Accounting Policies [Abstract]
General	Note 1. General The accompanying unaudited consolidated financial statements of First National Corporation (the Company) and its subsidiaries, including 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, 2015 and December 31, 2014, the results of operations and comprehensive income for the three and nine months ended September 30, 2015 and 2014 and the cash flows and changes in shareholders’ equity for the nine months ended September 30, 2015 and 2014. 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, 2014. Operating results for the three and nine month periods ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. Recent Accounting Pronouncements In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures”. This ASU aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. The new guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement. The amendments in the ASU also require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. Additional disclosures will be required for the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The amendments in this ASU are effective for the first interim or annual period beginning after December 15, 2014; however, the disclosure for transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption is not permitted. The adoption of ASU 2014-11 did not have an impact on the Company’s consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, “Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. Existing guidance in “Compensation – Stock Compensation (Topic 718)”, should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis. The Company does not expect the adoption of ASU 2014-12 to have an impact on its consolidated financial statements. 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 November 2014, the FASB issued ASU No. 2014-16, “Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” The amendments in this ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have an impact on its consolidated financial statements. In January 2015, the FASB issued ASU No. 2015-01, “Income Statement—Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The amendments in this ASU eliminate from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU 2015-01 to have an impact on its consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” The amendments in this ASU are intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB Accounting Standards Codification™ and improves current GAAP by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. ASU 2015-02 may be applied retrospectively in previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated. The Company does not expect the adoption of ASU 2015-02 to have an impact on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments in this ASU are intended to simplify the presentation of debt issuance costs. These amendments require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments in this ASU are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU 2015-03 to have an impact on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The amendments in this ASU provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The amendments in this ASU are effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. An entity can elect to adopt the amendments either: (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. The Company is currently assessing the impact that ASU 2015-05 will have on its consolidated financial statements. In May 2015, the FASB issued ASU No. 2015-08, “Business Combinations (Topic 805): Pushdown Accounting – Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115.” The amendments in ASU 2015-08 amend various SEC paragraphs pursuant to the issuance of Staff Accounting Bulletin No. 115, Topic 5: Miscellaneous Accounting, regarding various pushdown accounting issues, and did not have an impact on the Company’s consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-12, “Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965) – 1. Fully Benefit-Responsive Investment Contracts, 2. Plan Investment Disclosures, and 3. Measurement Date Practical Expedient.” The amendments within this ASU are in 3 parts. Among other things, Part 1 amendments designate contract value as the only required measure for fully benefit-responsive investment contracts; Part II amendments eliminate the requirement that plans disclose: (a) individual investments that represent 5 percent or more of net assets available for benefits; and (b) the net appreciation or depreciation for investments by general type requirements for both participant-directed investments and nonparticipant-directed investments. Part III amendments provide a practical expedient to permit plans to measure investments and investment-related accounts (e.g., a liability for a pending trade with a broker) as of a month-end date that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with month-end. The amendments in Parts 1 and 2 of this ASU are effective on a retrospective basis and Part 3 is effective on a prospective basis, for fiscal years beginning after December 15, 2015. Early adoption is permitted. The Company is currently assessing the impact that ASU 2015-12 will have on its consolidated financial statements. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date.” The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. All other entities may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities also may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which the entity first applies the guidance in ASU 2014-09. The Company does not expect the adoption of ASU 2015-14 (or ASU 2014-09) to have a material impact on its consolidated financial statements. In August 2015, the FASB issued ASU 2015-15, “Interest – Imputation of Interest (Subtopic 835-30) – Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting).” On April 7, 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires entities to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. The guidance in ASU 2015-03 (see paragraph 835-30-45-1A) does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff stated that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds these SEC comments to the “S” section of the Codification. The Company does not expect the adoption of ASU 2015-15 to have a material impact on its consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” The amendments in ASU 2015-16 require that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The Company does not expect the adoption of ASU 2015-16 to have a material impact 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 September 30, 2015, there were thirty-one U.S. agency and mortgage-backed securities and twenty obligations of state and political subdivisions 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 4.4 years at September 30, 2015. At December 31, 2014, there were twenty-nine U.S. agency and mortgage-backed securities and seven 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, 2014. The weighted-average re-pricing term of the portfolio was 3.9 years at December 31, 2014. The unrealized losses at September 30, 2015 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. The amortized cost and fair value of securities at September 30, 2015 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.

