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 2022 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 (loss), 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 Adopted in 2023
In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendment eliminated the recognition measurement guidance for troubled debt restructured ("TDR") loans and instead enhanced disclosure requirements for certain loan modifications when a borrower is experiencing financial difficulty. In addition, the amendment required that an entity include in its vintage disclosures the current period gross loan charge-offs by year of origination. We early adopted the current period charge-off disclosures in the first quarter of 2022. We adopted the loan modification provisions as
Page-7

of January 1, 2023 using a modified retrospective method. The cumulative-effect adjustment to retained earnings was considered immaterial. Refer to Note 5, Loans and Allowance for Credit Losses on Loans, for additional information.
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 renamed the "last-of-layer" method to the "portfolio layer" method and made 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. We adopted the amendments on January 1, 2023, which had no effect on our existing hedge accounting, disclosures, financial condition or results of operations.
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 reference rate reform. Topic 848 was further amended in January 2021 with ASU No. 2021-01, which provided additional guidance on certain optional expedients and scope of derivative instruments, and in December 2022 with ASU 2022-06, which extended the sunset date of Topic 848 to December 31, 2024 given the UK Financial Conduct Authority ("FCA") March 2021 announcement that the intended cessation date of certain tenors of USD LIBOR would be June 30, 2023. An entity may elect the amendments in these updates at an interim period with adoption methods varying based on transaction type. As of September 30, 2023, we had four interest rate swap contracts with notional values totaling $11.3 million that were indexed to LIBOR, which transitioned to the Secured Overnight Financing Rate ("SOFR") effective July 1, 2023. The transition to SOFR did not have a material impact to either our financial condition or results of operations.
Accounting Standards Not Yet Effective
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, on July 13, 2023 we sold our remaining shares of Visa Inc. Class B restricted common stock. As a result of the sale, this update will not impact our financial condition, results of operations or disclosures.
In March 2023, the FASB issued ASU No. 2023-01, Leases (Topic 842): Common Control Arrangements. For public companies, the amendment requires entities to amortize leasehold improvements associated with common control lease arrangements over the useful life of the improvements to the common control group, as opposed to the shorter of the remaining lease term and the useful life of the improvements for all other operating leases. The amendments are effective for years beginning after December 15, 2023, and may be adopted either prospectively or retrospectively. Early adoption is permitted for both interim and annual financial statements. We currently do not have common control lease arrangements, and therefore do not anticipate that the amendments will impact our financial condition and results of operations.
In March 2023, the FASB issued ASU No. 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. Under current GAAP, an entity can only elect to apply the proportional amortization method to investments in low-income housing tax credit ("LIHTC") structures. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the consolidated statements of income as a component of income tax expense (benefit). The amendments will allow entities to elect to account for all other equity investments made primarily for the purpose of receiving income tax credits to using the proportional amortization method, regardless of the tax credit program through which the investment earns income tax credits,
Page-8

when certain conditions are met. The amendments are effective for fiscal years beginning after December 15, 2023, and may be adopted either on a modified retrospective basis or retrospectively. Other than investments in LIHTC funds, as disclosed in Note 4, Investment Securities, we currently have no other equity investments made primarily for the purpose of receiving income tax credits, and therefore do not anticipate that the amendments will impact our financial condition and 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.

1 Other comprehensive income ("OCI") or net income ("NI").
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 September 30, 2023 and December 31, 2022, there were no Level 3 securities.
Held-to-maturity securities may be subject to an allowance for credit losses as a result of our evaluation of expected losses due to credit quality factors. We did not record any credit loss expense on held-to-maturity securities during the nine months ended September 30, 2023 or September 30, 2022. 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. These unobservable inputs are not considered significant inputs to the fair value measurement overall. Level 2 inputs for the valuations are limited to observable market prices for Secured Overnight Financing Rate ("SOFR") and Overnight Index Swap ("OIS") rates (for the very short term), quoted prices for SOFR futures contracts, observable market prices for SOFR and OIS swap rates, and one-month and three-month SOFR 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
Page-10

SOFR for the closest maturity term corresponding to the duration of the swaps to derive the CVA. Because there is little to no counterparty risk, we did not incorporate credit adjustments from our assessment of the counterparty credit risk in determining fair value. 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 is classified as Level 3 and 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. On July 12, 2023, the Bank completed the sale of its only OREO property.
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 September 30, 2023 and December 31, 2022.

Disclosures about Fair Value of Financial Instruments
The table below is a summary of fair value estimates for financial instruments as of September 30, 2023 and December 31, 2022, 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 at cost as of September 30, 2023 and December 31, 2022, and Visa Inc. Class B common stock with no carrying value, as of December 31, 2022, which was sold entirely in July of 2023. There were 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 September 30, 2023 or December 31, 2022. 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
Page-11

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.
Due to the short-term nature of the FHLB borrowings outstanding as of December 31, 2022, the carrying value approximated fair value.
The fair value of the borrowings under the BTFP is estimated by discounting the contractual cash flow using the program's period end financing rate.
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 September 30, 2023 or December 31, 2022.
Note 4: Investment Securities
Our investment securities portfolio consists of U.S. Treasury securities, obligations of state and political subdivisions, U.S. federal government agencies such as Government National Mortgage Association ("GNMA") and Small Business Administration ("SBA"), U.S. government-sponsored enterprises ("GSEs"), such as Federal National Mortgage Association ("FNMA"), Federal Home Loan Mortgage Corporation ("FHLMC"), Federal Farm Credit Banks Funding Corporation and FHLB and U.S. Corporations. We also invest in residential and commercial mortgage-backed securities (“MBS”/"CMBS") and collateralized mortgage obligations (“CMOs”) issued or guaranteed by the GSEs, as reflected in the following table.

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
Page-12

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 our comprehensive anal ysis, no cred it losses are expected.

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 and the related accumulated other comprehensive loss are accreted to interest income over the remaining lives of the securities. Because these entries offset each other, there was no impact to net income.

In October 2023, the Bank sold $55.0 million of available-for-sale securities for a pretax net loss of $2.1 million (or $1.5 million after tax). Management did not have the intent and was not required to sell these securities at the reporting date. Therefore, no impairment loss was recognized in the third quarter of 2023.

