Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of Pacific Premier Bancorp, Inc. (the “Corporation”) and its wholly owned subsidiaries, including Pacific Premier Bank (the “Bank”) (collectively, the “Company,” “we,” “our” or “us”). All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, the unaudited consolidated financial statements reflect all normal recurring adjustments that are necessary for a fair presentation of the results for the interim periods presented. The results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results that may be expected for any other interim period or the full year ending December 31, 2020 . Certain items in the prior year financial statements were reclassified to conform to the current year presentation. Reclassification had no effect on prior year net income or stockholders’ equity. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 (the “ 2019 Form 10-K”). The Company accounts for its investments in its wholly owned special purpose entities, Heritage Oaks Capital Trust II and Santa Lucia Bancorp (CA) Capital Trust, under the equity method whereby the subsidiary’s net earnings are recognized in the Company’s statement of income and the investment in these entities is included in Other Assets on the Company’s Consolidated Statements of Financial Condition. See Note 8 Subordinated Debentures for additional information.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Standards Adopted in 2020 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This Update replaces the incurred loss impairment model in current U.S. GAAP with a model that reflects current expected credit losses (“CECL”). The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. CECL also requires credit losses on available-for-sale debt securities be measured through an allowance for credit losses when the fair value is less than the amortized cost basis. It also applies to off-balance sheet credit exposures. The Update requires that all expected credit losses for financial assets held at the reporting date be measured based on historical experience, current conditions and reasonable and supportable forecasts. The Update also requires enhanced disclosure, including qualitative and quantitative disclosures that provide additional information about significant estimates and judgments used in estimating credit losses. The provisions of this Update became effective for the Company for all annual and interim periods beginning January 1, 2020. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . This Update was issued as part of an ongoing project on the FASB’s agenda for improving the Codification or correcting for its unintended application. The FASB issued this Update, which is specific to Updates: 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , and 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this Update became effective for all interim and annual reporting periods for the Company on January 1, 2020. The Company adopted the provisions within this Update in conjunction with the implementation of Accounting Standard Codification (“ASC”) 326, Financial Instruments - Credit Losses , as discussed below, including: (i) the election to not measure credit losses on accrued interest receivable when such balances are written-off in a timely manner when deemed uncollectable and (ii) the election to not include the balance of accrued interest receivable as part of the amortized cost of a loan, but rather to present it separately in the consolidated statements of financial position. In May 2019, the FASB issued ASU 2019-05, Financial Instruments - Credit Losses (Topic 326) - Targeted Transition Relief . This Update was issued to allow entities that have certain financial instruments within the scope of ASC 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost , to make an irrevocable election to elect the fair value option for those instruments in ASC 825-10, Financial Instruments - Overall upon the adoption of ASC 326, which for the Company was January 1, 2020. The fair value option is not applicable to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. The Company did not elect the fair value option for any of its financial assets upon the adoption of ASC 326 on January 1, 2020. The Company has developed an expected credit loss estimation model in accordance with ASC 326. The Company implemented the model through a cross-functional effort steered by a CECL Committee, related sub-committees and working groups. These committees, sub-committees and working groups, collectively, were primarily comprised of senior management and staff members from our finance, credit, lending, internal audit, risk management and IT functional areas. Depending on the nature of each identified pool of financial assets with similar risk characteristics, the Company employs the use of a probability of default (“PD”) and loss given default (“LGD”) discounted cash flow methodology for commercial real estate and commercial loans, and a loss-rate methodology for retail loans, in order to estimate expected future credit losses. The Company’s model incorporates reasonable and supportable economic forecasts into the estimate of expected credit losses, which requires significant judgment. Management leverages economic projections from a reputable and independent third party to inform its reasonable and supportable economic forecasts. Effective January 1, 2020, the Company adopted the provisions of ASC 326 through the application of the modified retrospective transition approach, and recorded a net decrease of $45.6 million to the beginning balance of retained earnings as of January 1, 2020 for the cumulative effect adjustment, reflecting an initial adjustment to the allowance for credit losses (“ACL”) of $64.0 million , net of related deferred tax assets arising from temporary differences of $18.3 million , commonly referred to as the “Day 1” adjustment. The Day 1 adjustment to the ACL is reflective of expected lifetime credit losses associated with the composition of financial assets within in the scope of ASC 326 as of January 1, 2020, which is comprised of loans held for investment and off-balance sheet credit exposures at January 1, 2020, as well as management’s current expectation of future economic conditions. Management did not have any qualitative adjustments as of January 1, 2020. The Day 1 adjustment was comprised of $55.7 million for loans held for investment and $8.3 million for off-balance sheet commitments for a total of $64.0 million . The Day 1 adjustment to the ACL for loans held for investment consists of $16.1 million for investor loans secured by real estate, $27.6 million for business real estate secured loans, $9.5 million for commercial loans and $2.5 million for retail loans. The majority of the Day 1 increase in the ACL for loans held for investment is attributable primarily to the life of loan loss impact and addition of an allowance on acquired loans based on the methodology discussed above and secondarily to the incorporation of reasonable and supportable economic forecasts into the estimate of expected future credit losses to our commercial real estate and commercial owner-occupied loan portfolios, which have commercial real estate as the primary collateral source and longer contractual maturities relative to our loan portfolio as a whole. Please also see Note 3 - Significant Accounting Policies , for a discussion on the Company’s accounting policy for the ACL, Note 6 - Loans Held for Investment and Note 7 - Allowance for Credit Losses , for additional information on the Company’s ACL, as well as other related disclosures. The Company’s assessment of held-to-maturity and available-for-sale investment securities as of January 1, 2020 indicated that an ACL was not required. The Company determined the likelihood of default on held-to-maturity investment securities was remote, and the amount of expected non-repayment on those investments was zero. The Company also analyzed available-for-sale investment securities that were in an unrealized loss position as of January 1, 2020 and determined the decline in fair value for those securities was not related to credit, but rather related to changes in interest rates and general market conditions. As such, no ACL was recorded for held-to-maturity and available-for-sale securities as of January 1, 2020. In accordance with ASC 326-10-65, upon the adoption of ASC 326, the Company did not reassess purchased loans with credit deterioration (previously classified as purchased credit impaired loans under ASC 310-30), as there were no such loans on January 1, 2020. Additionally, there were no investment securities with previously recorded other-than-temporary impairment as of January 1, 2020. As previously mentioned, in conjunction with the adoption of ASC 326, the Company made an accounting policy election not to measure an ACL on accrued interest receivables in accordance with ASC 326-20-30-5A. When accrued interest receivable is deemed to be uncollectable, the Company promptly reverses such balances through current period earnings in the period they are deemed uncollectable. Additionally, the Company has also elected not to include the balance of accrued interest receivable in the amortized cost basis of financial assets within the scope of ASC 326. Accrued interest receivable will continue to be presented separately in the consolidated financial statements. In February 2019, the U.S. federal bank regulatory agencies approved a final rule modifying their regulatory capital rules and providing an option to phase in over a three-year period the Day 1 adverse regulatory capital effects of ASU 2016-13. Additionally, in March 2020, the U.S. federal bank regulatory agencies issued an interim final rule that provides banking organizations an option to delay the estimated CECL impact on regulatory capital for an additional two years for a total transition period of up to five years to provide regulatory relief to banking organizations to better focus on supporting lending to creditworthy households and businesses in light of recent strains on the U.S. economy as a result of the COVID-19 pandemic. As a result, entities have the option to gradually phase in the full effect of CECL on regulatory capital over a five-year transition period. The Company implemented its CECL model commencing January 1, 2020 and elected to phase in the full effect of CECL on regulatory capital over the five-year transition period. The following table illustrates the impact of the adoption of the CECL model under ASC 326 on the Company’s consolidated statements of financial position as of January 1, 2020: January 1, 2020 Pre-CECL Adoption Impact of CECL Adoption As Reported Under CECL (Dollars in thousands) Assets: Allowance for credit losses on debt securities: Held-to-maturity $ — $ — $ — Available-for-sale — — — Allowance for credit losses on loans: Investor loans secured by real estate 9,027 16,072 25,099 Business loans secured by real estate 5,492 27,572 33,064 Commercial loans 20,118 9,519 29,637 Retail loans 1,061 2,523 3,584 Deferred tax (liabilities) assets (1,371 ) 18,346 16,975 Liabilities: Allowance for credit losses on off-balance sheet credit exposures $ 3,279 $ 8,285 $ 11,564 Stockholders' equity: Retained earnings $ 396,051 $ (45,625 ) $ 350,426 In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848)—Facilitation of the Effects of Reference Rate Reform on Financial Reporting . In response to concerns about structural risks of interbank offered rates (“IBORs”), and, particularly, the risk of cessation of the London Interbank Offered Rate (“LIBOR”), regulators around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. The amendments in this Update provide optional guidance for a limited time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting as well as optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments in this Update apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. The amendments in this Update are elective and became effective upon issuance for all entities. An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 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. Once elected for a Topic or an Industry Subtopic, the amendments in this Update must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. An entity may elect to apply the amendments in this Update to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. If an entity elects to apply any of the amendments for an eligible hedging relationship existing as of the beginning of the interim period that includes March 12, 2020, any adjustments as a result of those elections must be reflected as of the beginning of that interim period and recognized in accordance with the guidance in Reference Rate Reform Subtopics 848-30, 848-40 and 848-50 (as applicable). If an entity elects to apply any of the amendments for a new hedging relationship entered into between the beginning of the interim period that includes March 12, 2020, any adjustments as a result of those elections must be reflected as of the beginning of the hedging relationship and recognized in accordance with the guidance in Reference Rate Reform Subtopics 848-30, 848-40 and 848-50 (as applicable). The Company does not currently engage in hedging related transactions, and as such, the amendments included in this Update have not had an impact on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement . The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement . The following disclosure requirements for public companies were removed from Topic 820: • The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy • The policy for timing of transfers between levels • The valuation processes for Level 3 fair value measurements The following disclosure requirements for public companies were modified in Topic 820: • The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date The following disclosure requirements for public companies were added to Topic 820: • The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period. • The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this Update became effective for the Company for fiscal years and interim periods within fiscal years beginning on January 1, 2020. This ASU did not have a material effect on the Company’s financial statements. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements. This Update provides clarification on certain aspects of an entity’s implementation of Topic 842 including those that relate to: • Determining the fair value of the underlying asset by lessors that are not manufacturers or dealers. The amendments related to this item carry forward from Topic 840 to Topic 842 an exception that allows lessors who are not manufacturers or dealers to use the cost of the underlying asset as its fair value. • Presentation on the statement of cash flows - sales-type and direct financing leases. The amendments related to this item clarify that all principal payments received on leases by lessors in sales-type or direct financing lease transactions should be reflected in investing activities for entities such as depository and lending institutions within in the scope of Topic 942. • Transition disclosures related to Topic 250, Accounting Changes and Error Corrections. The amendments related to this item clarify the FASB’s original intent by explicitly providing an exception to the paragraph 250-10-50-3 interim disclosure requirements in the Topic 842 transition disclosure requirements, which would otherwise require interim disclosures after the date of adoption of Topic 842 related to the impacts of the change on: (a) income from continuing operations, (b) net income, (c) any other financial statement line item and (d) any affected per-share amounts. The amendments in this Update became effective for the Company for fiscal years and interim periods within fiscal years beginning on January 1, 2020. This ASU did not have a material effect on the Company’s financial statements. Recent Accounting Guidance Not Yet Effective In January 2020, the FASB issued ASU 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323 and Topic 815.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Our accounting policies are described in Note 1. Description of Business and Summary of Significant Accounting Policies , of our audited consolidated financial statements included in our 2019 Form 10-K. Select policies have been reiterated below that have a particular affiliation to our interim financial statements. Revenue Recognition. The Company accounts for certain of its revenue streams in accordance with ASC 606 - Revenue from Contracts with Customers . Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Bank provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies related performance obligations by transferring to the customer a good or service. The recognition of revenue under ASC 606 requires the Company to first identify the contract with the customer, identify the performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and finally recognize revenue when the performance obligations have been satisfied and the good or service has been transferred. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature and can be canceled at any time by the customer or the Bank, such as a deposit account agreement. Other more significant revenue streams for the Company such as interest income on loans and investment securities are specifically excluded from the scope of ASC 606 and are accounted for under other applicable U.S. GAAP. Goodwill and Core Deposit Intangible (“CDI”). Goodwill is generally determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill and intangible assets acquired in a purchase business combination and determined to have an indefinite useful life are not amortized, but tested for impairment at least annually or more frequently if events and circumstances exist that indicate the necessity for such impairment tests to be performed. In general, the Company has selected the fourth quarter as the period to perform the annual impairment test. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Goodwill is the only intangible asset with an indefinite life on our balance sheet. In light of the COVID-19 pandemic and the deterioration of economic conditions as a result, the Company has performed a goodwill impairment assessment, with the assistance from an independent third party, based on the 60-day average market price of the Company’s common stock as of the assessment date, March 31, 2020, and applied a 50% market participant acquisition premium based upon average observed control premiums for regional banks during the 2008 and 2009 financial crisis. Using a 60-day average market price is appropriate to capture the Company’s value as compared to current stock performance impacted by the COVID-19 pandemic and oil markets as well as our pending acquisition of Opus Bank, targeting a June 1, 2020 effective closing date. As of March 31, 2020, our goodwill with a balance of $808.3 million was determined to not be impaired. CDI assets arising from whole bank acquisitions are amortized on either an accelerated basis, reflecting the pattern in which the economic benefits of the intangible assets is consumed or otherwise used up, or on a straight-line amortization method over their estimated useful lives, which range from 6 to 10 years . Leases. The Company accounts for its leases in accordance with ASC 842, which requires the Company to record liabilities for future lease obligations as well as assets representing the right to use the underlying leased asset. Leases with a term of 12 months or less are accounted for using straight-line expense recognition with no liability or asset being recorded for such leases. Other than short-term leases, the Company classifies its leases as either finance leases or operating leases. Leases are classified as finance leases when any of the following are met: (a) the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (b) the lease contains an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (c) the term of the lease represents a major part of the remaining life of the underlying asset, (d) the present value of the future lease payments equals or exceeds substantially all of the fair value of the underlying asset or (e) the underling leased asset is expected to have no alternative use to the lessor at the end of the lease term due to its specialized nature. When the Company’s assessment of a lease does not meet the foregoing criteria, and the term of the lease is in excess of 12 months, the lease is classified as an operating lease. Liabilities to make lease payments and right-of-use assets are determined based on the total contractual base rents for each lease, discounted at the rate implicit in the lease or at the Company’s estimated incremental borrowing rate if the rate is not implicit in the lease. The Company measures future base rents based on the minimum payments specified in the lease agreement, giving consideration for periodic contractual rent increases which are based on an escalation rate or a specified index. When future rent payments are based on an index, the Company uses the index rate observed at the time of lease commencement to measure future lease payments. Liabilities to make lease payments are accounted for using the interest method, which are reduced by periodic rent payments, net of interest accretion. Right-of-use assets for finance leases are amortized on a straight-line basis over the term of the lease, while right-of-use assets for operating leases are amortized over the term of the lease by amounts that represent the difference between periodic straight-line lease expense and periodic interest accretion on the related liability to make lease payments. Expense recognition for finance leases is representative of the sum of periodic amortization of the associated right-of-use asset as well as the periodic interest accretion on the liability to make lease payments. Expense recognition for operating leases is recorded on a straight-line basis. As of March 31, 2020, all of the Company’s leases were classified as either operating leases or short-term leases. From time to time the Company leases portions of the space it leases to other parties through sublease transactions. Income received from these transactions is recorded on a straight-line basis over the term of the sublease. Securities. The Company has established written guidelines and objectives for its investing activities. At the time of purchase, management designates the security as either held to maturity, available-for-sale or held for trading based on the Company’s investment objectives, operational needs and intent. The investments are monitored to ensure that those activities are consistent with the established guidelines and objectives. Securities Held-to-Maturity. Investments in debt securities that management has the positive intent and ability to hold to maturity are reported at cost and adjusted for periodic principal payments and the amortization of premiums and accretion of discounts, which are recognized in interest income using the interest method over the period of time remaining to investment’s maturity. Securities Available-for-Sale. Investments in debt securities that management has no immediate plan to sell, but which may be sold in the future, are carried at fair value. Premiums and discounts are amortized using the interest method over the remaining period to the call date for premiums or contractual maturity for discounts and, in the case of mortgage-backed securities, the estimated average life, which can fluctuate based on the anticipated prepayments on the underlying collateral of the securities. Unrealized holding gains and losses, net of tax, are recorded in a separate component of stockholders’ equity as accumulated other comprehensive income. Realized gains and losses on the sales of securities are determined on the specific identification method, recorded on a trade date basis based on the amortized cost basis of the specific security and are included in noninterest income as net gain (loss) on investment securities. Allowance for Credit Losses on Investment Securities. The ACL on investment securities is determined for both the held-to-maturity and available-for-sale classifications of the investment portfolio in accordance with ASC 326. For available-for-sale investment securities, the Company performs a quarterly qualitative evaluation for securities in an unrealized loss position to determine if, for those investments in an unrealized loss position, the decline in fair value is credit related or non-credit related. In determining whether a security’s decline in fair value is credit related, the Company considers a number of factors including, but not limited to: (i) the extent to which the fair value of the investment is less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) downgrades in credit ratings; (iv) payment structure of the security, (v) the ability of the issuer of the security to make scheduled principal and interest payments and (vi) general market conditions which reflect prospects for the economy as a whole, including interest rates and sector credit spreads. If it is determined that the unrealized loss can be attributed to credit loss, the Company records the amount of credit loss through a charge to provision for credit losses in current period earnings. However, the amount of credit loss recorded in current period earnings is limited to the amount of the total unrealized loss on the security, which is measured as the amount by which the security’s fair value is below its amortized cost. If it is likely the Company will be required to sell the security in an unrealized loss position, the total amount of the loss is recognized in current period earnings. Unrealized losses deemed non-credit related, the Company records the loss, net of tax, through accumulated other comprehensive income. The Company determines expected credit losses on available-for-sale and held-to-maturity securities through a discounted cash flow approach, using the security’s effective interest rate. However, as previously mentioned, the measurement of credit losses on available-for-sale securities only occurs when, through the Company’s qualitative assessment, it is determined all or a portion of the unrealized loss is deemed to be credit related. The Company’s discounted cash flow approach incorporates assumptions about the collectability of future cash flows. The amount of credit loss is measured as the amount by which the security’s amortized cost exceeds the present value of expected future cash flows. Credit losses on available-for-sale securities are measured on an individual basis, while credit losses on held-to-maturity securities are measured on a collective basis according to shared risk characteristics. Credit losses on held-to-maturity securities are only recognized at the individual security level when the Company determines a security no longer possesses risk characteristics similar to others in the portfolio. The Company does not measure credit losses on an investment’s accrued interest receivable, but rather promptly reverses from current period earnings the amount of accrued interest that is no longer deemed collectable. Accrued interest receivable for investment securities is included in accrued interest receivable balances in the consolidated statements of financial condition. Loans Held for Investment. Loans held for investment are loans the Company has the ability and intent to hold until their maturity. These loans are carried at amortized cost, including discounts and premiums on purchased and acquired loans, and net deferred loan origination fees and costs. Purchase discounts and premiums and net deferred loan origination fees and costs on loans are accreted or amortized as an adjustment of yield, using the interest method, over the expected lives of the loans. Income recognition of deferred loan fees and costs is discontinued for loans placed on nonaccrual. Any remaining discounts, premiums, deferred fees or costs and prepayment fees associated with loans that payoff prior to contractual maturity are included in loan interest income in the period of payoff. Loan commitment fees received to originate or purchase a loan are deferred and, if the commitment is exercised, recognized over the life of the loan using the interest method as an adjustment of yield or, if the commitment expires unexercised, recognized as income upon expiration of the commitment. The Company accrues interest on loans using the interest method and only if deemed collectible. Loans for which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is discontinued when principal or interest is past due 90 days based on contractual terms of the loan or when, in the opinion of management, there is reasonable doubt as to collection of principal and or interest. When loans are placed on nonaccrual status, all interest previously accrued but not collected is promptly reversed against current period interest income, and as such an ACL for accrued interest receivable is not established. Interest income generally is not recognized on nonaccrual loans unless the likelihood of further loss is remote. Interest payments received on nonaccrual loans are applied as a reduction to the loan principal balance. Interest accruals are resumed on such loans only when they are brought current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to all principal and interest. Allowance for Credit Losses on Loans. The Company accounts for credit losses on loans in accordance with ASC 326, which requires the Company to record an estimate of expected lifetime credit losses for loans at the time of origination or acquisition. The ACL is maintained at a level deemed appropriate by management to provide for expected credit losses in the portfolio as of the date of the consolidated statements of financial condition. Estimating expected credit losses requires management to use relevant forward-looking information, including the use of reasonable and supportable forecasts. The measurement of the ACL is performed by collectively evaluating loans with similar risk characteristics. The Company measures the ACL on commercial real estate loans and commercial loans using a discounted cash flow approach, and a historical loss rate methodology is used to determine the ACL on retail loans. The Company’s discounted cash flow methodology incorporates a probability of default and loss given default model, as well as expectations of future economic conditions, using reasonable and supportable forecasts. Together, the probability of default and loss given default model with the use of reasonable and supportable forecasts generate estimates for cash flows expected to be collected over the estimated life of a loan. Estimates of future expected cash flows ultimately reflect assumptions made concerning net credit losses over the life of a loan. The use of reasonable and supportable forecasts requires significant judgment, such as selecting forecast scenarios and related scenario-weighting, as well as determining the appropriate length of the forecast horizon. Management leverages economic projections from a reputable and independent third party to inform and provide its reasonable and supportable economic forecasts. Other internal and external indicators of economic forecasts may also be considered by management when developing the forecast metrics. The Company’s ACL model reverts to long-term average loss rates for purposes of estimating expected cash flows beyond a period deemed reasonable and supportable. The Company forecasts economic conditions and expected credit losses over a two-year time horizon before reverting to long-term average loss rates. The duration of the forecast horizon, the period over which forecasts revert to long-term averages, the economic forecasts that management utilizes, as well as additional internal and external indicators of economic forecasts that management considers, may change over time depending on the nature and composition of our loan portfolio. Changes in economic forecasts, in conjunction with changes in loan specific attributes, impact a loan’s probability of default and loss given default, which can drive changes in the determination of the ACL. Expectations of future cash flows are discounted at the loan’s effective interest rate. The resulting ACL represents the amount by which the loan’s amortized cost exceeds the net present value of a loan’s discounted cash flows. The ACL is recorded through a charge to provision for credit losses and is reduced by charge-offs, net of recoveries on loans previously charged-off. It is the Company’s policy to charge-off loan balances at the time they have been deemed uncollectable. Please also see Note 7 - Allowance for Credit Losses , of these consolidated financial statements for additional discussion concerning the Company’s ACL methodology. The Company’s ACL model also includes adjustments for qualitative factors, where appropriate. Since historical information (such as historical net losses and economic cycles) may not always, by themselves, provide a sufficient basis for determining future expected credit losses; the Company periodically considers the need for qualitative adjustments to the ACL. Qualitative adjustments may be related to and include, but not limited to factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios and changes in portfolio segmentation and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. The Company has a credit portfolio review process designed to detect problem loans. Problem loans are typically those of a substandard or worse internal risk grade, and may consist of loans on nonaccrual status, troubled debt restructurings (“TDRs”), loans where the likelihood of foreclosure on underlying collateral has increased, collateral dependent loans and other loans where concern or doubt over the ultimate collectability of all contractual amounts due has become elevated. Such loans may, in the opinion of management, be deemed to no longer possess risk characteristics similar to other loans in the loan portfolio, and as such may require individual evaluation to determine an appropriate ACL for the loan. When a loan is individually evaluated, the Company typically measures the expected credit loss for the loan based on a discounted cash flow approach, unless the loan has been deemed collateral dependent. Collateral dependent loans are loans where the repayment of the loan is expected to come from the operation of and/or eventual liquidation of the underlying collateral. The ACL for collateral dependent loans is determined using estimates for the fair value of the underlying collateral, less costs to sell. Although management uses the best information available to derive estimates necessary to measure an appropriate level of ACL, future adjustments to the ACL may be necessary due to economic, operating, regulatory and other conditions that may extend beyond the Company’s control. Various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL and credit review process. Such agencies may require the Company to recognize additions to the allowance based on judgments different from those of management. The Company has segmented the loan portfolio according to loans that share similar attributes and risk characteristics. Each segment possesses varying degrees of risk based on, among other things, the type of loan, the type of collateral and the sensitivity of the borrower or industry to changes in external factors such as economic conditions. These segment groupings are: investor real estate secured loans, business real estate secured loans, commercial loans and retail loans. Within each segment grouping there are various classes of loans as disclosed below. The Company determines the ACL for loans based on this more detailed loan segmentation and classification. At March 31, 2020 the Company had the following detailed segmentation on classes of loans: Investor Loans Secured by Real Estate: • Commercial real estate non-owner-occupied - Commercial real estate (“CRE”) non-owner-occupied includes loans for which the Company holds real property as collateral, but where the borrower does not occupy the underlying property. The primary risks associated with these loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral, significant increases in interest rates, which may make the real e state loan unprofitable to the borrower, changes in market rents and vacancy of the underlying property. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. • Multifamily - Multifamily loans are secured by multi-tenants (5 or more units) residential real properties. Payments on multifamily loans are dependent on the successful operation or management of the properties, and repayment of these loans may be subject to adverse conditions in the real estate market or the economy. • Construction and land - We originate loans for the construction of one-to-four family and multi-family residences and CRE properties in our primary market area. We concentrate our efforts on single homes and small infill projects in established neighborhoods where there is not abundant land available for development. Construction loans are considered to have higher risks due to construction completion and timing risk, and the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. We occasionally originate land loans located predominantly in California for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s inability to pay and the inability of the Company to recover its investment due to a decline in the fair value of the underlying collateral. Business Loans Secured by Real Estate: • Commercial real estate owner-occupied - CRE owner-occupied includes loans for which the Company holds real property as collateral and where the underlying property is occupied by the borrower, such as with a place of business. These loans are primarily underwritten based on the cash flows of the business and secondarily on the real estate. The primary risks associated with CRE owner-occupied loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make the real estate loan unprofitable to the borrower. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. • Franchise secured by real estate - Franchise real estate secured loans are business loans secured by real property occupied by franchised restaurants, generally quick-service restaurants . These loans are primarily underwritten based on the cash flows of the business and secondarily on the real estate. • Small Business Administration (“SBA”) - We are approved to originate loans under the SBA’s Preferred Lenders Program (“PLP”). The PLP lending status affords us a higher level of delegated credit autonomy, translating to a significantly shorter turnaround time from application to funding, which is critical to our marketing efforts. We originate loans nationwide under the SBA’s 7(a), SBA Express, International Trade and 504(a) loan programs, in conformity with SBA underwriting and documentation standards. SBA loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85% of the loan amount for loans up to $150,000 and 75% of the loan amount for loans of more than $150,000. The Company originates SBA loans with the intent to sell the guaranteed portion into the secondary market on a quarterly basis. Certain loans classified as SBA are secured by commercial real estate property. SBA loans secured by hotels are included in the segment investor loans secured by real estate, and SBA loans secured by all other forms of real estate are included in the business loans secured by real estate segment. All other SBA loans are included in the commercial loans segment below, and are secured by business assets. Commercial Loans: • Commercial and industrial (including franchise commercial loans) (“C&I”) - Loans secured by business assets including inventory, receivables and machinery and equipment to businesses located generally in our primary market area. Loan types includes revolving lines or credit, term loans, seasonal loans and loans secured by liquid collateral such as cash deposits or marketable securities. Franchise credit facilities not secured by real estate and Home Owners’ Association (“HOA”) credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctua te as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers. Retail Loans: • One-to-four family - Although we do not originate, we have acquired first lien single family loans through bank acquisitions. The primary risks of one-to-four family loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make loans unprofitable to the borrower. • Consumer loans - In addition to consumer loans acquired through our various bank acquisitions, we originate a limited number of consumer loans, generally for banking clients only, which consist primarily of home equity lines of credit, savings account secured loans and auto loans. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral. Troubled Debt Restructurings (“TDRs”). From time-to-time, the Company makes modifications to certain loans when a borrower is experiencing financial difficulty. These modifications are made to alleviate temporary impairments in the borrower’s financial condition and/or constraints on the borrower’s ability to repay the loan, and to minimize potential losses to the Company. Modifications typically include: changes in the amortization terms of the loan, reductions in interest rates, acceptance of interest only payments and, in limited cases, concessions to the outstanding loan balance. Such loans are typically placed on nonaccrual status and are returned to accrual status when all contractual amounts past due have been brought current, the loan has performed under the modified terms of the loan agreement for a period of at least six months and the ultimate collectability of all contractual amounts due under the modified terms of the loan agreement is no longer in doubt. The Company typically measures the ACL for TDRs on an individual basis when the loans are deemed to no longer share similar risk characteristics with other loans in the portfolio. The determination of the ACL for TDRs is based on a discounted cash flow approach for both those measured collectively and individually, unless the loan is deemed collateral dependent, which requires measurement of the ACL based on the fair value of the collateral less cost to sell. Acquired Loans. Loans acquired through a purchase or a business combination are recorded at their fair value at the acquisition date. The Company performs an assessment of acquired loans to first determine if such loans have experienced more than insignificant deterioration in credit quality since their origination and thus should be classified and accounted for as purchased credit deteriorated (“PCD”) loans. For loans that have not experienced more than insignificant deterioration in credit quality since origination, referred to as non-PCD loans, the Company records such loans at fair value, with any resulting discount or premium accreted or amortized into interest income over the remaining life of the loan using the interest method. Additionally, upon the purchase or acquisition of non-PCD loans, the Company measures and records an ACL based on the Company’s methodology for determining the ACL. The ACL for non-PCD loans is recorded through a charge to the provision for credit losses in the period in which the loans were purchased or acquired. Acquired loans that are classified as PCD are acquired at fair value, which includes any resulting premiums or discounts. Premiums and discounts are amortized or accreted into interest income over the remaining life of the loan using the interest method. Unlike non-PCD loans, the initial ACL for PCD loans is established through an adjustment to the acquired loan balance and not through a charge to the provision for credit losses in the period in which the loans were acquired. The ACL for PCD loans is determined with the use of the Company’s ACL methodology. Characteristics of PCD loans include: delinquency, downgrade in credit quality since origination, loans on nonaccrual status and/or other factors the Company may become aware of through its initial analysis of acquired loans that may indicate there has been more than insignificant deterioration in credit quality since a loan’s origination. As of January 1, 2020 and March 31, 2020, there were no loans classified as PCD loans. Subsequent to acquisition, the ACL for both non-PCD and PCD loans are determined with the use of the Company’s ACL methodology in the same manner as all other loans. Other Real Estate Owned (“OREO”). Real estate properties acquired through, or in lieu of, loan foreclosure are recorded at fair value, less cost to sell, with any excess of the loan’s amortized cost balance over the fair value of the property recorded as a charge against the ACL. The Company obtains an appraisal and/or market valuation on all other real estate owned at the time of possession. After foreclosure, valuations are periodically performed by management. Any subsequent declines in fair value are recorded as a charge to non-interest expense in current period earnings with a corresponding write-down to the asset. All legal fees and direct costs, including foreclosure and other related c

At March 31, 2020 , the Company had accumulated other comprehensive income of $62.2 million , or $44.4 million net of tax, compared to an accumulated other comprehensive income of $30.1 million , or $21.5 million net of tax, at December 31, 2019 . At March 31, 2020 and December 31, 2019 , there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity. The Company reviews individual securities classified as available-for-sale to determine whether a decline in fair value below the amortized cost basis is deemed credit related or due to other factors such as changes in interest rates and general market conditions. The Company recognizes credit losses in current period earnings when declines in the fair value of individual available-for-sale securities are below their amortized cost, and the decline in fair value is deemed to be credit related. Declines in fair value below amortized cost not deemed credit related are recorded net of tax in accumulated other comprehensive income. In the event the Company is required to sell or has the intent to sell an available-for-sale security that has experienced a decline in fair value below its amortized cost, the Company writes the amortized cost of the security down to fair value in the current period. As of March 31, 2020 , the Company has not recorded credit losses on certain available-for-sale securities that were in an unrealized loss position due to the high quality of the investments, with investment grade ratings, and many of them are issued by U.S. government agencies. Additionally, the Company continues to receive contractual principal and interest payments in a timely manner. The Company performed an assessment of these investments as of March 31, 2020, and does not believe the declines in fair value are credit related. At March 31, 2020 , there were no available-for-sale or held-to-maturity securities in nonaccrual status. All securities in the portfolio were current with their contractual principal and interest payments. At March 31, 2020 and December 31, 2019 , there were no securities purchased with deterioration in credit quality since their origination. At March 31, 2020 , there were no collateral dependent available-for-sale or held-to-maturity securities.

During the three months ended March 31, 2020 , December 31, 2019 and March 31, 2019 , the Company recognized gross losses on sales of available-for-sale securities in the amount of $204,000 , $147,000 and $615,000 , respectively. The Company had net proceeds from the sales of available-for-sale securities of $155.3 million during the three months ended March 31, 2020 , of which $57.4 million were receivables for securities with a later settlement date . The Company had net proceeds from the sales of available-for-sale securities of $133.3 million and $168.8 million during the three months ended December 31, 2019 and March 31, 2019 . Investment securities with carrying values of $111.5 million and $125.7 million as of March 31, 2020 and December 31, 2019 , respectively, were pledged to secure public deposits, other borrowings and for other purposes as required or permitted by law. FHLB, FRB and Other Stock At March 31, 2020 , the Company had $17.3 million in Federal Home Loan Bank of San Francisco (“FHLB”) stock, $51.7 million in Federal Reserve Bank of San Francisco (“FRB”) stock and $23.9 million in other stock, all carried at cost. During the three months ended March 31, 2020 and March 31, 2019 , the FHLB repurchased $10.3 million and $12.9 million , respectively, of the Company’s excess FHLB stock through its stock repurchase program. During the three months ended December 31, 2019 , the FHLB did no t repurchase any of the Company’s excess FHLB stock through its stock repurchase program. The Company evaluates its investments in FHLB, FRB and other stock for impairment periodically, including their capital adequacy and overall financial condition. No impairment loss has been recorded through March 31, 2020 . Allowance for Credit Losses on Investment Securities The Company accounts for credit losses on debt securities in accordance with ASC 326, which requires the Company to record an ACL on held-to-maturity investment securities at the time of purchase or acquisition. The ACL for held-to-maturity investment securities represents the Company’s current estimate of expected credit losses that may be incurred over the life of the investment. An ACL on available-for-sale investment securities is recorded when the fair value of the investment is below its amortized cost and the decline in fair value has been deemed to be credit related through the Company’s qualitative assessment. Non-credit related declines in fair value of available-for-sale investment securities are not recorded through an ACL, but rather recorded as an adjustment to accumulated other comprehensive income, net of tax. The Company determines credit losses on both available-for-sale investment securities through the use of a discounted cash flow approach using the security’s effective interest rate. The ACL is measured as the amount by which an investment security’s amortized cost exceeds the net present value of expected future cash flows. However, the amount of credit losses for available-for-sale investment securities is limited to the amount of a security’s unrealized loss. The ACL is established through a charge to provision for credit losses in current period earnings. The Company did not record an ACL for available-for-sale or held-to-maturity investment securities during the three months ended March 31, 2020 . For available-for-sale securities where estimated fair value was below amortized cost, such declines were deemed non-credit related and recorded as an adjustment to accumulated other comprehensive income, net of tax. Non-credit related decline in fair value of available-for-sale investment securities can be attributed to changes in interest rates and other market related factors. The Company did not record an ACL for held-to maturity securities during the three months ended March 31, 2020 , because the likelihood of non-repayment is remote.

(2) Loans to businesses that are collateralized by real estate where the operating cash flow of the business is the primary source of repayment. (3) SBA loans that are collateralized by real property other than hotel/motel real property. (4) Loans to businesses where the operating cash flow of the business is the primary source of repayment. (5) Single family residential includes home equity lines of credit, as well as second trust deeds. (6) Includes unaccreted fair value net purchase discounts of $35.9 million and $40.7 million as of March 31, 2020 and December 31, 2019 , respectively. (7) The ACL as of December 31, 2019 was the allowance for loan and lease losses (“ALLL”) accounted for under ASC 450 and ASC 310, which is reflective of probable incurred losses as of the balance sheet date. The ACL at March 31, 2020 is accounted for under ASC 326, which is reflective of estimated expected lifetime credit losses. Loans Serviced for Others The Company generally retains the servicing rights of the guaranteed portion of SBA loans sold, for which the Company records a servicing asset at fair value within its other assets category. At March 31, 2020 and December 31, 2019 , the servicing asset totaled $7.3 million and $7.7 million , respectively, and was included in other assets in the Company’s consolidated balance sheets. Servicing rights are evaluated for impairment based upon the fair value of the rights as compared to the carrying amount. Impairment is recognized through a valuation allowance, to the extent the fair value is less than the carrying amount. At March 31, 2020 and December 31, 2019 , the Company determined that no valuation allowance was necessary. Loans serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balance of loans and participations serviced for others were $614.7 million at March 31, 2020 and $633.8 million at December 31, 2019 , including SBA participations serviced for others totaling $455.9 million at March 31, 2020 and $475.3 million at December 31, 2019 . Concentration of Credit Risk As of March 31, 2020 , the Company’s loan portfolio was primarily collateralized by various forms of real estate and business assets located predominately in California. The Company’s loan portfolio contains concentrations of credit in multifamily real estate, commercial non-owner-occupied real estate, commercial owner-occupied real estate loans and commercial and industrial business loans. The Bank maintains policies approved by the Bank’s Board of Directors (the “Bank Board”) that address these concentrations and diversifies its loan portfolio through loan originations, purchases and sales to meet approved concentration levels. While management believes that the collateral presently securing these loans is adequate, there can be no assurances that a significant deterioration in the California real estate market or economy would not expose the Company to significantly greater credit risk. Under applicable laws and regulations, the Bank may not make secured loans to one borrower in excess of 25% of the Bank’s unimpaired capital plus surplus and likewise in excess of 15% of the Bank’s unimpaired capital plus surplus for unsecured loans. These loans-to-one borrower limitations result in a dollar limitation of $581.5 million for secured loans and $348.9 million for unsecured loans at March 31, 2020 . In order to manage concentration risk, the Bank maintains a house lending limit well below these statutory maximums. At March 31, 2020 , the Bank’s largest aggregate outstanding balance of loans to one borrower was $128.4 million comprised of $101.5 million and $26.9 million of secured CRE non-owner-occupied and unsecured C&I credit, respectively. Credit Quality and Credit Risk Management The Company’s credit quality and credit risk are controlled in two distinct areas. The first is the loan origination process, wherein the Bank underwrites credit quality and chooses which risks it is willing to accept. The Company maintains a comprehensive credit policy, which sets forth maximum tolerances for key elements of loan risk. The policy identifies and sets forth specific guidelines for analyzing each of the loan products the Company offers from both an individual and portfolio-wide basis. The credit policy is reviewed annually by the Bank Board. The Bank’s underwriters ensure key risk factors are analyzed with nearly all underwriting including a comprehensive global cash flow analysis of the prospective borrowers. The second is in the ongoing oversight of the loan portfolio, where existing credit risk is measured and monitored, and where performance issues are dealt with in a timely and comprehensive fashion. Credit risk is managed within the loan portfolio by the Company’s portfolio managers based on a comprehensive credit and portfolio review policy. This policy requires a program of financial data collection and analysis, comprehensive loan reviews, property and/or business inspections and monitoring of portfolio concentrations and trends. The portfolio managers also monitor borrowing bases under asset-based lines of credit, loan covenants and other conditions associated with the Company’s business loans as a means to help identify potential credit risk. Individual loans, excluding the homogeneous loan portfolio, are reviewed at least every two years and in most cases, more often, including the assignment or confirmation of a risk grade. Risk grades are based on a six -grade Pass scale, along with Special Mention, Substandard, Doubtful and Loss classifications, as such classifications are defined by the regulatory agencies. The assignment of risk grades allows the Company to, among other things, identify the risk associated with each credit in the portfolio, and to provide a basis for estimating credit losses inherent in the portfolio. Risk grades are reviewed regularly with the Company’s Credit and Portfolio Review Committee, and the portfolio management and risk grading process is reviewed on an ongoing basis by an independent loan review function, as well as by regulatory agencies during scheduled examinations. The following provides brief definitions for risk grades assigned to loans in the portfolio: • Pass classifications represent assets with a level of credit quality, in which no well-defined deficiency or weakness exists. • Special Mention assets do not currently expose the Bank to a sufficient risk to warrant classification in one of the adverse categories, but possess correctable deficiencies or potential weaknesses deserving management’s close attention. • Substandard assets are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. These assets are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. OREO acquired from foreclosure is also classified as Substandard. • Doubtful credits have all the weaknesses inherent in Substandard credits, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. • Loss assets are those that are considered uncollectible and of such little value that their continuance as assets is not warranted. Amounts classified as loss are promptly charged off. The Bank’s portfolio managers also manage loan performance risks, collections, workouts, bankruptcies and foreclosures. A special department, whose portfolio managers have professional expertise in these areas, typically handles or advises on these types of matters. Loan performance risks are mitigated by our portfolio managers acting promptly and assertively to address problem credits when they are identified. Collection efforts commence immediately upon non-payment, and the portfolio managers seek to promptly determine the appropriate steps to minimize the Company’s risk of loss. When foreclosure will maximize the Company’s recovery for a non-performing loan, the portfolio managers will take appropriate action to initiate the foreclosure process. When a loan is graded as special mention, substandard or doubtful, the Company obtains an updated valuation of the underlying collateral. If, through the Company’s credit risk management process, it is determined the ultimate repayment of a loan will come from the foreclosure upon and ultimate sale of the underlying collateral, the loan is deemed collateral dependent and evaluated individually to determine an appropriate ACL for the loan. The ACL for such loans is measured as the amount by which the fair value of the underlying collateral, less estimated costs to sell, is less than the amortized cost of the loan. The Company typically continues to obtain or confirm updated valuations of underlying collateral for special mention and classified loans on an annual or biannual basis in order to have the most current indication of fair value of the underlying collateral securing the loan. Additionally, once a loan is identified as collateral dependent, due to the likelihood of foreclosure, and repayment of the loan is expected to come from the eventual sale of the underlying collateral, an analysis of the underlying collateral is performed at least quarterly. Changes in the estimated fair value of the collateral are reflected in the lifetime ACL for the loan. Balances deemed to be uncollectable are promptly charged-off.

