Notes to Financial Statements
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	Note 1. General The accompanying unaudited consolidated financial statements of First National Corporation (the Company) and its subsidiary, First Bank (the Bank), have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP. All significant intercompany balances and transactions have been eliminated. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments and reclassifications of a normal and recurring nature considered necessary to present fairly the financial positions at September 30, 2021 and December 31, 2020, the statements of income and comprehensive income for the three and nine months ended September 30, 2021 and 2020, the cash flows for the three and nine months ended September 30, 2021 and 2020, and the changes in shareholders’ equity for the three and nine months ended September 30, 2021 and 2020. The statements should be read in conjunction with the consolidated financial statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2020. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. Risks and Uncertainties The outbreak of COVID-19 has adversely impacted a broad range of industries in which the Company’s customers operate and could impair their ability to fulfill their financial obligations to the Company. The spread of the outbreak has caused disruptions in the U.S. economy. While there has been no material impact to the Company’s employees to date, COVID-19 could also potentially create widespread business continuity issues for the Company. Congress, the President, and the Federal Reserve have taken several actions designed to cushion the economic fallout. Most notably, the Coronavirus Aid, Relief and Economic Security (CARES) Act was signed into law in March 2020 as a $2 trillion legislative package and the American Rescue Plan Act of 2021 was signed into law in March 2021 and provides an additional $1.9 trillion in spending to address the continued impact of COVID-19. The goal of these legislative measures is to prevent a severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and providers. In addition to the general impact of COVID-19, certain provisions of the CARES Act as well as other recent legislative and regulatory relief efforts may have a material impact on the Company’s operations. The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 escalates further or is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. While it is not possible to know the full universe or extent that the impact of COVID-19, and resulting measures to curtail its spread, will have on the Company’s operations, the Company is disclosing potentially material items of which it is aware. Results of Operations The Company’s net interest income could decrease due to COVID-19. In keeping with guidance from regulators, the Company worked with certain COVID-19 affected borrowers to reduce their loan payments by modifying the loan agreements to allow for interest only payments. The loan modification periods ranged from 6 months to 24 months and were intended to provide payment relief to borrowers over the period of time that COVID-19 is expected to continue to negatively affect the profitability of the borrowers’ businesses. Although the modified loan payments have been made as agreed and interest income has been recognized by the Company, should the borrowers be negatively affected by COVID-19 for a period of time that extends beyond the loan modification periods, it’s possible the borrowers may not be able to resume regular principal and interest payments in future periods and the Company may no longer be able to accrue interest income on the loans. The Company’s net interest income could also decrease due to adverse economic conditions that may result from COVID-19 and a related decrease in loan demand, causing a shift in earning asset balances from loans into lower yielding interest-bearing deposits in banks and securities. The decrease in loan demand could also increase the competition for loans and result in a reduction of loan rates offered by other financial institutions. The Company's noninterest income could decrease due to COVID-19. Service charges on deposits decreased after the pandemic was declared and may decrease again in future periods. Wealth management revenue may decrease in future periods if the market values of investments decline and mortgage fee income may decrease from less home buying and refinancing activity in the Company's market area. At this time, the Company is unable to project the materiality of such an impact but recognizes it may unfavorably affect its noninterest income in future periods. The Company’s noninterest expense could increase due to COVID-19. If the Bank's asset quality worsens, it may incur additional loan expenses in future periods from obtaining updated appraisals on loan collateral, additional legal and professional expenses related to the resolution of problem loans, an increase in other real estate owned expense, and potential losses on the sale of other real estate owned. At this time, the Company is unable to project the full extent or materiality of the foregoing impacts but recognizes the breadth of the economic impacts of COVID-19 may have an unfavorable impact on net interest income, noninterest income, noninterest expense, and loan customers' ability to repay loans, in future periods. Capital and Liquidity While the Company believes it has sufficient capital to withstand an extended economic recession brought about by COVID-19, its reported and regulatory capital ratios could be adversely impacted by provision for loan losses in future periods. Larger amounts of provision for loan losses may result from factors including higher specific reserves on newly identified and existing impaired loans, higher levels of net charge-offs, and additional adjustments to qualitative factors in the general reserve component of the Bank’s allowance for loan losses. In March 2020, the Company suspended future stock repurchases under its stock repurchase program due to the economic uncertainty caused by the pandemic, and the program remained suspended for the remainder of 2020. The Company has not authorized another stock repurchase program due to the continued uncertainty and potential impact of the pandemic on the economy and the Bank’s customers. In June 2020, the Company issued $5.0 million of subordinated debt to strengthen holding company liquidity and to remain a source of strength to the Bank in the event of a severe economic downturn resulting from the pandemic. The Company will continue to update its enterprise risk assessment and capital plans as the operating environment develops. The Company maintains access to multiple sources of liquidity. While wholesale funding markets have remained open, interest rates for short term funding could become volatile. If funding costs would become elevated for an extended period of time, it may have an adverse effect on the Company’s net interest margin. If an extended recession causes large numbers of the Company’s deposit customers to withdraw their funds, the Company could become more reliant on volatile or more expensive sources of funding. Processes, Controls and Business Continuity Plan The Company continues to operate under its Pandemic Continuity of Operations Plan that includes a remote working strategy. The Company has not incurred additional material costs related to employees working remotely. No material operational or internal control challenges or risks have been identified to date. The Company does not anticipate significant challenges to its ability to maintain its systems and controls in light of the measures the Company has taken to prevent