PROXY STATEMENT 
March 15, 2024 
___________ 

GENERAL 

The Westamerica Board of Directors is soliciting proxies to be used at the 2024 Annual Meeting of Shareholders of 
Westamerica Bancorporation (the “Company”), which will be held at 10:00 a.m. Pacific Time, Thursday, April 25, 
2024, or at any adjournment or postponement of the  Annual Meeting (collectively, the  “Annual Meeting”). The 
Board of Directors is soliciting proxies to give all shareholders 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 15, 2024, 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 March 6, 2024, 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 March 6, 2024;  
 
  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.  

the Notice of Internet Availability of Proxy Materials; 

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 proxies 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 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 31, 2024. Management is not aware of any other business to come before the Annual 

1 

2024     WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
Meeting, and as of the date of this proxy statement, no shareholder has submitted to management any proposal to be 
acted upon at the Annual Meeting. 

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  the  record  date,  March  6,  2024,  26,677,701  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 if 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 eight 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.  

Vote Required; Effect of Abstentions and Broker Non-Votes. The shares of a shareholder whose proxy 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 provided by your broker or 
other custodian. If you wish to vote the shares you own beneficially at the meeting in person, 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 proposal. Brokers and custodians cannot vote uninstructed shares 
on your behalf in the election of directors or the advisory votes on executive compensation. For your vote to be 
counted on these matters, you must submit your voting instruction form to your broker or custodian.  

The following table summarizes the votes required for passage of each proposal and the effect of abstentions and 
uninstructed shares held by brokers:

Abstentions and nonvotes will have no effect on the outcome of the Proposal 1.Votes in favor of Proposals 2 and 3 
must also constitute a majority of the required quorum for the meeting. Therefore, if votes in favor are less than a 
majority of the required quorum, abstentions and non-votes would have the effect of a vote against the proposal. 

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. 

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. 

Voting Deadlines. Shareholders voting by telephone or internet must vote by 12:01 a.m. Central Time, on April 
25, 2024 to ensure that their vote  is  counted. If you are a participant  in  the Westamerica  Bancorporation Tax 
Deferred Savings/Retirement Plan (ESOP), however, your vote must be received by 11:59 p.m. Central Time, on 
April 15, 2024.   

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 at a later time by 
telephone or on the internet prior to 12:01 a.m. Central Time, on April 25, 2024 (prior to 11:59 p.m. Central Time, 
on April 15, 2024 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. If you are a beneficial holder and 
own your shares in street name, contact your broker, bank or other holder of record to discontinue householding 
and receive your own separate copy of the Notice in future years. If you are a registered holder and own your 
shares through Computershare Investor Services, contact Computershare toll-free at 877-588-4258 or in writing 
directed to Computershare Investor Services, 150 Royall  Street, Suite  101,  Canton, MA  02021 to discontinue

to discontinue duplicate mailings of the Notice.

Availability of Proxy Materials or paper copies of proxy materials, this Proxy Statement and the 2023 Annual 
Report  are  available  on  the  Company’s  website  at:  www.westamerica.com.  If  you  hold  your  Westamerica 
Bancorporation common stock in street name through a broker, a bank or other nominee, you may have the option 
of securing your Proxy Statement and Annual Report via the internet. If you vote this year’s proxy electronically,

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 A. Belew, E.J. Bowler, M. Camsey, M. M. Chiesa, M. Hassid, E.B. Sylvester, 
and I. Wondeh are “independent” Directors as defined in NASDAQ rules. Mr. Payne is not independent because he 
is an officer of the Company and the Bank. 

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,  and  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 named executive officers have an average tenure of 32 years and do 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  seven  of  our  eight  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 the Compliance 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  serves  at  least  one  year  from  the  date  of 
appointment 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.

2024     WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
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  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 2023. 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 2023 Annual  Meeting of  Shareholders  attended the 
meeting.

Audit Committee. The Board of Directors has determined that all members of the Audit Committee are independent, 
as that term is defined by applicable rules of NASDAQ for Audit Committee purposes. The Board has also designated 
Ms. Hassid is an  “Audit Committee financial expert” as defined by the rules of the SEC and has determined that she 
is “financially sophisticated” under NASDAQ rules. In concluding that Ms. Hassid is the Audit Committee financial 
expert, the Board determined that she possess: 

  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;  

  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  (or  persons) 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. 

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 2024 and attached as Exhibit A to this Proxy Statement. 

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. 

The  Compensation  Committee  administers  Westamerica  Bancorporation’s  equity  incentive  plan,  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 2024 and is attached as Exhibit A to the Proxy Statement for the 2023 

11

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. 

Nominating Committee. The Board of Directors has determined that all members of the Nominating Committee 
are independent, as defined in NASDAQ rules.   

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 considers each existing Board 
member’s contributions. The Committee also considers recommendations of shareholders. 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 by the Board of Directors in January 
2024 and attached as Exhibit A to the Proxy Statement for the 2022 Annual Meeting of Shareholders. 

While the Board does not have a formal diversity policy, it broadly defines diversity to encompass a 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  nonprofit  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. 

Compliance Committee.  The Committee provides oversight of the Company’s Compliance Management System 
to ensure compliance with consumer protection laws and regulations. 

Board  Diversity.  The  table  below  provides  certain  highlights  of  the  composition  of  our  board  members  and 
nominees. Each of the categories listed in the below table has the meaning as it is used in Nasdaq Rule 5605(f):

Code  of  Ethics.  The  Company  has  adopted  a  Code  of  Ethics  (as  defined  in  Item  406  of  Regulation  S-K  of  the 
Securities Act of 1933) that is applicable to its senior financial officers including its chief executive officer, chief 
financial officer, and principal accounting officer. 

Compensation Discussion and Analysis  
The  executive  compensation  practices  described below  have  been  followed  consistently  for  thirty  years.  At  each 
Annual Meeting of Shareholders since 2010, a majority of our shareholders approved an advisory proposal on the 
Company’s executive compensation. Last year 88 percent of the shares voting on this proposal voted to support our 
Corporation’s executive compensation strategy. 

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: 

–  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. The Company’s 2019 Westamerica Omnibus Plan includes a clawback provision with 
similar terms. In October 2023, the clawback policy was revised to comply with new NASDAQ listing standards. 

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 and services offered by the 
Company, adherence to internal controls, management of the credit risk of the Company’s loan and bond portfolios, 
management of liquidity to meet depository customer needs, 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 any acquired companies, operational efficiencies, and capital management practices. 

Restricted performance shares (“RPS”) are restricted stock unit awards that vest upon the achievement of performance 
objectives established by the Compensation Committee. Historically, the Company has granted RPS awards to its 
executives  with  a  three-year  vesting  period  and  vesting  conditions  based  on  performance  factors  including  the 
Company’s three year cumulative diluted earnings per share (EPS), three year average of annual return on average 
total assets (ROA); three year average of annual return on average shareholders’ equity relative to industry average 
ROE (ROE differential); non-performing assets to total assets (NPA); and the efficiency ratio over three years. 

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 

16 

2024   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
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. 

Equity Compensation Plans. Long-term stock grants may only be awarded under shareholder approved stock-based 
incentive compensation plans (the “equity incentive plans”).   

In 2019, the Company’s shareholders approved the 2019 Westamerica Omnibus Plan (the “2019 Plan”). The 2019 
Plan authorizes the grant of up to 1,235,898 shares (plus shares that become available if awards under prior plans 
expire  unexercised  or  are  cancelled,  forfeited  or  terminated  before  being  exercised).    In  addition,  the  2019  Plan 
authorizes the issuance of shares under an award  granted  in the assumption of,  or in substitution for, outstanding 
awards previously granted by another business entity acquired by the Company. Any additional authorization of shares 
available for issuance must be approved by shareholders.  The 2019 Plan expires on April 25, 2029, after which 
shareholder approval is again required to extend the term or approve a new equity incentive plan. 

The 2019 Plan replaced the Company’s 2012 Amended and Restated Stock Option Plan of 1995 (the “2012 Amended 
Plan”).  The Company may no longer grant any awards under the 2012 Amended Plan, though awards previously 
issued under such plan continue to be outstanding, subject to the terms of the applicable awards agreements.   The 
2012 Amended Plan established governing terms and conditions for all stock grants awarded from the effective date 
of the plan through the effective date of the 2019 Plan. 

The 2019 Plan allows the following 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. 

Share Appreciation Rights (“SAR”) provide the holder a cash payment equal to the difference between the fair market 
value of the Westamerica Bancorporation 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 income at the time 
the SAR is settled and the Company receives a corporate tax deduction in the same amount. 

17 

2024     WESTAMERICA BANCORPORATION PROXY 
  
 
 
 
 
 
 
 
Restricted Shares and Restricted Stock Units.   The Compensation Committee determines the vesting schedule and 
performance goals, if any, applicable to the grant of restricted shares and Restricted Stock Units.  Restricted Stock Units 
are awards that may be settled in Westamerica Bancorporation common stock or cash, subject to vesting.  As described 
above, the Company has historically granted Restricted Stock Units as RPS awards that settle in shares of Westamerica 
Bancorporation common stock, 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 equity incentive plans. 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 March 6, 
2024, the Company had no ISO or SAR awards outstanding. 

Determination of Exercise Price. The equity incentive plans require the exercise price of each NQSO, ISO or SAR 
to be no less than one hundred percent (100%) of the fair market value of Westamerica Bancorporation common stock 
on the date of grant. The equity incentive plans do 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  equity  incentive  plans.  The  Compensation  Committee  reports  to  the  Board  the  terms  and 
conditions of  awards  granted under these plans.  In carrying  out  this responsibility,  the  Compensation  Committee 
designs such awards as long-term incentives. The terms and conditions of currently outstanding awards under the 
Company’s several equity incentive plans 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 shares underlying RPS awards until 
vesting occurs and shares awarded become outstanding on a dividend record date.  

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 with responsibilities including oversight of the organization and external strategic initiatives. Mr. Payne 

18 

2024   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
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 34 of this Proxy Statement 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 awards 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 awards 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:

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  2023 
performance were as follows:

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 2023 corporate  performance  goals related  to 
current year “profitability” included return on average equity, return on average 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 (classified loans and other real estate 
owned, non-performing loans and other real estate owned, and net loan losses to average loans) and service quality 
measures (service quality of support departments and branches). The “control” measures include annual non-interest 
expense to annual revenues (efficiency ratio), the level of annual 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.  

At  the  beginning  of  the  year,  the  Compensation  Committee’s  expectations  for  the  2023  operating  environment 
included uncertain economic growth, employment conditions and monetary policy, sustainability of fiscal stimulus 
influences over deposit volumes, and evolution of interest rate levels. The Committee reserved the ability to exercise 
a certain degree of judgment in adjusting target goals based on the ultimate operating environment. 

The Compensation Committee determined the 2023 operating environment was generally characterized as follows: 

 

 
 
 
 
 
 

the  monetary policies of the  Federal Open Market Committee  (FOMC)  remained restrictive,  with an 
elevated federal funds rate influencing depositor yield expectations; 
an inverted Treasury yield curve, which historically signals a likely recession; 
disinflation caused the core rate of inflation to decline toward the FOMC target inflation rate; 
employment conditions remained solid, as defined by the rate of wage increases and low unemployment; 
the Federal Reserve reduced its holdings of bonds, reducing liquidity in the marketplace; 
the banking industry experienced declining core deposit volumes; and 
office  vacancies  remained  elevated  following  the  pandemic,  pressuring  office  commercial  real  estate 
valuations. 

The Compensation Committee considered Management’s response to the current operating environment including: 

  maintaining floating-rate assets which expanded the Company’s net interest income; 
 

implementing proactive communications with depositors to negotiate deposit yields and manage toward a 
low funding costs;  

consistently applying conservative credit risk practices in the loan and bond portfolios; 
adjusting risk-based loan pricing to higher market yields to support long-term financial results; 

  managing toward and maintaining a service-oriented depositor base; 
 
 
  maintaining a prudent liquidity position; 
  management of human resources throughout the organization during a period of tight labor conditions; 
  maintaining relatively low operating costs; and 
 

prudent management of capital enabling the Company to continue providing increasing annual dividends 
per share to shareholders, and positioning the Company for growth opportunities. 

The Compensation Committee exercised judgement by making adjustments to actual results to take into account the 
impact of the operating environment. Adjusted actual results against “target” performance goals were: 

Profitability Goals: 
Return on average shareholders’ equity 
Return on average assets 
Diluted earnings per share

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 114% 
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: 

  managing the Company to achieve 2023 corporate performance goals approved by the Board of Directors, 

including return on equity, return on assets, earnings per share and operating expenses;

Based on individual performance against these goals, the Committee exercised its discretion and assigned Mr. Payne 
a composite corporate and individual performance level of 103%. 

In addition to routine on-going divisional responsibilities, Mr. Thorson managed the Finance and Treasury Divisions 
toward functional goals, which included:

capital levels, and interest rate risk; 

  management of the bond portfolio including credit risk, liquidity, and risks derived from possible movements 

in interest rates;

  manage the Trust Department toward achieving fee goals and prudent investment portfolio management 

practices; and 

  satisfactory regulatory examinations, external audits, and internal audits. 

Based on the Finance and Treasury Divisions’ results, the Committee determined divisional performance to be 129%.

  provide training, mentoring and development to targeted personnel; 
 
  capital management for the Company and subsidiary bank. 

investor relations activities; and 

Based  on  individual  performance  against  these  goals,  the  Committee  determined  Mr.  Thorson’s  individual 
performance to be 150%. As a result, Mr. Thorson’s composite corporate, divisional and individual performance level 
was 125%. 

In addition to routine on-going divisional responsibilities, Mr. Donohoe managed the Operations & Systems Division 
toward functional goals, which included: 

  meet divisional service quality standards; 
  manage divisional operating costs to budgeted levels; 
  completion of projects to control and lower operating expenses; 
  completion of projects to increase noninterest income; 
  satisfactory internal and external audit results; and

In addition to daily management responsibilities, Mr. Donohoe’s individual goals included: 

  providing guidance and management of key divisional regulatory compliance initiatives; 
  staff development; and 
  negotiation of key vendor contracts. 

Based  on  individual  performance  against  these  goals,  the  Committee  determined  Mr.  Donohoe’s  individual 
performance to be 138%. As a result, Mr. Donohoe’s composite corporate, divisional and individual performance 
level was 119%. 

In addition to routine on-going divisional responsibilities, Mr. Rizzardi managed the Credit Division toward functional 
goals, which included: 

  meet loan portfolio credit quality objectives; 
  manage to consistent underwriting standards; 
  satisfactory internal and external audits;

The NQSO grants have an exercise price equal to the fair market value of Westamerica Bancorporation common stock 
on the grant date, vest over a three-year period beginning one year from the date of grant and expire on the tenth 
anniversary of the grant date.  

RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved 
over the three-year period. In January 2024, the Compensation Committee evaluated whether the three-year corporate 
performance objectives were met for RPS awards granted in January 2021. The performance objectives for the RPS 
granted in January 2021 included: 

  3 year cumulative diluted earnings per share (EPS); 
  3 year average of annual return on average total assets (ROA); 
  3 year  average  of  annual  return  on  average  subsidiary  Bank  shareholders’  equity  relative  to  industry 

average ROE (ROE differential); 

  end of period non-performing assets (NPA); and 
  efficiency ratio over 3 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.

