Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Note 1. Organization and Summary of Significant Accounting Policies Organization Parkway Acquisition Corp. (“Parkway” or the “Company”) was incorporated as a Virginia corporation on November 2, 2015. Parkway was formed as a business combination shell company 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 pursuant to which Grayson and Cardinal merged with and into Parkway, with Parkway as the surviving corporation (the “Cardinal 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 Cardinal merger was completed on July 1, 2016. Grayson was considered the acquiror and Cardinal was considered the acquiree in the transaction for accounting purposes. Upon completion of the Cardinal 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. Effective March 13, 2017, the Bank changed its name to Skyline National Bank. On March 1, 2018, Parkway entered into a definitive agreement pursuant to which Parkway acquired Great State Bank (“Great State”), based in Wilkesboro, North Carolina. The agreement provided for the merger of Great State with and into the Bank, with the Bank as the surviving bank (the “Great State merger”). The transaction closed and the merger became effective on July 1, 2018. Each share of Great State common stock was converted into the right to receive 1.21 shares of Parkway common stock. The Company issued 1,191,899 shares and recognized $15.5 million in surplus in the Great State merger. Parkway was considered the acquiror and Great State was considered the acquiree in the transaction for accounting 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 North Carolina counties of Alleghany, Ashe, Burke, Caldwell, Catawba, Cleveland, Watauga, Wilkes, and Yadkin, and the surrounding areas through twenty full-service banking offices and four loan production offices. As an FDIC-insured national banking association, the Bank is subject to regulation by the Comptroller of the Currency and the FDIC. Parkway is regulated by the Board of Governors of the Federal Reserve System. 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. A business combination occurs when the Company acquires net assets that constitute a business, or acquires equity interests in one or more other entities that are businesses and obtains control over those entities. Business combinations are effected through the transfer of consideration consisting of cash and/or common stock and are accounted for using the acquisition method. Accordingly, the assets and liabilities of the acquired entity are recorded at their respective fair values as of the closing date of the acquisition. Determining the fair value of assets and liabilities, especially the loan portfolio, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values. Fair values are subject to refinement for up to one year after the closing date of the acquisition as information relative to closing date fair values becomes available. The results of operations of an acquired entity are included in our consolidated results from the closing date of the merger, and prior periods are not restated. No allowance for loan losses related to the acquired loans is recorded on the acquisition date because the fair value of the loans acquired incorporates assumptions regarding future credit losses. The fair value estimates associated with the acquired loans include estimates related to expected prepayments and the amount and timing of expected principal, interest and other cash flows. 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 collectability 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 are reported at their outstanding principal amount adjusted for any charge-offs and the allowance for loan losses. Loan origination costs are capitalized and recognized as an adjustment to yield over the life of the related loan. 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 with evidence of credit deterioration since origination, and for which it is probable that all contractually required payments will not be collected, are considered credit impaired. Evidence of credit quality deterioration as of the purchase date may include statistics such as internal risk grade and past due and nonaccrual status. Purchased impaired loans generally meet the Company’s definition for nonaccrual status. PCI loans are initially measured at fair value, which reflects estimated future credit losses expected to be incurred over the life of the loan. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference, and is available to absorb credit losses on those loans. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent significant increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges, or a reclassification of the nonaccretable difference with a positive impact on future interest income. 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 thereof, 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 collectability 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 loans, which are considered impaired. A specific allowance is established when the discounted cash flows, collateral value (less disposal costs), or observable market price of the impaired loan is lower than its carrying value. The specific component of the allowance for smaller-balance loans whose terms have been modified in a troubled debt restructuring (TDR) is calculated on a pooled basis considering historical experience adjusted for qualitative factors. The general component covers non-impaired loans and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. 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 basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for all loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. 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 loans. 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 Cardinal 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 Cardinal 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. Goodwill and Other Intangible Assets Goodwill arises from business combinations and is generally determined as the excess of fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquire, over the fair value of the nets assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently in events and circumstances exists that indicate that a goodwill impairment test should be performed. The Company has selected July 1, 2019 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consist of core deposit intangibles that 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 Revenue Recognition On January 1, 2018, we adopted the requirements of Accounting Standards Update (“ASU”) 2014-9, Revenue from Contracts with Customers (“ASU Topic 606”) . The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. Based on this assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. The Company also completed its evaluation of certain costs related to these revenue streams to determine whether such costs should be presented as expenses or contra-revenue (i.e., gross vs. net). Based on its evaluation, the Company determined that ASU 2014-09 did not materially change the method in which the Company currently classifies certain costs associated with the related revenue streams. The Company adopted ASU 2014-09 and its related amendments on its required effective date of January 1, 2018 utilizing the modified retrospective approach. Since there was no net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not deemed necessary. Income Taxes Provision for income taxes is based on amounts reported in the statements of income (after exclusion of non-taxable income such as interest on state and municipal securities) and consists of taxes currently due plus deferred taxes on temporary differences in the recognition of income and expense for tax and financial statement purposes. Deferred tax assets and liabilities are included in the financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. 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. The Company has early adopted ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” which is considered a change in accounting principle. Because the required adjustment of deferred taxes is required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (commonly referred to as “stranded” tax effects) would not reflect the appropriate tax rate. Adoption of this ASU eliminates the “stranded” tax effects associated with the change in the federal corporate income tax rate in the Tax Cuts and Jobs Act of 2017. The Company has reclassified “stranded” tax effects totaling $248 thousand from accumulated other comprehensive loss to retained earnings and these reclassified amounts are reflected in the accompanying consolidated statements of changes in stockholders’ equity. Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) 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: (dollars in thousands) Unrealized Gains And Losses On Available for Sale Securities Defined Benefit Pension Items Total Balance, December 31, 2016 $ (574 ) $ (780 ) $ (1,354 ) Other comprehensive income (loss) before reclassifications 296 (44 ) 252 Amounts reclassified from accumulated other comprehensive loss (160 ) — (160 ) Amounts reclassified to retained earnings from other comprehensive loss due to tax rate change (85 ) (163 ) (248 ) Balance, December 31, 2017 $ (523 ) $ (987 ) $ (1,510 ) Balance, December 31, 2017 $ (523 ) $ (987 ) $ (1,510 ) Other comprehensive income (loss) before reclassifications (402 ) (51 ) (453 ) Amounts reclassified from accumulated other comprehensive loss (4 ) — (4 ) Balance, December 31, 2018 $ (929 ) $ (1,038 ) $ (1,967 ) 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. Off-Balance Sheet Credit Related Financial Instruments 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 13. 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 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. We expect to adopt the guidance using the modified retrospective method and practical expedients for transition. The practical expedients allow us to largely account for our existing leases consistent with current guidance except for the incremental balance sheet recognition for lessees. We have performed an evaluation of our leasing contracts and activities. We have developed our methodology to estimate the right-of use assets and lease liabilities, which is based on the present value of lease payments. At December 31, 2018 future minimum lease payments were approximately $334 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. Early adoption is permitted for all organizations for periods beginning after December 15, 2018. The Company will apply the amendments to the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. While early adoption is permitted beginning in first quarter 2019, we do not expect to elect that option. We are evaluating the impact of the ASU on our consolidated financial statements. We expect the ASU will result in an increase in the recorded allowance for loan losses given the change to estimated losses over the contractual life of the loans adjusted for expected prepayments. The majority of the increase results from longer duration portfolios. In addition to our allowance for loan losses, we will also record an allowance for credit losses on debt securities instead of applying the impairment model currently utilized. The amount of the adjustments will be impacted by each portfolio’s composition and credit quality at the adoption date as well as economic conditions and forecasts at that time. 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 . Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 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 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. In February 2018, the FASB amended the Financial Instruments Topic of the Accounting Standards Codification. The amendments clarify certain aspects of the guidance issued in ASU 2016-01. The amendments are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. All entities may early adopt these amendments for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, as long as they have adopted ASU 2016-01. The Company does not expect these amendments to have a material effect on its financial statements. In March 2018, the FASB updated the Debt Securities and the Regulated Op

Business Combinations [Abstract]
Business Combinations	Note 2. Business Combinations On July 1, 2018, Parkway completed its merger with Great State as discussed above in Note 1. Parkway is considered the acquiring entity in this business combination for accounting purposes. Under the terms of the merger agreement, each share of Great State common stock was converted to 1.21 shares of common stock of Parkway which resulted in the issuance of 1,191,899 shares of Parkway stock in the merger. The Company 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 Great State assets acquired and liabilities assumed as of July 1, 2018 as well as the related fair value adjustments and determination of goodwill. (dollars in thousands) As Reported by Fair Value As Reported by Assets Cash and cash equivalents $ 25,761 $ — — $ 25,761 Investment securities 19,630 (229 ) (a) 19,401 Restricted equity securities 523 — — 523 Loans 97,549 (2,441 ) (b) 95,108 Allowance for loan losses (1,436 ) 1,436 (c) — Property and equipment 1,207 189 (d) 1,396 Intangible assets — 2,425 (e) 2,425 Accrued interest receivable 334 — — 334 Other assets 599 (92 ) (f) 507 Total assets acquired $ 144,167 $ 1,288 $ 145,455 Liabilities Deposits $ 129,611 $ 940 (g) $ 130,551 Borrowings 2,000 — — 2,000 Accrued interest payable 40 — — 40 Other liabilities 352 17 (h) 369 Total liabilities acquired $ 132,003 $ 957 $ 132,960 Net assets acquired 12,495 Elimination of Company’s existing investment in Great State 198 Stock consideration 15,495 Goodwill $ 3,198 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 Great State’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 = 21%). (g) Estimated fair value adjustment to time deposits based on the Company’s third party valuation report on deposits assumed. (h) 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 Great State have been recorded at their estimated fair values and added to those of Parkway for periods following the merger date. Valuations of acquired Great State 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 FASB ASC 310-30. All other acquired loans are recorded at their initial fair value, adjusted for subsequent advances, pay downs, amortization or accretion of any premium or discount on purchase, charge-offs and any other adjustment to carrying value in accordance with ASC 310-20. In determining the fair values of acquired loans without evidence of credit deterioration at the date of acquisition, management includes (i) no carryover of any previously recorded allowance for loan losses and (ii) an adjustment of the unpaid principal balance to reflect an appropriate market rate of interest, given the risk profile and grade assigned to each loan. This adjustment is then accreted into earnings as a yield adjustment, using the effective yield method, over the remaining life of each loan. To the extent that current information indicates it is probable that the Company will collect all amounts according to the contractual terms thereof, such loan is not considered impaired and is not considered in the determination of the required allowance for loan losses. To the extent that current information indicates it is probable that the Company will not be able to collect all amounts according to the contractual terms thereon, such loan is considered impaired and is considered in the determination of the required level of allowance for loan and lease losses. Subsequent to the acquisition date, increases in cash flows expected to be received in excess of the Company’s initial estimates are reclassified from nonaccretable difference to accretable yield and are accreted into interest income on a level-yield basis over the remaining life of the loan. Decreases in cash flows expected to be collected are recognized as impairment through the provision for loan losses. Supplemental Pro Forma Information (dollars in thousands except per share data) The table below presents supplemental pro forma information as if the Great State acquisition had occurred at the beginning of the earliest period presented, which was January 1, 2017. 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. Therefore, the pro forma financial information is not indicative of the results of operations that would have occurred had the transactions been effected on the assumed date. Pre-tax merger-related costs of $2.0 million and $748 thousand are included in the Company’s consolidated statements of income for the years ended December 31, 2018 and 2017 and are not included in the pro forma statements below. Year Ended December 31, 2018 2017 (Unaudited) (Unaudited) Net interest income $ 23,956 $ 21,279 Net income (a) $ 4,266 $ 2,743 Basic and diluted weighted average shares outstanding (b) 6,213,275 6,213,275 Basic and diluted earnings per common share $ 0.69 $ 0.44 (a) Supplemental pro forma net income includes the impact of certain fair value adjustments. Supplemental pro forma net income does not include assumptions on cost savings or the impact of merger-related expenses. (b) Weighted average shares outstanding includes the full effect of the common stock issued in connection with the Great State acquisition as of the earliest reporting date. It is impractical to disclose the net interest income, non-interest income, and net income of Great State from the acquisition date of July 1, 2018 through December 31, 2018 due to the system conversion that occurred on September 7, 2018, which resulted in the combining of the operations of Great State into Parkway.

