PROXY STATEMENT

March 12, 2012
___________

GENERAL

The Westamerica Board of Directors is soliciting proxies to be used at the 2012 Annual Meeting of Shareholders
of Westamerica Bancorporation, which will be held at 11:00 a.m. Pacific Time, Thursday, April 26, 2012, or at
any adjournment or postponement of the Annual Meeting. Proxies are solicited to give all Shareholders of Record
(“Record 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 on at the Annual Meeting.

Voting Information

Proxy Statement Availability: This year Westamerica has elected to take advantage of the Securities and
Exchange Commission’s (the “SEC”) rule that allows us to furnish proxy materials to you online. We believe
electronic delivery will expedite shareholders’ receipt of materials, while lowering costs and reducing the
environmental impact of our annual meeting by reducing printing and mailing of full sets of materials. On 
March 12, 2012, we mailed to our shareholders a Notice (the “Notice of Internet Availability of Proxy Materials”
or “Notice”) containing instructions on how to access our proxy statement and annual report online. If you
received a Notice by mail, you will not receive a printed copy of the materials, unless you specifically request one.
The Notice contains instructions on how to receive a paper copy of the materials.

Who Can Vote. You are entitled to vote if you were a “Record Holder” of Westamerica common stock as 
of the close of business on February 27, 2012. Your shares can be voted at the Meeting only if you are present 
or represented by a valid proxy. If your shares of common stock are held by a bank, broker or other nominee in
“street name,” you are a “beneficial owner” and will receive voting instructions from the bank, broker or other
nominee (including instructions, if any, on how to vote). You must follow these instructions in order to have
your shares voted. 

Voting in Person at the Meeting. To be able to vote in person at the Annual Meeting, Record Holders must
provide photo identification, while beneficial owners must obtain and bring to the Annual Meeting a legal
proxy from the institution that holds your shares, indicating that you were the beneficial owner of the shares on
February 27, 2012, the Record Date for voting. 

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 approval of the 2012 Amended and Restated Stock Option Plan of 1995, and
FOR ratifying the selection of independent auditors. The Proxies will also have discretionary authority to vote in
accordance with their judgment on any other matter that may properly come before the Meeting that we did not
have notice of by January 27, 2012.

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 Meeting. A quorum is calculated based on the number of shares
represented by shareholders attending in person or by proxy. On February 27, 2012, 28,093,899 shares of
Westamerica common stock were outstanding. We also count broker non-votes, which we describe below, 
as shares present or represented at the Meeting for the purpose of determining whether a quorum exists.

Required Votes for Proposal 1 – 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 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 or against the
election of that nominee. 

Required Votes for Proposal 2 – Approve a Non-Binding Advisory Vote on the Compensation of Our
Named Executive Officers. The executive compensation of the named executive officers will be approved if the
number of shares voted in favor of the proposal is equal to at least a majority of the shares represented and voting at
the Meeting, in person or by proxy, and also a majority of the required quorum. Because your vote is advisory, it will
not be binding on the Board or the Corporation. However, the Board will review the voting results and take them
into consideration when making future decisions regarding executive compensation. Abstentions and broker non-
votes will have the same effect as an against vote if votes in favor are less than a majority of the required quorum. 

Required Votes for Proposal 3 – Approve the 2012 Amended and Restated Stock Option Plan of 1995.  

If a quorum exists, Proposal 3 must receive the affirmative vote of a majority of the shares present in person or
represented by proxy at the Annual Meeting and entitled to vote on this proposal. Therefore, abstentions will have
the same effect as voting against the proposal. Broker non-votes will not be counted as eligible to vote on the
proposal and, therefore, will have no effect on the outcome of the voting so long as the quorum was voted on this
proposal to be approved. If you hold your shares in street name and do not provide voting instructions to your
broker, your shares will not be voted on this proposal since your broker does not have discretionary authority to
vote (a “broker non-vote”). Properly completed ballots submitted prior to the Annual Meeting will be voted in the
way you direct. If you do not specify instructions, the shares represented by those properly completed proxies will
be voted to approve the 2012 Amended and Restated Stock Option Plan of 1995.

Required Votes for Proposal 4 – Ratify Selection of Independent Auditor. The selection of the independent
auditor will be ratified if the number of shares voted in favor of the proposal is equal to at least a majority of the shares
represented at the Meeting, in person or by proxy, provided such votes in favor also constitute a majority of the required
quorum. Abstentions are deemed “present” for the purpose of obtaining a quorum, but for purposes of determining
the outcome of the proposal, abstentions will not be treated as affirmative votes. In other words, abstentions will have
the same effect as an against vote if votes in favor are less than a majority of the required quorum.

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

Broker Non-Votes. Broker non-votes will be included as “present” for the purpose of determining the presence of
a quorum. A broker non-vote occurs under the stock exchange rules when a broker is not permitted to vote on a
matter without instructions from the beneficial owner of the shares and no instruction is given on a timely basis.
Brokers may vote at their discretion on routine matters, such as ratification of selection of independent auditors,
but not on non-routine matters, including election of Directors, compensation of named executive officers, and
approval of the 2012 Amended and Restated Stock Option Plan of 1995. Your vote is IMPORTANT; therefore,
please mark your ballot to ensure that your votes for all proposals are counted.

How You Can Vote. Record Holders may vote by proxy or in person at the Meeting. To vote by proxy, you may
select one of the following options:

Vote by Telephone. You can vote your shares by telephone by calling the toll-free telephone number shown on
your Proxy Card and following the recorded instructions. Telephone voting is available 24 hours a day, seven days
a week. Voice prompts allow you to vote your shares and confirm that your instructions have been properly
recorded. Our telephone voting procedures are designed to authenticate the shareholder by using individual
control numbers, which you will find on your Proxy Card. If you vote by telephone, you should NOT return your
Proxy Card or vote by internet.

Vote by Internet. You can choose to vote on the internet. The website for internet voting is shown on your
Notice of Internet Availability of Proxy Materials or your Proxy Card. Internet voting is available 24 hours a day,
seven days a week. You will be given the opportunity to confirm that your instructions have been properly
recorded. Our internet voting procedures are designed to authenticate the shareholder by using individual control
numbers, which you will find on your Proxy Card. If you vote on the internet, you should NOT return your
Proxy Card or vote by telephone.

If you vote by telephone or internet, your vote must be received by 1:00 a.m. Central Time, on April 26,
2012 to ensure that your vote is counted. For Westamerica Bancorporation Tax Deferred Savings/Retirement
Plan (ESOP) participants, your vote must be received by 12:01 a.m. Central Time, on April 24, 2012.

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

Vote by Mail. If you choose to vote by mail, simply mark your Proxy Card, date and sign it, and return it in the
postage-paid envelope provided. Beneficial owners must follow voting instructions received from your bank,
broker or other nominee in order to have your shares voted. 

Revocation of Proxy. Record Holders who vote by proxy, whether by telephone, internet or mail, may revoke
that proxy at any time before it is voted at the Meeting. You may do this by: (a) signing another Proxy Card with a
later date and delivering it to us prior to the Meeting or sending a notice of revocation to the Corporate Secretary
of Westamerica at 1108 Fifth Avenue, San Rafael, CA 94901; (b) voting at a later time by telephone or on the
internet prior to 1:00 a.m. Central Time, on April 26, 2012 (prior to 12:01 a.m. Central Time, on April 24, 2012
for ESOP participants); or (c) attending the Meeting in person and casting a ballot. If you hold shares in street
name, you may change your vote by submitting new voting instructions to your broker or other nominee.

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

Section 16(a) Beneficial Ownership Reporting Compliance

initial reports of ownership and reports of changes in ownership of common stock and other equity securities of
the Corporation, and to send a copy to the Corporation.

To the Corporation’s knowledge and based solely on a review of the copies of reports furnished to the

THE BOARD OF DIRECTORS RECOMMENDS ELECTION OF ALL NOMINEES.

Director Independence and Leadership Structure

Board of Directors and Committees

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

Our Board believes that the most effective leadership structure for the Corporation at this time is to combine

the responsibilities of the Chairman and CEO, a structure that has been successful since 1989. The combined
positions avoid a duplication of efforts, enable decisive leadership, ensure a clear accountability for the
performance of the Corporation, a more rapid implementation of decisions, and a consistent vision. Given the size
of our employee base and our level of assets relative to larger, more complex banking structures, our Corporation is
particularly well suited to combine the Chairman and CEO functions. Furthermore, our management team has
an average tenure of 24 years and does not require the substantial oversight needed by a less experienced team,
which has allowed our Chairman and CEO to lead the Corporation through eleven acquisitions since 1992. 

To ensure strong Board oversight eight of our nine Directors are, as noted above, independent as defined by

NASDAQ. Only non-management directors sit on Board committees, with the exception of the Executive
Committee, and every non-management director sits on one or more of these Committees. All non-management
directors meet at least four times a year outside the presence of the Chairman and CEO and although a lead
director has not been appointed, pertinent information from these meetings is regularly communicated to the
Chairman and CEO. The Board completes an annual board evaluation that is discussed by the Nominating
Committee and presented to the full Board.

The Board of the Corporation also serves as the Board of Directors of Westamerica Bank, and as such is well

informed of Bank operations through regular reports and discussions on the operations of the Bank. The
Directors’ longevity with the Corporation has exposed them to a wide range of business cycles which plays a
critical role in maintaining the profitability of the Corporation through the current economic environment.

Role of the Board of Directors in Risk Oversight

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

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

ongoing evaluations of loan portfolios and risk-rating of individual loans using guidelines established by bank
regulatory authorities.

Meetings

The Corporation expects all Board Members to attend all meetings, including the Annual Meeting of
Shareholders, except for reasons of health or special circumstances. Last year all nine Directors attended the
Annual Meeting. The Board held a total of 10 meetings during 2011. Every Director attended at least 75% 
of the aggregate of: (i) the Board Meetings held during that period in which they served; and (ii) the total number
of meetings of any Committee of the Board on which the Director served.

Number of Meetings

Executive Committee:

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

Audit Committee:

The Board of Directors has determined that all members are independent, as that term is defined by
applicable rules of NASDAQ for Audit Committee purposes. The Board has also designated Mr. Nelson as the
“Audit Committee financial expert” as defined by the rules of the SEC and has determined that he is
“financially sophisticated” under NASDAQ rules. In concluding that Mr. Nelson is the Audit Committee
financial expert, the Board determined that he has:
    (cid:129) an understanding of generally accepted accounting principles and financial statements; 
    (cid:129) the ability to assess the general application of such principles in connection with the accounting for 
     estimates, accruals and reserves; 
    (cid:129) experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and 
     level of complexity of accounting issues that are generally comparable to the breadth and complexity of 
     issues that can reasonably be expected to be raised by the Corporation’s financial statements, or experience 
     actively supervising one or more persons engaged in such activities;
    (cid:129) an understanding of internal control over financial reporting; and 
    (cid:129) an understanding of Audit Committee functions.

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

Functions:  The Audit Committee provides independent, objective oversight of the integrity of the
Corporation’s financial statements, the Corporation’s compliance with legal and regulatory requirements, the
independence and performance of the Corporation’s independent auditor as it performs audit, review or attest
services, and the Corporation’s internal audit and control function. It selects and retains the independent
auditors, reviews the plan and the results of the auditing engagement. It acts pursuant to a written charter that
was last amended by the Board in January 2011 and was attached as an exhibit to the Proxy Statement for the
2011 Annual Meeting of Shareholders. The Audit Committee Report that follows below more fully describes
the responsibilities and the activities of the Audit Committee.

Employee Benefits and Compensation Committee:

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

Functions: The Compensation Committee administers Westamerica Bancorporation’s Amended and Restated
Stock Option Plan of 1995, Tax Deferred Savings and Retirement Plan, Deferred Profit Sharing Plan, Deferred
Compensation Plan, and the Westamerica Bancorporation Deferral Plan. It administers the Corporation’s
compensation programs and reviews and reports to the Board the compensation level for executive officers,
including the CEO, of the Corporation and its subsidiaries and determines that compensation plans are
balanced between financial results without motivation of excessive 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 does not have a charter as it is not required by NASDAQ rules. The
Compensation Committee has the authority to seek assistance from officers and employees of the Corporation
as well as external legal, accounting and other advisors. It has not retained outside consultants for compensation
advice, but can request assistance on an as-needed basis. It does not delegate authority to anyone outside of the
Compensation Committee. The Human Resources Department supports the Compensation Committee by
fulfilling certain administrative duties regarding the compensation programs.

Nominating Committee:

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

Functions: The Nominating Committee is governed by a written charter, which was amended in January 2010
and was attached as an exhibit to the Proxy Statement for the 2010 Annual Meeting of Shareholders. The
Nominating Committee screens and recommends qualified candidates for Board membership. This Committee
recommends a slate of nominees for each Annual Meeting. As part of that process, it evaluates and considers all
candidates submitted by shareholders in accordance with the Corporation’s bylaws, and considers each existing
Board member’s contributions. The Committee applies the same evaluation standards whether the candidate
was recommended by a shareholder or the Board.

While the Board does not have a formal diversity policy, it believes that the Board should broadly define

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

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

Nominations must include the following information:

(cid:129)  The principal occupation of the nominee; 
(cid:129)  The total number of shares of capital stock of the Corporation that the shareholder expects will be voted 
for the nominee;
(cid:129)  The name and address of the nominating shareholder; and
(cid:129)  The number of shares of capital stock of the Corporation owned by the nominating shareholder.

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

(cid:129)  Appropriate personal and professional attributes to meet the Corporation’s needs;
(cid:129)  Highest ethical standards and absolute personal integrity;
(cid:129)  Physical and mental ability to contribute effectively as a Director;
(cid:129)  Willingness and ability to participate actively in Board activities and deliberations;
(cid:129)  Ability to approach problems objectively, rationally and realistically;
(cid:129)  Ability to respond well and to function under pressure;
(cid:129)  Willingness to respect the confidences of the Board and the Corporation;
(cid:129)  Willingness to devote the time necessary to function effectively as a Board member;
(cid:129)  Possess independence necessary to make unbiased evaluation of Management performance;
(cid:129)  Be free of any conflict of interest that would violate applicable law or regulation or interfere with ability

(1) Non-employee Directors did not receive options or stock awards. During 2011, non-employee Directors of the Corporation each received an annual
retainer of $15,000. Each non-employee Director received $1,200 for each meeting of the Board attended and $600 for each Committee meeting attended.
The Chairman of each Committee received an additional $250 for each Committee meeting attended. All non-employee Directors are reimbursed for
expenses incurred in attending Board and Committee meetings. The Chairman of the Board, David L. Payne, is compensated as an employee and did not
receive any compensation as a Director. 

(2) The Deferred Compensation Plan allows non-employee Directors to defer some or all of their Director compensation with interest earnings credited on
deferred compensation accounts. The amount shown is the interest on nonqualified deferred compensation that exceeds 120% of the long- term Applicable
Federal Rate, with compounding, on all cash compensation deferred in 2011 and in previous years.

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

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

The executive compensation practices described below have been followed consistently for twenty  years. At the
2009 and 2011 Annual Meetings of Shareholders, a majority of our shareholders approved an advisory proposal
on the Corporation’s compensation of executives.

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:

(cid:129)  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.
(cid:129)  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 a
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.
(cid:129)  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.  

Establishing Incentive Levels, Determining Objectives and Measuring Performance

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

At the beginning of each calendar year, the Compensation Committee establishes annual corporate

performance objectives. In establishing corporate performance objectives, the Compensation Committee takes
into consideration the current operating environment for the commercial banking industry as well as internal
management policies and practices which would, in the Compensation Committee’s opinion, benefit the long-
term interests of the Corporation and its shareholders. Corporate performance measures include risk management
elements considered to be responsive to the impact 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, liquidity in capital markets, the demand for capital by
commercial enterprises and consumers, new financial products, competitive response to changing conditions
within the industry, trade balances, the changing values of real estate, currencies, commodities and other assets,
and other factors.

Management policies and practices the Board considers in establishing corporate performance objectives
include, but are not limited to, management of the Corporation’s balance sheet and product pricing in a manner
which will provide consistent sustainable growth in long-term financial results for shareholders, the type and
variety of financial products offered by the Corporation, adherence to internal controls, management of the credit
risk of Corporation’s loan and investment portfolios, the results of internal, regulatory and external audits, service

quality delivered to the Corporation’s customers, service quality of “back office” support departments provided to
those offices and departments directly delivering products and services to the Corporation’s customers,
maintenance of operating policies and procedures which remain appropriate for risk management in a dynamic
environment, timely and efficient integration of acquired companies, operational efficiencies, and capital
management practices.

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

In addition to establishing corporate performance objectives, the Compensation Committee also establishes

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

Upon the closure of each calendar year, the Compensation Committee reviews corporate, divisional, and

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

Stock Grants

Long-term stock grants may only be awarded under shareholder approved stock-based incentive compensation
plans. The Corporation’s Proxy Statement dated March 17, 2003, as filed with the SEC on that date, summarizes
the 2003 Amended Plan’s changes from the predecessor plan. Such changes included:

(cid:129)  disallowing re-pricing stock options for poor stock performance;
(cid:129)  limiting the number of shares that may be awarded; and
(cid:129)  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.

The 2003 Amended Plan allows four types of stock-based compensation awards:

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

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

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

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

Determination of Awards to Grant

In determining which type of stock-based compensation awards to grant, the Compensation Committee considers
the attributes of each form of incentive. Examples include the ability to motivate management to make decisions
based on the long-term interests of shareholders, the desire to compensate with shares rather than cash, and the tax
consequences of each type of award. The Compensation Committee retains the latitude to utilize all 
forms of incentives provided under the 2003 Amended Plan. In the current and preceding years, the
Compensation Committee has utilized NQSO and RPS based on the motivational aspects of stock price
appreciation, the settlement in shares rather than cash, and the preservation of tax deductions for the
Corporation. At February 27, 2012 the Corporation had no ISO or SAR awards outstanding.

Determination of Option Exercise Price

The 2003 Amended Plan also requires the exercise price of each NQSO or ISO to be no less than 
one hundred percent (100%) of the fair market value of the Corporation’s common stock on the date of grant.
As described above, the 2003 Amended Plan does not allow re-pricing stock options for poor stock price
performance.

Stock-based compensation awards are submitted by the Compensation Committee to the full Board of

Directors for review. As described above, these meetings have routinely occurred in January immediately following
the closure of the calendar year for which performance is measured for incentive compensation purposes. The
Compensation Committee meeting has routinely been held during the same week as the related Board of Directors
meeting. These January meetings follow by no more than ten business days the Corporation’s public disclosure of its
financial results for the preceding year. As a result, stock option grants are awarded, and the exercise price of such
grants are determined at a time when the Corporation has broadly disseminated its financial condition and current
operating results to the public. The Corporation’s outstanding stock option grants are dated, and related stock option
exercise prices are determined, on the January date the Compensation Committee meets to approve such grants.(1)

Long-Term Incentive Attributes

The Board of Directors has designated the Compensation Committee as the administrator of the 2003 Amended
Plan. The Compensation Committee reports to the Board the terms and conditions of stock option awards. In
carrying out this responsibility, the Compensation Committee designs such awards as long-term incentives. The
terms and conditions of currently outstanding awards include:

(cid:129)  NQSO vest one-third (1/3) on each anniversary of the grant date. As such, NQSO grants become fully
vested over a three-year period. NQSO grants expire on the tenth anniversary of the grant date. The
Corporation does not pay dividends on shares underlying NQSO grants until the optionee exercises the option
and the shares are outstanding on a dividend record date.
(cid:129)  RPS awards vest three years following the grant date, only if corporate performance objectives are achieved
over the three-year period. The Corporation does not pay dividends on RPS shares until vesting occurs and
shares awarded become outstanding on a dividend record date.

