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.

Summary of Significant Accounti

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, including eliminating intercompany transactions and balances. 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. 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. There has been no significant or material changes to the Company’s accounting policies during the three months ended September 30, 2019, as compared to the Summary of Significant Accounting Policies as described in “Note 2 of the Notes to Consolidated Financial Statements” in the Company’s unaudited consolidated financial statements included in its Quarterly Report on Form 10-Q for the period ended June 30, 2019. 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, and on October 2019, FASB voted to approve the proposed delay. The Board will draft a final ASU for vote by written ballot. The Compnay expects the adoption date would be January 2023. 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 September 30, 2019.

The amortized cost and estimated fair value of securities available for sale at September 30, 2019, by contractual maturity, are shown below. Securities without a contractual maturity are shown separately. Amortized Cost Fair Value As of September 30, 2019: (Dollars in thousands) Available for sale: Within one year $ 3,998 $ 3,995 One to five years 2,000 1,997 Mortgage-backed securities: residential 12,160 12,197 Collateralized mortgage obligations 33,757 34,106 Total available for sale $ 51,915 $ 52,295 Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. At September 30, 2019 and December 31, 2018, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of shareholders’ equity. The following table summarizes securities with unrealized losses as of September 30, 2019 and December 31, 2018, aggregated by length of time in a continuous unrealized loss position: Less Than 12 Months 12 Months or Longer Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses As of September 30, 2019: (Dollars in thousands) Available for sale: U.S. Government sponsored agency securities $ 1,000 $ — $ 3,992 $ (6 ) $ 4,992 $ (6 ) Mortgage-backed securities: residential 1,176 — 3,442 (24 ) 4,618 (24 ) Collateralized mortgage obligations 2,140 (14 ) 4,014 (32 ) 6,154 (46 ) Total available for sale $ 4,316 $ (14 ) $ 11,448 $ (62 ) $ 15,764 $ (76 ) Less Than 12 Months 12 Months or Longer Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses As of December 31, 2018: (Dollars in thousands) Available for sale: U.S. Government sponsored agency securities $ — $ — $ 6,906 $ (88 ) $ 6,906 $ (88 ) Mortgage-backed securities: residential 3,209 (23 ) 10,920 (313 ) 14,129 (336 ) Collateralized mortgage obligations 3,348 (26 ) 14,544 (484 ) 17,892 (510 ) Total available for sale $ 6,557 $ (49 ) $ 32,370 $ (885 ) $ 38,927 $ (934 ) The Company believes that the unrealized losses are temporary, arising mainly from fluctuations in interest rates and do not reflect a deterioration of credit quality of the issuers. 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. 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. As of September 30, 2019, management believes no securities with unrealized losses were OTTI. There were no securities pledged as collateral as of September 30, 2019 or December 31, 2018. Other investments as of September 30, 2019 and December 31, 2018, consisted of the following: September 30, 2019 December 31, 2018 (Dollars in thousands) FHLB stock $ 5,358 $ 4,582 PCBB stock 190 190 Mutual fund - CRA qualified 3,625 2,488 Total other investments $ 9,173 $ 7,260

There were no new loans identified as trouble debt restructurings during the three and nine months ended September 30, 2019 or 2018. There were no payment defaults during the three and nine months ended September 30, 2019 or 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 September 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 September 30, 2019: (Dollars in thousands) Commercial real estate $ 595,903 $ — $ — $ — $ 595,903 SBA loans—real estate 122,553 773 2,247 — 125,573 SBA loans—non-real estate 11,281 14 36 — 11,331 Commercial and industrial 106,379 893 710 — 107,982 Home mortgage 123,325 — 256 — 123,581 Consumer 2,875 — — — 2,875 $ 962,316 $ 1,680 $ 3,249 $ — $ 967,245 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 September 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 September 30, 2019, operating right-of-use (“ROU”) assets and related liabilities were $8.6 million and $10.3 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 September 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 the 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 Nine Months Ended (Dollars in thousands) September 30, 2019 September 30, 2019 Operating lease cost $ 444 $ 1,287 Variable lease cost 211 548 Total lease cost $ 655 $ 1,835 The table below summarizes other information related to the Company’s operating leases: Three Months Ended Nine Months Ended (Dollars in thousands) September 30, 2019 September 30, 2019 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 493 $ 1,408 Weighted average remaining lease term - operating leases 6.0 years Weighted average discount rate - operating leases 2.98 % Rent expense was $655,000 and $545,000 for the three months ended September 30, 2019 and 2018, respectively, and $1.8 million and $1.6 million for the nine months ended September 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. These revenue streams are either not material or out of scope of ASC 606.

