Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Operations The Bancorp is a publicly-owned registered bank holding company that has elected to be a financial holding company. The Bancorp’s principal subsidiary is the Bank, a Rhode Island chartered financial institution founded in 1800. The Bank is the oldest community bank in the nation and the largest state-chartered bank headquartered in Rhode Island. Washington Trust offers a full range of financial services, including commercial, residential and consumer lending, retail and commercial deposit products, and wealth management and trust services through its offices in Rhode Island, Massachusetts and Connecticut. Basis of Presentation The accounting and reporting policies of Washington Trust conform to GAAP and to general practices of the banking industry. The consolidated financial statements include the accounts of the Bancorp and its wholly-owned subsidiaries, except subsidiaries that are not deemed necessary to be consolidated. Intercompany balances and transactions have been eliminated in consolidation. The Bancorp owns the common stock of two capital trusts, which have issued trust preferred securities. These capital trusts are variable interest entities in which the Bancorp is not the primary beneficiary and, therefore, are not consolidated. The capital trust’s only assets are junior subordinated debentures issued by the Bancorp, which were acquired by the capital trusts using the proceeds from the issuance of the trust preferred securities and common stock. The Bancorp’s equity interest in the capital trusts, which is classified in other assets, and the junior subordinated debentures are included in the Consolidated Balance Sheets. Interest expense on the junior subordinated debentures is included in the Consolidated Statements of Income. Reclassification Certain previously reported amounts have been reclassified to conform to the current year’s presentation. Use of Estimates In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ from those estimates. Management considers the ACL on loans to be a material estimate that is particularly susceptible to change. Cash and Cash Equivalents Cash and cash equivalents, as referenced in the accompanying Consolidated Statements of Cash Flows, consists of cash and due from banks and short-term investments. Cash and due from Banks Cash and due from banks includes cash on hand, cash items in process of collection, cash on deposit at the FRBB and other correspondent banks, as well as cash pledged to derivative counterparties. Cash on deposit includes interest-bearing deposits held at correspondent banks of $65.8 million and $128.3 million, respectively, at December 31, 2022 and 2021. Cash collateral pledged to derivative counterparties represents restricted cash balances. See Note 9 for additional disclosure regarding cash collateral pledged to derivative counterparties. Short-term Investments Short-term investments consist of highly liquid investments with a maturity date of three months or less when purchased and are considered to be cash equivalents. The Corporation’s short-term investments may be composed of overnight federal funds sold, securities purchased under resale agreements, money market mutual funds and U.S. Treasury bills. Securities Management determines the appropriate classification of securities at the time of purchase. Investments in debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and carried at amortized cost. Securities not classified as held to maturity are classified as available for sale. Securities available for sale consist of debt securities that are available for sale to respond to changes in market interest rates, liquidity needs, changes in funding sources and other similar factors. These assets are specifically identified and are carried at fair value. Changes in fair value of available for sale securities, net of applicable income taxes, are reported as a separate component of shareholders’ equity. Washington Trust does not currently have securities designated as held to maturity and also does not maintain a trading portfolio. Premiums and discounts are amortized and accreted over the term of the securities on a method that approximates the level yield method. The amortization and accretion is included in interest income on securities. Interest income is recognized when earned. Realized gains or losses from sales of securities are recorded on the trade date and are determined using the specific identification method. The fair values of securities may be based on either quoted market prices or third-party pricing services. The Corporation excludes accrued interest from the amortized cost basis of debt securities and reports accrued interest in other assets in the Consolidated Balance Sheets. The Corporation also excludes accrued interest from the estimate of credit losses on debt securities. 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 as of December 31, 2022 and 2021 and, therefore there was no accrued interest related to debt securities reversed against interest income for 2022 and 2021. Allowance for Credit Losses on Securities For available for sale debt securities in an unrealized loss position, management first assesses whether the Corporation intends to sell, or if it is likely that the Corporation will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through a provision for credit losses charge to earnings. For debt securities available for sale that do not meet either of these criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers both quantitative and qualitative factors. A substantial portion of available for sale debt securities held by the Corporation are obligations issued by U.S. government agency and U.S. government-sponsored enterprises, including mortgage-backed securities. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies and have a long history of no credit losses. For these securities, management takes into consideration the long history of no credit losses and other factors to assess the risk of nonpayment even if the U.S. government were to default. As such, the Corporation utilized a zero credit loss estimate for these securities. For available for sale debt securities that are not guaranteed by U.S. government agencies and U.S. government-sponsored enterprises, such as individual name issuer trust preferred debt securities and corporate bonds, management utilizes a third-party credit modeling tool based on observable market data, which assists management in identifying any potential credit risk associated with these available for sale debt securities. This model estimates probability of default, loss given default and exposure at default for each security. In addition, qualitative factors are also considered, including the extent to which fair value is less than amortized cost, changes to the credit rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If a credit loss exists based on the results of this assessment, an ACL (contra asset) 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 considered market-related and is recognized in other comprehensive income, net of taxes. Changes in the ACL on available for sale debt securities are recorded as provision for credit losses. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Federal Home Loan Bank Stock The Bank is a member of the FHLB. The FHLB is a cooperative that provides services, including funding in the form of advances, to its member banking institutions. As a requirement of membership, the Bank must own a minimum amount of FHLB stock, calculated periodically based primarily on its level of borrowings from the FHLB. No market exists for shares of FHLB stock and therefore, it is carried at cost. FHLB stock may be redeemed at par value five years following termination of FHLB membership, subject to limitations which may be imposed by the FHLB or its regulator, the Federal Housing Finance Board, to maintain capital adequacy of the FHLB. While the Bank currently has no intentions to terminate its FHLB membership, the ability to redeem its investment in FHLB stock would be subject to the conditions imposed by the FHLB. The Bank monitors its investment to determine if impairment exists. Based on the capital adequacy and the liquidity position of the FHLB, management believes there is no impairment related to the carrying amount of FHLB stock included in the Consolidated Balance Sheet as of December 31, 2022. Mortgage Banking Activities Mortgage Loans Held for Sale Residential real estate mortgage loans originated and intended for sale in the secondary market are classified as held for sale. ASC 825, “Financial Instruments” allows for the irrevocable option to elect fair value accounting for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis that may otherwise not be required to be measured at fair value under other accounting standards. The Corporation has elected the fair value option for mortgage loans held for sale in order to better match changes in fair values of the loans with changes in the fair value of the derivative forward sale commitment contracts used to economically hedge them. Changes in the fair value of mortgage loans held for sale accounted for under the fair value option are included in mortgage banking revenues. Gains and losses on residential loan sales are recognized at the time of sale and are included in mortgage banking revenues. Upfront fees and costs related to mortgage loans held for sale for which the fair value option was elected are recognized in mortgage banking revenues as received / incurred and are not deferred. Commissions received on mortgage loans brokered to various investors are recognized when received and included in mortgage banking revenues. Loan Servicing Rights When residential real estate mortgage loans held for sale are sold with servicing retained, mortgage servicing right assets are recognized as separate assets. Mortgage servicing rights are originally recorded at fair value. Fair value is based on a valuation model that incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, ancillary income, prepayment speeds, and default rates and losses. Mortgage servicing rights are included in other assets and are amortized as an offset to mortgage banking revenues over the period of estimated net servicing income. Mortgage servicing rights are periodically evaluated for impairment based on their fair value. Impairment is measured on an aggregated basis by stratifying the rights based on homogeneous characteristics such as note rate and loan type. The fair value is estimated based on the present value of expected cash flows, incorporating assumptions for discount rate, prepayment speed and servicing cost. Any impairment is recognized through a valuation allowance and as a reduction to mortgage banking revenues. Loans Portfolio Loans Loans are carried at the principal amount outstanding, adjusted by partial charge-offs and net of unamortized deferred loan origination fees and costs. Interest income is accrued on a level yield basis based upon principal amounts outstanding, except for loans on nonaccrual status. Deferred loan origination fees and costs are amortized as an adjustment to yield over the term of the related loans. For purchased loans, which did not show signs of credit deterioration at the time of purchase, interest income is also accrued on a level yield basis based upon principal amounts outstanding and is then further adjusted by accretion of any discount or amortization of any premium associated with the loans. Nonaccrual Loans Loans, with the exception of certain well-secured loans that are in the process of collection, are placed on nonaccrual status and interest recognition is suspended when such loans are 90 days or more overdue with respect to principal and/or interest, or sooner if considered appropriate by management. Well-secured loans are permitted to remain on accrual status provided that full collection of principal and interest is assured and the loan is in the process of collection. Loans are also placed on nonaccrual status when, in the opinion of management, full collection of principal and interest is doubtful. When loans are placed on nonaccrual status, interest previously accrued but not collected is reversed against current period income. Subsequent interest payments received on nonaccrual loans are applied to the outstanding principal balance of the loan or recognized as interest income depending on management’s assessment of the ultimate collectability of the loan. Loans are removed from nonaccrual status when they have been current as to principal and interest for a period of time, the borrower has demonstrated an ability to comply with repayment terms, and when, in management’s opinion, the loans are considered to be fully collectible. Troubled Debt Restructured Loans A loan that has been modified or renewed is considered to be a TDR when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower’s benefit that would not otherwise be considered for a borrower or a transaction with similar credit risk characteristics. These concessions may include modifications of the terms of the debt such as deferral of payments, extension of maturity, reduction of principal balance, reduction of the stated interest rate other than normal market rate adjustments, or a combination of these concessions. Debt may be bifurcated with separate terms for each tranche of the restructured debt. Restructuring of a loan in lieu of aggressively enforcing the collection of the loan may benefit the Corporation by increasing the ultimate probability of collection. TDRs are classified as accruing or non-accruing based on management’s assessment of the collectability of the loan. Loans that are already on nonaccrual status at the time of the restructuring generally remain on nonaccrual status for approximately six months before management considers such loans for return to accruing status. Accruing restructured loans are placed into nonaccrual status if and when the borrower fails to comply with the restructured terms and management deems it unlikely that the borrower will return to a status of compliance in the near term and full collection of principal and interest is in doubt. TDRs are reported as such for at least one year from the date of the restructuring. In years after the restructuring, TDRs are removed from this classification if the restructuring did not involve a below-market rate concession and the loan is performing in accordance with their modified contractual terms for a reasonable period of time. The Corporation elected to account for eligible loan modifications under Section 4013 of the CARES Act, as amended by the CRRSA Act. Eligible loan modifications from March 1, 2020 through January 1, 2022 made in response to the COVID-19 pandemic were not required to be classified as TDRs. The vast majority of the loan payment deferral modifications or “deferments” made qualified as eligible loans modifications and were not classified as TDRs. All of these loans with qualified deferments exited their payment deferral period prior to March 31, 2022. Individually Analyzed Loans Individually analyzed loans are individually assessed for credit impairment and include nonaccrual commercial loans, reasonably expected TDRs, executed TDRs, and certain other loans based on the underlying risk characteristics and the discretion of management to individually analyze such loans. A TDR is considered reasonably expected to occur no later than the point when management concludes that modification is the best course of action and it is at least reasonably possible that the troubled borrower will accept some form of concession to avoid a default. Allowance for Credit Losses on Loans The ACL on loans is established through a provision for credit losses recognized in the Consolidated Statements of Income. The ACL on loans is also increased by recoveries of amounts previously charged-off and is reduced by charge-offs on loans. Loan charge-offs are recognized when management believes the collectability of the principal balance outstanding is unlikely. Full or partial charge-offs on collateral dependent individually analyzed loans are generally recognized when the collateral is deemed to be insufficient to support the carrying value of the loan. The ACL on loans is management’s estimate of expected lifetime credit losses on loans carried at amortized cost. The Corporation made an accounting policy election to exclude accrued interest from the amortized cost basis of loans and reports accrued interest in other assets in the Consolidated Balance Sheets. The Corporation also excludes accrued interest from the estimate of credit losses on loans. The level of the ACL on loans is based on management’s ongoing review of all relevant information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the calculation of loss given default and the estimation of expected credit losses. As discussed further below, adjustments to historical information are made for differences in specific risk characteristics, such as differences