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 September 30, 2015, and no impairment has been recognized. Restricted securities are not part of the securities portfolio. The composition of restricted securities at September 30, 2015 and December 31, 2014 was as follows (in thousands): September 30, December 31, Federal Home Loan Bank stock $ 466 $ 470 Federal Reserve Bank stock 875 846 Community Bankers’ Bank stock 50 50 $ 1,391 $ 1,366

Loans	Note 3. Loans Loans at September 30, 2015 and December 31, 2014 are summarized as follows (in thousands): September 30, December 31, Real estate loans: Construction and land development $ 29,935 $ 29,475 Secured by 1-4 family residential 179,419 163,727 Other real estate loans 165,661 151,802 Commercial and industrial loans 19,950 21,166 Consumer and other loans 11,448 12,240 Total loans $ 406,413 $ 378,410 Allowance for loan losses (5,575 ) (6,718 ) Loans, net $ 400,838 $ 371,692 Net deferred loan costs included in the above loan categories were $128 thousand and $130 thousand at September 30, 2015 and December 31, 2014, respectively. Consumer and other loans included $421 thousand and $285 thousand of demand deposit overdrafts at September 30, 2015 and December 31, 2014, 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 table provides a summary of loan classes and an aging of past due loans as of September 30, 2015 and December 31, 2014 (in thousands): September 30, 2015 30-59 60-89 > 90 Total Current Total Non-accrual 90 Days Real estate loans: Construction and land development $ 430 $ — $ — $ 430 $ 29,505 $ 29,935 $ 1,911 $ — 1-4 family residential 1,004 19 269 1,292 178,127 179,419 298 55 Other real estate loans 419 — 1,247 1,666 163,995 165,661 2,622 — Commercial and industrial 188 — 92 280 19,670 19,950 99 92 Consumer and other loans 18 6 — 24 11,424 11,448 — — Total $ 2,059 $ 25 $ 1,608 $ 3,692 $ 402,721 $ 406,413 $ 4,930 $ 147 December 31, 2014 30-59 60-89 > 90 Total Current Total Non-accrual 90 Days Real estate loans: Construction and land development $ 2,441 $ 71 $ — $ 2,512 $ 26,963 $ 29,475 $ 1,787 $ — 1-4 family residential 504 323 754 1,581 162,146 163,727 1,342 — Other real estate loans 554 800 2,519 3,873 147,929 151,802 4,756 — Commercial and industrial 10 106 — 116 21,050 21,166 115 — Consumer and other loans 14 — — 14 12,226 12,240 — — Total $ 3,523 $ 1,300 $ 3,273 $ 8,096 $ 370,314 $ 378,410 $ 8,000 $ — 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 September 30, 2015 and December 31, 2014 (in thousands): September 30, 2015 Pass Special Substandard Doubtful Total Real estate loans: Construction and land development $ 23,168 $ 2,398 $ 4,369 $ — $ 29,935 Secured by 1-4 family residential 172,444 3,022 3,953 — 179,419 Other real estate loans 149,137 9,857 6,667 — 165,661 Commercial and industrial 19,243 429 278 — 19,950 Consumer and other loans 11,442 — 6 — 11,448 Total $ 375,434 $ 15,706 $ 15,273 $ — $ 406,413 December 31, 2014 Pass Special Substandard Doubtful Total Real estate loans: Construction and land development $ 20,476 $ 2,962 $ 6,037 $ — $ 29,475 Secured by 1-4 family residential 152,004 5,058 6,665 — 163,727 Other real estate loans 126,211 14,776 10,815 — 151,802 Commercial and industrial 20,428 463 275 — 21,166 Consumer and other loans 12,240 — — — 12,240 Total $ 331,359 $ 23,259 $ 23,792 $ — $ 378,410

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 September 30, 2015, loans classified as troubled debt restructurings (TDRs) and included in impaired loans in the disclosure above totaled $1.4 million. At September 30, 2015, $321 thousand of the loans classified as TDRs were performing under the restructured terms and were not considered non-performing assets. There were $1.9 million in TDRs at December 31, 2014, $790 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 nine month periods ended September 30, 2015 and the three month period ended September 30, 2014. There was one other real estate loan classified as a TDR during the nine month period ended September 30, 2014 because the loan term was extended at a below market rate of interest. The recorded investment for this loan prior to the modification totaled $283 thousand and the recorded investment after the modification totaled $344 thousand. For the three and nine months ended September 30, 2015 and 2014, 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 and charge-off of the loan during the twelve month period subsequent to the modification.

