NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)
Note 1: Basis of Presentation
The consolidated financial statements include the accounts of Bancorp, a bank holding company, and its wholly-owned bank subsidiary, Bank of Marin, a California state-chartered commercial bank. References to “we,” “our,” “us” mean Bancorp and the Bank that are consolidated for financial reporting purposes. The accompanying unaudited consolidated interim financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been condensed or omitted pursuant to those rules and regulations.
Although we believe that the disclosures are adequate and the information presented is not misleading, we suggest that these interim financial statements be read in conjunction with the annual financial statements and the notes thereto included in our 2021 Annual Report on Form 10-K. In the opinion of management, the unaudited consolidated financial statements reflect all adjustments, which are necessary for a fair presentation of the consolidated financial position, the results of operations, changes in comprehensive income, changes in stockholders’ equity, and cash flows for the periods presented. All material intercompany transactions have been eliminated. The results of these interim periods may not be indicative of the results for the full year or for any other period.
The following table shows: 1) weighted average basic shares, 2) potentially dilutive weighted average common shares related to stock options and unvested restricted stock awards, and 3) weighted average diluted shares. Basic earnings per share (“EPS”) are calculated by dividing net income by the weighted average number of common shares outstanding during each period, excluding unvested restricted stock awards. Diluted EPS are calculated using the weighted average number of potentially dilutive common shares. The number of potentially dilutive common shares included in the quarterly diluted EPS is computed using the average market prices during the three months included in the reporting period under the treasury stock method. The number of potentially dilutive common shares included in year-to-date diluted EPS is a year-to-date weighted average of potentially dilutive common shares included in each quarterly diluted EPS computation. In computing diluted EPS, we exclude anti-dilutive shares such as options whose exercise prices exceed the current common stock price, as they would not reduce EPS under the treasury method. We have two forms of outstanding common stock: common stock and unvested restricted stock awards. Holders of unvested restricted stock awards receive non-forfeitable dividends at the same rate as common shareholders and they both share equally in undistributed earnings. Under the two-class method, the difference in EPS is nominal for these participating securities.

Note 2: Recently Adopted and Issued Accounting Standards
Accounting Standards Not Yet Effective
In March 2020, the FASB issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848). The amendments in this ASU are elective and provide optional guidance for a limited period of time to ease the potential burden of accounting for, or recognizing the effects of reference rate reform. The amendments in this ASU provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of
Page-7

reference rate reform. The amendments in this ASU may be elected as of March 12, 2020 through December 31, 2022. An entity may choose to elect the amendments in this update at an interim period subsequent to March 12, 2020 with adoption methods varying based on transaction type. We have elected not to apply amendments at this time and to assess the applicability of this ASU to us as we continue to monitor guidance for reference rate reform from FASB and its impact on our financial condition and results of operations.
In January 2021, the FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848). The main amendments in this ASU intend to clarify certain optional expedients and scope of derivative instruments. The amendments are elective and effective immediately upon issuance of this ASU. Amendments may be elected through December 31, 2022. As of June 30, 2022, we had four interest rate swap contracts with notional values totaling $12.5 million indexed to LIBOR that will either be subject to the fall-back index rate stipulated by the ISDA protocol or modified to other reference rates such as Prime or SOFR as mutually agreed by our counterparty an us. We have not elected to apply the amendments at this time and will continue to assess the applicability of this ASU to us as we monitor guidance for reference rate reform from FASB and its impact on our financial condition and results of operations.
In October 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities From Contracts With Customers (Topic 805). The amendments address diversity in accounting practices and require acquiring companies to apply ASC 606, Revenue from Contracts with Customers to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination, as opposed to other methods such as fair value. The amendments improve comparability after the business combination by providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination. The amendments are to be applied prospectively to business combinations occurring on or after December 15, 2022 and early adoption is permitted. In the event of a future business combination, we will assess the impact of the ASU on our financial condition and results of operations.
In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendment eliminates the recognition measurement guidance for troubled debt restructured ("TDR") loans, and instead requires an entity to evaluate whether a modification represents a new loan or a continuation of an existing loan in accordance with ASC Topic 310-20, Receivables - Nonrefundable Fees and Other Costs. In addition, the amendment requires that an entity include in its vintage disclosures the current period-gross loan charge-offs by year of origination. The amendments are effective for years beginning after December 15, 2022, and should be applied prospectively, except that an entity has the option to apply a modified retrospective method for TDR loans, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. An entity may elect to early adopt each of the amendments separately. As such, we early adopted the current period charge-off disclosures in the first quarter of 2022 and intend to adopt the loan modification amendments when effective in the first quarter of 2023. Neither the early adoption of the amendments related to gross charge-off disclosures nor the future adoption of the TDR amendments had or will have a material impact on our financial condition or results of operations.
In March 2022, the FASB issued ASU No. 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method. Among other things, the ASU renames the "last-of-layer" method to the "portfolio layer" method and makes fair value hedging more accessible for hedge accounting of interest rate risk for portfolios and financial assets. For example, the guidance permits an entity to apply the same portfolio hedging method to both prepayable and non-prepayable financial assets, thereby providing for consistency between accounting for similar hedges. The amendments are effective for years beginning after December 15, 2022. The adoption of the amendments will not affect our existing hedge accounting, disclosures, financial condition or results of operations.
In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. The amendment reduces diversity in practice by clarifying that a separate contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. In addition, this ASU provided amended examples to illustrate that a restriction that is a characteristic of the equity security, which market participants would take into account when pricing them, would be considered in measuring fair value. This ASU also introduces new disclosure requirements. The amendments are effective prospectively for years beginning after December 15, 2023. Early adoption is permitted for both interim and annual financial statements. As discussed in Note 4, Investment Securities, we hold Visa Inc. Class B common stock that is legally restricted from resale to non-member banks of Visa U.S.A. until the covered litigation against Visa Inc. is settled. While the adoption of the amendments may require additional disclosures, we do not anticipate that it will impact our financial condition or results of operations.

Note 3: Fair Value of Assets and Liabilities
Fair Value Hierarchy and Fair Value Measurement
We group our assets and liabilities that are measured at fair value into three levels within the fair value hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
Level 1: Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2: Valuations are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuations for which all significant assumptions are observable or can be corroborated by observable market data.
Level 3: Valuations are based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Values are determined using pricing models and discounted cash flow models and may include significant management judgment and estimation.
Transfers between levels of the fair value hierarchy are recognized through our monthly and/or quarterly valuation process in the reporting period during which the event or circumstances that caused the transfer occurred. No such transfers occurred in the years presented.
The following table summarizes our assets and liabilities that were required to be recorded at fair value on a recurring basis.

Available-for-sale securities are recorded at fair value on a recurring basis. When available, quoted market prices (Level 1) are used to determine the fair value of available-for-sale securities. Level 1 securities include U.S. Treasury securities. If quoted market prices are not available, we obtain pricing information from a reputable third-party service provider, who may utilize valuation techniques that use current market-based or independently sourced parameters, such as bid/ask prices, dealer-quoted prices, interest rates, benchmark yield curves, prepayment speeds, probability of default, loss severity and credit spreads (Level 2). Level 2 securities include asset-backed securities, obligations of state and political subdivisions, U.S. agencies or government-sponsored agencies' debt securities, mortgage-backed securities, government agency-issued, and corporate bonds. As of June 30, 2022 and December 31, 2021, there were no Level 3 securities.
Held-to-maturity securities may be written down to fair value as a result of an other-than-temporary impairment, and we did not record any write-downs during the six months ended June 30, 2022 or June 30, 2021. Fair value of held-to-maturity securities is determined using the same techniques discussed above for available-for-sale securities.
On a recurring basis, derivative financial instruments are recorded at fair value, which is based on the income approach using observable Level 2 market inputs, reflecting market expectations of future interest rates as of the measurement date. Standard valuation techniques are used to calculate the present value of the future expected cash flows assuming an orderly transaction. Valuation adjustments may be made to reflect both our own credit risk and the counterparties’ credit risk in determining the fair value of the derivatives. Level 2 inputs for the valuations are limited to observable market prices for London Interbank Offered Rate ("LIBOR") and Overnight Index Swap ("OIS") rates (for the very short term), quoted prices for LIBOR futures contracts, observable market prices for LIBOR and OIS swap rates, and one-month and three-month LIBOR basis spreads at commonly quoted intervals. Mid-market pricing of the inputs is used as a practical expedient in the fair value measurements. We project spot rates at reset days specified by each swap contract to determine future cash flows, then discount to present value using OIS curves as of the measurement date. When the value of any collateral placed with counterparties is less than the interest rate derivative liability, a credit valuation adjustment ("CVA") is applied to reflect the credit risk we pose to counterparties. We have used the spread between the Standard & Poor's BBB rated U.S. Bank Composite rate and LIBOR for the closest maturity term corresponding to the duration of the swaps to derive the CVA. A similar credit risk adjustment, correlated to the credit standing of the counterparty, is made when collateral posted by the counterparty does not fully cover their liability to us. For further discussion on our methodology in valuing our derivative financial instruments, refer to Note 9, Derivative Financial Instruments and Hedging Activities.
Certain financial assets may be measured at fair value on a non-recurring basis. These assets are subject to fair value adjustments that result from the application of the lower of cost or fair value accounting or write-downs of individual assets, such as individually analyzed loans that are collateral dependent and other real estate owned ("OREO").
OREO represents collateral acquired through foreclosure and is initially recorded at fair value as established by a current appraisal of the collateral. Subsequent to foreclosure, OREO is carried at the lower of cost or fair value, less estimated costs to sell. OREO values are reviewed on an ongoing basis and any subsequent decline in fair value is recorded as a foreclosed asset expense in the current period. The value of OREO is classified as Level 3. Our current OREO resulted from the American River Bankshares ("ARB") merger in 2021.
The following table presents the carrying value of assets measured at fair value on a non-recurring basis and that were held in the consolidated statements of condition at each respective period end, by level within the fair value hierarchy as of June 30, 2022 and December 31, 2021.