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 December 31, 2018. 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 sales of investment securities available for sale were $18.4 and $8.7 million for the years ended December 31, 2018 and 2017, respectively. Gross realized gains and losses for the years ended December 31 are as follows: (dollars in thousands) 2018 2017 Realized gains $ 9 $ 257 Realized losses (4 ) (15 ) $ 5 $ 242 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 December 31, 2018, were as follows: (dollars in thousands) Amortized Cost Fair Value Due in one year or less $ 703 $ 701 Due after one year through five years 15,030 14,766 Due after five years through ten years 15,571 14,943 Due after ten years 15,301 15,018 $ 46,605 $ 45,428 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 $13.9 million and $11.2 million at December 31, 2018 and 2017 respectively, were pledged as collateral on public deposits and for other purposes as required or permitted by law.

Allowance for Loan Losses and Impaired Loans	Note 6. 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 loans, which are considered impaired. A specific allowance is established when the discounted cash flows, collateral value (less disposal costs), or observable market price of the impaired loan is lower than its carrying value. The specific component of the allowance for smaller-balance loans whose terms have been modified in a troubled debt restructuring (TDR) is calculated on a pooled basis considering historical experience adjusted for qualitative factors. These smaller-balance TDRs were collectively evaluated for impairment. The general component covers the remaining loan portfolio, and is based on historical loss experience adjusted for qualitative factors. The appropriateness of the allowance for loan losses on loans is estimated based upon these factors and trends identified by management at the time financial statements are prepared. 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 by loan category and information on the loans evaluated individually for impairment and collectively evaluated for impairment as of December 31, 2018 and December 31, 2017: Allowance for Loan Losses and Recorded Investment in Loans (dollars in thousands) Construction & Development Farmland Residential Commercial Mortgage Commercial & Agricultural Consumer & Other Total December 31, 2018 Allowance for loan losses: Beginning Balance $ 239 $ 358 $ 1,875 $ 619 $ 282 $ 80 $ 3,453 Charge-offs (20 ) — (117 ) (142 ) (23 ) (175 ) (477 ) Recoveries — 34 44 69 9 38 194 Provision 27 (7 ) 5 136 13 151 325 Ending Balance $ 246 $ 385 $ 1,807 $ 682 $ 281 $ 94 $ 3,495 Ending balance: individually evaluated for impairment $ — $ 29 $ 12 $ — $ — $ — $ 41 Ending balance: collectively evaluated for impairment $ 246 $ 356 $ 1,795 $ 682 $ 281 $ 94 $ 3,454 Loans outstanding: Ending Balance $ 33,449 $ 33,291 $ 235,689 $ 176,192 $ 37,491 $ 20,353 $ 536,465 Ending balance: individually evaluated for impairment $ — $ 4,552 $ 1,018 $ — $ — $ — $ 5,570 Ending balance: collectively evaluated for impairment $ 33,449 $ 28,739 $ 234,671 $ 176,192 $ 37,491 $ 20,353 $ 530,895 December 31, 2017 Allowance for loan losses: Beginning Balance $ 319 $ 342 $ 1,841 $ 600 $ 210 $ 108 $ 3,420 Charge-offs (33 ) (34 ) (89 ) (59 ) (27 ) (76 ) (318 ) Recoveries 56 — 23 — 33 22 134 Provision (103 ) 50 100 78 66 26 217 Ending Balance $ 239 $ 358 $ 1,875 $ 619 $ 282 $ 80 $ 3,453 Ending balance: individually evaluated for impairment $ — $ 49 $ 42 $ — $ — $ — $ 91 Ending balance: collectively evaluated for impairment $ 239 $ 309 $ 1,833 $ 619 $ 282 $ 80 $ 3,362 Loans outstanding: Ending Balance $ 25,475 $ 33,353 $ 199,120 $ 125,661 $ 25,672 $ 15,590 $ 424,871 Ending balance: individually evaluated for impairment $ — $ 5,069 $ 1,556 $ — $ — $ — $ 6,625 Ending balance: collectively evaluated for impairment $ 25,475 $ 28,284 $ 197,564 $ 125,661 $ 25,672 $ 15,590 $ 418,246 As of December 31, 2018 and December 31, 2017, 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 December 31, 2018 and December 31, 2017, respectively, the Bank had no loans graded “Doubtful” or “Loss” included in the balance of total loans outstanding.

