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 74 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 innovative 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. We have completed 29 acquisitions from May 1, 2000 through March 31, 2020 with our last acquisition in October 2017. Our acquisitions have been accounted for using the acquisition method of accounting and, accordingly, the operating results of the acquired entities have been included in the consolidated financial statements from their respective acquisition dates. 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 Report on Form 10-K for the year ended December 31, 2019 as filed with the Securities and Exchange Commission ("Form 10-K"). Updates to our significant accounting policies described below reflect the impact of the adoption of ASU 2016-13, “ Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments ” and the related amendments, commonly referred to as CECL. Investment Securities Prior to January 1, 2020, debt securities available-for-sale were measured at fair value and declines in the fair value were reviewed to determine whether the impairment was other-than-temporary. If we did not expect to recover the entire amortized cost basis of the security, then an other-than-temporary impairment was considered to have occurred. The cost basis of the security was written down to its estimated fair value and the amount of the write-down was recognized through a charge to earnings. If the amount of the amortized cost basis expected to be recovered increased in a future period, the cost basis of the security was not increased but rather recognized prospectively through interest income. Effective January 1, 2020, upon the adoption of ASU 2016-13, debt securities available-for-sale are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an available-for-sale debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit losses by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components of the fair value decline (if any). If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation reserve would be reduced, but not more than the amount of the current existing reserve for that security. Purchased Loans with Credit Deterioration Prior to January 1, 2020, purchased credit impaired loans were accounted for in accordance with ASC Subtopic 310-30, “ Loans and Debt Securities Acquired with Deteriorated Credit Quality.” At the time of acquisition, these loans were recorded at estimated fair value based upon estimated future cash flows with no related allowance for credit losses. Effective January 1, 2020, upon the adoption of ASU 2016-13, an entity records purchased financial assets with credit deterioration ("PCD assets") at the purchase price plus the allowance for credit losses expected at the time of acquisition. This allowance is recognized through a gross-up that increases the amortized cost basis of the asset with no effect on net income. Subsequent changes (favorable and unfavorable) in expected cash flows are recognized immediately in net income by adjusting the related allowance. Allowance for Credit Losses on Loans and Leases Held for Investment Effective January 1, 2020, upon the adoption of ASU 2016-13, the Company replaced the current incurred loss accounting model with the current expected credit loss ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The allowance for credit losses on loans and leases held for investment is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for loan and lease losses is reported as a reduction of the amortized cost basis of loans and leases, while the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the condensed consolidated balance sheets. The amortized cost basis of loans and leases does not include interest receivable, which is included in "Other assets" on the condensed consolidated balance sheets. The "Provision for credit losses" on the condensed consolidated statements of earnings (loss) is a combination of the provision for loan and lease losses and the provision for unfunded loan commitments. Under the CECL methodology, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of prepayments and considering available information about the collectability of cash flows, including information about relevant historical experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. Thus, the CECL methodology incorporates a broad range of information in developing credit loss estimates. The resulting allowance for loan and lease losses is deducted from the associated amortized cost basis to reflect the net amount expected to be collected. Subsequent changes in this estimate are recorded through the provision for credit losses and the allowance. The CECL methodology could result in significant changes to both the timing and amounts of provision for credit losses and the allowance as compared to recent historical periods. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for credit losses and recoveries on loans and leases previously charged off are added to the allowance. The allowance for loan and lease losses has an individually evaluated component for loans and leases that no longer share similar risk characteristics with other loans and leases and a pooled loans component for loans and leases that share similar risk characteristics. A loan or lease with an outstanding balance greater than $250,000 is individually evaluated for expected credit loss when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We select loans and leases for individual assessment on an ongoing basis using certain criteria such as payment performance, borrower reported financial results and budgets, and other external factors when appropriate. We measure the current expected credit loss of a loan or lease based upon the fair value of the underlying collateral if the loan or lease is collateral-dependent or the present value of cash flows, discounted at the effective interest rate, if the loan or lease is not collateral-dependent. To the extent a loan or lease balance exceeds the estimated collectable value, a reserve or charge-off is recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan is collateral-dependent. Our CECL methodology for the pooled loans component includes both quantitative and qualitative loss factors which are applied to our population of loans and leases and assessed at a pool level. The loan portfolio is segmented into four loan segments, eight loan classes and 22 loan pools based upon loan type that share similar default risk characteristics to calculate quantitative loss factors for each pool. Six of these loan pools have insignificant current balances and/or insignificant historical losses, thus, estimated losses are calculated using historical loss rates from the first quarter of 2009 to the current period rather than econometric regression modeling. For the remaining 16 loan pools, we estimate the probability of default (“PD”) during the reasonable and supportable period using seven econometric regression models