Disclosures about Fair Value of Financial Instruments
The table below is a summary of fair value estimates for financial instruments as of June 30, 2022 and December 31, 2021, excluding financial instruments recorded at fair value on a recurring basis (summarized in the first table in this note). The carrying amounts in the following table are recorded in the consolidated statements of condition under the indicated captions. Further, we have not disclosed the fair value of financial instruments specifically excluded from disclosure requirements such as bank-owned life insurance policies ("BOLI"), lease obligations and non-maturity deposit liabilities. Additionally, we held shares of Federal Home Loan Bank ("FHLB") of San Francisco stock and Visa Inc. Class B common stock, both recorded at cost, as there was no impairment or changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer as of June 30, 2022 or December 31, 2021. The values are discussed in Note 4, Investment Securities.

Fair value of loans is based on exit price techniques and obtained from an independent third-party that uses its proprietary valuation model and methodology and may differ from actual price from a prospective buyer. The discounted cash flow valuation approach reflects key inputs and assumptions that are unobservable, such as loan probability of default, loss given default, prepayment speed, and market discount rates.
Fair value of fixed-rate time deposits is estimated by discounting future contractual cash flows using discount rates that reflect the current observable market rates offered for time deposits of similar remaining maturities.
The value of off-balance-sheet financial instruments is estimated based on the fee income associated with the commitments, which in the absence of credit exposure, is considered to approximate their settlement value. The fair value of commitment fees was not material as of June 30, 2022 or December 31, 2021.
Note 4: Investment Securities

Management measures expected credit losses on held-to-maturity securities collectively by major security type with each type sharing similar risk characteristics, and considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. With regard to MBSs and CMOs issued or guaranteed by the GSEs, and SBA-backed securities, we expect to receive all the contractual principal and interest on these securities as such securities are backed by the full faith and credit of and/or guaranteed by the U.S. government. Accordingly, no allowance for credit losses has been recorded for these securities. With regard to securities issued by states and political subdivisions and corporate bonds, management considers: (i) issuer and/or guarantor credit ratings, (ii) historical probability of default and loss given default rates for given bond ratings and remaining maturity, (iii) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities, (iv) internal credit review of the financial information, and (v) whether or not such securities have credit enhancements such as guarantees, contain a defeasance clause, or are pre-refunded by the issuers. Based on the comprehensive analysis, no credit losses are expected.
The following table summarizes the amortized cost of our portfolio of held-to-maturity securities issued by states and political subdivisions and corporate bonds by Moody's and/or Standard & Poor's bond ratings as of June 30, 2022.

As part of our ongoing review of our investment securities portfolio, we reassessed the classification of certain securities issued by government sponsored agencies. In March 2022, we transferred $357.5 million of these securities from available-for-sale to held-to-maturity at fair value. We intend and have the ability to hold these securities to maturity. The net unrealized pre-tax loss of $14.8 million that remained in accumulated other comprehensive loss is accreted over the remaining lives of the securities.
The amortized cost a nd fair value of investment debt securities by contractual maturity at June 30, 2022 and December 31, 2021 are shown below. Expected maturities may differ from contractual maturities if the issuers of the securities have the right to call or prepay obligations with or without call or prepayment penalties.

As of June 30, 2022, the investment portfolio included 18 investment securities that had been in a continuous loss position for twelve months or more and 391 investment securities that had been in a loss position for less than twelve months.
Securities issued by government-sponsored agencies, such as FNMA and FHLMC, usually have implicit credit support by the U.S. federal government. However, since 2008, FNMA and FHLMC have been under government conservatorship and, therefore, contractual cash flows for these investments carry explicit guarantees by the U.S. federal government. Securities issued by the SBA and GNMA have explicit credit guarantees by the U.S. federal government, which protects us from credit losses on the contractual cash flows of the securities.
Our investment in obligations of state and political subdivisions bonds are deemed credit worthy after our comprehensive analysis of the issuers' latest financial information, credit ratings by major credit agencies, and/or credit enhancements.
At June 30, 2022, management determined that it did not intend to sell any investment securities with unrealized losses, and it is more likely than not that we will not be required to sell securities with unrealized losses before recovery of their amortized cost. No allowances for credit losses have been recognized on available-for-sale securities in an unrealized loss position, as management does not believe any of the securities are impaired due to reasons of credit quality at June 30, 2022.
Non-Marketable Securities Included in Other Assets
FHLB Capital Stock
As a member of the FHLB, we are required to maintain a minimum investment in FHLB capital stock determined by the Board of Directors of the FHLB. The minimum investment requirements can increase in the event we increase our total asset size or borrowings with the FHLB. Shares cannot be purchased or sold except between the FHLB and its members at the $100 per share par value. We held $16.7 million of FHLB stock included in other assets on the consolidated statements of condition at both June 30, 2022 and December 31, 2021. The carrying amounts of
Page-15

these investments are reasonable estimates of fair value because the securities are restricted to member banks and they do not have a readily determinable market value. Based on our analysis of FHLB's financial condition and certain qualitative factors, we determined that the FHLB stock was not impaired at June 30, 2022 and December 31, 2021. On July 28, 2022, FHLB announced a cash dividend for the first quarter of 2022 at an annualized dividend rate of 6.00% to be distributed in mid-August 2022. Cash dividends paid on FHLB capital stock are recorded as non-interest income.
VISA Inc. Class B Common Stock
As a member bank of Visa U.S.A., we held 10,439 shares of Visa Inc. Class B common stock at June 30, 2022 and December 31, 2021. These shares have a carrying value of zero and are restricted from resale to non-member banks of Visa U.S.A. until their conversion into Class A (voting) shares upon the termination of Visa Inc.'s Covered Litigation escrow account. Because of the restriction and the uncertainty on the conversion rate to Class A shares, these shares lack a readily determinable fair value. When converting this Class B common stock to Class A common stock based on the estimated conversion rate of 1.6059 and 1.6181 at June 30, 2022 and December 31, 2021, and the closing stock price of Class A shares at those respective dates, the converted value of our shares of Class B common stock would have been $3.3 million and $3.7 million at June 30, 2022 and December 31, 2021, respectively. The conversion rate is subject to further adjustment upon the final settlement of the covered litigation against Visa Inc. and its member banks. As such, the fair value of these Class B shares can differ significantly from their converted values. For further information, refer to Note 8, Commitments and Contingencies.
Low Income Housing Tax Credits
We invest in low-income housing tax credit funds as a limited partner, which totaled $2.7 million and $3.0 million recorded in other assets as of June 30, 2022 and December 31, 2021, respectively. In the first six months of 2022, we recognized $317 thousand of low-income housing tax credits and other tax benefits, offset by $267 thousand of amortization expense of low-income housing tax credit investment, as a component of income tax expense. As of June 30, 2022, our unfunded commitments for these low-income housing tax credit funds totaled $392 thousand. We did not recognize any impairment losses on these low-income housing tax credit investments during the first six months of 2022 or 2021, as the value of the future tax benefits exceeds the carrying value of the investments.
Note 5: Loans and Allowance for Credit Losses on Loans
The following table presents the amortized cost of loans by class as of June 30, 2022 and December 31, 2021.

1 Amortized cost includes net deferred loan origination costs (fees) of $1.4 million and $(901) thousand at June 30, 2022 and December 31, 2021, respectively. Amounts are also net of unrecognized purchase discounts of $2.7 million and $2.5 million at June 30, 2022 and December 31, 2021, respectively. Amortized cost excludes accrued interest, which totaled $5.8 million and $7.1 million at June 30, 2022 and December 31, 2021, respectively, and is included in interest receivable and other assets in the consolidated statements of condition.
Lending Risks
Commercial and Industrial Loans - Commercial loans are generally made to established small and mid-sized businesses to provide financing for their growth and working capital needs, equipment purchases and acquisitions. Management examines historical, current, and projected cash flows to determine the ability of the borrower to repay obligations as agreed. Commercial loans are made based primarily on the identified cash flows of the borrower and secondarily on the underlying collateral and guarantor support. The cash flows of borrowers,
Page-16

