NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of RBB Bancorp and its wholly-owned subsidiaries Royal Business Bank (Bank) and RBB Asset Management Company (RAM), collectively referred to herein as "the Company", “we”, “our” or “us”.  All significant intercompany accounts and transactions have been eliminated in consolidation.  RBB Bancorp has no significant business activity other than its investments in Royal Business Bank and RAM.  

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. That, in the opinion of management, are necessary to reflect a fair presentation of financial results for the interim periods presented. The results of operations for the three months ended March 31, 2018 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 included in our Annual Report on Form 10-K for the year ended December 31, 2017 (the “2017 Annual Report”).

The Company accounts for its investments in its wholly owned special purpose TFC Statutory Trust under the equity method whereby the subsidiary's net earnings are recognized in the Company's statement of income.

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.  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 – Summary of Significant Policies in our consolidated financial statements included in our 2017 Annual Report.  

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606).  This Update requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services.  The following steps are applied in the updated guidance: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation.  These amendments are effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and one year later for nonpublic business entities.  Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that period. The Company plans to adopt ASU 2014-09 on January 1, 2019 utilizing the modified retrospective approach.  Since the guidance does not apply to revenue associated with financial instruments such as loans and investments, which are accounted for under other provisions of GAAP, we do not expect it to impact interest income, our largest component of income.  The Company will perform an overall assessment of revenue streams potentially affected by the ASU, including certain deposit related fees and interchange fees, to determine the impact this guidance will have on our consolidated financial statements.

RBB BANCORP AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (UNAUDITED)

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10).  Changes made to the current measurement model primarily affect the accounting for equity securities and readily determinable fair values, where changes in fair value will impact earnings instead of other comprehensive income.  The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged.  The Update also changes the presentation and disclosure requirements for financial instruments including a requirement that public business entities use exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes.  This Update is generally effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years and one year later for nonpublic business entities.  Based upon an evaluation of the guidance in ASU 2016-01 the Company determined the ASU will not have a material impact on the Company’s consolidated financial statements as the accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged.  The Company adopted this ASU as of January 1, 2018 but will continue to monitor any updates to the guidance.  

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.  The amendments in this Update are effective for interim and annual periods beginning after December 15, 2018, for public business entities and one year later for all other entities.  The Company has several lease agreements which are currently considered operating leases and are therefore not included on the Company’s Consolidated Balance Sheets.  Under the new guidance the Company expects that some of the lease agreements will have to be recognized on the Consolidated Balance Sheets as a right-of-use asset with a corresponding lease liability.  Based upon a preliminary evaluation the Company expects that the ASU will have an impact on the Company’s Consolidated Balance Sheets.  The Company will continue to evaluate how extensive the impact will be under the ASU on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718.)  ASU 2016-09 includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements.  Under ASU 2016-09, excess tax benefits and certain tax deficiencies will no longer be recorded in additional paid-in capital (APIC).  Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement, and APIC pools will be eliminated.  In addition, the guidance requires excess tax benefits be presented as an operating activity on the statement of cash flows rather than as a financing activity.  ASU 2016-09 also permits an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards.  Forfeitures can be estimated, as required today, or recognized when they occur.  This guidance is effective for public business entities for interim and annual reporting periods beginning after December 15, 2016, and for nonpublic business entities annual reporting periods beginning after December 15, 2017, and interim periods within the reporting periods beginning after December 15, 2018.  Early adoption is permitted, but all of the guidance must be adopted in the same period.  The Company early adopted the ASU as of January 1, 2017. The Company plans to recognize forfeitures as they occur.  The early adoption of the ASU did not have a material effect on the company’s financial statements or disclosures.  

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instrument (Topic 326).  This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren't measured at fair value through net income.  In issuing the standard, the FASB is responding to criticism that today's guidance delays recognition of credit losses.  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.  The CECL model does not apply to available for sale (AFS) debt securities.  For 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.  As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today.  The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans.  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 No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019, for SEC filers, one year later for non SEC filing public business entities and annual reporting periods beginning after December 15, 2020, for nonpublic business entities and interim periods within the reporting periods beginning after December 15, 2021.  Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018.  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 No. 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 access the potential impact that this ASU will have on the Company’s consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (UNAUDITED)

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Topic 230). The new guidance clarifies the classification within the statement of cash flows for certain transactions, including debt extinguishment costs, zero-coupon debt, contingent consideration related to business combinations, insurance proceeds, equity method distributions and beneficial interests in securitizations. The guidance also clarifies that cash flows with aspects of multiple classes of cash flows that cannot be separated by source or use should be classified based on the activity that is likely to be the predominant source or use of cash flows for the item. This guidance is effective for fiscal years beginning after December 15, 2017 and will require application using a retrospective transition method. The Company adopted this statement as of January 1, 2018.  The Company believes the requirement to separately identify cash flows and application of the predominance principle is the cash flow item currently applicable to the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business (Topic 805). Currently, the ASU specifies three elements of a business – inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs, for example, by integrating the acquired set with their own inputs and processes. This led many transactions to be accounted for as business combinations rather than asset purchases under legacy GAAP. The primary goal of ASU 2017-01 is to narrow the definition of a business, and the guidance in this update provides a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this update should be applied prospectively on or after the effective date. The Company adopted this ASU on January 1, 2018 and will be applied prospectively for any future business combinations.

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350).  This ASU 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 the ASU, “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.”  ASU No. 2017-14 is effective for annual and any interim impairment tests performed in periods beginning after December 15, 2019 for public business entities that are SEC filers, December 15, 2020 for business entities that are not SEC filers, and December 15, 2021 for all other entities.  Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.   The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities (Subtopic 310-20), which is intended to enhance “the accounting for the amortization of premiums for purchased callable debt securities.” The ASU shortens the amortization period for certain callable debt securities purchased at a premium by requiring that the premium be amortized to the earliest call date. Under GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument.  The amendments in this Update affects all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The ASU’s amendments are effective for public business entities for interim and annual periods beginning after December 15, 2018. For other entities, the amendments are effective for annual periods beginning after December 15, 2019, and interim periods thereafter. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle.The implementation of the provisions of ASU No. 2017-08 will most likely not have a material impact the Company’s consolidated financial statements.The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation: Scope of codification Accounting (Topic 718). The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share- entity to apply modification accounting. An entity should account for the effects of a modification unless all the following are met: (1) The fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (UNAUDITED)

value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in ASU No. 2017-09 are effective for annual periods, and interim within those annual reporting periods, beginning after December 15, 2017; early adoption is permitted. The amendments in this ASU should be applied prospectively to an award modified on or after the adoption date. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements.

In July 2017, the FASB issued ASU 2017-13—Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments  (SEC Update).  At the July 20, 2017, EITF meeting, the SEC staff announced that it would not object when certain public business entities (PBEs) elect to use the non-PBE effective dates solely to adopt the FASB’s new standards on revenue (ASC 606) and leases (ASC 842). This ASU reflects comments made by the SEC. The Company will continue to evaluate how extensive the impact will be under the ASU on the Company’s consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02 – Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this Update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.  The amendments in this Update also require certain disclosures about stranded tax effects.  The amendments in this Update are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years.  Early adoption of the amendments in this Update is permitted, including adoption in any interim period, (1) for public business entities for reporting periods for which financial statements have not yet been issued and (2) for all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this Update should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized.  The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

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 at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation.  For securities in an unrealized loss position, management 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.

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES

The Company's loan portfolio consists primarily of loans to borrowers within Los Angeles, Ventura and Orange counties in California and Las Vegas (Clark County) in Nevada.  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 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.

16

RBB BANCORP AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (UNAUDITED)

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 (TDRs) are considered impaired.  

The risk category of loans by class of loans was as follows at March 31, 2018 and December 31, 2017:

No interest income was recognized on a cash basis for the three months ended March 31, 2018 and for the year ended December 31, 2017.  

The Company had five and four loans identified as TDRs at March 31, 2018 and December 31, 2017, respectively.  There were no specific reserves on TDRs as of March 31, 2018 or December 31, 2017.  There are no commitments to lend additional amounts at March 31, 2018 and December 31, 2017 to customers with outstanding loans that are classified as TDRs.

As of March 31, 2018, the terms of one loan was modified as TDR.  The modification of the terms generally included loans wherea moratorium on loan payments was granted.  Suchmoratoriums ranged from three months to twelve monthson the loans restructured in 2017 and 2016.

NOTE 4 - LOAN SERVICING

When mortgage and Small Business Administration (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.

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.

The principal balances of mortgage and SBA loans serviced for others at March 31, 2018 and December 31, 2017 are as follows:

Servicing fees net of servicing asset amortization totaled $(31,000) and $262,000 for the three months ended March 31, 2018 and 2017, respectively.

NOTE 5 - GOODWILL AND INTANGIBLES

Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date.  Goodwill resulting from whole bank acquisitions is not amortized, but tested for impairment at least annually.  The Company has selected December 31^st as the date to perform the annual impairment test.  Goodwill amounted to $29.9 million at March 31, 2018 and December 31, 2017, and is the only intangible asset with an indefinite life on the balance sheet.  There were no impairment losses recognized on goodwill during the three months ended March 31, 2018 and 2017.

Other intangible assets consist of core deposit intangible ("CDI") assets arising from whole bank acquisitions.   CDI assets are amortized on an accelerated method over their estimated useful life of 8 to 10 years.  CDI was recognized in the 2013 acquisition of Los Angeles National Bank and in the 2016 acquisition of TFC Holding Company.  The unamortized balance at March 31, 2018 and December 31, 2017 was $1,357,000 and $1,438,000, respectively, for both Los Angeles National Bank and TFC Holding Company.  CDI amortization expense was $81,000 and $94,000 for the three months ended March 31, 2018 and March 31, 2017, respectively, for both Los Angeles National Bank and TFC Holding Company.

Estimated CDI amortization expense for future years is as follows (dollars in thousands):

NOTE 7 - LONG-TERM DEBT

In March 2016, the Company issued $50 million of 6.5% fixed to floating rate subordinated debentures, due March 31, 2026. The interest rate is fixed through March 31, 2021 and floats at 3 month London Interbank Offered Rate (LIBOR) plus 516 basis points thereafter. The subordinated debt is considered Tier-2 capital at the Company. The Company allocated $35 million to the Bank as Tier-1 capital.

At March 31, 2018 and December 31, 2017 the aggregate outstanding principal amount and unamortized debt issuance costs related to these subordinated debentures were as follows:

NOTE 8 - SUBORDINATED DEBENTURES

The Company, through the acquisition of TFC Bancorp, acquired TFC Statutory Trust (Trust).  The Trust contained a pooled private offering of 5,000 Trust preferred securities with a liquidation amount of $1,000 per security. TFC Bancorp issued $5,000,000 of subordinated debentures to the Trust in exchange for ownership of all of the common security 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 $3,255,000. There was a $1,900,000 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 amount of amortization expense recognized for the three months ended March 31, 2018 and 2017 was constant at $23,000.   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 Bank 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 1 capital (with certain limitations applicable) under current regulatory guidelines and interpretations. The subordinated debentures have a variable rate of interest equal to the three month LIBOR plus 1.65%, which was 3.77% and 3.24% at March 31, 2018 and December 31, 2017, respectively.

NOTE 9 - BORROWING ARRANGEMENTS

The Company has established secured and unsecured lines of credit.  The Company may borrow funds from time to time on a term or overnight basis from the Federal Home Loan Bank of San Francisco (FHLB), the Federal Reserve Bank of San Francisco ("FRB") and other financial institutions as indicated below.

Federal Funds Arrangements with Commercial Banks.  At March 31, 2018, the Company may borrow on an unsecured basis, up to $20.0 million, $10.0 million, $12.0 million and $5.0 million overnight from Zions Bank, Wells Fargo Bank, First Tennessee National Bank, and Pacific Coast Bankers' Bank, respectively.

Letter of Credit Arrangements.  At March 31, 2018, the Company had an unsecured commercial letter of credit line with Wells Fargo Bank for $2.0 million.

FRB Secured Line of Credit.  The secured borrowing capacity of $13.8 million at March 31, 2018 is collateralized by loans pledged with a carrying value of $25.2 million.

FHLB Secured Line of Credit.  The secured borrowing capacity of $342.9 million at March 31, 2018 is collateralized by loans pledged with a carrying value of $392.2 million.

There were no amounts outstanding under any of the arrangements above at March 31, 2018. At December 31, 2017, the Company had $25.0 million in short-term borrowings with the FHLB at 1.41% which was repaid on January 2, 2018.  

NOTE 10 - INCOME TAXES

The asset and liability method is used in accounting for income taxes.  Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

During the three months ended March 31, 2018 and 2017, the Company recorded an income tax provision of $1.6 million and $3.9 million, respectively, reflecting and effective tax rate of 15.2% and 41.4% for the three months ended March 31, 2018 and 2017, respectively.

NOTE 11 - COMMITMENTS

The Company leases several of its operating facilities under various noncancellable operating leases expiring at various dates through 2028.  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, 2018:

(dollars in thousands)
Year ending December 31:
2018 remaining	$	1,338
2019		1,625
2020		1,396
2021		1,312
2022		1,089
Thereafter		4,117
	$	10,877

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 $437,000 and $381,000 for the three months ended March 31, 2018 and 2017, respectively.

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 loan 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, 2018 and December 31, 2017, the Company had the following financial commitments whose contractual amount represents credit risk:

	March 31,		December 31,
(dollars in thousands)	2018		2017
Commitments to make loans	$	103,354	$	101,960
Unused lines of credit		119,964		99,217
Commercial and similar letters of credit		4,700		3,013
Standby letters of credit		1,575		1,575
	$	229,593	$	205,765

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 GAAP.  In the opinion of management, the disposition of such pending litigation will not have a material effect on the Company's financial statements.

NOTE 13 - STOCK-BASED COMPENSATION

RBB Bancorp 2017 Omnibus Stock Incentive Plan.

