Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Description of Business and Basis of Presentation TriCo Bancshares (the “Company” or “we”) is a California corporation organized to act as a bank holding company for Tri Counties Bank (the “Bank”). The Company and the Bank are headquartered in Chico, California. The Bank is a California-chartered bank that is engaged in the general commercial banking business in 31 California counties. The consolidated financial statements are prepared in accordance with accounting policies generally accepted in the United States of America and general practices in the banking industry. All adjustments necessary for a fair presentation of these consolidated financial statements have been included and are of a normal and recurring nature. The financial statements include the accounts of the Company. All inter-company accounts and transactions have been eliminated in consolidation. The Company has five capital subsidiary business trusts (collectively, the “Capital Trusts”) that issued trust preferred securities, including two organized by the Company and three acquired with the acquisition of North Valley Bancorp. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1,748,000 are accounted for under the equity method and, accordingly, are not consolidated and are included in other assets on the consolidated balance sheet. See the footnote 'Junior Subordinated Debt' for additional information on borrowings outstanding. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”). The Company believes that the disclosures made are adequate to make the information not misleading. Segment and Significant Group Concentration of Credit Risk The Company grants agribusiness, commercial, consumer, and residential loans to customers located throughout California. The Company has a diversified loan portfolio within the business segments located in this geographical area. The Company currently classifies all its operation into one business segment that it denotes as community banking. Geographical Descriptions For the purpose of describing the geographical location of the Company’s operations, the Company has defined northern California as that area of California north of, and including, Stockton to the east and San Jose to the west; central California as that area of the state south of Stockton and San Jose, to and including, Bakersfield to the east and San Luis Obispo to the west; and southern California as that area of the state south of Bakersfield and San Luis Obispo. Reclassification Some items in the prior year consolidated financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholders’ equity. Cash and Cash Equivalents Net cash flows are reported for loan and deposit transactions and other borrowings. For purposes of the consolidated statement of cash flows, cash, due from banks with original maturities less than 90 days, interest-earning deposits in other banks, and Federal funds sold are considered to be cash equivalents. Allowance for Credit Losses - Securities The Company measures expected credit losses on HTM debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on HTM debt securities totaled was considered insignificant at March 31, 2022 and is therefore excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current condition and reasonable and supportable forecasts based on current and expected changes in credit ratings and default rates. Based on the implied guarantees of the U. S. Government or its agencies related to certain of these investment securities, and the absence of any historical or expected losses, substantially all qualify for a zero loss assumption. Management has separately evaluated its HTM investment securities from obligations of state and political subdivisions utilizing the historical loss data represented by similar securities over a period of time spanning nearly 50 years. As a result of this evaluation, management determined that the expected credit losses associated with these securities is not significant for financial reporting purposes and therefore, no allowance for credit losses has been recognized. The Company evaluates AFS debt securities in an unrealized loss position to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized as an allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings. Both the allowance for credit losses and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available for sale debt security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount is recognized in earnings with a corresponding adjustment to the security's amortized cost basis. In evaluating available for sale debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers' financial condition, among other factors. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the ACL when management believes the uncollectability of an available for sale debt security is confirmed or when either of the criteria regarding intent or requirement to sell is met. No security credit losses were recognized during the three month periods ended March 31, 2022 and 2021, respectively. Loans Loans that management has the intent and ability to hold until maturity or payoff are reported at principle amount outstanding, net of deferred loan fees and costs. Loans are placed in nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal, or a loan becomes contractually past due by 90 days or more with respect to interest or principal and is not well secured and in the process of collection. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against interest income. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is considered probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of Management, the loan is estimated to be fully collectible as to both principal and interest. Accrued interest receivable is not included in the calculation of the allowance for credit losses. Allowance for Credit Losses - Loans The ACL is a valuation account that is deducted from the loan's amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the recorded loan balance is confirmed as uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Regardless of the determination that a charge-off is appropriate for financial accounting purposes, the Company manages its loan portfolio by continually monitoring, where possible, a borrower's ability to pay through the collection of financial information, delinquency status, borrower discussion and the encouragement to repay in accordance with the original contract or modified terms, if appropriate. Management estimates the allowance balance using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. Historical credit loss experience provides the basis for the estimation of expected credit losses, which captures loan balances as of a point in time to form a cohort, then tracks the respective losses generated by that cohort of loans over the remaining life. The Company identified and accumulated loan cohort historical loss data beginning with the fourth quarter of 2008 and through the current period. In situations where the Company's actual loss history was not statistically relevant, the loss history of peers, defined as financial institutions with assets greater than three billion and less than ten billion, were utilized to create a minimum loss rate. Adjustments to historical loss information are made for differences in relevant current loan-specific risk characteristics, such as historical timing of losses relative to the loan origination. In its loss forecasting framework, the Company incorporates forward-looking information through the use of macroeconomic scenarios applied over the forecasted life of the assets. These macroeconomic scenarios incorporate variables that have historically been key drivers of increases and decreases in credit losses. These variables include, but are not limited to changes in environmental conditions, such as California unemployment rates, household debt levels and U.S. gross domestic product. A loan is considered to be collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral. The ACL on collateral dependent loans is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. If the value of underlying collateral is determined to be less than the recorded amount of the loan, a charge-off will be taken. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a TDR. The ACL on a TDR is measured using the same method as all other portfolio loans, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the ACL is determined by discounting the expected future cash flows at the original interest rate of the loan. PCD assets are assets acquired at a discount that is due, in part, to credit quality deterioration since origination. PCD assets are accounted for in accordance with ASC 326-20 and are initially recorded at fair value, by taking the sum of the present value of expected future cash flows and an allowance for credit losses, at acquisition. The allowance for credit losses for PCD assets is recorded through a gross-up of reserves on the balance sheet, while the allowance for acquired non-PCD assets, such as loans, is recorded through the provision for credit losses on the income statement, consistent with originated loans. Subsequent to acquisition, the allowance for credit losses for PCD loans will generally follow the same forward-looking estimation, provision, and charge-off process as non-PCD acquired and originated loans. The Company has identified the following portfolio segments to evaluate and measure the allowance for credit loss: Commercial real estate : Commercial real estate - Non-owner occupied: These commercial properties typically consist of buildings which are leased to others for their use and rely on rents as the primary source of repayment. Property types are predominantly office, retail, or light industrial but the portfolio also has some special use properties. As such, the risk of loss associated with these properties is primarily driven by general economic changes or changes in regional economies and the impact of such on a tenant’s ability to pay. Ultimately this can affect occupancy, rental rates, or both. Additional risk of loss can come from new construction resulting in oversupply, the costs to hold or operate the property, or changes in interest rates. The terms on these loans at origination typically have maturities from five fifteen Commercial real estate - Owner occupied: These credits are primarily susceptible to changes in the financial condition of the business operated by the property owner. This may be driven by changes in, among other things, industry challenges, factors unique to the operating geography of the borrower, change in the individual fortunes of the business owner, general economic conditions and changes in business cycles. When default is driven by issues related specifically to the business owner, collateral values tend to provide better repayment support and may result in little or no loss. Alternatively, when default is driven more by general economic conditions, the underlying collateral may have devalued more and thus result in larger losses in the event of default. The terms on these loans at origination typically have maturities from five fifteen Multifamily: These commercial properties are generally comprised of more than four rentable units, such as apartment buildings, with each unit intended to be occupied as the primary residence for one or more persons. Multifamily properties are also subject to changes in general or regional economic conditions, such as unemployment, ultimately resulting in increased vacancy rates or reduced rents or both. In addition, new construction can create an oversupply condition and market competition resulting in increased vacancy, reduced market rents, or both. Due to the nature of their use and the greater likelihood of tenant turnover, the management of these properties is more intensive and therefore is more critical to the preclusion of loss. Farmland: While the Company has few loans that were originated for the purpose of the acquisition of these commercial properties, loans secured by farmland represent unique risks that are associated with the operation of an agricultural businesses. The valuation of farmland can vary greatly over time based on the property's access to resources including but not limited to water, crop prices, foreign exchange rates, government regulation or restrictions, and the nature of ongoing capital investment needed to maintain the quality of the property. Loans secured by farmland typically represent less risk to the Company than other agriculture loans as the real estate typically provides greater support in the event of default or need for longer term repayment. Consumer loans : SFR 1-4 1st DT Liens: The most significant drivers of potential loss within the Company's residential real estate portfolio relate general, regional, or individual changes in economic conditions and their effect on employment and borrowers cash flow. Risk in this portfolio is best measured by changes in borrower credit score and loan-to-value. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the value of homes and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate. SFR HELOCs and Junior Liens: Similar to residential real estate term loans, HELOCs and junior liens performance is also primarily driven by borrower cash flows based on employment status. However, HELOCs carry additional risks associated with the fact that most of these loans are secured by a deed of trust in a position that is junior to the primary lien holder. Furthermore, the risk that as the borrower's financial strength deteriorates, the outstanding balance on these credit lines may increase as they may only be canceled by the Company if certain limited criteria are met. In addition to the allowance for credit losses maintained as a percent of the outstanding loan balance, the Company maintains additional reserves for the unfunded portion of the HELOC. Other: The majority of consumer loans are secured by automobiles, with the remainder primarily unsecured revolving debt (credit cards). These loans are susceptible to three primary risks; non-payment due to income loss, over-extension of credit and, when the borrower is unable to pay, shortfall in collateral value, if any. Typically non-payment is due to loss of job and will follow general economic trends in the marketplace driven primarily by rises in the unemployment rate. Loss of collateral value can be due to market demand shifts, damage to collateral itself or a combination of those factors. Credit card loans are unsecured and while collection efforts are pursued in the event of default, there is typically limited opportunity for recovery. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate. Commercial and Industrial: Repayment of these loans is primarily based on the cash flow of the borrower, and secondarily on the underlying collateral provided by the borrower. A borrower's cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Most often, collateral includes accounts receivable, inventory, or equipment. Collateral securing these loans may depreciate over time, may be difficult to appraise, may be illiquid and may fluctuate in value based on the success of the business. Actual and forecast changes in gross domestic product are believed to be corollary to losses associated with these credits. Construction : While secured by real estate, construction loans represent a greater level of risk than term real estate loans due to the nature of the additional risks associated with the not only the completion of construction within an estimated time period and budget, but also the need to either sell the building or reach a level of stabilized occupancy sufficient to generate the cash flows necessary to support debt service and operating costs. The Company seeks to mitigate the additional risks associated with construction lending by requiring borrowers to comply with lower loan to value ratios and additional covenants as well as strong tertiary support of guarantors. The loss forecasting model applies the historical rate of loss for similar loans over the expected life of the asset as adjusted for macroeconomic factors. Agriculture Production: Repayment of agricultural loans is dependent upon successful operation of the agricultural business, which is greatly impacted by factors outside the control of the borrower. These factors include adverse weather conditions, including access to water, that may impact crop yields, loss of livestock due to disease or other factors, declines in market prices for agriculture products, changes in foreign exchange, and the impact of government regulations. In addition, many farms are dependent on a limited number of key individuals whose injury or death may significantly affect the successful operation of the business. Consequently, agricultural production loans may involve a greater degree of risk than other types of loans. Leases: The loss forecasting model applies the historical rate of loss for similar loans over the expected life of the asset. Leases typically represent an elevated level of credit risk as compared to loans secured by real estate as the collateral for leases is often subject to a more rapid rate of depreciation or depletion. The ultimate severity of loss is impacted by the type of collateral securing the exposure, the size of the exposure, the borrower’s industry sector, any guarantors and the geographic market. Assumptions of expected loss are conditioned to the economic outlook and the other variables discussed above. Unfunded commitments : The estimated credit losses associated with these unfunded lending commitments is calculated using the same models and methodologies noted above and incorporate utilization assumptions at time of default. The reserve for unfunded commitments is maintained on the consolidated balance sheet in other liabilities. Accounting Standards Pending Adoption FASB issued ASU 2022-02, Financial Instruments — Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This ASU addresses feedback received from adopters of CECL, specifically regarding accounting guidance for TDRs and disclosures of gross write-offs by year of loan origination. Accounting guidance for TDRs by creditors will be eliminated under this amendment, while also enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. Amendments in this ASU are effective for the Company beginning after December 31, 2022, with early adoption permitted. Management is evaluating the extent to which this will impact the consolidated financial statements. FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform by providing optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected if certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The election to apply the optional relief for existing fair value and cash flow hedge accounting relationships may be made on a hedge-by-hedge basis and across multiple reporting periods. Amendments in this ASU are effective for the Company through December 31, 2022. As the Company has an insignificant number of instruments that are applicable to this ASU, management has determined that no impact to the valuations of these instruments are applicable for financial reporting purposes.

Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business Combinations On March 25, 2022, the Company completed its acquisition of Valley Republic Bancorp, including the merger of Valley Republic Bank into Tri Counties Bank, with Tri Counties Bank as the surviving entity, in accordance with the terms of the merger agreement dated as of July 27, 2021. The cash and stock transaction was valued at approximately $174.0 million in aggregate, based on TriCo's closing stock price of $42.48 on March 25, 2022. Under the terms of the merger agreement, the Company issued approximately 4.1 million shares, in addition to approximately $431,000 in cash paid out for settlement of stock option awards at VRB. VRB was headquartered in Bakersfield, California, and had four branch locations in and around Bakersfield, which all now operate as branches for Tri Counties Bank, and a loan production office in Fresno, California. The Company anticipates that Tri Counties Bank's previously existing Bakersfield branch and the VRB loan production office in Fresno will be consolidated, subject to regulatory approval, into the overlapping locations in the near future. The acquisition of VRB has been accounted for as a business combination. We recorded the fair values based on the valuations available as of reporting date. In accordance with business combination accounting guidance, we will continue to evaluate these fair values for up to one year following the merger date of March 25, 2022. While management believes the information available and presented below provide a reasonable basis for estimating fair value, we may obtain additional information and evidence during the measurement period that could result in changes to the estimated fair value amounts. Valuations subject to change include, but are not limited to, loans and leases, deposits, deferred tax items, and certain other assets and liabilities. The following table summarizes the consideration paid for VRB and the amounts of assets acquired and liabilities assumed that were recorded at the acquisition date (in thousands): Valley Republic Bancorp Fair value of consideration transferred: Fair value of shares issued $ 173,585 Cash consideration 431 Total fair value of consideration transferred 174,016 Assets acquired: Cash and cash equivalents 427,314 Securities available for sale 109,716 Loans and leases 771,353 Premises and equipment 4,658 Cash value of life insurance 13,609 Core deposit intangible 10,635 Other assets 26,244 Total assets acquired 1,363,529 Liabilities assumed: Deposits (1,215,479) Subordinated debt (47,236) SERP liability (3,352) Other liabilities (10,516) Total liabilities assumed (1,276,583) Total net assets acquired 86,946 Goodwill recognized $ 87,070

