(“Virginia BanCorp”), a bank holding company conducting substantially all of its operations through its subsidiary, Virginia Commonwealth Bank, completed a merger pursuant to the Agreement and Plan of Merger, dated as of November 2, 2016, by and between the Company and Virginia BanCorp (the “Merger”). The Company is the surviving corporation in the Merger, and the former shareholders of Virginia BanCorp received 1.178 shares of the Company’s common stock for each share of Virginia BanCorp common stock they owned immediately prior to the merger, for a total issuance of 4,586,221 shares of the Company’s common stock valued at approximately $42.2 million at the time of closing. As of the completion of the Merger, the Company’s legacy shareholders owned approximately 51% of the outstanding common stock of the Company, and Virginia BanCorp’s former shareholders owned approximately 49% of the outstanding common stock of the Company. After the Merger of Virginia BanCorp with and into the Company, Virginia BanCorp’s subsidiary bank was merged with and into Bank of Lancaster, a wholly owned subsidiary of the Company, and immediately thereafter Bank of Lancaster changed its name to Virginia Commonwealth Bank. The Merger was accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations The following table details the total consideration paid by the Company, in connection with the acquisition of Virginia BanCorp, the fair value of the assets acquired and liabilities assumed, and the resulting goodwill.

The Company also had an investment in Federal Reserve Bank of Richmond (“FRB”) stock, which totaled $2.3 million at September 30, 2018 and $1.9 million at December 31, 2017. The investments in both FHLB and FRB stock are required investments related to the Bank’s membership in the FHLB and FRB. These securities do not have a readily determinable fair value as their ownership is restricted, and they lack an active market for trading. Additionally, per charter provisions related to the FHLB and FRB stock, all repurchase transactions of such stock must occur at par. Accordingly, these securities are carried at cost and are periodically evaluated for impairment.

Loans	Note 5: Loans Loans are reported at their recorded investment, which is the outstanding principal balance net of any unearned income, such as deferred fees and costs, charge-offs, and acquisition accounting adjustments (discounts) on acquired loans. Interest on loans is recognized over the term of the loan and is calculated using the interest method on principal amounts outstanding. Loan origination fees and certain direct origination costs are deferred and recognized as an adjustment of the related loan yield over the contractual term of the loan, adjusted for early pay-offs, where applicable. All interest accrued but not collected for loans that are placed on nonaccrual or charged off are reversed against interest income at the time the loan is classified as nonaccrual. Any subsequent interest received on these loans is recognized as interest income on the cash basis until the loan qualifies to return to accrual status. Generally, a loan is returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured, or it becomes well-secured and in the process of collection. The following is a summary of the balances of loans as of the dates stated.

Allowance for Loan Losses

Allowance for Loan Losses	Note 6: Allowance for Loan Losses The allowance for loan losses (“ALL”) reflects management’s judgment of probable loan losses inherent in the loan portfolio at the balance sheet date. Management uses a disciplined process and methodology to establish the ALL each quarter. To determine the total ALL, the Company estimates the reserves needed for each homogenous segment and class of the loan portfolio, and for any loans analyzed individually for impairment. Depending on the nature of each segment and class, considerations include historical loss experience, adverse situations that may affect a borrower’s ability to repay, credit scores, past due history, estimated value of any underlying collateral, prevailing local and national economic conditions, and internal policies and procedures, including credit risk management and underwriting. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as conditions change. The ALL consists of specific, general, and unallocated components. The specific component is determined by identifying impaired loans (as described below) then evaluating those meeting certain criteria to calculate the amount of impairment. Impaired loans measured for impairment generally include (1) any loan risk rated Special Mention or worse where the borrower has filed for bankruptcy; and (2) all loans risk rated Substandard or worse with balances of $400 thousand or more; and (3) all loans classified as a troubled debt restructuring (“TDR”). A specific allowance is held when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component of the ALL is the result of the collective evaluation of any loans not identified as impaired or evaluated as impaired and are grouped into segments and classes. Historical loss experience is calculated and applied to each segment or class, as well as adjustments for qualitative factors. Qualitative factors include changes in local and national economic indicators, such as unemployment rates, interest rates, gross domestic product growth, and real estate market trends; the level of past due and nonaccrual loans; risk ratings on individual loans; strength of credit policies and procedures; loan officer experience; borrower credit scores; and other intrinsic risks related to the types and geographic locations of loans. These qualitative adjustments reflect management’s judgment of risks inherent in the segments. An unallocated component is maintained, if needed, to cover uncertainties that could affect management’s estimate of probable losses. Changes in the allowance for loan losses and the related provision expense can materially affect net income. Loans Evaluated for Impairment The following table shows loans evaluated for impairment individually and collectively by segment as of the dates stated.

