PROXY STATEMENT 
March 12, 2018 
___________ 

GENERAL 

The Westamerica Board of Directors is soliciting proxies to be used at the 2018 Annual Meeting of Shareholders 
of Westamerica Bancorporation (the “Company”), which will be held at 10:00 a.m. Pacific Time, Thursday, April 
26,  2018,  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  12,  2018,  we  mailed  a  Notice  of 
Internet Availability of Proxy Materials (“Notice”) to certain of our shareholders. The Notice contains instructions 
about how to access our proxy materials and vote online or vote by telephone. If you would like to receive a paper 
copy  of  our  proxy  materials,  please  follow  the  instructions  included  in  the  Notice.  If  you  previously  chose  to 
receive our proxy materials electronically, you will continue to receive access to these materials via email unless 
you elect otherwise. 

Proof of Ownership May Be Required for Attending Annual Meeting in Person. You are entitled to attend 
the Annual Meeting only if you are a shareholder as of the close of business on February 26, 2018, the record date, 
or hold a valid proxy for the meeting. In order to be admitted to the  Annual Meeting, the Company reserves the 
right to request proof of ownership of Westamerica Bancorporation common stock on the record date. This can be: 
  A brokerage statement or letter from a bank or broker indicating ownership on February 26, 2018;  
  The Notice of Internet Availability of Proxy Materials; 
  A printout of proxy distribution email (if you received your materials electronically);  
  A Proxy Card; 
  A voting instruction form; or 
  A legal proxy provided by your broker, bank or nominee.  

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

Proxy Card. The Board has designated Arthur C. Latno, Jr., Ronald A. Nelson and Edward B. Sylvester to serve 
as  Proxies  for  the  Annual  Meeting.  As  Proxies,  they  will  vote  the  shares  represented  by  proxies  at  the  Annual 
Meeting. If you sign, date and return your Proxy Card but do not specify how to vote your shares, the Proxies will 
vote FOR the election of all of the Director nominees, FOR approval of the advisory vote on the compensation of 
our named executive officers, and  FOR ratifying the selection of independent auditor. The Proxies will also have

discretionary  authority  to  vote  in  accordance  with  their  judgment  on  any  other  matter  that  may  properly  come 
before the Annual Meeting that we did not have notice of by January 26, 2018. 

Quorum and Shares Outstanding. A quorum, which is a majority of the total shares outstanding as of the record 
date,  must  be  present  to  hold  the  Annual  Meeting.  A  quorum  is  calculated  based  on  the  number  of  shares 
represented  by  shareholders  attending  in  person  or  by  proxy.  On  February  26,  2018,  26,574,333  shares  of 
Westamerica  Bancorporation  common  stock  were  outstanding.  We  also  count  broker  non-votes,  which  we 
describe below, as shares present or represented at the Annual Meeting for the purpose of determining whether a 
quorum exists.  

Election of Director Nominees.  Each share is entitled to one vote, except in the election of Directors  where a 
shareholder  may  cumulate  votes  as  to  candidates  nominated  prior  to  voting,  but  only  when  a  shareholder  gives 
notice of intent to cumulate votes prior to the voting at the Annual Meeting. If any shareholder gives such notice, 
all  shareholders  may  cumulate  their  votes  for  nominees.  Under  cumulative  voting,  each  share  carries  as  many 
votes as the number of Directors to be elected, and the shareholder may cast all of such votes for a single nominee 
or  distribute  them  in  any  manner  among  as  many  nominees  as  desired.  This  Proxy  Statement  solicits  the 
discretionary  authority  to  cumulate  votes  and  allocate  them  in  the  Proxy  Holders’  discretion  if  any  shareholder 
requests cumulative voting. In the election of Directors, the nine nominees receiving the highest number of votes 
will be elected. If your proxy is marked “Withhold” with regard to the election of any nominee, your shares will be 
counted toward a quorum and for other nominees but they will not be voted for the election of that nominee. If you 
attend the Annual Meeting and have already voted, you may vote in person in order to rescind your previous vote.  

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

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

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

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

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

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

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

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

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

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

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

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

If  you  are  a  participant 

the  Westamerica  Bancorporation  Tax  Deferred 
in 
Voting  Deadlines. 
Savings/Retirement Plan (ESOP) your vote must be received by 11:59 p.m. Central Time, on April 23, 2018. 
All other shareholders voting by telephone or internet must vote by 12:01 a.m. Central Time, on April 26, 2018 
to ensure that their vote is counted.   

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

residing at the same address, unless such shareholders have notified their bank, broker, Computershare Investor

shares through Computershare Investor Services, contact Computershare toll-free at 877-588-4258 or in writing

Section 16(a) Beneficial Ownership Reporting Compliance 
Section 16(a) of the Securities and Exchange Act requires the Company’s Directors and Executive Officers and 
persons who own more than ten percent (10%) of a registered class of the Company’s equity securities to file 
reports of ownership and changes in ownership with the Securities and Exchange Commission. Our employees 
generally prepare these reports on the basis of information received from each Director and Officer. Based on 
the  review  of  copies  of  the  forms  filed,  the  Company  believes  that,  during  the  last  fiscal  year,  all  filing 
requirements under Section 16(a) applicable to its directors, officers, and 10% shareholders were filed timely, 
except for three reports filed one day delinquent for Messrs. Robinson, Sylvester and Thorson with respect to 
the  disposition  of  9,200,  1,260  and  2,000  shares,  respectively,  and  for  two  reports  filed  seventy-three  days 
delinquent for Messrs. Hansen and Schneck  with respect to the grant of  nonqualified stock options of 19,400 
and 5,900 shares, respectively, with one-third vesting on the first anniversary date of the grant date.

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,  A.C.  Latno,  Jr.,  P.D.  Lynch,  C.C.  MacMillan,  R.A.  Nelson,  and  E.B.  Sylvester  are 
“independent” Directors as defined in NASDAQ rules. 

Our Board has carefully considered the critical issue of Board leadership. In the context of risk management, the 
leadership  of  each  Board  committee  primarily  responsible  for  risk  management  is  vested  in  an  independent 
committee  chair.  With  regard  to  the  leadership  of  the  meetings  of  the  full  Board,  our  Board  of  Directors  has 
carefully evaluated whether the positions of chairman and CEO should be separate or combined. Our Board believes 
that the most effective leadership structure for the Company at this time is to combine the responsibilities of the 
Chairman and CEO, a structure that has been successful since 1989. The combined positions avoid a duplication of 
efforts, enable decisive leadership, ensure a clear accountability for the performance of the Company, a more rapid 
implementation of decisions, and a consistent vision. Given the size of our employee base and our level of assets 
relative  to  larger,  more  complex  banking  structures,  our  Company  is  particularly  well  suited  to  combine  the 
Chairman and CEO functions. Furthermore, our management team has an average tenure of 23 years and does not 
require the substantial oversight needed by a less experienced team, which has allowed our Chairman and CEO to 
lead the Company through eleven acquisitions since 1992.  

To  ensure  strong  Board  oversight  eight  of  our  nine  Directors  are,  as  noted  above,  independent  as  defined  by 
NASDAQ.  Only  non-management  directors  sit  on  Board  committees,  with  the  exception  of  the  Executive 
Committee,  and  every  non-management  director  sits  on  one  or  more  of  these  Committees.  All  non-management 
directors meet at least four times a year outside the presence of the Chairman and CEO. The Board completes an 
annual board evaluation that is discussed by the Nominating Committee and presented to the full Board. 

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

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

the independent Directors; 

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

communication. 

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

The Board of Directors of the Company also serve as the Board of Directors of Westamerica Bank, and as such are 
well  informed  of  Bank  operations  through  regular  reports  and  discussions  on  the  operations  of  the  Bank.  The 
Directors’ longevity with the Company has exposed them to a wide range of business cycles, which plays a critical 
role in managing the risk profile and profitability of the Company through the current economic environment. 

Role of the Board of Directors in Risk Oversight 

The Board is also responsible for overseeing all aspects of management of the Company, including risk oversight, 
which is effected through all Board committees, but primarily through the Board’s Audit Committee.  The Internal

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 is attached as Exhibit A to the Proxy Statement for this 
2018 Annual Meeting of Shareholders. 

Employee Benefits and Compensation Committee 

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

Functions: The Compensation Committee administers Westamerica Bancorporation’s 2012 Amended and Restated 
Stock  Option  Plan  of  1995,  Tax  Deferred  Savings  and  Retirement  Plan,  Deferred  Profit  Sharing  Plan,  Deferred 
Compensation  Plan,  and  the  Westamerica  Bancorporation  Deferral  Plan.  It  administers  the  Company’s 
compensation  programs  and  reviews  and  reports  to  the  Board  the  compensation  level  for  executive  officers, 
including  the  CEO,  of  the  Company  and  its  subsidiaries  and  determines  that  compensation  plans  are  balanced 
between  financial  results  and  prudent  risk  taking.  The  Compensation  Committee  determines  annual  corporate 
performance  objectives  for  equity  compensation  and  cash  bonuses  and  their  related  corporate,  divisional  and 
individual goals. Based on the CEO’s assessment of the extent to which each executive officer met those objectives 
and  goals,  the  Committee  determines  each  executive  officer’s  annual  equity  compensation  and  cash  bonus.  The 
Compensation Committee also establishes the individual goals and targets for the CEO. All compensation approved 
by  the  Compensation  Committee  is  reported  to  the  full  Board  of  Directors.  The  role  of  the  Compensation 
Committee is described in greater detail under the section entitled “Compensation Discussion and Analysis.” 

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

Nominating Committee 

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

Functions: The Nominating Committee screens and recommends qualified candidates for Board membership. This 
Committee  recommends  a  slate  of  nominees  for  each  Annual  Meeting.  As  part  of  that  process,  it  evaluates  and 
considers all candidates submitted by shareholders in accordance with the Company’s Bylaws, and considers each 
existing  Board  member’s  contributions.  The  Committee  applies  the  same  evaluation  standards  whether  the 
candidate was recommended by a shareholder or the Board. The Nominating Committee is governed by a written 
charter,  which  was  reaffirmed  January  27,  2016  and  attached  as  Exhibit  B  to  the  Proxy  Statement  for  the  2016 
Annual Meeting of Shareholders. 

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

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

Nominations must include the following information: 

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

the nominee; 

  The name and address of the nominating shareholder; and 
  The number of shares of capital stock of the Company owned by the nominating shareholder. 

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; 
  Ability to approach problems objectively, rationally and realistically; 
  Ability to respond well and to function under pressure; 
  Willingness to respect the confidences of the Board and the Company; 
  Willingness to devote the time necessary to function effectively as a Board member; 
  Possess independence necessary to make unbiased evaluation of Management performance;

(1) Non-employee Directors did not receive options or stock awards. During 2017, 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 2017 and in previous years. 

Westamerica Bancorporation does not have a charitable donations program for Directors nor does it make donations 
on  behalf  of  any  Director(s).  The  Company  may  make  a  nominal  donation  through  its  Community  Relations 
program to non-profit organizations where a Director(s) may have an affiliation.

and principal accounting officer. 

Compensation Discussion and Analysis  

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

The  Compensation  Committee  governs  the  executive  compensation  program  that  combines  three  compensation 
elements:  base  salary,  annual  non-equity  cash  incentives,  and  long-term  stock  grants.  Several  compensation 
philosophies and practices underlie this program: 

  Base salaries for participants in this program should be limited to foster an environment where incentive 

compensation motivates and rewards corporate, divisional, and individual performance. 

  Incentive  compensation  (annual  non-equity  cash  incentives  and  long-term  stock  grants)  is  based  on 
measurement of performance against pre-established objective measurable goals. Specific criteria for each 
objective are established for “threshold,” “target,” and “outstanding” performance. On any one measure, 
performance below “threshold” results in no credit for that objective. “Threshold” performance results in 
75%  achievement,  “target”  performance  results  in  100%  achievement,  and  “outstanding”  performance 
results  in  150%  achievement.  The  performance  achievement  level  determines  the  size  of  incentive 
compensation awards. 

  Long-term incentive stock grants will be awarded to senior management if the corporate performance level 

is rated “threshold” or better. The purpose of long-term incentive grants is to: 

(1) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018.

–  Motivate senior management to focus on long-term performance; 
–  Avoid excessive risk-taking and instill conservative management practices; 
–  Build equity ownership among Westamerica’s senior management; 
–  Link shareholder interests to management incentives; and 
–  Create ownership mentality among senior management. 

In  February  2013,  the  Board  of  Directors  adopted  a  clawback  policy  that  requires  executive  officers  to  forfeit 
previously  awarded  incentive  compensation  if  the  incentives  were  based  on  materially  inaccurate  financial 
statements or other performance measures that are later proven to be materially inaccurate or the  achievement of 
which were due to fraud or other misconduct. 

Establishing Incentive Levels, Determining Objectives and Measuring Performance 

In administering the executive compensation program, the Compensation Committee determines “target” incentives 
for each position annually. The Compensation Committee exercises discretion in establishing “target” incentives in 
an  effort  to  provide  competitive  pay  practices  while  motivating  and  rewarding  performance  that  benefits  the 
Company’s long-term financial performance and shareholder interests, and avoids excessive risk-taking. 

At  the  beginning  of  each  calendar  year,  the  Compensation  Committee  establishes  annual  corporate  performance 
objectives. In establishing corporate performance objectives, the Compensation Committee takes into consideration 
the current operating environment for the commercial banking industry as well as internal management policies and 
practices which would, in the Compensation Committee’s opinion, benefit the long-term interests of the Company 
and  its  shareholders.  Corporate  performance  measures  include  risk  management  elements  considered  to  be 
responsive  to  the  impact  that  current  operating  conditions  could  have  on  the  long-term  performance  of  the 
Company. The Compensation Committee monitors the economy and the banking industry’s operating environment 
throughout the ensuing year, and may exercise discretion in adjusting corporate performance objectives during the 
year. 

The operating environment for the commercial banking industry is impacted by a myriad of factors including, but 
not limited to, local, national and global economic conditions, interest rate levels and trends, monetary policies of 
the Federal Reserve Board and its counterparts in other countries, fiscal policies of the United States government 
and other global political conditions, regulations and legislation, liquidity in capital markets, the demand for capital 
by  commercial  enterprises  and  consumers,  new  financial  products,  competitive  response  to  changing  conditions 
within the industry, trade balances, the changing values of real estate, currencies, commodities and other assets, and 
other factors. 

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

Restricted performance shares (“RPS”) represent awards of Westamerica Bancorporation’s common stock subject 
to achievement of performance objectives established by the Compensation Committee. The 2012 Amended and 
Restated Stock Option Plan of 1995 (the “2012 Amended Plan”), which was originally approved by shareholders in

1995, and amended with shareholder approval in 2003 and again in 2012, defines the performance factors the Board 
must use in administering RPS grants as one or more of the following: earnings, diluted earnings per share, revenue 
and revenue per diluted share, expenses, share price, return on equity, return on equity relative to the average return 
on equity for similarly sized institutions, return on assets, return on assets relative to the average return on assets for 
similarly sized institutions, efficiency ratio (operating expenses divided by operating revenues), net loan losses as a 
percentage of average loans outstanding, nonperforming assets, and nonperforming assets as a percentage of total 
assets.  

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

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

Stock Grants 

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

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

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

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

extend the term or approve a new stock option plan. 

The 2012 Amended Plan allows four types of stock-based compensation awards: 

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

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

Stock Appreciation Rights (“SAR”)  provide  the  holder  a  cash  payment  equal  to  the  difference  between  the  fair 
market value of the Westamerica Bancorporation’s common stock on the date the SAR is surrendered and the fair 
market  value  of  the  Company’s  common  stock  on  the  date  the  SAR  was  granted.  The  optionee  incurs  taxable

income at the time the SAR is settled and the Company receives a corporate tax deduction in the same amount. 

