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 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.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	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. The following tables set forth investment securities available-for-sale, held-to-maturity and equity securities held-for-trading at the dates indicated: At September 30, 2020 Amortized Gross Gross Estimated (In Thousands) Investment securities available-for-sale: GSE debentures $ 274,165 $ 6,221 $ 201 $ 280,185 GSE CMOs 50,928 1,266 12 52,182 GSE MBSs 356,282 11,619 19 367,882 Corporate debt obligations 22,328 1,197 — 23,525 U.S. Treasury bonds 55,690 3,912 — 59,602 Foreign government obligations 500 — 9 491 Total investment securities available-for-sale $ 759,893 $ 24,215 $ 241 $ 783,867 Equity securities held-for-trading $ 525 December 31, 2019 Amortized Gross Gross Estimated (In Thousands) Investment securities available-for-sale: GSE debentures $ 182,922 $ 2,939 $ 58 $ 185,803 GSE CMOs 87,001 22 1,091 85,932 GSE MBSs 153,049 797 503 153,343 SBA commercial loan asset-backed securities 34 — — 34 Corporate debt obligations 28,484 502 — 28,986 U.S. Treasury bonds 44,675 338 116 44,897 Total investment securities available-for-sale $ 496,165 $ 4,598 $ 1,768 $ 498,995 Investment securities held-to-maturity: GSE debentures $ 31,228 $ 113 $ 51 $ 31,290 GSEs MBSs 9,360 — 81 9,279 Municipal obligations 45,692 822 — 46,514 Foreign government obligations 500 — 22 478 Total investment securities held-to-maturity $ 86,780 $ 935 $ 154 $ 87,561 Equity securities held-for-trading $ 3,581 As of September 30, 2020, the fair value of all investment securities available-for-sale was $783.9 million, with net unrealized gains of $24.0 million, compared to a fair value of $499.0 million and net unrealized gains of $2.8 million as of December 31, 2019. As of September 30, 2020, $72.9 million, or 9.3% of the portfolio, had gross unrealized losses of $0.2 million, compared to $205.6 million, or 41.2% of the portfolio, with gross unrealized losses of $1.8 million as of December 31, 2019. Effective June 30, 2020, all investment securities classified as held-to-maturity were reclassified as available for sale to prudently reflect the ability and intent to not hold these assets to maturity due to the economic uncertainty created by the 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 totale d $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: At September 30, 2020 Less than Twelve Months Total Estimated Unrealized Estimated Unrealized Estimated Unrealized (In Thousands) Investment securities available-for-sale: GSE debentures $ 56,716 $ 201 $ — $ — $ 56,716 $ 201 GSE CMOs 1,207 7 1,053 5 2,260 12 GSE MBSs 10,670 17 2,768 2 13,438 19 Foreign government obligations — — 491 9 491 9 Temporarily impaired investment securities available-for-sale 68,593 225 4,312 16 72,905 241 Total temporarily impaired investment securities $ 68,593 $ 225 $ 4,312 $ 16 $ 72,905 $ 241 At December 31, 2019 Less than Twelve Months Total Estimated Unrealized Estimated Unrealized Estimated Unrealized (In Thousands) Investment securities available-for-sale: GSE debentures $ 10,965 $ 58 $ — $ — $ 10,965 $ 58 GSE CMOs 28,659 217 55,885 874 84,544 1,091 GSE MBSs 42,046 115 42,257 388 84,303 503 SBA commercial loan asset-backed securities — — 33 — 33 — U.S. Treasury bonds 25,754 116 — — 25,754 116 Temporarily impaired investment securities available-for-sale 107,424 506 98,175 1,262 205,599 1,768 Investment securities held-to-maturity: GSE debentures 8,714 30 2,977 21 11,691 51 GSEs MBSs — — 9,257 81 9,257 81 Municipal obligations 710 — 205 — 915 — Foreign government obligations 478 22 — — 478 22 Temporarily impaired investment securities held-to-maturity 9,902 52 12,439 102 22,341 154 Total temporarily impaired investment securities $ 117,326 $ 558 $ 110,614 $ 1,364 $ 227,940 $ 1,922 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 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"). GSE securities include obligations issued by the Federal National Mortgage Association ("FNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC"), the Government National Mortgage Association ("GNMA"), the FHLBB and the Federal Farm Credit Bank. As of September 30, 2020, the Company held GNMA MBSs and CMOs, and Small Business Administration ("SBA") commercial loan asset-backed securities in its available-for-sale portfolio with an estimated fair value of $8.4 million, all of which were backed explicitly by the full faith and credit of the U.S. Government, compared to $17.4 million as of December 31, 2019. As of September 30, 2020, the Company owned 63 GSE debentures with a total fair value of $280.2 million, and a net unrealized gain of $6.0 million. As of December 31, 2019, the Company held 60 GSE debentures with a total fair value of $185.8 million, with a net unrealized gain of $2.9 million. As of September 30, 2020, 6 of the 63 securities in this portfolio were in an unrealized loss position. As of December 31, 2019, 5 of the 60 securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA/SBA) guarantee of the U.S Government. During the nine months ended September 30, 2020, the Company purchased $208.9 million GSE debentures. This compares to the same period in 2019 when the Company did not purchase any GSE debentures. During the nine months ended September 30, 2020, the Company transferred 9 held-to-maturity GSE debentures with a total fair value of $25.5 million to the available-for-sale portfolio. As of September 30, 2020, the Company owned 33 GSE CMOs with a total fair value of $52.2 million and a net unrealized gain of $1.3 million. As of December 31, 2019, the Company held 61 GSE CMOs with a total fair value of $85.9 million with a net unrealized loss of $1.1 million. As of September 30, 2020, 2 of the 33 securities in this portfolio were in an unrealized loss position. As of December 31, 2019, 45 of the 61 securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA) guarantee of the U.S Government. During the nine months ended September 30, 2020 and 2019, the Company did not purchase any GSE CMOs. As of September 30, 2020, the Company owned 141 GSE MBSs with a total fair value of $367.9 million and a net unrealized gain of $11.6 million. As of December 31, 2019, the Company held 150 GSE MBSs with a total fair value of $153.3 million with a net unrealized gain of $0.3 million. As of September 30, 2020, 18 of the 141 securities in this portfolio were in an unrealized loss position. As of December 31, 2019, 48 of the 150 securities in this portfolio were in an unrealized loss position. All securities are performing and backed by the implicit (FHLB/FNMA/FHLMC) or explicit (GNMA) guarantee of the U.S Government. During the nine months ended September 30, 2020, the Company purchased $258.7 million GSE MBSs. This compares to the same period in 2019 when the Company did not purchase any GSE MBSs. During the nine months ended September 30, 2020, the Company transferred 8 held-to-maturity GSE MBSs with a total fair value of $9.0 million to the available-for-sale portfolio. SBA Commercial Loan Asset-Backed As of September 30, 2020, the Company did not own any SBA securities. As of December 31, 2019, the Company owned 4 SBA securities with a total fair value of $34.0 thousand, which approximated amortized cost. As of December 31, 2019, 3 of the 4 securities in this portfolio were in an unrealized loss position. As of December 31, 2019, all securities are 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. During the nine months ended September 30, 2020, the Company transferred 1 held-to-maturity corporate obligation security with a total fair value of $0.5 million to the available-for-sale portfolio.

