The principal business of the Company is attracting deposits from the general public and investing those deposits, together with funds generated from operations and borrowings, primarily in business loans and commercial real estate loans. At December 31, 2021, the Company had 61 full-service depository branches located in the western United States in major metropolitan markets in California, Washington, Oregon, Arizona, and Nevada. The Company also offers IRA custodial and maintenance services through its Pacific Premier Trust division, which serves as a custodian for self-directed IRAs, the funds of which account owners use for self-directed investments in various alternative asset classes. Additionally, the Company provides commercial escrow services through its Commerce Escrow division, which facilitates tax-deferred commercial exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). The Company is subject to the regulations of certain governmental agencies, and undergoes periodic examinations by those regulatory authorities. Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Corporation and its wholly-owned subsidiary the Bank. The Company is organized and operates as a single reporting segment, principally engaged in the commercial banking business. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company consolidates voting entities in which the Company has control through voting interests or entities through which the Company has a controlling financial interest in a variable interest entity (“VIE”). The Company evaluates its interests in these entities to determine whether they meet the definition of a VIE and whether the Company is required to consolidate these entities. A VIE is consolidated by its primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest the Company holds could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size, and form of the Company's involvement with the VIE. See Note 10 - Variable Interest Entities for additional information. Effective June 1, 2020, the Corporation completed the acquisition of Opus Bank (“Opus”), a California-chartered state bank headquartered in Irvine, California, for a total consideration of approximately $749.6 million. See further discussion in Note 25 – Acquisitions . Basis of Financial Statement Presentation. The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). Certain amounts in the financial statements and related footnote disclosures for the prior years have been reclassified to conform to the current presentation with no impact to previously reported net income or stockholders’ equity. Use of Estimates. The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates, and those estimates may change as new information is obtained. The following discussion provides a summary of the Company’s significant accounting policies: Cash and Cash Equivalents. Cash and cash equivalents include cash on hand, cash balances due from banks, and federal funds sold. Interest-bearing deposits with financial institutions represent primarily cash held at the Federal Reserve Bank of San Francisco. The Board of Governors of the Federal Reserve System (“Federal Reserve”) has cash reserve requirements for depository institutions based on the amount of deposits held. At December 31, 2021, the Bank had no required balance by the Federal Reserve. The Company maintains amounts due from banks that exceed federally insured limits. The Company has not experienced any losses in such accounts. 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 or available-for-sale 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. The Company accounts for transfers of debt securities from the available-for-sale classification to the held-to-maturity classification at fair value on the date of transfer. Any associated unrealized gains or losses on such securities as of the date of transfer become part of the security’s amortized cost and are subsequently amortized or accreted into interest income over the remaining life of the security using the interest method. In addition, the related unrealized gains and losses included in accumulated other comprehensive income on the date of transfer are also subsequently amortized or accreted into interest income over the remaining life of the security using the interest method. 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 using 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 from sales of investment securities. Allowance for Credit Losses on Investment Securities. The allowance for credit losses (“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, which became effective for the Company on January 1, 2020. The ACL for investment securities is evaluated on a quarterly basis. The ACL for held-to-maturity investment securities is recorded at the time of purchase or acquisition, representing the Company’s best estimate of current expected credit losses (“CECL”) as of the date for the consolidated statements of financial condition. The ACL for held-to-maturity investment securities is determined on a collective basis, based on shared risk characteristics, and is determined at the individual security level when the Company deems a security to no longer possess shared risk characteristics. For investment securities where the Company has reason to believe the credit loss exposure is remote, such as those guaranteed by the U.S. government or other government enterprises, a zero credit loss assumption is applied. For available-for-sale investment securities, the Company performs a 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, or a portion thereof, is credit related, 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 are recorded, 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. 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. Equity Investments . Equity investments that have readily determinable fair values are carried at fair value with changes in fair value recognized in current period earnings as a component of noninterest income. Equity investments that do not have readily determinable fair values are carried at cost, adjusted for any observable price changes in orderly transactions for identical or similar investments of the same issuer. Such investments are also recorded net of any previously recognized impairment. Certain equity securities the Company holds, such as investments in the stock of the Federal Home Loan Bank and the Federal Reserve Bank of San Francisco are carried at cost, less any previously recognized impairment. Investment in these securities is restricted to member banks and the securities are not actively traded on an exchange. The Company applies the equity method of accounting to investments in the equity of certain entities where it is deemed to have the ability to exercise significant influence over the entity, but does not control the entity, such as when its ownership interest is between 20% and 50%. Further, the Company also applies the equity method of accounting to equity investments it makes in limited partnerships and limited liability companies when its ownership interest in such entities exceeds 5% or when the Company has the ability to exercise significant influence over the partnership. Such investments typically reflect equity interests in various partnerships that make investments qualifying for credit under the Community Reinvestment Act (“CRA”). The Company records its share of the operating results associated with equity method investments, based on the most recent information available from the investee, in other noninterest income in the consolidated statements of income. Federal Home Loan Bank Stock. The Bank is a member of the Federal Home Loan Bank (“FHLB”) System. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income. Federal Reserve Bank Stock. The Bank is a member of the Federal Reserve Bank of San Francisco (the “FRB”). FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income. Loans Held for Sale. Loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination or when the determination is made to sell the loan. Such loans are recorded at the lower of cost or fair value. Gains or losses are recognized upon the sale of the loans on a specific identification basis. Origination fees and costs are deferred until the time of sale and are included in the calculation of the gain or loss on the sale of the loan. Loan Servicing Assets. Servicing assets are related to SBA loans sold and are recognized at the time of sale when servicing is retained with the income statement effect recorded in gains on sales of SBA loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of estimated servicing costs, over the estimated life of the loan. The Company’s servicing costs approximates the industry average servicing costs of approximately 40 basis points. The servicing assets are subsequently amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Company periodically evaluates servicing assets for impairment based upon the fair value of the assets as compared to their carrying amount. The Company typically sells the guaranteed portion of SBA loans and retains the unguaranteed portion (“retained interest”). A portion of the premium on sale of SBA loans is recognized as gain on sale of loans at the time of the sale by allocating the carrying amount between the asset sold and the retained interest, based on their relative fair values. The remaining portion of the premium is recorded as a discount on the retained interest and is amortized over the remaining life of the loan as an adjustment to yield. The retained interest, net of any discount, are included in loans held for investment—net of allowance for credit losses in the accompanying 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, net of discounts and premiums on acquired and purchased 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 in interest income as an adjustment of yield, using the interest method, over the expected life of the loans. Amortization of deferred loan fees and costs are discontinued for loans that are placed on nonaccrual. Any remaining discounts, premiums, deferred fees or costs, and prepayment fees associated with loan payoffs 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 the collection of principal and or interest. When loans are placed on nonaccrual status, all previously accrued and uncollected interest 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 deemed 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 was effective for the Company on January 1, 2020. ASC 326 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 and not 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 probability of default and loss given default based on economic forecast scenarios over a two-year time horizon before reverting to long-term historical average loss rates over a period of three years. 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 for term loans represents the amount by which the loan’s amortized cost exceeds the net present value of a loan’s discounted cash flows expected to be collected. The ACL for credit facilities is determined by discounting estimates for cash flows not expected to be collected. 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 uncollectible. 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 itself, 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 backtesting, 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, which have exhibited a deterioration in credit quality 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 the 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. Additionally, 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 ACL based on judgments different from those of management. Please also see Note 5 - Allowance for Credit Losses , of these Consolidated Financial Statements for additional discussion concerning the Company’s ACL methodology, including discussion concerning economic forecasts used in the determination of the ACL. 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 loans secured by real estate, business loans secured by real estate, 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 December 31, 2021, the Company had the following segments and 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, changes in market rents, and vacancy of the underlying property, any of 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. • Multifamily - Multifamily loans are secured by multi-unit (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 multifamily 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. Risks associated with these loans include material decreases in the value of real estate being held as collateral, and the borrower’s inability to pay as a result of increases in interest rates or decreases in cash flow from the underlying business. • 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. 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. Loan types include revolving lines of 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 commercial and industrial loans. We also issue letters of credit on behalf of our customers. Risk associated with commercial and industrial loans 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, and occasionally upon other borrower assets and guarantor assets. The fair value of the collateral securing these loans may fluctuate 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 first lien single family loans, 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. Risk arises with these loans in the borrower’s inability to pay an

Regulatory Capital Requirements under Banking Regulations [Abstract]
Regulatory Capital Requirements and Other Regulatory Matters	Regulatory Capital Requirements and Other Regulatory Matters The Corporation and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation and the Bank must meet specific capital guidelines that involve quantitative measures of the Corporation’s and the Bank’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Corporation’s and the Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain capital in order to meet certain capital ratios to be considered adequately capitalized or well capitalized under the regulatory framework for prompt corrective action. As of the most recent formal notification from the Federal Reserve, the Bank was categorized as “well capitalized.” There are no conditions or events since that notification that management believes have changed the Bank’s categorization. The Company and the Bank are required to meet risk-based capital standards under the revised capital framework of the Basel Committee on Banking Supervision, generally referred to as “Basel III”, administered by their respective regulatory authorities with a phase-in period beginning on January 1, 2015 and ending on January 1, 2019. The Basel III final capital framework requires all banking organizations to maintain a capital conservation buffer of 2.50% above the minimum risk-based capital requirements in order to avoid certain limitations on capital distributions, stock repurchases, and discretionary bonus payments to executive officers. The capital conservation buffer is exclusively comprised of Common Equity Tier capital, and it applies to each of the three risk-based capital ratios but not to the leverage ratio. At December 31, 2021, the Company and Bank are in compliance with the capital conservation buffer requirement and exceeded the minimum Common Equity Tier 1, Tier 1 and total capital ratio, inclusive of the fully phased-in capital conservation buffer, of 7.0%, 8.5% and 10.5%, respectively, and the Bank qualified as “well-capitalized” for purposes of the federal bank regulatory prompt corrective action regulations. 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 the CECL accounting standard. 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. The capital relief in the interim is calibrated to approximate the difference in allowances under CECL relative to the incurred loss methodology for the first two years of the transition period using a 25% scaling factor. The cumulative difference at the end of the second year of the transition period is then phased in to regulatory capital at 25% per year over a three-year transition period. The final rule was adopted and became effective in September 2020. As a result, entities may gradually phase in the full effect of CECL on regulatory capital over a five-year transition period. The Company implemented the 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. For regulatory capital purposes, the subordinated debentures of the Corporation and the Bank are included in Tier 2 capital at December 31, 2021 and 2020. In 2021, the total capital ratios of the Corporation and the Bank were impacted by the redemptions of subordinated debentures during the second and third quarter and remained above the regulatory minimum required for capital adequacy purposes, inclusive of capital conservation buffer. See Note 13 - Subordinated Debentures for additional information. As defined in applicable regulations and set forth in the table below, the Corporation and the Bank continue to exceed the regulatory capital minimum requirements, and the Bank continues to exceed the “well capitalized” standards and the required conservation buffer at the dates indicated: Actual Minimum Required for Capital Adequacy Purposes Inclusive of Capital Conservation Buffer Minimum Required For Well Capitalized Requirement (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio December 31, 2021 Pacific Premier Bancorp, Inc.

During the year, the Company transferred approximately $326.5 million of municipal bonds, which the Company intends and has the ability to hold to maturity, from available-for sale to held-to-maturity securities. The transfer of these securities was accounted for at fair value. These securities had a net carrying amount of $319.9 million with a pre-tax unrealized loss of $6.6 million, which was reflected as a discount on the date of transfer. This discount, as well as the related unrealized loss in accumulated other comprehensive income, is amortized into interest income as a yield adjustment over the remaining term of the securities. The amortization of the unrealized loss reported in accumulated other comprehensive income offsets the effect on interest income of the amortization of the discount. No gains or losses were recorded at the time of transfer. Investment securities with carrying values of $130.7 million and $147.3 million as of December 31, 2021 and 2020, respectively, were pledged to secure public deposits, other borrowings, and for other purposes as required or permitted by law. Unrealized Gains and Losses Unrealized gains and losses on investment securities available-for-sale are recognized in stockholders’ equity as accumulated other comprehensive income or loss. At December 31, 2021, the Company had accumulated other comprehensive loss of $4.7 million, or $3.3 million net of tax, compared to accumulated other comprehensive income of $84.4 million, or $60.3 million net of tax, at December 31, 2020. For investment securities transferred from available-for-sale to held-to-maturity, the unrealized gains and losses at the date of transfer continue to be reported in stockholders’ equity as accumulated other comprehensive income and are amortized over the remaining lives of the securities with an offsetting entry to interest income as an adjustment of yield. At December 31, 2021, the gross unrealized loss on municipal bonds transferred from available-for-sale to held-to-maturity in accumulated other comprehensive loss was $6.3 million, or $4.5 million net of tax. The table below shows the number, fair value, and gross unrealized holding losses of the Company’s investment securities available-for-sale in an unrealized loss position for which an allowance for credit losses has not been recorded as of the dates indicated, aggregated by investment category and length of time in a continuous loss position.

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, through the Company’s qualitative assessment, to be credit related. Non-credit related declines in fair value of available-for-sale investment securities, which may be attributed to changes in interest rates and other market related factors, are not recorded through an ACL. Such declines are recorded as an adjustment to accumulated other comprehensive income, net of tax. 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. Credit losses on held-to-maturity investment securities are recorded at the time of purchase or acquisition and when the Company has designated securities as held-to-maturity. Credit losses on held-to-maturity investment securities are representative of current expected credit losses that may be incurred over the life of the investment. The Company determines credit losses on both available-for-sale and held-to-maturity 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. During the second quarter of 2020, the Company acquired $829.9 million of available-for-sale securities in connection with the acquisition of Opus. Such securities were evaluated and it was determined that there were no investment securities classified as purchase credit deteriorated upon acquisition and, as a result, no allowance for credit losses was recorded. At December 31, 2021, the Company had an ACL of $22,000 for held-to-maturity investment securities classified as municipal bonds, which primarily consisted of the securities transferred from available-for-sale during the third and fourth quarters of 2021. There was no ACL for held-to-maturity investment securities at December 31, 2020. The Company recognized $22,000 of provision for credit losses for held-to-maturity investment securities during the year ended December 31, 2021. There was no provision for credit losses recognized for held-to-maturity investment securities during the year ended December 31, 2020. The following table presents a rollforward by major security type of the allowance for credit losses on the Company's held-to-maturity debt securities as of, and for the periods indicated: For the Year Ended December 31, 2021 (Dollars in thousands) Balance, December 31, 2020 Provision for Credit Losses Balance, December 31, 2021 Investment securities held-to-maturity: Municipal bonds $ — $ 22 $ 22 The Company had no ACL for available-for-sale or investment securities at December 31, 2021 and 2020. As of December 31, 2021 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 a qualitative assessment of these investments as of December 31, 2021, and does not believe the declines in fair value were credit related. There were no provision for credit losses recognized for investment securities during the year ended December 31, 2021 and 2020. There were no other than temporary impairment losses recognized for investment securities for the year ended December 31, 2019. At December 31, 2021 and 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 December 31, 2021 and 2020, there were no securities purchased with deterioration in credit quality since their origination. At December 31, 2021 and 2020, there were no collateral dependent available-for-sale or held-to-maturity securities.