With four of the goals achieving the “outstanding” performance, the Compensation Committee determined the RPS 
shares awarded in 2021 vested upon achievement of the 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  401(k) 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. 

24 

2024   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  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 “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 exceeds the equivalent of one times annual salary. Messrs. Payne, Thorson, Donohoe, Rizzardi and Baker 
are eligible for one year’s salary under the plan. 

Internal  Revenue  Code.  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 as of November 2, 2017. 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 and 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, 2023.

(4) The amounts include interest paid on deferred  cash compensation to the extent the interest  exceeds 120% of the long-term  Applicable 
Federal Rates with compounding. The Company has no defined benefit pension plan. Mr. Payne has a pension agreement, which is discussed 
under “Pension Benefits for Fiscal Year 2023.” 
(5)  Each  of the above-named  executive officers  received  less  than $10,000  of  aggregate perquisites  and personal  benefits,  except  for Mr. 
Donohoe who received a car allowance of $12,500. All other compensation includes Company contributions to defined contribution plans 
(ESOP and Deferred Profit Sharing), and amounts added to taxable wages using IRS tables for the cost of providing group term life insurance 
coverage that is more than the cost of $50,000 of coverage. It also includes the dollar value of the benefit to Mr. Payne for the portion of the 
premium payable by the Company with respect to a split dollar life insurance policy (projected on an actuarial basis), and a bonus paid to Mr. 
Payne in the amount of his portion of the split dollar life insurance premium. 
(6) Mr. Leavitt resigned from Westamerica, March of 2023

The executive compensation actually paid differs from the compensation provided in the Summary Compensation 
Table due solely to changes in the value of RPSs and NQSOs between the grant date and the end of each fiscal year 
or vesting date. The change in the value of the NQSOs and RPSs is based on TSR excluding dividends as dividends 
are not paid on NQSOs or RPSs prior to vesting. 

As described in the Compensation Discussion and Analysis, the financial performance measures used to determine 
executive compensation levels include return on average equity, return on average assets, diluted earnings per share, 
levels of non-performing assets, and the efficiency ratio (operating expenses as a percentage of total revenues).  

Financial Performance Measures

- Return on Average Equity

- Return on Average Assets

- Diluted Earnings Per Share

- Levels of Non-Performing Assets

- Efficiency Ratio (Operating Expenses as a Percentage of Total Revenues)

Return on Equity

Pay Ratio Disclosure 
SEC rules require annual disclosure of the ratio of the Company’s median employee’s annual total compensation 
to the total annual compensation of the principal executive officer (“PEO”). The Company’s PEO is Mr. Payne. 

Median Employee total annual compensation 
Mr. Payne total annual compensation 
Ratio of PEO to Median Employee Compensation 

$45,627 
758,701 
16.63:1.0 

In determining the median employee total annual compensation, the Company prepared a census of all employees 
as of December 31, 2023, except the PEO, with compensation annualized for those employees hired in 2023. 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.

•  The performance and vesting period is three years;  
•  Multiple three-year performance goals are established by the Compensation Committee for each grant;  
•  The Compensation Committee may revise the goals upon significant events;  
•  Accelerated vesting occurs upon a “change in control” and 
•  No dividends are paid or accrued prior to settlement or deferral delivery of shares which takes place approximately two months after vesting; 
(2) Includes NQSO grants with an exercise price of not less than 100% of fair market value as of the date of grant.  
The material terms of the NQSO’s listed in the table are as follows:   
•  Options vest ratably over three years beginning one year from date of grant;  
•  Options expire 10 years following grant date; 
•  Exercise price is 100% of fair market value as defined in the 2019 Omnibus Plan;  
•  Dividends are not paid on unexercised options;  
•  Vesting ceases upon termination of employment, whatever the reason, except if vesting is accelerated as described below; 
•  Vested options may be exercised within 90 days of termination of employment and within one year upon death or disability; and  
•  Accelerated vesting occurs upon a “change in control”   
(3) The amounts shown for NQSOs and RPS awards represent the aggregate grant date fair market value.

David L. Payne

Non-Qualified Pension Agreement

$2,633,705

$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 2001, 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 5.02%.  The obligation is an unfunded general obligation 
of the Company.

Under  the  Westamerica  Bancorporation  and  Subsidiaries  Deferred  Compensation  Plan  (the  “Deferred 
Compensation Plan”), Directors and Officers may defer up to 100% of their compensation, salary and/or non-

34 

2024   WESTAMERICA BANCORPORATION PROXY 
 
 
                    
 
 
 
 
 
 
 
 
 
 
equity incentive compensation (cash bonus) into a non-qualified, unfunded deferred compensation program. The 
interest rate credited during 2023 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 
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 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.  Under  the  2019  Plan,  a  change  in  control  occurs  when  (i)  a  person  or  entity  becomes  the 
beneficial owner of more than 50% of voting power of the Company; (ii) there is an unapproved change in the majority 
membership of the Board of Directors; (iii) a merger of the Company or any of its subsidiaries is completed, other 
than (A) a merger that results in the Company’s voting securities continuing to represent 50% or more of the combined 
voting power of the surviving entity and the Board of Directors immediately prior to the merger or consolidation 
continuing  to  represent  at  least  a  majority  of  the  Board  of  Directors  of  the  surviving  entity  or  (B)  a  merger  or 
consolidation effected to implement a recapitalization in which no person is or becomes the owner of voting securities 
representing more than 50% of the combined voting power of the Company; or (iv) shareholders approve of a plan of 
liquidation or dissolution.  The definition of change in control under the 2012 Amended Plan is similar to that of the 
2019 Plan, except that a change of control occurs if a person or entity becomes the beneficial owner of more than 25% 
or more of the voting power of the Company rather than 50% 

In the event of a change in control, unvested NQSOs and RPS shares immediately vest. The value of NQSOs is 
computed by multiplying the difference between the market value on December 31, 2023 and the exercise price 
of each option by the number of options subject to accelerated vesting. The December 31, 2023 value of  NQSOs 
35 

2024     WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
 
 
 
subject to accelerated vesting for each of the named executive officers is as follows: Messrs. Payne: $0; Thorson: 
$21,056;  Donohoe:  $18,236;  Rizzardi;  $17,014;  Baker:  $14,100.    The  value  of  RPS  shares  is  computed  by 
multiplying the market price at December 31, 2023 by the number of shares.  The value of RPS shares subject to 
accelerated vesting for each of the named executive officers is as follows: Messrs. Payne: $0; Thorson: $377,383; 
Donohoe: $329,434;  Rizzardi: $306,306; and Baker: $219,435.   

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 2023 for annual 
base salary for all named executive officers). Messrs. Payne, Thorson, Donohoe, Rizzardi, and Baker are eligible 
for  one  year’s  salary  under  the  plan.  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. 

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 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, were 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  made 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  and  Thorson  have  mortgage  loans  through  this  program.  The  largest  aggregate 
amounts of principal during 2023 were $266,085 and $133,489, respectively. The principal amounts outstanding 
at December 31, 2023 were $246,071 and $103,215, respectively. The rates of interest payable on the loans is 
5.75% and 5.875%, respectively.

PROPOSAL 2 – APPROVE A NON-BINDING ADVISORY VOTE ON THE 
COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS   

SEC  rules  requires  the  Company  to  permit  shareholders  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 most recent 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 88.1% of the shares voting on this proposal voted to support the Company’s executive compensation 
strategy.  

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 RPS and option awards are based on a minimum 
achievement of meeting the “threshold” level for each pre-established objective. Vesting of our RPS award is 
conditioned upon the achievement of performance criteria.  Both awards have a three-year vesting period. Our 
annual incentive plan incorporates at least four financial and/or strategic 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.  

Consistent with our pay-for-performance philosophy, the 2019 Plan and the 2012 Amended Plan, which  were 
approved by shareholders, include the following features: 

  disallow re-pricing stock options for poor stock performance; 
 

limits the number of shares that may be awarded; and 

Further, the 2019 Plan includes a clawback provision. 

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 2024 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

PROPOSAL 3 – RATIFY SELECTION OF INDEPENDENT AUDITOR   

Ratify Selection of Independent Auditor. At the Annual Meeting, shareholders will be asked to ratify the Audit 
Committee’s selection of Crowe LLP to serve as the Company’s independent auditors for the fiscal year ending 
December  31,  2024.    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 
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  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  LLP  with  respect  to  services  performed for 
fiscal 2023 and 2022 are as follows:

(1) Audit fees consisted of fees billed by Crowe 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 LLP for audits of certain employee benefits plans. 
(3) Tax fees consisted of fees billed by Crowe 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 
of the Audit Committee and approved prior to the completion of the audit by the Audit Committee. During fiscal 
year 2023, 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 

38 

2024   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
 
 
 
 
Committee  regarding  preapprovals  are  presented  to  the  full  Audit  Committee  at  its  next  meeting.  The  Audit 
Committee preapproved 100% of all services performed for the Company by Crowe LLP during fiscal year 2023.

REGISTERED PUBLIC ACCOUNTING FIRM

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 three 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 2023 and discussed them with Management and with Crowe 
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, 2023, 
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, 2023 for filing with the SEC.

EXHIBIT A 
Westamerica Bancorporation 
Audit Committee Charter – Reaffirmed January 24, 2024 

The Audit Committee is appointed by the Board to assist the Board of Directors (“Board”) in monitoring (1) the 
integrity of Westamerica Bancorporation’s (“Company”) financial statements, (2) the compliance by the Company 
with  legal  and  regulatory  requirements,  (3)  the  independence,  qualifications  and  performance  of  the  Company’s 
registered public accounting firms (“independent auditor” or “independent auditors”) preparing or issuing an audit 
report or performing other audit, review or attest services for the Company, (4) the Company’s Internal Audit and 
control function, and (5) the Company’s Loan Review function.  

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 Securities and Exchange Commission (“SEC”). No member shall be 
an affiliated person (as defined in relevant SEC or Nasdaq rules) of the Company or any of its subsidiaries or have 
participated at any time in the preparation of financial statements of the Company or any current subsidiary during the 
prior three years, and each member shall be free of any relationship that would interfere with the exercise of his or her 
independent judgment in carrying out the responsibilities of a member of the Audit Committee. The Audit Committee 
shall include members with banking or related financial management expertise who are able to read and understand 
fundamental financial statements, including the Company’s balance sheet, statement of income and comprehensive 
income, statement of changes in shareholders’ equity and statement of cash flows and at least one member must have 
the additional financial sophistication as required by and as defined in Nasdaq rules. 

The Committee shall be  subject  to the provisions of the Company’s bylaws relating to committees of the Board, 
including those provisions relating to removing committee members and filling vacancies. The members of the Audit 
Committee  and  its  Chair  shall  be  appointed  and  may  be  removed  by  the  Board  on  its  own  initiative  or  at  the 
recommendation of the Nominating Committee. The Audit Committee shall have no fewer than three members. If not 
designated by the Board, the Audit Committee may designate a member as its Chair.

The Audit Committee, in its capacity as a committee of the Board, shall be directly responsible for the appointment, 
compensation, retention, termination and oversight of the work of any independent auditors, and each independent 
auditor must report directly to the Audit Committee.  The Audit Committee, or its designee, will sign the independent 
auditor engagement letter. The Audit Committee shall be directly responsible for the resolution of disagreements 
between management and the independent auditor regarding financial reporting.   

The Audit Committee shall have the authority to retain independent legal, accounting or other advisors as it deems 
necessary to carry out its duties. The Company shall provide for appropriate funding, as determined by the Audit 
Committee, for payment of compensation to any independent auditor engaged for the purpose of preparing or issuing 
an audit report or performing other audit, review or attest services, compensation to any advisors employed by the 
Audit  Committee,  and  ordinary  administrative  expenses  that  the  Audit  Committee  deems  to  be  necessary  or 
appropriate in carrying out its duties. 

The Audit Committee may request any officer or employee of the Company or the Company’s outside counsel or 
independent auditor to attend a meeting of the Audit Committee. 

The Audit Committee shall pre-approve all auditing services and permitted non-audit services and fees to be paid for 
such services to be performed for the Company by its independent auditor, subject to the limited de minimis exceptions 
for non-audit services described in Section 10A of the Securities Exchange Act of 1934, provided that compliance 
with the limitations and procedural requirements of Section 10A is fulfilled. The Audit Committee may delegate to 
one or more designated members of the Committee the authority to grant pre-approvals of non-audit services and fees. 
Any such pre-approval shall be presented to the full Audit Committee at its next scheduled meeting. 

The Audit Committee shall make regular reports to the Board. 

The Audit Committee shall have the authority to conduct investigations that are related to its responsibilities under 
this Charter or otherwise assigned to it by the Board. 

In addition, the Audit Committee, to the extent that it deems necessary or appropriate shall:

2.  Review the annual audited financial statements with management and the independent auditor, including

3.  Review  with  management  and  the  independent  auditor  any  significant  financial  reporting  issues  and

2002, of evidence of material violations of securities laws or breaches of fiduciary duty or similar violations 
by the Company or one of its agents. 

39.  The Audit Committee must report to the Employee Benefits and Compensation Committee of the Board any

FORWARD-LOOKING STATEMENTS 

This  Report  on  Form  10-K  contains  forward-looking  statements  about  Westamerica  Bancorporation  for  which  it  claims  the 
protection of the safe harbor provisions contained in the Private Securities Litigation Reform Act of 1995.  

Examples of forward-looking statements include, but are not limited to: (i) projections of revenues, expenses, future credit quality 
and  performance,  the  appropriateness  of  the  allowance  for  credit  losses,  loan  growth  or  reduction,  mitigation  of  risk  in  the 
Company’s loan and investment securities portfolios, income or loss, earnings or loss per share, the payment or nonpayment of 
dividends, stock repurchases, capital structure and other financial items; (ii) statements of plans, objectives and expectations of the 
Company  or  its  management  or  board  of  directors,  including  those  relating  to  products  or  services;  (iii) statements  of  future

statements. 

These  forward-looking  statements  are  based  on  the  current  knowledge  and  belief  of  the  management  (“Management”)  of 
Westamerica  Bancorporation  (the  “Company”)  and  include  information  concerning  the  Company’s  possible  or  assumed  future 
financial condition and results of operations. 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 any 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 riots, terrorist threats and attacks on the United States, the actions taken 
in response, and the uncertain effect of these events on the local, regional and national economies; (6) changes in the interest rate 
environment and monetary policy; (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, 
particularly the impact of rising interest rates on the Company’s securities portfolio; (11) asset/liability management risks; (12) 
liquidity risks including the impact of recent adverse developments in the banking industry; (13) the effect of climate change, 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; (14) changes in the securities markets; (15) the duration and severity 
of  pandemics  and  governmental  and  customer  responses;  (16)  inflation  and  (17)  the  outcome  of  contingencies,  such  as  legal 
proceedings. However, the reader should not consider the above-mentioned factors to be a complete set of all potential risks or 
uncertainties. 

