At December 31, 2023, the Company had 58 full-service depository branches located in the Western Region of the U.S. in major metropolitan markets in Arizona, California, Nevada, and Washington. The Company also offers IRA custodial and maintenance services through its Pacific Premier Trust division, which serves as a custodian for self-directed IRAs as well as certain accounts that do not qualify as IRAs pursuant to the Internal Revenue Code. Account owners use the funds for self-directed investments in various alternative asset classes. Additionally, the Company provides commercial escrow and exchange services through its Commerce Escrow division, which facilitates commercial escrow services and tax-deferred commercial real estate exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). The Company is also 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. Basis of Financial Statement Presentation. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the U.S. (“GAAP”). Certain amounts in the consolidated financial statements and the related footnote disclosure for the prior periods have been reclassified to conform to the current presentation. Reclassifications had no effect on net income or stockholders’ equity as previously reported. 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, federal funds sold and cash items in the process of collection. Interest-bearing deposits with financial institutions primarily represent 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, 2023, 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 securities as either held-to-maturity or available-for-sale, or held-for-trading based on the Company’s investment objectives, operational needs, and intent. Investments are monitored to ensure that those activities are consistent with the established guidelines and objectives. Securities Held-to-Maturity (“HTM”). Investments in debt securities that management has the positive intent and ability to hold to maturity are reported at amortized cost. The amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the period of time remaining to an 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 (loss) 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 (“AFS”). 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 first 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 accumulated other comprehensive income (loss). 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 (loss) on investment securities. Allowance for Credit Losses (“ACL”) on Investment Securities. The ACL on investment securities is determined for both the HTM and AFS classifications of the investment portfolio in accordance with ASC 326 on a quarterly basis. The ACL for HTM 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 of the consolidated statements of financial condition. The ACL for HTM 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 risk characteristics similar with others in the portfolio. For investment securities where the Company has reason to believe the credit loss exposure is remote, a zero credit loss assumption is applied. Such investment securities typically consist of those guaranteed by the U.S. government or other government enterprises, where there is an explicit or implicit guarantee by the U.S. government, that are highly rated by rating agencies, and historically have had no credit loss experience. For AFS 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, in accumulated other comprehensive income (loss). The Company determines the amount of expected credit losses on AFS and HTM securities through a discounted cash flow approach, using the security’s effective interest rate. 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 AFS 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. Dividends received on equity securities are included in interest income on investment securities and other interest earning assets in the consolidated statements of income. 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 3-5% or when the Company has the ability to exercise significant influence over the entity. Such investments typically reflect equity interests in various partnerships that make investments qualifying for credit under the Community Reinvestment Act (“CRA”) and are recorded in other assets of the consolidated statements of financial condition. 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. Ownership of FHLB stock is restricted to member banks and is not actively traded on an exchange. 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”). Ownership of FRB stock is restricted to member banks and is not traded on an exchange. 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 for which the Company does not have the intent or ability to hold for the foreseeable future are designated as held for sale at their 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 determination of the gain or loss on the sale of the loan. Loan Servicing Assets. Servicing assets are related to U.S. Small Business Administration (“SBA”) loans sold and are recognized at the time of sale when servicing is retained with the income statement effect recorded in net gain on sales of 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 for the foreseeable future, or 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 contractual life of the loans. Accretion or amortization of deferred loan fees and costs or discounts and premiums 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 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 the 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 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 (“PD”) and loss given default (“LGD”) model, whereby PDs and LGDs are forecasted using economic scenarios over a two-year period to generate estimates for cash flows expected to be collected over the estimated life of a loan. Beyond the two-year forecast time horizon, the Company’s ACL model reverts to historical long-term average loss rates over a period of three years. 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 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. Expectations of future cash flows are discounted at the loan’s effective interest rate. The Company has made an accounting policy election to adjust the effective interest rate to take into consideration the effects of estimated prepayments. 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. 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 provide a sufficient basis for determining future expected credit losses. 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 credit risk grade, and may consist of loans on nonaccrual status, modified loans to troubled borrowers, 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 based on the estimated expected 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 and may require changes to the ACL. Please also see Note 5 – Allowance for Credit Losses 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, 2023, the Company had the following segments and classes of loans: Investor Loans Secured by Real Estate: • Commercial real estate (“CRE”) non-owner-occupied - 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 - 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. government. 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”) - C&I loans are loans that are 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 Homeowners’ Association (“HOA”) credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers. Risk associated with C&I 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 them through bank acquisitions. We originate home equity lines of credit loans to consumers within our market area. 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 to banking clients. Our consumer loans consist primarily of small balance personal unsecured loans and savings account secured loans. Risk arises with these loans in the borrower’s inability to pay and decreases in the fair value of the underlying collateral. Modified Loans to Borrowers Experiencing Financial Difficulty . Infrequently, the Company makes modifications to certain loans in order to alleviate temporary difficulties 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. The Company also refers to these modifications as modified loans to troubled borrowers (“MLTB”). Modifications may include: changes in the amortization terms of the loan, reductions in interest rates, acceptance of interest only payments, and, in very limited cases, reductions to the outstanding loan balance. Such loans are typically placed on nonaccrual status when there is doubt concerning the full repayment of principal and interest or the loan has been in default for a period of 90 days or more. Such loans may be 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

Regulatory Capital Requirements under Banking Regulations [Abstract]
Regulatory Capital Requirements and Other Regulatory Matters	Note 2 – 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. 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, 2023, 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. The cumulative difference at the end of the second year of the transition period is then phased into regulatory capital at 25% per year over a three-year transition period. The final rule was adopted and became effective in September 2020. 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. In the first quarter of 2022, the Company began phasing into regulatory capital the cumulative adjustments at the end of the second year of the transition period at 25% per year. For regulatory capital purposes, the subordinated debentures of the Corporation and the Bank are included in Tier 2 capital at December 31, 2023 and 2022. See Note 13 – Subordinated Debentures for additional information.

