Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash includes cash on hand, cash with correspondent banks, and cash on deposit at the Federal Reserve Bank of Richmond. Cash equivalents are short-term, highly liquid investments that are readily convertible to cash with original maturities of three months or less and are subject to an insignificant risk of change in value. Cash and cash equivalents are carried at cost.

Marketable Securities, Policy [Policy Text Block]

Securities

Certain debt securities that management has the positive intent and ability to hold to maturity are classified as "held to maturity" and recorded at amortized cost. Trading securities are recorded at fair value with changes in fair value included in earnings. Debt securities not classified as held to maturity or trading are classified as "available for sale" and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in other comprehensive income. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities or to the earliest call with premiums. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

The Company does not currently have any securities in held to maturity or trading and has no plans to add any to either category. Management evaluates securities for other-than-temporary impairment ("OTTI") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: (1) OTTI related to credit loss, which must be recognized in the income statement and, (2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis.

Equity securities with readily determinable fair values are carried at fair value with changes in fair value included in noninterest income.

Due to the nature and restrictions placed on the Company's investment in common stock of the Federal Home Loan Bank of Atlanta ("FHLB") and the Federal Reserve Bank of Richmond, these securities have been classified as restricted equity securities and carried at cost.

Loan Commitments, Policy [Policy Text Block]

Derivative Loan Commitments

The Company enters into mortgage loan commitments whereby the interest rate on the loan is determined prior to funding (rate lock commitments). Mortgage loan commitments are referred to as derivative loan commitments if the loan that will result from exercise of the commitment will be held for sale upon funding. Loan commitments that are derivatives are recognized at fair value on the consolidated balance sheets with net changes in their fair values recorded in other expenses.

The period of time between issuance of a loan commitment and sale of the loan generally ranges from 30 to 60 days. The Company protects itself from changes in interest rates through the use of best efforts forward delivery contracts, by committing to sell a loan at the time the borrower commits to an interest rate with the intent that the buyer has assumed the interest rate risk on the loan. As a result, the Company is not generally exposed to significant losses nor will it realize significant gains related to its rate lock commitments due to changes in interest rates. The correlation between the rate lock commitments and the best efforts contracts is very high due to their similarity.

The fair value of rate lock commitments and best efforts contracts is not readily ascertainable with precision because rate lock commitments and best efforts contracts are not actively traded in stand-alone markets. The Company determines the fair value of rate lock commitments and best efforts contracts by measuring the change in the estimated value of the underlying assets while taking into consideration the probability that the loans will be funded.

Troubled Debt Restructuring [Policy Text Block]

Troubled Debt Restructurings

In situations where, for economic or legal reasons related to a borrower's financial condition, management may grant a concession to the borrower that it would not otherwise consider, the related loan is classified as a TDR. Management strives to identify borrowers in financial difficulty early and work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal, management measures any impairment on the restructuring as noted above for impaired loans. The Company had $1,725,000 in loans classified as TDRs as of December 31, 2021 and $1,976,000 as of December 31, 2020.

Property, Plant and Equipment, Policy [Policy Text Block]

Premises and Equipment

Land is carried at cost. Premises and equipment are stated at cost, less accumulated depreciation and amortization. Premises and equipment are depreciated over their estimated useful lives ranging from three years to thirty-nine years; leasehold improvements are amortized over the lives of the respective leases or the estimated useful lives of the improvements, whichever is less. Software is generally amortized over three years. Depreciation and amortization are recorded on the straight-line method.

Costs of maintenance and repairs are charged to expense as incurred. Costs of replacing structural parts of major units are considered individually and are expensed or capitalized as the facts dictate. Gains and losses on routine dispositions are reflected in current operations.

Trust Assets [Policy Text Block]

Trust Assets

Securities and other property held by the trust and investment services segment in a fiduciary or agency capacity are not assets of the Company and are not included in the accompanying consolidated financial statements.

Life Insurance, Bank Owned [Policy Text Block]

Bank Owned Life Insurance

In connection with mergers, the Company has acquired bank owned life insurance ("BOLI"). The asset is reflected as the cash surrender value of the policies as provided by the insurer on a monthly basis.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company uses the balance sheet method to account for deferred income tax assets and liabilities. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the temporary differences between the book and tax bases of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws.