Receivables [Abstract]
Loans Held for Investment	Loans Held for Investment The company’s loan portfolio is segmented according to loans that share similar attributes and risk characteristics. Investor loans secured by real estate include CRE non-owner-occupied, multifamily, construction, and land, as well as SBA loans secured by real estate, which are loans collateralized by hotel/motel real property. Business loans secured by real estate are loans to businesses that are collateralized by real estate where the operating cash flow of the business is the primary source of repayment. This loan portfolio includes CRE owner-occupied, franchise loans secured by real estate, and SBA loans secured by real estate, which are collateralized by real property other than hotel/motel real property. Commercial loans are loans to businesses where the operating cash flow of the business is the primary source of repayment. This loan portfolio includes commercial and industrial loans, franchise loans non-real estate secured, and SBA loans non-real estate secured. Retail loans include single family residential and consumer loans. Single family residential loans include home equity lines of credit, as well as second trust deeds. The following table presents the composition of the loan portfolio as of the dates indicated: December 31, (Dollars in thousands) 2021 2020 Investor loans secured by real estate CRE non-owner-occupied $ 2,771,137 $ 2,675,085 Multifamily 5,891,934 5,171,356 Construction and land 277,640 321,993 SBA secured by real estate 46,917 57,331 Total investor loans secured by real estate 8,987,628 8,225,765 Business loans secured by real estate CRE owner-occupied 2,251,014 2,114,050 Franchise real estate secured 380,381 347,932 SBA secured by real estate 69,184 79,595 Total business loans secured by real estate 2,700,579 2,541,577 Commercial loans Commercial and industrial 2,103,112 1,768,834 Franchise non-real estate secured 392,576 444,797 SBA non-real estate secured 11,045 15,957 Total commercial loans 2,506,733 2,229,588 Retail loans Single family residential 95,292 232,574 Consumer 5,665 6,929 Total retail loans 100,957 239,503 Gross loans held for investment (1) 14,295,897 13,236,433 Allowance for credit losses for loans held for investment (197,752) (268,018) Loans held for investment, net $ 14,098,145 $ 12,968,415 Total unfunded loan commitments $ 2,507,911 $ 1,947,250 Loans held for sale, at lower of cost or fair value $ 10,869 $ 601 ____________________________________________________ (1) Includes net deferred origination fees of $3.5 million and $2.6 million, and unaccreted fair value net purchase discounts of $77.1 million and $113.8 million as of December 31, 2021 and December 31, 2020 respectively. The Company originates SBA loans with the intent to sell the guaranteed portion of the loans prior to maturity and, therefore, designates them as held for sale. From time to time, the Company may purchase or sell other types of loans in order to manage concentrations, maximize interest income, change risk profiles, improve returns, and generate liquidity. The Company participated in the SBA Paycheck Protection Program (“PPP”) under the CARES Act during the second quarter of 2020 and originated SBA PPP loans. At June 30, 2020, the Company’s SBA PPP loan balance was $1.13 billion. In July 2020, the Company concluded the sale of its entire SBA PPP loan portfolio with an aggregate amortized cost of $1.13 billion to a seasoned and experienced nonbank lender and servicer of SBA loans, resulting in improved balance sheet liquidity and a gain on sale of approximately of $18.9 million, net of net deferred origination fees and net purchase discounts. Loans Serviced for Others and Loan Securitization The Company generally retains the servicing rights of the guaranteed portion of SBA loans sold, for which the Company records servicing assets at fair value within its other assets category. Servicing assets are subsequently measured using the amortization method and amortized to noninterest income in proportion to and over the period of estimated net servicing income. At December 31, 2021 and 2020, the servicing assets totaled $3.8 million and $5.3 million, respectively, and were included in other assets on the Company’s consolidated statements of financial condition. Servicing assets are evaluated for impairment based upon the fair value of the servicing 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. The fair value of retained servicing rights is generally evaluated at the loan level using a discounted cash flow analysis utilizing current market assumptions derived from the secondary market. Key modeling assumptions include interest rates, prepayment assumptions, discount rate, and servicing cost. At December 31, 2021, and 2020, the Company determined that no valuation allowance was necessary. Opus entered into securitization sales on December 23, 2016 with the Federal Home Loan Mortgage Corporation (“Freddie Mac”). The transaction involved the sale of $509.0 million in originated multifamily loans through a Freddie Mac-sponsored transaction. One class of Freddie Mac guaranteed structured pass-through certificates was issued and purchased entirely by Opus. In connection with the Opus acquisition, the Company's continuing involvement includes sub-servicing responsibilities, general representations and warranties, and reimbursement obligations. Servicing responsibilities on loan sales generally include obligations to collect and remit payments of principal and interest, provide foreclosure services, manage payments of taxes and insurance premiums, and otherwise administer the underlying loans. In connection with the securitization transaction, Freddie Mac was designated as the master servicer and appointed the Company to perform sub-servicing responsibilities, which generally include the servicing responsibilities described above with the exception of the servicing of foreclosed or defaulted loans. The overall management, servicing, and resolution of defaulted loans and foreclosed loans are separately designated to the special servicer, a third-party institution that is independent of the master servicer and the Company. The master servicer has the right to terminate the Company in its role as sub-servicer and direct such responsibilities accordingly. General representations and warranties associated with loan sales and securitization sales require the Company to uphold various assertions that pertain to the underlying loans at the time of the transaction, including, but not limited to, compliance with relevant laws and regulations, absence of fraud, enforcement of liens, no environmental damages, and maintenance of relevant environmental insurance. Such representations and warranties are limited to those that do not meet the quality represented at the transaction date and do not pertain to a decline in value or future payment defaults. In circumstances where the Company breaches its representations and warranties, the Company would generally be required to cure such instances through a repurchase or substitution of the subject loan(s). To the extent the ultimate resolution of defaulted loans results in contractual principal and interest payments that are deficient, the Company is obligated to reimburse Freddie Mac for such amounts, not to exceed 10% of the original principal amount of the loans comprising the securitization pool at the closing date of December 23, 2016. The liability recorded for Company’s exposure to the reimbursement agreement with Freddie Mac was $338,000 and $448,000 as of December 31, 2021 and 2020, respectively. Loans sold and serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balances of loans and participations serviced for others were $565.8 million and $686.0 million at December 31, 2021 and 2020, respectively. Included in those totals are multifamily loans transferred through securitization with Freddie Mac of $78.1 million and $99.4 million at December 31, 2021 and 2020, respectively, and SBA participations serviced for others totaling $365.6 million and $421.7 million at December 31, 2021 and 2020, respectively. Concentration of Credit Risk As of December 31, 2021, the Company’s loan portfolio was primarily collateralized by various forms of real estate and business assets located principally in California. The Company’s loan portfolio contains concentrations of credit in multifamily, CRE non-owner-occupied, CRE owner-occupied, and C&I 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. 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 $848.1 million for secured loans and $508.8 million for unsecured loans at December 31, 2021. In order to manage concentration risk, the Bank maintains a house lending limit well below these statutory maximums. At December 31, 2021, the Bank’s largest aggregate outstanding balance of loans to one borrower was $188.5 million, primarily comprised of an asset-based line of credit. Credit Quality and Credit Risk The Company’s credit quality and credit risk is managed in two distinct areas. The first is the loan origination process, wherein the Bank underwrites credit and chooses which types and levels of risk it is willing to accept. The Company maintains a credit policy which addresses many related topics, sets forth maximum tolerances for key elements of loan risk, and indicates appropriate protocols for identifying and analyzing these risk elements. The policy 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 all key risk factors are analyzed, with most underwriting including a global cash flow analysis of the prospective borrowers. The second area 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 appropriate fashion. Credit risk is monitored and managed within the loan portfolio by the Company’s portfolio managers based on both the credit policy and a credit and portfolio review policy. This latter policy requires a program of financial data collection and analysis, thorough loan reviews, property and/or business inspections, monitoring of portfolio concentrations and trends, and incorporation of current business and economic conditions. The portfolio managers also monitor 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. Most individual loans, excluding the homogeneous loan portfolio, are reviewed at least annually, 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 federal banking 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 an acceptable level of credit quality that contains no well-defined deficiencies or weaknesses. • 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 through foreclosure are also classified as substandard assets. • 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 biennial 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.

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 loan portfolio. These loans are typically identified from those that have exhibited deterioration in credit quality, 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, downgraded to substandard or worse, 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, or that have been identified as collateral dependent, 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 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 December 31, 2021, $31.3 million of loans were individually evaluated, and the ACL attributed to such loans was $1.5 million. At December 31, 2021, $12.4 million of individually evaluated loans were evaluated using a discounted cash flow approach, and $18.9 million of individually evaluated loans were evaluated based on the underlying value of the collateral. All individually evaluated loans were on nonaccrual status at December 31, 2021. As of December 31, 2020, $29.2 million of loans were individually evaluated, and the ACL attributed to such loans was $126,000. At December 31, 2020, $15.2 million of the individually evaluated loans were evaluated using a discounted cash flow approach and $14.0 million were evaluated based on the underlying value of collateral. All individually evaluated loans were on nonaccrual status at December 31, 2020. 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 TDRs. 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. In most cases, the Company initially places TDRs on nonaccrual status, and they may be returned to accrual status when the loans are brought current, have performed in accordance with the restructured contractual terms for a period of at least six months, and the ultimate collectability of the total contractual restructured principal and interest are no longer in doubt. At December 31, 2021, the Company had $17.3 million TDR loans. During the year ended December 31, 2021, there were six loans totaling $17.3 million modified as TDRs, which were comprised of three CRE owner-occupied loans and one C&I loan totaling $5.2 million belonging to one borrower relationship with the terms modified due to bankruptcy, and two franchise non-real estate secured loans totaling $12.1 million belonging to another borrower relationship with the terms modified for payment deferral. During the year ended December 31, 2021, the three CRE owner-occupied loans and one C&I loan classified as TDRs were in payment default and all TDRs were on nonaccrual status as of December 31, 2021. At December 31, 2020, there were no loans classified as TDRs. During the year ended December 31, 2020, there were two loans modified as TDRs that experienced payment defaults after modifications within the previous 12 months, consisting of a C&I loan of $1.3 million and a franchise non-real estate secured loan of $344,000 that were charged off in 2020. The CARES Act, signed into law on March 27, 2020, permits financial institutions to suspend requirements under GAAP for loan modifications to borrowers affected by COVID-19 that would otherwise be characterized as TDRs and suspend any determination related thereto if (i) the loan modification is made between March 1, 2020 and the earlier of December 31, 2020 or 60 days after the end of the coronavirus emergency declaration and (ii) the applicable loan was not more than 30 days past due as of December 31, 2019. On April 7, 2020, federal bank regulators issued a joint interagency statement that allows lenders to conclude that a borrower is not experiencing financial difficulty if short-term (e.g., six months or less) modifications are made in response to the COVID-19 pandemic, such as payment deferrals, fee waivers, extensions of repayment terms, or other delays in payment that are insignificant related to loans in which the borrower is less than 30 days past due on its contractual payments at the time a modification program is implemented. The CAA, signed into law on December 27, 2020, extends the applicable period to include modification to loans held by financial institutions executed between March 1, 2020 and the earlier of (i) January 1, 2022, or (ii) 60 days after the date of termination of the COVID-19 national emergency. For COVID-19 related loan modifications in the form of payment deferrals, the delinquency status will not advance and loans that were accruing at the time that the relief is provided will generally not be placed on nonaccrual status during the deferral period. Interest income will continue to be recognized over the contractual life of the loan. However, the Company, through its credit portfolio management activities, continued to monitor facts and circumstances associated with the underlying credit quality of loans modified under the provisions of the CARES Act in an effort to identify any loans where the accrual of interest during the modification period is no longer appropriate. In such cases, the Company ceases the accrual of interest and all previously accrued and uncollected interest is promptly reversed against current period interest income. At December 31, 2021, there were no COVID-19 loan modifications within their modification period under Section 4013 of the CARES Act and no loans were in-process for potential modification. As of December 31, 2020, 52 loans with an aggregate amortized cost of $79.5 million, or 0.56% of total loans held for investment, remained under modification due to the COVID-19 pandemic hardship under the CARES Act. Purchased Credit Deteriorated Loans Following the adoption of ASC 326 on January 1, 2020, the Company analyzed acquired loans for more-than-insignificant deterioration in credit quality since their origination. Such loans are classified as purchased credit deteriorated loans. Please see Note 1 - Description of Business and Summary of Significant Accounting Policies for more information concerning the accounting for PCD loans. The Company had no such loans at the adoption of ASC 326 on January 1, 2020. Acquired loans classified as PCD are recorded at an initial amortized cost, which is comprised of the purchase price of the loans (or initial fair value) and the initial ACL determined for the loans, which is added to the purchase price, as well as any resulting discount or premium related to factors other than credit. The Company accounts for interest income on PCD loans using the interest method, whereby any purchase discounts or premiums are accreted or amortized into interest income as an adjustment of the loan’s yield. Subsequent to acquisition, the ACL for PCD loans is measured in accordance with the Company’s ACL methodology. Please also see Note 5 - Allowance for Credit Losses for more information concerning the Company’s ACL methodology. The following table reconciles the par value, or initial amortized cost, of PCD loans acquired in the Opus acquisition as of the date of the acquisition with the purchase price (or ini

