Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The Consolidated Financial Statements include the accounts of Eagle Bancorp, Inc. (the "Parent") and its subsidiaries (together with the Parent. the "Company"), with all significant intercompany transactions eliminated. EagleBank (the "Bank"), a Maryland chartered commercial bank, is the Company's principal subsidiary. The accounting and reporting policies of the Company conform to generally accepted accounting principles in the United States of America ("GAAP") and to general practices in the banking industry. The Consolidated Financial Statements and accompanying notes of the Company included herein are unaudited. The Consolidated Balance Sheet as of December 31, 2021 was derived from the audited Consolidated Balance Sheet as of that date. The Consolidated Financial Statements reflect all adjustments, consisting of normal recurring accruals that in the opinion of management, are necessary to present fairly the results for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In addition to the "Critical Accounting Policies" described below, the Company applies the accounting policies contained in Note 1 to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. Certain reclassifications have been made to 2021 amounts previously reported to conform to the 2022 presentation. Reclassifications had no effect on net income nor shareholders' equity. Nature of Operations The Company, through the Bank, conducts a full service community banking business, primarily in Northern Virginia, Suburban Maryland, and Washington, D.C. The primary financial services offered by the Bank include real estate, commercial and consumer lending, as well as traditional deposit and repurchase agreement products. The Bank is also active in the origination and sale of residential mortgage loans, the origination of small business loans, and the origination, securitization and sale of multifamily Federal Housing Administration ("FHA") loans. The guaranteed portion of small business loans, guaranteed by the Small Business Administration ("SBA"), is typically sold to third party investors in a transaction apart from the loan's origination. The Bank offers its products and services through seventeen banking offices, five lending centers and various digital capabilities, including remote deposit services and mobile banking services. Eagle Insurance Services, LLC, a subsidiary of the Bank, offers access to insurance products and services through a referral program with a third-party insurance broker. Landroval Municipal Finance, Inc., a subsidiary of the Bank, focuses on lending to municipalities by buying debt on the public market as well as direct purchase issuance. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates and such differences could be material to the consolidated financial statements. Investment Securities The Company recognizes acquired securities on the trade date. Investment securities comprise debt securities, which are classified depending on the Company's intent and ability to hold the securities to maturity. Debt securities are classified as available-for-sale when management may have the intent to sell them prior to maturity. Debt securities are classified as held-to-maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Premiums and discounts on investment securities held-to-maturity, like available-for-sale securities, are amortized or accreted to the earlier of call or maturity based on expected lives, which include prepayment adjustments and call optionality. The Company separately evaluates its investment securities held-to-maturity for any credit losses. The Company pools like securities and calculates expected credit losses through an estimate based on a security's credit rating, which is recognized as part of the allowance for credit losses for held-to-maturity securities and included in the balance of investment securities held-to-maturity on the Consolidated Balance Sheets. If the Company determines that a security indicates evidence of deteriorated credit quality, the security is individually-evaluated and a discounted cash flow analysis is performed and compared to the amortized cost basis of the security to estimate any credit losses. The Company excludes accrued interest receivable from the balance of amortized cost on its investment securities held-to-maturity as it would be written off in the event that an allowance for credit losses would be required. Transfers of Investment Securities from Available-for-Sale to Held-to-Maturity Transfers of debt securities into the held-to-maturity category from the available-for-sale category are made at amortized cost, net of unrealized gain or loss reported in accumulated other comprehensive income (loss) at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security. Loans Loans held for investment are stated at the principal amount outstanding, net of unamortized deferred costs and fees. Interest income on loans is recognized at the contractual rate on the principal amounts outstanding. Loan origination fees, net of direct loan origination costs, and commitment fees are deferred and amortized on the interest method over the term of the loan. Past due loans are placed on nonaccrual status when there is a clear indication that the borrower's cash flow may not be sufficient to meet payments as they become due. Generally, this conclusion is reached when a loan is 90 days past due. When a loan is placed on nonaccrual status, all previously accrued and unpaid interest is reversed through interest income. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement. Allowance for Credit Losses - Loans The allowance for credit losses - loans ("ACL") is an estimate of the expected credit losses in the loans held for investment portfolio. Accounting Standards Codification ("ASC") 326, "Financial Instruments-Credit Losses" requires that an estimate of current and expected credit losses ("CECL") be immediately recognized and reevaluated over the contractual life of the financial asset. The ACL is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the allowance when they are deemed uncollectible. Expected recoveries are recorded to the extent they do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Reserves on loans that do not share risk characteristics are evaluated on an individual basis (e.g., nonaccrual loans, TDRs). Nonaccrual loans are specifically reviewed for loss potential and when deemed appropriate are assigned a reserve based on an individual evaluation. The remainder of the portfolio, representing all loans not evaluated individually for impairment, is segregated by call report codes and a loan-level probability of default ("PD") / Loss Given Default ("LGD") cash flow method is applied using an exposure at default ("EAD") model. These historical loss rates are then modified to incorporate our reasonable and supportable forecast of future losses at the portfolio segment level, as well as any necessary qualitative adjustments. The Company uses regression analysis of historical internal and peer data (as Company loss data is insufficient) to determine suitable credit loss drivers to utilize when modeling lifetime PD and LGD. This analysis also determines how expected PD will be impacted by different forecasted levels of the loss drivers. A similar process is employed to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in reserve for unfunded commitments (“RUC”) on the Consolidated Balance Sheets. For periods beyond which we are able to develop reasonable and supportable forecasts, we revert to the historical loss rate on a straight-line basis over a twelve-month period. For each of these loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speeds, PD rates, and LGD rates. The modeling of expected prepayment speeds is based on historical internal data. EAD is based on each instrument's underlying amortization schedule in order to estimate the bank's expected credit loss exposure at the time of the borrower's potential default. For our cash flow model, management utilizes and forecasts regional unemployment by using a national forecast and estimating a regional adjustment based on historical differences between the two as the loss driver over our reasonable and supportable period of 18 months and reverts back to a historical loss rate over twelve months on a straight-line basis over the loan's remaining maturity. Unemployment projections materially inform our CECL economic forecast and resulted in a reduction to our ACL during the three months ended March 31, 2022. Management leverages economic projections from reputable and independent third parties to inform its loss driver forecasts over the forecast period. While our methodology in establishing the ACL attributes portions of the ACL and RUC to the separate loan pools or segments, the entire ACL and RUC is available to absorb credit losses expected in the total loan portfolio and total amount of unfunded credit commitments, respectively. Portfolio segments are used to pool loans with similar risk characteristics and align with our methodology for measuring expected credit losses. A summary of our primary portfolio segments is as follows: Commercial. The commercial loan portfolio comprises lines of credit and term loans for working capital, equipment, and other business assets across a variety of industries. These loans are used for general corporate purposes including financing working capital, internal growth, and acquisitions; and are generally secured by accounts receivable, inventory, equipment and other assets of our clients' businesses. Paycheck Protection Program ("PPP") . The PPP portfolio comprises loans issued under the SBA's Paycheck Protection Program to support small businesses impacted by the pandemic. PPP loans are approved subject to limited underwriting criteria following SBA guidelines, are unsecured, and are fully guaranteed as to principal and interest by the SBA. Income producing commercial real estate. Income producing commercial real estate loans comprise permanent and bridge financing provided to professional real estate owners/managers of commercial and residential real estate projects and properties who have a demonstrated record of past success with similar properties. Collateral properties include apartment buildings, office buildings, hotels, mixed-use buildings, retail, data centers, warehouse, and shopping centers. The primary source of repayment on these loans is generally expected to come from lease or operation of the real property collateral. Income producing commercial real estate loans are impacted by fluctuation in collateral values, as well as rental demand and rates. Owner occupied – commercial real estate. The owner occupied commercial real estate portfolio comprises permanent financing provided to operating companies and their related entities for the purchase or refinance of real property wherein their business operates. Collateral properties include industrial property, office buildings, religious facilities, mixed-use property, health care and educational facilities. Real estate mortgage – residential . Real estate mortgage residential loans comprise consumer mortgages for the purpose of purchasing or refinancing first lien real estate loans secured by primary-residence, second-home, and rental residential real property. Construction – commercial and residential. The construction commercial and residential loan portfolio comprises loans made to builders and developers of commercial and residential property, for both renovation, new construction, and development projects. Collateral properties include apartment buildings, mixed use property, residential condominiums, single and 1-4 residential property, and office buildings. The primary source of repayment on these loans is expected to come from the sale, permanent financing, or lease of the real property collateral. Construction loans are impacted by fluctuations in collateral values and the ability of the borrower or ultimate purchaser to obtain permanent financing. Construction – commercial and industrial ("C&I") (owner occupied) . The construction C&I (owner occupied) portfolio comprises loans to operating companies and their related entities for new construction or renovation of the real or leased property in which they operate. Generally these loans contain provisions for conversion to an owner occupied commercial real estate loan or to a commercial loan after completion of construction. Collateral properties include industrial, healthcare, religious facilities, restaurants, and office buildings. Home equity . The home equity portfolio comprises consumer lines of credit and loans secured by subordinate liens on residential real property. Other consumer. The other consumer portfolio comprises consumer purpose loans not secured by real property, including personal lines of credit and loans, overdraft lines, and vehicle loans. This category also includes other loan items such as overdrawn deposit accounts as well as loans and loan payments in process. We have several pass credit grades that are assigned to loans based on varying levels of risk, ranging from credits that are secured by cash or marketable securities, to watch credits which have all the characteristics of an acceptable credit risk but warrant more than the normal level of monitoring. Special mention loans are those that are currently protected by the sound worth and paying capacity of the borrower, but that are potentially weak and constitute an additional credit risk. These loans have the potential to deteriorate to a substandard grade due to the existence of financial or administrative deficiencies. Substandard loans have a well-defined weakness or weaknesses that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Some substandard loans are inadequately protected by the sound worth and paying capacity of the borrower and of the collateral pledged and may be considered impaired. Substandard loans can be accruing or can be on nonaccrual depending on the circumstances of the individual loans. Loans classified as doubtful have all the weaknesses inherent in substandard loans with the added characteristics that the weaknesses make collection in full highly questionable and improbable. The possibility of loss is extremely high. All doubtful loans are on nonaccrual. Classified loans represent the sum of loans graded substandard and doubtful. The methodology used in the estimation of the allowance, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality and forecasted economic conditions. Changes are reflected in the allowance on collectively assessed and individually assessed loans as the collectability of classified loans is evaluated with new information. As our portfolio has matured, historical loss ratios have been closely monitored. The review of the appropriateness of the allowance is performed by executive management and presented to management committees, Credit Oversight Committee (which replaced Directors Loan Committee), the Audit Committee, and the Board of Directors. The committees' reports to the Board are part of the Board review on a quarterly basis of our consolidated financial statements. When management determines that foreclosure is probable, and for certain collateral-dependent loans where foreclosure is not considered probable, expected credit losses are based on the estimated fair value of the collateral adjusted for selling costs, when appropriate. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless management has a reasonable expectation that a loan will be in a trouble debt restructuring. We do not measure an ACL on accrued interest receivable balances because these balances are written off in a timely manner as a reduction to interest income when loans are placed on nonaccrual status. Collateral Dependent Financial Assets Loans that do not share risk characteristics are evaluated on an individual basis. For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the net present value ("NPV") from the operation of the collateral. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. A loan that has been modified or renewed is considered a TDR when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. The Company's ACL reflects all effects of a TDR when an individual asset is specifically identified as a reasonably expected TDR. The Company has determined that a TDR is reasonably expected no later than the point when the lender concludes that modification is the best course of action and it is at least reasonably possible that the troubled borrower will accept some form of concession from the lender to avoid a default. Reasonably expected TDRs and executed non-performing TDRs are evaluated individually to determine the required ACL. Refer to the subsection above "Lendi ng operations and accommodations to borrowers" for a discussion on the impact of the CARES Act on TDRs. Allowance for Credit Losses - Available-for-Sale Debt Securities The Company utilizes ASC 326 to evaluate its available-for-sale ("AFS") debt security portfolio for expected credit losses. For AFS debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either criterion is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income, as a non-credit-related impairment. The entire amount of an impairment loss is recognized in earnings only when: (1) the Company intends to sell the security; or (2) it is more likely than not that the Company will have to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. In all other situations, only the portion of the impairment loss representing the credit loss must be recognized in earnings, with the remaining portion being recognized in shareholders' equity as comprehensive income, net of deferred taxes. Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit losses. Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Any impairment not recorded through an allowance for credit loss is recognized in other comprehensive income as a non-credit-related impairment. We have made a policy election to exclude accrued interest from the amortized cost basis of available-for-sale debt securities and report accrued interest separately in other assets in the Consolidated Balance Sheets. Available-for-sale debt securities are placed on nonaccrual status when we no longer expect to receive all contractual amounts due, which is generally at 90 days past due. Accrued interest receivable is reversed against interest income when a security is placed on nonaccrual status. Accordingly, we do not recognize an allowance for credit loss against accrued interest receivable. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial instruments include off-balance sheet credit instruments such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records a reserve for unfunded commitments ("RUC") on off-balance sheet credit exposures through a charge to provision for credit loss expense in the Company's Consolidated Statement of Income. The RUC on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur, and is included in the RUC on the Company's Consolidated Balance Sheet. The following table presents a breakdown of the provision for credit losses included in our Consolidated Statements of Income for the applicable periods (in thousands): Three Months Ended March 31, (dollars in thousands) 2022 2021 Provision for (reversal of) credit losses- loans $ (3,001) $ (2,261) Provision for (reversal of) credit losses- HTM debt securities 817 — Provision for (reversal of) credit losses- AFS debt securities (603) (89) Total $ (2,787) $ (2,350) These statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. Other New Authoritative Accounting Guidance Accounting Standards Adopted in 2022 : ASU No. 2020-06, " Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity " ("ASU 2020-06") simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument and more convertible preferred stock as a single equity instrument with no separate accounting for embedded conversion features. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. ASU 2020-06 also simplifies the diluted earnings per share (EPS) calculation in certain areas. In addition, the amendment updates the disclosure requirements for convertible instruments to increase the information transparency. For public business entities, excluding smaller reporting companies, the amendments in ASU 2020-06 are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. ASU 2020-06 did not have a material impact on the Company's consolidated financial statements. Accounting Standards Pending Adoption: ASU No. 2020-4, " Reference Rate Reform (Topic 848)" ("ASU 2020-4") provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/ costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-4 also provides numerous optional expedients for derivative accounting. ASU 2020-4 is effective March 12, 2020 through December 31, 2022. An entity may elect to apply ASU 2020-4 for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic within the Codification, the amendments in this ASU must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. We anticipate this ASU will simplify any modifications we execute between the selected start date (yet to be determined) and December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract resulting in writing off unamortized fees/costs. We do not anticipate that the LIBOR transition or the application of this ASU will have material effects on the Company's business operations and consolidated financial statements. ASU No. 2022-02, " Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures " ("ASU 2022-02") eliminates the accounting guidance for troubled debt restructurings ("TDRs") while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty that assess whether a modification has created a new loan. Additionally, ASU 2022-02 requires that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases. For entities that have adopted ASC 326, the amendments in the ASU are effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. The impact of ASU 2022-02 should be applied prospectively, or, for the recognition and measurement of TDRs, with a modified retrospective transition method. We are currently in the process of evaluating this guidance.

