Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Note 1. Organization and Summary of Significant Accounting Policies Organization Parkway Acquisition Corp. (“Parkway”) was incorporated as a Virginia corporation on November 2, 2015. Parkway was formed as a business combination shell for the purpose of completing a business combination transaction between Grayson Bankshares, Inc. (“Grayson”) and Cardinal Bankshares Corporation (“Cardinal”). On November 6, 2015, Grayson, Cardinal and Parkway entered into an Agreement and Plan of Merger (the “merger agreement”), providing for the combination of the three companies. Terms of the merger agreement called for Grayson and Cardinal to merge with and into Parkway, with Parkway as the surviving corporation (the “merger”). The merger agreement established exchange ratios under which each share of Grayson common stock was converted to the right to receive 1.76 shares of common stock of Parkway, while each share of Cardinal common stock was converted to the right to receive 1.30 shares of common stock of Parkway. The exchange ratios resulted in Grayson shareholders receiving approximately 60% of the newly issued Parkway shares and Cardinal shareholders receiving approximately 40% of the newly issued Parkway shares. The merger was completed on July 1, 2016. Grayson is considered the acquiror and Cardinal is considered the acquiree in the transaction for accounting purposes. Upon completion of the merger, the Bank of Floyd, a wholly-owned subsidiary of Cardinal, was merged with and into Grayson National Bank (the “Bank’), a wholly-owned subsidiary of Grayson. The Bank was organized under the laws of the United States in 1900 and now serves the Virginia counties of Grayson, Floyd, Carroll, Wythe, Montgomery and Roanoke, and the surrounding areas through seventeen full-service banking offices and one loan production office. Effective March 13, 2017, the Bank changed its name to Skyline National Bank. As an FDIC-insured National Banking Association, the Bank is subject to regulation by the Comptroller of the Currency. Parkway is regulated by the Board of Governors of the Federal Reserve System. For purposes of this quarterly report on Form 10-Q, The consolidated financial statements as of March 31, 2017 and for the periods ended March 31, 2017 and 2016 included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. In the opinion of management, the information furnished in the interim consolidated financial statements reflects all adjustments necessary to present fairly the Company’s consolidated financial position, results of operations, changes in stockholders’ equity and cash flows for such interim periods. Management believes that all interim period adjustments are of a normal recurring nature. These consolidated financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto as of December 31, 2016, included in the Company’s Annual Report on Form 10-K Critical Accounting Policies Management believes the policies with respect to the methodology for the determination of the allowance for loan losses, and asset impairment judgments involve a higher degree of complexity and require management to make difficult and subjective judgments which often require assumptions or estimates about highly uncertain matters. Changes in these judgments, assumptions or estimates could cause reported results to differ materially. These critical policies and their application are periodically reviewed with the Audit Committee and the Board of Directors. Principles of Consolidation The consolidated financial statements include the accounts of the Company and the Bank, which is wholly owned. All significant, intercompany transactions and balances have been eliminated in consolidation. Business Segments The Company reports its activities as a single business segment. In determining the appropriateness of segment definition, the Company considers components of the business about which financial information is available and regularly evaluated relative to resource allocation and performance assessment. Business Combinations Generally, acquisitions are accounted for under the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowances for loan and foreclosed real estate losses, management obtains independent appraisals for significant properties. Substantially all of the Bank’s loan portfolio consists of loans in its market area. Accordingly, the ultimate collectibility of a substantial portion of the Bank’s loan portfolio and the recovery of a substantial portion of the carrying amount of foreclosed real estate are susceptible to changes in local market conditions. The regional economy is diverse, but influenced to an extent by the manufacturing and agricultural segments. While management uses available information to recognize loan and foreclosed real estate losses, future additions to the allowances may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as a part of their routine examination process, periodically review the Bank’s allowances for loan and foreclosed real estate losses. Such agencies may require the Bank to recognize additions to the allowances based on their judgments about information available to them at the time of their examinations. Because of these factors, it is reasonably possible that the allowances for loan and foreclosed real estate losses may change materially in the near term. The Company seeks strategies that minimize the tax effect of implementing their business strategies. As such, judgments are made regarding the ultimate consequence of long-term tax planning strategies, including the likelihood of future recognition of deferred tax benefits. The Company’s tax returns are subject to examination by both Federal and State authorities. Such examinations may result in the assessment of additional taxes, interest and penalties. As a result, the ultimate outcome, and the corresponding financial statement impact, can be difficult to predict with accuracy. Accounting for pension benefits, costs and related liabilities are developed using actuarial valuations. These valuations include key assumptions determined by management, including the discount rate and expected long-term rate of return on plan assets. Material changes in pension costs may occur in the future due to changes in these assumptions. Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents includes cash and amounts due from banks (including cash items in process of collection), interest-bearing deposits with banks and federal funds sold. Trading Securities The Company does not hold securities for short-term resale and therefore does not maintain a trading securities portfolio. Securities Held to Maturity Bonds, notes, and debentures for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. The Company does not currently hold any securities classified as held to maturity. Securities Available for Sale Available for sale securities are reported at fair value and consist of bonds, notes, debentures, and certain equity securities not classified as trading securities or as held to maturity securities. Unrealized holding gains and losses, net of tax, on available for sale securities are reported as a net amount in a separate component of accumulated other comprehensive income. Realized gains and losses on the sale of available for sale securities are determined using the specific-identification method. Premiums and discounts are recognized in interest income using the interest method over the period to maturity. Declines in the fair value of individual held to maturity and available for sale securities below cost that are other than temporary are reflected as write-downs of the individual securities to fair value. Related write-downs are included in earnings as realized losses. Loans Receivable Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off Interest is accrued and credited to income based on the principal amount outstanding. The accrual of interest on impaired loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent cash payments are received. Payments received are first applied to principal, and any remaining funds are then applied to interest. When facts and circumstances indicate the borrower has regained the ability to meet the required payments, the loan is returned to accrual status. Past due status of loans is determined based on contractual terms. Purchased Performing Loans – Purchased Credit-Impaired (“PCI”) Loans Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance, or portion there of, is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component is calculated on an individual basis for larger-balance, non-homogeneous non-impaired A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a restructuring agreement. Troubled Debt Restructurings Under GAAP, the Bank is required to account for certain loan modifications or restructurings as “troubled debt restructurings” or “troubled debt restructured loans.” In general, the modification or restructuring of a debt constitutes a troubled debt restructuring if the Bank for economic or legal reasons related to