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. 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 September 30, 2015 and December 31, 2014, that the Bank met all capital adequacy requirements to which it is subject. As of September 30, 2015, the most recent notification from the Federal Reserve Bank categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum risk-based capital and leverage ratios as set forth in the following table. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Bank declared and paid cash dividends on common stock to the Company totaling $13.3 million during the third quarter of 2015. A comparison of the capital of the Bank at September 30, 2015 and December 31, 2014 with the minimum regulatory guidelines were as follows (dollars in thousands): Actual Minimum Capital Minimum Amount Ratio Amount Ratio Amount Ratio September 30, 2015: Total Capital (to Risk-Weighted Assets) $ 60,232 14.59 % $ 33,032 8.00 % $ 41,290 10.00 % Tier 1 Capital (to Risk-Weighted Assets) $ 55,066 13.34 % $ 24,774 6.00 % $ 33,032 8.00 % Common Equity Tier 1 Capital (to Risk-Weighted Assets) $ 55,066 13.34 % $ 18,580 4.50 % $ 26,838 6.50 % Tier 1 Capital (to Average Assets) $ 55,066 7.99 % $ 27,581 4.00 % $ 34,476 5.00 % December 31, 2014: Total Capital (to Risk-Weighted Assets) $ 71,941 19.14 % $ 30,077 8.00 % $ 37,596 10.00 % Tier 1 Capital (to Risk-Weighted Assets) $ 67,217 17.88 % $ 15,038 4.00 % $ 22,557 6.00 % Tier 1 Capital (to Average Assets) $ 67,217 12.90 % $ 20,841 4.00 % $ 26,051 5.00 %

Junior Subordinated Debt	Note 8. Junior Subordinated Debt On June 8, 2004, First National (VA) Statutory Trust II (Trust II), a wholly-owned subsidiary of the Company, was formed for the purpose of issuing redeemable capital securities, commonly known as trust preferred securities. On June 17, 2004, $5.0 million of trust preferred securities were issued through a pooled underwriting. The securities have a LIBOR-indexed floating rate of interest. The interest rate at September 30, 2015 and December 31, 2014 was 2.93% and 2.84%, respectively. The securities have a mandatory redemption date of June 17, 2034, and were subject to varying call provisions that began September 17, 2009. The principal asset of Trust II is $5.2 million of the Company’s junior subordinated debt with maturities and interest rates comparable to the trust preferred securities. The Trust’s obligations under the trust preferred securities are fully and unconditionally guaranteed by the Company. The Company is current on its interest payments on the junior subordinated debt. On July 24, 2006, First National (VA) Statutory Trust III (Trust III), a wholly-owned subsidiary of the Company, was formed for the purpose of issuing redeemable capital securities. On July 31, 2006, $4.0 million of trust preferred securities were issued through a pooled underwriting. The securities have a LIBOR-indexed floating rate of interest. The interest rate at September 30, 2015 and December 31, 2014 was 1.88% and 1.84%, respectively. The securities have a mandatory redemption date of October 1, 2036, and were subject to varying call provisions that began October 1, 2011. The principal asset of Trust III is $4.1 million of the Company’s junior subordinated debt with maturities and interest rates comparable to the trust preferred securities. The Trust’s obligations under the trust preferred securities are fully and unconditionally guaranteed by the Company. The Company is current on its interest payments on the junior subordinated debt. While these securities are debt obligations of the Company, they are included in capital for regulatory capital ratio calculations. Under present regulations, the junior subordinated debt may be included in Tier 1 capital for regulatory capital adequacy purposes as long as their amount does not exceed 25% of Tier 1 capital, including total junior subordinated debt. The portion of the junior subordinated debt not considered as Tier 1 capital, if any, may be included in Tier 2 capital. At September 30, 2015 and December 31, 2014, the total amount of junior subordinated debt issued by the Trusts was included in the Company’s Tier 1 capital.