Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements of Union Bankshares, Inc. and Subsidiary (together, the Company) as of June 30, 2023, and for the three and six months ended June 30, 2023 and 2022, have been prepared in conformity with GAAP for interim financial information, general practices within the banking industry, and the accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (2022 Annual Report), except as disclosed in the Summary of Significant Accounting Policies below. The Company's sole subsidiary is Union Bank. In the opinion of the Company’s management, all adjustments, consisting only of normal recurring adjustments and disclosures necessary for a fair presentation of the information contained herein, have been made. This information should be read in conjunction with the Company’s 2022 Annual Report. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2023, or any future interim period. The Company is a “smaller reporting company” and as permitted under the rules and regulations of the SEC, has elected to provide its consolidated statements of income, comprehensive income, cash flows and changes in stockholders’ equity for a two year, rather than three year, period. The Company has also elected to provide certain other scaled disclosures in this report, as permitted for smaller reporting companies. Certain amounts in the 2022 consolidated financial statements have been reclassified to conform to the current year presentation.
Summary Of Significant Accounting Policies and Recent Accounting Pronouncements	Summary of Significant Accounting Policies The disclosures below supplement and update the accounting policies previously disclosed in Note 1. Significant Accounting Policies in the Company’s 2022 Annual Report. The updates reflect the adoption of the FASB ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, more commonly referred to as Current Expected Credit Losses (CECL), effective January 1, 2023. The Company adopted CECL 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 methodology under previously applicable GAAP. Allowance for Credit Losses on AFS Debt Securities: Upon adoption of CECL, effective January 1, 2023, for AFS debt securities in an unrealized loss position, management first assesses whether it intends to sell, or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through earnings. For AFS debt securities that do not meet the above criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security and the issuer, among other factors. If this assessment indicates that a credit loss exists, management compares 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. A change in the ACL on AFS debt securities is recorded as expense (credit) within the Credit loss expense on the consolidated statement of income. Losses are charged against the ACL when management believes the uncollectibility of an AFS debt security is confirmed based on the above described analysis. As of June 30, 2023 and CECL adoption date of January 1, 2023, there was no ACL carried on the Company's AFS debt securities. Refer to Note 5 of the consolidated financial statements for further discussion. Allowance for Credit Losses on Loans: The ACL on loans is a significant accounting estimate used in the preparation of the Company's consolidated financial statements. The level of the ACL on loans represents management's estimate of expected credit losses over the expected life of the loans at the balance sheet date. The expected life of the loans is based on the contractual term of the loans adjusted for estimated prepayments. The contractual life is calculated based on the maturity date and excludes expected extensions, renewals, and modifications. Upon adoption of CECL on January 1, 2023, the Company replaced the incurred loss model that recognizes losses when it becomes probable that a credit loss will be incurred, with a requirement to recognize lifetime expected credit losses based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. The ACL on loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the ACL on loans when they are deemed uncollectible. The ACL on loans is comprised of reserves measured on a collective (pool) basis based on a lifetime loss-rate model when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated on an individual basis, generally larger non-accruing commercial loans. The Company uses the DCF method to estimate expected credit losses for all loan pools. For each of the loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical benchmark data. The Company uses regression analysis of historical internal and peer data to determine suitable loss drivers to utilize when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the loss drivers. For all loan pools utilizing the DCF method, management utilizes and forecasts national unemployment as a loss driver. For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over four quarters on a straight-line basis. Management leverages economic projections from a reputable and independent third party to inform its loss driver forecasts over the four-quarter forecast period. The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level that represents the sum of expected losses to determine the estimated ACL on loans. The ACL on loans evaluation also considers various qualitative factors, including changes in policy and/or underwriting standards, actual or expected changes in economic trends and conditions, changes in the nature and volume of the portfolio, changes in credit and lending staff/administration, problem loan trends, credit risk concentrations, loan review results, changes in the value of underlying collateral for loans, and changes in the regulatory and business environment. Certain loans are individually evaluated for estimated credit losses, including those greater than $500,000 that are classified as substandard or doubtful and are on nonaccrual or that have other unique characteristics differing from the segment. Specific reserves are established when appropriate for such loans based on the present value of expected future cash flows of the loan or the estimated realizable value of the collateral, if any. Management may also adjust its assumptions to account for differences between expected and actual losses from period-to-period. The variability of management's assumptions could alter the ACL on loans materially and impact future results of operations and financial