Organization Consolidation And Presentation Of Financial Statements [Abstract]
Business Description	Note 1. Business Description OP Bancorp (the “Company”) is a California corporation whose common stock is quoted on the Nasdaq Global Market under the ticker symbol, “OPBK.” The Company was formed to acquire 100% of the voting equity of Open Bank (the “Bank”) and commenced operation as a bank holding company on June 1, 2016. This transaction was treated as an internal reorganization as all shareholders of the Bank became shareholders of the Company. The Company has no operations other than ownership of the Bank. The Bank is a California state-chartered and FDIC-insured financial institution, which began its operations on June 10, 2005. Headquartered in downtown Los Angeles, California, the Company operates primarily in the traditional banking business arena that includes accepting deposits and making loans and investments. The Company’s primary deposit products are demand and time deposits, and the primary lending products are commercial business loans to small to medium sized businesses. The Company is operating with nine full service branches, eight of which are located in California, in Downtown Los Angeles, Los Angeles Fashion District, Los Angeles Koreatown, Gardena, Buena Park and Santa Clara. The Company opened a ninth full service branch in Carrollton, Texas in April, 2019. The Company also has four loan production offices in Atlanta, Georgia, Aurora, Colorado, and Lynwood and Seattle, Washington . On March 27, 2018, the Company completed its initial public offering of common stock, pursuant to which an aggregate of 2,300,000 shares of its common stock were sold at a public offering price of $11.00 per share, for aggregate net proceeds of approximately $22.6 million, after deducting underwriter discounts and commissions paid by it of approximately $1.7 million and other offering expenses of approximately $925,000.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation: The accompanying unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-Q and conform to practices within the banking industry and include all of the information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results for the full year. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2018, included in the Companys’ Annual Report on Form 10-K for the year ended December 31, 2018. 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: 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 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 and Federal Home Loan Bank advances transactions. 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. 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. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement, and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. 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 are recognized in other income in the Consolidated Statements of Income and Comprehensive Income. 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: 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 loan 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 Loan Losses: The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that in management’s judgment should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is 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. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial real estate and construction loans. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Income recognition on impaired loans materially conforms to the method the Company uses for income recognition on nonaccrual loans. Allowance for impaired loans is determined based on the present value of the estimated cash flows or on the fair value of the collateral if the loan is collateral dependent, less costs to sell. If the measured fair value is less than the recorded investment in the loan, the deficiency will be charged off against the allowance for loan losses, or alternatively, a specific allocation will be established. For consumer loans, management will generally charge off the balance if the loan is 90 days or more past due. The general component of the allowance covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent two years. For those portfolio segments that the Company does not have sufficient historical data available to track the loss migration, the loss factors are based on the actual loss history experienced by the Company over the most recent five years. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified in the Company’s loan portfolio, and are also representative of the classes within the portfolio: commercial real estate, SBA loans—real estate, SBA loans—non-real estate, commercial and industrial, home mortgage, and consumer. The Company reviews the credit risk exposure of all its portfolio segments by internally assigned grades. The Company categorizes loans into risk grades based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. For the home mortgage and consumer portfolio segments, the Company’s primary monitoring tool is reviewing past due listings to determine if the loans are performing. The determination of the allowance for loan losses is based on estimates that are particularly susceptible to changes in the economic environment and market conditions. Management believes that as of June 30, 2019 and December 31, 2018 the allowance for loan losses is adequate based on information currently available. If a deterioration in the economy of the Company’s principal market area occurs, the Company’s loan portfolios could be adversely impacted and higher charge-offs and increases in non-performing assets could result. Such an adverse impact could also require a larger allowance for loan losses. 