Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The consolidated financial statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).
Use of Estimates	Use of Estimates: To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.
Concentration of Risk	Concentration of Risk: Most of the Company’s customers are located within Los Angeles County and the surrounding area. The concentration of loans originated in this area may subject the Company to the risk of adverse impacts of economic, regulatory or other developments that could occur in Southern California. The Company has significant concentration in commercial real estate loans. The Company obtains what it believes to be sufficient collateral to secure potential losses. The extent and value of the collateral obtained varies based upon the details underlying each loan agreement.
Cash Flows	Cash Flows: Cash and cash equivalents include cash, deposits with other financial institutions with original maturities less than 90 days, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions.
Securities	Securities: Securities are classified as held to maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Securities are classified as available-for-sale when they might be sold before maturity. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Securities available for sale are measured at fair value and are subject to impairment testing. For securities available for sale in an unrealized loss position, management evaluates whether the decline in fair value has resulted in from a credit-related loss or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. Management (1) recognizes an allowance for credit losses by a charge to earnings for the credit-related component of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components of the fair value decline. If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation reserve would be reduced, but not more than the amount of the current existing reserve for that security.
Other investments	Other investments: Other investments includes the followings : (i) Federal Home Loan Bank (“FHLB”) Stock - the Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income; (ii) Pacific Coast Bankers Bank (“PCBB”) Stock - the Bank is a member of PCBB. PCBB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income; and (iii) the Company’s investment in a mutual fund to satisfy the Company’s requirements under the Community Reinvestment Act (“CRA”). CRA mutual fund is reported at fair value. Unrealized gains and losses on a CRA fund are recognized in other income in the Consolidated Statements of Income.
Loans Held for Sale	Loans Held for Sale: Certain Small Business Administration (“SBA”) loans that may be sold prior to maturity are designated as held for sale at origination and are recorded at the lower of their cost or fair value less costs to sell, determined on an aggregate basis. A valuation allowance is established if the market value of such loans is lower than their cost, and operations are charged or credited for valuation adjustments. Origination fees on loans held for sale, net of certain costs of processing and closing the loans, are deferred until the time of sale and are included in the computation of the gain or loss from the sales of the related loans. A portion of the premium on sale of SBA loans is recognized as gains on sales of loans at the time of the sale. These loans are generally sold with servicing retained.
Loans Receivable and Allowance for Credit Losses	Loans Receivable: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs and an allowance for credit losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. The recorded investment in loans includes accrued interest receivable, deferred loan fees and costs, and unearned income. The accrual of interest income on commercial real estate and other commercial and industrial loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer loans are typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for Credit Losses: The Company employs a modeled approach that takes into account current and future economic conditions to estimate lifetime expected losses on a collective basis. With the adoption of Current Expected Credit Losses, the Company elected not to consider accrued interest receivable in its estimated credit losses because the Company writes off uncollectible accrued interest receivable in a timely manner. The Company considers writing off accrued interest amounts once the amounts become 90 days past due to be considered within a timely manner. The Company has elected to write off accrued interest receivable by reversing interest income. The Company uses transition matrices to develop the Probability of Default ("PD") and Loss Given Default ("LGD") approach, incorporating quantitative factors and qualitative considerations in the calculation of the allowance for credit losses for collectively assessed loans. The model provides forecasts of PD and LGD based on national unemployment rates using regression analysis. The Company incorporates future economic conditions using a weighted multiple scenario approach: baseline and adverse. The Company applies a reasonable and supportable period of one year for the baseline scenario and two years for the adverse scenario, after which loss assumptions revert to historical loss information through a one-year reversion period for the baseline scenario and a two-year reversion period for the adverse scenario. Additionally, the Company aggregated loan portfolio based on similar risk characteristic. The Company elected to use the Call Report codes and loan risk ratings for loan segmentation in allowance for credit losses. The Company used the following assumptions in a sensitivity analysis of our allowance for credit losses: unemployment rate forecast based on supervisory severely adverse scenario, 0% prepayment