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

Determination of Awards to Grant 

In determining which type of stock-based compensation awards to grant, the Compensation Committee considers 
the attributes of each form of incentive. Examples include the ability to motivate management to make decisions 
based on the long-term interests of shareholders, the desire to compensate with shares rather than cash, and the tax 
consequences  of  each  type  of  award.  The  Compensation  Committee  retains  the  latitude  to  utilize  all  forms  of 
incentives  provided  under  the  2012  Amended  Plan.  In  the  current  and  preceding  years,  the  Compensation 
Committee has utilized NQSO and RPS based on the motivational aspects of stock price appreciation, the settlement 
in shares rather than cash, and the preservation of tax deductions for the Company. As of February 26, 2018, the 
Company had no ISO or SAR awards outstanding. 

Determination of Option Exercise Price 

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

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

Long-Term Incentive Attributes 

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

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

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

Compensation for the Chairman, President & CEO 

Mr.  Payne  performs  two  functions  for  the  Company.  These  two  functions  tend  to  be  compensated  separately  at 
similarly  sized  banking  institutions.  Mr.  Payne  serves  as  Chairman  of  the  Board  and  CEO  with  responsibilities 
including  oversight  of  the  organization  and  external  strategic  initiatives.  Mr.  Payne  also  serves  as  President  and 
CEO  with  responsibilities  including  daily  management  of  internal  operations.  Mr.  Payne’s  total  compensation 
reflects these broad responsibilities. Consistent with the overall compensation philosophy for senior executives, Mr. 
Payne’s compensation has a greater amount of pay at risk through incentives than through base salary. Since Mr. 
Payne is compensated as an executive, he is not eligible to receive compensation as a Director. 

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

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

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

Compensation Awarded to Named Executive Officers 

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

"Target"
Cash
Incentive

X

Composite Corporate,
Divisional and Individual
Performance Level

In structuring performance goals for the named executive officers, the Compensation Committee emphasizes goals, 
which if achieved, will benefit the overall Company. As such, senior management level positions have high relative 
weighting on corporate objectives, and divisional leadership positions also have significant weighting on divisional 
objectives.  The  “target”  cash  incentive  and  the  weighting  of  goals  for  the  named  executive  officers  for  2017 
performance were as follows:

The Compensation Committee establishes corporate goals with the intent to balance current profitability with long-
term stability of the Company and its future earnings potential. The 2017 corporate performance goals related to 
current  year  “profitability”  included  return  on  equity,  return  on  assets  and  diluted  earnings  per  share.  The 
performance  goals  designed  to  maintain  the  long-term  stability  of  the  Company  include  “quality”  and  “control” 
components. The “quality” measures include loan portfolio quality measures (originated classified loans and other 
real estate owned, originated non-performing loans and originated other real estate owned, and net loan losses to 
average originated loans) and service quality  measures (external service quality to customers and internal service 
quality  of  support  departments  and  branches).  The  “control”  measures  include  non-interest  expense  to  revenues 
(efficiency  ratio),  the  level  of  non-interest  expenses,  and  internal  audit  results.  By  maintaining  both  current  year 
“profitability”  goals  and  longer-term  “quality”  and  “control”  goals,  Management  has  a  disincentive  to  maximize 
current earnings at the expense of longer-term results.  

For  2017,  the  Compensation  Committee  expected  nominal  economic  growth  with  an  uncertain  interest  rate 
environment., As a result, the Committee reserved the ability to exercise a certain degree of judgment in adjusting 
target goals based on the resulting operating environment. 

The Compensation Committee determined the 2017 operating environment was generally characterized as follows: 

  Growth in the United States’ economy increased slightly from the prior year, but growth was tempered; 
  Inflation remained below targets established by the Federal Open Market Committee in spite of continuing 

monetary policy accommodation and improving employment conditions; 

  The Federal Open Market Committee increased the federal funds rate on three occasions resulting in rising 
short-term interest rates; however, intermediate term interest rates did not begin to increase until late in the 
year; 

  Throughout most of 2017, competitive interest rates on loans remained below the yields required for the 

Company to deliver satisfactory financial results throughout a full business cycle; 

  Interest rates on investment securities remained relatively low compared to interest rates which would exist 

with moderated monetary policies and economic conditions; 

  Real estate values in the Company’s metropolitan geographies appeared to increase to levels above those 

which could be sustained by prevailing economic conditions; and 

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

increased operational risks. 

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

  Management maintained discipline in pricing loans for long-term financial results; 
  Management consistently maintained conservative loan underwriting practices to appropriately manage the 

Company’s exposure to credit risk;

  Management  avoided  higher-yielding  longer-dated  investment  securities,  maintaining  an  appropriately 
short duration bond portfolio to provide asset re-pricing opportunities in a rising interest rate environment;  
  Management  increased  the  value  of  the  Company’s  deposit  base  by  increasing  checking  and  savings 

deposits and reducing time deposits; 

  Management reduced operating costs to offset market interest rate pressure on revenues; 
  Management maintained high levels of customer service; and 
  Management prudently managed capital enabling the Company to continue delivering increasing annual 

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

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

In reviewing the operating environment, Management’s response to the operating environment, and adjusted results 
compared  to  “target”  performance  goals,  the  Compensation  Committee  determined  corporate  performance  to  be 
110.5% of target goals. 

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

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

  Manage the Company to achievement of financial goals including return on equity, return on assets, and 

earnings per share; 

  Maintain and improve credit quality in a manner prudent for the final stages of an economic expansion; 
  Achieving budgeted deposit growth goals;  
  Stabilizing loan volumes; 
  Satisfactory regulatory examinations and external and internal audit results;

RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved 
over  the  three-year  period.  In  January  2018,  the  Compensation  Committee  evaluated  whether  the  three  year 
corporate performance objectives were met for RPS awards granted in January 2015. The performance objectives 
for the RPS granted in January 2015 included: 

  3 year cumulative diluted earnings per share (EPS);

  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

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 2015 vested upon achievement of three year goals. 

Nonqualified Deferred Compensation Programs 

The Company maintains nonqualified deferred compensation programs to provide senior and mid-level executives 
the  ability  to  defer  compensation  in  excess  of  the  annual  limits  imposed  on  the  Company’s  ESOP  plan.  The 
Company  believes  these  tax  deferral  programs  enhance  loyalty  and  motivate  retention  of  executives.  These 
programs allow executives to defer cash pay and RPS shares upon vesting. The programs also allow Directors to 
defer Director fees. 

  Cash pay deferred in the program accumulates in accounts in the names of the participating Directors and 
executives.  The  Company  credits  the  balance  of  these  accounts  with  interest  using  an  interest  rate  that 
approximates  the  crediting  rate  on  corporate-owned  life  insurance  policies,  under  which  Directors  and 
executives  are  the  named  insured.  Deferrals  and  interest  credits  represent  general  obligations  of  the 
Company. 

  The common stock the Company issues to executives upon the vesting of RPS grants may be deferred into 
the  program  and  deposited  into  a  “Rabbi  Trust.”  Since  these  shares  are  outstanding  shares  of  the 
Company’s  common  stock,  the  Company  pays  dividends  on  these  shares  at  the  same  rate  paid  to  all 
shareholders. The shares held in the “Rabbi Trust” are subject to claims by the Company’s creditors. 

Employment Contracts 

None of the executives named in the accompanying tables have employment contracts with the Company. 

Compensation in the Event of a Change in Control  

The  banking  industry  has  significant  merger  and  acquisition  activity.  To  promote  retention  of  senior  executives, 
unvested NQSO and RPS grants contain a “change in control” provision, which trigger full vesting upon a change in 
control. The Compensation Committee determined these provisions were appropriate in order to retain executives to 
continue managing the Company after any “change in control” was announced through its ultimate consummation. 
Since none of the named executive officers have entered employment contracts with the Company, they serve in an

“at-will” capacity and could terminate their employment at any time. The Compensation Committee felt it would be 
in the best interests of shareholders to have a retention mechanism in place to provide continuity of management 
during  a  “change  in  control”  process.  Further,  the  Committee  expects  the  named  executive  officers  would  be 
terminated by an acquiring institution rather than retained in a similar functional capacity. 

The Company also maintains a Severance Payment Plan covering all employees to promote employee retention. 
The Severance Payment Plan provides salary continuation benefits for employees in the event of a “change in 
control.” The amount of salary continuation benefits  is based on years of service and corporate title, but in no 
event exceed the equivalent of one times annual salary. All named executive officers are eligible for one year’s 
salary under the plan. 

Other  

Internal  Revenue  Code  (“IRC”)  Section  162(m)  places  a  limit  on  the  amount  of  compensation  that  may  be 
deducted by the Company in any year with respect to certain of the Company’s highest-paid executives. Prior to 
enactment of the Tax Cuts and Jobs Act of 2017 (the “Act”), certain “performance-based compensation”  was 
not  counted  toward  this  limit.  The  Act  eliminated  the  “performance-based  compensation”  exemption.  The 
Company intends generally to qualify compensation paid to executive officers for deductibility under the IRC 
but reserves the right to pay compensation that is not deductible. 

Employee Benefits Compensation Committee Report 

We, the Compensation Committee of the Board of Directors of the Company, have reviewed and discussed the 
Compensation  Discussion  and  Analysis  with  Management.  Based  on  that  review  and  discussion,  we  have 
recommended to the Board of Directors inclusion of the Compensation Discussion and Analysis in this Proxy 
Statement and the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Compensation Committee Interlocks and Insider Participation 

No member of the Compensation Committee is a current or former officer or employee of the Company or any 
of  its  subsidiaries,  or  entered  into  (or  agreed  to  enter  into)  any  transaction  or  series  of  transactions  with  the 
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. 

Summary Compensation 

The following table sets forth summary compensation information for the chief executive officer, chief financial 
officer  and  each  of  the  other  three  most  highly  compensated  executive  officers  for  the  fiscal  years  ending 
December  31, 2017,  2016,  and  2015. These  persons  are  referred  to  as  named  executive  officers  elsewhere  in

(1)  Stock  Awards  represent  RPS  shares  as  described  in  the  Compensation  Discussion  &  Analysis.  The  amounts  shown  represent  the 
aggregate grant date fair market value.   
 (2)  Option  awards  represent  Nonqualified  Stock  Options  as  described  in  the  Compensation  Discussion  &  Analysis.  The  amounts  shown 
represent the aggregate grant date fair market value.   
(3) The amounts shown are non-equity incentive compensation only. No interest or other form of earnings was paid on the compensation. 
(4) The amounts include interest paid on deferred cash compensation to the extent the interest exceeds 120% of the long-term Applicable 
Federal  Rates  with  compounding.  The  Company  has  no  defined  benefit  pension  plan.  Mr.  Payne  has  a  pension  agreement,  which  is 
discussed under “Pension Benefits for Fiscal Year 2017.” 
(5)  Each  of the  above-named  executive  officers  received  less  than $10,000  of  aggregate  perquisites  and personal  benefits,  except  for  Mr. 
Hansen who received a car allowance of $12,000. All other compensation includes Company contributions to defined contribution plans 
(ESOP  and  Deferred  Profit  Sharing),  and  amounts  added  to  taxable  wages  using  IRS  tables  for  the  cost  of  providing  group  term  life 
insurance coverage that is more than the cost of $50,000 of coverage. It also includes the dollar value of the benefit to Mr. Payne for the 
portion of the premium payable by the Company with respect to a split dollar life insurance policy (projected on an actuarial basis), and a 
bonus paid to Mr. Payne in the amount of his portion of the split dollar life insurance premium. 
(6) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. 
(7) Mr. Rizzardi's compensation is subject to garnishments and liens pursuant to certain domestic relations orders. 

Based  on  the  compensation  disclosed  in  the  Summary  Compensation  Table,  approximately  32%  of  total 
compensation comes from base salaries. See Compensation Discussion and Analysis for more details. 

Pay Ratio Disclosure 

In August 2015 pursuant to a mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the 
Securities  and  Exchange  Commission  adopted  a  rule  requiring  annual  disclosure  of  the  ratio  of  the  median 
employee’s  annual  total  compensation  to  the  total  annual  compensation  of  the  principal  executive  officer 
(“PEO”). The Company’s PEO is Mr. Payne.

In  determining  the  median  employee  total  annual  compensation,  the  Company  prepared  a  census  of  all 
employees as of December 31, 2017,  who  were  employed  for the full  2017 calendar  year. For simplicity, the 
value of benefits provided by the Company’s qualified retirement plans and welfare benefit plans were excluded 
from the determination of total annual compensation as all employees are offered the same benefit programs.

Non-Qualified Pension Agreement

$4,861,948

$511,950

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

The discount rate used to determine the present value is 3.99%. The obligation is an unfunded general obligation 
of the Company.

(1) No RPS shares were deferred upon vesting in 2017.  Non-equity incentive plan compensation deferred in 2017 was earned in 2016 and 
disclosed as compensation in the Summary Compensation Table for 2016 and is therefore excluded from the Summary Compensation Table 
for Fiscal Year 2017.  
(2)  Includes  change  in  value  of  deferred  RPS  shares,  dividends  earned  on  deferred  RPS  shares,  and  interest  earned  on  deferred  cash 
compensation.    The  amounts  included  in  the  Summary  Compensation  Table  for  Fiscal  Year  2017  on  page  27  are  as  follows:    Messrs. 
Thorson - $42,431; Robinson - $36,094; Hansen - $28,092. 
(3) Includes dividends paid on deferred RPS shares. 
(4)  Aggregate  balance  of  deferred  compensation  reported  as  compensation  prior  to  2017  is  as  follows:    Messrs.  Thorson  -  $1,854,512; 
Robinson - $2,783,960; Hansen - $2,154,514.  
(5) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. 

Under  the  Westamerica  Bancorporation  and  Subsidiaries  Deferred  Compensation  Plan  (the  “Deferred 
Compensation  Plan”),  Directors  and  Officers  may  defer  up  to  100%  of  their  Director’s  compensation,  salary 
and/or non-equity incentive compensation (cash bonus) into a non-qualified, unfunded deferred compensation 
program. The interest rate paid during  2017  was 5.0%. The interest rate  may be  changed annually. Interest is 
compounded  semi-monthly.  Participants  choose  in  advance  from  the  following  distribution  commencement 
dates: termination of employment,  January 1 following termination of employment,  or a specific date  at least 
five years from date of deferral. Payment is made in a lump sum unless the participant chooses a four year, five 
year or ten year annual installment. 

Under the Westamerica Bancorporation Deferral Plan, 100% of vested RPS grants may be deferred. Dividends 
paid on such issued and outstanding shares are paid in cash to the deferral participants, and are paid at the same

rate as is paid to all other shareholders. The distribution of deferred RPS shares occurs at least two years after 
deferral, one month following termination, or the January 1 immediately following termination as elected by the 
participant at the time of deferral. If the participant is one of the named executive officers, benefit distributions 
that  are  made  upon  termination  of  employment  may  not  start  earlier  than  six  months  after  the  date  of 
termination. 

Potential Payments Upon Termination or Change in Control 

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

Termination 

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

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

Change in Control 

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

In the event of a change in control, unvested NQSOs and RPS shares immediately vest. The value of in-the-money 
options and RPS shares subject to accelerated vesting for each of the named executive officers is as follows: Messrs. 
Payne:  $0; Thorson: $991,902;  Robinson(1): $997,399;  Hansen:  $892,637;  and  Rizzardi(2) $804,217. The  value  is 
computed by multiplying the difference between the market value on December 29, 2017, the last business day of 
2017, and the exercise price of each option by the number of shares subject to accelerated vesting. 

Under the Company’s Severance Payment Plan, executive officers receive six week’s pay for every year or partial 
year of service up to one year’s base salary (see Summary Compensation Table for Fiscal Year 2017 for annual 
base salary for all named executive officers). All named executive officers have met the service requirement for 
one  year’s  base  salary.  Severance  pay  is  paid  in  a  lump  sum  or  on  a  semi-monthly  basis  at  the  discretion of the 
Company. The Severance Payment Plan is subject to Section 409A of the Internal Revenue Code. 

(1) Mr. Robinson retired from the position of Banking Division Manager of Westamerica Bank effective January 31, 2018. 
(2) Mr. Rizzardi’s compensation is subject to garnishments and liens pursuant to certain domestic relations orders.