The 2017 Omnibus Stock Incentive Plan, or OSIP, was adopted by the Company’s board of directors on January 18, 2017 and approved by the Company’s shareholders at the Company’s annual meeting on May 23, 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 2017 OSIP, or 3,848,341 shares. This represents 24% of the issued and outstanding shares of the Company’s common stock as of March 31, 2018.  As of March 31, 2018, there were 1,353,207 shares of common stock available for issuance under the OSIP. 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.

RBB Bancorp 2010 Stock Option Plan

Under 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. After approval of the OSIP at the Company’s annual meeting on May 23, 2017, no additional grants will be made under the 2010 Plan.  The 2010 Plan has terminated and options that were granted under that 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.

The Company recognized stock-based compensation expense of $131,000 and recognized income tax benefits on that expense of $1.2 million for the three months ended March 31, 2018.  The Company recognized stock-based compensation expense of $198,000 and recognized income tax benefits on that expense of $61,000 for the three months ended March 31, 2017.

NOTE 14 - REGULATORY MATTERS

Holding companies (with assets over $1 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (UNAUDITED)

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 new 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 will be phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 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 to risk-weighted assets, and of Tier 1 capital  to average assets.  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, at March 31, 2018 and December 31, 2017, that the Bank meets all capital adequacy requirements to which it is subject.

As defined in applicable regulations and set forth in the tables below, the Company 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 its 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 Bank has issued guidance which requires that they be consulted before payment of a dividend if a bank 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.

NOTE 15 - 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 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 other real estate owned 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, 2018.

The following table provides the hierarchy and fair value for each major category of assets and liabilities measured at fair value at March 31, 2018 and December 31, 2017:

NOTE 16 - 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.

Fair value measurement and disclosure standards also establish a framework for measuring fair values. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Further, the standards establish a fair value hierarchy that encourages an entity to maximize the use of observable inputs and limit the use of unobservable inputs when measuring fair values. The standards describe three levels of inputs that may be used to measure fair values:

•Level 1:  Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

•Level 2: Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data.

•Level 3: Significant unobservable inputs that reflect a company's own assumptions about the factors that market participants would likely consider in pricing an asset or liability.

Fair value estimates are made at a specific point in time based on relevant market data and information about the financial instruments. The estimates incorporate our assumptions with regard to the impact of prepayments on future cash flows and credit quality adjustments based on risk characteristics of various financial instruments, among other things. The estimates are subjective and involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly alter the fair values presented.

GENERAL

RBB Bancorp is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. Our principal business is to serve as the holding company for the Bank and RAM. At March 31, 2018, the Company had total assets of $1.7 billion, gross loans of $1.2 billion, total deposits of $1.3 billion and total stockholders' equity of $260.3 million. On July 31, 2017, the Company completed its initial public offering of 3,750,000 shares at a price to the public of $23.00 per share. The Company’s 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, Ventura County (California) and in Las Vegas (Clark County, Nevada), including remote deposit, E-banking, mobile banking, commercial and investor real estate loans, business loans and lines of credit, SBA 7A and 504 loans, mortgage loans, trade finance and a full range of depository accounts. RAM was formed to hold and manage problem assets acquired in business combinations.

The Company operates full-service banking offices in Arcadia, Cerritos, Diamond Bar, Los Angeles, Monterey Park, Oxnard, Rowland Heights, San Gabriel, Silver Lake, Torrance, West Los Angeles, and Westlake Village, California and Las Vegas, Nevada and a loan production office in the City of Industry, California.  

We generate our revenue primarily from interest received on loans and leases and, to a lesser extent, from interest received on investment securities.  We also generate income from noninterest sources, such as fees received in connection with various lending and deposit services, residential mortgage loan originations, loan servicing and gain on sales of loans.  Our principle expenses include interest expense on deposits, long-term debt and subordinated debentures, and operating expenses, such as salaries and employee benefits, occupancy and equipment, data processing, and income tax expense.  

CRITICAL ACCOUNTING POLICIES

Management has established various accounting policies that govern the application of GAAP in the preparation of our financial statements. Our significant accounting policies are described in the notes to the consolidated financial statements in our 2017 Annual Report. There have been no significant changes to our critical accounting policies as described in our 2017 Annual Report.

32

Certain accounting policies require management to make estimates and assumptions, which have a material impact on the carrying value of certain assets and liabilities; management considers these to be critical accounting policies. The estimates and assumptions management uses are based on historical experience and other factors, which management believes to be reasonable under the circumstances. Actual results could differ significantly from these estimates and assumptions, which could have a material impact on the carrying value of assets and liabilities at balance sheet dates and our results of operations for future reporting periods.  These policies relate to allowance for loan and lease losses (ALLL), income taxes and stock-based compensation.  For further information, refer to our 2017 Annual Report.

RECENT EVENTS

On April 23, 2018, RBB Bancorp and FAIC entered into the Merger Agreement, pursuant to which RBB Bancorp will acquire FAIC and its wholly-owned bank subsidiary, FAIB.  Pursuant to the terms and subject to the conditions of the Merger Agreement, at the Effective Time, each share of common stock of FAIC will be convertible into the right to receive (i) 1.3472 shares of RBB Bancorp’s common stock, and (ii) $15.30 in cash.  Holders of in-the-money FAIC Stock Options will receive an amount equal to (i) $51.00 per share of FAIC common stock subject to such FAIC Stock Options minus (ii) the aggregate exercise price with respect to such FAIC Stock Options.  In addition, FAIC will repurchase its currently-outstanding $17 million of preferred stock held by the U.S. Department of Treasury and issued under the Troubled Asset Relief Program.  

PRIMARY FACTORS AFFECTING COMPARABILITY

Each factor listed below materially affects the comparability of our results of operations and financial condition at and for the three months ended March 31, 2018 and March 31, 2017, and may affect the comparability of financial information we report in future fiscal periods.

Capital Transactions. We consummated our initial public offering in July 2017, and in connection with that capital transaction we issued 2,857,756 shares of our common stock for gross proceeds of $61.8 million.  

Accretion of Loan Discounts. In every bank acquisition acquired loans are valued at fair market value creating either a net discount or premium. Each loan has two types of adjustments, a credit discount and a market discount or premium. We have booked a net discount on all loans acquired in our previous acquisitions and the discount is accreted over the life of the loans. We also compare the credit discount to the allowance for loan losses calculated on the purchased loans and if the allowance for loan losses on purchased loans is greater than the discount, we will provide additional provisions for loan losses. The accretion of the discounts will cause fluctuations to our net interest margin and may affect the comparability of financial information we report in future fiscal periods. In addition, our allowance for loan losses to loans ratio may not be comparable to other banks without credit discounts. We accreted into income $353,000 and $1.1 million of loan discounts as of the three months ended March 31, 2018 and March 31, 2017, respectively.  As of March 31, 2018, we had $2.4 million in unaccreted discounts recorded and as of March 31, 2017 we had $7.0 million in unaccreted discounts recorded.

Our net interest margin benefits from accretion income associated with purchase accounting discounts established on purchased loans included in our acquisitions. For the three months ended March 31, 2018 and 2017, our reported net interest margin was 4.26% and 4.06%, respectively.   The impact of accretion income on our net interest margin for the three months ended March 31, 2018 and 2017 was to increase our reported net interest margin by 0.09% and 0.32%, respectively.

PRIMARY FACTORS USED TO EVALUATE OUR BUSINESS

Results of operations. In addition to net income, the primary factors we use to evaluate and manage our results of operations include net interest income, noninterest income and noninterest expense.

Net interest income. Net interest income represents interest income less interest expense. We generate interest income from interest, dividends and fees received on interest-earning assets, including loans and investment securities we own. We incur interest expense from interest paid on interest-bearing liabilities, including interest-bearing deposits, borrowings and other forms of indebtedness. Net interest income typically is the most significant contributor to our revenues and net income. To evaluate net interest income, we measure and monitor: (i) yields on our loans and other interest-earning assets; (ii) the costs of our deposits and other funding sources; (iii) our net interest spread; (iv) our net interest margin; and (v) our provisions for loan losses. Net interest spread is the difference between rates earned on interest-earning assets and rates paid on interest-bearing liabilities. Net interest margin is calculated as the annualized net interest income divided by average interest-earning assets. Because noninterest-bearing sources of funds, such as noninterest-bearing deposits and shareholders’ equity, also fund interest-earning assets, net interest margin includes the benefit of these noninterest-bearing sources.

33

Changes in market interest rates and interest we earn on interest-earning assets or pay on interest-bearing liabilities, as well as the volume and types of interest-earning assets, interest-bearing and noninterest-bearing liabilities and shareholders’ equity, usually have the largest impact on periodic changes in our net interest spread, net interest margin and net interest income. We measure net interest income before and after the provision for loan losses we maintain.

Noninterest Income. Noninterest income consists of, among other things: (i) service charges, fees and other, including trade finance fees; (ii) gains on sale of loans; (iii) loan servicing income; (iv) recoveries on loans acquired in business combinations; (v) Increase in cash surrender of life insurance; (vi) gains on sales of securities; and (vii) gains on sales of OREO.

Our income from service charges on deposit accounts is largely impacted by the volume, growth and type of deposits we hold, which are impacted by prevailing market conditions for our deposit products, our marketing efforts and other factors.

Our gains on sale of loans are primarily from sales of single-family residential mortgage loans and SBA loans. Our gains on sale of loans may be effected by changes in interest rates and general market conditions. Our servicing income, net of amortization is also, primarily from our single-family residential mortgages and SBA loan servicing portfolio. Our servicing income, net of amortization, may be effected by interest rate changes. Typically, when interest rates decrease, single-family residential mortgages pay off faster, resulting in a decrease in servicing income. The opposite is true with SBA loans, as increases in interest rates result in faster SBA loans payoffs, and decrease in servicing income from the existing SBA loan servicing portfolio.

Recoveries on loans acquired in business combinations are loan payments on loans that were fully charged-off prior to our acquisition of the acquired bank. Recoveries on loans acquired in a business combination tend to decrease over time as fully charged-off loans are recovered in full.

Our income from increases in cash surrender of life insurance is generated on bank owned life insurance. Our gains on sales of securities is income from the sale of securities within our securities portfolio and is dependent on U.S. Treasury interest rates. As Treasury rates increase, our security portfolio decreases in market value and as Treasury rates decrease, our securities portfolio increases in value. Our gain on sale on OREO reflects the selling price of repossessed real estate collateral, reduced by the book value of the asset and selling cost. Gains on OREO are dependent on the current real estate market and the number of repossessed properties.

Noninterest expense. Noninterest expense includes, among other things: (i) salaries and employee benefits; (ii) occupancy and equipment expenses; (iii) data processing expense; (iv) legal and professional expenses; (v) office expenses; (vi) marketing and business promotion expense; (vii) insurance and regulatory assessments; (viii) amortization of intangibles; (ix) OREO expenses, net of income; and (x) other expenses.

Salaries and employee benefits includes compensation, employee benefits and tax expenses for our personnel. Occupancy expense includes depreciation expense on our owned properties, lease expense on our leased properties and other occupancy-related expenses. Equipment expense includes furniture, fixtures and equipment related expenses. Data processing expenses include expenses paid to our third-party data processing system provider and other data service providers. Legal and professional fees include legal, accounting, consulting and other outsourcing arrangements. Office expenses include telephone, office supplies and postage and delivery expenses. Marketing and business promotion expense includes costs for advertising, promotions and sponsorships. Insurance and regulatory assessments includes FDIC insurance premiums, DBO fees and corporate insurance premiums. Amortization of intangible assets primarily represents the amortization of core deposit intangibles, which we recognized in connection with our acquisitions. OREO expenses are expenses to maintain OREO properties or prepare such properties for sale, net of any income generated from such properties. Other expenses include expenses associated with travel, meals, training, directors fees, and merger expenses. Noninterest expenses generally increase as we grow our business. Noninterest expenses have increased significantly over the past few years as we have grown organically and completed four acquisitions, and as we have built out and modernized our operational infrastructure and implemented our plan to build an efficient banking operation with significant capacity for growth.

PRIMARY FACTORS USED TO EVALUATE OUR FINANCIAL CONDITION

The primary factors we use to evaluate and manage our financial condition include asset quality, capital and liquidity.

Asset Quality. We manage the diversification and quality of our assets based upon factors that include the level, distribution, severity and trend of problem, classified, delinquent, nonaccrual, nonperforming and restructured assets, the adequacy of our allowance for loan losses, or the allowance, the diversification and quality of loan and investment portfolios, the extent of counterparty risks, credit risk concentrations and other factors.

Capital. Financial institution regulators have established guidelines for minimum capital ratios for banks, thrifts and bank holding companies. During the first quarter of 2015, we adopted the new Basel III regulatory capital framework as approved by federal banking agencies, which are subject to a multi-year phase-in period. The adoption of this new framework modified the calculation of the various capital ratios, added a new ratio, common equity Tier 1, and revised the adequately and well capitalized thresholds. In addition, Basel III establishes a new capital conservation buffer of 2.5% of risk-weighted assets, which is phased-in over a four-year period beginning January 1, 2016. Our capital ratios at March 31, 2018 exceeded all of the current well capitalized regulatory requirements.

34

We manage capital based upon factors that include: (i) the level and quality of capital and our overall financial condition; (ii) the trend and volume of problem assets; (iii) the adequacy of discounts and reserves; (iv) the level and quality of earnings; (v) the risk exposures in our balance sheet; (vi) the levels of Tier 1 and total capital; (vii) the Tier 1 capital ratio, the total capital ratio, the Tier 1 leverage ratio, and the common equity Tier 1 capital ratio; and (viii) other factors.

Liquidity. Our deposit base consists primarily of business accounts and deposits from the principals of such businesses. As a result, we have many depositors with balances over $250,000. We manage liquidity based upon factors that include the amount of core deposit relationships as a percentage of total deposits, the level of diversification of our funding sources, the allocation and amount of our deposits among deposit types, the short-term funding sources used to fund assets, the amount of non-deposit funding used to fund assets, the availability of unused funding sources, off-balance sheet obligations, the availability of assets to be readily converted into cash without undue loss, the amount of cash and liquid securities we hold, the re-pricing characteristics and maturities of our assets when compared to the re-pricing characteristics of our liabilities and other factors.