Compensation for the Chairman, President & CEO

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

As noted on page 27 of the proxy under the Pension Benefits Table, during 1997 the Corporation entered into

a nonqualified pension agreement (“Pension Agreement”) with Mr. Payne in consideration of Mr. Payne’s
agreement that RPS granted in 1995, 1996 and 1997 would be cancelled. In entering the Pension Agreement, the
Board of Directors considered the following:

(cid:129)  Mr. Payne had a significant beneficial interest in Corporation common stock, which was more than adequate
to continue to provide motivation for Mr. Payne to continue managing the Corporation in the best interests of
shareholders.
(cid:129)  In 1997, the Corporation had consummated its largest acquisition, with significant total asset growth of
approximately 51 percent. One of the Board’s objectives was to provide a compensation mechanism providing
retention features for Mr. Payne. Retention of Mr. Payne as President and Chief Executive Officer was desired
following the Corporation’s significant growth. The RPS shares surrendered for the Pension Agreement were
scheduled to vest on dates in 1998, 1999 and 2000, while the Pension Agreement was not fully vested until
December 31, 2002. Additionally, the 20-year certain pension provided under the Pension Agreement commences
upon Mr. Payne’s attainment of age 55. Mr. Payne was age 42 at the time of entering the Pension Agreement.
(cid:129)   The economic value of the surrendered RPS and the Pension Agreement were considered equivalent based
on actuarial assumptions.

Compensation Awarded to Named Executive Officers

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

________________
(1) 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.

     In structuring performance goals for the named executive officers, the Compensation Committee emphasizes
goals, which if achieved, will benefit the overall Corporation. As such, senior management level positions have
high relative weighting on corporate objectives, and divisional leadership positions also have significant weighting
on divisional objectives. The “target” cash incentive and the weighting of goals for the named executive officers for
2011 performance were as follows:

                                                “Target”                                                 Goal Weighting

     The Compensation Committee establishes corporate goals with the intent to balance current profitability with
long-term stability of the Corporation and its future earnings potential. The 2011 corporate performance goals
related to current year “profitability” included return on equity, return on assets and diluted earnings per share.
The performance goals designed to maintain the long-term stability of the Corporation include “quality” and
“control” components. The “quality” measures include loan portfolio quality measures (originated classified loans
and other real estate owned, originated non-performing loans and originated other real estate owned, and net loan
losses to average originated loans) and service quality measures (external service quality to customers and internal
service quality of support departments and branches). The “control” measures include non-interest expense to
revenues (efficiency ratio), the level of non-interest expenses, and internal audit results. By maintaining both
current year “profitability” goals and longer-term “quality” and “control” goals, Management has a disincentive to
maximize current earnings at the expense of longer-term results. 

For 2011, the Compensation Committee expected a highly uncertain operating environment given fragile
economic conditions following 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 2011 operating environment was generally characterized as follows:

(cid:129)  The economy grew at a level below economic potential. Inflation was not problematic and employment
remained very weak with relatively high unemployment. Real estate values did not recover from valuation
declines experienced during the recession. 
(cid:129)  The Federal Reserve continued to provide monetary stimulus through a variety of means including increasing
demand for longer-dated treasury bonds which caused longer-term interest rates to decline.
(cid:129)  The FDIC continued to take failed banks into receivership, although the number of banks on the FDIC
“problem list” began to decline. The Federal Deposit Insurance Corporation (“FDIC”) reported in the fourth
quarter 2011 that the Deposit Insurance Fund remained in a deficit position, causing insurance assessments 
to remain elevated.
(cid:129)  New regulations on financial institutions significantly curtailed long-standing sources of revenue.

(cid:129)  Interest rates on high-quality loans and investment securities remain extremely low, well below the yields on
the Company’s loan and investment portfolios. Competitive pricing of loans was fierce.

The Compensation Committee considered Management’s response to the current operating environment including:
(cid:129)  Management consistently maintained conservative loan underwriting practices to appropriately manage the
Company’s exposure to credit risk;
(cid:129)  Management maintained loan pricing at levels appropriate for longer-term profitability; 
(cid:129)  Management pursued fee income growth outside deposit based fees in response to new regulations;
(cid:129)  Management controlled operating costs in a manner to offset the effect of environmental pressures on revenues;
(cid:129)  Management maintained an “interest rate neutral” position with its assets, liabilities and capital. As such,
future changes in interest rates should not have a significant impact on revenue; and
(cid:129)  Adequate capital levels were maintained to accommodate growth opportunities. 

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

                                                                                                  Performance                        Adjusted Actual

     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% 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:

(cid:129) Managing the Company to satisfactory financial results including revenue stabilization, cost control, 
and risk management;
(cid:129) Developing merger and acquisition opportunities; 
(cid:129) Improving credit quality; 
(cid:129) Maintaining quality shareholder relations with effective communication;
(cid:129) Fostering effective sales and service activities throughout the Company; 
(cid:129) Effective internal control management to include regulatory examination and other audit results; and 
(cid:129) Following effective personnel practices including succession planning.

19

 
 
Based on individual performance against these goals, the Committee exercised its discretion and assigned 
Mr. Payne a composite corporate and individual performance level of 67%.

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

(cid:129) Adoption of new SEC reporting requirements and other enhancements to financial reporting;
(cid:129) Personnel recruiting and development; and 
(cid:129) Evaluation of shareholder communications.

Based on the Finance Division’s results, the Committee determined divisional performance to be 119%. 

In addition to daily management responsibilities, Mr. Thorson’s individual goals included:
(cid:129) Coordination of regulatory examinations;
(cid:129) Planning and forecasting of financial results;
(cid:129) Evaluation of new regulations; and 
(cid:129) Evaluation of regulatory capital. 

Based on individual performance against these goals, the Committee determined Mr. Thorson’s individual
performance to be 138%. In considering all elements of performance, the Committee exercised its discretion and
assigned Mr. Thorson a composite corporate, divisional and individual performance level of 142%.

In addition to routine on-going divisional responsibilities, Ms. Finger managed the Treasury Division toward
functional goals, which included:

(cid:129) Asset and liability risk management;
(cid:129) Management of investment portfolio activity;
(cid:129) Management of merchant credit card and trust operations including sales activities revenue levels, and expense
containment; and
(cid:129) Management of balance sheet, interest rate risk position, funding, and liquidity.

Based on the Treasury Division’s results, the Committee determined divisional performance to be 123%. 

In addition to daily management responsibilities, Ms. Finger’s individual goals included:

(cid:129) Management of the stock repurchase program;
(cid:129) Merger and acquisition due diligence; and
(cid:129) Management of any corporate litigation.

Based on individual performance against these goals, the Committee determined Ms. Finger’s individual
performance to be 134%. As a result, Ms. Finger’s composite corporate, divisional and individual performance
level was 119%.

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

(cid:129) Achievement of high-quality internal customer service delivery;
(cid:129) Cost control;
(cid:129) Management of significant information systems projects; and
(cid:129) Satisfactory regulatory and internal audit results.

RPS awards vest three years following the grant date, only if certain corporate performance objectives are achieved
over the three-year period. In January 2012, the Compensation Committee evaluated whether the three-year
corporate performance objectives were met for RPS awards granted in January 2009. The performance objectives
for the RPS granted in January 2009 included:

(cid:129) 3-year cumulative diluted earnings per share (EPS);
(cid:129) 3-year average of annual return on average total assets (ROA);
(cid:129) 3-year average of annual return on average shareholders’ equity relative to industry average ROE (ROE differential);
(cid:129) Ending non-performing assets to total assets (NPA); and
(cid:129) 3-year average of annual growth in revenues per share (RevPS growth).

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

(cid:129) 4 of 5 objectives reaching “threshold” performance level;
(cid:129) 3 of 5 objectives reaching “target” performance level; or
(cid:129) 2 of 5 objectives reaching “outstanding” performance level.

The goals and achieved results were:

                                            Threshold                     Target              Outstanding                          Result

executives the ability to defer compensation in excess of the annual limits imposed on the Corporation’s “401(k)”
plan. The Corporation believes these tax deferral programs enhance loyalty and motivate retention of executives.
These programs allow executives to defer cash pay and RPS shares upon vesting. The programs also allow
Directors to defer Director fees.

(cid:129) Cash pay deferred in the program accumulates in accounts in the names of the participating Directors and 
executives. The Corporation credits the balance of these accounts with interest using an interest rate that
approximates the crediting rate on corporate-owned life insurance policies, which finance the cash pay deferral
program. Deferrals and interest credits represent general obligations of the Corporation.
(cid:129) The common stock the Corporation issues to executives upon the vesting of RPS grants may be deferred 
into the program and deposited into a “Rabbi Trust.” Since these shares are outstanding shares of the
Corporation’s common stock, the Corporation pays dividends on these shares at the same rate paid to all
shareholders. The shares held in the “Rabbi Trust” are subject to claims by the Corporation’s creditors.

Employment Contracts

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

Compensation in the Event of a Change in Control

The banking industry has significant merger and acquisition activity. To promote retention of senior executives,
unvested NQSO and RPS grants contain a “change in control” provision, which trigger full vesting upon a change
in control. The Compensation Committee determined these provisions were appropriate in order to retain
executives to continue managing the Corporation after any “change in control” was announced through its
ultimate consummation. Since none of the named executive officers have entered employment contracts with the
Corporation, they serve in an “at-will” capacity and could terminate their employment at any time. The
Compensation Committee felt it would be in the best interests of shareholders to have a retention mechanism in
place to provide continuity of management during a “change in control” process. Further, the Committee expects
the named executive officers would be terminated by an acquiring institution rather than retained in a similar
functional capacity.

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

Other 

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

Board Compensation Committee Report

We, the Compensation Committee of the Board of Directors of the Corporation, 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 Corporation’s Annual Report on Form 10-K for the year ended December, 31, 2011.

(3) The amounts shown are non-equity incentive compensation only. No interest or other form of earnings was paid on the compensation.  

(4) The amounts include interest paid on deferred cash compensation to the extent the interest exceeds 120% of the long-term Applicable Federal Rates with
compounding. The Corporation has no defined benefit pension plan. Mr. Payne has a pension agreement, which is discussed under “Pension Benefits for 2011.”

(5) Each of the above-named executive officers received less than $10,000 of aggregate perquisites and personal benefits, except for Mr. Hansen who received 
a car allowance of $12,000. All other compensation includes Corporation contributions to defined contribution plans (401(k) and Profit Sharing), and
amounts added to taxable wages using IRS tables for the cost of providing group term life insurance coverage that is more than the cost of $50,000 of
coverage. It also includes the dollar value of the benefit to Mr. Payne for the portion of the premium payable by the Corporation with respect to a split dollar
life insurance policy (projected on an actuarial basis), and a bonus paid to Mr. Payne in the amount of his portion of the split dollar life insurance premium.

Based on the compensation disclosed in the Summary Compensation Table, approximately 33% of total

compensation comes from base salaries. See Compensation Discussion and Analysis for more details.

Non-Qualified Pension Agreement

$6,257,539

$511,950

During 1997, the Corporation entered into a nonqualified pension agreement with Mr. Payne in consideration of
Mr. Payne’s agreement that RPS awards granted in 1995, 1996 and 1997 would be cancelled.  In January 2000, the
Compensation Committee, based on the Corporation’s achievement of certain performance goals which had first
been established for Mr. Payne’s 1995, 1996 and 1997 RPS awards, determined Mr. Payne’s annual pension would
be $511,950. The pension commenced in 2010 at age 55 and will be paid to Mr. Payne for 20 years. 

The discount rate used to determine the present value is 4.60%, as used by the Corporation in determining
benefit obligations for its post-employment retirement benefits as of December 31, 2011. The obligation is an
unfunded general obligation of the Corporation.

(1) RPS shares deferred upon vesting in 2011 were disclosed as compensation in the Summary Compensation Table in 2008, the year of grant, and are
therefore excluded from the Summary Compensation Table for Fiscal Year 2011. Non-equity incentive plan compensation deferred in 2011 was earned in
2010 and disclosed as compensation in the Summary Compensation Table for 2010 and is therefore excluded from the Summary Compensation Table for
Fiscal Year 2011. In 2011, Mr. Robinson deferred $12,000 of salary earned in 2011 which is included in the Summary Compensation Table for Fiscal Year 2011.

(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 Summary Compensation Table for Fiscal Year 2011 on page 24 are as follows: Ms. Finger – $16,826; Messrs. Thorson – $20,393;
Robinson – $16,495; and Hansen – $14,124. 

(3) Includes dividends paid on deferred RPS shares.

(4) Aggregate balance of deferred compensation reported as compensation prior to 2011 is as follows: Ms. Finger — $ 2,280,648; Messrs. Thorson –
$1,084,213; Hansen – $1,286,128; and Robinson – $1,616,136.    

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 2011 was 6.00%. 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 ten 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 2003 Amended Plan as shareholder approval of a dissolution or
liquidation of the Corporation or a sale of substantially all of the Corporation’s assets to another corporation, 
or a tender offer for 5% or more of the Corporation’s outstanding common stock or a merger in which the
Corporation’s shareholders before the merger hold less than 50% of the voting power of the surviving corporation
after the merger.

In the event of a change in control, unvested NQSOs and RPS shares immediately vest. The value of in-the-
money options and RPS shares subject to accelerated vesting for each of the named executive officers is as follows:
Ms. Finger: $333,427; Messrs. Payne: $109,750; Thorson: $333,427; Robinson: $335,681; and Hansen: $300,351.
The value is computed by multiplying the difference between the market value on December 30, 2011, the last
business day of 2011, and the exercise price of each option by the number of shares subject to accelerated vesting.   

Under the Corporation’s Severance Payment Plan, executive officers receive six weeks pay for every year or
partial year of service up to a maximum of one year’s base salary (see Summary Compensation Table for Fiscal Year
2011 for annual base salary for all named executive officers). All named executive officers have met the service
requirement for one year’s base salary. Severance pay is paid in a lump sum or on a semi-monthly basis at the
discretion of the Corporation, subject to Section 409A of the Internal Revenue Code.

Certain Relationships and Related Party Transactions

In accordance with the Audit Committee Charter, the Audit Committee is responsible for reviewing and
approving or disapproving all related party transactions required to be disclosed by Item 404 of Regulation S-K for
potential conflicts of interest. Additionally, the Corporation’s Code of Conduct and Ethics provides rules that
restrict transactions with affiliated persons.  

Certain of the Directors, executive officers and their associates have had banking transactions with subsidiaries

of the Corporation in the ordinary course of business. With the exception of the Corporation’s Employee Loan
Program, all outstanding loans and commitments included in such transactions were made on substantially the
same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with
other persons not related to the Corporation, did not involve more than a normal risk of collectibility, and did not
present other favorable features. As part of the Employee Loan Program, all employees, including executive

officers, are eligible to receive mortgage loans with interest rates one percent (1%) below Westamerica Bank’s
prevailing interest rate at the time of loan origination. Westamerica Bank makes all loans to executive officers
under the Employee Loan Program in compliance with the applicable restrictions of Section 22(h) of the Federal
Reserve Act.  Messrs. Hansen, Payne and Thorson have mortgage loans through this Program. The largest
aggregate amount of principal during 2011 was $273,601, $496,363 and $369,669, respectively. The principal
amount outstanding at December 31, 2011 was $264,291, $478,837 and $353,908, respectively. The amount of
principal paid during 2011 was $9,311, $17,526, and $15,761, respectively. The amount of interest paid during
2011 was $5,759, $9,876 and $7,230, respectively. The rate of interest payable on the loan is 1.875%, 1.875%
and 1.875%, respectively. 

Mr. Hansen also has a $99,000 line of credit. The largest amount of principal outstanding during 2011 was
$83,375. The amount of principal paid during 2011 was $140,298 and the principal amount outstanding at
December 31, 2011 was $0.00. The amount of interest paid during 2011 was $1,676. The variable rate of interest
payable on the line of credit is Wall Street Journal Prime minus 0.5%

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

Background

The 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) required that
shareholders cast a non-binding advisory vote last year 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 last year’s vote on the
proposal to determine the frequency of future say-on-pay proposals was that shareholders should review executive
compensation annually. Therefore, Proposal 2 requests that shareholders again approve the compensation paid 
to our named executive officers. Last year 99% of the shares voting on this proposal voted to support our
corporation’s executive compensation strategy. 

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 Corporation’s 2003 Amended Plan to include the following changes:
(cid:129) Disallowing re-pricing stock options for poor stock performance;
(cid:129) Limiting the number of shares that may be awarded; and
(cid:129) 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.

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 Corporation’s proxy statement for the annual meeting of shareholders.”

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

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

PROPOSAL 3 -  APPROVE THE 2012 AMENDED AND RESTATED STOCK OPTION PLAN OF 1995

General

The Corporation’s Stock Option Plan of 1995 was adopted by the Board on January 26, 1995 and approved

by shareholders on April 25, 1995. The Amended and Restated Stock Option Plan of 1995 was approved by
shareholders on April 24, 2003 (the “2003 Amended Plan”). The Amended 2003 Plan will expire on April 24,
2013. Shareholders are being asked to further amend the 2003 Amended Plan by  approving the 2012 Amended
and Restated Stock Option Plan of 1995 (the “2012 Amended Plan”) that will, among other things, reduce the
number of shares available for future issuance from 4,307,593 to 1,500,000, extend the term of the plan to April
26, 2022, and amend the circumstances which define a “change of control” which results in full vesting of all stock
awards. The 2012 Amended Plan is subject to shareholder approval at the April 26, 2012 Annual Meeting of
Shareholders.  A summary of proposed changes is set forth below, followed by a summary description of the entire
2012 Amended Plan. The full text of the 2012 Amended Plan is attached to this proxy statement as Exhibit A.

Approval of the 2012 Amended Plan will allow Westamerica to continue to provide long-term incentives to

employees who are responsible for the success and growth of Westamerica, to further align the interests of
employees with the interests of the shareholders and to assist Westamerica in attracting and retaining employees 
of experience and outstanding ability.

Summary of Changes

Available Shares Limited. On January 1 of each plan year, the 2003 Amended Plan reserves shares outstanding
for issuance, in addition to unissued, cancelled, terminated or forfeited shares from previous years of the plan. The
2003 Amended Plan limits annual reserves for options to the least of (i) 2% of shares outstanding on January 1 of
each plan year, (ii) 675,000 shares, or (iii) a lesser amount as the Board may determine. The 2012 Amended Plan
eliminates the annual reservation of shares outstanding for issuance and reduces the current reserve of 4,307,593
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. The average annual grant of shares during 2009, 2010, and 2011
under the current plan has been approximately 291,000.