in underwriting standards, portfolio mix, delinquency level, or term, as well as for changes in environmental conditions, that may not be reflected in historical loss rates. Management employs a process and methodology to estimate the ACL on loans that evaluates both quantitative and qualitative factors. In accordance with the Corporation’s ACL policy, the methodology is reviewed no less than annually. The methodology for evaluating quantitative factors consists of two basic components. The first component involves pooling loans into portfolio segments for loans that share similar risk characteristics. Pooled loan portfolio segments include CRE (including a commercial construction sub-segment), C&I (including a PPP sub-segment), residential real estate, home equity and other consumer loans. The second component involves identifying individually analyzed loans that do not share similar risk characteristics with loans that are pooled into portfolio segments. Individually analyzed loans include nonaccrual commercial loans, reasonably expected TDRs and executed TDRs, as well as certain other loans based on the underlying risk characteristics and the discretion of management to individually analyze such loans. For loans that are individually analyzed, the ACL is measured using a DCF method based upon the loan’s contractual effective interest rate, or at the loan’s observable market price, or, if the loan is collateral dependent, at the fair value of the collateral. Factors management considers when measuring the extent of expected credit loss include payment status, collateral value, borrower financial condition, guarantor support and the probability of collecting scheduled principal and interest payments when due. For collateral dependent loans for which repayment is to be provided substantially through the sale of the collateral, management adjusts the fair value for estimated costs to sell. For collateral dependent loans for which repayment is to be provided substantially through the operation of the collateral, such as accruing TDRs, estimated costs to sell are not incorporated into the measurement. Management may also adjust appraised values to reflect estimated market value declines or apply other discounts to appraised values for unobservable factors resulting from its knowledge of circumstances associated with the collateral. For pooled loans, the Corporation utilizes a DCF methodology to estimate credit losses over the expected life of the loan. The life of the loan excludes expected extensions, renewals and modifications, unless the extension or renewal options are included in the original or modified contract terms and not unconditionally cancellable by the Corporation. The methodology incorporates a probability of default and loss given default framework. Default triggers include the loan has become past due by 90 or more days, a charge-off has occurred, the loan has been placed on nonaccrual status, the loan has been modified in a TDR or the loan is risk-rated as special mention or classified. Loss given default is estimated based on historical credit loss experience. Probability of default is estimated utilizing a regression model that incorporates econometric factors. Econometric factors are selected based on the correlation of the factor to historical credit losses for each portfolio segment. The following table summarizes the econometric factors utilized for each loan portfolio segment as of the dates indicated: Econometric Factors Loan portfolio segment At December 31, 2022 At December 31, 2021 CRE NUR & GDP NUR & GDP C&I NUR & GDP NUR Residential real estate NUR & HPI NUR & HPI Home equity NUR & HPI NUR & HPI Other consumer GDP NUR & GDP To estimate the probability of default, the model utilizes forecasted econometric factors over a one-year reasonable and supportable forecast period. After the forecast period, the model reverts to the historical mean of the respective econometric factor and the associated probability of default on a straight-line basis over a one-year reversion period. The DCF methodology combines the probability of default, the loss given default, prepayment speeds and the remaining life of the loan to estimate a reserve for each loan. The sum of all the loan level reserves are aggregated for each portfolio segment and a loss rate factor is derived. Quantitative loss factors are also supplemented by certain qualitative risk factors reflecting management’s view of how losses may vary from those represented by quantitative loss rates. These qualitative risk factors include: 1) changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; 2) changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; 3) changes in the nature and volume of the portfolio and in the terms of loans; 4) changes in the experience, ability, and depth of lending management and other relevant staff; 5) changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or rated loans; 6) changes in the quality of the institution’s credit review system; 7) changes in the value of underlying collateral for collateral dependent loans; 8) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and 9) the effect of other external factors such as legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio. Qualitative loss factors are applied to each portfolio segment with the range of amounts determined by historical loan charge-offs of a peer group of similar-sized regional banks. Because the methodology is based upon historical experience and trends, current economic data, reasonable and supportable forecasts, as well as management’s judgment, factors may arise that result in different estimations. Deteriorating conditions or assumptions could lead to further increases in the ACL on loans, conversely improving conditions or assumptions could lead to further reductions in the ACL on loans. In addition, various regulatory agencies periodically review the ACL on loans. Such agencies may require additions to the allowance based on their judgments about information available to them at the time of their examination. The ACL on loans is an estimate, and ultimate losses may vary from management’s estimate. Allowance for Credit Losses on Unfunded Commitments The ACL on unfunded commitments is management’s estimate of expected lifetime credit losses over the expected contractual term in which the Corporation is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Corporation. Unfunded commitments for home equity lines of credit and commercial demand loans are considered unconditionally cancellable for regulatory capital purposes and, therefore, are excluded from the calculation to estimate the ACL on unfunded commitments. For each portfolio, estimated loss rates and funding factors are applied to the corresponding balance of unfunded commitments. The estimated loss rates applied to unfunded commitments are the same quantitative and qualitative loss rates applied to the corresponding on-balance sheet amounts in determining the ACL on loans. The estimated funding factor applied to unfunded commitments represents the likelihood that the funding will occur and is based upon the Corporation’s average historical utilization rate for each portfolio. The ACL on unfunded commitments is included in other liabilities in the Consolidated Balance Sheets. The ACL on unfunded commitments is adjusted through a provision for credit losses recognized in the Consolidated Statements of Income. Premises and Equipment Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Depreciation for financial reporting purposes is calculated on the straight-line method over the estimated useful lives of assets. For leasehold improvements, the estimated useful life is the shorter of the expected lease term or the estimated useful life of the improvement. Expected lease terms include lease renewal options to the extent that the exercise of such renewals is reasonably assured. The estimated useful lives of premises and improvements range from 5 to 40 years. For furniture, fixtures and equipment, the estimated useful lives range from 3 to 20 years. Repairs and maintenance costs are charged to noninterest expense as incurred. Leases The Corporation has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. Operating leases are recorded on the balance sheet, through the recognition of an operating lease ROU asset and an operating lease liability at the commencement date of the new lease. ROU assets represent a right to use an underlying asset for the contractual lease term. Operating lease liabilities represent an obligation to make lease payments arising from the lease. The Corporation’s leases do not provide an implicit interest rate, therefore the Corporation uses its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine the present value of operating lease liabilities. The Corporation’s operating lease agreements contain both lease and non-lease components, which are generally accounted for separately. The Corporation’s lease agreements do not contain any residual value guarantees. Operating leases with terms of 12 months or less are included in ROU assets and operating lease liabilities recorded in the Consolidated Balance Sheets. Operating lease terms include options to extend when it is reasonably certain that the Corporation will exercise such options, determined on a lease-by-lease basis. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease components, such as consumer price index adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities. Bank-Owned Life Insurance The investment in BOLI represents the cash surrender value of life insurance policies on the lives of certain employees who have provided positive consent allowing the Bank to be the beneficiary of such policies. Increases in the cash value of the policies, as well as insurance proceeds received, are recorded in noninterest income and are not subject to income taxes. The financial strength of the insurance carrier is reviewed prior to the purchase of BOLI and annually thereafter. Goodwill and Identifiable Intangible Assets Goodwill represents the excess of the purchase price over the net fair value of the acquired businesses. Goodwill is not amortized, but is tested for impairment at the reporting unit level (defined as the segment level), at least annually in the fourth quarter or more frequently whenever events or circumstances occur that indicate that it is more-likely-than-not that an impairment loss has occurred. In assessing impairment, the Corporation has the option to perform a qualitative analysis to determine whether the existence of events or circumstances leads to a determination that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount. If, after assessing the totality of such events or circumstances, we determine it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, then we would not be required to perform an impairment test. The quantitative impairment analysis requires a comparison of each reporting unit’s fair value to its carrying value to identify potential impairment. Goodwill impairment exists when a reporting unit’s carrying value of goodwill exceeds its implied fair value. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes, but may not be limited to, the selection of appropriate discount rates, the identification of relevant market comparables and the development of cash flow projections. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weightings that are most representative of fair value. Intangible assets identified in acquisitions consist of advisory contracts. The value attributed to intangible assets was based on the time period over which they are expected to generate economic benefits. Intangible assets are amortized over their estimated lives using a method that approximates the amount of economic benefits that are realized by the Corporation. Intangible assets with definite lives are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. If applicable, the Corporation tests each of the intangibles by comparing the carrying value of the intangible asset to the sum of undiscounted cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its undiscounted cash flows, then an impairment loss would be recognized for the amount by which the carrying amount exceeds its fair value. Impairment would result in a write-down to the estimated fair value based on the anticipated discounted future cash flows. The remaining useful life of the intangible assets that are being amortized is also evaluated to determine whether events and circumstances warrant a revision to the remaining period of amortization.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Standards Adopted in 2022 There were no recently issued accounting pronouncements, applicable to the Corporation, that were adopted in 2022. Accounting Standards Pending Adoption Business Combinations - ASC 805 ASU No. 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (“ASU 2021-08”), was issued in October 2021 to clarify the accounting for contract cost assets and contract liabilities acquired in a business combination. Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination at fair value on the acquisition date. The provisions of ASU 2021-08 clarify that contract cost assets and contract liabilities acquired in a business combination should be accounted for in accordance with ASC 606 as if the acquirer had originated the contracts. ASU 2021-08 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. The provisions under ASU 2021-08 are required to be applied prospectively. The adoption of ASU 2021-08 is not expected to have a material impact on the Corporation’s consolidated financial statements. Financial Instruments - Credit Losses - ASC 326 ASU No. 2022-02, “Troubled Debt Restructurings and Vintage Disclosures” (“ASU 2022-02”), was issued in March 2022 to provide updates on the accounting treatment for TDRs and related disclosures requirements, as well as modifying the disclosure requirement associated with the existing credit quality indicators “vintage” disclosure. With respect to TDRs, ASU 2022-02 eliminates the recognition and measurement guidance for TDRs under current GAAP and instead requires that the Corporation evaluate whether the modification represents a new loan or a continuation of existing loan, consistent with the current GAAP treatment for other loan modifications. In addition, ASU 2022-02 eliminates existing disclosure requirements on TDRs and replaces with enhanced disclosure requirements related to loan modifications made to borrowers, including those experiencing financial difficulty. ASU 2022-02 also provides an update to the existing tabular vintage disclosure of credit quality indicators by requiring current period gross write-offs to be disclosed by year of origination for each loan segment. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. The provisions under ASU 2022-02 should be applied on a prospective basis. However, the Corporation has the option to use a modified retrospective transition method related to the change in accounting treatment for TDRs with a cumulative effect of the change in accounting principle recognized in the opening balance of retained earnings as of the adoption date. The adoption of this ASU is not expected to have a material impact on the consolidated financial statements. Reference Rate Reform - ASC 848 ASU No. 2022-06, “Deferral of the Sunset Date of Topic 848” (“ASU 2022-06”), was issued in December 2022 and defers the date for which accounting relief can be applied under Topic 848. ASU 2022-06 applies to entities that have contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The objective of the guidance in Topic 848 is to ease the burden in accounting for recognizing the effects of reference rate reform on financial reporting. A sunset provision was included within Topic 848 based on expectations of when LIBOR would cease being published. The Corporation had adopted the accounting relief provisions of Topic 848 effective October 1, 2020. The amendments in ASU 2022-06 defer the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be able to apply the accounting relief in Topic 848. ASU 2022-06 was effective for all entities upon its issuance. The adoption of the provisions of Topic 848, as amended, did not have a material impact on the Corporation’s consolidated financial statements.

At December 31, 2022 and 2021, securities with a fair value of $294.8 million and $332.0 million, respectively, were pledged as collateral for FHLB borrowings, potential borrowings with the FRBB, certain public deposits and for other purposes. See Note 13 for additional discussion of FHLB borrowings. The schedule of maturities of available for sale debt securities is presented below. Mortgage-backed securities are included based on weighted average maturities, adjusted for anticipated prepayments. All other debt securities are included based on contractual maturities. Actual maturities may differ from amounts presented because certain issuers have the right to call or prepay obligations with or without call or prepayment penalties.

