Accounting Policies [Abstract]  
Accounting Policies ACCOUNTING POLICIES
The accounting and reporting policies and practices of Independent Bank Corporation and subsidiaries (‘‘IBCP’’) conform to accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. Our critical accounting policies include the determination of the allowance for credit losses and the valuation of capitalized mortgage loan servicing rights. We are required to make material estimates and assumptions that are particularly susceptible to changes in the near term as we prepare the consolidated financial statements and report amounts for each of these items. Actual results may vary from these estimates.
Our subsidiary, Independent Bank (‘‘Bank’’), transacts business in the single industry of commercial banking. Our Bank’s activities cover traditional phases of commercial banking, including checking and savings accounts, commercial lending, direct and indirect consumer financing and mortgage lending. Our principal markets are the rural and suburban communities across Lower Michigan that are served by our Bank’s branches and loan production offices as well as one loan production facility in Ohio. At December 31, 2024, 72.1% of our Bank’s loan portfolio was secured by real estate.
PRINCIPLES OF CONSOLIDATION — The consolidated financial statements include the accounts of Independent Bank Corporation and its subsidiaries. The income, expenses, assets and liabilities of the subsidiaries are included in the respective accounts of the consolidated financial statements, after elimination of all intercompany accounts and transactions.
USE OF ESTIMATES — To prepare financial statements in conformity with accounting principles generally accepted in the United States of America management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the consolidated financial statements and the disclosures provided, and actual results could differ.
STATEMENTS OF CASH FLOWS — For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits and federal funds sold. Generally, federal funds are sold for one-day periods. We report net cash flows for customer loan and deposit transactions and for short-term borrowings.
INTEREST BEARING DEPOSITS — Interest bearing deposits consist of overnight deposits with the Federal Reserve Bank.
LOANS HELD FOR SALE — Mortgage loans originated and intended for sale in the secondary market are carried at fair value. Fair value adjustments, as well as realized gains and losses, are recorded in current earnings.
OPERATING SEGMENTS — While chief decision-makers monitor the revenue streams of our various products and services, operations are managed and financial performance is evaluated as one single unit. Discrete financial information is not available other than on a consolidated basis for material lines of business.
CAPITALIZED MORTGAGE LOAN SERVICING RIGHTS — We account for our capitalized mortgage loan servicing rights under the fair value method of accounting. We recognize as separate assets the rights to service mortgage loans for others. The fair value of capitalized mortgage loan servicing rights has been determined based upon fair value indications for similar servicing. Under the fair value method we measure capitalized mortgage loan servicing rights at fair value at each reporting date and report changes in fair value of capitalized mortgage loan servicing rights in earnings in the period in which the changes occur and are included in mortgage loan servicing, net in the Consolidated Statements of Operations. The fair value of capitalized mortgage loan servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.
Mortgage loan servicing income is recorded for fees earned for servicing loans previously sold. The fees are generally based on a contractual percentage of the outstanding principal and are recorded as income when earned. Mortgage loan servicing fees, excluding fair value changes of capitalized mortgage loan servicing rights, totaled $8.9 million, $8.8 million and $8.6 million for the years ended December 31, 2024, 2023 and 2022, respectively. Late fees and ancillary fees related to loan servicing are not material.
TRANSFERS OF FINANCIAL ASSETS — Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from us, 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 we do not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
SECURITIES — We classify our securities as equity, trading, held to maturity ("HTM") or available for sale ("AFS"). Equity securities are investments in certain equity stocks and are reported at fair value with realized and unrealized gains and losses included in earnings. Trading securities are bought and held principally for the purpose of selling them in the near term and are reported at fair value with realized and unrealized gains and losses included in earnings. Securities HTM represent those securities for which we have the positive intent and ability to hold until maturity and are reported at cost, adjusted for amortization of premiums and accretion of discounts computed on the level-yield method. During 2022 we transferred certain securities AFS with an amortized cost and unrealized loss at the date of transfer of $418.1 million and $26.5 million, respectively to HTM. See note #3 for further discussion of this transfer. We did not have any equity securities or trading securities at December 31, 2024 and 2023. Securities AFS represent those securities not classified as equity, trading or held to maturity and are reported at fair value with unrealized gains and losses, net of applicable income taxes reported in other comprehensive income (loss).
Securities AFS in unrealized loss positions are evaluated quarterly for impairment related to credit losses. For securities AFS in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities AFS that do not meet this criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, we consider the extent to which fair value is less than amortized cost, adverse conditions specifically related to the security and the issuer and the impact of changes in market interest rates on the market value of the security, among other factors. If this assessment indicates that a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses ("ACL") is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income (loss), net of applicable taxes.
The ACL on securities HTM is a contra asset valuation account that is deducted from the carrying amount of securities HTM to present the net amount expected to be collected. Securities HTM are charged off against the ACL when deemed uncollectible. Adjustments to the ACL are reported in our Consolidated Statements of Operations in provision for credit losses. We measure expected credit losses on securities HTM on a collective basis by major security type with each type sharing similar risk characteristics, and we consider historical credit loss information. Accrued interest receivable on securities HTM is excluded from the estimate of credit losses. With regard to U.S. Government-sponsored agency and mortgage-backed securities (residential and commercial), all these securities are issued by a U.S. government-sponsored entity and have an implicit or explicit government guarantee; therefore, no allowance for credit losses has been recorded for these securities. With regard to obligations of states and political subdivisions, private label-mortgage-backed, corporate and trust preferred securities HTM, we consider (1) issuer bond ratings, (2) long-term historical loss rates for given bond ratings, (3) the financial condition of the issuer, and (4) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities.
Gains and losses realized on the sale of securities available for sale are determined using the specific identification method and are recognized on a trade-date basis.
FEDERAL HOME LOAN BANK (‘‘FHLB’’) STOCK — Our Bank subsidiary is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income in interest income-other investments on the Consolidated Statements of Operations.
FEDERAL RESERVE BANK (‘‘FRB’’) STOCK — Our Bank subsidiary is a member of its regional Federal Reserve Bank. FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income in interest income-other investments on the Consolidated Statements of Operations.
LOAN REVENUE RECOGNITION — Interest on loans is accrued based on the principal amounts outstanding. In general, the accrual of interest income is discontinued when a loan becomes 90 days past due for commercial loans and installment loans and when a loan misses four consecutive payments for mortgage loans and the borrower’s capacity to repay the loan and collateral values appear insufficient for each loan class. However, loans may be placed on non-accrual status regardless of whether or not such loans are considered past due if, in management’s opinion, the borrower is unable to meet payment obligations as they become due or as required by regulatory provisions. All interest accrued but not received for all loans placed on non-accrual is reversed from interest income. Payments on such loans are generally applied to the principal balance until qualifying to be returned to accrual status. A non-accrual loan may be restored to accrual status when interest and principal payments are current and the loan appears otherwise collectible. Delinquency status for all classes in the commercial and installment loan portfolio segments is based on the actual number of days past due as required by the contractual terms of the loan agreement while delinquency status for mortgage loan portfolio segment classes is based on the number of payments past due.
Certain loan fees and direct loan origination costs are deferred and recognized as an adjustment of yield generally over the contractual life of the related loan. Fees received in connection with loan commitments are deferred until the loan is advanced and are then recognized generally over the contractual life of the loan as an adjustment of yield. Fees on commitments that expire unused are recognized at expiration. Fees received for letters of credit are recognized as revenue over the life of the commitment.
ALLOWANCE FOR CREDIT LOSSES — Our loan portfolio is disaggregated into segments for purposes of determining the ACL which include commercial, mortgage and installment loans. These segments are further disaggregated into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within the commercial loan segment include (i) commercial and industrial and (ii) commercial real estate. Classes within the mortgage loan segment include (i) 1-4 family owner occupied - jumbo, (ii) 1-4 family owner occupied - non-jumbo, (iii) 1-4 family non-owner occupied (iv) 1-4 family - 2nd lien and (v) resort lending. Classes within the installment loan segment include (i) boat lending, (ii) recreational vehicle lending, and (iii) other. Commercial loans are subject to adverse market conditions which may impact the borrower’s ability to make repayment on the loan or could cause a decline in the value of the collateral that secures the loan. Mortgage and installment loans are subject to adverse employment conditions in the local economy which could increase default rates. In addition, mortgage loans and real estate based installment loans are subject to adverse market conditions which could cause a decline in the value of collateral that secures the loan. For an analysis of the ACL by portfolio segment and credit quality information by class, see note #4.
We estimate the ACL based on relevant available information from both internal and external sources, including historical loss trends, current conditions and forecasts, specific analysis of individual loans, and other relevant and appropriate factors. The allowance process is designed to provide for expected future losses based on our reasonable and supportable (“R&S”) forecast as of the reporting date. Our ACL process is administered by our Risk Management group utilizing a third party software solution, with significant input and ultimate approval from our Executive Enterprise Risk Committee. Further, we have established a current expected credit loss (“CECL”) Forecast Committee, which includes a cross discipline structure with membership from Executive Management, Risk Management, Credit Administration and Accounting, which approves ACL model assumptions each quarter. Our ACL is comprised of three principal elements: (i) specific analysis of individual loans identified during the review of the loan portfolio, (ii) pooled analysis of loans with similar risk characteristics based on historical experience, adjusted for current conditions, R&S forecasts, and expected prepayments, and (iii) additional allowances based on subjective factors, including local and general economic business factors and trends, portfolio concentrations and changes in the size and/or the general terms of the loan portfolio.
The first ACL element (specific allocations) includes loans that do not share similar risk characteristics and are evaluated on an individual basis. We will typically evaluate on an individual basis loans that are on nonaccrual; commercial loans that have been modified resulting in a concession, for which the borrower is experiencing financial difficulties, and which are considered troubled loan modifications or with well defined weaknesses; and severely delinquent mortgage and installment loans. When we determine that foreclosure is probable or when repayment is expected to be provided substantially through the operation or sale of underlying collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for estimated selling costs. For loans evaluated on an individual basis that are not determined to be collateral dependent, a discounted cash flow analysis is performed to determine expected credit losses.
The second ACL element (pooled analysis) includes loans with similar risk characteristics, which are broken down by segment, class, and risk metric. The Bank’s primary segments of commercial, mortgage, and installment loans are further
classified by other relevant attributes, such as collateral type, lien position, occupancy status, amortization method, and balance size. Commercial classes are additionally segmented by risk rating, and mortgage and installment loan classes by credit score tier, which are updated at least semi-annually.
We utilize a discounted cash flow (“DCF”) model to estimate expected future losses for pooled loans. Expected future cash flows are developed from payment schedules over the contractual term, adjusted for forecasted default (probability of default), loss, and prepayment assumptions. We are not required to develop forecasts over the full contractual term of the financial asset or group of financial assets. Rather, for periods beyond which we are able to make or obtain R&S forecasts of expected credit losses, we revert to the long term average on a straight line or immediate basis, as determined by our CECL Forecast Committee, and which may vary depending on the economic outlook and uncertainty.
The DCF model for the mortgage and installment pooled loan segments includes using probability of default (“PD”) assumptions that are derived through regression analysis with forecasted US unemployment levels by credit score tier. We review a composite forecast of approximately 50 analysts as well as the Federal Open Market Committee (“FOMC”) projections in setting the unemployment forecast for the R&S period. The current ACL utilizes a one year R&S forecast followed by immediate reversion to the 75 year average unemployment rate. PD assumptions for the remaining segments are based primarily on historical rates by risk metric as defaults were not strongly correlated with any economic indicator. Loss given default (“LGD”) assumptions for the mortgage loan segment are based on a two year forecast followed by a two year straight line reversion period to the longer term average, while LGD rates for the remaining segments are the historical average for the entire period. Prepayment assumptions represent average rates per segment for a period determined by the CECL Forecast Committee and as calculated through the Bank’s Asset and Liability Management program.