Plan Expiration Date. The 2003 Amended Plan expires April 24, 2013. The proposed 2012 Amended Plan
expires on April 26, 2022 after which shareholder approval is again required to extend the term or approve a new
stock option plan.

Full Vesting of Awards Upon a Change in Control. The 2003 Amended Plan states that Options and
Restricted Performance Shares shall immediately become exercisable in full and deemed fully vested, respectively,
in the event that either (a) the shareholders of the Corporation approve a dissolution or liquidation of the
Corporation or a sale of all or substantially all of the Corporation’s assets to another corporation, or (b) a tender
within the meaning of Section 14 of the Exchange Act is made for five percent (5%) or more of the Corporation’s
outstanding Common Stock by any person other than the Corporation or any of its Subsidiaries. 

The proposed 2012 Amended Plan states that Options and Restricted Performance Shares shall immediately
become exercisable in full and deemed fully vested, respectively, in the event of a “Change of Control,” defined as:
(i) The acquisition by any individual, entity, or group (other than a trustee or other fiduciary holding securities
under an employee benefit plan of the Corporation or a corporation owned directly or indirectly by the shareholders
of the Corporation in substantially the same proportions as their ownership of Common Stock of the Corporation)
of Beneficial Ownership of twenty-five percent (25%) or more of the combined voting power of the Corporation’s
then outstanding securities with respect to the election of Directors of the Corporation; (ii) The consummation of a
reorganization, merger, or consolidation of the Corporation or sale or other disposition of all or substantially all of the
assets of the Corporation; excluding, however, a corporate transaction pursuant to which all or substantially all of the
individuals or entities who are the Beneficial Owners of the Corporation immediately prior to the corporate
transaction will beneficially own, directly or indirectly, more than fifty percent (50%) of the outstanding shares of
common stock of the resulting entity and of the combined voting power of the outstanding securities entitled to vote
for the election of directors of such entity; or (iii) Individuals who, as of the Effective Date, constitute the Board (the
“Incumbent Board”) cease for any reason to constitute at least a majority of such Board; provided, that any individual
who becomes a Director of the Corporation subsequent to the Effective Date, whose election, or nomination for
election by the Corporation’s shareholders, was approved by the vote of at least a majority of the Directors then
comprising the Incumbent Board shall be deemed a member of the Incumbent Board; and provided further, that 
any individual who was initially elected as a Director of the Corporation as a result of an actual or threatened election
contest, as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Securities Exchange Act of
1934, or any other actual or threatened solicitation of proxies or consents by or on behalf of any Person other than the
Board shall not be deemed a member of the Incumbent Board.

No Repricing for Poor Stock Performance. The 2012 Amended Plan preserves Article IV paragraph 3 of the
2003 Amended Plan which states that the exercise price of outstanding options may not be decreased and no
option may be cancelled or forfeited and immediately re-granted to affect the same result, and preserves Article XII
of the 2003 Amended Plan which allows the price of options to be adjusted to reflect stock splits and other
corporate actions.

Compensation Committee Composition. The 2012 Amended Plan preserves Article IV paragraph 1 of 
the 2003 Amended Plan which states that the composition of the Committee shall 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.

Summary of the 2012 Amended Plan

Shares Available for Issuance. The proposed 2012 Amended and Restated Stock Option Plan of 1995 provides
for awards in the form of restricted performance shares, stock options, stock appreciation rights (“SARs”), or any
combination thereof. To date, no awards have been made under the 2012 Amended Plan or have been committed.
The shares of common stock available for issuance under the 2003 Amended Plan as of February 27, 2012 are
4,307,593; shareholder approval of the 2012 Amended Plan will reduce the shares of Common Stock available for
issuance to 1,500,000. In addition, awards outstanding under prior plans as of April 26, 2012 (approximately
2,385,284 shares) that expire or are cancelled, forfeited or terminated before being exercised shall become available
for future awards under the 2012 Amended Plan. In If any restricted performance shares, options or SARs granted
under the 2012 Amended Plan are forfeited, or if options or SARs terminate for any other reason prior to exercise,
then the underlying shares of Common Stock shall again become available for awards. If SARs are exercised
for cash, the number of shares underlying such awards shall become available for further awards. Notwithstanding
the foregoing, no more than 500,000 shares of Common Stock shall be available for the grant of incentive stock
options (“ISOs”) over the term of the Plan. The shares available for award hereunder, the grants and the grant
limits may be subject to adjustment for stock splits and certain other events.

Administration and Eligibility. The 2012 Amended Plan is to be administered by a committee of the Board
whose composition will enable the 2012 Amended Plan to qualify (i) under Rule 16b-3 of the Exchange Act with
regard to the grant of awards to persons who are subject to Section 16 of the Exchange Act and (ii) under Section
162(m) of the Internal Revenue Code (Code) with regard to any award intended to qualify as performance based
compensation. The Committee selects the employees of the Corporation or any subsidiary who will receive
awards, determines the size of the award and establishes the vesting or other conditions. All employees of the
Corporation (or any subsidiary of the Corporation) are eligible to participate in the Plan. As of January 1, 2012,
34 employees were qualified by the Compensation Committee to participate in the 2003 Amended Plan. As of
February 27, 2012, the fair market value of a Company common share was $48.03.

Payment. In general, no payment will be required upon receipt of an award.

Restricted Performance Shares. A restricted performance share (“RPS”) is an unfunded bookkeeping entry
representing the equivalent of one share of Common Stock, and it is nontransferable prior to the holder’s death. 
A holder of restricted performance shares has no voting rights or other privileges as a shareholder.

Restricted performance shares, when vested, will be settled by distributing shares of Common Stock. The number

of shares of Common Stock distributed in settlement of restricted performance shares may be smaller than the
number of restricted performance shares granted, depending upon the attainment of performance objectives. These
performance conditions may be established pursuant to Code Section 162(m) and many include one or more of the
following:  (i) earnings, (ii) diluted earnings per share, (iii) revenue and revenue per diluted share, (iv) expenses, (v)
share price, (vi) return on equity, (vii) return on equity relative to the average return on equity for similarly sized
institutions, (viii) return on assets, (ix) return on assets relative to the average return on assets for similarly sized
institutions, (x) efficiency ratio (operating expenses divided by operating revenues), (xi) net loan losses as a percentage
of average loans outstanding, (xii) nonperforming assets, and (xiii) nonperforming assets as a percentage of total assets,
and may be calculated in accordance with the formula established for a performance period. A performance period
shall be any period not exceeding 36 months, as determined by the Committee in its sole discretion. No key employee
shall receive a grant for more than 25,000 restricted performance shares with respect to a performance period.

Stock Options. Options may include nonstatutory stock options (NQSOs) as well as ISOs intended to qualify
for special tax treatment. No optionee shall be granted options during any calendar year in excess of 300,000

shares of Common Stock. The term of an option cannot exceed ten years, and the exercise price of an option must
be equal to or greater than the fair market value of the Common Stock on the date of grant. The exercise price of
an option may be paid in any lawful form permitted by the Committee, including (without limitation) the surrender
of shares of Common Stock already owned by the optionee. The Plan also allows the optionee to pay the exercise
price of an option by giving exercise/sale directions. If exercise/sale directions are given, a number of option shares
sufficient to pay the exercise price and any withholding taxes is issued directly to a securities broker selected by the
Corporation who, in turn, sells these shares in the open market. The broker remits to the Corporation the proceeds
from the sale of these shares, and the optionee receives the remaining option shares or cash.

Stock Appreciation Rights. A SAR permits the participant to elect to receive any appreciation in the value of the
underlying stock from the Corporation in cash. No optionee shall be granted SARs during any calendar year in
excess of 300,000 shares of the Common Stock of the Corporation. The amount payable on exercise of a SAR is
measured by the difference between the market value of the underlying stock at exercise and the exercise price.

Vesting Conditions. As noted above, the Committee determines the number of restricted performance shares,
stock options or SARs to be included in the award as well as the vesting and other conditions. The vesting
conditions may be based on the employee’s service, his or her individual performance, the Corporation’s
performance, or other criteria. Vesting conditions for RPS will be based on the Corporation’s, individual’s or other
performance. It is anticipated that the vesting conditions for NQSOs, ISOs and SARs generally will be based on
the employee’s service after the date of grant. Vesting may be accelerated in the event of the employee’s death,
disability or retirement and will be fully accelerated in the event of a change in control with respect to the
Corporation. For purposes of the 2012 Amended Plan, a change in control includes: (i) the acquisition by any
individual, entity, or group (other than a trustee or other fiduciary holding securities under an employee benefit
plan of the Company or a corporation owned directly or indirectly by the shareholders of the Company in
substantially the same proportions as their ownership of Stock of the Company) of Beneficial Ownership of
twenty-five percent (25%) or more of the combined voting power of the Company’s then outstanding securities
with respect to the election of Directors of the Company; (ii) the consummation of a reorganization, merger, or
consolidation of the Company or sale or other disposition of all or substantially all of the assets of the Company;
excluding, however, a corporate transaction pursuant to which all or substantially all of the individuals or entities
who are the Beneficial Owners of the Company immediately prior to the corporate transaction will beneficially
own, directly or indirectly, more than fifty percent (50%) of the outstanding shares of common stock of the
resulting entity and of the combined voting power of the outstanding securities entitled to vote for the election of
directors of such entity; or (iii) individuals who, as of the Effective Date, constitute the Board (the “Incumbent
Board”) cease for any reason to constitute at least a majority of such Board; provided, that any individual who
becomes a Director of the Company subsequent to the Effective Date, whose election, or nomination for election
by the Company’s shareholders, was approved by the vote of at least a majority of the Directors then comprising
the Incumbent Board shall be deemed a member of the Incumbent Board; and provided further, that any
individual who was initially elected as a Director of the Company as a result of an actual or threatened election
contest, as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act, or any
other actual or threatened solicitation of proxies or consents by or on behalf of any Person other than the Board
shall not be deemed a member of the Incumbent Board.

Nontransferability of Awards. Unless the individual award agreement provides otherwise, with respect to
awards other than incentive stock options, awards granted under the Plan may not be sold, transferred, pledged,
assigned, or otherwise alienated or hypothecated, other than by will or by the applicable laws of descent and distribution.

Modifications. The Committee is authorized, within the provisions of the Plan, to amend the terms of

outstanding restricted performance shares, to modify or extend outstanding options or SARs, or to exchange 
new options for outstanding options; provided, however, the Committee will not reprice options by canceling and
immediately granting options with a lower price.

Federal Income Tax Consequences

The following discussion of the federal income tax consequences of the ISOs and NQSOs under the Plan is intended
to be a summary of applicable federal law. State and local tax consequences may differ. Because the federal income tax
rules governing options and related payments are complex and subject to frequent change, optionees are advised to
consult their tax advisors prior to exercise of options or dispositions of stock acquired pursuant to option exercise.

ISOs and NQSOs are treated differently for federal income tax purposes. ISOs are intended to comply with the

requirements of Section 422 of the Code. NQSOs need not comply with such requirements. An optionee is not
taxed on the grant or exercise of an ISO. The difference between the exercise price and the fair market value 
of the shares on the exercise date will, however, be a preference item for purposes of the alternative minimum tax.
If an optionee holds the shares acquired upon exercise of an ISO for at least two years following grant and at least
one year following exercise, the optionee’s gain, if any, upon a subsequent disposition of such shares is long-term
capital gain. The measure of the gain is the difference between the proceeds received on disposition and the optionee’s
basis in the shares (which generally equals the exercise price). If an optionee disposes of stock acquired pursuant to
exercise of an ISO before satisfying the one- and two-year holding periods described above, the optionee will recognize
both ordinary income and capital gain in the year of disposition. The amount of the ordinary income will be the
lesser of (i) the amount realized on disposition less the optionee’s adjusted basis in the stock (usually the exercise price)
or (ii) the difference between the fair market value of the stock on the exercise date and the exercise price. The balance
of the consideration received on such a disposition will be long-term capital gain if the stock had been held for at least
one year following exercise of the ISO. The Corporation is not entitled to an income tax deduction on the grant or
exercise of an ISO or on the optionee’s disposition of the shares after satisfying the holding period requirement
described above. If the holding periods are not satisfied, the Corporation will be entitled to a deduction in the year
the optionee disposes of the shares, in an amount equal to the ordinary income recognized by the optionee.

An optionee is not taxed on the grant of a NQSO. On exercise, however, the optionee recognizes ordinary income

equal to the difference between the exercise price and the fair market value of the shares on the date of exercise. The
Corporation is entitled to an income tax deduction in the year of exercise in the amount recognized by the optionee
as ordinary income. Any gain on subsequent disposition of the shares is long-term capital gain if the shares are held
for at least one year following exercise. The Corporation does not receive a deduction for this gain.

An optionee is not taxed on the grant of RPS. Upon receipt of vested shares, however, the optionee recognizes

ordinary income equal to the fair market value of the shares on the date of distribution. The Corporation is
entitled to an income tax deduction in the year of distribution in the amount recognized by the optionee as
ordinary income. Any gain on subsequent disposition of the shares is long-term capital gain if the shares are held
for at least one year following exercise. The Corporation does not receive a deduction for this gain.

An optionee is not taxed on the grant of SARs. Upon receipt of cash settlement, however, the optionee
recognizes ordinary income equal to cash received. The Corporation is entitled to an income tax deduction in the
year of settlement in the amount recognized by the optionee as ordinary income.

New Plan Benefits

The Committee has full discretion to determine the number and amount of options to be granted to employees
under the Plan, subject to the Plan’s grant limits. Therefore, the benefits and amounts that will be received by the
Chief Executive Officer and the four other most highly compensated executive officers, the executive officers as 
a group and all other employees are not determinable. Details on stock options granted during the last three years 
to the Chief Executive Officer and the four other most highly compensated executive officers are presented in the
table entitled Summary Compensation Table.

____________________

(1) The information in the above table is as of the end of the 2011 fiscal year.

(2) Under the current Amended and Restated Stock Plan of 1995 (the “2003 Amended Plan”), the maximum aggregate number of shares for which options 
or other rights may be granted in any calendar year will be increased by the least of (i) two percent (2%) of the share of common stock outstanding as of the
last day of the prior fiscal year, (ii) 675,000 shares, subject to adjustment pursuant to Article XII, or (iii) such lesser amount as the Board may determine. Any
shares that have been reserved but not issued under Awards during any calendar year remain available for grant during any subsequent calendar year. Awards
that expire or are cancelled, forfeited or terminated before being exercised again become available for future awards under the plan. If shareholders approve
the proposed 2012 Amended and Restated Stock Option Plan of 1995:

(cid:129) the number of shares remaining available for future issuance under equity compensation plans will be reduced to 1,500,000 (plus additional shares 
that become available as described below) as of April 26, 2012, which amount will be increased only by the affirmative vote of shareholders;
(cid:129) unexercised and non-vested awards outstanding under prior plans as of April 26, 2012 (approximately 2,385,284 shares) will remain in force; 
and if they expire before being exercised or are cancelled, forfeited, or terminated, those shares will become available (in addition to the base number 
of 1,500,000 shares) for future awards under the 2012 Amended Plan;
(cid:129) awards granted after April 26, 2012 under the 2012 Amended Plan that expire or are cancelled, forfeited or terminated before being exercised 
shall again become available for future awards under the plan; and
(cid:129) the 2012 Amended and Restated Stock Option Plan of 1995 will remain in effect until April 26, 2022.

(3) Includes 50,220 restricted performance shares (RPS) that were outstanding on December 31, 2011 under Westamerica’s Amended and Restated Stock
Option Plan of 1995. RPS awards currently outstanding vest upon achievement of predetermined performance goals at the end of the third year following
the date of grant. RPS awards do not have an exercise price; their value is dependent upon the achievement of certain performance goals and may be settled
for common stock on a one-for-one or cash basis. Accordingly, the RPS awards have been disregarded for purposes of computing the weighted-average
exercise price.

Required Approval

The affirmative vote of the holders of a majority of the shares of Common Stock present and voting at the Meeting,
but not less than a majority of a quorum, is required to approve the Plan. Properly executed proxies received by the
Corporation which have not indicated any vote on the Plan will be voted FOR approval of the Plan.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE APPROVAL OF THE PLAN.

PROPOSAL 4 – RATIFY SELECTION OF INDEPENDENT AUDITOR

The Audit Committee has approved the selection of the firm of KPMG LLP to serve as independent auditors 
for 2012 to examine the consolidated financial statements of the Corporation. Action by the shareholders is not
required by law in the appointment of independent auditors, but their appointment is submitted by the Audit
Committee and the Board of Directors in order to give the shareholders an opportunity to present their views. 
If the proposal is approved, the Audit Committee, in its discretion, may direct the appointment of different
independent auditors at any time during the year if it determines that such a change would be in the best interests

independent auditors. 

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

Audit Fees
     The aggregate fees billed to the Corporation by KPMG with respect to services performed for fiscal 2011 and
2010 are as follows:

Tax fees                                                                            –                                        –
All other fees                                                                    –                                        –
                                                                         ________                         ________
                                                                           $710,000                          $735,000
__________________

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

Pre-Approval Policies and Procedures

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

The Audit Committee must pre-approve all auditing services and permitted non-audit services by its

independent auditors and the fees to be paid by the Corporation for these services, except for those fees qualifying
for the “de minimis exception” which provides that the pre-approval requirement for certain non-audit services
may be waived if certain expressed standards and requirements are satisfied prior to completion of the audit under
certain conditions. This exception requires that the aggregate amount of all such services provided constitutes no
more than five percent of the total amount of revenue paid to the audit firm by the Corporation during the fiscal
year in which the services are provided. At the time of the engagement, the Corporation did not recognize such
services to be non-audit services, and such services are promptly brought to the attention of the Audit Committee
and approved prior to the completion of the audit by the Audit Committee. During fiscal year 2011, 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
pre-approvals of non-audit services and fees. In such event, the decisions of the member or members of the Committee
regarding pre-approvals are presented to the full Audit Committee at its next meeting. The Audit Committee
pre-approved 100% of all services performed on behalf of the Corporation by KPMG during fiscal year 2011.

AUDIT COMMITTEE REPORT

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

The Audit Committee is composed of four Directors who are neither officers nor employees of the

Corporation, and who meet the NASDAQ independence requirements for Audit Committee members. The Audit
Committee selects, appoints and retains the Corporation’s independent auditors and is responsible for their
compensation and oversight.

In performing its functions, the Audit Committee acts only in an oversight capacity and necessarily relies on

the work and assurances of the Corporation’s management, which has the primary responsibility for financial
statements and reports, and of the independent auditors. The auditors express an opinion on the conformity of 
the Corporation’s annual financial statements to generally accepted accounting principles. In fulfilling its oversight
responsibilities, the Audit Committee reviewed the audited consolidated financial statements for the fiscal year
2011 and discussed them with Management and with KPMG, the Corporation’s independent auditors.

Management represented to the Audit Committee that the Corporation’s consolidated financial statements
were prepared in accordance with generally accepted accounting principles. Management also represented that it
performed an assessment of the effectiveness of internal control over financial reporting as of December 31, 2011,
and that internal control over financial reporting was effective. The Audit Committee discussed with the auditors
matters required to be discussed by Statement on Auditing Standards No. 114 (The Auditor’s Communication
with Those Charged with Governance) as amended, including the auditors’ judgment about the quality as well as
the acceptability of the Corporation’s accounting principles, as applied in its financial reporting.