Provision for Loan and Lease Losses [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses Prior to the Company’s adoption of ASC 326 on January 1, 2020, the Company maintained an ALLL in accordance with ASC 310 and ASC 450 that represented an allowance for loan and lease losses for individually evaluated loans that were identified as impaired, as well as estimated probable incurred losses inherent in the remainder of the loan portfolio. The ALLL was prepared using the information provided by the Company’s credit review process, including internal risk grades for each loan, together with data from peer institutions and economic information gathered from published sources. The loan portfolio was segmented into groups of loans with similar risk characteristics. Each segment possessing 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. An estimated loss rate calculated using the Company’s historical loss rates, adjusted for current portfolio trends, economic conditions, and other relevant internal and external factors, was applied to each loan in each segment of the loan portfolio. The Company’s base ALLL factors were determined by management using the Bank’s annualized actual historical net charge-off data over a full credit cycle with an approximate average loss emergence period of 1 year to 1.6 years. Potential adjustments to those base factors were made for relevant internal and external factors. Those factors included: • Changes in lending policies and procedures, including underwriting standards and collection, charge-offs and recovery practices; • Changes in the nature and volume of the loan portfolio, including new types of lending; • Changes in the experience, ability, and depth of lending management and other relevant staff that may have an impact on our loan portfolio; • Changes in the volume and severity of adversely classified or graded loans; • Changes in the quality of our loan review system and the management oversight; • The existence and effect of any concentrations of credit and changes in the level of such concentrations; • Changes in national, regional, and local economic conditions, including trends in real estate values and the interest rate environment; • Changes in the value of the underlying collateral for collateral-dependent loans; and • The effect of external factors, such as competition, legal developments, and regulatory requirements on the level of estimated credit losses in our current loan portfolio. For loans with risk grades of watch or worse, progressively higher estimated loss rates were applied based on migration analysis of risk grading and net charge-offs. Effective January 1, 2020, the Company maintains an ACL for loans and unfunded loan commitments in accordance with ASC 326 - Financial Instruments - Credit Losses . 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 lifetime expected credit losses, given the facts and circumstances associated with a particular loan or group of loans with similar risk characteristics. Determining the ACL involves the use of significant management judgement and estimates, which are subject to change based on management’s ongoing assessment of the credit quality of the loan portfolio and changes in economic forecasts used in the model. The Company uses a discounted cash flow model when determining estimates for the ACL for commercial real estate loans and commercial loans, which comprise 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 sufficiently 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 loan commitments. These components consist of: (i) the estimated probability of default (“PD”), (ii) the estimated loss given default (“LGD”), 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 in 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 an 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 expected 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 or discounts, and deferred fees and costs associated with an originated 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 expected to be collected. The ACL for credit facilities is determined by discounting estimates for cash flows not expected to be collected. Probability of Default The PD for investor loans secured by real estate 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 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. This model incorporates assumptions for PD at a loan’s maturity. Significant loan and property level attributes include: loan-to-value ratios, debt service coverage, loan size, loan vintage, and property types. The PD for business loans is based on an internally developed PD rating scale that assigns PDs based on the Company’s internal risk grade 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 the Company’s business profile. As credit risk grades change for these loans, the PD assigned to them also changes. As with investor loans secured by real estate, the PD for business loans secured by real estate and 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 for loans in the Company’s loan portfolio, such as: loan-to-value ratios, estimated time to resolution, property size, and current and estimated future market price changes for underlying collateral. The LGD is highly dependent upon estimated 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 index for CRE pricing, 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 segment, 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 is 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. Economic Forecasts 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 a loan. The Company uses economic scenarios from an independent third-party, Moody’s Analytics. 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 forecast 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 scenarios chosen for the model, the extent to which more than one scenario is used, and 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 chosen, as well as the assumptions within those scenarios, and whether to use a probability-weighted multiple scenario approach, can vary from one period to the next based on changes in current and expected economic conditions, and due to the occurrence of specific events such as the ongoing COVID-19 pandemic. The Company recognizes the non-linearity of credit losses relative to economic performance and thus the Company believes consideration of and, if appropriate under the circumstances, use of multiple probability-weighted economic scenarios is appropriate in estimating credit losses over the forecast period. This approach 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 assigning reasonable probability weightings to them, some of the uncertainty associated with a single scenario approach, the Company believes, is mitigated. As of December 31, 2021, the Company’s ACL model used three probability-weighted forecast 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%. These economic scenarios include the current and estimated future impact associated with the ongoing COVID-19 pandemic. The Company evaluated the weightings of each economic scenario in the current period with the assistance of Moody's Analytics, and determined the current weightings of 40% for the base-case scenario, and 30% for each of the upside and downside scenarios appropriately reflect the likelihood of outcomes for each scenario given the current economic environment. The use of three probability-weighted scenarios at December 31, 2021 is consistent with the approach used in the Company’s ACL model at December 31, 2020. The Company, with the assistance of Moody’s Analytics, currently forecasts PDs and LGDs based on economic scenarios over a two-year period, which we believe is a reasonable and supportable period. Beyond this point, PDs and LGDs revert to historical 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 from each loan the Company does not expect to collect. The Company derives the economic forecasts it uses in its ACL model from Moody's Analytics that has a large team of economists, database managers, and operational engineers with a history of producing monthly economic forecasts. 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 December 31, 2021, the Company’s ACL model incorporated the following assumptions for key economic variables in the base-case, upside, and downside scenarios: Base-case Scenario: • U.S. unemployment declines to 3.5% through the end of 2022 and holds relatively constant at approximately 3.5% throughout 2023. • U.S. real GDP decelerates throughout 2022 from approximately 5.4% to approximately 2.7% by the end of 2022. U.S. real GDP growth decelerate from 3.1% from the beginning of 2023 to 2.9% towards the end of 2023. • CRE index growth accelerates in 2022 from 0.4% at the beginning of the year to approximately 11% by the end of 2022. Growth in the CRE index then decelerates from approximately 9% to 8% in 2023. Upside Scenario: • U.S. unemployment rate declines to 3% through the end of 2022 and holds relatively constant at approximately 3% throughout 2023. • U.S. real GDP decelerates throughout 2022 from approximately 9.3% to approximately 4.4% by the end of 2022. U.S. real GDP experiences growth within a range of 1.2% to 1.9% throughout 2023. • CRE index growth accelerates in 2022 from 1.9% at the beginning of the year to approximately 15% by the end of 2022. Growth in the CRE index then decelerates from approximately 12% to 8% in 2023. Downside Scenario: • U.S. unemployment rate increases to 8.7% through the end of 2022 and declines moderately to approximately 7.1% by the end of 2023. • U.S. real GDP experiences decelerating declines in the first three quarters of 2022, from -4.0% to -1.9% before returning to growth of 0.3% in the fourth quarter of 2022. U.S. real GDP experiences accelerating growth throughout 2023 of approximately 1.0% to 4.5%. • CRE index experiences accelerating declines through the third quarter of 2022 of -3.5% to -19.5%. The CRE index then experiences decelerating declines through the second quarter of 2023 from approximately -11% to -4%. The CRE index returns to growth in the second half of 2023. Qualitative Adjustments The Company recognizes that historical information used as the basis for determining future expected credit losses may not always, by itself, 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 backtesting, 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 December 31, 2021, qualitative adjustments included in the ACL totaled $4.0 million. These adjustments primarily relate to continued uncertainty concerning the strength of the economic recovery and how it may impact certain classes of loans in the loan portfolio. Management determined through additional review that the uneven recovery as well as labor shortages, continued supply chain disruptions and inflationary pressures may not be fully reflected in the quantitative component of the ACL for the SBA real estate secured, construction, and franchise classes of the loan portfolio and as such a qualitative adjustment has been assigned. 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. The following tables provide the allocation of the ACL for loans held for investment as well as the activity in the ACL attributed to various segments in the loan portfolio as of, and for the periods indicated: For the Year Ended December 31, 2021 (Dollars in thousands) Beginning ACL Balance Charge-offs Recoveries Provision for Credit Losses Ending Investor loans secured by real estate CRE non-owner-occupied $ 49,176 $ (154) $ 78 $ (11,720) $ 37,380 Multifamily 62,534 — — (7,325) 55,209 Construction and land 12,435 — — (7,224) 5,211 SBA secured by real estate 5,159 (424) 3 (1,537) 3,201 Business loans secured by real estate CRE owner-occupied 50,517 — 56 (20,998) 29,575 Franchise real estate secured 11,451 — — (3,466) 7,985 SBA secured by real estate 6,567 (98) 130 (1,733) 4,866 Commercial loans Commercial and industrial 46,964 (5,384) 4,720 (8,164) 38,136 Franchise non-real estate secured 20,525 (2,554) 405 (3,292) 15,084 SBA non-real estate secured 995 — 21 (451) 565 Retail loans Single family residential 1,204 — 3 (952) 255 Consumer loans 491 (2) 3 (207) 285 Totals $ 268,018 $ (8,616) $ 5,419 $ (67,069) $ 197,752 For the Year Ended December 31, 2020 (Dollars in thousands) Beginning ACL Balance (1) Adoption of ASC 326 Initial ACL Recorded for PCD Loans Charge-offs Recoveries Provision for Credit Losses Ending Investor loans secured by real estate CRE non-owner-occupied $ 1,899 $ 8,423 $ 3,025 $ (839) $ 44 $ 36,624 $ 49,176 Multifamily 729 9,174 8,710 — — 43,921 62,534 Construction and land 4,484 (124) 2,051 (539) — 6,563 12,435 SBA secured by real estate 1,915 (1,401) — (705) 34 5,316 5,159 Business loans secured by real estate CRE owner-occupied 2,781 20,166 3,766 (1,739) 59 25,484 50,517 Franchise real estate secured 592 5,199 — (932) — 6,592 11,451 SBA secured by real estate 2,119 2,207 235 (338) 147 2,197 6,567 Commercial loans Commercial and industrial 13,857 87 2,325 (6,891) 1,818 35,768 46,964 Franchise non-real estate secured 5,816 9,214 — (6,731) 866 11,360 20,525 SBA non-real estate secured 445 218 924 (899) 14 293 995 Retail loans Single family residential 655 541 206 (106) 2 (94) 1,204 Consumer loans 406 1,982 — (139) 4 (1,762) 491 Totals $ 35,698 $ 55,686 $ 21,242 $ (19,858) $ 2,988 $ 172,262 $ 268,018 ______________________________ (1) Beginning ACL balance represents the ALLL accounted for under ASC 450 and ASC 310, which is reflective of probable incurred losses as of the balance sheet date.

The provision recapture for the year ended December 31, 2021 is reflective of improved economic forecasts used in the Company’s ACL model, including a more favorable outlook for real estate prices and commercial vacancy rates. A favorable asset quality profile of the loan portfolio also contributed to the provision recapture and was partially offset by increases in loans held for investment during 2021. For the year ended December 31, 2020, the ACL for loans held for investment increased $232.3 million. The increase in the ACL was attributable to $172.3 million in provisions for credit losses, the establishment of $21.2 million in net ACL for PCD loans acquired in the Opus acquisition, and a $55.7 million adjustment to the ACL associated with the Company’s January 1, 2020 adoption of ASC 326, which was recorded through a cumulative effect adjustment to retained earnings. These increases were partially offset by net charge-offs of $16.9 million recorded during 2020. The provision for credit losses in 2020 is inclusive of $75.9 million related to the initial ACL required for the acquisition of non-PCD loans in the Opus acquisition. Under ASC 326, the Company is required to record an ACL for estimates of lifetime credit losses on non-PCD loans through a charge to provision for credit losses at the time of acquisition. However, the initial ACL for PCD loans is established through an adjustment to the loan’s purchase price (or initial fair value). Excluding the impact of the Opus acquisition, the provision for credit losses was $96.4 million for the year ended December 31, 2020 which was reflective of unfavorable economic forecasts in the Company’s ACL model, driven by the onset of the COVID-19 pandemic during 2020.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets At December 31, 2021, the Company had goodwill of $901.3 million. In June 2020, the Company acquired Opus, which resulted in the recognition of approximately $93.0 million in goodwill assets including post-acquisition measurement period purchase accounting adjustments totaling $146,000. These adjustments largely relate to the finalization of the short-year Opus tax returns within one year after the closing date of the acquisition, and resulted from additional information becoming available or finalized during that period about facts or circumstances that existed as of the acquisition date. During the year ended December 31, 2021 the Company recorded adjustments associated with the acquisition of Opus resulting in an increase to goodwill in the amount of $2.7 million. Adjustments to goodwill associated with the acquisition of Opus resulted in a decrease of $2.6 million to goodwill during the year ended December 31, 2020. The Company’s analysis of the fair value of assets acquired and liabilities assumed in the Opus acquisition was finalized during the second quarter of 2021. The following table presents changes in the carrying value of goodwill for the years ended December 31: (Dollars in thousands) 2021 2020 Balance, beginning of year $ 898,569 $ 808,322 Goodwill acquired during the year — 92,844 Purchase accounting adjustments 2,743 (2,597) Balance, end of year $ 901,312 $ 898,569 Accumulated impairment losses at end of year $ — $ — The Company’s policy is to assess goodwill for impairment on an annual basis during the fourth quarter of each year, and more frequently if events or circumstances lead management to believe the value of goodwill may be impaired. The Company performed a qualitative assessment of goodwill in accordance with ASC 350-20, Intangibles - Goodwill and Other - Goodwill during the fourth quarter of 2021, and determined goodwill was not impaired. During the fourth quarter of 2020, and in accordance with ASC 350-20, the Company made an unconditional election to forego a qualitative assessment of goodwill and proceed directly to the quantitative assessment of goodwill. The Company’s quantitative assessment of goodwill in the fourth quarter of 2020 consisted of a market approach as well as a discounted cash flow approach, both of which were given equal weighting in the analysis. The results of that analysis indicated the estimated fair value of the Company exceeded its carrying value and that the value of goodwill assets could be supported and there was no goodwill impairment as of December 31, 2020. The Company made the unconditional election to proceed directly to a quantitative assessment of goodwill in 2020 largely due to the volatility experienced in the Company’s stock price and weakened economic conditions stemming from the onset of the COVID-19 pandemic. At December 31, 2021, the Company had other intangible assets of $69.6 million, consisting of $66.9 million in core deposit intangibles and $2.7 million in customer relationship intangibles. The Company had no additions to other intangible assets during 2021. At December 31, 2020, the Company had other intangible assets of $85.5 million, consisting of $82.5 million in core deposit intangibles and $3.0 million in customer relationship intangibles. The Company had $19.3 million of additions to other intangible assets during 2020, consisting of $16.1 million of core deposit intangible assets and $3.2 million of customer relationship intangibles, both the result of the Opus acquisition. The following table summarizes the changes in the balances of core deposit and customer relationship intangible assets, and the related accumulated amortization for the years ended December 31: (Dollars in thousands) 2021 2020 2019 Gross balance of intangible assets: Balance, beginning of year $ 145,212 $ 125,945 $ 125,945 Additions due to acquisitions — 19,267 — Balance, end of year 145,212 145,212 125,945 Accumulated amortization: Balance, beginning of year (59,705) (42,633) (25,389) Amortization (15,936) (17,072) (17,244) Balance, end of year (75,641) (59,705) (42,633) Net intangible assets, end of year $ 69,571 $ 85,507 $ 83,312 The Company amortizes the core deposit and customer relationship intangibles based on the projected useful lives of the related deposits in the case of core deposit intangibles, and over the projected useful lives of the related client relationships in the case of customer relationship intangibles, typically ranging from six

Federal Home Loan Banks [Abstract]
Investments in Qualified Affordable Housing Partnerships	Investments in Qualified Affordable Housing Partnerships The Company invests in certain affordable housing projects in the form of ownership interests in limited partnerships or limited liability companies that qualify for CRA credit and generate low-income housing tax credits (“LIHTC”) and other tax benefits for the Company. The Company records its investments in qualified affordable housing partnerships using either the proportional amortization method, if certain criteria are met, or the cost method. Under the proportional amortization method, the Company amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits that are allocated to the Company over the period of the investment. The net benefits of these investments, which are comprised of tax credits and operating loss tax benefits, net of investment amortization, are recognized in the income statement as a component of income tax expense. At December 31, 2021 and 2020 the carrying value of these investments was $84.0 million and $86.8 million, respectively. For certain of the Company’s investments in qualified affordable housing partnerships that do not qualify for the application of the proportional amortization method, the Company applies the cost method. Under the cost method, the Company amortizes the initial cost of the investment as noninterest expense equally over the expected time period in which tax credits and other tax benefits will be received. Tax credits and other tax benefits on these investments are recognized as a component of income tax expense. At December 31, 2021 and 2020 the carrying value of these investments was $2.0 million and $3.0 million, respectively. The Company’s net investment in qualified affordable housing projects that generate LIHTC and other tax benefits at December 31, 2021 and 2020 was $86.0 million and $89.8 million, respectively, and is recorded in other assets in the consolidated statement of financial condition. The total unfunded commitments related to the investments in qualified affordable housing partnerships totaled $17.2 million and $18.1 million at December 31, 2021 and 2020, respectively, and were recorded in accrued expenses and other liabilities. As of December 31, 2021, the Company’s unfunded affordable housing partnerships commitments were estimated to be paid as follows: (Dollars in thousands) Amount Year Ending December 31, 2022 $ 3,871 2023 7,707 2024 2,999 2025 266 2026 350 Thereafter 2,036 Total unfunded commitments $ 17,229 The following table presents tax credits and other tax benefits generated by operating losses from qualified affordable housing projects as well as amortization expense associated with these investments for the years ended December 31, 2021, 2020, and 2019.