The Company reassessed classification of certain investments in the first quarter of 2022 and, effective March 31, 2022, it transferred a total of $1.1 billion of residential mortgage-backed securities, municipal bonds and corporate bonds from available-for-sale to held-to-maturity securities, including $237.0 million of securities acquired in the first quarter of 2022 for which its intention to hold to maturity was finalized. At the time of transfer, the Company reversed the allowance for credit losses associated with the available-for-sale securities through provision for credit losses. The securities were transferred at their amortized cost basis, net of any remaining unrealized gain or loss reported in accumulated other comprehensive income. The related unrealized loss totaling $66.2 million included in other comprehensive loss remained in other comprehensive loss, to be amortized out of other comprehensive loss with an offsetting entry to interest income as a yield adjustment through earnings over the remaining term of the securities. No gain or loss was recorded at the time of transfer. Subsequent to transfer, the allowance for credit losses on these securities was evaluated under the accounting policy for held-to-maturity securities. Accrued interest receivable on available-for-sale securities totaled $4.5 million and $6.0 million at March 31, 2022 and December 31, 2021, respectively, and accrued interest receivable on held-to-maturity securities totaled $4.1 million at March 31, 2022. The accrued interest on investment securities is excluded from the amortized cost of the securities and is reported in other assets in the Consolidated Balance Sheets. Gross unrealized losses and fair value of available-for-sale securities, by length of time that individual securities have been in a continuous unrealized loss position are as follows: Less Than 12 Months 12 Months or Greater Total Estimated Estimated Estimated Number of Fair Unrealized Fair Unrealized Fair Unrealized (dollars in thousands) Securities Value Losses Value Losses Value Losses March 31, 2022 U.S. treasury bonds 2 $ 47,492 $ 2,225 $ — $ — $ 47,492 $ 2,225 U.

However, as of March 31, 2022, the Company determined that certain of the unrealized loss positions in available-for-sale & held-to-maturity corporate and municipal bonds were evidence of expected credit losses, and therefore, an allowance for credit losses of $18 thousand was recorded for AFS securities and $817 thousand for HTM securities. The weighted average duration of debt securities, which comprise 100.0% of total investment securitie s, is 4.9 years. If quoted prices are not available, fair value is measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. The Company does not intend to sell the investments and it is more likely than not that the Company will not have to sell the securities before recovery of its amortized cost basis, which may be at maturity. The amortized cost and estimated fair value of available-for-sale and held-to-maturity securities at March 31, 2022 and December 31, 2021 by contractual maturity are shown in the table below. Contractual maturities for residential mortgage-backed securities ("MBS") are excluded as they may differ significantly from expected maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

For the three months ended March 31, 2022, net realized losses on sales of investments securities were $25 thousand on sales of investment securities. For the three months ended March 31, 2021, net realized gains on sales of investments securities were $221 thousand. The Company received proceeds of $6.2 million and $28.5 million for the three months ended March 31, 2022 and 2021, respectively, on sales and calls of securities. The carrying value of securities pledged as collateral for certain government deposits, securities sold under agreements to repurchase, and certain lines of credit with correspondent banks at March 31, 2022 and December 31, 2021 was $251.0 million and $261.0 million, respectively, which were well in excess of required amounts in order to operationally provide significant reserve amounts for new business. As of March 31, 2022 and December 31, 2021, there were no holdings of securities of any one issuer, other than the U.S. Government and U.S. agency securities, which exceeded ten percent of shareholders' equity.

Loans and Allowance for Credit

Loans and Allowance for Credit Losses	3 Months Ended

Receivables [Abstract]
Loans and Allowance for Credit Losses	Loans and Allowance for Credit Losses The Bank makes loans to customers primarily in the Washington, D.C. metropolitan area and surrounding communities. A substantial portion of the Bank's loan portfolio consists of loans to businesses secured by real estate and other business assets. Loans, net of unamortized net deferred fees, at March 31, 2022 and December 31, 2021 are summarized by type as follows: March 31, 2022 December 31, 2021 (dollars in thousands, except amounts in the footnote) Amount % Amount % Commercial $ 1,377,615 19 % $ 1,354,317 19 % PPP loans 35,744 1 % 51,105 1 % Income-producing - commercial real estate 3,543,795 50 % 3,385,298 48 % Owner-occupied - commercial real estate 1,104,982 15 % 1,087,776 15 % Real estate mortgage - residential 72,238 1 % 73,966 1 % Construction - commercial and residential 783,101 11 % 896,319 13 % Construction - C&I (owner-occupied) 140,282 2 % 159,579 2 % Home equity 54,804 1 % 55,811 1 % Other consumer 1,246 — 1,427 — Total loans 7,113,807 100 % 7,065,598 100 % Less: allowance for credit losses (71,505) (74,965) Net loans (1) $ 7,042,302 $ 6,990,633 (1) Excludes accrued interest receivable of $36.9 million and $38.6 million at March 31, 2022 and December 31, 2021, respectively, which were recorded in other assets on the Consolidated Balance Sheets. Unamortized net deferred fees amounted to $23.7 million and $26.9 million at March 31, 2022 and December 31, 2021, respectively. As of March 31, 2022 and December 31, 2021, the Bank serviced $339.5 million and $351.1 million , respectively, of multifamily FHA loans, SBA loans and other loan participations that are not reflected as loan balances on the Consolidated Balance Sheets. Real estate loans are secured primarily by duly recorded first deeds of trust or mortgages. In some cases, the Bank may accept a recorded junior trust position. In general, borrowers will have a proven ability to build, lease, manage and/or sell a commercial or residential project and demonstrate satisfactory financial condition. Additionally, an equity contribution toward the project is customarily required. Construction loans require that the financial condition and experience of the general contractor and major subcontractors be satisfactory to the Bank. Guaranteed, fixed price contracts are required whenever appropriate, along with payment and performance bonds or completion bonds for larger scale projects. Loans intended for residential land acquisition, lot development and construction are made on the premise that the land: 1) is or will be developed for building sites for residential structures, and 2) will ultimately be utilized for construction or improvement of residential zoned real properties, including the creation of housing. Residential development and construction loans will finance projects such as single family subdivisions, planned unit developments, townhouses, and condominiums. Residential land acquisition, development and construction loans generally are underwritten with a maximum term of 36 months, including extensions approved at origination. Commercial land acquisition and construction loans are secured by real property where loan funds will be used to acquire land and to construct or improve appropriately zoned real property for the creation of income producing or owner user commercial properties. Borrowers are generally required to put equity into each project at levels determined by the appropriate approval authority. Commercial land acquisition and construction loans generally are underwritten with a maximum term of 24 months. Substantially all construction draw requests must be presented in writing on American Institute of Architects documents and certified either by the contractor, the borrower and/or the borrower's architect. Each draw request shall also include the borrower's soft cost breakdown certified by the borrower or their Chief Financial Officer. Prior to an advance, the Bank or its contractor inspects the project to determine that the work has been completed, to justify the draw requisition. Commercial permanent loans are generally secured by improved real property which is generating income in the normal course of operation. Debt service coverage, assuming stabilized occupancy, must be satisfactory to support a permanent loan. The debt service coverage ratio is ordinarily at least 1.15 to 1.0. As part of the underwriting process, debt service coverage ratios are stress tested assuming a 200 basis point increase in interest rates from their current levels. Commercial permanent loans generally are underwritten with a term not greater than 10 years or the remaining useful life of the property, whichever is lower. The preferred term is between 5 to 7 years, with amortization to a maximum of 25 years. The Company's loan portfolio includes acquisition, development and construction ("ADC") real estate loans including both investment and owner occupied projects. ADC loans amounted to $1.5 billion at March 31, 2022. A portion of the ADC portfolio, both speculative and non-speculative, includes loan-funded interest reserves at origination. ADC loans that provide for the use of interest reserves represent approximately 57.2% of the outstanding ADC loan portfolio at March 31, 2022. The decision to establish a loan-funded interest reserve is made upon origination of the ADC loan and is based upon a number of factors considered during underwriting of the credit including: (1) the feasibility of the project; (2) the experience of the sponsor; (3) the creditworthiness of the borrower and guarantors; (4) the borrower equity contribution; and (5) the level of collateral protection. When appropriate, an interest reserve provides an effective means of addressing the cash flow characteristics of a properly underwritten ADC loan. The Company recognizes that one of the risks inherent in the use of interest reserves is the potential masking of underlying problems with the project and/or the borrower's ability to repay the loan. In order to mitigate these inherent risks, the Company employs a series of reporting and monitoring mechanisms on all ADC loans, whether or not an interest reserve is provided, including: (1) construction and development timelines which are monitored on an ongoing basis which track the progress of a given project to the timeline projected at origination; (2) a construction loan administration department independent of the lending function; (3) third party independent construction loan inspection reports; (4) monthly interest reserve monitoring reports detailing the balance of the interest reserves approved at origination and the days of interest carry represented by the reserve balances as compared to the then current anticipated time to completion and/or sale of speculative projects; and (5) quarterly commercial real estate construction meetings among senior Company management, which includes monitoring of current and projected real estate market conditions. If a project has performed as expected, it is the customary practice of the Company to increase loan-funded interest reserves. The following tables detail activity in the allowance for credit losses by portfolio segment for the three months ended March 31, 2022 and 2021. PPP loans are excluded from these tables since they do not carry an allowance for credit loss, as these loans are fully guaranteed as to principal and interest by the SBA, whose guarantee is backed by the full faith and credit of the U.S. Government. Allocation of a portion of the allowance to one category of loans does not restrict the use of the allowance to absorb losses in other categories.

