BROOKLINE BANCORP, INC. AND SUBSIDIARIES

Notes to Unaudited Consolidated Financial Statements
(1) Basis of Presentation
Overview
Brookline Bancorp, Inc. (the "Company") is a bank holding company (within the meaning of the Bank Holding Company Act of 1956, as amended) and the parent of Brookline Bank, a Massachusetts-chartered trust company and Bank Rhode Island ("BankRI"), a Rhode Island-chartered financial institution (collectively referred to as the "Banks"). The Banks are both members of the Federal Reserve System. The Company is also the parent of Brookline Securities Corp. ("BSC"). The Company's primary business is to provide commercial, business and retail banking services to its corporate, municipal and retail customers through the Banks and its non-bank subsidiaries. Until February 15, 2020 (the "Merger Closing Date"), the Company was also the parent of First Ipswich Bank ("First Ipswich"), a Massachusetts-chartered trust company. Effective upon the Merger Closing Date, First Ipswich was merged with and into Brookline Bank, with Brookline as the surviving institution.
Brookline Bank, which includes its wholly-owned subsidiaries Longwood Securities Corp. ("LSC"), Eastern Funding LLC ("Eastern Funding") and First Ipswich Insurance Agency, operates 30 full-service banking offices in the greater Boston metropolitan area with 2 additional lending offices. As of July 21, 2020, BBS Investment Corp. and First Ipswich Securities II Corp were merged with and into LSC. BankRI, which includes its wholly-owned subsidiaries, Acorn Insurance Agency, BRI Realty Corp., Macrolease Corporation ("Macrolease"), BRI Investment Corp. and its wholly-owned subsidiary, BRI MSC Corp., operates 20 full-service banking offices in the greater Providence, Rhode Island area.
The Banks' activities include acceptance of commercial, municipal and retail deposits, origination of mortgage loans on commercial and residential real estate located principally in New England, origination of commercial loans and leases to small- and mid-sized businesses, investment in debt and equity securities, and the offering of cash management and investment advisory services. Brookline Bank also provides specialty equipment financing through its subsidiaries Eastern Funding, which is based in New York City, New York, and Macrolease, which is based in Plainview, New York.
The Company and the Banks are supervised, examined and regulated by the Board of Governors of the Federal Reserve System (the "FRB"). As a Massachusetts-chartered trust company, Brookline Bank is also subject to regulation under the laws of the Commonwealth of Massachusetts and the jurisdiction of the Massachusetts Division of Banks (the "DOB"). As a Rhode Island-chartered financial institution, BankRI is subject to regulation under the laws of the State of Rhode Island and the jurisdiction of the Banking Division of the Rhode Island Department of Business Regulation.
The Federal Deposit Insurance Corporation ("FDIC") offers insurance coverage on all deposits up to $250,000 per depositor at each of the Banks. As FDIC-insured depository institutions, the Banks are also subject to supervision, examination and regulation by the FDIC. As previously disclosed on a Form 8-K filed with the Securities and Exchange Commission ("SEC"), on July 31, 2019, Brookline Bank ended its membership in the Depositors Insurance Fund (“DIF”), a private industry-sponsored fund which insures Massachusetts-chartered savings bank deposit balances in excess of federal deposit insurance coverage. Brookline Bank’s growth in deposit size necessitated its withdrawal from the DIF and the concurrent charter conversion of Brookline Bank from a Massachusetts-chartered savings bank to a Massachusetts-chartered trust company.
Basis of Financial Statement Presentation
The unaudited consolidated financial statements of the Company presented herein have been prepared pursuant to the rules of the SEC for quarterly reports on Form 10-Q and do not include all of the information and note disclosures required by U.S. generally accepted accounting principles (“GAAP”). In the opinion of management, all adjustments (consisting of normal recurring adjustments) and disclosures considered necessary for the fair presentation of the accompanying consolidated financial statements have been included. Interim results are not necessarily reflective of the results of the entire year. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2019. 
The unaudited consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances are eliminated in consolidation.
In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events. Material estimates that are particularly susceptible to significant changes in the near-term include the

determination of the allowance for credit losses, the determination of fair market values of assets and liabilities, the review of goodwill and intangible assets for impairment and the review of deferred tax assets for valuation allowances.
The judgments used by management in applying these critical accounting policies may be affected by a further and prolonged deterioration in the economic environment, which may result in changes to future financial results. For example, subsequent evaluations of the loan and lease portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for loan and lease losses in future periods, and the inability to collect outstanding principal may result in increased loan and lease losses.
Reclassification
Certain previously reported amounts have been reclassified to conform to the current year's presentation.
Recent Accounting Pronouncements
Accounting Standards Adopted in 2020
In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of 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 lifetime expected 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 a decrease to retained earnings of $11.5 million shown in the Consolidated Statements of Changes in Stockholders’ Equity. Additional details can be found in Notes 3, 4 and 5.
In August 2018, FASB issued ASU 2018-13, "Fair Value Measurement (Topic 820)" ("ASU 2018-13"), to modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement, based on the concepts set forth in the Concepts Statement, including the consideration of costs and benefits. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Certain provisions under ASU 2018-13 required prospective application, while other provisions required retrospective application to all periods presented in the consolidated financial statements upon adoption. The Company 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.
(2) Acquisitions and Mergers
First Ipswich Bank
On February 15, 2020, the merger of First Ipswich Bank with and into Brookline Bank was completed. First Ipswich was already a wholly-owned subsidiary of the Company, therefore the merger qualified as a tax-free reorganization for federal income tax purposes and there was minimal impact to customers. All of First Ipswich Bank's six branch locations were retained and converted to Brookline Bank branches.

(3) Investment Securities
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 credit loss ("ACL") on available-for-sale debt securities recognized upon adoption and as of March 31, 2020.