The auditors also provided to the Audit Committee the written disclosures and the letter from the independent

auditors required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit
Committees). The Audit Committee discussed with auditors the firm’s independence.

Based on the Audit Committee’s discussion with Management and the independent auditors, the Audit
Committee’s review of the representations of Management and the report of the independent auditors to the Audit
Committee, the Audit Committee recommended that the Board of Directors include the audited consolidated
financial statements in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2011 
for filing with the SEC.

Meeting, the notice must be received by the Corporate Secretary a reasonable time before we begin to print and
mail our Proxy Statement. All such proposals must meet the requirements of Rule 14a-8 under the Exchange Act.

In order for business, other than a shareholder proposal submitted for the Corporation’s Proxy Statement, to 
be properly brought before next year’s Annual Meeting by a shareholder, the shareholder must give timely written
notice to the Secretary of the Corporation. To be timely, written notice must be received by the Secretary of the
Corporation at least 45 days before the anniversary of the day our Proxy Statement was mailed to shareholders 
in connection with the previous year’s Annual Meeting or January 27, 2013, for the 2013 Annual Meeting. If the
date of the Annual Meeting is changed by more than 30 days, the deadline is a reasonable time before we begin 
to mail our Proxy Statement. A shareholder’s notice must set forth a brief description of the proposed business, 
the name and residence address of the shareholder, the number of shares of the Corporation’s common stock that
the shareholder owns and any material interest the shareholder has in the proposed business.

Westamerica reserves the right to reject, to rule out of order, or to take other appropriate action with respect to

any proposal that does not comply with these and other applicable legal requirements.

SHAREHOLDER COMMUNICATION TO BOARD OF DIRECTORS

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

OTHER MATTERS

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

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

                                                                                         BY ORDER OF THE BOARD OF DIRECTORS 

                                                                                         Kris Irvine

II.  PURPOSE

It is the purpose of this amended and restated Plan to provide a means whereby those Employees who have
responsibilities for the successful administration and management of Westamerica Bancorporation and whose
present and potential contributions to the success of Westamerica Bancorporation are of importance to the
Corporation can acquire a proprietary interest in the Corporation thereby providing an incentive for continuing
beneficial services to the Corporation.

III. SHARES SUBJECT TO THE PLAN

The aggregate number of shares reserved for Awards under the Plan prior to this amendment and restatement equals
4,307,593. Upon the approval by the shareholders of the Corporation of the Plan, the aggregate number of shares
reserved for Awards under the Plan will be 1,500,000 (plus additional shares that become available as described in the
following sentence). If any Pre-Existing Award expires, is cancelled, forfeited or terminates for any reason before being
exercised, then the shares of Common Stock subject to such Award shall become available for future Awards under the
Plan in addition to the base number of 1,500,000 shares. If any Award expires, is cancelled, forfeited or terminates for
any reason before being exercised, then the shares of Common Stock subject to such Award shall again become available
for future Awards under the Plan. In addition, when SARs are surrendered for cash, the shares of Common Stock
subject to such SARs shall be restored to the share pool available for future Awards. Notwithstanding the foregoing,
no more than 500,000 shares of Common Stock shall be available for the grant of ISOs over the term of the Plan.

IV.  ADMINISTRATION OF THE PLAN

1.  Committee Procedures. The Committee shall be designated by the Board and shall have such membership
composition which enables (1) the Plan to qualify under Rule 16b-3 issued under the Securities Exchange Act 
of 1934 (the “Exchange Act”) with regard to the grant of Awards to persons who are subject to Section 16 of the
Exchange Act and (2) any Award intended to qualify as “performance based compensation” within the meaning of
Section 162(m) of the Code and the regulations thereunder, to so qualify. The Committee may hold meetings at such
times and places as it shall determine. The acts of a majority of the Committee members present at meetings at which a
quorum exists, or acts reduced to or approved in writing by all Committee members, shall be valid acts of the Committee. 

2.  Committee Responsibilities. Subject to the provisions of the Plan, the Committee shall have full authority
and discretion to take the following actions:

(a) To interpret the Plan and to apply its provisions;
(b) To adopt, amend or rescind rules, procedures and forms relating to the Plan;
(c) To authorize any person to execute, on behalf of the Corporation, any instrument required to carry 

out the purposes of the Plan;

(d) To determine when Awards are to be granted under the Plan;
(e) To select the recipients of Awards and grant Awards;
(f) To determine the number of shares to be subject to each Award;
(g) To prescribe the terms and conditions of each Award, including (without limitation) the exercise 
price, the vesting or duration of the Award (including accelerating the vesting of the Award), to 
determine whether an Option is to be classified as an ISO or NQSO, and to specify the provisions 
of the Award Agreement relating to such Award;

(h) To amend any outstanding Award Agreement, subject to applicable legal restrictions and to the 

consent of the Employee who entered into such agreement;

(i) To prescribe the consideration for the grant of each Award under the Plan and to determine the 

sufficiency of such consideration;

(j) To determine the disposition of each Award under the Plan in the event of an Employee’s divorce or 

dissolution of marriage;

(k) To determine whether Options or other Awards under the Plan will be granted in replacement of 

other grants under an incentive or other compensation plan of an acquired business;

(l) To correct any defect, supply any omission, or reconcile any inconsistency in the Plan, or any 

Option or Award Agreement; and

(m) To take any other actions deemed necessary or advisable for the administration of the Plan.

Subject to the requirements of applicable law, the Committee may designate persons other than members of
the Committee to carry out its responsibilities and may prescribe such conditions and limitations as it may deem
appropriate, except that the Committee may not delegate its authority (1) with regard to the selection for
participation of or the granting of  Awards under the Plan to persons subject to Section 16 of the Exchange Act
and (2) to preclude any Award intended to qualify as “performance based compensation” within the meaning of
Section 162(m) of the Code and the regulations thereunder, from so qualifying. All decisions, interpretations and
other actions of the Committee shall be final and binding on all Award recipients, and all persons deriving their
rights from an Award recipient. No member of the Committee shall be liable for any action that he has taken or
has failed to take in good faith with respect to the Plan or any Award.

3. Modification, Extension and Renewal of Awards. Within the limitations of the Plan, the Committee
may modify, extend or renew outstanding Awards. Notwithstanding anything herein to the contrary, the
exercise price of outstanding Options may not be decreased (except pursuant to Article XII) and Options 
may not be cancelled or forfeited and immediately re-granted to effect the same result.  The foregoing
notwithstanding, no modification of an Award shall, without the consent of the Employee, impair his 
rights or increase his obligations under such Award.

4.  Limitations on SARs and Options. No Employee shall be granted SARs or Options during any calendar year
in excess of 300,000 shares of Common Stock.

IVA.  STOCK APPRECIATION RIGHTS

1.  The Committee shall also have the authority to grant SARs on such terms and conditions as it deems appropriate,
consistent with the purposes of the Plan. On surrender of each SAR, the SAR holder shall receive a cash payment
equal to the difference obtained by subtracting (1) the Fair Market Value of one share of Common Stock on the
surrender date from (2) the Fair Market Value of one share of Common Stock on the date the SAR was granted.

2.  The Committee shall from time to time determine which Employees shall be granted SARs under the Plan, the
terms thereof, and the number of SARs to be granted.

3.  The term of a SAR shall be determined by the Committee but in no event shall the term extend beyond ten
years from the date of the grant. SARs may be exercisable in full or in installments, as the Committee determines
at the date of grant.

4.  The provisions of this Plan applicable to Options shall apply to SARs where the context so permits and as
necessary to carry out the purposes of the Plan, as determined by the Committee in its sole discretion.

1.  The persons who shall be eligible to receive Awards shall be such Employees as the Committee, in its sole
discretion, shall select from time to time during the duration of the Plan.

V.  ELIGIBLE EMPLOYEES

2.  A Director of the Corporation or of a Subsidiary shall not be eligible to receive an Award unless such director is
also an Employee.

VI.  OPTION EXERCISE PRICE

The exercise price of each Option granted hereunder shall be determined by the Committee, but in no event shall
be less than one hundred percent (100%) of the Fair Market Value of the Common Stock at the time such Option
is granted, as determined by the Committee. Such exercise price shall be adjusted as provided in Article XII hereof.

VII.  PAYMENT OF OPTION EXERCISE PRICE

The exercise price with respect to the Common Stock being purchased by an Optionee upon the exercise of an
Option in whole or in part shall be paid in full to the Corporation either (i) in cash, (ii) by delivery of Common
Stock owned by the Optionee for such duration as may be specified by the Committee and duly endorsed for
transfer to the Corporation, or (iii) a combination of cash and Common Stock. Shares of Common Stock owned
by the Optionee and delivered to the Corporation in payment of all or part of the exercise price of an Option shall
be valued for this purpose at one hundred percent (100%) of the Fair Market Value of such Common Stock on
the day of such exercise, as determined by the Committee. Optionees electing to pay all or part of the exercise
price of an Option by delivery of Common Stock shall not be entitled to receive fractional shares to the extent, if
any, that the Fair Market Value of such Common Stock exceeds such exercise price, but instead shall be entitled to
cash in lieu thereof. To the extent that an Option Agreement so provides, payment may be made all or in part by
delivery (on a form approved by the Committee) of an irrevocable direction to the Optionee’s securities broker to
sell shares of Common Stock and to deliver all or part of the sale proceeds to the Corporation in payment of the
aggregate exercise price and any taxes. 

VIII.  TERMS AND EXERCISE OF OPTIONS

1.  The term of each Option granted hereunder shall be determined by the Committee, but in no event shall
the term of an ISO be greater than ten (10) years from the date of grant or such shorter term as may be fixed
by the Committee.

2.  Each Option Agreement shall specify the date when all or any installment of the Option is to become
exercisable. The Option Agreement shall also specify the term of the Option. Subject to the preceding two
sentences, the Committee at its sole discretion shall determine when all or any installment of an Option is to
become exercisable and when an Option is to expire.

3.  Notwithstanding the preceding paragraph, all outstanding Options shall immediately become exercisable in full
in the event of a Change in Control.

IX.  TERMINATION OF EMPLOYMENT

Each Award Agreement shall set forth the extent to which the Grantee shall have the right to exercise the Award

following termination of employment with Westamerica Bancorporation, and the right to exercise the Award of
any executors or administrators of the Grantee’s estate or any person who has acquired such Award(s) directly from
the Grantee by bequest or inheritance. Such provisions shall be determined in the sole discretion of the
Committee, need not be uniform among all Awards issued pursuant to the Plan, and may reflect distinctions
based on the reasons for termination of employment.

X.  NON-TRANSFERABILITY

Unless the Award Agreement provides otherwise with respect to Awards other than ISOs, no Award may be
transferred by a Grantee otherwise than by will or the laws of descent and distribution, and each Award may be
exercised, during the Grantee’s lifetime, only by the Grantee.

XI.  RESTRICTED PERFORMANCE SHARE GRANTS

1.  The Committee shall also have the authority to award Restricted Performance Share Grants pursuant to
agreements with such terms and conditions as it deems appropriate, consistent with the purposes of the Plan. In
determining whether or not to award a Grant to a particular individual, the Committee shall consider the performance
of Westamerica Bancorporation during the prior year and such individual’s performance during such year.

2.  Such key Employees as shall be selected by the Committee in its sole discretion (hereinafter the “Grant
Participants”) shall be eligible to receive Grants hereunder.

3.  The provisions of this Plan applicable to Options shall apply to Grants where the context so permits and as
necessary to carry out the purposes of the Plan, as determined by the Committee in its sole discretion.

4.  A Grant shall become vested, in full or in installments, upon satisfaction of the conditions set forth in the
Grant Agreement. The Committee in its sole discretion shall determine when all or any installment of a Grant 
is to vest and when a Grant is to expire or be terminated. Grants shall be made in the form of stock units based on
the Fair Market Value of a share of Common Stock, and such Grants shall be settled in the form of cash or shares
of Common Stock or any combination of both, and may be made in a lump sum or installments. The actual
number of Grants eligible for settlement may be larger or smaller than the number included in the Grant
Agreement, based on predetermined performance factors.  Such performance factors may be established pursuant
to the requirements of Section 162(m) of the Code and may include one or more of the following: (i) earnings, 
(ii) diluted earnings per share, (iii) revenue and revenue per diluted share, (iv) expenses, (v) share price, (vi) return on
equity, (vii) return on equity relative to the average return on equity for similarly sized institutions, (viii) return on
assets, (ix) return on assets relative to the average return on assets for similarly sized institutions, (x) efficiency ratio
(operating expenses divided by operating revenues), (xi) net loan losses as a percentage of average loans outstanding, 
(xii) nonperforming assets and (xiii) non performing assets as a percentage of total assets, and may be calculated in
accordance with the formula established for a “performance period.” A performance period shall be any period not
exceeding 36 months, as determined by the Committee in its sole discretion. No key employee shall receive a
Grant for more than 25,000 stock units with respect to a performance period. Before any shares of Common
Stock and/or cash are paid with respect to a performance period that is intended to comply with Section 162(m)
of the Code, the Committee shall certify in writing that the performance factors for such period have been satisfied.

5.  All outstanding Grants shall immediately be deemed to be fully vested and the appropriate number of shares 
of Common Stock shall be issued to the Grantees in the event of a Change in Control.

XII.  ADJUSTMENTS UPON CHANGES IN STOCK

Subject to all of the restrictions, conditions and performance criteria otherwise applicable to an Award, in the
event (a) of an increase or decrease in the number of shares of Common Stock, (b) that shares of Common Stock
shall be changed into or exchanged for a different number or kinds of shares of stock or other securities of the
Corporation or of another corporation, whether through merger, consolidation, reorganization, recapitalization 
or otherwise, or (c) a stock dividend is paid to holders of Common Stock or a stock split or reverse stock split is
effected, then the Committee shall conclusively determine the appropriate adjustments, if any, to (i) the number
and type of shares or other securities appropriated for purposes of the Plan pursuant to Article III hereof but not
yet covered by Awards, (ii) the number and type of shares or other securities subject to each Award then
outstanding, (iii) the exercise price of each Award then outstanding, (iv) the maximum number and type of shares
or other securities that may be made subject to ISOs and (v) the maximum number of and type of shares or other
securities with respect to which Awards may be granted during any calendar year under the Plan, in each case, so
that such adjustments do not constitute a modification within the meaning of Section 424 of the Code and only

to the extent otherwise permitted under Sections 422 and 424 of the Code or, in the case of Awards intended to
qualify as “performance based compensation” within the meaning of Section 162(m) of the Code in such a
manner to not adversely affect such intended treatment.

In the event of a Change in Control, then all outstanding Awards shall become fully vested and

immediately exercisable.

XIII.  RIGHTS AS A GRANTEE, SHAREHOLDER, OR EMPLOYEE

Nothing contained in the Plan, in any resolution adopted by the Board, in any approval by the shareholders 
of the Corporation or in any action taken by the Committee shall vest in any individual employed by the
Corporation or by any Subsidiary the right to receive any Award under the Plan.  No person shall acquire any
rights as contemplated by or pursuant to the Plan unless and until a written Option Agreement, Award Agreement,
or Grant Agreement shall have been duly executed on behalf of the Corporation by such officer and officers 
as the Committee shall designate for such purpose, delivered to the Grantee named therein, and executed by him.  
No person shall have any rights as a shareholder with respect to any shares covered by an Award until the date of 
the issuance of a stock certificate to the Grantee for such shares.  Nothing contained in the Plan shall confer, and 
each Option Agreement, Award Agreement, or Grant Agreement shall expressly provide that the granting of an
Award does not confer on any Employee any right to or guarantee of continued employment by Westamerica
Bancorporation, or in any way limit the right of Westamerica Bancorporation to terminate the employment of any
Employee at any time and for any reason.

Notwithstanding the express provisions of the Plan, any Award may be granted on such additional or more
restrictive terms as the Committee shall deem advisable consistent with the Plan. 

XIV.  OTHER PROVISIONS

XV.  REGISTRATION AND RESALE

The Plan, the shares of Common Stock subject thereto, and the Awards granted thereunder may, in the discretion
of the Board, be registered under the Securities Act of 1933, as amended, or under the securities laws of any state.
As a condition to the grant of any Award under the Plan or the issuance of shares of Common Stock upon the
exercise thereof, the Committee may require that the Employee agree to comply with such provisions of Federal
and State securities laws as may be applicable to such grant or issuance or the sale of shares acquired thereby and
deliver to the Corporation a written agreement in form and substance satisfactory to the Corporation and its
counsel implementing such agreement.

XVI.  EFFECTIVE DATE, TERM AND SHAREHOLDER APPROVAL

The Plan shall become effective upon approval by the shareholders of the Corporation and shall remain in effect
until April 26, 2022, unless it is sooner terminated by the Board. In any event the Plan shall terminate no later
than April 26, 2022, and no Awards may be granted under the Plan thereafter.

XVII.  AMENDMENT OF PLAN

FORWARD-LOOKING STATEMENTS 

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

These forward-looking statements are based on Management’s current knowledge and belief and include information concerning 
the Company’s possible or assumed future financial condition and results of operations. A number of factors, some of which are 
beyond the Company’s ability to predict or control, could cause future results to differ materially from those contemplated. These
factors include but are not limited to (1) the length and severity of current and potential future 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 data processing system failures 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.

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.

In  August,  2000,  the  Company  acquired  First  Counties  Bank.  In  June  of  2002  the  Company  acquired  Kerman  State  Bank.  On 
March 1, 2005, the Company acquired Redwood Empire Bancorp, the parent company of National Bank of the Redwoods (NBR). 
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”).  The  Bank  and  the  FDIC  entered  loss  sharing  agreements  regarding  future  losses  incurred  on 
acquired  loans  and  foreclosed  loan  collateral.  Under  the  terms  of  the  loss  sharing  agreements,  the  FDIC  absorbs  80  percent  of 
losses and is entitled to 80 percent of loss recoveries on the first $269 million of losses, and absorbs 95 percent of losses and is 
entitled to 95 percent of loss recoveries on losses exceeding $269 million. The term for loss sharing on residential real estate loans 
is ten years, while the term for loss sharing on non-residential real estate loans is five years in respect to losses and eight years in 
respect to loss recoveries. The County acquisition was accounted for under the acquisition method of accounting in accordance 
with FASB ASC 805, Business Combinations. On August 20, 2010, Westamerica Bank acquired assets and assumed liabilities of 
the  former  Sonoma  Valley  Bank  (“Sonoma”)  from  the  FDIC.  The  acquired  assets  and  assumed  liabilities  were  measured  at 
estimated fair values, as required by FASB ASC 805, Business Combinations.  

