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 affect our earnings in future periods. A number of factors—many of which are beyond Management’s control—could cause future results to vary materially from current Management expectations. Such factors include, but are not limited to, general economic conditions and the economic uncertainty in the United States and abroad, including changes in interest rates, deposit flows, real estate values, and expected future cash flows on loans and securities; integration of acquisitions and competition; changes in accounting principles, policies or guidelines; changes in legislation or regulation; adverse weather conditions, including the drought in California; and other economic, competitive, governmental, regulatory and technological factors affecting our operations, pricing, products and services.

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 of this report. 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.

ITEM 1 BUSINESS

Bank of Marin (the “Bank”) was incorporated in August 1989, received its charter from the California Superintendent of Banks (now the California Department of Business Oversight or "DBO") and commenced operations in January 1990. The Bank is an insured bank under the Federal Deposit Insurance Corporation (“FDIC”). On July 1, 2007 (the “Effective Date”), a bank holding company reorganization was completed whereby Bank of Marin Bancorp (“Bancorp”) became the parent holding company for the Bank, the sole and wholly-owned subsidiary of Bancorp. On the Effective Date, each outstanding share of Bank of Marin common stock was converted into one share of Bank of Marin Bancorp common stock. Bancorp is listed at NASDAQ under the ticker symbol BMRC, which was formerly used by the Bank. Prior to the Effective Date, the Bank filed reports and proxy statements with the FDIC pursuant to Section 12 of the 1934 Act. Upon formation of the holding company, Bancorp became subject to regulation under the Bank Holding Company Act of 1956, as amended, which subjects Bancorp to Federal Reserve Board reporting and examination requirements, and Bancorp now files 1934 Act reports with the Securities and Exchange Commission.

References in this report to “Bancorp” mean Bank of Marin Bancorp, parent holding company for the Bank. References to “we,” “our,” “us” mean the holding company and the Bank that are consolidated for financial reporting purposes.

Virtually all of our business is conducted through Bancorp's subsidiary, Bank of Marin, which is headquartered in Novato, California. In addition to our headquarters office, we operate through twenty offices in Marin, Sonoma, San Francisco, Napa and Alameda counties, with a strong emphasis on supporting the local communities. Our customer base is made up of business and personal banking relationships from the communities near the branch office locations. Our business banking focus is on small to medium-sized businesses, professionals and not-for-profit organizations.

We offer a broad range of commercial and retail deposit and lending programs designed to meet the needs of our target markets. Our lending categories include commercial real estate loans, commercial and industrial loans,

Page-4

construction financing, consumer loans, and home equity lines of credit. Merchant card services are available for our business customers. Through third party vendors, we offer a proprietary Visa^®credit card product combined with a rewards program to our customers, a Business Visa^® program, a leasing program for commercial equipment financing, and cash management sweep services.

We offer a variety of personal and business checking and savings accounts, and a number of time deposit alternatives, including time certificates of deposit, Individual Retirement Accounts (“IRAs”), Health Savings Accounts, Certificate of Deposit Account Registry Service^® ("CDARS") and Insured Cash Sweep^® ("ICS") accounts. CDARS and ICS are part of a network through which we offer full FDIC insurance coverage in excess of the regulatory maximum by placing deposits in multiple banks participating in the network. We also offer mobile banking, remote deposit capture, Automated Clearing House services (“ACH”), fraud prevention services including Positive Pay for Checks, ACH, Apple Pay^®, peer-to-peer funds transfer, and image lockbox services. A valet deposit pick-up service is available to our professional and business clients.

Automated teller machines (“ATM's”) are available at each retail branch location. Our ATM network is linked to the PLUS, CIRRUS and NYCE networks, as well as to a network of nation-wide surcharge-free ATM's called MoneyPass. We also offer our depositors 24-hour access to their accounts by telephone and through our internet banking products available to personal and business account holders.

We offer Wealth Management and Trust Services (“WMTS”) which include customized investment portfolio management, trust administration, estate settlement, custody services, and advice on charitable giving. We also offer 401(k) plan services to small and medium-sized businesses through a third party vendor.

We make international banking services available to our customers indirectly through other financial institutions with whom we have correspondent banking relationships.

We hold no patents, licenses (other than licenses required by the appropriate banking regulatory agencies), franchises or concessions. The Bank has registered the service marks "The Spirit of Marin", the words “Bank of Marin”, the Bank of Marin logo, and the Bank of Marin tagline “Committed to your business and our community” with the United States Patent & Trademark Office. In addition, Bancorp has registered the service marks for the words “Bank of Marin Bancorp” and for the Bank of Marin Bancorp logo with the United States Patent & Trademark Office.

All service marks registered by Bancorp or the Bank are registered on the United States Patent & Trademark Office Principal Register, with the exception of the words "Bank of Marin Bancorp" which is registered on the United States Patent & Trademark Office Supplemental Register.

Market Area

Our primary market area consists of Marin, San Francisco, Napa, Sonoma and Alameda counties. Our customer base is primarily made up of business, not-for-profit and personal banking relationships within these market areas.

We attract deposit relationships from individuals, merchants, small to medium-sized businesses, not-for-profit organizations and professionals who live and/or work in the communities comprising our market areas. As of December 31, 2015, approximately 67% of our deposits are in Marin County and southern Sonoma County, and approximately 56% of our deposits are from businesses and 44% from individuals.

Competition

The banking business in California generally, and in our market area specifically, is highly competitive with respect to attracting both loan and deposit relationships. The increasingly competitive environment is affected by changes in regulation, interest rates, technology and product delivery systems, and consolidation among financial service providers. The banking industry is seeing strong competition for quality loans, with larger banks expanding their activities to attract businesses that are traditionally community bank customers. In all of our five counties, we have significant competition from nationwide banks with much larger branch networks and greater financial resources, as well as credit unions and other independent banks.

Page-5

In Marin County we have the third largest market share of total depositsat 10.1%, according to the Deposit & Market Share Report from the California Banksite Corporation based upon the FDIC deposit market share data as of June 30, 2015. A significant driver of our franchise value is the growth and stability of our checking deposits, a low-cost funding source for our loan portfolio. We are building our presence in the Sonoma, Napa, Alameda and San Francisco markets.

Other competitors for depositors' funds are money market mutual funds and non-bank financial institutions such as brokerage firms and insurance companies. Among the competitive advantages held by some of these large, non-bank financial institutions is their ability to finance extensive advertising and funding campaigns.

Nationwide banks have the competitive advantages of national advertising campaigns and technology infrastructure to achieve economies of scale. Large commercial banks also have substantially greater lending limits and the ability to offer certain services which are not offered directly by us.

In order to compete with the numerous, and often larger, financial institutions in our primary market area, we use, to the fullest extent possible the flexibility and rapid response capabilities that derive from our independent status, local leadership and local decision making. Our competitive advantages also include an emphasis on personalized service, extensive community involvement, philanthropic giving, local promotional activities and strong relationships with our customers. The commitment and dedication of our directors, officers and staff have also contributed greatly to our success in competing for business.

Employees

At December 31, 2015, we employed 259 full-time equivalent (“FTE”) staff. The actual number of employees, including part-time employees, at year-end 2015 included five executive officers, 105 other corporate officers and 164 staff. None of our employees are presently represented by a union or covered by a collective bargaining agreement. We believe that our employee relations are good. We have been recognized as one of the “Best Places to Work” by the North Bay Business Journal and as a "Top Corporate Philanthropist” by the San Francisco Business Times for many years.

SUPERVISION AND REGULATION

Bank holding companies and banks are extensively regulated under both federal and state law. The following discussion summarizes certain significant laws, rules and regulations affecting Bancorp and the Bank.

Bank Holding Company Regulation

Upon formation of the bank holding company on July 1, 2007, we became subject to regulation under the Bank Holding Company Act of 1956, as amended (“BHCA”) which subjects Bancorp to Federal Reserve Board ("FRB") reporting and examination requirements. Under the FRB's regulations, a bank holding company is required to serve as a source of financial and managerial strength to its subsidiary banks. Under this requirement, we are expected to commit resources to support the Bank, including at times when we may not be in a financial position to provide such resources, and it may not be in our, or our shareholders’ or creditors’, best interests to do so. In addition, any capital loans we make to the Bank are subordinate in right of payment to depositors and to certain other indebtedness of the Bank. The BHCA regulates the activities of holding companies including acquisitions, mergers and consolidations and, together with the Gramm-Leach Bliley Act of 1999, the scope of allowable banking activities. Bancorp is also a bank holding company within the meaning of the California Financial Code. As such, Bancorp and its subsidiaries are subject to examination by, and may be required to file reports with, the DBO.

Bank Regulation

Banking regulations are primarily intended to protect consumers, depositors' funds, federal deposit insurance funds and the banking system as a whole. These regulations affect our lending practices, consumer protections, capital structure, investment practices and dividend policy.

As a state chartered bank, we are subject to regulation, supervision and examination by the DBO. We are also subject to regulation, supervision and periodic examination by the FDIC. If, as a result of an examination of the Bank, the

Page-6

FDIC or the DBO should determine that the financial condition, capital resources, asset quality, earnings prospects, management, liquidity, or other aspects of our operations are unsatisfactory, or that we have violated any law or regulation, various remedies are available to those regulators including issuing a “cease and desist” order, monetary penalties, restitution, restricting our growth or removing officers and directors.

The Bank addresses the many state and federal regulations it is subject to through a comprehensive compliance program that addresses the various risks associated with these issues.

Dividends

The payment of cash dividends by the Bank to Bancorp is subject to restrictions set forth in the California Financial Code (the “Code”) in addition to regulations and policy statements of the FRB. Prior to any distribution from the Bank to Bancorp, a calculation is made to ensure compliance with the provisions of the Code and to ensure that the Bank remains within capital guidelines set forth by the DBO and the FDIC. Management anticipates that there will be sufficient earnings at the Bank level to provide dividends to Bancorp to meet its cash requirements for 2016. See also Note 9 to the Consolidated Financial Statements, under the heading “Dividends” in Item 8 of this report.

FDIC Insurance Assessments

Our deposits are insured by the FDIC to the maximum amount permitted by law, which is currently $250,000 per depositor, based on the 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”).

Our FDIC insurance assessment base is quarterly average consolidated total assets minus average tangible equity, defined as Common Equity Tier 1 Capital. Assessment rates are between 2.5 and 9 basis points annually on the assessment base for banks in the lowest risk category and 30 to 45 basis points for banks in the highest risk category. In deriving the risk categories, the FDIC uses a bank's capital level, supervisory ratios and other financial measures to determine a bank's ability to withstand financial stress.

Community Reinvestment Act

The Community Reinvestment Act (“CRA”) was enacted in 1977 to encourage financial institutions to meet the credit needs of the communities where they are chartered. All banks and thrifts have a continuing and affirmative obligation, consistent with safe and sound operations, to help meet the credit needs of their entire communities, including low and moderate income neighborhoods. Regulatory agencies rate each bank's performance in assessing and meeting these credit needs. The Bank is committed to serving the credit needs of the communities in which we do business, and it is our policy to respond to all creditworthy segments of our market. As part of its CRA commitment, the Bank maintains strong philanthropic ties to the community. We invest in affordable housing funds that help economically disadvantaged individuals and residents of low- and moderate-income census tracts, in each case consistent with our long-established prudent underwriting practices. We also donate to and volunteer with organizations in our communities that serve small businesses or low-and moderate-income communities or individuals that offer educational and health programs to economically disadvantaged students and families, community development service and affordable housing programs. We provide CRA reportable small business, small farm and community development loans within our assessment areas. The CRA requires a depository institution's primary federal regulator, in connection with its examination of the institution, to assess the institution's record in meeting CRA requirements. The regulatory agency's assessment of the institution's record is made available to the public. The record is taken into consideration when the institution establishes a new branch that accepts deposits, relocates an office, applies to merge or consolidate, or expands into other activities. The FDIC's last CRA performance examination, completed in May 2015, was performed under the large bank requirements and was assigned a rating of “Satisfactory”.

Anti Money-Laundering Regulations

A series of banking laws and regulations beginning with the Bank Secrecy Act in 1970 requires banks to prevent, detect, and report illicit or illegal financial activities to the federal government to prevent money laundering, international drug trafficking, and terrorism. Under the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, financial institutions are subject to prohibitions against specified financial transactions and account relationships, requirements regarding the Customer Identification Program, as well as

Page-7

enhanced due diligence and “know your customer” standards in their dealings with high risk customers, foreign financial institutions, and foreign individuals and entities.

Privacy and Data Security

The Gramm-Leach Bliley Act (“GLBA”) of 1999 imposes requirements on financial institutions with respect to consumer privacy. The GLBA generally prohibits disclosure of consumer information to non-affiliated third parties unless the consumer has been given the opportunity to object and has not objected to such disclosure. Financial institutions are further required to disclose their privacy policies to consumers annually. The GLBA also directs federal regulators, including the FDIC, to prescribe standards for the security of consumer information. We are subject to such standards, as well as standards for notifying consumers in the event of a security breach. We must disclose our privacy policy to consumers and permit consumers to “opt out” of having non-public customer information disclosed to third parties. We are required to have an information security program to safeguard the confidentiality and security of customer information and to ensure proper disposal of information that is no longer needed. Customers must be notified when unauthorized disclosure involves sensitive customer information that may be misused.

Consumer Protection Regulations

Our lending activities are subject to a variety of statutes and regulations designed to protect consumers, including the CRA, Home Mortgage Disclosure Act, Fair Credit Reporting Act, Fair Lending, Equal Credit Opportunity Act, the Fair Housing Act, Truth-in-Lending Act ("TILA"), and the Real Estate Settlement Procedures Act ("RESPA"). Our deposit operations are also subject to laws and regulations that protect consumer rights including Expedited Funds Availability, Truth in Savings, and Electronic Funds Transfers. Other regulatory requirements include: the Unfair, Deceptive or Abusive Acts and Practices ("UDAAP"), Dodd-Frank Act, Right To Financial Privacy and Privacy of Consumer Financial Information. Additional rules govern check writing ability on certain interest earning accounts and prescribe procedures for complying with administrative subpoenas of financial records.

Restriction on Transactions between Bank's Affiliates

Transactions between Bancorp and the Bank are quantitatively and qualitatively restricted under Sections 23A and 23B of the Federal Reserve Act and Federal Reserve Regulation W. Section 23A places restrictions on the Bank's “covered transactions” with Bancorp, including loans and other extensions of credit, investments in the securities of, and purchases of assets from Bancorp. Section 23B requires that certain transactions, including all covered transactions, be on market terms and conditions. Federal Reserve Regulation W combines statutory restrictions on transactions between the Bank and Bancorp with FRB interpretations in an effort to simplify compliance with Sections 23A and 23B.

Capital Requirements

The FRB and the FDIC have adopted risk-based capital guidelines for bank holding companies and banks. Bancorp's ratios exceed the required minimum ratios for capital adequacy purposes and the Bank meets the definition for "well capitalized." Undercapitalized depository institutions may be subject to significant restrictions. Payment of dividends could be restricted or prohibited, with some exceptions, if the Bank were categorized as "critically undercapitalized" under applicable FDIC regulations.

In July 2013, the Federal banking regulators approved a final rule to implement the revised capital adequacy standards of the Basel Committee on Banking Supervision, commonly called Basel III, and to address relevant provisions of the Dodd-Frank Act. The final rule strengthens the definition of regulatory capital, increases risk-based capital requirements, makes selected changes to the calculation of risk-weighted assets, and adjusts the prompt corrective action thresholds. We became subject to the new rule on January 1, 2015 and certain provisions of the new rule will be phased in over the period of 2015 through 2019. We have modeled our ratios under the finalized Basel III rules and we do not expect that we will be required to raise additional capital when the new rules fully phase in. For further information on our risk-based capital positions and the effect of the new Basel III rules, see Note 16 to the Consolidated Financial Statements in Item 8 of this Form 10-K.

The Dodd-Frank Wall Street Reform and Consumer Protection Act

Page-8

On July 21, 2010, President Obama signed into law the Dodd-Frank Act, a landmark financial reform bill comprised of voluminous new rules and restrictions on bank operations as regulations have been promulgated. It includes key provisions aimed at preventing a repeat of the 2008 financial crisis and a new process for winding down failing, systemically important institutions in a manner as close to a controlled bankruptcy as possible. The Dodd-Frank Act includes other key provisions as follows:

(1) Establishes a new Financial Stability Oversight Council to monitor systemic financial risks. The FRB is given extensive new authorities to impose strict controls on large bank holding companies with total consolidated assets equal to or in excess of $50 billion and systemically significant non-bank financial companies to limit the risk they might pose to the economy and other large interconnected companies. The FRB can also take direct control of troubled financial companies that are considered systemically significant.

The Dodd-Frank Act restricts the amount of trust preferred securities (“TruPS”) that may be considered as Tier 1 Capital. For bank holding companies below $15 billion in total assets, TruPS issued before May 19, 2010 are grandfathered, so their status as Tier 1 capital does not change.

(2) Creates a new process to liquidate failed financial firms in an orderly manner, including giving the FDIC broader authority to operate or liquidate a failing financial company.

(3) Establishes a new independent Federal regulatory body for consumer protection within the Federal Reserve System known as the Consumer Financial Protection Bureau ("CFPB"), which assumes responsibility for most consumer protection laws (except the Community Reinvestment Act). It is also in charge of setting appropriate consumer banking fees and caps. The Office of Comptroller of the Currency continues to have authority to preempt state banking and consumer protection laws if these laws "prevent or significantly" interfere with the business of banking.

(4) Places certain limitations on investment and other activities by depository institutions, holding companies and their affiliates, including comprehensive regulation of all over-the-counter derivatives.

(5) Authorizes the FRB to regulate debit card and certain general-use prepaid card transaction interchange fees paid to issuing banks with assets in excess of $10 billion to ensure that fees are “reasonable and proportional” to the cost of processing individual transactions and to prohibit networks and issuers from requiring transactions be processed on a single payment network.

(6) Effects changes in the FDIC assessment as discussed above.

Notice and Approval Requirements Related to Control

Banking laws impose notice, approval and ongoing regulatory requirements on any shareholder or other party that seeks to acquire direct or indirect "control" of an FDIC-insured depository institution. These laws include the BHCA and the Change in Bank Control Act. Among other things, these laws require regulatory filings by a shareholder or other party that seeks to acquire direct or indirect "control" of an FDIC-insured depository institution or bank holding company. The determination whether an investor "controls" a depository institution is based on all of the facts and circumstances surrounding the investment. As a general matter, a party is deemed to control a depository institution or other company if the party owns or controls 25% or more of any class of voting stock. Subject to rebuttal, a party may be presumed to control a depository institution or other company if the investor owns or controls 10% or more of any class of voting stock. Ownership by family members, affiliated parties, or parties acting in concert, is typically aggregated for these purposes. If a party's ownership of the Company were to exceed certain thresholds, the investor could be deemed to "control" the Company for regulatory purposes. This could subject the investor to regulatory filings or other regulatory consequences.

In addition, except under limited circumstances, bank holding companies are prohibited from acquiring, without prior approval:


•	control of any other bank or bank holding company or all or substantially all the assets thereof; or


•	more than 5% of the voting shares of a bank or bank holding company which is not already a subsidiary.

Incentive Compensation

Page-9

The Dodd-Frank Act requires the federal bank regulators and the Securities and Exchange Commission ("SEC") to establish joint regulations or guidelines prohibiting incentive-based payment arrangements at specified regulated entities, including us and our bank, having at least $1 billion in total assets that encourage inappropriate risks by providing an executive officer, employee, director or principal stockholder with excessive compensation, fees, or benefits or that could lead to material financial loss to the entity. In addition, these regulators must establish regulations or guidelines requiring enhanced disclosure to regulators of incentive-based compensation arrangements. The agencies proposed such regulations in April 2011, but the regulations have not been finalized. If the regulations are adopted in the form initially proposed, they will impose limitations on the manner in which we may structure compensation for our executives.

The FRB will review, as part of the regular, risk-focused examination process, the incentive compensation arrangements of banking organizations, such as us, that are not “large, complex banking organizations.” These reviews will be tailored to each organization based on the scope and complexity of the organization’s activities and the prevalence of incentive compensation arrangements. The findings of the supervisory initiatives will be included in reports of examination. Deficiencies will be incorporated into the organization’s supervisory ratings, which can affect the organization’s ability to make acquisitions and take other actions. Enforcement actions may be taken against a banking organization if its incentive compensation arrangements, or related risk management control or governance processes, pose a risk to the organization’s safety and soundness and the organization is not taking prompt and effective measures to correct the deficiencies.

ITEM 1A RISK FACTORS

We assume and manage a certain degree of risk in order to conduct our business. The material risks and uncertainties that Management believes may affect our business are listed below. The list is not exhaustive; additional risks and uncertainties that Management is not aware of, or focused on, or currently deems immaterial may also impair business operations. If any of the following risks, or risks that have not been identified, actually occur, our financial condition, results of operations, and stock trading price could be materially and adversely affected. We manage these risks by promoting sound corporate governance practices, which includes but is not limited to, establishing policies and internal controls, and implementing internal review processes. Before making an investment decision, investors should carefully consider the risks, together with all of the other information included or incorporated by reference in this Annual Report on Form 10-K and our other filings with the SEC. This report is qualified in its entirety by these risk factors.

Earnings are Significantly Influenced by General Business and Economic Conditions

We are subject to changes in general economic conditions that remain uncertain. The economic environment is affected by political uncertainty, changes in fiscal and monetary policy, and uncertainty in the economies of Europe and emerging markets, such as China, which could adversely and materially affect our business. Economic conditions have led to prolonged low interest rates, particularly medium and longer-term rates, which may have a long-term impact on the composition of our earning assets and our net interest margin. Among other things, a period of prolonged lower rates has caused prepayments to increase as our customers sought to refinance existing loans, which resulted in a decrease in the weighted average yield of our earning assets and variability in our net interest income. Furthermore, financial institutions continue to be affected by a stricter regulatory environment. While unemployment rates in our core market areas have continued to improve and are below the average California state rate, there can be no assurance that the recent economic improvement is sustainable or that the creditworthiness of our borrowers will not deteriorate.¹

Weakness in real estate values and home sale volumes, financial stress on borrowers, including job losses, and customers' inability to pay debt could adversely affect our financial condition and results of operations in the following ways:


•	Demand for our products and services may decline;


•	Low cost or non-interest bearing deposits may decrease;


•	Collateral for our loans, especially real estate, may decline in value;


•	Loan delinquencies, problem assets and foreclosures may increase;


•	Investment securities may become impaired.

Interest Rate Risk is Inherent in Our Business

Our earnings and cash flows are largely dependent upon our net interest income. Net interest income is the difference between interest income earned on interest-earning assets, such as loans and securities, and interest expense paid on interest-bearing liabilities, such as deposits and borrowed funds. Interest rates are sensitive to many factors outside of our control, including general economic conditions and the policies of various governmental and regulatory agencies and, in particular, the FRB, which regulates the supply of money and credit in the United States. Changes in monetary policy, including changes in interest rates, can influence not only the interest we receive on loans and securities and interest we pay on deposits and borrowings, but can also affect (i) our ability to originate loans and obtain deposits, (ii) the fair value of our financial assets and liabilities, and (iii) the average duration of our securities and loan portfolios. Our portfolio of securities will generally decline in value if market interest rates increase, and increase in value if market interest rates decline. Our mortgage-backed securities are also subject to prepayment risk when interest rates fall, and subject to borrowers' credit risk when rates rise.