As of September 30, 2023, the investment portfolio included 323 investment securities that had been in a continuous loss position for twelve months or more and 8 investment securities that had been in a loss position for less than twelve months.
Securities issued by government-sponsored enterprises, 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.
No allowances for credit losses have been recognized on available-for-sale securities in an unrealized loss position, as management did not believe any of the securities were impaired due to credit risk factors at either September 30, 2023 or December 31, 2022. In addition, for any available-for-sale securities in an unrealized loss position at September 30, 2023 and December 31, 2022, the Bank assessed whether it intended to sell the securities, or if it was more likely than not that it would be required to sell the securities before recovery of its amortized cost basis, which would require a write-down to fair value through net income. Because the Bank did not intend to sell those securities that were in an unrealized loss position, and it was not more-likely-than-not that the Bank would be required to sell the securities before recovery of their amortized cost bases, the Bank determined that no write-down was necessary as of the reporting date.
On July 7, 2023, the Bank entered into various interest rate swap agreements with notional values totaling $101.8 million to hedge balance sheet interest rate sensitivity and protect selected securities in its available-for-sale
Page-16

portfolio against changes in fair value related to changes in the benchmark interest rate. For additional details, refer to Note 9, Derivative Financial Instruments and Hedging Activities.
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 September 30, 2023 and December 31, 2022. The carrying amounts of 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 w as not im paired at September 30, 2023 and December 31, 2022. On October 26, 2023, FHLB announced a cash dividend for the third quarter of 2023 at an annualized dividend rate of 8.25% to be distributed on Novembe r 9, 20 23. 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 December 31, 2022. These shares had a carrying value of zero and were 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 lacked a readily determinable fair value. On July 13, 2023, the Bank sold the entirety of its remaining investment in Visa Inc. Class B restricted common stock for a $2.8 million gain.
For further information on the Covered Litigation, 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 $2.1 million and $2.5 million recorded in other assets as of September 30, 2023 and December 31, 2022, respectively. In the first nine months of 2023, we recognized $450 thousand of low-income housing tax credits and other tax benefits, offset by $377 thousand of amortization expense of low-income housing tax credit investment, as a component of income tax expense. As of September 30, 2023, our unfunded commitments for these low-income housing tax credit funds totaled $346 thousand. We did not recognize any impairment losses on these low-income housing tax credit investments during the first nine months of 2023 or 2022, as the value of the future tax benefits exceeds the carrying value of the investments.

Amounts are also net of unrecognized purchase discounts of $2.2 million and $2.6 million at September 30, 2023 and December 31, 2022, respectively. Amortized cost excludes accrued interest, which totaled $6.3 million and $6.1 million at September 30, 2023 and December 31, 2022, 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, 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.
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:
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
Page-18

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 and at each quarterly and year-end reporting period. 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 portfolio class, origination year and internal risk rating as of September 30, 2023 and December 31, 2022. The current year vintage table reflects gross charge-offs by loan portfolio 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.

The weighted average loan-to-value of collateral dependent loans was approximately 61% at September 30, 2023 and 42% at December 31, 2022.
Loan Modifications to Borrowers Experiencing Financial Difficulty
We adopted ASU No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures on January 1, 2023, as described in Note 2, Recently Adopted and Issued Accounting Standards. The amendments eliminated the accounting guidance for troubled debt restructurings and enhanced disclosures related to certain types of loan modifications for borrowers experiencing financial difficulty, including principal forgiveness, interest rate reductions, other-than-insignificant payment delays, and/or term extensions which are intended to minimize the economic loss and avoid foreclosure or repossession of collateral.

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 $1.299 billion and $1.298 billion at September 30, 2023 and December 31, 2022, respectively. In addition, we pledge eligible TIC loans, which totaled $108.5 million and $105.0 million at September 30, 2023 and December 31, 2022, 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 $6.3 million at September 30, 2023 and $6.4 million at December 31, 2022. In addition, undisbursed commitments to related parties totaled $562 thousand at both September 30, 2023 and December 31, 2022.
Note 6: Short-Term Borrowings and Other Obligations
Federal Home Loan Bank – As of September 30, 2023 and December 31, 2022, the Bank had total lines of credit with the FHLB totaling $1.023 billion and $711.6 million, respectively, based on eligible collateral of certain loans and investment securities.
Federal Funds Lines of Credit – The Bank had unsecured lines of credit with correspondent banks for overnight borrowings totaling $135.0 million and $150.0 million at September 30, 2023 and December 31, 2022, respectively. In general, interest rates on these lines approximate the federal funds target rate.
Federal Reserve Bank – The Bank has a line of credit with the Federal Reserve Bank of San Francisco ("FRBSF") secured by certain residential loans. At September 30, 2023 and December 31, 2022, the Bank had total borrowing capacity under this line of $57.3 million and $58.7 million, respectively. In addition, under the Federal Reserve’s BTFP facility, the Bank could borrow up to an additional $274.6 million based on the par value of pledged investment securities as of September 30, 2023.
Other Obligations – Finance lease liabilities totaling $335 thousand and $439 thousand at September 30, 2023 and December 31, 2022, respectively, are included in short-term borrowings and other obligations in the consolidated statements of condition. See Note 8, Commitments and Contingencies, for additional information.
Outstanding balances and weighted average interest rates on short-term borrowings and other obligations as of September 30, 2023 and December 31, 2022 are summarized in the following table.