During 2023, the Company transferred $410.7 million of AFS collateralized mortgage obligations to HTM securities. The Company intends and has the ability to hold the securities transferred to maturity. The transfer of these securities was accounted for at fair value on the transfer date. These collateralized mortgage obligations securities had a net carrying amount of $360.3 million with a pre-tax unrealized loss of $50.4 million, which are accreted into interest income as yield adjustments through earnings over the remaining term of the securities. The amortization of the related net after-tax unrealized losses reported in accumulated other comprehensive loss offsets the effect on interest income for the accretion of the unrealized losses associated with the transferred securities. No gains or losses were recorded at the time of transfer. During 2022, the Company transferred an AFS municipal bond portfolio of $831.4 million and mortgage-backed securities of $255.0 million to HTM securities. The Company intends and has the ability to hold the securities transferred to maturity. The transfer of these securities was accounted for at fair value on the transfer date. The municipal bonds had a net carrying amount of $780.7 million with a pre-tax unrealized loss of $50.8 million, and the mortgage-backed securities had a net carrying amount of $238.8 million with a pre-tax unrealized loss of $$16.2 million, both of which are accreted into interest income as yield adjustments over the remaining term of the securities. No gains or losses were recorded at the time of transfer. Investment securities with carrying values of $2.80 billion and $195.6 million as of December 31, 2023 and 2022, respectively, were pledged to other borrowings, secure public deposits, and for other purposes as required or permitted by law. The increase in the investment securities pledged during 2023 was primarily due to the additional investment securities with carrying values of $1.41 billion pledged to the Federal Reserve's discount window and $1.19 billion pledged to the Federal Reserve's new Bank Term Funding Program (“BTFP”) launched in March 2023 to increase the Company’s access to funding and provide liquidity. Unrealized Gains and Losses Unrealized gains and losses on AFS investment securities are recognized in stockholders’ equity as accumulated other comprehensive income or loss. At December 31, 2023, the Company had a net unrealized loss on AFS investment securities of $36.0 million, or $25.8 million net of tax in accumulated other comprehensive loss, compared to a net unrealized loss of $303.7 million, or $217.4 million net of tax in accumulated other comprehensive loss, at December 31, 2022. The decrease of net unrealized loss on AFS investment securities was primarily due to the sale of $1.26 billion of AFS of securities at fair value to reposition the balance sheet, resulting in a net realized pre-tax loss of $254.1 million, or $182.3 million net of tax, during the fourth quarter of 2023. For investment securities transferred from AFS to HTM, the net after-tax unrealized gains and losses at the date of transfer continue to be reported in stockholders’ equity as accumulated other comprehensive loss and are amortized over the remaining lives of the securities with an offsetting entry to interest income as an adjustment of yield in a manner consistent with the amortization of a premium or discount, with an offsetting entry to interest income for the accretion of the unrealized loss associated with the transferred securities. At December 31, 2023, the unrealized loss on investment securities transferred from AFS to HTM was $102.9 million, or $73.9 million net of tax. At December 31, 2022, the unrealized loss on investment securities transferred from AFS to HTM was $66.9 million, or $47.9 million net of tax. The table below summarizes the number, fair value, and gross unrealized holding losses of the Company’s AFS investment securities 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 AFS investment securities is recorded when unrealized losses have been deemed, through the Company’s qualitative assessment, to be credit related. Non-credit related unrealized losses on AFS 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 loss, net of tax. In the event the Company is required to sell or has the intent to sell an AFS 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. The ACL for HTM investment securities is estimated 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. Credit losses on HTM investment securities are representative of the amount needed to reduce the amortized cost basis to reflect the net amount expected to be collected. The Company determines credit losses on both AFS and HTM 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 AFS 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. For additional information concerning allowance for credit losses on investment securities, refer to Note 1 – Description of Business and Summary of Significant Accounting Policies , of our audited consolidated financial statements included in this Annual Report on Form 10-K. At December 31, 2023 and 2022, the Company had an ACL of $126,000 and $43,000, respectively, for HTM investment securities classified as municipal bonds. The following table presents a rollforward by major security type of the ACL on the Company's HTM debt securities as of, and for the periods indicated: For the Year Ended December 31, 2023 (Dollars in thousands) Balance, December 31, 2022 Provision for Credit Losses Balance, December 31, 2023 HTM Investment securities: Municipal bonds $ 43 $ 83 $ 126 For the Year Ended December 31, 2022 (Dollars in thousands) Balance at December 31, 2021 Provision for Credit Losses Balance, December 31, 2022 HTM Investment securities: Municipal bonds $ 22 $ 21 $ 43 The Company had no ACL for AFS investment securities at December 31, 2023 and 2022. The Company performed a qualitative assessment of the AFS investment securities as of December 31, 2023 and determined that the unrealized losses during 2023 were the result of general market conditions, including changes in interest rates driven by the Federal Reserve’s policy to reduce levels of inflation, and does not believe the declines in fair value were credit related. As of December 31, 2023, the Company has not recorded credit losses on certain AFS 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. As of December 31, 2023, 61% of our AFS securities were U.S. Treasury, U.S. government agency, and U.S. government-sponsored enterprise securities. Additionally, the Company continues to receive contractual principal and interest payments in a timely manner. It is more likely than not that the Company will not be required to sell the securities prior to their anticipated recoveries, and at this time the Company does not intend to sell these securities. There was no provision for credit losses recognized for AFS investment securities during the years ended December 31, 2023 and 2022. At December 31, 2023 and 2022, there were no AFS or HTM securities in nonaccrual status. All securities in the portfolio were current with their contractual principal and interest payments. At December 31, 2023 and 2022, there were no securities purchased with deterioration in credit quality since their origination. At December 31, 2023 and 2022, there were no collateral dependent AFS or HTM securities. Realized Gains and Losses The following table presents the amortized cost of securities sold with related gross realized gains, gross realized losses, and net realized (losses) gains for the periods indicated: For the Year Ended December 31, (Dollars in thousands) 2023 2022 2021 Amortized cost of AFS investment securities sold $ 1,822,531 $ 934,703 $ 884,231 Gross realized gains $ 986 $ 13,645 $ 23,185 Gross realized losses (254,913) (11,935) (6,279) Net realized gains on sales of AFS investment securities $ (253,927) $ 1,710 $ 16,906 During the fourth quarter of 2023, the Company sold $1.26 billion of lower-yielding AFS securities at fair value to reposition the securities portfolio, resulting in a net loss of $254.1 million, and redeployed a portion of the sale proceeds into higher-yielding short-term AFS U.S. Treasury securities. Contractual Maturities The amortized cost and fair value of investment securities at December 31, 2023, by contractual maturity, are shown in the table below.

These equity securities without readily determinable fair values are carried at cost less impairment. At December 31, 2023, the Company had $19.4 million in FHLB stock, $75.2 million in FRB stock, and $4.7 million in other stock. At December 31, 2022, the Company had $27.7 million in FHLB stock, $74.8 million in FRB stock, and $17.4 million in other stock.

