PROXY STATEMENT 
March 9, 2015 
___________

GENERAL

The  Westamerica  Board  of  Directors  is  soliciting  proxies  to  be  used  at  the  2015  Annual  Meeting  of 
Shareholders  of  Westamerica  Bancorporation,  which  will  be  held  at  11:00  a.m.  Pacific  Time,  Thursday,  
April 23, 2015, 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 9, 2015, 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 23, 2015, the 
record  date,  or  hold  a  valid  proxy  for  the  meeting.  In  order  to  be  admitted  to  the  Annual  Meeting,  the 
Corporation reserves the right to request proof of ownership of Westamerica stock on the record date. This  
can be: 

• A brokerage statement or letter from a bank or broker indicating ownership on February 23, 2015;
• 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  Corporation  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 

1

2015      WESTAMERICA BANCORPORATION PROXY2015   WESTAMERICA BANCORPORATION PROXYmatter  that  may  properly  come  before  the  Annual  Meeting  that  we  did  not  have  notice  of  by                 
January 24, 2015. 

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  23,  2015,  25,617,758 
shares  of  Westamerica  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.

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  through 
electronic mail. 

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

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

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

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

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

Beneficial  Shareholders.  If  your  shares  are  held  in  a  brokerage  account  in  the  name  of  your  bank, 
broker, or other holder of record (this is called “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  proxy, 
executed in your favor, from the holder of record to be able to vote in person at the Annual Meeting. 

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

Voting Deadlines. If you are a participant in the Westamerica Bancorporation Tax Deferred Savings/Retirement 
Plan (ESOP) your vote must be received by 11:59 p.m. Central Time, on April 20, 2015. All other shareholders 
voting by telephone or internet must vote by 1:00 a.m. Central Time, on April 23, 2015 to ensure that their vote 
is counted.

Revocation  of  Proxy.  Record  Holders  who  vote  by  proxy,  whether  by  telephone,  internet  or  mail,  may 
revoke that proxy at any time before it is voted at the Annual Meeting. You may do this by: (a) signing another 
Proxy Card with a later date and delivering it to us prior to the Annual Meeting or sending a notice of revocation 
to the Corporate Secretary of Westamerica at 1108 Fifth Avenue, San Rafael, CA 94901; (b) voting at a later 
time by telephone or on the internet prior to 1:00 a.m. Central Time, on April 23, 2015 (prior to 11:59 p.m. 
Central Time, on April 20, 2015 for ESOP participants); or (c) attending the Annual Meeting in person and casting 
a ballot. If you hold shares in street name, you may change your vote by submitting new voting instructions to your 
broker or other nominee.

Householding.  As  permitted  by  the  Securities  Exchange  Act  of  1934  (the  “Exchange  Act”)  only  one 
envelope  containing  two  or  more  Notices  of  Internet  Availability  of  Proxy  Materials  is  being  delivered  to 
shareholders  residing  at  the  same  address,  unless  such  shareholders  have  notified  their  bank,  broker, 
Computershare Investor Services, or other holder of record that they wish to receive separate mailings. If you 
are  a  beneficial  holder  and  own  your  shares  in  street  name,  contact  your  broker,  bank  or  other  holder  of 
record to discontinue householding and receive your own separate copy of the Notice in future years. If you

future  years.  To  receive  an  additional  Annual  Report  or  Proxy  Statement  this  year,  contact  Shareholder 
Relations  at  707-863-6992  or  follow  the  instructions  on  the  Notice.  Mailing  of  dividends,  dividend 
reinvestment  statements,  and  special  notices  will  not  be  affected  by  your  election  to  discontinue  duplicate 
mailings of the Notice.

THE BOARD OF DIRECTORS RECOMMEND 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  believes  that  the  most  effective  leadership  structure  for  the  Corporation  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 Corporation, 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 
Corporation  is  particularly  well  suited  to  combine  the  Chairman  and  CEO  functions.  Furthermore,  our 
management team has an average tenure of 22 years and does not require the substantial oversight needed by 
a less experienced team, which has allowed our Chairman and CEO to lead the Corporation through eleven 
acquisitions since 1992.

9

9

2015      WESTAMERICA BANCORPORATION PROXY2015   WESTAMERICA BANCORPORATION PROXY  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 
and  although  a  lead  director  has  not  been  appointed,  pertinent  information  from  these  meetings  is 
regularly communicated to the Chairman and CEO. The Board completes an annual board evaluation that 
is discussed by the Nominating Committee and presented to the full Board. 

  The Board of the Corporation also serves as the Board of Directors of Westamerica Bank, and as such 
is  well  informed  of  Bank  operations  through  regular  reports  and  discussions  on  the  operations  of  the 
Bank. The Directors’ longevity with the Corporation has exposed them to a wide range of business cycles, 
which  plays  a  critical  role  in  managing  the  risk  profile  and  profitability  of  the  Corporation  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 Corporation, including risk 
oversight,  which  is  effected  through  all  Board  committees,  but  primarily  through  the  Board’s  Audit 
Committee.  The Internal Audit Department reports directly to the Board’s Audit Committee. It presents its 
independently prepared company-wide annual risk assessment, its evaluation of Management’s prepared risk 
assessment and its audit plan incorporating the risk assessment, including the policies and procedures utilized 
to monitor and control such exposures.

  The  internal  loan  review  function  reports  directly  to  the  Board’s  Loan  and  Investment  Committee.  It 
reports  ongoing  evaluations  of  loan  portfolios  and  the  risk  rating  of  individual  loans  using  guidelines 
established by bank regulatory authorities. 

Meetings
The  Corporation  expects  all  Board  Members  to  attend  all  meetings,  including  the  Annual  Meeting  of 
Shareholders, except for reasons of health or special circumstances. The Board held a total of ten meetings 
during 2014. Every Director attended at least 75% of the aggregate of: (i) the Board Meetings held during 
that period in which they served; and (ii) the total number of meetings of any Committee of the Board on which 
the Director served. Each individual who served on the Board of the Corporation on the date of the 2014 Annual 
Meeting of Shareholders attended the meeting.

Executive Committee 
Functions: The Board delegates to the Executive Committee all powers and authority of the Board in 
the management of the business affairs of the Corporation 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 Corporation’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 
Corporation’s  financial  statements,  the  Corporation’s  compliance  with  legal  and  regulatory 
requirements, the independence and performance of the Corporation’s independent auditor as it performs 
audit,  review  or  attest  services,  and  the  Corporation’s  internal  audit  and  control  function.  It  selects  and 

11

11

2015      WESTAMERICA BANCORPORATION PROXY2015   WESTAMERICA BANCORPORATION PROXY 
 
 
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 last revised by the Board of Directors in 
April  2014  and  is  attached  as  Exhibit  A  to  the  Proxy  Statement  for  this  2015  Annual  Meeting  of 
Shareholders. The Audit Committee Report that follows below more fully describes the responsibilities 
and the activities of the Audit Committee. 

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  Corporation’s  compensation  programs  and  reviews  and  reports  to  the  Board  the 
compensation level for executive officers, including the CEO, of the Corporation 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 adopted April 24, 2013 and attached as Exhibit B to the Proxy Statement for the 2014 Annual 
Meeting of Shareholders. The Compensation Committee has the authority to seek assistance from officers 
and employees of the Corporation 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  is  governed  by  a  written  charter,  which  was  affirmed  in 
January 2013 and was attached as Exhibit A to the Proxy Statement for the 2013 Annual Meeting of 
Shareholders.  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 
Corporation’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. 

  While  the  Board  does  not  have  a  formal  diversity policy,  it  believes  that  the  Board  broadly  defines 
diversity to encompass a diverse range of skills and expertise sufficient to provide prudent guidance to 

12

12

2015   WESTAMERICA BANCORPORATION PROXY 
the  Corporation.  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 Corporation. 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 Corporation 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  Corporation  must  receive 
notice  with  a  reasonable  amount  of  time  before  the  Corporation  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 Corporation 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 Corporation 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 Corporation’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 Corporation; 
• Willingness to devote the time necessary to function effectively as a Board member; 
• Possess independence necessary to make unbiased evaluation of Management performance; 
• Be free of any conflict of interest that would violate applicable law or regulation or interfere with 

ability to perform duties; 

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

Loan and Investment Committee 
Functions: This Committee reviews major loans and investment policies.

(1)  Non-employee Directors did not receive options or stock awards. During 2014, non-employee Directors of the Corporation each received an annual 
retainer  of  $18,000.  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 2014 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  Corporation  may  make  a  nominal  donation  through  its 
Community Relations program to non-profit organizations where a Director(s) may have an affiliation.

EXECUTIVE COMPENSATION 

Compensation Discussion and Analysis

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

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

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

• Long-term  incentive  stock  grants  will  be  awarded  to  senior  management  if  the  corporate

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

– motivate senior management to focus on long-term performance;  
– avoid excessive risk-taking and instill conservative management practices; 
– build equity ownership among Westamerica’s senior management; 
– link shareholder interests to management incentives; and 
– create ownership mentality among senior management.

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

Establishing Incentive Levels, Determining Objectives and Measuring Performance 
In administering the executive compensation program, the Compensation Committee determines “target” 
incentives  for  each  position  annually.  The  Compensation  Committee  exercises  discretion  in  establishing 
“target” incentives in an effort to provide competitive pay practices while motivating and rewarding performance 
that benefits the Corporation’s long-term financial performance and shareholder interests, and avoiding 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  Corporation  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 Corporation’s balance sheet and product pricing 
in a manner which will provide consistent sustainable growth in long-term financial results for shareholders, 
the  type  and  variety  of  financial  products  offered  by  the  Corporation,  adherence  to  internal  controls, 
management  of  the  credit  risk  of  the  Corporation’s  loan  and  investment  portfolios,  the  results  of  internal, 
regulatory  and  external  audits,  service  quality  delivered  to  the  Corporation’s  customers,  service  quality  of 
“back office” support departments provided to those offices and departments directly delivering products and 
services  to  the  Corporation’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’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  Corporation’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 
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 Corporation 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 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 

16

16

2015   WESTAMERICA BANCORPORATION PROXY 
exercised, the optionee incurs taxable income equal to the spread between the exercise price and the 
market price of the stock, and the Corporation 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  Corporation’s  common  stock  on  the  date  the  SAR  is  surrendered  and  the  fair 
market  value  of  the  Corporation’s  common  stock  on  the  date  the  SAR  was  granted.  The  optionee  incurs 
taxable income at the time the SAR is settled and the Corporation receives a corporate tax deduction in 
the same amount. 