condition. The loss estimation models and methods used to determine the ACL are continually refined and enhanced. Allowance for Credit Losses on Off-Balance Sheet Credit Exposures: The ACL on off-balance sheet credit exposures is a component of Accrued interest and other liabilities on the Company's consolidated balance sheets and represents the estimate of probable credit losses inherent in unfunded commitments to extend credit as of the balance sheet date. Unfunded commitments to extend credit include unused portions of lines of credit, commitments to originate loans and standby and commercial letters of credit. The process used to determine the ACL for these exposures is consistent with the process for determining the ACL on loans, as adjusted for estimated funding probabilities or loan equivalency factors. A charge or credit to Credit loss expense on the consolidated statements of income is made to account for the change in the ACL on off-balance sheet exposures between reporting periods. Accrued Interest: Upon adoption of CECL on January 1, 2023, the Company elected to present accrued interest receivable balances in Other assets on the consolidated balance sheets and exclude accrued interest from the ACL on loans and AFS debt securities. The Company will continue to write-off accrued interest receivable by reversing interest income when a security or loan is placed in nonaccrual, which is generally when payments on a security or loan are 90 days or more past due. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The guidance in the ASU requires that expected credit losses for financial assets held at the reporting date that are accounted for at amortized cost be measured and recognized based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. A modified version of these requirements also applies to debt securities classified as AFS. The ASU became effective for the Company beginning with the 2023 fiscal year. The impact of the ASU on the Company's consolidated financial statements is discussed in Note 1, Summary of Significant Accounting Policies. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and has issued subsequent amendments thereto, which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2024. The transition away from LIBOR is not expected to have a material impact on the Company's consolidated financial statements. In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings (TDRs) and Vintage Disclosures. The guidance amends ASC 326 to eliminate the accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancing and restructuring activities by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying TDR recognition and measurement guidance, creditors will determine whether a modification results in a new loan or continuation of an existing loan. These amendments are also intended to enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, the amendments to ASC 326 require that an entity disclose current-period gross write-offs by year of origination within the vintage disclosures, which requires that an entity disclose the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination. The guidance is only for entities that have adopted the amendments in ASU No. 2016-13 for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted ASU No. 2022-02 effective January 1, 2023. The adoption of the provisions contained within ASU No. 2022-02 did not have a material impact on the consolidated financial statements. In March 2023, the FASB issued ASU No. 2023-02, Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU No. 2014-01, Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects, previously introduced the option to apply the proportional amortization method to account for investments made primarily for the purpose of receiving income tax credits and other income tax benefits when certain requirements are met; however, this guidance limited the proportional amortization method to investments in low-income-housing tax credit (LIHTC) structures. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense (benefit). Equity investments in other tax credit structures are typically accounted for using the equity method, which results in investment income, gains and losses, and tax credits being presented gross on the income statement in their respective line items. The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The amendments in this update are effective for the Company for fiscal years beginning after December 31, 2023, including interim periods within those fiscal years. Early adoption is permitted in any interim period. If early adoption is elected, adoption must be as of the beginning of the fiscal year that includes the interim period of adoption. The amendments in this update must be applied on either a modified retrospective or a retrospective basis. The Company has not elected early adoption and is currently evaluating the impact of this standard for its tax equity investments and the impact to noninterest income, noninterest expense, and income tax expense within the consolidated financial statements.
Loans	Loans Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their unpaid principal balances, adjusted for any charge-offs, the ACL, and any deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Loan interest income is accrued daily on outstanding balances. The following accounting policies, related to accrual and nonaccrual loans, apply to all portfolio segments and loan classes, which the Company considers to be the same. The accrual of interest is normally discontinued when a loan is specifically determined to be impaired and/or management believes, after considering collection efforts and other factors, that the borrower's financial condition is such that collection of interest is doubtful. In general, loans that are 90 days or more past due are placed in nonaccrual, unless there are circumstances that cause management to believe the collection of interest is not doubtful. Generally, any unpaid interest previously accrued on those loans is reversed against current period interest income. A loan may be restored to accrual status when its financial status has significantly improved and there is no principal or interest past due. A loan may also be restored to accrual status if the borrower makes six consecutive monthly payments or the lump sum equivalent. Income on nonaccrual loans is generally not recognized unless a loan is returned to accrual status or after all principal has been collected. Interest payments received on such loans are generally applied as a reduction of the loan principal balance. Delinquency status is determined based on contractual terms for all portfolio segments and loan classes. Loans past due 30 days or more are considered delinquent. Loans are considered in process of foreclosure when a judgment of foreclosure has been issued by the court. Loan origination fees and direct loan origination costs are deferred and amortized as an adjustment of the related loan's yield using methods that approximate the interest method. The Company generally amortizes these amounts over the estimated average life of the related loans.