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. The following table presents an age analysis of nonaccrual and past due loans by category as of December 31, 2018 and December 31, 2017: (dollars in thousands) 30-59 Days Past Due 60-89 Days Past Due 90 Days or More Past Due Total Past Due Current Total Loans 90+ Days Past Due and Still Accruing Nonaccrual Loans December 31, 2018 Real Estate Secured: Construction & development $ 29 $ — $ — $ 29 $ 33,420 $ 33,449 $ — $ — Farmland 71 100 989 1,160 32,131 33,291 — 3,914 Residential 762 145 241 1,148 234,541 235,689 — 653 Commercial mortgage — — 604 604 175,588 176,192 — 740 Non-Real Estate Secured: Commercial & agricultural 7 — 264 271 37,220 37,491 — 264 Consumer & other 12 18 8 38 20,315 20,353 — 8 Total $ 881 $ 263 $ 2,106 $ 3,250 $ 533,215 $ 536,465 $ — $ 5,579 December 31, 2017 Real Estate Secured: Construction & development $ — $ — $ 227 $ 227 $ 25,248 $ 25,475 $ — $ 226 Farmland 188 — 308 496 32,857 33,353 — 3,610 Residential 395 334 710 1,439 197,681 199,120 — 1,211 Commercial mortgage — — 194 194 125,467 125,661 — 194 Non-Real Estate Secured: Commercial & agricultural 70 — 23 93 25,579 25,672 — 94 Consumer & other 2 24 — 26 15,564 15,590 — — Total $ 655 $ 358 $ 1,462 $ 2,475 $ 422,396 $ 424,871 $ — $ 5,335 Impaired Loans A loan is considered impaired when it is probable that the Bank will be unable to collect all contractual principal and interest payments due in accordance with the original or modified terms of the loan agreement. Smaller balance homogenous loans may be collectively evaluated for impairment. Non-homogenous impaired loans are either measured based on the estimated fair value of the collateral less estimated cost to sell if the loan is considered collateral dependent, or measured based on the present value of expected future cash flows if not collateral dependent. The valuation of real estate collateral is subjective in nature and may be adjusted in future periods because of changes in economic conditions. Management considers third-party appraisals, as well as independent fair market value assessments in determining the estimated fair value of particular properties. In addition, as certain of these third-party appraisals and independent fair market value assessments are only updated periodically, changes in the values of specific properties may have occurred subsequent to the most recent appraisals. Accordingly, the amounts of any such potential changes and any related adjustments are generally recorded at the time such information is received. When the measurement of the impaired loan is less than the recorded investment in the loan, impairment is recognized by creating or adjusting an allocation of the allowance for loan losses and uncollected accrued interest is reversed against interest income. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance. As of December 31, 2018 and December 31, 2017, respectively, the recorded investment in impaired loans totaled $10.3 million and $12.3 million. The total amount of collateral-dependent impaired loans at December 31, 2018 and December 31, 2017, respectively, was $2.8 million and $3.7 million. As of December 31, 2018 and December 31, 2017, respectively, $3.4 million and $3.7 million of the recorded investment in impaired loans did not have a related allowance. The Bank had $7.3 million and $8.6 million in troubled debt restructured loans included in impaired loans at December 31, 2018 and December 31, 2017, respectively. The categories of non-accrual loans and impaired loans overlap, although they are not coextensive. The Bank considers all circumstances regarding the loan and borrower on an individual basis when determining whether an impaired loan should be placed on non-accrual status, such as the financial strength of the borrower, the estimated collateral value, reasons for the delay, payment record, the amount past due and the number of days past due. In 2015, management began collectively evaluating performing TDRs with a loan balance of $250,000 or less for impairment. As of December 31, 2018 and December 31, 2017, respectively, $4.7 million and $5.7 million of TDRs included in the following table were evaluated collectively for impairment and were deemed to have $259 thousand and $303 thousand of related allowance.

Investments, All Other Investments [Abstract]
Financial Instruments	Note 13. 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 December 31, 2018 and December 31, 2017. 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. For loans, the carrying amount is net of unearned income and the allowance for loan losses. In accordance with the prospective adoption of ASU No. 2016-01, the fair value of loans as of December 31, 2018 was measured using an exit price notion. The fair value of loans as of December 31, 2017 was measured using an entry price notion. Fair Value Measurements (dollars in thousands) Carrying Amount Fair Value Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2018 Financial Instruments – Assets Net Loans $ 532,970 $ 529,155 $ — $ 528,784 $ 371 Financial Instruments – Liabilities Time Deposits 180,143 176,188 — 176,188 — December 31, 2017 Financial Instruments – Assets Net Loans $ 421,418 $ 417,229 $ — $ 416,426 $ 803 Financial Instruments – Liabilities Time Deposits 147,725 144,656 — 144,656 — 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 markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include asset-backed securities in less liquid markets. 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, 2018, 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. Derivative Assets and Liabilities Derivative instruments held or issued by the Company for risk management purposes are traded in over-the-counter markets where quoted market prices are not readily available. Management engages third-party intermediaries to determine the fair market value of these derivative instruments and classifies these instruments as Level 2. Examples of Level 2 derivatives are interest rate swaps, caps and floors. No derivative instruments were held during the years ended December 31, 2018 or 2017. 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 December 31, 2018 or 2017. Assets measured at fair value on a nonrecurring basis are included in the table below.