Restricted Performance Share Grants, as noted above, are awards of the Corporation’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 Corporation 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 
Corporation. As of February 24, 2015, the Corporation 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 Corporation’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 
Corporation’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 Corporation has broadly 
disseminated its financial condition and current operating results to the public. The Corporation’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.(1)

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: 

(1) Due to merger and acquisition activity, the Corporation converts stock option grants outstanding for acquired companies based on the terms and 
conditions of related merger agreements. The dating of such converted stock options generally remains as originally dated by the acquired company. As 
a result, the Corporation at times has options outstanding related to acquisitions with grant dates different from its routine stock option granting practices.

• 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 Corporation 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 Corporation 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  Corporation.  These  two  functions  tend  to  be  compensated 
separately  at  similarly  sized  banking  institutions.  Mr.  Payne  serves  as  Chairman  of  the  Board  and  Chief 
Executive  Officer  with  responsibilities  including  oversight  of  the  organization  and  external  strategic 
initiatives.  Mr.  Payne  also  serves  as  President  and  Chief  Operating  Officer  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 28 of the Proxy under the Pension Benefits Table, during 1997 the Corporation 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.(2)  In  entering  the 
Pension Agreement, the Board of Directors considered the following: 

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

• In 1997, the Corporation 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 
Chief  Executive  Officer  was  desired  following  the  Corporation’s  significant  growth.  The  RPS 
shares surrendered for the Pension Agreement were scheduled to vest on dates in 1998, 1999 and 
2000, while the Pension Agreement was not fully vested until December 31, 2002. Additionally, the 
20-year certain pension provided under the Pension Agreement was to commence upon Mr. Payne’s 
attainment of age 55. Mr. Payne was age 42 at the time of entering the Pension Agreement. 

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

“Target” 
Cash 
Incentive 

X 

Composite Corporate 
Divisional and Individual 
Performance Level 

= 

Cash 
Incentive 
Award 

     In  structuring  performance  goals  for  the  named  executive  officers,  the  Compensation  Committee 
emphasizes goals, which if achieved, will benefit the overall Corporation. 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 2014 performance were as follows: 

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

     The Compensation Committee establishes corporate goals with the intent to balance current profitability 
with long-term stability of the Corporation and its future earnings potential. The 2014 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  Corporation  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  2014,  the  Compensation  Committee  expected  nominal  economic  growth  within  the  markets  the 
Company operates given the slow pace of recovery from the severe recession of 2008 and 2009. 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 2014 operating environment was generally characterized as 
follows:

• The economy  generally grew in-line with economic forecasts. Inflation remained below targets 
established by the Federal Open Market Committee. Employment trends continued to improve; 
• The Federal Reserve’s monetary policies continued to influence United States-based interest rates 
to remain at relatively low levels, and the spread between three-month and ten-year Treasury debt 
compressed throughout 2014; 

• Interest rates on loans and investment securities remain relatively low compared to interest rates 
which would exist with moderated economic conditions. Market interest rates remained below the 
yields  on  the  Company’s  overall  loan  and  investment  portfolios  throughout  2014.  Competitive 
pricing of loans was aggressive; 

• Regulations  imposed  on  financial  institutions  continued  to  pressure  compliance  costs,  revenue 

opportunities, and operational risks. 

• Deflation concerns in foreign developed economies resulted in monetary policy easing in many 

countries;

• Management  consistently  maintained  conservative  loan  underwriting  practices  to  appropriately 

manage the Company’s exposure to credit risk;

• Management focused its marketing efforts on loan products that would provide improved revenue 

opportunities in a rising interest rate environment; 

• Management avoided long-duration, low-yielding loans that would constrain revenue in a rising 

interest rate environment; 

• Management  increased  the  volume  of  interest-sensitive  investment  securities  to  prepare  for  rising 

interest rates on a forward basis; 

• Management  controlled  operating  costs  to  offset  the  effect  of  environmental  pressures  on 

revenues;

• Management continued to lower the cost of funding the loan and investment securities portfolios; 
• Management pursued growth in non-interest based sources of revenue; and 
• Adequate capital levels were maintained to position the Company for future growth.

     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 111.5% of target goals.

     RPS awards vest three years following the grant date, only if certain corporate performance objectives are 
achieved over the three-year period. In January 2015, the Compensation Committee evaluated whether the 
three  year  corporate  performance  objectives  were  met  for  RPS  awards  granted  in  January  2012.  The 
performance objectives for the RPS granted in January 2012 included: 
• 3 year cumulative diluted earnings per share (EPS); 
• 3 year average of annual return on average total assets (ROA); 
• 3 year  average  of  annual  return  on  average  shareholders’  equity  relative  to  industry  average 

ROE (ROE differential); 

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

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

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

     With two of the five goals achieved at the “outstanding” performance level, the Compensation Committee 
determined the RPS shares awarded in 2012 vested upon achievement of three year goals. 

Nonqualified Deferred Compensation Programs 
The Corporation 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  Corporation’s 
“401(k)” plan. The Corporation 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 Corporation 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 Corporation. 

• The common stock the Corporation 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 Corporation’s common stock, the Corporation 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 Corporation’s creditors. 

Employment Contracts 
None of the executives named in the accompanying tables have employment contracts with the Corporation. 

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 Corporation after any “change in control” 
was announced through its ultimate consummation. Since none of the named executive officers have entered 
employment  contracts  with  the  Corporation,  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  Corporation  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  Corporation  in  any  year  with  respect  to  certain  of  the  Corporation’s  highest-paid 
executives.  Certain  “performance-based  compensation”  is  not  counted  toward  this  limit.  The  Corporation 
intends  generally  to  qualify  compensation  paid  to  executive  officers  for  deductibility  under  the  IRC, 
including  Section  162(m),  but  reserves  the  right  to  pay  compensation  that  is  not  deductible.

Non-Qualified Pension Agreement

$5,835,629

$511,950

During 1997, the Corporation 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 Corporation’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  3.80%,  as  used  by  the  Corporation  in 
determining benefit obligations for its post-employment retirement benefits as of December 31, 2014. The 
obligation is an unfunded general obligation of the Corporation.

2015   WESTAMERICA BANCORPORATION PROXY 
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 2014 was 5.60%. 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  Corporation  or  a  sale  of  substantially  all  of  the  Corporation’s  assets  to  another 
corporation, or a tender offer for 5% or more of the Corporation’s outstanding common stock or a merger 
in  which  the Corporation’s shareholders before the  merger hold less than 50% of the voting power of the 
surviving corporation 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: $490,944; Robinson: $494,562; Ms. Finger: $490,944; and Messr. Hansen: 
$442,336. The value is computed by multiplying the difference between the market value on December 31, 2014, 
the  last  business  day  of  2014,  and  the  exercise  price  of  each  option  by  the  number  of  shares  subject  to     

29

29

2015      WESTAMERICA BANCORPORATION PROXY2015   WESTAMERICA BANCORPORATION PROXY 
accelerated vesting.

  Under the Corporation’s Severance Payment Plan, executive officers receive six weeks pay for every year 
or partial year of service up to one year’s base salary (see Summary Compensation Table for Fiscal Year 
2014 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 Corporation. The Severance Payment Plan is subject to Section 409A of the Internal 
Revenue Code. 

Certain Relationships and Related Party Transactions

In accordance with the Audit Committee Charter, the Audit Committee is responsible for reviewing and 
approving or disapproving all related party transactions required to be disclosed by Item 404 of Regulation  
S-K for potential conflicts of interest. Additionally, the Corporation’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 Corporation in the ordinary course of business. With the exception of the Corporation’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  Corporation,  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.  Hansen,  Payne  and 
Thorson have mortgage loans through this Program. The largest aggregate amount of principal during 2014 
was  $244,716,  $442,152,  and  $325,741, 
December  31,  2014  was  $234,596,  $423,287,  and  $299,280,  respectively.  The  amount  of  principal  paid 
during 2014 was $10,120, $18,865, and $26,462, respectively. The amount of interest paid during 2014 was 
$4,527, $8,129, and $5,889, respectively. The rate of interest payable on the loan is 1.875%, 1.875%, and 
1.875%, respectively.

PROPOSAL 2 – APPROVE A NON-BINDING ADVISORY VOTE
ON THE COMPENSATION 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 98% 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 2017, six years after the first frequency vote.  

  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 

30

30

2015   WESTAMERICA BANCORPORATION PROXY 
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 Corporation’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  Corporation’s  2012  Amended  and  Restated  Stock  Option  Plan  of 

1995.  The 2012 Plan includes the following changes: 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 Plan to April 24, 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,

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

PROPOSAL 3 – RATIFY SELECTION OF INDEPENDENT AUDITOR 

  The  Audit  Committee  has  approved  the  selection  of  the  firm  of  Crowe  Horwath  LLP  to  serve  as 
independent auditors for 2015 to examine the consolidated financial statements of the Corporation. 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 Corporation and its shareholders. If the proposal to ratify the 
selection of Crowe Horwath LLP as the Corporation’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 Corporation by KPMG LLP, the independent audit firm for fiscal 2014 
and 2013, with respect to services performed are as follows:

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 Corporation for the purpose of preparing or issuing an audit 
report or performing other audit, review or attest services for the Corporation. Any accounting firm appointed 
by the Corporation 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  Corporation  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 
Corporation during the fiscal year in which the services are provided. This exception also requires that at the 
time of the engagement, the Corporation did not recognize such services to be non-audit services, and such 
services are promptly brought to the attention of the Audit Committee and approved prior to the completion 
of  the  audit  by  the  Audit  Committee.  During  fiscal  year  2014,  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 

(4) Audit fees consisted of fees billed by KPMG for professional services rendered for the audit of the Corporation’s consolidated financial statements, 
reviews of the consolidated financial statements included in the Corporation’s quarterly reports on Form 10-Q, and the audit of the Corporation’s internal 
controls over financial reporting. The audit fees also relate to services such as consents and audits of mortgage banking subsidiaries.

The  Audit  Committee  preapproved  100%  of  all  services  performed  on  behalf  of  the  Corporation  by 
KPMG LLP during fiscal year 2014.

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  Corporation’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 
Corporation, and who meet the NASDAQ independence requirements for Audit Committee members. The 
Audit Committee selects, appoints and retains the Corporation’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 Corporation’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 Corporation’s annual financial statements to generally accepted accounting principles. In 
fulfilling  its  oversight  responsibilities,  the  Audit  Committee  reviewed  the  audited  consolidated  financial 
statements for the fiscal year 2014 and discussed them with Management and with KPMG, the Corporation’s 
independent auditors. 

     Management represented to the Audit Committee that the Corporation’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, 2014, and that internal control over financial reporting was effective. The Audit Committee 
discussed  with  the  auditors  matters  required  to  be  discussed  by  Statement  on  Auditing  Standards  No.  114 
(The  Auditor’s  Communication  with  Those  Charged  with  Governance)  as  amended,  including  the 
auditors’ judgment about the quality as well as the acceptability of the Corporation’s accounting principles, 
as applied in its financial reporting. 

