PROXY STATEMENT 
March 14, 2016 
___________ 

GENERAL 

The Westamerica Board  of  Directors  is  soliciting  proxies  to be  used at  the  2016  Annual  Meeting  of  Shareholders of 
Westamerica  Bancorporation  (the  “Company”),  which  will  be  held  at  11:00  a.m.  Pacific  Time,  Thursday,    April  28, 
2016, 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  14,  2016,  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 29, 2016, the record date, or hold a 
valid proxy for the meeting. In order to be admitted to the Annual Meeting, the Company reserves the right to request 
proof of ownership of Westamerica Bancorporation common stock on the record date. This can be: 

  A brokerage statement or letter from a bank or broker indicating ownership on February 29, 2016;  
  The Notice of Internet Availability of Proxy Materials; 
  A printout of proxy distribution email (if you received your materials electronically);  
  A Proxy Card; 
  A voting instruction form; or 
  A legal proxy provided by your broker, bank or nominee.  

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

Proxy Card. The Board has designated Arthur C. Latno, Jr., Ronald A. Nelson and Edward B. Sylvester to serve as 
Proxies for the Annual Meeting. As Proxies, they will vote the shares represented by proxies at the Annual Meeting. If 
you sign, date and return your Proxy Card but do not specify how to vote your shares, the Proxies will vote FOR the 
election of all of the Director nominees, FOR approval of the advisory vote on the compensation of our named executive 
officers,  FOR  ratifying  the  selection  of  independent  auditor,  and  AGAINST  the  shareholder  proposal  regarding  an 
independent  board  chairman.  The  Proxies  will  also  have  discretionary  authority  to  vote  in  accordance  with  their 
judgment  on  any  other  matter that  may  properly  come  before  the  Annual  Meeting  that  we  did  not  have  notice  of by 
January 22, 2016.

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  29,  2016,  25,400,207  shares  of  Westamerica 
Bancorporation  common  stock  were  outstanding.  We  also  count  broker  non-votes,  which  we  describe  below,  as 
shares present or represented at the Annual Meeting for the purpose of determining whether a quorum exists.  

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

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

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

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

Other Matters. Approval of any other matter considered at the Annual Meeting will require the affirmative vote of a

whether or not you plan to attend the Annual Meeting, please vote by proxy.

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

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

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

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

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

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

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

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

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 25, 2016. All other shareholders voting by  telephone or 
internet must vote by 12:01 a.m. Central Time, on April 28, 2016 to ensure that their vote is counted.   

Revocation of Proxy. Registered Holders who vote by proxy, whether by telephone, internet or mail, may revoke that 
proxy at any time before it is voted at the Annual Meeting. You may do this by: (a) signing another Proxy Card with a later 
date  and  delivering  it  to  us  prior  to  the  Annual  Meeting  or  sending  a  notice  of  revocation  to  the  Corporate  Secretary  of 
Westamerica at 1108 Fifth Avenue, San Rafael, CA 94901; (b) voting at a later time by telephone or  on the internet 
prior to 12:01 a.m. Central Time, on April 28, 2016 (prior to 11:59 p.m. Central Time, on April 25, 2016 for ESOP 
participants); or (c) attending the annual Meeting in person and casting a ballot. If you are a beneficial holder, you 
may change your vote by submitting new voting instructions to your broker or other nominee.  

Additional Information 

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

Section 16(a) Beneficial Ownership Reporting Compliance 

Section 16(a) of the Securities and Exchange Act requires the Company’s directors and executive officers and persons 
who  own  more  than  ten  percent  (10%)  of  a  registered  class  of  the  Company’s  equity  securities  to  file  reports  of 
ownership and changes in ownership with the Securities and Exchange Commission. Our employees generally prepare 
these reports on the basis of information received from each director and officer. Based on the review of copies of the 
forms filed, the Company believes that, during the last fiscal year, all filing requirements under Section 16(a) applicable 
to its directors, officers, and 10% stockholders were timely, except for a report by Mr. Rizzardi with respect to the sale of 
66 shares, for a voluntary distribution from his retirement account. With the Company’s assistance, the report was filed 
in the month following the distribution.  

PROPOSAL 1 – ELECTION OF DIRECTORS 

Board of Directors 
Nine Directors have been nominated for election at the Annual Meeting to hold office until the next Annual Meeting or

consented to serve a new term. The Board does not anticipate that any of the nominees will be unavailable to serve as a 
Director, but if that should occur before the Annual Meeting, the Board reserves the right to substitute another person 
as nominee. The Proxies will vote for any substitute nominated by the Board of Directors. The Proxies may use their 
discretion to cumulate votes for election of Directors and cast all of such votes for any one or more of the nominees, to 
the exclusion of the others, and in such order of preference as they may determine at their discretion. 

Nominees 
The  nominees  for  election  as  Directors  are  named  and  certain  information  with  respect  to  them  is  given  below.  Our

non-profit,  and  other  business  experience.  As  a  group  they  possess  experience  in  leadership,  consumer  banking, 
commercial and small business banking, investment banking, capital markets, financial advisory  services,  finance and 
accounting, risk management and real estate. Many of the Board Members have seen the company through a variety of 
economic conditions which was especially beneficial during the current economic environment. The information below 
has  been  furnished  to  the  Company  by  the  respective  nominees.  All  of  the  nominees  have  engaged  in  their  indicated 
principal  occupation  for  more  than  five  years,  unless  otherwise  indicated  and  no  nominee  has  served  on  the  Board  of

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

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

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

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

the independent Directors; 

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

communication.

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

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

Role of the Board of Directors in Risk Oversight 
The  Board  is  also  responsible  for  overseeing  all  aspects  of  management  of  the  Company,  including  risk  oversight, 
which is effected through all Board committees, but primarily through the Board’s Audit Committee.  The Internal Audit 
Department  reports  directly  to  the  Board’s  Audit  Committee.  It  presents  its  independently  prepared  company-wide 
annual risk assessment, its evaluation of Management’s prepared risk assessment and its audit plan incorporating the risk 
assessment, including the policies and procedures utilized to monitor and control such exposures, to the Board’s Audit 
Committee.  

The internal loan review function reports directly to the Board’s 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, to the Board’s Loan and Investment Committee. 

Meetings 
The  Company  expects  all  Board  members  to  attend  all  meetings,  including  the  Annual  Meeting  of  Shareholders, 
except for reasons of health or special circumstances. The Board held a total of ten meetings during 2015. Every Director 
attended at least 75%, with the exception of Mr. Latno who attended 60% due to health reasons, of the aggregate of: (i) 
the Board meetings held during that period in which they served; and (ii) the total number of meetings of any Committee of 
the Board on which the Director served. Each individual who served on the Board of the Company on the date of the 2015 
Annual Meeting of Shareholders attended the meeting, except for Mr. Latno.

Audit Committee 

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

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

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

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

  an understanding of internal control over financial reporting; and  
  an understanding of Audit Committee functions. 

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

Functions:  The  Audit  Committee  provides  independent,  objective  oversight  of  the  integrity  of  the  Company’s 
financial  statements,  the  Company’s  compliance  with  legal  and  regulatory  requirements,  the  independence  and 
performance of the Company’s independent auditor as it performs audit, review or attest services, and the Company’s 
internal audit and control function. It selects and retains the independent registered public accounting firm, and reviews 
the plan and the results of the auditing engagement. It acts pursuant to a written charter that was reaffirmed by the Board 
of  Directors  in  April  2015  and  is  attached  as  Exhibit  A  to  the  Proxy  Statement  for  this  2016  Annual  Meeting  of 
Shareholders. 

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

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

Committee  also  establishes  the  individual  goals  and  targets  for  the  CEO.  All  compensation  approved  by  the 
Compensation  Committee  is  reported  to  the  full  Board  of  Directors.  The  role  of  the  Compensation  Committee  is 
described in greater detail under the section entitled “Compensation Discussion and Analysis.” 

The Compensation Committee is governed by a written charter as  required by NASDAQ rules.  The charter was 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 Company as well as 
external legal, accounting and other advisors. It has not retained outside consultants for compensation advice, but can 
request  assistance  on  an  as-needed  basis.  It  does  not  delegate  authority  to  anyone  outside  of  the  Compensation 
Committee. The Payroll and Employee Benefits Department supports the Compensation Committee by fulfilling certain 
administrative duties regarding the compensation programs. 

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

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

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 the Company. In addition 
to  the  qualifications  and  characteristics  described  below,  it  considers  whether  the  potential  Director  assists  in 
achieving  a  mix  of  Board  members  that  represents  a  diversity  of  background,  perspective,  and  experience.  Our 
Board  includes  Directors  with  experience  in  public  corporations  and  non-profit  organizations,  as  well  as 
entrepreneurial individuals who have  successfully run their own private enterprise. Our Board also has a broad set of 
skills  necessary  for  providing  oversight  to  a  financial  institution,  which  includes  proven  leadership,  and  expertise  in 
capital management, finance, accounting, regulatory affairs, and investment management. 

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

held, the Company must receive notice with a reasonable amount of time before the Company mails its proxy materials 
for the current year. 

Nominations must include the following information: 
  The principal occupation of the nominee; 
  The total number of shares of capital stock of the Company that the shareholder expects will be voted for the 

nominee; 

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

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

  Appropriate personal and professional attributes to meet the Company’s needs; 
  Highest ethical standards and absolute personal integrity; 
  Physical and mental ability to contribute effectively as a Director; 
  Willingness and ability to participate actively in Board activities and deliberations; 
  Ability to approach problems objectively, rationally and realistically; 
  Ability to respond well and to function under pressure;

each Annual Meeting of Shareholders since 2010, a majority of our shareholders approved an advisory proposal on 
the Company’s executive compensation. 

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

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

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

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

is rated “threshold” or better. The purpose of long-term incentive grants is to: 
–  motivate senior management to focus on long-term performance; 
–  avoid excessive risk-taking and instill conservative management practices; 
–  build equity ownership among Westamerica’s senior management; 
– 
link shareholder interests to management incentives; and 
–  create ownership mentality among senior management.   

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

Establishing Incentive Levels, Determining Objectives and Measuring Performance 
In administering the executive compensation program, the Compensation Committee determines “target”  incentives 
for each position annually. The Compensation Committee exercises discretion in establishing “target”  incentives in an 
effort to provide competitive pay practices while motivating and rewarding performance that benefits the Company’s long-term 
financial performance and shareholder interests, and 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  Company  and  its  shareholders.  Corporate 
performance measures include risk management elements considered to be responsive to the impact that current operating 
conditions  could  have  on  the  long-term  performance  of  the  Company.  The  Compensation  Committee  monitors  the 
economy and  the banking  industry’s operating  environment  throughout the  ensuing year, and may exercise discretion in 
adjusting corporate performance objectives during the year. 