Management made significant estimates and exercised significant judgment in accounting for these 2009 and 2010 acquisitions. 
Management judgmentally measured loan fair values based on loan file reviews (including borrower financial statements and tax 
returns), appraised collateral values, expected cash flows, and historical loss factors. Repossessed loan collateral was primarily
valued based upon appraised collateral values. The Bank also recorded identifiable intangible assets representing the value of the 
core  deposit  customer  bases  based  on  Management’s  evaluation  of  the  cost  of  such  deposits  relative  to  alternative  funding 
sources. In determining the value of the identifiable intangible assets, Management used significant estimates including average
lives  of  depository  accounts,  future  interest  rate  levels,  the  cost  of  servicing  various  depository  products,  and  other  significant 
estimates. Management used quoted market prices to determine the fair value of investment securities, FHLB advances and other 
borrowings  which  were  purchased  and  assumed.  See  Note  2  of  the  Notes  to  Consolidated  Financial  Statements  for  additional 
information regarding the Sonoma acquisition. 

At  December  31,  2011,  the  Company  had  consolidated  assets  of  approximately  $5.0  billion,  deposits  of  approximately  $4.2 
billion  and  shareholders’  equity  of  approximately  $558.6  million.  The  Company  and  its  subsidiaries  employed  961  full-time 
equivalent staff as of December 31, 2011. 

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 are also available free of charge from the Company, as well as the Company’s director,

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 California
Commissioner of Financial Institutions (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 Financial Institutions (“DFI”), and the
Federal Reserve. 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. 

California law permits a state-chartered bank to invest in the stock and securities of other corporations, subject to a state-chartered 
bank receiving either general authorization or, depending on the amount of the proposed investment, specific authorization from
the Commissioner. 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, will: 

(cid:1)

(cid:1)

Centralize responsibility for consumer financial protection by creating a new agency, the Consumer Financial Protection 
Bureau, responsible for implementing, examining and enforcing compliance with federal consumer financial laws. 
Restrict  the  preemption  of  state  law  by  federal  law  and  disallow  subsidiaries  and  affiliates  of  national  banks  from 
availing themselves of such preemption. 

(cid:1) Apply the same leverage and risk-based capital requirements that apply to insured depository institutions to most bank 

(cid:1)

(cid:1)

(cid:1)

(cid:1)

(cid:1)

holding companies. 
Require  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. 
Change the assessment base for federal deposit insurance from the amount of insured deposits to consolidated assets less 
tangible capital, eliminate the ceiling on the size of the Deposit Insurance Fund ("DIF") and increase the floor of the size 
of the DIF. 
Impose  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. 
Require  large,  publicly  traded  bank  holding  companies  to  create  a  risk  committee  responsible  for  the  oversight  of 
enterprise risk management. 
Implement  corporate  governance  revisions,  including  with  regard  to  executive  compensation  and  proxy  access  by 
shareholders, that apply to all public companies, not just financial institutions. 

(cid:1) Make permanent the $250 thousand limit for federal deposit insurance and provide unlimited federal deposit insurance 
until December 31, 2012 for non-interest bearing demand transaction accounts at all insured depository institutions. 
Repeal the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions 
to pay interest on business transaction and other accounts. 

(cid:1)

(cid:1) Amend 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  will  take  effect  over  several  years,  making  it  difficult  to 
anticipate the overall financial impact on the Company, its customers or the financial industry more generally. Provisions in the
legislation  that  affect  the  payment  of  interest  on  demand  deposits  and  interchange  fees  may  increase  the  costs  associated  with 
deposits as well as place limitations on certain revenues those deposits may generate.

Capital Standards

The federal banking agencies have risk-based capital adequacy guidelines intended to provide a measure of capital adequacy that
reflects  the  degree  of  risk  associated  with  a  banking  organization’s  operations  for  both  transactions  resulting  in  assets  being
recognized on the balance sheet as assets, and the extension of credit facilities such as letters of credit and recourse arrangements, 
which  are  recorded  as  off  balance  sheet  items.  Under  these  guidelines,  nominal  dollar  amounts  of  assets  and  credit  equivalent 
amounts of off balance sheet items are multiplied by one of several risk adjustment percentages, which range from 0% for assets
with  low  credit  risk,  such  as  certain  U.S.  government  securities,  to  100%  for  assets  with  relatively  higher  credit  risk,  such  as
certain loans. A banking organization’s risk-based capital ratios  are obtained by dividing its qualifying capital by its total risk-
adjusted assets and off balance sheet items. 

The federal banking agencies take into consideration concentrations of credit risk and risks from nontraditional activities, as well 
as  an  institution’s  ability  to  manage  those  risks,  when  determining  the  adequacy  of  an  institution’s  capital.  This  evaluation  is
made as a part of the institution’s regular safety and soundness examination. The federal banking agencies also consider interest
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,  2011,  the  Company’s  and  the  Bank’s  respective  ratios  exceeded  applicable  regulatory  requirements.  See 
Note 10 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. 

The Company anticipates changes to the regulatory capital framework due to the Dodd-Frank Act, which requires 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.

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 and supervisory rating 
("CAMELS rating"). 

In December 2008, the FDIC issued a final rule that raised the then current assessment rates uniformly by 7 basis points for the
first  quarter  of  2009  assessment  (basis  points  representing  cents  per  $100  of  assessable  deposits).  In  February  2009,  the  FDIC 
issued final rules to amend a restoration plan for the DIF, change the risk-based assessment system and set new assessment rates
beginning in the second quarter of 2009. The initial base assessment rates ranged from 12 to 45 basis points, on an annualized 
basis. After the effect of potential base-rate adjustments, total base assessment rates range from 7 to 77.5 basis points. 

In  May  2009,  the  FDIC  issued  a  final  rule  which  levied  a  special  assessment  applicable  to  all  insured  depository  institutions 
totaling 5 basis points of each institution's total assets less Tier 1 capital as of June 30, 2009, not to exceed 10 basis points of 
domestic deposits. The special assessment was part of the FDIC's efforts to rebuild the DIF. 

In  November  2009,  the  FDIC  issued  a  rule  that  required  all  insured  depository  institutions,  with  limited  exceptions,  to  prepay 
their estimated quarterly risk-based assessments for the fourth quarter of 2009 and for all of 2010, 2011 and 2012. The FDIC also
adopted  a  uniform  three-basis  point  increase  in  assessment  rates  effective  on  January  1,  2011;  however,  as  further  discussed 
below, the FDIC has elected to forego this increase under a new DIF restoration plan adopted in October 2010. 

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. Under the new restoration plan, the FDIC will forego the uniform three-basis point
increase in initial assessment rates scheduled to take place on January 1, 2011 and maintain the current schedule of assessment
rates for all depository institutions. 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  November  2010,  the  FDIC  issued  a  final  rule  to  implement  provisions  of  the  Dodd-Frank  Act  that  provide  for  temporary 
unlimited  coverage  for  noninterest-bearing  transaction  accounts.  The  separate  coverage  for  non-interest-bearing  transaction 
accounts became effective on December 31, 2010 and terminates on December 31, 2012. 

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. 

Financial Privacy Legislation and Customer Information Security

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

U.S.A. PATRIOT Act

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

Sarbanes-Oxley Act of 2002

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

Sarbanes-Oxley includes very specific additional disclosure requirements and corporate governance rules, required the SEC and 
securities exchanges to adopt extensive additional disclosure, corporate governance and other related rules and mandates further

studies of certain issues. Sarbanes-Oxley represents significant federal involvement in matters traditionally left to state regulatory 
systems, such as the regulation of the accounting profession, and to state corporate law, such as the relationship between a board
of directors and management and between a board of directors and its committees and public company shareholders. Sarbanes-
Oxley addresses, among other matters: (i) independent audit committees for reporting companies whose securities are listed on 
national  exchanges  or  automated  quotation  systems  (the  “Exchanges”)  and  expanded  duties  and  responsibilities  for  audit 
committees;  (ii)  certification  of  financial  statements  by  the  chief  executive  officer  and  the  chief  financial  officer;  (iii)  the
forfeiture of  bonuses  or other  incentive-based  compensation  and  profits from  the  sale of  an  issuer’s securities by  directors  and
senior officers in the twelve month period following initial publication of any financial statements that later require restatement; 
(iv) a prohibition on insider trading during pension plan black out 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 which 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 compared to 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. 

Current market developments may adversely affect the Company’s industry, business and results of operations. 

Declines in the housing market during recent years, with falling home prices and increasing foreclosures and unemployment, have
resulted in significant write-downs of asset values by financial institutions, including government-sponsored entities and major
commercial and investment banks. These write-downs caused many financial institutions to seek additional capital, to merge with
larger  and  stronger  institutions  and,  in  some  cases,  to fail.  During  the  recent  financial  crisis  and  recession,  liquidity  within  the 
financial system was challenged due to institutions evaluating counter-party risk, margin requirements rose, and other liquidity
reducing  activities  and  actions.  While  liquidity  has  generally  returned  to  the  United  States  financial  system,  a  recurrence  of 
economic  weakness  or  asset  valuation  declines  could  reduce  domestic  liquidity  levels.  Further,  global  economic  and  financial 
difficulties, including within Europe, could reduce liquidity in the United States. The Company has no direct operating exposure
to  European  sovereign  debt;  however,  the  Company  clears  daily  transactions  through  large  domestic  banks  which  have  global 
operations and exposure. Any resulting lack of available credit, volatility in the financial markets and reduced business activity 
could materially and adversely affect the Company’s business, financial condition and results of operations.  

The soundness 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 28.2 million shares of common stock were outstanding at December 31, 2011. Pursuant to its stock option plans, at
December 31, 2011, the Company had outstanding options for 2.3 million shares of common stock, of which 1.8 million were 
currently  exercisable.  As  of  December  31,  2011,  4.1  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,  2011,  approximately  1.4  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, 2011, real estate served as the principal source of collateral with respect to approximately 56% 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  currently  weak  following  a  severe  recession.  Much  of  the  California  real 
estate market has experienced a decline in values of varying degrees. This decline is having 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. Economic conditions in 
California  are  subject  to  various  uncertainties  at  this  time,  including  the  decline  in  construction  and  real  estate  sectors,  the
California  state  government’s  budgetary  difficulties  and  continuing  fiscal  difficulties.  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.

Most of the properties of the Company are located in California. Also, most of the real and personal properties which currently
secure  some  of  the  Company’s  loans  are  located  in  California.  California  is  a  state  which  is  prone  to  earthquakes,  brush  fires,
flooding, drought and other natural disasters. In addition to possibly sustaining damage to its own properties, if there is a major
earthquake, flood, 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:  
(cid:1)
(cid:1)
(cid:1)

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 of investment securities; 
an impairment of life insurance policies owned by the Company; 
an impairment of real estate owned by the Company. 

(cid:1)
(cid:1)
(cid:1)

Current market conditions have also led to the failure or merger of a number of financial institutions. Financial institution failures 
or  near-failures  have  resulted  in  further  losses  as  a  consequence  of  defaults  on  securities  issued  by  them  and  defaults  under 
contracts entered into with such entities as counterparties. Weak economic conditions can significantly weaken the strength and
liquidity of financial institutions. 

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

Overall,  during  2010  and  2011,  the  business  environment  has  been  adverse  for  many  households,  businesses  and  government 
entities in the United States, including California. There can be no assurance that these conditions will improve in the near term. 
Such 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. 

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 accounting charges that could have a material adverse effect on the 
Company’s net income and capital levels. 

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. 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 which 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. The rule had a mandatory compliance date of 
July  1,  2010  for  new  accounts  and  August  15,  2010  for  existing  accounts.  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. 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.  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. 

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 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. Recent economic conditions have increased bank failures, in which case the 
FDIC  takes  control  of  failed  banks  and  ensures  payment  of  deposits  up  to  insured  limits  using  the  resources  of  the  Deposit 
Insurance  Fund.  In  such  case,  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. 

The  FRB  has  been  providing  vast  amounts  of  liquidity  into  the  banking  system  due  to  current  economic  and  capital  market 
conditions. A reduction in the FRB’s activities or capacity could reduce liquidity in the markets, thereby increasing funding costs 
to the Bank or reducing the availability of funds to the Bank to finance its existing operations.

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  to  conduct  its  business.  Any  failure,  interruption  or 
breach  in  security  of  these  systems  could  result  in  failures  or  disruptions  in  the  Company’s  accounting,  customer  relationship 
management and other systems. Communication and information systems failures can result from a variety of risks including, but 
not  limited  to,  telecommunication  line  integrity,  weather,  terrorist  acts,  natural  disasters,  accidental  disasters,  unauthorized
breaches of security systems, and other events. There can be 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. 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. 

The Company may have underestimated losses on purchased loans.   

On February 6, 2009, the Bank acquired approximately $1.2 billion in loans and repossessed loan collateral of the former County
Bank  from the FDIC as its receiver. On August 20, 2010, the Bank acquired approximately $217 million in loans and repossessed 
loan collateral of the former Sonoma Valley Bank from the FDIC as its receiver. These purchased assets had suffered substantial
deterioration  at  the  respective  acquisition  dates,  and  the  Company  can  provide  no  assurance  that  they  will  not  continue  to 
deteriorate  now  that  they  are  the  Bank’s  assets.  If  Management’s  estimates  of  purchased  asset  fair  values  as  of  the  acquisition
dates  are  higher  than  ultimate  cash  flows,  the  recorded  carrying  amount  of  the  assets  may  need  to  be  reduced  with  a 
corresponding charge to earnings, net of FDIC loss indemnification on former County Bank assets.

ITEM 2. PROPERTIES

Branch Offices and Facilities

Westamerica  Bank  is  engaged  in  the  banking  business  through  95  branch  offices  in  21  counties  in  Northern  and  Central 
California. WAB believes all of its offices are constructed and equipped to meet prescribed security requirements. 

The Company owns 33 branch office locations and one administrative facility and leases 74 facilities. Most of the leases contain
multiple renewal options and provisions for rental increases, principally for changes in the cost of living index, and for changes in 
other operating costs such as property taxes and maintenance. 

ITEM 3. LEGAL PROCEEDINGS

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

As of January 31, 2012, there were approximately 7,000 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, and 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.” As of December 31, 2011, $166 million was allowable for payment of dividends by the 
Company to its shareholders, under applicable laws and regulations. 

The notes to the consolidated financial statements included in this report contain additional information regarding the Company’s
capital levels, 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.

As discussed in Note 9 to the consolidated financial statements, in December 1986, the Company declared a dividend distribution 
of one common share purchase right (the “Right”) for each outstanding share of common stock. The Rights expired on December 
31, 2009.  

On February 13, 2009, the Company issued a warrant to purchase 246,640 shares of its common stock at an exercise price of 
$50.92 per share with an expiration date of February 13, 2019. The warrant remained outstanding as of December 31, 2011. 

Stock performance 

The following chart compares the cumulative return on the Company’s stock during the ten years ended December 31, 2011 with 
the  cumulative  return  on  the  S&P  500  composite  stock  index  and  NASDAQ’S  Bank  Index.  The  comparison  assumes  $100 
invested in each on December 31, 2001 and reinvestment of all dividends.

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

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

The  following  discussion  addresses  information  pertaining  to  the  financial  condition  and  results  of  operations  of  Westamerica 
Bancorporation and subsidiaries (the “Company”) that may not be otherwise apparent from a review of the consolidated financial 
statements and related footnotes. It should be read in conjunction with those statements and notes found on pages 47 through 88,
as well as with the other information presented throughout the Report. 

Critical Accounting Policies

The Company’s consolidated financial statements are prepared in accordance with accounting principles generally accepted in the
United States 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  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 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  a  sample  of  securities  between  more  than  one  third-party  source.  When  third-party  information  is  not  available, 
valuation adjustments are estimated in good faith by Management. 

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 and 
purchased loan accounting to be the accounting areas 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.  

Acquisitions 

As described in Note 2, Westamerica Bank (“Bank”) acquired assets and assumed liabilities of the former Sonoma Valley Bank 
(“Sonoma”) on August 20, 2010 from the Federal Deposit Insurance Corporation (“FDIC”).  

On February 6, 2009, the Bank acquired assets and assumed liabilities of the former County Bank (“County”) from the FDIC. The 
Bank acquired approximately $1.62 billion assets and assumed approximately $1.58 billion liabilities. The Bank and the FDIC 
entered loss sharing agreements regarding future losses incurred on acquired loans and foreclosed loan collateral. Under the terms 
of the loss sharing agreements, the FDIC absorbs 80 percent of losses and is entitled to 80 percent of loss recoveries on the first
$269 million of losses, and absorbs 95 percent of losses and is entitled to 95 percent of loss recoveries on losses exceeding $269 
million. The loss sharing agreement on residential real estate loans expires February 6, 2019 and the loss-sharing agreement on
non-residential real estate loans expires February 6, 2014 as to losses and February 6, 2017 as to loss recoveries. 

In both acquisitions, the acquired assets and assumed liabilities were measured at estimated fair values, as required by FASB ASC
805,  Business Combinations.  Management  made  significant  estimates  and  exercised  significant  judgment  in  accounting  for  the 
acquisition.  Management  judgmentally  measured  loan  fair  values  based  on  loan  file  reviews  (including  borrower  financial 
statements  and  tax  returns),  appraised  collateral  values,  expected  cash  flows,  and  historical  loss  factors.  Repossessed  loan 
collateral  was  primarily  valued  based  upon  appraised  collateral  values.  The  Bank  also  recorded  identifiable  intangible  assets 
representing the value of the core deposit customer bases based on an evaluation of the cost of such deposits relative to alternative

funding sources. In determining the value of the identifiable intangible asset, Management used significant estimates including
average  lives  of  depository  accounts,  future  interest  rate  levels,  the  cost  of  servicing  various  depository  products,  future  FDIC 
insurance  assessments,  and  other  significant  estimates.  Management  used  quoted  market  prices  to  determine  the  fair  value  of 
investment securities, FHLB advances and other borrowings. 

Net Income

For 2011, the Company reported net income applicable to common equity of $87.9 million or $3.06 diluted earnings per common 
share (“EPS”), compared with net income applicable to common equity of $94.6 million or $3.21 EPS, for 2010. The 2011 results 
included $2.1 million  in  litigation  settlement accruals  which  decreased net  income  by  $1.2  million and  expenses  related  to  the 
integration of the former Sonoma Valley Bank (“Sonoma”) of $393 thousand after tax, equivalent to $0.06 diluted earnings per 
common share. The 2010 results included a $178 thousand gain on the acquisition of Sonoma Valley Bank.

Fully taxable equivalent (FTE)  

Comparing  2011  to  2010,  net  income  applicable  to  common  equity  decreased  $6.7  million  or  7.1%,  due  to  lower  net  interest 
income (FTE), lower noninterest income and higher noninterest expense, partially offset by a decrease in the income tax provision 
(FTE). The lower net interest income (FTE) was mainly 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 rates paid on interest-bearing liabilities. The 
provision for loan losses was unchanged, reflecting Management's evaluation of losses inherent in the loan portfolio not covered
by  loss-sharing  agreements  with  the  FDIC  and  purchased  loan  credit-default  discounts.  Noninterest  income  decreased  $1.4 
million largely due to lower service charges on deposit accounts. Noninterest expense increased $531 thousand mostly due to the
$2.1 million settlement accrual, offset by lower personnel costs and deposit insurance assessments. 

