Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	ORGANIZATION PacWest Bancorp, a Delaware corporation, is a bank holding company registered under the BHCA, with our corporate headquarters located in Beverly Hills, California. Our principal business is to serve as the holding company for our wholly-owned subsidiary, Pacific Western Bank. References to "Pacific Western" or the "Bank" refer to Pacific Western Bank together with its wholly-owned subsidiaries. References to "we," "us," or the "Company" refer to PacWest Bancorp together with its subsidiaries on a consolidated basis. When we refer to "PacWest" or to the "holding company," we are referring to PacWest Bancorp, the parent company, on a stand-alone basis. We are focused on relationship-based business banking to small, middle-market and venture-backed businesses nationwide. The Bank offers a broad range of loan and lease and deposit products and services through 70 full-service branches located in California, one branch located in Durham, North Carolina, one branch located in Denver, Colorado, and numerous loan production offices across the country. The Bank provides community banking products including lending and comprehensive deposit and treasury management services to small and medium-sized businesses conducted primarily through our California-based branch offices and Denver, Colorado branch office. The Bank offers national lending products including asset-based, equipment, and real estate loans and treasury management services to established middle-market businesses on a national basis. The Bank also offers venture banking products including a comprehensive suite of financial services focused on entrepreneurial and venture-backed businesses and their venture capital and private equity investors, with offices located in key innovation hubs across the United States. In addition, we provide investment advisory and asset management services to select clients through Pacific Western Asset Management Inc., a wholly-owned subsidiary of the Bank and an SEC-registered investment adviser. We generate our revenue primarily from interest received on loans and leases and, to a lesser extent, from interest received on investment securities, and fees received in connection with deposit services, extending credit and other services offered, including foreign exchange services. Our major operating expenses are interest paid by the Bank on deposits and borrowings, compensation, occupancy, and general operating expenses. Significant Accounting Policies Our accounting policies are described in Note 1. Nature of Operations and Summary of Significant Accounting Policies , of our audited consolidated financial statements included in our Annual R eport on Form 10-K for the year ended December 31, 2020 as filed with the Securities and Exchange Commission ("Form 10-K"). Accounting Standards Adopted in 2021 Effective January 1, 2021, the Company adopted ASU 2019-12, “ Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ” which simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The amendment also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. Effective January 1, 2021, the Company adopted ASU 2020-01, “ Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) ” which clarifies that entities that apply the measurement alternative in ASC 321 should consider observable transactions that result in entities initially applying or discontinuing the use of the equity method of accounting under ASC 323. The guidance also clarifies that certain forward contracts and purchased options on equity securities that are not deemed to be in-substance common stock under ASC 323 or accounted for as derivatives under ASC 815 are in the scope of ASC 321. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. Effective January 1, 2021, the Company adopted ASU 2020-08, “ Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs ” which clarifies the Company should reevaluate whether a callable debt security that has multiple call dates is within the scope of ASC 310-20-35-33 at each reporting period. ASC 310-20-35-33 requires that, to the extent the amortized cost basis of an individual callable debt security exceeds the amount repayable by the issuer at the next call date, the excess should be amortized to the earliest call date. As the Company’s accounting policy to amortize premiums on investments in callable debt securities to the earliest call date is consistent with the manner required by ASU 2020-08, the adoption of this standard had no impact on the Company’s condensed consolidated financial statements. Basis of Presentation Our interim condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K. Use of Estimates We have made a number of estimates and assumptions related to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of goodwill and other intangible assets, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