Pooled reserves for the commercial loan segment are calculated using the DCF model with assumptions generally based on historical averages by class and risk rating. Effective risk rating practices allow for strong predictability of defaults and losses over the portfolio’s expected shorter duration, relative to mortgage and installment loans. Our rating system is similar to those employed by state and federal banking regulators.
The third ACL element (additional allocations based on subjective factors) is based on factors that cannot be associated with a specific credit or loan category and reflects our attempt to ensure that the overall ACL appropriately reflects a margin for the imprecision necessarily inherent in the estimates of expected credit losses. We adjust our quantitative model for certain qualitative factors to reflect the extent to which management expects current conditions and R&S forecasts to differ from the conditions that existed for the period over which historical information was evaluated. The qualitative framework reflects changes related to relevant data, such as changes in asset quality trends, portfolio growth and composition, national and local economic factors, credit policy and administration and other factors not considered in the base quantitative model. We utilize a survey completed by business unit management throughout the Bank, as well as discussion with the CECL Forecast Committee to establish reserves under the qualitative framework.
Increases in the ACL are recorded by a provision for credit losses charged to expense. Although we periodically allocate portions of the ACL to specific loans and loan portfolios, the entire ACL is available for losses.
We generally charge-off commercial, homogenous residential mortgage and installment loans when they are deemed uncollectible or reach a predetermined number of days past due based on loan product, industry practice and other factors. Collection efforts may continue and recoveries may occur after a loan is charged against the ACL.
While we use relevant information to recognize losses on loans, additional provisions for related losses may be necessary based on changes in economic conditions, customer circumstances and other credit risk factors.
PROPERTY AND EQUIPMENT — Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the related assets. Buildings are generally depreciated over a period not exceeding 39 years and equipment is generally depreciated over periods not exceeding 7 years. Leasehold improvements are depreciated over the shorter of their estimated useful life or lease period.
BANK OWNED LIFE INSURANCE — We have purchased a group flexible premium non-participating variable life insurance contract on approximately 253 lives (who were salaried employees at the time we purchased the contract) in order to recover the cost of providing certain employee benefits. Bank owned life insurance is recorded at its cash surrender value or the amount that can be currently realized.
OTHER REAL ESTATE AND REPOSSESSED ASSETS — Other real estate at the time of acquisition is recorded at fair value, less estimated costs to sell, which becomes the property’s new basis. Fair value is typically determined by a third party appraisal of the property. Any write-downs at date of acquisition are charged to the ACL. Expense incurred in maintaining other real estate and subsequent write-downs to reflect declines in value and gains or losses on the sale of other real estate are recorded in non-interest expense in the Consolidated Statements of Operations. Non-real estate repossessed assets are treated in a similar manner.
OTHER INTANGIBLES — Other intangible assets consist of core deposits. They are initially measured at fair value and then are amortized on both straight-line and accelerated methods over their estimated useful lives, which range from 10 to 15 years.
GOODWILL — Goodwill arises from business combinations and is generally determined as the excess of the fair value of the consideration transferred over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill acquired in a purchase business combination and determined to have an indefinite useful life is not amortized, but tested for impairment at least annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. We have selected December 31 as the date to perform the annual impairment test. Goodwill is the only intangible asset with an indefinite life on our Consolidated Statements of Financial Condition.
INCOME TAXES — We employ the asset and liability method of accounting for income taxes. This method establishes deferred tax assets and liabilities for the temporary differences between the financial reporting basis and the tax basis of our assets and liabilities at tax rates expected to be in effect when such amounts are realized or settled. Under this method, the effect of a change in tax rates is recognized in the period that includes the enactment date. The deferred tax asset is subject to a valuation allowance for that portion of the asset for which it is more likely than not that it will not be realized.
A tax position is recognized as a benefit only if it is ‘‘more likely than not’’ that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination.
We recognize interest and/or penalties related to income tax matters in income tax expense in the Consolidated Statements of Operations.
We file a consolidated federal income tax return. Intercompany tax liabilities are settled as if each subsidiary filed a separate return.
COMMITMENTS TO EXTEND CREDIT AND RELATED FINANCIAL INSTRUMENTS — Financial instruments may include commitments to extend credit and standby letters of credit. Financial instruments involve varying degrees of credit and interest-rate risk in excess of amounts reflected in the Consolidated Statements of Financial Condition. Exposure to credit risk in the event of non-performance by the counterparties to the financial instruments for loan commitments to extend credit and letters of credit is represented by the contractual amounts of those instruments. In general, we use a similar methodology to estimate our liability for these off-balance sheet credit exposures as we do for our ACL. For commercial related commitments, we estimate liability using our loan rating system and for mortgage and installment commitments we estimate liability principally upon historical loss experience. Our estimated liability for off balance sheet commitments is included in accrued expenses and other liabilities in our Consolidated Statements of Financial Condition and any charge or recovery is recorded in non-interest expense – costs related to unfunded lending commitments in our Consolidated Statements of Operations.
DERIVATIVE FINANCIAL INSTRUMENTS — We record derivatives on our Consolidated Statements of Financial Condition as assets and liabilities measured at their fair value. The accounting for increases and decreases in the value of derivatives depends upon the use of derivatives and whether the derivatives qualify for hedge accounting.
At the inception of the derivative we designate the derivative as one of three types based on our intention and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (‘‘Fair Value Hedge’’), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (‘‘Cash Flow Hedge’’), or (3) an instrument with no hedging designation. For a Fair Value Hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the
hedged item, are recognized in interest income in our Consolidated Statements of Operations. For a Cash Flow Hedge, the gain or loss on the derivative is reported in other comprehensive income (loss) and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For instruments with no hedging designation, the gain or loss on the derivative is reported in earnings. These free standing instruments primarily consist of (i) mortgage banking related derivatives and include rate-lock loan commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and mandatory forward commitments for the future delivery of these mortgage loans and (ii) certain pay-fixed and pay-variable interest rate swap agreements related to commercial loan customers. The fair value of rate-lock mortgage loan commitments is based on agency cash window loan pricing for comparable assets and the fair value of mandatory commitments to sell mortgage loans is based on mortgage backed security pricing for comparable assets. We enter into mandatory forward commitments for the future delivery of mortgage loans generally when interest rate locks are entered into in order to hedge the change in interest rates resulting from our commitments to fund the loans. Changes in the fair values of these derivatives are included in net gains on mortgage loans in the Consolidated Statements of Operations. Fair values of the pay-fixed and pay-variable interest rate swap agreements are derived from proprietary models which utilize current market data and are included in net interest income in the Consolidated Statements of Operations.
Net cash settlements on derivatives that qualify for hedge accounting are recorded in net interest income in the Consolidated Statements of Operations. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income (mortgage banking related derivatives) or net interest income (interest rate swap agreements) in the Consolidated Statements of Operations. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged.
We formally document the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking Fair Value or Cash Flow Hedges to specific assets and liabilities on the Consolidated Statements of Financial Condition or to specific firm commitments or forecasted transactions. We discontinue hedge accounting when it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended.
When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded in earnings. When a Fair Value Hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a Cash Flow Hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income (loss) are amortized into earnings over the same periods which the hedged transactions will affect earnings.
COMPREHENSIVE INCOME (LOSS) — Comprehensive income (loss) consists of net income and unrealized gains and losses, net of tax, on securities available for sale and derivative instruments classified as cash flow hedges.
NET INCOME PER COMMON SHARE — Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period and participating share awards. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. For diluted net income per common share, net income is divided by the weighted average number of common shares outstanding during the period plus the assumed exercise of stock options, performance share units and stock units for a deferred compensation plan for non-employee directors.
SHARE BASED COMPENSATION — Cost is recognized for non-vested share awards issued to employees based on the fair value of these awards at the date of grant. A simulation analysis which considers potential outcomes for a large number of independent scenarios is utilized to estimate the fair value of performance share units and the market price of our common stock at the date of grant is used for other non-vested share awards. Cost is recognized over the required service period, generally defined as the vesting period. Forfeitures are recognized as they occur. Cost is also recognized for stock issued to non-employee directors. These shares vest immediately and cost is recognized during the period they are issued.
COMMON STOCK — At December 31, 2024, 0.1 million shares of common stock were reserved for issuance under the dividend reinvestment plan, 0.4 million shares of common stock were reserved for issuance under our long-term
incentive plan and 0.1 million shares of common stock were reserved for issuance under our non-employee director stock purchase plan.
RECLASSIFICATION — Certain amounts in the 2023 and 2022 consolidated financial statements have been reclassified to conform to the 2024 presentation.
ADOPTION OF NEW ACCOUNTING STANDARDS — In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04, ‘‘Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting’’ and in December 2022 the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848), Deferral of the Sunset Date of Topic 848". These new ASUs provide temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. Entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. Entities that make such elections would not have to remeasure contracts at the modification date or reassess a previous accounting determination. Entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met.
We had formed a cross-functional project team to lead the transition from LIBOR to a planned adoption of reference rates which included Secured Overnight Financing Rate (“SOFR”). We utilized the timeline guidance published by the Alternative Reference Rates Committee to develop and achieve internal milestones during the transitional period. We discontinued the use of new LIBOR-based loans as of December 31, 2021, according to regulatory guidelines. We also discontinued the use of new LIBOR based interest rate derivatives as of December 31, 2021. The amended guidance under Topic 848 and our ability to elect its temporary optional expedients and exceptions were effective for us through December 31, 2024.
In March, 2023, the FASB issued ASU 2023-02, "Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force)". This ASU expands the use of the proportional amortization method of accounting — currently allowed only for investments in low-income housing tax credit ("LIHTC") structures — to equity investments in other tax credit structures that meet certain criteria. Common tax credit programs that investors access via tax equity structures and that may now be eligible for application of the proportional amortization method include: new markets tax credits, historic rehabilitation tax credit programs, and renewable energy tax credit programs. This ASU takes effect in reporting periods beginning after December 15, 2023, with early adoption permitted. The adoption of this ASU on January 1, 2024, did not have a material impact on our Consolidated Financial Statements.
In November, 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures". This ASU enhances disclosures of significant segment expenses by requiring entities to disclose significant segment expenses regularly provided to the chief operating decision maker, extend certain annual disclosures to interim periods, and permit more than one measure of segment profit or loss to be reported under certain conditions. This ASU takes effect in reporting periods beginning after December 15, 2023, with early adoption permitted. The adoption of this ASU on January 1, 2024, did not have a material impact on the Consolidated Financial Statements.
In December, 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". This ASU modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). This ASU also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. This ASU takes effect in reporting periods beginning after December 15, 2024, with early adoption permitted. We do not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements.
In December, 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". This ASU requires public business entities to disaggregate certain expense captions into specific categories in disclosures within the footnotes to the financial statements. This ASU takes effect in annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We do not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements.