In December 2015, the Federal Open Market Committee of the FRB (“FOMC”) increased the federal funds target rate by 25 basis points (basis points are equal to one hundredth of a percentage point) for the first time in seven years, from a historically low range of 0% to 0.25% to 0.25% to 0.50% currently. However, growing uncertainty about the durability of the U.S. economy's expansion and the Bank of Japan and European Central Bank's recent actions to cut interest rates into negative territory has complicated FOMC's future interest rate planning policy. There was no interest rate action in FOMC's first meeting of 2016 and it is widely expected

____________________________________________________________________________________________

¹Unemployment rates were based on the latest available labor market information from the California Employment Development Department. December 2015 results show that the unemployment rate in Marin County was the lowest in California at 3.2%. The unemployment rates in San Francisco, Sonoma, Napa and Alameda County were 3.3%, 4.2%, 5.1% and 4.3%, respectively, compared to the state of California of 5.8%.

Page-11

that the FOMC will not raise interest rates until they are confident that GDP growth returns to at least 2% from the 0.7% in the fourth quarter of 2015. The FRB's sizable holdings of longer-term securities have placed and will continue to place downward pressure on longer-term interest rates, and hence our net interest margin. Our net interest income is hampered by a flat or falling rate environment, and the prolonged low level of interest rates has resulted in significant net interest margin compression over the last several years. Our 2016 net interest margin may continue to compress due to repricing on loans and securities, if the prevailing market interest rates do not increase.

See the sections captioned “Net Interest Income” in Management's Discussion and Analysis of Financial Condition and Results of Operations in Item 7 and Quantitative and Qualitative Disclosures about Market Risk in Item 7A of this report for further discussion related to management of interest rate risk.

If interest rates rise, we anticipate that net interest income will increase. However, it may take several upward market rate movements for certain variable rate loans to move above their floor rates and deposit behavior may deviate from our expectations. Further, a rise in index rates leads to lower debt service coverage of variable rate loans if the borrower's operating cash flow does not also rise. This creates a paradox of an improving economy (leading to higher interest rates) with increased credit risk as short-term rates move up faster than the cash flow or income of the borrowers. Higher interest rates may also depress loan demand, making it more difficult for us to grow loans.

Banks and Bank Holding Companies are Subject to Extensive Government Regulation and Supervision

Bancorp and the Bank are subject to extensive federal and state governmental supervision, regulation and control. Holding company regulations affect the range of activities in which Bancorp is engaged. Banking regulations affect the Bank's lending practices, capital structure, investment practices and dividend policy, and compliance costs among other things. Future legislative changes or interpretations may also alter the structure and competitive relationship among financial institutions. Legislation is regularly introduced in the U.S. Congress and the California Legislature which could affect our operating environment in substantive ways. The nature and extent of future legislative and regulatory changes affecting us are unpredictable at this time.

The historic disruptions in the financial marketplace during the recent recession have prompted the Obama administration to reform financial market regulation. This reform includes additional regulations over consumer financial products, bond rating agencies and the creation of a regime for regulating systemic risk across all types of financial service firms. Further restrictions on financial service companies may adversely affect our results of operations and financial condition, as well as increase our compliance risk.

Compliance risk is the current and prospective risk to earnings or capital arising from violations of, or non-conformance with, laws, rules, regulations, prescribed practices, internal policies and procedures, or ethical standards set forth by regulators. Compliance risk also arises in situations where the laws or rules governing certain bank products or activities of our clients may be ambiguous or untested. This risk exposes Bancorp and the Bank to potential fines, civil money penalties, payment of damages and the voiding of contracts. Compliance risk can lead to diminished reputation, reduced franchise value, limited business opportunities, reduced expansion potential and an inability to enforce contracts.

For further information on supervision and regulation, see the section captioned “Supervision and Regulation” in Item 1 above.

As discussed in Item 1, Section captioned “Supervision and Regulation” above, in 2010, President Obama signed into law a landmark financial reform bill - the Dodd-Frank Act. The rules under the Dodd-Frank Act change banking statutes and the operating environment of Bancorp and the Bank in substantial and unpredictable ways, and could continue to increase the cost of doing business, decrease our revenues, limit or expand permissible activities or affect the competitive balance depending upon whether or how regulations are implemented. We may continue to invest significant Management attention and resources to make any necessary changes related to the Dodd-Frank Act and any regulations promulgated thereunder.

The broader outcome of the enacted legislation and related measures undertaken to alleviate the aftermaths of the credit crisis is uncertain. The capital and credit markets experienced volatility and disruption at unprecedented levels in the last credit crisis. In some cases, the markets have produced downward pressure on credit availability for certain

Page-12

issuers without regard to those issuers' underlying financial strength. If similar disruptions and volatility return, there can be no assurance that we will not experience an adverse effect on our ability to access credit or capital.

Intense Competition with Other Financial Institutions to Attract and Retain Banking Customers

We are facing significant competition for customers from other banks and financial institutions located in the markets that we serve. We compete with commercial banks, saving banks, credit unions, non-bank financial services companies and other financial institutions operating within or near our service areas. Some of our non-bank competitors and peer-to-peer lenders may not be subject to the same extensive regulations as we are, giving them greater flexibility in competing for business. We anticipate intense competition will continue for the coming year due to the consolidation of many financial institutions and more changes in legislature, regulation and technology. National and regional banks much larger than our size have entered into our market through acquisitions and they may be able to benefit from economies of scale through their wider branch networks, more prominent national advertising campaigns, lower cost of borrowing, capital market access and sophisticated technology infrastructures. Further, intense competition for creditworthy borrowers could lead to loan rate concession pressure or affect our ability to generate profitable loans.

Going forward, we may see continued competition in the industry as competitors seek to expand market share in more profitable and less risky customer segments. Further, if equity markets rebound, our deposit customers may perceive alternative investment opportunities as providing superior expected returns. Recent recovery in the real estate market also supports the sale of real estate that collateralizes our loans, leading to payoff activity. Technology and other changes have made it more convenient for bank customers to transfer funds into alternative investments or other deposit accounts such as online virtual banks and non-bank service providers. Efforts and initiatives we may undertake to retain and increase deposits, including deposit pricing, can increase our costs. When our customers move money into higher yielding deposits or alternative investments, we may lose a relatively inexpensive source of funds, thus increasing our funding costs through more expensive wholesale borrowings.

Negative Conditions Affecting Real Estate May Harm Our Business

Concentration of our lending activities in the California real estate sector could negatively affect our results of operations if adverse changes in our lending area occur or intensify. Although we do not offer traditional first mortgages, nor have sub-prime or Alt-A residential loans or significant amounts of securities backed by such loans in the portfolio, we are not immune to volatility in those markets. Approximately 85% of our loans were secured by real estate at December 31, 2015, of which 66% were secured by commercial real estate and the remaining 19% by residential real estate. Real estate valuations are influenced by demand, and demand is driven by factors such as employment rates and interest rates.

Loans secured by commercial real estate include those secured by office buildings, owner-user office/warehouses, mixed-use residential/commercial properties and retail properties. In general, 2015 office, industrial and retail vacancy rates remained largely unchanged in Marin County, fell in Sonoma County and increased slightly in Napa County based on the latest available real estate information from Keegan & Coppin Company, Inc. There can be no assurance that the companies or properties securing our loans will generate sufficient cash flows to allow borrowers to make full and timely loan payments to us. In the event of default, the collateral value may not cover the outstanding amount due to us, especially during real estate market downturns.

Rising commercial real estate lending concentrations may expose institutions to unanticipated earnings and capital volatility in the event of adverse changes in the investor commercial real estate market. Institutions that are potentially exposed to significant commercial real estate concentration risk may be subject to increased regulatory scrutiny. Institutions that have experienced rapid growth in commercial real estate lending such as us, have notable exposure to a specific type of commercial real estate lending, or are approaching or exceed certain supervisory criteria that measure an institution's commercial real estate portfolio against its capital levels, may be subject to such increased regulatory scrutiny. We maintain heightened review and analyses of our concentrations and have regular conversations with regulators to avoid unexpected regulatory risk.

Severe Weather, Natural Disasters or Other Climate Change Related Matters Could Significantly Affect Our Business

Our primary market is located in an earthquake-prone zone in northern California, which is also subject to other weather or disasters, such as severe rainstorms, wildfire, drought or flood. These events could interrupt our business operations

Page-13

unexpectedly. Climate-related physical changes and hazards could also pose credit risks for us. For example, our borrowers may have collateral properties or operations located in coastal areas at risk to a rise in sea level or affected by the severe drought in California. The properties pledged as collateral on our loan portfolio could also be damaged by tsunamis, floods, earthquakes or wildfires and thereby the recoverability of loans could be impaired. A number of factors can affect credit losses, including the extent of damage to the collateral, the extent of damage not covered by insurance, the extent to which unemployment and other economic conditions caused by the natural disaster adversely affect the ability of borrowers to repay their loans, and the cost of collection and foreclosure to us. Lastly, there could be increased insurance premiums and deductibles, or a decrease in the availability of coverage, due to severe weather-related losses. The ultimate outcome on our business of a natural disaster, whether or not caused by climate change, is difficult to predict.

We are Subject to Significant Credit Risk and Loan Losses May Exceed Our Allowance for Loan Losses in the Future

We maintain an allowance for loan losses, which is a reserve established through provisions for loan losses charged to expense, that represents Management's best estimate of probable losses that may be incurred within the existing portfolio of loans (the "incurred loss model"). The level of the allowance reflects Management's continuing evaluation of industry concentrations, specific credit risks, loan loss experience, current loan portfolio quality and present economic, political and regulatory conditions. The determination of the appropriate level of the allowance for loan losses inherently involves a high degree of subjectivity and requires us to make significant estimates of current credit risks and future trends, all of which may undergo material changes. Further, we generally rely on appraisals of the collateral or comparable sales data to determine the level of specific reserve and/or the charge-off amount on certain collateral dependent loans. Inaccurate assumptions in the appraisals or an inappropriate choice of the valuation techniques may lead to an inadequate level of specific reserve or charge-offs.

Changes in economic conditions affecting borrowers, new information regarding existing loans and their collateral, identification of additional problem loans, and other factors may require an increase in our allowance for loan losses. In addition, bank regulatory agencies periodically review our allowance for loan losses and may require an increase in the provision for loan losses or the recognition of further loan charge-offs. If charge-offs in future periods exceed the allowance for loan losses or cash flows from acquired loans do not perform as expected, we will need to record additional provision for loan losses.

In December 2012, the Financial Accounting Standards Board (“FASB”) issued a proposed Accounting Standards Update, Financial Instruments: Credit Losses, which establishes a new impairment framework also known as the "current expected credit loss model." In contrast to the incurred loss model currently used by financial entities like Bancorp, the current expected credit loss model requires an allowance be recognized based on the expected credit losses (i.e. all contractual cash flows that the entity does not expect to collect from financial assets or commitments to extend credit). It requires the consideration of more forward-looking information than is permitted under current U.S. generally accepted accounting principles. In addition to relevant information about past events and current conditions, such as borrowers’ current creditworthiness, quantitative and qualitative factors specific to borrowers, and the economic environment in which the entity operates, the new model requires consideration of reasonable and supportable forecasts that affect the expected collectability of the financial assets’ remaining contractual cash flows, and evaluation of the forecasted direction of the economic cycle, as well as time value of money. This proposed impairment framework is expected to have wide reaching implications to financial institutions. The allowance for loan losses may increase due to a larger volume of financial assets that fall within the scope of the proposed model, which may adversely affect earnings and lead to higher capital requirements. The FASB continued to deliberate the proposed update at its December 31, 2015 meeting, and the full effect of the implementation of this new model is unknown until the proposed guidance is finalized.

Non-performing Assets Take Significant Time to Resolve and Adversely Affect Results of Operations and Financial Condition.

While we have significantly reduced non-performing assets, such assets may adversely affect our net income in the future. We might incur losses relating to non-performing assets if their collateral values deteriorate. Historically, we have not recorded interest income on non-accrual loans, which adversely affects our interest income and increases our loan administration costs. When we take collateral in foreclosures and similar proceedings, we are required to mark the related loan to the fair value of the collateral, which may result in a loss. While we have managed our problem

Page-14

assets through workouts, restructurings and other proactive credit management, decreases in the value of the assets, underlying collateral, or borrowers' performance or financial conditions, whether or not due to economic and market conditions beyond our control, could adversely affect our business, results of operations and financial condition. In addition, the resolution of non-performing assets can distract Management from other responsibilities. There can be no assurance that we will not experience further increases in non-performing assets in the future.

Securities May Lose Value due to Credit Quality of the Issuers

We invest in debentures issued by government-sponsored enterprises ("GSE"), such as Federal Home Loan Bank ("FHLB"), Federal National Mortgage Association (“FNMA”), Federal Home Loan Mortgage Corporation ("FHLMC"), and Federal Farm Credit Bank. While we consider them to have low credit risk as they carry the implicit backing of the U.S. Government, they are not direct obligations of the U.S. Government. GSE debt is sponsored but not guaranteed by the federal government, whereas government agencies such as Government National Mortgage Association ("GNMA") are divisions of the government whose securities are backed by the full faith and credit of the United States.

We also hold mortgage-backed securities (“MBS”) securities issued by FNMA and FHLMC. Since 2008, both FNMA and FHLMC have been under a U.S. Government conservatorship. As a result, the mortgage-backed securities (“MBS”) issued by FNMA and FHLMC have benefited from this government support. However, there are political pressures to phase out the governmental support via privatization or to wind down FNMA and FHLMC and uncertainty as to the termination of conservatorship of FNMA and FHLMC remains.

The fair value of our securities issued or guaranteed by these entities may decline when the U.S. Government starts selling FNMA and FHLMC MBS, when the government support is phased-out or completely withdrawn, or if either FNMA or FHLMC comes under further financial stress or suffers creditworthiness deterioration.

We also invest in obligations of state and political subdivisions, some of which may not have fully recovered from past years' of loss of property tax from falling home values and declines in sales tax revenues. While we generally seek to minimize our exposure by diversifying the geographic location of our portfolio and investing in investment grade securities, there is no guarantee that the issuers will remain financially sound or continue their payments on these debentures.

Unexpected Early Termination of Interest Rate Swap Agreements May Affect Earnings

We have entered into interest-rate swap agreements, primarily as an asset/liability risk management tool, in order to mitigate the changes in the fair value of specified long-term fixed-rate loans and firm commitments to enter into long-term fixed-rate loans caused by changes in interest rates. These hedges allow us to offer long-term, fixed-rate loans to customers without assuming the interest rate risk of a long-term asset by swapping our fixed-rate interest stream for a floating-rate interest stream. In the event of default by the borrowers on our hedged loans, we may have to terminate these designated interest-rate swap agreements early, resulting in prepayment penalties charged by our counterparties and negatively affect our earnings.

Growth Strategy or Potential Future Acquisitions May Produce Unfavorable Outcomes

We seek to expand our franchise safely and consistently. A successful growth strategy requires us to manage multiple aspects of the business simultaneously, such as following adequate loan underwriting standards, balancing loan and deposit growth without increasing interest rate risk or compressing our net interest margin, maintaining sufficient capital, and recruiting, training and retaining qualified professionals.

Our growth strategic plan also includes merger and acquisition possibilities that either enhance our market presence or have potential for improved profitability through financial management, economies of scale or expanded services. We may incur significant acquisition related expenses either during the due diligence phase of acquisition targets or during integration of the acquirees. These expenses may negatively impact our earnings prior to realizing the benefits of acquisitions. We may also be exposed to difficulties in combining the operations of acquired institutions into our own operations, which may prevent us from achieving the expected benefits from our acquisition activities. Our earnings, financial condition and prospects after a merger will depend in part on our ability to integrate the operations and management of the acquired institution while continuing to implement other aspects of our business plan. Inherent uncertainties exist in integrating the operations of an acquired institution and there is no assurance that we will be able to do so successfully. Among the issues that we could face are:

Page-15


•	unexpected problems with operations, personnel, technology or credit;


•	loss of customers and employees of the acquiree;


•	difficulty in working with the acquiree's employees and customers;


•	the assimilation of the acquiree's operations, culture and personnel;


•	instituting and maintaining uniform standards, controls, procedures and policies; and


•	litigation risk not discovered during the due diligence period.

Undiscovered factors as a result of an acquisition could bring liabilities against us, our management and the management of the institutions we acquire. These factors could contribute to our not achieving the expected benefits from our acquisitions within desired time frames, if at all. Further, although we generally anticipate cost savings from acquisitions, we may not be able to fully realize those savings. Any cost savings that are realized may be offset by losses in revenues or other charges to earnings.

We May Not Be Able to Attract and Retain Key Employees

Our success depends, in large part, on our ability to attract and retain key people. Competition for the best people in most activities engaged by us has been intense, especially in light of the recent improvement in the job market, and we may not be able to hire skilled people or retain them. We do not have non-compete agreements with any of our senior officers. The unexpected loss of key personnel could have an unfavorable affect on our business because of the skills, knowledge of our market, years of industry experience and difficulty of promptly finding qualified replacement personnel.

Accounting Estimates and Risk Management Processes Rely on Analytical and Forecasting Models

The processes we use to estimate probable loan losses and to measure the fair value of financial instruments, as well as the processes used to estimate the effects of changing interest rates and other market measures on our financial condition and results of operations, depends upon the use of analytical and forecasting models. These models reflect assumptions that may not be accurate, particularly in times of market stress or other unforeseen circumstances. Even if these assumptions are adequate, the models may prove to be inadequate or inaccurate because of other flaws in their design or their implementation. If the models we use for interest rate risk and asset-liability management are inadequate, we may incur increased or unexpected losses upon changes in market interest rates or other market measures. If the models we use for determining our probable loan losses are inadequate, the allowance for loan losses may not be sufficient to support future charge-offs. If the models we use to measure the fair value of financial instruments are inadequate, the fair value of such financial instruments may fluctuate unexpectedly or may not accurately reflect what we could realize upon sale or settlement of such financial instruments. Any such failure in our analytical or forecasting models could have a material adverse effect on our business, financial condition and results of operations.

The Value of Goodwill and Other Intangible Assets May Decline in the Future

As of December 31, 2015, we had goodwill totaling $6.4 million and a core deposit intangible asset totaling $3.1 million from the NorCal acquisition (the “NorCal Acquisition”). A significant decline in expected future cash flows, a significant adverse change in the business climate, slower growth rates or a significant and sustained decline in the price of our common stock could necessitate taking charges in the future related to the impairment of goodwill or other intangible assets. If we were to conclude that a future write-down of goodwill or other intangible assets is necessary, we would record the appropriate charge, which could have a material adverse effect on our business, financial condition and results of operations.

We May Take Filing Positions or Follow Tax Strategies That May Be Subject to Challenge

We provide for current and deferred taxes in our consolidated financial statements based on our results of operations, business activities and business combinations, legal structure and federal and state legislation and regulations. We may take filing positions or follow tax strategies that are subject to interpretation of tax statutes. Our net income may be reduced if a federal, state or local authority were to assess charges for taxes that have not been provided for in our consolidated financial statements. Taxing authorities could change applicable tax laws, challenge filing positions or assess new taxes and interest charges. If taxing authorities take any of these actions, our business, results of operations or financial condition could be adversely and significantly affected.

Page-16

Financial Institutions Rely on Technology and Continually Encounter Technological Change

The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services. The effective use of technology will enable efficiency and meet customers' changing needs. Our future success depends, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands, as well as to create additional efficiencies in our operations. Failure to keep pace with technological change affecting the financial services industry could have a material adverse impact on the long-term success of our business and, in turn, our financial condition and results of operations.

Risks Associated with Cyber Security Could Negatively Affect Our Earnings and Reputation

Our business requires the secure e-management of sensitive client and bank information. We work diligently through implementing security measures that make our communications and information systems safe to conduct business. Cyber threats such as social engineering, ransomware, and phishing emails are more prevalent now than ever before. These incidents include intentional and unintentional events that may present threats to digital systems that are designed to disrupt operations, corrupt data, release sensitive information or cause denial-of-service attacks. A cyber security breach of systems operated by the Bank, merchants, vendors, customers, or externally publicized breaches of other financial institutions may significantly harm our reputation, result in a loss of customer business, subject us to regulatory scrutiny, or expose us to civil litigation and financial liability. While we have systems and procedures designed to prevent security breaches, we cannot be certain that advances in criminal capabilities, physical system or network break-ins or inappropriate access will not compromise or breach the technology protecting our networks or proprietary client information.

We Rely on Third-Party Vendors for Important Aspects of Our Operation

We depend on the accuracy and completeness of information and systems provided by certain key vendors, including but not limited to data processing, payroll processing, technology support, investment safekeeping and accounting. In particular, we outsource core processing to Fidelity Information Services ("FIS"), a leading financial services solution provider, which allows us access to competitive technology offerings without having to directly invest in their development. Our ability to operate, as well as our financial condition and results of operations, could be negatively affected in the event of an interruption of an information system, an undetected error, a cyber breach, or in the event of a natural disaster whereby certain vendors are unable to maintain business continuity.

Failure of Correspondent Banks and Counterparties May Affect Liquidity

In the economic downturn, the financial services industry in general was materially and adversely affected by the credit crisis. We have witnessed failures and consolidations of banks in the industry in recent years. We rely on our correspondent banks for lines of credit, which can be revoked unexpectedly. We also have two correspondent banks as counterparties in our derivative transactions (see Note 15 to the Consolidated Financial Statements in item 8 in this Form 10-K). While we regularly monitor the financial health of our correspondent banks and we have diverse sources of liquidity, should any one of our correspondent banks become financially impaired, our available credit may decline and/or they may be unable to honor their commitments.

Deterioration of Credit Quality or Insolvency of Insurance Companies May Impede Our Ability to Recover Losses

The financial crisis led certain major insurance companies to be downgraded by rating agencies. We have property, casualty and financial institution risk coverage underwritten by several insurance companies, who may not avoid insolvency risk inherent in the insurance industry. In addition, some of our investments in obligations of state and political subdivisions are insured by insurance companies. While we closely monitor the credit ratings of our insurers and the insurers of our municipal securities and we are poised to make quick changes if needed, we cannot predict an unexpected inability to honor commitments. We also invest in bank-owned life insurance policies on certain members of Management, which may lose value in the event of a carrier's insolvency. In the event that a bank-owned life insurance policy carrier's credit ratings fall below investment grade, we may exchange policies to other carriers at a cost charged by the original carrier, or we may terminate the policies which may result in adverse tax consequences.

Page-17

Our loan portfolio is secured primarily by properties located in earthquake or fire-prone zones. In the event of a disaster that causes pervasive damage to the region in which we operate, not only the Bank, but also the loan collateral may suffer losses not recoverable by insurance.

Bancorp Relies on Dividends from the Bank to Pay Cash Dividends to Shareholders

Bancorp is a separate legal entity from its subsidiary, the Bank. Bancorp receives substantially all of its revenue from the Bank in the form of dividends, which is Bancorp's principal source of funds to pay cash dividends to Bancorp's common shareholders, service subordinated debt, and cover operational expenses of the holding company. Various federal and state laws and regulations limit the amount of dividends that the Bank may pay to Bancorp. In the event that the Bank is unable to pay dividends to Bancorp, Bancorp may not be able to pay dividends to its shareholders or pay interest on the subordinated debentures. As a result, it could have an adverse effect on Bancorp's stock price and investment value.

