Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation The accompanying consolidated financial statements and notes thereto of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-K and conform to practices within the banking industry and include all of the information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for financial reporting.
Principles of Consolidation and Nature of Operations, Policy [Policy Text Block] | Principles of Consolidation and Nature of Operations The accompanying consolidated financial statements include the accounts of RBB Bancorp and its wholly-owned subsidiaries RBB and RAM. All significant intercompany transactions have been eliminated. RBB Bancorp has no significant business activity other than its investments in the Bank and in RAM. However, through our whole bank acquisition activity, we have acquired three statutory business trusts: TFC Statutory Trust, FAIC Statutory Trust and PGB Capital Trust I. These trusts issued trust preferred securities representing undivided preferred beneficial interests in the assets of these trusts. The proceeds of these trust preferred securities were invested in certain securities issued by the entities we have acquired, with similar terms to the relevant series of securities issued by these trusts, which we refer to as subordinated debentures, and are included in Tier 2 capital. The parent company only condensed financial information on RBB Bancorp is provided in Note 22. In connection with the 2018 acquisition of First American International Corp (“FAIC”), the Company acquired FAIB Capital Corp. (“FAICC”), a real estate investment trust formed on August 28, 2013 as a New York State corporation, which operates as a wholly-owned subsidiary of the Bank.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. It is reasonably possible that these estimates could change as actual results could differ from those estimates. The allowance for credit losses, realization of deferred tax assets, the valuation of goodwill and other intangible assets, other derivatives, and the fair value measurement of financial instruments are particularly subject to change and such change could have a material effect on the consolidated financial statements.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash and Cash Equivalents Cash and cash equivalents include cash and due from banks, term federal funds sold and interest-bearing deposits in other financial institutions with original maturities of less than 90 days. Net cash flows are reported for customer loan and deposit transactions and interest-bearing deposits in other financial institutions.
Cash and Due from Banks, Policy [Policy Text Block] | Cash and Due from Banks Banking regulations require that banks maintain a percentage of their deposits as reserves in cash or on deposit with the Federal Reserve Bank. There were no reserves required to be held as of December 31, 2023 and 2022. The Company maintains amounts in due from bank accounts, which may exceed federally insured limits. The Company has not experienced any losses in such accounts.
Interest-bearing Deposits in Other Financial Institutions, Policy [Policy Text Block] | Interest-Earning Deposits in Other Financial Institutions Interest-bearing deposits in other financial institutions not included in cash and cash equivalents are carried at cost and generally mature in one year or less.
Marketable Securities, Policy [Policy Text Block] | Investment Securities Investment 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. Debt securities not classified as held to maturity are classified as available for sale. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premiums or discounts. Premiums and discounts on securities are amortized on the level-yield method to the earlier of the maturity date or call date of the underlying securities. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Prior to January 1, 2022, management evaluated debt securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considered the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assessed whether it intended to sell, or it was more likely than not that it would be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell was met, the entire difference between amortized cost and fair value was recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment was split into two components as follows; OTTI related to credit loss, which must be recognized in the income statement and; OTTI related to other factors, which was recognized in other comprehensive income. The credit loss was defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. Effective January 1, 2022, upon the adoption of ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), the Company accounts for credit losses on available for sale securities in accordance with ASC 326-30. Debt securities are measured at fair value and subject to impairment testing. When a debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit loss by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components of the fair value change. If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation reserve would be reduced, but not more than the amount of the current existing reserve for that security. For available-for-sale 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 of the criteria regarding intent or requirement to sell is met, then the security’s amortized cost basis is written down to fair value through income. For debt securities available-for-sale 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, then the present value of cash flows expected to be collected from the security are 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, then a credit loss exists and an allowance for credit losses 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 allowance for credit losses is recognized in other comprehensive income (loss). Changes in the allowance for credit losses are recorded as credit loss expense (or reversal). Losses are charged against the allowance when management believes the uncollectibility of an available-for-sale security is confirmed or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available-for-sale debt securities totaled $919,000 and $759,000 at December 31, 2023 and 2022, and is excluded from the estimate of credit losses. Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type. Accrued interest receivable on held-to-maturity debt securities totaled $43,000 and $51,000 at December 31, 2023 and 2022, and is excluded from the estimate of credit losses.