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 (loss) 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 nine months ended September 30, 2023, we withheld 3,132 shares totaling $86 thousand at a weighted-average price of $27.57 for cashless exercises. During the nine months ended September 30, 2022, we withheld 11,505 shares totaling $393 thousand at a weighted-average price of $34.13 for cashless exercises. Shares withheld under net settlement arrangements are available for future grants.
Share Repurchase Program
Bancorp had an approved share repurchase program with $34.7 million remaining that expired on July 31, 2023. On July 21, 2023, the Board of Directors approved the adoption of Bancorp's new share repurchase program, which replaced the existing one at that time, for up to $25.0 million and expiring on July 31, 2025. There have been no repurchases in 2023.
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.
Page-25

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) | September 30, 2023 | December 31, 2022
Commercial lines of credit | $ | 260,117 |  | $ | 292,204 |
Revolving home equity lines | 220,148 |  | 218,907 |
Undisbursed construction loans | 17,881 |  | 43,179 |
Personal and other lines of credit | 9,268 |  | 10,842 |
Standby letters of credit | 2,757 |  | 1,738 |
Total unfunded loan commitments and standby letters of credit | $ | 510,171 |  | $ | 566,870 |

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 $1.1 million and $1.5 million as of September 30, 2023 and December 31, 2022, respectively, which is included in interest payable and other liabilities in the consolidated statements of condition. We recorded no provision for credit losses on unfunded loan commitments in the third quarters of 2023 and 2022. The $342 thousand reversal of the provision for credit losses on unfunded loan commitments in the nine months of 2023 was due primarily to a decrease in total unfunded commitments, compared to a $318 thousand provision reversal in the nine months of 2022, due to improved economic forecasts at the time.
Leases
We lease premises under long-term non-cancelable operating leases with remaining terms of 7 months to 18 years, 8 months, 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.

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"). We sold our remaining shares on July 13, 2023, however 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 or, per the terms of the sale, to the recent purchaser of our shares. Visa established an escrow account for the Covered Litigation that it periodically funds, which is expected to cover the settlement payment obligations.
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
The Bank is exposed to certain risks from both its business operations and changes in economic conditions. As part of our asset/liability and interest rate risk management strategy, we may enter into interest rate derivative contracts to modify the repricing characteristics of certain of our interest-earning assets and interest-bearing liabilities. The Bank generally designates interest rate hedging agreements utilized in the management of interest rate risk as either fair value hedges or cash flow hedges.
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.
On July 7, 2023, the Bank entered into various interest rate swap agreements with notional values totaling $101.8 million split evenly between terms of 2.5 and 3.0 years to hedge balance sheet interest rate sensitivity and protect certain of our fixed rate available-for-sale securities against changes in fair value related to changes in the benchmark interest rate. The interest rate swaps involve the receipt of floating rate interest from a counterparty in exchange for us making fixed-rate interest payments over the lives of the agreements, without the exchange of the underlying notional values. The transactions were designated as partial term fair value hedges and structured such that the changes in fair value of the interest rate swaps are expected to be perfectly effective in offsetting the changes in the fair value of the hedged items attributable to changes in the SOFR OIS swap rate, the designated benchmark interest rate. Because the hedges met the criteria for using the shortcut method, there is no need to periodically reassess effectiveness during the term of the hedges. For fair value designated hedges, the gain or loss on the hedging instruments as well as the offsetting loss or gain on the hedged items, are recognized in current earnings as fair values change.
In addition, we had four interest rate swap agreements on certain loans with our customers, which are scheduled to mature at various dates ranging from January 2026 to October 2037. The loan interest rate swaps were designated as fair value hedges and allowed 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 SOFR index, protects us against changes in the fair value of our loans associated with fluctuating interest rates. The notional amounts of the interest rate contracts are equal to the notional amounts of the hedged loans.

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 unaudited consolidated financial statements in this Form 10-Q and with the audited consolidated financial statements and accompanying notes included in our 2022 Annual Report on Form 10-K. Average balances, including balances used in calculating certain financial ratios, are generally comprised of average daily balances.
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 the war between Russia and Ukraine and more recently the war between Israel and Hamas, 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; the impact of adverse developments at other banks, including bank failures, that impact general sentiment regarding the stability and liquidity of banks; 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 2022 Form 10-K as filed with the SEC, and ITEM 1A Risk Factors herein, 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, Fair Value Measurements, and Business Combinations. For a detailed discussion, refer to the Critical Accounting Estimates section of our 2022 Form 10-K filed with the SEC on March 16, 2023.

Executive Summary
We generated earnings of $5.3 million for the third quarter of 2023, compared to $4.6 million for the second quarter of 2023. Diluted earnings per share were $0.33 for the third quarter of 2023, compared to $0.28 for the preceding quarter. Earnings for the first nine months of 2023 totaled $19.3 million, compared to $33.7 million for the same period in 2022. Diluted earnings per share were $1.20 and $2.11 for the first nine months of 2023 and 2022, respectively. The 2023 earnings were impacted by the increased cost of interest bearing deposits catching up to market interest rates and higher average balances on borrowings.
The following are highlights of our operating and financial performance for the periods presented. Additional performance details can be found in the pages that follow.
•The third quarter tax-equi valent net interest margin increased 3 basis points to 2.48% from 2.45% in the previous quarter due primarily to higher rates on interest-bearing cash balances generated from securities sales. The tax-equivalent net interest margin for the nine months ended September 30, 2023 of 2.66% decreased 40 basis points fr om 3.06% for the same period in 2022, primarily due to higher deposit and borrowing costs, partially offset by higher interest rates on loans and investment securities. We continue to manage our balance sheet and interest rate risk position to the current interest rate environment, and sold an additional $55.0 million in available-for-sale securities in late October. The sales generated an after-tax loss of $1.5 million, which is expected to be earned back through incremental interest income and improvements to the net interest margin in less than one year.
•Deposits totaled $3.444 billion as of September 30, 2023, a decrease of $129.7 million f rom $3.573 billion at December 31, 2022. However, deposits increased $118.5 million over the prior quarter. Our experienced team of bankers continued to build upon our strong deposit franchise with consistent growth from proactive outreach to both existing and prospective customers in all of our markets. Average cost of deposits increased 25 basis points over the second quarter, from 0.69% to 0.94%. Average cost of deposits increased 55 basis points for the first nine months of 2023, compared to the same period in 2022, from 0.06% to 0.61%. We believe we are competitively aligned in regard to deposit pricing, helping to maintain deposit levels.
•Non-interest bearing deposits made up 47.7% of total deposits at September 30, 2023, compared to 51.5% at December 31, 2022. We have successfully maintained non-interest bearing deposit percentages consistent with pre-pandemic levels, despite market and industry turbulence. Customer participation in the reciprocal deposit network program grew to $483.3 million maintaining estimated uninsured and/or uncollateralized deposits at 29% of total deposits as of September 30, 2023. Our largest depositor represented 2.7% of total deposits as of September 30, 2023.
•Borrowings totaled $120.0 million as of September 30, 2023, an $8.0 million increase from $112.0 million at December 31, 2022. However, total borrowings declined $52.2 million quarter-over-quarter from $172.2 million as a result of deposit growth and cash flows from investments and loans. Net available funding sources of $2.1 billion provided 211% coverage of an estimated $989.8 million in uninsured deposits at September 30, 2023.
•Our loan portfolio continues to perform well with classified loans at 1.90% of total loans. Non-owner-occupied commercial real estate loans made up $23.6 million or 59% of total classified loans as of September 30, 2023, compared to $22.0 million or 78% at December 31, 2022. Shortly after quarter-end three unsecured commercial substandard loans to one borrower totaling approximately $4.6 million paid off.
•Non-accrual loans were 0.27% of total loans, or $5.7 million, at September 30, 2023, compared to 0.12%, or $2.4 million, at December 31, 2022. Of the seven loans totaling $5.3 million moved to non-accrual status during the year, one legacy acquired-bank agricultural loan totaling $3.8 million became current on outstanding payments shortly after quarter-end. Offsetting the additions were payoffs and paydowns of $1.8 million and two loans for $314 thousand that were moved to accrual status in the first quarter. All of the non-accrual loans are collateralized by real estate with no expected credit loss as of September 30, 2023.
Page-31