the spread of COVID-19. The Company does not currently face any material resource constraint through the implementation of its business continuity plan. Lending Operations and Accommodations to Borrowers In keeping with regulatory guidance to work with borrowers during this unprecedented situation, the Company offered a payment deferral program, primarily during the second and third quarters of 2020, for its individual and business customers adversely affected by the pandemic that deferred loan payments for up to 90 days. There were no loans remaining in the program at September 30, 2021. In accordance with the CARES Act and interagency guidance issued in August 2020, these short-term loan payment deferrals were not considered troubled debt restructurings. During the fourth quarter of 2020, and during the first half of 2021, the Bank modified terms of certain loans for customers that continued to be negatively impacted by the pandemic. The loan modifications lowered borrower loan payments by allowing interest only payments for periods ranging between 6 and 24 months. All loans modified were in the Bank’s commercial real estate loan portfolio and totaled $13.3 million at September 30, 2021, with $13.2 million in the Bank’s commercial real estate loan portfolio and $83 thousand in the commercial and industrial loans portfolio. The loans were comprised of $11.6 million in the lodging sector and $1.7 million in the leisure sector. The Bank actively participated as a lender in the U.S. Small Business Administration’s (“SBA”) Paycheck Protection Program (“PPP”) to support local small businesses and non-profit organizations by providing forgivable loans. Loan fees received from the SBA are accreted by the Bank into income evenly over the life of the loans, net of loan origination costs, through interest and fees on loans. PPP loans totaled $22.8 million at September 30, 2021, with $1.3 million scheduled to mature in the second and third quarters of 2022, and $21.5 million scheduled to mature in the first and second quarters of 2026. The Company believes the majority of these loans will ultimately be forgiven and repaid by the SBA in accordance with the terms of the program. It is the Company’s understanding that loans funded through the PPP program are fully guaranteed by the U.S. government. Should those circumstances change, the Company could be required to establish additional allowance for loan losses through additional provision for loan losses charged to earnings. The Bank recognized $737 thousand and $247 thousand of accretion on deferred PPP income, net origination costs, through interest and fees on loans for three month periods ending September 30, 2021 and 2020, respectively, and recognized $1.8 million and $429 thousand for the nine months ended September 30, 2021 and 2020, respectively. The total amount of deferred PPP income, net of origination costs, not yet been recognized through interest and fees on loans totaled $652 thousand at September 30, 2021. Asset Quality The economic impact of the pandemic had an unfavorable impact on the financial condition of certain Bank customers. The Bank entered into loan modification agreements in the fourth quarter of 2020, and during the first half of 2021, to provide relief to certain customers that were continuing to experience temporary business interruptions from the pandemic. The modifications were designed to help borrowers continue their business operations while minimizing potential loan charge-offs. The magnitude of the potential decline in the Bank’s loan quality will likely depend on the length and extent that the Bank’s customers experience business interruptions from the pandemic. Business Combinations On July 1, 2021, the Company completed the acquisition of The Bank of Fincastle (Fincastle) for an aggregate purchase price of $33.8 million of cash and stock. On September 30, 2021, the Bank acquired $82.0 million of loans and certain fixed assets from SmartBank related to their Richmond area branch. The Bank purchased the fixed assets for an amount equal to SmartBank’s book value. Additional information about these acquisitions is presented in Note 17. Adoption of New Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12, “Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes” (ASU 2019-12). 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. ASU 2019-12 was effective for the Company on January 1, 2021. The adoption of this standard did not have a material effect on the Company's consolidated financial statements. In January 2020, the FASB issued ASU No. 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” (ASU 2020-01). 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 2016-01 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. ASU 2020-01 was effective for the Company on January 1, 2021. The adoption of this standard did not have a material effect on the Company's consolidated financial statements. In October 2020, the FASB issued ASU No. 2020-08, “Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable fees and Other Costs” (ASU 2020-08). 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. ASU 2020-08 was effective for the Company on January 1, 2021. The adoption of this standard did not have a material effect on the Company's consolidated financial statements. In December 2020, the Consolidated Appropriations Act of 2021 (CAA) was passed. Under Section 541 of the CAA, Congress extended or modified many of the relief programs first created by the CARES Act, including the PPP loan program and treatment of certain loan modifications related to the COVID-19 pandemic. For information about the impact of the COVID-19 pandemic on the Company, see "Risks and Uncertainties" above. Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). 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 ASU’s 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), such as the Company, 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. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. The Company has formed a committee to address the compliance requirements of this ASU, which has analyzed gathered data, defined loan pools and segments, and selected methods for applying the concepts included in this ASU. The Company is in the process of testing selected models, building policy and processing documentation, modeling the impact of the ASU on the capital and strategic plans, performing model validation, and finalizing policies and procedures. This guidance may result in material changes in the Company's accounting for credit losses of financial instruments. Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin (SAB) 119. SAB 119 updated portions of SEC interpretative guidance to align with FASB 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 No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04). These amendments 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 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 No. 2021-01 “Reference Rate Reform (Topic 848): Scope” (ASU 2021-01). 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 is currently in the process of identifying loans and other financial instruments that are directly or indirectly influenced by LIBOR. The Company is assessing ASU 2020-04 and its impact on the Company's transition away from LIBOR for its loan and other financial instruments. In August 2020, the FASB issued ASU No. 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" (ASU 2020-06). The ASU simplifies accounting for convertible instruments by removing major separation models required under current U.S. 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 (EPS) 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.

