NOTE 1 - BUSINESS DESCRIPTION

RBB Bancorp (“RBB”) is a financial holding company registered under the Bank Holding Company Act of 1956, as amended. RBB Bancorp’s principal business is to serve as the holding company for its wholly-owned banking subsidiaries, Royal Business Bank ("Bank") and RBB Asset Management Company ("RAM"), collectively referred to herein as "the Company". RAM was formed to hold and manage problem assets acquired in business combinations.

At March 31, 2022, the Company had total consolidated assets of $4.0 billion, gross consolidated loans (held for investment and held for sale) of $3.0 billion, total consolidated deposits of $3.2 billion and total consolidated stockholders' equity of $464.8 million. RBB’s common stock trades on the Nasdaq Global Select Market under the symbol “RBB”.

The Bank provides business-banking services to the Chinese-American communities in Los Angeles County, Orange County and Ventura County in California, in Las Vegas, Nevada, the New York City, New York metropolitan area, including Edison, New Jersey, Chicago, Illinois, and Honolulu, Hawaii. Specific services include remote deposit, E-banking, mobile banking, commercial and investor real estate loans, business loans and lines of credit, Small Business Administration (“SBA”) 7A and 504 loans, mortgage loans, trade finance and a full range of depository accounts. The Bank closed its acquisition of the Honolulu, Hawaii branch from Bank of the Orient ("BOTO") on January 14, 2022.

The Company operates full-service banking offices in Arcadia, Cerritos, Diamond Bar, Irvine, Los Angeles, Monterey Park, Oxnard, Rowland Heights, San Gabriel, Silver Lake, Torrance, and Westlake Village, California; Las Vegas, Nevada; Manhattan, Brooklyn, Flushing, and Elmhurst, New York; the Chinatown and Bridgeport neighborhoods of Chicago, Illinois; Edison, New Jersey; and Honolulu, Hawaii. The Company’s primary source of revenue is providing loans to customers, who are predominantly small and middle-market businesses and individuals. On May 2, 2022 we opened our Bensonhurst branch on 86^th Street in Brooklyn, New York.

The Company generates its revenue primarily from interest received on loans and leases and, to a lesser extent, from interest received on investment securities. The Company also derives income from noninterest sources, such as fees received in connection with various lending and deposit services, loan servicing, gain on sales of loans and wealth management services. The Company’s principal expenses include interest expense on deposits and subordinated debentures, and operating expenses, such as salaries and employee benefits, occupancy and equipment, data processing, and income tax expense.

The Company has completed six whole bank acquisitions from July 2011 through January 2022. All of the Company’s acquisitions have been accounted for using the acquisition method of accounting and, accordingly, the operating results of the acquired entities have been included in the consolidated financial statements from their respective acquisition dates. The Company announced the agreement to acquire Gateway Bank F.S.B., and believes the transaction will close in the fourth quarter of 2022.

The Board of Governors of the Federal Reserve System (“Federal Reserve”) announced the reduction of the reserve requirement ratio to zero percent across all deposit tiers, effective March 26, 2020. Depository institutions that were required to maintain deposits in a Federal Reserve bank account to satisfy reserve requirements will no longer be required to do so, and can use the additional liquidity to lend to individuals and businesses. The Federal Reserve has indicated that it may adjust reserve requirement ratios in the future if conditions warrant.

NOTE 2 - BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited 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-Q 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 interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results for the full year. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2021, included in our Annual Report filed on Form 10-K for the fiscal year ended December 31, 2021 and Amendment No. 1 to the Annual Report on Form 10-K/A (collectively our “2021 Annual Report”).

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 our estimate of the allowance for loan losses and the fair value of mortgage servicing rights could change as actual results could differ from those estimates. Actual results could differ from those estimates.

Summary of Significant Accounting Policies

The accompanying unaudited consolidated financial statements were compiled in accordance with the accounting policies set forth in Note 2 – Basis of Presentation and Summary of Significant Policies in our Consolidated Financial Statements as of and for the year ended December 31, 2021, included in our 2021 Annual Report. The Financial Accounting Standards Board ("FASB") issues Accounting Standards Updates ("ASU" or “Update”) and Accounting Standards Codifications (“ASC”), which are the primary source of GAAP.

Recent Accounting Pronouncements

When RBB conducted its initial public offering (“IPO”) in 2017, we qualified as an emerging growth company (“EGC”). We will remain an EGC until the earliest of (i) the end of the fiscal year during which we have total annual gross revenues of $1.0 billion or more, (ii) the end of the fiscal year following the fifth anniversary of the completion of our IPO, (iii) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt and (iv) the date on which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We anticipate no longer qualifying as an EGC on December 31, 2022. EGCs are entitled to reduced regulatory and reporting requirements under the Securities Act of 1933, as amended (the “Securities Act”), and the Exchange Act, as compared to public business entities ("PBE").

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The most significant change for lessees is the requirement under the new guidance to recognize right-of-use assets and lease liabilities for all leases not considered short-term leases, which is generally defined as a lease term of less than 12 months. This change will result in lessees recognizing right-of-use assets and lease liabilities for most leases currently accounted for as operating leases under current lease accounting guidance. Under the new guidance, the Company recognized on the Consolidated Balance Sheets right-of-use assets with a corresponding lease liability. The Company early adopted this ASU on January 1, 2021 and recorded the right-of-use asset and lease liability of approximately $26.8 million.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instrument (Topic 326), including subsequent amending ASUs. This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard will replace today's "incurred loss" approach with an "expected loss" model. The new model, referred to as the current expected credit loss ("CECL") model, will apply 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, entities will measure credit losses in a manner similar to what they do today, except that the 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 loan and lease losses. In addition, public business entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU 2016-13 was originally proposed to be effective for interim and annual reporting periods for an emerging growth company beginning after December 15, 2020, but was subsequently extended until December 31, 2022. Entities will apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company has begun its evaluation of the impact of the implementation of ASU 2016-13. The implementation of the provisions of ASU 2016-13 will most likely impact the Company’s consolidated financial statements as to the level of reserves that will be required for credit losses. The Company will continue to assess the potential impact that this Update will have on the Company’s consolidated financial statements. The Company will adopt CECL (ASU 2016-13) on December 31, 2022.