We concluded the unrealized losses were a result of the level of market interest rates relative to the types of securities and pricing changes caused by shifting supply and demand dynamics and not a result of downgraded credit ratings or other indicators of deterioration of the underlying issuers' ability to repay. We also considered the seniority of the tranches and U.S. government agency guarantees, if any, to assess whether an unrealized loss was credit-related. Accordingly, we determined the unrealized losses were not credit-related and recognized the unrealized losses in "other comprehensive income" in stockholders' equity. Although we periodically sell securities for portfolio management purposes, we do not foresee having to sell any impaired securities strictly for liquidity needs and believe that it is more likely than not we would not be required to sell any impaired securities before recovery of their amortized cost. Contractual Maturities of Securities Available-for-Sale The following table presents the contractual maturities of our securities available-for-sale portfolio based on amortized cost and carrying value as of the date indicated: March 31, 2021 Amortized Fair Maturities Cost Value (In thousands) Due in one year or less $ 16,309 $ 16,075 Due after one year through five years 571,182 598,902 Due after five years through ten years 1,963,578 1,989,510 Due after ten years 3,243,624 3,337,203 Total securities available-for-sale $ 5,794,693 $ 5,941,690 CMBS, CMOs, and MBS have contractual maturity dates, but require periodic payments based upon scheduled amortization terms. Actual principal collections on these securities usually occur more rapidly than the scheduled amortization terms because of prepayments made by obligors of the underlying loan collateral.

Loans and Leases	LOANS AND LEASES Our loans are carried at the principal amount outstanding, net of deferred fees and costs, and in the case of acquired and purchased loans, net of purchase discounts and premiums. Deferred fees and costs and purchase discounts and premiums on acquired loans are recognized as an adjustment to interest income over the contractual life of the loans primarily using the effective interest method or taken into income when the related loans are paid off or included in the carrying amount of loans that are sold.

Leases Receivable We provide equipment financing to our customers primarily with operating and direct financing leases. For direct financing leases, lease receivables are recorded on the balance sheet but the leased equipment is not, although we generally retain legal title to the leased equipment until the end of each lease. Direct financing leases are stated at the net amount of minimum lease payments receivable, plus any unguaranteed residual value, less the amount of unearned income and net acquisition discount at the reporting date.

We actively participated in both rounds of the Paycheck Protection Program ("PPP"), under the provisions of the CARES Act during 2020 and 2021. As of March 31, 2021, PPP loans had an outstanding balance of approximately $1.1 billion. The loans are fully guaranteed by the SBA, and do not carry an allowance. A loan is considered collateral-dependent, and is individually evaluated for reserve purposes, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS, NET Goodwill and other intangible assets arise from the acquisition method of accounting for business combinations. Goodwill and other intangible assets generated from business combinations and deemed to have indefinite lives are not subject to amortization and instead are tested for impairment annually unless a triggering event occurs thereby requiring an updated assessment. Our regular annual impairment assessment occurs in the fourth quarter. Goodwill represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Impairment exists when the carrying value of the goodwill exceeds its fair value. An impairment loss would be recognized in an amount equal to that excess as a charge to "Noninterest expense" in the condensed consolidated statements of earnings (loss). The following table presents the changes in the carrying amount of goodwill for the period indicated: Goodwill (In thousands) Balance, December 31, 2020 $ 1,078,670 Addition from the Civic acquisition 125,422 Balance, March 31, 2021 $ 1,204,092 Our other intangible assets with definite lives are CDI and CRI. CDI and CRI are amortized over their respective estimated useful lives and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or customer relationships acquired. The following table presents the estimated aggregate future amortization expense for our current intangible assets as of the date indicated: March 31, 2021 (In thousands) Period ending December 31, 2021 $ 8,142 2022 7,672 2023 3,787 2024 1,711 Net CDI and CRI $ 21,312 The following table presents the changes in CDI and CRI and the related accumulated amortization for the periods indicated: Three Months Ended March 31, 2021 2020 (In thousands) Gross Amount of CDI and CRI: Balance, beginning of period $ 109,646 $ 117,573 Addition from Civic acquisition 750 — Fully amortized portion (9,846) — Balance, end of period 100,550 117,573 Accumulated Amortization: Balance, beginning of period (86,005) (79,179) Amortization expense (3,079) (3,948) Fully amortized portion 9,846 — Balance, end of period (79,238) (83,127) Net CDI and CRI, end of period $ 21,312 $ 34,446