Retirement Benefits [Abstract]
Employee Benefit Plans	Note 14. Employee Benefit Plans 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. A summary of each plan follows: Grayson Plan The following is a summary of the plan’s funded status as of December 31: (dollars in thousands) 2018 2017 Change in benefit obligation Benefit obligation at beginning of year $ 5,223 $ 4,783 Interest cost 173 191 Actuarial (gain) loss (824 ) 637 Benefits paid (79 ) (380 ) Settlement (gain) loss — (8 ) Benefit obligation at end of year 4,493 5,223 Change in plan assets Fair value of plan assets at beginning of year 8,513 7,894 Actual return on plan assets (342 ) 999 Benefits paid (79 ) (380 ) Fair value of plan assets at end of year 8,092 8,513 Funded status at the end of the year $ 3,599 $ 3,290 (dollars in thousands) 2018 2017 Amounts recognized in the Balance Sheet Plan benefit cost $ 4,912 $ 4,539 Unrecognized net actuarial loss (1,313 ) (1,249 ) Amount recognized in other assets $ 3,599 $ 3,290 Amounts recognized in accumulated comprehensive income (loss) Unrecognized net actuarial loss $ (1,313 ) $ (1,249 ) Deferred taxes 275 262 Amount recognized in accumulated comprehensive income (loss), net $ (1,038 ) $ (987 ) Prepaid benefit detail Benefit obligation $ (4,493 ) $ (5,223 ) Fair value of assets 8,092 8,513 Unrecognized net actuarial loss 1,313 1,249 Prepaid benefit cost 4,912 4,539 Components of net periodic pension cost Interest cost $ 173 $ 191 Expected return on plan assets (576 ) (552 ) Recognized net loss due to settlement — 86 Recognized net actuarial loss 30 28 Net periodic benefit expense (373 ) (247 ) Additional disclosure information Accumulated benefit obligation $ 4,493 $ 5,223 Vested benefit obligation $ 4,493 $ 5,223 Discount rate used for net periodic pension cost 3.50 % 4.00 % Discount rate used for disclosure 4.25 % 3.50 % Expected return on plan assets 7.00 % 7.00 % Rate of compensation increase N/A N/A Average remaining service (years) 12 13 Using the same fair value hierarchy described in Note 13, the fair values of the Company’s pension plan assets, by asset category, are as follows: (dollars in thousands) Total Level 1 Level 2 Level 3 December 31, 2018 Cash equivalents and short term investments $ — $ — $ — $ — Mutual funds – equities 3,848 3,848 — — Mutual funds – fixed income 4,244 4,244 — — Total assets at fair value $ 8,092 $ 8,092 $ — $ — December 31, 2017 Cash equivalents and short term investments $ — $ — $ — $ — Mutual funds – equities 4,368 4,368 — — Mutual funds – fixed income 4,145 4,145 — — Total assets at fair value $ 8,513 $ 8,513 $ — $ — Estimated Future Benefit Payments (dollars in thousands) Pension Benefits 2019 $ 439 2020 15 2021 250 2022 210 2023 1,091 2024 – 2028 1,407 $ 3,412 Funding Policy It has been Bank practice to contribute the maximum tax-deductible amount each year as determined by the plan administrator. As a result of prior year contributions exceeding the minimum requirements, a Prefunding Balance existed as of December 31, 2018 and there is no required contribution for 2019. Based on this we do not anticipate making a contribution to the plan in 2019. Long-Term Rate of Return The plan sponsor selects the expected long-term rate-of-return-on-assets assumption in consultation with their investment advisors and actuary. This rate is intended to reflect the average rate of earnings expected to be earned on the funds invested or to be invested to provide plan benefits. Historical performance is reviewed – especially with respect to real rates of return (net of inflation) – for the major asset classes held, or anticipated to be held by the trust, and for the trust itself. Undue weight is not given to recent experience – that may not continue over the measurement period – with higher significance placed on current forecasts of future long-term economic conditions. Because assets are held in a qualified trust, anticipated returns are not reduced for taxes. Further – solely for this purpose the plan is assumed to continue in force and not terminate during the period during which the assets are invested. However, consideration is given to the potential impact of current and future investment policy, cash flow into and out of the trust, and expenses (both investment and non-investment) typically paid from plan assets (to the extent such expenses are not explicitly estimated within periodic cost). Asset Allocation The pension plan’s weighted-average asset allocations at December 31, 2018 and 2017, by asset category are as follows: 2018 2017 Mutual funds – fixed income 52 % 49 % Mutual funds – equity 48 % 51 % Cash and equivalents 0 % 0 % Total 100 % 100 % The trust fund is sufficiently diversified to maintain a reasonable level of risk without imprudently sacrificing return, with a targeted asset allocation of 50 percent fixed income and 50 percent equities. The Investment Manager selects investment fund managers with demonstrated experience and expertise, and funds with demonstrated historical performance, for the implementation of the Plan’s investment strategy. The Investment Manager will consider both actively and passively managed investment strategies and will allocate funds across the asset classes to develop an efficient investment structure. It is the responsibility of the Trustee to administer the investments of the Trust within reasonable costs, being careful to avoid sacrificing quality. These costs include, but are not limited to, management and custodial fees, consulting fees, transaction costs and other administrative costs chargeable to the Trust. Floyd Plan The Company participates in the Pentegra Defined Benefit Plan for Financial Institutions (“The Pentegra DB Plan”), a tax-qualified defined-benefit pension plan. The Pentegra DB Plan operates as 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. There are no collective bargaining agreements in place that require contributions to the Pentegra DB Plan. The Pentegra DB Plan is a single plan under Internal Revenue Code Section 413 (C) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra DB Plan, contributions made by a participating employer may be used to provide benefits to participants of other participating employers. Funded Status (market value of plan assets divided by funding target) as of July 1 , 2018 Valuation 2017 Valuation Source Report Report Bank of Floyd Plan 106.44 % 108.63 % Employer Contributions Plan expenses paid by the Company totaled approximately $54 thousand and $58 thousand for the years ended December 31, 2018 and 2017, respectively.

Deferred Compensation and Supplemental Executive Retirement Plans	Note 15. Deferred Compensation and Supplemental Executive Retirement Plans Deferred compensation plans have been adopted for certain executive officers and members of the Board of Directors for future compensation upon retirement. Under plan provisions aggregate annual payments ranging from $1,992 to $37,200 are payable for ten Supplemental executive retirement plans for certain executive officers were adopted in 2017. The plans provide for annual payments ranging from $55,000 to $90,000, payable in monthly installments, and continuing for the life of the executive. Reduced benefits apply in cases of early retirement. The liability accrued for this obligation was $143 thousand and $36 thousand at December 31, 2018 and 2017, respectively. Expense charged against income and included in salary and benefits expense was $107 thousand and $36 thousand in 2018 and 2017 respectively for these supplemental executive retirement plans. Prior to the Cardinal merger, the Bank of Floyd had adopted supplemental executive plans to provide benefits for two subsequent to the executive’s last day of employment.

