PROXY STATEMENT 
March 11, 2019 
___________ 

GENERAL 

The Westamerica Board of Directors is soliciting proxies to be used at the 2019 Annual Meeting of Shareholders 
of Westamerica Bancorporation (the “Company”), which will be held at 10:00 a.m. Pacific Time, Thursday, April 
25,  2019,  or  at  any  adjournment  or  postponement  of  the  Annual  Meeting.  Proxies  are  solicited  to  give  all 
Shareholders  of  Record  (“registered  holder”)  an  opportunity  to  vote  on  matters  to  be  presented  at  the  Annual 
Meeting. In the following pages of this Proxy Statement, you will find information on matters to be voted at the 
Annual Meeting. 

Voting Information 

Internet Availability of Proxy Materials. We are providing proxy materials to our shareholders primarily via the 
internet, instead of mailing printed copies of those materials to each shareholder. By doing so, we save costs and 
reduce  the  environmental  impact  of  our  Annual  Meeting.  On  or  about  March  11,  2019,  we  mailed  a  Notice  of 
Internet Availability of Proxy Materials (“Notice”) to certain of our shareholders. The Notice contains instructions 
about how to access our proxy materials and vote online or vote by telephone. If you would like to receive a paper 
copy  of  our  proxy  materials,  please  follow  the  instructions  included  in  the  Notice.  If  you  previously  chose  to 
receive our proxy materials electronically, you will continue to receive access to these materials via email unless 
you elect otherwise. 

Proof of Ownership May Be Required for Attending Annual Meeting in Person. You are entitled to attend 
the Annual Meeting only if you are a shareholder as of the close of business on February 25, 2019, the record date, 
or hold a valid proxy for the meeting. In order to be admitted to the  Annual Meeting, the Company reserves the 
right to request proof of ownership of Westamerica Bancorporation common stock on the record date. This can be: 
  A brokerage statement or letter from a bank or broker indicating ownership on February 25, 2019;  
  The Notice of Internet Availability of Proxy Materials; 
  A printout of proxy distribution email (if you received your materials electronically);  
  A Proxy Card; 
  A voting instruction form; or 
  A legal proxy provided by your broker, bank or nominee.  

Any holder of a proxy from a shareholder must present the Proxy Card properly executed, and a copy of the proof 
of ownership. The Company reserves the right to ask shareholders and proxy holders to present a form of photo 
identification such as a driver’s license.   

Proxy  Card.  The  Board  has  designated  Catherine  MacMillan,  Ronald  A.  Nelson  and  Edward  B.  Sylvester  to 
serve as Proxies for the Annual Meeting. As Proxies, they will vote the shares represented by proxies at the Annual 
Meeting. If you sign, date and return your Proxy Card but do not specify how to vote your shares, the Proxies will 
vote FOR the election of all of the Director nominees, FOR approval of the advisory vote on the compensation of 
our named executive officers, FOR approval of the 2019 Omnibus Equity Incentive Plan, and FOR ratifying the 

1 

2019     WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
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 25, 2019. 

Quorum and Shares Outstanding. A quorum, which is a majority of the total shares outstanding as of the record 
date,  must  be  present  to  hold  the  Annual  Meeting.  A  quorum  is  calculated  based  on  the  number  of  shares 
represented  by  shareholders  attending  in  person  or  by  proxy.  On  February  25,  2019,  26,890,495  shares  of 
Westamerica  Bancorporation  common  stock  were  outstanding.  We  also  count  broker  non-votes,  which  we 
describe below, as shares present or represented at the Annual Meeting for the purpose of determining whether a 
quorum exists.  

Election of Director Nominees.  Each share is entitled to one vote, except in the election of Directors  where a 
shareholder  may  cumulate  votes  as  to  candidates  nominated  prior  to  voting,  but  only  when  a  shareholder  gives 
notice of intent to cumulate votes prior to the voting at the Annual Meeting. If any shareholder gives such notice, 
all  shareholders  may  cumulate  their  votes  for  nominees.  Under  cumulative  voting,  each  share  carries  as  many 
votes as the number of Directors to be elected, and the shareholder may cast all of such votes for a single nominee 
or  distribute  them  in  any  manner  among  as  many  nominees  as  desired.  This  Proxy  Statement  solicits  the 
discretionary  authority  to  cumulate  votes  and  allocate  them  in  the  Proxy  Holders’  discretion  if  any  shareholder 
requests cumulative voting. In the election of Directors, the 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. If you 
attend the Annual Meeting and have already voted, you may vote in person in order to rescind your previous vote.  

Vote Required; Effect of Abstentions and Broker Non-Votes. The shares of a shareholder whose ballot on any 
or all proposals is marked as “abstain” will be included in the number of shares present at the Annual Meeting to 
determine  whether  a  quorum  is  present.  If  you  are  the  beneficial  holder  of  shares  held  by  a  broker  or  other 
custodian, you may instruct your broker how to vote your shares through the voting instruction form included with 
this Proxy Statement. If you wish to vote the shares you own beneficially at the meeting, you must first request and 
obtain a legal proxy from your broker or other custodian. If you choose not to provide instructions or a legal proxy, 
your shares are referred to as “uninstructed shares.” Whether your broker or custodian has the discretion to vote 
these  shares  on  your  behalf  depends  on  the  ballot  item.  The  following  table  summarizes  the  votes  required  for 
passage of each proposal and the effect of abstentions and uninstructed shares held by brokers. 

Brokers  and  custodians  cannot  vote  uninstructed  shares  on  your  behalf  in  director  elections,  advisory  votes  on 
executive compensation or approval of equity incentive plans. For your vote to be counted, you must submit your 
voting instruction form to your broker or custodian.

Votes in favor of Proposals 2, 3 and 4 must also constitute a majority of the required quorum for the meeting.  If 
votes in favor are less than a majority of the required quorum, abstentions and non-votes will have the effect of a 
vote against the proposal. 

Other Matters. Approval of any other matter considered at the Annual Meeting will require the affirmative vote 
of a majority of the shares present or represented by proxy and voting at the Annual Meeting and a majority of the 
required quorum. 

How  You  Can  Vote.  Your  vote  is  very  important  and  we  hope  that  you  will  attend  the  Annual  Meeting. 
However, whether or not you plan to attend the Annual Meeting, please vote by proxy. 

Registered  Holders.  If  your  shares  are  registered  directly  in  your  name  with  the  Company’s  transfer  agent, 
Computershare Investor Services, LLC, you are considered a  registered holder of those shares. Please vote by 
proxy in accordance with the instructions on your Proxy Card, or the instruction you received by email.  

A registered holder can vote in one of the following four ways: 

  Via the Internet. Go to the website noted on your Proxy Card in order to vote via the internet. Internet 
voting is available 24 hours a day. We encourage you to vote via the internet, as it is the most cost-
effective way to vote. When voting via the internet, you do not need to return your Proxy Card. 

  By Telephone. Call the toll-free telephone number indicated on your Proxy Card and follow the voice 
prompt instructions to vote by telephone. Telephone voting is available 24 hours a day. When voting 
by telephone, you do not need to return your Proxy Card. 

  By Mail. Mark your Proxy Card, sign and date it, and return it in the enclosed postage-paid envelope. 
If  you  elected  to  electronically  access  the  Proxy  Statement  and  Annual  Report,  you  will  not  be 
receiving a Proxy Card and must vote via the internet or by telephone. 

  In  person.  You  may  vote  your  shares  at  the  Annual  Meeting  if  you  attend  in  person,  even  if  you 
previously  submitted  a  Proxy  Card  or  voted  via  internet  or  telephone.  Whether  or  not  you  plan  to 
attend the Annual Meeting, however, we strongly encourage you to vote your  shares by proxy before 
the meeting. 

We have been advised by counsel that these telephone and internet voting procedures comply with California 
law. 

Beneficial Shareholders. If your shares are held in a brokerage account in the name of your bank, broker,  or 
other  holder  of  record  (“beneficial  holder”  or  “street  name”),  you  are  not  a  registered  holder,  but  rather  are 
considered  a  beneficial  holder  of  those  shares.  Your  bank,  broker,  or  other  holder  of  record  will  send  you 
instructions on how to vote your shares. If you are a beneficial holder, you must obtain a legal proxy, executed 
in your favor, from the holder of record to be able to vote in person at the Annual Meeting. 

If  you  are  a  participant 

the  Westamerica  Bancorporation  Tax  Deferred 
in 
Voting  Deadlines. 
Savings/Retirement Plan (ESOP) your vote must be received by 11:59 p.m. Central Time, on April 22, 2019. 
All other shareholders voting by telephone or internet must vote by 12:01 a.m. Central Time, on April 25, 2019 
to ensure that their vote is counted.

Revocation  of  Proxy.  Registered  Holders  who  vote  by  proxy,  whether  by  telephone,  internet  or  mail,  may 
revoke that proxy at any time before it is voted at the Annual Meeting. You may do this by: (a) signing another 
Proxy  Card  with  a  later  date  and  delivering  it  to  us  prior  to  the  Annual  Meeting  or  sending  a  notice  of 
revocation to the Corporate Secretary of Westamerica at 1108 Fifth Avenue, San Rafael, CA 94901; (b) voting 
at a later time by telephone or on the internet prior to 12:01 a.m. Central Time, on April 25, 2019 (prior to 11:59 
p.m. Central Time, on April 22, 2019 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

discontinue householding and receive multiple Notices in future years. To receive an additional Annual Report 
or Proxy Statement this year, contact Shareholder Relations at 707-863-6992 or follow the instructions on the

Availability of Proxy Materials or paper copies of proxy materials, this Proxy Statement and the  2018 Annual

2019     WESTAMERICA BANCORPORATION PROXYTHE BOARD OF DIRECTORS RECOMMENDS ELECTION OF ALL NOMINEES 

Board of Directors and Committees 

Director Independence and Leadership Structure  
The  Board  of  Directors  has  considered  whether  any  relationships  or  transactions  related  to  a  Director  were 
inconsistent  with  a  Director’s independence.  Based on  this  review,  the  Board  has  determined  that E.  Allen,  L.E. 
Bartolini, E.J. Bowler, P.D. Lynch, C.C. MacMillan, R.A. Nelson, and E.B. Sylvester are “independent” Directors 
as defined in NASDAQ rules. 

Our Board has carefully considered the critical issue of Board leadership. In the context of risk management, the 
leadership  of  each  Board  committee  primarily  responsible  for  risk  management  is  vested  in  an  independent 
committee  chair.  With  regard  to  the  leadership  of  the  meetings  of  the  full  Board,  our  Board  of  Directors  has 
carefully  evaluated  whether  the  positions  of  Chairman  and  CEO  should  be  separate  or  combined.  Our  Board 
believes that the most effective leadership structure for the Company at this time is to combine the responsibilities of 
the Chairman and CEO, a structure that has been successful since 1989. The combined positions avoid a duplication 
of  efforts, enable  decisive  leadership,  ensure  a clear  accountability  for  the  performance  of  the  Company,  a  more 
rapid implementation of decisions, and a consistent vision. Given the size of our employee base and our level of 
assets relative to larger, more complex banking structures, our Company is particularly well suited to combine the 
Chairman and CEO functions. Furthermore, our named executive officers have an average tenure of 21 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  every  non-management  director  sits  on  one  or  more  of  these  Committees.  All  non-management 
directors meet at least four times a year outside the presence of the Chairman and CEO. The Board completes an 
annual board evaluation that is discussed by the Nominating Committee and presented to the full Board. 

Although the Board believes that it  is more effective to have one person serve as the  Chairman and CEO at this 
time, it also recognizes the importance of strong independent leadership on the Board, accordingly, the Board has 
established  a  strong,  independent  Lead  Director,  Mr.  Sylvester,  who  must  serve  at  least  one  year  and  has  the 
following clearly delineated and comprehensive duties: 

  Presides at all meetings of the Board at which the Chairman is not present, including executive sessions of 

the independent Directors; 

  Serves as liaison between the Chairman and the independent Directors; 
  Approves information sent to the Board; 
  Approves meeting agendas for the Board; 
  Approves meeting schedules to assure that there is sufficient time for discussion of all agenda items; 
  Has the authority to call meetings of the independent Directors; and 
  If  requested  by  major  shareholders,  ensures  that  he  or  she  is  available  for  consultation  and  direct 

communication. 

The  Board  does  not  believe  that  the  fact  an  independent  Lead  Director  does  not  preside  over  the  normal  Board 
meeting business sessions limits the ability of the Board to have open exchanges of views, or to address any issues 
the Board chooses, independently of the Chairman.  

The Board of Directors of the Company also serve as the Board of Directors of Westamerica Bank, and as such are 

10 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
 
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  2018.  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 with the exception of 
Mr. Lynch who attended 67% of the aggregate of such meetings. Each individual who served on the Board of the 
Company on the date of the 2018 Annual Meeting of Shareholders attended the meeting.

Executive Committee 

Functions:  The  Board  delegates  to  the  Executive  Committee  all  powers  and  authority  of  the  Board  in  the 
management  of  the  business  affairs  of  the  Company  between  board  meetings,  which  the  Board  is  allowed  to 
delegate under California law.  

Audit Committee 

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

  an understanding of generally accepted accounting principles and financial statements;  
 

the  ability  to  assess  the  general  application  of  such  principles  in  connection  with  the  accounting  for 
estimates, accruals and reserves;  

  experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level 
of complexity of accounting issues that are generally comparable to the breadth and complexity of issues 
that can reasonably be expected to be raised by the Company’s financial statements, or experience actively 
supervising one or more persons engaged in such activities; 
  an understanding of internal control over financial reporting; and  
  an understanding of Audit Committee functions. 

Designation  of  a  person  as  an  Audit  Committee  financial  expert  does  not  result  in  the  person  being  deemed  an 
expert for any purpose, including under Section 11 of the Securities Act of 1933. The designation does not impose 
on the person any duties, obligations or liability greater than those imposed on any other Audit Committee member 
or  any  other  Director  and  does  not  affect  the  duties,  obligations  or  liability  of  any  other  member  of  the  Audit 
Committee or Board of Directors. 

Functions:  The  Audit  Committee  provides  independent,  objective  oversight  of  the  integrity  of  the  Company’s 
financial  statements,  the  Company’s  compliance  with  legal  and  regulatory  requirements,  the  independence  and 
performance  of  the  Company’s  independent  auditor  as  it  performs  audit,  review  or  attest  services,  and  the 
Company’s internal audit and control function. It selects and retains the independent registered public accounting 
firm, and reviews the plan and the results of the auditing engagement. It acts pursuant to a written charter that was 
reaffirmed by the Board of Directors in January 2018 and attached as Exhibit A to the Proxy Statement for the 2018 
Annual Meeting of Shareholders. 

Employee Benefits and Compensation Committee 

The Employee Benefits and Compensation Committee of the Board of Directors (the “Compensation Committee”) 
is comprised solely of Directors who are not current or former employees of Westamerica or any of its affiliates. 
They are independent as defined by NASDAQ rules. 

Functions: The Compensation Committee administers Westamerica Bancorporation’s 2012 Amended and Restated 
Stock  Option  Plan  of  1995,  Tax  Deferred  Savings  and  Retirement  Plan,  Deferred  Profit  Sharing  Plan,  Deferred 
Compensation  Plan,  and  the  Westamerica  Bancorporation  Deferral  Plan.  It  administers  the  Company’s 
compensation  programs  and  reviews  and  reports  to  the  Board  the  compensation  level  for  executive  officers, 
including  the  CEO,  of  the  Company  and  its  subsidiaries  and  determines  that  compensation  plans  are  balanced 
between  financial  results  and  prudent  risk  taking.  The  Compensation  Committee  determines  annual  corporate 
performance  objectives  for  equity  compensation  and  cash  bonuses  and  their  related  corporate,  divisional  and 

12 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
individual goals. Based on the CEO’s assessment of the extent to which each executive officer met those objectives 
and  goals,  the  Committee  determines  each  executive  officer’s  annual  equity  compensation  and  cash  bonus.  The 
Compensation Committee also establishes the individual goals and targets for the CEO. All compensation approved 
by  the  Compensation  Committee  is  reported  to  the  full  Board  of  Directors.  The  role  of  the  Compensation 
Committee is described in greater detail under the section entitled “Compensation Discussion and Analysis.” 

The  Compensation  Committee  is  governed  by  a  written  charter  as  required by  NASDAQ  rules. The  charter  was 
reaffirmed by the Board of Directors in January 2017 and attached as Exhibit B to the Proxy Statement for the 2017 
Annual Meeting of Shareholders. The Compensation Committee has the authority to seek assistance from officers 
and employees of the Company as well as external legal, accounting and other advisors. It has not retained outside 
consultants for compensation advice, but can request assistance on an as-needed basis. It does not delegate authority 
to anyone outside of the Compensation Committee. The  Payroll and Employee Benefits Department supports the 
Compensation Committee by fulfilling certain administrative duties regarding the compensation programs. 

Nominating Committee 

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

Functions: The Nominating Committee screens and recommends qualified candidates for Board membership. This 
Committee  recommends  a  slate  of  nominees  for  each  Annual  Meeting.  As  part  of  that  process,  it  evaluates  and 
considers all candidates submitted by shareholders in accordance with the Company’s Bylaws, and considers each 
existing  Board  member’s  contributions.  The  Committee  applies  the  same  evaluation  standards  whether  the 
candidate was recommended by a shareholder or the Board. The Nominating Committee is governed by a written 
charter, which was reaffirmed by the Board of Directors in January 2019 and is attached as Exhibit A to the Proxy 
Statement for this 2019 Annual Meeting of Shareholders. 

While the Board does not have a formal diversity policy, it broadly defines diversity to encompass a diverse range 
of skills and expertise sufficient to provide prudent guidance to the Company. In addition to the qualifications and 
characteristics  described  below,  it  considers  whether  the  potential  Director  assists  in  achieving  a  mix  of  Board 
members that represents a diversity of background, perspective, and experience. Our Board includes Directors with 
experience  in  public  corporations  and  non-profit  organizations,  as  well  as  entrepreneurial  individuals  who  have 
successfully  run  their  own  private  enterprise.  Our  Board  also  has  a  broad  set  of  skills  necessary  for  providing 
oversight to a financial institution, which includes proven leadership, and expertise in capital management, finance, 
accounting, regulatory affairs, and investment management. 

Nominating  Directors.  The  Nominating  Committee  will  consider  shareholder  nominations  submitted  in 
accordance  with  Section  2.14  of  the  Bylaws  of  the  Company.  That  section  requires,  among  other  things,  that 
nominations be submitted in writing and must be received by the Corporate Secretary at least 45 days before the 
anniversary of the date on which the Company first mailed its proxy materials for the prior year’s Annual Meeting 
of  Shareholders.  If  the  date  for  the  current  year’s  Annual  Meeting  changes  more  than  30  days  from  the  date  on 
which the prior year’s meeting was held, the Company must receive notice with a reasonable amount of time before 
the Company mails its proxy materials for the current year. 

Nominations must include the following information: 

  The principal occupation of the nominee; 
  The total number of shares of capital stock of the Company that the shareholder expects will be voted for 

the nominee; 

  The name and address of the nominating shareholder; and 

13

 The number of shares of capital stock of the Company owned by the nominating shareholder.

The  Committee has  specified  the  following  minimum  qualifications  it  believes  must  be  met  by  a  nominee  for  a 
position on the Board: 

 Appropriate personal and professional attributes to meet the Company’s needs;
 Highest ethical standards and absolute personal integrity;
 Physical and mental ability to contribute effectively as a Director;
 Willingness and ability to participate actively in Board activities and deliberations;

 Willingness to devote the time necessary to function effectively as a Board member;
 Possess independence necessary to make unbiased evaluation of Management performance;
 Be free of any conflict of interest that would violate applicable law or regulation or interfere with ability to

perform duties;

 Broad experience, wisdom, vision and integrity;
 Understanding of the Company’s business environment; and
 Significant business experience relevant to the operations of the Company.

(1) Non-employee Directors did not receive options or stock awards. During 2018, non-employee Directors of the Company each received an 
annual  retainer  of  $22,000.  Each  non-employee  Director  received  $1,200  for  each  meeting  of  the  Board  attended  and  $600  for  each 
Committee meeting attended. The Chairman of each Committee received an additional $250 for each Committee meeting attended. All non-
employee Directors are reimbursed for expenses incurred in attending Board and Committee meetings. The Chairman of the Board, David 
L. Payne, is compensated as an employee and did not receive any compensation as a Director.

(2) The  Deferred  Compensation  Plan  allows  non-employee  Directors  to  defer  some  or  all  of  their  Director  compensation  with  interest 
earnings credited on deferred compensation accounts. The amount shown is the interest on nonqualified deferred compensation that exceeds

120% of the long-term Applicable Federal Rate, with compounding, on all cash compensation deferred in 2018 and in previous years.

Compensation Discussion and Analysis  

The executive compensation practices described below have been followed consistently for twenty-five years. At 
each Annual Meeting of Shareholders since 2010, a majority of our shareholders approved an advisory proposal on 
the Company’s executive compensation. 

(1) Mr. Hansen retired from the position of Manager of the Operations and Systems Administration of Community Banker Services 
Corporation effective December 31, 2018.

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. 

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 

16 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
within the industry, trade balances, the changing values of real estate, currencies, commodities and other assets, and 
other factors. 

Management policies and practices the Board considers in establishing corporate performance objectives include, 
but are not limited to, management of the Company’s balance sheet and product pricing in a  manner  which  will 
benefit the long-term financial  interests of shareholders, the type and variety of financial products offered by the 
Company,  adherence  to  internal  controls,  management  of  the  credit  risk  of  the  Company’s  loan  and  investment 
portfolios,  the  results  of  internal,  regulatory  and  external  audits,  service  quality  delivered  to  the  Company’s 
customers, service quality of “back office” support departments provided to those offices and departments directly 
delivering  products  and  services  to  the  Company’s  customers,  maintenance  of  operating  policies  and  procedures 
which  remain  appropriate  for  risk  management  in  a  dynamic  environment,  timely  and  efficient  integration  of 
acquired companies, operational efficiencies, and capital management practices. 

Restricted performance shares (“RPS”) represent awards of Westamerica Bancorporation’s common stock subject 
to achievement of performance objectives established by the  Compensation Committee. The 2012 Amended and 
Restated Stock Option Plan of 1995 (the “2012 Amended Plan”), which was originally approved by shareholders in 
1995, and amended with shareholder approval in 2003 and again in 2012, defines the performance factors the Board 
must use in administering RPS grants as one or more of the following: earnings, diluted earnings per share, revenue 
and revenue per diluted share, expenses, share price, return on equity, return on equity relative to the average return 
on equity for similarly sized institutions, return on assets, return on assets relative to the average return on assets for 
similarly sized institutions, efficiency ratio (operating expenses divided by operating revenues), net loan losses as a 
percentage of average loans outstanding, nonperforming assets, and nonperforming assets as a percentage of total 
assets.  

In  addition  to  establishing  corporate  performance  objectives,  the  Compensation  Committee  also  establishes 
individual  goals  for  the  CEO.  In  regard  to  the  other  executives  named  in  the  accompanying  tables,  the  CEO 
recommends divisional and individual performance objectives to the Compensation Committee, which considers, 
discusses, adjusts as necessary, and adopts such performance objectives. 

Upon the closure of each calendar year, the Compensation Committee reviews corporate, divisional, and individual 
performance against the performance objectives for the year just completed. After thorough review and deliberation, 
the Compensation Committee  determines the recommended amount of individual non-equity cash incentives and 
stock-based  incentive  awards.  The  Compensation  Committee  reports  such  incentives  to  the  Board  of  Directors. 
Meetings  of  the  Compensation  Committee  and  Board  of  Directors  routinely  occur  in  January,  immediately 
following the closure of the calendar year for which performance is measured for incentive compensation purposes. 

Stock Grants 

Long-term  stock  grants  may  only  be  awarded  under  shareholder  approved  stock-based  incentive  compensation 
plans.  The  Company’s  Proxy  Statement  dated  March  12,  2012,  as  filed  with  the  SEC  on  March  13,  2012, 
summarizes the 2012 Amended Plan’s changes from the predecessor plan. Such changes included: 

  reducing the issuable shares to 1,500,000 (plus shares that become available if awards under prior plans 

expire unexercised or are cancelled, forfeited or terminated before being exercised); 

  any additional authorization of shares available for issuance must be approved by shareholders; and 
  establishing a plan expiration date of April 26, 2022 after which shareholder approval is again required to 

extend the term or approve a new stock option plan. 

17 

2019     WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
The 2012 Amended Plan allows four types of stock-based compensation awards: 

Incentive  Stock  Options  (“ISO”)  allow  the  optionee  to  buy  a  certain  number  of  shares  of  Westamerica 
Bancorporation  common  stock  at  a  fixed  price,  which  is  established  on  the  date  of  the  option  grant.  ISOs  are 
intended to meet the requirements of Section 422 of the Internal Revenue Code which provide advantages if certain 
conditions are met. If the optionee holds the acquired stock for the designated holding period, the optionee defers the 
timing  of  recognizing  taxable  income  related  to  exercising  the  ISO.  If  the  optionee  complies  with  the  ISO 
requirements, the Company does not receive a corporate tax deduction related to the shares issued. 

Nonqualified  Stock  Options  (“NQSO”)  also  give  the  optionee  the  option  to  buy  a  certain  number  of  shares  of 
Westamerica Bancorporation common stock at a fixed price, which is established on the date of grant. Unlike ISOs, 
NQSOs do not allow deferral of taxable income for the optionee. At the time NQSOs are exercised, the optionee 
incurs  taxable  income  equal  to  the  spread  between  the  exercise  price  and  the  market  price  of  the  stock,  and  the 
Company receives a corporate tax deduction in the same amount. 

Stock Appreciation Rights (“SAR”)  provide  the  holder  a  cash  payment  equal  to  the  difference  between  the  fair 
market value of the Westamerica Bancorporation’s common stock on the date the SAR is surrendered and the fair 
market  value  of  the  Company’s  common  stock  on  the  date  the  SAR  was  granted.  The  optionee  incurs  taxable 
income at the time the SAR is settled and the Company receives a corporate tax deduction in the same amount. 

Restricted Performance Share Grants, as noted above, are awards of the Westamerica Bancorporation’s common 
stock that are subject to the achievement of performance objectives. Award recipients receive shares at the end of 
the  performance  measurement  period  only  if  performance  objectives  are  achieved.  The  award  recipient  incurs 
taxable income at the time any RPS vests and the Company receives a corporate tax deduction in the same amount. 

Determination of Awards to Grant 

In determining which type of stock-based compensation awards to grant, the Compensation Committee considers 
the attributes of each form of incentive. Examples include the ability to motivate management to make decisions 
based on the long-term interests of shareholders, the desire to compensate with shares rather than cash, and the tax 
consequences  of  each  type  of  award.  The  Compensation  Committee  retains  the  latitude  to  utilize  all  forms  of 
incentives  provided  under  the  2012  Amended  Plan.  In  the  current  and  preceding  years,  the  Compensation 
Committee has utilized NQSO and RPS based on the motivational aspects of stock price appreciation, the settlement 
in shares rather than cash, and the preservation of tax deductions for the Company. As of February 25, 2019, the 
Company had no ISO or SAR awards outstanding. 

Determination of Option Exercise Price 

The 2012  Amended  Plan  also  requires  the  exercise price  of  each  NQSO  or  ISO  to  be  no  less  than  one  hundred 
percent (100%) of the fair market value of the Company’s common stock on the date of grant. The 2012 Amended 
Plan does not allow re-pricing stock options for poor stock price performance. 

Stock-based compensation awards are submitted by the Compensation Committee to the full Board of Directors for 
review. As described above, these meetings have routinely occurred in January immediately following the closure of 
the  calendar  year  for  which  performance  is  measured  for  incentive  compensation  purposes.  The  Compensation 
Committee meeting has routinely been held during the same week as the related Board of Directors meeting. These 
January meetings follow by no more than ten business days the Company’s public disclosure of its financial results 
for  the  preceding  year.  As  a  result,  stock  option  grants  are  awarded,  and  the  exercise  price  of  such  grants  are 
determined  at  a  time  when  the  Company  has  broadly  disseminated  its  financial  condition  and  current  operating 

18 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
 
results to the public. The Company’s outstanding stock option grants are dated, and related stock option exercise 
prices are determined, on the January date the Compensation Committee meets to approve such grants. 

Long-Term Incentive Attributes 

The Board  of  Directors  has  designated  the  Compensation  Committee  as  the  administrator of  the  2012  Amended 
Plan.  The  Compensation  Committee  reports  to  the  Board  the  terms  and  conditions  of  stock  option  awards.  In 
carrying  out  this  responsibility,  the  Compensation  Committee  designs  such  awards  as  long-term  incentives.  The 
terms and conditions of currently outstanding awards include: 

  NQSO grants vest one-third (1/3) on each anniversary of the grant date. As such, NQSO grants become 
fully vested over a three-year period. NQSO grants expire on the tenth anniversary of the grant date. The 
Company  does  not  pay  dividends  on  shares  underlying  NQSO  grants  until  the  optionee  exercises  the 
option and the shares are outstanding on a dividend record date. 

  RPS  awards  vest  three  years  following  the  grant  date,  only  if  corporate  performance  objectives  are 
achieved over  the  three-year  period. The  Company  does  not  pay  dividends on  RPS  shares  until  vesting 
occurs and shares awarded become outstanding on a dividend record date. 

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 also serves as President and  CEO  with 
responsibilities  including  daily  management  of  internal  operations.  Mr. Payne’s  total  compensation  reflects  these 
broad  responsibilities.  Consistent  with  the  overall  compensation  philosophy  for  senior  executives,  Mr.  Payne’s 
compensation has a greater amount of pay at risk through incentives than through base salary. Since Mr. Payne is 
compensated as an executive, he is not eligible to receive compensation as a Director. 

As  noted  on  page  30  of  the  Proxy  under  the  Pension  Benefits  Table,  during  1997  the  Company  entered  into  a 
nonqualified pension agreement (“Pension Agreement”) with Mr. Payne in consideration of Mr. Payne’s agreement 
that RPS granted in 1995, 1996 and 1997 would be cancelled.(1) In entering the Pension Agreement, the Board of 
Directors considered the following: 

  Mr. Payne had a significant beneficial interest in Westamerica Bancorporation common stock, which was 
more than adequate to continue to provide motivation for Mr. Payne to continue managing the Company in 
the best interests of shareholders. 