These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the condensed consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement that the Company has in particular classes of financial instruments. Commitments to extend credit are contractual agreements to lend to our customers when customers are in compliance with their contractual credit agreements and when customers have contractual availability to borrow under such agreements. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. We provide standby letters of credit in conjunction with several of our lending arrangements and property lease obligations. Most guarantees expire within one year from the date of issuance. If a borrower defaults on its commitments subject to any letter of credit issued under these arrangements, we would be required to meet the borrower's financial obligation but would seek repayment of that financial obligation from the borrower. In some cases, borrowers have pledged cash and investment securities as collateral under these arrangements. In addition, we invest in SBICs that call for capital contributions up to an amount specified in the partnership agreements, and in CRA-related loan pools. As of March 31, 2021 and December 31, 2020, we had commitments to contribute capital to these entities totaling $54.8 million and $55.5 million. The following table presents the years in which commitments are expected to be paid for our commitments to contribute capital to small business investment companies and CRA-related loan pools as of the date indicated: March 31, 2021 (In thousands) Period ending December 31, 2021 $ 27,393 2022 27,392 Total $ 54,785 Legal Matters In the ordinary course of our business, the Company is party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon currently available information, any resulting liability, in addition to amounts already accrued, and taking into consideration insurance which may be applicable, would not have a material adverse effect on the Company’s financial statements or operations. The range of any reasonably possible liabilities is also not significant.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily securities available-for-sale and derivatives. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period and such measurements are therefore considered “nonrecurring” for purposes of disclosing our fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for individually evaluated loans and leases and other real estate owned and also to record impairment on certain assets, such as goodwill, CDI, and other long-lived assets. For information regarding the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820), and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825, as amended by ASU 2016-01 and ASU 2018-03), see Note 1. Nature of Operations and Summary of Significant Accounting Policies, and Note 13. Fair Value Measurements, to the Consolidated Financial Statements of the Company's Form 10-K. The Company also holds SBIC investments measured at fair value using the NAV per share practical expedient that are not required to be classified in the fair value hierarchy. At March 31, 2021, the fair value of these investments was $33.4 million. The following tables present information on the assets and liabilities measured and recorded at fair value on a recurring basis as of the dates indicated: Fair Value Measurements as of March 31, 2021 Measured on a Recurring Basis Total Level 1 Level 2 Level 3 (In thousands) Securities available-for-sale: Municipal securities $ 1,646,054 $ — $ 1,646,054 $ — Agency commercial MBS 1,273,402 — 1,273,402 — Agency residential CMOs 1,108,828 — 1,108,828 — U.S. Treasury securities 491,358 491,358 — — Agency residential MBS 433,100 — 433,100 — Corporate debt securities 380,407 — 380,407 — Collateralized loan obligations 244,240 — 244,240 — Asset-backed securities 224,015 — 200,133 23,882 Private label residential CMOs 103,376 — 98,962 4,414 SBA securities 36,910 — 36,910 — Total securities available-for-sale $ 5,941,690 $ 491,358 $ 5,422,036 $ 28,296 Equity investments with readily determinable fair values $ 10,266 $ 10,266 $ — $ — Derivatives (1) : Equity warrants 4,589 — — 4,589 Interest rate and economic contracts 3,168 — 3,168 — Derivative liabilities 1,421 — 1,421 — Fair Value Measurements as of December 31, 2020 Measured on a Recurring Basis Total Level 1 Level 2 Level 3 (In thousands) Securities available-for-sale: Agency commercial MBS $ 1,281,877 $ — $ 1,281,877 $ — Agency residential CMOs 1,219,880 — 1,219,880 — Municipal securities 1,531,617 — 1,531,617 — Agency residential MBS 341,074 — 341,074 — Asset-backed securities 249,503 — 223,778 25,725 Collateralized loan obligations 135,876 — 135,876 — Private label residential CMOs 116,946 — 112,299 4,647 SBA securities 41,627 — 41,627 — Corporate debt securities 311,889 — 311,889 — U.S. Treasury securities 5,302 5,302 — — Total securities available-for-sale $ 5,235,591 $ 5,302 $ 5,199,917 $ 30,372 Equity investments with readily determinable fair values $ 6,147 $ 6,147 $ — $ — Derivatives (1) : Equity warrants 4,520 — — 4,520 Interest rate and economic contracts 4,230 — 4,230 — Derivative liabilities 1,150 — 1,150 — ____________________ (1) For information regarding derivative instruments, see Note 11.