rates, loan risk grade changes of commercial real estate and commercial and industrial loan portfolio in worst case scenario based on the Company history, and applying a 100% weighting to severely adverse scenario. The analysis demonstrates the sensitivity to the allowance for credit losses to key quantitative assumptions and it is not intended to estimate changes in the overall allowance for credit losses and it does not capture all the potential unknown variables that could arise in the forecast period, but it provides an approximation of a possible outcome under hypothetical severe conditions. In order to quantify the credit risk impact of other trends and changes within the loan portfolio, the Company utilizes qualitative adjustments to the modeled estimated loss approaches. Included in the qualitative portion of our analysis of the allowance for credit losses are key inputs including GDP, unemployment rates, interest rates, asset quality ratios, loan portfolio concentration, California house price index and commercial real estate price index. The parameters for making adjustments are established under a Credit Risk Matrix that provides different possible scenarios for each of the factors listed below. The Credit Risk Matrix and the possible scenarios enable the Bank to qualitatively adjust the loss rates. This matrix considers the following nine factors, which are patterned after the guidelines provided under the Federal Financial Institutions Examination Council Interagency Policy Statement on the Allowance for Credit Losses, updated to reflect the adoption of Current Expected Credit Losses: • Changes in lending policies and procedures, including changes in underwriting standards and practices for collection, charge-offs, and recoveries; • Actual and expected changes in national and local economic and business conditions and developments in which the institution operates that affect the collectivity of loans; • Changes in the nature and volume of the loan portfolio; • Changes in the experience, ability, and depth of lending management and staff; • Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified loans; • Changes in the quality of the credit review function; • Changes in the value of the underlying collateral for loans that are not collateral-dependent; • The existence, growth, and effect of any concentrations of credit, and • The effect of other external factors, such as the regulatory, legal and technological environments; competition; and events such as natural disasters. The Company segments loans primarily by Call Report codes (collateral type) and loan risk ratings, considering that the same type of loans share considerable similar risk characteristics. For loans that do not share similar risk characteristics such as nonaccrual loans above $500 thousand, the Company evaluates these loans on an individual basis in accordance with ASC 326. Such nonaccrual loans are considered to have different risk profiles than performing loans and are therefore evaluated individually. The Company elected to collectively assess nonaccrual loans with balances below $500 thousand along with the performing and accrual loans, in order to reduce the operational burden of individually assessing small nonaccrual loans with immaterial balances. For individually assessed loans, the allowance for credit losses is measured using either 1) the present value of future cash flows discounted at the loan’s effective interest rate; or 2) the fair value of the collateral, if the loan is collateral-dependent. For the collateral-dependent loans, the Company obtains a new appraisal to determine the fair value of collateral. The appraisals are based on an “as-is” valuation. To ensure that appraised values remain current, the Company obtains updated appraisals every twelve months from a qualified independent appraiser. If the fair value of the collateral is less than the amortized balance of the loan, the Company recognizes an allowance for credit losses with a corresponding charge to the provision for credit losses. The Company maintains a separate allowance for credit losses for its off-balance sheet commitments. The Company uses an estimated funding rate to allocate an allowance to undrawn exposures. This funding rate is used as a credit conversion factor to capture how much undrawn lines of credit can potentially become drawn at any point. The funding rate is determined based on a look-back period of 8 quarters. Credit loss is not estimated for off-balance sheet commitments that are unconditionally cancellable by the Company.
Servicing Assets	Servicing Assets: When SBA loans are sold with servicing retained, servicing assets 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. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, prepayment speeds, and default rates and losses. The Company compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. Servicing assets are subsequently measured using the amortization method which requires servicing assets 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 assets are evaluated for impairment based upon the fair value of the assets as compared to their carrying amount. Impairment is recognized through a valuation allowance 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, a reduction of the valuation allowance may be recorded as an increase to income. Changes in the valuation allowances are reported with other income on the income statement. The fair values of servicing rights are subject to fluctuations as a result of changes in estimated and actual prepayment speeds, default rates, and losses. Servicing fee income, which is reported on the income statement as other income, is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal and are recorded as income when earned. The amortization of servicing assets is netted against loan servicing fee income. Late fees and ancillary fees related to loan servicing are not material.