the borrower’s financial difficulties grants a concession to the borrower that the Bank would not otherwise consider. Debt restructuring or loan modifications for a borrower do not necessarily always constitute a troubled debt restructuring, however, and troubled debt restructurings do not necessarily result in non-accrual Property and Equipment Land is carried at cost. Bank premises, furniture and equipment are carried at cost, less accumulated depreciation and amortization computed principally by the straight-line method over the following estimated useful lives: Years Buildings and improvements 10-40 Furniture and equipment 5-12 Foreclosed Assets Real estate properties acquired through, or in lieu of, loan foreclosure are to be sold and are initially recorded at fair value less anticipated cost to sell at the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed by management and the real estate is carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in foreclosure expense on the consolidated statements of income. Pension Plan Prior to the merger, both Grayson National Bank (Grayson) and Bank of Floyd (Floyd) had qualified noncontributory defined benefit pension plans in place which covered substantially all of each bank’s employees. The benefits in each plan are primarily based on years of service and earnings. Both Grayson and Floyd plans were amended to freeze benefit accruals for all eligible employees prior to the effective date of the merger. Grayson’s plan is a single-employer plan, the funded status of which is measured as the difference between the fair value of plan assets and the projected benefit obligation. Floyd’s plan is a multi-employer plan for accounting purposes and is a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Bank; (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and (3) the Bank does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. Core Deposit Intangible Core deposit intangibles represent the value of long-term deposit relationships acquired in a business combination. Core deposit intangibles are amortized over the estimated useful lives of the deposit accounts acquired (generally twenty years on an accelerated basis). Income Taxes Provision for income taxes is based on amounts reported in the statements of income (after exclusion of non-taxable Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more likely than not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more likely than not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Advertising Expense The Company expenses advertising costs as they are incurred. Advertising expense for the years presented is not material. Basic Earnings per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding during the period, after giving retroactive effect to stock splits and dividends. Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income includes unrealized gains and losses on securities available for sale and changes in the funded status of the pension plan which are also recognized as separate components of equity. The accumulated balances related to each component of other comprehensive income (loss) are as follows: Unrealized Gains (dollars in thousands) On Available for Defined Benefit Total Balance, December 31, 2015 $ (116 ) $ (608 ) $ (724 ) Other comprehensive loss before reclassifications (218 ) (172 ) (390 ) Amounts reclassified from accumulated other comprehensive loss (240 ) — (240 ) Balance December 31, 2016 (574 ) (780 ) (1,354 ) Other comprehensive income before reclassifications 347 — 347 Balance March 31, 2017 $ (227 ) $ (780 ) $ (1,007 ) Off-Balance In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under line of credit arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 8. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates. Reclassification Certain reclassifications have been made to the prior years’ financial statements to place them on a comparable basis with the current presentation. Net income and stockholders’ equity previously reported were not affected by these reclassifications. Recent Accounting Pronouncements The following accounting standards may affect the future financial reporting by the Company: In May 2014, the FASB issued guidance to change the recognition of revenue from contracts with customers. The core principle of the new guidance is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. The guidance will be effective for the Company for annual periods beginning after December 15, 2017, and interim periods within annual reporting periods beginning after December 15, 2018. The Company will apply the guidance using a full retrospective approach. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In August 2015, the FASB deferred the effective date of ASU 2014-09, 2014-09 In November 2015, the FASB amended the Income Taxes topic of the Accounting Standards Codification to simplify the presentation of deferred income taxes by requiring that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments will be effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted as of the beginning of an interim or annual reporting period. The Company will apply the guidance prospectively. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In January 2016, the FASB amended the Financial Instruments topic of the Accounting Standards Codification to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company will apply the guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values will be applied prospectively to equity investments that exist as of the date of adoption of the amendments. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In February 2016, the FASB amended the Leases topic of the Accounting Standards Codification to revise certain aspects of recognition, measurement, presentation, and disclosure of leasing transactions. The amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. In March 2016, the FASB amended the Revenue from Contracts with Customers topic of the Accounting Standards Codification to clarify the implementation guidance on principal versus agent considerations and address how an entity should assess whether it is the principal or the agent in contracts that include three or more parties. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements. In April 2016, the FASB amended the Revenue from Contracts with Customers topic of the Accounting Standards Codification to clarify guidance related to identifying performance obligations and accounting for licenses of intellectual property. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements. In May 2016, the FASB amended the Revenue from Contracts with Customers topic of the Accounting Standards Codification to clarify guidance related to collectability, noncash consideration, presentation of sales tax, and transition. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017 . In June 2016, the FASB issued guidance to change the accounting for credit losses and modify the impairment model for certain debt securities. The amendments will be effective for the Company for reporting periods beginning after December 15, 2019. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. In August 2016, the FASB amended the Statement of Cash Flows topic of the Accounting Standards Codification to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. The Company does not expect these amendments to have a material effect on its financial statements. In October 2016, the FASB amended the Income Taxes topic of the Accounting Standards Codification to modify the accounting for intra-entity transfers of assets other than inventory. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In November 2016, the FASB amended the Statement of Cash Flows topic of the Accounting Standards Codification to clarify how restricted cash is presented and classified in the statement of cash flows. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In December 2016, the FASB issued technical corrections and improvements to the Revenue from Contracts with Customers Topic. These corrections make a limited number of revisions to several pieces of the revenue recognition standard issued in 2014. The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2017. The Company will apply the guidance using a full retrospective approach. The Company does not expect these amendments to have a material effect on its financial statements. In January 2017, the FASB issued guidance to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendment to the Business Combinations Topic is intended to address concerns that the existing definition of a business has been applied too broadly and has resulted in many transactions being recorded as business acquisitions that in substance are more akin to asset acquisitions. The guidance will be effective for the Company for reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In January 2017, the FASB updated the Accounting Changes and Error Corrections and the Investments—Equity Method and Joint Ventures Topics of the Accounting Standards Codification. The ASU incorporates into the Accounting Standards Codification recent SEC guidance about disclosing, under SEC SAB Topic 11.M, the effect on financial statements of adopting the revenue, leases, and credit losses standards. The ASU was effective upon issuance. The Company is currently evaluating the impact on additional disclosure requirements as each of the standards is adopted, however it does not expect these amendments to have a material effect on its financial position, results of operations or cash flows. In January 2017, the FASB amended the Goodwill and Other Topic of the Accounting Standards Codification to simplify the accounting for goodwill impairment for public business entities and other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill. The amendment removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2019 . In February 2017, the FASB amended the Other Income Topic of the Accounting Standards Codification to clarify the scope of the guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. The amendments conform the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements. In March 2017, the FASB amended the requirements in the Compensation—Retirement Benefits Topic of the Accounting Standards Codification related to the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2017 . In March 2017, the FASB amended the requirements in the Receivables—Nonrefundable Fees and Other Costs Topic of the Accounting Standards Codification related to the amortization period for certain purchased callable debt securities held at a premium. The amendments shorten the amortization period for the premium to the earliest call date. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

Business Combinations [Abstract]
Business Combinations	Note 2. Business Combinations On July 1, 2016, Parkway completed its merger with Grayson and Cardinal. Parkway had no material assets or liabilities and did not conduct any business prior to consummation of the merger except to perform its obligations under the merger agreement. As such, Grayson is considered the acquiring entity in this business combination for accounting purposes. Under the terms of the merger agreement, each share of Grayson common stock was converted to the right to receive 1.76 shares of common stock of Parkway, while each share of Cardinal common stock was converted to the right to receive 1.30 shares of common stock of Parkway. There was no trading market and no market price for Parkway common stock on the date of the transaction. Parkway was quoted on the OTC Markets and began trading on August 31, 2016; however, Parkway is a new company and the stock is thinly traded. Grayson, as the accounting acquirer at the time of the merger, was also thinly traded and the limited number of shares traded prior to the acquisition were not considered indicative of trading value. Due to the limited trading history of Parkway and Grayson, the Company engaged a third party to determine the value of the transaction as well as the value of the consideration paid to Cardinal as a result of the transaction. The Company also engaged a third party to calculate fair values of all assets and liabilities acquired in the transaction. These valuations are not final and may be refined for up to one year following the merger date. The following table presents the Cardinal assets acquired and liabilities assumed as of July 1, 2016 as well as the related fair value adjustments and determination of purchase gain. (dollars in thousands) As Reported by Fair Value As Reported by Cardinal Adjustments Parkway Assets Cash and cash equivalents $ 11,698 $ — $ 11,698 Investment securities 59,327 (322 )(a) 59,005 Restricted equity securities 1,308 — 1,308 Loans 164,044 (6,192 )(b) 157,852 Allowance for loan losses (2,123 ) 2,123 (c) — Cash value of life insurance 6,714 — 6,714 Property and equipment 5,384 1,039 (d) 6,423 Intangible assets — 2,469 (e) 2,469 Accrued interest receivable 539 — 539 Other assets 2,450 4,677 (f) 7,127 Total assets acquired $ 249,341 $ 3,794 $ 253,135 Liabilities Deposits $ 218,671 $ 602 (g) $ 219,273 Borrowings 8,000 — (h) 8,000 Accrued interest payable 35 — 35 Other liabilities 1,289 147 (i) 1,436 Total liabilities acquired $ 227,995 $ 749 $ 228,744 Net assets acquired 24,391 Total consideration paid 23,500 Purchase gain $ 891 Explanation of fair value adjustments: (a) Reflects the opening fair value of securities portfolio, which was established as the new book basis of the portfolio. (b) Reflects the fair value adjustment based on the Company’s third party valuation report. (c) Existing allowance for loan losses eliminated to reflect accounting guidance. (d) Estimated adjustment to Cardinal’s real property based upon third-party appraisals and the Company’s evaluation of equipment and other fixed assets. (e) Reflects the recording of the estimated core deposit intangible based on the Company’s third party valuation report. (f) Recording of deferred tax asset generated by the net fair value adjustments (tax rate = 34%). Also recognizes partial reversal of Cardinal’s deferred tax asset valuation allowance. (g) Estimated fair value adjustment to time deposits based on the Company’s third party evaluation report on deposits assumed. (h) Cardinal’s borrowings were overnight borrowings and carried at fair value therefore no adjustment was required. (i) Reflects the fair value adjustment based on the Company’s evaluation of acquired other liabilities. The merger was accounted for under the acquisition method of accounting. The assets and liabilities of Cardinal have been recorded at their estimated fair values and added to those of Grayson for periods following the merger date. Valuations of acquired Cardinal assets and liabilities may be refined for up to one year following the merger date. There are two methods to account for acquired loans as part of a business combination. Acquired loans that contain evidence of credit deterioration on the date of purchase are carried at the net present value of expected future proceeds in accordance with Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 310-30. 310-20. Due to the limited trading history of Parkway and Grayson, the Company engaged a third party to determine the value of the transaction as well as the value of the consideration paid to Cardinal as a result of the transaction. The determined value of consideration received by Cardinal, when compared to the fair value of the net assets acquired from Cardinal, resulted in a bargain purchase gain of $891 thousand for the year ended December 31, 2016. The determined value of consideration received by Cardinal represented a premium when compared to the market price of Parkway stock, which was not publicly traded on the date of the merger. The premium results from enhanced cash flows and a lower required rate of return which are expected to be realized by Parkway, as compared to Grayson or Cardinal on a standalone basis. The merger of Grayson and Cardinal is expected to increase loan revenues due to an increased legal lending limit and expanded market area. Fee income is also expected to increase due to the larger deposit population. Significant cost savings are expected to be realized, particularly in the areas of salaries and benefits, data processing fees, and professional fees. A lower required rate of return is anticipated due to increased access to capital and an expected increase in liquidity of shares due to higher trading volumes. The following table presents the assets and liabilities of Parkway and Grayson prior to the merger, the estimated fair value of Cardinal assets acquired and liabilities assumed, and the resulting estimated balance sheet of Parkway immediately following the merger on July 1, 2016. (dollars in thousands) Pre-Merger Pre-Merger Cardinal Post-Merger Parkway Grayson Acquired Parkway Assets Cash and cash equivalents $ — $ 13,117 $ 11,698 $ 24,815 Investment securities — 33,847 59,005 92,852 Restricted equity securities — 971 1,308 2,279 Loans — 244,800 157,852 402,652 Allowance for loan losses — (3,309 ) — (3,309 ) Cash value of life insurance — 10,122 6,714 16,836 Foreclosed assets — 95 — 95 Property and equipment — 11,548 6,423 17,971 Goodwill and other intangible assets — — 2,469 2,469 Accrued interest receivable — 1,253 539 1,792 Other assets — 5,044 7,127 12,171 Total assets $ — $ 317,488 $ 253,135 $ 570,623 Liabilities Deposits $ — $ 274,265 $ 219,273 $ 493,538 Borrowings — 10,000 8,000 18,000 Accrued interest payable — 96 35 131 Other liabilities — 1,146 1,436 2,582 Total liabilities $ — $ 285,507 $ 228,744 $ 514,251 Stockholders’ Equity $ — $ 31,981 $ 24,391 $ 56,372 Supplemental Pro Forma Information (dollars in thousands except per share data) The table below presents supplemental pro forma information as if the Cardinal acquisition had occurred at the beginning of the earliest period presented, which was January 1, 2016. Pro forma results include adjustments for amortization and accretion of fair value adjustments and do not include any projected cost savings or other anticipated benefits of the merger.