however, may not occur as expected, and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed, such as accounts receivable and inventory, and typically include personal guarantees. We target stable businesses with guarantors who provide additional sources of repayment and have proven to be resilient in periods of economic stress. A weakened economy, and resultant decreased consumer and/or business spending, may have an effect on the credit quality of commercial loans.
Pursuant to the 2020 CARES Act, Bank of Marin originated 2,876 guaranteed loans totaling $444.1 million in two rounds of the Small Business Administration's ("SBA") Paycheck Protection Program ("PPP"). Additionally in 2021, Bank of Marin assumed 113 PPP loans totaling $18.6 million from ARB as of the merger date. As of June 30, 2022, there were 112 PPP loans outstanding totaling $17.0 million (net of $420 thousand in unrecognized fees and costs), compared to 368 loans outstanding at December 31, 2021 totaling $111.2 million (net of $2.5 million in unrecognized fees and costs) included in commercial and industrial loan balances. PPP loans have terms of two to five years and earn interest at 1%. In addition, the SBA paid the Bank a fee of 1%-5% depending on the loan amount, which was netted with loan origination costs and accreted/amortized into interest income using the effective yield method over the contractual life of each loan. The recognition of fees and costs is accelerated when the SBA forgives the loan and/or the loan is paid off prior to maturity. PPP loans are fully guaranteed by the SBA if they meet the requirements of the program. As expected, the vast majority of the PPP loans have been fully forgiven by the SBA and we expect the majority of remaining loans to be forgiven as well.
Commercial Real Estate Loans - Commercial real estate loans, which include income producing investment properties and owner-occupied real estate used for business purposes, are subject to underwriting standards and processes similar to commercial loans discussed above. We underwrite these loans to be repaid from cash flow from either the business or investment property and supported by real property collateral. Underwriting standards for commercial real estate loans include, but are not limited to, debt coverage and loan-to-value ratios. Furthermore, a large majority of our loans are guaranteed by the owners of the properties. Conditions in the real estate markets or downturn in the general economy may adversely affect our commercial real estate loans. In the event of a vacancy, we expect guarantors to carry the loans until they find a replacement tenant. The owner's substantial equity investment provides a strong economic incentive to continue to support the commercial real estate projects. As such, we have generally experienced a relatively low level of loss and delinquencies in this portfolio.
Construction Loans - Construction loans are generally made to developers and builders to finance construction, renovation and occasionally land acquisitions in anticipation of near-term development. Construction loans include interest reserves that are used for the payment of interest during the development and marketing periods and are capitalized as part of the loan balance. When a construction loan is placed on nonaccrual status before the depletion of the interest reserve, we apply the interest funded by the interest reserve against the loan's principal balance. These loans are underwritten after evaluation of the borrower's financial strength, reputation, prior track record, and independent appraisals. We monitor all construction projects to determine whether they are on schedule, completed as planned and in accordance with the approved construction budgets. Significant events can affect the construction industry, including: the inherent volatility of real estate markets and vulnerability to delays due to weather, change orders, inability to obtain construction permits, labor or material shortages, and price changes. Estimates of construction costs and value associated with the completed project may be inaccurate. Repayment of construction loans is largely dependent on the ultimate success of the project.
Consumer Loans - Consumer loans primarily consist of home equity lines of credit, other residential loans, floating homes, and indirect luxury auto loans, along with a small number of installment loans. Our other residential loans include tenancy-in-common fractional interest loans ("TIC") located almost entirely in San Francisco County. We originate consumer loans utilizing credit score information, debt-to-income ratio and loan-to-value ratio analysis. Diversification among consumer loan types, coupled with relatively small loan amounts that are spread across many individual borrowers, mitigates risk. We do not originate sub-prime residential mortgage loans, nor is it our practice to underwrite loans commonly referred to as "Alt-A mortgages," the characteristics of which are reduced documentation, borrowers with low FICO scores or collateral with high loan-to-value ratios.
Credit Quality Indicators
We use a risk rating system to evaluate asset quality, and to identify and monitor credit risk in individual loans, and in the loan portfolio. Our definitions of “Special Mention” risk graded loans, or worse, are consistent with those used by the Federal Deposit Insurance Corporation ("FDIC"). Our internally assigned grades are as follows:
Page-17

Pass and Watch - Loans to borrowers of acceptable or better credit quality. Borrowers in this category demonstrate fundamentally sound financial positions, repayment capacity, credit history and management expertise. Loans in this category must have an identifiable and stable source of repayment and meet the Bank’s policy regarding debt-service-coverage ratios. These borrowers are capable of sustaining normal economic, market or operational setbacks without significant financial consequences. Negative external industry factors are generally not present. The loan may be secured, unsecured or supported by non-real estate collateral for which the value is more difficult to determine and/or marketability is more uncertain. This category also includes “Watch” loans, where the primary source of repayment has been delayed. “Watch” is intended to be a transitional grade, with either an upgrade or downgrade within a reasonable period.
Special Mention - Potential weaknesses that deserve close attention. If left uncorrected, those potential weaknesses may result in deterioration of the payment prospects for the asset. Special Mention assets do not present sufficient risk to warrant adverse classification.
Substandard - Inadequately protected by either the current sound worth and paying capacity of the obligor or the collateral pledged, if any. A Substandard asset has a well-defined weakness or weaknesses that jeopardize(s) the liquidation of the debt. Substandard assets are characterized by the distinct possibility that we will sustain some loss if such weaknesses or deficiencies are not corrected. Well-defined weaknesses include adverse trends or developments of the borrower’s financial condition, managerial weaknesses and/or significant collateral deficiencies.
Doubtful - Critical weaknesses that make collection or liquidation in full improbable. There may be specific pending events that work to strengthen the asset; however, the amount or timing of the loss may not be determinable. Pending events generally occur within one year of the asset being classified as Doubtful. Examples include: merger, acquisition, or liquidation; capital injection; guarantee; perfecting liens on additional collateral; and refinancing. Such loans are placed on non-accrual status and usually are collateral-dependent.
We regularly review our credits for accuracy of risk grades whenever we receive new information. Borrowers are generally required to submit financial information at regular intervals. Typically, commercial borrowers with lines of credit are required to submit financial information with reporting intervals ranging from monthly to annually depending on credit size, risk and complexity. In addition, investor commercial real estate borrowers with loans exceeding a certain dollar threshold are usually required to submit rent rolls or property income statements annually. We monitor construction loans monthly. We review home equity and other consumer loans based on delinquency. We also review loans graded “Watch” or worse, regardless of loan type, no less than quarterly.
The following tables present the loan portfolio by loan class, origination year and internal risk rating as of June 30, 2022 and December 31, 2021. We early adopted the vintage disclosure requirements of ASU 2022-02 prospectively as described in Note 2 beginning with the first quarter of 2022. Accordingly, the 2022 vintage table reflects gross charge-offs by loan class and year of origination. Generally, existing term loans that were re-underwritten are reflected in the table in the year of renewal. Lines of credit that have a conversion feature at the time of origination, such as construction to perm loans, are presented by year of origination.

1 There were no non-performing loans past due more than ninety days and accruing interest as of June 30, 2022 and December 31, 2021.
2 None of the non-accrual loans as of June 30, 2022 or December 31, 2021 were earning interest on a cash basis. We recognized no interest income on non-accrual loans for the three and six months ended June 30, 2022 and 2021. There were three loans totaling $397 thousand placed on non-accrual status during the six months ended June 30, 2022 for which we reversed $8 thousand in interest income at the time of change in status, one of which for $16 thousand was subsequently charged off in the second quarter.
Collateral Dependent Loans
The following table presents the amortized cost basis of individually analyzed collateral-dependent loans, which are all on non-accrual status, by class at June 30, 2022 and December 31, 2021.

1 There were no collateral-dependent residential real estate mortgage loans in process of foreclosure or in substance repossessed at June 30, 2022 or December 31, 2021. The weighted average loan-to-value of collateral dependent loans was approximately 67% at both June 30, 2022 and December 31, 2021.
Troubled Debt Restructuring
Our loan portfolio includes certain loans modified in a troubled debt restructuring (“TDR”), where we have granted economic concessions to borrowers experiencing financial difficulties. These concessions typically result from our loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. TDRs on non-accrual status at the time of restructure may be returned to accruing status after management considers the borrower’s sustained repayment performance for a reasonable period, generally nine months, and obtains reasonable assurance of repayment and performance.
We may remove a loan from TDR designation if it meets all of the following conditions:
•The loan is subsequently refinanced or restructured at current market interest rates and the new terms are consistent with the treatment of creditworthy borrowers under regular underwriting standards;
Page-20

•The borrower is no longer considered to be in financial difficulty;
•Performance on the loan is reasonably assured; and
•Existing loan did not have any forgiveness of principal or interest.
There were no loans removed from TDR designation during the six months ended June 30, 2022 and 2021.
In accordance with section 4013 of the CARES Act, subsequently amended by section 541 of the 2020 Economic Aid Act, we elected to apply the temporary accounting relief provisions for loan modifications that met certain criteria, which would otherwise be designated as TDRs under existing GAAP. As of June 30, 2022, two borrowing relationships with three loans totaling $23.6 million were continuing to benefit from payment relief. The weighted average loan-to-value ratio of the remaining payment relief loans was approximately 44%. We accrue and recognize interest income on loans under payment relief based on the original contractual interest rates. When payments resume at the end of the relief period, the payments will generally be applied to accrued interest due until accrued interest is fully paid. We will continue to work closely with both of these clients and monitor their performance.
The following table summarizes the amortized cost of TDR loans by loan class as of June 30, 2022 and December 31, 2021.

Home equity | 479 |  | 386 |
Installment and other consumer | 571 |  | 607 |
Total 1 | $ | 9,539 |  | $ | 9,510 |

1 TDR loans on non-accrual status totaled $7.4 million at both June 30, 2022 and December 31, 2021. Unfunded commitments for TDR loans totaled $241 thousand and $441 thousand as of June 30, 2022 and December 31, 2021, respectively.

There was one loan modified in a TDR during the three and six months ended June 30, 2022 with a pre- and post-modification and end of period amortized cost of $100 thousand, and no loans modified in a TDR during the three and six months ended June 30, 2021. The modification in the second quarter of 2022 included a maturity date extension and interest rate concession. During the three and six months ended June 30, 2022 and 2021, there were no defaults on loans that had been modified in a TDR within the prior twelve-month period. We report defaulted TDRs based on a payment default definition of more than ninety days past due.