Variable Interest Entities

Variable Interest Entities	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities The Company is involved with VIEs through its loan securitization activities, affordable housing investments that qualify for the low-income housing tax credit, and trust subsidiaries, which have issued trust preferred securities. The Company has determined that its interests in these entities meet the definition of variable interests. As of December 31, 2021 and December 31, 2020, the Company determined it was not the primary beneficiary of the VIEs and did not consolidate its interests in VIEs. The following table provides a summary of the carrying amount of assets and liabilities in the Company’s consolidated statements of financial condition and maximum loss exposures as of December 31, 2021 and December 31, 2020 that relate to variable interests in non-consolidated VIEs. December 31, 2021 December 31, 2020 (Dollars in thousands) Maximum Loss Assets Liabilities Maximum Loss Assets Liabilities Multifamily loan securitization: Investment securities (1) $ 81,103 $ 81,103 $ — $ 100,927 $ 100,927 $ — Reimbursement obligation (2) 50,901 — 338 50,901 — 448 Affordable housing partnership: Other investments (3) 68,765 85,994 — 71,681 89,759 — Unfunded equity commitments (2) — — 17,229 — — 18,078 Total $ 200,769 $ 167,097 $ 17,567 $ 223,509 $ 190,686 $ 18,526 ______________________________ (1) Included in investment securities available-for-sale on the consolidated statement of financial condition. (2) Included in accrued expenses and other liabilities on the consolidated statement of financial condition. (3) Included in other assets on the consolidated statement of financial condition. . Multifamily loan securitization With respect to the securitization transaction with Freddie Mac discussed in Note 4 - Loans Held for Investment , the Company’s variable interests reside with the purchase of the underlying Freddie Mac-issued guaranteed, structured pass-through certificates that were held as investment securities available-for-sale at fair value as of December 31, 2021. Additionally, the Company has variable interests through a reimbursement agreement executed by Freddie Mac that obligates the Company to reimburse Freddie Mac for any defaulted contractual principal and interest payments identified after the ultimate resolution of the defaulted loans. Such reimbursement obligations are not to exceed 10% of the original principal amount of the loans comprising the securitization pool. As part of the securitization transaction, the Company released all servicing obligations and rights to Freddie Mac who was designated as the Master Servicer. In its capacity as Master Servicer, Freddie Mac can terminate the Company’s role as sub-servicer and direct such responsibilities accordingly. In evaluating our variable interests and continuing involvement in the VIE, we determined that we do not have the power to make significant decisions or direct the activities that most significantly impact the economic performance of the VIE’s assets and liabilities. As sub-servicer of the loans, the Company does not have the authority to make significant decisions that influence the value of the VIE’s net assets and, therefore, the Company is not the primary beneficiary of the VIE. As a result, we determined that the VIE associated with the multifamily securitization should not be included in the consolidated financial statements of the Company. We believe that our maximum exposure to loss as a result of our involvement with the VIE associated with the securitization is the carrying value of the investment securities issued by Freddie Mac and purchased by the Company. Additionally, our maximum exposure to loss under the reimbursement agreement executed with Freddie Mac is 10% of the original principal amount of the loans comprising the securitization pool, or $50.9 million. Based upon our analysis of quantitative and qualitative data over the underlying loans included in the securitization pool, as of December 31, 2021 and December 31, 2020, our reserve for estimated losses with respect to the reimbursement obligation was $338,000 and $448,000, respectively. Investments in qualified affordable housing partnerships The Company has variable interests through its affordable housing partnership investments. These investments are fundamentally designed to provide a return through the generation of income tax credits. The Company has evaluated its involvement with the low-income housing projects and determined it does not have significant influence or decision making capabilities to manage the projects, and therefore, is not the primary beneficiary, and does not consolidate these interests. The Company’s maximum exposure to loss, exclusive of any potential realization of tax credits, is equal to the commitments invested, adjusted for amortization. The amount of unfunded commitments was included in the investments recognized as assets with a corresponding liability. The table above summarizes the amount of tax credit investments held as assets, the amount of unfunded commitments held as liabilities, and the maximum exposure to loss as of December 31, 2021 and December 31, 2020, respectively. Trust preferred securities 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, acquired through bank acquisitions, under the equity method whereby the subsidiary’s net earnings are recognized in the Company’s consolidated statements of income and the investment in these entities is included in other assets in the Company’s consolidated statements of financial condition. The Corporation is not allowed to consolidate the capital trusts as they have been formed for the sole purpose of issuing trust preferred securities, from which the proceeds were invested in the Company’s junior subordinated debt securities and reflected in our consolidated statements of financial condition as subordinated debentures with the corresponding interest distributions reflected as interest expense in the consolidated statements of income. The capital securities are subject to mandatory redemption, in whole or in part, upon repayment of the subordinated debt, and qualified as Tier 2 capital. In July 2021, the Company redeemed $5.2 million junior subordinated debt securities associated with Heritage Oaks Capital Trust II and $5.2 million junior subordinated debt securities associated with Santa Lucia Bancorp (CA) Capital Trust. Subsequent to the redemptions, Heritage Oaks Capital Trust II and Santa Lucia Bancorp (CA) Capital Trust were dissolved. See Note 13 - Subordinated Debentures for additional information.

Debt Disclosure [Abstract]
Subordinated Debentures	Subordinated Debentures As of December 31, 2021, the Company had three subordinated notes with an aggregate carrying value of $330.6 million and a weighted interest rate of 5.33%, compared to $501.5 million with a weighted interest rate of 5.38% at December 31, 2020. The decrease of $170.9 million is primarily due to the redemption of $170.4 million in subordinated debentures. In August 2014, the Corporation issued $60.0 million in aggregate principal amount of 5.75% Subordinated Notes Due 2024 (the “Notes I”) in a private placement transaction to institutional accredited investors (the “Private Placement”). The Notes I bear interest at an annual fixed rate of 5.75%, with the first interest payment on the Notes made on March 3, 2015, and interest payable semiannually each March 3 and September 3 through September 3, 2024. At December 31, 2021, the carrying value of the Notes was $59.7 million, net of unamortized debt issuance costs of $329,000. The Notes can only be redeemed, in whole or in part, prior to the maturity date if the notes do not constitute Tier 2 Capital (for purposes of capital adequacy guidelines of the Board of Governors of the Federal Reserve). Principal and interest are due upon early redemption. As of December 31, 2021, 40% of the Notes I qualify as Tier 2 Capital as the remaining maturity is less than four years pursuant to regulatory capital rule. In May 2019, the Corporation issued $125.0 million in aggregate principal amount of 4.875% Fixed-to-Floating Rate Subordinated Notes due May 15, 2029 (the “Notes II”), at a public offering price equal to 100% of the aggregate principal amount of the Notes II. The Corporation may redeem the Notes II on or after May 15, 2024. From and including the issue date, but excluding May 15, 2024, the Notes II will bear interest at an initial fixed rate of 4.875% per annum, payable semi-annually. From and including May 15, 2024, but excluding the maturity date or the date of earlier redemption, the Notes II will bear interest at a floating rate equal to the then-current three-month LIBOR plus a spread of 2.50% per annum, payable quarterly in arrears. Principal and interest are due upon early redemption at any time, including prior to May 15, 2024 at our option, in whole but not in part, under the occurrence of special events defined within the trust indenture. At December 31, 2021, the Notes II qualify as Tier 2 Capital. At December 31, 2021, the carrying value of the Notes II was $123.1 million, net of unamortized debt issuance cost of $1.9 million. In June 2020, the Corporation issued $150.0 million aggregate principal amount of its 5.375% fixed-to-floating rate subordinated notes due 2030 (the “Notes III”) at a public offering price equal to 100% of the aggregate principal amount of the Notes III. The Corporation may redeem the Notes III on or after June 14, 2025. Interest on the Notes III accrue at a rate equal to 5.375% per annum from and including June 15, 2020 to, but excluding, June 15, 2025, payable semiannually in arrears. From and including June 15, 2025 to, but excluding, June 15, 2030 or the earlier redemption date, interest will accrue at a floating rate per annum equal to a benchmark rate, which is expected to be Three-Month Term SOFR, plus a spread of 517 basis points, payable quarterly in arrears. Principal and interest are due upon early redemption at any time, including prior to June 15, 2025 at our option, in whole but not in part, under the occurrence of special events defined within the trust indenture. At December 31, 2021, the Notes III qualified as Tier 2 capital. At December 31, 2021, the carrying value of the Notes III was $147.8 million, net of unamortized debt issuance cost of $2.2 million. On April 15, 2021, the Company redeemed the subordinated notes totaling $25.0 million that the Company assumed as part of the acquisition of Plaza Bancorp, Inc. in 2017. Prior to redemption, such subordinated notes carried a fixed interest rate of 7.125% and were scheduled to mature on June 26, 2025. These subordinated notes were called at 103% of the principal amount of the notes, plus accrued and unpaid interest, for an aggregate amount of $25.8 million. The Company recorded a loss on early debt extinguishment of $647,000 after considering a $103,000 fair value mark related to purchase accounting adjustments. On July 1, 2021, the Company redeemed $135.0 million subordinated notes acquired from Opus and $5.2 million junior subordinated debt associated with Heritage Oaks Capital Trust II. Prior to redemption, the subordinated notes and junior subordinated debt securities carried an interest rate of 5.50% and 1.92%, respectively. On July 7, 2021, the Company redeemed $5.2 million junior subordinated debt associated with Santa Lucia Bancorp (CA) Capital Trust. Prior to redemption, the junior subordinated debt securities carried an interest rate of 1.66%. The subordinated notes and junior subordinated debt were redeemed at par, plus accrued and unpaid interest, for an aggregate amount of $149.2 million. The Company recorded a net gain on early debt extinguishment of $970,000 related to purchase accounting adjustments. Subsequent to the redemptions of these junior subordinated debt securities, the Company’s unconsolidated Delaware statutory trust subsidiaries, Heritage Oaks Capital Trust II and Santa Lucia Bancorp (CA) Capital Trust, that were used as business trusts for the purpose of issuing trust preferred securities to third party investors were dissolved. In connection with the Private Placement, the Corporation obtained ratings from Kroll Bond Rating Agency (“KBRA”). 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 June 2021 by KBRA. For regulatory capital purposes, the trust preferred securities are included in Tier 2 capital. The redemption of subordinated notes totaling $25.0 million during the second quarter of 2021 reduced the Company’s Tier 2 capital by approximately $20.0 million. The redemption of subordinated notes and trust preferred securities totaling $145.4 million during the third quarter of 2021 reduced the Company’s Tier 2 capital by approximately $146.0 million. Following these redemptions, the regulatory total capital ratios of the Company and the Bank continued to exceed regulatory minimums, inclusive of the fully phased-in capital conservation buffer.

The Company is permitted to carryback 2018 NOL of an acquired entity, Grandpoint, to its prior tax years, which have income tax rates ranging from 34% to 35%. As a result, the Company recorded an income tax benefit of $2.6 million attributable to the Grandpoint NOL carryback during the year ended December 31, 2020. Deferred tax assets (liabilities) were comprised of the following temporary differences between the financial statement carrying amounts and the tax basis of assets at December 31: (Dollars in thousands) 2021 2020 Deferred tax assets: Accrued expenses $ 3,681 $ 1,307 Net operating loss 5,681 6,614 Allowance for credit losses, net of bad debt charge-offs 64,628 85,700 Deferred compensation 3,338 3,489 State taxes 6,834 4,395 Loan net discounts 21,980 32,484 Stock-based compensation 4,030 4,618 Operating lease liabilities 20,708 24,463 Unrealized loss on available-for-sale securities 3,156 — Federal and state credit carryovers 2,242 3,750 Other — 1,782 Total deferred tax assets 136,278 168,602 Deferred tax liabilities: Operating lease right-of-use assets $ (18,272) $ (21,756) Deferred FDIC gain (69) (108) Core deposit intangibles (17,676) (21,828) Loan origination costs (7,547) (5,176) Depreciation (4,897) (6,551) Unrealized gain on available-for-sale securities — (24,127) Other (473) — Total deferred tax liabilities (48,934) (79,546) Valuation allowance — — Net deferred tax assets $ 87,344 $ 89,056 The Company accounts for income taxes by recognizing deferred tax assets and liabilities based upon temporary differences between the amounts for financial reporting purposes and the tax basis of its assets and liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion, or all, of the deferred tax asset will not be realized. In assessing the realization of deferred tax assets, management evaluates both positive and negative evidence, including the existence of any cumulative losses in the current year and the prior two years, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions. This analysis is updated quarterly and adjusted as necessary. Based on the analysis, the Company has determined that a valuation allowance for deferred tax assets was not required as of December 31, 2021 and December 31, 2020. Section 382 of the Internal Revenue Code imposes limitations on a corporation’s ability to use any net unrealized built in losses and other tax attributes, such as net operating loss and tax credit carryforwards, when it undergoes a 50% ownership change over a designated testing period. The Company has a Section 382 limited net operating loss carry-forward of approximately $24.7 million for federal income tax purposes, which is scheduled to expire at various dates from 2026 to 2032. The Company also has a Section 382 limited net operating loss carry forward of approximately $6.6 million for California franchise tax purposes, which is scheduled to expire at various dates from 2029 to 2033 with the carryover period extension from California Assembly Bill 85 (“A.B. 85”) and Senate Bill 113 (“S.B. 113”). On June 29, 2020, A.B. 85 was signed into law, and among other changes, A.B. 85 suspends the use of the California NOL for the 2020, 2021, and 2022 tax years. On February 9, 2022, S.B. 113 was signed into law, and among other changes, S.B. 113 reinstates the California NOL deductions for tax years beginning in 2022, in effect shortening the suspension period from A.B. 85 by one year for NOL deductions. For NOL incurred in tax years before 2020 for which a deduction is denied, the carryover period is extended by two years. In addition, the Company has a Section 382 limited tax credit carryforward of $1.8 million, which is scheduled to expire by 2040. The Company is expected to fully utilize the federal and California net operating loss carryforward before it expires with the application of the Section 382 annual limitation. The Company and its subsidiaries are subject to U.S. Federal income tax as well as income and franchise tax in multiple state jurisdictions. The statute of limitations related to the consolidated Federal income tax returns is closed for all tax years up to and including 2017. The expirations of the statutes of limitations related to the various state income and franchise tax returns vary by state. The Company is currently not under examination in any taxing jurisdiction. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31 is as follows: (Dollars in thousands) 2021 2020 Balance at January 1, $ 255 $ 2,906 Increases based on tax positions related to prior years 1,437 233 Decreases related to settlements with taxing authorities (233) — Decreases related to lapse of statute of limitation (22) (2,884) Balance at December 31, $ 1,437 $ 255 The total amount of unrecognized tax benefits was $1.4 million and $255,000 at December 31, 2021 and 2020, respectively, and is primarily comprised of unrecognized tax benefits related to the Opus acquisition in 2020. The total amount of tax benefits that, if recognized, would favorably impact the effective tax rate was $563,000 and $184,000 at December 31, 2021 and 2020, respectively. The Company does not believe that the unrecognized tax benefits will change significantly within the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company had accrued for $31,000 and $22,000 of such interest at December 31, 2021 and 2020, respectively. No amounts for penalties were accrued at December 31, 2021 and 2020.