Financing Receivable, Held-for-Sale [Policy Text Block] | Loans Held For Sale Mortgage loans originated or acquired and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Loans held for sale consist primarily of first trust deed mortgages on single-family residential properties located in California and New York. Mortgage loans held for sale are generally sold with servicing rights retained. The carrying value of mortgage loans sold is determined by reducing the amount allocated to the servicing right, when applicable. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loans sold.
Financing Receivable [Policy Text Block] | Loans Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding unpaid principal balances reduced by any charge-offs and net of any deferred fees or costs on originated loans, or unamortized premiums or discounts on purchased loans. Loan origination fees and certain direct origination costs are deferred and recognized in interest income using the level-yield method without anticipating prepayments. Premiums and discounts on loans purchased are grouped by type and certain common risk characteristics and amortized or accreted as an adjustment of yield over the weighted-average remaining contractual lives of each group of loans, adjusted for prepayments when applicable, using methodologies which approximate the interest method. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is discontinued when principal or interest is past due 90 days or when, in the opinion of management, there is reasonable doubt as to collectability based on contractual terms of the loan. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Income on nonaccrual loans is subsequently recognized only to the extent that cash is received and the loan's principal balance is deemed collectible. Interest accruals are resumed on such loans only when they are brought current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to all principal and interest.
Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block] | Allowance for Credit Losses - Loans Effective January 1, 2022, upon the adoption of ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), the Company accounts for credit losses on loans in accordance with ASC 326, which requires the Company to record an estimate of expected lifetime credit losses for loans at the time of origination. The allowance for credit losses (“ACL”) is maintained at a level deemed appropriate by management to provide for expected credit losses in the loan portfolio as of the date of the consolidated balance sheet. Estimating expected credit losses requires management to use relevant forward-looking information, including the use of reasonable and supportable forecasts. The measurement of the ACL is performed by collectively evaluating loans with similar risk characteristics. The Company has elected to utilize a DCF approach for all segments except for consumer loans and loans to non-depository financial institutions, which use a remaining life approach. The Company’s DCF methodology incorporates a probability of default, loss given default and exposure at default model, as well as expectations of future economic conditions, using reasonable and supportable forecasts. The Company uses both internal and external qualitative factors within the current expected credit losses (“CECL”) model including: lending policies, procedures, and strategies; changes in nature and volume of the portfolio; credit and lending personnel experience; changes in volume and trends in classified loans, delinquencies, and nonaccrual; concentration risk; collateral values; regulatory and business environment; loan review results; and economic conditions. The Company determines the weighting of the qualitative factors based on management’s ability to directly control or influence the level of risk exposure. The factors related to economic conditions, collateral values, and the regulatory and business environment were assigned a higher allocation, and the remaining factors related to internal conditions received a lower allocation. Management further estimates the allowance balance required using past loan loss experience from peers with similar portfolio sizes and geographic locations to the Company, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. The Company’s CECL methodology utilizes a four-quarter reasonable and supportable forecast period, and a four-quarter reversion period. The Company is using the Federal Open Market Committee to obtain forecasts for the unemployment rate, while reverting to a long-run average of each considered economic factor. The Company records a liability for lifetime expected credit losses on off-balance-sheet credit exposure that do not fit the definition of unconditionally cancelable in accordance with ASC 326. The Company uses the loss rate and exposure of default framework to estimate a reserve for unfunded commitments. Loss rates for the expected funded balances are determined based on the associated pooled loan analysis loss rate and the exposure at default is based on an estimated utilization given default. The Company assesses expected credit losses for individual instruments that have different risk characteristics than those that are evaluated on a collective (pooled) basis, in accordance with ASC 326. An individual analysis will provide a specific reserve for instruments involved with fair market value of collateral or present value of future cash flow. In such a manner, the Bank performs individual analysis on loans that are 90 or more days past due, on non-accrual status or modified loans. Credit losses are not estimated for accrued interest receivable as interest that is deemed uncollectible is written off through interest income. The Company adopted ASU 2022-02, Financial Instruments—Credit Losses (Topic 326), effective January 1, 2023. Upon adoption, the Company evaluates all receivable modifications under ASC 310 to determine whether a modification made to a borrower results in a new loan or a continuation of the existing loan. The Company no longer considers renewals, modifications, or extensions resulting from reasonably expected troubled debt restructurings (“TDRs”) when calculating the allowance for credit losses under ASC 326. The post-modification effective interest rate is used to calculate the allowance for credit losses when the DCF method is applied. Allowance for Loan Losses (prior to January 1, 2022) Prior to the Company's adoption of ASC 326, Financial Instruments—Credit Losses, on January 1, 2022, the Company maintained an allowance for loan losses (“ALL”) in accordance with ASC 450, Contingencies, and ASC 310, Receivables. The ALL was a valuation allowance for probable incurred credit losses. Loan losses were charged against the allowance when management believed the uncollectibility of a loan balance was confirmed. Subsequent recoveries, if any, were credited to the allowance. Management estimated the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations, estimated collateral values, economic conditions, and other factors. Allocations of the allowance may have been made for specific loans, but the entire allowance was available for any loan that, in management's judgment, should be charged-off. Amounts were charged-off when available information confirmed that specific loans or portions thereof, were uncollectible. This methodology for determining charge-offs was consistently applied to each segment.