RESULTS OF OPERATIONS

The following discussion of our results of operations compares the three months ended March 31, 2018 to the three months ended March 31, 2017. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2018.

Our primary source of revenue is net interest income, which is the difference between interest income from earning assets (primarily loans and securities) and interest expense on funding sources (primarily interest-bearing deposits and borrowings). Net interest income is impacted by the level of interest-earning assets and related funding sources, as well as changes in the levels of interest rates. The difference between the average yield on earning assets and the average rate paid for interest-bearing liabilities is the net interest spread. Noninterest-bearing sources of funds, such as demand deposits and shareholders’ equity, also support earning assets. The impact of the noninterest-bearing sources of funds is captured in the net interest margin, which is calculated as net interest income divided by average earning assets.

(1) Earnings per share are calculated utilizing the two-class method. Basic earnings per share are calculated by dividing earnings to common shareholders by the weighted average number of common shares outstanding. Diluted earnings per share are calculated by dividing earnings by the weighted average number of shares adjusted for the dilutive effect of outstanding stock options using the treasury stock method.

(2) Efficiency ratio represents noninterest expenses, as adjusted, divided by the sum of fully taxable equivalent net interest income plus noninterest income, as adjusted. Noninterest expense adjustments exclude integration and acquisition related expenses (however, there were no integration and acquisition related expenses in the first quarters of 2018 or 2017). Noninterest income adjustments exclude bargain purchase gains, realized gains or losses from the sale of investment securities, gains or losses on sale of other assets and CDFI Fund grant.

(3) Tangible book value per share, adjusted return on average assets, adjusted return on average tangible common equity, return on average tangible common equity and tangible common equity to tangible assets are non-GAAP financial measures. See "Non-GAAP Financial Measures" for a reconciliation of these measures to their most comparable GAAP measures.

Net income of $8.8 million, or $0.52 per diluted share, for the first quarter of 2018 compares to net income for the first quarter of 2017 of $5.5 million, or $0.40 per diluted share. The increase in net income of $3.3 million was primarily due to the $2.9 million increase in net interest income resulting from average interest-earning asset growth of $216.5 million. The increase in average interest-earning assets was primarily from organic loan growth since the end of the first quarter of 2017. The increase was partially offset by a $1.7 million increase in noninterest expense, including increases of $768,000 in salaries and employee benefits, $645,000 in legal and professional expenses, and $121,000 in data processing expenses.  

For the three months ended March 31, 2018, the Company’s return on average assets was 2.15% and return on average tangible common equity was 15.01%. For the three months ended March 31, 2017, the return on average assets was 1.55% and the return on average tangible common equity was 14.66%.

Interest Rates and Operating Interest Differential

Increases and decreases in interest income and interest expense result from changes in average balances (volume) of interest-earning assets and interest-bearing liabilities, as well as changes in average interest rates. The following tables show the effect that these factors had on the interest earned on our interest-earning assets and the interest incurred on our interest-bearing liabilities. The effect of changes in volume is determined by multiplying the change in volume by the previous period’s average rate. Similarly, the effect of rate changes is calculated by multiplying the change in average rate by the previous period’s volume. Changes which are not due solely to volume or rate have been allocated to these categories based on the respective percent changes in average volume and average rate as they compare to each other.

(1) Includes income and average balances for FHLB stock, term federal funds, interest-bearing time deposits and other miscellaneous interest-earning assets.

(2) We have a minor amount of tax-exempt loans and securities, less than $6 million at March 31, 2018 and less than $1 million at March 31, 2017. Interest income and average rates for tax-exempt loans and securities are presented on a tax-equivalent basis as of March 31, 2018 and 2017.

(3) Average loan balances include nonaccrual loans and loans held for sale. Interest income on loans includes - amortization of deferred loan fees, net of deferred loan costs.

(4) Includes purchased receivables, which are short term loans made to investment grade companies and are used for cash - management purposes by the Company.

In the first quarter of 2018, we generated $16.4 million of net interest income, which was an increase of $2.9 million, or 21.7%, from the $13.5 million of net interest income we produced in the first quarter of 2017. The increase in net interest income was primarily due to a 19 basis point increase in the average yield on interest-earning assets and a 16.0% increase in the average balance of interest-earning assets, partially offset by a 12 basis point increase in the average rate paid on interest-bearing deposits reflecting an increase in deposit rates. The increase in the average balance of interest-earning assets reflected increases in securities, loans held for sale and total loans average balances, partially offset by decreases in federal funds sold, cash and other equivalents. Our deposit average balances increased by $135.7 million primarily due to the increase in NOW, money-market and demand deposit average balances partially offset by decreased time deposit balances. The increase in interest expense was primarily due to increased FHLB short-term advances during the quarter and increased time deposit rates.

38

For the three months ended March 31, 2018 and 2017, our reported net interest margin was 4.26% and 4.06%, respectively. Our net interest margin benefits from discount accretion on our purchased loan portfolios. Our net interest margin for the three months ended March 31, 2018 and 2017, excluding accretion income would have been 4.17% and 3.74%, respectively.

Interest Income.Total interest income was $20.2 million for the first quarter of 2018 compared to $16.8 million for the first quarter of 2017. The $3.4 million, or 20.4%, increase in interest income was primarily due to increases in earning asset average balances (partially offset by decreases in average federal funds sold and other cash equivalents) and increases in earning asset yields (partially offset by yield decreases in held to maturity securities, mortgage loans held for sale and real estate loans held for investment).

Interest and fees on loans for the first quarter of 2018 was $19.1 million compared to $16.0 million for the first quarter of 2017. The $3.0 million, or 19.0%, increase was primarily due to an 18 basis point increase in the average yield on loans plus a 8.3% increase in the average balance of loans outstanding, partially offset by lower accretion associated with purchase accounting discounts established on TomatoBank loans. Accretion income totaled $353,000 in the first quarter of 2018 compared to $1.1 million in the first quarter of 2017. The average yield on loans benefits from discount accretion on our purchased loan portfolio. For the three months ended March 31, 2018 and 2017, the yield on total loans was 5.69% and 5.51%, respectively, while the yield on total loans excluding accretion income would have been 5.46% and 4.74%, respectively.  The table below illustrates by loan type the accretion income for March 31, 2018 and March 31, 2017.  There were no additions due to acquisitions during the first quarters of 2018 and 2017.

	As of and for the
	three months

Interest income on our securities portfolio increased $282,000, or 101.5%, to $560,000 in the first quarter of 2018 compared to $278,000 in the first quarter of 2017. This increase is mainly attributable to an increase in average balances of $35.7 million or 79.2%, as corporate bonds increased by $19.8 million during the first quarter of 2018.

Interest income on federal funds sold, cash equivalents and other investments increased to $543,000 for the three months ended March 31, 2018 compared to $448,000 for the three months ended March 31, 2017. This increase was primarily due to an increase short-term interest rates partially offset by a decline in the level of short-term cash investments. The decrease in short-term cash investments is primarily due to deployment of the capital raised through our public offering in July 2017 into loans (held for investment and held for sale) since the third quarter of 2017.

Interest Expense.Interest expense on interest-bearing liabilities increased $487,000, or 15.0%, to $3.7 million for the first quarter of 2018 as compared to $3.2 million in the first quarter of 2017 due to increases in interest expense on both deposits and borrowings.

Interest expense on deposits increased to $2.7 million for the first quarter of 2018 as compared to $2.3 million for the first quarter of 2017. The $425,000, or 18.3%, increase in interest expense on deposits was primarily due to a 12 basis point increase in the average rate paid on interest-bearing deposits plus a 4.5% increase in the average balance of interest-bearing deposits.  The increase in the average balance of interest-bearing deposits resulted from increases in NOW and money market balances partially offset by decreases in savings and time deposits. The increase in the average rate paid was primarily due to the impact of higher market interest rates on deposits.

Interest expense on subordinated notes and subordinated debentures increased $8,000 to $913,000 in the first quarter of 2018 as compared to $905,000 in the first quarter of 2017.  Interest expense on FHLB short-term advances was $71,000 in the first quarter of 2018 as compared to $17,000 in the first quarter of 2017.

39

Provision for Loan Losses.The provision for loan losses was $184,000 in the first quarter of 2018 from zero in the first quarter of 2017, primarily due to organic loan growth.  

Noninterest Income.Noninterest income increased $23,000, or 0.94%, to $2.5 million for the first quarter of 2018, compared to $2.4 million in the first quarter of 2017. The following table sets forth the major components of our noninterest income for the first quarter of 2018 compared to the first quarter of 2017:

	For the three months ended
	March 31,					Increase (Decrease)
(dollars in thousands)	2018			2017		$			%
Noninterest income:
Service charges, fees and other	$	466		$	460	$	6			1.3	%
Gain on sale of loans		1,815			1,497		318			21.2	%
Loan servicing fee, net of amortization		(31	)		262		(293	)		-111.8	%
Recoveries on loans acquired in business combinations		6			28		(22	)		-78.6	%
Increase in cash surrender of life insurance		199			185		14			7.6	%
Total noninterest income	$	2,455		$	2,432	$	23			0.9	%

Service charges, fees and other income.Service charges, fees and other income totaled $466,000 in the first quarter of 2018 compared to $460,000 in the first quarter of 2017. The increase in services charges, fees and other income is attributable to increased fee income on deposit accounts primarily due to increased demand deposits and restructuring of our fee schedule.

Gain on sale of loans.Gain on sale of loans is comprised of gains on sale of single-family residential mortgage loans and gains on sale of SBA loans. Gain on sale of loans totaled $1.8 million in the first quarter of 2018 compared to $1.5 million in the first quarter of 2017.  In 2017, we began selling SBA loans on a quarterly basis.  We intend to sell such loans through the remaining quarters of 2018 in the amount of approximately $22 million per quarter. For the remainder of 2018, we plan to sell approximately $65 million of single-family mortgage loans in the second quarter and $40 million in the third and fourth quarters.

The following table shows the loans sold and gain on sales for the quarters ended March 31, 2018 and 2017:

	For the three months ended
(dollars in thousands)	March 31, 2018		March 31, 2017
Loans sold:
SBA	$	17,312	$	23,168
Mortgage		38,905		—
	$	56,217	$	23,168
Gain on loans sold:
SBA	$	833	$	1,498
Mortgage		982		—
	$	1,815	$	1,498

Loan servicing income, net of amortization.Loan servicing income, net of amortization was $(31,000) for the three months ended March 31, 2018 compared to $262,000 for the three months ended March 31, 2017. In the first quarter of 2018, $425,000 in deferred loan costs were expensed when $22.3 million in SBA serviced loans were paid off in the first quarter.   The single-family residential mortgage loan servicing portfolio was $406.6 million as of March 31, 2018 compared to $249.6 million as of March 31, 2017. The SBA loan servicing portfolio was $174.3 million as of March 31, 2018 compared to $131.9 million as of March 31, 2017. The increase in the respective servicing portfolios reflect the growth in our originations and sales of single-family residential and SBA loans from the first quarter of 2017 to the first quarter of 2018.

Recoveries on loans acquired in business combinations.Recoveries on loans acquired in business combinations decreased $22,000 to $6,000 in the quarter ended March 31, 2018 compared to $28,000 in the comparable quarter of 2017. This decrease is primarily due to our having completed collections on former VCBB and FAB loans, offset slightly by new recoveries resulting from the TomatoBank acquisition.

Increase in cash surrender of life insurance.Cash surrender value increased $14,000 to $199,000 in the quarter ended March 31, 2018 compared to $185,000 in the first quarter in 2017 primarily due to our purchase of an additional $10.0 million in bank owned life insurance (BOLI) in January 2017.

40

Gain on sale of OREO.  There were no OREO sales in the first quarters of 2018 or 2017.Noninterest expense increased $1.7 million, or 26.0%, to $8.3 million in the first quarter of 2018 compared to $6.6 million in the first quarter of 2017.  The following table sets forth the major components of our noninterest expense for the first quarter of 2018 compared to the first quarter of 2017:

	For the three months ended
	March 31,					Increase (Decrease)
(dollars in thousands)	2018		2017			$			%
Noninterest expense:
Salaries and employee benefits	$	4,951	$	4,183		$	768			18.4	%
Occupancy and equipment expenses		791		744			47			6.3	%
Data processing		473		352			121			34.4	%
Legal and professional		258		(387	)		645			-166.7	%
Office expenses		171		154			17			11.0	%
Marketing and business promotion		203		182			21			11.5	%
Insurance and regulatory assessments		210		205			5			2.4	%
Amortization of intangibles		81		94			(13	)		-13.8	%
OREO expenses (income)		7		14			(7	)		-50.0	%

Total noninterest expense	$	8,289	$	6,578		$	1,711			26.0	%

Salaries and employee benefits.The increase in salaries and employee benefits is due to additional employees in mortgage, BSA, compliance and finance/accounting (related to the Company going public), as well as normal salary increases.  Full-time equivalent staff was 219 at March 31, 2018 compared to 177 at March 31, 2017.

Legal and professional.Legal and professional expense was $(387,000) in the first quarter of 2017 because of $628,000 in accrual reversals.  The first quarter of 2018 expense was $258,000. Prior to 2017, we would accrue the entire amount of our estimate of the legal expense for a particular matter. Beginning in 2017, we began accruing for legal expenses as such expenses are incurred.

Other expenses.Other expenses increased $107,000, or 10.3%, to $1.1 million for the first quarter of 2018, compared to $1.0 million in the first quarter of 2017. This increase is primarily due an accumulation of small increases in various other accounts partially offset by a reduction in the provision for off-balance sheet commitments of $88,000 (which primarily consist of commercial real estate and commercial & industrial commitments).  

