Accounting Policies [Abstract]
General	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 June 30, 2016 and December 31, 2015, the statements of income and comprehensive income (loss) for the three and six months ended June 30, 2016 and 2015 and the cash flows and changes in shareholders’ equity for the six months ended June 30, 2016 and 2015. 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, 2015. Operating results for the three and six month periods ended June 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. Recent Accounting Pronouncements In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This update is intended to provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have an impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: 1) Requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. 2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). 4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, “Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” Among other things, the amendments in ASU 2016-07, eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-07 to have a material impact on its consolidated financial statements. During March 2016, the FASB issued ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The amendments in this ASU simplify several aspects of the accounting for share-based payment award transactions including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the statement of cash flows. The amendments are effective for public companies for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently assessing the impact that ASU 2016-09 will have on its consolidated financial statements. During June 2016, the FASB issued ASU No. 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 amendments in this ASU are effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. For public companies that are not SEC filers, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements.

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Impairment is considered to be other-than-temporary if the Company (1) intends to sell the security, (2) more likely than not will be required to sell the security before recovering its cost, or (3) does not expect to recover the security’s entire amortized cost basis. Presently, the Company does not intend to sell any of these securities, does not expect to be required to sell these securities, and expects to recover the entire amortized cost of all the securities. At June 30, 2016, there were thirteen U.S. agency and mortgage-backed securities and one obligation of a state and political subdivision in an unrealized loss position. One hundred percent of the Company’s investment portfolio is considered investment grade. The weighted-average re-pricing term of the portfolio was 3.9 years at June 30, 2016. At December 31, 2015, there were fifty-two U.S. agency and mortgage-backed securities and thirteen obligations of states and political subdivisions in an unrealized loss position. One hundred percent of the Company’s investment portfolio was considered investment grade at December 31, 2015. The weighted-average re-pricing term of the portfolio was 4.6 years at December 31, 2015. The unrealized losses at June 30, 2016 in the U.S. agency and mortgage-backed securities portfolio and the obligation of states and political subdivisions portfolio were related to changes in market interest rates and not credit concerns of the issuers. For the three and six months ended June 30, 2016, the Company sold one security from the held to maturity portfolio. The Company recognized no gain or loss related to the sale as the carrying value of the security sold equaled the proceeds from the sale of $657 thousand. The sale of this security was in response to credit deterioration of the issuer. There were no sales of securities from the held to maturity portfolio for the three and six month periods ended June 30, 2015. The amortized cost and fair value of securities at June 30, 2016 by contractual maturity are shown below (in thousands). Expected maturities of mortgage-backed securities will differ from contractual maturities because borrowers may have the right to prepay obligations with or without call or prepayment penalties. Corporate equity securities are not included in the maturity categories in the following maturity summary because they do not have a stated maturity date. Available for Sale Held to Maturity Amortized Fair Amortized Fair Cost Value Cost Value Due within one year $ 1,666 $ 1,672 $ — $ — Due after one year through five years 9,649 9,769 1,111 1,131 Due after five years through ten years 13,246 13,578 16,355 16,761 Due after ten years 68,791 69,531 39,935 40,483 Corporate equity securities 1 16 — — $ 93,353 $ 94,566 $ 57,401 $ 58,375 Federal Home Loan Bank, Federal Reserve Bank and Community Bankers’ Bank stock are generally viewed as long-term investments and as restricted securities, which are carried at cost, because there is a minimal market for the stock. Therefore, when evaluating restricted securities for impairment, their value is based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. The Company does not consider these investments to be other-than-temporarily impaired at June 30, 2016, and no impairment has been recognized. The composition of restricted securities at June 30, 2016 and December 31, 2015 was as follows (in thousands): June 30, December 31, Federal Home Loan Bank stock $ 1,133 $ 466 Federal Reserve Bank stock 875 875 Community Bankers’ Bank stock 50 50 $ 2,058 $ 1,391