COVID-19 pandemic. As of December 31, 2019, the fair value of investment securities held-to-maturity was $87.6 million with net unrealized gains of $0.8 million. As of December 31, 2019, $22.3 million, or 25.5% of the portfolio had gross unrealized losses of $0.2 million.
As of September 30, 2020, the Company recorded a fair value of $0.5 million of equity securities held-for-trading. As of December 31, 2019, the Company recorded a fair value of $3.6 million of equity securities held-for-trading.
Investment Securities as Collateral
As of September 30, 2020 and December 31, 2019, respectively, $458.5 million and $433.6 million of investment securities were pledged as collateral for repurchase agreements; municipal deposits; treasury, tax and loan deposits; swap agreements; FRB borrowings; and Federal Home Loan Bank of Boston ("FHLBB") borrowings. The Banks had no outstanding FRB borrowings as of September 30, 2020 and December 31, 2019.
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 $2.7 million and $2.0 million, respectively, as of September 30, 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 September 30, 2020 and 2019.
Assessment for Available for Sale Securities for Impairment
Investment securities as of September 30, 2020 and December 31, 2019 that have been in a continuous unrealized loss position for less than twelve months or twelve months or longer are as follows:

The Company performs regular analyses of the investment securities available-for-sale portfolio to determine whether a decline in fair value indicates that an investment security is impaired. In making these impairment determinations, management considers, among other factors, projected future cash flows; credit subordination and the creditworthiness; capital adequacy and near-term prospects of the issuers.
Management also considers the Company's capital adequacy, interest-rate risk, liquidity and business plans in assessing whether it is more likely than not that the Company will sell or be required to sell the investment securities before recovery. If the Company determines that a decline in fair value is impairment 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 impairment represents the difference between the
12

Notes to Unaudited Consolidated Financial Statements (Continued)
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 impairment 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 impaired as of September 30, 2020. Based on the analysis below, it was determined that is it 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 impaired as of September 30, 2020. If market conditions for investment securities worsen or the creditworthiness of the underlying issuers deteriorates, it is possible that the Company may recognize additional impairment in future periods.
U.S. Government-Sponsored Enterprises
The Company invests in securities issued by U.S. Government-sponsored enterprises ("GSEs"), including GSE debentures, mortgage-backed securities ("MBSs"), and collateralized mortgage obligations ("CMOs").

performing and backed by the explicit guarantee of the U.S Government. During the nine months ended September 30, 2020 and 2019, the Company did not purchase any SBA securities.
Corporate Obligations
The Company may invest in high-quality corporate obligations to provide portfolio diversification and improve the overall yield on the portfolio. As of September 30, 2020, the Company held 6 corporate obligation securities with a total fair value of $23.5 million and a net unrealized gain of $1.2 million. As of December 31, 2019, the Company held 8 corporate obligation securities with a total fair value of $29.0 million and a net unrealized gain of $0.5 million. As of September 30, 2020 and December 31, 2019, none of the securities in this portfolio were in an unrealized loss position. Full collection of the obligations is expected because the financial condition of the issuers is sound, they have not defaulted on scheduled payments, the obligations are rated investment grade, and the Company has the ability and intent to hold the obligations for a period of time to recover the amortized cost. During the nine months ended September 30, 2020 and 2019, the Company did not purchase any corporate obligations.

Actual maturities of debt securities will differ from those presented above since certain obligations amortize and may also provide the issuer the right to call or prepay the obligation prior to scheduled maturity without penalty. MBSs and CMOs are included above based on their final stated maturities; the actual maturities, however, may occur earlier due to anticipated prepayments and stated amortization of cash flows.
As of September 30, 2020, issuers of debt securities with an estimated fair value of $91.7 million had the right to call or prepay the obligations. Of the $91.7 million, approximately $13.5 million matures in 1 - 5 years, $68.3 million matures in 6 - 10 years, and $9.9 million matures after ten years. As of December 31, 2019, issuers of debt securities with an estimated fair value of approximately $37.6 million had the right to call or prepay the obligations. Of the $37.6 million, approximately $3.0 million matures within 1 year, $34.6 million matures in 1-5 years, and none mature after 5 years.

The net unamortized deferred loan origination costs included in total loans and leases were $0.4 million and $15.7 million as of September 30, 2020 and December 31, 2019, respectively. The decrease in net unamortized deferred loan origination costs and (fees) was primarily due to the net unamortized deferred origination fees of $(13.3) million for the SBA's Payment Protection Program ("PPP") loans which were originated during the second quarter of 2020.
The Banks and their subsidiaries lend primarily in all New England states, with the exception of equipment financing, 28.0% of which is in the greater New York and New Jersey metropolitan area and 72.0% of which is in other areas in the United States of America as of September 30, 2020.
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 September 30, 2020, there were no PCD loans in the Company's portfolios.
The following table summarizes activity in the accretable yield for the acquired loan portfolio for the periods indicated:

The allowance for credit losses for unfunded credit commitments, which is included in other liabilities, was $14.0 million and $1.9 million at September 30, 2020 and December 31, 2019, respectively. The increase in allowance for unfunded commitments was primarily driven by the adoption of CECL and the effect of the latest available economic forecast which incorporates the impact of the COVID-19 pandemic. No credit commitments were charged off against the liability account in the nine month periods ended September 30, 2020 and 2019.

Allowance for Loan and Lease Losses Methodology
Management has established a methodology to determine the adequacy of the allowance for credit losses that assesses the risks and losses expected on the loan and lease portfolio. Additions to the allowance for credit 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.

Notes to Unaudited Consolidated Financial Statements (Continued)
To calculate the allowance for loans collectively evaluated, management uses models developed by a 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.
Key assumptions used in the models include portfolio segmentation, prepayments, and the expected utilization of unfunded commitments, among others. The portfolios are segmented by loan level attributes such as loan size, date of origination, and delinquency status to create homogenous loan pools. Pool level metrics are calculated and loss rates are subsequently applied to the pools as the loans have like characteristics. Prepayment assumptions are embedded within the models and are based on the same data used for model development. Model development data and developmental time periods vary by model, but all use at least ten years of historical data and capture at least one recessionary period. Expected utilization is based on current utilization and a loan equivalency (LEQ) factor. LEQ varies by current utilization and provides a reasonable estimate of expected draws and borrower behavior. Assumptions and model inputs are reviewed in accordance with model monitoring practices and as information becomes available.
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 Gross Domestic Product ("GDP"), interest rates, property price indices, and employment measures. The forecasts are probability-weighted based on 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 at the input level to predict credit losses for loans that are expected to mature beyond the forecast period. The September 30, 2020 forecasts reflect the immediate and longer-term effects of the COVID-19 pandemic as well as the associated policies and fiscal support 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 due to geography and portfolio as well as variances in operational and underwriting procedures from the Company, and therefore, the Company calibrates expected losses using a scalar for each model. Each scalar was calculated by examining the loss rates of peer banks that have similar operations and asset bases to the Company and comparing these peer group loss rates to the model results. 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 also applied to select segments of the loan portfolio where applicable.
For September 30, 2020, management applied qualitative adjustments to the CRE lifetime loss rate and C&I lifetime loss rate. These adjustments were made based on historical loss patterns, current loan and portfolio metrics, and expert judgment based on professional experience. These qualitative adjustments resulted in additions to reserves for the CRE and C&I portfolio, as compared to the model output.
Specific reserves are established for loans individually evaluated for impairment when amortized cost basis is greater than the discounted present value of expected future cash flows or, in the case of collateral-dependent loans, when there is an excess of a loan's amortized cost basis over the fair value of its underlying collateral. When loans and leases do not share risk characteristics with other financial assets they are evaluated 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 $116.4 million as of September 30, 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, inclusive of the COVID-19 pandemic and legislative initiatives, on the Company's loan and lease portfolios. The specific allowance for loan and lease losses was $3.6 million as of September 30, 2020, compared to $1.8