Loans Held for Investment	Note 4 – 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 not secured by real estate, 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) 2023 2022 Investor loans secured by real estate CRE non-owner-occupied $ 2,421,772 $ 2,660,321 Multifamily 5,645,310 6,112,026 Construction and land 472,544 399,034 SBA secured by real estate 36,400 42,135 Total investor loans secured by real estate 8,576,026 9,213,516 Business loans secured by real estate CRE owner-occupied 2,191,334 2,432,163 Franchise real estate secured 304,514 378,057 SBA secured by real estate 50,741 61,368 Total business loans secured by real estate 2,546,589 2,871,588 Commercial loans Commercial and industrial 1,790,608 2,160,948 Franchise non-real estate secured 319,721 404,791 SBA non-real estate secured 10,926 11,100 Total commercial loans 2,121,255 2,576,839 Retail loans Single family residential 72,752 72,997 Consumer 1,949 3,284 Total retail loans 74,701 76,281 Loans held for investment before basis adjustment (1) 13,318,571 14,738,224 Basis adjustment associated with fair value hedge (2) (29,551) (61,926) Loans held for investment 13,289,020 14,676,298 Allowance for credit losses for loans held for investment (192,471) (195,651) Loans held for investment, net $ 13,096,549 $ 14,480,647 Total unfunded loan commitments $ 1,703,470 $ 2,489,203 Loans held for sale, at lower of cost or fair value $ — $ 2,643 ____________________________________________________ (1) Includes net deferred origination fees of $74,000 and $1.9 million, and unaccreted fair value net purchase discounts of $43.3 million and $54.8 million as of December 31, 2023 and 2022, respectively. (2) Represents the basis adjustment associated with the application of hedge accounting on certain loans. Refer to Note 19 – Derivative Instruments for additional information. 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. 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 initially 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. At December 31, 2023 and 2022, the servicing assets totaled $1.6 million and $3.0 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, 2023, and 2022, the Company determined that no valuation allowance was necessary. In connection with the acquisition of Opus Bank (“Opus”), the Company acquired Federal Home Loan Mortgage Corporation (“Freddie Mac”) guaranteed structured pass-through certificates, which were issued as a result of Opus’s securitization sale of $509.0 million in originated multifamily loans through a Freddie Mac-sponsored transaction in December 2016. 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. 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 the Company’s exposure to the reimbursement agreement with Freddie Mac was $345,000 and $334,000 as of December 31, 2023 and 2022, 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 $373.8 million and $463.4 million at December 31, 2023 and 2022, respectively. Included in those totals are multifamily loans transferred through securitization with Freddie Mac of $48.0 million and $54.2 million at December 31, 2023 and 2022, respectively, and SBA participations serviced for others totaling $258.1 million and $315.3 million at December 31, 2023 and 2022, respectively. Concentration of Credit Risk As of December 31, 2023, 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 $834.6 million for secured loans and $500.8 million for unsecured loans at December 31, 2023. In order to manage concentration risk, the Bank maintains a house lending limit well below these statutory maximums. At December 31, 2023, the Bank’s largest aggregate outstanding balance of loans to one borrower was $269.4 million, primarily comprised of asset-based lines of credit. Credit Quality and Credit Risk Management 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 and guarantors. 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 consideration 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 both an independent loan review function and periodic internal audits, as well as by regulatory agencies during scheduled examinations. The following provides brief definitions for risk grades assigned to loans in the portfolio: • Pass assets carry 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. Other real estate owned (“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 assets 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. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate properties, and cash. 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. However, if a loan is not considered collateral dependent and management determines that the loan no longer possesses risk characteristics similar to other loans in the loan portfolio, the loan is individually evaluated, and the associated ACL is determined through the use of a discounted cash flow analysis. The following table stratifies the loans held for investment portfolio by the Company’s internal risk grading, and by year of origination, as well as the gross charge-offs on a year-to-date basis by year of origination as of December 31, 2023: Term Loans by Vintage (Dollars in thousands) 2023 2022 2021 2020 2019 Prior Revolving Revolving Converted to Term During the Period Total December 31, 2023 Investor loans secured by real estate CRE non-owner-occupied Pass $ 71,452 $ 482,045 $ 549,828 $ 192,399 $ 315,139 $ 795,856 $ — $ — $ 2,406,719 Special mention — 3,811 2,530 — — 625 — — 6,966 Substandard — 412 — — — 7,675 — — 8,087 Multifamily Pass 179,055 1,184,329 2,008,126 725,123 822,411 714,638 — — 5,633,682 Special mention — — — — — 11,628 — — 11,628 Construction and land Pass 59,993 309,677 94,845 2,223 2,368 3,438 — — 472,544 SBA secured by real estate Pass — 6,478 — 493 4,804 16,496 — — 28,271 Substandard — — 131 — 536 7,462 — — 8,129 Total investor loans secured by real estate 310,500 1,986,752 2,655,460 920,238 1,145,258 1,557,818 — — 8,576,026 Current period gross charge-offs — — 217 — 1,582 3,653 — — 5,452 Business loans secured by real estate CRE owner-occupied Pass 19,014 543,413 660,967 224,333 211,283 458,975 — — 2,117,985 Special mention — 16,535 — 476 4,775 11,775 919 — 34,480 Substandard — 15,539 2,162 5,505 3,873 11,790 — — 38,869 Franchise real estate secured Pass 10,580 39,239 124,424 25,697 15,731 72,342 — — 288,013 Special mention 1,758 3,603 1,903 — 795 1,615 — — 9,674 Substandard — 3,964 — — 2,571 292 — — 6,827 SBA secured by real estate Pass 113 9,334 7,634 1,979 4,109 22,417 — — 45,586 Special mention — 536 — — — 83 — — 619 Substandard — — — — — 4,536 — — 4,536 Total loans secured by business real estate 31,465 632,163 797,090 257,990 243,137 583,825 919 — 2,546,589 Current period gross charge-offs — — 318 191 — 1,861 — — 2,370 Commercial loans Commercial and industrial Pass 46,765 172,987 160,275 40,988 110,526 146,310 966,733 6,518 1,651,102 Special mention 239 23,242 12,270 367 16 2,139 42,570 407 81,250 Substandard 425 8,052 2,689 588 173 1,138 26,462 14,187 53,714 Doubtful and loss — — — — — — — 4,542 4,542 Franchise non-real estate secured Pass 6,801 74,441 112,112 16,355 34,770 53,957 — 753 299,189 Special mention 433 845 1,633 — 627 692 — — 4,230 Substandard — 1,646 322 2,324 10,451 1,559 — — 16,302 Term Loans by Vintage (Dollars in thousands) 2023 2022 2021 2020 2019 Prior Revolving Revolving Converted to Term During the Period Total December 31, 2023 SBA non-real estate secured Pass 1,075 4,485 343 113 1,464 2,490 — — 9,970 Substandard — 527 — 141 53 235 — — 956 Total commercial loans 55,738 286,225 289,644 60,876 158,080 208,520 1,035,765 26,407 2,121,255 Current period gross charge-offs 132 3,053 62 5 362 37 6,387 503 10,541 Retail loans Single family residential Pass 20 — — 167 — 44,104 28,461 — 72,752 Consumer loans Pass — — 3 9 5 788 1,144 — 1,949 Total retail loans 20 — 3 176 5 44,892 29,605 — 74,701 Current period gross charge-offs — — — — — 983 3 — 986 Loans held for investment before basis adjustment (1) $ 397,723 $ 2,905,140 $ 3,742,197 $ 1,239,280 $ 1,546,480 $ 2,395,055 $ 1,066,289 $ 26,407 $ 13,318,571 Total current period gross charge-offs $ 132 $ 3,053 $ 597 $ 196 $ 1,944 $ 6,534 $ 6,390 $ 503 $ 19,349 ______________________________ (1) Excludes the basis adjustment of $29.6 million to the carrying amount of certain loans included in fair value hedging relationships.

Refer to Note 19 – Derivative Instruments for additional information. Individually Evaluated Loans The Company evaluates loans collectively for purposes of determining the ACL in accordance with ASC 326. Collective evaluation is based on aggregating loans deemed to possess similar risk characteristics. In certain instances, the Company may identify loans that it believes no longer possess risk characteristics similar to other loans in the loan portfolio. These loans are typically identified from a substandard or worse internal risk grade, since the specific attributes and risks associated with such loans tend to become unique as the credit deteriorates. Such loans are typically nonperforming, modified loans made to borrowers experiencing financial difficulty, and/or are deemed collateral dependent, where the ultimate repayment of the loan is expected to come from the operation of or eventual sale of the collateral. Loans that are deemed by management to no longer possess risk characteristics similar to other loans in the portfolio are evaluated individually for purposes of determining an appropriate lifetime ACL. The Company uses a discounted cash flow approach, using the loan’s effective interest rate, for determining the ACL on individually evaluated loans, unless the loan is deemed collateral dependent, which requires evaluation based on the estimated fair value of the underlying collateral, less estimated costs to sell. The Company may increase or decrease the ACL for collateral dependent individually evaluated loans based on changes in the estimated expected 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, 2023, $24.8 million of loans were individually evaluated, with no ACL attributed to such loans. At December 31, 2023, $12.2 million of individually evaluated loans were evaluated based on the underlying value of the collateral and $12.6 million were evaluated using a discounted cash flow approach. All individually evaluated loans were on nonaccrual status at December 31, 2023. As of December 31, 2022, $30.9 million of loans were individually evaluated, and the ACL attributed to such loans totaled $1.7 million. At December 31, 2022, all of the individually evaluated loans were evaluated based on the underlying value of the collateral, and none were evaluated using a discounted cash flow approach. All individually evaluated loans were on nonaccrual status at December 31, 2022. Purchased Credit Deteriorated Loans 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 PCD loans of $359.3 million and $422.7 million at December 31, 2023 and 2022, respectively. 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. Collateral Dependent Loans Loans that have been classified as collateral dependent are loans where substantially all repayment of the loan is expected to come from the operation of or eventual liquidation of the collateral. Collateral dependent loans are evaluated individually for purposes of determining the ACL, which is determined based on the estimated fair value of the collateral. Estimates for costs to sell are included in the determination of the ACL when liquidation of the collateral is anticipated. In cases where the loan is well secured and the estimated value of the collateral exceeds the amortized cost of the loan, no ACL is recorded.