Loans	Note 3. Loans Loans at June 30, 2016 and December 31, 2015 are summarized as follows (in thousands): June 30, December 31, Real estate loans: Construction and land development $ 33,232 $ 33,135 Secured by 1-4 family residential 196,295 189,286 Other real estate loans 200,162 181,447 Commercial and industrial loans 24,721 24,048 Consumer and other loans 11,136 11,083 Total loans $ 465,546 $ 438,999 Allowance for loan losses (5,734 ) (5,524 ) Loans, net $ 459,812 $ 433,475 Net deferred loan fees included in the above loan categories were $67 thousand at June 30, 2016 and net deferred loan costs included in the above loan categories were $54 thousand at December 31, 2015. Consumer and other loans included $334 thousand and $257 thousand of demand deposit overdrafts at June 30, 2016 and December 31, 2015, respectively. Risk characteristics of each loan portfolio class that are considered by the Company include: • 1-4 family residential mortgage loans carry risks associated with the continued creditworthiness of the borrower and changes in the value of the collateral. • Real estate construction and land development loans carry risks that the project may not be finished according to schedule, the project may not be finished according to budget and the value of the collateral may, at any point in time, be less than the principal amount of the loan. Construction loans also bear the risk that the general contractor, who may or may not be a loan customer, may be unable to finish the construction project as planned because of financial pressure or other factors unrelated to the project. • Other real estate loans carry risks associated with the successful operation of a business or a real estate project, in addition to other risks associated with the ownership of real estate, because repayment of these loans may be dependent upon the profitability and cash flows of the business or project. • Commercial and industrial loans carry risks associated with the successful operation of a business because repayment of these loans may be dependent upon the profitability and cash flows of the business. In addition, there is risk associated with the value of collateral other than real estate which may depreciate over time and cannot be appraised with as much reliability. • Consumer and other loans carry risk associated with the continued creditworthiness of the borrower and the value of the collateral, i.e. rapidly depreciating assets such as automobiles, or lack thereof. Consumer loans are likely to be immediately adversely affected by job loss, divorce, illness or personal bankruptcy, or other changes in circumstances. The following tables provide a summary of loan classes and an aging of past due loans as of June 30, 2016 and December 31, 2015 (in thousands): June 30, 2016 30-59 60-89 > 90 Total Current Total Non-accrual 90 Days Real estate loans: Construction and land development $ 111 $ 126 $ — $ 237 $ 32,995 $ 33,232 $ 1,539 $ — Secured by 1-4 family residential 768 202 269 1,239 195,056 196,295 345 — Other real estate loans 331 590 125 1,046 199,116 200,162 2,089 — Commercial and industrial 9 34 8 51 24,670 24,721 84 8 Consumer and other loans 14 — 3 17 11,119 11,136 — 3 Total $ 1,233 $ 952 $ 405 $ 2,590 $ 462,956 $ 465,546 $ 4,057 $ 11 December 31, 2015 30-59 60-89 > 90 Total Current Total Non-accrual 90 Days Real estate loans: Construction and land development $ — $ — $ — $ — $ 33,135 $ 33,135 $ 1,269 $ — Secured by 1-4 family residential 635 18 264 917 188,369 189,286 346 — Other real estate loans 387 358 790 1,535 179,912 181,447 2,145 — Commercial and industrial — — 92 92 23,956 24,048 94 92 Consumer and other loans 20 — — 20 11,063 11,083 — — Total $ 1,042 $ 376 $ 1,146 $ 2,564 $ 436,435 $ 438,999 $ 3,854 $ 92 Credit Quality Indicators As part of the ongoing monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to the risk grading of specified classes of loans. The Company utilizes a risk grading matrix to assign a rating to each of its loans. The loan ratings are summarized into the following categories: pass, special mention, substandard, doubtful and loss. Pass rated loans include all risk rated credits other than those included in special mention, substandard or doubtful. Loans classified as loss are charged-off. Loan officers assign risk grades to loans at origination and as renewals arise. The Bank’s Credit Administration department reviews risk grades for accuracy on a quarterly basis and as credit issues arise. In addition, a certain amount of loans