Under federal law, capital distributions from the Bank would become prohibited, with limited exceptions, if the Bank were categorized as "undercapitalized" under applicable FRB or FDIC regulations. In addition, as a California bank, Bank of Marin is subject to state law restrictions on the payment of dividends. For further information on the distribution limit from the Bank to Bancorp, see the section captioned “Bank Regulation” in Item 1 above and “Dividends” in Note 9 to the Consolidated Financial Statements in Item 8 of this report.

The Trading Volume of Bancorp's Common Stock is Less than That of Other, Larger Financial Services Companies

Our common stock is listed on the NASDAQ Capital Market exchange. Our trading volume is less than that of nationwide or larger regional financial institutions. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence of willing buyers and sellers of common stock at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which we have no control. Given the low trading volume of our common stock, significant trades of our stock in a given time, or the expectations of these trades, could cause volatility in the stock price.

We may need to Raise Additional Capital in the Future, and if we Fail to Maintain Sufficient Capital, Whether due to Losses, an Inability to Raise Additional Capital or Otherwise, our Financial Condition, Liquidity and Results of Operations, as well as our Ability to Maintain Regulatory Compliance, Could be Adversely Affected

We face significant capital and other regulatory requirements as a financial institution. We may need to raise additional capital in the future to provide us with sufficient capital resources and liquidity to meet our commitments and business needs, which could include the possibility of financing acquisitions. In addition, Bancorp, on a consolidated basis, and the Bank, on a stand-alone basis, must meet certain regulatory capital requirements and maintain sufficient liquidity. Importantly, as discussed below, regulatory capital requirements could increase from current levels, which could require us to raise additional capital or contract our operations. Our ability to raise additional capital depends on conditions in the capital markets, economic conditions and a number of other factors, including investor perceptions regarding the banking industry, market conditions and governmental activities, and on our financial condition and performance. Accordingly, we cannot assure that we will be able to raise additional capital if needed or on terms acceptable to us. If we fail to maintain capital to meet regulatory requirements, our liquidity, business, financial condition and results of operations could be materially and adversely affected.

We may be Subject to more Stringent Capital Requirements in the Future

We are subject to regulatory requirements specifying minimum amounts and types of capital that we must maintain. From time to time, the regulators change these regulatory capital adequacy guidelines. If we fail to meet these minimum capital guidelines and other regulatory requirements, Bancorp or the Bank may be restricted in the types of activities we may conduct and we may be prohibited from taking certain capital actions, such as paying dividends and repurchasing or redeeming capital securities.

In particular, the capital requirements applicable to us under the recently adopted capital rules implementing the Basel III capital framework in the United States began to be phased-in on January 1, 2015. As these new rules take effect,

Page-18

we will be required to satisfy additional, more stringent, capital adequacy standards than we have in the past. In addition, if we become subject to annual stress testing requirements, our stress test results may have the effect of requiring us to comply with even greater capital requirements. While we currently meet the requirements of the new Basel III-based capital rules on a fully implemented basis, we may eventually fail to do so. In addition, these requirements could have a negative affect on our ability to lend, grow deposit balances, make acquisitions or make capital distributions in the form of dividends or share repurchases. Higher capital levels could also lower our return on equity.

We may be Subject to Environmental Liabilities in Connection with the Foreclosure on Real Estate Assets Securing our Loan Portfolio

Hazardous or toxic substances or other environmental hazards may be located on the properties that secure our loans. If we acquire such properties as a result of foreclosure or otherwise, we could become subject to various environmental liabilities. For example, we could be held liable for the cost of cleaning up or otherwise addressing contamination at or from these properties. We could also be held liable to a governmental entity or third-party for property damage, personal injury or other claims relating to any environmental contamination at or from these properties. In addition, we own and operate certain properties that may be subject to similar environmental liability risks. Although we have policies and procedures that are designed to mitigate against certain environmental risks, we may not detect all environmental hazards associated with these properties. If we ever became subject to significant environmental liabilities, our business, financial condition and results of operations could be adversely affected.

The Small to Medium-sized Businesses that we Lend to may have Fewer Resources to Weather Adverse Business Developments, which may Impair a Borrower's Ability to Repay a Loan, and such Impairment could Adversely Affect our Results of Operations and Financial Condition

We focus our business development and marketing strategy primarily on small to medium-sized businesses. Small to medium-sized businesses frequently have smaller market shares than their competition, may be more vulnerable to economic downturns, often need substantial additional capital to expand or compete and may experience substantial volatility in operating results, any of which may impair a borrower's ability to repay a loan. In addition, the success of a small and medium-sized business often depends on the management talents and efforts of one or two people or a small group of people, and the death, disability or resignation of one or more of these people could adversely affect the business and its ability to repay its loan. If general economic conditions negatively affect the California markets in which we operate and small to medium-sized businesses are adversely affected or our borrowers are otherwise affected by adverse business developments, our business, financial condition and results of operations may be negatively affected.

A Lack of Liquidity could Adversely Affect our Operations and Jeopardize our Business, Financial Condition and Results of Operations

Liquidity is essential to our business. We rely on our ability to generate deposits and effectively manage the repayment and maturity schedules of our loans and investment securities, respectively, to ensure that we have adequate liquidity to fund our operations. An inability to raise funds through deposits, borrowings, the sale of investment securities, Federal Home Loan Bank advances, the sale of loans and other sources could have a substantial negative effect on our liquidity. Our most important source of funds consists of deposits. Deposit balances can decrease when customers perceive alternative investments as providing a better risk/return tradeoff. If customers move money out of bank deposits and into other investments, we would lose a relatively low-cost source of funds, increasing our funding costs and reducing our net interest income and net income.

Other primary sources of funds consist of cash flows from operations, investment maturities and sales of investment securities and proceeds from the issuance and sale of any equity and debt securities to investors. Additional liquidity is provided by the ability to borrow from the Federal Reserve Bank of San Francisco and the Federal Home Loan Bank and our ability to raise brokered deposits. We also may borrow funds from third-party lenders, such as other financial institutions. Our access to funding sources in amounts adequate to finance or capitalize our activities, or on terms that are acceptable to us, could be impaired by factors that affect us directly or the bank or non-bank financial services industries or the economy in general, such as disruptions in the financial markets or negative views and expectations about the prospects for the bank or non-bank financial services industries.

Page-19

Based on past experience, we believe that our deposit accounts are relatively stable sources of funds. If we increase interest rates paid to retain deposits, our earnings may be adversely affected, which could have an adverse effect on our business, financial condition and results of operations.

Any decline in available funding could adversely affect our ability to originate loans, invest in securities, meet our expenses, pay dividends to our shareholders or to fulfill obligations such as repaying our borrowings or meeting deposit withdrawal demands, any of which could have a material adverse impact on our liquidity, business, financial condition and results of operations.

Five-Year Stock Price Performance Graph

The following graph, compiled by SNL Financial LC of Charlottesville, Virginia, shows a comparison of cumulative total shareholder return on our common stock during the five fiscal years ended December 31, 2015 compared to the Russell 2000 Stock index and the SNL Bank $1B - $5B Index. The comparison assumes $100 was invested on December 31, 2010 in our common stock and all of the dividends were reinvested. The graph represents past performance and should not be considered to be an indication of future performance. In addition, total return performance results vary depending on the length of the performance period.

The Company's Annual Report on Form 10-K for the year ended December 31, 2014 included the total return performance of stock prices of a group of twenty public California peer bank issuers with assets ranging from $1 billion to $5 billion compiled by an investment banking company. Management believes that a better comparison is provided by the SNL Bank $1B to $5B index, which is a published industry index that includes a larger pool of peer banks comparable to us. The following graph excludes the California peer issuers as the banks that could be included in the group are limited and have been affected by mergers and changes in asset size.

ITEM 7 MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of financial condition as of December 31, 2015 and 2014 and results of operations for each of the years in the three-year period ended December 31, 2015 should be read in conjunction with our consolidated financial statements and related notes thereto, included in Part II Item 8 of this report. Average balances, including balances used in calculating certain financial ratios, are generally comprised of average daily balances.

Forward-Looking Statements

The disclosures set forth in this item are qualified by important factors detailed in Part I captioned Forward-Looking Statements and Item 1A captioned Risk Factors of this report and other cautionary statements set forth elsewhere in the report.

Executive Summary

Earnings in 2015 totaled $18.4 million compared to earnings of $19.8 million in 2014. Diluted earnings of $3.04 per share for the year ended December 31, 2015 compared to $3.29 per share in the same period of 2014. Return on assets ("ROA") was 0.98% in 2015 compared to 1.08% in 2014. Return on equity ("ROE") was 8.84% in 2015 compared to 10.31% in 2014.

The following are highlights of our operating and financial performance for the year ended December 31, 2015:


•	The Bank generated record loan originations of $252 million in 2015, offset by payoffs for a net increase of $88 million from last year.


•	Credit quality remains strong with non-accrual loans trending downward, representing 0.15% of total loans at year end.


•	Total deposits grew 11.4% year-over-year to $1.73 billion from $1.55 billion.


•	Our loan to deposit ratio has increased to 84%.


•	All of our capital ratios are well above current regulatory requirements for a "well-capitalized" institution. Total risk-based capital ratio for Bancorp was 13.4% at December 31, 2015.


•	Reflecting the strength of the Bank and its future prospects, the Board of Directors declared the 43rd consecutive quarterly cash dividend in January 2016. The dividend increased $0.01 from the prior quarter and $0.03, or 14% from one year ago to $0.25 per share.

Net interest income totaled $67.2 million and $70.4 million in 2015 and 2014, respectively. The tax-equivalent net interest margin was 3.83% in 2015 compared to 4.13% in 2014. The decrease in net interest margin relates to the continued effect of the low interest rate environment on our loan and investment portfolio turnover and a decline in accretion income related to acquired loans purchased at a discount.

Non-interest income totaled $9.2 million in 2015 compared to $9.0 million in the same period of 2014, an increase of $152 thousand, or 1.7%. The increase in 2015 compared to 2014 primarily relates to higher dividend income from the Federal Home Loan Bank of San Francisco, partially offset by lower merchant interchange fees due to decreased transaction volume.

Non-interest expense totaled $46.9 million and $47.3 million in 2015 and 2014, respectively, a decrease of $314 thousand, or 0.7%. The decrease in non-interest expense from the prior year is primarily due to the reversal of provision for losses on off-balance sheet commitments and a decrease in data processing expense as the first quarter of 2014 included $442 thousand in one-time NorCal Acquisition-related expenses. Decreases were partially offset by higher salaries and benefits and higher occupancy expense relating to non-recurring accounting adjustments in 2015. Our e

Page-24

fficiency ratio (the ratio of non-interest expense divided by the sum of net interest income and non-interest income) was 61.47%, 59.46% and 65.97% in 2015, 2014 and 2013, respectively. Our expense discipline allowed for a healthy efficiency ratio, notwithstanding the challenging interest rate, competitive and regulatory environments.

Gross loans increased to $1,451.2 million at December 31, 2015 compared to $1,363.4 million at December 31, 2014, which was driven substantially by new loan volume in investor commercial real estate and commercial and industrial (and related owner occupied commercial real estate). Loan growth in 2015 totaled $87.8 million, or 6.5% over 2014, and was the result of strong new loan volume partially offset by high payoffs.

Credit quality is very strong and continues to improve. Non-accrual loans continued to trend downward, and decreased to $2.2 million at December 31, 2015 from $9.4 million at December 31, 2014, and as a percentage of total loans declined to 0.15% from 0.69% a year ago. The decrease in non-accrual loans from the prior year primarily relates to a previously non-performing loan that was returned to accrual status, the payoff of a commercial real estate loan, and a land development loan that was sold. Net charge-offs for the year ended December 31, 2015 totaled $600 thousand compared to net recoveries of $124 thousand in the prior year. The charge-offs during 2015 primarily related to the land development loan sale.

The provision for loan losses totaled $500 thousand in 2015, compared to $750 thousand in the prior year. The ratio of loan loss reserve to loans decreased from 1.11% at December 31, 2014 to 1.03% at December 31, 2015. The decrease compared to the prior year is primarily related to the improvement in credit quality.

Deposits totaled $1,728.2 million at December 31, 2015 compared to $1,551.6 million at December 31, 2014. Total deposits increased $176.6 million, or 11.4%, compared to December 31, 2014. Non-interest bearing deposits totaled $770.1 million at December 31, 2015, an increase of $99.2 million, or 14.8%, when compared to December 31, 2014. Non-interest bearing deposits represented 44.6% of total deposits as of December 31, 2015 compared to 43.2% at December 31, 2014. The increase in deposits resulted from existing relationships and the development of a number of new relationships.

The total risk-based capital ratio for Bancorp was 13.4% at December 31, 2015 compared to 13.9% at December 31, 2014. The decrease primarily resulted from an increase in risk-weighted assets due to higher loan and investment balances. All risk-based capital ratios continue to be well above (i) regulatory requirements and the new Basel III requirements that took effect on January 1, 2015 (Basel Committee on Bank Supervision guidelines for determining regulatory capital) and (ii) the new Basel III requirements on a fully phased-in basis.

In summary, 2015 was a good year reflecting our consistent approach to the way we do business. Our discipline brought us through the recession in solid financial condition and should ensure our continued success and profitable growth.

The following factors may impact the Company’s performance in 2016:


•	New lending and deposit relationships in 2015 should benefit us for a full year in 2016.


•	We have ample liquidity and capital to support continued growth in coming years.


•	Acquisitions remain a component of our strategic plan. The Bay Area is the most attractive area in the country and we intend to expand our footprint through organic growth and strategic acquisitions.


•	Expense control continues to be a critical component of our success. We are convinced that great efficiencies can be achieved as we grow as an organization serving the Bay Area.


•	Our net interest margin in 2016 may continue to compress if the current market interest rates do not increase.

Critical Accounting Policies and Estimates

Critical accounting policies are those that are both very important to the portrayal of our financial condition and results of operations and require Management's most difficult, subjective, or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and imprecise.

Management has determined the following four accounting policies to be critical:

Allowance for Loan Losses: For information regarding our ALLL methodology, the related provision for loan losses, risks related to asset quality and lending activity, see Item 1A - Risk Factors, Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations, and Note 1 - Summary of Significant Accounting Policies and Note 4 - Loans and Allowance for Loan Losses in Item 8 - Financial Statements and Supplementary Data of this Form 10-K.

Other-than-temporary Impairment of Investment Securities: For information regarding our investment securities, investment activity, and related risks, see Item 1A - Risk Factors, Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations, and Note 1 - Summary of Significant Accounting Policies and Note 3 - Investment Securities in Item 8 - Financial Statements and Supplementary Data of this Form 10-K.

Accounting for Income Taxes: For information on our tax assets and liabilities, and related provision for income taxes, see Note 1 - Summary of Significant Accounting Policies and Note 12 - Income Taxes in Item 8 - Financial Statements and Supplementary Data of this Form 10-K.

Fair Value Measurements: For information on our use of fair value measurements and our related valuation methodologies, see Note 1 - Summary of Significant Accounting Policies and Note 10 - Fair Value of Assets and Liabilities in Item 8 - Financial Statements and Supplementary Data of this Form 10-K.

RESULTS OF OPERATIONS

Net Interest Income

Net interest income is the difference between the interest earned on loans, investments and other interest-earning assets and the interest expense incurred on deposits and other interest-bearing liabilities. Net interest income is affected by changes in general market interest rates and by changes in the amounts and composition of interest-earning assets and interest-bearing liabilities. 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. We manage interest rate risk exposure with the goal of minimizing the effect of interest rate volatility on net interest margin.

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.

The following table, Average Statements of Condition and Analysis of Net Interest Income, compares interest income and average interest-earning assets with interest expense and average interest-bearing liabilities for the periods presented. The table also indicates net interest income, net interest margin and net interest rate spread for each period presented.

¹Interest income/expense is divided by actual number of days in the period times 360 days to correspond to stated interest rate terms, where applicable.
² Yields on available-for-sale securities are calculated based on amortized cost balances rather than fair value, as changes in fair value are reflected as a component of stockholders' equity. Investment security interest is earned on 30/360 basis monthly.
³ Yields and interest income on tax-exempt securities and loans are presented on a taxable-equivalent basis using the Federal statutory rate of 35%.
⁴ Average balances on loans outstanding include non-accrual loans. The amortized portion of net loan origination fees is included in interest income on loans, representing an adjustment to the yield.

2015 compared with 2014:

The tax-equivalent net interest margin was 3.83% in 2015, compared to 4.13% in 2014. The decrease of thirty basis points was primarily due to a lower yield on interest-earning assets, mainly relating to a decrease in accretion and gains on payoffs of acquired loans, new loans and investment securities yielding lower rates and downward repricing on renewed loans. The net interest spread decreased twenty nine basis points over the same period for the same reasons.

The yield on average interest-earning assets decreased thirty basis points in 2015 compared to 2014 for the reasons listed above. The loan portfolio as a percentage of average interest-earning assets, decreased to 76.2% in 2015, from 76.5% in 2014. The investment securities were 20.9% and 19.8% of average interest-earning assets in 2015 and 2014, respectively. Total average interest-earning assets increased $54.6 million, or 3.2%, in 2015 compared to 2014.

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) regulated by the FOMC. In December 2015, the FOMC raised the target federal funds rate by 25 basis points to a range of 0.25% to 0.50%. This increase from the historic low of 0.00% to 0.25% had not changed for the past seven years. The prolonged low interest rate environment has negatively affected our net interest margin and yields on our earning assets and resulted in significant net interest margin compression over the last several years. Our net interest margin in 2016 may continue to compress if the current market interest rates do not increase.

Page-27

Early payoffs or prepayments of our acquired loans with significant unamortized purchase discount/premium could result in volatility in our net interest margin. Accretions and gains on payoffs of purchased loans recorded to interest income and the affect on our net interest margin during the past three years were as follows:

2014 Compared with 2013:

The tax-equivalent net interest margin was 4.13% in 2014, compared to 4.20% in 2013. The decrease of seven basis points was primarily due to a lower yield on interest-earning assets, mainly relating to new loans yielding lower rates and downward repricing on renewed loans offset by an increase in accretion and gains on payoffs of acquired loans. In addition to the decrease on lower yielding interest-earning assets, the cost of interest-bearing liabilities increased by four basis points in 2014 due to subordinated debt acquired, compared to 2013. The net interest spread decreased ten basis points over the same period for the same reasons.

The average yield on interest-earning assets decreased six basis points in 2014 compared to 2013 due to the reasons listed above. The loan portfolio as a percentage of average interest-earning assets, decreased to 76.5% in 2014, from 77.3% in 2013. The investment securities were 19.8% and 19.3% of average interest-earning assets in 2014 and 2013, respectively. Total average interest-earning assets increased $309.7 million, or 21.9%, in 2014 compared to 2013.

Table 2 Analysis of Changes in Net Interest Income

The following table presents the effects of changes in average balances (volume) or changes in average rates on net interest income for the years indicated. Volume variances are equal to the increase or decrease in average balances multiplied by prior period rates. Rate variances are equal to the increase or decrease in rates multiplied by prior period average balances. Mix variances are attributable to the change in yields or rates multiplied by the change in average balances.

Provision for Loan Losses

Management assesses the adequacy of the allowance for loan losses on a quarterly basis based on several factors including growth of the loan portfolio, analysis of probable losses in the portfolio, recent loss experience and the current economic climate. Actual losses on loans are charged against the allowance, and the allowance is increased by loss recoveries and provisions for loan losses charged to expense. For further discussion, see the section captioned “Critical Accounting Policies.”

Our provision for loan losses totaled $500 thousand in 2015, compared to $750 thousand in 2014 and $540 thousand in 2013. The decrease compared to 2014 primarily relates to a lower level of impaired loans from the successful resolution of problem loans, as well as a decrease in classified loans. The allowance for loan losses of $15.0 million totaled 1.03% of loans at December 31, 2015, compared to 1.11% at December 31, 2014. Net charge-offs in 2015 totaled $600 thousand and were primarily related to one land development loan that was sold, compared to net recoveries of $125 thousand in the prior year. See the section captioned “Allowance for Loan Losses” below for further analysis of the provision for loan losses.

2015 Compared with 2014:

Non-interest income totaled $9.2 million and $9.0 million at December 31, 2015 and December 31, 2014, respectively. The increase compared to the prior year primarily relates to the increase in dividends on Federal Home Loan Bank ("FHLB") stock, due to a $305 thousand special dividend from the FHLB and higher annualized dividend rates in 2015. The increase was partially offset by lower merchant interchange fees due to decreased transaction volume and lower service charges on deposit accounts compared to 2014.

2014 Compared with 2013:

Service charges on deposit accounts increased in 2014 when compared to 2013 primarily due to increased volume related to the NorCal Acquisition.

The increase in Wealth Management and Trust Services ("WMTS") income in 2014 compared to 2013 is due to the acquisition of new assets and market value appreciation of existing assets under management. Assets under management totaled approximately $352.2 million at December 31, 2014 and $335.9 million at December 31, 2013.

Debit card interchange fees increased in 2014 when compared to the prior year primarily due to an increase in the volume of debit card usage. Bank-owned life insurance (“BOLI”) income decreased in 2014 compared to 2013 due to a $228 thousand benefit realized on the death of an insured employee in the first quarter of 2013, partially offset by earnings from additional policies.

Other income increased when compared to the prior year primarily due to higher dividend income from the FHLB and higher commission income from mortgage brokerage activity. We discontinued the small mortgage brokerage acquired from Bank of Alameda effective June 30, 2014 and the financial impact has not been material.

2015 Compared with 2014:

The increase in salaries and related benefits was mainly due to higher employee benefits and lower deferred loan origination costs. These expenses were partially off-set by lower salaries, commissions and associated payroll taxes in 2015 mainly related to the absence of acquisition-related personnel costs. The number of average FTE employees totaled 260 in 2015 and 266 in 2014.

The increase in depreciation and amortization is primarily due to non-recurring accounting adjustments in 2015.

The decrease in data processing expenses in 2015 mainly reflects one-time NorCal Acquisition-related expenses totaling $442 thousand in the first quarter of 2014 related to the system conversion.

The reversal of provision for losses on off-balance sheet commitments was primarily due to a refinement in methodology used in the calculation of the loss reserve on these commitments by incorporating rolling four-quarter and average commitment usage, as well as eliminating outlier data for small commitment categories. Going forward we expect the result of the refined methodology to reduce the fluctuation in the provision for losses on off-balance sheet commitments.

2014 Compared with 2013:

The increase in salaries and benefit expenses was mainly due to higher salaries and commissions and associated payroll taxes, due to an increase in personnel from the NorCal Acquisition and the addition of commercial lenders, as well as higher costs incurred in 2014 with the temporary NorCal Acquisition integration staff. These expenses were partially offset by higher capitalized and deferred loan origination costs. The number of average FTE employees totaled 266 in 2014 and 242 in 2013.

The increase in occupancy and equipment primarily reflects higher rent and common area maintenance expenses and other occupancy expenses related to new facilities from the NorCal Acquisition.

Page-31

The decrease in data processing expenses in 2014 primarily reflects one-time acquisition-related expenses totaling $2.8 million in the fourth quarter of 2013, mainly relating to NorCal's core processing system contract termination and deconversion fees, partially offset by $746 thousand of NorCal deconversion expense recognized in the first quarter of 2014 and increased data processing transaction volumes due to the NorCal Acquisition.

Professional service expenses in 2014 decreased when compared to 2013. This is primarily due to $660 thousand of 2013 professional and legal fees related to the NorCal Acquisition and cost savings on various professional services in 2014.