million as of December 31, 2019. The specific allowance increased by $1.8 million during the nine months ended September 30, 2020 primarily due to the $2.3 million for an individually evaluated commercial real estate relationship, partially off set by the decrease in specific reserves for individually evaluated loans during the nine months ended September 30, 2020.
As of September 30, 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 expected losses over the lifetime of the Company’s loan portfolios.
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, 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 ("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.
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.

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

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 TDR loans. 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 present value of expected future cash flows or, in the case of collateral-dependent loans and leases, any increase in the loan or lease amortized 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.

Total TDR loans and leases decreased by $6.2 million to $17.1 million at September 30, 2020 from $23.2 million at December 31, 2019, driven primarily by the payoffs of one commercial TDR of $3.0 million, one construction TDR of $2.9 million, and payments of current TDR relationships, partially offset by the new TDRs during the nine months ended September 30, 2020.

The TDR loans and leases that were modified for the three months ended September 30, 2020 and 2019 were $1.6 million and $7.7 million, respectively. The decreases in TDR loans and leases that were modified for the three months ended September 30, 2020 were primarily due to the modification of one equipment financing relationship of $1.4 million and one construction relationship of $4.9 million during the three months ended September 30, 2019.
The TDR loans and leases that were modified for the nine months ended September 30, 2020 and 2019 were $3.2 million and $16.0 million, respectively. The decrease in TDR loans and leases that were modified for the nine months ended September 30, 2020 was primarily due to the modification of three commercial relationships totaling $7.1 million and one construction relationship of $4.9 million during the nine months ended September 30, 2019.
The net charge-offs for performing and nonperforming TDR loans and leases for the three and nine months ended September 30, 2020 were $0.2 million and $0.8 million respectively. The net charge-offs for performing and nonperforming TDR loans and leases for the three and nine months ended September 30, 2019 were $0.1 million and $1.9 million respectively.
The commitments to lend funds to debtors owing receivables whose terms had been modified in TDRs as of September 30, 2020 was $1.7 million. As of September 30, 2019, there were $1.4 million commitments to lend funds to debtors owing receivables whose terms had been modified in TDRs.

Notes to Unaudited Consolidated Financial Statements (Continued)
The Coronavirus Aid, Relief and Economic Security ("CARES") Act and regulatory guidance 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 the 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). As of September 30, 2020, the Company granted 5,254 short-term deferments on loan and lease balances of $1.2 billion. Of these modifications, 4,344 loans and leases with total balances of $956.7 million have returned to the payment status and 910 loans and leases with total balances of $279.6 million remain on the deferral status, which represented 3.8% of the Company's total loan and lease balances.

At December 31, 2013, the Company concluded that the BankRI name would continue to be utilized in its marketing strategies; therefore, the trade name with carrying value of $1.1 million, has an indefinite life and ceased to amortize.
The weighted-average amortization period for the core deposit intangible is 6.21 years.

(8) Derivatives and Hedging Activities
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. 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".

The Company believes using interest rate derivatives adds stability to interest income and expense and allows the Company to manage its exposure to interest rate movements. The Company enters into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. The Company enters into interest rate swaps as hedging instruments against the interest rate risk associated with the Company's FHLB borrowings. For derivative instruments that are designated and qualify as cash flow hedging instruments, the effective portion of the gains or losses is reported as a component of other comprehensive income ("OCI"), and is reclassified into earnings in the period that the hedged forecasted transaction affects earnings.
As of September 30, 2020, the Company pays its counterparties a fixed weighted average interest rate of 0.06% over a maximum period of 2 years for derivative instruments that are designated as and qualify as cash flow hedging instruments.
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.
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 present the Company's customer related derivative positions for the periods indicated below for those derivatives not designated as hedging.

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, 2020, the Company had 2 active equity plans: 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 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 15 financial institutions. These are referred to as "performance-based shares". 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 the Plans, shares of the Company's common stock are 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, 2020, 268,936 shares were issued upon satisfaction of required conditions of the Plans. During the three and nine months ended September 30, 2019, 212,460 shares were issued upon satisfaction of required conditions of the Plans.
Total expense for the Plans was $0.7 million and $0.8 million for the three months ended September 30, 2020 and 2019, respectively. Total expense for the Plans was $2.1 million and $2.5 million for the nine months ended September 30, 2020 and 2019, respectively.

Investment Securities Available-for-Sale
The fair value of investment securities is based principally on market prices and dealer quotes received from third-party and nationally-recognized pricing services for identical investment securities such as U.S. Treasury and agency securities. 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, 2020 and December 31, 2019, none of the 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 value of interest rate derivatives designated as hedging instruments, loan level derivatives, risk participation agreements (RPA in/out), and foreign exchange contracts 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

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 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). Using 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.
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.
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 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 credit are conditional commitments issued by the Company to guarantee performance of a customer to a third party. These standby and commercial letters of credit are primarily issued to support the financing needs of the Company's commercial customers. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers.
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 a 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 these derivatives are presented in Footnote 8.

Lease Commitments
The Company leases certain office space under various noncancellable operating leases as well as certain other assets. These leases have original terms ranging from 3 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 September 30, 2020 as the discount rate to determine the net present value of the remaining lease payments.

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.

Notes to Unaudited Consolidated Financial Statements (Continued)
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
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 Company has granted 5,246 short-term deferrals on loan and lease balances of $1.2 billion, which represented 16.5% of total loan and lease balances.
On December 4, 2019, the Board of Directors approved a stock repurchase program authorizing management to repurchase up to $10.0 million of the Company’s common stock over a period of twelve months commencing on January 1, 2020 and ending on December 31, 2020. On March 9, 2020, the Board of Directors approved an increase in the repurchase amount of $10.0 million bringing the total authorized amount to $20.0 million. Subsequently, as previously disclosed, the Company suspended the stock repurchase program effective as of March 24, 2020. As of September 30, 2020, the Company repurchased 848,319 shares at a weighted average price of $12.27. In 2019, 136,065 shares of the Company's common stock were repurchased by the Company. On October 28, 2020, the Company’s Board of Directors approved resumption of the stock repurchase program to be completed by December 31, 2020.