  The  auditors  also  provided  to  the  Audit  Committee  the  written  disclosures  and  the  letter  from  the 
independent  auditors  required  by  Independence  Standards  Board  Standard  No.  1  (Independence 
Discussions  with  Audit  Committees).  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 Corporation’s Annual Report on Form 10-K for the year ended 
December 31, 2014 for filing with the SEC.

EXHIBIT A 
Westamerica Bancorporation 
Audit Committee Charter – Approved April, 2014 

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    and  (4)  the  Company’s 
internal  audit  and  control  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, 
income  statement  and  cash  flow  statement,  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.

nificant parts of the audit will be performed by other auditors;

the scope of activities or access to required information; 

(j) any significant disagreements with management. 

6. Annually review with the independent auditor the quality of the Company’s financial reporting, 
internal accounting and financial control, the auditor’s report or opinion thereon and any recom-
mendations the auditor may have for improving or changing the Company’s internal controls, as 
well  as  management’s  letter  in  response  thereto  and  any  other  matters  required  to  be  discussed

formation and earnings guidance provided to analysts and rating agencies, if any, as well as any 
financial  information  which  the  Company  proposes  to  provide  to  financial  analysts  and  rating 
agencies (being mindful of the need to avoid violations of SEC Regulation FD, which prohibits

12. Discuss  the  quarterly  and  annual  financial  statements  with  the  appropriate  officers  and/or  em-

management or other employees who have a significant role in the Company’s internal controls. 

17. Review the effect of regulatory and accounting initiatives on the financial statements of the Com-

pany.

Oversight of the Company’s Relationship with its Independent Auditors

18. Review and evaluate the experience and qualifications of the lead members of each independent 

auditor’s team. 

19. Evaluate the performance and independence of each independent auditor, including considering 
whether the auditor’s quality controls are adequate and the provision of permitted non-audit ser-

and the internal auditor 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 inde-
pendent auditor’s independence and discuss such reports with the auditor.  Ensure that each inde-
pendent 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  inde-
pendent auditor’s internal quality control procedures.  The report should include any material is-
sues raised by the most recent internal quality control review or peer review of the firm, or by any 
inquiry  or  investigation  by  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.

Oversight of the Company’s Internal Audit Function

27. Review  and,  at  its  option,  recommend  the  appointment  and  replacement  of  the  senior  internal 

auditing executive. 

28. Review any reports to management prepared by the internal auditing department and management’s 

responses.

29. Review with each independent auditor, management and the senior internal auditing executive the 
internal  audit  department  responsibilities,  budget,  structure  and  staffing  and  any  recommended 
changes in the planned scope of the internal audit at least annually.

matters.

33. Discuss  with  management  and  each  independent  auditor  any  correspondence  with  regulators  or

FORWARD-LOOKING STATEMENTS 

This  report  on  Form  10-K  contains  forward-looking  statements  about  Westamerica  Bancorporation  for  which  it  claims  the 
protection of the safe harbor provisions contained in the Private Securities Litigation Reform Act of 1995. Examples of forward-
looking statements include, but are not limited to: (i) projections of revenues, expenses, income or loss, earnings or loss per share, 
the  payment  or  nonpayment  of  dividends,  capital  structure  and  other  financial  items;  (ii) statements  of  plans,  objectives  and 
expectations  of  the  Company  or  its  management  or  board  of  directors,  including  those  relating  to  products  or  services; 
(iii) statements of future economic performance; and (iv) statements of assumptions underlying such statements.  Words such as 
"believes",  "anticipates",  "expects",  "intends",  "targeted",  "projected",  "continue",  "remain",  "will",  "should",  "may"  and  other
similar  expressions  are  intended  to  identify  forward-looking  statements  but  are  not  the  exclusive  means  of  identifying  such 
statements. 

These forward-looking statements are based on Management’s current knowledge and belief and include information concerning 
the Company’s possible or assumed future financial condition and results of operations. A number of factors, some of which are 
beyond the Company’s ability to predict or control, could cause future results to differ materially from those contemplated. These
factors include but are not limited to (1) the length and severity of 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 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, fire, flood, drought, and other disasters, on the uninsured 
value 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,  and  (13)  changes  in  the  securities  markets.  The  Company 
undertakes no obligation to update any forward-looking statements in this report. 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  corporate  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.

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
On February 6, 2009, Westamerica Bank acquired the banking operations of County Bank (“County”) from the Federal Deposit 
Insurance  Corporation  (“FDIC”).  The  Bank  and  the  FDIC  entered  loss-sharing  agreements  regarding  future  losses  incurred  on 
acquired  loans  and foreclosed  loan  collateral.  Under  the  terms  of  the  loss-sharing  agreements,  the  FDIC  absorbs  80  percent of 
losses and is entitled to 80 percent of loss recoveries on the first $269 million of losses, and absorbs 95 percent of losses and is 
entitled  to  95  percent  of  loss  recoveries  on  losses  exceeding  $269  million.  The  term  for  loss-sharing  on  residential  real  estate
loans is ten years, while the term for loss-sharing on non-residential real estate loans is five years in respect to losses and eight 
years  in  respect  to  loss  recoveries.  The  FDIC  indemnification  expired  February  6,  2014  for  County  Bank  non-single-family 
residential collateralized purchased loans. 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.  

Management made significant estimates and exercised significant judgment in accounting for these 2009 and 2010 acquisitions. 
Management judgmentally measured loan fair values based on loan file reviews (including borrower financial statements and tax 
returns), appraised collateral values, expected cash flows, and  historical loss factors. Repossessed loan collateral was primarily
valued based upon appraised collateral values. The Bank also recorded identifiable intangible assets representing the value of the 
core  deposit  customer  bases  based  on  Management’s  evaluation  of  the  cost  of  such  deposits  relative  to  alternative  funding 
sources. In determining the value of the identifiable intangible assets, Management used significant estimates including average
lives  of  deposit  accounts,  future  interest  rate  levels,  the  cost  of  servicing  various  depository  products,  and  other  significant
estimates. Management used quoted market prices to determine the fair value of investment securities, FHLB advances and other 
borrowings which were purchased and assumed. 

At  December  31,  2014,  the  Company  had  consolidated  assets  of  approximately  $5.0  billion,  deposits  of  approximately  $4.3 
billion  and  shareholders’  equity  of  approximately  $527  million.  The  Company  and  its  subsidiaries  employed  858  full-time 
equivalent staff as of December 31, 2014. 

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 
(http://www.sec.gov). Such documents as well as the Company’s director, officer and employee Code of Conduct and Ethics are

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.

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY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.

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
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  implements  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

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. 

Many aspects of the Dodd-Frank Act are subject to rulemaking and implementation of new regulations and will take effect over 
several years, making it difficult to anticipate the overall financial impact on the Company, its customers or the financial industry 
more  generally.  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  100%  for  assets  with  relatively  higher  credit  risk,  such  as
certain loans. 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

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY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,  2014,  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 the standards for well
capitalized depository institutions and for minimum capital requirements. 

On July 2, 2013, the Federal Reserve Board approved a final rule that implements changes to the regulatory capital framework for
all  banking  organizations.  See  the  section  entitled  “Capital  to  Risk-Adjusted  Assets”  in  Item  7.  Management’s  Discussion  and 
Analysis  of  Financial  Condition  and  Results  of  Operations  for  the  Company’s  interpretation  of  the  final  rule  in  regard  to  its 
capital ratios. 

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

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. 

FDICIA  also  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  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.

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
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  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. 

Premiums for Deposit Insurance

Substantially  all  of  the  deposits  of  the  Bank  are  insured  up  to  applicable  limits  by  the  Deposit  Insurance  Fund  ("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 October 2010, the FDIC adopted a new DIF restoration plan to ensure that the DIF reserve ratio reaches 1.35% by September 
30, 2020, as required by the Dodd-Frank Act. At least semi-annually, the FDIC will update its loss and income projections for the
fund and, if needed, will increase or decrease assessment rates, following notice-and-comment rulemaking if required. 

In February 2011, the FDIC issued a final rule changing the deposit insurance assessment base from total domestic deposits to 
average total assets minus average tangible equity, as required by the Dodd-Frank Act, effective April 1, 2011. The FDIC also 
issued a final rule revising the deposit insurance assessment system for “large” institutions having more than $10 billion in assets
and another for "highly complex" institutions that 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. Under the new assessment rules, the initial base
assessment  rates  range  from  5  to  35  basis  points,  and  after  potential  adjustments  for  unsecured  debt  and  brokered  deposits, 
assessment rates range from 2.5 to 45 basis points. 

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

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY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.

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
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.

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY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 25.7 million shares of common stock were outstanding at December 31, 2014. Pursuant to its stock option plans, at
December 31, 2014, the Company had outstanding options for 1.9 million shares of common stock, of which 1.4 million were 
currently  exercisable.  As  of  December  31,  2014,  1.2  million  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,  2014,  approximately  1.7  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 affected 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, 2014, real estate served as the principal source of collateral with respect to approximately 52% 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 is recovering from a severe recession. 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  been  recovering  from  the  recent  recession  more  soundly  than  counties  in  the  California  “Central  Valley,” 
from Sacramento in the north to Bakersfield in the south. Approximately 27% of the Company’s loans are to borrowers in the 
California “Central Valley.” Economic conditions in California are subject to various uncertainties at this time, including the pace 
of recovery in construction and real estate sectors, the effect of drought on the agricultural sector and its infrastructure, and the 
California state government’s budgetary difficulties and fiscal condition. The Company can provide no assurance that conditions
in 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 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.  California  is  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  borrowers  may 
experience uninsured property losses, or sustained job interruption and/or loss which may materially impair their ability to meet
the terms of their loan obligations. A major earthquake, flood, prolonged drought, fire or other natural disaster in California 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;  
a decrease in the amount of deposits; 
a decrease in non-depository funding available to the Company; 
an impairment of certain intangible assets, such as 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, 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 recent 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. Weak economic conditions can significantly weaken the strength and liquidity of financial institutions.

The Company’s financial performance generally, and in particular the ability of borrowers to pay interest on and repay principal
of outstanding loans and the value of collateral securing those loans, is highly dependent upon on 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 or interest rates; natural disasters; or a combination of these or other factors. 

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

Regulatory Risks

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

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

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY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. As an example, the FRB amended Regulation E, which implements the Electronic Fund 
Transfer Act, in a  manner that limits the ability of a financial institution to assess an overdraft fee for paying automated teller 
machine  (ATM)  and  one-time  debit  card  transactions  that  overdraw  a  consumer’s  account,  unless  the  consumer  affirmatively 
consents,  or  opts  in,  to  the  institution’s  payment  of  overdrafts  for  these  transactions.  Implementation  of  the  new  provisions 
significantly reduced overdraft fees assessed by the Bank. 

