Significant Accounting Policies [Text Block] SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations

Independent Bank Corp. (the “Company”) is a bank holding company, the principal subsidiary of which is Rockland Trust Company (“Rockland Trust” or the “Bank”). Rockland Trust is a state-chartered commercial bank which provides a variety of banking, investment and financial services through its retail branches, commercial banking centers, investment management offices, and mortgage lending centers located throughout Eastern Massachusetts as well as in Worcester County and Rhode Island. Rockland Trust deposits are insured by the Federal Deposit Insurance Corporation, subject to regulatory limits. The Company’s primary source of income is from providing loans to individuals and small-to-medium sized businesses in its market area. Rockland Trust is a community-oriented commercial bank, and the community banking business is the Company’s only reportable operating segment.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, the Bank and other wholly-owned subsidiaries, except subsidiaries that are not deemed necessary to be consolidated. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under GAAP. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company would consolidate voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, variable interest entities (“VIEs”) are entities that lack one or more of the characteristics of a voting interest entity.  A controlling financial interest in a VIE is present when the Company has both the power and ability to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. 

The Company also owns the common stock of various trusts which have issued trust preferred securities. These trusts are VIEs in which the Company is not the primary beneficiary and, therefore, are not consolidated. The trust's only assets are junior subordinated debentures issued by the Company, which were acquired by the trust using the proceeds from the issuance of the trust preferred securities and common stock. The junior subordinated debentures are included in long-term debt and the Company’s equity interest in the trust is included in other assets in the accompanying Consolidated Balance Sheets. Interest expense on the junior subordinated debentures is reported in interest expense on long-term debt in the accompanying Consolidated Statements of Income.

Reclassification

Certain previously reported amounts have been reclassified to conform to the current year’s presentation, including the following:

the Company reclassified its portfolio of loans secured by owner-occupied commercial real estate to the commercial and industrial loan category to more appropriately reflect the variation in the management and underlying risk profile of such loans compared with investor-owned commercial real estate loans; and

the Company combined the presentation of “Software maintenance” and “Subscriptions” costs into “Software and subscriptions” costs within Non-interest expense within the Consolidated Statements of Income. Previously, “Subscriptions” costs were included within “Other noninterest expenses.”

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting periods. Actual results could vary from these estimates. Material estimates that are particularly susceptible to significant changes in the near-term relate to the determination of the allowance for expected credit losses on loans held for investment, income taxes, valuation and allowance for expected credit losses on investment securities, and the valuation of goodwill and other intangible assets and their respective analyses of impairment.

Concentrations of Credit Risk

The vast majority of the Bank’s lending activities are conducted in New England. The Bank originates commercial and industrial loans, commercial and residential real estate loans, including construction loans, small business loans, home equity loans, and other consumer loans for its portfolio. The Bank tracks concentrations of credit across numerous categories and segments based on aggregate credit exposure, which includes direct, indirect or contingent obligations to a borrower or group of borrowers engaged in one industry and by property type. The Bank considers a concentration to exist when aggregate credit exposure of a category or segment exceeds 25% of the Bank's total risk-based capital (inclusive of Tier 2 capital instruments).

Business Combinations

In accordance with applicable accounting guidance, the Company recognizes assets acquired and liabilities assumed at their respective fair values as of the date of acquisition, with the related transaction costs expensed in the period incurred. The Company may use third party valuation specialists to assist in the determination of fair value of certain assets and liabilities at the acquisition date, including loans, core deposit intangibles and time deposits. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed on the acquisition date, the estimates are inherently uncertain. The allowance for credit losses on purchased credit deteriorated (“PCD”) loans is recognized within business combination accounting. The allowance for credit losses on non-PCD loans is recognized as a provision expense in the same period as the business combination.

Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents may include cash on hand, amounts due from banks, inclusive of interest-earning deposits held at banks, and federal funds sold. Generally, federal funds are sold for up to two week periods.

Securities

Investment securities are classified at the time of purchase as available for sale, held to maturity, trading, or equity. Classification is constantly re-evaluated for consistency with corporate goals and objectives. Trading and equity securities are recorded at fair value with subsequent changes in fair value recorded in earnings. Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity or trading are classified as available for sale and recorded at fair value, with changes in fair value excluded from earnings and reported in other comprehensive income, net of related tax. Purchase premiums and discounts are recognized in interest income, using the interest method, to arrive at periodic interest income at a constant effective yield, thereby reflecting the securities market yield. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Such gains and losses are recognized within non-interest income or non-interest expense within the Consolidated Statements of Income.

Accrued interest receivable balances are excluded from the amortized cost of held to maturity securities and the fair value of available for sale securities and are included within other assets on the Consolidated Balance Sheets. Management has elected not to measure an allowance for credit losses on these balances as the Company employs a timely write-off policy. It is the Company’s policy that a security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent, and interest earned but not collected for a security placed on non-accrual is reversed against interest income.

Allowance for Credit Losses - Available for Sale Securities

The Company’s available for sale securities are carried at fair value and assessed for estimated credit losses in accordance with the current expected credit loss (“CECL” methodology). For available for sale securities in an unrealized loss position, management will first evaluate whether there is intent to sell, or if it is more likely than not that the Company will be required to sell a security prior to anticipated recovery of its amortized cost basis. If either of these criteria are met, the Company will record a write-down of the security’s amortized cost basis to fair value through income. For those available for sale securities which do not meet the intent or requirement to sell criteria, management will evaluate whether the decline in fair value is a result of credit related matters or other factors. In performing this assessment, management considers the
creditworthiness of the issuer including whether the security is guaranteed by the U.S. Federal Government or other government agency, the extent to which fair value is less than amortized cost, and changes in credit rating during the period, among other factors. If this assessment indicates the existence of credit losses, the security will be written down to fair value, as determined by a discounted cash flow analysis. To the extent the estimated cash flows do not support the amortized cost, the deficiency is considered to be due to credit loss and is recognized in earnings.

Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense. Losses are charged against the allowance when the uncollectibility of a security is confirmed, or when either of the aforementioned criteria surrounding intent or requirement to sell have been met.

Allowance for Credit Losses - Held to Maturity Securities

The Company measures expected credit losses on held to maturity securities on a collective basis by major security type in accordance with the CECL methodology. Management classifies the held to maturity portfolio into the following major security types: U.S. Government Agency, U.S. Treasury, Agency Mortgage-Backed Securities, Agency Collateralized Mortgage Obligations, Small Business Administration Pooled Securities, and Single Issuer Trust Preferred Securities. Securities in the Company’s held to maturity portfolio are primarily guaranteed by either the U.S. Federal Government or other government sponsored agencies with a long history of no credit losses. As a result, management has determined these securities to have a zero loss expectation and therefore does not estimate an allowance for credit losses on these securities.

Loans Held for Sale

The Bank may choose to classify new residential real estate mortgage loans as held for sale based on intent, which is determined when loans are underwritten. Loans that are classified as held for sale at the time of origination are accounted for under the fair value option, whereby any changes in fair value relating to loans intended for sale are recorded in earnings and are offset by changes in fair value relating to interest rate lock commitments and forward sales commitments. Gains and losses on residential loan sales (sales proceeds minus carrying amount) are recorded in mortgage banking income. Upfront costs and fees related to items for which the fair value option is elected are recognized in earnings as incurred and are not deferred.

Alternatively, any loans not originated for sale but subsequently transferred from held for investment to held for sale are valued at the lower of cost or fair value on an individual asset basis. Prospectively, any cost amounts in excess of fair value would be recorded as a valuation allowance and recognized as a reduction of other non-interest income.

Loans Held for Investment    

Loans that the Company has the intent and ability to hold until maturity or payoff are carried at amortized cost (net of the allowance for credit losses). Amortized cost is the principal amount outstanding, adjusted by partial charge-offs and net of deferred loan costs or fees. For originated loans, loan fees and certain direct origination costs are deferred and amortized into interest income over the expected term of the loan using the level-yield method.  When a loan is paid off, the unamortized portion is recognized in interest income. Interest income on loans is accrued based upon the daily principal amount outstanding except for loans on nonaccrual status.

 As a general rule, loans 90 days or more past due with respect to principal or interest are classified as nonaccrual loans, or sooner if management considers such action to be prudent. However, loans that are 90 days or more past due may be kept on an accruing status if the loan is well secured and in the process of collection. Income accruals are suspended on all nonaccrual loans in a timely manner and all previously accrued and uncollected interest is reversed against current income. A loan remains on nonaccrual status until it becomes current with respect to principal and interest and remains current for a minimum period of six months, the loan is liquidated, or when the loan is determined to be uncollectible and is charged-off against the allowance for credit losses. When doubt exists as to the collectability of a loan, any payments received are applied to reduce the amortized cost of the loan to the extent necessary to eliminate such doubt. For all loan portfolios, a charge-off occurs when the Company determines that a specific loan, or portion thereof, is uncollectible.  This determination is made based on management’s review of specific facts and circumstances of the individual loan, including assessing the viability of the customer’s business or project as a going concern, the expected cash flows to repay the loan, the value of the collateral and the ability and willingness of any guarantors to perform. 

In the course of resolving problem loans, the Company may choose to modify the contractual terms of certain loans. The Company attempts to work out an alternative payment schedule with the borrower in order to avoid or cure a default. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status and may include adjustments to term extensions, interest rates, other than insignificant payment delays and/or a combination thereof. These
actions are intended to minimize economic loss and avoid foreclosure or repossession of collateral. If such efforts by the Bank do not result in satisfactory performance, the loan is referred to legal counsel, at which time foreclosure proceedings are initiated. At any time prior to a sale of the property at foreclosure, the Bank may terminate foreclosure proceedings if the borrower is able to work out a satisfactory payment plan. Any loans that are modified are reviewed by the Company to determine whether the modification is the direct result of a borrower experiencing financial difficulty, as the Company adopted the accounting and disclosure requirements for loan modifications made to borrowers experiencing financial difficulty and ceased to recognize troubled debt restructurings (“TDRs”) effective January 1, 2023. Prior to this adoption, the Company would classify loans as TDRs in cases where a borrower was experiencing financial difficulty and where the Company made certain concessionary modifications to contractual terms. Modifications included adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations had been effectively discharged through Chapter 7 Bankruptcy and the borrower had not reaffirmed the debt to the Bank, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. Under the previously applicable guidance, loans classified as TDRs would have remained classified as such for the life of the loan, except in limited circumstances, when it was determined that the borrower was performing under the modified terms and the restructuring agreement specified an interest rate greater than or equal to an acceptable market rate for a comparable new loan at the time of the restructuring.

Allowance for Credit Losses - Loans Held for Investment

The allowance for credit losses is established based upon the Company’s current estimate of expected lifetime credit losses on loans measured at amortized cost, also referred to as the CECL methodology. Credit losses are charged against the allowance when management’s assessments confirm that the Company will not collect the full amortized cost basis of a loan. Subsequent recoveries, if any, are credited to the allowance.

Under the CECL methodology, the Company estimates credit losses for financial assets on a collective basis for loans sharing similar risk characteristics using a quantitative model combined with an assessment of certain qualitative factors designed to address forecast risk and model risk inherent in the quantitative model output. The quantitative model utilizes a factor-based approach to estimate expected credit losses using Probability of Default (“PD”), Loss Given Default (“LGD”) and Exposure at Default (“EAD”), which are derived from internal historical default and loss experience. The model estimates expected credit losses using loan level data over the estimated life of the exposure, considering the effect of prepayments. Economic forecasts are incorporated into the estimate over a reasonable and supportable forecast period, beyond which is a reversion to the Company’s historical long-run average. Management has determined a reasonable and supportable period of 12 months, and a straight line reversion period of 6 months, to be appropriate for purposes of estimating expected credit losses. The qualitative risk factors impacting the expected risk of loss within the portfolio include the following:

Lending policies and procedures
Economic and business conditions
Nature and volume of loans
Changes in management
Changes in credit quality
Changes in loan review system
Changes to underlying collateral values
Concentrations of credit risk
Other external factors
Model imprecision

Loans that do not share similar risk characteristics with any pools of assets are subject to individual evaluation and are removed from the collectively assessed pools to avoid double counting. For the loans that are individually evaluated, the Company uses either a discounted cash flow (“DCF”) approach or a fair value of collateral approach. The latter approach is used for loans deemed to be collateral dependent or when foreclosure is probable.

Loan modifications made to borrowers experiencing financial difficulty are evaluated on a collective basis with loans sharing similar risk characteristics in accordance with the CECL methodology. Under previously applicable accounting guidance, the Company determined the amount of allowance for credit losses on TDRs using a discounted cash flow analysis or
a fair value of collateral approach if the loan was determined to be individually evaluated. This change in methodology did not have a material impact on the Company’s allowance for credit loss estimate.

Accrued interest receivable amounts are excluded from balances of loans held at amortized cost and are included within other assets on the Consolidated Balance Sheets. Management has elected not to measure an allowance for credit losses on these amounts as the Company employs a timely write-off policy. Consistent with the Company’s policy for nonaccrual loans, accrued interest receivable is typically written off when loans reach 90 days past due and are placed on nonaccrual status.

Allowance for Credit Losses - Unfunded Lending Commitments

In the ordinary course of business, the Company enters into commitments to extend credit, commercial letters of credit, and standby letters of credit. The allowance for credit losses on these unfunded loan commitments provides for potential exposure inherent with the funding of unused portions on legal commitments that are not unconditionally cancellable by the Company. Management evaluates the need for a reserve on unfunded lending commitments in a manner consistent with loans held for investment. The reserve for unfunded lending commitments is included in other liabilities on the Consolidated Balance Sheets.