(1)Represents the remaining unrealized loss to be accreted on securities that were transferred from AFS to HTM on April 1, 2022.
On April 1, 2022, we transferred certain securities AFS with an amortized cost and unrealized loss at the date of transfer of $418.1 million and $26.5 million, respectively to HTM. The transfer was made at fair value, with the unrealized loss becoming part of the purchase discount which will be accreted over the remaining life of the securities. The other comprehensive loss component is separated from the remaining available for sale securities and is accreted over the
remaining life of the securities transferred. We have the ability and intent to hold all HTM securities until they mature, at which time we expect to receive full value for these securities.
Our investments’ gross unrealized losses and fair values for securities AFS aggregated by investment type and length of time that individual securities have been at a continuous unrealized loss position, at December 31 follows:

Securities AFS in unrealized loss positions are evaluated quarterly for impairment related to credit losses. For securities AFS in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell, the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities AFS that do not meet this criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, we consider the extent to which fair value is less than amortized cost, adverse conditions specifically related to the security and the issuer and the impact of changes in market interest rates on the market value of the security, among other factors. If this assessment indicates that a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an ACL is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income (loss), net of
applicable taxes. No ACL for securities AFS was needed at December 31, 2024 and 2023. Accrued interest receivable on securities AFS totaled $3.9 million and $4.6 million at December 31, 2024 and 2023, respectively and is excluded from the estimate of credit losses and is included in accrued income and other assets in the Consolidated Statements of Financial Condition.
U.S. agency, U.S. agency residential mortgage-backed and U.S. agency commercial mortgage backed securities — at December 31, 2024, we had 29 U.S. agency, 103 U.S. agency residential mortgage-backed and 10 U.S. agency commercial mortgage-backed securities whose fair value is less than amortized cost. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. The unrealized losses are largely attributed to widening spreads to Treasury bonds and/or an increase in interest rates since acquisition.
Private label mortgage backed, other asset backed and corporate securities — at December 31, 2024, we had 71 private label mortgage backed, 44 other asset backed, and 73 corporate securities whose fair value is less than amortized cost. The unrealized losses are primarily due to credit spread widening and/or an increase in interest rates since acquisition.
Obligations of states and political subdivisions — at December 31, 2024, we had 311 municipal securities whose fair value is less than amortized cost. The unrealized losses are primarily due to an increase in interest rates since acquisition.
Trust preferred securities — at December 31, 2024, we had one trust preferred security whose fair value is less than amortized cost. This trust preferred securities is a single issue security issued by a trust subsidiary of a bank holding company. The pricing of trust preferred securities has suffered from credit spread widening. This security is rated by a major rating agency as investment grade.
At December 31, 2024 management does not intend to liquidate any of the securities discussed above and it is more likely than not that we will not be required to sell these securities prior to recovery of these unrealized losses.
We recorded no credit related charges in our Consolidated Statements of Operations related to securities available for sale during 2024, 2023, and 2022.
The ACL on securities HTM is a contra asset valuation account that is deducted from the carrying amount of securities HTM to present the net amount expected to be collected. Securities HTM are charged off against the ACL when deemed uncollectible. Adjustments to the ACL are reported in our Consolidated Statements of Operations in provision for credit losses. We measure expected credit losses on securities HTM on a collective basis by major security type with each type sharing similar risk characteristics and consider historical credit loss information. Accrued interest receivable on securities HTM totaled $1.7 million and $1.8 million at December 31, 2024 and 2023, respectively and is excluded from the estimate of credit losses and is included in accrued income and other assets in the Consolidated Statements of Financial Condition. With regard to U.S. Government-sponsored agency and mortgage-backed securities (residential and commercial), all these securities are issued by a U.S. government-sponsored entity and have an implicit or explicit government guarantee; therefore, no allowance for credit losses has been recorded for these securities. With regard to obligations of states and political subdivisions, private label-mortgage-backed, corporate and trust preferred securities HTM, we consider (1) issuer bond ratings, (2) historical loss rates for given bond ratings, (3) the financial condition of the issuer, and (4) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities. Historical loss rates associated with securities having similar grades as those in our portfolio have been insignificant. During the first quarter of 2023, one corporate security (Signature Bank) defaulted resulting in a $3.0 million provision for credit losses and a corresponding full charge-off. Subsequent to this security's charge-off, a portion of its fair value had recovered and was subsequently sold during the first quarter of 2024 for $1.1 million during which period we recorded that amount as a recovery to the ACL. Despite this lone security loss, the long-term historical loss rates associated with securities having similar grades as those in our portfolio have been insignificant. Furthermore, as of December 31, 2024 and 2023, there were no past due principal and interest payments associated with these securities. At those same dates an allowance for credit losses of $132,000 and $157,000, respectively was recorded on non U.S. agency securities HTM based on applying the long-term historical credit loss rate, as published by credit rating agencies, for similarly rated securities.
On a quarterly basis, we monitor the credit quality of securities HTM through the use of credit ratings. The carrying value of securities HTM at December 31, aggregated by credit quality follow:

If non-performing loans had continued to accrue interest in accordance with their original terms, approximately $0.3 million, $0.3 million and $0.2 million of interest income would have been recognized in each of the years ended 2024, 2023 and 2022, respectively. Interest income recorded on these loans was approximately zero during each of the years ended 2024, 2023 and 2022.
The following table provides collateral information by class of loan for collateral-dependent loans with a specific reserve.

For the year ended December 31, 2024 there were five mortgage - 1-4 family owner occupied - non-jumbo loans and one mortgage 1-4 family - 2nd lien loan modified as troubled loan modifications totaling $0.51 million (0.1% of the total
loan class) and $0.07 million (0.1% of the total loan class), respectively. All of the troubled loan modifications during the year ended December 31, 2024 involved term extensions and added a weighted average 7.1 years to the life of the loans.
One of the mortgage - 1-4 family owner occupied - non-jumbo loans modified during the year ended December 31, 2024 also received a 3.625% interest rate reduction.
Of the loans modified during the year ended December 31, 2024, two are on non-accrual status totaling $0.3 million. For the year ended December 31, 2023, there were no troubled loan modifications or subsequent defaults.
A loan is generally considered to be in payment default once it is 90 days contractually past due under the modified terms for commercial loans and installment loans and when four consecutive payments are missed for mortgage loans.
In order to determine whether a borrower is experiencing financial difficulty, we perform an evaluation of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under our internal underwriting policy.
Credit Quality Indicators – As part of our on-going monitoring of the credit quality of our loan portfolios, we track certain credit quality indicators including (a) risk grade of commercial loans, (b) the level of classified commercial loans, (c) credit scores of mortgage and installment loan borrowers, and (d) delinquency history and non-performing loans.
For commercial loans, we use a loan rating system that is similar to those employed by state and federal banking regulators. Loans are graded on a scale of 1 to 12. A description of the general characteristics of the ratings follows:
Rating 1 through 6: These loans are generally referred to as our ‘‘non-watch’’ commercial credits that include very high or exceptional credit fundamentals through acceptable credit fundamentals.
Rating 7 and 8: These loans are generally referred to as our ‘‘watch’’ commercial credits. These ratings include loans to borrowers that exhibit potential credit weakness or downward trends. If not checked or cured these trends could weaken our asset or credit position. While potentially weak, no loss of principal or interest is envisioned with these ratings.
Rating 9: These loans are generally referred to as our ‘‘substandard accruing’’ commercial credits. This rating includes loans to borrowers that exhibit a well-defined weakness where payment default is probable and loss is possible if deficiencies are not corrected. Generally, loans with this rating are considered collectible as to both principal and interest primarily due to collateral coverage.
Rating 10 and 11: These loans are generally referred to as our ‘‘substandard - non-accrual’’ and ‘‘doubtful’’ commercial credits. These ratings include loans to borrowers with weaknesses that make collection of the loan in full, on the basis of current facts, conditions and values at best questionable and at worst improbable. All of these loans are placed in non-accrual.
Rating 12: These loans are generally referred to as our ‘‘loss’’ commercial credits. This rating includes loans to borrowers that are deemed incapable of repayment and are charged-off.

If we do not remain well capitalized for regulatory purposes (see note #20), meet certain minimum capital levels or certain profitability requirements or if we incur a rapid decline in net worth, we could lose our ability to sell and/or service loans to these investors. This could impact our ability to generate net gains on mortgage loans and generate servicing income. A forced liquidation of our servicing portfolio could also impact the value that could be recovered on this asset. Fannie Mae has the most stringent eligibility requirements covering capital levels, profitability and decline in net worth. Fannie Mae requires seller/servicers to be well capitalized for regulatory purposes. For the profitability requirement, we cannot record four or more consecutive quarterly losses and experience a 30% decline in net worth over the same period. Our net worth cannot decline by more than 25% in one quarter or more than 40% over two consecutive quarters.

Loans sold and serviced that have had servicing rights capitalized$3,543,745 $3,541,869 $3,493,312 
Fair value of capitalized mortgage loan servicing rights was determined using an average coupon rate of 4.13%, average servicing fee of 0.26%, average discount rate of 10.37% and an average Public Securities Association (‘‘PSA’’) prepayment rate of 125 for December 31, 2024; and average coupon rate of 3.89%, average servicing fee of 0.26%, average discount rate of 10.25% and an average PSA prepayment rate of 142 for December 31, 2023.
On December 5, 2024 we executed a letter of intent to sell a portion of our mortgage loan servicing rights to a third party. This sale closed on January 31, 2025 with the sale of approximately $935.3 million of mortgage loan servicing rights (26.4% of total servicing portfolio). This sale represents approximately $13.2 million (28.2%) of the total capitalized mortgage loan servicing right asset. While this transaction closed on January 31, 2025, we continued to service these loans under a sub-servicing arrangement through March 3, 2025, at which time servicing was transferred to the buyer. While there remains a customary hold back of final settlement funds of approximately $0.66 million relating to this transaction, we are not aware of any issues that will have a material impact on this final payment. Transaction expenses relating to this sale were approximately $0.5 million and will be expensed during the first quarter of 2025.

At December 31, 2024, the Bank (our reporting unit) had positive equity and elected to perform a qualitative assessment to determine if it was more likely than not that the fair value of the Bank exceeds its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value of the Bank exceeded its carrying value, resulting in no impairment.
Intangible amortization expense was $0.5 million, $0.5 million and $0.8 million during the years ended 2024, 2023 and 2022, respectively.

Average borrowings with the FRB during the years ended December 31, 2024, 2023 and 2022 totaled $0.2 million, $4.5 million and $26.4 million, respectively. We had unused borrowing capacity with the FRB (subject to the FRB’s credit requirements and policies) of $501.8 million at December 31, 2024. Collateral for FRB borrowings are certain securities AFS, securities HTM, commercial loans and installment loans. Interest expense on borrowings with the FRB amounted to $0.01 million, $0.19 million and $0.75 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Advances from the FHLB are secured by unencumbered qualifying mortgage and home equity loans with a market value equal to at least 125% to 165%, respectively, of outstanding advances as well as certain securities AFS, securities HTM and by the FHLB stock that we own. Unused borrowing capacity with the FHLB (subject to the FHLB’s credit requirements and policies) was $1.08 billion at December 31, 2024. Interest expense on advances amounted to $2.0 million, $2.4 million and $0.2 million for the years ended December 31, 2024, 2023 and 2022, respectively. During 2024 we exercised a call option and terminated the $50.0 million fixed rate advance in the table below with no penalty.
As a member of the FHLB, we must own FHLB stock equal to the greater of 0.10% of total assets or 4.5% of our outstanding advances and certain loans sold to the FHLB. At December 31, 2024, we were in compliance with the FHLB stock ownership requirements.

Subordinated Borrowings [Abstract]  
Subordinated Debt and Debentures SUBORDINATED DEBT AND DEBENTURES
Subordinated Debt
In May 2020, we issued $40.0 million of fixed to floating subordinated notes with a ten year maturity (May 31, 2030 maturity date) and a five year call option. The initial coupon rate is 5.95% fixed for five years and then floats at the Secured Overnight Financing Rate (“SOFR”) plus 5.825%. These notes are presented in the Consolidated Statement of Financial Condition under the caption “Subordinated debt” and the balances of $39.59 million and $39.51 million at December 31, 2024 and 2023, respectively are net of remaining unamortized deferred issuance costs of approximately $0.41 million and $0.49 million, respectively that are being amortized through the maturity date into interest expense on other borrowings and subordinated debt and debentures in our Consolidated Statement of Operations. We may redeem the notes, in whole or in part, on or after May 31, 2025, and may redeem the notes at any time in whole upon certain other events. Any redemption of the notes will be subject to prior regulatory approval to the extent required.
Subordinated Debentures
We have formed various special purpose entities (the ‘‘trusts’’) for the purpose of issuing trust preferred securities in either public or pooled offerings or in private placements. Independent Bank Corporation owns all of the common stock of each trust and has issued subordinated debentures to each trust in exchange for all of the proceeds from the issuance of the common stock and the trust preferred securities. Trust preferred securities totaling $38.6 million and $38.5 million at December 31, 2024 and 2023, respectively, qualified as Tier 1 regulatory capital.
These trusts are not consolidated with Independent Bank Corporation and accordingly, we report the common securities of the trusts held by us in accrued income and other assets and the subordinated debentures that we have issued to the trusts in the liability section of our Consolidated Statements of Financial Condition.
As the result of a previous acquisition we acquired TCSB Statutory Trust I as summarized in the tables below at a discount. The discount at acquisition totaled $1.4 million and is being amortized through its maturity date and is included in interest expense – other borrowings and subordinated debt and debentures in the Consolidated Statements of Operations.