Forward-looking statements speak only as of the date they are made. The Company undertakes no obligation to update any forward-
looking statements in this report to reflect circumstances or events that occur after the date forward looking statements are made, 
except as may be required by law. The reader is directed to Part II – Item 1A “Risk Factors” of this report and other risk factors 
discussed elsewhere in this report, for further discussion of factors which could affect the Company's business and cause  actual 
results to differ materially from those expressed in any forward-looking statement made in this report. 

ITEM 1. 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. Its principal 
administrative offices are located at 4550 Mangels Boulevard, Fairfield, California 94534, its telephone number is (707) 863-6000 
and  its  website  address  is  www.westamerica.com.  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 (the “Bank”). The Bank 
is a California-chartered commercial bank whose deposit are insured by the Federal Deposit Insurance Corporation (the “FDIC”) 
up to applicable limits. 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 
stock in exchange for all of the outstanding shares of the acquired institutions. The subsidiary banks acquired were merged with 
and into the Bank. 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. 

In 2009 and 2010, the Bank acquired the banking operations of  two failed banks, the former County Bank and Sonoma Valley 
Bank, from the Federal Deposit Insurance Corporation (“FDIC”). The acquired assets and assumed liabilities from the FDIC were 
measured  at  estimated  fair  values,  as  required  by  Financial  Accounting  Standards  Board  (“FASB”)  Accounting  Standards 
Codification (“ASC”) 805, Business Combinations.  

At December 31, 2023, the Company had consolidated assets of approximately $6.4 billion, deposits of approximately $5.5 billion 
and shareholders’ equity of approximately $773 million.  

The  Company  assesses  and  is  careful  to  address  potential  health,  safety,  and  environmental  risks.  The  Company  cares  for  the 
environment and works to mitigate pollution and the potential risks related to climate change by implementing practices such as 
recycling and reusing materials, and controlling energy usage. 

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:

Human Capital Resources 

The  Company  and  its  subsidiaries  employed  641  full-time  equivalent  staff  or  669  employees  as  of  December  31,  2023.  The 
employees are not represented by a collective bargaining unit, and the Company believes its relationship with its employees is good.  

The Company’s ability to attract and retain employees is a key to its success. Employees receive a comprehensive benefits package 
that includes paid time off, sick time, company contributions of up to 6% to qualified retirement plans, discretionary profit-sharing 
retirement plan contributions, and other health and wellness benefits including participation in Company paid or subsidized medical, 
dental, term-life, accidental death and dismemberment (AD&D), long-term disability, and employee assistance programs.  Certain 
employees participate in one of the Company’s performance-based incentive programs, which may include additional bonus and 
incentive compensation, company contributions to supplemental retirement plans, and equity-based awards. Certain benefits are 
subject  to  eligibility,  vesting,  and  performance  requirements.  Employee  performance  is  measured  at  least  quarterly  and  formal 
performance evaluations are conducted at least annually. 

The Company’s code of ethics prohibits discrimination or harassment.  The Company requires all employees to agree to the code 
of ethics and participate in harassment prevention training annually.

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 that is subject to the BHCA. The Company files reports with and is subject to examination 
and supervision 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 Financial Protection and Innovation (the “Commissioner”). 

The FRB has significant supervisory and regulatory authority over the Company and its affiliates. Among other things, 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 
control of or to 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 
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 the FRB’s Regulation W and 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  Financial Protection and Innovation 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,  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. 

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. 

  Required  large,  publicly  traded  bank  holding  companies  to  create  a  risk  committee  responsible  for  the  oversight  of 

enterprise risk management. 

  Made permanent the $250 thousand limit for federal deposit insurance. 
  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 were less than $10 billion as of December 31, 2023, 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 adopted pursuant the Dodd-Frank Act, which are 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 
     - 5 -

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. 

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. As of December 31, 2023, the Company’s and the Bank’s 
respective regulatory capital ratios exceeded applicable regulatory minimum capital requirements. See Note 9 to the consolidated 
financial  statements  included  in  this  Report  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. 

In November 2019, the federal banking regulators published final rules implementing community bank leverage ratio, which is a 
simplified measure of capital adequacy for certain banking organizations that have less than $10 billion in total consolidated assets. 
A qualifying community banking organization that elects to use the community bank leverage ratio framework and that maintains 
a  leverage  ratio  of  greater  than  9%  is  considered  to  have  satisfied  the  generally  applicable  risk-based  and  leverage  capital 
requirements and, if applicable, is considered to have  met the  “well capitalized”  ratio requirements  for purposes of  its primary 
federal regulator’s prompt corrective action rules, discussed below. The Company does not have any immediate plans to elect to 
use the community bank leverage ratio framework but may make such an election in the future. 

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 Company’s ability to pay dividends depends in part on the Bank’s ability to pay cash dividends to the Company. 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 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 and FDIC Regulation 

Substantially all of the deposits of the Bank are insured up to applicable limits by the FDIC’s Deposit Insurance Fund (“DIF”) 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.  

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. 

Extraordinary growth in insured deposits during the first and second quarters of 2020 caused the DIF reserve ratio to decline below 
the statutory minimum of 1.35%. The Federal Deposit Insurance Act (the “FDI Act”) requires that the FDIC’s Board of Directors 
adopt a restoration plan when the DIF reserve ratio falls below 1.35% or is expected to within 6 months. Under the FDI Act, the 
restoration  plan  must  restore  the  reserve  ratio  to  at  least  1.35%  within  8  years  of  establishing  the  Plan,  absent  extraordinary 
circumstances. The FDIC established the following Restoration Plan (the “Plan”) on September 15, 2020.  

• 

• 

• 

The FDIC will monitor deposit balance trends, potential losses, and other factors that affect the reserve ratio; 

The FDIC will maintain the current schedule of assessment rates for all insured depository institutions; and 

At least semiannually, the FDIC will update its analysis and projections for the DIF and, if necessary, recommend any 
modifications to the Plan, such as increasing assessment rates. 

The Plan was amended in June 2022, to restore the DIF reserve ratio to at least 1.35% by September 30, 2028. On October 18, 2022 
the FDIC adopted a final rule to increase initial base deposit insurance assessment rates for insured depository institutions by 2

basis points, beginning with the first quarterly assessment period of 2023. The increased assessment rate schedules will remain in 
effect unless and until the reserve ratio of the DIF meets or exceeds 2%. A significant increase in DIF insurance premiums would 
have an adverse effect on the operating expenses and results of operations of the Bank. The Company cannot provide any assurance 
as to the effect of any future changes in its deposit insurance premium rates. 

While the FDIC is not Bank's primary federal regulator, as the insurer of the Bank's deposits, the FDIC is authorized to conduct 
examinations  of  and  to  require  reporting  by  FDIC-insured  institutions.  It  also  may  prohibit  any  FDIC-insured  institution  from 
engaging in any activity the FDIC determines by regulation or order poses a serious risk to the DIF. The FDIC also has authority to 
initiate enforcement actions against any FDIC-insured institution after giving its primary federal regulator the opportunity to take 
such action, and may seek to terminate the deposit insurance if it determines that the institution has engaged in unsafe or unsound 
practices  or  is  in  an  unsafe  or  unsound  condition.  Finally,  the  FDIC  may  terminate  deposit  insurance  upon  a  finding  that  the 
institution has engaged in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations, or has violated 
any applicable law, regulation, rule, order, or condition imposed by the FDIC. 

Economic Growth, Regulatory Relief and Consumer Protection Act 

On May 24, 2018, President Trump signed into law the first major financial services reform bill since the enactment of the Dodd-
Frank  Act. The  Economic  Growth,  Regulatory  Relief,  and  Consumer  Protection  Act  (the  “Relief  Act”)  modifies  or  eliminates 
certain requirements on community and regional banks and nonbank financial institutions.  For instance, under the Relief Act and 
related rule making: 

• 

• 

banks that have less than $10 billion in total consolidated assets and total trading assets and trading liabilities of less than 
five percent of total consolidated assets are exempt from Section 619 of the Dodd-Frank Act, known as the “Volcker 
Rule”, which prohibits “proprietary trading” and the ownership or sponsorship of private equity or hedge funds that are 
referred to as “covered funds”; and 

a new “community bank leverage ratio” was adopted, which is applicable to certain banks and bank holding companies 
with total assets of less than $10 billion (as described above under “Capital Standards”). 

Community Reinvestment Act and Fair Lending Laws 

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. In May 2022, the federal banking agencies released for public comment proposed rules to 
modernize CRA regulations. The Company continues to evaluate the impact of any changes to the CRA regulations. 

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. 

Anti-Money Laundering Laws  

The Bank Secrecy Act, as amended by the USA PATRIOT Act, gives the federal government powers to address money laundering 
and  terrorist  threats  through  enhanced  domestic  security  measures,  expanded  surveillance  powers  and  mandatory  transaction 
reporting obligations. The Bank Secrecy Act and related regulations require financial institutions to report currency transactions 
that exceed certain thresholds and transactions determined to be suspicious, establish due diligence requirements for accounts and

take  certain  steps  to  verify  customer  identification  when  accounts  are  opened.  The  Bank  Secrecy  Act  also  requires  financial 
institutions to develop and maintain a program reasonably designed to ensure and monitor compliance with its requirements, to 
train employees to comply with and to test the effectiveness of the program. Any failure to meet the requirements of the Bank 
Secrecy Act can result in the imposition of substantial penalties and in adverse regulatory action against the offending bank. 

The Anti-Money Laundering Act of 2020 (“AMLA”), which amends the Bank Secrecy Act, was enacted in January 2021. The 
AMLA is a comprehensive reform and modernization to U.S. bank secrecy and anti-money laundering laws. Among other things, 
it  codifies  a  risk-based  approach  to  anti-money  laundering  compliance  for  financial  institutions;  requires  the  development  of 
standards  for  evaluating  technology  and  internal  processes  for  Bank  Secrecy  Act  compliance;  expands  enforcement  and 
investigative  authority,  including  increasing  available  sanctions  for  certain  Bank  Secrecy  Act  violations  and  instituting  Bank 
Secrecy Act whistleblower incentives and protections. 

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)  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 its 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  

The  Bank’s  principal  competitors  for  deposits  and  loans  are  major  banks  and  smaller  community  banks,  savings  and  loan 
associations and credit unions. To a lesser extent, competitors include 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 offer 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. 

     - 9 -

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 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 
Federal Reserve Board (the” FOMC”), 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. 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 could realize losses if it were required to sell securities in its held-to-maturity securities portfolio to meet liquidity 
needs. 

As a result of increases in interest rates over the last year, the market value of previously issued government and other debt securities 
has  declined  significantly,  resulting  in  unrealized  losses  in  the  held-to-maturity  portion  of  the  Company’s  securities  portfolios. 
While the Company does not currently expect or intend to sell these securities, if the Company were required to sell such securities 
to meet liquidity needs, it may incur losses, which could impair the Company’s capital financial condition and results of operations. 
Further, while the Company has taken actions to maximize its funding sources, there is no guarantee that such funding sources will 
be available or sufficient in the event of sudden liquidity needs. 

Changes in capital market conditions could reduce asset valuations. 

Capital market conditions, including interest rates, 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. 

Negative  developments  affecting  the  banking  industry,  such  as  bank  failures,  may  have  a  material  adverse  effect  on  the 
Company. 

The banking industry could experience significant volatility with multiple bank failures during 2023. Industrywide concerns could 
develop related to liquidity, deposit outflows and unrealized losses on investment debt securities. While the Company cannot predict 
with certainty whether or how these developments may affect the banking industry, the Company faces the risks of increased FDIC 
deposit  insurance  premium  expenses;  increased  regulation  or  supervisory  scrutiny;  and  decreased  confidence  in  banks  among 
depositors and investors, any  of  which could, adversely affect the trading price  of  the  Company’s common  stock, its  ability to 
manage its liquidity or its ability to effectively fund its operations. Any one or a combination of such risk factors, or other factors, 
could materially adversely affect the Company's business, financial condition, results of operations and prospects.

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 and other equity awards 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 26.7 million shares of common stock were outstanding at December 31, 2023. Pursuant to its stock option plans, at 
December 31, 2023, the Company had outstanding options for 973 thousand shares of common stock, of which 614 thousand were 
currently exercisable. As of December 31, 2023, 705 thousand shares of Company common stock remained available for grants 
under the Company’s equity incentive 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 could repurchase shares of its common stock at price levels considered excessive.  

The  Company  may  repurchase  and  retire  its  common  stock  in  accordance  with  Board  of  Directors-approved  share  repurchase 
programs from time to time. 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 risk that borrowers may not pay interest or repay their loans as agreed is an inherent risk of the banking business. The Company 
strives to mitigate this risk by adhering to sound and proven underwriting practices, managed by experienced and knowledgeable 
credit professionals. Nonetheless, the Company may incur losses on loans that meet its underwriting criteria, and these losses may 
exceed the amounts set aside as reserves. 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 or its results of operations. 

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, 2023, real estate served as the principal source of collateral with respect to approximately 59% of 
the Company’s loan portfolio. The Company’s financial condition and operating results will be subject to changes in economic 
conditions in California. Much of the California real estate market could experience a decline in values of varying degrees. This 
decline could have 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 could recover more soundly from 
the recession than counties in the California “Central Valley,” from Sacramento in the north to Bakersfield in the south, where many 
of the Bank’s customers are located . Approximately 25% of the Company’s loans were to borrowers in the California “Central 
Valley” as of December 31, 2023. 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 and municipal governments’ budgetary and fiscal conditions. 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, fires, 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  wildfires, 
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, including inflation, 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 credit 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; and 
an increase in operating costs 

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, is highly dependent upon the business environment in the 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,  pandemics,  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 

     - 12 -

approval. 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. 

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. The Company’s ability to pay dividends is limited by banking and corporate laws, and depends, among other things, 
on  the  Company’s  regulatory  capital  levels  and  earnings  prospects,  as  well  as  the  Bank’s  ability  to  pay  cash  dividends  to  the 
Company.  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. 

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. 

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 the Bank’s 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 Company makes certain estimates and judgments in preparing its financial statements. For example, the Company maintains a 
reserve for potential loan defaults and non-performance. There is no precise method of predicting loans losses and determining the 
adequacy of the reserve requires the Company’s management to make a number of estimates and judgments.  If the estimates or 
judgments prove to be incorrect, the Company could be required to increase its provisions for credit losses, which could reduce its 
income or could cause it to incur operating losses in the future. The Company also uses models to estimate the effects of changing 
interest rates, which are based on estimates and assumptions that may prove to be inaccurate, particularly in times of market stress 
or unforeseen circumstances. Therefore, the quality and accuracy of management’s estimates and judgments will have an impact 
on the Company’s operating results and financial condition. For additional information, please see the discussion under “Item 7 
Management’s Discussion and Analysis of Financial Condition and Results of Operations  - Critical Accounting Policies” in this 
Report, which is incorporated by reference in this paragraph. 

The Company’s information systems or those of its vendors 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,  cybersecurity  incidents,  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 result in the loss or theft of customer or employee data, 
damage the  Company’s reputation, impair or disrupt  the Company’s business operations, 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. 