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 provides banking organizations 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 will have the option to gradually phase in the full effect of CECL on regulatory capital over a five-year transition period. At this point, RBB does not expect to take the option to phase in effect of CECL.

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.” For PBE's, ASU 2017-04 is effective for annual and any interim impairment tests performed in periods beginning after December 15, 2019. As an EGC, the Company will adopt this ASU on December 31, 2022. Adoption of ASU 2017-04 is not expected to have a significant impact on the Company’s consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This Update provides additional guidance to ASU 2015-05, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement” (CCA), on the accounting for implementation, setup, and other upfront costs (collectively referred to as implementation costs) apply to entities that are a customer in a hosting arrangement. This Update applies to entities that are a customer in a hosting arrangement that is a service contract. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. This Update also requires the customer to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. This Update is effective for an EGC for annual reporting periods beginning after December 15, 2020, and interim periods within annual periods beginning after December 15, 2021. Early adoption of the amendments in this Update is permitted, including adoption in any interim period, for all entities. The amendments in this Update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. This Update will most likely not have a material impact unless the Company incurs implementation costs for a CCA that is a service contract.

In January 2020, the FASB issued ASU 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)”. This ASU is for equity securities accounted for by the equity method. The amendment clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The Company has equity securities on our balance sheet but are not material to be considered for the equity method. For an EGC, this ASU is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The Company adopted this ASU on January 1, 2022 and this ASU did not have a material 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. As an EGC, the Company will implement CECL on December 31, 2022.

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 (generally through December 31, 2022). For contract modifications, companies can account for the modification as a continuation of the existing contract without additional analysis. For held-to-maturity (“HTM”) debt securities, one-time sale and/or transfer to available-for-sale or trading may be made for HTM debt securities that both reference an eligible reference rate and were classified as HTM before January 1, 2020. Regarding the effective date and transition: (1) companies can apply the ASU as of the beginning of the interim period that includes March 12, 2020 (e.g. January 1, 2020 for calendar year-end companies) or any date thereafter, (2) the ASU applies prospectively to contract modifications and hedging relationships, and (3) the one-time election to sell and/or transfer debt securities classified as HTM may be made at any time after March 12, 2020. 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. Of the Company’s $3.0 billion in total gross loans as of March 31, 2022, approximately 6.8% have a LIBOR based reference rate. 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 Form 10-Q. The Company is developing new SOFR-based loan products that will be equivalent to prior LIBOR-based loan products. We anticipate a neutral financial impact.

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 ASU is potentially material to the Company, depending on the materiality of an acquired contract asset or liability. The Update is effective for public companies in fiscal years starting after December 15, 2022. Early adoption is permitted. This ASU will be effective for the Company on January 1, 2023.

In November 2021, the FASB issued ASU 2021-10 "Disclosures by Business Entities about Government Assistance". The amendments in this Update require the annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. This Update is applicable to the Company and was adopted January 1, 2022.

In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. This pronouncement eliminates the accounting guidance on troubled debt restructurings ("TDRs") for creditors and amends the guidance on “vintage disclosures” to require disclosure of current-period gross write-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty. As the Company will adopt ASU 2016-13 (“CECL”) on December 31, 2022, ASU 2022-02 will also be effective for the Company on December 31, 2022.

NOTE 3 – ACQUISITION

Honolulu, Hawaii Branch Purchase

On January 14, 2022, the Bank completed the acquisition of the Honolulu, Hawaii branch office of BOTO. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of January 14, 2022. The total fair value of assets acquired approximated $8.5 million, which included $312,000 in cash and cash equivalents, $7.4 million in selected performing loans, $729,000 in core deposit intangible assets and $64,000 in other assets. The total fair value of liabilities assumed was $81.8 million, which included $81.7 million in deposits, $27,000 in certificate of deposit premium, and $90,000 in other liabilities. The Bank received $71.0 million in cash in connection with the acquisition which represented consideration for the deposits assumed by the Bank, partially offset by the purchase price of the assets acquired and the premium paid. Goodwill of $2.3 million and core deposit premium of $729,000 was recognized from the Honolulu branch purchase.

The Company acquired this branch to strategically establish a presence in the Hawaiian Islands area. Goodwill in the amount of $2.3 million was recognized in this acquisition. Goodwill represents the future economic benefits arising from net assets acquired that are not individually identified and separately recognized and is attributable to synergies expected to be derived from the combination of the two entities. Goodwill is not deductible for income tax purposes.

The following table represents the assets acquired and liabilities assumed of the BOTO Honolulu branch as of January 14, 2022 and the fair value adjustments and amounts recorded by the Company under the acquisition method of accounting:

	$	8,088		$	407
Cash received								71,040
Goodwill recognized							$	2,255

The fair values are estimates and are subject to adjustment for up to one year after the acquisition date.

The Company accounted for this transaction under the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires purchased assets and liabilities assumed to be recorded at their respective fair values at the date of acquisition.

The loan portfolio of the Honolulu branch was recorded at fair value at the date of acquisition with the assistance of a third-party valuation. A valuation of the loan portfolio was performed as of the acquisition date to assess the fair value of the loan portfolio. The loan portfolio was segmented into two groups; loans with credit deterioration and loans without credit deterioration, and then split further by loan type. There were no loans acquired with credit deterioration. The fair value was calculated on an individual loan basis using a discounted cash flow analysis. The discount rate utilized was based on a weighted average cost of capital, considering the cost of equity and cost of debt. Also factored into the fair value estimates were loss rates, recovery period and prepayment rates based on industry standards.