The subordinated debentures and trust preferred securities are cumulative and have a feature that permits us to defer distributions (payment of interest) from time to time for a period not to exceed 20 consecutive quarters. Interest is payable quarterly on each of the subordinated debentures and trust preferred securities and no distributions were deferred at December 31, 2024 and 2023.
We have the right to redeem the subordinated debentures and trust preferred securities (at par) in whole or in part from time to time on or after the first permitted redemption date specified above or upon the occurrence of specific events defined within the trust indenture agreements.
Distributions (payment of interest) on the trust preferred securities are included in interest expense – other borrowings and subordinated debt and debentures in the Consolidated Statements of Operations.

Commitments and Contingent Liabilities

Commitments and Contingencies Disclosure [Abstract]  
Commitments and Contingent Liabilities COMMITMENTS AND CONTINGENT LIABILITIES
In the normal course of business, we enter into financial instruments with off-balance sheet risk to meet the financing needs of customers or to reduce exposure to fluctuations in interest rates. These financial instruments may include commitments to extend credit and standby letters of credit. Financial instruments involve varying degrees of credit and interest-rate risk in excess of amounts reflected in the Consolidated Statements of Financial Condition. Exposure to credit risk in the event of non-performance by the counterparties to the financial instruments for loan commitments to extend credit and standby letters of credit is represented by the contractual amounts of those instruments.
A summary of financial instruments with off-balance sheet risk at December 31 follows:
20242023
(In thousands)
Financial instruments whose risk is represented by contract amounts  
Commitments to extend credit$952,299 $881,697 
Standby letters of credit13,026 11,651 
Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and generally require payment of a fee. Since commitments may expire without being drawn upon, the commitment amounts do not represent future cash requirements. Commitments are issued subject to similar underwriting standards, including collateral requirements, as are generally involved in the extension of credit facilities.
Standby letters of credit are written conditional commitments issued to guarantee the performance of a customer to a third party. The credit risk involved in such transactions is essentially the same as that involved in extending loan facilities and, accordingly, standby letters of credit are issued subject to similar underwriting standards, including collateral requirements, as are generally involved in the extension of credit facilities. The majority of the standby letters of credit are on-demand with no stated maturity date and have variable rates that range from 1.00% to 13.50%.
Economic

Pressures from various global and national macroeconomic conditions, including heightened inflation, uncertainty regarding future interest rates, foreign currency exchange rate fluctuations, recent adverse weather conditions, the continuation of the Russia-Ukraine war, ongoing conflict in the Middle East, and potential governmental responses to these events, continue to create significant economic uncertainty. In addition, pursuit of various initiatives announced by the new Trump administration may create some degree of volatility in our customers’ businesses, regulation of the financial services industry, and the markets in which we operate.

The extent to which these pressures and other factors may impact our business, results of operations, asset valuations, financial condition, and customers will depend on future developments, which continue to be highly uncertain and difficult to predict. Material adverse impacts may include all or a combination of valuation impairments on our intangible assets, securities available for sale, securities held to maturity, loans, capitalized mortgage loan servicing rights or deferred tax assets.

We continue to closely monitor and analyze the higher risk segments within our portfolio, and senior management is cautiously optimistic that we are positioned to continue managing the impact of the varied set of risks and uncertainties currently impacting the global and U.S. economies. However, a high degree of uncertainty still exists with respect to the impact of these fluid macroeconomic conditions on the future performance of our loan portfolio and our financial results.
Litigation
We are involved in various litigation matters in the ordinary course of business. At the present time, we do not believe any of these matters will have a significant impact on our consolidated financial position or results of operations. The aggregate amount we have accrued for losses we consider probable as a result of these litigation matters is immaterial. However, because of the inherent uncertainty of outcomes from any litigation matter, we believe it is reasonably possible
we may incur losses in addition to the amounts we have accrued. At this time, we estimate the maximum amount of additional losses that are reasonably possible is insignificant. However, because of a number of factors, including the fact that certain of these litigation matters are still in their early stages, this maximum amount may change in the future.
The litigation matters described in the preceding paragraph primarily include claims that have been brought against us for damages, but do not include litigation matters where we seek to collect amounts owed to us by third parties (such as litigation initiated to collect delinquent loans). These excluded, collection-related matters may involve claims or counterclaims by the opposing party or parties, but we have excluded such matters from the disclosure contained in the preceding paragraph in all cases where we believe the possibility of us paying damages to any opposing party is remote.
Visa Stock
On May 6, 2024, we exchanged 12,566 shares of Visa Inc. Class B-1 common stock (all of the Class B-1 shares we owned) for 2,493 shares of Visa Inc. Class C common stock and 6,283 shares of Visa Inc. Class B-2 common stock pursuant to an exchange offer conducted by Visa. Each Class C share automatically converts to 4 shares of Visa Inc. Class A common stock upon a transfer to anyone other than a Visa member or an affiliate of a Visa member. The Class B-2 shares have the same transfer restrictions as the transfer restrictions on the Class B-1 shares and can only be sold to other Class B shareholders.
Because of the very limited liquidity for the Class B-1 shares (prior to completion of the exchange offer) and uncertainty regarding the likelihood, ultimate timing, and eventual exchange rate for Class B-1 shares into Class A shares, we were carrying these shares at zero, representing cost basis less impairment. In light of the continued uncertainty regarding the likelihood, ultimate timing, and eventual exchange rate for Class B-2 shares into Class A shares, we are carrying the Class B-2 shares at zero, representing cost basis less impairment. However, given the current conversion ratio of 1.543 Class A shares for every 1 Class B-2 share and the closing price of Visa Class A shares on February 24, 2025 of $349.86 per share, our 6,283 Class B-2 shares would have a current “value” of approximately $3.4 million.
With the completion of the exchange, we recorded a gain related to the Class C shares of $2.677 million during the second quarter of 2024 based on the conversion privilege of those shares and the closing price of the Class A shares on May 3, 2024 (the exchange expiration date) of $268.49 per share. Subsequent to the exchange, we sold all 2,493 shares of our Class C shares for net proceeds of $2.685 million. We held no Class C shares at December 31, 2024.
As a condition to our participation in the exchange offer, we were required to enter into a Makewhole Agreement that will require us to reimburse Visa in certain circumstances if certain litigation in which Visa has been involved since 2008 results in damages significantly higher than Visa currently expects. Potential payments under the Makewhole Agreement are designed to equal the decline in value we would have experienced had we not participated in Visa’s exchange offer. Based on the disclosures that have been made by Visa regarding the status of this litigation and other circumstances relating to the exchange offer and potential future, similar exchange offers, we believe the likelihood we will have to make any payments under the Makewhole Agreement is remote.

We assess whether a valuation allowance should be established against our deferred tax assets based on the consideration of all available evidence using a ‘‘more likely than not’’ standard. The ultimate realization of this asset is primarily based on generating future income. We concluded at both December 31, 2024 and 2023, that the realization of substantially all of our deferred tax assets continues to be more likely than not.

Share-Based Payment Arrangement [Abstract]  
Share-Based Compensation and Benefit Plans SHARE BASED COMPENSATION AND BENEFIT PLANS
We maintain share based payment plans that include a non-employee director stock purchase plan and a long-term incentive plan that permits the issuance of share based compensation, including stock options and non-vested share awards. The long-term incentive plan, which is shareholder approved, permits the grant of additional share based awards for up to 0.4 million shares of common stock as of December 31, 2024. The non-employee director stock purchase plan permits the issuance of additional share based payments for up to 0.1 million shares of common stock as of December 31, 2024. Share based awards and payments are measured at fair value at the date of grant and are expensed over the requisite service period. Common shares issued upon exercise of stock options come from currently authorized but unissued shares.
During 2024, 2023 and 2022 pursuant to our long-term incentive plan, we granted 0.09 million, 0.08 million and 0.06 million shares, respectively of restricted stock and 0.02 million during each year of performance stock units (‘‘PSU’’), to certain officers. The shares of restricted stock and PSUs generally cliff vest after a period of three years. The performance criteria of the PSUs is split evenly between a comparison of (i) our total shareholder return and (ii) our return on average assets each over the three year period starting on the grant date to these same criteria over that period to an index of our banking peers.
Our directors may elect to receive all or a portion of their cash retainer fees in the form of common stock (either on a current basis or on a deferred basis) pursuant to the non-employee director stock purchase plan referenced above. Shares equal in value to that portion of each director’s fees that he or she has elected to receive in stock on a current basis are issued each quarter and vest immediately. Shares issued on a deferred basis are credited at the rate of 90% of the current fair value of our common stock and vest immediately. We issued 0.01 million, 0.02 million and 0.02 million shares to directors pursuant to this plan during each of the years ending 2024, 2023 and 2022, respectively and expensed their value during those same periods.
Total compensation expense recognized for grants pursuant to our long-term incentive plan was $2.1 million, $1.9 million and $1.8 million in 2024, 2023 and 2022, respectively. The corresponding tax benefit relating to this expense was $0.4 million, $0.4 million, and $0.4 million during each year, respectively. Total expense recognized for non-employee director share based payments was $0.2 million, $0.4 million, and $0.4 million for the years ending 2024, 2023 and 2022, respectively. The corresponding tax benefit relating to this expense was $0.05 million, $0.08 million and $0.08 million in 2024, 2023 and 2022, respectively.
At December 31, 2024, the total expected compensation cost related to non-vested restricted stock and PSUs not yet recognized was $2.7 million. The weighted-average period over which this amount will be recognized is 1.97 years.

We matched 50% of employee contributions to the 401(k) plan up to a maximum of 8% of participating employees’ eligible wages for 2024, 2023 and 2022. Contributions to the employee stock ownership plan are determined annually and require approval of our Board of Directors. The maximum contribution is 6% of employees’ eligible wages. Contributions to the employee stock ownership plan were 2% for each of 2024, 2023 and 2022. Amounts expensed for these retirement plans were $3.3 million, $3.1 million and $2.9 million in 2024, 2023 and 2022, respectively.
Our employees participate in various performance-based compensation plans. Amounts expensed for all incentive plans totaled $12.9 million, $8.0 million and $12.7 million in 2024, 2023 and 2022, respectively.
We also provide certain health care and life insurance programs to substantially all full-time employees. Amounts expensed for these programs totaled $7.1 million, $7.2 million and $6.2 million in 2024, 2023 and 2022 respectively.
These insurance programs are also available to retired employees at their own expense.

