NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - 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 29 California counties. 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.

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. For financial reporting purposes, the Company’s investments in the Capital Trusts of $1,727,699 are accounted for under the equity method and, accordingly, are not consolidated and are included in other assets on the consolidated balance sheet. The subordinated debentures issued and guaranteed by the Company and held by the Capital Trusts are reflected as debt on the Company’s consolidated balance sheet.

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, 2019 (the “2019 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 northern and central 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 - Held to Maturity Securities

The Company measures expected credit losses on held-to-maturity debt securities on a collective basis by major security type, then further disaggregated by sector and bond rating. Accrued interest receivable on held-to-maturity (HTM) debt securities totaled $795,000 at September 30, 2020 and is 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.

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 allowance for credit losses (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 troubled debt restructuring (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.

Table of Contents

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 to ten years with amortization periods from fifteen to thirty years.

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 to ten years with amortization periods from fifteen to thirty years.

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 Adopted in 2020

On January 1, 2020, the Company adopted ASU 2016-03 Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss methodology that is referred to as the current expected credit loss (CECL) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized costs, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in certain leases. In addition, ASC 326 made changes to the accounting for available for sale debt securities. One such change is to require increases or decreases in credit losses be presented as an allowance rather than as a write-down on available for sale debt securities, based on management's intent to sell the security or likelihood the Company will be required to sell the security, before recovery of the amortized cost basis.

The Company adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for the reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company adopted ASC 326 using the prospective transition approach for financial assets purchased with credit deterioration (PCD) that were previously classified as purchase credit impaired (PCI) and accounted for under ASC 310-30. In accordance with ASC 326, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. The remaining noncredit discount (based on the adjusted amortized costs basis) will be accreted into interest income at the effective interest rate as of adoption. The Company recognized an increase in the ACL for loans totaling $18,913,000, including a reclassification of $481,000 from discounts on acquired loans to the allowance for credit losses, as a cumulative effect adjustment from change in accounting policies, with a corresponding decrease in retained earnings, net of $5,449,000 in taxes of $12,983,000. Management has separately evaluated its held-to-maturity investment securities from obligations of state and political subdivisions and determined that no loss reserves were required.

On January 1, 2020 the Company adopted ASU 2017-04, Intangibles—Goodwill and Other: Simplifying the Test for Goodwill Impairment (Topic 350), which eliminates step two of the goodwill impairment test (the hypothetical purchase price allocation used to determine the implied fair value of goodwill) when step one (determining if the carrying value of a reporting unit exceeds its fair value) is failed. Instead, entities simply will compare the fair value of a reporting unit to its carrying amount and record goodwill impairment for the amount by

which the reporting unit’s carrying amount exceeds its fair value. There was no goodwill impairment recorded during the three and nine month periods ended September 30, 2020.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted in response to the Coronavirus Disease 2019 (COVID-19) pandemic. The CARES Act provides optional temporary relief from troubled debt restructuring and impairment accounting requirements for loan modifications related to the COVID-19 pandemic made during the period from March 1, 2020 to the earlier of December 31, 2020 or 60 days after the national emergency concerning COVID-19 declared by the President terminates. Following the passage of the CARES Act legislation, the "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus" was issued by federal bank regulators, which similarly offers temporary relief from troubled debt restructuring accounting for loan payment deferrals for certain customers whose businesses are experiencing economic hardship due to Coronavirus. The Interagency Statement requires the modification event to be short-term and COVID-19 related, requiring the borrower be not more than 30 days past due as of the date the modification program was implemented, and allowing Management to apply judgement as when the modification program terminates. The ability to suspend TDR accounting under either program does not apply to any adverse impact on the credit of a borrower that is not related to the COVID-19 pandemic.

Accounting Standards Pending Adoption

FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The guidance also promotes consistent application and simplification of GAAP for other areas of Topic 740 by clarifying and amending existing guidance. ASU No. 2019-12 will be effective for the Company beginning January 1, 2021 and is not expected to have a significant impact on the Company’s 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.

Gross realized gains from the sale of investment securities totaled $7,000 during the three and nine months ended September 30, 2020, respectively. There were no gross realized losses on the sale of securities during 2020. Gross realized gains from the sale of investment securities totaled $335,000 during the three and nine months ended September 30, 2019, respectively. Gross realized losses from the sale of investment securities during the three and nine months ended September 30, 2019 totaled $228,000. Investment securities with an aggregate carrying value of $460,317,000 and $466,321,000 at September 30, 2020 and December 31, 2019, 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 September 30, 2020 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 September 30, 2020, obligations of U.S. government corporations and agencies with a cost basis totaling $856,092,000 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 September 30, 2020, the Company estimates the average remaining life of these mortgage-backed securities issued by U.S. government corporations and agencies to be approximately 2.76 years. Average remaining life is defined as the time span after which the principal balance has been reduced by half.

As of September 30, 2020, the contractual final maturity for available for sale and held to maturity investment securities is as follows:

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 September 30, 2020, 13 debt securities representing obligations of U.S. government agencies had unrealized losses with aggregate depreciation of 0.15% 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 September 30, 2020. At September 30, 2020, one (1) debt security representing obligations of states and political subdivisions had unrealized losses with aggregate depreciation of 1.33% 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 September 30, 2020 has not experienced any deterioration in credit rating. At September 30, 2020, 9 asset backed securities had unrealized losses with aggregate depreciation of 2.41% 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 September 30, 2020.

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. The following table summarizes the amortized cost of debt securities held-to-maturity at the dates indicated, aggregated by credit quality indicator:

In determining the allowance for credit losses, accruing loans with similar risk characteristics are generally evaluated collectively. 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. At both January 1, 2020, the adoption and implementation date of ASC Topic 326, and September 30, 2020, the Company utilized

a reasonable and supportable forecast period of approximately eight quarters and obtained the forecast data from publicly available sources. The Company also considered the impact of portfolio concentrations, changes in underwriting practices, imprecision in its economic forecasts, and other risk factors that might influence its loss estimation process. During the quarter ended September 30, 2020 the majority of the increase in ACL reflects potential future credit deterioration. Specifically, portfolio-wide qualitative indicators for changes in California Unemployment and US Policy uncertainty contributed to the majority of the increase in credit reserves on loans as of September 30, 2020 as compared to the trailing quarter, adding approximately $9,556,000 to the required reserves. These increases were partially offset with a reduced need for reserves for concentration risks totaling $1,472,000 and reductions in specific reserves on individually evaluated loans of $321,000. Management noted that the majority of economic forecasts utilized in the ACL calculation have continued to identify an expanded duration of the current recessionary period as caused by the global pandemic and partially offset by the governmental stimulus that has been provided to date. Management believes that the allowance for credit losses at September 30, 2020 appropriately reflected expected credit losses inherent in the loan portfolio at that date.