Provision for Loan and Lease Losses [Abstract]
Allowance for Credit Losses	Note 5 – Allowance for Credit Losses 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 initially recognize estimates for lifetime credit losses on loans and unfunded loan commitments at the time of origination or acquisition. The recognition of credit losses 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 Company’s ACL 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 PD, (ii) the estimated 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”). The PD and LGD are 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 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 secured by real estate and commercial loans is based on an internally developed PD rating scale that assigns PDs based on the Company’s internal credit risk grades for loans. This internally developed PD rating scale is based on a combination of the Company’s own historical data and observed historical data from the Company’s peers, which consist of banks that management believes align with our business profile. As credit risk grades change for 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 (“LTV”), estimated time to resolution, property size, and current and estimated future market price changes for underlying collateral. The LGD is highly dependent upon LTV 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 Consumer Price Index. 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 In order to develop reasonable and supportable forecasts of future conditions, the Company estimates 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 macroeconomic scenarios from an independent third party. These scenarios are based on past events, current conditions, and the likelihood of future events occurring. These scenarios typically are comprised of: a base-case scenario, an upside scenario, representing slightly better economic conditions than currently experienced and, a downside scenario, representing recessionary conditions. Management periodically evaluates appropriateness of economic scenarios and may decide that a particular economic scenario or a combination of probability-weighted economic scenarios should be used in the Company’s ACL model. The economic 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 likelihood that the economy would perform better than each scenario, 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. The Company’s ACL model at December 31, 2023 includes assumptions concerning the interest rate environment, general uncertainty concerning future economic conditions, and the potential for recessionary conditions. The Company 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 their long-term averages. The Company has reflected this reversion over a period of three years in each of its economic scenarios used to generate the overall probability-weighted forecast. Changes in economic forecasts impact the PD, LGD, and EAD for each loan, and therefore influence the amount of future cash flows the Company does not expect to collect for each loan. It is important to note that the Company’s ACL model relies on multiple economic variables, which are used in 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. These key economic variables include changes in the U.S. unemployment rate, U.S. real GDP growth, CRE prices, and interest rates. 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, considers the need for qualitative adjustments to the ACL on a quarterly basis. Qualitative adjustments may be related to and include, but not be limited to, factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios, and changes in portfolio segmentation, and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. As of December 31, 2023, qualitative adjustments primarily relate to certain segments of the loan portfolio deemed by management to be of a higher-risk profile or other factors where management believes the quantitative component of the Company’s ACL model may not be fully reflective of levels deemed adequate in the judgement of management. Certain qualitative adjustments also relate to heightened uncertainty as to future macroeconomic conditions and the related impact on certain loan segments. Management reviews the need for an 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, 2023 (Dollars in thousands) Beginning ACL Balance Charge-offs Recoveries Provision for Credit Losses Ending Investor loans secured by real estate CRE non-owner-occupied $ 33,692 $ (3,472) $ 159 $ 651 $ 31,030 Multifamily 56,334 (1,872) 1 1,849 56,312 Construction and land 7,114 — — 2,200 9,314 SBA secured by real estate 2,592 (108) — (302) 2,182 Business loans secured by real estate CRE owner-occupied 32,340 (2,370) 40 (1,223) 28,787 Franchise real estate secured 7,019 — — 480 7,499 SBA secured by real estate 4,348 — 248 (169) 4,427 Commercial loans Commercial and industrial 35,169 (10,474) 1,041 10,956 36,692 Franchise non-real estate secured 16,029 — 150 (1,048) 15,131 SBA non-real estate secured 441 (67) 71 13 458 Retail loans Single family residential 352 (90) 1 242 505 Consumer loans 221 (896) 35 774 134 Totals $ 195,651 $ (19,349) $ 1,746 $ 14,423 $ 192,471 For the Year Ended December 31, 2022 (Dollars in thousands) Beginning ACL Balance Charge-offs Recoveries Provision for Credit Losses Ending Investor loans secured by real estate CRE non-owner-occupied $ 37,380 $ (4,760) $ — $ 1,072 $ 33,692 Multifamily 55,209 — — 1,125 56,334 Construction and land 5,211 — — 1,903 7,114 SBA secured by real estate 3,201 (70) — (539) 2,592 Business loans secured by real estate CRE owner-occupied 29,575 — 56 2,709 32,340 Franchise real estate secured 7,985 — — (966) 7,019 SBA secured by real estate 4,866 — — (518) 4,348 Commercial loans Commercial and industrial 38,136 (8,387) 2,904 2,516 35,169 Franchise non-real estate secured 15,084 (448) — 1,393 16,029 SBA non-real estate secured 565 (50) 51 (125) 441 Retail loans Single family residential 255 — 148 (51) 352 Consumer loans 285 (4) — (60) 221 Totals $ 197,752 $ (13,719) $ 3,159 $ 8,459 $ 195,651 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 The decrease in the ACL for loans held for investment during 2023 of $3.2 million was reflective of $17.6 million in net charge-offs, partially offset by $14.4 million in provision for credit losses. The provision for credit losses in 2023 was largely impacted by changes in economic forecasts, slightly higher loss rates, and changes in qualitative adjustments, partially offset by lower loans held for investment. Charge-offs during 2023 were largely attributed to two C&I lending relationships, two CRE non-owner-occupied lending relationships, one CRE owner-occupied lending relationship, and one multifamily lending relationship. The decrease in the ACL for loans held for investment during 2022 of $2.1 million was reflective of $10.6 million in net charge-offs, partially offset by $8.5 million in provision for credit losses. The provision for credit losses in 2022 was largely impacted by changes to the overall size, composition, and asset quality trends of the loan portfolio. Charge-offs during 2022 were largely attributed to one C&I lending relationship and two CRE non-owner-occupied lending relationships. Allowance for Credit Losses for Off-Balance Sheet Commitments The Company maintains an ACL for off-balance sheet commitments related to unfunded loans and lines of credit, which is included in other liabilities of the consolidated statements of financial position. The allowance for off-balance sheet commitments was $19.3 million and $23.6 million at December 31, 2023 and 2022, respectively. The decline in the allowance for off-balance sheet commitments in 2023 is attributed to a provision recapture for off-balance sheet commitments of $4.4 million, which was primarily related to a decrease in the balance of unfunded commitments, changes in the mix of unfunded commitments between various loan segments, as well as qualitative adjustments during 2023. The ACL for off-balance sheet commitments was $23.6 million and $27.3 million at December 31, 2022 and 2021, respectively. The decline in the allowance for off-balance sheet commitments in 2022 was attributed to a provision recapture of $3.6 million, which was related primarily to changes in the mix of unfunded commitments between various loan segments, as well as qualitative adjustments during 2022. The following table summarizes the activities in the ACL for off-balance sheet commitments for the periods indicated: Year Ended December 31, (Dollars in thousands) 2023 2022 2021 Beginning ACL balance $ 23,641 $ 27,290 $ 31,118 Provision for credit losses on off-balance sheet commitments (4,377) (3,649) (3,828) Ending ACL balance $ 19,264 $ 23,641 $ 27,290

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Note 7 – Goodwill and Other Intangible Assets The Company had goodwill of $901.3 million at December 31, 2023 and 2022. The Company did not record any adjustments to goodwill in 2023 and 2022. 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. Due to the market volatility experienced in the banking sector during 2023, the Company made an unconditional election to bypass a qualitative assessment of goodwill and proceed directly to a quantitative assessment of goodwill in accordance with the guidance in ASC 350-20, Intangibles - Goodwill and Other - Goodwill during the fourth quarter of 2023. The quantitative assessment was performed with the assistance of an independent third party, and the results of this assessment indicated goodwill were not impaired as of December 31, 2023. Other intangible assets with definite lives were $43.3 million at December 31, 2023, consisting of $41.2 million in core deposit intangibles and $2.1 million in customer relationship intangibles. At December 31, 2022, the Company had other intangible assets of $55.6 million, consisting of $53.2 million in core deposit intangibles and $2.4 million in customer relationship intangibles.

Federal Home Loan Banks [Abstract]
Investments in Qualified Affordable Housing Partnerships	Note 9 – 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, 2023 and 2022 the carrying value of these investments was $88.8 million and $71.9 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, 2023 and 2022 the carrying value of these investments was $250,000 and $1.0 million, respectively. The Company’s net investment in qualified affordable housing projects that generate LIHTC and other tax benefits at December 31, 2023 and 2022 was $89.1 million and $72.9 million, respectively, and is recorded in other assets in the consolidated statements of financial condition. The total unfunded commitments related to the investments in qualified affordable housing partnerships totaled $32.1 million and $15.4 million at December 31, 2023 and 2022, respectively, and were recorded in accrued expenses and other liabilities. As of December 31, 2023, the Company’s unfunded affordable housing partnerships commitments were estimated to be paid as follows: (Dollars in thousands) Amount Year Ending December 31, 2024 $ 11,065 2025 11,840 2026 3,892 2027 2,458 2028 439 Thereafter 2,376 Total unfunded commitments $ 32,070 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, 2023, 2022, and 2021.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 10 – Variable Interest Entities The Company is involved with VIEs through its loan securitization activities and affordable housing investments that qualify for the low-income housing tax credit,. The Company has determined that its interests in these entities meet the definition of variable interests. As of December 31, 2023 and December 31, 2022, 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 exposure to loss as of December 31, 2023 and December 31, 2022 that relate to variable interests in non-consolidated VIEs.