For example, during the second quarter 2023, the Company was notified that there may have been a compromise of a specific set 
of files processed by a third party vendor that could have affected a limited number of customers.  This incident did not occur on a 
Company system and the Company does not use the software that may have been compromised. The Company has implemented 
data  security  safeguards  with  its  third  party  vendors  designed  to  quickly  identify  and  contain  improper  access  to  sensitive 
information.  The  Company  notified  the  affected  customers  as  required  by  law.  As  of  December  31,  2023,  to  the  Company’s 
knowledge, there is no indication that any information has been subject to misuse as a result of the incident. 

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.

Operational Risks 

Climate change and the transition to renewable energy and a net zero emissions economy pose operational, commercial and 
regulatory risks. 

Climate change may increase the frequency or severity of extreme weather events, and if the Company is not adequately resilient 
to deal with acute climate events, its operations may be impacted. Extreme weather events could also impact the activities of its 
customers or third-party vendors. The physical commodities and assets underlying some of its markets or investments may also be 
impacted by climate change. 

Our  risk  management  practices  incorporate  the  challenges  brought  about  by  climate  change.  The  operations  conducted  in  our 
centralized facilities and branch locations can be disrupted by acute physical risks such as flooding and windstorms, and by chronic 
physical risks such as rising sea levels, sustained higher temperatures, drought, and increased wildfires. Over the intermediate and 
longer-term, the Company can be subject to transition risks such as market demand, and policy and law changes. 

None of the Company’s physical locations are located near sea level, and only a limited number of branches are located in flood 
zones. Our principal electricity supplier reports a Power Content Label of 100% greenhouse gas free using the California Energy 
Commission’s methodology. Our principal information technology vendor’s goal is to achieve 100 percent carbon neutrality for 
Scope 1 and 2 greenhouse gas emissions by 2025. The Company and its critical vendors maintain property and casualty insurance, 
and  maintain  and  regularly  test  disaster  recovery  plans,  which  include  redundant  operational  locations  and  power  sources. The 
Company’s operations do not use a significant amount of water in producing our products and services. 

The Company monitors the climate risks of our loan customers. Borrowers with real estate loan collateral located in flood zones 
must carry flood insurance under the loans’ terms. The Company has $18 million in loans to agricultural borrowers; Management 
continuously monitors these customers’ access to adequate water sources as well as their ability to sustain low crop yields without 
encountering financial hardship. The Company makes automobile loans; changes in consumer demand, or governmental laws or 
policies, regarding gasoline, electric and hybrid vehicles is not considered a risk to the Company’s automobile lending practices. 

The Company considers climate  risk  in  its  underwriting of corporate  bonds, and avoids  purchasing bonds of issuers,  which, in 
Management’s judgement, have elevated climate risk. 

In addition, the transition to renewable energy and a net zero emissions economy involves changes to consumer and institutional 
preferences for energy consumption, and other products and services, and the possible failure of its services to facilitate the needs 
of customers during the transition to renewable energy and changes in customer preferences could adversely impact its business 
and revenues. Changing preferences could also have an adverse impact on the operations or financial condition of its customers, 
which could result in reduced revenues from those customers. The Company is also subject to risks relating to new or heightened 
climate change-related regulations or legislation, which could impact its customers. 

The risks associated with climate change and the transition to renewable energy and a net zero emissions economy continue to 
evolve rapidly, and climate change-related risks may change or increase over time.    

The effects of pandemics and their impact are highly unpredictable and could be significant, and could harm the Company’s 
business, financial condition, and operating results. 

The Company’s business, operations and  financial performance  may be  affected by the  macroeconomic impacts resulting  from 
pandemics, and the Company’s financial results in future periods could differ significantly from the Company’s historical results. 
The extent to which the Company’s business will be affected will depend on a variety of factors, many of which are outside of the 
Company’s  control,  including  the  persistence  of  the  pandemic,  the  actions  of  governmental  authorities,  changes  in  customer 
preferences, impacts on economic activity, and the possibility of recession or financial market instability. 

If the Company loses the services of any of our key management personnel, its business could suffer. 

Our future success significantly depends on the continued service and performance of our key management personnel. Our senior 
management team has significant industry experience and would be difficult to replace. In particular, David L. Payne, our Chairman, 
President and Chief Executive Officer, has led the Company for over 30 years.  Competition for these employees is intense and we 
may not be able to attract and retain key personnel. If we are unable to attract or retain appropriately qualified personnel, we may 
not be successful in originating loans and servicing our customers, which could have a materially adverse effect on our business, 
financial condition and results of operations.

The Company competes with many banks and other traditional, non-traditional, brick and mortar and online financial service 
providers. 

Competition among providers of financial services in markets, particularly within California, is  intense. The Company competes 
with other financial and bank holding companies, state and national commercial banks, savings and loan associations, consumer 
finance companies, credit unions, securities brokerages, insurance companies, mortgage banking companies, money market mutual 
funds, asset-based non-bank lenders, government sponsored or subsidized lenders and other financial services providers. Many of 
these competitors have substantially greater financial resources, lending limits and technological resources than the Company and 
are able to offer a broader range of products and services. Many competitors offer lower interest rates and more liberal loan terms 
that appeal to borrowers but adversely affect net interest margin and assurance of repayment. The Company is increasingly faced 
with competition in many of its products and services by non-bank providers who may have competitive advantages of size, access 
to potential customers and fewer regulatory requirements, such as “fintech” lenders. Failure to compete effectively for deposit, loan 
and other banking customers in any of the lines of business could cause the Company to lose market share, slow or reverse growth 
rate or suffer adverse effects on financial condition, results of operations or profitability. 

The Company must continue to attract, retain and develop key personnel. 

The Company’s success depends to a significant extent upon its ability to attract, develop and retain experienced personnel in each 
of  its  lines  of  business  and  markets  including  managers  in  operational  areas,  compliance  and  other  support  areas  to  build  and 
maintain the infrastructure and controls required to support continuing growth. Competition for the best people in the industry can 
be intense, and there is no assurance that the Company will continue to attract or retain talent or develop personnel. Factors that 
affect its ability to attract, develop and retain key employees include compensation and benefits programs, profitability, ability to 
establish  appropriate  succession  plans  for  key  talent,  reputation  for  rewarding  and  promoting  qualified  employees  and  market 
competition  for  employees  with  certain  skills,  including  information  systems  development  and  security.  The  cost  of  employee 
compensation  is  a  significant  portion  of  operating  expenses  and  can  materially  impact  results  of  operations  or  profitability, 
especially during periods of wage inflation. The unanticipated loss of the services of key personnel could have an adverse effect on 
the business. 

The Company is subject to environmental liability risk associated with lending activities. 

A significant portion of our loan portfolio is secured by real property. During the ordinary course of business, we foreclose on and 
take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these 
properties. If hazardous or toxic substances are found, we may be liable for remediation costs, as well as for personal injury and 
property  damage.  Environmental  laws  may  require  us  to  incur  substantial  expenses  and  may  materially  reduce  the  affected 
property’s value or limit our ability to use or ability to sell the affected property. Environmental reviews of real property before 
initiating foreclosure actions may not be sufficient to detect all potential environmental hazards. The remediation costs and any 
other financial liabilities associated with an environmental hazard could have a material adverse effect on our business, financial 
condition and results of operations.

ITEM 1C. CYBERSECURITY  

The Company has developed and implemented an Information Security Program based on the Cybersecurity Framework (CSF) best 
practices and recommendations from the National Institute of Standards and Technology (NIST), applicable regulatory guidance, 
and  other  industry  standards.  Components  of  the  program  include  a  risk  assessment  program  to  identify,  assess,  and  mitigate 
cybersecurity  risk;  a  vendor  management  program  to  address  third-party  cybersecurity  risk;  and  an  incident  response  program 
documenting  cybersecurity  incident  response  and  notification  procedures.  The  Company's  Information  Security  Officer  (ISO) 
oversees  the  programs  and  reports  on  their  statuses  to  management  committees  including  the  Information  Security  Review 
Committee (ISRC) and the Information Systems Steering Committee (ISSC). The ISO has several years of professional experience 
in cybersecurity and vendor management, and holds multiple relevant professional certifications. The ISO provides an update to 
the Board of Directors on a quarterly basis. The Information Security Program is approved by the Board annually. 

The ISO maintains risk assessments for key IT systems. A third party cybersecurity risk assessment tool, as well as the FFIEC's 
Cybersecurity Assessment Tool (CAT) are also used annually to assess cybersecurity risk.

Third parties are assessed and categorized according to service type, compliance risk, financial risk, operational risk, and security 
risk. The level of due diligence and ongoing monitoring that is performed is based on inherent risk as well as specifics such as if 
the vendor hosts data in the cloud or has access to consumer information. 

The Company uses a training system to educate new and existing employees on cybersecurity risks. In addition to this training 
program, simulated phishing attempts are sent to employees on a regular basis to evaluate their understanding of these risks. 

The Company uses data loss prevention and web filtering software to ensure malicious data does not enter the Company's network, 
and  sensitive  information  does  not  leave  the  network  unless  properly  secured.  Penetration  tests  and  vulnerability  scanning  are 
performed on a regular basis. All Company networks are secured behind firewalls. Additionally, Security Information and Event 
Management (SIEM) technology, an Intrusion Detection System (IDS), and an Intrusion Prevention System (IPS) are used. 

Access to data on the Company's networks is granted only if needed for job functions. Data Security Analysts review changes to 
access to ensure they are authorized and appropriate. 

An Incident Response Committee that includes representatives from key areas of the Company meets in the event of cybersecurity 
incidents. The Committee ensures the proper notifications are made in order to comply with all relevant laws, rules and regulations. 

During the year ended December 31, 2023, there were no cybersecurity incidents that materially affected or are reasonably likely 
to materially affect the Company. For discussion of the risks from cybersecurity threats, including potential impact to the Company’s 
business strategy, results of operations, and financial condition, refer to “Item 1A – Risk Factors – The Company’s information 
systems may experience an interruption or breach in security” in this Report, which is incorporated by reference in this paragraph.   

ITEM 2. PROPERTIES  

Branch Offices and Facilities  

The Bank is engaged in the banking business through 77 branch offices in 20 counties in Northern and Central California. The Bank 
believes all of its offices are constructed and equipped to meet prescribed security requirements. 

The Company owns 28 banking office locations and one centralized administrative service center facility and leases 55 facilities. 
Most of the leases contain renewal options and provisions for rental increases, principally for changes in the cost of living index, 
and for changes in other operating costs such as property taxes and maintenance. 

ITEM 3. LEGAL PROCEEDINGS  

Due to the nature of its business, the Company is subject to various threatened or filed legal cases. Neither the Company nor any of 
its subsidiaries is a party to any material pending legal proceeding, nor is their property the subject of any material pending legal 
proceeding, other than ordinary routine legal proceedings arising in the ordinary course of the Company’s business. Based on the 
advice  of legal counsel, the  Company does not expect such cases  will have  a  material, adverse effect on its  business,  financial 
position or results of operations. Legal liabilities are accrued when obligations become probable and the amount can be reasonably 
estimated.

(1) Yields on securities and certain loans have been adjusted upward to a "fully taxable equivalent" ("FTE") basis in order to

reflect the effect of income which is exempt from federal income taxation at the current statutory tax rate.

(2) The efficiency ratio is defined as noninterest expense divided by total revenue (net interest income on an FTE basis and

noninterest income).

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 52 through 89, 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 credit losses on loans accounting to be a critical accounting estimate. 
The accounting for the allowance for credit losses on loans requires the most subjective or complex judgments, and as such could 
be most subject to revision as new information becomes available. The methodology, significant inputs and assumptions for the 
allowance  for  credit  losses  on  loans  are  discussed  in  the  section  “Allowance  for  Credit  Losses  on  Loans”  below.  Additional 
discussion of the factors affecting accounting for the allowance for credit losses on loans is included in the “Loan Portfolio Credit 
Risk” discussion below. The Company’s allowance for credit losses on loans is established to provide for expected losses based on 
the available estimates at that point in time. Changes in economic conditions could significantly impact the estimated losses and 
could materially affect the Company’s operating results. 

Financial Overview  

The Company reported net income of $161.8 million or $6.06 diluted earnings per common share (“EPS”) in 2023 compared with 
net income of $122.0 million or $4.54 EPS in 2022 and net income of $86.5 million or $3.22 EPS in 2021. 2023 results included a 
$1.2 million reversal of provision for credit losses, net of a $400 thousand provision for credit losses, a $279 thousand life insurance 
gain and a $492 thousand increase to reconcile the 2022 income tax provision to the filed  2022 tax returns. 2022 results included a 
$1.2 million reconciling payment from a payments network and a $930 thousand life insurance gain equivalent to combined EPS 
of $0.07. 2021 results included “make-whole” interest income on corporate bonds redeemed prior to maturity of $2.8 million. 

The Federal Open Market Committee of the Federal Reserve Board (“FOMC”) has tightened monetary policy through increases to 
the overnight federal funds interest rate starting in March 2022. On  January 31, 2024, the FOMC decided to maintain the target 
range for the federal funds rate at the range of 5.25% to 5.50%. The January 31, 2024 Federal Reserve press release stated, “Recent 
indicators suggest that economic activity has been expanding at a solid pace. Job gains have moderated since early last year but 
remain  strong,  and  the  unemployment  rate  has  remained  low.  Inflation  has  eased  over  the  past  year  but  remains  elevated.  The 
Committee seeks to achieve maximum employment and inflation at the rate of 2 percent over the longer run. The Committee judges 
that the risks to achieving its employment and inflation goals are moving into better balance. The economic outlook is uncertain, 
and Committee remains highly attentive to inflation risks. In support of its goals,  the Committee decided to maintain the target 
range for the federal funds rate at 5.25% to 5.50%. In considering any adjustments to the target range for the federal funds rate, the 
Committee will carefully assess incoming data, the evolving outlook, and the balance of risks. The Committee does not expect it 
will be appropriate to reduce the target range until it has gained greater confidence that inflation is moving sustainably toward 2 
percent…  The  Committee  would  be  prepared  to  adjust  the  stance  of  monetary  policy  as  appropriate  if  risks  emerge  that  could 
impede the attainment of the Committee’s goals.” The interest rate paid on reserve balances at the Federal Reserve Bank remained

at 5.40%. The Bank maintains reserve balances at the Federal Reserve Bank; the amount that earns interest is identified as “interest-
bearing cash”. 

Management continues to evaluate  the impacts of  inflation, the  Federal Reserve’s  monetary policy and climate  changes on the 
Company’s business and its customers. Recently, the banking industry experienced significant volatility with several regional bank 
failures in the first half of 2023. Industrywide concerns remained related to liquidity, deposit outflows and unrealized losses on debt 
securities. These events could adversely affect the Company’s funding of its operations. The extent of the impact on the Company’s 
results of operations, cash flow liquidity, and financial performance, as well as the Company’s ability to execute near- and long-
term business strategies and initiatives, will depend on numerous evolving factors and future developments, which are uncertain 
and cannot be reasonably predicted. 