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.

The CARES Act, in addition to providing financial assistance to both businesses and consumers, provides financial institutions the option to temporarily suspend certain requirements under GAAP related to troubled debt restructurings for a limited period of time to account for the effects of COVID-19. The banking regulatory agencies have likewise issued guidance encouraging financial institutions to work prudently with borrowers who are, or may be, unable to meet their contractual payment obligations because of the effects of COVID-19. That guidance, with concurrence of the Financial Accounting Standards Board and provisions of the CARES Act, allow modifications made on a good faith basis in response to COVID-19 to borrowers who were generally current with their payments prior to any relief, to not be treated as troubled debt restructurings. To the extent that such modifications meet the criteria previously described, such modifications are not expected to be classified as troubled debt restructurings. The following tables show certain information regarding TDRs that occurred during the periods indicated:

The Company also modified the terms of select loans in an effort to assist borrowers that were not related to the COVID-19 pandemic. 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.

Typically if a TDR defaults during the period, the loan is then considered collateral dependent and, if it was not already considered collateral dependent, an appropriate provision will be reserved or charge will be taken. The additional provisions required resulting from default of previously modified TDR’s are noted above. Loans that defaulted within the twelve month period subsequent to modification were not considered significant for financial reporting purposes.

Note 5 - Leases

The Company records a right-of-use asset (“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 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. For operating leases existing prior to January 1, 2019, the rate for the remaining lease term as of January 1, 2019 was used. 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:

Note 8 - Shareholders’ Equity

Dividends Paid

The Bank paid to the Company cash dividends in the aggregate amounts of $6,913,000 and $7,011,000 during the three months ended September 30, 2020 and 2019, respectively and $46,361,000 and $25,361,000 during the nine months ended September 30, 2020 and 2019, respectively. The Bank is regulated by the Federal Deposit Insurance Corporation (FDIC) and the State of California Department of Business Oversight (DBO). Absent approval from the Commissioner of the DBO, 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 November 12, 2019 the Board of Directors approved the authorization to repurchase up to 1,525,000 shares of the Company's common stock (the 2019 Repurchase Plan), which approximated 5.0% 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 program is subject to change. The 2019 Repurchase Plan has no expiration date and during the year ended 2019, the Company had repurchased no shares. During the three and nine months ended September 30, 2020, the Company repurchased 0 and 813,862 shares with a market value of $0 and $24,809,000, respectively.

In connection with approval of the 2019 Repurchase Plan, the Company’s previous repurchase program adopted on August 21, 2007 (the 2007 Repurchase Plan) was terminated. There were no shares of common stock repurchased under the 2007 Repurchase Plan during 2019.

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 withholding taxes on such shares. During the three months ended September 30, 2020 and 2019, employees tendered 7,820 and 3,820 shares, respectively, of the Company’s common stock in connection with option exercises. During the nine months ended September 30, 2020 and 2019, employees tendered 12,488 and 108,492 shares, respectively, of the Company’s common stock in connection with option exercises. Employees also tendered 619 and 0 shares in connection with the tax withholding requirements of other share based awards during the three months ended September 30, 2020 and 2019, respectively, and 12,058 and 15,242 shares during the nine months period ended September 30, 2020 and 2019, respectively. In total, shares of the Company's common stock tendered had market values of $242,000 and $147,000 during the quarter ended September 30, 2020 and 2019, respectively, and $588,000 and $4,842,000 year to date September 30, 2020 and 2019, 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 2019 or 2007 Stock Repurchase Plans.

Note 9 - Stock Options and Other Equity-Based Incentive Instruments

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. 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. All grants of equity awards made during the nine months ended September 30, 2020, were made from the 2019 Plan.

Stock option activity during the nine months ended September 30, 2020 is summarized in the following table:

			Number of Shares						Option Price per Share						Weighted Average Exercise Price
Outstanding at December 31, 2019			160,500						$14.54 to $23.21						$	17.60

As of September 30, 2020 all options outstanding are fully vested and are expected to be exercised prior to expiration. The Company did not modify any option grants during 2019 or the nine months ended September 30, 2020.

Activity related to restricted stock unit awards during the nine months ended September 30, 2020 is summarized in the following table:

			Service Condition Vesting RSUs						Market Plus Service Condition Vesting RSUs
Outstanding at December 31, 2019			68,597						51,312
RSUs granted			64,036						46,416
RSUs added through dividend and performance credits			2,274						5,847
RSUs released			(31,708)						(20,265)
RSUs forfeited/expired			1,373						(1,695)
Outstanding at September 30, 2020			104,572						81,615

During the three months ended September 30, 2020 and 2019 there were no restricted stock unit awards granted under the 2019 Plan.

The 104,572 of service condition vesting RSUs outstanding as of September 30, 2020 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 104,572 of service condition vesting RSUs outstanding as of September 30, 2020 are expected to vest, and be released, on a weighted-average basis, over the next 1.60 years. The Company expects to recognize $2,782,321 of pre-tax compensation costs related to these service condition vesting RSUs between September 30, 2020 and their vesting dates. The Company did not modify any service condition vesting RSUs during 2019 or during the nine months ended September 30, 2020.

The 81,615 of market plus service condition vesting RSUs outstanding as of September 30, 2020 are expected to vest, and be released, on a weighted-average basis, over the next 2.10 years. The Company expects to recognize $1,469,701 of pre-tax compensation costs related to these RSUs between September 30, 2020 and their vesting dates. As of September 30, 2020, 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 122,423 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 2019 or during the nine months ended September 30, 2020.

Note 11 - 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 September 30,

Note 12 – Comprehensive Income

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 (OCI).

Note 13 - 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.

34

---

Table of Contents

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):

Total assets measured at fair value			$	964,563					$	2,960					$	955,403					$	6,200

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 and nine months ended September 30, 2020, or the year ended December 31, 2019.

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 September 30,			Beginning Balance						Transfers into (out of) Level 3						Change Included in Earnings						Issuances						Ending Balance
2020: Mortgage servicing rights			$	4,250					—						$	236					$	434					$	4,920
2019: Mortgage servicing rights			$	6,229					—						$	(455)					$	298					$	6,072

Nine months ended September 30, 2020			Beginning Balance						Transfers into (out of) Level 3						Change Included in Earnings						Issuances						Ending Balance
2020: Mortgage servicing rights			$	6,200					—						$	(2,258)					$	978					$	4,920
2019: Mortgage servicing rights			$	7,098					—						$	(1,652)					$	626					$	6,072

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 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.

Fair values for financial instruments are management’s estimates of the values at which the instruments could be exchanged in a transaction between willing parties. 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.