Note 1. General

The accompanying unaudited consolidated financial statements of First National Corporation (the Company) and its subsidiary, First Bank (the Bank), have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP. All significant intercompany balances and transactions have been eliminated. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments and reclassifications of a normal and recurring nature considered necessary to present fairly the financial positions at September 30, 2021 and December 31, 2020, the statements of income and comprehensive income for the three and nine months ended September 30, 2021 and 2020, the cash flows for the three and nine months ended September 30, 2021 and 2020, and the changes in shareholders’ equity for the three and nine months ended September 30, 2021 and 2020. The statements should be read in conjunction with the consolidated financial statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2020. Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

Risks and Uncertainties

The outbreak of COVID-19 has adversely impacted a broad range of industries in which the Company’s customers operate and could impair their ability to fulfill their financial obligations to the Company. The spread of the outbreak has caused disruptions in the U.S. economy. While there has been no material impact to the Company’s employees to date, COVID-19 could also potentially create widespread business continuity issues for the Company.

Congress, the President, and the Federal Reserve have taken several actions designed to cushion the economic fallout. Most notably, the Coronavirus Aid, Relief and Economic Security (CARES) Act was signed into law in March 2020 as a $2 trillion legislative package and the American Rescue Plan Act of 2021 was signed into law in March 2021 and provides an additional $1.9 trillion in spending to address the continued impact of COVID-19. The goal of these legislative measures is to prevent a severe economic downturn through various measures, including direct financial aid to American families and economic stimulus to significantly impacted industry sectors. The package also includes extensive emergency funding for hospitals and providers. In addition to the general impact of COVID-19, certain provisions of the CARES Act as well as other recent legislative and regulatory relief efforts may have a material impact on the Company’s operations.

The Company’s business is dependent upon the willingness and ability of its employees and customers to conduct banking and other financial transactions. If the global response to contain COVID-19 escalates further or is unsuccessful, the Company could experience a material adverse effect on its business, financial condition, results of operations and cash flows. While it is not possible to know the full universe or extent that the impact of COVID-19, and resulting measures to curtail its spread, will have on the Company’s operations, the Company is disclosing potentially material items of which it is aware.