The Company presents its net interest margin and net interest income on a fully taxable equivalent (“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 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 the Consolidated 
Financial Statements below) are fundamental to understanding the Company’s results of operations and financial condition. The 
Company adopted the following new accounting guidance: 

FASB ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, 
issued March 2022, eliminates the recognition and measurement guidance for troubled debt restructurings and requires enhanced 
disclosures about loan modifications for borrowers experiencing financial difficulty. This ASU also requires enhanced disclosure 
for loans that have been charged off. The ASU became effective January 1, 2023 under a prospective approach. The Company 
adopted the provisions to remove the recognition and measurement guidance for troubled debt restructurings and/or modify relevant 
disclosures  in the  “Loans” note to the consolidated financial statements. The requirement to include additional disclosures  was 
adopted by the Company January 1, 2023.  The additional disclosures did not affect the financial results upon adoption. 

FASB Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, 
was issued December 2019.  The ASU is intended to simplify various aspects related to accounting for income taxes, eliminates 
certain exceptions to the general principles in ASC Topic 740 related to intra-period tax allocation, simplifies  when companies 
recognize deferred taxes in an interim period, and clarifies certain aspects of the current guidance to promote consistent application. 
This guidance was effective for public entities for fiscal years beginning after December 15, 2020, and for interim period within 
those fiscal years, with early adoption permitted. The Company adopted the ASU provisions on January 1, 2021 and the adoption 
of the ASU provisions did not have a significant impact on the Company’s consolidated financial statements.

Net income for 2023 increased $39.7 million compared with 2022. Net interest and loan fee income (FTE) increased $59.9 million 
in 2023 compared with 2022 due to higher yield on interest-earning assets and higher average balances of investment debt securities, 
partially  offset  by  lower  average  balances  of  loans  and  interest-bearing  cash  and  higher  rate  on  interest-bearing  liabilities.  The 
Company recorded a $1.2 million reversal of provision for credit losses in 2023, reflecting a $2.2 million recovery on a previously 
charged off loan in the first quarter 2023 and a $400 thousand credit loss provision, based on the results of the Company’s current 
expected credit loss (“CECL”) model and  Management’s estimate  of credit losses over the remaining life of its loans and debt 
securities held to maturity. The Company provided no provision for credit losses in 2022, based on Management’s estimate of credit 
losses over the remaining life of its loans and debt securities held to maturity. Noninterest income in 2023 decreased $1.6 million 
compared with 2022 primarily because 2022 included a $1.2 million reconciling payment from a payments network and higher 
gains  on  life  insurance.  Noninterest  expense  in  2023  increased  $3.9  million  compared  with  2022  primarily  due  to  increases  in 
salaries and benefits, occupancy and equipment expenses, and increased FDIC insurance assessments for all insured depository 
institutions. Lower professional fees partially offset the increases in noninterest expense in 2023 compared with 2022. The tax rate 
(FTE) was 27.5% in 2023 and 27.2% in 2022. 2023 tax provision included a $492 thousand increase to reconcile the 2022 income 
tax provision to the filed  2022 tax returns. 

Net income for 2022 increased $35.5 million compared with 2021. Net interest and loan fee income (FTE) increased $47.6 million 
in 2022 compared with 2021 due to higher average balances of investment debt securities and higher yield on interest-earning assets, 
partially  offset  by  lower  average  balances  of  loans.  The  provision  for  credit  losses  was  zero  for  2022  and  2021,  reflecting 
Management's estimate of credit losses over the remaining life of its loans and investment debt securities.  Noninterest income in 
2022 increased $1.8 million compared with 2021 primarily due to a $1.2 million reconciling payment from a payments network, a 
$930 thousand life insurance gain and higher fee income on deposit accounts. The increases in 2022 compared 2021 was partially 
offset by decreases in merchant processing service income and other noninterest income. Noninterest expense in 2022 increased 
$1.6 million compared with 2021. Limited partnership operating losses increased $3.1 million due to higher estimated operating 
losses on limited partnership investments in low-income housing and occupancy and equipment expense increased primarily due to 
software upgrades. The increase in 2022 compared with 2021 was partially offset by a decrease in salaries and related benefits 
resulting from attrition and lower professional fees. The effective tax rate (FTE) was 27.2% in 2022 compared with 27.7% in 2021.

Net interest and loan fee income (FTE) increased $59.9 million in 2023 compared with 2022 due to higher yield on interest-earning 
assets (up 1.23%) and higher average balances of investment debt securities (up $31  million), partially offset by lower average 
balances of loans (down $86 million) and interest-bearing cash (down $486 million) and higher rate on interest-bearing liabilities 
(up 0.07%). 

Net interest and loan fee income (FTE) increased $47.6 million in 2022 compared with 2021 due to higher average balances of 
investment securities (up $723 million) and higher yield on interest-earning assets (up 0.55%), partially offset by lower average 
balances of loans (down $197 million). 

The net interest margin (FTE) was 4.37% in 2023, 3.17% in 2022 and 2.62% in 2021. The yield on earning assets (FTE) was 4.43% 
in 2023, 3.20% in 2022 and 2.65% in 2021. 

The  Company’s  funding  costs  were  0.06%  in  2023,  compared  with  0.03%  in  2022  and  2021.  Noninterest  bearing  deposits 
represented 47% of average deposits in 2023 and 2022, while higher-cost time deposits represented 2% for both periods. Average 
balances of time deposits in 2023 declined $24 million from 2022. Average balances of checking and saving deposits accounted for 
98.0% of average total deposits in 2023 compared with 97.8% in 2022. The customer deposits and shareholders’ equity fully funded 
the Company’s interest earning assets for 2023 and 2022; there was no borrowing from the Federal Reserve Bank or correspondent 
banks.

The increase in the Company’s yield on earning assets has been generated primarily by collateralized loan obligations (CLOs), held 
in debt securities available for sale portfolio, and interest-bearing cash. The CLOs have interest coupons that change once every 
three months by the amount of change in the three-month SOFR base rates. The average balances and yields of CLOs for 2023 and 
2022 was $1,543 million yielding 6.99% and $1,567 million yielding 3.62%, respectively. The interest-bearing cash yield changes 
by the amount of change in the overnight federal funds rate on the effective date declared by the FOMC. The average balance and 
yields of interest-bearing cash for 2023 and 2022 was $205 million yielding 5.21% and $691 million yielding 1.13%, respectively. 
The Company has other earning assets with variable yields such as commercial loans and lines of credit, consumer lines of credit

Balances, Yields/Rates and Interest Differential.” 

Summary of Average Balances, Yields/Rates and Interest Differential 

The following tables present information regarding the consolidated average assets, liabilities and shareholders’ equity, the amounts 
of interest income earned from average interest earning assets and the resulting yields, and the amounts of interest expense incurred 
on average interest-bearing liabilities and the resulting rates. 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 21 percent.

(1) Amounts calculated on an FTE basis using the current statutory federal tax rate.
(2) Net interest spread represents the average yield earned on interest-earning assets less the average rate incurred on interest-bearing
     liabilities.
(3) Net interest margin is computed by calculating the difference between interest income and expense, divided by the average balance
     of interest-earning assets. The net interest margin is greater than the net interest spread due to the benefit of noninterest-bearing
     demand deposits.

Provision for Credit 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  credit  losses  reflects 
Management's assessment of credit risk in the loan portfolio and debt securities held to maturity during each of the periods presented. 

The Company recorded a $1.2 million reversal of provision for credit losses in 2023 which reflected a $2.2 million recovery in the 
first quarter 2023 on a previously charged off loan and a $400 thousand provision for credit losses in the third quarter of 2023, 
based on the results of the CECL model and Management’s estimate of credit losses over the remaining life of its loans and debt 
securities held to maturity. The Company provided no provision for credit losses in 2022 and 2021 based on Management’s estimate 
of reserves needed over the remaining life of its loans and investments. For further information regarding credit risk, net credit 
losses and the allowance for credit losses, see the “Loan Portfolio Credit Risk” and “Allowance for Credit Losses” sections of this 
Report.

Noninterest income in 2023 decreased $1.6 million compared with 2022 primarily due to lower gains on life insurance and because 
debit card fees in 2022 included a $1.2 million reconciling payment from a payments network. Merchant processing service fees 
decreased in 2023 compared with 2022 primarily due to lower transaction volumes and increased lower-margin transactions. Service 
charges on deposit accounts decreased in 2023 compared with 2022 primarily due to lower fee income on analyzed deposit accounts, 
partially offset by fees generated from time deposits redeemed before maturity.  ATM  processing fee income increased in  2023 
compared with 2022 primarily due to increased transaction volumes. Other noninterest income in 2023 included higher recoveries 
of interest and fees on previously charged off loans compared 2022. 

Noninterest income in 2022 increased $1.8 million compared with 2021 primarily due to a $1.2 million reconciling payment from 
a payments network, a $930 thousand life insurance gain and higher fee income on deposit accounts. Higher fee income on deposit 
accounts in 2022 compared with 2021 was primarily attributable to increased fee income from overdrawn deposit accounts. The 
increases in 2022 compared 2021 were partially offset by decreases in merchant processing service income and other noninterest 
income.

Noninterest expense in 2023 increased $3.9 million compared with 2022. Salaries and benefits increased in 2023 compared with 
2022 due to increased staff, annual  merit increases and  higher group  health insurance costs  for the employees. Occupancy and 
equipment expenses increased in 2023 compared with 2022 primarily due to increases in repair and maintenance. Other noninterest 
expense increased in 2023 compared  with 2022 primarily  due to higher FDIC insurance assessments  for all insured depository 
institutions  and  losses  on  unauthorized  transactions  of  customer  debit  and  ATM  cards.  Professional  fees  decreased  in  2023 
compared with 2022 primarily due to lower legal fees. 

Noninterest  expense  in  2022  increased  $1.6  million  compared  with  2021.  Limited  partnership  operating  losses  increased  $3.1 
million  due  to  higher  estimated  operating  losses  on  limited  partnership  investments  in  low-income  housing.  Occupancy  and

equipment expense in 2022 increased primarily due to computer software upgrades. The increase in 2022 compared with 2021 was 
partially offset by a decrease in salaries and related benefits resulting from attrition. Professional fees decreased in 2022 compared 
with 2021 due to lower legal fees. 

Provision for Income Tax 

The Company’s income tax provision (FTE) was $61.4 million in 2023 compared with $45.5 million in 2022 and $33.2 million in 
2021. The 2023 income tax provision included a $492 thousand increase to reconcile the 2022 income tax provision to the filed 
2022 tax returns. The effective tax rates (FTE) were 27.5% in 2023 compared with 27.2% in 2022 and 27.7% in 2021. See Note 10 
to the consolidated financial statements for additional information related to income taxes.

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. 

At December 31, 2023, substantially all of the Company’s investment securities were investment grade as rated by one or more 
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’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.

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.  

During 2020 and the first six months of 2021, the Bank processed customer Payment Protection Program (“PPP”) loan applications 
as established by the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The United States Small Business 
Administration guarantees PPP loans; given this guarantee, the PPP loans are not considered to have default risk. PPP loans, net of 
deferred fees and costs, were $586 thousand at December 31, 2022 and $46 million at December 31, 2021. 

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. PPP loans are included in commercial loans. 

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. 

Loan volumes have declined due to payoffs and problem loan workout activities, 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 Company issues formal commitments on lines of credit to well-established and financially responsible commercial enterprises. 
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 that the borrowers will 
default, causing loss. 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 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  organizational  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 in order 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”).

At December 31, 2023, nonaccrual loans consisted of four loans with an average carrying value of $101 thousand and the largest 
carrying value was $192 thousand. 

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, pandemics, 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.

Allowance for Credit Losses on Debt Securities Held to Maturity 

Management segmented debt securities held to maturity, selected methods to estimate losses for each segment, and measured a loss 
estimate. Agency mortgage-backed securities were assigned no credit loss allowance due to the perceived backing of government 
sponsored  entities.  Corporate  securities  held  to  maturity  were  individually  evaluated  for  expected  credit  loss  by  evaluating  the 
issuer’s  financial  condition,  profitability,  cash  flows,  and  credit  ratings.  The  Company  has  evaluated  each  issuer’s  historical 
financial performance and ability to service debt payments throughout and following the 2008-2009 recession. The Company has 
an expectation that nonpayment of the amortized cost basis continues to be zero. At December 31, 2023, no credit loss allowance 
was assigned to corporate securities held to maturity based on evaluation of each individual issuer’s historical financial performance 
throughout full business cycles. Municipal securities were evaluated for risk of default based on credit rating and remaining term 
to maturity using Moody’s risk of default factors; Moody’s loss upon default factors were applied to the assumed defaulted principal 
amounts to estimate the amount for credit loss allowance. Allowance for credit losses related to debt securities held to maturity was 
$1 thousand related to municipal securities at December 31, 2023 and December 31, 2022, reflecting the expected credit losses on 
debt securities held to maturity. 

Allowance for Credit Losses on Loans 

The  Company’s  allowance  for  credit  losses  on  loans  represents  Management’s  estimate  of  forecasted  credit  losses  in  the  loan 
portfolio based on the current expected credit loss model. In evaluating credit risk for loans, Management measures the 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  preparation  of  the  financial  statements  requires  Management  to  estimate  the  amount  of  expected  losses  over  the  expected 
contractual life of the Bank’s existing loan portfolio and establish an allowance for credit losses. Loan agreements generally include 
a maturity date, and the Company considers the contractual life of a loan agreement to extend from the date of origination to the 
contractual maturity date. In estimating credit losses, Management must exercise significant judgment in evaluating information 
deemed relevant. 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 are charged 
to the allowance for credit 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 expected losses based on  historical loss rates adjusted for current  and 
expected conditions over a forecast period. 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, or credit protection agreements and other factors.  

Loans  that  share  common  risk  characteristics  are  segregated  into  pools  based  on  common  characteristics,  which  is  primarily 
determined by loan, borrower, or collateral type. Historical loss rates are determined for each pool. For consumer installment loans, 
primarily secured by automobiles, historical loss rates are determined using a vintage methodology, which tracks losses based on 
period of origination. For commercial, construction, and commercial real estate, historical loss rates are determined using an open 
pool methodology where losses are tracked over time for all loans included in the pool at the historical measurement date. Historical 
loss rates are adjusted for factors that are not reflected in the historical loss rates 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, estimated losses based on 
management’s reasonable and supportable expectation of economic trends over a forecast horizon of up to two years, and other

factors that impact credit loss expectations that are not reflected in the historical loss rates. Other factors include, but are not limited 
to, the effectiveness of the Company’s loan review system, adequacy of lending Management and staff, loan policies and procedures, 
problem loan trends, and concentrations of credit. At the end of the two-year forecast period loss rates revert immediately to the 
historical loss rates. The results of this analysis are applied to the amortized cost of the loans included within each pool.   

Loans that do not share risk characteristics with other loans in the pools are evaluated individually. A loan is considered ‘collateral-
dependent’ when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through 
the operation or sale of the collateral. A credit loss reserve for collateral-dependent loans is established at the difference between 
the amortized cost basis in the loan and the fair value of the underlying collateral adjusted for costs to sell. For other individually 
evaluated loans that are not collateral dependent, a credit loss reserve is established at the difference between the amortized cost 
basis in the loan and the present value of expected future cash flows discounted at the loan’s effective interest rate. The impact of 
an expected modification to be made to loans to borrowers experiencing financial difficulty is included in the allowance for credit 
losses when management determines such modification is likely. 