Note 14 - 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 September 30, 2020 and December 31, 2019 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 September 30, 2020 and December 31, 2019 based on the then phased-in provisions of the Basel III Capital Rules. As of January 1, 2019, the minimum required capital levels of the Basel III Capital Rules have been fully phased-in. 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.

As of September 30, 2020 and December 31, 2019, capital levels at the Company and the Bank exceed all capital adequacy requirements under the Basel III Capital Rules. Also, at September 30, 2020 and December 31, 2019, 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 September 30, 2020, the Company and the Bank are in compliance with the capital conservation buffer requirement.

Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond our control. There can be no assurance that future developments affecting us will be the same as those anticipated by management. We caution readers that a number of important factors could cause actual results to differ materially from those expressed in, or implied or projected by, such forward-looking statements.

Additional factors that could cause results to differ materially from those described above can be found in our Annual Report on Form 10-K for the year ended December 31, 2019, which is on file with the Securities and Exchange Commission (the “SEC”) and available in the “Investor Relations” section of our website, https://www.tcbk.com/investor-relations and in other documents we file with the SEC. Annualized, pro forma, projections and estimates are not forecasts and may not reflect actual results.

General

As TriCo Bancshares (referred to in this report as “we”, “our” or the “Company”) has not commenced any business operations independent of Tri Counties Bank (the “Bank”), the following discussion pertains primarily to the Bank. Average balances, including such balances used in calculating certain financial ratios, are generally comprised of average daily balances for the Company. Within Management’s Discussion and Analysis of Financial Condition and Results of Operations, interest income, net interest income, net interest yield, and efficiency ratio are generally presented on a fully tax-equivalent (“FTE”) basis. The Company believes the use of these non-generally accepted accounting principles (non-GAAP) measures provides additional clarity in assessing its results, and the presentation of these measures on a FTE basis is a common practice within the banking industry. Interest income and net interest income are shown on a non-FTE basis in the Part I - Financial Information section of this Form 10-Q, and a reconciliation of the FTE and non-FTE presentations is provided below in the discussion of net interest income.

Critical Accounting Policies and Estimates

The Company’s discussion and analysis of its financial condition and results of operations are based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those that materially affect the financial statements and are related to the adequacy of the allowance for loan losses, investments, mortgage servicing rights, fair value measurements, retirement plans and intangible assets. 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. A detailed discussion related to the Company’s accounting policies including those related to estimates on the allowance for loan losses, other than temporary impairment of investments and impairment of intangible assets, can be found in Note 1 of the consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 31, 2019.

COVID Deferrals

Following the passage of the CARES Act legislation, the "Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus" was issued by federal bank regulators, which offers temporary relief from troubled debt restructuring accounting for loan payment deferrals for certain customers whose businesses are experiencing economic hardship due to Coronavirus. The Company is closely monitoring the effects of the pandemic on our loan and deposit customers. Our management team continues to be focused on assessing the risks in our loan portfolio and working with our customers to mitigate where possible, the risk of potential losses. The Company implemented loan programs to allow certain consumers and businesses impacted by the pandemic to defer loan principal and interest payments.

The following is a summary of COVID related loan customer modifications with outstanding balances as of September 30, 2020:

															Modification Type												Deferral Term
(dollars in thousands)			Balance of Modified Loans						% of Total Category of Loans						Interest Only Deferral						Principal and Interest Deferral						90 Days						180 Days
Commercial real estate:

Agriculture production			—						—						—						—						—						—
Leases			—						—						—						—						—						—
Total modifications			$	130,938					2.71		%				92.32		%				7.68		%				2.73		%				97.27		%

Total loan modifications associated with CARES Act legislation made during the nine months ended September 30, 2020 total approximately $422.53 million of which $130.94 million remained outstanding under their modified terms as of September 30, 2020. Approximately $95.33 million and $35.61 million of the remaining balance of loans with modified terms are expected to conclude their modification period during the quarters ended December 31, 2020 and March 31, 2021, respectively. However, as long as the current pandemic and recessionary economic conditions continue, it is likely that additional borrowers may request an initial or subsequent modification to their loan terms.

The total loan modifications made under the CARES Act during the 2020 year are inclusive of seven borrowers with loan balances totaling approximately $26.52 million who requested and were granted a second modification and deferral. Six of these second modification and deferrals were for a period of three additional months and as of September 30, 2020 had concluded the second deferral period and returned to their regular payment terms. The remaining borrower whom received a second loan modification was granted a six month deferral on an outstanding loan balance of $597,000 and is scheduled to return to payment status in January 2021.

Management believes that its analysis of each borrower receiving a loan modification supports the ability of that borrower to return to their normal payment terms at the conclusion of the modification period; however, due to the fluidity of the current economic environment and the potential impact on borrowers no guarantees of that ability can be provided. As such management determined that a risk downgrade to each credit receiving a deferral modification was prudent until such time that the borrower's actual payment performance supports an upgrade to the pre-modification risk grade.

Results of Operations

The following discussion and analysis is designed to provide a better understanding of the significant changes and trends related to the Company and the Bank’s financial condition, operating results, asset and liability management, liquidity and capital resources and should be read in conjunction with the Condensed Consolidated Financial Statements of the Company and the Notes thereto located at Item 1 of this report.

Net Interest Income

The Company’s primary source of revenue is net interest income, or the difference between interest income on interest-earning assets and interest expense on interest-bearing liabilities. Following is a summary of the components of FTE net income for the periods indicated (dollars in thousands):

			Three months ended September 30,												Nine months ended September 30,
			2020						2019						2020						2019
Interest income			$	65,438					$	68,889					199,103						204,526
Interest expense			(1,984)						(4,201)						(7,798)						(11,653)
FTE adjustment			254						289						811						929
Net interest income (FTE)			$	63,708					$	64,977					$	192,116					$	193,802
Net interest margin (FTE)			3.72		%				4.44		%				4.02		%				4.48		%
Acquired loans discount accretion, net:
Amount (included in interest income)			$	1,876					$	2,360					$	6,211					$	5,919
Net interest margin less effect of acquired loan discount accretion			3.61		%				4.28		%				3.89		%				4.34		%
PPP loans yield:
Amount (included in interest income)			$	2,603					$	—					$	4,959					$	—
Net interest margin less effect of PPP loan yield			3.81		%				—		%				4.08		%				—		%
Acquired loan discount accretion and PPP loan yield, net:
Amount (included in interest income)			$	4,479					$	2,360					$	11,170					$	5,919
Net interest margin less effect of acquired loan discount accretion and PPP yields			3.69		%				4.28		%				3.88		%				4.40		%

Loans may be acquired at a premium or discount to par value, in which case, the premium is amortized (subtracted from) or accreted (added to) interest income over the remaining life of the loan. Generally, as time goes on, the effects of loan discount accretion and loan premium amortization decrease as the purchased loans mature or pay off early. Upon the early pay off of a loan, any remaining (unaccreted) discount or (unamortized) premium is immediately taken into interest income; and as loan payoffs may vary significantly from quarter to quarter, so may the impact of discount accretion and premium amortization on interest income. As a result of the uncertain economic environment and corresponding rate volatility, the prepayment rate of portfolio loans, inclusive of those acquired at a premium or discount, increased during the third quarter of 2020. During the three months ended September 30, 2020, June 30, 2020, March 31, 2020, and December 31, 2019, purchased loan discount accretion was $1,876,000, $2,587,000, $1,748,000, and $2,218,000, respectively.