Allowance for Credit Losses on Loans and Off-Balance Sheet Credit Exposures	Allowance for Credit Losses on Loans 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 under the incurred loss model in accordance with previously applicable GAAP as described in the 2022 Annual Report. The level of the ACL on loans represents management's estimate of expected credit losses over the expected life of the loans at the balance sheet date. For all loan classes, loan losses are charged against the ACL on loans when management believes the loan balance is uncollectible or in accordance with federal guidelines. Subsequent recoveries, if any, are credited to the ACL on loans. Upon adoption of CECL on January 1, 2023, the Company replaced the incurred loss model that recognizes losses when it becomes probable that a credit loss will be incurred, with a requirement to recognize lifetime expected credit losses based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. The ACL on loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. The ACL on loans is comprised of reserves measured on a collective (pool) basis based on a lifetime loss-rate model when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated on an individual basis, generally larger non-accruing commercial loans. Risk characteristics relevant to each portfolio segment are as follows: •Residential real estate - Loans in this segment are collateralized by owner-occupied 1-4 family residential real estate, second and vacation homes, 1-4 family investment properties, home equity and second mortgage loans. Repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, could have an effect on the credit quality of this segment. •Construction real estate - Loans in this segment include residential and commercial construction properties, commercial real estate development loans (while in the construction phase of the projects), land and land development loans. Repayment is dependent on the credit quality of the individual borrower and/or the underlying cash flows generated by the properties being constructed. The overall health of the economy, including unemployment rates, housing prices, vacancy rates and material costs, could have an effect on the credit quality of this segment. •Commercial real estate - Loans in this segment are primarily properties occupied by businesses or income-producing properties. The underlying cash flows generated by the properties may be adversely impacted by a downturn in the economy as evidenced by a general slowdown in business or increased vacancy rates which, in turn, could have an effect on the credit quality of this segment. Management requests business financial statements at least annually and monitors the cash flows of these loans. •Commercial - Loans in this segment are made to businesses and are generally secured by non-real estate assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer or business spending, could have an effect on the credit quality of this segment. •Consumer - Loans in this segment are made to individuals for personal expenditures, such as an automobile purchase, and include unsecured loans. Repayment is primarily dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment, could have an effect on the credit quality of this segment. •Municipal - Loans in this segment are made to municipalities located within the Company's service area. Repayment is primarily dependent on taxes or other funds collected by the municipalities. Management considers there to be minimal risk surrounding the credit quality of this segment.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss)Accounting principles generally require recognized revenue, expenses, gains and losses be included in net income or loss. Certain changes in assets and liabilities, such as the after tax effect of unrealized gains and losses on investment securities AFS that have not been recorded through an ACL are not reflected in the consolidated statements of income. The cumulative effect of such items, net of tax effect, is reported as a separate component of the equity section of the consolidated balance sheets (Accumulated OCI). OCI, along with net income, comprises the Company's total comprehensive income or loss.
Fair Value Measurement	Fair Value Measurement The Company utilizes FASB ASC Topic 820, Fair Value Measurement, as guidance for accounting for assets and liabilities carried at fair value. This standard defines fair value as the price that would be received, without adjustment for transaction costs, to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The guidance in FASB ASC Topic 820 establishes a three-level fair value hierarchy, which prioritizes the inputs used in measuring fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy are: •Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; •Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; •Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
Fair Value Measurement	The following is a description of the valuation methodologies used for the Company’s assets that are measured on a recurring basis at estimated fair value: Investment securities AFS: Certain U.S. Treasury notes have been valued using unadjusted quoted prices from active markets and therefore have been classified as Level 1. However, the majority of the Company’s AFS securities have been valued utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include market maker bids, quotes and pricing models. Inputs to the pricing models include recent trades, benchmark interest rates, spreads and actual and projected cash flows. Mutual funds: Mutual funds have been valued using unadjusted quoted prices from active markets and therefore have been classified as Level 1.