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. 

Recently,  the  FRB  has  been  providing  vast  amounts  of  liquidity  into  the  banking  system  due  to  current  economic  and  capital 
market  conditions.  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 
activities in the fourth quarter 2013 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. 

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

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
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, 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.

Yields on securities and certain loans have been adjusted upward to a “fully taxable equivalent” (“FTE”) basis, which is a non-GAAP financial measure, in 
order to reflect the effect of income which is exempt from federal income taxation at the current statutory tax rate. 
The  efficiency  ratio  is  defined  as  noninterest  expense  divided  by  total  revenue  (net  interest  income  on  an  FTE  basis,  which  is  a  non-GAAP  financial 
measure, 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 50 through 88,
as well as with the other information presented throughout the 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

During  the  three  years  ended  December  31,  2014,  market  interest  rates  declined  and  remained  at  low  levels.  The  Federal 
Reserve’s Federal Open Market Committee has maintained highly accommodative monetary policies to influence interest rates to 
low levels in order to provide stimulus to the economy following the “financial crisis” recession. The Company’s principal source 
of revenue is net interest and fee income, which represents interest earned on loans and investment securities (“earning assets”) 
reduced  by  interest  paid  on  deposits  and  other  borrowings  (“interest-bearing  liabilities”).  The  relatively  low  level  of  market 
interest rates has reduced the spread between interest rates on earning assets and interest bearing liabilities. The Company’s net 
interest margin and net interest income declined as market interest rates on newly originated loans remain below the yields earned 
on older-dated loans and on the overall loan portfolio. The Company is reducing its exposure to rising interest rates by purchasing 
shorter-duration investment securities with lower yields than longer-duration securities. The Company’s credit quality continued
to improve, as nonperforming assets declined thirty percent in the twelve months ended December 31, 2014 and net loan losses 
declined in 2014 compared with 2013. The improvement in credit quality has resulted in Management reducing the provision for 
loan  losses  by  sixty-five  percent  in  the  twelve  months  ended  December  31,  2014  compared  with  2013.  The  credit  quality 
improvement  also  contributed  to  reducing  noninterest  expenses  related  to  nonperforming  assets.  Management  is  focused  on 
controlling all noninterest expense levels, particularly due to market interest rate pressure on net interest income. 

The Company reported net income of $60.6 million or $2.32 diluted earnings per common share for the year ended December 31, 
2014 compared with net income of $67.2 million or $2.50 diluted earnings per common share for the year ended December 31, 
2013 and net income of $81.1 million or $2.93 diluted earnings per common share for the year ended December 31, 2012.

Comparing  2014  with  2013,  net  income  decreased  $6.5  million  primarily  due  to  lower  net  interest  and  fee  income  (FTE)  and 
lower  noninterest  income,  partially  offset  by  decreases  in  the  provision  for  loan  losses,  noninterest  expense  and  income  tax 
provision  (FTE).  The  lower  net  interest  and  fee  income  (FTE)  was  primarily  caused  by  a  lower  average  volume  of  loans  and 
lower yields on interest earning assets, partially offset by higher average balances of investments and lower average balances of 
higher-costing interest-bearing liabilities. The provision for loan losses was reduced, reflecting Management's evaluation of losses
inherent in the loan portfolio. Lower noninterest income was mostly attributable to lower merchant processing service fees, lower 
service  charges  on  deposit  accounts  and  the  recognition  in  2013  of  a  loan  principal  recovery  exceeding  the  purchase  date  fair 
value  (included  in  “other  noninterest  income”).  Noninterest  expense  decreased  mostly  due  to  reduced  OREO  expense  net  of 
disposition  gains,  personnel  costs,  loan  administration  expenses,  professional  fees  and  limited  partnership  operating  losses 
(included in “other noninterest expense”). 

Comparing 2013 to 2012, net income decreased $14.0 million or 17.2%, primarily due to lower net interest and loan fee income 
(FTE), partially offset by decreases in loan loss provision, noninterest expense and income tax provision (FTE). The lower net 
interest and loan fee income (FTE) was primarily caused by a lower average volume of loans and lower yields on interest-earning
assets, partially offset by higher average balances of investments, lower average balances of interest-bearing liabilities and lower 
rates paid on interest-bearing deposits. The provision for loan losses was reduced, reflecting Management's evaluation of losses
inherent  in  the  loan  portfolio;  net  loan  losses  and  nonperforming  loan  volumes  have  declined  relative  to  earlier  periods. 
Noninterest expense decreased $4.3 million primarily due to reduced personnel costs, professional fees, loan administration costs,
expenses related to other real estate owned and intangible asset amortization. 

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  2014 with 2013, net interest and fee income (FTE) decreased $15.1 million or 9.0% primarily due to a lower average

higher average balances of investments (up $206 million) and lower average balances of higher-costing interest-bearing liabilities.

Comparing 2013 with 2012, net interest and loan fee income (FTE) decreased $29.3 million or 14.9%, primarily due to a lower 
average volume of loans (down $360 million) and lower yields on interest-earning assets (down 74 bp), partially offset by higher
average balances of investments (up $355 million), lower average balances of interest-bearing liabilities (down $161 million) and 
lower rates paid on interest-bearing deposits (down 2 bp).

Loan volumes  have declined  due  to  problem  loan workout  activities  (such  as  chargeoffs, collateral  repossessions  and principal 
payments), particularly with purchased loans, and reduced volumes of loan originations. In Management’s opinion, current levels
of competitive loan pricing do not provide adequate forward earnings potential. As a result, the Company has not currently taken
an  aggressive  posture  relative  to  loan  portfolio  growth.  Management  has  maintained  relatively  stable  interest-earning  asset 
volumes by increasing investment securities as loan volumes have declined. 

Yields  on  interest-earning  assets  have  declined  due  to  relatively  low  interest  rates  prevailing  in  the  market.  The  net  interest
margin (FTE) was 3.70% in 2014, 4.08% in 2013 and 4.79% in 2012. During the three years ended December 31, 2014, the net 
interest margin (FTE) was affected by declining market interest rates. The volume of older-dated higher-yielding loans declined
due  to  principal  maturities  and  paydowns.  Newly  originated  loans  have  lower  yields.  The  Company,  in  anticipation  of  rising 
interest rates, has been purchasing floating rate and 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 
once market interest rates start rising. The Company has been purchasing securities of U. S. government sponsored entities which
have  call  options;  the  issuing  entities  have  been  exercising  the  call  options,  and  the  Company  has  re-invested  the  proceeds  at 
higher rates; interest rates in the two to five-year time horizon have increased throughout 2014. 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 and by reducing the
volume  of  higher-cost  funding  sources.  A  $15  million  long-term  note  was  repaid  in  October  2013  and  a  $10  million  term 
repurchase  agreement  was  repaid  in August  2014. Average  balances of  time  deposits  declined  $134 million  in  2014  compared 
with  2013.  Lower-cost  checking  and  savings  deposits  accounted  for  89.8%  of  total  average  deposits  in  2014  compared  with 
86.3% in 2013 and 82.8% in 2012.  

Comparing 2014 with 2013, interest and fee income (FTE) was down $16.3 million or 9.5%. The decrease resulted from a lower 
average volume of loans and lower yields on interest-earning assets, partially offset by higher average balances of investments.
Average  balances  of  loans  decreased  $182  million  primarily  attributable  to  decreases  in  average  balances  of  commercial  real 
estate loans (down $105 million), consumer installment and other loans (down $54 million), residential real estate loans (down 
$40  million)  and  tax-exempt  commercial  loans  (down  $19  million),  partially  offset  by  a  $40  million  increase  in  the  average 
balance  of  taxable  commercial  loans.  The  average  investment  portfolio  increased  $206  million  mostly  due  to  higher  average 
balances of U.S. government sponsored entities (up $284 million) and corporate securities (up $55 million), partially offset by a 
$105 million decrease in average balances of collateralized mortgage obligations and mortgage-backed securities.  

The  average  yield  on  earning  assets  in  2014 was  3.78%  compared  with  4.19%  in 2013.  The  loan portfolio  yield  for 2014  was 
5.12% compared with 5.36% for 2013 due to lower yields on taxable commercial loans (down 89 bp), consumer installment and 
other  loans  (down  28  bp),  commercial  real  estate  loans  (down  9  bp),  construction  loans  (down  189  bp)  and  tax-exempt 
commercial  loans  (down  13  bp).  Nonperforming  loans  are  included  in  average  loan  volumes  used  to  compute  loan  yields; 
fluctuations in nonaccrual loan volumes impact loan yields. The yield on construction loans in 2013 was elevated due to higher 
interest received on nonaccrual loans and discount accretion on purchased loans. The investment portfolio yield decreased 37 bp
to  2.76%  primarily  due  to  lower  yields  on  municipal  securities  (down  46  bp)  and  corporate  securities  (down  19  bp),  partially 
offset by higher yields on securities of U.S. government sponsored entities (up 44 bp). The yield on securities of U.S. government 
sponsored entities rose as securities added to the portfolio in 2014 were higher yielding than securities held in the prior period. 

Comparing  2014  with  2013,  interest  expense  declined  $1.2  million  or  26.3%  due  to  lower  average  balances  of  higher-costing 
interest-bearing liabilities. Average balances of debt financing and Federal Home Loan Bank advances declined $12 million and 
$5 million, respectively. Average balances of interest-bearing deposits decreased primarily due to lower average balances of time 
deposits $100 thousand or more (down $104 million), time deposits less than $100 thousand (down $30 million) and preferred 
money market savings (down $10 million), partially offset by higher average balances of money market savings (up $54 million), 
money market checking accounts (up $32 million), and regular savings (up $20 million). Rates paid on interest-bearing liabilities 
averaged 0.14% in 2014 compared with 0.18% in 2013. Rates paid on interest-bearing deposits were 0.12% in 2014 compared 
with 0.14% in 2013. 

In 2013, interest and loan fee income (FTE) was down $30.4 million or 15.0% from 2012. The decrease resulted from a lower 
average volume of loans and lower yields on interest-earning assets, partially offset by higher average balances of investments.
The total average balances of loans declined due to decreases in the average balances of commercial real estate loans (down $155
million), taxable commercial loans (down $63 million), consumer loans (down $57 million), residential real estate loans (down 
$53  million),  tax-exempt  commercial  loans  (down  $22  million)  and  construction  loans  (down  $11  million).  The  average 
investment  portfolio  increased  largely  due  to  higher  average  balances  of  corporate  securities  (up  $205  million),  collateralized
mortgage  obligations  (up  $172  million)  and  municipal  securities  (up  $47  million),  partially  offset  by    decreases  in  average 
balances  of  mortgage  backed  securities  (down  $37  million)  and  securities  of  U.S.  government  sponsored  entities  (down  $30 
million).