We have established management objectives and strategies that include interest-rate risk parameters for maximum fluctuations in net interest income and market value of portfolio equity. We monitor our interest rate risk position via simulation modeling reports. The goal of our asset/liability management efforts is to maintain profitable financial leverage within established risk parameters.
We have entered into pay-fixed interest rate swaps and caps to protect a portion of the fair value of a certain fixed rate commercial loan and certain mortgage and installment loans (‘‘Fair Value Hedge – Portfolio Loans’’). As a result, changes in the fair values of the pay-fixed interest rate swaps and caps are expected to offset changes in the fair values of the fixed rate portfolio loans due to fluctuations in interest rates. We record the fair values of Fair Value Hedge – Portfolio Loans in accrued income and other assets and accrued expenses and other liabilities on our Condensed Consolidated Statements of Financial Condition. The hedged items (a fixed rate commercial loan and certain fixed rate mortgage and installment loans) are also recorded at fair value which offsets the adjustment to the Fair Value Hedge – Portfolio Loans. On an ongoing basis, we adjust our Condensed Consolidated Statements of Financial Condition to reflect the then current fair values of both the Fair Value Hedge – Portfolio Loans and the hedged items. The related gains or losses are reported in interest income – interest and fees on loans in our Condensed Consolidated Statements of Operations. During the second quarter of 2023 we terminated the interest rate cap that was previously hedging certain installment loans. The remaining unrealized gain on this terminated interest cap is being amortized into earnings over the original life of the interest rate cap.
We have entered into pay-fixed interest rate swaps and interest rate cap agreements to protect a portion of the fair value of certain securities available for sale (‘‘Fair Value Hedge – AFS Securities’’). As a result, the change in the fair value of the pay-fixed interest rate swaps and interest rate cap agreements is expected to offset a portion of the change in the fair value of the fixed rate securities available for sale due to fluctuations in interest rates. We record the fair value of Fair Value Hedge – AFS Securities in accrued income and other assets and accrued expenses and other liabilities on our Consolidated Statements of Financial Condition. The hedged items (fixed rate securities available for sale) are also recorded at fair value which offsets the adjustment to the Fair Value Hedge – AFS Securities. On an ongoing basis, we adjust our Consolidated Statements of Financial Condition to reflect the then current fair value of both the Fair Value Hedge – AFS Securities and the hedged item. The related gains or losses are reported in interest income – interest on securities – tax-exempt in our Consolidated Statements of Operations.
We have entered into interest rate floor agreements to manage the variability in future expected cash flows of certain commercial loans (‘‘Cash Flow Hedge – Portfolio Loans’’). We record the fair value of Cash Flow Hedge – Portfolio Loans in accrued income and other assets and accrued expenses and other liabilities on our Consolidated Statements of Financial Condition. The changes in the fair value of Cash Flow Hedge - Portfolio Loans are recorded in accumulated other comprehensive loss and are reclassified into the line item in our Consolidated Statements of Operations in which the hedged items are recorded in the same period the hedged items affect earnings.
We have entered into interest an rate cap agreement to manage the variability in future expected cash flows of certain short-term funding liabilities (‘‘Cash Flow Hedge – Short-term Funding Liabilities’’). We record the fair value of Cash Flow Hedge – Short-term Funding Liabilities in accrued income and other assets and accrued expenses and other liabilities on our Consolidated Statements of Financial Condition. The changes in the fair value of Cash Flow Hedge - Short-term Funding Liabilities are recorded in accumulated other comprehensive loss and are reclassified into the line item in our Consolidated Statements of Operations in which the hedged items are recorded in the same period the hedged items affect earnings.
For Cash Flow Hedges, it is anticipated that as of December 31, 2024, $1.8 million will be reclassified from accumulated other comprehensive loss on as a reduction to earnings over the next twelve months. The maximum term of any Cash Flow Hedge at December 31, 2024 is 3.7 years.
Certain derivative financial instruments have not been designated as hedges. The fair value of these derivative financial instruments has been recorded on our Consolidated Statements of Financial Condition and is adjusted on an ongoing basis to reflect their then current fair value. The changes in fair value of derivative financial instruments not designated as hedges are recognized in earnings.
In the ordinary course of business, we enter into rate-lock mortgage loan commitments with customers (‘‘Rate-Lock Commitments’’). These commitments expose us to interest rate risk. We also enter into mandatory commitments to sell mortgage loans (‘‘Mandatory Commitments’’) to reduce the impact of price fluctuations of mortgage loans held for sale and Rate-Lock Commitments. Mandatory Commitments help protect our loan sale profit margin from fluctuations in interest rates. The changes in the fair value of Rate Lock Commitments and Mandatory Commitments are recognized currently as part of net gains on mortgage loans in the Consolidated Statements of Operations. We obtain market prices on Mandatory Commitments and Rate-Lock Commitments. Net gains on mortgage loans, as well as net income, may be more volatile as a result of these derivative instruments, which are not designated as hedges.
We have a program that allows commercial loan customers to lock in a fixed rate for a longer period of time than we would normally offer for interest rate risk reasons. We will enter into a variable rate commercial loan and an interest rate swap agreement with a customer and then enter into an offsetting interest rate swap agreement with an unrelated party. The interest rate swap agreement fair values will generally move in opposite directions resulting in little or no net impact on our Consolidated Statements of Operations. All of the interest rate swap agreements-commercial with no hedge designation in the table above relate to this program.
We had entered into a no hedge designation pay-variable interest rate swap agreement in an attempt to manage the cost of certain funding liabilities. The changes in fair value of this no hedge pay-variable interest rate swap is recorded in non-interest expense-other in our Consolidated Statements of Operations. This no hedge designation pay-variable interest rate swap agreement matured during the third quarter of 2023.
We had purchased a swaption agreement during 2021 in an attempt to reduce the impact of price fluctuations of certain mortgage construction loans held for sale. The swaption agreement is presented as "Interest rate swaption agreement" in the table below. The swaption agreement terminated during 2022. The changes in the fair value of the swaption agreement was recognized currently as part of net gains on mortgage loans in our Consolidated Statements of Operations.
In prior years we had entered into certain interest rate cap agreements to manage the variability in future expected cash flows of certain debt obligations. The no hedge designation "Interest rate cap agreements" in the table below had previously qualified for cash flow hedge accounting but were classified to a no hedge designation during 2020 and any changes in fair value since the transfers to the no hedge designation had been recognized in interest expense – other borrowings and subordinated debt and debentures in our Consolidated Statements of Operations since that time. Also in 2020 it became probable that the forecasted transactions being hedged by these interest rate cap agreements would not occur by the end of the originally specified time period and all remaining unrealized losses included as a component of
accumulated other comprehensive income (loss) were reclassified into earnings at that time. In 2022 we terminated $75.0 million of interest rate caps while $15.0 million matured.

Leases [Abstract]  
Leases LEASES
We have entered into leases in the normal course of business primarily for office facilities, some of which include renewal options and escalation clauses. Certain leases also include both lease components (fixed payments including rent, taxes and insurance costs) and non-lease components (common area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components together for all leases. We have also elected not to recognize leases with original lease terms of 12 months or less (short-term leases) on our Consolidated Statements of Financial Condition. Most of our leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion and are included in our right of use (“ROU”) assets and lease liabilities if they are reasonably certain of exercise.
Leases are classified as operating or finance leases at the lease commencement date (we did not have any finance leases as of December 31, 2024). Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease term. The ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of the lease payment over the lease term.
As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments.

Risks and Uncertainties [Abstract]  
Concentrations of Credit Risk CONCENTRATIONS OF CREDIT RISK
Credit risk is the risk to earnings and capital arising from an obligor’s failure to meet the terms of any contract with our organization or otherwise failing to perform as agreed. Credit risk can occur outside of our traditional lending activities and can exist in any activity where success depends on counterparty, issuer or borrower performance. Concentrations of credit risk (whether on- or off-balance sheet) arising from financial instruments can exist in relation to individual borrowers or groups of borrowers, certain types of collateral, certain types of industries or certain geographic regions. Credit risk associated with these concentrations could arise when a significant amount of loans or other financial instruments, related by similar characteristics, are simultaneously impacted by changes in economic or other conditions that cause their probability of repayment or other type of settlement to be adversely affected. Our major concentrations of credit risk arise by collateral type and by industry. The significant concentrations by collateral type at December 31, 2024, include $1.464 billion of loans secured by residential real estate and $322.1 million of construction and land development loans.
Additionally, within our commercial real estate and commercial and industrial loan classes, we had significant standard industry classification concentrations in the following categories as of December 31, 2024: Lessors of Nonresidential Real Estate ($362.6 million); Construction ($186.2 million); Health Care and Social Assistance ($156.8 million); Lessors of Residential Real Estate ($154.5 million); Accommodation and Food Services ($151.0 million); and Manufacturing ($107.0 million). A geographic concentration arises because we primarily conduct our lending activities in the State of Michigan.

Regulatory Matters [Abstract]  
Regulatory Matters REGULATORY MATTERS
Capital guidelines adopted by federal and state regulatory agencies and restrictions imposed by law limit the amount of cash dividends our Bank can pay to us. Under these guidelines, the amount of dividends that may be paid in any calendar year is limited to the Bank’s current year net profits, combined with the retained net profits of the preceding two years. Further, the Bank cannot pay a dividend at any time that it has negative undivided profits. As of December 31, 2024, the
Bank had positive undivided profits of $222.1 million. It is not our intent to have dividends paid in amounts that would reduce the capital of our Bank to levels below those which we consider prudent or that would not be in accordance with guidelines of regulatory authorities.
We are also subject to various regulatory capital requirements. The prompt corrective action regulations establish quantitative measures to ensure capital adequacy and require minimum amounts and ratios of total, Tier 1, and common equity Tier 1 capital to risk-weighted assets and Tier 1 capital to average assets. Failure to meet minimum capital requirements can result in certain mandatory, and possibly discretionary, actions by regulators that could have a material effect on our consolidated financial statements. In addition, capital adequacy rules include a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets that applies to all supervised financial institutions. To avoid limits on capital distributions and certain discretionary bonus payments we must meet the minimum ratio for adequately capitalized institutions plus the buffer. Under capital adequacy guidelines, we must meet specific capital requirements that involve quantitative measures as well as qualitative judgments by the regulators. The most recent regulatory filings as of December 31, 2024 and 2023, have our Bank categorized as well capitalized and exceeding the minimum ratio for adequately capitalized institutions plus the capital conservation buffer. Management is not aware of any conditions or events that would have changed the most recent Federal Deposit Insurance Corporation (‘‘FDIC’’) categorization.

Fair Value Disclosures

Fair Value Disclosures [Abstract]  
Fair Value Disclosures FAIR VALUE DISCLOSURES
FASB ASC topic 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. FASB ASC topic 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.
The standard describes three levels of inputs that may be used to measure fair value:
Level 1: Valuation is based upon quoted prices for identical instruments traded in active markets. Level 1 instruments include securities traded on active exchange markets, such as the New York Stock Exchange, as well as U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets.
Level 2: Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 instruments include securities traded in less active dealer or broker markets.
Level 3: Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.
We used the following methods and significant assumptions to estimate fair value:
Securities: Where quoted market prices are available in an active market, securities are classified as Level 1 of the valuation hierarchy. We currently do not have any Level 1 securities. If quoted market prices are not available for the specific security, then fair values are estimated by (1) using quoted market prices of securities with similar characteristics,
(2) matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities’ relationship to other benchmark quoted prices, or (3) a discounted cash flow analysis whose significant fair value inputs can generally be verified and do not typically involve judgment by management. These securities are classified as Level 2 of the valuation hierarchy and primarily include agency securities, private label mortgage-backed securities, other asset backed securities, obligations of states and political subdivisions, trust preferred securities, corporate securities and foreign government securities.
Loans held for sale: The fair value of mortgage loans held for sale, carried at fair value is based on agency cash window loan pricing for comparable assets (recurring Level 2).
Collateral dependent loans with specific loss allocations based on collateral value: From time to time, certain collateral dependent loans will have an ACL established. When the fair value of the collateral is based on an appraised value or when an appraised value is not available we record the collateral dependent loan as nonrecurring Level 3. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments can be significant and thus will typically result in a Level 3 classification of the inputs for determining fair value.
Other real estate: At the time of acquisition, other real estate is recorded at fair value, less estimated costs to sell, which becomes the property’s new basis. Subsequent write-downs to reflect declines in value since the time of acquisition may occur from time to time and are recorded in net gains on other real estate and repossessed assets, which is part of non-interest expense - other in the Consolidated Statements of Operations. The fair value of the property used at and subsequent to the time of acquisition is typically determined by a third party appraisal of the property. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments can be significant and typically result in a Level 3 classification of the inputs for determining fair value.
Appraisals for both collateral-dependent loans and other real estate are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by us. Once received, an independent third party, or a member of our Collateral Evaluation Department (for commercial properties), or a member of our Special Assets Group (for residential properties) reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. We compare the actual selling price of collateral that has been sold to the most recent appraised value of our properties to determine what additional adjustment, if any, should be made to the appraisal value to arrive at fair value. For commercial and residential properties we typically discount an appraisal to account for various factors that the appraisal excludes in its assumptions. These additional discounts generally do not result in material adjustments to the appraised value.
Capitalized mortgage loan servicing rights: The fair value of capitalized mortgage loan servicing rights is based on a valuation model used by an independent third party that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income. Certain model assumptions are generally unobservable and are based upon the best information available including data relating to our own servicing portfolio, reviews of mortgage servicing assumption and valuation surveys and input from various mortgage servicers and, therefore, are recorded as Level 3. Management evaluates the third party valuation for reasonableness each quarter as part of our financial reporting control processes.
Derivatives: The fair value of rate-lock mortgage loan commitments is based on agency cash window loan pricing for comparable assets and the fair value of mandatory commitments to sell mortgage loans is based on mortgage backed security pricing for comparable assets (recurring Level 2). The fair value of interest rate swap, interest rate cap and interest rate floor agreements are derived from proprietary models which utilize current market data. The significant fair value inputs can generally be observed in the market place and do not typically involve judgment by management (recurring Level 2).