Certain Relationships and Related Party Transactions 

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

Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries of 
the Company in the ordinary course of business. With the exception of the Company’s Employee Loan Program, all 
outstanding  loans  and  commitments  included  in  such  transactions  were  made  on  substantially  the  same  terms, 
including  interest  rates  and  collateral,  as  those  prevailing  at  the  time  for  comparable  transactions  with  other 
persons not related to the Company, did not involve more than a normal risk of collectability, and did not present 
other favorable features. As part of the Employee Loan Program, all employees, including executive officers, are 
eligible  to  receive  mortgage  loans  with  interest  rates  one  percent  (1%)  below  Westamerica  Bank’s  prevailing 
interest  rate  at  the  time  of  loan  origination.  Westamerica  Bank  makes  all  loans  to  executive  officers  under  the 
Employee Loan Program in compliance with the applicable restrictions of Section 22(h) of the Federal Reserve Act. 
Messrs. Payne, Thorson, and Hansen have mortgage loans through this Program. The largest aggregate amount of 
principal during  2017  was  $384,877,  $267,611, and  $214,079,  respectively.  The principal  amount  outstanding  at 
December 31, 2017 was $367,495, $254,253, and $0, respectively. The amount of principal paid during 2017 was 
$17,382, $13,358, and $214,079, respectively. The amount  of interest paid during  2017 was $8,825, $6,215, and 
$825, respectively. The rate of interest payable on the loans is 2.875%, 3.125%, and 0%, respectively.  

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

Background 

The 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) requires that 
shareholders  cast  a  non-binding  advisory  vote  on  the  executive  compensation  paid  to  the  executive  officers 
listed  in  the  Summary  Compensation  Table  (a  so-called  “say  on  pay”  vote)  as  well  as  an  advisory  vote  with 
respect  to  whether  future  say  on  pay  votes  will  be  held  every  one,  two  or  three  years.  The  result  of  the 
shareholder  vote  on  the  proposal  to  determine  the  frequency  of  future  say  on  pay  proposals  was  that 
shareholders should review executive compensation annually. Therefore, Proposal 2 requests that shareholders 
again approve the compensation paid to our named executive officers. Last  year 99% of the shares voting on 
this  proposal  voted  to  support  our  Corporation’s  executive  compensation  strategy.  The  proposal  to  determine 
how often the say on pay proposal should be voted on by shareholders will again be brought to a shareholder 
vote in 2022.  

We  believe  that our compensation policies and procedures are centered on a pay-for-performance culture and 
are strongly aligned with the long-term interests of our shareholders. Our incentive compensation plan provides 
for  the  grant  of  incentive  stock  options,  non-qualified  stock  options,  stock  appreciation  rights,  and  restricted 
performance  shares.  The  Summary  Compensation  Table  shows  very  stable  base  salaries  indicative  of  our 
greater emphasis on performance-based stock and non-stock awards. Our stock and option awards are based on 
a minimum achievement of meeting the “threshold” level for each pre-established objective. Both awards have 
a  three-year  vesting  period.  Our  annual  incentive  plan  incorporates  at  least  four  financial  and/or  strategic

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 – RATIFY SELECTION OF INDEPENDENT AUDITOR   

Ratify Selection of Independent Auditor 

Action  by  the  shareholders  is  not  required  by  law  in  the  appointment  of  independent  auditors,  but  their 
appointment is submitted by the Audit Committee and the Board of Directors in order to give the shareholders 
an opportunity to present their views. If the proposal is approved, the Audit Committee, in its discretion, may 
direct the appointment of different independent auditors at any time during the year if it determines that such a 
change would be in the best interests of the Company and its shareholders. If the proposal to ratify the selection 
of Crowe Horwath LLP as the Company’s independent auditors is rejected by the shareholders, then the Audit 
Committee  will  reconsider  its  choice  of  independent  auditors.  A  representative  of  Crowe  Horwath  LLP  is 
expected to be present at the Annual Meeting and will have an opportunity to make a statement if they so desire 
and will be available to respond to appropriate questions.  

Audit Fees 

The aggregate fees billed to the Company by Crowe Horwath LLP with respect to services performed for fiscal 
2017 and 2016 are as follows:

consolidated financial statements, reviews of the consolidated financial statements included in the Company’s quarterly reports on Form 10-
Q,  and  the  audit  of  the  Company’s  internal  controls  over  financial  reporting.  The  audit  fees  also  relate  to  services  such  as consents  and 
audits of mortgage banking subsidiaries. 
(2) Audit-related fees consisted of fees billed by Crowe Horwath LLP for audits of certain employee benefits plans. 
(3) Tax fees consisted of fees billed by Crowe Horwath LLP for the compilation and review of the Company’s tax returns.  

Preapproval Policies and Procedures 

The Audit Committee is responsible for the appointment, compensation, retention and oversight of the work of 
any public accounting firm engaged by the Company for the purpose of preparing or issuing an audit report or 
performing  other  audit,  review  or  attest  services  for  the  Company.  Any  accounting  firm  appointed  by  the 
Company reports directly to the Audit Committee. 

The Audit Committee must preapprove all auditing services and permitted non-audit services by its independent 
auditors and the fees to be paid by the Company for these services, except for those fees qualifying for the “de 
minimis  exception”  which  provides  that  the  preapproval  requirement  for  certain  non-audit  services  may  be 
waived if certain express standards and requirements are satisfied prior to completion of the audit under certain 
conditions. This exception requires that the aggregate amount of all such services provided constitutes no more 
than five percent of the total amount of revenue paid to the audit firm by the Company during the fiscal year in 
which the services are provided. This exception also requires that at the time of the engagement, the Company 
did not recognize such services to be non-audit services, and such services are promptly brought to the attention

fiscal year 2017, there were no non-audit services that were provided using this exception. 

The  Audit  Committee  may  delegate  to  one  or  more  members  of  the  Audit  Committee  the  authority  to  grant 
preapprovals  of  non-audit  services  and  fees.  In  such  event,  the  decisions  of  the  member  or  members  of  the 
Committee  regarding  preapprovals  are  presented  to  the  full  Audit  Committee  at  its  next  meeting.  The  Audit 
Committee  preapproved  100%  of  all  services  performed  on  behalf  of  the  Company  by  Crowe  Horwath  LLP 
during fiscal year 2017.  

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

AUDIT COMMITTEE REPORT 

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

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

In performing its functions, the Audit Committee acts only in an oversight capacity and necessarily relies on the 
work  and  assurances  of  the  Company’s  management,  which  has  the  primary  responsibility  for  financial 
statements and reports, and of the independent auditors. The auditors express an opinion on the conformity of 
the  Company’s  annual  financial  statements  to  United  States  generally  accepted  accounting  principles  and  on 
internal  control  over  financial  reporting.  In  fulfilling  its  oversight  responsibilities,  the  Audit  Committee 
reviewed  the  audited  consolidated  financial  statements  for  the  fiscal  year  2017  and  discussed  them  with 
Management and with Crowe Horwath, LLP, the Corporation’s independent registered public accountants. 

Management  represented  to  the  Audit  Committee  that  the  Company’s  consolidated  financial  statements  were 
prepared  in  accordance  with  generally  accepted  accounting  principles.  Management  also  represented  that  it 
performed  an  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting  as  of  December  31, 
2017, and that internal control over financial reporting  was effective. The  independent auditor discussed  with 
the Audit Committee matters required to be discussed by Auditing Standard of the Public Accounting Oversight 
Board (PCAOB), including certain matters related to the conduct of an audit and to obtain certain information 
from the Audit Committee relevant to the audit. 

The auditors also provided to the Audit Committee the written disclosures and the letter from the independent 
auditors required by PCAOB standards. The Audit Committee discussed with auditors the firm’s independence. 

Based  on  the  Audit  Committee’s  discussion  with  Management  and  the  independent  auditors,  the  Audit 
Committee’s review of the representations of Management and the  Report of the Independent  Auditors to the 
Audit  Committee,  the  Audit  Committee  recommended  that  the  Board  of  Directors  include  the  audited 
consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 
31, 2017 for filing with the SEC.

2M, P.O. Box 1200, Suisun City, CA 94585, no  later than 5:00 p.m. on  November 12, 2018. However, if 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 25, 2019, for the 2019 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 25, 2019. 

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:

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

EXHIBIT A 
Westamerica Bancorporation 
Audit Committee Charter – Updated and Reaffirmed January 24, 2018 

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

While the Audit Committee has the responsibilities and powers set forth in this Charter, it is not the duty of the 
Audit Committee to plan or conduct audits, or to determine that the Company’s financial statements are complete 
and  accurate  and  are  in  accordance  with  generally  accepted  accounting  principles.  This  is  the  responsibility  of 
management and the independent auditor. 

The function of the Audit Committee is oversight. Management is responsible for the preparation and integrity of 
the  Company’s  financial  statements.  Management  is  responsible  for  maintaining  appropriate  accounting  and 
financial  reporting  policies  and  an  appropriate  internal  control  environment.  Subject  to  appointment,  review  and 
oversight by the Audit Committee, the independent auditor is responsible for planning and conducting a proper audit 
of  the  Company’s  internal  control  environment  and  of  its  annual  financial  statements,  reviewing  the  Company’s 
quarterly financial statements prior to the filing of each quarterly report on Form 10-Q, and other procedures. 

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

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

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

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

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

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

The Audit Committee shall make regular reports to the Board. 

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

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

be taken into consideration as part of this review. 

20.  Receive  and  review  a  report  from  each  independent  auditor at  least  annually  regarding  the  independent 
auditor’s  independence  and  discuss  such  reports  with  the  auditor.  Ensure  that  each  independent  auditor 
submits  a  formal  written  statement,  as  required  by  PCAOB  Rule  3526,  as  it  may  be  amended  or 
supplemented, describing all relationships between the independent auditor and any of its affiliates and the 
Company that might bear on the independent auditor’s independence. The independent auditor must also 
discuss  with  the  Audit  Committee  the  potential  effects  of  any  such  relationships  on  the  firm’s 
independence. Receive and review a formal written statement of the fees billed by the independent auditor 
for each of the categories of services requiring separate disclosure in the annual proxy statement.  

21.  Obtain  and  review  a  report  from  each  independent  auditor  at  least  annually  regarding  the  independent

governmental  or  professional  authorities  within  the  preceding  five  years  respecting  one  or  more 
independent audits carried out by the firm, and any steps taken to deal with any such issues. Obtain auditor 
and review inspection reports issued by the PCAOB under Section 104 of the Sarbanes-Oxley Act. 

22.  Meet with each independent auditor prior to the audit to review the planning and staffing of the audit. 

23.  Advise the Board of its determinations regarding the qualification, independence and performance of each 

independent auditor. 

24.  Annually  require  the  independent  auditor  to  confirm  in  writing  its  understanding  of  the  fact  that  it  is 

ultimately accountable to the Audit Committee. 

25.  Require  the  independent  auditor  to  rotate  every  five  years  the  lead  audit  partner  in  charge  of  the 

Company’s audit and the concurring audit partner responsible for reviewing the audit. 

26.  Periodically  consider  the  advisability  of  rotating  the  independent  audit  firm  to  be  selected  as  the 
Company’s independent auditors. The Audit Committee should present its conclusions to the full Board.

Committee  discovers  that  a  material  fraud  has  occurred,  the  Audit  Committee  shall  (i)  assess  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

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 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,  2017,  the  Company  had  consolidated  assets  of  approximately  $5.5  billion,  deposits  of  approximately  $4.8 
billion  and  shareholders’  equity  of  approximately  $590  million.  The  Company  and  its  subsidiaries  employed  785  full-time 
equivalent staff as of December 31, 2017. 

The Company’s Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments 
to  those  reports  as  well  as  beneficial  ownership  reports  on  Forms  3,  4  and  5  are  available  through  the  SEC’s  website 
(https://www.sec.gov). Such documents as well as the Company’s director, officer and employee Code of Conduct and Ethics are 
also available free of charge from the Company by request to:

Supervision and Regulation 

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

Regulation and Supervision of Bank Holding Companies  

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

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

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

The FRB generally prohibits a bank holding company from declaring or paying a cash dividend that would impose undue pressure 
on the capital of subsidiary banks or would be funded only through borrowing or other arrangements which might adversely affect 
a bank holding company’s financial position. Under the FRB policy, a bank holding company should not continue its existing rate

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,  2017,  the  Company’s  and  the  Bank’s  respective  ratios  exceeded  applicable  regulatory  requirements.  See 
Note  9 to the consolidated  financial statements  for capital ratios of the Company and the  Bank, compared to  minimum capital 
requirements and for the Bank the standards for well capitalized depository institutions. 

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

See  the  sections  entitled  “Capital  Resources  and  Capital  to  Risk-Adjusted  Assets”  in  Item  7,  Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations for additional information. 

Prompt Corrective Action and Other Enforcement Mechanisms  

FDICIA  requires  each  federal  banking  agency  to  take  prompt  corrective  action  to  resolve  the  problems  of  insured  depository 
institutions, including but not limited to those that fall below one or more prescribed minimum capital ratios. 

An institution that, based upon its capital levels, is classified as “well capitalized,” “adequately capitalized” or “undercapitalized” 
may be treated as though it  were  in the  next lower capital category if the appropriate  federal banking agency, after  notice and 
opportunity for hearing, determines that an unsafe or unsound condition or an unsafe or unsound practice warrants such treatment. 
At each successive lower capital category, an insured depository institution is subject to more restrictions. In addition to measures 
taken under the prompt corrective action provisions, commercial banking organizations may be subject to potential enforcement 
actions by the  federal banking agencies  for unsafe or unsound practices in conducting their businesses or for  violations of any 
law, rule, regulation or any condition imposed in writing by the agency or any written agreement with the agency. 

Safety and Soundness Standards  

FDICIA  has  implemented  certain  specific  restrictions  on  transactions  and  required  federal  banking  regulators  to  adopt  overall 
safety and soundness standards for depository institutions related to internal control, loan underwriting and documentation, and 
asset growth. Among other things, FDICIA limits the interest rates paid on deposits by undercapitalized institutions, restricts the 
use  of  brokered  deposits,  limits  the  aggregate  extensions  of  credit  by  a  depository  institution  to  an  executive  officer,  director, 
principal  shareholder  or  related  interest,  and  reduces  deposit  insurance  coverage  for  deposits  offered  by  undercapitalized 
institutions for deposits by certain employee benefits accounts. The federal banking agencies may require an institution to submit 
an acceptable compliance plan as well as have the flexibility to pursue other more appropriate or effective courses of action given 
the specific circumstances and severity of an institution’s noncompliance with one or more standards. 

Federal banking agencies require banks to maintain adequate valuation allowances for potential credit losses. The Company has 
an  internal  staff  that  continually  reviews  loan  quality  and  reports  to  the  Board  of  Directors.  This  analysis  includes  a  detailed 
review of the classification and categorization of problem loans, assessment of the overall quality and collectability of the loan 
portfolio,  consideration  of  loan  loss  experience,  trends  in  problem  loans,  concentration  of  credit  risk,  and  current  economic 
conditions,  particularly  in  the  Bank’s  market  areas.  Based  on  this  analysis,  Management,  with  the  review  and  approval  of  the 
Board, determines the adequate level of allowance required. The allowance is allocated to different segments of the loan portfolio, 
but the entire allowance is available for the loan portfolio in its entirety. 

Restrictions on Dividends and Other Distributions 

The  Company’s  ability  to  pay  dividends  to  its  shareholders  is  subject  to  the  restrictions  set  forth  in  the  California  General 
Corporation  Law  (“CGCL”).  The  CGCL  provides  that  a  corporation  may  make  a  distribution  to  its  shareholders  if  (i)  the 
corporation’s retained earnings equal or exceed the amount of the proposed distribution plus unpaid accrued dividends (if any) on 
securities  with a dividend preference, or (ii)  immediately after the dividend, the corporation’s total assets equal or exceed total 
liabilities plus unpaid accrued dividends (if any) on securities with a dividend preference. 