Commitments and Contingencies Disclosure [Abstract]
Off-Balance Sheet Arrangements, Commitments, and Contingencies	Off-Balance Sheet Arrangements, Commitments, and Contingencies Commitments to Extend Credit The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit in the form of originating loans or providing funds under existing lines or letters of credit. These commitments are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates and may require payment of a fee. Since many commitments are expected to expire, the total commitment amounts do not necessarily represent future cash requirements. Commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the accompanying consolidated statements of financial condition. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual or notional amount of those instruments. The Company controls credit risk of its commitments to fund loans through credit approvals, limits and monitoring procedures. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. The Company evaluates each customer for creditworthiness. The Company receives collateral to support commitments when deemed necessary. The most significant categories of collateral include real estate properties underlying mortgage loans, liens on personal property, and cash on deposit with the Bank. Standby letters of credit are conditional commitments issued by the Bank to guarantee the financial performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing or purchase arrangements. If a borrower defaults on its commitments subject to any letter of credit issued under these arrangements, the Bank would be required to meet the borrower's financial obligation but would seek repayment of that financial obligation from the borrower. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the customer. The following table presents a summary of the Company’s commitments to extend credit described below as of the dates indicated: For the Year Ended December 31, (Dollars in thousands) 2021 2020 Loan commitments to extend credit $ 2,464,656 $ 1,908,479 Standby letters of credit 43,255 38,771 Total $ 2,507,911 $ 1,947,250 The balance at December 31, 2021 is primarily composed of $1.94 billion of undisbursed commitments for C&I loans. The Company maintains an allowance for credit losses for off-balance sheet commitments to provide for commitments associated with undisbursed loan funds and unused lines of credit. The allowance for credit losses for off-balance sheet commitments was $27.3 million and $31.1 million at December 31, 2021 and 2020, respectively. The change in the allowance for credit losses for off-balance sheet commitments during the year ended December 31, 2021 was reflective of improving economic conditions and forecasts in the Company's ACL model relative to the prior year end, partially offset by increases in unfunded loan commitments during 2021. See Note 5 - Allowance for Credit Losses for additional information. Other Commitments The Company has commitments to invest in qualified affordable housing partnerships that qualify for CRA credit and generate LIHTC and other tax benefits as discussed in Note 9 — Investments in Qualified Affordable Housing Partnerships . As of December 31, 2021 and 2020, LIHTC commitments totaled $17.2 million and $18.1 million, respectively. Trust Custodial Asset Accounts The Company’s Pacific Premier Trust division holds certain assets in custodial capacity on behalf of our trust customers, which are not included in our consolidated financial statement of condition. The total trust custodial assets under custody was approximately $18.11 billion and $15.89 billion at December 31, 2021 and 2020, respectively. Legal Proceedings

Heritage Oaks Bancorp, Inc. 2005 Equity Based Compensation Plan (the “2005 Plan”). The 2005 Plan was acquired from Heritage Oaks Bancorp, Inc. on April 1, 2017. The 2005 Plan authorized the granting of Incentive Stock Options, Non-Qualified Stock Options, Stock Appreciation Rights, Restricted Stock Awards, Restricted Stock Units, and Performance Share Cash Only Awards. As of December 31, 2016, no further grants can be made from this plan; however, Pacific Premier assumed all unvested and unexercised awards. Pacific Premier Bancorp, Inc. 2012 Long-Term Incentive Plan (the “2012 Plan”) . The 2012 Plan was approved by the Corporation’s stockholders in May 2012. The 2012 Plan originally authorized the granting of Awards equal to 620,000 shares of the common stock of the Corporation for issuances to executives, key employees, officers, and directors. The 2012 Plan will be in effect for a period of ten years from May 30, 2012, the date the 2012 Plan was adopted. Awards granted under the 2012 Plan will be made at an exercise price equal to the fair market value of the stock on the date of grant.

The 2015 Plan authorized the granting of various types of share-based compensation awards to the employees and Board of Directors such as stock options, restricted stock awards, and restricted stock units. Under the 2015 Plan and following the Corporation’s assumption of the 2015 Plan, a maximum of 630,473 shares of the Corporation’s common stock at the date of acquisition were reserved and available to be issued. Shares issued under this plan, other than stock options and stock appreciation rights, were counted against the plan on a two shares for every one share actually issued basis. Awards that were canceled, expired, forfeited, fail to vest, or otherwise resulted in issued shares not being delivered to the grantee, were made available for the issuance of future share-based compensation awards.

Fair Value of Financial Instrum

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. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. 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 for certain instruments measured at fair value, as well as the general classification of these instruments pursuant to the valuation hierarchy. Investment securities – Investment securities are generally valued based upon quotes obtained from an independent third-party pricing service, which uses 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. Interest rate swaps – 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 Company also enters into interest rate swap contracts with institutional counterparties to hedge against certain fixed-rate loans. 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 incorporates credit value adjustments on derivatives to properly reflect the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. The Company has determined that the observable nature of the majority of inputs used in deriving the fair value of these derivative contracts fall within Level 2 of the fair value hierarchy, and the credit valuation adjustments are not significant to the overall valuation of its derivative financial instruments. As a result, the valuation of interest rate swaps is classified as Level 2 of the fair value hierarchy. Equity warrant assets – The Company acquired equity warrant assets as a result of the acquisition of Opus. Opus received equity warrant assets through its lending activities as part of loan origination fees. The warrants provide the Bank the right to purchase a specific number of equity shares of the underlying company’s equity at a certain price before expiration and contain net settlement terms qualifying as derivatives under ASC Topic 815. The fair value of equity warrant assets is determined using a Black-Scholes option pricing model and are classified as Level 3 of the fair value hierarchy due to the extent of unobservable inputs. The key assumptions used in determining the fair value include the exercise price of the warrants, valuation of the underlying entity's outstanding stock, expected term, risk-free interest rate, marketability discount for private company warrants, and price volatility. The following fair value hierarchy tables present information about the Company’s assets measured at fair value on a recurring basis at the dates indicated: At December 31, 2021 Fair Value Measurement Using (Dollars in thousands) Level 1 Level 2 Level 3 Securities at Financial assets Investment securities available-for-sale: U.S. Treasury $ — $ 57,866 $ — $ 57,866 Agency — 432,135 — 432,135 Corporate — 453,861 — 453,861 Municipal bonds — 1,089,913 — 1,089,913 Collateralized mortgage obligation — 676,643 — 676,643 Mortgage-backed securities — 1,563,446 — 1,563,446 Total securities available-for-sale $ — $ 4,273,864 $ — $ 4,273,864 Derivative assets: Interest rate swaps $ — $ 10,100 $ — $ 10,100 Equity warrants — — 1,889 1,889 Total derivative assets $ — $ 10,100 $ 1,889 $ 11,989 Financial liabilities Derivative liabilities $ — $ 5,263 $ — $ 5,263 At December 31, 2020 Fair Value Measurement Using (Dollars in thousands) Level 1 Level 2 Level 3 Securities at Financial assets Investment securities available-for-sale: U.S. Treasury $ — $ 32,533 $ — $ 32,533 Agency — 690,386 $ — 690,386 Corporate — 415,308 $ — 415,308 Municipal bonds — 1,446,019 — 1,446,019 Collateralized mortgage obligation — 513,366 — 513,366 Mortgage-backed securities — 833,503 — 833,503 Total securities available-for-sale $ — $ 3,931,115 $ — $ 3,931,115 Derivative assets: Interest rate swaps $ — $ 12,053 $ — $ 12,053 Equity warrants — — 1,914 1,914 Total derivative assets $ — $ 12,053 $ 1,914 $ 13,967 Financial liabilities Derivative liabilities $ — $ 12,066 $ — $ 12,066 The following table is a reconciliation of the fair value of the equity warrants that are classified as Level 3 and measured on a recurring basis as of: (Dollars in thousands) 2021 2020 Beginning Balance $ 1,914 $ 5,162 Change in fair value (1) (25) (41) Sales — (3,207) Ending balance $ 1,889 $ 1,914 ______________________________ (1) The changes in fair value are included in other income on the consolidated statement of income.

Individually evaluated loans are 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. The fair value of individually evaluated collateral dependent loans were determined using Level 3 assumptions, and represents individually evaluated loan 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 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 December 31, 2021, 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 reserves during the year ended December 31, 2021.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company’s restricted stock awards contain non-forfeitable rights to dividends and therefore are considered participating securities. The Company calculates basic and diluted earnings per common share 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: For the Year Ended December 31, (Dollars in thousands, except per share data) 2021 2020 2019 Basic Net income $ 339,889 $ 60,351 $ 159,718 Less: dividends and undistributed earnings allocated to participating securities (3,517) (798) (1,650) Net income allocated to common stockholders $ 336,372 $ 59,553 $ 158,068 Weighted average common shares outstanding 93,532,109 79,209,560 60,339,714 Basic earnings per common share $ 3.60 $ 0.75 $ 2.62 Diluted Net income allocated to common stockholders $ 336,372 $ 59,553 $ 158,068 Weighted average common shares outstanding 93,532,109 79,209,560 60,339,714 Dilutive effect of share-based compensation 480,028 287,513 352,567 Dilutive effect of stock warrants — 9,201 — Weighted average diluted common shares 94,012,137 79,506,274 60,692,281 Diluted earnings per common share $ 3.58 $ 0.75 $ 2.60

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company uses derivative instruments to manage its exposure to market risks, including interest rate risk, and to assist customers with their risk management objectives. The Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship, while other derivatives serve as economic hedges that do not qualify for hedge accounting. Derivatives Designated as Hedging Instruments Fair Value Hedges – The Company is exposed to changes in the fair value of fixed-rate assets due to changes in benchmark interest rates. During the third and fourth quarter of 2021, the Company entered into $300.0 million and $900.0 million in notional amount, respectively, of pay-fixed and receive-floating interest rate swaps associated with certain fixed rate loans, primarily commercial real estate loans, to manage its exposure to changes in fair value on these instruments attributable to changes in the designated USD-SOFR-COMPOUND benchmark interest rate. These interest rate swaps are designated as fair value hedges using the last-of-layer method. As a result, the Company receives variable-rate interest payments in exchange for making fixed-rate payments over the lives of the contracts without exchanging the notional amounts. The fair value of fair value hedges are recorded as components of other assets and other liabilities in the Company’s consolidated statements of financial condition. The gain or loss on these derivatives, as well as the offsetting loss or gain on the hedged items attributable to the hedged risk are recognized in interest income in the Company’s consolidated statements of income. At December 31, 2021, interest rate swaps with an aggregate notional amount of $1.20 billion were designated as fair value hedges. The following amounts were recorded on the consolidated statement of financial condition related to cumulative basis adjustment for fair value hedges as of the dates indicated: Line Item in the Statement of Financial Position in Which the Hedged Item is Included Carrying Amount of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets (Dollars in thousands) December 31, 2021 December 31, 2020 December 31, 2021 December 31, 2020 Loans held for investment (1) $ 1,194,702 $ — $ (5,298) $ — Total $ 1,194,702 $ — $ (5,298) $ — ______________________________ (1) These amounts were included in the amortized cost basis of closed portfolios used to designate hedging relationships in which the hedged item is the last layer expected to be remaining at the end of the hedging relationship. At December 31, 2021 , the amortized cost basis of the closed portfolios used in these hedging relationships was $3.61 billion; the cumulative basis adjustments associated with these hedging relationships was $5.3 million; and the amounts of the designated hedged items were $1.20 billion . Derivatives Not Designated as Hedging Instruments Interest Rate Swap Contracts – 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. The Company had over-the-counter derivative instruments and centrally-cleared derivative instruments with matched terms. 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 interest 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 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. 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 the 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. All interest rate swap agreements entered into by the Company are free-standing derivatives and are not designated as hedging instruments. Other Contracts – The Company’s credit derivatives result from entering into credit risk participation agreements (“RPAs”) with a counterparty bank (Opus) during the first quarter of 2020 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. As the result of the acquisition of Opus, the RPAs were terminated in the second quarter 2020. Equity Warrant Assets – The Company acquired equity warrant assets as a result of the acquisition of Opus. Opus received equity warrant assets through its lending activities, which were accounted for as loan origination fees. The warrants provide the Bank the right to purchase a specific number of equity shares of the underlying company’s equity at a certain price before expiration and contain net settlement terms qualifying as derivatives under ASC Topic 815. The Company no longer has loans associated with these borrowers. Changes in fair value are recognized as a component of noninterest income with a corresponding offset within other assets. The total fair value of the warrants held in private companies was $1.9 million in other assets as of December 31, 2021 and December 31, 2020. The two warrants expire on March 12, 2023 and July 28, 2025, respectively.