The Company also determined the fair value of the core deposit intangible, premises and equipment and deposits with the assistance of third-party valuations.

The core deposit intangible on non-maturing deposits was determined by evaluating the underlying characteristics of the deposit relationships, including customer attrition, deposit interest rates, service charge income, overhead expense and costs of alternative funding. Since the fair value of intangible assets are calculated as if they were stand-alone assets, the presumption is that a hypothetical buyer of the intangible asset would be able to take advantage of potential tax benefits resulting from the asset purchase. The value of the benefit is the present value over the period of the tax benefit, using the discount rate applicable to the asset.

In determining the fair value of certificates of deposit, a discounted cash flow analysis was used, which involved present valuing the contractual payments over the remaining life of the certificates of deposit at market-based interest rates.

Third-party acquisition related expenses are recognized as incurred and continue until the acquired system is converted and operational functions become fully integrated. The Company incurred third-party acquisition related expenses in the consolidated statements of income for the periods indicated in the Statements of Income in the expense item “Merger expenses”.

For the Honolulu branch, during the first quarter of 2022, revenue was $96,000 and the net loss was $87,000.

Unrealized losses have not been recognized into income because the issuer bonds are of high credit quality, management does not intend to sell, it is not more likely than not that management would be required to sell the securities prior to their anticipated recovery and the decline in fair value is largely due to changes in interest rates. The fair value is expected to recover as the bonds approach maturity.

Management evaluates securities for other-than-temporary impairment (“OTTI”) on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss, and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or it is more likely than not that it will 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 is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings.

Equity Securities - The Company has several CRA equity investments. The Company recorded no loss nor gain for the three months ended March 31, 2022 and a loss of $20,000 for the three months ended March 31, 2021 due to the decrease in the fair value of those equity investments without readily determinable fair values. CRA equity securities were $20.0 million as of March 31, 2022 and December 31, 2021.

NOTE 5 - LOANS AND ALLOWANCE FOR LOAN LOSSES

The Company's loan portfolio consists primarily of loans to borrowers within the Southern California metropolitan area, the New York City metropolitan area, the Chicago, Illinois metropolitan area, Las Vegas, Nevada, Edison, New Jersey and Honolulu, Hawaii. Although the Company seeks to avoid concentrations of loans to a single industry or based upon a single class of collateral, real estate and real estate associated businesses are among the principal industries in the Company's market area and, as a result, the Company's loan and collateral portfolios are, to some degree, concentrated in those industries.

The following tables present the balance and activity related to the allowance for loan losses for held for investment loans by type for the periods presented.

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as current financial information, historical payment experience, collateral adequacy, credit documentation, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis typically includes larger, non-homogeneous loans such as commercial real estate and commercial and industrial loans. This analysis is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings:

Pass - Loans classified as pass include loans not meeting the risk ratings defined below.

Special Mention - Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date.

Substandard - Loans classified as substandard are inadequately protected by the current net 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 institution will sustain some loss if the deficiencies are not corrected.

Impaired - A loan is considered impaired, when, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Additionally, all loans classified as troubled debt restructurings are considered impaired.

The risk category of loans by class of loans was as follows at March 31, 2022 and December 31, 2021:

No interest income on non-accrual loans was recognized on a cash basis for the three months ended March 31, 2022 and 2021 or for the year ended December 31, 2021.

The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), signed into law on March 27, 2020, permits financial institutions to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that would otherwise be characterized as troubled debt restructurings ("TDRs") and suspend any determination related thereto if (i) the loan modification is made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the coronavirus emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. The Consolidated Appropriations Act (“CAA”), signed into law on December 27, 2020, extends the applicable period to include modifications to loans held by financial institutions executed between March 1, 2020 and the earlier of (i) January 1, 2022 or (ii) 60 days after the date of the termination of the COVID-19 national emergency. In addition, federal bank regulatory authorities have issued guidance to encourage financial institutions to make loan modifications for borrowers affected by COVID-19 and have assured financial institutions that they will neither receive supervisory criticism for such prudent loan modifications, nor be required by examiners to automatically categorize COVID-19-related loan modifications as TDRs. The Company is applying this guidance to qualifying loan modifications.

The Company identified seven loans as TDRs at March 31, 2022 and nine loans at December 31, 2021, with aggregate balances of $3.2 million and $3.4 million, respectively. Non-accrual TDRs were $1.6 million and $1.7 million at March 31, 2022 and December 31, 2021, respectively. There were $2,000 and $3,000 specific reserves allocated to such loans as of March 31, 2022 and December 31, 2021, respectively. There are no commitments to lend additional amounts at March 31, 2022 and December 31, 2021 to customers with outstanding loans that are classified as TDRs. There were no non-accrual loans that were modified as TDRs during the past twelve months that had payment defaults during the periods.

There were no loans modified as TDRs during the three months ended March 31, 2022 and 2021.

NOTE 6 - LOAN SERVICING

Mortgage, SBA and CRE loans serviced for others are not reported as assets. The principal balances at March 31, 2022 and December 31, 2021 are as follows:

	*March 31,*		*December 31,*
*(dollars in thousands)*	*2022*		*2021*
Loans serviced for others:
Mortgage loans	$	1,236,179	$	1,308,672
SBA loans		142,023		138,173
Commercial real estate loans		4,050		4,070

The fair value of servicing assets for mortgage loans was $16.3 million and $15.4 million at March 31, 2022 and December 31, 2021, respectively. The fair value of servicing assets for SBA loans was $4.1 million and $4.1 million at March 31, 2022 and December 31, 2021, respectively. Estimates of the loan servicing asset fair value are derived through a discounted cash flow analysis. Portfolio characteristics include loan delinquency rates, age of loans, note rate and geography. The assumptions embedded in the valuation are obtained from a range of metrics utilized by active buyers in the market place. The analysis accounts for recent transactions, and supply and demand within the market.

