Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1 – Organization and Basis of Presentation Blue Ridge Bankshares, Inc. (the "Company"), a Virginia corporation, was formed in 1988 and is registered as a bank holding company under the Bank Holding Company Act of 1956, as amended. The Company is headquartered in Charlottesville, Virginia and conducts its business activities primarily through the branch offices of its wholly-owned subsidiary bank, Blue Ridge Bank, National Association (the "Bank") and its wealth and trust management subsidiary, BRB Financial Group, Inc. (the “Financial Group”). The Company exists primarily for the purposes of holding the stock of its subsidiaries, the Bank and the Financial Group. The Bank operates under a national charter and is subject to regulation by the Office of the Comptroller of the Currency (the “OCC”). Consequently, it undergoes periodic examinations by this regulatory authority. On January 31, 2021, the Company completed a merger with Bay Banks of Virginia, Inc. (“Bay Banks”), a bank holding company conducting substantially all its operations through its bank subsidiary, Virginia Commonwealth Bank, and the Financial Group (formerly VCB Financial Group, Inc.). Immediately following the Company’s merger with Bay Banks, Bay Banks’ subsidiary bank was merged with and into the Bank, while the Financial Group became a subsidiary of the Company (collectively, the “Bay Banks Merger”). The accompanying unaudited consolidated financial statements of the Company include the accounts of the Bank, the Financial Group, PVB Properties, LLC, and MoneyWise Payroll Solutions, Inc. (net of noncontrolling interest) and were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and to general practices within the banking industry. All significant intercompany balances and transactions have been eliminated in consolidation. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020 ("2020 Form 10-K"). Information contained herein as of September 30, 2021 includes the balances of Bay Banks; information contained herein as of and for the year ended December 31, 2020 does not include the balances of Bay Banks. Information for the nine months ended September 30, 2021 includes the operations of Bay Banks only for the period immediately following the effective date of the Bay Banks Merger (January 31, 2021) through September 30, 2021. In March 2021, the Company’s board of directors approved a three-for-two stock split (“Stock Split”) effected in the form of a 50 % stock dividend on the Company’s common stock outstanding paid on April 30, 2021 to shareholders of record as of April 20, 2021 . Cash was paid in lieu of fractional shares based on the closing price of common stock on the record date. References made to outstanding shares or per share amounts in the accompanying consolidated financial statements and disclosures have been adjusted to reflect the Stock Split for all periods presented, unless otherwise noted. On July 14, 2021, the Company and FVCBankcorp, Inc. (“FVCB”) jointly announced they had entered into a definitive agreement pursuant to which FVCB will merge with and into the Company in an all-stock merger of equals (the “FVCB Merger”). Pursuant to the agreement, shareholders of FVCB will receive 1.1492 shares of the Company’s common stock for each FVCB share held, with fractional shares paid in cash. The FVCB Merger is subject to customary closing conditions, including regulatory approvals and approval from the shareholders of both companies. The Company has learned that the Office of the Comptroller of the Currency (the “OCC”) identified certain regulatory concerns with Blue Ridge Bank that could impact the application process and timing of the FVCB Merger. Blue Ridge Bank has already commenced an initiative intended to fully address the OCC’s concerns. The Company anticipates the FVCB Merger will close in the second or third quarter of 2022. Certain amounts presented in the consolidated financial statements of prior periods have been reclassified to conform to current year presentations, including the following instances. The reclassifications had no effect on net income, net income per share, or shareholders’ equity as previously reported. Correction of Immaterial Classification Errors During the third quarter of 2021, the Company determined that its 35 % investment in a third-party insurance company, Hammond Insurance Agency, Inc. ("Hammond Insurance"), which had been reported on its consolidated balance sheets in goodwill and other intangible assets, should have been reported as other assets. Also during the third quarter of 2021, the Company determined that its acquisition of BluePoint Benefits, LLC ("BluePoint Benefits"), which had been reported on its consolidated balance sheets in other assets, should have been reported as goodwill. The Company has changed the classification of both investments on its December 31, 2020 consolidated balance sheets. The change in the classification for the investment in Hammond Insurance resulted in a $ 613 thousand and $ 341 thousand decrease from what was previously reported in the 2020 Form 10-K in goodwill and other intangible assets, respectively, with a corresponding increase of $ 954 thousand in other investments as of December 31, 2020. The change in the classification for the investment in BluePoint Benefits resulted in a $ 340 thousand decrease from what was previously reported in the 2020 Form 10-K in other assets with a corresponding increase of the same amount in goodwill as of December 31, 2020. Neither change in classification for the Company's investment in Hammond Insurance and BluePoint Benefits affected the Company's reported earnings for 2020 or total assets for 2020 on the Company's consolidated balance sheets. During the first quarter of 2021, the Company determined a loan arrangement with a third-party financial institution for the purpose of residential mortgage loan originations, which had been reported on its consolidated balance sheets in loans held for sale, should have been reported as loans held for investment. The Company has changed the classification of this loan on its December 31, 2020 consolidated balance sheet to reflect it as held for investment. The change in classification resulted in a $ 30.4 million decrease from what was previously reported in the Company’s 2020 Form 10-K in loans held for sale with a corresponding increase of the same amount in loans held for investment as of December 31, 2020. There were no outstanding loans under this arrangement as of September 30, 2021. The change in classification did not affect the Company’s reported earnings for 2020, the Company does not believe any material allowance for loan losses (“ALL”) would have been necessary for this loan as of December 31, 2020, and the Company believes its ALL was adequate as of December 31, 2020. This reclassification did not change total loans or total assets on the Company’s consolidated balance sheets. The Company evaluated the effect of the previously noted incorrect presentations, both qualitatively and quantitatively, and concluded that its previously issued financial statements were not materially misstated due to the changes in classification.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Amendments to the Accounting Standards Codification	Note 2 – Amendments to the Accounting Standards Codification In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. As a “smaller reporting company” under Securities and Exchange Commission (“SEC”) rules, the Company will be required to apply the guidance for fiscal years, and interim periods within those years, beginning after December 15, 2022. The Company has formed a cross-functional working group to assess and implement the requirements of ASU 2016-13 by the adoption date. In November 2019, the FASB issued ASU 2019-11, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This ASU addresses issues raised by stakeholders during the implementation of ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. Among other narrow-scope improvements, the new ASU clarifies guidance around how to report expected recoveries. “Expected recoveries” describes a situation in which an organization recognizes a full or partial write-off of the amortized cost basis of a financial asset, but then later determines that the amount written off, or a portion of that amount, will in fact be recovered. While applying the credit losses standard, stakeholders questioned whether expected recoveries were permitted on assets that had already shown credit deterioration at the time of purchase (also known as purchased credit-deteriorated (“PCD”) assets). In response to this question, the ASU permits organizations to record expected recoveries on PCD assets. In addition to other narrow technical improvements, the ASU also reinforces existing guidance that prohibits organizations from recording negative allowances for available-for-sale debt securities. The ASU includes effective dates and transition requirements that vary depending on whether or not an entity has already adopted ASU 2016-13. The Company is currently assessing the impact that ASU 2019-11 will have on its consolidated financial statements.