Investment securities with an aggregate carrying value of $475,674,000 and $423,892,000 at March 31, 2022 and December 31, 2021, respectively, were pledged as collateral for specific borrowings, lines of credit or local agency deposits. The amortized cost and estimated fair value of debt securities at March 31, 2022 by contractual maturity are shown below. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. At March 31, 2022, obligations of U.S. government corporations and agencies with a cost basis totaling $1,404,095,000 consist almost entirely of residential real estate mortgage-backed securities whose contractual maturity, or principal repayment, will follow the repayment of the underlying mortgages. For purposes of the following table, the entire outstanding balance of these mortgage-backed securities issued by U.S. government corporations and agencies is categorized based on final maturity date. At March 31, 2022, the Company estimates the average remaining life of these mortgage-backed securities issued by U.S. government corporations and agencies to be approximately 6.28 years. Average remaining life is defined as the time span after which the principal balance has been reduced by half. As of March 31, 2022, the contractual final maturity for available for sale and held to maturity investment securities is as follows: Debt Securities Available for Sale Held to Maturity (in thousands) Amortized Estimated Amortized Estimated Due in one year $ 14,060 $ 13,955 $ — $ — Due after one year through five years 124,473 120,609 1,693 1,717 Due after five years through ten years 376,294 370,606 14,559 14,431 Due after ten years 1,959,774 1,857,737 170,496 167,822 Totals $ 2,474,601 $ 2,362,907 $ 186,748 $ 183,970 Gross unrealized losses on debt securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, were as follows: March 31, 2022: Less than 12 months 12 months or more Total (in thousands) Fair Unrealized Fair Unrealized Fair Unrealized Debt Securities Available for Sale Obligations of U.S. government agencies $ 1,385,647 $ (79,940) $ 220,899 $ (19,112) $ 1,606,546 $ (99,052) Obligations of states and political subdivisions 106,944 (10,040) 9,045 (1,364) 115,989 (11,404) Corporate bonds 4,112 (65) — — 4,112 (65) Asset backed securities 212,168 (2,544) 107,603 (2,301) 319,771 (4,845) Total debt securities available for sale $ 1,708,871 $ (92,589) $ 337,547 $ (22,777) $ 2,046,418 $ (115,366) Debt Securities Held to Maturity Obligations of U.S. government agencies $ 147,078 $ (3,070) $ — $ — $ 147,078 $ (3,070) December 31, 2021: Less than 12 months 12 months or more Total (in thousands) Fair Unrealized Fair Unrealized Fair Unrealized Debt Securities Available for Sale Obligations of U.S. government agencies $ 947,108 $ (9,737) $ 44,086 $ (1,293) $ 991,194 $ (11,030) Obligations of states and political subdivisions 56,153 (785) — — 56,153 (785) Asset backed securities 389,837 (4,118) 109,748 (872) 499,585 (4,990) Total debt securities available for sale $ 1,393,098 $ (14,640) $ 153,834 $ (2,165) $ 1,546,932 $ (16,805) Obligations of U.S. government agencies: The unrealized losses on investments in obligations of U.S. government agencies are caused by interest rate increases and illiquidity. The contractual cash flows of these securities are guaranteed by U.S. Government Sponsored Entities (principally Fannie Mae and Freddie Mac). It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because management believes the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell and more likely than not will not be required to sell, there is no impairment on these securities and there has been no allowance for credit losses recorded. At March 31, 2022, 199 debt securities representing obligations of U.S. government agencies had unrealized losses with aggregate depreciation of 5.50% from the Company’s amortized cost basis. Obligations of states and political subdivisions: The unrealized losses on investments in obligations of states and political subdivisions were caused by increases in required yields by investors in these types of securities. It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because management believes the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell and more likely than not will not be required to sell, there is no impairment on these securities and there has been no allowance for credit losses recorded as of March 31, 2022. At March 31, 2022, 79 debt securities representing obligations of states and political subdivisions had unrealized losses with aggregate depreciation of 8.95% from the Company’s amortized cost basis. Corporate bonds: The unrealized losses on investments in corporate bonds were caused by increases in required yields by investors in these types of securities. It is expected that the securities would not be settled at a price less than the amortized cost of the investment. Because management believes the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell and more likely than not will not be required to sell, there is no impairment on these securities and there has been no allowance for credit losses recorded as of March 31, 2022. At March 31, 2022, 3 debt securities representing corporate bonds had unrealized losses with aggregate depreciation of 1.56% from the Company’s amortized cost basis. Asset backed securities: The unrealized losses on investments in asset backed securities were caused by increases in required yields by investors for these types of securities. At the time of purchase, each of these securities was rated AA or AAA and through March 31, 2022 has not experienced any deterioration in credit rating. At March 31, 2022, 29 asset backed securities had unrealized losses with aggregate depreciation of 1.49% from the Company’s amortized cost basis. The Company continues to monitor these securities for changes in credit rating or other indications of credit deterioration. Because management believes the decline in fair value is attributable to changes in interest rates and not credit quality, and because the Company does not intend to sell and more likely than not will not be required to sell, there is no impairment on these securities and there has been no allowance for credit losses recorded as of March 31, 2022. The Company monitors credit quality of debt securities held-to-maturity through the use of credit rating. The Company monitors the credit rating on a monthly basis.

Tri Counties Bank, through its online portal, facilitated the ability for borrowers to open a new deposit account and submit PPP applications during the entirety of the Programs. The SBA ended PPP and did not accept new borrowing applications, effective May 31, 2021. PPP loan balances included in commercial and industrial loan totals above were $56,605,000 and $61,147,000, net of approximately $1,190,000 and $2,164,000 in deferred fee income as of March 31, 2022 and December 31, 2021, respectively. During the three months ended March 31, 2022, the Company recognized $974,000 in fees on PPP loans as compared with $3,482,000 and $4,978,000 for the three months ended December 31, 2021 and March 31, 2021, respectively. Based on the payment guarantee provided by the SBA as well as the expected short-term duration of the PPP loans acquired from VRB, the fair value of these loans approximates the principal balance outstanding as of the merger date, and therefore, no purchase discount was recorded.