Servicing fees net of servicing asset amortization totaled $432,000 and $246,000 for the three months ended March 31, 2022 and 2021, respectively.

When mortgage and SBA loans are sold with servicing retained, servicing rights are initially recorded at fair value with the income statement effect recorded in gains on sales 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.

Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. Impairment is recognized through 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. During the three months ended March 31, 2022 and 2021, the Company did not record any impairment writedowns on mortgage servicing rights.

Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal. The amortization of mortgage servicing rights is netted against loan servicing fee income.

Goodwill and Intangible Assets Disclosure [Text Block]

NOTE 7 - GOODWILL AND INTANGIBLES

Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any non-controlling 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 are tested for impairment at least annually. The Company has historically selected December 31st as the date to perform the annual impairment test. Goodwill amounted to $71.5 million and $69.2 million at March 31, 2022 and at December 31, 2021, respectively, and is the only intangible asset with an indefinite life on the Company's balance sheet. Goodwill in the amount of $2.3 million was recognized in conjunction with the acquisition of the Honolulu, Hawaii branch office.

Other intangible assets consist of core deposit intangible ("CDI") assets arising from whole bank and branch acquisitions. CDI assets are amortized on an accelerated method over their estimated useful life of 8 to 10 years. During the quarter ended March 31, 2022, $729,000 of CDI was recognized in conjunction with for the Hawaii branch purchase. The unamortized balance at March 31, 2022 and December 31, 2021 was $4.5 million and $4.1 million, respectively. CDI amortization expense was $279,000 and $301,000 for the three months ended March 31, 2022 and 2021, respectively.

Subordinated Borrowings Disclosure [Text Block]

NOTE 10 - SUBORDINATED DEBENTURES

The Company, through the acquisition of TFC Holding Company (“TFC”) in 2016, acquired TFC Statutory Trust (the “Trust”). The Trust conducted a pooled private offering of 5,000 trust preferred securities with a liquidation amount of $1,000 per security. TFC issued $5 million of subordinated debentures to the Trust in exchange for ownership of all of the common securities of the Trust and the proceeds of the preferred securities sold by the Trust. The Company is not considered the primary beneficiary of this Trust (variable interest entity), therefore the Trust is not consolidated in the Company's financial statements, but rather the subordinated debentures are shown as a liability at market value as of the close of the acquisition, which was $3.3 million. There was a $1.9 million valuation reserve recorded to arrive at market value, which is treated as a yield adjustment and is amortized over the life of the security. The Company also purchased an investment in the common stock of the Trust for $155,000, which is included in other assets. The Company may redeem the subordinated debentures, subject to prior approval by the Federal Reserve on or after March 15, 2012, at 100% of the principal amount, plus accrued and unpaid interest. The subordinated debentures mature on March 15, 2037. The Company has the option to defer interest payments on the subordinated debentures from time to time for a period not to exceed five consecutive years. The Company has been paying interest on a quarterly basis. The subordinated debentures may be included in Tier I capital (with certain limitations applicable) under current regulatory guidelines and interpretations. The subordinated debentures have a variable rate of interest equal to three month LIBOR plus 1.65%, which was 2.48% as of March 31, 2022 and 1.85% at December 31, 2021.

In October 2018, the Company, through the acquisition of First American International Corp. (“FAIC”), acquired First American International Statutory Trust I (“FAIC Trust”), a Delaware statutory trust formed in December 2004. The FAIC Trust issued 7,000 units of thirty-year fixed to floating rate capital securities with an aggregate liquidation amount of $7,000,000 to an independent investor, and FAIC issued $7.2 million of subordinated debentures to the FAIC Trust for all of its common securities, amounting to $217,000, which is included in other assets. There was a $1.2 million valuation reserve recorded to arrive at market value which is treated as a yield adjustment and is amortized over the life of the security. The Company has the option to defer interest payments on the subordinated debentures from time to time for a period not to exceed five consecutive years. The subordinated debentures have a variable rate of interest equal to three-month LIBOR plus 2.25% through final maturity on December 15, 2034. The rate at March 31, 2022 was 3.08% and 2.45% at December 31, 2021.

In January 2020, the Company, through the acquisition of PGBH, acquired Pacific Global Bank Trust I (“PGBH Trust”), a Delaware statutory trust formed in December 2004. PGBH Trust issued 5,000 units of fixed to floating rate capital securities with an aggregate liquidation amount of $5,000,000 and 155 common securities with an aggregate liquidation amount of $155,000. PGBH issued $5.2 million of subordinated debentures to PGBH Trust in exchange for ownership of all the common securities of PGBH Trust. There was a $763,000 valuation reserve recorded to arrive at market value which is treated as a yield adjustment and is amortized over the life of the security. The Company has the option to defer interest payments on the subordinated debentures from time to time for a period not to exceed five consecutive years. The subordinated debentures have a variable rate of interest equal to three-month LIBOR plus 2.10% through final maturity on December 15, 2034. The rate at March 31, 2022 was 2.93% and 2.30% at December 31, 2021.

The Company paid interest expense of $100,000 and $95,000 for the three months ended March 31, 2022 and 2021, respectively, on the subordinated debentures. The amount of aggregate amortization expense recognized for the three months ended March 31, 2022 and 2021 was $55,000 and $55,000, respectively.

For regulatory reporting purposes, the Federal Reserve has indicated that the capital or trust preferred securities qualify as Tier 1 capital of the Company subject to previously specified limitations (including that the asset size of the issuer did not exceed $15 billion), until further notice. If regulators make a determination that the capital securities can no longer be considered in regulatory capital, the securities become callable and the Company may redeem them.