Pledged Loans
Our FHLB line of credit is secured under terms of a blanket collateral agreement by a pledge of certain qualifying loans with unpaid principal balances of $1.293 billion and $1.330 billion at June 30, 2022 and December 31, 2021, respectively. In addition, we pledge eligible TIC loans, which totaled $102.6 million and $106.2 million at June 30, 2022 and December 31, 2021, respectively, to secure our borrowing capacity with the Federal Reserve Bank ("FRB"). For additional information, see Note 6, Borrowings.
Related Party Loans
The Bank has, and expects to have in the future, banking transactions in the ordinary course of its business with directors, officers, principal shareholders and their businesses or associates. These transactions, including loans, are granted on substantially the same terms, including interest rates and collateral on loans, as those prevailing at the same time for comparable transactions with persons not related to us. Likewise, these transactions do not involve more than the normal risk of collectability or present other unfavorable features. Related party loans totaled $6.6 million at June 30, 2022 and $7.9 million at December 31, 2021. In addition, undisbursed commitments to related parties totaled $562 thousand at June 30, 2022 and $8.6 million at December 31, 2021. The decreases in both the outstanding amount and undisbursed commitment as of June 30, 2022 were primarily due to a Director retirement in the first quarter.
Note 6: Borrowings and Other Obligations
Federal Funds Purchased – The Bank had unsecured available lines of credit with correspondent banks for overnight borrowings totaling $150.0 million at June 30, 2022 and December 31, 2021. In general, interest rates on these lines approximate the federal funds target rate. We had no overnight borrowings under these credit facilities at June 30, 2022 or December 31, 2021.
Federal Home Loan Bank Borrowings – As of June 30, 2022 and December 31, 2021, the Bank had available lines of credit with the FHLB totaling $762.6 million and $820.5 million, respectively, based on eligible collateral of certain loans. There were no FHLB overnight borrowings at June 30, 2022 or December 31, 2021.
Federal Reserve Line of Credit – The Bank has an available line of credit with the Federal Reserve Bank of San Francisco ("FRBSF") secured by certain residential loans. At June 30, 2022 and December 31, 2021, the Bank had borrowing capacity under this line totaling $57.3 million and $70.8 million, respectively, and had no outstanding borrowings with the FRBSF.
Subordinated Debenture – As part of an acquisition in 2013, Bancorp assumed a subordinated debenture with a contractual balance of $4.1 million due to NorCal Community Bancorp Trust II (the "Trust"), established for the sole purpose of issuing trust preferred securities. On March 15, 2021, Bancorp redeemed in full the $2.8 million (book value) subordinated debenture due to the Trust, which had a 251.5% effective rate for the first six months of 2021, and included accelerated accretion of the $1.3 million remaining purchase discount due to the early redemption.
Page-22

Other Obligations – Finance lease liabilities totaling $356 thousand and $419 thousand at June 30, 2022 and December 31, 2021, respectively, are included in borrowings and other obligations in the consolidated statements of condition. See Note 8, Commitments and Contingencies, for additional information.
Note 7: Stockholders' Equity
Dividends
On July 22, 2022, Bancorp declared a $0.25 per share cash dividend, payable on August 12, 2022 to shareholders of record at the close of business on August 5, 2022.
Share-Based Payments
The fair value of stock options as of the grant date is recorded as stock-based compensation expense in the consolidated statements of comprehensive income over the requisite service period, which is generally the vesting period, with a corresponding increase in common stock. Stock-based compensation also includes compensation expense related to the issuance of restricted stock awards. The grant-date fair value of the restricted stock awards, which equals the grant date price, is recorded as compensation expense over the requisite service period with a corresponding increase in common stock as the shares vest. Beginning in 2018, stock option and restricted stock awards issued include a retirement eligibility clause whereby the requisite service period is satisfied at the retirement eligibility date. For those awards, we accelerate the recording of stock-based compensation when the award holder is eligible to retire. However, retirement eligibility does not affect the vesting of restricted stock or the exercisability of the stock options, which are based on the scheduled vesting period.
Performance-based stock awards (restricted stock) are issued to a selected group of employees. Stock award vesting is contingent upon the achievement of pre-established long-term performance goals set by the Compensation Committee of the Board of Directors. Performance is measured over a three-year period and cliff vested. These performance-based stock awards were granted at a maximum opportunity level, and based on the achievement of the pre-established goals, the actual payouts can range from 0% to 200% of the target award. For performance-based stock awards, an estimate is made of the number of shares expected to vest based on the probability that the performance criteria will be achieved to determine the amount of compensation expense to be recognized. The estimate is re-evaluated quarterly and total compensation expense is adjusted for any change in the current period.
We record excess tax benefits (deficiencies) resulting from the exercise of non-qualified stock options, the disqualifying disposition of incentive stock options and vesting of restricted stock awards as income tax benefits (expense) in the consolidated statements of comprehensive income with a corresponding decrease (increase) to current taxes payable.
The holders of unvested restricted stock awards are entitled to dividends on the same per-share ratio as holders of common stock. Tax benefits for dividends paid on unvested restricted stock awards are recorded as tax benefits in the consolidated statements of comprehensive income with a corresponding decrease to current taxes payable. Dividends on forfeited awards are included in stock-based compensation expense.
Stock options and restricted stock may be net settled in a cashless exercise by a reduction in the number of shares otherwise deliverable upon exercise or vesting in satisfaction of the exercise payment and/or applicable tax withholding requirements. During the six months ended June 30, 2022, we withheld 10,208 shares totaling $351 thousand at a weighted-average price of $34.38 for cashless exercises. During the six months ended June 30, 2021, we withheld 27,547 shares totaling $1.1 million at a weighted-average price of $38.87 for cashless exercises. Shares withheld under net settlement arrangements are available for future grants.
Share Repurchase Program
Bancorp has an approved share repurchase program with $34.7 million outstanding. The last activity under the program was in the first quarter of 2022. Bancorp repurchased 23,275 shares totaling $877 thousand in the first half of 2022. Cumulative shares repurchased under the current program totaled 618,991 shares as of June 30, 2022 at an average price of $36.04 per share. Bancorp continues to evaluate the resumption of share repurchases in the context of other capital and strategic initiatives.

Note 8: Commitments and Contingent Liabilities
Financial Instruments with Off-Balance Sheet Risk
We make commitments to extend credit in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit in the form of loans or through standby letters of credit. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Because various commitments will expire without being fully drawn, the total commitment amount does not necessarily represent future cash requirements.
Our credit loss exposure is equal to the contractual amount of the commitment in the event of nonperformance by the borrower. We use the same credit underwriting criteria for all credit exposure. The amount of collateral obtained, if deemed necessary by us, is based on management's credit evaluation of the borrower. Collateral types pledged may include accounts receivable, inventory, other personal property and real property.
The contractual amount of unfunded loan commitments and standby letters of credit not reflected in the consolidated statements of condition are as follows:

(in thousands) | June 30, 2022 | December 31, 2021
Commercial lines of credit | $ | 318,400 |  | $ | 330,234 |
Revolving home equity lines | 212,208 |  | 210,938 |
Undisbursed construction loans | 48,671 |  | 78,381 |
Personal and other lines of credit | 11,044 |  | 11,001 |
Standby letters of credit | 2,150 |  | 3,657 |
Total commitments and standby letters of credit | $ | 592,473 |  | $ | 634,211 |

We record an allowance for credit losses on unfunded loan commitments at the balance sheet date based on estimates of the probability that these commitments will be drawn upon according to historical utilization experience of the different types of commitments and expected loss rates determined for pooled funded loans. The allowance for credit losses on unfunded commitments totaled $1.5 million and $1.8 million as of June 30, 2022 and December 31, 2021, respectively, which is included in interest payable and other liabilities in the consolidated statements of condition. There was no adjustment to the allowance for credit losses on unfunded commitments for the second quarter of 2022, compared to a reversal of $612 thousand for the second quarter of 2021. This compares to year-to-date reversals of $318 thousand and $1.2 million in the six months ended June 30, 2022 and 2021 respectively, due to improved economic forecasts at the time.
Leases
We lease premises under long-term non-cancelable operating leases with remaining terms of 5 months to 10 years, most of which include escalation clauses and one or more options to extend the lease term, and some of which contain lease termination clauses. Lease terms may include certain renewal options that were considered reasonably certain to be exercised.
We lease certain equipment under finance leases with initial terms of 3 years to 5 years. The equipment finance leases do not contain renewal options, bargain purchase options or residual value guarantees.

The following table shows the future minimum lease payments, weighted average remaining lease terms, and weighted average discount rates under operating and finance lease arrangements as of June 30, 2022. Total minimum lease payments do not include obligations of approximately $1.7 million for an operating lease agreement related to a retail branch location that is expected to commence in the third quarter of 2022. The discount rates used to calculate the present value of lease liabilities were based on the collateralized FHLB borrowing rates that were commensurate with lease terms and minimum payments on the later of the date we adopted the new lease accounting standards or lease commencement date.

