EXPLANATORY NOTE
As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on May 11, 2020, in accordance with the U.S. Security and Exchange Commission’s “Order under Section 36 of the Securities Exchange Act of 1934 Modifying Exemptions From the Reporting and Proxy Delivery Requirements for Public Companies” dated March 25, 2020 (Release No. 34-88465) (the “Order”), the Company relied on the relief provided by the Order to extend the filing of this Quarterly Report on Form 10-Q for the three months ended March 31, 2020 (the “Quarterly Report”). In compliance with public health orders related to the COVID-19 pandemic, the Company has transitioned to a remote working environment. The Company’s management has devoted significant time and attention to assessing the potential impact of the COVID-19 pandemic on the Company’s operations and financial position and developing operational and financial plans to address those matters, which has diverted management resources from completing tasks necessary to file this Quarterly Report by the original May 11, 2020 deadline.

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 and leases, the review of goodwill and intangiblesintangible assets for impairment and the review of deferred tax assets for valuation allowances.
 
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.

Recent Accounting Pronouncements
Accounting Standards Adopted in 2020
In May 2017,June 2016, the FASB issued ASU 2017-09, Compensation-Stock Compensation2016-13, “Financial Instruments - Credit Losses (Topic 718)326): ScopeMeasurement of Modification Accounting.Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 replaced the previous GAAP method of calculating credit losses. Previously, GAAP required the use of the incurred loss methodology, which used a higher threshold at which probable losses were calculated and recorded. ASU 2016-13 requires the use of an expected loss methodology, referred to as the current expected credit loss (“CECL”) methodology, which requires institutions to account for probable losses that previously would not have been part of the calculation. The CECL methodology incorporates future forecasting in addition to historical and current measures. The Company adopted all of the above mentioned ASU as of January 1, 2020. The standard had an impact on our consolidated balance sheet. On adoption, the Company recognized an increase in the allowance for loan and lease losses of $6.6 million, and an increase in the reserve for unfunded commitments of $8.9 million. The net, after-tax impact of the increase in the allowance for loan and lease losses and reserve for unfunded commitments was an decrease to retained earnings of $11.5 million shown in the Consolidated Statements of Changes in Stockholders’ Equity. Additional details can be found in Note 3, 4 and 5.
In August 2018, FASB issued this UpdateASU 2018-13, "Fair Value Measurement (Topic 820)" ("ASU 2018-13"), to addressmodify the diversity in practice as well as the cost and complexity when applying the guidancedisclosure requirements on fair value measurements in Topic 718, Compensation - Stock Compensation, to a change to820, Fair Value Measurement, based on the terms or conditionsconcepts set forth in the Concepts Statement, including the consideration of a share-based payment award. For public entities, thiscosts and benefits. This ASU is effective for annual reportingfiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Management has evaluated this2019. Certain provisions under ASU and has determined that ASU 2017-09 does apply. As of September 30, 2017,2018-13 required prospective application, while other provisions required retrospective application to all periods presented in the consolidated financial statements upon adoption. The Company has adopted the provisions of ASU 2018-13 effective January 1, 2020 and the adoption did not have a material impact on the Company’s consolidated financial statements.
In March 2017,
(2) Acquisitions and Mergers
First Ipswich Bank
On February 15, 2020, the FASB issued Accounting Standards Update ASU 2017-07, Improvingmerger of First Ipswich Bank with and into Brookline Bank was completed. First Ipswich was already a wholly-owned subsidiary of the Presentation of Net Periodic Pension CostCompany, therefore the merger qualified as a tax-free reorganization for federal income tax purposes and Net Periodic Postretirement Benefit Cost (Topic 715). This ASUthere 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 believes that this ASU applies and has determined theminimal impact to be immaterial ascustomers. All of September 30, 2017. Management will meetFirst Ipswich Bank's 6 branch locations were retained and converted to discuss and will put together a project team to assess steps to adoption prior to implementation of the standard in 2018.Brookline Bank branches.
In February 2017, the FASB issued ASU 2017-05, Other Income Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20). This ASU was issued to clarify the scope of Subtopic 610-20, and to add guidance for partial sales of nonfinancial assets. For public entities, this ASU is effective for annual reporting periods beginning after December 15, 2017. Management believes that this ASU applies and has determined the impact to be immaterial as of September 30, 2017.
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 has determined that ASU 2017-04 does apply. As of September 30, 2017, the Company has adopted the ASU and determined the impact to be immaterial.
In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). This ASU was issued to provide clarification and uniformity on the presentation and classification of certain cash receipts and cash payments in the statement of cash flows under Topic 230. The amendments presented in this ASU are effective for fiscal years beginning after December 15, 2017. As of September 30, 2017, management believes that ASU 2016-15 does apply, and after completing an internal analysis has determined the impact of adoption of this ASU in 2018 to the financial statement presentation 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

Adoption of Topic 326
Effective January 1, 2020, the Company adopted the provisions of ASU 2016-13 using the modified retrospective method. Therefore, prior period comparative information has not been adjusted and continues to be reported under GAAP in effect prior to the adoption of Topic 326. There was a de minimis allowance for the Nine Months Ended September 30, 2017 and 2016

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 tocredit loss ("ACL") on available-for-sale debt securities marked as other than temporarily impaired. A retrospective approach will be applied cumulatively to retained earnings. Earlyrecognized upon adoption is permittedand 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 September 30, 2017. In preparation for the adoption in 2019 of this ASU, management formed a steering committee which has developed an approach for implementationMarch 31, 2020.
The following tables set forth investment securities available-for-sale, held-to-maturity and has selected a third party software service provider.
In May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. The intention of this ASU is to provide additional clarification on specific issues brought forth by the FASB and the International Accounting Standards Board Joint Transition Resource Group for Revenue Recognition in relation to Topic 606 and revenue recognition. This ASU is to have the same effective date as ASU 2015-14 which deferred the effective date of ASU 2014-09 to December 15, 2017. Management has determined that ASU 2016-12 does apply as of September 30, 2017. Management assembled a project team to address the changes pursuant to Topic 606 and the majority of the work was performed on the contracts and management believes there will be no material impact. The standard will be effective on January 1, 2018.
In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This ASU was issued as part of the FASB Simplification Initiative which intends to reduce the complexity of GAAP while improving usefulness to users. The ASU was effective for annual periods beginning after December 15, 2016, and interim periods within those annual reporting periods with early adoption available. The Company adopted ASU 2016-09 effective January 1, 2017 and the adoption did not have a material impact on the Company’s consolidated financial statements.
In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This ASU was issued to clarify how to recognize revenue depending on an entities position, in relation to another entity involved, on contracts with customers. The entity can either be a principal party or an agent, and must record revenue accordingly. This ASU is not yet effective. Since this ASU affects ASU 2014-09, and that effective date was deferred, this ASU remains suspended too. Management has determined that this ASU does apply as of September 30, 2017. Management assembled a project team to address the changes pursuant to Topic 606 and the majority of the work was performed on the contracts. The project is substantially complete and Management believes that there is no material impact as a result of the adoption. The standard will be effective on January 1, 2018.
In February 2016, FASB issued ASU 2016-02, Leases. This ASU requires lessees to put most leases on their balance sheet but recognize expenses on their income statements in a manner similar to current accounting. This ASU also eliminates current real estate-specific provisions for all companies. For lessors, this ASU modifies the classification criteria and the accounting for sales-type and direct financing leases. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods therein. Early adoption is permitted. Management believes that this ASU applies and has not determined the impact, if any, as of September 30, 2017. Management has met to discuss the impact and will assemble a project team to assess steps required for adoption prior to implementation of the standard in 2019.

As a result of tainting of the held-to-maturity portfolio, the Company is precluded from classifying securities as held-to-maturity for a period of time.

Allowance for Credit Losses-Available-for-Sale Securities
For available-for-sale securities in an unrealized loss position, management first assesses whether (i) the Company intends to sell the security, or (ii) it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either criterion is met, any previously recognized allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither criterion is met, the security is evaluated to determine whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically related to the security, among other factors.
If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, an allowance for credit loss is recorded, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income. Adjustments to the allowance are reported as a component of credit loss expense. Available-for-sale securities are charged-off against the allowance or, in the absence of any allowance, written down through income when deemed uncollectible or when either of the aforementioned criteria regarding intent or requirement to sell is met. The Company has made the accounting policy election to exclude accrued interest receivable on available-for-sale securities from the estimate of credit losses. Accrued interest receivables associated with debt securities available-for-sale totaled $2.4 million and $2.0 million, respectively, as of March 31, 2020 and December 31, 2019.
A debt security is placed on nonaccrual status at the time any principal or interest payments become more than 90 days delinquent or if full collection of interest or principal becomes uncertain. Accrued interest for a debt security placed on nonaccrual is reversed against interest income. There were no debt securities on nonaccrual status and therefore there was no accrued interest related to debt securities reversed against interest income for the three months ended March 31, 2020 and 2019.

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

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

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 OTTIimpairment and that it is more likely than not that the Company will not sell or be required to sell the investment security before recovery of its amortized cost, the credit portion of the impairment loss is recognized in the Company's unaudited consolidated statement of income and the noncredit portion is recognized in accumulated other comprehensive income. The credit portion of the OTTI impairment represents the difference between the amortized cost and the present value of the expected future cash flows of the investment security. If the Company determines that a decline in fair value is OTTIimpairment and it is more likely than not that it will sell or be required to sell the investment security before recovery of its amortized cost, the entire difference between the amortized cost and the fair value of the security will be recognized in the Company's unaudited consolidated statement of income.
Investment Securities Available-For-Sale Impairment Analysis
The following discussion summarizes, by investment security type, the basis for evaluating if the applicable investment securities within the Company’s available-for-sale portfolio were OTTIimpaired as of September 30, 2017.March 31, 2020. Based on the analysis below, and the determinationit was determined that is it is more likely than not that the Company will not sell or be required to sell the investment securities before recovery of its amortized cost. The Company's ability and intent to hold these investment securities until recovery is supported by the Company's strong capital and liquidity positions as well as its historically low portfolio turnover. As such, management has determined that the investment securities are not OTTIimpaired as of September 30, 2017.March 31, 2020. If market

Accretable Yield for the Acquired Loan Portfolio
On a quarterly basis prior to the adoption of ASU 2016-13, management reforecasted the expected cash flows for acquired ASC 310-30 loans, and took into account prepayment speeds, probability of default and loss given defaults. Management compared cash flow projections per the reforecast to the original cash flow projections and determined whether any reduction in cash flow expectations were due to deterioration, or if the change in cash flow expectation was related to noncredit events. This cash flow analysis was used to evaluate the need for a provision for loan and lease losses and/or prospective yield adjustments for the acquired portfolio. Upon adoption of ASU 2016-13, the Company did not reassess whether previously recognized purchased credit impaired loans accounted for under prior accounting guidance met the criteria of a purchased credit deteriorated (PCD) loan as of the date of adoption. PCD loans are initially recorded at fair value along with an ACL determined using the same methodology as originated loans. The sum of the loan's purchase price and ACL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the ACL are recorded through provision for credit losses. As of March 31, 2020, there were no PCD loans in the Company's portfolios.