Investment Securities	Note 3. Investment Securities Debt and equity securities have been classified in the consolidated balance sheets according to management’s intent. The amortized cost of securities and their approximate fair values at March 31, 2017 and December 31, 2016 follow: (dollars in thousands) Amortized Unrealized Unrealized Fair Cost Gains Losses Value March 31, 2017 Available for sale: Government sponsored enterprises $ 2,046 $ 167 $ (62 ) $ 2,151 Mortgage-backed securities 35,177 15 (425 ) 34,767 Corporate securities 3,049 — (73 ) 2,976 State and municipal securities 20,658 156 (122 ) 20,692 $ 60,930 $ 338 $ (682 ) $ 60,586 December 31, 2016 Available for sale: Government sponsored enterprises 2,046 236 (73 ) 2,209 Mortgage-backed securities 36,021 4 (823 ) 35,202 Corporate securities 3,061 — (87 ) 2,974 State and municipal securities 22,282 97 (224 ) 22,155 $ 63,410 $ 337 $ (1,207 ) $ 62,540 Restricted equity securities were $1.4 million and $1.1 million at March 31, 2017 and December 31, 2016, respectively. Restricted equity securities consist of investments in stock of the Federal Home Loan Bank of Atlanta (FHLB), Community Bankers Bank, Pacific Coast Bankers Bank, and the Federal Reserve Bank of Richmond, all of which are carried at cost. All of these entities are upstream correspondents of the Bank. The FHLB requires financial institutions to make equity investments in the FHLB in order to borrow money. The Bank is required to hold that stock so long as it borrows from the FHLB. The Federal Reserve requires Banks to purchase stock as a condition for membership in the Federal Reserve System. The Bank’s stock in Community Bankers Bank and Pacific Coast Bankers Bank is restricted only in the fact that the stock may only be repurchased by the respective banks. The following tables details unrealized losses and related fair values in the Company’s held to maturity and available for sale investment securities portfolios. This information is aggregated by the length of time that individual securities have been in a continuous unrealized loss position as of March 31, 2017 and December 31, 2016. Less Than 12 Months 12 Months or More Total (dollars in thousands) Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses March 31, 2017 Available for sale: Government sponsored enterprises $ — $ — $ 1,935 $ (62 ) $ 1,935 $ (62 ) Mortgage-backed securities 29,251 (397 ) 694 (28 ) 29,945 (425 ) Corporate securities 1,546 (3 ) 1,430 (70 ) 2,976 (73 ) State and municipal securities 7,220 (114 ) 1,082 (8 ) 8,302 (122 ) Total securities available for sale $ 38,017 $ (514 ) $ 5,141 $ (168 ) $ 43,158 $ (682 ) December 31, 2016 Available for sale: Government sponsored enterprises — — 1,924 (73 ) 1,924 (73 ) Mortgage-backed securities 31,759 (789 ) 688 (34 ) 32,447 (823 ) Corporate securities 1,548 (12 ) 1,425 (75 ) 2,973 (87 ) State and municipal securities 12,208 (224 ) — — 12,208 (224 ) Total securities available for sale $ 45,515 $ (1,025 ) $ 4,037 $ (182 ) $ 49,552 $ (1,207 ) At March 31, 2017, 35 debt securities with unrealized losses had depreciated 1.58 percent from their amortized cost basis. 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. Consideration is given to the length of time and the extent to which the fair value has been less than cost, and the financial condition and near-term prospects of the issuer. The relative significance of these and other factors will vary on a case by case basis. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, the results of reviews of the issuer’s financial condition and the issuer’s anticipated ability to pay the contractual cash flows of the investments. Since the Company intends to hold all of its investment securities until maturity, and it is more likely than not that the Company will not have to sell any of its investment securities before unrealized losses have been recovered, and the Company expects to recover the entire amount of the amortized cost basis of all its securities, none of the securities are deemed other than temporarily impaired at March 31, 2017. Management continues to monitor all of these securities with a high degree of scrutiny. There can be no assurance that the Company will not conclude in future periods that conditions existing at that time indicate some or all of these securities are other than temporarily impaired, which could require a charge to earnings in such periods. Proceeds from the sale of investment securities available for sale totaled $17.9 million for the three month period ended March 31, 2016. There were no sales of investment securities available for sale for the three month period ended March 31, 2017. Gross realized gains and losses for the three months ended March 31, 2017 and 2016 are as follows: Three Months Ended March 31, (dollars in thousands) 2017 2016 Realized gains $ — $ 365 Realized losses — (4 ) $ — $ 361 There were no securities transferred between the available for sale and held to maturity portfolios or other sales of held to maturity securities during the periods presented. In the future management may elect to classify securities as held to maturity based upon such considerations as the nature of the security, the Bank’s ability to hold the security until maturity, and general economic conditions. The scheduled maturities of securities available for sale at March 31, 2017, were as follows: Amortized Fair (dollars in thousands) Cost Value Due in one year or less $ — $ — Due after one year through five years 11,391 11,344 Due after five years through ten years 22,104 21,932 Due after ten years 27,435 27,310 $ 60,930 $ 60,586 Maturities of mortgage backed securities are based on contractual amounts. Actual maturity will vary as loans underlying the securities are prepaid. Investment securities with amortized cost of approximately $10.1 million and $11.2 million at March 31, 2017 and December 31, 2016, respectively, were pledged as collateral on public deposits and for other purposes as required or permitted by law. and for other purposes as required or permitted by law.