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

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

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

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

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

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

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

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

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

extend the term or approve a new stock option plan. 

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

Incentive Stock Options (“ISO”) allow the optionee to buy a certain number of shares of Westamerica Bancorporation 
common  stock  at  a  fixed  price,  which  is  established  on  the  date  of  the  option  grant.  ISOs  are  intended  to  meet  the 
requirements of Section 422 of the Internal Revenue Code which provide advantages if certain conditions are met. If the 
optionee holds the acquired stock for the designated holding period, the optionee defers the timing of recognizing 
taxable income related to exercising the ISO. If the optionee complies with the ISO requirements, the Company does

not receive a corporate tax deduction related to the shares issued. 

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

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

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

Determination of Awards to Grant 

In  determining  which  type  of stock-based  compensation  awards  to  grant, the  Compensation  Committee  considers  the 
attributes of each form of incentive. Examples include the ability to motivate management to make decisions based on 
the long-term interests of shareholders, the desire to compensate with shares rather than cash, and the tax consequences of 
each type of award. The Compensation Committee retains the latitude to utilize all forms of  incentives  provided  under  the 
2012 Amended Plan. In the current and preceding years, the Compensation Committee has utilized NQSO and RPS 
based  on  the  motivational  aspects  of  stock  price  appreciation,  the  settlement  in  shares  rather  than  cash,  and  the 
preservation of tax deductions for the Company. As of February 29, 2016, the Company had no ISO or SAR awards 
outstanding. 

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

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

(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.

this responsibility, the Compensation Committee designs such awards as long-term incentives. The terms and conditions 
of currently outstanding awards include: 

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

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

Compensation for the Chairman, President & CEO 
Mr. Payne performs two functions for the Company. These two functions tend to be compensated separately at similarly 
sized banking institutions. Mr. Payne serves as Chairman of the Board and 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  27  of  the  Proxy  under  the  Pension  Benefits  Table,  during  1997  the  Company  entered  into  a 
nonqualified pension agreement (“Pension Agreement”) with Mr. Payne in consideration of Mr. Payne’s agreement that 
RPS  granted  in  1995,  1996  and  1997  would  be  cancelled.(2)  In  entering  the  Pension  Agreement,  the  Board  of 
Directors considered the following: 

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

  In  1997,  the  Company  had  consummated  its  largest  acquisition,  with  significant  total  asset  growth  of 
approximately 51 percent. One of the Board’s objectives was to provide a compensation mechanism providing retention 

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

Compensation Awarded to Named Executive Officers 

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

"Target"
Cash
Incentive

X

Composite Corporate,
Divisional and Individual
Performance Level

In  structuring  performance  goals  for  the  named  executive  officers,  the  Compensation  Committee  emphasizes  goals, 
which  if  achieved,  will  benefit  the  overall  Company.  As  such,  senior  management  level  positions  have  high  relative 
weighting  on  corporate  objectives,  and  divisional  leadership  positions  also  have  significant  weighting  on  divisional 

(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 Company and its future earnings potential. The 2015 corporate performance goals related to current year 
“profitability” included return on equity, return on assets and diluted earnings per share. The performance goals designed 
to maintain the long-term stability of the Company include “quality” and “control” components. The “quality” measures 
include  loan  portfolio  quality  measures  (originated  classified  loans  and  other  real  estate  owned,  originated  non-
performing loans and originated other real estate owned, and net loan losses to average originated loans) and service 
quality  measures  (external  service  quality  to  customers  and  internal  service  quality  of  support  departments  and 
branches). The “control” measures include non-interest expense to revenues (efficiency ratio), the level of non-interest 
expenses, and internal audit results. By maintaining both current year “profitability” goals and longer-term “quality” 
and “control” goals, Management has a disincentive to maximize current earnings at the expense of longer-term results.  

For 2015, the Compensation Committee expected nominal economic growth within the markets the Corporation 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 2015 operating environment was generally characterized as follows: 
  Growth in the United States’ gross domestic product was positive, but generally below potential; 
  Inflation remained below targets established by the Federal Open Market Committee in spite of continuing high 

levels of monetary policy accommodation; 

  Interest rates remained low; 
  Employment trends continued to improve; 
  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 portfolio throughout 2015; 
  Competitive pricing of loans was aggressive; 
  Regulations  imposed on  financial  institutions  continued  to  pressure  compliance  costs,  revenue  opportunities, 

and operational risks; and 

  Credit risk in the banking industry continued to improve. 

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

  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 and shortened the duration of the securities 

portfolio to prepare for rising interest rates on a forward basis; 

  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 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; 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 110.8% 
of target goals. 

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

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

  Maintaining prudent credit underwriting and pricing practices within the current operating environment; 
  Avoiding duration extension in the loan and investment portfolios to position the Company for a rising interest 

rate environment; 

  Credit quality improvement; 
  Satisfactory regulatory examination results; 
  Achievement of financial goals; 
  Managing operating expenses to lower levels; 
  Maintaining appropriate internal controls and risk management practices; 
  Effective leadership and management through divisional managers and other points of control; 
  Pursuing mergers and acquisitions; 
  Completing routine visits to branches and credit underwriting offices; 
  Conducting quality shareholder relations activities; and 
  Maintaining quality customer relations activities. 

Based on individual performance against these goals, the Committee exercised its discretion and assigned Mr. Payne 
a composite corporate and individual performance level of 61%.

RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved over 
the  three-year  period.  In  January  2016,  the  Compensation  Committee  evaluated  whether  the  three  year  corporate 
performance  objectives  were  met  for  RPS  awards  granted  in  January  2013.  The  performance  objectives  for  the  RPS 
granted in January 2013 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. 

The goals and achieved results were:

the ability to defer compensation in excess of the annual limits imposed on the Company’s “401(k)” plan. The Company

believes  these  tax  deferral  programs  enhance  loyalty  and  motivate  retention  of  executives.  These  programs  allow 
executives to defer cash pay and RPS shares upon vesting. The programs also allow Directors to defer Director fees. 

  Cash  pay  deferred  in  the  program  accumulates  in  accounts  in  the  names  of  the  participating  Directors  and 
executives.  The  Company  credits  the  balance  of  these  accounts  with  interest  using  an  interest  rate  that 
approximates  the  crediting  rate  on  corporate-owned  life  insurance  policies,  under  which  Directors  and 
executives are the named insured. Deferrals and interest credits represent general obligations of the Company. 
  The common stock the Company issues to executives upon the vesting of RPS grants may be deferred into the 
program  and  deposited  into  a  “Rabbi  Trust.”  Since  these  shares  are  outstanding  shares  of  the  Company’s 
common  stock,  the  Company  pays  dividends  on  these  shares  at  the  same  rate  paid  to  all  shareholders.  The 
shares held in the “Rabbi Trust” are subject to claims by the Company’s creditors. 

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

Compensation in the Event of a Change in Control 
The banking industry has significant merger and acquisition activity. To promote retention of senior executives, unvested 
NQSO and RPS grants contain a “change in control” provision, which trigger full vesting upon a change in control. The 

Compensation  Committee  determined  these  provisions  were  appropriate  in  order  to  retain  executives  to  continue 
managing the Company after any “change in control” was announced through its ultimate consummation. Since none of 
the named executive officers have entered employment contracts with the Company, they serve in an “at-will” capacity 
and could terminate their employment at any time. The Compensation Committee felt it would be in the best interests of 
shareholders to have a retention mechanism in place to provide continuity of management during a “change in control” 

process. Further, the Committee expects the named executive officers would be terminated by an acquiring institution 
rather than retained in a similar functional capacity. 

The Company also maintains a Severance Payment Plan covering all employees to promote employee retention. The 
Severance Payment Plan provides salary continuation benefits for employees in the event of a “change in control.” 

The amount of salary continuation benefits is based on years of service and corporate title, but in no event exceed 
the equivalent of one times annual salary. All named executive officers are eligible for  one year’s salary under the 
plan. 

Other  
Internal Revenue Code (“IRC”) Section 162(m) places a limit on the amount of compensation that may be deducted 
by the Company in any year with respect to certain of the Company’s highest-paid executives. Certain “performance-
based compensation” is not counted toward this limit. The Company 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. 

Employee Benefits Compensation Committee Report 

We,  the  Compensation  Committee  of  the  Board  of  Directors  of  the  Company,  have  reviewed  and  discussed  the 
Compensation Discussion and Analysis with Management. Based on that review and discussion, we have recommended 
to  the  Board  of  Directors  inclusion  of  the  Compensation  Discussion  and  Analysis  in  this  Proxy  Statement  and  the 
Company’s Annual Report on Form 10-K for the year ended December 31, 2015.

Non-Qualified Pension Agreement

$5,366,778

$511,950

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

The  discount  rate  used  to  determine  the  present  value  is  4.30%,  as  used  by  the  Company  in  determining  benefit 
obligations  for  its  post-employment  retirement  benefits  as  of  December  31,  2015.  The  obligation  is  an  unfunded 
general obligation of the Company.

(2) Includes change in value of deferred RPS shares, dividends earned on deferred RPS shares, and interest earned on deferred cash compensation.  The 
amounts included in the Summary Compensation Table for  Fiscal Year  2015 on page 24 are as follows:  Messrs. Thorson - $38,786; Robinson -

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 2015 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 Company or a sale of substantially all of the Company’s assets to another company, or a tender offer for 5% 
or more of the Company’s outstanding common stock or a merger in which the Company’s shareholders before the 
merger hold less than 50% of the voting power of the surviving company after the merger. 

In  the  event  of  a  change  in  control,  unvested  NQSOs  and  RPS  shares  immediately  vest.  The  value  of  in-the-money 
options and RPS shares subject to accelerated vesting for each of the named executive officers is as follows:  Messrs. 
Payne: $0; Thorson: $507,282; Robinson: $511,202; Hansen: $457,374; and Rizzardi(3) $411,855. The value is computed 
by multiplying the difference between the market value on December 31, 2015, the last business day of 2015, and the 
exercise price of each option by the number of shares subject to accelerated vesting. 