developed to correlate macroeconomic variables to credit performance (including risk rating upgrades/downgrades and defaults). The loans and unfunded commitments are grouped into nine loss given default (“LGD”) pools based on portfolio classes that share similar collateral risk characteristics. LGD rates are computed based on the net charge-offs recognized divided by the exposure at default (“EAD”) of defaulted loans starting with the first quarter of 2009 to the current period. The PD and LGD rates are applied to the EAD at the loan or lease level based on contractual scheduled payments, estimated prepayments, and estimated usage of unfunded commitments to compute the current expected credit loss. We are using our actual historical loan prepayment experience from 2009 - 2018 to estimate future prepayments by loan pool. Prepayment rates during the reasonable and supportable period are based on historical experience from 2017-2018 as it exhibits economic conditions most similar to the single scenario baseline forecast discussed below. For the reasonable and supportable forecast period, future macroeconomic events and circumstances are estimated over a 4-quarter time horizon using a single scenario baseline forecast that is consistent with management's current expectations for the 16 loan pools. We use economic forecasts from Moody's Analytics in this process. The economic forecast is updated monthly therefore the one used for each quarter-end calculation is generally based on a one-month lag based on the timing of when the forecast becomes available. The key macroeconomic assumptions used in the PD regression models include at least three of the following economic indicators; Real GDP, Unemployment Rates, CRE Price Index and the BBB spread. The quantitative CECL model, utilizing historical portfolio performance, current portfolio composition and performance, estimated prepayments, and the effects of the economic forecast, calculates the expected EAD which is multiplied by the PD and LGD rates to calculate expected losses through the end of the forecast period. We then use a 2-quarter reversion period to revert on a straight-line basis from the PD, LGD, and prepayment rates used during the reasonable and support period to the Company’s historical PD, LGD, and prepayment experience. Subsequent to the reversion period for the remaining contractual life of loans and leases, PD and prepayment rates are based on historical experience from the first quarter of 2009 to the fourth quarter of 2018, which are updated on an annual basis or more frequently if necessary, while LGD rates are based on historical experience from the first quarter of 2009 to the current period. The PDs and LGDs calculated by the quantitative models are highly correlated to our internal risk ratings assigned to each loan and lease. To ensure the accuracy of our credit risk ratings, an independent credit review function assesses the appropriateness of the credit risk ratings assigned to loans and leases on a regular basis. The credit risk ratings assigned to every loan and lease are either “high pass,” “pass,” “special mention,” “substandard,” or “doubtful” as defined as follows: • High Pass : (Risk ratings 1-2) Loans and leases rated as "high pass" exhibit a favorable credit profile and have minimal risk characteristics. Repayment in full is expected, even in adverse economic conditions. • Pass: (Risk ratings 3-4) Loans and leases rated as "pass" are not adversely classified and collection and repayment in full are expected. • Special Mention : (Risk rating 5) Loans and leases rated as "special mention" have a potential weakness that requires management's attention. If not addressed, these potential weaknesses may result in further deterioration in the borrower's ability to repay the loan or lease. • Substandard : (Risk rating 6) Loans and leases rated as "substandard" have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the possibility that we will sustain some loss if the weaknesses are not corrected. • Doubtful : (Risk rating 7) Loans and leases rated as "doubtful" have all the weaknesses of those rated as "substandard," with the additional trait that the weaknesses make collection or repayment in full highly questionable and improbable. In addition, we may refer to the loans and leases with assigned credit risk ratings of "substandard" and "doubtful" together as "classified" loans and leases. For further information on classified loans and leases, see Note 4. Loans and Leases of the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)." In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company’s loan and lease risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in increases in the provisions for credit losses and the allowance for credit losses. The qualitative portion of the reserve on pooled loans and leases represents management’s judgment of additional considerations to account for internal and external risk factors that are not adequately measured in the quantitative reserve. The qualitative loss factors consider idiosyncratic risk factors, conditions that may not be reflected in quantitatively derived results, or other relevant factors to ensure the allowance for credit losses reflects our best estimate of current expected credit losses. Current and forecasted economic trends and underlying market values for collateral dependent loans are generally considered to be encompassed within our CECL quantitative methodology and component of the reserve. An incremental qualitative adjustment may be considered when economic forecasts exhibit higher levels of volatility or uncertainty. The other qualitative criteria we consider when establishing the loss factors include the following: • legal and regulatory matters that could impact our borrowers’ ability to repay our loans and leases; • loan and lease portfolio composition and any loan concentrations; • current lending policies and the effects of any new policies or policy amendments; • loan and lease production volume and mix; • loan and lease portfolio credit performance trends; • results of independent credit review; and • changes in management related to credit administration functions. We estimate the reserve for unfunded loan commitments using the same loss factors as used for the allowance for loan and lease losses. The reserve for unfunded loan commitments is computed using expected future utilization rates of the unfunded commitments during the contractual life of the commitments based on historical usage of unfunded commitments for the various loan types from the first quarter of 2015 to the second quarter of 2019. The utilization rates are updated on an annual basis. Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and the credit risk ratings and inherent loss rates currently assigned are reasonable and appropriate as of the reporting date. It is possible that others, given the same information, may at any point in time reach different conclusions that could result in a significant impact to the Company's financial statements. In addition, current credit risk ratings are subject to change as we continue to monitor our loans and leases. To the extent we experience increased levels of borrower loan defaults, borrowers’ noncompliance with our loan agreements, adverse changes in collateral values, or changes in economic and business conditions that adversely affect our borrowers, our classified loans and leases may increase. Higher levels of classified loans and leases generally result in increased provisions for credit losses and an increased allowance for credit losses. In addition, economic forecasts utilized in the estimation process will change in future periods, which will result in changes to the estimates made for current expected credit losses as of a point in time. However, economic forecasts are just one of many assumptions and components that go into estimating the allowance for credit losses. The CECL methodology requires a significant amount of management judgment in determining the appropriate allowance for credit losses. Most of the steps in the methodology involve judgment and are subjective in nature including, among other things, selection of the most reliable econometric regression models, segmentation of the loan and lease portfolio, determining the amount of loss history to consider, determining the relevant macroeconomic inputs to the quantitative models, determining the methodology to forecast prepayments, selection of the most appropriate economic forecast scenario, determining the length of the reasonable and supportable forecast and reversion periods, determining expected utilization rates on unfunded loan commitments and determining relevant and appropriate qualitative factors. In addition, the CECL methodology is dependent on economic forecasts which are inherently imprecise and will change from period to period. Although we have established an allowance for credit losses that we consider appropriate, there can be no assurance that the allowance will be sufficient to absorb future losses. Accounting Standards Adopted in 2020 Effective January 1, 2020, the Company adopted ASU 2016-13 and the related amendments to ASC Topic 326, “ Financial Instruments - Credit Losses ,” to replace the current incurred loss accounting model with a current expected credit loss approach for financial instruments measured at amortized cost and other commitments to extend credit. The new standard is generally intended to require earlier recognition of credit losses. While the standard changes the measurement of the allowance for credit losses, it does not change the credit risk of our lending portfolios or the ultimate losses in those portfolios. Under the CECL approach, the standard requires immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The standard modifies the other-than-temporary impairment model for available-for-sale debt securities to require entities to record an allowance when recognizing credit losses for available-for-sale securities, rather than reducing the amortized cost of the securities by direct write-offs. The Company adopted the new standard using the modified retrospective approach and recognized a cumulative effect adjustment to decrease retained earnings by $5.3 million , net of taxes, and increase the allowance for credit losses by $7.3 million without restating prior periods and applied the requirements of the new standard prospectively. There was no cumulative effect adjustment related to available-for-sale securities at adoption. The Company elected to account for interest receivable separately from the amortized cost of loans and leases and investment securities and is included in "Other assets" on the condensed consolidated balance sheets. The Company elected the practical expedient to use the fair value of the collateral at the reporting date when recording the net carrying amount of the asset and determining the allowance for credit losses for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the entity’s assessment as of the reporting date (collateral dependent financial asset). Additionally, the Company implemented new business processes, new internal controls, and modified existing and/or implemented new internal models and tools to facilitate the ongoing application of the new guidance. See Note 4. Loans and Leases for further details. Effective January 1, 2020, the Company adopted ASU 2017-04, " Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment " which simplifies goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge would be recognized for any amount by which the carrying amount exceeds the reporting unit's fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. The Company used this approach to evaluate its goodwill during the first quarter of 2020, as an unprecedented decline in economic conditions triggered by the Coronavirus Disease ("COVID-19") pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These events indicated that goodwill may be impaired and resulted in us performing a goodwill impairment assessment. As a result, a goodwill impairment charge of $1.47 billion was recorded as the Company's estimated fair value was less than its book value. Effective January 1, 2020, the Company adopted the provisions of ASU 2018-13, " Fair Value Measurement (Topic 820): Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurements " which add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty. Although the guidance modifies our disclosures in 2020, there was no impact to our condensed consolidated financial statements from the adoption of this new standard. ASU 2020-03, " Codification Improvements to Financial Instruments " ("ASU 2020-03"), revised a wide variety of topics in the Codification with the intent to make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. ASU 2020-03 was effective immediately upon its release in March 2020 and did not have a material impact to our 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, the realization of deferred tax assets, and the fair value estimates of assets acquired and liabilities assumed in acquisitions. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant. Reclassifications

We concluded their 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 we owned and third party guarantees, if any, to assess whether an unrealized loss was credit-related. Accordingly, we determined the unrealized losses were not credit-related and, therefore, we recognized such impairment 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, 2020 Amortized Fair Maturities Cost Value (In thousands) Due in one year or less $ 9,898 $ 10,026 Due after one year through five years 300,638 309,312 Due after five years through ten years 975,907 1,024,183 Due after ten years 2,345,123 2,414,142 Total securities available-for-sale $ 3,631,566 $ 3,757,663 Mortgage-backed securities have contractual maturity dates, but require periodic payments based upon scheduled amortization terms.

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.