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. 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 the periods indicated are presented in the table below: Gross Amounts Not Offset in the Consolidated (Dollars in thousands) Gross Amounts Recognized in the Consolidated Balance Sheets Gross Amounts Offset in the Consolidated Balance Sheets Net Amounts Presented in the Consolidated Balance Sheets Financial Instruments (1) Cash Collateral (2) Net Amount December 31, 2021 Derivative assets: Interest rate swaps $ 10,100 $ — $ 10,100 $ — $ — $ 10,100 Total $ 10,100 $ — $ 10,100 $ — $ — $ 10,100 Financial liabilities: Interest rate swaps $ 5,263 $ — $ 5,263 $ (4,377) $ (886) $ — Total $ 5,263 $ — $ 5,263 $ (4,377) $ (886) $ — December 31, 2020 Derivative assets: Interest rate swaps $ 12,053 $ — $ 12,053 $ — $ — $ 12,053 Total $ 12,053 $ — $ 12,053 $ — $ — $ 12,053 Financial liabilities: Interest rate swaps $ 12,066 $ — $ 12,066 $ (6,140) $ (5,926) $ — Total $ 12,066 $ — $ 12,066 $ (6,140) $ (5,926) $ — (1) Represents the fair value of securities pledged with counterparty bank.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company accounts for revenue from contracts with customers in accordance with ASC 606, which requires revenue that is derived from a contract with a customer 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, such as a deposit account agreement, which can be canceled at any time, or a service provided to a customer at a point in time. These revenue streams are included in noninterest income. The Company’s principal source of revenue is interest income on loans, investment securities, and other interest earning assets, all of which are not within the scope of ASC 606 and are accounted for under other applicable GAAP. The remainder of the Company’s revenue is classified as noninterest income and is earned from a variety of sources, such as custodial and other fees, service charges, gains and losses, interchange income, and other income. The following table provides a summary of the Company’s noninterest income, segregated by revenue streams within and outside the scope of ASC 606 for the periods indicated: For the Year Ended December 31, 2021 2020 2019 (Dollars in thousands) Within Scope (1) Out-of-Scope (2) Within Scope (1) Out-of-Scope (2) Within Scope (1) Out-of-Scope (2) Noninterest income: Loan servicing income $ — $ 2,121 $ — $ 2,028 $ — $ 1,840 Service charges on deposit accounts 9,219 — 6,712 — 5,769 — Other service fee income 1,566 — 1,554 — 1,438 — Debit card interchange income 3,489 — 2,526 — 3,004 — Earnings on bank-owned life insurance — 11,299 — 7,160 — 3,486 Net gain from sales of loans — 4,428 — 8,609 — 6,642 Net gain from sales of investment securities — 16,906 — 13,882 — 8,571 Trust custodial account fees 38,176 — 16,653 — — — Escrow and exchange fees 7,286 — 2,663 — Other income 430 12,930 427 9,111 1,015 3,471 Total noninterest income $ 60,166 $ 47,684 $ 30,535 $ 40,790 $ 11,226 $ 24,010 ______________________________ (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 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. 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 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 and the Company satisfies it performance obligation through daily settlement through a payment network. Debit card interchange fees are typically received and recorded as revenue on a daily basis. Trust Custodial Account Fees Trust custodial account fee income is a revenue stream acquired in the Opus acquisition in June 2020 and is attributable to contracts executed with Pacific Premier Trust clients, largely to perform maintenance and custodial services for their alternative IRA investments as well as certain accounts that do not qualify as individual retirement accounts pursuant to the Internal Revenue Code. Typically, these fees are billed and collected on a quarterly basis and recognized commensurate with completion of the performance obligations required under the contracts. At December 31, 2021 and December 31, 2020, the Company had accrued fees receivable of approximately $13.1 million and $5.8 million, respectively, which are included in other assets in the consolidated statements of financial position. The balance of accrued fees receivable is net an allowance for credit losses for doubtful accounts of approximately $955,000 and $268,000 at December 31, 2021 and December 31, 2020, respectively. The allowance represents the Company’s estimate of credit losses on accrued fees receivable in accordance in ASC 326. Escrow and Exchange Fees Escrow and exchange fee income is a revenue stream associated with Commerce Escrow, which was acquired in the Opus acquisition in 2020. These fees relate to agreements with customers participating in escrow and exchange transactions associated with Section 1031 of the Internal Revenue Code. Escrow and exchange services include preparation of closing statements and custody of escrow funds. The fees are received from the sale proceeds of a relinquished property and are recognized as revenue upon closing of the escrow transaction, which is the final performance obligation. 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 of the related transaction or service provided. Other revenue streams that occur from time to time 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.

Leases [Abstract]
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. 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 December 31, 2021, all of the Company’s leases were classified as operating leases or short-term leases. Short-term leases are leases that have a term of 12 months or less at commencement. Liabilities to make future lease payments 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 the Company’s estimated incremental borrowing rate if the rate implicit in the lease is not readily determinable. Liabilities to make future lease payments on operating leases are 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. The Company recognizes expense for both operating leases and short-term leases on a straight-line basis. The Company’s lease expense is recorded in premises and occupancy expense in the consolidated statements of income. The following table presents the components of lease expense for the periods indicated: For the Year Ended December 31, (Dollars in thousands) 2021 2020 Operating leases $ 19,481 $ 18,065 Short-term leases 1,616 2,031 Total lease expense $ 21,097 $ 20,096 The Company assumed operating leases in the acquisition of Opus on June 1, 2020. The liabilities and the related right-of-use assets recorded for the assumption of these leases were approximately $43.3 million and $42.4 million, respectively. Right-of-use assets related to the Opus acquisition reflect unfavorable lease liability adjustments of approximately $900,000. Lease liabilities for the leases assumed from Opus were measured based on the net present value of remaining future lease payments on the date of acquisition, with consideration given for options to extend or renew each lease. Remaining future lease payments were discounted at the Company’s estimated incremental borrowing rate on the date of acquisition.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions Acquisition of Opus Effective as of June 1, 2020, the Corporation completed the acquisition of Opus, a California-chartered state bank headquartered in Irvine, California, pursuant to a definitive agreement dated as of January 31, 2020. At closing, Opus had $8.32 billion in total assets, $5.94 billion in gross loans, and $6.91 billion in total deposits and operated 46 banking offices located throughout California, Washington, Oregon, and Arizona. As a result of the Opus acquisition, the Corporation acquired specialty lines of business, including trust and escrow services. Prior to the Opus acquisition, PENSCO Trust Company LLC, a Colorado-chartered non-depository trust company (“PENSCO”), operated as an indirect, wholly-owned subsidiary of Opus and served as a custodian for self-directed IRAs, the funds of which account owners used for self-directed investments in various alternative asset classes. Immediately following the Opus acquisition, PENSCO merged with and into the Bank and operates its custodial business under the name of Pacific Premier Trust, as a division of the Bank. As of May 31, 2020, PENSCO had approximately $14.48 billion of custodial assets and approximately 44,000 client accounts. Prior to the Opus acquisition, Commerce Escrow operated as a division of Opus, offering commercial escrow services and facilitating tax-deferred commercial exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended. Following the acquisition of Opus, Commerce Escrow operates as a division of the Bank, which created synergies with the Company’s existing escrow deposit business. The acquisition of Opus expands the Company’s presence in major metropolitan markets with greater operational scale, diversifies business lines, banking products and services, as well as deposit base and clients by adding a new channel of stable, low-cost deposits and fee income from Opus’s trust and escrow businesses, improves revenue, and accelerates the Company’s ability to invest in technology solutions and increase efficiencies. Pursuant to the terms of the merger agreement, the consideration paid to Opus shareholders consisted of whole shares of the Corporation’s common stock and cash in lieu of fractional shares of the Corporation’s common stock. Upon consummation of the transaction, (i) each share of Opus common stock issued and outstanding immediately prior to the effective time of the acquisition was canceled and exchanged for the right to receive 0.900 shares of the Corporation’s common stock, with cash to be paid in lieu of fractional shares at a rate of $19.31 per share, and (ii) each share of Opus Series A non-cumulative, non-voting preferred stock issued and outstanding immediately prior to the effective time of the acquisition was converted into and canceled in exchange for the right to receive that number of shares of the Corporation’s common stock equal to the product of (X) the number of shares of Opus common stock into which such share of Opus preferred stock was convertible in connection with, and as a result of, the acquisition, and (Y) 0.900, in each case, plus cash in lieu of fractional shares of the Corporation’s common stock. The Corporation issued 34,407,403 shares, net of 165,136 shares for tax withholding from Opus equity award holders, of the Corporation’s common stock valued at $21.62 per share, which was the closing price of the Corporation’s common stock on May 29, 2020, the last trading day prior to the consummation of the acquisition, and paid cash in lieu of fractional shares. The Corporation assumed Opus’s warrants and options, which represented the issuance of up to approximately 406,778 and 9,538 additional shares of the Corporation’s common stock, valued at approximately $1.8 million and $46,000, respectively, and issued substitute restricted stock units in an aggregate amount of $328,000. The value of the total transaction consideration paid amounted to approximately $749.6 million. The Opus warrants assumed by the Corporation expired unexercised on September 30, 2020 and no longer remain outstanding. The Opus options assumed by the Corporation have been fully exercised during the third quarter of 2020. (Dollars in thousands) May 29, 2020 Merger consideration Value of stock consideration paid to shareholders $ 747,458 Cash paid in lieu of fractional shares 2 Value of restricted stock awards 328 Value of options and warrants (1) 1,817 Total merger consideration $ 749,605 ______________________________ (1) The Opus warrants assumed by the Corporation expired unexercised on September 30, 2020 and no longer remain outstanding. The Opus options assumed by the Corporation have been fully exercised during the third quarter of 2020. Core deposit intangible (“CDI”) of $16.1 million, customer relationship intangible assets of $3.2 million, and goodwill of $93.0 million were recognized as a result of the acquisition. Goodwill represents the future economic benefits arising from net assets acquired that are not individually identified and separately recognized and is attributable to synergies expected to be derived from the combination of the two entities. Goodwill recognized in this transaction is not deductible for income tax purposes. The following table summarizes the estimated fair value of assets acquired and liabilities assumed of Opus as of June 1, 2020 under the acquisition method of accounting, net of purchase accounting adjustments: (Dollars in thousands) June 1, 2020 Identifiable net assets acquired, at fair value Assets acquired Cash and cash equivalents $ 937,102 Interest-bearing time deposits with financial institutions 137 Investment securities 829,891 Loans 5,809,451 Allowance for credit losses (21,242) Premises and equipment 22,121 Intangible assets 19,267 Deferred tax assets 43,395 Other assets 369,169 Total assets acquired $ 8,009,291 Liabilities assumed Deposits $ 6,915,990 FHLB advances and other borrowings 213,491 Subordinated debt 138,653 Other liabilities 84,542 Total liabilities assumed 7,352,676 Total fair value of identifiable net assets 656,615 Total merger consideration 749,605 Goodwill recognized $ 92,990 The Company accounted for this transaction under the acquisition method of accounting in accordance with ASC 805, Business Combinations , which requires purchased assets and liabilities assumed and consideration exchanged to be recorded at their respective estimated fair values at the date of acquisition. The determination of estimated fair values required management to make certain estimates about discount rates, future expected cash flows, market conditions at the time of the acquisition, and other future events that are highly subjective in nature and subject to refinement for up to one year after the closing date of acquisition as additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. Since the acquisition, the Company has made a net adjustment of $146,000 related to loans, deferred tax assets, other assets, and other liabilities. In May 2021, the Company finalized its fair values analysis of the acquired assets and assumed liabilities associated with this acquisition. The Company determined the fair value of loans, intangible assets, investment securities, real property, leases, deposits, and borrowings with the assistance of third-party valuations. Loans Opus’s loan portfolio was recorded at fair value at the date of acquisition. A valuation of Opus’s loan portfolio was performed by a third party as of the acquisition date in accordance with ASC 820 to assess the fair value of the loan portfolio, considering adjustments for interest rate risk, required equity return, servicing, credit, and liquidity risk. The loan portfolio was segmented into two groups: non-PCD loans and PCD loans. The non-PCD loans were pooled based on similar characteristics, such as loan type, fixed or adjustable interest rates, payment type, index rate and caps/floors, and non-accrual status. The PCD loans were valued at the loan level with similar characteristics noted above. The fair value was calculated using a discounted cash flow analysis. The discount rate utilized to analyze fair value considered the cost of funds rate, capital charge, servicing costs, and liquidity premium, mostly based on industry standards. At the acquisition date, non-PCD loans and PCD loans had a fair value of $4.94 billion and $841.2 million, respectively, and a contractual balance of $5.05 billion and $896.5 million, respectively. In accordance with GAAP, there was no carryover of the allowance for credit losses that had been previously recorded by Opus. The Company recorded an ACL of $75.9 million through an increase to the provision for credit losses. The initial ACL for PCD loans of $21.2 million is established through an adjustment to the acquired loan balance and goodwill. Core deposit intangible The CDI on non-maturing deposits was determined by evaluating the underlying characteristics of the deposit relationships, including customer attrition, deposit interest rates and maintenance costs, and costs of alternative funding using the discounted cash flow approach. The core deposit intangibles represent the costs saved by the Company between maintaining the existing deposits and obtaining alternative funds over the life of the deposit base. Customer relationship intangible PENSCO operated as the legal custodian for its clients to provide recurring custodial services over the life of client’s custodial agreement. PENSCO could separately identify each of its customer relationships through the custodial agreement between each customer and PENSCO, as well as account-level specific information, and has a history and pattern of conducting business with them as their legal custodian. In the event that PENSCO (or its successor trust division within the Bank) were to merge, reorganize, get acquired, or change its name, the surviving entity will become the trustee or custodian of the IRAs provided that the surviving entity is authorized to serve in that capacity pursuant to the Internal Revenue Code. Accordingly, such PENSCO client relationships met the contractual or other legal rights criterion for identification as a recognizable intangible asset separate from goodwill. The fair value of the customer relationship intangible asset was determined through the use of an excess earnings model associated with the expected fee income associated with underlying client relationships. Fixed maturity deposits In determining the fair value of certificates of deposit, the cash flows of the contractual interest payments during the specific period of the certificates of deposit and scheduled principal payout were discounted to present value at market-based interest rates. FHLB advances The fair value of fixed rate FHLB advances was determined using a discounted cash flow approach. The cash flows of the advances were projected based on scheduled payments of the fixed rate advances, factoring in prepayment fee. The cash flows were then discounted to present value using the FHLB rates as of May 29, 2020. Subordinated debt The fair value of subordinated debt was determined by using a discounted cash flow method using a market participant discount rate for similar instruments. The Company incurred $5,000 of expenses in connection with the Opus acquisition during the year ended December 31, 2021. Merger-related expenses are included in other expense in the Company's consolidated statements of income. The following table presents certain unaudited pro forma financial information for illustrative purposes only, for the years ended December 31, 2020 and 2019 as if Opus had been acquired on January 1, 2019. This unaudited pro forma information combines the historical results of Opus with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Quarterly Cash Dividend On January 18, 2022, the Corporation's Board of Directors declared a $0.33 per share dividend, payable on February 11, 2022 to stockholders of record on February 4, 2022. Transfers of investment securities available-for-sale to held-to-maturity The Company reassessed classification of certain investments, and effective January 1, 2022, the Company transferred approximately $177.7 million of municipal bonds from available-for-sale to held-to-maturity securities at fair value. These securities had an unrealized gain of $1.1 million at the transfer date, which was reflected as a premium on the date of transfer. This premium, as well as the related unrealized gain in accumulated other comprehensive income, will be amortized into interest income as a yield adjustment over the remaining term of the securities. The amortization of the unrealized gain reported in accumulated other comprehensive income will offset the effect on interest income of the amortization of the premium. No gains or losses were recorded at the time of transfer.