To estimate expected losses the Company generally utilizes historical loss trends and the remaining contractual lives of the loan portfolios to determine estimated credit losses through a reasonable and supportable forecast period. Individual loan credit quality indicators including loan grade and borrower repayment performance have been statistically correlated with historical credit losses and various econometrics, including California unemployment, gross domestic product, and corporate bond yields. Model forecasts may be adjusted for inherent limitations or biases that have been identified through independent validation and back-testing of model performance to actual realized results. The Company utilizes a forecast period of approximately eight quarters and obtains the forecast data from publicly available sources as of the balance sheet date. This forecast data continues to evolve and included improving shifts in the magnitude of changes for both the unemployment and GDP factors leading up to the balance sheet date. However, management notes that the majority of economic forecasts utilized in the ACL calculation have remained directionally consistent with preceding quarters, as general economic conditions continue to improve, albeit at a pace slower than expected due to unforeseen disruptions in the supply chain and increasing energy prices. In addition, management notes that the level of governmental assistance provided through PPP as well as other programs during the last several quarters has been unprecedented. As a result, management continues to believe that certain credit weakness are likely present in the overall economy and that it is appropriate to maintain a reserve level that incorporates such risk factors. Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. The following table provides a summary of loans and leases purchased as part of the VRB acquisition with credit deterioration at acquisition: As of March 25, 2022 (in thousands) Commercial Real Estate Consumer Commercial and Industrial Construction Agriculture Production Total Par value $ 27,237 $ 3,877 $ 2,674 $ 25,645 $ 9,080 $ 68,513 ACL at acquisition (1,573) (144) (81) (201) (38) (2,037) Non-credit discount (2,305) (360) (47) (232) (12) (2,956) Purchase price $ 23,359 $ 3,373 $ 2,546 $ 25,212 $ 9,030 $ 63,520 For the periods indicated, the following tables summarize the activity in the allowance for credit losses on loans which is recorded as a contra asset, and the reserve for unfunded commitments which is recorded on the balance sheet within other liabilities: Allowance for credit losses – Year ended December 31, 2021 (in thousands) Beginning Charge-offs Recoveries Provision Ending Balance Commercial real estate: CRE non-owner occupied $ 29,380 $ — $ 12 $ (3,653) $ 25,739 CRE owner occupied 10,861 (18) 794 (946) 10,691 Multifamily 11,472 — — 923 12,395 Farmland 1,980 (126) — 461 2,315 Total commercial real estate loans 53,693 (144) 806 (3,215) 51,140 Consumer: SFR 1-4 1st DT liens 10,117 (145) 13 738 10,723 SFR HELOCs and junior liens 11,771 (29) 1,127 (2,359) 10,510 Other 3,260 (577) 361 (803) 2,241 Total consumer loans 25,148 (751) 1,501 (2,424) 23,474 Commercial and industrial 4,252 (1,470) 755 325 3,862 Construction 7,540 (27) — (1,846) 5,667 Agriculture production 1,209 — 24 (18) 1,215 Leases 5 — — 13 18 Allowance for credit losses on loans $ 91,847 $ (2,392) $ 3,086 $ (7,165) $ 85,376 Reserve for unfunded commitments 3,400 — — 390 3,790 Total $ 95,247 $ (2,392) $ 3,086 $ (6,775) $ 89,166 Allowance for credit losses – Three months ended March 31, 2021 (in thousands) Beginning Charge-offs Recoveries Provision Ending Balance Commercial real estate: CRE non-owner occupied $ 29,380 $ — $ 2 $ (2,948) $ 26,434 CRE owner occupied 10,861 — 1 (988) 9,874 Multifamily 11,472 — — 899 12,371 Farmland 1,980 — — (256) 1,724 Total commercial real estate loans 53,693 — 3 (3,293) 50,403 Consumer: SFR 1-4 1st DT liens 10,117 — 10 538 10,665 SFR HELOCs and junior liens 11,771 — 285 (977) 11,079 Other 3,260 (193) 106 (313) 2,860 Total consumer loans 25,148 (193) 401 (752) 24,604 Commercial and industrial 4,252 (33) 136 109 4,464 Construction 7,540 — — (2,064) 5,476 Agriculture production 1,209 — 20 (241) 988 Leases 5 — — 1 6 Allowance for credit losses on loans $ 91,847 $ (226) $ 560 $ (6,240) $ 85,941 Reserve for unfunded commitments 3,400 — — 180 3,580 Total $ 95,247 $ (226) $ 560 $ (6,060) $ 89,521 As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including, but not limited to, trends relating to (i) the level of criticized and classified loans, (ii) net charge-offs, (iii) non-performing loans, and (iv) delinquency within the portfolio. The Company analyzes loans individually to classify the loans as to credit risk and grading. This analysis is performed annually for all outstanding balances greater than $1,000,000 and non-homogeneous loans, such as commercial real estate loans, unless other indicators, such as delinquency, trigger more frequent evaluation. Loans below the $1,000,000 threshold and homogenous in nature are evaluated as needed for proper grading based on delinquency and borrower credit scores. The Company utilizes a risk grading system to assign a risk grade to each of its loans. Loans are graded on a scale ranging from Pass to Loss. A description of the general characteristics of the risk grades is as follows: • Pass – This grade represents loans ranging from acceptable to very little or no credit risk. These loans typically meet most if not all policy standards in regard to: loan amount as a percentage of collateral value, debt service coverage, profitability, leverage, and working capital. • Special Mention – This grade represents “Other Assets Especially Mentioned” in accordance with regulatory guidelines and includes loans that display some potential weaknesses which, if left unaddressed, may result in deterioration of the repayment prospects for the asset or may inadequately protect the Company’s position in the future. These loans warrant more than normal supervision and attention. • Substandard – This grade represents “Substandard” loans in accordance with regulatory guidelines. Loans within this rating typically exhibit weaknesses that are well defined to the point that repayment is jeopardized. Loss potential is, however, not necessarily evident. The underlying collateral supporting the credit appears to have sufficient value to protect the Company from loss of principal and accrued interest, or the loan has been written down to the point where this is true. There is a definite need for a well-defined workout/rehabilitation program. • Doubtful – This grade represents “Doubtful” loans in accordance with regulatory guidelines. An asset classified as Doubtful has all the weaknesses inherent in a loan classified Substandard 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. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral, and financing plans. • Loss – This grade represents “Loss” loans in accordance with regulatory guidelines. A loan classified as Loss is considered uncollectible and of such little value that its continuance as a bankable asset is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the loan, even though some recovery may be affected in the future. The portion of the loan that is graded loss should be charged off no later than the end of the quarter in which the loss is identified.

If the borrower was experiencing financial difficulty and a concession was granted, the Company considered such modifications as troubled debt restructurings. Modifications classified as TDRs can include one or a combination of the following: rate modifications, term extensions, interest only modifications, either temporary or long-term, payment modifications, and collateral substitutions/additions. The objective of the modifications was to increase loan repayments by customers and thereby reduce net charge-offs. The modified loans are included in impaired loans for purposes of determining the level of the allowance for credit losses. For all new TDRs, an impairment analysis is conducted. If the loan is determined to be collateral dependent, any additional amount of impairment will be calculated based on the difference between estimated collectible value and the current carrying balance of the loan. This difference could result in an increased provision and is typically charged off. If the asset is determined not to be collateral dependent, the impairment is measured on the net present value difference between the expected cash flows of the restructured loan and the cash flows which would have been received under the original terms. The effect of this could result in a requirement for additional provision to the reserve. The effect of these required provisions for the period are indicated above.

Leases [Abstract]
Leases	Leases The Company records a ROUA on the consolidated balance sheets for those leases that convey rights to control use of identified assets for a period of time in exchange for consideration. The Company also records a lease liability on the consolidated balance sheets for the present value of future payment commitments. All of the Company’s leases are comprised of operating leases in which the Company is lessee of real estate property for branches, ATM locations, and general administration and operations. The Company has elected not to include short-term leases (i.e. leases with initial terms of 12 month or less) within the ROUA and lease liability. Known or determinable adjustments to the required minimum future lease payments were included in the calculation of the Company’s ROUA and lease liability. Adjustments to the required minimum future lease payments that are variable and will not be determinable until a future period, such as changes in the consumer price index, are included as variable lease costs. Additionally, expected variable payments for common area maintenance, taxes and insurance were unknown and not determinable at lease commencement and therefore, were not included in the determination of the Company’s ROUA or lease liability. The value of the ROUA and lease liability is impacted by the amount of the periodic payment required, length of the lease term, and the discount rate used to calculate the present value of the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. The lease liability is reduced based on the discounted present value of remaining payments as of each reporting period. The ROUA value is measured using the amount of lease liability and adjusted for prepaid or accrued lease payments, remaining lease incentives, unamortized direct costs (if any), and impairment (if any). The following table presents the components of lease expense for the periods ended: Three months ended March 31, (in thousands) 2022 2021 Operating lease cost $ 1,319 $ 1,258 Short-term lease cost 53 61 Variable lease cost 2 (2) Sublease income — (13) Total lease cost $ 1,374 $ 1,304 The following table presents supplemental cash flow information related to leases for the periods ended: Three months ended March 31, (in thousands) 2022 2021 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows for operating leases $ 1,292 $ 1,204 ROUA obtained in exchange for operating lease liabilities $ 3,867 $ 1,308 The following table presents the weighted average operating lease term and discount rate as of the period ended: March 31, 2022 2021 Weighted-average remaining lease term (years) 8.8 9.8 Weighted-average discount rate 2.90 % 3.03 % At March 31, 2022, future expected operating lease payments are as follows: (in thousands) Periods ending December 31, 2022 $ 4,321 2023 5,146 2024 4,694 2025 4,017 2026 3,612 Thereafter 13,378 35,168 Discount for present value of expected cash flows (4,668) Lease liability at March 31, 2022 $ 30,500

Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity Dividends Paid The Bank paid to the Company cash dividends in the aggregate amounts of $7,782,000 and $7,772,000 during the three months ended March 31, 2022 and 2021, respectively. The Bank is regulated by the FDIC and the DFPI. Absent approval from the Commissioner of the DFPI, California banking laws generally limit the Bank’s ability to pay dividends to the lesser of (1) retained earnings or (2) net income for the last three fiscal years, less cash distributions paid during such period. Stock Repurchase Plan On February 25, 2021 the Board of Directors authorized the repurchase of up to 2,000,000 shares of the Company's common stock (the 2021 Repurchase Plan), which approximated 6.7% of the shares outstanding as of the approval date. The actual timing of any share repurchases will be determined by the Company's management and therefore the total value of the shares to be purchased under the 2021 Repurchase Plan is subject to change. The 2021 Repurchase Plan has no expiration date (in accordance with applicable laws and regulations) and no share repurchases were made by the Company during either of the three month periods ending March 31, 2022 and March 31, 2021. In connection with approval of the 2021 Repurchase Plan, the Company’s previous repurchase program adopted on November 12, 2019 (the 2019 Repurchase Plan) was terminated. Under the 2019 Repurchase Plan, the Company repurchased 223 shares during the three months ended March 31, 2021. Stock Repurchased Under Equity Compensation Plans The Company's shareholder-approved equity compensation plans permit employees to tender recently vested shares in lieu of cash for the payment of exercise price, if applicable, and the tax withholding on such shares. During the three months ended March 31, 2022 and 2021, employees tendered zero shares, respectively, of the Company’s common stock in connection with option exercises. Employees also tendered zero and 70 shares in connection with the tax withholding requirements of other share based awards during the three months ended March 31, 2022 and 2021, respectively. In total, shares of the Company's common stock tendered had market values of $55,145 and $2,500 during the quarters ended March 31, 2022 and 2021, respectively. The tendered shares were retired. The market value of tendered shares is the last market trade price at closing on the day an option is exercised or the other share based award vests. Stock repurchased under equity incentive plans are not included in the total of stock repurchased under the 2021 or 2019 Stock Repurchase Plans.

Stock Options and Other Equity-Based Incentive Instruments	Stock Options and Other Equity-Based Incentive Instruments On April 16, 2019, the Board of Directors adopted the 2019 Equity Incentive Plan (2019 Plan) which was approved by shareholders on May 21, 2019. The 2019 Plan allows for up to 1,500,000 shares to be issued in connection with equity-based incentives. The Company’s 2009 Equity Incentive Plan (2009 Plan) expired on March 26, 2019. While no new awards can be granted under the 2009 Plan, existing grants continue to be governed by the terms, conditions and procedures set forth in any applicable award agreement. Stock option activity during the three months ended March 31, 2022 is summarized in the following table: Number Weighted Outstanding at December 31, 2021 78,825 $ 19.28 Options granted — — Options exercised (3,325) 16.59 Options forfeited — — Outstanding at March 31, 2022 75,500 $ 19.40 The following table shows the number, weighted-average exercise price, intrinsic value, and weighted average remaining contractual life of options exercisable, options not yet exercisable and total options outstanding as of March 31, 2022: Currently Currently Not Total Number of options 75,500 — 75,500 Weighted average exercise price $ 19.40 $ — $ 19.40 Intrinsic value (in thousands) $ 1,558 $ — $ 1,558 Weighted average remaining contractual term (yrs.) 1.1 0 years 1.1 As of March 31, 2022 all options outstanding are fully vested and are expected to be exercised prior to expiration. The Company did not modify any option grants during 2021 or the three months ended March 31, 2022. Activity related to restricted stock unit awards during the three months ended March 31, 2022 is summarized in the following table: Service Market Plus Outstanding at December 31, 2021 103,517 99,763 RSUs granted 21,597 — RSUs added through dividend and performance credits — — RSUs released 730 — RSUs forfeited/expired — — Outstanding at March 31, 2022 125,844 99,763 The 125,844 of service condition vesting RSUs outstanding as of March 31, 2022 include a feature whereby each RSU outstanding is credited with a dividend amount equal to any common stock cash dividend declared and paid, and the credited amount is divided by the closing price of the Company’s stock on the dividend payable date to arrive at an additional amount of RSUs outstanding under the original grant. The dividend credits follow the same vesting requirements as the RSU awards and are not considered participating securities. The 125,844 of service condition vesting RSUs outstanding as of March 31, 2022 are expected to vest, and be released, on a weighted-average basis, over the next 2.0 years. The Company expects to recognize $3,269,785 of pre-tax compensation costs related to these service condition vesting RSUs between March 31, 2022 and their vesting dates. The Company did not modify any service condition vesting RSUs during 2021 or during the three months ended March 31, 2022. The 99,763 of market plus service condition vesting RSUs outstanding as of March 31, 2022 are expected to vest, and be released, on a weighted-average basis, over the next 1.8 years. The Company expects to recognize $1,352,856 of pre-tax compensation costs related to these RSUs between March 31, 2022 and their vesting dates. As of March 31, 2022, the number of market plus service condition vesting RSUs outstanding that will actually vest, and be released, may be reduced to zero or increased to 149,645 depending on the total return of the Company’s common stock versus the total return of an index of bank stocks from the grant date to the vesting date. The Company did not modify any market plus service condition vesting RSUs during 2021 or during the three months ended March 31, 2022.

Earnings Per Share	Earnings Per Share Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options and restricted stock units (RSUs), and are determined using the treasury stock method. Earnings per share have been computed based on the following: Three months ended March 31, (in thousands) 2022 2021 Net income $ 20,374 $ 33,649 Average number of common shares outstanding 30,050 29,727 Effect of dilutive stock options and restricted stock 152 178 Average number of common shares outstanding used to calculate diluted earnings per share 30,202 29,905 Options excluded from diluted earnings per share because of their antidilutive effect — —

Comprehensive Income (Loss)	Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available-for-sale securities, are reported as a separate component of the equity section of the balance sheet identified as accumulated other comprehensive income (AOCI), such items, along with net income, are components of other comprehensive income (loss) (OCI).