The increase in the provision for off-balance sheet commitments in 2014 was primarily due to a change in allowance for loan loss methodology, which is applied to these commitments as well as the allowance for loan losses. $771 thousand amortization of core deposit intangibles from the NorCal Acquisition were recorded in other expense in 2014 compared to $69 thousand in 2013. FDIC insurance and other expenses include higher on-going expenses as a result of larger size and increased transaction volume.

Provision for Income Taxes

The provision for income taxes totaled $10.5 million at an effective tax rate of 36.3% in 2015, compared to $11.7 million at an effective tax rate of 37.2% in 2014 and $7.9 million at an effective tax rate of 35.7% in 2013. The decrease in both the provision for income taxes and the effective tax rate from the prior year is primarily due to a lower amount of pre-tax income and higher amounts of tax-exempt earnings on investment securities and loans. These provisions reflect accruals for taxes at the applicable rates for federal income tax and California franchise tax based upon reported pre-tax income, and adjusted for the effects of all permanent differences between income for tax and financial reporting purposes (such as earnings on qualified municipal securities, BOLI and certain tax-exempt loans). Therefore, there are fluctuations in the effective rate from period to period based on the relationship of net permanent differences to income before tax.

Additionally, effective tax rates reflect the adoption of the amended FASB Accounting Standards Codification ("ASC") Topic 323-740 Investments—Equity Method and Joint Ventures—Income Taxes. Beginning in 2014, we adopted this ASU to apply the proportional amortization methodology in accounting for low income tax credit investments. In accordance with ASC 323-740, the tax credit investment amortization expense is now presented as a component of provision for income taxes. Previously, the amortization expense was included as non-interest expense. This change resulted in lower non-interest expense, increased income tax expense and an increased effective tax rate, but did not alter the amount of income taxes actually paid by the Bank. For further discussion, see Note 1, Note 3 and Note 12 to Item 8. Financial Statements and Supplementary Data.

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. In June 2015, the State of California completed its examination of the 2011 and 2012 corporate income tax returns, resulting in a minor adjustment. At December 31, 2015 and 2014, neither the Bank nor Bancorp had accruals for interest and penalties related to unrecognized tax benefits.

FINANCIAL CONDITION

Investment Securities

We maintain an investment securities portfolio to provide liquidity and to generate earnings on funds that have not been loaned to customers. Management determines the maturities and types of securities to be purchased based on liquidity and the desire to attain a reasonable investment yield balanced with risk exposure. Table 5 shows the composition of the debt securities portfolio by expected maturity at December 31, 2015 and 2014. Expected maturities differ from contractual maturities because the issuers of the securities may have the right to call or prepay obligations with or without call or prepayment penalties. We estimate and update expected maturity dates regularly based on current and historical prepayment speeds. The weighted average maturity of the portfolio at December 31, 2015 was approximately four years.

¹Book value reflects cost, adjusted for accumulated amortization and accretion.

²Weighted average yields on tax-exempt basis and weighted average calculation is based on amortized cost of securities.

The amortized cost of our investment securities portfolio increased $171.6 million or 54.4% during 2015 in order to deploy temporary excess liquidity from deposit growth earlier in 2015. $289.5 million in securities were purchased in

Page-33

2015 and were designated as available-for-sale to provide the flexibility for liquidity management. These purchases were partially offset by $112.0 million of paydowns and maturities, and $3.1 million of sales during 2015.

During 2015, we purchased $172.0 million in agency debentures issued by FNMA, Federal Farm Credit Bureau, FHLB and FHLMC, $65.5 in million mortgage pass-through securities, $44.5 million in municipal securities, and $7.5 million in collateralized mortgage obligations ("CMOs"). We consider agency debentures, mortgage-backed securities, and CMOs issued by U.S. government sponsored entities to have low credit risk as they carry the implicit backing of the U.S. Government. We also invest in municipalities with sound credit fundamentals. The debentures and MBS issued by the U.S. government sponsored agencies, state and municipal securities and corporate bonds, made up 74.5%, 20.5% and 4.1% of the portfolio at December 31, 2015, compared to 58.4%, 25.0% and 14.3%, respectively at December 31, 2014. See the discussion in the section captioned “Securities May Lose Value due to Credit Quality of the Issuers” in Item 1A Risk Factors above.

Any investment securities in our portfolio that may be backed by sub-prime or Alt-A mortgages, which account for approximately 0.2% of our total securities portfolio, relate to privately issued CMOs. See Note 3 to the Consolidated Financial Statements in Item 8, for more information on investment securities.

At December 31, 2015, distribution of our investment in obligations of state and political subdivisions was as follows:

The portion of the portfolio outside the state of California is distributed among 18 states. The largest concentrations outside California are in Minnesota (8.5%), Washington (8.3%), and Texas (6.4%). Revenue bonds, both within and outside California, primarily consisted of bonds relating to essential services (such as roads and utilities) and school district bonds.

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 local employers, income indices and home values


•	For revenue bonds, the source and strength of revenue for municipal authorities including obligor’s financial condition and reserve levels, annual debt service and debt coverage ratio, and credit enhancement (such as insurer’s strength)


•	Credit ratings by major credit rating agencies

¹ Our residential loan portfolio includes no sub-prime loans, nor is it our normal practice to underwrite loans commonly referred to as "Alt-A mortgages", the characteristics of which are loans lacking full documentation, borrowers having low FICO scores or collateral compositions reflecting high loan-to-value ratios. Substantially all of our residential loans are indexed to Treasury Constant Maturity Rates and have provisions to reset five years after their origination dates.

2015 was highlighted by record new loan volume of approximately $252 million for the year, compared to approximately $192 million in 2014, as we continued to strengthen our markets throughout our footprint.

Commercial loans increased $9.2 million in 2015 and $26.9 million in 2014. We successfully expanded our lending in strategic market segments such as wine-related industries in 2015.

Commercial real estate loans increased $54.1 million in 2015 and $38.0 million in 2014. Of the commercial real estate loans at December 31, 2015, 75% were non-owner occupied and 25% were owner occupied. This compares to 74% non-owner occupied and 26% owner occupied at December 31, 2014. Our commercial real estate loan portfolio is weighted towards term loans for which the primary source of repayment is cash flow from net operating income of the real estate property. Originated loans are subject to our conservative credit underwriting standards and both the acquired and originated loans are actively managed.

The following table summarizes our commercial real estate loan portfolio by the geographic location in which the property is located as of December 31, 2015 and 2014:

Construction loans increased $17.1 million in 2015 and $16.8 million in 2014. The increase in 2015 was due to substantial draws on existing single family development construction projects as they approached completion and origination of new construction loans. The improving economy resulted in a number of new financing opportunities for existing customers who had successfully completed construction projects in the past.

Approximately 85% and 87% of our outstanding loans were secured by real estate at December 31, 2015 and 2014, respectively. Also see Item 1A, Risk Factors, regarding our loan concentration risk.

At December 31, 2015 and 2014, approximately 1.5% and 1.0%, respectively, of our loans contained an interest-only feature as part of the loan terms. All of these loans were current with their payments as of December 31, 2015. Except for two loans to one borrowing relationship totaling $7.0 million, all were considered to have low credit risk (graded "Pass").

As of December 31, 2015 and 2014, approximately $43.4 million and $31.3 million, respectively, of our loans had interest reserves, all of which were construction loans. When we determine a loan is impaired before the interest reserve has been depleted, the interest funded by the interest reserve is applied against loan principal. As of December 31, 2015 and 2014, no construction loans having interest reserve balances were determined to be impaired.

The following table presents the maturity distribution of our commercial and construction loans as of December 31, 2015 based on their contractual maturity dates and does not include scheduled payments or potential prepayments.

The following table shows the mix of variable-rate loans to fixed-rate loans for commercial and construction loans. The large majority of the variable-rate loans are tied to independent indices (such as the Wall Street Journal prime rate or a Treasury Constant Maturity Rate). Most loans with original terms of more than five years have provisions for the fixed rates to reset, or convert to variable rates, after one, three or five years. These loans are included in variable rate balances.

Allowance for Loan Losses

Credit risk is inherent in the business of lending. As a result, we maintain an allowance for loan losses to absorb possible losses in our loan portfolio through a provision for loan losses charged against earnings. All specifically identifiable and quantifiable losses are charged off against the allowance. The balance of our allowance for loan losses is Management's best estimate of the remaining probable losses in the portfolio. The ultimate adequacy of the allowance is dependent upon a variety of factors beyond our control, including the real estate market, changes in interest rates and economic and political environments. Based on the current conditions of the loan portfolio, Management believes that the $15.0 million allowance for loan losses at December 31, 2015 is adequate to absorb losses in our loan portfolio. No assurance can be given, however, that adverse economic conditions or other circumstances will not result in increased losses in the portfolio.

The Components of the Allowance for Loan Losses

As stated previously in “Critical Accounting Policies,” and Note 1 to the Consolidated Financial Statements in this report, the overall allowance consists of 1) specific allowances for individually identified impaired loans ("ASC 310-10") and 2) general allowances for pools of loans ("ASC 450-20"), which incorporate changing qualitative and environmental factors (e.g., portfolio growth and trends, credit concentrations, economic and regulatory factors, etc.).

The first component, specific allowances, results from the analysis of identified problem credits and the evaluation of sources of repayment including collateral, as applicable. Through Management's ongoing loan grading and credit monitoring process, individual loans are identified that have conditions indicating the borrower may be unable to pay all amounts due in accordance with the contractual terms. These loans are evaluated for impairment individually by Management. Management considers an originated loan to be impaired when it is probable we will be unable to collect all amounts due according to the contractual terms of the loan agreement. For PCI loans, specific allowances are established to account for credit deterioration subsequent to acquisition if we have probable decreases in cash flows expected to be collected. For loans determined to be impaired, the extent of the impairment is measured 1) based on the present value of expected future cash flows discounted at the loan's effective interest rate at origination for originated loans (or discounted at the effective yield for PCI loans), 2) based on the loan's observable market price; or 3) based on the fair value of the collateral if the loan is collateral dependent or if foreclosure is imminent. Generally with problem

Page-37

credits that are collateral dependent, we obtain appraisals of the collateral at least annually. We may obtain appraisals more frequently if we believe the collateral value is subject to market volatility, if a specific event has occurred to the collateral, or if we believe foreclosure is imminent. Impaired loan balances decreased to $21.2 at December 31, 2015 from $25.2 million at December 31, 2014. The decrease primarily relates to payoffs, sale, and paydowns of several large impaired loans, as well as five loans that were no longer considered modified as a troubled debt restructuring (“TDR”). The specific allowance increased slightly to $1.2 million at December 31, 2015 from $1.1 million at December 31, 2014.

The second component is an estimate of the probable inherent losses in each loan pool with similar risk characteristics. Loans are evaluated on a pool basis by loan segment which is further delineated by Federal regulatory reporting codes ("CALL codes"). Each segment is assigned an expected loss factor which is derived from a rolling twenty-quarter look-back at our historical losses for that particular segment, as well as other qualitative factors. This analysis encompasses the entire loan portfolio and excludes acquired loans where the purchase discount has not been fully accreted. At December 31, 2015 and 2014, the allowance allocated for the second component by categories of credits totaled $13.8 million and $14.0 million, respectively. The allocated allowance related to historical charge-off experience, totaled $2.3 million and $2.8 million at December 31, 2015 and 2014, respectively. In addition, the allocated allowance related to objective qualitative factors such as: changes in the volume and nature of the loan portfolio, changes in credit quality metrics (past due loans, non-accrual loans, net charge-offs, adversely-graded loans), and the existence of credit concentrations totaled $4.9 million and $4.4 million at December 31, 2015 and 2014, respectively. The remaining amounts were allocated based on subjective factors including changes in the overall economic environment, legal and regulatory conditions, lending management and other relevant staff, uncertainties related to acquisitions, as well as the quality of our loan review process.

Table 10 shows the allocation of the allowance by loan type as well as the percentage of total loans in each of the same loan types.

Table 11 shows the activity in the allowance for loan losses for each of the years in the five-year period ended December 31, 2015. Net charge-offs totaled $600 thousand in 2015, compared to net recoveries of $125 thousand in 2014. Charge-offs in 2015 were primarily comprised of an $839 charge-off related to a land development loan that was sold. The percentage of net charge-offs (recoveries) to average loans was 0.04% in 2015, compared to (0.01)% in 2014 and 0.00% in 2013, reflecting the factors discussed above.

Non-performing assets for each of the past five years are presented below. The decrease in non-performing loans from 2014 to 2015 primarily relates to a previously non-performing loan that was returned to accrual status, the payoff of a commercial real estate loan, and a land development loan that was sold. The decrease in non-accrual loans from 2013 to 2014 primarily relates to the successful resolution of several problem loans that led to pay offs, pay downs or resumption of payments on these loans. The decrease in non-performing loans from 2012 to 2013 primarily reflects one commercial real estate loan that paid off in 2013 and pay downs on various commercial real estate and commercial loans, partially offset by one delinquent land development loan that went on to non-accrual status in 2013. The ratio of allowance for loan losses to non-accrual loans increased to 688.3% at December 31, 2015 from 161.5% at December 31, 2014.

Troubled debt restructured loans, whose contractual terms have been restructured in a manner which grants a concession to a borrower experiencing financial difficulties, totaled $19.1 million and $22.7 million as of December 31, 2015 and 2014, respectively. The decrease primarily relates to five loans that were removed from TDR designation, one sold TDR loan and payoffs and paydowns of several other TDR loans. For more information, refer to Note 4 under “Troubled Debt Restructuring”.

BOLI totaled $29.5 million at December 31, 2015, compared to $28.6 million at December 31, 2014, and is recorded in other assets. Other assets also included net deferred tax assets of $12.7 million and $12.6 million at December 31, 2015 and 2014, respectively. These deferred tax assets consist primarily of tax benefits expected to be realized in future periods related to net operating loss carryforwards, temporary differences of allowance for loan losses, fair value adjustments on acquired loans, deferred compensation, and accrued but unpaid expenses. The increase in deferred tax assets in 2015 primarily relates to the change in the net unrealized gain/loss on securities available-for-sale, increase in interest received on nonaccrual loans, offset by the utilization of net operating loss carryforwards from the NorCal Acquisition and reduction in deferred assets associated with accretion on purchase discounts on acquired loans. Management believes these deferred tax assets to be realizable due to our consistent record of earnings and the expectation that earnings will continue at a level adequate to realize such benefits. Therefore, no valuation allowance has been established as of December 31, 2015 or 2014.

In addition, we held $8.4 million and $8.2 million of FHLB stock recorded at cost in other assets at December 31, 2015 and 2014, respectively. The FHLB paid $1.0 million and $563 thousand in cash dividends in 2015 and 2014, respectively. On February 18, 2016, the FHLB declared a cash dividend for the fourth quarter of 2015 at an annualized dividend rate of 7.99%. Other assets as of December 31, 2015 also included goodwill of $6.4 million and a core deposit intangible asset, net of amortization, totaling $3.1 million from the NorCal Acquisition.

Deposits

Deposits, which are used to fund our interest earning assets, increased $176.6 million, or 11.4%, in 2015. The increase in deposits in 2015 compared to 2014 is primarily due to the expansion of business by many of our commercial depositors as well as the acquisition of key clients. Non-interest bearing deposits totaled $770.1 million at December 31, 2015, an increase of $99.2 million when compared to December 31, 2014. Non-interest bearing deposits totaled 44.6% of total deposits as of December 31, 2015, compared to 43.2% at December 31, 2014. No individual customer accounted for more than 5% of deposits.

The increase in CDARS balances resulted from redirecting certain accounts back onto our balance sheet as part of our contingency funding testing and management.

Borrowings

As of December 31, 2015 and 2014, respectively, we had $470.6 million and $450.6 million in secured lines of credit with FHLB, $37.8 million and $27.7 million with Federal Reserve Bank of San Francisco (“FRBSF”), and $92.0 million and $72.0 million in unsecured lines with correspondent banks to cover any short or long-term borrowing needs. As of December 31, 2015, we had one long-term FHLB fixed-rate advance outstanding totaling $15.0 million. We also incurred overnight borrowing from FHLB totaling $52.0 million (due to significant funding of loans and deposit volatility associated with a few large depositors in the fourth quarter of 2015) and a standby letter of credit totaling $241 thousand as of December 31, 2015, leaving $403.4 million available borrowing capacity with FHLB. As of December 31, 2014, we had one FHLB fixed-rate advance outstanding totaling $15.0 million and a standby letter of credit totaling $241 thousand, leaving $435.3 million available borrowing capacity with FHLB. The FRBSF and correspondent bank lines were not utilized at December 31, 2015 and 2014. For additional information, see Note 8 to the Consolidated Financial Statements in Item 8 of this Form 10-K.

As part of the NorCal Acquisition, we assumed two subordinated debentures due to the NorCal Community Bancorp Trusts I and II at fair values totaling $5.0 million and contractual values totaling $8.2 million at the acquisition date. The subordinated debentures have been accreted up to $5.4 million and $5.2 million as of December 31, 2015 and 2014. For additional information on our subordinated debentures, see Note 8 to the Consolidated Financial Statements in Item 8 of this Form 10-K.

Deferred Compensation Obligations

We maintain a non-qualified, unfunded deferred compensation plan for certain key management personnel. Under this plan, participating employees may defer compensation, which will entitle them to receive certain payments for up to fifteen years commencing upon retirement, death, disability or termination of employment. The participating employee may elect to receive payments over periods not to exceed fifteen years. At December 31, 2015 and 2014, our aggregate payment obligations under this plan totaled $3.0 million and $2.9 million, respectively.

We established a Salary Continuation Plan on January 1, 2011. The plan was to provide a percentage of salary continuation benefits to a select group of Executive Management upon retirement at age sixty-five and reduced benefits upon early retirement. At December 31, 2015 and 2014, our liability under the Salary Continuation Plan was $823 thousand and $645 thousand, respectively, and is recorded in interest payable and other liabilities. This Plan is unfunded and non-qualified for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974.

For additional information, see Note 11 to the Consolidated Financial Statements in Item 8 of this Form 10-K.

The contractual amount of loan commitments not reflected on the consolidated statement of condition was $376.6 million and $349.3 million at December 31, 2015 and 2014, respectively.

As permitted or required under California law and to the maximum extent allowable under that law, we have certain obligations to indemnify our current and former officers and directors for certain events or occurrences while the officer or director is, or was serving, at our request in such capacity. These indemnification obligations are valid as long as the director or officer acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, our best interests, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The maximum potential amount of future payments we could be required to make under these indemnification obligations is unlimited; however, we have a director and officer insurance policy that mitigates our exposure and enables us to recover a portion of any future amounts paid. As we believe the possibility of potential claims to be remote and any amounts under the indemnifications would be covered by the insurance policy, we have not recorded an indemnification obligation.

Capital Adequacy

As discussed in Note 16 to the Consolidated Financial Statements, the Bank's capital ratios are above regulatory guidelines to be considered "well capitalized" and Bancorp's ratios exceed the required minimum ratios for capital adequacy purposes. The Bank's total risk-based capital ratio decreased from 13.7% at December 31, 2014 to 13.1% at December 31, 2015, primarily due to an increase in risk-weighted assets, driven mainly by an increase in the loan portfolio, partially offset by the accumulation of undistributed net income of the Bank in 2015 of $12.7 million. Bancorp's total risk-based capital ratio decreased from 13.9% at December 31, 2014 to 13.4% at December 31, 2015, primarily due to an increase in risk-weighted assets as discussed above, partially offset by the accumulation of undistributed net income of $13.1 million in 2015.

We expect to maintain strong capital levels. Our anticipated sources of capital in 2016 include future earnings and shares issued upon the exercise of stock options.

Liquidity

The goal of liquidity management is to provide adequate funds to meet loan demand and 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 needed. Our ALCO, which is comprised of certain directors of the Bank, is responsible for approving and monitoring our liquidity targets and strategies. ALCO has approved a contingency funding plan that addresses decreases in liquidity below internal requirements.

Page-44

We obtain funds from the repayment and maturity of loans as well as deposit inflows, investment security maturities and paydowns, federal funds purchases, FHLB advances, and other borrowings. Our primary uses of funds are the origination of loans, the purchase of investment securities, withdrawals of deposits, maturity of certificate of deposits, repayment of borrowings and dividends to common stockholders.

Management monitors our liquidity position daily. Our liquid assets totaled $375.0 million and $198.6 million at December 31, 2015 and 2014, respectively, which included unencumbered available-for-sale securities and cash. We attract and retain new deposits, which depends upon the variety and effectiveness of our customer account products, service and convenience, and rates paid to customers, as well as our financial strength. Any long-term decline in retail deposit funding would adversely affect our liquidity. Management regularly adjusts our investments in liquid assets based upon our assessment of expected loan demand, expected deposit flows, yields available on interest-earning securities and the objectives of our asset/liability management program. In addition, we have secured borrowing capacity through the FHLB and FRBSF that can be drawn upon. Management anticipates our current strong liquidity position and core deposit base will provide adequate liquidity to fund our operations.

As presented in the accompanying consolidated statements of cash flows, the sources of liquidity vary between periods. Our cash and cash equivalents at December 31, 2015 totaled $26.3 million, a decrease of $15.0 million from December 31, 2014. The primary sources of funds during 2015 included $115.1 million in paydowns, maturities and sales of investment securities, a net increase of $176.6 million in deposits, $52.0 million FHLB borrowings and $23.7 million in net cash provided by operating activities. The primary uses of funds were $289.5 million in investment securities purchases, $88.1 million of loan originations, net of principal collections, and $5.4 million cash dividends paid on common stock to our shareholders.

In addition to cash and cash equivalents, we have substantial additional borrowing capacity including unsecured lines of credit totaling $92.0 million with correspondent banks. Further, our borrowing capacity with the FRBSF totaled $37.8 million at December 31, 2015, and is secured by a certain residential loan portfolio. As of December 31, 2015, there is no debt outstanding to correspondent banks or the FRBSF. We are also a member of the FHLB and have a line of credit (secured under terms of a blanket collateral agreement by a pledge of essentially all of our unencumbered financial assets) in the amount of $470.6 million, of which $403.4 million was available at December 31, 2015. Borrowings under the line are limited to eligible collateral. The interest rates on overnight borrowings with both correspondent banks and the FHLB are determined daily and generally approximate the target federal funds rate.

Undisbursed loan commitments, which are not reflected on the consolidated statements of condition, totaled $376.6 million at December 31, 2015 at varying rates. This amount included $191.3 million under commercial lines of credit (these commitments are contingent upon customers maintaining specific credit standards), $130.4 million under revolving home equity lines, $39.4 million under undisbursed construction loans, $4.4 million under standby letters of credit and a remaining $11.1 million under personal and other lines of credit. These commitments, to the extent used, are expected to be funded primarily through the repayment of existing loans, deposit growth and existing balance sheet liquidity. Over the next twelve months $113.2 million of time deposits will mature. We expect these funds to be replaced with new deposits. Our emphasis on local deposits combined with our well capitalized equity position, provides a very stable funding base.

Since Bancorp is a holding company and does not conduct regular banking operations, its primary sources of liquidity are dividends from the Bank. Under the California Financial Code, payment of a dividend from the Bank to Bancorp without advance regulatory approval is restricted to the lesser of the Bank’s retained earnings or the amount of the Bank’s undistributed net profits from the previous three fiscal years. The primary uses of funds for Bancorp are shareholder dividends and ordinary operating expenses. Bancorp held $3.8 million of cash at December 31, 2015. Bancorp obtained a dividend distribution from the Bank in the amount of $3.0 million in January of 2016. These funds are deemed sufficient to cover Bancorp's operational needs and cash dividends to shareholders for the next twelve months. Management anticipates that there will be sufficient earnings at the Bank level to provide dividends to Bancorp to meet its funding requirements for the foreseeable future.