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 11. 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 an 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 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 September 30, 2015 and December 31, 2014 (in thousands). Fair Value Measurements at September 30, 2015 Description Balance as of Quoted Significant Significant Securities available for sale U.S. agency and mortgage-backed securities $ 92,863 $ — $ 92,863 $ — Obligations of states and political subdivisions 16,295 — 16,295 — Corporate equity securities 8 8 — — $ 109,166 $ 8 $ 109,158 $ — Fair Value Measurements at December 31, 2014 Description Balance as of Quoted Significant Significant Securities available for sale U.S. agency and mortgage-backed securities $ 67,029 $ — $ 67,029 $ — Obligations of states and political subdivisions 16,257 — 16,257 — Corporate equity securities 6 6 — — $ 83,292 $ 6 $ 83,286 $ — 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 nine months ended September 30, 2015 and the year ended December 31, 2014. 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 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. 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 September 30, 2015 Description Balance as of Quoted Significant Significant Impaired loans, net $ 1,446 $ — $ — $ 1,446 Other real estate owned, net 2,760 — — 2,760 Fair Value Measurements at December 31, 2014 Description Balance as of Quoted Significant Significant Impaired loans, net $ 2,976 $ — $ — $ 2,976 Other real estate owned, net 1,888 — — 1,888 Quantitative information about Level 3 Fair Value Measurements for September 30, 2015 Fair Value Valuation Technique Unobservable Input Range (Weighted-Average) Impaired loans, net $ 1,446 Property appraisals Selling cost 6-10% (8%) Other real estate owned, net $ 2,760 Property appraisals Selling cost 7% Quantitative information about Level 3 Fair Value Measurements for December 31, 2014 Fair Value Valuation Technique Unobservable Input Range (Weighted-Average) Impaired loans, net $ 2,976 Property appraisals Selling cost 10% Other real estate owned, net $ 1,888 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. 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-maturity 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 September 30, 2015 and December 31, 2014, 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 September 30, 2015 and December 31, 2014 are as follows (in thousands): Fair Value Measurements at September 30, 2015 Using Carrying Quoted Significant Significant Fair Value Financial Assets Cash and short-term investments $ 76,846 $ 76,846 $ — $ — $ 76,846 Securities available for sale 109,166 8 109,158 — 109,166 Securities held to maturity 54,276 — 54,303 — 54,303 Restricted securities 1,391 — 1,391 — 1,391 Loans held for sale 471 — 471 — 471 Loans, net 400,838 — — 408,853 408,853 Bank owned life insurance 11,627 — 11,627 — 11,627 Accrued interest receivable 1,543 — 1,543 — 1,543 Financial Liabilities Deposits $ 613,907 $ — $ 467,688 $ 146,177 $ 613,865 Other borrowings 7 — — 7 7 Junior subordinated debt 9,279 — — 8,623 8,623 Accrued interest payable 116 — 116 — 116 Fair Value Measurements at December 31, 2014 Using Carrying Quoted Significant Significant Fair Value Financial Assets Cash and short-term investments $ 24,845 $ 24,845 $ — $ — $ 24,845 Securities 83,292 6 83,286 — 83,292 Restricted securities 1,366 — 1,366 — 1,366 Loans held for sale 328 — 328 — 328 Loans, net 371,692 — — 378,930 378,930 Bank owned life insurance 11,357 — 11,357 — 11,357 Accrued interest receivable 1,261 — 1,261 — 1,261 Financial Liabilities Deposits $ 444,338 $ — $ 342,604 $ 101,606 $ 444,210 Federal funds purchased 52 — 52 — 52 Other borrowings 26 — — 26 26 Junior subordinated debt 9,279 — — 9,756 9,756 Accrued interest payable 135 — 135 — 135 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 13. 