Business Combinations [Abstract]
Business Combinations	Note 3 – Business Combinations On January 31, 2021, the Company completed the Bay Banks Merger, which was accounted for as a business combination. At the effective date of the merger, Bay Banks’ shareholders received 0.5000 shares of the Company’s common stock in exchange for each share of Bay Banks common stock held (“Exchange Ratio”), plus cash in lieu of any fractional shares, resulting in the Company issuing 6,634,495 shares ( 9,951,743 shares on a post Stock Split basis) with an aggregate fair market value of $ 124.9 million based on the closing price of the Company’s common stock at January 29, 2021, the last trading day prior to the effective date of the merger, and paying $ 3.4 thousand in lieu of fractional shares. In addition, options to purchase 198,362 shares of Bay Banks common stock, whether vested or unvested, were converted to options to acquire 99,176 shares of the Company’s common stock ( 148,764 shares on a post Stock Split basis) at an estimated fair value of $ 472 thousand as of the merger date. Finally, Bay Banks had previously acquired $ 1.75 million of the Company’s subordinated notes, while the Bank had previously acquired $ 1.10 million of Bay Banks’ subordinated notes. In the merger, an effective settlement of the notes occurred in the amount of $ 650 thousand, which reduced the consideration paid. The Bay Banks Merger combined two banks with complementary capabilities and geographical focus, thus provided the opportunity for the organization to leverage its existing infrastructure, including people, processes and systems, across a larger asset base. The Company has accounted for the Bay Banks Merger under the acquisition method of accounting, whereby the acquired assets and assumed liabilities are recorded by the Company at their estimated fair values as of the effective date of the merger. Fair value estimates were based on management’s assessment of the best information available at the time of determination and are highly subjective. The following table presents the consideration paid in the merger and the summary balance sheet of Bay Banks as of the date of the merger inclusive of estimated fair value adjustments and the allocation of consideration paid in the merger to the acquired assets and assumed liabilities. Goodwill resulting from the Bay Banks Merger was $ 7.2 million. (Dollars in thousands, except per share data) Consideration paid: Reference: Company's common shares issued 9,951,743 A Purchase price per share $ 12.55 A, B Value of common stock issued $ 124,928 Estimated fair value of stock options 472 Cash in lieu of fractional shares 3 Total consideration paid $ 125,403 Effective settlement of subordinated notes ( 650 ) Total consideration paid less effective settlement of subordinated notes $ 124,753 Fair value of assets acquired: Cash and due from banks $ 44,066 Federal funds sold 1,732 Certificates of deposit 1,018 Securities available for sale 79,505 Restricted securities 4,385 Loans held for investment 1,030,433 C Loans held for sale 3,814 Premises and equipment 15,532 D Right-of-use asset 1,864 Other real estate owned 598 Bank owned life insurance 20,259 Mortgage servicing rights 987 Core deposit intangible 6,850 E Deferred tax asset, net 2,685 F Other assets 10,855 G Total assets $ 1,224,583 Fair value of liabilities assumed: Deposits $ 1,030,888 H FHLB borrowings 10,124 I FRB borrowings 24,815 Subordinated notes 31,850 J Other liabilities 9,359 Total liabilities $ 1,107,036 Net identifiable assets acquired at fair value $ 117,547 Goodwill $ 7,206 Reference: Explanation of reference: A Common shares issued and purchase price per share are presented on a post Stock Split basis . B The value of the shares of the Company's common stock exchanged for shares of Bay Banks common stock was based upon the closing price of the Company's common stock at January 29, 2021, the last trading day prior to the date of completion of the merger. C Reflective of a $ 17.9 million (or 1.70 %) fair value adjustment (discount) to the amortized cost of the loan portfolio acquired. D Reflective of a $ 4.4 million fair value adjustment (premium) over the net book value of premises and equipment acquired. E Core deposit intangible asset recorded to reflect the fair value of nonmaturity deposits, except for time deposits over $ 100,000 , assumed by the Company. F Reflective of a $ 2.1 million net deferred tax asset recorded on all fair value adjustments, excluding goodwill, at the statutory federal income tax rate of 21 %. G Reflective of a $ 203 thousand fair vale adjustment (premium) on other assets acquired. H Reflective of a $ 5.8 million fair value adjustment (premium) over the book value of time deposits assumed. I Reflective of a $ 124 thousand fair value adjustment (premium) on the $ 10 million Federal Home Loan Bank of Atlanta ("FHLB") advance assumed. J Reflective of a $ 950 thousand fair value adjustment (premium) over the book value of subordinated notes assumed. Cash and cash equivalents. The carrying amounts of cash, due from banks, federal funds sold, and certificates of deposit was deemed to be a reasonable estimate of fair value. Securities available for sale. The estimated fair value of investment securities acquired was based on quoted market and third-party broker provided prices as of the merger date. Restricted securities. The carrying amount of restricted equity securities was used as a reasonable estimate of fair value. These investments are carried at cost as no active trading market exists. Loans. The acquired loan portfolio was segregated into two categories for valuation purposes: purchased credit-impaired (“PCI”) and purchased performing loans. PCI loans were identified as those loans that were nonaccrual prior to the business combination and those loans that were identified as potentially impaired. Potentially impaired loans were those loans that were identified during the credit review process where there was an indication that the borrower did not have sufficient cash flows to service the loan in accordance with its terms. Specifically, loans with a risk rating of special mention or worse, loans that had been previously restructured as a troubled debt restructuring (“TDR”), or loans that had a history of delinquent payments were deemed PCI. Performing loans were those loans that were currently performing in accordance with the loan contract and did not exhibit any significant deterioration in credit quality since origination. For loans that were identified as performing, the fair values were determined using a discounted cash flow analysis (the "income approach"). Performing loans were segmented into pools based on loan type including commercial mortgages, multifamily, commercial and industrial, construction and land development, consumer residential, and consumer nonresidential, and further segmented based on payment structure (fully amortizing, non-fully amortizing balloon, or interest only), rate type (fixed versus variable), and remaining maturity. The estimated cash flows expected to be collected for each loan were determined using a valuation model that included the following key assumptions: prepayment speeds, expected credit loss rates, and discount rates. Prepayment speeds were influenced by many factors including, but not limited to, current yields, historic rate trends, payment types, interest rate type, and the duration of the individual loan. Expected credit loss rates were based on recent and historical default and loss rates observed for loans with similar characteristics, and further influenced by a third-party loan review on a selection of loans within the acquired portfolio. The discount rates used were based on rates market participants may require for cash flows with similar risk characteristics at the acquisition date. For loans that were identified as PCI, either the above income approach or the asset approach was used. The income approach was used for PCI loans where there was an expectation that the borrower would more likely than not continue to pay based on the current terms of the loan contract. Management used the asset approach for all nonaccrual loans to reflect market participant assumptions. Under the asset approach, the fair value of each loan was determined based on the estimated fair values of the underlying collateral, less estimated costs to sell. The methods used to estimate the fair values of loans are sensitive to the assumptions and estimates used. While management attempted to use assumptions and estimates that best reflected the acquired loan portfolios and current market conditions, a greater degree of subjectivity is inherent in these values than in those determined in active markets. Premises and equipment. Land and buildings (collectively, “premises”) acquired were recorded at estimated fair value as determined by third-party appraisals at or near the merger date. Equipment, including office furniture, computers, and similar assets, were recorded at the their net book values as of the merger date, which approximated fair value. Bank owned life insurance. The carrying value of bank owned life insurance was deemed to reasonably approximate fair value. These policies are recorded at their cash surrender value, using information provided by the insurance carriers. The following table presents the purchased performing and PCI loans receivable at the date of the Bay Banks Merger and the fair value adjustments (discounts) recorded immediately following the merger. As of January 31, 2021 (Dollars in thousands) Purchased Performing PCI Total Principal payments receivable $ 936,523 $ 111,766 $ 1,048,289 Fair value adjustment - credit and interest ( 2,784 ) ( 15,072 ) ( 17,856 ) Fair value of acquired loans $ 933,739 $ 96,694 $ 1,030,433 Core deposit intangible. Core deposit intangible ("CDI") is the measure of the value of noninterest-bearing checking, savings, interest-bearing checking, money market, and certain certificates of deposits assumed in a business combination. Certificates of deposit with balances over $100,000 and brokered deposits are excluded from evaluation, as the Company determined customer related intangible assets are non-existent for these accounts. The estimated fair value of CDI was based on the present value of the expected cost savings attributable to the core deposit funding relative to an alternative funding source. The CDI is being amortized over an estimated useful life of 10 years, which approximates the existing deposit relationships acquired. Deposits. The fair values of deposit liabilities with no stated maturity (noninterest-bearing checking, savings, interest-bearing checking, and money market deposits) are equal to the carrying amounts payable on demand. The estimated fair value of the certificates of deposit represents contractual cash flows, discounted to present value using interest rates currently offered by market participants on deposits with similar characteristics and remaining maturities. FHLB borrowings. The fair value of the FHLB borrowings was estimated by discounting the future cash flows using current interest rates offered for similar advances as of the acquisition date. FRB borrowings. The fair value of Federal Reserve Bank (“FRB”) borrowings was deemed to approximate its carrying value. These borrowings are pursuant to the FRB’s Paycheck Protection Program Liquidity Facility (“PPPLF”) and there is no comparable borrowing to advances under this facility. Subordinated notes. The fair value of the subordinated notes was estimated by utilizing recent issuance rates for subordinated debt offerings of similar issuer size near the merger date and adjusted for time to redemption or maturity. The fair value estimates are subject to change for up to one year after the effective date of the merger, if additional information relative to effective date fair values becomes available. No adjustments have been made to the fair value estimates through September 30, 2021. Impact of Certain Fair Value Adjustments The net effect of the amortization and accretion of premiums and discounts associated with the fair value adjustments to assets acquired and liabilities assumed in the Bay Banks Merger had the following effect on the consolidated income statements for the three and nine months ended September 30, 2021.