The Company's primary credit quality indicators inform an internal credit risk rating system that categorizes loans into pass, watch, special mention, or classified categories. Credit risk ratings are applied individually to those classes of loans that have significant or unique credit characteristics that benefit from a case-by-case evaluation. These are typically loans to businesses or individuals in the classes which comprise the commercial portfolio segment. Groups of loans that are underwritten and structured using standardized criteria and characteristics, such as statistical models (e.g., credit scoring or payment performance), are typically risk rated and monitored collectively. These are typically loans to individuals in the classes which comprise the consumer portfolio segment. The following are the definitions of the Company's credit quality indicators: Pass: Loans in all classes that comprise the commercial and consumer portfolio segments that are not adversely rated, are contractually current as to principal and interest, and are otherwise in compliance with the contractual terms of the loan agreement. Management believes that there is a low likelihood of loss related to those loans that are considered pass. Watch: Loan paying as agreed with generally acceptable asset quality; however the obligor's performance has not met expectations. Balance sheet and/or income statement has shown deterioration to the point that the obligor could not sustain any further setbacks. Credit is expected to be strengthened through improved obligor performance and/or additional collateral within a reasonable period of time. Special Mention: Loans in the classes that comprise the commercial portfolio segment that have potential weaknesses that deserve management's close attention. If not addressed, these potential weaknesses may result in deterioration of the repayment prospects for the loan. The special mention credit quality indicator is not used for classes of loans that comprise the consumer portfolio segment. Management believes that there is a moderate likelihood of some loss related to those loans that are considered special mention. Classified: Classified (a) Substandard – Loans inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard loans, does not have to exist in individual loans classified substandard. Classified (b) Doubtful – Loans that have all the weaknesses inherent in a loan classified substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work to the advantage and strengthening of the assets, its classification as an estimated loss is deferred until its more exact status may be determined. The Company's credit quality indicators are generally updated annually, and; however , credits rated watch or below are reviewed more frequently. Based on the most recent analysis performed, amortized cost basis of loans by risk category, class and year of origination are as follows: March 31, 2022 (dollars in thousands) Prior 2018 2019 2020 2021 2022 Revolving Loans Amort.

The committees make a thorough assessment of the conditions and circumstances surrounding each delinquent loan. The Bank's loan policy requires that loans be placed on nonaccrual if they are 90 days past-due, unless they are well secured and in the process of collection. Additionally, Credit Administration specifically analyzes the status of development and construction projects, sales activities and utilization of interest reserves in order to carefully and prudently assess potential increased levels of risk requiring additional reserves.

These loans are intended to guarantee payroll and other costs to help those businesses remain viable and allow their workers to pay their bills. (2) Excludes TDRs that were performing under their restructured terms totaling $10.1 million and $10.2 million at March 31, 2022 and December 31, 2021, respectively. (3) Gross interest income of $325 thousand and approximately $800 thousand would have been recorded for the three months ended March 31, 2022 and 2021, respectively, if nonaccrual loans shown above had been current and in accordance with their original terms, while no interest income was actually recorded on such loans for the three months ended March 31, 2022 and 2021 respectively. See Note 1 to the Consolidated Financial Statements for a description of the Company's policy for placing loans on nonaccrual status. Modifications A modification of a loan constitutes a TDR when the borrower is experiencing financial difficulty and the modification constitutes a concession. The Company offers various types of concessions when modifying a loan. Commercial and industrial loans modified in a TDR often involve temporary interest-only payments, term extensions, and converting revolving credit lines to term loans. Additional collateral, a co-borrower, or a guarantor is often requested. Commercial mortgage and construction loans modified in a TDR often involve reducing the interest rate for the remaining term of the loan, extending the maturity date at an interest rate lower than the current market rate for new debt with similar risk, or substituting or adding a new borrower or guarantor. Construction loans modified in a TDR may also involve extending the interest-only payment period. As of March 31, 2022 and December 31, 2021, all performing TDRs were categorized as interest-only modifications . Loans modified in a TDR for the Company may have the financial effect of increasing the specific allowance associated with the loan. An allowance for consumer and commercial loans that have been modified in a TDR is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's observable market price, or the estimated fair value of the collateral, less any selling costs, if the loan is collateral dependent. Management exercises significant judgment in developing these estimates. In response to the COVID-19 pandemic and its economic impact to our customers, we implemented a short-term modification program that complied with the CARES Act and ASC 310-40 to provide temporary payment relief to those borrowers directly impacted by COVID-19 who were not more than 30 days past due as of December 31, 2019. This program allowed for a deferral of payments for 90 days, which we extended for an additional 90 days for certain borrowers, for a maximum of 180 days on a cumulative and successive basis. The deferred payments along with interest accrued during the deferral period are due and payable on the maturity date. Additionally, none of the deferrals are reflected in the Company's asset quality measures (i.e. non-performing loans) due to the provision of the CARES Act that permits U.S. financial institutions to temporarily suspend the GAAP requirements to treat such short-term loan modifications as TDR. Similar provisions have also been confirmed by interagency guidance issued by the federal banking agencies and confirmed with staff members of the Financial Accounting Standards Board. As of March 31, 2022, substantially all of the borrowers granted deferrals under this program have returned to regular payment status. The following table presents by class, the recorded investment of loans modified in TDRs held by the Company for the three months ended March 31, 2022 and 2021.

Five of these loans totaling approximately $10.1 million were performing under their modified terms as of March 31, 2022. For the first three months of 2022 there were two performing TDR loans that defaulted on their modified terms. For the first three months of 2021, one performing TDR loan, with a balance of $101 thousand, defaulted on its modified terms and was placed on nonaccrual status. For the three months ended March 31, 2021, one previously nonperforming restructured loan had its collateral sold and all principal collected along with partial collection of delinquent interest; in addition, one restructured loan purchased as part of the 2014 acquisition of Virginia Heritage Bank has now had its full carrying value collected, while additional payments will recover previously written off principal and interest, and zero nonperforming restructured loan was charged off. No similar transactions occurred during the three months ended March 31, 2022. Commercial and consumer loans modified in a TDR are closely monitored for delinquency as an early indicator of possible future default. If loans modified in a TDR subsequently default, the Company evaluates the loan for possible further loss. The allowance may be increased, adjustments may be made in the allocation of the allowance, or partial charge-offs may be taken to further write-down the carrying value of the loan.