Acquired Loans

Loans acquired through purchase or a business combination are recorded at their fair value at the acquisition date. The Company performs an assessment of acquired loans to first determine if such loans have experienced a more than insignificant deterioration in credit quality since their origination and thus should be classified and accounted for as PCD loans. For loans that have not experienced a more than insignificant deterioration in credit quality since origination, referred to as non-PCD loans, the Company records such loans at fair value, with any resulting discount or premium accreted or amortized into interest income over the remaining life of the loan using the interest method. Additionally, upon the purchase or acquisition of non-PCD loans, the Company measures and records a reserve for credit losses based on the Company’s methodology for determining the allowance under CECL. The allowance for non-PCD loans is recorded through a charge to provision for credit losses in the period in which the loans were purchased or acquired.

Acquired loans that are classified as PCD are acquired at fair value, including any resulting discounts or premiums. Discounts and premiums are accreted or amortized into interest income over the remaining life of the loan using the interest method. In contrast to non-PCD loans, the initial allowance for credit losses on PCD loans is established through an adjustment to the acquired loan balance, rather than through a charge to provision for credit losses, in the period in which the loans were acquired. The allowance for PCD loans is determined based upon the Company’s methodology for estimating the allowance under CECL, and is recorded as an adjustment to the acquired loan balance on the date of acquisition. The Company evaluates acquired loans for deterioration in credit quality based on a variety of characteristics, including, but not limited to non-accrual and delinquency status, downgrades in credit quality since origination, loans that have been modified, along with any other factors identified by the Company through its initial analysis of acquired loans which may indicate there has been a more than insignificant deterioration in credit quality since origination. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics, if applicable.

Subsequent to acquisition, the allowances for credit losses for both non-PCD and PCD loans are determined with the use of the Company’s allowance methodology under CECL, in the same manner as all other loans.

Transfers and Servicing of Financial Assets
    
Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Loans held for sale are generally sold with servicing rights released, however if rights are retained, servicing assets are recognized as separate assets. Servicing rights are originally recorded at fair value within other assets, but subsequently are amortized in proportion to and over the period of estimated net servicing income, and are assessed for impairment at each reporting date. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, default rates and losses. Impairment is determined by stratifying the rights based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the capitalized amount. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the allowance may be recorded as an increase to income.

Servicing fee income is recorded for fees earned for servicing loans for investors. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan, and are recorded as income when earned. The amortization of mortgage servicing rights is recorded as a reduction of loan servicing fee income.

The Company is also a party to certain instruments with off-balance-sheet risk including certain residential loans sold to investors with recourse. The Company’s policy is to record such instruments when funded.

Federal Home Loan Bank Stock

The Company, as a member of the Federal Home Loan Bank (“FHLB”) of Boston, is required to maintain an investment in capital stock of the FHLB. Based on redemption provisions, the stock has no quoted market value and is carried at cost. The Company continually reviews its investment to determine if impairment exists.

Bank Premises and Equipment

Land is carried at cost. Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line convention method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the lease terms or the estimated useful lives of the improvements. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured, not to exceed fifteen years.

Leases

The Company leases office space, space for ATM and parking locations, and certain branch locations under noncancellable operating leases, several of which have renewal options to extend lease terms. Upon commencement of a new lease, the Company will recognize a right of use (“ROU”) asset and corresponding lease liability. The Company makes the decision on whether to renew an option to extend a lease by considering various factors. The Company will recognize an adjustment to its ROU asset and lease liability when lease agreements are amended and executed, or in an event where the Company is reasonably certain that a renewal option will be exercised. The discount rate used in determining the present value of lease payments is based on the Company’s incremental borrowing rate for borrowings with terms similar to each lease at commencement date. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases and non-lease components, such as common area maintenance charges, real estate taxes, and insurance, are not included in the measurement of the lease liability since they are generally able to be segregated. The Company has elected the short-term lease recognition exemption for all leases that qualify. The Company may also assume lease obligations in connection with its acquisition activities, which may result in a market-based favorable or unfavorable lease position, resulting in an intangible lease asset. These intangible lease assets are amortized over the estimated remaining lease term.

The Company is a party to certain equipment lease transactions where it has assumed the role of lessor for purchased assets. These lease transactions are classified by the Company as either operating leases or direct financing leases for accounting purposes, depending upon the nature of the underlying lease agreements. Under operating lease arrangements, the leased asset value is recorded within fixed assets and the Company recognizes rental income over the life of the lease. Under direct financing lease arrangements, the leased asset value is de-recognized and offset with the recognition of a lease receivable that is evaluated for impairment in a manner similar to loans.
Goodwill and Other Intangible Assets

Goodwill represents the excess of the purchase price over the net fair value of acquired businesses. Goodwill is not amortized and is assigned to one reporting unit. Goodwill is evaluated for impairment at least annually, or more often if warranted. In assessing for impairment, the Company has the option to first 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 and circumstances, the Company determines it is more-likely-than-not that the fair value is less than carrying value, a quantitative impairment test is performed to compare carrying value to the fair value of the reporting unit. The Company also has an unconditional option to bypass the assessment of qualitative factors for any period and proceed directly to the quantitative goodwill impairment test. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

Other intangible assets subject to amortization consist of core deposit intangibles, customer lists, and non-compete agreements that are amortized over the estimated lives of the intangibles using a method that approximates the amount of economic benefits that are realized by the Company. Other intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.

Impairment of Long-Lived Assets Other Than Goodwill

The Company reviews long-lived assets, including premises and equipment, for impairment whenever events or changes in business circumstances indicate that the remaining useful life may warrant revision or that the carrying amount of the long-lived asset may not be fully recoverable. The Company performs an undiscounted cash flow analysis to determine if impairment exists. When impairment is determined to exist, the related impairment loss is calculated based on fair value. Impairment losses on assets to be disposed of are based on the estimated proceeds to be received, less costs of disposal.

Cash Surrender Value of Life Insurance Policies

Increases in the cash surrender value (“CSV”) of life insurance policies, as well as benefits received net of any CSV, are recorded in other noninterest income, and are generally not subject to income taxes. The CSV of the policies is recorded as an asset of the Bank, with liabilities recognized for any split dollar arrangements associated with the policies. The Company reviews the financial strength of the insurance carriers prior to the purchase of life insurance policies and no less than annually thereafter. Regulatory requirements limit the total amount of CSV to be held with any individual carrier to 15% of Tier 1 capital (as defined for regulatory purposes) and the total CSV of all life insurance policies is limited to 25% of Tier 1 capital.

Other Real Estate Owned and Other Foreclosed Assets

Real estate properties and other assets, which have served as collateral to secure loans, are held for sale and are initially recorded at fair value less estimated costs to sell at the date control is established, resulting in a new cost basis. The amount by which the recorded investment in the loan exceeds the fair value (net of estimated costs to sell) of the foreclosed asset is charged to the allowance for credit losses. Subsequent declines in the fair value of the foreclosed asset below the new cost basis are recorded through the use of a valuation allowance. Subsequent increases in the fair value are recorded as reductions in the valuation allowance, but not below zero. Upon a sale of a foreclosed asset, any excess of the carrying value over the sale proceeds is recognized as a loss on sale. Any excess of sale proceeds over the carrying value of the foreclosed asset is first applied as a recovery to the valuation allowance, if any, with the remainder being recognized as a gain on sale. Operating expenses and changes in the valuation allowance relating to foreclosed assets are recorded in other noninterest expense.

Derivatives

Derivative instruments are carried at fair value in the Company’s financial statements. The accounting for changes in the fair value of a derivative instrument is determined by whether it has been designated and qualifies as part of a hedging relationship, and further, by the type of hedging relationship. At the inception of a hedge, the Company documents certain items, including but not limited to the following: the relationship between hedging instruments and hedged items, the Company’s risk management objectives, hedging strategies, and the evaluation of hedge transaction effectiveness. Documentation includes linking all derivatives designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific forecasted transactions.
For those derivative instruments that are designated and qualify for special hedge accounting, the Company designates the hedging instrument, based upon the exposure being hedged, as either a fair value hedge or a cash flow hedge. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income, net of related tax. The Company considers any economic mismatch between the hedging instrument and the hedged transaction in its ongoing assessment of hedge effectiveness. If the hedging instrument is not highly effective at achieving offsetting cash flows attributable to the revised contractually specified interest rate(s), hedge accounting will be discontinued. At that time, accumulated other comprehensive income would be frozen and amortized, as long as the forecasted transactions are still probable of occurring. For derivative instruments designated and qualifying as a fair value hedge (i.e., hedging the exposure to changes in the fair value of an asset or liability or an identified portion thereof that is attributable to the hedged risk), the gain or loss on the derivative instrument, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk, are recognized in current earnings during the period of the change in fair values. Hedge accounting is discontinued prospectively when (1) a derivative is no longer highly effective in offsetting changes in the fair value or cash flow of a hedged item, (2) a derivative expires or is settled, (3) it is no longer likely that a forecasted transaction associated with the hedge will occur, or (4) it is determined that designation of a derivative as a hedge is no longer appropriate.

To the extent the Company enters into new or re-designates existing hedging relationships, it is the Company’s policy to include the Overnight Index Swap Rate based on the Fed Funds Effective Rate and the Overnight Index Swap Rate based on the Secured Overnight Financing Rate (“SOFR”) in the spectrum of available benchmark interest rates for hedge accounting.

For derivative instruments not designated as hedging instruments, such as loan level derivatives, foreign exchange contracts, risk participation agreements and mortgage derivatives, changes in fair value are recognized in other noninterest income during the period of change and are included in changes in other assets or other liabilities on the Company’s Consolidated Statement of Cash Flows.

Retirement Plans

The Company has various retirement plans in place for current and former employees, including postretirement benefit plans, supplemental executive retirement plans, a frozen multiemployer pension plan, a frozen defined benefit pension plan, deferred compensation plans, as well as other benefits.

The postretirement benefit plans and the supplemental executive retirement plans are unfunded and therefore have no plan assets. The actuarial cost method used to compute the benefit liabilities and related expense is the projected unit credit method. The projected benefit obligation is principally determined based on the present value of the projected benefit distributions at an assumed discount rate. The discount rate which is utilized is based on the investment yield of high quality corporate bonds available in the market place with maturities approximately equal to projected cash flows of future benefit payments as of the measurement date. Periodic benefit expense (or income) includes service costs and interest costs based on the assumed discount rate, amortization of prior service costs due to plan amendments and amortization of actuarial gains and losses. Service costs are included in salaries and employee benefits and all other costs are included in other noninterest expense. The amortization of actuarial gains and losses is determined using the 10% corridor minimum amortization approach and is taken over the average remaining future working lifetime of the plan participants. The underfunded status of the plans is recorded as a liability on the balance sheet.

The multiemployer pension plan’s assets are determined based on fair value, generally representing observable market prices. The actuarial cost method used to compute the pension liabilities and related expense is the unit credit method. The pension expense is equal to the plan contribution requirement of the Company for the plan year.

The Company maintains two frozen single employer pension plans. The Company accounts for these pension plans using an actuarial model that allocates pension costs over the service period of employees in the plan. The Company accounts for the over-funded or under-funded status of the pension plans as an asset or liability on its consolidated balance sheets and recognizes changes in the funded status that are not reflected in net periodic pension cost as other comprehensive income or loss.

The Director Deferred Compensation Plan allows directors to invest their funds into a diversified investment portfolio and the 401(k) Restoration Plan allows employees to invest their funds in both Company stock and other investment alternatives offered by the Plan. All funds under both of these plans are held in a rabbi trust. The plans do not permit diversification after initial election and therefore elections made to defer into Company stock result in both the investment and
obligation recognized within Stockholders’ Equity. Alternatively, investments not in Company stock are included in trading securities, with the correlating obligation classified as a liability.

The Company has obligations with various individuals related to certain post-retirement benefits. The obligations are based on the individual’s service through retirement, with the associated cost recognized over the requisite service period. The accrual methodology results in an accrued amount at the full eligibility date equal to the then present value of all of the future benefits expected to be paid.    

Stock-Based Compensation

The Company recognizes stock-based compensation based on the grant-date fair value of the award, with no adjustment for estimated forfeitures, as forfeitures are recognized when they occur. For restricted stock awards and units, the Company recognizes compensation expense ratably over the vesting period for the fair value of the award, measured at the grant date. For stock option awards, the Company values awards granted using the Black-Scholes option-pricing model. The Company recognizes compensation expense for these awards on a straight-line basis over the requisite service period for the entire award (straight-line attribution method), ensuring that the amount of compensation cost recognized at any date at least equals the portion of the grant-date fair value of the award that is vested at that time. The Company recognizes excess tax benefits on certain stock compensation transactions. The excess tax benefits are recorded through earnings as a discrete item within the Company’s effective tax rate during the period of the transaction.

Income Taxes

Deferred income tax assets and liabilities are determined using the asset and liability (or balance sheet) method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. If current available information raises doubt as to the realization of the deferred tax assets, a valuation allowance is established. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in enacted tax rates is recognized in income in the period that includes the enactment date. Income taxes are allocated to each entity in the consolidated group based on its share of taxable income. Management exercises significant judgment in evaluating the amount and timing of recognition of the resulting tax liabilities and assets, including projections of future taxable income. Additionally, a liability for unrecognized tax benefits is recorded for uncertain tax positions taken by the Company on its tax returns for which there is less than a 50% likelihood of being recognized upon a tax examination.

Low Income Housing Tax Credits

The Company accounts for its investments in qualified affordable housing projects using the proportional amortization method. Under the proportional amortization method the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment benefit as a component of income tax expense (benefit).

Assets Under Administration

Assets held in a fiduciary or agency capacity for customers are not included in the accompanying consolidated balance sheet, as such assets are not assets of the Company. Revenue from administrative and management activities associated with these assets is recorded on an accrual basis.

Extinguishment of Debt

Upon extinguishment of an outstanding debt, the Company records the difference between the exit price and the net carrying amount of the debt as a gain or loss on the extinguishment. The gain or loss is recorded as a component of other noninterest income or other noninterest expense, respectively.

