Basis of Presentation and Significant Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Note 1—Basis of Presentation and Significant Accounting Policies The accompanying unaudited condensed consolidated financial statements include the accounts of Farmers & Merchants Bancorp (“FMCB” or “Bancorp”), a bank holding company incorporated in the State of Delaware and its wholly owned subsidiary, Farmers & Merchants Bank of Central Californi a (“F&M Bank” or the “Bank”) collectively These unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In preparing these financial statements, the Company has evaluated events and transactions subsequent to March 31, 2023 for potential recognition or disclosure. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and note disclosures have been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements. All significant intercompany transactions and balances have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Various elements of the Company’s accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. In particular, management has identified several accounting policies that, due to the judgments, estimates and assumptions inherent in those policies, are significant to an understanding of Bank’s financial statements. These policies relate to: (i) the methodology for the recognition of interest income; (ii) the determination of the provision and allowance for credit losses; (iii) the valuation of financial assets and liabilities recorded at fair value; (iv) the valuation of intangibles, such as goodwill and core deposit intangibles (“CDI”); (v) the valuation of other real estate owned (“OREO”); and (vi) the valuation or recognition of deferred tax assets and liabilities. These policies and judgments, estimates and assumptions are described in greater detail in subsequent notes to the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations, Summary of Critical Accounting Policies and Estimates, in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 15, 2023 and Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations Summary of Critical Accounting Policies and Estimates included in this Quarterly Report on Form 10-Q. The information included in this Form 10-Q should be read in conjunction with our 2022 Form 10-K. Interim results are not necessarily indicative of results for a full year or any other interim period. Accounting Standards Pending Adoption — The following paragraphs provide descriptions of newly issued but not yet effective accounting standards that could have a material effect on the Company’s financial position or results of operations. In March 2020, the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) issued ASU . ASU 2020-04 was effective upon issuance and, based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. We have not elected to apply these amendments. However, we will assess the applicabil In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848). The main amendments in this ASU are intended to clarify certain optional expedients and scope of derivative instruments. The amendments are elective and effective immediately upon issuance of this ASU. ASU 2021-01 was effective upon issuance and, based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. We have not elected to apply amendments; however, will assess the applicability of this ASU to us as we continue to monitor guidance for reference rate reform from FASB and its impact on our financial condition and results of operations. ASU No. 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” ASU 2022-06 extends the period of time preparers can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06, which was effective upon issuance, defers the sunset date of this prior guidance from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. We have not elected to apply amendments at this time, however, will assess the applicability of this ASU to us as we continue to monitor guidance for reference rate reform from FASB and its impact on our financial condition and results of operations. In June 2022, the FASB issued guidance within ASU 2022-03, Fair Value Measurement of Equity Securities Subject to contractual Sale Restrictions. The amendments in this ASU affect all entities that have investments in equity securities measured at fair value that are subject to a contractual sale restriction. These amendments clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments in this ASU are effective for fiscal years, beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The adoption of this ASU is not expected to have material impact on the Company’s Consolidated Financial Statements In March 2023, the FASB issued ASU 2023-02, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The Amendments in ASU 2023-02 apply to all reporting entities that hold (1) tax equity investments that meet the conditions for and elect to account for them using the proportional amortization method or (2) an investment in a LIHTC structure through a limited liability entity that is not accounted for using the proportional amortization method and to which certain LIHTC-specific guidance removed from FASB ASC 323-740, Investments – Equity Method and Joint Ventures: Income Taxes, has been applied. ASU 2023-02 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for any interim period within those fiscal years. The amendments in ASU 2023-02 must be applied on either a modified retrospective or a retrospective basis (except as discussed in the ASU for LIHTC investments not accounted for using the proportional amortization method). The Company is currently evaluating the provisions of this ASU to determine the potential impact the new standard will have on the Company’s consolidated financial statements. Impact of recent authoritative accounting guidance — On January 1, 2023, the company adopted the FASB issued guidance within ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this ASU eliminate the current troubled debt restructuring (TDR) recognition and measurement guidance and, instead, require that a creditor evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments also introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. These amendments require vintage disclosures including current-period gross write-offs by year of origination for financing receivables. Gross write-off information must be included in the vintage disclosures in accordance with ASC 326-20-50-6, which requires disclosure of the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination.