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"); 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 50 full-service banking offices throughout greater Boston, the north shore of Massachusetts and Rhode Island, the Company, through Brookline Bank and 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, 28.0% of which is in the greater New York and New Jersey metropolitan area and 72% of which is in other areas in the United States of America as of September 30, 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, excellent customer service, and strong risk management.
The Company manages the Banks under a uniform strategic 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
54

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. The 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 FRB. A sustained, low interest rate environment with a flat interest rate curve may negatively impact the Company's yields and net interest margin. While the Company is slightly asset sensitive and should benefit from rising rates, changes 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 trust company, Brookline Bank is 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. As previously disclosed, on July 31, 2019, Brookline Bank converted its charter from a Massachusetts savings bank to a Massachusetts-chartered trust company and ended its membership in the Depositors Insurance Fund (“DIF”), a private industry-sponsored fund 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 and 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 were insured by the DIF until July 31, 2020.  Term deposits in excess of the FDIC insurance coverage will continue to be insured by the DIF until they reach maturity.
On March 27, 2020, Congress passed, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted 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. The Company has funded 2,922 PPP loans totaling $581.7 million as of August 8, 2020 when the program closed, of which $568.4 million remains outstanding, net of deferred fees and costs at September 30, 2020. All PPP loans have been funded. PPP loans are fully guaranteed by the U.S. government, have an initial term of up to five years and earn interest at a 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 FRB's Paycheck Protection Program Liquidity Facility ("PPPLF") will extend credit to depository institutions with a term of up to five 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 September 30, 2020, the Company granted 5,254 short-term deferments on loan and lease balances of $1.2 billion. Of these modifications, 4,344 loans and leases with total balances of $956.7 million have returned to the payment status and 910 loans and leases with total balances of $279.6 million remain on the deferral status, which represents 3.8% of the Company's total loan and lease balances. 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.
The Company’s common stock is traded on the Nasdaq Global Select MarketSM under the symbol “BRKL.”

The Company's Tier 1 leverage ratio was 8.67% as of September 30, 2020, compared to 10.28% as of December 31, 2019. As of September 30, 2020, the Company's Tier 1 risk-based capital ratio was 10.91%, compared to 11.58% as of December 31, 2019. The Company's Total risk-based capital ratio was 13.22% as of September 30, 2020, compared to 13.59% as of December 31, 2019.
The Company's ratio of stockholders' equity to total assets was 10.39% and 12.04% as of September 30, 2020 and December 31, 2019, respectively. The Company's tangible equity ratio was 8.73% and 10.15% as of September 30, 2020 and December 31, 2019, respectively.
Net Income
For the three months ended September 30, 2020, the Company reported net income of $18.7 million, or $0.24 per basic and diluted share, a decrease of $3.9 million, or 69.2% on an annualized basis, from $22.6 million, or $0.28 per basic and diluted share for the three months ended September 30, 2019. This decrease in net income is primarily the result of an increase in the provision for credit losses of $3.7 million, a decrease in non-interest income of $3.1 million and an increase in non-interest expense of $0.8 million, partially offset by an increase in net interest income of $2.7 million and a decrease in the provision for income taxes of $0.9 million. Refer to “Results of Operations" below for further discussion.
For the nine months ended September 30, 2020, the Company reported net income of $21.0 million, or $0.27 per basic and diluted share, a decrease of $44.6 million, or 68.0%, from $65.5 million or $0.82 per basic and diluted share for the nine months ended September 30, 2019. This decrease in net income is primarily the result of an increase in the provision for credit losses of $58.0 million, an increase in non-interest expense of $2.1 million and a decrease in non-interest income of $1.6 million, partially offset by a decrease in the provision for income taxes of $14.6 million and an increase in net interest income of $2.6 million. Refer to “Results of Operations" below for further discussion.
The annualized return on average assets was 0.83% for the three months ended September 30, 2020, compared to 1.17% for the three months ended September 30, 2019. The annualized return on average stockholders' equity was 7.99% for the three months ended September 30, 2020, compared to 9.74% for the three months ended September 30, 2019.
The net interest margin was 3.08% for the three months ended September 30, 2020, down from 3.45% for the three months ended September 30, 2019. The decrease in the net interest margin is a result of a decrease in the yield on interest-earning assets of 104 basis points to 3.79% for the three months ended September 30, 2020 from 4.83% for the three months ended September 30, 2019, partially offset by a decrease of 72 basis points in the Company's overall cost of funds to 0.75% for the three months ended September 30, 2020 from 1.47% for the three months ended September 30, 2019.
The net interest margin was 3.15% for the nine months ended September 30, 2020, down from 3.54% for the nine months ended September 30, 2019. The decrease in the net interest margin is a result of a decrease in the yield on interest-earning assets of 81 basis points to 4.04% for the nine months ended September 30, 2020 from 4.85% for the nine months ended September 30, 2019, partially offset by a decrease of 46 basis points in the Company's overall cost of funds to 0.98% for the nine months ended September 30, 2020 from 1.44% for the nine months ended September 30, 2019.
The Company’s net interest margin and net interest income is sensitive to the structure and level of interest rates as well as competitive pricing in all loan and deposit categories.
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 2019 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.

Table of Contents
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. The updates in this standard replace the incurred loss impairment methodology 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 will adopt this ASU for the fiscal year beginning January 1, 2021.
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. 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 a total credit exposure to one obligor relationship may not exceed $50.0 million unless approved by the Company's Credit Committee. As of September 30, 2020, there were 3 borrowers with loans and commitments over $50.0 million. The total of those loans and commitments was $164.0 million, or 1.86% of total loans and commitments, as of September 30, 2020. As of December 31, 2019, there were 3 borrowers with loans and commitments over
64

Table of Contents
$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 51.8% of total loans and leases outstanding as of September 30, 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 ($923.8 million), office buildings ($695.1 million), retail stores ($626.5 million), industrial properties ($453.7 million), mixed-use properties ($323.8 million), lodging services ($151.0 million) and food services ($59.8 million) as of September 30, 2020. At that date, 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.