Earnings Per Share

Basic earnings per share is calculated using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated from common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings, distributed and undistributed, are
allocated to participating securities and common shares based on their respective rights to receive dividends. Unvested share-based payment awards that contain nonforfeitable rights to dividends are considered participating securities, not subject to performance based measures (i.e. unvested time-vested restricted stock). Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding (inclusive of participating securities). Diluted earnings per share have been calculated in a manner similar to that of basic earnings per share except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares (such as those resulting from the exercise of stock options or the attainment of performance measures) were issued during the period, computed using the treasury stock method.

Comprehensive Income

Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, unrealized losses related to factors other than credit on debt securities, if applicable, unrealized gains and losses on cash flow hedges, deferred gains on hedge accounting transactions, and changes in the funded status of the Company’s postretirement and supplemental retirement plans.

Fair Value Measurements

In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters.

Excluded from the table above is accrued interest on available for sale securities of $2.9 million and $3.4 million at December 31, 2024 and 2023, respectively, which is included within other assets on the Consolidated Balance Sheets. Additionally, the Company did not record any write-offs of accrued interest income on available for sale securities for the years ended December 31, 2024 and 2023. Furthermore, no securities held by the Company were delinquent on contractual payments nor were any securities placed on non-accrual status at December 31, 2024 and 2023.

When securities are sold, the adjusted cost of the specific security sold is used to compute the gain or loss on the sale. The Company had no sales of securities available for sale for the years ended December 31, 2024 and 2023, and therefore no gains or losses were realized during the periods presented.
The following tables show the gross unrealized losses and fair value of the Company’s available for sale securities in an unrealized loss position as of the dates indicated.

The Company does not intend to sell these investments and has determined, based upon available evidence, that it is more likely than not that the Company will not be required to sell each security before the recovery of its amortized cost basis. In addition, management does not believe that any of the securities are impaired due to reasons of credit quality. As a result, the Company did not recognize a provision for credit losses on these investments for the years ended December 31, 2024 and 2023. The Company made this determination by reviewing various qualitative and quantitative factors regarding each investment category, such as current market conditions, extent and nature of changes in fair value, issuer rating changes and trends, volatility of earnings, and current analysts’ evaluations.

As a result of the Company’s review of these qualitative and quantitative factors, the causes of the impairments listed in the table above by category were as follows at December 31, 2024:
U.S. Government Agency Securities, U.S. Treasury Securities, Agency Mortgage-Backed Securities, Agency Collateralized Mortgage Obligations and Small Business Administration Pooled Securities: These portfolios have contractual terms that generally do not permit the issuer to settle the securities at a price less than the current par value of the investment. The decline in market value of these securities is attributable to changes in interest rates and not credit quality. Additionally, these securities are implicitly guaranteed by the U.S. Government or one of its agencies.
State, County and Municipal Securities: This portfolio has contractual terms that generally do not permit the issuer to settle the securities at a price less than the current par value of the investment. The decline in market value of these securities is attributable to changes in interest rates and not credit quality.
Pooled Trust Preferred Securities: This portfolio consists of one security which is performing. The unrealized loss on this security is attributable to the illiquid nature of the trust preferred market in the current economic and regulatory environment. Management evaluates collateral credit and instrument structure, including current and expected deferral and default rates and timing. In addition, discount rates are determined by evaluating comparable spreads observed currently in the market for similar instruments.

Substantially all held to maturity securities held by the Company are guaranteed by the U.S. federal government or other government sponsored agencies and have a long history of no credit losses. As a result, management has determined these securities to have a zero loss expectation and therefore the Company did not record a provision for estimated credit losses on any held to maturity securities for the years ended December 31, 2024 and 2023. Excluded from the table above is accrued interest on held to maturity securities of $3.8 million and $4.3 million at December 31, 2024 and 2023, respectively, which is included within other assets on the Consolidated Balance Sheets. Additionally, the Company did not record any write-offs of accrued interest income on held to maturity securities for the years ended December 31, 2024 and 2023. Furthermore, no securities held by the Company were delinquent on contractual payments nor were any securities placed on non-accrual status at December 31, 2024 and 2023.

When securities are sold, the adjusted cost of the specific security sold is used to compute the gain or loss on the sale. The Company had no sales of held to maturity securities for the years ended December 31, 2024 and 2023, and therefore no gains or losses were realized during the periods presented.

The Company monitors the credit quality of held to maturity securities through the use of credit ratings. Credit ratings are monitored by the Company on at least a quarterly basis. At December 31, 2024 and 2023, all held to maturity securities held by the Company were rated investment grade or higher.
The actual maturities of certain available for sale or held to maturity securities may differ from the contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. A schedule of the contractual maturities of securities available for sale and securities held to maturity at December 31, 2024 is presented below:

Share-Based Payment Arrangement [Abstract]  
STOCK BASED COMPENSATION STOCK BASED COMPENSATION   
The Company’s stock based plans include the 2018 Non-Employee Director Stock Plan (the “2018 Plan”) and the 2023 Omnibus Incentive Plan (the “2023 Plan”), which have been approved by the Company’s Board of Directors and shareholders. Shares from the 2018 Plan may be awarded in the form of stock options or restricted stock, and shares from the 2023 Plan may be awarded in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, or other stock-based awards from its pool of authorized but unissued shares. Upon adoption of the 2023 Plan on May 18, 2023, the Second Amended and Restated 2005 Employee Stock Plan (the “2005 Plan”) was terminated in its entirety and the Company no longer grants awards under the 2005 Plan. However, awards outstanding under the 2005 Plan will continue to remain outstanding in accordance with their terms.

The following table presents the amount of cumulatively granted stock option awards and restricted stock awards, net of forfeitures and expirations, granted through December 31, 2024:

The Company has standard form agreements used for stock option and restricted stock awards. The standard form agreements used for the Chief Executive Officer and all other Executive Officers have previously been disclosed in Securities and Exchange Commission filings and generally provide that: (1) any unvested options or unvested restricted stock vest upon a Change of Control; and, that (2) any stock options which vest pursuant to a Change of Control, which is an event described in Section 280G of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), will be cashed out at the difference between the acquisition price and the exercise price of the stock option.
Stock Options

The fair value of each stock option grant is estimated on the date of the grant using the Black-Scholes option-pricing model with the following assumptions used for grants under the identified plans:
Expected volatility is based on the standard deviation of the historical volatility of the weekly adjusted closing price of the Company’s shares for a period equivalent to the expected life of the option.
Expected life represents the period of time that the option is expected to be outstanding, taking into account the contractual term, historical exercise/forfeiture behavior, and the vesting period, if any.
Expected dividend yield is an annualized rate calculated using the most recent dividend payment at time of grant and the Company’s average trailing twelve-month daily closing stock price.
The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equivalent to the expected life of the option.
Forfeitures on stock compensation are recognized when they occur.

For the years ended December 31, 2024, 2023 and 2022, there were no awards granted by the Company of nonqualified options to purchase shares of common stock.
 
Under all of the Company’s stock based plans, the option exercise price is based upon the average of the high and low trading value of the stock on the date of grant. Stock option awards granted to date under all plans expire at various dates through 2028.

At December 31, 2024, all outstanding stock option awards are vested and there is no unrecognized compensation expense related to those options.
Restricted Stock

The Company grants both time-vested restricted stock awards as well as performance-based restricted stock awards. The fair value of the restricted stock awards is based upon the average of the high and low prices at which the Company’s common stock traded on the date of grant. The holders of time-vested restricted stock awards participate fully in the rewards of stock ownership of the Company, including voting and dividend rights. The holders of performance-based restricted stock awards do not participate in the rewards of stock ownership of the Company until vested. The holders of all restricted stock awards are not required to pay any consideration to the Company for the awards.

During the years ended December 31, 2024, 2023, and 2022 the Company made the following restricted stock award grants:

Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivatives and Fair Value DERIVATIVES AND HEDGING ACTIVITIES
The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally to manage the Company’s interest rate risk. Additionally, the Company enters into interest rate derivatives, foreign exchange contracts and risk participation agreements to accommodate the business requirements of its customers (“customer related positions”). The Company minimizes the market and liquidity risks of customer related positions by entering into similar offsetting positions with broker-dealers. Derivative instruments are carried at fair value in the Company’s financial statements. The accounting for changes in the fair value of a derivative instrument is dependent upon whether or not it qualifies as a hedge for accounting purposes, and further, by the type of hedging relationship.

The Company does not enter into proprietary trading positions for any derivatives.

The Company is subject to over-the-counter derivative clearing requirements which require certain derivatives to be cleared through central clearing houses. Accordingly, the Company clears certain derivative transactions through the Chicago Mercantile Exchange Clearing House (“CME”). This clearing house requires the Company to post initial and variation margin to mitigate the risk of non-payment, the latter of which is received or paid daily based on the net asset or liability position of the contracts.

Interest Rate Positions

The Company may utilize various interest rate derivatives as hedging instruments against interest rate risk associated with the Company’s borrowings and loan portfolios. An interest rate derivative is an agreement whereby one party agrees to pay a floating rate of interest on a notional principal amount in exchange for receiving a fixed rate of interest on the same notional amount, for a predetermined period of time, from a second party. The amounts relating to the notional principal amount are not actually exchanged.
The following tables reflect information about the Company’s derivative positions at the dates indicated below for interest rate swaps which qualify as cash flow hedges for accounting purposes:

The maximum length of time over which the Company is currently hedging its exposure to the variability in future cash flows for forecasted transactions related to the payment of variable interest on existing financial instruments is 4.2 years.

For derivative instruments that are designated and qualify as cash flow hedging instruments, the effective portion of the gains or losses is reported as a component of other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The Company expects approximately $1.7 million (pre-tax) to be reclassified as an increase to net interest income and $10.3 million (pre-tax) to be reclassified as a decrease to net interest income, from other comprehensive income related to the Company’s cash flow hedges in the twelve months following December 31, 2024.  This reclassification is due to anticipated payments that will be made and/or received on the swaps based upon the forward curve at December 31, 2024.

The Company had no fair value hedges for the years ended December 31, 2024 and 2023.
Customer Related Positions

Loan level derivatives, primarily interest rate swaps, offered to commercial borrowers through the Company’s loan level derivative program do not qualify as hedges for accounting purposes. The Company believes that its exposure to commercial customer derivatives is limited because these contracts are simultaneously matched at inception with an offsetting dealer transaction. Derivatives with dealer counterparties are then either cleared through a clearinghouse or settled directly with a single counterparty. The commercial customer derivative program allows the Company to retain variable-rate commercial loans while allowing the customer to synthetically fix the loan rate by entering into a variable-to-fixed interest rate swap. The amounts relating to the notional principal amount are not actually exchanged.

Foreign exchange contracts offered to commercial borrowers through the Company’s derivative program do not qualify as hedges for accounting purposes. The Company acts as a seller and buyer of foreign exchange contracts to accommodate its customers. To mitigate the market and liquidity risk associated with these derivatives, the Company enters into similar offsetting positions. The amounts relating to the notional principal amount are exchanged.

The Company has entered into risk participation agreements with other dealer banks in commercial loan agreements. 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 Company participates out a portion of the credit risk associated with the interest rate swap position executed with the commercial borrower for a fee paid to the participating bank. Under a risk participation-in agreement, a derivative liability, the Company assumes, or participates in, a portion of the credit risk associated with the interest rate swap position with the commercial borrower for a fee received from the other bank.

Mortgage Derivatives
    
The Company enters into commitments to fund residential mortgage loans at specified rates and times in the future, with the intention that loans may be sold subsequently in the secondary market. Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. These commitments are recognized at fair value on the Consolidated Balance Sheet in other assets and other liabilities with changes in their fair values recorded within mortgage banking income. In addition, the Company has elected the fair value option to carry loans held for sale at fair value. The change in fair value of loans held for sale is recorded in current period earnings as a component of mortgage banking income in accordance with the Company’s fair value election. The fair value of loans held for sale decreased by $20,000, increased by $97,000 and decreased by $452,000 for the years ended December 31, 2024, 2023 and 2022, respectively. These amounts were offset in earnings by the change in the fair value of mortgage derivatives.
Outstanding loan commitments expose the Company to the risk that the price of the loans arising from exercise of the loan commitment might change from inception of the rate lock to funding of the loan due to changes in mortgage interest rates. If interest rates increase, the value of these loan commitments decreases. Conversely, if interest rates decrease, the value of these loan commitments increases. To protect against the price risk inherent in derivative loan commitments, the Company utilizes both “mandatory delivery” and “best efforts” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Mandatory delivery contracts are accounted for as derivative instruments. Included in the mandatory delivery forward commitments are To Be Announced securities (“TBAs”). Certain assumptions, including pull through rates and rate lock periods, are used in managing the existing and future hedges. The accuracy of underlying assumptions will impact the ultimate effectiveness of any hedging strategies.
    
With mandatory delivery contracts, the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. If the Company fails to deliver the amount of mortgages necessary to fulfill the commitment by the specified date, it is obligated to pay a “pair-off” fee, based on then-current market prices, to the investor/counterparty to compensate the investor for the shortfall. Generally, the Company makes this type of commitment once mortgage loans have been funded and are held for sale, in order to minimize the risk of failure to deliver the requisite volume of loans to the investor and paying pair-off fees as a result. The Company also sells TBA securities to offset potential changes in the fair value of derivative loan commitments. Generally, the Company sells TBA securities by entering into derivative loan commitments for settlement in 30 to 90 days. The Company expects that mandatory delivery contracts, including TBA securities, will experience changes in fair value opposite to the changes in the fair value of derivative loan commitments.
    
With best effort contracts, the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. Generally, best efforts cash contracts have no pair off risk regardless of market movement. The price the investor will pay the seller for an individual loan is specified prior to the loan being funded (e.g., on the same day the lender commits to lend funds to a potential borrower). The Company expects that these best efforts forward loan sale commitments will experience a net neutral shift in fair value with related derivative loan commitments.
    
