Notes to Financial Statements
Basis of Presentation and Significant Accounting Policies [Text Block]	Note 1. Basis of Presentation *General* First Community Bankshares, Inc. (the “Company”), is a financial holding company incorporated under the laws of the Commonwealth of Virginia. The Company’s principal executive office is located in Bluefield, Virginia. The Company provides banking products and services to individual and commercial customers through its wholly owned subsidiary First Community Bank (the “Bank”), a Virginia-chartered banking institution founded in 1874. The Bank offers wealth management and investment advice through its Trust Division and wholly owned subsidiary First Community Wealth Management, Inc. (“FCWM”). Unless the context suggests otherwise, the terms “First Community,” “Company,” “we,” “our,” and “us” refer to First Community Bankshares, Inc. and its subsidiaries as a consolidated entity. *Principles of Consolidation* The Company’s accounting and reporting policies conform with U.S. generally accepted accounting principles (“GAAP”) and prevailing practices in the banking industry. The consolidated financial statements include all accounts of the Company and its wholly owned subsidiaries and eliminate all intercompany balances and transactions. The Company operates in one business segment, Community Banking, which consists of all operations, including commercial and consumer banking, lending activities, and wealth management. Operating results for interim periods are not necessarily indicative of results that may be expected for other interim periods or for the full year. In management’s opinion, the accompanying unaudited interim condensed consolidated financial statements contain all necessary adjustments, including normal recurring accruals, and disclosures for a fair presentation. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Form 10-K”), as filed with the Securities and Exchange Commission (the “SEC”) on February 22, 2023. The condensed consolidated balance sheet as of December 31, 2022, has been derived from the audited consolidated financial statements. *Reclassifications* Certain amounts reported in prior years have been reclassified to conform to the current year’s presentation. These reclassifications had no effect on the Company’s results of operations, financial position, or net cash flow. *Use of Estimates* Preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that require the most subjective or complex judgments relate to fair value measurements, the allowance for credit losses, goodwill and other intangible assets, and income taxes. A discussion of the Company’s application of critical accounting estimates is included in “Critical Accounting Estimates” in Item 2 of this report. *Significant Accounting Policies* The Company’s significant accounting policies are included in Note 1, “Basis of Presentation and Significant Accounting Policies,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of the Company’s 2022 Form 10-K. *Allowance for Credit Losses (“ACL”) On January 1,* 2021, the Company adopted ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” This ASU applies to all financial assets measured at amortized cost and off balance sheet credit exposures, including loans, investment securities, and unfunded commitments. ACL – Investment Securities Each quarter, the Company evaluates impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value. The nature of the collateral is considered along with potential future changes in collateral values, default rates, delinquency rates, third-party guarantees, credit ratings, interest rate changes since purchase, volatility of the security’s fair value and historical loss information for financial assets secured with similar collateral among other factors. Credit losses are calculated individually, rather than collectively, using a discounted cash flow method, whereby management compares the present value of expected cash flows with the amortized cost basis of the security. The credit loss component would be recognized through the provision for credit losses in the Statement of Income and establish an allowance for credit losses on the Balance Sheet. The Company excludes the accrued interest receivable from the amortized cost basis in measuring expected credit losses on the investment securities and does not record an allowance for credit losses on accrued interest receivable. As of September 30, 2023, the accrued interest receivable for investment securities available for sale was $1.07 million. The Company’s estimate of expected credit losses includes a measure of the expected risk of credit loss even if that risk is remote. The Company does not measure expected credit losses on an investment security in which historical credit loss information adjusted for current conditions and reasonable and supportable forecast results in an expectation that nonpayment of the amortized cost basis is zero. Nonpayment of the amortized cost basis is not expected to be zero solely on the basis of the current value of collateral securing the security but, also considers the nature of the collateral, potential future changes in collateral values, default rates, delinquency rates, third-party guarantees, credit ratings, interest rate change since purchase, volatility of the security’s fair value and historical loss information for financial assets securitized with similar collateral. The Company performed an analysis that determined that the following securities have a zero expected credit loss: U.S. Treasury Securities, Agency-Backed Securities including Government National Mortgage Association (“GNMA”), Federal Home Loan Mortgage Corporation (“FHLMC”), Federal National Mortgage Association (“FNMA”), Federal Home Loan Bank (“FHLB”), Federal Farm Credit Banks (“FFCB”) and Small Business Administration (“SBA”). All of the U.S. Treasury and Agency-Backed Securities have the full faith and credit backing of the United States Government or one of its agencies. These securities are included in Government-Sponsored Entities Debt and Mortgage-Backed Securities line items in the