ITEM 7A. 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 form of market risk is interest rate risk, which is inherent in our investment, borrowing, lending 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.

To mitigate interest rate risk, the structure of the Consolidated Statement of Condition is managed with the objective of correlating the effects of interest rate changes on loans and investments with those of deposits and borrowings. The asset liability management policy sets limits on the acceptable amount of change to net interest income and economic value of equity in different interest rate environments.

From time to time, we enter into interest rate swap contracts to mitigate the changes in the fair value of specified long-term fixed-rate loans and firm commitments to enter into long-term fixed-rate loans caused by changes in interest rates. See Note 15 to the Consolidated Financial Statements in Item 8 of this Form 10-K.

Exposure to interest rate risk is reviewed at least quarterly by ALCO and the Board of Directors. Simulation models are used to measure interest rate risk and to evaluate strategies to improve profitability. A simplified statement of condition is prepared on a quarterly basis as a starting point, using as inputs actual loans, investments, borrowings and deposits. If potential changes to net equity 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.

In December 2015, the FOMC raised the target federal funds rate by 25 basis points to a range of 0.25% to 0.50%. This increase from the historic low of 0.00% to 0.25% had not changed for the past seven years. The Bank currently has low interest rate risk and is asset sensitive (net interest margin is expected to increase if rates go up and adjustable rate loans at their interest rate floors start to float again as they reprice. However, there may be a lag between repricing of certain floating rate loans at their floors and increases in rates).

Page-46

Based on our most recent simulation, net interest income is projected to increase by approximately 2% in year one given an immediate 200 basis point increase in interest rates. For modeling purposes, the likelihood of a decrease in interest rates beyond 25 basis points as of December 31, 2015 was considered to be remote given prevailing low interest rate levels. The interest rate risk is within policy guidelines established by ALCO and the Board of Directors.

The following table estimates the effect of interest rate changes in all points of the yield curve as measured against a flat rate scenario.



Table 17	Effect of Interest Rate Change on Net Interest Income (NII) at December 31, 2015

	Immediate Changes in Interest Rates (in basis points)	Estimated Change in NII in Year One (as percent of NII)
	up 400	2.4%
	up 300	2.1%
	up 200	1.6%
	up 100	0.9%

As stated previously in the section captioned "Supervision and Regulation" in Item 1 Business of this report, the Dodd-Frank Act repealed the federal prohibitions on the payment of interest on business demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts beginning July 21, 2011. We have not incurred significant interest expense on business transaction accounts since the legislation took effect in July 2011. If we were to pay interest on certain deposits that are currently non-interest bearing, causing these deposits to become rate sensitive in the future, we would become less asset sensitive than the model currently indicates.

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. 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, although certain of our assets and liabilities may have similar maturities or repricing time frames, they may react differently to changes in market interest rates. In addition, the effect of changes in interest rates on certain categories of either our assets or liabilities may precede or lag changes in market interest rates. Further, the actual rates and timing of prepayments on loans and investment securities, and the behavior of depositors, could vary significantly from the assumptions applied in the various scenarios. Lastly, changes in U.S. Treasury rates accompanied by a change in 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 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders

Bank of Marin Bancorp

We have audited the accompanying consolidated statements of condition of Bank of Marin Bancorp and subsidiary (the “Company”) as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive income, changes in stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2015. We also have audited the Company's internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting and Compliance with Applicable Laws and Regulations. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall consolidated financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Bank of Marin Bancorp and subsidiary as of December 31, 2015 and 2014, and the consolidated results of their operations and their cash flows each of the three years in the period ended December 31, 2015, in conformity with generally accepted accounting principles in the United States of America. Also in our opinion, Bank of Marin Bancorp maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

To the Shareholders:

Management's Report on Internal Control over Financial Reporting and Compliance with Applicable Laws and Regulations

Management of the Bank of Marin Bancorp and its subsidiary (”Bancorp”) is responsible for preparing the Bancorp's annual consolidated financial statements in accordance with generally accepted accounting principles. Management is also responsible for establishing and maintaining internal control over financial reporting, including controls over the preparation of regulatory financial statements, and for complying with the designated safety and soundness laws and regulations pertaining to insider loans and dividend restrictions. Bancorp's internal control contains monitoring mechanisms, and actions are taken to correct deficiencies identified.

There are inherent limitations in the effectiveness of any internal control, including the possibility of human error and the circumvention or overriding of controls. Accordingly, even effective internal control can provide only reasonable assurance with respect to financial statement preparation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

Management has assessed Bancorp's internal control over financial reporting encompassing both financial statements prepared in accordance with generally accepted accounting principles and those prepared for regulatory reporting purposes as of December 31, 2015. The assessment was based on criteria for effective internal control over financial reporting described in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, Management believes that, as of December 31, 2015, Bancorp maintained effective internal control over financial reporting encompassing both financial statements prepared in accordance with generally accepted accounting principles and those prepared for regulatory reporting purposes in all material respects. Management also believes that Bancorp complied with the designated safety and soundness laws and regulations pertaining to insider loans and dividend restrictions during 2015.

Management's assessment of the effectiveness of Bancorp's internal control over financial reporting as of December 31, 2015 has been audited by Moss Adams LLP, an independent registered public accounting firm, which expresses an unqualified opinion as stated in their report which appears on the previous page.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Summary of Significant Accounting Policies

Basis of Presentation: The consolidated financial statements include the accounts of Bank of Marin Bancorp (“Bancorp”), a bank holding company, and its wholly-owned bank subsidiary, Bank of Marin (the “Bank”), a California state-chartered commercial bank. References to “we,” “our,” “us” mean the holding company and the Bank that are consolidated for financial reporting purposes. All material intercompany transactions have been eliminated. We have evaluated subsequent events through the date of filing with the Securities and Exchange Commission (“SEC”) and have determined that there are no subsequent events that require additional recognition or disclosure.

On November 29, 2013, we completed the merger of NorCal Community Bancorp ("NorCal"), parent company of Bank of Alameda, to enhance our market presence (the “NorCal Acquisition”). On the date of acquisition, Bancorp assumed ownership of NorCal Community Bancorp Trusts I and II, respectively (the "Trusts"), which were formed for the sole purpose of issuing trust preferred securities. Bancorp is not considered the primary beneficiary of the Trusts (variable interest entities), therefore the Trusts are not consolidated in our consolidated financial statements, but rather the subordinated debentures are shown as a liability on our consolidated statements of condition. Bancorp's investment in the common stock of the Trusts is accounted for under the equity method and is included in interest receivable and other assets on the consolidated statements of condition.

Nature of Operations: Bancorp, headquartered in Novato, CA, conducts business primarily through its wholly-owned subsidiary, the Bank, which provides a wide range of financial services to customers, who are predominantly professionals, small and middle-market businesses, and individuals who work and/or reside in Marin, Sonoma, Napa, San Francisco and Alameda counties. Besides the headquarters office in Novato, CA, the Bank operates ten branches in Marin County, one in Napa County, one in San Francisco, five in Sonoma County and three in Alameda County. Our accounting and reporting policies conform to generally accepted accounting principles, general practice, and regulatory guidance within the banking industry. A summary of our significant policies follows.

Cash and Cash Equivalents include cash, due from banks, federal funds sold and other short-term investments with maturity less than three months at the time of origination.

Investment Securities are classified as "held-to-maturity," "trading securities" or "available-for-sale." Investments classified as held-to-maturity are those that we have the ability and intent to hold until maturity and are reported at cost, adjusted for the amortization or accretion of premiums or discounts. Investments held for resale in anticipation of short-term market movements are classified as trading securities and are reported at fair value, with unrealized gains and losses included in earnings. Investments that are neither held-to-maturity nor trading are classified as available-for-sale and are reported at fair value. Unrealized gains and losses for available-for-sale securities, net of related tax, are reported as a separate component of comprehensive income and included in stockholders' equity until realized. For discussion of our methodology in determining fair value, see Note 10.

At each financial statement date, we assess whether declines in the fair value of held-to-maturity and available-for-sale securities below their costs are deemed to be other-than-temporary. We consider, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) our intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in fair value. Evidence evaluated includes, but is not limited to, the remaining payment terms of the instrument and economic factors that are relevant to the collectability of the instrument, such as: current prepayment speeds, the current financial condition of the issuer(s), industry analyst reports, credit ratings, credit default rates, interest rate trends, the quality of any credit enhancement and the value of any underlying collateral.

For each security in an unrealized loss position ("impaired security"), we assess whether we intend to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If we intend to sell the security or it is more likely than not we will be required to sell the security before recovery of its amortized cost basis, the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date is recognized against earnings.

For impaired securities that are not intended for sale and will not be required to be sold prior to recovery of our amortized cost basis, we determine if the impairment has a credit loss component. For both held-to-maturity and available-for-

Page-54

sale securities, if the amount of cash flows expected to be collected are less than the amortized cost, an other-than-temporary impairment shall be considered to have occurred and the credit loss component is recognized against earnings as the difference between present value of the expected future cash flows and the amortized cost. In determining the present value of the expected cash flows, we discount the expected cash flows at the effective interest rate implicit in the security at the date of purchase. The remaining difference between the fair value and the amortized basis is deemed to be due to factors that are not credit related and is recognized in other comprehensive income, net of applicable taxes.

For held-to-maturity securities, if there is no credit loss component, no impairment is recognized. The portion of other-than-temporary impairment recognized in other comprehensive income for credit impaired debt securities classified as held-to-maturity is accreted from other comprehensive income to the amortized cost of the debt security over the remaining life of the debt security in a prospective manner on the basis of the amount and timing of future estimated cash flows.

Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned. Realized gains and losses on the sale of securities and credit losses related to other-than-temporary impairment on available-for-sale and held-to-maturity securities are included in non-interest income as gains (losses) on investment securities, net. The specific identification method is used to calculate realized gains and losses on sales of securities.

Originated Loans are reported at the principal amount outstanding net of deferred fees (costs), charge-offs and the allowance for loan losses (“ALLL”). Interest income is accrued daily using the simple interest method. Loans are placed on non-accrual status when Management believes that there is doubt as to the collection of principal or interest, generally when they become contractually past due by ninety days or more with respect to principal or interest, except for loans that are well-secured and in the process of collection. When loans are placed on non-accrual status, any accrued but uncollected interest is reversed from current-period interest income. Non-accrual loans may be returned to accrual status when one of the following occurs:


•	The loan is brought current or after all principal and past due interest has been collected, and we are satisfied with the borrower's financial position and we are reasonably assured as to repayment.


•	The loan has become well secured and is in the process of collection.

•

We are satisfied with the borrower’s financial position, the obligor has resumed paying the full amount of the contractual interest and principal, the amounts contractually due are reasonably assured of repayment within a reasonable period, and there has been a sustained period of repayment performance (generally, six consecutive monthly payments), according to the modified terms for loans whose contractual terms have been restructured in a manner which grants a concession to a borrower experiencing financial difficulties (“troubled debt restructuring”).

Loan origination fees and commitment fees, offset by certain direct loan origination costs, are deferred and amortized as yield adjustments over the contractual lives of the related loans.

Loan Charge-Off Policy: For all loan types excluding overdraft accounts, we generally make a charge-off determination at or before 90 days past due. A collateral-dependent loan is partially charged down to the fair value of collateral securing it if: (1) it is deemed uncollectable, or (2) it has been classified as a loss by either our internal loan review process or external examiners. A non-collateral-dependent loan is partially charged down to its net realizable value under the same circumstances. For overdraft accounts, we generally charge them off when they exceed 60 days past due.

Acquired Loans: From time to time, we acquire loans through business acquisitions. Acquired loans are recorded at their estimated fair values at acquisition date in accordance with ASC 805 Business Combinations, factoring in credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for loan losses is not carried over or recorded for acquired loans as of the acquisition date.

The process of calculating fair values of the acquired loans, including estimates of losses that are expected to be incurred over the estimated remaining lives of the loans at acquisition date and the ongoing updates to Management's expectation of future cash flows, requires significant subjective judgments and assumptions, particularly considering

Page-55

the economic environment. The economic environment and the lack of market liquidity and transparency are factors that have influenced, and may continue to affect, these assumptions and estimates.

We estimated the fair value of acquired loans at the acquisition date based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, risk classification, fixed or variable interest rate, term of loan, whether or not the loan was amortizing, and current discount rates. Loans, except for purchased credit impaired ("PCI") loans, were grouped together according to similar risk characteristics and treated in the aggregate when applying various valuation techniques. Expected cash flows incorporated our best estimate of key assumptions at the time, such as property values, default rates, loss severity and prepayment speeds. Discount rates were based on market rates for new originations of comparable loans, where available, and included adjustments for liquidity factors.

To the extent comparable market rates were not readily available, a discount rate was derived based on the assumptions of market participants' cost of funds, servicing costs and return requirements for comparable risk assets. In either case, the discount rate did not include a factor for credit losses, as that had been considered in estimating the cash flows. The initial estimate of cash flows to be collected was derived from assumptions such as default rates, loss severities and prepayment speeds.

We acquired some loans from business combinations with evidence of significant credit quality deterioration subsequent to their origination and for which it was probable, at acquisition, that we would be unable to collect all contractually required payments. Management applied significant subjective judgment in determining which loans were PCI loans. Evidence of credit quality deterioration as of the purchase date may include data such as past due and nonaccrual status, risk grades and charge-off history. Revolving credit agreements (e.g., home equity lines of credit and revolving commercial loans) where the borrower had revolving rights at acquisition date were not considered PCI loans because the timing and amount of cash flows cannot be reasonably estimated.

According to the accounting guidance for PCI loans, the nonaccretable difference on the date of acquisition is defined as the difference between the contractually required payments and the cash flows expected to be collected, considering the result of prepayments, and is not recorded. The difference between the undiscounted expected cash flows and the fair value at acquisition date ("accretable difference") is accreted into interest income at a level yield of return over the remaining term of the loan, provided that the timing and amount of future cash flows is reasonably estimable.

For purposes of accounting for the PCI loans from past business combinations, we elected not to apply the pooling method but to account for these loans individually. Disposals of loans, which may include sales of loans to third parties, receipt of payments in full by the borrower, or foreclosure of the collateral, result in removal of the loan from the PCI loan portfolio at its carrying amount. If a PCI loan pays off earlier than expected, a gain is recorded as interest income when the payoff amount exceeds the recorded investment.

For acquired loans not considered credit impaired ("non-PCI"), we recognize the entire fair value discount accretion to interest income, based on contractual cash flows using an effective interest rate method for term loans, and on a straight line basis for revolving lines. When a non-PCI loan is placed on non-accrual status subsequent to acquisition, accretion stops until the loan is returned to accrual status. The level of accretion on non-PCI loans varies from period to period due to maturities and early pay-offs of these loans during the reporting periods. Subsequent to acquisition, if the probable and estimable losses for non-PCI loans exceed the amount of the remaining unaccreted discount, the excess is established as an allowance for loan losses. All acquired loans were acquired in acquisitions and do not represent loans purchased from third parties.

For further information regarding our acquired loans, see Note 4.

Allowance for Loan Losses is based upon estimates of loan losses and is maintained at a level considered adequate to provide for probable losses inherent in the loan portfolio. The allowance is increased by provisions for loan losses charged against earnings and reduced by charge-offs, net of recoveries.

In periodic evaluations of the adequacy of the allowance balance, Management considers current economic conditions, known and inherent risks in the portfolio, adverse situations that may affect the borrower's ability to repay, the estimated value of any underlying collateral, our past loan loss experience and other factors. The ALLL is based on estimates,

Page-56

and ultimate losses may vary from current estimates. Our Board of Directors' Asset/Liability Management Committee (“ALCO”) reviews the adequacy of the ALLL at least quarterly.

The overall allowance consists of 1) specific allowances for individually identified impaired loans ("ASC 310-10") and 2) general allowances for pools of loans ("ASC 450-20"), which incorporate changing qualitative and environmental factors (e.g., portfolio growth and trends, credit concentrations, economic and regulatory factors, etc.).

The first component, specific allowances, results from the analysis of identified problem credits and the evaluation of sources of repayment including collateral, as applicable. Through Management's ongoing loan grading and credit monitoring process, individual loans are identified that have conditions indicating the borrower may be unable to pay all amounts due in accordance with the contractual terms. These loans are evaluated for impairment individually by Management. Management considers an originated loan to be impaired when it is probable we will be unable to collect all amounts due according to the contractual terms of the loan agreement. When the fair value of the impaired loan is less than the recorded investment in the loan, the difference is recorded as impairment through the establishment of a specific allowance. For loans determined to be impaired, the extent of the impairment is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate at origination (for originated loans), based on the loan's observable market price, or based on the fair value of the collateral if the loan is collateral dependent or if foreclosure is imminent. Generally with problem credits that are collateral dependent, we obtain appraisals of the collateral at least annually. We may obtain appraisals more frequently if we believe the collateral value is subject to market volatility, if a specific event has occurred to the collateral, or if we believe foreclosure is imminent.

The estimate of cash flows expected to be collected on PCI loans is updated each quarter and requires the continued use of key assumptions and estimates. We apply judgment to develop our estimate of cash flows given the current economic environment, changes in collateral values, loan workout plans, changing probability of default, loss severities and prepayments. If we have probable decreases in cash flows expected to be collected on PCI loans, specific allowances are established to account for credit deterioration subsequent to acquisition.

The second component is an estimate of the probable inherent losses in each loan pool with similar risk characteristics. This analysis encompasses the entire loan portfolio excluding individually identified impaired loans and acquired loans whose purchase discount has not been fully accreted. Under our allowance model, loans are evaluated on a pool basis by loan segment which is further delineated by Federal regulatory reporting codes ("CALL codes"):


•	Loans secured by real estate:

- 1-4 family residential construction loans

- Other construction loans and all land development and other land loans

- Secured by farmland (including residential and other improvements)

- Revolving, open-end loans secured by 1-4 family residential properties and extended under lines of credit

- Closed-end loans secured by 1-4 family residential properties, secured by first liens

- Closed-end loans secured by 1-4 family residential properties, secured by junior liens

- Secured by multifamily (5 or more) residential properties

- Loans secured by owner-occupied non-farm nonresidential properties

- Loans secured by other non-farm nonresidential properties


•	Loans to finance agricultural production and other loans to farmers


•	Commercial and industrial loans


•	Loans to individuals for household, family and other personal expenditures (i.e., consumer loans)


•	Other loans

The model determines loan loss reserves by loan segment based on objective and subjective expected loss factors. Objective factors include an historical loss rate using a rolling twenty-quarter look-back, changes in the volume and nature of the loan portfolio, changes in credit quality metrics (past due loans, non-accrual loans, net charge-offs and adversely-graded loans), and the existence of credit concentrations. When a loan segment exceeds 100% of Tier 1 capital, additional reserves are provided due to credit concentration risk. Subjective factors include changes in the overall economic environment, legal and regulatory conditions, experience level of lending management and other relevant staff, uncertainties related to acquisitions, as well as the quality of our loan review process. The total amount allocated is determined by applying loss factors to outstanding loans by CALL code.

Page-57

For further information regarding the allowance for loan losses, see Note 4.

Allowance for Losses on Off-Balance Sheet Commitments: We make commitments to extend credit to meet the financing needs of our customers in the form of loans or standby letters of credit. We are exposed to credit loss in the event that a decline in credit quality of the borrower leads to nonperformance. We record an allowance for losses on these off-balance sheet commitments based on an estimate of probabilities of these commitments being drawn upon according to our historical utilization experience on different types of commitments and expected loss severity. This allowance is included in interest payable and other liabilities on the consolidated statements of condition.

Transfers of Financial Assets: We have entered into certain participation agreements with other organizations. We account for these transfers of financial assets as sales when control over the transferred financial assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets and liabilities have been isolated from us, (2) the transferee has the right to pledge or exchange the assets (or beneficial interests) it received, free of conditions that constrain it from taking advantage of that right, beyond a trivial benefit and (3) we do not maintain effective control over the transferred financial assets or third-party beneficial interests related to those transferred assets. No gain or loss has been recognized by us on the sale of these participation interests in 2015, 2014 and 2013.

Premises and Equipment: Premises and equipment consist of leasehold improvements, furniture, fixtures, software and equipment and are stated at cost, less accumulated depreciation and amortization, which are calculated on a straight-line basis. Furniture and fixtures are depreciated over eight years and equipment is generally depreciated over three to twenty years. Leasehold improvements are amortized over the lesser of their estimated useful lives or the terms of the leases. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation or amortization are removed from the accounts and any resulting gain or loss is recognized in income for the period. The cost of maintenance and repairs is charged to expense as incurred.

Business Combinations: Business combinations are accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations. Under the acquisition method the acquiring entity in a business combination recognizes the acquired assets and assumed liabilities at their estimated fair values as of the date of acquisition. Any excess of the purchase price over the fair value of net assets and other identifiable intangible assets acquired is recorded as goodwill. To the extent the fair value of net assets acquired, including other identifiable assets, exceed the purchase price, a bargain purchase gain is recognized. Assets acquired and liabilities assumed from contingencies must also be recognized at fair value, if the fair value can be determined during the measurement period. Results of operations of an acquired business are included in the statement of operations from the date of acquisition. Acquisition-related costs, including conversion and restructuring charges, are expensed as incurred.

Goodwill and Other Intangible Assets: Goodwill is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill that arises from a business combination determined to have an indefinite useful life is not amortized, but is periodically evaluated for impairment at the reporting unit level, at least annually. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangible represents estimated future benefit of deposits related to an acquisition and is booked separately from the related deposits and is evaluated periodically for impairment. The core deposit intangible asset is amortized on an accelerated method over its estimated useful life of ten years.

We make a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit where goodwill is assigned is less than its carrying amount before applying a two-step goodwill impairment test. If we conclude that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, we do not perform the two-step impairment test. Goodwill is tested for impairment on an interim basis if circumstances change or an event occurs between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying amount. The qualitative assessment includes adverse events or circumstances identified that could negatively affect the reporting units’ fair value as well as positive and mitigating events. Such indicators may include, among others, a significant change in legal factors or in the general business climate, significant change in our stock price and market capitalization, unanticipated competition, and an action or assessment by a regulator.

Other Real Estate Owned ("OREO"): OREO is comprised of property acquired through foreclosure, in substance repossession or acceptance of deeds-in-lieu of foreclosure when the related loan receivable is de-recognized. OREO is recorded at fair value of the collateral less estimated costs to sell, establishing a new cost basis, and subsequently accounted for at the lower of cost or fair value less estimated costs to sell. Any shortfall of collateral value from the recorded investment of the related loan is recognized as loss at the time of foreclosure and is charged against the allowance for loan losses. Fair value of collateral is generally based on an independent appraisal of the property. Revenues and expenses associated with OREO, and subsequent adjustments to the fair value of the property and to the estimated costs of disposal, are realized and reported as a component of non-interest income and expense when incurred.

Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key current and former officers. Bank owned life insurance ("BOLI") is recorded in interest receivable and other assets on the consolidated statements of condition at the amount that can be realized under the insurance contract at the period end, which is the cash surrender value adjusted for other charges or amounts due that are probable at settlement.