Litigation Matters
Bancorp may be party to legal actions that arise from time to time in the normal course of business. Bancorp's management is not aware of any pending legal proceedings to which either it or the Bank may be a party or has recently been a party that will have a material adverse effect on the financial condition or results of operations of Bancorp or the Bank.
The Bank is responsible for a proportionate share of certain litigation indemnifications provided to Visa U.S.A. ("Visa") by its member banks in connection with Visa's lawsuits related to anti-trust charges and interchange fees ("Covered Litigation"). Our proportionate share of the litigation indemnification liability does not change or transfer upon the sale of our Class B Visa shares to member banks. Visa established an escrow account to pay for settlements or judgments in the Covered Litigation. Under the terms of the U.S. retrospective responsibility plan, when Visa funds the litigation escrow account, it triggers a conversion rate reduction of the Class B common stock to shares of Class A common stock, effectively reducing the aggregate value of the Class B common stock held by Visa's member banks like us.
In 2012, Visa reached a $4.0 billion interchange multidistrict litigation class settlement agreement with plaintiffs representing a class of U.S. retailers. During the three months ended June 30, 2022, Visa deposited an additional $600 million into the litigation escrow account to address claims of certain merchants who opted out of the Amended Settlement Agreement for a balance of $1.5 billion. Combined with funds previously deposited with the court, these funds are expected to cover the settlement payment obligations.
The outcome of the Covered Litigation affects the conversion rate of Visa Class B common stock held by us to Visa Class A common stock, as discussed above and in Note 4, Investment Securities. The final conversion rate is subject to change depending on the final settlement payments, and the full effect on member banks is still uncertain. Litigation is ongoing and until the court approval process is complete, there is no assurance that Visa will resolve the claims as contemplated by the amended class settlement agreement, and additional lawsuits may arise from individual merchants who opted out of the class settlement. However, until the escrow account is fully depleted and the conversion rate of Class B to Class A common stock is reduced to zero, no future cash settlement payments are required by the member banks, such as us, on the Covered Litigation. Therefore, we are not required to record any contingent liabilities for the indemnification related to the Covered Litigation, as we consider the probability of losses to be remote.
Note 9: Derivative Financial Instruments and Hedging Activities
We entered into interest rate swap agreements, primarily as an asset/liability management strategy, in order to mitigate the changes in the fair value of specified long-term fixed-rate loans (or firm commitments to enter into long-term fixed-rate loans) caused by changes in interest rates. These hedges allow us to offer long-term fixed-rate loans to customers without assuming the interest rate risk of a long-term asset. Converting our fixed-rate interest payments to floating-rate interest payments, generally benchmarked to the one-month U.S. dollar LIBOR index, protects us against changes in the fair value of our loans associated with fluctuating interest rates.
Our credit exposure, if any, on interest rate swap asset positions is limited to the fair value (net of any collateral pledged to us) and interest payments of all swaps by each counterparty. Conversely, when an interest rate swap is in a liability position exceeding a certain threshold, we may be required to post collateral to the counterparty in an amount determined by the agreements. Collateral levels are monitored and adjusted on a regular basis for changes in interest rate swap values.
As of June 30, 2022, we had four interest rate swap agreements, which are scheduled to mature in June 2031, October 2031, July 2032, and October 2037. All of our derivatives are accounted for as fair value hedges. The notional amounts of the interest rate contracts are equal to the notional amounts of the hedged loans. Our interest rate swap payments are settled monthly with counterparties. Accrued interest on the swaps totaled $5 thousand at June 30, 2022 and $11 thousand at December 31, 2021. Information on our derivatives follows:

Note 10: Merger
Bancorp completed its merger and acquired all assets and assumed all liabilities of American River Bankshares on August 6, 2021. The Merger expanded Bank of Marin's presence throughout the Greater Sacramento, Amador and Sonoma County Regions where ARB had ten branches. T he Merger added $297.8 million in investment securities, $419.4 million in loans and $790.0 million in deposits to Bank of Marin as of the merger date. Bancorp accounted for the Merger as a business combination under the acquisition method of accounting. The assets acquired and liabilities assumed, both tangible and intangible, were recorded at their fair values as of the merger date in accordance with ASC 805, Business Combinations.
AMRB shareholders received 0.575 shares of Bancorp's common stock for each share of AMRB common stock outstanding immediately prior to the Merger resulting in the issuance of 3,441,235 shares of Bancorp common stock. In addition, merger consideration included cash paid for outstanding stock options and cash paid in lieu of fractional shares, as summarized in the following table.

(in thousands) | Merger Consideration
Value of common stock consideration paid to shareholders (0.575 fixed exchange ratio, stock price $36.15) | $ | 124,401 |
Cash consideration for stock options | 63
Cash paid in lieu of fractional shares | 13
Total merger consideration | $ | 124,477 |

We recorded $42.6 million in goodwill, which represents the excess of the total merger consideration paid over the fair value of the assets acquired, net of the fair values of liabilities assumed. Goodwill mainly reflects expected value created through the combined operations of AMRB and Bancorp and is evaluated for impairment annually.
The core deposit intangible ("CDI") represents the estimated future benefits of acquired deposits and is recorded separately from the related deposits. We recorded a core deposit intangible asset of $3.9 million related to the ARB merger, of w hich $179 thousand and $363 thousand, respectively, were amort ized in the three and six month periods ended June 30, 2022. No amortization was recognized in the comparable periods of 2021. The CDI is amortized on an accelerated basis over an estimated ten-year life and is evaluated periodically for impairment. No impairment loss was recognized as of June 30, 2022.
Merger-related one time and conversion costs are recognized as incurred and continue until all systems have been converted and operational functions are fully integrated. Bancorp's merger-related costs reflected in the consolidated statements of comprehensive income are summarized in the following table.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Management's discussion of the financial condition and results of operations, which is unaudited, should be read in conjunction with the related consolidated financial statements in this Form 10-Q and with the audited consolidated financial statements and accompanying notes included in our 2021 Annual Report on Form 10-K. Average balances, including balances used in calculating certain financial ratios, are generally comprised of average daily balances.
In November 2020, the SEC issued Final Rule 33-10890, Management’s Discussion and Analysis, Selected Financial Data and Supplementary Financial Information, which modernized and simplified certain disclosure requirements of Regulation S-K. The update to Item 303 of Regulation S-K related to interim period disclosures beginning with the first quarter of 2022 allows registrants to compare the results of the most recently completed quarter to the results of either the immediately preceding quarter or the corresponding quarter of the preceding year. Management believes that comparing current quarter results to those of the immediately preceding quarter is more useful in identifying current business trends and provides a more meaningful comparison. Accordingly, we have compared the results for the three months ended June 30, 2022 and March 31, 2022 throughout the Management's Discussion and Analysis sections, where applicable.
Forward-Looking Statements
This discussion of financial results includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, (the "1933 Act") and Section 21E of the Securities Exchange Act of 1934, as amended, (the "1934 Act"). Those sections of the 1933 Act and 1934 Act provide a "safe harbor" for forward-looking statements to encourage companies to provide prospective information about their financial performance so long as they provide meaningful, cautionary statements identifying important factors that could cause actual results to differ significantly from projected results.
Our forward-looking statements include descriptions of plans or objectives of management for future operations, products or services, and forecasts of revenues, earnings or other measures of economic performance. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include the words "believe," "expect," "intend," "estimate" or words of similar meaning, or future or conditional verbs preceded by "will," "would," "should," "could" or "may."
Forward-looking statements are based on management's current expectations regarding economic, legislative, and regulatory issues that may impact Bancorp's earnings in future periods. Factors that could cause future results to vary materially from current management expectations include, but are not limited to, general economic conditions and the economic uncertainty in the United States and abroad, including economic or other disruptions to financial markets caused by acts of terrorism, war or other conflicts such as Russia's military action in Ukraine, impacts from inflation, supply change disruptions, changes in interest rates (including the actions taken by the Federal Reserve to control inflation), California's unemployment rate, deposit flows, real estate values, and expected future cash flows on loans and securities; costs or effects of acquisitions; competition; changes in accounting principles, policies or guidelines; changes in legislation or regulation; natural disasters (such as wildfires and earthquakes in our area); adverse weather conditions; interruptions of utility service in our markets for sustained periods; and other economic, competitive, governmental, regulatory and technological factors (including external fraud and cybersecurity threats) affecting our operations, pricing, products and services; and successful integration of acquisitions.
Important factors that could cause results or performance to materially differ from those expressed in our prior forward-looking statements are detailed in ITEM 1A, Risk Factors section of our 2021 Form 10-K as filed with the SEC, copies of which are available from us at no charge. Forward-looking statements speak only as of the date they are made. We do not undertake to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made or to reflect the occurrence of unanticipated events.

Critical Accounting Estimates
Critical accounting estimates are those estimates made in accordance with generally accepted accounting principles that involve a significant level of estimation and uncertainty and have had or are reasonably likely to have a material impact on our financial condition and results of operations. We consider accounting estimates to be critical to our financial results if (i) the accounting estimate requires management to make assumptions about matters that are highly uncertain, (ii) management could have applied different assumptions during the reported period, and (iii) changes in the accounting estimate are reasonably likely to occur in the future and could have a material impact on our financial statements. Our critical estimates include: Allowance for Credit Losses on Loans and Unfunded Commitments, Income Taxes, and Fair Value Measurements. For a detailed discussion, refer to the Critical Accounting Estimates section of our 2021 Form 10-K filed with the SEC on March 15, 2022.
Executive Summary
We generated record net income for the second quarter of 2022 totaled $11.1 million, compared to $10.5 million in the first quarter of 2022. Diluted earnings per share were $0.69 in the second quarter of 2022, compared to $0.66 in the immediately preceding quarter. Earnings for the first six months of 2022 totaled $21.5 million, compared to $18.2 million in the same period last year. Diluted earnings per share were $1.35 and $1.37 in the first six months of 2022 and 2021, respectively. All periods of earnings presented were impacted by the costs associated with our most recent acquisition, the details of which are discussed throughout this report. In particular, diluted earnings per share for the first half of 2022 would have increased by one cent per share over 2021 without those costs.
The following are highlights of our operating and financial performance for the periods presented:
•Return on assets of 1.03% and return on equity of 10.74% for the three months ended June 30, 2022, would have been 1.05% and 10.95%, respectively, without one-time and conversion costs related to the 2021 merger with American River Bankshares ("ARB"). That compares to 0.98% and 9.61% (GAAP) and 1.01% and 9.96% (non-GAAP), respectively, for the three months ended March 31, 2022. As shown in the reconciliation of GAAP to non-GAAP financial measures on page 35, merger-related costs reduced net income by $219 thousand, net of taxes, or $0.02 per share in the second quarter.
•The second quarter tax-equivalent net interest margin improved 9 basis points over the preceding quarter despite the 7 basis point drag of declining PPP loan fee recognition. Rising interest rates had a positive impact on the Bank's asset sensitive portfolio, as did the deployment of excess cash into securities and flat deposit costs.
•Deposits increased by $22.1 million to $3.831 billion at June 30, 2022, compared to $3.809 billion at December 31, 2021. Non-interest bearing deposits made up 53% of total deposits as of June 30, 2022 versus 50% as of December 31, 2021, representing one of the strongest deposit franchises among peers. The cost of average deposits in the second quarter of 2022 was 0.06%, unchanged from the preceding quarter. The cost of average deposits in the first half of 2022 was 0.06%, a decrease from 0.07% in the first half of prior year.
•Loan balances of $2.163 billion at June 30, 2022 reflected record second quarter originations of $102.2 million and first half of the year originations of $152.0 million. While our production was strong and more than double the first half of 2021, total loans decreased modestly from December 31, 2021 balances driven by payoffs including expected construction project completions, borrowers' sales of underlying real estate and business assets, PPP loan payoffs, and third-party refinancing of acquired loans outside the Bank's credit risk appetite.
•Credit quality remains strong, with non-accrual loans representing 0.37% of total loans as of June 30, 2022, and December 31, 2021. There was not a significant change in classified loans. There was no provision made to the allowance for credit losses on loans or to the allowance for credit losses on unfunded loan commitments this quarter as an improvement in the California unemployment rate forecast decreased the quantitative portion of estimated credit losses while ongoing supply chain issues, inflation and recession risks increased qualitative factors. The preceding quarter's provision reversals were due primarily to the improved economic forecast at the time.
Page-30