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXYThe  average  yield  on  the  Company's  earning  assets  decreased  from  4.93%  in  2012  to  4.19%  in  2013.  The  composite  yield  on 
loans declined 41 bp to 5.36% mostly due to lower yields on commercial real estate loans (down 45 bp), consumer loans (down 
62 bp),  residential  real  estate  loans  (down  14  bp),  taxable  commercial  loans  (down  8  bp)  and  tax-exempt  loans  (down  20  bp). 
Nonperforming loans are included in average loan volumes used to compute loan yields; fluctuations in nonaccrual loan volumes 
impact  loan  yields.  The  yield  on  construction  loans  in  2013  was  elevated  due  to  interest  received  on  nonaccrual  loans  and 
discount accretion on purchased loans. The investment yields in general declined due to market rates. The investment portfolio 
yield decreased 71 bp to 3.13% in 2013 primarily due to lower yields on collateralized mortgage obligations and mortgage backed
securities (down 65 bp), municipal securities (down 55 bp) and corporate securities (down 46 bp). 

Comparing 2013 with 2012, interest expense declined $1.1 million or 18.7% due to lower average balances of interest-bearing 
liabilities  and  lower  rates  paid  on  interest-bearing  deposits. Lower-cost  checking  and  savings  deposits  accounted  for  86.3%  of 
total  average  deposits  in  2013  compared  with  82.8%  in  2012.  Average  interest-bearing  liabilities  fell  $161  million  in  2013 
compared  with  2012  primarily  due  to  declines  in  the  average  balances  of  time  deposits  $100  thousand  or  more  (down  $120 
million) and time deposits less than $100 thousand (down $36 million), preferred money market accounts (down $23 million) and 
customer  sweep  accounts  (down  $23  million),  partially  offset  by  increases  in  the  average  balances  of  regular  savings  (up  $25 
million) and money market savings (up $17 million). Rates paid on interest-bearing deposits averaged 0.14% in 2013 compared 
with 0.16% for 2012 as a result of decreases in rates paid on time deposits less than $100 thousand (down 10 bp).

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
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 current statutory tax rate.

Provision for Loan Losses

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

The Company provided $2.8 million, $8.0 million and $11.2 million for loan losses in 2014, 2013 and 2012, respectively. The 
reduced  provision  for  loan  losses  for  2014  and  2013  reflects  Management’s  current  evaluation  of  credit  quality  for  the  loan 
portfolio.  The  Company  recorded  purchased  County  Bank  and  Sonoma  Valley  Bank  loans  at  estimated  fair  value  upon  the 
acquisition dates, February 6, 2009 and August 20, 2010, respectively. Such estimated fair values were recognized for individual
loans,  although  small  balance  homogenous  loans  were  pooled  for  valuation  purposes.  The  valuation  discounts  recorded  for 
purchased  loans  included  Management’s  assessment  of  the  risk  of  principal  loss  under  economic  and  borrower  conditions 
prevailing  on  the  dates  of  purchase.  The  purchased  County  Bank  loans  secured  by  single-family  residential  real  estate  are 
“covered”  through  February  6,  2019  by  loss-sharing  agreements  the  Company  entered  with  the  FDIC  which  mitigates  losses 
during the term of the agreements. The FDIC indemnification of purchased County Bank non-single-family residential real estate 
secured  loans  expired  February  6,  2014.  Any  deterioration  in  estimated  value  related  to  principal  loss  subsequent  to  the 
acquisition dates requires additional loss recognition through a provision for loan losses. No assurance can be given that future 
provisions for loan losses related to purchased loans will not be necessary. 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 Credit Losses” sections of this report.

In 2014, noninterest income decreased $5.2 million or 9.2% compared with 2013. Merchant processing services fees decreased 
$1.8  million  primarily  due  to  customer  attrition  and  lower  transaction  volumes.  Service  charges  on  deposits  decreased  $1.5 
million compared with 2013 primarily due to declines in fees charged on overdrawn and insufficient funds accounts (down $1.0 
million) and lower activity on checking accounts (down $410 thousand). ATM processing fees decreased $285 thousand mainly 
because  the  Bank  customers  had  fewer  transactions  at  non-Westamerica  ATMs  and  other  cash  dispensing  terminals.  Other 
noninterest  income  decreased  $1.8  million  primarily  due  to  the  recognition  in  2013 of  a  loan  principal  recovery  exceeding  the 
purchase date fair value. Trust fees increased $269 thousand mostly due to marketing efforts to increase customer accounts and 
higher court-approved fees. Debit card fees increased $131 thousand primarily due to higher transaction volumes. 

In 2013, noninterest income was $57.0 million, unchanged from 2012. In 2012 noninterest income included a $1.3 million loss 
realized  from  the  sale  of  a  collateralized  mortgage  obligation  bond  whose  underlying  support  tranches  began  experiencing 
escalating  losses.  In  2013,  service  charges  on  deposits  decreased  $2.0  million  or  7.2%  due  to  declines  in  fees  charged  on 
overdrawn  accounts  and  insufficient  funds  (down  $1.1  million)  and  deficit  fees  charged  on  analyzed  accounts  (down  $762 
thousand).  Merchant  processing  services  income  decreased  $703  thousand  mainly  due  to  lower  transaction  volumes.  ATM 
processing  fees  decreased  $638  thousand  primarily  because  the  Bank  customers  had  fewer  transactions  at  non-Westamerica 
ATMs  and  other  cash  dispensing  terminals.  Offsetting  these  decreases  were  higher  debit  card  fees  (up  $656  thousand)  due  to 
higher  transaction  volumes.  Additionally,  trust  fees  and  financial  services  commissions  increased  $235  thousand  and  $142 
thousand,  respectively,  from  increased  sales.  Other  noninterest  income  increased  $963  thousand  primarily  due  to  higher 
recoveries of charged off purchased loans and life insurance proceeds.

In 2014, noninterest expense decreased $5.8 million or 5.2% compared with 2013. Salaries and related benefits decreased $1.9 
million primarily due to employee attrition and lower employee benefits. Expenses for other real estate owned, net of disposition 
gains,  declined  $1.7  million  due  to  higher  net  gains  on  sale  of  repossessed  loan  collateral.  Professional  fees  declined  $711 
thousand due to lower legal fees associated with nonperforming assets. Amortization of identifiable intangibles decreased $434 
thousand as assets are amortized on a declining balance method. Other noninterest expense decreased $916 thousand primarily 
due  to  lower  loan  administration  costs  and  lower  limited  partnership  operating  losses.  Furniture  and  equipment  expenses 
increased $305 thousand primarily due to increased depreciation costs associated with computer system and software upgrades. 

Noninterest expense decreased $4.3 million or 3.7% in 2013 compared with 2012. Salaries and related benefits decreased $755 
thousand or 1.3% primarily due to employee attrition. Amortization of identifiable intangibles decreased $664 thousand as such 
assets are amortized on a declining balance method. Occupancy expense decreased $323 thousand or 2.1% mainly due to lower 
lease rates on bank premises and utility costs. Expenses relating to other real estate owned decreased $200 thousand mainly due to 
lower  writedowns.  Professional  fees  declined  $160  thousand  or  5.0%  due  to  lower  legal  fees  associated  with  nonperforming 
assets. Other noninterest expense decreased $2.0 million primarily due to lower administration expenses related to nonperforming 
loans and decreases in postage, customer check printing expenses and correspondent bank service charges. 

Provision for Income Tax

The income tax provision (FTE) was $34.2 million in 2014 compared with $37.0 million in 2013 and $44.8 million in 2012. The 
2014 effective tax rate (FTE) was 36.1% compared with 35.5% in 2013 and 35.6% in 2012. The effective tax rates without FTE 
adjustments  were  23.2%  for  2014  and  22.0%  for  2013  and  23.9%  for  2012.  The  2013  tax  provision  reflected  tax-exempt  life 
insurance proceeds and recognized California enterprise zone hiring credits for filed amended returns (2007-2009).  

On  July  11,  2013,  California’s  Governor  Jerry  Brown  signed  two  bills  which  end  a  30-year-old  enterprise  zone  tax  incentive 
program and replace it with new incentives. Due to the passage of these bills, many California tax benefits were phased out by the 
end of 2014. The Company had been realizing California tax benefits under the historical enterprise zone tax incentive program,
including: 

•

•

Exclusions of net interest income on loans funding economic activity within enterprise zones 

Tax credits realized by hiring employees within enterprise zones; however, the economic value of the tax credits is 
partially offset by a reduction in deductible compensation expense by the amount of the tax credits. 

Effective January 1, 2014, the new law eliminated the net interest deduction for enterprise zone loans and the hiring credits were 
significantly  altered.  The  Company  did  not  incur  a  significant  change  in  its  tax  provision  due  to  the  new  laws;  the  state  tax 
benefits recognized from the current enterprise zone tax incentive program for the years ended December 31, 2014 and 2013 were 
$47 thousand and $121 thousand, net of federal income tax consequences, respectively.

Investment Portfolio

The  Company  maintains  a  securities  portfolio  consisting  of  securities  issued  by  U.S.  Treasury,  U.S.  Government  sponsored 
entities, state and political subdivisions and corporations, and asset-backed and other securities. Investment securities are held in 
safekeeping by an independent custodian. 

Management has maintained relatively stable interest-earning asset volumes by increasing investment securities as loan volumes 
have declined. The carrying value of the Company’s investment securities portfolio was $2.6 billion as of December 31, 2014, an
increase of $427.8 million or 19.3% compared to December 31, 2013. 

Management  continually  evaluates  the  Company’s  investment  securities  portfolio  in  response  to  established  asset/liability 
management objectives, changing market conditions that could affect profitability, 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,  change  the  composition  of  the  Company’s  investment  securities  portfolio,  and  change  the  proportion  of 
investments allocated into the available for sale and held to maturity investment categories. 

The Company has been reducing its positions in mortgage-related securities since the second quarter 2013 in an effort to manage
extension risk.  Extension  risk  represents  the  risk  mortgages underlying the  securities  experience slower principal reductions  as
rising  market  interest  rates  cause  a  disincentive  for  borrowers  to  reduce  principal  balances;  under  such  circumstances  the 
Company will hold these securities for a longer period than anticipated at current yield levels rather than having the opportunity 
to reinvest cash flows at higher yields. The Company’s positioning of the balance sheet for rising interest rates has resulted in the 
purchase of floating rate corporate bonds, federal agency bonds, and short-term state and municipal bonds. As of December 31, 
2014, 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 issued by states, municipalities and political subdivisions 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.  Credit  ratings  are 
considered in our analysis only as a guide to the historical default rate associated with similarly-rated bonds.  There have been no 
significant differences in our internal analyses compared with the ratings assigned by the third party credit rating agencies.