are reviewed each year through the Company’s internal and external loan review process. A description of the general characteristics of the loan grading categories is as follows: Pass – Special Mention – Substandard – Doubtful – Loss – The following tables provide an analysis of the credit risk profile of each loan class as of June 30, 2016 and December 31, 2015 (in thousands): June 30, 2016 Pass Special Substandard Doubtful Total Real estate loans: Construction and land development $ 27,121 $ 2,095 $ 4,016 $ — $ 33,232 Secured by 1-4 family residential 190,518 2,566 3,211 — 196,295 Other real estate loans 185,740 8,330 6,092 — 200,162 Commercial and industrial 24,166 401 154 — 24,721 Consumer and other loans 11,136 — — — 11,136 Total $ 438,681 $ 13,392 $ 13,473 $ — $ 465,546 December 31, 2015 Pass Special Substandard Doubtful Total Real estate loans: Construction and land development $ 26,371 $ 2,587 $ 4,177 $ — $ 33,135 Secured by 1-4 family residential 182,595 3,376 3,315 — 189,286 Other real estate loans 165,310 9,977 6,160 — 181,447 Commercial and industrial 23,351 432 265 — 24,048 Consumer and other loans 11,083 — — — 11,083 Total $ 408,710 $ 16,372 $ 13,917 $ — $ 438,999

The “Unpaid Principal Balance” represents the outstanding principal balance on each loan represented in the table plus any amounts that have been charged off on each loan and/or payments that have been applied towards principal on non-accrual loans. As of June 30, 2016, one loan totaling $660 thousand was classified as a troubled debt restructuring (TDR) and included in impaired loans in the disclosure above. At June 30, 2016, the loan classified as a TDR was not performing under the restructured terms and was considered a non-performing asset. There were $982 thousand in TDRs at December 31, 2015, $317 thousand of which were performing under the restructured terms. Modified terms under TDRs may include rate reductions, extension of terms that are considered to be below market, conversion to interest only, and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of the collateral. There were no loans modified under TDRs during the three and six month periods ended June 30, 2016 and 2015. For the three and six months ended June 30, 2016 and 2015, there were no troubled debt restructurings that subsequently defaulted within twelve months of the loan modification. Management defines default as over ninety days past due or the foreclosure and repossession of the collateral or charge-off of the loan during the twelve month period subsequent to the modification.

Other Borrowings The Bank had unused lines of credit totaling $118.6 million and $128.1 million available with non-affiliated banks at June 30, 2016 and December 31, 2015, respectively. These amounts primarily consist of a blanket floating lien agreement with the Federal Home Loan Bank of Atlanta (FHLB) in which the Bank can borrow up to 19% of its total assets. The unused line of credit with FHLB totaled $74.5 million at June 30, 2016. The Bank had collateral pledged on the borrowing line at June 30, 2016 and December 31, 2015 including real estate loans totaling $108.0 million and $105.1 million, respectively, and Federal Home Loan Bank stock with a book value of $1.1 million and $466 thousand, respectively. At June 30, 2016, the Bank had borrowings from the FHLB totaling $12.0 million which matured July 1, 2016. The interest rate on this note payable was 0.57%. The Bank did not have borrowings from the FHLB at December 31, 2015.

Capital Requirements

Capital Requirements	6 Months Ended
	Jun. 30, 2016
Banking and Thrift [Abstract]
Capital Requirements	Note 7. Capital Requirements The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk-weightings and other factors. Prompt corrective action provisions are not applicable to bank holding companies. The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective January 1, 2015, with full compliance of all the requirements being phased in over a multi-year schedule, and becoming fully phased in by January 1, 2019. As part of the new requirements, the common equity Tier 1 capital ratio is calculated and utilized in the assessment of capital for all institutions. The final rules also established a “capital conservation buffer” above the new regulatory minimum capital requirements. The capital conservation buffer is being phased-in over four years beginning on January 1, 2016. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following table) of total (as defined in the regulations), Tier 1 (as defined), and common equity Tier 1 capital (as defined) to risk-weighted assets (as defined), and of Tier 1 capital to average assets. Management believes, as of June 30, 2016 and December 31, 2015, that the Bank met all capital adequacy requirements to which it is subject. As of June 30, 2016, the most recent notification from the Federal Reserve Bank categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 12. Fair Value Measurements The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the “Fair Value Measurement and Disclosures” topic of FASB ASC, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. Fair Value Hierarchy In accordance with this guidance, the Company groups its assets and liabilities generally measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 – Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 – Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires a significant management judgment or estimation. An instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following describes the valuation techniques used by the Company to measure certain assets recorded at fair value on a recurring basis in the financial statements: Securities available for sale Securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, when available (Level 1). If quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable market data. Third party vendors compile prices from various sources and may determine the fair value of identical or similar securities by using pricing models that consider observable market data (Level 2). The following tables present the balances of assets measured at fair value on a recurring basis as of June 30, 2016 and December 31, 2015 (in thousands). Fair Value Measurements at June 30, 2016 Description Balance as of Quoted Significant Significant Securities available for sale U.S. agency and mortgage-backed securities $ 79,674 $ — $ 79,674 $ — Obligations of states and political subdivisions 14,876 — 14,876 — Corporate equity securities 16 16 — — $ 94,566 $ 16 $ 94,550 $ — Fair Value Measurements at December 31, 2015 Description Balance as of Quoted Significant Significant Securities available for sale U.S. agency and mortgage-backed securities $ 89,337 $ — $ 89,337 $ — Obligations of states and political subdivisions 16,214 — 16,214 — Corporate equity securities 8 8 — — $ 105,559 $ 8 $ 105,551 $ — Certain assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets. The following describes the valuation techniques used by the Company to measure certain assets recorded at fair value on a nonrecurring basis in the financial statements: Loans held for sale Loans held for sale are carried at the lower of cost or market value. These loans currently consist of one-to-four family residential loans originated for sale in the secondary market. Fair value is based on the price secondary markets are currently offering for similar loans using observable market data which is not materially different than cost due to the short duration between origination and sale (Level 2). As such, the Company records any fair value adjustments on a nonrecurring basis. No nonrecurring fair value adjustments were recorded on loans held for sale during six months ended June 30, 2016 and the year ended December 31, 2015. Impaired Loans Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due according to the contractual terms of the loan agreements will not be collected. The measurement of loss associated with impaired loans can be based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the observable market price of the loan, or the fair value of the collateral. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. The vast majority of the Company’s collateral is real estate. The value of real estate collateral is determined utilizing a market valuation approach based on an appraisal conducted by an independent, licensed appraiser using observable market data (Level 2) within the last twelve months. However, if the collateral is a house or building in the process of construction or if an appraisal of the property is more than one year old and not solely based on observable market comparables or management determines the fair value of the collateral is further impaired below the appraised value, then a Level 3 valuation is considered to measure the fair value. The value of business equipment is based upon an outside appraisal, of one year or less, if deemed significant, or the net book value on the applicable business’s financial statements if not considered significant using observable market data. Likewise, values for inventory and accounts receivables collateral are based on financial statement balances or aging reports (Level 3). Impaired loans allocated to the allowance for loan losses are measured at fair value on a nonrecurring basis. Any fair value adjustments are recorded in the period incurred as provision for (or recovery of) loan losses on the Consolidated Statements of Income. Other real estate owned Loans are transferred to other real estate owned when the collateral securing them is foreclosed on or acquired through a deed in lieu of foreclosure. The measurement of loss associated with other real estate owned is based on the appraisal documents and assessed the same way as impaired loans described above. Any fair value adjustments are recorded in the period incurred as other real estate owned expense on the Consolidated Statements of Income. The following tables summarize the Company’s assets that were measured at fair value on a nonrecurring