(2) Included in accrued expenses and other liabilities on the consolidated statements of financial condition. (3) Included in other assets on the consolidated statements 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 underlying Freddie Mac-issued guaranteed, structured pass-through certificates that were held as AFS investment securities at fair value as of December 31, 2023. 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. During 2023, as the total outstanding principal amount of the underlying loans decreased below the aforementioned reimbursement threshold, the maximum exposure was the total outstanding principal amount of the underlying loans of $48.0 million at December 31, 2023. Based upon our analysis of quantitative and qualitative data over the underlying loans included in the securitization pool, as of December 31, 2023 and 2022, our reserve for estimated losses with respect to the reimbursement obligation was $345,000 and $334,000, 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 the ability to exercise significant influence over or participate in the decision-making activities related to the management of 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 associated with the affordable housing partnership investments is recorded as 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, 2023 and 2022, respectively.

Debt Disclosure [Abstract]
Subordinated Debentures	Note 13 – Subordinated Debentures As of December 31, 2023, the Company had three subordinated notes with an aggregate carrying value of $331.8 million and a weighted interest rate of 5.31%, compared to $331.2 million with a weighted interest rate of 5.32% at December 31, 2022. The increase of $638,000 was primarily due to amortization of debt issuance costs. 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 Notes I bear interest at an annual fixed rate of 5.75%, with the first interest payment on the Notes I made on March 3, 2015, and interest payable semiannually each March 3 and September 3 through September 3, 2024. At December 31, 2023, the carrying value of the Notes I was $59.9 million, net of unamortized debt issuance costs of $90,000. The Notes I 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, 2023, the Notes I did not qualify as Tier 2 Capital as the remaining maturity is less than one year 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. Upon the cessation of LIBOR on June 30, 2023, the original 3-month LIBOR-based floating benchmark rate plus a spread of 2.5% after May 15, 2024 for the Notes II transitioned to 3-month term SOFR as successor base rate plus a spread of 2.762% 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, 2023, the Notes II qualify as Tier 2 Capital. At December 31, 2023, the carrying value of the Notes II was $123.6 million, net of unamortized debt issuance cost of $1.4 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 3-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, 2023, the Notes III qualified as Tier 2 capital. At December 31, 2023, the carrying value of the Notes III was $148.3 million, net of unamortized debt issuance cost of $1.7 million. In connection with the various issuances of subordinated notes, 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 and senior unsecured debt rating of A- and subordinated debt rating of BBB+ for the Bank. The Corporation’s and Bank’s ratings were reaffirmed in June 2023 by KBRA.

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, 2023 and 2022. As of December 31, 2023, the Company had federal and state net operating loss carryforwards of approximately $35.9 million and $4.8 million, respectively. The federal and state net operating losses of $20.9 million and $4.8 million will begin to expire in 2026 and 2029, respectively, unless previously utilized. Approximately $15.0 million of the federal net operating losses can be carried forward indefinitely. In addition, the Company has a tax credit carryforward of $156,000, which is scheduled to expire by 2040. Under Section 382 of the Code, annual use of our net operating losses and tax credits may be limited if a cumulative change in ownership of more than 50% occurs within a three-year period. Except for the $15.0 million federal net operating losses, the Company’s federal and state net operating losses and tax credits are subject to the limitation under Section 382. The Company is expected to fully utilize the federal and state net operating losses and tax credits before expiration 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 2019. 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 major 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) 2023 2022 Balance at January 1, $ 1,437 $ 1,437 Increases based on tax positions related to prior years — — Decreases related to settlements with taxing authorities — — Decreases related to lapse of statute of limitation — — Balance at December 31, $ 1,437 $ 1,437 The total amount of unrecognized tax benefits was $1.4 million at December 31, 2023 and 2022, 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 at December 31, 2023 and 2022. It is reasonably possible that $1.1 million of the Company's unrecognized tax benefits may be recognized within the next 12 months due to a lapse of the statute of limitations. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The Company has accrued $200,000 and $89,000 for such interest at December 31, 2023 and 2022, respectively. No amounts for penalties were accrued at December 31, 2023 and 2022.

Commitments and Contingencies Disclosure [Abstract]
Off-Balance Sheet Arrangements, Commitments, and Contingencies	Note 15 – 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) 2023 2022 Loan commitments to extend credit $ 1,655,078 $ 2,443,791 Standby letters of credit 48,392 45,412 Total $ 1,703,470 $ 2,489,203 The balance at December 31, 2023 is primarily composed of $1.43 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 $19.3 million and $23.6 million at December 31, 2023 and 2022, respectively. 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, 2023 and 2022, LIHTC commitments totaled $32.1 million and $15.4 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 $16.92 billion and $17.08 billion at December 31, 2023 and 2022, respectively. Legal Proceedings

There was no compensation expense related to stock options for the years ended December 31, 2023, 2022, and 2021. At December 31, 2023, there was no unrecognized compensation expense related to the options. Restricted Stock Awards Below is a summary of the activity for restricted stock and restricted stock units in the Plans for the year ended December 31, 2023: 2023 Shares Weighted Average Grant-Date Fair Value Per Share Unvested at the beginning of the year 1,204,970 $ 35.43 Granted 974,840 24.22 Vested (454,563) 32.77 Forfeited (149,351) 31.67 Unvested at the end of the year 1,575,896 $ 29.62 The total grant date fair value of awards was $23.6 million for 2023 awards. At December 31, 2023, unrecognized compensation expense related to restricted stock awards is approximately $34.3 million, which is expected to be recognized over a weighted-average period of 2.53 years. Restricted Stock Units Below is a summary of the activity for restricted stock units in the Plans for the year ended December 31, 2023: 2023 Shares Weighted Average Grant-Date Fair Value Per Share Unvested at the beginning of the year 401,476 $ 32.11 Granted 217,014 21.20 Vested (212,013) 18.30 Forfeited (6,681) 17.48 Unvested at the end of the year 399,796 $ 35.04 The total grant date fair value of awards was $3.8 million for 2023 awards.

Restricted stock awards and restricted stock units with a service condition for vesting are valued at the closing stock price on the date of grant and are expensed to stock-based compensation expense ratably under the straight-line attribution method over the requisite service period. Restricted stock units with a performance condition for vesting are valued at the closing stock price on the date of grant and the expense is estimated based on the share percentage payout expected to be achieved at vesting over a three-year performance period. The Company evaluates the probable outcome of the performance conditions quarterly and makes cumulative adjustments for current and prior periods in compensation expense in the period of change. Restricted stock units with a market condition for vesting are valued using a Monte Carlo valuation model and are expensed to stock-based compensation expense over a three-year performance period. The previously recognized compensation expense for awards with a market condition will reverse only if the requisite service is not rendered. For accounting on stock-based compensation plans, see Note 1 – Description of Business and Summary of Significant Accounting Policies for more information. Other Plans Salary Continuation Plan.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	12 Months Ended
Fair Value of Financial Instruments	Dec. 31, 2023
Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 17 – 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 - Financial Instruments 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 ASC Topic 820 - Fair Value Measurement , 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. AFS 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. Equity Securities With Readily Determinable Fair Values – The Company’s equity securities with readily determinable fair values consist of investments in public companies and qualify for CRA purposes. The fair value is based on the closing price on nationally recognized securities exchanges at the end of each period and classified as Level 1 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 - Derivatives and Hedging . 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. Foreign Exchange Contracts – The Company enters into foreign exchange contracts to accommodate the business needs of its customers.

