Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation. The consolidated financial statements in this quarterly report on Form 10-Q include the accounts of the Company and all other entities in which Origin Bancorp, Inc. has a controlling financial interest, including the Bank and Forth Insurance, LLC. All significant intercompany balances and transactions have been eliminated in consolidation. The Company’s accounting and financial reporting policies conform, in all material respects, to generally accepted accounting principles in the United States (“U.S. GAAP”) and to general practices within the financial services industry. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued. The consolidated financial statements in this quarterly report on Form 10-Q have not been audited by an independent registered public accounting firm, excluding the figures as of December 31, 2023, but in the opinion of management, reflect all adjustments (which are of a normal recurring nature) necessary for a fair presentation of the Company’s financial position and results of operations for the periods presented. These consolidated financial statements of the Company have been prepared in accordance with U.S. GAAP and with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2023, included in the Company’s annual report on Form 10-K (“2023 Form 10-K”) filed with the SEC. Operating results for the interim periods disclosed herein are not necessarily indicative of results that may be expected for a full year. Certain prior period amounts have been reclassified to conform to the current year financial statement presentations. These reclassifications did not impact previously reported net income or comprehensive income (loss).
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information that affect the amounts reported in the financial statements and disclosures provided, including the accompanying notes, and actual results could differ. Material estimates that are particularly susceptible to change include the allowance for credit losses for loans, off-balance sheet commitments and available for sale securities; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the Company’s consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual results could differ from those estimates.
Reclassifications	Reclassifications. Certain amounts previously reported have been reclassified to conform to the current presentation. Such reclassifications had no effect on prior year net income or stockholders’ equity.
Investments in Tax Credit Entities	Investments in Tax Credit Entities. As part of its Community Reinvestment Act responsibilities and due to their favorable economic characteristics, the Company invests in tax credit-motivated projects primarily in the markets it serves. These projects are directed at tax credits issued under Low-Income Housing Tax Credits (“LIHTC”). The Company generates returns on tax credit motivated projects through the receipt of federal, and if applicable, state tax credits. The federal tax credits are recorded as an offset to the income tax provision in the year that they are earned under federal income tax law over 10 to 15 years beginning in the year in which rental activity commences. These credits, if not used in the tax return for the year of origination, can be carried forward for 20 years. The Company invests in a tax credit entity, usually an LLC, which owns the real estate. The Company receives a nonvoting interest in the entity that must be retained during the compliance period for the credits (15 years for Low-Income Housing Tax Credit programs). Control of the tax credit entity rests in the 0.1% interest general partner, who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. Due to the lack of any voting, economic, or managerial control, and due to the contractual reduction in the investment, the Company accounts for its investment by amortizing the investment, beginning at the issuance of the certificate of occupancy of the project, over the compliance period, as management believes any potential residual value in the real estate will have limited value. Amortization is included as a component of income tax expense and for the three months ended March 31, 2024 and 2023, was $415,000 and $453,000, respectively. The income tax credits and other income tax benefits recognized for the three months ended March 31, 2024 and 2023, was $504,000 and $569,000, respectively, and was included as a component of income tax expense on the Consolidated Statements of Income. The Company has the risk of credit recapture if the projects do not maintain compliance during the compliance period. No such events have occurred to date.
Effect of Recently Adopted Accounting Standards and Effect of Newly Issued But Not Yet Effective Accounting Standards	Effect of Recently Adopted Accounting Standards ASU No. 2021-08, Business Combinations (Topic 805) — Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this Update affect accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company’s financial statements or disclosures. ASU No. 2022-01, Derivatives and Hedging (Topic 815) — Fair Value Hedging - Portfolio Layer Method. The amendments in this Update clarify the accounting for and promote consistency in the reporting of hedge basis adjustments applicable to both a single hedged layer and multiple hedged layers. Additionally, this Update allows entities to elect to apply the portfolio layer method of hedge accounting in accordance with Topic 815. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company’s financial statements or disclosures. ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326) — Troubled Debt Restructurings and Vintage Disclosures. The amendments in this Update eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. For public business entities, the amendments in this Update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company’s financial statements or disclosures. ASU No. 2022-06, Reference Rate Reform (Topic 848) - Deferral of the Sunset Date of Topic 848 — The amendments in this Update provide temporary relief during the transition period in complying with Update No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The Board included a sunset provision within Topic 848 based on expectations of when the London Interbank Offered Rate (LIBOR) would cease being published. At the time that Update 2020-04 was issued, the UK Financial Conduct Authority (FCA) had established its intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022 - 12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of the overnight 1-, 3-, 6-, and 12-month tenors of USD LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848. Because the relief in Topic 848 may not cover a period of time during which a significant number of modifications may take place, the amendments in this Update defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. The ASU is effective immediately. Implementation of this ASU did not materially impact the Company's financial statements or disclosures. ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method — The amendments in this Update allow entities to elect to account for equity investments made primarily for the purpose of receiving income tax credits using the proportional amortization method, regardless of the tax credit program through which the investment earns income tax credits, if certain conditions are met. The amendments in this Update also eliminate certain low income housing tax credits (“LIHTC”)-specific guidance to align the accounting more closely for LIHTCs with the accounting for other equity investments in tax credit structures and require that the delayed equity contribution guidance apply only to tax equity investments accounted for using the proportional amortization method. The ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company's financial statements or disclosures. Effect of Newly Issued But Not Yet Effective Accounting Standards ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures — The amendments in this Update improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this Update: 1.Require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss (collectively referred to as the “significant expense principle”). 2.Require that a public entity disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the segment expenses disclosed under the significant expense principle and each reported measure of segment profit or loss. 3.Require that a public entity provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 in interim periods. 4.Clarify that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure, if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity’s consolidated financial statements. In other words, in addition to the measure that is most consistent with the measurement principles under generally accepted accounting principles (GAAP), a public entity is not precluded from reporting additional measures of a segment’s profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources. 5.Require that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. 6.Require that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this Update and all existing segment disclosures in Topic 280. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Retrospective application to all periods presented in the financial statements is required. The Company is evaluating the impact of this ASU on its consolidated financial statements and disclosures. ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures — The amendments in this Update, on an annual basis, require that public business entities (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Specifically, public business entities are required to disclose a tabular reconciliation, using both percentages and reporting currency amounts, for specific listed categories. The ASU is effective for fiscal years beginning after December 15, 2024, including interim periods within those fiscal years. The Company is evaluating the impact of this ASU on its consolidated financial statements and disclosures.
Fair Value of Financial Instruments	Fair value is the exchange price that is expected to be received for an asset or paid to transfer a liability (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. Certain assets and liabilities are recorded in the Company’s consolidated financial statements at fair value. Some are recorded on a recurring basis and some on a nonrecurring basis. The Company utilizes fair value measurement to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach to estimate the fair values of its financial instruments. Such valuation techniques are consistently applied. A hierarchy for fair value has been established, which categorizes the valuation techniques into three levels used to measure fair value. The three levels are as follows: Level 1 - Fair value is based on unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 - Fair value is based on significant other observable inputs that are generally determined based on a single price for each financial instrument provided to the Company by an unrelated third-party pricing service and is based on one or more of the following: •Quoted prices for similar, but not identical, assets or liabilities in active markets; •Quoted prices for identical or similar assets or liabilities in markets that are not active; •Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; and •Other inputs derived from or corroborated by observable market inputs. Level 3 - Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects the Company’s own assumptions about the risk premiums that market participants would generally require and the assumptions they would use. These estimates can be inherently uncertain. Securities Available for Sale Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 or Level 3 inputs. For Level 1 securities, the Company obtains the fair value measurements for those identical assets from an independent pricing service. For Level 2 securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, market consensus prepayment speeds, credit information and the security's terms and conditions, among other things. In order to ensure the fair values are consistent with ASC 820, Fair Value Measurements and Disclosures, the Company periodically checks the fair value by comparing them to other pricing sources, such as Bloomberg LP. The third-party pricing service is subject to an annual review of internal controls in accordance with the Statement on Standards for Attestation Engagements No. 16, which was made available to the Company. In certain cases where Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. For level 3 securities, the Company determines the fair value of the instruments based on their callability, putability and prepay optionality. Putable instruments are valued at book value, non-putable instruments are priced mainly using a present value calculation based on the spread to the yield curve. Derivatives Fair values for interest rate swap agreements and interest rate lock commitments are based upon the amounts that would be required to settle the contracts. Fair values for risk participations and loan sale commitments are based on the fair values of the underlying mortgage loans or securities and the probability of such commitments being exercised. Significant management judgment and estimation is required in determining these