Proxies are solicited to give all Shareholders of Record (“registered holder”) an opportunity to vote on matters to be presented at the Annual Meeting. In the following pages of this Proxy Statement, you will find information on matters to be voted at the Annual Meeting. Voting Information Internet Availability of Proxy Materials. We are providing proxy materials to our shareholders primarily via the internet, instead of mailing printed copies of those materials to each shareholder. By doing so, we save costs and reduce the environmental impact of our Annual Meeting. On or about March 12, 2018, we mailed a Notice of Internet Availability of Proxy Materials (“Notice”) to certain of our shareholders. The Notice contains instructions about how to access our proxy materials and vote online or vote by telephone. If you would like to receive a paper copy of our proxy materials, please follow the instructions included in the Notice. If you previously chose to receive our proxy materials electronically, you will continue to receive access to these materials via email unless you elect otherwise. Proof of Ownership May Be Required for Attending Annual Meeting in Person. You are entitled to attend the Annual Meeting only if you are a shareholder as of the close of business on February 26, 2018, the record date, or hold a valid proxy for the meeting. In order to be admitted to the Annual Meeting, the Company reserves the right to request proof of ownership of Westamerica Bancorporation common stock on the record date. This can be:  A brokerage statement or letter from a bank or broker indicating ownership on February 26, 2018;  The Notice of Internet Availability of Proxy Materials;  A printout of proxy distribution email (if you received your materials electronically);  A Proxy Card;  A voting instruction form; or  A legal proxy provided by your broker, bank or nominee. Any holder of a proxy from a shareholder must present the Proxy Card properly executed, and a copy of the proof of ownership. The Company reserves the right to ask shareholders and proxy holders to present a form of photo identification such as a driver’s license. Proxy Card. The Board has designated Arthur C. Latno, Jr., Ronald A. Nelson and Edward B. Sylvester to serve as Proxies for the Annual Meeting. As Proxies, they will vote the shares represented by proxies at the Annual Meeting. If you sign, date and return your Proxy Card but do not specify how to vote your shares, the Proxies will vote FOR the election of all of the Director nominees, FOR approval of the advisory vote on the compensation of our named executive officers, and FOR ratifying the selection of independent auditor. The Proxies will also have 1 1 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 discretionary authority to vote in accordance with their judgment on any other matter that may properly come before the Annual Meeting that we did not have notice of by January 26, 2018. Quorum and Shares Outstanding. A quorum, which is a majority of the total shares outstanding as of the record date, must be present to hold the Annual Meeting. A quorum is calculated based on the number of shares represented by shareholders attending in person or by proxy. On February 26, 2018, 26,574,333 shares of Westamerica Bancorporation common stock were outstanding. We also count broker non-votes, which we describe below, as shares present or represented at the Annual Meeting for the purpose of determining whether a quorum exists. Election of Director Nominees. Each share is entitled to one vote, except in the election of Directors where a shareholder may cumulate votes as to candidates nominated prior to voting, but only when a shareholder gives notice of intent to cumulate votes prior to the voting at the Annual Meeting. If any shareholder gives such notice, all shareholders may cumulate their votes for nominees. Under cumulative voting, each share carries as many votes as the number of Directors to be elected, and the shareholder may cast all of such votes for a single nominee or distribute them in any manner among as many nominees as desired. This Proxy Statement solicits the discretionary authority to cumulate votes and allocate them in the Proxy Holders’ discretion if any shareholder requests cumulative voting. In the election of Directors, the nine nominees receiving the highest number of votes will be elected. If your proxy is marked “Withhold” with regard to the election of any nominee, your shares will be counted toward a quorum and for other nominees but they will not be voted for the election of that nominee. If you attend the Annual Meeting and have already voted, you may vote in person in order to rescind your previous vote. Vote Required; Effect of Abstentions and Broker Non-Votes. The shares of a shareholder whose ballot on any or all proposals is marked as “abstain” will be included in the number of shares present at the Annual Meeting to determine whether a quorum is present. If you are the beneficial holder of shares held by a broker or other custodian, you may instruct your broker how to vote your shares through the voting instruction form included with this Proxy Statement. If you wish to vote the shares you own beneficially at the meeting, you must first request and obtain a legal proxy from your broker or other custodian. If you choose not to provide instructions or a legal proxy, your shares are referred to as “uninstructed shares.” Whether your broker or custodian has the discretion to vote these shares on your behalf depends on the ballot item. The following table summarizes the votes required for passage of each proposal and the effect of abstentions and uninstructed shares held by brokers. Brokers and custodians cannot vote uninstructed shares on your behalf in director elections or advisory votes on executive compensation. For your vote to be counted, you must submit your voting instruction form to your broker or custodian. Election of directors Nine nominees receiving the most votes Advisory vote on executive compensation "Say on Pay" Majority of shares voted Not voted Not voted Not voted Not voted Ratification of independent auditor Majority of shares voted Not voted Broker discretionary vote 1 2 3 FOR FOR FOR Votes in favor of Proposals 2 and 3 must also constitute a majority of the required quorum for the meeting. If votes in favor are less than a majority of the required quorum, abstentions and non-votes will have the effect of a vote against the proposal. 22 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y Other Matters. Approval of any other matter considered at the Annual Meeting will require the affirmative vote of a majority of the shares present or represented by proxy and voting at the Annual Meeting and a majority of the required quorum. How You Can Vote. Your vote is very important and we hope that you will attend the Annual Meeting. However, whether or not you plan to attend the Annual Meeting, please vote by proxy. Registered Holders. If your shares are registered directly in your name with the Company’s transfer agent, Computershare Investor Services, LLC, you are considered a registered holder of those shares. Please vote by proxy in accordance with the instructions on your Proxy Card, or the instruction you received by email. A registered holder can vote in one of the following four ways:  Via the Internet. Go to the website noted on your Proxy Card in order to vote via the internet. Internet voting is available 24 hours a day. We encourage you to vote via the internet, as it is the most cost- effective way to vote. When voting via the internet, you do not need to return your Proxy Card.  By Telephone. Call the toll-free telephone number indicated on your Proxy Card and follow the voice prompt instructions to vote by telephone. Telephone voting is available 24 hours a day. When voting by telephone, you do not need to return your Proxy Card.  By Mail. Mark your Proxy Card, sign and date it, and return it in the enclosed postage-paid envelope. If you elected to electronically access the Proxy Statement and Annual Report, you will not be receiving a Proxy Card and must vote via the internet or by telephone.  In person. You may vote your shares at the Annual Meeting if you attend in person, even if you previously submitted a Proxy Card or voted via internet or telephone. Whether or not you plan to attend the Annual Meeting, however, we strongly encourage you to vote your shares by proxy before the meeting. We have been advised by counsel that these telephone and internet voting procedures comply with California law. Beneficial Shareholders. If your shares are held in a brokerage account in the name of your bank, broker, or other holder of record (“beneficial holder” or “street name”), you are not a registered holder, but rather are considered a beneficial holder of those shares. Your bank, broker, or other holder of record will send you instructions on how to vote your shares. If you are a beneficial holder, you must obtain a legal proxy, executed in your favor, from the holder of record to be able to vote in person at the Annual Meeting. If you are a participant the Westamerica Bancorporation Tax Deferred in Voting Deadlines. Savings/Retirement Plan (ESOP) your vote must be received by 11:59 p.m. Central Time, on April 23, 2018. All other shareholders voting by telephone or internet must vote by 12:01 a.m. Central Time, on April 26, 2018 to ensure that their vote is counted. Revocation of Proxy. Registered Holders who vote by proxy, whether by telephone, internet or mail, may revoke that proxy at any time before it is voted at the Annual Meeting. You may do this by: (a) signing another Proxy Card with a later date and delivering it to us prior to the Annual Meeting or sending a notice of revocation to the Corporate Secretary of Westamerica at 1108 Fifth Avenue, San Rafael, CA 94901; (b) voting 3 3 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 at a later time by telephone or on the internet prior to 12:01 a.m. Central Time, on April 26, 2018 (prior to 11:59 p.m. Central Time, on April 23, 2018 for ESOP participants); or (c) attending the Annual Meeting in person and casting a ballot. If you are a beneficial holder, you may change your vote by submitting new voting instructions to your broker or other nominee. Additional Information Householding. As permitted by the Securities Exchange Act of 1934 (the “Exchange Act”) only one envelope containing two or more Notices of Internet Availability of Proxy Materials is being delivered to shareholders residing at the same address, unless such shareholders have notified their bank, broker, Computershare Investor Services, or other holder of record that they wish to receive separate mailings.

Robinson, Sylvester and Thorson with respect to the disposition of 9,200, 1,260 and 2,000 shares, respectively, and for two reports filed seventy-three days delinquent for Messrs. Hansen and Schneck with respect to the grant of nonqualified stock options of 19,400 and 5,900 shares, respectively, with one-third vesting on the first anniversary date of the grant date. PROPOSAL 1 – ELECTION OF DIRECTORS Board of Directors Nine Directors have been nominated for election at the Annual Meeting to hold office until the next Annual Meeting or until their successors are elected and qualified.

The Proxies will vote for any substitute nominated by the Board of Directors. The Proxies may use their discretion to cumulate votes for election of Directors and cast all of such votes for any one or more of the nominees, to the exclusion of the others, and in such order of preference as they may determine at their discretion. Nominees The nominees for election as Directors are named and certain information with respect to them is given below.

THE BOARD OF DIRECTORS RECOMMENDS ELECTION OF ALL NOMINEES Board of Directors and Committees Director Independence and Leadership Structure The Board of Directors has considered whether any relationships or transactions related to a Director were inconsistent with a Director’s independence. Based on this review, the Board has determined that E. Allen, L.E. 9 9 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 Bartolini, E.J. Bowler, A.C. Latno, Jr., P.D. Lynch, C.C. MacMillan, R.A. Nelson, and E.B. Sylvester are “independent” Directors as defined in NASDAQ rules. Our Board has carefully considered the critical issue of Board leadership. In the context of risk management, the leadership of each Board committee primarily responsible for risk management is vested in an independent committee chair. With regard to the leadership of the meetings of the full Board, our Board of Directors has carefully evaluated whether the positions of chairman and CEO should be separate or combined. Our Board believes that the most effective leadership structure for the Company at this time is to combine the responsibilities of the Chairman and CEO, a structure that has been successful since 1989. The combined positions avoid a duplication of efforts, enable decisive leadership, ensure a clear accountability for the performance of the Company, a more rapid implementation of decisions, and a consistent vision. Given the size of our employee base and our level of assets relative to larger, more complex banking structures, our Company is particularly well suited to combine the Chairman and CEO functions. Furthermore, our management team has an average tenure of 23 years and does not require the substantial oversight needed by a less experienced team, which has allowed our Chairman and CEO to lead the Company through eleven acquisitions since 1992. To ensure strong Board oversight eight of our nine Directors are, as noted above, independent as defined by NASDAQ. Only non-management directors sit on Board committees, with the exception of the Executive Committee, and every non-management director sits on one or more of these Committees. All non-management directors meet at least four times a year outside the presence of the Chairman and CEO. The Board completes an annual board evaluation that is discussed by the Nominating Committee and presented to the full Board. Although the Board believes that it is more effective to have one person serve as the Chairman and CEO at this time, it also recognizes the importance of strong independent leadership on the Board, accordingly, the Board has established a strong, independent Lead Director, Mr. Sylvester, who must serve at least one year and has the following clearly delineated and comprehensive duties:  Presides at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent Directors;  Serves as liaison between the Chairman and the independent Directors;  Approves information sent to the Board;  Approves meeting agendas for the Board;  Approves meeting schedules to assure that there is sufficient time for discussion of all agenda items;  Has the authority to call meetings of the independent Directors; and  If requested by major shareholders, ensures that he or she is available for consultation and direct communication. The Board does not believe that the fact an independent Lead Director does not preside over the normal Board meeting business sessions limits the ability of the Board to have open exchanges of views, or to address any issues the Board chooses, independently of the Chairman. The Board of Directors of the Company also serve as the Board of Directors of Westamerica Bank, and as such are well informed of Bank operations through regular reports and discussions on the operations of the Bank. The Directors’ longevity with the Company has exposed them to a wide range of business cycles, which plays a critical role in managing the risk profile and profitability of the Company through the current economic environment. Role of the Board of Directors in Risk Oversight The Board is also responsible for overseeing all aspects of management of the Company, including risk oversight, which is effected through all Board committees, but primarily through the Board’s Audit Committee. The Internal 1010 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y Audit Department reports directly to the Board’s Audit Committee. It presents its independently prepared company- wide annual risk assessment, its evaluation of Management’s prepared risk assessment and its audit plan incorporating the risk assessment, including the policies and procedures utilized to monitor and control such exposures, to the Board’s Audit Committee. The internal loan review function reports directly to the Board’s Audit Committee. It reports ongoing evaluations of loan portfolios and the risk rating of individual loans using guidelines established by bank regulatory authorities, to the Board’s Audit Committee. Meetings The Company expects all Board members to attend all meetings, including the Annual Meeting of Shareholders, except for reasons of health or special circumstances. The Board met on nine days during 2017. Every Director attended at least 75% of the aggregate of: (i) the Board meetings held during that period in which they served; and (ii) the total number of meetings of any Committee of the Board on which the Director served. Each individual who served on the Board of the Company on the date of the 2017 Annual Meeting of Shareholders attended the meeting, except for Ms. Allen.

Audit Committee The Board of Directors has determined that all members are independent, as that term is defined by applicable rules of NASDAQ for Audit Committee purposes. The Board has also designated Mr. Nelson as the “Audit Committee financial expert” as defined by the rules of the SEC and has determined that he is “financially sophisticated” under NASDAQ rules. In concluding that Mr. Nelson is the Audit Committee financial expert, the Board determined that he has:  an understanding of generally accepted accounting principles and financial statements;  the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves; 11 11 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2  experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the Company’s financial statements, or experience actively supervising one or more persons engaged in such activities;  an understanding of internal control over financial reporting; and  an understanding of Audit Committee functions. Designation of a person as an Audit Committee financial expert does not result in the person being deemed an expert for any purpose, including under Section 11 of the Securities Act of 1933. The designation does not impose on the person any duties, obligations or liability greater than those imposed on any other Audit Committee member or any other Director and does not affect the duties, obligations or liability of any other member of the Audit Committee or Board of Directors. Functions: The Audit Committee provides independent, objective oversight of the integrity of the Company’s financial statements, the Company’s compliance with legal and regulatory requirements, the independence and performance of the Company’s independent auditor as it performs audit, review or attest services, and the Company’s internal audit and control function. It selects and retains the independent registered public accounting firm, and reviews the plan and the results of the auditing engagement. It acts pursuant to a written charter that was reaffirmed by the Board of Directors in January 2018 and is attached as Exhibit A to the Proxy Statement for this 2018 Annual Meeting of Shareholders. Employee Benefits and Compensation Committee The Employee Benefits and Compensation Committee of the Board of Directors (the “Compensation Committee”) is comprised solely of Directors who are not current or former employees of Westamerica or any of its affiliates. They are independent as defined by NASDAQ rules. Functions: The Compensation Committee administers Westamerica Bancorporation’s 2012 Amended and Restated Stock Option Plan of 1995, Tax Deferred Savings and Retirement Plan, Deferred Profit Sharing Plan, Deferred Compensation Plan, and the Westamerica Bancorporation Deferral Plan. It administers the Company’s compensation programs and reviews and reports to the Board the compensation level for executive officers, including the CEO, of the Company and its subsidiaries and determines that compensation plans are balanced between financial results and prudent risk taking. The Compensation Committee determines annual corporate performance objectives for equity compensation and cash bonuses and their related corporate, divisional and individual goals. Based on the CEO’s assessment of the extent to which each executive officer met those objectives and goals, the Committee determines each executive officer’s annual equity compensation and cash bonus. The Compensation Committee also establishes the individual goals and targets for the CEO. All compensation approved by the Compensation Committee is reported to the full Board of Directors. The role of the Compensation Committee is described in greater detail under the section entitled “Compensation Discussion and Analysis.” The Compensation Committee is governed by a written charter as required by NASDAQ rules. The charter was reaffirmed by the Board of Directors in January 2017 and attached as Exhibit B to the Proxy Statement for the 2017 Annual Meeting of Shareholders. The Compensation Committee has the authority to seek assistance from officers and employees of the Company as well as external legal, accounting and other advisors. It has not retained outside consultants for compensation advice, but can request assistance on an as-needed basis. It does not delegate authority to anyone outside of the Compensation Committee. The Payroll and Employee Benefits Department supports the Compensation Committee by fulfilling certain administrative duties regarding the compensation programs. 1212 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y Nominating Committee The Board of Directors has determined that all members of the Nominating Committee are independent, as defined in NASDAQ rules. Functions: The Nominating Committee screens and recommends qualified candidates for Board membership. This Committee recommends a slate of nominees for each Annual Meeting. As part of that process, it evaluates and considers all candidates submitted by shareholders in accordance with the Company’s Bylaws, and considers each existing Board member’s contributions. The Committee applies the same evaluation standards whether the candidate was recommended by a shareholder or the Board. The Nominating Committee is governed by a written charter, which was reaffirmed January 27, 2016 and attached as Exhibit B to the Proxy Statement for the 2016 Annual Meeting of Shareholders. While the Board does not have a formal diversity policy, it broadly defines diversity to encompass a diverse range of skills and expertise sufficient to provide prudent guidance to the Company. In addition to the qualifications and characteristics described below, it considers whether the potential Director assists in achieving a mix of Board members that represents a diversity of background, perspective, and experience. Our Board includes Directors with experience in public corporations and non-profit organizations, as well as entrepreneurial individuals who have successfully run their own private enterprise. Our Board also has a broad set of skills necessary for providing oversight to a financial institution, which includes proven leadership, and expertise in capital management, finance, accounting, regulatory affairs, and investment management. Nominating Directors. The Nominating Committee will consider shareholder nominations submitted in accordance with Section 2.14 of the Bylaws of the Company. That section requires, among other things, that nominations be submitted in writing and must be received by the Corporate Secretary at least 45 days before the anniversary of the date on which the Company first mailed its proxy materials for the prior year’s Annual Meeting of Shareholders. If the date for the current year’s Annual Meeting changes more than 30 days from the date on which the prior year’s meeting was held, the Company must receive notice with a reasonable amount of time before the Company mails its proxy materials for the current year. Nominations must include the following information:  The principal occupation of the nominee;  The total number of shares of capital stock of the Company that the shareholder expects will be voted for the nominee;  The name and address of the nominating shareholder; and  The number of shares of capital stock of the Company owned by the nominating shareholder.