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: 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 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 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. Other Real Estate Owned, Net: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when the legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through the completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at the lower of their cost or fair value less estimated costs to sell. If their fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed. 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. 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: 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 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. The Company does not expect the total amount of unrecognized tax benefits to significantly increase or decrease in the next twelve months. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. There were no interest or penalties recognized in the three and six months ended June 30, 2019 or 2018. Comprehensive Income/(Loss): Comprehensive income/(loss) consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, which are also recognized as separate components of shareholders’ equity, net of tax. 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 values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 15—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: 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. Reclassifications: Some items in the prior period financial statements were reclassified to conform to the current presentation. Reclassification had no effect on prior year net income or shareholders’ equity. Recent Accounting Pronouncements: In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). The objective of ASU 2016-13 is to provide financial statement users with decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit. ASU 2016-13 includes provisions that require financial assets measured at amortized cost (such as loans and held to maturity (HTM) debt securities) to be presented at the net amount expected to be collected. This will be accomplished through recognition of an estimate of all current expected credit losses. The estimate will include forecasted information for the timeframe that an entity is able to develop reasonable and supportable forecasts. This is a change from the current practice of recognizing incurred losses based on the probable initial recognition threshold under current GAAP. In addition, credit losses on available for sale (AFS) debt securities will be recorded through an allowance for credit losses rather than as a write-down. Under ASU 2016-13, an entity will be able to record reversals of credit losses in current period income when the estimate of credit losses declines, whereas current GAAP prohibits reflecting those improvements in current period earnings. ASU 2016-13 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2019, initially, and early adoption is permitted for fiscal years, including interim periods, beginning after December 15, 2018. ASU 2016-13 will be applied through a cumulative effect adjustment to retained earnings (modified-retrospective approach), except for debt securities for which an other-than-temporary impairment had been recognized before the effective date. A prospective transition approach is required for these debt securities. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures, including software solutions, data requirements and loss estimation methodologies. The company has engaged a third party advisor to develop a new expected loss model. While the effects cannot yet be quantified, the Company expects ASU 2016-13 to add complexity and costs to its current credit loss evaluation process. On July 2019, FASB proposed the effective date delay to January 2020 for SEC filers, excluding smalller reporting companies (SRCs), and January 2023 for all other entities including SRCs. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement”. ASU 2018-13 adds, modifies, and removes disclosure requirements for fair value measurements. ASU 2018-13 is effective annual periods in fiscal years beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted upon the issuance of ASU 2018-13. The Company does not expect this ASU to have a material impact on its financial statements and disclosures. In February 2016, the FASB issued its new lease accounting guidance in ASU No. 2016-02, Leases (Topic 842) Codification Improvements to Topic 842, Leases Leases (Topic 842): Targeted Improvements In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20) (ASU 2017-08). ASU 2017-08 amends the amortization period for certain purchased callable debt securities held at a premium. Prior to the issuance of this guidance, premiums were amortized as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 requires premiums on purchased callable debt securities that have explicit, noncontingent call features that are callable at fixed prices to be amortized to the earliest call date. There are no accounting changes for securities held at a discount. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018, and early adoption is permitted. ASU 2017-08 will be applied through a cumulative effect adjustment through equity (modified-retrospective approach). The Company did not have callable debt securities held at a premium at December 31, 2018 or June 30, 2019.

The amortized cost and estimated fair value of securities available for sale at June 30, 2019, by contractual maturity, are shown below. Securities without a contractual maturity are shown separately.

In analyzing an issuer’s financial condition, the Company may consider whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. The fair value is expected to recover as the securities approach maturity. Management does not intend to sell and it is likely that management will not be required to sell the securities prior to their anticipated recovery. There were no securities pledged as collateral at June 30, 2019 or December 31, 2018.