fair value measurements. Fair Values of Assets Recorded on a Recurring Basis for which the Fair Value Option has been Elected Certain assets are measured at fair value on a recurring basis due to the Company’s election to adopt fair value accounting treatment for those assets. This election allows for a more effective offset of the changes in fair values of the assets and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC Topic 815, Derivatives and Hedging. For assets for which the fair value has been elected, the earned current contractual interest payment is recognized in interest income. The following methodologies were used to measure the fair value of financial assets valued on a recurring basis for which the fair value option was elected: Securities at Fair Value through Income Securities carried at fair value through income are valued using a discounted cash flow with a credit spread applied to each instrument based on the creditworthiness of each issuer. Credit spreads ranged from 83 to 227 basis points at both March 31, 2024, and December 31, 2023. The Company believes the fair value approximates an exit price. Loans Held for Sale Fair values for loans held for sale are established using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price. Fair Value of Assets Recorded on a Nonrecurring Basis Non-marketable equity securities held in other financial institutions The majority of the Company’s non-marketable equity securities held in other financial institutions qualify for the practical expedient allowed for equity securities without a readily determinable fair values, such that the Company has elected to carry these securities at cost adjusted for any observable transactions during the period, less any impairment. Non-marketable equity securities held in other financial institutions totaled $53.9 million and $55.2 million at March 31, 2024 and December 31, 2023, respectively, and are shown on the face of the consolidated balance sheets. To date, no impairment has been recorded on the Company's investments in equity securities that do not have readily determinable fair values. Individually Evaluated Loans with Credit Losses Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured to determine if any credit loss exists. Allowable methods for determining the amount of credit loss include estimating the fair value using the fair value of the collateral for collateral-dependent loans and a discounted cash flow methodology for other evaluated loans that are not collateral dependent. If the loan is identified as collateral-dependent, the fair value method of measuring the amount of credit loss is utilized. Evaluating the fair value of the collateral for collateral-dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. If the loan is not collateral-dependent, the discounted cash flow method is utilized, which involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate. Loans that have experienced a credit loss with specific allocated losses are within Level 3 of the fair value hierarchy when the credit loss is determined using the fair value method. The fair value of collateral-dependent loans that have specific allocated reserves was approximately $3.9 million and $3.8 million at March 31, 2024, and December 31, 2023, respectively. Non-Financial Assets Foreclosed assets held for sale are the only non-financial assets valued on a nonrecurring basis that are initially recorded by the Company at fair value, less estimated costs to sell. At foreclosure, if the fair value, less estimated costs to sell, of the real estate acquired is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the ALCL. Additionally, valuations are periodically performed by management, and any subsequent reduction in value is recognized by a charge to income. The carrying value and fair value of foreclosed assets held for sale was estimated using Level 3 inputs based on observable market data
Derivative Instruments and Hedging Activities	Risk Management Objective of Using Derivatives The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments, as well as to manage changes in fair values of some assets which are marked at fair value through the consolidated statement of income on a recurring basis. Cash Flow Hedges of Interest Rate Risk The Company is a party to interest rate swap agreements under which the Company receives interest at a variable rate and pays at a fixed rate. The derivative instruments represented by these swap agreements are designated as cash flow hedges of the Company’s forecasted variable cash flows under a variable-rate term borrowing agreements. During the terms of the swap agreements, the effective portion of changes in the fair value of the derivative instruments are recorded in accumulated other comprehensive (loss) income and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. There was no ineffective portion of the change in fair value of the derivatives recognized directly in earnings. The entire swap fair value will be reclassified into earnings before the expiration dates of the swap agreements. Derivatives Not Designated as Hedges Customer interest rate derivative program The Company offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. In most instances, the Company acts only as an intermediary, simultaneously entering into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions without significantly impacting its results of operations. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and any offsetting derivatives are recognized directly in earnings as a component of noninterest income. From time to time, the Company shares in credit risk on interest rate swap arrangements, by entering into risk participation agreements with syndication partners. These are accounted for at fair value and disclosed as risk participation derivatives. Mortgage banking derivatives As part of its mortgage banking and related risk management activities, the Company enters into interest rate lock commitment (“IRLC”) agreements on prospective residential mortgage loans. These IRLCs are derivative financial instruments and the fair value of these IRLCs are included in other assets. The Company also economically hedged the value of MSRs by entering into a series of commitments to purchase mortgage-backed securities in the future and U.S. Treasury Notes. Some interest rate swaps included in other assets were subject to a master netting arrangement with the counterparty in all periods presented and could be offset against some amounts included in interest rate swaps included in other liabilities. The Company has chosen not to net these exposures in the consolidated balance sheets, and any impact of netting these amounts would not be significant.