Compensation Discussion and Analysis The executive compensation practices described below have been followed consistently for twenty-five years. At each Annual Meeting of Shareholders since 2010, a majority of our shareholders approved an advisory proposal on the Company’s executive compensation. The Compensation Committee governs the executive compensation program that combines three compensation elements: base salary, annual non-equity cash incentives, and long-term stock grants. Several compensation philosophies and practices underlie this program:  Base salaries for participants in this program should be limited to foster an environment where incentive compensation motivates and rewards corporate, divisional, and individual performance.  Incentive compensation (annual non-equity cash incentives and long-term stock grants) is based on measurement of performance against pre-established objective measurable goals. Specific criteria for each objective are established for “threshold,” “target,” and “outstanding” performance. On any one measure, performance below “threshold” results in no credit for that objective. “Threshold” performance results in 75% achievement, “target” performance results in 100% achievement, and “outstanding” performance results in 150% achievement. The performance achievement level determines the size of incentive compensation awards.  Long-term incentive stock grants will be awarded to senior management if the corporate performance level is rated “threshold” or better. The purpose of long-term incentive grants is to: (1) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. 15 15 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 – Motivate senior management to focus on long-term performance; – Avoid excessive risk-taking and instill conservative management practices; – Build equity ownership among Westamerica’s senior management; – Link shareholder interests to management incentives; and – Create ownership mentality among senior management. In February 2013, the Board of Directors adopted a clawback policy that requires executive officers to forfeit previously awarded incentive compensation if the incentives were based on materially inaccurate financial statements or other performance measures that are later proven to be materially inaccurate or the achievement of which were due to fraud or other misconduct. Establishing Incentive Levels, Determining Objectives and Measuring Performance In administering the executive compensation program, the Compensation Committee determines “target” incentives for each position annually. The Compensation Committee exercises discretion in establishing “target” incentives in an effort to provide competitive pay practices while motivating and rewarding performance that benefits the Company’s long-term financial performance and shareholder interests, and avoids excessive risk-taking. At the beginning of each calendar year, the Compensation Committee establishes annual corporate performance objectives. In establishing corporate performance objectives, the Compensation Committee takes into consideration the current operating environment for the commercial banking industry as well as internal management policies and practices which would, in the Compensation Committee’s opinion, benefit the long-term interests of the Company and its shareholders. Corporate performance measures include risk management elements considered to be responsive to the impact that current operating conditions could have on the long-term performance of the Company. The Compensation Committee monitors the economy and the banking industry’s operating environment throughout the ensuing year, and may exercise discretion in adjusting corporate performance objectives during the year. The operating environment for the commercial banking industry is impacted by a myriad of factors including, but not limited to, local, national and global economic conditions, interest rate levels and trends, monetary policies of the Federal Reserve Board and its counterparts in other countries, fiscal policies of the United States government and other global political conditions, regulations and legislation, liquidity in capital markets, the demand for capital by commercial enterprises and consumers, new financial products, competitive response to changing conditions within the industry, trade balances, the changing values of real estate, currencies, commodities and other assets, and other factors. Management policies and practices the Board considers in establishing corporate performance objectives include, but are not limited to, management of the Company’s balance sheet and product pricing in a manner which will benefit the long-term financial interests of shareholders, the type and variety of financial products offered by the Company, adherence to internal controls, management of the credit risk of the Company’s loan and investment portfolios, the results of internal, regulatory and external audits, service quality delivered to the Company’s customers, service quality of “back office” support departments provided to those offices and departments directly delivering products and services to the Company’s customers, maintenance of operating policies and procedures which remain appropriate for risk management in a dynamic environment, timely and efficient integration of acquired companies, operational efficiencies, and capital management practices. Restricted performance shares (“RPS”) represent awards of Westamerica Bancorporation’s common stock subject to achievement of performance objectives established by the Compensation Committee. The 2012 Amended and Restated Stock Option Plan of 1995 (the “2012 Amended Plan”), which was originally approved by shareholders in 1616 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y 1995, and amended with shareholder approval in 2003 and again in 2012, defines the performance factors the Board must use in administering RPS grants as one or more of the following: earnings, diluted earnings per share, revenue and revenue per diluted share, expenses, share price, return on equity, return on equity relative to the average return on equity for similarly sized institutions, return on assets, return on assets relative to the average return on assets for similarly sized institutions, efficiency ratio (operating expenses divided by operating revenues), net loan losses as a percentage of average loans outstanding, nonperforming assets, and nonperforming assets as a percentage of total assets. In addition to establishing corporate performance objectives, the Compensation Committee also establishes individual goals for the CEO. In regard to the other executives named in the accompanying tables, the CEO recommends divisional and individual performance objectives to the Compensation Committee, which considers, discusses, adjusts as necessary, and adopts such performance objectives. Upon the closure of each calendar year, the Compensation Committee reviews corporate, divisional, and individual performance against the performance objectives for the year just completed. After thorough review and deliberation, the Compensation Committee determines the recommended amount of individual non-equity cash incentives and stock-based incentive awards. The Compensation Committee reports such incentives to the Board of Directors. Meetings of the Compensation Committee and Board of Directors routinely occur in January, immediately following the closure of the calendar year for which performance is measured for incentive compensation purposes. Stock Grants Long-term stock grants may only be awarded under shareholder approved stock-based incentive compensation plans. The Company’s Proxy Statement dated March 12, 2012, as filed with the SEC on March 13, 2012, summarizes the 2012 Amended Plan’s changes from the predecessor plan. Such changes included:  reducing the issuable shares to 1,500,000 (plus shares that become available if awards under prior plans expire unexercised or are cancelled, forfeited or terminated before being exercised);  any additional authorization of shares available for issuance must be approved by shareholders; and  establishing a plan expiration date of April 26, 2022 after which shareholder approval is again required to extend the term or approve a new stock option plan. The 2012 Amended Plan allows four types of stock-based compensation awards: Incentive Stock Options (“ISO”) allow the optionee to buy a certain number of shares of Westamerica Bancorporation common stock at a fixed price, which is established on the date of the option grant. ISOs are intended to meet the requirements of Section 422 of the Internal Revenue Code which provide advantages if certain conditions are met. If the optionee holds the acquired stock for the designated holding period, the optionee defers the timing of recognizing taxable income related to exercising the ISO. If the optionee complies with the ISO requirements, the Company does not receive a corporate tax deduction related to the shares issued. Nonqualified Stock Options (“NQSO”) also give the optionee the option to buy a certain number of shares of Westamerica Bancorporation common stock at a fixed price, which is established on the date of grant. Unlike ISOs, NQSOs do not allow deferral of taxable income for the optionee. At the time NQSOs are exercised, the optionee incurs taxable income equal to the spread between the exercise price and the market price of the stock, and the Company receives a corporate tax deduction in the same amount. Stock Appreciation Rights (“SAR”) provide the holder a cash payment equal to the difference between the fair market value of the Westamerica Bancorporation’s common stock on the date the SAR is surrendered and the fair market value of the Company’s common stock on the date the SAR was granted. The optionee incurs taxable 17 17 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 income at the time the SAR is settled and the Company receives a corporate tax deduction in the same amount. Restricted Performance Share Grants, as noted above, are awards of the Westamerica Bancorporation’s common stock that are subject to the achievement of performance objectives. Award recipients receive shares at the end of the performance measurement period only if performance objectives are achieved. The award recipient incurs taxable income at the time any RPS vests and the Company receives a corporate tax deduction in the same amount. Determination of Awards to Grant In determining which type of stock-based compensation awards to grant, the Compensation Committee considers the attributes of each form of incentive. Examples include the ability to motivate management to make decisions based on the long-term interests of shareholders, the desire to compensate with shares rather than cash, and the tax consequences of each type of award. The Compensation Committee retains the latitude to utilize all forms of incentives provided under the 2012 Amended Plan. In the current and preceding years, the Compensation Committee has utilized NQSO and RPS based on the motivational aspects of stock price appreciation, the settlement in shares rather than cash, and the preservation of tax deductions for the Company. As of February 26, 2018, the Company had no ISO or SAR awards outstanding. Determination of Option Exercise Price The 2012 Amended Plan also requires the exercise price of each NQSO or ISO to be no less than one hundred percent (100%) of the fair market value of the Company’s common stock on the date of grant. The 2012 Amended Plan does not allow re-pricing stock options for poor stock price performance. Stock-based compensation awards are submitted by the Compensation Committee to the full Board of Directors for review. As described above, these meetings have routinely occurred in January immediately following the closure of the calendar year for which performance is measured for incentive compensation purposes. The Compensation Committee meeting has routinely been held during the same week as the related Board of Directors meeting. These January meetings follow by no more than ten business days the Company’s public disclosure of its financial results for the preceding year. As a result, stock option grants are awarded, and the exercise price of such grants are determined at a time when the Company has broadly disseminated its financial condition and current operating results to the public. The Company’s outstanding stock option grants are dated, and related stock option exercise prices are determined, on the January date the Compensation Committee meets to approve such grants. Long-Term Incentive Attributes The Board of Directors has designated the Compensation Committee as the administrator of the 2012 Amended Plan. The Compensation Committee reports to the Board the terms and conditions of stock option awards. In carrying out this responsibility, the Compensation Committee designs such awards as long-term incentives. The terms and conditions of currently outstanding awards include:  NQSO grants vest one-third (1/3) on each anniversary of the grant date. As such, NQSO grants become fully vested over a three-year period. NQSO grants expire on the tenth anniversary of the grant date. The Company does not pay dividends on shares underlying NQSO grants until the optionee exercises the option and the shares are outstanding on a dividend record date.  RPS awards vest three years following the grant date, only if corporate performance objectives are achieved over the three-year period. The Company does not pay dividends on RPS shares until vesting occurs and shares awarded become outstanding on a dividend record date. 1818 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y Compensation for the Chairman, President & CEO Mr. Payne performs two functions for the Company. These two functions tend to be compensated separately at similarly sized banking institutions. Mr. Payne serves as Chairman of the Board and CEO with responsibilities including oversight of the organization and external strategic initiatives. Mr. Payne also serves as President and CEO with responsibilities including daily management of internal operations. Mr. Payne’s total compensation reflects these broad responsibilities. Consistent with the overall compensation philosophy for senior executives, Mr. Payne’s compensation has a greater amount of pay at risk through incentives than through base salary. Since Mr. Payne is compensated as an executive, he is not eligible to receive compensation as a Director. As noted on page 30 of the Proxy under the Pension Benefits Table, during 1997 the Company entered into a nonqualified pension agreement (“Pension Agreement”) with Mr. Payne in consideration of Mr. Payne’s agreement that RPS granted in 1995, 1996 and 1997 would be cancelled.(1) In entering the Pension Agreement, the Board of Directors considered the following:  Mr. Payne had a significant beneficial interest in Westamerica Bancorporation common stock, which was more than adequate to continue to provide motivation for Mr. Payne to continue managing the Company in the best interests of shareholders.  In 1997, the Company had consummated its largest acquisition, with significant total asset growth of approximately 51 percent. One of the Board’s objectives was to provide a compensation mechanism providing retention features for Mr. Payne. Retention of Mr. Payne as President and CEO was desired following the Company’s significant growth. The RPS shares surrendered for the Pension Agreement were scheduled to vest on dates in 1998, 1999 and 2000, while the Pension Agreement was not fully vested until December 31, 2002. Additionally, the 20-year certain pension provided under the Pension Agreement was to commence upon Mr. Payne’s attainment of age 55. Mr. Payne was age 42 at the time of entering the Pension Agreement. Compensation Awarded to Named Executive Officers Base salaries for participants in the executive compensation program are generally limited to foster an environment where incentive compensation motivates and rewards corporate, divisional, and individual performance. As such, base pay increases are generally infrequent and limited to “control points” assigned to each position. The non-equity cash incentive formula has the following components: "Target" Cash Incentive X Composite Corporate, Divisional and Individual Performance Level = Cash Incentive Award In structuring performance goals for the named executive officers, the Compensation Committee emphasizes goals, which if achieved, will benefit the overall Company. As such, senior management level positions have high relative weighting on corporate objectives, and divisional leadership positions also have significant weighting on divisional objectives. The “target” cash incentive and the weighting of goals for the named executive officers for 2017 performance were as follows: Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 (1) The value of the surrendered RPS shares and the Pension Agreement were considered equivalent based on actuarial assumptions. 19 19 “Target” Cash Incentive $371,000 107,200 82,500 73,900 60,500 Corporate 80% 55% 50% 55% 55% Goal Weighting Divisional – 25% 40% 25% 35% Individual 20% 20% 10% 20% 10% Mr. Payne Mr. Thorson Mr. Robinson(1) Mr. Hansen Mr. Rizzardi The Compensation Committee establishes corporate goals with the intent to balance current profitability with long- term stability of the Company and its future earnings potential. The 2017 corporate performance goals related to current year “profitability” included return on equity, return on assets and diluted earnings per share. The performance goals designed to maintain the long-term stability of the Company include “quality” and “control” components. The “quality” measures include loan portfolio quality measures (originated classified loans and other real estate owned, originated non-performing loans and originated other real estate owned, and net loan losses to average originated loans) and service quality measures (external service quality to customers and internal service quality of support departments and branches). The “control” measures include non-interest expense to revenues (efficiency ratio), the level of non-interest expenses, and internal audit results. By maintaining both current year “profitability” goals and longer-term “quality” and “control” goals, Management has a disincentive to maximize current earnings at the expense of longer-term results. For 2017, the Compensation Committee expected nominal economic growth with an uncertain interest rate environment., As a result, the Committee reserved the ability to exercise a certain degree of judgment in adjusting target goals based on the resulting operating environment. The Compensation Committee determined the 2017 operating environment was generally characterized as follows:  Growth in the United States’ economy increased slightly from the prior year, but growth was tempered;  Inflation remained below targets established by the Federal Open Market Committee in spite of continuing monetary policy accommodation and improving employment conditions;  The Federal Open Market Committee increased the federal funds rate on three occasions resulting in rising short-term interest rates; however, intermediate term interest rates did not begin to increase until late in the year;  Throughout most of 2017, competitive interest rates on loans remained below the yields required for the Company to deliver satisfactory financial results throughout a full business cycle;  Interest rates on investment securities remained relatively low compared to interest rates which would exist with moderated monetary policies and economic conditions;  Real estate values in the Company’s metropolitan geographies appeared to increase to levels above those which could be sustained by prevailing economic conditions; and  Regulations imposed on banks continued to pressure compliance costs, revenue opportunities, and increased operational risks. The Compensation Committee considered Management’s response to the current operating environment including:  Management maintained discipline in pricing loans for long-term financial results;  Management consistently maintained conservative loan underwriting practices to appropriately manage the Company’s exposure to credit risk; (1) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. 2020 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y  Management avoided higher-yielding longer-dated investment securities, maintaining an appropriately short duration bond portfolio to provide asset re-pricing opportunities in a rising interest rate environment;  Management increased the value of the Company’s deposit base by increasing checking and savings deposits and reducing time deposits;  Management reduced operating costs to offset market interest rate pressure on revenues;  Management maintained high levels of customer service; and  Management prudently managed capital enabling the Company to continue delivering increasing annual levels of dividends per share and position the Company for growth opportunities. The Compensation Committee chose to make adjustments to actual results to take into account the impact of the operating environment. Adjusted actual results against “target” performance goals were: Performance “Target” Adjusted Actual Results Profitability Goals: Return on average shareholders’ equity Return on average assets Diluted earnings per share 10.30% 1.09% $2.280 10.29% 1.10% $2.285 Quality Goals: Classified originated loans and other real estate owned Non-performing originated loans and other real estate owned Net loan losses to average originated loans Service quality Control Goals: Non-interest expense to revenues (efficiency ratio) Non-interest expenses Below satisfactory internal audits $40 million $18 million $11.0 million 0.15% Improving $6.6 million 0.08% Improving 51.0% $99.0 million none 50.4% $97.1 million none In reviewing the operating environment, Management’s response to the operating environment, and adjusted results compared to “target” performance goals, the Compensation Committee determined corporate performance to be 110.5% of target goals. As described above, divisional and individual goals are used in conjunction with corporate performance goals to determine cash bonus awards. In addition to daily management responsibilities, Mr. Payne’s individual goals included:  Manage the Company to achievement of financial goals including return on equity, return on assets, and earnings per share;  Maintain and improve credit quality in a manner prudent for the final stages of an economic expansion;  Achieving budgeted deposit growth goals;  Stabilizing loan volumes;  Satisfactory regulatory examinations and external and internal audit results;  Development of management succession plans;  Monitoring the development of sub-divisional employees;  Investor relations goals; and  Pursue mergers and acquisitions. 21 21 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 Based on individual performance against these goals, the Committee exercised its discretion and assigned Mr. Payne a composite corporate and individual performance level of 61%. In addition to routine on-going divisional responsibilities, Mr. Thorson managed the Finance Division toward functional goals, which included:  Manage the level of earning assets to achieve desired financial results;  Manage the investment securities portfolio in anticipation of rising interest rates: maximize yield while meeting duration objectives and maintaining high credit quality;  Monitor market rates on depository products and meet low-cost funding objective;  Manage the process of adopting new accounting standards;  Manage the Trust Department toward achieving fee growth goals, maintaining satisfactory audit results, and achieving personnel development objectives;  Provide management oversight to the Regulatory Compliance Department;  Develop personnel to foster business continuity;  Implement upgrades to functional operational systems;  Managing operating units to deliver superior customer service; and  Satisfactory regulatory examinations, external audits, and internal audits with all areas of responsibility. Based on the Finance Division’s results, the Committee determined divisional performance to be 116%. In addition to daily management responsibilities, Mr. Thorson’s individual goals included:  Support cross-divisional regulatory compliance initiatives;  Monitor federal tax reform legislation and implement the impact of enacted legislation on the Company’s financial position and operating results, and other operational and administrative impacts;  Solicit shareholder votes which support the Board of Directors proxy recommendations;  Management of Bank and Company level capital positions; and  Provide financial management support to potential merger and acquisitions activities. Based on individual performance against these goals, the Committee determined Mr. Thorson’s individual performance to be 138%. In considering all elements of performance, the Committee exercised its discretion and assigned Mr. Thorson a composite corporate, divisional and individual performance level of 146%. In addition to routine on-going divisional responsibilities, Mr. Robinson(1) managed the Banking Division toward functional goals, which included:  Achievement of deposit goals;  Stabilization of Banking Division loan volumes;  Achievement of Community Development loan objectives;  Delivering superior customer service throughout the branching system; and  Satisfactory branch audit results. Based on the Banking Division’s results, the Committee determined divisional performance to be 100%. In addition to daily management responsibilities, Mr. Robinson’s individual goals included:  Regional sales management responsibilities;  Coach and mentor subordinates to higher levels of performance; (1) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. 2222 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y  Outbound customer calling activities;  Leadership in the career development initiatives; and  Management of service quality standards within the Banking Division. Based on individual performance against these goals, the Committee determined Mr. Robinson’s individual performance to be 138%. In considering all elements of performance, the Committee exercised its discretion and assigned Mr. Robinson a composite corporate, divisional and individual performance level of 133%. In addition to routine on-going divisional responsibilities, Mr. Hansen managed the Operations and Systems Division toward functional goals, which included:  Maintain and improve customer service quality;  Meet or exceed non-interest expense goals;  Satisfactory risk management as measured by the results of internal, third-party and regulatory examinations;  Installation of new and upgraded systems;  Management and satisfactory completion of information technology projects; and  Improvements in divisional compliance programs. Based on the Operations and Systems Division’s results, the Committee determined divisional performance to be 118%. In addition to daily management responsibilities, Mr. Hansen’s individual goals included:  Managerial oversight of marketing and merchant processing services functions;  Management of divisional internal controls and risks;  Satisfactory audit results; and  Meeting staff development objectives to position the Company for internal growth. Based on individual performance against these goals, the Committee determined Mr. Hansen’s individual performance to be 138%. As a result, Mr. Hansen’s composite corporate, divisional and individual performance level was 118%. In addition to routine on-going divisional responsibilities, Mr. Rizzardi managed the Credit Division toward functional goals, which included:  Maintain loan underwriting standards to ensure stable to improving credit quality;  Maintain credit quality as measured by net loan charge-offs, levels of non-performing loans and other real estate owned, and delinquent loans;  Manage staff to production objectives in commercial loan underwriting offices;  Meet divisional compliance responsibilities;  Delivery of superior customer service; and  Satisfactory internal audit, loan review and regulatory examination results. Based on the Credit Division’s results, the Committee determined divisional performance to be 108%. In addition to daily management responsibilities, Mr. Rizzardi’s individual goals included:  Progress in meeting staff development initiatives; and  Manage divisional compliance projects. Based on individual performance against these goals, the Committee determined Mr. Rizzardi’s individual 23 23 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 performance to be 97%. As a result, Mr. Rizzardi’s composite corporate, divisional and individual performance level was 108%. Based on the above described performance against objectives, the Committee determined cash incentive awards as follows: “Target” Cash Incentive $371,000 107,200 82,500 73,900 60,500 Mr. Payne Mr. Thorson Mr. Robinson(1) Mr. Hansen Mr. Rizzardi X Composite Corporate Divisional and Individual Performance Level = 61% 146% 133% 118% 108% Cash Incentive Award $225,000 156,200 109,900 86,900 65,400 The size of stock grants is determined by corporate performance using stated formulas. The formulas used to determine “target” NQSO and RPS grant sizes adjust for changes in the underlying value of one share of Westamerica Bancorporation common stock. For achievement of corporate performance in 2017, the following stock grants were awarded in January 2018: “Target” Nonqualified Stock Option Grant – 19,095 – 17,285 15,385 “Target” RPS Grant – 1,801 – 1,620 1,457 X X Corporate Performance Level 110.5% 110.5% 110.5% 110.5% 110.5% Corporate Performance Level 110.5% 110.5% 110.5% 110.5% 110.5% = Nonqualified Stock Option Award – 21,100 – 19,100 17,000 = RPS Award – 1,990 – 1,790 1,610 Mr. Payne Mr. Thorson Mr. Robinson(2) Mr. Hansen Mr. Rizzardi Mr. Payne Mr. Thorson Mr. Robinson(3) Mr. Hansen Mr. Rizzardi RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved over the three-year period. In January 2018, the Compensation Committee evaluated whether the three year corporate performance objectives were met for RPS awards granted in January 2015. The performance objectives for the RPS granted in January 2015 included:  3 year cumulative diluted earnings per share (EPS); (1) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. (2) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. As such, no NQSO were granted to Mr. Robinson. (3) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. As such, no RPS were granted to Mr. Robinson. 2424 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y  3 year average of annual return on average total assets (ROA);  3 year average of annual return on average shareholders’ equity relative to industry average ROE (ROE differential);  Ending originated non-performing assets to total originated assets (NPA); and  Efficiency ratio over three years. The RPS would vest if any one of the following performance results were achieved:  4 of 5 objectives reaching “threshold” performance level;  3 of 5 objectives reaching “target” performance level; or  2 of 5 objectives reaching “outstanding” performance level. The goals and achieved results were: EPS ROA ROE differential NPA Efficiency Ratio Threshold $6.75 1.10% 1.00% 0.50% 56.00% Target $6.85 1.14% 1.50% 0.35% 55.00% Outstanding $6.95 1.18% 2.30% 0.25% 53.00% Result Target Threshold Target Outstanding Outstanding With five of the goals achieving the “threshold” performance level or better, the Compensation Committee determined the RPS shares awarded in 2015 vested upon achievement of three year goals. Nonqualified Deferred Compensation Programs The Company maintains nonqualified deferred compensation programs to provide senior and mid-level executives the ability to defer compensation in excess of the annual limits imposed on the Company’s ESOP plan. The Company believes these tax deferral programs enhance loyalty and motivate retention of executives. These programs allow executives to defer cash pay and RPS shares upon vesting. The programs also allow Directors to defer Director fees.  Cash pay deferred in the program accumulates in accounts in the names of the participating Directors and executives. The Company credits the balance of these accounts with interest using an interest rate that approximates the crediting rate on corporate-owned life insurance policies, under which Directors and executives are the named insured. Deferrals and interest credits represent general obligations of the Company.  The common stock the Company issues to executives upon the vesting of RPS grants may be deferred into the program and deposited into a “Rabbi Trust.” Since these shares are outstanding shares of the Company’s common stock, the Company pays dividends on these shares at the same rate paid to all shareholders. The shares held in the “Rabbi Trust” are subject to claims by the Company’s creditors. Employment Contracts None of the executives named in the accompanying tables have employment contracts with the Company. Compensation in the Event of a Change in Control The banking industry has significant merger and acquisition activity. To promote retention of senior executives, unvested NQSO and RPS grants contain a “change in control” provision, which trigger full vesting upon a change in control. The Compensation Committee determined these provisions were appropriate in order to retain executives to continue managing the Company after any “change in control” was announced through its ultimate consummation. Since none of the named executive officers have entered employment contracts with the Company, they serve in an 25 25 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 “at-will” capacity and could terminate their employment at any time. The Compensation Committee felt it would be in the best interests of shareholders to have a retention mechanism in place to provide continuity of management during a “change in control” process. Further, the Committee expects the named executive officers would be terminated by an acquiring institution rather than retained in a similar functional capacity. The Company also maintains a Severance Payment Plan covering all employees to promote employee retention. The Severance Payment Plan provides salary continuation benefits for employees in the event of a “change in control.” The amount of salary continuation benefits is based on years of service and corporate title, but in no event exceed the equivalent of one times annual salary. All named executive officers are eligible for one year’s salary under the plan. Other Internal Revenue Code (“IRC”) Section 162(m) places a limit on the amount of compensation that may be deducted by the Company in any year with respect to certain of the Company’s highest-paid executives. Prior to enactment of the Tax Cuts and Jobs Act of 2017 (the “Act”), certain “performance-based compensation” was not counted toward this limit. The Act eliminated the “performance-based compensation” exemption. The Company intends generally to qualify compensation paid to executive officers for deductibility under the IRC but reserves the right to pay compensation that is not deductible. Employee Benefits Compensation Committee Report We, the Compensation Committee of the Board of Directors of the Company, have reviewed and discussed the Compensation Discussion and Analysis with Management. Based on that review and discussion, we have recommended to the Board of Directors inclusion of the Compensation Discussion and Analysis in this Proxy Statement and the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Submitted by the Employee Benefits and Compensation Committee Patrick D. Lynch, Chairman Etta Allen Arthur C. Latno, Jr. Ronald A.

Pay Ratio Disclosure In August 2015 pursuant to a mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Securities and Exchange Commission adopted a rule requiring annual disclosure of the ratio of the median employee’s annual total compensation to the total annual compensation of the principal executive officer (“PEO”). The Company’s PEO is Mr. Payne. 27 27 Median Employee total annual compensation Mr. Payne total annual compensation Ratio of PEO to Median Employee Compensation $ 38,387 $615,031 16.0:1.0 In determining the median employee total annual compensation, the Company prepared a census of all employees as of December 31, 2017, who were employed for the full 2017 calendar year. For simplicity, the value of benefits provided by the Company’s qualified retirement plans and welfare benefit plans were excluded from the determination of total annual compensation as all employees are offered the same benefit programs.

Payne Non-Qualified Pension Agreement $4,861,948 $511,950 During 1997, the Company entered into a nonqualified pension agreement with Mr. Payne in consideration of Mr. Payne’s agreement that RPS awards granted in 1995, 1996 and 1997 would be cancelled. In January 2000, the Compensation Committee, based on the Company’s achievement of certain performance goals which had first been established for Mr. Payne’s 1995, 1996 and 1997 RPS awards, determined Mr. Payne’s annual pension would be $511,950. The pension commenced in 2010 and will be paid to Mr. Payne for 20 years. The discount rate used to determine the present value is 3.99%. The obligation is an unfunded general obligation of the Company. Nonqualified Deferred Compensation Table For Fiscal Year 2017 Name David L. Payne John "Robert" A. Thorson David L.