Comparing 2010 to 2009, net income applicable to common equity decreased $26.9 million, primarily due to a $48.8 million gain 
on  acquisition  in  2009,  lower  net  interest  income  (FTE)  and  higher  provision  for  loan  losses,  partially  offset  by  decreases  in 
noninterest expense and income tax provision (FTE) and the elimination of preferred stock dividends and discount accretion. The
lower  net  interest  income  (FTE)  was  primarily  caused  by  a  lower  volume  of  average  interest  earning  assets,  lower  yields  on 
investments and higher rates paid on borrowings, partially offset by higher yields on loans, lower average balances of interest-
bearing  liabilities  and  lower  rates  paid  on  interest-bearing  deposits.  The  provision  for  loan  losses  increased  $700  thousand, 
reflecting Management's assessment of losses inherent in the loan portfolio not covered by loss-sharing agreements with the FDIC
and  purchased  loan  credit-default  discounts.  Noninterest  income  decreased  $50.6  million  largely  due  to  a  $48.8  million 
acquisition  gain  in  2009.  Noninterest  expense  declined  $13.6  million  primarily  due  to  decreases  in  personnel,  occupancy  and 
equipment  expenses  reflecting  the  integration  of  the  acquired  County  operations  and  lower  FDIC  insurance  assessments.  The 
income tax provision (FTE) decreased $22.3 million. Net income applicable to common equity in 2009 reflected $4.0 million in 
preferred stock dividends and discount accretion.

Net Interest and Fee Income

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.  Net  interest  and  fee  income 
(FTE) in 2011 decreased $7.8 million or 3.4% from 2010, to $218.9 million. Comparing 2010 to 2009, net interest and fee income 
(FTE) decreased $15.5 million or 6.4% to $226.7 million.

Comparing 2011 with 2010, net interest and fee income (FTE) decreased $7.8 million or 3.4%, primarily due to a lower average 
volume of loans (down $217 million) and lower yields on interest earning assets (down 0.33%), partially offset by higher average
balances of investments ($236 million) and lower rates paid on interest-bearing liabilities (down 0.16%). 

Yields on interest-earning assets have declined due to relatively low interest rates prevailing in the market. Economic conditions, 
competitive pricing and deleveraging by businesses and individuals have reduced loan volumes, placing greater reliance on lower-
yielding investment securities. Rates on interest-bearing deposits and borrowings have declined to offset some of the decline in
asset yields. 

In Management's judgment, economic conditions and competitive pricing create a cautious view toward commercial lending, and 
economic pressure on consumers has reduced demand for automobile and other consumer loans. As a result, the Company has not 
taken an aggressive posture relative to loan portfolio growth. 

At December 31, 2011, purchased FDIC covered loans represented 21 percent of the Company’s loan portfolio. Under the terms 
of the FDIC loss-sharing agreements, the FDIC is obligated to reimburse the Bank 80 percent of loan interest income foregone on
covered loans. Such reimbursements are limited to the lesser of 90 days contractual interest or actual unpaid contractual interest at 
the time a principal loss is recognized in respect to the underlying loan. 

In 2011, interest and fee income (FTE) was down $12.3 million or 5.1% from 2010. The decrease resulted from a lower average 
volume of loans and lower yields on interest earning assets, partially offset by higher average balances of investments. A lower
average balance of the loan portfolio was mostly attributable to decreases in average balances of taxable commercial loans (down
$99  million),  commercial  real  estate  loans  (down  $46  million),  residential  real  estate  loans  (down  $45  million),  tax-exempt 
commercial  loans  (down  $19  million)  and  construction  loans  (down  $11  million).  The  average  investment  portfolio  increased 
mostly due to higher average balances of municipal securities (up $91 million), U.S. government sponsored entity obligations (up
$80 million), and corporate securities (up $61 million).  

The  average  yield  on  earning  assets  for  2011  was  5.52%  compared  with  5.85%  in  2010.  The  loan  portfolio  yield  for  2011 
decreased 0.14% compared with 2010 primarily due to lower yields on consumer loans (down 0.58%), residential real estate loans 
(down 0.43%), tax-exempt commercial loans (down 0.15%) and commercial real estate loans (down 0.04%), partially offset by 
increases in yields on construction loans (up 2.12%) and taxable commercial loans (up 0.06%). The higher yield on construction 
loans  in  2011  was  attributable  to  higher  interest  receipts  on  construction  loans  on  nonaccrual  status.  The  investment  portfolio
yield  declined from  5.13%  in  2010  to 4.60%  in  2011  mainly  due  to  decreases  in  yields  on  collateralized  mortgage  obligations 
(down 1.23%), residential mortgage-backed securities (down 0.23%) and municipal securities (down 0.20%), partially offset by a 
0.39% increase in yields on corporate securities which contain floating interest rate structures. 

Comparing 2011 with 2010, interest expense declined $4.5 million or 34.7%, due to lower rates paid on interest-bearing liabilities 
and  a  shift  from  higher  costing  term  repurchase  agreements,  time  deposits  less  than  $100  thousand  to  low-cost  checking  and 
savings accounts. Higher average balances of preferred money market savings (up $48 million), money market savings (up $43 
million),  money  market  checking  accounts  (up  $31  million),  regular  savings  (up  $27  million)  and  Federal  Home  Loan  Bank 
advances (up $7 million) were partially offset by lower average balances of short-term borrowed funds (down $94 million), time 
deposits  less  than  $100  thousand  (down $45  million),  time  deposits $100  thousand or more  (down $15  million)  and  long-term

debt (down $4 million). Lower average balances of short-term borrowed funds were attributable to repayment of the $100 million 
term repurchase agreement in December of 2010. Lower average balances of long-term debt were attributable to the redemption 
of a $10 million subordinated note. 

Rates paid on interest-bearing liabilities averaged 0.29% in 2011 compared with 0.45% in 2010 mainly due to lower rates on time
deposits  over  $100  thousand  (down  0.19%),  money  market  savings  (down  0.15%),  preferred  money  market  savings  (down 
0.27%),  short-term  borrowed  funds  (down  0.74%),  and  debt  financing  and  notes  payable  (down  2.78%),  partially  offset  by  a 
0.18% increase in rates on time deposits less than $100 thousand. Rates on short-term borrowed funds decreased as the Company 
repaid  the  $100  million  term  repurchase  agreement  in  December  of  2010.  Rates  on  debt  financing  payable  declined  due  to 
adjustments to the premium amortization on a $10 million subordinated note, which the Company redeemed in August 2011. 

In 2010, net interest income (FTE) decreased from 2009 primarily due to a lower volume of average interest earning assets (down
$378 million) and lower yields on investments (down 0.29%), partially offset by higher yields on loans (up 0.12%), lower average
balances of interest-bearing liabilities (down $287 million) and lower rates paid on interest-bearing deposits (down 0.2%). 

Comparing 2010 with 2009, interest and fee income (FTE) was down $22.1 million or 8.4%. The decrease resulted from a lower 
volume  of  average  interest  earning  assets  and  lower  yields  on  investment  securities,  partially  offset  by  higher  yields  on  loans.
Average interest earning assets decreased $378 million or 8.5% in 2010 compared with 2009 due to a $273 million decrease in 
average loans and a $105 million decrease in average investments. The decrease in the average balance of the loan portfolio was
attributable to decreases in average balances of taxable commercial loans (down $92 million), residential real estate loans (down
$75  million),  indirect  automobile  loans  (down  $50  million),  commercial  real  estate  loans  (down  $38  million),  tax-exempt 
commercial  loans  (down  $20  million)  and  construction  loans  (down  $11  million).  The  average  investment  portfolio  decreased 
$105 million largely due to declines in average balances of residential collateralized mortgage obligations (down $87 million),
residential  mortgage  backed  securities  (down  $41  million)  and  municipal  securities  (down  $31  million),  partially  offset  by 
increases  in  average  balances  of  $34  million  of  corporate  securities  and  $20  million  of  U.S.  government  sponsored  entity 
obligations. 

The average yield on interest earning assets in 2010 was 5.85%, unchanged from 2009. The loan portfolio yield in 2010 compared 
with 2009 period was higher by 0.12%, due to increases in yields on taxable commercial loans (up 0.58%) and construction loans 
(up 1.36%), partially offset by a 0.35% decrease in yields on residential real estate loans. The investment portfolio yield decreased 
from  5.42%  in  2009  to  5.13%  in  2010  as  maturities  and  paydowns  on  higher  yielding  portfolio  securities  were  replaced  with 
securities  bearing  lower  yields.  Yields  on  U.S.  government  sponsored  entity  obligations  decreased  2.7%.  Yields  on  municipal 
securities and U.S. Treasuries declined 0.08% and 2.24%, respectively. 

Comparing 2010 with 2009, interest expense declined $6.5 million or 33.7%, primarily due to lower average balances of interest-
bearing liabilities and lower rates on interest-bearing deposits. The Company’s average checking and savings deposits represented
77% of total deposits in 2010 compared with 74% in 2009. As a result, the Company’s reliance on higher-costing time deposits 
was  reduced.  Average  interest-bearing  liabilities  in  2010  fell  by  $287  million  from  2009  mainly  due  to  decreases  in  average 
balances  of  federal  funds  purchased  (down  $108  million),  FHLB  advances  (down  $45  million),  time  deposits  less  than  $100 
thousand (down $100 million), time deposits $100 thousand or more (down $57 million) and money market checking accounts 
(down $14 million), partially offset by increases in the average balance of money market savings (up $24 million) and regular 
savings (up $16 million). Rates paid on interest-bearing liabilities averaged 0.45% in 2010 compared with 0.62% in 2009. The 
average rate paid on interest-bearing deposits declined 0.2% to 0.34% in 2010 compared with 2009 mainly due to lower rates on 
time  deposits  less  than  $100  thousand  (down  0.49%),  time  deposits  $100  thousand  or  more  (down  0.26%),  preferred  money 
market savings (down 0.16%) and regular savings (down 0.08%).

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  amount  of  interest 
expense  paid  on  average  interest-bearing  liabilities  and  the  resulting  rates  paid.  Average  loan  balances  include  nonperforming 
loans. Interest income includes proceeds from loans on nonaccrual status only to the extent cash payments have been received and
applied as interest income. Yields on tax-exempt securities and loans have been adjusted upward to reflect the effect of income
exempt from federal income taxation at the current statutory tax rate.

Provision for Loan Losses

The  Company  manages  credit  costs  by  consistently  enforcing  conservative  underwriting  and  administration  procedures  and 
aggressively pursuing collection efforts with debtors experiencing financial difficulties.  

The  Company  recorded  purchased  County  and  Sonoma  loans  at  estimated  fair  value  upon  the  acquisition  dates  of  February  6, 
2009  and  August  20,  2010,  respectively.  Such  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  date  of 
purchase. Any deterioration in such conditions or reassessment by Management could require additional loss recognition through 
a provision for loan losses. The purchased County loans are “covered” by loss-sharing agreements the Company entered with the 
FDIC which mitigates any additional losses during the term of the agreements. 

In Management’s judgment, the overall borrower and economic conditions have been relatively stable for the purchased County 
loans.  However,  a  provision  for  loan  losses  of  $987  thousand,  net  of FDIC  indemnification,  was  recorded for  County  loans  in 
2011. Management believes the overall borrower and economic conditions have been relatively stable for the purchased Sonoma 
loans; no provision for loan losses was recorded for Sonoma loans in 2011. Management regularly evaluates the acquisition date 
fair value discounts and, in its judgment, believes the fair value discounts remaining at December 31, 2011 represent appropriate 
loss estimates inherent in the purchased loans. However, no assurance can be given that future provisions for loan losses related to 
purchased loans will not be necessary. 

In 2011, the provision for loan losses was $11.2 million, compared to $11.2 million for 2010 and $10.5 million for 2009. The 
provision  reflects  Management's  assessment  of  credit  risk  in  the  loan  portfolio  for  each  of  the  periods  presented.  For  further

In  2011,  noninterest  income  decreased  $1.4  million  or  2.2%  compared  with  2010.  Service  charges  on  deposits  decreased  $4.0 
million due to declines in fees charged on overdrawn accounts and insufficient funds (down $3.3 million) and deficit fees charged 
on  analyzed  accounts  (down  $580  thousand).  Financial  services  commissions  decreased  $324  thousand  due  to  lower  sales  of 
mutual  funds  and  annuities.  Merchant  processing  services  income  increased  $379  thousand  mainly  due  to  higher  transaction 
volumes. Trust fees increased $182 thousand due to increased accounts.  

In 2010 noninterest income decreased $50.6 million compared with 2009 primarily due to the $48.8 million gain on acquisition of
County in 2009. Service charges on deposits decreased $2.9 million or 7.9% due to declines in fees charged on overdrawn and 
insufficient accounts (down $2.4 million) and deficit fees charged on analyzed accounts (down $839 thousand), partially offset by
service fees charged on checking accounts (up $373 thousand). New regulations over overdraft fees were adopted July 1, 2010 
and limited the Bank’s ability to assess overdraft fees. Other categories of fees partially offset the decline in noninterest income. 
Other service fees increased $568 thousand or 25.8% mainly due to increases in check cashing fees, internet banking fees and 
foreign  currency  commissions.  Trust  fees  increased  $276  thousand  or  19.3%  mostly  due  to  new  trust  assets.  Financial  service 
commissions increased $164 thousand or 28.1%. ATM fees and interchange income was higher by $155 thousand or 4.2% due to 
increased transaction volumes.

Noninterest expense increased $531 thousand or 0.4% in 2011 compared with 2010. The 2011 results included $2.1 million in 
litigation settlement accruals and $679 thousand related to pre-integration costs for the acquired Sonoma, primarily outsourced 
data processing and personnel costs. Sonoma operations were fully integrated in February 2011. Expenses related to other real 
estate owned were $1.6 million higher in 2011 due to recognition of declines in value and payment of delinquent property taxes 
on real estate repossessed during the period. Professional fees increased $1.4 million due to higher legal fees. Occupancy expense 
increased $576 thousand primarily due to increased rental of bank premises. Loan expense increased $465 thousand primarily due 
to  increases  in  foreclosure  expense,  appraisal  fees  and  waived  fees  on  foreclosed  loans.  Operational  losses  increased  $223 
thousand due to increased fraudulent deposit account and debit card activity and branch robberies. Salaries and related benefits
decreased  $3.2  million  primarily  due  to  a  reduction  in  regular  salaries,  decreases  in  incentives,  bonuses  and  other  benefits, 
partially  offset  by  higher  group  health  insurance  costs.  Deposit  insurance  assessments  declined  $1.7  million  due  to  new 
assessment  rules  effective  April  1,  2011.  Equipment  expense  declined  $488  thousand  primarily  due  to  lower  depreciation  and 
repairs and maintenance expenses. Amortization of identifiable intangible assets declined $358 thousand as intangible assets are
amortized on a declining balance method. Advertising and public relations expense decreased $176 thousand. 

In 2010 noninterest expense decreased $13.6 million or 9.7% compared with 2009 primarily due to lower personnel, occupancy 
and equipment expenses resulting from the systems integrations and branch consolidations following the County acquisition and 
lower FDIC insurance assessments. Salaries and related benefits decreased $3.6 million or 5.6% primarily due to a reduction in 
salaries, incentives and workers compensation expense, partially offset by higher payroll taxes and group health insurance costs, 
annual  merit  increases  and  higher  stock  based  compensation.  Occupancy  and  equipment  expenses  decreased  $3.1  million  or 
16.6% and $1.5 million or 26.2%, respectively, mainly due to branch and administrative office consolidations. FDIC insurance 
assessments  decreased  $1.1  million  or  17.4%  mostly  due  to  a  non-routine  assessment  charged  in  2009.  Amortization  of 
intangibles  declined  $364  thousand  or  5.4%  as  intangible  assets  are  amortized  on  a  declining  balance  method.  Loan  expense 
decreased  $392  thousand  or  19.3%  generally  because  2009  included  servicing  fees  on  factoring  receivables  acquired  from 
County; such factoring receivables were fully liquidated in April 2009. Offsetting the decline were higher credit report expenses.
Telephone expense declined $387 thousand or 19.6% mainly due to branch and administrative office consolidations. Professional 
fees declined $207 thousand or 5.8% mainly because 2009 included County related accounting and consulting fees. Postage also 
decreased $570 thousand or 27.0% primarily because 2009 included County related expense. Other categories which decreased 
from 2009 were courier service expense (down $313 thousand or 8.2%), stationery and supplies expense (down $270 thousand or 
17.4%),  operational  losses  (down  $125  thousand  or  13.1%)  and  advertising/public  relations  expense  (down  $115  thousand  or 
11.6%). Offsetting the decreases in noninterest expense was OREO expense which increased $279 thousand or 45.3% mostly due 
to additional writedowns of foreclosed assets and higher levels of expenses due to higher volumes of foreclosed loan collateral.

Provision for Income Tax

In 2011, the Company recorded income tax provision (FTE) of $52.2 million compared with $55.2 million for 2010. The 2011 
provision represents an effective tax rate (FTE) of 37.3%, compared with 36.9% for 2010.  

The  income  tax  provision  (FTE) was $55.2  million  in  2010  compared with  $77.5  million  in  2009. The  2010  effective  tax  rate 
(FTE) was 36.9% compared to 38.2% in 2009. The lower effective tax rate (FTE) in 2010 is primarily attributable to tax-exempt 
interest income representing a higher proportion of pre-tax income and increased limited partnership tax credits. 

Investment Portfolio

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

Investment  securities  assigned  to  the  available  for  sale  portfolio  are  generally  used  to  supplement  the  Company's  liquidity, 
provide a prudent yield, and provide collateral for public deposits and other borrowing facilities. Unrealized net gains and losses 
on available for sale securities are recorded as an adjustment to equity, net of taxes, but are not reflected in the current earnings of 
the  Company. If  Management  determines  depreciation  in any  available for sale  security  is  “other  than  temporary,” a  securities 
loss will be recognized as a charge to earnings. If a security is sold, any gain or loss is reflected in current earnings and the equity 
adjustment is reversed. At December 31, 2011, the Company held $638.8 million in securities classified as investments available
for sale with a duration of 4.6 years. At December 31, 2011, an unrealized gain, net of taxes, of $11.6 million related to these
securities was included in shareholders' equity. 

Securities  assigned  to  the  held  to  maturity  portfolio  earn a  prudent  yield, provide  liquidity  from  maturities  and  paydowns,  and
provide collateral to pledge for federal, state and local government deposits and other borrowing facilities. At December 31, 2011, 
the held to maturity investment portfolio had a duration of 3.5 years and included $892.5 million in fixed-rate and $30.3 million
in adjustable-rate securities. If Management determines depreciation in any held to maturity security is “other than temporary,” a 
securities loss will be recognized as a charge to earnings. The Company had no trading securities at December 31, 2011. For more
information on investment securities, see the notes accompanying the consolidated financial statements. 

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

The following table sets forth the relative maturities and contractual yields of the Company’s available for sale securities (stated 
at fair value) at December 31, 2011. Yields on state and political subdivision securities have been calculated on a fully taxable 
equivalent  basis  using  the  current  federal  statutory  rate.  Mortgage-backed  securities  are  shown  separately  because  they  are 
typically paid in monthly installments over a number of years.

Commitments and Letters of Credit

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

Loan Portfolio Credit Risk 

The risk that loan customers do not repay loans extended by the Bank is the most significant risk to the Company. 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. 

(cid:1)

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.  

