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 69 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 provides 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. The Bank also offers financing of business-purpose, non-owner-occupied investor properties through Civic, a wholly-owned subsidiary. The Bank also provides a specialized suite of services for the HOA industry. 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 treasury management and investment management 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, 2021 as filed with the Securities and Exchange Commission ("Form 10-K"). Accounting Standards Adopted in 2022 Effective January 1, 2022, the Company partially adopted ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326) ,” specifically the amendment related to the vintage disclosures, which requires creditors that are public entities to disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20, “Financial Instruments – Credit Losses – Measured at Amortized Cost.” The amendment also eliminates the disclosure of gross recoveries by year of origination previously presented in Example 15 in ASC 326-20-50-79, since it is not required under the guidance in ASC 326-20-50-6. The Company updated the vintage table disclosure in Note 4. Loans and Leases to present only current-period gross charge-offs by year of origination. The adoption of this amendment did not have a material 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 combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments), 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. Reclassifications Certain prior period amounts have been reclassified to conform to the current period’s presentation format. On the consolidated statements of earnings, new lines are presented for "Dividends and gains (losses) on equity investments" and "Warrant income," as those categories exceeded the disclosure materiality threshold in the fourth quarter of 2021, which previously had been included as part of "Other income. "

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 (loss)" 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, 2022 Amortized Fair Maturities Cost Value (In thousands) Due in one year or less $ 43,600 $ 43,705 Due after one year through five years 667,668 670,477 Due after five years through ten years 3,547,627 3,354,275 Due after ten years 6,235,204 5,906,652 Total securities available-for-sale $ 10,494,099 $ 9,975,109 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.

Interest income on nonaccrual loans is recognized only to the extent cash is received and the principal balance of the loan is deemed collectable.

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. Direct lease origination costs are amortized using the effective interest method over the life of the leases. Direct financing leases are subject to our accounting for allowance for loan and lease losses. See Note 8. Leases for information regarding operating leases where we are the lessor.

We actively participated in both rounds of the Paycheck Protection Program ("PPP"), under the provisions of the CARES Act during 2020 and 2021, originating $1.65 billion of such loans. As of March 31, 2022, PPP loans totaled $70.4 million, net of deferred fees. The loans have two or five year terms, ar e 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. 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 changes in CDI and CRI and the related accumulated amortization for the periods indicated: Three Months Ended March 31, 2022 2021 (In thousands) Gross Amount of CDI and CRI: Balance, beginning of period $ 133,850 $ 109,646 Addition from Civic acquisition — 750 Fully amortized portion — (9,846) Balance, end of period 133,850 100,550 Accumulated Amortization: Balance, beginning of period (88,893) (86,005) Amortization expense (3,649) (3,079) Fully amortized portion — 9,846 Balance, end of period (92,542) (79,238) Net CDI and CRI, end of period $ 41,308 $ 21,312

Restricted Stock Restricted stock amortization totaled $7.6 million and $6.4 million for the three months ended March 31, 2022 and 2021. Such amounts are included in "Compensation expense" on the condensed consolidated statements of earnings. The amount of unrecognized compensation expense related to unvested TRSAs and PRSUs as of March 31, 2022 totaled $67.3 million . Time-Based Restricted Stock Awards At March 31, 2022, there wer e 2,154,646 shar es of unvested TRSAs outstanding. TRSAs generally vest ratably over a service period of three Performance-Based Restricted Stock Units At March 31, 2022, there were 505,647 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.

Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES The following table presents a summary of commitments described below as of the dates indicated: March 31, December 31, 2022 2021 (In thousands) Loan commitments to extend credit $ 9,899,345 $ 9,006,350 Standby letters of credit 321,742 345,769 Total $ 10,221,087 $ 9,352,119 The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. 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. The estimated exposure to loss from these commitments is included in the reserve for unfunded loan commitments, which amounted to $75.1 million at March 31, 2022 and $73.1 million at December 31, 2021. 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, 2022 and December 31, 2021, we had commitments to contribute capital to these entities totaling $84.8 million and $85.9 million. The following table presents the years in which commitments are expected to be paid for our commitments to contribute capital to SBICs and CRA-related loan pools as of the date indicated: March 31, 2022 (In thousands) Period ending December 31, 2022 $ 38,496 2023 46,276 Total $ 84,772 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 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 15. 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, 2022, the fair value of these investments was $50.6 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, 2022 Measured on a Recurring Basis Total Level 1 Level 2 Level 3 (In thousands) Securities available-for-sale: Agency residential MBS $ 2,788,814 $ — $ 2,788,814 $ — Municipal securities 2,125,161 — 2,125,161 — Agency commercial MBS 1,562,337 — 1,562,337 — Agency residential CMOs 940,714 — 940,714 — U.S. Treasury securities 907,743 907,743 — — Corporate debt securities 509,156 — 509,156 — Private label commercial MBS 401,292 — 395,716 5,576 Collateralized loan obligations 363,806 — 363,806 — Private label residential CMOs 238,160 — 238,160 — Asset-backed securities 112,877 — 112,877 — SBA securities 25,049 — 25,049 — Total securities available-for-sale $ 9,975,109 $ 907,743 $ 9,061,790 $ 5,576 Equity investments with readily determinable fair values $ 8,814 $ 8,814 $ — $ — Derivatives (1) : Equity warrants 3,771 — — 3,771 Interest rate and economic contracts 4,556 — 4,556 — Derivative liabilities 2,500 — 2,500 — Fair Value Measurements as of December 31, 2021 Measured on a Recurring Basis Total Level 1 Level 2 Level 3 (In thousands) Securities available-for-sale: Agency residential MBS $ 2,898,210 $ — $ 2,898,210 $ — Municipal securities 2,315,968 — 2,315,968 — Agency commercial MBS 1,688,967 — 1,688,967 — Agency residential CMOs 1,038,134 — 1,038,134 — U.S. Treasury securities 966,898 966,898 — — Corporate debt securities 527,094 — 527,094 — Private label commercial MBS 450,217 — 435,216 15,001 Collateralized loan obligations 385,362 — 385,362 — Private label residential CMOs 264,417 — 264,417 — Asset-backed securities 129,547 — 129,547 — SBA securities 29,644 — 29,644 — Total securities available-for-sale $ 10,694,458 $ 966,898 $ 9,712,559 $ 15,001 Equity investments with readily determinable fair values $ 28,578 $ 28,578 $ — $ — Derivatives (1) : Equity warrants 3,555 — — 3,555 Interest rate and economic contracts 2,509 — 2,509 — Derivative liabilities 931 — 931 — ____________________ (1) For information regarding derivative instruments, see Note 10.

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, 2022, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