As of September 30, 2021 and December 31, 2020, only investment grade securities were in an unrealized loss position or the amount of unrealized loss for the security was not significant. Investment securities with unrealized losses are generally a result of pricing changes due to recent changes in the current interest rate environment and not as a result of permanent credit impairment. Contractual cash flows for the mortgage-backed securities are guaranteed and/or funded by the U.S. government. Municipal securities show no indication that the contractual cash flows will not be received when due. The Company does not intend to sell nor does it believe that it will be required to sell any of its temporarily impaired securities prior to the recovery of the amortized cost. Restricted equity investments consisted of stock in the FHLB (carrying value of $ 6.0 million and $ 5.8 million as of September 30 , 2021 and December 31, 2020, respectively), FRB stock (carrying value of $ 4.9 million and $ 2.2 million as of September 30 , 2021 and December 31, 2020, respectively), and stock in the Company’s correspondent bank (carrying value of $ 468 thousand and $ 248 thousand as of September 30 , 2021 and December 31, 2020, respectively). Restricted equity investments are carried at cost. The Company also has various other equity investments, including shares in other financial institutions and fintech companies, totaling $ 7.9 million and $ 3.0 million as of September 30 , 2021 and December 31, 2020, respectively, which are carried at fair value with any gain or loss reported in the consolidated income statements each reporting period. The Company also holds investments in early-stage focused investment funds, small business investment companies ("SBIC"), and low-income housing partnerships, which are reported in other investments on the consolidated balance sheets.

Loans and Allowance for Loan Losses	Note 5 – Loans and Allowance for Loan Losses The following table presents loans held for investment, including Paycheck Protection Program ("PPP") loans, as of the dates stated. (Dollars in thousands) September 30, 2021 December 31, 2020 Commercial and industrial $ 309,058 $ 123,675 Paycheck Protection Program 47,325 292,068 Real estate – construction, commercial 139,286 54,702 Real estate – construction, residential 51,098 18,040 Real estate – mortgage, commercial 680,309 273,499 Real estate – mortgage, residential 499,361 213,404 Real estate – mortgage, farmland 6,317 3,615 Consumer 67,787 46,684 Gross loans 1,800,541 1,025,687 Less: Deferred loan fees, net of costs ( 1,440 ) ( 4,271 ) Total $ 1,799,101 $ 1,021,416 In 2020, the Company participated in the PPP under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) (“PPP 1”). Through the PPP 1, the federal government partnered with banks, including the Bank, to provide over $ 650 billion to small businesses to support payrolls and other operating expenses. PPP 1 loans have a two-year term if originated prior to June 5, 2020, or a five-year term if originated on or subsequent to June 5, 2020, and earn an annual interest rate of 1 %. Banks originating PPP 1 loans earned a processing fee of 1 %, 3 %, or 5 % of the loan amount, depending on the size of the loan. The Company originated approximately $ 363.4 million in PPP 1 loans in 2020, and as of September 30, 2021, $ 32.6 million of PPP 1 loans were outstanding, including those acquired in the Bay Banks Merger. In 2021 the Company participated in the PPP pursuant to the Economic Aid Act, passed into law on December 27, 2020 (“PPP 2”). The PPP 2 was for applications received by May 31, 2021. The Company funded over 20,000 PPP 2 loans for approximately $ 730 million. PPP 2 loans have a contractual term of five years and earn an annual interest rate of 1 %. Banks originating PPP 2 loans earned processing fees that were tiered depending on the size of the loan. Specifically, processing fees for loans of not more than $ 50,000 equaled 50 % of the loan balance or $ 2,500 , whichever was less; processing fees for loans more than $ 50,000 and not more than $ 350,000 equaled 5 % of the loan balance, and processing fees for loans above $ 350,000 equaled 3 % of the loan balance. Of the PPP 2 loans originated in 2021, approximately 19,500 with principal balances of $ 712.6 million were sold on June 28, 2021. Gross proceeds from the sale were $ 705.9 million and the Company recorded a pre-tax gain in noninterest income of $ 24.3 million on the sale after giving effect to $ 30.9 million of unamortized fees, net of deferred costs, and the sale discount. As of September 30, 2021, the Company held PPP 2 loans with aggregate principal balances and unamortized fees, net of deferred costs, of $ 14.7 million and $ 676 thousand, respectively. The Company believes that the majority of PPP 1 and PPP 2 loans will be forgiven, in accordance with the terms of the program, and will be paid in full pursuant to the U.S. government guarantee. The Company is accounting for the PPP processing fees in accordance with ASC 310-20, Receivables - Nonrefundable Fees and Other Costs, which requires fees, net of costs, to be deferred and amortized as a component of loan yield over the expected life of the loans, which the Company believes is 1.5 years for PPP 1 loans and one to three years for PPP 2 loans, depending on the individual loan balance. Of the $ 11.5 million of processing fees received in 2020 for PPP 1 loans, approximately $ 0 of unamortized fees remain as of September 30, 2021, with $ 228 thousand and $ 4.8 million recognized as a component of interest income for the three and nine months ended September 30, 2021, respectively. PPP 2 processing fees, net of costs, totaled $ 40.8 million through the first nine months of 2021, of which $ 484 thousand and $ 12.1 million were recognized as interest income for the three and nine months ended September 30, 2021, respectively, and $ 30.9 million was recognized as part of the gain on sale in the second quarter of 2021. From the onset of the global COVID-19 pandemic, the Company has proactively addressed the needs of its commercial and individual borrowers by modifying loans allowing for the short-term deferral of principal payments or of principal and interest payments. Pursuant to the CARES Act and the Economic Aid Act, banks have the option to temporarily suspend certain requirements of GAAP related to TDRs to the earlier of January 1, 2022 or the date that is 60 days after the date on which the national emergency terminates if certain conditions are met. All loan modifications made by the Company were made on a good faith basis to borrowers who met the requirements for modifications under the CARES Act. As a result of regulatory and accounting guidance regarding such modifications, the loans were not designated as TDRs as of September 30, 2021 and December 31, 2020. In response to the COVID-19 pandemic, during 2020, the Company approved over 550 loan deferrals for a total of $ 110.6 million. In addition, Bay Banks approved nearly 400 loan deferrals for approximately $ 160.0 million. Most of these loans are now past the deferment period and are back on normal payment schedules, and as of September 30, 2021, 16 loans were in deferment for a total of approximately $ 4.7 million. The Company has pledged certain commercial and residential mortgages as collateral for borrowings with the FHLB. Loans totaling $ 517.6 million and $ 213.3 million were pledged as of September 30, 2021 and December 31, 2020, respectively. Additionally, PPP loans were pledged as collateral for PPPLF advances in the amount of $ 33.9 million and $ 281.6 million as of September 30, 2021 and December 31, 2020, respectively. As a result of the Bay Banks Merger and the 2019 acquisition of Virginia Community Bankshares, Inc., the acquired loan portfolios were initially measured at fair value as of the respective acquisition dates and subsequently accounted for as either purchased performing loans or PCI loans.