For non-homogenous loans, management reviews these resulting grade assignments and makes adjustments to the final grade where appropriate based on an assessment of additional external information that may affect a particular loan. For purchased consumer loans, a loan is rated “substandard” when it is 90 days or more past due; otherwise, the loan is graded “pass”. Risk rating categories are as follows: Pass Watch Special Mention Substandard Doubtful Loss The following tables show the risk rating of loans as of the dates stated.

In cases where borrowers are granted new terms that provide for a reduction of either interest or principal or an extension of the maturity date at a stated interest rate lower than the current market rate for new debt with similar risks, the related loan is classified as a troubled debt restructuring. Management strives to identify borrowers in financial difficulty early and may work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance, and other actions intended to minimize the economic loss to the Company. Loans modified as TDRs are considered impaired and are individually evaluated for impairment for the ALL.

Earnings Per Share [Abstract]
Earnings per share	Note 8: Earnings per share The following table shows the weighted average number of shares used in computing earnings per share and the effect on the weighted average number of shares of dilutive potential common stock. Basic earnings per share amounts are computed by dividing the net income (the numerator) by the weighted average number of common shares outstanding (the denominator). Diluted earnings per share amounts assume the conversion, exercise, or issuance of all potential common stock instruments, unless the effect is to reduce the loss or increase the earnings per common share. For both computations, the weighted average number of employee stock ownership plan (“ESOP”) shares not committed to be released to participant accounts purchased by the ESOP are not assumed to be outstanding.

Borrowings	Note 10: Borrowings FHLB Borrowings As of September 30, 2018 and December 31, 2017, the Bank had $80.0 million and $70.0 million, respectively, of outstanding FHLB borrowings, consisting of three and two advances, respectively. Advances on the FHLB lines are secured by a blanket lien on qualified one-to-four family real estate, commercial real estate, and multifamily residential loans. Immediate available credit, as of September 30, 2018, was $150.1 million against a total line of credit of $245.1 million. Further information regarding the three advances outstanding as of September 30, 2018 are shown in the following table.