Under ASC 740, the effects of changes in tax rates and laws are recognized in the period in which the new legislation is enacted. As a result, the Company’s income tax expense for the year ended December 31, 2017 includes tax expense from the re-measurement of deferred assets and liabilities totaling $1.4 million. The Bank has analyzed the tax positions taken or expected to be taken in its tax returns and concluded it has no liability related to uncertain tax positions in accordance with applicable regulations. Tax returns for the years subsequent to 2015 remain subject to examination by both federal and state tax authorities. Deferred tax assets or liabilities are initially recognized for differences between the financial statement carrying amount and the tax basis of assets and liabilities which will result in future deductible or taxable amounts and operating loss and tax credit carry-forwards. A valuation allowance is then established, as applicable, to reduce the deferred tax asset to the level at which it is “more likely than not” that the tax benefits will be realized. Sources of taxable income that may allow for the realization of tax benefits include (1) taxable income in the current year or prior years that is available through carry-back, (2) future taxable income that will result from the reversal of existing taxable temporary differences, and (3) taxable income generated by future operations. There is no valuation allowance for deferred tax assets as of December 31, 2018 and 2017. The net operating loss of approximately $8.3 million, if not utilized, will begin to expire in 2031. It is management’s belief that realization of the deferred tax asset is more likely than not.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 17. 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 Sheet Risk The Bank is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, credit risk in excess of the amount recognized in the consolidated balance sheets. 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 sheet instruments. A summary of the Bank’s commitments at December 31, 2018 and 2017 is as follows: (dollars in thousands) 2018 2017 Commitments to extend credit $ 76,977 $ 56,912 Standby letters of credit 1,227 1,106 $ 78,204 $ 58,018 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 basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, inventory, property and equipment, residential real estate and income-producing commercial properties. 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.

Related Party Transactions [Abstract]
Transactions with Related Parties	Note 18. Transactions with Related Parties The Bank has entered into transactions with its directors, significant stockholders and their affiliates (related parties). Such transactions were made in the ordinary course of business on substantially the same terms and conditions, including interest rates and collateral, as those prevailing at the same time for comparable transactions with other customers, and did not, in the opinion of management, involve more than normal credit risk or present other unfavorable features. Aggregate 2018 and 2017 loan transactions with related parties were as follows: (dollars in thousands) 2018 2017 Balance, beginning $ 4,769 $ 5,112 New loans 2,662 1,388 Repayments (2,502 ) (1,228 ) Change in relationship 2,620 (503 ) Balance, ending $ 7,549 $ 4,769 The Company has accepted deposits during the ordinary course of business from certain directors and executive officers of the Company and from their affiliates and associates. The total amount of these deposits outstanding was $8.2 million, and $10.7 million at December 31, 2018 and 2017, respectively.

Regulatory Restrictions

Regulatory Restrictions	12 Months Ended
	Dec. 31, 2018
Banking and Thrift [Abstract]
Regulatory Restrictions	Note 19. Regulatory Restrictions Dividends The Company’s dividend payments are generally made from dividends received from the Bank. Under applicable federal law, the Comptroller of the Currency restricts national bank total dividend payments in any calendar year to net profits of that year, as defined, combined with retained net profits for the two preceding years. The Comptroller also has authority under the Financial Institutions Supervisory Act to prohibit a national bank from engaging in an unsafe or unsound practice in conducting its business. It is possible, under certain circumstances, the Comptroller could assert that dividends or other payments would be an unsafe or unsound practice. Intercompany Transactions The Bank’s legal lending limit on loans to the Company is governed by Federal Reserve Act 23A, and differs from legal lending limits on loans to external customers. Generally, a bank may lend up to 10 percent of its capital and surplus to its Parent, if the loan is secured. If collateral is in the form of stocks, bonds, debentures or similar obligations, it must have a market value when the loan is made of at least 20 percent more than the amount of the loan, and if obligations of a state or political subdivision or agency thereof, it must have a market value of at least 10 percent more than the amount of the loan. If such loans are secured by obligations of the United States or agencies thereof, or by notes, drafts, bills of exchange or bankers’ acceptances eligible for rediscount or purchase by a Federal Reserve Bank, requirements for collateral in excess of the loan amount do not apply. Under this definition, the legal lending limit for the Bank on loans to the Company was approximately $7.6 million at December 31, 2018. No 23A transactions were deemed to exist between the Company and the Bank at December 31, 2018. Capital Requirements The Bank is subject to various regulatory capital requirements administered by federal and state 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 the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Effective January 1, 2015, the federal banking regulators adopted rules to implement the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision and certain provisions of the Dodd-Frank Act. The final rules required the Bank to comply with the following minimum capital ratios: (i) a common equity Tier 1 capital ratio of 4.5% of risk-weighted assets; (ii) a Tier 1 capital ratio of 6% of risk-weighted assets; (iii) a total capital ratio of 8% of risk-weighted assets; and (iv) a leverage ratio of 4% of total assets. As fully phased in on January 1, 2019 The capital conservation buffer requirement has been phased in beginning January 1, 2016, at 0.625% of risk-weighted assets, increasing by the same amount each year until fully implemented at 2.5% on January 1, 2019. The capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of common equity Tier 1 to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall. The rules also revised the prompt corrective action framework, which is designed to place restrictions on insured depository institutions if their capital levels begin to show signs of weakness. Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions are required to meet the following capital level requirements in order to qualify as “well capitalized:” a common equity Tier 1 capital ratio of 6.5% 8% 10%; and a Tier 1 leverage ratio of 5%. The Bank’s actual capital amounts and ratios are presented in the following table as of December 31, 2018 and 2017. These ratios comply with Federal Reserve rules to align with the Basel III Capital requirements effective January 1, 2015. Actual For Capital Adequacy Purposes To Be Well- Capitalized Amount Ratio Amount Ratio Amount Ratio December 31, 2018 Total Capital (to risk weighted assets) $ 71,424 13.00 % $ 43,943 8.00 % $ 54,929 10.00 % Tier 1 Capital (to risk weighted assets) $ 67,899 12.36 % $ 32,958 6.00 % $ 43,943 8.00 % Common Equity Tier 1 (to risk weighted assets) $ 67,899 12.36 % $ 24,718 4.50 % $ 35,704 6.50 % Tier 1 Capital (to average total assets) $ 67,899 10.08 % $ 26,932 4.00 % $ 33,664 5.00 % December 31, 2017 Total Capital (to risk weighted assets) $ 56,962 13.14 % $ 34,688 8.00 % $ 43,360 10.00 % Tier 1 Capital (to risk weighted assets) $ 53,483 12.33 % $ 26,016 6.00 % $ 34,688 8.00 % Common Equity Tier 1 (to risk weighted assets) $ 53,483 12.33 % $ 19,512 4.50 % $ 28,184 6.50 % Tier 1 Capital (to average total assets) $ 53,483 9.81 % $ 21,808 4.00 % $ 27,260 5.00 % As directed by the Economic Growth Act, on November 21, 2018 , the federal banking regulators jointly issued a proposed rule that would permit qualifying banks that have less than $ 10 billion in total consolidated assets to elect to be subject to a 9 % “community bank leverage ratio.” A qualifying bank that has chosen the proposed framework would not be required to calculate the existing risk-based and leverage capital requirements and would be considered to have met the capital ratio requirements to be “well capitalized” under prompt corrective action rules, provided it has a community bank leverage ratio greater than 9 %. This proposed rule has not been finalized and, as a result, the content and scope of any final rule, and its impact on the Bank (if any), cannot be determined at this time.