•Our declining efficiency ratios quarter-over-quarter and year-over-year are a testament to the improved operating leverage attained through the ARB acquisition. The efficiency ratios of 55.73% for the second quarter and 57.40% year-to-date compare to 59.13% and 61.43% for the first quarter of 2022 and year to date 2021, respectively. Changes from the prior quarter were primarily visible in salaries, benefits and professional services expenses.
•All capital ratios were above well-capitalized regulatory requirements. The total risk-based capital ratio for Bancorp was 14.7% at June 30, 2022, compared to 14.6% at December 31, 2021. Bancorp's tangible common equity to tangible assets was 7.8% at June 30, 2022, compared to 8.8% at December 31, 2021 (refer to footnot e 4 on page 36 for a discussion of this non-GAAP financial measure). The total risk-based capital ratio for the Bank was 14.2% at June 30, 2022, compared to 14.4% at December 31, 2021. The Bank's tangible common equity to tangible assets was 7.5% at June 30, 2022, compared to 8.6% at December 31, 2021. Declines in the Bank's and Bancorp's tangible common equity and book value per share were primarily related to an increase in after-tax unrealized losses on available-for-sale securities associated with interest rate increases during 2022.
•Given the strength and durability of the Bank's financial performance, the Board of Directors declared a cash dividend of $0.25 per share, an increase from $0.24 per share in the prior quarter, on July 22, 2022, which represents the 69 th consecutive quarterly dividend paid by Bancorp. The dividend is payable on August 12, 2022, to shareholders of record at the close of business on August 5, 2022.

Statement Regarding use of Non-GAAP Financial Measures
In this Form 10-Q, Bancorp's financial results are presented in accordance with GAAP and with reference to certain non-GAAP financial measures. Management believes that presentation of operating results using non-GAAP financial measures provides useful supplemental information to investors and facilitates the analysis of Bancorp's operating results and comparison of operating results across reporting periods. Management also uses non-GAAP financial measures to establish budgets and manage Bancorp's business. A reconciliation of the GAAP financial measures to comparable non-GAAP financial measures is presented below.

1 Tax-equivalent net interest margin is computed by dividing taxable equivalent net interest income, which is adjusted for taxable equivalent income on tax-exempt loans and securities based on Federal statutory rate of 21 percent, by total average interest-earning assets.
2 Calculated as dividends on common shares divided by basic net income per common share.
3 The allowance for credit losses on loans to total loans, excluding SBA-guaranteed PPP loans, is considered a meaningful non-GAAP financial measure, as it represents only those loans that were considered in the calculation of the allowance for credit losses on loans. SBA PPP loans at June 30, 2022 and December 31, 2021 totaled $17.0 million and $111.2 million, respectively.
4 Tangible common equity to tangible assets is considered to be a meaningful non-GAAP financial measure of capital adequacy and is useful for investors to assess Bancorp's ability to absorb potential losses. Tangible common equity of $331 million and $371 million at June 30, 2022 and December 31, 2021, respectively, includes common stock, retained earnings and unrealized gains (losses) on available-for sale securities, net of tax, less goodwill and intangible assets. Tangible assets exclude goodwill and intangible assets of $78.6 million and $79.4 million at June 30, 2022 and December 31, 2021, respectively.

Net Interest Income
Net interest income is the interest earned on loans, investment and other interest-earning assets minus the interest expense incurred on deposits and other interest-bearing liabilities. Net interest income is impacted by changes in general market interest rates and by changes in the composition of interest-earning assets and interest-bearing liabilities. Interest rate changes can create fluctuations in the net interest income and/or margin due to an imbalance in the timing of repricing and maturity of assets and liabilities. We manage interest rate risk exposure with the goal of minimizing the impact of interest rate volatility on net interest income. For more information, refer to Item 3. Quantitative and Qualitative Disclosure about Market Risk in this Form 10-Q.
Net interest margin is expressed as net interest income divided by average interest-earning assets. Net interest rate spread is the difference between the average rate earned on total interest-earning assets and the average rate incurred on total interest-bearing liabilities. Both of these measures are reported on a taxable-equivalent basis. Net interest margin is the higher of the two because it reflects interest income earned on assets funded with non-interest-bearing sources of funds, which include demand deposits and stockholders’ equity.

2 Yields on available-for-sale securities are calculated based on amortized cost balances rather than fair value, as changes in fair value are reflected as a component of stockholders' equity. Investment security interest is earned on 30/360 day basis monthly. |
3 Yields and interest income on tax-exempt securities and loans are presented on a taxable-equivalent basis using the Federal statutory rate of 21 percent in 2022 and 2021. |
4 Average balances on loans outstanding include non-performing loans. The amortized portion of net loan origination fees is included in interest income on loans, representing an adjustment to the yield. |
5 2021 interest on subordinated debenture included $1.3 million in accelerated discount accretion from the early redemption of our last subordinated debenture on March 15, 2021. |

Analysis of Changes in Net Interest Income
The following table presents the effects of changes in average balances (volume) or changes in average rates on tax-equivalent net interest income for the periods indicated. Volume variances are equal to the increase or decrease in average balances multiplied by prior period rates. Rate variances are equal to the increase or decrease in rates multiplied by prior period average balances. Mix variances are attributable to the change in yields or rates multiplied by the change in average balances, including one more day in the three months ended June 30, 2022 compared to March 31, 2022.

1 Yields and interest income on tax-exempt securities and loans are presented on a taxable-equivalent basis using the federal statutory rate of 21%.
2 Six months ended June 30, 2021 includes $1.3 million in accelerated discount accretion from the early redemption of our last subordinated debenture on March 15, 2021.

Second Quarter of 2022 Compared to the First Quarter of 2022
Net interest income totaled $31.2 million in the second quarter of 2022, compared to $29.9 million in the first quarter of 2022. The $1.3 million increase from the prior quarter was primarily attributable to higher average balances and yields on investment securities driving an increase of $1.6 million, quarter-over-quarter in investment interest income.
The tax-equivalent net interest margin was 3.05% in the second quarter of 2022, compared to 2.96% in the first quarter of 2022. The increase from the prior quarter was primarily due to continued deployment of cash into higher yielding investment securities and higher interest rates on non-PPP loans, partially offset by lower interest and fee income on PPP loans. Average yields on the investment portfolio increased from 1.69% in the first quarter of 2022 to 1.87% in the second quarter reflecting recent increases in market interest rates, and the average rate on gross loans increased 10 basis points, which excludes the impact of loan origination fees/costs and purchase discounts/premiums.
First Six Months of 2022 Compared to the First Six Months of 2021
Net interest income totaled $61.1 million for the six months ended June 30, 2022, compared to $46.6 million for the same period in the prior year. The $14.5 million increase from the prior year was primarily due to the larger investment portfolio generating an incremental $8.3 million, and $4.9 million related to higher balances and yields on the loan portfolio (net of a $3.7 million decrease in interest and fees on PPP loans). Additionally, 2021 included a $1.3 million accelerated discount from the early redemption of a subordinated debenture.
The tax-equivalent net interest margin was 3.01% in the six months ended June 30, 2022, compared to 3.28% in the same period in the prior year. The decrease was primarily attributed to a higher proportion of investment securities in the larger balance sheet associated with ARB's lower loan-to-deposit ratio and other deposit growth over the period. The decrease was partially offset by a shift to a higher percentage of non-PPP loans within the loan portfolio and the absence of trust preferred securities redemption that occurred in 2021.
Market Interest Rates
Market interest rates are, in part, based on the target federal funds interest rate (the interest rate banks charge each
other for short-term borrowings) implemented by the Federal Reserve Open Market Committee ("FOMC").
In response to economic risks posed by the COVID-19 pandemic, the FOMC made two emergency cuts totaling 150 basis points to the federal funds rate in March 2020. The federal funds target rate range resided between 0.0% a nd 0.25% after March 15, 2020 through the beginning of 2022, putting downward pressure on our asset yields and net interest margin through early 2022. I n its March 16, 2022 meeting, the FOMC raised the target federal funds by 25 basis points followed by a 50 basis point increase on May 4, 2022. C ontinued evolving economic risks exacerbated by global economic contraction and international political unrest, have resulted in shortages of oil, other supply
Page-36

chain disruptions, and elevated inflation. In response, the FOMC increased the federal funds rate by 75 basis points twice effective June 16, 2022 and July 28, 2022 to a range of 2.25% - 2.50%. It is widely anticipated that additional increases in the target range will occur in 2022. Our net interest margin should benefit from a rising interest rate environment. See ITEM 3. Quantitative and Qualitative Disclosure about Market Risk for further information.
Provision for Credit Losses on Loans
Management assesses the adequacy of the allowance for credit losses on loans quarterly based on several factors including growth of the loan portfolio, past events, current conditions, and reasonable and supportable forecasts to estimate expected losses over the contractual terms of our loans. The allowance for credit losses on loans is increased by provisions charged to expense and loss recoveries and decreased by loans charged off.
The following table shows the activity for the periods presented.