The British banking regulators eliminated the use of the LIBOR rate at the end of 2021. At this point in time, the Company has adopted SOFR as the alternative reference rate to replace LIBOR with respect to the Company’s subordinated debentures

Commitments Disclosure [Text Block]

NOTE 13 - COMMITMENTS

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. Those instruments involve to varying degrees, elements of credit and interest rate risk not recognized in the Company's financial statements.

The Company's exposure to loss in the event of nonperformance on these financial commitments is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments as it does for loans reflected in the financial statements.

At March 31, 2022 and December 31, 2021, the Company had the following financial commitments whose contractual amount represents credit risk:

	*March 31,*		*December 31,*
*(dollars in thousands)*	*2022*		*2021*
Commitments to make loans	$	202,537	$	202,288
Unused lines of credit		260,255		251,931
Commercial and similar letters of credit		3,001		1,214
Standby letters of credit		4,328		4,728
Total	$	470,121	$	460,161

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total amounts do not necessarily represent future cash requirements. The Company evaluates each client's credit worthiness on a case-by-case basis. The amount of collateral obtained if deemed necessary by the Company is based on management's credit evaluation of the customer.

The Company is involved in various matters of litigation which have arisen in the ordinary course of business and accruals for estimates of potential losses have been provided when necessary and appropriate under generally accepted accounting principles. In the opinion of management, the disposition of such pending litigation will not have a material effect on the Company's financial statements.

NOTE 14 - LEASES

On January 1, 2021, the Company adopted ASU 2016-02, Leases (Topic 842) and 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 Right-of-Use (“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. 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 March 31, 2022.

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 Company uses its incremental borrowing rate to determine the present value of its lease liabilities.

The Company leases several of its operating facilities under various non-cancellable operating leases expiring at various dates through 2036. The Company is also responsible for common area maintenance, taxes, and insurance at the various branch locations.

Future minimum rent payments on the Company’s leases were as follows at March 31, 2022:

*(dollars in thousands)*
As of March 31, 2022:
2022 remaining	$	3,484

Total present value of lease payments	$	23,314

The minimum rent payments shown above are given for the existing lease obligation and are not a forecast of future rental expense. Total rental expense, recognized on a straight-line basis, was $1.3 million and $1.3 million for the three months ended March 31, 2022 and 2021, respectively. The Company received rental income of $135,000 and $105,000 in the first quarter of 2022 and 2021, respectively.

NOTE 16 - STOCK-BASED COMPENSATION

RBB Bancorp 2010 Stock Option Plan

Under the RBB Bancorp 2010 Stock Option Plan (the “2010 Plan”), the Company was permitted to grant awards to eligible persons in the form of qualified and non-qualified stock options. The Company reserved up to 30% of the issued and outstanding shares of common stock as of the date the Company adopted the 2010 Plan or 3,494,478 shares, for issuance under the 2010 Plan. Following receipt of shareholder approval of the 2017 Omnibus Stock Incentive Plan (the “OSIP”) in May 2017, no additional grants were made under the 2010 Plan. The 2010 Plan has been terminated and options that were granted under the 2010 Plan have become subject to the OSIP. Awards that were granted under the 2010 Plan will remain exercisable pursuant to the terms and conditions set forth in individual award agreements, but such awards will be assumed and administered under the OSIP. The 2010 Plan award agreements allow for acceleration of exercise privileges of grants upon occurrence of a change in control of the Company. If a participant’s job is terminated for cause, then all unvested awards expire at the date of termination.

RBB Bancorp 2017 Omnibus Stock Incentive Plan

The OSIP was adopted by the Company’s board of directors in January 2017 and approved by the Company’s shareholders in May 2017. The OSIP was designed to ensure continued availability of equity awards that will assist the Company in attracting and retaining competent managerial personnel and rewarding key employees, directors and other service providers for high levels of performance. Pursuant to the OSIP, the Company’s board of directors are allowed to grant awards to eligible persons in the form of qualified and non-qualified stock options, restricted stock, restricted stock units, stock appreciation rights and other incentive awards. The Company has reserved up to 30% of issued and outstanding shares of common stock as of the date the Company adopted the OSIP, or 3,848,341 shares. As of March 31, 2022, there were 994,047 shares of common stock available for issuance under the OSIP. This represents 5.2% of the issued and outstanding shares of the Company’s common stock as of March 31, 2022. Awards vest, become exercisable and contain such other terms and conditions as determined by the board of directors and set forth in individual agreements with the employees receiving the awards. The OSIP enables the board of directors to set specific performance criteria that must be met before an award vests. The OSIP allows for acceleration of vesting and exercise privileges of grants if a participant’s termination of employment is due to a change in control, death or total disability. If a participant’s job is terminated for cause, then all awards expire at the date of termination.

The recorded compensation expense for stock options was $86,000 and $111,000 and the Company recognized income tax benefit of $23,000 and $56,000 for the three months ended March 31, 2022 and 2021, respectively. Unrecognized stock-based compensation expense related to options was $399,000 and $924,000 as of March 31, 2022 and 2021, respectively. Unrecognized stock-based compensation expense will be recognized over a weighted-average period of 1.4 years as of March 31, 2022.

There were no options granted during the first quarter of 2022. The fair value of prior option grants were estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions presented below for 2021 and 2020.

	July 2021			January 2021
Expected volatility		31.6	%		30.8	%
Expected term (years)	6.0 years			6.0 years
Expected dividends		1.98	%		1.86	%
Risk free rate		0.48	%		0.26	%
Grant date fair value	$	5.69		$	4.14

	July 2021			January 2021

Expected term (years)	6.0 years			6.0 years
Expected dividends		1.98	%		1.86	%
Risk free rate		0.48	%		0.26	%
Grant date fair value	$	5.69		$	4.14

The expected volatility was based on the historical volatility of the Company stock trading history. The expected term represents the estimated average period of time that the options remain outstanding. The expected term of options granted is based on historical data and represents the period of time that options granted are expected to be outstanding. The risk free rate of return reflects the grant date interest rate offered for zero coupon U.S. Treasury bonds over the expected term of the options.