Federal Home Loan Bank of San Francisco ("FHLB") Stock: The Bank is a member of the FHLB. Members are required to own a certain amount of stock based on the level of borrowings and other factors. Our investment in FHLB stock is carried at cost and is included as part of interest receivable and other assets on the consolidated statements of condition. We periodically evaluate FHLB stock for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as non-interest income.

Investments in Low Income Housing Tax Credit Funds: We have invested in limited partnerships that were formed to develop and operate affordable housing projects for low or moderate income tenants throughout California. Our ownership in each limited partnership is less than two percent. In accordance with ASU No. 2014-01, Investments - Equity Method and Joint Ventures (Topic 323), we elected to account for the investments in qualified affordable housing tax credit funds using the proportional amortization method. Under the proportional amortization method, the initial cost of the investment is amortized in proportion to the tax credits and other tax benefits received and the net investment performance is recognized as part of income tax expense (benefit). Each of the partnerships must meet the regulatory minimum requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits. If the partnerships cease to qualify during the compliance period, the credit may be denied for any period in which the project is not in compliance and a portion of the credit previously taken is subject to recapture with interest.

Employee Stock Ownership Plan (“ESOP”): We recognize compensation cost of the ESOP contribution when funds become committed for the purchase of Bancorp's common shares into the ESOP in the year in which the employees render service entitling them to the contribution. If we contribute stock, the compensation cost is the fair value of the shares when they are committed to be released, i.e. when the number of shares becomes known. During 2015, 2014 and 2013, the Bank only made cash contributions to the ESOP without leveraging.

Income Taxes: Income taxes reported in the consolidated financial statements are computed based on an asset and liability approach. We recognize the amount of taxes payable or refundable for the current year and we record deferred tax assets and liabilities for future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the temporary differences are expected to reverse. We record net deferred tax assets to the extent it is more likely than not that they will be realized. In evaluating our ability to recover the deferred tax assets and the need to establish a valuation allowance against the deferred tax assets, Management considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. In projecting future taxable income, Management develops assumptions including the amount of future state and federal pretax operating income, the reversal of temporary differences, and the implementation of feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates being used to manage the underlying business. Bancorp files consolidated federal and combined state income tax returns.

We recognize the financial statement effect of a tax position when it is more likely than not, based on the technical merits and all available evidence, that the position will be sustained upon examination, including the resolution through protests, appeals or litigation processes. For tax positions that meet the more-likely-than-not threshold, we measure and record the largest amount of tax benefit that is greater than fifty percent likely of being realized upon ultimate settlement with the taxing authority. The remainder of the benefits associated with tax positions taken is recorded as

Page-59

unrecognized tax benefits, along with any related interest and penalties. Interest and penalties related to unrecognized tax benefits are recorded in tax expense.

In deciding whether or not our tax positions taken meet the more-likely-than-not recognition threshold, we must make judgments and interpretations about the application of inherently complex state and federal tax laws. To the extent tax authorities disagree with tax positions taken by us, our effective tax rates could be materially affected in the period of settlement with the taxing authorities. Revision of our estimate of accrued income taxes also may result from our own income tax planning, which may affect effective tax rates and results of operations for any reporting period.

We present an unrecognized tax benefit as a reduction of a deferred tax asset for a net operating loss ("NOL") carryforward, or similar tax loss or tax credit carryforward, rather than as a liability, when (1) the uncertain tax position would reduce the NOL or other carryforward under the tax law of the applicable jurisdiction and (2) we intend to and are able to use the deferred tax asset for that purpose. Otherwise, the unrecognized tax benefit is presented as a liability instead of being netted with deferred tax assets.

Earnings per share (“EPS”) are based upon the weighted average number of common shares outstanding during each year. The following table shows: 1) weighted average basic shares, 2) potentially dilutive weighted average common shares related to stock options, unvested restricted stock awards and stock warrant, and 3) weighted average diluted shares. Basic 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 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. We have two forms of our 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. Therefore, under the two-class method, the difference in EPS is not significant for these participating securities.

Share-Based Compensation: All share-based payments granted subsequent to January 1, 2006, including stock options and restricted stock, are recognized as stock-based compensation expense in the statements of comprehensive income based on the grant-date fair value of the award with a corresponding increase in common stock. The grant-date fair value of the award is amortized on a straight-line basis over the requisite service period, which is generally the vesting period. The stock-based compensation expense excludes stock grants to directors as compensation for their services, which are recognized as director expenses separately based on the grant-date value of the stock. See Note 9 for further discussion.

We determine fair value of stock options at grant date using the Black-Scholes pricing model that takes into account the stock price at the grant date, the exercise price, the expected life of the option, the volatility of the underlying stock, the expected dividend yield and the risk-free interest rate over the expected life of the option. The Black-Scholes option valuation model requires the input of highly subjective assumptions, including the expected life of the stock-

Page-60

based award and stock price volatility. The assumptions used represent Management's best estimates based on historical information, but these estimates involve inherent uncertainties and the application of Management's judgment. As a result, if other assumptions had been used, the recorded stock-based compensation expense could have been materially different from that recorded in the consolidated financial statements. In addition, we are required to estimate the expected forfeiture rates. If our actual forfeiture rate is materially different from the estimate, the share-based compensation expense could be materially different. Fair value of restricted stock is based on the stock price on grant date.

Derivative Financial Instruments and Hedging Activities

Fair Value Hedges: All of our interest rate swap contracts are designated and qualified as fair value hedges. We apply shortcut hedge accounting for one of our interest rate swap contracts, as it is structured to mirror all of the provisions of the hedged loan agreement. This interest rate swap is carried on the consolidated statements of condition at its fair value in other assets (when the fair value is positive) or in other liabilities (when the fair value is negative). The change in the fair value of the interest rate swap is recorded in non-interest income. As a result of interest rate fluctuations, the hedged fixed-rate loan also gains or loses value. The unrealized gain or loss resulting from the change in fair value of the hedged-loan is recorded as an adjustment to the hedged loan and offset in non-interest income. Under shortcut hedge accounting treatment, the change in fair value of the interest rate swap is deemed perfectly offset by the change in fair value of the hedged loan, resulting in zero impact to net income.

The six remaining interest rate swap contracts are accounted for using non-shortcut hedge accounting treatment. The interest rate swaps are closely aligned to the terms of the designated fixed-rate loans. The hedging relationships are tested for effectiveness on a quarterly basis. The interest rate swaps are carried on the consolidated statements of condition at their fair value in other assets (when the fair value is positive) or in other liabilities (when the fair value is negative). The changes in the fair value of the interest rate swaps are recorded in interest income. The unrealized gains or losses due to changes in fair value of the hedged fixed-rate loans are recorded as an adjustment to the hedged loans and offset in interest income. For derivative instruments executed with the same counterparty under a master netting arrangement, we do not offset fair value amounts of interest rate swaps in liability position with the ones in asset position. For further detail, see Note 15.

Advertising Costs are expensed as incurred. For the years ended December 31, 2015, 2014, and 2013, advertising costs totaled $334 thousand, $400 thousand, and $490 thousand, respectively.

Comprehensive Income includes net income and changes in the unrealized gain or loss of available-for-sale investment securities, net of related taxes, reported on the statements of comprehensive income and as components of stockholders' equity.

Fair Value Measurements: We use fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. We base our fair values on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Securities available-for-sale and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record certain assets at fair value on a non-recurring basis, such as purchased loans recorded at acquisition date, certain impaired loans, other real estate owned and securities held-to-maturity that are other-than-temporarily impaired. These non-recurring fair value adjustments typically involve write-downs of individual assets due to application of lower-of-cost or market accounting.

When we develop our fair value measurement process, we maximize the use of observable inputs. Whenever there is no readily available market data, we use our best estimates and assumptions in determining fair value, but these estimates involve inherent uncertainties and the application of Management's judgment. As a result, if other assumptions had been used, our recorded earnings or disclosures could have been materially different from those reflected in these financial statements.

For detailed information on our use of fair value measurements and our related valuation methodologies, see Note 10.

Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent amounts of revenues and expenses during the reporting

Page-61

period. Actual results could differ from those estimates. Significant accounting estimates reflected in the consolidated financial statements include ALLL, other-than-temporary impairment of investment securities, accrued liabilities, accounting for income taxes and fair value measurements (including fair values of acquired assets and assumed liabilities at acquisition dates) as discussed in the Notes herein.

Recently Adopted and Issued Accounting Standards

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU is a converged standard involving FASB and International Financial Reporting Standards that provides a single comprehensive revenue recognition model for all contracts with customers across transactions and industries. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount and at a time that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) Deferral of the Effective Date which institutes a one-year deferral of the effective date of this amendment to annual reporting periods beginning after December 15, 2017. We are currently evaluating the provisions of this ASU and will be monitoring developments and additional guidance to determine the potential outcome the new standard will have on our financial condition and results of operations.

In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation (Topic 718) Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. This ASU provides guidance for entities that grant their employees share-based payment awards where a performance target that affects vesting could be achieved after the requisite service period. That is the case when an employee is eligible to retire or otherwise terminate employment before the end of the period in which a performance target could be achieved and still be eligible to vest in the award if and when the performance target is achieved. This ASU stipulates that compensation expense should be recognized in the period where the performance target becomes probable of being achieved as opposed to the date that the award was granted. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. We do not expect this ASU to have a material impact on our financial condition or results of operations.

In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. The amendments in this ASU provide guidance about a customer's accounting for fees paid in a cloud computing arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, then the customer should account for the arrangement as a service contract. The two criteria that must be met to be considered a software license are: 1) the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty; and 2) it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. ASU 2015-05 is effective for annual periods, including interim periods within those annual periods beginning after December 15, 2015. We do not expect this ASU to have a material impact on our financial condition or results of operations.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805) Simplifying the Accounting for Measurement-Period Adjustments. The amendments in this ASU require that an acquirer recognize adjustments to estimated amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Prior to the amendments, an acquirer was required to retrospectively adjust the provisional amounts recognized at the acquisition date with a corresponding adjustment to goodwill. ASU 2015-16 is effective for public business entities for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. We do not expect this ASU to have a material impact on our financial condition or results of operations.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this ASU make improvements to GAAP related to financial instruments that include the following as applicable to us.


•	Equity investments, except for those accounted for under the equity method of accounting or those that result in consolidation of the investee, are required to be measured at fair value with changes in fair value recognized

Page-62

in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer.


•	Simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment - if impairment exists, this requires measuring the investment at fair value.


•	Eliminates the requirement for public companies to disclose the method(s) and significant assumptions used to estimate the fair value that is currently required to be disclosed for financial instruments measured at amortized cost on the balance sheet.


•	Public companies will be required to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes.


•	Requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements.


•	The reporting entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity's other deferred tax assets.

ASU 2016-01 is effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This ASU will impact our financial statement disclosures, however, we do not expect this ASU to have a material impact on our financial condition or results of operations.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This ASU was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities, including leases classified as operating leases under previous GAAP, on the balance sheet and requiring additional disclosures of key information about leasing arrangements. ASU 2016-02 is effective for annual periods, including interim periods within those annual periods beginning after December 15, 2018 and requires a modified retrospective approach to adoption. Early application of the amendments is permitted. We are currently evaluating the provisions of this ASU and will be monitoring developments and additional guidance to determine the potential outcome the amendments will have on our financial condition and results of operations.

Note 2: Acquisition

On November 29, 2013, we completed the acquisition of NorCal, parent company of Bank of Alameda, to enhance our market presence. The acquisition added $173.8 million in loans, $241.0 million in deposits and $53.7 million in investment securities to Bank of Marin as well as four branch offices serving Alameda, Emeryville, and Oakland. Effective October 31, 2014, the Emeryville branch was closed after Management determined that our customers and the business community can be easily supported from our Oakland location. The assets acquired and liabilities assumed, both tangible and intangible, were recorded at their fair values as of the acquisition date in accordance with ASC 805, Business Combinations. The acquisition was treated as a "reorganization" within the definition of section 368(a) of the Internal Revenue Code and is generally considered tax-free for U.S. federal income tax purposes.

Goodwill

As a result of the NorCal Acquisition, we recorded $6.4 million in goodwill, which represents the excess of the total purchase price paid over the fair value of the assets acquired, net of the fair values of liabilities assumed. Goodwill mainly reflects expected value created through the combined operations of Bank of Alameda and Bank of Marin and our expanded footprint in the East Bay. At December 31, 2015 and 2014, we determined that the fair value of our traditional community banking activities (provided through our branch network) exceeded the carrying amount. Therefore, no impairment on goodwill has been recorded. The goodwill is not deductible for tax purposes.

Core Deposit Intangible

The core deposit intangible represents the estimated future benefits of acquired deposits and is booked separately from the related deposits. The value of the core deposit intangible asset was determined using a discounted cash flow approach to arrive at the cost differential between the core deposits (non-maturity deposits such as transaction, savings and money market accounts) and alternative funding sources. It was calculated as the present value of the difference in cash flows between maintaining the core deposits (interest and net maintenance costs) and the cost of an equal amount of funds with a similar term from an alternative source. The core deposit intangible is amortized on an accelerated basis over an estimated ten-year life, and it is evaluated periodically for impairment. No impairment loss was recognized in 2015 or 2014.

We recorded a core deposit intangible asset of $4.6 million at acquisition, of which $69 thousand was amortized in 2013, $771 thousand was amortized in 2014 and $619 thousand was amortized in 2015. At December 31, 2015, the future estimated amortization expense is as follows:



(in thousands)	2016		2017		2018		2019		2020		Thereafter		Total
Core deposit intangible amortization	$	533	$	472	$	413	$	388	$	365	$	942	$	3,113

Pro Forma Results of Operations

The contribution of the acquired operations of the former NorCal Community Bancorp to our results of operations for the period November 29 to December 31, 2013 is as follows: interest income of $1.1 million, interest expense of $68 thousand, non-interest income of $95 thousand, non-interest expense of $1.1 million and income before income taxes of $109 thousand. These amounts include acquisition-related costs, accretion of the discount on the acquired loans, amortization of the fair value mark on time deposits, core deposit intangible amortization, and subordinated debentures amortization. NorCal Community Bancorp's results of operations prior to the acquisition date are not included in our operating results for 2013.

The following table presents NorCal Community Bancorp's revenue (interest income and non-interest income) and earnings included in our consolidated statement of comprehensive income for the year ended December 31, 2013. This pro forma information does not necessarily reflect the results of operations that would have resulted had the acquisition been completed on January 1, 2013, nor is it indicative of the results of operations in future periods.

Investment securities carried at $87.9 million and $74.7 million at December 31, 2015 and 2014, respectively, were pledged with the State of California: $87.1 million and $73.8 million to secure public deposits in compliance with the Local Agency Security Program, and $840 thousand and $856 thousand to provide collateral for trust deposits. In addition, investment securities carried at $1.1 million were pledged to collateralize an internal Wealth Management and Trust Services (“WMTS”) checking account at both December 31, 2015 and 2014.

Other-Than-Temporarily Impaired ("OTTI") Debt Securities

We have evaluated the credit ratings of our investment securities and their issuers and/or insurers. Based on our evaluation, Management has determined that no investment security in our investment portfolio is other-than-temporarily impaired as of December 31, 2015. We do not have the intent, and it is more likely than not that we will not have to sell the remaining securities temporarily impaired at December 31, 2015 before recovery of the amortized cost basis.

As of December 31, 2015, there were six investment positions that had been in a continuous loss position for 12 months or more. These securities consisted of a debenture of government-sponsored agency, an obligation of U.S. state and political subdivisions, one corporate bond and three CMOs. We have evaluated each of the securities and believe that the decline in fair value is primarily driven by factors other than credit. It is probable that we will be able to collect all amounts due according to the contractual terms and no other-than-temporary impairment exists on these securities. The CMOs issued by FNMA, FHLMC and GNMA are supported by the U.S. Federal Government to protect us from credit losses. Additionally, the obligation of state and political subdivisions was deemed creditworthy based on our review of the issuer's recent financial information. The corporate bond subsequently matured and paid off in February 2016.

Forty-eight investment securities in our portfolio were in a temporary loss position for less than twelve months as of December 31, 2015. They consisted of obligations of U.S. state and political subdivisions, corporate bonds, MBS, CMOs, and debentures of government-sponsored agencies. We determine that the strengths of GNMA and FNMA through guarantee or support from the U.S. Federal Government are sufficient to protect us from credit losses. Other temporarily impaired securities are deemed creditworthy after credit analysis. Additionally, all are rated as investment grade by at least one major rating agency. We concluded that these securities were not other-than-temporarily impaired at December 31, 2015.

Non-Marketable Securities

As a member of the FHLB, we are required to maintain a minimum investment in the FHLB capital stock determined by the Board of Directors of the FHLB. Investment requirements can increase in the event we increase our borrowings with the FHLB. Shares cannot be purchased or sold except between the FHLB and its members at $100 per share par value. We held $8.4 million and $8.2 million of FHLB stock recorded at cost in other assets at December 31, 2015 and 2014, respectively. 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. Management does not believe that the FHLB stock is other-than-temporarily-impaired, as we expect to be able to redeem it at cost. On February 18, 2016, the FHLB announced a cash dividend for the fourth quarter of 2015 at an annualized dividend rate of 7.99% to be distributed in mid-March 2016.

As a member bank of Visa U.S.A., we hold 16,939 shares of Visa Inc. Class B common stock with a carrying value of zero, which is equal to our cost basis. These shares are restricted from resale until their conversion into Class A (voting) shares upon the termination of Visa Inc.'s Covered Litigation escrow account. As a result of the restriction, these shares are not considered available-for-sale and are not carried at fair value. Converting this Class B common stock to Class A common stock at a conversion rate of 1.6483, the value would be $2.2 million and $1.8 million at December 31, 2015 and 2014, respectively. The conversion rate is subject to further reduction upon the final settlement of the covered litigation against Visa Inc. and its member banks. See Note 13 herein.

We invest in low income housing tax credit funds as a limited partner, which totaled $2.7 million and $1.8 million recorded in other assets as of December 31, 2015 and 2014, respectively. Beginning 2014, we have elected to account for all low income housing investments using the proportional amortization method instead of the cost method. In 2015, we recognized $225 thousand of low income housing tax credits and other tax benefits, net of $174 thousand of amortization expense of low income housing tax credit investment, as a component of income tax expense for 2015. As of December 31, 2015, our unfunded commitments for these low income housing tax credit funds totaled $1.7 million. We did not recognize any impairment losses on these low income housing tax credit investments during 2015, 2014 or 2013.

Credit Quality of Loans

Virtually all of our loans are generated from customers located in California, primarily in the counties of Marin, Alameda, Sonoma, San Francisco and Napa. Approximately 85% and 87% at December 31, 2015 and 2014, respectively, of total loans were secured by real estate, while 2% were unsecured at both December 31, 2015 and 2014. At December 31, 2015, 66% of our loans were for commercial real estate, 83% of which were secured by real estate located in Marin, Sonoma, Alameda, San Francisco and Napa counties (California).

Outstanding loans by class and payment aging as of December 31, 2015 and 2014 are as follows:

¹ Our residential loan portfolio includes no sub-prime loans, nor is it our normal practice to underwrite loans commonly referred to as "Alt-A mortgages," the characteristics of which are loans lacking full documentation, borrowers having low FICO scores or higher loan-to-value ratios.

² Amounts include $1 thousand and $1.4 million of Purchased Credit Impaired ("PCI") loans that have stopped accreting interest at December 31, 2015 and 2014, respectively. Amounts exclude accreting PCI loans of $3.7 million and $3.8 million at December 31, 2015 and 2014, respectively, as we have a reasonable expectation about future cash flows to be collected and we continue to recognize accretable yield on these loans in interest income. There were no accruing loans past due more than ninety days at December 31, 2015 or 2014.

³ Amounts included deferred loan origination costs, net of deferred loan origination fees, of $768 thousand and $487 thousand at December 31, 2015 and 2014, respectively. Amounts were also net of unaccreted purchase discounts on non-PCI loans of $3.2 million and $4.4 million at December 31, 2015 and 2014, respectively.

Our 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/or 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/or 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/or inventory, and typically include a personal guarantee. We target stable businesses with guarantors that have proven to be resilient in periods of economic stress. Typically, the guarantors provide an additional source of repayment for most of our credit extensions.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans discussed above. We underwrite these loans to be repaid from cash flow and to be 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, substantially all of our loans are guaranteed by the owners of the properties. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. In the event of a vacancy, guarantors are expected to carry the loans until a replacement tenant can be found. 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.

Page-70

Construction loans are generally made to developers and builders to finance construction, renovation and occasionally land acquisitions. These loans are underwritten after evaluation of the borrower's financial strength, reputation, prior track record, and independent appraisals. The construction industry can be affected by significant events, 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 primarily consist of home equity lines of credit, other residential (tenancy-in-common, or “TIC”) loans, and installment and other consumer loans. We originate consumer loans utilizing credit score information, debt-to-income ratio and loan-to-value ratio analysis. Diversification, coupled with relatively small loan amounts that are spread across many individual borrowers, mitigates risk. Additionally, trend reports are reviewed by Management on a regular basis. Our residential loan portfolio includes TIC units almost entirely in San Francisco. These loans tend to have more equity in their properties than conventional residential mortgages, which mitigates risk. Installment and other consumer loans include mostly loans for floating homes and mobile homes along with a small number of installment loans.

We use a risk rating system to evaluate asset quality, and to identify and monitor credit risk in individual loans, and ultimately in the portfolio. Definitions of loans that are risk graded “Special Mention” or worse are consistent with those used by the Federal Deposit Insurance Corporation ("FDIC"). Our internally assigned grades are as follows:

Pass: Loans to borrowers of acceptable or better credit quality. Borrowers in this category demonstrate fundamentally sound financial positions, repayment capacity, credit history and management expertise. Loans in this category must have an identifiable and stable source of repayment and meet the Bank’s policy regarding debt service coverage ratios. These borrowers are capable of sustaining normal economic, market or operational setbacks without significant financial consequences. Negative external industry factors are generally not present. The loan may be secured, unsecured or supported by non-real estate collateral for which the value is more difficult to determine and/or marketability is more uncertain. This category also includes “Watch” loans, where the primary source of repayment has been delayed. “Watch” is intended to be a transitional grade, with either an upgrade or downgrade within a reasonable period.

Special Mention: Potential weaknesses that deserve close attention. If left uncorrected, those potential weaknesses may result in deterioration of the payment prospects for the asset. Special Mention assets do not present sufficient risk to warrant adverse classification.

Substandard: Inadequately protected by either the current sound worth and paying capacity of the obligor or the collateral pledged, if any. A Substandard asset has a well-defined weakness or weaknesses that jeopardize(s) the liquidation of the debt. Substandard assets are characterized by the distinct possibility that we will sustain some loss if such weaknesses or deficiencies are not corrected. Well-defined weaknesses include adverse trends or developments of the borrower’s financial condition, managerial weaknesses and/or significant collateral deficiencies.

Doubtful: Critical weaknesses that make collection or liquidation in full improbable. There may be specific pending events that work to strengthen the asset; however, the amount or timing of the loss may not be determinable. Pending events generally occur within one year of the asset being classified as Doubtful. Examples include: merger, acquisition, or liquidation; capital injection; guarantee; perfecting liens on additional collateral; and refinancing. Such loans are placed on non-accrual status and usually are collateral-dependent.

We regularly review our credits for accuracy of risk grades whenever new information is received. Borrowers are required to submit financial information at regular intervals:


•	Generally, 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.


•	Investor commercial real estate borrowers are generally required to submit rent rolls or property income statements at least annually.