Accrued interest is recorded in other assets and is excluded from the estimation of expected credit loss.  Accrued interest is reversed 
through interest income when amounts are determined to be uncollectible, which generally occurs when the underlying receivable 
is placed on nonaccrual status or charged off.

Climate-Related Financial Risk  

Climate change presents risk to the Company, our critical vendors and our customers. Our risk management practices incorporate 
the challenges brought about by climate change. The operations conducted in our centralized facilities and branch locations can be 
disrupted by acute physical risks such as flooding and windstorms, and by chronic physical risks such as rising sea levels, sustained 
higher  temperatures,  drought,  and  increased  wildfires.  Over  the  intermediate  and  longer-term,  the  Company  can  be  subject  to 
transition risks such as market demand, and policy and law changes. 

None of the Company’s physical locations are located near sea level, and only a limited number of branches are located in flood 
zones. Our principal electricity supplier reports a Power Content Label of 100% greenhouse gas free using the California Energy 
Commission’s methodology. Our principal information technology vendor’s goal is to achieve 100 percent carbon neutrality for 
Scope 1 and 2 greenhouse gas emissions by 2025. The Company and its critical vendors maintain property and casualty insurance, 
and  maintain  and  regularly  test  disaster  recovery  plans,  which  include  redundant  operational  locations  and  power  sources. The 
Company’s operations do not use a significant amount of water in producing our products and services. 

The Company monitors the climate risks of our loan customers. Borrowers with real estate loan collateral located in flood zones 
must carry flood insurance under the loans’ terms. At December 31, 2023, the Company had $18 million in loans to agricultural 
borrowers; Management continuously monitors these customers’ access to adequate water sources as well as their ability to sustain

governmental  laws  or  policies,  regarding  gasoline,  electric  and  hybrid  vehicles  are  not  considered  to  be  material  risks  to  the 
Company’s automobile lending practices. 

The Company considers climate  risk  in  its  underwriting of corporate  bonds, and avoids  purchasing bonds of issuers,  which, in 
Management’s judgement, have elevated climate risk. 

While the Company follows risk management practices related to climate risk, the Company may experience financial losses due 
to climate risk despite these precautions. 

Asset/Liability and Market Risk Management 

Asset/liability management involves the evaluation, monitoring and management of interest rate risk, market risk, liquidity and 
funding. 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. Financial instruments may mature or re-price at different times. Financial instruments 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 financial instruments may change as interest rates change. In addition, the changing 
levels  of  interest  rates  may  have  an  impact  on  bond  portfolio  volumes,  accumulated  other  comprehensive  (loss)  income,  loan 
demand and demand for various deposit products. 

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 FOMC. The monetary policies of the FOMC can influence the overall 
demand  for loans and  growth of deposits and the level of  interest rates earned on loans and investment securities and paid for 
deposits and other borrowings. The nature and impact of future changes in monetary policies are generally not predictable. 

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 market 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. 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, 
intermediate, and short-term interest rates. 

Management monitors the Company’s interest rate risk using a purchased simulation model, which is periodically assessed using 
supervisory  guidance  issued  by  the  Board  of  Governors  of  the  Federal  Reserve  System,  SR  11-7  “Guidance  on  Model  Risk 
Management.”  Management  measures  its  exposure  to  interest  rate  risk  using  a  dynamic  composition  simulation  and  static 
simulation. Within the dynamic composition simulation, Management makes assumptions regarding the expected change  in the 
volume of financial instruments given the assumed change in market interest rates. Within the static simulation, cash flows are 
assumed redeployed into like financial instruments at prevailing rates and yields. Both simulations are used to measure expected 
changes in net interest income assuming various levels of change in market interest rates.  

The  Company’s  asset  and  liability  position  was  generally  “asset  sensitive”  at  December  31,  2023,  based  on  the  interest  rate 
assumptions applied to the simulation model. An “asset sensitive” position results in a larger change in interest income than in 
interest  expense  resulting  from  application  of  assumed  interest  rate  changes.  However,  in  the  dynamic  simulation,  an  assumed 
decline  in  interest  rates  is  expected  to  result  in  improved  deposit  balances  funding  higher  earning  asset  levels.  Further,  in  the 
dynamic simulation, no change in interest rates is expected to result in a decline in net interest income as asset yields remain stable 
and deposit costs rise as the Bank negotiates deposit rates with customers in the current environment. 

At December 31, 2023, Management’s most recent measurements of estimated changes in net interest income were:

Simulation  estimates  depend  on,  and  will  change  with,  the  size  and  mix  of  the  actual  and  projected  composition  of  financial 
instruments at the time of each simulation. Assumptions made in the simulation may not materialize and unanticipated events and 
circumstances may occur. In addition, the simulation does not take into account any future actions Management may undertake to 
mitigate the impact of interest rate changes, loan prepayment estimates and spread relationships, which may change regularly. 

The Company does not currently engage in trading activities or use derivative instruments to manage 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. Preferred or common stock holdings, as permitted by banking regulations, can fluctuate 
in value. Changes in value of preferred or common stock holdings are recognized 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 at times 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.  Finally,  the  amount  of 
compensation expense and tax deductions 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 credit 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 establish or increase reserves 
for expected credit losses. 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 Bank's 
operations and meet obligations and other commitments on a timely basis and at a reasonable cost. The Bank achieves this objective 
through  the  selection  of  asset  and  liability  maturity  mixes  that  it  believes  best  meet  its  needs.  The  Bank's  liquidity  position  is 
enhanced by its ability to raise additional funds as needed by borrowing from correspondent banks or in the wholesale markets, or 
by selling debt securities available for sale. 

In recent  years, the Bank's deposit base has provided the majority of the Bank's funding requirements. This low-cost source of 
funds, along with shareholders' equity, provided 97% of funding for average total assets in the year ended December 31, 2023 and 
December 31, 2022, respectively. The Bank’s funding from customer deposits is in part reliant on the confidence clients have in 
the  Bank.  The  Bank  places  a  very  high  priority  in  maintaining  this  confidence  through  conservative  credit  risk  and  capital 
management practices and by maintaining an appropriate level of liquidity. 

Total deposits were $5,474 million at December 31, 2023 and $6,225 million at December 31, 2022. Total time deposits were $97 
million at December 31, 2023 and $131 million at December 31, 2022. The Company has no foreign time deposits. The standard 
FDIC deposit insurance amount is $250,000 per depositor, for each account ownership category. At December 31, 2023, estimated 
federally uninsured deposits and time deposits were $2,544 million and $4 million, respectively. 

Banking industry deposits, including for Westamerica Bank, grew rapidly in 2020 and 2021 due to the injection of fiscal stimulus 
into the United States economy, including Paycheck Protection Program loans, and an easing of Federal Reserve monetary policy, 
both in response to the COVID pandemic. Federal Reserve monetary policy easing included reduction in the federal funds rate to a 
range of 0.00% to 0.25% and net purchases of Treasury securities and agency mortgage-backed securities, which increase the money 
supply and aggregate bank deposits. Subsequently, inflation rose considerably while employment conditions remained strong. In

2022 and 2023, the Federal Reserve’s monetary policy reversed to tightening, in an effort to reduce inflation. The monetary policy 
tightening included increasing  and keeping  the federal funds rate  to a range of 5.25% to 5.50% and net reductions of Treasury 
securities  and  agency  mortgage-backed  securities,  which  reduce  the  money  supply  and  aggregate  bank  deposits.  Westamerica 
Bank’s deposit totals are subject to both the fiscal policies of the United States government and monetary policies of the Federal 
Reserve; the 2023 decline in Westamerica Bank deposits is influenced by these fiscal and monetary policies. In addition, the Internal 
Revenue Service (“IRS”) declared every county in which Westamerica Bank operates as Natural Disaster Areas due to 2022-2023 
winter storms; the IRS and California Franchise Tax Board extended the 2022 tax filing deadline and 2023 tax installment payment 
due dates to November 16, 2023. As Westamerica Bank management expected this deferment of tax payment deadlines impacted 
deposit totals in the fourth quarter 2023 as customers paid their federal and California tax obligations. 

The following table shows the time remaining to maturity of the Company’s estimated amounts of uninsured time deposits with a 
balance greater than $250,000 per depositor per category:

Liquidity is further provided by assets such as balances held at the Federal Reserve Bank, investment securities, and amortizing 
loans. At December 31, 2023, the Company had $190,314 thousand in cash balances. During the twelve months ending December 
31, 2024, the Company expects to receive $265,000 thousand in principal payments from its debt securities. If additional operational 
liquidity  is  required,  the  Company  can  pledge  debt  securities  as  collateral  for  borrowing  purposes;  at  December  31,  2023,  the 
Company’s debt securities which qualify as collateral for borrowing totaled $3,915,867 thousand. In the ordinary course of business, 
the Company pledges debt securities as collateral for certain depository customers; at December 31, 2023, the Company had pledged 
$708,439  thousand  in  debt  securities  for  depository  customers.  In  the  ordinary  course  of  business,  the  Company  pledges  debt 
securities as collateral for borrowing from the Federal Reserve Bank; at December 31, 2023, the Company had pledged $996,935 
thousand  in  debt  securities  at  the  Federal  Reserve  Bank.  During  the  year  ended  December  31,  2023,  the  Company’s  average 
borrowings from the Federal Reserve Bank and other correspondent banks were $-0- thousand, respectively, and at December 31, 
2023, the Company’s borrowings from the Federal Reserve Bank and other correspondent banks were $-0- thousand. At December 
31, 2023, the Company’s estimated unpledged collateral qualifying debt securities totaled $1,945,176 thousand based on the Federal 
Reserve Bank borrowing programs. On January 24, 2024, the Federal Reserve Board announced the Bank Term Funding Program 
would cease making new loans as scheduled on March 11, 2024. Debt securities eligible as collateral are shown at market value

Liquidity risk can result from the mismatching of asset and liability cash flows, or from disruptions in the financial markets. The 
Bank performs liquidity stress tests on a periodic basis to evaluate the sustainability of its liquidity. Under the stress testing, the 
Bank  assumes  outflows  of  funds  increase  beyond  expected  levels.  Measurement  of  such  heightened  outflows  considers  the

composition  of  the  Bank’s  deposit  base,  including  any  concentration  of  deposits,  non-deposit  funding  such  as  short-term 
borrowings, and unfunded lending commitments. The composition of the Bank’s deposits is considered including the broad industry 
and geographic diversification in the Bank’s market area. The Bank 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 any 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. However, no assurance can be given the Bank will not experience a period of reduced liquidity. 

Management continually monitors the Bank’s cash levels. Loan demand from credit worthy borrowers will be dictated by economic 
and  competitive  conditions.  The  Bank  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 Bank's sales efforts, delivery of superior customer service, new regulations and market conditions. 
The Bank does not aggressively solicit higher-costing time deposits. Changes in interest rates, most notably rising interest rates or 
increased  consumer  spending,  could  impact  deposit  volumes.  Depending  on  economic  conditions,  interest  rate  levels,  liquidity 
management and a variety of other conditions, any 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 the 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 had no debt as of December 31, 2023. Substantially all of 
the Parent Company's revenues are obtained from subsidiary dividends and service fees.  

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 $46 million in the year ended December 31, 2023 
and $45 million in the year ended December 31, 2022 and retire common stock in the amounts of $14 million and $218 thousand, 
respectively. 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. The Parent Company’s cash balance was $155 million at December 31, 2023 and $99 million at December 31, 2022. 

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”) was 18.1% for the year ended December 
31, 2023 and 15.2% for the year ended December 31, 2022. The Company also raises capital as employees exercise stock options. 
Capital raised through the exercise of stock options was $950 thousand in the year ended December 31, 2023 and $2.3 million in 
the year ended December 31, 2022. 

The Company paid common dividends totaling $46 million in the year ended December 31, 2023 and $45 million in the year ended 
December 31, 2022, which represent dividends per common share of $1.72 and $1.68, 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 at times repurchased and retired its common stock as another means to return capital to shareholders. 
The  Company  repurchased  and  retired  274  thousand  shares  valued  at  $14  million  in  the  year  ended  December  31,  2023  and 3 
thousand shares valued at $218 thousand in the year ended December 31, 2022. 

The Company's primary capital resource is shareholders' equity, which was $773 million at December 31, 2023 compared with 
$602 million at December 31, 2022. The Company's ratio of equity to total assets was 12.14% at December 31, 2023 and 8.7% at 
December 31, 2022. 

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,  and  unanticipated  asset 
devaluations. 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.

The Company and the Bank routinely project capital levels by analyzing forecasted earnings, credit quality, shareholder dividends, 
asset volumes, share repurchase activity, stock option exercise proceeds, and other factors. Based on current capital projections, the 
Bank expects to maintain regulatory capital levels in excess of the minimum required to be considered well-capitalized under the 
prompt corrective action framework. The Company expects to continue paying quarterly dividends to shareholders. No assurance 
can be given that changes in capital management plans will not occur.

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. Average balances of higher costing time deposits declined 24% to $116 million from 2021

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET 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. 

Credit risk and interest rate risk are the most significant market risks affecting the Company, and equity price risk can also affect 
the Company’s financial results. These risks are described in the preceding sections regarding “Loan Portfolio Credit Risk,” and 
“Asset/Liability and Market Risk Management.” Other types of market risk, such as foreign currency exchange risk and commodity 
price risk, are not significant in the normal course of the Company’s business activities. 

Operational  risk  is  the  risk  to  current  or  projected  financial  condition  and  resilience  arising  from  inadequate  or  failed  internal 
processes or systems, people (including human errors or misconduct), or adverse external events, including the risk of loss resulting 
from breaches in data security. Operational risk can also include the risk of loss due to failures by third parties with which the 
Company does business.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING  

Management of Westamerica Bancorporation and  subsidiaries (the “Company”) is responsible for establishing and  maintaining 
adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over 
financial reporting as of December 31, 2023. 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, 2023 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, 2023 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 the Company’s internal control 
over financial reporting. Their opinion and attestation on internal control over financial reporting appear on page 90.

WESTAMERICA BANCORPORATION 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 1: Business and Accounting Policies 

Westamerica Bancorporation, a registered bank holding company (the “Company”), provides a full range of banking services to 
corporate and individual customers in Northern and Central California through its  wholly-owned subsidiary bank, Westamerica 
Bank (the “Bank”). 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. 

Management continues to actively evaluate the impacts of inflation, the Federal Reserve’s monetary policy and climate changes on 
the Company’s business. During the first half of 2023, the banking industry experienced significant volatility with  several bank 
failures. Industrywide concerns developed related to liquidity, deposit outflows and unrealized losses on investment debt securities. 
These events could adversely affect the Company’s ability to effectively fund its operations. Any one or a combination of such risk 
factors, or other factors, could materially adversely affect the Company's business, financial condition, results of operations and 
prospects. The extent of the impact on the Company’s results of operations, cash flow, liquidity, and financial performance, as well 
as  the  Company’s  ability  to  execute  near-  and  long-term  business  strategies  and  initiatives,  will  depend  on  numerous  evolving 
factors and future developments, which are highly uncertain and cannot be reasonably predicted. 