A summary of the status of option awards pursuant to the Company's stock option plans as of March 31, 2022 and changes during the three months ended is presented below:

These restricted stock units are scheduled to vest over a two year period for shares granted to directors and a three year period for shares granted to executive officers from the January 19, 2022 grant date. As of March 31, 2022. there were 38,807 remaining unvested restricted stock units.

The recorded compensation expense for restricted stock units was $83,000 and none for the three months ended March 31, 2022 and 2021, respectively. Unrecognized stock-based compensation expense related to restricted stock unit was $971,000 and zero as of March 31, 2022 and 2021, respectively. As of March 31, 2022, unrecognized stock-based compensation expense related to restricted stock units is expected to be recognized over the next 2.5 years.

Regulatory Capital Requirements under Banking Regulations [Text Block]

NOTE 17 - REGULATORY MATTERS

Holding companies (with assets over $3 billion at the beginning of the year) and banks are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory - and possibly additional discretionary - actions by regulators that, if undertaken, could have a direct material effect on the Company’s financial statements.

In July 2013, the federal bank regulatory agencies approved the final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks. The new rules became effective on January 1, 2015, with certain of the requirements phased-in over a multi-year schedule. Under the rules, minimum requirements increased for both the quantity and quality of capital held by the Bank. The rules include a common equity Tier 1 (“CET1”) capital to risk-weighted assets ratio with minimums for capital adequacy and prompt corrective action purposes of 4.5% and 6.5%, respectively. The minimum Tier 1 capital to risk-weighted assets ratio was raised from 4.0% to 6.0% under the capital adequacy framework and from 6.0% to 8.0% to be well-capitalized under the prompt corrective action framework. In addition, the rules introduced the concept of a "conservation buffer" of 2.5% applicable to the three capital adequacy risk-weighted asset ratios (CET1, Tier 1, and Total). The implementation of the capital conservation buffer began on January 1, 2016 at 0.625% and was phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reached 2.5% on January 1, 2019). If the capital adequacy minimum ratios plus the phased-in conservation buffer amount exceed actual risk-weighted capital ratios, then dividends, share buybacks, and discretionary bonuses to executives could be limited in amount.

Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1 and CET1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined). As permitted by the regulators for financial institutions that are not deemed to be “advanced approaches” institutions, the Company has elected to opt out of the Basel III requirement to include accumulated other comprehensive income in risk-based capital. Management believes that at March 31, 2022 and December 31, 2021, RBB and the Bank satisfied all capital adequacy requirements to which they were subject.

As defined in applicable regulations and set forth in the tables below, RBB and the Bank continue to exceed the regulatory capital minimum requirements and the Bank continues to exceed the "well capitalized" standards at the dates indicated:

The California Financial Code generally acts to prohibit banks from making a cash distribution to its shareholders in excess of the lesser of the bank's undivided profits or the bank's net income for its last three fiscal years less the amount of any distribution made by the bank's shareholders during the same period.

The California General Corporation Law generally acts to prohibit companies from paying dividends on common stock unless retained earnings, immediately prior to the dividend payment, equals or exceeds the amount of the dividend. If a company fails this test, then it may still pay dividends if after giving effect to the dividend the company's assets are at least 125% of its liabilities.

Additionally, the Federal Reserve has issued guidance which requires that they be consulted before payment of a dividend if a financial holding company does not have earnings over the prior four quarters of at least equal to the dividend to be paid, plus other holding company obligations.

Fair Value Measurement and Measurement Inputs, Recurring and Nonrecurring [Text Block]

NOTE 18 - FAIR VALUE MEASUREMENTS

The following is a description of valuation methodologies used for assets and liabilities recorded at fair value:

Securities: The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1) or matrix pricing, which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted prices for specific securities but rather by relying on the securities' relationship to other benchmark quoted securities (Level 2).

Other Real Estate Owned: Nonrecurring adjustments to certain commercial and residential real estate properties

classified as other real estate owned (“OREO”) are measured at the lower of carrying amount or fair value, less costs to sell. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized. Fair values are generally based on third party appraisals of the property which are commonly adjusted by management to reflect an expectation of the amount to be ultimately collected and selling costs (Level 3).

Appraisals for OREO are performed by state licensed appraisers (for commercial properties) or state certified appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. When a Notice of Default is recorded, an appraisal report is ordered. Once received, a member of the credit administration department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison to independent data sources such as recent market data or industry wide-statistics for residential appraisals. Commercial appraisals are sent to an independent third party to review. The Company also compares the actual selling price of collateral that has been sold to the most recent appraised value to determine what additional adjustments, if any, should be made to the appraisal values on any remaining other real estate owned to arrive at fair value. If the existing appraisal is older than twelve months a new appraisal report is ordered. No significant adjustments to appraised values have been made as a result of this comparison process as of March 31, 2022.

Interest Rate Lock Contracts and Forward Mortgage Loan Sale Contracts: The fair values of interest rate lock contracts and forward mortgage loan sale contracts are determined by loan lock-in rate, loan funded rate, market interest rate, fees to be collected from the borrower, fees and costs associated with the origination of the loan, expiration timing, sale price, and the value of the retained servicing. The company classified these derivatives as level 3 due to management’s estimate of market rate, cost and expiration timing on these contracts.

Collateral-dependent impaired loans: Collateral-dependent impaired loans are carried at fair value when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the original loan agreement and the loan has been written down to the fair value of its underlying collateral, net of expected disposition costs where applicable. Collateral-dependent impaired loans evaluated with specific reserves are classified as Level 3 assets. There were no loans of this type as of March 31, 2022 and December 31, 2021.