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,  borrower  financial  information  including  cash  flow, 
borrower net worth and aggregate debt. 

Commercial  real  estate  loans  represent  term  loans  used  to  acquire  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. The real estate serves as collateral, secured by a first lien position on the property.  

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  three  segments.  Loans  originated  by  the  Company 
following its loan underwriting policies and procedures are separated from purchased loans. Former County Bank loans purchased

from  the  FDIC  are  segregated  as  are  former  Sonoma  Valley  Bank  loans  also  purchased  from  the  FDIC.  Loan  volumes  have 
declined due to problem loan workout activities, particularly with purchased loans, and reduced volumes of loan originations. In
Management’s opinion, current levels of competitive loan pricing do not provide adequate forward earnings potential. As a result,
the Company has not currently taken an aggressive posture relative to loan portfolio growth. 

The following table shows the composition of the loan portfolio of the Company by type of loan and type of borrower, on the

Commitments and Letters of Credit

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 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 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 established by assessing a provision for loan losses 

35

              - 35 -

against  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  Board  of  Directors.  The  Loan  Review 
Department performs independent evaluations of loans and assigns credit risk grades to evaluated loans 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”). 

The  former  County  Bank  loans  and  repossessed  loan  collateral  were  purchased  from  the  FDIC  with  indemnifying  loss-sharing 
agreements. The loss-sharing agreement on single-family residential real estate assets expires February 6, 2019. The loss-sharing
agreement on non-single-family residential real estate assets expired February 6, 2014 as to losses and expires February 6, 2017
as to loss recoveries; the Company reclassified assets for which loss indemnification expired during the first quarter 2014 from
“purchased covered” to “purchased non-covered”.

The Bank’s commercial loan customers are primarily small businesses and professionals. As a result, average loan balances are 
relatively  small,  providing  risk  diversification  within  the  overall  loan  portfolio.  At  December  31,  2014,  the  Bank’s  nonaccrual
loans  reflected  this  diversification:  nonaccrual  originated  loans  with  a  carrying  value  totaling  $5  million  comprised  eleven 
borrowers, and nonaccrual purchased loans with a carrying value totaling $12 million comprised thirteen borrowers. 

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 credit losses represents Management’s estimate of credit 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. Further, the carrying value of purchased loans includes fair value discounts assigned at 
the time of purchase under the provisions of FASB ASC 805, Business Combinations, and FASB ASC 310-30, Loans or Debt 
Securities with Deteriorated Credit Quality. The allowance for credit losses represents Management’s estimate of credit losses in 
excess of these reductions to the carrying value of loans within the loan portfolio.

The  Company's  allowance  for  credit  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
credit  loss  experience,  the  amount  of  past  due,  nonperforming  and  classified  loans,  the  amount  of  non-indemnified  purchased 
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 all loans with outstanding principal balances in excess of 
$500  thousand  which  are  classified  or  on  nonaccrual  status  and  all  “troubled  debt  restructured”  loans  for  impairment.  The 
remainder of the loan portfolio is collectively evaluated for impairment based in part on quantitative analyses of historical credit 
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 the loss emergence period. During 2014, the 
Company  refined  its  processes  used  to  measure  look-back  periods  and  loss  emergence  periods.  The  loss  rates  are  applied  to 
segmented loan balances to allocate the allowance to the segments of the loan portfolio.   

Purchased  loans  were  recorded  on  the  date  of  purchase  at  estimated  fair  value;  fair  value  discounts  include  a  component  for 
estimated credit losses. The Company evaluates all nonaccrual purchased loans with outstanding principal balances in excess of 
$500  thousand  for  impairment;  the  impaired  loan  value  is  compared  to  the  recorded  investment  in  the  loan,  which  has  been 
reduced by  the  credit  default  discount  estimated on  the  date  of  purchase.  If  Management’s  impairment  analysis  determines  the 
impaired loan value is less than the recorded investment in the purchased loan, an allocation of the allowance for credit losses is 
established for the deficiency. For all other purchased loan portfolio segments, Management applies the standard loss rates to the 
purchased  loan  portfolio  segments  to  determine  initial  allocations  of  the  allowance.  Further,  liquidating  purchased  consumer 
installment loans are evaluated separately by applying historical loss rates to forecasted liquidating principal balances to initially 
measure losses inherent in this portfolio segment. The initial allocations of the allowance to purchased loan portfolio segments are

compared  to  credit  default  discounts  ascribed  to  each  segment.  Management  establishes  allocations of  the  allowance  for  credit 
losses for any estimated deficiency. 

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, 2014 are economic and business conditions $1.7 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 $1.8 million, adequacy of lending Management and staff $1.7 million,  
concentrations of credit $3.2 million, and other factors. By their nature, these risks are not readily allocable to any specific loan 
category in a statistically meaningful manner and are difficult to quantify with a specific number. Management assigns a range of
estimated risk to the qualitative risk factors described above based on Management's judgment as to the level of risk, and assigns 
a  quantitative  risk  factor  from  the  range  of  loss  estimates  to  determine  the  appropriate  level  of  the  unallocated  portion  of  the
allowance.

Management considers the $34.2 million allowance for credit losses to be adequate as a reserve against credit losses inherent in
the loan portfolio as of December 31, 2014. 

See Note 3 to the consolidated financial statements for additional information related to the loan portfolio, loan portfolio credit
risk, and allowance for credit losses. 

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
U.S. and its agencies, particularly the Federal Reserve Board (the “FRB”).  The monetary policies of the FRB 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. 

The Federal Open Market Committee’s January 28, 2015 press release stated “To support continued progress toward maximum 
employment  and  price  stability,  the  Committee  today  reaffirmed  its  view  that  the  current  0  to  1/4  percent  target  range  for  the 
federal funds rate remains appropriate. In determining how long to maintain this target range, the Committee will assess progress 
--both realized and expected--toward its objectives of maximum employment and 2 percent inflation. This assessment will take 
into  account  a  wide  range  of  information,  including  measures  of  labor  market  conditions,  indicators  of  inflation  pressures  and 
inflation expectations, and readings on financial and international developments. Based on its current assessment, the Committee
judges that it can be patient in beginning to normalize the stance of monetary policy”  In this context, Management’s most likely
earnings  forecast  for  the  twelve  months  ending  December  31,  2015  assumes  market  interest  rates  remain  relatively  stable  and 
yields on newly originated or refinanced loans and on purchased investment securities will reflect current interest rates, which are 
generally lower than yields on the Company’s older dated loans and investment securities. 

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, 2014, 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’s interest rate risk management is currently biased toward stable interest rates in the near-
term,  and  ultimately,  rising interest  rates. 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 
can affect 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. 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 charge-offs 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  portfolio  requiring  the  Company  to  recognize  other  than  temporary 
impairment  charges.  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. 

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 97 percent of funding for average total assets in
2014 and 2013. 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. 

During 2014 and 2013, non-deposit funding has continued to be provided by short-term borrowings, a term repurchase agreement 
until  repayment  in  August  2014,  and  Federal  Home  Loan  Bank  advances,  and  additionally,  long-term  debt  until  repayment  in 
October 2013. These non-deposit sources of funds comprise a modest portion of total funding. 

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 $2.6 
billion  in  total  investment  securities  at  December  31,  2014.  Under  certain  deposit,  borrowing  and  other  arrangements,  the

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXYCompany must hold and pledge investment securities as collateral. At December 31, 2014, such collateral requirements totaled 
approximately $758 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  Federal  Home  Loan  Bank  advances,  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  will  monitor  the  Company’s  cash  levels  throughout  2015.  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, and a variety of other conditions, deposit growth may be
used to fund loans, reduce borrowings or purchase investment securities. However, due to possible concerns such as uncertainty 
in the general economic environment, 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.  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  and 
proceeds  from  the  exercise  of  stock  options  provided  adequate  cash  flow  for  the  Parent  Company  in  2014  and  2013  to  pay 
shareholder dividends of $40 million each in respective periods, and retire common stock in the amount of $53 million and $57 
million, respectively. Payment of dividends to the Parent Company by the Bank is limited under California and Federal laws. The
Company  believes  these  regulatory  dividend  restrictions  will  not  have  an  impact  on  the  Parent  Company's  ability  to  meet  its 
ongoing cash obligations.

Capital Resources

The Company has historically generated high levels of earnings, which provides a means of raising capital. The Company's net 
income as a percentage of average shareholders' equity (“return on equity” or “ROE”) has been 11.6% in 2014, 12.5% in 2013 
and 14.9% in 2012. The Company also raises capital as employees exercise stock options. Capital raised through the exercise of 
stock options totaled $12.4 million in 2014, $21.5 million in 2013 and $7.6 million in 2012.

The Company paid common dividends totaling $39.8 million in 2014, $40.1 million in 2013 and $41.0 million in 2012, which 
represent  dividends  per  common  share  of  $1.52,  $1.49  and  $1.48,  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 1.0 million shares valued at $52.7 million in 2014, 1.2 million shares valued at $57.3 million in 2013 and 
1.1 million shares valued at $51.5 million in 2012. 

The Company's primary capital resource is shareholders' equity, which was $526.6 million at December 31, 2014 compared with 
$542.9  million  at  December  31,  2013.  The  Company's  ratio  of  equity  to  total  assets  was  10.46%  at  December  31,  2014  and 
11.20% at December 31, 2013. 

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.

FDIC-indemnified assets are generally 20% risk-weighted. The FDIC indemnification expires on February 6, 2019 as to single-
family residential real estate indemnified assets and expired on February 6, 2014 as to non-single-family residential  real estate
indemnified assets. Subsequent to such dates, previously FDIC-indemnified assets will generally be included in the 100% risk-
weight category. The expiration of FDIC indemnification related to non-single-family residential real estate assets on February 6, 
2014 caused an increase in risk-weighted assets, and a corresponding decline in the Tier 1 and Total Capital ratios.  

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 would most affect the regulatory capital requirements of the Company and
the Bank: 

•
•
•
•
•

Introduce a new “Common Equity Tier 1” capital measurement,  
Establish higher minimum levels of capital,  
Introduce a “capital conservation buffer,” 
Increase the risk-weighting of certain assets, and 
Establish 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  are  subject  to  the  “advanced 
approaches rule” and intend to make the election not to include most elements of Accumulated Other Comprehensive Income in 
regulatory capital. 

Generally, banking organizations that are not subject to the “advanced approaches rule” must begin complying with the final rule
on January 1, 2015; on such date, the Company and the Bank become 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 must begin calculating standardized total risk-weighted assets on January 1,
2015. The transition period for the capital conservation buffer for all banking organizations will begin on January 1, 2016 and 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 does 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  revises  the  PCA  thresholds  to  incorporate  the  higher  minimum  levels  of  capital,  including  the  newly  proposed  “common 
equity tier 1” ratio. 