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  accounting  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, it is reasonably possible conditions could change materially affecting results 
of  operations  and  financial  conditions.  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, 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 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 
fair 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.  The allowance for credit losses 
accounting is an 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 the accounting for the allowance for credit losses on loans is 
included in the following “Loans” and “Allowance for Credit Losses” sections. Carrying assets and liabilities at fair value inherently 
results in 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 “Securities” 
section discusses the factors that may affect the valuation of the Company’s securities. Although the estimates contemplate current 
conditions actual results can change. 

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.

Equity  Securities.  Equity  securities  consist  of  marketable  equity  securities  and  mutual  funds  which  are  recorded  at  fair  value. 
Unrealized gains and losses are included in net income. There were no equity securities at December 31, 2023 and December 31, 
2022. 

Debt  Securities.  Debt  securities  consist  of  the  securities  of  government  sponsored  entities,  states,  counties,  municipalities, 
corporations, agency and non-agency mortgage-backed securities, collateralized loan obligations and commercial paper. Securities 
transactions  are  recorded  on  a  trade  date  basis.  The  Company  classifies  its  debt  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 net income. Held to maturity debt 
securities are those securities which the Company has the ability and intent to hold until maturity. Held to maturity debt 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 debt securities. Available for sale debt securities are recorded at fair value. Unrealized 
gains and losses, net of the related tax effect, on available for sale debt securities are included in accumulated other comprehensive 
income. Accrued interest is recorded within other assets and reversed against interest income if it is not received.   

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. 

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 credit loss. 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. 

To  the  extent  that  debt  securities  in  the  held-to-maturity  portfolio  share  common  risk  characteristics,  estimated  expected  credit 
losses are calculated in a manner like that used for loans held for investment. That is, for pools of such securities with common risk 
characteristics, the historical lifetime probability of default and severity of loss in the event of default is derived or obtained from 
external  sources  and  adjusted  for  the  expected  effects  of  reasonable  and  supportable  forecasts  over  the  expected  lives  of  the 
securities on those historical credit losses. Expected credit loss on each security in the held-to-maturity portfolio that do not share 
common  risk  characteristics  with  any  of  the  pools  of  debt  securities  is  individually  evaluated  and  a  reserve  for  credit  losses  is 
established at the difference between the discounted value of the expected future cash flows, based on the original effective interest 
rate, and the recorded amortized cost basis of the security. For certain classes of debt securities, the bank considers the history of 
credit losses, current conditions and reasonable and supportable forecasts, which may indicate that the expectation that nonpayment 
of the amortized cost basis is or continues to be zero. Therefore, for those securities, the bank does not record expected credit losses. 

Available for sale debt securities in unrealized loss positions are evaluated for credit related loss at least quarterly. For available for 
sale debt securities, a decline in fair value due to credit loss results in recording an allowance for credit losses to the extent the fair 
value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, 
such as declines due to changes in market interest rates, are recorded through other comprehensive income, net of applicable taxes. 
Although  these  evaluations  involve  significant  judgment,  an  unrealized  loss  in  the  fair  value  of  a  debt  security  is  generally 
considered to not be related to credit when the fair value of the 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 nor does it believe it will be required to sell the security before the recovery of its cost basis.   

If the Company intends to sell a debt security or more likely than not will be required to sell the security before recovery  of its 
amortized cost basis, the debt security is written down to its fair value and the write down is charged against the allowance for credit 
losses with any incremental loss reported in earnings. 

Purchase premiums are amortized to the earliest call date and purchase discounts are amortized to maturity 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  debt  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. 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. When the review indicates that impairment exists the asset value is reduced to fair value. 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 and included in other assets. 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 and commercial loans  to 
borrowers experiencing financial difficulties are placed on nonaccrual status 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. Nonaccrual 
loans are reinstated to accrual status when none of the loan’s principal and interest is past due and improvements in credit quality 
eliminate doubt as to the full collectability of both principal and interest, or the loan otherwise becomes well secured and  in the 
process of collection. Certain consumer loans or auto receivables are charged off against the allowance for credit losses when they 
become 120 days past due. 

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 expected losses over the expected 
contractual life of the Bank’s existing loan portfolio and establish an allowance for credit losses. Loan agreements generally include 
a maturity date, and the Company considers the contractual life of a loan agreement to extend from the date of origination to the 
contractual maturity date. In estimating credit losses, Management must exercise significant judgment in evaluating information 
deemed relevant. 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 are charged 
to the allowance for credit 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 expected losses based on  historical loss rates adjusted for current  and 
expected conditions over a forecast period. 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, or credit protection agreements and other factors.  

Loans  that  share  common  risk  characteristics  are  segregated  into  pools  based  on  common  characteristics,  which  is  primarily 
determined by loan, borrower, or collateral type. Historical loss rates are determined for each pool. For consumer installment loans, 
primarily secured by automobiles, historical loss rates are determined using a vintage methodology, which tracks losses based on 
period of origination. For commercial, construction, and commercial real estate, historical loss rates are determined using an open 
pool methodology where losses are tracked over time for all loans included in the pool at the historical measurement date. Historical 
loss rates are adjusted for factors that are not reflected in the historical loss rates 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, estimated losses based on 
management’s reasonable and supportable expectation of economic trends over a forecast horizon of up to two  years, and other 
factors that impact credit loss expectations that are not reflected in the historical loss rates. Other factors include, but are not limited 
to, the effectiveness of the Company’s loan review system, adequacy of lending Management and staff, loan policies and procedures,

problem loan trends, and concentrations of credit. At the end of the two-year forecast period loss rates revert immediately to the 
historical loss rates. The results of this analysis are applied to the amortized cost of the loans included within each pool. 

Loans that do not share risk characteristics with other loans in the pools are evaluated individually. A loan is considered ‘collateral-
dependent’ when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through 
the operation or sale of the collateral. A credit loss reserve for collateral-dependent loans is established at the difference between 
the amortized cost basis in the loan and the fair value of the underlying collateral adjusted for costs to sell. For other individually 
evaluated loans that are not collateral dependent, a credit loss reserve is established at the difference between the amortized cost 
basis in the loan and the present value of expected future cash flows discounted at the loan’s effective interest rate. The impact of 
an expected modification to be made to loans to borrowers experiencing financial difficulty is included in the allowance for credit 
losses when management determines such modification is likely. 

Accrued interest is recorded in other assets and is excluded from the estimation of expected credit loss.  Accrued interest is reversed 
through interest income when amounts are determined to be uncollectible, which generally occurs when the underlying receivable 
is placed on nonaccrual status or charged off. 

Liability for Off-Balance Sheet Credit Exposures. Off-balance sheet credit exposures relate to letters of credit and unfunded loan 
commitments for commercial, construction and consumer loans. The Company maintains a separate allowance for credit losses 
from  off-balance-sheet  credit  exposures,  which  is  included  within  other  liabilities  on  the  consolidated  statements  of  financial 
condition. Increases or reductions to the Company’s allowance for credit losses from off-balance sheet credit exposures are recorded 
in  other  expenses.  Management  estimates  the  amount  of  expected  losses  by  estimating  expected  usage  exposures  that  are  not 
unconditionally cancellable by the Company and applying the loss  factors used in the allowance for credit loss methodology to 
estimate the liability for credit losses related to unfunded commitments. No credit loss estimate is reported for off-balance-sheet 
credit exposures that are unconditionally cancellable by the Company or for undrawn amounts under such arrangements that may 
be drawn prior to the cancellation of the arrangement. 

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 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. 

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. 

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  finite  useful  lives  are  amortized  on  an  accelerated  basis  over  their  respective 
estimated useful lives not exceeding 15 years. Intangible assets with a finite useful life are reviewed at least annually for impairment. 
Any  goodwill  and  any  intangible  asset  acquired  in  a  business  combination  determined  to  have  an  indefinite  useful  life  is  not 
amortized and is reviewed at least annually for impairment. If management determines, based on a qualitative review of events and

circumstances, that it is more likely than not that the carrying value of the intangible asset will not be realized, an impairment test 
is performed to determine whether the asset’s fair value is less than the carrying amount of the asset.     

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-Based Compensation. 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. 

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. 

Recently Adopted Accounting Standards 

In the year ended December 31, 2021, the Company adopted the following new accounting guidance: 

FASB ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, was issued December 2019.  The 
ASU is intended to simplify various aspects related to accounting for income taxes, eliminates certain exceptions to the general 
principles in ASC Topic 740 related to intra-period tax allocation, simplifies when companies recognize deferred taxes in an interim 
period, and clarifies certain aspects of the current guidance to promote consistent application. This guidance effective for public 
entities for fiscal years beginning after December 15, 2020, and for interim period within those fiscal years, with early adoption 
permitted. The Company adopted the ASU provisions on January 1, 2021 and the adoption of the ASU provisions did not have a 
significant impact on the Company’s consolidated financial statements. 

In the year ended December 31, 2023, the Company adopted the following new accounting guidance: 

FASB ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, 
issued March 2022, eliminates the recognition and measurement guidance for troubled debt restructurings and requires enhanced 
disclosures about loan modifications for borrowers experiencing financial difficulty. This ASU also requires enhanced disclosure 
for loans that have been charged off. The ASU became effective January 1, 2023 under a prospective approach. The Company 
adopted the provisions to remove the recognition and measurement guidance for troubled debt restructurings and/or modify relevant 
disclosures  in the  “Loans”  note to the consolidated financial statements. The  requirement to include additional disclosures  was 
adopted by the Company January 1, 2023.  The additional disclosures did not affect the financial results upon adoption. 

Recently Issued Accounting Standards 

FASB  ASU  2020-04,  Reference  Rate  Reform  (Topic  848):  Facilitation  of  the  Effects  of  Reference  Rate  Reform  on  Financial 
Reporting, was issued March 2020. The ASU provides optional expedients and exceptions for applying GAAP to loan and lease 
agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest 
rate  benchmarks.  For  transactions  that  are  modified  because  of  reference  rate  reform  and  that  meet  certain  scope  guidance  (i)

modifications of loan agreements should be accounted for by prospectively adjusting the effective interest rate and the modification 
will be considered "minor" so that any existing unamortized origination fees/costs would carry forward and continue to be amortized 
and (ii) modifications of lease agreements should be accounted for as a continuation of the existing agreement with no reassessments 
of  the  lease  classification  and  the  discount  rate  or  remeasurements  of  lease  payments  that  otherwise  would  be  required  for 
modifications  not accounted for as separate  contracts. ASU 2020-04 also provides numerous optional expedients for derivative 
accounting. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date 
of Topic 848.” The ASU 2022-06 deferred the sunset date  of ASU 2020-04 to December 2024. Once elected for a Topic or an 
Industry  Subtopic  within  the  Codification,  the  amendments  in  this  ASU  must  be  applied  prospectively  for  all  eligible  contract 
modifications for that Topic or Industry Subtopic. The Company does not expect any material impact on its consolidated financial 
statements. 

FASB ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual 
Sale Restrictions, was issued June 2022. The ASU clarifies the guidance in Topic 820 when measuring the fair value of an equity 
security  subject  to  contractual  restrictions  that  prohibit  the  sale  of  an  equity  security.  Additionally,  the  ASU  requires  specific 
disclosures related to equity securities that are subject to contractual sale restrictions. The required disclosures include (1) the fair 
value of such equity securities reflected in the balance sheet, (2) the nature and remaining duration of the corresponding restrictions, 
and (3) any circumstances that could cause a lapse in the restrictions. The ASU is effective for fiscal years beginning after December 
15, 2023, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the 
impact of this ASU on its consolidated financial statements. 

FASB  ASU  2023-02,  Investments  –  Equity  Method  and  Joint  Ventures  (Topic  323):Accounting  for  Investments  in  Tax  Credit 
Structures Using the Proportional Amortization Method, was issued March 2023. The ASU expands the use of the proportional 
amortization method of accounting, currently only available to investments in low-income housing tax credit structures, to equity 
investments in other tax credit structures that meet certain criteria. The ASU also requires additional disclosures for any tax credit 
program where the proportional amortization method is elected. The ASU is effective for fiscal years beginning after December 15, 
2023, and interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact 
of this ASU on its consolidated financial statements.

Expected maturities of mortgage-related securities can differ from contractual maturities because borrowers have the right to call 
or prepay obligations with or without call or prepayment penalties. In addition, such factors as prepayments and interest rates may 
affect the yield on the carrying value of mortgage-related securities.

Based  upon  the  Company’s  December  31,  2023  evaluation,  the  unrealized  losses  on  debt  securities  were  caused  by  market 
conditions  for  these  types  of  securities.  Increasing  risk-free  interest  rates  have  caused  large  declines  in  bond  values  generally. 
Additionally, market rates for non-Treasury bonds are determined by the risk-free interest rate plus a risk premium spread; such 
spreads for investment grade, fixed rate, taxable corporate bonds have increased, also broadly reducing corporate bond values. The 
Company continually monitors interest rate changes, risk premium spread changes, credit rating changes for issuers of bonds owned, 
collateralized loan obligations’ collateral levels, and corporate bond issuers’ common stock price changes. All collateralized loan 
obligations and corporate securities were investment grade rated at December 31, 2023. 

The Company does not intend to sell any debt securities available for sale with an unrealized loss and has concluded that it is more 
likely than not that it will not be required to sell the debt securities prior to recovery of the amortized cost basis. 

The Company evaluates held to maturity corporate securities individually, monitoring each issuer’s financial condition, profitability, 
cash flows and credit rating agency conclusions. The Company has evaluated each issuer’s historical financial performance and 
ability  to  service  debt  payments  throughout  and  following  the  2008-2009  recession.  The  Company  has  an  expectation  that 
nonpayment of the amortized cost basis continues to be zero. 

The fair values of debt securities could decline in the future if interest rates increase, the general economy deteriorates, inflation 
increases, credit ratings decline, the issuers’ financial condition deteriorates, or the liquidity for debt securities declines. As a result, 
significant credit losses on debt securities may occur in the future. 

As of December 31, 2023 and December 31, 2022, the Company’s debt securities pledged to secure public deposits, Federal Reserve 
Bank  borrowings  and  short-term  borrowed  funds  had  a  carrying  amount  of  $2,034,706  thousand  and  $1,180,010  thousand,

The Company evaluates debt 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, collateral levels, 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. 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 following table presents the activity in the allowance for credit losses for debt securities held to maturity:

Agency mortgage-backed securities were assigned no credit loss allowance due to the perceived backing of government sponsored 
entities. Municipal securities were evaluated for risk of default based on credit rating and remaining term to maturity using Moody’s 
risk of default factors; Moody’s loss upon default factors were applied to the assumed defaulted principal amounts to estimate the 
amount  for  credit  loss  allowance.  Corporate  securities  held  to  maturity  were  individually  evaluated  for  expected  credit  loss  by 
evaluating  the  issuer’s  financial  condition,  profitability,  cash  flows,  and  credit  ratings.  At  December  31,  2023,  no  credit  loss 
allowance was assigned to corporate securities held to maturity.