  In  1997,  the  Company  had  consummated  its  largest  acquisition,  with  significant  total  asset  growth  of 
approximately  51  percent.  One  of  the  Board’s  objectives  was  to  provide  a  compensation  mechanism 
providing  retention  features  for  Mr.  Payne.  Retention  of  Mr.  Payne  as  President  and  CEO  was  desired 
following the Company’s significant growth. The RPS shares surrendered for the Pension Agreement were 
scheduled to vest on dates in 1998, 1999 and 2000, while the Pension Agreement was not fully vested until 
December 31, 2002. Additionally, the 20-year certain pension provided under the Pension Agreement was 
to commence upon Mr. Payne’s attainment of age 55. Mr. Payne was age 42 at the time of entering the 
Pension Agreement. 

Compensation Awarded to Named Executive Officers 

Base salaries for participants in the executive compensation program are generally limited to foster an environment 
where incentive compensation motivates and rewards corporate, divisional, and individual performance. As such, 
base pay increases are generally infrequent and limited to “control points” assigned to each position. The non-equity 
cash incentive formula has the following components:  

(1)The value of the surrendered RPS shares and the Pension Agreement were considered equivalent based on actuarial assumptions.

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  2018

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 2018 corporate performance goals related to 
current  year  “profitability”  included  return  on  equity,  return  on  assets  and  diluted  earnings  per  share.  The 
performance  goals  designed  to  maintain  the  long-term  stability  of  the  Company  include  “quality”  and  “control” 
components. The “quality” measures include loan portfolio quality measures (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  non-interest 
expense to revenues (efficiency ratio), the level of non-interest expenses, and internal audit results. By maintaining 
both  current  year  “profitability”  goals  and  longer-term  “quality”  and  “control”  goals,  Management  has  a 
disincentive to maximize current earnings at the expense of longer-term results.  

For 2018, the Compensation Committee expected stable economic growth with rising interest rates and a flattening 
of the yield curve. The Committee reserved the ability to exercise a certain degree of judgment in adjusting target 
goals based on the resulting operating environment. 

The Compensation Committee determined the 2018 operating environment was generally characterized as follows: 

  Growth in the United States’ economy increased slightly from the prior year; 
  Inflation remained below targets established by the Federal Open Market Committee in spite of improving

  The Federal Open Market Committee increased the federal funds rate on four occasions resulting in rising 
short-term interest rates; however, intermediate term interest rates did rise by the same magnitude resulting 
in a meaningful decline in the slope of the yield curve; 

  Throughout much of 2018, competitive interest rates on loans remained below the yields required for the 
Company  to  deliver  satisfactory  financial  results  throughout  a  full  business  cycle,  although  such 
competitive interest rates were more profitable toward the end of the year;

which could be sustained by prevailing economic conditions; and 

  Regulations  imposed  on  banks  continued  to  pressure  compliance  costs,  revenue  opportunities,  and 

increased operational risks. 

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

  Management maintained discipline in pricing loans and deposits for long-term financial results; 
  Management  consistently  maintained  conservative  corporate  bond  and  loan  underwriting  practices  to 

appropriately manage the Company’s exposure to credit risk; 

  Management  avoided  higher-yielding  longer-dated  investment  securities,  maintaining  an  appropriately 

short duration bond portfolio to provide asset re-pricing opportunities as interest rates rise;  

  Management enhanced the value of the Company’s deposit base through growth in checking and savings 

deposits and a reduction in time deposits; 

  Management contained operating costs to deliver revenue improvement to pre-tax income; 
  Management maintained high levels of customer service; and 
  Management prudently managed capital enabling the Company to continue delivering increasing annual 

levels of dividends per share and position the Company for growth opportunities.  

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

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

As described above, divisional and individual goals are used in conjunction  with corporate performance goals to 
determine cash bonus awards.

level was 118%. 

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

RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved 
over  the  three-year  period.  In  January  2019,  the  Compensation  Committee  evaluated  whether  the  three  year 
corporate performance objectives were met for RPS awards granted in January 2016. The performance objectives 
for the RPS granted in January 2016 included: 

(1) Mr. Hansen retired from the position of Manager of the Operations and Systems Administration of Community Banker Services 
Corporation effective December 31, 2018. 
(2) Mr. Hansen retired from the position of Manager of the Operations and Systems Administration of Community Banker Services 
Corporation effective December 31, 2018. As such, no NQSO were granted to Mr. Hansen. 
(3) Mr. Hansen retired from the position of Manager of the Operations and Systems Administration of Community Banker Services

  3 year average of annual return on average total assets (ROA); 
  3  year  average  of  annual  return  on  average  shareholders’  equity  relative  to  industry  average  ROE 

(ROE differential); 

  Ending originated non-performing assets to total originated assets (NPA); and 
  Efficiency ratio over three years. 

The RPS would vest if any one of the following performance results were achieved: 

  4 of 5 objectives reaching “threshold” performance level; 
  3 of 5 objectives reaching “target” performance level; or 
  2 of 5 objectives reaching “outstanding” performance level.

With  five  of  the  goals  achieving  the  “threshold”  performance  level  or  better,  the  Compensation  Committee 
determined the RPS shares awarded in 2016 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. 

  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. 

25 

2019     WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 exceed the equivalent of one  times annual  salary.  Messrs. Payne,  Thorson and  Rizzardi are eligible for 
one year’s salary under the plan. Mr. Ensinger was eligible for the equivalent of 30-weeks salary under the plan as 
of  December  31,  2018.  Mr.  Hansen  retired  from  the  Company’s  subsidiary  Community  Banker  Services 
Corporation as of December 31, 2018 and is no longer eligible for benefits under the plan, 

Other  

Internal  Revenue  Code  (“IRC”)  Section  162(m)  places  a  limit  on  the  amount  of  compensation  that  may  be 
deducted by the Company in any year with respect to certain of the Company’s highest-paid executives. Prior to 
enactment of the Tax Cuts and Jobs Act of 2017 (the “Act”), certain “performance-based compensation”  was 
not  counted  toward  this  limit.  The  Act  eliminated  the  “performance-based  compensation”  exemption  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 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, 2018.

Company or any of its subsidiaries  with a  value in excess  of $120,000. None of the executive officers of the 
Company has served on the Board of Directors or on the Compensation Committee of any other entity, where 
one  of  that  entity’s  executive  officers  served  either  on  the  Board  of  Directors  or  on  the  Compensation 
Committee of the Company.

(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

Pay Ratio Disclosure 

In August 2015 pursuant to a mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the 
Securities  and  Exchange  Commission  adopted  a  rule  requiring  annual  disclosure  of  the  ratio  of  the  median 
employee’s  annual  total  compensation  to  the  total  annual  compensation  of  the  principal  executive  officer

In  determining  the  median  employee  total  annual  compensation,  the  Company  prepared  a  census  of  all 
employees as of December 31, 2018, except the PEO, with compensation annualized for those employees hired 
in 2018. 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.

Non-Qualified Pension Agreement

$4,559,102

$511,950

During 1997, the Company entered into a nonqualified pension agreement with Mr. Payne in consideration of Mr. 
Payne’s  agreement  that  RPS  awards  granted  in  1995,  1996  and  1997  would  be  cancelled.  In  January  2000,  the 
Compensation Committee, based on the Company’s achievement of certain performance goals which had first been 
established for Mr. Payne’s 1995, 1996 and 1997 RPS awards, determined Mr. Payne’s annual pension would be 
$511,950. The pension commenced in 2010 and will be paid to Mr. Payne for 20 years.  

The discount rate used to determine the present value is 3.90%. The obligation is an unfunded general obligation 
of the Company.

compensation.    The  amounts  included  in  the  Summary  Compensation  Table  for  Fiscal  Year  2018  on  page  27  are  as  follows:    Messrs. 
Thorson - $22,351; Hansen - $14,371; Ensinger - $130. 
(3) Includes dividends paid on deferred RPS shares.

Hansen - $2,167,268; Ensinger - $11,684.  
(5)  Mr.  Hansen  retired  from  the  position  of  Manager  of  the  Operations  and  Systems  Administration  of  Community  Banker  Services

Under  the  Westamerica  Bancorporation  and  Subsidiaries  Deferred  Compensation  Plan  (the  “Deferred 
Compensation  Plan”),  Directors  and  Officers  may  defer  up  to  100%  of  their  Director’s  compensation,  salary 
and/or non-equity incentive compensation (cash bonus) into a non-qualified, unfunded deferred compensation 
program. The interest rate credited during 2018 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.

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
 
 
 
 
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 1 immediately following termination as elected by the 
participant at the time of deferral. If the participant is one of the named executive officers, benefit distributions 
that  are  made  upon  termination  of  employment  may  not  start  earlier  than  six  months  after  the  date  of 
termination. 

Potential Payments Upon Termination or Change in Control 

Payments  to  be  made  to  the  named  executive  officers  in  the  event  of  termination  of  employment  or  change  in 
control are described below.  

Termination 

Vested  NQSOs  may  be  exercised  within  90 days  of  termination  and  within  one  year  of  death  or  disability.  RPS 
shares  vest  if  the  Compensation  Committee  determines  performance  goals  are  met.  Terminated  employees  will 
receive vested RPS shares if the settlement date of the RPS grant occurs within 90 days of termination. Employees 
separating from service due to death, disability or retirement are eligible to receive a pro rata portion of granted RPS 
shares  if  the  Compensation  Committee  determines  that  the  performance  goals  are  likely  to  be  met  for  the  grant 
period. The pro rata basis is determined by the number of full years of the vesting period completed before date of 
death, disability or retirement.   

Deferred compensation account balances are distributed on January 1 following termination, or a specific date 
at least five years from the date of deferral in the form of annual payments over four years. Payment may also 
be made in a lump sum or in annual payments for five or 10 years as elected by the participant at the time of 
deferral.  If  the  participant  is  one  of  the  named  executive  officers,  benefit  distributions  that  are  made  upon 
termination of employment may not start earlier than six months after the date of termination.  

Change in Control 

A  change  in  control  is  defined  under  the  2012  Amended  Plan  as  shareholder  approval  of  a  dissolution  or 
liquidation  of  the  Company  or  a  sale  of  substantially  all  of  the  Company’s  assets  to  another  company,  or  a 
tender offer for 5% or more of the Company’s outstanding common stock or a merger in which the Company’s 
shareholders before the merger hold less than 50% of the voting power of the surviving company after the merger. 

In the event of a change  in control,  unvested NQSOs and  RPS shares immediately  vest. The value  of in-the-
money  options  and  RPS  shares  subject  to  accelerated  vesting  for  each  of  the  named  executive  officers  is  as 
follows:  Messrs.  Payne:  $0;  Thorson:  $516,037;  Hansen(1):  $464,592;    Rizzardi(2):  $418,277;  and  Ensinger: 
$339,569.  The  value  is  computed  by  multiplying  the  difference  between  the  market  value  on  December  31, 
2018, the last business day of  2018, and the exercise price of each option by the number of shares subject to 
accelerated vesting. 

Under  the  Company’s  Severance  Payment  Plan,  executive  officers  receive  six  week’s  pay  for  every  year  or 
partial year of service up to one year’s base salary (see Summary Compensation Table for Fiscal Year 2018 for 

(1) Mr. Hansen retired from the position of Manager of the Operations and Systems Administration of Community Banker Services

annual base salary for all named executive officers).  Messrs. Payne, Thorson and Rizzardi are eligible for one 
year’s  salary  under  the  plan.  Mr.  Ensinger  was  eligible  for  the  equivalent  of  30-weeks  pay  under  the  plan  as  of 
December 31, 2018. Mr. Hansen retired from the Company’s subsidiary Community Banker Services Corporation 
as of December 31, 2018 and is no longer eligible for benefits 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.

In  accordance  with  the  Audit  Committee  Charter,  the  Audit  Committee  is  responsible  for  reviewing  and 
approving or disapproving all related party transactions required to be disclosed by Item 404 of Regulation S-K for 
potential  conflicts  of  interest.  The  Company  is  also  required  by  NASDAQ  Rule  5250(b)(3)  to  disclose  all 
agreements and arrangements between any director or nominee for director, and any person or entity other than the 
Company  (the  “Third  Party”),  relating  to  compensation  or  other  payment  in  connection  with  such  person’s 
candidacy  or  service  as  a  director  of  the  Company.    The  Company  is  not  aware  of  any  such  agreements.  
Additionally,  the  Company’s  Code  of  Conduct  and  Ethics  provides  rules  that  restrict  transactions  with  affiliated 
persons. 

Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries 
of  the  Company  in  the  ordinary  course  of  business.  With  the  exception  of  the  Company’s  Employee  Loan 
Program, all outstanding loans and commitments included in such transactions were made on substantially the 
same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions 
with other persons not related to the Company, did not involve more than a normal risk of collectability, and did 
not present other favorable features. As part of the Employee Loan Program, all employees, including executive 
officers, are eligible to receive mortgage loans with interest rates one percent (1%) below Westamerica Bank’s 
prevailing interest rate at the time of loan origination. Westamerica Bank makes all loans to executive officers 
under  the  Employee  Loan  Program  in  compliance  with  the  applicable  restrictions  of  Section  22(h)  of  the 
Federal  Reserve  Act.  Messrs.  Payne  and  Thorson  have  mortgage  loans  through  this  Program.  The  largest 
aggregate  amount  of  principal  during  2018  was  $367,495  and  $254,253,  respectively.  The  principal  amount 
outstanding  at  December  31,  2018  was  $347,727  and  $229,015,  respectively.  The  amount  of  principal  paid 
during 2018 was $19,768 and $25,238, respectively. The amount of interest paid during 2018 was $12,807 and 
$7,629, respectively. The rate of interest payable on the loans is 4.00% and 4.375%, respectively.  

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

Background 

The 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires that 
shareholders  cast  a  non-binding  advisory  vote  on  the  executive  compensation  paid  to  the  executive  officers 
listed  in  the  Summary  Compensation  Table  (a  so-called  “say  on  pay”  vote)  as  well  as  an  advisory  vote  with 
respect  to  whether  future  say  on  pay  votes  will  be  held  every  one,  two  or  three  years.  The  result  of  the 
shareholder  vote  on  the  proposal  to  determine  the  frequency  of  future  say  on  pay  proposals  was  that 
shareholders should review executive compensation annually. Therefore, Proposal 2 requests that shareholders 
again approve the compensation paid to our named executive officers. Last  year 99% of the shares voting on 
this  proposal  voted  to  support  our  Corporation’s  executive  compensation  strategy.  The  proposal  to  determine 

32 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
 
 
  
how often the say on pay proposal should be voted on by shareholders will again be brought to a shareholder 
vote in 2022.  

We believe that our compensation policies and procedures are  centered on a pay-for-performance culture and 
are strongly aligned with the long-term interests of our shareholders. Our incentive compensation plan provides 
for  the  grant  of  incentive  stock  options,  non-qualified  stock  options,  stock  appreciation  rights,  and  restricted 
performance  shares.  The  Summary  Compensation  Table  shows  very  stable  base  salaries  indicative  of  our 
greater emphasis on performance-based stock and non-stock awards. Our stock and option awards are based on 
a minimum achievement of meeting the “threshold” level for each pre-established objective. Both awards have 
a  three-year  vesting  period.  Our  annual  incentive  plan  incorporates  at  least  four  financial  and/or  strategic 
performance  metrics  in  order  to  properly  balance  risk  with  the  incentives  to  drive  our  key  annual  financial 
and/or strategic initiatives; in addition, the annual incentive program incorporates a 150% maximum payout to 
further manage risk and the possibility of excessive payments.  

In 2003, shareholders approved the Company’s 2003 Amended Plan to include the following changes: 

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

  Limiting the number of shares that may be awarded; and 

  Requiring the  Compensation  Committee to  meet the definition of independence to  enable any award 
intended  to  qualify  as  “performance-based  compensation”  to  meet  Section  162(m)  of  the  Internal 
Revenue Code. 

In  2009,  shareholders  re-approved  the  performance  criteria  for  performance-based  awards  under  the  2003 
Amended Plan. 

In 2012, shareholders approved the Company’s 2012 Amended and Restated Stock Option Plan of 1995.  The 
2012 Amended Plan includes the following changes: 

  Reduced the number of shares available for future issuance from 4,307,593 to 1,500,000 (plus shares 
that  become  available  if  awards  under  prior  plans  expire  unexercised  or  are  cancelled,  forfeited  or 
terminated before being exercised); and 

  Extended the term of the 2012 Amended Plan to April 26, 2022 from April 24, 2013. 

Vote Required  

The “say on pay” proposal gives you as a shareholder the opportunity to endorse or not endorse our executive 
pay program through the following resolution: 

“Resolved, that the shareholders approve, on an advisory basis, the compensation of the named 
executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities 
and  Exchange  Commission,  which  disclosure  includes  the  compensation  discussion  and 
analysis,  the  compensation  tables  and  any  related  footnotes  and  narratives  in  the  Company’s 
proxy statement for the Annual Meeting of Shareholders.” 

Because your vote is advisory, it will not be binding on the Board or create or imply any additional fiduciary 
duty by the Board. However, the Compensation Committee may take into account the outcome of the vote when 
considering future executive compensation arrangements.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A 
 VOTE “FOR” THE APPROVAL OF THE COMPENSATION OF OUR NAMED 
EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT 
PURSUANT TO THE COMPENSATION DISCLOSURE RULES OF THE 
SECURITIES AND EXCHANGE COMMISSION 

PROPOSAL 3 – APPROVE THE 2019 OMNIBUS EQUITY INCENTIVE PLAN  

Introduction  

On February 28, 2019, the Board of Directors adopted the 2019 Omnibus Equity Incentive Plan (the “2019 Plan”), 
subject to shareholder approval. The 2019 Plan will become effective, if at all, on the date that it is approved by the 
Company’s shareholders (the “Effective Date”). 

The Company currently maintains the 2012 Amended and Restated Stock Option Plan of 1995 (the “Prior Plan”). 
Following the Effective Date, no further awards may be issued under the Prior Plan, but all awards under the Prior 
Plan  that  are  outstanding  as  of  the  Effective  Date  will  continue  to  be  governed  by  the  terms,  conditions  and 
procedures set forth in the Prior Plan and any applicable award agreement.  

Under the 2019 Plan, a total of 1,235,898 shares of Company common stock are available for grant, comprised of  
750,000  shares  of  Company  common  stock  initially  reserved  for  issuance  under  the  2019  Plan  plus  485,898 
additional shares of Company common stock that are currently available for grant under the Prior Plan. 

The Compensation Committee may grant restricted stock, incentive stock options, non-qualified stock options, stock 
appreciation rights, restricted stock units and other share-based awards to participants to acquire shares of Company 
common stock to the Company’s officers and employees under the 2019 Plan.  As of February 25, 2019, there were 
approximately thirty-four employees eligible to participate in the 2019 Plan. 

Rationale for Adoption of the 2019 Plan 

Grants of options to employees are an important part of the Company’s long-term incentive compensation program, 
which  the  Company  uses  to  strengthen  the  commitment  of  such  individuals  to  the  Company,  motivate  them  to 
faithfully  and  diligently  perform  their  responsibilities  and  attract  and  retain  competent  and  dedicated  individuals 
whose efforts are expected to result in the Company’s long-term growth and profitability.   

Vote Required 

You may vote “FOR” or “AGAINST” or “ABSTAIN” from voting when voting on the approval of the 2019 Plan. 
The  2019 Plan  will  be  approved  if  it  receives  the  affirmative  vote  of  a  majority  of  the  total  number  of  votes  of 
common stock represented at the annual meeting and entitled to vote thereon. Proxies solicited by the Board will be 
voted “FOR” the 2019 Plan unless shareholders specify a contrary vote.  

The Board recommends that you vote “FOR” the approval of the 2019 Plan.  

Dilution, Shares Available and Historical Share Usage 

Dilution.  Subject  to  shareholder  approval  of  the  2019  Plan,  750,000  shares  of  Company  common  stock  will  be 
reserved for issuance under the 2019 Plan as of  February 25, 2019, which represents approximately  2.8% of the 
Company’s issued and outstanding shares, not including shares underlying outstanding awards under the Prior Plan. 

34 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
 
The  Board  believes  that  this  number  of  shares  constitutes  reasonable  potential  equity  dilution  and  provides  a 
significant incentive for employees to increase the value of the Company for all shareholders. The closing trading 
price of each share of common stock as of the record date was $64.40. 

As of the record date, there were: (i) 26,890,495 shares of common stock outstanding and (ii) 807,399 stock options 
outstanding  (vested  and  unvested),  with  a  weighted  average  exercise  price  of  $57.80  per  share.  The  new  shares 
available under the 2019 Plan would represent an additional potential equity dilution of approximately 2.8%, which 
does not include outstanding awards under the Prior Plan. Including the proposed additional shares under the 2019 
Plan, the potential equity dilution from all equity incentive awards outstanding and available for grant under all of 
the Company’s equity plans would result in a maximum potential equity dilution of approximately 7.6%. 

Shares Available; Certain Limitations. The maximum number of shares of common stock reserved and available for 
issuance under the 2019 Plan will be equal to the sum of (i) 750,000 shares of common stock plus (ii) the number of 
shares of common stock reserved, but unissued under the Prior Plan (485,898 as of February 25, 2019), provided 
that shares of common stock issued under the 2019 Plan with respect to an Exempt Award will not count against the 
share limit. “Exempt Award” means (i) an award granted in the assumption of, or in substitution for, outstanding 
awards previously granted by another business entity acquired by the Company or any subsidiary of the Company 
or with  which the Company or any of its subsidiaries merges or (ii) an award that a participant purchases at fair 
market value. 

New shares reserved for issuance under the 2019 Plan may be authorized but unissued shares or outstanding shares 
that  may  be  reacquired  by  the  Company  in  the  open  market,  in  private  transactions  or  otherwise.  If  any  shares 
subject to an award are forfeited, cancelled, exchanged or surrendered or if an award terminates or expires without a 
distribution of shares to the participant, the shares of Company common stock with respect to such award will, to the 
extent  of  any  such  forfeiture,  cancellation,  exchange,  surrender,  withholding,  termination  or  expiration,  again  be 
available for awards under the 2019 Plan except that any shares of Company common stock surrendered or withheld 
as payment of either the exercise price of an award and/or withholding taxes in respect of an award will not again be 
available for awards under the 2019 Plan.  

As exhibited by the Company’s responsible use of equity over the past several years and good corporate governance 
practices associated with equity and executive compensation practices in general, the shares reserved under the 2019 
Plan should provide the Company with the platform needed for continued growth, while managing program costs 
and share utilization levels within acceptable industry standards. 

Share Usage. In determining the requested number of shares reserved for issuance under the 2019 Plan, the Board of 
Directors  evaluated  the dilution  and  historic  share  usage,  burn  rate  and  the existing  terms  of  outstanding  options 
under the Prior Plan. The annual share usage under the Prior Plan for the last three fiscal years was as follows:

Description of 2019 Plan 

The following is a summary of the material features of the 2019 Plan. This summary is qualified in its entirety by 
the full text of the 2019 Plan, a copy of which is attached to this Proxy Statement as Exhibit B. 

Types of Awards. The 2019 Plan provides for the issuance of options, share appreciation rights (“SARs”), restricted 
shares, restricted stock units (“RSUs”) and other share-based awards to the Company’s officers and employees. 

Shares of common  stock subject to an award under the 2019 Plan that remain unissued upon the cancellation or 
termination of the award will again become available for grant under the 2019 Plan. However, shares of common 
stock  that  are  surrendered  by  a  participant  or  withheld  as  payment  of  the  exercise  price  in  connection  with  any 
award under the 2019 Plan, as well as any shares of common stock exchanged by a participant or withheld to satisfy 
tax withholding obligations related to any award, will not be available for subsequent awards under the 2019 Plan. 
However, upon the exercise of any award granted in tandem  with any other awards, such related awards  will be 
cancelled as to the number of shares as to which the award is exercised and such number of shares will no longer be 
available for grant under the 2019 Plan.  

Administration.  The  2019  Plan  may  be  administered  by  the  Board  of  Directors  or  a  committee  of  the  Board  of 
Directors  that  complies  with  the  applicable  requirements  of  Section  16  of  the  Exchange  Act  and  any  other 
applicable legal or stock exchange listing requirements, such as the Compensation Committee (each of the Board of 
Directors or such committee, the “plan administrator”). The plan administrator may interpret the 2019 Plan and may 
prescribe, amend and rescind rules and make all other determinations necessary or desirable for the administration 
of  the  2019  Plan,  provided  that,  subject  to  the  equitable  adjustment  provisions  described  below,  the  plan 
administrator will not have the authority to reprice or cancel and re-grant any award at a lower exercise, base or 
purchase price or cancel any award with an exercise, base or purchase price in exchange for cash, property or other 
awards without first obtaining the approval of the Company’s shareholders. 

The 2019 Plan permits the plan administrator to select the eligible recipients who will receive awards, to determine 
the terms and conditions of those awards, including but not limited to the exercise price or other purchase price of an 
award, the number of shares of common stock subject to an award, the term of an award and the vesting schedule 
applicable to an award, and to amend the terms and conditions of outstanding awards. 

While  the  2019 Plan  generally  permits  the  plan  administrator  to determine  the  vesting  schedule  applicable  to an 
award, any awards granted under the 2019 Plan will be granted subject to a minimum vesting period of at least 12 
months, subject to acceleration in connection with a change in control, as discussed below. The administrator is not 
permitted  to  accelerate  the  vesting  of  any  award  granted  under  the  2019  Plan,  though  awards  would  vest,  in 
connection with a change in control, as discussed below. 

Options. The Company may issue non-qualified stock options and “incentive stock options” (“ISOs”) (within the 
meaning of Section 422 of the Internal Revenue Code (the “Code)) under the 2019 Plan. The terms and conditions 
of any options granted to a participant will be set forth in an award agreement and, subject to the provisions in the 
2019 Plan, will be determined by the plan administrator. The exercise price of any option granted under the 2019 
Plan  must  be  at  least  equal  to  the  fair  market  value  of  the  Company’s  common  stock  on  the  date  the  option  is 
granted (110% of fair market value in the case of ISOs granted to ten percent shareholders). The maximum term of 
an option granted under the 2019 Plan is ten years. The amount of incentive stock options that become exercisable 
for the first time in a particular year cannot exceed a value of $100,000 per participant, determined using the fair 
market value of the shares on the date of grant. 

36 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
Subject to the 2019 Plan, the plan administrator will determine the vesting and other terms and conditions of options 
granted under the 2019 Plan. Treatment of an option upon termination of employment of a participant will specified 
the applicable award agreement as determined by the plan administrator. 

Restricted  Shares  and  RSUs.  Restricted  shares  and  RSUs  may  be  granted  under  the  2019  Plan.  The  plan 
administrator will determine the purchase price, vesting schedule and performance goals, if any, applicable to the 
grant  of  restricted  shares  or  RSUs.  Unless  otherwise  determined  by  the  plan  administrator,  if  the  restrictions, 
performance goals or other conditions determined by the plan administrator are not satisfied, the restricted shares 
and  RSUs  will  be  forfeited.  Subject  to  the  provisions  of  the  2019  Plan  and  the  applicable  individual  award 
agreement, the plan administrator has the sole discretion to provide for the lapse of restrictions in installments. The 
rights  of  restricted  share  and  RSU  holders  upon  a  termination  of  employment  or  service  will  be  set  forth  in 
individual award agreements as determined by the plan administrator. 

Unless the applicable award agreement provides otherwise, participants with restricted shares will generally have all 
of  the  rights  of  a  shareholder  during  the  restricted  period,  including  the  right  to  receive  dividends  declared  with 
respect to such shares; provided, however, that dividends declared during the restricted period with respect to an 
award will only become payable if (and to the extent) that the underlying restricted shares vest. During the restricted 
period, participants with RSUs will generally not have any rights of a shareholder, but will be credited with dividend 
equivalent rights, unless the applicable individual award agreement provides otherwise. 

Share Appreciation Rights. SARs may be granted under the 2019 Plan either alone or in conjunction with all or part 
of any option granted under the 2019 Plan. A free-standing SAR granted under the 2019 Plan entitles its holder to 
receive, at the time of exercise, an amount per share up to the excess of the fair market value (at the date of exercise) 
of a share of common stock over the exercise price of the free-standing SAR multiplied by the number of shares in 
respect of which the SAR is being exercised. An SAR granted in conjunction with all or part of an option under the 
2019 Plan entitles its holder to receive, at the time of exercise of the SAR and surrender of the related option, an 
amount per share up to the excess of the fair market value (at the date of exercise) of a share of common stock over 
the exercise price of the related option multiplied by the number of shares in respect of which the SAR is being 
exercised. Each SAR will be granted with an exercise price that is not less than 100% of the fair market value of the 
related shares of common stock on the date of grant. Treatment of an SAR upon termination of employment of a 
participant  will  be  specified  in  the  applicable  award  agreement  as  determined  by  the  plan  administrator.  The 
maximum term of all SARs granted under the 2019 Plan will be determined by the plan administrator, but may not 
exceed ten years. The plan administrator may determine to settle the exercise of an SAR in shares of common stock, 
cash, or any combination thereof. 

Each free-standing SAR will vest and become exercisable (including in the event of the SAR holder’s termination of 
employment  or  service)  at  such  time  and  subject  to  such  terms  and  conditions  as  determined  by  the  plan 
administrator in the applicable individual free-standing SAR  agreement. SARs granted in conjunction with all or 
part of an option will be exercisable at such times and subject to all of the terms and conditions applicable to the 
related option. 

Other  Share-Based  Awards.  Other  share-based  awards,  valued  in  whole  or  in  part  by  reference  to,  or  otherwise 
based on, shares of common stock (including dividend equivalents) may be granted under the 2019 Plan. The plan 
administrator will determine the terms and conditions of such other share-based awards, including the number of 
shares of common stock to be granted pursuant to such other share-based awards, the manner in which such other 
share-based awards will be settled (e.g., in shares of common stock, cash or other property), and the conditions to 
the vesting and payment of such other share-based awards (including the achievement of performance goals). The 

37 

2019     WESTAMERICA BANCORPORATION PROXY 
 
 
rights of participants granted other share-based awards upon the termination of employment with or service to us 
will be set forth in the award agreement. Any dividend or dividend-equivalent award issued under the 2019 Plan 
will be subject to the same restrictions and conditions as apply to the underlying award.  