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 September 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 September 30, 2019 : U.S. Government sponsored agency securities $ 5,992 $ — $ 5,992 $ — Mortgage-backed securities - residential 12,197 — 12,197 — Collateralized mortgage obligations 34,106 — 34,106 — Other investments: Mutual fund - CRA qualified 3,625 3,625 — — 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 nine months ended September 30, 2019 or 2018. There were no other assets or liabilities, except OREO measured at fair value on a non-recurring basis as of September 30, 2019 or December 31, 2018. OREO is reported at fair value.

Regulatory Capital Matters

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 September 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. Actual and required capital amounts (in thousands) and ratios, exclusive of the capital conservation buffer, are presented below as of September 30, 2019 and December 31, 2018: Required for Minimum Capital Adequacy To be Considered Actual Purposes "Well Capitalized" (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio As of September 30, 2019: Total capital (to risk-weighted assets) Consolidated $ 146,641 15.36 % N/A N/A N/A N/A Bank 143,407 15.03 % 76,332 8.00 % 95,415 10.00 % Tier 1 capital (to risk-weighted assets) Consolidated 136,922 14.35 % N/A N/A N/A N/A Bank 133,688 14.01 % 57,249 6.00 % 76,332 8.00 % Common equity Tier 1 capital (to risk-weighted assets) Consolidated 136,922 14.35 % N/A N/A N/A N/A Bank 133,688 14.01 % 42,937 4.50 % 62,020 6.50 % Tier 1 capital (to average assets) Consolidated 136,922 12.11 % N/A N/A N/A N/A Bank 133,688 11.83 % 45,212 4.00 % 56,515 5.00 % Required for Minimum Capital Adequacy To be Considered Actual Purposes "Well Capitalized" (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio As of December 31, 2018: Total capital (to risk-weighted assets) Consolidated $ 139,593 16.26 % N/A N/A N/A N/A Bank 139,538 16.25 % 68,686 8.00 % 85,857 10.00 % Tier 1 capital (to risk-weighted assets) Consolidated 129,893 15.13 % N/A N/A N/A N/A Bank 129,838 15.12 % 51,514 6.00 % 68,686 8.00 % Common equity Tier 1 capital (to risk-weighted assets) Consolidated 129,893 15.13 % N/A N/A N/A N/A Bank 129,838 15.12 % 38,636 4.50 % 55,807 6.50 % Tier 1 capital (to average assets) Consolidated 129,893 12.88 % N/A N/A N/A N/A Bank 129,838 12.87 % 40,346 4.00 % 50,432 5.00 %

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.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 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, including eliminating intercompany transactions and balances. 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.
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. There has been no significant or material changes to the Company’s accounting policies during the three months ended September 30, 2019, as compared to the Summary of Significant Accounting Policies as described in “Note 2 of the Notes to Consolidated Financial Statements” in the Company’s unaudited consolidated financial statements included in its Quarterly Report on Form 10-Q for the period ended June 30, 2019.
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, and on October 2019, FASB voted to approve the proposed delay. The Board will draft a final ASU for vote by written ballot. The Compnay expects the adoption date would be January 2023. 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 September 30, 2019.