Leases [Abstract]
Leases	Leases The Company accounts for leases in accordance with ASC Topic 842. A lease is defined as a contract that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. Substantially all of the leases in which the Company is the lessee comprise real estate property for branch offices, ATM locations, and corporate office space. Substantially all of our leases are classified as operating leases. With the adoption of ASC Topic 842, operating lease agreements were required to be recognized on the Consolidated Balance Sheets as a right-of-use ("ROU") asset and a corresponding lease liability. As of March 31, 2022 and December 31, 2021, the Company had $29.0 million and $30.6 million of operating lease ROU assets, respectively, and $33.9 million and $35.5 million of operating lease liabilities, respectively, on the Company's Consolidated Balance Sheets. The Company elects not to recognize ROU assets and lease liabilities arising from short-term leases, leases with initial terms of twelve months or less, or equipment leases (deemed immaterial) on the Consolidated Balance Sheets. The leases contain terms and conditions of options to extend or terminate the lease which are recognized as part of the ROU assets and lease liabilities when an economic benefit to exercise the option exists and there is a 90% probability that the Company will exercise the option. If these criteria are not met, the options are not included in ROU assets and lease liabilities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Other Derivatives	Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Mortgage Banking Derivatives As part of its mortgage banking activities, the Bank enters into interest rate lock commitments, which are commitments to originate loans where the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The Bank then locks in the loan and interest rate with an investor and commits to deliver the loan if settlement occurs ("best efforts") or commits to deliver the locked loan in a binding ("mandatory") delivery program with an investor. Certain loans under interest rate lock commitments are covered under forward sales contracts of MBS. Forward sales contracts of MBS are recorded at fair value with changes in fair value recorded in noninterest income. Interest rate lock commitments and commitments to deliver loans to investors are considered derivatives. The market value of interest rate lock commitments and best efforts contracts are not readily ascertainable with precision because they are not actively traded in stand-alone markets. The Bank determines the fair value of interest rate lock commitments and delivery contracts by measuring the fair value of the underlying asset, which is impacted by current interest rates, taking into consideration the probability that the interest rate lock commitments will close or will be funded. Certain additional risks arise from these forward delivery contracts in that the counterparties to the contracts may not be able to meet the terms of the contracts. The Bank does not expect any counterparty to any MBS to fail to meet its obligation. Additional risks inherent in mandatory delivery programs include the risk that, if the Bank does not close the loans subject to interest rate risk lock commitments, it will still be obligated to deliver MBS to the counterparty under the forward sales agreement. Should this be required, the Bank could incur significant costs in acquiring replacement loans or MBS and such costs could have an adverse effect on mortgage banking operations. The fair value of the mortgage banking derivatives is recorded as a freestanding asset or liability with the change in value being recognized in current earnings during the period of change. The gain on sale of loans for the three months ended March 31, 2022 included a $266 thousand net loss relating to mortgage banking derivative instruments. No net loss was recorded for the three months ended March 31, 2021. Cash Flow Hedges of Interest Rate Risk The Company uses interest rate swap agreements to assist in its interest rate risk management. The Company's objective in using interest rate derivatives designated as cash flow hedges under ASC 815 is to add stability to interest expense and to better manage its exposure to interest rate movements. To accomplish this objective, the Company utilizes interest rate swaps as part of its interest rate risk management strategy intended to mitigate the potential risk of rising interest rates on the Bank's cost of funds. The notional amounts of the interest rate swaps designated as cash flow hedges do not represent amounts exchanged by the counterparties, but rather, the notional amount is used to determine, along with other terms of the derivative, the amounts to be exchanged between the counterparties. The interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from one counterparty in exchange for the Company making fixed payments. The Company's intent is to hedge its exposure to the variability in potential future interest rate conditions on existing financial instruments. The Company's derivative position is classified within Level 2 of the fair value hierarchy and is valued using models generally accepted in the financial services industry and that use actively quoted or observable market input values from external market data providers and/or non-binding broker-dealer quotations. The fair value of the derivatives is determined using discounted cash flow models. These models' key assumptions include the contractual terms of the respective contract along with significant observable inputs, including interest rates, yield curves, nonperformance risk and volatility. See Note 10. Fair Value Measurements. For derivatives designated as cash flow hedges, changes in the fair value of the derivative are initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The Company's sole designated cash flow hedge matured during April 2021. Thus, as of March 31, 2022 and December 31, 2021, the Company had no designated cash flow hedge interest rate swap transactions outstanding associated with the Company's variable rate deposits. Amounts reported in accumulated other comprehensive income related to designated cash flow hedge derivatives were reclassified to interest income/expense as interest payments were made/received on the Company's variable-rate assets/liabilities. Non-designated Hedges Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate caps and swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. The Company entered into credit risk participation agreements ("RPAs") with institutional counterparties, under which the Company assumes its pro-rata share of the credit exposure associated with a borrower's performance related to interest rate derivative contracts. The fair value of RPAs is calculated by determining the total expected asset or liability exposure of the derivatives to the borrowers and applying the borrowers' credit spread to that exposure. Total expected exposure incorporates both the current and potential future exposure of the derivatives, derived from using observable inputs, such as yield curves and volatilities. Credit-risk-related Contingent Features The Company has agreements with each of its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness, then the Company could also be declared in default on its derivative obligations. The Company is exposed to credit risk in the event of nonperformance by the interest rate derivative counterparty. The Company minimizes this risk by entering into derivative contracts with only large, stable financial institutions, and the Company has not experienced, and does not expect, any losses from counterparty nonperformance on the interest rate derivatives. The Company monitors counterparty risk in accordance with the provisions of ASC Topic 815, "Derivatives and Hedging." In addition, the interest rate derivative agreements contain language outlining collateral-pledging requirements for each counterparty. The interest rate derivative agreements detail: 1) that collateral be posted when the market value exceeds certain threshold limits associated with the secured party's exposure; 2) if the Company defaults on any of its indebtedness (including default where repayment of the indebtedness has not been accelerated by the lender), then the Company could also be declared in default on its derivative obligations; 3) if the Company fails to maintain its status as a well-capitalized institution then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. The table below identifies the balance sheet category and fair value of the Company's designated cash flow hedge derivative instruments and non-designated hedges as of March 31, 2022 and December 31, 2021. The Company has a minimum collateral posting threshold with its derivative counterparty. If the Company had breached any provisions under the agreement at March 31, 2022, it could have been required to settle its obligations under the agreement at the termination value.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820, "Fair Value Measurements and Disclosures," establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1 Quoted prices in active exchange markets for identical assets or liabilities; also includes certain U.S. Treasury and other U.S. Government and agency securities actively traded in over-the-counter markets. Level 2 Observable inputs other than Level 1 including quoted prices for similar assets or liabilities, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data; also includes derivative contracts whose value is determined using a pricing model with observable market inputs or can be derived principally from or corroborated by observable market data. This category generally includes certain U.S. Government and agency securities, corporate debt securities, derivative instruments, and residential mortgage loans held for sale. Level 3 Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs for single dealer nonbinding quotes not corroborated by observable market data. This category generally includes certain private equity investments, retained interests from securitizations, and certain collateralized debt obligations. Assets and Liabilities Recorded at Fair Value on a Recurring Basis The tables below present the recorded amount of assets and liabilities measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021. Significant Significant Other Other Observable Unobservable Quoted Prices Inputs Inputs Total (dollars in thousands) (Level 1) (Level 2) (Level 3) (Fair Value) March 31, 2022 Assets: Investment securities available-for-sale: U.S treasury bonds $ — $ 47,492 $ — $ 47,492 U.

Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair value is measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange such as the New York Stock Exchange. Level 2 securities include U.S. agency debt securities, mortgage-backed securities issued by Government Sponsored Entities and municipal bonds. Securities classified as Level 3 include securities in less liquid markets, the carrying amounts approximate the fair value. Loans held for sale : The Company has elected to carry loans held for sale at fair value. This election reduces certain timing differences in the Consolidated Statement of Income and better aligns with the management of the portfolio from a business perspective. Fair value is derived from secondary market quotations for similar instruments. Gains and losses on sales of residential mortgage loans are recorded as a component of noninterest income in the Consolidated Statements of Income. Gains and losses on sales of multifamily FHA securities are recorded as a component of noninterest income in the Consolidated Statements of Income. As such, the Company classifies loans subjected to fair value adjustments as Level 2 valuation. The following tables summarize the difference between the aggregate fair value and the aggregate unpaid principal balance for loans held for sale measured at fair value as of March 31, 2022 and December 31, 2021. Aggregate Unpaid (dollars in thousands) Fair Value Principal Balance Difference March 31, 2022 Loans held for sale $ 25,504 $ 25,304 $ 200 December 31, 2021 Loans held for sale $ 47,218 $ 46,623 $ 595 There were no residential mortgage loans held for sale that were 90 or more days past due or on nonaccrual status as of March 31, 2022 or December 31, 2021. Credit risk participation agreements : The Company enters into credit risk participation agreements ("RPAs") with institutional counterparties, under which the Company assumes its pro-rata share of the credit exposure associated with a borrower's performance related to interest rate derivative contracts. The fair value of RPAs is calculated by determining the total expected asset or liability exposure of the derivatives to the borrowers and applying the borrowers' credit spread to that exposure. Total expected exposure incorporates both the current and potential future exposure of the derivatives, derived from using observable inputs, such as yield curves and volatilities. Accordingly, RPAs fall within Level 2. Interest rate caps: The Company entered into an interest rate cap agreement ("cap") with an institutional counterparty, under which the Company will receive cash if and when market rates exceed the cap's strike rate. The fair value of the cap is calculated by determining the total expected asset or liability exposure of the derivatives. Total expected exposure incorporates both the current and potential future exposure of the derivative, derived from using observable inputs, such as yield curves and volatilities. Accordingly, the cap falls within Level 2. Mortgage banking derivatives for loans settled on a mandatory basis: The Company relied on a third-party pricing service to value its mortgage banking derivative financial assets and liabilities, which the Company classifies as a Level 3 valuation. The external valuation model to estimate the fair value of its interest rate lock commitments to originate residential mortgage loans held for sale includes grouping the interest rate lock commitments by interest rate and terms, applying an estimated pull-through rate based on historical experience, and then multiplying by quoted investor prices determined to be reasonably applicable to the loan commitment groups based on interest rate, terms, and rate lock expiration dates of the loan commitment groups. The Company also relies on an external valuation model to estimate the fair value of its forward commitments to sell residential mortgage loans (i.e. an estimate of what the Company would receive or pay to terminate the forward delivery contract based on market prices for similar financial instruments), which includes matching specific terms and maturities of the forward commitments against applicable investor pricing. Mortgage banking derivative for loans settled best efforts basis : The significant unobservable input (Level 3) used in the fair value measurement of the Company's interest rate lock commitments is the pull through ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. An increase in the pull through ratio (i.e. higher percentage of loans are estimated to close) will increase the gain or loss. The pull through ratio is largely dependent on the loan processing stage that a loan is currently in. The pull through rate is computed by the Company's secondary marketing consultant using historical data and the ratio is periodically reviewed by the Company for reasonableness. The following is a reconciliation of activity for assets measured at fair value based on Significant Other Unobservable Inputs (Level 3): Investment Securities Mortgage Banking (dollars in thousands) Available-for-Sale Derivatives Total Assets: Beginning balance at January 1, 2022 $ 12,000 $ 636 $ 12,636 Realized gain (loss) included in earnings — (427) (427) Transferred from available-for-sale to held-to-maturity (12,000) — (12,000) Ending balance at March 31, 2022 $ — $ 209 $ 209 Investment Securities Mortgage Banking (dollars in thousands) Available-for-Sale Derivatives Total Assets: Beginning balance at January 1, 2021 $ 1,500 $ 5,213 $ 6,713 Realized loss included in earnings — (4,577) (4,577) Reclass Level 2 to Level 3 12,000 — 12,000 Principal redemption (1,500) — (1,500) Ending balance at December 31, 2021 $ 12,000 $ 636 $ 12,636 The investment securities available-for-sale classified as Level 3 consist of one corporate bond of a local banking company which is not publicly traded, and for which the carrying amount approximates fair value. For Level 3 assets measured at fair value on a recurring or nonrecurring basis as of March 31, 2022 and December 31, 2021, the significant unobservable inputs used in the fair value measurements were as follows: March 31, 2022 December 31, 2021 (dollars in thousands) Valuation Technique Description Range Weighted Average (1) Fair Value Weighted Average (1) Fair Value Mortgage banking derivatives Pricing Model Pull Through Rate 80.7% - 85.3% 82.90 % $ 209 86.40 % $ 636 (1) Unobservable inputs for mortgage banking derivatives were weighted by loan amount. Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis The Company measures certain assets at fair value on a nonrecurring basis and the following is a general description of the methods used to value such assets. At March 31, 2022, substantially all of the Company's individually evaluated loans were evaluated based upon the fair value of the collateral. In accordance with ASC Topic 820, individually evaluated loans where an allowance is established based on the fair value of collateral, i.e. those that are collateral dependent, require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value, the Company records the loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the Company records the loan as nonrecurring Level 3.

Commitments and Contingencies Disclosure [Abstract]
Legal Contingencies	Legal Contingencies There have been no material changes in the status of the legal proceedings previously disclosed in Part II, Item 8, "Note 21 - Commitments and Contingent Liabilities" of the Company's Annual Report on Form 10-K for the year ended December 31, 2021, except as follows. From time to time, the Company and its subsidiaries are involved in various legal proceedings incidental to their business in the ordinary course, including matters in which damages in various amounts are claimed. Based on information currently available, the Company does not believe that the liabilities (if any) resulting from such legal proceedings will have a material effect on the financial position of the Company. However, in light of the inherent uncertainties involved in such matters, ongoing legal expenses or an adverse outcome in one or more of these matters could materially and adversely affect the Company's financial condition, results of operations or cash flows in any particular reporting period, as well as its reputation. As previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2021, on February 10, 2022, the United States District Court for the Southern District of New York (the "SDNY") approved the settlement agreement of a putative class action lawsuit filed against the Company, its current and former President and Chief Executive Officer and its current and former Chief Financial Officer. The settlement included a total payment by the Company of $7.5 million in exchange for the release of all of the defendants from all alleged claims in the class action suit, without any admission or concession of wrongdoing by the Company or the other defendants. In connection with the previously disclosed investigation by the SEC, the Company's discussions with the Staff have progressed, and the Company continues to engage with the Staff, including senior Staff members, about a potential resolution or settlement of the Staff's investigation with respect to the Company. The Company is hopeful that these discussions will lead to a timely resolution of the investigation as it relates to the Company and any current employees and directors on a mutually agreeable basis, but there can be no assurance that will be the case. There also can be no assurance that this would result in resolution of any charges against former employees or directors, given the Staff's ongoing review of the factual record. Any agreements reached by the Company with the Staff would be subject to approval by the Commission, and there can be no assurance that it would be approved. We are unable to predict the outcome of the investigation or these discussions or whether any potential resolution would have a material impact on the Company. The Company is also continuing discussions with the Staff of the Federal Reserve Board about a potential resolution or settlement of its investigation with respect to the Company. With respect to the other investigations described above, we are unable to predict their duration, scope or outcome.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The Consolidated Financial Statements include the accounts of Eagle Bancorp, Inc. (the "Parent") and its subsidiaries (together with the Parent. the "Company"), with all significant intercompany transactions eliminated. EagleBank (the "Bank"), a Maryland chartered commercial bank, is the Company's principal subsidiary. The accounting and reporting policies of the Company conform to generally accepted accounting principles in the United States of America ("GAAP") and to general practices in the banking industry. The Consolidated Financial Statements and accompanying notes of the Company included herein are unaudited. The Consolidated Balance Sheet as of December 31, 2021 was derived from the audited Consolidated Balance Sheet as of that date. The Consolidated Financial Statements reflect all adjustments, consisting of normal recurring accruals that in the opinion of management, are necessary to present fairly the results for the periods presented. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). In addition to the "Critical Accounting Policies" described below, the Company applies the accounting policies contained in Note 1 to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. Certain reclassifications have been made to 2021 amounts previously reported to conform to the 2022 presentation. Reclassifications had no effect on net income nor shareholders' equity.