The  power  of  the  board  of  directors  of  an  insured  depository  institution  to  declare  a  cash  dividend  or  other  distribution  with 
respect  to  capital  is  subject  to  statutory  and  regulatory  restrictions  which  limit  the  amount  available  for  such  distribution 
depending upon the earnings, financial condition and cash needs of the institution, as well as general business conditions. FDICIA 
prohibits  insured  depository  institutions  from  paying  management  fees  to  any  controlling  persons  or,  with  certain  limited 
exceptions, making capital distributions, including dividends, if, after such transaction, the institution would be undercapitalized. 

In  addition  to  the  restrictions  imposed  under  federal  law,  banks  chartered  under  California  law  generally  may  only  pay  cash 
dividends to the extent such payments do not exceed the lesser of retained earnings of the bank or the bank’s net income for  its 
last three fiscal years (less any distributions to shareholders during this period). In the event a bank desires to pay cash dividends 
in  excess  of  such  amount,  the  bank  may  pay  a  cash  dividend  with  the  prior  approval  of  the  Commissioner  in  an  amount  not 
exceeding the greatest of the bank’s retained earnings, the bank’s net income for its last fiscal year or the bank’s net income for its 
current fiscal year. 

The federal banking agencies also have the authority to prohibit a depository institution or its holding company from engaging in 
business  practices  which  are  considered  to  be  unsafe  or  unsound,  possibly  including  payment  of  dividends  or  other  payments 
under certain circumstances even if such payments are not expressly prohibited by statute. The Federal reserve Board has issued

guidance indicating its expectations that a bank holding company will inform and consult with Federal Reserve supervisory staff 
sufficiently in advance of (i) declaring and paying a dividend that could raise safety and soundness concerns (e.g., declaring and 
paying  a  dividend  that  exceeds  earnings  for  the  period  for  which  the  dividend  is  being  paid);  (ii)  redeeming  or  repurchasing 
regulatory  capital  instruments  when  the  bank  holding  company  is  experiencing  financial  weaknesses;  or  (iii)  redeeming  or 
repurchasing common stock or perpetual preferred stock that would result in a net reduction as of the end of the quarter in the 
amount of such equity instruments outstanding compared with the beginning of the quarter in which the redemption or repurchase 
occurred. 

Premiums for Deposit Insurance 

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

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

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

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

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

tangible equity as required by the Dodd-Frank Act; 

(2)  Change the deposit insurance assessment rates (which sets forth progressively lower assessment rate schedules that 

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

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

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

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

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

regular assessments; and  

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

pursuant to an FDIC final rule issued April, 2016. 

The Company cannot provide any assurance as to the effect of any future changes in its deposit insurance premium rates. 

Community Reinvestment Act and Fair Lending Developments 

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

Financial Privacy Legislation and Customer Information Security  

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

U.S.A. PATRIOT Act  

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

Sarbanes-Oxley Act of 2002  

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

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

Programs To Mitigate Identity Theft 

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

respond  appropriately  to  red  flags  that  are  detected;  and  (iv)  ensure  that  the  program  is  updated  periodically  as  appropriate  to 
address  changing  circumstances.  The  regulations  include  guidelines  that  each  institution  must  consider  and,  to  the  extent 
appropriate, include in its program. 

Pending Legislation  

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

Competition  

In the past, the Bank’s principal competitors for deposits and loans have been major banks and smaller community banks, savings 
and loan associations and credit unions. To a lesser extent, competition was also provided by thrift and loans, mortgage brokerage 
companies and insurance companies. Other institutions, such as brokerage houses, mutual fund companies, credit card companies, 
and  certain  retail  establishments  have  offered  investment  vehicles  that  also  compete  with  banks  for  deposit  business.  Federal 
legislation in recent years has encouraged competition between different types of financial institutions and fostered new entrants 
into the financial services market. 

Legislative changes, as well as technological and economic factors, can be expected to have an ongoing impact on competitive 
conditions  within  the  financial  services  industry.  While  the  future  impact  of  regulatory  and  legislative  changes  cannot  be 
predicted with certainty, the business of banking will remain highly competitive. 

ITEM 1A. RISK FACTORS  

Readers and prospective investors in the Company’s securities should carefully consider the following risk factors as well as the 
other information contained or incorporated by reference in this Report. 

The  risks  and  uncertainties  described  below  are  not  the  only  ones  facing  the  Company.  Additional  risks  and  uncertainties  that 
Management  is  not  aware  of  or  focused  on  or  that  Management  currently  deems  immaterial  may  also  impair  the  Company’s 
business operations. This Report is qualified in its entirety by these risk factors. 

If any of the following risks actually occur, the Company’s financial condition and results of operations could be materially and 
adversely affected. If this were to happen, the value of the company’s securities could decline significantly, and investors  could 
lose all or part of their investment in the Company’s common stock. 

Market and Interest Rate Risk  

Changes in interest rates could reduce income and cash flow.  

The  discussion  in  this  Report  under  “Item  7  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of 
Operations  –  Asset,  Liability  and  Market  Risk  Management”  and  “-  Liquidity  and  Funding”  and  “Item  7A  Quantitative  and 
Qualitative Disclosures About Market Risk” is incorporated by reference in this paragraph. The Company’s income and cash flow 
depend to a great extent on the difference between the interest earned on loans and investment securities and the interest paid on 
deposits and other borrowings, and the Company’s success in competing for loans and deposits. The Company cannot control or 
prevent changes in the level of interest rates which fluctuate in response to general economic conditions, the policies of various 
governmental and regulatory agencies, in particular, the Federal Open Market Committee of the FRB, and pricing practices of the 
Company’s competitors. Changes in monetary policy, including changes in interest rates, will influence the origination of loans, 
the  purchase  of  investments,  the  generation  of  deposits  and  other  borrowings,  and  the  rates  received  on  loans  and  investment 
securities and paid on deposits and other liabilities.

Changes in capital market conditions could reduce asset valuations.  

Capital  market  conditions,  including  liquidity,  investor  confidence,  bond  issuer  credit  worthiness,  perceived  counter-party  risk, 
the supply of and demand for financial instruments, the financial strength of market participants, and other factors  can materially 
impact the value of the Company’s assets. An impairment in the value of the Company’s assets could result in asset write-downs, 
reducing the Company’s asset values, earnings, and equity. 

The value of securities in the Company’s investment securities portfolio may be negatively affected by disruptions in securities 
markets 

The  market  for  some  of  the  investment  securities  held  in  the  Company’s  portfolio  can  be  extremely  volatile.  Volatile  market 
conditions  may  detrimentally  affect  the  value  of  these  securities,  such  as  through  reduced  valuations  due  to  the  perception  of 
heightened  credit  and  liquidity  risks.  There  can  be  no  assurance  that  the  declines  in  market  value  will  not  result  in  other  than 
temporary  impairments  of  these  assets,  which  would  lead  to  loss  recognition  that  could  have  a  material  adverse  effect  on  the 
Company’s net income and capital levels. 

The weakness of other financial institutions could adversely affect the Company.  

Financial services institutions are interrelated as a result of trading, clearing, counterparty, or other relationships.   The Company 
routinely executes transactions with counterparties in the financial services industry, including brokers and dealers, commercial 
banks, investment banks, and other institutional clients. Many of these transactions expose the Company to credit risk in the event 
of default of the Company’s counterparty or client. In addition, the Company’s credit risk may be increased when the collateral 
the Company holds cannot be realized or is liquidated at prices not sufficient to recover the full amount of the secured obligation. 
There  is  no  assurance  that  any  such  losses  would  not  materially  and  adversely  affect  the  Company’s  results  of  operations  or 
earnings.  

Shares of Company common stock eligible for future sale or grant of stock options could have a dilutive effect on the market 
for Company common stock and could adversely affect the market price. 

The Articles of Incorporation of the Company authorize the issuance of 150 million shares of common stock (and two additional 
classes  of  1  million  shares  each,  denominated  “Class  B  Common  Stock”  and  “Preferred  Stock”,  respectively)  of  which 
approximately 26.4 million shares of common stock were outstanding at December 31, 2017. Pursuant to its stock option plans, at 
December 31, 2017, the Company had outstanding options for 1.0 million shares of common stock, of which 469 thousand were 
currently exercisable. As of December 31, 2017, 930 thousand shares of Company common stock remained available for grants 
under  the  Company’s  stock  option  plans.  Sales  of  substantial  amounts  of  Company  common  stock  in  the  public  market  could 
adversely affect the market price of its common stock.  

The Company’s payment of dividends on common stock could be eliminated or reduced. 

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

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

The  Company  repurchases  and  retires  its  common  stock  in  accordance  with  Board  of  Directors-approved  share  repurchase 
programs.  At  December  31,  2017,  approximately  1.8  million  shares  remained  available  to  repurchase  under  such  plans.  The 
Company has been active in repurchasing and retiring shares of its common stock when alternative uses of excess capital, such as 
acquisitions, have been limited. The Company could repurchase shares of its common stock at price levels considered excessive, 
thereby spending more cash on such repurchases as deemed reasonable and effectively retiring fewer shares than would be retired 
if repurchases were effected at lower prices. 

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

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

The Company can provide no assurance that the credit quality of the loan portfolio will not deteriorate in the future and that such 
deterioration will not adversely affect the Company.

The  Company’s  operations  are  concentrated  geographically  in  California,  and  poor  economic  conditions  may  cause  the 
Company to incur losses. 

Substantially all of the Company’s business is located in California. A portion of the loan portfolio of the Company is dependent 
on real estate. At December 31, 2017, real estate served as the principal source of collateral with respect to approximately 53% of 
the Company’s loan portfolio. The Company’s financial condition and operating results will be subject to changes in economic 
conditions in California. The California economy was severely affected by the recessionary period of 2008 to 2009. Much of the 
California  real  estate  market  experienced  a  decline  in  values  of  varying  degrees.  This  decline  had  an  adverse  impact  on  the 
business of some of the Company’s borrowers and on the value of the collateral for many of the Company’s loans. Generally, the 
counties  surrounding  and  near  San  Francisco  Bay  have  recovered  more  soundly  from  the  recent  recession  than  counties  in  the 
California  “Central  Valley,”  from  Sacramento  in  the  north  to  Bakersfield  in  the  south.  Approximately  22%  of  the  Company’s 
loans are to borrowers in the California “Central Valley.” Economic conditions in California’s diverse geographic markets can be 
vastly  different  and  are  subject  to  various  uncertainties,  including  the  condition  of  the  construction  and  real  estate  sectors,  the 
effect  of  drought  on  the  agricultural  sector  and  its  infrastructure,  and  the  California  state  government’s  budgetary  and  fiscal 
condition. The Company can provide no assurance that conditions in any sector or geographic market of the California economy 
will not deteriorate in the future and that such deterioration will not adversely affect the Company. 

The markets in which the Company operates are subject to the risk of earthquakes, fire storms and other natural disasters. 

All  of  the  properties  of  the  Company  are  located  in  California.  Also,  most  of  the  real  and  personal  properties  which  currently 
secure  a  majority  of  the  Company’s  loans  are  located  in  California.  Further,  the  Company  invests  in  securities  issued  by 
companies  and  municipalities  operating  throughout  the  United  States,  and  in  mortgage-backed  securities  collateralized  by  real 
property located throughout the United States.  California and other regions of the United States are prone to earthquakes, brush 
and  forest  fires,  flooding,  drought  and  other  natural  disasters.  In  addition  to  possibly  sustaining  uninsured  damage  to  its  own 
properties, if there is a major earthquake, flood, drought, fire or other natural disaster, the Company faces the risk that many of its 
debtors  may  experience  uninsured  property  losses,  or  sustained  business  or  employment  interruption  and/or  loss  which  may 
materially impair their ability to meet the terms of their  debt obligations. A major earthquake, flood,  prolonged drought, fire or 
other natural disaster in California or other regions of the United States could have a material adverse effect on the Company’s 
business, financial condition, results of operations and cash flows. 

Adverse changes in general business or economic conditions could have a material adverse effect on the Company’s financial 
condition and results of operations.  

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

 
 
 
 
 
 

 
 
 

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

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

The Company’s financial performance generally, and in particular the ability of borrowers to pay interest on and repay principal 
of outstanding loans and the value of collateral securing those loans, are highly dependent upon the business environment in the

markets  where  the  Company  operates,  in  the  State  of  California  and  in  the  United  States  as  a  whole.  A  favorable  business 
environment  is  generally  characterized  by,  among  other  factors,  economic  growth,  healthy  labor  markets,  efficient  capital 
markets, low inflation, high business and investor confidence, and strong business earnings. Unfavorable or uncertain economic 
and  market  conditions  can  be  caused  by:  declines  in  economic  growth,  high  rates  of  unemployment,  deflation,  declines  in 
business activity or consumer, investor or business confidence; limitations on the availability of or increases in the cost of credit 
and capital; increases in inflation; natural disasters; or a combination of these or other factors. 

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

Regulatory Risks 

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

As  a  holding  company,  a  substantial  portion  of  the  Company’s  cash  flow  typically  comes  from  dividends  paid  by  the  Bank. 
Various  statutory  provisions  restrict  the  amount  of  dividends  the  Company’s  subsidiaries  can  pay  to  the  Company  without 
regulatory approval. The Bank obtained regulatory approval for dividends paid to the Company in 2017. A reduction in subsidiary 
dividends paid to the Company could limit the capacity of the Company to pay dividends.  In addition, if any of the Company’s 
subsidiaries were to liquidate, that subsidiary’s creditors will be entitled to receive distributions from the assets of that subsidiary 
to satisfy their claims against it before the Company, as a holder of an equity interest in the subsidiary, will be entitled to receive 
any of the assets of the subsidiary. 

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

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

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

Additionally, the Company’s business is affected significantly by the fiscal and  monetary policies of the federal government and 
its agencies. The Company is particularly affected by the policies of the FRB, which regulates the supply of money and credit in 
the United States of America. Among the instruments of monetary policy available to the FRB are (a)  conducting open market 
operations in U.S. government securities, (b) changing the discount rates of borrowings by depository institutions,  (c) changing 
interest  rates  paid  on  balances  financial  institutions  deposit  with  the  FRB,  and  (d)  imposing  or  changing  reserve  requirements 
against certain borrowings by banks and their affiliates. These methods are used in varying degrees and combinations to directly 
affect the availability of bank loans and deposits, as well as the interest rates charged on loans and paid on deposits. The policies 
of  the  FRB  may  have  a  material  effect  on  the  Company’s  business,  results  of  operations  and  financial  condition.  Under  long- 
standing policy of the FRB, a BHC is expected to act as a source of financial strength for its subsidiary banks. As a result of that 
policy, the Company may be required to commit financial and other resources to its subsidiary bank in circumstances where the 
Company might not otherwise do so. 

Following the most recent recession, the FRB has been providing vast amounts of liquidity into the banking system. The FRB has 
been  purchasing  large  quantities  of  U.S.  government  securities,  including  agency-backed  mortgage  securities,  increasing  the 
demand for such securities thereby reducing interest rates.  The FRB began reducing these asset purchase activities in the fourth 
quarter 2013 and the Federal Open Market Committee (“FOMC”) has been increasing the target range for the federal funds rate. 
On December 13, 2017, the FOMC raised the target range for the  federal funds rate  to 1¼  to  1½ percent,  which could reduce 
liquidity in the markets and cause interest rates to rise, thereby increasing funding costs to the Bank, reducing the availability of 
funds to the Bank to finance its existing operations, and causing fixed-rate investment securities and loans to decline in value.

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

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

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

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

Systems, Accounting and Internal Control Risks  

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

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

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

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

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

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

ITEM 2. PROPERTIES  

Branch Offices and Facilities  

Westamerica  Bank  is  engaged  in  the  banking  business  through  82  branch  offices  in  21  counties  in  Northern  and  Central 
California. WAB believes all of its offices are constructed and equipped to meet prescribed security requirements. 

The Company owns 29 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  

Neither  the  Company  nor  any  of  its  subsidiaries  is  a  party  to  any  material  pending  legal  proceeding,  nor  is  their  property  the 
subject of any material pending legal proceeding, other than ordinary routine legal proceedings arising in the ordinary course of 
the Company’s business. None of these proceedings is expected to have a material adverse impact upon the Company’s business, 
financial position or results of operations.