Equitable Adjustments. In the event of a merger, consolidation, reclassification, recapitalization, spin-off, spin-out, 
repurchase, reorganization, special or extraordinary dividend or other extraordinary distribution (whether in the form 
of common shares, cash or other property), combination, exchange of shares, or other change in corporate structure 
affecting the common stock, an equitable substitution or proportionate adjustment shall be made in (i) the aggregate 
number  and  kind  of  securities  reserved  for  issuance  under  the  2019  Plan,  (ii)  the  kind  and  number  of  securities 
subject to, and the exercise price of, any outstanding options and SARs granted under the 2019 Plan, (iii) the kind, 
number and purchase price of shares of common stock, or the amount of cash or amount or type of property, subject 
to outstanding restricted shares, RSUs and other share-based awards granted under the 2019 Plan and (iv) the terms 
and conditions of any outstanding awards (including any applicable performance targets). Equitable substitutions or 
adjustments other than those listed above may also be made as determined by the plan administrator. In addition, the 
plan administrator may terminate all outstanding awards for the payment of cash or in-kind consideration having an 
aggregate fair market value equal to the excess of the fair market value of the shares of common stock, cash or other 
property covered by such awards over the aggregate exercise price, if any, of such awards, but if the exercise price 
of any outstanding award is equal to or greater than the fair market value of the shares of common stock, cash or 
other property covered by such award, the Board of Directors may cancel the award without the payment of any 
consideration  to  the  participant.  With  respect  to  awards  subject  to  foreign  laws,  adjustments  will  be  made  in 
compliance with applicable requirements. Except to the extent determined by the plan administrator, adjustments to 
incentive  stock  options  will  be  made  only  to  the  extent  not  constituting  a  “modification”  within  the  meaning  of 
Section 424(h)(3) of the Code. 

Change  in  Control  and  Qualifying  Termination.  Unless  otherwise  determined  by  the  plan  administrator  and 
evidenced in an award agreement, in the event that (i) a “change in control” (as defined below) occurs and (ii) a 
participant is employed immediately prior to the change in control, then upon the consummation of the change in 
control (a) any unvested or unexercisable portion of any award carrying a right to exercise will become fully vested 
and exercisable, and (b) the restrictions, deferral limitations, payment conditions and forfeiture conditions applicable 
to  any  award  will  lapse  and  such  unvested  awards  will  be  deemed  fully  vested  and  any  performance  conditions 
imposed  with  respect  to  such  awards  will  be  deemed  to  be  fully  achieved  at  target  performance  levels.  The 
administrator  may  provide  that,  in  connection  with  such  change  in  control,  all  options  and/or  SARs  outstanding 
immediately prior to such change in control shall expire upon the consummation of such change in control if not 
exercised upon, or prior to, such change in control. 

Definition of Change in Control. For purposes of the 2019 Plan, a “change in control” will mean, in summary, the 
first  to  occur  of  the  following  events:  (i)  a  person  or  entity  becomes  the  beneficial  owner  of  more  than  50%  of 
voting power of the Company; (ii) an unapproved change in the majority membership of the Board of Directors; (iii) 
a merger or consolidation of the Company or any of its subsidiaries, other than (A) a merger or consolidation that 
results in the Company’s voting securities continuing to represent 50% or more of the combined voting power of the 
surviving entity or its parent 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  its  parent  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) shareholder approval 
of  a  plan  of  complete  liquidation  or  dissolution  of  us  or  the  consummation  of  an  agreement  for  the  sale  or 
disposition of substantially all of the Company’s assets, other than a sale or disposition to an entity, more than 50% 
of  the  combined  voting  power  of  which  is  owned  by  the  Company’s  shareholders  in  substantially  the  same 

38 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
proportions as their ownership of the Company immediately prior to such sale or a sale or disposition to an entity 
controlled by the Board of Directors. However, a change in control will not be deemed to have occurred as a result 
of  any  transaction  or  series of  integrated  transactions  following  which  the  Company’s  shareholders,  immediately 
prior  thereto,  hold  immediately  afterward  the  same  proportionate  equity  interests  in  the  entity  that  owns  all  or 
substantially all of the Company’s assets.  

Tax  Withholding.  Each  participant  will  be  required  to  make  arrangements  satisfactory  to  the  plan  administrator 
regarding payment of up to the maximum statutory tax rates in the participant’s applicable jurisdiction with respect 
to any award granted under the 2019 Plan, as determined by the Company. The Company has the right, to the extent 
permitted  by  applicable  law,  to  deduct  any  such  taxes  from  any  payment  of  any  kind  otherwise  due  to  the 
participant. With the approval of the plan administrator, the participant may satisfy the foregoing requirement by 
either electing to have us withhold from delivery of shares of common stock, cash or other property, as applicable, 
or by delivering already owned unrestricted shares of common stock, in each case, having a value not exceeding the 
applicable taxes to be withheld and applied to the tax obligations. The Company may also use any other method of 
obtaining the necessary payment or proceeds, as permitted by applicable law, to satisfy the Company’s withholding 
obligation with respect to any award. 

Amendment and Termination of the 2019 Plan. The 2019 Plan provides the Board of Directors with authority to 
amend, alter or terminate the 2019 Plan, but no such action may impair the rights of any participant with respect to 
outstanding awards without the participant’s consent. The plan administrator may amend an award, prospectively or 
retroactively, but no such amendment may materially impair the rights of any participant without the participant’s 
consent. Shareholder approval of any such action will be obtained if required to comply with applicable law. The 
2019  Plan  does  not  permit  the  repricing  or  cancelation  and  regarding  of  any  award  at  a  lower  exercise,  base  or 
purchase price without the approval of the Company’s shareholders. 

2019  Plan  Term.  The  2019  Plan  will  terminate  on  the  tenth  anniversary  of  the  Effective  Date,  although  awards 
granted before that time will remain outstanding in accordance with their terms. 

Clawback. If the Company is required to prepare a financial restatement due to the material non-compliance with 
any  financial  reporting  requirement,  then  the  plan  administrator  may  require  any  Section  16  officer  to  repay  or 
forfeit to the Company that part of the cash or equity incentive compensation received by that Section 16 officer 
during  the  preceding  three  years  that  the  plan  administrator  determines  was  in  excess  of  the  amount  that  such 
Section 16 officer would have received had such cash or equity incentive compensation been calculated based on 
the financial results reported in the restated financial statement. The plan administrator may take into account any 
factors it deems reasonable in determining whether to seek recoupment of previously paid cash or equity incentive 
compensation and how much of such compensation to recoup from each Section 16 officer (which need not be the 
same amount or proportion for each Section 16 officer).  

United States Federal Income Tax Consequences 

The following is a summary of certain United States federal income tax consequences of awards under the 2019 
Plan.  It  does  not  purport  to  be  a  complete  description  of  all  applicable  rules,  and  those  rules  (including  those 
summarized here) are subject to change. 

Non-Qualified Stock Options. A participant who has been granted a non-qualified stock option will not recognize 
taxable income upon the grant of a non-qualified stock option. Rather, at the time of exercise of such non-qualified 
stock  option,  the  participant  will  recognize  ordinary  income  for  income  tax  purposes  in  an  amount  equal  to  the 
excess  of  the  fair  market  value  of  the  shares  purchased  over  the  exercise  price.  The  Company  generally  will  be 
39 

2019     WESTAMERICA BANCORPORATION PROXY 
 
 
entitled to a tax deduction at such time and in the same amount that the participant recognizes ordinary income. If 
shares  acquired  upon  exercise  of  a  non-qualified  stock  option  are  later  sold  or  exchanged,  then  the  difference 
between the amount received upon such sale or exchange and the fair market value of such shares on the date of 
such exercise will generally be taxable as long-term or short-term capital gain or loss (if the shares are a capital asset 
of the participant) depending upon the length of time such shares were held by the participant. 

Incentive Stock Options. In general, no taxable income is realized by a participant upon the grant of an ISO. If shares 
of common stock are purchased by a participant, or option shares, pursuant to the exercise of an ISO granted under 
the 2019 Plan and the participant does not dispose of the option shares within the two-year period after the date of 
grant or within one year after the receipt of such option shares by the participant, such disposition a disqualifying 
disposition, then, generally (1) the participant will not realize ordinary income upon exercise and (2) upon sale of 
such option shares, any amount realized in excess of the exercise price paid for the option shares will be taxed to 
such participant as capital gain (or loss). The amount by which the fair market value of the common stock on the 
exercise date of an ISO exceeds the purchase price generally will constitute an item which increases the participant’s 
“alternative minimum taxable income.” If option shares acquired upon the exercise of an ISO are disposed of in a 
disqualifying disposition, the participant generally would include in ordinary income in the year of disposition an 
amount  equal  to  the  excess  of  the  fair  market  value  of  the  option  shares  at  the  time  of  exercise  (or,  if  less,  the 
amount realized on the disposition of the option shares), over the exercise price paid for the option shares. Subject to 
certain  exceptions,  an  option  generally  will  not  be  treated  as  an  ISO  if  it  is  exercised  more  than  three  months 
following termination of employment. If an ISO is exercised at a time when it no longer qualifies as an ISO, such 
option will be treated as a nonqualified stock option as discussed above. In general, the Company will receive an 
income tax deduction at the same time and in the same amount as the participant recognizes ordinary income. 

Share Appreciation Rights. A participant who is granted an SAR generally will not recognize ordinary income upon 
receipt of the SAR. Rather, at the time of exercise of such SAR, the participant will recognize ordinary income for 
income tax purposes in an amount equal to the value of any cash received and the fair market value on the date of 
exercise of any shares received. The Company generally will be entitled to a tax deduction at such time and in the 
same amount, if any, that the participant recognizes as ordinary income. The participant’s tax basis in any common 
shares received upon exercise of an SAR will be the fair market value of the shares of common stock on the date of 
exercise, and if the shares are later sold or exchanged, then the difference between the amount received upon such 
sale or exchange and the fair market value of such shares on the date of exercise will generally be taxable as long-
term or short-term capital gain or loss (if the shares are a capital asset of the participant) depending upon the length 
of time such shares were held by the participant. 

Restricted  Shares.  A  participant  generally  will  not  be  taxed  upon  the  grant  of  restricted  shares,  but  rather  will 
recognize ordinary income in an amount equal to the fair market value of the shares at the earlier of the time the 
shares  become  transferable  or are  no  longer  subject  to  a  substantial  risk  of  forfeiture  (within  the  meaning  of  the 
Code).  The  Company  generally  will  be  entitled  to  a  deduction  at  the  time  when,  and  in  the  amount  that,  the 
participant recognizes ordinary income on account of the lapse of the restrictions. A participant’s tax basis in the 
shares will equal their fair market value at the time the restrictions lapse, and the participant’s holding period for 
capital gains purposes will begin at that time. Any cash dividends paid on the shares before the restrictions lapse will 
be taxable to the participant as additional compensation and not as dividend income, unless the individual has made 
an election under Section 83(b) of the Code. Under Section 83(b) of the Code, a participant may elect to recognize 
ordinary income at the time the restricted shares are awarded in an amount equal to their fair market value at that 
time,  notwithstanding  the  fact  that  such  shares  are  subject  to  restrictions  or  transfer  and  a  substantial  risk  of 
forfeiture. If such an election is made, no additional taxable income will be recognized by such participant at the 
time the restrictions lapse, the participant will have a tax basis in the shares equal to their fair market value on the 

40 

2019   WESTAMERICA BANCORPORATION PROXY 
 
 
date  of  their  award,  and  the  participant’s  holding  period  for  capital  gains  purposes  will  begin  at  that  time.  The 
Company will generally will be entitled to a tax deduction at the time when, and to the extent that, ordinary income 
is recognized by such participant. 

RSUs.  In  general,  the  grant  of  RSUs  will  not  result  in  income  for  the  participant  or  in  a  tax  deduction  for  the 
Company. Upon the settlement of such an award in cash or shares, the participant will recognize ordinary income 
equal to the aggregate value of the payment received, and the Company generally will be entitled to a tax deduction 
at the same time and in the same amount. 

Other  Awards.  With  respect  to  other  awards  granted  under  the  2019  Plan,  including  other  share-based  awards, 
generally when the participant receives payment with respect to an award, the amount of cash and/or the fair market 
value of any common shares or other property received will be ordinary income to the participant, and the Company 
generally will be entitled to a tax deduction at the same time and in the same amount. 

New Plan Benefits 

Future grants under the 2019 Plan will be made at the discretion of the plan administrator and, accordingly, are not 
yet determinable. In addition, benefits under the 2019 Plan will depend on a number of factors, including the fair 
market  value  of  the  Company’s  common  stock  on  future  dates  and  the  exercise  decisions  made  by  participants. 
Consequently, at this time, it is not possible to determine the future benefits that might be received by participants 
receiving discretionary grants under the 2019 Plan.  

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A 
 VOTE “FOR” THE APPROVAL OF THE 2019 OMNIBUS EQUITY INCENTIVE 
PLAN 

PROPOSAL 4 – RATIFY SELECTION OF INDEPENDENT AUDITOR   

Ratify Selection of Independent Auditor 

Action  by  the  shareholders  is  not  required  by  law  in  the  appointment  of  independent  auditors,  but  their 
appointment is submitted by the Audit Committee and the Board of Directors in order to give the shareholders 
an opportunity to present their views. If the proposal is approved, the Audit Committee, in its discretion, may 
direct the appointment of different independent auditors at any time during the year if it determines that such a 
change would be in the best interests of the Company and its shareholders. If the proposal to ratify the selection 
of  Crowe  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.

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 2018, there were no non-audit services that were provided using this exception. 

The  Audit  Committee  may  delegate  to  one  or  more  members  of  the  Audit  Committee  the  authority  to  grant 
preapprovals  of  non-audit  services  and  fees.  In  such  event,  the  decisions  of  the  member  or  members  of  the 
Committee  regarding  preapprovals  are  presented  to  the  full  Audit  Committee  at  its  next  meeting.  The  Audit 
Committee  preapproved  100%  of  all  services  performed  for  the  Company  by  Crowe  LLP  during  fiscal  year 
2018.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE 
RATIFICATION OF THE SELECTION OF CROWE LLP AS OUR INDEPENDENT 
REGISTERED PUBLIC ACCOUNTING FIRM 

AUDIT COMMITTEE REPORT 

The material in this report is not soliciting material and is not deemed filed with the SEC. It is not incorporated 
by reference in any of the  Company’s  filings under the Securities  Act of 1933 or the Exchange  Act,  whether 
made in the past or in the future even if any of those filings contain any general incorporation language. 

The Audit Committee is composed of four Directors who are neither officers nor employees of the Company, 
and who meet the NASDAQ independence requirements for Audit Committee members. The Audit Committee 
selects, appoints and retains the Company’s independent auditors and is responsible for their compensation and 
oversight. 

In performing its functions, the Audit Committee acts only in an oversight capacity and necessarily relies on the 
work  and  assurances  of  the  Company’s  management,  which  has  the  primary  responsibility  for  financial 
statements and reports, and of the independent auditors. The auditors express an opinion on the conformity of 
the  Company’s  annual  financial  statements  to  United  States  generally  accepted  accounting  principles  and  on 
internal  control  over  financial  reporting.  In  fulfilling  its  oversight  responsibilities,  the  Audit  Committee 
reviewed  the  audited  consolidated  financial  statements  for  the  fiscal  year  2018  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, 
2018, 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, 2018 for filing with the SEC.

Meeting, shareholder proposals must be delivered to the Corporate Secretary, Westamerica Bancorporation A-
2M, P.O. Box 1200, Suisun City, CA 94585, no  later than 5:00 p.m. on  November 11, 2019. However, if the 
date of next year’s Annual Meeting is changed by more than 30 days from the date of this year’s meeting, the 
notice must be received by the Corporate Secretary a reasonable time before we begin to produce and distribute 
our Proxy Statement. All such proposals must meet the requirements of Rule 14a-8 under the Exchange Act. 

In order for business, other than a shareholder proposal submitted for the  Company’s  Proxy  Statement,  to be 
properly brought before next year’s Annual Meeting by a shareholder, the shareholder must give timely written 
notice to the Corporate Secretary. To be timely, written notice must be received by the Corporate Secretary at 
least 45 days before the anniversary of the day our Proxy Statement was mailed to shareholders in connection 
with the previous year’s Annual Meeting or January 24, 2020, for the 2020 Annual Meeting. If the date of the 
Annual Meeting is changed by more than 30 days, the deadline is a reasonable time before we begin to produce 
and  distribute  our  Proxy  Statement.  A  shareholder’s  notice  must  set  forth  a  brief  description  of  the  proposed 
business, the name and residence address of the shareholder, the number of shares of the Company’s common 
stock  that  the  shareholder  owns  and  any  material  interest  the  shareholder  has  in  the  proposed  business.    The 
Company  will  have  discretionary  voting  authority  with  respect  to  any  non-Rule  14a-8  proposals  for  the  next 
annual shareholders meeting that are not received by January 24, 2020. 

Westamerica reserves the right to reject, to rule out of order, or to take other appropriate action with respect to 
any proposal that does not comply with these and other applicable legal requirements. 

SHAREHOLDER COMMUNICATION TO BOARD OF DIRECTORS 

Shareholders and other interested parties  who  wish to communicate  with the Board  may do so by  writing  to: 
Kris  Irvine,  VP/Corporate  Secretary,  Westamerica  Bancorporation  A-2M,  P.O.  Box  1200,  Suisun  City,  CA 
94585. The Directors have  established procedures for the handling of communications from  shareholders and 
other  interested  parties  and  have  directed  the  Corporate  Secretary  to  act  as  their  agent  in  processing  any 
communications received. All communications that relate to matters that are within the responsibility of one of 
the  Board  Committees  are  to  be  forwarded  to  the  Chair  of  the  appropriate  Committee.  Communications  that 
relate to ordinary business matters that are not within the scope of the Board’s responsibilities, such as customer 
complaints,  are  to  be  sent  to  Management.  Solicitations,  junk  mail  and  obviously  frivolous  or  inappropriate 
communications are not to be forwarded, but will be made available to any Director who wishes to review them. 

OTHER MATTERS 

The Board of Directors does not know of any matters to be presented at the Annual Meeting other than those 
specifically referred to in this Proxy Statement. If any other matters should properly come before the meeting or 
any  postponement  or  adjournment  of  the  meeting,  the  persons  named  in  the  enclosed  proxy  intend  to  vote 
thereon in accordance with their best business judgment. If a nominee for Director becomes unavailable to serve 
as a Director, the Proxies will vote for any substitute nominated by the Board of Directors. 

The Company will pay the cost of proxy solicitation. The Company has retained the services of Georgeson to 
assist  in  the  proxy  distribution  at  a  cost  not  to  exceed  $2,000  plus  reasonable  out-of-pocket  expenses.  The 
Company  will  reimburse  banks,  brokers  and  others  holding  stock  in  their  names  or  names  of  nominees  or 
otherwise, for reasonable out-of-pocket expenses incurred in sending proxies and proxy materials to the holders 
of such stock.

of management and the corporate staff, and other members of the Board as deemed appropriate, and may engage a 
professional search firm if the Committee deems it appropriate to do so. The Company shall provide appropriate 
funding,  as  determined  by  the  Committee,  for  payment  of  compensation  to  any  advisors  employed  by  the 
Committee  and  ordinary  administrative  expenses  that  the  Committee  deems  to  be  necessary  or  appropriate  in 
carrying out its duties. The Committee or a member or members of the Committee designated by the Committee

Shares Reserved for Issuance Under the Plan. 

(a) 

Subject to Section 5 hereof, the number of shares of Common Stock that are reserved 
and available for issuance pursuant to Awards granted under the Plan shall be equal to 750,000 shares, plus the 
number  of  shares  of  Common  Stock  reserved,  but  unissued,  under  the  Prior  Plan;  provided,  that,  shares  of 
Common Stock issued under the Plan with respect to an Exempt Award shall not count against such share limit. 
Following the Effective Date, no further awards shall be issued under the Prior Plan, but all awards under the 
Prior  Plan  which  are  outstanding  as  of  the  Effective  Date  (including  any  Grandfathered  Arrangement)  shall 
continue to be governed by the terms, conditions and procedures set forth in the Prior Plan and any applicable 
Award Agreement.  

(b) 

Shares  issued  under  the  Plan  may,  in  whole  or  in  part,  be  authorized  but  unissued 
Shares  or  Shares  that  shall  have  been  or  may  be  reacquired  by  the  Company  in  the  open  market,  in  private 
transactions  or  otherwise.  If  an  Award  entitles  the  Participant  to  receive  or  purchase  Shares,  the  number  of 
Shares covered by  such  Award or to which such  Award relates shall be counted on the  date  of grant of such 
Award  against  the  aggregate  number  of  Shares  available  for  granting  Awards  under  the  Plan.  If  any  Shares 
subject to an Award are forfeited, cancelled, exchanged or surrendered or if an Award otherwise terminates or 
expires without a distribution of shares to the Participant, the Shares with respect to such Award shall, to the 
extent of any such forfeiture, cancellation, exchange, surrender, termination or expiration, again be available for 
granting Awards under the Plan. Notwithstanding the foregoing, Shares surrendered or withheld as payment of 
either the Exercise Price of an Award (including Shares otherwise underlying a Share Appreciation Right that 
are  retained  by  the  Company  to  account  for  the  Exercise  Price  of  such  Share  Appreciation  Right)  and/or 
withholding  taxes  in  respect  of  an  Award  shall  no  longer  be  available  for  grant  under  the  Plan.  Upon  the 
exercise of any Award granted in tandem with any other Awards, such related Awards shall be cancelled to the 
extent  of  the  number  of  Shares  as  to  which  the  Award  is  exercised  and,  notwithstanding  the  foregoing,  such 
number of shares shall no longer be available for grant under the Plan. 

(c) 

No more than 200,000 Shares shall be issued pursuant to the exercise of ISOs.  

Notwithstanding  anything  to  the  contrary  in  the  Plan  except  for  Section  12  of  the 
Plan, any Awards granted under the Plan shall be granted subject to a minimum vesting period of at least twelve 
(12) months.

Section 5. 

Equitable Adjustments. 

In  the  event  of  any  Change  in  Capitalization,  an  equitable  substitution  or  proportionate 
adjustment shall be made in (i) the aggregate number and kind of securities reserved for issuance under the Plan 
pursuant to Section 4, (ii) the kind, number of securities subject to, and the Exercise Price subject to outstanding 
Options  and  Share  Appreciation  Rights  granted  under  the  Plan,  (iii) the  kind,  number  and  purchase  price  of 
Shares  or  other  securities  or  the  amount  of  cash  or  amount  or  type  of  other  property  subject  to  outstanding 
Restricted Shares, Restricted Stock Units or Other Share-Based Awards granted under the Plan; and/or (iv) the 
terms  and  conditions  of  any  outstanding  Awards  (including,  without  limitation,  any  applicable  performance 
targets  or  criteria  with  respect  thereto);  provided,  however,  that  any  fractional  shares  resulting  from  the 
adjustment  shall  be  eliminated.  Such  other  equitable  substitutions  or  adjustments  shall  be  made  as  may  be 
determined  by  the  Administrator,  in  its  sole  discretion.  Without  limiting  the  generality  of  the  foregoing,  in 
connection with a Change in Capitalization, the Administrator may provide, in its sole discretion, but subject in 
all  events  to  the  requirements  of  Section  409A  of  the  Code,  for  the  cancellation  of  any  outstanding  Award 
granted  hereunder in exchange for payment in cash or other property  having an aggregate  Fair Market Value 
equal to the Fair Market Value  of the Shares, cash or other property covered by such  Award, reduced by the 
aggregate  Exercise  Price  or  purchase  price  thereof,  if  any;  provided,  however,  that  if  the  Exercise  Price  or 
purchase  price  of  any  outstanding  Award  is  equal  to  or  greater  than  the  Fair  Market  Value  of  the  shares  of 
Common  Stock,  cash  or  other  property  covered  by  such  Award,  the  Administrator  may  cancel  such  Award 
without  the  payment  of  any  consideration  to  the  Participant.  Except  to  the  extent  determined  by  the 
Administrator, any adjustments to ISOs under this Section 5 shall be made only to the extent not constituting a 
“modification”  within  the  meaning  of  Section 424(h)(3)  of  the  Code.  The  Administrator’s  determinations

Option  may  be  granted  to  the  same  Participant  and  be  outstanding  concurrently  hereunder.  Options  granted 
under  the  Plan  shall  be  subject  to  the  terms  and  conditions  set  forth  in  this  Section  7  and  shall  contain  such 
additional  terms  and  conditions,  not  inconsistent  with  the  terms  of  the  Plan,  as  the  Administrator  shall  deem 
desirable and set forth in the applicable Award Agreement. 

(b) 

Exercise  Price.  The  Exercise  Price  of  Shares  purchasable  under  an  Option  shall  be 
determined  by  the  Administrator  in  its  sole  discretion  at  the  time  of  grant,  but  in  no  event  shall  the  exercise 
price of an Option be less than one hundred percent (100%) of the Fair Market Value of a share of Common 
Stock on the date of grant. 

(c) 

Option  Term.  The  maximum  term  of  each  Option  shall  be  fixed  by  the 
Administrator, but no Option shall be exercisable more than ten (10) years after the date such Option is granted. 
Each  Option’s  term  is  subject  to  earlier  expiration  pursuant  to  the  applicable  provisions  in  the  Plan  and  the 
Award Agreement.  

(d) 

Exercisability. Each Option shall be exercisable at such time or times and subject to 
such  terms  and  conditions,  including  the  attainment  of  performance  goals,  as  shall  be  determined  by  the 
Administrator in the applicable Award Agreement. The Administrator may also provide that any Option shall be 
exercisable only in installments, and the Administrator may waive such installment exercise provisions at any 
time, in whole or in part, based on such factors as the Administrator may determine in its sole discretion. 

(e) 

Method of Exercise. Options may be exercised in whole or in part by giving written 
notice  of  exercise  to  the  Company  specifying  the  number  of  whole  Shares  to  be  purchased,  accompanied  by 
payment  in  full  of  the  aggregate  Exercise  Price  of  the  Shares  so  purchased  in  cash  or  its  equivalent,  as 
determined by the Administrator. As determined by the Administrator, in its sole discretion, with respect to any 
Option  or  category  of  Options,  payment  in  whole  or  in  part  may  also  be  made  (i) by  means  of  consideration 
received  under  any  cashless  exercise  procedure  approved  by  the  Administrator  (including  the  withholding  of 
Shares  otherwise  issuable  upon  exercise),  (ii) in  the  form  of  unrestricted  Shares  already  owned  by  the 
Participant which have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the 
Shares  as  to  which  such  Option  shall  be  exercised,  (iii) any  other  form  of  consideration  approved  by  the 
Administrator and permitted by Applicable Laws or (iv) any combination of the foregoing. 

(f) 

ISOs.  The  terms  and  conditions  of  ISOs  granted  hereunder  shall  be  subject  to  the 
provisions  of  Section  422  of  the  Code  and  the  terms,  conditions,  limitations  and  administrative  procedures 
established  by  the  Administrator  from  time  to  time  in  accordance  with  the  Plan.  At  the  discretion  of  the 
Administrator,  ISOs  may  be  granted  only  to  an  employee  of  the  Company,  its  “parent  corporation”  (as  such 
term is defined in Section 424(e) of the Code) or a Subsidiary of the Company. 

ISO Grants to 10% Shareholders. Notwithstanding anything to the contrary 
in the Plan, if an ISO is granted to a Participant who owns shares representing more than ten percent (10%) of 
the voting power of all classes of shares of the Company, its “parent corporation” (as such term is defined in 
Section 424(e) of the Code) or a Subsidiary of the Company, the term of the ISO shall not exceed five (5) years

of the Fair Market Value of the Shares on the date of grant. 

$100,000  Per  Year  Limitation  For  ISOs.  To  the  extent  the  aggregate  Fair 
Market Value (determined on the date of grant) of the Shares for which ISOs are exercisable for the first time 
by any Participant during any calendar year (under all plans of the Company) exceeds $100,000, such  excess 
ISOs shall be treated as Nonqualified Stock Options. 

(2) 

(3) 

Disqualifying Dispositions. Each Participant awarded an ISO under the Plan 
shall  notify  the  Company  in  writing  immediately  after  the  date  the  Participant  makes  a  “disqualifying 
disposition” of any Share acquired pursuant to the  exercise of such ISO.  A  “disqualifying disposition” is any 
disposition (including any sale) of such Shares before the later of (i) two years after the date of grant of the ISO 
and (ii) one year after the date the Participant acquired the Shares by exercising the ISO. The Company may, if 
determined by the Administrator and in accordance with procedures established by it, retain possession of any 
Shares acquired pursuant to the exercise of an ISO as agent for the applicable Participant until the end of the 
period described in the preceding sentence, subject to complying with any instructions from such Participant as 
to the sale of such Shares.

Rights  as  Shareholder.  A  Participant  shall  have  no  rights  to  dividends,  dividend 
equivalents or distributions or any other rights of a shareholder with respect to the Shares subject to an Option

employment status or service status of a Participant, in the discretion of the Administrator. 

Section 8. 

Share Appreciation Rights. 

(a) 

General.  Share  Appreciation  Rights  may  be  granted  either  alone  (“Free  Standing 
Rights”)  or  in  conjunction  with  all  or  part  of  any  Option  granted  under  the  Plan  (“Related  Rights”).  Related 
Rights may be granted either at or after the time of the grant of such Option. The Administrator shall determine 
the Eligible Recipients to whom, and the time or times at which, grants of Share Appreciation Rights shall be 
made. Each Participant who is granted a Share Appreciation Right shall enter into an Award Agreement with 
the Company, containing such terms and conditions as the Administrator shall determine, in its sole discretion, 
including, among other things, the number of Shares to be awarded, the Exercise Price per Share, and all other 
conditions of Share Appreciation Rights. Notwithstanding the foregoing, no Related Right may be granted for 
more Shares than are subject to the Option to which it relates. The provisions of Share Appreciation Rights need 
not  be  the  same  with  respect  to  each  Participant.  Share  Appreciation  Rights  granted  under  the  Plan  shall  be 
subject to the following terms and conditions set forth in this Section 8 and shall contain such additional terms 
and  conditions,  not  inconsistent  with  the  terms  of  the  Plan,  as  the  Administrator  shall  deem  desirable,  as  set 
forth in the applicable Award Agreement.