The aggregate amount of net realized gains on sales of mortgage loans included within mortgage banking income was $4.1 million, $1.0 million and $562,000 for the years ended December 31, 2024, 2023 and 2022, respectively.

Balance Sheet Offsetting

The Company does not offset fair value amounts recognized for derivative instruments. The Company does net the amount recognized for the right to reclaim cash collateral against the obligation to return cash collateral arising from derivative instruments executed with the same counterparty under a master netting arrangement. Collateral legally required to be maintained at dealer banks by the Company is monitored and adjusted as necessary.

A daily settlement occurs through the CME for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through the daily clearing agent. As a result, the total fair values of loan level derivative assets and liabilities recognized on the Company’s financial statements are not equal and offsetting.

The Company’s derivative agreements with institutional counterparties contain various credit-risk related contingent provisions, such as requiring the Company to maintain a well-capitalized capital position. If the Company fails to meet these conditions, the counterparties could request the Company make immediate payment or demand that the Company provide immediate and ongoing full collateralization on derivative positions in net liability positions. All derivative instruments with credit-risk related contingent features were in a net asset position at December 31, 2024 and December 31, 2023.
By using derivatives, the Company is exposed to credit risk to the extent that counterparties to the derivative contracts do not perform as required. Should a counterparty fail to perform under the terms of a derivative contract, the Company’s credit exposure on interest rate swaps is limited to the net positive fair value and accrued interest of all swaps with each counterparty. The Company seeks to minimize counterparty credit risk through credit approvals, limits, monitoring procedures, and obtaining collateral, where appropriate. Institutional counterparties must have an investment grade credit rating and be approved by the Company’s Board of Directors. In addition, certain derivative contracts executed bilaterally with a dealer counterparty in the over-the-counter market are cleared through a clearinghouse, whereby the clearinghouse becomes the counterparty to the transaction. As such, management believes the risk of incurring credit losses on derivative contracts with those counterparties is remote. The Company’s exposure relating to institutional counterparties was $97.0 million and $95.8 million at December 31, 2024 and 2023, respectively. The Company’s exposure relating to customer counterparties was approximately $1.4 million and $5.6 million at December 31, 2024 and 2023, respectively. Credit exposure may be reduced by the value of collateral pledged by the counterparty.

The realization of the tax benefit depends upon the existence of sufficient taxable income in future periods.
Uncertainty in Income Taxes

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction as well as in various states.  The Company is subject to U.S. federal, state and local income tax examinations by tax authorities for the 2021 through 2023 tax years including any related income tax filings from its recent acquisitions.  The Company believes that its income tax returns have been filed based upon applicable statutes, regulations and case law in effect at the time of filing, however, the Internal Revenue Service (“IRS”) and /or state jurisdictions could disagree with the Company’s interpretation upon examination. The Company accounts for uncertainties in income taxes by providing a tax reserve for certain positions. The following is a reconciliation of the beginning and ending amount of unrecognized tax benefits:

Increases to the Company’s unrealized tax positions occur as a result of accruing for any unrecognized tax benefit, as well as the accrual of interest and penalties related to prior year positions. Decreases in the Company’s unrealized tax positions occur as a result of the statute of limitation lapsing on prior year positions and/or settlements relating to outstanding positions. Additionally, the balances noted in the table above do not include the indirect federal benefit of state tax positions of approximately $160,000, $343,000, and $544,000 at December 31, 2024, 2023, and 2022, respectively.

EMPLOYEE BENEFIT PLANS EMPLOYEE BENEFIT PLANS
Pension Plans

The Company maintains a multiemployer defined benefit pension plan (the “Pension Plan”) administered by Pentegra Retirement Services (the “Fund” or “Pentegra Defined Benefit Plan for Financial Institutions”). The Fund does not segregate the assets or liabilities of all participating employers and accordingly, disclosure of plan assets, accumulated vested and nonvested benefits is not possible. Effective July 1, 2006, the Company froze the defined benefit plan by eliminating all future benefit accruals.

In conjunction with the acquisition of Peoples Federal Bancshares, Inc., the parent of Peoples Federal Savings Bank (“Peoples”) in 2015, the Company acquired the Peoples Federal Defined Benefit Pension Plan (“Peoples Plan”). The Peoples Plan was frozen at the date of acquisition and maintained in the same manner as the Pension Plan. The Peoples Plan was also administered by Pentegra Retirement Services under the same Fund as the Pension Plan. Effective July 1, 2024, the Company withdrew The Peoples Bank from the Pension Plan and adopted The Peoples Bank Defined Benefit Pension Plan (“the Peoples DBP Plan”) as a qualified successor plan, which was fully funded. Subsequent to year end, the Company’s Board of Directors voted to terminate the Peoples DBP Plan. Pursuant to the Peoples DBP Plan’s pending termination, all obligations due under the terms of the Peoples DBP Plan will be satisfied during the year ending December 31, 2025.

The Company’s participation in the Pension Plan and the Peoples Plan (the “Pension Plans”) for the annual period ended December 31, 2024, is outlined in the table below. The “EIN/Pension Plan Number” column provides the Employer Identification Number (“EIN”) and the three-digit plan number. The funding status of the Pension Plans is determined on the basis of the financial statements provided by the Fund using total plan assets and accumulated benefit obligation. The “FIP/RP Status Pending/Implemented” column indicates plans for which a financial improvement plan (“FIP”) or a rehabilitation plan (“RP”) is either pending or has been implemented. The “Expiration Date of Collective-Bargaining Agreement” column lists the expiration dates of any collective-bargaining agreement(s) to which the Pension Plans are subject. Financial information for the Fund is made available through the public Form 5500 which is available by April 15th of the year following the plan year end.

Contributions to the Fund are based on each individual employer’s experience. The Company bears the market risk relating to the Pension Plan and will continue to fund the Pension Plan as required. The Pension Plan year is July 1 through June 30. The Company’s total contributions to the Pension Plan did not represent more than 5% of the total contributions to the Pension Plan as indicated in the Pension Plan’s most recently available annual report dated June 30, 2024. The comparability of employer contributions is impacted by asset performance, discount rates and the reduction in the number of covered employees year over year.

The Company’s contributions to the Pension Plans were as follows for the periods indicated:

In conjunction with the acquisition of Blue Hills Bancorp, Inc., parent of Blue Hills Bank (collectively, “BHB”) in 2019, the Company acquired the Savings Banks Employees Retirement Association Pension Plan as adopted by BHB (the “BHB Plan”).  The BHB Plan is administered by Savings Banks Employees Retirement Association and was frozen on October 31, 2014.  Accumulated benefits for participants earned through the end of October 2014 remain secured by the BHB Plan assets as of December 31, 2024 and 2023. Information pertaining to the BHB Plan is as follows:

Assumptions with respect to the expected long-term rate of return are based on prevailing yields on high-quality, fixed-income investments increased by a premium for equity return expectations. In 2022, the Company’s Board of Directors voted to terminate the BHB Plan. As a result, the assets of the BHB plan were transferred to a money market account until the termination is approved by all regulatory bodies, which resulted in a lower long term rate of return on plan assets.

Presented in the table below are the estimated future benefit payments for the BHB Plan. These payments reflect calculated amounts prior to the approval of the BHB Plan's termination.

The Company’s total defined benefit plan expense was $716,000, $487,000, and $562,000, for the years ending December 31, 2024, 2023, and 2022, respectively. The 2024 increase in expense was attributable to the newly adopted Peoples DBP Plan, as described above.

Supplemental Executive Retirement Plans

The Bank maintains frozen defined benefit supplemental executive retirement plans (“SERP”) for certain highly compensated employees designed to offset the impact of regulatory limits on benefits under qualified pension plans. The Bank also maintains defined benefit SERPs acquired from previous acquisitions. The Bank has established and funded rabbi trusts to accumulate funds in order to satisfy the contractual liability of these supplemental retirement plan benefits. These agreements provide for the Bank to pay all benefits from its general assets, and the establishment of these trust funds does not reduce nor otherwise affect the Bank’s continuing liability to pay benefits from such assets except that the Bank’s liability shall be offset by actual benefit payments made from the trusts. The related trust assets included in the Company’s equity securities portfolio totaled $18.7 million and $20.0 million at December 31, 2024 and 2023, respectively.
The following table shows the defined benefit supplemental retirement expense, and the contributions paid to the plans which were used only to pay the current year benefits for the years indicated:

Other Employee Benefits

The Bank may choose to create an incentive compensation plan for senior management and other officers to participate in at varying levels. In addition, the Bank may also pay a discretionary bonus to senior management, officers, and/or non-officers of the Bank. The expense for these incentive plans amounted to $21.3 million, $18.6 million and $24.3 million in 2024, 2023 and 2022, respectively.

The Bank has an Employee Savings Plan that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the Employee Savings Plan, participating employees may defer a portion of their earnings, not to exceed the IRS annual contribution limits. The Bank matches 25% of each employee’s contributions up to the first 6% of the
employee’s eligible earnings. The 401(k) Plan incorporates an Employee Stock Ownership Plan for contributions invested in the Company’s common stock. The Company also provides three defined contributions under this Plan, providing the employees are deemed eligible. To be eligible for these contributions, an employee must complete one year and 1,000 hours of service. The defined contributions are made up of a safe harbor contribution, in which eligible employees receive a 3% cash contribution of eligible earnings to the social security limit, a discretionary contribution in which eligible employees receive a 2% cash contribution of eligible earnings up to the social security limit and a 5% cash contribution of eligible earnings over the social security limit up to the maximum amount permitted by law. Benefits contributed to employees under this defined contribution plan vest immediately. The defined contribution plan expense was $9.6 million, $9.3 million and $8.7 million for the years ended December 2024, 2023 and 2022, respectively.

The Company has a non-qualified deferred compensation plan which allows for deferrals of base salary and incentive payments until an elected distribution date in the future. This deferred compensation plan is available to certain highly compensated employees. Deferrals are invested at the election of the participant into one of the actively managed funds made available to the participant through the Company’s Investment Management Group. The funds are held in a rabbi trust until the elected date of distribution.

The Company has a non-qualified 401(k) Restoration Plan (“Restoration Plan”) for certain executive officers. The Restoration Plan is intended to contribute to each participant the amount of matching and discretionary contributions which would have been made to the existing Rockland Trust 401(k) plan on the participant’s behalf, but were prohibited due to Internal Revenue Code limitations. Deferrals are invested at the election of the participant into one of the actively managed funds made available to the participant through the Company’s Investment Management Group or in the Company’s stock. These funds are held in a rabbi trust until the elected date of distribution. The Company recognized expense of $659,000, $524,000 and $505,000 related to this plan for services performed for the years ended December 31, 2024, 2023 and 2022, respectively.

Also, as part of the Peoples acquisition in 2015, the Company assumed various Salary Continuation Agreements with certain current and former senior executives. The agreements require the payment of specified benefits upon retirement over periods of ten or twenty years as described in each agreement. Expense related to the Salary Continuation Agreements was $221,000, $217,000 and $213,000 for the years ended December 31, 2024, 2023 and 2022, respectively.

Director Benefits    
The Company maintains two deferred compensation plans for the Company’s Board of Directors which permit non-employee directors to defer cash fees, one of which was in effect through December 31, 2018 and a new plan which was adopted effective January 1, 2019. Under the plan in effect through December 31, 2018, deferred compensation was invested in Company stock and held by the Company’s Investment Management Group. Under the plan that took effect January 1, 2019, participating directors may defer all or a portion of their cash compensation into a choice of diversified investment portfolios comprised of stocks, bonds and cash. There was no compensation deferred during 2024 and 2023. Compensation of $113,000 was deferred during 2022.

FAIR VALUE MEASUREMENTS
12 Months Ended
Dec. 31, 2024
Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTS
Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the assumptions applied by the Company when determining fair value reflect those that the Company determines market participants would use to price the asset or liability at the measurement date. If there has been a significant decrease in the volume and level of activity for the asset or liability, regardless of the valuation technique(s) used, the objective of a fair value measurement remains the same. Fair value is the price that would be received if the asset were to be sold or that would be paid if the liability were to be transferred in an orderly market transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. When determining fair value, the Company considers pricing information and other inputs that are current as of the measurement date. In periods of market dislocation, the observability of prices and other inputs may be reduced for certain instruments, or not available at all. The unavailability or reduced availability of pricing or other input information could cause an instrument to be reclassified from one level to another.

The Fair Value Measurements and Disclosures Topic of the FASB ASC defines fair value and establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to
unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under the Fair Value Measurements and Disclosures Topic of the FASB ASC are described below:
Level 1 – Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 2 – Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.
Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Valuation Techniques

There were no changes in the valuation techniques used during the year ended December 31, 2024.

Securities

Trading and Equity Securities

These equity securities are valued based on market quoted prices. These securities are categorized in Level 1 as they are actively traded and no valuation adjustments have been applied.

U.S. Government Agency and U.S. Treasury Securities

Fair value is estimated using either multi-dimensional spread tables or benchmarks. The inputs used include benchmark yields, reported trades, and broker/dealer quotes. These securities are classified as Level 2.

Agency Mortgage-Backed Securities

Fair value is estimated using either a matrix or benchmarks. The inputs used include benchmark yields, reported trades, broker/dealer quotes, and issuer spreads. These securities are categorized as Level 2.

Agency Collateralized Mortgage Obligations and Small Business Administration Pooled Securities

The valuation model for these securities is volatility-driven and ratings based, and uses multi-dimensional spread tables. The inputs used include benchmark yields, reported trades, new issue data, broker dealer quotes, and collateral performance. If there is at least one significant model assumption or input that is not observable, these securities are categorized as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

State, County, and Municipal Securities

The fair value is estimated using a valuation matrix with inputs including bond interest rate tables, recent transaction, and yield relationships. These securities are categorized as Level 2.