Summary of Average Balances, Yields/Rates and Interest Differential

Net interest income (FTE) during the three months ended September 30, 2020 decreased $1,237,000 or 1.9% to $63,708,000 compared to $64,945,000 during the three months ended June 30, 2020. Over the same period net interest margin declined 38 basis points to 3.72% as compared to 4.10% in the trailing quarter. The decline in net interest income (FTE) was due primarily to a decline in yield on interest earning assets, which was 3.83% for the quarter ended September 30, 2020, which represents a decrease of 43 basis points over the trailing quarter and a decrease of 89 basis points over the same quarter in the prior year. The index utilized in a significant portion of the Company’s variable rate loans, Wall Street Journal Prime, remained unchanged at 3.25% during the quarter ended September 30, 2020 as it has remained at 3.25% since the quarter ended March 31, 2020, but decreased from 4.75% at December 31, 2019 and 5.00% at September 30, 2019.

The following table presents, for the three month periods indicated, information regarding the Company’s consolidated average assets, liabilities and shareholders’ equity, the amounts of interest income from average interest-earning assets and resulting yields, and the amount of interest expense paid on interest-bearing liabilities. Average loan balances include nonperforming loans. Interest income includes proceeds from loans on nonaccrual loans only to the extent cash payments have been received and applied to interest income. Yields on securities and certain loans have been adjusted upward to reflect the effect of income thereon exempt from federal income taxation at the current statutory tax rate (dollars in thousands).

The following commentary regarding net interest income, interest income and interest expense may be best understood while referencing the Summary of Average Balances, Yields/Rates and Interest Differential and the Summary of Changes in Interest Income and Expense due to Changes in Average Asset and Liability Balances and Yields Earned and Rates Paid shown above.

Net interest income (FTE) during the three months ended September 30, 2020 decreased $1,269,000 or 1.95% to $63,708,000 compared to $64,977,000 during the three months ended September 30, 2019. The overall decrease in net interest income (FTE) was due to a reduction in the average outstanding balance, and yields earned on investment securities, totaling $3,944,000 during the period. Declining interest rates continue to escalate pre-payment speeds on existing debt securities and promote new debt issuances at historically low coupon rates. As an offset, increases in average loan balances (including PPP) improved interest income by $9,350,000, however, loan yields were similarly hampered by low interest rates, resulting in declines in interest income of $8,310,000.

Net interest income (FTE) during the nine months ended September 30, 2020 decreased by $1,686,000 or 0.87% to $192,116,000 compared to $193,802,000 during the nine months ended September 30, 2019. Similar to the three month period noted above, the decrease in net interest income (FTE) is attributed primarily to declines in both the average outstanding balance, and yields earned on investment securities, totaling $9,721,000 for the nine month period ended 2020. Additionally, a reduction in loan interest rates caused a $8,829,000 decline in interest income, and declines in interest rates on cash and due from banks led to a $4,715,000 decline in interest income. As an offset, increases in average loan volume attributed to $14,647,000 in additional interest margin.

Asset Quality and Loan Loss Provisioning

The Company adopted CECL on January 1, 2020. During the three months ended September 30, 2020, the Company recorded a provision for credit losses of $7,649,000, as compared to $22,244,000 for the trailing quarter, and a reversal of provision expense of ($329,000) during the third quarter of 2019.

The following table presents details of the provision for credit losses for the periods indicated:

			Three months ended																		Nine months ended
(dollars in thousands)			September 30, 2020						June 30, 2020						March 31, 2020						September 30, 2020
Addition to allowance for credit losses			$	7,649					$	22,089					$	8,000					$	37,738
Addition to reserve for unfunded loan commitments			—						155						70						225
Total provision for credit losses			$	7,649					$	22,244					$	8,070					$	37,963

Prior to January 1, 2020 the Company accounted for the allowance for credit losses (ACL), formerly known as the allowance for loan losses under the incurred loan loss methodology. As of December 31, 2019 the allowance for loan losses was $30,616,000. Upon adoption of CECL on January 1, 2020, the Company recognized an increase in the ACL for loans totaling $18,913,000, including a reclassification of $481,000 from discounts on acquired loans to the allowance for credit losses, as a cumulative effect adjustment from change in accounting policies, with a corresponding decrease in retained earnings, net of $5,449,000 in taxes, of $12,983,000.

The allowance for credit losses (ACL) was $87,575,000 as of quarter ended September 30, 2020, a net increase of $7,836,000 over the immediately preceding quarter. 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 significant shifts in the magnitude of changes for both the unemployment and GDP factors leading up to the balance sheet date. Management noted that the majority of economic forecasts utilized in the ACL calculation have continued to identify an expanded duration of the current recessionary period as caused by the global pandemic and partially offset by the governmental stimulus that has been provided to date.

The changes in loan volume and changes in credit quality associated with levels of classified, past due and non-performing loans, in addition to changes in qualitative factors, resulted in the need for a provision for credit losses of $7,649,000 and net recoveries totaled $187,000 during the current quarter. The portfolio-wide qualitative indicators for changes in California Unemployment and US Policy uncertainty contributed to the majority of the increase in credit reserves on loans as of September 30, 2020 as compared to the trailing quarter, adding approximately $9,556,000 to the required reserves. These increases were partially offset with a reduced need for reserves for concentration risks totaling $1,472,000 and reductions in specific reserves on individually evaluated loans of $321,000.

During the nine months ended September 30, 2020 the ACL has increased by $38,046,000 or 76.8% to $87,575,000. Of that year-to-date increase, $308,000 is attributable to net recoveries; $3,175,000 is attributable to the net change in loan portfolio composition, risk grade migration and growth; while $34,563,000 is attributable to the net change in qualitative factors.

Loans past due 30 days or more decreased by $6,100,000 during the quarter ended September 30, 2020 to $10,522,000, as compared to $16,622,000 at June 30, 2020. Non-performing loans were $22,963,000 at September 30, 2020 and $20,730,000 at June 30, 2020, a slight increase compared to the $16,864,000 and $18,565,000 as of December 31, 2019 and September 30, 2019, respectively.