Company Owned Life Insurance	Company Owned Life Insurance: The Company has purchased life insurance policies on certain key executives. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Transfers of Financial Assets	Transfers of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Premises and Equipment	Premises and Equipment: Premises and equipment are stated at cost, less accumulated depreciation. Equipment and furnishings are depreciated over 3 to 10 years, and leasehold improvements are amortized over the lesser of the terms of the respective leases or the estimated useful lives. The straight-line method of depreciation is used for financial reporting purposes. Repairs and maintenance are charged to operating expenses as incurred.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments: Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.
Low Income Housing Partnership Investments	Low Income Housing Partnership Investments: The Company records the low income housing partnership investments, net of amortization, using the proportional amortization method and the Company reports it to other assets on the Consolidated Balance Sheets. The Company recognizes tax credits in income tax expense on the Consolidated Statement of Income. The commitments to fund the low income housing partnership investments are also recorded and included to other liabilities on the Consolidated Balance Sheets. The Company utilizes the year to date tax credits on the Company’s income tax returns for the year.
Stock-Based Compensation	Stock-Based Compensation: Compensation cost is recognized for stock options and restricted stock awards issued to employees based on the fair value of the awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of the grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.
Earnings per Common Share	Earnings per Common Share: Basic and diluted earnings per share is based on the two-class method prescribed in ASC Topic 260, Earnings Per Share (ASC 260). Stock options and restricted stock awards are considered outstanding for this calculation unless unearned. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock-based compensation plans. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.
Income Taxes	Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.
Comprehensive Income	Comprehensive Income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on available-for-sale ("AFS") debt securities, which are also recognized as separate components of shareholders’ equity, net of tax.
Loss Contingencies	Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.
Fair Value of Financial Instruments	Fair Value of Financial Instruments: Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 13—Fair Value of Financial Instruments. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Operating Segments	Operating Segments: While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Discrete financial information is not available other than on a Company-wide basis.
New Accounting Pronouncements Adopted and Recently Issued Accounting Pronouncements under Evaluation	New Accounting Pronouncements Adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The Company adopted ASU 2016-13 using a modified retrospective approach on January 1, 2023 without electing the fair value option on eligible financial instruments under ASU 2019-05. The Company replaced the current incurred loss accounting model with the Current Expected Credit Losses ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. ("ASU 2022-02"). ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in Accounting Standards Codification (“ASC”) Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, ASU 2022-02 requires entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. The Company adopted ASU 2022-02 on January 1, 2023, and the adoption of ASU 2022-02 did not have a significant impact on its consolidated financial statements. In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. This ASU permits reporting entities to elect to account for tax equity investments, regardless of the tax credit program for which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense. A reporting entity makes an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments. The Company adopted ASU 2023-02 on January 1, 2024, and the adoption did not have a material impact on its consolidated financial statements. Recently Issued Accounting Pronouncement under Evaluation In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU amends the disclosure requirements for income taxes, including the requirement for further disaggregation of the income tax rate reconciliation and income taxes paid disclosures. The amendments in this guidance must be applied prospectively, with the option to apply retrospectively. This guidance is effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements. Loan Modifications to Borrowers Experiencing Financial Difficult: On January 1, 2023, the Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures”, which eliminated the accounting guidance for troubled debt restructurings (“TDRs”) while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. Upon adoption of this guidance, the Company no longer establishes a specific reserve for modifications to borrowers experiencing financial difficulty, unless those loans do not share the same risk characteristics with other loans in the portfolio. Provided that is not the case, these modifications are included in their respective cohort and the allowance for credit losses is estimated on a pooled basis consistent with the other loans with similar risk characteristics. Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, other than insignificant payment deferrals, other than insignificant term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral.