The ALL is increased through a provision for loan losses charged against income and decreased by loans charged-off (net of recoveries, if any). Management’s periodic evaluation of the adequacy of the ALL is based on past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, and current economic conditions. While management uses the best information available to make evaluations, future adjustments may be necessary, if economic or other conditions differ substantially from the assumptions used. The ALL consists of specific and general components. The specific component relates to loans that are identified as impaired, which generally include loans risk rated substandard or worse with balances of $ 500 thousand or more and all loans classified as TDRs. For loans that are classified as impaired, an allowance is established when the discounted cash flows or the net realizable value of underlying collateral, which is equal to the estimated fair value less estimated costs to sell, of the impaired loan is lower than the carrying value of that loan. The general component covers those loans not classified as impaired and those loans classified as impaired that are not individually evaluated for impairment and is based on historical loss experience adjusted for other internal or external influences on credit quality that are not fully reflected in the historical data. The Company follows applicable guidance issued by the FASB, which requires that losses be accrued when they are probable of occurring and can be estimated. It also requires that impaired loans, within its scope, be measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, except that as a practical expedient, a creditor may measure impairment based on a loan’s observable market price, or the fair value of the underlying collateral if the loan is collateral dependent. PPP loans are fully guaranteed by the U.S. government; therefore, the Company recorded no ALL for these loans as of September 30, 2021 and December 31, 2020. In future periods, the Company may be required to establish an ALL for these loans, which would result in a provision for loan losses charged to earnings. The following tables present a summary of the loan portfolio individually and collectively evaluated for impairment as of the dates stated.

These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions. Certain TDRs are classified as non-performing at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months. The Company had four TDRs totaling $ 235 thousand as of September 30, 2021, two of which were classified as TDRs due to a change in interest rate and payment terms and two of which were classified as TDRs due to a change in payment terms. The Company had two TDRs totaling $ 142 thousand as of December 31, 2020, one of which was classified as a TDR due to a change in interest rate and payment terms and the other loan was classified as a TDR due to a change in payment terms.

Goodwill and Other Intangibles	Note 6 – Goodwill and Other Intangibles Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized but tested for impairment at least annually or more frequently if events and circumstances exist that indicate that a goodwill impairment test should be performed. Intangible assets with definite useful lives are amortized over their estimated useful lives, which range from 5 to 12 years. Goodwill is the only intangible asset with an indefinite life on the consolidated balance sheets. As of September 30, 2021 and December 31, 2020, the Company's goodwill totaled $ 26.8 million and $ 19.6 million, respectively.

Included in other amortizable intangibles were loan servicing assets of $ 258 thousand and $ 209 thousand at September 30, 2021 and December 31, 2020, respectively, related to the sale of the government guaranteed portion of certain loans that the Company continues to service. Loan servicing assets of $ 131 thousand and $ 189 thousand were added during the nine months ended September 30, 2021 and the year ended December 31, 2020, respectively. The amortization of these intangibles is included in interest and fees on loans in the consolidated statement of income. The Company retains servicing rights on mortgages originated and sold to the secondary market. The Company records mortgage servicing rights (“MSR”) assets initially at fair value and subsequently accounts for them under the amortization method, pursuant to which an impairment assessment is performed each reporting period. The amortization method requires that the MSR assets be recorded at the lower of cost or fair value. As of September 30, 2021 and December 31, 2020, the carrying value of MSR assets were $ 15.0 million and $ 7.1 million, respectively.

Borrowings	Note 8 – Borrowings FHLB Borrowings The Bank has a borrowing facility from the FHLB secured by certain real estate loans and pledged securities. The FHLB will lend up to 30 % of the Bank’s total assets as of the prior quarter end, subject to certain eligibility requirements, including adequate collateral. Total lendable collateral was $ 392.2 million as of September 30, 2021. The Bank had borrowings from the FHLB that totaled $ 125.1 million and $ 115.0 million as of September 30, 2021 and December 31, 2020, respectively. Of these advances, the Company assumed $ 10.1 million in the Bay Banks Merger. The borrowings also required the Bank to own $ 6.0 million and $ 5.8 million of FHLB stock, as of September 30, 2021 and December 31, 2020, respectively, which is included in restricted equity and other investments on the consolidated balance sheets.