•A $425 thousand provision for credit losses on loans in the third quarter brought the allowance for credit losses to 1.16% of total loans as of September 31, 2023. The provision was due primarily to qualitative risk factor adjustments as discussed further below and compared to a provision of $500 thousand in the previous quarter. For nine months ended September 30, 2023, we recorded a provision for credit losses on loans of $1.3 million, compared to a rev ersal of $63 thousand for the same period in 2022.
•Loans totaled $2.087 billion at September 30, 2023, a decrease of $5.6 million from $2.093 billion at December 31, 2022 reflecting originations of $90.3 million and payoffs of $59.5 million (including PPP payoffs). L oan amortization from scheduled repayments totaling $60.6 million was partially offset by a $24.2 million net increase in utilization of credit lines in the nine months ended September 30, 2023.
•Return on average assets ("ROA") was 0.52% for the third quarter of 2023, compared to 0.44% for the second quarter of 2023. Return on average equity ("ROE") was 4.94% for the third quarter of 2023, compared to 4.25% for the prior quarter. ROA was 0.63% for the nine months ended September 30, 2023, compared to 1.04% in the same period in 2022. ROE was 6.07% for the nine months ended September 30, 2023, compared to 10.65% in the same period in 2022. The efficiency ratio for the third quarter of 2023 was 72.96%, compared to 76.91% for the prior quarter. The efficiency ratio was 69.37% for the nine months ended September 30, 2023, compared to 55.60% in the same period in 2022.
•All capital ratios were above well-capitalized regulatory requirements. The total risk-based capital ratios at September 30, 2023 for Bancorp and the Bank were 16.6% and 16.1%, respectively. Bancorp's tangible common equity to tangible assets ("TCE ratio") was 8.6% at September 30, 2023, compared to 8.2% as of December 31, 2022. As of September 30, 2023, Bancorp's TCE ratio, net of after tax unrealized losses on held-to-maturity securities, was 6.1%, compared to 6.2% at December 31, 2022 (ref er to page 46 for a dis cussion and reconciliation of this non-GAAP financial measure).
•The Board of Directors declared a cash dividend of $0.25 per share on October 20, 2023, which represents the 74 th consecutive quarterly dividend paid by Bancorp. The dividend is payable on November 10, 2023, to shareholders of record at the close of business on November 3, 2023.
•As previously announced, David Bloom, Executive Vice President and Head of Commercial Banking, joined the Bank on July 31 and is responsible for the direction, vision, growth, and performance of the Bank’s commercial banking division, including its eight regional offices located throughout northern California and its specialty wine business. He previously served as senior managing director of business banking in northern California and the Pacific Northwest at First Republic Ban k. Under David's direction we have alre ady approved for fu nding loan amounts exceeding third quarter originations since quarter end.
•Also as previously announced, effective October 20, 2023, the Board of Directors for Bank of Marin Bancorp appointed Cigdem Gencer to its board, increasing its membership to thirteen directors. Gencer brings extensive leadership and financial services experience to the Board. Throughout her career, she has developed and executed transformative growth, expansion, and investment strategies for organizations, including international expansion efforts. For nearly two decades, Gencer served as executive vice president at a Fortune 500 financial institution where she served as head of international human resources, head of enterprise data strategy and analytics in the Chief Data Office, and chief financial officer, chief operating officer, and regional sales director for its Private Wealth division. Her experience also includes serving as a management consultant in the financial services sector and chief financial officer at Intrax, Inc. In 2021, she established Fazilet Consulting—an executive coaching and organizational consulting firm—in which she also serves as an executive coach.

Net Interest Income
Net interest income is the interest earned on loans, investments 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.