Results of Operations

The Company’s net interest income could decrease due to COVID-19. In keeping with guidance from regulators, the Company worked with certain COVID-19 affected borrowers to reduce their loan payments by modifying the loan agreements to allow for interest only payments. The loan modification periods ranged from 6 months to 24 months and were intended to provide payment relief to borrowers over the period of time that COVID-19 is expected to continue to negatively affect the profitability of the borrowers’ businesses. Although the modified loan payments have been made as agreed and interest income has been recognized by the Company, should the borrowers be negatively affected by COVID-19 for a period of time that extends beyond the loan modification periods, it’s possible the borrowers may not be able to resume regular principal and interest payments in future periods and the Company may no longer be able to accrue interest income on the loans.

The Company’s net interest income could also decrease due to adverse economic conditions that may result from COVID-19 and a related decrease in loan demand, causing a shift in earning asset balances from loans into lower yielding interest-bearing deposits in banks and securities. The decrease in loan demand could also increase the competition for loans and result in a reduction of loan rates offered by other financial institutions.

The Company's noninterest income could decrease due to COVID-19. Service charges on deposits decreased after the pandemic was declared and may decrease again in future periods. Wealth management revenue may decrease in future periods if the market values of investments decline and mortgage fee income may decrease from less home buying and refinancing activity in the Company's market area. At this time, the Company is unable to project the materiality of such an impact but recognizes it may unfavorably affect its noninterest income in future periods.

The Company’s noninterest expense could increase due to COVID-19. If the Bank's asset quality worsens, it may incur additional loan expenses in future periods from obtaining updated appraisals on loan collateral, additional legal and professional expenses related to the resolution of problem loans, an increase in other real estate owned expense, and potential losses on the sale of other real estate owned.

At this time, the Company is unable to project the full extent or materiality of the foregoing impacts but recognizes the breadth of the economic impacts of COVID-19 may have an unfavorable impact on net interest income, noninterest income, noninterest expense, and loan customers' ability to repay loans, in future periods.

Capital and Liquidity

While the Company believes it has sufficient capital to withstand an extended economic recession brought about by COVID-19, its reported and regulatory capital ratios could be adversely impacted by provision for loan losses in future periods. Larger amounts of provision for loan losses may result from factors including higher specific reserves on newly identified and existing impaired loans, higher levels of net charge-offs, and additional adjustments to qualitative factors in the general reserve component of the Bank’s allowance for loan losses. In March 2020, the Company suspended future stock repurchases under its stock repurchase program due to the economic uncertainty caused by the pandemic, and the program remained suspended for the remainder of 2020. The Company has not authorized another stock repurchase program due to the continued uncertainty and potential impact of the pandemic on the economy and the Bank’s customers. In June 2020, the Company issued $5.0 million of subordinated debt to strengthen holding company liquidity and to remain a source of strength to the Bank in the event of a severe economic downturn resulting from the pandemic. The Company will continue to update its enterprise risk assessment and capital plans as the operating environment develops.

The Company maintains access to multiple sources of liquidity. While wholesale funding markets have remained open, interest rates for short term funding could become volatile. If funding costs would become elevated for an extended period of time, it may have an adverse effect on the Company’s net interest margin. If an extended recession causes large numbers of the Company’s deposit customers to withdraw their funds, the Company could become more reliant on volatile or more expensive sources of funding.

Processes, Controls and Business Continuity Plan

The Company continues to operate under its Pandemic Continuity of Operations Plan that includes a remote working strategy. The Company has not incurred additional material costs related to employees working remotely. No material operational or internal control challenges or risks have been identified to date. The Company does not anticipate significant challenges to its ability to maintain its systems and controls in light of the measures the Company has taken to prevent the spread of COVID-19. The Company does not currently face any material resource constraint through the implementation of its business continuity plan.

Lending Operations and Accommodations to Borrowers

In keeping with regulatory guidance to work with borrowers during this unprecedented situation, the Company offered a payment deferral program, primarily during the second and third quarters of 2020, for its individual and business customers adversely affected by the pandemic that deferred loan payments for up to 90 days. There were no loans remaining in the program at September 30, 2021. In accordance with the CARES Act and interagency guidance issued in August 2020, these short-term loan payment deferrals were not considered troubled debt restructurings.

During the fourth quarter of 2020, and during the first half of 2021, the Bank modified terms of certain loans for customers that continued to be negatively impacted by the pandemic. The loan modifications lowered borrower loan payments by allowing interest only payments for periods ranging between 6 and 24 months. All loans modified were in the Bank’s commercial real estate loan portfolio and totaled $13.3 million at September 30, 2021, with $13.2 million in the Bank’s commercial real estate loan portfolio and $83 thousand in the commercial and industrial loans portfolio. The loans were comprised of $11.6 million in the lodging sector and $1.7 million in the leisure sector.