Income Tax Expense

Income tax expense was $1.6 million in the first quarter of 2018 compared to $3.9 million in the first quarter of 2017.  Effective tax rates were 15.2% in the first quarter of 2018, which includes the impact of a deduction for stock options exercised in the amount of $1.2 million, and 41.4% and the first quarter of 2017.  

On December 22, 2017, the “Tax Cuts and Jobs Act”, was signed into law, among other items, reducing the federal corporate

tax rate to 21% effective January 1, 2018, which contributed to the reduction of our effective tax rate in the first quarter on 2018.Net Income

Net income amounted to $8.8 million for the first quarter 2018, a $3.4 million or 61.1% increase from the first quarter of 2017, primarily due to improved net interest income and a decrease in tax expense, which was partially offset by increased non-interest expense.

41

ANALYSIS OF FINANCIAL CONDITION

Total assets increased by $21.8 million, or 1.29%, to $1.7 billion as of March 31, 2018. This increase in total assets primarily was attributable to increasing securities available for sale by $17.9 million, increasing loans held for investment by $12.9 million, mortgage loans held for sale increased by $57.5 million in the first three-months of 2018, partially offset by a reduction in cash and cash equivalents of $71.5 million.

The weighted-average yield on the total investment portfolio at March 31, 2018 was 2.70% with a weighted-average life of 5.47 years. This compares to a weighted-average yield of 2.70% at December 31, 2017 with a weighted-average life of 6.6 years. The weighted average life is the average number of years that each dollar of unpaid principal due remains outstanding. Average life is computed as the weighted-average time to the receipt of all future cash flows, using as the weights the dollar amounts of the principal pay-downs.

Approximately 49% of the securities in the total investment portfolio, at March 31, 2018, are issued by the U.S. government or U.S. government-sponsored agencies and enterprises, which have the implied guarantee of payment of principal and interest. As of March 31, 2018, no U.S. government agency bonds are callable.

The tables below show the Company’s investment securities’ gross unrealized losses and fair value by investment category and length of time that individual securities have been in a continuous unrealized loss position, at March 31, 2018 and December 31, 2017. The unrealized losses on these securities were primarily attributed to changes in interest rates. The issuers of these securities have not, to our knowledge, evidenced any cause for default on these securities. These securities have fluctuated in value since their purchase dates as market interest rates have fluctuated. However, we have the ability and the intention to hold these securities until their fair values recover to cost or maturity. As such, management does not deem these securities to be other-than-temporarily-impaired.  A summary of our analysis of these securities and the unrealized losses is described more fully in Note 2 — Investment Securities in the notes to the 2017 consolidated financial statements included in the 2017 Annual Report. Economic trends may adversely affect the value of the portfolio of investment securities that we hold.

Loans

The loan portfolio is the largest category of our earning assets. At March 31, 2018, total loans, net of allowance for loan losses, totaled $1.2 billion. Prior to 2014, we mainly had two lending products, commercial and industrial loans and commercial real estate (CRE) loans. In 2014, we made the strategic move to diversify our lending into single-family residential mortgage and SBA loans. The following table presents the balance and associated percentage of each major category in our loan portfolio at March 31, 2018 and December 31, 2017:

Net loans increased $12.7 million, or 1.0%, to $1.2 billion at March 31, 2018 as compared to December 31, 2017. The increase in net loans primarily resulted from organic growth in construction, commercial real estate and single-family residential mortgage loans, which was partially offset by the sale of SBA loans and reduction in commercial and industrial loans.

Outstanding loan balances increased due to new loan originations and advances on outstanding commitments, net of amounts received for loan payments and payoffs.

Commercial and industrial loans. We provide a mix of variable and fixed rate commercial and industrial loans. The loans are typically made to small- and medium-sized manufacturing, wholesale, retail and service businesses for working capital needs, business expansions and for international trade financing. Commercial and industrial loans include lines of credit with a maturity of one year or less, commercial and industrial term loans with maturities of five years or less, shared national credits with maturities of five years or less, mortgage warehouse lines with a maturity of one year or less, bank subordinated debentures with a maturity of 10 years, purchased receivables with a maturity of two months or less and international trade discounts with a maturity of three months or less. Substantially all of our commercial and industrial loans are collateralized by business assets or by real estate.

Commercial and industrial loans decreased $2.4 million, or 0.8%, to $278.4 million as of March 31, 2018 compared to $280.8 million at December 31, 2017. This decrease resulted primarily from a decrease in commercial and industrial lines of credit of $20.2 million partially offset by an increase in warehouse lines of credit of $11.2 million and shared national credits of $3.8 million.

Commercial real estate loans. Commercial real estate loans include owner-occupied and non-occupied commercial real estate, multi-family residential and single-family residential loans originated for a business purpose. The interest rate for the majority of these loans are Prime based and have a maturity of five years or less except for the single-family residential loans originated for a business purpose which may have a maturity of one year. At March 31, 2018, approximately 6.8% of the commercial real estate portfolio consisted of fixed-rate loans. Our policy maximum loan-to-value, or LTV, is 75% for commercial real estate loans. The total commercial real estate portfolio totaled $358.5 million at March 31, 2018 and $354.8 million as of December 31, 2017, of which $199.3 million and $204.6 million, respectively, are secured by owner occupied properties. The multi-family residential loan portfolio totaled $107.6 million as of March 31, 2018 and $102.7 million as of December 31, 2017.  The single-family residential loan portfolio originated for a business purpose totaled $33.9 million as of March 31, 2018 and $38.5 million as of December 31, 2017.

Commercial real estate loans increased $4.0 million, or 0.8%, to $500.1 million at March 31, 2018 as compared to $496.0 million at December 31, 2017. This increase resulted primarily from normal business development.

Construction and land development loans. Construction and land development loans increased $9.3 million, or 10.2%, to $101.2 million at March 31, 2018 as compared to $91.9 million at December 31, 2017. This increase in construction and land development loans was primarily due to construction loan originations exceeding loan repayments.  

The following table shows the categories of our construction and land development portfolio as of March 31, 2018 and December 31, 2017:

Small Business Administration guaranteed loans. We are designated a Preferred Lender under the SBA Preferred Lender Program. We offer mostly SBA 7(a) variable-rate loans. We generally sell the 75% guaranteed portion of the SBA loans that we originate. Our SBA loans are typically made to small-sized manufacturing, wholesale, retail, hotel/motel and service businesses for

46

working capital needs or business expansions. SBA loans can have any maturity up to 25 years. Typically, non-real estate secured loans mature in less than 10 years.  Collateral may also include inventory, accounts receivable and equipment, and includes personal guarantees. Our unguaranteed SBA loans collateralized by real estate are monitored by collateral type and are included in our CRE Concentration Guidance.

We originate SBA loans through our branch staff, loan officers and through SBA brokers. For the first three months of 2018, $8.4 million, or 100%, of SBA loan originations were produced by branch staff and loan officers.  We did not have any loans referred to us by SBA brokers in the first quarter of 2018.

As of March 31, 2018 our SBA portfolio totaled $114.7 million of which $41.4 million is guaranteed by the SBA and $73.3 million is unguaranteed, of which $69.5 million is secured by real estate and $3.8 million is unsecured or secured by business assets. We monitor the unguaranteed portfolio by type of real estate collateral. As of March 31, 2018, $37.4 million or 51.0% is secured by hotel/motels; $12.1 million or 16.5% by gas stations; and $23.9 million or 32.5% in other real estate types. We further analyze the unguaranteed portfolio by location. As of March 31, 2018, $30.0 million or 41.0% is located in California; $3.0 million or 4.1% is located in Nevada; $14.2 million or 19.3% is located in Texas; $10.6 million or 14.5% is located in Washington; and $15.5 million or 21.1% is located in other states.

SBA loans decreased $16.8 million, or 12.8%, to $114.7 million at March 31, 2018 compared to $131.4 million at December 31, 2017. This decrease was primarily due to loan sales of $17.3 million, partially offset by $8.4 million in originations in the first three-months of 2018.  In 2017, we began selling SBA loans quarterly, whereas previously, we primarily sold SBA loans annually in November of each year.

Single-family residential real estate loans. We originate mainly non-qualified, alternative documentation single-family residential mortgage loans through correspondent relationships or through our branch network or retail channel. The loan product is a seven-year hybrid adjustable mortgage with a current start rate of 4.75% which re-prices after seven years to the one-year LIBOR plus 2.75%. As of March 31, 2018, the average loan-to-value of the portfolio was 59.5%, the average FICO score was 752 and the average duration of the portfolio was 4 years. We also offer qualified single-family residential mortgage loans as a correspondent to a national financial institution.

We originate these non-qualified single-family residential mortgage loans both to sell and hold for investment. The loans held for investment are generally originated through our retail branch network to our customers, many of whom establish a deposit relationships with us. During the first three-months of 2018, we originated $28.1 million of such loans through our retail channel and $91.8 million through our correspondent channel. We sell many of these non-qualified single-family residential mortgage loans to other Asian-American banks. While our loan sales to date have been primarily to two banks, we expect to be expanding our network of banks who will purchase our single-family loan product.

Single-family residential real estate loans, which include $1.9 million of home equity loans, increased $18.7 million, or 7.5%, to $267.6 million as of March 31, 2018 as compared to $248.9 million as of December 31, 2017. In addition, loans held for sale increased $57.5 million or 45.7% to $183.4 million as of March 31, 2018 compared to $125.8 million December 31, 2017. The increase in loans held for sale is mainly due to a decrease in selling single-family residential mortgage loans in the first quarter of 2018 compared to the same period in 2017.  

Loan Quality

We use what we believe is a comprehensive methodology to monitor credit quality and prudently manage credit concentration within our loan portfolio. Our underwriting policies and practices govern the risk profile and credit and geographic concentration for our loan portfolio. We also have what we believe to be a comprehensive methodology to monitor these credit quality standards, including a risk classification system that identifies potential problem loans based on risk characteristics by loan type as well as the early identification of deterioration at the individual loan level. In addition to our allowance for loan losses, our purchase discounts on acquired loans provide additional protections against credit losses.

Discounts on Purchased Loans. At acquisition we hire a third-party to determine the fair value of loans acquired. In many of the cases fair values were determined by estimating the cash flows expected to result from those loans and discounting them at appropriate market rates. The excess of expected cash flows above the fair value of the majority of loans will be accreted to interest income over the remaining lives of the loans in accordance with FASB Accounting Standards Codification, or ASC 310-20.

None of the loans we acquired after 2011 had evidence of deterioration of credit quality since origination for which it was probable, at acquisition, that the Company would be unable to collect all contractually required payments receivable. Loans acquired that had evidence of deterioration of credit quality since origination are referred to as PCI (purchase credit impaired) loans.

47

With our acquisitions of FAB and VCBB, we acquired $16.7 million contractual amount due with a fair value of $9.7 million of PCI loans. The outstanding balance and carrying amount of PCI loans as of March 31, 2018 and December 31, 2017 were $319,000 and $313,000 and $322,000 and $315,000, respectively. For these PCI loans, the Company did not record an allowance for loan losses for 2018 or 2017 as there were no significant reductions in the expected cash flows.

Analysis of the Allowance for Loan Losses. The following table allocates the allowance for loan losses, or the allowance, by category:

	As of March 31, 2018				As of December 31,  2017
(dollars in thousands)	$		% (1)		$		% (1)

Allowance for loan losses	$	13,957		1.11	$	13,773		1.10

(1) Represents the percentage of the allowance to total loans in the respective category.

(2) Includes non-farm and non-residential real estate loans, multi-family residential and single-family residential loans originated for a business purpose.

The allowance and the balance of accretable credit discounts represent our estimate of probable and reasonably estimable credit losses inherent in loans held for investment as of the respective balance sheet date. The accretable credit discount was $2.4 million at March 31, 2018.  Including the non-accretable credit discount as a percentage of the allowance and credit discounts to loans was 1.2%.

Allowance for loan losses. Our methodology for assessing the appropriateness of the allowance for loan losses includes a general allowance for performing loans, which are grouped based on similar characteristics, and a specific allowance for individual impaired loans or loans considered by management to be in a high-risk category. General allowances are established based on a number of factors, including historical loss rates, an assessment of portfolio trends and conditions, accrual status and economic conditions.

For commercial and industrial, SBA, commercial real estate, construction and land development and single family residential mortgage loans held for investment, a specific allowance may be assigned to individual loans based on an impairment analysis. Loans are considered impaired when it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. The amount of impairment is based on an analysis of the most probable source of repayment, including the present value of the loan’s expected future cash flows, the estimated market value or the fair value of the underlying collateral. Interest income on impaired loans is accrued as earned, unless the loan is placed on nonaccrual status.

Credit-discount on loans purchased through acquisition. Purchased loans are recorded at market value in two categories, credit discount and liquidity discount and premiums. The remaining credit discount at the end of a period is compared to the analysis for loan losses for each acquisition. If the credit discount is greater than the expected loss no additional provision is needed. The following table shows our credit discounts by loan portfolio for purchased loans only as of March 31, 2018 and December 31, 2017.

Individual loans considered to be uncollectible are charged off against the allowance. Factors used in determining the amount and timing of charge-offs on loans include consideration of the loan type, length of delinquency, sufficiency of collateral value, lien priority and the overall financial condition of the borrower. Collateral value is determined using updated appraisals and/or other market comparable information. Charge-offs are generally taken on loans once the impairment is determined to be other-than-temporary. Recoveries on loans previously charged off are added to the allowance.  Net charge-offs to average loans was none for the first three months of March 31, 2018 and 2017.

The allowance for loan losses was $14.0 million at March 31, 2018 compared to $13.8 million at December 31, 2017. The $184,000 increase at March 31, 2018 compared to December 31, 2017 was due to the increase in loan volume.  There were no net loan charge-offs in the first quarter.

We analyze the loan portfolio, including delinquencies, concentrations, and risk characteristics, at least quarterly in order to assess the overall level of the allowance and nonaccretable discounts. We also rely on internal and external loan review procedures to further assess individual loans and loan pools, and economic data for overall industry and geographic trends.