Under the Company’s Severance Payment Plan, executive officers receive six weeks pay for every year or partial year 

(3) Mr. Rizzardi’s compensation is subject to garnishments and liens pursuant to certain domestic relations orders.

of  service  up  to  one  year’s  base  salary  (see  Summary  Compensation  Table  for  Fiscal  Year  2015  for  annual  base 
salary for all named executive officers). All named executive officers have met the service requirement for one year’s 
base  salary.  Severance  pay  is  paid  in  a  lump  sum  or  on  a  semi-monthly  basis  at  the  discretion  of  the  Company.  The 
Severance Payment Plan is subject to Section 409A of the Internal Revenue Code. 

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 Company’s Code of Conduct and Ethics provides rules that restrict transactions with 
affiliated persons.   

Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries of the 
Company  in  the  ordinary  course  of  business.  With  the  exception  of  the  Company’s  Employee  Loan  Program,  all 
outstanding loans and commitments included in such transactions were made on substantially the same terms, including 
interest rates and collateral, as those prevailing at the time for comparable transactions with other persons not related 
to the Company, did not involve more than a normal risk of collectability, and did not present other favorable features. 
As part of the Employee  Loan Program, all employees, including executive officers, are eligible to receive  mortgage 
loans  with  interest  rates  one  percent  (1%)  below  Westamerica  Bank’s  prevailing  interest  rate  at  the  time  of  loan 
origination. Westamerica Bank makes all loans to executive officers under the Employee Loan Program in compliance 
with the applicable restrictions of Section 22(h) of the Federal Reserve Act. Messrs. Payne, Thorson, and Hansen have 
mortgage loans through this Program. The largest aggregate amount of principal during 2015 was $423,287, $299,280, 
and  $234,596,  respectively.  The  principal  amount  outstanding  at  December  31,  2015  was  $404,058,  $282,451,  and 
$224,274, respectively. The amount of principal paid during 2015 was $19,229, $16,829, and $10,322, respectively. The 
amount of interest paid during 2015 was $7,985, $5,450, and $4,310, respectively. The rate of interest payable on the 
loan is 2.00%, 2.00%, and 1.875%, respectively.  

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

Background 
The  2010  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act  (the  “Dodd-Frank  Act”)  requires  that 
shareholders cast a non-binding advisory vote on the executive compensation paid to the executive officers listed in the 
Summary Compensation Table (a so-called “say on pay” vote) as well as an advisory vote with respect to whether 
future say on pay votes will be held every one, two or three years. The result of the shareholder vote on the proposal 
to  determine  the  frequency  of  future  say  on  pay  proposals  was  that  shareholders  should  review  executive 
compensation annually. Therefore, Proposal 2 requests that shareholders again approve the compensation paid to our 
named  executive  officers.  Last  year  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 provides for the grant 
of incentive stock options, non-qualified stock options, stock appreciation rights, and restricted performance shares. The 
Summary Compensation Table shows very stable base salaries indicative of our greater emphasis on performance-based 
stock  and  non-stock  awards.  Our  stock  and  option  awards  are  based  on  a  minimum  achievement  of  meeting  the 
“threshold” level for each pre-established objective. Both awards have a three-year vesting period. Our annual incentive 
plan incorporates at least four financial and/or strategic performance metrics in order to properly balance risk with the 
incentives  to  drive  our  key  annual  financial  and/or  strategic  initiatives;  in  addition,  the  annual  incentive  program 
incorporates a 150% maximum payout to further manage risk and the possibility of excessive payments.

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

  Disallowing re-pricing stock options for poor stock performance; 
  Limiting the number of shares that may be awarded; and 
  Requiring the Compensation Committee to meet the definition of independence to enable any award intended to 

qualify as “performance-based compensation” to meet Section 162(m) of the Internal Revenue Code. 

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

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

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

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

Vote Required  
The “say on pay” proposal gives you as a shareholder the opportunity to endorse or not endorse our executive pay 

program through the following resolution: 

“Resolved, that the shareholders approve, on an advisory basis, the compensation of the named executive 

officers,  as  disclosed  pursuant  to  the  compensation  disclosure  rules  of  the  Securities  and  Exchange 
Commission,  which  disclosure  includes  the  compensation  discussion  and  analysis,  the  compensation 
tables and any related footnotes and narratives in the Company’s proxy statement for the Annual Meeting 
of Shareholders.” 

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

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

PROPOSAL 3 – RATIFY SELECTION OF INDEPENDENT AUDITOR   

Change in Certified Accountant 

Dismissal of Previous Independent Accounting Firm 

On February 25, 2015, the Audit Committee of the Board of Directors of the Company, dismissed KPMG LLP as the 
Company’s principal independent accounting firm upon completion of the audit of the consolidated financial statements 

as of and for the year ended December 31, 2014. 

During the Company’s two most recent fiscal years ended December 31, 2014, there were no disagreements between the 
Company and KPMG LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing 
scope or procedures that, if not resolved to KPMG LLP’s satisfaction, would have caused it to  make reference to the 
matter in conjunction with its report on the Company’s consolidated financial statements for the relevant year, and there 

were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

The audit report of KPMG LLP on the consolidated financial statements of the Company as of December 31, 2014 and 
2013, contained  no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit 
scope or accounting principles. 

The Company furnished a copy of the above disclosure to KPMG LLP and requested that KPMG LLP provide a letter 
addressed to the U.S. Securities and Exchange Commission (SEC) stating whether or not it agrees with the statements 
made  above.  A  copy  of  the  letter  from  KPMG  LLP  dated  March  3,  2015  is  filed  as  Exhibit 16.1  to  the  Company’s 
Form 8-K filed with the SEC on March 3, 2015. 

Engagement of New Independent Accounting Firm 

On February 25, 2015, the Audit Committee of the Board of Directors of the Company approved the engagement of 
Crowe  Horwath  LLP  as  the  Company’s  independent  registered  public  accounting  firm  for  the  fiscal  year  ending 
December 31, 2015. During the Company’s two fiscal years ended December 31, 2014 and 2013 neither the Company, 
nor anyone on its behalf, consulted with Crowe regarding either (i) the application of accounting principles to a specified 
transaction,  either  completed  or  proposed;  or  the  type  of  audit  opinion  that  might  be  rendered  on  the  Company’s 

consolidated financial statements; and as such, no written report or oral advice was provided, and none was an important 
factor considered by the Company in reaching a decision as  to the accounting, auditing,  financial reporting issues; or 
(ii) or any matter that was either the subject of a disagreement or a reportable event. 

Ratify Selection of Independent Auditor 

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

Audit Fees 

The aggregate fees billed to the Company by Crowe Horwath LLP, the independent audit firm for fiscal year 2015 and 
the aggregate fees billed to the Company by KPMG LLP, the independent audit firm for fiscal year 2014, 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 Company for the purpose of preparing or issuing an audit report or performing 
other audit, review or attest services for the Company. Any accounting firm appointed by the Company reports directly 
to the Audit Committee. 

The  Audit  Committee  must  preapprove  all  auditing  services  and  permitted  non-audit  services  by  its  independent 
auditors and the fees to be paid by the Company for these services, except for those fees qualifying for the “de minimis 
exception”  which  provides  that  the  preapproval  requirement  for  certain  non-audit  services  may  be  waived  if  certain 
express standards and requirements are satisfied prior to completion of the audit under certain conditions. This exception 
requires that the aggregate amount of all such services provided constitutes no more than five percent of the total amount 
of  revenue  paid  to  the  audit  firm  by  the  Company  during  the  fiscal  year  in  which  the  services  are  provided.  This 
exception also requires that at the time of the engagement, the Company did not recognize such services to be non-audit 
services,  and  such  services  are  promptly  brought  to  the  attention  of  the  Audit  Committee  and  approved  prior  to  the 
completion of the audit by the Audit Committee. During fiscal year 2015, there were no non-audit services that were 
provided using this exception. 

The Audit Committee may delegate to one or more members of the Audit Committee the authority to grant preapprovals 
of non-audit services and fees. In such event, the decisions of the member or members of the Committee regarding 
preapprovals are presented to the full Audit Committee at its next meeting. The Audit Committee preapproved 100% 
of all services performed on behalf of the Company by Crowe Horwath LLP during fiscal year 2015.  

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

AUDIT COMMITTEE REPORT 

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

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

In performing its functions, the Audit Committee acts only in an oversight capacity and necessarily relies on the work 
and  assurances  of  the  Company’s  management,  which  has  the  primary  responsibility  for  financial  statements  and 
reports, and of the independent auditors. The auditors express an opinion on the conformity of the Company’s annual 
financial  statements  to  generally  accepted  accounting  principles.  In  fulfilling  its  oversight  responsibilities,  the  Audit 
Committee  reviewed  the  audited  consolidated  financial  statements  for  the  fiscal  year  2015  and  discussed  them  with 
Management and with Crowe Horwath, LLP, the Corporation’s independent auditors. 

Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in 
accordance with generally accepted accounting principles. Management also represented that it performed an assessment 
of the effectiveness of internal control over financial reporting as of December 31, 2015, and that internal control over 
financial reporting was effective. The independent auditor discussed with the  Audit Committee matters required to be 
discussed by Auditing Standard No. 16 (Communications with Audit Committees), including certain matters related to 
the conduct of an audit and to obtain certain information from the Audit Committee relevant to the audit.

The auditors also provided to the Audit Committee the written disclosures and the letter from the independent auditors 
required by 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 Company’s Annual Report on Form 10-K for the year ended December 31, 2015 for filing with the SEC.

PROPOSAL 4 – REQUIRE INDEPENDENT BOARD CHAIRMAN  

The Board unanimously recommends you vote “AGAINST” the shareholder proposal set forth below. 