Allowance for Loan Losses and Impaired Loans	Note 5. Allowance for Loan Losses and Impaired Loans Allowance for Loan Losses The allowance for loan losses is maintained at a level believed to be sufficient to provide for estimated loan losses based on evaluating known and inherent risks in the loan portfolio. The allowance is provided based upon management’s comprehensive analysis of the pertinent factors underlying the quality of the loan portfolio. These factors include changes in the amount and composition of the loan portfolio, delinquency levels, actual loss experience, current economic conditions, and detailed analysis of individual loans for which the full collectability may not be assured. The detailed analysis includes methods to estimate the fair value of loan collateral and the existence of potential alternative sources of repayment. The allowance consists of specific and general components. The specific component is calculated on an individual basis for larger-balance, non-homogeneous A provision for loan losses is charged against operations and is added to the allowance for loan losses based on quarterly comprehensive analyses of the loan portfolio. The allowance for loan losses is allocated to certain loan categories based on the relative risk characteristics, asset classifications and actual loss experience of the loan portfolio. While management has allocated the allowance for loan losses to various loan portfolio segments, the allowance is general in nature and is available for the loan portfolio in its entirety. The following table presents activity in the allowance for loan losses by loan category three months ended March 31, 2017 and 2016 and the related asset balances as of March 31, 2017 and December 31, 2016: Allowance for Loan Losses and Recorded Investment in Loans Commercial Construction & Commercial & Consumer (dollars in thousands) Agricultural Mortgage Development Farmland Residential & Other Total For the Three Months Ended March 31, 2017 Allowance for loan losses: Balance, December 31, 2016 $ 210 $ 600 $ 319 $ 342 $ 1,841 $ 108 $ 3,420 Charge-offs — (42 ) — — — (15 ) (57 ) Recoveries 27 — 56 — 15 7 105 Provision (7 ) 86 (26 ) 59 24 (28 ) 108 Balance, March 31, 2017 $ 230 $ 644 $ 349 $ 401 $ 1,880 $ 72 $ 3,576 For the Three Months Ended March 31, 2016 Allowance for loan losses: Balance, December 31, 2015 $ 136 $ 578 $ 344 $ 435 $ 1,887 $ 38 $ 3,418 Charge-offs (19 ) (11 ) — — (22 ) (23 ) (75 ) Recoveries 2 — 35 — 14 5 56 Provision 11 20 (44 ) (32 ) (63 ) 21 (87 ) Balance, March 31, 2016 $ 130 $ 587 $ 335 $ 403 $ 1,816 $ 41 $ 3,312 March 31, 2017 Allowance for loan losses: Ending balance $ 230 $ 644 $ 349 $ 401 $ 1,880 $ 72 $ 3,576 Ending balance: individually evaluated for impairment $ — $ — $ — $ 65 $ 163 $ — $ 228 Ending balance: collectively evaluated for impairment $ 230 $ 644 $ 349 $ 336 $ 1,717 $ 72 $ 3,348 Loans outstanding: Ending balance $ 25,472 $ 124,359 $ 27,977 $ 33,794 $ 190,079 $ 10,688 $ 412,369 Ending balance: individually evaluated for impairment $ — $ 114 $ 388 $ 5,654 $ 1,276 $ — $ 7,432 Ending balance: collectively evaluated for impairment $ 25,472 $ 124,245 $ 27,589 $ 28,140 $ 188,803 $ 10,688 $ 404,937 December 31, 2016 Allowance for loan losses: Ending balance $ 210 $ 600 $ 319 $ 342 $ 1,841 $ 108 $ 3,420 Ending balance: individually evaluated for impairment $ — $ — $ — $ 57 $ 184 $ — $ 241 Ending balance: collectively evaluated for impairment $ 210 $ 600 $ 319 $ 285 $ 1,657 $ 108 $ 3,179 Loans outstanding: Ending balance $ 26,086 $ 128,515 $ 26,464 $ 33,531 $ 187,188 $ 10,184 $ 411,968 Ending balance: individually evaluated for impairment $ — $ 114 $ 580 $ 5,030 $ 1,533 $ — $ 7,257 Ending balance: collectively evaluated for impairment $ 26,086 $ 128,401 $ 25,884 $ 28,501 $ 185,655 $ 10,184 $ 404,711 As of March 31, 2017 and December 31, 2016, the Bank had no unallocated reserves included in the allowance for loan losses. Management closely monitors the quality of the loan portfolio and has established a loan review process designed to help grade the quality of the Bank’s loan portfolio. The Bank’s loan ratings coincide with the “Substandard,” “Doubtful” and “Loss” classifications used by federal regulators in their examination of financial institutions. Generally, an asset is considered Substandard if it is inadequately protected by the current net worth and paying capacity of the obligors and/or the collateral pledged. Substandard assets include those characterized by the distinct possibility that the insured financial institution will sustain some loss if the deficiencies are not corrected. Assets classified as Doubtful have all the weaknesses inherent in assets classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable. Assets classified as Loss are those considered uncollectible, and of such little value that its continuance on the books is not warranted. Assets that do not currently expose the insured financial institutions to sufficient risk to warrant classification in one of the aforementioned categories but otherwise possess weaknesses are designated “Special Mention.” Management also maintains a listing of loans designated “Watch”. These loans represent borrowers with declining earnings, strained cash flow, increasing leverage and/or weakening market fundamentals that indicate above average risk. As of March 31, 2017 and December 31, 2016, respectively, the Bank had no loans graded “Doubtful” or “Loss” included in the balance of total loans outstanding. The following table lists the loan grades utilized by the Bank and the corresponding total of outstanding loans in each category as of March 31, 2017 and December 31, 2016: Credit Risk Profile by Internally Assigned Grades Loan Grades Special (dollars in thousands) Pass Watch Mention Substandard Total March 31, 2017 Real Estate Secured: 1-4 $ 4,496 $ 102 $ — $ — $ 4,598 Commercial construction 3,776 125 — — 3,901 Land development & other land 18,242 356 — 880 19,478 Farmland 23,385 4,723 659 5,027 33,794 1-4 123,814 11,954 — 2,300 138,068 Multifamily 26,038 1,313 — — 27,351 Home equity and second mortgage 23,341 1,210 — 109 24,660 Commercial mortgage 102,446 13,136 3,086 5,691 124,359 Non-Real Commercial & agricultural 22,673 2,219 431 149 25,472 Civic organizations 3,928 — — — 3,928 Consumer-auto 1,588 19 — — 1,607 Consumer-other 5,017 131 — 5 5,153 Total $ 358,744 $ 35,288 $ 4,176 $ 14,161 $ 412,369 Loan Grades Special (dollars in thousands) Pass Watch Mention Substandard Total December 31, 2016 Real Estate Secured: 1-4 $ 4,056 $ 370 $ — $ — $ 4,426 Commercial construction 2,603 — — — 2,603 Land development & other land 18,000 532 — 903 19,435 Farmland 23,201 5,276 — 5,054 33,531 1-4 122,301 11,517 — 2,111 135,929 Multifamily 25,365 1,321 — — 26,686 Home equity and second mortgage 23,219 1,243 — 111 24,573 Commercial mortgage 105,317 13,449 3,353 6,396 128,515 Non-Real Commercial & agricultural 22,719 2,333 485 549 26,086 Civic organizations 3,603 — — — 3,603 Consumer-auto 1,400 21 — — 1,421 Consumer-other 5,015 105 — 40 5,160 Total $ 356,799 $ 36,167 $ 3,838 $ 15,164 $ 411,968 Loans may be placed in nonaccrual status when, in management’s opinion, the borrower may be unable to meet payments as they become due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent cash payments are received. Payments received are first applied to principal, and any remaining funds are then applied to interest. Loans are removed from nonaccrual status when they are deemed a loss and charged to the allowance, transferred to foreclosed assets, or returned to accrual status based upon performance consistent with the original terms of the loan or a subsequent restructuring thereof.

