Management has established various accounting policies that govern the application of generally accepted accounting principles in the U.S. (“GAAP”) in the preparation of our financial statements. Certain accounting policies require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates under different assumptions or conditions.

Allowance for Credit Losses

A sensitivity analysis of our ACL was performed as of March 31, 2024. Based on this sensitivity analysis, a positive 25% change in prepayment speed would result in a $961,000, or (2.32)%, decrease to the ACL. A negative 25% change in prepayment speed would result in a $1.27 million, or 3.08%, increase to the ACL. Additionally, a one percentage point increase in the unemployment rate would result in a $742,000, or 1.80%, increase to the ACL and a one percentage point decrease in the unemployment rate would result in a $675,000, or (1.63)%, decrease to the ACL. Management reviews the results using the comparison scenario for sensitivity analysis and considered the results when evaluating the qualitative factor adjustments.

On a quarterly basis, we stress test the qualitative factors, which are lending policy, procedures and strategies, economic conditions, changes in nature and volume of the portfolio, credit and lending staff, problem loan trends, loan review results, collateral value, concentrations and regulatory and business environment by creating two scenarios, moderate risk and major risk. In the Moderate Stress scenario, the status of all nine risk factors across all pooled loan segments were set at “Moderate Risk” while in the Major Stress scenario, the status of all nine risk factors across all pooled loan segments were set at “Major Risk.” Under the Moderate Stress scenario, the ACL would increase by $3.8 million, or 9.20%, as of March 31, 2024. Under the Major Stress scenario, the ACL would increase by $19.0 million, or 46.01%, as of March 31, 2024.

For additional information on the policies, methodologies and judgments used to determine the ACL, see Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies in our Annual Report filed on Form 10-K for the fiscal year ended December 31, 2023 ("2023 Annual Report"), and Note 4 — Loans and Allowance for Credit Losses to the Notes to Consolidated Financial Statements in this Form 10-Q.

Our significant accounting policies are described in greater detail in our audited consolidated financial statements included in our 2023 Annual Report, which are essential to understanding Management’s Discussion and Analysis of Financial Condition and Results of Operations.

GENERAL

RBB is a bank 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, the Bank and RBB Asset Management Company (“RAM”). RAM was formed to hold and manage problem assets acquired in business combinations. When we refer to “we”, “us”, “our”, or the “Company”, we are referring to RBB Bancorp and its consolidated subsidiaries including the Bank, collectively. When we refer to the “parent company”, “Bancorp”, or the “holding company”, we are referring to RBB Bancorp, the parent company, on a stand-along basis. At March 31, 2024, we had total assets of $3.9 billion, gross loans of $3.0 billion, total deposits of $3.0 billion and total shareholders' equity of $514.0 million. RBB’s common stock trades on the Nasdaq Global Select Market under the symbol “RBB.”

The Bank provides business-banking products and services predominantly to the Asian-American communities through full service branches located in Los Angeles County, Orange County and Ventura County in California, in the Las Vegas, Nevada and New York City metropolitan areas, Chicago (Illinois), Edison (New Jersey) and Honolulu (Hawaii). The products and services include 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, including specialized services such as remote deposit, E-banking, and mobile banking.

We operate as a minority depository institution, which is defined by the FDIC as a federally insured depository institution where 51% or more of the voting stock is owned by minority individuals or a majority of the board of directors is minority and the community that the institution serves is predominantly minority. A minority depository institution is eligible to receive from the FDIC and other federal regulatory agencies training, technical assistance and review, and assistance regarding the implementation of proposed new deposit taking and lending programs, as well as with respect to the adoption of applicable policies and procedures governing such programs. We intend to maintain our minority depository institution designation, as it is expected that at least 51% of our issued and outstanding shares of capital shall remain owned by minority individuals. The minority depository institution designation has been historically beneficial to us, as the FDIC has reviewed and assisted with the implementation of our deposit and lending programs, and we continue to use the program for technical assistance.

We operate 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. Our primary source of revenue is providing loans to customers, who are predominately small and middle-market businesses and individuals.

We have completed six whole bank acquisitions and one branch acquisition from July 2011 through January 2022. All of our 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.