Fair Value Measurement

Fair Value Measurement	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, income approach, and/or the cost approach. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset and the risk of nonperformance. Marketable equity securities, debt securities available-for-sale, loans held for sale, and mortgage servicing rights are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such loans held for investment and certain other assets. These nonrecurring fair value adjustments typically involve application impairment write-downs of individual assets. The Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observable nature of the assumptions used to determine fair value. These levels are: Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets. Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 3 - Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. Marketable equity securities and debt securities available for sale - Marketable equity securities and debt securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. The Company had no securities classified as Level 3 during any of the periods covered in these financial statements. Loans held for sale - Loans held for sale are carried at the lower of cost or fair value. The fair value of loans held for sale is based on what secondary markets are currently offering for loans with similar characteristics. As such, we classify those loans subjected to recurring fair value adjustments as Level 2. Individually evaluated loans - Loans are not recorded at fair value on a recurring basis. However, from time to time, certain loans have individual risk characteristics not consistent with a pool of loans and is individually evaluated for credit reserves. Loans for which it is probable that payment of interest and principal will not be made in accordance with the original contractual terms of the loan agreement are typically individually evaluated. The fair value of these loans are estimated using one of several methods, including collateral value, fair value of similar debt, enterprise value, liquidation value and discounted cash flows. Those loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans. Loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When the fair value of the collateral is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the loan as nonrecurring Level 3. Foreclosed assets - Foreclosed assets include assets acquired through, or in lieu of, loan foreclosure. Foreclosed assets are held for sale and are initially recorded at fair value at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value less cost to sell. When the fair value of foreclosed assets is based on an observable market price or a current appraised value which uses substantially observable data, the Company records the loan as nonrecurring Level 2. When an appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value, or the appraised value contains a significant unobservable assumption, such as deviations from comparable sales, and there is no observable market price, the Company records the foreclosed asset as nonrecurring Level 3. Revenue and expenses from operations and changes in the valuation allowance are included in other non-interest expense. Mortgage servicing rights - Mortgage servicing rights are carried at fair value. A valuation model, which utilizes a discounted cash flow analysis using a discount rate and prepayment speed assumptions is used in the computation of the fair value measurement. While the prepayment speed assumption is currently quoted for comparable instruments, the discount rate assumption currently requires a significant degree of management judgment and is therefore considered an unobservable input. As such, the Company classifies mortgage servicing rights subjected to recurring fair value adjustments as Level 3. The table below presents the recorded amount of assets and liabilities measured at fair value on a recurring basis (in thousands): Fair value at March 31, 2022 Total Level 1 Level 2 Level 3 Marketable equity securities $ 2,801 $ 2,801 Debt securities available for sale: Obligations of U.S. government corporations and agencies 1,690,744 1,690,744 Obligations of states and political subdivisions 267,195 267,195 Corporate bonds 7,616 7,616 Asset backed securities 397,352 397,352 Loans held for sale 1,030 1,030 Mortgage servicing rights 6,405 6,405 Total assets measured at fair value $ 2,373,143 $ 2,801 $ 2,363,937 $ 6,405 Fair value at December 31, 2021 Total Level 1 Level 2 Level 3 Marketable equity securities $ 2,938 $ 2,938 $ — $ — Debt securities available for sale: Obligations of U.S. government corporations and agencies 1,257,389 — 1,257,389 — Obligations of states and political subdivisions 192,244 — 192,244 — Corporate bonds 6,756 — 6,756 — Asset backed securities 751,549 — 751,549 — Loans held for sale 3,466 — 3,466 — Mortgage servicing rights 5,874 — — 5,874 Total assets measured at fair value $ 2,220,216 $ 2,938 $ 2,211,404 $ 5,874 Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally corresponds with the Company’s quarterly valuation process. There were no transfers between any levels during the three months ended March 31, 2022, or the year ended December 31, 2021. The following table provides a reconciliation of assets and liabilities measured at fair value using significant unobservable inputs (Level 3) on a recurring basis during the time periods indicated. Had there been any transfer into or out of Level 3 during the time periods indicated, the amount included in the “Transfers into (out of) Level 3” column would represent the beginning balance of an item in the period (interim quarter) during which it was transferred (in thousands): Three months ended March 31, Beginning Transfers Change Issuances Ending 2022: Mortgage servicing rights $ 5,874 — $ 274 $ 257 $ 6,405 2021: Mortgage servicing rights $ 5,092 — $ 12 $ 503 $ 5,607 Three months ended March 31, The key unobservable inputs used in determining the fair value of mortgage servicing rights are mortgage prepayment speeds and the discount rate used to discount cash projected cash flows. Generally, any significant increases in the mortgage prepayment speed and discount rate utilized in the fair value measurement of the mortgage servicing rights will result in a negative fair value adjustments (and decrease in the fair value measurement). Conversely, a decrease in the mortgage prepayment speed and discount rate will result in a positive fair value adjustment (and increase in the fair value measurement). The following table presents quantitative information about recurring Level 3 fair value measurements at March 31, 2022 and December 31, 2021: As of March 31, 2022: Fair Value Valuation Unobservable Range, Mortgage Servicing Rights $ 6,405 Discounted cash flow Constant prepayment rate 9% - 16%; 9.8% Discount rate 10% - 14%; 12% As of December 31, 2021: Mortgage Servicing Rights $ 5,874 Discounted cash flow Constant prepayment rate 11% - 15.8%; 12.5% Discount rate 10% - 14%; 12% The tables below present the recorded investment in assets and liabilities measured at fair value on a nonrecurring basis, as of the dates indicated (in thousands): March 31, 2022 Total Level 1 Level 2 Level 3 Total Losses Fair value: Individually evaluated loans $ 684 — — $ 684 $ (615) Foreclosed assets 313 — — 313 (294) Total assets measured at fair value $ 997 $ — $ — $ 997 $ (909) December 31, 2021 Total Level 1 Level 2 Level 3 Total Losses Fair value: Individually evaluated loans $ 3,683 — — $ 3,683 $ (1,105) Foreclosed assets — — — — — Total assets measured at fair value $ 3,683 — — $ 3,683 $ (1,105) March 31, 2021 Total Level 1 Level 2 Level 3 Total Losses Fair value: Individually evaluated loans $ 4,557 — — $ 4,557 $ (2,710) Foreclosed assets 214 — — 214 (31) Total assets measured at fair value $ 4,771 — — $ 4,771 $ (2,741) The individually evaluated loan amounts above represent collateral dependent loans that have been adjusted to fair value. When the Company identifies a collateral dependent loan with unique risk characteristics, the Company evaluates the need for an allowance using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan, the fair value of collateral is generally estimated by obtaining external appraisals. If the Company determines that the value of the loan is less than the recorded investment in the loan, the Company recognizes this impairment and adjust the carrying value of the loan to fair value through the allowance for credit losses. The loss represents charge-offs or impairments on collateral dependent loans for fair value adjustments based on the fair value of collateral. The carrying value of loans fully charged-off is zero. The foreclosed assets amount above represents impaired real estate that has been adjusted to fair value. Foreclosed assets represent real estate which the Company has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at fair value less costs to sell, which becomes the property’s new basis. Any write-downs based on the asset’s fair value at the date of acquisition are charged to the allowance for credit losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within net loss on real estate owned. The loss represents impairments on real estate owned for fair value adjustments based on the fair value of the real estate. The Company’s property appraisals are primarily based on the sales comparison approach and income approach methodologies, which consider recent sales of comparable properties, including their income generating characteristics, and then make adjustments to reflect the general assumptions that a market participant would make when analyzing the property for purchase. These adjustments may increase or decrease an appraised value and can vary significantly depending on the location, physical characteristics and income producing potential of each property. Additionally, the quality and volume of market information available at the time of the appraisal can vary from period to period and cause significant changes to the nature and magnitude of comparable sale adjustments. Given these variations, comparable sale adjustments are generally not a reliable indicator for how fair value will increase or decrease from period to period. Under certain circumstances, management discounts are applied based on specific characteristics of an individual property.

The Company uses the exit price notion when measuring the fair value of financial instruments. These estimates are subjective and may vary significantly from amounts that would be realized in actual transactions. In addition, other significant assets are not considered financial assets including, any mortgage banking operations, deferred tax assets, and premises and equipment. Further, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates and have not been considered in any of these estimates.