The Bank actively participated as a lender in the U.S. Small Business Administration’s (“SBA”) Paycheck Protection Program (“PPP”) to support local small businesses and non-profit organizations by providing forgivable loans. Loan fees received from the SBA are accreted by the Bank into income evenly over the life of the loans, net of loan origination costs, through interest and fees on loans. PPP loans totaled $22.8 million at September 30, 2021, with $1.3 million scheduled to mature in the second and third quarters of 2022, and $21.5 million scheduled to mature in the first and second quarters of 2026. The Company believes the majority of these loans will ultimately be forgiven and repaid by the SBA in accordance with the terms of the program. It is the Company’s understanding that loans funded through the PPP program are fully guaranteed by the U.S. government. Should those circumstances change, the Company could be required to establish additional allowance for loan losses through additional provision for loan losses charged to earnings.

The Bank recognized $737 thousand and $247 thousand of accretion on deferred PPP income, net origination costs, through interest and fees on loans for three month periods ending September 30, 2021 and 2020, respectively, and recognized $1.8 million and $429 thousand for the nine months ended September 30, 2021 and 2020, respectively. The total amount of deferred PPP income, net of origination costs, not yet been recognized through interest and fees on loans totaled $652 thousand at September 30, 2021.

Asset Quality

The economic impact of the pandemic had an unfavorable impact on the financial condition of certain Bank customers. The Bank entered into loan modification agreements in the fourth quarter of 2020, and during the first half of 2021, to provide relief to certain customers that were continuing to experience temporary business interruptions from the pandemic. The modifications were designed to help borrowers continue their business operations while minimizing potential loan charge-offs. The magnitude of the potential decline in the Bank’s loan quality will likely depend on the length and extent that the Bank’s customers experience business interruptions from the pandemic.

Business Combinations

On July 1, 2021, the Company completed the acquisition of The Bank of Fincastle (Fincastle) for an aggregate purchase price of $33.8 million of cash and stock. On September 30, 2021, the Bank acquired $82.0 million of loans and certain fixed assets from SmartBank related to their Richmond area branch. The Bank purchased the fixed assets for an amount equal to SmartBank’s book value. Additional information about these acquisitions is presented in Note 17.

Adoption of New Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12, “Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes” (ASU 2019-12). 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. ASU 2019-12 was effective for the Company on January 1, 2021. The adoption of this standard did not have a material effect on the Company's consolidated financial statements.

In January 2020, the FASB issued ASU No. 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” (ASU 2020-01). 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 2016-01 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. ASU 2020-01 was effective for the Company on January 1, 2021. The adoption of this standard did not have a material effect on the Company's consolidated financial statements.

In October 2020, the FASB issued ASU No. 2020-08, “Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable fees and Other Costs” (ASU 2020-08). 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. ASU 2020-08 was effective for the Company on January 1, 2021. The adoption of this standard did not have a material effect on the Company's consolidated financial statements.

In December 2020, the Consolidated Appropriations Act of 2021 (CAA) was passed.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13). 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 ASU’s 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), such as the Company, 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. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements. The Company has formed a committee to address the compliance requirements of this ASU, which has analyzed gathered data, defined loan pools and segments, and selected methods for applying the concepts included in this ASU. The Company is in the process of testing selected models, building policy and processing documentation, modeling the impact of the ASU on the capital and strategic plans, performing model validation, and finalizing policies and procedures. This guidance may result in material changes in the Company's accounting for credit losses of financial instruments.

Effective November 25, 2019, the SEC adopted Staff Accounting Bulletin (SAB) 119. SAB 119 updated portions of SEC interpretative guidance to align with FASB 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 No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04). These amendments 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 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 No. 2021-01 “Reference Rate Reform (Topic 848): Scope” (ASU 2021-01). 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 is currently in the process of identifying loans and other financial instruments that are directly or indirectly influenced by LIBOR. The Company is assessing ASU 2020-04 and its impact on the Company's transition away from LIBOR for its loan and other financial instruments.

In August 2020, the FASB issued ASU No. 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" (ASU 2020-06). The ASU simplifies accounting for convertible instruments by removing major separation models required under current U.S. 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 (EPS) 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.