Third Quarter of 2023 Compared to the Second Quarter of 2023
Net interest income totaled $24.5 million for the third quarter of 2023, compared to $24.1 million for the prior quarter. The $339 thousand increase from the prior quarter was primarily related to an increase of approximately $358 thousand in interest income from the investment of securities sales proceeds into interest-bearing cash. The $2.3 million reduction in borrowing cost for the quarter was offset by rising deposit rates and higher average deposit balances that resulted in an additional $2.4 million in interest expense.
The tax-equivalent net interest margin was 2.48% for the third quarter of 2023, compared to 2.45% for the prior quarter. The increase from prior quarter was primarily due to a $73.3 million increase in avera ge interest-bearing cash balances with an average yield of 5.37% from securities sales proceeds. During the third quarter n ew loans were originated at rates approximately 150 basis points above the rates on loans paid off, which will positively impact the margin in future periods.
Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022
Net interest income totaled $78.5 million for the nine months ended September 30, 2023, compared to $94.1 million for the same period in the prior year. The $15.6 million decrease from prior year was primarily due to higher funding costs of $23.9 million, partially offset by higher average yields on earning assets.
The tax-equivalent net interest margin was 2.66% for the nine months ended September 30, 2023, compared to 3.06% for the same period in the prior year. The decrease was primarily attributed to higher deposit and borrowing costs, partially offset by higher interest rates on loans and investment securities. Average interest-bearing deposits balances decreased by $164.2 million while the average cost increased by 55 basis points, mainly for money market and time deposit account types, decreasing the margin by 46 basis points. Average borrowings and other obligations increased by $260.6 million at an average cost of 5.14%, an increase of 4.43%, decreasing the margin by 34 basis points. Average loan balances decreased by $87.3 million while the average yield increased by 36 basis points, increasing the margin by 20 basis points. Average investment securities increased $26.2 million and their average yield increased 31 basis points, increasing the margin by 19 basis points.
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 the evolving risks to economic activity caused by the COVID-19 pandemic, the FOMC made two emergency federal funds rate cuts totaling 150 basis points in March 2020. The federal funds rate range remained between 0.0% to 0.25% through the beginning of 2022, putting downward pressure on our asset yields and net interest margin. Beginning in March 2022, the FOMC began successive increases to the federal funds rate due to the evolving inflation risks, complicated by international political unrest and supply chain disruptions. As a result of seven rate adjustments during 2022, the federal funds target rate increased to a range of 4.25% to 4.50% at year-end 2022 and our net interest margin increased gradually over the course of the year. In 2023, on each of February 1 st, March 22 nd, May 3 rd, and July 26 th the FOMC increased the target rate by 25 basis points to a range of 5.25% to 5.50%. Rising interest rates and first quarter disruptions in the banking industry resulted in rapid increases in the cost of funds through rising deposit costs and increased borrowings, putting pressure on net interest margin in the second and third quarters. Federal Reserve policymakers continue to monitor inflation and economic developments throughout 2023. 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.

Provision for (reversal of) credit losses on loans | $ | 425 |  | $ | 500 |  |  |  | $ | 1,275 |  | $ | (63) |

We recorded a $425 thousand provision for credit losses on loans in the third quarter. The provision was due primarily to increases in qualitative factors related to trends in adversely graded, non-owner-occupied commercial real estate loans and the potential impact of rapidly increasing interest rates and other external factors on both our non-owner-occupied commercial real estate and construction portfolios. These increases were partially offset by the impact of the decrease in loan balances.
We recorded a $500 thousand provision for credit losses on loans in the second quarter. The provision was due primarily to increases in qualitative risk factors from continued negative trends in adversely graded loans and/or collateral values on our non-owner occupied commercial real estate office and multi-family real estate portfolios. These increases were partially offset by the impact of a decrease in loan balances.
The provision totaling $1.3 million for the nine months ended September 30, 2023 primarily resulted from increases in qualitative risk factors from continued trends in adversely graded loans and/or collateral values not believed to be captured in the quantitative risk factors.
The net provision reversal for the nine months ended September 30, 2022 primarily resulted from a provision reversal in the first quarter due to improvements in the economic forecasts, partially offset by the provision in the third quarter due primarily to an increase in qualitative factors to account for the ongoing deterioration in the economic outlook not captured in the quantitative portion of the allowance.

Third Quarter of 2023 Compared to the Second Quarter of 2023
Non-interest income totaled $2.6 million for the third quarter of 2023, compared to $2.7 million for the prior quarter. The $141 thousand decrease from the prior quarter was primarily related to the decrease in debit card interchange income.
Nine Months Ended September 30, 2023 Compared to Nine Months Ended September 30, 2022
Non-interest income totaled $8.3 million for the nine months ended September 30, 2023, materially unchanged from the same period of the prior year. The $46 thousand decrease from the prior year period was mostly attributable to decreases in other income including one-way deposit and cash management fees and in wealth management and trust services income, partially offset by higher bank-owned life insurance benefit payments and balances and dividends on Federal Home Loan Bank stock.

Third Quarter of 2023 Compared to the Second Quarter of 2023
Non-interest expense totaled $19.7 million for the third quarter of 2023, compared to $20.7 million for the prior quarter. Th e $918 thousand decrease from the prior quarter primarily resulted from a $675 thousand decrease in salaries and related benefits mainly due to decreases in accrued incentive and profit sharing expenses and 401(k) contributio ns, $618 thousand less in charitable contributions as our annual grant program normally occurs in the second quarter, and a $197 thousand decrease related to a catch-up adjustment in the second quarter for increased FDIC assessments to strengthen the Deposit Insurance Fund. These decreases were partially offset by a $532 thousand net increase in other expense, primarily due to a $688 thousand increase in expenses and fees associated with our customers' participation in reciprocal deposit networks to bolster their FDIC insured balances.

Non-interest expense totaled $60.2 million for the nine months ended September 30, 2023, compared to $57.0 million for the nine months ended September 30, 2022, an increase of $3.2 million. Other expense increased by $1.8 million primarily due to a $1.5 million increase in expenses and fees associated with reciprocal deposits placed into deposit networks. Salaries and related benefits increased by $641 thousand primarily due to regularly scheduled annual merit and other increases, the hiring of several key employees and officers, and lower deferred loan origination costs, partially offset by a reduction in accrued incentive and profit sharing expenses. Occupancy and equipment and depreciation and amortization expenses rose $628 thousand and $446 thousand, respectively, mainly from the acceleration of lease-related costs for branch closures in the first quarter of 2 0 23. Beginning in 2024, the estimated annual pre-tax savings from branch closures are expected to be approximately $1.4 million. I n addition, the FDIC insurance assessment rose by $538 thousand due to the increased statutory rate. These increases were partially offset by a $593 thousand decrease in data processing expenses due to our core system contract renegotiation for the current period and because the prior year included data processing expenses largely eliminated after the systems conversion associated with the American River Bankshares merger. In addition, other real estate owned expenses decreased by $307 thousand due the write-down in the prior year of the asset that was sold in the third quarter of 2023.
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, bank-owned life insurance ("BOLI") income, 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 third quarter of 2023 totaled $1.6 million at an effective tax rate of 23.2%, compared to $1.3 million at an effective tax rate of 22.5% in the prior quarter. The increase in the provision for income taxes in the third quarter of 2023 reflected higher pre-tax income as compared to the prior quarter. The 70 basis point increase in the effective tax rate in the third quarter of 2023 was primarily due to the smaller proportional effect of permanent tax differences on higher pretax income.
The provision for income taxes for the first nine months of 2023 totaled $6.4 million at an effective tax rate of 24.8%, compared to $12.2 million at an effective tax rate of 26.5% for the first nine months of 2022. The 170 basis point decrease in the effective tax rate in the first nine months of 2023, as compared to the same period a year ago, was primarily due to the larger proportional effect of permanent tax differences on lower pretax income and higher tax-exempt BOLI income. This decrease was partially offset by a reduction in the tax-exempt interest exclusion (due to a larger IRC Section 291(e) interest expense disallowance), compared to the prior period.
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 September 30, 2023, neither the Bank nor Bancorp had accruals for interest or penalties related to unrecognized tax benefits.