| Three months ended |  | Six months ended
(dollars in thousands) | June 30, 2022 | March 31, 2022 |  |  | June 30, 2022 | June 30, 2021
Reversal of credit losses on loans | $ | — |  | $ | (485) |  |  |  | $ | (485) |  | $ | (3,849) |

There was no provision made to the allowance for credit losses on loans in the second quarter. An improvement in the California unemployment rate forecast decreased the quantitative portion of estimated credit losses while ongoing supply chain issues, inflation and recession risks increased qualitative factors. The reversal of the allowance for credit losses on loans in the prior quarter primarily resulted from improved forecasted economic conditions at the time. The provision reversals in the six months ended June 30, 2021 were primarily due to improvements in the forecasted California unemployment rates at the time and decrease in non-PPP loan balances.
Loans designated special mention, which are not considered adversely classified, decreased year-to-date by $14.7 million to $58.6 million at June 30, 2022 from $73.3 million at December 31, 2021. The decrease was largely due to $22.3 million in upgrades to pass risk ratings because of the borrowers' improved financial condition, which was offset by $11.5 million in downgrades from pass to special mention. Additionally, there were $3.6 million in downgrades from special mention to substandard, and $908 thousand in paydowns and payoffs.
Classified assets (loans with risk ratings of substandard or doubtful) totaled $36.9 million at June 30, 2022, compared to $36.2 million at December 31, 2021. The $815 thousand increase was primarily related to $5.1 million in commercial loans to one borrowing relationship that were downgraded from special mention to substandard (comprised of $3.6 million as of December 31, 2021 and $1.5 million in additional advances in 2022) and the downgrade of two well-secured owner occupied commercial real estate loans totaling $2.3 million and two home equity loans totaling $128 thousand. Additionally, there were $5.2 million in upgrades to pass and $832 thousand in paydowns and payoffs. Classified loans also included one $106 thousand loan acquired from ARB with a doubtful risk rating as of June 30, 2022 and December 31, 2021, which is well-secured by real estate collateral.
The ratio of allowance for credit losses on loans to total loans was 1.04% and 1.02% at June 30, 2022 and December 31, 2021, respectively. Non-accrual loans decreased $358 thousand to $8.0 million, or 0.37% of total loans at June 30, 2022 from $8.4 million, or 0.37% of total loans at December 31, 2021.

Second Quarter of 2022 Compared to First Quarter of 2022
Non-interest income totaled $2.7 million in the second quarter of 2022, compared to $2.9 million in the preceding quarter. The $139.0 thousand decrease was primarily related to payments on bank-owned life insurance in the prior quarter.
First Six Months of 2022 Compared to the First Six Months of 2021
Non-interest income totaled $5.6 million in the six months ended June 30, 2022, compared to $3.8 million in the same period of the prior year. The $1.7 million improvement from the prior year period was evident in all categories and mostly attributable to increased activity associated with the ARB acquisition and higher Wealth Management and Trust Services income.

Second Quarter of 2022 Compared to First Quarter of 2022
Non-interest expense totaled $18.9 million in the second quarter of 2022, compared to $19.4 million in the prior quarter. The decrease from the prior quarter was primarily due to a $1.2 million reduction in salaries and benefits after the completion of the acquisition-related conversion in March 2022 and 22 fewer full-time equivalent employees. Decreases were partially offset by a $466 thousand increase in charitable contributions in the quarter due to the annual distribution of grant funding related to the Bank's corporate giving program.
First Six Months of 2022 Compared to the First Six Months of 2021
Non-interest expense totaled $38.3 million in the six months ended June 30, 2022, compared to $31.0 million in the same period of prior year. The largest increases over prior year expenses came from salaries and related benefits, which rose $3.8 million due to increased numbers of employees in acquired branch and loan offices, regularly scheduled annual merit and related increases, and lower deferred loan origination costs (the first six months of 2021 included PPP round two origination activity). Higher expenses across most other categories reflect the acquisition, including one-time and conversion costs of $858 thousand, an increase in other data processing of $762 thousand, and an additional $346 thousand in amortization associated with the ARB core deposit intangible asset in the first half of 2022.
Provision for Income Taxes
Income tax provisions reflect accruals for taxes at the applicable rates for federal income tax and California franchise tax based upon reported pre-tax income. Provisions also reflect permanent differences between income for tax and financial reporting purposes (such as earnings on tax exempt loans and municipal securities, BOLI, low-income housing tax credits, and stock-based compensation from the exercise of stock options, disqualifying dispositions of incentive stock options and vesting of restricted stock awards).
The provision for income taxes for the second quarter of 2022 totaled $4.0 million at an effective tax rate of 26.3%, compared to $3.7 million at an effective tax rate of 26.3% in the prior quarter. The provision for income taxes for the first half of 2022 totaled $7.7 million at an effective tax rate of 26.3%, compared to $6.3 million at an effective tax rate of 25.6% for the first half of 2021. The increase in the provision in the second quarter of 2022 reflected higher pre-tax income as compared to the prior quarter. The 70 basis point increase in the effective tax rate in the first half of 2022 as compared to the first half of 2021 was primarily due to a higher level of tax benefits in 2021 from the disqualifying dispositions of incentive stock options.
We file a consolidated return in the U.S. Federal tax jurisdiction and a combined return in the State of California tax jurisdiction. There were no ongoing federal or state income tax examinations at the issuance of this report. At June 30, 2022, neither the Bank nor Bancorp had accruals for interest nor penalties related to unrecognized tax benefits.

FINANCIAL CONDITION SUMMARY
Cash, Cash Equivalents and Restricted Cash
Total cash, cash equivalents and restricted cash were $115.9 million at June 30, 2022, compared to $347.6 million at December 31, 2021. The $231.7 million decrease was primarily due to the deployment of funds into investment securities, as noted below. Cash and cash equivalents do not include $152.4 million and $173.1 million in temporary one-way sale transfers of deposits to third-party deposit networks as part of our liquidity management at June 30, 2022 and December 31, 2021, respectively.
Investment Securities
The investment securities portfolio totaled $1.825 billion at June 30, 2022, an increase of $314.9 million from December 31, 2021. The increase was primarily due to purchases of $492.5 million to deploy excess cash into interest earning assets in a more favorable interest rate environment in 2022, partially offset by paydowns, maturities and calls of $93.1 million. Additionally, the unrealized losses on available-for-sale securities increased $80.1 million as a result of higher interest rates in the first six months of 2022. In March 2022, we transferred $357.5 million securities at fair value from available-for-sale to held-to-maturity to reduce the effect of future rate increases on the available-for-sale portfolio mark-to-market, other comprehensive income and equity. See Note 4, Investment Securities, for additional information.
The following table summarizes our investment in obligations of state and political subdivisions at June 30, 2022 and December 31, 2021.

Percent of investment portfolio | 10.2 | % | 9.8 | % |  |  | 11.7 | % | 12.0 | % |

Of the total investment in obligations of state and political subdivisions, the largest concentrations outside of California are in Texas (38.2%), Washington (15.0%) and Wisconsin (9.7%). Our investment in obligations issued by municipal issuers in Texas are either guaranteed by the AAA-rated Texas Permanent School Fund ("PSF") or backed by revenue sources from essential services (such as utilities and transportation). We have $6.0 million in obligations of Texas school district issuers having high concentrations in oil and gas industry taxpayers and all of them have credit guarantees from PSF.
Investments in states, municipalities and political subdivisions are subject to an initial pre-purchase credit assessment and ongoing monitoring. Key considerations include:
•The soundness of a municipality’s budgetary position and stability of its tax revenues
•Debt profile and level of unfunded liabilities, diversity of revenue sources, taxing authority of the issuer
•Local demographics/economics including unemployment data, largest taxpayers and local employers, income indices and home values
•For revenue bonds, the source and strength of revenue for municipal authorities including the obligor’s financial condition and reserve levels, annual debt service and debt coverage ratio, and credit enhancement (such as insurer’s strength and collateral in escrow accounts)
•Credit ratings by major credit rating agencies

Loans
During the first six months of 2022, loans decreased by $93.0 million and totaled $2.163 billion at June 30, 2022, primarily due to $94.2 million in PPP loans being forgiven and paid off. New non-PPP related loan originations totaled $152.0 million in the first six months of 2022. Non-PPP loan payoffs were $159.1 million in the first six months of 2022, including construction project completions of $34.6 million. These payoffs also reflected borrowers' sales of underlying real estate and business assets and third-party refinancing of acquired loans outside the Bank's credit risk appetite.
As of June 30, 2022, there were 112 PPP loans outstanding totaling $17.0 million (net of $420 thousand in unrecognized fees and costs) compared to 368 loans outstanding December 31, 2021 for a total of $111.2 million (net of $2.5 million in unrecognized fees and costs). In the first half of 2022, Bank of Marin recognized $2.1 million in PPP fees, net of costs, compared to $4.3 million in the same period of 2021.
As of June 30, 2022, two borrowing relationships with three loans totaling $23.6 million were continuing to benefit from payment relief under the provisions of the 2020 CARES Act. We will continue to work closely with both of these clients and monitor their performance.
Liabilities
During the first six months of 2022, total liabilities increased by $53.5 million to $3.917 billion. Deposits increased $22.1 million in the first six months of 2022 to $3.831 billion. Non-interest bearing deposits increased $124.5 million while money market deposits decreased $103.5 million in the first six months of 2022, and was partially related to a large transfer to non-interest bearing deposits by a significant customer in preparation for withdrawals in early July consistent with that customer's normal business activity. Non-interest bearing deposits represented 53.1% of total deposits at June 30, 2022, compared to 50.2% at December 31, 2021. The average cost of deposits was 0.06% in the first half of 2022 compared to 0.07% in the same period of 2021. Additionally, as part of our liquidity management, the Bank maintained $152.4 million in deposits off-balance sheet with deposit networks at June 30, 2022, compared to $173.1 million at December 31, 2021.
Capital Adequacy
We are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements as set forth in the following tables can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a material effect on our consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and the Bank’s prompt corrective action classification are also subject to qualitative judgments by the regulators about components of capital, risk weightings and other factors.
Management reviews capital ratios on a regular basis and produces a five-year capital plan semi-annually to ensure that capital exceeds the prescribed regulatory minimums and is adequate to meet our anticipated future needs. Stress tests are performed on capital ratios and include scenarios such as additional unrealized losses on the investment portfolio, additional deposit growth and potential share repurchases. For all periods presented, the Bank’s ratios exceed the regulatory definition of “well capitalized” under the regulatory framework for prompt corrective action and Bancorp’s ratios exceed the required minimum ratios to be considered a well-capitalized bank holding company. In addition, the most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action as of June 30, 2022. There are no conditions or events since that notification that management believes have changed the Bank’s categories and we expect the Bank to remain well capitalized for prompt corrective action purposes.