There were no new loans identified as trouble debt restructurings during the three and six months ended June 30, 2019 or during the year ended December 31, 2018. There were no payment defaults during the three and six months ended June 30, 2019 or during the year ended December 31, 2018 of loans that had been modified as troubled debt restructurings within the previous twelve months. Credit Quality Indicators 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 Company’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. Doubtful—Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass-rated loans. As of June 30, 2019 and December 31, 2018, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: Pass Special Mention Substandard Doubtful Total As of June 30, 2019: (Dollars in thousands) Commercial real estate $ 585,138 $ — $ — $ — $ 585,138 SBA loans—real estate 118,425 777 2,264 — 121,466 SBA loans—non-real estate 10,117 15 41 — 10,173 Commercial and industrial 102,653 898 1,892 — 105,443 Home mortgage 124,465 — — — 124,465 Consumer 3,341 — — — 3,341 $ 944,139 $ 1,690 $ 4,197 $ — $ 950,026 As of December 31, 2018: Commercial real estate $ 505,229 $ — $ — $ — $ 505,229 SBA loans—real estate 115,993 — 2,000 — 117,993 SBA loans—non-real estate 9,859 16 57 — 9,932 Commercial and industrial 112,781 — 1,516 — 114,297 Home mortgage 127,806 — — — 127,806 Consumer 2,586 — — — 2,586 $ 874,254 $ 16 $ 3,573 $ — $ 877,843

Leases [Abstract]
Leases	Note 5. Leases On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (Topic 842) , using the optional transition method permitted by ASU No. 2018-11, Leases (Topic 842): Targeted Improvements . The Company’s operating leases are real estate leases which are comprised of its headquarters and office facilities from nonaffiliated parties with remaining lease terms ranging from 1 to 10 years as of June 30, 2019. Certain lease arrangements contain extension option which are typically around 5 years. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term. At June 30, 2019, operating right-of-use (“ROU”) assets and related liabilities were $9.0 million and $10.7 million, respectively. Short-term operating leases, which are defined as leases with term of twelve months or less, were not recognized as ROU assets with related lease liabilities as permitted under ASU No. 2016-02. The lease payments on short-term operating leases are immaterial. The Company did not have any finance leases at June 30, 2019. Operating lease ROU assets represent the Company’s right to use the underlying asset during the lease term and operating lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and operating lease liabilities are recognized at lease commencement based on the present value of the remaining lease payments using the Company’s incremental borrowing rate at the lease commencement date. Operating lease expense, which is comprised of amortization of the ROU asset and the implicit interest accreted on the operating lease liability, is recognized on a straight-line basis over the lease term and is recorded in occupancy expense in the consolidated statements of income. The Company’s occupancy expense also includes variable lease costs which is comprised of the Company's share of actual costs for utilities, common area maintenance, property taxes, and insurance that are not included in lease liabilities and are expensed as incurred. Variable lease costs can also include rent escalations based on changes to indices, such as the Consumer Price Index, where the Company estimates future rent increases and records the actual difference to variable costs. The table below summarized the Company’s total lease cost: Three Months Ended Six Months Ended (Dollars in thousands) June 30, 2019 June 30, 2019 Operating lease cost $ 440 $ 843 Variable lease cost 176 337 Total lease cost $ 616 $ 1,180 The table below summarizes other information related to the Company’s operating leases: Three Months Ended Six Months Ended (Dollars in thousands) June 30, 2019 June 30, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 479 $ 915 Weighted average remaining lease term - operating leases 6.2 years Weighted average discount rate - operating leases 2.98 % Rent expense was $616,000 and $538,000 for the three months ended June 30, 2019 and 2018, and $1.2 million and $1.1 million for the six months ended June 30, 2019 and 2018, respectively.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	Note 14. Revenue Recognition Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers ("ASC 606"), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied. The majority of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans, letters of credit, and investment securities, as well as revenue related to mortgage servicing activities and revenue on bank owned life insurance, as these activities are subject to other GAAP discussed elsewhere within the disclosures. Descriptions of the Company’s revenue-generating activities that are within the scope of ASC 606, which are presented in the Company’s income statements as components of noninterest income are as follows: Service charges on deposits Wire transfer fee income: Other revenue streams that are recorded in other income in noninterest income include revenue generated from letters of credit and income on bank owned life insurance.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 15. Fair Value of Financial Instruments Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1—Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2—Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3—Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate fair value: Securities Available for Sale Other Investment Impaired Loans Appraisals for collateral-dependent impaired loans are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the credit department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Assets and liabilities measured at fair value on a recurring basis as of June 30, 2019 and December 31, 2018 are summarized below: Fair Value Measuring Using Quoted Significant Other Significant Prices in Observable Unobservable Total Active Markets Inputs Inputs Fair Value (Level 1) (Level 2) (Level 3) (Dollars in thousands) As of June 30, 2019 : U.S. Government sponsored agency securities $ 6,981 $ — $ 6,981 $ — Mortgage-backed securities - residential 12,730 — 12,730 — Collateralized mortgage obligations 32,118 — 32,118 — Other investments: Mutual fund - CRA qualified 2,586 2,586 — — As of December 31, 2018 : U.S. Government sponsored agency securities $ 6,906 $ — $ 6,906 $ — Mortgage-backed securities - residential 14,129 — 14,129 — Collateralized mortgage obligations 34,301 — 34,301 — Other investments: Mutual fund - CRA qualified 2,488 2,488 — — There were no transfers between Level 1 and Level 2 in the six months ended June 30, 2019 or 2018.