•	Construction loans are monitored monthly, and reviewed on an ongoing basis.


•	Home equity and other consumer loans are reviewed based on delinquency.


•	Loans graded “Watch” or more severe, regardless of loan type, are reviewed no less than quarterly.

Troubled Debt Restructuring

Our loan portfolio includes certain loans that have been modified in a troubled debt restructuring (“TDR”), where economic concessions have been granted to borrowers experiencing financial difficulties. These concessions typically result from our loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions. TDRs on non-accrual status at the time of restructure may be returned to accruing status after Management considers the borrower’s sustained repayment performance for a reasonable period, generally six months, and obtains reasonable assurance of repayment and performance.

A loan may no longer be reported as a TDR if all of the following conditions are met:


•	The loan is subsequently refinanced or restructured at current market interest rates and the new terms are consistent with the treatment of creditworthy borrowers under regular underwriting standards;


•	The borrower is no longer considered to be in financial difficulty;


•	Performance on the loan is reasonably assured; and;


•	Existing loan did not have any forgiveness of principal or interest.

The removal of TDR status must be approved by the same management level that approved the upgrading of the loan classification.

During 2015, five loans with a recorded investment totaling $1.6 million were removed from TDR designation. There were no loans removed from TDR designation during 2014.

Page-72

The table below summarizes outstanding TDR loans by loan class as of December 31, 2015 and December 31, 2014. The summary includes both TDRs that are on non-accrual status and those that continue to accrue interest.

Management monitors delinquent loans continuously and identifies problem loans, generally loans graded substandard or worse, to be evaluated individually for impairment testing. Generally, the recorded investment in impaired loans is net of any charge-offs from estimated losses related to specifically-identified impaired loans when they are deemed uncollectible. The charged-off portion of impaired loans outstanding at December 31, 2015 and 2014 totaled approximately $2.1 million and $5.5 million, respectively. In addition, the recorded investment in impaired loans is net of purchase discounts or premiums on acquired loans. At December 31, 2015 and 2014, outstanding commitments to extend credit on impaired loans, including performing loans to borrowers whose terms have been modified in TDRs, totaled $1.3 million and $1.4 million, respectively.

Purchased Credit-Impaired Loans

We evaluated loans purchased in acquisitions in accordance with accounting guidance in ASC 310-30 related to loans acquired with deteriorated credit quality. Acquired loans are considered credit-impaired if there is evidence of significant deterioration of credit quality since origination and it is probable, at the acquisition date, that we will be unable to collect all contractually required payments receivable. Management has determined certain loans purchased in our two acquisitions to be PCI loans based on credit indicators such as nonaccrual status, past due status, loan risk grade, loan-to-value ratio, etc. Revolving credit agreements (e.g., home equity lines of credit and revolving commercial loans) are not considered PCI loans as cash flows cannot be reasonably estimated.

For acquired loans not considered credit-impaired, the difference between the contractual amounts due (principal amount) and the fair value is accounted for subsequently through accretion. We recognize discount accretion based on the acquired loan’s contractual cash flows using an effective interest rate method. The accretion is recognized through the net interest margin.

The following table presents the fair value of purchased credit-impaired and other loans acquired from Bank of Alameda as of the acquisition date:



	November 29, 2013
(in thousands)	Purchased credit-impaired loans			Other purchased loans			Total
Contractually required payments including interest	$	5,706		$	211,769		$	217,475
Less: nonaccretable difference	(1,183		)	—			(1,183		)
Cash flows expected to be collected (undiscounted)	4,523			211,769			216,292
Accretable yield	(707		)	(41,826		)	(42,533		)
Fair value of purchased loans	$	3,816		$	169,943		$	173,759

¹ $6.6 million of the $41.8 million represents the difference between the contractual principal amounts due and the fair value. This discount is to be accreted to interest income over the remaining lives of the loans. The remaining $35.2 million is the contractual interest to be earned over the life of the loans.

The following table reflects the outstanding balance and related carrying value of PCI loans as of the acquisition date:

Page-76



	November 29, 2013
PCI Loans (in thousands)	Unpaid principal balance		Fair value
Commercial and industrial	$	847	$	369
Commercial real estate	3,757		3,362
Construction	150		16
Home equity	239		69
Total purchased credit-impaired loans	$	4,993	$	3,816

For the PCI loans, the accretable yield initially represents the excess of the cash flows expected to be collected at acquisition over the fair value of the loans at the acquisition date, and is accreted into interest income over the estimated remaining life of the purchased credit-impaired loans using the effective yield method, provided that the timing and amount of future cash flows is reasonably estimable. The accretable yield is affected by:


•	Changes in interest rate indices for variable rate loans – Expected future cash flows are based on the variable rates in effect at the time of the regular evaluations of cash flows expected to be collected;


•	Changes in prepayment assumptions – Prepayments affect the estimated life of the loans which may change the amount of interest income, and possibly principal, expected to be collected; and


•	Changes in the expected principal and interest payments over the estimated life – Updates to expected cash flows are driven by the credit outlook and actions taken with borrowers. Changes in expected future cash flows from loan modifications are included in the regular evaluations of cash flows expected to be collected.

The cash flows expected to be collected are updated each quarter based on current assumptions regarding default rates, loss severities, and other factors that are reflective of current market conditions. Probable decreases in expected cash flows after acquisition result in the recognition of impairment as a specific allowance for loan losses or a charge-off to the allowance. The increase of specific allowance for PCI loan losses amounted to $4 thousand, $3 thousand and $203 thousand during 2015, 2014 and 2013 respectively. Probable and significant increases in expected cash flows would first reverse any related allowance for loan losses and any remaining increases would be recognized prospectively as interest income over the estimated remaining lives of the loans. During 2015, 2014 and 2013, the amount of reduction in the allowance for loan losses established for PCI loans due to the increase in the present value of cash flows expected to be collected was $2 thousand, $238 thousand and $237 thousand, respectively.

The nonaccretable difference represents the difference between the undiscounted contractual cash flows and the undiscounted expected cash flows, and also reflects the estimated credit losses in the acquired loan portfolio at the acquisition date and can fluctuate due to changes in expected cash flows during the life of the PCI loans.

The following table reflects the outstanding balance and related carrying value of PCI loans related to the 2013 NorCal acquisition and the 2011 Charter Oak acquisition as of December 31, 2015 and 2014:



	December 31, 2015				December 31, 2014

Total purchased credit-impaired loans	$	4,977	$	3,681	$	7,678	$	5,192

Pledged Loans

Our FHLB line of credit is secured under terms of a blanket collateral agreement by a pledge of certain qualifying loans with an unpaid principal balance of $833.8 million and $868.1 million at December 31, 2015 and 2014, respectively. In addition, we pledge a certain residential loan portfolio, which totaled $45.2 million and $27.7 million at December 31, 2015 and 2014, respectively, to secure our borrowing capacity with the Federal Reserve Bank (“FRB”). Also see Note 8 below.

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 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.

An analysis of net loans to related parties for each of the three years ended December 31, 2015, 2014 and 2013 is as follows:

We have purchased life insurance policies on the lives of certain officers designated by the Board of Directors to finance employee benefit programs as of December 31, 2015. Death benefits provided under the specific terms of these programs are estimated to be $64.1 million at December 31, 2015 and the benefits to employees' beneficiaries are limited to the employee's active service period. The investment in bank owned life insurance policies are reported in interest receivable and other assets at their cash surrender value of $29.5 million and $28.6 million at December 31, 2015 and December 31, 2014, respectively. The cash surrender value includes both the original premiums paid for the life insurance policies and the accumulated accretion of policy income since inception of the policies. Income of $814 thousand, $841 thousand and $954 thousand was recognized on the life insurance policies in 2015, 2014 and 2013, respectively. 2013 BOLI income includes a $228 thousand benefit realized on the death of an insured employee. We regularly monitor the credit ratings of our insurance carriers to ensure that they are in compliance with our policy.

Note 7: Deposits

A stratification of time deposits at December 31, 2015 and 2014 is presented in the following table:



(in thousands)	December 31, 2015		December 31, 2014
Time deposits of less than $100 thousand	$	39,534	$	44,130
Time deposits of $100 thousand to $250 thousand	67,352		58,240
Time deposits of more than $250 thousand	54,571		47,344
Total time deposits	$	161,457	$	149,714

Interest on time deposits was $853 thousand, $917 thousand and $922 thousand in 2015, 2014 and 2013, respectively.

Scheduled maturities of time deposits at December 31, 2015 are presented as follows:



(in thousands)	2016		2017		2018		2019		2020		Thereafter		Total
Scheduled maturities of time deposits	$	113,232	$	23,482	$	9,317	$	7,482	$	7,944	$	—	$	161,457

As of December 31, 2015, $50.9 million in securities held-to-maturity and $36.2 million securities available-for-sale were pledged as collateral for our local agency deposits.

Our deposit portfolio includes deposits offered through the Promontory Interfinancial Network that are comprised of Certificate of Deposit Account Registry Service^® ("CDARS") balances included in time deposits and Insured Cash Sweep^® ("ICS") balances included in money market deposits. Through this network, we are able to offer our customers access to FDIC-insured deposit products in aggregate amounts exceeding current insurance limits. When we place funds through CDARSand ICS on behalf of a customer, we typically receive matching deposits through the network's reciprocal deposit program. We consider the reciprocal deposits to be in-market deposits as distinguished from traditional out-of-market brokered deposits. We also have the ability to place deposits through the network for which we receive no matching deposits. At December 31, 2015, we had $14.3 million in CDARS and $12.2 million in ICS balances in the reciprocal deposit program. At December 31, 2014, we had no CDARS or ICS deposits in the reciprocal deposit program. At December 31, 2015 and 2014 we had placed $355 thousand and $18.3 million, respectively, in CDARS deposits for which we received no matching deposits.

The aggregate amount of deposit overdrafts that have been reclassified as loan balances was $84 thousand and $380 thousand at December 31, 2015 and 2014, respectively. Collectability of these overdrafts is subject to the same credit review process as other loans.

The Bank accepts deposits from shareholders, directors and employees in the normal course of business, and the terms are comparable to those with non-affiliated parties. The total deposits from directors and their businesses, and executive officers were $8.3 million and $8.8 million at December 31, 2015 and 2014, respectively.

Note 8: Borrowings

Federal Funds Purchased – We had unsecured lines of credit totaling $92.0 million and $72.0 million with correspondent banks for overnight borrowings at December 31, 2015 and 2014, respectively. In general, interest rates on these lines approximate the federal funds target rate. At December 31, 2015 and December 31, 2014, we had no overnight borrowings outstanding under these credit facilities.

Federal Home Loan Bank Borrowings – As of December 31, 2015 and 2014, we had lines of credit with the FHLB totaling $470.6 million and $450.6 million, respectively, based on asset size and eligible collateral of certain loans. At December 31, 2015, FHLB overnight borrowings totaled $52.0 million at a rate of 0.27%. At December 31, 2014, there were no FHLB overnight borrowings.

On February 5, 2008, we entered into a ten-year borrowing agreement under the same FHLB line of credit for $15.0 million at a fixed rate of 2.07%, which remained outstanding at December 31, 2015. Interest-only payments are required every three months until the entire principal is due on February 5, 2018. The FHLB has the unconditional right to accelerate the due date on May 5, 2016 and every three months thereafter (the “put dates”). If the FHLB exercises its right to accelerate the due date, the FHLB will offer replacement funding at the current market rate, subject to certain conditions. We must comply with the put date, but are not required to accept replacement funding.

At December 31, 2015 and 2014, $403.4 million and $435.3 million, respectively, was remaining as available for borrowing from the FHLB, net of the overnight borrowings, term borrowings, and an unused standby letter of credit totaling $241 thousand.

Federal Reserve Line of Credit – The Bank has a line of credit with the Federal Reserve Bank ("FRB") secured by certain residential loans. At December 31, 2015 and 2014, the Bank had borrowing capacity under this line totaling $37.8 million and $27.7 million, respectively, and had no outstanding borrowings with the FRB.

As part of the NorCal Acquisition, Bancorp assumed two subordinated debentures due to NorCal Community Bancorp Trusts I and II (the "Trusts"), established for the sole purpose of issuing trust preferred securities on September 22, 2003 and December 29, 2005, respectively. The subordinated debentures were recorded at fair values totaling $4.95 million at acquisition date with contractual values totaling $8.2 million. The difference between the contractual balance and the fair value at acquisition date is accreted into interest expense over the lives of the debentures. Accretion on the subordinated debentures totaled $210 thousand, $216 thousand and $19 thousand in 2015, 2014 and 2013, respectively. Bancorp has the option to defer payment of the interest on the subordinated debentures for a period of up to five years, as long as there is no default on the subordinated debentures. In the event of interest deferral, dividends to Bancorp common stockholders are prohibited. The trust preferred securities were sold and issued in private transactions pursuant to an exemption from registration under the Securities Act of 1933, as amended. Bancorp has guaranteed, on a subordinated basis, distributions and other payments due on trust preferred securities totaling $8.0 million issued by the Trusts which have identical maturity, repricing and payment terms as the subordinated debentures.

The following is a summary of the contractual terms of the subordinated debentures due to the Trusts as of December 31, 2015:

Note 9: Stockholders' Equity and Stock Plans

Warrant

Under the United States Department of the Treasury Capital Purchase Program (the “TCPP”), Bancorp issued to the U.S. Treasury a warrant to purchase 154,242 shares of common stock at a per share exercise price of $27.23. The warrant was immediately exercisable and had an expiration date of December 5, 2018. The warrant was subsequently auctioned to two institutional investors in November 2011 and was exercised in September 2015. The warrant represented the right to purchase 157,711 shares of common stock at $26.63 per share. The cashless exercise resulted in the issuance of 70,591 shares of common stock in September 2015.

Share-Based Awards

On May 11, 2010, our shareholders approved the 2010 Director Stock Plan to pay director fees in shares of Bancorp common stock up to 150,000 shares. In 2015, 2014 and 2013, our directors were awarded a total of 5,295, 5,306 and 5,619 common shares, respectively, from the 2010 Director Stock Plan in addition to their cash compensation. As of December 31, 2015, 118,965 shares were available for future grants under this plan.

On May 8, 2007, the 2007 Equity Plan was approved by the Bank shareholders. The 2007 Equity Plan was subsequently adopted by Bancorp as part of the holding company formation. All new share-based awards from the approval date forward are granted through the 2007 Equity Plan.

The 2007 Equity Plan provides financial incentives for selected employees, advisors and non-employee directors. Terms of the plan provide for the issuance of up to 500,000 shares of common stock for these employees, advisors and non-employee directors. As of December 31, 2015, there were 205,297 shares available for future grants under the 2007 Equity Plan. The Compensation Committee of the Board of Directors has the discretion to determine which employees, advisors and non-employee directors will receive an award, the timing of awards, the vesting schedule for each award, the type of award to be granted, the number of shares of Bancorp stock to be subject to each option and restricted stock award, and any other terms and conditions. Restricted or unrestricted whole-share awards are limited to 250,000 of the total shares available under the 2007 Equity Plan.

Effective July 1, 2007, we adopted an Employee Stock Purchase Plan whereby our employees may purchase Bancorp common shares through payroll deductions of between one percent and fifteen percent of pay in each pay period. Shares are purchased quarterly at a five percent discount from the closing market price on the last day of the quarter. The plan calls for 200,000 common shares to be set aside for employee purchases, and there were 193,586 shares available for future grants under the plan as of December 31, 2015.

The inactive 1999 Stock Option Plan covered certain full-time employees and directors who had substantial responsibility for the successful operation of the Bank. Stock options granted pursuant to the 1999 Stock Option Plan were subsequently adopted by Bancorp as part of the holding company formation. Stock options under that plan now relate to shares of common stock of Bancorp. Upon approval of the 2007 Equity Plan, no new awards have been granted under the 1999 Stock Option Plan.

Options are issued at an exercise price equal to the fair value of the stock at the date of grant. Options to officers and employees granted prior to January 1, 2006 vested 20% immediately and 20% on each anniversary of the grant date for four years. Options and restricted stock awarded during 2006 through 2014 vest 20% on each anniversary of the grant date for five years. Beginning in 2015, options and restricted stock awards generally vest by approximately 33% on each anniversary of the grant date for three years. All officer and employee options expire ten years from the grant date. Options granted to non-employee directors vest 20% immediately and 20% on each anniversary of the grant date for four years. Director options expire seven years from the grant date.

Beginning in 2015, performance-based stock awards were 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

Page-82

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.

A summary of activity for stock options for the years ended December 31, 2015, 2014 and 2013 is presented below. The intrinsic value of options outstanding and exercisable is calculated as the number of in-the-money options times the difference between the market price of our stock as of each year end presented and the exercise prices of the in-the-money options.

As of December 31, 2015, there was $1.5 million of total unrecognized compensation expense related to non-vested stock options and restricted stock awards. This cost is expected to be recognized over a weighted-average period of approximately 2.3 years. The total grant-date fair value of option shares vested during the years ended December 31, 2015, 2014 and 2013 was $202 thousand, $182 thousand and $187 thousand, respectively. The total grant-date fair value of restricted stock awards vested during 2015, 2014 and 2013 was $262 thousand, $227 thousand and $218 thousand, respectively.

A summary of the options outstanding and exercisable by price range as of December 31, 2015 is presented in the following table:

The fair value of stock options on the grant date is recorded as a stock-based compensation expense in the consolidated statements of comprehensive income over the requisite service period with a corresponding increase in common stock. Stock-based compensation also includes compensation expense related to the issuance of restricted stock awards pursuant to the 2007 Equity Plan. The grant-date fair value of the restricted stock awards, which equals intrinsic value

Page-84

on that date, is being recorded as compensation expense over the requisite service period with a corresponding increase in common stock as the shares vest. Total compensation cost for these share-based payment arrangements was $636 thousand, $446 thousand and $403 thousand during 2015, 2014 and 2013, respectively, and the total recognized tax benefits related thereto were $194 thousand, $128 thousand and $109 thousand, respectively. In addition, we record excess tax benefits, if any, on the exercise of non-qualified stock options, the disqualifying disposition of incentive stock options and vesting of restricted stock awards as an addition to common stock with a corresponding decrease in current taxes payable. The tax benefit realized from disqualifying dispositions of incentive stock options recognized in the consolidated statements of comprehensive income during 2015, 2014 and 2013 was $49 thousand, $76 thousand and $94 thousand, respectively.

We determine the fair value of stock options at the grant date using the Black-Scholes pricing model that takes into account the stock price at the grant date, the exercise price, the expected life of the option, the volatility of the underlying stock, the expected dividend yield and the risk-free interest rate over the expected life of the option. The expected term of options granted is derived from historical data on employee exercise and post-vesting employment termination behavior. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. Expected volatility is based on the historical volatility of the common stock over the most recent period that is generally commensurate with the expected life of the options. The weighted-average assumptions used in the pricing model are noted in the table below.



	Years ended December 31,
	2015		2014		2013
Risk-free interest rate	1.67	%	2.04	%	1.60	%
Expected dividend yield on common stock	1.75	%	1.70	%	1.80	%
Expected life in years	6.0		6.0		6.8
Expected price volatility	28.06	%	30.32	%	30.01	%

The fair value of the option is expensed on a straight-line basis over the vesting period. Forfeitures are estimated based on historical forfeiture experience and expense is recognized only for those shares expected to vest.

The Black-Scholes option valuation model requires the input of highly subjective assumptions, including the expected life of the stock-based award and stock price volatility. The assumptions listed above represent Management's best estimates based on historical information, but these estimates involve inherent uncertainties and the application of Management's judgment. As a result, if other assumptions had been used, the recorded share-based compensation expense could have been materially different from that reflected in these financial statements. If the actual forfeiture rate is materially different from the estimate, the share-based compensation expense could also be materially different.

Dividends

Presented below is a summary of cash dividends paid to common shareholders, recorded as a reduction of retained earnings.



	Years ended December 31,
(in thousands except per share data)	2015		2014		2013
Cash dividends to common stockholders	$	5,390	$	4,733	$	3,970
Cash dividends per common share	$	0.90	$	0.80	$	0.73

The holders of the unvested restricted common stock awards are entitled to dividends on the same per-share ratio as the holders of common stock. Dividends paid on the portion of share-based awards not expected to vest are also included in stock-based compensation expense. Tax benefits on dividends paid on the portion of share-based awards expected to vest are recorded as an increase to common stock with a corresponding decrease in current taxes payable.

Under the California Corporations Code effective January 1, 2012, payment of dividends by Bancorp is restricted to the amount of retained earnings immediately prior to the distribution or the amount of assets that exceeds the total liabilities immediately after the distribution. As of December 31, 2015, Bancorp's retained earnings and the amount of assets that exceeds the total liabilities were $129.6 million and $214.5 million, respectively.

Page-85

Under the California Financial Code, payment of dividends by the Bank to Bancorp is restricted to the lesser of retained earnings or the amount of undistributed net profits of the Bank from the three most recent fiscal years. Under this restriction, approximately $20.5 million of the Bank's retained earnings balance was available for payment of dividends to Bancorp as of December 31, 2015. Bancorp held $3.8 million in cash at December 31, 2015. This cash, combined with the $20.5 million dividends available to be distributed from the Bank, is expected to be adequate to cover Bancorp's estimated operational needs and cash dividends to shareholders for 2016.

Preferred Stock and Shareholder Rights Plan

On July 2, 2007, Bancorp executed a shareholder rights agreement (“Rights Agreement”) designed to discourage takeovers that involve abusive tactics or do not provide fair value to shareholders. As of December 31, 2015, Bancorp was also authorized to issue five million shares of preferred stock with no par value under the Rights Agreement. In the event of a proposed merger, tender offer or other attempt to gain control of Bancorp that the Board of Directors does not approve, it might be possible for the Board of Directors to authorize the issuance of shares of common or preferred stock that would impede the completion of such a transaction. An effect of the possible issuance of common or preferred stock, therefore, may be to deter a future takeover attempt. The Board of Directors has no present plans or understandings for the issuance of any common or preferred stock in connection with the Rights Agreement.

Note 10: 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 in 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.

The following table summarizes our assets and liabilities that were required to be recorded at fair value on a recurring basis.

Securities available-for-sale are recorded at fair value on a recurring basis. When available, quoted market prices (Level 1) are used to determine the fair value of securities available-for-sale. 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

Page-87

rates, benchmark yield curves, prepayment speeds, probability of default, loss severity and credit spreads (Level 2). Level 2 securities include obligations of state and political subdivisions, U.S. agencies or government sponsored agencies' debt securities, mortgage-backed securities, government agency-issued and privately-issued collateralized mortgage obligations. As of December 31, 2015 and 2014, there are no securities that are considered Level 1 securities. As of December 31, 2015, we have one available-for-sale security that is considered Level 3 security. The security is a U.S. government agency obligation collateralized by a small pool of business equipment loans guaranteed by the Small Business Administration program. This security is not actively traded and is owned by a few investors. The significant unobservable data reflected in the fair value measurement include dealer quotes, projected prepayment speeds/average lives and credit information, among other things. It was transferred to Level 3 during the second quarter of 2014. During 2015, the decrease in unrealized gain was $7 thousand.

Securities held-to-maturity may be written down to fair value (determined using the same techniques discussed above for securities available-for-sale) as a result of an other-than-temporary impairment, if any.