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 management and compensation cost equal to the fair value of the award is recognized over the vesting period. Stock Awards Whenever the Company deems it appropriate to grant a stock award, the recipient receives a specified number of unrestricted shares of employer stock. Stock awards may be made by the Company at its discretion without cash consideration and may be granted as settlement of a performance-based compensation award. During the third quarter of 2015, the Company granted and issued 960 shares of common stock to employees for their service during the recent branch acquisition. Compensation expense related to the awards totaled $8 thousand for the three and nine months ended September 30, 2015. 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 2015, 12,546 restricted stock units were granted to employees, with 4,182 units vesting immediately and 8,364 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: September 30, 2015 Shares Weighted Balance at January 1, 2015 — $ — Granted 12,546 9.00 Vested (4,182 ) 9.00 Forfeited — — Balance at September 30, 2015 8,364 $ 9.00 At September 30, 2015, 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 $51 thousand. This expense is expected to be recognized through 2017. Compensation expense related to restricted stock unit awards recognized for the nine months ended September 30, 2015 totaled $62 thousand. As of September 30, 2015, the Company does not expect the forfeiture of any unvested restricted stock units.

Acquisition	Note 15. 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. Fair values are preliminary and subject to refinement for up to one year after the closing date of the Acquisition as additional information regarding the closing date fair values becomes available. 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 by Fair Value and As Recorded by 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.

Subsequent Events [Abstract]
Subsequent Event	Note 16. Subsequent Events On October 30, 2015, the Company entered into a Subordinated Loan Agreement (the Agreement) to which the Company issued a subordinated term note due 2025 in the aggregate principal amount of $5.0 million (the Note). The Note bears interest at a fixed rate of 6.75% per annum. The Note is intended to qualify as Tier 2 capital for regulatory capital purposes. The Note has a maturity date of October 1, 2025. Subject to regulatory approval, the Company may prepay the Note, in part or in full, beginning on October 30, 2020. The Note will be an unsecured, subordinated obligation of the Company and will rank junior in right of payment to the Company’s senior indebtedness and to the Company’s obligations to its general creditors. The Note ranks equally with all other unsecured subordinated debt, except any which by its terms is expressly stated to be subordinated to the Note. The Note ranks senior to all current and future junior subordinated debt obligations, preferred stock and common stock of the Company. The Note is not convertible into common stock or preferred stock. The Agreement contains customary events of default such as the bankruptcy of the Company and the non-payment of principal or interest when due. The holder of the Note may accelerate the repayment of the Note only in the event of bankruptcy or similar proceedings and not for any other event of default. On November 6, 2015, the Company used the proceeds from the issuance of the Note, along with other funds, to redeem all 13,900 outstanding shares of its Fixed Rate Perpetual Preferred Stock, Series A at par for $13.9 million and all 695 outstanding shares of its Fixed Rate Perpetual Preferred Stock, Series B at par for $695 thousand.