basis during the periods (dollars in thousands): Fair Value Measurements at June 30, 2016 Description Balance as of Quoted Significant Significant Impaired loans, net $ 364 $ — $ — $ 364 Other real estate owned, net 442 — — 442 Fair Value Measurements at December 31, 2015 Description Balance as of Quoted Significant Significant Impaired loans, net $ 377 $ — $ — $ 377 Other real estate owned, net 2,679 — — 2,679 Quantitative information about Level 3 Fair Value Measurements for June 30, 2016 Fair Value Valuation Technique Unobservable Input Range (Weighted- Impaired loans, net $ 364 Property appraisals Selling cost 10% Other real estate owned, net $ 442 Property appraisals Selling cost 7% Quantitative information about Level 3 Fair Value Measurements for December 31, 2015 Fair Value Valuation Technique Unobservable Input Range (Weighted- Impaired loans, net $ 377 Property appraisals Selling cost 2-10% (5%) Other real estate owned, net $ 2,679 Property appraisals Selling cost 7% Accounting guidance requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. The methodologies for other financial assets and financial liabilities are discussed below: Cash and Cash Equivalents and Federal Funds Sold The carrying amounts of cash and short-term instruments approximate fair values. Securities Held to Maturity Certain debt securities that management has the positive intent and ability to hold until maturity are recorded at amortized cost. Fair values are determined in a manner that is consistent with securities available for sale. Restricted Securities The carrying value of restricted securities approximates fair value based on redemption provisions. Loans For variable-rate loans that re-price frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for all other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. Deposit Liabilities The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-rate certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. Accrued Interest Accrued interest receivable and payable were estimated to equal the carrying value due to the short-term nature of these financial instruments. Borrowings and Federal Funds Purchased The carrying amounts of federal funds purchased and other short-term borrowings maturing within ninety days approximate their fair values. Fair values of all other borrowings are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Bank Owned Life Insurance Bank owned life insurance represents insurance policies on officers, directors, and past directors of the Company. The cash values of these policies are estimates using information provided by insurance carriers. These policies are carried at their cash surrender value, which approximates the fair value. Commitments and Unfunded Credits The fair value of commitments to extend credit is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of stand-by letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. At June 30, 2016 and December 31, 2015, fair value of loan commitments and standby letters of credit was immaterial. The carrying values and estimated fair values of the Company’s financial instruments at June 30, 2016 and December 31, 2015 are as follows (in thousands): Fair Value Measurements at June 30, 2016 Using Carrying Quoted Significant Significant Fair Value Financial Assets Cash and short-term investments $ 50,743 $ 50,743 $ — $ — $ 50,743 Securities available for sale 94,566 16 94,550 — 94,566 Securities held to maturity 57,401 — 56,840 1,535 58,375 Restricted securities 2,058 — 2,058 — 2,058 Loans held for sale 1,819 — 1,819 — 1,819 Loans, net 459,812 — — 468,394 468,394 Bank owned life insurance 13,935 — 13,935 — 13,935 Accrued interest receivable 1,612 — 1,612 — 1,612 Financial Liabilities Deposits $ 630,346 $ — $ 496,867 $ 133,630 $ 630,497 Other borrowings 12,000 — — 11,998 11,998 Subordinated debt 4,921 — — 5,013 5,013 Junior subordinated debt 9,279 — — 8,111 8,111 Accrued interest payable 98 — 98 — 98 Fair Value Measurements at December 31, 2015 Using Carrying Quoted Significant Significant Fair Value Financial Assets Cash and short-term investments $ 39,334 $ 39,334 $ — $ — $ 39,334 Securities available for sale 105,559 8 105,551 — 105,559 Securities held to maturity 66,519 — 64,938 1,500 66,438 Restricted securities 1,391 — 1,391 — 1,391 Loans held for sale 323 — 323 — 323 Loans, net 433,475 — — 438,392 438,392 Bank owned life insurance 11,742 — 11,742 — 11,742 Accrued interest receivable 1,661 — 1,661 — 1,661 Financial Liabilities Deposits $ 627,116 $ — $ 486,015 $ 140,306 $ 626,321 Subordinated debt 4,913 — — 4,913 4,913 Junior subordinated debt 9,279 — — 8,141 8,141 Accrued interest payable 117 — 117 — 117 The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the fair values of the Company’s financial instruments will change when interest rate levels change and that change may be either favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. However, borrowers with fixed rate obligations are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk.