Individually Evaluated Loans Beginning on January 1, 2020, the Company evaluates loans collectively for purposes of determining the ACL in accordance with ASC 326. Collective evaluation is based on aggregating loans deemed to possess similar risk characteristics. In certain instances the Company may identify loans that it believes no longer possess risk characteristics similar to other loans in the portfolio. These loans are typically identified from a substandard or worse internal risk grade, since the specific attributes and risks associated with such loans tend to become unique as the credit deteriorates. Such loans are typically nonperforming, modified through a TDR and/or are deemed collateral dependent, where the ultimate repayment of the loan is expected to come from the operation of or eventual sale of the collateral. Loans that are deemed by management to no longer possess risk characteristics similar to other loans in the portfolio are evaluated individually for purposes of determining an appropriate lifetime ACL. The Company uses a discounted cash flow approach, using the loan’s effective interest rate, for determining the ACL on individually evaluated loans, unless the loan is deemed collateral dependent, which requires evaluation based on the estimated fair value of the underlying collateral, less estimated costs to sell. The Company may increase or decrease the ACL for collateral dependent individually evaluated loans based on changes in the estimated fair value of the collateral. Changes in the ACL for all other individually evaluated loans is based substantially on the Company’s evaluation of cash flows expected to be received from such loans. As of March 31, 2020, $22.3 million of loans were individually evaluated, and the ACL attributable to such loans was $1.9 million . At March 31, 2020, $16.3 million of individually evaluated loans were evaluated using a discounted cash flow approach and $6.0 million of individually evaluated loans were evaluated based on the underlying value of the collateral. The Company had individually evaluated loans on nonaccrual status of $20.6 million at March 31, 2020 . Impaired Loans Prior to the adoption of ASC 326 on January 1, 2020, the Company classified loans as impaired when, based on current information and events, it was probable that the Company would be unable to collect all amounts due according to the contractual terms of the loan agreement or it was determined that the likelihood of the Company receiving all scheduled payments, including interest, when due was remote. Credit losses on impaired loans were determined separately based on the guidance in ASC 310. Beginning January 1, 2020, the Company accounts for credit losses on all loans in accordance with ASC 326, which eliminates the concept of an impaired loan within the context of determining credit losses, and requires all loans to be evaluated for credit losses collectively. Loans are only evaluated individually when they are deemed to no longer possess similar risk characteristics with other loans within the portfolio. Prior to the adoption of ASC 326, the Company reviewed loans for impairment when the loan was classified as substandard or worse, delinquent 90 days, determined by management to be collateral dependent, when the borrower files bankruptcy or is granted a loan modification in a TDR. Measurement of impairment was based on the loan’s expected future cash flows discounted at the loan’s effective interest rate, measured by reference to an observable market value, if one existed, or the fair value of the collateral if the loan was deemed collateral dependent. Valuation allowances were determined on a loan-by-loan basis or by aggregating loans with similar risk characteristics. Charge-offs were recorded when amounts were no longer deemed collectable.

The Company had impaired loans on nonaccrual status of $8.5 million at December 31, 2019 . The Company had no loans 90 days or more past due and still accruing at December 31, 2019 . Troubled Debt Restructurings We sometimes modify or restructure loans when the borrower is experiencing financial difficulties by making a concession to the borrower in the form of changes in the amortization terms, reductions in the interest rates, the acceptance of interest only payments and, in limited cases, concessions to the outstanding loan balances. These loans are classified as TDR. TDRs are loans modified for the purpose of alleviating temporary impairments to the borrower’s financial condition or cash flows. A workout plan between us and the borrower is designed to provide a bridge for borrower cash flow shortfalls in the near term. A TDR loan may be returned to accrual status when the loan is brought current, has performed in accordance with the contractual restructured terms for a time frame of at least six months, and the ultimate collectability of the total contractual restructured principal and interest in no longer in doubt. At March 31, 2020 and December 31, 2019 , the amortized cost of TDRs totaled $2.3 million and $3.0 million , respectively. TDRs consisted of two loans at March 31, 2020, the same loans reported as TDRs at December 31, 2019. Modifications consisted of terms being modified to extend the maturity date for 24 months or less. One of these TDRs became nonaccrual at March 31, 2020 but both loans were current and on accrual status as of December 31, 2019 . The modification of these loans did not have an impact on their amortized cost. Purchased Credit Deteriorated and Purchased Credit Impaired Loans Prior to the adoption of ASC 326, the Company accounted for purchased credit impaired loans (“PCI loans”) and income recognition thereof in accordance with ASC Subtopic 310-30 Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality. PCI loans are loans that as of the date of their acquisition have experienced deterioration in credit quality between origination and acquisition and for which it was probable, at acquisition, that not all contractually required payments would be collected. Following the adoption of ASC 326 on January 1, 2020, the Company analyzes acquired loans for more-than-insignificant deterioration in credit quality since their origination. Such loans are classified as purchased credit deteriorated loans. Please also see Note 3 - Significant Accounting Policies, of these financial statements for more information concerning the accounting for PCD loans. As of March 31, 2020 there were no PCD loans. As of December 31, 2019, there were $1.2 million of PCI loans, of which none were placed on nonaccrual status. Prior to the adoption of ASC 326, the Company measured the amount by which the undiscounted expected cash future flows on PCI loans exceed the estimated fair value of the loan on the date of acquisition as the “accretable yield,” representing the amount of estimated future interest income on the loan. The amount of accretable yield was re-measured at each financial reporting date, representing the difference between the remaining undiscounted expected cash flows and the current carrying value of the PCI loan. Following the adoption of ASC 326, the Company accounts for interest income on PCD loans using the interest method, whereby any purchase discounts are accreted into interest income as an adjustment of the loan’s yield. An accretable yield is not determined for PCD loans. Nonaccrual Loans When loans are placed on nonaccrual status, previously accrued but unpaid interest is promptly reversed from earnings. Payments received on nonaccrual loans are generally applied as a reduction to the loan principal balance. If the likelihood of further loss is remote, the Company will recognize interest on a cash basis only. Loans may be returned to accruing status if the Company believes that all remaining principal and interest is fully collectible and there has been at least three months of sustained repayment performance since the loan was placed on nonaccrual. The Company typically does not accrue interest on loans 90 days or more past due or when, in the opinion of management, there is reasonable doubt as to the timely collection of principal or interest. However, when such loans are well secured and in the process of collection, the Company may continue with the accrual of interest.

Provision for Loan and Lease Losses [Abstract]
Allowance for Loan Losses	Allowance for Credit Losses The Company accounts for credit losses on loans in accordance with ASC 326 - Financial Instruments - Credit Losses , to determine the ACL. ASC 326 requires the Company to recognize estimates for lifetime losses on loans and unfunded loan commitments at the time of origination or acquisition. The recognition of losses at origination or acquisition represents the Company’s best estimate of the lifetime expected credit loss associated with a loan given the facts and circumstances associated with the particular loan, and involves the use of significant management judgement and estimates. The Company uses a discounted cash flow model when determining estimates for the ACL for commercial real estate loans and commercial loans, which are the majority of the loan portfolio, and uses a historical loss rate model for retail loans. The Company also utilizes proxy loan data in its ACL model where the Company’s own historical data is not available. The discounted cash flow model is applied on an instrument-by-instrument basis, and for loans with similar risk characteristics, to derive estimates for the lifetime ACL for each loan. The discounted cash flow methodology relies on several significant components essential to the development of estimates for future cash flows on loans and unfunded commitments. These components consist of: (i) the estimated probability of default, (ii) the estimated loss given default, which represents the estimated severity of the loss when a loan is in default, (iii) estimates for prepayment activity on loans and (iv) the estimated exposure to the Company at default (“EAD”). These components are also heavily influenced by changes economic forecasts employed in the model over a reasonable and supportable period. The Company’s ACL methodology for unfunded loan commitments also includes assumptions concerning the probability the unfunded commitment will be drawn upon by the borrower. These assumptions are based on the Company’s historical experience. The Company’s discounted cash flow ACL model for commercial real estate and commercial loans uses internally derived estimates for prepayments in determining the amount and timing of future contractual cash flows to be collected. The estimate of future cash flows also incorporates estimates for contractual amounts the Company believes may not be collected, which are based on assumptions for PD, LGD and EAD. EAD is the estimated outstanding balance of the loan at the time of default. It is determined by the contractual payment schedule and expected payment profile of the loan, incorporating estimates for expected prepayments and future draws on revolving credit facilities. The Company discounts cash flows using the effective interest rate on the loan. The effective interest rate represents the contractual rate on the loan; adjusted for any purchase premiums, purchase discounts, and deferred fees and costs associated with the origination of the loan. The Company has made an accounting policy election to adjust the effective interest rate to take into consideration the effects of estimated prepayments. The ACL for loans is determined by measuring the amount by which a loan’s amortized cost exceeds its discounted cash flows. Probability of Default The PD for commercial real estate loans is based largely on a model provided by a third party, using proxy loan information. The PDs generated by this model are reflective of current and expected changes in economic conditions and conditions in the commercial real estate market, and how they are expected to impact loan level and property level attributes, and ultimately the likelihood of a default event occurring. Significant loan and property level attributes include: loan to value ratios, debt service coverage, loan size, loan vintage and property types. The PD for commercial loans is based on an internally developed PD rating scale that assigns PDs based on the Company’s internal risk grades for loans. This internally developed PD rating scale is based on a combination of the Company’s own historical data and observed historical data from the Company’s peers, which consist of banks that management believes align with our business profile. As credit risk grades change for loans in the commercial segment, the PD assigned to them also changes. As with commercial real estate loans, the PD for commercial loans is also impacted by current and expected economic conditions. The Company considers loans to be in default when they are 90 days or more past due and still accruing or placed on nonaccrual status. Loss Given Default LGDs for commercial real estate loans are derived from a third party, using proxy loan information, and are based on loan and property level characteristics in the Company’s loan portfolio, such as: loan to values, estimated time to resolution, property size and current and estimated future market price changes for underlying collateral. The LGD is highly dependent upon loan to value ratios, and incorporates estimates for the expense associated with managing the loan through to resolution. LGDs also incorporate an estimate for the loss severity associated with loans where the borrower fails to meet their debt obligation at maturity, such as through a balloon payment or the refinancing of the loan through another lender. External factors that have an impact on LGDs include: changes in the CRE Price Index, GDP growth rate, unemployment rates and the Moody’s Baa rating corporate debt interest rate spread. LGDs are applied to each loan in the commercial real estate portfolio, and in conjunction with the PD, produce estimates for net cash flows not expected to be collected over the estimated term of the loan. LGDs for commercial loans are also derived from a third party that has a considerable database of credit related information specific to the financial services industry and the type of loans within this segment, and is used to generate annual default information for commercial loans. These proxy LGDs are dependent upon data inputs such as: credit quality, borrower industry, region, borrower size and debt seniority. LGDs are then applied to each loan in the commercial portfolio, and in conjunction with the PD, produce estimates for net cash flows not expected to be collected over the estimated term of the loan. Historical Loss Rates for Retail Loans The historical loss rate model for retail loans are derived from a third party that has a considerable database of credit related information for retail loans. Key loan level attributes and economic drivers in determining the loss rate for retail loans include FICO scores, vintage, as well as geography, unemployment rates and changes in consumer real estate prices. Forecasts U.S. GAAP requires the Company to develop reasonable and supportable forecasts of future conditions, and estimate how those forecasts are expected to impact a borrower’s ability to satisfy their obligation to the Bank and the ultimate collectability of future cash flows over the life of the loan. The Company uses economic scenarios from Moody’s Analytics in its estimation of a borrower’s ability to repay a loan in future periods. These scenarios are based on past events, current conditions and the likelihood of future events occurring. These scenarios typically are comprised of: (1) a base-case scenario, (2) an upside scenario, representing slightly better economic conditions than currently experienced and (3) a downside scenario, representing recessionary conditions. Management periodically evaluates economic scenarios and may decide that a particular economic scenario or a combination of probability-weighted economic scenarios should be used in the Company’s ACL model. The economic scenario or scenarios chosen for the model and, to the extent more than one scenario is used, the weights that are assigned to them, are based on the Company’s estimate of the probability of each scenario occurring, which is based in part on analysis performed by an independent third-party. Economic scenarios, as well as assumptions within those scenarios, whether to use more than one scenario and the relative weighting or multiple scenarios, if used, can vary based on changes in current and expected economic conditions and due to the occurrence of specific events such as the COVID-19 pandemic. The Company recognizes the non-linearity of credit losses relative to economic performance and thus the Company believes the consideration and, if appropriate under the circumstances, use of multiple probability-weighted economic scenarios is appropriate in estimating credit losses over the forecast period. The approach of considering and, if appropriate, using multiple probability-weighted scenarios is based on certain assumptions. The first assumption is that no single forecast of the economy, however detailed or complex, is completely accurate over a reasonable forecast time-frame, and is subject to revisions over time. By considering multiple scenario outcomes and, when utilizing multiple scenario outcomes is appropriate under the circumstances, assigning reasonable probability weightings to them, some of the uncertainty associated with a single scenario approach, the Company believes, is mitigated. As of January 1, 2020, upon the adoption of ASC 326, the Company’s ACL model used three probability-weighted scenarios representing a base-case scenario, an upside scenario and a downside scenario. The weightings assigned to each scenario were as follows: the base-case scenario, or most likely scenario, was assigned a weighting of 40%, while the upside and downside scenarios were each assigned weightings of 30%. As of March 31, 2020, and in response to the COVID-19 pandemic, economic forecasts used in the Company’s ACL model incorporate assumptions associated with the estimated economic effects of the pandemic. The Company, with the assistance of an independent third party, determined it appropriate to include an economic scenario that is reflective of the estimated economic effects of the pandemic, including the responses to contain the pandemic. This scenario is referred to as the critical pandemic scenario. Additionally, the Company evaluated the weightings of each economic scenario in the current period with the assistance of an independent third party, and revised those weightings to levels it believes appropriately reflect the likelihood of outcomes for each scenario given the change in the current economic environment. As such, for the three months ended March 31, 2020, The Company’s ACL model incorporated three economic scenarios comprised of: the critical pandemic scenario weighted 30%, the more severe (as compared to the critical pandemic scenario) downside scenario weighted 32.5% and the base-case scenario weighted 37.5%. The weightings of economic scenarios in the current period are reflective of rapidly changing economic conditions, economic uncertainty and volatility in financial markets brought on by the COVID-19 pandemic, and the estimated likelihood that each scenario may occur as of March 31, 2020. The Company currently forecasts economic conditions over a two-year period, which we believe is a reasonable and supportable period. Beyond the point which the Company can provide for a reasonable and supportable forecast, economic variables revert to their long-term averages. The Company has reflected this reversion over a period of three years in each of its economic scenarios used to generate the overall probability-weighted forecast. Changes in economic forecasts impact the PD, LGD and EAD for each loan, and therefore influence the amount of future cash flows for each loan the Company does not expect to collect. The Company derives the economic forecasts it uses in its ACL model from an independent third party that has a large team of economists, data-base managers and operational engineers with a history of producing monthly economic forecasts for over 25 years. The forecasts produced by this third party have been widely used by banks, credit unions, government agencies and real estate developers. These economic forecasts cover all states and metropolitan areas in the Unites States, and reflect changes in economic variables such as: GDP growth, interest rates, employment rates, changes in wages, retail sales, industrial production, metrics associated with the single-family and multifamily housing markets, vacancy rates, changes in equity market prices and energy markets. It is important to note that the Company’s ACL model relies on multiple economic variables, which are used under several economic scenarios. Although no one economic variable can fully demonstrate the sensitivity of the ACL calculation to changes in the economic variables used in the model, the Company has identified certain economic variables that have significant influence in the Company’s model for determining the ACL. As of March 31, 2020, the Company’s ACL model incorporated the following assumptions for key economic variables in the base-case and downside scenarios: Base-case Scenario: • CRE Price Index decreases by approximately 3% in the intermediate term, with a return to growth in the second half of 2020. • A moderate decrease in real GDP of less than 1% in the intermediate term, with a return to modest growth in the second half of 2020. • Moderate quarterly increases in the U.S. unemployment rate to over 4% over the next two years. Critical Pandemic Scenario: • CRE Price Index decreases by approximately 20% in the intermediate term, with continued gradual declines over a period approximately 12 months. • A decrease in real GDP of approximately 5% in the intermediate term, and negative for most of 2020, before returning to a slight level of growth beginning in the fourth quarter of 2020. • Increases in the U.S. unemployment rate to a peak of over 6% within the next 5 quarters. Downside Scenario: • CRE Price Index decreases by approximately 14% in the intermediate term, with continued quarterly declines of approximately 7% to 15% over the next 5 quarters. • A decrease in real GDP of approximately 4% in the intermediate term, and negative through the beginning of 2021. • Increases in the U.S. unemployment rate to a peak of 7.4% within the next 6 quarters, and remaining elevated to slightly decreasing in the remaining quarters within the forecast period. Qualitative Adjustments The Company recognizes that historical information used as the basis for determining future expected credit losses may not always, by themselves, provide a sufficient basis for determining future expected credit losses. The Company, therefore, periodically considers the need for qualitative adjustments to the ACL. Qualitative adjustments may be related to and include, but not be limited to, factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios and changes in portfolio segmentation and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. As of March 31, 2020, qualitative adjustments included in the ACL totaled $6.0 million . These adjustments relate to management’s assessment of the economic forecasts used in the model. Management determined through additional review of economic indicators and forecasts of economic conditions that there is potential for economic conditions under the base-case scenario to worsen. Management observed through this additional review that certain key economic indicators may experience additional declines over the intermediate term. Real GDP may experience a decrease of approximately 18%, the U.S. unemployment rate may reach 9%, and the CRE price index may also experience further weakness. Management concluded the potential for additional weakness in these economic indicators under a base-case scenario may contribute to higher lifetime losses in CRE non-owner-occupied, construction and land and franchise loans as of March 31, 2020. Management reviews the need for and appropriate level of qualitative adjustments on a quarterly basis, and as such, the amount and allocation of qualitative adjustments may change in future periods.

