extensions of the loan's original contractual term, or less frequently, principal forgiveness, interest capitalization, forbearance and other actions intended to minimize economic loss and avoid foreclosure or repossession

F-15

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

of collateral. Typically, TDRs are placed on nonaccrual status and reported as nonperforming loans. Generally, a nonaccrual loan that is restructured remains on nonaccrual for a period of six months to demonstrate that the borrower can meet the restructured terms; however, performance prior to the restructuring, or significant events that coincide with the restructuring, are considered in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual status at the time of restructuring or after a shorter performance period. If the borrower's ability to meet the revised payment schedule is not reasonably assured, the loan remains classified as a nonaccrual loan.
Loans restructured at an interest rate equal to or greater than that of a new loan with comparable risk at the time the loan agreement is modified may be excluded from restructured loan disclosures in years subsequent to the restructuring if they are in compliance with the modified terms.
Allowance for Loan and Lease Losses

F-15

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)
December 31, 2015, 2014, 2013

Management has established a methodology to determine the adequacy of the allowance for loan and lease losses that assesses the risks and losses inherent in the loan and lease portfolio. Additions to the allowance for loan and lease losses are made by charges to the provision for credit losses. Losses on loans and leases are charged off against the allowance when all or a portion of a loan or lease is considered uncollectible. Subsequent recoveries on loans previously charged off, if any, are credited to the allowance when realized.
Management uses a consistent and systematic process and methodology to evaluate the adequacy of the allowance for loan and lease losses on a quarterly basis. For purposes of determining the allowance for loan and lease losses, the Company has segmented certain loans and leases in the portfolio by product type into the following segments: (1) commercial real estate loans, (2) commercial loans and leases, (3) and 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 which includes taxi medallion loans, equipment financing, and loans to condominium associations. Consumer loans are divided into fourthree classes: residential mortgage loans, home equity loans, indirect automobile loans, and other consumer loans. A formula-based credit evaluation approach is applied to each group, coupled with an analysis of certain loans for impairment.
 The general allowance related to loans collectively evaluated for impairment is determined using a formula-based approach utilizing the risk ratings of individual credits and loss factors derived from historic portfolio loss rates, which include estimates of incurred losses over an estimated loss emergence period (“LEP”). The LEP was generated utilizing a charge-off look-back analysis which studied the time from the first indication of elevated risk of repayment (or other early event indicating a problem) to eventual charge-off to support the LEP considered in the allowance calculation. This reserving methodology established the approximate number of months of LEP that represents incurred losses for each portfolio. In addition to quantitative measures, relevant qualitative factors include, but are not limited to: (1) levels and trends in past due and impaired loans, (2) levels and trends in charge-offs, (3) changes in underwriting standards, policy exceptions, and credit policy, (4) experience of lending management and staff, (5) economic trends, (6) industry conditions, (7) effects of changes in credit concentrations, (8) interest rate environment, and (9) regulatory and other changes. The general allowance related to the acquired loans collectively evaluated for impairment is determined based upon the degree, if any, of deterioration in the pooled loans subsequent to acquisition. The qualitative factors used in the determination are the same as those used for originated loans.
During 2015, the Company enhanced and refined its general allowance methodology. Under the enhanced methodology, Managementmanagement combined the historical loss histories of the Banks to generate a single set of historical loss ratios. Management believes it is appropriate to aggregate the ratios as the Banks share common environmental factors, operate in similar geographic markets, and utilize common underwriting standards in accordance with the Company's Credit Policy. In prior periods, a historical loss history applicable to each Bank was used.
Management employed a similar analysis for the consolidation of the qualitative factors as it did for the quantitative factors. Again, Managementmanagement believes the realignment of the existing nine qualitative factors used at each of the Banks into a single group of factors used for the Company is appropriate based on the commonality of environmental factors, markets and underwriting standards among the Banks. In prior periodsPrior to 2015, each of the Banks utilized a set of qualitative factors applicable to each Bank.
The Company’s December 31, 20152018 allowance calculation included a further segmentation of the commercial loans and leases to reflect the increased risk in the Company’s taxi medallion portfolio. As of December 31, 2015,2018, this portfolio is

F-16

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

approximately $35.8$13.7 million. Based on industry conditions, Managementmanagement established a specific loss factor for this portfolio that best represents the changing risks associated with it.
Based on the refinements to the Company’s allowance methodology discussed above, Managementmanagement determined that the potential risks anticipated by the unallocated allowance are now incorporated into the allowance methodology, making the unallocated allowance unnecessary. In prior periods,Prior to 2015, the unallocated allowance was used to recognize the estimated risk associated with the allocated general and specific allowances. It incorporated Management’smanagement’s evaluation of existing conditions that were not included in the allocated allowance determinations and provided for losses that arise outside of the ordinary course of business.
Specific valuation allowances are established for impaired originated loans with book values greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent impaired loans, for any excess of a loan's

book balance and the fair value of its underlying collateral. Specific valuation allowances are established for acquired loans with deterioration in the discounted present value of expected future cash flows since acquisitions or, in the case of collateral dependent impaired loans, for any increase in the excess of a loan's book balance greater than the fair value of its underlying collateral. A specific valuation allowance for losses on TDR loans is determined by comparing the net carrying amount of the troubled debt restructured loan with the restructured loan's cash flows discounted at the original effective rate. Impaired loans are reviewed quarterly with adjustments made to the calculated reserve as necessary.
As of December 31, 2015, Management2018, management believes that the methodology for calculating the allowance is sound and that the allowance provides a reasonable basis for determining and reporting on probable losses in the Company’s loan portfolios.
Liability for Unfunded Commitments
In the ordinary course of business, the Company enters into commitments to extend credit, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded in the financial statements when they become payable. The credit risk associated with these commitments is evaluated in a manner similar to the allowance for loan losses.
Premises and Equipment
Premises and equipment are carried at cost less accumulated depreciation and amortization, except for land which is carried at cost. Premises and equipment are depreciated using the straight-line method over the estimated useful life of the assets. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or the estimated useful life of the improvements.
Costs related to internal-use software development projects that provide significant new functionality are capitalized. Internal-use software is software acquired or modified solely to meet the Company's needs and for which there is no plan to market the software externally. Direct and indirect costs associated with the application development stage of internal use software are capitalized until such time that the software is substantially complete and ready for its intended use. Capitalized costs are amortized on a straight-line basis over the remaining estimated life of the software. Computer software and development costs incurred in the preliminary project stage, as well as training and maintenance costs, are expensed as incurred.
Leases
The Company leases properties for offices and branches in the states of Massachusetts, Rhode Island and New York. Lease terms range from five years to over 25 years with options to renew. Management performs an analysis to determine proper lease accounting at lease inception and for each renewal. If a lease meets any of the following four criteria, the lease is classified as capital lease. The four criteria are: transfer of ownership by the end of lease term; contains bargain purchase option; lease term is at least 75% of the property’s estimated remaining economic life; or present value of the minimum lease payment is at least 90% of the fair value of the leased property. The Company did not have any capital leases as of December 31, 2015 or 2014. All leases are classified as operating leases and rental payments are expensed as incurred. Certain leases contain rent escalation clauses which are amortized over the life of the lease under the straight-line method.
Bank-Owned Life Insurance
The Company acquired bank-owned life insurance ("BOLI") plans as part of its acquisitions of First Ipswich and BankRI. BOLI represents life insurance on the lives of certain current and former employees who have provided positive consent allowing their employer to be the beneficiary of such policies. BankRI and First Ipswich are the beneficiaries of their respective

F-17

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

policies. BankRI and First Ipswich utilize BOLI as tax-efficient financing for their benefit obligations to their employees, including their retirement obligations and Supplemental Executive Retirement Plans ("SERPs").
Since BankRI and First Ipswich are the primary beneficiaries of their respective insurance policies, increases in the cash value of the policies, as well as insurance proceeds received, are recorded in non-interest income and are not subject to income taxes. BOLI is recorded at the cash value of the policies, less any applicable cash surrender charges, and is reflected as an asset in the accompanying consolidated balance sheets. Cash proceeds, if any, are classified as cash flows from investing activities.
The Company reviews the financial strength of the insurance carriers prior to the purchase of BOLI to ensure minimum credit ratings of at least investment grade. The financial strength of the carriers is reviewed at least annually, and BOLI with any individual carrier is limited to 10% of the Company's capital andcapital. Total BOLI is limited to 25% of the Company's capital in the aggregate.capital.