In determining the allowance and the related provision for loan losses, we consider three principal elements:  (i) valuation allowances based upon probable losses identified during the review of impaired commercial and industrial, commercial real estate, construction and land development loans, (ii) allocations, by loan classes, on loan portfolios based on historical loan loss experience and qualitative factors and (iii) review of the credit discounts in relationship to the valuation allowance calculated for purchased loans. Provisions for loan losses are charged to operations to record changes to the total allowance to a level deemed appropriate by us.

The following table provides an analysis of the allowance for loan losses, provision for loan losses and net charge-offs for the three months ended March 31, 2018 and 2017:

Problem Loans. Loans are considered delinquent when principal or interest payments are past due 30 days or more; delinquent loans may remain on accrual status between 30 days and 89 days past due. Loans on which the accrual of interest has been discontinued are designated as nonaccrual loans. Typically, the accrual of interest on loans is discontinued when principal or interest payments are past due 90 days or when, in the opinion of management, there is a reasonable doubt as to collectability in the normal course of business. When loans are placed on nonaccrual status, all interest previously accrued but not collected is reversed against current period interest income. Income on nonaccrual loans is subsequently recognized only to the extent that cash is received and the loan’s principal balance is deemed collectible. Loans are restored to accrual status when loans become well-secured and management believes full collectability of principal and interest is probable.

A loan is considered impaired when it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. Impaired loans include loans on nonaccrual status and performing restructured loans. Income from loans on nonaccrual status is recognized to the extent cash is received and when the loan’s principal balance is deemed collectible. Depending on a particular loan’s circumstances, we measure impairment of a loan based upon either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral

49

less estimated costs to sell if the loan is collateral dependent. A loan is considered collateral dependent when repayment of the loan is based solely on the liquidation of the collateral. Fair value, where possible, is determined by independent appraisals, typically on an annual basis. Between appraisal periods, the fair value  may be adjusted based on specific events, such as if deterioration of quality of the collateral comes to our attention as part of our problem loan monitoring process, or if discussions with the borrower lead us to believe the last appraised value no longer reflects the actual market for the collateral. The impairment amount on a collateral-dependent loan is charged-off to the allowance if deemed not collectible and the impairment amount on a loan that is not collateral-dependent is set up as a specific reserve.

In cases where a borrower experiences financial difficulties and we make certain concessionary modifications to contractual terms, the loan is classified as a troubled debt restructuring, or TDR. These concessions may include a reduction of the interest rate, principal or accrued interest, extension of the maturity date or other actions intended to minimize potential losses. Loans restructured at a rate equal to or greater than that of a new loan with comparable risk at the time the loan is modified may be excluded from restructured loan disclosures in years subsequent to the restructuring if the loans are in compliance with their modified terms. A restructured loan is considered impaired despite its accrual status and a specific reserve is calculated based on the present value of expected cash flows discounted at the loan’s effective interest rate or the fair value of the collateral less estimated costs to sell if the loan is collateral dependent.

Real estate we acquire as a result of foreclosure or by deed-in-lieu of foreclosure is classified as OREO until sold, and is carried at the balance of the loan at the time of foreclosure or at estimated fair value less estimated costs to sell, whichever is less.

The following table sets forth the allocation of our nonperforming assets among our different asset categories as of the dates indicated. Nonperforming loans include nonaccrual loans, loans past due 90 days or more and still accruing interest, and loans modified under troubled debt restructurings. Nonperforming loans exclude PCI loans. The balances of nonperforming loans reflect the net investment in these assets.

Nonperforming loans to total loans		0.35	%		0.21	%
Nonperforming assets to total assets		0.28	%		0.17	%

The increase in nonperforming loans at March 31, 2018 was primarily due to a $1.4 million SBA loan that was placed on nonaccrual status as of March 31, 2018 because it did not meet the Company’s cash flow requirements, but has become current subsequent to quarter end.  The Company believes that no impairment exists, as there is more than sufficient collateral value supporting the loan.

Our 30-89 day delinquent loans decreased to $2.2 million as of March 31, 2018.  Of this amount, all have been brought current or been paid-off except for $994,000.  

As of March 31, 2018, there were no loans over 90 days past due and still accruing.  There was one loan over 90 days past due and still accruing in the amount of $71,000 as of December 31, 2017.

We did not recognize any interest income on nonaccrual loans during the periods ended March 31, 2018 and December 31, 2017 while the loans were in nonaccrual status. We recognized interest income on commercial and commercial real estate loans modified under troubled debt restructurings of $348,000 and $301,000 during the periods ended March 31, 2018 and December 31, 2017, respectively.

We utilize an asset risk classification system in compliance with guidelines established by the FDIC as part of our efforts to improve asset quality. In connection with examinations of insured institutions, examiners have the authority to identify problem assets and, if appropriate, classify them. There are three classifications for problem assets: “substandard,” “doubtful,” and “loss.” Substandard assets have one or more defined weaknesses and are characterized by the distinct possibility that the insured institution will sustain some loss if the deficiencies are not corrected. Doubtful assets have the weaknesses of substandard assets with the additional characteristic that the weaknesses make collection or liquidation in full questionable and there is a high probability of loss based on currently existing facts, conditions and values. An asset classified as loss is not considered collectable and is of such little value that continuance as an asset is not warranted.

We use a risk grading system to categorize and determine the credit risk of our loans. Potential problem loans include loans with a risk grade of 6, which are “special mention,” loans with a risk grade of 7, which are “substandard” loans that are generally not considered to be impaired and loans with a risk grade of 8, which are “doubtful” loans generally considered to be impaired. These loans generally require more frequent loan officer contact and receipt of financial data to closely monitor borrower performance. Potential problem loans are managed and monitored regularly through a number of processes, procedures and committees, including oversight by a loan administration committee comprised of executive officers and other members of the Bank’s senior management.

Cash and Cash Equivalents. Cash and cash equivalents increased $71.5 million, or 47.7%, to $78.5 million as of March 31, 2018 as compared to $150.0 million at December 31, 2017. This decrease was primarily due to $23.9 million used in operating activities, $61. 2 million used in investing activities partially offset by $13.6 million from financing activities.

Goodwill and Other Intangible Assets. Goodwill was $29.9 million at March 31, 2018 and December 31, 2017, respectively. Goodwill represents the excess of the consideration paid over the fair value of the net assets acquired. Our other intangible assets, which consist of core deposit intangibles, were $1.4 million and $1.4 million at March 31, 2018 and December 31, 2017, respectively. These assets are amortized primarily on an accelerated basis over their estimated useful lives, generally over a period of 3 to 10 years.

Liabilities. Total liabilities increased $11.1 million to $1.4 billion, or 0.8%, at March 31, 2018 from December 31, 2017, primarily due to deposit growth.

Deposits. As a Chinese-American business bank that focuses on successful businesses and their owners, many of our depositors choose to leave large deposits with us. The Bank measures core deposits by reviewing all relationships over $250,000 on a quarterly basis. We track all deposit relationships over $250,000 on a quarterly basis and consider a relationship to be core if there are any three or more of the following attributes: (i) relationships with us (as a director or shareholder); (ii) deposits within our market area; (iii) additional non-deposit services with us; (iv) electronic banking services with us; (v) active demand deposit account with us; (vi) deposits at market interest rates; and (vii) longevity of the relationship with us. We consider all deposit relationships under $250,000 as a core relationship except for time deposits originated through an internet service. This differs from the traditional definition of core deposits which is demand and savings deposits plus time deposits less than $250,000. As many of our customers have more than $250,000 on deposit with us, we believe that using this method reflects a more accurate assessment of our deposit base. As of March 31, 2018, the Bank considers $1.1 billion or 80.3% of our deposits as core relationships.  As of March 31, 2018, our top ten deposit relationships totaled $338.6 million, of which five are related to directors and shareholders of the Company for a total of $115.4 million or 34.1% of our top ten deposit relationships. As of March 31, 2018, our directors and shareholders with deposits over $250,000 totaled $255.6 million or 35.0% of all relationships over $250,000.

The following table summarizes our average deposit balances and weighted average rates at March 31, 2018 and December 31, 2017:

The following table sets forth the maturity of time deposits of $250,000 or more as of March 31, 2018:

	As of March 31, 2018

Total	$	107,488	$	121,392	$	160,341	$	2,340	$	391,561

(1) Wholesale deposits are defined as time deposits under $250,000 originated through via internet rate line and/or through other deposit originators and are considered non-core deposits.

We acquired time deposits from the internet and outside deposits originators as needed to supplement liquidity. These time deposits are primarily under $250,000 and we do not consider them core deposits. The total amount of such deposits as of March 31, 2018 was $26.9 million or 2.0% of total deposits. The balances of such deposits as of December 31, 2017 were $29.5 million. The Bank did not have any brokered deposits during any of the time periods presented.

Total deposits increased $165.5 million to $1.4 billion at March 31, 2018 as compared to $1.3 billion at December 31, 2017, as we grew non-maturity deposit categories. As of March 31, 2018, total deposits were comprised of 23% noninterest-bearing demand accounts, 29% interest-bearing transaction accounts and 48% of time deposits.

Short-Term Borrowings. In addition to deposits, we use short-term borrowings, such as federal funds purchased and FHLB advances, as a source of funds to meet the daily liquidity needs of our customers and fund growth in earning assets.  We did not have any short-term borrowings as of March 31, 2018 but did have $25.0 million outstanding at December 31, 2017. The weighted average interest rate on our short-term borrowings was 0.77% and 0.18% for the three months ended March 31, 2018 and , 2017, respectively.  The following table sets forth information on our short-term FHLB advances during the periods presented:

Weighted average interest rate:
During period		1.61	%		0.67	%
End of period		—			0.69	%

Long-Term Debt. Long-term debt consists of subordinated notes.  As of March 31, 2018 the aggregate outstanding principal amount of our subordinated notes was $49.6 million as compared to $49.5 million at December 31, 2017.  The subordinated notes have a maturity date of April 1, 2026 at a fixed rate of 6.5% for the first five years and a floating rate based on the three-month London Interbank Offered Rate (LIBOR) plus 516 basis points thereafter. Under the terms of our subordinated notes and the related subordinated notes purchase agreements, we are not permitted to declare or pay any dividends on our capital stock if an event of default occurs under the terms of the long term debt.

Subordinated Debentures. We acquired $5.2 million subordinated debentures as part of the TFC acquisition (TFC Statutory Trust I) and recorded it at fair value of $3.3 million. The fair value adjustment is being accreted over the remaining life of the securities. As of March 31, 2018 and December 31, 2017, we had $3.4 million, and $3.4 million, respectively, of subordinated debentures outstanding. These debentures mature on March 15, 2037 and have a variable rate of interest equal to the three-month LIBOR plus 1.65%.  The interest rates on these debentures were 3.77% and 3.24%, respectively, on March 31, 2018 and December 31, 2017.

In July 2017, British banking regulators announced plans to eliminate the LIBOR rate by the end of 2021, before these subordinated notes and debentures mature.  For these subordinated notes and debentures, there are provisions for amendments to establish a new interest rate benchmark.

Capital Resources and Liquidity Management

Capital Resources. Shareholders’ equity is influenced primarily by earnings, dividends, sales and redemptions of common stock and preferred stock and changes in accumulated other comprehensive income caused primarily by fluctuations in unrealized holding gains or losses, net of taxes, on available for sale investment securities.

Shareholders’ equity increased $10.6 million, or 4.0%, to $275.8 million during the first three months of 2018, reflecting $8.8 million of net income and $3.5 million from the exercise of stock options partially offset by a $597,000 decrease in accumulated other comprehensive income exceeded $1.3 million of common dividends declared. The decrease in accumulated other comprehensive income primarily resulted from increases in unrealized gains on available for sale securities.

On July 27, 2017, we completed our initial public offering of 3,750,000 shares at a price to the public of $23.00 per share and a total offering size of $86,250,000. RBB Bancorp sold 2,857,756 shares and selling shareholders sold 892,244 shares of RBB Bancorp’s common stock in the initial public offering. The offering resulted in gross proceeds to RBB Bancorp of approximately $65.7 million. RBB Bancorp contributed $25 million of the net proceeds received from this offering to the Bank. Our stock now trades on the Nasdaq Global Select Market under the symbol “RBB”.  The increase to capital net of expenses was approximately $60.2 million in July 2017.

Liquidity Management. Liquidity refers to the measure of our ability to meet the cash flow requirements of depositors and borrowers, while at the same time meeting our operating, capital and strategic cash flow needs, all at a reasonable cost. We continuously monitor our liquidity position to ensure that assets and liabilities are managed in a manner that will meet all short-term and long-term cash requirements. We manage our liquidity position to meet the daily cash flow needs of customers, while maintaining an appropriate balance between assets and liabilities to meet the return on investment objectives of our shareholders.

Our liquidity position is supported by management of liquid assets and liabilities and access to alternative sources of funds. Liquid assets include cash, interest-earning deposits in banks, federal funds sold, available for sale securities, term federal funds, purchased receivables and maturing or prepaying balances in our securities and loan portfolios. Liquid liabilities include core deposits, federal funds purchased, securities sold under repurchase agreements and other borrowings. Other sources of liquidity include the sale of loans, the ability to acquire additional national market noncore deposits, the issuance of additional collateralized borrowings such as FHLB advances, the issuance of debt securities, additional borrowings through the Federal Reserve’s discount window and the issuance of preferred or common securities. Our short-term and long-term liquidity requirements are primarily to fund on-going operations, including payment of interest on deposits and debt, extensions of credit to borrowers, capital expenditures and shareholder dividends. These liquidity requirements are met primarily through cash flow from operations, redeployment of prepaying and maturing balances in our loan and investment portfolios, debt financing and increases in customer deposits. For additional information regarding our operating, investing and financing cash flows, see the consolidated statements of cash flows provided in our consolidated financial statements.

Integral to our liquidity management is the administration of short-term borrowings. To the extent we are unable to obtain sufficient liquidity through core deposits, we seek to meet our liquidity needs through wholesale funding or other borrowings on either a short- or long-term basis.