Basis of Presentation. The consolidated financial statements in this quarterly report on Form 10-Q include the accounts of the Company and all other entities in which Origin Bancorp, Inc. has a controlling financial interest, including the Bank and Forth Insurance, LLC. All significant intercompany balances and transactions have been eliminated in consolidation. The Company’s accounting and financial reporting policies conform, in all material respects, to generally accepted accounting principles in the United States (“U.S. GAAP”) and to general practices within the financial services industry. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued.

The consolidated financial statements in this quarterly report on Form 10-Q have not been audited by an independent registered public accounting firm, excluding the figures as of December 31, 2023, but in the opinion of management, reflect all adjustments (which are of a normal recurring nature) necessary for a fair presentation of the Company’s financial position and results of operations for the periods presented. These consolidated financial statements of the Company have been prepared in accordance with U.S. GAAP and with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial reporting. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements.

These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2023, included in the Company’s annual report on Form 10-K (“2023 Form 10-K”) filed with the SEC. Operating results for the interim periods disclosed herein are not necessarily indicative of results that may be expected for a full year. Certain prior period amounts have been reclassified to conform to the current year financial statement presentations. These reclassifications did not impact previously reported net income or comprehensive income (loss).

Use of Estimates

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions based on available information that affect the amounts reported in the financial statements and disclosures provided, including the accompanying notes, and actual results could differ. Material estimates that are particularly susceptible to change include the allowance for credit losses for loans, off-balance sheet commitments and available for sale securities; fair value measurements of assets and liabilities; and income taxes. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the Company’s consolidated financial statements in the period they are deemed necessary. While management uses its best judgment, actual results could differ from those estimates.

Reclassifications

Reclassifications. Certain amounts previously reported have been reclassified to conform to the current presentation. Such reclassifications had no effect on prior year net income or stockholders’ equity.

Investments in Tax Credit Entities

Investments in Tax Credit Entities. As part of its Community Reinvestment Act responsibilities and due to their favorable economic characteristics, the Company invests in tax credit-motivated projects primarily in the markets it serves. These projects are directed at tax credits issued under Low-Income Housing Tax Credits (“LIHTC”). The Company generates returns on tax credit motivated projects through the receipt of federal, and if applicable, state tax credits. The federal tax credits are recorded as an offset to the income tax provision in the year that they are earned under federal income tax law over 10 to 15 years beginning in the year in which rental activity commences. These credits, if not used in the tax return for the year of origination, can be carried forward for 20 years.