Goodwill and Other Identified Intangible Assets
Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. Goodwill and indefinite-lived identified intangible assets are not subject to amortization. Definite-lived identified intangible assets are assets resulting from acquisitions that are being amortized over their estimated useful lives. The recoverability of goodwill and identified intangible assets is evaluated for impairment at least annually. As part of this evaluation, the Company makes a qualitative assessment of whether it is more likely than not that the fair value of an acquired asset is greater than its carrying amount. If the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is greater than its carrying amount, no further testing is necessary. If, however, the Company qualitatively concludes that it is more likely than not that the fair value of an acquired asset is less than its carrying value, the Company performs a two-step quantitativeshould recognize an impairment test to determine whether the asset is impaired. If impairment is deemed to have occurred,charge for the amount of impairment is charged to expense when identified.by which the carrying amount exceeds the fair value. The Company did not have any impairment of Goodwill and other identified intangible assets as of December 31, 20152018 and 2014.2017.
OREO and Other Repossessed Assets
OREO and other repossessed assets consists of properties acquired through foreclosure, real estate acquired through acceptance of a deed in lieu of foreclosure and loans determined to be substantively repossessed. Real estate loans that are substantively repossessed include only those loans for which the Company has taken possession of the collateral. OREO and other repossessed assets which consist of vehicles and equipment, if any, are recorded initially at estimated fair value less costs to sell, resulting in a new cost basis. The amount by which the recorded investment in the loan exceeds the fair value (net of estimated cost to sell) of the foreclosed or repossessed asset is charged to the allowance for loan and lease losses. Such evaluations are based on an analysis of individual properties/assets as well as a general assessment of current real estate market conditions. Subsequent declines in the fair value of the foreclosed or repossessed asset below the new cost basis are recorded through the use of a valuation allowance. Subsequent increases in the fair value are recorded as reductions in the allowance, but not below zero. Rental revenue received on foreclosed or repossessed assets is included in other non-interest income, whereas operating expenses and changes in the valuation allowance relating to foreclosed and repossessed assets are included in other non-interest expense. Certain costs used to improve such properties are capitalized. Gains and losses from the sale of OREO and other repossessed assets are reflected in non-interest expense when realized. Together with nonperforming loans, OREO and repossessed assets comprise nonperforming assets.
Derivatives
The Company enters intoutilizes loan level derivatives which consists of interest rate swapcontracts (swaps, caps and floors), and risk participation agreements as part of the Company's interest-rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company's intended use for the interest rate swaploan level derivatives at inception, the Company designates the derivative as either an economic hedge of an asset or liability, or a hedging instrument subject to the hedge accounting provisions of FASB ASC Topic 815, "Derivatives and Hedging."
Interest rate swapsLoan level derivatives and foreign exchange contracts entered into on behalf of our customers are designated as economic hedges and are recorded at fair value within other assets or liabilities. Changes in the fair value of these non hedging derivatives are recorded directly through earnings at each reporting period.
Transfer of Financial Assets
Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred

assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Securities Sold under Agreements to Repurchase
The Company enters into sales of securities under agreements to repurchase with the Banks' commercial customers. These agreements are treated as financings, and the obligations to repurchase securities sold are reflected as a liability in the consolidated balance sheets. Securities pledged as collateral under agreements to repurchase are reflected as assets in the accompanying consolidated balance sheets.
Employee Benefits

Costs related to the Company's 401(k) plan are recognized in current operations.earnings. Costs related to the Company's nonqualified deferred compensation plan, SERPs and postretirement benefits are recognized over the vesting period or the related service periods of the participating employees. Changes in the funded status of postretirement benefits are recognized through comprehensive income in the year in which changes occur.
Compensation expense for the Company's Employee Stock Ownership Program ("ESOP") is recorded at an amount equal to the shares allocated by the ESOP multiplied by the average fair market value of the shares during the year. The Company recognizes compensation expense ratably over the year based upon the Company's estimate of the number of shares expected to be allocated by the ESOP. The difference between the average fair market value and the cost of the shares allocated by the ESOP is recorded as an adjustment to additional paid-in capital.
The fair value of restricted stock awards and stock option grants are determined as of the grant date and are recorded as compensation expense over the period in which the shares of restricted stock awards and stock options vest. Forfeitures are estimated in determining compensation expense.accounted for as they occur.
Fair Value Measurements
ASC 820-10, "Fair Value Measurements and Disclosures," defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability is not adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities. It is not a forced transaction. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, able to transact, and willing to transact.
A fair-value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs are included in ASC 820. The fair value hierarchy is as follows:
Level 1: Inputs are unadjusted quoted prices in active markets for assets and liabilities identical to those reported at fair value.
Level 2: Inputs other than quoted prices included within Level 1. Level 2 inputs are observable either directly or indirectly. These inputs might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.
Level 3: Inputs are unobservable inputs for an asset or liability that reflect an entity's own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. These inputs are used to determine fair value only when observable inputs are not available.
Earnings per Common Share
Basic earnings per share ("EPS") is computed by dividing net income by the weighted average number of shares of common stock outstanding for the applicable period, exclusive of Treasury shares, unearned ESOP shares and unvested shares of restricted stock. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all

Notes to Consolidated Financial Statements (Continued)

potential dilutive common shares outstanding during the period. The dilutive effects of options and unvested restricted stock awards are computed using the "treasury stock" method. Management evaluated the "two class" method and concluded that the method did not apply to the Company's EPS calculation.
Income Taxes
Income taxes are accounted for under the asset and liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
Tax positions that are more likely than not to be sustained upon a tax examination are recognized in the Company's financial statements to the extent that the benefit is greater than 50% likely of being recognized. Interest resulting from underpayment of income taxes is classified as income tax expense in the first period the interest would begin accruing according to the provision of the relevant tax law. Penalties resulting from underpayment of income taxes are classified as income tax expense in the period for which the Company claims or expects to claim an uncertain tax position or in the period in which the Company's judgment changes regarding an uncertain tax position.
Treasury Stock
Any shares repurchased under the Company's share repurchase programs were purchased in open-market transactions and are held as treasury stock. Treasury stock also consists of common stock withheld to satisfy federal, state and local income tax withholding requirements for employee restricted stock awards upon vesting. All treasury stock is held at cost.
Segment Reporting
An operating segment is defined as a component of a business for which separate financial information is available that is evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and evaluate performance. The Company is a bank holding company with subsidiaries engaged in the business of banking and activities closely related to banking. The Company's banking business provided substantially all of its total revenues and pre-tax income in 2015, 20142018, 2017 and 2013.2016. Therefore, the Company has determined there to be a single segment.
Recent Accounting Pronouncements
In December 2018, FASB issued ASU 2018-20 Leases (Topic 842), to update provisions to ASU 2016-02, Leases (Topic 842). The first revision is in relation to sales taxes and other similar taxes collected from lessees. The amendments in this update permit lessors, as an accounting policy election, to not evaluate whether certain sales taxes and other similar taxes are lessor costs or lessee costs. Instead, those lessors will account for those costs as if they are lessee costs. The second revision is in relation to certain lessor costs. Certain lessor costs require lessors to exclude from variable payments, and therefore revenue, lessor costs paid by lessees directly to third parties. The amendments also require lessors to account for costs excluded from the consideration of a contract that are paid by the lessor and reimbursed by the lessee as variable payments. The third revision in this update is related to recognizing variable payments for contracts with lease and non-lease components require lessors to allocate certain variable payments to the lease and non-lease components when the changes in facts and circumstances on which the variable payment is based occur. Management has determined that this ASU does apply as of December 31, 2018. Management has assembled a project team that meets regularly to address the changes pursuant to Topic 842. The Company rents premises used in business operations under non-cancelable operating leases, which currently are not reflected in its consolidated balance sheet. As disclosed in Note 13, the Company was committed to $28.4 million of future minimum lease payments under these non-cancelable operating leases. Upon adoption of ASU 2016-02 on January 1, 2019, the Company expects to report increased assets and liabilities of approximately $23.6 million as a result of recognizing right of-use assets and lease liabilities in its consolidated balance sheets. The Company does not expect a material change to the timing of expense recognition in the consolidated statements of income.
In November 2018, FASB issued ASU 2018-19 Codification Improvements to Topic 326 Financial Instruments - Credit Losses, to clarify the Codification or to correct unintended application of guidance within ASU 2016-13 Financial instruments - Credit Losses (Topic 326). This ASU is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. Management has determined that ASU 2018-19 does apply, but