Non-equity incentive plan compensation deferred in 2017 was earned in 2016 and disclosed as compensation in the Summary Compensation Table for 2016 and is therefore excluded from the Summary Compensation Table for Fiscal Year 2017. (2) Includes change in value of deferred RPS shares, dividends earned on deferred RPS shares, and interest earned on deferred cash compensation. The amounts included in the Summary Compensation Table for Fiscal Year 2017 on page 27 are as follows: Messrs. Thorson - $42,431; Robinson - $36,094; Hansen - $28,092. (3) Includes dividends paid on deferred RPS shares. (4) Aggregate balance of deferred compensation reported as compensation prior to 2017 is as follows: Messrs. Thorson - $1,854,512; Robinson - $2,783,960; Hansen - $2,154,514. (5) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. Under the Westamerica Bancorporation and Subsidiaries Deferred Compensation Plan (the “Deferred Compensation Plan”), Directors and Officers may defer up to 100% of their Director’s compensation, salary and/or non-equity incentive compensation (cash bonus) into a non-qualified, unfunded deferred compensation program. The interest rate paid during 2017 was 5.0%. The interest rate may be changed annually. Interest is compounded semi-monthly. Participants choose in advance from the following distribution commencement dates: termination of employment, January 1 following termination of employment, or a specific date at least five years from date of deferral. Payment is made in a lump sum unless the participant chooses a four year, five year or ten year annual installment. Under the Westamerica Bancorporation Deferral Plan, 100% of vested RPS grants may be deferred. Dividends paid on such issued and outstanding shares are paid in cash to the deferral participants, and are paid at the same 3030 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y rate as is paid to all other shareholders. The distribution of deferred RPS shares occurs at least two years after deferral, one month following termination, or the January 1 immediately following termination as elected by the participant at the time of deferral. If the participant is one of the named executive officers, benefit distributions that are made upon termination of employment may not start earlier than six months after the date of termination. Potential Payments Upon Termination or Change in Control Payments to be made to the named executive officers in the event of termination of employment or change in control are described below. Termination Vested NQSOs may be exercised within 90 days of termination and within one year of death or disability. RPS shares vest if the Compensation Committee determines performance goals are met. Terminated employees will receive vested RPS shares if the settlement date of the RPS grant occurs within 90 days of termination. Employees separating from service due to death, disability or retirement are eligible to receive a pro rata portion of granted RPS shares if the Compensation Committee determines that the performance goals are likely to be met for the grant period. The pro rata basis is determined by the number of full years of the vesting period completed before date of death, disability or retirement. Deferred compensation account balances are distributed on January 1 following termination, or a specific date at least five years from the date of deferral in the form of annual payments over four years. Payment may also be made in a lump sum or in annual payments for five or 10 years as elected by the participant at the time of deferral. If the participant is one of the named executive officers, benefit distributions that are made upon termination of employment may not start earlier than six months after the date of termination. Change in Control A change in control is defined under the 2012 Amended Plan as shareholder approval of a dissolution or liquidation of the Company or a sale of substantially all of the Company’s assets to another company, or a tender offer for 5% or more of the Company’s outstanding common stock or a merger in which the Company’s shareholders before the merger hold less than 50% of the voting power of the surviving company after the merger. In the event of a change in control, unvested NQSOs and RPS shares immediately vest. The value of in-the-money options and RPS shares subject to accelerated vesting for each of the named executive officers is as follows: Messrs. Payne: $0; Thorson: $991,902; Robinson(1): $997,399; Hansen: $892,637; and Rizzardi(2) $804,217. The value is computed by multiplying the difference between the market value on December 29, 2017, the last business day of 2017, and the exercise price of each option by the number of shares subject to accelerated vesting. Under the Company’s Severance Payment Plan, executive officers receive six week’s pay for every year or partial year of service up to one year’s base salary (see Summary Compensation Table for Fiscal Year 2017 for annual base salary for all named executive officers). All named executive officers have met the service requirement for one year’s base salary. Severance pay is paid in a lump sum or on a semi-monthly basis at the discretion of the Company. The Severance Payment Plan is subject to Section 409A of the Internal Revenue Code. (1) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. (2) Mr. Rizzardi’s compensation is subject to garnishments and liens pursuant to certain domestic relations orders. 31 31 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 Certain Relationships and Related Party Transactions In accordance with the Audit Committee Charter, the Audit Committee is responsible for reviewing and approving or disapproving all related party transactions required to be disclosed by Item 404 of Regulation S-K for potential conflicts of interest. The Company is also required by NASDAQ Rule 5250(b)(3) to disclose all agreements and arrangements between any director or nominee for director, and any person or entity other than the Company (the “Third Party”), relating to compensation or other payment in connection with such person’s candidacy or service as a director of the Company. The Company is not aware of any such agreements. Additionally, the Company’s Code of Conduct and Ethics provides rules that restrict transactions with affiliated persons. Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries of the Company in the ordinary course of business. With the exception of the Company’s Employee Loan Program, all outstanding loans and commitments included in such transactions were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons not related to the Company, did not involve more than a normal risk of collectability, and did not present other favorable features. As part of the Employee Loan Program, all employees, including executive officers, are eligible to receive mortgage loans with interest rates one percent (1%) below Westamerica Bank’s prevailing interest rate at the time of loan origination. Westamerica Bank makes all loans to executive officers under the Employee Loan Program in compliance with the applicable restrictions of Section 22(h) of the Federal Reserve Act. Messrs. Payne, Thorson, and Hansen have mortgage loans through this Program. The largest aggregate amount of principal during 2017 was $384,877, $267,611, and $214,079, respectively. The principal amount outstanding at December 31, 2017 was $367,495, $254,253, and $0, respectively. The amount of principal paid during 2017 was $17,382, $13,358, and $214,079, respectively. The amount of interest paid during 2017 was $8,825, $6,215, and $825, respectively. The rate of interest payable on the loans is 2.875%, 3.125%, and 0%, respectively. PROPOSAL 2 – APPROVE A NON-BINDING ADVISORY VOTE ON THE COMPEN- SATION OF OUR NAMED EXECUTIVE OFFICERS Background The 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires that shareholders cast a non-binding advisory vote on the executive compensation paid to the executive officers listed in the Summary Compensation Table (a so-called “say on pay” vote) as well as an advisory vote with respect to whether future say on pay votes will be held every one, two or three years. The result of the shareholder vote on the proposal to determine the frequency of future say on pay proposals was that shareholders should review executive compensation annually. Therefore, Proposal 2 requests that shareholders again approve the compensation paid to our named executive officers. Last year 99% of the shares voting on this proposal voted to support our Corporation’s executive compensation strategy. The proposal to determine how often the say on pay proposal should be voted on by shareholders will again be brought to a shareholder vote in 2022. We believe that our compensation policies and procedures are centered on a pay-for-performance culture and are strongly aligned with the long-term interests of our shareholders. Our incentive compensation plan provides for the grant of incentive stock options, non-qualified stock options, stock appreciation rights, and restricted performance shares. The Summary Compensation Table shows very stable base salaries indicative of our greater emphasis on performance-based stock and non-stock awards. Our stock and option awards are based on a minimum achievement of meeting the “threshold” level for each pre-established objective. Both awards have a three-year vesting period. Our annual incentive plan incorporates at least four financial and/or strategic 3232 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y performance metrics in order to properly balance risk with the incentives to drive our key annual financial and/or strategic initiatives; in addition, the annual incentive program incorporates a 150% maximum payout to further manage risk and the possibility of excessive payments. In 2003, shareholders approved the Company’s 2003 Amended Plan to include the following changes:  Disallowing re-pricing stock options for poor stock performance;  Limiting the number of shares that may be awarded; and  Requiring the Compensation Committee to meet the definition of independence to enable any award intended to qualify as “performance-based compensation” to meet Section 162(m) of the Internal Revenue Code. In 2009, shareholders re-approved the performance criteria for performance-based awards under the 2003 Amended Plan. In 2012, shareholders approved the Company’s 2012 Amended and Restated Stock Option Plan of 1995. The 2012 Amended Plan includes the following changes:  Reduced the number of shares available for future issuance from 4,307,593 to 1,500,000 (plus shares that become available if awards under prior plans expire unexercised or are cancelled, forfeited or terminated before being exercised; and  Extended the term of the 2012 Amended Plan to April 26, 2022 from April 24, 2013. Vote Required The “say on pay” proposal gives you as a shareholder the opportunity to endorse or not endorse our executive pay program through the following resolution: “Resolved, that the shareholders approve, on an advisory basis, the compensation of the named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, which disclosure includes the compensation discussion and analysis, the compensation tables and any related footnotes and narratives in the Company’s proxy statement for the Annual Meeting of Shareholders.” Because your vote is advisory, it will not be binding on the Board or create or imply any additional fiduciary duty by the Board. However, the Compensation Committee may take into account the outcome of the vote when considering future executive compensation arrangements. THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT PURSUANT TO THE COMPENSATION DISCLOSURE RULES OF THE SECURITIES AND EXCHANGE COMMISSION Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 33 33 PROPOSAL 3 – RATIFY SELECTION OF INDEPENDENT AUDITOR Ratify Selection of Independent Auditor Action by the shareholders is not required by law in the appointment of independent auditors, but their appointment is submitted by the Audit Committee and the Board of Directors in order to give the shareholders an opportunity to present their views. If the proposal is approved, the Audit Committee, in its discretion, may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders. If the proposal to ratify the selection of Crowe Horwath LLP as the Company’s independent auditors is rejected by the shareholders, then the Audit Committee will reconsider its choice of independent auditors. A representative of Crowe Horwath LLP is expected to be present at the Annual Meeting and will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions. Audit Fees The aggregate fees billed to the Company by Crowe Horwath LLP with respect to services performed for fiscal 2017 and 2016 are as follows: Audit Fees (1) Audit related fees (2) Tax fees (3) All other fees Total _____________________ 2017 2016 $510,000 35,210 40,200 - $585,410 $510,000 34,450 39,000 - $583,450 (1) Audit fees consisted of fees billed by Crowe Horwath LLP for professional services rendered for the audit of the Company’s consolidated financial statements, reviews of the consolidated financial statements included in the Company’s quarterly reports on Form 10- Q, and the audit of the Company’s internal controls over financial reporting. The audit fees also relate to services such as consents and audits of mortgage banking subsidiaries. (2) Audit-related fees consisted of fees billed by Crowe Horwath LLP for audits of certain employee benefits plans. (3) Tax fees consisted of fees billed by Crowe Horwath LLP for the compilation and review of the Company’s tax returns. Preapproval Policies and Procedures The Audit Committee is responsible for the appointment, compensation, retention and oversight of the work of any public accounting firm engaged by the Company for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the Company. Any accounting firm appointed by the Company reports directly to the Audit Committee. The Audit Committee must preapprove all auditing services and permitted non-audit services by its independent auditors and the fees to be paid by the Company for these services, except for those fees qualifying for the “de minimis exception” which provides that the preapproval requirement for certain non-audit services may be waived if certain express standards and requirements are satisfied prior to completion of the audit under certain conditions. This exception requires that the aggregate amount of all such services provided constitutes no more than five percent of the total amount of revenue paid to the audit firm by the Company during the fiscal year in which the services are provided. This exception also requires that at the time of the engagement, the Company did not recognize such services to be non-audit services, and such services are promptly brought to the attention 3434 2 0 1 8 W E S T A M E R I C A B A N C O R P O R A T I O N P R O X Y of the Audit Committee and approved prior to the completion of the audit by the Audit Committee. During fiscal year 2017, there were no non-audit services that were provided using this exception. The Audit Committee may delegate to one or more members of the Audit Committee the authority to grant preapprovals of non-audit services and fees. In such event, the decisions of the member or members of the Committee regarding preapprovals are presented to the full Audit Committee at its next meeting. The Audit Committee preapproved 100% of all services performed on behalf of the Company by Crowe Horwath LLP during fiscal year 2017. THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE SELECTION OF CROWE HORWATH LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM AUDIT COMMITTEE REPORT The material in this report is not soliciting material and is not deemed filed with the SEC. It is not incorporated by reference in any of the Company’s filings under the Securities Act of 1933 or the Exchange Act, whether made in the past or in the future even if any of those filings contain any general incorporation language. The Audit Committee is composed of four Directors who are neither officers nor employees of the Company, and who meet the NASDAQ independence requirements for Audit Committee members. The Audit Committee selects, appoints and retains the Company’s independent auditors and is responsible for their compensation and oversight. In performing its functions, the Audit Committee acts only in an oversight capacity and necessarily relies on the work and assurances of the Company’s management, which has the primary responsibility for financial statements and reports, and of the independent auditors. The auditors express an opinion on the conformity of the Company’s annual financial statements to United States generally accepted accounting principles and on internal control over financial reporting. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited consolidated financial statements for the fiscal year 2017 and discussed them with Management and with Crowe Horwath, LLP, the Corporation’s independent registered public accountants. Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with generally accepted accounting principles. Management also represented that it performed an assessment of the effectiveness of internal control over financial reporting as of December 31, 2017, and that internal control over financial reporting was effective. The independent auditor discussed with the Audit Committee matters required to be discussed by Auditing Standard of the Public Accounting Oversight Board (PCAOB), including certain matters related to the conduct of an audit and to obtain certain information from the Audit Committee relevant to the audit. The auditors also provided to the Audit Committee the written disclosures and the letter from the independent auditors required by PCAOB standards. The Audit Committee discussed with auditors the firm’s independence. Based on the Audit Committee’s discussion with Management and the independent auditors, the Audit Committee’s review of the representations of Management and the Report of the Independent Auditors to the Audit Committee, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 for filing with the SEC. 35 35 Y X O R P N O I T A R O P R O C N A B A C I R E M A T S E W 8 1 0 2 Submitted by the Audit Committee Ronald A.

The Audit Committee shall prepare the report that the Securities and Exchange Commission (“SEC”) rules require be included in the Company’s annual proxy statement. While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the Audit Committee to plan or conduct audits, or to determine that the Company’s financial statements are complete and accurate and are in accordance with generally accepted accounting principles. This is the responsibility of management and the independent auditor. The function of the Audit Committee is oversight. Management is responsible for the preparation and integrity of the Company’s financial statements. Management is responsible for maintaining appropriate accounting and financial reporting policies and an appropriate internal control environment. Subject to appointment, review and oversight by the Audit Committee, the independent auditor is responsible for planning and conducting a proper audit of the Company’s internal control environment and of its annual financial statements, reviewing the Company’s quarterly financial statements prior to the filing of each quarterly report on Form 10-Q, and other procedures. The members of the Audit Committee shall meet the independence requirements of the Nasdaq Stock Market (“Nasdaq”) and the rules and regulations of the SEC.

A number of factors, some of which are beyond the Company’s ability to predict or control, could cause future results to differ materially from those contemplated. These factors include but are not limited to (1) the length and severity of difficulties in the global, national and California economies and the effects of government efforts to address those difficulties; (2) liquidity levels in capital markets; (3) fluctuations in asset prices including, but not limited to stocks, bonds, real estate, and commodities; (4) the effect of acquisitions and integration of acquired businesses; (5) economic uncertainty created by terrorist threats and attacks on the United States, the actions taken in response, and the uncertain effect of these events on the national and regional economies; (6) changes in the interest rate environment; (7) changes in the regulatory environment; (8) competitive pressure in the banking industry; (9) operational risks including a failure or breach in data processing or security systems or those of third party vendors and other service providers, including as a result of cyber attacks or fraud; (10) volatility of interest rate sensitive loans, deposits and investments; (11) asset/liability management risks and liquidity risks; (12) the effect of natural disasters, including earthquakes, hurricanes, fire, flood, drought, and other disasters, on the uninsured value of the Company’s assets and of loan collateral, the financial condition of debtors and issuers of investment securities, the economic conditions affecting the Company’s market place, and commodities and asset values; (13) changes in the securities markets and (14) the outcome of contingencies, such as legal proceedings.