As of January 31, 2018, there were approximately 5,700 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 47 through 88, 
as well as with the other information presented throughout this Report. 

Critical Accounting Policies 

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

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

Net Income  

The Company reported net income of $50.0 million and diluted earnings per common share (“EPS”) of $1.89 in 2017. The 2017 
results include adjustments to net deferred tax asset values triggered by enactment of the Tax Cuts and Jobs Act of 2017 which 
reduced EPS $0.48, recognition of a loss contingency which reduced EPS $0.12, and securities gains which increased EPS $0.18. 
The 2017 results compare to net income of $58.9 million or $2.29 EPS for the year ended December 31, 2016 and net income of 
$58.8 million or $2.30 EPS for the year ended December 31, 2015. 

The Company’s principal source of revenue is net interest and loan fee income, which represents interest and fees earned on loans 
and  investment  securities  (“earning  assets”)  reduced  by  interest  paid  on  deposits  and  other  borrowings  (“interest-bearing 
liabilities”).  Market  interest  rates  declined  considerably  following  the  recession  of  2008  and  2009.  Interest  rates  remained 
historically low through 2016 as the Federal Open Market Committee’s (“FOMC”) monetary policy was highly accommodative. 
During this period, Management avoided originating long-dated, low-yielding loans given the potential impact of such assets on 
forward  earning  potential;  as  a  result,  loans  declined  and  investment  securities  increased.  The  changing  composition  of  the 
earning assets and low market interest rates has pressured the net interest margin to lower levels. The FOMC’s first post-recession 
increase in the federal funds rate occurred in December 2015, although longer-term rates declined. The FOMC’s successive post-
recession increases in the  federal funds rate  occurred between December 2016 and  December 2017, although longer-term rates 
have not increased by a similar magnitude. The more recent increase in rates has resulted in competitive loan yields which are 
more appealing from a profitability perspective, in Management’s opinion. 

The  funding  of  the  Company’s  earning  assets  is  primarily  customer  deposits.  The  Company’s  long-term  strategy  includes 
maximizing checking and savings deposits as these types of deposits are lower-cost and less sensitive to changes in interest rates 
compared to time deposits. The 2017 average volume of checking and savings deposits was 95 percent of average total deposits. 

The Company recognized a reversal of the provision for loan losses of $1.9 million in 2017. Credit quality improved during 2017 
with  nonperforming  assets  declining  $4  million  to  $8  million  at  December  31,  2017.  The  Company’s  net  losses  in  2017  were

0.08% of average loan balances. These developments were reflected in Management’s evaluation of credit quality, the level of the 
provision for loan losses, and the adequacy of the allowance for loan losses at December 31, 2017.  

The Company presents its net interest margin and net interest income on an FTE basis using the current statutory federal tax rate. 
Management believes the  FTE basis is  valuable to the reader because the  Company’s loan and investment securities portfolios 
contain  a  relatively  large  portion  of  municipal  loans  and  securities  that  are  federally  tax  exempt.    The  Company’s  tax  exempt 
loans and securities composition may not be similar to that of other banks. Therefore in order to reflect the impact of the federally 
tax  exempt  loans  and  securities  on  the  net  interest  margin  and  net  interest  income  for  comparability  with  other  banks,  the 
Company presents its net interest margin and net interest income on an FTE basis. 

The  Company’s  significant  accounting  policies  (see  Note  1  (“Summary  of  Significant  Accounting  Policies”)  to  Financial 
Statements  in  the  Company’s  2017  Form  10-K)  are  fundamental  to  understanding  the  Company’s  results  of  operations  and 
financial  condition.  The  Company  adopted  the  FASB  ASU  2016-09,  Improvements  to  Employee  Share-Based  Payment 
Accounting effective January 1, 2017. The 2017 results reflect the Company’s prospective adoption of ASU 2016-09; The 2017 
income tax provision was $698 thousand lower than would have been under accounting standards prior to the adoption of ASU 
2016-09.

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

Comparing  2016  with  2015,  net  income  increased  $100  thousand  due  to  a  reversal  of  provision  for  loan  losses  and  lower 
noninterest expense, partially offset by lower net interest and fee income (FTE), lower noninterest income and higher income tax 
provision (FTE). The lower net interest and fee income (FTE) was primarily caused by lower average balances of loans, partially 
offset  by  higher  average  balances  of  investments  and  lower  average  balances  of  higher-costing  time  deposits.  The  Company 
recorded a reversal of the provision for loan losses of $3.2 million, reflecting Management's evaluation of losses inherent in the 
loan  portfolio.  Noninterest  income  decreased  primarily  due  to  reduced  levels  of  service  charges  on  deposit  accounts,  financial 
services commissions and other service fees, partially offset by higher debit card fees. Noninterest expense decreased mostly due 
to  lower  personnel  expense,  lower  occupancy  expense,  and  lower  other  operating  expense,  offset  in  part  by  higher  legal  fees. 
Income tax provision (FTE) increased in 2016 due to higher pretax income, declining tax preference items and lower tax credits.

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  2017  with  2016,  net  interest  and  loan  fee  income  (FTE)  decreased  $959  thousand  mostly  due  to  lower  average 
balances  of  loans  (down  $109  million)  and  lower  net  yield  on  those  loans  (down  0.16%),  partially  offset  by  higher  average 
balances of investments (up $255 million). 

Comparing 2016 with 2015, net interest and loan fee income (FTE) decreased $3.2 million due to lower average balances of loans 
(down $194 million), partially offset by higher average balances of investments (up $255 million) and lower average balances of 
higher-costing time deposits (down $62 million). 

Loan volumes have declined due to payoffs and problem loan workout activities (such as chargeoffs, collateral repossessions and 
principal payments), particularly with purchased loans, and reduced volumes of loan originations.  The Company did not take an 
aggressive  posture  relative  to  loan  portfolio  growth  during  the  post-recession  period  of  historically  low  interest  rates. 
Management increased investment securities as loan volumes declined. The average balance of the investment securities portfolio 
increased from $2.8 billion in 2015 to $3.1 billion in 2016 and $3.3 billion in 2017. The Company has been purchasing shorter-
duration investment securities with lower yields than longer-duration securities to increase liquidity. The Company’s high levels 
of liquidity will provide an opportunity to obtain higher yielding assets as market interest rates rise. 

Yields on interest-earning assets declined due to historically low interest rates prevailing in the market. The net interest margin 
(FTE)  was  3.12%  in  2017,  3.24%  in  2016  and 3.36%  in  2015. The  volume  of  older-dated  higher-yielding  loans  and  securities 
declined  due  to  principal  maturities  and  paydowns.  As  the  investment  securities  portfolio  grew  during  the  three  years  ended 
December  31,  2017,  the  investment  securities  portfolio  generated  an  increasing  portion  of  the  interest  income  (FTE).  Interest 
income (FTE) generated from investments represented 47.0% of total interest income (FTE) in 2015, 52.2% in 2016 and 57.0% in 
2017. During the three years ended December 31, 2017, the net interest margin (FTE) was affected by low market interest rates 
and the changing composition of interest-earning assets. 

The Company has been replacing higher-cost funding sources with low-cost deposits and interest expense has declined to offset 
some of the decline in interest income. Interest expense has been reduced by lowering rates paid on interest-bearing deposits and 
borrowings by reducing the volume of higher-cost funding sources. Federal Home Loan Bank (“FHLB”) advances were repaid in 
January 2015. Average balances of time deposits declined $27 million in 2017 compared with 2016 while lower-cost checking 
and savings deposits grew 4% in the same period. Lower-cost checking and savings deposits accounted for 94.8% of total average 
deposits in 2017 compared with 94.1% in 2016 and 92.5% in 2015.

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 2015, 2016 and 2017. Due to the 
Tax Cuts and Jobs  Act of 2017, the federal tax rate  will be 21 percent for 2018; as such, the upward adjustment  to reflect the 
effect of income exempt from federal taxation will be lower in 2018.

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

Provision for Loan Losses 

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

The Company recorded a reversal of the provision for loan losses of $1.9 million in 2017 and $3.2 million in 2016. The Company 
provided no provision for loan losses in 2015.  Classified loans declined $10.5 million (which included nonperforming loans of 
$5.9 million) in 2017. The Company’s net loan losses decreased from $1.7 million in 2015 to $617 thousand in 2016 and $1.0 
million in 2017; these developments were reflected in Management’s evaluation of credit quality, the level of the provision for 
loan losses, and the adequacy of the allowance for loan losses at December 31, 2017. At December 31, 2017, the Company had 
$7.8 million in residential real estate secured loans which are indemnified from loss by the FDIC up to eighty percent of principal; 
the indemnification expires February 6, 2019. For further information regarding credit risk, the FDIC loss-sharing agreements, net 
credit losses and the allowance for loan losses, see the “Loan Portfolio Credit Risk” and “Allowance for Loan Losses” sections of 
this Report.

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  2016,  noninterest  income  decreased  $1.3  million  or  2.7%  compared  with  2015.  Service  charges  on  deposits  decreased  $1.4 
million  due  to  declines  in  fees  charged  on  overdrawn  and  insufficient  funds  accounts  (down  $1.1  million)  and  lower  fees  on 
analyzed accounts (down $393 thousand). The decrease  was partially offset by increased debit card fees of $206 thousand as a 
result of increased transaction volumes.

In 2017, noninterest expense increased $1.5 million compared with 2016. The 2017 noninterest expense included a $5.5 million 
loss contingency and a $625 thousand impairment of low income housing limited partnership investments due to enactment of the 
Tax  Cuts  and  Jobs  Act  of  2017.  The  loss  contingency  represents  the  Company’s  estimated  refunds  to  customers  of  revenue 
recognized  in  prior  years.  Outsourced  data  processing  services  expense  increased  $530  thousand  primarily  due  to  additional 
processing  services.  Expenses  for  occupancy  and  equipment  increased  $413  thousand  due  to  technology  upgrades.  Other 
noninterest  expense  decreased  $3.1  million  primarily  due  to  decreases  in  correspondent  bank  service  charges  and  insurance 
premiums. Professional fees decreased $1.8 million due to lower legal fees associated with nonperforming assets. Amortization of 
intangibles decreased $427 thousand as assets are amortized on a declining balance method. 

In 2016, noninterest expense decreased $3.5 million or 3.4% compared with 2015. Salaries and related benefits decreased $685 
thousand  primarily  due  to  employee  attrition,  offset  in  part  by  higher  expenses  for  stock  based  compensation.  Occupancy  and

equipment expense decreased $377 thousand in 2016 compared with 2015 mostly due to branch closures and a lease expiration 
related  to  a  non-branch  building,  partially  offset  by  higher  depreciation  costs  for  technology.  Courier  expense  decreased  $377 
thousand  primarily  due  to  logistical  changes  and  switching  to  new  vendors.  Amortization  of  identifiable  intangibles  decreased 
$352 thousand as assets are amortized on a declining balance method. Other operating expense decreased $3.3 million primarily 
due to lower expenses for correspondent service charges, insurance premiums, operating losses on limited partnership investments 
and higher net  gains on  foreclosed properties. Professional fees increased $1.5  million due to higher legal  fees associated  with 
loan administration and collection activities.  

Provision for Income Tax 

The income tax provision (FTE) was $49.3 million in 2017 compared with $34.2 million in 2016 and $32.1 million in 2015. The 
2017 income tax provision (FTE) included  a $12.3 million charge to re-measure the Company’s net deferred tax asset triggered 
by enactment of the Tax Cuts and Jobs Act of 2017. Effective January 1, 2017, the Company adopted ASU 2016-09 which has the 
potential to create volatility in the book tax provision at the time nonqualified stock options are exercised or expire. During 2017, 
509 thousand shares were issued due to the exercise of nonqualified stock options resulting in a tax deduction exceeding related 
share  based  compensation  by  $1.7  million.  The  2017  income  tax  provision  was  $698  thousand  lower  than  it  would  have  been 
under accounting standards prior to the adoption of ASU 2016-09. The 2017 effective tax rate (FTE) was 49.6% compared with 
36.8% in 2016 and 35.3% in 2015. The effective tax rates without FTE adjustments were  42.6% for 2017, 26.4% for 2016 and 
23.4% for 2015. The effective tax rates for 2017 were higher than the effective tax rates for 2016 due to the 2017 $12.3 million 
charge  to  re-measure  the  Company’s  net  deferred  tax  asset,  higher  pre-tax  income,  and  declining  tax  preference  items.  The 
effective  tax  rates  for  2016  were  higher  than  the  effective  tax  rates  for  2015  due  to  higher  pre-tax  income  and  declining  tax 
preference items. Interest income earned on municipal securities and loans which are exempt from federal income taxes  and the 
tax credits earned from investments in limited partnerships have each declined in 2017 and 2016.  

Investment Securities Portfolio 

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

Management  has  increased  the  investment  securities  portfolio  in  response  to  deposit  growth  and  loan  volume  declines.  The 
carrying value of the Company’s investment securities portfolio was $3.4 billion as of December 31, 2017 and $3.2 billion as of 
December 31, 2016. 

Management  continually  evaluates  the  Company’s  investment  securities  portfolio  in  response  to  established  asset/liability 
management objectives, changing market conditions that could affect profitability, liquidity, and the level of interest rate risk to 
which the Company is exposed.  These evaluations may cause Management to change the level of funds the Company deploys 
into  investment  securities  and  change  the  composition  of  the  Company’s  investment  securities  portfolio.  In  2016  Management 
reduced  securities  of  U.S.  Government  sponsored  entities  to  reduce  call  optionality  and  increased  agency  residential  MBS  to 
develop more reliable cash flows. In 2017 corporate securities increased in order to improve yields without extending the duration 
of the bond portfolio. 

As of December 31, 2017, substantially all of the Company’s investment securities continue to be investment grade rated by one 
or  more  major  rating  agencies.  In  addition  to  monitoring  credit  rating  agency  evaluations,  Management  performs  its  own 
evaluations  regarding  the  credit  worthiness  of  the  issuer  or  the  securitized  assets  underlying  asset-backed  securities.  The 
Company’s procedures for evaluating investments in securities are in accordance with guidance issued by the Board of Governors 
of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating Agencies” 
(SR 12-15) and other regulatory guidance. There have been no significant differences in our internal analyses compared with the 
ratings assigned by the third party credit rating agencies.

During  the  third  quarter  2017,  the  Atlantic  hurricane  season  caused  severe  damage  within  many  US  States  and  Territories.  
Management  has  evaluated  investment  security  exposures  within  the  counties  receiving  disaster  designations.  The  Company’s 
exposures  are  limited  to  municipal  and  corporate  bond  investment  securities  from  issuers  within  Texas,  Florida  and  Georgia 
counties.  The  Company  holds  municipal  bonds  of  $19  million  issued  by  17  municipalities  within  Texas  counties,  $8  million 
issued by eight municipalities within Florida counties and $6 million issued by four municipalities within Georgia counties. The

In  Management’s  judgment,  each  municipality’s  financial  resources  and  the  availability  of  federal  and  state  disaster  funds 
mitigate the risk exposure of the bonds, particularly for intermediate-term and longer-term bonds.  

In addition, the Company holds one $12.0 million (market value) corporate bond maturing in 2021 issued by a regulated utility in 
a Texas county which can recapture capital expenditures through rates charged customers; the market value of this corporate bond 
at December 31, 2017 was 119.0% of its par value, which reflects the bond’s 9.15% coupon rate. 

Based on currently available information, Management does not expect any of the  bonds affected by the  hurricanes  to become 
impaired; Management will continue to monitor the value of these bonds for impairment. 

The following tables summarize the total general obligation and revenue bonds issued by states and political subdivisions held in 
the  Company’s investment  securities portfolios as of the dates indicated, identifying the state  in  which  the issuing government 
municipality or agency operates.    

At  December  31,  2017,  the  Company’s  investment  securities  portfolios  included  securities  issued  by  647  state  and  local 
government municipalities and agencies located within 44 states.  None of the Company’s investment securities were issued by 
Puerto  Rican  government  entities.  The  largest  exposure  to  any  one  municipality  or  agency  was  $10.0  million  (fair  value) 
represented by nine general obligation bonds.