F-20

has not determined the impact, if any, as of December 31, 2018. In preparation for the adoption in 2020 of this ASU, management formed a steering committee to oversee the adoption of ASU 2016-13. The steering committee, along with a project team, has developed an approach for implementation and has selected a third party software service provider. The project team is in the testing phase of the third party software.
In October 2018, FASB issued ASU 2018-16, Derivatives and Hedging (Topic 815), to permit the OIS rate based on SOFR as a U.S. benchmark interest rate. Including the OIS rate based on SOFR as an eligible benchmark interest rate during the early stages of the marketplace transition will facilitate the LIBOR to SOFR transition and provide sufficient lead time for entities to prepare for changes to interest rate risk hedging strategies for both risk management and hedge accounting purposes. This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted in any interim period upon issuance of this update if an entity already has adopted Update ASU 2017-12. Management has determined that this ASU does apply and has not determined the impact, if any, as of December 31, 2018.
In August 2018, FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20), to modify the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. This ASU is effective for fiscal years ending after December 15, 2020, for public business entities and for fiscal years ending after December 15, 2021, for all other entities. Early adoption is permitted. Management believes that this ASU does apply and has not determined the impact, if any, as of December 31, 2018.
In February 2016, the Financial Accounting Standards BoardFASB issued ASU 2016-02, Leases (“FASB”ASU 2016-02”) issued Accounting Standards Update ("ASU") 2016-02, Leases. . This ASU requires lessees to putrecord most leases on their balance sheet but recognize expenses on their income statements in a manner similar to today'scurrent accounting. This ASU also eliminates today'scurrent real estate-specific provisions for all companies. For lessors, this ASU modifies the classification criteria and the accounting for sales-type and direct financing leases. Subsequently, in July 2018, FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases. This ASU iswas issued to clarify the Codification or to correct unintended application of guidance within ASU 2016-02. Also in July 2018, FASB issued ASU 2018-11, “Targeted Improvements” (“ASU 2018-11”), which allows for an optional transition method in which the provisions of Topic 842 would be applied upon the adoption date and would not have to be retroactively applied to the earliest reporting period presented in the consolidated financial statements. ASU 2016-02, 2018-10, and 2018-11 are all effective for fiscal years beginning after December 15, 2018, including interim periods therein. Early adoption is permitted. Management has determined that these ASUs do apply as of December 31, 2018. Management has assembled a project team that meets regularly to address the changes pursuant to Topic 842. The Company rents premises used in business operations under non-cancelable operating leases, which currently are not reflected in its Consolidated Balance Sheet. As disclosed in Note 13, the Company was committed to $28.4 million of future minimum lease payments under these non-cancelable operating leases. Upon adoption of ASU 2016-02 on January 1, 2019, the Company expects to report increased assets and liabilities of approximately $23.6 million as a result of recognizing right of-use assets and lease liabilities in its consolidated balance sheets. The Company does not expect a material change to the timing of expense recognition in the consolidated statements of income.
In August 2018, FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), to modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts in the Concepts Statement, including the consideration of costs and benefits. This ASU is currently assessing the applicability ofeffective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. Management believes that this ASU does apply and has not determined the impact, if any, as of December 31, 2015.2018.
In February 2018, FASB issued ASU 2018-03, Technical Corrections and Improvements to Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. This ASU was issued to add improvements to update ASU 2016-01 to increase stakeholders’ awareness of the amendments and to expedite the improvements. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. Public business entities with fiscal years beginning between December 15, 2017 and June 15, 2018, are not required to adopt these amendments until the interim period beginning after June 15, 2018, and public business entities with fiscal years beginning between June 15, 2018, and December 15, 2018, are not required to adopt these amendments before adopting the amendments in Update 2016-01. Management has determined that ASU 2018-03 does apply and has determined the impact to be immaterial as of December 31, 2018.
In February 2018, the FASB issued Accounting Standards Update (ASU) No. 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income" was issued to address a narrow-scope financial reporting issue that arose as a consequence of the change in the tax law. On December 22, 2017, the U.S. federal government enacted a tax bill, H.R.1, An Act to Provide for Reconciliation Pursuant to

F-21

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 (the “Tax Reform Act”). The ASU No. 2018-02 requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate. The amount of the reclassification would be the difference between the historical corporate income tax rate of 35 percent and the newly enacted 21 percent corporate income tax rate. The ASU No. 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years with early adoption permitted, including adoption in any interim period, for (i) public business entities for reporting periods for which financial statements have not yet been issued and (ii) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The changes are required to be applied retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act of 2017 is recognized. Management early adopted this ASU as of December 31, 2017, which resulted in the reclassification from accumulated other comprehensive loss to retained earnings totaling $1.1 million, reflected in the Consolidated Statements of Changes in Stockholders' Equity.
In November 2017, the FASB issued ASU 2017-14, Income Statement-Reporting Comprehensive Income (Topic 220), Revenue Recognition (Topic 605), and Revenue from Contracts with Customers (Topic 606): Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 116 and SEC Release No. 33-10403. This ASU was issued to amend certain SEC paragraphs pursuant to the SEC Staff Accounting Bulletin No.116 and SEC Release No. 33-10403, which bring existing guidance into conformity with Topic 606, Revenue from Contract with Customers. The ASU was effective for annual periods beginning after December 15, 2017. Management has adopted this ASU as of January 1, 2018 and has determined the impact to be immaterial.
In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. FASB issued this Update to address the diversity in practice as well as the cost and complexity when applying the guidance in Topic 718, Compensation - Stock Compensation, to a change to the terms or conditions of a share-based payment award. For public entities, this ASU is effective for annual reporting periods beginning after December 15, 2017. Management adopted this ASU as of January 1, 2018 and has determined the impact to be immaterial.
In March 2017, the FASB issued Accounting Standards Update ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost (Topic 715). This ASU was issued primarily to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost. This ASU is effective for annual reporting periods beginning after December 15, 2017. Management adopted this ASU as of January 1, 2018 and has determined the impact to be immaterial.
In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). This ASU was issued to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. For public entities, this ASU is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted and application should be on a prospective basis. Management has evaluated this ASU and as of December 31, 2017, the Company has adopted the ASU and determined the impact to be immaterial.
In June 2016, the FASB issued ASU 2016-13, Financial instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The intent of this ASU is to replace the current GAAP method of calculating credit losses. Current GAAP uses a higher threshold at which likely losses can be calculated and recorded. The new process will require institutions to account for likely losses that originally would not have been part of the calculation. The calculation will incorporate future forecasting in addition to historical and current measures. For public entities that file with the SEC, this ASU is effective for the fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. This ASU must be applied prospectively to debt securities marked as other than temporarily impaired. A retrospective approach will be applied cumulatively to retained earnings. Early adoption is permitted as of the fiscal years beginning after December 15, 2018. Management has determined that ASU 2016-13 does apply, but has not determined the impact, if any, as of December 31, 2018. In preparation for the adoption in 2020 of this ASU, management formed a steering committee to oversee the adoption of ASU 2016-13. The steering committee, along with a project team, has developed an approach for implementation and has selected a third party software service provider. The project team is in the testing phase of the third party software.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments. This ASU significantly revises an entity’s accounting related to (1) the classification and measurement of investments in equity securities and (2) the presentation of certain fair value changes for financial liabilities measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial instruments. This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods therein. The Company is currently assessing the applicabilityManagement adopted ASU 2016-01 as of this ASUJanuary 1, 2018 and management has not determined the impact ifto be immaterial.
Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), was issued in May 2014 and provides a revenue recognition framework for any asentity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other accounting standards. As issued, ASU 2014-09 was effective for annual periods beginning after December 31, 2015.

15, 2016, including interim periods within that reporting period with early adoption not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. This ASU was issued to clarify the presentation and subsequent measurement of debt issuance costs related to line-of-credit arrangements, since this was not addressed in the guidance in ASU 2015-03, which requires entities to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. Given the absence of authoritative guidance with ASU 2015-03, ASU 2015-15 states that the SEC staff will not object to an entity deferring and presenting debt issuance costs related to line-of-credit arrangements as an asset and subsequently amortizing the deferred debt issuance costs ratably over the terms of the line-of-credit arrangement. As of December 31, 2015, the Company has accounted for the debt issuance costs related to the line-of-credit arrangement as a reduction of the debt liability, consistent with ASU 2015-03 and with the Company’s accounting treatment for other debt issuance costs. Management has determined that this ASU had no impact to the Company.