The higher provision for loan and lease losses in the first quarter of 2020 was a result of the current economic forecast, which reflected a significant deterioration in key macro-economic forecast variables such as unemployment and Real GDP as a result of the COVID-19 pandemic, significant loan downgrades into special mention, and higher provisions on individually evaluated loans. 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 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 implied 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 unprecedented decline in economic conditions triggered by the COVID-19 pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These events indicated that goodwill may be impaired and resulted in us performing a goodwill impairment assessment. As a result, we recorded a goodwill impairment charge of $1.47 billion as our estimated fair value was less than our book value. This was a non-cash charge to earnings and had no impact on our regulatory capital ratios, cash flows, or liquidity position. The following table presents the changes in the carrying amount of goodwill for the period indicated: Goodwill (In thousands) Balance, December 31, 2019 $ 2,548,670 Impairment (1,470,000 ) Balance, March 31, 2020 $ 1,078,670 Our other intangible assets with definite lives include 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 aggregate amortization expense is expected to be $14.8 million for 2020 . The estimated aggregate amortization expense related to our current intangible assets for each of the next four years is $10.8 million for 2021 , $7.4 million for 2022 , $3.8 million for 2023 , and $1.7 million for 2024 . Our current intangible assets are estimated to be fully amortized by the end of 2024.

Derivatives [Abstract]
Derivatives Not Designated as Hedging Instruments	NOTE 10. DERIVATIVES The Company uses derivatives to manage exposure to market risk, primarily foreign currency risk and interest rate risk, and to assist customers with their risk management objectives. The Company uses foreign exchange contracts to manage the foreign exchange rate risk associated with certain foreign currency-denominated assets and liabilities. As of March 31, 2020 , all of our derivatives were held for risk management purposes and none were designated as accounting hedges. The objective is to manage the uncertainty of future foreign exchange rate fluctuations. These derivatives provide for a fixed exchange rate which has the effect of reducing or eliminating changes to anticipated cash flows to be received on assets and liabilities denominated in foreign currencies as the result of changes to exchange rates. Our derivatives are carried at fair value and recorded in other assets or other liabilities, as appropriate. The changes in fair value of our derivatives and the related interest are recognized in "Noninterest income - other" in the condensed consolidated statements of earnings (loss). For the three months ended March 31, 2020 , changes in fair value recorded through noninterest income in the condensed consolidated statements of earnings (loss) were immaterial. In connection with negotiated credit facilities and certain other services, we may obtain equity warrant assets giving us the right to acquire stock in primarily private, venture-backed companies. We hold these assets for prospective investment gains. We do not use them to hedge any economic risks nor do we use other derivative instruments to hedge economic risks stemming from equity warrant assets. We account for equity warrant assets as derivatives when they contain net settlement terms and other qualifying criteria under ASC 815. These equity warrant assets are recorded at estimated fair value and are classified as "Other assets" on our condensed consolidated balance sheets at the time they are obtained. See Note 7. Other Assets . Derivative instruments expose us to credit risk in the event of nonperformance by counterparties. This risk exposure consists primarily of the termination value of agreements where we are in a favorable position. We manage the credit risk associated with various derivative agreements through counterparty credit review and monitoring procedures. The following table presents the U.S. dollar notional amounts and fair values of our derivative instruments included in the condensed consolidated balance sheets as of the dates indicated: March 31, 2020 December 31, 2019 Notional Fair Notional Fair Derivatives Not Designated As Hedging Instruments Amount Value Amount Value (In thousands) Derivative Assets: Interest rate contracts $ 10,932 $ 120 $ 15,159 $ 71 Foreign exchange contracts 90,122 4,826 91,144 1,163 Other derivative assets 101,054 4,946 106,303 1,234 Equity warrant assets 26,469 4,290 26,079 3,434 Total $ 127,523 $ 9,236 $ 132,382 $ 4,668 Derivative Liabilities: Interest rate contracts $ 10,932 $ 120 $ 15,159 $ 71 Foreign exchange contracts 90,122 1,032 91,144 684 Total $ 101,054 $ 1,152 $ 106,303 $ 755

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. 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 with us under these arrangements. In addition, we invest in small business investment companies that call for capital contributions up to an amount specified in the partnership agreements, and in CRA-related loan pools. As of March 31, 2020 and December 31, 2019 , we had commitments to contribute capital to these entities totaling $50.5 million and $40.7 million . We also had commitments to contribute up to an additional $50,000 to private equity funds at March 31, 2020 and December 31, 2019 . 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, 2020 (In thousands) Period ending December 31, 2020 $ 31,698 2021 18,820 Total $ 50,518 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 ASC Topic 820, “ Fair Value Measurement ,” defines fair value, establishes a framework for measuring fair value including a three‑level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2: Observable inputs other than Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the financial instrument. This category generally includes agency residential CMOs, agency commercial and residential MBS, municipal securities, collateralized loan obligations, registered publicly rated private label CMOs, corporate debt securities, SBA securities, and asset-backed securitizations. • Level 3: Inputs to a valuation methodology that are unobservable, supported by little or no market activity, and significant to the fair value measurement. These valuation methodologies generally include pricing models, discounted cash flow models, or a determination of fair value that requires significant management judgment or estimation. This category also includes observable inputs from a pricing service not corroborated by observable market data, and includes our non-rated private label CMOs, non-rated private label asset-backed securities, and equity warrants. 