See Note 2 to the consolidated financial statements for additional information related to the investment securities. 

Loan Portfolio 

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

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

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

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

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

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

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

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

For  management  purposes,  the  Company  segregates  its  loan  portfolio  into  two  segments.  Loans  originated  by  the  Company 
following its loan underwriting policies and procedures are separated from loans purchased from the FDIC. Loan volumes have 
declined  due  to  payoffs  and  problem  loan  workout  activities,  particularly  with  purchased  loans,  and  reduced  volumes  of  loan

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 2016 and  2017 due to payoffs, chargeoffs and sale of Other Real Estate Owned. At 
December  31, 2017,  one  loan  secured  by  commercial  real  estate  with  a  balance  of  $4.3 million  was  on  nonaccrual  status.  The 
remaining  five  nonaccrual  loans  held  at  December  31,  2017  had  an  average  carrying  value  of  $328  thousand  and  the  largest 
carrying value was $1.0 million. 

Management believes the overall credit quality of the loan portfolio is reasonably stable; however, classified and nonperforming 
assets could fluctuate from period to period. The performance of any individual loan can be affected by external factors such as 
the interest rate environment, economic conditions, and collateral values or factors particular to the borrower. No assurance can 
be given that additional increases in nonaccrual and delinquent loans will not occur in the future.

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, 2017 is economic and business conditions $0.5 million. Also 
included in the unallocated allowance is the risk of losses attributable to general attributes of the Company's loan portfolio and 
credit administration (internal factors). The internal factors evaluated by the Company and the judgmental amount of unallocated 
reserve assigned by Management are: loan review system $1.1 million, adequacy of lending Management and staff $0.5 million 
and concentrations of credit $1.3 million.

The 2017 decline in the allowance for loan losses was due to declines in classified loans, delinquent loans, and the overall loan 
portfolio. The increase in the allocation of the allowance for loan losses to commercial real estate and construction loans is due to 
increased loan volumes outstanding. The decline in the unallocated portion was due to improved economic conditions within the 
Company’s geographic markets.

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.  Assets and liabilities may mature or re-price at different times. Assets and liabilities may 
re-price  at  the  same  time  but  by  different  amounts.  Short-term  and  long-term  market  interest  rates  may  change  by  different 
amounts. The timing and amount of cash flows of various assets or liabilities may shorten or lengthen as interest rates change. In 
addition, the changing levels of interest rates may have an impact on loan demand, demand for various deposit products, credit 
losses,  and  other  elements  of  earnings  such  as  account  analysis  fees  on  commercial  deposit  accounts  and  correspondent  bank 
service charges. 

The Company’s earnings are affected not only by general economic conditions, but also by the monetary and fiscal policies of the 
United  States  government  and  its  agencies,  particularly  the  Federal  Open  Market  Committee  (the  “FOMC”).    The  monetary 
policies of the FOMC can influence the overall growth of loans, investment securities, and deposits and the level of interest rates 
earned  on  assets  and  paid  for  liabilities.    The  nature  and  impact  of  future  changes  in  monetary  policies  are  generally  not 
predictable. 

Management expects a high level of uncertainty in regard to interest rate levels in the immediate term, and Management’s most 
likely earnings forecast for the twelve months ending December 31, 2018 assumes market interest rates will gradually rise, with 
short-term rates rising more than long-term rates. 

In  adjusting  the  Company's  asset/liability  position,  Management  attempts  to  manage  interest  rate  risk  while  enhancing  the  net 
interest  margin  and  net  interest  income.  At  times,  depending  on  expected  increases  or  decreases  in  general  interest  rates,  the 
relationship between long and short-term interest rates, market conditions and competitive factors, Management may adjust the 
Company's interest rate risk position in order to manage its net interest margin and net interest income. The Company's results of 
operations and net portfolio values remain subject to changes in interest rates and to fluctuations in the difference between long 
and short-term interest rates. 

The Company’s asset and liability position  was  slightly  “asset sensitive” at  December 31, 2017, depending on the  interest rate 
assumptions applied to the simulation model employed by Management to measure interest rate risk. An “asset sensitive” position 
results in a slightly larger change in interest income than in interest expense resulting from application of assumed interest rate 
changes. Simulation estimates depend on, and will change with, the size and mix of the actual and projected balance sheet at the 
time of each simulation. Management continues to monitor the interest rate environment as well as economic conditions and other 
factors it deems relevant in managing the Company's exposure to interest rate risk. 

The  Company  does  not  currently  engage  in  trading  activities  or  use  derivative  instruments  to  control  interest  rate  risk,  even 
though such activities may be permitted with the approval of the Company's Board of Directors. 

Market Risk - Equity Markets 

Equity  price  risk  can  affect  the  Company.  As  an  example,  any  preferred  or  common  stock  holdings,  as  permitted  by  banking 
regulations, can fluctuate in value. Management regularly assesses the extent and duration of any declines in market value, the 
causes of such declines, the  likelihood of a recovery in  market value, and its intent to  hold securities  until a recovery in  value 
occurs.  Declines  in  value  of  preferred  or  common  stock  holdings  that  are  deemed  “other  than  temporary”  could  result  in  loss 
recognition in the Company's income statement. 

Fluctuations  in  the  Company's  common  stock  price  can  impact  the  Company's  financial  results  in  several  ways.  First,  the 
Company has regularly repurchased and retired its common stock; the market price paid to retire the Company's common stock 
affects the level of the Company's shareholders' equity, cash flows and shares outstanding. Second, the Company's common stock 
price  impacts  the  number  of  dilutive  equivalent  shares  used  to  compute  diluted  earnings  per  share.  Third,  fluctuations  in  the 
Company's  common  stock  price  can  motivate  holders  of  options  to  purchase  Company  common  stock  through  the  exercise  of 
such  options  thereby  increasing  the  number  of  shares  outstanding  and  potentially  adding  volatility  to  the  book  tax  provision.

Finally,  the  amount  of  compensation  expense  associated  with  share  based  compensation  fluctuates  with  changes  in  and  the 
volatility of the Company's common stock price. 

Market Risk - Other  

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

Liquidity and Funding 

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

In  recent  years,  the  Company's  deposit  base  has  provided  the  majority  of  the  Company's  funding  requirements.  This  relatively 
stable and low-cost  source of funds, along  with shareholders' equity, provided 98 percent of funding for average  total assets in 
2017 and in 2016. The stability of the Company’s funding from customer deposits is in part reliant on the confidence clients have 
in the Company. The Company places a very high priority in maintaining this confidence through conservative credit and capital 
management practices and by maintaining an appropriate level of liquidity reserves. 

Liquidity is further provided by assets such as balances held at the Federal Reserve Bank, investment securities, and amortizing 
loans. The Company's investment securities portfolio provides a substantial secondary liquidity reserve. The Company held $3.4 
billion  in  total  investment  securities  at  December  31,  2017.  Under  certain  deposit,  borrowing  and  other  arrangements,  the 
Company must hold and pledge investment securities as collateral. At  December 31, 2017, such collateral requirements totaled 
approximately $716 million. 

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

Management  continually  monitors  the  Company’s  cash  levels.  Loan  demand  from  credit  worthy  borrowers  will  be  dictated  by 
economic  and  competitive  conditions.  The  Company  aggressively  solicits  non-interest  bearing  demand  deposits  and  money 
market checking deposits, which are the least sensitive to changes in interest rates. The growth of these deposit balances is subject 
to heightened competition, the success of the Company's sales efforts, delivery of superior customer service, new regulations and 
market conditions. The Company does not aggressively solicit higher-costing time deposits; as a result, Management anticipates 
such deposits will decline. Changes in interest rates, most notably rising interest rates, could impact deposit volumes. Depending 
on economic conditions, interest rate levels, liquidity management and a variety of other conditions, deposit growth may be used 
to  fund  loans  or  purchase  investment  securities.  However,  due  to  possible  volatility  in  economic  conditions,  competition  and 
political uncertainty, loan demand and levels of customer deposits are not certain. Shareholder dividends are expected to continue 
subject to the Board's discretion and continuing evaluation of capital levels, earnings, asset quality and other factors. 

Westamerica Bancorporation ("Parent Company") is a separate entity apart from Westamerica Bank (“Bank”) and must provide 
for  its  own  liquidity.  In  addition  to  its  operating  expenses,  the  Parent  Company  is  responsible  for  the  payment  of  dividends 
declared  for  its  shareholders,  and  interest  and  principal  on  any  outstanding  debt.  The  Parent  Company  currently  has  no  debt. 
Substantially all of the Parent Company's revenues are obtained from subsidiary dividends and service fees.

The  Bank’s  dividends  paid  to  the  Parent  Company,  proceeds  from  the  exercise  of  stock  options,  and  Parent  Company  cash 
balances  provided  adequate  cash  for  the  Parent  Company  to  pay  shareholder  dividends  of  $41  million  in  2017,  $40 million  in 
2016 and $39 million in 2015, and retire common stock in the amount of $314  thousand in 2017, $6 million  in 2016 and $15 
million  in  2015.  Payment  of  dividends  to  the  Parent  Company  by  the  Bank  is  limited  under  California  and  Federal  laws.  The 
Company  believes  these  regulatory  dividend  restrictions  will  not  have  an  impact  on  the  Parent  Company's  ability  to  meet  its 
ongoing cash obligations.

Operating  lease  obligations  have  not  been  reduced  by  minimum  sublease  rentals  of  $2  million  due  in  the  future  under 
noncancelable subleases. Operating lease obligations may be retired prior to the contractual maturity as discussed in the notes to 
the  consolidated  financial  statements.  The  purchase  obligation  consists  of  the  Company’s  minimum  liabilities  under  contracts 
with third-party automation services providers. 

Capital Resources 

The Company has historically generated high levels of earnings, which provide a means of accumulating capital. The Company's 
net income as a percentage of average shareholders' equity (“return on equity” or “ROE”) has been 8.4% in 2017, 10.9% in 2016 
and 11.3% in 2015. The Company also raises capital as employees exercise stock options. Capital raised through the exercise of 
stock options was $25 million in 2017, $24 million in 2016 and $5 million in 2015. 

The Company paid common dividends totaling $41 million in 2017, $40 million in 2016 and $39 million in 2015, which represent 
dividends  per  common  share  of  $1.57,  $1.56  and  $1.53,  respectively.  The  Company's  earnings  have  historically  exceeded 
dividends paid to shareholders. The amount of earnings in excess of dividends provides the Company resources to finance growth 
and  maintain  appropriate  levels  of  shareholders'  equity.  In  the  absence  of  profitable  growth  opportunities,  the  Company  has 
repurchased  and  retired  its  common  stock  as  another  means  to  return  earnings  to  shareholders. The  Company  repurchased  and 
retired 6 thousand shares valued at $314 thousand in 2017, 137 thousand shares valued at $6 million in 2016 and 344 thousand 
shares valued at $15 million in 2015. 

The Company's primary capital resource is shareholders' equity, which was $590 million at December 31, 2017 compared with 
$561 million at December 31, 2016. The Company's ratio of equity to total assets was 10.71% at December 31, 2017 and 10.46% 
at December 31, 2016. 

The Company performs capital stress tests on a periodic basis to evaluate the sustainability of its capital. Under the stress testing, 
the  Company  assumes  various  scenarios  such  as  deteriorating  economic  and  operating  conditions,  unanticipated  asset 
devaluations, and significant operational lapses. The Company measures the impact of these scenarios on its earnings and capital. 
Based  on  the  results  of  the  most  recent  stress  tests,  Management  is  satisfied  with  the  capital  condition  of  the  Bank  and  the 
Company.  However,  no  assurance  can  be  given  the  Bank  or  Company  will  not  experience  a  period  of  reduced  earnings  or  a 
reduction in capital from unanticipated events and circumstances.

Capital to Risk-Adjusted Assets 

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

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

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

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

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

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

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

The Company and the Bank routinely project capital levels by analyzing forecasted earnings, credit quality, securities valuations, 
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.

(1) The rates for total deposits reflect value of noninterest-bearing deposits. 

The  Company’s  strategy  includes  building  the  value  of  its  deposit  base  by  building  balances  of  lower-costing  deposits  and 
avoiding reliance on higher-costing time deposits. From 2015 to 2017 higher costing time deposits declined from 7% to 5% of 
total deposits. The Company’s average balances of checking and savings accounts represented 95% of average balances of total 
deposits in 2017 compared with 94% in 2016 and 93% in 2015. 

Total time deposits were $232 million and $256 million at December 31, 2017 and 2016, respectively.  The following table sets 
forth, by time remaining to maturity, the Company’s total domestic time deposits. The Company has no foreign time deposits.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

The  Company  does  not  currently  engage  in  trading  activities  or  use  derivative  instruments  to  control  interest  rate  risk,  even 
though such activities may be permitted with the approval of the Company’s Board of Directors. 

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

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, 2017. Internal control over financial reporting is a process designed to provide reasonable 
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in 
accordance  with  generally  accepted  accounting  principles.  The  Company’s  system  of  internal  control  over  financial  reporting 
includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly 
reflect  the  transactions  and  dispositions  of  the  assets  of  the  Company;  (ii)  provide  reasonable  assurance  that  transactions  are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, 
and that receipts and expenditures of the Company are being made only in accordance with authorizations of Management and 
Directors  of  the  Company;  and  (iii)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized 
acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements. 

Management  performed  an  assessment  of  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of 
December  31,  2017  based  upon  criteria  in  Internal  Control  —  Integrated  Framework  (2013)  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, Management determined that the 
Company’s  internal  control  over  financial  reporting  was  effective  as  of  December  31,  2017  based  on  the  criteria  in  Internal 
Control - Integrated Framework (2013) issued by COSO. 

The Company’s independent registered public accounting firm has issued an attestation report on Management’s assessment of 
the Company’s internal control over financial reporting. Their opinion and attestation on internal control over financial reporting 
appear on page 89.

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  and  judgments  about  future  economic  and  market  conditions.  These  estimates  and  judgments  may  affect 
reported amounts of assets and liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. Although the 
estimates contemplate current conditions and how Management expects them to change in the future, it is reasonably possible that 
in  2018  actual  conditions  could  be  worse  than  anticipated  in  those  estimates,  which  could  materially  affect  our  results  of 
operations and financial conditions. 

Principles of Consolidation. The consolidated financial  statements include the accounts of the Company and all the Company’s 
subsidiaries.  Significant  intercompany  transactions  have  been  eliminated  in  consolidation.  The  Company  does  not  maintain  or 
conduct transactions with any unconsolidated special purpose entities. 

Cash. Cash includes Due From Banks balances which are readily convertible to known amounts of cash and are generally 90 days 
or less from maturity at the time of initiation, presenting insignificant risk of changes in value due to interest rate changes. 

Securities. Investment securities consist of debt securities of the  U.S. Treasury, government sponsored entities, states,  counties,  
municipalities,  corporations,  agency  and  non-agency  mortgage-backed  securities,  asset-backed  securities  and  equity  securities. 
Securities transactions are recorded on a trade date basis. The Company classifies its debt and marketable equity securities in one 
of  three  categories:  trading,  available  for  sale  or  held  to  maturity.  Trading  securities  are  bought  and  held  principally  for  the 
purpose of selling them in the near term. Trading securities are recorded at fair value with unrealized gains and losses included in 
earnings. Held to maturity securities are those debt securities which the Company has the ability and intent to hold until maturity. 
Held to maturity securities are recorded at cost, adjusted for the amortization of premiums or accretion of discounts. Securities not 
included in trading or held to maturity are classified as available for sale.  Available for sale securities are recorded at fair value. 
Unrealized  gains  and  losses,  net  of  the  related  tax  effect,  on  available  for  sale  securities  are  included  in  accumulated  other 
comprehensive income. 