The Company invests in a tax credit entity, usually an LLC, which owns the real estate. The Company receives a nonvoting interest in the entity that must be retained during the compliance period for the credits (15 years for Low-Income Housing Tax Credit programs). Control of the tax credit entity rests in the 0.1% interest general partner, who has the power and authority to make decisions that impact economic performance of the project and is required to oversee and manage the project. Due to the lack of any voting, economic, or managerial control, and due to the contractual reduction in the investment, the Company accounts for its investment by amortizing the investment, beginning at the issuance of the certificate of occupancy of the project, over the compliance period, as management believes any potential residual value in the real estate will have limited value. Amortization is included as a component of income tax expense and for the three months ended March 31, 2024 and 2023, was $415,000 and $453,000, respectively. The income tax credits and other income tax benefits recognized for the three months ended March 31, 2024 and 2023, was $504,000 and $569,000, respectively, and was included as a component of income tax expense on the Consolidated Statements of Income.

The Company has the risk of credit recapture if the projects do not maintain compliance during the compliance period. No such events have occurred to date.

Effect of Recently Adopted Accounting Standards and Effect of Newly Issued But Not Yet Effective Accounting Standards

Effect of Recently Adopted Accounting Standards

ASU No. 2021-08, Business Combinations (Topic 805) — Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this Update affect accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company’s financial statements or disclosures.

ASU No. 2022-01, Derivatives and Hedging (Topic 815) — Fair Value Hedging - Portfolio Layer Method. The amendments in this Update clarify the accounting for and promote consistency in the reporting of hedge basis adjustments applicable to both a single hedged layer and multiple hedged layers. Additionally, this Update allows entities to elect to apply the portfolio layer method of hedge accounting in accordance with Topic 815. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company’s financial statements or disclosures.

ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326) — Troubled Debt Restructurings and Vintage Disclosures. The amendments in this Update eliminate the accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Specifically, rather than applying the recognition and measurement guidance for TDRs, an entity must apply the loan refinancing and restructuring guidance in paragraphs 310-20-35-9 through 35-11 to determine whether a modification results in a new loan or a continuation of an existing loan. For public business entities, the amendments in this Update require that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company’s financial statements or disclosures.

ASU No. 2022-06, Reference Rate Reform (Topic 848) - Deferral of the Sunset Date of Topic 848 — The amendments in this Update provide temporary relief during the transition period in complying with Update No. 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The Board included a sunset provision within Topic 848 based on expectations of when the London Interbank Offered Rate (LIBOR) would cease being published. At the time that Update 2020-04 was issued, the UK Financial Conduct Authority (FCA) had established its intent that it would no longer be necessary to persuade, or compel, banks to submit to LIBOR after December 31, 2021. As a result, the sunset provision was set for December 31, 2022 - 12 months after the expected cessation date of all currencies and tenors of LIBOR. In March 2021, the FCA announced that the intended cessation date of the overnight 1-, 3-, 6-, and 12-month tenors of USD LIBOR would be June 30, 2023, which is beyond the current sunset date of Topic 848.

Because the relief in Topic 848 may not cover a period of time during which a significant number of modifications may take place, the amendments in this Update defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. The ASU is effective immediately. Implementation of this ASU did not materially impact the Company's financial statements or disclosures.

ASU No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method — The amendments in this Update allow entities to elect to account for equity investments made primarily for the purpose of receiving income tax credits using the proportional amortization method, regardless of the tax credit program through which the investment earns income tax credits, if certain conditions are met. The amendments in this Update also eliminate certain low income housing tax credits (“LIHTC”)-specific guidance to align the accounting more closely for LIHTCs with the accounting for other equity investments in tax credit structures and require that the delayed equity contribution guidance apply only to tax equity investments accounted for using the proportional amortization method. The ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Implementation of this ASU did not materially impact the Company's financial statements or disclosures.

Effect of Newly Issued But Not Yet Effective Accounting Standards

ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures — The amendments in this Update improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this Update:

1.Require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss (collectively referred to as the “significant expense principle”).

2.Require that a public entity disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition. The other segment items category is the difference between segment revenue less the segment expenses disclosed under the significant expense principle and each reported measure of segment profit or loss.

3.Require that a public entity provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by Topic 280 in interim periods.

4.Clarify that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure, if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity’s consolidated financial statements. In other words, in addition to the measure that is most consistent with the measurement principles under generally accepted accounting principles (GAAP), a public entity is not precluded from reporting additional measures of a segment’s profit or loss that are used by the CODM in assessing segment performance and deciding how to allocate resources.