These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a portion of the Company’s financial instruments, fair value estimates are based on what management believes to be reasonable judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of March 31, 2021, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION The Company’s 2017 Stock Incentive Plan, or the 2017 Plan, permits stock-based compensation awards to officers, directors, employees, and consultants. The 2017 Plan authorized grants of stock-based compensation instruments to purchase or issue up to 4,000,000 shares of Company common stock. As of March 31, 2021, there were 990,570 sh ares available for grant under the 2017 Plan. Restricted Stock Restricted stock amortization totaled $6.4 million and $6.5 million for the three months ended March 31, 2021 and 2020. Such amounts are included in "Compensation expense" on the condensed consolidated statements of earnings (loss). The amount of unrecognized compensation expense related to unvested TRSAs and PRSUs as of March 31, 2021 totaled $67.2 million . Time-Based Restricted Stock Awards At March 31, 2021, there wer e 2,189,181 shar es of unvested TRSAs outstanding pursuant to the Company's 2017 Plan. The TRSAs generally vest ratably over a service period of three or four years from the date of the grant or immediately upon death of an employee. Compensation expense related to TRSAs is based on the fair value of the underlying award on the grant date and is recognized over the vesting period using the straight-line method. Performance-Based Restricted Stock Units At March 31, 2021, there were 531,333 units of unvested PRSUs that have been granted. The PRSUs will vest only if performance goals with respect to certain financial metrics are met over a three-year performance period. The shares underlying the PRSUs are not considered issued and outstanding until they vest. PRSUs are granted and initially expensed based on a target number. The number of shares that will ultimately vest based on actual performance will range from zero to a maximum of either 150% or 200% of target.