The Company's loan portfolio for non-classified loans (loans graded special mention or better) remains generally consistent for the quarter ended September 30, 2020, as compared to the trailing quarter June 30, 2020, representing 99.0% and 99.1% of total loans outstanding, respectively. Loans risk graded special mention increased by approximately $89,918,000 during the quarter ended September 30, 2020 as compared to the trailing quarter. These downgrades to special mention were largely focused in one relationship of eight loans totaling approximately $56,600,000, secured by several commercial real estate properties which remain current as to payment status and are believed to have more than sufficient collateral support. The downgrade is related to recent management and oversight changes within the borrowing entity. Other components of the loan population downgraded to special mention during the quarter includes approximately $7,900,000 in COVID-19 related restructured loans, shared between two relationships. Total loans greater than 30 days past due downgraded to special mention during the quarter equaled approximately $501,000.

There was one insignificant addition and no sales of other real estate owned during the three month period ended September 30, 2020. As of September 30, 2020, other real estate owned, which is included in other assets on the consolidated balance sheet, consisted of four properties with a carrying value of $2,057,000.

Non-interest income increased $1,029,000 or 7.3%  to $15,137,000 during the three months ended September 30, 2020 compared to $14,108,000 during the comparable 2019 quarter. Mortgage loan origination volume demand increased during the period ended September 30, 2020 as a result of the continued favorable interest rate environment, leading to an increase in mortgage loan originations sold into the secondary market which generated an additional $1,799,000 gain on sale of loans, as compared to the same quarter of 2019. As a partial offset, fee generating deposit account activity remains depressed as a result of the COVID-19 pandemic, declining $993,000 during the three months ended September 30, 2020 compared to the same period in 2019.

Non-interest income decreased $720,000 or 1.8% to $38,614,000 during the nine months ended September 30, 2020 compared to $39,334,000 during the comparable nine month period in 2019. Non-interest income for the nine months ended September 30, 2020 as compared to the same period in 2019 was negatively impacted by changes in deposit customer behaviors which have led to a reduction in fee generating account activity which is down $1,963,000 during the nine month period in 2020 as compared to the same period in 2019, has been partially offset by $501,000 in favorable card related activities and interchange income. In addition, the change in the fair value of the Company’s mortgage servicing assets, contributed to a $606,000 decline. Other non-interest income declined by $1,823,000, partially from decreases in the fair value of assets used to fund acquired deferred compensation plans totaling $718,000 for the nine months ended September 30, 2020 as compared to the same period 2019, as well as from an absence of one-time death benefits totaling $728,000 realized during the nine months ended September 30, 2019. The declines noted above were partially offset by $3,439,000 in gains from the sale of mortgage loans, which resulted from both increased volume and profit margins during the nine months ended September 30, 2020.

Non-interest expense increased by $370,000 or 0.8% to $46,714,000 during the three months ended September 30, 2020 as compared to $46,344,000 for the three months ended September 30, 2019. Total salary and benefit expense increased by $2,422,000 or 9.0% to $29,321,000 during the three months ended September 30, 2020 as compared to $26,899,000 for the same period in 2019. Salaries, net of deferred loan origination costs increased by $1,098,000 to $18,754,000 for the three-months ended September 30, 2020 due to a decrease in loan origination activity and therefore a reduction in deferred loan origination costs of $165,000 as well as employee severance costs of $400,000 associated with reductions in personnel. Benefits related expenses increased by $2,931,000 to $8,383,000 during the quarter primarily as a result of increases in expenses associated with retirement obligations and insurance costs. Partially offsetting this increase were declines in miscellaneous expenses, which decreased during the period by $1,099,000 or 30.7% to $2,478,000, and were specifically attributed to a $614,000 reduction in travel and outside training expenses as associated with the precautionary and restricted travel environment associated with the pandemic. Further, reductions in advertising expense totaled $489,000 or 36.0%, to $869,000 during the three months ended September 30, 2020 as compared to $1,358,000 for the same period in 2019.

Non-interest expense decreased by $1,480,000 or 1.1% to $137,013,000 during the nine months ended September 30, 2020 as compared to $138,493,000 for the same period in 2019. Reductions in advertising expenses totaling $2,157,000 or 51.1% to $2,065,000 contributed to this beneficial change, as did declines in miscellaneous expenses totaling $1,834,000 or 15.8% attributed primarily to a $1,681,000 reduction in travel and training expenses as a result of state-wide shelter-in-place restrictions and a reduction of $418,000 in third party services, which were partially offset by the indirect loan documentation and administrative costs associated with PPP lending activity. These declines were also offset by a net increase in salaries and benefits expense by $4,902,000 or 6.2% to $83,648,000 during the nine months ended September 30, 2020 as compared to $78,746,000 for the same period in 2019. While the increase in salaries was more than offset by the reductions in incentive compensation costs, increases in benefits and other compensation costs of $5,256,000 were caused by expenses associated with retirement obligations.

Income Taxes

The Company’s effective tax rate was 25.1% for the nine months ended September 30, 2020, as compared to 27.4% for the year ended December 31, 2019. The reduction in effective tax rate was made possible through the provisions of the Coronavirus Aid, Relief, and

Economic Security Act (“CARES Act”) which provided the Company with an opportunity to file amended tax returns and generate proposed refunds of approximately $805,000. Other differences between the Company's effective tax rate and applicable federal and state statutory rates are due to the proportion of non-taxable revenue and low income housing tax credits as compared to the levels of pre-tax earnings.

Financial Condition

For financial reporting purposes, the Company does not separately track the changes in assets and liabilities based on branch location or regional geography. Organic growth, inclusive of seasonal fluctuation, also contributes to the year-over-year balance sheet changes. During the most recent quarter, loan growth of $24,933,000 was primarily attributed to organic non-PPP loan originations of $22,416,000 or 2.0% of loan balances, excluding PPP, during the quarter ended September 30, 2020. Investment securities increased to $1,473,935,000, a change of $120,207,000 or 35.5% from $1,353,728,000 at June 30, 2020. The Company purchased approximately $196,118,000 in

Loan growth of $643,990,000 or 15.4% during the twelve month period ending September 30, 2020 consisted of approximately $425,947,000 from the PPP program, with the remainder of approximately $218,043,000 attributed to organic loan growth. Growth of deposit balances totaled $1,045,181,000 or 19.7% during the same comparative period. Expansion of Federal stimulus programs and the trends in consumer spending including reduced levels of business and personal travel likely attributed to the significant deposit growth during the quarter. Excess deposit proceeds have been temporarily allocated to cash and due from banks, which increased to $652,582,000 at September 30, 2020 from $259,047,000 as of September 30, 2019.