BUSINESS PART I Westamerica Bancorporation (the “Company”) is a bank holding company registered under the Bank Holding Company Act of 1956, as amended (“BHCA”). Its legal headquarters are located at 1108 Fifth Avenue, San Rafael, California 94901. Principal administrative offices are located at 4550 Mangels Boulevard, Fairfield, California 94534 and its telephone number is (707) 863- 6000. The Company provides a full range of banking services to individual and commercial customers in Northern and Central California through its subsidiary bank, Westamerica Bank (“WAB” or the “Bank”). The principal communities served are located in Northern and Central California, from Mendocino, Lake and Nevada Counties in the north to Kern County in the south. The Company’s strategic focus is on the banking needs of small businesses. In addition, the Bank owns 100% of the capital stock of Community Banker Services Corporation (“CBSC”), a company engaged in providing the Company and its subsidiaries with data processing services and other support functions. The Company was incorporated under the laws of the State of California in 1972 as “Independent Bankshares Corporation” pursuant to a plan of reorganization among three previously unaffiliated Northern California banks. The Company operated as a multi-bank holding company until mid-1983, at which time the then six subsidiary banks were merged into a single bank named Westamerica Bank and the name of the holding company was changed to Westamerica Bancorporation. The Company acquired five banks within its immediate market area during the early to mid 1990’s. In April 1997, the Company acquired ValliCorp Holdings, Inc., parent company of ValliWide Bank, the largest independent bank holding company headquartered in Central California. Under the terms of all of the merger agreements, the Company issued shares of its common 2 - 2 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 stock in exchange for all of the outstanding shares of the acquired institutions. The subsidiary banks acquired were merged with and into WAB. These six aforementioned business combinations were accounted for as poolings-of-interests. During the period 2000 through 2005, the Company acquired three additional banks. These acquisitions were accounted for using the purchase accounting method. On February 6, 2009, Westamerica Bank acquired the banking operations of County Bank (“County”) from the Federal Deposit Insurance Corporation (“FDIC”). On August 20, 2010, Westamerica Bank acquired assets and assumed liabilities of the former Sonoma Valley Bank (“Sonoma”) from the FDIC. The County and Sonoma acquired assets and assumed liabilities were measured at estimated fair values, as required by FASB ASC 805, Business Combinations. At December 31, 2017, the Company had consolidated assets of approximately $5.5 billion, deposits of approximately $4.8 billion and shareholders’ equity of approximately $590 million. The Company and its subsidiaries employed 785 full-time equivalent staff as of December 31, 2017. The Company’s Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports as well as beneficial ownership reports on Forms 3, 4 and 5 are available through the SEC’s website (https://www.sec.gov). Such documents as well as the Company’s director, officer and employee Code of Conduct and Ethics are also available free of charge from the Company by request to: Westamerica Bancorporation Corporate Secretary A-2M Post Office Box 1200 Suisun City, California 94585-1200 Supervision and Regulation The following is not intended to be an exhaustive description of the statutes and regulations applicable to the Company’s or the Bank’s business. The description of statutory and regulatory provisions is qualified in its entirety by reference to the particular statutory or regulatory provisions. Moreover, major new legislation and other regulatory changes affecting the Company, the Bank, and the financial services industry in general have occurred in the last several years and can be expected to occur in the future. The nature, timing and impact of new and amended laws and regulations cannot be accurately predicted. Regulation and Supervision of Bank Holding Companies The Company is a bank holding company subject to the BHCA. The Company reports to, is registered with, and may be examined by, the Board of Governors of the Federal Reserve System (“FRB”). The FRB also has the authority to examine the Company’s subsidiaries. The Company is a bank holding company within the meaning of Section 3700 of the California Financial Code. As such, the Company and the Bank are subject to examination by, and may be required to file reports with, the Commissioner of the California Department of Business Oversight (the “Commissioner”). The FRB has significant supervisory and regulatory authority over the Company and its affiliates. The FRB requires the Company to maintain certain levels of capital. See “Capital Standards.” The FRB also has the authority to take enforcement action against any bank holding company that commits any unsafe or unsound practice, or violates certain laws, regulations or conditions imposed in writing by the FRB. Under the BHCA, the Company is required to obtain the prior approval of the FRB before it acquires, merges or consolidates with any bank or bank holding company. Any company seeking to acquire, merge or consolidate with the Company also would be required to obtain the prior approval of the FRB. The Company is generally prohibited under the BHCA from acquiring ownership or control of more than 5% of any class of voting shares of any company that is not a bank or bank holding company and from engaging directly or indirectly in activities other than banking, managing banks, or providing services to affiliates of the holding company. However, a bank holding company, with the approval of the FRB, may engage, or acquire the voting shares of companies engaged, in activities that the FRB has determined to be closely related to banking or managing or controlling banks. A bank holding company must demonstrate that the benefits to the public of the proposed activity will outweigh the possible adverse effects associated with such activity. The FRB generally prohibits a bank holding company from declaring or paying a cash dividend that would impose undue pressure on the capital of subsidiary banks or would be funded only through borrowing or other arrangements which might adversely affect a bank holding company’s financial position. Under the FRB policy, a bank holding company should not continue its existing rate 3 - 3 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K of cash dividends on its common stock unless its net income is sufficient to fully fund each dividend and its prospective rate of earnings retention appears consistent with its capital needs, asset quality and overall financial condition. See the section entitled “Restrictions on Dividends and Other Distributions” for additional restrictions on the ability of the Company and the Bank to pay dividends. Transactions between the Company and the Bank are restricted under Regulation W. The regulation codifies prior interpretations of the FRB and its staff under Sections 23A and 23B of the Federal Reserve Act. In general, subject to certain specified exemptions, a bank or its subsidiaries are limited in their ability to engage in “covered transactions” with affiliates: (a) to an amount equal to 10% of the bank’s capital and surplus, in the case of covered transactions with any one affiliate; and (b) to an amount equal to 20% of the bank’s capital and surplus, in the case of covered transactions with all affiliates. The Company is considered to be an affiliate of the Bank. A “covered transaction” includes, among other things, a loan or extension of credit to an affiliate; a purchase of securities issued by an affiliate; a purchase of assets from an affiliate, with some exceptions; and the issuance of a guarantee, acceptance or letter of credit on behalf of an affiliate. Federal regulations governing bank holding companies and change in bank control (Regulation Y) provide for a streamlined and expedited review process for bank acquisition proposals submitted by well-run bank holding companies. These provisions of Regulation Y are subject to numerous qualifications, limitations and restrictions. In order for a bank holding company to qualify as “well-run,” both it and the insured depository institutions which it controls must meet the “well capitalized” and “well managed” criteria set forth in Regulation Y. The Gramm-Leach-Bliley Act (the “GLBA”), or the Financial Services Act of 1999, repealed provisions of the Glass-Steagall Act, which had prohibited commercial banks and securities firms from affiliating with each other and engaging in each other’s businesses. Thus, many of the barriers prohibiting affiliations between commercial banks and securities firms have been eliminated. The BHCA was also amended by the GLBA to allow new “financial holding companies” (“FHCs”) to offer banking, insurance, securities and other financial products to consumers. Specifically, the GLBA amended section 4 of the BHCA in order to provide for a framework for the engagement in new financial activities. A bank holding company (“BHC”) may elect to become an FHC if all its subsidiary depository institutions are well capitalized and well managed. If these requirements are met, a BHC may file a certification to that effect with the FRB and declare that it elects to become an FHC. After the certification and declaration is filed, the FHC may engage either de novo or through an acquisition in any activity that has been determined by the FRB to be financial in nature or incidental to such financial activity. BHCs may engage in financial activities without prior notice to the FRB if those activities qualify under the list of permissible activities in section 4(k) of the BHCA. However, notice must be given to the FRB within 30 days after an FHC has commenced one or more of the financial activities. The Company has not elected to become an FHC. Regulation and Supervision of Banks The Bank is a California state-chartered Federal Reserve member bank and its deposits are insured by the FDIC. The Bank is subject to regulation, supervision and regular examination by the California Department of Business Oversight (“DBO”), and the FRB. The regulations of these agencies affect most aspects of the Bank’s business and prescribe permissible types of loans and investments, the amount of required reserves, requirements for branch offices, the permissible scope of its activities and various other requirements. In addition to federal banking law, the Bank is also subject to applicable provisions of California law. Under California law, the Bank is subject to various restrictions on, and requirements regarding, its operations and administration including the maintenance of branch offices and automated teller machines, capital requirements, deposits and borrowings, shareholder rights and duties, and investment and lending activities. In addition, the Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) imposes limitations on the activities and equity investments of state chartered, federally insured banks. FDICIA also prohibits a state bank from making an investment or engaging in any activity as a principal that is not permissible for a national bank, unless the Bank is adequately capitalized and the FDIC approves the investment or activity after determining that such investment or activity does not pose a significant risk to the deposit insurance fund. 4 - 4 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 On July 21, 2010, financial regulatory reform legislation entitled the "Dodd-Frank Wall Street Reform and Consumer Protection Act" (the "Dodd-Frank Act") was signed into law. The Dodd-Frank Act implemented far-reaching changes across the financial regulatory landscape, including provisions that, among other things:  Centralized responsibility for consumer financial protection by creating a new agency, the Consumer Financial Protection Bureau, responsible for implementing, examining and (as to banks with $10 billion or more in assets) enforcing compliance with federal consumer financial laws.  Restricted the preemption of state law by federal law and disallowed subsidiaries and affiliates of national banks from availing themselves of such preemption.  Applied the same leverage and risk-based capital requirements that would apply to insured depository institutions to most bank holding companies.  Required bank regulatory agencies to seek to make their capital requirements for banks countercyclical so that capital requirements increase in times of economic expansion and decrease in times of economic contraction.  Changed the assessment base for federal deposit insurance from the amount of insured deposits to consolidated assets less tangible capital, eliminated the ceiling on the size of the Deposit Insurance Fund ("DIF") and increased the floor of the size of the DIF. Imposed comprehensive regulation of the over-the-counter derivatives market, which would include certain provisions that would effectively prohibit insured depository institutions from conducting certain derivatives businesses in the institution itself.   Required large, publicly traded bank holding companies to create a risk committee responsible for the oversight of  enterprise risk management. Implemented corporate governance revisions, including with regard to executive compensation and proxy access by shareholders, that would apply to all public companies, not just financial institutions.  Made permanent the $250 thousand limit for federal deposit insurance.  Repealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts.  Amended the Electronic Fund Transfer Act ("EFTA") to, among other things, give the FRB the authority to establish rules regarding interchange fees charged for electronic debit transactions by payment card issuers having assets over $10 billion and to enforce a new statutory requirement that such fees be reasonable and proportional to the actual cost of a transaction to the issuer. While the Company’s assets are currently less than $10 billion, interchange fees charged by larger institutions may dictate the level of fees smaller institutions will be able to charge to remain competitive. Provisions in the legislation that affect the payment of interest on demand deposits and interchange fees may increase the costs associated with deposits as well as place limitations on certain revenues those deposits may generate. Capital Standards The federal banking agencies have risk-based capital adequacy guidelines intended to provide a measure of capital adequacy that reflects the degree of risk associated with a banking organization’s operations for both transactions resulting in assets being recognized on the balance sheet as assets, and the extension of credit facilities such as letters of credit and recourse arrangements, which are recorded as off balance sheet items. Under these guidelines, nominal dollar amounts of assets and credit equivalent amounts of off balance sheet items are multiplied by one of several risk adjustment percentages, which range from 0% for assets with low credit risk, such as certain U.S. government securities, to 1250% for assets with relatively higher credit risk, such as certain securitizations. A banking organization’s risk-based capital ratios are obtained by dividing its qualifying capital by its total risk-adjusted assets and off balance sheet items. The federal banking agencies take into consideration concentrations of credit risk and risks from nontraditional activities, as well as an institution’s ability to manage those risks, when determining the adequacy of an institution’s capital. This evaluation is made as a part of the institution’s regular safety and soundness examination. The federal banking agencies also consider interest rate risk (related to the interest rate sensitivity of an institution’s assets and liabilities, and its off balance sheet financial instruments) in the evaluation of a bank’s capital adequacy. As of December 31, 2017, the Company’s and the Bank’s respective ratios exceeded applicable regulatory requirements. See Note 9 to the consolidated financial statements for capital ratios of the Company and the Bank, compared to minimum capital requirements and for the Bank the standards for well capitalized depository institutions. On July 2, 2013, the Federal Reserve Board approved a final rule that implements changes to the regulatory capital framework for all banking organizations over a transitional period 2015 through 2018. 5 - 5 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K See the sections entitled “Capital Resources and Capital to Risk-Adjusted Assets” in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations for additional information. Prompt Corrective Action and Other Enforcement Mechanisms FDICIA requires each federal banking agency to take prompt corrective action to resolve the problems of insured depository institutions, including but not limited to those that fall below one or more prescribed minimum capital ratios. An institution that, based upon its capital levels, is classified as “well capitalized,” “adequately capitalized” or “undercapitalized” may be treated as though it were in the next lower capital category if the appropriate federal banking agency, after notice and opportunity for hearing, determines that an unsafe or unsound condition or an unsafe or unsound practice warrants such treatment. At each successive lower capital category, an insured depository institution is subject to more restrictions. In addition to measures taken under the prompt corrective action provisions, commercial banking organizations may be subject to potential enforcement actions by the federal banking agencies for unsafe or unsound practices in conducting their businesses or for violations of any law, rule, regulation or any condition imposed in writing by the agency or any written agreement with the agency. Safety and Soundness Standards FDICIA has implemented certain specific restrictions on transactions and required federal banking regulators to adopt overall safety and soundness standards for depository institutions related to internal control, loan underwriting and documentation, and asset growth. Among other things, FDICIA limits the interest rates paid on deposits by undercapitalized institutions, restricts the use of brokered deposits, limits the aggregate extensions of credit by a depository institution to an executive officer, director, principal shareholder or related interest, and reduces deposit insurance coverage for deposits offered by undercapitalized institutions for deposits by certain employee benefits accounts. The federal banking agencies may require an institution to submit an acceptable compliance plan as well as have the flexibility to pursue other more appropriate or effective courses of action given the specific circumstances and severity of an institution’s noncompliance with one or more standards. Federal banking agencies require banks to maintain adequate valuation allowances for potential credit losses. The Company has an internal staff that continually reviews loan quality and reports to the Board of Directors. This analysis includes a detailed review of the classification and categorization of problem loans, assessment of the overall quality and collectability of the loan portfolio, consideration of loan loss experience, trends in problem loans, concentration of credit risk, and current economic conditions, particularly in the Bank’s market areas. Based on this analysis, Management, with the review and approval of the Board, determines the adequate level of allowance required. The allowance is allocated to different segments of the loan portfolio, but the entire allowance is available for the loan portfolio in its entirety. Restrictions on Dividends and Other Distributions The Company’s ability to pay dividends to its shareholders is subject to the restrictions set forth in the California General Corporation Law (“CGCL”). The CGCL provides that a corporation may make a distribution to its shareholders if (i) the corporation’s retained earnings equal or exceed the amount of the proposed distribution plus unpaid accrued dividends (if any) on securities with a dividend preference, or (ii) immediately after the dividend, the corporation’s total assets equal or exceed total liabilities plus unpaid accrued dividends (if any) on securities with a dividend preference. The power of the board of directors of an insured depository institution to declare a cash dividend or other distribution with respect to capital is subject to statutory and regulatory restrictions which limit the amount available for such distribution depending upon the earnings, financial condition and cash needs of the institution, as well as general business conditions. FDICIA prohibits insured depository institutions from paying management fees to any controlling persons or, with certain limited exceptions, making capital distributions, including dividends, if, after such transaction, the institution would be undercapitalized. In addition to the restrictions imposed under federal law, banks chartered under California law generally may only pay cash dividends to the extent such payments do not exceed the lesser of retained earnings of the bank or the bank’s net income for its last three fiscal years (less any distributions to shareholders during this period). In the event a bank desires to pay cash dividends in excess of such amount, the bank may pay a cash dividend with the prior approval of the Commissioner in an amount not exceeding the greatest of the bank’s retained earnings, the bank’s net income for its last fiscal year or the bank’s net income for its current fiscal year. The federal banking agencies also have the authority to prohibit a depository institution or its holding company from engaging in business practices which are considered to be unsafe or unsound, possibly including payment of dividends or other payments under certain circumstances even if such payments are not expressly prohibited by statute. The Federal reserve Board has issued 6 - 6 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 guidance indicating its expectations that a bank holding company will inform and consult with Federal Reserve supervisory staff sufficiently in advance of (i) declaring and paying a dividend that could raise safety and soundness concerns (e.g., declaring and paying a dividend that exceeds earnings for the period for which the dividend is being paid); (ii) redeeming or repurchasing regulatory capital instruments when the bank holding company is experiencing financial weaknesses; or (iii) redeeming or repurchasing common stock or perpetual preferred stock that would result in a net reduction as of the end of the quarter in the amount of such equity instruments outstanding compared with the beginning of the quarter in which the redemption or repurchase occurred. Premiums for Deposit Insurance Substantially all of the deposits of the Bank are insured up to applicable limits by the DIF of the FDIC and are subject to deposit insurance assessments to maintain the DIF. The FDIC utilizes a risk-based assessment system that imposes insurance premiums based upon a risk matrix that takes into account a bank's capital level, asset quality and supervisory rating ("CAMELS rating"). In July 2010, Congress in the Dodd-Frank Act increased the minimum for the DIF reserve ratio, the ratio of the amount in the fund to insured deposits, from 1.15% to 1.35% and required that the ratio reach that level by September 30, 2020. Further, the Dodd-Frank Act made banks with $10 billion or more in assets responsible for the increase from 1.15% to 1.35%, among other provisions. In October 2010, the FDIC adopted a new DIF restoration plan to ensure the DIF reaching 1.35% by September 30, 2020. In assessing its progress in restoring the reserves, at least semi-annually, the FDIC updates its loss and income projections for the fund and, if needed, increases or decreases assessment rates, following notice-and-comment rulemaking, if required. In February 2011, the FDIC adopted a final rule effective April 1, 2011 to: (1) Redefine the deposit insurance assessment base from total domestic deposits to average total assets minus average tangible equity as required by the Dodd-Frank Act; (2) Change the deposit insurance assessment rates (which sets forth progressively lower assessment rate schedules that will take effect when the reserve ratio exceeds 1.15%, 2%, and 2.5%) ; (3) Implement the Dodd-Frank Act DIF dividend provisions; and (4) Revise the risk-based assessment system for all “large” and “highly complex” insured depository institutions. “Large” depository institutions are defined generally as having more than $10 billion in assets and "highly complex" institutions have over $50 billion in assets and are fully owned by a parent with over $500 billion in assets. The Bank is neither a “large” nor “highly complex” institution. In March, 2016, the FDIC issued a final rule to increase the DIF reserve ratio to the statutory minimum level of 1.35%, effective July 1, 2016, if the reserve ratio reached 1.15% before that date. In August, 2016, the FDIC announced the DIF reserve ratio surpassed the 1.15% reserve ratio target, triggering three major changes: (1) The decline in the range of initial assessment rates for all banks from 5-35 basis points to 3-30 basis points; (2) The assessment of a quarterly surcharge on large banks equal to an annual rate of 4.5 basis points in addition to regular assessments; and (3) A revised method to calculate risk-based assessment rates for established small banks (under $1 billion in assets) pursuant to an FDIC final rule issued April, 2016. The Company cannot provide any assurance as to the effect of any future changes in its deposit insurance premium rates. Community Reinvestment Act and Fair Lending Developments The Bank is subject to certain fair lending requirements and reporting obligations involving home mortgage lending operations and Community Reinvestment Act (“CRA”) activities. The CRA generally requires the federal banking agencies to evaluate the record of financial institutions in meeting the credit needs of their local communities, including low and moderate income neighborhoods. In addition to substantive penalties and corrective measures that may be required for a violation of certain fair lending laws, the federal banking agencies may take compliance with such laws and CRA into account when regulating and supervising other activities including merger applications. 7 - 7 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K Financial Privacy Legislation and Customer Information Security The GLBA, in addition to the previously described changes in permissible nonbanking activities permitted to banks, BHCs and FHCs, also required the federal banking agencies, among other federal regulatory agencies, to adopt regulations governing the privacy of consumer financial information. The Bank is subject to the FRB’s regulations in this area. The federal bank regulatory agencies have established standards for safeguarding nonpublic personal information about customers that implement provisions of the GLBA (the “Guidelines”). Among other things, the Guidelines require each financial institution, under the supervision and ongoing oversight of its Board of Directors or an appropriate committee thereof, to develop, implement and maintain a comprehensive written information security program designed to ensure the security and confidentiality of customer information, to protect against any anticipated threats or hazards to the security or integrity of such information, and to protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer. U.S.A. PATRIOT Act Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA Patriot Act”) is the International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001. It includes numerous provisions for fighting international money laundering and blocking terrorist access to the U.S. financial system. The goal of Title III is to prevent the U.S. financial system and the U.S. clearing mechanisms from being used by parties suspected of terrorism, terrorist financing and money laundering. The provisions of Title III of the USA Patriot Act which affect the Bank are generally set forth as amendments to the Bank Secrecy Act. These provisions relate principally to U.S. banking organizations’ relationships with foreign banks and with persons who are resident outside the United States. The USA Patriot Act does not impose any filing or reporting obligations for banking organizations, but does require certain additional due diligence and recordkeeping practices. Sarbanes-Oxley Act of 2002 The stated goals of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”) are to increase corporate responsibility, to provide for enhanced penalties for accounting and auditing improprieties at publicly traded companies and to protect investors by improving the accuracy and reliability of corporate disclosures pursuant to the securities laws. Sarbanes-Oxley generally applies to all companies, both U.S. and non-U.S., that file or are required to file periodic reports under the Securities Exchange Act of 1934 (the “Exchange Act”). Sarbanes-Oxley includes very specific additional disclosure requirements and corporate governance rules, required the SEC and securities exchanges to adopt extensive additional disclosure, corporate governance and other related rules and mandates further studies of certain issues. Sarbanes-Oxley represents significant federal involvement in matters traditionally left to state regulatory systems, such as the regulation of the accounting profession, and to state corporate law, such as the relationship between a board of directors and management and between a board of directors and its committees and public company shareholders. Sarbanes- Oxley addresses, among other matters: (i) independent audit committees for reporting companies whose securities are listed on national exchanges or automated quotation systems (the “Exchanges”) and expanded duties and responsibilities for audit committees; (ii) certification of financial statements by the chief executive officer and the chief financial officer; (iii) the forfeiture of bonuses or other incentive-based compensation and profits from the sale of an issuer’s securities by directors and senior officers in the twelve month period following initial publication of any financial statements that later require restatement; (iv) a prohibition on insider trading during pension plan blackout periods; (v) disclosure of off-balance sheet transactions; (vi) a prohibition on personal loans to directors and officers under most circumstances with exceptions for certain normal course transactions by regulated financial institutions; (vii) expedited electronic filing requirements related to trading by insiders in an issuer’s securities on Form 4; (viii) disclosure of a code of ethics and filing a Form 8-K for a change or waiver of such code; (ix) accelerated filing of periodic reports; (x) the formation of the Public Company Accounting Oversight Board (“PCAOB”) to regulate public accounting firms and the audit of public companies that are subject to the securities laws; (xi) auditor independence; (xii) internal control evaluation and reporting; and (xiii) various increased criminal penalties for violations of securities laws. Programs To Mitigate Identity Theft In November 2007, federal banking agencies together with the National Credit Union Administration and Federal Trade Commission adopted regulations under the Fair and Accurate Credit Transactions Act of 2003 to require financial institutions and other creditors to develop and implement a written identity theft prevention program to detect, prevent and mitigate identity theft in connection with certain new and existing accounts. Covered accounts generally include consumer accounts and other accounts that present a reasonably foreseeable risk of identity theft. Each institution’s program must include policies and procedures designed to: (i) identify indicators, or “red flags,” of possible risk of identity theft; (ii) detect the occurrence of red flags; (iii) 8 - 8 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 respond appropriately to red flags that are detected; and (iv) ensure that the program is updated periodically as appropriate to address changing circumstances. The regulations include guidelines that each institution must consider and, to the extent appropriate, include in its program. Pending Legislation Changes to state laws and regulations (including changes in interpretation or enforcement) can affect the operating environment of BHCs and their subsidiaries in substantial and unpredictable ways. From time to time, various legislative and regulatory proposals are introduced. These proposals, if codified, may change banking statutes and regulations and the Company’s operating environment in substantial and unpredictable ways. If codified, these proposals could increase or decrease the cost of doing business, limit or expand permissible activities or affect the competitive balance among banks, savings associations, credit unions and other financial institutions. The Company cannot accurately predict whether those changes in laws and regulations will occur, and, if those changes occur, the ultimate effect they would have upon our financial condition or results of operations. It is likely, however, that the current level of enforcement and compliance-related activities of federal and state authorities will continue and potentially increase. Competition In the past, the Bank’s principal competitors for deposits and loans have been major banks and smaller community banks, savings and loan associations and credit unions. To a lesser extent, competition was also provided by thrift and loans, mortgage brokerage companies and insurance companies. Other institutions, such as brokerage houses, mutual fund companies, credit card companies, and certain retail establishments have offered investment vehicles that also compete with banks for deposit business. Federal legislation in recent years has encouraged competition between different types of financial institutions and fostered new entrants into the financial services market. Legislative changes, as well as technological and economic factors, can be expected to have an ongoing impact on competitive conditions within the financial services industry. While the future impact of regulatory and legislative changes cannot be predicted with certainty, the business of banking will remain highly competitive. ITEM 1A. RISK FACTORS Readers and prospective investors in the Company’s securities should carefully consider the following risk factors as well as the other information contained or incorporated by reference in this Report. The risks and uncertainties described below are not the only ones facing the Company. Additional risks and uncertainties that Management is not aware of or focused on or that Management currently deems immaterial may also impair the Company’s business operations. This Report is qualified in its entirety by these risk factors. If any of the following risks actually occur, the Company’s financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of the company’s securities could decline significantly, and investors could lose all or part of their investment in the Company’s common stock. Market and Interest Rate Risk Changes in interest rates could reduce income and cash flow. The discussion in this Report under “Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations – Asset, Liability and Market Risk Management” and “- Liquidity and Funding” and “Item 7A Quantitative and Qualitative Disclosures About Market Risk” is incorporated by reference in this paragraph. The Company’s income and cash flow depend to a great extent on the difference between the interest earned on loans and investment securities and the interest paid on deposits and other borrowings, and the Company’s success in competing for loans and deposits. The Company cannot control or prevent changes in the level of interest rates which fluctuate in response to general economic conditions, the policies of various governmental and regulatory agencies, in particular, the Federal Open Market Committee of the FRB, and pricing practices of the Company’s competitors. Changes in monetary policy, including changes in interest rates, will influence the origination of loans, the purchase of investments, the generation of deposits and other borrowings, and the rates received on loans and investment securities and paid on deposits and other liabilities. 9 - 9 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K Changes in capital market conditions could reduce asset valuations. Capital market conditions, including liquidity, investor confidence, bond issuer credit worthiness, perceived counter-party risk, the supply of and demand for financial instruments, the financial strength of market participants, and other factors can materially impact the value of the Company’s assets. An impairment in the value of the Company’s assets could result in asset write-downs, reducing the Company’s asset values, earnings, and equity. The value of securities in the Company’s investment securities portfolio may be negatively affected by disruptions in securities markets The market for some of the investment securities held in the Company’s portfolio can be extremely volatile. Volatile market conditions may detrimentally affect the value of these securities, such as through reduced valuations due to the perception of heightened credit and liquidity risks. There can be no assurance that the declines in market value will not result in other than temporary impairments of these assets, which would lead to loss recognition that could have a material adverse effect on the Company’s net income and capital levels. The weakness of other financial institutions could adversely affect the Company. Financial services institutions are interrelated as a result of trading, clearing, counterparty, or other relationships. The Company routinely executes transactions with counterparties in the financial services industry, including brokers and dealers, commercial banks, investment banks, and other institutional clients. Many of these transactions expose the Company to credit risk in the event of default of the Company’s counterparty or client. In addition, the Company’s credit risk may be increased when the collateral the Company holds cannot be realized or is liquidated at prices not sufficient to recover the full amount of the secured obligation. There is no assurance that any such losses would not materially and adversely affect the Company’s results of operations or earnings. Shares of Company common stock eligible for future sale or grant of stock options could have a dilutive effect on the market for Company common stock and could adversely affect the market price. The Articles of Incorporation of the Company authorize the issuance of 150 million shares of common stock (and two additional classes of 1 million shares each, denominated “Class B Common Stock” and “Preferred Stock”, respectively) of which approximately 26.4 million shares of common stock were outstanding at December 31, 2017. Pursuant to its stock option plans, at December 31, 2017, the Company had outstanding options for 1.0 million shares of common stock, of which 469 thousand were currently exercisable. As of December 31, 2017, 930 thousand shares of Company common stock remained available for grants under the Company’s stock option plans. Sales of substantial amounts of Company common stock in the public market could adversely affect the market price of its common stock. The Company’s payment of dividends on common stock could be eliminated or reduced. Holders of the Company’s common stock are entitled to receive dividends only when, as and if declared by the Company’s Board of Directors. Although the Company has historically paid cash dividends on the Company’s common stock, the Company is not required to do so and the Company’s Board of Directors could reduce or eliminate the Company’s common stock dividend in the future. The Company could repurchase shares of its common stock at price levels considered excessive. The Company repurchases and retires its common stock in accordance with Board of Directors-approved share repurchase programs. At December 31, 2017, approximately 1.8 million shares remained available to repurchase under such plans. The Company has been active in repurchasing and retiring shares of its common stock when alternative uses of excess capital, such as acquisitions, have been limited. The Company could repurchase shares of its common stock at price levels considered excessive, thereby spending more cash on such repurchases as deemed reasonable and effectively retiring fewer shares than would be retired if repurchases were effected at lower prices. Risks Related to the Nature and Geographical Location of the Company’s Business The Company invests in loans that contain inherent credit risks that may cause the Company to incur losses. The Company can provide no assurance that the credit quality of the loan portfolio will not deteriorate in the future and that such deterioration will not adversely affect the Company. 10 - 10 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 The Company’s operations are concentrated geographically in California, and poor economic conditions may cause the Company to incur losses. Substantially all of the Company’s business is located in California. A portion of the loan portfolio of the Company is dependent on real estate. At December 31, 2017, real estate served as the principal source of collateral with respect to approximately 53% of the Company’s loan portfolio. The Company’s financial condition and operating results will be subject to changes in economic conditions in California. The California economy was severely affected by the recessionary period of 2008 to 2009. Much of the California real estate market experienced a decline in values of varying degrees. This decline had an adverse impact on the business of some of the Company’s borrowers and on the value of the collateral for many of the Company’s loans. Generally, the counties surrounding and near San Francisco Bay have recovered more soundly from the recent recession than counties in the California “Central Valley,” from Sacramento in the north to Bakersfield in the south. Approximately 22% of the Company’s loans are to borrowers in the California “Central Valley.” Economic conditions in California’s diverse geographic markets can be vastly different and are subject to various uncertainties, including the condition of the construction and real estate sectors, the effect of drought on the agricultural sector and its infrastructure, and the California state government’s budgetary and fiscal condition. The Company can provide no assurance that conditions in any sector or geographic market of the California economy will not deteriorate in the future and that such deterioration will not adversely affect the Company. The markets in which the Company operates are subject to the risk of earthquakes, fire storms and other natural disasters. All of the properties of the Company are located in California. Also, most of the real and personal properties which currently secure a majority of the Company’s loans are located in California. Further, the Company invests in securities issued by companies and municipalities operating throughout the United States, and in mortgage-backed securities collateralized by real property located throughout the United States. California and other regions of the United States are prone to earthquakes, brush and forest fires, flooding, drought and other natural disasters. In addition to possibly sustaining uninsured damage to its own properties, if there is a major earthquake, flood, drought, fire or other natural disaster, the Company faces the risk that many of its debtors may experience uninsured property losses, or sustained business or employment interruption and/or loss which may materially impair their ability to meet the terms of their debt obligations. A major earthquake, flood, prolonged drought, fire or other natural disaster in California or other regions of the United States could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. Adverse changes in general business or economic conditions could have a material adverse effect on the Company’s financial condition and results of operations. A sustained or continuing weakness or weakening in business and economic conditions generally or specifically in the principal markets in which the Company does business could have one or more of the following adverse impacts on the Company’s business:          a decrease in the demand for loans and other products and services offered by the Company; an increase or decrease in the usage of unfunded credit commitments; an increase or decrease in the amount of deposits; a decrease in non-depository funding available to the Company; an impairment of certain intangible assets, including goodwill; an increase in the number of clients and counterparties who become delinquent, file for protection under bankruptcy laws or default on their loans or other obligations to the Company, which could result in a higher level of nonperforming assets, net charge-offs, provision for loan losses, reduced interest revenue and cash flows, and valuation adjustments on assets; an impairment in the value of investment securities; an impairment in the value of life insurance policies owned by the Company; an impairment in the value of real estate owned by the Company. The 2008 - 2009 financial crisis led to the failure or merger of a number of financial institutions. Financial institution failures can result in further losses as a consequence of defaults on securities issued by them and defaults under contracts entered into with such entities as counterparties. The failure of institutions with FDIC insured deposits can cause the DIF reserve ratio to decline, resulting in increased deposit insurance assessments on surviving FDIC insured institutions. Weak economic conditions can significantly weaken the strength and liquidity of financial institutions. The Company’s financial performance generally, and in particular the ability of borrowers to pay interest on and repay principal of outstanding loans and the value of collateral securing those loans, are highly dependent upon the business environment in the 11 - 11 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K markets where the Company operates, in the State of California and in the United States as a whole. A favorable business environment is generally characterized by, among other factors, economic growth, healthy labor markets, efficient capital markets, low inflation, high business and investor confidence, and strong business earnings. Unfavorable or uncertain economic and market conditions can be caused by: declines in economic growth, high rates of unemployment, deflation, declines in business activity or consumer, investor or business confidence; limitations on the availability of or increases in the cost of credit and capital; increases in inflation; natural disasters; or a combination of these or other factors. Such business conditions could adversely affect the credit quality of the Company’s loans, the demand for loans, loan volumes and related revenue, securities valuations, amounts of deposits, availability of funding, results of operations and financial condition. Regulatory Risks Restrictions on dividends and other distributions could limit amounts payable to the Company. As a holding company, a substantial portion of the Company’s cash flow typically comes from dividends paid by the Bank. Various statutory provisions restrict the amount of dividends the Company’s subsidiaries can pay to the Company without regulatory approval. The Bank obtained regulatory approval for dividends paid to the Company in 2017. A reduction in subsidiary dividends paid to the Company could limit the capacity of the Company to pay dividends. In addition, if any of the Company’s subsidiaries were to liquidate, that subsidiary’s creditors will be entitled to receive distributions from the assets of that subsidiary to satisfy their claims against it before the Company, as a holder of an equity interest in the subsidiary, will be entitled to receive any of the assets of the subsidiary. Adverse effects of changes in banking or other laws and regulations or governmental fiscal or monetary policies could adversely affect the Company. The Company is subject to significant federal and state regulation and supervision, which is primarily for the benefit and protection of the Company’s customers and not for the benefit of investors. In the past, the Company’s business has been materially affected by these regulations. Laws, regulations or policies, including accounting standards and interpretations currently affecting the Company and the Company’s subsidiaries, may change at any time. Regulatory authorities may also change their interpretation of these statutes and regulations. Therefore, the Company’s business may be adversely affected by any future changes in laws, regulations, policies or interpretations or regulatory approaches to compliance and enforcement including future acts of terrorism, major U.S. corporate bankruptcies and reports of accounting irregularities at U.S. public companies. Additionally, the Company’s business is affected significantly by the fiscal and monetary policies of the federal government and its agencies. The Company is particularly affected by the policies of the FRB, which regulates the supply of money and credit in the United States of America. Among the instruments of monetary policy available to the FRB are (a) conducting open market operations in U.S. government securities, (b) changing the discount rates of borrowings by depository institutions, (c) changing interest rates paid on balances financial institutions deposit with the FRB, and (d) imposing or changing reserve requirements against certain borrowings by banks and their affiliates. These methods are used in varying degrees and combinations to directly affect the availability of bank loans and deposits, as well as the interest rates charged on loans and paid on deposits. The policies of the FRB may have a material effect on the Company’s business, results of operations and financial condition. Under long- standing policy of the FRB, a BHC is expected to act as a source of financial strength for its subsidiary banks. As a result of that policy, the Company may be required to commit financial and other resources to its subsidiary bank in circumstances where the Company might not otherwise do so. Following the most recent recession, the FRB has been providing vast amounts of liquidity into the banking system. The FRB has been purchasing large quantities of U.S. government securities, including agency-backed mortgage securities, increasing the demand for such securities thereby reducing interest rates. The FRB began reducing these asset purchase activities in the fourth quarter 2013 and the Federal Open Market Committee (“FOMC”) has been increasing the target range for the federal funds rate. On December 13, 2017, the FOMC raised the target range for the federal funds rate to 1¼ to 1½ percent, which could reduce liquidity in the markets and cause interest rates to rise, thereby increasing funding costs to the Bank, reducing the availability of funds to the Bank to finance its existing operations, and causing fixed-rate investment securities and loans to decline in value. 12 - 12 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 Federal and state governments could pass legislation detrimental to the Company’s performance. As an example, the Company could experience higher credit losses because of federal or state legislation or regulatory action that reduces the amount the Bank's borrowers are otherwise contractually required to pay under existing loan contracts. Also, the Company could experience higher credit losses because of federal or state legislation or regulatory action that limits or delays the Bank's ability to foreclose on property or other collateral or makes foreclosure less economically feasible. Federal, state and local governments could pass tax legislation causing the Company to pay higher levels of taxes. The FDIC insures deposits at insured financial institutions up to certain limits. The FDIC charges insured financial institutions premiums to maintain the Deposit Insurance Fund. The FDIC may increase premium assessments to maintain adequate funding of the Deposit Insurance Fund. The behavior of depositors in regard to the level of FDIC insurance could cause our existing customers to reduce the amount of deposits held at the Bank, and could cause new customers to open deposit accounts at the Bank. The level and composition of the Bank's deposit portfolio directly impacts the Bank's funding cost and net interest margin. Systems, Accounting and Internal Control Risks The accuracy of the Company’s judgments and estimates about financial and accounting matters will impact operating results and financial condition. The discussion under “Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies” in this Report and the information referred to in that discussion is incorporated by reference in this paragraph. The Company makes certain estimates and judgments in preparing its financial statements. The quality and accuracy of those estimates and judgments will have an impact on the Company’s operating results and financial condition. The Company’s information systems may experience an interruption or breach in security. The Company relies heavily on communications and information systems, including those of third party vendors and other service providers, to conduct its business. Any failure, interruption or breach in security of these systems could result in failures or disruptions in the Company’s data processing, accounting, customer relationship management and other systems. Communication and information systems failures can result from a variety of risks including, but not limited to, events that are wholly or partially out of the Company’s control, such as telecommunication line integrity, weather, terrorist acts, natural disasters, accidental disasters, unauthorized breaches of security systems, energy delivery systems, cyber attacks, and other events. Although the Company devotes significant resources to maintain and regularly upgrade its systems and processes that are designed to protect the security of the Company’s computer systems, software, networks and other technology assets and the confidentiality, integrity and availability of information belonging to the Company and its customers, there is no assurance that any such failures, interruptions or security breaches will not occur or, if they do occur, that they will be adequately corrected by the Company or its vendors. The occurrence of any such failures, interruptions or security breaches could damage the Company’s reputation, result in a loss of customer business, subject the Company to additional regulatory scrutiny, or expose the Company to litigation and possible financial liability, any of which could have a material adverse effect on the Company’s financial condition and results of operations. The Company’s controls and procedures may fail or be circumvented. Management regularly reviews and updates the Company’s internal control over financial reporting, disclosure controls and procedures, and corporate governance policies and procedures. The Company maintains controls and procedures to mitigate against risks such as processing system failures and errors, and customer or employee fraud, and maintains insurance coverage for certain of these risks. Any system of controls and procedures, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Events could occur which are not prevented or detected by the Company’s internal controls or are not insured against or are in excess of the Company’s insurance limits or insurance underwriters’ financial capacity. Any failure or circumvention of the Company’s controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on the Company’s business, results of operations and financial condition.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion addresses information pertaining to the financial condition and results of operations of Westamerica Bancorporation and subsidiaries (the “Company”) that may not be otherwise apparent from a review of the consolidated financial statements and related footnotes. It should be read in conjunction with those statements and notes found on pages 47 through 88, as well as with the other information presented throughout this Report. Critical Accounting Policies The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America and follow general practices within the banking industry. Application of these principles requires the Company to make certain estimates, assumptions, and judgments that affect the amounts reported in the financial statements and accompanying notes. These estimates, assumptions, and judgments are based on information available as of the date of the financial statements; accordingly, as this information changes, the financial statements could reflect different estimates, assumptions, and judgments. Certain accounting policies inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported. Estimates, assumptions and judgments are necessary when assets and liabilities are required to be recorded at fair value, when a decline in the value of an asset not carried on the financial statements at fair value warrants an impairment writedown or valuation reserve to be established, or when an asset or liability needs to be recorded contingent upon a future event. Carrying assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and the information used to record valuation adjustments for certain assets and liabilities are based either on quoted market prices or are provided by other third-party sources, when available. The most significant accounting policies followed by the Company are presented in Note 1 to the consolidated financial statements. These policies, along with the disclosures presented in the other financial statement notes and in this discussion, provide information on how significant assets and liabilities are valued in the financial statements and how those values are determined. Based on the valuation techniques used and the sensitivity of financial statement amounts to the methods, assumptions, and estimates underlying those amounts, Management has identified the allowance for loan losses accounting to be the accounting area requiring the most subjective or complex judgments, and as such could be most subject to revision as new information becomes available. A discussion of the factors affecting accounting for the allowance for loan losses and purchased loans is included in the “Loan Portfolio Credit Risk” discussion below. Net Income The Company reported net income of $50.0 million and diluted earnings per common share (“EPS”) of $1.89 in 2017. The 2017 results include adjustments to net deferred tax asset values triggered by enactment of the Tax Cuts and Jobs Act of 2017 which reduced EPS $0.48, recognition of a loss contingency which reduced EPS $0.12, and securities gains which increased EPS $0.18. The 2017 results compare to net income of $58.9 million or $2.29 EPS for the year ended December 31, 2016 and net income of $58.8 million or $2.30 EPS for the year ended December 31, 2015. The Company’s principal source of revenue is net interest and loan fee income, which represents interest and fees earned on loans and investment securities (“earning assets”) reduced by interest paid on deposits and other borrowings (“interest-bearing liabilities”). Market interest rates declined considerably following the recession of 2008 and 2009. Interest rates remained historically low through 2016 as the Federal Open Market Committee’s (“FOMC”) monetary policy was highly accommodative. During this period, Management avoided originating long-dated, low-yielding loans given the potential impact of such assets on forward earning potential; as a result, loans declined and investment securities increased. The changing composition of the earning assets and low market interest rates has pressured the net interest margin to lower levels. The FOMC’s first post-recession increase in the federal funds rate occurred in December 2015, although longer-term rates declined. The FOMC’s successive post- recession increases in the federal funds rate occurred between December 2016 and December 2017, although longer-term rates have not increased by a similar magnitude. The more recent increase in rates has resulted in competitive loan yields which are more appealing from a profitability perspective, in Management’s opinion. The funding of the Company’s earning assets is primarily customer deposits. The Company’s long-term strategy includes maximizing checking and savings deposits as these types of deposits are lower-cost and less sensitive to changes in interest rates compared to time deposits. The 2017 average volume of checking and savings deposits was 95 percent of average total deposits. The Company recognized a reversal of the provision for loan losses of $1.9 million in 2017. Credit quality improved during 2017 with nonperforming assets declining $4 million to $8 million at December 31, 2017. The Company’s net losses in 2017 were 19 - 19 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K 0.08% of average loan balances. These developments were reflected in Management’s evaluation of credit quality, the level of the provision for loan losses, and the adequacy of the allowance for loan losses at December 31, 2017. The Company presents its net interest margin and net interest income on an FTE basis using the current statutory federal tax rate. Management believes the FTE basis is valuable to the reader because the Company’s loan and investment securities portfolios contain a relatively large portion of municipal loans and securities that are federally tax exempt. The Company’s tax exempt loans and securities composition may not be similar to that of other banks. Therefore in order to reflect the impact of the federally tax exempt loans and securities on the net interest margin and net interest income for comparability with other banks, the Company presents its net interest margin and net interest income on an FTE basis. The Company’s significant accounting policies (see Note 1 (“Summary of Significant Accounting Policies”) to Financial Statements in the Company’s 2017 Form 10-K) are fundamental to understanding the Company’s results of operations and financial condition. The Company adopted the FASB ASU 2016-09, Improvements to Employee Share-Based Payment Accounting effective January 1, 2017. The 2017 results reflect the Company’s prospective adoption of ASU 2016-09; The 2017 income tax provision was $698 thousand lower than would have been under accounting standards prior to the adoption of ASU 2016-09. Components of Net Income Net interest and loan fee income (FTE) Reversal of (provision for) loan losses Noninterest income Noninterest expense Income before income taxes (FTE) Income taxes (FTE) Net income For the Years Ended December 31, 2017 2015 2016 ($ in thousands, except per share data) $144,118 1,900 56,628 (103,292) 99,354 (49,329) $50,025 $145,077 3,200 46,574 (101,752) 93,099 (34,246) $58,853 $148,258 - 47,867 (105,300) 90,825 (32,072) $58,753 Net income per average fully-diluted common share Net income as a percentage of average shareholders' equity Net income as a percentage of average total assets $1.89 8.39% 0.92% $2.29 10.85% 1.12% $2.30 11.32% 1.16% Comparing 2017 with 2016, net income decreased $8.8 million. Net interest and loan fee income (FTE) decreased in 2017 compared with 2016 mostly attributable to lower average balances of loans and lower net yield on those loans, partially offset by higher average balances of investments. The Company recorded a $1.9 million reversal of provision for loan losses in 2017 and a $3.2 million reversal of provision for loan losses in 2016, reflecting Management's evaluation of losses inherent in the loan portfolio. Noninterest income increased primarily due to gains on sale of securities of $8.0 million and higher merchant processing services fees, partially offset by lower service charges on deposit accounts. Noninterest expense increased due to a $5.5 million loss contingency and an impairment charge of tax credit investments, partially offset by reductions in professional fees and correspondent service charges. The tax provision (FTE) for 2017 was higher than in 2016 primarily due to a $12.3 million charge to re-measure the Company’s net deferred tax asset triggered by enactment of the Tax Cuts and Jobs Act of 2017. The 2017 income tax provision was $698 thousand lower than it would have been under accounting standards prior to the adoption of ASU 2016-09. Comparing 2016 with 2015, net income increased $100 thousand due to a reversal of provision for loan losses and lower noninterest expense, partially offset by lower net interest and fee income (FTE), lower noninterest income and higher income tax provision (FTE). The lower net interest and fee income (FTE) was primarily caused by lower average balances of loans, partially offset by higher average balances of investments and lower average balances of higher-costing time deposits. The Company recorded a reversal of the provision for loan losses of $3.2 million, reflecting Management's evaluation of losses inherent in the loan portfolio. Noninterest income decreased primarily due to reduced levels of service charges on deposit accounts, financial services commissions and other service fees, partially offset by higher debit card fees. Noninterest expense decreased mostly due to lower personnel expense, lower occupancy expense, and lower other operating expense, offset in part by higher legal fees. Income tax provision (FTE) increased in 2016 due to higher pretax income, declining tax preference items and lower tax credits. 20 - 20 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 Net Interest and Loan Fee Income (FTE) The Company's primary source of revenue is net interest income, or the difference between interest income earned on loans and investment securities and interest expense paid on interest-bearing deposits and other borrowings. Components of Net Interest and Loan Fee Income (FTE) 2017 For the Years Ended December 31, 2016 ($ in thousands) 2015 Interest and loan fee income Interest expense FTE adjustment Net interest and loan fee income (FTE) $133,836 (1,900) 12,182 $144,118 $134,051 (2,116) 13,142 $145,077 $136,529 (2,424) 14,153 $148,258 Net interest margin (FTE) 3.12% 3.24% 3.36% Comparing 2017 with 2016, net interest and loan fee income (FTE) decreased $959 thousand mostly due to lower average balances of loans (down $109 million) and lower net yield on those loans (down 0.16%), partially offset by higher average balances of investments (up $255 million). Comparing 2016 with 2015, net interest and loan fee income (FTE) decreased $3.2 million due to lower average balances of loans (down $194 million), partially offset by higher average balances of investments (up $255 million) and lower average balances of higher-costing time deposits (down $62 million). Loan volumes have declined due to payoffs and problem loan workout activities (such as chargeoffs, collateral repossessions and principal payments), particularly with purchased loans, and reduced volumes of loan originations. The Company did not take an aggressive posture relative to loan portfolio growth during the post-recession period of historically low interest rates. Management increased investment securities as loan volumes declined. The average balance of the investment securities portfolio increased from $2.8 billion in 2015 to $3.1 billion in 2016 and $3.3 billion in 2017. The Company has been purchasing shorter- duration investment securities with lower yields than longer-duration securities to increase liquidity. The Company’s high levels of liquidity will provide an opportunity to obtain higher yielding assets as market interest rates rise. Yields on interest-earning assets declined due to historically low interest rates prevailing in the market. The net interest margin (FTE) was 3.12% in 2017, 3.24% in 2016 and 3.36% in 2015. The volume of older-dated higher-yielding loans and securities declined due to principal maturities and paydowns. As the investment securities portfolio grew during the three years ended December 31, 2017, the investment securities portfolio generated an increasing portion of the interest income (FTE). Interest income (FTE) generated from investments represented 47.0% of total interest income (FTE) in 2015, 52.2% in 2016 and 57.0% in 2017. During the three years ended December 31, 2017, the net interest margin (FTE) was affected by low market interest rates and the changing composition of interest-earning assets. The Company has been replacing higher-cost funding sources with low-cost deposits and interest expense has declined to offset some of the decline in interest income. Interest expense has been reduced by lowering rates paid on interest-bearing deposits and borrowings by reducing the volume of higher-cost funding sources. Federal Home Loan Bank (“FHLB”) advances were repaid in January 2015. Average balances of time deposits declined $27 million in 2017 compared with 2016 while lower-cost checking and savings deposits grew 4% in the same period. Lower-cost checking and savings deposits accounted for 94.8% of total average deposits in 2017 compared with 94.1% in 2016 and 92.5% in 2015.