Individually evaluated loans are measured at fair value when they are deemed collateral dependent. Fair value on such loans is measured based on the underlying collateral. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate, and cash. The Company measures impairment on all individually evaluated loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. Other Real Estate Owned – OREO is initially recorded at the fair value less estimated costs to sell at the date of transfer. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the allowance for credit losses. The fair value of individually evaluated collateral dependent loans and OREO 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 and OREO, the Company then discounts 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, 2023, 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 recorded the related reserves where applicable during the year ended December 31, 2023.

Earnings Per Share [Abstract]
Earnings Per Share	Note 18 – 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) 2023 2022 2021 Basic Net income $ 30,852 $ 283,743 $ 339,889 Less: dividends and undistributed earnings allocated to participating securities (2,061) (3,405) (3,517) Net income allocated to common stockholders $ 28,791 $ 280,338 $ 336,372 Weighted average common shares outstanding 94,113,132 93,718,293 93,532,109 Basic earnings per common share $ 0.31 $ 2.99 $ 3.60 Diluted Net income allocated to common stockholders $ 28,791 $ 280,338 $ 336,372 Weighted average common shares outstanding 94,113,132 93,718,293 93,532,109 Dilutive effect of share-based compensation 123,743 373,168 480,028 Weighted average diluted common shares 94,236,875 94,091,461 94,012,137 Diluted earnings per common share $ 0.31 $ 2.98 $ 3.58 Shares or stock options are excluded from the computations of diluted earnings per share when their inclusion have an anti-dilutive effect. The dilutive impact of these securities could be included in future computations of diluted earnings per share if the market price of the common stock increases. For the year ended December 31, 2023, there were 71,447 weighted average potential common shares that were anti-dilutive. There were no potential common shares that were anti-dilutive at December 31, 2022 and December 31, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Note 19 – 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. The Company entered into pay-fixed and receive-floating interest rate swaps associated with certain fixed rate loans, primarily commercial real estate and multifamily loans, to manage its exposure to changes in fair value on these instruments attributable to changes in the designated SOFR benchmark interest rate. These interest rate swaps are designated as fair value hedges using the portfolio layer method. 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 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, 2023 and December 31, 2022, interest rate swaps with an aggregate notional amount of $1.35 billion and $1.20 billion, respectively, were designated as fair value hedges. Cash flows on derivatives designated as hedging instruments are classified in the statement of cash flows the same as the cash flows of the assets being hedged. The following amounts were recorded on the consolidated statements 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, 2023 December 31, 2022 December 31, 2023 December 31, 2022 Loans held for investment (1) $ 1,320,449 $ 1,138,074 $ (29,551) $ (61,926) Total $ 1,320,449 $ 1,138,074 $ (29,551) $ (61,926) ______________________________ (1) These amounts were included in the amortized cost basis of closed portfolios of loans held for investment used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. At December 31, 2023 and December 31, 2022 , the amortized cost basis of the closed portfolios used in these hedging relationships was $3.25 billion and 3.35 billion, respectively; the cumulative basis adjustments associated with these hedging relationships was $(29.6) million and $(61.9) million, respectively; and the amounts of the designated hedged items were $1.35 billion and $1.20 billion, respectively. 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 offsetting 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 values of these agreements are determined through a third-party valuation model used by the Company’s swap advisory firm, which uses observable market data such as interest rates, prices of Eurodollar futures 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 statements of financial condition. 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. Upon the cessation of LIBOR on June 30, 2023, our LIBOR-indexed interest rate swap contracts transitioned to SOFR as successor rate for both valuations and settlements. 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. Foreign Exchange Contracts – The Company offers foreign exchange spot and forward contracts as accommodations to its customers to purchase and/or sell foreign currencies at a contractual price. In conjunction with these products the Company also enters into offsetting contracts with institutional counterparties to mitigate the Company’s foreign exchange exposure with its customers, or enters into bilateral collateral and master netting agreements with certain customer counterparties to manage its credit exposure. These contracts allow the Company to offer its customers foreign exchange products while minimizing its exposure to foreign exchange rate fluctuations. These foreign exchange contracts are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities in the Company’s consolidated statements of financial condition. Changes in the fair value of these contracts are recorded in the Company’s consolidated statements of income as a component of noninterest income. 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 zero and $1.9 million in other assets as of December 31, 2023 and 2022, respectively. During 2023, the equity warrant assets were either settled or written off as the warrants were determined to be unexercisable until the underlying company’s fair market value is greater than the value established in the warrant agreement. The net increases or decreases in derivatives not designated as hedging instruments are included in “Net change in accrued interest receivable and other assets” and “Net change in accrued expenses and other liabilities” within the statement of cash flows.

Offsetting [Abstract]
Balance Sheet Offsetting	Note 20 – Balance Sheet Offsetting Derivative financial instruments may be eligible for offset in the consolidated statements of financial condition, 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. 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. The gross amounts of derivative assets and liabilities for derivative contracts cleared through certain central clearing parties are reported at the fair value of the respective derivative contracts net of the variation margin payments, where applicable. 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 Statements of Financial Condition (Dollars in thousands) Gross Amounts Recognized (1) Gross Amounts Offset in the Consolidated Statements of Financial Condition Net Amounts Presented in the Consolidated Statements of Financial Condition Financial Instruments (2) Cash Collateral (3) Net Amount December 31, 2023 Derivative assets: Interest rate swaps $ 5,643 $ — $ 5,643 $ — $ (4,610) $ 1,033 Total $ 5,643 $ — $ 5,643 $ — $ (4,610) $ 1,033 Financial liabilities: Interest rate swaps $ 10,705 $ — $ 10,705 $ — $ — $ 10,705 Total $ 10,705 $ — $ 10,705 $ — $ — $ 10,705 December 31, 2022 Derivative assets: Interest rate swaps $ 7,053 $ — $ 7,053 $ — $ (5,440) $ 1,613 Total $ 7,053 $ — $ 7,053 $ — $ (5440) $ 1,613 Financial liabilities: Interest rate swaps $ 12,530 $ — $ 12,530 $ — $ — $ 12,530 Total $ 12,530 $ — $ 12,530 $ — $ — $ 12,530 ______________________________ (1) Represents amounts after the application of variation margin payments as settlements with central counterparties, where applicable.

Leases [Abstract]
Leases	Note 21 – 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 statements of financial condition. At December 31, 2023, 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 on the related liability to make future lease payments.