Final maturities of the callable securities range from 2 years to 14 years, with call features ranging from 1 month to 11 months. Assessment of Available for Sale Debt Securities for Impairment Management assesses the decline in fair value of investment securities on a regular basis. Unrealized losses on debt securities may occur from current market conditions, increases in interest rates since the time of purchase, a structural change in an investment, volatility of earnings of a specific issuer, or deterioration in credit quality of the issuer. Management evaluates both qualitative and quantitative factors to assess whether an impairment exists. The following tables summarize temporarily impaired securities, segregated by length of time the securities have been in a continuous unrealized loss position: (Dollars in thousands) Less than 12 Months 12 Months or Longer Total December 31, 2022 # Fair Unrealized # Fair Unrealized # Fair Unrealized Obligations of U.S. government-sponsored enterprises 4 $20,115 ($638) 18 $169,466 ($30,984) 22 $189,581 ($31,622) Mortgage-backed securities issued by U.S. government agencies and U.S. government-sponsored enterprises 95 288,777 (24,960) 66 471,355 (113,788) 161 760,132 (138,748) Individual name issuer trust preferred debt securities — — — 3 8,760 (627) 3 8,760 (627) Corporate bonds — — — 4 11,484 (1,685) 4 11,484 (1,685) Total temporarily impaired securities 99 $308,892 ($25,598) 91 $661,065 ($147,084) 190 $969,957 ($172,682) (Dollars in thousands) Less than 12 Months 12 Months or Longer Total December 31, 2021 # Fair Unrealized # Fair Unrealized # Fair Unrealized Obligations of U.S. government-sponsored enterprises 12 $152,733 ($3,313) 6 $43,202 ($1,198) 18 $195,935 ($4,511) Mortgage-backed securities issued by U.S. government agencies and U.S. government-sponsored enterprises 41 514,419 (7,270) 21 108,983 (2,937) 62 623,402 (10,207) Individual name issuer trust preferred debt securities — — — 3 9,138 (235) 3 9,138 (235) Corporate bonds — — — 4 12,305 (850) 4 12,305 (850) Total temporarily impaired securities 53 $667,152 ($10,583) 34 $173,628 ($5,220) 87 $840,780 ($15,803) The Corporation does not intend to sell these debt securities and has determined, based upon available evidence, that it is more likely than not that the Corporation will not be required to sell each security before the recovery of its amortized cost basis and management does not believe that any of the securities are impaired due to reasons of credit quality. As a result, the Corporation did not recognize a provision for credit losses on these securities for the years ended December 31, 2022 and 2021. As a result of the Corporation’s review of these qualitative and quantitative factors mentioned below, management believes the unrealized losses on these debt securities are primarily attributable to changes in the investment spreads and interest rates and not changes in the credit quality of the issuers of the debt securities. Obligations of U.S. Government Agency and U.S. Government-Sponsored Enterprise Securities, including Mortgage-Backed Securities The contractual cash flows for these securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies and have a long history of no credit losses. The issuers of these securities continue to make timely principal and interest payments and none of these securities were past due at December 31, 2022. As disclosed in Note 1, the Corporation utilizes a zero credit loss estimate for these securities. Individual Name Issuer Trust Preferred Debt Securities These securities in an unrealized loss position at December 31, 2022 included three trust preferred securities issued by three individual companies in the banking sector. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of December 31, 2022, there was one individual name issuer trust preferred debt security with an amortized cost of $2.0 million and unrealized losses of $134 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between December 31, 2022 and the filing date of this report. Based on the information available through the filing date of this report, all individual name issuer trust preferred debt securities continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers. Corporate Bonds These securities in an unrealized loss position at December 31, 2022 included four corporate bond holdings issued by three individual companies in the financial services industry. Management reviewed the collectability of these securities taking into consideration such factors as the financial condition of the issuers, reported regulatory capital ratios of the issuers, credit ratings, including ratings in effect as of the reporting period date, as well as credit rating changes between the reporting period date and the filing date of this report, and other information. As of December 31, 2022, there was one corporate bond debt security with an amortized cost of $2.0 million and unrealized losses of $136 thousand that was rated below investment grade by S&P. We noted no downgrades to below investment grade between December 31, 2022 and the filing date of this report. Based on the information available through the filing date of this report, all corporate bond debt securities continue to accrue interest and make payments as expected with no payment deferrals or defaults on the part of the issuers.

See Note 13 for additional disclosure regarding borrowings. Concentrations of Credit Risk A significant portion of our loan portfolio is concentrated among borrowers in southern New England and a substantial portion of the portfolio is collateralized by real estate in this area. The ability of single family residential and consumer borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the market area and real estate values. The ability of commercial borrowers to honor their repayment commitments is dependent on the general economy, as well as the health of the real estate economic sector in the Corporation’s market area. Past Due Loans Past due status is based on the contractual payment terms of the loan.

In 2022 and 2021, there were no TDRs modified within the previous 12 months for which there was a payment default. Individually Analyzed Loans Individually analyzed loans include nonaccrual commercial loans, reasonably expected TDRs, executed TDRs, and certain other loans based on the underlying risk characteristics and the discretion of management to individually analyze such loans. As of December 31, 2022, the carrying value of individually analyzed loans amounted to $10.0 million, of which $8.5 million were considered collateral dependent. For collateral dependent loans where management has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and repayment of the loan is to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. See Note 10 for additional disclosure regarding fair value of individually analyzed collateral dependent loans.

Credit Quality Indicators Commercial The Corporation utilizes an internal rating system to assign a risk to each of its commercial loans. Loans are rated on a scale of 1 to 10. This scale can be assigned to three broad categories including “pass” for ratings 1 through 6, “special mention” for 7-rated loans, and “classified” for loans rated 8, 9 or 10. The loan risk rating system takes into consideration parameters including the borrower’s financial condition, the borrower’s performance with respect to loan terms, the adequacy of collateral, the adequacy of guarantees and other credit quality characteristics. The takes the risk rating into consideration along with other credit attributes in the establishment of an appropriate ACL on loans. See Note 5 for additional information. A description of the commercial loan categories is as follows: Pass - Loans with acceptable credit quality, defined as ranging from superior or very strong to a status of lesser stature. Superior or very strong credit quality is characterized by a high degree of cash collateralization or strong balance sheet liquidity. Lesser stature loans have an acceptable level of credit quality, but may exhibit some weakness in various credit metrics such as collateral adequacy, cash flow, performance or may be in an industry or of a loan type known to have a higher degree of risk. These weaknesses may be mitigated by secondary sources of repayment, including SBA guarantees. Special Mention - Loans with potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Bank’s position as creditor at some future date. Special Mention assets are not adversely classified and do not expose the Bank to sufficient risk to warrant adverse classification. Examples of these conditions include but are not limited to outdated or poor quality financial data, strains on liquidity and leverage, losses or negative trends in operating results, marginal cash flow, weaknesses in occupancy rates or trends in the case of commercial real estate and frequent delinquencies. Classified - Loans identified as “substandard,” “doubtful” or “loss” based on criteria consistent with guidelines provided by banking regulators. A “substandard” loan has defined weaknesses which make payment default or principal exposure likely, but not yet certain. Such loans are apt to be dependent upon collateral liquidation, a secondary source of repayment or an event outside of the normal course of business. The loans are closely watched and are either already on nonaccrual status or may be placed on nonaccrual status when management determines there is uncertainty of collectability. A “doubtful” loan is placed on nonaccrual status and has a high probability of loss, but the extent of the loss is difficult to quantify due to dependency upon collateral having a value that is difficult to determine or upon some near-term event which lacks certainty. A loan in the “loss” category is considered generally uncollectible or the timing or amount of payments cannot be determined. “Loss” is not intended to imply that the loan has no recovery value, but rather, it is not practical or desirable to continue to carry the asset. The Corporation’s procedures call for loan risk ratings and classifications to be revised whenever information becomes available that indicates a change is warranted. On a quarterly basis, management reviews a watched asset list, which generally consists of commercial loans that are risk-rated 6 or worse, highly leveraged transaction loans, high-volatility commercial real estate and other selected loans. Management’s review focuses on the current status of the loans, the appropriateness of risk ratings and strategies to improve the credit. An annual credit review program is conducted by a third party to provide an independent evaluation of the creditworthiness of the commercial loan portfolio, the quality of the underwriting and credit risk management practices and the appropriateness of the risk rating classifications. This review is supplemented with selected targeted internal reviews of the commercial loan portfolio. Residential and Consumer Management monitors the relatively homogeneous residential real estate and consumer loan portfolios on an ongoing basis using delinquency information by loan type. In addition, other techniques are utilized to monitor indicators of credit deterioration in the residential real estate loans and home equity consumer loans. Among these techniques is the periodic tracking of loans with an updated Fair Isaac Corporation (commonly known as “FICO”) score and an updated estimated LTV ratio. LTV is estimated based on such factors as geographic location, the original appraised value and changes in median home prices, and takes into consideration the age of the loan. The results of these analyses and other credit review procedures, including selected targeted internal reviews, are taken into account in the determination of qualitative loss factors for residential real estate and home equity consumer credits.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments The Corporation’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Corporation’s known or expected cash receipts and its known or expected cash payments principally to manage the Corporation’s interest rate risk. Additionally, the Corporation enters into interest rate derivatives to accommodate the business requirements of its customers. All derivatives are recognized as either assets or liabilities on the balance sheet and are measured at fair value. Derivative assets are included in other assets and derivative liabilities are included in other liabilities in the Consolidated Balance Sheets. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and resulting designation. Interest Rate Risk Management Agreements Interest rate risk management agreements, such as caps, swaps and floors, are used from time to time as part of the Corporation’s interest rate risk management strategy. Interest rate swaps are agreements in which the Corporation and another party agree to exchange interest payments (e.g., fixed-rate for variable-rate payments) computed on a notional principal amount. Interest rate caps and floors represent options purchased by the Corporation to manage the interest rate paid throughout the term of the option contract. The credit risk associated with these transactions is the risk of default by the counterparty. To minimize this risk, the Corporation enters into interest rate agreements only with highly rated counterparties that management believes to be creditworthy. The notional amounts of these agreements do not represent amounts exchanged by the parties and, thus, are not a measure of the potential loss exposure. Cash Flow Hedging Instruments As of December 31, 2022 and 2021, the Corporation had an interest rate swap contract that was designated as a cash flow hedge to hedge the interest rate risk associated with short-term variable rate FHLB advances. The interest rate swap on borrowings matures in December 2023. In addition, at December 31, 2022, and 2021, the Corporation had an interest rate swap contract that was designated as a cash flow hedge to hedge the interest rate risk associated with a pool of variable rate commercial loans. The interest rate swap on loans matures in May 2026. The changes in fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income (loss) and subsequently reclassified to earnings when gains or losses are realized. Loan Related Derivative Contracts Interest Rate Derivative Contracts with Customers The Corporation enters into interest rate swap and interest rate cap contracts to help commercial loan borrowers manage their interest rate risk. These interest rate swap contracts allow borrowers to convert variable-rate loan payments to fixed-rate loan payments, while interest rate cap contracts allow borrowers to limit their interest rate exposure in a rising rate environment. When the Corporation enters into an interest rate derivative contract with a commercial loan borrower, it simultaneously enters into a “mirror” interest rate contract with a third party. For interest rate swaps, the third party exchanges the client’s fixed-rate loan payments for variable-rate loan payments. The Corporation retains the risk that is associated with the potential failure of counterparties and the risk inherent in originating loans. These derivatives are not designated as hedges and therefore, changes in fair value are recognized in earnings. Risk Participation Agreements The Corporation has entered into risk participation agreements with other banks in commercial loan arrangements. Participating banks guarantee the performance on borrower-related interest rate swap contracts. These derivatives are not designated as hedges and therefore, changes in fair value are recognized in earnings. Under a risk participation-out agreement, a derivative asset, the Corporation participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Corporation assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower for a fee received from the other bank. Mortgage Loan Commitments Interest rate lock commitments are extended to borrowers and relate to the origination of mortgage loans held for sale. To mitigate the interest rate risk and pricing risk associated with rate locks and mortgage loans held for sale, the Corporation enters into forward sale commitments. Forward sale commitments are contracts for delayed delivery or net settlement of the underlying instrument, such as a residential real estate mortgage loan, where the seller agrees to deliver on a specified future date, either a specified instrument at a specified price or yield or the net cash equivalent of an underlying instrument. Both interest rate lock commitments and forward sale commitments are derivative financial instruments, but do not meet criteria for hedge accounting and therefore, the changes in fair value of these commitments are recognized in earnings.