The Company's commercial loan and lease portfolio is composed primarily of loans to small to medium sized businesses ($636.0 million), transportation services ($382.4 million), food services ($228.9 million), manufacturing ($155.3 million), recreation services ($201.0 million), rental and leasing services ($109.5 million), and retail ($107.2 million) as of September 30, 2020.
The Company provides commercial banking services to companies in its market area. Approximately 55.7% of the commercial loans outstanding as of September 30, 2020 were made to borrowers located in New England. The remaining 44.3% 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 as the SBA 7A program and as an SBA preferred lender. Included in the commercial loans balances are the PPP loans totaling $568.4 million as of September 30, 2020.
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 26.4% of the commercial loans outstanding in the equipment financing divisions 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 3- to 7-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, represented 16.3% of total loans outstanding as of September 30, 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.
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, 2020, other consumer loans equaled $30.2 million, or 0.4% of total loans outstanding.
Asset Quality
Criticized and Classified Assets
The Company's management rates certain loans and leases as "other assets especially mentioned" ("OAEM"), "substandard" or "doubtful" based on criteria established under banking regulations.These loans and leases are collectively referred to as "criticized" assets. Loans and leases rated OAEM have potential weaknesses that deserve management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects of the loan or lease at some future date. Loans and leases rated as substandard are inadequately protected by the payment capacity of the obligor or of the collateral pledged, if any. Substandard loans and leases have a well-defined weakness or weaknesses that jeopardize the liquidation of debt and are characterized by the distinct possibility that the Company will sustain some loss if existing deficiencies are not corrected. 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, 2020, the Company had $83.4 million of total assets that were designated as criticized. This compares to $67.2 million of assets designated as criticized as of December 31, 2019. The increase of $16.2 million in criticized assets was primarily due to three commercial real estate relationships totaling $4.9 million, two commercial loan relationships totaling $8.4 million, and a construction relationship of $3.8 million which became criticized, partially offset by the relationships which were upgraded to pass risk rating during the first nine months of 2020.
Nonperforming Assets
"Nonperforming assets" consist of non-accrual 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 (purchased loans with deteriorating credit quality) 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 non-accrual status, interest accruals cease and uncollected accrued interest is reversed and charged against current interest income. Interest payments on non-accrual 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.
As of September 30, 2020, the Company had nonperforming assets of $39.4 million, representing 0.44% of total assets, compared to nonperforming assets of $22.1 million, or 0.28% of total assets as of December 31, 2019. The increase in nonperforming assets was primarily driven by the inclusion of $9.0 million of ASC 310-30 loans previously categorized in performing assets, one commercial relationship of $4.3 million, and various equipment financing and residential relationships that were placed on non-accrual status, partially offset by the decrease in other repossessed assets during first nine months of 2020.
The Company evaluates the underlying collateral of each non-accrual 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, it is likely that the level of nonperforming assets would increase, as would the level of charged-off loans.        
Past Due and Accruing
As of September 30, 2020, the Company had loans and leases greater than 90 days past due and accruing of $1.2 million, or 0.02% of total loans and leases, compared to $10.1 million, or 0.15% of total loans and leases, as of December 31, 2019, representing a decrease of $8.9 million. The decrease in past due and accruing loans was primarily due to $9.0 million of past due and accruing acquired loans previously accounted for under ASC 310-30, which are now disclosed as being on non-accrual status.

Troubled Debt Restructuring Loans and Leases
Total TDR loans decreased by $6.2 million to $17.1 million at September 30, 2020 from $23.2 million at December 31, 2019. The decrease was driven primarily by the payments and payoffs of the commercial and construction TDRs during the nine months ended September 30, 2020.

Table of Contents
As of September 30, 2020, total TDR loans included $5.3 million of commercial loans, $5.8 million of equipment financing loans and leases, $2.2 million of residential mortgage loans, $2.2 million of home equity loans, and $1.6 million of commercial real estate loans. As of December 31, 2019, total TDR loans included $9.0 million of commercial loans, $5.6 million of equipment financing loans and leases, $2.1 million of residential mortgage loans, $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 TDR 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.

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 pandemic (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. Through September 30, 2020, the Company has granted 5,254 short-term deferments on loan and leases balances of $1.2 billion. Of these modifications, 4,344 loans and leases with total balance of $956.7 million have returned to the payment status and 910 loans and leases with total balance of $279.6 million remain on the deferral status, which represented 3.8% of the Company's total loan and lease balances.
Allowances for Credit Losses
The allowance for credit losses consists of general and specific allowances and reflects management's estimate of expected loan and lease losses over the life of loan or lease. Management uses a consistent and systematic process and methodology to evaluate the adequacy of the allowance for credit losses on a quarterly basis. Management continuously evaluates and challenges inputs and assumptions in the allowance for credit losses.
While management evaluates currently available information in establishing the allowance for credit 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 credit 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 credit losses and carrying amounts of other real estate owned. Such agencies may require the financial institution to recognize additions or reductions to the allowance based on their judgments about information available to them at the time of their examination.
The Company’s allowance methodology provides a quantification of probable losses in the portfolio. Under the current methodology, management estimates losses over the life of the loan using reasonable and supportable forecasts. Forecasts, loan

data, and model documentation are extensively analyzed and reviewed throughout the quarter to ensure estimated losses are accurate at quarter end. Qualitative adjustments are applied when model output does not align with management expectations. These adjustments are thoroughly reviewed and documented to provide clarity and a reasonable basis for any deviations from the model. For September 30, 2020, qualitative adjustments were applied to the CRE and C&I portfolios resulting in a net reduction in total reserves compared to model calculations.

Beginning January 1, 2020, the Company implemented the CECL methodology to calculate the allowance for credit losses. As of January 1, 2020, the Company increased the allowance for loan and lease losses by $6.6 million due to CECL which requires the inclusion of the credit losses over the expected life of the loans, as well as consideration of the risks based on the current conditions and reasonable and supportable forecasts about the future.
At September 30, 2020, the allowance for loan and lease losses increased to $120.0 million, or 1.62% of total loans and leases 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. Excluding PPP loans which are not subject to an allowance reserve since they are guaranteed by the SBA, the allowance for loan and lease losses represents 1.76% of total loans and leases outstanding at September 30, 2020. This compared to an allowance for loan and lease losses of $61.1 million, or 0.91% of total loans and leases outstanding, as of December 31, 2019. Prior to January 1, 2020, the Company calculated the allowance for loan and lease losses using the incurred losses methodology.
Net charge-offs in the loans and leases for the three months ended September 30, 2020 and 2019 were $5.0 million and $0.4 million, respectively. As a percentage of average loans and leases, annualized net charge-offs for the three months ended September 30, 2020 and 2019 were 0.83% and 0.09%, respectively. Net charge-offs in the loans and leases for the nine months ended September 30, 2020 and 2019 were $8.6 million and $5.5 million, respectively. As a percentage of average loans and leases, annualized net charge-offs for the nine months ended September 30, 2020 and 2019 were 0.53% and 0.41%, respectively. The increase in the net charge-off for the three and nine months ended September 30, 2020 was primarily due to the charge-off of $4.3 million on a commercial taxi medallion relationship.
Management believes that the allowance for loan and lease losses as of September 30, 2020 is appropriate.