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. 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, 2020 Measured on a Recurring Basis Total Level 1 Level 2 Level 3 (In thousands) Securities available‑for‑sale: Agency commercial MBS $ 1,125,432 $ — $ 1,125,432 $ — Agency residential CMOs 1,102,097 — 1,102,097 — Municipal securities 733,884 — 733,884 — Agency residential MBS 289,831 — 289,831 — Asset-backed securities 210,699 — 196,080 14,619 Collateralized loan obligations 130,082 — 130,082 — Private label residential CMOs 97,862 — 92,920 4,942 SBA securities 45,441 — 45,441 — Corporate debt securities 16,957 — 16,957 — U.S. Treasury securities 5,378 5,378 — — Total securities available-for-sale $ 3,757,663 $ 5,378 $ 3,732,724 $ 19,561 Equity investments with readily determinable fair values $ 2,471 $ 2,471 $ — $ — Derivatives (1) : Equity warrants 4,290 — — 4,290 Other derivative assets 4,946 — 4,946 — Derivative liabilities 1,152 — 1,152 — Fair Value Measurements as of December 31, 2019 Measured on a Recurring Basis Total Level 1 Level 2 Level 3 (In thousands) Securities available‑for‑sale: Agency commercial MBS $ 1,108,224 $ — $ 1,108,224 $ — Agency residential CMOs 1,136,397 — 1,136,397 — Municipal securities 735,159 — 735,159 — Agency residential MBS 305,198 — 305,198 — Asset-backed securities 214,783 — 198,348 16,435 Collateralized loan obligations 123,756 — 123,756 — Private label residential CMOs 99,483 — 93,219 6,264 SBA securities 48,258 — 48,258 — Corporate debt securities 20,748 — 20,748 — U.S. Treasury securities 5,181 5,181 — — Total securities available-for-sale $ 3,797,187 $ 5,181 $ 3,769,307 $ 22,699 Equity investments with readily determinable fair values $ 2,998 $ 2,998 $ — $ — Derivatives (1) : Equity warrants 3,434 — — 3,434 Other derivative assets 1,234 — 1,234 — Derivative liabilities 755 — 755 — ____________________ (1) For information regarding derivative instruments, see Note 10.

Nature of Operations and Summary of Significant Accounting Policies, and Note 14. Fair Value Measurements, to the Consolidated Financial Statements of the Company's 2019 Annual Report on Form 10-K. Limitations Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. 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, 2020 , 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, 2020 , there were 2,343,255 shares available for grant under the 2017 Plan. Though frozen for new issuances, certain awards issued under the 2003 Stock Incentive Plan remain outstanding, but are due to vest no later than February 2021. Restricted Stock Restricted stock amortization totaled $6.5 million and $5.8 million for the three months ended March 31, 2020 and 2019 . 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, 2020 totaled $54.3 million . Time-Based Restricted Stock Awards At March 31, 2020 , there were 1,436,957 shares of unvested TRSAs outstanding pursuant to the Company's 2003 and 2017 Stock Incentive Plans. The TRSAs generally vest ratably over a service period of three to 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 stock on the award date and is recognized over the vesting period using the straight‑line method. Performance-Based Restricted Stock Units At March 31, 2020 , there were 338,836 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 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. Compensation expense related to PRSUs is based on the fair value of the underlying stock on the award date and is amortized over the vesting period using the straight-line method unless it is determined that: (1) attainment of the financial metrics is less than probable, in which case a portion of the amortization is suspended, or (2) attainment of the financial metrics is improbable, in which case a portion of the previously recognized amortization is reversed and also suspended. If it is determined that attainment of a financial measure higher than target is probable, the amortization will increase to up to 150% or 200%

January 1, 2021 The adoption of this guidance is not expected to have a material 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)" 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. This Update also provides numerous optional expedients for derivative accounting. An entity may elect to apply this Update for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. We anticipate that ASU 2020-04 will simplify any modifications we execute between the selected start date (not yet determined) and December 31, 2022 that are directly related to LIBOR transition. March 12, 2020 through December 31, 2022 The adoption of this guidance is not expected to have a material impact on the Company’s condensed consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Significant Accounting Policies	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 Report on Form 10-K for the year ended December 31, 2019 as filed with the Securities and Exchange Commission ("Form 10-K"). Updates to our significant accounting policies described below reflect the impact of the adoption of ASU 2016-13, “ Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments ” and the related amendments, commonly referred to as CECL. Investment Securities Prior to January 1, 2020, debt securities available-for-sale were measured at fair value and declines in the fair value were reviewed to determine whether the impairment was other-than-temporary. If we did not expect to recover the entire amortized cost basis of the security, then an other-than-temporary impairment was considered to have occurred. The cost basis of the security was written down to its estimated fair value and the amount of the write-down was recognized through a charge to earnings. If the amount of the amortized cost basis expected to be recovered increased in a future period, the cost basis of the security was not increased but rather recognized prospectively through interest income. Effective January 1, 2020, upon the adoption of ASU 2016-13, debt securities available-for-sale are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an available-for-sale debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit losses by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components of the fair value decline (if any). If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation reserve would be reduced, but not more than the amount of the current existing reserve for that security. Purchased Loans with Credit Deterioration Prior to January 1, 2020, purchased credit impaired loans were accounted for in accordance with ASC Subtopic 310-30, “ Loans and Debt Securities Acquired with Deteriorated Credit Quality.” At the time of acquisition, these loans were recorded