The fair value of our capitalized mortgage loan servicing rights has been determined based on a valuation model used by an independent third party as discussed above. The significant unobservable inputs used in the fair value measurement of the capitalized mortgage loan servicing rights are discount rate, cost to service, ancillary income, float rate and prepayment rate. Significant changes in all five of these assumptions in isolation would result in significant changes to the value of our capitalized mortgage loan servicing rights.

Fair Values Of Financial Instruments [Abstract]  
Fair Values of Financial Instruments FAIR VALUES OF FINANCIAL INSTRUMENTS
Most of our assets and liabilities are considered financial instruments. Many of these financial instruments lack an available trading market and it is our general practice and intent to hold the majority of our financial instruments to maturity. Significant estimates and assumptions were used to determine the fair value of financial instruments. These estimates are subjective in nature, involving uncertainties and matters of judgment, and therefore, fair values may not be a precise estimate. Changes in assumptions could significantly affect the estimates.
Estimated fair values have been determined using available data and methodologies that are considered suitable for each category of financial instrument. For instruments with adjustable interest rates which reprice frequently and without significant credit risk, it is presumed that estimated fair values approximate the recorded book balances.
The estimated recorded book balances and fair values at December 31 follow:

Deposits with no stated maturity include reciprocal deposits with a recorded book balance of $797.224 million and $723.014 million at December 31, 2024 and 2023, respectively. Deposits with a stated maturity include reciprocal deposits with a recorded book balance of $109.807 million and $109.006 million at December 31, 2024 and 2023, respectively.
The fair values for commitments to extend credit and standby letters of credit are estimated to approximate their aggregate book balance, which is nominal, and therefore are not disclosed.
Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale the entire holdings of a particular financial instrument.
Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business, the value of future earnings attributable to off-balance sheet activities and the value of assets and liabilities that are not considered financial instruments.
Fair value estimates for deposit accounts do not include the value of the core deposit intangible asset resulting from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market.

(1)Represents the remaining unrealized loss to be accreted on securities that were transferred from AFS to HTM on April 1, 2022.
The disproportionate tax effects from securities AFS arose primarily due to tax effects of other comprehensive income (‘‘OCI’’) in the presence of a valuation allowance against our deferred tax assets and a pretax loss from operations. Generally, the amount of income tax expense or benefit allocated to operations is determined without regard to the tax effects of other categories of income or loss, such as OCI. However, an exception to the general rule is provided when, in the presence of a valuation allowance against deferred tax assets, there is a pretax loss from operations and pretax income from other categories in the current period. In such instances, income from other categories must offset the current loss from operations, the tax benefit of such offset being reflected in operations. Release of material disproportionate tax effects
from other comprehensive income to earnings is done by the portfolio method whereby the effects will remain in AOCIL as long as we carry a more than inconsequential portfolio of securities AFS.

Revenue from Contract with Customer REVENUE FROM CONTRACTS WITH CUSTOMERS
We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. We derive the majority of our revenue from financial instruments and their related contractual rights and obligations which for the most part are excluded from the scope of this topic. These sources of revenue that are excluded from the scope of this topic include interest income, net gains on mortgage loans, net gains (losses) on securities AFS, mortgage loan servicing, net and bank owned life insurance and were approximately 88.5%, 86.8% and 84.1% of total revenues at December 31, 2024, 2023 and 2022, respectively.
Material sources of revenue that are included in the scope of this topic include service charges on deposit accounts, other deposit related income, interchange income and investment and insurance commissions and are discussed in the following paragraphs. Generally these sources of revenue are earned at the time the service is delivered or over the course of a monthly period and do not result in any contract asset or liability balance at any given period end. As a result, there were no contract assets or liabilities recorded as of December 31, 2024 and 2023.
Service charges on deposit accounts and other deposit related income: Revenues are earned on depository accounts for commercial and retail customers and include fees for transaction-based, account maintenance and overdraft services. Transaction-based fees, which includes services such as ATM use fees, stop payment charges and ACH fees are recognized at the time the transaction is executed as that is the time we fulfill our customer’s request. Account maintenance fees, which includes monthly maintenance services are earned over the course of a month representing the period over which the performance obligation is satisfied. Our obligation for overdraft services is satisfied at the time of the overdraft.
Interchange income: Interchange income primarily includes debit card interchange and network revenues. Debit card interchange and network revenues are earned on debit card transactions conducted through payment networks such as MasterCard and Accel. Interchange income is recognized concurrently with the delivery of services on a daily basis. Interchange and network revenues are presented gross of interchange expenses, which are presented separately as a component of non-interest expense.
Investment and insurance commissions: Investment and insurance commissions include fees and commissions from asset management, custody, recordkeeping, investment advisory and other services provided to our customers. Revenue is recognized on an accrual basis at the time the services are performed and generally based on either the market value of the assets managed or the services provided. We have an agent relationship with a third party provider of these services and net certain direct costs charged by the third party provider associated with providing these services to our customers.
Net (gains) losses on other real estate and repossessed assets: We record a gain or loss from the sale of other real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. If we were to finance the sale of other real estate to the buyer, we would assess whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction is probable. Once these criteria are met, the other real estate asset would be derecognized and the gain or loss on sale would be recorded upon the transfer of control of the property to the buyer. There were no other real estate properties sold during 2024, 2023 or 2022 that were financed by us.

Segment Reporting [Abstract]  
Segment Reporting SEGMENT REPORTING
Independent Bank Corporation is a bank holding company, whose principal activity is the ownership and management of its wholly-owned subsidiaries, including Independent Bank. As a community-oriented financial institution, substantially all of our operations involve the delivery of loan and deposit products to customers.
Our reportable segment is determined by the Chief Executive Officer, who is the designated chief operating decision maker, based upon information provided about the products and services we offer, primarily banking operations. The segment is also distinguished by the level of information provided to the chief operating decision maker, who uses such information to review performance of various components of the business, which are then aggregated if the operating performance, products/services, and customers are similar. The chief operating decision maker will evaluate the performance of our business components such as evaluating revenue streams, significant expenses, and budget to actual results assessing our segment and in the determination of allocating resources. The chief operating decision maker uses revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The chief operating decision maker uses consolidated net income, earnings per share, and return on average assets to benchmark us against our competitors. The benchmarking analysis coupled with monitoring of budget to actual results are used in assessing performance and in establishing compensation. Loans, investments, and deposits provide the majority of revenues in the banking operation. Interest expense, provisions for credit losses, and compensation and employee benefits provide the significant expenses in the banking operation. All operations are domestic.
Accounting policies for our segment are the same as those described in Note #1 - Accounting Policies. Segment performance is evaluated using consolidated net income, earnings per share, and return on average assets. Information reported internally for performance assessment by the chief operating decision maker is as follows, inclusive of reconciliations of significant segment totals to the consolidated financial statements for the years ended December 31, 2024, 2023 and 2022.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Cybersecurity Risk Assessment, Identification, and Management Processes
Our cybersecurity processes have been integrated into our risk management system.
We employ a comprehensive cybersecurity risk assessment program designed to evaluate threats, vulnerabilities, and the potential impact on our operations, data, and financial condition. This program is regularly reviewed and updated to address emerging risks. Our process for addressing risk is based on banking industry best practices outlined in FFIEC and National Institute of Standards and Technology (“NIST”) frameworks.
We engage various third-party service providers in connection with our cybersecurity processes.
We routinely engage consultants and other third parties to assist in the continued improvement and maintenance of our cybersecurity risk assessment program. These engagements are designed to enhance our cybersecurity posture, and we work closely with these experts to help us identify and address risks and vulnerabilities. Examples of these engagements include third party security assessments, security monitoring, and program review.
We closely oversee and monitor third-party cybersecurity service providers.
We maintain policies and procedures to oversee and identify cybersecurity risks associated with our third-party service providers, especially those with access to customer and employee data. Our selection and oversight of these providers incorporate cybersecurity considerations, including contractual and other mechanisms to mitigate risks. Our third-party oversight process follows published frameworks from NIST and FFIEC to account for risks throughout the entire engagement with our third-party vendors.
We consistently engage in proactive measures aimed at preventing, detecting, and effectively minimizing the impact of cybersecurity incidents. We maintain an incident response plan to swiftly respond to breaches, protect customer data, and minimize disruption to our operations. The incident response process is consistently tested and reviewed through simulated incidents and tabletop exercises with key stakeholders. To bolster our incident response process, we have robust business continuity, contingency, and recovery plans to ensure operational resilience during a cybersecurity incident.
We have not experienced a material cybersecurity breach, but risks from cybersecurity threats may impact our business strategy, results of operations, and financial condition.
No risks from any current or previous cybersecurity threats have materially affected or are reasonably likely to materially affect our business strategy, results of operations, or financial condition, except to the extent that such strategy, operations, and conditions are affected by our employment of the cybersecurity risk assessment programs and procedures discussed in this Item. We have not, as of the date of this filing, experienced a cybersecurity breach that has materially affected our business or financial condition. However, because our business involves the collection, transmission, and storage of sensitive customer and employee data, we are susceptible to various cybersecurity threats, including cyberattacks, unauthorized access, and similar events. We employ ongoing processes and strategies to guard against those threats, as discussed in this Item.

Rather than designate one specific board committee to cybersecurity risk management, our entire Board of Directors is responsible for overseeing our risk management.
Cybersecurity Risk Process for Informing Board Committee or Subcommittee Responsible for Oversight [Text Block]
As noted above, our Chief Risk Officer, Chief Information Security Officer, and cybersecurity team provide regular reports to the Board regarding cybersecurity risks, as well as a review of the processes described above. In particular, our Chief Risk Officer provides reports at every regularly scheduled Board meeting regarding our most material risks and the degree of exposure to these risks. Our management personnel are also required to provide more frequent updates to the Enterprise Risk Committee on major developments regarding cybersecurity matters. The Committee, in turn, provides regular updates to the Board on these matters.
Cybersecurity Risk Role of Management [Text Block] Our Chief Risk Officer is responsible for overseeing our risk management
generally, working closely with our internal audit department. Our Chief Risk Officer regularly reports directly to the Board of Directors with respect to all areas of risk management.
With regard to cybersecurity specifically, we have a Chief Information Security Officer who reports to our Chief Information Officer, with a dotted-line reporting relationship to our Chief Executive Officer, and collaborates regularly with our Chief Risk Officer and Risk Team. Our Chief Information Security Officer meets with the Chief Executive Officer on a standard cadence and chairs a committee focused on cybersecurity with monthly reports made to our Risk Committee. Minutes from these meetings as well as select materials are shared with the full Board of Directors, and our Chief Information Security Officer delivers an annual report to our Board of Directors.
In addition, our entire management team is actively engaged in assessing and managing material risks from cybersecurity threats. We have established a robust framework for identifying, preventing, mitigating, and remediating such risks.

Our Chief Information Security Officer holds multiple industry certifications from groups such as ISC2 and GIAC.
To support the Chief Information Security Officer in managing cybersecurity and our Chief Risk Officer in managing cybersecurity risks, we have established a cross-functional cybersecurity team that includes experts in various aspects of information security. This team of employees includes individuals with many years of prior combined work experience in cybersecurity and data protection. These individuals are responsible for the day-to-day implementation of our cybersecurity program, including providing immediate notice to our Chief Information Security Officer and our Chief Risk Officer of any potential cybersecurity incidents.