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, 2023, the Company had 58 full-service depository branches located in the Western Region of the U.S. in major metropolitan markets in Arizona, California, Nevada, and Washington. The Company also offers IRA custodial and maintenance services through its Pacific Premier Trust division, which serves as a custodian for self-directed IRAs as well as certain accounts that do not qualify as IRAs pursuant to the Internal Revenue Code. Account owners use the funds for self-directed investments in various alternative asset classes. Additionally, the Company provides commercial escrow and exchange services through its Commerce Escrow division, which facilitates commercial escrow services and tax-deferred commercial real estate exchanges under Section 1031 of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). The Company is also 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 U.S. (“GAAP”). Certain amounts in the consolidated financial statements and the related footnote disclosure for the prior periods have been reclassified to conform to the current presentation. Reclassifications had no effect on net income or stockholders’ equity as previously reported.
Use of Estimates	Use of Estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash and cash equivalents include cash on hand, cash balances due from banks, federal funds sold and cash items in the process of collection. Interest-bearing deposits with financial institutions primarily represent 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, 2023, 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 securities as either held-to-maturity or available-for-sale, or held-for-trading based on the Company’s investment objectives, operational needs, and intent. 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 (“HTM”). Investments in debt securities that management has the positive intent and ability to hold to maturity are reported at amortized cost. The amortization of premiums and accretion of discounts are recognized in interest income using the interest method over the period of time remaining to an 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 (loss) 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 (“AFS”). 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 first 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 accumulated other comprehensive income (loss). 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 (loss) on investment securities.
Allowance for Credit Losses on Investment Securities	Allowance for Credit Losses (“ACL”) on Investment Securities. The ACL on investment securities is determined for both the HTM and AFS classifications of the investment portfolio in accordance with ASC 326 on a quarterly basis. The ACL for HTM 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 of the consolidated statements of financial condition. The ACL for HTM 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 risk characteristics similar with others in the portfolio. For investment securities where the Company has reason to believe the credit loss exposure is remote, a zero credit loss assumption is applied. Such investment securities typically consist of those guaranteed by the U.S. government or other government enterprises, where there is an explicit or implicit guarantee by the U.S. government, that are highly rated by rating agencies, and historically have had no credit loss experience. For AFS 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, in accumulated other comprehensive income (loss). The Company determines the amount of expected credit losses on AFS and HTM securities through a discounted cash flow approach, using the security’s effective interest rate. 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 AFS 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. Dividends received on equity securities are included in interest income on investment securities and other interest earning assets in the consolidated statements of income. 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 3-5% or when the Company has the ability to exercise significant influence over the entity. Such investments typically reflect equity interests in various partnerships that make investments qualifying for credit under the Community Reinvestment Act (“CRA”) and are recorded in other assets of the consolidated statements of financial condition. 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. Ownership of FHLB stock is restricted to member banks and is not actively traded on an exchange. 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.
Loans Held for Sale	Loans Held for Sale. Loans for which the Company does not have the intent or ability to hold for the foreseeable future are designated as held for sale at their 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 determination of the gain or loss on the sale of the loan.
Loan Servicing Assets	Loan Servicing Assets. Servicing assets are related to U.S. Small Business Administration (“SBA”) loans sold and are recognized at the time of sale when servicing is retained with the income statement effect recorded in net gain on sales of 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 for the foreseeable future, or 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 contractual life of the loans. Accretion or amortization of deferred loan fees and costs or discounts and premiums 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 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 the 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 (“CRE”) non-owner-occupied - 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 - 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. government. 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”) - C&I loans are loans that are 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 Homeowners’ Association (“HOA”) credit facilities are included in C&I loans. We also issue letters of credit on behalf of our customers. Risk associated with C&I 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 them through bank acquisitions. We originate home equity lines of credit loans to consumers within our market area. 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 to banking clients. Our consumer loans consist primarily of small balance personal unsecured loans and savings account secured 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. The Company has loans it has previously acquired through purchase or business combinations. When loans are purchased or acquired 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 methodology for determining the ACL. The ACL for non-PCD loans is recorded through a charge to the provision for credit losses in the period in which the loans were purchased or acquired.
Allowance for Credit Losses on Loans	Allowance for Credit Losses on Loans. The Company accounts for credit losses on loans in accordance with ASC 326, which requires the Company to record an estimate of expected lifetime credit losses for loans at the time of origination or acquisition. The ACL is maintained at a level deemed appropriate by management to provide for expected credit losses in the portfolio as of the date of the consolidated statements of financial condition. Estimating expected credit losses requires management to use relevant forward-looking information, including the use of reasonable and supportable forecasts. The measurement of the ACL is performed by collectively evaluating loans with similar risk characteristics. The Company measures the ACL on commercial real estate loans and commercial loans using a discounted cash flow approach, and a historical loss rate methodology is used to determine the ACL on retail loans. The Company’s discounted cash flow methodology incorporates a probability of default (“PD”) and loss given default (“LGD”) model, whereby PDs and LGDs are forecasted using economic scenarios over a two-year period to generate estimates for cash flows expected to be collected over the estimated life of a loan. Beyond the two-year forecast time horizon, the Company’s ACL model reverts to historical long-term average loss rates over a period of three years. 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 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. Expectations of future cash flows are discounted at the loan’s effective interest rate. The Company has made an accounting policy election to adjust the effective interest rate to take into consideration the effects of estimated prepayments. 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. 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 provide a sufficient basis for determining future expected credit losses. 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 credit risk grade, and may consist of loans on nonaccrual status, modified loans to troubled borrowers, 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 based on the estimated expected 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 and may require changes to the ACL. Please also see Note 5 – Allowance for Credit Losses for additional discussion concerning the Company’s ACL methodology, including discussion concerning economic forecasts used in the determination of the ACL.
Modified Loans to Borrowers Experiencing Financial Difficulty	Modified Loans to Borrowers Experiencing Financial Difficulty . Infrequently, the Company makes modifications to certain loans in order to alleviate temporary difficulties 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. The Company also refers to these modifications as modified loans to troubled borrowers (“MLTB”). Modifications may include: changes in the amortization terms of the loan, reductions in interest rates, acceptance of interest only payments, and, in very limited cases, reductions to the outstanding loan balance. Such loans are typically placed on nonaccrual status when there is doubt concerning the full repayment of principal and interest or the loan has been in default for a period of 90 days or more. Such loans may be 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 on MLTB on an individual basis when such loans are deemed to no longer share risk characteristics that are similar with other loans in the portfolio. The determination of the ACL for these loans 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 estimated expected fair value of the underlying collateral, less costs to sell. GAAP requires the Company to make certain disclosures related to these loans, including certain types of modifications, as well as how such loans have performed since their modifications. Please see Note 4 – Loans Held for Investment for additional information concerning modified loans to troubled borrowers.
Loan Commitments and Related Financial Instruments	Off-balance Sheet Commitments. Such commitments consist of 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. The Company records an ACL for off-balance sheet lending commitments using the same models and methodologies previously discussed under Allowance for Credit Losses on Loans , while incorporating assumptions for utilization. Please also see Note 5 - Allowance for Credit Losses for additional discussion concerning the ACL for off-balance sheet commitments.
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 over the fair value of the property recorded as a charge against the ACL at the time of foreclosure. The Company obtains an appraisal and/or market valuation on all other real estate owned upon foreclosure. 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, including leasehold improvements, 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 assets are recorded at their cash surrender value. 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 originates 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. Goodwill has an indefinite useful life and is not amortized, but tested for impairment at least annually or more frequently if events and circumstances lead management to believe the value of goodwill 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, 2023. Management’s assessment of goodwill is performed in accordance with ASC 350-20, Intangibles - 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 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 is below its carrying value, the Company then performs the quantitative assessment of goodwill to determine the fair value of the Company and compares the results of that assessment to the carrying value of the Company. If the fair value of the Company is below its carrying value, a goodwill impairment loss would be recognized for the amount by which the Company’s carrying value exceeds its fair value. Impairment losses are recorded as a charge to noninterest expense. The Company’s annual impairment test of goodwill is performed in the fourth quarter of each year. The Company elected to perform a quantitative assessment of goodwill for its 2023 annual impairment test, the results of which indicated the value of goodwill was not impaired. As of December 31, 2023, 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 on a straight-line basis over their estimated useful lives, which ranges from six such assets 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 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. The Company has derivative instruments designated as part of fair value accounting hedges. These derivatives consist of pay-fixed, receive-floating interest rate swaps, and were entered into to hedge changes in the fair value of fixed-rate assets for specific risks, such as interest rate risk resulting from changes in a benchmark interest rate. In a qualifying fair value hedge, the Company records periodic changes in the fair value of the derivative instrument in current period earnings. Simultaneously, periodic changes in the fair value of the hedged risk are also recorded in current period earnings. Together, these periodic changes in the fair value of the derivative instrument and the fair value of the hedged risk are included in the same line item of the statements of income associated with the hedged item (i.e. interest income), and largely offset each other. Interest accruals on both the derivative instrument and the hedged item are also recorded in the same line item, which effectively converts the designated fixed-rate assets to floating-rate assets. The Company structures these interest rate swaps to match the critical terms of the hedged items (i.e. fixed-rate loans), thereby maximizing the economic and accounting effectiveness of the hedging relationships and resulting in the expectation that the hedging relationship will be highly effective. If a fair value hedging relationship ceases to qualify for hedge accounting, hedge accounting is discontinued and future changes in the fair value of the derivative instrument are recognized in current period earnings, until the derivative is settled with the counterparty. In addition, all remaining basis adjustments resulting from periodic changes in the fair value of the hedged risk, previously recorded as a component of the carrying amount of the hedged item, are amortized or accreted into interest income using the interest method over the remaining life of the hedged item.