In August 2015, the FASB issued ASUAccounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral“Deferral of the Effective Date. This Date” (“ASU 2015-14”) was issued to deferand delayed the effective date of ASU 2014-09 to annual and interim periods in fiscal years beginning after December 15, 2017. In 2016, Accounting Standards Update No. 2016-08, “Principal versus Agent Considerations” (“ASU 2016-08”), Accounting Standards Update No. 2016-10, “Identifying Performance Obligations and Licensing” (“ASU 2016-10”) and Accounting Standards Update No. 2016-12, “Narrow-Scope Improvements and Practical Expedients” (“ASU 2016-12”) were issued. These ASUs did not change the core principle for all entities by one year. In effect, public business entities, certain not-for-profit entities, and certain employee benefit plans should applyrevenue recognition in Topic 606; instead, the amendments provided more detailed guidance in a few areas and additional implementation guidance and examples to reduce the degree of judgment necessary to comply with Topic 606. The effective date and transition requirements for ASU 2016-08, ASU 2016-10 and ASU 2016-12 were the same as those provided by ASU 2015-14. Management assembled a project team to address the changes pursuant to Topic 606. The project team completed a scope assessment and contract review for in-scope revenue streams. Topic 606 did not apply to several income generating streams. Management excluded from their analysis, income associated with financial instruments, gains on sale of investment securities and loans, gains on Low Income Housing Tax Credits ("LIHTC") and loan level derivative income. Revenue streams that were included were service charges on deposit accounts, loan fees, and income received through a third party relationship. Management adopted the provisions of ASU 2014-09 effective January 1, 2018, using the modified retrospective transition method. The adoption did not have a material impact on the Company's consolidated financial statements. See Note 24, "Revenue from Contracts with Customers," for further details.
(2) Acquisitions
First Commons Bank, N.A.
On March 1, 2018, the Company completed the Transaction of First Commons Bank. First Commons Bank was merged with and into the Company’s subsidiary bank, Brookline Bank. First Commons Bank had two branch locations in Newton Centre and Wellesley, Massachusetts. These branch locations were closed on June 1, 2018 and consolidated into Brookline Bank’s existing branch locations in Newton Centre and Wellesley, Massachusetts.
The Transaction qualified as a tax-free reorganization for federal income tax purposes. The total Transaction consideration was $56.0 million. First Commons Bank stockholders received, for each share of First Commons Bank common stock, the right to receive 1.089 shares of the Company’s common stock with cash in lieu of fractional shares, options, and warrants, resulting in a total cash consideration payment of $851 thousand and an increase to the Company’s outstanding shares of 3,481,477 shares.
The Company accounted for the Transaction using the estimated fair value of assets and liabilities assumed as of the acquisition date. The excess of consideration paid over the fair value of identifiable net assets was recorded as goodwill in the consolidated financial statements. Accordingly, the Company recorded merger and acquisition expenses for First Commons Bank of $3.6 million during the twelve months ended December 31, 2018.

This ASU represent changes to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. This ASU is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. All other amendments will be effective upon issuance. Management has determined that this ASU had no impact to the Companyliabilities assumed as of the date of the acquisition:

Fair values of the major categories of assets acquired and liabilities assumed were determined as follows:
Cash and Cash Equivalents
The fair values of cash and cash equivalents approximate the respective carrying amounts because the instruments are payable on demand or have short-term maturities.
Restricted Stock
The fair value of restricted stock approximate the respective carrying amount. The stock is comprised of $880 thousand of FHLBB stock and $1.0 million of FRB stock.
Loans
The loans acquired were recorded at fair value without a carryover of the allowance for loan losses. There were no credit related issues with the acquired portfolio. For the loan purchase accounting, management used the following assumptions: no specific credit mark valuations as determined by the Company's Credit Risk Management, segregation of portfolio into certain loan categories, loan level valuations versus a pooled approach, prepayment rate assumptions and market discount rates.
The Company recorded a $1.6 million discount from the results of the loan accounting valuation. There was $133 thousand and $445 thousand of accretion recorded during the three and twelve months ended December 31, 2015.2018.
Deposits - Core Deposit Intangible ("CDI")
Accounts included in the CDI include demand deposits, NOW accounts, money market accounts and savings accounts. The fair value of the CDI was derived from using the following assumptions: account retention rates, alternative cost of funds, effective cost of funds, cost savings, present value of annual net cost savings and market discount rate.
The Company recorded a $2.1 million CDI from the results of the deposit valuation. There was $123 thousand and $410 thousand of amortization recorded during the three and twelve months ended December 31, 2018.

There was $245 thousand and $817 thousand of amortization recorded during the costs is reported as interest expense. This ASU is applied retrospectively for the first interim or annual period presented beginning after December 15, 2015, early adoption is permitted. As ofthree and twelve months ended December 31, 2015, the Company has accounted for its debt issuance cost2018.
Borrowings
The borrowings at acquisition typically require a fair market valuation performed as a reduction of the debt liability.

In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. This ASU eliminates from U.S. GAAP the concept of extraordinary items. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. Management has determined that this ASU had no impact to the Company as of December 31, 2015.

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

Management also considers the Company's capital adequacy, interest-rate risk, liquidity and business plans in assessing whether it is more likely than not that the Company will sell or be required to sell the investment securities before recovery. If the Company determines that a decline in fair value is OTTI and that it is more likely than not that the Company will not sell or be required to sell the investment security before recovery of its amortized cost, the credit portion of the impairment loss is recognized in the Company's consolidated statement of income and the noncredit portion is recognized in accumulated other comprehensive income. The credit portion of the OTTI impairment represents the difference between the amortized cost and the present value of the expected future cash flows of the investment security. If the Company determines that a decline in fair value is OTTI and it is more likely than not that it will sell or be required to sell the investment security before recovery of its amortized cost, the entire difference between the amortized cost and the fair value of the security will be recognized in the Company's consolidated statement of income.
Investment Securities Available-For-Sale Impairment Analysis
The following discussion summarizes, by investment security type, the basis for evaluating if the applicable investment securities within the Company’s available-for-sale portfolio were OTTI as of December 31, 2015.2018. Based on the analysis below and the determination that, it is more likely than not that the Company will not sell or be required to sell the investment securities before recovery of its amortized cost. The Company's ability and intent to hold these investment securities until recovery is supported by the Company's strong capital and liquidity positions as well as its historically low portfolio turnover. As such, Managementmanagement has determined that the investment securities are not OTTI as of December 31, 2015.2018. If market

The net unamortized deferred loan origination fees and costs included in total loans and leases were $12.8$15.6 million and $15.0$15.5 million as of December 31, 20152018 and 2014,2017, respectively.
The Company's Banks and subsidiaries lend primarily in eastern Massachusetts, southern New Hampshire and Rhode Island, with the exception of equipment financing, 32.8%26.8% of which is in the greater New York and New Jersey metropolitan area and 67.2%73.2% of which is in other areas in the United States of America as of December 31, 2015,2018, as compared to 35.9%28.0% of which is in the greater New York and New Jersey metropolitan area and 64.1%72.0% of which is in other areas in the United States of America as of December 31, 2014.2017.
Competition for indirect automobile loans increased significantly in recent years as credit unions and large national banks entered indirect automobile lending. That competition drove interest rates down and, in some cases, changed the manner in which interest rates are developed, from including a dealer-shared spread to imposing a dealer-based fee to originate the loan. Given this market condition, Management ceased the Company's origination of indirect automobile loans in December 2014. For the quarter ended March 31, 2015, the Company sold over 90% of the portfolio for $255.2 million, which resulted in a loss of $11.8 thousand excluding the impact on the allowance for loan and lease losses. Refer to Note 7, "Allowance for Loan and Lease Losses" for the impact of the sale on the Company's allowance for loan and lease losses.

On a quarterly basis, subsequent to acquisition, Managementmanagement reforecasts the expected cash flows for acquired ASC 310-30 loans, taking into account prepayment speeds, probability of default and loss given defaults. Management compares cash flow projections per the reforecast to the original cash flow projections and determines whether any reduction in cash flow expectations are due to deterioration, or if the change in cash flow expectation is related to noncredit events. This cash flow analysis is used to evaluate the need for a provision for loan and lease losses and/or prospective yield adjustments. During the years ended December 31, 2015, 20142018, 2017 and 2013,2016, accretable yield adjustments totaling $4.5$1.5 million, $2.1$4.0 million, and $8.5 $0.3

The aggregate remaining nonaccretable difference applicable to acquired loans and leases totaled $2.9 million and $3.6 million as of December 31, 2015 and 2014, 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 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 the applicable 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 as of December 31, 2015.2018.

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

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

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

loans subsequent to acquisition. The qualitative factors used in the determination are the same as those used for originated loans.

During the third quarter of 2015, the Company enhanced and refined its general allowance methodology to provide further quantification of probable losses in the portfolio. Under the enhanced methodology, Managementmanagement combined the historical loss histories of the Banks to generate a single set of ratios. Management believes it is appropriate to aggregate the ratios as the Banks share common environmental factors, operate in similar geographic markets, and utilize common underwriting standards in accordance with the Company's Credit Policy. In prior periods to the three months ended September 30, 2015, a historical loss history applicable to each Bank was used.