Management has evaluated the capital structure and assets for the Company and the Bank as of December 31, 2014 assuming the 
Federal  Reserve’s  final  rule  was  currently  fully  phased-in.  Based  on  this  evaluation,  the  Company  and  the  Bank  currently 
maintain capital in excess of all the final rule regulatory ratios.

The Company and the Bank intend to maintain regulatory capital in excess of the highest regulatory standard. 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.

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 2012 to 2014 the deposit composition shifted from higher costing time 
deposits  to  lower  costing  checking  and  savings  accounts.  The  Company’s  average  balances  of  checking  and  savings  accounts 
represented 90% of average balances of total deposits in 2014 compared with 86% in 2013 and 83% in 2012. 

Total time deposits were $385.1 million and $492.8 million at December 31, 2014 and 2013, respectively.  The following table

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 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, 2014. 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,  2014  based  upon  criteria  in  Internal  Control  —  Integrated  Framework  (1992)  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,  2014  based  on  the  criteria  in  Internal 
Control - Integrated Framework (1992) 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. This report is included below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders 
Westamerica Bancorporation: 

We  have  audited  Westamerica  Bancorporation  and  subsidiaries  (the  Company)  internal  control  over  financial  reporting  as  of 
December 31, 2014, based on criteria established in Internal Control – Integrated Framework (1992) issued by the Committee of 
Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  The  Company’s  management  is  responsible  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 internal control over financial reporting based on our audit.  

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control 
over financial reporting was maintained in all material respects. Our audit 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  audit  also  included  performing  such  other  procedures  as  we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.  

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

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

In  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of 
December 31, 2014, based on criteria established in Internal Control – Integrated Framework (1992) issued by the Committee of 
Sponsoring Organizations of the Treadway Commission. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated  balance  sheets  of  the  Company  as  of  December  31,  2014  and  2013,  and  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,  2014,  and  our  report  dated  February  27,  2015  expressed  an  unqualified  opinion  on  those  consolidated 
financial statements.

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  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. 

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  2015  actual  conditions  could  be  worse  than  anticipated  in  those  estimates,  which  could  materially  affect  our  results  of 
operations and financial conditions. The most significant of these involve the Allowance for Credit Losses, as discussed below 
under “Allowance for Credit Losses.” 

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 Equivalents. Cash equivalents include 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, 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 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. 

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 

55

              - 55 -                                                                

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY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  amortized  cost.  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 Home Loan Bank and 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

              - 56 -                                                                

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
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  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. 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  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 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

2014      WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXYto the respective segments of the loan portfolio. 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. 

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 an 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

              - 58 -                                                                

2014   WESTAMERICA BANCORPORATION FORM 10-K2015   WESTAMERICA BANCORPORATION PROXY 
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 Issued Accounting Standards 

FASB ASU 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and 
Disclosures,  was  issued  on  June  12,  2014.  The  Update  improves  the  financial  reporting  of  repurchase  agreements  and  other 
similar  transactions  through  a  change  in  accounting  for  repurchase-to-maturity  transactions  and  repurchase  financings,  and  the 
introduction  of  two  new  disclosure  requirements.  New  disclosures  are  required  for  (1)  transfers  accounted  for  as  sales  in 
transactions  that  are  economically  similar  to  repurchase  agreements,  in  which  the  transferor  retains  substantially  all  of  the 
exposure  to  the  economic  return  on  the  transferred  financial  asset  throughout  the  term  of  the  transaction  and  (2)  repurchase 
agreements,  securities  lending  transactions,  and  repurchase-to-maturity  transactions  accounted  for  as  secured  borrowings  about 
the nature of collateral pledged and the time to maturity of those transactions. 

The Company will be required to adhere to new disclosure requirements when the Update is adopted April 1, 2015 for the interim 
period ending June 30, 2015. 

FASB  ASU  2014-01, Investments-  Equity  Method  and  Joint  Ventures  (Topic  323):  Accounting  for  Investments  in  Qualified 
Affordable  Housing  Projects,  was  issued  January  2014  to  permit  reporting  entities  to  make  an  accounting  policy  election  to 
account  for  their  investments  in  qualified  affordable  housing  projects  using  the  proportional  amortization  method  if  certain 
conditions  are  met.  Under  the  proportional  amortization  method,  an  entity  amortizes  the  initial  cost  of  the  investment  in 
proportion  to  the  tax  credits  and  other  tax  benefits  received  and  recognizes  the  net  investment  performance  in  the  income 
statement  as  a  component  of  income  tax  expense  (benefit).  For  those  investments  in  qualified  affordable  housing  projects  not 
accounted  for  using  the  proportional  amortization  method,  the  investment  should  be  accounted  for  as  an  equity  method 
investment  or  a  cost  method  investment  in  accordance  with  GAAP.    The  policy  election  must  be  applied  consistently  to  all 
qualified affordable housing project investments. 

The  update  also  requires  a  reporting  entity  to  disclose  information  regarding  its  investments  in  qualified  affordable  housing 
projects, and the effect of the measurement of its investments in qualified affordable housing projects and the related tax credits 
on its financial position and results of operations. 

Management  has  evaluated  the  impact  that  the  change  in  accounting  policy  and  has  elected  to  not  implement  the  proportional 
amortization method. Therefore, the impact will be limited to additional disclosures only.

Expected maturities of mortgage-backed 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-backed  securities.  At  December  31,  2014  and  December  31,  2013,  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 ratings agencies, changes in the financial condition of the issuer, and, for mortgage-related 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, 2014. 

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.

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 the Board of Directors. The Loan Review Department performs  independent evaluations of loans and assigns credit 
risk grades to 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 the Loan Review Department are subject to review by the Bank’s
regulatory authorities during regulatory examinations. 

The following summarizes the credit risk profile by internally assigned grade:

ended December 31, 2012, the Company modified three loans with carrying values totaling $5,821 thousand that were considered 
troubled debt restructurings. The concessions granted in the restructurings completed in 2012 largely consisted of modifications
of payment terms extending maturity dates to allow for deferred principal repayment.  

During the year ended December 31, 2014, no troubled debt restructured loans defaulted. During the year ended December 31, 
2013 a commercial real estate loan with a carrying value of $3,954 thousand defaulted within 12 months of the modification date.
During  the  year  ended  December  31,  2012,  troubled  debt  restructured  construction  and  commercial  loans  with  carrying  values 
totaling $3,068 thousand and $988 thousand, respectively, defaulted. A troubled debt restructuring is considered to be in default 
when payments are 90 days or more past due. 

The  Company  pledges  loans  to  secure borrowings  from  the  Federal Home  Loan  Bank  of  San  Francisco (FHLB).  The  carrying 
value  of  the  FHLB  advances  was  $20,015  thousand  and  $20,577  thousand  at  December  31,  2014  and  December  31,  2013, 
respectively.  The  loans  restricted  due  to  collateral  requirements  approximated  $18,366  thousand  and  $24,242  thousand  at 
December 31, 2014 and December 31, 2013, respectively. The FHLB does not have the right to sell or repledge such loans. 

There were no loans held for sale at December 31, 2014 and December 31, 2013.  

Note 4: Concentration of Credit Risk

The  Company’s  business  activity  is  with  customers  in  Northern  and  Central  California.  The  loan  portfolio  is  well  diversified 
within  the  Company’s  geographic  market,  although  the  Company  has  significant  credit  arrangements  that  are  secured  by  real 
estate  collateral.  In  addition  to  real  estate  loans  outstanding  as  disclosed  in  Note  3,  the  Company  had  loan  commitments  and 
standby  letters  of  credit  related  to  real  estate  loans  of  $66,086  thousand  and  $62,277  thousand  at  December  31,  2014  and 
December 31, 2013, respectively. The Company requires collateral on all real estate loans with loan-to-value ratios at origination 
generally no greater than 75% on commercial real estate loans and no greater than 80% on residential real estate loans. Under the
California Financial Code, loans to any one person owing to a commercial bank at any one time shall not exceed the following 
limitations:  (a)  unsecured  loans  shall  not  exceed  15  percent  of  the  sum  of  the  shareholders'  equity,  allowance  for  loan  losses,
capital notes, and debentures of the bank, or (b) secured and unsecured loans in all shall not exceed 25 percent of the sum of the 
shareholders' equity, allowance for loan losses, capital notes, and debentures of the bank. At December 31, 2014, Westamerica 
Bank  did  not  have  loans  to  any  one  customer  exceeding  these  limits;  Westamerica  Bank  had  36  borrower  relationships  with 
aggregate loans exceeding $5 million.

Francisco (FRB) in a sum equal to six percent of the bank’s paid-up capital stock and surplus. One-half of the amount of the bank's subscription 
shall be paid to the FRB and the remaining half will be subject to call when deemed necessary by the Board of Governors of the Federal Reserve 
System.

advances. The requirement may be adjusted from time to time by the FHLB within limits established in the FHLB's Capital Plan.

Note 6: Goodwill and Identifiable Intangible Assets

The Company has recorded goodwill and other identifiable intangibles associated with purchase business combinations. Goodwill 
is not amortized, but is periodically evaluated for impairment. The Company did not recognize impairment during the years ended
December 31, 2014 and December 31, 2013. Identifiable intangibles are amortized to their estimated residual values over their 
expected  useful  lives.  Such  lives  and  residual  values  are  also  periodically  reassessed  to  determine  if  any  amortization  period 
adjustments are indicated. During the years ended December 31, 2014 and year ended December 31, 2013, no such adjustments 
were recorded.

Demand deposit overdrafts of $3,173 thousand and $3,002 thousand were included as loan balances at December 31, 2014 and 
December 31, 2013, respectively. Interest expense for aggregate time deposits with individual account balances in excess of $100
thousand was $893 thousand in 2014, $1,096 thousand in 2013 and $1,530 thousand in 2012.  

Short-term  borrowed  funds  of  $89,784  thousand  and  $62,668  thousand  at  December  31,  2014  and  December  31,  2013, 
respectively, represent securities sold under agreements to repurchase the securities. As the Company is obligated to repurchase
the  securities,  the  transfer  of  the  securities  is  accounted  for  as  a  secured  borrowing  rather  than  a  sale.  Securities  sold  under
repurchase  agreements  are  held  in  the  custody  of  independent  securities  brokers.  The  carrying  amount  of  the  securities 
approximates $148,014 thousand and $113,902 thousand at December 31, 2014 and December 31, 2013, respectively. The short-
term borrowed funds mature on an overnight basis. 