Fair Value Disclosures [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2014, the FASB issued ASU No. 2014-11, “Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures”. This ASU aligns the accounting for repurchase-to-maturity transactions and repurchase agreements executed as a repurchase financing with the accounting for other typical repurchase agreements. The new guidance eliminates sale accounting for repurchase-to-maturity transactions and supersedes the guidance under which a transfer of a financial asset and a contemporaneous repurchase financing could be accounted for on a combined basis as a forward agreement. The amendments in the ASU also require a new disclosure for transactions economically similar to repurchase agreements in which the transferor retains substantially all of the exposure to the economic return on the transferred financial assets throughout the term of the transaction. Additional disclosures will be required for the nature of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The amendments in this ASU are effective for the first interim or annual period beginning after December 15, 2014; however, the disclosure for transactions accounted for as secured borrowings is required to be presented for annual periods beginning after December 15, 2014, and interim periods beginning after March 15, 2015. Early adoption is not permitted. The adoption of ASU 2014-11 did not have an impact on the Company’s consolidated financial statements. In June 2014, the FASB issued ASU No. 2014-12, “Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period”. The new guidance applies to reporting entities that grant employees share-based payments in which the terms of the award allow a performance target to be achieved after the requisite service period. The amendments in the ASU require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. Existing guidance in “Compensation – Stock Compensation (Topic 718)”, should be applied to account for these types of awards. The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted and reporting entities may choose to apply the amendments in the ASU either on a prospective or retrospective basis. The Company does not expect the adoption of ASU 2014-12 to have an impact on its consolidated financial statements. 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 November 2014, the FASB issued ASU No. 2014-16, “Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity.” The amendments in this ASU do not change the current criteria in U.S. GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required. The amendments clarify how current U.S. GAAP should be interpreted in evaluating the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share. Specifically, the amendments clarify that an entity should consider all relevant terms and features, including the embedded derivative feature being evaluated for bifurcation, in evaluating the nature of the host contract. Furthermore, the amendments clarify that no single term or feature would necessarily determine the economic characteristics and risks of the host contract. Rather, the nature of the host contract depends upon the economic characteristics and risks of the entire hybrid financial instrument. The amendments in this ASU also clarify that, in evaluating the nature of a host contract, an entity should assess the substance of the relevant terms and features (i.e., the relative strength of the debt-like or equity-like terms and features given the facts and circumstances) when considering how to weight those terms and features. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption, including adoption in an interim period, is permitted. The Company does not expect the adoption of ASU 2014-16 to have an impact on its consolidated financial statements. In January 2015, the FASB issued ASU No. 2015-01, “Income Statement—Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” The amendments in this ASU eliminate from U.S. GAAP the concept of extraordinary items. Subtopic 225-20, Income Statement - Extraordinary and Unusual Items, required that an entity separately classify, present, and disclose extraordinary events and transactions. Presently, an event or transaction is presumed to be an ordinary and usual activity of the reporting entity unless evidence clearly supports its classification as an extraordinary item. If an event or transaction meets the criteria for extraordinary classification, an entity is required to segregate the extraordinary item from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. The entity also is required to disclose applicable income taxes and either present or disclose earnings-per-share data applicable to the extraordinary item. The amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company does not expect the adoption of ASU 2015-01 to have an impact on its consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” The amendments in this ASU are intended to improve targeted areas of consolidation guidance for legal entities such as limited partnerships, limited liability corporations, and securitization structures (collateralized debt obligations, collateralized loan obligations, and mortgage-backed security transactions). In addition to reducing the number of consolidation models from four to two, the new standard simplifies the FASB Accounting Standards Codification™ and improves current GAAP by placing more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. The amendments in this ASU are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. ASU 2015-02 may be applied retrospectively in previously issued financial statements for one or more years with a cumulative-effect adjustment to retained earnings as of the beginning of the first year restated. The Company does not expect the adoption of ASU 2015-02 to have an impact on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, “Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” The amendments in this ASU are intended to