Stock Compensation Plans	Note 14. Stock Compensation Plans On May 13, 2014, the Company’s shareholders approved the First National Corporation 2014 Stock Incentive Plan, which makes available up to 240,000 shares of common stock for the granting of stock options, restricted stock awards, stock appreciation rights and other stock-based awards. Awards are made at the discretion of the Board of Directors and compensation cost equal to the fair value of the award is recognized over the vesting period. Restricted Stock Units Restricted stock units are an award of units that correspond in number and value to a specified number of shares of employer stock which the recipient receives according to a vesting plan and distribution schedule after achieving required performance milestones or upon remaining with the employer for a particular length of time. Each restricted stock unit that vests entitles the recipient to receive one share of common stock on a specified issuance date. In the first quarter of 2016, 9,130 restricted stock units were granted to employees, with 3,047 units vesting immediately and 6,083 units subject to a two year vesting schedule with one half of the units vesting each year on the grant date anniversary. The recipient does not have any stockholder rights, including voting, dividend or liquidation rights, with respect to the shares underlying awarded restricted stock units until vesting has occurred and the recipient becomes the record holder of those shares. The unvested restricted stock units will vest on the established schedule if the employees remain employed by the Company on future vesting dates. A summary of the activity for the Company’s restricted stock units for the period indicated is presented in the following table: June 30, 2016 Shares Weighted Unvested, beginning of period 8,353 $ 9.00 Granted 9,130 8.80 Vested (7,224 ) 8.92 Forfeited — — Unvested, end of period 10,259 $ 8.88 At June 30, 2016, based on restricted stock unit awards outstanding at that time, the total unrecognized pre-tax compensation expense related to unvested restricted stock unit awards was $66 thousand. This expense is expected to be recognized through 2018. Compensation expense related to restricted stock unit awards recognized for the six months ended June 30, 2016 and 2015 totaled $56 thousand and $52 thousand, respectively. As of June 30, 2016, the Company does not expect the forfeiture of any unvested restricted stock units.

Business Combinations [Abstract]
Acquisition	Note 16. Acquisition On April 17, 2015, the Bank completed its acquisition of six branch banking operations located in Virginia from Bank of America, National Association (the Acquisition). The Bank paid cash of $6.6 million for the deposits and premises and equipment. The Bank acquired all related premises and equipment valued at $4.5 million and assumed $186.8 million of deposit liabilities. No loans were acquired in the transaction. The transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged were recorded at estimated fair values on the acquisition date. The Bank engaged third party specialists to assist in valuing certain assets, including the real estate, core deposit intangible, and goodwill (bargain purchase gain) that resulted from the Acquisition. The following table provides a preliminary assessment of the consideration transferred, assets purchased, and the liabilities assumed (in thousands): As Recorded Fair Value and As Recorded Consideration paid: Cash paid $ 6,618 Total consideration $ 6,618 Assets acquired: Cash and cash equivalents $ 186,119 $ — $ 186,119 Premises and equipment, net 2,165 2,330 4,495 Other assets 114 — 114 Core deposit intangibles — 2,910 2,910 Total assets acquired $ 188,398 $ 5,240 $ 193,638 Liabilities assumed: Deposits $ 186,119 $ 683 $ 186,802 Other liabilities 17 — 17 Total liabilities assumed $ 186,136 $ 683 $ 186,819 Net identifiable assets acquired over liabilities assumed $ 2,262 $ 4,557 $ 6,819 Goodwill (bargain purchase gain) $ (201 ) The bargain purchase gain from the transaction may have resulted from Bank of America’s decision to no longer operate bank branches in certain markets and their willingness to sell the related premises and equipment lower than fair value.

Fair Value Disclosures [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This update is intended to provide guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management is required under the new guidance to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued when preparing financial statements for each interim and annual reporting period. If conditions or events are identified, the ASU specifies the process that must be followed by management and also clarifies the timing and content of going concern footnote disclosures in order to reduce diversity in practice. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. Early adoption is permitted. The Company does not expect the adoption of ASU 2014-15 to have an impact on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: 1) Requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. 2) Requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. 3) Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables). 4) Eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the adoption of ASU 2016-01 to have a material impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) A lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is currently assessing the impact that ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, “Investments – Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting.” Among other things, the amendments in ASU 2016-07, eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Early adoption is permitted. The Company does not expect the adoption of ASU 2016-07 to have a material impact on its consolidated financial statements. During March 2016, the FASB issued ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The amendments in this ASU simplify several aspects of the accounting for share-based payment award transactions including: (a) income tax consequences; (b) classification of awards as either equity or liabilities; and (c) classification on the statement of cash flows. The amendments are effective for public companies for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company is currently assessing the impact that ASU 2016-09 will have on its consolidated financial statements. During June 2016, the FASB issued ASU No. 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 amendments in this ASU are effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. For public companies that are not SEC filers, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company is currently assessing the impact that ASU 2016-13 will have on its consolidated financial statements.
Fair Value Measurement and Disclosures	The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In accordance with the “Fair Value Measurement and Disclosures” topic of FASB ASC, the fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.