Banking Regulation, Global Systemically Important Bank (GSIB) Surcharge [Abstract]
Regulatory Matters	Regulatory Matters The Company is 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 Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’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 Company to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1, and common equity Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets. The following tables present actual and required capital ratios as of March 31, 2022 and December 31, 2021 for the Company and the Bank under applicable Basel III Capital Rules. The minimum capital amounts presented include the minimum required capital levels as of March 31, 2022 and December 31, 2021 based on the then phased-in provisions of the Basel III Capital Rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. Actual Required for Capital Adequacy Purposes Required to be As of March 31, 2022: Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) Total Capital (to Risk Weighted Assets): Consolidated $ 1,041,638 14.96 % $ 731,146 10.50 % N/A N/A Tri Counties Bank $ 1,031,120 14.81 % $ 730,800 10.50 % $ 696,000 10.00 % Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 911,624 13.09 % $ 591,880 8.50 % N/A N/A Tri Counties Bank $ 943,960 13.56 % $ 591,600 8.50 % $ 556,800 8.00 % Common equity Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 855,180 12.28 % $ 487,431 7.00 % N/A N/A Tri Counties Bank $ 943,960 13.56 % $ 487,200 7.00 % $ 452,300 6.50 % Tier 1 Capital (to Average Assets): Consolidated $ 911,624 10.80 % $ 337,680 4.00 % N/A N/A Tri Counties Bank $ 943,960 11.18 % $ 337,635 4.00 % $ 422,043 5.00 % Actual Required for Capital Adequacy Purposes Required to be As of December 31, 2021: Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) Total Capital (to Risk Weighted Assets): Consolidated $ 893,294 15.42 % $ 608,258 10.50 % N/A N/A Tri Counties Bank $ 884,255 15.28 % $ 607,610 10.50 % $ 578,676 10.00 % Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 820,654 14.17 % $ 492,399 8.50 % N/A N/A Tri Counties Bank $ 811,713 14.03 % $ 491,875 8.50 % $ 462,941 8.00 % Common equity Tier 1 Capital (to Risk Weighted Assets): Consolidated $ 764,319 13.19 % $ 405,505 7.00 % N/A N/A Tri Counties Bank $ 811,713 14.03 % $ 405,073 7.00 % $ 376,140 6.50 % Tier 1 Capital (to Average Assets): Consolidated $ 820,654 9.88 % $ 332,205 4.00 % N/A N/A Tri Counties Bank $ 811,713 9.77 % $ 332,196 4.00 % $ 415,245 5.00 % As of March 31, 2022 and December 31, 2021, capital levels at the Company and the Bank exceed all capital adequacy requirements under the Basel III Capital Rules. Also, at March 31, 2022 and December 31, 2021, the Bank’s capital levels exceeded the minimum amounts necessary to be considered well capitalized under the current regulatory framework for prompt corrective action. The Basel III Capital Rules require for all banking organizations to maintain a capital conservation buffer 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 composed of common equity tier 1 capital, and it applies to each of the risk-based capital ratios but not the leverage ratio. At March 31, 2022, the Company and the Bank are in compliance with the capital conservation buffer requirement.