Allowance for Loan and Lease Losses Methodology
Management has established a methodology to determine the adequacy of the allowance for loan and leasecredit losses that assesses the risks and losses inherent inexpected on the loan and lease portfolio. Additions to the allowance for loan and leasecredit 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 ofTo calculate the allowance, for loan and lease losses onmanagement uses models developed by a quarterly basis. For purposes of determining the allowance for loan and lease losses, the Company has segmented certain loans and leases in the portfolio by product type into the following segments: (1) commercial real estate loans, (2) commercial loans and leases, and (3) consumer loans. Portfolio segments are further disaggregated into classes based on the associated risks within the segments.third party. The models include: Commercial real estate (CRE) lifetime, Commercial and industrial (C&I) lifetime, Retail lifetime, C&I historical, and Retail historical. Lifetime loss rate models calculate the expected losses over the life of the loan based on loan attributes and reasonable, supportable economic forecasts. Historical loss rate models apply a loss rate to the outstanding balance of the loan. Management uses historical loss rates for condominium association, auto, and government lease portfolio segments because these loans have distinct, historical, or expected loss patterns and a de minimus effect on the overall allowance and provision.
Management elected to use multiple economic forecasts in determining the reserve to account for economic uncertainty. The forecasts include various projections of GDP, interest rates, property price indices, and employment measures. The forecasts are divided into three classes: commercial real estateprobability-weighted in accordance with best practices and available information at the time of the calculation execution. Scenario weighting and model parameters are reviewed for each calculation and are subject to change. The models recognize that the life of a loan may exceed the economic forecast therefore the models employ mean reversion techniques to predict credit losses for loans multi-family mortgage loans,that are expected to mature beyond the forecast period. The March 31, 2020 forecasts reflect the immediate and construction loans. Commercial loanslonger-term effects of the COVID-19 pandemic as well as the associated policies and leasesprovision provided by local and national authorities.
The CRE lifetime loss rate, C&I lifetime loss rate, and Retail lifetime loss rate models were developed using the historical loss experience of all banks in the model’s developmental dataset. Banks in the model’s developmental dataset may have different loss experiences as well as variances in operational and underwriting procedures from the Company, and therefore, the Company calibrates expected losses for each model using a scalar. Each scalar was calculated by examining the loss rates of peer banks that have similar operations and asset bases. Peer group loss rates were used in the scalar calculation because management believes the peer group’s historical losses provide a better reflection of the Company’s current portfolio and operating procedures than the Company’s historical losses. Qualitative adjustments are divided into three classes: commercial loans which include taxi medallion loans, equipment financing, and loans to condominium associations. Consumer loans are divided into three classes: residential mortgage loans, home equity loans, and other consumer loans. A formula-based credit evaluation approach isalso applied to each group, coupled with an analysisselect segments of certainthe loan portfolio where applicable.
Specific reserves are established for loans for impairment. For each class of loan, management makes significant judgments in selecting the estimation method that fits the credit characteristics of its class and portfolio segment as set forth below.

The general allowance related to loans collectivelyindividually evaluated for impairment when amortized cost basis is determined using a formula-based approach utilizing the risk ratings of individual credits and loss factors derived from historic portfolio loss rates, which include estimates of incurred losses over an estimated loss emergence period (“LEP”). The LEP was generated utilizing a charge-off

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

Specific valuation allowances are established for impaired originated loans with book values greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent impaired loans, for anywhen there is an excess of a loan's book balanceamortized cost basis over the fair value of its underlying collateral.

characteristics with other financial assets they are established for acquired loans with deterioration in the discounted present value of expected future cash flows since acquisitions or, in the case of collateral dependent impaired loans, for any increase in the excess of a loan's book balance greater than the fair value of its underlying collateral. A specific valuation allowance for losses on troubled debt restructured ("TDR") loans is determined by comparing the net carrying amount of the troubled debt restructured loan with the restructured loan's cash flows discounted at the original effective rate. Impairedevaluated individually. Individually evaluated loans are reviewed quarterly with adjustments made to the calculated reserve as necessary.

Beginning January 1, 2020, the Company implemented the CECL methodology to calculate the allowance for credit losses. As of January 1, 2020, the allowance for loan and lease losses increased by $6.6 million as a result of the adoption of CECL. Prior to January 1, 2020, the Company calculated the allowance for loan and lease losses using the incurred losses methodology.
The general allowance for loan and lease losses was $107.9 million as of March 31, 2020, compared to $59.3 million as of December 31, 2019. The increase in general allowance for loan and lease losses was driven by the effect of the latest available economic forecast of the COVID-19 pandemic on the Company's loan and lease portfolios. The specific allowance for loan and lease losses was $5.3 million as of March 31, 2020, compared to $1.8 million as of December 31, 2019. The specific allowance increased by $3.5 million during the three months ended March 31, 2020 primarily due to the reserves of $2.2 million for an individually evaluated commercial relationship and $1.7 million for another individually evaluated commercial reals estate relationship during the quarter.
As of September 30, 2017,March 31, 2020, 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 inover the lifetime of the Company’s loan portfolios.

As of September 30, 2017, the Company had a portfolio of approximately $27.1 million in loans secured by taxi medallions issued by the cities of Boston and Cambridge. As of December 31, 2016, this portfolio was approximately $31.1 million. Application-based mobile ride services, such as Uber and Lyft, have generated increased competition in the transportation sector, resulting in a reduction in taxi utilization and, as a result, a reduction in the collateral value and credit quality of taxi medallion loans. This has increased the likelihood that loans secured by taxi medallions may default, or that the borrowers may be unable to repay these loans at maturity, potentially resulting in an increase in past due loans, troubled debt restructurings, and charge-offs. The Company’s allowance calculation included a further segmentation of the commercial loans and leases to reflect the increased risk in the Company’s taxi medallion portfolio. This allowance calculation segmentation represents management’s estimations of the current risks associated with the portfolio.

As of September 30, 2017, the Company had an allowance for loan and lease losses associated with taxi medallion loans of $7.2 million of which $5.7 million were specific reserves and $1.5 million was a general reserve. As of December 31, 2016, the Company had an allowance for loan and lease losses associated with taxi medallion loans of $1.3 million of which $0.1 million were specific reserves and $1.2 million was a general reserve. The increase in the allowance for loan and leases associated with taxi medallion loans was primarily driven by the increase in specific reserves due to changes in the underlying collateral value of taxi medallions and the increase in general reserve due to the increase in the historical loss factor applied to the taxi medallion loans. The total troubled debt restructured loans and leases secured by taxi medallions increased by $0.6 million from $6.1 million at December 31, 2016 to $6.7 million at September 30, 2017 due to six taxi medallion relationships which were restructured during the first quarter of 2017. The total loans and leases secured by taxi medallions that were placed on nonaccrual increased to $15.1 million at September 30, 2017 from $13.4 million at December 31, 2016 due to the six restructured taxi medallion relationships mentioned above which were placed on nonaccrual status. In addition, further declines in demand for taxi services or further deterioration in the value of taxi medallions may result in higher delinquencies and losses beyond that provided for in the allowance for loan and lease losses.

The general allowance for loan and lease losses was $57.9 million as of September 30, 2017, compared to $53.5 million as of December 31, 2016. The general allowance for loan and lease losses increased by $4.4 million during the nine months ended September 30, 2017, as a result of the continued growth in the Company's loan portfolios and the increase in historical loss factors applied to taxi medallion and commercial real estate loan portfolios.

The specific allowance for loan and lease losses was $7.5 million as of September 30, 2017, compared to $0.2 million as of December 31, 2016. The specific allowance increased by $7.3 million during the nine months ended September 30, 2017,

primarily due to the reduction in collateral values for taxi medallion loans and the increase in specific reserves for one commercial loan.

Credit Quality Assessment
At the time of loan origination, a rating is assigned based on the capacity to pay and general financial strength of the borrower, the value of assets pledged as collateral, and the evaluation of third party support such as a guarantor. The Company continually monitors the credit 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,adversely risk-rated, 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.restructuring ("TDR") loan.
The Company reviews numerous credit quality indicators when assessing the risk in its loan portfolio. For all loans, the Company utilizes an eight-grade loan rating system, which assigns a risk rating to each borrower based on a number of quantitative and qualitative factors associated with a loan transaction. Factors considered include industry and market conditions; position within the industry; earnings trends; operating cash flow; asset/liability values; debt capacity; guarantor strength; management and controls; financial reporting; collateral; and other considerations. In addition, the Company's independent loan review group evaluates the credit quality and related risk ratings in all loan portfolios. The results of these reviews are reported to the Risk Committee of the Board of Directors on a periodic basis and annually to the Board of Directors. For the consumer loans, the Company heavily relies on payment status for calibrating credit risk.
The ratings categories used for assessing credit risk in the commercial real estate, multi-family mortgage, construction, commercial, equipment financing, condominium association and other consumer loan and lease classes are defined as follows:
1 -4 Rating—Pass
Loan rating grades "1" through "4" are classified as "Pass," which indicates borrowers are performing in accordance with the terms of the loan and are less likely to result in loss due to the capacity of the borrower to pay and the adequacy of the value of assets pledged as collateral.
5 Rating—Other Assets Especially Mentioned ("OAEM")
Borrowers exhibit potential credit weaknesses or downward trends deserving management's attention. If not checked or corrected, these trends will weaken the Company's asset and position. While potentially weak, currently these borrowers are marginally acceptable; no loss of principal or interest is envisioned.