Recently Issued Accounting Standards	RECENTLY ISSUED ACCOUNTING STANDARDS Effective Effect on the Financial Statements Standard Description Date or Other Significant Matters ASU 2020-04, " Reference Rate Reform (Topic 848) " and ASU 2021-01, “ Reference Rate Reform (Topic 848): Scope) " This Update provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other agreements affected by the anticipated transition away from LIBOR toward new interest reference rates. For agreements that are modified because of reference rate reform and that meet certain scope guidance: (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered “minor” so that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. Additionally, the amendments in ASU 2021-01 clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. ASU 2020-04 is effective immediately, as of March 12, 2020, and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2022. ASU 2021-01 is also effective immediately. Entities may elect to apply the amendments on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to January 7, 2021 and up to December 31, 2022. Effective upon the issuance date of March 12, 2020, and once adopted, will apply to contract modifications made and hedging relationships entered into on or before December 31, 2022. The Company is in the process of identifying and reviewing loans and other financial instruments that are impacted by the discontinuance of LIBOR and is planning to adopt this ASU in 2021. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS Homeowners Association Services Division Acquisition Announcement On April 1, 2021, PacWest announced that the Bank entered into a definitive agreement to acquire MUFG Union Bank, N.A.’s (“Union Bank”) Homeowners Association (“HOA”) Services Division. The Bank will acquire certain assets and assume certain liabilities related to the HOA Services Division for a premium of 5.9% on deposits plus the net book values of certain assumed assets and liabilities for aggregate cash consideration of approximately $250 million. The final amount of consideration to be paid will be based on balances at closing, which is expected to occur in the fourth quarter of 2021 subject to regulatory approvals and customary closing conditions. The HOA Services Division provides a full range of banking services to community management companies and their homeowners associations. This acquisition will significantly expand the Bank’s existing HOA banking practice, which provides lockbox, electronic receivables processing and other financial services to HOA management companies. This acquisition advances the Bank’s strategy to expand its product offerings to its customers and to diversify its revenue and funding sources. Management believes that the HOA business unit’s high quality, low-cost deposits will diversify the Bank’s existing core deposits and provide an attractive funding source in a rising interest rate environment. Union Bank’s HOA Services Division is a long-time provider of specialized HOA banking services to a national base of clients with approximately $4 billion in deposits. The existing management team and employees will transition with the HOA Services Division to the Bank in connection with the close of the acquisition. Subordinated Notes Offering On April 30, 2021, the Bank completed the sale of $400 million aggregate principal amount of 3.25% Fixed-to-Floating Rate Subordinated Notes (the "Notes") due May 1, 2031 (the “Maturity Date”). Subject to any redemption prior to the Maturity Date, the Notes will bear interest from and including the original issue date to, but excluding, May 1, 2026 (the “Reset Date”), at a fixed rate of 3.25% per annum and from and including the Reset Date, but excluding the Maturity Date, the Notes will bear interest at a floating per annum rate equal to a benchmark rate (which is expected to be the Three-Month Term SOFR) plus 252 basis points. Interest on the Notes will be payable on May 1 and November 1 of each year through, but not including, the Reset Date, and quarterly thereafter on February 1, May 1, August 1, and November 1 of each year to, but not including, the Maturity Date or earlier redemption date. The first interest payment will be made on November 1, 2021. The Bank may, at its option, beginning with the interest payment date of May 1, 2026, and on any scheduled interest payment date thereafter, redeem the Notes, in whole or in part, from time to time, subject to any required regulatory approval to the extent such approval is then required, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but excluding, the date of redemption, subject to certain conditions. The discount and costs incurred in connection with the Notes offering amortize to interest expense over the term of the Notes. The Notes will qualify as Tier 2 capital for regulatory capital purposes. Common Stock Dividends On May 3, 2021, the Company announced that the Board of Directors had declared a quarterly cash dividend of $0.25 per common share. The cash dividend is payable on May 28, 2021 to stockholders of record at the close of business on May 17, 2021. The Company has evaluated events that have occurred subsequent to March 31, 2021 and have concluded there are no other subsequent events that would require recognition in the accompanying condensed consolidated financial statements.

Recently Issued Accounting Standards	Accounting Standards Adopted in 2021 Effective January 1, 2021, the Company adopted ASU 2019-12, “ Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ” which simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The amendment also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. Effective January 1, 2021, the Company adopted ASU 2020-01, “ Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) ” which clarifies that entities that apply the measurement alternative in ASC 321 should consider observable transactions that result in entities initially applying or discontinuing the use of the equity method of accounting under ASC 323. The guidance also clarifies that certain forward contracts and purchased options on equity securities that are not deemed to be in-substance common stock under ASC 323 or accounted for as derivatives under ASC 815 are in the scope of ASC 321. The adoption of this standard did not have a material impact on the Company’s condensed consolidated financial statements. Effective January 1, 2021, the Company adopted ASU 2020-08, “ Codification Improvements to Subtopic 310-20, Receivables – Nonrefundable Fees and Other Costs ” which clarifies the Company should reevaluate whether a callable debt security that has multiple call dates is within the scope of ASC 310-20-35-33 at each reporting period. ASC 310-20-35-33 requires that, to the extent the amortized cost basis of an individual callable debt security exceeds the amount repayable by the issuer at the next call date, the excess should be amortized to the earliest call date. As the Company’s accounting policy to amortize premiums on investments in callable debt securities to the earliest call date is consistent with the manner required by ASU 2020-08, the adoption of this standard had no impact on the Company’s condensed consolidated financial statements. Effective Effect on the Financial Statements Standard Description Date or Other Significant Matters ASU 2020-04, " Reference Rate Reform (Topic 848) " and ASU 2021-01, “ Reference Rate Reform (Topic 848): Scope) " This Update provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other agreements affected by the anticipated transition away from LIBOR toward new interest reference rates. For agreements that are modified because of reference rate reform and that meet certain scope guidance: (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered “minor” so that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. Additionally, the amendments in ASU 2021-01 clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. ASU 2020-04 is effective immediately, as of March 12, 2020, and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2022. ASU 2021-01 is also effective immediately. Entities may elect to apply the amendments on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to January 7, 2021 and up to December 31, 2022. Effective upon the issuance date of March 12, 2020, and once adopted, will apply to contract modifications made and hedging relationships entered into on or before December 31, 2022. The Company is in the process of identifying and reviewing loans and other financial instruments that are impacted by the discontinuance of LIBOR and is planning to adopt this ASU in 2021. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
Basis of Presentation	Basis of Presentation
Use of Estimates	Use of EstimatesWe have made a number of estimates and assumptions related to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of goodwill and other intangible assets, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.