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

A decline in the market value of any available for sale or held to maturity security below amortized cost that is deemed other than 
temporary  results  in  a  charge  to  earnings  and  the  establishment  of  a  new  cost  basis  for  the  security.  Unrealized  investment 
securities  losses  are  evaluated  at  least  quarterly  to  determine  whether  such  declines  in  value  should  be  considered  “other  than 
temporary”  and  therefore  be  subject  to  immediate  loss  recognition  in  income.  Although  these  evaluations  involve  significant 
judgment, an unrealized loss in the fair value of a debt security is generally deemed to be temporary when the fair value of the

security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration 
in  the  financial  condition  of  the  issuer,  and  the  Company  does  not  intend  to  sell  or  be  required  to  sell  the  securities  before 
recovery of its amortized cost. An unrealized loss in the value of an equity security is generally considered temporary when the 
fair value of the security declined primarily due to current market conditions and not deterioration in the financial condition of the 
issuer, the Company expects the fair value of the security to recover in the near term and the Company does not intend to sell or 
be required to sell the securities before recovery of its cost basis. Other factors that may be considered in determining whether a 
decline in the value of either a debt or an equity security is “other than temporary” include ratings by recognized rating agencies, 
actions of commercial banks or other lenders relative to the continued extension of credit facilities to the issuer of the security, the 
financial condition, capital strength and near-term prospects of the issuer, and recommendations of investment advisors or market 
analysts. 

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

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

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

Loans. Loans are stated at the principal amount outstanding, net of unearned discount and unamortized deferred fees and costs. 
Interest  is  accrued  daily  on  the  outstanding  principal  balances.  Loans  which  are  more  than  90  days  delinquent  with  respect  to 
interest  or  principal,  unless  they  are  well  secured  and  in  the  process  of  collection,  and  other  loans  on  which  full  recovery  of 
principal or interest is in doubt, are placed on nonaccrual status. Interest previously accrued on loans placed on nonaccrual status 
is  charged  against  interest  income.  In  addition,  some  loans  secured  by  real  estate  with  temporarily  impaired  values  and 
commercial  loans  to  borrowers  experiencing  financial  difficulties  are  placed  on  nonaccrual  status  (“performing  nonaccrual 
loans”)  even  though  the  borrowers  continue  to  repay  the  loans  as  scheduled.  When  the  ability  to  fully  collect  nonaccrual  loan 
principal  is  in  doubt,  payments  received  are  applied  against  the  principal  balance  of  the  loans  on  a  cost-recovery  method  until 
such time as full collection of the remaining recorded balance is expected. Any additional interest payments received after that 
time  are  recorded  as  interest  income  on  a  cash  basis.  Performing  nonaccrual  loans  are  reinstated  to  accrual  status  when 
improvements in credit quality eliminate the doubt as to the full  collectability of both  interest and principal.  Certain consumer 
loans or auto receivables are charged off against the allowance for credit losses when they become 120 days past due.  

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

Nonrefundable fees and certain costs associated with originating or acquiring loans are deferred and amortized as an adjustment 
to  interest  income  over  the  contractual  loan  lives.  Upon  prepayment,  unamortized  loan  fees,  net  of  costs,  are  immediately 
recognized in interest income. Other fees, including those collected upon principal prepayments, are included in interest income

when received.  Loans held  for sale  are identified  upon origination and are reported at the lower of cost or  market value on an 
aggregate loan basis. 

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

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

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

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

The allowance for credit losses is established through provisions for credit losses charged to income. Losses on loans, including 
impaired loans, are charged to the allowance for loan losses when all or a portion of the recorded amount of a loan is deemed to 
be  uncollectible.  Recoveries  of  loans  previously  charged  off  are  credited  to  the  allowance  when  realized.  The  Company’s 
allowance for credit losses is  maintained at a level considered adequate  to provide  for losses that can be  estimated based upon 
specific and general conditions. These include conditions unique to individual borrowers, as well as overall credit loss experience, 
the  amount  of  past  due,  nonperforming  and  classified  loans,  recommendations  of  regulatory  authorities,  prevailing  economic 
conditions, FDIC loss-sharing or similar credit protection agreements and other factors. A portion of the allowance is specifically 
allocated to impaired loans whose full collectability is uncertain. Such allocations are determined by Management based on loan-
by-loan analyses. The Company evaluates all classified loans and nonaccrual loans with outstanding principal balances in excess 
of $500 thousand, and all “troubled debt restructured” loans for impairment.  A second allocation is based in part on quantitative 
analyses of historical credit loss experience. The results of this analysis are applied to current loan balances to allocate the reserve 
to the respective segments of the loan portfolio exclusive of loans individually evaluated for impairment. In addition, consumer

installment  loans  which  have  similar characteristics  and are  not  usually criticized  using  regulatory  guidelines are analyzed  and 
reserves established  based on the historical loss rates and delinquency trends, grouped by the number of days the payments on 
these loans are delinquent. The remainder of the reserve is considered to be unallocated. The unallocated allowance is established 
to  provide  for  probable  losses  that  have  been  incurred  as  of  the  reporting  date  but  not  reflected  in  the  allocated  allowance.  It 
addresses additional qualitative factors consistent with Management’s analysis of the level of risks inherent in the loan portfolio, 
which are related to the risks of the Company’s general lending activity. Included in the unallocated allowance is the risk of losses 
that are attributable to national or local economic or industry trends which have occurred but have not yet been recognized in past 
loan  charge-off  history  (external  factors).  The  external  factors  evaluated  by  the  Company  include:  economic  and  business 
conditions, external competitive issues, and other factors. Also included in the unallocated allowance is the risk of losses  that are 
attributable to general attributes of the Company’s loan portfolio and credit administration (internal factors). The internal factors 
evaluated by the Company include: loan review system, adequacy of lending Management and staff, loan policies and procedures, 
problem  loan  trends,  concentrations  of  credit,  and  other  factors.  By  their  nature,  these  risks  are  not  readily  allocable  to  any 
specific segment of the loan portfolio in a statistically meaningful manner. 

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

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

Covered Other Real Estate  Owned.  Other real estate owned covered under loss-sharing agreements  with the  FDIC is reported 
exclusive of expected reimbursement cash flows from the FDIC. Upon transferring covered loan collateral to covered other real 
estate owned status, the covered loan collateral is recorded at fair value, generally based upon an independent property appraisal, 
less estimated disposition costs with losses charged against acquisition date fair value discounts; the amount of losses exceeding 
acquisition date fair value discounts are recognized as noninterest expense inclusive of expected reimbursement cash flows from 
the FDIC.  Subsequent losses incurred due to any decline in annual independent property appraisal valuations are recognized as 
noninterest expense inclusive of expected reimbursement cash flows from the FDIC. 

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

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

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

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

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 2017, the Company adopted the following new accounting guidance: 

FASB Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting, was issued 
March 30, 2016. The provisions of the new standard changed several aspects of the accounting for share-based payment award 
transactions,  including:  (1)  Accounting  and  Cash  Flow  Classification  for  Excess  Tax  Benefits,  (2)  Forfeitures,  and  (3)  Tax 
Withholding Requirements and Cash Flow Classification. The Company adopted the ASU provisions effective January 1, 2017, 
which has the potential to create volatility in the book tax provision at the time nonqualified stock options are exercised or expire. 
During  2017,  509  thousand  shares  were  issued  due  to  the  exercise  of  nonqualified  stock  options  resulting  in  a  tax  deduction 
exceeding related share based compensation by $1,667 thousand. The 2017 income tax provision was $698 thousand lower than it 
would  have  been  under  accounting  standards  prior  to  the  adoption  of  ASU  2016-09.  The  Company  elected  to  account  for 
forfeitures as they occur. 

Recently Issued Accounting Standards 

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

Approximately 73% of our revenue, including all of our net interest income and a portion of our noninterest income,  is out of 
scope of the guidance. The contracts that are in scope of the guidance are primarily related to service charges and fees on deposit 
accounts, merchant processing fees, trust fees and other service charges, commissions and fees. We have completed analyzing the

individual contracts in scope and determined our revenue recognition will not change in any material regard upon adoption of the 
ASU. The Company adopted the ASU on January 1, 2018. 

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

The  Company  was  required  to  adopt  the  ASU  provisions  on  January  1,  2018,  and  for  those  equity  securities  with  readily 
determinable  fair  values,  the  Company  elected  the  retrospective  transition  approach  with  a  cumulative  effect  adjustment  to  the 
balance  sheet  and  for  those  equity  securities  that  do  not  have  readily  determinable  fair  values,  the  Company  elected  the 
prospective transition approach. The impact of the adoption of this accounting standard on the Company’s consolidated financial 
statements  will  be  subject  to  the  price  volatility  of  the  equity  investments,  which  is  immaterial.  At  December  31,  2017,  the 
Company had $2000 thousand in equity investments with readily determinable fair value. 

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

The  Company  will  be  required  to  adopt  the  ASU  provisions  January  1,  2019,  and  plans  to  elect  the  modified  retrospective 
transition approach. Management is evaluating the impact that the ASU will have on the Company’s financial statements. As of 
December  31,  2017,  the  Company  leased  58  of  its  operating  facilities;  the  remaining  minimum  lease  payments  were  $17.5 
million. The Company does not expect a material change in noninterest expenses upon adoption of the new standard. 

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

The Company will be required to adopt the ASU provisions on January 1, 2020. Management is evaluating the impact that the 
ASU will have on the Company’s consolidated financial statements. The ultimate adjustment to the allowance for loan losses will 
be accomplished through an offsetting after-tax adjustment to shareholders’ equity. Economic conditions and the composition of 
the Company’s loan portfolio at the time of adoption will influence the extent of the adopting accounting adjustment. 

FASB  ASU  2017-08,  Receivables  –  Non-Refundable  Fees  and  Other  Costs  (Subtopic  310-20):  Premium  Amortization  on 
Purchased Callable Debt Securities, was issued March 2017. The ASU will shorten the amortization period for certain callable 
debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The 
amendments  do  not  require  an  accounting  change  for  securities  held  at  a  discount;  the  discount  continues  to  be  amortized  to 
maturity. 

The Company will be required to adopt the ASU provisions on January 1, 2019.  Management is evaluating the impact the ASU 
will have on the Company’s financial statements. 

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

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

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, 2017 and December 31, 2016, the Company 
had no high-risk collateralized mortgage obligations as defined by regulatory guidelines.

The unrealized losses on the Company’s investment securities were caused by market conditions for these types of investments, 
particularly  changes  in  risk-free  interest  rates.  The  Company  evaluates  securities  on  a  quarterly  basis  including  changes  in 
security ratings issued by rating agencies, changes in the financial condition of the issuer, and, for mortgage-backed and asset-
backed  securities,  delinquency  and  loss  information  with  respect  to  the  underlying  collateral,  changes  in  the  levels  of 
subordination  for  the  Company’s  particular  position  within  the  repayment  structure  and  remaining  credit  enhancement  as 
compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a 
major  rating  agency.  In  addition  to  monitoring  credit  rating  agency  evaluations,  Management  performs  its  own  evaluations 
regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities. 

The Company does not intend to sell any investments and has concluded that it is more likely than not that it will not be required 
to sell the investments prior to recovery of the amortized cost basis. Therefore, the Company does not consider these investments 
to be other-than-temporarily impaired as of December 31, 2017. 

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

As  of  December  31,  2017,  $715,774  thousand  of  investment  securities  were  pledged  to  secure  public  deposits  and  short-term 
borrowed funds. As of December 31, 2016,  $768,845 thousand of investment securities were pledged to secure public deposits 
and short-term borrowed funds.

The  Bank’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 Bank maintains a Loan Review Department which reports 
directly to Audit Committee of the Board of Directors. The Loan Review Department performs independent evaluations of loans 
and validates management assigned credit risk grades on evaluated loans using grading standards employed by bank regulatory 
agencies. Loans judged to carry lower-risk attributes are assigned a “pass” grade, with a minimal likelihood of loss. Loans judged 
to carry higher-risk attributes are referred to as “classified loans,” and are further disaggregated, with increasing expectations for 
loss recognition, as “substandard,” “doubtful,” and “loss.” Loan Review Department evaluations occur every calendar quarter.  If 
the Bank becomes aware of deterioration in a borrower’s performance or financial condition between Loan Review Department 
examinations, assigned risk  grades are re-evaluated promptly. Credit risk grades assigned by  management and validated by  the 
Loan Review Department are subject to review by the Bank’s regulatory authorities during regulatory examinations.

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, 2017, 2016 and 2015 no such adjustments were recorded.

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 following table summarizes information about stock options granted under the Plan as of December 31, 2017. The intrinsic 
value is calculated as the difference between the market value as of December 31, 2017 and the exercise price of the shares. The 
market value as of December 31, 2017 was $59.55 as reported by the NASDAQ Global Select Market:

The  Company  applies  the  Roll-Geske  option  pricing  model  (Modified  Roll)  to  determine  grant  date  fair  value  of  stock  option 
grants. This  model modifies the Black-Scholes Model to take  into account dividends and American options. During the  twelve 
months ended December 31,  2017, 2016 and 2015, the  Company  granted 266  thousand, 325  thousand and 343  thousand stock 
options, respectively. The following weighted average assumptions were used in the option pricing to value stock options granted 
in the periods indicated:    

Expected volatility (1)
Expected life in years (2)
Risk-free interest rate (3)
Expected dividend yield

(3) The risk-free rate over the expected life based on the US Treasury yield curve in effect at the time of the grant. 

Employee  stock  option  grants  are  being  expensed  by  the  Company  over  the  grants’  three  year  vesting  period.  The  Company 
issues new shares upon the exercise of options. The number of shares authorized to be issued for options at December 31, 2017 is 
930 thousand.

was $1,493 thousand, $1,269 thousand and $1,321 thousand, respectively. The Company adopted the ASU provisions effective 
January 1, 2017, which has the potential to create volatility in the book tax provision at the time nonqualified stock options are 
exercised or expire. During the twelve months of 2017, 509 thousand shares were issued due to the exercise of nonqualified stock 
options  resulting  in  a  tax  deduction  exceeding  related  share  based  compensation  by  $1,667  thousand.  The  2017  income  tax 
provision was $698 thousand lower than would have been under accounting standards prior to the adoption of ASU 2016-09. The 
increase  in  tax  benefits  recognized  for  the  tax  deductions  from  the  exercise  of  options  totaled  $394  thousand  for  the  twelve 
months ended December 31, 2016.  The  decrease in tax benefits recognized for the tax  deductions  from the exercise  of options 
totaled $1,284 thousand for the twelve months ended December 31, 2015. 

A summary of the status of the Company’s restricted performance shares as of December 31, 2017 and 2016 and changes during 
the twelve months ended on those dates, follows:

As of December 31, 2017 and 2016, the restricted performance shares had a weighted-average contractual life of 1.2 years and 1.1 
years,  respectively.  The  compensation  cost  that  was  charged  against  income  for  the  Company’s  restricted  performance  shares 
granted  was  $827  thousand,  $1,228  thousand  and  $535  thousand  for  the  twelve  months  ended  December  31,  2017,  2016  and 
2015,  respectively.  There  were  no  stock  appreciation  rights  or  incentive  stock  options  granted  in  the  twelve  months  ended 
December 31, 2017 and 2016. 

On February 13, 2009, the Company issued a warrant to purchase 246,640 shares of the Company’s common stock at an exercise 
price of $50.92 per share. The warrants may be exercised in a manner wherein the Company withholds shares of common stock 
issuable upon exercise of the warrant equal in value to the aggregate exercise price, in which case the warrant holder would not 
deliver cash for the aggregate exercise price and the Company would issue a number of shares equal to the intrinsic value on  the 
exercise date. The warrants remain outstanding at December 31, 2017. 

The  Company  repurchases  and  retires  its  common  stock  in  accordance  with  Board  of  Directors  approved  share  repurchase 
programs. At December 31, 2017, approximately 1,750 thousand shares remained available to repurchase under such plans. 

Shareholders have authorized two additional classes of stock of one million shares each, to be denominated “Class B Common 
Stock”  and  “Preferred  Stock,”  respectively,  in  addition  to  the  150  million  shares  of  common  stock  presently  authorized.  At 
December 31, 2017, no shares of Class B Common Stock or Preferred Stock were outstanding. 