Notes to Unaudited Consolidated Financial Statements (Continued)

6 Rating—Substandard
Borrowers exhibit well defined weaknesses that jeopardize the orderly liquidation of debt. Substandard loans may be inadequately protected by the current net worth and paying capacity of the obligors or by the collateral pledged, if any. Normal repayment from the borrower is in jeopardy. Although no loss of principal is envisioned, there is a distinct possibility that a partial loss of interest and/or principal will occur if the deficiencies are not corrected. Collateral coverage may be inadequate to cover the principal obligation.
7 Rating—Doubtful
Borrowers exhibit well-defined weaknesses that jeopardize the orderly liquidation of debt with the added provision that the weaknesses make collection of the debt in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Serious problems exist to the point where partial loss of principal is likely.
8 Rating—Definite Loss
Borrowers deemed incapable of repayment. Loans to such borrowers are considered uncollectible and of such little value that continuation as active assets of the Company is not warranted.
Assets rated as "OAEM," "substandard" or "doubtful" based on criteria established under banking regulations are collectively referred to as "criticized" assets.

At and for the Nine Months Ended September 30, 2017 and 2016

Commercial Real Estate Loans—As of September 30, 2017, loans outstanding in the three classes within this segment expressed as a percentage of total loans and leases outstanding were as follows: commercial real estate loans -- 37.6%; multi-family mortgage loans -- 13.2%; and construction loans -- 2.9%.
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 September 30, 2017, loans and leases outstanding in the three classes within this segment expressed as a percent of total loans and leases outstanding were as follows: commercial loans and leases -- 12.2%; equipment financing loans -- 14.9%; and loans to condominium associations -- 1.0%.
(1) Loans and leases in this portfolio that are on nonaccrual status and/or risk-rated "substandard" or worse are evaluated on an individual basis for impairment. For non-impaired commercial loans and leases, loss factors are applied to outstanding loans by risk rating for each of the three classes in the portfolio.
Consumer Loans—As of September 30, 2017, loans outstanding within the four classes within this segment expressed as a percent of total loans and leases outstanding were as follows: residential mortgage loans -- 11.6%, home equity loans -- 6.3%, and other consumer loans -- 0.3%.
Significant risk characteristics related to the residential mortgage and home equity loan portfolios are the geographic concentration of the properties financed within selected communities in the greater Boston and Providence metropolitan areas. The payment status and loan-to-value ratio are the primaryacquired with deteriorated 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.always accruing.
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 loans and leases risk-rated "substandard" or worse are considered impaired. The Company has also defined the population of impaired loans to include nonaccrual loans and troubled debt restructured ("TDR")TDR loans.
When Impaired loans and leases which do not share similar risk characteristics with other loans are individually evaluated for credit losses. Specific reserves are established for loans and leases with deterioration in the ultimate collectabilitypresent value of expected future cash flows or, in the total principalcase of an impaired loan or lease iscollateral-dependent loans and leases, any increase 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 isamortized cost basis over the fair value of the underlying collateral discounted for estimated selling costs. In contrast, the loans and leases which share similar risk characteristics and are not included in the individually evaluated population are collectively evaluated for credit losses.

The Coronavirus Aid, Relief and Economic Relief ("CARES") Act and regulatory guidance recently issued by the Federal banking agencies provides that certain short-term loan modifications to borrowers experiencing financial distress as a result of the economic impacts created by the COVID-19 pandemic are not required to be treated as TDRs under GAAP. As such, the Company suspended TDR accounting for COVID-19 pandemic related loan modifications meeting the loan modification criteria set forth under the CARES Act or as specified in the regulatory guidance. Further, loans granted payment deferrals related to COVID-19 pandemic are not required to be reported as past due or placed on non-accrual status (provided the loans were not past due or on non-accrual status prior to the deferral). Please refer to Note 14, Subsequent Events for further information regarding loans and leases modified under the CARES Act.

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

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

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 September 30, 2017March 31, 2020 or December 31, 2016.

2019.
Derivatives not designated as hedges are not speculative but rather result from a service the Company provides to certain customers for a fee. The Company executes loan level derivative products such as interest-rate swap agreements with commercial banking customers to aid them in managing their interest-rate risk. The interest-rate swap contracts allow the commercial banking customers to convert floating-rate loan payments to fixed-rate loan payments. The Company concurrently enters into offsetting swaps with a third party financial institution, effectively minimizing its net risk exposure resulting from such transactions. The third-party financial institution exchanges the customer's fixed-rate loan payments for floating-rate loan payments. As the interest-rate swap agreements associated with this program do not meet hedge accounting requirements, changes in the fair value are recognized directly in earnings.
The Company utilizes risk participation agreements with other banks participating in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. Risk participation agreements are derivative financial instruments and are recorded at fair value. These derivatives are not designated as hedges and therefore, changes in fair value are recorded directly through earnings at each reporting period.
Under a risk participation-out agreement, a derivative asset, the Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower, for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the 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 liquidity risk associated with these foreign exchange contracts, the Company enters into similar offsetting positions.
Asset derivatives and liability derivatives are included in other assets and accrued expenses and other liabilities on the unaudited consolidated balance sheets.
The following tables presentspresent the Company's customer related derivative positions for the periods indicated below for those derivatives not designated as hedging.

As of December 31, 2016, the Company held no risk participation-in agreements. As of December 31, 2016, the fair value of the foreign exchange contracts was nominal.
The Company has agreements with certain of its derivative counterparties that contain credit-risk-related contingent provisions. These provisions provide the counterparty with the right to terminate its derivative positions and require the Company to settle its obligations under the agreements if the Company defaults on certain of its indebtedness or if the Company fails to maintain its status as a well-capitalized institution.
(9) Stock Based Compensation
As of September 30, 2017,March 31, 2020, the Company had three2 active recognition and retentionequity plans: the 2003 Recognition and Retention Plan (the "2003 RRP") with 1,250,000 authorized shares, the 2011 Restricted Stock Award Plan ("2011 RSA") with 500,000 authorized shares and the 2014 Equity Incentive Plan ("2014 Plan") with 1,750,000 authorized shares. The 2003 RRP, the 2011 RSA and the 2014 Plan are collectively referred to as the "Plans". The purpose of the Plans is to promote the long-term financial success of the Company and its subsidiaries by providing a means to attract, retain and reward individuals who contribute to such success and to further align their interests with those of the Company's stockholders.
Of the awarded shares, generally 50% vest ratably over three years with one-third of such shares vesting at each of the first, second and third anniversary dates of the awards. These are referred to as "time-based shares". The remaining 50% of each award has a cliff vesting schedule and will vest three years after the award date based on the level of the Company's achievement of identified performance targets in comparison to the level of achievement of such identified performance targets by a defined peer group comprised of 1715 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 usually forfeited. Dividends declared with respect to shares awarded will be held by the Company and paid to the participant only when the shares vest.
Under all the Plans, shares of the Company's common stock were reserved for issuance as restricted stock awards to officers, employees, and non-employee directors of the Company. Shares issued upon vesting may be either authorized but unissued shares or reacquired shares held by the Company as treasury shares. Any shares not issued because vesting requirements are not met will be retired back to treasury and be made available again for issuance under the Plans.
During the three and nine months ended September 30, 2017, 151,083March 31, 2020 and 163,204 shares were issued upon satisfaction of required conditions of the Plans. During the three and nine months ended September 30, 2016, 134,809 and 136,1392019, 0 shares were issued upon satisfaction of required conditions of the Plans.
Total expense for the Plans was $0.7$0.6 million and $0.6$0.9 million for the three months ended September 30, 2017March 31, 2020 and 2016,2019, respectively. Total expense for the Plans was $1.8 million and $1.4 million for the nine months ended September 30, 2017 and

Investment Securities Available-for-Sale
The fair value of investment securities is based principally on market prices and dealer quotes received from third-party and nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's marketable equity securities are priced this way and are included in Level 1. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include GSE debentures, GSE mortgage-related securities, SBA commercial loan asset backed securities, corporate debt securities, and trust preferred securities, all of which are included in Level 2. As of September 30, 2017March 31, 2020 and December 31, 2016,2019, no investment securities were valued using pricing models included in Level 3.
Additionally, management reviews changes in fair value from period to period and performs testing to ensure that prices received from the third parties are consistent with management's expectation of the market. Changes in the prices obtained from the pricing service are analyzed from month to month, taking into consideration changes in market conditions including changes in mortgage spreads, changes in U.S. Treasury security yields and changes in generic pricing of 15-year and 30-year securities. Additional analysis may include a review of prices provided by other independent parties, a yield analysis, a review of average life changes using Bloomberg analytics and a review of historical pricing for a particular security.
Equity Securities Held-for-Trading
The fair value of equity securities held-for-trading is based principally on market prices and dealer quotes received from third-party and nationally-recognized pricing services. The Company's equity securities are priced this way and are included in Level 1 and Level 2. These prices are validated by comparing the primary pricing source with an alternative pricing source when available.
Derivatives and Hedging Instruments
The fair values for the interest-rate swap assets and liabilities, risk participation agreements (RPA in/out), and foreign exchange derivatives 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 and foreign exchange rates where applicable.

Credit risk adjustments consider factors such as the likelihood of default by the Company and its counterparties, its net exposures and remaining contractual life. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position. Refer also to Note 8, "Derivatives and Hedging Activities."
There were no transfers between levels for assets and liabilities recorded at fair value on a recurring basis during the three and nine months ended September 30, 2017March 31, 2020 and 2016,2019, respectively.

Collateral-Dependent Impaired Loans and Leases
For nonperforming loans and leases where the credit quality of the borrower has deteriorated significantly, fair values of the underlying collateral were estimated using purchase and sales agreements (Level 2), or comparable sales or recent appraisals (Level 3), adjusted for selling costs and other expenses.
Other Real Estate Owned
The Company records OREO at the lower of cost or fair value. In estimating fair value, the Company utilizes purchase and sales agreements (Level 2) or comparable sales, recent appraisals or cash flows discounted at an interest rate commensurate with the risk associated with these cash flows (Level 3), adjusted for selling costs and other expenses.
Repossessed Assets
Repossessed assets are carried at estimated fair value less costs to sell based on auction pricing (Level 2).

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

Investment Securities Held-to-Maturity
The fair values of certain investment securities held-to-maturity are estimated using market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include GSE debentures, GSE MBSs, and municipal obligations, all of which are included in Level 2. Additionally, fair values of foreign government obligations are estimated using pricing models 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, 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). TheUsing the exit price valuation method, the Company discounts the contractual cash flows for each loan category using interest rates currently being offered for loans with similar terms to borrowers of similar quality and incorporates estimates of future loan prepayments. This method of estimating fair value does not incorporate the exit price concept of fair value.
Restricted Equity Securities
The fair values of certain restricted equity securities are estimated using observable inputs adjusted for other unobservable information, including but not limited to probability assumptions and similar discounts where applicable. These restricted equity securities are considered to be Level 3.