When tax returns are filed, it is highly certain that some positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is reflected as a liability for unrecognized tax benefits in the accompanying consolidated balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company had no liability for unrecognized tax benefits as of December 31, 2021 and 2020.

Earnings Per Share, Policy [Policy Text Block]

Earnings Per Common Share

Basic earnings per common share represent income available to common shareholders divided by the average number of common shares outstanding during the period. Diluted earnings per common share reflect the impact of additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company consist solely of outstanding stock options and are determined using the treasury method. Nonvested shares of restricted stock are included in the computation of basic earnings per share because the holder has voting rights and shares in non-forfeitable dividends during the vesting period.

Advertising Cost [Policy Text Block]

Advertising and Marketing Costs

Advertising and marketing costs are expensed as incurred, and were $506,000, $453,000, and $473,000 in 2021, 2020, and 2019, respectively.

Derivatives, Policy [Policy Text Block]

Derivative Financial Instruments

The Company uses derivatives primarily to manage risk associated with changing interest rates. The Company's derivative financial instruments consist of interest rate swaps that qualify as cash flow hedges of the Company's trust preferred capital notes. The Company recognizes derivative financial instruments at fair value as either an other asset or other liability in the consolidated balance sheets. The effective portion of the gain or loss on the Company's cash flow hedges is reported as a component of other comprehensive income, net of deferred income taxes, and is reclassified into earnings in the same period or periods during which the hedged transactions affect earnings.

New Accounting Pronouncements, Policy [Policy Text Block]

Recently Adopted Accounting Developments

In January 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." ASU 2017-04 simplifies the accounting for goodwill impairment for all entities by requiring impairment charges to be based on the first step in the previous two-step impairment test. Under the new guidance, if a reporting unit's carrying amount exceeds its fair value, an entity will record an impairment charge based on that difference. The impairment charge will be limited to the amount of goodwill allocated to that reporting unit. The standard eliminates the prior requirement to calculate a goodwill impairment charge using Step 2, which requires an entity to calculate any impairment charge by comparing the implied fair value of goodwill with its carrying amount. ASU 2017-04 was effective for the Company on January 1, 2021. The adoption of ASU 2017-04 did not have a material effect on the Company's consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes." The ASU is expected to reduce cost and complexity related to the accounting for income taxes by removing specific exceptions to general principles in Topic 740 (eliminating the need for an organization to analyze whether certain exceptions apply in a given period) and improving financial statement preparers' application of certain income tax-related guidance. This ASU is part of the FASB's simplification initiative to make narrow-scope simplifications and improvements to accounting standards through a series of short-term projects. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. The adoption of ASU 2019-12 did not have a material effect on the Company's consolidated financial statements.

In January 2020, the FASB issued ASU 2020-01, "Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." The ASU is based on a consensus of the Emerging Issues Task Force and is expected to increase comparability in accounting for these transactions. ASU 2020-01 made targeted improvements to accounting for financial instruments, including providing an entity the ability to measure certain equity securities without a readily determinable fair value at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Among other topics, the amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting. For public business entities, such as the Company, the amendments in the ASU are effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The adoption of ASU 2020-01 did not have a material effect on the Company's consolidated financial statements.

In October 2020, the FASB issued ASU 2020-08, "Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable fees and Other Costs." This ASU clarifies that an entity should reevaluate whether a callable debt security is within the scope of ASC paragraph 310-20-35-33 for each reporting period. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The adoption of ASU 2020-08 did not have a material effect on the Company's consolidated financial statements.

In December 2020, the Consolidated Appropriations Act of 2021 ("Appropriations Act") was passed. Under Section 541 of the Appropriations Act, Congress extended or modified many of the relief programs first created by the Coronavirus Aid, Relief, and Economic Security Act ('CARES Act"), including the Paycheck Protection Program ("PPP") and treatment of certain loan modifications related to the COVID-19 pandemic. The Act did not have a material effect on the Company's consolidated financial statements. The aggregate loan balances for the PPP at December 31, 2021 and 2020, respectively, were $12.2 million and $211.3 million. Loan modification balances outstanding at December 31, 2020 were $30.0 million and all remaining modifications expired during 2021 and all loans resumed making normal payments.