Single and Pooled Issuer Trust Preferred Securities

The fair value of trust preferred securities, including pooled and single issuer preferred securities, is estimated using external pricing models, discounted cash flow methodologies or similar techniques. The inputs used in these valuations include benchmark yields, reported trades, new issue data, broker dealer quotes, and collateral performance. If there is at least one significant model assumption or input that is not observable, these securities are classified as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.
Loans Held for Sale

The Company has elected the fair value option to account for originated closed loans intended for sale. The fair value is measured on an individual loan basis using quoted market prices and when not available, comparable market value or discounted cash flow analysis may be utilized. These assets are typically classified as Level 2.

Derivative Instruments

Derivatives

The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings. Additionally, in conjunction with fair value measurement guidance, the Company has made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Although the Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its interest rate derivatives and risk participation agreements may also utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. However, as of December 31, 2024 and 2023, the Company 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 of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are properly classified as Level 2.

Mortgage Derivatives

The fair value of mortgage derivatives is determined based on current market prices for similar assets in the secondary market and, therefore, classified as Level 2 within the fair value hierarchy.

Individually Assessed Collateral Dependent Loans

In accordance with the CECL standard, expected credit losses on individually assessed loans deemed to be collateral dependent are valued based upon the lower of amortized cost or fair value of the underlying collateral less costs to sell.  The inputs used in the appraisals of the collateral are not always observable, and in such cases the loans may be classified as Level 3 within the fair value hierarchy; otherwise, they are classified as Level 2.

Other Real Estate Owned and Other Foreclosed Assets

Other Real Estate Owned (“OREO”) and Other Foreclosed Assets, when applicable, are valued at the lower of cost or fair value of the property, less estimated costs to sell. The fair values are generally estimated based upon recent appraisal values of the property less costs to sell the property. Certain inputs used in appraisals are not always observable, and therefore OREO and Other Foreclosed Assets may be classified as Level 3 within the fair value hierarchy.

Goodwill and Other Intangible Assets

Goodwill and identified intangible assets are subject to impairment testing. The Company conducts an annual impairment test of goodwill in the third quarter of each year, or more frequently if necessary. Other intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. To estimate the fair value of goodwill and, if necessary, other intangible assets, the Company utilizes both a comparable analysis of relevant price multiples in recent market transactions and a discounted cash flow analysis. Both valuation models require a significant degree of management judgment. In the event the fair value as determined by the valuation model is less than the carrying value, the intangibles may be impaired. If the impairment testing resulted in impairment, the Company would classify the impaired goodwill and other intangible assets subjected to nonrecurring fair value adjustments as Level 3.

(b)Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.
(c)Federal Home Loan Bank stock has no quoted market value and is carried at cost, therefore the carrying amount approximates fair value.
(d)Cash surrender value of life insurance is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.
(e)Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.
(f)Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.
(g)Fair value was determined based upon market prices of securities with similar terms and maturities.

This summary excludes certain financial assets and liabilities for which the carrying value approximates fair value. For financial assets, these may include cash and due from banks, federal funds sold and short-term investments. For financial liabilities, these may include federal funds purchased. These instruments would all be considered to be classified as Level 1 within the fair value hierarchy. Also excluded from the summary are financial instruments measured at fair value on a recurring and nonrecurring basis, as previously described.

The Company considers its current use of financial instruments to be the highest and best use of the instruments.

REVENUE RECOGNITION (Notes)

Revenue Recognition [Abstract]  
Revenue from Contract with Customer [Text Block] REVENUE RECOGNITION
A portion of the Company’s noninterest income is derived from contracts with customers, and as such, the revenue recognized depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company accounts for such revenues in accordance with ASC 606 - Revenue from Contracts with Customers and considers the terms of the contract and all relevant facts and circumstances when applying this guidance. To ensure its alignment with this core principle, the Company measures revenue and the timing of recognition by applying the following five steps:

1.Identify the contract(s) with customers
2.Identify the performance obligations
3.Determine the transaction price
4.Allocate the transaction price to the performance obligations
5.Recognize revenue when (or as) the entity satisfies a performance obligation
    
The Company has disaggregated its revenue from contracts with customers into categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. The following table presents the revenue streams that the Company has disaggregated for the periods indicated:

Total noninterest income$128,014 $124,609 $114,667 

In each of the revenue streams identified above, there were no significant judgments made in determining or allocating the transaction price, as the consideration and service requirements are generally explicitly identified in the associated contracts. Additional information related to each of the revenue streams is further noted below.

Deposit Account Fees

The Company offers various deposit account products to its customers governed by specific deposit agreements applicable to either personal customers or business customers. These agreements identify the general conditions and obligations of both parties, and include standard information regarding deposit account related fees.

Deposit account services include providing access to deposit accounts as well as access to the various deposit transactional services of the Company. These transactional services are primarily those that are identified in the standard fee schedule, and include, but are not limited to, services such as overdraft protection, wire transfer, and check collection. Revenue is recognized in conjunction with the various services being provided. For example, the Company may assess monthly fixed service fees associated with the customer having access to the deposit account, which can vary depending on the account type and daily account balance. In addition, the Company may also assess separate fixed fees associated with and at the time specific transactions are entered into by the customer. As such, the Company considers its performance obligations to be met concurrently with providing the account access or completing the requested deposit transaction.
Cash Management
        
Cash management services are a subset of the Deposit account fees revenue stream. These services primarily include ACH transaction processing, positive pay and remote deposit services. These services are also governed by separate agreements entered into with the customer. The fee arrangement for these services is structured to assess fees under one of two scenarios, either a per transaction fee arrangement or an earnings credit analysis arrangement. Under the per transaction fee arrangement, fixed fees are assessed concurrently with customers executing the transactions, and as such, the Company considers its performance obligations to be met concurrently with completing the requested transaction. Under the earnings credit analysis arrangement, the Company provides a monthly earnings credit to the customer that is negotiated and determined based on various factors. The credit is then available to absorb the per transaction fees that are assessed on the customer's deposit account activity for the month. Any amount of the transactional fees in excess of the earnings credit is recognized as revenue in that month.

Interchange Fees

The Company earns interchange revenue from its issuance of credit and debit cards granted through its membership in various card payment networks. The Company provides credit cards and debit cards to its customers which are authorized and settled through these payment networks, and in exchange, the Company earns revenue as determined by each payment network's interchange program. The revenue is recognized concurrently with the settlement of card transactions within each network.

ATM Fees

The Company deploys automated teller machines (ATMs) as part of its overall branch network. Certain transactions performed at the ATMs require customers to acknowledge and pay a fee for the requested service. Certain ATM fees are disclosed in the deposit account agreement fee schedules, whereas those assessed to non-Rockland Trust deposit holders are solely determined during the transaction at the machine.

The ATM fee is a fixed dollar per transaction amount, and as such, is recognized concurrently with the overall daily processing and settlement of the ATM activity.

Investment Management - Wealth Management and Advisory Services

The Company offers investment management and trust services to individuals, institutions, small businesses and charitable institutions. Each investment management product is governed by its own contract along with a separate identifiable fee schedule unique to that product. The Company also offers additional services, such as estate settlement, financial planning, tax services and other special services quoted at the client’s request.

Asset management and/or custody fees are based upon a percentage of the monthly valuation of the principal assets in the customer’s account, whereas fees for additional or special services are fixed in nature and are charged as services are rendered. As the fees are dependent on assets under management, which are susceptible to market factors outside of the Company’s control, this variable consideration is constrained and therefore no revenue is estimated at contract initiation. As such, all revenue is recognized in correlation to the monthly management fee determinations or as transactional services are provided. Due to the fact that payments are primarily made subsequent to the valuation period, the Company records a receivable for revenue earned but not received. The following table provides the amount of investment management revenue earned but not received as of the dates indicated:
December 31, 2024December 31, 2023
(Dollars in thousands)
Receivables, included in other assets$5,968 $5,509 

Investment Management - Retail Investments and Insurance Revenue

The Company offers the sale of mutual fund shares, unit investment trust shares, third party model portfolios, general securities, fixed and variable annuities and life insurance products through registered representatives who are both employed by the Company and licensed and contracted with various Broker General Agents to offer these products to the Company’s customer base. As such, the Company performs these services as an agent and earns a fixed commission on the sales of these
products and services. To a lesser degree, production bonus commissions can also be earned based upon the Company meeting certain volume thresholds.

In general, the Company recognizes commission revenue at the point of sale, and for certain insurance products, may also earn and recognize annual residual commissions commensurate with annual premiums being paid.

Payment Processing Income
    
The Company refers customers to third party payment processing partners in exchange for commission and fee income. The income earned is comprised of multiple components, including a fixed referral fee per each referred customer, a rebate amount determined primarily as a percentage of net revenue earned by the third party from services provided to each referred customer, and overall production bonus commissions if certain new account production thresholds are met. Payment processing income is recognized in conjunction with either completing the referral to earn the fixed fee amount or as the merchant activity is processed to derive the Company’s rebate and/or production bonus amounts.
    
Credit Card Income

The Company provides consumer and business credit card solutions to its customers by soliciting new accounts on behalf of a third party credit card provider in exchange for a fee. The income earned is comprised of new account incentive payments as well as a percentage of interchange income earned by the third party provider offering the consumer and business purpose revolving credit accounts. The credit card income is recognized in conjunction with the establishment of each new credit card member or as the interchange is earned by the third party in connection with net purchase transactions made by the credit card member.

Other Noninterest Income

The Company earns various types of other noninterest income that fall within the scope of the new revenue recognition rules, and have been aggregated into one general revenue stream in the table noted above. This amount includes, but is not limited to, the following types of revenue with customers:

Safe Deposit Rent

    The Company rents out the use of safe deposit boxes to its customers, which can be accessed when the bank is open for business. The safe deposit box rental fee is paid upfront and is recognized as revenue ratably over the annual term of the contract.

Foreign Currency

    The Company earns fee income associated with various transactions related to foreign currency product offerings, including foreign currency bank notes and drafts and foreign currency wires. The majority of this income is derived from commissions earned related to customers executing the above mentioned foreign currency transactions through arrangements with third party correspondents.

Leases [Abstract]  
Lessee, Operating Leases [Text Block] LEASES
As of December 31, 2024, the Company had entered into 117 noncancellable operating lease agreements for office space, parking, space for ATM locations and certain branch locations, several of which contain renewal options to extend lease terms for a period of 2 to 20 years. The Company has no material financing leases outstanding and no leases with residual value guarantees.

As of December 31, 2024, the Company did not have any material sub-lease agreements.

The Company’s right-of-use asset related to operating leases totaled $54.5 million and $54.1 million at December 31, 2024 and 2023, respectively, and is recognized in the Company’s Consolidated Balance Sheet within other assets.

When a decision is made to exit a leased location, the Company may incur certain termination costs and/or lease impairment charges, if applicable. Accordingly, the Company recognized $555,000, $589,000, and $4.4 million of such exit costs during the years ended December 31, 2024, 2023, and 2022, respectively, with the 2022 costs recorded through merger and acquisition expense within the Consolidated Income Statements in relation to the Meridian acquisition.

Commitments and Contingencies Disclosure [Abstract]  
COMMITMENTS AND CONTINGENCIES COMMITMENTS AND CONTINGENCIES
Financial Instruments with Off-Balance Sheet Risk

In the normal course of business, the Company enters into various transactions to meet the financing needs of its customers, which, in accordance with GAAP, are not included in its consolidated balance sheets. These transactions include commitments to extend credit, standby letters of credit, and loans sold with recourse, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Company minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.
    
The Company enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of these commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding.
    
Standby letters of credit are written conditional commitments issued to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Company would be entitled to seek recovery from the customer. The Company’s policies generally require that standby letter of credit arrangements contain security and other covenants similar to those contained in loan agreements.
    
The fees collected in connection with the issuance of standby letters of credit are representative of the fair value of the obligation undertaken in issuing the guarantee. In accordance with applicable accounting standards related to guarantees, fees collected in connection with the issuance of standby letters of credit are deferred. The fees are then recognized in income proportionately over the life of the standby letter of credit agreement. The deferred standby letter of credit fees represent the fair value of the Company’s potential obligations under the standby letter of credit guarantees.

REGULATORY CAPITAL REQUIREMENTS

Regulated Operations [Abstract]  
REGULATORY CAPITAL REQUIREMENTS REGULATORY MATTERS
Regulatory Capital Requirements

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and the Bank’s assets, liabilities and certain off-
balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

At December 31, 2024 the Bank’s capital levels met or exceeded the minimum levels to be considered “well capitalized” for bank regulatory purposes. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, Common equity Tier 1 risk-based and Tier 1 leverage ratios as set forth in the following tables. Management believes, as of December 31, 2024 and 2023, that the Company and the Bank met all capital adequacy requirements to which they are subject.

The Company’s and the Bank’s actual capital amounts and ratios as of December 31, 2024 and 2023 are also presented in the table that follows:

In addition to the minimum risk-based capital requirements outlined in the table above, the Company is required to maintain a minimum capital conservation buffer, in the form of common equity, in order to avoid restrictions on capital distributions and discretionary bonuses. The required amount of the capital conservation buffer is 2.5%. The Company’s capital levels exceeded the minimum requirement plus the buffer of 2.5% as of December 31, 2024 and 2023.
Dividend Restrictions

The Company is subject to capital and dividend requirements administered by federal and state bank regulators, and the Company will not declare a cash dividend that would cause the Company to violate regulatory requirements. The Company is, in the ordinary course of business, dependent upon the receipt of cash dividends from the Bank to pay cash dividends to shareholders and satisfy the Company’s other cash needs. Federal and state law impose limits on capital distributions by the Bank. Massachusetts-chartered banks, such as the Bank, may declare from net profits cash dividends not more frequently than quarterly and non-cash dividends at any time. No dividends may be declared, credited, or paid if the Bank’s capital stock would be impaired. Massachusetts Bank Commissioner approval is required if the total of all dividends declared by the Bank in any calendar year would exceed the total of its net profits for that year combined with its retained net profits of the preceding two years, less any required transfer to surplus or a fund for the retirement of any preferred stock. Dividends paid by the Bank to the Company for the years ended December 31, 2024 and 2023 totaled $183.8 million and $228.9 million, respectively.