Nature of Operations	Nature of Operations The Company, through the Bank, conducts a full service community banking business, primarily in Northern Virginia, Suburban Maryland, and Washington, D.C. The primary financial services offered by the Bank include real estate, commercial and consumer lending, as well as traditional deposit and repurchase agreement products. The Bank is also active in the origination and sale of residential mortgage loans, the origination of small business loans, and the origination, securitization and sale of multifamily Federal Housing Administration ("FHA") loans. The guaranteed portion of small business loans, guaranteed by the Small Business Administration ("SBA"), is typically sold to third party investors in a transaction apart from the loan's origination. The Bank offers its products and services through seventeen banking offices, five lending centers and various digital capabilities, including remote deposit services and mobile banking services. Eagle Insurance Services, LLC, a subsidiary of the Bank, offers access to insurance products and services through a referral program with a third-party insurance broker. Landroval Municipal Finance, Inc., a subsidiary of the Bank, focuses on lending to municipalities by buying debt on the public market as well as direct purchase issuance.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates and such differences could be material to the consolidated financial statements.
Investment Securities	Investment Securities The Company recognizes acquired securities on the trade date. Investment securities comprise debt securities, which are classified depending on the Company's intent and ability to hold the securities to maturity. Debt securities are classified as available-for-sale when management may have the intent to sell them prior to maturity. Debt securities are classified as held-to-maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Premiums and discounts on investment securities held-to-maturity, like available-for-sale securities, are amortized or accreted to the earlier of call or maturity based on expected lives, which include prepayment adjustments and call optionality. The Company separately evaluates its investment securities held-to-maturity for any credit losses. The Company pools like securities and calculates expected credit losses through an estimate based on a security's credit rating, which is recognized as part of the allowance for credit losses for held-to-maturity securities and included in the balance of investment securities held-to-maturity on the Consolidated Balance Sheets. If the Company determines that a security indicates evidence of deteriorated credit quality, the security is individually-evaluated and a discounted cash flow analysis is performed and compared to the amortized cost basis of the security to estimate any credit losses. The Company excludes accrued interest receivable from the balance of amortized cost on its investment securities held-to-maturity as it would be written off in the event that an allowance for credit losses would be required. Transfers of Investment Securities from Available-for-Sale to Held-to-Maturity Transfers of debt securities into the held-to-maturity category from the available-for-sale category are made at amortized cost, net of unrealized gain or loss reported in accumulated other comprehensive income (loss) at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in other comprehensive income and in the carrying value of the held-to-maturity securities. Such amounts are amortized over the remaining life of the security.
Loans	Loans Loans held for investment are stated at the principal amount outstanding, net of unamortized deferred costs and fees. Interest income on loans is recognized at the contractual rate on the principal amounts outstanding. Loan origination fees, net of direct loan origination costs, and commitment fees are deferred and amortized on the interest method over the term of the loan. Past due loans are placed on nonaccrual status when there is a clear indication that the borrower's cash flow may not be sufficient to meet payments as they become due. Generally, this conclusion is reached when a loan is 90 days past due. When a loan is placed on nonaccrual status, all previously accrued and unpaid interest is reversed through interest income. Interest income is subsequently recognized on a cash basis as long as the remaining book balance of the asset is deemed to be collectible. If collectability is questionable, then cash payments are applied to principal. A loan is placed back on accrual status when both principal and interest are current and it is probable that we will be able to collect all amounts due (both principal and interest) according to the terms of the loan agreement.
Allowance for Credit Losses- Loans	Allowance for Credit Losses - Loans The allowance for credit losses - loans ("ACL") is an estimate of the expected credit losses in the loans held for investment portfolio. Accounting Standards Codification ("ASC") 326, "Financial Instruments-Credit Losses" requires that an estimate of current and expected credit losses ("CECL") be immediately recognized and reevaluated over the contractual life of the financial asset. The ACL is a valuation account that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the allowance when they are deemed uncollectible. Expected recoveries are recorded to the extent they do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Reserves on loans that do not share risk characteristics are evaluated on an individual basis (e.g., nonaccrual loans, TDRs). Nonaccrual loans are specifically reviewed for loss potential and when deemed appropriate are assigned a reserve based on an individual evaluation. The remainder of the portfolio, representing all loans not evaluated individually for impairment, is segregated by call report codes and a loan-level probability of default ("PD") / Loss Given Default ("LGD") cash flow method is applied using an exposure at default ("EAD") model. These historical loss rates are then modified to incorporate our reasonable and supportable forecast of future losses at the portfolio segment level, as well as any necessary qualitative adjustments. The Company uses regression analysis of historical internal and peer data (as Company loss data is insufficient) to determine suitable credit loss drivers to utilize when modeling lifetime PD and LGD. This analysis also determines how expected PD will be impacted by different forecasted levels of the loss drivers. A similar process is employed to calculate a reserve assigned to off-balance sheet commitments, specifically unfunded loan commitments and letters of credit, and any needed reserve is recorded in reserve for unfunded commitments (“RUC”) on the Consolidated Balance Sheets. For periods beyond which we are able to develop reasonable and supportable forecasts, we revert to the historical loss rate on a straight-line basis over a twelve-month period. For each of these loan segments, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speeds, PD rates, and LGD rates. The modeling of expected prepayment speeds is based on historical internal data. EAD is based on each instrument's underlying amortization schedule in order to estimate the bank's expected credit loss exposure at the time of the borrower's potential default. For our cash flow model, management utilizes and forecasts regional unemployment by using a national forecast and estimating a regional adjustment based on historical differences between the two as the loss driver over our reasonable and supportable period of 18 months and reverts back to a historical loss rate over twelve months on a straight-line basis over the loan's remaining maturity. Unemployment projections materially inform our CECL economic forecast and resulted in a reduction to our ACL during the three months ended March 31, 2022. Management leverages economic projections from reputable and independent third parties to inform its loss driver forecasts over the forecast period. While our methodology in establishing the ACL attributes portions of the ACL and RUC to the separate loan pools or segments, the entire ACL and RUC is available to absorb credit losses expected in the total loan portfolio and total amount of unfunded credit commitments, respectively. Portfolio segments are used to pool loans with similar risk characteristics and align with our methodology for measuring expected credit losses. A summary of our primary portfolio segments is as follows: Commercial. The commercial loan portfolio comprises lines of credit and term loans for working capital, equipment, and other business assets across a variety of industries. These loans are used for general corporate purposes including financing working capital, internal growth, and acquisitions; and are generally secured by accounts receivable, inventory, equipment and other assets of our clients' businesses. Paycheck Protection Program ("PPP") . The PPP portfolio comprises loans issued under the SBA's Paycheck Protection Program to support small businesses impacted by the pandemic. PPP loans are approved subject to limited underwriting criteria following SBA guidelines, are unsecured, and are fully guaranteed as to principal and interest by the SBA. Income producing commercial real estate. Income producing commercial real estate loans comprise permanent and bridge financing provided to professional real estate owners/managers of commercial and residential real estate projects and properties who have a demonstrated record of past success with similar properties. Collateral properties include apartment buildings, office buildings, hotels, mixed-use buildings, retail, data centers, warehouse, and shopping centers. The primary source of repayment on these loans is generally expected to come from lease or operation of the real property collateral. Income producing commercial real estate loans are impacted by fluctuation in collateral values, as well as rental demand and rates. Owner occupied – commercial real estate. The owner occupied commercial real estate portfolio comprises permanent financing provided to operating companies and their related entities for the purchase or refinance of real property wherein their business operates. Collateral properties include industrial property, office buildings, religious facilities, mixed-use property, health care and educational facilities. Real estate mortgage – residential . Real estate mortgage residential loans comprise consumer mortgages for the purpose of purchasing or refinancing first lien real estate loans secured by primary-residence, second-home, and rental residential real property. Construction – commercial and residential. The construction commercial and residential loan portfolio comprises loans made to builders and developers of commercial and residential property, for both renovation, new construction, and development projects. Collateral properties include apartment buildings, mixed use property, residential condominiums, single and 1-4 residential property, and office buildings. The primary source of repayment on these loans is expected to come from the sale, permanent financing, or lease of the real property collateral. Construction loans are impacted by fluctuations in collateral values and the ability of the borrower or ultimate purchaser to obtain permanent financing. Construction – commercial and industrial ("C&I") (owner