Shareholder Proposal 

Gerald R. Armstrong, 621 Seventeenth Street, No. 2000, Denver, Colorado 80293-2001, (303) 355-1199, the owner of 
3,455  shares  of  our  common  stock,  has  advised  us  that  he  plans  to  introduce  the  following  resolution  at  the  annual 
meeting. In accordance with rules of the SEC, the text of the proponent’s resolution and supporting statement is printed 
verbatim from his submission. 
That the shareholder of Westamerica Bancorporation request its Board of Directors to adopt a policy and amend the 
by-laws as necessary, to require the Chairman of the Board of Directors be an independent member of the Board of 
Directors. 
This policy should not be implemented to violate any contractual obligation and should specify: (a) how to select a 
new  ‘‘independent’’  chairman  if  the  current  chairman  ceases  to  be  independent  during  the  time  between  annual 
meetings of shareholders; and, (b) that compliance is excused if no independent director is available and willing to 
serve as Chairman. 
The reasons given by the proponent for the resolution are as follows: 
This proposal’s proponent is a long-term shareholder of Westamerica Bancorporation owning shares since 1989 and 
owned shares in most of the banks acquired by Westamerica. 
As a shareholder, I am concerned about the wilting performance of Westamerica which, after analysis, I believe to 
be caused by the entrenchment of David Payne as Chairman, Executive Officer, and President and members of the 
Board  of  Directors  whose  average  tenure  was  27.5  years  and  an  average  age  of  75  years  (based  on  the  proxy 
statement for the 2015 annual meeting). 
Let’s  look  at  some  numbers  of  the  “Five  Year  Return  Performance”  graphs  contained  in  10-K  reports  of 
Westamerica  and  two  other  bank  holding  companies.  (Cumulative  Return  on  investment  and  re-investment  of  all 
dividends): 

Westamerica Bancorporation 
Bank of Marin Bancorp 
FNB Bancorp (South San Francisco) 

12/31/2009 
$   100.00 
     100.00 
     100.00 

12/31/2014 
$   103.08 
     177.00 
     495.04 

The greatest difference in the governance practices of Bank of Marin Bancorp and FNB Bancorp is that each has an 
“independent chairman” of the Board of Directors while Westamerica has one person, David Payne, serving in both 

capacities. In other words, he, as President accounts to himself as Chairman. I believe that this is why Westamerica

is the underachiever. 
Moreover, I believe Mr. Payne’s dual positions at Westamerica are only part-time as the proxy statement discloses 
he “also manages his family printing, publishing and cable television business.” 
DuPont’s failures were placed upon its Board Chair and Chief Executive Officer who was ousted by its board in the 
same manner that Target Company’s board ousted its Chairman/Chief Executive Officer a year earlier. Studies have 
confirmed that underperforming companies lack an independent chairman and companies, worldwide, are routinely 
separating  the  positions  of  Chairman  and  CEO  (CEO  Succession  2000-2009:  A  Decade  of  Convergence  and 
Compression, Booz & Co., Summer, 2010). 
A  2007  Booz  &  Co.  study  found  that  in  2006,  all  of  the  underperforming  North  American  companies  with  long-
tenured CEO’s lacked an independent Chairman (The ERA of the Inclusive Leader; Summer, 2007). 
Norges Bank Investment Management, has stated in support of a similar proposal:   
‘‘The  roles  of  Chairman  of  the  Board  and  CEO  are  fundamentally  different  and  should  not  be  held  by  the  same 

person. There should be a clear division of responsibilities between these positions to insure a balance of power and 
authority on the Board.” 
If you agree, please vote ‘‘FOR’’ this proposal.  

Board of Directors’ Recommendation 
The proposal's comparison of Westamerica’s stock performance to two peers is misleading in regard to stock 
performance and Westamerica’s leadership. 
The five-year stock performance evaluation provided in the shareholder’s proposal begins with December 31, 2009, 
a  point  in  time  when  publicly  traded  bank  stock  values  reflected  significant  declines  due  to  the  “Financial 
Recession”  of  2008  and  2009.  Contrary  to  the  banking  industry’s  negative  stock  performance  as  a  result  of  the 
recession, Westamerica’s stock price rose in 2008 and 2009, as depicted in the ten-year performance chart on page 
15  of  the  enclosed  Form  10-K,  Annual  Report.  During  this  period,  shareholders  recognized  the  value  of 
Westamerica’s leadership and its conservative, value-oriented, and long-term strategies. Westamerica’s exceptional 
credit quality and strong financial condition leading into the recession positioned the Company to grow by acquiring 
two failed banks from the FDIC.  
Westamerica’s current leadership was established in 1989, coincidentally the same  year the proposing shareholder 
became an investor in Westamerica Bancorporation common stock. The company’s current leadership has  followed 
consistent  low-risk  value-oriented  strategies  which  have  provided  superior  long-term  stock  performance  through 
three business cycles: 

Total Return with Dividends Reinvested December 29, 1989 through December 31, 2015(4) 

Westamerica Bancorporation (WABC) 
S&P 500 Index (SPX) 
NASDAQ Bank Index (CBNK) 

1,039% 
   902% 
   630% 

Westamerica’s shareholders are best served by our current leadership structure.  
In  light  of  the  current  environment  for  the  banking  industry  and  Westamerica’s  business  strategies,  the  Board 
believes that the most effective leadership structure for Westamerica at the present time is for our CEO, David L. 
Payne, to serve as chairman of the Board. Combining the positions of chairman and CEO most effectively utilizes 
Mr. Payne’s extensive experience and knowledge regarding our company. Chairman Payne was appointed CEO in 
1989  and  since  his  appointment  identified,  negotiated  and  executed  eleven  acquisitions  to  fuel  Westamerica’s 

growth. Each of the acquisitions resulted in higher levels of earnings per share within one or two quarters following 
the  acquisition.  Mr.  Payne  has  the  knowledge,  expertise  and  experience  to  continue  implementing  Westamerica’s 

long-term strategies. 
The Board believes that Mr. Payne has the requisite talent, foresight, and leadership skills to perform at a high-level

in the roles of CEO and chairman. By combining the positions, the Board can respond quickly and effectively to the 
many business, market and regulatory challenges facing banks in the rapidly changing banking industry. 

The Board should retain the flexibility to determine the most effective leadership structure for Westamerica.  
The  Board's  leadership  structure  should  be  determined  in  light  of  all  relevant  facts  and  circumstances  at  a  given 
time.  This  approach  allows  the  Board  flexibility  to  determine  whether  the  roles  of  CEO  and  chairman  should  be 
separate  or  combined  based  upon  Westamerica’s  needs  and  the  Board's  assessment  of  our  company's  leadership 

from time to time. The Board has deep knowledge of our strategic goals and the various strengths and capabilities of 
our senior management. Thus, the Board is best positioned to determine the most effective leadership structure for 
Westamerica at any given time.  

Westamerica’s  corporate  governance  practices  provide  for  strong  independent  leadership  and  effective 

independent oversight of our company.  
The  Board  is  committed  to  maintaining  high  corporate  governance  standards,  and  has  implemented  a  structure  to 
provide for Board independence and effective oversight of management. With the exception of Mr. Payne, the Board 
is  composed  entirely  of  independent  directors,  and  key  committees  are  fully  comprised  of  independent  directors. 
Further,  in  accordance  with  widely  accepted  corporate  governance  guidelines,  the  Board  has  established  a  strong, 
independent  lead  director  who  must  serve  at  least  one  year  and  has  the  following  clearly  delineated  and 
comprehensive duties: 

  Presides at all meetings of the board at which the chairman is not present, including executive sessions of 

the independent directors; 

  Serves as liaison between the chairman and the independent directors; 
  Approves information sent to the Board; 
  Approves meeting agendas for the Board; 
  Approves meeting schedules to assure that there is sufficient time for discussion of all agenda items; 
  Has the authority to call meetings of the independent directors; and 
 

If  requested  by  major  shareholders,  ensures  that  he  or  she  is  available  for  consultation  and  direct 
communication.

EXHIBIT A 
Westamerica Bancorporation 
Audit Committee Charter – Reaffirmed April, 2015 

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, statement of income and comprehensive income, statement of changes in shareholders’ 
equity and statement of cash flows and at least one member must have the additional financial sophistication as required 
by and as defined in Nasdaq rules. 

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

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

The  Audit  Committee  shall  have  the  authority  to  retain  independent  legal,  accounting  or  other  advisors  as  it  deems 
necessary  to  carry  out  its  duties.    The  Company  shall  provide  for  appropriate  funding,  as  determined  by  the  Audit

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.

(a)  an overview of the overall audit strategy, particularly the timing of the audit, significant risks the auditor

11.  Discuss, prior to release by the Company, the earnings press releases (paying particular attention to any use of 
“pro  forma,”  or  “adjusted”  or  other  non-GAAP  information)  as  well  as  financial  information  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 the selective disclosure of material information).

internal controls or material weaknesses therein and any fraud involving 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 Company. 

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  services  is  compatible  with 
maintaining the auditor’s independence.  The opinions of management 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  independent 
auditor’s independence and discuss such reports with the auditor.  Ensure that each independent auditor submits 

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

21.  Obtain and review a report from each independent auditor at least annually regarding the independent auditor’s 
internal quality control procedures.  The report should include any  material issues 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. 

Compliance Oversight Responsibilities 

30.  Obtain  reports  from  management  and  the  Company’s  senior  internal  auditing  executive  that  the  Company’s 
subsidiary  affiliated  entities  are  in  conformity  with  applicable  regulatory  and  legal  requirements  and  the

31.  Advise  the  Board  with  respect  to  the  Company’s  compliance  with  the  Company’s  Code  of  Ethics  for  Chief 

Executive Officer and Senior Financial Officers. 

32.  Establish procedures for the receipt, retention and treatment of complaints received by the Company regarding 
accounting, internal accounting controls or auditing  matters, and the confidential, anonymous submission by 
employees of concerns regarding questionable accounting or auditing matters. 

33.  Discuss with management and each independent auditor any correspondence with regulators or governmental 
agencies and any published reports that raise material issues regarding the Company’s financial statements or 
accounting policies. 

34.  Review  with  appropriate  members  of  management  or  appropriate  legal  counsel  the  Company’s  compliance 
policies, legal matters that may have a material impact on the financial statements and any material reports or 
inquiries received from regulators or governmental agencies.

Regulation S-K for potential conflicts of interests.   

36.  In the event the Audit Committee is made aware of any allegation of fraud relating to the Company and/or any 
of  its  officers,  directors or  employees  that  the  Audit  Committee  deems  could  be  material  to  the  Company’s 

business or operations, the Audit Committee shall (i) convene a meeting of the Audit Committee to review such 
allegation and (ii) if the Audit Committee deems it necessary or advisable, it shall engage independent counsel 
to assist in an investigation, including, if the Audit Committee and such counsel deem it necessary or advisable, 
an investigation to determine whether such allegation implicates any violation of Section 10A of the Exchange 
Act  of  1934.    If  pursuant  to  such  investigation  the  Audit  Committee  discovers  that  a  material  fraud  has 
occurred, the Audit Committee shall (i) assess the Company’s internal controls and implement such remedial 
measures as it determines necessary or advisable, (ii) cause the Company to take appropriate action against the

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

with each of the Company’s CEO, senior internal audit executive and the  independent auditor; and each such 

person shall have free and direct access to the Audit Committee and any of its members. 