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Corporation uses fair value measurements to record fair value adjustments on certain assets and liabilities and to determine fair value disclosures. Items recorded at fair value on a recurring basis include securities available for sale, mortgage loans held for sale and derivatives. Additionally, from time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as collateral dependent individually analyzed loans, OREO and mortgage servicing rights. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write-downs of individual assets. Fair value is a market-based measurement, not an entity-specific measurement. Fair value measurements are determined based on the assumptions the market participants would use in pricing the asset or liability. In addition, GAAP specifies a hierarchy of valuation techniques based on whether the types of valuation information, or “inputs”, are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Corporation’s market assumptions. These two types of inputs have created the following fair value hierarchy: • Level 1 – Quoted prices for identical assets or liabilities in active markets. • Level 2 – Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. • Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable in the markets and which reflect the Corporation’s market assumptions. Fair Value Option Election GAAP allows for the irrevocable option to elect fair value accounting for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis. The Corporation has elected the fair value option for mortgage loans held for sale to better match changes in fair value of the loans with changes in the fair value of the forward sale commitment contracts used to economically hedge them. The following table presents a summary of mortgage loans held for sale accounted for under the fair value option: (Dollars in thousands) December 31, 2022 2021 Aggregate fair value $8,987 $40,196 Aggregate principal balance 8,860 39,201 Difference between fair value and principal balance $127 $995 Changes in fair value of mortgage loans held for sale accounted for under the fair value option election are included in mortgage banking revenues in the Consolidated Statements of Income. Changes in fair value amounted to a decrease to mortgage banking revenues of $868 thousand in 2022, compared to a decrease to mortgage banking revenues of $1.3 million in 2021. There were no mortgage loans held for sale 90 days or more past due as of December 31, 2022 and 2021. Valuation Techniques Debt Securities Available for sale debt securities are recorded at fair value on a recurring basis. When available, the Corporation uses quoted market prices to determine the fair value of debt securities; such items are classified as Level 1. There were no Level 1 securities held at December 31, 2022 and 2021. Level 2 debt securities are traded less frequently than exchange-traded instruments. The fair value of these securities is determined using matrix pricing with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category includes obligations of U.S. government-sponsored enterprises, including mortgage-backed securities, individual name issuer trust preferred debt securities and corporate bonds. Debt securities not actively traded whose fair value is determined through the use of cash flows utilizing inputs that are unobservable are classified as Level 3. There were no Level 3 securities held at December 31, 2022 and 2021. Mortgage Loans Held for Sale The Corporation has elected the fair value option for mortgage loans held for sale. The fair value is estimated based on current market prices for similar loans in the secondary market and therefore are classified as Level 2 assets. Collateral Dependent Individually Analyzed Loans Collateral dependent individually analyzed loans are valued based upon the lower of amortized cost or fair value. Fair value is determined based on the appraised value of the underlying collateral. Such collateral primarily consists of real estate and, to a lesser extent, other business assets. For collateral dependent loans that are expected to be repaid substantially through the sale of the collateral, management adjusts the fair value for estimated costs to sell. Management may also adjust appraised values to reflect estimated market value declines or apply other discounts to appraised values resulting from its knowledge of the collateral. Internal valuations may be utilized to determine the fair value of other business assets. Collateral dependent individually analyzed loans are categorized as Level 3. Derivatives Interest rate derivative contracts are traded in over-the-counter markets where quoted market prices are not readily available. Fair value measurements are determined using independent valuation software, which utilizes the present value of future cash flows discounted using market observable inputs such as forward rate assumptions. The Corporation evaluates the credit risk of its counterparties, as well as that of the Corporation. Accordingly, factors such as the likelihood of default by the Corporation and its counterparties, its net exposures and remaining contractual life are considered in determining if any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions that are subject to master netting agreements, as well as considering the amount of collateral securing the position, if any. The Corporation has determined that the majority of the inputs used to value its derivative positions fall within Level 2 of the fair value hierarchy. However, the credit valuation adjustments utilize Level 3 inputs. As of December 31, 2022 and 2021, the Corporation has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation. As a result, the Corporation has classified its derivative valuations in their entirety as Level 2. Fair value measurements of forward loan commitments (interest rate lock commitments and forward sale commitments) are primarily based on current market prices for similar assets in the secondary market for mortgage loans and therefore are classified as Level 2 assets. The fair value of interest rate lock commitments is also dependent on the ultimate closing of the loans. Pull-through rates are based on the Corporation’s historical data and reflect the Corporation’s best estimate of the likelihood that a commitment will result in a closed loan. Although the pull-through rates are Level 3 inputs, the Corporation has assessed the significance of the impact of pull-through rates on the overall valuation of its interest rate lock commitments and has determined that they are not significant to the overall valuation. As a result, the Corporation has classified its interest rate lock commitments as Level 2.

Equity [Abstract]
Shareholders' Equity	Shareholders' Equity Stock Repurchase Program On December 12, 2022, the Corporation announced that its Board of Directors adopted the 2023 Repurchase Program, which authorizes the repurchase of up to 850,000 shares, or approximately 5%, of the Corporation’s outstanding common stock. This authority may be exercised from time to time and in such amounts as market conditions warrant, and subject to regulatory considerations. The timing and actual numbers of shares repurchased will depend on a variety of factors including price, corporate and regulatory requirements, market conditions, and other corporate liquidity requirements and priorities. The 2023 Repurchase Program commenced on January 1, 2023 and expires on December 31, 2023 and may be modified, suspended, or discontinued at any time. The 2021 Repurchase Program expired on December 31, 2022. For the year ended December 31, 2022, the Corporation repurchased 194,162 shares at an average price of $48.82 and a total cost of $9.5 million, under its 2021 Repurchase Program. Dividends The primary source of liquidity for the Bancorp is dividends received from the Bank. The Bancorp and the Bank are regulated enterprises and their abilities to pay dividends are subject to regulatory review and restriction. Certain regulatory and statutory restrictions exist regarding dividends, loans, and advances from the Bank to the Bancorp. Generally, the Bank has the ability to pay dividends to the Bancorp subject to minimum regulatory capital requirements. The FDIC and the FRBB have the authority to use their enforcement powers to prohibit a bank or bank holding company, respectively, from paying dividends if, in their opinion, the payment of dividends would constitute an unsafe or unsound practice. Dividends paid by the Bank to the Bancorp amounted to $53.2 million and $45.7 million, respectively, for the years ended December 31, 2022 and 2021. Regulatory Capital Requirements The Bancorp and the Bank are subject to various regulatory capital requirements administered by the FRBB and the FDIC, respectively. Regulatory authorities can initiate certain mandatory actions if the Bancorp or the Bank fail to meet minimum capital requirements, which could have a direct material effect on the Corporation’s financial statements. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. These quantitative measures, to ensure capital adequacy, require minimum amounts and ratios. Capital levels at December 31, 2022 exceeded the regulatory minimum levels to be considered “well capitalized.” The following table presents the Corporation’s and the Bank’s actual capital amounts and ratios, as well as the corresponding minimum and well capitalized regulatory amounts and ratios that were in effect during the respective periods: (Dollars in thousands) Actual For Capital Adequacy To Be “Well Capitalized” Under Prompt Corrective Action Regulations Amount Ratio Amount Ratio Amount Ratio December 31, 2022 Total Capital (to Risk-Weighted Assets): Corporation $605,005 12.37 % $391,363 8.00 % N/A N/A Bank 588,090 12.02 391,260 8.00 $489,074 10.00 % Tier 1 Capital (to Risk-Weighted Assets): Corporation 571,794 11.69 293,522 6.00 N/A N/A Bank 554,879 11.35 293,445 6.00 391,260 8.00 Common Equity Tier 1 Capital (to Risk-Weighted Assets): Corporation 549,798 11.24 220,142 4.50 N/A N/A Bank 554,879 11.35 220,083 4.50 317,898 6.50 Tier 1 Capital (to Average Assets): (1) Corporation 571,794 8.65 264,295 4.00 N/A N/A Bank 554,879 8.40 264,177 4.00 330,222 5.00 December 31, 2021 Total Capital (to Risk-Weighted Assets): Corporation 578,137 14.01 330,105 8.00 N/A N/A Bank 565,087 13.70 330,025 8.00 412,532 10.00 Tier 1 Capital (to Risk-Weighted Assets): Corporation 546,362 13.24 247,578 6.00 N/A N/A Bank 533,312 12.93 247,519 6.00 330,025 8.00 Common Equity Tier 1 Capital (to Risk-Weighted Assets): Corporation 524,363 12.71 185,684 4.50 N/A N/A Bank 533,312 12.93 185,639 4.50 268,146 6.50 Tier 1 Capital (to Average Assets): (1) Corporation 546,362 9.36 233,534 4.00 N/A N/A Bank 533,312 9.14 233,434 4.00 291,793 5.00 (1) Leverage ratio. In addition to the minimum regulatory capital required for capital adequacy purposes outlined in the table above, the Corporation is required to maintain a minimum capital conservation buffer, in the form of common equity, of 2.50% in order to avoid restrictions on capital distributions and discretionary bonuses. The Corporation’s capital levels exceeded the minimum regulatory capital requirements plus the capital conservation buffer at December 31, 2022 and 2021. The Bancorp owns the common stock of two capital trusts, which have issued trust preferred securities. In accordance with GAAP, the capital trusts are treated as unconsolidated subsidiaries. At both December 31, 2022 and 2021, $22.0 million in trust preferred securities were included in the Tier 1 capital of the Corporation for regulatory capital reporting purposes pursuant to the capital adequacy guidelines of the Federal Reserve. In accordance with regulatory capital rules, the Corporation elected the option to delay the estimated impact of ASC 326 on its regulatory capital over a two-year deferral and subsequent three-year transition period ending December 31, 2024. As a result, capital ratios exclude the full impact of the increased ACL on loans and unfunded loan commitments attributed to the adoption of ASC 326, adjusted for an approximation of the after-tax provision for credit losses attributable to ASC 326

Receivables amounted to $5.1 million and $6.6 million, respectively, at December 31, 2022 and 2021 and were included in other assets in the Consolidated Balance Sheets. Deferred revenues, which are considered contract liabilities under ASC 606, represent advance consideration received from customers for which the Corporation has a remaining performance obligation to fulfill. Contract liabilities are recognized as revenue over the life of the contract as the performance obligations are satisfied. The balances of contract liabilities were insignificant at both December 31, 2022 and 2021 and were included in other liabilities in the Consolidated Balance Sheets.

Retirement Benefits [Abstract]
Employee Benefits	Employee Benefits Defined Benefit Pension Plans Washington Trust maintains a qualified pension plan for the benefit of certain eligible employees who were hired prior to October 1, 2007. Washington Trust also has non-qualified retirement plans to provide supplemental retirement benefits to certain employees, as defined in the plans. The defined benefit pension plans were previously amended to freeze benefit accruals after a 10-year transition period ending in December 2023. The qualified pension plan is funded on a current basis, in compliance with the requirements of ERISA. Pension benefit costs and benefit obligations incorporate various actuarial and other assumptions, including discount rates, mortality, rates of return on plan assets and compensation increases. Washington Trust evaluates these assumptions annually. The following table presents the plans’ projected benefit obligations, fair value of plan assets and funded (unfunded) status: (Dollars in thousands) Qualified Non-Qualified At December 31, 2022 2021 2022 2021 Change in Benefit Obligation: Benefit obligation at beginning of period $89,408 $94,742 $17,717 $17,973 Service cost 2,062 2,369 218 208 Interest cost 2,368 2,004 423 337 Actuarial (gain) loss (23,658) (4,011) (3,880) 102 Benefits paid (3,422) (5,556) (916) (903) Administrative expenses (102) (140) — — Benefit obligation at end of period 66,656 89,408 13,562 17,717 Change in Plan Assets: Fair value of plan assets at beginning of period 103,047 101,929 — — Actual return on plan assets (17,970) 6,814 — — Employer contributions — — 916 903 Benefits paid (3,422) (5,556) (916) (903) Administrative expenses (102) (140) — — Fair value of plan assets at end of period 81,553 103,047 — — Funded (unfunded) status at end of period (1) $14,897 $13,639 ($13,562) ($17,717) (1) Funded status of the qualified pension plan is included in other assets in the Consolidated Balance Sheets. Unfunded status of the non-qualified retirement plans is included in other liabilities in the Consolidated Balance Sheets. The non-qualified retirement plans provide for the designation of assets in rabbi trusts. Securities available for sale and other short-term investments designated for this purpose, with the carrying value of $14.0 million and $16.7 million are included in the Consolidated Balance Sheets at December 31, 2022 and 2021, respectively.