occupied) . The construction C&I (owner occupied) portfolio comprises loans to operating companies and their related entities for new construction or renovation of the real or leased property in which they operate. Generally these loans contain provisions for conversion to an owner occupied commercial real estate loan or to a commercial loan after completion of construction. Collateral properties include industrial, healthcare, religious facilities, restaurants, and office buildings. Home equity . The home equity portfolio comprises consumer lines of credit and loans secured by subordinate liens on residential real property. Other consumer. The other consumer portfolio comprises consumer purpose loans not secured by real property, including personal lines of credit and loans, overdraft lines, and vehicle loans. This category also includes other loan items such as overdrawn deposit accounts as well as loans and loan payments in process. We have several pass credit grades that are assigned to loans based on varying levels of risk, ranging from credits that are secured by cash or marketable securities, to watch credits which have all the characteristics of an acceptable credit risk but warrant more than the normal level of monitoring. Special mention loans are those that are currently protected by the sound worth and paying capacity of the borrower, but that are potentially weak and constitute an additional credit risk. These loans have the potential to deteriorate to a substandard grade due to the existence of financial or administrative deficiencies. Substandard loans have a well-defined weakness or weaknesses that jeopardizes the liquidation of the debt. They are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected. Some substandard loans are inadequately protected by the sound worth and paying capacity of the borrower and of the collateral pledged and may be considered impaired. Substandard loans can be accruing or can be on nonaccrual depending on the circumstances of the individual loans. Loans classified as doubtful have all the weaknesses inherent in substandard loans with the added characteristics that the weaknesses make collection in full highly questionable and improbable. The possibility of loss is extremely high. All doubtful loans are on nonaccrual. Classified loans represent the sum of loans graded substandard and doubtful. The methodology used in the estimation of the allowance, which is performed at least quarterly, is designed to be dynamic and responsive to changes in portfolio credit quality and forecasted economic conditions. Changes are reflected in the allowance on collectively assessed and individually assessed loans as the collectability of classified loans is evaluated with new information. As our portfolio has matured, historical loss ratios have been closely monitored. The review of the appropriateness of the allowance is performed by executive management and presented to management committees, Credit Oversight Committee (which replaced Directors Loan Committee), the Audit Committee, and the Board of Directors. The committees' reports to the Board are part of the Board review on a quarterly basis of our consolidated financial statements. When management determines that foreclosure is probable, and for certain collateral-dependent loans where foreclosure is not considered probable, expected credit losses are based on the estimated fair value of the collateral adjusted for selling costs, when appropriate. A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals and modifications unless management has a reasonable expectation that a loan will be in a trouble debt restructuring. We do not measure an ACL on accrued interest receivable balances because these balances are written off in a timely manner as a reduction to interest income when loans are placed on nonaccrual status.
Collateral Dependent Financial Assets	Collateral Dependent Financial Assets Loans that do not share risk characteristics are evaluated on an individual basis. For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the net present value ("NPV") from the operation of the collateral. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. A loan that has been modified or renewed is considered a TDR when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics. The Company's ACL reflects all effects of a TDR when an individual asset is specifically identified as a reasonably expected TDR. The Company has determined that a TDR is reasonably expected no later than the point when the lender concludes that modification is the best course of action and it is at least reasonably possible that the troubled borrower will accept some form of concession from the lender to avoid a default. Reasonably expected TDRs and executed non-performing TDRs are evaluated individually to determine the required ACL. Refer to the subsection above "Lendi ng operations and accommodations to borrowers" for a discussion on the impact of the CARES Act on TDRs.
Allowance for Credit Losses - Available-for-Sale Debt Securities	Allowance for Credit Losses - Available-for-Sale Debt Securities The Company utilizes ASC 326 to evaluate its available-for-sale ("AFS") debt security portfolio for expected credit losses. For AFS debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis. If either criterion is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an ACL is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an ACL is recognized in other comprehensive income, as a non-credit-related impairment. The entire amount of an impairment loss is recognized in earnings only when: (1) the Company intends to sell the security; or (2) it is more likely than not that the Company will have to sell the security before recovery of its amortized cost basis; or (3) the Company does not expect to recover the entire amortized cost basis of the security. In all other situations, only the portion of the impairment loss representing the credit loss must be recognized in earnings, with the remaining portion being recognized in shareholders' equity as comprehensive income, net of deferred taxes. Changes in the allowance for credit losses are recorded as a provision for (or reversal of) credit losses. Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Any impairment not recorded through an allowance for credit loss is recognized in other comprehensive income as a non-credit-related impairment. We have made a policy election to exclude accrued interest from the amortized cost basis of available-for-sale debt securities and report accrued interest separately in other assets in the Consolidated Balance Sheets. Available-for-sale debt securities are placed on nonaccrual status when we no longer expect to receive all contractual amounts due, which is generally at 90 days past due. Accrued interest receivable is reversed against interest income when a security is placed on nonaccrual status. Accordingly, we do not recognize an allowance for credit loss against accrued interest receivable.
Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures	Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial instruments include off-balance sheet credit instruments such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records a reserve for unfunded commitments ("RUC") on off-balance sheet credit exposures through a charge to provision for credit loss expense in the Company's Consolidated Statement of Income. The RUC on off-balance sheet credit exposures is estimated by loan segment at each balance sheet date under the current expected credit loss model using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur, and is included in the RUC on the Company's Consolidated Balance Sheet. The following table presents a breakdown of the provision for credit losses included in our Consolidated Statements of Income for the applicable periods (in thousands): Three Months Ended March 31, (dollars in thousands) 2022 2021 Provision for (reversal of) credit losses- loans $ (3,001) $ (2,261) Provision for (reversal of) credit losses- HTM debt securities 817 — Provision for (reversal of) credit losses- AFS debt securities (603) (89) Total $ (2,787) $ (2,350) These statements should be read in conjunction with the audited Consolidated Financial Statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2021.
Other New Authoritative Accounting Guidance	Other New Authoritative Accounting Guidance Accounting Standards Adopted in 2022 : ASU No. 2020-06, " Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity " ("ASU 2020-06") simplifies accounting for convertible instruments by removing major separation models required under current U.S. GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument and more convertible preferred stock as a single equity instrument with no separate accounting for embedded conversion features. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. ASU 2020-06 also simplifies the diluted earnings per share (EPS) calculation in certain areas. In addition, the amendment updates the disclosure requirements for convertible instruments to increase the information transparency. For public business entities, excluding smaller reporting companies, the amendments in ASU 2020-06 are effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. ASU 2020-06 did not have a material impact on the Company's consolidated financial statements. Accounting Standards Pending Adoption: ASU No. 2020-4, " Reference Rate Reform (Topic 848)" ("ASU 2020-4") provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. For transactions that are modified because of reference rate reform and that meet certain scope guidance (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered "minor" so that any existing unamortized origination fees/ costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. ASU 2020-4 also provides numerous optional expedients for derivative accounting. ASU 2020-4 is effective March 12, 2020 through December 31, 2022. An entity may elect to apply ASU 2020-4 for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected for a Topic or an Industry Subtopic within the Codification, the amendments in this ASU must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. We anticipate this ASU will simplify any modifications we execute between the selected start date (yet to be determined) and December 31, 2022 that are directly related to LIBOR transition by allowing prospective recognition of the continuation of the contract, rather than extinguishment of the old contract resulting in writing off unamortized fees/costs. We do not anticipate that the LIBOR transition or the application of this ASU will have material effects on the Company's business operations and consolidated financial statements. ASU No. 2022-02, " Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures " ("ASU 2022-02") eliminates the accounting guidance for troubled debt restructurings ("TDRs") while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty that assess whether a modification has created a new loan. Additionally, ASU 2022-02 requires that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases. For entities that have adopted ASC 326, the amendments in the ASU are effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years. The impact of ASU 2022-02 should be applied prospectively, or, for the recognition and measurement of TDRs, with a modified retrospective transition method. We are currently in the process of evaluating this guidance.