Appreciation  Right  until  the  Participant  has  given  written  notice  of  the  exercise  thereof  and  has  satisfied  the 
requirements of Section 15 hereof. 

(c) 

Exercise Price. The Exercise Price of Shares purchasable under a Share Appreciation 
Rights shall be determined by the Administrator in its sole discretion at the time of grant, but in no event shall 
the exercise price of a Share Appreciation Rights be less than one hundred percent (100%) of the Fair Market 
Value of a share of Common Stock on the date of grant.

of  the  date  of  exercise  over  the  Exercise  Price  specified  in  the  related  Option  multiplied  by  the  number  of

Section 9. 

Restricted Shares and Restricted Stock Units. 

(a) 

General. Restricted Shares or Restricted Stock Units may be issued under the Plan. 
The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, Restricted 
Shares or Restricted Stock Units shall be made. Each Participant who is granted Restricted Shares or Restricted 
Stock Units shall enter into an Award Agreement with the Company, containing such terms and conditions as 
the Administrator shall determine, in its sole discretion, including, among other things, the number of Shares to 
be awarded; the price, if any, to be paid by the Participant for the acquisition of Restricted Shares or Restricted 
Stock Units; the period of time restrictions, performance goals or other conditions that apply to Transferability, 
delivery  or  vesting  of  such  Awards  (the  “Restricted  Period”);  and  all  other  conditions  applicable  to  the 
Restricted Shares and Restricted Stock Units. If the restrictions, performance goals or conditions established by 
the  Administrator  are  not  attained,  a  Participant  shall  forfeit  his  or  her  Restricted  Shares  or  Restricted  Stock

Units,  in  accordance  with  the  terms  of  the  grant.  The  provisions  of  the  Restricted  Shares  or  Restricted  Stock 
Units need not be the same with respect to each Participant. 

(b) 

Awards  and  Certificates.  Except  as  otherwise  provided  below  in  Section  9(c), 
(i) each  Participant  who  is  granted  an  Award  of  Restricted  Shares  may,  in  the  Company’s  sole  discretion,  be 
issued  a  share  certificate  in  respect  of  such  Restricted  Shares;  and  (ii) any  such  certificate  so  issued  shall  be 
registered in the name of the Participant, and shall bear an appropriate legend referring to the terms, conditions 
and  restrictions  applicable  to  any  such  Award.  The  Company  may  require  that  the  share  certificates,  if  any, 
evidencing  Restricted  Shares  granted  hereunder  be  held  in  the  custody  of  the  Company  until  the  restrictions 
thereon shall have lapsed, and that, as a condition of any Award of Restricted Shares, the Participant shall have 
delivered a share transfer form, endorsed in blank, relating to  the Shares covered by such Award. Certificates 
for shares of unrestricted Common Stock may, in the Company’s sole discretion, be delivered to the Participant 
only after the Restricted Period has expired without forfeiture in such Restricted Stock Award. With respect to 
Restricted  Stock  Units  to  be  settled  in  Shares,  at  the  expiration  of  the  Restricted  Period,  share  certificates  in 
respect  of  the  shares  of  Common  Stock  underlying  such  Restricted  Stock  Units  may,  in  the  Company’s  sole 
discretion, be delivered to the Participant, or his legal representative, in a number equal to the number of shares 
of Common Stock  underlying the Restricted Stock Units  Award. Notwithstanding anything in the Plan to the 
contrary,  any  Restricted  Shares  or  Restricted  Stock  Units  to  be  settled  in  Shares  (at  the  expiration  of  the 
Restricted  Period,  and  whether  before  or  after  any  vesting  conditions  have  been  satisfied)  may,  in  the 
Company’s sole discretion, be issued in uncertificated form. Further, notwithstanding anything in the Plan to the 
contrary, with respect to Restricted Stock Units, at the expiration of the Restricted Period, Shares, or cash, as 
applicable,  shall  promptly  be  issued  (either  in  certificated  or  uncertificated  form)  to  the  Participant,  unless 
otherwise deferred in accordance with procedures established by the Company in accordance with Section 409A 
of the Code, and such issuance or payment shall in any event be made within such period as is required to avoid 
the imposition of a tax under Section 409A of the Code. 

(c) 

Restrictions and Conditions. The Restricted Shares or Restricted Stock Units granted 
pursuant  to  this  Section  9  shall  be  subject  to  the  following  restrictions  and  conditions  and  any  additional 
restrictions or conditions as determined by the Administrator at the time of grant or, subject to Section 409A of 
the Code where applicable, thereafter: 

The  Administrator  may,  in  its  sole  discretion,  provide  for  the  lapse  of 
restrictions in installments. Notwithstanding the foregoing, upon a Change in Control, the outstanding Awards 
shall be subject to Section 12 hereof.

(2) 

Except  as  provided  in  the  applicable  Award  Agreement,  the  Participant 
shall  generally  have  the  rights  of  a  shareholder  of  the  Company  with  respect  to  Restricted  Shares  during  the 
Restricted  Period;  provided, however,  that  dividends  declared  during  the  Restricted  Period  with  respect  to  an 
Award,  shall  only  become  payable  if  (and  to  the  extent)  the  underlying  Restricted  Shares  vest.  Except  as 
provided in the applicable Award Agreement, the Participant shall generally not have the rights of a shareholder 
with respect to Shares subject to Restricted Stock Units during the Restricted Period;  provided, however, that, 
subject to Section 409A of the Code, an amount equal to dividends declared during the Restricted Period with 
respect to the number of Shares covered by Restricted Stock Units shall, unless otherwise set forth in an Award 
Agreement, be paid to the Participant at the time (and to the extent) Shares in respect of the related Restricted 
Stock Units are delivered to the Participant. Certificates for Shares of unrestricted Common Stock may, in the 
Company’s sole discretion, be delivered to the Participant only after the Restricted Period has expired without 
forfeiture in respect of such Restricted Shares or Restricted Stock Units, except as the Administrator, in its sole 
discretion, shall otherwise determine. 

The  rights  of  Participants  granted  Restricted  Shares  or  Restricted  Stock 
Units upon termination of employment with the Company or to any Affiliate thereof terminates for any reason 
during the Restricted Period shall be set forth in the Award Agreement. 

(3) 

Form  of  Settlement.  The  Administrator  reserves  the  right  in  its  sole  discretion  to 
provide  (either  at  or  after  the  grant  thereof)  that  any  Restricted  Stock  Unit  represent  the  right  to  receive  the 
amount of cash per unit that is determined by the Administrator in connection with the Award.

Other Share-Based Awards. 

Other  Share-Based  Awards  may  be  issued  under  the  Plan.  Subject  to  the  provisions  of  the 
Plan, the  Administrator shall  have sole and complete authority to determine the individuals to  whom and the 
time  or  times  at  which  such  Other  Share-Based  Awards  shall  be  granted.  Each  Participant  who  is  granted  an 
Other Share-Based Award shall enter into an Award Agreement with the Company, containing such terms and 
conditions  as  the  Administrator  shall  determine,  in  its  sole  discretion,  including,  among  other  things,  the 
number of shares of Common Stock to be granted pursuant to such Other Share-Based Awards, or the manner 
in  which  such  Other  Share-Based  Awards  shall  be  settled  (e.g.,  in  shares  of  Common  Stock,  cash  or  other 
property),  or  the  conditions  to  the  vesting  and/or  payment  or  settlement  of  such  Other  Share-Based  Awards 
(which  may  include,  but  not  be  limited  to,  achievement  of  performance  criteria)  and  all  other  terms  and 
conditions of such Other Share-Based Awards. In the event that the Administrator grants a bonus in the form of 
Shares,  the  Shares  constituting  such  bonus  shall,  as  determined  by  the  Administrator,  be  evidenced  in 
uncertificated form or by a book entry record or a certificate issued in the name of the Participant to whom such 
grant was made and delivered to such Participant as soon as practicable after the date on which such bonus is 
payable.  Notwithstanding  anything  set  forth  in  the  Plan  to  the  contrary,  any  dividend  or  dividend  equivalent 
Award issued hereunder shall be subject to the same restrictions, conditions and risks of forfeiture as apply to 
the underlying Award. 

Section 11. 

Change in Control. 

Unless  otherwise  determined  by  the  Administrator  and  evidenced  in  an  Award  Agreement, 
notwithstanding  Section 4(e)  of  the  Plan,  in  the  event  that  (a) a  Change  in  Control  occurs,  and  (b)  the 
Participant is employed by the Company or any of its Affiliates immediately prior to the consummation of such

applicable to an Award granted under the Plan shall lapse and such Awards shall be deemed fully vested and 
any performance conditions imposed with respect to such Awards shall be deemed to be fully achieved at target 
performance levels. 

The Administrator shall have discretion in connection with such Change in Control to provide 
that  all  Options  and/or  Share  Appreciation  Rights  outstanding  immediately  prior  to  such  Change  in  Control 
shall expire upon the consummation of such Change in Control if not exercised upon, or prior to, such Change 
in Control.  

Section 12. 

Amendment and Termination. 

The Board may amend, alter or terminate the Plan at any time, but no amendment, alteration 
or termination shall be made that would impair the rights of a Participant under any Award theretofore granted 
without  such  Participant’s  consent.  The  Board  shall  obtain  approval  of  the  Company’s  shareholders  for  any 
amendment  that  would  require  such  approval  in  order  to  satisfy  the  requirements  of  any  rules  of  the  stock 
exchange  on  which  the  Common  Stock  is  traded  or  other  Applicable  Law.  Subject  to  Section  3(c),  the 
Administrator  may  amend  the  terms  of  any  Award  theretofore  granted,  prospectively  or  retroactively,  but, 
subject to Section 5 of the Plan and the immediately preceding sentence, no such amendment shall materially 
impair the rights of any Participant without his or her consent. 

Section 13. 

Unfunded Status of Plan. 

The  Plan  is  intended  to  constitute  an  “unfunded”  plan  for  incentive  compensation.  With 
respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any 
such Participant any rights that are greater than those of a general creditor of the Company.

Withholding Taxes. 

Each Participant shall, no later than the date as of which the value of an Award first becomes 
includible  in  the  gross  income  of  such  Participant  for  purposes  of  applicable  taxes,  pay  to  the  Company,  or 
make  arrangements  satisfactory  to  the  Administrator  regarding  payment  of  an  amount  up  to  the  maximum 
statutory tax rates in the Participant’s applicable jurisdiction  with respect to the  Award, as determined by the 
Company. The obligations of the Company under the Plan shall be conditional on the making of such payments 
or arrangements, and the Company shall, to the extent permitted by Applicable Laws, have the right to deduct 
any such taxes from any payment of any kind otherwise due to such Participant. Whenever cash is to be paid 
pursuant to an Award, the Company shall have the right to deduct therefrom an amount sufficient to satisfy any 
applicable withholding tax requirements related thereto. Whenever Shares or property other than cash are to be 
delivered  pursuant  to  an  Award,  the  Company  shall  have  the  right  to  require  the  Participant  to  remit  to  the 
Company  in  cash  an  amount  sufficient  to  satisfy  any  related  taxes  to  be  withheld  and  applied  to  the  tax 
obligations;  provided,  that,  with  the  approval  of  the  Administrator,  a  Participant  may  satisfy  the  foregoing 
requirement by either (i) electing to have the Company withhold from delivery of Shares or other property, as 
applicable, or (ii) delivering already owned unrestricted shares of Common Stock, in each case, having a value 
not exceeding the applicable taxes to be withheld and applied to the tax obligations. Such already owned and 
unrestricted  shares  of  Common  Stock  shall  be  valued  at  their  Fair  Market  Value  on  the  date  on  which  the 
amount of tax to be withheld is determined and any fractional share amounts resulting therefrom shall be settled 
in cash. Such an election may be made with respect to all or any portion of the Shares to be delivered pursuant 
to an award. The Company may also use any other method of obtaining the necessary payment or proceeds, as 
permitted by Applicable Laws, to satisfy its withholding obligation with respect to any Award. 

Section 15. 

Transfer of Awards. 

Until such time as the Awards are fully vested and/or exercisable in accordance with the Plan 
or  an  Award  Agreement,  no  purported  sale,  assignment,  mortgage,  hypothecation,  transfer,  charge,  pledge, 
encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in 
or lien on, any Award or any agreement or commitment to do any of the foregoing (each, a “Transfer”) by any 
holder thereof in violation of the provisions of the Plan or an Award Agreement will be valid, except with the 
prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of 
the Administrator. Any purported Transfer of an Award or any economic benefit or interest therein in violation 
of  the  Plan  or  an  Award  Agreement  shall  be  null  and  void  ab  initio  and  shall  not  create  any  obligation  or 
liability of the Company, and any Person purportedly acquiring any Award or any economic benefit or interest 
therein transferred in violation of the Plan or an Award Agreement shall not be entitled to be recognized as a 
holder  of  such  Shares  or  other  property  underlying  such  Award.  Unless  otherwise  determined  by  the 
Administrator in accordance with the provisions of the immediately preceding sentence, an Option or a Share 
Appreciation Right may be exercised, during the lifetime of the Participant, only by the Participant or, during 
any  period  during  which  the  Participant  is  under  a  legal  Disability,  by  the  Participant’s  guardian  or  legal 
representative. 

Section 16. 

Continued Employment or Service. 

Neither  the  adoption  of  the  Plan  nor  the  grant  of  an  Award  shall  confer  upon  any  Eligible 
Recipient any right to continued employment or service with the Company or any Affiliate thereof, as the case 
may be, nor shall it interfere in any way with the right of the Company or any Affiliate thereof to terminate the 
employment or service of any of its Eligible Recipients at any time.

Securities Matters and Regulations. 

(a) 

Notwithstanding  anything  herein  to  the  contrary,  the  obligation  of  the  Company  to 
sell or deliver Shares with respect to any Award granted under the Plan shall be subject to all Applicable Laws, 
rules  and  regulations,  including  all  applicable  federal  and  state  securities  laws,  and  the  obtaining  of  all  such 
approvals  by  governmental  agencies  as  may  be  deemed  necessary  or  appropriate  by  the  Administrator.  The 
Administrator  may  require,  as  a  condition  of  the  issuance  and  delivery  of  certificates  evidencing  shares  of 
Common  Stock  pursuant  to  the  terms  hereof,  that  the  recipient  of  such  shares  make  such  agreements  and 
representations, and that such certificates bear such legends, as the Administrator, in its sole discretion, deems 
necessary or advisable. 

(b) 

Each  Award  is  subject  to  the  requirement  that,  if  at  any  time  the  Administrator 
determines that the listing, registration or qualification of Shares is required by any securities exchange or under 
any  state  or  federal  law,  or  the  consent  or  approval  of  any  governmental  regulatory  body  is  necessary  or 
desirable  as  a  condition  of,  or  in  connection  with,  the  grant  of  an  Award  or  the  issuance  of  Shares,  no  such 
Award  shall  be  granted  or  payment  made  or  Shares  issued,  in  whole  or  in  part,  unless  listing,  registration, 
qualification,  consent  or  approval  has  been  effected  or  obtained  free  of  any  conditions  not  acceptable  to  the 
Administrator. 

(c) 

In  the  event  that  the  disposition  of  Shares  acquired  pursuant  to  the  Plan  is  not 
covered by a then current registration statement under the Securities Act and is not otherwise exempt from such 
registration,  such  Shares  shall  be  restricted  against  transfer  to  the  extent  required  by  the  Securities  Act  or 
regulations thereunder, and the Administrator  may require a Participant receiving Common Stock pursuant to 
the Plan, as a condition precedent to receipt of such Common Stock, to represent to the Company in writing that 
the  Common  Stock  acquired  by  such  Participant  is  acquired  for  investment  only  and  not  with  a  view  to 
distribution. 

Section 21. 

Section 409A of the Code. 

The Plan as well as payments and benefits under the Plan are intended to be exempt from, or 
to  the  extent  subject  thereto,  to  comply  with  Section 409A  of  the  Code,  and,  accordingly,  to  the  maximum 
extent  permitted,  the  Plan  shall  be  interpreted  in  accordance  therewith.  Notwithstanding  anything  contained 
herein to the contrary, to the  extent required in order to avoid accelerated taxation and/or tax penalties  under 
Section 409A  of  the  Code,  the  Participant  shall  not  be  considered  to  have  terminated  employment  or  service 
with the Company for purposes of the Plan and no payment shall be due to the Participant under the Plan or any 
Award  until  the  Participant  would  be  considered  to  have  incurred  a  “separation  from  service”  from  the 
Company and its  Affiliates  within the  meaning of Section 409A of the  Code. Any payments described in the 
Plan that are  due  within the  “short term deferral period” as defined in Section 409A of the Code shall  not be 
treated  as  deferred  compensation  unless  Applicable  Law  requires  otherwise.  Notwithstanding  anything  to  the 
contrary in the Plan, to the extent that any Awards (or any other amounts payable under any plan, program or 
arrangement  of  the  Company  or  any  of  its  Affiliates)  are  payable  upon  a  separation  from  service  and  such 
payment  would  result  in  the  imposition  of  any  individual  tax  and  penalty  interest  charges  imposed  under 
Section 409A of the Code, the settlement and payment of such awards (or other amounts) shall instead be made 
on the first business day after the date that is six (6) months following such separation from service (or death, if 
earlier).  Each  amount  to  be  paid  or  benefit  to  be  provided  under  this  Plan  shall  be  construed  as  a  separate 
identified payment for purposes of Section 409A of the Code. The Company makes no representation that any 
or all of the payments or benefits described in this Plan will be exempt from or comply with Section 409A of 
the Code and makes no undertaking to preclude Section 409A of the Code from applying to any such payment. 
The  Participant  shall  be  solely  responsible  for  the  payment  of  any  taxes  and  penalties  incurred  under 
Section 409A.

Section 22. 

Notification of Election Under Section 83(b) of the Code. 

If any Participant shall, in connection with the acquisition of shares of Common Stock under 
the  Plan,  make  the  election  permitted  under  Section 83(b)  of  the  Code,  such  Participant  shall  notify  the 
Company  of  such  election  within  ten (10)  days  after  filing  notice  of  the  election  with  the  Internal  Revenue 
Service. 

Section 23. 

No Fractional Shares. 

No fractional shares of Common Stock shall be issued or delivered pursuant to the Plan. The 
Administrator shall determine whether cash, other Awards, or other property shall be issued or paid in lieu of 
such  fractional  shares  or  whether  such  fractional  shares  or  any  rights  thereto  shall  be  forfeited  or  otherwise 
eliminated. 

Section 24. 

Beneficiary. 

A Participant may file with the Administrator a written designation of a beneficiary on such 
form as may be prescribed by the Administrator and may, from time to time, amend or revoke such designation. 
If  no  designated  beneficiary  survives  the  Participant,  the  executor  or  administrator  of  the  Participant’s  estate 
shall be deemed to be the Participant’s beneficiary. 

Section 25. 

Paperless Administration. 

In the event that the Company establishes, for itself or using the services of a third party, an 
automated  system  for  the  documentation,  granting  or  exercise  of  Awards,  such  as  a  system  using  an  internet 
website or interactive  voice  response, then the paperless documentation,  granting or exercise of  Awards by a 
Participant may be permitted through the use of such an automated system. 

Section 26. 

Severability. 

If any provision of the Plan is held to be invalid or unenforceable, the other provisions of the 
Plan shall not be affected but shall be applied as if the invalid or unenforceable provision had not been included 
in the Plan. 

Section 27. 

Clawback. 

(a) 

If the Company is required to prepare a financial restatement due to the material non-
compliance  of  the  Company  with  any  financial  reporting  requirement,  then  the  Committee  may  require  any 
Section 16 Officer to repay or forfeit to the Company, and each Section 16 Officer agrees to so repay or forfeit, 
that  part  of  the  Incentive  Compensation  received  by  that  Section 16  Officer  during  the  three-year  period 
preceding the publication of the restated financial statement that the Committee determines was in excess of the 
amount  that  such  Section 16  Officer  would  have  received  had  such  Incentive  Compensation  been  calculated 
based on the financial results reported in the restated financial statement. The Committee may take into account 
any  factors  it  deems  reasonable  in  determining  whether  to  seek  recoupment  of  previously  paid  Incentive 
Compensation and how much Incentive Compensation to recoup from each Section 16 Officer (which need not 
be the same amount or proportion for each Section 16 Officer), including any determination by the Committee 
that a Section 16 Officer engaged in fraud, willful misconduct or committed grossly negligent acts or omissions 
which  materially  contributed  to  the  events  that  led  to  the  financial  restatement.  The  amount  and  form  of  the 
Incentive  Compensation  to  be  recouped  shall  be  determined  by  the  Committee  in  its  sole  and  absolute 
discretion,  and  recoupment  of  Incentive  Compensation  may  be  made,  in  the  Committee’s  sole  and  absolute 
discretion, through the cancellation of vested or unvested Awards, cash repayment or both. 

Notwithstanding  any  other  provisions  in  this  Plan,  any  Award  which  is  subject  to 
recovery  under  any  Applicable  Laws,  government  regulation  or  stock  exchange  listing  requirement,  will  be 
subject  to  such  deductions  and  clawback  as  may  be  required  to  be  made  pursuant  to  such  Applicable  Law,

Company.

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  loan  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,  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  economic  performance;  and 
(iv) statements  of  assumptions  underlying  such  statements.    Words  such  as  "believes",  "anticipates",  "expects",  “estimates”, 
"intends",  "targeted",  "projected",  “forecast”,  "continue",  "remain",  "will",  "should",  "may"  and  other  similar  expressions  are 
intended to identify forward-looking statements but are not the exclusive means of identifying such statements. 

These forward-looking statements are based on Management’s current knowledge and belief 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 terrorist threats and attacks on the United States, the actions taken in 
response,  and  the  uncertain  effect  of  these  events  on  the  national  and  regional  economies;  (6)  changes  in  the  interest  rate 
environment; (7) changes in the regulatory environment; (8) competitive pressure  in the  banking industry; (9) operational risks 
including a  failure or breach in data processing or security systems or those of third party vendors and other service  providers, 
including  as  a  result  of  cyber  attacks  or  fraud;  (10)  volatility  of  interest  rate  sensitive  loans,  deposits  and  investments;  (11) 
asset/liability  management  risks  and  liquidity  risks;  (12)  the  effect  of  natural  disasters,  including  earthquakes,  hurricanes,  fire, 
flood, drought, and other disasters, on the uninsured value of the Company’s assets and of loan collateral, the financial condition 
of debtors and issuers of investment securities, the economic conditions affecting the Company’s market place, and commodities 
and  asset  values;  (13)  changes  in  the  securities  markets  and  (14)  the  outcome  of  contingencies,  such  as  legal  proceedings. 
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. See also “Risk Factors” in Item 1A and other risk factors discussed elsewhere 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. Principal 
administrative offices are located at 4550 Mangels Boulevard, Fairfield, California 94534 and its telephone number is (707) 863-
6000. The Company provides a full range of banking services to individual and  commercial customers in Northern and Central 
California through its subsidiary bank, Westamerica Bank (“WAB” or the “Bank”). The principal communities served are located 
in Northern and Central California, from Mendocino, Lake and Nevada Counties in the  north to Kern County in the  south. The 
Company’s strategic focus is on the banking needs of small businesses. In addition, the Bank owns 100% of the capital stock of 
Community Banker Services Corporation (“CBSC”), a company engaged in providing the Company and its subsidiaries with data 
processing services and other support functions. 

The  Company  was  incorporated  under  the  laws  of  the  State  of  California  in  1972  as  “Independent  Bankshares  Corporation” 
pursuant to a plan of reorganization among three previously unaffiliated Northern California banks. The Company operated as a 
multi-bank holding company until mid-1983, at which time the then six subsidiary banks were merged into a single bank named 
Westamerica Bank and the name of the holding company was changed to Westamerica Bancorporation. 

The Company acquired five banks within its immediate market area during the early to mid 1990’s. In April 1997, the Company 
acquired  ValliCorp  Holdings,  Inc.,  parent  company  of  ValliWide  Bank,  the  largest  independent  bank  holding  company

headquartered in Central California. Under the terms of all of the merger agreements, the Company issued shares of its common 
stock in exchange for all of the outstanding shares of the acquired institutions. The subsidiary banks acquired were merged with 
and into WAB. These six aforementioned business combinations were accounted for as poolings-of-interests. 

During the period 2000 through 2005, the Company acquired three additional banks. These acquisitions were accounted for using 
the purchase accounting method. 

On February 6, 2009, Westamerica Bank acquired the banking operations of County Bank (“County”) from the Federal Deposit 
Insurance Corporation (“FDIC”).  On August 20, 2010,  Westamerica Bank acquired assets and assumed liabilities of the former 
Sonoma  Valley  Bank  (“Sonoma”)  from  the  FDIC.  The  County  and  Sonoma  acquired  assets  and  assumed  liabilities  were 
measured at estimated fair values, as required by FASB ASC 805, Business Combinations.  

At  December  31,  2018,  the  Company  had  consolidated  assets  of  approximately  $5.6  billion,  deposits  of  approximately  $4.9 
billion  and  shareholders’  equity  of  approximately  $616  million.  The  Company  and  its  subsidiaries  employed  762  full-time 
equivalent staff as of December 31, 2018. 

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:

Supervision and Regulation 

The following is not intended to be an exhaustive description of the statutes and regulations applicable to the Company’s or the 
Bank’s business. The description of statutory and regulatory provisions is qualified in its entirety by reference to the particular 
statutory  or  regulatory  provisions.  Moreover,  major  new  legislation  and  other  regulatory  changes  affecting  the  Company,  the 
Bank, and the financial services industry in general have occurred in the last several years and can be expected to occur in  the 
future. The nature, timing and impact of new and amended laws and regulations cannot be accurately predicted. 

Regulation and Supervision of Bank Holding Companies  

The  Company  is  a  bank  holding  company  subject  to  the  BHCA.  The  Company  reports  to,  is  registered  with,  and  may  be 
examined by, the Board of Governors of the Federal Reserve System (“FRB”). The FRB also has the authority to examine the 
Company’s subsidiaries. The Company is a bank holding company within the meaning of Section 3700 of the California Financial 
Code.  As  such,  the  Company  and  the  Bank  are  subject  to  examination  by,  and  may  be  required  to  file  reports  with,  the 
Commissioner of the California Department of Business Oversight (the “Commissioner”). 

The FRB has significant supervisory and regulatory authority over the Company and its affiliates. The FRB requires the Company 
to maintain certain levels of capital. See “Capital Standards.” The FRB also has the authority to take enforcement action against 
any  bank  holding  company  that  commits  any  unsafe  or  unsound  practice,  or  violates  certain  laws,  regulations  or  conditions 
imposed  in  writing  by  the  FRB.  Under  the  BHCA,  the  Company  is  required  to  obtain  the  prior  approval  of  the  FRB  before  it 
acquires, merges or consolidates with any bank or bank holding company. Any company seeking to acquire, merge or consolidate 
with the Company also would be required to obtain the prior approval of the FRB. 

The  Company  is  generally  prohibited  under  the  BHCA  from  acquiring  ownership  or  control  of  more  than  5%  of  any  class  of 
voting shares of any company that is not a bank or bank holding company and from engaging directly or indirectly in activities 
other  than  banking,  managing  banks,  or  providing  services  to  affiliates  of  the  holding  company.  However,  a  bank  holding 
company,  with the approval of the FRB,  may engage, or acquire  the  voting shares of companies engaged, in activities that the 
FRB  has  determined  to  be  closely  related  to  banking  or  managing  or  controlling  banks.  A  bank  holding  company  must 
demonstrate that the benefits to the public of the proposed activity will outweigh the possible adverse effects associated with such 
activity.

2018      WESTAMERICA BANCORPORATION FORM 10-K 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 Regulation W. The regulation codifies prior interpretations 
of  the  FRB  and  its  staff  under  Sections  23A  and  23B  of  the  Federal  Reserve  Act.  In  general,  subject  to  certain  specified 
exemptions,  a  bank  or  its  subsidiaries  are  limited  in  their  ability  to  engage  in  “covered  transactions”  with  affiliates:  (a)  to  an 
amount equal to 10% of the bank’s capital and surplus, in the case of covered transactions with any one affiliate; and (b) to an 
amount equal to 20% of the  bank’s capital and surplus, in the case  of covered transactions  with all affiliates. The  Company is 
considered to be an affiliate of the Bank. A “covered transaction” includes, among other things, a loan or extension of credit to an 
affiliate;  a  purchase  of  securities  issued  by  an  affiliate;  a  purchase  of  assets  from  an  affiliate,  with  some  exceptions;  and  the 
issuance of a guarantee, acceptance or letter of credit on behalf of an affiliate. 

Federal regulations governing bank holding companies and change in bank control (Regulation Y) provide for a streamlined and 
expedited  review  process  for  bank  acquisition  proposals  submitted  by  well-run  bank  holding  companies.  These  provisions  of 
Regulation Y are subject to numerous qualifications, limitations and restrictions. In order for a bank holding company to qualify 
as  “well-run,”  both  it  and  the  insured  depository  institutions  which  it  controls  must  meet  the  “well  capitalized”  and  “well 
managed” criteria set forth in Regulation Y. 

The  Gramm-Leach-Bliley  Act  (the  “GLBA”),  or  the  Financial  Services  Act  of  1999,  repealed  provisions  of  the  Glass-Steagall 
Act, which had prohibited  commercial banks and securities firms from affiliating with each other and engaging in each other’s 
businesses.  Thus,  many  of  the  barriers  prohibiting  affiliations  between  commercial  banks  and  securities  firms  have  been 
eliminated. 

The BHCA was also amended by the GLBA to allow new “financial holding companies” (“FHCs”) to offer banking, insurance, 
securities and other financial products to consumers. Specifically, the GLBA amended section 4 of the BHCA in order to provide 
for a framework for the engagement in new financial activities. A bank holding company (“BHC”) may elect to become an FHC 
if all its subsidiary depository institutions are well capitalized and well managed. If these requirements are met, a BHC may file a 
certification  to  that  effect  with  the  FRB  and  declare  that  it  elects  to  become  an  FHC.  After  the  certification  and  declaration  is 
filed, the FHC may engage either de novo or through an acquisition in any activity that has been determined by the FRB to be 
financial in nature or incidental to such financial activity. BHCs may engage in financial activities without prior notice to the FRB 
if those activities qualify under the list of permissible activities in section 4(k) of the BHCA. However, notice must be given to 
the FRB within 30 days after an FHC has commenced one or more of the financial activities. The Company has not elected to 
become an FHC. 