Management employed a similar analysis for the consolidation of the qualitative factors as it did for the quantitative factors. Again, Managementmanagement believes the realignment of the existing nine qualitative factors used at each of the Banks into a single group of factors for use across the Company is appropriate based on the commonality of environmental factors, markets and underwriting standards among the Banks. In prior periods to the three months ended September 30, 2015, each of the Banks utilized a set of qualitative factors applicable to each Bank.

The Company’s December 31, 2015 allowance calculation included a further segmentation of the commercial loans and leases to reflect the increased risk in the Company’s taxi medallion portfolio. As of December 31, 2015, this portfolio is approximately $35.8 million. Based on industry conditions, Management established a specific loss factor for this portfolio that best represents the changing risks associated with it.

Based on the refinements to the Company’s allowance methodology discussed above, Managementmanagement determined that the potential risks anticipated by the unallocated allowance are now incorporated into the allowance methodology, making the unallocated allowance unnecessary. In prior periods, the unallocated allowance was used to recognize the estimated risk associated with the allocated general and specific allowances. It incorporated Management’smanagement’s evaluation of existing conditions that were not included in the allocated allowance determinations and provided for losses that arise outside of the ordinary course of business.

Specific valuation allowances are established for impaired originated loans with book values greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent impaired loans, for any excess of a loan's book balance and the fair value of its underlying collateral. Specific valuation allowances are established for acquired loans with deterioration in the discounted present value of expected future cash flows since acquisitions or, in the case of collateral dependent impaired loans, for any increase in the excess of a loan's book balance greater than the fair value of its underlying collateral. A specific valuation allowance for losses on TDR loans is initially determined by comparing the net carrying amount of the troubled debt restructured loan with the restructured loan's cash flows discounted at the original effective rate. Impaired loans are reviewed quarterly with adjustments made to the calculated reserve as necessary.

As of December 31, 2015, Management2018, management believes that the methodology for calculating the allowance is sound and that the allowance provides a reasonable basis for determining and reporting on probable losses in the Company’s loan portfolios.

As of December 31, 2018, the Company had a portfolio of approximately $13.7 million in loans secured by taxi medallions issued by the cities of Boston and Cambridge. As of December 31, 2017, this portfolio was approximately $19.7 million. Application-based mobile ride services, such as Uber and Lyft, have generated increased competition in the transportation sector, resulting in a reduction in taxi utilization and, as a result, a reduction in the collateral value and credit quality of taxi medallion loans. This has increased the likelihood that loans secured by taxi medallions may default, or that the borrowers may be unable to repay these loans at maturity, resulting in an increase in past due loans, troubled debt restructurings, and charge-offs. Therefore, beginning with the three months ended September 30, 2015, the Company’s allowance calculation included an enhanced segmentation of the commercial loans and leases to reflect the increased risk in the Company’s taxi medallion portfolio. This allowance calculation segmentation represents management’s estimations of the special risks associated with the taxi portfolio.

As of December 31, 2018, the Company had an allowance for loan and lease losses associated with taxi medallion loans of
$2.5 million of which $1.9 million were specific reserves and $0.6 million was a general reserve. As of December 31, 2017, the Company had a reserve for loan and lease losses associated with taxi medallion loans of $3.8 million of which $2.7 million were specific reserves and $1.1 million was a general reserve. The decrease in the allowance for loans associated with taxi medallion loans was primarily driven by the decrease in specific reserves due to the charge-offs to the portfolio. The total troubled debt restructured loans secured by taxi medallions remained consistent at $3.7 million at December 31, 2018 and 2017. The total loans secured by taxi medallions that were placed on nonaccrual decreased to $3.7 million at December 31, 2018 from $7.8 million at December 31, 2017. The decrease in total loans secured by taxi medallions was primarily driven by the charge-offs of $3.8 million and the pay down in taxi medallion loans. Further declines in demand for taxi services or further deterioration in the value of taxi medallions may result in higher delinquencies and losses beyond that provided for in the allowance for loan and lease losses.

The general allowance for loan and lease losses was $53.1$55.6 million as of December 31, 2015,2018, compared to $50.1$55.5 million as of December 31, 2014.2017. The general portion of the allowance for loan and lease losses increased by $3.0$0.1 million during the year ended December 31, 2015,2018, as a result of the continued growth in the commercial real estate and commercial and industrialCompany's loan portfolios, partiallypartly offset by the decrease in historical loss factors applied to the indirect auto portfolios, which resulted in a release of $1.9 million in the general allowance forcommercial loan and lease losses in the first quarter of 2015.portfolio.

The specific allowance for loan and lease losses was $3.6remained consistent at $3.1 million as of December 31, 2015, compared to $1.2 million as of December 31, 2014. The specific allowance increased by $2.5 million during the year ended December 31, 2015, primarily due to one commercial relationship which was downgraded during the year ended December 31, 2015.2018 and 2017.

The changes to the methodology described above resulted in a reallocation of reserve from unallocated to specific loan segments. As such, the reserve for unallocated allowance for loan and lease losses as of December 31, 2015 was reduced to zero, compared to $2.4 million as of December 31, 2014.

Credit Quality Assessment

December 31, 2015, 2014, 2013

At the time of loan origination, a rating is assigned based on the capacity to pay and general financial strength of the borrower, the value of assets pledged as collateral, and the evaluation of third party support such as a guarantor. The Company continuallyperiodically monitors the quality of the loan portfolio using all available information. The officer responsible for handling each loan is required to initiate changes to risk ratings when changes in facts and circumstances occur that warrant an upgrade or downgrade in a loan rating. Based on this information, loans demonstrating certain payment issues or other weaknesses may be categorized as delinquent, impaired, nonperforming and/or put on nonaccrual status. Additionally, in the course of resolving such loans, the Company may choose to restructure the contractual terms of certain loans to match the borrower's ability to repay the loan based on their current financial condition. If a restructured loan meets certain criteria, it may be categorized as a troubled debt restructuring.
The Company reviews numerous credit quality indicators when assessing the risk in its loan portfolio. For all loans, the Company utilizes an eight-grade loan rating system, which assigns a risk rating to each borrower based on a number of quantitative and qualitative factors associated with a loan transaction. Factors considered include industry and market conditions; position within the industry; earnings trends; operating cash flow; asset/liability values; debt capacity; guarantor strength; management and controls; financial reporting; collateral; and other considerations. In addition, the Company's independent loan review group evaluates the credit quality and related risk ratings in all loan portfolios. The results of these reviews are reported to the Risk Committee of the Board of Directors on a periodic basis and annually to the Board of Directors. For the consumer loans, the Company heavily relies on payment status for calibrating credit risk.

F-38

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

The ratings categories used for assessing credit risk in the commercial real estate, multi-family mortgage, construction, commercial, equipment financing, condominium association and other consumer loan and lease classes are defined as follows:
1 -4 Rating—Pass
Loan rating grades "1" through "4" are classified as "Pass," which indicates borrowers are performing in accordance with the terms of the loan and are less likely to result in loss due to the capacity of the borrower to pay and the adequacy of the value of assets pledged as collateral.
5 Rating—Other Assets Especially Mentioned ("OAEM")
Borrowers exhibit potential credit weaknesses or downward trends deserving Management'smanagement's attention. If not checked or corrected, these trends will weaken the Company's asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned.
6 Rating—Substandard
Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt. Substandard loans may be inadequately protected by the current net worth and paying capacity of the obligors or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy. Although no loss of principal is envisioned, there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Collateral coverage may be inadequate to cover the principal obligation.
7 Rating—Doubtful
Borrowers exhibit well-defined weaknesses that jeopardize the orderly liquidation of debt with the added provision that the weaknesses make collection of the debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely.
8 Rating—Definite Loss
Borrowers deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuation as active assets of the Company is not warranted.
Assets rated as "OAEM," "substandard" or "doubtful" based on criteria established under banking regulations are collectively referred to as "criticized" assets.