Basis of Presentation: The consolidated financial statements of the Company have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”).

Use of Estimates

Use of Estimates: To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.

Concentration of Risk

Concentration of Risk: Most of the Company’s customers are located within Los Angeles County and the surrounding area. The concentration of loans originated in this area may subject the Company to the risk of adverse impacts of economic, regulatory or other developments that could occur in Southern California. The Company has significant concentration in commercial real estate loans. The Company obtains what it believes to be sufficient collateral to secure potential losses. The extent and value of the collateral obtained varies based upon the details underlying each loan agreement.

Cash Flows

Cash Flows: Cash and cash equivalents include cash, deposits with other financial institutions with original maturities less than 90 days, and federal funds sold. Net cash flows are reported for customer loan and deposit transactions.

Securities

Securities: Securities are classified as held to maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Securities are classified as available-for-sale when they might be sold before maturity. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

Securities available for sale are measured at fair value and are subject to impairment testing. For securities available for sale in an unrealized loss position, management evaluates whether the decline in fair value has resulted in from a credit-related loss or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. Management (1) recognizes an allowance for credit losses by a charge to earnings for the credit-related component of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components of the fair value decline. If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation reserve would be reduced, but not more than the amount of the current existing reserve for that security.

Other investments

Other investments: Other investments includes the followings : (i) Federal Home Loan Bank (“FHLB”) Stock - the Bank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income; (ii) Pacific Coast Bankers Bank (“PCBB”) Stock - the Bank is a member of PCBB. PCBB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income; and (iii) the Company’s investment in a mutual fund to satisfy the Company’s requirements under the Community Reinvestment Act (“CRA”). CRA mutual fund is reported at fair value. Unrealized gains and losses on a CRA fund are recognized in other income in the Consolidated Statements of Income.

Loans Held for Sale

Loans Held for Sale: Certain Small Business Administration (“SBA”) loans that may be sold prior to maturity are designated as held for sale at origination and are recorded at the lower of their cost or fair value less costs to sell, determined on an aggregate basis. A valuation allowance is established if the market value of such loans is lower than their cost, and operations are charged or credited for valuation adjustments. Origination fees on loans held for sale, net of certain costs of processing and closing the loans, are deferred until the time of sale and are included in the computation of the gain or loss from the sales of the related loans. A portion of the premium on sale of SBA loans is recognized as gains on sales of loans at the time of the sale. These loans are generally sold with servicing retained.

Loans Receivable and Allowance for Credit Losses

Loans Receivable: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, net of deferred loan fees and costs and an allowance for credit losses. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level-yield method without anticipating prepayments. The recorded investment in loans includes accrued interest receivable, deferred loan fees and costs, and unearned income.

The accrual of interest income on commercial real estate and other commercial and industrial loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Consumer loans are typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans.

All interest accrued but not received for loans placed on nonaccrual status is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Additionally, the Company aggregated loan portfolio based on similar risk characteristic. The Company elected to use the Call Report codes and loan risk ratings for loan segmentation in allowance for credit losses.

The Company used the following assumptions in a sensitivity analysis of our allowance for credit losses: unemployment rate forecast based on supervisory severely adverse scenario, 0% prepayment rates, loan risk grade changes of commercial real estate and commercial and industrial loan portfolio in worst case scenario based on the Company history, and applying a 100% weighting to severely adverse scenario.

In order to quantify the credit risk impact of other trends and changes within the loan portfolio, the Company utilizes qualitative adjustments to the modeled estimated loss approaches. Included in the qualitative portion of our analysis of the allowance for credit losses are key inputs including GDP, unemployment rates, interest rates, asset quality ratios, loan portfolio concentration, California house price index and commercial real estate price index. The parameters for making adjustments are established under a Credit Risk Matrix that provides different possible scenarios for each of the factors listed below. The Credit Risk Matrix and the possible scenarios enable the Bank to qualitatively adjust the loss rates. This matrix considers the following nine factors, which are patterned after the guidelines provided under the Federal

Financial Institutions Examination Council Interagency Policy Statement on the Allowance for Credit Losses, updated to reflect the adoption of Current Expected Credit Losses:

• Changes in lending policies and procedures, including changes in underwriting standards and practices for collection, charge-offs, and recoveries;

• Actual and expected changes in national and local economic and business conditions and developments in which the institution operates that affect the collectivity of loans;

• Changes in the nature and volume of the loan portfolio;

• Changes in the experience, ability, and depth of lending management and staff;

• Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified loans;

• Changes in the quality of the credit review function;

• Changes in the value of the underlying collateral for loans that are not collateral-dependent;

• The existence, growth, and effect of any concentrations of credit, and

• The effect of other external factors, such as the regulatory, legal and technological environments; competition; and events such as natural disasters.

The Company segments loans primarily by Call Report codes (collateral type) and loan risk ratings, considering that the same type of loans share considerable similar risk characteristics. For loans that do not share similar risk characteristics such as nonaccrual loans above $500 thousand, the Company evaluates these loans on an individual basis in accordance with ASC 326.

Company Owned Life Insurance: The Company has purchased life insurance policies on certain key executives. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.