Regulation and Supervision of Banks 

The  Bank  is  a  California  state-chartered  Federal  Reserve  member  bank  and  its  deposits  are  insured  by  the  FDIC.  The  Bank  is 
subject to regulation, supervision and regular examination by the California Department of Business Oversight (“DBO”) and the 
FRB. The regulations of these agencies affect most aspects of the Bank’s business and prescribe permissible types  of loans and 
investments, the amount of required reserves, requirements for branch offices, the permissible scope of its activities and various 
other requirements. 

In addition to federal banking law, the Bank is also subject to applicable provisions of California law. Under California law, the 
Bank is subject to various restrictions on, and requirements regarding, its operations and administration including the maintenance 
of branch offices and automated teller machines, capital requirements, deposits and borrowings, shareholder rights and duties, and 
investment and lending activities. 

In addition, the Federal Deposit Insurance Corporation Improvement  Act (“FDICIA”) imposes limitations on the activities and 
equity investments of state chartered, federally insured banks. FDICIA also prohibits a state bank from making an investment or 
engaging in any activity as a principal that is not permissible for a national bank, unless the Bank is adequately capitalized and the 
FDIC approves the investment or activity after determining that such investment or activity does not pose a significant risk to the 
deposit insurance fund.

On July 21, 2010, financial regulatory reform legislation entitled the "Dodd-Frank Wall Street Reform and Consumer Protection 
Act" (the "Dodd-Frank Act") was signed into law. The Dodd-Frank Act implemented far-reaching changes across the financial 
regulatory landscape, including provisions that, among other things: 

  Centralized  responsibility  for  consumer  financial  protection  by  creating  a  new  agency,  the  Consumer  Financial 
Protection  Bureau,  responsible  for  implementing,  examining  and  (as  to  banks  with  $10  billion  or  more  in  assets) 
enforcing compliance with federal consumer financial laws. 

  Restricted the preemption of state law by federal law  and disallowed subsidiaries and affiliates of national banks from 

availing themselves of such preemption. 

  Applied  the  same  leverage  and  risk-based  capital  requirements  that  would  apply  to  insured  depository  institutions  to 

most bank holding companies. 

  Required bank regulatory agencies to seek to  make  their capital requirements  for banks countercyclical so that capital 

requirements increase in times of economic expansion and decrease in times of economic contraction. 

  Changed the assessment base for federal deposit insurance from the amount of insured deposits to consolidated assets 
less tangible capital, eliminated the ceiling on the size of the Deposit Insurance Fund ("DIF") and increased the floor of 
the size of the DIF. 
Imposed comprehensive regulation of  the over-the-counter derivatives  market,  which  would include certain provisions 
that  would  effectively  prohibit  insured  depository  institutions  from  conducting  certain  derivatives  businesses  in  the 
institution itself. 

 

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

 

enterprise risk management. 
Implemented  corporate  governance  revisions,  including  with  regard  to  executive  compensation  and  proxy  access  by 
shareholders, that would apply to all public companies, not just financial institutions. 

  Made permanent the $250 thousand limit for federal deposit insurance. 
  Repealed  the  federal  prohibitions  on  the  payment  of  interest  on  demand  deposits,  thereby  permitting  depository 

institutions to pay interest on business transaction and other accounts. 

  Amended  the  Electronic  Fund Transfer  Act  ("EFTA")  to, among  other  things,  give  the  FRB  the  authority  to  establish 
rules regarding interchange fees charged for electronic debit transactions by payment card issuers having assets over $10 
billion and to enforce a new statutory requirement that such fees be reasonable and proportional to the actual cost of a 
transaction  to  the  issuer.  While  the  Company’s  assets  are  currently  less  than  $10  billion,  interchange  fees  charged  by 
larger institutions may dictate the level of fees smaller institutions will be able to charge to remain competitive. 

Provisions in the legislation that affect the payment of interest on demand deposits and interchange fees  may increase the costs 
associated with deposits as well as place limitations on certain revenues those deposits may generate.  

Capital Standards  

The federal banking agencies have risk-based capital adequacy guidelines intended to provide a measure of capital adequacy that 
reflects  the  degree  of  risk  associated  with  a  banking  organization’s  operations  for  both  transactions  resulting  in  assets  being 
recognized on the balance sheet as assets, and the extension of credit facilities such as letters of credit and recourse arrangements, 
which  are  recorded  as  off  balance  sheet  items.  Under  these  guidelines,  nominal  dollar  amounts  of  assets  and  credit  equivalent 
amounts of off balance sheet items are multiplied by one of several risk adjustment percentages, which range from 0% for assets 
with  low credit risk, such as  certain U.S.  government securities, to 1250% for assets  with relatively  higher credit risk, such as 
certain securitizations. A banking organization’s risk-based capital ratios are obtained by dividing its qualifying capital by its total 
risk-adjusted assets and off balance sheet items. 

The federal banking agencies take into consideration concentrations of credit risk and risks from nontraditional activities,  as well 
as  an  institution’s  ability  to  manage  those  risks,  when  determining  the  adequacy  of  an  institution’s  capital.  This  evaluation  is 
made as a part of the institution’s regular safety and soundness examination. The federal banking agencies also consider interest 
rate  risk  (related  to  the  interest  rate  sensitivity  of  an  institution’s  assets  and  liabilities,  and  its  off  balance  sheet  financial 
instruments) in the evaluation of a bank’s capital adequacy. 

As  of  December  31,  2018,  the  Company’s  and  the  Bank’s  respective  ratios  exceeded  applicable  regulatory  requirements.  See 
Note  9 to the consolidated  financial statements  for capital ratios of the Company and the  Bank, compared to  minimum capital 
requirements and for the Bank the standards for well capitalized depository institutions.

On July 2, 2013, the Federal Reserve Board approved a final rule that implements changes to the regulatory capital framework for 
all banking organizations over a transitional period 2015 through 2018. 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 

Substantially all of the deposits of the Bank are insured up to applicable limits by the DIF of the FDIC and are subject to deposit 
insurance assessments to maintain the DIF. The FDIC utilizes a risk-based assessment system that imposes insurance premiums 
based upon a risk matrix that takes into account a bank's capital level, asset quality and supervisory rating ("CAMELS rating"). 

In July 2010, Congress in the Dodd-Frank Act increased the minimum for  the DIF reserve ratio, the ratio of the amount in the 
fund to insured deposits, from 1.15% to 1.35% and required that the ratio reach that level by September 30, 2020.  Further, the 
Dodd-Frank Act made banks with $10 billion or more in assets responsible for the increase from 1.15% to 1.35%, among other 
provisions. 

In  October  2010,  the  FDIC  adopted  a  new  DIF  restoration  plan  to  ensure  the  DIF  reaching  1.35%  by  September  30,  2020.  In 
assessing its progress in restoring the reserves, at least semi-annually, the FDIC updates its loss and income projections for the 
fund and, if needed, increases or decreases assessment rates, following notice-and-comment rulemaking, if required. 

In February 2011, the FDIC adopted a final rule effective April 1, 2011 to: 

(1)  Redefine the deposit insurance assessment base from total domestic deposits to average total assets minus average 

tangible equity as required by the Dodd-Frank Act; 

(2)  Change  the  deposit  insurance  assessment  rates  (which  provide  for  progressively  lower  assessment  rate  schedules 

that will take effect when the reserve ratio exceeds 1.15%, 2%, and 2.5%) ; 

(3)  Implement the Dodd-Frank Act DIF dividend provisions; and 
(4)  Revise  the  risk-based  assessment  system  for  all  “large”  and  “highly  complex”  insured  depository  institutions.  
“Large” depository institutions are defined generally as having more than $10 billion in assets and "highly complex" 
institutions  have  over  $50  billion  in  assets  and  are  fully  owned  by  a  parent  with  over  $500 billion  in  assets.  The 
Bank is neither a “large” nor “highly complex” institution.  

In March, 2016, the FDIC issued a final rule to increase the DIF reserve ratio to the statutory minimum level of 1.35%, effective 
July 1, 2016, if the reserve ratio reached 1.15% before that date. 

In  August,  2016,  the  FDIC  announced  the  DIF  reserve  ratio  surpassed  the  1.15%  reserve  ratio  target,  triggering  three  major 
changes: 

(1)  The decline in the range of initial assessment rates for all banks from 5-35 basis points to 3-30 basis points; 
(2)  The  assessment  of  a  quarterly  surcharge  on  large  banks  equal  to  an  annual  rate  of  4.5  basis  points  in  addition  to 

regular assessments; and  

(3)  A revised  method to calculate risk-based assessment rates for established small banks (under $1 billion in assets) 

pursuant to an FDIC final rule issued April, 2016. 

In  September  2018,  the  FDIC  issued  a  Financial  Institutions  Letter  stating  the  Deposit  Insurance  Fund  Reserve  Ratio  reached 
1.36%, exceeding the statutorily required minimum reserve ratio of 1.35% ahead of the  September 30, 2020, deadline required 
under  the  Dodd-Frank  Act.  FDIC  regulations  provide  for  two  changes  to  deposit  insurance  assessments  upon  reaching  the 
minimum: (1) surcharges on insured depository institutions with total consolidated assets of $10 billion or more (large banks) will 
cease; and (2) small banks will receive assessment credits for the portion of their assessments that contributed to the growth in the 
reserve  ratio  from between 1.15% and 1.35%, to be applied  when the reserve ratio is at or above 1.38%. In January  2019, the 
Bank, which meets the definition of a “small Bank”, was advised by the FDIC its assessment credit to be applied when the reserve 
ratio  is  at  or  above  1.38%  is  $1.4  million  which  will  reduce  future  assessment  expenses.  The  Company  cannot  provide  any 
assurance as to the effect of any future changes in its deposit insurance premium rates.

Community Reinvestment Act and Fair Lending Developments 

The Bank is subject to certain fair lending requirements and reporting obligations involving home mortgage lending operations 
and Community Reinvestment Act (“CRA”) activities. The CRA generally requires the federal banking agencies to evaluate the 
record  of  financial  institutions  in  meeting  the  credit  needs  of  their  local  communities,  including  low  and  moderate  income 
neighborhoods. In addition to substantive penalties and corrective  measures that  may be required for a violation of certain  fair 
lending  laws,  the  federal  banking  agencies  may  take  compliance  with  such  laws  and  CRA  into  account  when  regulating  and 
supervising other activities including merger applications. 

Financial Privacy Legislation and Customer Information Security  

The GLBA, in addition to the previously described changes in permissible nonbanking activities permitted to banks, BHCs and 
FHCs,  also  required  the  federal  banking  agencies,  among  other  federal  regulatory  agencies,  to  adopt  regulations  governing  the 
privacy of consumer financial information. The Bank is subject to the FRB’s regulations in this area. The federal bank regulatory 
agencies have established standards for safeguarding nonpublic personal information about customers that implement provisions 
of the GLBA (the “Guidelines”). Among other things, the Guidelines require each financial institution, under the supervision and 
ongoing  oversight  of  its  Board  of  Directors  or  an  appropriate  committee  thereof,  to  develop,  implement  and  maintain  a 
comprehensive written information security program designed to ensure the security and confidentiality of customer information, 
to  protect  against  any  anticipated  threats  or  hazards  to  the  security  or  integrity  of  such  information,  and  to  protect  against 
unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer. 

U.S.A. PATRIOT Act  

Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism 
Act of 2001 (“USA Patriot Act”) is the International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001. It 
includes  numerous  provisions  for  fighting  international  money  laundering  and  blocking  terrorist  access  to  the  U.S.  financial 
system. The goal of Title III is to prevent the U.S. financial system and the U.S. clearing mechanisms from being used by parties 
suspected of terrorism, terrorist financing and money laundering. The provisions of Title III of the USA Patriot Act which affect 
the  Bank  are  generally  set  forth  as  amendments  to  the  Bank  Secrecy  Act.  These  provisions  relate  principally  to  U.S.  banking 
organizations’ relationships with foreign banks and with persons who are resident outside the United States. The USA Patriot Act 
does not impose any  filing or reporting obligations  for banking organizations, but does require  certain additional due diligence 
and recordkeeping practices. 

Sarbanes-Oxley Act of 2002  

The stated goals of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”) are to increase corporate responsibility, to provide for 
enhanced penalties for accounting and auditing improprieties at publicly traded companies and to protect investors by improving 
the  accuracy  and  reliability  of  corporate  disclosures  pursuant  to  the  securities  laws.  Sarbanes-Oxley  generally  applies  to  all 
companies, both U.S. and non-U.S., that file or are required to file periodic reports under the Securities Exchange Act of 1934 
(the “Exchange Act”). 

Sarbanes-Oxley includes very specific additional disclosure requirements and corporate governance rules, required the SEC and 
securities exchanges to adopt extensive additional disclosure, corporate governance and other related rules and mandates further 
studies of certain issues. Sarbanes-Oxley represents significant federal involvement in matters traditionally left to state regulatory 
systems, such as the regulation of the accounting profession, and to state corporate law, such as the relationship between a board 
of directors and management and between a board of directors and its committees and public company shareholders. Sarbanes-
Oxley addresses, among other matters: (i) independent audit committees for reporting companies whose securities are listed on 
national  exchanges  or  automated  quotation  systems  and  expanded  duties  and  responsibilities  for  audit  committees;  (ii) 
certification of financial statements by the chief executive officer and the chief financial officer; (iii) the forfeiture of bonuses or 
other incentive-based compensation and profits from the sale of an issuer’s securities by directors and senior officers in the twelve 
month period following initial publication of any financial statements that later require restatement; (iv) a prohibition on insider 
trading during pension plan blackout periods; (v) disclosure of off-balance sheet transactions; (vi) a prohibition on personal loans 
to directors and officers under most circumstances with exceptions for certain normal course transactions by regulated financial 
institutions; (vii) expedited electronic filing requirements related to trading by insiders in an issuer’s securities on Form 4; (viii) 
disclosure  of  a  code  of  ethics  and  filing  a  Form  8-K  for  a  change  or  waiver  of  such  code;  (ix)  accelerated  filing  of  periodic 
reports; (x) the formation of the Public Company Accounting Oversight Board (“PCAOB”) to  regulate public accounting firms 
and  the  audit  of  public  companies  that  are  subject  to  the  securities  laws;  (xi)  auditor  independence;  (xii)  internal  control 
evaluation and reporting; and (xiii) various increased criminal penalties for violations of securities laws.

Programs To Mitigate Identity Theft 

In  November  2007,  federal  banking  agencies  together  with  the  National  Credit  Union  Administration  and  Federal  Trade 
Commission adopted regulations under the Fair and Accurate Credit Transactions Act of 2003 to require financial institutions and 
other creditors to develop and implement a written identity theft prevention program to detect, prevent and mitigate identity theft 
in connection with certain new and existing accounts. Covered accounts generally include consumer accounts and other accounts 
that  present  a  reasonably  foreseeable  risk  of  identity  theft.  Each  institution’s  program  must  include  policies  and  procedures 
designed  to:  (i)  identify  indicators,  or  “red  flags,”  of  possible  risk  of  identity  theft;  (ii)  detect  the  occurrence  of  red  flags;  (iii) 
respond  appropriately  to  red  flags  that  are  detected;  and  (iv)  ensure  that  the  program  is  updated  periodically  as  appropriate  to 
address  changing  circumstances.  The  regulations  include  guidelines  that  each  institution  must  consider  and,  to  the  extent 
appropriate, include in its program. 

Pending Legislation  

Changes to state laws and regulations (including changes in interpretation or enforcement) can affect the operating environment 
of  BHCs  and  their  subsidiaries  in  substantial  and  unpredictable  ways.  From  time  to  time,  various  legislative  and  regulatory 
proposals are introduced. These proposals, if codified, may change banking statutes and regulations and the Company’s operating 
environment  in  substantial  and  unpredictable  ways.  If  codified,  these  proposals  could  increase  or  decrease  the  cost  of  doing 
business, limit or expand permissible activities or affect the competitive balance among banks, savings associations, credit unions 
and other financial institutions. The Company cannot accurately predict whether those changes in laws and regulations will occur, 
and, if those changes occur, the ultimate effect they would have upon our financial condition or results of operations. It is likely, 
however, that the current level of enforcement and compliance-related activities of federal and state authorities will continue and 
potentially increase. 

Competition  

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. 

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 FRB, and pricing practices of the Company’s competitors. Changes in monetary policy, including changes in 
interest rates, will influence the origination of loans, the purchase of investments, the generation of deposits and other borrowings, 
and the rates received on loans and investment securities and paid on deposits and other liabilities. 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. 

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. 

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, 2018. Pursuant to its stock option plans, at 
December  31,  2018,  the  Company  had  outstanding  options  for  946  thousand  shares  of  common  stock,  of  which  457  thousand 
were  currently exercisable. As of December 31, 2018, 713 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’s payment of dividends on common stock could be eliminated or reduced. 

Holders of the Company’s common stock are entitled to receive dividends only when, as and if declared by the Company’s Board 
of Directors. Although the Company has historically paid cash dividends on the Company’s common stock, the Company is not 
required to do so and the Company’s Board of Directors could reduce or eliminate the Company’s common stock dividend in the 
future.

The Company could repurchase shares of its common stock at price levels considered excessive.  

The  Company  repurchases  and  retires  its  common  stock  in  accordance  with  Board  of  Directors-approved  share  repurchase 
programs.  At  December  31,  2018,  approximately  1.8  million  shares  remained  available  to  repurchase  under  such  plans.  The 
Company has been active in repurchasing and retiring shares of its common stock when alternative uses of excess capital, such as 
acquisitions, have been limited. The Company could repurchase shares of its common stock at price levels considered excessive, 
thereby spending more cash on such repurchases as deemed reasonable and effectively retiring fewer shares than would be retired 
if repurchases were effected at lower prices. 

Risks Related to the Nature and Geographical Location of the Company’s Business  

The Company invests in loans that contain inherent credit risks that may cause the Company to incur losses. 

The  risk  that  borrowers  may  not  pay  interest  or  repay  their  loans  as  agreed  is  an  inherent  risk  of  the  banking  business.  The 
company mitigates 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, 2018, real estate served as the principal source of collateral with respect to approximately 55% of 
the Company’s loan portfolio. The Company’s financial condition and operating results will be subject to changes in economic 
conditions in California. The California economy was severely affected by the recessionary period of 2008 to 2009. Much of the 
California  real  estate  market  experienced  a  decline  in  values  of  varying  degrees.  This  decline  had  an  adverse  impact  on  the 
business of some of the Company’s borrowers and on the value of the collateral for many of the Company’s loans. Generally, the 
counties  surrounding  and  near  San  Francisco  Bay  have  recovered  more  soundly  from  the  recent  recession  than  counties  in  the 
California  “Central  Valley,”  from  Sacramento  in  the  north  to  Bakersfield  in  the  south.  Approximately  22%  of  the  Company’s 
loans are to borrowers in the California “Central Valley.” Economic conditions in California’s diverse geographic markets can be 
vastly  different  and  are  subject  to  various  uncertainties,  including  the  condition  of  the  construction  and  real  estate  sectors,  the 
effect of drought on the agricultural sector and its infrastructure, and  the California state 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 could have a material adverse effect on the Company’s financial 
condition and results of operations.  

A sustained or continuing weakness or weakening in business and economic conditions generally or specifically in the principal 
markets  in  which  the  Company  does  business  could  have  one  or  more  of  the  following  adverse  impacts  on  the  Company’s 
business:  

 
 

a decrease in the demand for loans and other products and services offered by the Company;  
an increase or decrease in the usage of unfunded credit commitments;

 
 
 
 

 
 
 

an increase or decrease in the amount of deposits; 
a decrease in non-depository funding available to the Company; 
an impairment of certain intangible assets, including goodwill;  
an increase in the number of clients and counterparties who become delinquent, file for protection under bankruptcy laws 
or  default  on  their  loans  or  other  obligations  to  the  Company,  which  could  result  in  a  higher  level  of  nonperforming 
assets, net charge-offs, provision for loan losses, reduced interest revenue and cash flows, and valuation adjustments on 
assets; 
an impairment in the value of investment securities; 
an impairment in the value of life insurance policies owned by the Company; 
an impairment in the value of real estate owned by the Company. 

The 2008 - 2009 financial crisis led to the failure or merger of a number of financial institutions. Financial institution failures can 
result in further losses as a consequence of defaults on securities issued by them and defaults under contracts entered into with 
such entities as counterparties. The failure of institutions with FDIC insured deposits can cause the DIF reserve ratio to decline, 
resulting  in  increased  deposit  insurance  assessments  on  surviving  FDIC  insured  institutions.  Weak  economic  conditions  can 
significantly weaken the strength and liquidity of financial institutions. 

The Company’s financial performance generally, and in particular the ability of borrowers to pay interest on and repay principal 
of outstanding loans and the value of collateral securing those loans, are highly dependent upon the business environment in the 
markets  where  the  Company  operates,  in  the  State  of  California  and  in  the  United  States  as  a  whole.  A  favorable  business 
environment  is  generally  characterized  by,  among  other  factors,  economic  growth,  healthy  labor  markets,  efficient  capital 
markets, low inflation, high business and investor confidence, and strong business earnings. Unfavorable or uncertain economic 
and  market  conditions  can  be  caused  by:  declines  in  economic  growth,  high  rates  of  unemployment,  deflation,  declines  in 
business activity or consumer, investor or business confidence; limitations on the availability of or increases in the cost of credit 
and capital; increases in inflation; natural disasters; or a combination of these or other factors. 

Such business conditions could adversely affect the credit quality of the  Company’s loans, the demand for loans, loan volumes 
and  related  revenue,  securities  valuations,  amounts  of  deposits,  availability  of  funding,  results  of  operations  and  financial 
condition. 

Regulatory Risks 

Restrictions on dividends and other distributions could limit amounts payable to the Company. 

As  a  holding  company,  a  substantial  portion  of  the  Company’s  cash  flow  typically  comes  from  dividends  paid  by  the  Bank. 
Various  statutory  provisions  restrict  the  amount  of  dividends  the  Company’s  subsidiaries  can  pay  to  the  Company  without 
regulatory approval. A reduction in  subsidiary dividends paid to the Company could limit the capacity of the  Company  to pay 
dividends. In addition, if any of the Company’s subsidiaries were to liquidate, that subsidiary’s creditors will be entitled to receive 
distributions  from  the  assets  of  that  subsidiary  to  satisfy  their  claims  against  it  before  the  Company,  as  a  holder  of  an  equity 
interest in the subsidiary, will be entitled to receive any of the assets of the subsidiary. 

Adverse  effects  of  changes  in  banking  or  other  laws  and  regulations  or  governmental  fiscal  or  monetary  policies  could 
adversely affect the Company. 

The  Company  is  subject  to  significant  federal  and  state  regulation  and  supervision,  which  is  primarily  for  the  benefit  and 
protection  of  the  Company’s  customers  and  not  for  the  benefit  of  investors.  In  the  past,  the  Company’s  business  has  been 
materially affected by these regulations. 

Laws,  regulations  or  policies,  including  accounting  standards  and  interpretations  currently  affecting  the  Company  and  the 
Company’s subsidiaries, may change at any time. Regulatory authorities may also change their interpretation of these statutes and 
regulations. Therefore, the Company’s business may be adversely affected by any future changes in laws, regulations, policies or 
interpretations or regulatory approaches to compliance and enforcement including future acts of terrorism, major U.S. corporate 
bankruptcies and reports of accounting irregularities at U.S. public companies. 

Additionally, the Company’s business is affected significantly by the fiscal and monetary policies of the federal government and 
its agencies. The Company is particularly affected by the policies of the FRB, which regulates the supply of money and credit in 
the United States of America. Among the instruments of monetary policy available to the FRB are (a) conducting open market 

- 12 - 
12

2018   WESTAMERICA BANCORPORATION FORM 10-K 
 
 
 
 
 
 
 
 
 
 
 
operations in U.S. government securities, (b) changing the discount rates of borrowings by depository institutions,  (c) changing 
interest  rates  paid  on  balances  financial  institutions  deposit  with  the  FRB,  and  (d)  imposing  or  changing  reserve  requirements 
against certain borrowings by banks and their affiliates. These methods are used in varying degrees and combinations to directly 
affect the availability of bank loans and deposits, as well as the interest rates charged on loans and paid on deposits. The policies 
of  the  FRB  may  have  a  material  effect  on  the  Company’s  business,  results  of  operations  and  financial  condition.  Under  long- 
standing policy of the FRB, a BHC is expected to act as a source of financial strength for its subsidiary banks. As a result of that 
policy, the Company may be required to commit financial and other resources to its subsidiary bank in circumstances where the 
Company might not otherwise do so. 

Following  the  recessions  of  2008  and  2009,  the  FRB  provided  vast  amounts  of  liquidity  into  the  banking  system.  The  FRB 
purchased large quantities of U.S. government securities, including agency-backed mortgage securities, increasing the demand for 
such securities thereby reducing interest rates. Interest rates remained historically low through 2016 as the monetary policy of the 
Federal  Open  Market  Committee  (the  “FOMC”)  was  highly  accommodative.  The  FRB  began  reducing  these  asset  purchase 
activities in the fourth quarter 2013 and the FOMC began removing monetary stimulus in December 2016 and has increased the 
federal funds rate by 2.00 percent to 2.50 percent through December 2018. The raised target range for the federal funds rate could 
reduce  liquidity  in  the  markets  and  cause  interest  rates  to  rise,  thereby  increasing  funding  costs  to  the  Bank,  reducing  the 
availability  of  funds  to  the  Bank  to  finance  its  existing  operations,  and  causing  fixed-rate  investment  securities  and  loans  to 
decline in value. 

Federal and state governments could pass legislation detrimental to the Company’s performance.  

As an example, the Company could experience higher credit losses because of federal or state legislation or regulatory action that 
reduces  the  amount  the  Bank's  borrowers  are  otherwise  contractually  required  to  pay  under  existing  loan  contracts.  Also,  the 
Company could experience higher credit losses because of federal or state legislation or regulatory action that limits or delays the 
Bank's ability to foreclose on property or other collateral or makes foreclosure less economically feasible. Federal, state and local 
governments could pass tax legislation causing the Company to pay higher levels of taxes. 

The FDIC insures deposits at insured financial institutions  up to certain limits. The FDIC charges insured financial institutions 
premiums to maintain the Deposit Insurance Fund. The FDIC may increase premium assessments to maintain adequate funding of 
the Deposit Insurance Fund. 

The behavior of depositors in regard to the level of FDIC insurance could cause our existing customers to reduce the amount of 
deposits held at the Bank, and could cause new customers to open deposit accounts at the Bank. The level and composition of the 
Bank's deposit portfolio directly impacts the Bank's funding cost and net interest margin. 

Systems, Accounting and Internal Control Risks  

The accuracy of the Company’s judgments and estimates about financial and accounting matters will impact operating results 
and financial condition. 

The discussion under “Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical 
Accounting  Policies”  in  this  Report  and  the  information  referred  to  in  that  discussion  is  incorporated  by  reference  in  this 
paragraph. The Company makes certain estimates and judgments in preparing its financial statements. The quality and accuracy 
of those estimates and judgments will have an impact on the Company’s operating results and financial condition. 

A new accounting standard will significantly change the manner in which the Company recognizes credit losses and may have 
a material impact on the Company’s results of operations, financial condition or liquidity. 

In  June  2016,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  a  new  accounting  update,  FASB  ASU  2016-13, 
Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU changes 
the  accounting  for estimates  for credit losses related to financial assets  measured at amortized cost and certain other contracts. 
The  ASU  replaces  the  currently  incurred  loss  model  with  model  based  on  current  expected  credit  loss  (“CECL”),  which  will 
accelerate  recognition  of  credit  losses.  Additionally  credit  losses  relating  to  debt  securities  available-for-sale  will  be  recorded 
through an allowance for credit losses under the new standard. The Company will be required to adopt the ASU provisions on 
January 1, 2010. The ASU will significantly change the manner in which the Company determines the adequacy of its allowance 
for loan losses. The Company is evaluating the impact the CECL model will have, but the Company may recognize a one-time 
cumulative-effect adjustment to its allowance for loan losses as of the beginning of the first reporting period in which the new 
standard is effective. Any required adjustment to the allowance for loan losses resulting from this change in methodology will be 

- 13 - 
13

2018      WESTAMERICA BANCORPORATION FORM 10-K 
 
 
 
 
 
 
 
 
 
 
 
accomplished through an offsetting after-tax-adjustment  to  shareholders’  equity.  Moreover,  the  CECL  model may create more 
volatility in the level of the allowance for loan losses after adoption. If the Company is required to materially increase the level of 
its allowance for loan losses for any reason, such increase could adversely affect its business, financial condition and results of 
operations. 

The Company’s information systems may experience an interruption or breach in security.

The Company relies heavily on communications and information systems, including those of third party vendors and other service 
providers, to conduct its business. Any failure, interruption or breach in security of these systems could result in failures or 
disruptions in the Company’s data processing, accounting, customer relationship management and other systems. Communication 
and information systems failures can result from a variety of risks including, but not limited to, events that are wholly or partially 
out  of  the  Company’s  control,  such  as  telecommunication line integrity, weather, terrorist acts, natural disasters, accidental 
disasters, unauthorized breaches of security systems, energy delivery systems, cyber attacks, and other events. Although the 
Company devotes significant resources to maintain and regularly upgrade its systems and processes that are designed to protect 
the security of the Company’s computer systems, software, networks and other technology assets and the confidentiality, integrity 
and availability of information belonging to the Company and its customers, there is no assurance that any such failures, 
interruptions or security breaches will not occur or, if they do occur, that they will be adequately corrected by the Company or its 
vendors. The occurrence of any such failures, interruptions or security breaches could damage the Company’s reputation, result in 
a  loss of customer business, subject the Company to additional regulatory scrutiny, or expose the Company to litigation and 
possible financial liability, any of which could have a material adverse effect on the Company’s financial condition and results of 
operations. 

The Company’s controls and procedures may fail or be circumvented.

Management  regularly  reviews  and  updates  the  Company’s  internal  control  over  financial  reporting,  disclosure  controls  and 
procedures, and corporate governance policies and procedures. The Company maintains controls and procedures to mitigate 
against risks such as processing system failures and errors, and customer or employee fraud, and maintains insurance coverage for 
certain of these risks. Any system of controls and procedures, however well designed and operated, is based in part on certain 
assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Events could
occur which are not prevented or detected by the Company’s internal controls or are not insured against or are in excess of the 
Company’s  insurance  limits or  insurance  underwriters’  financial  capacity.  Any  failure  or  circumvention  of  the  Company’s 
controls and procedures or failure to comply with regulations related to controls and procedures could have a  material adverse 
effect on the Company’s business, results of operations and financial condition.