Summary Of Significant Accounting Policies and Recent Accounting Pronouncements

Summary of Significant Accounting Policies

The disclosures below supplement and update the accounting policies previously disclosed in Note 1. Significant Accounting Policies in the Company’s 2022 Annual Report. The updates reflect the adoption of the FASB ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, more commonly referred to as Current Expected Credit Losses (CECL), effective January 1, 2023.

The Company adopted CECL 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 methodology under previously applicable GAAP.

Allowance for Credit Losses on AFS Debt Securities: Upon adoption of CECL, effective January 1, 2023, for AFS debt securities in an unrealized loss position, management first assesses whether it intends to sell, or if it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through earnings. For AFS debt securities that do not meet the above criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security and the issuer, among other factors. If this assessment indicates that a credit loss exists, management compares 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.

A change in the ACL on AFS debt securities is recorded as expense (credit) within the Credit loss expense on the consolidated statement of income. Losses are charged against the ACL when management believes the uncollectibility of an AFS debt security is confirmed based on the above described analysis. As of June 30, 2023 and CECL adoption date of January 1, 2023, there was no ACL carried on the Company's AFS debt securities. Refer to Note 5 of the consolidated financial statements for further discussion.

Allowance for Credit Losses on Loans: The ACL on loans is a significant accounting estimate used in the preparation of the Company's consolidated financial statements. The level of the ACL on loans represents management's estimate of expected credit losses over the expected life of the loans at the balance sheet date. The expected life of the loans is based on the contractual term of the loans adjusted for estimated prepayments. The contractual life is calculated based on the maturity date and excludes expected extensions, renewals, and modifications.

Upon adoption of CECL on January 1, 2023, the Company replaced the incurred loss model that recognizes losses when it becomes probable that a credit loss will be incurred, with a requirement to recognize lifetime expected credit losses based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. The ACL on loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the ACL on loans when they are deemed uncollectible. The ACL on loans is comprised of reserves measured on a collective (pool) basis based on a lifetime loss-rate model when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated on an individual basis, generally larger non-accruing commercial loans.

The Company uses the DCF method to estimate expected credit losses for all loan pools. For each of the loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical benchmark data.

The Company uses regression analysis of historical internal and peer data to determine suitable loss drivers to utilize when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the loss drivers. For all loan pools utilizing the DCF method, management utilizes and forecasts national unemployment as a loss driver.

For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over four quarters on a straight-line basis. Management leverages economic projections from a reputable and independent third party to inform its loss driver forecasts over the four-quarter forecast period.

The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level that represents the sum of expected losses to determine the estimated ACL on loans.

The ACL on loans evaluation also considers various qualitative factors, including changes in policy and/or underwriting standards, actual or expected changes in economic trends and conditions, changes in the nature and volume of the portfolio, changes in credit and lending staff/administration, problem loan trends, credit risk concentrations, loan review results, changes in the value of underlying collateral for loans, and changes in the regulatory and business environment.

Certain loans are individually evaluated for estimated credit losses, including those greater than $500,000 that are classified as substandard or doubtful and are on nonaccrual or that have other unique characteristics differing from the segment. Specific reserves are established when appropriate for such loans based on the present value of expected future cash flows of the loan or the estimated realizable value of the collateral, if any.

Management may also adjust its assumptions to account for differences between expected and actual losses from period-to-period. The variability of management's assumptions could alter the ACL on loans materially and impact future results of operations and financial condition. The loss estimation models and methods used to determine the ACL are continually refined and enhanced.

Allowance for Credit Losses on Off-Balance Sheet Credit Exposures: The ACL on off-balance sheet credit exposures is a component of Accrued interest and other liabilities on the Company's consolidated balance sheets and represents the estimate of probable credit losses inherent in unfunded commitments to extend credit as of the balance sheet date. Unfunded commitments to extend credit include unused portions of lines of credit, commitments to originate loans and standby and commercial letters of credit. The process used to determine the ACL for these exposures is consistent with the process for determining the ACL on loans, as adjusted for estimated funding probabilities or loan equivalency factors. A charge or credit to Credit loss expense on the consolidated statements of income is made to account for the change in the ACL on off-balance sheet exposures between reporting periods.