KBRA assigned investment grade ratings of BBB+ and BBB for the Corporation’s senior unsecured debt and subordinated debt, respectively, and a deposit rating of A- for the Bank. The Company’s and Bank’s ratings were reaffirmed in February 2020 by KBRA following the announcement of the proposed acquisition of Opus. As of March 31, 2020 , the Corporation has two unconsolidated Delaware statutory trust subsidiaries, Heritage Oaks Capital Trust II and Santa Lucia Bancorp (CA) Capital Trust. Both are used as business trusts for the purpose of issuing junior subordinated debt to third party investors. The junior subordinated debt was issued in connection with the trust preferred securities offerings. The Corporation is not allowed to consolidate any trust preferred securities into the Company’s consolidated financial statements. The resulting effect on the Company’s consolidated financial statements is to report the subordinated debentures as a component of the Company’s liabilities, and its ownership interest in the trusts as a component of other assets.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share In February 2019, the Company’s Compensation Committee of Board of Directors reviewed the various forms of outstanding equity awards, including restricted stock and restrict stock units (“RSUs”), and approved that unvested restricted stock awards will be considered participating securities. As a result of the different treatment of unvested restricted stock and unvested RSUs, beginning in 2019, earnings per common share is computed using the two-class method. Under the two-class method, distributed and undistributed earnings allocable to participating securities are deducted from net income to determine net income allocable to common shareholders, which is then used in the numerator of both basic and diluted earnings per share calculations. Basic earnings per common share is computed by dividing net income allocable to common shareholders by the weighted average number of common shares outstanding for the reporting period, excluding outstanding participating securities. Diluted earnings per common share is computed by dividing net income allocable to common shareholders by the weighted average number of common shares outstanding over the reporting period, adjusted to include the effect of potentially dilutive common shares, but excludes awards considered participating securities. The computation of diluted earnings per common share excludes the impact of the assumed exercise or issuance of securities that would have an anti-dilutive effect. The following tables set forth the Company’s earnings per share calculations for the periods indicated: Three Months Ended March 31, 2020 December 31, 2019 March 31, 2019 (Dollars in thousands, except per share data) Basic Net income $ 25,740 $ 41,098 $ 38,718 Less: Earnings allocated to participating securities (232 ) (426 ) (347 ) Net income allocated to common stockholders $ 25,508 $ 40,672 $ 38,371 Weighted average common shares outstanding 59,007,191 58,816,352 61,987,605 Basic earnings per common share $ 0.43 $ 0.69 $ 0.62 Diluted Net income allocated to common stockholders $ 25,508 $ 40,672 $ 38,371 Weighted average common shares outstanding 59,007,191 58,816,352 61,987,605 Diluted effect of share-based compensation 182,526 365,702 298,178 Weighted average diluted common shares 59,189,717 59,182,054 62,285,783 Diluted earnings per common share $ 0.43 $ 0.69 $ 0.62 The impact of stock options, which are anti-dilutive, are excluded from the computations of diluted earnings per share. The dilutive impact of these securities could be included in future computations of diluted earnings per share if the market price of the common stock increases. For the three months ended March 31, 2020 , there were no RSUs or stock options that were anti-dilutive.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of an asset or liability is the exchange price that would be received to sell that asset or paid to transfer that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value are discussed below. In accordance with accounting guidance, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, volatilities, etc.) or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market. Level 3 - Valuation is generated from model-based techniques where one or more significant inputs are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models, and similar techniques. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates 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 fair values presented. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following is a description of both the general and specific valuation methodologies used to measure financial assets and liabilities on a recurring basis, as well as the general classification of these instruments pursuant to the fair value hierarchy. Investment securities – Investment securities are generally valued based upon quotes obtained from independent third-party pricing services, which use evaluated pricing applications and model processes. Observable market inputs, such as, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data are considered as part of the evaluation. The inputs are related directly to the security being evaluated, or indirectly to a similarly situated security. Market assumptions and market data are utilized in the valuation models. The Company reviews the market prices provided by the third-party pricing service for reasonableness based on the Company’s understanding of the market place and credit issues related to the securities. The Company has not made any adjustments to the market quotes provided by them and, accordingly, the Company categorized its investment portfolio within Level 2 of the fair value hierarchy. Derivative assets and liabilities – The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back swap agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a market standard discounted cash flow approach. The Company may enter into risk participation agreements with a counterparty bank to accept a portion of the credit risk on interest rate swap related to loans. The fair value for the risk participation agreements is calculated by using a one-sided credit valuation adjustments model that takes into account the total expected asset or liability exposure of the derivatives to the borrowers and the credit of the borrower. Due to the observable nature of the majority of inputs used in deriving the fair value of these derivative contracts, the valuation of derivatives is classified as Level 2. The following fair value hierarchy table presents information about the Company’s financial assets and liabilities measured at fair value on a recurring basis at the dates indicated: March 31, 2020 Fair Value Measurement Using Level 1 Level 2 Level 3 Total Fair Value (Dollars in thousands) Financial assets Investment securities available-for-sale: U.S. Treasury $ — $ 32,833 $ — $ 32,833 Agency — 247,766 — 247,766 Corporate — 176,033 — 176,033 Municipal bonds — 407,097 — 407,097 Collateralized mortgage obligations — 9,656 — 9,656 Mortgage-backed securities — 464,376 — 464,376 Total securities available-for-sale $ — $ 1,337,761 $ — $ 1,337,761 Derivative assets $ — $ 10,961 $ — $ 10,961 Financial liabilities Derivative liabilities $ — $ 11,013 $ — $ 11,013 December 31, 2019 Fair Value Measurement Using Level 1 Level 2 Level 3 Total Fair Value (Dollars in thousands) Financial assets Investment securities available-for-sale: U.S. Treasury $ — $ 63,555 $ — $ 63,555 Agency — 246,358 — 246,358 Corporate — 151,353 — 151,353 Municipal bonds — 397,298 — 397,298 Collateralized mortgage obligations — 9,984 — 9,984 Mortgage-backed securities — 499,836 — 499,836 Total securities available-for-sale $ — $ 1,368,384 $ — $ 1,368,384 Derivative assets $ — $ 2,103 $ — $ 2,103 Financial liabilities Derivative liabilities $ — $ 2,103 $ — $ 2,103 Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Individually evaluated Loans (impaired loans prior to adoption of ASC 326) – A loan is individually evaluated for expected credit losses when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Individually evaluated loans is measured based on the fair value of the underlying collateral or the discounted expected future cash flows. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate and cash. The Company measures impairment on all nonaccrual loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. Other Real Estate Owned – OREO is initially recorded at the fair value less estimated costs to sell at the date of transfer. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the allowance for credit losses. The fair value of individually evaluated loans and other real estate owned were determined using Level 3 assumptions, and represents individually evaluated loan and other real estate owned balances for which a specific reserve has been established or on which a write down has been taken. For real estate loans, generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its individually evaluated loans and other real estate owned to determine fair value. In determining the net realizable value of the underlying collateral for individually evaluated loans, the Company will then discount the valuation to cover both market price fluctuations and selling costs, typically ranging from 7% to 10% of the collateral value, that the Company expected would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions and management’s expertise and knowledge of the client and client’s business. At March 31, 2020 , the Company’s individually evaluated collateral dependent loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisals available to management. The Company completed partial charge-offs on certain individually evaluated loans based on recent real estate or property appraisals and released the related specific reserves during the three months ended March 31, 2020 .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments From time to time, the Company enters into interest rate swap agreements with certain borrowers to assist them in mitigating their interest rate risk exposure associated with the loans they have with the Company. At the same time, the Company enters into identical interest rate swap agreements with another financial institution to mitigate the Company’s interest rate risk exposure associated with the swap agreements it enters into with its borrowers. At March 31, 2020 , the Company had over-the-counter derivative instruments and centrally-cleared derivative instruments with matched terms with an aggregate notional amount of $88.7 million and a fair value of $11.0 million compared with an aggregate notional amount of $76.3 million and a fair value of $2.1 million at December 31, 2019 . The fair value of these agreements are determined through a third party valuation model used by the Company’s counterparty bank, which uses observable market data such as cash LIBOR rates, prices of Eurodollar future contracts and market swap rates. The fair values of these swaps are recorded as components of other assets and other liabilities in the Company’s condensed consolidated balance sheet. Changes in the fair value of these swaps, which occur due to changes in interest rates, are recorded in the Company’s income statement as a component of noninterest income. Since the terms of the swap agreements between the Company and its borrowers have been matched with the terms of swap agreements with another financial institution, the adjustments for the change in their fair value offset each other in noninterest income. Over-the-counter contracts are tailored to meet the needs of the counterparties involved and, therefore, generally contain a greater degree of credit risk and liquidity risk than centrally-cleared contracts, which have standardized terms. Although changes in the fair value of swap agreements between the Company and borrowers and the Company and other financial institutions offset each other, changes in the credit risk of these counterparties may result in a difference in the fair value of these swap agreements. Offsetting over-the-counter swap agreements the Company has with other financial institutions are collateralized with cash, and swap agreements with borrowers are secured by the collateral arrangements for the underlying loans these borrowers have with the Company. During the three months ended March 31, 2020 and 2019 , there were no losses recorded on swap agreements attributable to the change in credit risk associated with a counterparty. All interest rate swap agreements entered into by the Company as of March 31, 2020 and December 31, 2019 are free-standing derivatives and are not designated as hedging instruments. The Company’s credit derivatives result from entering into credit risk participation agreements (“RPAs”) with a counterparty bank to accept a portion of the credit risk on interest rate swaps related to loans. RPAs provide credit protection to the financial institution should the borrower fail to perform on its interest rate swap derivative contract with the financial institution. The credit risk related to these credit derivatives is managed through the Company’s loan underwriting process. RPAs are derivative financial instruments not designated as hedging and are recorded at fair value. Changes in fair value are recognized as a component of noninterest income with a corresponding offset within other assets or other liabilities.