at estimated fair value based upon estimated future cash flows with no related allowance for credit losses. Effective January 1, 2020, upon the adoption of ASU 2016-13, an entity records purchased financial assets with credit deterioration ("PCD assets") at the purchase price plus the allowance for credit losses expected at the time of acquisition. This allowance is recognized through a gross-up that increases the amortized cost basis of the asset with no effect on net income. Subsequent changes (favorable and unfavorable) in expected cash flows are recognized immediately in net income by adjusting the related allowance. Allowance for Credit Losses on Loans and Leases Held for Investment Effective January 1, 2020, upon the adoption of ASU 2016-13, the Company replaced the current incurred loss accounting model with the current expected credit loss ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The allowance for credit losses on loans and leases held for investment is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for loan and lease losses is reported as a reduction of the amortized cost basis of loans and leases, while the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the condensed consolidated balance sheets. The amortized cost basis of loans and leases does not include interest receivable, which is included in "Other assets" on the condensed consolidated balance sheets. The "Provision for credit losses" on the condensed consolidated statements of earnings (loss) is a combination of the provision for loan and lease losses and the provision for unfunded loan commitments. Under the CECL methodology, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of prepayments and considering available information about the collectability of cash flows, including information about relevant historical experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. Thus, the CECL methodology incorporates a broad range of information in developing credit loss estimates. The resulting allowance for loan and lease losses is deducted from the associated amortized cost basis to reflect the net amount expected to be collected. Subsequent changes in this estimate are recorded through the provision for credit losses and the allowance. The CECL methodology could result in significant changes to both the timing and amounts of provision for credit losses and the allowance as compared to recent historical periods. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for credit losses and recoveries on loans and leases previously charged off are added to the allowance. The allowance for loan and lease losses has an individually evaluated component for loans and leases that no longer share similar risk characteristics with other loans and leases and a pooled loans component for loans and leases that share similar risk characteristics. A loan or lease with an outstanding balance greater than $250,000 is individually evaluated for expected credit loss when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We select loans and leases for individual assessment on an ongoing basis using certain criteria such as payment performance, borrower reported financial results and budgets, and other external factors when appropriate. We measure the current expected credit loss of a loan or lease based upon the fair value of the underlying collateral if the loan or lease is collateral-dependent or the present value of cash flows, discounted at the effective interest rate, if the loan or lease is not collateral-dependent. To the extent a loan or lease balance exceeds the estimated collectable value, a reserve or charge-off is recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan is collateral-dependent. Our CECL methodology for the pooled loans component includes both quantitative and qualitative loss factors which are applied to our population of loans and leases and assessed at a pool level. The loan portfolio is segmented into four loan segments, eight loan classes and 22 loan pools based upon loan type that share similar default risk characteristics to calculate quantitative loss factors for each pool. Six of these loan pools have insignificant current balances and/or insignificant historical losses, thus, estimated losses are calculated using historical loss rates from the first quarter of 2009 to the current period rather than econometric regression modeling. For the remaining 16 loan pools, we estimate the probability of default (“PD”) during the reasonable and supportable period using seven econometric regression models developed to correlate macroeconomic variables to credit performance (including risk rating upgrades/downgrades and defaults). The loans and unfunded commitments are grouped into nine loss given default (“LGD”) pools based on portfolio classes that share similar collateral risk characteristics. LGD rates are computed based on the net charge-offs recognized divided by the exposure at default (“EAD”) of defaulted loans starting with the first quarter of 2009 to the current period. The PD and LGD rates are applied to the EAD at the loan or lease level based on contractual scheduled payments, estimated prepayments, and estimated usage of unfunded commitments to compute the current expected credit loss. We are using our actual historical loan prepayment experience from 2009 - 2018 to estimate future prepayments by loan pool. Prepayment rates during the reasonable and supportable period are based on historical experience from 2017-2018 as it exhibits economic conditions most similar to the single scenario baseline forecast discussed below. For the reasonable and supportable forecast period, future macroeconomic events and circumstances are estimated over a 4-quarter time horizon using a single scenario baseline forecast that is consistent with management's current expectations for the 16 loan pools. We use economic forecasts from Moody's Analytics in this process. The economic forecast is updated monthly therefore the one used for each quarter-end calculation is generally based on a one-month lag based on the timing of when the forecast becomes available. The key macroeconomic assumptions used in the PD regression models include at least three of the following economic indicators; Real GDP, Unemployment Rates, CRE Price Index and the BBB spread. The quantitative CECL model, utilizing historical portfolio performance, current portfolio composition and performance, estimated prepayments, and the effects of the economic forecast, calculates the expected EAD which is multiplied by the PD and LGD rates to calculate expected losses through the end of the forecast period. We then use a 2-quarter reversion period to revert on a straight-line basis from the PD, LGD, and prepayment rates used during the reasonable and support period to the Company’s