Average loan balances include nonperforming loans. Interest income includes reversal of previously accrued interest on loans placed on non-accrual status during the period and proceeds from loans on nonaccrual status only to the extent cash payments have been received and applied as interest income and accretion of purchased loan discounts. Yields on tax-exempt securities and loans have been adjusted upward to reflect the effect of income exempt from federal income taxation at the federal statutory tax rate of 35 percent for 2015, 2016 and 2017. Due to the Tax Cuts and Jobs Act of 2017, the federal tax rate will be 21 percent for 2018; as such, the upward adjustment to reflect the effect of income exempt from federal taxation will be lower in 2018.

Provision for Loan Losses The Company manages credit costs by consistently enforcing conservative underwriting and administration procedures and aggressively pursuing collection efforts with debtors experiencing financial difficulties. The provision for loan losses reflects Management's assessment of credit risk in the loan portfolio during each of the periods presented. The Company recorded a reversal of the provision for loan losses of $1.9 million in 2017 and $3.2 million in 2016. The Company provided no provision for loan losses in 2015. Classified loans declined $10.5 million (which included nonperforming loans of $5.9 million) in 2017. The Company’s net loan losses decreased from $1.7 million in 2015 to $617 thousand in 2016 and $1.0 million in 2017; these developments were reflected in Management’s evaluation of credit quality, the level of the provision for loan losses, and the adequacy of the allowance for loan losses at December 31, 2017. At December 31, 2017, the Company had $7.8 million in residential real estate secured loans which are indemnified from loss by the FDIC up to eighty percent of principal; the indemnification expires February 6, 2019. For further information regarding credit risk, the FDIC loss-sharing agreements, net credit losses and the allowance for loan losses, see the “Loan Portfolio Credit Risk” and “Allowance for Loan Losses” sections of this Report.

Merchant processing services fees increased $2.0 million due to successful sales efforts and higher transaction volumes. ATM processing fees and debit card fees increased $199 thousand and $131 thousand, respectively, primarily due to increased transaction volumes. Trust fees increased $189 thousand due to successful sales efforts. Offsetting the increase were service charges on deposits which decreased $1.2 million due to declines in fees charged on overdrawn and insufficient funds accounts (down $1.0 million) and lower fees on analyzed accounts (down $220 thousand). In 2016, noninterest income decreased $1.3 million or 2.7% compared with 2015. Service charges on deposits decreased $1.4 million due to declines in fees charged on overdrawn and insufficient funds accounts (down $1.1 million) and lower fees on analyzed accounts (down $393 thousand). The decrease was partially offset by increased debit card fees of $206 thousand as a result of increased transaction volumes. Noninterest Expense Components of Noninterest Expense Salaries and related benefits Occupancy and equipment Outsourced data processing services Loss contingency Amortization of identifiable intangibles Professional fees Courier service Impairment of tax credit investments Other noninterest expense Total Noninterest Expense 2015 2017 For the Years Ended December 31, 2016 (In thousands) $51,507 19,017 8,505 3 3,504 3,980 1,952 - 13,284 $101,752 $51,519 19,430 9,035 5,542 3,077 2,161 1,732 625 10,171 $103,292 $52,192 19,394 8,441 - 3,856 2,490 2,329 - 16,598 $105,300 In 2017, noninterest expense increased $1.5 million compared with 2016. The 2017 noninterest expense included a $5.5 million loss contingency and a $625 thousand impairment of low income housing limited partnership investments due to enactment of the Tax Cuts and Jobs Act of 2017. The loss contingency represents the Company’s estimated refunds to customers of revenue recognized in prior years. Outsourced data processing services expense increased $530 thousand primarily due to additional processing services. Expenses for occupancy and equipment increased $413 thousand due to technology upgrades. Other noninterest expense decreased $3.1 million primarily due to decreases in correspondent bank service charges and insurance premiums. Professional fees decreased $1.8 million due to lower legal fees associated with nonperforming assets. Amortization of intangibles decreased $427 thousand as assets are amortized on a declining balance method. In 2016, noninterest expense decreased $3.5 million or 3.4% compared with 2015. Salaries and related benefits decreased $685 thousand primarily due to employee attrition, offset in part by higher expenses for stock based compensation. Occupancy and 27 - 27 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K equipment expense decreased $377 thousand in 2016 compared with 2015 mostly due to branch closures and a lease expiration related to a non-branch building, partially offset by higher depreciation costs for technology. Courier expense decreased $377 thousand primarily due to logistical changes and switching to new vendors. Amortization of identifiable intangibles decreased $352 thousand as assets are amortized on a declining balance method. Other operating expense decreased $3.3 million primarily due to lower expenses for correspondent service charges, insurance premiums, operating losses on limited partnership investments and higher net gains on foreclosed properties. Professional fees increased $1.5 million due to higher legal fees associated with loan administration and collection activities. Provision for Income Tax The income tax provision (FTE) was $49.3 million in 2017 compared with $34.2 million in 2016 and $32.1 million in 2015. The 2017 income tax provision (FTE) included a $12.3 million charge to re-measure the Company’s net deferred tax asset triggered by enactment of the Tax Cuts and Jobs Act of 2017. Effective January 1, 2017, the Company adopted ASU 2016-09 which has the potential to create volatility in the book tax provision at the time nonqualified stock options are exercised or expire. During 2017, 509 thousand shares were issued due to the exercise of nonqualified stock options resulting in a tax deduction exceeding related share based compensation by $1.7 million. The 2017 income tax provision was $698 thousand lower than it would have been under accounting standards prior to the adoption of ASU 2016-09. The 2017 effective tax rate (FTE) was 49.6% compared with 36.8% in 2016 and 35.3% in 2015. The effective tax rates without FTE adjustments were 42.6% for 2017, 26.4% for 2016 and 23.4% for 2015. The effective tax rates for 2017 were higher than the effective tax rates for 2016 due to the 2017 $12.3 million charge to re-measure the Company’s net deferred tax asset, higher pre-tax income, and declining tax preference items. The effective tax rates for 2016 were higher than the effective tax rates for 2015 due to higher pre-tax income and declining tax preference items. Interest income earned on municipal securities and loans which are exempt from federal income taxes and the tax credits earned from investments in limited partnerships have each declined in 2017 and 2016. Investment Securities Portfolio The Company maintains an investment securities portfolio consisting of securities issued by U.S. Government sponsored entities, agency and non-agency mortgage backed securities, state and political subdivisions, corporations, and other securities. Management has increased the investment securities portfolio in response to deposit growth and loan volume declines. The carrying value of the Company’s investment securities portfolio was $3.4 billion as of December 31, 2017 and $3.2 billion as of December 31, 2016. Management continually evaluates the Company’s investment securities portfolio in response to established asset/liability management objectives, changing market conditions that could affect profitability, liquidity, and the level of interest rate risk to which the Company is exposed. These evaluations may cause Management to change the level of funds the Company deploys into investment securities and change the composition of the Company’s investment securities portfolio. In 2016 Management reduced securities of U.S. Government sponsored entities to reduce call optionality and increased agency residential MBS to develop more reliable cash flows. In 2017 corporate securities increased in order to improve yields without extending the duration of the bond portfolio. As of December 31, 2017, substantially all of the Company’s investment securities continue to be investment grade rated by one or more major rating agencies. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset-backed securities. The Company’s procedures for evaluating investments in securities are in accordance with guidance issued by the Board of Governors of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating Agencies” (SR 12-15) and other regulatory guidance. There have been no significant differences in our internal analyses compared with the ratings assigned by the third party credit rating agencies.

Management has evaluated investment security exposures within the counties receiving disaster designations. The Company’s exposures are limited to municipal and corporate bond investment securities from issuers within Texas, Florida and Georgia counties. The Company holds municipal bonds of $19 million issued by 17 municipalities within Texas counties, $8 million issued by eight municipalities within Florida counties and $6 million issued by four municipalities within Georgia counties.

In addition, the Company holds one $12.0 million (market value) corporate bond maturing in 2021 issued by a regulated utility in a Texas county which can recapture capital expenditures through rates charged customers; the market value of this corporate bond at December 31, 2017 was 119.0% of its par value, which reflects the bond’s 9.15% coupon rate. Based on currently available information, Management does not expect any of the bonds affected by the hurricanes to become impaired; Management will continue to monitor the value of these bonds for impairment.

Loan Portfolio The Company originates loans with the intent to hold such assets until principal is repaid. Management follows written loan underwriting policies and procedures which are approved by the Bank’s Board of Directors. Loans are underwritten following approved underwriting standards and lending authorities within a formalized organizational structure. The Board of Directors also approves independent real estate appraisers to be used in obtaining estimated values for real property serving as loan collateral. Prevailing economic trends and conditions are also taken into consideration in loan underwriting practices. All loan applications must be for clearly defined legitimate purposes with a determinable primary source of repayment, and as appropriate, secondary sources of repayment. All loans are supported by appropriate documentation such as current financial statements, tax returns, credit reports, collateral information, guarantor asset verification, title reports, appraisals, and other relevant documentation. Commercial loans represent term loans used to acquire durable business assets or revolving lines of credit used to finance working capital. Underwriting practices evaluate each borrower’s cash flow as the principal source of loan repayment. Commercial loans are generally secured by the borrower’s business assets as a secondary source of repayment. Commercial loans are evaluated for credit-worthiness based on prior loan performance and borrower financial information including cash flow, borrower net worth and aggregate debt. Commercial real estate loans represent term loans used to acquire or refinance real estate to be operated by the borrower in a commercial capacity. Underwriting practices evaluate each borrower’s global cash flow as the principal source of loan repayment, independent appraisal of value of the property, and other relevant factors. Commercial real estate loans are generally secured by a first lien on the property as a secondary source of repayment. Real estate construction loans represent the financing of real estate development. Loan principal disbursements are controlled through the use of project budgets, and disbursements are approved based on construction progress, which is validated by project site inspections. A first lien on the real estate serves as collateral to secure the loan. Residential real estate loans generally represent first lien mortgages used by the borrower to purchase or refinance a principal residence. For interest-rate risk purposes, the Company offers only fully-amortizing, adjustable-rate mortgages. In underwriting first lien mortgages, the Company evaluates each borrower’s ability to repay the loan, an independent appraisal of the value of the property, and other relevant factors. The Company does not offer riskier mortgage products, such as non-amortizing “interest- only” mortgages and “negative amortization” mortgages. For loans secured by real estate, the Bank requires title insurance to insure the status of its lien and each borrower is obligated to insure the real estate collateral, naming the Company as loss payee, in an amount sufficient to repay the principal amount outstanding in the event of a property casualty loss. Consumer installment and other loans are predominantly comprised of indirect automobile loans with underwriting based on credit history and scores, personal income, debt service capacity, and collateral values. For management purposes, the Company segregates its loan portfolio into two segments. Loans originated by the Company following its loan underwriting policies and procedures are separated from loans purchased from the FDIC. Loan volumes have declined due to payoffs and problem loan workout activities, particularly with purchased loans, and reduced volumes of loan 33 - 33 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K originations. The Company did not take an aggressive posture relative to loan portfolio growth during the post-recession period of historically low interest rates. Management increased investment securities as loan volumes declined.