Investment Securities

Investment securities available for sale increased $192,819,000 to $1,142,957,000 as of September 30, 2020, compared to December 31, 2019. This increase is primarily supported by deposit growth and available cash reserves. Proceeds from the sale of investment securities totaled $229,000 and $125,247,000 during the nine month periods ended September 30, 2020 and 2019, respectively. Gross realized gains from the sale of investment securities totaled $7,000 during the three and nine months ended September 30, 2020, respectively.

Gross realized losses from the sale of investment securities during the three and nine months ended September 30, 2019 totaled $228,000. Sale activity in the 2020 and 2019 periods related to the repositioning of the investment securities portfolio which was necessitated by changes in the broader rate environment.

The following table presents the available for sale debt securities portfolio by major type as of September 30, 2020 and December 31, 2019:

Investment securities held to maturity decreased $64,910,000 to $310,696,000 as of September 30, 2020, as compared to December 31, 2019. This decrease is attributable to principal repayments of $26,136,000, and amortization of net purchase premiums of $332,000.

Loans

The Company concentrates its lending activities in six principal areas: commercial real estate loans, consumer loans, commercial and industrial loans, construction loans, agriculture production loans and leases. The interest rates charged for the loans made by the Company vary with the degree of risk, the size and maturity of the loans, the borrower’s relationship with the Company and prevailing money market rates indicative of the Company’s cost of funds.

The majority of the Company’s loans are direct loans made to individuals, farmers and local businesses. The Company relies substantially on local promotional activity and personal contacts by bank officers, directors and employees to compete with other financial institutions. The Company makes loans to borrowers whose applications include a sound purpose, a viable repayment source and a plan of repayment established at inception and generally backed by a secondary source of repayment.

The following table shows the Company’s loan balances, net deferred loan costs and discounts, as of the dates indicated:

In connection with the origination of these loans, the Company earned approximately $15,735,000 in loan fees, offset by deferred loan costs of approximately $763,000, the net of which will be recognized over the earlier of loan maturity, repayment or receipt of forgiveness confirmation. As of September 30, 2020 there was approximately $11,846,000 in net deferred fee income expected to be recognized. During the three and nine months ended September 30, 2020, the Company recognized $2,603,000 and $4,959,000, respectively, in interest and fees on PPP loans.

(1) The table above does not include deposit overdraft charge-offs.

Nonperforming assets increased during the three months ended September 30, 2020 $1,524,000 (6.5%) to $25,020,000 at September 30, 2020 compared to $23,496,000 at June 30, 2020. The increase in nonperforming assets during the third quarter of 2020 was primarily the result of new nonperforming loans of $6,948,000, which were partially offset by pay-downs of $5,207,000 and write-downs of $217,000.

Non performing loans added during the third quarter of 2020 were primarily within commercial real estate, with non-owner occupied adding $2,461,000 and owner occupied additions totaling $1,397,000. Management believes these loans are well-secured as of September 30, 2020. Further, management is actively engaged in the collection and recovery efforts for all nonperforming assets and believes that the specific loan loss reserves associated with these loans is sufficient as of September 30, 2020.

Loan charge-offs during the three months ended September 30, 2020

In the third quarter of 2020, the Company recorded $136,000 in loan charge-offs and $58,000 in deposit overdraft charge-offs less $334,000 in loan recoveries and $47,000 in deposit overdraft recoveries resulting in $187,000 of net recoveries. Loan charge-offs were not concentrated within any single loan or borrower relationship and were comprised entirely of individual charges of less than $100,000 each.

(1) The table above does not include deposit overdraft charge-offs.

Nonperforming assets increased during the first nine months of 2020 by $5,615,000 (28.9%) to $25,020,000 at September 30, 2020 compared to $19,405,000 at December 31, 2019. The increase in nonperforming assets during the third quarter of 2020 was primarily the result of new nonperforming loans of $14,752,000, which were partially offset by pay-downs of $7,834,000 and write-downs of $1,303,000.

Loan charge-offs during the nine months ended September 30, 2020

During the nine months ended September 30, 2020, the Company recorded $952,000 in loan charge-offs and $243,000 in deposit overdraft charge-offs less $1,344,000 in loan recoveries and $159,000 in deposit overdraft recoveries resulting in $308,000 of net recoveries for the year to date period.

For additional information regarding the allowance for loan losses, including changes in specific, formula, and environmental factors allowance categories, see “Asset Quality and Loan Loss Provisioning” at “Results of Operations”, above. Based on the current conditions of the loan portfolio, management believes that the $87,575,000 allowance for loan losses at September 30, 2020 is adequate to absorb probable losses inherent in the Bank’s loan portfolio. No assurance can be given, however, that adverse economic conditions or other

Deposits

During the three and nine months ended September 30, 2020, the Company’s deposits increased $92,330,000 and $973,594,000, respectively, to $6,340,588,000. Included in the September 30, 2020 and December 31, 2019 certificate of deposit balances are $30,000,000, respectively, from the State of California. The Company participates in a deposit program offered by the State of California whereby the State may make deposits at the Company’s request subject to collateral and creditworthiness constraints. The negotiated rates on these State deposits are generally more favorable than other wholesale funding sources available to the Company.

Off-Balance Sheet Arrangements

See Note 7 to the condensed consolidated financial statements at Item 1 of Part I of this report for information about the Company’s commitments and contingencies including off-balance-sheet arrangements.

Capital Resources

The current and projected capital position of the Company and the impact of capital plans and long-term strategies are reviewed regularly by Management.

On November 12, 2019 the Board of Directors approved the authorization to repurchase up to 1,525,000 shares of the Company's common stock (the 2019 Repurchase Plan), which approximates 5.0% 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 program is subject to change. The 2019 Repurchase Plan has no expiration date. During the three and nine months ended September 30, 2020, the Company repurchased zero and 813,862 shares with a market value of $0 and $7,669,000, respectively, under the 2019 Repurchase Plan.

The Company’s primary capital resource is shareholders’ equity, which was $902,262,000 at September 30, 2020. This amount represents an increase of $16,576,000 during the quarter ended September 30, 2020 primarily as a result of an increase in accumulated other comprehensive income of $4,957,000, partially offset by $6,549,000 in cash dividends paid on common stock. The Company’s ratio of equity to total assets was 12.1% and 14.0% as of September 30, 2020 and December 31, 2019, respectively. We believe that the Company and the Bank were in compliance with applicable minimum capital requirements set forth in the final Basel III Capital rules as of September 30, 2020. The following summarizes the Company’s ratios of capital to risk-adjusted assets as of the dates indicated:

			September 30, 2020												December 31, 2019
			Ratio						Minimum Regulatory Requirement						Ratio						Minimum Regulatory Requirement
Total capital			15.2		%				10.5		%				15.1		%				9.3		%
Tier I capital			14.0		%				8.5		%				14.4		%				7.3		%
Common equity Tier 1 capital			12.9		%				7.0		%				13.3		%				5.8		%
Leverage			10.0		%				4.0		%				11.6		%				4.0		%

See Note 8 and Note 14 to the condensed consolidated financial statements at Item 1 of Part I of this report for additional information about the Company’s capital resources.