As of March 31, 2018 and December 31, 2017, we had $49.0 million and $49.0 million of unsecured federal funds lines, respectively, with no amounts advanced against the lines as of such dates. In addition, lines of credit from the Federal Reserve Discount Window at March 31, 2018 and December 31, 2017 were $15.2 million and $15.0 million, respectively. Federal Reserve Discount Window lines were collateralized by a pool of commercial real estate loans totaling $25.3 million and $25.6 million as of March 31, 2018 and December 31, 2017, respectively. We did not have any borrowings outstanding with the Federal Reserve at March 31, 2018 and December 31, 2017 and our borrowing capacity is limited only by eligible collateral.

At March 31, 2018 we did not have any FHLB advances outstanding. At December 31, 2017 we have $25.0 million in FHLB advances outstanding.  Based on the values of loans pledged as collateral, we had $326.9 million and $387.3 million of additional borrowing capacity with the FHLB as of March 31, 2018 and December 31, 2017, respectively. We also maintain relationships in the capital markets with brokers and dealers to issue certificates of deposit.

The Company is a corporation separate and apart from the Bank and, therefore, must provide for its own liquidity. The Company’s main source of funding is dividends declared and paid to us by the Bank and RAM. There are statutory, regulatory and debt covenant limitations that affect the ability of the Bank to pay dividends to the Company. Management believes that these limitations will not impact our ability to meet our ongoing short-term cash obligations.

53

Regulatory Capital Requirements

We are subject to various regulatory capital requirements administered by the federal and state banking regulators. Failure to meet regulatory capital requirements may result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our financial statements. Under capital adequacy guidelines and the regulatory framework for “prompt corrective action” (described below), we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting policies.

In the wake of the global financial crisis of 2008 and 2009, the role of capital has become fundamentally more important, as banking regulators have concluded that the amount and quality of capital held by banking organizations was insufficient to absorb losses during periods of severely distressed economic conditions. The Dodd-Frank Act and new banking regulations promulgated by the U.S. federal banking regulators to implement Basel III have established strengthened capital standards for banks and bank holding companies and require more capital to be held in the form of common stock. These provisions, which generally became applicable to the Company and the Bank on January 1, 2015, impose meaningfully more stringent regulatory capital requirements than those applicable to the Company and the Bank prior to that date. In addition, the Basel III regulations will implement a concept known as the “capital conservation buffer.” In general, banks and bank holding companies will be required to hold a buffer of common equity Tier 1 capital equal to 2.5% of risk-weighted assets over each minimum capital ratio to avoid being subject to limits on capital distributions (e.g., dividends, stock buybacks, etc.) and certain discretionary bonus payments to executive officers. For community banks, the capital conservation buffer requirement commenced on January 1, 2016, with a gradual phase-in. Full compliance with the capital conservation buffer will be required by January 1, 2019.

The table below summarizes the minimum capital requirements applicable to us and the Bank pursuant to Basel III regulations as of the dates reflected and assuming the capital conservation buffer has been fully-phased in. The minimum capital requirements are only regulatory minimums and banking regulators can impose higher requirements on individual institutions. For example, banks and bank holding companies experiencing internal growth or making acquisitions generally will be expected to maintain strong capital positions substantially above the minimum supervisory levels. Higher capital levels may also be required if warranted by the particular circumstances or risk profiles of individual banking organizations. The table below also summarizes the capital requirements applicable to us and the Bank in order to be considered “well-capitalized” from a regulatory perspective, as well as our and the Bank’s capital ratios as of March 31, 2018 and December 31, 2017. We and the Bank exceeded all regulatory capital requirements under Basel III and were considered to be “well-capitalized” as of the dates reflected in the table below:

	Ratio at March 31, 2018	Ratio at December 31, 2017	Regulatory Capital Ratio Requirements	Regulatory Capital Ratio Requirements, including fully phased-in Capital Conservation Buffer	Minimum Requirement for "Well Capitalized" Depository Institution
Tier 1 Leverage Ratio
Consolidated	15.24%	14.35%	4.00%	4.00%	N/A
Bank	14.83%	14.50%	4.00%	4.00%	5.00%
Common Equity Tier 1 Risk-Based Capital Ratio (1)
Consolidated	17.98%	17.54%	4.50%	7.00%	N/A
Bank	17.75%	17.42%	4.50%	7.00%	6.50%
Tier 1 Risk-Based Capital Ratio
Consolidated	18.24%	17.80%	6.00%	8.50%	N/A
Bank	17.75%	17.42%	6.00%	8.50%	8.00%
Total Risk-Based Capital Ratio
Consolidated	22.93%	22.55%	8.00%	10.50%	N/A
Bank	18.82%	18.47%	8.00%	10.50%	10.00%

(1) The common equity tier 1 risk-based ratio, or CET1, is a new ratio created by the Basel III regulations beginning January 1, 2015.

The Basel III regulations also revise the definition of capital and describe the capital components and eligibility criteria for common equity Tier 1 capital, additional Tier 1 capital and Tier 2 capital. The most significant changes to the capital criteria are that: (i) the prior concept of unrestricted Tier 1 capital and restricted Tier 1 capital has been replaced with additional Tier 1 capital and a regulatory capital ratio that is based on common equity Tier 1 capital; and (ii) trust preferred securities and cumulative perpetual preferred stock issued after May 19, 2010 no longer qualify as Tier 1 capital. This change is already effective due to the Dodd-Frank Act, although such instruments issued prior to May 19, 2010 continue to qualify as Tier 1 capital (assuming they qualified as such under the prior regulatory capital standards), subject to the 25% of Tier 1 capital limit.

Off-Balance Sheet Arrangements

We have limited off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our financial condition, revenues, expenses, results of operations, liquidity, capital expenditures or capital resources.

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 loan 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.

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.

Non-GAAP Financial Measures

Some of the financial measures included in this Form 10-Q are not measures of financial performance recognized by GAAP. These non-GAAP financial measures include “tangible common equity to tangible assets,” “tangible book value per share,” “return on average tangible common equity,” “adjusted earnings,” “adjusted diluted earnings per share,” “adjusted return on average assets,” and “adjusted return on average tangible common equity.” Our management uses these non-GAAP financial measures in its analysis of our performance.

Tangible Common Equity to Tangible Assets Ratio and Tangible Book Value Per Share. The tangible common equity to tangible assets ratio and tangible book value per share are non-GAAP measures generally used by financial analysts and investment bankers to evaluate capital adequacy. We calculate: (i) tangible common equity as total shareholders’ equity less goodwill and other intangible assets (excluding mortgage servicing rights); (ii) tangible assets as total assets less goodwill and other intangible assets; and (iii) tangible book value per share as tangible common equity divided by shares of common stock outstanding.

55

Our management, banking regulators, many financial analysts and other investors use these measures in conjunction with more traditional bank capital ratios to compare the capital adequacy of banking organizations with significant amounts of goodwill or other intangible assets, which typically stem from the use of the purchase accounting method of accounting for mergers and acquisitions. Tangible common equity, tangible assets, tangible book value per share and related measures should not be considered in isolation or as a substitute for total shareholders’ equity, total assets, book value per share or any other measure calculated in accordance with GAAP. Moreover, the manner in which we calculate tangible common equity, tangible assets, tangible book value per share and any other related measures may differ from that of other companies reporting measures with similar names. The following table reconciles shareholders’ equity (on a GAAP basis) to tangible common equity and total assets (on a GAAP basis) to tangible assets, and calculates our tangible book value per share:

(dollars in thousands)	March 31, 2018			December 31, 2017

Tangible common equity to tangible assets ratio		14.58	%		14.09	%
Tangible book value per share	$	15.01		$	14.70

Return on Average Tangible Common Equity. Management measures return on average tangible common equity (ROATCE) to assess the Company’s capital strength and business performance. Tangible equity excludes goodwill and other intangible assets (excluding mortgage servicing rights), and is reviewed by banking and financial institution regulators when assessing a financial institution’s capital adequacy. This non-GAAP financial measure should not be considered a substitute for operating results determined in accordance with GAAP and may not be comparable to other similarly titled measures used by other companies. The following table reconciles return on average tangible common equity to its most comparable GAAP measure:

Regulatory Reporting to Financial Statements

Some of the financial measures included in this prospectus differ from those reported on the FRB Y-9(c) report. These financial measures include “core deposits to total deposits” and “net non-core funding dependency ratio”. Our management uses these financial measures in its analysis of our performance.

56

Core Deposits to Total Deposits Ratio. The Bank measures core deposits by reviewing all relationships over $250,000 on a quarterly basis. We track all deposit relationships over $250,000 on a quarterly basis and consider a relationship to be core if there are any three or more of the following attributes: (i) relationships with us (as a director or shareholder); (ii) deposits within our market area; (iii) additional non-deposit services with us; (iv) electronic banking services with us; (v) active demand deposit account with us; (vi) deposits at market interest rates; and (vii) longevity of the relationship with us. We consider all deposit relationships under $250,000 as a core relationship except for time deposits originated through an internet service. This differs from the traditional definition of core deposits which is demand and savings deposits plus time deposits less than $250,000. As many of our customers have more than $250,000 on deposit with us, we believe that using this method reflects a more accurate assessment of our deposit base. The following table reconciles the adjusted core deposit to total deposits.

	As of			As of
(dollars in thousands)	March 31, 2018			December 31, 2017
Adjusted core deposit to total deposit ratio and net    non-core funding dependency ratio:

(1) Core deposits comprise all demand and savings deposits of any amount plus time deposits less than $250,000.

(2) Comprised of time deposits to core customers over $250,000 as defined in the lead-in to the table above.

(3) Comprised of internet and outside deposit originator time deposits less than $250,000 which are not considered to be core deposits.

(4) Comprised of demand and savings deposits in relationships over $250,000 which are considered non-core deposits because they do not satisfy the definition of core deposits set forth in the lead-in to the table above.

Management measures net non-core funding dependency ratio by using the data provided under “Core Deposits to Total Deposits Ratio” on page 54 to make adjustments to the traditional definition of net non-core funding dependency ratio. The traditional net non-core funding dependency ratio measures non-core funding sources less short term assets divided by total earning assets. The ratio indicates the dependency of the Company on non-core funding. The following table reconciles the adjusted net non-core dependency ratio.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk. Market risk represents the risk of loss due to changes in market values of assets and liabilities. We incur market risk in the normal course of business through exposures to market interest rates, equity prices, and credit spreads. We have identified two primary sources of market risk: interest rate risk and price risk.

Interest Rate Risk

Overview. Interest rate risk is the risk to earnings and value arising from changes in market interest rates. Interest rate risk arises from timing differences in the repricings and maturities of interest-earning assets and interest-bearing liabilities (repricing risk), changes in the expected maturities of assets and liabilities arising from embedded options, such as borrowers’ ability to prepay residential mortgage loans at any time and depositors’ ability to redeem certificates of deposit before maturity (option risk), changes in the shape of the yield curve where interest rates increase or decrease in a nonparallel fashion (yield curve risk), and changes in spread relationships between different yield curves, such as U.S. Treasuries and LIBOR (basis risk).

Our asset liability committee, or ALCO establishes broad policy limits with respect to interest rate risk. ALCO establishes specific operating guidelines within the parameters of the board of directors’ policies. In general, we seek to minimize the impact of changing interest rates on net interest income and the economic values of assets and liabilities. Our ALCO meets monthly to monitor the level of interest rate risk sensitivity to ensure compliance with the board of directors’ approved risk limits.

Interest rate risk management is an active process that encompasses monitoring loan and deposit flows complemented by investment and funding activities. Effective management of interest rate risk begins with understanding the dynamic characteristics of assets and liabilities and determining the appropriate interest rate risk posture given business forecasts, management objectives, market expectations, and policy constraints.

An asset sensitive position refers to a balance sheet position in which an increase in short-term interest rates is expected to generate higher net interest income, as rates earned on our interest-earning assets would reprice upward more quickly than rates paid on our interest-bearing liabilities, thus expanding our net interest margin.  Conversely, a liability sensitive position refers to a balance sheet position in which an increase in short-term interest rates is expected to generate lower net interest income, as rates paid on our interest-bearing liabilities would reprice upward more quickly than rates earned on our interest-earning assets, thus compressing our net interest margin.

Income Simulation and Economic Value Analysis. Interest rate risk measurement is calculated and reported to the board and ALCO at least quarterly. The information reported includes period-end results and identifies any policy limits exceeded, along with an assessment of the policy limit breach and the action plan and timeline for resolution, mitigation, or assumption of the risk.

We use two approaches to model interest rate risk: Net Interest Income at Risk, or NII at Risk, and Economic Value of Equity, or EVE. Under NII at Risk, net interest income is modeled utilizing various assumptions for assets, liabilities, and derivatives. EVE measures the period end market value of assets minus the market value of liabilities and the change in this value as rates change. EVE is a period end measurement.

	Net Interest Income Sensitivity
	Immediate Change in Rates
(dollars in thousands)	-100			+100			+200
March 31, 2018:
Dollar change	$	(714	)	$	4,802		$	9,516
Percent change		-1.14	%		7.65	%		15.15	%
December 31, 2017:
Dollar change		(1,664	)		4,805			9,659
Percent change		-2.60	%		7.52	%		15.11	%

We report NII at Risk to isolate the change in income related solely to interest earning assets and interest- bearing liabilities. The NII at Risk results included in the table above reflect the analysis used quarterly by management. It models gradual -100, +100 and +200 basis point parallel shifts in market interest rates, implied by the forward yield curve over the next one-year period. Due to the current low level of short-term interest rates, the analysis reflects a declining interest rate scenario of 100 basis points, the point at which many assets and liabilities reach zero percent.

59

We are within board policy limits for the +/-100 and +200 basis point scenarios. The NII at Risk reported at March 31, 2018, projects that our earnings are expected to be materially sensitive to changes in interest rates over the next year. In recent periods, the amount of fixed rate assets increased resulting in a position shift from slightly asset sensitive to asset sensitive.