Transfers and Servicing of Financial Assets, Transfers of Financial Assets, Sales, Policy [Policy Text Block] | Servicing Rights Servicing rights are established as an intangible asset when mortgage loans and SBA loans are sold with servicing retained and they are initially recorded at fair value with the income statement effect recorded in the gain on sale of loans. Fair value is based on a valuation model that calculates the present value of estimated future net servicing income. All classes of servicing assets are subsequently measured using the amortization method, which requires servicing rights to be amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. Quarterly impairment is based upon the fair value of the rights as compared to carrying amount. Impairment is recognized through a charge to income to establish a valuation allowance for an individual grouping, to the extent that fair value is less than the carrying amount. If the Company later determines that all or a portion of the impairment no longer exists for a particular grouping, a reduction of the allowance may be recorded as an increase to income. The estimated fair value of the servicing rights is obtained through independent third party valuations based on an analysis of future cash flows, incorporating key assumptions including discount rates, prepayment speeds and interest rates. Servicing fee income, which is reported on the income statement as loan servicing fees, net of amortization, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal. The amortization of the mortgage and SBA servicing rights is offset against loan servicing fee income and reported as a net amount in the consolidated income statement.
Transfers and Servicing of Financial Assets, Transfers of Financial Assets, Policy [Policy Text Block] | Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Gains on sale of mortgage loans totaled $112,000, $1.2 million, and $7.9 million, and gains on sale of SBA loans totaled $262,000, $696,000, and $2.1 million in 2023, 2022, and 2021, respectively.
Property, Plant and Equipment, Policy [Policy Text Block] | Premises and Equipment Land is carried at cost. Premises, leasehold improvements and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives, which is thirty years for premises and ranges from three to ten years for leasehold improvements and equipment. Leasehold improvements are amortized using the straight-line method over the estimated useful lives of the improvements or the remaining lease term, whichever is shorter. Expenditures for betterments or major repairs are capitalized and those for ordinary repairs and maintenance are charged to operations as incurred.
Lessee, Leases [Policy Text Block] | Operating Lease ROU Assets and Lease Liabilities Operating lease Right-of-Use (“ROU”) assets and lease liabilities are included in other assets and other liabilities, respectively, on the Company’s consolidated balance sheet. The ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The lease terms include periods covered by options to extend or terminate the lease depending on whether the Company is reasonably certain to exercise such options. The Company uses its incremental borrowing rate to determine the present value of its lease liabilities. The ROU asset, at adoption of ASU 2016-02, Leases (Topic 842), was recorded at the amount of the lease liability plus any prepaid rent and initial direct costs, less any lease incentives and accrued rent. Upon adoption of this Topic on January 1, 2021, the Company elected the package of practical expedients that permits the Company to not reassess its prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected all of the new standard’s available transition practical expedients, including the short-term lease recognition exemption that includes not recognizing ROU assets or lease liabilities for existing short-term leases, and the practical expedient to not separate lease and non-lease components for all of the Company’s leases. The Company determines if a contract arrangement is a lease at inception and primarily enters into operating lease contracts for its branch locations, office space, and certain equipment. As part of its property lease agreements, the Company may seek to include options to extend or terminate at lease when it is reasonably certain that the Company will exercise those options. The Company's measurement of the ROU assets and operating lease liabilities does not include payments associated with the option to extend or terminate the lease term unless the Company is reasonably certain to exercise such options then the period will cover the option to extend or terminate. The ROU lease asset also includes any lease payments made and lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company did not possess any leases that have variable lease payments or residual value guarantees as of December 31, 2023.