Management measures expected credit losses on held-to-maturity securities on a collective basis by major security type with each type sharing similar risk characteristics, and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. With regard to residential mortgage-backed securities issued by the U.S. government, or agencies thereof, it is expected that the securities will not be settled at prices less than the amortized cost bases of the securities as such securities are backed by the full faith and credit of and/or guaranteed by the U.S. government. Accordingly, no allowance for credit losses has been recorded for these securities. With regard to securities issued by States and political subdivisions and other held-to-maturity securities, management considers (i) issuer bond ratings, (ii) historical loss rates for given bond ratings, (iii) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities, (iv) internal forecasts and (v) whether or not such securities are guaranteed or pre-refunded by the issuers. Fair values are based on quoted market prices or dealer quotes. If a quoted market price or dealer quote is not available, fair value is estimated using quoted market prices for similar securities. The following tables show the gross unrealized losses for available-for-sale securities, for which an allowance for credit losses has not been recorded, that are less than 12 months and 12 months or more: Available-for-Sale Securities March 31, 2023 Less Than 12 Months 12 Months or More Total (Dollars in thousands) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses As of March 31 2023 U.S. Government-sponsored securities $ 330 $ 1 $ 1,246 $ 22 $ 1,576 $ 23 Mortgage-backed securities (1) 12,450 343 86,844 21,611 99,294 21,954 Collateralized mortgage obligations (1) - - 607 13 607 13 Corporate securities - - 9,711 330 9,711 330 Total available-for-sale securities $ 12,780 $ 344 $ 98,408 $ 21,976 $ 111,188 $ 22,320 (1) All mortgage-backed securities and collateralized mortgage obligations Available-for-Sale Securities December 31, 2022 Less Than 12 Months 12 Months or More Total (Dollars in thousands) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses As of December 31, 2022 U.S. Treasury notes $ 4,964 $ 25 $ - $ - $ 4,964 $ 25 U.S. Government-sponsored securities 378 1 1,326 23 1,704 24 Mortgage-backed securities (1) 35,117 1,639 96,589 28,156 131,706 29,795 Collateralized Mortgage Obligations (1) 1,054 31 - - 1,054 31 Corporate securities - - 9,581 462 9,581 462 Total available-for-sale securities $ 41,513 $ 1,696 $ 107,496 $ 28,641 $ 149,009 $ 30,337 (1) All mortgage-backed securities and collateralized mortgage obligations As of March 31, 2023, the Company held 183 available-for-sale securities of which 61 were in an unrealized loss position for less than twelve months and 97 securities were in an unrealized loss position for twelve months or more without an allowance for credit losses. Because the decline in fair value is attributable to changes in interest rates and not credit quality and because the Company does not have the intent to sell these securities and it is more likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be impaired. Management evaluates the available-for-sale debt securities in an unrealized loss position, relying primarily on industry analyst reports and observations of market conditions and interest rate fluctuations. The following table presents the activity in the allowance for credit losses for held-to-maturity securities by major type: March 31, 2023 (Dollars in thousands) Municipal securities Mortgage- backed securities Collateralized Mortgage obligations Total Allowance for credit losses - securities Beginning Balance $ 393 $ - $ - $ 393 Provision for credit losses - - - - Ending Balance $ 393 $ - $ - $ 393 December 31, 2022 (Dollars in thousands) Municipal securities Mortgage- backed securities Collateralized Mortgage obligations Total Allowance for credit losses - securities Beginning Balance $ 393 $ - $ - $ 393 Provision for credit losses - - - - Ending Balance $ 393 $ - $ - $ 393 The amortized cost and estimated fair values of debt securities at March 31, 2023 by contractual final maturity are shown in the following table: Available-for-Sale Held-to-Maturity (Dollars in thousands) Amortized Cost Fair Value Amortized Cost Fair Value Securities maturing in: One year or less $ 335 $ 335 $ 283 $ 283 After one year through five years 19,386 18,756 11,174 11,155 After five years through ten years 6,114 5,913 30,348 28,835 After ten years 114,863 93,433 808,582 665,636 Total $ 140,698 $ 118,437 $ 850,387 $ 705,909 Maturities are based on the final contractual payment dates, and do not reflect the impact of prepayments or early redemptions that may occur. Expected maturities of mortgage-backed and CMO securities may differ from contractual maturities because borrowers have the right to call or prepay obligations with or without call or prepayment penalties. The Company monitors the credit quality of those held-to-maturity debt securities not issued by the U.S. government or one of its agencies or government sponsored entities, through the use of credit ratings. Credit ratings are reviewed and updated quarterly. The following table summarizes the amortized cost of held-to-maturity municipal debt securities by credit rating at March 31, 2023: Held-to-Maturity Amortized Cost (Dollars in thousands) AAA/AA/A BBB/BB/B Not Rated Total March 31, 2023 Municipal securities $ 19,380 $ 390 $ 56,490 $ 76,260 Total $ 19,380 $ 390 $ 56,490 $ 76,260 As of March 31, 2023, there were no past due principal or interest payments associated with these securities.