Accounting Policies (Policies)

Dec. 31, 2024
Accounting Policies [Abstract]  
Principles of Consolidation
PRINCIPLES OF CONSOLIDATION — The consolidated financial statements include the accounts of Independent Bank Corporation and its subsidiaries. The income, expenses, assets and liabilities of the subsidiaries are included in the respective accounts of the consolidated financial statements, after elimination of all intercompany accounts and transactions.
Use of Estimates
USE OF ESTIMATES — To prepare financial statements in conformity with accounting principles generally accepted in the United States of America management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the consolidated financial statements and the disclosures provided, and actual results could differ.
Statements of Cash Flows
STATEMENTS OF CASH FLOWS — For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits and federal funds sold. Generally, federal funds are sold for one-day periods. We report net cash flows for customer loan and deposit transactions and for short-term borrowings.
Interest Bearing Deposits
INTEREST BEARING DEPOSITS — Interest bearing deposits consist of overnight deposits with the Federal Reserve Bank.
Loans Held for Sale LOANS HELD FOR SALE — Mortgage loans originated and intended for sale in the secondary market are carried at fair value. Fair value adjustments, as well as realized gains and losses, are recorded in current earnings.
Operating Segments
OPERATING SEGMENTS — While chief decision-makers monitor the revenue streams of our various products and services, operations are managed and financial performance is evaluated as one single unit. Discrete financial information is not available other than on a consolidated basis for material lines of business.
Capitalized Mortgage Loan Servicing Rights
CAPITALIZED MORTGAGE LOAN SERVICING RIGHTS — We account for our capitalized mortgage loan servicing rights under the fair value method of accounting. We recognize as separate assets the rights to service mortgage loans for others. The fair value of capitalized mortgage loan servicing rights has been determined based upon fair value indications for similar servicing. Under the fair value method we measure capitalized mortgage loan servicing rights at fair value at each reporting date and report changes in fair value of capitalized mortgage loan servicing rights in earnings in the period in which the changes occur and are included in mortgage loan servicing, net in the Consolidated Statements of Operations. The fair value of capitalized mortgage loan servicing rights are subject to significant fluctuations as a result of changes in estimated and actual prepayment speeds and default rates and losses.
Mortgage loan servicing income is recorded for fees earned for servicing loans previously sold. The fees are generally based on a contractual percentage of the outstanding principal and are recorded as income when earned. Mortgage loan servicing fees, excluding fair value changes of capitalized mortgage loan servicing rights, totaled $8.9 million, $8.8 million and $8.6 million for the years ended December 31, 2024, 2023 and 2022, respectively. Late fees and ancillary fees related to loan servicing are not material.
Transfers of Financial Assets
TRANSFERS OF FINANCIAL ASSETS — Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from us, 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 we do not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Securities
SECURITIES — We classify our securities as equity, trading, held to maturity ("HTM") or available for sale ("AFS"). Equity securities are investments in certain equity stocks and are reported at fair value with realized and unrealized gains and losses included in earnings. Trading securities are bought and held principally for the purpose of selling them in the near term and are reported at fair value with realized and unrealized gains and losses included in earnings. Securities HTM represent those securities for which we have the positive intent and ability to hold until maturity and are reported at cost, adjusted for amortization of premiums and accretion of discounts computed on the level-yield method. During 2022 we transferred certain securities AFS with an amortized cost and unrealized loss at the date of transfer of $418.1 million and $26.5 million, respectively to HTM. See note #3 for further discussion of this transfer. We did not have any equity securities or trading securities at December 31, 2024 and 2023. Securities AFS represent those securities not classified as equity, trading or held to maturity and are reported at fair value with unrealized gains and losses, net of applicable income taxes reported in other comprehensive income (loss).
Securities AFS in unrealized loss positions are evaluated quarterly for impairment related to credit losses. For securities AFS in an unrealized loss position, we first assess whether we intend to sell, or it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities AFS that do not meet this criteria, we evaluate whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, we consider the extent to which fair value is less than amortized cost, adverse conditions specifically related to the security and the issuer and the impact of changes in market interest rates on the market value of the security, among other factors. If this assessment indicates that a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses ("ACL") is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income (loss), net of applicable taxes.
The ACL on securities HTM is a contra asset valuation account that is deducted from the carrying amount of securities HTM to present the net amount expected to be collected. Securities HTM are charged off against the ACL when deemed uncollectible. Adjustments to the ACL are reported in our Consolidated Statements of Operations in provision for credit losses. We measure expected credit losses on securities HTM on a collective basis by major security type with each type sharing similar risk characteristics, and we consider historical credit loss information. Accrued interest receivable on securities HTM is excluded from the estimate of credit losses. With regard to U.S. Government-sponsored agency and mortgage-backed securities (residential and commercial), all these securities are issued by a U.S. government-sponsored entity and have an implicit or explicit government guarantee; therefore, no allowance for credit losses has been recorded for these securities. With regard to obligations of states and political subdivisions, private label-mortgage-backed, corporate and trust preferred securities HTM, we consider (1) issuer bond ratings, (2) long-term historical loss rates for given bond ratings, (3) the financial condition of the issuer, and (4) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities.
Gains and losses realized on the sale of securities available for sale are determined using the specific identification method and are recognized on a trade-date basis.
Federal Home Loan Bank ("FHLB") Stock
FEDERAL HOME LOAN BANK (‘‘FHLB’’) STOCK — Our Bank subsidiary is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income in interest income-other investments on the Consolidated Statements of Operations.
Federal Reserve Bank ("FRB") Stock
FEDERAL RESERVE BANK (‘‘FRB’’) STOCK — Our Bank subsidiary is a member of its regional Federal Reserve Bank. FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income in interest income-other investments on the Consolidated Statements of Operations.
Loan Revenue Recognition
LOAN REVENUE RECOGNITION — Interest on loans is accrued based on the principal amounts outstanding. In general, the accrual of interest income is discontinued when a loan becomes 90 days past due for commercial loans and installment loans and when a loan misses four consecutive payments for mortgage loans and the borrower’s capacity to repay the loan and collateral values appear insufficient for each loan class. However, loans may be placed on non-accrual status regardless of whether or not such loans are considered past due if, in management’s opinion, the borrower is unable to meet payment obligations as they become due or as required by regulatory provisions. All interest accrued but not received for all loans placed on non-accrual is reversed from interest income. Payments on such loans are generally applied to the principal balance until qualifying to be returned to accrual status. A non-accrual loan may be restored to accrual status when interest and principal payments are current and the loan appears otherwise collectible. Delinquency status for all classes in the commercial and installment loan portfolio segments is based on the actual number of days past due as required by the contractual terms of the loan agreement while delinquency status for mortgage loan portfolio segment classes is based on the number of payments past due.
Certain loan fees and direct loan origination costs are deferred and recognized as an adjustment of yield generally over the contractual life of the related loan. Fees received in connection with loan commitments are deferred until the loan is advanced and are then recognized generally over the contractual life of the loan as an adjustment of yield. Fees on commitments that expire unused are recognized at expiration. Fees received for letters of credit are recognized as revenue over the life of the commitment.
Allowance for Credit Losses
ALLOWANCE FOR CREDIT LOSSES — Our loan portfolio is disaggregated into segments for purposes of determining the ACL which include commercial, mortgage and installment loans. These segments are further disaggregated into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. Classes within the commercial loan segment include (i) commercial and industrial and (ii) commercial real estate. Classes within the mortgage loan segment include (i) 1-4 family owner occupied - jumbo, (ii) 1-4 family owner occupied - non-jumbo, (iii) 1-4 family non-owner occupied (iv) 1-4 family - 2nd lien and (v) resort lending. Classes within the installment loan segment include (i) boat lending, (ii) recreational vehicle lending, and (iii) other. Commercial loans are subject to adverse market conditions which may impact the borrower’s ability to make repayment on the loan or could cause a decline in the value of the collateral that secures the loan. Mortgage and installment loans are subject to adverse employment conditions in the local economy which could increase default rates. In addition, mortgage loans and real estate based installment loans are subject to adverse market conditions which could cause a decline in the value of collateral that secures the loan. For an analysis of the ACL by portfolio segment and credit quality information by class, see note #4.
We estimate the ACL based on relevant available information from both internal and external sources, including historical loss trends, current conditions and forecasts, specific analysis of individual loans, and other relevant and appropriate factors. The allowance process is designed to provide for expected future losses based on our reasonable and supportable (“R&S”) forecast as of the reporting date. Our ACL process is administered by our Risk Management group utilizing a third party software solution, with significant input and ultimate approval from our Executive Enterprise Risk Committee. Further, we have established a current expected credit loss (“CECL”) Forecast Committee, which includes a cross discipline structure with membership from Executive Management, Risk Management, Credit Administration and Accounting, which approves ACL model assumptions each quarter. Our ACL is comprised of three principal elements: (i) specific analysis of individual loans identified during the review of the loan portfolio, (ii) pooled analysis of loans with similar risk characteristics based on historical experience, adjusted for current conditions, R&S forecasts, and expected prepayments, and (iii) additional allowances based on subjective factors, including local and general economic business factors and trends, portfolio concentrations and changes in the size and/or the general terms of the loan portfolio.
The first ACL element (specific allocations) includes loans that do not share similar risk characteristics and are evaluated on an individual basis. We will typically evaluate on an individual basis loans that are on nonaccrual; commercial loans that have been modified resulting in a concession, for which the borrower is experiencing financial difficulties, and which are considered troubled loan modifications or with well defined weaknesses; and severely delinquent mortgage and installment loans. When we determine that foreclosure is probable or when repayment is expected to be provided substantially through the operation or sale of underlying collateral, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for estimated selling costs. For loans evaluated on an individual basis that are not determined to be collateral dependent, a discounted cash flow analysis is performed to determine expected credit losses.
The second ACL element (pooled analysis) includes loans with similar risk characteristics, which are broken down by segment, class, and risk metric. The Bank’s primary segments of commercial, mortgage, and installment loans are further
classified by other relevant attributes, such as collateral type, lien position, occupancy status, amortization method, and balance size. Commercial classes are additionally segmented by risk rating, and mortgage and installment loan classes by credit score tier, which are updated at least semi-annually.
We utilize a discounted cash flow (“DCF”) model to estimate expected future losses for pooled loans. Expected future cash flows are developed from payment schedules over the contractual term, adjusted for forecasted default (probability of default), loss, and prepayment assumptions. We are not required to develop forecasts over the full contractual term of the financial asset or group of financial assets. Rather, for periods beyond which we are able to make or obtain R&S forecasts of expected credit losses, we revert to the long term average on a straight line or immediate basis, as determined by our CECL Forecast Committee, and which may vary depending on the economic outlook and uncertainty.
The DCF model for the mortgage and installment pooled loan segments includes using probability of default (“PD”) assumptions that are derived through regression analysis with forecasted US unemployment levels by credit score tier. We review a composite forecast of approximately 50 analysts as well as the Federal Open Market Committee (“FOMC”) projections in setting the unemployment forecast for the R&S period. The current ACL utilizes a one year R&S forecast followed by immediate reversion to the 75 year average unemployment rate. PD assumptions for the remaining segments are based primarily on historical rates by risk metric as defaults were not strongly correlated with any economic indicator. Loss given default (“LGD”) assumptions for the mortgage loan segment are based on a two year forecast followed by a two year straight line reversion period to the longer term average, while LGD rates for the remaining segments are the historical average for the entire period. Prepayment assumptions represent average rates per segment for a period determined by the CECL Forecast Committee and as calculated through the Bank’s Asset and Liability Management program.
Pooled reserves for the commercial loan segment are calculated using the DCF model with assumptions generally based on historical averages by class and risk rating. Effective risk rating practices allow for strong predictability of defaults and losses over the portfolio’s expected shorter duration, relative to mortgage and installment loans. Our rating system is similar to those employed by state and federal banking regulators.
The third ACL element (additional allocations based on subjective factors) is based on factors that cannot be associated with a specific credit or loan category and reflects our attempt to ensure that the overall ACL appropriately reflects a margin for the imprecision necessarily inherent in the estimates of expected credit losses. We adjust our quantitative model for certain qualitative factors to reflect the extent to which management expects current conditions and R&S forecasts to differ from the conditions that existed for the period over which historical information was evaluated. The qualitative framework reflects changes related to relevant data, such as changes in asset quality trends, portfolio growth and composition, national and local economic factors, credit policy and administration and other factors not considered in the base quantitative model. We utilize a survey completed by business unit management throughout the Bank, as well as discussion with the CECL Forecast Committee to establish reserves under the qualitative framework.