Smaller balance homogenous loans may be collectively evaluated for impairment. Non-homogenous As of March 31, 2017 and December 31, 2016, respectively, the recorded investment in impaired loans totaled $13.9 million and $13.3 million. The total amount of collateral-dependent impaired loans at March 31, 2017 and December 31, 2016, respectively, was $4.4 million and $4.0 million. As of March 31, 2017 and December 31, 2016, respectively, $4.5 million and $4.4 million of the recorded investment in impaired loans did not have a related allowance. The Bank had $10.0 million and $10.0 million in troubled debt restructured loans included in impaired loans at March 31, 2017 and December 31, 2016, respectively. The categories of non-accrual non-accrual In 2015, management began collectively evaluating performing TDRs with a loan balance of $250,000 or less for impairment.

Commitments and Contingencies	Note 7. Commitments and Contingencies Litigation In the normal course of business the Bank is involved in various legal proceedings. After consultation with legal counsel, management believes that any liability resulting from such proceedings will not be material to the consolidated financial statements. Financial Instruments with Off-Balance The Bank is party to financial instruments with off-balance The Bank’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as for on-balance March 31, December 31, (dollars in thousands) 2017 2016 Commitments to extend credit $ 42,486 $ 54,667 Standby letters of credit 1,066 — $ 43,552 $ 54,667 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case Standby letters of credit are conditional commitments issued by the Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Collateral held varies as specified above and is required in instances which the Bank deems necessary. Concentrations of Credit Risk Substantially all of the Bank’s loans, commitments to extend credit, and standby letters of credit have been granted to customers in the Bank’s market area and such customers are generally depositors of the Bank. Investments in state and municipal securities involve governmental entities within and outside the Bank’s market area. The concentrations of credit by type of loan are set forth in Note 5. The distribution of commitments to extend credit approximates the distribution of loans outstanding. Standby letters of credit are granted primarily to commercial borrowers. The Bank’s primary focus is toward small business and consumer transactions, and accordingly, it does not have a significant number of credits to any single borrower or group of related borrowers in excess of $5,000,000. The Bank has cash and cash equivalents on deposit with financial institutions which exceed federally insured limits.

Financial Instruments

Investments, All Other Investments [Abstract]
Financial Instruments	Note 8. Financial Instruments FASB ASC 825, “Financial Instruments”, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet. In cases where quoted market prices are not available, fair values are based on estimates using present value of future cash flows or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. FASB ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. The following presents the carrying amount, fair value, and placement in the fair value hierarchy of the Company’s financial instruments as of March 31, 2017 and December 31, 2016. This table excludes financial instruments for which the carrying amount approximates fair value. For short-term financial assets such as cash and cash equivalents, the carrying amount is a reasonable estimate of fair value due to the relatively short time between the origination of the instrument and its expected realization. For financial liabilities such as noninterest-bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity. Fair Value Measurements (dollars in thousands) Carrying Fair Value Quoted Prices in Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) March 31, 2017 Financial Instruments - Assets Net Loans $ 408,793 $ 406,345 $ — $ 405,638 $ 707 Financial Instruments – Liabilities Time Deposits 166,967 164,626 — 164,626 — December 31, 2016 Financial Instruments - Assets Net Loans $ 408,548 $ 405,876 $ — $ 405,410 $ 466 Financial Instruments – Liabilities Time Deposits 167,355 165,257 — 165,257 — The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available for sale and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as loans or foreclosed assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Fair Value Hierarchy Under FASB ASC 820, “Fair Value Measurements and Disclosures”, the Company groups assets and liabilities 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. These levels are: Level 1 – Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 – Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include the use of option pricing models, discounted cash flow models and similar techniques. Following is a description of valuation methodologies used for assets and liabilities recorded at fair value. Investment Securities Available for Sale Investment securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter Loans The Company does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. If a loan is identified as individually impaired, management measures impairment in accordance with applicable accounting guidance. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value, and discounted cash flows. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. At December 31, 2016, a small percentage of the total impaired loans were evaluated based on the fair value of the collateral. In accordance with accounting standards, impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price the Company records the impaired loan as nonrecurring Level 2. When the fair value is based on either an external or internal appraisal and there is no observable market price, the Company records the impaired loan as nonrecurring Level 3. Foreclosed Assets Foreclosed assets are adjusted to fair value upon transfer of the loans to foreclosed assets. Subsequently, foreclosed assets are carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price the Company records the foreclosed asset as nonrecurring Level 2. When the fair value of the collateral is based on either an external or internal appraisal and there is no observable market price, the Company records the foreclosed asset as nonrecurring Level 3.

Assets Recorded at Fair Value on a Nonrecurring Basis The Company may be required, from time to time, to measure certain assets and liabilities at fair value on a nonrecurring basis in accordance with U.S. generally accepted accounting principles. These include assets and liabilities that are measured at the lower of cost or market that were recognized at fair value below cost at the end of the period. No liabilities were recorded at fair value on a nonrecurring basis at March 31, 2017 and December 31, 2016. Assets measured at fair value on a nonrecurring basis are included in the table below.

	Mar. 31, 2017
Accounting Policies [Abstract]
Critical Accounting Policies	Critical Accounting Policies Management believes the policies with respect to the methodology for the determination of the allowance for loan losses, and asset impairment judgments involve a higher degree of complexity and require management to make difficult and subjective judgments which often require assumptions or estimates about highly uncertain matters. Changes in these judgments, assumptions or estimates could cause reported results to differ materially. These critical policies and their application are periodically reviewed with the Audit Committee and the Board of Directors.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and the Bank, which is wholly owned. All significant, intercompany transactions and balances have been eliminated in consolidation.