39.  Review and approve all related-party transactions (e.g. transactions with any director or executive officer of the 
Company or significant shareholder, or their immediate family members or affiliates), other than transactions 
which  the  Board  has  delegated  to  the  Company’s  Employee  Benefits/Compensation  Committee  or  Loan  & 

Investment Committee. 

40.  Annually review and reassess the adequacy of this Charter and any bylaw of the Company which relates to the 
Audit Committee, and recommend any proposed changes to the Board for approval. The Chair of the Audit 
Committee  shall  draft  a  proposed  schedule  of  the  Audit  Committee’s  activities  for  the  coming  year  and  the 

times at which such activities shall occur, which shall be submitted to the Audit Committee for its review and 
approval, with such changes as the Audit Committee shall determine to be appropriate.

EXHIBIT B 
Westamerica Bancorporation 
Nominating Committee Charter – Reaffirmed January 27, 2016 

Purpose 
This charter (“Charter”) governs the operations of the Nominating Committee (“Committee”) of the Board of Directors 
(“Board”) of Westamerica Bancorporation (“Company”).  The Committee is responsible for exercising oversight with 

respect  to  the  governance  of  the  Board,  including  reviewing  the  qualifications  of  and  recommending  to  the  Board, 
proposed nominees for election to the Board, reviewing and reporting to the Board on matters of corporate governance 
and leading the Board in their annual evaluation.    

Composition  
The  Committee  shall  be  comprised  of  at  least  three  directors.    All  members  of  the  Committee  shall  meet  the 
independence requirements of and satisfy any other requirements imposed on members of the Committee pursuant to the 
federal securities laws and the rules and regulations of the Securities and Exchange Commission, California state law and 
The Nasdaq Stock Market (“Nasdaq”). 

The other qualifications of individuals to serve on the Committee shall be determined by the Board, and all members 
shall  be  appointed  annually  by  the  Board.   The  Committee  may  form  and  delegate  authority  to  subcommittees  when 
appropriate.  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 filing vacancies.  

Responsibilities 
The Committee shall be responsible for screening and recommending qualified candidates to the Board for membership.  
The  Committee  shall  annually  recommend  a  slate  of  director  nominees  to  be  submitted  for  election  at  each  annual 
meeting  of  shareholders.    The  Committee  will  evaluate  and  consider  all  candidates  submitted  by  shareholders  in 
accordance  with the Company’s bylaws.  The Committee  will consider persons recommended by  shareholders in the 
same  manner  as  Committee-recommended  nominees.      The  Committee  will  carefully  consider  each  existing  Board 
member’s qualifications and contributions to evaluate his or her performance as a director prior to recommending an 

individual for re-nomination each year.  In the case of a vacancy in the office of a director, including a vacancy created 
by an increase in the size of the Board, the Committee shall recommend to the Board an individual to fill such vacancy 
either  through  appointment  by  the  Board  or  through  election  by  shareholders.    If  not  designated  by  the  Board,  the 
Committee may designate a member as its Chairman. 

For the purpose of identifying nominees for the Board, the Committee will rely on personal contacts, the expertise of 
management  and  the  corporate  staff,  and  other  members  of  the  Board  as  deemed  appropriate,  and  may  engage  a 
professional  search  firm  if  the  Committee  deems  it  appropriate  to  do  so.    The  Company  shall  provide  appropriate 
funding, as determined by the Committee, for payment of compensation to any advisors employed by the Committee and 
ordinary administrative expenses that the Committee deems to be necessary or appropriate in carrying out its duties.  The 
Committee or a member or members of the Committee designated by the Committee will interview all candidates. 
The  Committee  shall  be  responsible  for  assessing  the  appropriate  balance of  skills  required  of  Board  members.   The 
Committee may also seek to recommend candidates with specific attributes that may assist the Board to comply with 
industry-specific requirements and other rules and regulations.   

The Committee may recommend to the Board directors believed qualified to serve on each standing committee of the 
Board.   The Board shall approve all appointments to the standing committees of the Board. 

The Committee will perform other functions as may be assigned by the Board or required by federal securities laws, and 
rules and regulations of the SEC, the State of California or Nasdaq.

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;

"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

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.

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

At  December  31,  2015,  the  Company  had  consolidated  assets  of  approximately  $5.2  billion,  deposits  of  approximately  $4.5 
billion  and  shareholders’  equity  of  approximately  $532  million.  The  Company  and  its  subsidiaries  employed  813  full-time 
equivalent staff as of December 31, 2015. 

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. 

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

The FRB generally prohibits a bank holding company from declaring or paying a cash dividend that would impose undue pressure 
on the capital of subsidiary banks or would be funded only through borrowing or other arrangements which might adversely affect
a bank holding company’s financial position. Under the FRB policy, a bank holding company should not continue its existing rate
of cash dividends on its common stock unless its net income is sufficient to fully fund each dividend and its prospective rate of 
earnings retention appears consistent with its capital needs, asset quality and overall financial condition. See the section entitled 
“Restrictions on Dividends and Other Distributions” for additional restrictions on the ability of the Company and the Bank to pay
dividends.

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

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

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

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

Regulation and Supervision of Banks

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

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

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

On July 21, 2010, financial regulatory reform legislation entitled the "Dodd-Frank Wall Street Reform and Consumer Protection 
Act"  (the  "Dodd-Frank  Act")  was  signed  into  law.  The  Dodd-Frank  Act  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.

most bank holding companies. 
Required bank regulatory agencies to seek to make their capital requirements for banks countercyclical so that capital 
requirements increase in times of economic expansion and decrease in times of economic contraction. 
Changed the assessment base for federal deposit insurance from the amount of insured deposits to consolidated assets 
less tangible capital, eliminated the ceiling on the size of the Deposit Insurance Fund ("DIF") and increased the floor of 
the size of the DIF. 
Imposed comprehensive regulation of the over-the-counter derivatives market, which would include certain provisions 
that  would  effectively  prohibit  insured  depository  institutions  from  conducting  certain  derivatives  businesses  in  the 
institution itself. 
Required  large,  publicly  traded  bank  holding  companies  to  create  a  risk  committee  responsible  for  the  oversight  of 
enterprise risk management. 
Implemented  corporate  governance  revisions,  including  with  regard  to  executive  compensation  and  proxy  access  by 
shareholders, that would apply to all public companies, not just financial institutions. 

• Made permanent the $250 thousand limit for federal deposit insurance. 
•

Repealed  the  federal  prohibitions  on  the  payment  of  interest  on  demand  deposits,  thereby  permitting  depository 
institutions to pay interest on business transaction and other accounts. 

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

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 1250% for assets with relatively higher credit  risk, such as 
certain securitizations. A banking organization’s risk-based capital ratios are obtained by dividing its qualifying capital by its total 
risk-adjusted assets and off balance sheet items. 

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

As  of  December  31,  2015,  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 over a transitional period 2015 through 2018.  

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

Prompt Corrective Action and Other Enforcement Mechanisms

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

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

Safety and Soundness Standards

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.

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 
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 

7
- 7 -

 
 
 
 
 
 
 
 
 
companies, both U.S. and non-U.S., that file or are required to file periodic reports under the Securities Exchange Act of 1934
(the “Exchange Act”). 

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

Programs To Mitigate Identity Theft

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

Pending Legislation

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

Competition

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

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

ITEM 1A. RISK FACTORS

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

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

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

Market and Interest Rate Risk

Changes in interest rates could reduce income and cash flow.

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

Changes in capital market conditions could reduce asset valuations.

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

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

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

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

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

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

The Articles of Incorporation of the Company authorize the issuance of 150 million shares of common stock (and two additional 
classes  of  1  million  shares  each,  denominated  “Class  B  Common  Stock”  and  “Preferred  Stock”,  respectively)  of  which

approximately 25.5 million shares of common stock were outstanding at December 31, 2015. Pursuant to its stock option plans, at
December 31, 2015, the Company had outstanding options for 1.5 million shares of common stock, of which 1.1 million were 
currently  exercisable.  As  of  December  31,  2015,  1.5  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,  2015,  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, 2015, real estate served as the principal source of collateral with respect to approximately 53% of 
the Company’s loan portfolio. The Company’s financial condition and operating results will be subject to changes in economic 
conditions in California. The California economy 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 25% 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 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. 

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. 

Following the most recent recession, the FRB has been providing vast amounts of liquidity into the banking system. The FRB has 
been  purchasing  large  quantities  of  U.S.  government  securities,  including  agency-backed  mortgage  securities,  increasing  the 
demand for such securities thereby reducing interest rates. The FRB began reducing these asset purchase activities in the fourth
quarter 2013 and the Federal Open Market Committee increased the target range for the federal funds rate to 1/4 to 1/2 percent on 
December 16, 2015 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 
paragraph. The Company makes certain estimates and judgments in preparing its financial statements. The quality and accuracy 
of those estimates and judgments will have an impact on the Company’s operating results and financial condition. 

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

The Company relies heavily on communications and information systems, including those of third party vendors and other service 
providers,  to  conduct  its  business.  Any  failure,  interruption  or  breach  in  security  of  these  systems  could  result  in  failures  or
disruptions in the Company’s data processing, accounting, customer relationship management and other systems. Communication 
and information systems failures can result from a variety of risks including, but not limited to, events that are wholly or partially 
out  of  the  Company’s  control,  such  as  telecommunication  line  integrity,  weather,  terrorist  acts,  natural  disasters,  accidental 
disasters,  unauthorized  breaches  of  security  systems,  energy  delivery  systems,  cyber  attacks,  and  other  events.  Although  the 

12
- 12 -

 
 
 
 
 
 
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.

As of January 31, 2016, there were approximately 6,100 shareholders of record of the Company’s common stock. 

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

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

(1)

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

(2) 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 48 through 89,
as well as with the other information presented throughout this Report. 

Critical Accounting Policies

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

The  most  significant  accounting  policies  followed  by  the  Company  are  presented  in  Note  1  to  the  consolidated  financial 
statements.  These  policies,  along  with  the  disclosures  presented  in  the  other  financial  statement  notes  and  in  this  discussion,
provide  information  on  how  significant  assets  and  liabilities  are  valued  in  the  financial  statements  and  how  those  values  are 
determined.  Based  on  the  valuation  techniques  used  and  the  sensitivity  of  financial  statement  amounts  to  the  methods, 
assumptions, and estimates underlying those amounts, Management has identified the allowance for 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

In  response  to  the  “great  recession”  of  2008  and  early  2009,  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  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 during the five years ended December 
31,  2015  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 has been 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 loans at December 31, 2015 declined 15.5 percent compared with December 31, 2014 
and net loan losses have also declined from $3.0 million in 2014 to $1.7 million in 2015. The improvement in credit quality has
resulted in Management reducing the provision for loan losses to zero in 2015 from $2.8 million in 2014 and $8.0 million in 2013. 
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 $58.8 million or $2.30 diluted earnings per common share for the year ended December 31, 
2015 compared with net income of $60.6 million or $2.32 diluted earnings per common share for the year ended December 31, 
2014 and net income of $67.2 million or $2.50 diluted earnings per common share for the year ended December 31, 2013.