At and for the Nine Months Ended September 30, 2017 and 2016

Deposits
The fair values of deposit liabilities with no stated maturity (demand, NOW, savings and money market savings accounts) are equal to the carrying amounts payable on demand. The fair value of certificates of deposit represents contractual cash flows discounted using interest rates currently offered on deposits with similar characteristics and remaining maturities. The fair value estimates for deposits do not include the benefit that results from the low-cost funding provided by the Company's core deposit relationships (deposit-based intangibles).
Borrowed Funds
The fair value of federal funds purchased is equal to the amount borrowed. The fair value of FHLBB advances and repurchase agreements represents contractual repayments discounted using interest rates currently available for borrowings with similar characteristics and remaining maturities. The fair values reported for retail repurchase agreements are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on borrowings with similar characteristics and maturities. The fair values reported for subordinated deferrable interest debentures are based on the discounted value of contractual cash flows. The discount rates used are representative of approximate rates currently offered on instruments with similar terms and maturities.
(12) Commitments and Contingencies
Off-Balance Sheet Financial Instruments
The Company is party to off-balance sheet financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby and commercial letters of credits,credit, and loan level derivatives. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received.
The contract amounts reflect the extent of the involvement the Company has in particular classes of these instruments. Such commitments involve, to varying degrees, elements of credit risk and interest-rate risk in excess of the amount recognized in the consolidated balance sheets. The Company's exposure to credit loss in the event of non-performance by the counterparty is represented by the fair value of the instruments. The Company uses the same policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee by the customer. Since some of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if any, is based on management's credit evaluation of the borrower.
Standby and commercial letters of creditscredit 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.
From time to time, the Company enters into loan level derivatives, risk participation agreements or foreign exchange contracts with commercial customers and third-party financial institutions. These derivatives allow the Company to offer long-term fixed-rate commercial loans while mitigating the interest-rate or foreign exchange risk of holding those loans. In a loan level derivative transaction, the Company lends to a commercial customer on a floating-rate basis and then enters into ana loan level derivative with that customer. Concurrently, the Company enters into offsetting swaps with a third-party financial institution, effectively minimizing its net interest-rate risk exposure resulting from such transactions.
The fair value of derivative assets and liabilities was $10.0$157.5 million and $10.0$155.4 million, respectively, as of September 30, 2017.March 31, 2020. The fair value of derivative assets and liabilities was $9.8$60.6 million and $9.7$59.7 million, respectively, as of December 31, 2016.2019.

Lease Commitments
The Company leases certain office space under various noncancellable operating leases.leases as well as certain other assets. These leases have original terms ranging from 53 years to over 25 years. Certain leases contain renewal options and escalation clauses which can increase rental expenses based principally on the consumer price index and fair market rental value provisions. All of the Company's current outstanding leases are classified as operating leases.
The Company considered the following criteria when determining whether a contract contains a lease, the existence of an identifiable asset and the right to obtain substantially all of the economic benefits from use of the asset through the period. The Company used the FHLB classic advance rates available as of the date of the lease origination as the discount rate to determine the net present value of the remaining lease payments.

Legal Proceedings
In the normal course of business, there are various outstanding legal proceedings. In the opinion of management, after consulting with legal counsel, the consolidated financial position and results of operations of the Company are not expected to be affected materially by the outcome of such proceedings.
(13) 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 in gross 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.
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 represents the service charges assessed to customers who hold deposit accounts at the Banks.
(14) Subsequent Events
On March 27, 2020, Congress passed, and the President signed, the CARES Act to address the economic effects of the COVID-19 pandemic.
Paycheck Protection Program. The CARES Act appropriated $349 billion for “paycheck protection loans” through the U.S. Small Business Administration's (“SBA’s”) Paycheck Protection Program (“PPP”). The amount appropriated was subsequently increased to $659 billion. Loans under the PPP that meet SBA requirements may be forgiven in certain circumstances, and are 100% guaranteed by SBA. As of the filing date, the Banks have obtained SBA approval for 2,923 PPP loans totaling $589 million. All PPP loans have been funded. PPP loans are fully guaranteed by the U.S. government, have a two-year term and earn interest at rate of 1%. We currently expect a significant portion of these loans will ultimately be forgiven by the SBA in accordance with the terms of the program. In conjunction with the PPP, the FRB has created a lending facility for qualified financial institutions. The Paycheck Protection Program Liquidity Facility (the “PPPLF”) will extend credit to depository institutions with a term of up to two years at an interest rate of 0.35%. Only loans issued under the PPP can be pledged as collateral to access the facility. The Company began participating in the PPPLF in April 2020.
Troubled Debt Restructuring Relief. From March 1, 2020 through the earlier of December 31, 2020 or 60 days after the termination date of the national emergency declared by the President on March 13, 2020 concerning the COVID-19 outbreak (the “national emergency”), a financial institution may elect to suspend the requirements under accounting principles generally accepted in the U.S. for loan modifications related to the COVID-19 pandemic that would otherwise be categorized as a troubled debt restructured, including impairment accounting. This troubled debt restructuring relief applies for the term of the loan modification that occurs during the applicable period for a loan that was not more than 30 days past due as of December 31, 2019. Financial institutions are required to maintain records of the volume of loans involved in modifications to which troubled debt restructuring relief is applicable. As of the filing date, the banks have granted 5,293 short-term deferments on loan balances of $1.5 billion, which represented 21% of total loan balances as of March 31, 2020. These short-term deferments are not classified as troubled debt restructured loans and will not be reported as past due provided that they are performing in accordance with the modified terms.
CECL Delay. Banks, savings associations, credit unions, bank holding companies and their affiliates are not required to comply with ASU 2016-13, including CECL, from the date of the law’s enactment until the earlier of the end of the national emergency or December 31, 2020. On March 27, 2020, the Federal Reserve, the FDIC and the Office of the Comptroller of the Currency issued an interim final rule that allows banking organizations that are required to adopt CECL this year to mitigate the estimated cumulative regulatory capital effects for up to two years. The relief afforded by the CARES Act and interim final rule is in addition to the three-year transition period already in place. The Company adopted CECL effective January 1, 2020.
Reduction of the Community Bank Leverage Ratio. The CARES Act reduced the community bank leverage ratio from 9% to 8% until the earlier of the end of the national emergency or December 31, 2020. In response to the CARES Act, federal banking regulators set the community bank leverage ratio at 8% for the remainder of 2020, 8.5% for 2021 and 9% thereafter.

Revival of Bank Debt Guarantee Program. The CARES Act amends the Dodd-Frank Act to provide the FDIC with the authority to guarantee bank-issued debt and noninterest-bearing transaction accounts that exceed the FDIC's $250,000 limit through December 31, 2020. The FDIC has discretion to determine whether and how to exercise this authority.
Forbearance. The CARES Act codifies in part guidance from state and federal regulators and government-sponsored enterprises, including the 60-day suspension of foreclosures on federally-backed mortgages and requirements that servicers grant forbearance to borrowers affected by COVID-19.
Moratorium on Negative Credit Reporting. Any furnisher of credit information that agrees to defer payments, forbear on any delinquent credit or account, or provide any other relief to consumers affected by the COVID-19 pandemic must report the credit obligation or account as current if the credit obligation or account was current before the accommodation.

Introduction
Brookline Bancorp, Inc., a Delaware corporation, operates as a multi-bank holding company for Brookline Bank and its subsidiaries; Bank Rhode Island and its subsidiaries ("BankRI"); First Ipswich Bank and its subsidiaries ("First Ipswich"); and Brookline Securities Corp. As previously disclosed, the merger of First Ipswich Bank into Brookline Bank was completed in the first quarter of 2020.
As a commercially-focused financial institution with 51 full-service banking offices throughout greater Boston, the north shore of Massachusetts and Rhode Island, the Company, through Brookline Bank BankRI and First Ipswich (the “Banks”),BankRI, 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, primarily27.8% of which is in the greater New York and New Jersey metropolitan area.area and 72.2% of which is in other areas in the United States of America as of March 31, 2020.
The Company focuses its business efforts on profitably growing its commercial lending businesses, both organically and through acquisitions. The Company’s customer focus, multi-bank structure, and risk management are integral to its organic growth strategy and serve to differentiate the Company from its competitors. As full-service financial institutions, the Banks and their subsidiaries focus their efforts on developing and deepening long-term banking relationships with qualified customers through a full complement of products, and excellent customer service, and strong risk management.
The Company manages the Banks under a uniform strategic objectives,objective, with one set of uniform policies consistently applied by one executive management team. Within this environment, the Company believes that the ability to make customer decisions locally enhances management's motivation, service levels and, as a consequence, the Company's financial results. As such, while most back-office functions are consolidated at the holding company level, branding and decision-making, including credit decisions and pricing, remain largely local in order to better meet the needs of bank customers and further motivate the

Banks’ commercial, business and retail bankers. 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 the economy has improved in 2017, theThe Company expects the operating environment 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”).FRB. A sustained, low interest rate environment with a flat interest rate curve may negatively impact on the Company's yields and net interest margin. While the companyCompany is slightly asset sensitive and should benefit from rising rates, these rate increaseschanges in interest rates could also precipitate a change in the mix and volume of the Company's deposits and 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 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 areis also subject to regulation under the laws of the Commonwealth of Massachusetts and the jurisdiction of the Massachusetts Division of Banks. As a Rhode Island-chartered financial institution, BankRI is also subject to regulation under the laws of the State of Rhode Island and the jurisdiction of the Banking Division of the Rhode Island Department of Business Regulation. The FDIC continues to insure each of the Banks’ deposits up to $250,000 per depositor. Additionally, asAs previously disclosed, on July 31, 2019, Brookline Bank converted its charter from a Massachusetts savings bank to a Massachusetts-chartered savings bank, Brookline Bank is also insured bytrust company and ended its membership in the Depositors Insurance Fund (“DIF”), a private industry-sponsored company. Thefund which insures Massachusetts-chartered savings bank deposit balances in excess of federal deposit insurance coverage. Brookline Bank’s growth in deposit size necessitated Brookline Bank’s withdrawal from the DIF insures savings bankand the concurrent charter conversion of Brookline Bank. Brookline Bank’s deposit accounts will continue to be insured by the deposit insurance fund of the FDIC up to applicable limits. Excess deposits that were insured by the DIF on July 31, 2019 will continue to be insured by the DIF until July 31, 2020.  Term 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 fromcoverage will continue to be insured by the FDIC and the DIF.DIF until they reach maturity.
The Company’s common stock is traded on the Nasdaq Global Select MarketSM under the symbol “BRKL.”
Regulatory Developments - The CARES Act
On March 27, 2020, Congress passed, and the President signed, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) to address the economic effects of the COVID-19 pandemic.
Paycheck Protection Program. The CARES Act appropriated $349 billion for “paycheck protection loans” through the SBA’s PPP. The amount appropriated was subsequently increased to $659 billion. Loans under the PPP that meet SBA requirements may be forgiven in certain circumstances, and are 100% guaranteed by SBA. As of the filing date, Brookline Bank and Bank Rhode Island have obtained SBA approval for 2,923 PPP loans totaling $589 million. All PPP loans have been funded. PPP loans are fully guaranteed by the U.S. government, have a two-year term and earn interest at rate of 1%. We currently expect a significant portion of these loans will ultimately be forgiven by the SBA in accordance with the terms of the program.