California. WAB 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 58 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. 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. In the

As of January 31, 2019, there were approximately 5,500 shareholders of record of the Company’s common stock. 

The Company has paid cash dividends on its common stock in every quarter since its formation in 1972. See Item 8, Financial 
Statements and Supplementary Data, Note 20 to the consolidated financial statements for recent quarterly dividend information. It 
is currently the intention of the Board of Directors of the Company to continue payment of cash dividends on a quarterly basis. 
There is no assurance, however, that any dividends will be paid since they are dependent upon earnings, cash balances, financial 
condition and capital requirements of the Company and its subsidiaries as well as policies of the FRB pursuant to the BHCA. See 
Item 1, “Business - Supervision and Regulation.” 

The notes to the consolidated financial statements included in this Report contain additional information regarding the Company’s 
capital levels,  capital  structure,  regulations affecting  subsidiary bank dividends paid to  the  Company, the  Company’s earnings, 
financial condition and cash flows, and cash dividends declared and paid on common stock.

(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).

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

The  following  discussion  addresses  information  pertaining  to  the  financial  condition  and  results  of  operations  of  Westamerica 
Bancorporation and subsidiaries (the “Company”) that may not be otherwise apparent from a review of the consolidated financial 
statements and related footnotes. It should be read in conjunction with those statements and notes found on pages 48 through 90, 
as well as with the other information presented throughout this Report. 

Critical Accounting Policies 

The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the 
United States of America and follow general practices within the banking industry. Application of these principles requires  the 
Company to make certain estimates, assumptions, and judgments that affect the amounts reported in the financial statements and 
accompanying  notes.  These  estimates,  assumptions,  and  judgments  are  based  on  information  available  as  of  the  date  of  the 
financial  statements;  accordingly,  as  this  information  changes,  the  financial  statements  could  reflect  different  estimates, 
assumptions, and judgments. Certain accounting policies inherently have a greater reliance on the use of estimates, assumptions 
and  judgments  and  as  such  have  a  greater  possibility  of  producing  results  that  could  be  materially  different  than  originally 
reported. Estimates, assumptions and judgments are necessary when assets and liabilities are required to be recorded at fair value, 
when a decline in the value of an asset not carried on the financial statements at fair value warrants an impairment writedown or 
valuation reserve to be established, or when an asset or liability needs to be recorded contingent upon a  future event.  Carrying 
assets and liabilities at fair value inherently results in more financial statement volatility. The fair values and the information used 
to record valuation adjustments for certain assets and liabilities are based either on quoted market prices or are provided by other 
third-party sources, when available. 

The  most  significant  accounting  policies  followed  by  the  Company  are  presented  in  Note  1  to  the  consolidated  financial 
statements.  These  policies,  along  with  the  disclosures  presented  in  the  other  financial  statement  notes  and  in  this  discussion, 
provide  information  on  how  significant  assets  and  liabilities  are  valued  in  the  financial  statements  and  how  those  values  are 
determined.  Based  on  the  valuation  techniques  used  and  the  sensitivity  of  financial  statement  amounts  to  the  methods, 
assumptions, and estimates underlying those amounts, Management has identified the allowance for loan losses accounting to be 
the accounting area requiring the most subjective or complex judgments, and as such could be  most subject to revision as new 
information becomes available. A discussion of the factors affecting accounting for the allowance for loan losses and purchased 
loans is included in the “Loan Portfolio Credit Risk” discussion below.  

Financial Overview  

Westamerica  Bancorporation  and  subsidiaries’  (collectively,  the  “Company”)  reported  net  income  of  $71.6  million  or  $2.67 
diluted earnings per common share (“EPS”) in 2018. The 2018 results include a $585 thousand tax-exempt life insurance policy 
gain  and  a  $3.5  million  loss  contingency  settlement,  which  on  an  aggregate  basis  reduced  EPS  $0.07.  In  2018,  the  Company 
achieved a mediated settlement to dismiss a lawsuit, subject to court approval, and accrued a liability for such amount. The  2018 
results  compare  to  net  income  of  $50.0  million  or  $1.89  EPS  for  the  year  ended  December  31,  2017  and  net  income  of  $58.9 
million or $2.29 EPS for the year ended December 31, 2016. The 2017 results include $12.3 million in adjustments to net deferred 
tax asset values triggered by enactment of the Tax Cuts and Jobs Act of 2017 (the “Act”) which reduced EPS $0.48, recognition 
of a $5.5 million loss contingency, which reduced EPS $0.12, and securities gains of $8.0 million, which increased EPS $0.18. 

The Company’s principal source of revenue is net interest and loan fee income, which represents interest and fees earned on loans 
and  investment  securities  (“earning  assets”)  reduced  by  interest  paid  on  deposits  and  other  borrowings  (“interest-bearing 
liabilities”).  Market  interest  rates  declined  considerably  following  the  recession  of  2008  and  2009.  Interest  rates  remained 
historically  low  through  2016  as  the  monetary  policy  of  the  Federal  Open  Market  Committee  (the  “FOMC”)  was  highly 
accommodative. During this period, Management avoided originating long-dated, low-yielding loans given the potential impact of 
such assets on forward earning potential; as a result, loans declined and investment securities increased. The changed composition 
of the earning assets and low market interest rates pressured the net interest margin to lower levels. The FOMC began removing 
monetary stimulus in December 2016 and has increased the federal funds rate by 2.00 percent to 2.50 percent through December 
2018,  although  longer-term  rates  have  not  increased  by  a  similar  magnitude.  This  recent  increase  in  market  interest  rates  has 
begun benefiting the Company’s earning asset yields. However, the rising market rates have not resulted in higher rates paid on 
deposits. The funding source of the Company’s earning assets is primarily customer deposits. The Company’s long-term strategy 
includes  maximizing  checking  and  savings  deposits  as  these  types  of  deposits  are  lower-cost  and  less  sensitive  to  changes  in 

- 20 -

2018   WESTAMERICA BANCORPORATION FORM 10-K 
 
 
 
 
 
 
interest rates compared to time deposits. The 2018 average volume of checking and savings deposits was 95.6 percent of average 
total deposits.  

Credit quality remained solid with nonperforming assets totaling $5.8 million at December 31, 2018 and net chargeoffs of $1.7 
million in 2018. The Company did not recognize a provision for loan losses in 2018. 

The Company presents its net interest margin and net interest income on an FTE basis using the current statutory federal tax rate. 
Management believes the  FTE basis is  valuable to the reader because the  Company’s loan and investment securities portfolios 
contain a relatively large portion of municipal loans and securities that are federally tax exempt. The Company’s tax exempt loans 
and securities composition may not be similar to that of other banks, therefore in order to reflect the impact of the federally tax 
exempt loans and securities on the net interest margin and net interest income for comparability with other banks, the Company 
presents  its  net  interest  margin  and  net  interest  income  on  an  FTE  basis.  Yields  on  tax-exempt  securities  and  loans  have  been 
adjusted upward to reflect the effect of income exempt from federal income taxation at the federal statutory tax rate of 35% for 
2017 and 2016. Due to the Act, the federal tax rate became 21% for 2018; as such, the upward adjustment to reflect the effect of 
income exempt from federal taxation is lower in 2018. 

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  FASB  ASU 2016-09, Improvements to Employee Share-Based Payment Accounting effective  January 1, 
2017. The  2018 and  2017 results reflect  the Company’s prospective adoption of ASU 2016-09;  the  2018 and  2017 income tax 
provision was $737 thousand and $698 thousand, respectively, lower than would have been under accounting standards prior to 
the adoption of ASU 2016-09.

Comparing 2018 with 2017, net income increased $21.5 million. Net interest and loan fee income increased in 2018 compared 
with  2017  mostly  attributable  to  higher  average  balances  of  investments  and  higher  yields  on  earning  assets  as  market  interest 
rates rose. The increase was offset by lower average balances of loans. Net interest and loan fee income (FTE) in 2018 included a 
lower FTE adjustment than in 2017 due to the reduced federal corporate tax as a result of enactment of the Act. The provision for 
loan  losses  remained  zero,  reflecting  Management's  evaluation  of  losses  inherent  in  the  loan  portfolio.  In  2018,  noninterest 
income decreased $8.5 million compared with 2017 because 2017 results included $8.0 million in gains of sale of securities. The 
non-FTE book tax provision for 2018, which reflected the tax-exempt nature of a $585 thousand life insurance policy gain, was 
$19.4 million compared with $37.1 million for 2017, representing effective tax rates of 21.4% and 42.6%, respectively. The non-
FTE book tax provision for 2017 includes $12.3 million in adjustments to net deferred tax asset values triggered by enactment of 
the  Act.  The  federal  statutory  tax  rate  was  reduced  from  35%  in  2017  to  21%  in  2018 due  to  the  Act.  The  non-FTE  book  tax 
provisions for 2018 and 2017 include tax benefits of $737 thousand and $698 thousand, respectively, for tax deductions from the 
exercise of employee stock options which exceed related compensation expenses recognized in the financial statements.

Comparing  2017  with  2016, net  income  decreased  $8.8  million.  Net  interest  and  loan  fee  income  increased  in  2017 compared 
with 2016 mostly attributable to higher average balances of investments and higher net yield on taxable investments and interest-
bearing cash, offset by lower average balances of loans and lower yields on those loans. The Company recorded a $1.9 million 
reversal  of  provision  for  loan  losses  in  2017  and  a  $3.2  million  reversal  of  provision  for  loan  losses  in  2016,  reflecting 
Management's  evaluation  of  losses  inherent  in  the  loan  portfolio.  Noninterest  income  increased  in  2017  compared  with  2016 
because 2017 included $8.0 million in gains on sale of securities and higher income from merchant processing services, partially 
offset by lower service charges on deposit accounts. Noninterest expense increased due to a $5.5 million loss contingency and an 
impairment charge of tax credit investments, partially offset by reductions in professional fees. The non-FTE tax book provision 
for  2017  was  higher  than  in  2016  primarily  due  to  a  $12.3  million  charge  to  re-measure  the  Company’s  net  deferred  tax  asset 
triggered  by  enactment  of  the  Act.  The  2017  income  tax  provision  was  $698  thousand  lower  than  it  would  have  been  under 
accounting standards prior to the adoption of ASU 2016-09. 

Net Interest and Loan Fee Income (FTE) 

The Company's primary source of revenue is net interest income, or the difference between interest income earned on loans and 
investment securities and interest expense paid on interest-bearing deposits and other borrowings.

Comparing  2018  with  2017,  net  interest  and  loan  fee  income  increased  $13.4  million  due  to  higher  average  balances  of 
investments (up $270 million) and higher yield on interest earning assets (up 0.03%), offset by lower average balances of loans 
(down $106 million). The FTE adjustment was lower in 2018 compared with 2017 mainly due to the reduced federal corporate 
tax rate as a result of enactment of the Act. 

Comparing  2017  with  2016,  net  interest  and  loan  fee  income  increased  $2.6  million  mostly  due  to  higher  average  balances  of 
investments (up $255 million) and higher yield on taxable investments (up 0.13%) and interest-bearing cash (up 0.59%), offset by 
lower average balances of loans (down $109 million) and lower net yield on those loans (down 0.16%). 

The yield on earning assets (FTE) was 3.02% in 2018 and 2.99% in 2017, 3.08% in 2016. The 2018 yield on earning assets (FTE) 
reflected higher market interest rates which offset the impact of the reduced FTE adjustment.  

The Company’s funding cost was 0.04% in 2018 compared with 0.04% in 2017 and 0.05% in 2016. Average balances of time 
deposits declined $58  million from 2016 to 2018 while lower-cost checking and savings deposits grew  8% in the same period. 
Average balances of checking and saving deposits accounted for 95.6% of average total deposits in 2018 compared with 94.8% in 
2017 and 94.1% in 2016.

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 35 percent for 2016 and 2017. Due to the Tax 
Cuts  and  Jobs  Act  of  2017,  the  federal  tax  rate  is  21  percent  for  2018;  as  such,  the  upward  adjustment  to  reflect  the  effect  of 
income exempt from federal taxation is lower in 2018.

Provision for Loan Losses 

The  Company  manages  credit  costs  by  consistently  enforcing  conservative  underwriting  and  administration  procedures  and 
aggressively  pursuing  collection  efforts  with  debtors  experiencing  financial  difficulties.  The  provision  for  loan  losses  reflects 
Management's assessment of credit risk in the loan portfolio during each of the periods presented. 

The Company provided no provision for loan losses in 2018. The Company recorded a reversal of the provision for loan losses of 
$1.9  million  in  2017  and  $3.2  million  in  2016.  Classified  loans  declined  $9.3  million  (which  included  nonperforming  loans  of 
$4.9 million) in 2018. The provision for loan losses was zero in 2018, reflecting Management's evaluation of losses inherent in the 
loan  portfolio.  At  December  31,  2018,  the  Company  had  $5.7  million  in  residential  real  estate  secured  loans  which  are 
indemnified from loss by the FDIC  up to eighty percent of principal; the indemnification expired February 6, 2019. For further 
information regarding credit risk, net credit losses and the  allowance  for loan losses,  see the  “Loan Portfolio  Credit  Risk”  and 
“Allowance for Loan Losses” sections of this Report.

In 2018, noninterest income decreased $8.5 million compared with 2017 primarily because 2017 results included $8.0 million in 
gains  on  sale  of  securities.  Service  charges  on  deposit  accounts  decreased  $1.1  million  due  to  declines  in  fees  for  overdrafts, 
checking  accounts  and  analyzed  accounts.    The  decreases  in  other  noninterest  income  were  partially  offset  by  an  increase  in 
merchant  processing  services  fees  of  $1.2  million  due  to  successful  sales  efforts  and  higher  transaction  volumes  and  a  $585 
thousand life insurance gain in 2018. 

In 2017, noninterest income increased $10.1 million compared with 2016 mainly due to $8.0 million in gains on sale of securities.   
Merchant  processing  services  fees  increased  $2.0  million  due  to  successful  sales  efforts  and  higher  transaction  volumes.  ATM 
processing  fees  and  debit  card  fees  increased  $199  thousand  and  $131  thousand,  respectively,  primarily  due  to  increased 
transaction  volumes.  Trust  fees  increased  $189  thousand  due  to  successful  sales  efforts.  Offsetting  the  increase  were  service 
charges on deposits which decreased $1.2 million due to declines in fees charged on overdrawn and insufficient funds accounts 
(down $1.0 million) and lower fees on analyzed accounts (down $220 thousand).

In  2018,  noninterest  expense  decreased  $852  thousand  compared  with  2017.  The  2018  noninterest  expense  included  a  $3.5 
million mediated settlement to dismiss a lawsuit, subject to court approval. The 2017 noninterest expense included a $5.5 million 
loss contingency and a $625 thousand impairment of low income housing limited partnership investments due to enactment of the 
Act. The 2017 loss contingency represents the Company’s estimated refunds to customers of revenue recognized in prior years. 
Salaries  and  related  benefits  increased  $1.5  million  primarily  due  to  the  annual  merit  increase  cycle  and  higher  incentives  and 
employee  benefit  costs.  Professional  fees  increased  $681  thousand  due  to  higher  legal  and  consulting  fees.  Amortization  of 
intangibles decreased $1.2 million as assets are amortized on a declining balance method.

In 2017, noninterest expense increased $4.1 million compared with 2016. The 2017 noninterest expense included a $5.5 million 
loss contingency and a $625 thousand impairment of low income housing limited partnership investments due to enactment of the 
Act.  The  loss  contingency  represents  the  Company’s  estimated  refunds  to  customers  of  revenue  recognized  in  prior  years. 
Expenses  for  occupancy  and  equipment  increased  $413  thousand  due  to  technology  upgrades.  Outsourced  data  processing 
services  expense  increased  $530  thousand  primarily  due  to  additional  processing  services.  Professional  fees  decreased  $1.8 
million  due  to  lower  legal  fees  associated  with  nonperforming  assets.  Amortization  of  intangibles  decreased  $427  thousand  as 
assets are amortized on a declining balance method. Other noninterest expense decreased $505 thousand primarily due to lower 
insurance premiums. 

Provision for Income Tax 

The Company’s income tax provision was $19.4 million in 2018 compared with $37.1 million in 2017 and $21.1 million in 2016, 
representing effective tax rates of 21.4%, 42.6% and 26.4%, respectively. The 2017 income tax provision included a $12.3 million 
charge to re-measure the Company’s  net deferred tax asset triggered by enactment of the Tax Cuts and Jobs Act  of  2017. The 
book tax provisions for 2018 and 2017 include tax benefits of $737 thousand and $698 thousand, respectively, for tax deductions 
from the exercise of employee stock options which exceed related compensation expenses recognized in the financial statements. 
The lower effective tax rate for 2018 reflects a reduction in the federal corporate tax rate as a result of enactment of the  Act and 
the tax-exempt nature of a $585 thousand life insurance policy gain. 

Investment Securities Portfolio 

The Company maintains an investment securities portfolio consisting of securities issued by the U.S. Treasury, U.S. Government 
sponsored entities, agency and non-agency  mortgage backed securities,  state and political subdivisions, corporations, and other 
securities. 

Management  has  increased  the  investment  securities  portfolio  in  response  to  deposit  growth  and  loan  volume  declines.  The 
average carrying value of the Company’s investment securities portfolio was $3.6 billion for the year ended December 31, 2018 
compared with $3.4 billion for the year ended December 31, 2017. 

Management  continually  evaluates  the  Company’s  investment  securities  portfolio  in  response  to  established  asset/liability 
management objectives, changing market conditions that could affect profitability, liquidity, and the level of interest rate risk to 
which the Company is exposed.  These evaluations may cause Management to change the level of funds the Company deploys 
into  investment  securities  and  change  the  composition  of  the  Company’s  investment  securities  portfolio.  In  the  year  ended 
December 31, 2018, Management increased the holdings of corporate securities in order to improve yields without extending the 
duration of the bond portfolio. 

At December 31, 2018, substantially all of the Company’s investment securities continue to be investment grade rated by one or 
more major rating agencies. In addition to monitoring credit rating agency evaluations, Management performs its own evaluations 
regarding  the  credit  worthiness  of  the  issuer  or  the  securitized  assets  underlying  asset-backed  securities.  The  Company’s 
procedures  for  evaluating  investments  in  securities  are  in  accordance  with  guidance  issued  by  the  Board  of  Governors  of  the 
Federal  Reserve  System,  “Investing  in  Securities  without  Reliance  on  Nationally  Recognized  Statistical  Rating  Agencies”  (SR 
12-15) and other regulatory guidance. There have been no significant differences in the  Company’s internal analyses compared 
with the ratings assigned by the third party credit rating agencies. 

During  the  third  quarter  2018,  the  Atlantic  hurricane  season  caused  severe  damage  within  many  U.S.  states.    Management 
evaluated  investment  security  exposures  within  the  counties  receiving  disaster  designations.    The  Company’s  exposures  are 
limited  to  municipal  bond  and  utility  provider  corporate  debt  from  issuers  within  South  Carolina  counties,  the  state  of  North 
Carolina and the Florida panhandle, and has determined that the storms had no material impact on the valuation of its investment 
securities. 

Effective  January  1,  2018,  upon  adoption  of  ASU  2016-01,  equity  securities  included  in  the  Company’s  available  for  sale 
portfolio of $1,800 thousand were reclassified to equity securities. The reclassification of equity securities resulted in recording a 
cumulative effect adjustment to decrease retained earnings by $142 thousand, net of tax. 

At December 31, 2018, the market value of equity securities was $1,747 thousand. During the year ended December 31, 2018, the 
Company recognized gross unrealized holding losses of $52 thousand in earnings.

Loan Portfolio 

The  Company  originates  loans  with  the  intent  to  hold  such  assets  until  principal  is  repaid.  Management  follows  written  loan 
underwriting  policies  and  procedures  which  are  approved  by  the  Bank’s  Board  of  Directors.  Loans  are  underwritten  following 
approved underwriting standards and lending authorities within a formalized organizational structure. The Board of Directors also 
approves independent real estate appraisers to be used in obtaining estimated values for real property serving as loan collateral. 
Prevailing economic trends and conditions are also taken into consideration in loan underwriting practices. 

All  loan applications  must be for clearly defined legitimate purposes  with a determinable  primary source of repayment,  and as 
appropriate,  secondary  sources  of  repayment.  All  loans  are  supported  by  appropriate  documentation  such  as  current  financial 
statements,  tax  returns,  credit  reports,  collateral  information,  guarantor  asset  verification,  title  reports,  appraisals,  and  other 
relevant documentation.  

Commercial  loans  represent  term  loans  used  to  acquire  durable  business  assets  or  revolving  lines  of  credit  used  to  finance 
working  capital.  Underwriting  practices  evaluate  each  borrower’s  cash  flow  as  the  principal  source  of  loan  repayment. 
Commercial loans are generally secured by the borrower’s business assets as a secondary source of repayment. Commercial loans 
are  evaluated  for  credit-worthiness  based  on  prior  loan  performance  and  borrower  financial  information  including  cash  flow, 
borrower net worth and aggregate debt. 

Commercial  real  estate  loans  represent  term  loans  used  to  acquire  or  refinance  real  estate  to  be  operated  by  the  borrower  in  a 
commercial capacity. Underwriting practices evaluate each borrower’s global cash flow as the principal source of loan repayment, 
independent appraisal of value of the property, and other relevant factors. Commercial real estate loans are generally secured by a 
first lien on the property as a secondary source of repayment.  

Real  estate  construction  loans  represent  the  financing  of  real  estate  development.  Loan  principal  disbursements  are  controlled 
through the use of project budgets, and disbursements are approved based on construction progress, which is validated by project 
site inspections. A first lien on the real estate serves as collateral to secure the loan.  

Residential  real  estate  loans  generally  represent  first  lien  mortgages  used  by  the  borrower  to  purchase  or  refinance  a  principal 
residence. For interest-rate risk purposes, the Company offers only fully-amortizing, adjustable-rate  mortgages. In underwriting 
first lien mortgages, the Company evaluates each borrower’s ability to repay the loan, an independent appraisal of the value of the 
property,  and  other  relevant  factors.  The  Company  does  not  offer  riskier  mortgage  products,  such  as  non-amortizing  “interest-
only” mortgages and “negative amortization” mortgages. 

For loans secured by real estate, the Bank requires title insurance to insure the status of its lien and each borrower is obligated to 
insure  the  real  estate  collateral,  naming  the  Company  as  loss  payee,  in  an  amount  sufficient  to  repay  the  principal  amount 
outstanding in the event of a property casualty loss. 

Consumer  installment  and  other  loans  are  predominantly  comprised  of  indirect  automobile  loans  with  underwriting  based  on 
credit history and scores, personal income, debt service capacity, and collateral values.

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  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 the financial statements requires Management to estimate the amount of losses inherent in the loan portfolio 
and establish an allowance for credit losses. The allowance for credit losses is maintained by assessing or reversing a provision 
for loan losses through the Company’s earnings. In estimating credit losses, Management must exercise judgment in evaluating 
information  deemed  relevant,  such  as  financial  information  regarding  individual  borrowers,  overall  credit  loss  experience,  the 
amount  of  past  due,  nonperforming  and  classified  loans,  recommendations  of  regulatory  authorities,  prevailing  economic 
conditions  and  other  information.  The  amount  of  ultimate  losses  on  the  loan  portfolio  can  vary  from  the  estimated  amounts. 
Management follows a systematic methodology to estimate loss potential in an effort to reduce the differences between estimated 
and actual losses. 

The Company closely monitors the markets in which it conducts its lending operations and follows a strategy to control exposure 
to  loans  with  high  credit  risk.  The  Bank’s  organization  structure  separates  the  functions  of  business  development  and  loan 
underwriting; Management believes this segregation of duties avoids inherent conflicts of combining business development and 
loan approval functions. In measuring and managing credit risk, the Company adheres to the following practices. 

  The Bank maintains a Loan Review Department which reports directly to the audit committee of the Board of Directors. 
The Loan Review Department performs independent evaluations of loans to challenge the credit risk grades assigned by 
Management  using  grading  standards  employed  by  bank  regulatory  agencies.  Those  loans  judged  to  carry  higher  risk 
attributes  are  referred  to  as  “classified  loans.”  Classified  loans  receive  elevated  Management  attention  to  maximize 
collection.  

  The Bank maintains two loan administration offices whose sole responsibility is to manage and collect classified loans. 

Classified loans with higher levels of credit risk are further designated as “nonaccrual loans.” Management places classified loans 
on  nonaccrual  status  when  full  collection  of  contractual  interest  and  principal  payments  is  in  doubt.  Uncollected  interest 
previously accrued on loans placed on nonaccrual status is reversed as a charge against interest income. The Company does not 
accrue  interest  income  on  loans  following  placement  on  nonaccrual  status.  Interest  payments  received  on  nonaccrual  loans  are 
applied to reduce the carrying amount of the loan unless the carrying amount is well secured by loan collateral. “Nonperforming 
assets” include nonaccrual loans, loans 90 or more days past due and still accruing, and repossessed loan collateral (commonly 
referred to as “Other Real Estate Owned”).

Nonperforming assets have declined during 2018 due to payoffs, chargeoffs and sale of Other Real Estate Owned. At December 
31, 2018, one loan secured by commercial real estate with a balance of $3.9 million was on nonaccrual status. The remaining four 
nonaccrual loans held at December 31, 2018 had an average carrying value of $250 thousand and the largest carrying value was 
$516 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, 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 

The  Company’s  allowance  for  loan  losses  represents  Management’s  estimate  of  loan  losses  inherent  in  the  loan  portfolio.  In 
evaluating credit risk for loans, Management measures loss potential of the carrying value of loans. As described above, payments 
received on nonaccrual loans  may be applied against the principal balance of the loans until such time as  full collection of  the 
remaining recorded balance is expected.  

The following table summarizes the allowance for loan losses, chargeoffs and recoveries for the periods indicated:

The  Company's  allowance  for  loan  losses  is  maintained  at  a  level  considered  appropriate  to  provide  for  losses  that  can  be 
estimated based upon specific and general conditions. These include conditions unique to individual borrowers, as well as overall 
loan  loss  experience,  the  amount  of  past  due,  nonperforming  and  classified  loans,  recommendations  of  regulatory  authorities, 
prevailing economic conditions and other factors. A portion of the allowance is individually allocated to impaired loans whose 
full collectability of principal is uncertain. Such allocations are determined by Management based on loan-by-loan analyses. The 
Company evaluates for impairment all loans with outstanding principal balances in excess of $500 thousand which are classified 
or on nonaccrual status and all “troubled debt restructured” loans. The remainder of the loan portfolio is collectively evaluated for 
impairment  based  in  part  on  quantitative  analyses  of  historical  loan  loss  experience  of  loan  portfolio  segments  to  determine 
standard  loss  rates  for  each  segment.  The  loss  rate  for  each  loan  portfolio  segment  reflects  both  the  historical  loss  experience 
during  a  look-back  period  and  a  loss  emergence  period.  Liquidating  purchased  consumer  installment  loans  are  evaluated 
separately by applying historical loss rates to forecasted liquidating principal balances to measure losses inherent in this portfolio 
segment. The loss rates are applied to segmented loan balances to allocate the allowance to the segments of the loan portfolio.   

The remainder of the allowance is considered to be unallocated. The unallocated allowance is established to provide for probable 
losses  that  have  been  incurred  as  of  the  reporting  date  but  not  reflected  in  the  allocated  allowance.  The  unallocated  allowance 
addresses additional qualitative factors consistent with Management's analysis of the level of risks inherent in the loan portfolio, 
which are related to the risks of the Company's general lending activity. Included in the unallocated allowance is the risk of losses 
that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in loan 
chargeoff  history  (external  factors).  The  primary  external  factor  evaluated  by  the  Company  and  the  judgmental  amount  of 
unallocated reserve assigned by Management as of December 31, 2018 is economic and business conditions $0.4 million. Also 
included in the unallocated allowance is the risk of losses attributable to general attributes of the Company's loan portfolio and 
credit administration (internal factors). The internal factors evaluated by the Company and the judgmental amount of unallocated 
reserve assigned by Management are: loan review system $0.9 million, adequacy of lending Management and staff $0.8 million 
and concentrations of credit $1.0 million.

The portion of the allowance for loan losses ascribed to loan segments changed from December 31, 2017 to December 31, 2018 
based on Management’s evaluation of credit risk. The allowance for loan losses ascribed to commercial loans declined due to the 
improved  financial  performance  of  a  specific  borrower.  The  allowance  for  loan  losses  ascribed  to  construction  loans  increased 
based on an increased level of credit exposure relative to real property values. The allowance for loan losses ascribed to consumer 
installment loans declined due to Management’s measurement of a shortened loss emergence period.

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 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 
growth of loans, investment securities, and 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 and short-term interest rates. 

Management monitors the Company’s interest rate risk using a purchased simulation model, which is periodically validated 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 both a static and dynamic composition of financial 
instruments.  Within  the  static  composition  simulation,  cash  flows  are  assumed  redeployed  into  like  financial  instruments  at 
prevailing rates and yields. 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.  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  slightly  “asset sensitive” at  December 31, 2018, depending on the  interest rate 
assumptions applied to each simulation model. An “asset sensitive” position results in a slightly larger change in interest income 
than in interest expense resulting from application of assumed interest rate changes.  

At December 31, 2018, Management’s measurements of estimated changes in net interest income were: 

Static Simulation: 
Assumed Immediate Parallel Shift in Interest Rates 
First Year Change in Net Interest Income 

Dynamic Simulation: 
Assumed Change in Interest Rates Over 1 Year 
First Year Change in Net Interest Income

         +5.30% 

         +1.00% 
         +2.80% 

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.  

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 loan losses. The financial 
condition  and  liquidity  of  debtors  issuing  bonds  and  debtors  whose  mortgages  or  other  obligations  are  securitized  can  directly 
impact  the  credit  quality  of  the  Company’s  investment  securities  portfolio  requiring  the  Company  to  recognize  other  than 
temporary  impairment  charges.  Other  types  of  market  risk,  such  as  foreign  currency  exchange  risk,  are  not  significant  in  the 
normal course of the Company's business activities. 