FINANCIAL CONDITION SUMMARY
Cash, Cash Equivalents and Restricted Cash
Total cash, cash equivalents and restricted cash were $123.1 million at September 30, 2023, compared to $45.4 million at December 31, 2022. The $77.7 million increase was due primarily to the sale of $82.7 million of available-for-sale securities in the third quarter, which resulted in 3 basis points of net interest margin expansion due to the higher interest rate earned on cash and provided diversification to our liquidity profile.
Investment Securities
The investment securities portfolio totaled $1.594 billion at September 30, 2023, a decrease of $180.3 million from $1.774 billion at December 31, 2022. The decrease was primarily the result of principal repayments and maturities totaling $87.7 million, sales of $82.7 million available-for-sale securities, an increase of $5.7 million in pre-tax unrealized losses on available-for-sale investment securities, and $4.2 million in net amortization in the first nine months of 2023. The securities sales and $102 million fair value hedge reduced the impact of interest rate increases on tangible capital over the quarter by approximately 7 basis points. The $2.8 million net loss on the sale of securities was offset by a $2.8 million gain from the sale of our remaining investment in Visa Inc. Class B restricted common stock, which had a zero carrying value. B oth the available-for-sale and held-to-maturity portfolios are eligible for pledging to either the FHLB or the Federal Reserve as collateral for borrowing. The portfolios are comprised of high credit quality investments with average effective durations of 4.07 on available-for-sale securities and 5.95 on held-to-maturity securities. Both portfolios generate cash inflows monthly from interest, principal amortization and payoffs, which supports the Bank's liquidity. Those cash inflows t otaled $123.9 million in the first nine months of 2023.
The following table summarizes our investment in obligations of state and political subdivisions at September 30, 2023 and December 31, 2022.

|  | September 30, 2023 |  | December 31, 2022
(dollars in thousands) | Amortized Cost | Fair Value | % of Total State and Political Subdivisions |  | Amortized Cost | Fair Value | % of Total State and Political Subdivisions

Percent of investment portfolio | 9.7 | % | 9.3 | % |  |  | 9.6 | % | 9.3 | % |

Of the total investment in obligations of state and political subdivisions, the largest concentrations outside of California are in Texas (37.1%), Washington (15.4%) and Wisconsin (9.0%). 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).
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
Page-40

•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 and Credit Quality
During the first nine months of 2023, loans decreased by $5.6 million and totaled $2.087 billion at September 30, 2023, compared to $2.093 billion at December 31, 2022. During the same period in 2022, loans decreased $97.3 million to $2.158 billion at September 30, 2022 from $2.256 billion at December 31, 2021. Loan originations were $90.3 million for the nine months ended September 30, 2023, compared to $204.1 million for the first nine months of 2022. Excluding PPP loans, payoffs were $57.7 million for the nine months ended September 30, 2023, compared to $204.2 million for the same period in 2022. PPP loan payoffs during the nine months ended September 30, 2023 and 2022 were $1.8 million and $103.6 million, respectively. In addition, loan amortization from scheduled repayments totaling $60.6 million was partially offset by a $24.2 million net increase in utilization of credit lines for the nine months ended September 30, 2023. While Bank of Marin has continued its usual steadfast conservative underwriting practices and has not changed its credit standards or policies in reaction to current market conditions, our portfolio management and credit teams are exercising heightened awareness of the potential for credit quality deterioration. The Bank continues to focus on extending credit within the markets we know best and serving the needs of our existing clients while ensuring new opportunities present the appropriate levels of risk and return.
The ratio of allowance for credit losses on loans to total loans was 1.16% at September 30, 2023, compared to 1.10% at December 31, 2022.
Non-accrual loans increased $3.3 million to $5.7 million, or 0.27% of the loan portfolio at September 30, 2023 from $2.4 million, or 0.12% at December 31, 2022. All of the non-accrual loans are collateralized by real estate with no expected credit loss as of September 30, 2023. Accruing loans past due 30 to 89 days totaled $2.2 million at September 30, 2023, compared to $664 thousand at December 31, 2022.
Classified loans with risk ratings of substandard or doubtful totaled $39.7 million at September 30, 2023, compared to $28.1 million at December 31, 2022. Increases in 2023 were primarily due to the addition of eleven loans to ten borrowers totaling $13.4 million, mostly within the commercial real estate (both owner-occupied and non-owner occupied) and the commercial and industrial portfolios. Partially offsetting the additions were $939 thousand in upgrades to pass risk rating and $905 thousand in payoffs and paydowns, net of balance increases of $3.4 million. Shortly after quarter-end three unsecured commercial substandard loans to one borrower totaling approximately $4.6 million paid off.
Loans designated special mention, which are not considered adversely classified, increased by $52.2 million to $112.4 million at September 30, 2023 from $60.2 million at December 31, 2022. The increase was largely due to $66.0 million in downgrades from pass risk ratings, mostly concentrated in the commercial real estate non-owner-occupied portfolio, which were partially offset by $5.9 million in downgrades from special mention to substandard, $4.9 million in paydowns and payoffs and $3.1 million in upgrades to pass risk ratings.
With the heightened market concern about non-owner-occupied commercial real estate, and in particular the office sector, we are providing the following additional information. We continue to maintain diversity among property types and within our geographic footprint. In particular, our office commercial real estate portfolio in the City of San Francisco represents just 3% of our total loan portfolio and 6% of our total non-owner occupied commercial real estate portfolio. As of the last measurement period (generally December 2022), the weighted average loan-to-value and weighted average debt-service coverage ratios for the entire non-owner-occupied office portfolio were 56% and 1.68x, respectively. For the eleven non-owner-occupied office loans in the City of San Francisco, the weighted average loan-to-value and debt-service coverage ratios were 66% (61% unweighted) and 1.07x (1.34x unweighted), respectively. During the quarter we conducted a review of the refinance risk in our non-owner-occupied commercial real estate portfolio. We evaluated 36 loans with commitments of $1.0 million or more totaling $97.4 million that mature or reprice in 2023 or 2024 and determined that the refina nce risk on these loans is expected to be manageable with weighted average debt service coverage ratios ranging from 1.28 to 2.01 times based on current interest rates.