Offsetting [Abstract]
Balance Sheet Offsetting	Balance Sheet Offsetting Derivative financial instruments may be eligible for offset in the consolidated balance sheets, such as those subject to enforceable master netting arrangements or a similar agreement. Under these agreements, the Company has the right to net settle multiple contracts with the same counterparty. The Company offers an interest rate swap product to qualified customers, which are then paired with derivative contracts the Company enters into with a counterparty bank. While derivative contracts entered into with counterparty banks may be subject to enforceable master netting agreements, derivative contracts with customers may not be subject to enforceable master netting arrangements, derivative contracts with customers may not be subject to enforceable master netting arrangements. The Company elected to account for centrally-cleared derivative contracts on a gross basis. With regard to derivative contracts not centrally cleared through a clearinghouse, regulations require collateral to be posted by the party with a net liability position. Parties to a centrally cleared over-the-counter derivative exchange daily payments that reflect the daily change in value of the derivative. These payments are commonly referred to as variation margin and are treated as settlements of derivative exposure rather than as collateral. Financial instruments that are eligible for offset in the consolidated statements of financial condition as of March 31, 2020 are presented in the table below: Gross Amounts Not Offset in the Consolidated Gross Amounts Recognized Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts Presented in the Consolidated Balance Sheets Financial Instruments (1) Cash Collateral (2) Net Amount (Dollars in thousands) March 31, 2020 Financial assets: Derivatives not designated as hedging instruments $ 10,961 $ — $ 10,961 $ — $ — $ 10,961 Total $ 10,961 $ — $ 10,961 $ — $ — $ 10,961 Financial liabilities: Derivatives not designated as hedging instruments $ 11,013 $ — $ 11,013 $ (2,766 ) $ (2,600 ) $ 5,647 Total $ 11,013 $ — $ 11,013 $ (2,766 ) $ (2,600 ) $ 5,647 (1) Represents the fair value of securities pledged with counterparty bank.

Leases

Leases [Abstract]
Leases	Leases The Company accounts for its leases in accordance with ASC 842, which was implemented on January 1, 2019, and requires the Company to record liabilities for future lease obligations as well as assets representing the right to use the underlying leased asset. The Company’s leases primarily represent future obligations to make payments for the use of buildings or space for its operations. Liabilities to make future lease payments are recorded in accrued expenses and other liabilities, while right-of-use assets are recorded in other assets in the Company’s consolidated balance sheets. At March 31, 2020 , all of the Company’s leases were classified as operating leases or short-term leases. Liabilities to make future lease payments and right of use assets are recorded for operating leases and not short-term leases. These liabilities and right-of-use assets are determined based on the total contractual base rents for each lease, which include options to extend or renew each lease, where applicable, and where the Company believes it has an economic incentive to extend or renew the lease. Future contractual base rents are discounted using the rate implicit in the lease or using the Company’s estimated incremental borrowing rate if the rate implicit in the lease is not readily determinable. For leases that contain variable lease payments, the Company assumes future lease payment escalations based on a lease payment escalation rate specified in the lease or the specified index rate observed at the time of lease commencement. Liabilities to make future lease payments are accounted for using the interest method, being reduced by periodic contractual lease payments net of periodic interest accretion. Right-of-use assets for operating leases are amortized over the term of the associated lease by amounts that represent the difference between periodic straight-line lease expense and periodic interest accretion in the related liability to make future lease payments. For the three months ended March 31, 2020 and 2019 , lease expense totaled $3.7 million and $3.4 million , respectively, and was recorded in premises and occupancy expense in the consolidated statements of income. For the three months ended March 31, 2020 and 2019 , lease expense attributable to operating leases totaled approximately $3.2 million and $2.7 million , respectively. Lease expense attributable to short-term leases for the three months ended March 31, 2020 and 2019 totaled approximately $527,000 and $691,000 . Short-term leases are leases that have a term of 12 months or less at commencement.

Revenue Recognition

Revenue Recognition	3 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company earns revenue from a variety of sources. The Company’s principal source of revenue is interest income on loans, investment securities and other interest earning assets, while the remainder of the Company’s revenue is earned from a variety of fees, service charges, gains and losses, and other income, all of which are classified as noninterest income. On January 1, 2018, the Company adopted ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”, and all subsequent amendments that modified ASC 606. ASC 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities, certain noninterest income streams such as gain or loss associated with derivatives, and income from bank owned life insurance. Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Company provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies the related performance obligations by transferring to the customer a good or service. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature and can be canceled at any time by the customer or the Company without penalty, such as a deposit account agreement. These revenue streams are included in noninterest income. The following tables provide a summary of the Company’s revenue streams, including those that are within the scope of ASC 606 and those that are accounted for under other applicable U.S. GAAP: Three Months Ended March 31, 2020 December 31, 2019 March 31, 2019 Within Scope (1) Out of Scope (2) Within Scope (1) Out of Scope (2) Within Scope (1) Out of Scope (2) (Dollars in thousands) Noninterest income: Loan servicing fees $ — $ 480 $ — $ 487 $ — $ 398 Service charges on deposit accounts 1,715 — 1,558 — 1,330 — Other service fee income 311 — 359 — 356 — Debit card interchange income 348 — 367 — 1,071 — Earnings on bank-owned life insurance — 1,336 — 864 — 910 Net gain from sales of loans — 771 — 1,698 — 1,729 Net gain from sales of investment securities — 7,760 — 3,671 — 427 Other income 217 1,537 107 690 192 1,268 Total noninterest income $ 2,591 $ 11,884 $ 2,391 $ 7,410 $ 2,949 $ 4,732 ______________________________ (1) Revenues from contracts with customers accounted for under ASC 606. (2) Revenues not within the scope of ASC 606 and accounted for under other applicable U.S. GAAP requirements. The major revenue streams by fee type that are within the scope of ASC 606 presented in the above tables are described in additional detail below: Service Charges on Deposit Accounts and Other Service Fee Income Service charges on deposit accounts and other service fee income consists of periodic service charges on deposit accounts and transaction based fees such as those related to overdrafts, ATM charges and wire transfer fees. The majority of these revenues are accounted for under ASC 606. Performance obligations for periodic service charges on deposit accounts are typically short-term in nature and are generally satisfied on a monthly basis, while performance obligations for other transaction based fees are typically satisfied at a point in time (which may consist of only a few moments to perform the service or transaction) with no further obligations on behalf of the Company to the customer. Periodic service charges are generally collected monthly directly from the customer’s deposit account, and at the end of a statement cycle, while transaction based service charges are typically collected at the time of or soon after the service is performed. Debit Card Interchange Income Debit card interchange fee income consists of transaction processing fees associated with customer debit card transactions processed through a payment network and are accounted for under ASC 606. These fees are earned each time a request for payment is originated by a customer debit cardholder at a merchant. In these transactions, the Company transfers funds from the debit cardholder’s account to a merchant through a payment network at the request of the debit cardholder by way of the debit card transaction. The related performance obligations are generally satisfied when the transfer of funds is complete, which is generally a point in time when the debit card transaction is processed. Debit card interchange fees are typically received and recorded as revenue on a daily basis. Other Income Other noninterest income includes other miscellaneous fees, which are accounted for under ASC 606; however, much like service charges on deposit accounts, these fees have performance obligations that are very short-term in nature and are typically satisfied at a point in time. Revenue is typically recorded at the time these fees are collected, which is generally upon the completion the related transaction or service provided. Other revenue streams that may be applicable to the Company include gains and losses from the sale of nonfinancial assets such as other real estate owned and property premises and equipment. The Company accounts for these revenue streams in accordance with ASC 610-20, which requires the Company to look to guidance in ASC 606 in the application of certain measurement and recognition concepts. The Company records gains and losses on the sale of nonfinancial assets when control of the asset has been surrendered to the buyer, which generally occurs at a specific point in time. Practical Expedient The Company also employs a practical expedient with respect to contract acquisition costs, which are generally capitalized and amortized into expense. These costs relate to expenses incurred directly attributable to the efforts to obtain a contract. The practical expedient allows the Company to immediately recognize contract acquisition costs in current period earnings when these costs would have been amortized over a period of one year or less. At March 31, 2020 , the Company did not have any material contract assets or liabilities in its consolidated financial statements related to revenue streams within the scope of ASC 606, and there were no material changes in those balances during the reporting period.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Quarterly Cash Dividend and Stock Repurchase Program On April 24, 2020, the Corporation’s Board of Directors declared a cash dividend of $0.25 per share, payable on May 15, 2020 to shareholders of record on May 8, 2020. The Company has suspended its stock repurchase program indefinitely. Pacific Premier Bancorp, Inc. and Opus Bank On January 31, 2020 , the Corporation and the Bank entered into a definitive agreement with Opus, pursuant to which the Company will acquire Opus in an all-stock transaction valued at approximately $1.0 billion , or $26.82 per share, based on a closing price for the Corporation’s common stock of $29.80 as of January 31, 2020. Based on the $18.84 closing price for the Corporation’s common stock as of March 31, 2020, the value of the transaction is approximately $653.3 million , or $16.96 per share. Upon consummation of the acquisition, holders of Opus common stock will have the right receive 0.90 shares of the Corporation’s common stock for each share of Opus stock. We expect to issue approximately 34.7 million shares of our common stock in the Opus acquisition. The Corporation has received the required regulatory approvals from the Board of Governors of the Federal Reserve System and the California Department of Business Oversight for Opus to be merged into the Bank, and for the Bank to exercise trust powers. On May 5, 2020, the Corporation’s and Opus’s shareholders completed approvals required for the acquisition. The transaction is expected to be effective as of June 1, 2020, subject to the satisfaction of customary closing conditions. For additional details, see “ Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Pending Acquisition of Opus .” Impacts of the COVID-19 Pandemic The COVID-19 pandemic was declared a Public Health Emergency of International Concern by the World Health Organization on January 30, 2020. The ongoing COVID-19 pandemic global and national health emergency has caused significant disruption in the United States and international economies and financial markets. The operations and business results of the Company could be materially adversely affected. The extent to which the COVID-19 pandemic impacts our business, asset valuations, results of operations and financial condition, as well as our regulatory capital and liquidity ratios, will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the COVID-19 pandemic and actions taken by governmental authorities and other third parties in response to the COVID-19 pandemic. Material adverse impacts may include all or a combination of valuation impairments on our intangible assets, investments, loans, loan servicing rights and deferred tax assets. Subsequent to March 31, 2020, the Company continued its efforts to support our customers affected by the COVID-19 pandemic and monitor the Bank’s loan portfolio to identify potential at-risk segments and line of credit draws for deviations from normal activity, including but not limited to the following: • Participating in the Small Business Administration’s Paycheck Protection Program (“PPP”) that enabled the Company’s clients to utilize this valuable resource to help meet the costs associated with payroll, mortgage interest, rent and utilities. Through May 6, 2020, our team has executed over 3,700 PPP loans for approximately $1.12 billion through the program. • Implemented a temporary loan modification program for borrowers affected by the COVID-19 pandemic, including payment deferrals, fee waivers and extensions of repayment terms. As of May 6, 2020, we have approved payment deferrals on 80 loans with a total recorded balance of $174.8 million pursuant to the COVID-19 modification program.