Trust Preferred Securities
In accordance with the applicable accounting standard related to variable interest entities, the common stock of trusts which have issued trust preferred securities have not been included in the consolidated financial statements of the Company. At both December 31, 2024 and 2023, there were $61.0 million in trust preferred securities that have been included within Tier 2 Capital of the Company for regulatory reporting purposes, pursuant to the Federal Reserve’s capital adequacy guidelines.

Segment Reporting [Abstract]  
Segment Reporting Disclosure SEGMENT INFORMATION
The Company is a bank holding company, the principal subsidiary of which is the Bank. The Bank provides a variety of banking, investment, and financial services through its retail branches, commercial banking centers, investment management offices, and mortgage lending centers throughout Eastern Massachusetts, as well as Worcester County (Massachusetts) and Rhode Island. The Bank is a community-oriented commercial bank, and has only one reportable segment, which is community banking. The community banking segment derives revenues primarily from providing loans to individuals and small-to-medium sized businesses in its market area. The accounting policies of the community banking segment are the same as those described in Note 1, “Summary of Significant Accounting Policies” within the Notes to Consolidated Financial Statements included in Item 8.

The Company’s reportable segment is determined by the Chief Executive Officer and Chief Financial Officer, who are the Company’s designated chief operating decision makers ("CODMs"), based upon information about the Company’s products and services offered to customers as part of its community banking operations. The CODMs assess performance for the community banking segment and decide how to allocate resources based on the Company’s consolidated net income and diluted earnings per share, as reported in the Consolidated Statements of Income. The significant expense categories reviewed by the CODMs are also consistent with those presented on the Consolidated Statements of Income, with an emphasis on interest expense on deposits and borrowings, as well as provision for credit losses, salaries and benefits, and occupancy and equipment costs. Other segment expenses are comprised of the remaining expense categories presented on the Consolidated Statements of income, including other non-interest expenses. Other non-interest expenses are inclusive of costs related to professional services, advertising, technology and communications costs, and various other general and administrative costs. Net income and diluted earnings per share are used by the CODMs to monitor management’s budgeted results versus actual, as well as to benchmark the Company’s relative performance against other banking institutions in its peer group. The results of these monitoring and benchmarking analyses are used in assessing performance of the community banking segment and to inform decisions surrounding general corporate strategy, capital allocations, and compensation. Asset details provided to the CODMs
are consistent with those reported on the Consolidated Balance Sheets, with an emphasis on interest-earning assets, including loans and investment securities, which provide the majority of revenues generated by the community banking segment.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]  
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block] CYBERSECURITY
Cybersecurity threats pose a risk to the Company, as crimes committed through or involving the internet, such as phishing, hacking, denial of service attacks, stealing information, unauthorized intrusions into the Company’s internal systems or the systems of the Company’s third-party vendors could adversely impact the Company’s operations or damage its reputation. The Bank manages cybersecurity threats proactively and maintains robust controls to protect its critical systems and data by investing in secure, reliable, and resilient technology infrastructure, fostering a culture of technology risk awareness, and continuously improving its technology risk management practices. The Company’s process for monitoring and mitigating cybersecurity risk is designed in conjunction with its overall Enterprise Risk Management Policy. The Company’s Information Security Program follows ISO 27002, an international standard for information security controls, as well as references to the Federal Financial Institutions Examination Council Information Examination Handbook, and other regulatory guidance and industry standards.

The Company has several processes in place to oversee and identify these risks, such as the Information Technology Risk Governance Committee (“ITRGC”), which is responsible for oversight of information technology (“IT”) and information security (“IS”) risk. This committee oversees the establishment and revision of IT and IS key risk and key performance indicators and ongoing monitoring of these metrics. The Company’s Chief Information Security Officer (“CISO”) is responsible for cybersecurity initiatives at the Company, including identifying and managing security risks, and escalating elevated risks with the Chief Risk Officer (“CRO”) where applicable. Together, the CISO and the CRO report on emerging and existing threats and mitigation strategies to the Board, which has oversight of cybersecurity risk, on a semi-annual basis, or more frequently, if needed. The CISO has over 30 years of information security experience, with experienced team members that come from a wide range of industries and possess substantial knowledge and expertise in how to manage information security and cybersecurity risks. Additionally, the team of employees supporting the CISO maintain education and certification requirements necessary to fulfill their responsibilities.

The Company has deployed a layered security approach to identify, measure, monitor and control information technology risks. The Company also maintains a documented Incident Management Standard and Technology and Cyber Incident Response Plan. These documents address the detection, mitigation, and remediation of cybersecurity incidents, and include appropriate timely incident escalations to be followed during an incident, up to and including executive leadership, management committees and depending on incident severity, the Board, or a Board committee. The volume, severity, and root case of security incidents are reported on at monthly management committees. The Company will regularly engage independent third parties to assist in its cybersecurity preparedness, including but not limited to vulnerability scan assessments, secure code scan reviews, and cybersecurity incident response simulations. The Company’s internal audit department also performs annual cybersecurity penetration testing over the Company’s internal and external networks. Additionally, for third party related technologies, the Company’s Third-Party Risk Management Program (“TPRM”) is involved with onboarding all vendors, including ongoing monitoring of higher risk vendor relationships. TPRM documents the Company’s view of applicable third-party vendors assessing the vendor’s technological capability to provide products and/or services in a viable and risk adverse manner.

In an effort to mitigate risks related to cybersecurity threats, the Company has also designed and implemented required training for all employees, including training on the Company’s security and privacy policies, which are mandatory as part of the onboarding process, with refresher trainings required annually thereafter. Additionally, the Company conducts regular phishing simulation tests throughout the year to keep employees alert, spread awareness and ensure that employees have the knowledge and resources necessary to report suspicious activity.

While the Company has seen attempts to gain access to its systems, and expects such attacks to continue, or possibly intensify in the future, the Company has not experienced any material losses relating to cyber-attacks or other information security breaches as of December 31, 2024. As a protective measure, the Company maintains insurance coverage for cybersecurity incidents experienced by the Company, or by one or more of the Company’s third-party providers, however such insurance coverage may not be sufficient to cover all losses incurred. As of the date of this Report, no risks from cybersecurity
threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial condition. For further discussion surrounding risks from cybersecurity threats, refer to the section captioned “Risks Related to Information Security and Technology” within Part I. Item 1A of this Report.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]  
PRINCIPLES OF CONSOLIDATION
The consolidated financial statements include the accounts of the Company, the Bank and other wholly-owned subsidiaries, except subsidiaries that are not deemed necessary to be consolidated. All significant intercompany balances and transactions have been eliminated in consolidation.

The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity under GAAP. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. The Company would consolidate voting interest entities in which it has all, or at least a majority of, the voting interest. As defined in applicable accounting standards, variable interest entities (“VIEs”) are entities that lack one or more of the characteristics of a voting interest entity.  A controlling financial interest in a VIE is present when the Company has both the power and ability to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. 

The Company also owns the common stock of various trusts which have issued trust preferred securities. These trusts are VIEs in which the Company is not the primary beneficiary and, therefore, are not consolidated. The trust's only assets are junior subordinated debentures issued by the Company, which were acquired by the trust using the proceeds from the issuance of the trust preferred securities and common stock. The junior subordinated debentures are included in long-term debt and the Company’s equity interest in the trust is included in other assets in the accompanying Consolidated Balance Sheets. Interest expense on the junior subordinated debentures is reported in interest expense on long-term debt in the accompanying Consolidated Statements of Income.
RECLASSIFICATION
Reclassification

Certain previously reported amounts have been reclassified to conform to the current year’s presentation, including the following:

the Company reclassified its portfolio of loans secured by owner-occupied commercial real estate to the commercial and industrial loan category to more appropriately reflect the variation in the management and underlying risk profile of such loans compared with investor-owned commercial real estate loans; and
the Company combined the presentation of “Software maintenance” and “Subscriptions” costs into “Software and subscriptions” costs within Non-interest expense within the Consolidated Statements of Income. Previously, “Subscriptions” costs were included within “Other noninterest expenses.”
USE OF ESTIMATES
Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting periods. Actual results could vary from these estimates. Material estimates that are particularly susceptible to significant changes in the near-term relate to the determination of the allowance for expected credit losses on loans held for investment, income taxes, valuation and allowance for expected credit losses on investment securities, and the valuation of goodwill and other intangible assets and their respective analyses of impairment.
SIGNIFICANT CONCENTRATIONS OF CREDIT RISK
Concentrations of Credit Risk
The vast majority of the Bank’s lending activities are conducted in New England. The Bank originates commercial and industrial loans, commercial and residential real estate loans, including construction loans, small business loans, home equity loans, and other consumer loans for its portfolio. The Bank tracks concentrations of credit across numerous categories and segments based on aggregate credit exposure, which includes direct, indirect or contingent obligations to a borrower or group of borrowers engaged in one industry and by property type. The Bank considers a concentration to exist when aggregate credit exposure of a category or segment exceeds 25% of the Bank's total risk-based capital (inclusive of Tier 2 capital instruments).
CASH AND CASH EQUIVALENTS
Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents may include cash on hand, amounts due from banks, inclusive of interest-earning deposits held at banks, and federal funds sold. Generally, federal funds are sold for up to two week periods.
SECURITIES
Securities

Investment securities are classified at the time of purchase as available for sale, held to maturity, trading, or equity. Classification is constantly re-evaluated for consistency with corporate goals and objectives. Trading and equity securities are recorded at fair value with subsequent changes in fair value recorded in earnings. Debt securities that management has the positive intent and ability to hold to maturity are classified as held to maturity and recorded at amortized cost. Securities not classified as held to maturity or trading are classified as available for sale and recorded at fair value, with changes in fair value excluded from earnings and reported in other comprehensive income, net of related tax. Purchase premiums and discounts are recognized in interest income, using the interest method, to arrive at periodic interest income at a constant effective yield, thereby reflecting the securities market yield. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Such gains and losses are recognized within non-interest income or non-interest expense within the Consolidated Statements of Income.

Accrued interest receivable balances are excluded from the amortized cost of held to maturity securities and the fair value of available for sale securities and are included within other assets on the Consolidated Balance Sheets. Management has elected not to measure an allowance for credit losses on these balances as the Company employs a timely write-off policy. It is the Company’s policy that a security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent, and interest earned but not collected for a security placed on non-accrual is reversed against interest income.

Allowance for Credit Losses - Available for Sale Securities

The Company’s available for sale securities are carried at fair value and assessed for estimated credit losses in accordance with the current expected credit loss (“CECL” methodology). For available for sale securities in an unrealized loss position, management will first evaluate whether there is intent to sell, or if it is more likely than not that the Company will be required to sell a security prior to anticipated recovery of its amortized cost basis. If either of these criteria are met, the Company will record a write-down of the security’s amortized cost basis to fair value through income. For those available for sale securities which do not meet the intent or requirement to sell criteria, management will evaluate whether the decline in fair value is a result of credit related matters or other factors. In performing this assessment, management considers the
creditworthiness of the issuer including whether the security is guaranteed by the U.S. Federal Government or other government agency, the extent to which fair value is less than amortized cost, and changes in credit rating during the period, among other factors. If this assessment indicates the existence of credit losses, the security will be written down to fair value, as determined by a discounted cash flow analysis. To the extent the estimated cash flows do not support the amortized cost, the deficiency is considered to be due to credit loss and is recognized in earnings.

Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit loss expense. Losses are charged against the allowance when the uncollectibility of a security is confirmed, or when either of the aforementioned criteria surrounding intent or requirement to sell have been met.

Allowance for Credit Losses - Held to Maturity Securities

The Company measures expected credit losses on held to maturity securities on a collective basis by major security type in accordance with the CECL methodology. Management classifies the held to maturity portfolio into the following major security types: U.S. Government Agency, U.S. Treasury, Agency Mortgage-Backed Securities, Agency Collateralized Mortgage Obligations, Small Business Administration Pooled Securities, and Single Issuer Trust Preferred Securities. Securities in the Company’s held to maturity portfolio are primarily guaranteed by either the U.S. Federal Government or other government sponsored agencies with a long history of no credit losses. As a result, management has determined these securities to have a zero loss expectation and therefore does not estimate an allowance for credit losses on these securities.
LOANS HELD FOR SALE
Loans Held for Sale

The Bank may choose to classify new residential real estate mortgage loans as held for sale based on intent, which is determined when loans are underwritten. Loans that are classified as held for sale at the time of origination are accounted for under the fair value option, whereby any changes in fair value relating to loans intended for sale are recorded in earnings and are offset by changes in fair value relating to interest rate lock commitments and forward sales commitments. Gains and losses on residential loan sales (sales proceeds minus carrying amount) are recorded in mortgage banking income. Upfront costs and fees related to items for which the fair value option is elected are recognized in earnings as incurred and are not deferred.

Alternatively, any loans not originated for sale but subsequently transferred from held for investment to held for sale are valued at the lower of cost or fair value on an individual asset basis. Prospectively, any cost amounts in excess of fair value would be recorded as a valuation allowance and recognized as a reduction of other non-interest income.
FEDERAL HOME LOAN BANK STOCK
Federal Home Loan Bank Stock
The Company, as a member of the Federal Home Loan Bank (“FHLB”) of Boston, is required to maintain an investment in capital stock of the FHLB. Based on redemption provisions, the stock has no quoted market value and is carried at cost. The Company continually reviews its investment to determine if impairment exists.
BANK PREMISES AND EQUIPMENT
Bank Premises and Equipment

Land is carried at cost. Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line convention method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the lease terms or the estimated useful lives of the improvements. Expected terms include lease option periods to the extent that the exercise of such options is reasonably assured, not to exceed fifteen years.