The Company exercised its right to redeem the 2025 Bay Banks Notes in the third quarter of 2021 and repaid the 2025 Bay Banks Notes in full. On May 28, 2020, the Company issued a subordinated note with a principal amount of $ 15.0 million which matures on June 1, 2030 (the “2030 Note”). The 2030 Note is an unsecured, subordinated obligation of the Company and ranks junior in right of payment to the Company’s existing and future senior indebtedness and ranks in parity with the other subordinated notes issued by the Company. Beginning on June 1, 2025 through maturity, the 2030 Note may be redeemed, at the Company's option, on any scheduled interest payment date. The aggregate carrying value of the 2030 Note, including capitalized, unamortized debt issuance costs, was $ 14.7 million as of September 30, 2021. For both the three and nine months ended September 30, 2021, the effective interest rate on the 2020 Note was 6.12 %. On November 20, 2015, the Company issued an aggregate of $ 10.0 million of subordinated notes with a maturity date of December 1, 2025 (the “2025 Notes”). The 2025 Notes could be redeemed in part or in full at any interest payment date on or after December 1, 2020, at the option of the Company. The Company exercised its right to redeem the 2025 Notes in the second quarter of 2021 and repaid the 2025 Notes in full.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Note 9 – Derivatives The Company enters into interest rate swap agreements to facilitate the risk management strategies to accommodate the needs of its banking customers. The Company mitigates the risk of entering into these interest rate swap agreements by entering into equal and offsetting swap agreements with highly-rated third-party financial institutions. These back-to-back interest rate swap agreements are free-standing derivatives and are recorded at fair value in the consolidated balance sheets (asset positions are included in other assets and liability positions are included in other liabilities). The following tables present the notional and fair value of interest rate swap agreements recorded as other assets and other liabilities on the Company’s consolidated balance sheets as of the dates stated. September 30, 2021 (Dollars in thousands) Notional Fair Interest rate swap agreement Receive fixed/pay variable swaps $ 2,064 $ 224 Pay fixed/receive variable swaps 2,064 ( 224 ) December 31, 2020 (Dollars in thousands) Notional Fair Interest rate swap agreement Receive fixed/pay variable swaps $ 2,100 $ 339 Pay fixed/receive variable swaps 2,100 ( 339 ) The Company entered into various cash flow hedges as defined by ASC 815-20, Derivatives and Hedging. The objective of these interest rate swap agreements was to hedge the risk of variability in the Company’s cash flows attributable to changes in the 3-month LIBOR index rate component of forecasted three-month fixed rate funding advances from the FHLB. The hedging objective was to reduce the interest rate risk associated with the Company’s fixed rate advances from the designation date and through the maturity date. The identified hedge layers are presented in the following table (in thousands). Each hedge layer has a variable receive leg of 3-month LIBOR and a pay fixed leg of 1.80 %. 3-Month LIBOR Hedged Notional Exposure Hedged From To $ 15,000 $ 15,000 July 1, 2019 July 1, 2022 $ 25,000 $ 25,000 August 2, 2019 February 2, 2023 $ 10,000 $ 10,000 August 29, 2019 August 29, 2023 At the time the hedges identified in the table above expire, new hedges will begin. These new hedges are summarized in the following table (in thousands). Each hedge layer has a variable receive leg of 3-month LIBOR and a pay fixed leg ranging from 0.92 % to 0.95 %. 3-Month LIBOR Hedged Notional Exposure Hedged From To $ 15,000 $ 15,000 July 1, 2022 July 1, 2032 $ 25,000 $ 25,000 February 2, 2023 February 2, 2033 $ 10,000 $ 10,000 August 29, 2023 August 29, 2033 Beginning in 2020, the Company entered into three additional hedges summarized in the following table (in thousands). Each hedge layer has a variable receive leg of 3-month LIBOR and a pay fixed leg ranging from 0.83 % to 0.86 %. 3-Month LIBOR Hedged Notional Exposure Hedged From To $ 20,000 $ 20,000 March 13, 2020 March 13, 2030 $ 35,000 $ 35,000 May 6, 2020 May 6, 2027 $ 10,000 $ 10,000 May 29, 2020 May 29, 2027 The Company has the intent and ability to fund the 3-month rate advances during the term of these cash flow hedges. Interest rate swap assets and liabilities were $ 5.8 million and $ 1.2 million, respectively, as of September 30, 2021, and $ 1.7 million and $ 2.7 million, respectively, as of December 31, 2020. The Company had cash collateral with the counterparties of $ 6.0 million included within other assets on the consolidated balance sheets as of September 30, 2021 and December 31, 2020. The Bank also participates in a “mandatory” delivery program for its government guaranteed and conventional mortgage loans held for sale. Under the mandatory delivery program, loans with interest rate locks are paired with the sale of a to-be-announced mortgage-backed security bearing similar attributes. Under the mandatory delivery program, the Bank commits to deliver loans to an investor at an agreed upon price after the close of such loans. This differs from a “best efforts” delivery, which sets the sale price with the investor on a loan-by-loan basis when each loan is locked. The Bank had entered into $ 93.7 million and $ 154.3 million of rate lock commitments with borrowers, net of expected fallout, as of September 30, 2021 and December 31, 2020, respectively, and $ 144.5 million and $ 97.1 million of closed loan inventory waiting for sale, which were hedged by $ 241.6 million and $ 225.0 million in forward to-be-announced mortgage-backed securities as of September 30, 2021 and December 31, 2020, respectively. Mortgage derivative assets totaled $ 3.5 million and $ 5.3 million as of September 30, 2021 and December 31, 2020, respectively, and mortgage derivative liabilities, which are included in other liabilities on the consolidated balance sheets, were $ 0 and $ 1.6 million as of September 30, 2021 and December 31, 2020, respectively.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Note 10 – Stock-Based Compensation The Company has granted restricted stock awards to employees and directors under the Company’s 2017 Equity Incentive Plan. The restricted stock awards are considered fixed awards as the number of shares and fair value is known at the date of grant, and the fair value of the award at the grant date is amortized over the requisite service period. Compensation expense recognized in the consolidated statements of income related to restricted stock awards, net of forfeitures, was $ 511 thousand and $ 848 thousand for the three and nine months ended September 30, 2021, respectively, and was $ 199 thousand and $ 331 thousand for the three and nine months ended September 30, 2020, respectively. On July 1, 2021, the Company granted restricted stock awards relating to 173,484 shares of the Company's common stock to employees and directors. At September 30, 2021, restricted stock awards relating to 237,785 shares of the Company’s common stock were outstanding and unrecognized compensation expense related to the restricted stock awards at September 30, 2021 totaled $ 3.1 million. The Company converted fully vested options to purchase 198,362 shares of Bay Banks common stock into options to purchase 99,176 shares ( 148,764 on a post Stock Split basis) of the Company’s common stock pursuant to the Bay Banks Merger. The estimated fair value of the converted stock options as of the effective date of the merger was $ 472 thousand and included in the Bay Banks Merger consideration. The estimated fair value of $ 472 thousand was determined using the Black-Scholes Model, which requires the use of assumptions including the risk-free interest rate, expected term, expected volatility (of the underlying stock), and expected dividend yield. The following table presents the ranges and weighted averages of assumptions used to determine the estimated fair value of the converted stock options in the Bay Banks Merger. As of January 31, 2021 Range Weighted-average Risk free interest rate (U.S. Treasury) 0.06 % - 0.45 % 0.32 % Expected term (years) 0.14 - 5.00 3.89 Expected volatility 21.2 % - 38.2 % 32.8 % Expected dividend yield 2.85 % 2.85 % The weighted-average exercise price and remaining contractual life (in years) of the stock options as of the date of the Bay Banks Merger was $ 14.83 per stock option ($ 9.89 on a post Stock Split basis) and 5.47 years, respectively. During the nine months ended September 30, 2021, 83,647 and 380 stock options were exercised and forfeited, respectively, resulting in 64,737 options outstanding as of September 30, 2021.