These related parties, including their immediate families and companies in which they are principal owners, were loan customers of the Bank during the three months ended March 31, 2023 and year ended December 31, 2022. Such loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with borrowers not related to the Company. These loans did not involve more than the normal risk of collection or have other unfavorable features. A summary of the changes in those loans is as follows: March 31, December 31, (Dollars in thousands) 2023 2022 Balance at beginning of the period $ 17,521 $ 18,128 New loans or advances during year 130 523 Repayments (372 ) (1,130 ) Balance at end of period $ 17,279 $ 17,521 A loan or lease is considered collateral dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. When management determines that foreclosure is probable, expected credit losses for collateral dependent loans or leases are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. The collateral on the loans and leases is a significant portion of what secures the collateral dependent loans or leases and significant changes to the fair value of the collateral can impact the ACL. During the three months ended March 31, 2023, there were no significant changes to the collateral that secures the collateral dependent loans, whether due to general deterioration or with credit quality indicators like appraisal value.

Employee Benefit Plans [Abstract]
Employee Benefit Plans	Note 7—Employee Benefit Plans Executive Retirement Plan The Company, through the Bank, sponsors an Executive Retirement Plan (“ERP”) for certain executive level employees. The ERP is a non-qualified deferred compensation plan and was developed to supplement the Company’s Profit Sharing Plan, which, as a qualified retirement plan, has a ceiling on benefits as set by Internal Revenue Service regulations. The ERP is comprised of: (1) a Performance Component which makes contributions based upon long-term cumulative profitability and increase in market value of the Company; (2) a Salary Component which makes contributions based upon participant salary levels; and (3) an Equity Component for which contributions are discretionary and subject to Board of Directors approval. The Company expensed $2.3 million to the ERP during the three months ended March 31, 2023 and $1.8 million during the three months ended March 31, 2022. The Company’s carrying value of the liability under the ERP was $55.1 million as of March 31, 2023 and $57.0 million as of December 31, 2022. The Company’s shares of common stock held as investments in the Rabbi Trust of the ERP as of March 31, 2023 and December 31, 2022 totaled 48,055 and 50,196 with an historical cost basis of $30.0 million and $31.4 million, respectively. All amounts have been fully funded into the Rabbi Trust as of March 31, 2023 and December 31, 2022. The consolidated investments held in the Rabbi Trust are recorded at fair value with changes in unrealized gains or losses recorded within non-interest income and the equal and offsetting charges in the related liability are recorded in non-interest expense in the consolidated statements of income. Net gains on ERP plan investments were $0.7 million compared to net gains of $0.3 million at March 31, 2023 and 2022, respectively. Balances in non-qualified deferred compensation plans may be invested in financial instruments whose market value fluctuates based upon trends in interest rates and stock prices. Senior Management Retention Plan The Company, through the Bank, sponsors a Senior Management Retention Plan (“SMRP”) for certain senior level employees. The SMRP is a non-qualified deferred compensation plan and was developed to supplement the Company’s Profit Sharing Plan, which, as a qualified retirement plan, has a ceiling on benefits as set by Internal Revenue Service regulations. All contributions are discretionary and subject to the Board of Directors approval. The Company expensed $1.2 million to the SMRP during the three months ended March 31, 2023 and $0.7 million for three months ended March 31, 2022. The Company’s carrying value of the liability under the SMRP was $15.4 million as of March 31, 2023 and $13.6 million as of December 31, 2022.