Table of Contents

As of September 30, 2020, we had an effective shelf registration statement on file with the Securities and Exchange Commission that allows us to issue various types of debt securities, as well as common stock, preferred stock, warrants, depositary shares representing fractional interest in shares of preferred stock, purchase contracts and units from time to time in one or more offerings. Each issuance under the shelf registration statement will require the filing of a prospectus supplement identifying the amount and terms of the securities to be issued. The registration statement does not limit the amount of securities that may be issued thereunder. Our ability to issue securities is subject to market conditions and other factors including, in the case of our debt securities, our credit ratings and compliance with the covenants in our credit agreement.

Liquidity

The Company’s principal source of asset liquidity is cash at the Federal Reserve Bank of San Francisco (“Federal Reserve”) and other banks and marketable investment securities available for sale. As of September 30, 2020, Federal Reserve cash reserve ratios have been temporarily reduced to zero as a response to the COVID-19 pandemic. The Company’s profitability during the first nine months of 2020 generated cash flows from operations of $78,584,000 compared to $76,266,000 during the first nine months of 2019. Net cash used by investing activities was $639,947,000 for the nine months ended September 30, 2020, compared to net cash from investing activities of $46,204,000 during the nine months ending 2019. Financing activities provided $937,438,000 during the nine months ended September 30, 2020, compared to $90,956,000 used during the nine months ended September 30, 2019. Deposit balance changes increased available liquidity by $973,594,000 during the nine months ended September 30, 2020, compared to a decrease of $71,059,000 for financing activity during the same period in 2019. Dividends paid used $19,758,000 and $18,285,000 of cash during the nine months ended September 30, 2020 and 2019, respectively. The Company’s liquidity is dependent on dividends received from the Bank. Dividends from the Bank are subject to certain regulatory restrictions.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk

Based on the changes in interest rates occurring subsequent to December 31, 2019, the following update of the Company’s assessment of market risk as of September 30, 2020 is being provided. These updates and changes should be read in conjunction with the additional quantitative and qualitative disclosures in our Annual Report on Form 10-K for the year ended December 31, 2019.

Subsequent to December 31, 2019, declines in several market interest rates, including many rates that serve as reference indices for variable rate loans declined markedly from previous levels. As of December 31, 2019 the Company's loan portfolio consisted of approximately $4,346,723,000 in outstanding principal with a weighted average rate of 4.89%. As of September 30, 2020 the Company's loan portfolio consisted of approximately $4,869,000,000 in outstanding principal with a weighted average coupon rate of 4.34%, inclusive of the PPP program loans. Excluding these loans, the Company's loan portfolio has approximately $4,431,000,000 outstanding with a weighted average coupon rate of 4.66% as of September 30, 2020. Included in this September 30, 2020 loan total exclusive of PPP loans, are variable rate loans totaling $2,991,000,000 of which 87.7% or $2,622,000,000 were at their floor rate. The remaining variable rate loans totaling $369,000,000, which carried a weighted average coupon rate of 5.07% as of September 30, 2020, are subject to further rate adjustment. If those remaining variable rate loans were to collectively, through future rate adjustments, be reduced to their respective floors, they would have a weighted average coupon rate of approximately 4.36% which would result in the reduction of the weighted average coupon rate of the total loan portfolio, exclusive of PPP loans, from 4.66% to approximately 4.61%.

As of September 30, 2020 the overnight Federal funds rate, the rate primarily used in these interest rate shock scenarios, was less than 1.00%. Based on the historical nature of these rates in the United States not falling below zero, management believes that a shock scenario that reduces interest rates below zero would not provide meaningful results and therefore, have not been modeled. These scenarios assume that 1) interest rates increase or decrease evenly (in a “ramp” fashion) over a twelve-month period and remain at the new levels beyond twelve months or 2) that interest rates change instantaneously (“shock”). The simulation results shown below assume no changes in the structure of the Company’s balance sheet over the twelve months being measured.

The following table summarizes the estimated effect on net interest income and market value of equity to changing interest rates as measured against a flat rate (no interest rate change) instantaneous shock scenario over a twelve month period utilizing the Company's specific mix of interest earning assets and interest bearing liabilities as of September 30, 2020.

Item 4.    Controls and Procedures

The Company’s management, including its Chief Executive Officer and Chief Financial Officer, have evaluated the effectiveness of the Company’s disclosure controls and procedures as of September 30, 2020. Disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are controls and procedures designed to reasonably assure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported on a timely basis. Disclosure controls are also designed to reasonably assure that such information is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Based upon their evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2020.

During the three and nine months ended September 30, 2020, there were no changes in our internal controls or in other factors that have materially affected or are reasonably likely to materially affect our internal controls over financial reporting.

PART II – OTHER INFORMATION

Item 1 - Legal Proceedings

Due to the nature of our business, we are involved in legal proceedings that arise in the ordinary course of our business. While the outcome of these matters is currently not determinable, we do not expect that the ultimate costs to resolve these matters will have a material adverse effect on our consolidated financial position, results of operations, or cash flows.

Item 1A - Risk Factors

In addition to the other information set forth in this Form 10-Q, you should carefully consider the risk factors that appeared under Item 1A, "Risk Factors" in the Company’s 2019 Annual Report on Form 10-K. The following represents a material change in our risk factors from those disclosed in the Company's 2019 Annual Report on Form 10-K.

The novel coronavirus, COVID-19, has and will likely continue to adversely affect our business, financial condition, results of operations and our liquidity for the foreseeable future. The effects depend on future developments, which are highly uncertain and are difficult to predict.

Global health concerns relating to the COVID-19 pandemic and related government actions taken to reduce the spread of the virus have created significant economic uncertainty and reduced economic activity, including within our market areas. On March 13, 2020, a National Emergency relating to the virus was declared. Governmental authorities, include the State of California and many of its local governments, have implemented numerous measures to try to contain the virus, such as travel bans and restrictions, “stay at home” orders and business limitations and shutdowns. These measures have negatively impacted consumer and business spending. Businesses nationwide and in the regions and communities in which we operate have laid off and furloughed significant numbers of employees, leading to record levels of unemployment. These conditions have significantly adversely affected our borrowers, including many different types of small and mid-sized businesses within our client base, particularly those in the gas station, retail, hotel, hospitality and food, beverage, and elective healthcare industries, among many others. The United States government has taken steps to attempt to mitigate some of the more severe anticipated economic effects of the virus, including the passage of the CARES Act, but there can be no assurance that such steps will be effective or achieve their desired results in a timely fashion.