Investment Securities
The investment portfolio exists primarily for liquidity purposes, and secondarily as a source of interest and dividend income, interest-rate risk management and tax planning as a counterbalance to loan and deposit flows. Investment securities are utilized as part of the Company's asset/liability management and may be sold in response to, or in anticipation of, factors such as changes in market conditions and interest rates, security prepayment rates, deposit outflows, liquidity concentrations and regulatory capital requirements.
The investment policy of the Company, which is reviewed and approved by the Board of Directors on an annual basis, specifies the types of investments that are acceptable, required investment ratings by at least one nationally recognized rating agency, concentration limits and duration guidelines. Compliance with the investment policy is monitored on a regular basis. In general, the Company seeks to maintain a high degree of liquidity and targets cash, cash equivalents and investment securities available-for-sale balances between 10% and 30% of total assets.
Cash, cash equivalents, and investment securities increased $434.6 million, or 86.9% on an annualized basis, to $1.1 billion as of September 30, 2020 from $667.1 million as of December 31, 2019. The increase was driven by increases in total cash, cash equivalents and investment securities. Cash, cash equivalents, and investment securities were 12.2% of total assets as of September 30, 2020, compared to 8.5% of total assets at December 31, 2019.

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 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, 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.

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.
FHLBB borrowings increased by $82.7 million to $841.2 million as of September 30, 2020 from the December 31, 2019 balance of $758.5 million. The increase in FHLBB borrowings was primarily due to an increase in new advances from the FHLBB to support asset growth.
Subordinated Debentures and Notes
As part of the acquisition of BankRI, the Company acquired two $5.0 million subordinated debentures due on June 26, 2033 and March 17, 2034, respectively. The Company is obligated to pay 3-month LIBOR plus 3.10% and 3-month LIBOR plus 2.79%, respectively, on a quarterly basis until the debentures mature.
The Company sold $75.0 million of 6.0% fixed-to-floating rate subordinated notes due September 15, 2029. The Company is obligated to pay 6.0% interest semiannually between September 2014 and September 2024. Subsequently, the Company is obligated to pay 3-month LIBOR plus 3.315% quarterly until the notes mature in September 2029.

Other Borrowed Funds
In addition to advances from the FHLBB and subordinated debentures and notes, the Company utilizes other funding sources as part of the overall liquidity strategy. Those funding sources include repurchase agreements, and committed and uncommitted lines of credit with several financial institutions.
The Company periodically enters into repurchase agreements with its larger deposit and commercial customers as part of its cash management services which are typically overnight borrowings. Repurchase agreements with customers increased $7.5 million to $50.2 million as of September 30, 2020 from $42.7 million as of December 31, 2019.
The Company has access to a $12.0 million committed line of credit as of September 30, 2020. As of September 30, 2020 and December 31, 2019, the Company did not have any borrowings on this committed line of credit.
The Banks also have access to funding through several uncommitted lines of credit of $605.0 million. As of September 30, 2020, the Company had $30.0 million borrowings on outstanding uncommitted lines of credit as compared to $18.0 million as of December 31, 2019.

Stockholders' Equity and Dividends
The Company's total stockholders' equity was $935.6 million as of September 30, 2020, representing a $10.0 million decrease compared to $945.6 million at December 31, 2019. The decrease primarily reflects dividends paid by the Company of $27.3 million for the nine months ended September 30, 2020, $10.4 million due to repurchase shares of treasury stock, and a reduction to retained earnings of $11.5 million due to the implementation of CECL, partially offset by net income attributable to the Company of $21.0 million, and unrealized gain on securities available-for-sale of $16.5 million.
Stockholders' equity represented 10.39% of total assets as of September 30, 2020 and 12.04% of total assets as of December 31, 2019. Tangible stockholders' equity (total stockholders' equity less goodwill and identified intangible assets, net) represented 8.73% of tangible assets (total assets less goodwill and identified intangible assets, net) as of September 30, 2020 and 10.15% as of December 31, 2019.

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, 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 $2.7 million to $65.9 million for the three months ended September 30, 2020 from $63.2 million for the three months ended September 30, 2019. This increase reflects a $7.3 million decrease in interest income on loans and leases and a $0.1 million increase in interest income on investment securities, offset by a $9.9 million decrease 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, 2020 and September 30, 2019 — Interest Income” and “Results of Operations - Comparison of the Three-Month Period Ended September 30, 2020 and September 30, 2019 — Interest Expense Deposit and Borrowed Funds” below for more details.
Net interest income increased $2.6 million to $191.9 million for the nine months ended September 30, 2020 from $189.4 million for the nine months ended September 30, 2019. This overall increase reflects a $13.8 million decrease in interest income on loans and leases, offset by a $16.4 million decrease 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, 2020 and September 30, 2019 — Interest Income” and “Results of Operations - Comparison of the Nine-Month Period Ended September 30, 2020 and September 30, 2019 — Interest Expense Deposit and Borrowed Funds” below for more details.
Net interest margin decreased by 37 basis points to 3.08% for the three months ended September 30, 2020 from 3.45% for the three months ended September 30, 2019. The Company's weighted average interest rate on loans (prior to purchase accounting adjustments) decreased to 4.12% for the three months ended September 30, 2020 from 5.08% for the three months ended September 30, 2019. The decrease in net interest margin over the period is a result of most asset categories being fully repriced into the current rate environment, while deposit costs decreased at a slower pace than in prior periods.