Liquidity and Funding 

The  objective  of  liquidity  management  is  to  manage  cash  flow  and  liquidity  reserves  so  that  they  are  adequate  to  fund  the 
Company's  operations  and  meet  obligations  and  other  commitments  on  a  timely  basis  and  at  a  reasonable  cost.  The  Company 
achieves  this  objective  through  the  selection  of  asset  and  liability  maturity  mixes  that  it  believes  best  meet  its  needs.  The 
Company's liquidity position is enhanced by its ability to raise additional funds as needed in the wholesale markets. 

In  recent  years,  the  Company's  deposit  base  has  provided  the  majority  of  the  Company's  funding  requirements.  This  relatively 
stable and low-cost source of funds, along with shareholders' equity, provided 98 percent of funding for average total assets in the 
year ended December 31, 2018 and 2017. The stability of the Company’s funding from customer deposits is in part reliant on the 
confidence  clients  have  in  the  Company.  The  Company  places  a  very  high  priority  in  maintaining  this  confidence  through 
conservative credit and capital management practices and by maintaining an appropriate level of liquidity. 

Liquidity is further provided by assets such as balances held at the Federal Reserve Bank, investment securities, and amortizing 
loans.  The  Company's  investment  securities  portfolio  provides  a  substantial  secondary  source  of  liquidity.  The  Company  held 
$3.6 billion in total investment securities at  December 31, 2018. Under certain deposit, borrowing and other arrangements, the 
Company  must hold and pledge investment securities as collateral. At  December 31, 2018, such collateral requirements totaled 
approximately $728 million. 

Liquidity risk can result from the mismatching of asset and liability cash flows, or from disruptions in the financial markets. The 
Company performs liquidity stress tests on a periodic basis to evaluate the sustainability of its liquidity. Under the stress testing, 
the  Company assumes outflows of funds increase beyond expected levels. Measurement of such heightened outflows considers 
the composition of the Company’s deposit base, including any concentration of deposits, non-deposit funding such as short-term 
borrowings, and unfunded lending commitments. The Company evaluates its stock of highly liquid assets to  meet the assumed 
higher levels of outflows. Highly liquid assets include cash and amounts due from other banks from daily transaction settlements, 
reduced by branch cash needs and Federal Reserve Bank reserve requirements, and investment securities based on regulatory risk-
weighting  guidelines.  Based  on  the  results  of  the  most  recent  liquidity  stress  test,  Management  is  satisfied  with  the  liquidity 
condition of the Bank and the Company. However, no assurance can be given the Bank or Company will not experience a period 
of reduced liquidity. 

Management  continually  monitors  the  Company’s  cash  levels.  Loan  demand  from  credit  worthy  borrowers  will  be  dictated  by 
economic  and  competitive  conditions.  The  Company  aggressively  solicits  non-interest  bearing  demand  deposits  and  money 
market checking deposits, which are the least sensitive to changes in interest rates. The growth of these deposit balances is subject 
to heightened competition, the success of the Company's sales efforts, delivery of superior customer service, new regulations and 
market conditions. The Company does not aggressively solicit higher-costing time deposits; as a result, Management anticipates 
such deposits will decline. Changes in interest rates, most notably rising interest rates, could impact deposit volumes. Depending

on economic conditions, interest rate levels, liquidity management and a variety of other conditions, deposit growth may be used 
to  fund  loans  or  purchase  investment  securities.  However,  due  to  possible  volatility  in  economic  conditions,  competition  and 
political uncertainty, loan demand and levels of customer deposits are not certain. Shareholder dividends are expected to continue 
subject to the Board's discretion and continuing evaluation of capital levels, earnings, asset quality and other factors. 

Westamerica Bancorporation ("Parent Company") is a separate entity apart from 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 currently has no debt. 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 $43 million in 2018 and $41 million in 
2017, and retire common stock in the amount of $524 thousand in 2018 and $314 thousand in 2017. Payment of dividends to the 
Parent  Company  by  the  Bank  is  limited  under  California  and  Federal  laws.  The  Company  believes  these  regulatory  dividend 
restrictions will not have an impact on the Parent Company's ability to meet its ongoing cash obligations. 

Contractual Obligations 

Deposits  and  sort-term  borrowings  are  detailed  on  pages  43,  44  and  45.  The  following  table  sets  forth  the  known  contractual

Operating  lease  obligations  have  not  been  reduced  by  minimum  sublease  rentals  of  $1  million  due  in  the  future  under 
noncancelable subleases. Operating lease obligations may be retired prior to the contractual maturity as discussed in the notes to 
the  consolidated  financial  statements.  The  purchase  obligation  consists  of  the  Company’s  minimum  liabilities  under  contracts 
with third-party automation services providers. 

Capital Resources 

The Company has historically generated high levels of earnings, which provide a means of accumulating capital. The Company's 
net income as a percentage of average shareholders' equity (“return on equity” or “ROE”) has been 11.3% in 2018, 8.4% in 2017 
and 10.9% in 2016. The Company also raises capital as employees exercise stock options. Capital raised through the exercise of 
stock options was $13 million in 2018, $25 million in 2017 and $24 million in 2016. 

The Company paid common dividends totaling $43 million in 2018, $41 million in 2017 and $40 million in 2016, which represent 
dividends  per  common  share  of  $1.60,  $1.57  and  $1.56,  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 earnings to shareholders. The Company repurchased 
and  retired  9  thousand  shares  valued  at  $524  thousand  in  2018,  6  thousand  shares  valued  at  $314  thousand  in  2017  and  137 
thousand shares valued at $6 million in 2016. 

The Company's primary capital resource is shareholders' equity, which was $616 million at December 31, 2018 compared with 
$590 million at December 31, 2017. The Company's ratio of equity to total assets was 11.05% at December 31, 2018 and 10.71% 
at December 31, 2017. 

The Company performs capital stress tests on a periodic basis to evaluate the sustainability of its capital. Under the stress testing, 
the  Company  assumes  various  scenarios  such  as  deteriorating  economic  and  operating  conditions,  unanticipated  asset 
devaluations, and significant operational lapses. The Company measures the impact of these scenarios on its earnings and capital. 
Based  on  the  results  of  the  most  recent  stress  tests,  Management  is  satisfied  with  the  capital  condition  of  the  Bank  and  the

Company.  However,  no  assurance  can  be  given  the  Bank  or  Company  will  not  experience  a  period  of  reduced  earnings  or  a 
reduction in capital from unanticipated events and circumstances. 

Capital to Risk-Adjusted Assets 

On July 2, 2013, the Federal Reserve Board approved a final rule that implements changes to the regulatory capital framework for 
all banking organizations. The rule’s provisions which most affected the regulatory capital requirements of the Company and the 
Bank: 

Introduced a new “Common Equity Tier 1” capital measurement,  

 
  Established higher minimum levels of capital,  
 
Introduced a “capital conservation buffer,” 
 
Increased the risk-weighting of certain assets, and 
  Established limits on the amount of deferred tax assets with any excess treated as a deduction from Tier 1 capital. 

Under the final rule, a banking organization that is not subject to the “advanced approaches rule” may make a one-time election 
not to include most elements of Accumulated Other Comprehensive Income, including net-of-tax unrealized gains and losses on 
debt securities available for sale, in regulatory capital. Neither the Company nor the Bank is subject to the “advanced approaches 
rule”  and  both  made  the  election  not  to  include  most  elements  of  Accumulated  Other  Comprehensive  Income  in  regulatory 
capital. 

Banking organizations that are not subject to the “advanced approaches rule” began complying with the final rule on January 1, 
2015; on such date, the Company and the Bank became subject to the revised definitions of regulatory capital, the new minimum 
regulatory  capital  ratios,  and  various  regulatory  capital  adjustments  and  deductions  according  to  transition  provisions  and 
timelines. All banking organizations began calculating standardized total risk-weighted assets on January 1, 2015. The transition 
period  for  the  capital  conservation  buffer  for  all  banking  organizations  began  on  January  1,  2016  and  ended  January  1,  2019, 
when the 2.5% capital conservation buffer was fully implemented. Any bank subject to the rule which is unable to maintain its 
“capital  conservation  buffer”  above  the  minimum  regulatory  capital  ratios  will  be  restricted  in  the  payment  of  discretionary 
executive compensation and shareholder distributions, such as dividends and share repurchases. 

The final rule did not supersede provisions of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) requiring 
federal banking agencies to take prompt corrective action (PCA) to resolve problems of insured depository institutions. The final 
rule revised the PCA thresholds to incorporate the higher minimum levels of capital, including the “common equity tier 1” ratio.  

The capital ratios for the Company and the Bank under the new capital framework are presented in the tables below, on the dates 
indicated.

In June 2016, the Financial Accounting Standards Board issued an update to the accounting standards for credit losses known as 
the "Current Expected  Credit Losses" (CECL)  methodology,  which replaces the existing incurred loss  methodology  for certain 
financial assets.  The Company intends to timely adopt the CECL methodology January 1, 2020, which involves an implementing 
accounting entry to retained earnings. In December 2018, the federal bank regulatory agencies approved a final rule which will be 
effective April 1, 2019 modifying their regulatory capital rules and providing an option to phase in over a period of three years the 
day-one  regulatory  capital  effects  of  implementing  the  CECL  methodology.  The  Company  has  not  determined  whether  it  will 
elect the three year phase in period for the day-one regulatory capital effects. See Note 1 to the consolidated financial statements, 
“Summary  of  Significant  Accounting  Policies:  Recently  Issued  Accounting  Standards”  for  more  information  on  the  CECL 
methodology. 

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  Company  and  the  Bank  expect  to  maintain  regulatory  capital  levels  exceeding  the  highest  effective  regulatory 
standard and pay quarterly dividends to shareholders. No assurance can be given that changes in capital management plans will 
not occur. 

Deposit Categories 

The Company primarily attracts deposits from local businesses and professionals, as well as through retail savings and checking 
accounts, and, to a more limited extent, certificates of deposit.

The  Company’s  strategy  includes  building  the  value  of  its  deposit  base  by  building  balances  of  lower-costing  deposits  and 
avoiding reliance on higher-costing time deposits. From 2016 to 2018 higher costing time deposits declined from 6% to 4% of

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.

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, 2018. 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,  2018  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,  2018  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 91.

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. 

Summary of Significant Accounting Policies 

The  consolidated  financial  statements  are  prepared  in  conformity  with  accounting  principles  generally  accepted  in  the  United 
States  of  America.  The  following  is  a  summary  of  significant  policies  used  in  the  preparation  of  the  accompanying  financial 
statements. 

Accounting Estimates. Certain accounting policies underlying the preparation of  these financial statements require Management 
to  make  estimates,  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 loan 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 loan losses 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 and how Management expects them to change in the future, it is reasonably possible that in 2019 
actual conditions could be worse than anticipated in those estimates, which could materially affect our results of operations and 
financial condition. 

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 effective January 1, 2018 prior to such date unrealized gains and losses 
were included in other comprehensive income. 

Debt  Securities.  Debt  securities  consist  of  securities  of  the  U.S.  Treasury,  government  sponsored  entities,  states,  counties, 
municipalities,  corporations,  agency  and  non-agency  mortgage-backed  securities  and  asset-backed  securities.  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 

- 53 - 
53

2018      WESTAMERICA BANCORPORATION FORM 10-K 
 
 
 
 
 
 
 
 
 
 
 
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. 

The Company utilizes third-party sources to value its investment securities; securities individually valued using quoted prices in 
active  markets  are  classified  as  Level  1  assets  in  the  fair  value  hierarchy,  and  securities  valued  using  quoted  prices  in  active 
markets  for  similar  securities  (commonly  referred  to  as  “matrix”  pricing)  are  classified  as  Level  2  assets  in  the  fair  value 
hierarchy.  The  Company  validates  the  reliability  of  third-party  provided  values  by  comparing  individual  security  pricing  for 
securities  between  more  than  one  third-party  source.  When  third-party  information  is  not  available,  valuation  adjustments  are 
estimated in good faith by Management and classified as Level 3 in the fair value hierarchy. 

A decline in the market value of any available for sale or held to maturity security below amortized cost that is deemed other than 
temporary  results  in  a  charge  to  earnings  and  the  establishment  of  a  new  cost  basis  for  the  security.  Unrealized  investment 
securities  losses  are  evaluated  at  least  quarterly  to  determine  whether  such  declines  in  value  should  be  considered  “other  than 
temporary”  and  therefore  be  subject  to  immediate  loss  recognition  in  income.  Although  these  evaluations  involve  significant 
judgment, an unrealized loss in the fair value of a debt security is generally deemed to be temporary when the fair value of the 
security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration 
in  the  financial  condition  of  the  issuer,  and  the  Company  does  not  intend  to  sell  or  be  required  to  sell  the  securities  before 
recovery of its amortized cost. An unrealized loss in the value of an equity security is generally considered temporary when the 
fair value of the security declined primarily due to current market conditions and not deterioration in the financial condition of the 
issuer, the Company expects the fair value of the security to recover in the near term and the Company does not intend to sell or 
be required to sell the securities before recovery of its cost basis. Other factors that may be considered in determining whether a 
decline in the value of either a debt or an equity security is “other than temporary” include ratings by recognized rating agencies, 
actions of commercial banks or other lenders relative to the continued extension of credit facilities to the issuer of the security, the 
financial condition, capital strength and near-term prospects of the issuer, and recommendations of investment advisors or market 
analysts. 

The Company  follows the  guidance issued by  the Board of Governors of the  Federal Reserve  System,  “Investing  in  Securities 
without  Reliance  on  Nationally  Recognized  Statistical  Rating  Agencies”  (SR  12-15)  and  other  regulatory  guidance  when 
performing investment security pre-purchase analysis or evaluating investment securities for impairment. Credit ratings issued by 
recognized rating agencies are considered in the Company’s analysis only as a guide to the historical default rate associated with 
similarly-rated bonds. 

Purchase premiums are amortized and purchase discounts are accreted over the estimated life of the related investment security as 
an  adjustment  to  yield  using  the  effective  interest  method.  Unamortized  premiums,  unaccreted  discounts,  and  early  payment 
premiums are recognized  as a component of gain or loss on sale upon disposition of the related security. Interest and dividend 
income  are  recognized  when  earned.  Realized  gains  and  losses  from  the  sale  of  available  for  sale  securities  are  included  in 
earnings using the specific identification method. 

Nonmarketable  Equity  Securities.  Nonmarketable  equity  securities  include  securities  that  are  not  publicly  traded,  such  as  Visa 
Class B common stock, and securities acquired to meet regulatory requirements, such as Federal Reserve Bank stock, which are 
restricted.  These  restricted  securities  are  accounted  for  under  the  cost  method  and  are  included  in  other  assets.  The  Company 
reviews  those  assets  accounted  for  under  the  cost  method  at  least  quarterly  for  possible  declines  in  value  that  are  considered 
“other than temporary”. The Company’s review typically includes an analysis of the facts and circumstances of each investment, 
the expectations for the investment’s cash flows and capital needs, the viability of its business model and any exit strategy. The 
asset value is reduced when a decline in value is considered to be other than temporary. The Company recognizes  the estimated 
loss in noninterest income. 

Loans. Loans are stated at the principal amount outstanding, net of unearned discount and unamortized deferred fees and costs. 
Interest  is  accrued  daily  on  the  outstanding  principal  balances.  Loans  which  are  more  than  90  days  delinquent  with  respect  to 
interest  or  principal,  unless  they  are  well  secured  and  in  the  process  of  collection,  and  other  loans  on  which  full  recovery  of 
principal or interest is in doubt, are placed on nonaccrual status. Interest previously accrued on loans placed on nonaccrual status 
is  charged  against  interest  income.  In  addition,  some  loans  secured  by  real  estate  with  temporarily  impaired  values  and 
commercial  loans  to  borrowers  experiencing  financial  difficulties  are  placed  on  nonaccrual  status  (“performing  nonaccrual 
loans”)  even  though  the  borrowers  continue  to  repay  the  loans  as  scheduled.  When  the  ability  to  fully  collect  nonaccrual  loan 
principal  is  in  doubt,  payments  received  are  applied  against  the  principal  balance  of  the  loans  on  a  cost-recovery  method  until 
such time as full collection of the remaining recorded balance is expected. Any  additional interest payments received after that 
time  are  recorded  as  interest  income  on  a  cash  basis.  Performing  nonaccrual  loans  are  reinstated  to  accrual  status  when 

- 54 - 
54

2018   WESTAMERICA BANCORPORATION FORM 10-K 
 
 
 
 
 
 
 
improvements in credit quality eliminate the doubt as to the full  collectability of both  interest and principal.  Certain consumer 
loans or auto receivables are charged off against the allowance for credit losses when they become 120 days past due.  

The Company evaluates all classified loans and nonaccrual loans with outstanding principal balances in excess of $500 thousand, 
and all “troubled debt restructured” loans for impairment.  The Company recognizes a loan as impaired when, based on current 
information  and  events,  it  is  probable  that  it  will  be  unable  to  collect  both  the  contractual  interest  and  principal  payments  as 
scheduled  in  the  loan  agreement.  Income  recognition  on  impaired  loans  conforms  to  that  used  on  nonaccrual  loans.  In  certain 
circumstances,  the  Company  might  agree  to  restructured  loan  terms  with  borrowers  experiencing  financial  difficulties;  such 
restructured  loans  are  evaluated  under  ASC  310-40,  “Troubled  Debt  Restructurings  by  Creditors.”  In  general,  a  restructuring 
constitutes  a  troubled  debt  restructuring  when  the  Company,  for  reasons  related  to  a  borrower’s  financial  difficulties,  grants  a 
concession to the borrower it would not otherwise consider. Loans are evaluated on an individual basis. The Company follows its 
general nonaccrual policy for troubled debt restructurings. Performing troubled debt restructurings are reinstated to accrual status 
when improvements in credit quality eliminate the doubt as to full collectability of both principal and interest. 

Nonrefundable fees and certain costs associated with originating or acquiring loans are deferred and amortized as an adjustment 
to  interest  income  over  the  contractual  loan  lives.  Upon  prepayment,  unamortized  loan  fees,  net  of  costs,  are  immediately 
recognized in interest income. Other fees, including those collected upon principal prepayments, are included in interest  income 
when received.  Loans held  for sale  are identified  upon origination and are reported at the lower of cost or  market value on an 
aggregate loan basis. 

Purchased  Loans.    Purchased  loans  are  recorded  at  estimated  fair  value  on  the  date  of  purchase.  Impaired  purchased  loans  are 
accounted for under FASB ASC 310-30, Loans and Debt Securities  Acquired  with Deteriorated Credit Quality, when the loans 
have  evidence  of  credit  deterioration  since  origination  and  it  is  probable  at  the  date  of  acquisition  that  the  Company  will  not 
collect all contractually required principal and interest payments. Evidence of credit quality deterioration as of the purchase date 
may include attributes such as past due and nonaccural status. Generally, purchased loans that meet the Company’s definition for 
nonaccrual  status  fall  within  the  scope  of  FASB  ASC  310-30.  The  difference  between  contractually  required  payments  at 
acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. Subsequent 
decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result 
in  a  reversal  of  the  provision  for  loan  losses  to  the  extent  of  prior  charges,  or  a  reclassification  of  the  difference  from 
nonaccretable to accretable with a positive impact on interest income on a prospective basis. Any excess of expected cash flows 
over the estimated fair value is referred to as the accretable yield and is recognized into interest income over the remaining life of 
the loan  when there  is a reasonable expectation about  the  amount and timing of  such cash  flows.  For covered purchased loans 
with  an  accretable  difference,  the  corresponding  FDIC  receivable  is  amortized  over  the  shorter  of  the  contractual  term  of  the 
indemnification asset or the remaining life of the loan.  Further, the Company elected to analogize to ASC 310-30 and account for 
all other loans that had a discount due in part to credit not within the scope of ASC 310-30 using the same methodology. 

Covered  Loans.  Loans covered under loss-sharing or similar credit protection agreements  with the FDIC are reported in loans 
exclusive  of  the  expected  reimbursement  cash  flows  from  the  FDIC.  Covered  loans  are  initially  recorded  at  fair  value  at  the 
acquisition  date.  Subsequent  decreases  in  the  amount  expected  to  be  collected  results  in  a  provision  for  loan  losses  and  a 
corresponding increase in the estimated FDIC reimbursement, with the estimated net loss impacting earnings. Interest previously 
accrued on covered loans placed on nonaccrual status is charged against interest income, net of estimated FDIC reimbursements 
of such accrued interest. The FDIC reimburses the Company up to 80% of 90 days interest on covered loans. The indemnification 
expired February 6, 2019. 

Allowance  for  Credit  Losses.  The  Company  extends  loans  to  commercial  and  consumer  customers  primarily  in  Northern  and 
Central  California.  These  lending  activities  expose  the  Company  to  the  risk  borrowers  will  default,  causing  loan  losses.  The 
Company’s  lending  activities  are  exposed  to  various  qualitative  risks.  All  loan  segments  are  exposed  to  risks  inherent  in  the 
economy and  market conditions. Significant risk characteristics related to the commercial loan segment include the  borrowers’ 
business performance and financial condition, and the value of collateral for secured loans. Significant risk characteristics related 
to the commercial real estate segment include the borrowers’ business performance and the value of properties collateralizing the 
loans. Significant risk characteristics related to the construction loan segment include the borrowers’ performance in successfully 
developing  the  real  estate  into  the  intended  purpose  and  the  value  of  the  property  collateralizing  the  loans.  Significant  risk 
characteristics related to the residential real estate segment include the borrowers’ financial wherewithal to service the mortgages 
and  the  value  of  the  property  collateralizing  the  loans.  Significant  risk  characteristics  related  to  the  consumer  loan  segment 
include the financial condition of the borrowers and the value of collateral securing the loans. 

The preparation of these financial statements requires Management to estimate the amount of probable incurred losses inherent in 
the loan portfolio and establish an allowance for credit losses. In estimating credit losses, Management must exercise  significant 

- 55 - 
55

2018      WESTAMERICA BANCORPORATION FORM 10-K 
 
 
 
 
 
 
 
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, including 
impaired loans, are charged to the allowance for loan losses when all or a portion of the recorded amount of a loan is deemed to 
be  uncollectible.  Recoveries  of  loans  previously  charged  off  are  credited  to  the  allowance  when  realized.  The  Company’s 
allowance for credit losses is  maintained at a level considered adequate  to provide  for losses that can be  estimated based upon 
specific and general conditions. These include conditions unique to individual borrowers, as well as overall credit loss experience, 
the  amount  of  past  due,  nonperforming  and  classified  loans,  recommendations  of  regulatory  authorities,  prevailing  economic 
conditions, FDIC loss-sharing or similar credit protection agreements and other factors. A portion of the allowance is specifically 
allocated to impaired loans whose full collectability is uncertain. Such allocations are determined by Management based on loan-
by-loan analyses. The Company evaluates all classified loans and nonaccrual loans with outstanding principal balances in excess 
of $500 thousand, and all “troubled debt restructured” loans for impairment.  A second allocation is based in part on quantitative 
analyses of historical credit loss experience. The results of this analysis are applied to current loan balances to allocate the reserve 
to the respective segments of the loan portfolio exclusive of loans individually evaluated for impairment. In addition, consumer 
installment  loans  which  have  similar characteristics  and are  not  usually criticized  using  regulatory  guidelines are analyzed  and 
reserves established  based on the historical loss rates and delinquency trends, grouped by the number of days the payments on 
these loans are delinquent. The remainder of the reserve is considered to be unallocated. The unallocated allowance is established 
to  provide  for  probable  losses  that  have  been  incurred  as  of  the  reporting  date  but  not  reflected  in  the  allocated  allowance.  It 
addresses additional qualitative factors consistent with Management’s analysis of the level of risks inherent in the loan portfolio, 
which are related to the risks of the Company’s general lending activity. Included in the unallocated allowance is the risk of losses 
that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in past 
loan  charge-off  history  (external  factors).  The  external  factors  evaluated  by  the  Company  include:  economic  and  business 
conditions, external competitive issues, and other factors. Also included in the unallocated allowance is the risk of losses that are 
attributable to general attributes of the Company’s loan portfolio and credit administration (internal factors). The internal factors 
evaluated by the Company include: loan review system, adequacy of lending Management and staff, loan policies and procedures, 
problem  loan  trends,  concentrations  of  credit,  and  other  factors.  By  their  nature,  these  risks  are  not  readily  allocable  to  any 
specific segment of the loan portfolio in a statistically meaningful manner. 

Liability for Off-Balance Sheet Credit Exposures. A liability for off-balance sheet credit exposures is established through expense 
recognition.  Off-balance  sheet  credit  exposures  relate  to  letters  of  credit  and  unfunded  loan  commitments  for  commercial, 
construction and consumer loans. Historical credit loss factors for commercial, construction and consumer loans are applied to the 
amount of these off-balance sheet credit exposures to estimate inherent losses. 

Other  Real  Estate  Owned.  Other  real  estate  owned  is  comprised  of  property  acquired  through  foreclosure  proceedings, 
acceptances of deeds-in-lieu of foreclosure and, if applicable, vacated bank properties. Losses recognized at the time of acquiring 
property  in  full  or  partial  satisfaction  of  debt  are  charged  against  the  allowance  for  credit  losses.  Other  real  estate  owned  is 
recorded  at  the  fair  value  of  the  collateral,  generally  based  upon  an  independent  property  appraisal,  less  estimated  disposition 
costs. Losses incurred subsequent to acquisition due to any decline in annual independent property appraisals are recognized as 
noninterest  expense.  Routine  holding  costs,  such  as  property  taxes,  insurance  and  maintenance,  and  losses  from  sales  and 
dispositions, are recognized as noninterest expense. 

Premises  and  Equipment.  Premises  and  equipment  are  stated  at  cost,  less  accumulated  depreciation  and  amortization. 
Depreciation is computed substantially on the straight-line method over the estimated useful life of each type of asset. Estimated 
useful lives of premises and equipment range from 20 to 50 years and from 3 to 20 years, respectively. Leasehold improvements 
are amortized over the terms of the lease or their estimated useful life, whichever is shorter. 

Revenue Recognition.  The Company recognizes revenue as it is earned based on contractual terms, as transactions occur, or as 
services  are  provided  and  collectability  is  reasonably  assured.  In  certain  circumstances,  noninterest  income  is  reported  net  of 
associated  expenses  that  are  directly  related  to  variable  volume-based  sales  or  revenue  sharing  arrangements  or  when  the 
Company acts on an agency basis for others. 

Life Insurance Cash Surrender Value.  The Company has purchased life insurance policies on certain directors and officers as well 
as acquired such assets as part of the acquisition of other banks. Company owned life insurance is recorded at the amount that can 
be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other 
amounts due that are probable at settlement.  These assets are included in other assets on the consolidated balance sheets.

Intangible Assets. Intangible assets are comprised of goodwill, core deposit intangibles and other identifiable intangibles acquired 
in business combinations. Intangible assets with definite useful lives are amortized on an accelerated basis over their respective 
estimated useful lives not exceeding 15 years. If an event occurs that indicates the carrying amount of an intangible asset may not 
be  recoverable,  Management  reviews  the  asset  for  impairment.  Any  goodwill  and  any  intangible  asset  acquired  in  a  purchase 
business combination determined to have an indefinite useful life is not amortized, but is evaluated for impairment annually. The 
Company has the option to first assess qualitative factors to determine the likelihood of impairment pursuant to FASB ASU 2011-
08, Testing for Goodwill Impairment. Although the Company has the option to first assess qualitative factors when determining if 
impairment exists, the Company has opted to perform a quantitative analysis to determine if impairment exists. 

Impairment of  Long-Lived  Assets. The Company reviews  its long-lived and certain intangible assets for impairment  whenever 
events  or  changes  indicate  that  the  carrying  amount  of  an  asset  may  not  be  recoverable.  If  such  assets  are  considered  to  be 
impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair 
value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. 

Income  Taxes.  The  Company  and  its  subsidiaries  file  consolidated  tax  returns.  The  Company  accounts  for  income  taxes  in 
accordance  with  FASB  ASC  740,  Income  Taxes,  resulting  in  two  components  of  income  tax  expense:  current  and  deferred. 
Current income tax expense approximates taxes to be paid or refunded for the current period. The Company determines deferred 
income taxes using the balance sheet method. Under this method, the net deferred tax asset or liability is based on the tax effects 
of the differences between the book and tax bases of assets and liabilities, and recognizes enacted changes in tax rates and laws in 
the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between 
periods.  Deferred  tax  assets  are  recognized  subject  to  Management’s  judgment  that  realization  is  more  likely  than  not.  A  tax 
position that meets the more likely than not recognition threshold is measured to determine the amount of benefit to recognize. 
The  tax  position  is  measured  at  the  largest  amount  of  benefit  that  is  greater  than  fifty  percent  likely  of  being  realized  upon 
settlement. Interest and penalties are recognized as a component of income tax expense. 

Stock Options. The Company applies FASB ASC 718 – Compensation – Stock Compensation, to account for stock based awards 
granted  to  employees  using  the  fair  value  method.  The  Company  recognizes  compensation  expense  for  restricted  performance 
share  grants  over  the  relevant  attribution  period.  Restricted  performance  share  grants  have  no  exercise  price,  therefore,  the 
intrinsic  value  is  measured  using  an  estimated  per  share  price  at  the  vesting  date  for  each  restricted  performance  share.  The 
estimated  per  share  price  is  adjusted  during  the  attribution  period  to  reflect  actual  stock  price  performance.  The  Company’s 
obligation for unvested outstanding  restricted performance share grants is classified as a  liability until the vesting date due to a 
cash settlement feature, at which time the issued shares become classified as shareholders’ equity. 

Extinguishment  of  Debt.  Gains  and  losses,  including  fees,  incurred  in  connection  with  the  early  extinguishment  of  debt  are 
charged to current earnings as reductions in noninterest income. 

Postretirement Benefits. The Company uses an actuarial-based accrual method of accounting for post-retirement benefits. 

Other. Securities and other property held by the Bank in a fiduciary or agency capacity are not included in the financial statements 
since such items are not assets of the Company or its subsidiaries. 

Recently Adopted Accounting Standards 

In 2018, the Company adopted the following new accounting guidance: 

FASB Accounting Standard Update (ASU) 2014-09, Revenue (Topic 606): Revenue from Contracts with Customers, was issued 
May 2014. The ASU specifies a standardized approach for revenue recognition across industries and transactions. The ASU also 
requires  additional  disclosures.    The  scope  of  the  ASU  does  not  include  revenue  streams  covered  by  other  ASU  topics;  thus, 
Topic 606 does not apply to revenue related to financial instruments, guarantees and leases, which are the primary sources of the 
Company’s net interest income. 