Fair Value Disclosures [Abstract]
Fair Value Measurement, Policy	FAIR VALUE MEASUREMENTS The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily securities available-for-sale and derivatives. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period and such measurements are therefore considered “nonrecurring” for purposes of disclosing our fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for individually evaluated loans and leases and other real estate owned and also to record impairment on certain assets, such as goodwill, CDI, and other long-lived assets. For information regarding the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820), and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825, as amended by ASU 2016-01 and ASU 2018-03), see Note 1. Nature of Operations and Summary of Significant Accounting Policies, and Note 13. Fair Value Measurements, to the Consolidated Financial Statements of the Company's Form 10-K. The Company also holds SBIC investments measured at fair value using the NAV per share practical expedient that are not required to be classified in the fair value hierarchy. At March 31, 2021, the fair value of these investments was $33.4 million.

Civic, located in Redondo Beach, California, is one of the leading lenders in the United States specializing in residential non-owner-occupied investment properties. The acquisition of Civic advances the Bank’s strategy to diversify and expand its lending portfolio, diversify its revenue streams, and deploy excess liquidity into higher-yielding assets. Civic operates as a subsidiary of the Bank and at March 31, 2021 had $289.5 million of loans outstanding. The Civic acquisition has been accounted for under the acquisition method of accounting. We acquired $308.0 million of assets and assumed $148.8 million of liabilities upon closing of the acquisition. We made significant estimates and exercised significant judgment in estimating fair values and accounting for such acquired assets and assumed liabilities. Such fair values are preliminary estimates and are subject to adjustment for up to one year after the acquisition date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. The application of the acquisition method of accounting resulted in the recognition of goodwill of $125.4 million. All of the recognized goodwill is expected to be deductible for tax purposes.

Recently Issued Accounting Standards [Abstract]
Schedule of New Accounting Pronouncements and Changes in Accounting Principles	Effective Effect on the Financial Statements Standard Description Date or Other Significant Matters ASU 2020-04, " Reference Rate Reform (Topic 848) " and ASU 2021-01, “ Reference Rate Reform (Topic 848): Scope) " This Update provides optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other agreements affected by the anticipated transition away from LIBOR toward new interest reference rates. For agreements that are modified because of reference rate reform and that meet certain scope guidance: (i) modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification will be considered “minor” so that any existing unamortized origination fees/costs would carry forward and continue to be amortized and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required for modifications not accounted for as separate contracts. Additionally, the amendments in ASU 2021-01 clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. ASU 2020-04 is effective immediately, as of March 12, 2020, and may be applied prospectively to contract modifications made and hedging relationships entered into on or before December 31, 2022. ASU 2021-01 is also effective immediately. Entities may elect to apply the amendments on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to January 7, 2021 and up to December 31, 2022. Effective upon the issuance date of March 12, 2020, and once adopted, will apply to contract modifications made and hedging relationships entered into on or before December 31, 2022. The Company is in the process of identifying and reviewing loans and other financial instruments that are impacted by the discontinuance of LIBOR and is planning to adopt this ASU in 2021. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