Table of Contents
Net interest margin decreased by 39 basis points to 3.15% for the nine months ended September 30, 2020 from 3.54% for the nine months ended September 30, 2019. The Company's weighted average interest rate on loans (prior to purchase accounting
adjustments) decreased to 4.35% for the nine months ended September 30, 2020 from 5.10% for the nine months ended September 30, 2019. The decrease in net interest margin over the period is a result of most asset categories being fully repriced into the current rate environment.
The yield on interest-earning assets decreased to 3.79% for the three months ended September 30, 2020 from 4.83% for the three months ended September 30, 2019. This decrease is the result of lower yields on loans and leases and lower yields on investments. During the three months ended September 30, 2020, the Company recorded $1.0 million in prepayment penalties and late charges, which contributed 5 basis points to yields on interest-earning assets in the three months ended September 30, 2020, compared to $0.9 million, or 5 basis points, for the three months ended September 30, 2019.
The yield on interest-earning assets decreased to 4.04% for the nine months ended September 30, 2020 from 4.85% for the nine months ended September 30, 2019. This decrease is the result of lower yields on loans and leases and lower yields on investments. During the nine months ended September 30, 2020, the Company recorded $2.9 million in prepayment penalties and late charges, which contributed 5 basis points to yields on interest-earning assets in the nine months ended September 30, 2020, compared to $2.9 million, or 5 basis points, for the nine months ended September 30, 2019.
The overall cost of funds (including non-interest-bearing demand checking accounts) decreased 72 basis points to 0.75% for the three months ended September 30, 2020 from 1.47% for the three months ended September 30, 2019. The overall cost of funds (including non-interest-bearing demand checking accounts) decreased 46 basis points to 0.98% for the nine months ended September 30, 2020 from 1.44% for the nine months ended September 30, 2019. Refer to "Financial Condition - Borrowed Funds" above for more details.
Management seeks to position the balance sheet to be neutral to asset sensitive to changes in interest rates. From 2017 through 2019, 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 three quarters 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. Due to, among other things, ongoing pricing pressures in the loan and deposit portfolios, net interest income may also be negatively affected by changes in the amount of accretion on acquired loans and leases, deposits and borrowed funds, which is included in interest income and interest expense, respectively.

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 increase in the provision for credit losses for the three and nine months ended September 30, 2020 was primarily driven by changes in macroeconomic forecasts surrounding the COVID-19 pandemic during the first, second, and third quarters of 2020. The latest available economic forecasts were used in the loss models which reflected the immediate and longer term effects of the COVID-19 pandemic onto the Company's allowance for credit losses.
See management’s discussion of “Financial Condition — Allowance for Loan and Lease Losses” and Note 5, “Allowance for Loan and Lease Losses,” to the unaudited consolidated financial statements for a description of how management determined the allowance for loan and lease losses for each portfolio and class of loans.

Other income decreased $0.9 million, or 47.8%, to $0.9 million for the three months ended September 30, 2020 from $1.8 million for the same period in 2019, primarily driven by interest rate derivatives market value adjustment due to volatility in rates and lower rental income. Other income increased $78 thousand, or 1.5%, to $5.1 million for the nine months ended September 30, 2020 from $5.1 million for the same period in 2019.

The Company recorded an income tax expense of $6.6 million for the nine months ended September 30, 2020, compared to $21.2 million income tax expense for the nine months ended September 30, 2019, representing effective tax rates of 23.9% and 24.4%, respectively. The changes in the Company's pre-tax income for the nine months ended September 30, 2020 and 2019 were primarily due to the COVID-19 pandemic and its impact on the Company's provision for loan losses.
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.
In the third quarter, the Company continued to operate with increased liquidity as a precautionary measure due to economic uncertainty associated with the COVID-19 pandemic. In particular, the Company has shifted its balance sheet asset

mix to include additional cash and available for sale securities. Management will continue to monitor the economic markets and evaluate changes to the Company’s liquidity as economic conditions improve.
Management continued holding higher levels of on balance sheet liquidity in the form of cash and available for sale securities in the third quarter. Cash and equivalents at the end of the quarter were $317.3 million, or 3.5% of the balance sheet, compared to $77.8 million, or 1.0% of the balance sheet, as of December 31, 2019. In general, in a normal operating environment, the Company seeks to maintain liquidity levels of cash, cash equivalents and investment securities available-for-sale of between 5% and 10% of total assets. Due to the current environment, management increased this target operating range to between 10% and 15% of total assets. As of September 30, 2020, cash, cash equivalents and investment securities available-for-sale totaled $1.1 billion, or 12.2% 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 $6.8 billion as of September 30, 2020 and represented 87.1% of total funding (the sum of total deposits and total borrowings), compared to deposits of $5.8 billion, or 86.6% of total funding, as of December 31, 2019. Core deposits, which consist of demand checking, NOW, savings and money market accounts, totaled $4.6 billion as of September 30, 2020 and represented 67.8% of total deposits, compared to core deposits of $3.8 billion, or 65.3% of total deposits, as of December 31, 2019. Additionally, the Company had $694.6 million of brokered deposits as of September 30, 2020, which represented 10.2% of total deposits, compared to $349.9 million or 6.0% of total deposits, as of December 31, 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 billion as of September 30, 2020, representing 12.9% of total funding, compared to $902.7 million, or 13.4% of total funding, as of December 31, 2019. The growth in the balance sheet is directly tied to the current operating environment, management will continue to monitor economic conditions and make adjustments to the balance sheet mix as appropriate.
As members of the FHLBB, the Banks have access to both short- and long-term borrowings. As of September 30, 2020, the Company's total borrowing limit from the FHLBB for advances and repurchase agreements was $2.2 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, 2020, the Banks also have access to funding through certain uncommitted lines of credit of $605.0 million.
The Company had a $12.0 million committed line of credit for contingent liquidity as of September 30, 2020. As of September 30, 2020, the Company did not have any outstanding borrowings on this line.
The Company has access to the Federal Reserve Bank's "discount window" to supplement its liquidity. The Company has $683.5 million of borrowing capacity at the Federal Reserve Bank as of September 30, 2020. As of September 30, 2020, the Company did not have any outstanding borrowings with the Federal Reserve Bank.
Additionally, the Banks have access to liquidity through repurchase agreements and additional untapped brokered deposits.
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.

Capital Resources
As of September 30, 2020, the Company and the Banks are each under the primary regulation of, and must comply with, the capital requirements of the FRB. Under these rules, the Company and the Banks are each required to maintain a minimum common equity Tier 1 capital ratio of 4.5%, a minimum Tier 1 capital leverage ratio of 6.0%, a minimum total risk based capital ratio of 8% and a minimum Tier 1 leverage ratio of 4%. Additionally, the Company and the Banks are required to establish a capital conservation buffer of common equity Tier 1 capital in an amount above the minimum risk-based capital requirements for “adequately capitalized” institutions equal to 2.5% of total risk weighted assets, or face restrictions on the ability to pay dividends, pay discretionary bonuses, and to engage in share repurchases. As of September 30, 2020, the Company and the Banks exceeded all regulatory capital requirements, and the Banks were each considered “well-capitalized” under prompt corrective action regulations.