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 fair value of the consideration paid for an acquired entity exceeds the estimated fair value of the net assets acquired. If, following the close of an acquisition, additional information is obtained concerning the acquisition date fair value estimates for assets acquired and liabilities assumed, GAAP allows for corresponding adjustments to be made to goodwill over a one year measurement period following the date of acquisition. 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, giving consideration for periodic contractual rent increases, which may be 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 on the lease liability. 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 and is included in premises and occupancy expense of the consolidated statements of income. Right-of-use assets are recorded in other assets and liabilities to make lease payments are recorded in accrued expenses and other liabilities of the consolidated statements of financial condition. As of December 31, 2023, 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 of the awards 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. The Company did not issue any stock option awards during 2023 or 2022. 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, 2023 and 2022, 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 share. 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 and the components of accumulated other comprehensive income (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 are any 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 - Financial Instruments 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 ASC Topic 820 - Fair Value Measurement , 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. AFS 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. Equity Securities With Readily Determinable Fair Values – The Company’s equity securities with readily determinable fair values consist of investments in public companies and qualify for CRA purposes. The fair value is based on the closing price on nationally recognized securities exchanges at the end of each period and classified as Level 1 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 - Derivatives and Hedging . 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. Foreign Exchange Contracts – The Company enters into foreign exchange contracts to accommodate the business needs of its customers. The Company also enters into offsetting contracts with institutional counterparties to mitigate the Company’s foreign exchange exposure with its customers, or enters into bilateral collateral and master netting agreements with certain customer counterparties to manage its credit exposure. The Company measures the fair value of foreign exchange contracts based on quoted prices for identical instruments in active markets, a Level 1 measurement. 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 at fair value when they are deemed collateral dependent. Fair value on such loans is measured based on the underlying collateral. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate, and cash. The Company measures impairment on all individually evaluated loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling cost. Other Real Estate Owned – OREO is initially recorded at the fair value less estimated costs to sell at the date of transfer. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the allowance for credit losses. The fair value of individually evaluated collateral dependent loans and OREO 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 and OREO, the Company then discounts 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 The Company is involved with VIEs through its loan securitization activities and affordable housing investments that qualify for the low-income housing tax credit,. The Company has determined that its interests in these entities meet the definition of variable interests.
Recent Accounting Guidance Not Yet Effective and Accounting Guidance Adopted in 2023	Recent Accounting Guidance Not Yet Effective In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures . The FASB issued this Update to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this Update address investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this Update are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this Update on its consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segments . The amendments in this Update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis. Amendments in this Update include: a requirement that a public entity provide all annual disclosures about a reportable segment’s profit or loss in its interim period disclosures, disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), disclosure of amounts for other segment items by reportable segment and a description of its composition, clarification that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit or loss, requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss, and requires that a public entity that has a single reportable segment provide all the disclosures required by this Update as well as all existing disclosures required in Topic 280. The amendments in this Update are effective for fiscal years beginning after December 15, 2023 and for interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this Update on its consolidated financial statements. In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, a consensus of the Emerging Issues Task Force . The amendments in this Update allow the option for an entity to apply the proportional amortization method of accounting to other equity investments that are made for the primary purpose of receiving income tax credits or other income tax benefits, if certain conditions are met. Prior to this Update, the application of the proportional amortization method of accounting was limited to investments in low income housing tax credit structures. The proportional amortization method of accounting results in the amortization of applicable investments, as well as the related income tax credits or other income tax benefits received, being presented on a single line in the statements of income, that is income tax expense. Under this Update, an entity has the option to apply the proportional amortization method of accounting to applicable investments on a tax-credit-program-by-tax-credit-program basis. In addition, the amendments in this Update require that all tax equity investments accounted for using the proportional amortization method use the delayed equity contribution guidance in paragraph 323-740-25-3, requiring a liability be recognized for delayed equity contributions that are unconditional and legally binding or for equity contributions that are contingent upon a future event when that contingent event becomes probable. Under this Update, low income housing tax credit investments for which the proportional amortization method is not applied can no longer be accounted for using the delayed equity contribution guidance. Further, this Update specifies that tax equity investments accounted for using the equity method must apply the impairment guidance in Subtopic 323-10 - Investments - Equity Method and Joint Ventures - Overall. This Update also clarifies that for low income housing tax credit investments not accounted for under the proportional amortization method or the equity method, an entity shall account for them under Topic 321 - Investments - Equity Securities. The amendments in this Update also require additional disclosures in interim and annual periods concerning investments for which the proportional amortization method is applied, including (i) the nature of tax equity investments, and (ii) the effect of tax equity investments and related income tax credits and other income tax benefits on the financial position and results of operations. The provisions of this Update are effective for the Company for interim and annual periods beginning after December 15, 2023. Early adoption is permitted. The Company has evaluated the provisions of this Update and does not believe they will have a material impact on the Company’s consolidated financial statements. Accounting Guidance Adopted in 2023 In March 2022, the FASB issued ASU 2022-02, Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures . The FASB issued this Update in response to feedback the FASB received from various stakeholders in its post-implementation review process related to the issuance of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which was effective for the Company on January 1, 2020. The amendments in this Update include the elimination of accounting guidance for troubled debt restructurings (“TDRs”) in Subtopic 310-40 - Receivables - Troubled Debt Restructurings by Creditors, and introduce new disclosures and enhance existing disclosures concerning certain loan refinancings and restructurings when a borrower is experiencing financial difficulty. Under the provisions of this Update, an entity must determine whether a modification results in a new loan or the continuation of an existing loan. Further, the amendments in this Update require that a public business entity disclose current period gross charge-offs on financing receivables within the scope of ASC 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost, by year of origination and class of financing receivable. The amendments in this Update became effective for the Company on January 1, 2023 for all interim and annual periods. The Company adopted the provisions in this Update prospectively. The adoption of the provisions of this have resulted in additional disclosures concerning modifications of loans to borrowers experiencing financial difficulty, as well as disaggregated disclosure of charge-offs on loans. Please also see Note 4 – Loans Held for Investment for added disclosure concerning modifications of loans to borrowers experiencing financial difficulty, as well as current period gross charge-offs on loans by year of origination and loan classification. In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815) Fair Value Hedging - Portfolio Layer Method . The amendments in this Update make targeted improvements to fair value hedge accounting and more specifically to the last-of-layer hedge accounting method. This Update expands the last-of-layer hedge accounting method to allow for multiple hedged layers to be designated for a single closed portfolio of prepayable financial assets, and renames this accounting method the “portfolio layer method.” The provisions of this Update also include: (i) expanding the scope of the portfolio layer method to nonprepayable financial assets, (ii) specifying that eligible hedging instruments in a single layer hedge may include spot-starting or forward-starting constant-notional or amortizing-notional swaps and that the number of hedged layers corresponds with the number of hedges designated, (iii) specifies that an entity hedging multiple amounts in a closed portfolio using a single amortizing-notional swap is executing a single-layer hedge, (iv) provides additional guidance on the accounting for and disclosure of hedge basis adjustments resulting from a fair value hedge under the portfolio layer method by requiring such basis adjustments be maintained at the portfolio level and not allocated to individual assets, and to disclose basis adjustments as a reconciling item in certain disclosures, such as those for loans, and (v) specifies that an entity is to exclude hedge basis adjustments in the determination of credit losses on the assets within the closed portfolio. The provisions of this Update became effective for the Company on January 1, 2023 for all interim and annual periods. The adoption of the provisions in this Update did not have a material impact on the Company’s consolidated financial statements. Please also see Note 19 – Derivative Instruments , for disclosure concerning the Company’s portfolio layer method fair value hedges. 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 become effective upon issuance for all entities. 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. The use of LIBOR was discontinued after June 30, 2023. In anticipation of this, the Company previously created a cross-functional working group to manage the transition away from LIBOR. This working group was 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 monitored developments related to transition and uncertainty surrounding reference rate reform and guided the Bank’s response. The working group performed regular assessments of the population of financial instruments that referenced LIBOR and worked to transition such instruments away from LIBOR. The working group also worked to confirm the Bank’s loan documents that referenced LIBOR have been appropriately amended, ensuring that our internal systems were prepared for the transition, and managed 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 may also use other alternative reference rates, such as the Constant Maturity Treasury index and Prime rate based on the individual needs of our customers as well as the types of credit being extended.