simplify the presentation of debt issuance costs. These amendments require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU. The amendments in this ASU are effective for public business entities for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. The Company does not expect the adoption of ASU 2015-03 to have an impact on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” The amendments in this ASU provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The amendments do not change the accounting for a customer’s accounting for service contracts. As a result of the amendments, all software licenses within the scope of Subtopic 350-40 will be accounted for consistent with other licenses of intangible assets. The amendments in this ASU are effective for public business entities for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. An entity can elect to adopt the amendments either: (1) prospectively to all arrangements entered into or materially modified after the effective date; or (2) retrospectively. The Company is currently assessing the impact that ASU 2015-05 will have on its consolidated financial statements. In May 2015, the FASB issued ASU No. 2015-08, “Business Combinations (Topic 805): Pushdown Accounting – Amendments to SEC Paragraphs Pursuant to Staff Accounting Bulletin No. 115.” The amendments in ASU 2015-08 amend various SEC paragraphs pursuant to the issuance of Staff Accounting Bulletin No. 115, Topic 5: Miscellaneous Accounting, regarding various pushdown accounting issues, and did not have an impact on the Company’s consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-12, “Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), and Health and Welfare Benefit Plans (Topic 965) – 1. Fully Benefit-Responsive Investment Contracts, 2. Plan Investment Disclosures, and 3. Measurement Date Practical Expedient.” The amendments within this ASU are in 3 parts. Among other things, Part 1 amendments designate contract value as the only required measure for fully benefit-responsive investment contracts; Part II amendments eliminate the requirement that plans disclose: (a) individual investments that represent 5 percent or more of net assets available for benefits; and (b) the net appreciation or depreciation for investments by general type requirements for both participant-directed investments and nonparticipant-directed investments. Part III amendments provide a practical expedient to permit plans to measure investments and investment-related accounts (e.g., a liability for a pending trade with a broker) as of a month-end date that is closest to the plan’s fiscal year-end, when the fiscal period does not coincide with month-end. The amendments in Parts 1 and 2 of this ASU are effective on a retrospective basis and Part 3 is effective on a prospective basis, for fiscal years beginning after December 15, 2015. Early adoption is permitted. The Company is currently assessing the impact that ASU 2015-12 will have on its consolidated financial statements. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date.” The amendments in ASU 2015-14 defer the effective date of ASU 2014-09 for all entities by one year. Public business entities, certain not-for-profit entities, and certain employee benefit plans should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities should apply the guidance in ASU 2014-09 to annual reporting periods beginning after December 15, 2018, and interim reporting periods within annual reporting periods beginning after December 15, 2019. All other entities may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, including interim reporting periods within that reporting period. All other entities also may apply the guidance in ASU 2014-09 earlier as of an annual reporting period beginning after December 15, 2016, and interim reporting periods within annual reporting periods beginning one year after the annual reporting period in which the entity first applies the guidance in ASU 2014-09. The Company does not expect the adoption of ASU 2015-14 (or ASU 2014-09) to have a material impact on its consolidated financial statements. In August 2015, the FASB issued ASU 2015-15, “Interest – Imputation of Interest (Subtopic 835-30) – Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements (Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting).” On April 7, 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires entities to present debt issuance costs related to a recognized debt liability as a direct deduction from the carrying amount of that debt liability. The guidance in ASU 2015-03 (see paragraph 835-30-45-1A) does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff stated that they would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. ASU 2015-15 adds these SEC comments to the “S” section of the Codification. The Company does not expect the adoption of ASU 2015-15 to have a material impact on its consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, “Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments.” The amendments in ASU 2015-16 require that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The amendments require that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the estimated amounts, calculated as if the accounting had been completed at the acquisition date. The amendments also require an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the estimated amounts had been recognized as of the acquisition date. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2016, and interim periods within fiscal years beginning after December 15, 2017. The amendments should be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier application permitted for financial statements that have not been issued. The Company does not expect the adoption of ASU 2015-16 to have a material impact 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 an 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 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.