The PPPLF will extend credit to depository institutions with a term of up to two years at an interest rate of 0.35%. Only loans issued under the PPP can be pledged as collateral to access the facility. The Company is participating in the PPPLF program.
Troubled Debt Restructuring Relief. From March 1, 2020 through the earlier of December 31, 2020 or 60 days after the termination date of the national emergency, a financial institution may elect to suspend the requirements under accounting principles generally accepted in the U.S. for loan modifications related to the COVID-19 pandemic that would otherwise be categorized as a troubled debt restructured, including impairment accounting. This troubled debt restructuring relief applies for the term of the loan modification that occurs during the applicable period for a loan that was not more than 30 days past due as of December 31, 2019. Financial institutions are required to maintain records of the volume of loans involved in modifications to which troubled debt restructuring relief is applicable. As of the filing date, the Banks have granted approximately 5,293 short-term deferments on loan balances of $1.5 billion, which represented 21% of total loan balances as of March 31, 2020. These short-term deferments are not classified as troubled debt restructured loans and will not be reported as past due provided that they are performing in accordance with the modified terms.
CECL Delay. Banks, savings associations, credit unions, bank holding companies and their affiliates are not required to comply with ASU 2016-13, including CECL, from the date of the law’s enactment until the earlier of the end of the national emergency or December 31, 2020.

Massachusetts COVID-19 Emergency Legislation
On April 20, 2020, legislation enacted in Massachusetts in response to the COVID-19 emergency declared by Governor Baker was signed into law by the Governor. The legislation establishes a temporary moratorium on foreclosures on one- to four-family, owner occupied residential real estate in Massachusetts. The legislation also requires a creditor to grant to a borrower of a mortgage loan secured by one- to four-family, owner occupied residential real estate in Massachusetts a forbearance of up to 180 days, if requested by the borrower, who must affirm that the borrower has experienced a financial impact from the COVID-19 pandemic. A borrower is entitled to request a forbearance while the legislation is in effect even if the borrower is already in default. In connection with a forbearance, a creditor may not charge fees, penalties or interest beyond the amounts scheduled and calculated as if the borrower made all contractual payments on time and in full under the terms of the relevant loan agreement. The legislation specifies that a payment subject to forbearance shall be added to the end of the term of the loan unless otherwise agreed by the parties. The legislation also prohibits a creditor from furnishing negative information to a consumer reporting agency related to mortgage payments subject to forbearance. Because the legislation was enacted on an emergency basis, it went into effect immediately upon being signed into law. The legislation provides that the temporary moratorium on foreclosures expires 120 days after the effective date of the legislation, which is August 18, 2020, or 45 days after the COVID-19 emergency declaration has been lifted, whichever is sooner. The Governor may extend the moratorium in increments of up 90 days as long as the moratorium ends not later than 45 days after the COVID-19 emergency declaration has been lifted. A borrower may request a forbearance under the legislation at any time while the foreclosure moratorium is in effect.

Critical Accounting Policies
The SEC defines “critical accounting policies” as those involving significant judgments and difficult or complex assumptions by management, often as a result of the need to make estimates about matters that are inherently uncertain or variable, which have, or could have, a material impact on the carrying value of certain assets or net income. The preparation of financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. As discussed in the Company’s 20162019 Annual Report on Form 10-K, management has identified the valuation of available-for-sale securities, accounting for assets and liabilities acquired, the determination of the allowance for loan and lease losses, the review of goodwill and intangibles for impairment, income tax accounting, and valuation of deferred tax assets as the Company’s most critical accounting policies.

As a result of the adoption of ASU 2016-13 effective January 1, 2020, the Company updated its critical accounting policy for the allowance of credit losses on loans. The updates in this standard replace the incurred loss impairment methodology in current GAAP with the CECL methodology. The CECL methodology incorporates current condition, and "reasonable and supportable" forecasts, as well as prepayments, to estimate loan losses over the life of the loan. See Note 5: "Allowance for Loan and Lease Losses" for further discussion on the new policy and processes.

Recent Accounting Developments

In March 2020, the FASB issued ASU 2020-04, " Reference Rate Reform (Topic 848)-Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04") to provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to certain contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships existing as of December 31, 2022, for which an entity has elected certain optional expedients provided that those elections are retained through the end of the hedging relationship. The amendments in this update are effective for all entities as of March 12, 2020 through December 31,2022 and do not apply to contract modifications made after December 31, 2022. The Company has not yet adopted the amendments in this update and is currently in the process of reviewing its contracts and existing processes in order to assess the risks and potential impact to the Company.

In August 2018, FASB issued ASU 2018-14, "Compensation-Retirement Benefits-Defined Benefit Plans-General

(Subtopic 715-20)" ("ASU 2018-14"), to modify the disclosure requirements for employers that sponsor defined benefit pension or other
postretirement plans. This ASU is effective for fiscal years beginning after December 15, 2020, for public business entities and
for fiscal years beginning 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 March 31, 2020.




Non-GAAP Financial Measures and Reconciliation to GAAP
In addition to evaluating the Company’s results of operations in accordance with GAAP, management periodically supplements this evaluation with an analysis of certain non-GAAP financial measures, such as operating earnings metrics, the return on average tangible assets, return on average tangible equity, the tangible equity ratio, tangible book value per share, and 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.ratio. Management believes that these non-GAAP financial measures provide information useful to investors in understanding the Company’s underlying operating performance and trends, and facilitates comparisons with the performance assessment of financial performance, including non-interest expense control, while the tangible equity ratio and tangible book value per share are used to analyze the relative strength of the Company’s capital position.

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.

The Company's current policy is that the aggregate amount of loans outstandinga total credit exposure to any one borrower or related entitiesobligor relationship may not exceed $35.0$50.0 million unless approved by the BoardCompany's Credit Committee, a committee of the Company's Board of Directors.
Committee. As of September 30, 2017,March 31, 2020, there were ten2 borrowers with loans and

commitments over $35.0$50.0 million. The total of those loans and commitments were $424.8was $107.3 million, or 6.5%1.32% of total loans and commitments, as of September 30, 2017.March 31, 2020. As of December 31, 2019, there were 3 borrowers with loans and commitments over $50.0 million. The total of those loans and commitments was $194.3 million, or 2.40% of total loans and commitments, as of December 31, 2019.
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 53.7%55.1% of total loans and leases outstanding as of September 30, 2017.March 31, 2020.
Typically, commercial real estate loans are larger in size and involve a greater degree of risk than owner-occupied residential mortgage loans. Loan repayment is usually dependent on the successful operation and management of the properties and the value of the properties securing the loans. Economic conditions can greatly affect cash flows and property values.
A number of factors are considered in originating commercial real estate and multi-family mortgage loans. The qualifications and financial condition of the borrower (including credit history), as well as the potential income generation and the value and condition of the underlying property, are evaluated. When evaluating the qualifications of the borrower, the Company considers the financial resources of the borrower, the borrower's experience in owning or managing similar property and the borrower's payment history with the Company and other financial institutions. Factors considered in evaluating the underlying property include the net operating income of the mortgaged premises before debt service and depreciation, the debt service coverage ratio (the ratio of cash flow before debt service to debt service), the use of conservative capitalization rates, and the ratio of the loan amount to the appraised value. Generally, personal guarantees are obtained from commercial real estate loan borrowers.
Commercial real estate and multi-family mortgage loans are typically originated for terms of five to fifteen years with amortization periods of 20 to 30 years. Many of the loans are priced at inception on a fixed-rate basis generally for periods ranging from two to five years with repricing periods for longer-term loans. When possible, prepayment penalties are included in loan covenants on these loans. For commercial customers who are interested in loans with terms longer than five years, the Company offers loan level derivatives to accommodate customer need.
The Company's urban and suburban market area is characterized by a large number of apartment buildings, condominiums and office buildings. As a result, commercial real estate and multi-family mortgage lending has been a significant part of the Company's activities for many years. These types of loans typically generate higher yields, but also involve greater credit risk. Many of the Company's borrowers have more than one multi-family or commercial real estate loan outstanding with the Company.
The Company's commercial real estate portfolio is composed primarily of loans secured by apartment buildings ($741.6927.7 million), office buildings ($637.8722.8 million), retail stores ($507.2606.2 million), industrial properties ($358.6451.2 million), mixed-use properties ($214.1323.1 million), lodging services ($108.3148.5 million) and to food services ($42.761.7 million) as of September 30, 2017.March 31, 2020. At that date, over 97.2%approximately 97.0% of the commercial real estate loans outstanding were secured by properties located in New England.
Construction and development financing is generally considered to involve a higher degree of risk than long-term financing on improved, occupied real estate and thus has lower concentration limits than do other commercial credit classes. Risk of loss on a construction loan is largely dependent upon the accuracy of the initial estimate of construction costs, the estimated time to sell or rent the completed property at an adequate price or rate of occupancy, and market conditions. If the estimates and projections prove to be inaccurate, the Company may be confronted with a project which, upon completion, has a value that is insufficient to assure full loan repayment.
Criteria applied in underwriting construction loans for which the primary source of repayment is the sale of the property are different from the criteria applied in underwriting construction loans for which the primary source of repayment is the stabilized cash flow from the completed project. For those loans where the primary source of repayment is from resale of the property, in addition to the normal credit analysis performed for other loans, the Company also analyzes project costs, the attractiveness of the property in relation to the market in which it is located and demand within the market area. For those construction loans where the source of repayment is the stabilized cash flow from the completed project, the Company analyzes