Other Real Estate Owned, Policy [Policy Text Block] | Other Real Estate Owned Real estate acquired by foreclosure or deed in lieu of foreclosure is recorded at fair value at the date of foreclosure, establishing a new cost basis by a charge to the allowance for credit losses, if necessary. Other real estate owned is carried at the lower of the Company's carrying value of the property or its fair value, less estimated carrying costs and costs of disposition. Fair value is based on current appraisals less estimated selling costs. Any subsequent write-downs are charged against operating expenses and recognized as a valuation allowance. Operating expenses and related income of such properties and gains and losses on their disposition are included in other operating income and expenses.
Goodwill and Intangible Assets, Policy [Policy Text Block] | Goodwill and Other Intangible Assets Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill resulting from whole bank and branch acquisitions is not amortized, but tested for impairment at least annually. The Company has selected October 1 as the date to perform the annual impairment test. Goodwill amounted to $71.5 million as of December 31, 2023 and 2022, and is the only intangible asset with an indefinite life on the balance sheet. No impairment was recognized on goodwill during 2023 and 2022. Goodwill in the amount of $2.3 million was recognized in conjunction with the acquisition of the Hawaii Branch from BOTO. After evaluating the prolonged decrease in the Company’s market value, management performed a quantitative goodwill impairment analysis as of September 30, 2023. Management engaged a third-party valuation specialist to assist with the quantitative analysis. The evaluation used two methods to estimate the value of the Company: the market approach and the income approach. The market approach uses pricing information available on publicly traded companies that are similar to the subject company to determine the value of the subject company. Estimates used in the market approach included selecting a representative peer group of institutions, determining the price to tangible book value based on the results of the peer group institutions, and estimating a control premium based on the whole-bank acquisition prices for representative transactions. The income approach is based on the discounted free cash flows of the subject company using projections of future results, and considering future economic forecasts and management’s plans. Estimates used in the income approach include management’s projections of the Company’s income in future periods and an appropriate rate of return that would be required by a market participant. Based on this quantitative analysis, the fair value of the Company exceeds its carrying amount with a passing amount of 9.6% at September 30, 2023. In addition, due to changes in the Company’s projections of income in future periods during the fourth quarter of 2023 resulting from the current economic environment, at December 31, 2023, management performed certain calculations and sensitivity analyses related to the quantitative goodwill impairment analysis performed at September 30, 2023 and the current information. Based on this most recent analysis, management concluded that goodwill was also not impaired at December 31, 2023. Other intangible assets consist of core deposit intangible (“CDI”) assets arising from acquisitions. CDI assets are amortized on an accelerated method over their estimated useful life of 8 to 10 years. CDI was recognized in the 2013 acquisition of Los Angeles National Bank, in the 2016 acquisition of TFC Holding Company, in the 2018 acquisition of FAIC and in the 2020 acquisition of PGBH. In January 2022, $729,000 of CDI was recognized in conjunction with the Hawaii Branch purchase from BOTO. The following table presents changes in the carrying amount of CDI for the periods indicated:

Bank Owned Life Insurance, Policy [Policy Text Block] | Bank Owned Life Insurance The Company has purchased life insurance policies on a select group of employees and directors. Bank Owned Life Insurance (“BOLI”) is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Increases of the cash value of these policies, as well as insurance proceeds received, are recorded in the other noninterest income and are not subject to income tax for as long as they are held for the life of the covered employees and directors.
Federal Home Loan Bank Stock and Other Equity Securities, Policy [Policy Text Block] | FHLB Stock and Other Equity Securities The Company is a member of the Federal Home Loan Bank (“FHLB”) system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. The Company also owns an equity investment in Pacific Coast Banker’s Bank and Atlantic Community Bankers Bank stock. The Company adopted ASU 2016-01 on January 1, 2019, and elected the measurement alternative for measuring equity securities without readily determinable fair values at cost less impairment, plus or minus observable price changes in orderly transactions. As of December 31, 2023, the Company had several equity investments without readily determinable fair values in the amount of $22.3 million, and $22.2 million at December 31, 2022. There were no impairment charges in 2023 or 2022. There was a $360,000 impairment charge in 2021.