Subsequent Events [Abstract]
Subsequent Events	Note 21. Subsequent Events Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Non-recognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Management has reviewed the events occurring through the date the consolidated financial statements were issued and, other than what is disclosed below, no subsequent events occurred requiring accrual or disclos ure. In January 2019, the Board of Directors of the Company approved a stock repurchase plan. The Board of Directors has authorized an initial repurchase of up to 200,000 shares of its common stock from time to time for a period of two years ending in January 2021. The Company intends to purchase shares periodically through privately negotiated transactions or in the open market in accordance with Securities and Exchange Commission rules. The actual timing, number and value of shares repurchased under the plan will be determined by management in its discretion and will depend on a number of factors, including the market price of the shares, general market and economic conditions, applicable legal requirements and other conditions.

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2018
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. A business combination occurs when the Company acquires net assets that constitute a business, or acquires equity interests in one or more other entities that are businesses and obtains control over those entities. Business combinations are effected through the transfer of consideration consisting of cash and/or common stock and are accounted for using the acquisition method. Accordingly, the assets and liabilities of the acquired entity are recorded at their respective fair values as of the closing date of the acquisition. Determining the fair value of assets and liabilities, especially the loan portfolio, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values. Fair values are subject to refinement for up to one year after the closing date of the acquisition as information relative to closing date fair values becomes available. The results of operations of an acquired entity are included in our consolidated results from the closing date of the merger, and prior periods are not restated. No allowance for loan losses related to the acquired loans is recorded on the acquisition date because the fair value of the loans acquired incorporates assumptions regarding future credit losses. The fair value estimates associated with the acquired loans include estimates related to expected prepayments and the amount and timing of expected principal, interest and other cash flows.
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 collectability 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 are reported at their outstanding principal amount adjusted for any charge-offs and the allowance for loan losses. Loan origination costs are capitalized and recognized as an adjustment to yield over the life of the related loan. 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 with evidence of credit deterioration since origination, and for which it is probable that all contractually required payments will not be collected, are considered credit impaired. Evidence of credit quality deterioration as of the purchase date may include statistics such as internal risk grade and past due and nonaccrual status. Purchased impaired loans generally meet the Company’s definition for nonaccrual status. PCI loans are initially measured at fair value, which reflects estimated future credit losses expected to be incurred over the life of the loan. Accordingly, the associated allowance for credit losses related to these loans is not carried over at the acquisition date. Any excess of cash flows expected at acquisition over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference, and is available to absorb credit losses on those loans. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent significant increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges, or a reclassification of the nonaccretable difference with a positive impact on future interest income.
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 thereof, 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 collectability 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 loans, which are considered impaired. A specific allowance is established when the discounted cash flows, collateral value (less disposal costs), or observable market price of the impaired loan is lower than its carrying value. The specific component of the allowance for smaller-balance loans whose terms have been modified in a troubled debt restructuring (TDR) is calculated on a pooled basis considering historical experience adjusted for qualitative factors. The general component covers non-impaired loans and is based on historical loss experience adjusted for qualitative factors. An unallocated component is maintained to cover uncertainties that could affect management’s estimate of probable losses. The unallocated component of the allowance reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for estimating specific and general losses in the portfolio. 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 basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan by loan basis for all loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. 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 loans.
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 Cardinal 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 Cardinal 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.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill arises from business combinations and is generally determined as the excess of fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquire, over the fair value of the nets assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently in events and circumstances exists that indicate that a goodwill impairment test should be performed. The Company has selected July 1, 2019 as the date to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. Other intangible assets consist of core deposit intangibles that 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
Revenue Recognition	Revenue Recognition On January 1, 2018, we adopted the requirements of Accounting Standards Update (“ASU”) 2014-9, Revenue from Contracts with Customers (“ASU Topic 606”) . The Company completed its overall assessment of revenue streams and review of related contracts potentially affected by the ASU, including deposit related fees, interchange fees, merchant income, and annuity and insurance commissions. Based on this assessment, the Company concluded that ASU 2014-09 did not materially change the method in which the Company currently recognizes revenue for these revenue streams. The Company also completed its evaluation of certain costs related to these revenue streams to determine whether such costs should be presented as expenses or contra-revenue (i.e., gross vs. net). Based on its evaluation, the Company determined that ASU 2014-09 did not materially change the method in which the Company currently classifies certain costs associated with the related revenue streams. The Company adopted ASU 2014-09 and its related amendments on its required effective date of January 1, 2018 utilizing the modified retrospective approach. Since there was no net income impact upon adoption of the new guidance, a cumulative effect adjustment to opening retained earnings was not deemed necessary.