Fair Value Disclosures [Abstract]
Fair Value	Note 11 – Fair Value The fair value of a financial instrument is the current amount that would be exchanged between willing parties in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The Company records fair value adjustments to certain assets and liabilities and determines fair value disclosures utilizing a definition of fair value of assets and liabilities that states that fair value 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. Additional considerations are involved to determine the fair value of financial assets in markets that are not active. The Company uses 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: Securities Where quoted prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities would include highly liquid government bonds, mortgage products and exchange traded equities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics, or discounted cash flow. Level 2 securities would include U.S. agency securities, mortgage-backed agency securities, obligations of states and political subdivisions and certain corporate, asset backed and other securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within Level 3 of the valuation hierarchy. The carrying value of restricted FRB and FHLB stock approximates fair value based upon the redemption provisions of each entity and is therefore excluded from the following table. Rabbi trust assets As a result of the Bay Banks Merger, the Company acquired and assumed a rabbi trust and deferred compensation plan. The assets held by the rabbi trust are invested at the direction of the individual participants and are generally invested in marketable investment securities, such as common stocks and mutual funds or short-term investments (e.g., cash) (Level 1). Rabbi trust assets and the associated deferred compensation plan liability are included in other assets and other liabilities, respectively, in the consolidated balance sheets. Derivative financial instruments Derivative instruments used to hedge residential mortgage loans held for sale and the related interest rate lock commitments include forward commitments to sell mortgage loans and are reported at fair value utilizing Level 2 inputs. The fair values of derivative financial instruments are based on derivative market data inputs as of the valuation date and the underlying value of mortgage loans for rate lock commitments. Cash flow hedges (interest rate swaps) hedge against the risk of variability in cash flows attributable to changes in the 3-month LIBOR index rate component of forecasted 3-month fixed rate funding advances from the FHLB. These cash flow hedges are recorded at fair value utilizing Level 2 inputs. The following tables present the balances of financial assets measured at fair value on a recurring basis as of the dates stated. September 30, 2021 (Dollars in thousands) Total Level 1 Level 2 Level 3 Securities available for sale State and municipals $ 41,852 $ — $ 41,852 $ — U.S. Treasury and agencies 48,548 — 48,548 — Mortgage backed securities 238,923 — 238,923 — Corporate bonds 30,775 — 30,775 — Total securities available for sale $ 360,098 $ — $ 360,098 $ — Other assets Rabbi trust assets $ 963 $ 963 $ — $ — Mortgage derivative asset 3,456 — 3,456 — Interest rate swap asset 5,838 — 5,838 — Other liabilities Mortgage derivative liability $ — $ — $ — $ — Interest rate swap liability 1,239 — 1,239 — December 31, 2020 (Dollars in thousands) Total Level 1 Level 2 Level 3 Securities available for sale State and municipals $ 14,259 $ — $ 14,259 $ — U.S. Treasury and agencies 2,409 — 2,409 — Mortgage backed securities 72,635 — 72,635 — Corporate bonds 20,172 — 20,172 — Total securities available for sale $ 109,475 $ — $ 109,475 $ — Other assets Mortgage derivative asset $ 5,293 $ — $ 5,293 $ — Interest rate swap asset 1,716 — 1,716 — Other liabilities Mortgage derivative liability $ 1,569 $ — $ 1,569 $ — Interest rate swap liability 2,735 — 2,735 — Certain financial assets are measured at fair value on a nonrecurring basis in accordance with GAAP. Adjustments to the fair value of these assets usually result from the application of lower-of-cost-or-market accounting or write-downs of individual assets. The following describes the valuation techniques used by the Company to measure certain financial assets recorded at fair value on a nonrecurring basis in the financial statements. Mortgage Servicing Rights The Company records MSR assets initially at fair value and subsequently accounts for them under the amortization method and performs an impairment assessment each reporting period. The amortization method requires that the MSR assets be recorded at the lower of cost or fair value. The following tables present the change in MSR assets using Level 3 inputs as of and for the periods stated. (Dollars in thousands) MSR Assets Balance, December 31, 2020 $ 7,084 Acquired in Bay Banks Merger 997 Additions 9,252 Write-offs ( 616 ) Amortization ( 1,741 ) Impairments — Fair value adjustments 3,567 Balance, September 30, 2021 - fair value $ 18,543 Balance, September 30, 2021 - amortized cost $ 14,976 (Dollars in thousands) MSR Assets Balance, December 31, 2019 $ — Additions 7,539 Write-offs ( 61 ) Amortization ( 391 ) Impairments ( 3 ) Fair value adjustments 207 Balance, December 31, 2020 - fair value $ 7,291 Balance, December 31, 2020 - amortized cost $ 7,084 A third-party model is used to determine the fair value of the Company’s MSR assets. The model establishes pools of performing loans, calculates projected future cash flows for each pool, and applies a discount rate to each pool. As of September 30, 2021 and December 31, 2020, the Company was servicing approximately $ 1.75 billion and $ 846.5 million of loans, respectively. Loans are segregated into homogenous pools based on loan term, interest rates, and other similar characteristics. Cash flows are then estimated based on net servicing fee income and utilizing assumed servicing costs and prepayment speeds. The weighted average net servicing fee income of the portfolio was 28.1 basis points as of September 30, 2021. Estimated base annual servicing costs were $ 65.00 to $ 80.00 per loan depending on the guarantor. Prepayment speeds in the model are based on empirically derived data for mortgage pool factors and differences between a mortgage pool’s weighted average coupon and its current mortgage rate. The weighted average prepayment speed assumption used in the fair value model was 12.16 % as of September 30, 2021. A base discount rate of 9.0 % to 12.0 % ( 9.30 % weighted average discount rate) was then applied to each pool’s projected future cash flows as of September 30, 2021. The discount rate is intended to represent the estimated market yield for the highest quality grade of comparable servicing. MSR assets are classified as Level 3. Impaired Loans Loans are designated as impaired when, in the judgment of management based on current information and events, it is probable that all amounts due will not be collected according to the contractual terms of the loan agreement. The measurement of loss associated with impaired loans can be based on either the discounted cash flows of the loan or the fair value of the collateral, if any, less estimated costs to sell, if the loan is collateral dependent. Collateral may be in the form of real estate or business assets including equipment, inventory, and accounts receivable. Any given loan may have multiple types of collateral; however, the majority of the Company’s loan collateral is real estate. The value of real estate collateral is generally determined utilizing a market valuation approach based on an appraisal conducted by an independent, licensed appraiser using observable market data (Level 2). If the collateral value is significantly adjusted due to differences in the comparable properties