Liquidity and Capital Resources
The goal of liquidity management is to provide adequate funds to meet loan demand and to fund operating activities and deposit withdrawals. We accomplish this goal by maintaining an appropriate level of liquid assets and formal lines of credit with the FHLB, FRBSF and correspondent banks that enable us to borrow funds as discussed in Note 6 to the Consolidated Financial Statements in ITEM 1 of this report. Our Asset Liability Management Committee ("ALCO"), which is comprised of independent Bank directors and the Bank's Chief Executive Officer, is responsible for approving and monitoring our liquidity targets and strategies, which are subject to projection and stress testing over a two-year horizon. ALCO has adopted a contingency funding plan that provides early detection of potential liquidity issues in the market or the Bank and institutes prompt responses that may prevent or alleviate a potential liquidity crisis. Management monitors liquidity daily and regularly adjusts our position based on current and future liquidity needs. We also have relationships with third-party deposit networks and can adjust the placement of our deposits via reciprocal or one-way sales as part of our cash management strategy. We maintained $152.4 million in one-way-sale deposits off-balance sheet with deposit networks at June 30, 2022, compared to $173.1 million at December 31, 2021.
We obtain funds from the repayment and maturity of loans, deposit inflows, investment security maturities and paydowns, federal funds purchases, FHLB advances, other borrowings, and cash flow from operations. Our primary uses of funds are the origination of loans, the purchase of investment securities, withdrawals of deposits, maturity of certificates of deposit, repayment of borrowings, and dividends to common stockholders.
T he most significant component of our daily liquidity position is customer deposits. The attraction and retention of new deposits depends upon the variety and effectiveness of our customer account products, service and
Page-42

convenience, rates paid to customers, and our financial strength. The cash cycles and unique business activities of some of our large commercial depositors may cause short-term fluctuations in their deposit balances held with us.
Our cash and cash equivalents decreased $231.7 million in the first six months of 2022. Significant uses of liquidity during 2022 were $452.2 million in investment securities purchased, $7.7 million in cash dividends paid on common stock to our shareholders, and $1.2 million in common stock repurchases. Refer to the Consolidated Statement of Cash Flows in this Form 10-Q for additional information on our sources and uses of liquidity. Management anticipates that our current strong liquidity position and core deposit base are adequate to fund our operations.
The most significant source of liquidity during the first six months of 2022 was proceeds from loans collected (net of loan originations) of $93.9 million, principal paydowns, maturities and calls of investment securities of $93.1 million, a net increase in deposits of $22.1 million (primarily related to $25 million of one-way sell deposits that was previously placed in third-party deposit networks being brought back on balance sheet), and $19.6 million in net cash provided by operating activities.
Undrawn credit commitments, as discussed in Note 8 to the Consolidated Financial Statements in this Form 10-Q, totaled $592.5 million at June 30, 2022. We expect to fund these commitments to the extent utilized primarily through the repayment of existing loans, deposit growth and liquid assets. Over the next twelve months, $107.5 million of time deposits will mature. We expect to replace these funds with new deposits or excess liquidity. Our emphasis on local deposits, combined with our liquid investment portfolio, provides a very stable funding base. While we had no borrowings under our credit facilities at June 30, 2022 or December 31, 2021, as discussed in Note 6 to the Consolidated Financial Statements in ITEM 1 of this report, the available credit lines with FHLB and FRB SF have declined by $71.4 million from December 30, 2021 to June 30, 2022, primarily because the rising market interest rates in the first half of 2022 have unfavorably affected the market value of the loans collateralizing these lines.
Since Bancorp is a holding company and does not conduct regular banking operations, its primary sources of liquidity are dividends from the Bank. Under the California Financial Code, payment of a dividend from the Bank to Bancorp without advance regulatory approval is restricted to the lesser of the Bank’s retained earnings or the amount of the Bank’s net profits from the previous three fiscal years less the amount of dividends paid during that period. The primary uses of funds for Bancorp are shareholder dividends and ordinary operating expenses. Bancorp held $13.0 million in cash at June 30, 2022, which is expected to be sufficient to cover Bancorp's operational needs and cash dividends to shareholders through 2022. Management anticipates that there will be sufficient earnings at the Bank to provide dividends to Bancorp to meet its funding requirements for the foreseeable future.
ITEM 3. Quantitative and Qualitative Disclosure about Market Risk
Market risk is defined as the risk of loss arising from an adverse change in the market value (or prices) of financial instruments. A significant component of market risk is interest rate risk, which is inherent in our lending, investment, borrowing and deposit gathering activities. The Bank manages interest rate sensitivity to minimize the exposure of our net interest margin, earnings, and capital to changes in interest rates. Interest rate changes can create fluctuations in the net interest margin due to an imbalance in the timing of repricing or maturity of assets or liabilities. Interest rate changes can also affect the market value of our financial instruments, such as available-for-sale securities and the related unrealized gains or losses, which affects our equity value.
To mitigate interest rate risk, the structure of our assets and liabilities is managed with the objective of correlating the effects of interest rate changes on loans and investments with those of deposits and borrowings. The asset liability management policy sets limits on the acceptable amount of change to net interest income and economic value of equity in different interest rate environments.
From time to time, we enter into interest rate swap contracts to mitigate the changes in the fair value of specified long-term fixed-rate loans and firm commitments to enter into long-term fixed-rate loans caused by changes in interest rates. See Note 9 to the Consolidated Financial Statements in this Form 10-Q.
ALCO and the Board of Directors review our exposure to interest rate risk at least quarterly. We use simulation models to measure interest rate risk and to evaluate strategies to improve profitability. A simplified statement of condition is prepared on a quarterly basis as a starting point, using instrument level data of our actual loans, investments, borrowings and deposits as inputs. If potential changes to net equity value and net interest income
Page-43

resulting from hypothetical interest rate changes are not within the limits established by the Board of Directors, management may adjust the asset and liability mix to bring the risk position within approved limits or take other actions. At June 30, 2022, interest rate risk was within policy guidelines established by ALCO and the Board. One set of interest rates modeled and evaluated against flat interest rates and a static balance sheet is a series of immediate parallel shifts in the yield curve. Our most recent analysis of our interest rate sensitivity is provided in the following table as an example rather than an expectation of likely interest rate movements.

Immediate and Parallel Shift in Interest Rates (in basis points) | Estimated Change in Net Interest Income in Year 1, as percent of Net Interest Income | Estimated Change in Net Interest Income in Year 2, as percent of Net Interest Income
up 400 | 6.9 | % | 16.3 | %
up 300 | 2.5 | % | 9.8 | %
up 200 | 1.8 | % | 6.8 | %
up 100 | 1.2 | % | 4.0 | %
down 100 | (4.6) | % | (8.1) | %

Asset sensitivity increased over the quarter primarily due to a reduction in our deposit betas, floating rate loans repricing above their respective floors and fully-indexed rates on adjustable loans in position to move above floors at next repricing. Interest rate sensitivity is a function of the repricing characteristics of our assets and liabilities. The Bank runs a combination of scenarios and sensitivities in its attempt to capture the range of interest rate risk including the simulations mentioned above. As with any simulation model or other method of measuring interest rate risk, limitations are inherent in the process and dependent on assumptions. For example, if we choose to pay interest on certain business deposits that are currently non-interest bearing, causing those deposits to become rate sensitive in the future, we would become less asset sensitive than the model currently indicates. Additionally, assets and liabilities may react differently to changes in market interest rates in terms of both timing and responsiveness to market rate movements. Important deposit modeling assumptions include the speed of deposit run-off and the amount by which interest-bearing deposit rates increase or decrease when market interest rates change, otherwise known as the deposit beta. We lowered the average interest-bearing deposit beta to 26% from last quarter's 58% in rising rate scenarios, which is much closer to historical levels for Bank of Marin. The actual rates and timing of prepayments on loans and investment securities could vary significantly from the assumptions applied in the various scenarios. Lastly, uneven changes in different tenors of U.S. Treasury rates that result in changes to the shape of the yield curve could produce different results from those presented in the table. Accordingly, the results presented should not be relied upon as indicative of actual results in the event of changing market interest rates.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Bank of Marin Bancorp and its subsidiary (the "Company") conducted an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934 (the “Act”)) as of the end of the period covered by this report. The term disclosure controls and procedures means controls and other procedures that are designed to ensure that information we are required to disclose in the reports that we file or submit under the Act (15 U.S.C. 78a et seq.) is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information we are required to disclose in the reports that we file or submit under the Act is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.
Changes in Internal Control over Financial Reporting