Investment Securities footnote. Municipal securities and all other securities that do not have a zero expected credit loss will be evaluated quarterly to determine whether there is a credit loss associated with a decline in fair value. ACL – Loans The Company reviews our allowance for credit losses quarterly to determine if it is sufficient to absorb expected loan losses in the portfolio. This determination requires management to make significant estimates and assumptions. While the Company uses its best judgment and available information, the ultimate adequacy of the allowance is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates, and the view of regulatory authorities towards loan classifications. These uncertainties may result in material changes to the allowance for credit losses in the near term; however, the amount of the change cannot reasonably be estimated. The ACL is an estimate of losses that will result from the inability of borrowers to make required loan payments. The Company established the incremental increase in the ACL at the adoption through retained earnings and subsequent adjustments will be made through a provision for credit losses charged to earnings. Loans charged off are recorded against the ACL and subsequent recoveries increase the ACL when they are recognized. A systematic methodology is used to determine ACL for loans held for investment and certain off-balance sheet credit exposures. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loan portfolio. The Company considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The Company’s estimate of its ACL involves a high degree of judgement and reflects management’s best estimate within the range of expected credit losses. The Company recognizes in net income the amount needed to adjust the ACL for management’s current estimate of expected credit losses. The Company’s ACL is calculated using collectively evaluated and individually evaluated loans. The Company collectively evaluates loans that share similar risk characteristics. In general, loans are segmented by loan purpose. The Company collectively evaluates loans within the following consumer and commercial segments: Loans secured by 1-4 Family Properties, Home Equity Lines of Credit (“HELOC”), Owner Occupied Construction Loans, Consumer Loans, Commercial and Industrial, Multi-family, Non-farm/Non-residential Property, Commercial Construction/A&D/other Land Loans, Agricultural Loans, Credit Card Loans, Loans Secured by Farmland, and Other Consumer Loans (Overdrafts). Risk characteristics of residential real estate loans which include loans secured by Single family properties, HELOC, and Owner occupied construction loans are dependent upon individual borrowers who are affected by changes in general economic conditions, real estate valuations, and the demand for housing. Commercial and Industrial, Multi-family residential, Non-farm/non-residential, Agricultural, and Loans secured by Farmland are similar in that they are generally dependent upon the borrower's internal cash flow from operations to service the debt and changes in general economic conditions. Commercial construction, Development, and other land loans, Consumer, and Other consumer loans (open pool) are similar in that they are dependent on changes in general economic conditions. For collectively evaluated loans, the Company uses a combination of discounted cash flow and remaining life to estimate expected credit losses. During 2022, the Company changed third party model providers which necessitated a change from remaining life to open pool for the portfolios noted above. The change in method was not quantitatively significant. In addition to its own loss experience, management also includes peer bank historical loss experience in its assessment of expected credit losses to determine the ACL. The Company utilized call report data to measure its and its peers' historical credit losses experience with similar risk characteristics within the segments over an economic cycle. The Company reviewed the historical loss information to appropriately adjust for differences in current asset specific risk characteristics. Also considered were further adjustments to historical loss information for current conditions and reasonable and supportable forecasts that differ from the conditions that existed for the period over which historical information was evaluated. For the majority of the segments of collectively evaluated loans, the Company incorporated at least one macroeconomic driver using a statistical regression modeling methodology. The Company considers forward-looking information in estimated expected credit losses. The Company subscribes to a third-party service which provides summary detail of dozens of economic forecasts. Using that information and other publicly available economic forecasts, management determines the economic variables to use for the one-year reasonable and supportable forecast period. Management has determined that the forecast period is consistent with how the Company has historically forecasted for its profitability planning and capital management. Management has evaluated the appropriateness of the reasonable and supportable forecast for the current period along with the inputs used in the estimation of expected credit losses. For the contractual term that extends beyond the reasonable and supportable forecast period, the Company reverts to historical loss information over eight quarters using a straight-line approach. Management may apply different reversion techniques depending on the economic environment for the financial asset portfolio and as of the current period has utilized a linear reversion technique. Included in its systematic methodology to determine its ACL for loans held for investment and certain off-balance sheet credit exposures, The Company considers the need to qualitatively adjust expected credit losses for information not already captured in the loss estimation process. These qualitative adjustments either increase or decrease the quantitative model estimation. Each period the Company considers qualitative factors that