Regulatory Capital Requirements [Abstract]
Regulatory Capital Matters	Note 16. Regulatory Capital Matters Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Under the Basel III rules, the Bank must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer was 0.625% in 2016 and increased 0.625% annually until 2019. As of Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At June 30, 2019 and December 31, 2018, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category.

Earnings Per Share [Abstract]
Earnings Per Share	Note 17. Earnings per Share The two-class method is used in the calculation of basic and diluted earnings per share. Under the two-class method, earnings available to common shares are allocated between common shares and participating securities. The Company’s restricted stock awards are considered participating securities as the unvested awards have non-forfeitable rights to dividends, paid or unpaid, on unvested awards. The factors used in the earnings per share computation follow: Three Months Ended June 30, (Dollars in thousands, except share data) 2019 2018 Basic Net income $ 3,836 $ 3,791 Undistributed earnings allocated to participating securities (101 ) (107 ) Net income allocated to common shares 3,735 3,684 Weighted average common shares outstanding 15,685,478 15,577,772 Basic earnings per common share $ 0.24 $ 0.24 Diluted Net income allocated to common shares $ 3,735 $ 3,684 Weighted average common shares outstanding for basic earnings per common share 15,685,478 15,577,772 Add: Dilutive effects of assumed exercises of stock options 266,120 532,685 Average shares and dilutive potential common shares 15,951,598 16,110,457 Diluted earnings per common share $ 0.23 $ 0.23 Six Months Ended June 30, (Dollars in thousands, except share data) 2019 2018 Basic Net income $ 8,576 $ 7,007 Undistributed earnings allocated to participating securities (228 ) (213 ) Net income allocated to common shares 8,348 6,794 Weighted average common shares outstanding 15,750,905 14,441,241 Basic earnings per common share $ 0.53 $ 0.47 Diluted Net income allocated to common shares $ 8,348 $ 6,794 Weighted average common shares outstanding for basic earnings per common share 15,750,905 14,441,241 Add: Dilutive effects of assumed exercises of stock options 255,594 510,340 Average shares and dilutive potential common shares 16,006,499 14,951,581 Diluted earnings per common share $ 0.52 $ 0.45 No shares of common stock were antidilutive for the three and six months ended June 30, 2019.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited consolidated financial statements and notes thereto of the Company have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) for Form 10-Q and conform to practices within the banking industry and include all of the information and disclosures required by accounting principles generally accepted in the United States of America (“GAAP”) for interim financial reporting. The accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments), which are necessary for a fair presentation of financial results for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results for the full year. These interim unaudited financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto as of and for the year ended December 31, 2018, included in the Companys’ Annual Report on Form 10-K for the year ended December 31, 2018.
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 and Federal Home Loan Bank advances 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. 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. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement, and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis.
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 are recognized in other income in the Consolidated Statements of Income and Comprehensive 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	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 loan 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 Loan Losses	Allowance for Loan Losses: The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that in management’s judgment should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is 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. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings and classified as impaired. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan’s effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of reserve in accordance with the accounting policy for the allowance for loan losses. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial real estate and construction loans. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Income recognition on impaired loans materially conforms to the method the Company uses for income recognition on nonaccrual loans. Allowance for impaired loans is determined based on the present value of the estimated cash flows or on the fair value of the collateral if the loan is collateral dependent, less costs to sell. If the measured fair value is less than the recorded investment in the loan, the deficiency will be charged off against the allowance for loan losses, or alternatively, a specific allocation will be established. For consumer loans, management will generally charge off the balance if the loan is 90 days or more past due. The general component of the allowance covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced by the Company over the most recent two years. For those portfolio segments that the Company does not have sufficient historical data available to track the loss migration, the loss factors are based on the actual loss history experienced by the Company over the most recent five years. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified in the Company’s loan portfolio, and are also representative of the classes within the portfolio: commercial real estate, SBA loans—real estate, SBA loans—non-real estate, commercial and industrial, home mortgage, and consumer. The Company reviews the credit risk exposure of all its portfolio segments by internally assigned grades. The Company categorizes loans into risk grades based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. For the home mortgage and consumer portfolio segments, the Company’s primary monitoring tool is reviewing past due listings to determine if the loans are performing. The determination of the allowance for loan losses is based on estimates that are particularly susceptible to changes in the economic environment and market conditions. Management believes that as of June 30, 2019 and December 31, 2018 the allowance for loan losses is adequate based on information currently available. If a deterioration in the economy of the Company’s principal market area occurs, the Company’s loan portfolios could be adversely impacted and higher charge-offs and increases in non-performing assets could result. Such an adverse impact could also require a larger allowance for loan losses.