or is discounted because of lack of marketability, then the fair value is considered Level 3. The value of business equipment is based upon an outside appraisal if deemed significant or the net book value based on the borrower’s financial statements if not considered significant. Likewise, values for inventory and accounts receivables collateral are based on financial statements or aging reports (Level 3). Fair value adjustments are recorded in the period incurred as provision for loan losses on the consolidated statements of income. Loans Held for Sale Mortgage loans originated or purchased and intended for sale in the secondary market are carried at estimated market value in the aggregate. The agreed upon sales price is considered fair value as all of these loans are under agreements to sell to investors at the time of origination. This amount is generally the loan’s principal amount. Changes in fair value are recognized in the gain on sale of mortgages on the consolidated statements of income. Other Real Estate Owned Certain assets such as OREO are measured at fair value less estimated costs to sell. Valuation of OREO is generally determined using current appraisals from independent appraisers, a Level 2 input. If current appraisals cannot be obtained prior to reporting dates, or if declines in value are identified after a recent appraisal is received, appraisal values are discounted, resulting in Level 3 estimates. If the Company markets the property with a real estate agent or broker, estimated selling costs reduce the listing price, resulting in a valuation based on Level 3 inputs. The following tables summarize assets that were measured at fair value on a nonrecurring basis as of the dates stated. September 30, 2021 (Dollars in thousands) Total Level 1 Level 2 Level 3 Impaired loans, net $ 8,233 $ — $ — $ 8,233 Loans held for sale 144,111 — 144,111 — OREO 227 — — 227 December 31, 2020 (Dollars in thousands) Total Level 1 Level 2 Level 3 Impaired loans, net $ 2,187 $ — $ — $ 2,187 Loans held for sale 148,209 — 148,209 — The following tables present quantitative information about Level 3 fair value measurements as of the dates stated. Balance as of Valuation Unobservable Weighted (Dollars in thousands) September 30, 2021 Technique Input Average Impaired loans, net $ 8,233 Discounted appraised value Selling costs 7 % OREO 227 Discounted appraised value Selling costs 7 % Balance as of Valuation Unobservable Weighted (Dollars in thousands) December 31, 2020 Technique Input Average Impaired loans, net $ 2,097 Discounted appraised value Selling costs 10 % 90 Discounted cash flows Discount rate 6 % Fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practical to estimate the value is based upon the characteristics of the instruments and relevant market information. Financial instruments include cash, evidence of ownership in an entity, or contracts that convey or impose on an entity that contractual right or obligation to either receive or deliver cash for another financial instrument. The information used to determine fair value is highly subjective and judgmental in nature and, therefore, the results may not be precise. Subjective factors include, among other things, estimates of cash flows, risk characteristics, credit quality, and interest rates, all of which are subject to change. Since the fair value is estimated as of the balance sheet date, the amounts that will actually be realized or paid upon settlement or maturity on these various instruments could be significantly different. The carrying values of cash and due from banks and federal funds sold are of such short duration that carrying value reasonably approximates fair value (Level 1). The carrying values of accrued interest receivable and accrued interest payable are of such short duration that carrying value reasonably approximates fair value (Level 2). The carrying value of restricted equity investments approximates fair value based on the redemption provisions of the issuer (Level 2). The fair value of the Company’s loan portfolio includes a credit risk assumption in the determination of the fair value of its loans. This credit risk assumption is intended to approximate the fair value that a market participant would realize in a hypothetical orderly transaction. The Company’s loan portfolio is initially fair valued using a segmented approach. The Company divides its loan portfolio into the following categories: variable rate loans, impaired loans, and all other loans. The results are then adjusted to account for credit risk as described above. The fair value of the Company’s loan portfolio also considers illiquidity risk through the use of a discounted cash flow model to compensate for based on certain assumptions included within the discounted cash flow model, primarily the use of discount rates that better capture inherent credit risk over the lifetime of a loan. This consideration of both credit risk and illiquidity risk provides an estimated exit price for the Company’s loan portfolio. Loans held for investment are reported as Level 3. There is no credit risk associated with PPP loans as they are fully guaranteed by the U.S. government. Further, the Company believes the PPP loans will be forgiven within 1.5 years for PPP 1 loans and between one and three years for PPP 2 loans, depending on the loan’s balance, and any fair value adjustment for potential interest rate change was considered inconsequential as of September 30, 2021. As a result, the carrying value of PPP loans reasonably approximates fair value (Level 3). The carrying value of cash surrender value of life insurance reasonably approximates fair value. The Company records these policies at their cash surrender value, which is estimated using information by insurance carriers (Level 2). The carrying value of noninterest-bearing deposits approximates fair value (Level 1). The carrying values of interest-bearing demand, money market, and savings deposits approximates fair value based on their current pricing and are reported as Level 2. The fair value of certificates of deposits were valued using a discounted cash flow calculation that includes a market rate analysis of the current rates offered by market participants for certificates of deposits that mature in the same period. Time deposits are reported as Level 3. The fair value of the FHLB borrowings is estimated by discounting the future cash flows using current interest rates offered for similar advances (Level 2). The fair value of FRB borrowings was approximated as its carrying value as there is no comparable debt to PPPLF advances (Level 2). The fair value of the Company’s subordinated notes was estimated by utilizing recent issuance rates for subordinated debt offerings of similar issuer size (Level 3). The Company assumes interest rate risk (the risk that general interest rate levels will change) as a result of its normal operations. As a result, the fair values of the Company’s financial instruments will change when interest rate levels change, and these changes 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. Borrowers with fixed rate obligations, however, are less likely to prepay in a rising rate environment and more likely to prepay in a falling rate environment. Conversely, depositors who are receiving fixed rates are more likely to withdraw funds before maturity in a rising rate environment and less likely to do so in a falling rate environment. Management monitors rates and maturities of assets and liabilities and attempts to minimize interest rate risk by adjusting terms of new loans and deposits and by investing in securities with terms that mitigate the Company’s overall interest rate risk. The following tables present the estimated fair values, related carrying amounts, and valuation level of the financial instruments as of the dates stated.