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 standard 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 has established a cross-functional project team and implementation plan to facilitate the LIBOR transition. As of December 31, 2021, the Company permanently ceased originating any new loans or entering into any transaction that would increase its LIBOR-based exposure. For all new variable-rate and hybrid loans, the Company primarily offers Prime and SOFR as the variable-rate index, but may consider alternate rates such as the American Interbank Offered Rate (“Ameribor”) and others based on market conditions and/or the type of loan or financial instrument. The Company has completed its readiness efforts to identify loans and other financial instruments that are impacted by the discontinuance of LIBOR. The Company has also completed its review for fallback language contained in contracts for LIBOR-based loans and other financial instruments and has begun to execute a transition plan to amend those legacy contracts maturing after June 30, 2023 that do not have or have inadequate fallback language by adding fallback language or to convert the base rate of the contract to a SOFR-based rate or another rate or index offered by the Company. The Company will also continue to assess impacts to its operations, financial models, data and technology as part of our transition plan. The Company is currently evaluating the impact of this Update on its consolidated financial statements but does not expect it to have a material impact. Effective Effect on the Financial Statements Standard Description Date or Other Significant Matters ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers This standard requires that an entity (acquirer) recognizes and measures contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At acquisition date, an acquirer should account for the related revenue contracts with customers in accordance with Topic 606 as if it had originated the contracts. The acquirer should consider the terms of the acquired contracts, such as timing of payment, identify each performance obligation in the contracts and allocate the total transaction price to each identified performance obligation on a relative standalone selling price basis as of contract inception or contract modification to determine what should be recorded at the acquisition date. The amendments improve comparability by providing consistent recognition and measurement guidance for revenue contracts with customers whether they are acquired and not acquired in a business combination. The amendments should be applied prospectively to business combinations occurring on or after the effective date. Additionally, early adoption is permitted. January 1, 2023 The Company will apply the amendments prospectively to business combinations occurring on or after the effective date. This standard is not expected to have a material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Standards	Accounting Standards Adopted in 2022 Effective January 1, 2022, the Company partially adopted ASU 2022-02, “Financial Instruments – Credit Losses (Topic 326) ,” specifically the amendment related to the vintage disclosures, which requires creditors that are public entities to disclose current-period gross charge-offs by year of origination for financing receivables and net investments in leases within the scope of ASC 326-20, “Financial Instruments – Credit Losses – Measured at Amortized Cost.” The amendment also eliminates the disclosure of gross recoveries by year of origination previously presented in Example 15 in ASC 326-20-50-79, since it is not required under the guidance in ASC 326-20-50-6. The Company updated the vintage table disclosure in Note 4. Loans and Leases to present only current-period gross charge-offs by year of origination.

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 combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments), 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.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current period’s presentation format. On the consolidated statements of earnings, new lines are presented for "Dividends and gains (losses) on equity investments" and "Warrant income," as those categories exceeded the disclosure materiality threshold in the fourth quarter of 2021, which previously had been included as part of "Other income.

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 15. 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, 2022, the fair value of these investments was $50.6 million.

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 standard 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 has established a cross-functional project team and implementation plan to facilitate the LIBOR transition. As of December 31, 2021, the Company permanently ceased originating any new loans or entering into any transaction that would increase its LIBOR-based exposure. For all new variable-rate and hybrid loans, the Company primarily offers Prime and SOFR as the variable-rate index, but may consider alternate rates such as the American Interbank Offered Rate (“Ameribor”) and others based on market conditions and/or the type of loan or financial instrument. The Company has completed its readiness efforts to identify loans and other financial instruments that are impacted by the discontinuance of LIBOR. The Company has also completed its review for fallback language contained in contracts for LIBOR-based loans and other financial instruments and has begun to execute a transition plan to amend those legacy contracts maturing after June 30, 2023 that do not have or have inadequate fallback language by adding fallback language or to convert the base rate of the contract to a SOFR-based rate or another rate or index offered by the Company. The Company will also continue to assess impacts to its operations, financial models, data and technology as part of our transition plan. The Company is currently evaluating the impact of this Update on its consolidated financial statements but does not expect it to have a material impact. Effective Effect on the Financial Statements Standard Description Date or Other Significant Matters ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers This standard requires that an entity (acquirer) recognizes and measures contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. At acquisition date, an acquirer should account for the related revenue contracts with customers in accordance with Topic 606 as if it had originated the contracts. The acquirer should consider the terms of the acquired contracts, such as timing of payment, identify each performance obligation in the contracts and allocate the total transaction price to each identified performance obligation on a relative standalone selling price basis as of contract inception or contract modification to determine what should be recorded at the acquisition date. The amendments improve comparability by providing consistent recognition and measurement guidance for revenue contracts with customers whether they are acquired and not acquired in a business combination. The amendments should be applied prospectively to business combinations occurring on or after the effective date. Additionally, early adoption is permitted. January 1, 2023 The Company will apply the amendments prospectively to business combinations occurring on or after the effective date. This standard is not expected to have a material impact on the Company’s consolidated financial statements.