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 quality in determining the fair value of derivatives. Level 2 inputs for the valuations are limited to observable market prices for London Interbank Offered Rate (“LIBOR”) and Overnight Index Swap ("OIS") rates (for the very short term), quoted prices for LIBOR futures contracts, observable market prices for LIBOR and OIS swap rates, and one-month and three-month LIBOR basis spreads at commonly quoted intervals. Mid-market pricing of the inputs is used as a practical expedient in the fair value measurements. We project spot rates at reset days specified by each swap contract to determine future cash flows, then discount to present value using either LIBOR or OIS curves depending on the collateral posted as of the measurement date. When the value of any collateral placed with counterparties is less than the interest rate derivative liability, a credit valuation adjustment ("CVA") is applied to reflect the credit risk we pose to counterparties. We have used the spread between the Standard & Poor's BBB rated U.S. Bank Composite rate and LIBOR for the closest maturity term corresponding to the duration of the swaps to derive the CVA. A similar credit risk adjustment, correlated to the credit standing of the counterparty, is made when collateral posted by the counterparty does not fully cover their liability to Bank of Marin. For further discussion on our methodology in valuing our derivative financial instruments, refer to Note 15.

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 impaired loans and other real estate owned ("OREO").

The following table presents the carrying value of financial instruments that were measured at fair value on a non-recurring basis and were still held in the consolidated statements of condition at each respective period end, by level within the fair value hierarchy as of December 31, 2015 and 2014.



(in thousands) Description of Financial Instruments	Carrying Value¹		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3) ¹
December 31, 2015
Other real estate	$	421	$	—	$	—	$	421

December 31, 2014

Other real estate	$	461	$	—	$	—	$	461

¹Represents collateral-dependent loan principal balances that had been generally written down to the values of the underlying collateral, net of specific valuation allowances. At December 31, 2014, the $77 thousand carrying value of a consumer loan was net of a $26 thousand specific valuation allowance. The carrying value of loans fully charged-off, which includes unsecured lines of credit, overdrafts and all other loans, is zero.

When a loan is identified as impaired, it is reported at the lower of cost or fair value, measured based on the loan's observable market price (Level 1) or the current net realizable value of the underlying collateral securing the loan, if

Page-88

the loan is collateral dependent (Level 3). Net realizable value of the underlying collateral is the fair value of the collateral less estimated selling costs and any prior liens. Appraisals, recent comparable sales, offers and listing prices are factored in when valuing the collateral. We review and verify the qualifications and licenses of the certified general appraisers used for appraising commercial properties or certified residential appraisers for residential properties. Real estate appraisals may utilize a combination of approaches including replacement cost, sales comparison and the income approach. Comparable sales and income data are analyzed by the appraisers and adjusted to reflect differences between them and the subject property such as type, leasing status and physical condition. When appraisals are received, Management reviews the assumptions and methodology utilized in the appraisal as well as the overall resulting value in conjunction with independent data sources such as recent market data and industry-wide statistics. We generally use a 6% discount for selling costs which is applied to all properties, regardless of size. Appraised values may be adjusted to reflect changes in market conditions that have occurred subsequent to the appraisal date, or for revised estimates regarding the timing or cost of the property sale. These adjustments are based on qualitative judgments made by Management on a case-by-case basis and are generally unobservable valuation inputs as they are specific to each underlying collateral. There have been no significant changes in the valuation techniques during the period ended December 31, 2015.

OREO represents collateral acquired through foreclosure and is initially recorded at fair value as established by a current appraisal, adjusted for disposition costs. Subsequently, OREO is measured at lower of cost or fair value. OREO values are reviewed on an ongoing basis and any subsequent decline in fair value is recorded as a foreclosed asset expense in the current period. The value of OREO is determined based on independent appraisals, similar to the process used for impaired loans, discussed above, and is classified as Level 3. There was a $40 thousand decline in the estimated fair value of the OREO during the year ended December 31, 2015. The OREO was acquired from Bank of Alameda as part of the NorCal Acquisition.

Disclosures about Fair Value of Financial Instruments

The table below is a summary of fair value estimates for financial instruments as of December 31, 2015 and 2014, 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. We have excluded non-financial assets and non-financial liabilities defined by the Codification (ASC 820-10-15-1A), such as Bank premises and equipment, deferred taxes and other liabilities. In addition, we have not disclosed the fair value of financial instruments specifically excluded from disclosure requirements of the Financial Instruments Topic of the Codification (ASC 825-10-50-8), such as Bank-owned life insurance policies.

Page-89

Following is a description of methods and assumptions used to estimate the fair value of each class of financial instrument not recorded at fair value but required for disclosure purposes:

Cash and Cash Equivalents - The carrying amounts of cash and cash equivalents approximate their fair value because of the short-term nature of these instruments.

Held-to-maturity Securities - Held-to-maturity securities, which generally consist of obligations of state and political subdivisions and corporate bonds, are recorded at their amortized cost. Their fair value for disclosure purposes is determined using methodologies similar to those described above for available-for-sale securities using Level 2 inputs. If Level 2 inputs are not available, we may utilize pricing models that incorporate unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities (Level 3). As of December 31, 2015 and 2014, we did not hold any securities whose fair value was measured using significant unobservable inputs.

Loans - The fair value of loans with variable interest rates approximates their current carrying value, because their rates are regularly adjusted to current market rates. The fair value of fixed rate loans or variable loans at negotiated interest rate floors or ceilings with remaining maturities in excess of one year is estimated by discounting the future cash flows using current market rates at which similar loans would be made to borrowers with similar credit worthiness and similar remaining maturities. The allowance for loan losses (“ALLL”) is considered to be a reasonable estimate of the portion of loan discount attributable to credit risks.

Interest Receivable and Payable - The interest receivable and payable balances approximate their fair value due to the short-term nature of their settlement dates.

Deposits - The fair value of deposits without stated maturity, such as transaction accounts, savings accounts and money market accounts, is the amount payable on demand at the reporting date. The fair value of time deposits is estimated by discounting the future cash flows using current rates offered for deposits of similar remaining maturities.

Federal Home Loan Bank Borrowing - The fair value is estimated by discounting the future cash flows using current rates offered by the Federal Home Loan Bank of San Francisco ("FHLB") for similar credit advances corresponding to the remaining duration of our fixed-rate borrowing.

Subordinated Debentures - As part of the NorCal Acquisition, we assumed two subordinated debentures. See Notes 2 and 8 for further information. The fair values of the subordinated debentures were estimated by discounting the future cash flows (interest payment at a rate of forward three-month LIBOR plus 3.05% and 1.40%, respectively) to their present values using current market rates at which similar bonds would be issued with similar credit ratings as ours and similar remaining maturities. Each payment was discounted at a spot rate of the corresponding term, determined based on the yields and terms of comparable trust preferred securities, plus a liquidity premium. In July 2010, the Dodd-Frank Act was signed into law and limits the ability of certain bank holding companies to treat trust preferred security debt issuances as Tier 1 capital. This law effectively closed the trust-preferred securities markets for new issuance and led to the absence of observable or comparable transactions in the market place. Due to the unobservable inputs of trust preferred securities, we consider the fair value to be a Level 3 measurement.

Commitments - The value of unrecognized 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 December 31, 2015 and 2014, respectively.

Note 11: Benefit Plans

In 2003, we established a Deferred Compensation Plan that allows certain key management personnel designated by the Board of Directors of the Bank to defer up to 80% of their salary and 100% of their annual bonus. The plan was amended in 2007 in order to comply with the most recent Internal Revenue Code Section 409A changes. Under the amended plan, amounts deferred earn interest that is equal to the prime rate as published in the Wall Street Journal, on the first business day of the year, which remained unchanged at 3.25% on January 1, 2015, 2014 and 2013. In January 2016, the crediting rate increased to 3.50%. Our deferred compensation obligation totaled $3.0 million and $2.9 million at December 31, 2015 and 2014, respectively, and is included in interest payable and other liabilities.

Page-90

Our 401(k) Defined Contribution Plan (the “401(k) Plan”) commenced in May 1990 and is available to all regular employees at least eighteen years of age who complete ninety days of service, and enter the plan during one of the four open enrollment dates (January 1, April 1, July 1, and October 1) of each year. Under the 401(k) Plan, employees can defer between 1% and 50% of their eligible compensation, up to the maximum amount allowed by the Internal Revenue Code. Contributions to the 401 (k) Plan for the employer match are vested at a rate of 20% per year over a five year period. The Bank matched 50% of each participant's contribution prior to 2013 at which time the Bank increased the match to 60%, with a maximum of $4 thousand annually. Employer contributions totaled $555 thousand, $548 thousand and $473 thousand for the years ended December 31, 2015, 2014 and 2013, respectively.

In 1999, the 401(k) Plan was amended to include an employee stock ownership component and was renamed the Bank of Marin Employee Stock Ownership and Savings Plan (the “Plan”). Under the terms of the Plan, as amended, the Board of Directors determines a specific portion of the Bank's profits to be contributed to the employee stock ownership each year either in common stock or in cash for the purchase of Bancorp stock to be allocated to all eligible employees based on a percentage of their salaries, regardless of whether an employee is participating in the 401(k) plan or not. In January 2010, the Bank of Marin Employee Stock Ownership and Savings Plan was split into two plans: Bank of Marin 401(k) Plan and Bank of Marin Employee Stock Ownership Plan ("ESOP"). The same eligibility criteria apply under the ESOP, while employees' contributions are not permitted. For all participants, employer contributions vest over a five year period of service. After five years of service, all past and future employer contributions vest immediately.

The Bank contributed cash in the amount of $1.1 million for the year ended December 31, 2015, $1.2 million in 2014, and $886 thousand in 2013, to the ESOP, which purchased Bancorp stock from the open market or private parties. Cash dividends paid on Bancorp stock held by the ESOP are used to purchase additional shares in the open market. All shares of Bancorp stock held by the ESOP are included in the calculations of basic and diluted earnings per share. The employer contributions to the ESOP and the 401(k) Plan are included in salaries and benefits expense.

On January 1, 2011, we established a Salary Continuation Plan for a select group of Executive Management, who will receive twenty-five percent of their estimated salary at retirement as salary continuation benefit payments upon retirement. Each participant will need to participate in this plan for five years before vesting begins. After five years, the participant will vest ratably in the benefit over the remaining period until age 65. This Plan is unfunded and nonqualified for tax purposes and for purposes of Title I of the Employee Retirement Income Security Act of 1974. Our liability under the Salary Continuation Plan was $823 thousand and $644 thousand recorded in interest payable and other liabilities at December 31, 2015 and 2014, respectively.

As of December 31, 2015, we had Federal and California net operating loss carryforwards ("NOLs") from the NorCal Acquisition of approximately $7.6 million and $21.3 million, respectively. If not fully utilized, the federal NOLs will begin to expire in 2029, and the California NOLs will begin to expire in 2028. The acquisition resulted in limitations on the annual utilization of these NOLs under section 382 of the Internal Revenue Code. Although we expect to fully utilize all of the federal NOLs prior to their expiration, $819 thousand of California NOLs are expected to expire unutilized in 2031. As a result, we wrote down $58 thousand of deferred tax assets associated with these California NOLs as part of the purchase accounting adjustments in 2013. Based upon the level of historical taxable income and projections for future taxable income over the periods during which the deferred tax assets are expected to be deductible, Management believes it is more likely than not we will realize the benefit of the remaining deferred tax assets. Accordingly, no other valuation allowance has been established as of December 31, 2015 or 2014.

The effective tax rate for 2015, 2014 and 2013 differs from the current Federal statutory income tax rate as follows:



	2015		2014		2013
Federal statutory income tax rate	35.0	%	35.0	%	35.0	%
Increase (decrease) due to:
California franchise tax, net of federal tax benefit	6.8	%	6.8	%	6.5	%

Bancorp and the Bank have entered into a tax allocation agreement which provides that income taxes shall be allocated between the parties on a separate entity basis. The intent of this agreement is that each member of the consolidated group will incur no greater tax liability than it would have incurred on a stand-alone basis.

Note 13: Commitments and Contingencies

We rent certain premises and equipment under long-term, non-cancelable operating leases expiring at various dates through the year 2028. Most of the leases contain certain renewal options and escalation clauses. At December 31, 2015, the approximate minimum future commitments payable under non-cancelable contracts for leased premises are as follows:



(in thousands)	2016		2017		2018		2019		2020		Thereafter		Total
Operating leases¹	$	3,763	$	3,755	$	3,784	$	3,526	$	3,018	$	3,659	$	21,505

¹ Minimum payments have not been reduced by minimum sublease rentals of $248 thousand due in the future under non-cancelable subleases.

Rent expense included in occupancy expense totaled $4.2 million in 2015 and 2014, and $3.3 million in 2013.

We are responsible for our proportionate share of certain litigation indemnifications provided to Visa U.S.A. ("Visa") by its member banks in connection with lawsuits related to anti-trust charges and interchange fees ("Covered Litigation"). Visa Inc. maintains an escrow account from which settlements of, or judgments in, the Covered Litigation are paid. While the accrual related to the Covered Litigation could be higher or lower than the litigation escrow account balance, Visa did not record an additional accrual for the Covered Litigation during 2015. At December 31, 2015, the balance of the escrow account was $1.0 billion. According to the latest SEC Form 10-Q filed by VISA, Inc. on January 28, 2016, Visa has reached settlement agreements with a number of opt-out merchants. They represent approximately 49% of the Visa-branded payment card sales volume of merchants who opted out of interchange multidistrict litigation class settlement agreement, under which an estimated $4.0 billion is due to the class plaintiffs. The conversion rate of Visa Class B common stock held by us to Class A common stock (as discussed in Note 3) may decrease if Visa makes more Covered Litigation settlement payments in the future, and the full effect on member banks is still uncertain. However, we are not aware of significant future cash settlement payments required by us on the Covered Litigation.

As permitted or required under California law and to the maximum extent allowable under that law, we have certain obligations to indemnify our current and former officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. These indemnification obligations are valid as long as the director or officer acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The maximum potential amount of future payments we could be required to make under these indemnification obligations is unlimited; however, we have a director and officer insurance policy that mitigates our exposure and enables us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification obligations is minimal.

Page-93

Note 14: Concentrations of Credit Risk

Concentration of credit risk is the risk associated with a lack of diversification, such as having substantial investments in a few individual issuers, thereby exposing us to greater risks resulting from adverse economic, political, regulatory, geographic, industrial or credit developments. Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investment securities and loans.

Our cash in correspondent bank accounts, at times, may exceed FDIC insured limits. We place cash and cash equivalents with high quality financial institutions, periodically monitor their credit worthiness and limit the amount of credit exposure with any one institution. Concentrations of credit risk with respect to investment securities are limited to the U.S. Government, its agencies and Government Sponsored Enterprises ("GSEs"). Our exposure, which primarily results from positions in securities issued by the U.S. Government, its agencies, and GSEs was $362.6 million, or 74% of our total investment portfolio at December 31, 2015 and $185.4 million, or 58% at December 31, 2014.

We also manage our credit exposure related to our loan portfolio to avoid the risk of undue concentration of credits in a particular industry by reducing significant exposure to highly leveraged transactions or to any individual customer or counterparty, and by obtaining collateral as appropriate. No individual borrower accounts for more than 5% of loans held in the portfolio. The largest loan concentration group by industry of the borrowers is real estate, which accounts for 80% of our loan portfolio at both December 31, 2015 and 2014.

Note 15: Derivative Financial Instruments and Hedging Activities

We have entered into interest rate swap agreements, primarily as an asset/liability management strategy, in order to mitigate the changes in the fair value of specified long-term fixed-rate loans (or firm commitments to enter into long-term fixed-rate loans) caused by changes in interest rates. These hedges allow us to offer long-term fixed rate loans to customers without assuming the interest rate risk of a long-term asset. Converting our fixed-rate interest payments to floating-rate interest payments, generally benchmarked to the one-month U.S. dollar LIBOR index, protects us against changes in the fair value of our loans associated with fluctuating interest rates.

The fixed-rate payment features of the interest rate swap agreements are generally structured at inception to mirror substantially all of the provisions of the hedged loan agreements. These interest rate swaps, designated and qualified as fair value hedges, are carried on the consolidated statements of condition at their fair value in other assets (when the fair value is positive) or in other liabilities (when the fair value is negative). The unrealized gain or loss in fair value of the hedged fixed-rate loan due to LIBOR interest rate movements is recorded as an adjustment to the hedged loan.

From time to time, we make firm commitments to enter into long-term fixed-rate loans with borrowers backed by yield maintenance agreements and simultaneously enter into forward interest rate swap agreements with correspondent banks to mitigate the change in fair value of the yield maintenance agreement. Prior to loan funding, yield maintenance agreements with net settlement features that meet the definition of a derivative are considered as non-designated hedges and are carried on the consolidated statements of condition at their fair value in other assets (when the fair value is positive) or in other liabilities (when the fair value is negative). The offsetting changes in the fair value of the forward swap and the yield maintenance agreement are recorded in interest income. When the fixed-rate loans are originated, the forward swaps are designated to offset the change in fair value in the loans. Subsequent to the point of the swap designations, the related yield maintenance agreements are no longer considered derivatives. Their fair value at the designation date was recorded in other assets and is amortized using the effective yield method over the life of the respective designated loans.

The net effect of the change in fair value of interest rate swaps, the amortization of the yield maintenance agreement and the change in the fair value of the hedged loans result in an insignificant amount of hedge ineffectiveness recognized in interest income.

Our credit exposure, if any, on interest rate swaps is limited to the favorable 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.

Page-94

As of December 31, 2015, we had seven interest rate swap agreements, which are scheduled to mature in June 2020, August 2020, June 2031, October 2031, July 2032, August 2037 and October 2037. All of our derivatives are accounted for as fair value hedges. Our interest rate swaps are settled monthly with counterparties. Accrued interest on the swaps totaled $28 thousand and $41 thousand as of December 31, 2015 and December 31, 2014, respectively. Information on our derivatives follows:

² Includes hedge ineffectiveness loss of $80 thousand, gain of $194 thousand and loss of $362 thousand for the years December 31, 2015, 2014 and 2013, respectively. Changes in value of swaps were included in the assessment of hedge effectiveness. Hedge ineffectiveness is the measure of the extent to which the change in the fair value of the hedging instruments does not offset the change in the fair value of the hedged item.

Our derivative transactions with counterparties are under International Swaps and Derivative Association (“ISDA”) master agreements that include “right of set-off” provisions. “Right of set-off” provisions are legally enforceable rights to offset recognized amounts and there may be an intention to settle such amounts on a net basis. We do not offset such financial instruments for financial reporting purposes.

Note 16: Regulatory Matters

We are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a 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.

Quantitative measures established by regulation to ensure capital adequacy require Bancorp and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to quarterly average assets.

Capital ratios are reviewed by Management on a regular basis to ensure that capital exceeds the prescribed regulatory minimums and is adequate to meet our anticipated future needs. 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 for capital adequacy purposes.

In July 2013, the Board of Governors of the Federal Reserve, the FDIC and the Office of the Comptroller of the Currency, finalized regulatory capital rules known as “Basel III.” The rules became effective beginning January 2015, and will be phased-in and become fully implemented by January 2019. The guidelines, among other things, changed the minimum capital requirements of bank holding companies, by increasing the Tier 1 capital to risk-weighted assets ratio to 6%, and introducing a new requirement to maintain a minimum ratio of common equity Tier 1 capital to risk-weighted assets of 4.5%. By 2019, when fully phased in, the rules will require further increases to certain minimum capital requirements and a capital conservation buffer of an additional 2.5% of risk-weighted assets. Basel III permits certain banks such as us to exclude accumulated other comprehensive income or loss from regulatory capital through a one-time election in the first quarter of 2015. As it was consistent with our existing treatment, there were no changes to our capital ratios as a result of making this election. The changes that affected us most significantly include:


•	shifting off-balance sheet items with an original maturity of one year or less from 0% to 20% risk weight,


•	moving past due loan balances from 100% to 150% risk weight,


•	deducting deferred tax assets associated with NOLs and tax credits from common equity Tier 1 capital, and


•	subjecting deferred tax assets related to temporary timing differences that exceed certain thresholds to 250% risk-weighting, beginning in 2018.

We have modeled our ratios under fully phased-in Basel III rules and, based on present facts, we do not expect that we will be required to raise additional capital as a result of the fully phased-in rules.

To be categorized as well capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 leverage, and common equity Tier 1 ratios as set forth in the second table below. The most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action as of December 31, 2015. 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 under the minimum requirements for capital adequacy in accordance with Basel III rules for prompt corrective action pursuant to Section 38 of the Federal Deposit Insurance Act on a fully phased-in basis.

The Bancorp’s and Bank's capital adequacy ratios as of December 31, 2015 and 2014 are presented in the following tables. Bancorp's Tier 1 capital includes the subordinated debentures, which are not included at the Bank level. We continued to deploy capital in 2015 accumulated from net income into lending and investing.

Note 17: 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. Since some of the commitments are expected to expire without being fully drawn upon, the total commitment amount does not necessarily represent future cash requirements.

We are exposed to credit loss equal to the contract amount of the commitment in the event of nonperformance by the borrower. We use the same credit policies in making commitments as we do for on-balance-sheet instruments and we evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by us, is based on Management's credit evaluation of the borrower. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and real property.

The contractual amount of loan commitments and standby letters of credit not reflected on the consolidated statements of condition was $376.6 million and $349.3 million at December 31, 2015 and 2014, respectively. This amount included $191.3 million and $173.3 million under commercial lines of credit (these commitments are contingent upon customers maintaining specific credit standards), $130.4 million and $115.6 million under revolving home equity lines, $39.4 million and $46.7 million under undisbursed construction loans, $11.1 million and $11.6 million under personal and other lines of credit, and a remaining $4.4 million and $2.1 million under standby letters of credit at December 31, 2015 and 2014, respectively. We record an allowance for losses on these off-balance sheet commitments based on an estimate of probabilities of these commitments being drawn upon according to our historical utilization experience on different

Page-98

types of commitments and expected loss severity. In 2015 we refined our methodology used in the calculation of the loss reserve on off-balance sheet commitments to more appropriately reflect the inherent credit risks, which totaled $749 thousand and $1.0 million as of December 31, 2015 and 2014, respectively. Approximately 42% of the commitments expire in 2016, approximately 41% expire between 2017 and 2023 and approximately 17% expire thereafter.

ITEM 9.	CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

(A) 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, or persons performing similar functions, 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 1934 Act) as of December 31, 2015. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2015.

The term disclosure controls and procedures means controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the 1934 Act (15 U.S.C. 78a et seq.) is recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the 1934 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.

(B) Management's Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining effective internal control over financial reporting (as defined in Rules 13a-15(f) promulgated under the 1934 Act). The internal control process has been designed under our supervision to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's financial statements for external reporting purposes in accordance with accounting principles generally accepted in the United States of America.

Management conducted an assessment of the effectiveness of internal control over financial reporting as of December 31, 2015, utilizing the framework established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2015.

There are inherent limitations to the effectiveness of any system of internal control over financial reporting. These limitations include the possibility of human error, the circumvention or overriding of the system and reasonable resource constraints. Because of its inherent limitations, our internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management's report on internal control over financial reporting is set forth in Item 8 and is incorporated herein by reference.

The Company's independent registered public accounting firm, Moss Adams, LLP, has audited the effectiveness of internal control over financial reporting as of December 31, 2015 as stated in their attestation report, which is included in item 8 and incorporated herein by reference.

(D) Changes in Internal Control Over Financial Reporting

Page-102

During the quarter ended December 31, 2015, there was no significant change in our internal control over financial reporting identified in connection with the evaluation mentioned in (B) above, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