The Federal Reserve lowered the primary credit rate by 50 and 100 basis points on March 3 and March 15, 2020, respectively, for a total of 150 basis points to 0.25% to mitigate the effects of the COVID-19 pandemic and to support the liquidity and stability of banking institutions as they serve the increased demand for credit. We expect a long duration of reduced interest rates to negatively impact our net interest income, margin, cost of borrowing and future profitability and to have a material adverse effect on our financial results for the remainder of 2020.

The outbreak has adversely impacted and is likely to further adversely impact our operations and the operations of our borrowers, customers and business partners. In particular, we may experience losses and other adverse effects due to a number of factors impacting us or our borrowers, customers or business partners, including but not limited to:

•increased loan deferrals, loan delinquencies and subsequent credit losses resulting from the weakened financial condition of our borrowers as a result of the outbreak and related governmental actions;

•the negative effect on earnings resulting from the Bank modifying loans and agreeing to loan payment deferrals due to the COVID-19 crisis;

•declines in the value of collateral securing loans we have made;

•court closures and temporary foreclosure and eviction protection laws, even when a customer is in breach of its obligations to us, are likely to restrict our ability to realize on the value of collateral;

•disruption in the businesses of third parties upon who we rely, including outages at network providers and other service providers and suppliers;

•increased cyber and payment fraud risk, as cybercriminals attempt to profit from the disruption, given increased online and remote activity;

•decreased loan growth as a result of diminished demand or increased levels of prepayment;

•decreased interest and non-interest income;

•continued decreased demand for certain bank products and services;

•declines in the value of securities we own, credit ratings downgrades, deterioration in issuers’ financial condition or a decline in the liquidity for debt securities;

•operational failures due to changes in our normal business practices necessitated by the outbreak and related governmental actions;

63

Table of Contents

•reduced workforce numbers or capacity which may be caused by, but not limited to, illness, quarantine, stay at home or other government mandates, or difficulties transitioning back to an in-office environment;

•continued high levels of unemployment due to decreased operations or closures of businesses could have a negative impact on our customer’s ability to repay their loans as well as a decrease in the customer deposit base as they use their savings to pay current expenses;

•laws related to benefits and the treatment of employees, for example, mandating coverage of certain COVID-19 related testing and treatment, mandating additional paid or unpaid leave or expanding workers compensation coverage;

•volatile market prices of investment securities, including the valuation of our common stock;

•unavailability of key personnel or a significant number of our employees due to the effects and restrictions of a COVID-19 outbreak within our market area;

•a protracted COVID-19 pandemic could further negatively affect the carrying amount of our goodwill, indefinite-lived intangibles and long-lived assets and result in realized losses on our financial assets, which would adversely impact our results of operations and the ability of certain of our bank subsidiary to pay dividends to us;

•increased risk of litigation and governmental and regulatory scrutiny as a result of the effects of the COVID-19 pandemic on market and economic conditions and actions governmental authorities take in response to those conditions; and

•additional costs to remedy damages, losses or disruption caused by such events

These factors may remain prevalent for a significant period of time and may continue to adversely affect our business, results of operations and financial condition even after the COVID-19 outbreak has subsided.

The spread of COVID-19 has caused us to modify our business practices (including restricting employee travel, and developing work from home and social distancing plans for our employees), and we may take further actions as may be required by government authorities or as we determine are in the best interests of our employees, customers and business partners. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus or will otherwise be satisfactory to government authorities.

The extent to which the coronavirus outbreak impacts our business, results of operations and financial condition will depend on future developments, which are highly uncertain and are difficult to predict, including, but not limited to, the duration and spread of the outbreak, its severity, the actions to contain the virus or treat its impact, and how quickly and to what extent normal economic and operating conditions can resume. The longer the public health crisis lasts, and the greater its severity, the greater the likely material adverse impact on the economy, our customers and our business and financial performance. Even after the COVID-19 outbreak has subsided, we may continue to experience materially adverse impacts to our business as a result of the virus’s economic impact and any recession that has occurred or may occur in the future.

In addition, the United States Government and its related entities are incurring unprecedented debt levels to support the United States Economy. This level of debt may not be sustainable, may cause inflationary pressures and increases risks to fund the balance sheet if international investors no longer purchase United States Securities.

There are no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have, and, as a result, it is not possible to predict the extent, severity or duration of these conditions or when normal economic and operating conditions will resume. However, we believe the effects will have (at least in the short term) a material impact on our results of operations and heighten many of our known risks described in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2019.

Our Bank's participation in the Paycheck Protection Program could expose us to additional risks.

Federal and state governments have enacted laws intending to stimulate the economy in light of the business and market disruptions related to COVID-19. President Trump signed into law three economic stimulus packages, including the $2.0 trillion Coronavirus Relief and Economic Security Act on March 26, 2020, which, among other things, initiated the PPP. On April 16, 2020, the original $349.0 billion of funding under the PPP was exhausted, and on April 24, 2020, the Federal Government allocated an additional $310.0 billion to the program. Our Bank participated as a lender in both the initial and second rounds of the PPP, which was designed to help small businesses maintain their workforce during the COVID-19 pandemic. As of September 30, 2020, we have $425.9 million of loans outstanding under the Payment Protection Program.

We understand that these loans are fully guaranteed by the SBA and believe the majority of these loans will be forgiven. However, there can be no assurance that the borrowers will use or have used the funds appropriately or will have satisfied the staffing or payment requirements to qualify for forgiveness in whole or in part. Any portion of the loan that is not forgiven must be repaid by the borrower.

guidance regarding operation of the PPP, the SBA may deny its liability under the guaranty, reduce the amount of the guaranty, or, if we have already been paid under the guaranty, seek recovery from us of any loss related to the deficiency.

Since the opening of the PPP, several other large banks have been subject to litigation regarding the process and procedures that such banks used in processing applications for the PPP. We may be exposed to the risk of similar litigation, from both customers and non-customers that approached us regarding PPP loans, regarding its processes and procedures used in processing applications for the PPP. If any such litigation is filed against us and is not resolved in a manner favorable to the Bank, it may result in significant financial liability or adversely affect our reputation. In addition, litigation can be costly, regardless of outcome. Any financial liability, litigation costs or reputational damage caused by PPP related litigation could have a material adverse impact on our business, financial condition and results of operations.