The consolidated investments held in the Rabbi Trust are recorded at fair value with changes in unrealized gains or losses recorded within non-interest income and the equal and offsetting charges in the related liability are recorded in non-interest expense in the consolidated statements of income. Net gains on SMRP plan investments were $0.2 million compared to net gains of $0.1 million at March 31, 2023 and 2022, respectively. Balances in non-qualified deferred compensation plans may be invested in financial instruments whose market value fluctuates based upon trends in interest rates and stock prices.

Fair Value [Abstract]
Fair Value	Note 8—Fair Value The Company follows the “Fair Value Measurement and Disclosures” topic of the FASB ASC Topic 820, which establishes a framework for measuring fair value in U.S. GAAP and expands disclosures about fair value measurements. This standard applies whenever other standards require, or permit assets or liabilities to be measured at fair value but does not expand the use of fair value in any new circumstances. In this standard, the FASB clarifies the principle that fair value should be based on the assumptions market participants would use when pricing the asset or liability. In support of this principle, this standard establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy is as follows Level 1 inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Level 2 inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. Management monitors the availability of observable market data to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. Management evaluates the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total assets, total liabilities or total earnings. Securities classified as available-for-sale are reported at fair value on a recurring basis utilizing Level 1, 2 and 3 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 dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s Collateral dependent loans represent certain loans held for investment that are subject to a fair value measurement under U.S. GAAP because they are individually evaluated using a fair value measurement, such as the fair value of the underlying collateral. Credit loss is measured using a market approach based on the fair value of the collateral, less estimated costs to dispose, for loans the Company considers to be collateral dependent. Collateral dependent loans and leases not requiring an allowance represent loans and leases for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans and leases. loans and leases where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. These appraisals may utilize a single valuation approach or a combination of approaches including sales comparison, cost and the income approach. Adjustments are often made in the appraisal process by the appraisers to take into account differences between the comparable sales and income and other available data. Such adjustments can be significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for Level 3 non-recurring collateral dependent loans and leases estimated Other Real Estate Owned (“OREO”) is reported at fair value on a non-recurring basis. Fair values are based on recent real estate appraisals. These appraisals may use a single valuation approach or a combination of approaches including sales comparison, cost and the income approach. Adjustments are often made in the appraisal process by the appraisers to take in to account differences between the comparable sales and income and other available data. Such adjustments can be significant and typically result in a Level 3 classification of the inputs for determining fair value. The valuation technique used for Level 3 non-recurring OREO is primarily the sales comparison approach less estimated The following tables summarize the carrying amount and estimated fair values of the Company’s financial assets and liabilities not carried at fair value, and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value for the periods indicated.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 9—Commitments and Contingencies In the normal course of business, the Company enters into financial instruments with off balance sheet risk in order to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These instruments include commitments to extend credit, letters of credit, and other types of financial guarantees. The Company had the following off balance sheet commitments as of the dates indicated. (Dollars in thousands) March 31, 2023 December 31, 2022 Commitments to extend credit, including unsecured commitments of $ 20,114 20,401 $ 1,174,664 $ 1,141,036 Stand-by letters of credit, including unsecured commitments of $ 8,059 7,954 16,821 17,138 The Company’s exposure to credit loss in the event of nonperformance by the other party with regard to standby letters of credit, undisbursed loan commitments, and financial guarantees is represented by the contractual notional amount of those instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. The Company uses the same credit policies in making commitments and conditional obligations as it does for recorded balance sheet items. The Company may or may not require collateral or other security to support financial instruments with credit risk. Evaluations of each customer’s creditworthiness are performed on a case-by-case basis. The estimated exposure to loss from these commitments is included in the reserve for unfunded loan commitments which amounted to $2.1 million at March 31, 2023 and December 31, 2022. Standby letters of credit are conditional commitments issued by the Company to guarantee performance of or payment for a customer to a third-party. Outstanding standby letters of credit have maturity dates ranging from 1 to 60 months with final expiration in January 2027. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The Company has commitments to fund investments in LIHTC partnerships and limited liability companies. At March 31, 2023, the remaining commitments to the LIHTC partnerships and limited liability companies were approximately $18.8 million. At December 31, 2022, the remaining commitments to the LIHTC partnerships and the limited liability companies were $19.7 million. In the ordinary course of business, the Company becomes involved in litigation arising out of its normal business activities. Management, after consultation with legal counsel, believes that the ultimate liability, if any, resulting from the disposition of such claims would not be material in relation to the financial position of the Company. The Company may be required to maintain average reserves on deposit with the Federal Reserve Bank primarily based on deposits outstanding. Reserve requirements are offset by the Company’s vault cash and deposit balances maintained with the Federal Reserve Bank.