Such commitments can be either secured or unsecured and are typically in the form of revolving lines of credit for seasonal working capital needs. Occasionally, such commitments are in the form of letters of credit to facilitate the customers’ particular business transactions. Commitment fees are generally charged for commitments and letters of credit. Commitments on lines of credit and letters of credit typically mature within one year. For further information, see the accompanying notes to the consolidated financial statements. Loan Portfolio Credit Risk The Company extends loans to commercial and consumer customers which expose the Company to the risk borrowers will default, causing loan losses. The Company’s lending activities are exposed to various qualitative risks. All loan segments are exposed to risks inherent in the economy and market conditions. Significant risk characteristics related to the commercial loan segment include the borrowers’ business performance and financial condition, and the value of collateral for secured loans. Significant risk characteristics related to the commercial real estate segment include the borrowers’ business performance and the value of properties collateralizing the loans. Significant risk characteristics related to the construction loan segment include the borrowers’ performance in successfully developing the real estate into the intended purpose and the value of the property collateralizing the loans. Significant risk characteristics related to the residential real estate segment include the borrowers’ financial wherewithal to service the mortgages and the value of the property collateralizing the loans. Significant risk characteristics related to the consumer loan segment include the financial condition of the borrowers and the value of collateral securing the loans. 34 - 34 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 The preparation of the financial statements requires Management to estimate the amount of losses inherent in the loan portfolio and establish an allowance for credit losses. The allowance for credit losses is maintained by assessing or reversing a provision for loan losses through the Company’s earnings. In estimating credit losses, Management must exercise judgment in evaluating information deemed relevant, such as financial information regarding individual borrowers, overall credit loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing economic conditions and other information. The amount of ultimate losses on the loan portfolio can vary from the estimated amounts. Management follows a systematic methodology to estimate loss potential in an effort to reduce the differences between estimated and actual losses. The Company closely monitors the markets in which it conducts its lending operations and follows a strategy to control exposure to loans with high credit risk. The Bank’s organization structure separates the functions of business development and loan underwriting; Management believes this segregation of duties avoids inherent conflicts of combining business development and loan approval functions. In measuring and managing credit risk, the Company adheres to the following practices.  The Bank maintains a Loan Review Department which reports directly to the audit committee of the Board of Directors. The Loan Review Department performs independent evaluations of loans to challenge the credit risk grades assigned by Management using grading standards employed by bank regulatory agencies. Those loans judged to carry higher risk attributes are referred to as “classified loans.” Classified loans receive elevated Management attention to maximize collection.  The Bank maintains two loan administration offices whose sole responsibility is to manage and collect classified loans. Classified loans with higher levels of credit risk are further designated as “nonaccrual loans.” Management places classified loans on nonaccrual status when full collection of contractual interest and principal payments is in doubt. Uncollected interest previously accrued on loans placed on nonaccrual status is reversed as a charge against interest income. The Company does not accrue interest income on loans following placement on nonaccrual status. Interest payments received on nonaccrual loans are applied to reduce the carrying amount of the loan unless the carrying amount is well secured by loan collateral. “Nonperforming assets” include nonaccrual loans, loans 90 or more days past due and still accruing, and repossessed loan collateral (commonly referred to as “Other Real Estate Owned”). Nonperforming Assets Nonperforming nonaccrual loans Performing nonaccrual loans Total nonaccrual loans Accruing loans 90 or more days past due Total nonperforming loans Other real estate owned Total nonperforming assets 2017 2016 At December 31, 2015 (In thousands) 2014 2013 $1,641 4,285 5,926 531 6,457 1,426 $7,883 $3,956 4,429 8,385 497 8,882 3,095 $11,977 $14,648 350 14,998 295 15,293 9,264 $24,557 $17,494 110 17,604 502 18,106 6,374 $24,480 $19,893 1,409 21,302 410 21,712 13,320 $35,032 Nonperforming assets have declined during 2016 and 2017 due to payoffs, chargeoffs and sale of Other Real Estate Owned. At December 31, 2017, one loan secured by commercial real estate with a balance of $4.3 million was on nonaccrual status. The remaining five nonaccrual loans held at December 31, 2017 had an average carrying value of $328 thousand and the largest carrying value was $1.0 million. Management believes the overall credit quality of the loan portfolio is reasonably stable; however, classified and nonperforming assets could fluctuate from period to period. The performance of any individual loan can be affected by external factors such as the interest rate environment, economic conditions, and collateral values or factors particular to the borrower. No assurance can be given that additional increases in nonaccrual and delinquent loans will not occur in the future. 35 - 35 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K Allowance for Credit Losses The Company’s allowance for loan losses represents Management’s estimate of loan losses inherent in the loan portfolio. In evaluating credit risk for loans, Management measures loss potential of the carrying value of loans. As described above, payments received on nonaccrual loans may be applied against the principal balance of the loans until such time as full collection of the remaining recorded balance is expected. The following table summarizes the allowance for loan losses, chargeoffs and recoveries for the periods indicated: Analysis of the Allowance for Loan Losses Balance, beginning of period Provision for loan losses Loans charged off: Commercial Commercial real estate Construction Residential real estate Consumer and other installment Total chargeoffs Recoveries of loans previously charged off: Commercial Commercial real estate Construction Consumer and other installment Total recoveries Net loan losses Balance, end of period 2017 2016 For the Years Ended December 31, 2015 ($ in thousands) 2014 2013 $25,954 (1,900) (961) - - - (4,957) (5,918) 762 88 1,899 2,124 4,873 (1,045) $23,009 $29,771 (3,200) (2,023) - - - (4,749) (6,772) 4,028 554 - 1,573 6,155 (617) $25,954 $31,485 - (756) (449) (431) - (3,493) (5,129) 1,174 290 45 1,906 3,415 (1,714) $29,771 $31,693 2,800 (2,152) (1,022) - (30) (4,214) (7,418) 2,275 213 53 1,869 4,410 (3,008) $31,485 $30,234 8,000 (4,472) (1,816) (237) (109) (4,097) (10,731) 1,765 273 - 2,152 4,190 (6,541) $31,693 Net loan losses as a percentage of average loans 0.08% 0.04% 0.11% 0.17% 0.33% The Company's allowance for loan losses is maintained at a level considered appropriate to provide for losses that can be estimated based upon specific and general conditions. These include conditions unique to individual borrowers, as well as overall loan loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing economic conditions and other factors. A portion of the allowance is individually allocated to impaired loans whose full collectability of principal is uncertain. Such allocations are determined by Management based on loan-by-loan analyses. The Company evaluates for impairment all loans with outstanding principal balances in excess of $500 thousand which are classified or on nonaccrual status and all “troubled debt restructured” loans. The remainder of the loan portfolio is collectively evaluated for impairment based in part on quantitative analyses of historical loan loss experience of loan portfolio segments to determine standard loss rates for each segment. The loss rate for each loan portfolio segment reflects both the historical loss experience during a look-back period and a loss emergence period. Liquidating purchased consumer installment loans are evaluated separately by applying historical loss rates to forecasted liquidating principal balances to measure losses inherent in this portfolio segment. The loss rates are applied to segmented loan balances to allocate the allowance to the segments of the loan portfolio. The remainder of the allowance is considered to be unallocated. The unallocated allowance is established to provide for probable losses that have been incurred as of the reporting date but not reflected in the allocated allowance. The unallocated allowance addresses additional qualitative factors consistent with Management's analysis of the level of risks inherent in the loan portfolio, which are related to the risks of the Company's general lending activity. Included in the unallocated allowance is the risk of losses that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in loan chargeoff history (external factors). The primary external factor evaluated by the Company and the judgmental amount of unallocated reserve assigned by Management as of December 31, 2017 is economic and business conditions $0.5 million. Also included in the unallocated allowance is the risk of losses attributable to general attributes of the Company's loan portfolio and credit administration (internal factors). The internal factors evaluated by the Company and the judgmental amount of unallocated reserve assigned by Management are: loan review system $1.1 million, adequacy of lending Management and staff $0.5 million and concentrations of credit $1.3 million. 36 - 36 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 The following table presents the allocation of the allowance for loan losses as of December 31 for the years indicated: 2017 2016 At December 31, 2015 2014 2013 Allocation of the Allowance Balance Loans as Percent of Total Loans Allocation of the Allowance Balance Loans as Percent of Total Loans Allocation of the Allowance Balance Loans as Percent of Total Loans Allocation of the Allowance Balance Loans as Percent of Total Loans Allocation of the Allowance Balance Loans as Percent of Total Loans Commercial Commercial real estate Construction Residential real estate Consumer installment and other Unallocated portion Total $7,746 3,849 335 995 6,418 3,666 $23,009 26% 44% 1% 5% 24% - % 100% $8,327 3,330 152 1,330 7,980 4,835 $25,954 26% 40% - % 7% 27% - % 100% ($ in thousands) $9,559 4,212 235 1,801 8,001 5,963 $29,771 25% 42% - % 8% 25% - % 100% $5,460 4,245 654 2,241 9,827 9,058 $31,485 23% 42% 1% 9% 25% - % 100% $4,005 12,223 617 405 4,591 9,852 $31,693 20% 44% 1% 10% 25% - % 100% The 2017 decline in the allowance for loan losses was due to declines in classified loans, delinquent loans, and the overall loan portfolio. The increase in the allocation of the allowance for loan losses to commercial real estate and construction loans is due to increased loan volumes outstanding. The decline in the unallocated portion was due to improved economic conditions within the Company’s geographic markets.

The fundamental objective of the Company's management of assets and liabilities is to maximize its economic value while maintaining adequate liquidity and a conservative level of interest rate risk. Interest Rate Risk Interest rate risk is a significant market risk affecting the Company. Many factors affect the Company’s exposure to interest rates, such as general economic and financial conditions, customer preferences, historical pricing relationships, and re-pricing characteristics of financial instruments. Assets and liabilities may mature or re-price at different times. Assets and liabilities may re-price at the same time but by different amounts. Short-term and long-term market interest rates may change by different amounts. The timing and amount of cash flows of various assets or liabilities may shorten or lengthen as interest rates change. In addition, the changing levels of interest rates may have an impact on loan demand, demand for various deposit products, credit losses, and other elements of earnings such as account analysis fees on commercial deposit accounts and correspondent bank service charges. The Company’s earnings are affected not only by general economic conditions, but also by the monetary and fiscal policies of the United States government and its agencies, particularly the Federal Open Market Committee (the “FOMC”). The monetary policies of the FOMC can influence the overall growth of loans, investment securities, and deposits and the level of interest rates earned on assets and paid for liabilities. The nature and impact of future changes in monetary policies are generally not predictable. Management expects a high level of uncertainty in regard to interest rate levels in the immediate term, and Management’s most likely earnings forecast for the twelve months ending December 31, 2018 assumes market interest rates will gradually rise, with short-term rates rising more than long-term rates. In adjusting the Company's asset/liability position, Management attempts to manage interest rate risk while enhancing the net interest margin and net interest income. At times, depending on expected increases or decreases in general interest rates, the relationship between long and short-term interest rates, market conditions and competitive factors, Management may adjust the Company's interest rate risk position in order to manage its net interest margin and net interest income. The Company's results of operations and net portfolio values remain subject to changes in interest rates and to fluctuations in the difference between long and short-term interest rates. The Company’s asset and liability position was slightly “asset sensitive” at December 31, 2017, depending on the interest rate assumptions applied to the simulation model employed by Management to measure interest rate risk. An “asset sensitive” position results in a slightly larger change in interest income than in interest expense resulting from application of assumed interest rate changes. Simulation estimates depend on, and will change with, the size and mix of the actual and projected balance sheet at the time of each simulation. Management continues to monitor the interest rate environment as well as economic conditions and other factors it deems relevant in managing the Company's exposure to interest rate risk. The Company does not currently engage in trading activities or use derivative instruments to control interest rate risk, even though such activities may be permitted with the approval of the Company's Board of Directors. Market Risk - Equity Markets Equity price risk can affect the Company. As an example, any preferred or common stock holdings, as permitted by banking regulations, can fluctuate in value. Management regularly assesses the extent and duration of any declines in market value, the causes of such declines, the likelihood of a recovery in market value, and its intent to hold securities until a recovery in value occurs. Declines in value of preferred or common stock holdings that are deemed “other than temporary” could result in loss recognition in the Company's income statement. Fluctuations in the Company's common stock price can impact the Company's financial results in several ways. First, the Company has regularly repurchased and retired its common stock; the market price paid to retire the Company's common stock affects the level of the Company's shareholders' equity, cash flows and shares outstanding. Second, the Company's common stock price impacts the number of dilutive equivalent shares used to compute diluted earnings per share. Third, fluctuations in the Company's common stock price can motivate holders of options to purchase Company common stock through the exercise of such options thereby increasing the number of shares outstanding and potentially adding volatility to the book tax provision. 38 - 38 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 Finally, the amount of compensation expense associated with share based compensation fluctuates with changes in and the volatility of the Company's common stock price. Market Risk - Other Market values of loan collateral can directly impact the level of loan chargeoffs and the provision for loan losses. The financial condition and liquidity of debtors issuing bonds and debtors whose mortgages or other obligations are securitized can directly impact the credit quality of the Company’s investment securities portfolio requiring the Company to recognize other than temporary impairment charges. Other types of market risk, such as foreign currency exchange risk, are not significant in the normal course of the Company's business activities. Liquidity and Funding The objective of liquidity management is to manage cash flow and liquidity reserves so that they are adequate to fund the Company's operations and meet obligations and other commitments on a timely basis and at a reasonable cost. The Company achieves this objective through the selection of asset and liability maturity mixes that it believes best meet its needs. The Company's liquidity position is enhanced by its ability to raise additional funds as needed in the wholesale markets. In recent years, the Company's deposit base has provided the majority of the Company's funding requirements. This relatively stable and low-cost source of funds, along with shareholders' equity, provided 98 percent of funding for average total assets in 2017 and in 2016. The stability of the Company’s funding from customer deposits is in part reliant on the confidence clients have in the Company. The Company places a very high priority in maintaining this confidence through conservative credit and capital management practices and by maintaining an appropriate level of liquidity reserves. Liquidity is further provided by assets such as balances held at the Federal Reserve Bank, investment securities, and amortizing loans. The Company's investment securities portfolio provides a substantial secondary liquidity reserve. The Company held $3.4 billion in total investment securities at December 31, 2017. Under certain deposit, borrowing and other arrangements, the Company must hold and pledge investment securities as collateral. At December 31, 2017, such collateral requirements totaled approximately $716 million. Liquidity risk can result from the mismatching of asset and liability cash flows, or from disruptions in the financial markets. The Company performs liquidity stress tests on a periodic basis to evaluate the sustainability of its liquidity. Under the stress testing, the Company assumes outflows of funds increase beyond expected levels. Measurement of such heightened outflows considers the composition of the Company’s deposit base, including any concentration of deposits, non-deposit funding such as short-term borrowings, and unfunded lending commitments. The Company evaluates its stock of highly liquid assets to meet the assumed higher levels of outflows. Highly liquid assets include cash and amounts due from other banks from daily transaction settlements, reduced by branch cash needs and Federal Reserve Bank reserve requirements, and investment securities based on regulatory risk- weighting guidelines. Based on the results of the most recent liquidity stress test, Management is satisfied with the liquidity condition of the Bank and the Company. However, no assurance can be given the Bank or Company will not experience a period of reduced liquidity. Management continually monitors the Company’s cash levels. Loan demand from credit worthy borrowers will be dictated by economic and competitive conditions. The Company aggressively solicits non-interest bearing demand deposits and money market checking deposits, which are the least sensitive to changes in interest rates. The growth of these deposit balances is subject to heightened competition, the success of the Company's sales efforts, delivery of superior customer service, new regulations and market conditions. The Company does not aggressively solicit higher-costing time deposits; as a result, Management anticipates such deposits will decline. Changes in interest rates, most notably rising interest rates, could impact deposit volumes. Depending on economic conditions, interest rate levels, liquidity management and a variety of other conditions, deposit growth may be used to fund loans or purchase investment securities. However, due to possible volatility in economic conditions, competition and political uncertainty, loan demand and levels of customer deposits are not certain. Shareholder dividends are expected to continue subject to the Board's discretion and continuing evaluation of capital levels, earnings, asset quality and other factors. Westamerica Bancorporation ("Parent Company") is a separate entity apart from Westamerica Bank (“Bank”) and must provide for its own liquidity. In addition to its operating expenses, the Parent Company is responsible for the payment of dividends declared for its shareholders, and interest and principal on any outstanding debt. The Parent Company currently has no debt. Substantially all of the Parent Company's revenues are obtained from subsidiary dividends and service fees. 39 - 39 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K The Bank’s dividends paid to the Parent Company, proceeds from the exercise of stock options, and Parent Company cash balances provided adequate cash for the Parent Company to pay shareholder dividends of $41 million in 2017, $40 million in 2016 and $39 million in 2015, and retire common stock in the amount of $314 thousand in 2017, $6 million in 2016 and $15 million in 2015. Payment of dividends to the Parent Company by the Bank is limited under California and Federal laws. The Company believes these regulatory dividend restrictions will not have an impact on the Parent Company's ability to meet its ongoing cash obligations. Contractual Obligations The following table sets forth the known contractual obligations, except deposits, short-term borrowing arrangements and post- retirement benefit plans, of the Company: Within One Year Over One to Three Years At December 31, 2017 Over Three to Five Years (In thousands) After Five Years Operating Lease Obligations Purchase Obligations Total $6,481 8,138 $14,619 $8,025 16,652 $24,677 $2,194 8,518 $10,712 $825 - $825 Total $17,525 33,308 $50,833 Operating lease obligations have not been reduced by minimum sublease rentals of $2 million due in the future under noncancelable subleases. Operating lease obligations may be retired prior to the contractual maturity as discussed in the notes to the consolidated financial statements. The purchase obligation consists of the Company’s minimum liabilities under contracts with third-party automation services providers. Capital Resources The Company has historically generated high levels of earnings, which provide a means of accumulating capital. The Company's net income as a percentage of average shareholders' equity (“return on equity” or “ROE”) has been 8.4% in 2017, 10.9% in 2016 and 11.3% in 2015. The Company also raises capital as employees exercise stock options. Capital raised through the exercise of stock options was $25 million in 2017, $24 million in 2016 and $5 million in 2015. The Company paid common dividends totaling $41 million in 2017, $40 million in 2016 and $39 million in 2015, which represent dividends per common share of $1.57, $1.56 and $1.53, respectively. The Company's earnings have historically exceeded dividends paid to shareholders. The amount of earnings in excess of dividends provides the Company resources to finance growth and maintain appropriate levels of shareholders' equity. In the absence of profitable growth opportunities, the Company has repurchased and retired its common stock as another means to return earnings to shareholders. The Company repurchased and retired 6 thousand shares valued at $314 thousand in 2017, 137 thousand shares valued at $6 million in 2016 and 344 thousand shares valued at $15 million in 2015. The Company's primary capital resource is shareholders' equity, which was $590 million at December 31, 2017 compared with $561 million at December 31, 2016. The Company's ratio of equity to total assets was 10.71% at December 31, 2017 and 10.46% at December 31, 2016. The Company performs capital stress tests on a periodic basis to evaluate the sustainability of its capital. Under the stress testing, the Company assumes various scenarios such as deteriorating economic and operating conditions, unanticipated asset devaluations, and significant operational lapses. The Company measures the impact of these scenarios on its earnings and capital. Based on the results of the most recent stress tests, Management is satisfied with the capital condition of the Bank and the Company. However, no assurance can be given the Bank or Company will not experience a period of reduced earnings or a reduction in capital from unanticipated events and circumstances. 40 - 40 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 Capital to Risk-Adjusted Assets On July 2, 2013, the Federal Reserve Board approved a final rule that implements changes to the regulatory capital framework for all banking organizations. The rule’s provisions which most affected the regulatory capital requirements of the Company and the Bank: Introduced a new “Common Equity Tier 1” capital measurement,   Established higher minimum levels of capital,  Introduced a “capital conservation buffer,”  Increased the risk-weighting of certain assets, and  Established limits on the amount of deferred tax assets with any excess treated as a deduction from Tier 1 capital. Under the final rule, a banking organization that is not subject to the “advanced approaches rule” may make a one-time election not to include most elements of Accumulated Other Comprehensive Income, including net-of-tax unrealized gains and losses on available for sale investment securities, in regulatory capital. Neither the Company nor the Bank is subject to the “advanced approaches rule” and both made the election not to include most elements of Accumulated Other Comprehensive Income in regulatory capital. Banking organizations that are not subject to the “advanced approaches rule” began complying with the final rule on January 1, 2015; on such date, the Company and the Bank became subject to the revised definitions of regulatory capital, the new minimum regulatory capital ratios, and various regulatory capital adjustments and deductions according to transition provisions and timelines. All banking organizations began calculating standardized total risk-weighted assets on January 1, 2015. The transition period for the capital conservation buffer for all banking organizations began on January 1, 2016 and will end January 1, 2019. Any bank subject to the rule which is unable to maintain its “capital conservation buffer” will be restricted in the payment of discretionary executive compensation and shareholder distributions, such as dividends and share repurchases. The final rule did not supersede provisions of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) requiring federal banking agencies to take prompt corrective action (PCA) to resolve problems of insured depository institutions. The final rule revised the PCA thresholds to incorporate the higher minimum levels of capital, including the “common equity tier 1” ratio. The capital ratios for the Company and the Bank under the new capital framework are presented in the tables below, on the dates indicated. At December 31, 2017 Company Bank Effective January 1, 2017 Effective January 1, 2019 Required for Capital Adequacy Purposes To Be Well-capitalized Under Prompt Corrective Action Regulations (Bank) Common Equity Tier I Capital Tier I Capital Total Capital Leverage Ratio (1) Includes 1.25% capital conservation buffer.

Based on current capital projections, the Company and the Bank expect to maintain regulatory capital levels exceeding the highest effective regulatory standard and pay quarterly dividends to shareholders. No assurance can be given that changes in capital management plans will not occur. Deposit Categories The Company primarily attracts deposits from local businesses and professionals, as well as through retail savings and checking accounts, and, to a more limited extent, certificates of deposit. The following table summarizes the Company’s average daily amount of deposits and the rates paid for the periods indicated: Deposit Distribution and Average Rates Paid 2017 Percentage of Total Deposits Average Balance Rate For the Years Ended December 31, 2016 Percentage of Total Deposits ($ In thousands) Average Balance Rate 2015 Percentage of Total Deposits Average Balance Rate Noninterest-bearing demand Interest bearing: Transaction Savings Time less than $100 thousand Time $100 thousand or more Total (1) $2,095,522 44.4% - % $2,026,939 44.1% - % $1,968,817 44.4% - % 888,116 1,492,725 136,324 109,563 18.8% 31.6% 2.9% 2.3% $4,722,250 100.0% 0.03% 0.02% 0.17% 0.38% 0.07% 862,581 1,428,059 154,022 118,750 18.8% 31.1% 3.4% 2.6% $4,590,351 100.0% 0.03% 0.06% 0.26% 0.43% 0.08% 822,156 1,312,100 172,836 161,710 18.5% 29.6% 3.9% 3.6% $4,437,619 100.0% 0.03% 0.06% 0.33% 0.42% 0.10% (1) The rates for total deposits reflect value of noninterest-bearing deposits. The Company’s strategy includes building the value of its deposit base by building balances of lower-costing deposits and avoiding reliance on higher-costing time deposits. From 2015 to 2017 higher costing time deposits declined from 7% to 5% of total deposits. The Company’s average balances of checking and savings accounts represented 95% of average balances of total deposits in 2017 compared with 94% in 2016 and 93% in 2015. Total time deposits were $232 million and $256 million at December 31, 2017 and 2016, respectively.

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. The Company’s system of internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) 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 (iii) 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. Management performed an assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017 based upon criteria in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, Management determined that the Company’s internal control over financial reporting was effective as of December 31, 2017 based on the criteria in Internal Control - Integrated Framework (2013) issued by COSO. The Company’s independent registered public accounting firm has issued an attestation report on Management’s assessment of the Company’s internal control over financial reporting.