Assumptions The following table presents the measurement date and weighted-average assumptions used to determine benefit obligations at December 31, 2022 and 2021: Qualified Non-Qualified Retirement Plans 2022 2021 2022 2021 Measurement date Dec 31, 2022 Dec 31, 2021 Dec 31, 2022 Dec 31, 2021 Discount rate 5.54 % 3.00 % 5.50 % 2.90 % Rate of compensation increase 5.00 3.75 5.00 3.75 The following table presents the measurement date and weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31, 2022, 2021 and 2020: Qualified Pension Plan Non-Qualified Retirement Plans 2022 2021 2020 2022 2021 2020 Measurement date Dec 31, 2021 Dec 31, 2020 Dec 31, 2019 Dec 31, 2021 Dec 31, 2020 Dec 31, 2019 Equivalent single discount rate for benefit obligations 3.00 % 2.71 % 3.42 % 2.89 % 2.51 % 3.30 % Equivalent single discount rate for service cost 3.11 2.86 3.54 3.16 2.94 3.62 Equivalent single discount rate for interest cost 2.67 2.16 3.07 2.48 1.97 2.93 Expected long-term return on plan assets 5.25 5.75 5.75 N/A N/A N/A Rate of compensation increase 3.75 3.75 3.75 3.75 3.75 3.75 The expected long-term rate of return on plan assets is based on what the Corporation believes is realistically achievable based on the types of assets held by the plan and the plan’s investment practices. The assumption is updated annually, taking into account the asset allocation, historical asset return trends on the types of assets held and the current and expected economic conditions. Decreases in the long-term rate of return assumption on plan assets increase pension costs and, in general, may increase the requirement to make funding contributions to the plans. Increases in the long-term rate of return on plan assets have the opposite effect. The discount rate assumption for defined benefit pension plans is reset on the measurement date. Discount rates are selected for each plan by matching expected future benefit payments stream to a yield curve based on a selection of high-quality fixed-income debt securities. Decreases in discount rates increase the present value of pension obligations and increase our pension costs, while increases in discount rates have the opposite effect. The "spot rate approach" was utilized in the calculation of interest and service cost. The spot rate approach applies separate discount rates for each projected benefit payment in the calculation of interest and service cost. This approach provides a more precise measurement of service and interest cost by improving the correlation between projected benefit cash flows and their corresponding spot rates. Plan Assets The following tables present the fair values of the qualified pension plan’s assets: (Dollars in thousands) Fair Value Measurements Using Fair Value December 31, 2022 Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $8,438 $— $— $8,438 Obligations of U.S. government-sponsored enterprises — 42,601 — 42,601 Obligations of states and political subdivisions — 1,728 — 1,728 Corporate bonds — 4,854 — 4,854 Mutual funds 23,932 — — 23,932 Total plan assets $32,370 $49,183 $— $81,553 (Dollars in thousands) Fair Value Measurements Using Fair Value December 31, 2021 Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $7,532 $— $— $7,532 Obligations of U.S. government-sponsored enterprises — 47,485 — 47,485 Obligations of states and political subdivisions — 2,233 — 2,233 Corporate bonds — 6,636 — 6,636 Common stocks 16,565 — — 16,565 Mutual funds 22,596 — — 22,596 Total plan assets $46,693 $56,354 $— $103,047 The qualified pension plan uses fair value measurements to record fair value adjustments to the securities held in its investment portfolio. When available, the qualified pension plan uses quoted market prices to determine the fair value of securities; such items are classified as Level 1. This category includes cash and cash equivalents, as well as common stocks and mutual funds which are exchange-traded. Level 2 securities in the qualified pension plan include debt securities with quoted prices, which are traded less frequently than exchange-traded instruments, whose values are determined using matrix pricing with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category includes obligations of U.S. government-sponsored enterprises, obligations of states and political subdivisions and corporate bonds. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities may be classified as Level 3. As of December 31, 2022 and 2021, the qualified pension plan did not have any securities in the Level 3 category. The following table presents the asset allocations of the qualified pension plan, by asset category: December 31, 2022 2021 Asset Category: Cash and cash equivalents 10.3 % 7.3 % Fixed income securities (1) 60.3 54.7 Equity securities (2) 29.4 38.0 Total 100.0 % 100.0 % (1) Includes obligations of U.S. government agencies and U.S. government-sponsored enterprises, obligations of states and political subdivisions and corporate bonds. (2) Includes mutual funds at December 31, 2022 and common stocks and mutual funds at December 31, 2021. The assets of the qualified defined benefit pension plan trust are managed to ensure that all present and future benefit obligations are met as they come due. It seeks to achieve this goal while trying to mitigate volatility in plan funded status, contributions and expense by aligning the characteristics of the plan assets to that of the plan liabilities. The qualified pension plan is well-funded and will become frozen at December 31, 2023, at which point all future benefit accruals will cease. Our investment approach takes these factors into consideration, and as such we have been increasing our allocation to lower-risk fixed income securities and reducing our allocation to higher-risk equity securities. Cash inflow is typically composed of investment income from portfolio holdings and employer contributions, while cash outflow is for the purpose of paying plan benefits and certain plan expenses. As early as possible each year, the trustee is advised of the projected schedule of employer contributions and estimations of benefit payments. Cash Flows Contributions The Code permits flexibility in plan contributions so that normally a range of contributions is possible. The Corporation does not expect to make a contribution to the qualified pension plan in 2023. In addition, the Corporation expects to contribute $904 thousand in benefit payments to the non-qualified retirement plans in 2023. Estimated Future Benefit Payments The following table presents the benefit payments, which reflect expected future service, as appropriate, expected to be paid: (Dollars in thousands) Qualified Non-Qualified Years ending December 31, 2023 $2,870 $904 2024 3,243 892 2025 3,553 899 2026 3,888 935 2027 4,169 951 2028 and thereafter 23,832 4,870 401(k) Plan The Corporation’s 401(k) Plan provides a match up to a maximum of 3% of employee contributions for substantially all employees. In addition, substantially all employees hired after September 30, 2007, who are ineligible for participation in the qualified defined benefit pension plan, receive a non-elective employer contribution of 4% of compensation. Total employer matching contributions under this plan amounted to $3.2 million, $3.0 million and $2.8 million in 2022, 2021 and 2020, respectively. Deferred Compensation Plan The Amended and Restated Nonqualified Deferred Compensation Plan provides supplemental retirement and tax benefits to directors and certain officers. The plan is funded primarily through pre-tax contributions made by the participants. The assets and liabilities of the Deferred Compensation Plan are recorded at fair value in the Consolidated Balance Sheets. The participants in the plan bear the risk of market fluctuations of the underlying assets. The accrued liability related to this plan amounted to $18.7 million and $21.2 million, respectively, at December 31, 2022 and 2021, and is included in other liabilities on the accompanying Consolidated Balance Sheets. The corresponding invested assets are reported in other assets in the Consolidated Balance Sheets.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation Arrangements	Share-Based Compensation Arrangements The Corporation’s equity compensation plans include the 2003 Stock Incentive Plan, the 2013 Stock Option and Incentive Plan and the 2022 Long Term Incentive Plan, which have been approved by the Corporation’s Board of Directors and shareholders. Following shareholder approval of the 2022 Long Term Incentive Plan on April 26, 2022, awards are being granted only from the 2022 Long Term Incentive Plan. The maximum number of shares of common stock that may be issued under the 2022 Long Term Incentive Plan is 600,000 and is subject to adjustment in accordance with the terms of this plan. The types of permitted equity awards under the 2022 Long Term Incentive Plan include stock options (both incentive and non-qualified options), stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, cash-based awards, and dividend equivalent rights. See Item 12 for additional information regarding the equity compensation plans. Reserved Shares As of December 31, 2022, a total of 1,438,109 common stock shares were reserved for issuance under the 2003 Stock Incentive Plan, 2013 Stock Option and Incentive Plan and 2022 Long Term Incentive Plan. Share-based Compensation Expense The following table presents share-based compensation expense and the related income tax benefits recognized in the Consolidated Statements of Income for stock options, restricted stock units and performance share units: (Dollars in thousands) Years ended December 31, 2022 2021 2020 Share-based compensation expense $3,247 $3,316 $3,766 Related income tax benefits (1) $857 $978 $801 (1) Includes $78 thousand and $182 thousand, respectively, of excess tax benefits recognized upon the settlement of share-based compensation awards in 2022 and 2021. Includes $103 thousand of excess tax expenses recognized upon the settlement of share-based compensation awards in 2020. As of December 31, 2022, there was $5.1 million of total unrecognized compensation cost related to share-based compensation arrangements, including stock options, restricted stock units and performance share units granted under the Plans. That cost is expected to be recognized over a weighted average period of 1.9 years. Stock Options The exercise price of each stock option may not be less than the fair market value of the Bancorp’s common stock on the date of grant, and options shall have a term of no more than ten years. Stock options are designated as either non-qualified or incentive stock options. For the years ended 2022, 2021 and 2020, all stock options granted by the Corporation were designated as non-qualified stock options. Washington Trust uses historical data to estimate stock option exercise and employee departure behavior in the option-pricing model. The expected term of options granted was derived from the output of the option valuation model and represents the period of time that options granted are expected to be outstanding. Expected volatility was based on historical volatility of Washington Trust shares. The risk-free rate for periods within the contractual life of the stock option was based on the U.S. Treasury yield curve in effect at the date of grant. The following presents the assumptions used in determining the grant date fair value of the stock option awards granted to certain key employees: 2022 2021 2020 Options granted 57,700 53,700 81,530 Cliff vesting period (years) 3 3 3 Expected term (years) 6.5 6.5 6.5 Expected dividend yield 3.90 % 3.80 % 3.69 % Weighted average expected volatility 31.67 % 31.50 % 29.89 % Weighted average risk-free interest rate 4.15 % 1.41 % 0.46 % Weighted average grant-date fair value $12.01 $11.10 $5.75 The following table presents a summary of stock options outstanding as of and for the year ended December 31, 2022: Number of Stock Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Aggregate Intrinsic Value (000’s) Beginning of period 322,140 $45.95 Granted 57,700 48.50 Exercised (7,950) 30.67 Forfeited or expired — — End of period 371,890 $46.67 6.95 $1,514 Options exercisable at end of period 186,640 $49.54 5.20 $410 The total intrinsic value is the amount by which the fair value of the underlying stock exceeds the exercise price of an option on the exercise date.