5.Require that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources.

6.Require that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this Update and all existing segment disclosures in Topic 280.

Fair Value of Financial Instruments

Fair value is the exchange price that is expected to be received for an asset or paid to transfer a liability (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. Certain assets and liabilities are recorded in the Company’s consolidated financial statements at fair value. Some are recorded on a recurring basis and some on a nonrecurring basis.

The Company utilizes fair value measurement to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach to estimate the fair values of its financial instruments. Such valuation techniques are consistently applied.

A hierarchy for fair value has been established, which categorizes the valuation techniques into three levels used to measure fair value. The three levels are as follows:

Level 1 - Fair value is based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Fair value is based on significant other observable inputs that are generally determined based on a single price for each financial instrument provided to the Company by an unrelated third-party pricing service and is based on one or more of the following:

•Quoted prices for similar, but not identical, assets or liabilities in active markets;

•Quoted prices for identical or similar assets or liabilities in markets that are not active;

•Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; and

•Other inputs derived from or corroborated by observable market inputs.

Level 3 - Prices or valuation techniques that require inputs that are both significant and unobservable in the market. These instruments are valued using the best information available, some of which is internally developed, and reflects the Company’s own assumptions about the risk premiums that market participants would generally require and the assumptions they would use. These estimates can be inherently uncertain.

Securities Available for Sale

Securities classified as available for sale are reported at fair value utilizing Level 1, Level 2 or Level 3 inputs. For Level 1 securities, the Company obtains the fair value measurements for those identical assets from an independent pricing service. For Level 2 securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, market consensus prepayment speeds, credit information and the security's terms and conditions, among other things. In order to ensure the fair values are consistent with ASC 820, Fair Value Measurements and Disclosures, the Company periodically checks the fair value by comparing them to other pricing sources, such as Bloomberg LP. The third-party pricing service is subject to an annual review of internal controls in accordance with the Statement on Standards for Attestation Engagements No. 16, which was made available to the Company. In certain cases where Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. For level 3 securities, the Company determines the fair value of the instruments based on their callability, putability and prepay optionality. Putable instruments are valued at book value, non-putable instruments are priced mainly using a present value calculation based on the spread to the yield curve.

Derivatives

Fair values for interest rate swap agreements and interest rate lock commitments are based upon the amounts that would be required to settle the contracts. Fair values for risk participations and loan sale commitments are based on the fair values of the underlying mortgage loans or securities and the probability of such commitments being exercised. Significant management judgment and estimation is required in determining these fair value measurements.

Fair Values of Assets Recorded on a Recurring Basis for which the Fair Value Option has been Elected

Certain assets are measured at fair value on a recurring basis due to the Company’s election to adopt fair value accounting treatment for those assets. This election allows for a more effective offset of the changes in fair values of the assets and the derivative instruments used to economically hedge them without the burden of complying with the requirements for hedge accounting under ASC Topic 815, Derivatives and Hedging. For assets for which the fair value has been elected, the earned current contractual interest payment is recognized in interest income.

The following methodologies were used to measure the fair value of financial assets valued on a recurring basis for which the fair value option was elected:

Securities at Fair Value through Income

Securities carried at fair value through income are valued using a discounted cash flow with a credit spread applied to each instrument based on the creditworthiness of each issuer. Credit spreads ranged from 83 to 227 basis points at both March 31, 2024, and December 31, 2023. The Company believes the fair value approximates an exit price.

Loans Held for Sale

Fair values for loans held for sale are established using anticipated sale prices for loans allocated to a sale commitment, and those unallocated to a commitment are valued based on the interest rate and term for similar loans allocated. The Company believes the fair value approximates an exit price.