As of September 30, 2020, the Company owned 10 U.S. Treasury bonds with a total fair value of $59.6 million and an unrealized gain of $3.9 million. This compares to 9 U.S. Treasury bonds with a total fair value of $44.9 million and an unrealized gain of $0.2 million as of December 31, 2019. As of September 30, 2020, none of the securities in this portfolio were in an unrealized loss position. As of December 31, 2019, 5 of the 9 securities in this portfolio were in unrealized loss positions. During the nine months ended September 30, 2020 the Company purchased $21.2 million U.S. Treasury bonds, compared to the same period in 2019 when the Company did not purchase any U.S. Treasury bonds. Municipal Obligations As of September 30, 2020, the Company did not hold any municipal obligation securities. As of December 31, 2019, the Company owned 93 municipal obligation securities classified as held-to-maturity with a total fair value and total amortized cost of $46.5 million and $45.7 million, respectively. As of December 31, 2019, 6 of the 93 securities in this portfolio were in an unrealized loss position. During the nine months ended September 30, 2019, the Company did not purchase any municipal obligations. Foreign Government Obligations As of September 30, 2020 and December 31, 2019, the Company owned 1 foreign government obligation security with a fair value of $0.5 million, which approximated cost. As of September 30, 2020 and December 31, 2019 respectively, the security was in an unrealized loss position. During the nine months ended September 30, 2020, the Company did not purchase any foreign government obligations, compared to the same period in 2019 when the Company repurchased an existing foreign government obligation that had matured. Equity Securities Held-for-Trading From time to time, the Company will invest in equity securities held-for-trading. As of September 30, 2020 and December 31, 2019, the Company owned equity securities held-for-trading with a fair value of $0.5 million and $3.6 million, respectively.

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.

The following table presents the recorded investments of loans and leases and weighted average coupon rates for the originated and acquired loan and lease portfolios at the date indicated: At December 31, 2019 Originated Acquired Total Balance Weighted Balance Weighted Balance Weighted (Dollars In Thousands) Commercial real estate loans: Commercial real estate $ 2,400,037 4.32 % $ 90,974 4.63 % $ 2,491,011 4.33 % Multi-family mortgage 896,482 4.18 % 35,681 4.59 % 932,163 4.20 % Construction 239,015 5.04 % 7,033 6.73 % 246,048 5.09 % Total commercial real estate loans 3,535,534 4.33 % 133,688 4.73 % 3,669,222 4.34 % Commercial loans and leases: Commercial 713,875 4.65 % 15,627 5.14 % 729,502 4.66 % Equipment financing 1,049,997 7.71 % 2,411 5.98 % 1,052,408 7.71 % Condominium association 56,838 4.84 % — — % 56,838 4.84 % Total commercial loans and leases 1,820,710 6.42 % 18,038 5.25 % 1,838,748 6.41 % Consumer loans: Residential mortgage 711,522 4.06 % 102,723 4.40 % 814,245 4.10 % Home equity 343,247 4.41 % 33,572 4.93 % 376,819 4.46 % Other consumer 38,674 4.44 % 108 17.91 % 38,782 4.48 % Total consumer loans 1,093,443 4.18 % 136,403 4.54 % 1,229,846 4.22 % Total loans and leases $ 6,449,687 4.89 % $ 288,129 4.67 % $ 6,737,816 4.88 % 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: Three Months Ended September 30, Nine Months Ended September 30, 2019 2019 (In Thousands) Balance at beginning of period $ 6,852 $ 7,905 Accretion (1,302) (3,143) Reclassification from nonaccretable difference as a result of changes in expected cash flows 806 1,594 Balance at end of period $ 6,356 $ 6,356 During the three months ended September 30, 2019, accretable yield adjustments totaling $0.8 million were made for certain loan pools. During the nine months ended September 30, 2019, accretable yield adjustments totaling $1.6 million were made for certain loan pools. These accretable yield adjustments, which were subject to continued re-assessment, will be recognized over the remaining lives of those pools. As of September 30, 2019, the accretable yield was fully accreted. Loans and Leases Pledged as Collateral As of September 30, 2020 and 2019, there were $3.5 billion and $2.9 billion respectively of loans and leases pledged as collateral for repurchase agreements; municipal deposits; treasury, tax and loan deposits; swap agreements; FRB borrowings; and FHLBB borrowings. The Banks did not have any outstanding FRB borrowings as of September 30, 2020 and December 31, 2019.