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

Commercial Loans
The Company's commercial loan and lease portfolio is comprised of commercial loans, equipment financing loans and leases and condominium association loans and represented 28.1%26.8% of total loans outstanding as of September 30, 2017.March 31, 2020.
The Company's commercial loan and lease portfolio is composed primarily of loans to small to medium sized businesses ($489.9638.0 million), transportation services ($346.4376.8 million), food services ($152.2 million), recreation services ($145.9 million), food services ($118.1116.0 million), manufacturing ($97.5101.4 million), retail ($87.4 million), and rental and leasing services ($75.9 million) and retail ($70.590.0 million) as of September 30, 2017.March 31, 2020.
The Company provides commercial banking services to companies in its market area. Approximately 47.0%45.3% of the commercial loans outstanding as of September 30, 2017March 31, 2020 were made to borrowers located in New England. The remaining 53.0%54.7% of the commercial loans outstanding were made to borrowers in other areas in the United States of America, primarily by the Company's equipment financing divisions. Product offerings include lines of credit, term loans, letters of credit, deposit services and cash management. These types of credit facilities have as their primary source of repayment cash flows from the operations of a business. Interest rates offered are available on a floating basis tied to the prime rate or a similar index or on a fixed-rate basis referenced on the Federal Home Loan Bank of Boston ("FHLBB") index.
Credit extensions are made to established businesses on the basis of loan purpose and assessment of capacity to repay as determined by an analysis of their financial statements, the nature of collateral to secure the credit extension and, in most instances, the personal guarantee of the owner of the business as well as industry and general economic conditions. The Company also participates in U.S. Government programs such the SBA as the Small Business Administration (the "SBA") in both the 7A program and as an SBA preferred lender.
The Company’s equipment financing divisions focus on market niches in which its lenders have deep experience and industry contacts, and on making loans to customers with business experience. An important part of the Company’s equipment financing loan origination volume comes from equipment manufacturers and existing customers as they expand their operations. The equipment financing portfolio is composed primarily of loans to finance laundry, tow trucks, fitness, dry cleaning and convenience store equipment. Approximately 16.0%24.3% of the commercial loans outstanding in the equipment financing division were made to borrowers located primarily in the greater New York and New Jersey metropolitan area. Typically, the loans are priced at a fixed rate of interest and require monthly payments over their three-3- to seven-year7-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, which is comprised of residential mortgage loans, home equity loans and lines of credit, and other consumer loans, and represented 18.2%18.1% of total loans outstanding as of September 30, 2017.March 31, 2020. The Company focuses its mortgage and home equity lending on existing and new customers within its branch networks in its urban and suburban marketplaces in the greater Boston and Providence metropolitan areas.
The Company originates adjustable- and fixed-rate residential mortgage loans secured by one- to four-family residences. Each residential mortgage loan granted is subject to a satisfactorily completed application, employment verification, credit history and a demonstrated ability to repay the debt. Generally, loans are not made when the loan-to-value ratio exceeds 80% unless private mortgage insurance is obtained and/or there is a financially strong guarantor. Appraisals are performed by outside independent fee appraisers.
In general, the Company maintains three-, five- and seven-year adjustable-rate mortgage loans and ten-year fixed-rate fully amortizing mortgage loans in its portfolio. Fixed-rate mortgage loans with maturities beyond ten years, such as 15- and

30-year fixed-rate mortgages, are generally sold into the secondary market on a servicing-released basis. The Banks act as correspondent banks in these secondary-market transactions. Loan sales in the secondary market provide funds for additional lending and other banking activities.
Underwriting guidelines for home equity loans and lines of credit are similar to those for residential mortgage loans. Home equity loans and lines of credit are limited to no more than 80% of the appraised value of the property securing the loan including the amount of any existing first mortgage liens.

Other consumer loans have historically been a modest part of the Company's loan originations. As of September 30, 2017,March 31, 2020, other consumer loans equaled $15.7$34.8 million, or 0.3%0.5% of total loans outstanding.
Asset Quality
Criticized and Classified Assets
The Company's management rates certain loans and leases as "other assets especially mentionedmentioned" ("OAEM")", "substandard" or "doubtful" based on criteria established under banking regulations.These loans and leases are collectively referred to as "criticized" assets. Loans and leases rated OAEM have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects of the loan or lease at some future date. Loans and leases rated as substandard are inadequately protected by the payment capacity of the obligor or of the collateral pledged, if any. Substandard loans and leases have a well-defined weakness or weaknesses that jeopardize the liquidation of debt and are characterized by the distinct possibility that the Company will sustain some loss if existing deficiencies are not corrected. Loans and leases rated as doubtful have well-defined weaknesses that jeopardize the orderly liquidation of debt and partial loss of principal is likely. As of September 30, 2017,March 31, 2020, the Company had $74.3$62.8 million of total assets, including acquired assets that were designated as criticized. This compares to $70.4$67.2 million of assets designated as criticized as of December 31, 2016.2019. The increasedecrease of $4.4 million in criticized assets was primarily due to the downgradepay-off of severala criticized commercial real estate loans,loan and an upgrade to pass risk rating of another commercial loan, partially offset by the payoffs of severalloans becoming criticized loans during the first ninethree months of 2017.2020.
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 unaudited consolidated balance sheets.
Accrual of interest on loans generally is discontinued when contractual payment of principal or interest becomes past due 90 days or, if in management's judgment, reasonable doubt exists as to the full timely collection of interest. Prior to the adoption of ASC 326, loans categorized as ASC 310-30 accrued regardless of past due status. 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 or reasonably expects to make 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 September 30, 2017,March 31, 2020, the Company had nonperforming assets of $44.4$41.1 million, representing 0.66%0.49% of total assets, compared to nonperforming assets of $41.5$22.1 million, or 0.64%0.28% of total assets as of December 31, 2016.2019. The increase in nonperforming assets was primarily due to an increasedriven by the inclusion of $2.6$9.7 million of ASC 310-30 loans previously categorized in OREO, as well as an increasenonperforming assets and one commercial relationship of $0.4$8.5 million that was placed on nonaccrual status, partially offset by a decrease in other repossessed assets during the first ninethree months of 2017.

2020.
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, management believes it is likely that the level of nonperforming assets would increase, as would the level of charged-off loans.        

Past Due and Accruing
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. Prior to the adoption of ASC 326, loans categorized as ASC 310-30 accrued 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 when principal and interest payments are current, full collectability of principal and interest is reasonably assured and a consistent record of at least six6 consecutive months of performance has been achieved.
As of September 30, 2017,March 31, 2020, the Company had loans and leases greater than 90 days past due and accruing of $2.5$1.0 million, or 0.04%0.02% of total loans and leases, compared to $7.1$10.1 million, or 0.13%0.15% of total loans and leases, as of December 31, 2016,2019, representing ana decrease of $4.6$9.1 million. The decrease in past due and accruing loans was primarily due to the payoffs$9.1 million of several past due and accruing acquired loans during the first nine months of 2017.previously accounted for under ASC 310-30, which are now disclosed as being on non-accrual status.

Troubled Debt RestructuredRestructuring Loans and Leases
Total TDR loans decreased by $0.9 million to $22.3 million at March 31, 2020 from $23.2 million at December 31, 2019. The decrease primarily resulted from the payments of TDR loans during the first three months of 2020.
As of September 30, 2017, restructuredMarch 31, 2020, total TDR loans included $5.0 million of commercial real estate loans, $0.8 million of multi-family mortgage loans, $17.3$9.6 million of commercial loans, $3.9$5.1 million of equipment financing loans and leases, $1.1$2.2 million of residential mortgage loans, and $1.2$2.0 million of home equity loans. As of December 31, 2016, restructured loans, included $4.9$1.7 million of commercial real estate loans, $2.0$1.5 million of construction loans, and $0.1 million of multi-family mortgage loans. As of December 31, 2019, total TDR loans $13.7included $9.0 million of commercial loans, $2.1$5.6 million of equipment financing loans and leases, $1.3$2.1 million of residential mortgage loans, and $1.8$1.9 million of home equity loans, $1.7 million of commercial real estate loans, $2.9 million of construction loans and $0.1 million of multi-family mortgage loans. A restructuredTDR loan is a loan for which the maturity date was extended, the principal was reduced, and/or the interest rate was modified to drop the required monthly payment to a more manageable amount for the borrower.

Allowances for Credit Losses
The allowance for loan and leasecredit losses consists of general and specific allowances and reflects management's estimate of probableexpected 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 leasecredit losses on a quarterly basis. The allowance is calculated by loan type: commercial real estate loans, commercial loans and leases, and consumer loans, each category of which is further segregated. A formula-based credit evaluation approach is applied to each group that is evaluated collectively, primarily by loss factors, which includes estimates of incurred losses over an estimated LEP, assigned to each risk rating by type, coupled with an analysis of certain loans individually evaluated for impairment. Management continuously evaluates and challenges inputs and assumptions in the allowance for loan and lease loss.credit losses.
The process to determine the allowance for loan and lease losses requires management to exercise considerable judgment regarding the risk characteristics of the loan portfolios and the effect of relevant internal and external factors. While management evaluates currently available information in establishing the allowance for loan and leasecredit 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 leasecredit 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 leasecredit losses and carrying amounts of other real estate owned. Such agencies may require the financial institution to recognize additions to the allowance based on their judgments about information available to them at the time of their examination.
The Company’s general allowance methodology provides a quantification of probable losses in the portfolio. Under the current methodology, Management combinesmanagement estimates losses over the historical loss informationlife of the Banksloan using reasonable and supportable forecasts. Forecasts, loan data, and model documentation is extensively analyzed and reviewed throughout the quarter to generate a single set of ratios.