Segment Reporting [Abstract]
Business Segments	Business Segments The Corporation manages its operations through two reportable business segments, consisting of Commercial Banking and Wealth Management Services. Management uses an allocation methodology to allocate income and expenses to the business lines. Direct activities are assigned to the appropriate business segment to which the activity relates. Indirect activities, such as corporate, technology and other support functions, are allocated to business segments primarily based upon full-time equivalent employee computations. Commercial Banking The Commercial Banking segment includes commercial, residential and consumer lending activities; mortgage banking activities; deposit generation; cash management activities; banking activities, including customer support and the operation of ATMs, telephone banking, internet banking and mobile banking services; as well as investment portfolio and wholesale funding activities. Wealth Management Services The Wealth Management Services segment includes investment management; holistic financial planning services; personal trust and estate services, including services as trustee, personal representative, custodian and guardian; settlement of decedents’ estates; and institutional trust services, including custody and fiduciary services.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Financial Instruments with Off-Balance Risk The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers and to manage the Corporation’s exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, standby letters of credit, mortgage loan commitments, loan related derivative contracts and interest rate risk management contracts. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the Consolidated Balance Sheets. The contract or notional amounts of these instruments reflect the extent of involvement the Corporation has in particular classes of financial instruments. Financial Instruments Whose Contract Amounts Represent Credit Risk (Unfunded Commitments) Commitments to Extend Credit Commitments to extend credit are agreements to lend to a customer as long as there are no violations of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since some of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements. Each borrower’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained is based on management’s credit evaluation of the borrower. Standby Letters of Credit Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. These standby letters of credit are primarily issued to support the financing needs of the Bank’s commercial customers. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The collateral supporting those commitments is essentially the same as for other commitments. Most standby letters of credit extend for one year. At December 31, 2022 and 2021, there were no liabilities to beneficiaries resulting from standby letters of credit. Should the Corporation be required to make payments to the beneficiary, repayment from the customer to the Corporation is required. Financial Instruments Whose Notional Amounts Exceed the Amount of Credit Risk Mortgage Loan Commitments Interest rate lock commitments are extended to borrowers and relate to the origination of mortgage loans held for sale. To mitigate the interest rate risk and pricing risk associated with these rate locks and mortgage loans held for sale, the Corporation enters into forward sale commitments. Both interest rate lock commitments and forward sale commitments are derivative financial instruments. Loan Related Derivative Contracts The Corporation’s credit policies with respect to interest rate contracts with commercial borrowers are similar to those used for loans. The interest rate contracts with other counterparties are generally subject to bilateral collateralization terms. Interest Rate Risk Management Contracts The Corporation’s interest rate risk management contracts consist of interest rate swap agreements in which the Corporation and another party agree to exchange interest payments (e.g., fixed-rate for variable-rate payments) computed on a notional principal amount. The credit risk associated with these transactions is the risk of default by the counterparty. To minimize this risk, the Corporation enters into interest rate agreements only with highly rated counterparties that management believes to be creditworthy. The following table presents the contractual and notional amounts of financial instruments with off-balance sheet risk: (Dollars in thousands) December 31, 2022 2021 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $1,308,873 $1,006,620 Standby letters of credit 9,028 11,844 Financial instruments whose notional amounts exceed the amount of credit risk: Mortgage loan commitments: Interest rate lock commitments 12,201 49,800 Forward sale commitments 23,150 103,626 Loan related derivative contracts: Interest rate contracts with customers 935,099 1,022,388 Mirror interest rate contracts with counterparties 935,099 1,022,388 Risk participation-in agreements 221,247 163,207 Interest rate risk management contracts: Interest rate swaps 320,000 320,000 See Note 9 for additional disclosure pertaining to derivative financial instruments. ACL on Unfunded Commitments The ACL on unfunded commitments is management’s estimate of expected lifetime credit losses over the expected contractual term in which the Corporation is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Corporation. Unfunded commitments for home equity lines of credit and commercial demand loans are considered unconditionally cancellable for regulatory capital purposes and, therefore, are excluded from the calculation to estimate the ACL on unfunded commitments. For each portfolio, estimated loss rates and funding factors are applied to the corresponding balance of unfunded commitments. The estimated loss rates applied to unfunded commitments are the same quantitative and qualitative loss rates applied to the corresponding on-balance sheet amounts in determining the ACL on loans. The estimated funding factor applied to unfunded commitments represents the likelihood that the funding will occur and is based upon the Corporation’s average historical utilization rate for each portfolio. The activity in the ACL on unfunded commitments for the year ended December 31, 2022 is presented below: (Dollars in thousands) Commercial Consumer CRE C&I Total Commercial Residential Real Estate Home Equity Other Total Consumer Total Beginning Balance $1,267 $816 $2,083 $62 $— $16 $16 $2,161 Provision (31) 172 141 (12) — — — 129 Ending Balance $1,236 $988 $2,224 $50 $— $16 $16 $2,290 The activity in the ACL on unfunded commitments for the year ended December 31, 2021 is presented below: (Dollars in thousands) Commercial Consumer CRE C&I Total Commercial Residential Real Estate Home Equity Other Total Consumer Total Beginning Balance $907 $1,402 $2,309 $54 $— $19 $19 $2,382 Provision 360 (586) (226) 8 — (3) (3) (221) Ending Balance $1,267 $816 $2,083 $62 $— $16 $16 $2,161 Other Contingencies Litigation The Corporation is involved in various claims and legal proceedings arising out of the ordinary course of business. Management is of the opinion, based on its review with counsel of the development of such matters to date, that the ultimate disposition of such matters will not materially affect the consolidated balance sheets or statements of income of the Corporation. Other When selling a residential real estate mortgage loan or acting as originating agent on behalf of a third party, Washington Trust generally makes various representations and warranties. The specific representations and warranties depend on the nature of the transaction and the requirements of the buyer. Contractual liability may arise when the representations and warranties are breached. In the event of a breach of these representations and warranties, Washington Trust may be required to either repurchase the residential real estate mortgage loan (generally at unpaid principal balance plus accrued interest) with the identified defects or indemnify (“make-whole”) the investor for its losses. In the case of a repurchase, the Corporation will bear any subsequent credit loss on the residential real estate mortgage loan. Washington Trust has experienced an insignificant number of repurchase demands over a period of many years. As of December 31, 2022 and 2021, the carrying value of loans repurchased due to representation and warranty claims was $1.0 million and $1.4 million, respectively. Washington Trust has recorded a reserve for its exposure to losses for premium recapture and the obligation to indemnify or repurchase previously sold residential real estate mortgage loans. The reserve balance amounted to $265 thousand and $275 thousand at December 31, 2022 and 2021, respectively, and is included in other liabilities in the Consolidated Balance Sheets. Any change in the estimate is recorded in mortgage banking revenues in the Consolidated Statements of Income.

Accounting Policies [Abstract]
Nature of Operations	Nature of Operations The Bancorp is a publicly-owned registered bank holding company that has elected to be a financial holding company. The Bancorp’s principal subsidiary is the Bank, a Rhode Island chartered financial institution founded in 1800. The Bank is the oldest community bank in the nation and the largest state-chartered bank headquartered in Rhode Island. Washington Trust offers a full range of financial services, including commercial, residential and consumer lending, retail and commercial deposit products, and wealth management and trust services through its offices in Rhode Island, Massachusetts and Connecticut.
Basis of Presentation	Basis of Presentation The accounting and reporting policies of Washington Trust conform to GAAP and to general practices of the banking industry. The consolidated financial statements include the accounts of the Bancorp and its wholly-owned subsidiaries, except subsidiaries that are not deemed necessary to be consolidated. Intercompany balances and transactions have been eliminated in consolidation. The Bancorp owns the common stock of two capital trusts, which have issued trust preferred securities. These capital trusts are variable interest entities in which the Bancorp is not the primary beneficiary and, therefore, are not consolidated. The capital trust’s only assets are junior subordinated debentures issued by the Bancorp, which were acquired by the capital trusts using the proceeds from the issuance of the trust preferred securities and common stock. The Bancorp’s equity interest in the capital trusts, which is classified in other assets, and the junior subordinated debentures are included in the Consolidated Balance Sheets. Interest expense on the junior subordinated debentures is included in the Consolidated Statements of Income. Reclassification Certain previously reported amounts have been reclassified to conform to the current year’s presentation.
Use of Estimates	Use of Estimates In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ from those estimates. Management considers the ACL on loans to be a material estimate that is particularly susceptible to change.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents, as referenced in the accompanying Consolidated Statements of Cash Flows, consists of cash and due from banks and short-term investments. Cash and due from Banks Cash and due from banks includes cash on hand, cash items in process of collection, cash on deposit at the FRBB and other correspondent banks, as well as cash pledged to derivative counterparties. Cash on deposit includes interest-bearing deposits held at correspondent banks of $65.8 million and $128.3 million, respectively, at December 31, 2022 and 2021. Cash collateral pledged to derivative counterparties represents restricted cash balances. See Note 9 for additional disclosure regarding cash collateral pledged to derivative counterparties. Short-term Investments Short-term investments consist of highly liquid investments with a maturity date of three months or less when purchased and are considered to be cash equivalents. The Corporation’s short-term investments may be composed of overnight federal funds sold, securities purchased under resale agreements, money market mutual funds and U.S. Treasury bills.
Securities	Securities Management determines the appropriate classification of securities at the time of purchase. Investments in debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and carried at amortized cost. Securities not classified as held to maturity are classified as available for sale. Securities available for sale consist of debt securities that are available for sale to respond to changes in market interest rates, liquidity needs, changes in funding sources and other similar factors. These assets are specifically identified and are carried at fair value. Changes in fair value of available for sale securities, net of applicable income taxes, are reported as a separate component of shareholders’ equity. Washington Trust does not currently have securities designated as held to maturity and also does not maintain a trading portfolio. Premiums and discounts are amortized and accreted over the term of the securities on a method that approximates the level yield method. The amortization and accretion is included in interest income on securities. Interest income is recognized when earned. Realized gains or losses from sales of securities are recorded on the trade date and are determined using the specific identification method. The fair values of securities may be based on either quoted market prices or third-party pricing services. The Corporation excludes accrued interest from the amortized cost basis of debt securities and reports accrued interest in other assets in the Consolidated Balance Sheets. The Corporation also excludes accrued interest from the estimate of credit losses on debt securities. 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 as of December 31, 2022 and 2021 and, therefore there was no accrued interest related to debt securities reversed against interest income for 2022 and 2021. Allowance for Credit Losses on Securities For available for sale debt securities in an unrealized loss position, management first assesses whether the Corporation intends to sell, or if it is likely that the Corporation will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through a provision for credit losses charge to earnings. For debt securities available for sale that do not meet either of these criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers both quantitative and qualitative factors. A substantial portion of available for sale debt securities held by the Corporation are obligations issued by U.S. government agency and U.S. government-sponsored enterprises, including mortgage-backed securities. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies and have a long history of no credit losses. For these securities, management takes into consideration the long history of no credit losses and other factors to assess the risk of nonpayment even if the U.S. government were to default. As such, the Corporation utilized a zero credit loss estimate for these securities. For available for sale debt securities that are not guaranteed by U.S. government agencies and U.S. government-sponsored enterprises, such as individual name issuer trust preferred debt securities and corporate bonds, management utilizes a third-party credit modeling tool based on observable market data, which assists management in identifying any potential credit risk associated with these available for sale debt securities. This model estimates probability of default, loss given default and exposure at default for each security. In addition, qualitative factors are also considered, including the extent to which fair value is less than amortized cost, changes to the credit rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If a credit loss exists based on the results of this assessment, an ACL (contra asset) 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 considered market-related and is recognized in other comprehensive income, net of taxes. Changes in the ACL on available for sale debt securities are recorded as provision for credit losses. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met.

Mortgage Loans Held for Sale	Mortgage Loans Held for Sale Residential real estate mortgage loans originated and intended for sale in the secondary market are classified as held for sale. ASC 825, “Financial Instruments” allows for the irrevocable option to elect fair value accounting for the initial and subsequent measurement for certain financial assets and liabilities on a contract-by-contract basis that may otherwise not be required to be measured at fair value under other accounting standards. The Corporation has elected the fair value option for mortgage loans held for sale in order to better match changes in fair values of the loans with changes in the fair value of the derivative forward sale commitment contracts used to economically hedge them. Changes in the fair value of mortgage loans held for sale accounted for under the fair value option are included in mortgage banking revenues. Gains and losses on residential loan sales are recognized at the time of sale and are included in mortgage banking revenues. Upfront fees and costs related to mortgage loans held for sale for which the fair value option was elected are recognized in mortgage banking revenues as received / incurred and are not deferred. Commissions received on mortgage loans brokered to various investors are recognized when received and included in mortgage banking revenues.