Share-Based Payment Arrangement [Policy Text Block] | Stock-Based Compensation The Company currently recognizes stock-based compensation based on the grant date fair value of equity awards, including stock options, restricted stock units and restricted stock, which have been granted to employees. The expense related to equity-based awards granted to directors or other qualified non-employee awardees is recognized as other noninterest expense. Stock option compensation expense is calculated based on the fair value of the award at the grant date for those options expected to vest and is recognized as an expense over the vesting period of the grant using the straight-line method. The Company uses the Black-Scholes option-pricing model to estimate the value of granted stock options. This model takes into account the option exercise price, the expected life, the current price of the underlying stock, the expected volatility of the Company’s stock, expected dividends on the stock and a risk-free interest rate. The Company estimates the expected volatility based on the Company’s historical stock prices for the period corresponding to the expected life of the stock options. Restricted stock and restricted stock units are valued based on the closing price of the Company’s stock on the date of the grant. Stock-based compensation expense is recognized over the period which an employee is required to provide services in exchange for the award, generally defined as the vesting period. When the options are exercised, the Company’s policy is to issue new shares of stock. The Company’s accounting policy is to recognize forfeitures as they occur.
Income Tax, Policy [Policy Text Block] | Income Taxes Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. The Company files its income taxes on a consolidated basis with its subsidiaries. The allocation of income tax expense represents each entity’s proportionate share of the consolidated provision for income taxes. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in earnings in the period that includes the enactment date. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. Tax effects from an uncertain tax position are recognized in the financial statements only if, based on its merits, the position is more likely than not to be sustained on audit by the taxing authorities. Interest and penalties related to uncertain tax positions are recorded as part of income tax expense. Under ASC 740, a valuation allowance is required to be recognized if it is “more likely than not” that all or a portion of the Company's deferred tax assets will not be realized. The Company's policy is to evaluate the deferred tax assets on a quarterly basis and record a valuation allowance for the Company's deferred tax assets if there is not sufficient positive evidence available to demonstrate utilization of the Company's deferred tax assets. Initial setup or an increase to deferred tax asset valuation allowance would be charged to income tax expense that would negatively impact our earnings.
Postemployment Benefit Plans, Policy [Policy Text Block] | Retirement Plans The Company established a 401(k) plan in 2010. The Company contributed $707,000, $594,000, and $532,000 in 2023, 2022 and 2021, respectively.
Comprehensive Income, Policy [Policy Text Block] | Comprehensive Income Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, net of taxes.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Financial Instruments In the ordinary course of business, the Company enters into financial commitments to meet the financing needs of its customers. These financial commitments include commitments to extend credit, unused lines of credit, commercial and similar letters of credit and standby letters of credit as described in Note 13. Such financial instruments are recorded in the financial statements when they are funded.
Derivatives, Policy [Policy Text Block] | Derivatives Interest Rate Lock Commitments (“IRLCs”) are agreements under which the Company agrees to extend credit to a borrower under certain specified terms and conditions in which the interest rate and the maximum amount of the loan are set prior to funding. Under the agreement, the Company commits to lend funds to a potential borrower (subject to the Company’s approval of the loan) on a fixed or adjustable rate basis, regardless of whether interest rates change in the market, or on a floating rate basis. As such, outstanding IRLCs are subject to interest rate risk and related price risk during the period from the date of issuance through the date of loan funding, cancelling or expiration. Loan commitments generally range between 30 and 90 days; however, the borrower is not obligated to obtain the loan. The Company is subject to fallout risk related to IRLCs, which is realized if approved borrowers choose not to close on the loans within the terms of the IRLCs. The Company uses best efforts commitments to substantially eliminate these risks. Historical commitment-to-closing ratios are considered to estimate the quantity of mortgage loans that will fund within the terms of the IRLCs. ASC 815, Derivatives and Hedging, provides that IRLCs on mortgage loans that will be held for resale are derivatives and must be accounted for at fair value on the balance sheet. ASC 820, Fair Value Measurements and Disclosures, specifies how these derivatives are to be valued. Commitments to originate mortgage loans to be held for investment and other types of loans are generally not derivatives. The Company has elected to account for these obligations at fair value. Forward Mortgage Loan Sale Contracts (“FMLSC”) are utilized to avoid interest rate risk at the time an interest rate lock commitment is made to the buyer. The Company is subject to interest rate and price risk on its mortgage loans held for sale from the loan funding date until the date the loan is sold. Best efforts commitments which fix the forward sales price that will be realized in the secondary market are used to eliminate the interest rate and price risk to the Company. To avoid interest rate risk, the Company will enter into FMLSCs at the time they make an interest rate lock commitment to the buyer. The buyer can enter into mortgage loan sales commitments on a “mandatory” or “best efforts” basis. Mandatory commitments provide that the loan must be delivered or the commitment be “paired off.” In general, best efforts commitments provide that the loan be delivered if and when it closes. Forward commitments, also known as forward loan sales commitments, are considered derivatives under ASC Topic 815, Derivatives and Hedging, because they meet all of the following criteria:
| ● | They have a specified underlying (the contractually specified price for the loans);

See Note 18 for more information and disclosures relating to the Company's derivatives.