Accounting Policies [Abstract]
Description of Business	Description of Business. Pacific Premier Bancorp, Inc., a Delaware corporation organized in 1997 (the “Corporation”), is a California-based bank holding company that owns 100% of the capital stock of Pacific Premier Bank, a California-chartered commercial bank (the “Bank,” and together with the Corporation and its consolidated subsidiaries, the “Company”), the Corporation’s principal operating subsidiary. The Bank was incorporated and commenced operations in 1983. The principal business of the Company is attracting deposits from the general public and investing those deposits, together with funds generated from operations and borrowings, primarily in business loans and commercial real estate loans. At December 31, 2021, the Company had 61 full-service depository branches located in the western United States in major metropolitan markets in California, Washington, Oregon, Arizona, and Nevada. The Company also offers IRA custodial and maintenance services through its Pacific Premier Trust division, which serves as a custodian for self-directed IRAs, the funds of which account owners use for self-directed investments in various alternative asset classes. Additionally, the Company provides commercial escrow services through its Commerce Escrow division, which facilitates tax-deferred commercial exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). The Company is subject to the regulations of certain governmental agencies, and undergoes periodic examinations by those regulatory authorities.
Principles of Consolidation	Principles of Consolidation. The Consolidated Financial Statements include the accounts of the Corporation and its wholly-owned subsidiary the Bank. The Company is organized and operates as a single reporting segment, principally engaged in the commercial banking business. All significant intercompany accounts and transactions have been eliminated in consolidation.
Basis of Financial Statement Presentation	Basis of Financial Statement Presentation. The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). Certain amounts in the financial statements and related footnote disclosures for the prior years have been reclassified to conform to the current presentation with no impact to previously reported net income or stockholders’ equity.
Use of Estimates	Use of Estimates. The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates, and those estimates may change as new information is obtained.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash and cash equivalents include cash on hand, cash balances due from banks, and federal funds sold. Interest-bearing deposits with financial institutions represent primarily cash held at the Federal Reserve Bank of San Francisco. The Board of Governors of the Federal Reserve System (“Federal Reserve”) has cash reserve requirements for depository institutions based on the amount of deposits held. At December 31, 2021, the Bank had no required balance by the Federal Reserve. The Company maintains amounts due from banks that exceed federally insured limits. The Company has not experienced any losses in such accounts.
Securities	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 or available-for-sale 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/Available-for-sale	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. The Company accounts for transfers of debt securities from the available-for-sale classification to the held-to-maturity classification at fair value on the date of transfer. Any associated unrealized gains or losses on such securities as of the date of transfer become part of the security’s amortized cost and are subsequently amortized or accreted into interest income over the remaining life of the security using the interest method. In addition, the related unrealized gains and losses included in accumulated other comprehensive income on the date of transfer are also subsequently amortized or accreted into interest income over the remaining life of the security using the interest method. 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 using 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 from sales of investment securities.
Allowance for Credit Losses on Investment Securities	Allowance for Credit Losses on Investment Securities. The allowance for credit losses (“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, which became effective for the Company on January 1, 2020. The ACL for investment securities is evaluated on a quarterly basis. The ACL for held-to-maturity investment securities is recorded at the time of purchase or acquisition, representing the Company’s best estimate of current expected credit losses (“CECL”) as of the date for the consolidated statements of financial condition. The ACL for held-to-maturity investment securities is determined on a collective basis, based on shared risk characteristics, and is determined at the individual security level when the Company deems a security to no longer possess shared risk characteristics. For investment securities where the Company has reason to believe the credit loss exposure is remote, such as those guaranteed by the U.S. government or other government enterprises, a zero credit loss assumption is applied. For available-for-sale investment securities, the Company performs a 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, or a portion thereof, is credit related, 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 are recorded, 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. 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.
Equity Investments	Equity Investments . Equity investments that have readily determinable fair values are carried at fair value with changes in fair value recognized in current period earnings as a component of noninterest income. Equity investments that do not have readily determinable fair values are carried at cost, adjusted for any observable price changes in orderly transactions for identical or similar investments of the same issuer. Such investments are also recorded net of any previously recognized impairment. Certain equity securities the Company holds, such as investments in the stock of the Federal Home Loan Bank and the Federal Reserve Bank of San Francisco are carried at cost, less any previously recognized impairment. Investment in these securities is restricted to member banks and the securities are not actively traded on an exchange. The Company applies the equity method of accounting to investments in the equity of certain entities where it is deemed to have the ability to exercise significant influence over the entity, but does not control the entity, such as when its ownership interest is between 20% and 50%. Further, the Company also applies the equity method of accounting to equity investments it makes in limited partnerships and limited liability companies when its ownership interest in such entities exceeds 5% or when the Company has the ability to exercise significant influence over the partnership. Such investments typically reflect equity interests in various partnerships that make investments qualifying for credit under the Community Reinvestment Act (“CRA”). The Company records its share of the operating results associated with equity method investments, based on the most recent information available from the investee, in other noninterest income in the consolidated statements of income.
Federal Home Loan Bank Stock	Federal Home Loan Bank Stock. The Bank is a member of the Federal Home Loan Bank (“FHLB”) System. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.
Federal Reserve Bank Stock	Federal Reserve Bank Stock. The Bank is a member of the Federal Reserve Bank of San Francisco (the “FRB”). FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are recorded as a component of interest income.
Loans Held for Sale	Loans Held for Sale. Loans that the Company has the intent to sell prior to maturity have been designated as held for sale at origination or when the determination is made to sell the loan. Such loans are recorded at the lower of cost or fair value. Gains or losses are recognized upon the sale of the loans on a specific identification basis. Origination fees and costs are deferred until the time of sale and are included in the calculation of the gain or loss on the sale of the loan.
Loan Servicing Assets	Loan Servicing Assets. Servicing assets are related to SBA loans sold and are recognized at the time of sale when servicing is retained with the income statement effect recorded in gains on sales of SBA loans. Servicing assets are initially recorded at fair value based on the present value of the contractually specified servicing fee, net of estimated servicing costs, over the estimated life of the loan. The Company’s servicing costs approximates the industry average servicing costs of approximately 40 basis points. The servicing assets are subsequently amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying loans. The Company periodically evaluates servicing assets for impairment based upon the fair value of the assets as compared to their carrying amount.
Loans Held for Investment/Investor Loans Secured by Real Estate/Acquired Loans	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, net of discounts and premiums on acquired and purchased 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 in interest income as an adjustment of yield, using the interest method, over the expected life of the loans. Amortization of deferred loan fees and costs are discontinued for loans that are placed on nonaccrual. Any remaining discounts, premiums, deferred fees or costs, and prepayment fees associated with loan payoffs 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 the collection of principal and or interest. When loans are placed on nonaccrual status, all previously accrued and uncollected interest 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 deemed 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, changes in market rents, and vacancy of the underlying property, any of 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. • Multifamily - Multifamily loans are secured by multi-unit (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 multifamily 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. Risks associated with these loans include material decreases in the value of real estate being held as collateral, and the borrower’s inability to pay as a result of increases in interest rates or decreases in cash flow from the underlying business. • 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. 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. Loan types include revolving lines of 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 commercial and industrial loans. We also issue letters of credit on behalf of our customers. Risk associated with commercial and industrial loans 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, and occasionally upon other borrower assets and guarantor assets. The fair value of the collateral securing these loans may fluctuate 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 first lien single family loans, 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. Risk arises with these loans in the borrower’s inability to pay and decreases in the fair value of the underlying collateral. Acquired Loans. When the Company acquires loans through purchase or a business combination, an assessment is first performed to determine if such loans have experienced more than insignificant deterioration in credit quality since their origination and thus should be classified as purchased credit deteriorated (“PCD”) loans or otherwise classified as non-PCD loans. All acquired loans are recorded at their fair value on the date of acquisition. Any resulting discount or premium recorded on acquired loans is accreted or amortized into interest income over the remaining life of the loans 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 ACL methodology. 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. Unlike non-PCD loans, the initial ACL for PCD loans is established through an adjustment to the acquired loan balance on the date of acquisition and not through a charge to the provision for credit losses. As with non-PCD loans, the ACL for PCD loans is determined with the use of the Company’s ACL methodology. Characteristics of PCD loans typically include: delinquency, downgrade in credit quality since origination, loans on nonaccrual status, loans modified in a troubled debt restructuring, 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. Subsequent to acquisition, the ACL for both non-PCD and PCD loans are measured with the use of the Company’s ACL methodology in the same manner as all other loans. In connection with the Opus acquisition on June 1, 2020, the Company acquired PCD loans with an aggregate fair value of approximately $841.2 million, and recorded an initial ACL of approximately $21.2 million, which was added to the amortized cost of the loans on the date of acquisition.
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 was effective for the Company on January 1, 2020. ASC 326 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 and not 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 probability of default and loss given default based on economic forecast scenarios over a two-year time horizon before reverting to long-term historical average loss rates over a period of three years. 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 for term loans represents the amount by which the loan’s amortized cost exceeds the net present value of a loan’s discounted cash flows expected to be collected. The ACL for credit facilities is determined by discounting estimates for cash flows not expected to be collected. 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 uncollectible. 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 itself, 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 backtesting, 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, which have exhibited a deterioration in credit quality 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 the 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. Additionally, 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 ACL based on judgments different from those of management. Please also see Note 5 - Allowance for Credit Losses , of these Consolidated Financial Statements for additional discussion concerning the Company’s ACL methodology, including discussion concerning economic forecasts used in the determination of the ACL.
Troubled Debt Restructurings	Troubled Debt Restructurings. 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, reductions 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, and the borrower’s performance under the modified terms of the loan agreement and the ultimate collectability of all contractual amounts due under the modified terms 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 estimated costs to sell.
Allowance for Loan Losses	Allowance for Loan Losses. Prior to the Company’s adoption of ASC 326 on January 1, 2020, the Company maintained an allowance for loan and leases losses (“ALLL”) in accordance with ASC 310, Receivables and ASC 450, Contingencies , which represented an ALLL for individually evaluated loans that were identified as impaired, as well as estimated probable incurred losses inherent in the remainder of the loan portfolio as of the date of the consolidated statements of financial condition. Management’s determination of the adequacy of the ALLL was based on an evaluation of the composition of the portfolio, actual historical loss experience, industry charge-off experience on income property loans, current economic conditions and other relevant factors in the area in which the Company’s lending and real estate activities were based. These factors may affect a borrower’s ability to pay as well as the value of the underlying collateral securing loans. The allowance was calculated by applying loss factors to loans held for investment according to loan type and loan credit classification. The loss factors were based primarily upon the Bank’s historical loss experience and industry charge-off experience, and were evaluated on a quarterly basis. Loan credit classifications were based on an internal loan review system, which was designed to provide for the detection of problem loans and assign an appropriate level of ALLL to them. The ALLL was periodically adjusted to reflect the estimated potential impact that relevant internal and external factors may have had on losses inherent in the loan portfolio. These factors typically consisted of: • Changes in lending policies and procedures, including underwriting standards and collection, charge-offs, and recovery practices; • Changes in the nature and volume of the loan portfolio, including new types of lending; • Changes in the experience, ability, and depth of lending management and other relevant staff that may have an impact on our loan portfolio; • Changes in the volume and severity of adversely classified or graded loans; • Changes in the quality of our loan review system and the management oversight; • The existence and effect of any concentrations of credit and changes in the level of such concentrations; • Changes in national, regional, and local economic conditions, including trends in real estate values and the interest rate environment; • Changes in the value of the underlying collateral for collateral-dependent loans; and • The effect of external factors, such as competition, legal developments, and regulatory requirements on the level of estimated credit losses in our current loan portfolio.
Impaired Loans	Impaired Loans. Prior to the Company’s adoption of ASC 326 on January 1, 2020, the Company classified a loan as impaired when it was probable that the Company would be unable to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement. 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, or when the borrower filed bankruptcy or was granted a concession which qualified as a troubled debt restructuring. Measurement of impairment was based on the amount by which a loan’s carrying value exceeds its expected future cash flows discounted at the loan’s effective interest rate, an observable market value, if one exists, or the fair value of the collateral if the loan was deemed collateral dependent. Impairment was recorded through the provision for loan losses. The Company measured impairment on a loan-by-loan basis, and generally charged-off specific reserves for impaired loans at such time the loan or a portion thereof was classified as a loss.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments. Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recognized in the Consolidated Financial Statements when they are funded.
Other Real Estate Owned	Other Real Estate Owned. 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.
Premises and Equipment	Premises and Equipment. Premises and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, which range from twenty years for buildings, seven years for furniture, fixtures and equipment, and three years for computer and telecommunication equipment. The cost of leasehold improvements is amortized using the straight-line method over the shorter of the estimated useful life of the asset or the term of the related leases. The Company periodically evaluates the recoverability of long-lived assets, such as premises and equipment, to ensure the carrying value has not been impaired. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
Bank Owned Life Insurance (“BOLI”)	Bank-Owned Life Insurance (“BOLI”). BOLI assets are life insurance policies on certain current and former officers, directors and employees for which the Bank is the beneficiary under each policy. BOLI is accounted for using the cash surrender value method and is recorded at its realizable value as an asset in the consolidated statements of financial condition. Changes in the cash surrender value of BOLI and the death benefits of an insured individual covered by these policies, after distribution to the insured’s beneficiaries, if any, are recorded as tax-exempt noninterest income in the consolidated statements of income.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets. Goodwill assets originate from business combinations where the Company has acquired other financial institutions, and is 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 that are determined to have indefinite useful lives are not amortized, but tested for impairment at least annually or more frequently if events and circumstances lead management to believe the value of those assets may be impaired. Impairment testing is performed at the reporting unit level, which is considered the Company level as management has identified the Company is its sole reporting unit as of December 31, 2021. Management’s assessment of goodwill is performed in accordance with ASC 350-20 - Goodwill and Other - Goodwill , which allows the Company to first perform a qualitative assessment of goodwill to determine if it is more likely than not the fair value of the Company’s equity is below its carrying value. However, GAAP also allows the Company, at its option, to unconditionally forego the qualitative assessment and proceed directly to a quantitative assessment. When performing a qualitative assessment of goodwill, should the results of such analysis indicate it is more likely than not the fair value of the Company’s equity is below its carrying value, the Company then performs the quantitative assessment of goodwill to determine the fair value of the reporting unit and compares it to its carrying value. If the fair value of the reporting unit is below its carrying value, the Company would then recognize the amount of impairment as the amount by which the reporting unit’s carrying value exceeds its fair value, limited to the total amount of goodwill allocated to the reporting unit. Impairment losses are recorded as a charge to noninterest expense. The Company’s annual impairment test of goodwill is performed in the fourth quarter. The Company performed a qualitative assessment of goodwill in the fourth quarter of 2021, the results of which indicated the value of goodwill assets could be supported and were not impaired. As of December 31, 2021, goodwill is the only intangible asset with an indefinite life recorded in the Company’s consolidated statements of financial condition. Other intangible assets include core deposit and customer relationship intangibles arising from the acquisition of other financial institutions and are amortized on a basis reflecting the pattern in which the economic benefits of the intangible asset are expected to be consumed or otherwise used up, or on a straight-line basis over their estimated useful lives, which ranges from six intangible assets could be supported and were not impaired.