Business Segments	Business Segments The Company reports its activities as a single business segment. In determining the appropriateness of segment definition, the Company considers components of the business about which financial information is available and regularly evaluated relative to resource allocation and performance assessment.
Business Combinations	Business Combinations Generally, acquisitions are accounted for under the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses and the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans. In connection with the determination of the allowances for loan and foreclosed real estate losses, management obtains independent appraisals for significant properties. Substantially all of the Bank’s loan portfolio consists of loans in its market area. Accordingly, the ultimate collectibility of a substantial portion of the Bank’s loan portfolio and the recovery of a substantial portion of the carrying amount of foreclosed real estate are susceptible to changes in local market conditions. The regional economy is diverse, but influenced to an extent by the manufacturing and agricultural segments. While management uses available information to recognize loan and foreclosed real estate losses, future additions to the allowances may be necessary based on changes in local economic conditions. In addition, regulatory agencies, as a part of their routine examination process, periodically review the Bank’s allowances for loan and foreclosed real estate losses. Such agencies may require the Bank to recognize additions to the allowances based on their judgments about information available to them at the time of their examinations. Because of these factors, it is reasonably possible that the allowances for loan and foreclosed real estate losses may change materially in the near term. The Company seeks strategies that minimize the tax effect of implementing their business strategies. As such, judgments are made regarding the ultimate consequence of long-term tax planning strategies, including the likelihood of future recognition of deferred tax benefits. The Company’s tax returns are subject to examination by both Federal and State authorities. Such examinations may result in the assessment of additional taxes, interest and penalties. As a result, the ultimate outcome, and the corresponding financial statement impact, can be difficult to predict with accuracy. Accounting for pension benefits, costs and related liabilities are developed using actuarial valuations. These valuations include key assumptions determined by management, including the discount rate and expected long-term rate of return on plan assets. Material changes in pension costs may occur in the future due to changes in these assumptions.
Cash and Cash Equivalents	Cash and Cash Equivalents For purposes of reporting cash flows, cash and cash equivalents includes cash and amounts due from banks (including cash items in process of collection), interest-bearing deposits with banks and federal funds sold.
Trading Securities	Trading Securities The Company does not hold securities for short-term resale and therefore does not maintain a trading securities portfolio.
Securities Held to Maturity	Securities Held to Maturity Bonds, notes, and debentures for which the Company has the positive intent and ability to hold to maturity are reported at cost, adjusted for premiums and discounts that are recognized in interest income using the interest method over the period to maturity. The Company does not currently hold any securities classified as held to maturity.
Securities Available for Sale	Securities Available for Sale Available for sale securities are reported at fair value and consist of bonds, notes, debentures, and certain equity securities not classified as trading securities or as held to maturity securities. Unrealized holding gains and losses, net of tax, on available for sale securities are reported as a net amount in a separate component of accumulated other comprehensive income. Realized gains and losses on the sale of available for sale securities are determined using the specific-identification method. Premiums and discounts are recognized in interest income using the interest method over the period to maturity. Declines in the fair value of individual held to maturity and available for sale securities below cost that are other than temporary are reflected as write-downs of the individual securities to fair value. Related write-downs are included in earnings as realized losses.
Loans Receivable	Loans Receivable Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off Interest is accrued and credited to income based on the principal amount outstanding. The accrual of interest on impaired loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent cash payments are received. Payments received are first applied to principal, and any remaining funds are then applied to interest. When facts and circumstances indicate the borrower has regained the ability to meet the required payments, the loan is returned to accrual status. Past due status of loans is determined based on contractual terms. Purchased Performing Loans – Purchased Credit-Impaired (“PCI”) Loans
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance, or portion there of, is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectibility of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific, general and unallocated components. The specific component is calculated on an individual basis for larger-balance, non-homogeneous non-impaired A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank does not separately identify individual consumer and residential loans for impairment disclosures, unless such loans are the subject of a restructuring agreement.
Troubled Debt Restructurings	Troubled Debt Restructurings Under GAAP, the Bank is required to account for certain loan modifications or restructurings as “troubled debt restructurings” or “troubled debt restructured loans.” In general, the modification or restructuring of a debt constitutes a troubled debt restructuring if the Bank for economic or legal reasons related to the borrower’s financial difficulties grants a concession to the borrower that the Bank would not otherwise consider. Debt restructuring or loan modifications for a borrower do not necessarily always constitute a troubled debt restructuring, however, and troubled debt restructurings do not necessarily result in non-accrual
Property and Equipment	Property and Equipment Land is carried at cost. Bank premises, furniture and equipment are carried at cost, less accumulated depreciation and amortization computed principally by the straight-line method over the following estimated useful lives: Years Buildings and improvements 10-40 Furniture and equipment 5-12
Foreclosed Assets	Foreclosed Assets Real estate properties acquired through, or in lieu of, loan foreclosure are to be sold and are initially recorded at fair value less anticipated cost to sell at the date of foreclosure, establishing a new cost basis. After foreclosure, valuations are periodically performed by management and the real estate is carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in foreclosure expense on the consolidated statements of income.
Pension Plan	Pension Plan Prior to the merger, both Grayson National Bank (Grayson) and Bank of Floyd (Floyd) had qualified noncontributory defined benefit pension plans in place which covered substantially all of each bank’s employees. The benefits in each plan are primarily based on years of service and earnings. Both Grayson and Floyd plans were amended to freeze benefit accruals for all eligible employees prior to the effective date of the merger. Grayson’s plan is a single-employer plan, the funded status of which is measured as the difference between the fair value of plan assets and the projected benefit obligation. Floyd’s plan is a multi-employer plan for accounting purposes and is a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Bank; (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets; and (3) the Bank does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Core Deposit Intangible	Core Deposit Intangible Core deposit intangibles represent the value of long-term deposit relationships acquired in a business combination. Core deposit intangibles are amortized over the estimated useful lives of the deposit accounts acquired (generally twenty years on an accelerated basis).
Income Taxes	Income Taxes Provision for income taxes is based on amounts reported in the statements of income (after exclusion of non-taxable Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more likely than not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more likely than not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized.
Advertising Expense	Advertising Expense The Company expenses advertising costs as they are incurred. Advertising expense for the years presented is not material.
Basic Earnings per Share	Basic Earnings per Share Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding during the period, after giving retroactive effect to stock splits and dividends.