The notes have a maturity date of May 28, 2025 and bear interest, payable on the first of March and September of each year, at a fixed interest rate of 6.50% per year. The notes are not convertible into common stock or preferred stock and are not callable by the holders. The Company has the right to redeem the notes, in whole or in part, without premium or penalty, at any interest payment date on or after May 28, 2020, but in all cases in a principal amount with integral multiples of $1,000, plus interest accrued and unpaid through the date of redemption. If an event of default occurs, such as the bankruptcy of the Company, the holder of a note may declare the principal amount of the notes to be due and immediately payable. The notes are unsecured, subordinated obligations of the Company and rank junior in right of payment to the Company’s existing and future senior indebtedness. The notes qualify as Tier 2 capital for regulatory reporting. The aggregate carrying value of the notes, including capitalized debt issuance costs, was $6.9 million at both September 30, 2018 and December 31, 2017. For the three and nine months ended September 30, 2018 and 2017, the effective interest rate on the notes was 6.85% and 6.87%, respectively. ESOP Debt The aggregate carrying value of debt secured by shares of Company stock, issued and outstanding, in the Company’s ESOP was $1.0 million at September 30, 2018 and $1.1 million at December 31, 2017 and was included in other liabilities on the consolidated balance sheets. The debt is comprised of five fixed rate-amortizing notes, four of which carry an interest rate of 3.25% and one that carries an interest rate of 4.50% with maturity dates ranging from March 1, 2019 to December 31, 2027. Shares that collateralize these loans are not allocated to ESOP participants’ accounts.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 11: Fair Value Measurements The Company uses fair value to record certain assets and liabilities and to determine fair value disclosures. Authoritative accounting guidance clarifies that fair value of certain assets and liabilities is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value also assumes that the reporting entity would sell the asset or transfer the liability in the principal or most advantageous market. Authoritative accounting guidance specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The three levels of the fair value hierarchy based on these two types of inputs are as follows: Level 1 – Valuation is based on quoted prices in active markets for identical assets and liabilities. Level 2 – Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the market. Level 3 – Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market. The following describes the valuation techniques used by the Company to measure certain financial assets and liabilities recorded at fair value on a recurring basis in the financial statements: Available-for-sale securities Mortgage servicing rights (“MSR”) A third-party model is used to determine fair value, which establishes pools of performing loans, calculates cash flows for each pool, and applies a discount rate to each pool. Loans are segregated into 12 pools based on each loan’s term and seasoning (age). All loans have fixed interest rates. Cash flows are then estimated by utilizing assumed service costs and prepayment speeds. Monthly service costs were assumed to be $6.50 per loan as of September 30, 2018 and as of December 31, 2017. Prepayment speeds are determined primarily based on the average interest rate of the loans in each pool. The prepayment scale used is the Public Securities Association (“PSA”) model, where “100% PSA” means prepayments are zero in the first month, then increase by 0.2% of the loan balance each month until reaching 6.0% in month 30. Thereafter, the 100% PSA model assumes an annual prepayment of 6.0% of the remaining loan balance. The average PSA speed assumption in the fair value model is 128% and 150% as of September 30, 2018 and December 31, 2017, respectively. A discount rate of 12.5% and 13.0% was then applied to each pool as of September 30, 2018 and as of December 31, 2017, respectively. The discount rate is intended to represent the estimated market yield for the highest quality grade of comparable servicing. MSRs are classified as Level 3. The following table presents the balances of financial assets and liabilities measured at fair value on a recurring basis as of Fair Value Measurements as of September 30, 2018 Using Balance as of September 30, 2018 Level 1 Level 2 Level 3 Available-for-sale securities: U.

Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets. The following describes the valuation techniques used by the Company to measure certain assets recorded at fair value on a nonrecurring basis in the financial statements: Impaired Loans: Other Real Estate Owned: The following table summarizes the Company’s assets that were measured at fair value on a non-recurring basis as of the dates stated.

The carrying value of restricted securities approximates fair value based on the redemption provisions of the issuer. The fair value of performing loans is estimated by discounting the future cash flows using two sets of data sources. First, recent originations, occurring over the prior twelve months, were evaluated, and second, market data showing originations over the prior three months was evaluated. The selected rate was the greater of the two sources. For all loans other than a selective consumer loan portfolio, credit loss severity rates were calculated using the probability of default and the loss given default percentages derived from market data. For the consumer loan portfolio, historical delinquency data was obtained by the servicer of the portfolio. The fair value of impaired loans is measured as described within the Impaired Loans section of this note. The fair value of loans does consider the lack of liquidity and uncertainty in the market that might affect the valuation. Time deposits are presented at estimated fair value by discounting the future cash flows using recent issuance rates over the prior three months and a market rate analysis of recent offering rates. The fair value of the Company’s subordinated notes is estimated by utilizing recent issuance rates for subordinated debt offerings of similar issuer size. The fair value of the FHLB advances is estimated by discounting the future cash flows using current interest rates offered for similar advances. The fair value of commitments to extend credit is estimated using the fees currently charged to enter similar agreements, taking into account the remaining terms of the agreements and the present credit worthiness of the counter parties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of standby letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counter parties at the reporting date. At September 30, 2018 and December 31, 2017, the fair value of loan commitments and standby letters of credit was immaterial, and therefore not included in the table below. The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the fair value of the Company’s financial instruments will change when interest rate levels change and that change may be either favorable or unfavorable to the Company. Management attempts to match maturities of assets and liabilities to the extent believed necessary to minimize interest rate risk. However, borrowers with fixed rate obligations are less likely to prepay in a rising rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk. The following tables summarize the Company’s financial assets and liabilities at carrying values and estimated fair values on a nonrecurring basis as of the dates stated.