Leases

The Company leases office space, space for ATM and parking locations, and certain branch locations under noncancellable operating leases, several of which have renewal options to extend lease terms. Upon commencement of a new lease, the Company will recognize a right of use (“ROU”) asset and corresponding lease liability. The Company makes the decision on whether to renew an option to extend a lease by considering various factors. The Company will recognize an adjustment to its ROU asset and lease liability when lease agreements are amended and executed, or in an event where the Company is reasonably certain that a renewal option will be exercised. The discount rate used in determining the present value of lease payments is based on the Company’s incremental borrowing rate for borrowings with terms similar to each lease at commencement date. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases and non-lease components, such as common area maintenance charges, real estate taxes, and insurance, are not included in the measurement of the lease liability since they are generally able to be segregated. The Company has elected the short-term lease recognition exemption for all leases that qualify. The Company may also assume lease obligations in connection with its acquisition activities, which may result in a market-based favorable or unfavorable lease position, resulting in an intangible lease asset. These intangible lease assets are amortized over the estimated remaining lease term.

The Company is a party to certain equipment lease transactions where it has assumed the role of lessor for purchased assets. These lease transactions are classified by the Company as either operating leases or direct financing leases for accounting purposes, depending upon the nature of the underlying lease agreements. Under operating lease arrangements, the leased asset value is recorded within fixed assets and the Company recognizes rental income over the life of the lease. Under direct financing lease arrangements, the leased asset value is de-recognized and offset with the recognition of a lease receivable that is evaluated for impairment in a manner similar to loans.
GOODWILL AND IDENTIABLE INTANGIBLE ASSETS
Goodwill and Other Intangible Assets

Goodwill represents the excess of the purchase price over the net fair value of acquired businesses. Goodwill is not amortized and is assigned to one reporting unit. Goodwill is evaluated for impairment at least annually, or more often if warranted. In assessing for impairment, the Company has the option to first 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 and circumstances, the Company determines it is more-likely-than-not that the fair value is less than carrying value, a quantitative impairment test is performed to compare carrying value to the fair value of the reporting unit. The Company also has an unconditional option to bypass the assessment of qualitative factors for any period and proceed directly to the quantitative goodwill impairment test. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.
Other intangible assets subject to amortization consist of core deposit intangibles, customer lists, and non-compete agreements that are amortized over the estimated lives of the intangibles using a method that approximates the amount of economic benefits that are realized by the Company. Other intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.
IMPAIRMENT OF LONG-LIVED ASSETS OTHER THAN GOODWILL
Impairment of Long-Lived Assets Other Than Goodwill

The Company reviews long-lived assets, including premises and equipment, for impairment whenever events or changes in business circumstances indicate that the remaining useful life may warrant revision or that the carrying amount of the long-lived asset may not be fully recoverable. The Company performs an undiscounted cash flow analysis to determine if impairment exists. When impairment is determined to exist, the related impairment loss is calculated based on fair value. Impairment losses on assets to be disposed of are based on the estimated proceeds to be received, less costs of disposal.
CASH SURRENDER VALUE OF LIFE INSURANCE POLICIES
Cash Surrender Value of Life Insurance Policies

Increases in the cash surrender value (“CSV”) of life insurance policies, as well as benefits received net of any CSV, are recorded in other noninterest income, and are generally not subject to income taxes. The CSV of the policies is recorded as an asset of the Bank, with liabilities recognized for any split dollar arrangements associated with the policies. The Company reviews the financial strength of the insurance carriers prior to the purchase of life insurance policies and no less than annually thereafter. Regulatory requirements limit the total amount of CSV to be held with any individual carrier to 15% of Tier 1 capital (as defined for regulatory purposes) and the total CSV of all life insurance policies is limited to 25% of Tier 1 capital.
OTHER REAL ESTATE OWNED AND OTHER FORECLOSED ASSETS
Other Real Estate Owned and Other Foreclosed Assets

Real estate properties and other assets, which have served as collateral to secure loans, are held for sale and are initially recorded at fair value less estimated costs to sell at the date control is established, resulting in a new cost basis. The amount by which the recorded investment in the loan exceeds the fair value (net of estimated costs to sell) of the foreclosed asset is charged to the allowance for credit losses. Subsequent declines in the fair value of the foreclosed asset below the new cost basis are recorded through the use of a valuation allowance. Subsequent increases in the fair value are recorded as reductions in the valuation allowance, but not below zero. Upon a sale of a foreclosed asset, any excess of the carrying value over the sale proceeds is recognized as a loss on sale. Any excess of sale proceeds over the carrying value of the foreclosed asset is first applied as a recovery to the valuation allowance, if any, with the remainder being recognized as a gain on sale. Operating expenses and changes in the valuation allowance relating to foreclosed assets are recorded in other noninterest expense.
DERIVATIVES
Derivatives

Derivative instruments are carried at fair value in the Company’s financial statements. The accounting for changes in the fair value of a derivative instrument is determined by whether it has been designated and qualifies as part of a hedging relationship, and further, by the type of hedging relationship. At the inception of a hedge, the Company documents certain items, including but not limited to the following: the relationship between hedging instruments and hedged items, the Company’s risk management objectives, hedging strategies, and the evaluation of hedge transaction effectiveness. Documentation includes linking all derivatives designated as fair value or cash flow hedges to specific assets and liabilities on the balance sheet or to specific forecasted transactions.
For those derivative instruments that are designated and qualify for special hedge accounting, the Company designates the hedging instrument, based upon the exposure being hedged, as either a fair value hedge or a cash flow hedge. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income, net of related tax. The Company considers any economic mismatch between the hedging instrument and the hedged transaction in its ongoing assessment of hedge effectiveness. If the hedging instrument is not highly effective at achieving offsetting cash flows attributable to the revised contractually specified interest rate(s), hedge accounting will be discontinued. At that time, accumulated other comprehensive income would be frozen and amortized, as long as the forecasted transactions are still probable of occurring. For derivative instruments designated and qualifying as a fair value hedge (i.e., hedging the exposure to changes in the fair value of an asset or liability or an identified portion thereof that is attributable to the hedged risk), the gain or loss on the derivative instrument, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk, are recognized in current earnings during the period of the change in fair values. Hedge accounting is discontinued prospectively when (1) a derivative is no longer highly effective in offsetting changes in the fair value or cash flow of a hedged item, (2) a derivative expires or is settled, (3) it is no longer likely that a forecasted transaction associated with the hedge will occur, or (4) it is determined that designation of a derivative as a hedge is no longer appropriate.

To the extent the Company enters into new or re-designates existing hedging relationships, it is the Company’s policy to include the Overnight Index Swap Rate based on the Fed Funds Effective Rate and the Overnight Index Swap Rate based on the Secured Overnight Financing Rate (“SOFR”) in the spectrum of available benchmark interest rates for hedge accounting.
For derivative instruments not designated as hedging instruments, such as loan level derivatives, foreign exchange contracts, risk participation agreements and mortgage derivatives, changes in fair value are recognized in other noninterest income during the period of change and are included in changes in other assets or other liabilities on the Company’s Consolidated Statement of Cash Flows.
RETIREMENT PLANS
Retirement Plans

The Company has various retirement plans in place for current and former employees, including postretirement benefit plans, supplemental executive retirement plans, a frozen multiemployer pension plan, a frozen defined benefit pension plan, deferred compensation plans, as well as other benefits.

The postretirement benefit plans and the supplemental executive retirement plans are unfunded and therefore have no plan assets. The actuarial cost method used to compute the benefit liabilities and related expense is the projected unit credit method. The projected benefit obligation is principally determined based on the present value of the projected benefit distributions at an assumed discount rate. The discount rate which is utilized is based on the investment yield of high quality corporate bonds available in the market place with maturities approximately equal to projected cash flows of future benefit payments as of the measurement date. Periodic benefit expense (or income) includes service costs and interest costs based on the assumed discount rate, amortization of prior service costs due to plan amendments and amortization of actuarial gains and losses. Service costs are included in salaries and employee benefits and all other costs are included in other noninterest expense. The amortization of actuarial gains and losses is determined using the 10% corridor minimum amortization approach and is taken over the average remaining future working lifetime of the plan participants. The underfunded status of the plans is recorded as a liability on the balance sheet.

The multiemployer pension plan’s assets are determined based on fair value, generally representing observable market prices. The actuarial cost method used to compute the pension liabilities and related expense is the unit credit method. The pension expense is equal to the plan contribution requirement of the Company for the plan year.

The Company maintains two frozen single employer pension plans. The Company accounts for these pension plans using an actuarial model that allocates pension costs over the service period of employees in the plan. The Company accounts for the over-funded or under-funded status of the pension plans as an asset or liability on its consolidated balance sheets and recognizes changes in the funded status that are not reflected in net periodic pension cost as other comprehensive income or loss.

The Director Deferred Compensation Plan allows directors to invest their funds into a diversified investment portfolio and the 401(k) Restoration Plan allows employees to invest their funds in both Company stock and other investment alternatives offered by the Plan. All funds under both of these plans are held in a rabbi trust. The plans do not permit diversification after initial election and therefore elections made to defer into Company stock result in both the investment and
obligation recognized within Stockholders’ Equity. Alternatively, investments not in Company stock are included in trading securities, with the correlating obligation classified as a liability.
The Company has obligations with various individuals related to certain post-retirement benefits. The obligations are based on the individual’s service through retirement, with the associated cost recognized over the requisite service period. The accrual methodology results in an accrued amount at the full eligibility date equal to the then present value of all of the future benefits expected to be paid.
STOCK-BASED COMPENSATION
Stock-Based Compensation

The Company recognizes stock-based compensation based on the grant-date fair value of the award, with no adjustment for estimated forfeitures, as forfeitures are recognized when they occur. For restricted stock awards and units, the Company recognizes compensation expense ratably over the vesting period for the fair value of the award, measured at the grant date. For stock option awards, the Company values awards granted using the Black-Scholes option-pricing model. The Company recognizes compensation expense for these awards on a straight-line basis over the requisite service period for the entire award (straight-line attribution method), ensuring that the amount of compensation cost recognized at any date at least equals the portion of the grant-date fair value of the award that is vested at that time. The Company recognizes excess tax benefits on certain stock compensation transactions. The excess tax benefits are recorded through earnings as a discrete item within the Company’s effective tax rate during the period of the transaction.
INCOME TAXES
Income Taxes

Deferred income tax assets and liabilities are determined using the asset and liability (or balance sheet) method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. If current available information raises doubt as to the realization of the deferred tax assets, a valuation allowance is established. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in enacted tax rates is recognized in income in the period that includes the enactment date. Income taxes are allocated to each entity in the consolidated group based on its share of taxable income. Management exercises significant judgment in evaluating the amount and timing of recognition of the resulting tax liabilities and assets, including projections of future taxable income. Additionally, a liability for unrecognized tax benefits is recorded for uncertain tax positions taken by the Company on its tax returns for which there is less than a 50% likelihood of being recognized upon a tax examination.
Low Income Housing Tax Credits Policy Text Block [Policy Text Block]
Low Income Housing Tax Credits
The Company accounts for its investments in qualified affordable housing projects using the proportional amortization method. Under the proportional amortization method the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received, and recognizes the net investment benefit as a component of income tax expense (benefit).
ASSETS UNDER ADMININSTRATION
Assets Under Administration

Assets held in a fiduciary or agency capacity for customers are not included in the accompanying consolidated balance sheet, as such assets are not assets of the Company. Revenue from administrative and management activities associated with these assets is recorded on an accrual basis.
Extinguishment of Debt [Policy Text Block]
Extinguishment of Debt

Upon extinguishment of an outstanding debt, the Company records the difference between the exit price and the net carrying amount of the debt as a gain or loss on the extinguishment. The gain or loss is recorded as a component of other noninterest income or other noninterest expense, respectively.
EARNINGS PER SHARE
Earnings Per Share

Basic earnings per share is calculated using the two-class method. The two-class method is an earnings allocation formula under which earnings per share is calculated from common stock and participating securities according to dividends declared and participation rights in undistributed earnings. Under this method, all earnings, distributed and undistributed, are
allocated to participating securities and common shares based on their respective rights to receive dividends. Unvested share-based payment awards that contain nonforfeitable rights to dividends are considered participating securities, not subject to performance based measures (i.e. unvested time-vested restricted stock). Basic earnings per share is calculated by dividing net income by the weighted average number of common shares outstanding (inclusive of participating securities). Diluted earnings per share have been calculated in a manner similar to that of basic earnings per share except that the weighted average number of common shares outstanding is increased to include the number of additional common shares that would have been outstanding if all potentially dilutive common shares (such as those resulting from the exercise of stock options or the attainment of performance measures) were issued during the period, computed using the treasury stock method.
COMPREHENSIVE INCOME
Comprehensive Income

Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, unrealized losses related to factors other than credit on debt securities, if applicable, unrealized gains and losses on cash flow hedges, deferred gains on hedge accounting transactions, and changes in the funded status of the Company’s postretirement and supplemental retirement plans.
FAIR VALUE MEASUREMENTS
Fair Value Measurements

In general, fair values of financial instruments are based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters.

Policy Loans Receivable, Policy
Loans Held for Investment    

Loans that the Company has the intent and ability to hold until maturity or payoff are carried at amortized cost (net of the allowance for credit losses). Amortized cost is the principal amount outstanding, adjusted by partial charge-offs and net of deferred loan costs or fees. For originated loans, loan fees and certain direct origination costs are deferred and amortized into interest income over the expected term of the loan using the level-yield method.  When a loan is paid off, the unamortized portion is recognized in interest income. Interest income on loans is accrued based upon the daily principal amount outstanding except for loans on nonaccrual status.