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. Provision for Credit Losses The provisions for credit losses are set forth below for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2020 2019 2020 2019 (In Thousands) Provision for loan and lease losses: Commercial real estate $ (2,721) $ 361 $ 45,217 $ 842 Commercial 8,557 463 15,119 4,744 Consumer (455) 42 501 406 Total provision for loan and lease losses 5,381 866 60,837 5,992 Unfunded credit commitments (853) 5 3,152 (11) Total provision for credit losses $ 4,528 $ 871 $ 63,989 $ 5,981 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. 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 availa ble . 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. 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. The following tables present information regarding individually evaluated and collectively evaluated allowance for loan and lease losses for credit losses on loans and leases at the dates indicated. Periods prior to January 1, 2020 are presented in accordance with accounting rules effective at that time.

Derivatives and Hedging Activit

Derivatives and Hedging Activities	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	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.

Retirement Benefits [Abstract]
Stock Based Compensation	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.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments A description of the valuation methodologies used for assets and liabilities measured at fair value on a recurring and non-recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. There were no changes in the valuation techniques used during the three and nine months ended September 30, 2020 and 2019. Assets and Liabilities Recorded at Fair Value on a Recurring Basis The following tables set forth the carrying value of assets and liabilities measured at fair value on a recurring basis at the dates indicated: Carrying Value as of September 30, 2020 Level 1 Level 2 Level 3 Total (In Thousands) Assets: Investment securities available-for-sale: GSE debentures $ — $ 280,185 $ — $ 280,185 GSE CMOs — 52,182 — 52,182 GSE MBSs — 367,882 — 367,882 Corporate debt obligations — 23,525 — 23,525 U.S. Treasury bonds — 59,602 — 59,602 Foreign government obligations — 491 — $ 491 Total investment securities available-for-sale $ — $ 783,867 $ — $ 783,867 Equity securities held-for-trading $ — $ 525 $ — $ 525 Derivatives designated as hedging instruments: Interest rate derivatives 10 10 Derivatives not designated as hedging instruments: Loan level derivatives — 149,737 — 149,737 Risk participation-out agreements — 2,191 — 2,191 Foreign exchange contracts — 30 — 30 Liabilities: Derivatives not designated as hedging instruments: Loan level derivatives $ — $ 149,737 $ — $ 149,737 Risk participation-in agreements — 434 — 434 Foreign exchange contracts — 20 — 20 Carrying Value as of December 31, 2019 Level 1 Level 2 Level 3 Total (In Thousands) Assets: Investment securities available-for-sale: GSE debentures $ — $ 185,803 $ — $ 185,803 GSE CMOs — 85,932 — 85,932 GSE MBSs — 153,343 — 153,343 SBA commercial loan asset-backed securities — 34 — 34 Corporate debt obligations — 28,986 — 28,986 U.S. Treasury bonds — 44,897 — 44,897 Total investment securities available-for-sale $ — $ 498,995 $ — $ 498,995 Equity securities held-for-trading $ 2,569 $ 1,012 $ — $ 3,581 Loan level derivatives — 59,365 — 59,365 Risk participation-out agreements — 1,229 — 1,229 Foreign exchange contracts — 54 — 54 Liabilities: Loan level derivatives — 59,365 — 59,365 Risk participation-in agreements — 283 — 283 Foreign exchange contracts — 53 — 53 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 Company and its counterparties, its net exposures and remaining contractual life. To date, the Company has not realized any losses due to a counterparty's inability to pay any net uncollateralized position. Refer also to Note 8, "Derivatives and Hedging Activities." There were no transfers between levels for assets and liabilities recorded at fair value on a recurring basis during the three and nine months ended September 30, 2020 and 2019, respectively. Assets and Liabilities Recorded at Fair Value on a Non-Recurring Basis Assets and liabilities measured at fair value on a non-recurring basis are summarized below at the dated indicated: Carrying Value as of September 30, 2020 Level 1 Level 2 Level 3 Total (In Thousands) Assets measured at fair value on a non-recurring basis: Collateral-dependent impaired loans and leases $ — $ — $ 8,838 $ 8,838 Repossessed assets — 1,413 — 1,413 Total assets measured at fair value on a non-recurring basis $ — $ 1,413 $ 8,838 $ 10,251 Carrying Value as