Commercial Real Estate Loans—As of December 31, 2015,2018, loans outstanding in the three classes within this segment expressed as a percentage of total loans and leases outstanding were as follows: commercial real estate loans -- 37.5%(37.0%); multi-family mortgage loans -- 13.2%(13.4%); and construction loans -- 2.6%(2.7%).
Loans in this portfolio that are on nonaccrual status and/or risk-rated "substandard" or worse are evaluated on an individual loan basis for impairment. For non-impaired commercial real estate loans, loss factors are applied to outstanding loans by risk rating for each of the three classes in the portfolio. The factors applied are based primarily on historic loan loss experience and an assessment of internal and external factors and other relevant information.
Commercial Loans and Leases—As of December 31, 2015,2018, loans and leases outstanding in the three classes within this segment expressed as a percent of total loans and leases outstanding were as follows: commercial loans and leases -- 11.9%(11.7%); equipment financing loans -- 14.5%(15.6%); and loans to condominium associations -- 1.2%(0.8%).
Loans and leases in this portfolio that are on nonaccrual status and/or risk-rated "substandard" or worse are evaluated on an individual basis for impairment. For non-impaired commercial loans and leases, loss factors are applied to outstanding loans by risk rating for each of the three classes in the portfolio.
Consumer Loans—As of December 31, 2015,2018, loans outstanding within the fourthree classes within this segment expressed as a percent of total loans and leases outstanding were as follows: residential mortgage loans -- 12.3%(12.4%), home equity loans -- 6.3%, indirect automobile loans -- 0.3%(6.0%), and other consumer loans -- 0.2%(0.4%).
Significant risk characteristics related to the residential mortgage and home equity loan portfolios are the geographic concentration of the properties financed within selected communities in the greater Boston and Providence metropolitan areas.

The payment status and loan-to-value ratio are the primary credit quality indicator used for residential mortgage loans and home equity loans. Generally, loans are not made when the loan-to-value ratio exceeds 80% unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Consumer loans that become 90 days or more past due, or are placed on nonaccrual regardless of past due status, are reviewed on an individual basis for impairment by assessing the net realizable value of underlying collateral and the economic condition of the borrower. Determination of the allowance for loan and lease losses for indirect automobile loans is based primarily on payment status and historical loss rates.
Impaired Loans and Leases
A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. The Company has defined the population of impaired loans to include nonaccrual loans and troubled debt restructured loans.
When the ultimate collectability of the total principal of an impaired loan or lease is in doubt and the loan is on nonaccrual status, all payments are applied to principal, under the cost recovery method. When the ultimate collectability of the total principal of an impaired loan or lease is not in doubt and the loan or lease is on nonaccrual status, contractual interest is credited to interest income when received, under the cash basis method.
The following tables include the recorded investment and unpaid principal balances of impaired loans and leases with the related allowance amount, if applicable, for the originated and acquired loan and lease portfolios at the dates indicated. Also presented are the average recorded investments in the impaired loans and leases and the related amount of interest recognized during the period that the impaired loans were impaired.

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

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'smanagement's credit evaluation of the borrower.

Standby and commercial letters of credits are conditional commitments issued by the Company to guarantee performance of a customer to a third party. These standby and commercial letters of credit are primarily issued to support the financing needs of the Company's commercial customers. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.
The liability for unfunded credit commitments, which is included in other liabilities, was $1.3$1.9 million and $1.7 million as of December 31, 20152018 and December 31, 2014,2017, respectively.
From time to time, the Company enters into back-to-back interest rate swapsloan level derivatives, risk participation agreements or foreign exchange contracts with commercial customers and third-party financial institutions. These swapsderivatives allow the Company to offer long-term fixed-rate commercial loans while mitigating the interest-rate or foreign exchange risk of holding those loans. In a back-to-back interest rate swaploan level derivative transaction, the Company lends to a commercial customer on a floating-rate basis and then enters into an interest rate swaploan level derivative with that customer. Concurrently, the Company enters into offsetting swaps with a third-party financial institution, effectively minimizing its net interest-rate risk exposure resulting from such transactions.
The fair value of interest rate swapderivative assets and liabilities was $8.7$22.5 million and $8.8$22.2 million, respectively, as of December 31, 2015.2018. The fair value of interest rate swapderivative assets and liabilities was $2.7$9.0 million and $2.7$8.9 million, respectively, as of December 31, 2014.2017.
The fair value of foreign exchange assets and liabilities was $131 thousand and $123 thousand, respectively, as of December 31, 2018. The fair value of foreign exchange assets and liabilities was $72 thousand and $65 thousand as of December 31, 2017.

(16) Derivatives and Hedging Activities
The Company may useutilizes loan level derivatives which consist of interest-rate contracts (swaps, caps and floors), and risk participation agreements as part of the Company's interest-rate risk management strategy. strategy for certain assets and liabilities and not for speculative purposes. Based on the Company's intended use for the loan level derivatives at inception, the Company designates the derivative as either an economic hedge of an asset or liability, or a hedging instrument subject to the hedge accounting provisions of FASB ASC Topic 815, "Derivatives and Hedging".
Interest-rate swap, cap and floor agreements are entered into as hedges against future interest-rate fluctuations on specifically identified assets or liabilities. The Company did not have derivative fair value hedges or derivative cash flow hedges as of December 31, 2015 and 2014.2018 or 2017.
Derivatives not designated as hedges are not speculative, but rather, result from a service the Company provides to certain customers for a fee. The Company executes loan level derivative products such as interest-rate swapsswap agreements with commercial banking customers to aid them in managing their interest-rate risk. The interest-rate swap contracts allow the commercial banking customers to convert floating-rate loan payments to fixed-rate loan payments. The Company concurrently enters into offsetting swaps with a third-partythird 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 swapsswap agreements 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 64 interest-rate swapsutilizes risk participation agreements with an aggregate notional amountother banks participating in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. Risk participation agreements are derivative financial instruments and are recorded at fair value. These derivatives are not designated as hedges and therefore, changes in fair value are recorded directly through earnings at each reporting period. The risk participation-out agreements have grown in tandem with the Company's increase in derivative activity.
Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of $490.6 millionthe credit risk associated with the interest rate swap position executed with the commercial borrower, for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Company assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower, for a fee received from the other bank.
The Company offers foreign exchange contracts to commercial borrowers to accommodate their business needs. These foreign exchange contracts do not qualify as hedges for accounting purposes. To mitigate the market and 22 interest-rate swapsliquidity risk associated with an aggregate notional amount of $109.4 million related to this program as of December 31, 2015 and 2014, respectively.these foreign exchange contracts, the Company enters into similar offsetting positions.
Asset derivatives and liability derivatives are included in other assets and accrued expenses and other liabilities on the
consolidated balance sheets, respectively. sheets.

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 Managementmanagement believes to be creditworthy and by limiting the amount of exposure to each counterparty by either cross collateralizing the underlying hedged loan or through bilateral posting of collateral to cover exposure. As the swaps are subject to master netting agreements, the Company had limited exposure relating to interest rate swapsloan level derivatives with institutional counterparties as of December 31, 20152018 and 2014.2017. The estimated net credit risk exposure for derivative financial instruments was $125.0 thousand and $38.0 thousandzero as of December 31, 2015,2018, and 2014, respectively.2017.
Certain derivative agreements contain provisions that require the Company to post collateral if the derivative exposure exceeds a threshold amount. The Company posted collateral of $14.7$5.9 million and $5.4$26.7 million in the normal course of business as of December 31, 20152018 and 2014,2017, respectively.

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

The Company's effective tax rate was 23.2% as of December 31, 2015, 2014, 20132018 compared to 44.9% as of December 31, 2017. The decrease in the Company's effective tax rate from 2017 was primarily driven by the expected income tax expense, which was $10.4 million lower in 2018, as a result of the Tax Reform Act. Also, there was a $9.0 million Tax Reform Adjustment in 2017, the year of enactment. In 2018, the Company made an adjustment related to the Tax Reform Act that reduced the provision for income taxes by $0.7 million.
On December 22, 2017, the Tax Reform Act was enacted, which represents the most comprehensive reform to the U.S. tax code in over thirty years. The majority of the provisions of the Tax Reform Act took effect on January 1, 2018. The Tax Reform Act lowers the Company’s federal tax rate from 35% to 21%. The Tax Reform Act also contains other provisions that may affect the Company currently or in future years. Among these are changes to the deductibility of meals and entertainment, the deductibility of executive compensation, accelerated expensing of depreciable property for assets placed in service after September 27, 2017 and before 2023, limits the deductibility of net interest expense, eliminated the corporate alternative minimum tax, limited net operating loss carryforwards to 80% of taxable income and other provisions. Recent changes in 2018 also include a parking disallowance in regards to employee parking, which the Company has taken into account in calculating the effective tax rate.
As a result of the Tax Reform Act, in 2017, management re-valued the carrying value of our net deferred tax asset and investments in low income housing tax credits. The impact of the Tax Reform Act resulted in a write down of the carrying balance of net deferred tax assets and investments in affordable housing projects of $8.6 million and $0.3 million, respectively.

