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 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 California (“F&M Bank” or the “Bank”) (collectively, the “Company”).

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 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 determination of the provision and allowance for credit losses; (ii) the valuation of financial assets and liabilities recorded at fair value; (iii) the valuation of intangibles, such as goodwill and core deposit intangibles (“CDI”); (iv) the valuation of other real estate owned (“OREO”); and (v) 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 Unaudited Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates, in our Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 14, 2025 (“2024 Form 10-K”) and Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations - 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 2024 Form 10-K. Interim results are not necessarily indicative of results for a full year or any other interim period.

Summary of Significant Accounting Policies

Our accounting policies are described in Note 1 – Summary of Significant Accounting Policies, of our audited consolidated financial statements included in our 2024 Form 10-K.  As of September 30, 2025, there were no significant changes to accounting policies from those disclosed in our audited consolidated financial statements included in our 2024 Form 10-K.

Use of estimates — The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions.  These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates.

Recently Adopted Accounting Standards — The Accounting Standards Codification (“ASC”) is the FASB officially recognized source of authoritative GAAP applicable to all public and non-public non-governmental entities. Periodically, the FASB will issue Accounting Standard Updates (“ASU”) to its ASC. Rules and interpretive releases of the SEC under the authority of the federal securities laws are also sources of authoritative GAAP for the Company as an SEC registrant. All other accounting literature is non-authoritative.

In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” ASU 2023-09 requires public business entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if items meet a quantitative threshold. ASU 2023-09 also requires all entities to disclose income taxes paid, net of refunds, disaggregated by federal, state and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold, among other things. On January 1, 2025, the Company adopted this standard with no material impact on the Company’s consolidated financial statements, and the new income tax disclosures will be required beginning with our 2025 Form 10-K.

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 November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” (“ASU 2024-03”), and in January 2025, the FASB issued ASU No. 2025-01, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date” (“ASU 2025-01”). ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for public business entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Both early adoption and retrospective application are permitted. The Company is currently evaluating the impact that the adoption of these standards will have on its consolidated financial statements and disclosures.

In March 2025, the FASB issued ASU No. 2025-02, “Liabilities (Topic 405)-Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 122” (“ASU 2025-02”), which communicates changes to the FASB codification, including changes to non-authoritative SEC content. The update affects SEC registrants, makes amendments to the GAAP taxonomy and is effective upon issuance. Management has evaluated the impact of the adoption of this standard and determined there would be no material impact to the Company’s consolidated financial position or results of operations.

In July 2025, the FASB issued ASU No. 2025-05, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets” (“ASU 2025-05”). This ASU provides amendments that provide all entities with a practical expedient when estimating expected credit losses for current accounts receivable and current contract assets arising from transactions accounted for under Topic 606. The amendments are effective in fiscal years beginning after December 15, 2025, and interim reporting periods within those fiscal years. The Company is evaluating adoption timing and the impact ASU 2025-05 will have on its financial statements and, at this time, does not anticipate it will have a material impact on its consolidated financial statements.