Accrued Interest: Upon adoption of CECL on January 1, 2023, the Company elected to present accrued interest receivable balances in Other assets on the consolidated balance sheets and exclude accrued interest from the ACL on loans and AFS debt securities. The Company will continue to write-off accrued interest receivable by reversing interest income when a security or loan is placed in nonaccrual, which is generally when payments on a security or loan are 90 days or more past due.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The guidance in the ASU requires that expected credit losses for financial assets held at the reporting date that are accounted for at amortized cost be measured and recognized based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. A modified version of these requirements also applies to debt securities classified as AFS. The ASU became effective for the Company beginning with the 2023 fiscal year. The impact of the ASU on the Company's consolidated financial statements is discussed in Note 1, Summary of Significant Accounting Policies.

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and has issued subsequent amendments thereto, which provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2024. The transition away from LIBOR is not expected to have a material impact on the Company's consolidated financial statements.

In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings (TDRs) and Vintage Disclosures. The guidance amends ASC 326 to eliminate the accounting guidance for TDRs by creditors, while enhancing disclosure requirements for certain loan refinancing and restructuring activities by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying TDR recognition and measurement guidance, creditors will determine whether a modification results in a new loan or continuation of an existing loan. These amendments are also intended to enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, the amendments to ASC 326 require that an entity disclose current-period gross write-offs by year of origination within the vintage disclosures, which requires that an entity disclose the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination. The guidance is only for entities that have adopted the amendments in ASU No. 2016-13 for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company

adopted ASU No. 2022-02 effective January 1, 2023. The adoption of the provisions contained within ASU No. 2022-02 did not have a material impact on the consolidated financial statements.

In March 2023, the FASB issued ASU No. 2023-02, Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU No. 2014-01, Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects, previously introduced the option to apply the proportional amortization method to account for investments made primarily for the purpose of receiving income tax credits and other income tax benefits when certain requirements are met; however, this guidance limited the proportional amortization method to investments in low-income-housing tax credit (LIHTC) structures. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense (benefit). Equity investments in other tax credit structures are typically accounted for using the equity method, which results in investment income, gains and losses, and tax credits being presented gross on the income statement in their respective line items. The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. The amendments in this update are effective for the Company for fiscal years beginning after December 31, 2023, including interim periods within those fiscal years. Early adoption is permitted in any interim period. If early adoption is elected, adoption must be as of the beginning of the fiscal year that includes the interim period of adoption. The amendments in this update must be applied on either a modified retrospective or a retrospective basis. The Company has not elected early adoption and is currently evaluating the impact of this standard for its tax equity investments and the impact to noninterest income, noninterest expense, and income tax expense within the consolidated financial statements.

Loans

Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their unpaid principal balances, adjusted for any charge-offs, the ACL, and any deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans.

Loan interest income is accrued daily on outstanding balances. The following accounting policies, related to accrual and nonaccrual loans, apply to all portfolio segments and loan classes, which the Company considers to be the same. The accrual of interest is normally discontinued when a loan is specifically determined to be impaired and/or management believes, after considering collection efforts and other factors, that the borrower's financial condition is such that collection of interest is doubtful. In general, loans that are 90 days or more past due are placed in nonaccrual, unless there are circumstances that cause management to believe the collection of interest is not doubtful. Generally, any unpaid interest previously accrued on those loans is reversed against current period interest income. A loan may be restored to accrual status when its financial status has significantly improved and there is no principal or interest past due. A loan may also be restored to accrual status if the borrower makes six consecutive monthly payments or the lump sum equivalent. Income on nonaccrual loans is generally not recognized unless a loan is returned to accrual status or after all principal has been collected. Interest payments received on such loans are generally applied as a reduction of the loan principal balance. Delinquency status is determined based on contractual terms for all portfolio segments and loan classes. Loans past due 30 days or more are considered delinquent. Loans are considered in process of foreclosure when a judgment of foreclosure has been issued by the court.