of December 31, 2019 Level 1 Level 2 Level 3 Total (In Thousands) Assets measured at fair value on a non-recurring basis: Collateral-dependent impaired loans and leases $ — $ — $ 2,243 $ 2,243 Repossessed assets — 2,631 — 2,631 Total assets measured at fair value on a non-recurring basis $ — $ 2,631 $ 2,243 $ 4,874 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). The table below presents quantitative information about significant unobservable inputs (Level 3) for assets measured at fair value on a non-recurring basis at the dates indicated. Fair Value Valuation Technique At September 30, At December 31, 2019 (Dollars in Thousands) Collateral-dependent impaired loans and leases $ 8,838 $ 2,243 Appraisal of collateral (1) ________________________________________________________________________ (1) Fair value is generally determined through independent appraisals of the underlying collateral. The Company may also use another available source of collateral assessment to determine a reasonable estimate of the fair value of the collateral. 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. Summary of Estimated Fair Values of Financial Instruments The following table presents the carrying amount, estimated fair value, and placement in the fair value hierarchy of the Company's financial instruments at the dates indicated. This table excludes financial instruments for which the carrying amount approximates fair value. Financial assets for which the fair value approximates carrying value include cash and cash equivalents, restricted equity securities, and accrued interest receivable. Financial liabilities for which the fair value approximates carrying value include non-maturity deposits, short-term borrowings, and accrued interest payable. Fair Value Measurements at September 30, 2020 Carrying Estimated Level 1 Level 2 Level 3 (In Thousands) Financial assets: Loans and leases, net $ 7,276,387 $ 7,252,063 $ — $ — $ 7,252,063 Restricted equity securities 61,715 61,715 — — 61,715 Financial liabilities: Certificates of deposits 2,187,466 2,203,487 — 2,203,487 — Borrowed funds 1,005,045 1,006,033 — 1,006,033 — Fair Value Measurements at December 31, 2019 Carrying Estimated Level 1 Level 2 Level 3 (In Thousands) Financial assets: Investment securities held-to-maturity: GSE debentures $ 31,228 $ 31,290 $ — $ 31,290 $ — GSE MBSs 9,360 9,279 — 9,279 — Municipal obligations 45,692 46,514 — 46,514 — Foreign government obligations 500 478 — — 478 Loans and leases, net 6,676,734 6,697,583 — — 6,697,583 Restricted equity securities 53,818 53,818 — — 53,818 Financial liabilities: Certificates of deposit 2,021,642 2,026,683 — 2,026,683 — Borrowed funds 902,749 902,670 — 902,670 — 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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. Financial instruments with off-balance-sheet risk at the dates indicated follow: At September 30, 2020 At December 31, 2019 (In Thousands) Financial instruments whose contract amounts represent credit risk: Commitments to originate loans and leases: Commercial real estate $ 115,630 $ 50,034 Commercial 85,543 78,058 Residential mortgage 29,119 25,998 Unadvanced portion of loans and leases 812,748 808,681 Unused lines of credit: Home equity 564,956 528,251 Other consumer 29,711 25,374 Other commercial 440 380 Unused letters of credit: Financial standby letters of credit 13,411 10,166 Performance standby letters of credit 6,135 4,652 Commercial and similar letters of credit 6,211 3,823 Loan level derivatives (Notional principal amounts): Receive fixed, pay variable 1,243,794 1,101,193 Pay fixed, receive variable 1,243,794 1,101,193 Risk participation-out agreements 254,577 235,693 Risk participation-in agreements 60,874 55,281 Foreign exchange contracts (Notional amounts): Buys foreign currency, sells U.S. currency 1,511 1,125 Sells foreign currency, buys U.S. currency 1,521 1,230 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. Nine Months Ended September 30, 2020 Nine Months Ended September 30, 2019 (In Thousands) The components of lease expense were as follow: Operating lease cost $ 4,828 $ 4,644 Supplemental cash flow information related to leases was as follows: Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for operating leases $ 4,909 $ 4,658 Right-of-use assets obtained in exchange for new lease obligations: Operating leases $ — $ 72 At September 30, 2020 At December 31, 2019 (In Thousands) Supplemental balance sheet information related to leases was as follows: Operating Leases Operating lease right-of-use assets $ 23,492 $ 24,876 Operating lease liabilities 23,492 24,876 Weighted Average Remaining Lease Term Operating leases 7.04 7.47 Weighted Average Discount