All of the Company’s net interest income and a portion of its noninterest income are out of scope of the guidance. The contracts 
that are in scope of the guidance are primarily related to service charges and fees on deposit accounts, merchant processing fees, 
debit  card  fees,  ATM  processing  fees,  trust  fees  and  other  service  charges,  commissions  and  fees.  The  Company’s  revenue 
recognition practices within the scope of the ASU as described below did not change in any material regard upon adoption of the 
ASU.

Service Charges on Deposit Accounts, ATM Processing Fees and Other Service Fees: The Company earns fees from its deposit 
customers for transaction-based, account maintenance, and overdraft services.  Transaction-based fees are recognized at the time 
the transaction is executed as that is the point in time the  Company fulfills the customer’s request.  Account maintenance fees, 
which relate primarily to  monthly  maintenance, are earned over the course of a  month, representing the period over  which the 
Company  satisfies  the  performance  obligation.    Overdraft  fees  are  recognized  at  the  point  in  time  that  the  overdraft  occurs.  
Service charges on deposits are withdrawn from the customer’s account balance. ATM processing fees and other service fees are 
recognized at the point in time that the transaction occurs or the services provided. 

Merchant Processing Services and Debit Card Fees: The Company earns interchange fees from cardholder transactions conducted 
through  the  payment  networks.    Interchange  fees  from  cardholder  transactions  represent  a  percentage  of  the  underlying 
transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. 

Trust Fees: The Company earns trust fees from its contracts with customers to manage assets for investment or custody services.  
These fees are primarily earned over time as the Company provides the contracted monthly services and are generally assessed 
based on a tiered scale of the market value of assets under management (AUM) at month-end.  Other related services provided, 
which are based on a fixed fee schedule, are recognized when the services are rendered. 

Gains/Losses  on  Sales  of  OREO:    The  Company  records  a  gain  or  loss  from  the  sale  of  OREO  when  control  of  the  property 
transfers to the buyer, which generally occurs at the time of an executed deed.  The Company does not finance the sale of OREO. 
Gains on sale of OREO were $110 thousand, and $72 thousand and $1,185 thousand in the twelve months  ended December 31, 
2018 and 2017 and 2016, respectively. 

The Company adopted the ASU on January 1, 2018 and no cumulative adjustment was required. 

FASB ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and 
Financial Liabilities,  was issued January 2016.  The  ASU addresses certain aspects of  recognition,  measurement,  presentation, 
and disclosure of financial instruments. Most notably, the ASU changes the income statement impact of equity investments held 
by  the  Company  and  the  requirement  for  the  Company  to  use  the  exit  price  notion  when  measuring  the  fair  value  of  financial 
instruments for disclosure purposes (Note 11). 

The  Company  was  required  to  adopt  the  ASU  provisions  on  January  1,  2018,  and  for  those  equity  securities  with  readily 
determinable  fair  values,  the  Company  elected  the  retrospective  transition  approach  with  a  cumulative  effect  adjustment  to  the 
balance  sheet  and  for  those  equity  securities  that  do  not  have  readily  determinable  fair  values,  the  Company  elected  the 
prospective transition approach. The impact of the adoption of this accounting standard on the Company’s consolidated financial 
statements  will  be  subject  to  the  price  volatility  of  the  equity  investments.  As  a  result  of  implementing  the  ASU  provisions, 
effective January 1, 2018, the Company recorded a cumulative effect adjustment to decrease retained earnings by $142 thousand. 

FASB ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects 
from  Accumulated  Other  Comprehensive  Income,  was  issued  February  2018.    The  ASU  eliminates  the  stranded  tax  effects 
resulting from the Tax Cuts and Jobs Act of 2017 by allowing a reclassification from accumulated other comprehensive income to 
retained  earnings  for  stranded  tax  effects  resulting  from  the  Tax  Cuts  and  Jobs  Act  of  2017.   The  Company  early  adopted  the 
provisions of the ASU effective January 1, 2018, by reclassifying the Company’s $3,625 thousand stranded tax effect. 

Recently Issued Accounting Standards 

FASB ASU 2016-02, Leases (Topic 842), was issued February 25, 2016. The provisions of the new standard require lessees to 
recognize most leases on-balance sheet, increasing reported assets and liabilities. Lessor accounting remains substantially similar 
to current U.S. GAAP. 

The  Company  will  be  required  to  adopt  the  ASU  provisions  effective  January  1,  2019,  and  plans  to  elect  the  modified 
retrospective transition approach. The implementing entry will recognize a lease liability of $15.3 million and right-to-use asset of 
$15.3 million for facilities leases. The change in occupancy and equipment expense will not be material. 

FASB  ASU  2016-13,  Financial  Instruments  –  Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial 
Instruments,  was issued on June  16, 2016. The ASU significantly changes estimates  for credit losses related to financial assets 
measured at amortized cost and certain other contracts. For estimating credit losses, the FASB is replacing the incurred loss model 
with the current expected credit loss (CECL) model, which will accelerate recognition of credit losses.  Additionally, credit losses 
relating to debt securities available-for-sale will be recorded through an allowance for credit losses under the new standard. The

Company  will  also  be  required  to  provide  additional  disclosures  related  to  the  financial  assets  within  the  scope  of  the  new 
standard. 

The  Company  will  be  required  to  adopt  the  ASU  provisions  on  January  1,  2020.  Management  has  evaluated  available  data, 
defined  portfolio  segments  of  loans  with  similar  attributes,  and  selected  loss  estimate  models  for  each  identified  loan  portfolio 
segment. Management has preliminarily measured historical loss rates for each portfolio segment. The ultimate adjustment to the 
allowance for loan losses  will be accomplished through an offsetting after-tax adjustment to shareholders’ equity. Management 
has  also  segmented  debt  securities  held  to  maturity,  selected  methods  to  estimate  losses  for  each  segment,  and  preliminarily 
measured a loss estimate. Economic conditions and the composition of the Company’s loan portfolio  and debt securities held to 
maturity at the time of adoption will influence the extent of the adopting accounting adjustment. Management expects to develop 
an aggregate loss estimate by September 30, 2019. 

FASB  ASU  2017-08,  Receivables  –  Non-Refundable  Fees  and  Other  Costs  (Subtopic  310-20):  Premium  Amortization  on 
Purchased Callable Debt Securities, was issued March 2017. The ASU will shorten the amortization period for certain callable 
debt securities held at a premium. Specifically, the ASU requires the premium to be amortized to the earliest call date. The  ASU 
does not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. 
The Company will be required to adopt the ASU provisions on January 1, 2019. The implementing entry will reduce the carrying 
value  of  investment  securities,  specifically  obligations  of  states  and  political  subdivisions,  by  $3.1  million  and  reduce  retained 
earnings by $2.8 million, net of tax. The change in premium amortization method will not be material to revenue recognition. 

FASB ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, was 
issued August 2017.  The ASU will expand and refine hedge accounting for both nonfinancial and financial risk components and 
align the recognition and presentation of the effects of the  hedging instrument and the hedged item in the financial statements.  
The  ASU  also  provides  for  a  one-time  reclassification  of  prepayable  assets  from  held-to-maturity  (HTM)  to  available  for  sale 
(AFS) regardless of derivative use. 

The  Company  will  be  required  to  adopt  the  ASU  provisions  on  January  1,  2019.  The  Company  does  not  currently  engage  in 
trading activities or use derivative instruments to control interest rate risk, even though such activities may be permitted  with the 
approval of the Company’s Board of Directors. The Company has evaluated the prepayable assets in the HTM portfolio and will 
not effect a one-time reclassification of prepayable assets from HTM to the AFS upon implementation. 

FASB ASU 2018-13, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements 
for Fair Value Measurement, was issued August 2018.  The ASU is part of the disclosure framework project, where the primary 
focus is to improve the effectiveness of disclosures in the financial statements.  The ASU removes, modifies  and adds disclosure 
requirements related to Fair Value Measurements. 

The provisions of the ASU are effective January 1, 2020 with the option to early adopt any removed or modified disclosures upon 
issuance of the ASU.  The Company early adopted the provisions to remove and/or modify relevant disclosures in Note 11 to the 
consolidated financial statements.  The requirement to include additional disclosures will be adopted by the Company January  1, 
2020.  The additional disclosures will not affect the financial results upon adoption.

Note 2: Investment Securities 

Effective  January  1,  2018,  upon  adoption  of  ASU  2016-01,  equity  securities  included  in  the  Company’s  available  for  sale 
portfolio of $1,800 thousand were reclassified to equity securities. The reclassification of equity securities resulted in recording a 
cumulative effect adjustment to decrease retained earnings by $142 thousand, net of tax. 

At December 31, 2018, the market value of equity securities was $1,747 thousand. During the twelve  months ended December 
31, 2018, the Company recognized gross unrealized holding losses of $52 thousand in earnings. 

An analysis of the amortized cost and fair value by major categories of debt securities available for sale, which are carried at fair 
value with net unrealized gains (losses) reported on an after-tax basis as a component of cumulative other comprehensive income,

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. At December 31, 2018 and December 31, 2017, the Company 
had no high-risk collateralized mortgage obligations as defined by regulatory guidelines.

The  unrealized  losses  on  the  Company’s  debt  securities  were  caused  by  market  conditions  for  these  types  of  investments, 
particularly changes in risk-free interest rates. 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,  delinquency  and  loss  information  with  respect  to  the  underlying  collateral,  changes  in  the  levels  of 
subordination  for  the  Company’s  particular  position  within  the  repayment  structure  and  remaining  credit  enhancement  as 
compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a 
major rating agency. One corporate bond with a carrying value of $15.0 million and a market value of $13.8 million at December 
31, 2018, is rated below investment grade.  In addition to monitoring credit rating agency evaluations, Management performs its 
own evaluations regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities. 

The  Company  does  not  intend  to  sell  any  debt  securities  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. Therefore, the Company does not consider these 
debt securities to be other-than-temporarily impaired as of December 31, 2018. 

The  fair  values of  the debt securities could decline in the  future if the  general economy  deteriorates,  inflation increases, credit 
ratings  decline,  the  issuer’s  financial  condition  deteriorates,  or  the  liquidity  for  debt  securities  declines.  As  a  result,  other  than 
temporary impairments may occur in the future. 

As of December 31, 2018 and December 31, 2017, the Company had debt securities pledged to secure public deposits and short-
term borrowed funds of $728,161 thousand and $715,774 thousand, respectively.

The  Company’s  customers  are  small  businesses,  professionals  and  consumers.  Given  the  scale  of  these  borrowers,  corporate 
credit  rating  agencies  do  not  evaluate  the  borrowers’  financial  condition.  The  Company’s  subsidiary,  Westamerica  Bank  (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.”  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.

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 years 
ended  December  31,  2018,  2017  and  2016.  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 years ended December 31, 2018, 2017 and 2016 no such adjustments were recorded.

Note 8: Shareholders’ Equity 

The Company grants stock options and restricted performance shares to employees in exchange for employee services, pursuant 
to the  shareholder-approved  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,  2018, 2017 and 2016, the Company granted 249 thousand, 266 thousand and 325 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

The  weighted  average  estimated  grant  date  fair  value  for  options  granted  under  the  Company’s  stock  option  plan  during  the 
twelve months ended December 31, 2018, 2017 and 2016 was $9.98, $8.27 and $5.97 per share, respectively. The total remaining 
unrecognized  compensation  cost  related  to  nonvested  awards  as  of  December  31,  2018  is  $2,871  thousand  and  the  weighted 
average period over which the cost is expected to be recognized is 1.8 years. 

The total intrinsic value of options exercised during the twelve  months ended December 31,  2018,  2017 and 2016 was $4,264 
thousand, $4,642 thousand and $3,242 thousand, respectively. The total fair value of Restricted Performance Shares (“RPSs”) that 
vested  during  the  twelve  months  ended  December  31,  2018,  2017  and  2016  was  $1,143  thousand,  $708  thousand  and  $753 
thousand, respectively. The total fair value of options vested during the twelve months ended December 31, 2018, 2017 and 2016 
was $1,835 thousand,  $1,493 thousand and $1,269  thousand, respectively.  The Company adopted the  ASU  2016-09 provisions 
effective  January  1,  2017,  which  has  the  potential  to  create  volatility  in  the  book  tax  provision  at  the  time  nonqualified  stock 
options  are  exercised  or  expire.  During  the  twelve  months  of  2018,  292  thousand  shares  were  issued  due  to  the  exercise  of 
nonqualified stock options resulting in a tax deduction exceeding related share based compensation by $2,516 thousand. During 
the twelve months of 2017, 509 thousand shares were issued due to the exercise of nonqualified stock options resulting in a tax 
deduction exceeding related share based compensation by $1,667 thousand. The income tax provision was $737 thousand lower 
in 2018 and $698 thousand in 2017 lower than would have been under accounting standards prior to the adoption of ASU 2016-
09.  The  increase  in  tax  benefits  recognized  for  the  tax  deductions  from  the  exercise  of  options  totaled  $394  thousand  for  the 
twelve months ended December 31, 2016.

As of December 31, 2018 and 2017, the restricted performance shares had a weighted-average contractual life of 1.2 years. The 
compensation cost that was charged against income for the Company’s restricted performance shares granted was $660 thousand, 
$827 thousand and $1,228 thousand for the twelve months ended December 31, 2018, 2017 and 2016, respectively. There were 
no stock appreciation rights or incentive stock options granted in the twelve months ended December 31, 2018 and 2017. 

On February 13, 2009, the Company issued a warrant to purchase 246,640 shares of the Company’s common stock at an exercise 
price of $50.92 per share. The warrants may be exercised in a manner wherein the Company withholds shares of common stock 
issuable upon exercise of the warrant equal in value to the aggregate exercise price, in which case the warrant holder would not 
deliver cash for the aggregate exercise price and the Company would issue a number of shares equal to the intrinsic value on the 
exercise  date.  The  warrants  remain  outstanding  at  December  31, 2018.  On  January  29,  2019,  the  warrants  were  exercised  in  a 
cashless transaction resulting in the issuance of 50,788 shares of the Company’s common stock. 

The  Company  repurchases  and  retires  its  common  stock  in  accordance  with  Board  of  Directors  approved  share  repurchase 
programs. At December 31, 2018, approximately 1,750 thousand shares remained available to repurchase under such plans. 

Shareholders have authorized two additional classes of stock of one million shares each, to be denominated “Class B Common 
Stock”  and  “Preferred  Stock,”  respectively,  in  addition  to  the  150  million  shares  of  common  stock  presently  authorized.  At 
December 31, 2018, no shares of Class B Common Stock or Preferred Stock were outstanding. 

Note 9: Regulatory Capital  

Banks  and  bank  holding  companies  are  subject  to  regulatory  capital  requirements  administered  by  federal  banking  agencies. 
Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative  measures of 
assets,  liabilities,  and  certain  off-balance-sheet  items  calculated  under  regulatory  accounting  practices.  Capital  amounts  and 
classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory 
action.  The  final  rules  implementing  Basel  Committee  on  Banking  Supervision’s  capital  guidelines  for  U.S.  banks  (Basel  III 
rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in 
over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel III rules, the Company must hold a capital 
conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer was phased in from 
0.0% for 2015 to 2.50% in 2019. The capital conservation buffer was 1.875% for 2018 and 1.25% for 2017. The net unrealized 
gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of December 
31, 2018, 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 2018 and 2017, 
the  most  recent  regulatory  notifications  categorized  the  Bank  as  well  capitalized  under  the  regulatory  framework  for  prompt 
corrective  action.  There  are  no  conditions  or  events  since  that  notification  that  management  believes  have  changed  the 
institution’s category.

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. 

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

Deferred tax asset

Allowance for credit losses
State franchise taxes
AMT carryforward
Securities available for sale
Deferred compensation
Real estate owned
Purchased assets and assumed liabilities
Post-retirement benefits
Employee benefit accruals
VISA Class B shares
Limited partnership investments
Impaired capital assets

At December 31, 2018 and December 31, 2017, the Company had a $3,070 thousand and $3,056 thousand, respectively, deferred 
tax asset related to a California capital loss carryforwards which will expire if unutilized within five years of the year incurred. 
The  Company  believes  it  will  have  sufficient  California  capital  gains  within  the  five  year  utilization  period  to  absorb  the 
carryforward. 

At December 31, 2017, the Company had no net operating loss and a $1,752 thousand AMT tax credit carryforward; the AMT tax 
credit carryforward was fully utilized in 2018. 

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.

The 2017 income tax provision includes a $12.3 million dollar charge to re-measure the Company’s net deferred tax asset as a 
result of the enactment of the Tax Cuts and Jobs Act of 2017.  

A reconciliation of the beginning and ending amounts of unrecognized tax benefits follow:  

Balance at January 1,

Additions for tax positions taken in the current period
Reductions for tax positions taken in the current period
Additions for tax positions taken in prior years
Reductions for tax positions taken in prior years
Decrease related to settlements with taxing authorities
Decrease as a result of a lapse in statute of limitations

The  Company’s  uncertain  tax  positions  relate  to  positions  taken  on  tax  returns  which  are  under  examination.  The  timing  of 
concluding the examinations is dependent on the taxing authorities. The examinations could conclude in 2019.  Unrecognized tax 
benefits at December 31, 2018 and 2017 include accrued interest and penalties of $13 thousand and $13 thousand, respectively. 
When recognized, the entire amount of the unrecognized tax benefits will affect the effective tax rate.

The Company classifies interest and penalties as a component of the provision for income taxes. At December 31, 2018, the tax 
years ended December 31, 2017, 2016 and 2015 remain subject to examination by the Internal Revenue Service and the tax years 
ended December 31, 2017,  2016,  2015, 2014, 2013, 2012 and 2011 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.  Equity  securities  and  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, impaired loans, 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, asset-backed securities, and municipal bonds.  

Level  3  –  Valuation  is  generated  from  model-based  techniques  that  use  significant  assumptions  not  observable  in  the  market. 
These unobservable assumptions reflect the Company’s estimates of assumptions that market participants would use in pricing the 
asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.  

The Company relies on independent vendor pricing services to measure fair value for 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 conducts “other than temporary impairment (OTTI)” analysis on a quarterly basis; debt 
securities  selected  for  OTTI  analysis  include  all  debt  securities  at  a  market  price  below  95  percent  of  par  value.  As  with  any 
valuation technique used to estimate fair value, changes in underlying assumptions used could significantly affect the results of 
current and future values. Accordingly, these fair value estimates may not be realized in an actual sale of the securities. 

The  Company regularly reviews the valuation techniques and assumptions used by its vendors and determines  which valuation 
techniques  are  utilized  based  on  observable  market  inputs  for  the  type  of  securities  being  measured.  The  Company  uses  the 
information to determine the placement in the fair value hierarchy as level 1, 2 or 3.

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 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, 2018 and 
December 31, 2017, the following tables provide the level of valuation assumptions used to determine each adjustment and the 
carrying value of the related assets at period end.

Level 3 – Valuation is based upon present value of expected future cash flows, independent market prices, estimated liquidation 
values  of  loan  collateral  or  appraised  value  of  the  collateral  as  determined  by  third-party  independent  appraisers,  less  10%  for 
selling costs, generally. Level 3 includes other real estate owned that has been measured at fair value upon transfer to foreclosed 
assets  and  impaired  loans  collateralized  by  real  property  and  other  business  asset  collateral  where  a  specific  reserve  has  been 
established or a chargeoff has been recorded. Losses on other real estate owned represent losses recognized in earnings during the 
period subsequent to its initial classification as foreclosed assets. The unobservable inputs and qualitative information about the 
unobservable inputs are not presented as the inputs were not developed by the Company. 

Disclosures about Fair Value of Financial Instruments 

The  following  section  describes  the  valuation  methodologies  used  by  the  Company  for  estimating  fair  value  of  financial 
instruments not recorded at fair value in the balance sheet. The Company implemented the provisions of ASU 2016-01, Financial 
Instruments  –  Overall:  Recognition  and  Measurement  of  Financial  Assets  and  Financial  Liabilities,  effective  January  1,  2018. 
The  provisions  require  the  Company  to  use  the  “exit  price  notion”  when  measuring  the  fair  value  of  financial  instruments  for 
disclosure purposes.  

Cash  and  Due  from  Banks    Cash  and  due  from  banks  represent  U.S.  dollar  denominated  coin  and  currency,  deposits  at  the 
Federal  Reserve  Bank  and  correspondent  banks,  and  amounts  being  settled  with  other  banks  to  complete  the  processing  of  
customers’ daily transactions. Collectively, the Federal Reserve Bank and financial institutions operate in a market in which cash 
and  due  from  banks  transactions  are  processed  continuously  in  significant  daily  volumes  honoring  the  face  value  of  the  U.S. 
dollar. 

Equity Securities  The fair values of equity securities were estimated using quoted prices as describe above for Level 2 valuation. 

Debt Securities Held to Maturity  The fair values of debt securities were estimated using quoted prices as described above for 
Level 1 and Level 2 valuation. 

Loans  Loans are valued using the exit price notion. The Company uses a net present value of cash flows methodology that seeks 
to  incorporate  interest  rate,  credit,  liquidity  and  prepayment  risks  in  the  fair  market  value  estimation.  Inputs  to  the  calculation 
include  market  rates  for  similarly  offered  products,  market  interest  rate  projections,  credit  spreads,  estimated  credit  losses  and 
prepayment assumptions. 

Prior  to  adoption  of  ASU  2016-01,  loans  were  separated  into  two  groups  for  valuation.  Variable  rate  loans,  except  for  those 
described  below,  that  reprice  frequently  with  changes  in  market  rates  were  valued  using  historical  cost.  Fixed  rate  loans  and 
variable rate loans that have reached their minimum contractual interest rates were valued by discounting the future cash flows 
expected to be received from the loans using current interest rates charged on loans with similar characteristics. Additionally, the

allowance for loan losses of $23,009 thousand at December 31, 2017 was applied against the estimated fair values to recognize 
estimated future defaults of contractual cash flows. 

Deposit Liabilities  Deposits with no stated maturity such as checking accounts, savings accounts and money market accounts 
can be readily converted to cash or used to settle transactions at face value through the broad financial system operated by the 
Federal Reserve Banks and financial institutions. The fair value of deposits with no stated maturity is equal to the amount payable 
on  demand.  The  fair  value  of  time  deposits  was  estimated  using  a  net  present  value  of  cash  flows  methodology,  incorporating 
market interest rate projections and rates on alternative funding sources. 

Prior to adoption of ASU 2016-01, the fair value of time deposits were estimated by discounting estimated future contractual cash 
flows using current market rates for financial instruments with similar characteristics. 

Short-Term  Borrowed  Funds    The  carrying  amount  of  securities  sold  under  agreement  to  repurchase  and  other  short-term 
borrowed  funds  approximate  fair  value  due  to  the  relatively  short  period  of  time  between  their  origination  and  their  expected 
realization. 

The tables below are a summary of fair value estimates for financial instruments and the level of the fair value hierarchy within 
which the  fair value  measurements are categorized, excluding financial  instruments recorded at fair value on a recurring basis. 
The values assigned do not necessarily represent amounts which ultimately may be realized for assets or paid to settle liabilities. 
In addition, these values do not give effect to adjustments to fair value which may occur when financial instruments are sold or 
settled in larger quantities.  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 
other  assets  and  liabilities.  The  total  estimated  fair  values  do  not  represent,  and  should  not  be  construed  to  represent,  the 
underlying value of the Company.

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.

The total  minimum  future rental payments  have not been  reduced by  minimum  sublease  rentals of $1,319 thousand  due in  the 
future  under  noncancelable  subleases.  Total  rentals  for  premises  were  $6,794  thousand  in  2018,  $6,695  thousand  in  2017  and 
$6,823 thousand in 2016. Total sublease rentals were $397 thousand in 2018, $406 thousand in 2017 and $435 thousand in 2016. 
Total  rentals  for  premises,  net  of  sublease  income,  included  in  noninterest  expense  were  $6,397  thousand  in  2018,  $6,289 
thousand in 2017 and $6,388 thousand in 2016.  

Note 13: Commitments and Contingent Liabilities 

Loan  commitments  are  agreements  to  lend  to  a  customer  provided  there  is  no  violation  of  any  condition  established  in  the 
agreement. Commitments generally have fixed expiration dates or other termination clauses. Since many of the commitments are 
expected  to  expire  without  being  drawn  upon,  the  total  commitment  amounts  do  not  necessarily  represent  future  funding 
requirements. Loan commitments are subject to the Company’s normal credit policies and collateral requirements. Unfunded loan 
commitments  were  $278,598  thousand  and  $272,646  thousand  at  December  31,  2018  and  December  31,  2017,  respectively. 
Standby  letters  of  credit  commit  the  Company  to  make  payments  on  behalf  of  customers  when  certain  specified  future  events 
occur. Standby letters of credit are primarily issued to support customers’ short-term financing requirements and must meet the 
Company’s  normal  credit  policies  and  collateral  requirements.  Financial  and  performance  standby  letters  of  credit  outstanding 
totaled $2,772 thousand and $19,263 thousand at December 31, 2018 and December 31, 2017, respectively. The Company had no 
commitments  outstanding  for  commercial  and  similar  letters  of  credit  at  December  31,  2018  and  December  31,  2017.  The 
Company had $75 thousand in outstanding full recourse guarantees to a 3rd party credit card company at December 31, 2018. The 
Company  had  a  reserve  for  unfunded  commitments  of  $2,308  thousand  at  December  31,  2018  and  2017,  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. In the 
third quarter 2018, the Company achieved a  mediated settlement to dismiss a  lawsuit, subject to court approval, and accrued a 
liability for $3,500 thousand. 

The Company has determined that it will be obligated to provide refunds of revenue recognized in years prior to 2017 to some 
customers. The Company estimates the probable amount of these obligations will be $5,542 thousand and accrued a liability for 
such amount in 2017; the estimated liability is subject to revision.

Note 14: Retirement Benefit Plans 

The  Company  sponsors  a  qualified  defined  contribution  Deferred  Profit-Sharing  Plan  covering  substantially  all  of  its  salaried 
employees  with  one  or  more  years  of  service.  The  costs  charged  to  noninterest  expense  related  to  discretionary  Company 
contributions to the Deferred Profit-Sharing Plan were $1,057 thousand in 2018, $944 thousand in 2017 and $1,000 thousand in 
2016. 

The  Company  also  sponsors  a  qualified  defined  contribution  Tax  Deferred  Savings/Retirement  Plan  (ESOP)  covering  salaried 
employees  who  become  eligible  to  participate  upon  completion  of  a  90-day  introductory  period.  The  Tax  Deferred  Savings/ 
Retirement Plan (ESOP) allows employees to defer, on a pretax or after-tax basis, a portion of their salaries as contributions to 
this  Plan.  Participants  may  invest  in  several  funds,  including  one  fund  that  invests  primarily  in  Westamerica  Bancorporation 
common stock. The Company funds contributions to match participating employees’ contributions, subject to certain limits. The 
matching  contributions  charged  to  compensation  expense  were  $1,052  thousand  in  2018,  $1,098  thousand  in  2017  and  $1,075 
thousand in 2016. 

The Company offers a continuation of  group insurance coverage to  eligible employees  electing early retirement,  for  the period 
from  the  date  of  retirement  until  age  65.  For  eligible  employees  the  Company  pays  a  portion  of  these  early  retirees’  group 
insurance premiums. The Company also reimburses a portion of Medicare Part B premiums for all qualifying retirees over age 65 
and, if eligible, their spouses. Eligibility for post-retirement medical benefits is based on age and years of service, and restricted to 
employees hired prior to February 1, 2006 who elect early retirement prior to January 1, 2019. The Company uses an actuarial-
based  accrual  method  of  accounting  for  post-retirement  benefits.  The  Company  used  a  December  31  measurement  date  for 
determining post-retirement medical benefit calculations. 

The following tables set forth the net periodic post-retirement benefit cost and the change in the benefit obligation for the years 
ended December 31 and the funded status of the post-retirement benefit plan as of December 31:

The  above  discount  rate  is  based  on  the  Corporate  Aa  25-year  rate,  the  term  of  which  approximates  the  term  of  the  benefit 
obligations.  The  Company  reserves  the  right  to  terminate  or  alter  post-employment  health  benefits.  Post-retirement  medical 
benefits  are  currently  fixed  amounts  without  provision  for  future  increases;  as  a  result,  the  assumed  annual  average  rate  of 
inflation used to measure the expected cost of benefits covered by this program is zero percent for 2018 and beyond.

Payment of dividends to the Company by the Bank is limited under regulations for state chartered banks. The amount that can be 
paid  in  any  calendar  year,  without  prior  approval  from  regulatory  agencies,  cannot  exceed  the  net  profits  (as  defined)  for  the 
preceding  three  calendar  years  less  dividends  paid.  The  Company  consistently  has  paid  quarterly  dividends  to  its  shareholders 
since its formation in 1972. 

The Bank is required to  maintain reserves  with the Federal Reserve Bank equal to a  percentage  of its reservable deposits. The 
Bank’s daily average  on deposit at the  Federal Reserve Bank  was $473,250  thousand in 2018 and $458,186 thousand in 2017, 
which amounts exceed the Bank’s required reserves.

Note 18: Earnings Per Common Share  

The table below shows earnings per common share and diluted earnings per common share. Basic earnings per common share are 
computed by dividing net income by the average number of common shares outstanding during the period. Diluted earnings per 
common share are computed by dividing net income by the average number of common shares outstanding during the period plus 
the impact of common stock equivalents. 

Net income (numerator)
Basic earnings per common share
Weighted average number of common shares outstanding - basic (denominator)
Basic earnings per common share
Diluted earnings per common share
Weighted average number of common shares outstanding - basic
Add common stock equivalents for options
Weighted average number of common shares outstanding - diluted (denominator)
Diluted earnings per common share

For  the  years  ended  December  31,  2018,  2017  and  2016,  options  to  purchase  423  thousand,  323  thousand  and  773  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, 2018 and 2017, the related consolidated statements of income, comprehensive  income, changes in  shareholders’ 
equity, and cash flows for each of the years in the three-year period ended December 31, 2018, 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, 2018, 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, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the three-
year  period  ended  December  31,  2018  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, 2018, 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.

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, 2018. 

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,  2018  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