As of December 31, 2015,2018, the Company had net operating loss carryforwards for federal income tax purposes of $3.7$4.6 million gross which are available to offset future federal taxable income, if any, through 2020. In addition, the Company has alternative minimum tax credit carryforwards of $31.0 thousand, which are available to reduce future federal income taxes, if any, over an indefinite period. According to Section 382 of the Internal Revenue Code, theOf this total net operating loss carryforwards and credit are subjectcarryforward amount, $3.5 million is related to an annual limitation of $0.9 million.the Company's First Commons Bank transaction.
The Company has determined that a valuation allowance is not required for any of its deferred tax assets because it believes that it is more likely than not that these assets will reverse against future taxable income.
For federal income tax purposes, the Company has a $1.8 million reserve for credit losses which remains subject to recapture. If any portion of the reserve is used for purposes other than to absorb the losses for which it was established, approximately 150% of the amount actually used (limited to the amount of the reserve) would be subject to taxation in the year in which used. As the Company intends to use the reserve only to absorb credit losses, no provision has been made for the $1.0$0.5 million liability that would result if 100% of the reserve were recaptured.
The Company did not have any unrecognized tax benefits accrued as income tax payables, receivables or as deferred tax items as of December 31, 20152018 and 2014.

Capital Distributions and Restrictions Thereon
The Company is a legal entity separate and distinct from each of the Banks and Brookline Securities Corp. The Company's primary source of revenue is dividends paid to it by the Banks and Brookline Securities Corp.
The FRB has authority to prohibit the Company from paying dividends to the Company's shareholders if such payment is deemed to be an unsafe or unsound practice. The FRB has indicated generally that it may be an unsafe or unsound practice for bank holding companies to pay dividends unless the bank holding company's net income over the preceding year is sufficient to fund the dividends and the expected rate of earnings retention is consistent with the organization's capital needs, asset quality and overall financial condition.
The FRB also has the authority to use its enforcement powers to prohibit the Banks from paying dividends to the Company if, in its opinion, the payment of dividends would constitute an unsafe or unsound practice. Federal law also prohibits the payment of dividends by a bank that will result in the bank failing to meet its applicable capital requirements on a pro forma basis. In addition, a state bank that is a member of the Federal Reserve System may not declare or pay a dividend if the total of all dividends declared during the calendar year, including the proposed dividend, exceeds the sum of the bank's net income (as reportable in its Reports of Condition and Income) during the current calendar year and the retained net income of the prior two calendar years, unless the dividend has been approved by the FRB. Payment of dividends by a bank is also restricted pursuant to various state regulatory limitations, including the Massachusetts Division of Banks in the case of Brookline Bank and First Ipswich, and the Banking Division of the Rhode Island Department of Business Regulation in the case of BankRI.
Common Stock Repurchases
In 2015, 2014 and 2013, no shares of the Company's common stock were repurchased by the Company.

Common Stock Issuance
On March 1, 2018, the Company completed the acquisition of First Commons Bank. First Commons Bank was merged with and into the Company’s subsidiary bank, Brookline Bank. The Transaction qualified as a tax-free reorganization for federal income tax purposes. The total Transaction consideration was $56.0 million. First Commons Bank stockholders received, for each share of First Commons Bank common stock, the right to receive 1.089 shares of the Company’s common stock with cash in lieu of fractional shares, options, and warrants, resulting in a total cash consideration payment of $851 thousand and an increase to the Company’s outstanding shares of 3,481,477 shares.
On, April 27, 2017, the Company entered into an underwriting agreement with Piper Jaffray & Co., as representative of the underwriters named therein (collectively, the “Underwriters”), to offer and sell 5,175,000 shares of the Company’s common stock, $0.01 par value per share at a public offering price of $14.50 per share in an underwritten public offering (the “Offering”).

On May 2, 2017, the Company and the Underwriters closed the Offering. The Underwriters exercised their option resulting in a new issuance in the aggregate of 5,951,250 shares of the Company’s common stock at a price to the public of $14.50 per share.

Restricted Retained Earnings
As part of the stock offering in 2002 and as required by regulation, Brookline Bank established a liquidation account for the benefit of eligible account holders and supplemental eligible account holders who maintain their deposit accounts at Brookline Bank after the stock offering. In the unlikely event of a complete liquidation of Brookline Bank (and only in that event), eligible depositors who continue to maintain deposit accounts at Brookline Bank shall be entitled to receive a distribution from the liquidation account.
Accordingly, retained earnings of the Company are deemed to be restricted up to the balance of the liquidation account. The liquidation account balance is reduced annually to the extent that eligible depositors have reduced their qualifying deposits as of each anniversary date. Subsequent increases in deposit account balances do not restore an account holder's interest in the liquidation accountaccount.
The liquidation account totaled $16.6$13.0 million (unaudited), $18.4$15.1 million (unaudited), and $20.6$15.2 million (unaudited) at

(19) Regulatory Capital Requirements

December 31, 2015, 2014, 2013

The Company's primary source of cash is dividends from the Banks and Brookline Securities Corp. The Banks are subject to certain restrictions on the amount of dividends that they may declare without prior regulatory approval. In addition, the dividends declared cannot be in excess of the amount which would cause the Banks to fall below the minimum required for capital adequacy purposes.
The Company is a bank holding company within the meaning of the Bank Holding Company Act of 1956, as amended (the "BHCA") and as such, must comply with the capital requirements of the Federal Reserve Bank (the "FRB")FRB at the consolidated level. As member banks of the FRB, Brookline Bank, BankRI and First Ipswich are also required to comply with the regulatory capital requirement of the FRB.
The FRB has promulgated regulations imposing minimum capital requirements for bank holding companies and state member banks as well as prompt corrective action regulations for state member banks that implement the system of prompt corrective action established by Section 38 of the Federal Deposit Insurance Act, as amended (the "FDIA"). Under the prompt corrective action regulations in effect as of December 31, 2015,2018, a bank is "well-capitalized" if it has: (1) a total risk-based capital ratio of 10.0% or greater; (2) a Tier 1 risk-based capital ratio of 8.0% or greater; (3) a common equity Tier 1 capital ratio of 6.5% or greater; (4) a Tier 1 leverage ratio of 5.0% or greater; and (5) is not subject to any written agreement, order, capital directive or prompt corrective action directive to meet and maintain a specific capital level for any capital measure.
Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines, the Company and each of the Banks must meet specific capital guidelines that involve quantitative measures of the Company's and the Banks' assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. In addition, the prompt corrective action rules applicable to state member banks establish a framework of supervisory actions for state member banks that are not at least adequately capitalized. The Company's and the Banks' capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. Bank holding companies are not subject to prompt corrective action requirements. However, a bank holding company is considered "well capitalized" for purpose of the FRB's Regulation Y (which can affect eligibility for expedited application processes to make acquisitions and engage in new activities) if the bank holding company maintains on a consolidated basis a total risk-based capital ratio of 10.0% or greater and a Tier 1 risk-based capital ratio of 6.0% or greater and is not subject to any written agreement under capital directive or prompt correction action directive issued by the FRB to meet and maintain a specific capital level for any capital measure.
AsBeginning January 1, 2019, the Company and the Banks will have to maintain a capital conservation buffer composed of CET1 capital equal to 2.5% of risk-weighted assets above the amounts required to be adequately capitalized in order to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. Capital ratios required to be considered well-capitalized exceed the ratios required under the capital conservation buffer requirement at December 31, 2015, the Company, Brookline Bank, BankRI and First Ipswich met all applicable minimum capital requirements and the banks were considered "well-capitalized" by their respective regulators. The Company's and the Banks' actual and required capital amounts and ratios are as follows:2018.

As of December 31, 2015, 2014, 20132018, the Company and the Banks are each under the primary regulation of, and must comply with, the capital requirements of the FRB. As of December 31, 2018, the Company and the Banks exceeded all regulatory capital requirements and were considered “well-capitalized” under prompt corrective action regulations, as amended to reflect the changes under Basel III Capital Rules. The following table presents actual and required capital ratios as of December 31, 2018 for the Company and the Banks under the Basel III Capital Rules based on the phase-in provision of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased in.

Brookline Bank established an Employee Stock Ownership Plan ("ESOP") on November 1, 1997. The Company's ESOP loan to Brookline Bank to purchase 546,986 shares of Company common stock is payable in quarterly installments over 30 years, bears interest at 8.50% per annum, matures December 31, 2021, and can be prepaid without penalty. The loan is repaid to the Company in the form of cash contributions from Brookline Bank, subject to federal tax law limits. The outstanding balance of the loan as of December 31, 20152018 and 2014,2017, was $1.8$1.0 million and $2.0$1.3 million,, respectively, and is eliminated in consolidation.
Shares of common stock used as collateral to secure the loan are released and available for allocation to eligible employees as the principal and interest on the loan is paid. The ESOP was amended in 2015 to permit all eligible participants in the ESOP as of July 1, 2015 or any eligible participants after July 1, 2015 to be fully vested in the ESOP upon the date of eligibility.
Dividends on released shares are credited to the participants' ESOP accounts. Dividends on unallocated shares of common stock are generally applied towards payment of the loan. ESOP shares committed to be released are considered outstanding in determining earnings per share.
As of December 31, 20152018 and 2014,2017, the ESOP held 213,066109,950 and 251,382142,332 unallocated shares, respectively at an aggregate cost of $1.1$0.6 million and $1.3$0.7 million, respectively.