Loan Servicing Rights	Loan Servicing Rights When residential real estate mortgage loans held for sale are sold with servicing retained, mortgage servicing right assets are recognized as separate assets. Mortgage servicing rights are originally recorded at fair value. Fair value is based on a valuation model that incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, ancillary income, prepayment speeds, and default rates and losses. Mortgage servicing rights are included in other assets and are amortized as an offset to mortgage banking revenues over the period of estimated net servicing income. Mortgage servicing rights are periodically evaluated for impairment based on their fair value. Impairment is measured on an aggregated basis by stratifying the rights based on homogeneous characteristics such as note rate and loan type. The fair value is estimated based on the present value of expected cash flows, incorporating assumptions for discount rate, prepayment speed and servicing cost. Any impairment is recognized through a valuation allowance and as a reduction to mortgage banking revenues.
Loans	Loans Portfolio Loans Loans are carried at the principal amount outstanding, adjusted by partial charge-offs and net of unamortized deferred loan origination fees and costs. Interest income is accrued on a level yield basis based upon principal amounts outstanding, except for loans on nonaccrual status. Deferred loan origination fees and costs are amortized as an adjustment to yield over the term of the related loans. For purchased loans, which did not show signs of credit deterioration at the time of purchase, interest income is also accrued on a level yield basis based upon principal amounts outstanding and is then further adjusted by accretion of any discount or amortization of any premium associated with the loans. Nonaccrual Loans Loans, with the exception of certain well-secured loans that are in the process of collection, are placed on nonaccrual status and interest recognition is suspended when such loans are 90 days or more overdue with respect to principal and/or interest, or sooner if considered appropriate by management. Well-secured loans are permitted to remain on accrual status provided that full collection of principal and interest is assured and the loan is in the process of collection. Loans are also placed on nonaccrual status when, in the opinion of management, full collection of principal and interest is doubtful. When loans are placed on nonaccrual status, interest previously accrued but not collected is reversed against current period income. Subsequent interest payments received on nonaccrual loans are applied to the outstanding principal balance of the loan or recognized as interest income depending on management’s assessment of the ultimate collectability of the loan. Loans are removed from nonaccrual status when they have been current as to principal and interest for a period of time, the borrower has demonstrated an ability to comply with repayment terms, and when, in management’s opinion, the loans are considered to be fully collectible. Troubled Debt Restructured Loans A loan that has been modified or renewed is considered to be a TDR when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower’s benefit that would not otherwise be considered for a borrower or a transaction with similar credit risk characteristics. These concessions may include modifications of the terms of the debt such as deferral of payments, extension of maturity, reduction of principal balance, reduction of the stated interest rate other than normal market rate adjustments, or a combination of these concessions. Debt may be bifurcated with separate terms for each tranche of the restructured debt. Restructuring of a loan in lieu of aggressively enforcing the collection of the loan may benefit the Corporation by increasing the ultimate probability of collection. TDRs are classified as accruing or non-accruing based on management’s assessment of the collectability of the loan. Loans that are already on nonaccrual status at the time of the restructuring generally remain on nonaccrual status for approximately six months before management considers such loans for return to accruing status. Accruing restructured loans are placed into nonaccrual status if and when the borrower fails to comply with the restructured terms and management deems it unlikely that the borrower will return to a status of compliance in the near term and full collection of principal and interest is in doubt. TDRs are reported as such for at least one year from the date of the restructuring. In years after the restructuring, TDRs are removed from this classification if the restructuring did not involve a below-market rate concession and the loan is performing in accordance with their modified contractual terms for a reasonable period of time. The Corporation elected to account for eligible loan modifications under Section 4013 of the CARES Act, as amended by the CRRSA Act. Eligible loan modifications from March 1, 2020 through January 1, 2022 made in response to the COVID-19 pandemic were not required to be classified as TDRs. The vast majority of the loan payment deferral modifications or “deferments” made qualified as eligible loans modifications and were not classified as TDRs. All of these loans with qualified deferments exited their payment deferral period prior to March 31, 2022. Individually Analyzed Loans Individually analyzed loans are individually assessed for credit impairment and include nonaccrual commercial loans, reasonably expected TDRs, executed TDRs, and certain other loans based on the underlying risk characteristics and the discretion of management to individually analyze such loans. A TDR is considered reasonably expected to occur no later than the point when management concludes that modification is the best course of action and it is at least reasonably possible that the troubled borrower will accept some form of concession to avoid a default.
Allowance for Credit Losses on Loans	Allowance for Credit Losses on Loans The ACL on loans is established through a provision for credit losses recognized in the Consolidated Statements of Income. The ACL on loans is also increased by recoveries of amounts previously charged-off and is reduced by charge-offs on loans. Loan charge-offs are recognized when management believes the collectability of the principal balance outstanding is unlikely. Full or partial charge-offs on collateral dependent individually analyzed loans are generally recognized when the collateral is deemed to be insufficient to support the carrying value of the loan. The ACL on loans is management’s estimate of expected lifetime credit losses on loans carried at amortized cost. The Corporation made an accounting policy election to exclude accrued interest from the amortized cost basis of loans and reports accrued interest in other assets in the Consolidated Balance Sheets. The Corporation also excludes accrued interest from the estimate of credit losses on loans. The level of the ACL on loans is based on management’s ongoing review of all relevant information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the calculation of loss given default and the estimation of expected credit losses. As discussed further below, adjustments to historical information are made for differences in specific risk characteristics, such as differences in underwriting standards, portfolio mix, delinquency level, or term, as well as for changes in environmental conditions, that may not be reflected in historical loss rates. Management employs a process and methodology to estimate the ACL on loans that evaluates both quantitative and qualitative factors. In accordance with the Corporation’s ACL policy, the methodology is reviewed no less than annually. The methodology for evaluating quantitative factors consists of two basic components. The first component involves pooling loans into portfolio segments for loans that share similar risk characteristics. Pooled loan portfolio segments include CRE (including a commercial construction sub-segment), C&I (including a PPP sub-segment), residential real estate, home equity and other consumer loans. The second component involves identifying individually analyzed loans that do not share similar risk characteristics with loans that are pooled into portfolio segments. Individually analyzed loans include nonaccrual commercial loans, reasonably expected TDRs and executed TDRs, as well as certain other loans based on the underlying risk characteristics and the discretion of management to individually analyze such loans. For loans that are individually analyzed, the ACL is measured using a DCF method based upon the loan’s contractual effective interest rate, or at the loan’s observable market price, or, if the loan is collateral dependent, at the fair value of the collateral. Factors management considers when measuring the extent of expected credit loss include payment status, collateral value, borrower financial condition, guarantor support and the probability of collecting scheduled principal and interest payments when due. For collateral dependent loans for which repayment is to be provided substantially through the sale of the collateral, management adjusts the fair value for estimated costs to sell. For collateral dependent loans for which repayment is to be provided substantially through the operation of the collateral, such as accruing TDRs, estimated costs to sell are not incorporated into the measurement. Management may also adjust appraised values to reflect estimated market value declines or apply other discounts to appraised values for unobservable factors resulting from its knowledge of circumstances associated with the collateral. For pooled loans, the Corporation utilizes a DCF methodology to estimate credit losses over the expected life of the loan. The life of the loan excludes expected extensions, renewals and modifications, unless the extension or renewal options are included in the original or modified contract terms and not unconditionally cancellable by the Corporation. The methodology incorporates a probability of default and loss given default framework. Default triggers include the loan has become past due by 90 or more days, a charge-off has occurred, the loan has been placed on nonaccrual status, the loan has been modified in a TDR or the loan is risk-rated as special mention or classified. Loss given default is estimated based on historical credit loss experience. Probability of default is estimated utilizing a regression model that incorporates econometric factors. Econometric factors are selected based on the correlation of the factor to historical credit losses for each portfolio segment. The following table summarizes the econometric factors utilized for each loan portfolio segment as of the dates indicated: Econometric Factors Loan portfolio segment At December 31, 2022 At December 31, 2021 CRE NUR & GDP NUR & GDP C&I NUR & GDP NUR Residential real estate NUR & HPI NUR & HPI Home equity NUR & HPI NUR & HPI Other consumer GDP NUR & GDP To estimate the probability of default, the model utilizes forecasted econometric factors over a one-year reasonable and supportable forecast period. After the forecast period, the model reverts to the historical mean of the respective econometric factor and the associated probability of default on a straight-line basis over a one-year reversion period. The DCF methodology combines the probability of default, the loss given default, prepayment speeds and the remaining life of the loan to estimate a reserve for each loan. The sum of all the loan level reserves are aggregated for each portfolio segment and a loss rate factor is derived. Quantitative loss factors are also supplemented by certain qualitative risk factors reflecting management’s view of how losses may vary from those represented by quantitative loss rates. These qualitative risk factors include: 1) changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; 2) changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; 3) changes in the nature and volume of the portfolio and in the terms of loans; 4) changes in the experience, ability, and depth of lending management and other relevant staff; 5) changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or rated loans; 6) changes in the quality of the institution’s credit review system; 7) changes in the value of underlying collateral for collateral dependent loans; 8) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and 9) the effect of other external factors such as legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio. Qualitative loss factors are applied to each portfolio segment with the range of amounts determined by historical loan charge-offs of a peer group of similar-sized regional banks. Because the methodology is based upon historical experience and trends, current economic data, reasonable and supportable forecasts, as well as management’s judgment, factors may arise that result in different estimations. Deteriorating conditions or assumptions could lead to further increases in the ACL on loans, conversely improving conditions or assumptions could lead to further reductions in the ACL on loans. In addition, various regulatory agencies periodically review the ACL on loans. Such agencies may require additions to the allowance based on their judgments about information available to them at the time of their examination. The ACL on loans is an estimate, and ultimate losses may vary from management’s estimate.
Allowance for Credit Losses on Unfunded Commitments	Allowance for Credit Losses on Unfunded Commitments The ACL on unfunded commitments is management’s estimate of expected lifetime credit losses over the expected contractual term in which the Corporation is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Corporation. Unfunded commitments for home equity lines of credit and commercial demand loans are considered unconditionally cancellable for regulatory capital purposes and, therefore, are excluded from the calculation to estimate the ACL on unfunded commitments. For each portfolio, estimated loss rates and funding factors are applied to the corresponding balance of unfunded commitments. The estimated loss rates applied to unfunded commitments are the same quantitative and qualitative loss rates applied to the corresponding on-balance sheet amounts in determining the ACL on loans. The estimated funding factor applied to unfunded commitments represents the likelihood that the funding will occur and is based upon the Corporation’s average historical utilization rate for each portfolio. The ACL on unfunded commitments is included in other liabilities in the Consolidated Balance Sheets. The ACL on unfunded commitments is adjusted through a provision for credit losses recognized in the Consolidated Statements of Income.
Premises and Equipment	Premises and Equipment Land is carried at cost. Premises and equipment are carried at cost less accumulated depreciation. Depreciation for financial reporting purposes is calculated on the straight-line method over the estimated useful lives of assets. For leasehold improvements, the estimated useful life is the shorter of the expected lease term or the estimated useful life of the improvement. Expected lease terms include lease renewal options to the extent that the exercise of such renewals is reasonably assured. The estimated useful lives of premises and improvements range from 5 to 40 years. For furniture, fixtures and equipment, the estimated useful lives range from 3 to 20 years. Repairs and maintenance costs are charged to noninterest expense as incurred.
Leases	Leases The Corporation has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. Operating leases are recorded on the balance sheet, through the recognition of an operating lease ROU asset and an operating lease liability at the commencement date of the new lease. ROU assets represent a right to use an underlying asset for the contractual lease term. Operating lease liabilities represent an obligation to make lease payments arising from the lease. The Corporation’s leases do not provide an implicit interest rate, therefore the Corporation uses its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine the present value of operating lease liabilities. The Corporation’s operating lease agreements contain both lease and non-lease components, which are generally accounted for separately. The Corporation’s lease agreements do not contain any residual value guarantees. Operating leases with terms of 12 months or less are included in ROU assets and operating lease liabilities recorded in the Consolidated Balance Sheets. Operating lease terms include options to extend when it is reasonably certain that the Corporation will exercise such options, determined on a lease-by-lease basis. Lease expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease components, such
Bank-Owned Life Insurance	Bank-Owned Life Insurance The investment in BOLI represents the cash surrender value of life insurance policies on the lives of certain employees who have provided positive consent allowing the Bank to be the beneficiary of such policies. Increases in the cash value of the policies, as well as insurance proceeds received, are recorded in noninterest income and are not subject to income taxes. The financial strength of the insurance carrier is reviewed prior to the purchase of BOLI and annually thereafter.