The  Company’s  customers  are  primarily  small  businesses,  professionals  and  consumers.  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  the  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.” The Loan  Review Department performs continuous 
evaluations throughout the year. 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 following summarizes the credit risk profile by internally assigned grade:

(1) A bank applying for membership in the Federal Reserve System is required to subscribe to stock in the Federal Reserve Bank 
(FRB) in its district in a sum equal to six percent of the bank’s paid-up capital stock and surplus. One-half of the amount of the 
bank's subscription shall be paid to the FRB and the remaining half will be subject to call when deemed necessary by the Board 
of Governors of the Federal Reserve System. 

The Company owns 211 thousand shares of Visa Inc. (“Visa”) class B common stock which have transfer restrictions; the carrying 
value is $-0- thousand. Visa Inc. disclosed a revised conversion rate applicable to its class B common stock in its Form 8-K dated 
October 2, 2023. The conversion rate of class B common stock into class A common stock, which is unrestricted and trades actively 
on the New York Stock Exchange, was reduced from 1.5902 to 1.5875 per share, effective as of September 28, 2023. Visa class A 
common stock had a closing price of $260.35 per share on December 29, 2023, the last day of stock market trading for the fourth 
quarter 2023. The ultimate value of the Company’s Visa class B shares is subject to the extent of Visa Inc.’s future litigation escrow 
fundings, the resulting conversion rate to class A common stock, and current and future trading restrictions on the class B common 
stock. At its Annual Meeting held January 23, 2024, Visa proposed a Class B Exchange Offer Program authorizing Visa to conduct 
one or more exchange offers that would allow Class B stockholders to exchange portions of their Class B common stock into freely 
tradable shares. The proposal was approved by Visa stockholders. Under an initial exchange offer, current Class B shares will be 
exchanged into Class B-1 shares. In potential exchange offers, a Class B-1 stockholder can elect to exchange a portion of its Class 
B-1 shares for Class C common stock which is transferable and convertible to Class A common stock. Any exchange of Class B-1 
shares into Class C common stock requires the stockholder to execute an indemnification agreement with Visa for Visa’s related 
unresolved litigation. 

The Company invests in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for

investments totaled $34,421 thousand and $22,647 thousand of this amount represents outstanding equity capital commitments that 
are  included  in  other  liabilities.  At  December  31,  2023,  the  $15,561  thousand  of  outstanding  equity  capital  commitments  are 
expected to be paid as follows: $14,077 thousand in 2024, $600 thousand in 2025, $145 thousand in 2026, $189 thousand in 2027,

The Company has entered into leases for most branch locations and certain other offices that were classified as operating leases 
primarily with original terms of five years. Certain lease arrangements contain extension options, which can be exercised at  the 
Company’s option, for one or more additional five year terms. Unexercised extension options are not considered reasonably certain 
of exercise and have not been included in the lease term used to determine the lease liability or right-of-use asset. The Company 
did not have any finance leases as of December 31, 2023. 

As  of  December  31,  2023,  the  Company’s  lease  liability  and  right-of-use  asset  were  $18,814  thousand.  The  weighted  average 
remaining life of operating leases and weighted average discount rate used to determine operating lease liabilities were 3.7 years 
and 2.94%, respectively, at December 31, 2023.  The Company did not have any material lease incentives, unamortized initial direct 
costs, prepaid lease expense, or accrued lease expense as of December 31, 2023. 

Total lease costs of $6,604 thousand, $6,575 thousand and $6,581 thousand, during the year ended December 31, 2023, 2022 and 
2021, respectively, were recorded within occupancy and equipment expense. The Company did not have any material short-term

Note 6: Goodwill and Identifiable Intangible Assets 

The Company has recorded goodwill and other identifiable intangibles associated with purchase business combinations. Goodwill 
is not amortized, but is evaluated for impairment at least annually. The Company did not recognize impairment during the  year 
ended December 31, 2023 and December 31, 2022, as no triggering events occurred during such periods. Identifiable intangibles 
are amortized to their estimated residual values over their expected useful lives. Such lives and residual values are also periodically 
reassessed  to  determine  if  any  amortization  period  adjustments  are  indicated.  During  the  year  ended  December  31,  2023  and 
December 31, 2022, no such adjustments were recorded.

The Company grants stock options and restricted performance shares to employees in exchange for employee services, pursuant to 
the shareholder-approved 2019 Omnibus Equity Incentive Plan. Prior to shareholder approval of the 2019 Omnibus Equity Incentive 
Plan on April 25, 2019, the Company granted stock options and restricted performance shares under its  1995 Stock Option Plan, 
which was last amended and restated in 2012. Nonqualified stock option grants (“NQSO”) are granted with an exercise price equal 
to  the  fair  market  value  of  the  related  common  stock  on  the  grant  date.  NQSO  generally  become  exercisable  in  equal  annual 
installments over a three-year period with each installment vesting on the anniversary date of the grant. Each NQSO has a maximum 
ten-year term. A restricted performance share grant becomes vested after three years of being awarded, provided the Company has 
attained its performance goals for such three-year period.

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  year  ended 
December  31,  2023,  2022  and  2021,  the  Company  granted  225  thousand,  229  thousand,  and  193  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

(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, 2023 is 705 
thousand.

The estimated grant date fair value for options granted under the Company’s stock option plan during the twelve months ended 
December  31,  2023,  2022  and  2021  was  $8.50,  $7.90  and  $7.50  per  share,  respectively.  The  total  remaining  unrecognized 
compensation cost related to nonvested awards as of December 31, 2023 is $1,581 thousand and the weighted average period over 
which the cost is expected to be recognized is 1.7 years. 

The total intrinsic value of options exercised during the year ended December 31, 2023, 2022 and 2021 was $113 thousand, $165 
thousand and $454 thousand, respectively. The total fair value of Restricted Performance Shares (“RPSs”) that vested during the 
year ended December 31, 2023, 2022 and 2021 was $508 thousand, $492 thousand and $527 thousand, respectively. The total fair 
value of options vested during the year ended December 31, 2023, 2022 and 2021 was $1,309 thousand, $1,464 thousand and $1,783 
thousand,  respectively.  During  the  year  ended  December  31,  2023,  22  thousand  shares  were  issued  due  to  the  exercise  of 
nonqualified stock options resulting in a tax deduction less than the related share based compensation expense by $16 thousand. 
During  the  year  ended  December  31,  2022,  40  thousand  shares  were  issued  due  to  the  exercise  of  nonqualified  stock  options 
resulting in a tax deduction less than the related share based compensation expense by $143 thousand. The lesser deduction in 2022 
resulted in a $30 thousand increase in tax provision. During the year ended December 31, 2021, 53 thousand shares were issued 
due to the exercise of nonqualified stock options resulting in a tax deduction equal to the related share based compensation expense. 
The lessor deductions resulting from the exercise of nonqualified stock options increased the income tax provision by $5 thousand 
in 2023.

As  of  December  31,  2023  and  2022,  the  restricted  performance  shares  had  a  weighted-average  contractual  life  of  1.2  years, 
respectively. The compensation cost that was charged against income for the Company’s restricted performance shares granted was 
$250 thousand, $525 thousand and $610 thousand for the year ended December 31, 2023, 2022 and 2021, respectively. There were 
no stock appreciation rights or incentive stock options granted in the year ended December 31, 2023, 2022 and 2021. 

The Company repurchases shares of its common stock in the open market to optimize the Company’s use of equity capital and 
enhance shareholder value and with the intention of lessening the dilutive impact of issuing new shares under stock option plans, 
and other ongoing requirements. The Company repurchases and retires its common stock in accordance with Board of Directors 
approved  share  repurchase  programs.  The  repurchase  plan  approved  July  28,  2022  expired  September  1,  2023.  There  is  no 
replacement plan in place currently. 

The Company’s articles of incorporation 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, 2023, 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 
Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) require the Company to maintain a 
capital conservation buffer of 2.5% above the adequately capitalized risk-based capital ratios to avoid restrictions on dividends and 
equity  repurchases  and  other  payments  such  as  discretionary  bonuses  to  executive  officers.  The  net  unrealized  gain  or  loss  on 
available for sale securities is not included in computing regulatory capital. Management believes as of December 31, 2023 and 
December 31, 2022, 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 2023 and 2022, 
the  Bank  met  the  capital  requirements  to  be  well  capitalized  under  the  regulatory  framework  for  prompt  corrective  action. 
Management believes that there are no conditions or events that would change the institution’s category since December 31, 2023. 

The capital ratios for the Company and the Bank as of the dates indicated are presented in the table below. For Common Equity 
Tier 1 Capital, Tier 1 Capital and Total Capital, the required percentages for capital adequacy purposes include the 2.5% capital 
conservation buffer.

Note 10: Income Taxes 

Deferred  tax  assets  and  liabilities  are  recognized  for  future  tax  consequences  attributable  to  differences  between  the  amounts 
reported in the financial statements of existing assets and liabilities and their respective tax basis and operating loss and tax credit 
carryforwards. 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. Net deferred tax assets are included with other assets in the consolidated balance sheets. 

The components of the net deferred tax asset is as follows:    

Deferred tax asset

Allowance for credit losses
Securities available for sale
State franchise taxes
Deferred compensation
Purchased assets and assumed liabilities
Post-retirement benefits
Employee benefit accruals
VISA Class B shares
Accrued liabilities
Premises and equipment
Lease liability
Other

Total deferred tax asset

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. Net deferred tax 
assets are included with other assets in the consolidated balance sheets.

At December 31, 2023 and December 31, 2022, the Company had no uncertain tax positions related to previous years’ tax returns 
which were under examination. 

The Company classifies interest and penalties as a component of the provision for income taxes. For tax years 2023 and 2022, no 
interest or penalties were recognized as a component of the provision for income taxes. At December 31, 2023, the tax years ended 
December  31,  2022,  2021  and  2020  remain  subject  to  examination  by  the  Internal  Revenue  Service  and  the  tax  years  ended 
December 31, 2022, 2021, 2020 and 2019 remain subject to examination by the California Franchise Tax Board. 

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. Debt securities available for sale 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, loans 
individually evaluated for credit loss, certain loans held for investment, debt 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  FASB  Accounting  Standards  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 mutual funds, federal agency securities, mortgage-backed securities, corporate securities, 
commercial paper, collateralized loan obligations, municipal bonds and securities of U.S government entities and U.S. government 
sponsored entities.  

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 equity securities, debt securities available for 
sale and debt 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 most closely reflecting the market generally used as the fair value estimate. 
In addition, the Company evaluates debt securities for credit losses on a quarterly basis. 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.

Assets Recorded at Fair Value on a Nonrecurring Basis 

The Company may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance with 
GAAP. These adjustments to fair value usually result from the 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, 2023 and 
December 31, 2022, 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.

Disclosures about Fair Value of Financial Instruments 

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.  The carrying amounts in the following tables are recorded in the balance sheet under the indicated captions. 

The Company has not included assets and liabilities that are not financial instruments such as goodwill, long-term relationships 
with deposit, merchant processing and trust customers, other purchased intangibles, premises and equipment, deferred taxes, and

The majority of the Company’s standby letters of credit and other commitments to extend credit carry current market interest rates 
if converted to loans. No premium or discount was ascribed to these commitments because virtually all funding would be at current 
market rates. 

Note 12: 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. 
Certain agreements provide the Company the right to cancel or reduce its obligations to lend to customers. The portions that are not 
unconditionally  cancellable  by  the  Company  aggregated  $29,958  thousand  at  December  31,  2023  and  $31,889  thousand  at 
December  31,  2022.  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 $206,028 thousand at December 31, 2023 and $202,696 thousand at December 31, 2022. 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 $2,044 thousand 
at December 31, 2023 and $1,948 thousand at December 31, 2022. Commitments for commercial and similar letters of credit totaled 
$95 thousand at December 31, 2023 and $95 thousand at December 31, 2022. The Company had $1,000 thousand in outstanding 
full recourse guarantees to a third party credit card company at December 31, 2023 and $950 thousand at December 31, 2022.  At 
December  31,  2023,  the  Company  had  a  reserve  for  unfunded  commitments  of  $201  thousand  for  the  above-mentioned  loan 
commitments of $29,958 thousand that are not unconditionally cancellable by the Company. The Company’s reserve for unfunded 
commitments was $201 thousand at December 31, 2022. The reserve for unfunded commitments is 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.

Note 13: 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 $1,090 thousand in 2023, $1,030 thousand in 2022, and $1,028 thousand in 
2021. 

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 $873 thousand in 2023, $921 thousand in 2022, and $972 thousand in 2021. 

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, 2024. 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  year 
ended December 31 and the funded status of the post-retirement benefit plan as of December 31:

For the years ended December 31, 2023, 2022 and 2021, options to purchase 983 thousand, 787 thousand and 649 thousand shares 
of common stock, respectively, were outstanding but not included in the computation of diluted earnings per common share because 
the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

Shareholders and the Board of Directors of 
 Westamerica Bancorporation 
San Rafael, California 

Opinions on the Financial Statements and Internal Control over Financial Reporting 

We have audited the accompanying consolidated balance sheets of Westamerica Bancorporation (the "Company") as of December 
31, 2023 and 2022, the related consolidated statements of income, comprehensive income (loss), changes in shareholders’ equity, 
and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively referred 
to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 
2023, 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, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-
year period ended December 31, 2023 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, 2023, 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. 

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.  

Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was 
communicated  or  required  to  be  communicated  to  the  audit  committee  and  that:  (1)  relates  to  accounts  or  disclosures  that  are 
material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex  judgments.   The 
communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and 
we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the 
accounts or disclosures to which it relates. 

Allowance  for  Credit  Losses  on  Loans  –  Reasonable  and  Supportable  Forecasts  -  Refer  to  Notes  1  and  3  to  the  financial 
statements 

The allowance for credit losses on loans is an accounting estimate of expected credit losses over the estimated life of loans. ASC 
326, Financial Instruments – Credit Losses, requires a financial asset (or a group of financial assets), including the Company's loan 
portfolio, measured at amortized cost, to be presented at the net amount expected to be collected. The allowance for credit losses 
on loans as of December 31, 2023 was $16,867,000. 

The Company estimates the amount of expected losses over the life of its existing loan portfolio and establishes an allowance for 
credit losses. Loans that share common risk characteristics are segregated into pools based on those characteristics. Historical loss 
rates  are  determined  for  each  pool.  Historical  loss  rates  are  adjusted  for  estimated  losses  based  on  current  conditions  and 
management’s  reasonable  and  supportable  forecasts  of  economic  trends  over  a  forecast  horizon  of  up  to two years.  Significant 
management judgments are required in the development and application of reasonable and supportable forecasts. 

We identified the development and application of reasonable and supportable forecasts as a critical audit matter  because of the 
significant auditor judgment and audit effort to evaluate the subject judgments made by management, including the need to involve 
more experienced audit personnel. 

The primary procedures we performed to address this critical audit matter included:

ITEM 9. 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, 2023. 

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, 2023 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 
51 and 90, respectively.

contract,  instruction or  written plan  for the  purchase or  sale  of  Company  securities  that  was  intended to  satisfy the  affirmative