Note 9: Regulatory Capital  

Banks  and  bank  holding  companies  are  subject  to  regulatory  capital  requirements  administered  by  federal  banking  agencies. 
Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations, involve quantitative  measures of 
assets,  liabilities,  and  certain  off-balance-sheet  items  calculated  under  regulatory  accounting  practices.  Capital  amounts  and 
classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory 
action.  The  final  rules  implementing  Basel  Committee  on  Banking  Supervision’s  capital  guidelines  for  U.S.  banks  (Basel  III 
rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in 
over a multi-year schedule, and fully phased in by January 1, 2019. Under the Basel III  rules, the Company must hold a capital 
conservation buffer above the adequately capitalized risk-based capital ratios. The capital conservation buffer is being phased in 
from  0.0%  for  2015  to  2.50%  by  2019.  The  capital  conservation  buffer  for  2017  was  1.25%  and  0.625%  for  2016.  The  net 
unrealized gain or loss on available for sale securities is not included in computing regulatory capital. Management believes as of 
December 31, 2017, the Company and Bank met all capital adequacy requirements to which they are subject. 

Prompt  corrective  action  regulations  provide  five  classifications:  well  capitalized,  adequately  capitalized,  undercapitalized, 
significantly  undercapitalized,  and  critically  undercapitalized,  although  these  terms  are  not  used  to  represent  overall  financial 
condition.  If  adequately  capitalized,  regulatory  approval  is  required  to  accept  brokered  deposits.  If  undercapitalized,  capital 
distributions are limited, as is asset growth and expansion, and capital restoration plans are required. At year-end 2017 and 2016, 
the  most  recent  regulatory  notifications  categorized  the  Bank  as  well  capitalized  under  the  regulatory  framework  for  prompt

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
Accrued liabilities

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. At December 31, 2017, the Company had no net operating loss and 
a $1,752 thousand AMT tax credit carryforward that under the Tax Cuts and Jobs Act of 2017 are fully refundable by 2022. 

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  deductibility  of  these  tax  positions  will  be  determined  through  examination  by  the  appropriate  tax  jurisdictions  or  the 
expiration of the tax statute of limitations. The Company does not anticipate any significant increase or decrease in unrecognized

thousand  and  $57  thousand,  respectively.  If  recognized,  the  entire  amount  of  the  unrecognized  tax  benefits  would  affect  the 
effective tax rate. 

The Company classifies interest and penalties as a component of the provision for income taxes.  At December 31, 2017, the tax 
years ended December 31, 2016, 2015 and 2014 remain subject to examination by the Internal Revenue Service and the tax years 
ended  December  31,  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. Available for sale investment securities are recorded at fair value on a recurring basis. Additionally, from time 
to time, the Company may be required to record at fair value other assets on a nonrecurring basis, such as other real estate owned, 
impaired loans, certain loans held for investment, investment securities held to maturity, and other assets.  These nonrecurring fair 
value adjustments typically involve the lower-of-cost or fair-value accounting of individual assets. 

In accordance with the Fair Value Measurement and Disclosure topic of the Codification, the Company bases its fair values on the 
price that would be received to sell an asset or paid to transfer a liability in the principal market or most advantageous market for 
an  asset  or  liability  in  an  orderly  transaction  between  market  participants  on  the  measurement  date  under  current  market 
conditions.  A  fair  value  measurement  reflects  all  of  the  assumptions  that  market  participants  would  use  in  pricing  the  asset  or 
liability, including assumptions about the risk inherent in a particular valuation technique, the effect of a restriction on the sale or 
use of an asset, and the risk of nonperformance. 

The Company groups its assets and liabilities measured at fair value into a three-level hierarchy, based on the markets in which 
the  assets  and  liabilities  are  traded  and  the  reliability  of  the  assumptions  used  to  determine  fair  value.  When  the  valuation 
assumptions  used  to  measure  the  fair  value  of  the  asset  or  liability  are  categorized  within  different  levels  of  the  fair  value 
hierarchy, the asset or liability is categorized in its entirety within the lowest level of the hierarchy. These levels are: 

Level 1  – Valuation is based  upon quoted prices  for identical instruments traded in active exchange  markets, such as the  New 
York  Stock  Exchange.  Level  1  includes  U.S.  Treasury  and  equity  securities,  which  are  traded  by  dealers  or  brokers  in  active 
markets.  Valuations  are  obtained  from  readily  available  pricing  sources  for  market  transactions  involving  identical  assets  or 
liabilities. 

Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar 
instruments  in  markets  that  are  not  active,  and  model-based  valuation  techniques  for  which  all  significant  assumptions  are 
observable  in  the  market.  Level  2  includes  federal  agency  securities,  mortgage-backed  securities,  corporate  securities,  asset-
backed securities, and municipal bonds.  

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

The Company relies on independent vendor pricing services to measure fair value for investment securities available  for sale and 
investment securities held to maturity. The Company employs three pricing services. To validate the pricing of these vendors, the 
Company  compares  vendors’  pricing  for  each  of  the  securities  for  consistency;  significant  pricing  differences,  if  any,  are 
evaluated  using  all  available  independent  quotes  with  the  quote  closely  affecting  the  market  generally  used  as  the  fair  value 
estimate. In addition, the Company conducts “other than temporary impairment (OTTI)” analysis on a quarterly basis; securities 
selected for OTTI analysis include all securities at a market price below 95 percent of par value. As with any valuation technique 
used  to  estimate  fair  value,  changes  in  underlying  assumptions  used  could  significantly  affect  the  results  of  current  and  future 
values. Accordingly, these fair value estimates may not be realized in an actual sale of the securities. 

The Company regularly reviews the valuation techniques and assumptions used by its vendors and determines  which valuation 
techniques  are  utilized  based  on  observable  market  inputs  for  the  type  of  securities  being  measured.  The  Company  uses  the 
information to determine the placement in the fair value hierarchy as level 1, 2 or 3. When the  Company changes its valuation 
assumptions for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions 
or other factors, or reevaluates the valuation techniques and assumptions used by its vendors, it may need to transfer those  assets 
or liabilities to another level in the hierarchy based on the new information. The Company recognizes these transfers at the end of

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, 2017 and 
December 31, 2016, the following tables provide the level of valuation assumptions used to determine each adjustment and the 
carrying value of the related assets at period end.

Level 3 – 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. 

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

Investment  Securities  Held  to  Maturity    The  fair  values  of  investment  securities  were  estimated  using  quoted  prices  as 
described above for Level 2 valuation. 

Loans  Loans were separated into two groups for valuation. Variable rate loans, except for those described below, which reprice 
frequently  with  changes  in  market  rates  were  valued  using  historical  cost.  Fixed  rate  loans  and  variable  rate  loans  that  have 
reached their minimum contractual interest rates were valued by discounting the  future cash flows expected to be received from 
the loans using current interest rates charged on loans with similar characteristics. Additionally, the allowance for loan losses of 
$23,009  thousand  at  December  31,  2017  and  $25,954  thousand  at  December  31,  2016  was  applied  against  the  estimated  fair 
values to recognize estimated future defaults of contractual cash flows.

Deposit Liabilities  Deposits with no stated maturity such as checking accounts, savings accounts and money market accounts 
can be readily converted to cash or used to settle transactions at face value through the broad financial system operated by  the 
Federal Reserve Bank and financial institutions. The fair value of deposits with no stated maturity is equal to the amount payable 
on demand. The fair values of time deposits were estimated by discounting estimated future contractual cash flows using current 
market rates for financial instruments with similar characteristics. 

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

The tables below are a summary of fair value estimates for financial instruments and the level of the fair value hierarchy within 
which the  fair value  measurements are categorized, excluding financial instruments recorded at fair value on a recurring basis. 
The values assigned do not necessarily represent amounts which ultimately may be realized for assets or paid to settle liabilities. 
In addition, these values do not give effect to adjustments to fair value which may occur when financial instruments are sold or 
settled in larger quantities.  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 $2,088  thousand  due in the 
future  under  noncancelable  subleases.  Total  rentals  for  premises  were  $6,695  thousand  in  2017,  $6,823  thousand  in  2016  and 
$8,359  thousand  in  2015.  Total  sublease  rentals  were  $406  thousand  in  2017,  $435  thousand  in  2016  and  $1,721  thousand  in 
2015. Total rentals for premises, net of sublease income, included in noninterest expense were $6,289 thousand in 2017, $6,388 
thousand in 2016 and $6,638 thousand in 2015.  

Note 13: Commitments and Contingent Liabilities 

Loan  commitments  are  agreements  to  lend  to  a  customer  provided  there  is  no  violation  of  any  condition  established  in  the 
agreement. Commitments generally have fixed expiration dates or other termination clauses. Since many of the commitments are 
expected  to  expire  without  being  drawn  upon,  the  total  commitment  amounts  do  not  necessarily  represent  future  funding 
requirements. Loan commitments are subject to the Company’s normal credit policies and collateral requirements. Unfunded loan 
commitments were $272,646 thousand and $304,508 thousand at December 31, 2017 and 2016, respectively. Standby letters of 
credit commit the Company to make payments on behalf of customers when certain specified future events occur. Standby letters 
of  credit  are  primarily  issued  to  support  customers’  short-term  financing  requirements  and  must  meet  the  Company’s  normal 
credit  policies  and  collateral  requirements.  Financial  and  performance  standby  letters  of  credit  outstanding  totaled  $19,263 
thousand and $21,732 thousand at December 31, 2017 and 2016, respectively. The Company had no commitments outstanding for 
commercial and similar letters of credit at December 31, 2017 and 2016. The Company had a reserve for unfunded commitments 
of $2,308 thousand at December 31, 2017 and $2,408 thousand at December 31, 2016, included in other liabilities. 

Due to the nature of its business, the Company is subject to various threatened or filed legal cases. Based on the advice of  legal 
counsel,  the  Company  does  not  expect  such  cases  will  have  a  material,  adverse  effect  on  its  financial  position  or  results  of 
operations. Legal liabilities are accrued when obligations become probable and the amount can be reasonably estimated.  

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

The October 2017 California wildfires have disrupted operations in the Company's geographic footprint mainly due to temporary 
power outages, unhealthy air quality, and evacuations affecting some branches and an operations center. The Company maintains 
secondary  power  generation  capability  at  its  principal  operations  center.  The  Company  maintains,  and  regularly  tests,  disaster 
recovery plans and protocols to be prepared for disasters such as these wildfires. The Company has not experienced a casualty 
loss as of the date of this report, but does carry customary casualty insurance to protect against such risk. 

Management has performed an initial evaluation of loss exposure caused by the wildfires within the Company's loan portfolio and 
investment portfolio; Management has not identified any increased risk of loss, however, continuing Management evaluations and 
further wildfire developments could result in identification of losses which are not currently apparent.

Note 14: Retirement Benefit Plans 

The  Company  sponsors  a  qualified  defined  contribution  Deferred  Profit-Sharing  Plan  covering  substantially  all  of  its  salaried 
employees  with  one  or  more  years  of  service.  The  costs  charged  to  noninterest  expense  related  to  discretionary  Company 
contributions to  the Deferred  Profit-Sharing Plan  were $944  thousand in 2017, $1,000 thousand in 2016 and $734  thousand  in 
2015. 

The  Company  also  sponsors  a  qualified  defined  contribution  Tax  Deferred  Savings/Retirement  Plan  (ESOP)  covering  salaried 
employees  who  become  eligible  to  participate  upon  completion  of  a  90-day  introductory  period.  The  Tax  Deferred  Savings/ 
Retirement Plan (ESOP) allows employees to defer, on a pretax or after-tax basis, a portion of their salaries as contributions to 
this  Plan.  Participants  may  invest  in  several  funds,  including  one  fund  that  invests  primarily  in  Westamerica  Bancorporation 
common stock. The Company funds contributions to match participating employees’ contributions, subject to certain limits. The 
matching  contributions  charged  to  compensation  expense  were  $1,098  thousand  in  2017,  $1,075  thousand  in  2016  and  $1,147 
thousand in 2015. 

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

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

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 2017 and beyond.

Note 15: Related Party Transactions  

Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries of the Company in 
the  ordinary  course  of  business.  In  Management’s  opinion,  with  the  exception  of  the  Company’s  Employee  Loan  Program,  all 
outstanding loans and commitments included in such transactions were made on substantially the same terms, including interest 
rates and collateral, as those prevailing at the time for comparable transactions with other persons, did not involve  more than a 
normal risk of collectability, and did not present other favorable features. As part of the Employee Loan Program, all employees, 
including executive officers, are eligible to receive mortgage loans at one percent below Westamerica Bank’s prevailing interest 
rate at the time of loan origination. In Management’s opinion, all loans to executive officers under the Employee Loan Program 
are made by Westamerica Bank in compliance with the applicable restrictions of Section 22(h) of the Federal Reserve Act. 

The table below reflects information concerning loans to certain directors and executive officers and/or family members during 
2017 and 2016:

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. Under this regulation,  the Bank obtained approval for dividends paid to the 
Company during 2017. The Company consistently has paid quarterly dividends to its shareholders since its formation in 1972. 

The Bank is required to  maintain reserves  with the Federal Reserve Bank equal to a  percentage  of its reservable deposits. The 
Bank’s daily average  on deposit at the  Federal Reserve Bank  was $458,186 thousand in 2017 and $365,880 thousand in 2016, 
which amounts exceed the Bank’s required reserves.

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)

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,  2017  and  2016,  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, 2017, 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, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO). 

In  our  opinion,  the  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  financial  position  of  the 
Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-
year  period  ended  December  31,  2017  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of 
America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2017, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO. 

Basis for Opinions 

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial 
reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the  accompanying 
Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s 
financial  statements  and  an  opinion  on  the  Company’s  internal  control  over  financial  reporting  based  on  our  audits.  We  are  a 
public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United  States)  ("PCAOB")  and  are 
required to be independent  with respect to the Company  in accordance with the U.S. federal securities laws and the applicable 
rules and regulations of the Securities and Exchange Commission and the PCAOB.  

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audits  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to 
error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.  

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial 
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included 
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included 
evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall 
presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding 
of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  and  testing  and  evaluating  the 
design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other 
procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audits  provide  a  reasonable  basis  for  our 
opinions. 

Definition and Limitations of Internal Control Over Financial Reporting 

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

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.

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

None. 

ITEM 9A. CONTROLS AND PROCEDURES  

The  Company’s  principal  executive  officer  and  principal  financial  officer  have  evaluated  the  effectiveness  of  the  Company’s 
“disclosure  controls  and  procedures,”  as  such  term  is  defined  in  Rule  13a-15(e)  of  the  Securities  Exchange  Act  of  1934,  as 
amended, as of December 31, 2017. 

Based  upon  their  evaluation,  the  principal  executive  officer  and  principal  financial  officer  concluded  that  the  Company’s 
disclosure controls and procedures are effective to ensure that material information required to be disclosed by the Company in 
the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported as and when required 
and  that  such  information  is  communicated  to  the  Company’s  management,  including  the  principal  executive  officer  and  the 
principal financial officer, to allow for timely decisions regarding required disclosures. The evaluation did not identify any change 
in  the  Company’s  internal  control  over  financial  reporting  that  occurred  during  the  quarter  ended  December  31,  2017  that  has 
materially  affected,  or  is  reasonably  likely  to  materially  affect,  the  Company’s  internal  control  over  financial  reporting. 
Management’s Report on Internal Control Over Financial Reporting and the attestation Report of Independent Registered Public 
Accounting Firm are found on pages 46 and 89, respectively. 

ITEM 9B. OTHER INFORMATION  

None.

registrant’s  most  recent  fiscal  quarter  (the  registrant’s  fourth  fiscal  quarter  in  case  of  an  annual  report)  that  has  materially 
affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting; 

5. The registrant’s other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over 
financial reporting, to the registrant’s auditors and the audit committee of registrant’s board of directors (or persons performing

(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting 
which  are  reasonably  likely  to  adversely  affect  the  registrant’s  ability  to  record,  process,  summarize  and  report  financial 
information; and 

(b)  Any  fraud,  whether  or  not  material,  that  involves  management  or  other  employees  who  have  a  significant  role  in  the 
registrant’s internal control over financial reporting.