Accounting Policies [Abstract]
Basis of Presentation	The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (“GAAP”) and to the general practices within the banking industry. In management’s opinion, all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation of the consolidated financial statements, have been included. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year or for any other interim periods. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Certain amounts presented in the consolidated financial statements of prior periods have been reclassified to conform to current year presentations. The reclassifications had no effect on net income, net income per share, or shareholders’ equity as previously reported. All dollar amounts included in the tables in these notes are in thousands, except per share data, unless otherwise stated.
Loans	Loans are reported at their recorded investment, which is the outstanding principal balance net of any unearned income, such as deferred fees and costs, charge-offs, and acquisition accounting adjustments (discounts) on acquired loans. Interest on loans is recognized over the term of the loan and is calculated using the interest method on principal amounts outstanding. Loan origination fees and certain direct origination costs are deferred and recognized as an adjustment of the related loan yield over the contractual term of the loan, adjusted for early pay-offs, where applicable. All interest accrued but not collected for loans that are placed on nonaccrual or charged off are reversed against interest income at the time the loan is classified as nonaccrual. Any subsequent interest received on these loans is recognized as interest income on the cash basis until the loan qualifies to return to accrual status. Generally, a loan is returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured, or it becomes well-secured and in the process of collection.
Allowance for Loan Losses	The allowance for loan losses (“ALL”) reflects management’s judgment of probable loan losses inherent in the loan portfolio at the balance sheet date. Management uses a disciplined process and methodology to establish the ALL each quarter. To determine the total ALL, the Company estimates the reserves needed for each homogenous segment and class of the loan portfolio, and for any loans analyzed individually for impairment. Depending on the nature of each segment and class, considerations include historical loss experience, adverse situations that may affect a borrower’s ability to repay, credit scores, past due history, estimated value of any underlying collateral, prevailing local and national economic conditions, and internal policies and procedures, including credit risk management and underwriting. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as conditions change. The ALL consists of specific, general, and unallocated components. The specific component is determined by identifying impaired loans (as described below) then evaluating those meeting certain criteria to calculate the amount of impairment. Impaired loans measured for impairment generally include (1) any loan risk rated Special Mention or worse where the borrower has filed for bankruptcy; and (2) all loans risk rated Substandard or worse with balances of $400 thousand or more; and (3) all loans classified as a troubled debt restructuring (“TDR”). A specific allowance is held when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component of the ALL is the result of the collective evaluation of any loans not identified as impaired or evaluated as impaired and are grouped into segments and classes. Historical loss experience is calculated and applied to each segment or class, as well as adjustments for qualitative factors. Qualitative factors include changes in local and national economic indicators, such as unemployment rates, interest rates, gross domestic product growth, and real estate market trends; the level of past due and nonaccrual loans; risk ratings on individual loans; strength of credit policies and procedures; loan officer experience; borrower credit scores; and other intrinsic risks related to the types and geographic locations of loans. These qualitative adjustments reflect management’s judgment of risks inherent in the segments. An unallocated component is maintained, if needed, to cover uncertainties that could affect management’s estimate of probable losses. Changes in the allowance for loan losses and the related provision expense can materially affect net income.
Internal Risk Rating Grades	Internal Risk Rating Grades All loans in the Company’s loan portfolio, with the exception of purchased consumer loans, are risk rated using loan risk grading software that employs a variety of algorithms based on detailed account characteristics to include borrower’s payment history on a total relationship basis as well as loan to value exposure. For non-homogenous loans, management reviews these resulting grade assignments and makes adjustments to the final grade where appropriate based on an assessment of additional external information that may affect a particular loan. For purchased consumer loans, a loan is rated “substandard” when it is 90 days or more past due; otherwise, the loan is graded “pass”. Risk rating categories are as follows: Pass Watch Special Mention Substandard Doubtful Loss
Troubled Debt Restructuring	Troubled Debt Restructuring For economic or legal reasons related to a borrower’s financial condition, management may grant a concession to a borrower that it would not otherwise consider. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal or an extension of the maturity date at a stated interest rate lower than the current market rate for new debt with similar risks, the related loan is classified as a troubled debt restructuring. Management strives to identify borrowers in financial difficulty early and may work with them to modify their loan to more affordable terms before their loan reaches nonaccrual status. These modified terms may include rate reductions, principal forgiveness, payment forbearance, and other actions intended to minimize the economic loss to the Company.