Comparing 2015 with 2014, net income decreased $1.9 million or 3.1%, primarily due to lower net interest and loan fee income 
(FTE)  and  lower  noninterest  income,  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 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; net loan losses and nonperforming loan volumes have declined relative to earlier periods. Lower
noninterest  income  was  mostly  attributable  to  lower  merchant  processing  service  fees  and  lower  service  charges  on  deposit 
accounts. Noninterest expense decreased primarily due to reduced personnel costs and other operational expenses. 

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 and 
lower  service  charges  on  deposit  accounts.  Noninterest  expense  decreased  mostly  due  to  reduced  OREO  expense  net  of 
disposition gains, lower personnel costs and other operational expenses. 

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  2015 with 2014, net interest and fee income (FTE) decreased $4.4 million or 2.9% primarily due to a lower average 
volume  of  loans  (down  $155  million)  and  lower  yields  on  interest-earning  assets  (FTE)  (down  37  basis  points  “bp”),  partially 
offset by higher average balances of investments (up $436 million) and lower average balances of higher-costing interest-bearing
liabilities. 

Comparing  2014 with 2013, net interest and fee income (FTE) decreased $15.1 million or 9.0% primarily due to a lower average 
volume  of  loans  (down  $182  million)  and  lower  yields  on  interest-earning  assets  (FTE)  (down  41  basis  points  “bp”),  partially 
offset by higher average balances of investments (up $206 million) and lower average balances of higher-costing interest-bearing
liabilities. 

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 3.36% in 2015, 3.70% in 2014 and 4.08% in 2013. During the three years ended December 31, 2015, 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  
assuming 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  prevailing  market  rates;  interest  rates  in  the  two  to  five-year  time  horizon  were  volatile  throughout  2015  providing  some 
opportunity to re-invest cash flows at higher yields.  

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. Federal Home Loan Bank (“FHLB”) advances were 
repaid  in  January  2015.  Average  balances  of  time  deposits  declined  $100  million  in  2015  compared  with  2014.  Lower-cost 
checking and savings deposits accounted for 92.5% of total average deposits in 2015 compared with 89.8% in 2014 and 86.3% in 
2013.

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.

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

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

Provision for Loan Losses

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

The Company provided no provision for loan losses in 2015 compared with $2.8 million in 2014 and $8.0 million in 2013. The 
provision for loan losses is determined based on Management’s evaluation of credit quality for the loan portfolio. The reduction
in the provision for loan losses in 2015 and 2014 reflects the decline in net losses and nonperforming loan volumes during the 
periods relative to earlier periods. 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 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  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 Loan Losses” sections of this report.

In  2015,  noninterest  income  decreased  $3.9  million  or  7.6%  compared  with  2014.  Service  charges  on  deposits  decreased  $2.0 
million compared with 2014 due to declines in fees charged on overdrawn and insufficient funds accounts (down $913 thousand), 
lower fees on analyzed accounts (down $661 thousand) and lower activity on checking accounts (down $325 thousand). Merchant 
processing services declined $880 thousand primarily due to lower transaction volumes. 

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 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 2015, noninterest expense decreased $1.5 million or 1.4% compared with 2014 primarily due to decreases in personnel costs 
and  other  operational  expenses.  Salaries  and  related  benefits  decreased  $2.6  million  primarily  due  to  employee  attrition. 
Amortization  of  identifiable  intangibles  decreased  as  assets  are  amortized  on  a  declining  balance  method.  Courier  expense 
decreased  primarily  due  to  consolidating  service  runs.  OREO  expense  in  2015  included  net  writedowns  while  in  2014  the 
Company  realized  net  gains  on  disposition  of  foreclosed  assets.  Furniture  and  equipment  expense  increased  primarily  due  to 
higher depreciation costs resulting from computer and software upgrades and higher software license fees. 

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. 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. 

Provision for Income Tax

The income tax provision (FTE) was $32.1 million in 2015 compared with $34.2 million in 2014 and $37.0 million in 2013. The 
2015 effective tax rate (FTE) was 35.3% compared with 36.1% in 2014 and 35.5% in 2013. The effective tax rates without FTE 
adjustments were 23.4% for 2015 and 23.2% for 2014 and 22.0% for 2013. The 2015 tax provision included adjustments based on 
filing the 2014 federal and state tax returns and tax benefits from completing audits with the California Franchise Tax Board and 
recognizing  California  enterprise  zone  hiring  credits  for  filed  amended  returns  (2010).  The  2014  tax  provision  reflected  an 
adjustment  based  on  filing  2013  federal  tax  return  and  tax  benefits  from  completing  audits  with  the  California  Franchise  Tax 
Board.  

Effective January 1, 2014, the new legislation signed by California’s Governor Jerry Brown 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, agency and non-agency mortgage backed securities, state and political subdivisions, corporations, and asset-backed and
other securities. Investment securities are held in safekeeping by an independent custodian. 

Management has increased the investment portfolio in response to deposit growth and loan volume declines. The carrying value 
of the Company’s investment securities portfolio was $2.9 billion as of December 31, 2015, an increase of $247 million compared
to December 31, 2014.

Management  continually  evaluates  the  Company’s  investment  securities  portfolio  in  response  to  established  asset/liability 
management objectives, changing market conditions that could affect profitability, liquidity, and the level of interest rate risk to 
which the Company is exposed.  These evaluations may cause Management to change the level of funds the Company deploys 
into investment securities, 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’s  positioning  of  the  balance  sheet  for  rising  interest  rates  has  resulted  in  the  purchase  of  floating  rate  corporate
bonds, federal agency bonds, mortgage-backed securities, and short-term state and municipal bonds. As of December 31, 2015, 
substantially  all  of  the  Company’s  investment  securities  continue  to  be  investment  grade  rated  by  one  or  more  major  rating 
agencies.  In  addition  to  monitoring  credit  rating  agency  evaluations,  Management  performs  its  own  evaluations  regarding  the 
credit worthiness of the issuer or the securitized assets underlying asset-backed securities. 

The  Company’s  procedures  for  evaluating  investments  in  securities  are  in  accordance  with  guidance  issued  by  the  Board  of 
Governors of the Federal Reserve System, “Investing in Securities without Reliance on Nationally Recognized Statistical Rating 
Agencies” (SR 12-15) and other regulatory guidance. 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. 

The following table shows the fair value carrying amount of the Company’s investment securities available for sale as of the dates

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

Loan Portfolio 

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

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

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

The  Company  issues  formal  commitments  on  lines  of  credit  to  well-established  and  financially  responsible  commercial 
enterprises. Such commitments can be either secured or unsecured and are typically in the form of revolving lines of credit for
seasonal working capital needs. Occasionally, such commitments are in the form of letters of credit to facilitate the customers’
particular business transactions. Commitment fees are generally charged for commitments and letters of credit. Commitments on 
lines of credit and letters of credit typically mature within one year. For further information, see the accompanying notes to the 
consolidated financial statements. 

Loan Portfolio Credit Risk 

The  Company  extends  loans  to  commercial  and  consumer  customers  which  expose  the  Company  to  the  risk  borrowers  will 
default,  causing  loan  losses.  The  Company’s  lending  activities  are  exposed  to  various  qualitative  risks.  All  loan  segments  are 
exposed to risks inherent in the economy and market conditions. Significant risk characteristics related to the commercial loan
segment  include  the  borrowers’  business  performance  and  financial  condition,  and  the  value  of  collateral  for  secured  loans.

Significant risk characteristics related to the commercial real estate segment include the borrowers’ business performance and the 
value of properties collateralizing the loans. Significant risk  characteristics related to the construction loan segment include the 
borrowers’  performance  in  successfully  developing  the  real  estate  into  the  intended  purpose  and  the  value  of  the  property 
collateralizing  the  loans.  Significant  risk  characteristics  related  to  the  residential  real  estate  segment  include  the  borrowers’ 
financial  wherewithal  to  service  the  mortgages  and  the  value  of  the  property  collateralizing  the  loans.  Significant  risk 
characteristics related to the consumer loan segment include the financial condition of the borrowers and the value of collateral 
securing the loans. 

The preparation of the financial statements requires Management to estimate the amount of losses inherent in the loan portfolio
and establish an allowance for credit losses. The allowance for credit losses is established by assessing a provision for loan losses 
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.

At December 31, 2015, two loans secured by commercial real estate totaling $10,990 thousand were on nonaccrual status. The 
remaining sixteen nonaccrual loans held at December 31, 2015 had an average carrying value of $251 thousand and the largest 
carrying value was $1,323 thousand. 

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

Allowance for Credit Losses

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

The  following  table  summarizes  the  allowance  for  credit  losses,  chargeoffs  and  recoveries  of  the  Company  for  the  periods 
indicated:

The  Company's  allowance  for  loan  losses  is  maintained  at  a  level  considered  appropriate  to  provide  for  losses  that  can  be 
estimated based upon specific and general conditions. These include conditions unique to individual borrowers, as well as overall
loan loss experience, the amount of past due, nonperforming and classified loans, 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 loan 
loss experience of loan portfolio segments to determine standard loss rates for each segment. The loss rate for each loan portfolio 
segment reflects both the historical loss experience during a look-back period and 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  loan  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  loan  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 loan 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 loan default discounts ascribed to each segment. Management establishes allocations of the allowance for loan 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, 2015 are economic and business conditions $1.0 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 $1.2 million, adequacy of lending Management and staff $1.3 million, 
concentrations of credit $2.5 million, and other factors.  

The following table presents the allocation of the allowance for loan losses as of December 31 for the years indicated:

The  Company  allocated  more  allowance  for  loan  losses  to  the  commercial  loan  category  at  December  31,  2015,  due  to  more 
reserve being allocated to individually evaluated loans. At December r31, 2015, the decline in the unallocated was generally due
to the overall improved credit quality metrics. 