Accounting Standards Adoption	Accounting Standards Pending Adoption — The following paragraphs provide descriptions of newly issued but not yet effective accounting standards that could have a material effect on the Company’s financial position or results of operations. In March 2020, the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) issued ASU . ASU 2020-04 was effective upon issuance and, based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. We have not elected to apply these amendments. However, we will assess the applicabil In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848). The main amendments in this ASU are intended to clarify certain optional expedients and scope of derivative instruments. The amendments are elective and effective immediately upon issuance of this ASU. ASU 2021-01 was effective upon issuance and, based upon the amendments provided in ASU 2022-06 discussed below, can generally be applied through December 31, 2024. We have not elected to apply amendments; however, will assess the applicability of this ASU to us as we continue to monitor guidance for reference rate reform from FASB and its impact on our financial condition and results of operations. ASU No. 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848.” ASU 2022-06 extends the period of time preparers can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06, which was effective upon issuance, defers the sunset date of this prior guidance from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. We have not elected to apply amendments at this time, however, will assess the applicability of this ASU to us as we continue to monitor guidance for reference rate reform from FASB and its impact on our financial condition and results of operations. In June 2022, the FASB issued guidance within ASU 2022-03, Fair Value Measurement of Equity Securities Subject to contractual Sale Restrictions. The amendments in this ASU affect all entities that have investments in equity securities measured at fair value that are subject to a contractual sale restriction. These amendments clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments in this ASU are effective for fiscal years, beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The adoption of this ASU is not expected to have material impact on the Company’s Consolidated Financial Statements In March 2023, the FASB issued ASU 2023-02, Investments – Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. ASU 2023-02 allows reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. The Amendments in ASU 2023-02 apply to all reporting entities that hold (1) tax equity investments that meet the conditions for and elect to account for them using the proportional amortization method or (2) an investment in a LIHTC structure through a limited liability entity that is not accounted for using the proportional amortization method and to which certain LIHTC-specific guidance removed from FASB ASC 323-740, Investments – Equity Method and Joint Ventures: Income Taxes, has been applied. ASU 2023-02 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted for any interim period within those fiscal years. The amendments in ASU 2023-02 must be applied on either a modified retrospective or a retrospective basis (except as discussed in the ASU for LIHTC investments not accounted for using the proportional amortization method). The Company is currently evaluating the provisions of this ASU to determine the potential impact the new standard will have on the Company’s consolidated financial statements. Impact of recent authoritative accounting guidance — On January 1, 2023, the company adopted the FASB issued guidance within ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this ASU eliminate the current troubled debt restructuring (TDR) recognition and measurement guidance and, instead, require that a creditor evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments also introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. These amendments require vintage disclosures including current-period gross write-offs by year of origination for financing receivables. Gross write-off information must be included in the vintage disclosures in accordance with ASC 326-20-50-6, which requires disclosure of the amortized cost basis of financing receivables by credit quality indicator and class of financing receivable by year of origination.