Leases [Abstract]
Leases	Note 12 – Leases Lease liabilities represent the Company’s obligation to make lease payments and are presented at each reporting date as the net present value of the remaining contractual cash flows. Cash flows are discounted at the Company’s incremental borrowing rate in effect at the commencement date of the lease. Right-of-use assets represent the Company’s right to use the underlying asset for the lease term and are calculated as the sum of the lease liability and if applicable, prepaid rent, initial direct costs, and any incentives received from the lessor. The Company’s long-term lease agreements are classified as operating leases. Certain of these leases offer the option to extend the lease term and such extensions are included in the calculation of the lease liabilities to the extent the options are reasonably assured of being exercised. The lease agreements do not provide for residual value guarantees and have no restrictions or covenants that would impact dividends or require incurring additional financial obligations. The Company assumed five operating leases for real estate in the Bay Banks Merger. In accordance with ASC 842–Leases, the original classification of each lease was retained and not re-evaluated as part of the accounting for the business combination.

Minimum Regulatory Capital

Minimum Regulatory Capital	9 Months Ended

Regulatory Matters [Abstract]
Minimum Regulatory Capital	Note 13 – Minimum Regulatory Capital Banks and bank holding companies are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Company's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, financial institutions must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. A financial institution's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. The final rules implementing Basel Committee on Banking Supervision's capital guidelines for U.S. banks (the “Basel III rules”) became effective for the Bank on January 1, 2015 with full compliance with all of the requirements phased-in over a multi-year schedule and fully phased-in at January 1, 2019. Under the Basel III rules, the Bank must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios of 2.50 % for all ratios, except the tier 1 leverage ratio. If a banking organization dips into its capital conservation buffer, it is subject to limitations on certain activities, including payment of dividends, share repurchases, and discretionary compensation to certain officers. Management believes as of September 30, 2021 and December 31, 2020, the Bank met all capital adequacy requirements to which it is subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized; although, these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At September 30, 2021, the most recent regulatory notification categorized the Bank as well capitalized under the regulatory framework. There are no conditions or events since that notification that management believes have changed the institution's category. The following tables present the capital and capital ratios to which the Bank is subject and the amounts and ratios to be adequately and well capitalized as of the dates stated. Adequately capitalized ratios include the conversation buffer.

Commitments and Contingencies

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Commitments and Contingencies	Note 14 – Commitments & Contingencies In the ordinary course of operations, the Company is party to legal proceedings. Based upon information currently available, management believes that such legal proceedings, in the aggregate, will not have a material adverse effect on the Company’s business, financial condition, results of operations, or cash flows. Also, in the ordinary course of operations, the Company offers various financial products to its customers to meet their credit and liquidity needs. These instruments involve elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and stand-by letters of credit written is represented by the contractual amount of these instruments. The Company uses the same credit policies in making commitments and conditional commitments as it does for on-balance sheet commitments. Subject to its normal credit standards and risk monitoring procedures, the Company makes contractual commitments to extend credit. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. Since many of the commitments may expire without being completely drawn upon, the total commitment amounts do not necessarily represent future cash requirements. As of September 30, 2021 and December 31, 2020, the Company had outstanding loan commitments of $ 384.9 million and $ 126.0 million, respectively. Conditional commitments are issued by the Company in the form of performance stand-by letters of credit, which guarantee the performance of a customer to a third party. As of September 30, 2021 and December 31, 2020, commitments under outstanding performance stand-by letters of credit totaled $ 655 thousand and $ 0 , respectively. Additionally, the Company issues financial stand-by letters of credit, which guarantee payment to the underlying beneficiary (i.e., third party) if the customer fails to meet its designated financial obligation. As of September 30, 2021 and December 31, 2020, commitments under outstanding financial stand-by letters of credit totaled $ 3.6 million and $ 6.1 million, respectively. The credit risk of issuing stand-by letters of credit is essentially the same as that involved in extending loans to customers. Reserves for unfunded commitments to borrowers as of September 30, 2021 and December 31, 2020 were $ 512 thousand and $ 0 , respectively, and are included in other liabilities on the consolidated balance sheets. The Company invests in various partnerships and limited liability companies, many of which invest in early-stage companies operating in fintech businesses. Pursuant to these investments, the Company commits to an investment amount that may be fulfilled in future periods. At September 30, 2021, the Company has future commitments outstanding totaling $ 9.1 million related to these investments.

Earnings Per Share [Abstract]
Earnings Per Share	Note 15 – Earnings Per Share The following table shows the calculation of basic and diluted EPS and the weighted average number of shares outstanding used in computing EPS and the effect on the weighted average number of shares outstanding of dilutive potential common stock. Basic EPS amounts are computed by dividing net income (the numerator) by the weighted average number of common shares outstanding (the denominator). Diluted EPS amounts assume the conversion, exercise, or issuance of all potential common stock instruments, unless the effect would be to reduce the loss or increase earnings per common share. Potential dilutive common stock instruments include exercisable stock options, including those converted and assumed in the Bay Banks Merger. For the three and nine months ended September 30, 2021, stock options for 0 and 433 shares of the Company’s common stock, respectively, were not included in the computation of diluted earnings per share because their effects would have been anti-dilutive. Weighted average common shares outstanding, basic and dilutive, for all periods presented are presented on a post Stock Split basis. For the three months ended For the nine months ended (Dollars in thousands, except per share data) September 30, 2021 September 30, 2020 September 30, 2021 September 30, 2020 Net income $ 6,806 $ 5,059 $ 39,685 $ 12,117 Net loss (income) attributable to noncontrolling interest 4 4 ( 1 ) ( 1 ) Net income available to common shareholders $ 6,810 $ 5,063 $ 39,684 $ 12,116 Weighted average common shares outstanding, basic 18,776,014 8,577,932 17,526,055 8,521,395 Effect of dilutive securities 22,711 — 9,341 — Weighted average common shares outstanding, dilutive 18,798,725 8,577,932 17,535,396 8,521,395 Basic and diluted earnings per common share $ 0.36 $ 0.59 $ 2.26 $ 1.42

Loss Contingency [Abstract]
Legal Matters	Note 18 – Legal Matters On August 12, 2019, a former employee of Virginia Community Bankshares, Inc. (“VCB”) and participant in its Employee Stock Ownership Plan (the “VCB ESOP”) filed a class action complaint against VCB, Virginia Community Bank, and certain individuals associated with the VCB ESOP in the U.S. District Court for the Western District of Virginia, Charlottesville Division. The complaint alleges, among other things, that the defendants breached their fiduciary duties to VCB ESOP participants in violation of the Employee Retirement Income Security Act of 1974, as amended. The complaint alleges that the VCB ESOP incurred damages “that approach or exceed $ 12 million.” The Company automatically assumed any liability of VCB in connection with this litigation as a result of its 2019 acquisition of VCB. The outcome of this litigation is uncertain, and the plaintiff and other individuals may file additional lawsuits related to the VCB ESOP. The Company believes the claims are without merit and no loss has been accrued for this lawsuit. On June 24, 2021, a customer of the Bank filed a purported class action complaint against the Bank in the U.S. District Court for the Western District of Virginia, Harrisonburg Division. The complaint alleged, among other things, that the Bank breached its contract with checking account customers by charging improper overdraft fees, and was seeking monetary damages, restitution, and declaratory relief arising from the alleged assessment and collection of such fees. The complaint also alleged that the aggregate claims of the putative class members exceed $ 5 million. The Company settled this lawsuit for a nominal amount in the third quarter of 2021.

Earnings Per Share [Abstract]
Summary of Computation of Basic and Diluted EPS	The following table shows the calculation of basic and diluted EPS and the weighted average number of shares outstanding used in computing EPS and the effect on the weighted average number of shares outstanding of dilutive potential common stock. Basic EPS amounts are computed by dividing net income (the numerator) by the weighted average number of common shares outstanding (the denominator). Diluted EPS amounts assume the conversion, exercise, or issuance of all potential common stock instruments, unless the effect would be to reduce the loss or increase earnings per common share. Potential dilutive common stock instruments include exercisable stock options, including those converted and assumed in the Bay Banks Merger. For the three and nine months ended September 30, 2021, stock options for 0 and 433 shares of the Company’s common stock, respectively, were not included in the computation of diluted earnings per share because their effects would have been anti-dilutive. Weighted average common shares outstanding, basic and dilutive, for all periods presented are presented on a post Stock Split basis.