	Economic Value of Equity Sensitivity (Shock)
	Immediate Change in Rates
(dollars in thousands)	-100			+100			+200
March 31, 2018:
Dollar change	$	(36,044	)	$	8,682		$	14,488
Percent change		-10.99	%		2.65	%		4.42	%
December 31, 2017:
Dollar change		(30,319	)		12,966			22,307
Percent change		-9.45	%		4.04	%		6.96	%

The EVE results included in the table above reflect the analysis used quarterly by management. It models immediate -100, +100 and +200 basis point parallel shifts in market interest rates. Due to the current low level of short-term interest rates, the analysis reflects a declining interest rate scenario of 100 basis points, the point at which many assets and liabilities reach zero percent.

We are within board policy limits for the +/-100 and +200 basis point scenarios. The EVE reported at March 31, 2018 projects that as interest rates increase immediately, the economic value of equity position will be expected to increase. When interest rates rise, fixed rate assets generally lose economic value; the longer the duration, the greater the value lost. The opposite is true when interest rates fall.

Price Risk. Price risk represents the risk of loss arising from adverse movements in the prices of financial instruments that are carried at fair value and subject to fair value accounting. We have price risk from our available for sale single-family residential mortgage loans and our fixed-rate available for sale securities.

Basis Risk. Basis risk represents the risk of loss arising from asset and liability pricing movements not changing in the same direction. We have basis risk in our single-family residential mortgage loan portfolio and our securities portfolio.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures. The Company’s management, including our President and Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of our “disclosure controls and procedures” (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of the end of the period covered by this report. Based on such evaluation, our President and Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures were effective.

Changes in internal control over financial reporting. There have not been any changes in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the fiscal quarter to which this report relates that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM1. LEGALPROCEEDINGS

There are no material pending legal proceedings, other than ordinary routine litigation incidental to our business. Management believes that none of the legal proceedings occurring in the ordinary course of business, individually or in the aggregate, will have a material adverse impact on the results of operations or financial condition of the Company.

ITEM1A. RISKFACTORS

The description of the risk factors associated with the Company’s business previously disclosed in Part I, Item 1A of our 2017 Annual Report is supplemented to include the following updated risk factor:

Existing and potential acquisitions may disrupt our business.

On April 23, 2018, we entered into a definitive agreement to acquire FAIC, the holding company of FAIB, a New York state-chartered bank with $873 billion in total assets as of December 31, 2017. That transaction is expected to close in the second half of 2018, subject to the receipt all required regulatory and shareholder approvals and the satisfaction or waiver, applicable, of all closing conditions.

The success of this merger will depend on, among other things, our ability to realize the anticipated revenue enhancements and efficiencies and to combine the businesses the Bank and FAIB, if the acquisition is completed, in a manner that does not materially disrupt the existing customer relationships of FAIB, or result in decreased revenues resulting from any loss of customers, and that permits growth opportunities to occur. If we are not able to successfully achieve these objectives, the anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected.

It is possible that the FAIC integration process when and if applicable, could result in the loss of key employees, the disruption of ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect our ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits of the mergers. Integration efforts could also divert management attention and resources. These integration matters could have an adverse effect on the combined company.

Existing and potential acquisitions may dilute stockholder value.

We are expected to issue approximately 3.0 million shares of our common stock in the FAIC acquisition.  Assuming our Registration Statement on Form S-4 registering the shares of our stock issuable to FAIC shareholders upon consummation of that acquisition is declared effective by the SEC, all of the shares of our common stock issued FAIC shareholders will be freely tradable without restrictions under the Securities Act, except for those shares issued to the two directors from FAIC.  If former FAIC shareholders sell substantial amounts of our common stock, it may cause the market price of our common stock to decrease.

We continue to evaluate merger and acquisition opportunities and conduct due diligence activities related to possible transactions with other financial institutions on an ongoing basis. As a result, merger or acquisition discussions and, in some cases, negotiations may take place and future mergers or acquisitions involving cash, debt or equity securities may occur at any time. Acquisitions typically involve the payment of a premium over book and market values, and, therefore, some dilution of our stock’s tangible book value and net income per common share may occur in connection with any future transaction. Furthermore, failure to realize the expected revenue increases, cost savings, increases in geographic or product presence, and/or other projected benefits from recent or future acquisitions could have a material adverse effect on our financial condition and results of operations.

We cannot say with any certainty that we will be able to consummate, or if consummated, successfully integrate our pending acquisition of FAIC or any future acquisitions or that we will not incur disruptions or unexpected expenses in integrating such acquisitions. In attempting to make such future acquisitions, we anticipate competing with other financial institutions, many of which have greater financial and operational resources. Acquiring other banks, businesses, or branches involves various risks commonly associated with acquisitions, including, among other things:

•Potential exposure to unknown or contingent liabilities of the target company;

•Exposure to potential asset quality issues of the target company;

61

•Potential disruption to our business;

•Potential diversion of management’s time and attention;

•The possible loss of key employees and customers of the target company;

•Difficulty in estimating the value of the target company; and

•Potential changes in banking or tax laws or regulations that may affect the target company.

Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

NOTE 1 - BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of RBB Bancorp and its wholly-owned subsidiaries Royal Business Bank (Bank) and RBB Asset Management Company (RAM), collectively referred to herein as "the Company", “we”, “our” or “us”.  All significant intercompany accounts and transactions have been eliminated in consolidation.  RBB Bancorp has no significant business activity other than its investments in Royal Business Bank and RAM.  

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. That, in the opinion of management, are necessary to reflect a fair presentation of financial results for the interim periods presented. The results of operations for the three months ended March 31, 2018 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 included in our Annual Report on Form 10-K for the year ended December 31, 2017 (the “2017 Annual Report”).

The Company accounts for its investments in its wholly owned special purpose TFC Statutory Trust under the equity method whereby the subsidiary's net earnings are recognized in the Company's statement of income.

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.  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 – Summary of Significant Policies in our consolidated financial statements included in our 2017 Annual Report.  

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606).  This Update requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services.  The following steps are applied in the updated guidance: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation.  These amendments are effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and one year later for nonpublic business entities.  Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that period. The Company plans to adopt ASU 2014-09 on January 1, 2019 utilizing the modified retrospective approach.  Since the guidance does not apply to revenue associated with financial instruments such as loans and investments, which are accounted for under other provisions of GAAP, we do not expect it to impact interest income, our largest component of income.  The Company will perform an overall assessment of revenue streams potentially affected by the ASU, including certain deposit related fees and interchange fees, to determine the impact this guidance will have on our consolidated financial statements.  

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10).  Changes made to the current measurement model primarily affect the accounting for equity securities and readily determinable fair values, where changes in fair value will impact earnings instead of other comprehensive income.  The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged.  The Update also changes the presentation and disclosure requirements for financial instruments including a requirement that public business entities use exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes.  This Update is generally effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years and one year later for nonpublic business entities.  Based upon an evaluation of the guidance in ASU 2016-01 the Company determined the ASU will not have a material impact on the Company’s consolidated financial statements as the accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged.  The Company adopted this ASU as of January 1, 2018 but will continue to monitor any updates to the guidance.  

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.  The amendments in this Update are effective for interim and annual periods beginning after December 15, 2018, for public business entities and one year later for all other entities.  The Company has several lease agreements which are currently considered operating leases and are therefore not included on the Company’s Consolidated Balance Sheets.  Under the new guidance the Company expects that some of the lease agreements will have to be recognized on the Consolidated Balance Sheets as a right-of-use asset with a corresponding lease liability.  Based upon a preliminary evaluation the Company expects that the ASU will have an impact on the Company’s Consolidated Balance Sheets.  The Company will continue to evaluate how extensive the impact will be under the ASU on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718.)  ASU 2016-09 includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements.  Under ASU 2016-09, excess tax benefits and certain tax deficiencies will no longer be recorded in additional paid-in capital (APIC).  Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement, and APIC pools will be eliminated.  In addition, the guidance requires excess tax benefits be presented as an operating activity on the statement of cash flows rather than as a financing activity.  ASU 2016-09 also permits an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards.  Forfeitures can be estimated, as required today, or recognized when they occur.  This guidance is effective for public business entities for interim and annual reporting periods beginning after December 15, 2016, and for nonpublic business entities annual reporting periods beginning after December 15, 2017, and interim periods within the reporting periods beginning after December 15, 2018.  Early adoption is permitted, but all of the guidance must be adopted in the same period.  The Company early adopted the ASU as of January 1, 2017. The Company plans to recognize forfeitures as they occur.  The early adoption of the ASU did not have a material effect on the company’s financial statements or disclosures.  

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instrument (Topic 326).  This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren't measured at fair value through net income.  In issuing the standard, the FASB is responding to criticism that today's guidance delays recognition of credit losses.  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.  The CECL model does not apply to available for sale (AFS) debt securities.  For 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.  As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today.  The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans.  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 No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019, for SEC filers, one year later for non SEC filing public business entities and annual reporting periods beginning after December 15, 2020, for nonpublic business entities and interim periods within the reporting periods beginning after December 15, 2021.  Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018.  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 No. 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 access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Topic 230). The new guidance clarifies the classification within the statement of cash flows for certain transactions, including debt extinguishment costs, zero-coupon debt, contingent consideration related to business combinations, insurance proceeds, equity method distributions and beneficial interests in securitizations. The guidance also clarifies that cash flows with aspects of multiple classes of cash flows that cannot be separated by source or use should be classified based on the activity that is likely to be the predominant source or use of cash flows for the item. This guidance is effective for fiscal years beginning after December 15, 2017 and will require application using a retrospective transition method. The Company adopted this statement as of January 1, 2018.  The Company believes the requirement to separately identify cash flows and application of the predominance principle is the cash flow item currently applicable to the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business (Topic 805). Currently, the ASU specifies three elements of a business – inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs, for example, by integrating the acquired set with their own inputs and processes. This led many transactions to be accounted for as business combinations rather than asset purchases under legacy GAAP. The primary goal of ASU 2017-01 is to narrow the definition of a business, and the guidance in this update provides a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this update should be applied prospectively on or after the effective date. The Company adopted this ASU on January 1, 2018 and will be applied prospectively for any future business combinations.

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350).  This ASU 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 the ASU, “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.”  ASU No. 2017-14 is effective for annual and any interim impairment tests performed in periods beginning after December 15, 2019 for public business entities that are SEC filers, December 15, 2020 for business entities that are not SEC filers, and December 15, 2021 for all other entities.  Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.   The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities (Subtopic 310-20), which is intended to enhance “the accounting for the amortization of premiums for purchased callable debt securities.” The ASU shortens the amortization period for certain callable debt securities purchased at a premium by requiring that the premium be amortized to the earliest call date. Under GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument.  The amendments in this Update affects all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The ASU’s amendments are effective for public business entities for interim and annual periods beginning after December 15, 2018. For other entities, the amendments are effective for annual periods beginning after December 15, 2019, and interim periods thereafter. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle.The implementation of the provisions of ASU No. 2017-08 will most likely not have a material impact the Company’s consolidated financial statements.The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation: Scope of codification Accounting (Topic 718). The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share- entity to apply modification accounting. An entity should account for the effects of a modification unless all the following are met: (1) The fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in ASU No. 2017-09 are effective for annual periods, and interim within those annual reporting periods, beginning after December 15, 2017; early adoption is permitted. The amendments in this ASU should be applied prospectively to an award modified on or after the adoption date. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements.

In July 2017, the FASB issued ASU 2017-13—Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments  (SEC Update).  At the July 20, 2017, EITF meeting, the SEC staff announced that it would not object when certain public business entities (PBEs) elect to use the non-PBE effective dates solely to adopt the FASB’s new standards on revenue (ASC 606) and leases (ASC 842). This ASU reflects comments made by the SEC. The Company will continue to evaluate how extensive the impact will be under the ASU on the Company’s consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02 – Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this Update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.  The amendments in this Update also require certain disclosures about stranded tax effects.  The amendments in this Update are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years.  Early adoption of the amendments in this Update is permitted, including adoption in any interim period, (1) for public business entities for reporting periods for which financial statements have not yet been issued and (2) for all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this Update should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized.  The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

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 at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation.  For securities in an unrealized loss position, management 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.

Loans and Allowance for Loan Losses

NOTE 3 - LOANS AND ALLOWANCE FOR LOAN LOSSES

The Company's loan portfolio consists primarily of loans to borrowers within Los Angeles, Ventura and Orange counties in California and Las Vegas (Clark County) in Nevada.  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 (TDRs) are considered impaired.  

The risk category of loans by class of loans was as follows at March 31, 2018 and December 31, 2017:

Loan Servicing [Abstract]

Loan Servicing

NOTE 4 - LOAN SERVICING

When mortgage and Small Business Administration (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.

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.

The principal balances of mortgage and SBA loans serviced for others at March 31, 2018 and December 31, 2017 are as follows:

	March 31,		December 31,

Goodwill and Intangibles

NOTE 5 - GOODWILL AND INTANGIBLES

Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date.  Goodwill resulting from whole bank acquisitions is not amortized, but tested for impairment at least annually.  The Company has selected December 31^st as the date to perform the annual impairment test.  Goodwill amounted to $29.9 million at March 31, 2018 and December 31, 2017, and is the only intangible asset with an indefinite life on the balance sheet.  There were no impairment losses recognized on goodwill during the three months ended March 31, 2018 and 2017.

Other intangible assets consist of core deposit intangible ("CDI") assets arising from whole bank acquisitions.   CDI assets are amortized on an accelerated method over their estimated useful life of 8 to 10 years.  CDI was recognized in the 2013 acquisition of Los Angeles National Bank and in the 2016 acquisition of TFC Holding Company.  The unamortized balance at March 31, 2018 and December 31, 2017 was $1,357,000 and $1,438,000, respectively, for both Los Angeles National Bank and TFC Holding Company.  CDI amortization expense was $81,000 and $94,000 for the three months ended March 31, 2018 and March 31, 2017, respectively, for both Los Angeles National Bank and TFC Holding Company.