Accounting Policies [Abstract]
Recently Issued Accounting Pronouncements	Accounting Standards Adopted in 2020 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This Update replaces the incurred loss impairment model in current U.S. GAAP with a model that reflects current expected credit losses (“CECL”). The CECL model is applicable to the measurement of credit losses on financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. CECL also requires credit losses on available-for-sale debt securities be measured through an allowance for credit losses when the fair value is less than the amortized cost basis. It also applies to off-balance sheet credit exposures. The Update requires that all expected credit losses for financial assets held at the reporting date be measured based on historical experience, current conditions and reasonable and supportable forecasts. The Update also requires enhanced disclosure, including qualitative and quantitative disclosures that provide additional information about significant estimates and judgments used in estimating credit losses. The provisions of this Update became effective for the Company for all annual and interim periods beginning January 1, 2020. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments . This Update was issued as part of an ongoing project on the FASB’s agenda for improving the Codification or correcting for its unintended application. The FASB issued this Update, which is specific to Updates: 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , and 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The amendments in this Update became effective for all interim and annual reporting periods for the Company on January 1, 2020. The Company adopted the provisions within this Update in conjunction with the implementation of Accounting Standard Codification (“ASC”) 326, Financial Instruments - Credit Losses , as discussed below, including: (i) the election to not measure credit losses on accrued interest receivable when such balances are written-off in a timely manner when deemed uncollectable and (ii) the election to not include the balance of accrued interest receivable as part of the amortized cost of a loan, but rather to present it separately in the consolidated statements of financial position. In May 2019, the FASB issued ASU 2019-05, Financial Instruments - Credit Losses (Topic 326) - Targeted Transition Relief . This Update was issued to allow entities that have certain financial instruments within the scope of ASC 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost , to make an irrevocable election to elect the fair value option for those instruments in ASC 825-10, Financial Instruments - Overall upon the adoption of ASC 326, which for the Company was January 1, 2020. The fair value option is not applicable to held-to-maturity debt securities. Entities are required to make this election on an instrument-by-instrument basis. The Company did not elect the fair value option for any of its financial assets upon the adoption of ASC 326 on January 1, 2020. The Company has developed an expected credit loss estimation model in accordance with ASC 326. The Company implemented the model through a cross-functional effort steered by a CECL Committee, related sub-committees and working groups. These committees, sub-committees and working groups, collectively, were primarily comprised of senior management and staff members from our finance, credit, lending, internal audit, risk management and IT functional areas. Depending on the nature of each identified pool of financial assets with similar risk characteristics, the Company employs the use of a probability of default (“PD”) and loss given default (“LGD”) discounted cash flow methodology for commercial real estate and commercial loans, and a loss-rate methodology for retail loans, in order to estimate expected future credit losses. The Company’s model incorporates reasonable and supportable economic forecasts into the estimate of expected credit losses, which requires significant judgment. Management leverages economic projections from a reputable and independent third party to inform its reasonable and supportable economic forecasts. Effective January 1, 2020, the Company adopted the provisions of ASC 326 through the application of the modified retrospective transition approach, and recorded a net decrease of $45.6 million to the beginning balance of retained earnings as of January 1, 2020 for the cumulative effect adjustment, reflecting an initial adjustment to the allowance for credit losses (“ACL”) of $64.0 million , net of related deferred tax assets arising from temporary differences of $18.3 million , commonly referred to as the “Day 1” adjustment. The Day 1 adjustment to the ACL is reflective of expected lifetime credit losses associated with the composition of financial assets within in the scope of ASC 326 as of January 1, 2020, which is comprised of loans held for investment and off-balance sheet credit exposures at January 1, 2020, as well as management’s current expectation of future economic conditions. Management did not have any qualitative adjustments as of January 1, 2020. The Day 1 adjustment was comprised of $55.7 million for loans held for investment and $8.3 million for off-balance sheet commitments for a total of $64.0 million . The Day 1 adjustment to the ACL for loans held for investment consists of $16.1 million for investor loans secured by real estate, $27.6 million for business real estate secured loans, $9.5 million for commercial loans and $2.5 million for retail loans. The majority of the Day 1 increase in the ACL for loans held for investment is attributable primarily to the life of loan loss impact and addition of an allowance on acquired loans based on the methodology discussed above and secondarily to the incorporation of reasonable and supportable economic forecasts into the estimate of expected future credit losses to our commercial real estate and commercial owner-occupied loan portfolios, which have commercial real estate as the primary collateral source and longer contractual maturities relative to our loan portfolio as a whole. Please also see Note 3 - Significant Accounting Policies , for a discussion on the Company’s accounting policy for the ACL, Note 6 - Loans Held for Investment and Note 7 - Allowance for Credit Losses , for additional information on the Company’s ACL, as well as other related disclosures. The Company’s assessment of held-to-maturity and available-for-sale investment securities as of January 1, 2020 indicated that an ACL was not required. The Company determined the likelihood of default on held-to-maturity investment securities was remote, and the amount of expected non-repayment on those investments was zero. The Company also analyzed available-for-sale investment securities that were in an unrealized loss position as of January 1, 2020 and determined the decline in fair value for those securities was not related to credit, but rather related to changes in interest rates and general market conditions. As such, no ACL was recorded for held-to-maturity and available-for-sale securities as of January 1, 2020. In accordance with ASC 326-10-65, upon the adoption of ASC 326, the Company did not reassess purchased loans with credit deterioration (previously classified as purchased credit impaired loans under ASC 310-30), as there were no such loans on January 1, 2020. Additionally, there were no investment securities with previously recorded other-than-temporary impairment as of January 1, 2020. As previously mentioned, in conjunction with the adoption of ASC 326, the Company made an accounting policy election not to measure an ACL on accrued interest receivables in accordance with ASC 326-20-30-5A. When accrued interest receivable is deemed to be uncollectable, the Company promptly reverses such balances through current period earnings in the period they are deemed uncollectable. Additionally, the Company has also elected not to include the balance of accrued interest receivable in the amortized cost basis of financial assets within the scope of ASC 326. Accrued interest receivable will continue to be presented separately in the consolidated financial statements. In February 2019, the U.S. federal bank regulatory agencies approved a final rule modifying their regulatory capital rules and providing an option to phase in over a three-year period the Day 1 adverse regulatory capital effects of ASU 2016-13. Additionally, in March 2020, the U.S. federal bank regulatory agencies issued an interim final rule that provides banking organizations an option to delay the estimated CECL impact on regulatory capital for an additional two years for a total transition period of up to five years to provide regulatory relief to banking organizations to better focus on supporting lending to creditworthy households and businesses in light of recent strains on the U.S. economy as a result of the COVID-19 pandemic. As a result, entities have the option to gradually phase in the full effect of CECL on regulatory capital over a five-year transition period. The Company implemented its CECL model commencing January 1, 2020 and elected to phase in the full effect of CECL on regulatory capital over the five-year transition period. The following table illustrates the impact of the adoption of the CECL model under ASC 326 on the Company’s consolidated statements of financial position as of January 1, 2020: January 1, 2020 Pre-CECL Adoption Impact of CECL Adoption As Reported Under CECL (Dollars in thousands) Assets: Allowance for credit losses on debt securities: Held-to-maturity $ — $ — $ — Available-for-sale — — — Allowance for credit losses on loans: Investor loans secured by real estate 9,027 16,072 25,099 Business loans secured by real estate 5,492 27,572 33,064 Commercial loans 20,118 9,519 29,637 Retail loans 1,061 2,523 3,584 Deferred tax (liabilities) assets (1,371 ) 18,346 16,975 Liabilities: Allowance for credit losses on off-balance sheet credit exposures $ 3,279 $ 8,285 $ 11,564 Stockholders' equity: Retained earnings $ 396,051 $ (45,625 ) $ 350,426 In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848)—Facilitation of the Effects of Reference Rate Reform on Financial Reporting . In response to concerns about structural risks of interbank offered rates (“IBORs”), and, particularly, the risk of cessation of the London Interbank Offered Rate (“LIBOR”), regulators around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction-based and less susceptible to manipulation. The amendments in this Update provide optional guidance for a limited time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting as well as optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The amendments in this Update apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. The amendments in this Update are elective and became effective upon issuance for all entities. An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 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. Once elected for a Topic or an Industry Subtopic, the amendments in this Update must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. An entity may elect to apply the amendments in this Update to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. If an entity elects to apply any of the amendments for an eligible hedging relationship existing as of the beginning of the interim period that includes March 12, 2020, any adjustments as a result of those elections must be reflected as of the beginning of that interim period and recognized in accordance with the guidance in Reference Rate Reform Subtopics 848-30, 848-40 and 848-50 (as applicable). If an entity elects to apply any of the amendments for a new hedging relationship entered into between the beginning of the interim period that includes March 12, 2020, any adjustments as a result of those elections must be reflected as of the beginning of the hedging relationship and recognized in accordance with the guidance in Reference Rate Reform Subtopics 848-30, 848-40 and 848-50 (as applicable). The Company does not currently engage in hedging related transactions, and as such, the amendments included in this Update have not had an impact on the Company’s financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement . The amendments in this Update modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement . The following disclosure requirements for public companies were removed from Topic 820: • The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy • The policy for timing of transfers between levels • The valuation processes for Level 3 fair value measurements The following disclosure requirements for public companies were modified in Topic 820: • The amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date The following disclosure requirements for public companies were added to Topic 820: • The changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period. • The range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this Update became effective for the Company for fiscal years and interim periods within fiscal years beginning on January 1, 2020. This ASU did not have a material effect on the Company’s financial statements. In March 2019, the FASB issued ASU 2019-01, Leases (Topic 842): Codification Improvements. This Update provides clarification on certain aspects of an entity’s implementation of Topic 842 including those that relate to: • Determining the fair value of the underlying asset by lessors that are not manufacturers or dealers. The amendments related to this item carry forward from Topic 840 to Topic 842 an exception that allows lessors who are not manufacturers or dealers to use the cost of the underlying asset as its fair value. • Presentation on the statement of cash flows - sales-type and direct financing leases. The amendments related to this item clarify that all principal payments received on leases by lessors in sales-type or direct financing lease transactions should be reflected in investing activities for entities such as depository and lending institutions within in the scope of Topic 942. • Transition disclosures related to Topic 250, Accounting Changes and Error Corrections. The amendments related to this item clarify the FASB’s original intent by explicitly providing an exception to the paragraph 250-10-50-3 interim disclosure requirements in the Topic 842 transition disclosure requirements, which would otherwise require interim disclosures after the date of adoption of Topic 842 related to the impacts of the change on: (a) income from continuing operations, (b) net income, (c) any other financial statement line item and (d) any affected per-share amounts. The amendments in this Update became effective for the Company for fiscal years and interim periods within fiscal years beginning on January 1, 2020. This ASU did not have a material effect on the Company’s financial statements. Recent Accounting Guidance Not Yet Effective In January 2020, the FASB issued ASU 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323 and Topic 815.
Revenue Recognition	Revenue Recognition. The Company accounts for certain of its revenue streams in accordance with ASC 606 - Revenue from Contracts with Customers . Revenue streams within the scope of and accounted for under ASC 606 include: service charges and fees on deposit accounts, debit card interchange fees, fees from other services the Bank provides its customers and gains and losses from the sale of other real estate owned and property, premises and equipment. ASC 606 requires revenue to be recognized when the Company satisfies related performance obligations by transferring to the customer a good or service. The recognition of revenue under ASC 606 requires the Company to first identify the contract with the customer, identify the performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and finally recognize revenue when the performance obligations have been satisfied and the good or service has been transferred. The majority of the Company’s contracts with customers associated with revenue streams that are within the scope of ASC 606 are considered short-term in nature and can be canceled at any time by the customer or the Bank, such as a deposit account agreement. Other more significant revenue streams for the Company such as interest income on loans and investment securities are specifically excluded from the scope of ASC 606 and are accounted for under other applicable U.S. GAAP.
Goodwill and Core Deposit Intangible	Goodwill and Core Deposit Intangible (“CDI”). CDI assets arising from whole bank acquisitions are amortized on either an accelerated basis, reflecting the pattern in which the economic benefits of the intangible assets is consumed or otherwise used up, or on a straight-line amortization method over their estimated useful lives, which range from 6 to 10 years
Leases	Leases. The Company accounts for its leases in accordance with ASC 842, which requires the Company to record liabilities for future lease obligations as well as assets representing the right to use the underlying leased asset. Leases with a term of 12 months or less are accounted for using straight-line expense recognition with no liability or asset being recorded for such leases. Other than short-term leases, the Company classifies its leases as either finance leases or operating leases. Leases are classified as finance leases when any of the following are met: (a) the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (b) the lease contains an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (c) the term of the lease represents a major part of the remaining life of the underlying asset, (d) the present value of the future lease payments equals or exceeds substantially all of the fair value of the underlying asset or (e) the underling leased asset is expected to have no alternative use to the lessor at the end of the lease term due to its specialized nature. When the Company’s assessment of a lease does not meet the foregoing criteria, and the term of the lease is in excess of 12 months, the lease is classified as an operating lease. Liabilities to make lease payments and right-of-use assets are determined based on the total contractual base rents for each lease, discounted at the rate implicit in the lease or at the Company’s estimated incremental borrowing rate if the rate is not implicit in the lease. The Company measures future base rents based on the minimum payments specified in the lease agreement, giving consideration for periodic contractual rent increases which are based on an escalation rate or a specified index. When future rent payments are based on an index, the Company uses the index rate observed at the time of lease commencement to measure future lease payments. Liabilities to make lease payments are accounted for using the interest method, which are reduced by periodic rent payments, net of interest accretion. Right-of-use assets for finance leases are amortized on a straight-line basis over the term of the lease, while right-of-use assets for operating leases are amortized over the term of the lease by amounts that represent the difference between periodic straight-line lease expense and periodic interest accretion on the related liability to make lease payments. Expense recognition for finance leases is representative of the sum of periodic amortization of the associated right-of-use asset as well as the periodic interest accretion on the liability to make lease payments. Expense recognition for operating leases is recorded on a straight-line basis. As of March 31, 2020, all of the Company’s leases were classified as either operating leases or short-term leases. From time to time the Company leases portions of the space it leases to other parties through sublease transactions. Income received from these transactions is recorded on a straight-line basis over the term of the sublease.
Securities/Securities Held-to-Maturity/Securities Available-for-Sale	Securities. The Company has established written guidelines and objectives for its investing activities. At the time of purchase, management designates the security as either held to maturity, available-for-sale or held for trading based on the Company’s investment objectives, operational needs and intent. The investments are monitored to ensure that those activities are consistent with the established guidelines and objectives. Securities Held-to-Maturity. Investments in debt securities that management has the positive intent and ability to hold to maturity are reported at cost and adjusted for periodic principal payments and the amortization of premiums and accretion of discounts, which are recognized in interest income using the interest method over the period of time remaining to investment’s maturity. Securities Available-for-Sale. Investments in debt securities that management has no immediate plan to sell, but which may be sold in the future, are carried at fair value. Premiums and discounts are amortized using the interest method over the remaining period to the call date for premiums or contractual maturity for discounts and, in the case of mortgage-backed securities, the estimated average life, which can fluctuate based on the anticipated prepayments on the underlying collateral of the securities. Unrealized holding gains and losses, net of tax, are recorded in a separate component of stockholders’ equity as accumulated other comprehensive income. Realized gains and losses on the sales of securities are determined on the specific identification method, recorded on a trade date basis based on the amortized cost basis of the specific security and are included in noninterest income as net gain (loss) on investment securities.
Allowance for Credit Losses on Investment Securities	Allowance for Credit Losses on Investment Securities. The ACL on investment securities is determined for both the held-to-maturity and available-for-sale classifications of the investment portfolio in accordance with ASC 326. For available-for-sale investment securities, the Company performs a quarterly qualitative evaluation for securities in an unrealized loss position to determine if, for those investments in an unrealized loss position, the decline in fair value is credit related or non-credit related. In determining whether a security’s decline in fair value is credit related, the Company considers a number of factors including, but not limited to: (i) the extent to which the fair value of the investment is less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) downgrades in credit ratings; (iv) payment structure of the security, (v) the ability of the issuer of the security to make scheduled principal and interest payments and (vi) general market conditions which reflect prospects for the economy as a whole, including interest rates and sector credit spreads. If it is determined that the unrealized loss can be attributed to credit loss, the Company records the amount of credit loss through a charge to provision for credit losses in current period earnings. However, the amount of credit loss recorded in current period earnings is limited to the amount of the total unrealized loss on the security, which is measured as the amount by which the security’s fair value is below its amortized cost. If it is likely the Company will be required to sell the security in an unrealized loss position, the total amount of the loss is recognized in current period earnings. Unrealized losses deemed non-credit related, the Company records the loss, net of tax, through accumulated other comprehensive income. The Company determines expected credit losses on available-for-sale and held-to-maturity securities through a discounted cash flow approach, using the security’s effective interest rate. However, as previously mentioned, the measurement of credit losses on available-for-sale securities only occurs when, through the Company’s qualitative assessment, it is determined all or a portion of the unrealized loss is deemed to be credit related. The Company’s discounted cash flow approach incorporates assumptions about the collectability of future cash flows. The amount of credit loss is measured as the amount by which the security’s amortized cost exceeds the present value of expected future cash flows. Credit losses on available-for-sale securities are measured on an individual basis, while credit losses on held-to-maturity securities are measured on a collective basis according to shared risk characteristics. Credit losses on held-to-maturity securities are only recognized at the individual security level when the Company determines a security no longer possesses risk characteristics similar to others in the portfolio. The Company does not measure credit losses on an investment’s accrued interest receivable, but rather promptly reverses from current period earnings the amount of accrued interest that is no longer deemed collectable. Accrued interest receivable for investment securities is included in accrued interest receivable balances in the consolidated statements of financial condition.