historical PD, LGD, and prepayment experience. Subsequent to the reversion period for the remaining contractual life of loans and leases, PD and prepayment rates are based on historical experience from the first quarter of 2009 to the fourth quarter of 2018, which are updated on an annual basis or more frequently if necessary, while LGD rates are based on historical experience from the first quarter of 2009 to the current period. The PDs and LGDs calculated by the quantitative models are highly correlated to our internal risk ratings assigned to each loan and lease. To ensure the accuracy of our credit risk ratings, an independent credit review function assesses the appropriateness of the credit risk ratings assigned to loans and leases on a regular basis. The credit risk ratings assigned to every loan and lease are either “high pass,” “pass,” “special mention,” “substandard,” or “doubtful” as defined as follows: • High Pass : (Risk ratings 1-2) Loans and leases rated as "high pass" exhibit a favorable credit profile and have minimal risk characteristics. Repayment in full is expected, even in adverse economic conditions. • Pass: (Risk ratings 3-4) Loans and leases rated as "pass" are not adversely classified and collection and repayment in full are expected. • Special Mention : (Risk rating 5) Loans and leases rated as "special mention" have a potential weakness that requires management's attention. If not addressed, these potential weaknesses may result in further deterioration in the borrower's ability to repay the loan or lease. • Substandard : (Risk rating 6) Loans and leases rated as "substandard" have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the possibility that we will sustain some loss if the weaknesses are not corrected. • Doubtful : (Risk rating 7) Loans and leases rated as "doubtful" have all the weaknesses of those rated as "substandard," with the additional trait that the weaknesses make collection or repayment in full highly questionable and improbable. In addition, we may refer to the loans and leases with assigned credit risk ratings of "substandard" and "doubtful" together as "classified" loans and leases. For further information on classified loans and leases, see Note 4. Loans and Leases of the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)." In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company’s loan and lease risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in increases in the provisions for credit losses and the allowance for credit losses. The qualitative portion of the reserve on pooled loans and leases represents management’s judgment of additional considerations to account for internal and external risk factors that are not adequately measured in the quantitative reserve. The qualitative loss factors consider idiosyncratic risk factors, conditions that may not be reflected in quantitatively derived results, or other relevant factors to ensure the allowance for credit losses reflects our best estimate of current expected credit losses. Current and forecasted economic trends and underlying market values for collateral dependent loans are generally considered to be encompassed within our CECL quantitative methodology and component of the reserve. An incremental qualitative adjustment may be considered when economic forecasts exhibit higher levels of volatility or uncertainty. The other qualitative criteria we consider when establishing the loss factors include the following: • legal and regulatory matters that could impact our borrowers’ ability to repay our loans and leases; • loan and lease portfolio composition and any loan concentrations; • current lending policies and the effects of any new policies or policy amendments; • loan and lease production volume and mix; • loan and lease portfolio credit performance trends; • results of independent credit review; and • changes in management related to credit administration functions. We estimate the reserve for unfunded loan commitments using the same loss factors as used for the allowance for loan and lease losses. The reserve for unfunded loan commitments is computed using expected future utilization rates of the unfunded commitments during the contractual life of the commitments based on historical usage of unfunded commitments for the various loan types from the first quarter of 2015 to the second quarter of 2019. The utilization rates are updated on an annual basis. Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and the credit risk ratings and inherent loss rates currently assigned are reasonable and appropriate as of the reporting date. It is possible that others, given the same information, may at any point in time reach different conclusions that could result in a significant impact to the Company's financial statements. In addition, current credit risk ratings are subject to change as we continue to monitor our loans and leases. To the extent we experience increased levels of borrower loan defaults, borrowers’ noncompliance with our loan agreements, adverse changes in collateral values, or changes in economic and business conditions that adversely affect our borrowers, our classified loans and leases may increase. Higher levels of classified loans and leases generally result in increased provisions for credit losses and an increased allowance for credit losses. In addition, economic forecasts utilized in the estimation process will change in future periods, which will result in changes to the estimates made for current expected credit losses as of a point in time. However, economic forecasts are just one of many assumptions and components that go into estimating the allowance for credit losses. The CECL methodology requires a significant amount of management judgment in determining the appropriate allowance for credit losses. Most of the steps in the methodology involve judgment and are subjective in nature including, among other things, selection of the most reliable econometric regression models, segmentation of the loan and lease portfolio, determining the amount of loss history to consider, determining the relevant macroeconomic inputs to the quantitative models, determining the methodology to forecast prepayments, selection of the most appropriate economic forecast scenario, determining the length of the reasonable and supportable forecast and reversion periods, determining expected utilization rates on unfunded loan commitments and determining relevant and appropriate qualitative factors. In addition, the CECL methodology is dependent on economic forecasts which are inherently imprecise and will change from period to period. Although we have established an allowance for credit losses that we consider appropriate, there can be no assurance that the allowance will be sufficient to absorb future losses.