Loan origination fees and direct loan origination costs are deferred and amortized as an adjustment of the related loan's yield using methods that approximate the interest method. The Company generally amortizes these amounts over the estimated average life of the related loans.

Allowance for Credit Losses on Loans 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 under the incurred loss model in accordance with previously applicable GAAP as described in the 2022 Annual Report.

The level of the ACL on loans represents management's estimate of expected credit losses over the expected life of the loans at the balance sheet date. For all loan classes, loan losses are charged against the ACL on loans when management believes the loan balance is uncollectible or in accordance with federal guidelines. Subsequent recoveries, if any, are credited to the ACL on loans.

Upon adoption of CECL on January 1, 2023, the Company replaced the incurred loss model that recognizes losses when it becomes probable that a credit loss will be incurred, with a requirement to recognize lifetime expected credit losses based on historical experience and current and reasonably supportable forecasted conditions to reflect the full amount of expected credit losses. The ACL on loans is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. The ACL on loans is comprised of reserves measured on a collective (pool) basis based on a lifetime loss-rate model when similar risk characteristics exist. Loans that do not share risk characteristics are evaluated on an individual basis, generally larger non-accruing commercial loans.

Risk characteristics relevant to each portfolio segment are as follows:

•Residential real estate - Loans in this segment are collateralized by owner-occupied 1-4 family residential real estate, second and vacation homes, 1-4 family investment properties, home equity and second mortgage loans. Repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, could have an effect on the credit quality of this segment.

•Construction real estate - Loans in this segment include residential and commercial construction properties, commercial real estate development loans (while in the construction phase of the projects), land and land development loans.

Repayment is dependent on the credit quality of the individual borrower and/or the underlying cash flows generated by the properties being constructed. The overall health of the economy, including unemployment rates, housing prices, vacancy rates and material costs, could have an effect on the credit quality of this segment.

•Commercial real estate - Loans in this segment are primarily properties occupied by businesses or income-producing properties. The underlying cash flows generated by the properties may be adversely impacted by a downturn in the economy as evidenced by a general slowdown in business or increased vacancy rates which, in turn, could have an effect on the credit quality of this segment. Management requests business financial statements at least annually and monitors the cash flows of these loans.

•Commercial - Loans in this segment are made to businesses and are generally secured by non-real estate assets of the business. Repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer or business spending, could have an effect on the credit quality of this segment.

•Consumer - Loans in this segment are made to individuals for personal expenditures, such as an automobile purchase, and include unsecured loans. Repayment is primarily dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment, could have an effect on the credit quality of this segment.

•Municipal - Loans in this segment are made to municipalities located within the Company's service area. Repayment is primarily dependent on taxes or other funds collected by the municipalities. Management considers there to be minimal risk surrounding the credit quality of this segment.

Other Comprehensive Income (Loss)

Other Comprehensive Income (Loss)Accounting principles generally require recognized revenue, expenses, gains and losses be included in net income or loss. Certain changes in assets and liabilities, such as the after tax effect of unrealized gains and losses on investment securities AFS that have not been recorded through an ACL are not reflected in the consolidated statements of income. The cumulative effect of such items, net of tax effect, is reported as a separate component of the equity section of the consolidated balance sheets (Accumulated OCI). OCI, along with net income, comprises the Company's total comprehensive income or loss.

Fair Value Measurement

The Company utilizes FASB ASC Topic 820, Fair Value Measurement, as guidance for accounting for assets and liabilities carried at fair value. This standard defines fair value as the price that would be received, without adjustment for transaction costs, to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The guidance in FASB ASC Topic 820 establishes a three-level fair value hierarchy, which prioritizes the inputs used in measuring fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The three levels of the fair value hierarchy are:

•Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

•Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;

•Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

Fair Value Measurement

The following is a description of the valuation methodologies used for the Company’s assets that are measured on a recurring basis at estimated fair value:

Investment securities AFS: Certain U.S. Treasury notes have been valued using unadjusted quoted prices from active markets and therefore have been classified as Level 1. However, the majority of the Company’s AFS securities have been valued utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include market maker bids, quotes and pricing models. Inputs to the pricing models include recent trades, benchmark interest rates, spreads and actual and projected cash flows.

Mutual funds: Mutual funds have been valued using unadjusted quoted prices from active markets and therefore have been classified as Level 1.