The Bank is subject to competition from both financial and nonfinancial institutions and to the regulations of certain agencies and undergoes periodic examinations by those regulatory authorities. All of the financial service operations are considered by management to be aggregated in one reportable operating segment. The Company has evaluated events and transactions subsequent to the balance sheet date. Based on this evaluation, the Company is not aware of any events or transactions that occurred subsequent to the balance sheet date but prior to filing that would require recognition or disclosure in its consolidated financial statements. Certain amounts in prior periods have been reclassified to conform to the current presentation. Summary of Significant Accounting Policies The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America. The following is a summary of significant policies used in the preparation of the accompanying financial statements. Accounting Estimates. Certain accounting policies underlying the preparation of these financial statements require Management to make estimates and judgments about future economic and market conditions. These estimates and judgments may affect reported amounts of assets and liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. Although the estimates contemplate current conditions and how Management expects them to change in the future, it is reasonably possible that in 2018 actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and financial conditions. Principles of Consolidation. The consolidated financial statements include the accounts of the Company and all the Company’s subsidiaries. Significant intercompany transactions have been eliminated in consolidation. The Company does not maintain or conduct transactions with any unconsolidated special purpose entities. Cash. Cash includes Due From Banks balances which are readily convertible to known amounts of cash and are generally 90 days or less from maturity at the time of initiation, presenting insignificant risk of changes in value due to interest rate changes. Securities. Investment securities consist of debt securities of the U.S. Treasury, government sponsored entities, states, counties, municipalities, corporations, agency and non-agency mortgage-backed securities, asset-backed securities and equity securities. Securities transactions are recorded on a trade date basis. The Company classifies its debt and marketable equity securities in one of three categories: trading, available for sale or held to maturity. Trading securities are bought and held principally for the purpose of selling them in the near term. Trading securities are recorded at fair value with unrealized gains and losses included in earnings. Held to maturity securities are those debt securities which the Company has the ability and intent to hold until maturity. Held to maturity securities are recorded at cost, adjusted for the amortization of premiums or accretion of discounts. Securities not included in trading or held to maturity are classified as available for sale. Available for sale securities are recorded at fair value. Unrealized gains and losses, net of the related tax effect, on available for sale securities are included in accumulated other comprehensive income. The Company utilizes third-party sources to value its investment securities; securities individually valued using quoted prices in active markets are classified as Level 1 assets in the fair value hierarchy, and securities valued using quoted prices in active markets for similar securities (commonly referred to as “matrix” pricing) are classified as Level 2 assets in the fair value hierarchy. The Company validates the reliability of third-party provided values by comparing individual security pricing for securities between more than one third-party source. When third-party information is not available, valuation adjustments are estimated in good faith by Management and classified as Level 3 in the fair value hierarchy. A decline in the market value of any available for sale or held to maturity security below amortized cost that is deemed other than temporary results in a charge to earnings and the establishment of a new cost basis for the security. Unrealized investment securities losses are evaluated at least quarterly to determine whether such declines in value should be considered “other than temporary” and therefore be subject to immediate loss recognition in income. Although these evaluations involve significant judgment, an unrealized loss in the fair value of a debt security is generally deemed to be temporary when the fair value of the 52 - 52 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration in the financial condition of the issuer, and the Company does not intend to sell or be required to sell the securities before recovery of its amortized cost. An unrealized loss in the value of an equity security is generally considered temporary when the fair value of the security declined primarily due to current market conditions and not deterioration in the financial condition of the issuer, the Company expects the fair value of the security to recover in the near term and the Company does not intend to sell or be required to sell the securities before recovery of its cost basis. Other factors that may be considered in determining whether a decline in the value of either a debt or an equity security is “other than temporary” include ratings by recognized rating agencies, actions of commercial banks or other lenders relative to the continued extension of credit facilities to the issuer of the security, the financial condition, capital strength and near-term prospects of the issuer, and recommendations of investment advisors or market analysts. The Company follows the guidance issued by the Board of Governors of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating Agencies” (SR 12-15) and other regulatory guidance when performing investment security pre-purchase analysis or evaluating investment securities for impairment. Credit ratings issued by recognized rating agencies are considered in the Company’s analysis only as a guide to the historical default rate associated with similarly-rated bonds. Purchase premiums are amortized and purchase discounts are accreted over the estimated life of the related investment security as an adjustment to yield using the effective interest method. Unamortized premiums, unaccreted discounts, and early payment premiums are recognized as a component of gain or loss on sale upon disposition of the related security. Interest and dividend income are recognized when earned. Realized gains and losses from the sale of available for sale securities are included in earnings using the specific identification method. Nonmarketable Equity Securities. Nonmarketable equity securities include securities that are not publicly traded, such as Visa Class B common stock, and securities acquired to meet regulatory requirements, such as Federal Reserve Bank stock, which are restricted. These restricted securities are accounted for under the cost method and are included in other assets. The Company reviews those assets accounted for under the cost method at least quarterly for possible declines in value that are considered “other than temporary”. The Company’s review typically includes an analysis of the facts and circumstances of each investment, the expectations for the investment’s cash flows and capital needs, the viability of its business model and any exit strategy. The asset value is reduced when a decline in value is considered to be other than temporary. The Company recognizes the estimated loss in noninterest income. Loans. Loans are stated at the principal amount outstanding, net of unearned discount and unamortized deferred fees and costs. Interest is accrued daily on the outstanding principal balances. Loans which are more than 90 days delinquent with respect to interest or principal, unless they are well secured and in the process of collection, and other loans on which full recovery of principal or interest is in doubt, are placed on nonaccrual status. Interest previously accrued on loans placed on nonaccrual status is charged against interest income. In addition, some loans secured by real estate with temporarily impaired values and commercial loans to borrowers experiencing financial difficulties are placed on nonaccrual status (“performing nonaccrual loans”) even though the borrowers continue to repay the loans as scheduled. When the ability to fully collect nonaccrual loan principal is in doubt, payments received are applied against the principal balance of the loans on a cost-recovery method until such time as full collection of the remaining recorded balance is expected. Any additional interest payments received after that time are recorded as interest income on a cash basis. Performing nonaccrual loans are reinstated to accrual status when improvements in credit quality eliminate the doubt as to the full collectability of both interest and principal. Certain consumer loans or auto receivables are charged off against the allowance for credit losses when they become 120 days past due. The Company evaluates all classified loans and nonaccrual loans with outstanding principal balances in excess of $500 thousand, and all “troubled debt restructured” loans for impairment. The Company recognizes a loan as impaired when, based on current information and events, it is probable that it will be unable to collect both the contractual interest and principal payments as scheduled in the loan agreement. Income recognition on impaired loans conforms to that used on nonaccrual loans. In certain circumstances, the Company might agree to restructured loan terms with borrowers experiencing financial difficulties; such restructured loans are evaluated under ASC 310-40, “Troubled Debt Restructurings by Creditors.” In general, a restructuring constitutes a troubled debt restructuring when the Company, for reasons related to a borrower’s financial difficulties, grants a concession to the borrower it would not otherwise consider. Loans are evaluated on an individual basis. The Company follows its general nonaccrual policy for troubled debt restructurings. Performing troubled debt restructurings are reinstated to accrual status when improvements in credit quality eliminate the doubt as to full collectability of both principal and interest. Nonrefundable fees and certain costs associated with originating or acquiring loans are deferred and amortized as an adjustment to interest income over the contractual loan lives. Upon prepayment, unamortized loan fees, net of costs, are immediately recognized in interest income. Other fees, including those collected upon principal prepayments, are included in interest income 53 - 53 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K when received. Loans held for sale are identified upon origination and are reported at the lower of cost or market value on an aggregate loan basis. Purchased Loans. Purchased loans are recorded at estimated fair value on the date of purchase. Impaired purchased loans are accounted for under FASB ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, when the loans have evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the purchase date may include attributes such as past due and nonaccural status. Generally, purchased loans that meet the Company’s definition for nonaccrual status fall within the scope of FASB ASC 310-30. The difference between contractually required payments at acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result in a reversal of the provision for loan losses to the extent of prior charges, or a reclassification of the difference from nonaccretable to accretable with a positive impact on interest income on a prospective basis. Any excess of expected cash flows over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is a reasonable expectation about the amount and timing of such cash flows. For covered purchased loans with an accretable difference, the corresponding FDIC receivable is amortized over the shorter of the contractual term of the indemnification asset or the remaining life of the loan. Further, the Company elected to analogize to ASC 310-30 and account for all other loans that had a discount due in part to credit not within the scope of ASC 310-30 using the same methodology. Covered Loans. Loans covered under loss-sharing or similar credit protection agreements with the FDIC are reported in loans exclusive of the expected reimbursement cash flows from the FDIC. Covered loans are initially recorded at fair value at the acquisition date. Subsequent decreases in the amount expected to be collected results in a provision for loan losses and a corresponding increase in the estimated FDIC reimbursement, with the estimated net loss impacting earnings. Interest previously accrued on covered loans placed on nonaccrual status is charged against interest income, net of estimated FDIC reimbursements of such accrued interest. The FDIC reimburses the Company up to 80% of 90 days interest on covered loans. Allowance for Credit Losses. The Company extends loans to commercial and consumer customers primarily in Northern and Central California. These lending activities expose the Company to the risk borrowers will default, causing loan losses. The Company’s lending activities are exposed to various qualitative risks. All loan segments are exposed to risks inherent in the economy and market conditions. Significant risk characteristics related to the commercial loan segment include the borrowers’ business performance and financial condition, and the value of collateral for secured loans. Significant risk characteristics related to the commercial real estate segment include the borrowers’ business performance and the value of properties collateralizing the loans. Significant risk characteristics related to the construction loan segment include the borrowers’ performance in successfully developing the real estate into the intended purpose and the value of the property collateralizing the loans. Significant risk characteristics related to the residential real estate segment include the borrowers’ financial wherewithal to service the mortgages and the value of the property collateralizing the loans. Significant risk characteristics related to the consumer loan segment include the financial condition of the borrowers and the value of collateral securing the loans. The preparation of these financial statements requires Management to estimate the amount of probable incurred losses inherent in the loan portfolio and establish an allowance for credit losses. The allowance for credit losses is established by assessing a provision for loan losses against the Company’s earnings. In estimating credit losses, Management must exercise significant judgment in evaluating information deemed relevant, such as financial information regarding individual borrowers, overall credit loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing economic conditions and other information. The amount of ultimate losses on the loan portfolio can vary from the estimated amounts. Management follows a systematic methodology to estimate loss potential in an effort to reduce the differences between estimated and actual losses. The allowance for credit losses is established through provisions for credit losses charged to income. Losses on loans, including impaired loans, are charged to the allowance for loan losses when all or a portion of the recorded amount of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the allowance when realized. The Company’s allowance for credit losses is maintained at a level considered adequate to provide for losses that can be estimated based upon specific and general conditions. These include conditions unique to individual borrowers, as well as overall credit loss experience, the amount of past due, nonperforming and classified loans, recommendations of regulatory authorities, prevailing economic conditions, FDIC loss-sharing or similar credit protection agreements and other factors. A portion of the allowance is specifically allocated to impaired loans whose full collectability is uncertain. Such allocations are determined by Management based on loan- by-loan analyses. The Company evaluates all classified loans and nonaccrual loans with outstanding principal balances in excess of $500 thousand, and all “troubled debt restructured” loans for impairment. A second allocation is based in part on quantitative analyses of historical credit loss experience. The results of this analysis are applied to current loan balances to allocate the reserve to the respective segments of the loan portfolio exclusive of loans individually evaluated for impairment. In addition, consumer 54 - 54 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 installment loans which have similar characteristics and are not usually criticized using regulatory guidelines are analyzed and reserves established based on the historical loss rates and delinquency trends, grouped by the number of days the payments on these loans are delinquent. The remainder of the reserve is considered to be unallocated. The unallocated allowance is established to provide for probable losses that have been incurred as of the reporting date but not reflected in the allocated allowance. It addresses additional qualitative factors consistent with Management’s analysis of the level of risks inherent in the loan portfolio, which are related to the risks of the Company’s general lending activity. Included in the unallocated allowance is the risk of losses that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in past loan charge-off history (external factors). The external factors evaluated by the Company include: economic and business conditions, external competitive issues, and other factors. Also included in the unallocated allowance is the risk of losses that are attributable to general attributes of the Company’s loan portfolio and credit administration (internal factors). The internal factors evaluated by the Company include: loan review system, adequacy of lending Management and staff, loan policies and procedures, problem loan trends, concentrations of credit, and other factors. By their nature, these risks are not readily allocable to any specific segment of the loan portfolio in a statistically meaningful manner. Liability for Off-Balance Sheet Credit Exposures. A liability for off-balance sheet credit exposures is established through expense recognition. Off-balance sheet credit exposures relate to letters of credit and unfunded loan commitments for commercial, construction and consumer loans. Historical credit loss factors for commercial, construction and consumer loans are applied to the amount of these off-balance sheet credit exposures to estimate inherent losses. Other Real Estate Owned. Other real estate owned is comprised of property acquired through foreclosure proceedings, acceptances of deeds-in-lieu of foreclosure and, if applicable, vacated bank properties. Losses recognized at the time of acquiring property in full or partial satisfaction of debt are charged against the allowance for credit losses. Other real estate owned is recorded at the fair value of the collateral, generally based upon an independent property appraisal, less estimated disposition costs. Losses incurred subsequent to acquisition due to any decline in annual independent property appraisals are recognized as noninterest expense. Routine holding costs, such as property taxes, insurance and maintenance, and losses from sales and dispositions, are recognized as noninterest expense. Covered Other Real Estate Owned. Other real estate owned covered under loss-sharing agreements with the FDIC is reported exclusive of expected reimbursement cash flows from the FDIC. Upon transferring covered loan collateral to covered other real estate owned status, the covered loan collateral is recorded at fair value, generally based upon an independent property appraisal, less estimated disposition costs with losses charged against acquisition date fair value discounts; the amount of losses exceeding acquisition date fair value discounts are recognized as noninterest expense inclusive of expected reimbursement cash flows from the FDIC. Subsequent losses incurred due to any decline in annual independent property appraisal valuations are recognized as noninterest expense inclusive of expected reimbursement cash flows from the FDIC. Premises and Equipment. Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed substantially on the straight-line method over the estimated useful life of each type of asset. Estimated useful lives of premises and equipment range from 20 to 50 years and from 3 to 20 years, respectively. Leasehold improvements are amortized over the terms of the lease or their estimated useful life, whichever is shorter. Revenue Recognition. The Company recognizes revenue as it is earned based on contractual terms, as transactions occur, or as services are provided and collectability is reasonably assured. In certain circumstances, noninterest income is reported net of associated expenses that are directly related to variable volume-based sales or revenue sharing arrangements or when the Company acts on an agency basis for others. Life Insurance Cash Surrender Value. The Company has purchased life insurance policies on certain directors and officers as well as acquired such assets as part of the acquisition of other banks. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. These assets are included in other assets on the consolidated balance sheets. Intangible Assets. Intangible assets are comprised of goodwill, core deposit intangibles and other identifiable intangibles acquired in business combinations. Intangible assets with definite useful lives are amortized on an accelerated basis over their respective estimated useful lives not exceeding 15 years. If an event occurs that indicates the carrying amount of an intangible asset may not be recoverable, Management reviews the asset for impairment. Any goodwill and any intangible asset acquired in a purchase business combination determined to have an indefinite useful life is not amortized, but is evaluated for impairment annually. The Company has the option to first assess qualitative factors to determine the likelihood of impairment pursuant to FASB ASU 2011- 08, Testing for Goodwill Impairment. Although the Company has the option to first assess qualitative factors when determining if impairment exists, the Company has opted to perform a quantitative analysis to determine if impairment exists. 55 - 55 - Impairment of Long-Lived Assets. The Company reviews its long-lived and certain intangible assets for impairment whenever events or changes indicate that the carrying amount of an asset may not be recoverable. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Income Taxes. The Company and its subsidiaries file consolidated tax returns. The Company accounts for income taxes in accordance with FASB ASC 740, Income Taxes, resulting in two components of income tax expense: current and deferred. Current income tax expense approximates taxes to be paid or refunded for the current period. The Company determines deferred income taxes using the balance sheet method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and recognizes enacted changes in tax rates and laws in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are recognized subject to Management’s judgment that realization is more likely than not. A tax position that meets the more likely than not recognition threshold is measured to determine the amount of benefit to recognize. The tax position is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon settlement. Interest and penalties are recognized as a component of income tax expense. Stock Options. The Company applies FASB ASC 718 – Compensation – Stock Compensation, to account for stock based awards granted to employees using the fair value method. The Company recognizes compensation expense for restricted performance share grants over the relevant attribution period. Restricted performance share grants have no exercise price, therefore, the intrinsic value is measured using an estimated per share price at the vesting date for each restricted performance share. The estimated per share price is adjusted during the attribution period to reflect actual stock price performance. The Company’s obligation for unvested outstanding restricted performance share grants is classified as a liability until the vesting date due to a cash settlement feature, at which time the issued shares become classified as shareholders’ equity. Extinguishment of Debt. Gains and losses, including fees, incurred in connection with the early extinguishment of debt are charged to current earnings as reductions in noninterest income. Postretirement Benefits. The Company uses an actuarial-based accrual method of accounting for post-retirement benefits. Other. Securities and other property held by the Bank in a fiduciary or agency capacity are not included in the financial statements since such items are not assets of the Company or its subsidiaries. 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K Recently Adopted Accounting Standards In 2017, the Company adopted the following new accounting guidance: FASB Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting, was issued March 30, 2016. The provisions of the new standard changed several aspects of the accounting for share-based payment award transactions, including: (1) Accounting and Cash Flow Classification for Excess Tax Benefits, (2) Forfeitures, and (3) Tax Withholding Requirements and Cash Flow Classification. The Company adopted the ASU provisions effective January 1, 2017, which has the potential to create volatility in the book tax provision at the time nonqualified stock options are exercised or expire. During 2017, 509 thousand shares were issued due to the exercise of nonqualified stock options resulting in a tax deduction exceeding related share based compensation by $1,667 thousand. The 2017 income tax provision was $698 thousand lower than it would have been under accounting standards prior to the adoption of ASU 2016-09. The Company elected to account for forfeitures as they occur. Recently Issued Accounting Standards FASB ASU 2014-09, Revenue (Topic 606): Revenue from Contracts with Customers, was issued May 2014. The ASU specifies a standardized approach for revenue recognition across industries and transactions. The ASU also requires additional disclosures. The scope of the ASU does not include revenue streams covered by other ASU topics; thus, Topic 606 does not apply to revenue related to financial instruments, guarantees and leases, such as the Company’s net interest income. Approximately 73% of our revenue, including all of our net interest income and a portion of our noninterest income, is out of scope of the guidance. The contracts that are in scope of the guidance are primarily related to service charges and fees on deposit accounts, merchant processing fees, trust fees and other service charges, commissions and fees. We have completed analyzing the 56 - 56 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 individual contracts in scope and determined our revenue recognition will not change in any material regard upon adoption of the ASU. The Company adopted the ASU on January 1, 2018. FASB ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities, was issued January 2016. The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most notably, the ASU changes the income statement impact of equity investments held by the Company and the requirement for the Company to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. The Company was required to adopt the ASU provisions on January 1, 2018, and for those equity securities with readily determinable fair values, the Company elected the retrospective transition approach with a cumulative effect adjustment to the balance sheet and for those equity securities that do not have readily determinable fair values, the Company elected the prospective transition approach. The impact of the adoption of this accounting standard on the Company’s consolidated financial statements will be subject to the price volatility of the equity investments, which is immaterial. At December 31, 2017, the Company had $2000 thousand in equity investments with readily determinable fair value. FASB ASU 2016-02, Leases (Topic 842), was issued February 25, 2016. The provisions of the new standard require lessees to recognize most leases on-balance sheet, increasing reported assets and liabilities. Lessor accounting remains substantially similar to current U.S. GAAP. The Company will be required to adopt the ASU provisions January 1, 2019, and plans to elect the modified retrospective transition approach. Management is evaluating the impact that the ASU will have on the Company’s financial statements. As of December 31, 2017, the Company leased 58 of its operating facilities; the remaining minimum lease payments were $17.5 million. The Company does not expect a material change in noninterest expenses upon adoption of the new standard. FASB ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, was issued on June 16, 2016. The ASU significantly changes estimates for credit losses related to financial assets measured at amortized cost and certain other contracts. For estimating credit losses, the FASB is replacing the incurred loss model with the current expected credit loss (CECL) model, which will accelerate recognition of credit losses. Additionally, credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses under the new standard. The Company will also be required to provide additional disclosures related to the financial assets within the scope of the new standard. The Company will be required to adopt the ASU provisions on January 1, 2020. Management is evaluating the impact that the ASU will have on the Company’s consolidated financial statements. The ultimate adjustment to the allowance for loan losses will be accomplished through an offsetting after-tax adjustment to shareholders’ equity. Economic conditions and the composition of the Company’s loan portfolio at the time of adoption will influence the extent of the adopting accounting adjustment. FASB ASU 2017-08, Receivables – Non-Refundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities, was issued March 2017. The ASU will shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The Company will be required to adopt the ASU provisions on January 1, 2019. Management is evaluating the impact the ASU will have on the Company’s financial statements. FASB ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, was issued August 2017. The ASU will expand and refine hedge accounting for both nonfinancial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The ASU also provides for a one-time reclassification of prepayable assets from held-to-maturity (HTM) to available for sale (AFS) regardless of derivative use. The Company will be required to adopt the ASU provisions January 1, 2019. The Company does not currently engage in trading activities or use derivative instruments to control interest rate risk, even though such activities may be permitted with the approval of the Company’s Board of Directors. However, the Company is currently evaluating the prepayable assets in the HTM portfolio to determine if a one-time reclassification of prepayable assets from HTM to the AFS will occur upon implementation. 57 - 57 - Note 2: Investment Securities An analysis of the amortized cost, gross unrealized gains and losses accumulated in other comprehensive income, and fair value of the available for sale investment securities portfolio follows: Investment Securities Available for Sale At December 31, 2017 Gross Gross Unrealized Unrealized Losses Gains (In thousands) Amortized Cost Securities of U.S. Government sponsored entities Agency residential mortgage-backed securities (MBS) Non-agency residential MBS Agency commercial MBS Securities of U.S. Government entities Obligations of states and political subdivisions Corporate securities Other securities Total $122,285 787,679 153 2,244 1,612 182,907 1,123,671 2,000 $2,222,551 $1 522 1 - - 3,796 1,104 - $5,424 ($2,967) (20,495) - (25) (22) (1,482) (9,277) (200) ($34,468) Fair Value $119,319 767,706 154 2,219 1,590 185,221 1,115,498 1,800 $2,193,507 An analysis of the amortized cost, gross unrecognized gains and losses, and fair value of the held to maturity investment securities portfolio follows: Agency residential MBS Non-agency residential MBS Agency commercial MBS Obligations of states and political subdivisions Total Investment Securities Held to Maturity At December 31, 2017 Gross Gross Unrecognized Unrecognized Losses Gains (In thousands) $606 70 - 7,736 $8,412 ($9,850) - (66) (2,018) ($11,934) Amortized Cost $545,883 4,462 9,041 599,478 $1,158,864 Fair Value $536,639 4,532 8,975 605,196 $1,155,342 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K [The remainder of this page intentionally left blank] 58 - 58 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 An analysis of the amortized cost, gross unrealized gains and losses accumulated in other comprehensive income, and fair value of the available for sale investment securities portfolio follows: Investment Securities Available for Sale At December 31, 2016 Gross Gross Unrealized Unrealized Losses Gains (In thousands) Amortized Cost $141,599 711,623 272 2,041 182,230 696 749 866,835 2,034 $1,908,079 $35 921 - - 5,107 - 10,120 1,690 621 $18,494 ($2,974) (21,045) (1) (16) (3,926) (1) - (7,668) (184) ($35,815) Fair Value $138,660 691,499 271 2,025 183,411 695 10,869 860,857 2,471 $1,890,758 Securities of U.S. Government sponsored entities Agency residential MBS Non-agency residential MBS Securities of U.S. Government entities Obligations of states and political subdivisions Asset-backed securities FHLMC(1) and FNMA(2) stock Corporate securities Other securities Total (1) Federal Home Loan Mortgage Corporation (2) Federal National Mortgage Association An analysis of the amortized cost, gross unrecognized gains and losses, and fair value of the held to maturity investment securities portfolio follows: Securities of U.S. Government sponsored entities Agency residential MBS Non-agency residential MBS Agency commercial MBS Obligations of states and political subdivisions Total Investment Securities Held to Maturity At December 31, 2016 Gross Gross Unrecognized Unrecognized Losses Gains (In thousands) $1 1,122 76 11 6,031 $7,241 $- (8,602) - (143) (4,067) ($12,812) Amortized Cost $581 668,235 5,370 9,332 662,794 $1,346,312 Fair Value $582 660,755 5,446 9,200 664,758 $1,340,741 During the quarter ending December 31, 2017, the Company sold its shares of FHLMC and FNMA stock.

In addition, such factors as prepayments and interest rates may affect the yield on the carrying value of mortgage-related securities. At December 31, 2017 and December 31, 2016, the Company had no high-risk collateralized mortgage obligations as defined by regulatory guidelines.