Management believes it is appropriate to aggregate the ratios as the Banks share common environmental factors, operate in similar markets, and utilize common underwriting standards in accordance with the Company's Credit Policy.
Management employs a similar analysis for the consolidation of the qualitative factors as it does for the quantitative factors. Again, Management believes the combination of the existing nine qualitative factors usedensure estimated losses are accurate 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.
As of September 30, 2017, the Company had a portfolio of approximately $27.1 million in loans secured by taxi medallions issued by the cities of Boston and Cambridge. As of December 31, 2016, this portfolio was approximately $31.1 million. Application-based mobile ride services, such as Uber and Lyft, have generated increased competition in the transportation sector, resulting in a reduction in taxi utilization and, as a result, a reduction in the collateral value and credit quality of taxi medallion loans. This has increased the likelihood that loans secured by taxi medallions may default, or that the borrowers may be unable to repay these loans at maturity, potentially resulting in an increase in past due loans, troubled debt restructurings, and charge-offs. The Company’s allowance calculation included a further segmentation of the commercial loans and leases to reflect the increased risk in the Company’s taxi medallion portfolio. This allowance calculation segmentation represents management’s estimations of the risks associated with the portfolio.quarter end.
The following tables present the changes in the allowance for loan and lease losses by portfolio category for the three and nine months ended September 30, 2017March 31, 2020 and 2016.

At March 31, 2020, the allowance for loan and lease losses increased to $113.2 million, or 1.16%1.66% of total loans and leases outstanding.outstanding, as a result of the latest available forecast of economic effect of the COVID-19 pandemic on the Company's loan and lease portfolios.

The $10.2 million increase in the allowance for commercial loans and lease losses during 2017 was primarily due to the increase in specific reserves for taxi medallion loans as a result of a change in the underlying collateral value, the increase in the specific reserve of a number of commercial loans, the increase in historical loss factors applied to commercial loan portfolios including taxi medallion portfolio in the first nine months of 2017, and the originated loan growth of 96.3 million, or 6.5% from December 31, 2016.

The $0.5 million increase in the allowance for consumer loans during the first nine months of 2017 was primarily driven by the increase in the historical loss factors applied to the consumer portfolios and the originated loan growth of $58.3 million, or 6.8%, from December 31, 2016. The ratio of originated consumer loans on nonaccrual to total originated consumer loans increased to 0.23% as of September 30, 2017 from 0.30% as of December 31, 2016. The risk of loss on a home equity loan is higher since the property securing the loan has often been previously pledged as collateral for a first mortgage loan. The Company gathers and analyzes delinquency data, to the extent that data are available on these first liens, for purposes of assessing the collectability of the second liens held by the Company even if these home equity loans are not delinquent. This data are further analyzed for performance differences between amortizing and non-amortizing home equity loans, the percentage borrowed to total loan commitment and by the amount of payments made by the borrowers. The loss exposure is not considered to be high due to the combination of current property values, the historically low loan-to-value ratios, the low level of losses experienced in the past few years and the low level of loan delinquencies as of September 30, 2017. If the local economy weakens, however, a rise in losses in those loan classes could occur. Historically, losses in these classes have been low.
Net charge-offs in the consumer loan portfolio for the three months ended September 30, 2017 and September 30, 2016 were $33.0 thousand and $95.0 thousand, respectively. Provisions for consumer loans recorded in these periods more than adequately covered charge-offs during those periods.
Net charge-offs in the consumer loan portfolio for the nine months ended September 30, 2017 and September 30, 2016 were $66.0 thousand and $649.0 thousand, respectively. Provisions for consumer loans recorded in these periods more than adequately covered charge-offs during those periods.

The fair value of investment securities is based principally on market prices and dealer quotes received from third-party, nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. The Company's marketable equity securities are priced this way and are included in Level 1.1 of the fair value hierarchy in accordance with ASC 820. These prices are validated by comparing the primary pricing source with an alternative pricing source when available. When quoted market prices for identical securities are unavailable, the Company uses market prices provided by independent pricing services based on recent trading activity and other observable information, including but not limited to market interest-rate curves, referenced credit spreads and estimated prepayment speeds where applicable. These investments include certain U.S. and government agency debt securities, municipal and corporate debt securities, GSE residential MBSs and CMOs, and trust preferred securities, all of which are included in Level 2 and equity securities held-for-trading, which are included in Level 1 and Level 2. Certain fair values are estimated using pricing models and are included in Level 3.


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

As of September 30, 2017,December 31, 2019, the fair value of all investment securities held-to-maturity was $107.2 million and carried a total of $0.5 million of net unrealized losses, compared to a fair value of $85.3$87.6 million and net unrealized lossesgains of $1.8 million as$0.8 million.

This compares to $82.0 million, or 96.1%, of the portfolio with gross unrealized losses of $1.9 million as of December 31, 2016. The Company's unrealized loss position decreased in 2017 driven by lower long-term interest rates.
Management believes that these negative differences between amortized cost and fair value do not include credit losses, but rather differences in interest rates between the time of purchase and the time of measurement. It is more likely than not that the Company will not sell or be required to sell the investment securities before recovery, and, as a result, it will recover the amortized cost basis of the investment securities. As such, management has determined that the securities are not other-than-temporarily impaired as of September 30, 2017. If market conditions for securities worsen or the creditworthiness of the underlying issuers deteriorates, it is possible that the Company may recognize additional other-than-temporary impairments in future periods. For additional discussion on how the Company validates fair values provided by the third-party pricing service, see Note 11, “Fair Value of Financial Instruments.”

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

FHLBB borrowings decreasedincreased by $38.3$379.0 million to $872.6 million$1.1 billion as of September 30, 2017March 31, 2020 from the December 31, 20162019 balance of $910.8$758.5 million.

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

components of interest income and interest expense, expressed in terms of fluctuation in average volume and rate, are summarized under "Rate/Volume Analysis" below. Information as to the components of interest income, interest expense and average rates is provided under "Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin" below.
Because the Company's assets and liabilities are not identical in duration and in repricing dates, the differential between the two is vulnerable to changes in market interest rates as well as the overall shape of the yield curve. These vulnerabilities are inherent to the business of banking and are commonly referred to as "interest-rate risk." How interest-rate risk is measured and, once measured, how much interest-rate risk is taken on, are based on numerous assumptions and other subjective judgments. See the discussion in “Item 3. Quantitative and Qualitative Disclosures about Market Risk” below.
The quality of the Company's assets also influences its earnings. Loans and leases that are not paid on a timely basis and exhibit other weaknesses can result in the loss of principal and/or interest income. Additionally, the Company must make timely provisions to the allowance for loan and lease losses based on estimates of probable losses inherent in the loan and lease portfolio. These additions, which are charged against earnings, are necessarily greater when greater probable losses are expected. Further, the Company incurs expenses as a result of resolving troubled assets. These variables reflect the "credit risk" that the Company takes on in the ordinary course of business and are further discussed under "Financial Condition—Asset Quality" above.
Net Interest Income
Net interest income increased $4.4decreased $1.3 million to $56.8$61.7 million for the three months ended September 30, 2017March 31, 2020 from $52.4$63.0 million for the three months ended September 30, 2016.March 31, 2019. This overall increasedecrease reflects a $5.2$1.1 million increasedecrease in interest income on loans and leases and a $0.3$0.5 million increasedecrease in interest income on investment securities, partially offset by a $1.2$0.3 million increasedecrease in interest expense on deposit and borrowings, which is reflective of the various portfolios repricing and replacing balances into the current interest rate environment. Refer to “Results of Operations - Comparison of the Three-Month Period Ended September 30, 2017

Net interest income increased $13.7 million to $165.5 million for the nine months ended September 30, 2017 from $151.8 million for the nine months ended September 30, 2016. This overall increase reflects a $15.3 million increase in interest income on loans and leases and a $0.6 million increase in interest income on investment securities, offset by a $2.3 million increase in interest expense on deposit and borrowings, which is reflective of the various portfolios repricing and replacing balances into the current interest rate environment. Refer to “Results of Operations - Comparison of the Nine-Month Period Ended September 30, 2017 and September 30, 2016 — Interest Income” and “Results of Operations - Comparison of the Nine-Month Period Ended September 30, 2017 and September 30, 2016 — Interest Expense Deposit and Borrowed Funds” below for more details.

Management 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 have also increased. During the first quarter of 2020 interest rates declined sharply in response to the economic impact of the COVID-19 pandemic. 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 net interest income, net interest spread, and the net 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:Due to, among other things, ongoing pricing pressures in both the loan and deposit portfolios, the ability to increase the Company's core deposits, decrease its loan-to-deposit ratio, and decrease its reliance on FHLBB advances. Netnet interest income may also be negatively affected by changes in the amount of accretion on acquired loans and leases, deposits and borrowed funds, which areis included in interest income and interest expense, respectively.

Average Balances, Net Interest Income, Interest-Rate Spread and Net Interest Margin
The following table sets forth information about the Company's average balances, interest income and interest rates earned on average interest-earning assets, interest expense and interest rates paid on average interest-bearing liabilities, interest-rate spread and net interest margin for the three and nine months ended September 30, 2017March 31, 2020 and September 30, 2016.March 31, 2019. Average balances are derived from daily average balances and yields include fees, costs and purchase-accounting-related premiums and discounts which are considered adjustments to coupon yields in accordance with GAAP. Certain amounts previously reported have been reclassified to conform to the current presentation.

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.

The decrease in the effective tax rates for the three and nine months ended September 30, 2017 was due to the adoption of ASU 2016-09. This ASU requires that the excess tax benefit associated with stock compensation transactions be recorded through earnings as a discrete item within the Company's effective tax rate during the period of the transaction. The prior guidance required the recognition of the excess tax benefit through additional paid in capital. The majority of the Company's stock based compensation events occur in the third quarter. Refer also to Note 9, "Stock Based Compensation."
During the third quarter of 2017, the Company was notified by the Internal Revenue Service (IRS) of its intent to examine the Company's 2015 consolidated federal income tax return. Management believes that this examination will conclude during the next 12 months.
Liquidity and Capital Resources
Liquidity
Liquidity is defined as the ability to meet current and future financial obligations of a short-term nature. The Company further defines liquidity as the ability to respond to the needs of depositors and borrowers, as well as to earnings enhancement opportunities, in a changing marketplace. Liquidity management is monitored by an Asset/Liability Committee ("ALCO"), consisting of members of management, which is responsible for establishing and monitoring liquidity targets as well as strategies and tactics to meet these targets.
The primary source of funds for the payment of dividends and expenses by the Company is dividends paid to it by the Banks and Brookline Securities Corp. The primary sources of liquidity for the Banks consist of deposit inflows, loan repayments, borrowed funds, and maturing investment securities.
Management has reacted strategically to the COVID-19 pandemic and enhanced the liquidity positioning of the Company's balance sheet. The Company continues to execute on a contingent liquidity plan for a severely adverse operating environment. The most visible result of this plan is an increase to balance sheet liquidity in the form of excess cash and highly liquid securities. This increase of cash and securities is to meet customer borrowing needs, serve for unexpected deposit outflows and provide a buffer against a disruption in cash flows due to deferred payments of principal and interest from the loan portfolio.