are relevant within the qualitative framework that includes the following: 1) changes in lending policies and procedures, 2) changes in economic conditions, 3) changes in portfolio nature and volume, 4) changes in management, 5) changes in past due loans, 6) changes in the quality of the Company’s credit review system, 7) changes in the value of underlying collateral, 8) the effect of concentrations of credit, and 9) the effect of other external factors. When a loan no longer shares similar risk characteristics with its segment, the asset is assessed to determine whether it should be included in another pool or should be individually evaluated. The Company currently maintains a net book balance threshold of $500,000 for individually-evaluated loans. Generally, individually-evaluated loans are on nonaccrual status. Based on the threshold above, consumer loans will generally remain in pools unless they meet the dollar threshold and foreclosure is probable. The expected credit losses on individually-evaluated loans will be estimated based on discounted cash flow analysis unless the loan meets the criteria for use of the fair value of collateral, either by virtue of an expected foreclosure or through meeting the definition of collateral-dependent. Financial assets that have been individually evaluated can be returned to a pool for purposes of estimating the expected credit loss insofar as their credit profile improves and that the repayment terms were not considered to be unique to the asset. When loans are acquired they are identified as either purchased credit deteriorated ("PCD") or non-PCD. PCD loans represent assets that are acquired with evidence of more than insignificant credit quality deterioration since the origination of the loans as of the acquisition date. The ACL for PCD assets is recognized within business combination accounting with no initial impact to net income. Changes in estimates of expected credit losses on PCD loans after acquisition are recognized as provision expense (or reversal of provision expense) in subsequent periods as they arise. Non-PCD loans acquired are generally estimated at fair value using a discounted cash flow approach with assumptions of discount rate, remaining life, prepayments, probability of default, and loss given default. The actual cash flows on these loans could differ materially from the fair value estimates. The amount we record as the fair values for the loans is generally less than the contractual unpaid principal balance due from the borrowers, with the difference being referred to as the “discount” on the acquired loans. Discounts on acquired non-PCD loans are accreted to interest income over their estimated remaining lives, which may include prepayment estimates in certain circumstances. The ACL for non-PCD assets is recognized as provision expense in the same reporting period as the business combination. Estimated loan losses for acquired loans are determined using methodologies and applying estimates and assumptions similar to originated performing loans. The Company follows its nonaccrual policy by reversing contractual interest income in the income statement when the Company places a loan on nonaccrual status. Therefore, Management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the portfolio and does not record an allowance for credit losses on accrued interest receivable. As of September 30, 2023, the accrued interest receivable for loans was $9.35 million. Effective January 1, 2023, the Company adopted Financial Accounting Standards Board issued ASU 2022-02, Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures. As noted, the allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon origination. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. The Company uses a probability of default/loss given default model to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made at the time of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses, a change to the allowance for credit losses is generally not recorded upon modification. Occasionally, the Company modifies loans by providing principal forgiveness that is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. Additionally, the Company may allow a loan to go interest only for a specified period of time. The Company has a variety of assets that have a component that qualifies as an off-balance sheet exposure. These primarily include undrawn portions of revolving lines of credit and standby letters of credit. The estimates are determined based on the likelihood of funding during the contractual term and an estimate of credit losses subsequent to funding. Estimated credit losses on subsequently funded balances are based on the same assumptions as used to estimate credit losses on existing funded loans. The expected losses associated with these exposures within the unfunded portion of the loans will be recorded as a liability on the balance sheet with an offsetting income statement expense. Management has determined that a majority of the Company’s off-balance-sheet credit exposures are not unconditionally cancellable. As of September 30, 2023, the liability recorded for expected credit losses on unfunded commitments in Other Liabilities was $758 thousand. *Recent Accounting* *Standards* Standards Adopted in 2023 In March 2022, the Financial Accounting Standards Board issued ASU 2022-02, Financial Instruments-Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures. This new accounting topic provided accounting guidance for troubled debt restructuring (TDR) and write-offs, effective January 1, 2023. The amendments eliminated TDR accounting guidance for issuers that adopted ASU 2016-13, created a single loan modification accounting model, and clarified disclosure requirements for loan modifications and write-offs. We adopted this standard, effective January 1, 2023. The updated guidance had no material impact on our Consolidated Financial Statements. The Company does not expect other recent accounting standards issued by the FASB or other standards-setting bodies to have a material impact on the consolidated financial statements.