(cid:1)

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. Interest previously accrued on 
loans placed on nonaccrual status is charged against interest income, net of estimated FDIC reimbursements under loss-sharing 
agreements. The Company does not accrue interest income on nonaccrual loans. 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 or covered by 
FDIC  loss-sharing  agreements.  “Nonperforming  assets”  include  nonaccrual  loans,  loans  90  or  more  days  past  due  and  still 
accruing, and repossessed loan collateral. 

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. 

On February 6, 2009, the Bank purchased loans and repossessed loan collateral of the former County Bank from the FDIC. This 
purchase  transaction  included  loss-sharing  agreements  with  the  FDIC  wherein  the  FDIC  and  the  Bank  share  losses  on  the 
purchased assets. The loss-sharing agreements significantly reduce the credit risk of these purchased assets. In evaluating credit 
risk,  Management  separates  the  Bank’s  total  loan  portfolio  between  those  loans  qualifying  under  the  FDIC  loss-sharing

agreements (referred to as “purchased covered loans”) and loans not qualifying under the FDIC loss-sharing agreements (referred
to  as  “purchased  non-covered  loans”  and  “originated  loans”).  At  December  31,  2011,  purchased  covered  loans  totaled  $535 
million, or 21 percent of total loans, originated loans totaled $1.9 billion, or 74 percent and purchased non-covered loans totaled 
$126 million, or 5 percent of total loans. 

Purchased covered loans and repossessed loan collateral qualify under loss-sharing agreements with the FDIC. Under the terms of
the loss-sharing agreements, the FDIC absorbs 80 percent of losses and shares in 80 percent of loss recoveries on the first $269
million  in  losses  on  purchased  covered  assets  (“First  Tier”),  and  absorbs  95  percent  of  losses  and  shares  in  95  percent  of  loss
recoveries  if  losses  on  purchased  covered  assets  exceed  $269  million  (“Second  Tier”).  The  loss-sharing  agreement  on  covered 
residential  real  estate  assets  expires  February  6, 2019  and the loss-sharing  agreement  on  covered non-residential  assets  expires
February 6, 2014 as to losses and February 6, 2017 as to loss recoveries. 

The purchased covered assets are primarily located in the California Central Valley, including Merced County. This geographic 
area  currently  has  some  of  the  weakest  economic  conditions  within  California  and  has  experienced  significant  declines  in  real 
estate values. Management expects higher loss rates on purchased covered assets than on originated assets. 

The  Bank  recorded  purchased  covered  assets  at  estimated  fair  value  on  the  February  6,  2009  acquisition  date.  The  credit  risk 
discount  ascribed  to  the  $1.2  billion  acquired  loan  and  repossessed  loan  collateral  portfolio  was  $161  million  representing 
estimated losses inherent in the assets at the acquisition date. The Bank also recorded a related receivable from the FDIC in the
amount of $129 million representing estimated FDIC reimbursements under the loss-sharing agreements. 

The maximum risk to future earnings if First Tier losses exceed Management’s estimated $161 million in recognized losses under 
the FDIC loss-sharing agreements is estimated to be $12 million as follows (Dollars in thousands): 

First Tier Loss Coverage 
Less: Recognized credit risk discount 
Exposure to under-estimated risk within First Tier 
Bank loss-sharing percentage 
First Tier risk to Bank, pre-tax 
First Tier risk to Bank, after-tax 

$269,000 
   161,203
   107,797 
20 percent
   $21,559
   $12,494

Management  has  judged  the  likelihood  of  experiencing  losses  of  a  magnitude  to  trigger  Second  Tier  FDIC  reimbursement  as 
remote. The Bank’s maximum after-tax exposure to Second Tier losses is $13 million as of December 31, 2011, which would be 
realized only if all purchased covered assets at December 31, 2011 generated no future cash flows. 

Purchased covered assets have declined since the acquisition date, and losses have been offset against the estimated credit risk
discount.  Purchased  covered  assets  totaled  $554  million  at  December  31,  2011,  net  of  a  credit  risk  discount  of  $46  million, 
compared  to  $715  million  at  December  31,  2010,  net  of  a  credit  risk  discount  of  $62  million.  Purchased  covered  assets  are 
evaluated for risk classification without regard to FDIC indemnification such that Management can identify purchased covered 
assets with potential payment problems and devote appropriate credit administration practices to maximize collections. Classified
purchased covered assets without regard to FDIC indemnification totaled $168 million and $195 million at December 31, 2011 
and December 31, 2010, respectively. FDIC indemnification limits the Company’s loss exposure to covered classified assets. 

Allowance for Credit Losses

The Company’s allowance for credit losses represents Management’s estimate of credit losses inherent in the loan portfolio. In 
evaluating credit risk for loans, Management measures loss potential of the carrying value of loans. As described above, payments
received on nonaccrual loans may be applied against the principal balance of the loans until such time as full collection of the
remaining recorded balance is expected. Further, the carrying value of purchased loans includes fair value discounts assigned at 
the time of purchase under the provisions of FASB ASC 805, Business Combinations, and FASB ASC 310-30, Loans or Debt 
Securities with Deteriorated Credit Quality. The allowance for credit losses represents Management’s estimate of credit losses in 
excess of these principal reductions.

The  Company's  allowance  for  credit  losses  is  maintained  at  a  level  considered  appropriate  to  provide  for  losses  that  can  be 
estimated based upon specific and general conditions. These include conditions unique to individual borrowers, as well as overall 
credit  loss  experience,  the  amount  of  past  due,  nonperforming  loans  and  classified  loans,  FDIC  loss-sharing  indemnification, 
recommendations  of  regulatory  authorities,  prevailing  economic  conditions  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. A second allocation is based in part on quantitative analyses of historical credit loss experience, 
in  which  criticized  and  classified  credit  balances  identified  through  an  independent  internal  credit  review  process  are  analyzed 
using a linear regression model to determine standard loss rates. The results of this analysis are applied to current criticized and 
classified loan balances to allocate the allowance to the respective segments of the loan portfolio. In addition, loans with similar 
characteristics not usually criticized using regulatory guidelines are analyzed based on the historical loss rates and delinquency 
trends, grouped by the number of days the payments on these loans are delinquent. Given currently weak economic conditions, 
Management  is  applying  further  analysis to  consumer  loans.  Current  levels  of  indirect automobile  loan  losses  are  compared  to 
initial allowance allocations and, based on Management judgment, additional allocations are applied, if needed, to estimate losses. 
For residential real estate loans, Management is comparing ultimate loss rates on foreclosed residential real estate properties and 
applying  such  loss  rates  to  nonaccrual  residential  real  estate  loans.  Based  on  this  analysis,  Management  exercises  judgment  in 
allocating additional allowance if deemed appropriate to estimate losses on residential real estate loans. Last, allocations are made 
to non-criticized and non-classified commercial and commercial real estate loans based on historical loss rates and other statistical 
data.  

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.  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 loan chargeoff 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  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  loan
category in a statistically meaningful manner and are difficult to quantify with a specific number. Management assigns a range of
estimated risk to the qualitative risk factors described above based on Management's judgment as to the level of risk, and assigns 
a  quantitative  risk  factor  from  the  range  of  loss  estimates  to  determine  the  appropriate  level  of  the  unallocated  portion  of  the
allowance. Management considers the $35.3 million allowance for credit losses to be adequate as a reserve against credit losses
inherent in the loan portfolio as of December 31, 2011. 

See Note 4 to the consolidated financial statements for additional information related to the allowance for credit losses. 

Impaired Loans

The Company considers a loan to be impaired when, based on current information and events, it is probable that it will be unable
to collect all amounts due (principal and interest) according to the contractual terms of the loan agreement. The measurement of
impairment may be based on (i) the present value of the expected cash flows of the impaired loan discounted at the loan’s original 
effective interest rate, (ii) the observable market price of the impaired loan or (iii) the fair value of the collateral of a collateral-
dependent  loan.  The  Company  does  not  apply  this  definition  to  smaller-balance  loans  that  are  collectively  evaluated  for  credit 
risk. In assessing impairment, the Company reviews all nonaccrual commercial and construction loans with outstanding principal 
balances in excess of $1 million. Nonaccrual commercial and construction loans with outstanding principal balances less than $1
million, and large groups of smaller-balance homogeneous loans such as installment, personal revolving credit and residential real 
estate loans, are evaluated collectively for impairment under the Company’s standard loan loss reserve methodology. 

Impaired purchased loans were recorded at estimated fair value on the acquisition date. 

The following summarizes the Company’s recorded investment in impaired originated loans for the dates indicated: 

At December 31, 
(In thousands) 
2011 
Total impaired loans.................................................................
  $4,525 
Specific reserves ......................................................................   $2,023 

2010 
 $12,748 
  $1,365 

At December 31, 2011 and 2010, the Company measured impairment using the fair value of loan collateral. The average balance 
of the Company’s impaired originated loans for the year ended December 31, 2011 was $4.1 million compared with $2.5 million 
in  2010.  All  impaired  loans  are  on  nonaccrual  status.  See  Note  4  to  the  consolidated  financial  statements  for  additional 
information related to the impaired loans. 

Asset/Liability and Market Risk Management 

Interest  rate  risk  is  a  significant  market  risk  affecting  the  Company.  Interest  rate  risk  results  from  many  factors.  Assets  and
liabilities may mature or reprice at different times. Assets and liabilities may reprice 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,  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. 

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 ranged from “neutral” to slightly “asset sensitive” at December 31, 2011, depending 
on  the  interest  rate  assumptions  applied  to  the  simulation  model  employed  by  Management  to  measure  interest  rate  risk.  A 
“neutral”  position  results  in  similar  amounts  of  change  in  interest  income  and  interest  expense  resulting  from  application  of 
assumed interest rate changes. An “asset sensitive” position results in a larger change in interest income than in interest expense 
resulting from application of assumed interest rate changes. Management’s simulation modeling is currently biased toward rising

37

 
 
 
 
 
 
 
 
 
 
interest rates. Management continues to monitor the interest rate environment as well as economic conditions and other factors it 
deems relevant in managing the Company's exposure to interest rate risk. 

Management assesses interest rate risk by comparing the Company's most likely earnings plan with various earnings models using 
many  interest  rate  scenarios  that  differ  in  the  direction  of  interest  rate  changes,  the  degree  of  change  over  time,  the  speed  of
change and the projected shape of the yield curve. For example, using the current composition of the Company's balance sheet 
and assuming an increase of 100 basis points (“bp”) in the federal funds rate and an increase of 60 bp in the 10 year Constant 
Maturity Treasury Bond yield during the same period, earnings are not estimated to change by a meaningful amount compared to 
the Company's most likely net income plan for the twelve months ending December 31, 2012. 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. In  the  current
operating environment, Management’s objective is to maintain a “neutral” to slightly “asset sensitive” interest rate risk position. 
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 for purposes of computing earnings
per share. 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. 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 Company's routine sources of liquidity are operating earnings, investment securities, consumer and other loans, deposits, and 
other  borrowed  funds.  In  2011,  the  Company’s  operating  activities  generated  $120  million  in  liquidity  providing  funds  to  pay 
common shareholders $42 million in dividends, fund $61 million in stock repurchases and redeem $10 million in subordinated 
debt.  During  2010,  the  Company’s  operating  activities  generated  $115  million  in  liquidity  providing  adequate  funds  to  pay 
common shareholders $42 million in dividends and fund $29 million in stock repurchases. In 2011, investment securities provided
$430  million  in  liquidity  from  sales,  paydowns  and  maturities,  and  loans  provided  $342  million  in  liquidity  from  scheduled 
payments  and  maturities,  net  of  loan  fundings.  Additionally,  deposit  growth  increased  cash  $118  million.  In  2011,  liquidity 
provided  funds  to  purchase  securities  of  $733  million  and  to  reduce  short-term  borrowings  by  $17  million  and  redeem  a  $10 
million subordinated debt. In 2010, loans provided $299 million in liquidity from scheduled payments, paydowns and maturities, 
net of loan fundings. The Company purchased $483 million in investment securities using $131 million in cash and $352 million 
from  paydowns  and  maturities  of  investment  securities.  The  Company  primarily  purchased  securities  of  U.S.  Government 
sponsored  entities,  obligations  of  states  and  political  subdivisions,  and  corporate  securities  to  offset  decreases  in  residential
mortgage  backed  securities  and  residential  collateralized  mortgage  obligations.  Other  sources  of  cash  from  investing  activities
include net cash of $58 million from an acquisition, proceeds of $41 million under FDIC loss-sharing agreements and proceeds of
$32 million from sale of foreclosed assets. Cash was applied to reduce short term borrowings by $206 million and to meet a net 
reduction in deposits totaling $177 million.

At  December  31,  2011,  the  Company’s  assets  included  $530  million  in  cash  and  amounts  due  from  other  banks  from  daily 
transaction settlements. The Bank maintains cash balances for its branches of approximately $50 million to meet the routine needs
of  its  customers.  Further,  the  Bank  must  maintain  approximately  $30  million  at  the  Federal  Reserve  Bank  (FRB)  to  meet  its 
reserve  requirement;  this  reserve  requirement  is  reduced  by  cash  held  for  branches.  Excluding  cash  for  branch  needs  and  cash 
required at the FRB, cash and amounts due from other banks from daily transaction settlements of approximately $450 million 
provided excess liquidity equivalent to eleven percent of total deposits. 

The  Company  projects  $209  million  in  additional  liquidity  from  investment  security  paydowns  and  maturities  in  the  twelve 
months  ending  December  31,  2012.  At  December  31,  2011,  indirect  automobile  loans  totaled  $412  million,  which  were 
experiencing stable monthly principal payments of approximately $16 million during the last three months of 2011. 

The Company held $1.6 billion in total investment securities at December 31, 2011. Under certain deposit, borrowing and other 
arrangements, the Company must pledge investment securities as collateral. At December 31, 2011, such collateral requirements 
totaled approximately $904 million. At December 31, 2011, $639 million of the Company's investment securities were classified 
as "available-for-sale", and as such, could provide additional liquidity if sold, subject to the Company's ability to meet continuing 
collateral  requirements.  In  addition,  at  December  31,  2011,  the  Company  had  customary  lines  for  overnight  borrowings  from 
other financial institutions in excess of $700 million, under which $-0- was outstanding. Additionally, the Company has access to 
borrowing from the Federal Reserve. The Company's short-term debt rating from Fitch Ratings is F1. The Company's long-term 
debt rating from Fitch Ratings is A with a stable outlook. Management expects the Company could access additional long-term 
debt  financing  if  desired.  In  Management's  judgment,  the  Company's  liquidity  position  is  strong  and  asset  liquidations  or 
additional long-term debt are considered unnecessary to meet the ongoing liquidity needs of the Company. 

Management  will  monitor  the  Company’s  cash  levels  throughout  2012.  Loan  demand  from  credit-worthy  borrowers  will  be 
dictated  by  economic  and  competitive  conditions  for  the  remainder  of  2012.  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 gradually 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 
concerns such as uncertainty in the general economic environment, competition and political uncertainty, loan demand and levels
of  customer  deposits  are  not  certain.  Shareholder  dividends  are  expected  to  continue  subject  to  the  Board's  discretion  and 
continuing evaluation of capital levels, earnings, asset quality and other factors. 

The  Company  performs  liquidity  stress  tests  on  a  periodic  basis  to  evaluate  the  sustainability  of  its  liquidity.  Under  the  stress 
testing,  the  Company  assumes  outflows  of  funds  increase  beyond  expected  levels.  Measurement  of  such  heightened  outflows 
considers the composition of the Company’s deposit base, including any concentration of deposits, non-deposit funding such as 
short-term borrowings and Federal Home Loan Bank advances, and unfunded lending commitments. The Company evaluates its 
stock of highly liquid assets to meet the assumed higher levels of outflows. Highly liquid assets include cash and amounts due 
from other banks from daily transaction settlements, reduced by branch cash needs and FRB reserve requirement, 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. 

Westamerica  Bancorporation  ("Parent  Company")  is  a  separate  entity  and  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 outstanding debt. Substantially all of the Parent Company's 
revenues are obtained from subsidiary dividends and service fees. Payment of dividends to the Parent Company by the Bank is 
limited under California and Federal laws. The Company believes that regulatory dividend restrictions will not have an impact on
the Parent Company's ability to meet its ongoing cash obligations. During 2011, 2010 and 2009, the Bank declared dividends to 
the Company of $107 million, $69 million and $93 million, respectively.

Long-term  debt  obligations  and operating  lease  obligations  may  be retired  prior  to  the  contractual  maturity  as  discussed  in  the
notes  to  the  consolidated  financial  statements.  The  purchase  obligation  consists  of  the  Company’s  minimum  liability  under  a 
contract with a third-party automation services provider. 

Capital Resources

The Company has historically generated high levels of earnings, which provides a means of raising capital. The Company's net 
income as a percentage of average shareholders' equity (“return on equity” or “ROE”) has been 25.8% in 2009, 18.1% in 2010 
and  16.1%  in  2011.  The  Company  also  raises  capital  as  employees  exercise  stock  options,  which  are  awarded  as  a  part  of  the 
Company's  executive  compensation  programs  to  reinforce  shareholders'  interests  in  the  Management  of  the  Company.  Capital 
raised through the exercise of stock options totaled $9.6 million in 2009, $16.7 million in 2010 and $14.4 million in 2011. 

The Company paid common dividends totaling $41.1 million in 2009, $42.1 million in 2010 and $41.7 million in 2011, which 
represent dividends per common share of $1.41, $1.44 and $1.45, respectively. In 2009, the Company was unable to, without the 
consent of the Treasury, to increase the cash dividend on the Company’s common stock above $0.35 per share, while the Treasury 
Preferred  Stock  was  outstanding.  This  restriction  was  removed  upon  full  redemption  of  the  Treasury  Preferred  Stock  on 
November 18, 2009. The Company's earnings have historically exceeded dividends paid to shareholders. The amount of earnings 
in excess of dividends gives 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  42  thousand  shares valued  at $2.0  million  in  2009, 533 
thousand  shares  valued  at  $28.7  million  in  2010,  and  1.3 million  shares  valued  at  $60.5  million  in  2011.  Share  repurchases  in 
most  of  2009  were  restricted  to  amounts  conducted  in  coordination  with  employee  benefit  programs  under  the  terms  of  the 
February 13, 2009 issuance of Treasury Preferred Stock until complete redemption of the same preferred stock on November 18, 
2009. 

The Company's primary capital resource is shareholders' equity, which increased $13.4 million or 2.4% in 2011 from the previous
year. For 2011, the Company earned $87.9 million in net income, raised $14.4 million from the issuance of stock in connection 
with exercises of employee stock options, paid $41.7 million  in common dividends, and repurchased $60.5 million in common 
stock.

The Company's ratio of equity to total assets was 11.08% at December 31, 2011 and 11.06% at December 31, 2010. 

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 

The following summarizes the ratios of regulatory capital to risk-adjusted assets for the Company on the dates indicated: 

At December 31, 
Tier I Capital ...........................................................................   14.54%   14.21%

The Company's risk-based capital ratios increased at December 31, 2011, compared with December 31, 2010, primarily due to a 
decline in risk-weighted assets.  