 As a general rule, loans 90 days or more past due with respect to principal or interest are classified as nonaccrual loans, or sooner if management considers such action to be prudent. However, loans that are 90 days or more past due may be kept on an accruing status if the loan is well secured and in the process of collection. Income accruals are suspended on all nonaccrual loans in a timely manner and all previously accrued and uncollected interest is reversed against current income. A loan remains on nonaccrual status until it becomes current with respect to principal and interest and remains current for a minimum period of six months, the loan is liquidated, or when the loan is determined to be uncollectible and is charged-off against the allowance for credit losses. When doubt exists as to the collectability of a loan, any payments received are applied to reduce the amortized cost of the loan to the extent necessary to eliminate such doubt. For all loan portfolios, a charge-off occurs when the Company determines that a specific loan, or portion thereof, is uncollectible.  This determination is made based on management’s review of specific facts and circumstances of the individual loan, including assessing the viability of the customer’s business or project as a going concern, the expected cash flows to repay the loan, the value of the collateral and the ability and willingness of any guarantors to perform. 

In the course of resolving problem loans, the Company may choose to modify the contractual terms of certain loans. The Company attempts to work out an alternative payment schedule with the borrower in order to avoid or cure a default. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status and may include adjustments to term extensions, interest rates, other than insignificant payment delays and/or a combination thereof. These
actions are intended to minimize economic loss and avoid foreclosure or repossession of collateral. If such efforts by the Bank do not result in satisfactory performance, the loan is referred to legal counsel, at which time foreclosure proceedings are initiated. At any time prior to a sale of the property at foreclosure, the Bank may terminate foreclosure proceedings if the borrower is able to work out a satisfactory payment plan. Any loans that are modified are reviewed by the Company to determine whether the modification is the direct result of a borrower experiencing financial difficulty, as the Company adopted the accounting and disclosure requirements for loan modifications made to borrowers experiencing financial difficulty and ceased to recognize troubled debt restructurings (“TDRs”) effective January 1, 2023. Prior to this adoption, the Company would classify loans as TDRs in cases where a borrower was experiencing financial difficulty and where the Company made certain concessionary modifications to contractual terms. Modifications included adjustments to interest rates, extensions of maturity, consumer loans where the borrower’s obligations had been effectively discharged through Chapter 7 Bankruptcy and the borrower had not reaffirmed the debt to the Bank, and other actions intended to minimize economic loss and avoid foreclosure or repossession of collateral. Under the previously applicable guidance, loans classified as TDRs would have remained classified as such for the life of the loan, except in limited circumstances, when it was determined that the borrower was performing under the modified terms and the restructuring agreement specified an interest rate greater than or equal to an acceptable market rate for a comparable new loan at the time of the restructuring.
Credit Loss, Financial Instrument
Allowance for Credit Losses - Loans Held for Investment

The allowance for credit losses is established based upon the Company’s current estimate of expected lifetime credit losses on loans measured at amortized cost, also referred to as the CECL methodology. Credit losses are charged against the allowance when management’s assessments confirm that the Company will not collect the full amortized cost basis of a loan. Subsequent recoveries, if any, are credited to the allowance.

Under the CECL methodology, the Company estimates credit losses for financial assets on a collective basis for loans sharing similar risk characteristics using a quantitative model combined with an assessment of certain qualitative factors designed to address forecast risk and model risk inherent in the quantitative model output. The quantitative model utilizes a factor-based approach to estimate expected credit losses using Probability of Default (“PD”), Loss Given Default (“LGD”) and Exposure at Default (“EAD”), which are derived from internal historical default and loss experience. The model estimates expected credit losses using loan level data over the estimated life of the exposure, considering the effect of prepayments. Economic forecasts are incorporated into the estimate over a reasonable and supportable forecast period, beyond which is a reversion to the Company’s historical long-run average. Management has determined a reasonable and supportable period of 12 months, and a straight line reversion period of 6 months, to be appropriate for purposes of estimating expected credit losses. The qualitative risk factors impacting the expected risk of loss within the portfolio include the following:

Lending policies and procedures
Economic and business conditions
Nature and volume of loans
Changes in management
Changes in credit quality
Changes in loan review system
Changes to underlying collateral values
Concentrations of credit risk
Other external factors
Model imprecision

Loans that do not share similar risk characteristics with any pools of assets are subject to individual evaluation and are removed from the collectively assessed pools to avoid double counting. For the loans that are individually evaluated, the Company uses either a discounted cash flow (“DCF”) approach or a fair value of collateral approach. The latter approach is used for loans deemed to be collateral dependent or when foreclosure is probable.

Loan modifications made to borrowers experiencing financial difficulty are evaluated on a collective basis with loans sharing similar risk characteristics in accordance with the CECL methodology. Under previously applicable accounting guidance, the Company determined the amount of allowance for credit losses on TDRs using a discounted cash flow analysis or
a fair value of collateral approach if the loan was determined to be individually evaluated. This change in methodology did not have a material impact on the Company’s allowance for credit loss estimate.

Accrued interest receivable amounts are excluded from balances of loans held at amortized cost and are included within other assets on the Consolidated Balance Sheets. Management has elected not to measure an allowance for credit losses on these amounts as the Company employs a timely write-off policy. Consistent with the Company’s policy for nonaccrual loans, accrued interest receivable is typically written off when loans reach 90 days past due and are placed on nonaccrual status.

Allowance for Credit Losses - Unfunded Lending Commitments

In the ordinary course of business, the Company enters into commitments to extend credit, commercial letters of credit, and standby letters of credit. The allowance for credit losses on these unfunded loan commitments provides for potential exposure inherent with the funding of unused portions on legal commitments that are not unconditionally cancellable by the Company. Management evaluates the need for a reserve on unfunded lending commitments in a manner consistent with loans held for investment. The reserve for unfunded lending commitments is included in other liabilities on the Consolidated Balance Sheets.

Acquired Loans

Loans acquired through purchase or a business combination are recorded at their fair value at the acquisition date. The Company performs an assessment of acquired loans to first determine if such loans have experienced a more than insignificant deterioration in credit quality since their origination and thus should be classified and accounted for as PCD loans. For loans that have not experienced a more than insignificant deterioration in credit quality since origination, referred to as non-PCD loans, the Company records such loans at fair value, with any resulting discount or premium accreted or amortized into interest income over the remaining life of the loan using the interest method. Additionally, upon the purchase or acquisition of non-PCD loans, the Company measures and records a reserve for credit losses based on the Company’s methodology for determining the allowance under CECL. The allowance for non-PCD loans is recorded through a charge to provision for credit losses in the period in which the loans were purchased or acquired.

Acquired loans that are classified as PCD are acquired at fair value, including any resulting discounts or premiums. Discounts and premiums are accreted or amortized into interest income over the remaining life of the loan using the interest method. In contrast to non-PCD loans, the initial allowance for credit losses on PCD loans is established through an adjustment to the acquired loan balance, rather than through a charge to provision for credit losses, in the period in which the loans were acquired. The allowance for PCD loans is determined based upon the Company’s methodology for estimating the allowance under CECL, and is recorded as an adjustment to the acquired loan balance on the date of acquisition. The Company evaluates acquired loans for deterioration in credit quality based on a variety of characteristics, including, but not limited to non-accrual and delinquency status, downgrades in credit quality since origination, loans that have been modified, along with any other factors identified by the Company through its initial analysis of acquired loans which may indicate there has been a more than insignificant deterioration in credit quality since origination. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics, if applicable.

Subsequent to acquisition, the allowances for credit losses for both non-PCD and PCD loans are determined with the use of the Company’s allowance methodology under CECL, in the same manner as all other loans.

Transfers and Servicing of Financial Assets
    
Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Loans held for sale are generally sold with servicing rights released, however if rights are retained, servicing assets are recognized as separate assets. Servicing rights are originally recorded at fair value within other assets, but subsequently are amortized in proportion to and over the period of estimated net servicing income, and are assessed for impairment at each reporting date. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, the custodial earnings rate, an inflation rate, ancillary income, prepayment speeds, default rates and losses. Impairment is determined by stratifying the rights based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance, to the extent that fair value is less than the capitalized amount. If the Company later determines that all or a portion of the impairment no longer exists, a reduction of the allowance may be recorded as an increase to income.

Servicing fee income is recorded for fees earned for servicing loans for investors. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan, and are recorded as income when earned. The amortization of mortgage servicing rights is recorded as a reduction of loan servicing fee income.

The Company is also a party to certain instruments with off-balance-sheet risk including certain residential loans sold to investors with recourse. The Company’s policy is to record such instruments when funded.
Commercial Portfolio
Commercial and Industrial: Consists of revolving, non-revolving, and term loan obligations extended to business and corporate enterprises for the purpose of financing working capital and/or capital investment, as well as loans to finance owner-occupied commercial properties.  Collateral generally consists of accounts receivable, inventory, plant and equipment, real estate, or other business assets. The primary source of repayment is operating cash flow and, secondarily, liquidation of assets.
Commercial Real Estate: Consists of mortgage loans to finance investment in real property such as multi-family residential, commercial/retail, office, industrial, hotels, educational and healthcare facilities, as well as other specific use properties and is inclusive of non-owner-occupied commercial properties.  Loans are typically written with amortizing payment structures.  Collateral values are determined based upon third party appraisals and evaluations.  Permissible loan to value ratios at origination are governed by Company policy and regulatory guidelines. The primary source of repayment is cash flow from operating leases and rents and, secondarily, liquidation of assets.
Commercial Construction: Consists of short-term construction loans, revolving and nonrevolving credit lines and construction/permanent loans to finance the acquisition, development and construction or rehabilitation of real property.  Project types include residential land development, one-to-four family, condominium, and multi-family home construction, commercial/retail, office, industrial, hotels, educational and healthcare facilities as well as other specific use properties.  Loans may be written with nonamortizing or hybrid payment structures depending upon the type of project.  Collateral values are determined based upon third party appraisals and evaluations.  Permissible loan to value ratios at origination are governed by Company policy and regulatory guidelines.  Repayment sources vary depending upon the type of project and may consist of proceeds from the sale or lease of units, operating cash flows or liquidation of other assets.
Small Business: Consists of revolving, term loan and mortgage obligations extended to sole proprietors and small businesses for purposes of financing working capital and/or capital investment.  Collateral generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant and equipment, or real estate if applicable.  The primary source of repayment is operating cash flows and, secondarily, liquidation of assets.
For the commercial portfolio the Company typically obtains personal guarantees for payment from individuals holding material ownership interests in the borrowing entities.
Consumer Portfolio
Residential Real Estate: Residential mortgage loans held in the Company’s portfolio are made to borrowers who demonstrate the ability to make scheduled payments with full consideration to underwriting factors such as current and expected income, employment status, current assets, other financial resources, credit history and the value of the collateral.  Collateral consists of mortgage liens on one-to-four family residential properties.  Residential mortgage loans also include loans to construct owner-occupied one-to-four family residential properties.
Home Equity: Home equity loans and credit lines are made to qualified individuals and are primarily secured by senior or junior mortgage liens on one-to-four family homes, condominiums or vacation homes. Each home equity loan has a fixed rate and is billed in equal payments comprised of principal and interest. The majority of home equity lines of credit have a variable rate and are billed in interest-only payments during the draw period. At the end of the draw period, the home equity line of credit is billed as a percentage of the then outstanding principal balance plus all accrued interest over a predetermined repayment period, as set forth in the note. Additionally, the Company has the option of renewing each line of credit for additional draw periods.  Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan to value ratios within established policy guidelines.
Other Consumer: Other consumer loan products include personal lines of credit and amortizing loans made to qualified individuals for various purposes such as debt consolidation, personal expenses or overdraft protection.  Borrower qualifications include favorable credit history combined with supportive income and collateral requirements within established policy guidelines.  These loans may be secured or unsecured.

(1)The carrying value of individually assessed collateral dependent loans is based on the lower of amortized cost or fair value of the underlying collateral less costs to sell. The fair value of the underlying collateral is generally determined through independent appraisals, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

(a)The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analysis.
(b)Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.
(c)Federal Home Loan Bank stock has no quoted market value and is carried at cost, therefore the carrying amount approximates fair value.
(d)Cash surrender value of life insurance is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.
(e)Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.
(f)Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.
(g)Fair value was determined based upon market prices of securities with similar terms and maturities.

[1] The carrying value of individually assessed collateral dependent loans is based on the lower of amortized cost or fair value of the underlying collateral less costs to sell. The fair value of the underlying collateral is generally determined through independent appraisals, which generally include various Level 3 inputs which are not identifiable. Appraisals may be adjusted by management for qualitative factors such as economic factors and estimated liquidation expenses. The range of these possible adjustments may vary.

[1] Fair value of loans is measured using the exit price valuation method, determined primarily by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities or cash flows, while incorporating liquidity and credit assumptions. Additionally, this amount excludes individually assessed collateral dependent loans, which are deemed to be marked to fair value on a nonrecurring basis.
[2] Fair value of demand deposits, savings and interest checking accounts and money market deposits is the amount payable on demand at the reporting date.
[3] Fair value was determined by discounting anticipated future cash payments using rates currently available for instruments with similar remaining maturities.
[4] Fair value was determined based upon market prices of securities with similar terms and maturities.
[5] The fair values presented are based on quoted market prices, where available. If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments and/or discounted cash flow analysis.
[6] Federal Home Loan Bank stock has no quoted market value and is carried at cost, therefore the carrying amount approximates fair value.
[7] Cash surrender value of life insurance is recorded at its cash surrender value (or the amount that can be realized upon surrender of the policy), therefore, carrying amount approximates fair value.