Fair Value of Assets Recorded on a Nonrecurring Basis

Non-marketable equity securities held in other financial institutions

The majority of the Company’s non-marketable equity securities held in other financial institutions qualify for the practical expedient allowed for equity securities without a readily determinable fair values, such that the Company has elected to carry these securities at cost adjusted for any observable transactions during the period, less any impairment. Non-marketable equity securities held in other financial institutions totaled $53.9 million and $55.2 million at March 31, 2024 and December 31, 2023, respectively, and are shown on the face of the consolidated balance sheets. To date, no impairment has been recorded on the Company's investments in equity securities that do not have readily determinable fair values.

Individually Evaluated Loans with Credit Losses

Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured to determine if any credit loss exists. Allowable methods for determining the amount of credit loss include estimating the fair value using the fair value of the collateral for collateral-dependent loans and a discounted cash flow methodology for other evaluated loans that are not collateral dependent. If the loan is identified as collateral-dependent, the fair value method of measuring the amount of credit loss is utilized. Evaluating the fair value of the collateral for collateral-dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. If the loan is not collateral-dependent, the discounted cash flow method is utilized, which involves assumptions and judgments as to credit risk, prepayment risk, liquidity risk, default rates, loss severity, payment speeds, collateral values and discount rate. Loans that have experienced a credit loss with specific allocated losses are within Level 3 of the fair value hierarchy when the credit loss is determined using the fair value method. The fair value of collateral-dependent loans that have specific allocated reserves was approximately $3.9 million and $3.8 million at March 31, 2024, and December 31, 2023, respectively.

Non-Financial Assets

Foreclosed assets held for sale are the only non-financial assets valued on a nonrecurring basis that are initially recorded by the Company at fair value, less estimated costs to sell. At foreclosure, if the fair value, less estimated costs to sell, of the real estate acquired is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the ALCL. Additionally, valuations are periodically performed by management, and any subsequent reduction in value is recognized by a charge to income. The carrying value and fair value of foreclosed assets held for sale was estimated using Level 3 inputs based on observable market data

Derivative Instruments and Hedging Activities

Risk Management Objective of Using Derivatives

The Company enters into derivative financial instruments to manage risks related to differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments, as well as to manage changes in fair values of some assets which are marked at fair value through the consolidated statement of income on a recurring basis.

Cash Flow Hedges of Interest Rate Risk

The Company is a party to interest rate swap agreements under which the Company receives interest at a variable rate and pays at a fixed rate. The derivative instruments represented by these swap agreements are designated as cash flow hedges of the Company’s forecasted variable cash flows under a variable-rate term borrowing agreements. During the terms of the swap agreements, the effective portion of changes in the fair value of the derivative instruments are recorded in accumulated other comprehensive (loss) income and subsequently reclassified into earnings in the periods that the hedged forecasted variable-rate interest payments affected earnings. There was no ineffective portion of the change in fair value of the derivatives recognized directly in earnings. The entire swap fair value will be reclassified into earnings before the expiration dates of the swap agreements.

Derivatives Not Designated as Hedges

Customer interest rate derivative program

The Company offers certain derivatives products, primarily interest rate swaps, directly to qualified commercial banking customers to facilitate their risk management strategies. In most instances, the Company acts only as an intermediary, simultaneously entering into offsetting agreements with unrelated financial institutions, thereby mitigating its net risk exposure resulting from such transactions without significantly impacting its results of operations. Because the interest rate derivatives associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer derivatives and any offsetting derivatives are recognized directly in earnings as a component of noninterest income.

From time to time, the Company shares in credit risk on interest rate swap arrangements, by entering into risk participation agreements with syndication partners. These are accounted for at fair value and disclosed as risk participation derivatives.

Mortgage banking derivatives

As part of its mortgage banking and related risk management activities, the Company enters into interest rate lock commitment (“IRLC”) agreements on prospective residential mortgage loans. These IRLCs are derivative financial instruments and the fair value of these IRLCs are included in other assets. The Company also economically hedged the value of MSRs by entering into a series of commitments to purchase mortgage-backed securities in the future and U.S. Treasury Notes.

Some interest rate swaps included in other assets were subject to a master netting arrangement with the counterparty in all periods presented and could be offset against some amounts included in interest rate swaps included in other liabilities. The Company has chosen not to net these exposures in the consolidated balance sheets, and any impact of netting these amounts would not be significant.