Derivatives as Part of Designated Accounting Hedges	Derivatives as Part of Designated Accounting Hedges. The Company applies hedge accounting to certain derivative instruments used for risk management purposes, primarily associated with interest rate risk. To qualify for hedge accounting, a derivative instrument must be highly effective at reducing the risk associated with the hedged exposure, and the hedging relationship must be formally documented at its inception. The Company uses regression analysis to assess the effectiveness of each hedging relationship, unless the hedge qualifies for other methods of assessing effectiveness (e.g., shortcut or critical terms match), both at inception and throughout the life of the hedge transaction.
Business Combinations	Business Combinations . The company accounts for business combinations under the acquisition method of accounting. Upon obtaining control of the acquired entity, the Company records all identifiable assets and liabilities at their estimated fair values. Goodwill is recorded when the consideration paid for an acquired entity exceeds the estimated fair value of the net assets acquired. Changes to the acquisition date fair values of assets acquired and liabilities assumed may be made as adjustments to goodwill over a one year measurement period following the date of acquisition. Such adjustments are attributable to additional information obtained related to fair value estimates of the assets acquired and liabilities assumed. Costs associated with business combinations are reflected as a component of noninterest expense.
Subordinated Debentures	Subordinated Debentures. Long-term borrowings are carried at cost, adjusted for amortization of premiums and accretion of discounts, which are recognized in interest expense using the interest method. Debt issuance costs are included in the carrying value of associated borrowings and are subsequently recognized in interest expense using the interest method over the life of the borrowing.
Leases	Leases . The Company accounts for its leases in accordance with ASC 842 - Leases , 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 right-of-use 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 future contractual 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 contractual rents based on the minimum payments specified in the lease agreement from the date the lease commences, 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 future lease payments on operating leases are 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 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 operating leases is recorded on a straight-line basis. As of December 31, 2021, 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.
Revenue Recognition	Revenue Recognition . The Company accounts for certain of its revenue streams deemed to arise from contracts with customers 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, custodial account 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. These revenue streams are included in noninterest income in the consolidated statements of income. 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. Revenue is measured as the amount of consideration that Company expects to receive in exchange for the transfer of goods or services to the associated customer. 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, such as a deposit account agreement, which may be cancelled at any time, or a service provided to a customer at a point in time. 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 GAAP.
Stock-Based Compensation	Stock-Based Compensation. The Company issues various forms of stock-based compensation awards annually to officers and directors of the Company, including stock options, restricted stock awards, and restricted stock units. The related compensation costs are based on the grant-date fair value and are recognized in the income statement over the period they are expected to vest, net of estimates for forfeitures. Estimates for forfeitures are based on the Company’s historical experience for each award type. A Black-Scholes model is utilized to estimate the fair value of stock options on the grant date. The Black-Scholes model uses certain assumptions to determine grant-date fair value such as: expected volatility, expected term of the option, expected risk-free rate of interest, and expected dividend yield on the Corporation’s common stock. The market price of the Corporation’s common stock at the grant date is used for restricted stock awards in determining the grant date fair value for those awards. Restricted stock awards and restricted stock units are granted to employees of the Company, and represent stock-based compensation awards that when ultimately settled, result in the issuance of shares of the Corporation’s common stock to the grantee. As with other stock-based compensation awards, compensation cost for restricted stock awards and restricted stock units is recognized over the period in which the awards are expected to vest. Certain of the Corporation’s restricted stock units contain vesting conditions which are based on pre-determined performance targets. The level at which the associated performance targets are achieved can impact the ultimate settlement of the award with the grantee and thus the level of compensation expense ultimately recognized. Certain of these awards contain a market-based condition whereby the vesting of the award is based on the Company’s performance, such as total shareholder return, relative to its peers over a specified period of time. The grant date fair value of market-based restricted stock units is determined through an independent third party which employs the use of a Monte Carlo simulation. The Monte Carlo simulation estimates grant date fair value using input assumptions similar to those used in the Black-Scholes model, however, it also incorporates into the grant date fair value calculation the probability that the performance targets will be achieved. The grant date fair value of restricted stock units that do not contain a market-based condition for vesting is based on the price of the Corporation’s common stock on the grant date. Holders of restricted stock awards are entitled to receive cash dividends. Holders of restricted stock units are entitled to receive dividend equivalents during the vesting period commensurate with dividends declared and paid on the Corporation’s common stock. As restricted stock awards contain rights to receive non-forfeitable dividends prior to the awards being vested, such awards are considered participating securities.
Income Taxes	Income Taxes. Deferred tax assets and liabilities are recorded for the expected future tax consequences of events that have been recognized in the Company’s financial statements or tax returns using the asset liability method. In estimating future tax consequences, all expected future events other than enactments of changes in the tax law or rates are considered. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years and for tax carryforwards if, in the opinion of management, it is more likely than not that the deferred tax assets will be realized. At December 31, 2021 and 2020, no valuation allowance was deemed necessary against the Company’s deferred tax assets. A tax position is recognized as a benefit only if it is more likely than not that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that management believes is more likely than not to be realized upon examination. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.
Earnings per Share	Earnings per Share. Earnings per share of common stock is calculated on both a basic and diluted basis, based on the weighted average number of common and common equivalent shares outstanding. Basic earnings per share excludes potential dilution from common equivalent shares, such as those associated with stock-based compensation awards, and is computed by dividing net income allocated to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock, such as common equivalent shares associated with stock-based compensation awards, were exercised or converted into common stock that would then share in the net earnings of the Corporation. Potential dilution from common equivalent shares is determined using the treasury stock method, reflecting the potential settlement of stock-based compensation awards resulting in the issuance of additional shares of the Corporation’s common stock. Stock-based compensation awards that would have an anti-dilutive effect have been excluded from the determination of earnings per common share. Restricted stock awards are deemed participating securities by the Corporation, and therefore the Corporation applies the two-class method when considering these awards in the computation of earnings per common. Under the two-class method, distributed and undistributed net 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. Participating securities are excluded from the denominator of both basic and diluted earnings per common share.
Comprehensive Income	Comprehensive Income. Comprehensive income is reported in addition to net income for all periods presented. Comprehensive income is a more inclusive financial reporting methodology that includes disclosure of other comprehensive income (loss) that historically has not been recognized in the calculation of net income. Unrealized gains and losses on the Company’s available-for-sale investment securities are required to be included in other comprehensive income or loss. Total comprehensive income (loss) and the components of accumulated other comprehensive income or loss are presented in the Consolidated Statements of Stockholders’ Equity and Consolidated Statements of Comprehensive Income.
Loss Contingencies	Loss Contingencies. Loss contingencies, including claims and legal action arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there now are such matters that will have a material effect on the financial statements.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 17 - Fair Value of Financial Instruments . Fair value is an exit price, representing the amount that would be received to sell an asset or transfer a liability in an orderly transaction between market participants. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Fair value measures are classified according to a three-tier fair value hierarchy, which is based on the observability of inputs used to measure fair value. GAAP requires the Company to maximize the use of observable inputs when measuring fair value. When observable market prices or inputs are not available, the Company estimates fair value using modeling techniques such as a discounting future cash flows. Such a technique uses assumptions that market participants would consider in determining the fair value of the financial asset or liability. Changes in assumptions or in market conditions could significantly affect fair value estimates. 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. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. 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 for certain instruments measured at fair value, as well as the general classification of these instruments pursuant to the valuation hierarchy. Investment securities – Investment securities are generally valued based upon quotes obtained from an independent third-party pricing service, which uses 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. Interest rate swaps – 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 Company also enters into interest rate swap contracts with institutional counterparties to hedge against certain fixed-rate loans. 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 incorporates credit value adjustments on derivatives to properly reflect the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. The Company has determined that the observable nature of the majority of inputs used in deriving the fair value of these derivative contracts fall within Level 2 of the fair value hierarchy, and the credit valuation adjustments are not significant to the overall valuation of its derivative financial instruments. As a result, the valuation of interest rate swaps is classified as Level 2 of the fair value hierarchy. Equity warrant assets – The Company acquired equity warrant assets as a result of the acquisition of Opus. Opus received equity warrant assets through its lending activities as part of loan origination fees. The warrants provide the Bank the right to purchase a specific number of equity shares of the underlying company’s equity at a certain price before expiration and contain net settlement terms qualifying as derivatives under ASC Topic 815. The fair value of equity warrant assets is determined using a Black-Scholes option pricing model and are classified as Level 3 of the fair value hierarchy due to the extent of unobservable inputs. The key assumptions used in determining the fair value include the exercise price of the warrants, valuation of the underlying entity's outstanding stock, expected term, risk-free interest rate, marketability discount for private company warrants, and price volatility. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Individually evaluated Loans – 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 and it does not share similar risk characteristics with other loans. Individually evaluated loans are 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. The fair value of individually evaluated collateral dependent loans were determined using Level 3 assumptions, and represents individually evaluated loan 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 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.
Variable Interest Entities	Variable Interest Entities. A VIE is consolidated in the Company’s financial statements when it is deemed the Company is the primary beneficiary of the VIE. GAAP requires analysis at the time of commencement of our involvement with a VIE, to determine the primary beneficiary and whether it should be consolidated in the Company’s financial statements. The Company continually performs analysis to determine the primary beneficiary of a VIE.The Company is involved with VIEs through its loan securitization activities, affordable housing investments that qualify for the low-income housing tax credit, and trust subsidiaries, which have issued trust preferred securities. The Company has determined that its interests in these entities meet the definition of variable interests.
Reclassifications	Reclassifications. Some items in prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or stockholders’ equity.
Recently Issued Accounting Pronouncements	Accounting Standards Adopted in 2021 In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes , which includes updates to Topic 740 - Income Taxes . The amendments to this Update include the removal of the following exceptions included in Topic 740: (1) Exception to the general intra-period tax allocation principle when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); (2) Exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; (3) Exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; and (4) Exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments included in this update also require the following: (1) Requiring that an entity recognize a franchise tax by (i) accounting for the amount based on income under Accounting Standards Codification (“ASC”) 740 and (ii) accounting for any residual amount as a non-income-based tax. (2) Requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction. (3) Specifying that an entity is not required to allocate any portion of the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements. However, an entity may elect to do so (on an entity-by-entity basis) for a legal entity that is both not subject to tax and disregarded by the taxing authority. (4) Requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. (5) Making minor Codification improvements for tax benefits related to tax-deductible dividends on employee stock ownership plan shares and investments in qualified affordable housing projects accounted for using the equity method. The amendments within this Update became effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The Company’s adoption of this Update did not have a material impact on its Consolidated Financial Statements. 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 . The amendments in this Update clarify the interaction of the accounting for equity securities under Topic 321 and investments under the equity method of accounting in Topic 323, as well as the accounting for certain forward contracts and purchased options accounted for under Topic 815. The amendments clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments within this Update also clarify that when applying the guidance in paragraph 815-10-15-141(a) an entity should not consider whether, upon the settlement of the forward contract or exercise of the purchased option, individually or with existing investments, the underlying securities would be accounted for under the equity method in Topic 323 or the fair value option in accordance with the financial instruments guidance in Topic 825. An entity also would evaluate the remaining characteristics in paragraph 815-10-15-141 to determine the accounting for those forward contracts and purchased options. The amendments within this Update became effective for public business entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. The Company’s adoption of this Update did not have a material impact on its financial statements. In October 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2020-08, Codification Improvements to Subtopic 310-20, Receivables - Nonrefundable Fees and Other Costs . The amendments included in this Update are intended to clarify that an entity should reevaluate whether a callable debt security is within the scope of paragraph 310-20-35-33 for each reporting period. The guidance in paragraph 310-20-35-33 relates to amortization of premiums on individual callable debt securities and the period over which the premium shall be amortized in relation to the date the security is callable. For public business entities, the amendments in this Update became effective for fiscal years beginning after December 15, 2020, and interim periods within those years. The Company’s adoption of this Update did not have a material impact on its Consolidated Financial Statements. Recent Accounting Guidance Not Yet Effective 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. The Company has not yet made a determination on whether it will make this election and is currently tracking the exposure as of each reporting period and assessing the significance of impact towards implementing any necessary modification in consideration of the election of this amendment. 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. The Company has not entered into any hedging related transactions that reference LIBOR or another reference rate that is expected to be discontinued, and as such, the amendments included in this Update have not had an impact on the Company’s consolidated financial statements. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848) . The amendments included in this Update clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the worldwide transition to new reference rates (commonly referred to as the “discounting transition”). Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. Amendments in this Update are to the expedients and exceptions in Topic 848 and capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The amendments in this Update are effective immediately for all entities that elect to apply the optional guidance in Topic 848. An entity may elect to apply the amendments in this Update on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or on a prospective basis to new modifications from any date within an interim period that includes or is subsequent to the date of the issuance of a final Update, up to the date that financial statements are available to be issued. The Company is currently evaluating the impact of this Update on its consolidated financial statements, upon which this accounting guidance is not expected to have a material impact. The Company has created a cross-functional working group to manage the transition away from LIBOR. Under the oversight of the Enterprise Risk Committee, this working group is comprised of senior leadership and staff from functional areas that include: finance, treasury, lending, loan servicing, enterprise risk management, information technology, legal, and other internal stakeholders integral to the Bank’s transition away from LIBOR. The working group monitors developments related to transition and uncertainty surrounding reference rate reform and guides the Bank’s response. The working group is currently assessing the population of financial instruments that reference LIBOR, confirming our loan documents that reference LIBOR have been appropriately amended, ensuring that our internal systems are prepared for the transition, and managing the transition process with our customers. The Company has chosen to use the Secured Overnight Financing Rate (“SOFR”) as an alternative to LIBOR. However, the Company will also use other alternative reference rates, such as the Constant Maturity Treasury (“CMT”) index and Prime based on the individual needs of its customers as well as the types of credit being extended. In October 2021, the FASB issued ASU 2021-08, Business Combinations - Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . The amendments in this Update address how to determine whether a contract liability is recognized by an acquirer in a business combination. In addition, the Update addresses inconsistencies in the recognition and measurement of acquired contract assets and contract liabilities from revenue contracts in a business combination. The amendments in this Update are effective for the Company in fiscal years beginning after December 15, 2022 as well as all interim periods within those years. Early adoption is permitted. An entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application, and (2) prospectively to all business combinations that occur on or after the date of initial application. The Company has not yet adopted the provisions of this Update. The Company does not currently anticipate the adoption of this Update will have a material impact on the Company’s Consolidated Financial Statements.

Summary of pro forma financial information	The following table presents certain unaudited pro forma financial information for illustrative purposes only, for the years ended December 31, 2020 and 2019 as if Opus had been acquired on January 1, 2019. This unaudited pro forma information combines the historical results of Opus with the Company’s consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. The unaudited pro forma information does not consider any changes to the provision for credit losses resulting from recording loan assets at fair value, cost savings, or business synergies. As a result, actual amounts would have differed from the unaudited pro forma information presented and the differences could be significant.