The Company evaluates securities on a quarterly basis including changes in security ratings issued by rating agencies, changes in the financial condition of the issuer, and, for mortgage-backed and asset- backed securities, delinquency and loss information with respect to the underlying collateral, changes in the levels of subordination for the Company’s particular position within the repayment structure and remaining credit enhancement as compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a major rating agency. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities. The Company does not intend to sell any investments and has concluded that it is more likely than not that it will not be required to sell the investments prior to recovery of the amortized cost basis. Therefore, the Company does not consider these investments to be other-than-temporarily impaired as of December 31, 2017. The fair values of the investment securities could decline in the future if the general economy deteriorates, inflation increases, credit ratings decline, the issuer’s financial condition deteriorates, or the liquidity for securities declines. As a result, other than temporary impairments may occur in the future. As of December 31, 2017, $715,774 thousand of investment securities were pledged to secure public deposits and short-term borrowed funds. As of December 31, 2016, $768,845 thousand of investment securities were pledged to secure public deposits and short-term borrowed funds. 61 - 61 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K An analysis of gross unrealized losses of investment securities available for sale follows: Investment Securities Available for Sale At December 31, 2016 No. of Investment Positions Less than 12 months Fair Value Unrealized Losses No. of Investment Positions 12 months or longer Unrealized Losses Fair Value ($ in thousands) No. of Investment Positions Total Fair Value Unrealized Losses 8 21 2 2 43 - 53 - 129 $117,227 524,269 ($2,974) (16,494) 246 1,253 (1) (9) 57,989 (3,905) - 385,175 - $1,086,159 - (6,551) - ($29,934) - 28 - 1 3 1 27 1 61 $- 122,901 $- (4,551) - 772 - (7) 1,117 (21) 695 96,145 1,816 $223,446 (1) (1,117) (184) ($5,881) 8 49 2 3 46 1 80 1 190 $117,227 647,170 ($2,974) (21,045) 246 2,025 (1) (16) 59,106 (3,926) 695 481,320 1,816 $1,309,605 (1) (7,668) (184) ($35,815) Securities of U.S. Government sponsored entities Agency residential MBS Non-agency residential MBS Securities of U.S. Government entities Obligations of states and political subdivisions Asset-backed securities Corporate securities Other securities Total An analysis of gross unrecognized losses of investment securities held to maturity follows: Investment Securities Held to Maturity At December 31, 2016 No. of Investment Positions Less than 12 months Fair Value Unrecognized Losses No. of Investment Positions Agency residential MBS Agency commercial MBS Obligations of states and political subdivisions Total 66 - 295 361 $569,876 - ($8,285) - 272,496 $842,372 (3,710) ($11,995) 3 1 12 16 12 months or longer Fair Value ($ in thousands) $10,480 7,214 13,126 $30,820 Unrecognized Losses ($317) (143) (357) ($817) No. of Investment Positions Total Fair Value Unrecognized Losses 69 1 307 377 $580,356 7,214 ($8,602) (143) 285,622 $873,192 (4,067) ($12,812) The following table provides information about the amount of interest income earned on investment securities which is fully taxable and which is exempt from regular federal income tax: 2017 For the Years Ended December 31, 2016 (In thousands) 2015 Taxable Tax-exempt from regular federal income tax Total interest income from investment securities $51,445 20,651 $72,096 $42,718 22,194 $64,912 $34,472 23,616 $58,088 [The remainder of this page intentionally left blank] 62 - 62 - K - 0 1 M R O F I N O T A R O P R O C N A B A C I R E M A T S E W 7 1 0 2 Note 3: Loans and Allowance for Credit Losses A summary of the major categories of loans outstanding is shown in the following tables at the dates indicated.

Given the scale of these borrowers, corporate credit rating agencies do not evaluate the borrowers’ financial condition. The Bank maintains a Loan Review Department which reports directly to Audit Committee of the Board of Directors. The Loan Review Department performs independent evaluations of loans and validates management assigned credit risk grades on evaluated loans using grading standards employed by bank regulatory agencies. Loans judged to carry lower-risk attributes are assigned a “pass” grade, with a minimal likelihood of loss. Loans judged to carry higher-risk attributes are referred to as “classified loans,” and are further disaggregated, with increasing expectations for loss recognition, as “substandard,” “doubtful,” and “loss.” Loan Review Department evaluations occur every calendar quarter. If the Bank becomes aware of deterioration in a borrower’s performance or financial condition between Loan Review Department examinations, assigned risk grades are re-evaluated promptly. Credit risk grades assigned by management and validated by the Loan Review Department are subject to review by the Bank’s regulatory authorities during regulatory examinations.

The market value as of December 31, 2017 was $59.55 as reported by the NASDAQ Global Select Market: Options Outstanding Options Exercisable At December 31, 2017 Range of Exercise Price Number Outstanding Aggregate Intrinsic Value $40 - 45 45 - 50 50 - 55 55 - 60 $40 - 60 (In thousands) 400 22 310 298 1,030 $6,798 305 2,588 725 $10,416 Weighted Average Remaining Contractual Life (Years) 7.5 4.1 1.9 8.3 6.0 For the Year Ended December 31, 2017 Weighted Average Exercise Price $43 46 51 57 49 At December 31, 2017 Number Exercisable Aggregate Intrinsic Value (In thousands) 105 22 310 32 469 $1,751 305 2,588 94 $4,738 Weighted Average Remaining Contractual Life (Years) 6.9 4.1 1.9 2.1 3.1 For the Year Ended December 31, 2017 Weighted Average Exercise Price $43 46 51 57 49 [The remainder of this page intentionally left blank] 71 - 71 - The Company applies the Roll-Geske option pricing model (Modified Roll) to determine grant date fair value of stock option grants. This model modifies the Black-Scholes Model to take into account dividends and American options. During the twelve months ended December 31, 2017, 2016 and 2015, the Company granted 266 thousand, 325 thousand and 343 thousand stock options, respectively. The following weighted average assumptions were used in the option pricing to value stock options granted in the periods indicated: Expected volatility (1) Expected life in years (2) Risk-free interest rate (3) Expected dividend yield Fair value per award For the Years Ended December 31, 2017 2016 2015 20% 4.8 1.97% 3.28% $8.27 22% 4.8 1.41% 4.49% $5.97 20% 4.9 1.36% 3.64% $5.46 (1) Measured using daily price changes of Company’s stock over respective expected term of the option and the implied volatility derived from the market prices of the Company’s stock and traded options. (2) The number of years that the Company estimates that the options will be outstanding prior to exercise. (3) The risk-free rate over the expected life based on the US Treasury yield curve in effect at the time of the grant. Employee stock option grants are being expensed by the Company over the grants’ three year vesting period. The Company issues new shares upon the exercise of options. The number of shares authorized to be issued for options at December 31, 2017 is 930 thousand. A summary of option activity during the year ended December 31, 2017 is presented below: 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K Weighted Average Exercise Price $47.36 57.18 48.29 N/A 49.44 49.45 Shares (In thousands) 1,273 266 (509) - 1,030 469 Weighted Average Remaining Contractual Term (Years) 6.0 3.1 Outstanding at January 1, 2017 Granted Exercised Forfeited or expired Outstanding at December 31, 2017 Exercisable at December 31, 2017 A summary of the Company’s nonvested option activity during the year ended December 31, 2017 is presented below: Nonvested at January 1, 2017 Granted Vested Forfeited Nonvested at December 31, 2017 Weighted Average Grant Date Fair Value $5.80 8.27 5.78 N/A $6.98 Shares (In thousands) 553 266 (258) - 561 The weighted average estimated grant date fair value for options granted under the Company’s stock option plan during the twelve months ended December 31, 2017, 2016 and 2015 was $8.27, $5.97 and $5.46 per share, respectively. The total remaining unrecognized compensation cost related to nonvested awards as of December 31, 2017 is $2,012 thousand and the weighted average period over which the cost is expected to be recognized is 0.9 years. The total intrinsic value of options exercised during the twelve months ended December 31, 2017, 2016 and 2015 was $4,642 thousand, $3,242 thousand and $504 thousand, respectively. The total fair value of Restricted Performance Shares (“RPSs”) that vested during the twelve months ended December 31, 2017, 2016 and 2015 was $708 thousand, $753 thousand and $741 thousand, respectively.

The Company adopted the ASU provisions effective January 1, 2017, which has the potential to create volatility in the book tax provision at the time nonqualified stock options are exercised or expire. During the twelve months of 2017, 509 thousand shares were issued due to the exercise of nonqualified stock options resulting in a tax deduction exceeding related share based compensation by $1,667 thousand. The 2017 income tax provision was $698 thousand lower than would have been under accounting standards prior to the adoption of ASU 2016-09. The increase in tax benefits recognized for the tax deductions from the exercise of options totaled $394 thousand for the twelve months ended December 31, 2016. The decrease in tax benefits recognized for the tax deductions from the exercise of options totaled $1,284 thousand for the twelve months ended December 31, 2015. A summary of the status of the Company’s restricted performance shares as of December 31, 2017 and 2016 and changes during the twelve months ended on those dates, follows: Outstanding at January 1, Granted Issued upon vesting Forfeited Outstanding at December 31, 2017 2016 (In thousands) 48 14 (13) - 49 45 18 (15) - 48 As of December 31, 2017 and 2016, the restricted performance shares had a weighted-average contractual life of 1.2 years and 1.1 years, respectively. The compensation cost that was charged against income for the Company’s restricted performance shares granted was $827 thousand, $1,228 thousand and $535 thousand for the twelve months ended December 31, 2017, 2016 and 2015, respectively. There were no stock appreciation rights or incentive stock options granted in the twelve months ended December 31, 2017 and 2016. On February 13, 2009, the Company issued a warrant to purchase 246,640 shares of the Company’s common stock at an exercise price of $50.92 per share. The warrants may be exercised in a manner wherein the Company withholds shares of common stock issuable upon exercise of the warrant equal in value to the aggregate exercise price, in which case the warrant holder would not deliver cash for the aggregate exercise price and the Company would issue a number of shares equal to the intrinsic value on the exercise date. The warrants remain outstanding at December 31, 2017. The Company repurchases and retires its common stock in accordance with Board of Directors approved share repurchase programs. At December 31, 2017, approximately 1,750 thousand shares remained available to repurchase under such plans. Shareholders have authorized two additional classes of stock of one million shares each, to be denominated “Class B Common Stock” and “Preferred Stock,” respectively, in addition to the 150 million shares of common stock presently authorized. At December 31, 2017, no shares of Class B Common Stock or Preferred Stock were outstanding. Note 9: Regulatory Capital Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel III rules, the Company must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer is being phased in from 0.0% for 2015 to 2.50% by 2019. The capital conservation buffer for 2017 was 1.25% and 0.625% for 2016. The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2017, the Company and Bank met all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At year-end 2017 and 2016, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt 73 - 73 - corrective action. There are no conditions or events since that notification that management believes have changed the institution’s category. The capital ratios for the Company and the Bank under the new capital framework as of the dates indicated are presented in the table below.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Amounts for the current year are based upon estimates and assumptions as of the date of these financial statements and could vary significantly from amounts shown on the tax returns as filed. The components of the net deferred tax asset are as follows: Deferred tax asset Allowance for credit losses State franchise taxes AMT carryforward Securities available for sale Deferred compensation Real estate owned Purchased assets and assumed liabilities Post-retirement benefits Employee benefit accruals VISA Class B shares Limited partnership investments Impaired capital assets Accrued liabilities Premises and equipment Other Total deferred tax asset Deferred tax liability Net deferred loan fees Intangible assets Other Total deferred tax liability Net deferred tax asset At December 31, 2017 2016 (In thousands) $7,349 1,871 1,752 8,586 5,279 553 1,111 526 2,066 96 57 3,056 1,609 299 520 34,730 281 1,247 90 1,618 $33,112 $11,801 2,679 - 7,283 8,043 756 3,026 903 3,399 137 86 18,465 967 577 724 58,846 346 2,955 128 3,429 $55,417 Based on Management’s judgment, a valuation allowance is not needed to reduce the gross deferred tax asset because it is more likely than not that the gross deferred tax asset will be realized through recoverable taxes or future taxable income.

Note 11: Fair Value Measurements The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale investment securities are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as other real estate owned, impaired loans, certain loans held for investment, investment securities held to maturity, and other assets. These nonrecurring fair value adjustments typically involve the lower-of-cost or fair-value accounting of individual assets. In accordance with the Fair Value Measurement and Disclosure topic of the Codification, the Company bases its fair values on the price that would be received to sell an asset or paid to transfer a liability in the principal market or most advantageous market for an asset or liability in an orderly transaction between market participants on the measurement date under current market conditions. A fair value measurement reflects all of the assumptions that market participants would use in pricing the asset or liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or use of an asset, and the risk of nonperformance. The Company groups its assets and liabilities measured at fair value into a three-level hierarchy, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. When the valuation assumptions used to measure the fair value of the asset or liability are categorized within different levels of the fair value hierarchy, the asset or liability is categorized in its entirety within the lowest level of the hierarchy. These levels are: Level 1 – Valuation is based upon quoted prices for identical instruments traded in active exchange markets, such as the New York Stock Exchange. Level 1 includes U.S. Treasury and equity securities, which are traded by dealers or brokers in active markets. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. Level 2 includes federal agency securities, mortgage-backed securities, corporate securities, asset- backed securities, and municipal bonds. Level 3 – Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. The Company relies on independent vendor pricing services to measure fair value for investment securities available for sale and investment securities held to maturity. The Company employs three pricing services. To validate the pricing of these vendors, the Company compares vendors’ pricing for each of the securities for consistency; significant pricing differences, if any, are evaluated using all available independent quotes with the quote closely affecting the market generally used as the fair value estimate. In addition, the Company conducts “other than temporary impairment (OTTI)” analysis on a quarterly basis; securities selected for OTTI analysis include all securities at a market price below 95 percent of par value. As with any valuation technique used to estimate fair value, changes in underlying assumptions used could significantly affect the results of current and future values. Accordingly, these fair value estimates may not be realized in an actual sale of the securities. The Company regularly reviews the valuation techniques and assumptions used by its vendors and determines which valuation techniques are utilized based on observable market inputs for the type of securities being measured. The Company uses the information to determine the placement in the fair value hierarchy as level 1, 2 or 3. When the Company changes its valuation assumptions for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions or other factors, or reevaluates the valuation techniques and assumptions used by its vendors, it may need to transfer those assets or liabilities to another level in the hierarchy based on the new information. The Company recognizes these transfers at the end of 77 - 77 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K the reporting period that the transfers occur. For the years ended December 31, 2017 and 2016, there were no transfers into or out of levels 1, 2 or 3.

These adjustments to fair value usually result from application of lower of cost or fair value accounting of individual assets. For assets measured at fair value on a nonrecurring basis that were recorded in the balance sheet at December 31, 2017 and December 31, 2016, the following tables provide the level of valuation assumptions used to determine each adjustment and the carrying value of the related assets at period end.

Level 3 includes other real estate owned that has been measured at fair value upon transfer to foreclosed assets and impaired loans collateralized by real property and other business asset collateral where a specific reserve has been established or a chargeoff has been recorded. Losses on other real estate owned represent losses recognized in earnings during the period subsequent to its initial classification as foreclosed assets. The unobservable inputs and qualitative information about the unobservable inputs are not presented as the inputs were not developed by the Company. Disclosures about Fair Value of Financial Instruments The following section describes the valuation methodologies used by the Company for estimating fair value of financial instruments not recorded at fair value in the balance sheet. Cash and Due from Banks Cash and due from banks represent U.S. dollar denominated coin and currency, deposits at the Federal Reserve Bank and correspondent banks, and amounts being settled with other banks to complete the processing of customers’ daily transactions. Collectively, the Federal Reserve Bank and financial institutions operate in a market in which cash and due from banks transactions are processed continuously in significant daily volumes honoring the face value of the U.S. dollar. Investment Securities Held to Maturity The fair values of investment securities were estimated using quoted prices as described above for Level 2 valuation. Loans Loans were separated into two groups for valuation. Variable rate loans, except for those described below, which reprice frequently with changes in market rates were valued using historical cost. Fixed rate loans and variable rate loans that have reached their minimum contractual interest rates were valued by discounting the future cash flows expected to be received from the loans using current interest rates charged on loans with similar characteristics. Additionally, the allowance for loan losses of $23,009 thousand at December 31, 2017 and $25,954 thousand at December 31, 2016 was applied against the estimated fair values to recognize estimated future defaults of contractual cash flows. 79 - 79 - Deposit Liabilities Deposits with no stated maturity such as checking accounts, savings accounts and money market accounts can be readily converted to cash or used to settle transactions at face value through the broad financial system operated by the Federal Reserve Bank and financial institutions. The fair value of deposits with no stated maturity is equal to the amount payable on demand. The fair values of time deposits were estimated by discounting estimated future contractual cash flows using current market rates for financial instruments with similar characteristics. Short-Term Borrowed Funds The carrying amount of securities sold under agreement to repurchase and other short-term borrowed funds approximate fair value due to the relatively short period of time between their origination and their expected realization. The tables below are a summary of fair value estimates for financial instruments and the level of the fair value hierarchy within which the fair value measurements are categorized, excluding financial instruments recorded at fair value on a recurring basis. The values assigned do not necessarily represent amounts which ultimately may be realized for assets or paid to settle liabilities. In addition, these values do not give effect to adjustments to fair value which may occur when financial instruments are sold or settled in larger quantities.

Substantially all the leases contain renewal options and provisions for rental increases, principally for cost of living index. The Company also leases certain pieces of equipment. Minimum future rental payments under noncancelable operating leases as of December 31, 2017 are as follows: 2018 2019 2020 2021 2022 Thereafter Total minimum lease payments Minimum future rental payments (In thousands) $6,481 4,882 3,143 1,462 732 825 $17,525 The total minimum future rental payments have not been reduced by minimum sublease rentals of $2,088 thousand due in the future under noncancelable subleases. Total rentals for premises were $6,695 thousand in 2017, $6,823 thousand in 2016 and $8,359 thousand in 2015. Total sublease rentals were $406 thousand in 2017, $435 thousand in 2016 and $1,721 thousand in 2015. Total rentals for premises, net of sublease income, included in noninterest expense were $6,289 thousand in 2017, $6,388 thousand in 2016 and $6,638 thousand in 2015. Note 13: Commitments and Contingent Liabilities Loan commitments are agreements to lend to a customer provided there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future funding requirements. Loan commitments are subject to the Company’s normal credit policies and collateral requirements. Unfunded loan commitments were $272,646 thousand and $304,508 thousand at December 31, 2017 and 2016, respectively. Standby letters of credit commit the Company to make payments on behalf of customers when certain specified future events occur. Standby letters of credit are primarily issued to support customers’ short-term financing requirements and must meet the Company’s normal credit policies and collateral requirements. Financial and performance standby letters of credit outstanding totaled $19,263 thousand and $21,732 thousand at December 31, 2017 and 2016, respectively. The Company had no commitments outstanding for commercial and similar letters of credit at December 31, 2017 and 2016. The Company had a reserve for unfunded commitments of $2,308 thousand at December 31, 2017 and $2,408 thousand at December 31, 2016, included in other liabilities. Due to the nature of its business, the Company is subject to various threatened or filed legal cases. Based on the advice of legal counsel, the Company does not expect such cases will have a material, adverse effect on its financial position or results of operations. Legal liabilities are accrued when obligations become probable and the amount can be reasonably estimated. The Company has determined that it will be obligated to provide refunds of revenue recognized in prior years to some customers. The Company estimates the probable amount of these obligations will be $5,542 thousand and has accrued a liability for such amount; the estimated liability is subject to revision. The October 2017 California wildfires have disrupted operations in the Company's geographic footprint mainly due to temporary power outages, unhealthy air quality, and evacuations affecting some branches and an operations center. The Company maintains secondary power generation capability at its principal operations center. The Company maintains, and regularly tests, disaster recovery plans and protocols to be prepared for disasters such as these wildfires. The Company has not experienced a casualty loss as of the date of this report, but does carry customary casualty insurance to protect against such risk. Management has performed an initial evaluation of loss exposure caused by the wildfires within the Company's loan portfolio and investment portfolio; Management has not identified any increased risk of loss, however, continuing Management evaluations and further wildfire developments could result in identification of losses which are not currently apparent. 81 - 81 - Note 14: Retirement Benefit Plans The Company sponsors a qualified defined contribution Deferred Profit-Sharing Plan covering substantially all of its salaried employees with one or more years of service. The costs charged to noninterest expense related to discretionary Company contributions to the Deferred Profit-Sharing Plan were $944 thousand in 2017, $1,000 thousand in 2016 and $734 thousand in 2015. The Company also sponsors a qualified defined contribution Tax Deferred Savings/Retirement Plan (ESOP) covering salaried employees who become eligible to participate upon completion of a 90-day introductory period. The Tax Deferred Savings/ Retirement Plan (ESOP) allows employees to defer, on a pretax or after-tax basis, a portion of their salaries as contributions to this Plan. Participants may invest in several funds, including one fund that invests primarily in Westamerica Bancorporation common stock. The Company funds contributions to match participating employees’ contributions, subject to certain limits. The matching contributions charged to compensation expense were $1,098 thousand in 2017, $1,075 thousand in 2016 and $1,147 thousand in 2015. The Company offers a continuation of group insurance coverage to eligible employees electing early retirement, for the period from the date of retirement until age 65. For eligible employees the Company pays a portion of these early retirees’ group insurance premiums. The Company also reimburses a portion of Medicare Part B premiums for all qualifying retirees over age 65 and, if eligible, their spouses. Eligibility for post-retirement medical benefits is based on age and years of service, and restricted to employees hired prior to February 1, 2006 who elect early retirement prior to January 1, 2019. The Company uses an actuarial- based accrual method of accounting for post-retirement benefits. The Company used a December 31 measurement date for determining post-retirement medical benefit calculations. The following tables set forth the net periodic post-retirement benefit cost and the change in the benefit obligation for the years ended December 31 and the funded status of the post-retirement benefit plan as of December 31: 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K Net Periodic Benefit Cost Service benefit Interest cost Amortization of unrecognized transition obligation Net periodic (benefit) cost 2017 At December 31, 2016 (In thousands) ($153) 108 61 $16 ($311) 95 61 ($155) 2015 ($202) 106 61 ($35) Other Changes in Benefit Obligations Recognized in Other Comprehensive Income Amortization of unrecognized transition obligation, net of tax Total recognized in net periodic (benefit) cost and accumulated other comprehensive income (34) ($189) (36) ($20) (36) ($71) The transition obligation for this post-retirement benefit plan became fully amortized during the twelve months ended December, 2017.

The Company reserves the right to terminate or alter post-employment health benefits. Post-retirement medical benefits are currently fixed amounts without provision for future increases; as a result, the assumed annual average rate of inflation used to measure the expected cost of benefits covered by this program is zero percent for 2017 and beyond. Assumed benefit inflation rates are not applicable for this program. 2018 2019 2020 2021 2022 Years 2023-2027 Estimated future benefit payments (In thousands) $138 131 124 118 112 482 [The remainder of this page intentionally left blank] 83 - 83 - 2 0 1 7 W E S T A M E R I C A B A N C O R P O R A T O N I F O R M 1 0 - K Note 15: Related Party Transactions Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries of the Company in the ordinary course of business. In Management’s opinion, with the exception of the Company’s Employee Loan Program, all outstanding loans and commitments included in such transactions were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons, did not involve more than a normal risk of collectability, and did not present other favorable features. As part of the Employee Loan Program, all employees, including executive officers, are eligible to receive mortgage loans at one percent below Westamerica Bank’s prevailing interest rate at the time of loan origination. In Management’s opinion, all loans to executive officers under the Employee Loan Program are made by Westamerica Bank in compliance with the applicable restrictions of Section 22(h) of the Federal Reserve Act. The table below reflects information concerning loans to certain directors and executive officers and/or family members during 2017 and 2016: Balance at January 1, Originations Principal reductions Balance at December 31, Percent of total loans outstanding.

The amount that can be paid in any calendar year, without prior approval from regulatory agencies, cannot exceed the net profits (as defined) for the preceding three calendar years less dividends paid. Under this regulation, the Bank obtained approval for dividends paid to the Company during 2017. The Company consistently has paid quarterly dividends to its shareholders since its formation in 1972. The Bank is required to maintain reserves with the Federal Reserve Bank equal to a percentage of its reservable deposits. The Bank’s daily average on deposit at the Federal Reserve Bank was $458,186 thousand in 2017 and $365,880 thousand in 2016, which amounts exceed the Bank’s required reserves.

We also have audited the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three- year period ended December 31, 2017 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO. Basis for Opinions The Company’s management is responsible for these 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. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. 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. Definition and Limitations of Internal Control Over Financial Reporting 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. 89 - 89 - 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. /s/ Crowe Horwath LLP Crowe Horwath LLP We have served as the Company's auditor since 2015.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES The Company’s principal executive officer and principal financial officer have evaluated the effectiveness of the Company’s “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, as of December 31, 2017. Based upon their evaluation, the principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures are effective to ensure that material information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported as and when required and that such information is communicated to the Company’s management, including the principal executive officer and the principal financial officer, to allow for timely decisions regarding required disclosures. The evaluation did not identify any change in the Company’s internal control over financial reporting that occurred during the quarter ended December 31, 2017 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. Management’s Report on Internal Control Over Financial Reporting and the attestation Report of Independent Registered Public Accounting Firm are found on pages 46 and 89, respectively. ITEM 9B.