The following table provides the hierarchy and fair value for each major category of assets and liabilities measured at fair value at March 31, 2022 and December 31, 2021:

No write-downs to OREO were recorded for the three months ended March 31, 2022 or for the year ended December 31, 2021.

Quantitative information about the Company's recurring Level 3 fair value measurements as of March 31, 2022 and December 31, 2021 is as follows:

At December 31, 2021, fair value for IRLCs and FMLSCs totaled $265,000. All IRLCs and FMLSCs at December 31, 2021 were funded and sold to Fannie Mae in the first three months of 2022. Changes in fair value were $233,000 in 2022. Fair value for IRLCs and FMLSCs totaled $32,000 at March 31, 2022.

The fair value measurement of IRLCs and FMLSCs were primarily based on the buy price from borrowers ranging from 97 to 100, the sale price to Fannie Mae ranging from 98 to 103, and the significant unobservable inputs using margin cost rate of 1.50%.

Quantitative information about the Company's OREO non-recurring Level 3 fair value measurements at March 31, 2022 and December 31, 2021 is as follows:

OREO consists of one single-family residence with a fair value of $293,000 as of March 31, 2022 and December 31, 2021. OREO was evaluated by third party appraisals with unobservable input of management adjustment in the range of 5%-6% to reflect current conditions and selling costs.

Interest Rate Lock Commitments ("IRLCs"): 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.

The FASB Accounting Standards Codification (“FASB ASC”) 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 (if material). FASB ASC Topic 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. Consequently, the Company has elected to account for these obligations at fair value.

Forward Mortgage Loan Sale Contracts ("FMLSCs"): 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. They 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.

Mandatory delivery commitments, also known as forward loan sales commitments, are considered to be derivatives under FASB 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)

●

They have a notional amount (the committed loan principal amount)

●

They require little or no initial net investment

●

They require or permit net settlement as the institution via a pair-off transaction or the payment of a pair-off fee.

Fair Value Disclosures [Text Block]

NOTE 19 - FAIR VALUE OF FINANCIAL INSTRUMENTS

The fair value of a financial instrument is the amount at which the asset or obligation could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the entire holdings of a particular financial instrument. Because no market value exists for a significant portion of the financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, involve uncertainties and matters of judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on financial instruments both on and off the balance sheet without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Additionally, tax consequences related to the realization of the unrealized gains and losses can have a potential effect on fair value estimates and have not been considered in many of the estimates.

In accordance with accounting guidance, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, volatilities, etc.) or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market.

Level 3 - Valuation is generated from model-based techniques where one or more significant inputs are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models, and similar techniques.

Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates.

The Company uses the following methods and assumptions to estimate the fair value of each class of financial instruments:

For cash and due from banks, Federal funds sold, and cash equivalents, the carrying amount is assumed to be a reasonable estimate of fair value, a Level 1 measurement.

For short-term investments and interest-bearing deposits, the carrying amount is assumed to be a reasonable estimate of fair value, a Level 1 measurement.

Securities available for sale and held-to-maturity are measured by using quoted market prices for similar securities or dealer quotes, a Level 2 measurement. This category generally includes U.S. Government agency securities, U.S. Government sponsored entities, state and municipal securities, mortgage backed securities (“MBS”), collateralized mortgage obligations and corporate bonds.

Equity securities fair value are measured based on unobservable inputs at the reporting date, a Level 3 measurement. Equity securities are comprised of affordable housing investment funds and other restricted stocks.

Fair values are estimated for portfolios of loans with similar financial characteristics. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and non-performing categories. The fair values are based primarily on third-party vendor pricing to determine fair values based on the exit price notion.

The fair value of performing loans is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan, a Level 3 measurement.

The fair value of impaired loans is calculated based on the net realizable fair value of the collateral or the observable market price of the most recent sale or quoted price from loans held for sale. The Company does not record loans at fair value on a recurring basis. Nonrecurring fair value adjustments to collateral dependent impaired loans are recorded based on the adjusted appraised value of the collateral, a Level 3 measurement.

The Company records loans held for sale at fair value based on quoted prices from third party sale analysis, existing sale agreements, or appraisal reports adjusted by sales commission assumption, a Level 1 measurement.

Mortgage and SBA servicing rights are calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan, a Level 2 measurement.

The fair value of demand deposits, savings accounts, and certain money market deposits is assumed to be the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using the rates currently offered for deposits with similar remaining maturities, a Level 2 measurement.

The fair value of commitments to extend credit and standby letters of credit, interest rate lock commitments and forward mortgage loan sales contracts is estimated using the fees currently charged to enter into similar agreements. Unobservable inputs that reflect the Company's own assumptions about the assumptions that market participants would use in pricing an asset or liability result in a Level 3 measurement.

The fair value of FHLB advances is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk, a Level 3 measurement.

Subordinated debentures fair value is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk, a Level 3 measurement.

The fair value of long-term debt is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk, a Level 3 measurement.

Fair value is estimated in accordance with ASC Topic 825. Fair value estimates are made at specific points in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Bank’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

The fair value hierarchy level and estimated fair value of significant financial instruments at March 31, 2022 and December 31, 2021 are summarized as follows:

Significant Accounting Policies (Policies)	3 Months Ended
Significant Accounting Policies (Policies)	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The accompanying unaudited 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-Q 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 interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results for the full year. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2021, included in our Annual Report filed on Form 10-K for the fiscal year ended December 31, 2021 and Amendment No. 1 to the Annual Report on Form 10-K/A (collectively our “2021 Annual Report”).
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 our estimate of the allowance for loan losses and the fair value of mortgage servicing rights could change as actual results could differ from those estimates. Actual results could differ from those estimates.
Summary of Significant Accounting Policies [Policy Text Block]	Summary of Significant Accounting Policies The accompanying unaudited consolidated financial statements were compiled in accordance with the accounting policies set forth in Note 2 – Basis of Presentation and Summary of Significant Policies in our Consolidated Financial Statements as of and for the year ended December 31, 2021, included in our 2021 Annual Report. The Financial Accounting Standards Board ("FASB") issues Accounting Standards Updates ("ASU" or “Update”) and Accounting Standards Codifications (“ASC”), which are the primary source of GAAP.
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements When RBB conducted its initial public offering (“IPO”) in 2017, we qualified as an emerging growth company (“EGC”). We will remain an EGC until the earliest of (i) the end of the fiscal year during which we have total annual gross revenues of $1.0 billion or more, (ii) the end of the fiscal year following the fifth anniversary of the completion of our IPO, (iii) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt and (iv) the date on which we are deemed to be a “large accelerated filer” under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We anticipate no longer qualifying as an EGC on December 31, 2022. EGCs are entitled to reduced regulatory and reporting requirements under the Securities Act of 1933, as amended (the “Securities Act”), and the Exchange Act, as compared to public business entities ("PBE"). In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The most significant change for lessees is the requirement under the new guidance to recognize right-of-use assets and lease liabilities for all leases not considered short-term leases, which is generally defined as a lease term of less than 12 months. This change will result in lessees recognizing right-of-use assets and lease liabilities for most leases currently accounted for as operating leases under current lease accounting guidance. Under the new guidance, the Company recognized on the Consolidated Balance Sheets right-of-use assets with a corresponding lease liability. The Company early adopted this ASU on January 1, 2021 and recorded the right-of-use asset and lease liability of approximately $26.8 million. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instrument (Topic 326), including subsequent amending ASUs. This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The standard will replace today's "incurred loss" approach with an "expected loss" model. The new model, referred to as the current expected credit loss ("CECL") model, will apply 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, entities will measure credit losses in a manner similar to what they do today, except that the 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 loan and lease losses. In addition, public business entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU 2016-13 was originally proposed to be effective for interim and annual reporting periods for an emerging growth company beginning after December 15, 2020, but was subsequently extended until December 31, 2022. Entities will apply the standard's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company has begun its evaluation of the impact of the implementation of ASU 2016-13. The implementation of the provisions of ASU 2016-13 will most likely impact the Company’s consolidated financial statements as to the level of reserves that will be required for credit losses. The Company will continue to assess the potential impact that this Update will have on the Company’s consolidated financial statements. The Company will adopt CECL (ASU 2016-13) on December 31, 2022. 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 provides banking organizations 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 will have the option to gradually phase in the full effect of CECL on regulatory capital over a five-year transition period. At this point, RBB does not expect to take the option to phase in effect of CECL. 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.” For PBE's, ASU 2017-04 is effective for annual and any interim impairment tests performed in periods beginning after December 15, 2019. As an EGC, the Company will adopt this ASU on December 31, 2022. Adoption of ASU 2017-04 is not expected to have a significant impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This Update provides additional guidance to ASU 2015-05, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement” (CCA), on the accounting for implementation, setup, and other upfront costs (collectively referred to as implementation costs) apply to entities that are a customer in a hosting arrangement. This Update applies to entities that are a customer in a hosting arrangement that is a service contract. Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. This Update also requires the customer to expense the capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement. This Update is effective for an EGC for annual reporting periods beginning after December 15, 2020, and interim periods within annual periods beginning after December 15, 2021. Early adoption of the amendments in this Update is permitted, including adoption in any interim period, for all entities. The amendments in this Update should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. This Update will most likely not have a material impact unless the Company incurs implementation costs for a CCA that is a service contract. In January 2020, the FASB issued ASU 2020-01, “Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)”. This ASU is for equity securities accounted for by the equity method. The amendment clarifies that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The Company has equity securities on our balance sheet but are not material to be considered for the equity method. For an EGC, this ASU is effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. The Company adopted this ASU on January 1, 2022 and this ASU did not have a material 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. As an EGC, the Company will implement CECL on December 31, 2022. 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 (generally through December 31, 2022). For contract modifications, companies can account for the modification as a continuation of the existing contract without additional analysis. For held-to-maturity (“HTM”) debt securities, one-time sale and/or transfer to available-for-sale or trading may be made for HTM debt securities that both reference an eligible reference rate and were classified as HTM before January 1, 2020. Regarding the effective date and transition: (1) companies can apply the ASU as of the beginning of the interim period that includes March 12, 2020 (e.g. January 1, 2020 for calendar year-end companies) or any date thereafter, (2) the ASU applies prospectively to contract modifications and hedging relationships, and (3) the one-time election to sell and/or transfer debt securities classified as HTM may be made at any time after March 12, 2020. 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. Of the Company’s $3.0 billion in total gross loans as of March 31, 2022, approximately 6.8% have a LIBOR based reference rate. 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 Form 10-Q. The Company is developing new SOFR-based loan products that will be equivalent to prior LIBOR-based loan products. We anticipate a neutral financial impact. 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 ASU is potentially material to the Company, depending on the materiality of an acquired contract asset or liability. The Update is effective for public companies in fiscal years starting after December 15, 2022. Early adoption is permitted. This ASU will be effective for the Company on January 1, 2023. In November 2021, the FASB issued ASU 2021-10 "Disclosures by Business Entities about Government Assistance". The amendments in this Update require the annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. This Update is applicable to the Company and was adopted January 1, 2022. In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. This pronouncement eliminates the accounting guidance on troubled debt restructurings ("TDRs") for creditors and amends the guidance on “vintage disclosures” to require disclosure of current-period gross write-offs by year of origination. The ASU also updates the requirements related to accounting for credit losses under ASC 326 and adds enhanced disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty. As the Company will adopt ASU 2016-13 (“CECL”) on December 31, 2022, ASU 2022-02 will also be effective for the Company on December 31, 2022.