Earnings Per Share, Policy [Policy Text Block] | Earnings Per Share (“EPS”) Basic and diluted EPS are calculated using the two-class method since the Company has issued share-based payment awards considered participating securities because they entitle holders the rights to dividends during the vesting term. The two-class method is an earnings allocation formula that determines net income per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Basic EPS excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity.
Fair Value Measurement, Policy [Policy Text Block] | Fair Value Measurement Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Current accounting guidance establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect the Company's own assumptions about the assumptions that market participants would use in pricing an asset or liability. See Note 18 for more information and disclosures relating to the Company's fair value measurements.
Segment Reporting, Policy [Policy Text Block] | Operating Segments Management has determined that since generally all of the banking products and services offered by the Company are available in each branch of the Bank, all branches are located within the same economic environment and management does not allocate resources based on the performance of different lending or transaction activities, it is appropriate to aggregate the Bank branches and report them as a single operating segment.
New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements Recently Adopted In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instrument (Topic 326), including subsequent amendments to this ASU. This ASU changes how entities measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard replaced the “incurred loss” approach with an “expected loss” model. The new model, referred to as the CECL model, applies to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held to maturity securities, loan commitments, and financial guarantees. For available for sale (“AFS”) debt securities with unrealized losses, losses will be recognized as allowances rather than reductions in the amortized cost of the securities. ASU 2016-13 also expands the disclosure requirements regarding an entity's assumptions, models, and methods for estimating the allowance for credit losses. In addition, entities are required to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. The Company retroactively adopted CECL to January 1, 2022 as the Company’s emerging growth company status expired as of December 31, 2022. A one-time cumulative adjustment of $2.1 million was made to the Company’s ACL, which was recorded through retained earnings upon adoption of ASU 2016-13 as of January 1, 2022. The following table sets forth the cumulative effect of the changes to the Company's consolidated balance sheets at January 1, 2022, for the adoption of ASU 2016-13:

In February 2019, the U.S. federal bank regulatory agencies approved a final rule modifying their regulatory capital rules and providing an option to phase in over a three-year period the day-one adverse regulatory capital effects of ASU 2016-13. Additionally, in March 2020, the U.S. federal bank regulatory agencies issued an interim final rule that provided banking organizations that adopted CECL in the 2020 an option to delay the estimated CECL impact on regulatory capital for an additional two years for a total transition period of up to five years to provide regulatory relief to banking organizations to better focus on supporting lending to creditworthy households and businesses in light of recent strains on the U.S. economy as a result of the novel coronavirus disease 2019 (“COVID-19”) pandemic. As a result, entities that adopted CECL in 2020 had the option to gradually phase in the full effect of CECL on regulatory capital over a five-year transition period. For entities who adopted CECL after 2020, the three-year phase-in transition provision is available if any entity experiences a reduction in retained earnings due to CECL adoption as of the beginning of the fiscal year in which the institution adopts CECL and makes an election to use this phase-in option. Effective January 1, 2022, the Company adopted ASU 2016-13, reflected the full effect of CECL at December 31, 2022, and did not elect the three-year CECL phase-in option on regulatory capital. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350). This Update simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. The amendments in this Update are required for public business entities and other entities that have goodwill reported in their financial statements and have not elected the private company alternative for the subsequent measurement of goodwill. As a result, under this Update, “an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.” The Company adopted this ASU on December 31, 2022. Adoption of ASU 2017-04 did not have a significant impact on the Company’s consolidated financial statements. In February 2020, the FASB issued ASU 2020-02, Financial Instruments—Credit Losses (Topic 326) and Leases (Topic 842)—Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 119 and Update to SEC Section on Effective Date Related to Accounting Standards Update No. 2016-02, Leases (Topic 842) (SEC Update). This is an amendment to add the SEC Staff guidance on CECL) to the FASB codification. It contains guidance on what the SEC would expect the Company to perform and document when measuring and recording its allowance for credit losses for financial assets recorded at amortized cost. The Company implemented CECL on January 1, 2022. Upon adoption of CECL, the Company recorded a $2.1 million transition adjustment for the allowance for credit losses through retained earnings. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary optional expedients to ease the financial reporting burdens of the expected market transition from London Interbank Offered Rate (“LIBOR”) to an alternative reference rate such as Secured Overnight Financing Rate (“SOFR”). This pronouncement is applicable to all companies with contracts or hedging relationships that reference an interest rate that is expected to be discontinued. The ASU provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. Companies can apply the ASU immediately. However, the guidance will only be available for a limited time. The optional relief generally does not apply to contract modifications made, sales and transfers of HTM debt securities, and hedging relationships entered into or evaluated after December 31, 2022. The guidance was effective upon issuance and generally can be applied through December 31, 2022. In December 2022, the FASB issued 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, to defer the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which entities will no longer be permitted to apply the relief in Topic 848. The LIBOR termination date was June 30, 2023. The Company converted all loans indexed under LIBOR to CME Term SOFR with relevant spread adjustment as the alternative reference rate beginning on and after July 3, 2023. No LIBOR indexed loans are being originated. The Company has several issuances of LIBOR based long-term debt and subordinated debentures. Refer to Notes 9 and 10 of the Company’s consolidated financial statements included in this Annual Report. In October 2021, the FASB issued ASU 2021-08, Accounting for Contract Assets and Contract Liabilities, to require an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with revenue recognition guidance as if the acquirer had originated the contract. That is, such acquired contracts will not be measured at fair value. The Update is effective for public companies in fiscal years starting after December 15, 2022. The Company adopted ASU 2021-08 on January 1, 2023 and the adoption did not have a material impact on the Company's consolidated financial statements. In March 2022, the FASB issued ASU 2022-02, Financial Instruments-Credit Losses (Topic 326). The standard addresses the following: 1) eliminates the accounting guidance for TDRs, and will require an entity to determine whether a modification results in a new loan or a continuation of an existing loan, 2) expands disclosures related to modifications, and 3) will require disclosure of current period gross write-offs of financing receivables within the vintage disclosures table. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and are applied prospectively, except with respect to the recognition and measurement of TDRs, where an entity has the option to apply a modified retrospective transition method. Early adoption of the amendments in this ASU is permitted. An entity may elect to early adopt the amendments regarding TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. The Company adopted ASU 2022-02 on January 1, 2023 and see Note 5 for the disclosure impact. Recently Issued; Not Yet Effective In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820)—Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. This pronouncement clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. ASU 2022-03 also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction and requires certain new disclosures for equity securities subject to contractual sale restrictions. ASU 2022-03 will be effective for the Company on January 1, 2024. Adoption of ASU 2022-03 is not expected to have a material impact on the Company’s consolidated financial statements. In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323). This Update permits reporting entities to elect to account for their tax equity investments using the proportional amortization method if certain conditions are met. It requires that a liability be recognized for delayed equity contributions that are unconditional and legally binding or for equity contributions that are contingent upon a future event when that contingent event becomes probable. The reporting entity needs to disclose the nature of its tax equity investments and the effect of its tax equity investments on its financial position and results of operations. ASU 2023-02 will be effective for the Company in fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Adoption of ASU 2023-02 is not expected to have a material impact on the Company's consolidated financial statements. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements. This pronouncement amends the FASB Accounting Standards Codification to reflect updates and simplifications to certain disclosure requirements referred to the FASB by the SEC in 2018, including disclosures for the statement of cash flows, earnings per share, commitments, debt and equity instruments, and certain industry information, among other things. Each amendment is effective when the related disclosure is effectively removed from Regulations S-X or S-K; early adoption is prohibited. All amendments should be applied prospectively. If the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K by June 30, 2027, the pending amendments will be removed and will not become effective for any entity. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. This Update enhances the transparency and decision usefulness of income tax disclosures. The amendments in this Update require the following: 1) consistent categories and greater disaggregation of information in the rate reconciliation, and 2) income taxes paid disaggregated by jurisdiction. The amendments in the ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this Update should be applied on a prospective basis. Retrospective application is permitted. Adoption of ASU 2023-09 is not expected to have a material impact on the Company's consolidated financial statements.