Liabilities - Deposits and Borrowings
During the first nine months of 2023, total liabilities decreased by $118.4 million to $3.617 billion. Deposits totaled $3.444 billion at September 30, 2023, a decrease of $129.7 million compared to $3.573 billion at December 31, 2022. Borrowings increased $8.0 million to $120.0 million at September 30, 2023 from $112.0 million at December 31, 2022.
We have seen stability in deposit trends since the first quarter, including the utilization of our available deposit networks. That stability extended to our mix in deposits, new account activity and overall growth. Non-interest bearing deposits made up 47.7% of total deposits at September 30, 2023, compared to 51.5% at year-end 2022, while money market deposits rose to 31.7% from 27.7%, and time deposits rose to 6.7% from 3.3% in the same period. Additionally, the Bank's competitive and balanced approach to relationship management and focused outreach supported the growth adding over 1,200 new accounts during the third quarter, 38% of which were new relationships, bringing the total to over 3,600 new accounts in 2023 (excluding new reciprocal accounts). As a result, we are closing the gap on the deposit outflows experienced in the first quarter of 2023 without accessing brokered deposit markets. As of September 30, 2023, 61% of deposit balances were held in business accounts with average balances of $130 thousand per account. The remaining 39% were consumer accounts with average balances of $41 thousand per account. The largest depositor represented 2.7% of total deposits and the four largest depositors combined represented 5.3% of total deposits. Our liquidity policies require that compensating cash or investment security balances be held against concentrations over a certain level.
At September 30, 2023, the Bank had $120.0 million outstanding in short term borrowings from the Federal Reserve Bank's "BTFP" facility at a rate of 5.42%, an increase of $8.0 million, compared to $112.0 million in overnight borrowings at December 31, 2022 at a rate of 4.65%. The Bank is actively evaluating strategies for reducing borrowings in the current environment and as market conditions change. Total immediate contingent funding sources, including unrestricted cash, unencumbered available-for-sale securities, and remaining borrowing capacity was $2.086 billion, or 61% of total deposits and 211% of estimated uninsured and/or uncollateralized deposits as of September 30, 2023.
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 September 30, 2023. 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.

Bancorp's TCE ratio was 8.6% at September 30, 2023, compared to 8.2% at December 31, 2022. Bancorp's TCE ratio, net of after tax unrealized losses on held-to-maturity securities, was 6.1%, compared to 6.2% at December 31, 2022. Management believes this non-GAAP measure is important because it reflects the level of capital available to withstand drastic changes in market conditions (ref er to page 46 for a dis cussion and reconciliation of this non-GAAP financial measure).
The Bancorp’s and Bank’s capital adequacy ratios as of September 30, 2023 and December 31, 2022 are presented in the following tables.

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 seen in the table below and 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 Bank directors and the Bank's Chief Executive Officer, is responsible for approving and monitoring our liquidity targets and strategies. The Bank has long-established minimum liquidity and diversification requirements using tools similar to larger banks such as the Liquidity Coverage Ratio and multi-scenario, long-horizon stress testing. Our c on tingency funding plan provides for 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 $2.2 million in off-balance sheet one-way deposit sales with our deposit networks at both September 30, 2023 and December 31, 2022.
Net available contingent funding sources, including unrestricted cash, unencumbered available-for-sale securities and total available borrowing capacity was $2.086 billion, or 211% of estimated uninsured and/or uncollateralized deposits as of September 30, 2023. The Federal Reserve's BTFP facility offers borrowing capacity based on par values of securities pledged making it less sensitive to changes in market rates. The following table details the components of our contingent liquidity sources as of September 30, 2023.

1 Excludes cash items in transit.
Note: Brokered deposits available through third party networks are not included above.
We obtain funds from the repayment and maturity of loans, deposit inflows, investment securities sales, 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, dividends to common stockholders, and operating expenses.
Customer deposits are a significant component of our daily liquidity position. The attraction and retention of new deposits depend upon the variety and effectiveness of our customer account products, service and 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 increased $77.7 million in the first nine months of 2023. The most significant sources of liquidity during the first nine months of 2023 were proceeds from principal paydowns and maturities of investment securities of $87.8 million, proceeds from the sales of $82.7 million of available-for-sale securities and the remaining Visa Inc. Class B restricted common stock in the third quarter, and $34.9 million in net cash provided by operating activities. 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, as detailed in this report, and contingent funding sources outlined in the table above are adequate to support our operational needs.
Significant uses of liquidity during 2023 were $129.7 million in net withdrawals of deposits and $12.1 million in cash dividends paid on common stock to our shareholders.
Unfunded loan commitments, as discussed in Note 8 to the Consolidated Financial Statements in this Form 10-Q, totaled $510.2 million at September 30, 2023. We expect to fund these commitments to the extent utilized primarily through the repayment of existing loans, principal paydowns of investment securities, and liquid assets.
Over the next twelve months, $210.2 million of time deposits will mature. We expect to replace these funds with new deposits or excess liquidity. We believe our emphasis on local deposits, combined with our immediately available funding sources, provides a very stable base for our liquidity needs.
We had borrowings under our credit facilities of $120.0 million at September 30, 2023, and $112.0 million at December 31, 2022, as discussed in Note 6 to the Consolidated Financial Statements in ITEM 1 of this report.
Because 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 $11.5 million in cash at September 30, 2023 and 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.