Goodwill and Identifiable Intangible Assets	Goodwill and Identifiable Intangible Assets Goodwill represents the excess of the purchase price over the net fair value of the acquired businesses. Goodwill is not amortized, but is tested for impairment at the reporting unit level (defined as the segment level), at least annually in the fourth quarter or more frequently whenever events or circumstances occur that indicate that it is more-likely-than-not that an impairment loss has occurred. In assessing impairment, the Corporation has the option to perform a qualitative analysis to determine whether the existence of events or circumstances leads to a determination that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount. If, after assessing the totality of such events or circumstances, we determine it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, then we would not be required to perform an impairment test. The quantitative impairment analysis requires a comparison of each reporting unit’s fair value to its carrying value to identify potential impairment. Goodwill impairment exists when a reporting unit’s carrying value of goodwill exceeds its implied fair value. Significant judgment is applied when goodwill is assessed for impairment. This judgment includes, but may not be limited to, the selection of appropriate discount rates, the identification of relevant market comparables and the development of cash flow projections. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weightings that are most representative of fair value. Intangible assets identified in acquisitions consist of advisory contracts. The value attributed to intangible assets was based on the time period over which they are expected to generate economic benefits. Intangible assets are amortized over their estimated lives using a method that approximates the amount of economic benefits that are realized by the Corporation. Intangible assets with definite lives are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. If applicable, the Corporation tests each of the intangibles by comparing the carrying value of the intangible asset to the sum of undiscounted cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its undiscounted cash flows, then an impairment loss would be recognized for the amount by which the carrying amount exceeds its fair value. Impairment would result in a write-down to the estimated fair value based on the anticipated discounted future cash flows. The remaining useful life of the intangible assets that are being amortized is also evaluated to determine whether events and circumstances warrant a revision to the remaining period of amortization.
Property Acquired through Foreclosure or Repossession	Property Acquired through Foreclosure or Repossession Property acquired through foreclosure or repossession is carried at the lower of cost or fair value less estimated costs to sell. Fair value of such assets is determined based on independent appraisals and other relevant factors. Any write-down to fair value at the time of foreclosure or repossession is charged to the ACL on loans. Subsequent to foreclosure or repossession, a valuation allowance is maintained for declines in market value and for estimated selling expenses. Upon sale of foreclosed property, any excess of the carrying value over the sales proceeds is recognized as a loss on sale. Any excess of sales proceeds over the carrying value of the foreclosed property is first applied as a recovery to the valuation allowance, if any, with the remainder being recognized as a gain on sale. Changes to the valuation allowance, expenses associated with ownership of these properties, and gains and losses from their sale are included in other noninterest expense. Loans that are substantively repossessed include only those loans for which the Corporation has obtained control of the collateral, but has not completed legal foreclosure proceedings.
Investment in Real Estate Limited Partnerships	Investments in Real Estate Limited Partnerships The Bank invests in real estate limited partnerships that renovate, own and operate low-income housing complexes. The Bank neither actively participates in the management of nor has a controlling interest in the real estate limited partnerships. The carrying value of such investments is recorded in other assets on the Consolidated Balance Sheets.
Other Equity Investments	Other Equity Investments The Corporation invests in equity investments without readily determinable fair value. Such equity investments are classified within other assets in the Consolidated Balance Sheet. The Corporation has elected to carry equity investments without readily determinable fair value at cost, less impairment, if any, plus or minus changes in observable prices. A qualitative impairment analysis for equity investments without readily determinable fair value is performed quarterly. If the equity investment is deemed to be impaired, an impairment loss is recognized in the amount by which the carrying value of the equity investment exceeds its estimated fair value. The impairment loss is recognized as a reduction of other noninterest income in the Consolidated Statement of Income. An impairment loss can be reversed in a subsequent period if there are observable transactions for the identical or similar investment of the same issuer at an amount that is greater than the carrying value of the investment that was established when the impairment loss was recognized. The reversal of any impairment loss or other changes resulting from observable transactions are recognized in other noninterest income in the Consolidated Statement of Income.
Impairment of Long-Lived Assets Other than Goodwill	Impairment of Long - Lived Assets Other than Goodwill
Transfers and Servicing of Assets and Extinguishments of Liabilities	Transfers and Servicing of Assets and Extinguishments of Liabilities The accounting for transfers and servicing of financial assets and extinguishments of liabilities is based on consistent application of a financial components approach that focuses on control. This approach distinguishes transfers of financial assets that are sales from transfers that are secured borrowings. Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right to pledge or exchange the transferred assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Corporation, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. If a transfer does not meet the criteria for a sale, the transfer is accounted for as a secured borrowing with a pledge of collateral.
Wealth Management AUA	Wealth Management AUA AUA represents assets held in a fiduciary or agency capacity for wealth management clients and are not included in the Consolidated Balance Sheets, as these are not assets of the Corporation.
Revenue from Contracts with Customers	Revenue from Contracts with Customers ASC 606, Revenue from Contracts with Customers, provides a revenue recognition framework for contracts with customers unless those contracts are within the scope of other accounting standards. The Corporation recognizes revenue from contracts with customers by identifying the performance obligations in its contracts, determining the transaction price in the contract, allocating the transaction price to each performance obligation contained within the contract, as applicable, and then recognizing revenue from its contracts with customers when it satisfies its performance obligations . The performance obligations are generally satisfied as services are rendered and can either be satisfied at a point in time or over time. Revenue that is earned at a point in time 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. This includes card interchange fees (fee income related to debit card transactions), certain service charges on deposits accounts such as overdraft charges, ATM fees for customers, stop-payment fees, and certain other income such as wire transfer fees and ATM fees for non-customers. Revenue that is earned over time is generally recognized over the term of the contract as services are performed and performance obligations are satisfied. Such revenue includes wealth management revenues, monthly service charges on deposit accounts and certain other income such as safe deposit box rental fees. In certain cases, other parties are involved with providing services to our customers. If the Corporation is a principal in the transaction (providing services itself or through a third party on its behalf), revenues are reported based on the gross consideration received from the customer and any related expenses are reported gross in noninterest expense. If the Corporation is an agent in the transaction (referring customers to another party to provide services), the Corporation reports its net fee or commission retained as revenue. For certain commissions and incentives, such as those paid to employees in our wealth management services and commercial banking segments in order to obtain customer contracts, contract cost assets are established. The contract cost assets are capitalized and amortized over the estimated useful life that the asset is expected to generate benefits. Contract cost assets are included in other assets in the Consolidated Balance Sheets. The amortization of contract cost assets is recorded within salaries and employee benefits expense in the Consolidated Statements of Income.
Pension Costs	Pension Costs Pension benefits are accounted for using the net periodic benefit cost method, which recognizes the compensation cost of an employee’s pension benefit over that employee’s approximate service period. Pension benefit costs and benefit obligations incorporate various actuarial and other assumptions, including discount rates, mortality, rates of return on plan assets and compensation increases. Management evaluates these assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends when it is appropriate to so do. The effect of modifications to those assumptions is recorded in other comprehensive income (loss) and amortized to net periodic cost over future periods. The service cost component of net periodic benefit cost is recognized within salaries and employee benefits expense in the Consolidated Statements of Income. All other components of net periodic benefit cost are recognized in other noninterest expense in the Consolidated Statements of Income. The funded status of defined benefit pension plans, measured as the difference between the fair value of plan assets and the projected benefit obligation, is recognized in the Consolidated Balance Sheet. The changes in the funded status of the defined benefit plans, including actuarial gains and losses and prior service costs and credits, are recognized in comprehensive income in the year in which the changes occur.
Share-Based Compensation	Share-Based Compensation Share-based compensation plans provide for awards of stock options and other equity incentives, including restricted stock units and performance share units. Compensation expense for awards is recognized over the service period based on the fair value at the date of grant and is included in salaries and employee benefits expense in the Corporation’s Consolidated Statements of Income. Grant date fair value for stock options is estimated using the Black-Scholes option-pricing model. Awards of restricted stock units and performance share units are valued at the fair market value of the Bancorp’s common stock as of the award date. Performance share unit compensation expense is based on the most recent performance assumption available and is adjusted as assumptions change. Forfeitures are recognized when they occur. Vesting of the awards may accelerate or may be subject to proportional vesting if there is a change in control, disability, retirement or death. Vested equity awards are issued from treasury stock, when available, or from authorized but unissued stock. Excess tax benefits (expenses) result when tax return deductions differ from recognized share-based compensation cost that are determined using the grant-date fair value approach for financial statement purposes. Excess tax benefits (expenses) related to the settlement of share-based awards are recorded as a decrease (increase) to income tax expense in the Corporation’s Consolidated Income Statements and are classified in the Consolidated Statements of Cash Flows as an operating activity.
Income Taxes	Income Taxes Income tax expense is determined based on the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to an amount, which is more-likely-than-not to be realizable. Additionally, a liability for unrecognized tax benefits is recorded for uncertain tax positions taken by the Corporation on its tax returns for which there is less than a 50% likelihood of being recognized upon a tax examination. The Corporation records interest related to unrecognized tax benefits in income tax expense. Penalties, if incurred, would be recognized as a component of income tax expense.
Segment Reporting	Segment Reporting The Corporation manages its operations through two reportable business segments, consisting of Commercial Banking and Wealth Management Services. Additional information on the segments is presented in Note 18. Management uses an allocation methodology to allocate income and expenses to the business lines. Direct activities are assigned to the appropriate business segment to which the activity relates. Indirect activities, such as corporate, technology and other support functions, are allocated to business segments primarily based upon full-time equivalent employee computations. Segment reporting results may be restated, when necessary, to reflect changes in organizational structure or allocation methodology. Any changes in estimates and allocations that may affect the reported results of any business segment will not affect the consolidated financial position or results of operations of the Corporation as a whole.
Earnings Per Common Share	Earnings Per Common Share EPS is calculated utilizing the two-class method. The two-class method is an earnings allocation formula that determines earnings per share of each class of stock according to dividends and participation rights in undistributed earnings. Share‑based awards that entitle holders to receive nonforfeitable dividends before vesting are considered participating securities (i.e., restricted stock units awarded under the 2013 Stock Option and Incentive Plan), not subject to performance-based measures. These participating securities are included in the earnings allocation for computing basic earnings per share under this method. Undistributed income is allocated to common shareholders and participating securities under the two-class method based upon the proportion of each to the total weighted average shares available. Under the two-class method, basic EPS is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding. Diluted EPS is computed using the weighted-average number of shares determined for the basic EPS computation plus the dilutive effect on common shares outstanding, using the treasury stock method.
Comprehensive Income	Comprehensive Income Comprehensive income is defined as all changes in equity, except for those resulting from transactions with shareholders. Net income is a component of comprehensive income. All other components are referred to in the aggregate as other comprehensive income (loss). Other comprehensive income (loss) includes the after-tax effect of net changes in the fair value of securities available for sale, net changes in fair value of cash flow hedges and net changes in defined benefit pension plan obligations.
Guarantees	Guarantees Standby letters of credit are considered a guarantee of the Corporation. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. The credit risk involved in issuing standby letters of credit
Derivative Insturments and Hedging Activities	Derivative Instruments and Hedging Activities Derivatives are recognized as either assets or liabilities on the balance sheet and are measured at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and resulting designation. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative are recorded in other comprehensive income (loss) and subsequently reclassified to earnings when gains or losses are realized. For derivatives not designated as hedges, changes in fair value of the derivative instruments are recognized in earnings, in noninterest income. Net accrued interest receivable or payable on derivatives that qualify for hedge accounting are recorded in interest income or interest expense based on the item being hedged. Net accrued interest receivable or payable on derivatives that do not qualify for hedge accounting are reported in noninterest income. When a cash flow hedge is discontinued, but the hedged cash flows or forecasted transaction is still expected to occur, changes in value that were accumulated in other comprehensive income (loss) are amortized or accreted into earnings over the same periods that the hedged transactions will affect earnings.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820, “Fair Value Measurements and Disclosures”, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The required disclosures about fair value measurements have been included in Note 10.