Of the awarded shares, generally 50% vest ratably over three years with one-third of such shares vesting at each of the first, second and third anniversary dates of the awards. These are referred to as "time-based shares". The remaining 50% of each award has a cliff vesting schedule and will vest three years after the award date based on the level of the Company's achievement of identified performance targets in comparison to the level of achievement of such identified performance targets by a defined peer group comprised of 17 financial institutions. These are referred to as "performance-based shares". The specific performance measure targets relate to return on assets, return on tangible equity, asset quality and total stockholder return (share price appreciation from date of award plus dividends paid as a percent of the Company's common stock share price on the date of award). If a participant leaves the Company prior to the third anniversary date of an award, any unvested shares are forfeited. Dividends declared with respect to shares awarded will be held by the Company and paid to the participant only when the shares vest.
Under all the Plans, shares of the Company's common stock were reserved for issuance as restricted stock awards to officers, employees, consultants and non-employee directors of the Company. Shares issued upon vesting may be either authorized but unissued shares or reacquired shares held by the Company as treasury shares. Any shares not issued because vesting requirements are not met will be retired back to treasury and be made available again for issuance under the Plans.
Total expense for the Plans was $1.4$2.5 million in 2015, $1.22018, $2.3 million in 20142017 and 2013,$1.8 million in 2016, respectively.

Stock Option Plans
The Company has an active equity incentive plan, the 2014 Plan. The prior plans, the "2003 Option Plan" and the "1999 Option Plan" were terminated on October 16, 2013 and April 19, 2009, respectively. The 2014 plan is an omnibus plan from which the Company may award up to 1,750,000 shares of restricted stock or stock options among other types of awards. Under all the stock option plans, shares of the Company's common stock were reserved for issuance to directors, employees, consultants and non-employee directors of the Company. Shares issued upon the exercise of a stock option may be either authorized but unissued shares or reacquired shares held by the Company as treasury shares. Any shares subject to an award which expire or are terminated unexercised will again be available for issuance under the plans.
The exercise price of options awarded is the fair market value of the common stock of the Company on the date the award is made. Certain of the options include a reload feature whereby an optionee exercising an option by delivery of shares of common stock would automatically be granted an additional option at the fair market value of stock when such additional option is granted equal to the number of shares so delivered. If an individual to whom a stock option was granted ceases to maintain continuous service by reason of normal retirement, death or disability, or following a change in control, all options and rights granted and not fully exercisable become exercisable in full upon the happening of such an event and shall remain exercisable for a period ranging from 3 months to 5 years.

Investment Securities Available-for-Sale
The fair value of investment securities is based principally on market prices and dealer quotes received from third-party and nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's marketableDuring the 3rd quarter of 2018, the Company re-designated all equity securities are priced this wayas held-for-trading and are included in Level 1.levels 1 and 2. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include GSE debentures, GSE mortgage-related securities, SBA commercial loan asset backed securities, corporate debt securities, and trust preferred securities, all of which are included in Level 2. As of December 31, 20152018 and December 31, 2014,2017, no investment securities were valued using pricing models included in Level 3.
Additionally, Managementmanagement 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'smanagement's expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for a particular security.

Loan Level Derivatives
The fair values for the interest-rate swap assets and liabilities represent a Level 2 valuation and are based on settlement values adjusted for credit risks associated with the counterparties and the Company and observable market interest rate curves. Credit risk adjustments consider factors such as the likelihood of default by the Company and its counterparties, its net exposures and remaining contractual life. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position. Refer also to Note 16, "Derivatives and Hedging Activities."

These investments include GSE debentures, GSE MBSs, and municipal obligations, all of which are included in Level 2. Additionally, fair values of foreign government obligations are based on comparisons to market prices of similar securities and are considered to be Level 3.
Loans Held-for-Sale
Fair value is measured using quoted market prices when available. These assets are typically categorized as Level 1. If quoted market prices are not available, comparable market values may be utilized. These assets are typically categorized as Level 2.

Loans and Leases
The fair values of performing loans and leases was estimated by segregating the portfolio into its primary loan and lease categories—commercial real estate mortgage, multi-family mortgage, construction, commercial, equipment financing, condominium association, indirect automobile, residential mortgage, home equity and other consumer. These categories were further disaggregated based upon significant financial characteristics such as type of interest rate (fixed / variable) and payment status (current / past-due). The Company discounts the contractual cash flows for each loan category using interest rates currently being offered for loans with similar terms to borrowers of similar quality and incorporates estimates of future loan prepayments.

December 31, 2015, 2014, 2013

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.

(24) Revenue from Contracts with Customers
Overview
Revenue from contracts with customers in the scope of Accounting Standards Codification (“ASC”) ("Topic 606") is measured based on the consideration specified in the contract with a customer and excludes amounts collected on behalf of third parties. The Company recognizes revenue from contracts with customers when it satisfies its performance obligations.
The Company’s performance obligations are generally satisfied as services are rendered and can either be satisfied at a point in time or over time. Unsatisfied performance obligations at the report date are not material to our consolidated financial statements.
In certain cases, other parties are involved with providing services to our customers. If the Company is a principal in the transaction (providing services itself or through a third party on its behalf), revenues are reported based on the gross consideration received from the customer and any related expenses are reported gross in noninterest expense. If the Company is an agent in the transaction (referring to another party to provide services), the Company reports its net fee or commission retained as revenue.

BROOKLINE BANCORP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements (Continued)

Accounting Policy Updates
The Company adopted Topic 606, “Revenue from Contracts with Customers” effective January 1, 2018 and has applied the guidance to all contracts within the scope of Topic 606 as of that date. As a result, the Company has modified its accounting policy for revenue recognition as detailed in this Note.
As discussed in Note 1, the Company applied Topic 606 using the modified retrospective method, therefore, the prior period comparative information has not been adjusted and continues to be reported under Topic 605. There was no cumulative effect adjustment as of January 1, 2018, and there were no material changes to our consolidated financial statements at or for the twelve months ended December 31, 2018, as a result of adopting Topic 606.
The Company applied the practical expedient pertaining to contracts with original expected duration of one year or less and does not disclose information about remaining performance obligations on such contracts.
The Company also applied the practical expedient pertaining to contracts for which, at contract inception, the period between when the entity transfers the services and when the customer pays for those services will be one year or less. As such, the Company does not adjust the consideration from customers for the effects of a significant financing component.
A substantial portion of the Company’s revenue is specifically excluded from the scope of Topic 606. This exclusion is associated with financial instruments, including interest income on loans and investment securities, in addition to loan derivative income and gains on loan and investment sales. For the revenue that is in-scope of Topic 606, the following is a description of principal activities from which the Company generates its revenue from contracts with customers, separated by the timing of revenue recognition.
Revenue Recognized at a Point in Time
The Company recognizes revenue that is transactional in nature and such revenue is earned at a point in time. Revenue that is recognized at a point in time includes card interchange fees (fee income related to debit card transactions), ATM fees, wire transfer fees, overdraft charge fees, and stop-payment and returned check fees. Additionally, revenue is collected from loan fees, such as letters of credit, line renewal fees and application fees. Such revenue is derived from transactional information and is recognized as revenue immediately as the transactions occur or upon providing the service to complete the customer’s transaction.
Revenue Recognized Over Time
The Company recognizes revenue over a period of time, generally monthly, as services are performed and performance obligations are satisfied. Such revenue includes commissions on investments, insurance sales and service charges on deposit accounts. Fee revenue from service charges on deposit accounts represent the service charges assessed to customers who hold deposit accounts at the Bank.
(25) Subsequent Events
Eastern Funding, LLC Acquisition
As of December 31, 2018, Brookline Bank, a wholly-owned subsidiary of the Company, held an 84.07 percent ownership interest in its subsidiary, Eastern Funding. As previously announced, on January 4, 2019, Brookline Bank completed the purchase of the remaining 15.93 percent interest in Eastern Funding for a total cash consideration of $35.9 million
On January 30, 2019, the Board of Directors approved a stock repurchase program authorizing management to repurchase up to $10.0 million of the Company's common stock over a period of eleven months ending December 31, 2019.
The Company has evaluated subsequent events other than the matters described above and through the date of issuance.