Federal  Home  Loan  Bank  (“FHLB”)  advances  with  a  carrying  value  of  $20,015  thousand  at  December  31,  2014  and  $20,577 
thousand at December 31, 2013 are secured by residential real estate loans and securities. The amount of such loans and securities 
approximates $26,484 thousand at December 31, 2014 and $32,953 thousand at December 31, 2013. The FHLB advances are due 
in full at par value upon their maturity dates: $20,000 thousand mature in January 2015. The FHLB advances may be paid off 
prior to such maturity dates subject to prepayment fees. 

The term repurchase agreement matured and was repaid in full in August 2014. At December 31, 2013, the carrying value of the 
term repurchase agreement was $10,000 thousand, representing securities sold under an agreement to repurchase the securities. 
The  Company  accounted  for  the  transfer  of  the  securities  as  a  secured  borrowing  rather  than  a  sale  due  to  its  obligation  to 
repurchase  the  securities.  At  December  31,  2013,  the  carrying  amount  of  the  related  securities  was  approximately  $11,278 
thousand, which were held in the custody of independent securities brokers. 

The  Company  has  a  $35,000  thousand  unsecured  line  of  credit  which  had  no  outstanding  balance  at  December  31,  2014  and 
December 31, 2013. The line of credit has a variable interest rate, which was 2.0% per annum at December 31, 2014, with interest
payable monthly on outstanding advances. Advances may be made up to the unused credit limit through March 18, 2015.

Note 8: Shareholders’ Equity

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

The following table summarizes information about stock options granted under the Plan as of December 31, 2014. The intrinsic 
value is calculated as the difference between the market value as of December 31, 2014 and the exercise price of the shares. The
market value as of December 31, 2014 was $48.96 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, 2014,  2013  and 2012,  the  Company  granted 294  thousand, 322  thousand  and 296  thousand  stock 
options, respectively. The following weighted average assumptions were used in the option pricing to value stock options granted
in the periods indicated:

The  Company  repurchases  and  retires  its  common  stock  in  accordance  with  Board  of  Directors  approved  share  repurchase 
programs. At December 31, 2014, approximately 1,733 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, 2014, no shares of Class B Common Stock or Preferred Stock were outstanding. 

Note 9: Risk-Based Capital 

The  Company  and  the  Bank  are  subject  to  various  regulatory  capital  adequacy  requirements  administered  by  federal  and  state 
agencies.  The  Federal  Deposit  Insurance  Corporation  Improvement  Act  of  1991  (“FDICIA”)  required  that  regulatory  agencies 
adopt  regulations  defining  five  capital  tiers  for  banks:  well  capitalized,  adequately  capitalized,  undercapitalized,  significantly
undercapitalized and critically undercapitalized. Failure to meet minimum capital requirements can initiate discretionary actions
by  regulators  that,  if  undertaken,  could  have  a  direct,  material  effect  on  the  Company’s  financial  statements.  Quantitative 
measures, established by the regulators to ensure capital adequacy, require that the Company and the Bank maintain minimum 
ratios of capital to risk-weighted assets. There are two categories of capital under the guidelines. Tier 1 capital includes common 
shareholders’ equity and qualifying preferred stock less goodwill, identifiable intangible assets, and other adjustments including 
the  unrealized  net  gains  and  losses,  after  taxes,  on  available  for  sale  securities.  Tier  2  capital  includes  preferred  stock  not
qualifying for Tier 1 capital, mandatory convertible debt, subordinated debt, certain unsecured senior debt and the allowance for 
loan  losses,  subject  to  limitations  within  the  guidelines.  Under  the  guidelines,  capital  is  compared  to  the  relative  risk  of  the
Company’s assets, derived from applying one of four risk weights (0%, 20%, 50% and 100%) to various categories of assets and 
unfunded  commitments  to  extend  credit,  primarily  based  on  the  credit  risk  of  the  counterparty.  The  capital  amounts  and 
classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. 

As of December 31, 2014, the Company and the Bank met all capital adequacy requirements to which they are subject.

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:

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 interest receivable and other assets in the Consolidated Balance Sheets. 

The provision for federal and state income taxes consists of amounts currently payable and amounts deferred are as follows:

The Company does not anticipate any significant increase or decrease in unrecognized tax benefits during 2015. Unrecognized tax
benefits at December 31, 2014 and 2013 include accrued interest and penalties of $93 thousand and $85 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. The tax years ended December 
31, 2014, 2013, 2012 and 2011 remain subject to examination by the Internal Revenue Service. The tax years ended December 
31,  2014,  2013,  2012,  2011,  2010  and  2009  remain  subject  to  examination  by  the  California  Franchise  Tax  Board.  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. 

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,  equity  and  federal  agency  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  mortgage-backed  securities,  corporate  securities,  asset-backed  securities,  municipal
bonds and residential collateralized mortgage obligations.  

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 is 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 and with a market to book ratio 
below  95:100.  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. 

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, it may need to transfer those assets or liabilities to another level in 
the hierarchy based on the new assumptions used. The Company recognizes these transfers at the end of the reporting period that
the transfers occur. For the years ended December 31, 2014 and December 31, 2013, there were no transfers in or out of levels 1,
2 or 3.

Assets Recorded at Fair Value on a Nonrecurring Basis

The Company may be required, from time to time, to measure certain assets at fair value on a nonrecurring basis in accordance 
with  GAAP.  These  adjustments  to  fair  value  usually  result  from  application  of  lower-of-cost  or  fair-value  accounting  of 
individual assets. For assets measured at fair value on a nonrecurring basis that were recorded in the balance sheet at December
31,  2014  and  December  31,  2013,  the  following  table  provides  the  level  of  valuation  assumptions  used  to  determine  each 
adjustment and the carrying value of the related assets at period end.

Level  2  –  Valuation  is  based  upon  independent  market  prices  or  appraised  value  of  the  collateral,  less  10%  for  selling  costs, 
generally.  Level 2 includes other real estate owned that has been measured at fair value upon transfer to foreclosed assets and
impaired loans collateralized by real property where a specific reserve has been established or a charge-off 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. 

Level 3 – Valuation is based upon estimated liquidation values of loan collateral.  The value of level 3 assets can also include a 
component  of  real  estate,  which  is  valued  as  described  for  level  2  inputs,  when  collateral  for  the  impaired  loan  includes  both 
business assets and real estate.  Level 3 includes impaired loans where a specific reserve has been established or a charge-off has 
been recorded.

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 1 and 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 
$31,485 thousand at December 31, 2014 and $31,693 thousand at December 31, 2013 and the fair value discount due to credit 
default  risk  associated  with  purchased  covered  and  purchased  non-covered  loans  of  $468  thousand  and  $9,372  thousand, 
respectively  at  December  31,  2014  and  purchased  covered  and  purchased  non-covered  loans  of  $10,933  thousand  and  $3,245 
thousand, respectively at December 31, 2013 were applied against the estimated fair values to recognize estimated future defaults
of contractual cash flows. The Company does not consider these values to be a liquidation price for the loans. 

FDIC  Indemnification  Receivable    The  fair  value  of  the  FDIC  indemnification  receivable  recorded  in  Other  Assets  was 
estimated  by  discounting  estimated  future  cash  flows  using  current  market  rates  for  financial  instruments  with  similar 
characteristics. 

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.

Federal Home Loan Bank Advances  The fair values of FHLB advances were estimated by using redemption amounts quoted 
by the Federal Home Loan Bank of San Francisco. 

Term Repurchase Agreement  The fair value of the term repurchase agreement was estimated by using interpolated yields for 
financial instruments with similar characteristics. 

The  table below  is  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  table  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. 

Note 12: Lease Commitments 

Thirty-two banking offices and a centralized administrative service center are owned and 68 facilities are leased. Substantially all 
the  leases  contain  renewal  options  and  provisions  for  rental  increases,  principally  for  cost  of  living  index.  The  Company  also 
leases certain pieces of equipment. 

Minimum future rental payments under noncancelable operating leases as of December 31, 2014 are as follows:  

2015 ...................................................................................................................  
2016 ...................................................................................................................

The  total  minimum  lease  payments  have  not  been  reduced  by  minimum  sublease  rentals  of  $3,702  thousand  due  in  the  future 
under  noncancelable  subleases.  Total  rentals  for  premises  were $8,798  thousand  in 2014,  $8,953  thousand  in  2013  and $9,252 
thousand in 2012. Total sublease rentals were $1,833 thousand in 2014, $1,852 thousand in 2013 and $1,883 thousand in 2012. 
Total  rentals  for  premises,  net  of  sublease  income,  included  in  noninterest  expense  were  $6,965  thousand  in  2014,  $7,101

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  $312,694  thousand  and  $320,934  thousand  at  December  31,  2014  and  December  31,  2013,  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 $29,002 thousand and $31,777 thousand at December 31, 2014 and December 31, 2013, respectively. The Company also 
had  commitments  for  commercial  and  similar  letters  of  credit  of  $40  thousand  at  December  31,  2014  and  $344  thousand  at 
December 31, 2013. 

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 is reasonably estimable.  

Note 14: Retirement Benefit Plans

The  Company  sponsors  a  qualified  defined  contribution  Deferred  Profit-Sharing  Plan  covering  substantially  all  of  its  salaried 
employees  with  one  or  more  years  of  service.  The  costs  charged  to  noninterest  expense  related  to  discretionary  Company 
contributions to the Deferred Profit-Sharing Plan were $1,002 thousand in 2014, $1,200 thousand in 2013 and $1,200 thousand in 
2012. 

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  $1,159  thousand  in  2014,  $1,214  thousand  in  2013  and  $1,255 
thousand in 2012. 

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, 2018. 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:

benefits  are  currently  fixed  amounts  without  provision  for  future  increases;  as  a  result,  the  assumed  annual  average  rate  of

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.  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. 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.

Note 16: Regulatory Matters 

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 2014. 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 $400,039 thousand in 2014 and $304,834 thousand in 2013, 
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.

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

The Board of Directors and Shareholders 
Westamerica Bancorporation:  

We have audited the accompanying consolidated balance sheets of Westamerica Bancorporation and subsidiaries (the Company) 
as  of  December  31,  2014  and  2013,  and  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, 2014. These consolidated
financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  these 
consolidated financial statements based on our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures
in  the  financial  statements.  An  audit  also  includes  assessing  the  accounting  principles  used  and  significant  estimates  made  by 
management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position 
of the Company as of December 31, 2014 and 2013, and the results of their operations and their cash flows for each of the years
in the three-year period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles. 

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States), 
Westamerica Bancorporation’s internal control over financial reporting as of December 31, 2014, based on criteria established in
Internal  Control  –  Integrated  Framework  (1992)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission  (COSO),  and  our  report  dated  February  27,  2015  expressed  an  unqualified  opinion  on  the  effectiveness  of  the 
Company’s internal control over financial reporting.

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, 2014. 

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,  2014  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 48 - 49, immediately preceding the financial statements.