Loans Held for Investment	Loans Held for Investment. Loans held for investment are loans the Company has the ability and intent to hold until their maturity. These loans are carried at amortized cost, including discounts and premiums on purchased and acquired loans, and net deferred loan origination fees and costs. Purchase discounts and premiums and net deferred loan origination fees and costs on loans are accreted or amortized as an adjustment of yield, using the interest method, over the expected lives of the loans. Income recognition of deferred loan fees and costs is discontinued for loans placed on nonaccrual. Any remaining discounts, premiums, deferred fees or costs and prepayment fees associated with loans that payoff prior to contractual maturity are included in loan interest income in the period of payoff. Loan commitment fees received to originate or purchase a loan are deferred and, if the commitment is exercised, recognized over the life of the loan using the interest method as an adjustment of yield or, if the commitment expires unexercised, recognized as income upon expiration of the commitment. The Company accrues interest on loans using the interest method and only if deemed collectible. Loans for which the accrual of interest has been discontinued are designated as nonaccrual loans. The accrual of interest on loans is discontinued when principal or interest is past due 90 days based on contractual terms of the loan or when, in the opinion of management, there is reasonable doubt as to collection of principal and or interest. When loans are placed on nonaccrual status, all interest previously accrued but not collected is promptly reversed against current period interest income, and as such an ACL for accrued interest receivable is not established. Interest income generally is not recognized on nonaccrual loans unless the likelihood of further loss is remote. Interest payments received on nonaccrual loans are applied as a reduction to the loan principal balance. Interest accruals are resumed on such loans only when they are brought current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to all principal and interest. Investor Loans Secured by Real Estate: • Commercial real estate non-owner-occupied - Commercial real estate (“CRE”) non-owner-occupied includes loans for which the Company holds real property as collateral, but where the borrower does not occupy the underlying property. The primary risks associated with these loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral, significant increases in interest rates, which may make the real e state loan unprofitable to the borrower, changes in market rents and vacancy of the underlying property. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. • Multifamily - Multifamily loans are secured by multi-tenants (5 or more units) residential real properties. Payments on multifamily loans are dependent on the successful operation or management of the properties, and repayment of these loans may be subject to adverse conditions in the real estate market or the economy. • Construction and land - We originate loans for the construction of one-to-four family and multi-family residences and CRE properties in our primary market area. We concentrate our efforts on single homes and small infill projects in established neighborhoods where there is not abundant land available for development. Construction loans are considered to have higher risks due to construction completion and timing risk, and the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. We occasionally originate land loans located predominantly in California for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s inability to pay and the inability of the Company to recover its investment due to a decline in the fair value of the underlying collateral. Business Loans Secured by Real Estate: • Commercial real estate owner-occupied - CRE owner-occupied includes loans for which the Company holds real property as collateral and where the underlying property is occupied by the borrower, such as with a place of business. These loans are primarily underwritten based on the cash flows of the business and secondarily on the real estate. The primary risks associated with CRE owner-occupied loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make the real estate loan unprofitable to the borrower. Real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. • Franchise secured by real estate - Franchise real estate secured loans are business loans secured by real property occupied by franchised restaurants, generally quick-service restaurants . These loans are primarily underwritten based on the cash flows of the business and secondarily on the real estate. • Small Business Administration (“SBA”) - We are approved to originate loans under the SBA’s Preferred Lenders Program (“PLP”). The PLP lending status affords us a higher level of delegated credit autonomy, translating to a significantly shorter turnaround time from application to funding, which is critical to our marketing efforts. We originate loans nationwide under the SBA’s 7(a), SBA Express, International Trade and 504(a) loan programs, in conformity with SBA underwriting and documentation standards. SBA loans are similar to commercial business loans, but have additional credit enhancement provided by the U.S. Small Business Administration, for up to 85% of the loan amount for loans up to $150,000 and 75% of the loan amount for loans of more than $150,000. The Company originates SBA loans with the intent to sell the guaranteed portion into the secondary market on a quarterly basis. Certain loans classified as SBA are secured by commercial real estate property. SBA loans secured by hotels are included in the segment investor loans secured by real estate, and SBA loans secured by all other forms of real estate are included in the business loans secured by real estate segment. All other SBA loans are included in the commercial loans segment below, and are secured by business assets. Commercial Loans: • Commercial and industrial (including franchise commercial loans) (“C&I”) - Loans secured by business assets including inventory, receivables and machinery and equipment to businesses located generally in our primary market area. Loan types includes revolving lines or credit, term loans, seasonal loans and loans secured by liquid collateral such as cash deposits or marketable securities. Franchise credit facilities not secured by real estate and Home Owners’ Association (“HOA”) credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctua te as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers. Retail Loans: • One-to-four family - Although we do not originate, we have acquired first lien single family loans through bank acquisitions. The primary risks of one-to-four family loans include the borrower’s inability to pay, material decreases in the value of the real estate that is being held as collateral and significant increases in interest rates, which may make loans unprofitable to the borrower. • Consumer loans - In addition to consumer loans acquired through our various bank acquisitions, we originate a limited number of consumer loans, generally for banking clients only, which consist primarily of home equity lines of credit, savings account secured loans and auto loans. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral. Acquired Loans. Loans acquired through a purchase or a business combination are recorded at their fair value at the acquisition date. The Company performs an assessment of acquired loans to first determine if such loans have experienced more than insignificant deterioration in credit quality since their origination and thus should be classified and accounted for as purchased credit deteriorated (“PCD”) loans. For loans that have not experienced more than insignificant deterioration in credit quality since origination, referred to as non-PCD loans, the Company records such loans at fair value, with any resulting discount or premium accreted or amortized into interest income over the remaining life of the loan using the interest method. Additionally, upon the purchase or acquisition of non-PCD loans, the Company measures and records an ACL based on the Company’s methodology for determining the ACL. The ACL for non-PCD loans is recorded through a charge to the provision for credit losses in the period in which the loans were purchased or acquired. Acquired loans that are classified as PCD are acquired at fair value, which includes any resulting premiums or discounts. Premiums and discounts are amortized or accreted into interest income over the remaining life of the loan using the interest method. Unlike non-PCD loans, the initial ACL for PCD loans is established through an adjustment to the acquired loan balance and not through a charge to the provision for credit losses in the period in which the loans were acquired. The ACL for PCD loans is determined with the use of the Company’s ACL methodology. Characteristics of PCD loans include: delinquency, downgrade in credit quality since origination, loans on nonaccrual status and/or other factors the Company may become aware of through its initial analysis of acquired loans that may indicate there has been more than insignificant deterioration in credit quality since a loan’s origination. As of January 1, 2020 and March 31, 2020, there were no loans classified as PCD loans. Subsequent to acquisition, the ACL for both non-PCD and PCD loans are determined with the use of the Company’s ACL methodology in the same manner as all other loans.
Allowance for Credit Losses on Loans	Allowance for Credit Losses on Loans. The Company accounts for credit losses on loans in accordance with ASC 326, which requires the Company to record an estimate of expected lifetime credit losses for loans at the time of origination or acquisition. The ACL is maintained at a level deemed appropriate by management to provide for expected credit losses in the portfolio as of the date of the consolidated statements of financial condition. Estimating expected credit losses requires management to use relevant forward-looking information, including the use of reasonable and supportable forecasts. The measurement of the ACL is performed by collectively evaluating loans with similar risk characteristics. The Company measures the ACL on commercial real estate loans and commercial loans using a discounted cash flow approach, and a historical loss rate methodology is used to determine the ACL on retail loans. The Company’s discounted cash flow methodology incorporates a probability of default and loss given default model, as well as expectations of future economic conditions, using reasonable and supportable forecasts. Together, the probability of default and loss given default model with the use of reasonable and supportable forecasts generate estimates for cash flows expected to be collected over the estimated life of a loan. Estimates of future expected cash flows ultimately reflect assumptions made concerning net credit losses over the life of a loan. The use of reasonable and supportable forecasts requires significant judgment, such as selecting forecast scenarios and related scenario-weighting, as well as determining the appropriate length of the forecast horizon. Management leverages economic projections from a reputable and independent third party to inform and provide its reasonable and supportable economic forecasts. Other internal and external indicators of economic forecasts may also be considered by management when developing the forecast metrics. The Company’s ACL model reverts to long-term average loss rates for purposes of estimating expected cash flows beyond a period deemed reasonable and supportable. The Company forecasts economic conditions and expected credit losses over a two-year time horizon before reverting to long-term average loss rates. The duration of the forecast horizon, the period over which forecasts revert to long-term averages, the economic forecasts that management utilizes, as well as additional internal and external indicators of economic forecasts that management considers, may change over time depending on the nature and composition of our loan portfolio. Changes in economic forecasts, in conjunction with changes in loan specific attributes, impact a loan’s probability of default and loss given default, which can drive changes in the determination of the ACL. Expectations of future cash flows are discounted at the loan’s effective interest rate. The resulting ACL represents the amount by which the loan’s amortized cost exceeds the net present value of a loan’s discounted cash flows. The ACL is recorded through a charge to provision for credit losses and is reduced by charge-offs, net of recoveries on loans previously charged-off. It is the Company’s policy to charge-off loan balances at the time they have been deemed uncollectable. Please also see Note 7 - Allowance for Credit Losses , of these consolidated financial statements for additional discussion concerning the Company’s ACL methodology. The Company’s ACL model also includes adjustments for qualitative factors, where appropriate. Since historical information (such as historical net losses and economic cycles) may not always, by themselves, provide a sufficient basis for determining future expected credit losses; the Company periodically considers the need for qualitative adjustments to the ACL. Qualitative adjustments may be related to and include, but not limited to factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios and changes in portfolio segmentation and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. The Company has a credit portfolio review process designed to detect problem loans. Problem loans are typically those of a substandard or worse internal risk grade, and may consist of loans on nonaccrual status, troubled debt restructurings (“TDRs”), loans where the likelihood of foreclosure on underlying collateral has increased, collateral dependent loans and other loans where concern or doubt over the ultimate collectability of all contractual amounts due has become elevated. Such loans may, in the opinion of management, be deemed to no longer possess risk characteristics similar to other loans in the loan portfolio, and as such may require individual evaluation to determine an appropriate ACL for the loan. When a loan is individually evaluated, the Company typically measures the expected credit loss for the loan based on a discounted cash flow approach, unless the loan has been deemed collateral dependent. Collateral dependent loans are loans where the repayment of the loan is expected to come from the operation of and/or eventual liquidation of the underlying collateral. The ACL for collateral dependent loans is determined using estimates for the fair value of the underlying collateral, less costs to sell. Although management uses the best information available to derive estimates necessary to measure an appropriate level of ACL, future adjustments to the ACL may be necessary due to economic, operating, regulatory and other conditions that may extend beyond the Company’s control. Various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL and credit review process. Such agencies may require the Company to recognize additions to the allowance based on judgments different from those of management. The Company has segmented the loan portfolio according to loans that share similar attributes and risk characteristics. Each segment possesses varying degrees of risk based on, among other things, the type of loan, the type of collateral and the sensitivity of the borrower or industry to changes in external factors such as economic conditions. These segment groupings are: investor real estate secured loans, business real estate secured loans, commercial loans and retail loans. Within each segment grouping there are various classes of loans as disclosed below. The Company determines the ACL for loans based on this more detailed loan segmentation and classification. At March 31, 2020 the Company had the following detailed segmentation on classes of loans:
Troubled Debt Restructurings	Troubled Debt Restructurings (“TDRs”). From time-to-time, the Company makes modifications to certain loans when a borrower is experiencing financial difficulty. These modifications are made to alleviate temporary impairments in the borrower’s financial condition and/or constraints on the borrower’s ability to repay the loan, and to minimize potential losses to the Company. Modifications typically include: changes in the amortization terms of the loan, reductions in interest rates, acceptance of interest only payments and, in limited cases, concessions to the outstanding loan balance. Such loans are typically placed on nonaccrual status and are returned to accrual status when all contractual amounts past due have been brought current, the loan has performed under the modified terms of the loan agreement for a period of at least six months and the ultimate collectability of all contractual amounts due under the modified terms of the loan agreement is no longer in doubt. The Company typically measures the ACL for TDRs on an individual basis when the loans are deemed to no longer share similar risk characteristics with other loans in the portfolio. The determination of the ACL for TDRs is based on a discounted cash flow approach for both those measured collectively and individually, unless the loan is deemed collateral dependent, which requires measurement of the ACL based on the fair value of the collateral less cost to sell.
Other Real Estate Owned	Other Real Estate Owned (“OREO”). Real estate properties acquired through, or in lieu of, loan foreclosure are recorded at fair value, less cost to sell, with any excess of the loan’s amortized cost balance over the fair value of the property recorded as a charge against the ACL. The Company obtains an appraisal and/or market valuation on all other real estate owned at the time of possession. After foreclosure, valuations are periodically performed by management. Any subsequent declines in fair value are recorded as a charge to non-interest expense in current period earnings with a corresponding write-down to the asset. All legal fees and direct costs, including foreclosure and other related costs are expensed as incurred.
Use of Estimates	Use of Estimates
Fair Value Measurement	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Individually evaluated Loans (impaired loans prior to adoption of ASC 326) – A loan is individually evaluated for expected credit losses when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Individually evaluated loans is measured based on the fair value of the underlying collateral or the discounted expected future cash flows. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate and cash. The Company measures impairment on all nonaccrual loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. Other Real Estate Owned – OREO is initially recorded at the fair value less estimated costs to sell at the date of transfer. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the allowance for credit losses. The fair value of individually evaluated loans and other real estate owned were determined using Level 3 assumptions, and represents individually evaluated loan and other real estate owned balances for which a specific reserve has been established or on which a write down has been taken. For real estate loans, generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its individually evaluated loans and other real estate owned to determine fair value. In determining the net realizable value of the underlying collateral for individually evaluated loans, the Company will then discount the valuation to cover both market price fluctuations and selling costs, typically ranging from 7% to 10%