Recent Accounting Pronouncements and Other Authoritative Accounting Guidance

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The FASB has issued multiple updates to ASU 2016-13 as codified in Topic 326, including ASU's 2019-04, 2019-05, 2019-10, 2019-11, 2020-02, and 2020-03. These ASUs have provided for various minor technical corrections and improvements to the codification as well as other transition matters. Smaller reporting companies who file with the U.S. Securities and Exchange Commission ("SEC") and all other entities who do not file with the SEC are required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022. At the one-time evaluation date, the Company qualified as a smaller reporting company and elected to defer the adoption of the standard. The Company began running parallel simulations with its historical loss model starting in the fourth quarter of 2021 and will continue this practice until adoption on January 1, 2023. The Company is working to ensure readiness and compliance with the standard. The Company has engaged with a vendor, validated data, analyzed correlations for forecasting, selected methodologies and begun running parallel models. Management will continue to refine assumptions that impact the calculation prior to the effective date.

Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin ("SAB") 119. SAB 119 updated portions of SEC interpretative guidance to align with ASC 326, "Financial Instruments - Credit Losses." It covers topics including (1) measuring current expected credit losses; (2) development, governance, and documentation of a systematic methodology; (3) documenting the results of a systematic methodology; and (4) validating a systematic methodology.

In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The amendments in this ASU provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. Subsequently, in January 2021, the FASB issued ASU 2021-01 "Reference Rate Reform (Topic 848): Scope." This ASU clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The ASU also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. An entity may elect to apply ASU 2021-01 on contract modifications that change the interest rate used for margining, discounting, or contract price alignment retrospectively as of any date from the beginning of the interim period that includes March 12, 2020, or prospectively to new modifications from any date within the interim period that includes or is subsequent to January 7, 2021, up to the date that financial statements are available to be issued. An entity may elect to apply ASU 2021-01 to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020, and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. The Company does not expect the adoption of ASU 2020-04 to have a material impact on its consolidated financial statements.

In August 2020, the FASB issued ASU 2020-06, "Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity." The ASU simplifies accounting for convertible instruments by removing major separation models required under current GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument and more convertible preferred stock as a single equity instrument with no separate accounting for embedded conversion features. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. The ASU also simplifies the diluted earnings per share calculation in certain areas. In addition, the amendment updates the disclosure requirements for convertible instruments to increase the information transparency. For public business entities, excluding smaller reporting companies, the amendments in the ASU are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. For all other entities, the standard will be effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the adoption of ASU 2020-06 to have a material impact on its consolidated financial statements.

In May 2021, the FASB issued ASU 2021-04, "Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Subtopic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer's Accounting for Certain Modifications or Exchanges of Freestanding Equity – Classified Written Call Options (a consensus of the FASB Emerging Issues Task Force)." The ASU addresses how an issuer should account for modifications or an exchange of freestanding written call options classified as equity that is not within the scope of another Topic. For both public and private companies, the ASU is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Transition is prospective. Early adoption is permitted. The Company does not expect the adoption of ASU 2021-04 to have a material impact on its consolidated financial statements.

In August 2021, the FASB issued ASU 2021-06, "Presentation of Financial Statements (Topic 205), Financial Services—Depository and Lending (Topic 942), and Financial Services—Investment Companies (Topic 946): Amendments to SEC Paragraphs Pursuant to SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants." This ASU incorporates recent SEC rule changes into the FASB Codification, including SEC Final Rule Releases No. 33-10786, Amendments to Financial Disclosures about Acquired and Disposed Businesses, and No. 33-10835, Update of Statistical Disclosures for Bank and Savings and Loan Registrants. The ASU is effective upon addition to the FASB Codification. The Company does not expect the adoption of ASU 2021-06 to have a material impact on its consolidated financial statements

In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." The ASU requires entities to apply Topic 606 to recognize and measure contract assets and contract liabilities in a business combination. The amendments improve comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. The ASU is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2022. Entities should apply the amendments prospectively and early adoption is permitted. The Company does not expect the adoption of ASU 2021-08 to have a material impact on its consolidated financial statements.