Management considers the $29.8 million allowance for loan losses to be adequate as a reserve against loan losses inherent in the
loan portfolio as of December 31, 2015. 

See Note 3 to the consolidated financial statements for additional information related to the loan portfolio, loan portfolio credit
risk, and allowance for loan 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  (“FOMC”)  increased  the  target  range  for  the  federal  funds  rate  to  1/4  to  1/2  percent  on 
December 16, 2015. Interest rates on United States Treasury obligations declined from January 1, 2016 through January 27, 2016.
The  FOMC’s  January  27,  2016  press  release  stated  “Information  received  since  the  Federal  Open  Market  Committee  met  in 
December suggests that labor market conditions improved further even as economic growth slowed late last year…Market-based 
measures  of  inflation  compensation  declined  further;  survey-based  measures  of  longer-term  inflation  expectations  are  little 
changed, on balance, in recent months…The Committee is closely monitoring global economic and financial developments and is 
assessing their implications for the labor market and inflation, and for the balance of risks to the outlook…Given the economic
outlook,  the  Committee  decided  to  maintain  the  target  range  for  the  federal  funds  rate  at  1/4  to  1/2  percent.  The  stance  of 
monetary policy remains accommodative, thereby supporting further improvement in labor market conditions and a return to 2 
percent  inflation.  In  determining  the  timing  and  size  of  future  adjustments  to  the  target  range  for  the  federal  funds  rate,  the
Committee  will  assess  realized  and  expected  economic  conditions  relative  to  its  objectives  of  maximum  employment  and  2 
percent  inflation.”    In  this  context,  Management  expects  a  high  level  of  uncertainty  in  regard  to  interest  rate  levels  in  the 
immediate  term,  and  Management’s  most  likely  earnings  forecast  for  the  twelve  months  ending  December  31,  2016  assumes 
market interest rates will either remain at relatively low levels or short-term rates will rise gradually.

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, 2015, 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  or  gradually  increasing 
interest rates in the near-term and intermediate term. 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 chargeoffs and the provision for loan losses. The financial 
condition  and  liquidity  of  debtors  issuing  bonds  and  debtors  whose  mortgages  or  other  obligations  are  securitized  can  directly 
impact  the  credit  quality  of  the  Company’s  investment  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
2015 and 2014. The stability of the Company’s funding from customer deposits is in part reliant on the confidence clients have in 
the Company. The Company places a very high priority in maintaining this confidence through conservative credit and capital 
management practices and by maintaining an appropriate level of liquidity reserves. 

Liquidity is further provided by assets such as balances held at the Federal Reserve Bank, investment securities, and amortizing
loans. The Company's investment securities portfolio provides a substantial secondary liquidity reserve. The Company held $2.9 
billion  in  total  investment  securities  at  December  31,  2015.  Under  certain  deposit,  borrowing  and  other  arrangements,  the

Company must hold and pledge investment securities as collateral. At December 31, 2015, such collateral requirements totaled 
approximately $739 million. 

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

Management  will  monitor  the  Company’s  cash  levels  throughout  2016.  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  volatility  in  economic 
conditions,  competition  and  political  uncertainty,  loan  demand  and  levels  of  customer  deposits  are  not  certain.  Shareholder 
dividends  are expected  to  continue  subject to  the  Board's discretion  and continuing  evaluation  of  capital  levels,  earnings,  asset 
quality and other factors. 

Westamerica Bancorporation ("Parent Company") is a separate entity apart from Westamerica Bank (“Bank”) and must provide 
for  its  own  liquidity.  In  addition  to  its  operating  expenses,  the  Parent  Company  is  responsible  for  the  payment  of  dividends 
declared  for  its  shareholders,  and  interest  and  principal  on  any  outstanding  debt.  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 2015 and 2014 to pay shareholder dividends of $39 million and $40 million, respectively, and retire 
common stock in the amount of $15 million and $53 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.

the  consolidated  financial  statements.  The  purchase  obligation  consists  of  the  Company’s  minimum  liabilities  under  contracts 
with third-party automation services providers.

Capital Resources

The Company has historically generated high levels of earnings, which provides a means of accumulating capital. The Company's 
net income as a percentage of average shareholders' equity (“return on equity” or “ROE”) has been 11.3% in 2015, 11.6% in 2014 
and 12.5% in 2013. The Company also raises capital as employees exercise stock options. Capital raised through the exercise of 
stock options was $5 million in 2015 compared with $12 million in 2014 and $21 million in 2013. 

The Company paid common dividends totaling $39 million in 2015, $40 million in 2014 and $40 million in 2013, which represent 
dividends  per  common  share  of  $1.53,  $1.52  and  $1.49,  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 344 thousand shares valued at $15 million in 2015, 1.0 million shares valued at $53 million in 2014 and 1.2 million shares
valued at $57 million in 2013. 

The Company's primary capital resource is shareholders' equity, which was $532 million at December 31, 2015 compared with 
$527 million at December 31, 2014. The Company's ratio of equity to total assets was 10.30% at December 31, 2015 and 10.46% 
at December 31, 2014. 

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

Capital to Risk-Adjusted Assets 

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

•
•
•
•
•

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

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

Banking organizations that are not subject to the “advanced approaches rule” began complying with the final rule on January 1, 
2015; on such date, the Company and the Bank became subject to the revised definitions of regulatory capital, the new minimum 
regulatory  capital  ratios,  and  various  regulatory  capital  adjustments  and  deductions  according  to  transition  provisions  and 
timelines. All banking organizations began calculating standardized total risk-weighted assets on January 1, 2015. The transition 
period for the capital conservation buffer for all banking organizations 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 did not supersede provisions of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) requiring 
federal banking agencies to take prompt corrective action (PCA) to resolve problems of insured depository institutions. The final
rule  revised  the  PCA  thresholds  to  incorporate  the  higher  minimum  levels  of  capital,  including  the  newly  proposed  “common 
equity tier 1” ratio.

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.

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

The  Company’s  strategy  includes  building  the  value  of  its  deposit  base  by  building  balances  of  lower-costing  deposits  and 
avoiding reliance on higher-costing time deposits. From 2013 to 2015 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 93% of average balances of total deposits in 2015 compared with 90% in 2014 and 86% in 2013. 

Total time deposits were $287 million and $385 million at December 31, 2015 and 2014, respectively.  The following table sets 
forth, by time remaining to maturity, the Company’s total domestic time deposits. The Company has no foreign time deposits.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

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

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Management of Westamerica Bancorporation and subsidiaries (the “Company”) is responsible for establishing and maintaining 
adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over 
financial reporting as of December 31, 2015. 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,  2015  based  upon  criteria  in  Internal  Control  —  Integrated  Framework  (2013)  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, Management determined that the 
Company’s  internal  control  over  financial  reporting  was  effective  as  of  December  31,  2015  based  on  the  criteria  in  Internal 
Control - Integrated Framework (2013) issued by COSO. 

The Company’s independent registered public accounting firm has issued an attestation report on Management’s assessment of 
the Company’s internal control over financial reporting. Their opinion and attestation on internal control over financial reporting 
appear on page 90.

WESTAMERICA BANCORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Business and Accounting Policies

Westamerica Bancorporation, a registered bank holding company (the “Company”), provides a full range of banking services to 
corporate  and  individual  customers  in  Northern  and  Central  California  through  its  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  2016  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. Cash 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,  agency  and  non-agency  mortgage-backed  securities,  asset-backed  securities  and  equity  securities. 
Securities transactions are recorded on a trade date basis. The Company classifies its debt and marketable equity securities in one 
of  three  categories:  trading,  available  for  sale  or  held  to  maturity.  Trading  securities  are  bought  and  held  principally  for  the
purpose of selling them in the near term. Trading securities are recorded at fair value with unrealized gains and losses included in 
earnings. Held to maturity securities are those debt securities which the Company has the ability and intent to hold until maturity. 
Held to maturity securities are recorded at cost, adjusted for the amortization of premiums or accretion of discounts. Securities not 
included in trading or held to maturity are classified as available for sale. Available for sale securities are recorded at fair value. 
Unrealized  gains  and  losses,  net  of  the  related  tax  effect,  on  available  for  sale  securities  are  included  in  other  comprehensive
income. 

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

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

security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration 
in  the  financial  condition  of  the  issuer,  and  the  Company  does  not  intend  to  sell  or  be  required  to  sell  the  securities  before 
recovery of its amortized cost. An unrealized loss in the value of an equity security is generally considered temporary when the
fair value of the security declined primarily due to current market conditions and not deterioration in the financial condition of the 
issuer, the Company expects the fair value of the security to recover in the near term and the Company does not intend to sell or
be  required  to  sell  the  securities  before  recovery  of  its  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 
recognized in interest income. Other fees, including those collected upon principal prepayments, are included in interest income

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

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

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

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

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

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

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

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

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

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

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

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

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 
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.

Measurement  of  Financial  Assets  and  Financial  Liabilities,  was  issued  January  2016.    The  ASU  addresses  certain  aspects  of 
recognition,  measurement,  presentation,  and  disclosure  of  financial  instruments.    Most  notably,  the  ASU  changes  the  income 
statement impact of equity investments held by the Company and the requirement for the Company to use the exit price notion 
when measuring the fair value of financial instruments for disclosure purposes. 

The Company will be required to adopt the ASU provisions on January 1, 2018.  Management is evaluating the impact that the 
ASU will have on the Company’s financial statements.

Expected maturities of mortgage-related securities can differ from contractual maturities because borrowers have the right to call
or prepay obligations with or without call or prepayment penalties. In addition, such factors as prepayments and interest rates may 
affect the yield on the carrying value of mortgage-related securities. At December 31, 2015 and December 31, 2014, 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-backed and asset-
backed  securities,  delinquency  and  loss  information  with  respect  to  the  underlying  collateral,  changes  in  the  levels  of

subordination  for  the  Company’s  particular  position  within  the  repayment  structure  and  remaining  credit  enhancement  as 
compared to expected credit losses of the security. Substantially all of these securities continue to be investment grade rated by a 
major  rating  agency.  In  addition  to  monitoring  credit  rating  agency  evaluations,  Management  performs  its  own  evaluations 
regarding the credit worthiness of the issuer or the securitized assets underlying asset backed securities. 

The Company does not intend to sell any investments and has concluded that it is more likely than not that it will not be required 
to sell the investments prior to recovery of the amortized cost basis. Therefore, the Company does not consider these investments 
to be other-than-temporarily impaired as of December 31, 2015. 