Transfers of Financial Assets

Transfers of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

Premises and Equipment

Premises and Equipment: Premises and equipment are stated at cost, less accumulated depreciation. Equipment and furnishings are depreciated over 3 to 10 years, and leasehold improvements are amortized over the lesser of the terms of the respective leases or the estimated useful lives. The straight-line method of depreciation is used for financial reporting purposes. Repairs and maintenance are charged to operating expenses as incurred.

Loan Commitments and Related Financial Instruments

Loan Commitments and Related Financial Instruments: Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded.

Low Income Housing Partnership Investments

Low Income Housing Partnership Investments: The Company records the low income housing partnership investments, net of amortization, using the proportional amortization method and the Company reports it to other assets on the Consolidated Balance Sheets. The Company recognizes tax credits in income tax expense on the Consolidated Statement of Income. The commitments to fund the low income housing partnership investments are also recorded and included to other liabilities on the Consolidated Balance Sheets. The Company utilizes the year to date tax credits on the Company’s income tax returns for the year.

Stock-Based Compensation

Stock-Based Compensation: Compensation cost is recognized for stock options and restricted stock awards issued to employees based on the fair value of the awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of the grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.

Earnings per Common Share

Earnings per Common Share: Basic and diluted earnings per share is based on the two-class method prescribed in ASC Topic 260, Earnings Per Share (ASC 260). Stock options and restricted stock awards are considered outstanding for this calculation unless unearned. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock-based compensation plans. Earnings and dividends per share are restated for all stock splits and stock dividends through the date of issuance of the financial statements.

Income Taxes

Income Taxes: Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.

A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded.

Comprehensive Income

Comprehensive Income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on available-for-sale ("AFS") debt securities, which are also recognized as separate components of shareholders’ equity, net of tax.

Loss Contingencies

Loss Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.

Fair Value of Financial Instruments

Fair Value of Financial Instruments: Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 13—Fair Value of Financial Instruments. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.

Operating Segments

Operating Segments: While the chief decision-makers monitor the revenue streams of the various products and services, operations are managed and financial performance is evaluated on a Company-wide basis. Discrete financial information is not available other than on a Company-wide basis.

New Accounting Pronouncements Adopted and Recently Issued Accounting Pronouncements under Evaluation

New Accounting Pronouncements Adopted

Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The Company adopted ASU 2016-13 using a modified retrospective approach on January 1, 2023 without electing the fair value option on eligible financial instruments under ASU 2019-05. The Company replaced the current incurred loss accounting model with the Current Expected Credit Losses ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts.

FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. ("ASU 2022-02"). ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in Accounting Standards Codification (“ASC”) Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, ASU 2022-02 requires entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. The Company adopted ASU 2022-02 on January 1, 2023, and the adoption of ASU 2022-02 did not have a significant impact on its consolidated financial statements.

In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. This ASU permits reporting entities to elect to account for tax equity investments, regardless of the tax credit program for which the income tax credits are received, using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the income tax credits and other income tax benefits received and recognizes the net amortization and income tax credits and other income tax benefits in the income statement as a component of income tax expense. A reporting entity makes an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments. The Company adopted ASU 2023-02 on January 1, 2024, and the adoption did not have a material impact on its consolidated financial statements.

Recently Issued Accounting Pronouncement under Evaluation

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU amends the disclosure requirements for income taxes, including the requirement for further disaggregation of the income tax rate reconciliation and income taxes paid disclosures. The amendments in this guidance must be applied prospectively, with the option to apply retrospectively. This guidance is effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of this new standard on its consolidated financial statements and the adoption is not expected to have a significant impact on the consolidated financial statements.

Loan Modifications to Borrowers Experiencing Financial Difficult: On January 1, 2023, the Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures”, which eliminated the accounting guidance for troubled debt restructurings (“TDRs”) while enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. This guidance was applied on a prospective basis. Upon adoption of this guidance, the Company no longer establishes a specific reserve for modifications to borrowers experiencing financial difficulty, unless those loans do not share the same risk characteristics with other loans in the portfolio. Provided that is not the case, these modifications are included in their respective cohort and the allowance for credit losses is estimated on a pooled basis consistent with the other loans with similar risk characteristics.

Modifications to borrowers experiencing financial difficulty may include interest rate reductions, principal or interest forgiveness, other than insignificant payment deferrals, other than insignificant term extensions, and other actions intended to minimize economic loss and to avoid foreclosure or repossession of collateral.