Management has strategically enhanced the amount of balance sheet liquidity in the form of cash and investment securities available for sale since the start of the COVID-19 pandemic crisis. Cash and equivalents at the end of the quarter were $340.8 million, or 4.0% of the balance sheet, this compares to $77.8 million, or 1.0% of the balance sheet, as of December 31, 2019. Management also restructured the composition of the investment portfolio which resulted in an increase in highly liquid securities of $175.0 million quarter over quarter. In general, during a normal operating environment, the Company seeks to maintain liquidity and targets cash, cash equivalents and investment securities available-for-sale balances of between 5% and 10% of total assets. Due to the nature of the current challenging operating environment, that target operating range is between 10% and 15%. As of March 31, 2020, cash, cash equivalents and investment securities available-for-sale totaled $1.1 billion, or 13.0% of total assets. This compares to $576.8 million, or 7.3% of total assets, as of December 31, 2019.
Deposits, which are considered the most stable source of liquidity, totaled $4.8$5.9 billion as of September 30, 2017March 31, 2020 and represented 83.0%82.0% of total funding (the sum of total deposits and total borrowings), compared to deposits of $4.6$5.8 billion, or 81.5%86.6% of total funding, as of December 31, 2016.2019. Core deposits, which consist of demand checking, NOW, savings and money market accounts, totaled $3.6$3.9 billion as of September 30, 2017March 31, 2020 and represented 75.7%65.6% of total deposits, compared to core deposits of $3.6$3.8 billion, or 77.4%65.3% of total deposits, as of December 31, 2016.2019. Additionally, the Company had $260.8$354.1 million of brokered deposits as of September 30, 2017,March 31, 2020, which represented 5.4%6.0% of total deposits, compared to $203.4$349.9 million or 4.4%6.0% of total deposits, as of December 31, 2016.2019. The Company offers attractive interest rates based on market conditions to increase deposits balances, while managing cost of funds.
Borrowings are used to diversify the Company's funding mix and to support asset growth. When profitable lending and investment opportunities exist, access to borrowings provides a means to grow the balance sheet. Borrowings totaled $1.0$1.3 billion as of September 30, 2017,March 31, 2020, representing 17.0%18.0% of total funding, compared to $1.0 billion,$902.7 million, or 18.5%13.4% of total funding, as of December 31, 2016.2019.
As members of the FHLBB, the Banks have access to both short- and long-term borrowings. As of September 30, 2017 and DecemberMarch 31, 2016,2020, the Company's total borrowing limit from the FHLBB for advances and repurchase agreements was $1.5$2.1 billion, compared to $2.1 billion as of December 31, 2019, based on the level of qualifying collateral available for these borrowings.

As of September 30, 2017,March 31, 2020, the Banks also have access to funding through certain uncommitted lines of credit of $204.0$568.0 million.
The Company had a $12.0 million committed line of credit for contingent liquidity as of September 30, 2017.March 31, 2020. As of September 30, 2017,March 31, 2020, the Company did not have anyhad $5 million outstanding of borrowings on this committed line of credit outstanding.
The Company has access to the Federal Reserve Bank of Boston's "discount window" to supplement its liquidity. The Company has $86.9$109.0 million of borrowing capacity at the Federal Reserve Bank as of September 30, 2017.March 31, 2020. As of September 30, 2017,March 31, 2020, the Company did not have any outstanding borrowings with the Federal Reserve Bank outstanding.Bank.
Additionally, the Banks have access to liquidity through repurchase agreements and additional untapped brokered deposits.
In general, the Company seeks to maintain a high degree of liquidity and targets cash, cash equivalents and investment securities available-for-sale balances of between 10% and 30% of total assets. As of September 30, 2017, cash, cash equivalents and investment securities available-for-sale totaled $586.3 million, or 8.8% of total assets. This compares to $591.3 million, or 9.2% of total assets as of December 31, 2016.
While management believes that the Company has adequate liquidity to meet its commitments and to fund the Banks' lending and investment activities, the availabilities of these funding sources are subject to broad economic conditions and could be restricted in the future. Such restrictions would impact the Company's immediate liquidity and/or additional liquidity needs.
Off-Balance-Sheet Financial Instruments


The Company is party to off-balance-sheet financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include loan commitments, standby and commercial letters of credit and interest-rate swaps. According to GAAP, these financial instruments are not recorded in the financial statements until they are funded or related fees are incurred or received.
 
The contract amounts reflect the extent of the involvement the Company has in particular classes of these instruments. Such commitments involve, to varying degrees, elements of credit risk and interest-rate risk in excess of the amount recognized in the consolidated balance sheet. The Company’s exposure to credit loss in the event of non-performance by the counterparty is represented by the contractual amount of the instruments. The Company uses the same policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Market Risk
Market risk is the risk that the market value or estimated fair value of the Company's assets, liabilities, and derivative financial instruments will decline as a result of changes in interest rates or financial market volatility, or that the Company's net income will be significantly reduced by interest-rate changes.
Interest-Rate Risk
The principal market risk facing the Company is interest-rate risk, which can occur in a variety of forms, including repricing risk, yield-curve risk, basis risk, and prepayment risk. Repricing risk occurs when the change in the average yield of either interest-earning assets or interest-bearing liabilities is more sensitive than the other to changes in market interest rates. Such a change in sensitivity could reflect a number of possible mismatches in the repricing opportunities of the Company's assets and liabilities. Yield-curve risk reflects the possibility that changes in the shape of the yield curve could have different effects on the Company's assets and liabilities. Basis risk occurs when different parts of the balance sheet are subject to varying base rates reflecting the possibility that the spread from those base rates will deviate. Prepayment risk is associated with financial instruments with an option to prepay before the stated maturity, often a disadvantage to person selling the option; this risk is most often associated with the prepayment of loans, callable investments, and callable borrowings.
Asset/Liability Management
Market risk and interest-rate risk management is governed by the Company's Asset/Liability Committee ("ALCO").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 tointo 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 September 30, 2017March 31, 2020 or December 31, 2016.2019. See Note 8, “Derivatives and Hedging Activities,” to the unaudited consolidated financial statements.
Measuring Interest-Rate Risk
As noted above, interest-rate risk can be measured by analyzing the extent to which the repricing of assets and liabilities are mismatched to create an interest-rate sensitivity gap. An asset or liability is said to be interest-rate sensitive within a specific period if it will mature or reprice within that period. The interest-rate sensitivity gap is defined as the difference between the amount of interest-earning assets maturing or repricing within a specific time period and the amount of interest-bearing liabilities maturing or repricing within that same time period. A gap is considered positive when the amount of interest-rate-sensitive assets exceeds the amount of interest-rate-sensitive liabilities. A gap is considered negative when the amount of interest-rate-sensitive liabilities exceeds the amount of interest-rate-sensitive assets. During a period of falling interest rates, therefore, a positive gap would tend to adversely affect net interest income. Conversely, during a period of rising interest rates, a positive gap position would tend to result in an increase in net interest income.
The Company's interest-rate risk position is measured using both income simulation and interest-rate sensitivity "gap" analysis. Income simulation is the primary tool for measuring the interest-rate risk inherent in the Company's balance sheet at a given point in time by showing the effect on net interest income, over a twelve-month period, of a variety of interest-rate shocks. These simulations take into account repricing, maturity, and prepayment characteristics of individual products. The ALCO reviews simulation results to determine whether exposure resulting from changes in market interest rates remains within

established tolerance levels over a twelve-month horizon, and develops appropriate strategies to manage this exposure. The Company's interest-rate risk analysis remains modestly asset-sensitive as of September 30, 2017.March 31, 2020.

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 September 30, 2017,March 31, 2020, 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 point increase in market interest rates on the Company's estimated net interest income over a twelve-month horizon was a positive 4.9%14.3% as of September 30, 2017,March 31, 2020, compared to a positive 3.0%11.5% as of December 31, 2016, the2019. The increase in asset sensitivity was due to a changean increase in the funding mix, as core deposits and issued common stock funded balance sheet growth.

short term liquidity positions.
The Company also uses interest-rate sensitivity “gap” analysis to provide a more general overview of its interest-rate risk profile. The interest-rate sensitivity gap is defined as the difference between interest-earning assets and interest-bearing
liabilities maturing or repricing within a given time period. At September 30, 2017,March 31, 2020, the Company’s one-year cumulative gap was a negative $55.6$73.2 million, or 0.9%0.93% of total interest-earning assets, compared with a negative $275.3positive $4.7 million, or 4.56%0.06% of total interest-earning assets, at December 31, 2016.
2019.
The assumptions used in the Company's interest-rate sensitivity simulation discussed above are inherently uncertain and, as a result, the simulations cannot precisely measure net interest income or precisely predict the impact of changes in interest rates. For additional discussion on interest-rate risk see Item 7A, “Quantitative and Qualitative Disclosures about Market Risk” of the Company’s 20162019 Annual Report on Form 10-K.

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

EVE at Risk is calculated by estimating the net present value of all future cash flows from existing assets and liabilities using current interest rates as well as parallel shocks to the current interest-rate environment. The following table sets forth the estimated percentage change in the Company’s EVE at Risk, assuming various shifts in interest rates. Given the interest rate environment as of September 30, 2017,March 31, 2020, simulations for interest rate declines of more than 100 basis points were not deemed to be meaningful.

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 considered that, as of the end of the period covered by this report, the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is (i) recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to the Company’s Management,management, including its Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
 
There has beenEffective January 1, 2020, the Company adopted ASU 2016-13. The Company implemented changes to its policies, processes, and controls over the allowance for credit losses methodology to support the adoption of ASU 2016-13. Many controls over this new accounting methodology mirror controls under the prior GAAP methodology. New controls were established, such as model validation done by an independent third-party and input review of econometric and other factors utilized in estimating the allowance. Except as related to the adoption of ASU 2016-13, there were no changechanges in the Company’s internal control over financial reporting identified in connection with the quarterly evaluation that occurred during the Company’s last fiscal quarter that has materially and detrimentally affected, or is reasonably likely to materially and detrimentally affect, the Company’s internal controls over financial reporting during the quarter ended March 31, 2020 that have materially affected, or are reasonably likely to materially affect, our 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.