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

As  of  December  31,  2015,  $738,865  thousand  of  investment  securities  were  pledged  to  secure  public  deposits  and  short-term 
borrowed funds. As of December 31, 2014, $757,623 thousand of investment securities were pledged to secure public deposits, 
short-term borrowed funds and FHLB advances.

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.

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, 2015. The intrinsic 
value is calculated as the difference between the market value as of December 31, 2015 and the exercise price of the shares. The
market value as of December 31, 2015 was $46.75 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, 2015,  2014  and 2013,  the  Company  granted 343  thousand, 294  thousand  and 322  thousand  stock 
options, respectively. The following weighted average assumptions were used in the option pricing to value stock options granted
in the periods indicated:

December 31, 2015, no shares of Class B Common Stock or Preferred Stock were outstanding. 

Note 9: Risk-Based Capital 

The  Company  and  the  Bank  were  well  capitalized  under  the  regulatory  framework  effective  January  1,  2015.  To  be  well 
capitalized, the institution must maintain a total risk-based capital ratio as set forth in the following table and not be subject to a 
capital directive order. As of December 31, 2015, the Company and the Bank met all capital adequacy requirements to which they 
are subject. 

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

•
•
•
•
•

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

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

Banking organizations that are not subject to the “advanced approaches rule” began complying with the final rule on January 1, 
2015; on such date, the Company and the Bank became subject to the revised definitions of regulatory capital, the new minimum 
regulatory  capital  ratios,  and  various  regulatory  capital  adjustments  and  deductions  according  to  transition  provisions  and 
timelines. All banking organizations began calculating standardized total risk-weighted assets on January 1, 2015. The transition 
period for the capital conservation buffer for all banking organizations 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 did not supersede provisions of the Federal Deposit Insurance Corporation Improvement Act (FDICIA) requiring 
federal banking agencies to take prompt corrective action (PCA) to resolve problems of insured depository institutions. The final
rule  revised  the  PCA  thresholds  to  incorporate  the  higher  minimum  levels  of  capital,  including  the  newly  proposed  “common 
equity tier 1” ratio. 

The capital ratios for the Company and the Bank under the new capital framework are presented in the table below.

Note 10: Income Taxes

Deferred  tax  assets  and  liabilities  are  recognized  for  future  tax  consequences  attributable  to  differences  between  the  amounts 
reported in the financial statements of existing assets and liabilities and their respective tax basis and operating loss and tax credit 
carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the 
years in which those temporary differences are expected to be recovered or settled. Amounts for the current year are based upon
estimates and assumptions as of the date of these financial statements and could vary significantly from amounts shown on the tax
returns as filed. 

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

Deferred tax asset

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

Based on Management’s judgment, a valuation allowance is not needed to reduce the gross deferred tax asset because it is more 
likely than not that the gross deferred tax asset will be realized through recoverable taxes or future taxable income. Net deferred 
tax assets are included with other assets in the Consolidated Balance Sheets.

The Company does not anticipate any significant increase or decrease in unrecognized tax benefits during 2016. Unrecognized tax
benefits at December 31, 2015 and 2014 include accrued interest and penalties of $88 thousand and $93 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, 2015, 2014, 2013 and 2012 remain subject to examination by the Internal Revenue Service. The tax years ended December 
31, 2015, 2014, 2013, 2012 and 2011 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  and  equity  securities,  which  are  traded  by  dealers  or  brokers  in  active 
markets.  Valuations  are  obtained  from  readily  available  pricing  sources  for  market  transactions  involving  identical  assets  or 
liabilities. 

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

The Company regularly reviews the valuation techniques and assumptions used by its vendors and determines which valuation 
techniques  are  utilized  based  on  observable  market  inputs  for  the  type  of  securities  being  measured.  The  Company  uses  the 
information to determine the placement in the fair value hierarchy as level 1, 2 or 3. When the Company changes its valuation 
assumptions for measuring financial assets and financial liabilities at fair value, either due to changes in current market conditions 
or other factors, or reevaluates the valuation techniques and assumptions used by its vendors, it may need to transfer those assets
or liabilities to another level in the hierarchy based on the new information. The Company recognizes these transfers at the end of 
the  reporting  period  that  the  transfers  occur.  During  the  quarter  ended  June  30,  2015,  the  Company  reevaluated  the  valuation 
techniques  and  assumptions  used  by  its  vendors  in  valuing  the  Company’s  available  for  sale  securities,  and  based  on  the 
evaluation, transferred $437,715 thousand out of level 1 and transferred $437,715 thousand into level 2. There were no transfers
into level 1 or into or out of level 3. Subsequent to June 30, 2015 and through the year ended December 31, 2015, and the year 
ended December 31, 2014, there were no transfers into 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,  2015  and  December  31,  2014,  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 3 – Valuation is based upon independent market prices, estimated liquidation values of loan collateral or appraised value of 
the collateral as determined by third-party independent appraisers, less 10% for selling costs, generally. Level 3 includes other 
real estate owned that has been measured at fair value upon transfer to foreclosed assets and impaired loans collateralized by real
property and other business asset collateral where a specific reserve has been established or a chargeoff has been recorded. Losses 
on  other  real  estate  owned  represent  losses  recognized  in  earnings  during  the  period  subsequent  to  its  initial  classification  as
foreclosed assets. The unobservable inputs and qualitative information about the unobservable inputs are not presented due to the

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  chargeoff  has  been  recorded. 
Losses on other real estate owned represent losses recognized in earnings during the period subsequent to its initial classification 
as foreclosed assets. 

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 chargeoff 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 
$29,771 thousand at December 31, 2015 and $31,485 thousand at December 31, 2014 and the purchased loan discount associated 
with purchased covered and purchased non-covered loans of $152 thousand and $6,432 thousand, respectively at December 31, 
2015  and  of  $468  thousand  and  $9,372  thousand,  respectively  at  December  31,  2014  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. 

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. 

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 64 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, 2015 are as follows:

The  total  minimum  lease  payments  have  not  been  reduced  by  minimum  sublease  rentals  of  $2,076  thousand  due  in  the  future 
under  noncancelable  subleases.  Total  rentals  for  premises  were $8,359  thousand  in 2015,  $8,798  thousand  in  2014  and $8,953 
thousand in 2013. Total sublease rentals were $1,721 thousand in 2015, $1,833 thousand in 2014 and $1,852 thousand in 2013. 
Total  rentals  for  premises,  net  of  sublease  income,  included  in  noninterest  expense  were  $6,638  thousand  in  2015,  $6,965 
thousand in 2014 and $7,101 thousand in 2013.  

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  $299,884  thousand  and  $312,694  thousand  at  December  31,  2015  and  December  31,  2014,  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 $26,149 thousand and $29,002 thousand at December 31, 2015 and December 31, 2014, respectively. The Company also 
had commitments for commercial and similar letters of credit of $40 thousand at December 31, 2015 and December 31, 2014. At 
December  31,  2015  and  December  31,  2014,  the  Company  had  a  reserve  for  unfunded  commitments  of  $2,593  thousand  and 
$2,693 thousand, respectively, included in other liabilities.

Due to the nature of its business, the Company is subject to various threatened or filed legal cases. Based on the advice of legal 
counsel,  the  Company  does  not  expect  such  cases  will  have  a  material,  adverse  effect  on  its  financial  position  or  results  of 
operations. Legal liabilities are accrued when obligations become probable and the amount 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 $734 thousand in 2015, $1,002 thousand in 2014 and $1,200 thousand in 
2013. 

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  $1,147  thousand  in  2015,  $1,159  thousand  in  2014  and  $1,214 
thousand in 2013. 

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:

The  above  discount  rate  is  based  on  the  Corporate  Aa  25-year  rate,  the  term  of  which  approximates  the  term  of  the  benefit 
obligations.  The  Company  reserves  the  right  to  terminate  or  alter  post-employment  health  benefits.  Post-retirement  medical 
benefits  are  currently  fixed  amounts  without  provision  for  future  increases;  as  a  result,  the  assumed  annual  average  rate  of 
inflation used to measure the expected cost of benefits covered by this program is zero percent for 2016 and beyond. 

Assumed benefit inflation rates are not applicable for this program.

Note 15: Related Party Transactions 

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

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 2015. 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 $254,600 thousand in 2015 and $400,039 thousand in 2014, 
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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors 
Westamerica Bancorporation 
San Rafael, California 

We have audited the accompanying consolidated balance sheet of Westamerica Bancorporation (the “Company”) as of December 
31, 2015, and the related consolidated statements of income, comprehensive income, changes in shareholders' equity, and cash 
flows for the year then ended. We also have audited the Company's internal control over financial reporting as of December 31, 
2015, based on criteria established in the 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). The Company's management is responsible for these consolidated financial 
statements,  for  maintaining  effective  internal  control  over  financial  reporting,  and  for  its  assessment  of  the  effectiveness  of
internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial 
Reporting. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company's 
internal control over financial reporting 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 audits to obtain reasonable assurance about whether the financial statements 
are  free of  material  misstatement  and whether  effective  internal  control  over financial  reporting was  maintained  in  all  material
respects.  Our  audit  of  the  financial  statements  included  examining,  on  a  test  basis,  evidence  supporting  the  amounts  and 
disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management,
and  evaluating  the  overall  financial  statement  presentation.  Our  audit  of  internal  control  over  financial  reporting  included 
obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  and
testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the  assessed  risk.  Our  audits  also 
included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a
reasonable basis for our opinions. 

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 consolidated financial statements referred to above present fairly, in all material respects, the financial position 
of  the  Company  as  of  December  31,  2015,  and  the  results  of  its  operations  and  its  cash  flows  for  the  year  then  ended  in 
conformity  with  accounting  principles  generally  accepted  in  the  United  States  of  America.  Also  in  our  opinion,  the  Company 
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria
established in the 2013 Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission.

equity,  and  cash  flows  for  each  of  the  years  in  the  two-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 Westamerica Bancorporation and subsidiaries as of December 31, 2014, and the results of their operations and their cash flows
for  each  of  the  years  in  the  two-year  period  ended December 31,  2014,  in  conformity  with  U.S. generally  accepted  accounting 
principles.

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

As  previously  reported  in  the  Company’s  current  report  on  Form  8-K  filed  March  3,  2015,  the  Company  engaged  a  new 
independent  accounting  firm  for  the  fiscal  year  ending  December  31,  2015.  There  have  been  no  disagreements  between  the 
Company and the previous independent accounting firm or current independent accounting firm. 

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, 2015. 

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,  2015  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 page 47 and 90, respectively.