Statement Regarding use of Non-GAAP Financial Measures
Results for 2022 we re impacted by costs associated with our 2021 acquisition of American River Bankshares, which we considered immaterial to discuss in this report. For additional information regarding the impact of non-GAAP adjustments to our third quarter and year-to-date 2022 performance measures, refer to Form 10-Q filed on November 8, 2022.
Financial results are presented in accordance with GAAP and with reference to certain non-GAAP financial measures. Management believes that, given recent industry turmoil, the presentation of Bancorp's non-GAAP TCE ratio reflecting the after-tax impact of unrealized losses on held-to-maturity securities provides useful supplemental information to investors because it reflects the level of capital available to withstand drastic changes in market conditions. Because there are limits to the usefulness of this measure to investors, Bancorp encourages readers to consider its annual and quarterly consolidated financial statements and notes related thereto in their entirety, as filed with the Securities and Exchange Commission, and not to rely on any single financial measure. A reconciliation of the non-GAAP TCE ratio is presented below.

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 and 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 selected investment securities and 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 in the context of policy guidelines. 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
Page-45

value and net interest income 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. Governing policies are subject to review by regulators and are updated to incorporate their observations and to adapt to changes in idiosyncratic and systemic risks. At September 30, 2023, 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 | (0.4) | % | 4.2 | %
up 300 | (0.4) | % | 3.0 | %
up 200 | (0.3) | % | 1.8 | %
up 100 | — | % | 1.3 | %
down 100 | 1.2 | % | (1.3) | %
down 200 | 3.6 | % | (0.4) | %
down 300 | 6.1 | % | — | %
down 400 | 7.0 | % | (1.4) | %

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, lower deposit growth than modeled may cause the Bank to increase its borrowing position, thereby increasing its liability sensitivity. 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. The above tables reflect deposit betas of u p to 45%, averaging 36%, to rates paid on non-maturity interest-bearing deposits in rising rate scenarios. 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
During the quarter ended September 30, 2023, there were no significant changes that materially affected, or were reasonably likely to affect, our internal control over financial reporting. The term internal control over financial reporting, as defined by Rule 15d-15(f) of the Act, is a process designed by, or under the supervision of, the issuer's principal executive and principal financial officers, or persons performing similar functions, and effected by the issuer's board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.
PART II OTHER INFORMATION
ITEM 1 Legal Proceedings
Refer to Note 12 to the Consolidated Financial Statements in Item 8 of our 2022 Form 10-K and Note 8 to the Consolidated Financial Statements in this Form 10-Q.
ITEM 1A Risk Factors
Our business is influenced by many factors that are difficult to predict, involve uncertainties that may materially affect actual results and are often beyond our control. In evaluating an investment in Bancorp's common stock, investors should consider, among other things, the risks previously disclosed in Part I, Item 1A, "Risk Factors" of our 2022 Form 10-K, and the information contained in this quarterly report on Form 10-Q and other reports and registration statements filed w ith the SEC, which are incorporated herein by reference. Other than as noted below, there have been no material changes in the risk factors disclosed in our 2022 Form 10-K.
Recent Negative Developments Affecting the Banking Industry and Resulting Media Coverage Have Eroded Customer and Investor Confidence in the Banking System
High-profile 2023 bank failures involving Silicon Valley Bank and Signature Bank in the first quarter, and First Republic Bank in the second quarter, as well as media and market coverage of the Bay Area economy and local financial institutions, have generated significant market volatility among publicly traded bank holding companies and, in particular, regional and community banks like the Company. These market developments have negatively impacted customer confidence in the safety and soundness of regional and community banks. As a result, customers may choose to maintain deposits with larger financial institutions or invest in higher yielding short-term fixed income securities, all of which could materially adversely impact the Company’s liquidity, loan funding capacity, net interest margin, capital and results of operations. Additionally, these recent events have, and could continue to, adversely impact the market price and volatility of the Company’s common stock independent from the Company’s actual underlying financial performance.
Rising Interest Rates Have Decreased the Value of the Company’s Held-To-Maturity and Available-for-Sale Securities Portfolio, and the Company Would Realize Losses if It Were Required to Sell Such Securities to Meet Liquidity Needs
Because of inflationary pressures and the resulting rapid increases in interest rates over the last year, the trading value of previously issued government and other fixed income securities has declined significantly. These securities make up a majority of the securities portfolio of most banks in the U.S., including the Company’s, resulting in unrealized losses embedded in the held-to-maturity portion of U.S. banks’ securities portfolios and unrealized losses on available-for-sale securities reflected in the Company’s accumulated other comprehensive income. While it is not our intention to sell securities at a net loss, we may do so in the normal course of business as a source of liquidity or to reposition the balance sheet for strategic purposes as was done in the third quarter of 2023. If the Company were to sell additional securities in an unrealized loss position, it may incur losses that could impair the Company’s capital, financial condition, and results of operations and may require the Company to raise additional capital on unfavorable terms, thereby negatively impacting its profitability.
Any Regulatory Examination Scrutiny or New Regulatory Requirements Arising From the Recent Events in the Banking Industry Could Increase the Company’s Expenses and Affect the Company’s Operations
Page-47

The Company also anticipates increased regulatory scrutiny – in the course of routine examinations and otherwise – and new regulations directed towards banks of similar size to the Bank, designed to address the recent negative developments in the banking industry, all of which may increase the Company’s costs of doing business and reduce its profitability. As primarily a commercial bank, the Bank has a higher percentage of uninsured deposits compared to primarily retail focused banks. As a result, the Bank could face increased scrutiny or be viewed as higher risk by regulators and the investor community.
ITEM 2 Unregistered Sales of Equity Securities and Use of Proceeds
There were no unregistered sales of equity securities during the period covered by this report.