Estimated CDI amortization expense for future years is as follows (dollars in thousands):

NOTE 7 - LONG-TERM DEBT

In March 2016, the Company issued $50 million of 6.5% fixed to floating rate subordinated debentures, due March 31, 2026. The interest rate is fixed through March 31, 2021 and floats at 3 month London Interbank Offered Rate (LIBOR) plus 516 basis points thereafter. The subordinated debt is considered Tier-2 capital at the Company. The Company allocated $35 million to the Bank as Tier-1 capital.

Subordinated Debentures

NOTE 8 - SUBORDINATED DEBENTURES

The Company, through the acquisition of TFC Bancorp, acquired TFC Statutory Trust (Trust).  The Trust contained a pooled private offering of 5,000 Trust preferred securities with a liquidation amount of $1,000 per security. TFC Bancorp issued $5,000,000 of subordinated debentures to the Trust in exchange for ownership of all of the common security 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 $3,255,000. There was a $1,900,000 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 amount of amortization expense recognized for the three months ended March 31, 2018 and 2017 was constant at $23,000.   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 Bank 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 1 capital (with certain limitations applicable) under current regulatory guidelines and interpretations. The subordinated debentures have a variable rate of interest equal to the three month LIBOR plus 1.65%, which was 3.77% and 3.24% at March 31, 2018 and December 31, 2017, respectively.

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 loan 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, 2018 and December 31, 2017, the Company had the following financial commitments whose contractual amount represents credit risk:

	March 31,		December 31,
(dollars in thousands)	2018		2017
Commitments to make loans	$	103,354	$	101,960
Unused lines of credit		119,964		99,217
Commercial and similar letters of credit		4,700		3,013
Standby letters of credit		1,575		1,575
	$	229,593	$	205,765

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 GAAP.  In the opinion of management, the disposition of such pending litigation will not have a material effect on the Company's financial statements.

Stock-based Compensation

NOTE 13 - STOCK-BASED COMPENSATION

RBB Bancorp 2017 Omnibus Stock Incentive Plan.

The 2017 Omnibus Stock Incentive Plan, or OSIP, was adopted by the Company’s board of directors on January 18, 2017 and approved by the Company’s shareholders at the Company’s annual meeting on May 23, 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 2017 OSIP, or 3,848,341 shares. This represents 24% of the issued and outstanding shares of the Company’s common stock as of March 31, 2018.  As of March 31, 2018, there were 1,353,207 shares of common stock available for issuance under the OSIP. 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.

RBB Bancorp 2010 Stock Option Plan

Under 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. After approval of the OSIP at the Company’s annual meeting on May 23, 2017, no additional grants will be made under the 2010 Plan.  The 2010 Plan has terminated and options that were granted under that 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.

The Company recognized stock-based compensation expense of $131,000 and recognized income tax benefits on that expense of $1.2 million for the three months ended March 31, 2018.  The Company recognized stock-based compensation expense of $198,000 and recognized income tax benefits on that expense of $61,000 for the three months ended March 31, 2017.

Regulated Operations [Abstract]

Regulatory Matters

NOTE 14 - REGULATORY MATTERS

Holding companies (with assets over $1 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 new 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 will be phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 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 to risk-weighted assets, and of Tier 1 capital to average assets.  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, at March 31, 2018 and December 31, 2017, that the Bank meets all capital adequacy requirements to which it is subject.

As defined in applicable regulations and set forth in the tables below, the Company 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 its 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 Bank has issued guidance which requires that they be consulted before payment of a dividend if a bank 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 Disclosures [Abstract]

Fair Value Measurements

NOTE 15 - 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 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 other real estate owned 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, 2018.

The following table provides the hierarchy and fair value for each major category of assets and liabilities measured at fair value at March 31, 2018 and December 31, 2017:

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

NOTE 16 - 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.

Fair value measurement and disclosure standards also establish a framework for measuring fair values. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability, in an orderly transaction between market participants on the measurement date. Further, the standards establish a fair value hierarchy that encourages an entity to maximize the use of observable inputs and limit the use of unobservable inputs when measuring fair values. The standards describe three levels of inputs that may be used to measure fair values:

•Level 1:  Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

•Level 2: Significant observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data.

•Level 3: Significant unobservable inputs that reflect a company's own assumptions about the factors that market participants would likely consider in pricing an asset or liability.

Fair value estimates are made at a specific point in time based on relevant market data and information about the financial instruments. The estimates incorporate our assumptions with regard to the impact of prepayments on future cash flows and credit quality adjustments based on risk characteristics of various financial instruments, among other things. The estimates are subjective and involve uncertainties and matters of significant judgment, and therefore cannot be determined with precision. Changes in assumptions could significantly alter the fair values presented.

The fair value hierarchy level and estimated fair value of significant financial instruments at March 31, 2018 and December 31, 2017 are summarized as follows:

NOTE 19 - RECENT DEVELOPMENTS

On April 18, 2018, RBB Bancorp declared a cash dividend of $0.09 per share for the first quarter of 2018.  The dividend is payable on May 15, 2018 to common shareholders of record as of April 30, 2018.

On April 23, 2018, RBB Bancorp and First American International Corporation, New York, New York (FAIC) entered into an Agreement and Plan of Merger (the Merger Agreement), providing for the merger of FAIC with and into RBB Bancorp, with RBB Bancorp as the surviving corporation (the Merger). Immediately following the effectiveness of the Merger, First American International Bank, a wholly-owned subsidiary of FAIC (FAIB) will be merged with and into the Bank, with the Bank being the surviving bank in the merger (the Bank Merger).

Pursuant to the terms and subject to the conditions of the Merger Agreement, at the effective time of the Merger (the Effective Time), each share of the common stock of FAIC will be convertible into the right to receive (i) 1.3472 shares of the common stock, no par value per share, of RBB Bancorp and (ii) $15.30 in cash (such consideration set forth in clauses (i) and (ii), the Per Share Merger Consideration).  Holders of in-the-money FAIC stock options (FAIC Stock Options) will receive an amount equal to (1) $51.00 minus (2) the exercise price per share with respect to the corresponding FAIC Stock Option.

Pursuant to the terms of the Merger Agreement, RBB Bancorp and FAIC have agreed that FAIC will repurchase its currently outstanding $17 million of preferred stock held by the U.S. Department of the Treasury and issued under the Troubled Asset Relief Program prior to completion of the Merger (the TARP Redemption) and that the Bank will assist in financing such repurchase, if necessary.  Royal Business Bank has committed to lend FAIC $17 million for up to one month, if necessary.

The Merger is expected to close in the second half of 2018, subject to the satisfaction of customary closing conditions, including regulatory approvals and approval of FAIC’s shareholders.  Each director of FAIC has entered into an agreement with RBB Bancorp pursuant to which they have committed to vote their shares of FAIC common stock in favor of the proposed acquisition.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606).  This Update requires an entity to recognize revenue as performance obligations are met, in order to reflect the transfer of promised goods or services to customers in an amount that reflects the consideration the entity is entitled to receive for those goods or services.  The following steps are applied in the updated guidance: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the entity satisfies a performance obligation.  These amendments are effective for public business entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period and one year later for nonpublic business entities.  Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that period. The Company plans to adopt ASU 2014-09 on January 1, 2019 utilizing the modified retrospective approach.  Since the guidance does not apply to revenue associated with financial instruments such as loans and investments, which are accounted for under other provisions of GAAP, we do not expect it to impact interest income, our largest component of income.  The Company will perform an overall assessment of revenue streams potentially affected by the ASU, including certain deposit related fees and interchange fees, to determine the impact this guidance will have on our consolidated financial statements.  

In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10).  Changes made to the current measurement model primarily affect the accounting for equity securities and readily determinable fair values, where changes in fair value will impact earnings instead of other comprehensive income.  The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged.  The Update also changes the presentation and disclosure requirements for financial instruments including a requirement that public business entities use exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes.  This Update is generally effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years and one year later for nonpublic business entities.  Based upon an evaluation of the guidance in ASU 2016-01 the Company determined the ASU will not have a material impact on the Company’s consolidated financial statements as the accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged.  The Company adopted this ASU as of January 1, 2018 but will continue to monitor any updates to the guidance.  

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.  The amendments in this Update are effective for interim and annual periods beginning after December 15, 2018, for public business entities and one year later for all other entities.  The Company has several lease agreements which are currently considered operating leases and are therefore not included on the Company’s Consolidated Balance Sheets.  Under the new guidance the Company expects that some of the lease agreements will have to be recognized on the Consolidated Balance Sheets as a right-of-use asset with a corresponding lease liability.  Based upon a preliminary evaluation the Company expects that the ASU will have an impact on the Company’s Consolidated Balance Sheets.  The Company will continue to evaluate how extensive the impact will be under the ASU on the Company’s consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718.)  ASU 2016-09 includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements.  Under ASU 2016-09, excess tax benefits and certain tax deficiencies will no longer be recorded in additional paid-in capital (APIC).  Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement, and APIC pools will be eliminated.  In addition, the guidance requires excess tax benefits be presented as an operating activity on the statement of cash flows rather than as a financing activity.  ASU 2016-09 also permits an accounting policy election for the impact of forfeitures on the recognition of expense for share-based payment awards.  Forfeitures can be estimated, as required today, or recognized when they occur.  This guidance is effective for public business entities for interim and annual reporting periods beginning after December 15, 2016, and for nonpublic business entities annual reporting periods beginning after December 15, 2017, and interim periods within the reporting periods beginning after December 15, 2018.  Early adoption is permitted, but all of the guidance must be adopted in the same period.  The Company early adopted the ASU as of January 1, 2017. The Company plans to recognize forfeitures as they occur.  The early adoption of the ASU did not have a material effect on the company’s financial statements or disclosures.  

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instrument (Topic 326).  This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren't measured at fair value through net income.  In issuing the standard, the FASB is responding to criticism that today's guidance delays recognition of credit losses.  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.  The CECL model does not apply to available for sale (AFS) debt securities.  For 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.  As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today.  The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans.  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 No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019, for SEC filers, one year later for non SEC filing public business entities and annual reporting periods beginning after December 15, 2020, for nonpublic business entities and interim periods within the reporting periods beginning after December 15, 2021.  Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018.  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 No. 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 access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (Topic 230). The new guidance clarifies the classification within the statement of cash flows for certain transactions, including debt extinguishment costs, zero-coupon debt, contingent consideration related to business combinations, insurance proceeds, equity method distributions and beneficial interests in securitizations. The guidance also clarifies that cash flows with aspects of multiple classes of cash flows that cannot be separated by source or use should be classified based on the activity that is likely to be the predominant source or use of cash flows for the item. This guidance is effective for fiscal years beginning after December 15, 2017 and will require application using a retrospective transition method. The Company adopted this statement as of January 1, 2018.  The Company believes the requirement to separately identify cash flows and application of the predominance principle is the cash flow item currently applicable to the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business (Topic 805). Currently, the ASU specifies three elements of a business – inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs, for example, by integrating the acquired set with their own inputs and processes. This led many transactions to be accounted for as business combinations rather than asset purchases under legacy GAAP. The primary goal of ASU 2017-01 is to narrow the definition of a business, and the guidance in this update provides a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this update should be applied prospectively on or after the effective date. The Company adopted this ASU on January 1, 2018 and will be applied prospectively for any future business combinations.

In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350).  This ASU 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 the ASU, “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.”  ASU No. 2017-14 is effective for annual and any interim impairment tests performed in periods beginning after December 15, 2019 for public business entities that are SEC filers, December 15, 2020 for business entities that are not SEC filers, and December 15, 2021 for all other entities.  Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.   The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs: Premium Amortization on Purchased Callable Debt Securities (Subtopic 310-20), which is intended to enhance “the accounting for the amortization of premiums for purchased callable debt securities.” The ASU shortens the amortization period for certain callable debt securities purchased at a premium by requiring that the premium be amortized to the earliest call date. Under GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument.  The amendments in this Update affects all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date (that is, at a premium). The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The ASU’s amendments are effective for public business entities for interim and annual periods beginning after December 15, 2018. For other entities, the amendments are effective for annual periods beginning after December 15, 2019, and interim periods thereafter. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle.The implementation of the provisions of ASU No. 2017-08 will most likely not have a material impact the Company’s consolidated financial statements.The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation – Stock Compensation: Scope of codification Accounting (Topic 718). The amendments in ASU 2017-09 provide guidance about which changes to the terms or conditions of a share- entity to apply modification accounting. An entity should account for the effects of a modification unless all the following are met: (1) The fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification; (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in ASU No. 2017-09 are effective for annual periods, and interim within those annual reporting periods, beginning after December 15, 2017; early adoption is permitted. The amendments in this ASU should be applied prospectively to an award modified on or after the adoption date. The Company does not expect this ASU to have a material impact on the Company’s consolidated financial statements.

In July 2017, the FASB issued ASU 2017-13—Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842): Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments  (SEC Update).  At the July 20, 2017, EITF meeting, the SEC staff announced that it would not object when certain public business entities (PBEs) elect to use the non-PBE effective dates solely to adopt the FASB’s new standards on revenue (ASC 606) and leases (ASC 842). This ASU reflects comments made by the SEC. The Company will continue to evaluate how extensive the impact will be under the ASU on the Company’s consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02 – Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this Update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. Consequently, the amendments eliminate the stranded tax effects resulting from the Tax Cuts and Jobs Act and will improve the usefulness of information reported to financial statement users. However, because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the underlying guidance that requires that the effect of a change in tax laws or rates be included in income from continuing operations is not affected.  The amendments in this Update also require certain disclosures about stranded tax effects.  The amendments in this Update are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years.  Early adoption of the amendments in this Update is permitted, including adoption in any interim period, (1) for public business entities for reporting periods for which financial statements have not yet been issued and (2) for all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments in this Update should be applied either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized.  The Company will continue to access the potential impact that this ASU will have on the Company’s consolidated financial statements.