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 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 into 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, 2020 or December 31, 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, 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, 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:

Down 100 basis points ramp(5,635)(2.0)%(11,100)(4.3)%

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 9.6% as of September 30, 2020, compared to a positive 11.5% as of December 31, 2019. The decrease in asset sensitivity was due to a decrease in 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, 2020, the Company’s one-year cumulative gap was a negative $538.1 million, or 6.36% of total interest-earning assets, compared with a positive $4.7 million, or 0.06% of total interest-earning assets, at December 31, 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 2019 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, 2020, simulations for interest rate declines of more than 100 basis points were not deemed to be meaningful.

The Company's EVE sensitivity increased from December 31, 2019 to September 30, 2020 due to the shortened duration of the loan and investment portfolios and a slight extension in the borrowings portfolio.

Item 4. Controls and Procedures
 
Controls and Procedures
 
Under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer (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, including its Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
 
Effective 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 changes in the Company’s internal controls over financial reporting during the quarter ended September 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a -15(f). The Company’s internal control system was designed to provide reasonable assurance to its management and the Board of Directors regarding the preparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. The Company’s management assessed the effectiveness of its internal control over financial reporting as of the end of the period covered by this report.
 
Management’s Report on Internal Control Over Financial Reporting as of December 31, 2019 and the related Report of Independent Registered Public Accounting Firm thereon appear on pages F-1 and F-2 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.

Item 1A.    Risk Factors

This section supplements and updates certain of the information found under Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on February 28, 2020 (“Annual Report”), Item 8.01 “Other Matters” in the Current Report on Form 8-K filed with the SEC on May 11, 2020 (the “May 11, 2020 Form 8-K”), and Part II Item 1.A "Risk Factors" in the Quarterly Report on Form 10-Q filed with the SEC on August 2, 2020 (the "Second Quarter 10-Q"), based on information currently known to us and recent developments since the date of the Second Quarter 10-Q filing. The matters discussed below should be read in conjunction with the risks described in Part I. Item 1A. “Risk Factors” of our Annual Report, Item 8.01 “Other Matters” in the May 11, 2020 Form 8-K, and Part II Item 1A "Risk Factors" of our Second Quarter 10-Q. However, the risks and uncertainties that we face are not limited to those described below and those set forth in the Annual Report, May 11, 2020 Form 8-K and the Second Quarter 10-Q. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business and the trading price of our securities, particularly in light of the fast-changing nature of the COVID-19 pandemic, responsive containment measures taken and the related impacts to economic and operating conditions.

The COVID-19 pandemic, and the measures taken to control its spread, will continue to adversely impact our employees, customers, business operations and financial results, and the ultimate impact will depend on future developments, which are highly uncertain and cannot be predicted.
 
The COVID-19 pandemic has, and will likely continue to, severely impact the national economy and the regional and local markets in which we operate, lower equity market valuations, create significant volatility and disruption in capital and debt markets, and increase unemployment levels. Our business operations may be disrupted if significant portions of our workforce are unable to work effectively, including because of illness, quarantines, government actions, or other restrictions in connection with the pandemic. We are subject to heightened cybersecurity, information security and operational risks as a result of work-from-home arrangements that we have put in place for our employees. Actions taken by the FRB to combat the economic contraction caused by the COVID-19 pandemic, including the reduction of the target federal funds rate and quantitative easing programs, could, if prolonged, adversely affect our net interest income and margins, and our profitability. The continued closures of many businesses and the institution of social distancing, shelter in place and stay home orders in the states and communities we serve, have reduced business activity and financial transactions. Government policies and directives relating to the pandemic response are subject to change as the effects and spread of the COVID-19 pandemic continue to evolve. It is unclear whether any COVID-19 pandemic-related businesses losses that we or our customers may suffer will be covered by existing insurance policies. Additionally, certain government directives and social distancing protocols may hinder our ability to conduct timely property appraisals, which could delay or impact the accuracy of the recognition of credit losses in our loan portfolios. Increases in deposit balances due, among other things, to government stimulus and relief programs could adversely affect our financial performance if we are unable to successfully lend or invest those funds. The measures we have taken to aid our customers, including short-term loan payment deferments, may be insufficient to help our customers who have been negatively impacted by the economic fallout from the COVID-19 pandemic. Loans that are currently in deferral status may become nonperforming loans. Changes in customer behavior due to worsening business and economic conditions or legislative or regulatory initiatives may impact the demand for our products and services, which could adversely affect our revenue, increase the recognition of credit losses in our loan portfolios and increases in our allowance for credit losses. Similarly, because of adverse economic and market conditions affecting issuers, we may be required to recognize further impairments on the securities we hold, goodwill, intangible assets, and deferred tax assets, as well as reductions in other comprehensive income. While the COVID-19 pandemic negatively impacted our results of operations for the first nine months of 2020, the extent to which the COVID-19 pandemic will continue to impact our business, results of operations, and financial condition, as well as our regulatory capital and liquidity ratios, will depend on future developments, including the scope and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic, as well as further actions we may take as may be required by government authorities or that we determine is in the best interests of our employees and customers. There is no certainty that such measures will be sufficient to mitigate the risks posed by the pandemic.

Our participation in the SBA’s PPP may expose us to reputational harm, increased litigation risk, as well as the risk that the SBA may not fund some or all of the guarantees associated with PPP loans.
The Company has funded 2,922 PPP loans totaling $581.7 million as of August 8, 2020 when the program closed, of which $568.4 million remains outstanding, net of deferred fees and costs at September 30, 2020. Lenders participating in the PPP have faced increased public scrutiny about their loan application process and procedures, and the nature and type of the borrowers receiving PPP loans. We depend on our reputation as a trusted and responsible financial services company to compete effectively in the communities that we serve, and any negative public or customer response to, or any litigation or claims that might arise out of, our participation in the PPP and any other legislative or regulatory initiatives and programs that may be enacted in response to the COVID-19 pandemic, could adversely impact our business. Other larger banks have been subject to litigation regarding the process and procedures that such banks used in processing applications for the PPP, and we may be subject to the same or similar litigation, in addition to litigation in connection with our processing of PPP loan forgiveness applications. In addition, if the SBA determines that there is a deficiency in the manner in which a PPP loan was originated, funded, or serviced by us, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if it has already paid under the guaranty, seek recovery of any loss related to the deficiency from us.