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.
Other Real Estate Owned, Net	Other Real Estate Owned, Net: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Physical possession of residential real estate property collateralizing a consumer mortgage loan occurs when the legal title is obtained upon completion of foreclosure or when the borrower conveys all interest in the property to satisfy the loan through the completion of a deed in lieu of foreclosure or through a similar legal agreement. These assets are subsequently accounted for at the lower of their cost or fair value less estimated costs to sell. If their fair value declines subsequent to foreclosure, a valuation allowance is recorded through expense. Operating costs after acquisition are expensed.
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.
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. The Company does not expect the total amount of unrecognized tax benefits to significantly increase or decrease in the next twelve months. The Company recognizes interest and/or penalties related to income tax matters in income tax expense. There were no interest or penalties recognized in the three and six months ended June 30, 2019 or 2018.
Comprehensive Income/(Loss)	Comprehensive Income/(Loss): Comprehensive income/(loss) consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available for sale, 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 15—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.
Reclassifications	Reclassifications: Some items in the prior period financial statements were reclassified to conform to the current presentation. Reclassification had no effect on prior year net income or shareholders’ equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). The objective of ASU 2016-13 is to provide financial statement users with decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit. ASU 2016-13 includes provisions that require financial assets measured at amortized cost (such as loans and held to maturity (HTM) debt securities) to be presented at the net amount expected to be collected. This will be accomplished through recognition of an estimate of all current expected credit losses. The estimate will include forecasted information for the timeframe that an entity is able to develop reasonable and supportable forecasts. This is a change from the current practice of recognizing incurred losses based on the probable initial recognition threshold under current GAAP. In addition, credit losses on available for sale (AFS) debt securities will be recorded through an allowance for credit losses rather than as a write-down. Under ASU 2016-13, an entity will be able to record reversals of credit losses in current period income when the estimate of credit losses declines, whereas current GAAP prohibits reflecting those improvements in current period earnings. ASU 2016-13 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2019, initially, and early adoption is permitted for fiscal years, including interim periods, beginning after December 15, 2018. ASU 2016-13 will be applied through a cumulative effect adjustment to retained earnings (modified-retrospective approach), except for debt securities for which an other-than-temporary impairment had been recognized before the effective date. A prospective transition approach is required for these debt securities. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures, including software solutions, data requirements and loss estimation methodologies. The company has engaged a third party advisor to develop a new expected loss model. While the effects cannot yet be quantified, the Company expects ASU 2016-13 to add complexity and costs to its current credit loss evaluation process. On July 2019, FASB proposed the effective date delay to January 2020 for SEC filers, excluding smalller reporting companies (SRCs), and January 2023 for all other entities including SRCs. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement”. ASU 2018-13 adds, modifies, and removes disclosure requirements for fair value measurements. ASU 2018-13 is effective annual periods in fiscal years beginning after December 15, 2019, including interim periods within those annual periods. Early adoption is permitted upon the issuance of ASU 2018-13. The Company does not expect this ASU to have a material impact on its financial statements and disclosures. In February 2016, the FASB issued its new lease accounting guidance in ASU No. 2016-02, Leases (Topic 842) Codification Improvements to Topic 842, Leases Leases (Topic 842): Targeted Improvements In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20) (ASU 2017-08). ASU 2017-08 amends the amortization period for certain purchased callable debt securities held at a premium. Prior to the issuance of this guidance, premiums were amortized as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 requires premiums on purchased callable debt securities that have explicit, noncontingent call features that are callable at fixed prices to be amortized to the earliest call date. There are no accounting changes for securities held at a discount. This ASU is effective for annual periods and interim periods within those annual periods beginning after December 15, 2018, and early adoption is permitted. ASU 2017-08 will be applied through a cumulative effect adjustment through equity (modified-retrospective approach). The Company did not have callable debt securities held at a premium at December 31, 2018 or June 30, 2019.