Comprehensive Income	Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income includes unrealized gains and losses on securities available for sale and changes in the funded status of the pension plan which are also recognized as separate components of equity. The accumulated balances related to each component of other comprehensive income (loss) are as follows: Unrealized Gains (dollars in thousands) On Available for Defined Benefit Total Balance, December 31, 2015 $ (116 ) $ (608 ) $ (724 ) Other comprehensive loss before reclassifications (218 ) (172 ) (390 ) Amounts reclassified from accumulated other comprehensive loss (240 ) — (240 ) Balance December 31, 2016 (574 ) (780 ) (1,354 ) Other comprehensive income before reclassifications 347 — 347 Balance March 31, 2017 $ (227 ) $ (780 ) $ (1,007 )
Off-Balance Sheet Credit Related Financial Instruments	Off-Balance In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under line of credit arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 8. Fair value estimates involve uncertainties and matters of significant judgment. Changes in assumptions or in market conditions could significantly affect the estimates.
Reclassification	Reclassification Certain reclassifications have been made to the prior years’ financial statements to place them on a comparable basis with the current presentation. Net income and stockholders’ equity previously reported were not affected by these reclassifications.
Recent Accounting Pronouncements	Recent Accounting Pronouncements The following accounting standards may affect the future financial reporting by the Company: In May 2014, the FASB issued guidance to change the recognition of revenue from contracts with customers. The core principle of the new guidance is that an entity should recognize revenue to reflect the transfer of goods and services to customers in an amount equal to the consideration the entity receives or expects to receive. The guidance will be effective for the Company for annual periods beginning after December 15, 2017, and interim periods within annual reporting periods beginning after December 15, 2018. The Company will apply the guidance using a full retrospective approach. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In August 2015, the FASB deferred the effective date of ASU 2014-09, 2014-09 In November 2015, the FASB amended the Income Taxes topic of the Accounting Standards Codification to simplify the presentation of deferred income taxes by requiring that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments will be effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted as of the beginning of an interim or annual reporting period. The Company will apply the guidance prospectively. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In January 2016, the FASB amended the Financial Instruments topic of the Accounting Standards Codification to address certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company will apply the guidance by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values will be applied prospectively to equity investments that exist as of the date of adoption of the amendments. The Company does not expect these amendments to have a material effect on its consolidated financial statements. In February 2016, the FASB amended the Leases topic of the Accounting Standards Codification to revise certain aspects of recognition, measurement, presentation, and disclosure of leasing transactions. The amendments will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. In March 2016, the FASB amended the Revenue from Contracts with Customers topic of the Accounting Standards Codification to clarify the implementation guidance on principal versus agent considerations and address how an entity should assess whether it is the principal or the agent in contracts that include three or more parties. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements. In April 2016, the FASB amended the Revenue from Contracts with Customers topic of the Accounting Standards Codification to clarify guidance related to identifying performance obligations and accounting for licenses of intellectual property. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements. In May 2016, the FASB amended the Revenue from Contracts with Customers topic of the Accounting Standards Codification to clarify guidance related to collectability, noncash consideration, presentation of sales tax, and transition. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017 . In June 2016, the FASB issued guidance to change the accounting for credit losses and modify the impairment model for certain debt securities. The amendments will be effective for the Company for reporting periods beginning after December 15, 2019. The Company is currently evaluating the effect that implementation of the new standard will have on its financial position, results of operations, and cash flows. In August 2016, the FASB amended the Statement of Cash Flows topic of the Accounting Standards Codification to clarify how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. The Company does not expect these amendments to have a material effect on its financial statements. In October 2016, the FASB amended the Income Taxes topic of the Accounting Standards Codification to modify the accounting for intra-entity transfers of assets other than inventory. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In November 2016, the FASB amended the Statement of Cash Flows topic of the Accounting Standards Codification to clarify how restricted cash is presented and classified in the statement of cash flows. The amendments will be effective for the Company for fiscal years beginning after December 15, 2017 including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In December 2016, the FASB issued technical corrections and improvements to the Revenue from Contracts with Customers Topic. These corrections make a limited number of revisions to several pieces of the revenue recognition standard issued in 2014. The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2017. The Company will apply the guidance using a full retrospective approach. The Company does not expect these amendments to have a material effect on its financial statements. In January 2017, the FASB issued guidance to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendment to the Business Combinations Topic is intended to address concerns that the existing definition of a business has been applied too broadly and has resulted in many transactions being recorded as business acquisitions that in substance are more akin to asset acquisitions. The guidance will be effective for the Company for reporting periods beginning after December 15, 2017. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In January 2017, the FASB updated the Accounting Changes and Error Corrections and the Investments—Equity Method and Joint Ventures Topics of the Accounting Standards Codification. The ASU incorporates into the Accounting Standards Codification recent SEC guidance about disclosing, under SEC SAB Topic 11.M, the effect on financial statements of adopting the revenue, leases, and credit losses standards. The ASU was effective upon issuance. The Company is currently evaluating the impact on additional disclosure requirements as each of the standards is adopted, however it does not expect these amendments to have a material effect on its financial position, results of operations or cash flows. In January 2017, the FASB amended the Goodwill and Other Topic of the Accounting Standards Codification to simplify the accounting for goodwill impairment for public business entities and other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill. The amendment removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The effective date and transition requirements for the technical corrections will be effective for the Company for reporting periods beginning after December 15, 2019 . In February 2017, the FASB amended the Other Income Topic of the Accounting Standards Codification to clarify the scope of the guidance on nonfinancial asset derecognition as well as the accounting for partial sales of nonfinancial assets. The amendments conform the derecognition guidance on nonfinancial assets with the model for transactions in the new revenue standard. The amendments will be effective for the Company for reporting periods beginning after December 15, 2017. The Company does not expect these amendments to have a material effect on its financial statements. In March 2017, the FASB amended the requirements in the Compensation—Retirement Benefits Topic of the Accounting Standards Codification related to the income statement presentation of the components of net periodic benefit cost for an entity’s sponsored defined benefit pension and other postretirement plans. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2017 . In March 2017, the FASB amended the requirements in the Receivables—Nonrefundable Fees and Other Costs Topic of the Accounting Standards Codification related to the amortization period for certain purchased callable debt securities held at a premium. The amendments shorten the amortization period for the premium to the earliest call date. The amendments will be effective for the Company for interim and annual periods beginning after December 15, 2018. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies are not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

This table excludes financial instruments for which the carrying amount approximates fair value.

For financial liabilities such as noninterest-bearing demand, interest-bearing demand, and savings deposits, the carrying amount is a reasonable estimate of fair value due to these products having no stated maturity.
