Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include ChoiceOne Financial Services, Inc. ("ChoiceOne"), its wholly-owned subsidiary, ChoiceOne Bank, and ChoiceOne Bank’s wholly-owned subsidiary, ChoiceOne Insurance Agencies, Inc. Intercompany transactions and balances have been eliminated in consolidation. ChoiceOne owns all of the common securities of Community Shores Capital Trust I (the “Capital Trust”). Under U.S. generally accepted accounting principles ("GAAP"), the Capital Trust is not consolidated because it is a variable interest entity and ChoiceOne is not the primary beneficiary. The accompanying unaudited consolidated financial statements and notes thereto reflect all adjustments ordinary in nature which are, in the opinion of management, necessary for a fair presentation of such financial statements. Operating results for the three months ended March 31, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in ChoiceOne’s Annual Report on Form 10-K for the year ended December 31, 2022.
Use of Estimates | Use of Estimates To prepare financial statements in conformity with accounting principles generally accepted in the United States of America, ChoiceOne’s management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided. These estimates and assumptions are subject to many risks and uncertainties, and actual results may differ from these estimates. Estimates associated with the allowance for credit losses and the unrealized gains and losses on securities available for sale and held to maturity are particularly susceptible to change.
Investment Securities | Investment Securities Investment securities for which ChoiceOne has the intent and ability to hold to maturity are classified as held to maturity and are carried at amortized cost. Investment securities not classified as held to maturity are classified as available for sale and are reported at fair value with unrealized gains and losses, net of income taxes, as a separate component of other comprehensive income. ChoiceOne determines the appropriate classification of investment securities at the time of purchase and reassesses the classification at each reporting date. Additions to securities held to maturity consist mostly of local issue municipals.
Goodwill | Goodwill Goodwill results from business acquisitions and represents the excess of the purchase price over the fair value of the acquired tangible assets and liabilities and identifiable intangible assets. Goodwill and intangible assets acquired in a purchase or business combination and determined to have an indefinite useful life are not amortized but tested for impairment at least annually or more frequently if events and circumstances exist that indicate that a goodwill impairment test should be performed.
Core Deposit Intangible | Core Deposit Intangible Core deposit intangible represents the value of the acquired customer core deposit bases and is included as an asset on the consolidated balance sheets. The core deposit intangible has an estimated finite life, is amortized on an accelerated basis over a 120 month period and is subject to periodic impairment evaluation.
Stock Transactions | Stock Transactions A total of 3,220 shares of common stock were issued to ChoiceOne’s Board of Directors for a cash price of $94,000 under the terms of the Directors’ Stock Purchase Plan in the first quarter of 2023. A total of 2,431 shares for a cash price of $53,000 were issued under the Employee Stock Purchase Plan in the first quarter of 2023. ChoiceOne's common stock repurchase program announced in April 2021 and amended in 2022, authorizes repurchases of up to 375,388 shares, representing 5% of the total outstanding shares of common stock as of the date the program was adopted. No shares were repurchased under this program in the first quarter of 2023.
Reclassifications | Reclassifications Certain amounts presented in prior periods have been reclassified to conform to the current presentation.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements Allowance for Credit Losses ("ACL") In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This ASU (as subsequently amended by ASU 2018-19) significantly changed how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard replaced the current “incurred loss” approach with an “expected loss” model. The new model, referred to as the CECL model, applies to financial assets subject to credit losses and measured at amortized cost, and certain off-balance sheet credit exposures. The standard also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the ACL. In addition, entities need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. A reasonable and supportable economic forecast is a key component of the CECL methodology. ChoiceOne adopted CECL effective January 1, 2023 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for reporting periods beginning after January 1, 2023 are presented under CECL while prior period amounts continue to be reported in accordance with the incurred loss accounting standards. The transition adjustment of the CECL adoption included an increase in the ACL of $7.2 million, which included a $5.5 million decrease to the retained earnings account to reflect the cumulative effect of adopting CECL on our Consolidated Balance Sheet, with the $1.5 million tax impact portion being recorded as part of the deferred tax asset in other assets on our Consolidated Balance Sheet. The transition adjustment of the CECL adoption included an additional ACL on unfunded commitments of $3.3 million, which included a $2.6 million decrease to the retained earnings account to reflect the cumulative effect of adopting CECL on our Consolidated Balance Sheet, with the $688,000 tax impact portion being recorded as part of the deferred tax asset in other assets on our Consolidated Balance Sheet. The ACL is a valuation allowance for probable incurred credit losses. The ACL is increased by the provision for credit losses and decreased by loans charged off less any recoveries of charged off loans. As ChoiceOne has had very limited loss experience since 2011, management elected to utilize benchmark peer loss history data to estimate historical loss rates. ChoiceOne worked with a third party advisory firm to identify an appropriate peer group for each loan group which shared similar characteristics. Management estimates the ACL required based on a selected peer group loan loss experience, the nature and volume of the loan portfolio, information about specific borrower situations and estimated collateral values, a reasonable and supportable economic forecast, and other factors. Allocations of the ACL may be made for specific loans, but the entire ACL is available for any loan that, in management’s judgment, should be charged off. Loan losses are charged against the ACL when management believes that collection of a loan balance is not possible. The ACL consists of general and specific components. The general component covers loans collectively evaluated for credit losses and is based on peer historical loss experience adjusted for current and forecasted factors. Management's adjustment for current and forecasted factors is based