Rate Operating leases 3.2 % 3.2 % A summary of future minimum rental payments under such leases at the dates indicated follows: Minimum Rental Payments September 30, 2020 (In Thousands) Remainder of 2020 $ 1,545 Year ending: 2021 5,868 2022 5,166 2023 4,147 2024 2,747 2025 1,708 Thereafter 4,924 Total $ 26,105 Less imputed interest (2,613) Present value of lease liability $ 23,492 Certain leases contain escalation clauses for real estate taxes and other expenditures, which are not included above. The total real estate taxes were $1.4 million and other expenditures were $0.3 million for both the nine months ended September 30, 2020, and 2019. Total rental expense was $1.5 million for both the three months ended September 30, 2020, and 2019, respectively. Total rental expense was $4.6 million and $4.4 million for the nine months ended September 30, 2020 and 2019, respectively. Legal Proceedings In the normal course of business, there are various outstanding legal proceedings. In the opinion of management, after consulting with legal counsel, the consolidated financial position and results of operations of the Company are not expected to be affected materially by the outcome of such proceedings.

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Overview Revenue from contracts with customers in the scope of Accounting Standards Codification (“ASC”) ("Topic 606") is measured based on the consideration specified in the contract with a customer and excludes amounts collected on behalf of third parties. The Company recognizes revenue from contracts with customers when it satisfies its performance obligations. The Company’s performance obligations are generally satisfied as services are rendered and can either be satisfied at a point in time or over time. Unsatisfied performance obligations at the report date are not material to our consolidated financial statements. In certain cases, other parties are involved with providing services to our customers. If the Company is a principal in the transaction (providing services itself or through a third party on its behalf), revenues are reported based on the gross consideration received from the customer and any related expenses are reported in gross noninterest expense. If the Company is an agent in the transaction (referring to another party to provide services), the Company reports its net fee or commission retained as revenue. A substantial portion of the Company’s revenue is specifically excluded from the scope of Topic 606. This exclusion is associated with financial instruments, including interest income on loans and investment securities, in addition to loan derivative income and gains on loan and investment sales. For the revenue that is in-scope of Topic 606, the following is a description of principal activities from which the Company generates its revenue from contracts with customers, separated by the timing of revenue recognition. Revenue Recognized at a Point in Time The Company recognizes revenue that is transactional in nature and such revenue is earned at a point in time. Revenue that is recognized at a point in time includes card interchange fees (fee income related to debit card transactions), ATM fees, wire transfer fees, overdraft charge fees, and stop-payment and returned check fees. Additionally, revenue is collected from loan fees, such as letters of credit, line renewal fees and application fees. Such revenue is derived from transactional information and is recognized as revenue immediately as the transactions occur or upon providing the service to complete the customer’s transaction. Revenue Recognized Over Time The Company recognizes revenue over a period of time, generally monthly, as services are performed and performance obligations are satisfied. Such revenue includes commissions on investments, insurance sales and service charges on deposit accounts. Fee revenue from service charges on deposit accounts represents the service charges assessed to customers who hold deposit accounts at the Banks.

Subsequent Events [Abstract]
Subsequent Events	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.

Accounting Policies
Basis of Financial Statement Presentation	Basis of Financial Statement PresentationThe 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.
Consolidation	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.
Use of Estimates	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	Reclassification Certain previously reported amounts have been reclassified to conform to the current year's presentation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Adopted in 2020 In June 2016, the FASB issued ASU 2016-13 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.