Increases in the ACL are recorded by a provision for credit losses charged to expense. Although we periodically allocate portions of the ACL to specific loans and loan portfolios, the entire ACL is available for losses.
We generally charge-off commercial, homogenous residential mortgage and installment loans when they are deemed uncollectible or reach a predetermined number of days past due based on loan product, industry practice and other factors. Collection efforts may continue and recoveries may occur after a loan is charged against the ACL.
While we use relevant information to recognize losses on loans, additional provisions for related losses may be necessary based on changes in economic conditions, customer circumstances and other credit risk factors.
Property and Equipment
PROPERTY AND EQUIPMENT — Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the related assets. Buildings are generally depreciated over a period not exceeding 39 years and equipment is generally depreciated over periods not exceeding 7 years. Leasehold improvements are depreciated over the shorter of their estimated useful life or lease period.
Bank Owned Life Insurance
BANK OWNED LIFE INSURANCE — We have purchased a group flexible premium non-participating variable life insurance contract on approximately 253 lives (who were salaried employees at the time we purchased the contract) in order to recover the cost of providing certain employee benefits. Bank owned life insurance is recorded at its cash surrender value or the amount that can be currently realized.
Other Real Estate and Repossessed Assets
OTHER REAL ESTATE AND REPOSSESSED ASSETS — Other real estate at the time of acquisition is recorded at fair value, less estimated costs to sell, which becomes the property’s new basis. Fair value is typically determined by a third party appraisal of the property. Any write-downs at date of acquisition are charged to the ACL. Expense incurred in maintaining other real estate and subsequent write-downs to reflect declines in value and gains or losses on the sale of other real estate are recorded in non-interest expense in the Consolidated Statements of Operations. Non-real estate repossessed assets are treated in a similar manner.
Other Intangibles
OTHER INTANGIBLES — Other intangible assets consist of core deposits. They are initially measured at fair value and then are amortized on both straight-line and accelerated methods over their estimated useful lives, which range from 10 to 15 years.
Goodwill
GOODWILL — Goodwill arises from business combinations and is generally determined as the excess of the fair value of the consideration transferred over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill acquired in a purchase business combination and determined to have an indefinite useful life is not amortized, but tested for impairment at least annually or more frequently if events and circumstances exists that indicate that a goodwill impairment test should be performed. We have selected December 31 as the date to perform the annual impairment test. Goodwill is the only intangible asset with an indefinite life on our Consolidated Statements of Financial Condition.
Income Taxes
INCOME TAXES — We employ the asset and liability method of accounting for income taxes. This method establishes deferred tax assets and liabilities for the temporary differences between the financial reporting basis and the tax basis of our assets and liabilities at tax rates expected to be in effect when such amounts are realized or settled. Under this method, the effect of a change in tax rates is recognized in the period that includes the enactment date. The deferred tax asset is subject to a valuation allowance for that portion of the asset for which it is more likely than not that it will not be realized.
A tax position is recognized as a benefit only if it is ‘‘more likely than not’’ that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination.
We recognize interest and/or penalties related to income tax matters in income tax expense in the Consolidated Statements of Operations.
We file a consolidated federal income tax return. Intercompany tax liabilities are settled as if each subsidiary filed a separate return.
Commitments to Extend Credit and Related Financial Instruments
COMMITMENTS TO EXTEND CREDIT AND RELATED FINANCIAL INSTRUMENTS — Financial instruments may include commitments to extend credit and standby letters of credit. Financial instruments involve varying degrees of credit and interest-rate risk in excess of amounts reflected in the Consolidated Statements of Financial Condition. Exposure to credit risk in the event of non-performance by the counterparties to the financial instruments for loan commitments to extend credit and letters of credit is represented by the contractual amounts of those instruments. In general, we use a similar methodology to estimate our liability for these off-balance sheet credit exposures as we do for our ACL. For commercial related commitments, we estimate liability using our loan rating system and for mortgage and installment commitments we estimate liability principally upon historical loss experience. Our estimated liability for off balance sheet commitments is included in accrued expenses and other liabilities in our Consolidated Statements of Financial Condition and any charge or recovery is recorded in non-interest expense – costs related to unfunded lending commitments in our Consolidated Statements of Operations.
Derivative Financial Instruments
DERIVATIVE FINANCIAL INSTRUMENTS — We record derivatives on our Consolidated Statements of Financial Condition as assets and liabilities measured at their fair value. The accounting for increases and decreases in the value of derivatives depends upon the use of derivatives and whether the derivatives qualify for hedge accounting.
At the inception of the derivative we designate the derivative as one of three types based on our intention and belief as to likely effectiveness as a hedge. These three types are (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (‘‘Fair Value Hedge’’), (2) a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (‘‘Cash Flow Hedge’’), or (3) an instrument with no hedging designation. For a Fair Value Hedge, the gain or loss on the derivative, as well as the offsetting loss or gain on the
hedged item, are recognized in interest income in our Consolidated Statements of Operations. For a Cash Flow Hedge, the gain or loss on the derivative is reported in other comprehensive income (loss) and is reclassified into earnings in the same periods during which the hedged transaction affects earnings. For instruments with no hedging designation, the gain or loss on the derivative is reported in earnings. These free standing instruments primarily consist of (i) mortgage banking related derivatives and include rate-lock loan commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and mandatory forward commitments for the future delivery of these mortgage loans and (ii) certain pay-fixed and pay-variable interest rate swap agreements related to commercial loan customers. The fair value of rate-lock mortgage loan commitments is based on agency cash window loan pricing for comparable assets and the fair value of mandatory commitments to sell mortgage loans is based on mortgage backed security pricing for comparable assets. We enter into mandatory forward commitments for the future delivery of mortgage loans generally when interest rate locks are entered into in order to hedge the change in interest rates resulting from our commitments to fund the loans. Changes in the fair values of these derivatives are included in net gains on mortgage loans in the Consolidated Statements of Operations. Fair values of the pay-fixed and pay-variable interest rate swap agreements are derived from proprietary models which utilize current market data and are included in net interest income in the Consolidated Statements of Operations.
Net cash settlements on derivatives that qualify for hedge accounting are recorded in net interest income in the Consolidated Statements of Operations. Net cash settlements on derivatives that do not qualify for hedge accounting are reported in non-interest income (mortgage banking related derivatives) or net interest income (interest rate swap agreements) in the Consolidated Statements of Operations. Cash flows on hedges are classified in the cash flow statement the same as the cash flows of the items being hedged.
We formally document the relationship between derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions, at the inception of the hedging relationship. This documentation includes linking Fair Value or Cash Flow Hedges to specific assets and liabilities on the Consolidated Statements of Financial Condition or to specific firm commitments or forecasted transactions. We discontinue hedge accounting when it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of the hedged item, the derivative is settled or terminates, a hedged forecasted transaction is no longer probable, a hedged firm commitment is no longer firm, or treatment of the derivative as a hedge is no longer appropriate or intended.
When hedge accounting is discontinued, subsequent changes in fair value of the derivative are recorded in earnings. When a Fair Value Hedge is discontinued, the hedged asset or liability is no longer adjusted for changes in fair value and the existing basis adjustment is amortized or accreted over the remaining life of the asset or liability. When a Cash Flow Hedge is discontinued but the hedged cash flows or forecasted transactions are still expected to occur, gains or losses that were accumulated in other comprehensive income (loss) are amortized into earnings over the same periods which the hedged transactions will affect earnings.
Comprehensive Income (Loss)
COMPREHENSIVE INCOME (LOSS) — Comprehensive income (loss) consists of net income and unrealized gains and losses, net of tax, on securities available for sale and derivative instruments classified as cash flow hedges.
Net Income Per Common Share
NET INCOME PER COMMON SHARE — Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period and participating share awards. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. For diluted net income per common share, net income is divided by the weighted average number of common shares outstanding during the period plus the assumed exercise of stock options, performance share units and stock units for a deferred compensation plan for non-employee directors.
Share-based Compensation
SHARE BASED COMPENSATION — Cost is recognized for non-vested share awards issued to employees based on the fair value of these awards at the date of grant. A simulation analysis which considers potential outcomes for a large number of independent scenarios is utilized to estimate the fair value of performance share units and the market price of our common stock at the date of grant is used for other non-vested share awards. Cost is recognized over the required service period, generally defined as the vesting period. Forfeitures are recognized as they occur. Cost is also recognized for stock issued to non-employee directors. These shares vest immediately and cost is recognized during the period they are issued.
Common Stock
COMMON STOCK — At December 31, 2024, 0.1 million shares of common stock were reserved for issuance under the dividend reinvestment plan, 0.4 million shares of common stock were reserved for issuance under our long-term
incentive plan and 0.1 million shares of common stock were reserved for issuance under our non-employee director stock purchase plan.
Reclassification
RECLASSIFICATION — Certain amounts in the 2023 and 2022 consolidated financial statements have been reclassified to conform to the 2024 presentation.
Adoption of New Accounting Standards
ADOPTION OF NEW ACCOUNTING STANDARDS — In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-04, ‘‘Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting’’ and in December 2022 the FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848), Deferral of the Sunset Date of Topic 848". These new ASUs provide temporary optional expedients and exceptions to GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. Entities can elect not to apply certain modification accounting requirements to contracts affected by reference rate reform, if certain criteria are met. Entities that make such elections would not have to remeasure contracts at the modification date or reassess a previous accounting determination. Entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met.
We had formed a cross-functional project team to lead the transition from LIBOR to a planned adoption of reference rates which included Secured Overnight Financing Rate (“SOFR”). We utilized the timeline guidance published by the Alternative Reference Rates Committee to develop and achieve internal milestones during the transitional period. We discontinued the use of new LIBOR-based loans as of December 31, 2021, according to regulatory guidelines. We also discontinued the use of new LIBOR based interest rate derivatives as of December 31, 2021. The amended guidance under Topic 848 and our ability to elect its temporary optional expedients and exceptions were effective for us through December 31, 2024.
In March, 2023, the FASB issued ASU 2023-02, "Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Issues Task Force)". This ASU expands the use of the proportional amortization method of accounting — currently allowed only for investments in low-income housing tax credit ("LIHTC") structures — to equity investments in other tax credit structures that meet certain criteria. Common tax credit programs that investors access via tax equity structures and that may now be eligible for application of the proportional amortization method include: new markets tax credits, historic rehabilitation tax credit programs, and renewable energy tax credit programs. This ASU takes effect in reporting periods beginning after December 15, 2023, with early adoption permitted. The adoption of this ASU on January 1, 2024, did not have a material impact on our Consolidated Financial Statements.
In November, 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures". This ASU enhances disclosures of significant segment expenses by requiring entities to disclose significant segment expenses regularly provided to the chief operating decision maker, extend certain annual disclosures to interim periods, and permit more than one measure of segment profit or loss to be reported under certain conditions. This ASU takes effect in reporting periods beginning after December 15, 2023, with early adoption permitted. The adoption of this ASU on January 1, 2024, did not have a material impact on the Consolidated Financial Statements.
In December, 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures". This ASU modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). This ASU also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. This ASU takes effect in reporting periods beginning after December 15, 2024, with early adoption permitted. We do not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements.
In December, 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses". This ASU requires public business entities to disaggregate certain expense captions into specific categories in disclosures within the footnotes to the financial statements. This ASU takes effect in annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We do not expect the adoption of this ASU to have a material impact on our Consolidated Financial Statements.

Quantitative Information About Level 3 Fair Value Measurements Measured on a Recurring Basis and Non-recurring Basis
The fair value of our capitalized mortgage loan servicing rights has been determined based on a valuation model used by an independent third party as discussed above. The significant unobservable inputs used in the fair value measurement of the capitalized mortgage loan servicing rights are discount rate, cost to service, ancillary income, float rate and prepayment rate. Significant changes in all five of these assumptions in isolation would result in significant changes to the value of our capitalized mortgage loan servicing rights.

In addition to the valuation techniques and unobservable inputs discussed above, at December 31, 2024 and 2023 certain collateral dependent installment loans totaling approximately $0.29 million and $0.45 million are secured by collateral other than real estate. For the majority of these loans, we apply internal discount rates to industry valuation guides.