on trends in delinquencies, trends in charge-offs and recoveries, trends in the volume of loans, changes in underwriting standards, trends in loan review findings, the experience and ability of lending staff, and a reasonable and supportable economic forecast described further below. The discounted cash flow methodology is utilized for all loan pools. This methodology is supported by our CECL software provider and allows management to automatically calculate contractual life by factoring in all cash flows and adjusting them for behavioral and credit-related aspects. Reasonable and supportable economic forecasts have to be incorporated in determining expected credit losses. The forecast period represents the time frame from the current period end through the point in time that we can reasonably forecast and support entity and environmental factors that are expected to impact the performance of our loan portfolio. Ideally, the economic forecast period would encompass the contractual terms of all loans; however, the ability to produce a forecast that is considered reasonable and supportable becomes more difficult or may not be possible in later periods. Subsequent to the end of the forecast period, we revert to historical loan data based on an ongoing evaluation of each economic forecast in relation to then current economic conditions as well as any developing loan loss activity and resulting historical data. As of March 31, 2023, we used a one-year reasonable and supportable economic forecast period, with a two year straight-line reversion period. We are not required to develop and use our own economic forecast model, and elected to utilize economic forecasts from third-party providers that analyze and develop forecasts of the economy for the entire United States at least quarterly. We are also required to consider expected credit losses associated with loan commitments over the contractual period in which we are exposed to credit risk on the underlying commitments unless the obligation is unconditionally cancellable by us. Any allowance for off-balance sheet credit exposures is reported as an other liability on our Consolidated Balance Sheet and is increased or decreased via the provision for credit losses account on our Consolidated Statement of Income. The calculation includes consideration of the likelihood that funding will occur and forecasted credit losses on commitments expected to be funded over their estimated lives. The allowance is calculated using the same aggregate reserve rates calculated for the funded portion of loans at the portfolio level applied to the amount of commitments expected to be funded. . Securities Available for Sale - For securities AFS in an unrealized loss position, management determines whether they intend to sell or if it is more likely than not that ChoiceOne will be required to sell the security before recovery of the 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 with an allowance being established under CECL. For securities AFS with unrealized losses not meeting these criteria, management evaluates whether any decline in fair value is due to credit loss factors. In making this assessment, management considers any changes to the rating of the security by rating agencies and adverse conditions specifically related to the issuer of the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses (“ACL”) is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Changes in the ACL under ASC 326-30 are recorded as provisions for (or reversal of) credit loss expense. Losses are charged against the allowance when the collectability of a debt security AFS is confirmed or when either of the criteria regarding intent or requirement to sell is met. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income, net of income taxes. At March 31, 2023 and at adoption of CECL on January 1, 2023, there was no ACL related to debt securities AFS. Accrued interest receivable on debt securities was excluded from the estimate of credit losses. Loans that do not share risk characteristics are evaluated on an individual basis and are excluded from the collective evaluation. ChoiceOne has determined that any loans which have been placed on non-performing status, loans with a risk rating of 6 or higher, and loans past due more than 60 days will be assessed for individually evaluation. Management's judgment will be used to determine if the loan should be migrated back to pool on an individual basis. Individual analysis will establish a specific reserve for loans in scope. Specific reserves on non-performing loans are typically based on management’s best estimate of the fair value of collateral securing these loans, adjusted for selling costs as appropriate. Securities Held to Maturity - Since the adoption of CECL, ChoiceOne measures credit losses on HTM securities on a collective basis by major security type with each type sharing similar risk characteristics, and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The ACL on securities HTM is a contra asset valuation account that is deducted from the carrying amount of HTM securities to present the net amount expected to be collected. HTM securities are charged off against the ACL when deemed uncollectible. Adjustments to the ACL are reported in ChoiceOne’s Consolidated Statements of Income in the provision for credit losses. Accrued interest receivable on HTM securities is excluded from the estimate of credit losses. With regard to US Treasury securities, these have an explicit government guarantee; therefore, no ACL is recorded for these securities. With regard to obligations of states and political subdivisions and other HTM securities, management considers (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. At March 31, 2023 and at adoption of CECL on January 1, 2023, there was no ACL related to securities HTM. Troubled Loan Modifications FASB also issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. This standard eliminated the previous accounting guidance for troubled debt restructurings and added additional disclosure requirements for gross chargeoffs by year of origination. It also prescribes guidance for reporting modifications of loans to borrowers experiencing financial difficulty. Investment in Equity Method and Joint Ventures In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Venture (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. The amendments in this ASU permit reporting entities to account for the tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method. This update will be effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2023. Early adoption is permitted. ChoiceOne is currently evaluating the impact of this standard on the consolidated financial statements.
Allowance for Credit Losses ("ACL") | Allowance for Credit Losses ("ACL") In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments.

ChoiceOne adopted CECL effective January 1, 2023 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for reporting periods beginning after January 1, 2023 are presented under CECL while prior period amounts continue to be reported in accordance with the incurred loss accounting standards.