Income Taxes	Income Taxes Provision for income taxes is based on amounts reported in the statements of income (after exclusion of non-taxable income such as interest on state and municipal securities) and consists of taxes currently due plus deferred taxes on temporary differences in the recognition of income and expense for tax and financial statement purposes. Deferred tax assets and liabilities are included in the financial statements at currently enacted income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. 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. The Company has early adopted ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” which is considered a change in accounting principle. Because the required adjustment of deferred taxes is required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (commonly referred to as “stranded” tax effects) would not reflect the appropriate tax rate. Adoption of this ASU eliminates the “stranded” tax effects associated with the change in the federal corporate income tax rate in the Tax Cuts and Jobs Act of 2017. The Company has reclassified “stranded” tax effects totaling $248 thousand from accumulated other comprehensive loss to retained earnings and these reclassified amounts are reflected in the accompanying consolidated statements of changes in stockholders’ equity.
Comprehensive Income	Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) 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: (dollars in thousands) Unrealized Gains And Losses On Available for Sale Securities Defined Benefit Pension Items Total Balance, December 31, 2016 $ (574 ) $ (780 ) $ (1,354 ) Other comprehensive income (loss) before reclassifications 296 (44 ) 252 Amounts reclassified from accumulated other comprehensive loss (160 ) — (160 ) Amounts reclassified to retained earnings from other comprehensive loss due to tax rate change (85 ) (163 ) (248 ) Balance, December 31, 2017 $ (523 ) $ (987 ) $ (1,510 ) Balance, December 31, 2017 $ (523 ) $ (987 ) $ (1,510 ) Other comprehensive income (loss) before reclassifications (402 ) (51 ) (453 ) Amounts reclassified from accumulated other comprehensive loss (4 ) — (4 ) Balance, December 31, 2018 $ (929 ) $ (1,038 ) $ (1,967 )
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.
Off-Balance Sheet Credit Related Financial Instruments	Off-Balance Sheet Credit Related Financial Instruments 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 13. 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 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. We expect to adopt the guidance using the modified retrospective method and practical expedients for transition. The practical expedients allow us to largely account for our existing leases consistent with current guidance except for the incremental balance sheet recognition for lessees. We have performed an evaluation of our leasing contracts and activities. We have developed our methodology to estimate the right-of use assets and lease liabilities, which is based on the present value of lease payments. At December 31, 2018 future minimum lease payments were approximately $334 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. Early adoption is permitted for all organizations for periods beginning after December 15, 2018. The Company will apply the amendments to the ASU through a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption. While early adoption is permitted beginning in first quarter 2019, we do not expect to elect that option. We are evaluating the impact of the ASU on our consolidated financial statements. We expect the ASU will result in an increase in the recorded allowance for loan losses given the change to estimated losses over the contractual life of the loans adjusted for expected prepayments. The majority of the increase results from longer duration portfolios. In addition to our allowance for loan losses, we will also record an allowance for credit losses on debt securities instead of applying the impairment model currently utilized. The amount of the adjustments will be impacted by each portfolio’s composition and credit quality at the adoption date as well as economic conditions and forecasts at that time. 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 . Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 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 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. In February 2018, the FASB amended the Financial Instruments Topic of the Accounting Standards Codification. The amendments clarify certain aspects of the guidance issued in ASU 2016-01. The amendments are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years beginning after June 15, 2018. All entities may early adopt these amendments for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, as long as they have adopted ASU 2016-01. The Company does not expect these amendments to have a material effect on its financial statements. In March 2018, the FASB updated the Debt Securities and the Regulated Operations Topics of the Accounting Standards Codification. The amendments incorporate into the Accounting Standards Codification recent SEC guidance which was issued in order to make the relevant interpretive guidance consistent with current authoritative accounting and auditing guidance and SEC rules and regulations. The amendments were effective upon issuance. The Company does not expect these amendments to have a material effect on its financial statements. In March 2018, the FASB updated the Income Taxes Topic of the Accounting Standards Codification. The amendments incorporate into the Accounting Standards Codification recent SEC guidance related to the income tax accounting implications of the Tax Cuts and Jobs Act. The amendments were effective upon issuance. The Company does not expect these amendments to have a material effect on its financial statements. In May 2018, the FASB amended the Financial Services—Depository and Lending Topic of the Accounting Standards Codification to remove outdated guidance related to Circular 202. The amendments were effective upon issuance and did not have a material effect on the financial statements. In July 2018, the FASB amended the Leases Topic of the Accounting Standards Codification to make narrow amendments to clarify how to apply certain aspects of the new leases standard. The amendments are effective for reporting periods beginning after December 15, 2018. The Company does not expect these amendments to have a material effect on its financial statements. In July 2018, the FASB amended the Leases Topic of the Accounting Standards Codification to give entities another option for transition and to provide lessors with a practical expedient. The amendments will be effective for the Company for reporting periods beginning after December 15, 2018. The Company does not expect these amendments to have a material effect on its financial statements. In August 2018, the FASB amended the Fair Value Measurement Topic of the Accounting Standards Codification. The amendments remove, modify, and add certain fair value disclosure requirements based on the concepts in the FASB Concepts Statement, Conceptual Framework for Financial Reporting—Chapter 8: Notes to Financial Statements . The amendments are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company does not expect these amendments to have a material effect on its financial statements. In August 2018, the FASB amended the Intangibles—Goodwill and Other Topic of the Accounting Standards Codification to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The amendments will be effective for the Company for fiscal years beginning after December 15, 2019. Early adoption is permitted. The Company does not expect these amendments to have a material effect on its financial statements. In October 2018, the FASB amended the Derivatives and Hedging Topic of the Accounting Standards Codification to expand the list of U.S. benchmark interest rates permitted in the application of hedge accounting. The amendments will be effective for the Company for fiscal years 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. In November 2018, the FASB amended the Collaborative Arrangements Topic of the Accounting Standards Codification to clarify the interaction between the guidance for certain collaborative arrangements and the new revenue recognition financial accounting and reporting standard. The amendments will be effective for the Company for fiscal years beginning after December 15, 2019, and 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 2018, the FASB issued guidance that providing narrow-scope improvements for lessors, that provides relief in the accounting for sales, use and similar taxes, the accounting for other costs paid by a lessee that may benefit a lessor, and variable payments when contracts have lease and non-lease components. The amendments will be effective for the Company for reporting 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.