Recently Issued Accounting Standards	Accounting Standards Adopted in 2020 Effective January 1, 2020, the Company adopted ASU 2016-13 and the related amendments to ASC Topic 326, “ Financial Instruments - Credit Losses ,” to replace the current incurred loss accounting model with a current expected credit loss approach for financial instruments measured at amortized cost and other commitments to extend credit. The new standard is generally intended to require earlier recognition of credit losses. While the standard changes the measurement of the allowance for credit losses, it does not change the credit risk of our lending portfolios or the ultimate losses in those portfolios. Under the CECL approach, the standard requires immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The standard modifies the other-than-temporary impairment model for available-for-sale debt securities to require entities to record an allowance when recognizing credit losses for available-for-sale securities, rather than reducing the amortized cost of the securities by direct write-offs. The Company adopted the new standard using the modified retrospective approach and recognized a cumulative effect adjustment to decrease retained earnings by $5.3 million , net of taxes, and increase the allowance for credit losses by $7.3 million without restating prior periods and applied the requirements of the new standard prospectively. There was no cumulative effect adjustment related to available-for-sale securities at adoption. The Company elected to account for interest receivable separately from the amortized cost of loans and leases and investment securities and is included in "Other assets" on the condensed consolidated balance sheets. The Company elected the practical expedient to use the fair value of the collateral at the reporting date when recording the net carrying amount of the asset and determining the allowance for credit losses for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the entity’s assessment as of the reporting date (collateral dependent financial asset). Additionally, the Company implemented new business processes, new internal controls, and modified existing and/or implemented new internal models and tools to facilitate the ongoing application of the new guidance. See Note 4. Loans and Leases for further details. Effective January 1, 2020, the Company adopted ASU 2017-04, " Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment " which simplifies goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge would be recognized for any amount by which the carrying amount exceeds the reporting unit's fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. The Company used this approach to evaluate its goodwill during the first quarter of 2020, as an unprecedented decline in economic conditions triggered by the Coronavirus Disease ("COVID-19") pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These events indicated that goodwill may be impaired and resulted in us performing a goodwill impairment assessment. As a result, a goodwill impairment charge of $1.47 billion was recorded as the Company's estimated fair value was less than its book value. Effective January 1, 2020, the Company adopted the provisions of ASU 2018-13, " Fair Value Measurement (Topic 820): Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurements " which add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty. Although the guidance modifies our disclosures in 2020, there was no impact to our condensed consolidated financial statements from the adoption of this new standard. ASU 2020-03, " Codification Improvements to Financial Instruments " ("ASU 2020-03"), revised a wide variety of topics in the Codification with the intent to make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. ASU 2020-03 was effective immediately upon its release in March 2020 and did not have a material impact to our condensed consolidated financial statements. Effective Effect on the Financial Statements Standard Description Date or Other Significant Matters ASU 2020-01, "Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)" This Update clarifies the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting in Topic 323 and the accounting for certain forward contracts and purchased options accounted for under Topic 815. January 1, 2021 The adoption of this guidance is not expected to have a material 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)" 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. This Update also provides numerous optional expedients for derivative accounting. An entity may elect to apply this Update for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. We anticipate that ASU 2020-04 will simplify any modifications we execute between the selected start date (not yet determined) and December 31, 2022 that are directly related to LIBOR transition. March 12, 2020 through December 31, 2022 The adoption of this guidance is not expected to have a material impact on the Company’s condensed consolidated financial statements.
Basis of Presentation	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	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, the realization of deferred tax assets, and the fair value estimates of assets acquired and liabilities assumed in acquisitions. 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 condensed consolidated statements of earnings (loss), a new line is presented for "Customer related expense," as that category exceeded the disclosure materiality threshold in 2019, which previously had been included as part of "Other expense."

Fair Value Disclosures [Abstract]
Fair Value Measurement, Policy	FAIR VALUE MEASUREMENTS ASC Topic 820, “ Fair Value Measurement ,” defines fair value, establishes a framework for measuring fair value including a three‑level valuation hierarchy, and expands disclosures about fair value measurements. Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date reflecting assumptions that a market participant would use when pricing an asset or liability. The hierarchy uses three levels of inputs to measure the fair value of assets and liabilities as follows: • Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2: Observable inputs other than Level 1, including quoted prices for similar assets and liabilities in active markets, quoted prices in less active markets, or other observable inputs that can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the financial instrument. This category generally includes agency residential CMOs, agency commercial and residential MBS, municipal securities, collateralized loan obligations, registered publicly rated private label CMOs, corporate debt securities, SBA securities, and asset-backed securitizations. • Level 3: Inputs to a valuation methodology that are unobservable, supported by little or no market activity, and significant to the fair value measurement. These valuation methodologies generally include pricing models, discounted cash flow models, or a determination of fair value that requires significant management judgment or estimation. This category also includes observable inputs from a pricing service not corroborated by observable market data, and includes our non-rated private label CMOs, non-rated private label asset-backed securities, and equity warrants. 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.

January 1, 2021 The adoption of this guidance is not expected to have a material 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)" 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. This Update also provides numerous optional expedients for derivative accounting. An entity may elect to apply this Update for contract modifications as of January 1, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. We anticipate that ASU 2020-04 will simplify any modifications we execute between the selected start date (not yet determined) and December 31, 2022 that are directly related to LIBOR transition. March 12, 2020 through December 31, 2022 The adoption of this guidance is not expected to have a material impact on the Company’s condensed consolidated financial statements.