Accounting Policies [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation TriCo Bancshares (the “Company” or “we”) is a California corporation organized to act as a bank holding company for Tri Counties Bank (the “Bank”). The Company and the Bank are headquartered in Chico, California. The Bank is a California-chartered bank that is engaged in the general commercial banking business in 31 California counties. The consolidated financial statements are prepared in accordance with accounting policies generally accepted in the United States of America and general practices in the banking industry. All adjustments necessary for a fair presentation of these consolidated financial statements have been included and are of a normal and recurring nature. The financial statements include the accounts of the Company. All inter-company accounts and transactions have been eliminated in consolidation. The Company has five capital subsidiary business trusts (collectively, the “Capital Trusts”) that issued trust preferred securities, including two organized by the Company and three acquired with the acquisition of North Valley Bancorp. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1,748,000 are accounted for under the equity method and, accordingly, are not consolidated and are included in other assets on the consolidated balance sheet. See the footnote 'Junior Subordinated Debt' for additional information on borrowings outstanding.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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 and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”). The Company believes that the disclosures made are adequate to make the information not misleading.
Segment and Significant Group Concentration of Credit Risk	Segment and Significant Group Concentration of Credit Risk The Company grants agribusiness, commercial, consumer, and residential loans to customers located throughout California. The Company has a diversified loan portfolio within the business segments located in this geographical area. The Company currently classifies all its operation into one business segment that it denotes as community banking.
Geographical Descriptions	Geographical Descriptions For the purpose of describing the geographical location of the Company’s operations, the Company has defined northern California as that area of California north of, and including, Stockton to the east and San Jose to the west; central California as that area of the state south of Stockton and San Jose, to and including, Bakersfield to the east and San Luis Obispo to the west; and southern California as that area of the state south of Bakersfield and San Luis Obispo.
Reclassification	Reclassification Some items in the prior year consolidated financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year net income or shareholders’ equity.
Cash and Cash Equivalents	Cash and Cash Equivalents Net cash flows are reported for loan and deposit transactions and other borrowings. For purposes of the consolidated statement of cash flows, cash, due from banks with original maturities less than 90 days, interest-earning deposits in other banks, and Federal funds sold are considered to be cash equivalents.
Allowance for Credit Losses - Securities	Allowance for Credit Losses - Securities The Company measures expected credit losses on HTM debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on HTM debt securities totaled was considered insignificant at March 31, 2022 and is therefore excluded from the estimate of credit losses. The estimate of expected credit losses considers historical credit loss information that is adjusted for current condition and reasonable and supportable forecasts based on current and expected changes in credit ratings and default rates. Based on the implied guarantees of the U. S. Government or its agencies related to certain of these investment securities, and the absence of any historical or expected losses, substantially all qualify for a zero loss assumption.
Loans	Loans Loans that management has the intent and ability to hold until maturity or payoff are reported at principle amount outstanding, net of deferred loan fees and costs. Loans are placed in nonaccrual status when reasonable doubt exists as to the full, timely collection of interest or principal, or a loan becomes contractually past due by 90 days or more with respect to interest or principal and is not well secured and in the process of collection. When a loan is placed on nonaccrual status, all interest previously accrued but not collected is reversed against interest income. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is considered probable. Interest accruals are resumed on such loans only when they are brought fully current with respect to interest and principal and when, in the judgment of Management, the loan is estimated to be fully collectible as to both principal and interest. Accrued interest receivable is not included in the calculation of the allowance for credit losses.
Allowance for Credit Losses - Loans	Allowance for Credit Losses - Loans The ACL is a valuation account that is deducted from the loan's amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the recorded loan balance is confirmed as uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Regardless of the determination that a charge-off is appropriate for financial accounting purposes, the Company manages its loan portfolio by continually monitoring, where possible, a borrower's ability to pay through the collection of financial information, delinquency status, borrower discussion and the encouragement to repay in accordance with the original contract or modified terms, if appropriate. Management estimates the allowance balance using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. Historical credit loss experience provides the basis for the estimation of expected credit losses, which captures loan balances as of a point in time to form a cohort, then tracks the respective losses generated by that cohort of loans over the remaining life. The Company identified and accumulated loan cohort historical loss data beginning with the fourth quarter of 2008 and through the current period. In situations where the Company's actual loss history was not statistically relevant, the loss history of peers, defined as financial institutions with assets greater than three billion and less than ten billion, were utilized to create a minimum loss rate. Adjustments to historical loss information are made for differences in relevant current loan-specific risk characteristics, such as historical timing of losses relative to the loan origination. In its loss forecasting framework, the Company incorporates forward-looking information through the use of macroeconomic scenarios applied over the forecasted life of the assets. These macroeconomic scenarios incorporate variables that have historically been key drivers of increases and decreases in credit losses. These variables include, but are not limited to changes in environmental conditions, such as California unemployment rates, household debt levels and U.S. gross domestic product. A loan is considered to be collateral dependent when repayment is expected to be provided substantially through the operation or sale of the collateral. The ACL on collateral dependent loans is measured using the fair value of the underlying collateral, adjusted for costs to sell when applicable, less the amortized cost basis of the financial asset. If the value of underlying collateral is determined to be less than the recorded amount of the loan, a charge-off will be taken. Loans for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a TDR. The ACL on a TDR is measured using the same method as all other portfolio loans, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the ACL is determined by discounting the expected future cash flows at the original interest rate of the loan. PCD assets are assets acquired at a discount that is due, in part, to credit quality deterioration since origination. PCD assets are accounted for in accordance with ASC 326-20 and are initially recorded at fair value, by taking the sum of the present value of expected future cash flows and an allowance for credit losses, at acquisition. The allowance for credit losses for PCD assets is recorded through a gross-up of reserves on the balance sheet, while the allowance for acquired non-PCD assets, such as loans, is recorded through the provision for credit losses on the income statement, consistent with originated loans. Subsequent to acquisition, the allowance for credit losses for PCD loans will generally follow the same forward-looking estimation, provision, and charge-off process as non-PCD acquired and originated loans. The Company has identified the following portfolio segments to evaluate and measure the allowance for credit loss: Commercial real estate : Commercial real estate - Non-owner occupied: These commercial properties typically consist of buildings which are leased to others for their use and rely on rents as the primary source of repayment. Property types are predominantly office, retail, or light industrial but the portfolio also has some special use properties. As such, the risk of loss associated with these properties is primarily driven by general economic changes or changes in regional economies and the impact of such on a tenant’s ability to pay. Ultimately this can affect occupancy, rental rates, or both. Additional risk of loss can come from new construction resulting in oversupply, the costs to hold or operate the property, or changes in interest rates. The terms on these loans at origination typically have maturities from five fifteen Commercial real estate - Owner occupied: These credits are primarily susceptible to changes in the financial condition of the business operated by the property owner. This may be driven by changes in, among other things, industry challenges, factors unique to the operating geography of the borrower, change in the individual fortunes of the business owner, general economic conditions and changes in business cycles. When default is driven by issues related specifically to the business owner, collateral values tend to provide better repayment support and may result in little or no loss. Alternatively, when default is driven more by general economic conditions, the underlying collateral may have devalued more and thus result in larger losses in the event of default. The terms on these loans at origination typically have maturities from five fifteen Multifamily: These commercial properties are generally comprised of more than four rentable units, such as apartment buildings, with each unit intended to be occupied as the primary residence for one or more persons. Multifamily properties are also subject to changes in general or regional economic conditions, such as unemployment, ultimately resulting in increased vacancy rates or reduced rents or both. In addition, new construction can create an oversupply condition and market competition resulting in increased vacancy, reduced market rents, or both. Due to the nature of their use and the greater likelihood of tenant turnover, the management of these properties is more intensive and therefore is more critical to the preclusion of loss. Farmland: While the Company has few loans that were originated for the purpose of the acquisition of these commercial properties, loans secured by farmland represent unique risks that are associated with the operation of an agricultural businesses. The valuation of farmland can vary greatly over time based on the property's access to resources including but not limited to water, crop prices, foreign exchange rates, government regulation or restrictions, and the nature of ongoing capital investment needed to maintain the quality of the property. Loans secured by farmland typically represent less risk to the Company than other agriculture loans as the real estate typically provides greater support in the event of default or need for longer term repayment. Consumer loans : SFR 1-4 1st DT Liens: The most significant drivers of potential loss within the Company's residential real estate portfolio relate general, regional, or individual changes in economic conditions and their effect on employment and borrowers cash flow. Risk in this portfolio is best measured by changes in borrower credit score and loan-to-value. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the value of homes and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate. SFR HELOCs and Junior Liens: Similar to residential real estate term loans, HELOCs and junior liens performance is also primarily driven by borrower cash flows based on employment status. However, HELOCs carry additional risks associated with the fact that most of these loans are secured by a deed of trust in a position that is junior to the primary lien holder. Furthermore, the risk that as the borrower's financial strength deteriorates, the outstanding balance on these credit lines may increase as they may only be canceled by the Company if certain limited criteria are met. In addition to the allowance for credit losses maintained as a percent of the outstanding loan balance, the Company maintains additional reserves for the unfunded portion of the HELOC. Other: The majority of consumer loans are secured by automobiles, with the remainder primarily unsecured revolving debt (credit cards). These loans are susceptible to three primary risks; non-payment due to income loss, over-extension of credit and, when the borrower is unable to pay, shortfall in collateral value, if any. Typically non-payment is due to loss of job and will follow general economic trends in the marketplace driven primarily by rises in the unemployment rate. Loss of collateral value can be due to market demand shifts, damage to collateral itself or a combination of those factors. Credit card loans are unsecured and while collection efforts are pursued in the event of default, there is typically limited opportunity for recovery. Loss estimates are based on the general movement in credit score, economic outlook and its effects on employment and the Bank’s historical loss experience adjusted to reflect the economic outlook and the unemployment rate. Commercial and Industrial: Repayment of these loans is primarily based on the cash flow of the borrower, and secondarily on the underlying collateral provided by the borrower. A borrower's cash flow may be unpredictable, and collateral securing these loans may fluctuate in value. Most often, collateral includes accounts receivable, inventory, or equipment. Collateral securing these loans may depreciate over time, may be difficult to appraise, may be illiquid and may fluctuate in value based on the success of the business. Actual and forecast changes in gross domestic product are believed to be corollary to losses associated with these credits. Construction : While secured by real estate, construction loans represent a greater level of risk than term real estate loans due to the nature of the additional risks associated with the not only the completion of construction within an estimated time period and budget, but also the need to either sell the building or reach a level of stabilized occupancy sufficient to generate the cash flows necessary to support debt service and operating costs. The Company seeks to mitigate the additional risks associated with construction lending by requiring borrowers to comply with lower loan to value ratios and additional covenants as well as strong tertiary support of guarantors. The loss forecasting model applies the historical rate of loss for similar loans over the expected life of the asset as adjusted for macroeconomic factors. Agriculture Production: Repayment of agricultural loans is dependent upon successful operation of the agricultural business, which is greatly impacted by factors outside the control of the borrower. These factors include adverse weather conditions, including access to water, that may impact crop yields, loss of livestock due to disease or other factors, declines in market prices for agriculture products, changes in foreign exchange, and the impact of government regulations. In addition, many farms are dependent on a limited number of key individuals whose injury or death may significantly affect the successful operation of the business. Consequently, agricultural production loans may involve a greater degree of risk than other types of loans. Leases: The loss forecasting model applies the historical rate of loss for similar loans over the expected life of the asset. Leases typically represent an elevated level of credit risk as compared to loans secured by real estate as the collateral for leases is often subject to a more rapid rate of depreciation or depletion. The ultimate severity of loss is impacted by the type of collateral securing the exposure, the size of the exposure, the borrower’s industry sector, any guarantors and the geographic market. Assumptions of expected loss are conditioned to the economic outlook and the other variables discussed above. Unfunded commitments : The estimated credit losses associated with these unfunded lending commitments is calculated using the same models and methodologies noted above and incorporate utilization assumptions at time of default. The reserve for unfunded commitments is maintained on the consolidated balance sheet in other liabilities.
Accounting Standards Pending Adoption	Accounting Standards Pending Adoption FASB issued ASU 2022-02, Financial Instruments — Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures . This ASU addresses feedback received from adopters of CECL, specifically regarding accounting guidance for TDRs and disclosures of gross write-offs by year of loan origination. Accounting guidance for TDRs by creditors will be eliminated under this amendment, while also enhancing disclosure requirements for certain loan refinancing and restructurings by creditors when a borrower is experiencing financial difficulty. Amendments in this ASU are effective for the Company beginning after December 31, 2022, with early adoption permitted. Management is evaluating the extent to which this will impact the consolidated financial statements. FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides temporary optional guidance to ease the potential burden in accounting for reference rate reform by providing optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected if certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The election to apply the optional relief for existing fair value and cash flow hedge accounting relationships may be made on a hedge-by-hedge basis and across multiple reporting periods. Amendments in this ASU are effective for the Company through December 31, 2022. As the Company has an insignificant number of instruments that are applicable to this ASU, management has determined that no impact to the valuations of these instruments are applicable for financial reporting purposes.