The following summarizes the ratios of capital to risk-adjusted assets for the Bank on the dates indicated: 

At December 31, 
Tier I Capital ...........................................................................   13.84%   13.87%

FDIC-covered assets are generally included in the 20% risk-weighted category due to loss sharing agreements, which expire on 
February 5, 2019 as to the residential real estate covered assets and on February 5, 2014 as to non-residential real estate covered 
assets.  Subsequent  to  such  dates,  previously  FDIC-indemnified  assets  will  generally  be  included  in  the  100%  risk-weight 
category.

The Company and the Bank intend to maintain regulatory capital in excess of the highest regulatory standard, referred to as “well
capitalized”.  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  “well  capitalized”  standard  and pay  quarterly  dividends  to  shareholders. No  assurance  can  be  given  that  changes  in  capital 
management plans will not occur. 

Deposit categories

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

The following table summarizes the Company’s average daily amount of deposits and the rates paid for the periods indicated:

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 2010 to 2011 the deposit composition shifted from higher costing time 
deposits  to  lower  costing  checking  and  savings  accounts.  The  Company’s  average  checking  and  savings  accounts  represented 
80% of total deposits in 2011 compared with 77% in 2010 and 74% in 2009.  

Total time deposits were $804.5 million and $895.6 million at December 31, 2011 and 2010, 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 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, 2011. 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,  2011  based  upon  criteria  in  Internal  Control  —  Integrated  Framework  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,  2011  based  on  the  criteria  in  Internal  Control  - 
Integrated Framework issued by COSO. 

The Company’s independent registered public accounting firm has issued an attestation report on Management’s assessment of 
the Company’s internal control over financial reporting. This report is included below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders 
Westamerica Bancorporation:  

We  have  audited  Westamerica  Bancorporation  and  subsidiaries  (the  Company)  internal  control  over  financial  reporting  as  of 
December  31,  2011,  based  on  criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of 
Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  The  Company’s  management  is  responsible  for  maintaining 
effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the  effectiveness  of  internal  control  over  financial
reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility 
is to express an opinion on the Company’s internal control over financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control 
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control 
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating 
effectiveness  of  internal  control  based  on  the  assessed  risk.  Our  audit  also  included  performing  such  other  procedures  as  we 
considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

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

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

In  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal  control  over  financial  reporting  as  of 
December  31,  2011,  based  on  criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated  balance  sheets  of  the  Company  as  of  December  31,  2011  and  2010,  and  the  related  consolidated  statements  of 
income, changes in shareholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period
ended  December  31,  2011,  and  our  report  dated  February  27,  2012  expressed  an  unqualified  opinion  on  those  consolidated 
financial statements.

WESTAMERICA BANCORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Business and Accounting Policies

Westamerica Bancorporation, a registered bank holding company (the “Company”), provides a full range of banking services to 
corporate  and  individual  customers  in  Northern  and  Central  California  through  its  subsidiary  bank,  Westamerica  Bank  (the 
“Bank”).  The Bank  is subject  to  competition  from  both  financial  and  nonfinancial  institutions  and  to the  regulations  of  certain
agencies and undergoes periodic examinations by those regulatory authorities. 

The Company has evaluated events and transactions subsequent to the balance sheet date. Based on this evaluation, the Company 
is not aware of any events or transactions that occurred subsequent to the balance sheet date but prior to filing that would require 
recognition or disclosure in its consolidated financial statements. 

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  2012  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,” estimated fair values of purchased loans, as discussed below under “Purchased Loans,” and 
the evaluation of other than temporary impairment, as discussed below under “Securities.” 

As described in Note 2 below, the Bank acquired assets and assumed liabilities of the former Sonoma Valley Bank (“Sonoma”) 
on August 20, 2010. The acquired assets and assumed liabilities were measured at estimated fair values, as required by Financial
Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 805, Business Combinations. Management made 
significant estimates and exercised significant judgment in accounting for the acquisition. Management judgmentally  measured 
loan fair values based on loan file reviews (including borrower financial statements and tax returns), appraised collateral values, 
expected cash flows, and historical loss factors. Repossessed loan collateral was primarily valued based upon appraised collateral
values.  The  Bank  also  recorded  an  identifiable  intangible  asset  representing  the  value  of  the  core  deposit  customer  base  of 
Sonoma based on Management’s evaluation of the cost of such deposits relative to alternative funding sources. In determining the
value of the identifiable intangible asset, Management used significant estimates including average lives of depository accounts,
future interest rate levels, the cost of servicing various depository products, FDIC assessment rates and other significant estimates. 
Management used quoted market prices to determine the fair value of investment securities and FHLB advances. 

The Bank acquired assets and assumed liabilities of the former County Bank (“County”) on February 6, 2009 from the Federal 
Deposit Insurance Corporation (“FDIC”). The acquired assets and assumed liabilities of County were measured at estimated fair 
values, as required by the acquisition method of accounting for business combinations (FASB ASC 805, Business Combinations, 
formerly FASB Statement No. 141 (revised 2007)). Management made significant estimates and exercised significant judgment in 
accounting  for  the  acquisition  of  County.  Management  judgmentally  assigned  risk  ratings  to  loans.  The  assigned  risk  ratings, 
appraised collateral values, expected cash flows, current interest rates, and statistically derived loss factors were used to measure
fair values for loans. Repossessed loan collateral was primarily valued based upon appraised collateral values. Due to the loss-
sharing  agreements  with  the  FDIC,  the  Bank  recorded  a  receivable  from  the  FDIC  equal  to  80  percent  of  the  loss  estimates 
embedded  in  the  fair  values  of  loans  and  repossessed  loan  collateral.  The  Bank  also  recorded  an  identifiable  intangible  asset 
representing  the  value  of  the  core  deposit  customer  base  of  County  based  on  an  appraisal  performed  by  an  independent  third 
party. In determining the value of the identifiable intangible asset, the third-party appraiser used significant estimates including 
average  lives  of  depository  accounts,  future  interest  rate  levels,  the  cost  of  servicing  various  depository  products,  and  other
significant estimates. Management used quoted market prices to determine the fair value of investment securities, FHLB advances
and other borrowings.

The  acquired  assets  of  Sonoma  include  loans  which  are  not  indemnified  by  the  FDIC.    The  acquired  loans  of  County  are 
indemnified  under  loss-sharing  agreements  with  the  FDIC.  Pursuant  to  acquisition  accounting,  the  loans  in  each  business 
combination were measured at their estimated fair value at the respective acquisition date. This method of measuring the carrying 
value of purchased loans differs from loans originated by the Company, and as such, the Company identifies purchased loans not 
indemnified  by  the  FDIC  as  “Purchased  Non-covered  Loans”  and  purchased  loans  indemnified  by  the  FDIC  as  “Purchased 
Covered Loans.” Loans originated by the Company are measured at the principal amount outstanding, net of unearned discount 
and unamortized deferred fees and costs. These loans are identified as “Originated Loans.”   

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

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

Securities. Investment securities consist of debt securities of the U.S. Treasury, government sponsored entities, states, counties,  
municipalities, corporations, mortgage-backed securities, 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.  Held  to 
maturity securities are those debt securities which the Company has the ability and intent to hold until  maturity. Securities not 
included in trading or held to maturity are classified as available for sale. Trading and available for sale securities are recorded at 
fair value. Held to maturity securities are recorded at cost, adjusted for the amortization of premiums or accretion of discounts.
Unrealized  gains  and  losses  on  trading  securities  are  included  in  earnings.  Unrealized  gains  and  losses,  net  of  the  related  tax
effect, on available for sale securities are reported as a separate component of shareholders’ equity. 

A decline in the market value of any available for sale or held to maturity security below 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.

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 in interest income 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  for  various  purposes,  such  as  to  meet  regulatory  requirements  (for  example, 
Federal  Home  Loan  Bank  and  Federal  Reserve  Bank  stock).  These  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 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 as a loss from equity investments 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 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  to  the  allowance  for  credit  losses  when  they  become  120  days  past  due.  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  with  Deteriorated  Credit  Quality,  when  the  loans  have 
evidence of credit deterioration since origination and it is probable at the date of acquisition that the Company will not collect all 
contractually  required  principal  and  interest  payments.  Evidence  of  credit  quality  deterioration  as  of  the  purchase  date  may 
include  attributes  such  as  past  due  and  nonaccural  status.  Generally,  purchased  loans  that  meet  the  Company’s  definition  for 
nonaccrual  status  fall  within  the  scope  of  FASB  ASC  310-30.  The  difference  between  contractually  required  payments  at 
acquisition and the cash flows expected to be collected at acquisition is referred to as the nonaccretable difference. Subsequent 
decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows result 
in  a  reversal  of  the  provision  for  loan  losses  to  the  extent  of  prior  charges,  or  a  reclassification  of  the  difference  from 
nonaccretable to accretable with a positive impact on interest income. Any excess of expected cash flows over the estimated fair
value is referred to as the accretable yield and is recognized into interest income over the remaining life of the loan when there is 
a reasonable expectation about the amount and timing of such cash flows. 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 is accrued
daily  on  the  outstanding  principal  balances.  Covered  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  covered  loans  on  which  full  recovery  of 
principal  or  interest  is  in  doubt,  are  placed  on  nonaccrual  status.  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. In addition, some covered loans secured by real estate 
with  temporarily  impaired  values  and  covered  commercial  loans  to  borrowers  experiencing  financial  difficulties  are  placed  on 
nonaccrual status even though the borrowers continue to repay the loans as scheduled (“covered performing nonaccrual loans”). 
Interest payments received on nonaccrual loans are applied to interest income on a cash basis.  Covered 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.

Allowance  for  Credit  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  credit  losses  when  all  or  a  portion  of  the 
recorded amount of a loan is deemed to be uncollectible. Recoveries of loans previously charged off are credited to the allowance
when realized. The Company’s allowance for credit losses is maintained at a level considered adequate to provide for 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.  A  second  allocation  is  based  in  part  on  quantitative  analyses  of 
historical credit loss experience, in which criticized and classified loan balances identified through an internal loan review process 
are analyzed using a linear regression model to determine standard loss rates. The results of this analysis are applied to current
criticized  and  classified  loan  balances  to  allocate  the  reserve  to  the  respective  commercial,  commercial  real  estate,  and 
construction  segments  of  the  loan  portfolio.  In  addition,  residential  real  estate  and  consumer  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.  Last, 
allocations  are  made  to  non-criticized  and  non-classified  commercial,  commercial  real  estate  and  construction  loans  based  on 
historical  loss  rates.  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 category in a statistically meaningful manner and are difficult to quantify with a specific number. 

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  and 
construction  loans.  Historical  credit  loss  factors  for  commercial  and  construction  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  lower  of  the  related  loan  carrying  value  or  fair  value  of  the  collateral,  generally  based  upon  an  independent 
property appraisal, less estimated disposition costs. Subsequently, other real estate owned is valued at the lower of the amount
recorded at the date acquired or the then current fair value less estimated disposition costs. Subsequent losses incurred 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,  acquisition  date  fair  value  discounts  on  the  related  loans  are  also  transferred  to  covered  other  real  estate
owned. Fair value adjustments on covered other real estate owned result in a reduction of the covered other real estate carrying
amount and a corresponding increase in the estimated FDIC reimbursement, with the estimated net loss charged against earnings. 

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

Intangible Assets. Intangible assets are comprised of goodwill, core deposit intangibles and other identifiable intangibles acquired 
in business combinations. Intangible assets with definite useful lives are amortized on an accelerated basis over their respective
estimated useful lives not exceeding 15 years. If an event occurs that indicates the carrying amount of an intangible asset may not

be  recoverable,  Management  reviews  the  asset  for  impairment.  Any  goodwill  and  any  intangible  asset  acquired  in  a  purchase 
business combination determined to have an indefinite useful life is not amortized, but is evaluated for impairment annually. 

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. 

Derivative  Instruments  and  Hedging  Activities.  The  Company’s  accounting  policy  for  derivative  instruments  requires  the 
Company to recognize those items as assets or liabilities in the statement of financial position and measure them at fair value.
Hybrid  financial  instruments  are  single  financial  instruments  that  contain  an  embedded  derivative.  The  Company’s  accounting 
policy is to record certain hybrid financial instruments at fair value without separating the embedded derivative. 

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

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

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

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

Recently Adopted Accounting Pronouncements 

In 2011, the Company adopted the following new accounting guidance: 

 FASB Accounting Standards Update (ASU) 2011-02, A Creditor’s Determination of Whether a Restructuring is a Troubled Debt 
Restructuring, was issued April 2011 providing additional guidance for creditors in determining whether a creditor has granted a 
concession  and  whether  a  debtor  is  experiencing  financial  difficulties  for  purposes  of  determining  whether  a  restructuring 
constitutes  a  troubled  debt  restructuring.    The  provisions  of  this  standard  are  effective  for  the  first  interim  or  annual  period
beginning on or after June 15, 2011 with early adoption permissible, and should be applied retrospectively to the beginning of the 
annual period of adoption. The Company early adopted the provisions of this standard effective April 1, 2011 with retrospective
application to January 1, 2011. The results of the adoption of this Update are disclosed in Note 4. 

FASB ASU 2011-01, Deferral of the Effective Date of Disclosures about Troubled Debt Restructurings in Update No. 2010-20 
(Topic 310), was issued January 2011 deferring the new disclosure requirements (paragraphs 310-10-50-31 through 50-34 of the 
FASB  Accounting  Standards  Codification)  about  troubled  debt  restructurings  to  be  concurrent  with  the  effective  date  of  the 
guidance for determining what constitutes a troubled debt restructuring, as presented in proposed Accounting Standards Update,

Receivables (Topic 310): Clarifications to Accounting for Troubled Debt Restructurings by Creditors. As a result of the issuance 
of Update 2011-02, the provisions of Update 2011-01 are effective for the first interim or annual period beginning on or after June 
15,  2011  or  July  1,  2011  for  the  Company,  and  should  be  applied  retrospectively  to  the  beginning  of  the  annual  period  of 
adoption. The Company adopted the Update concurrent with ASU 2011-02. 

Recently Issued Accounting Standards 

FASB  ASU  2011-03, Reconsideration  of  Effective  Control  for  Repurchase  Agreements,  was  issued  April  2011  addressing  the 
accounting  for  repurchase  agreements  and  other  agreements  that  both  entitle  and  obligate a  transferor  to  repurchase  or  redeem 
financial assets before their maturity.  The amendments remove from the assessment of effective control (1) the criterion requiring 
the transferor to have the ability to repurchase or redeem the financial assets on substantially the agreed terms, even in the event 
of default by the transferee, and (2) the collateral maintenance implementation guidance related to that criterion.  The provisions 
of this Update are effective for the first interim or annual period beginning on or after December 15, 2011, and should be applied
prospectively to transactions or modifications of existing transactions that occur on or after the effective date.  The adoption of the 
Update will not have a material effect on the Company’s financial statements at the date of adoption. 

 FASB ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP 
and IFRSs, was issued May 2011 as a result of the FASB and International Accounting Standards Board’s (IASB) goal to develop 
common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with 
U.S. generally accepted accounting principles and International Financial Reporting Standards. The provisions of this Update are
effective  during  the  interim  or  annual  periods  beginning  after  December  15,  2011,  and  are  to  be  applied  prospectively.    The 
adoption of the Update will not have a material effect on the Company’s financial statements at the date of adoption. 

FASB ASU 2011-05, Presentation of Comprehensive Income, was issued June 2011 requiring that all changes in stockholders’ 
equity  be  presented  either  in  a  single  continuous  statement  of  comprehensive  income  or  in  two  separate  but  consecutive 
statements.  This Update also requires that reclassification adjustments for items that are reclassified from other comprehensive 
income to net income be presented on the face of the financial statements.  The provisions of this Update are effective for fiscal 
years, and interim periods within those years, beginning after December 15, 2011, and are to be applied retrospectively.  Early
adoption is permitted.  The adoption of the Update will not have a material effect on the Company’s financial statements at the
date of adoption. 

FASB  ASU  2011-12, Deferral  of  the  Effective  Date  for  Amendments  to  the  Presentation  of  Reclassifications  of  Items  Out  of 
Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05, was issued December 2011 updating 
and  superseding  certain  pending  paragraphs  relating  to  the  presentation  on  the  face  of  the  financial  statements  the  effects  of 
reclassifications  out  of  accumulated  other  comprehensive  income  on  the  components  of  net  income  and  other  comprehensive 
income.    This  Update  is  effective  concurrent  with  ASU  2011-05,  Presentation  of  Comprehensive  Income,  and  will  not  have  a 
material effect on the Company’s financial statements at the date of adoption. 

FASB  ASU  2011-08, Testing  for  Goodwill  Impairment,  was  issued  September  2011  giving  an  entity  the  option  to  first  assess 
qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely
than  not  that  the  fair  value  of  a  reporting  unit  is  less  than  its  carrying  amount.  If,  after  assessing  the  totality  of  events  or
circumstances,  an  entity  determines  it  is  more  likely  than  not  that  the  fair  value  of  a  reporting  unit  is  more  than  its  carrying
amount,  then  performing  the  two-step  impairment  test  is  unnecessary.  However,  if  an  entity  concludes  otherwise,  then  it  is 
required to perform the first step of the two-step impairment test by calculating the fair value of the reporting unit and comparing
the fair value with the carrying amount of the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, then 
the entity is required to perform the second step of the goodwill impairment test to measure the amount of the impairment loss, if 
any. Under the amendments in this Update, an entity has the option to bypass the qualitative assessment for any reporting unit in 
any  period  and  proceed  directly  to  performing  the  first  step  of  the  two-step  goodwill  impairment  test.  An  entity  may  resume 
performing  the  qualitative  assessment  in  any  subsequent  period.  The  provisions  of  this  standard  are  effective  for  annual  and 
interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. 
The adoption of the Update will not have a material effect on the Company’s financial statements at the date of adoption. 

FASB  ASU  2011-11, Disclosures  about  Offsetting  Assets  and  Liabilities,  was  issued  December  2011  to  require  an  entity  to 
disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect 
of  those  arrangements  on  its  financial  position.  An  entity  is  required  to  apply  the  amendments  for  annual  reporting  periods 
beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures

required by those amendments retrospectively for all comparative periods presented.  The Update will not have a material effect
on the Company’s financial statements at the date of adoption. 

Note 2:  Acquisition

On August 20, 2010, the Bank purchased substantially all the assets and assumed substantially all the liabilities of Sonoma from
the  FDIC,  as  Receiver  of  Sonoma.  Sonoma  operated  3  commercial  banking  branches  within  Sonoma  County,  California.  The 
FDIC took Sonoma  under receivership upon Sonoma’s closure by the California Department of Financial Institutions at the close 
of  business  August  20,  2010.  Westamerica  Bank  purchased  substantially  all  of  Sonoma’s  net  assets  at  a  discount  of  $43,000 
thousand and paid a $5,008 thousand deposit premium. 

The  Sonoma  acquisition  was  accounted  for  under  the  purchase  method  of  accounting  in  accordance  with  FASB  ASC  805, 
Business Combinations. The statement of net assets acquired as of August 20, 2010 and the resulting bargain purchase gain are 
presented in the following table. The purchased assets and assumed liabilities were recorded at their respective acquisition date
fair  values,  and  identifiable  intangible  assets  were  recorded  at  fair  value.  A  “bargain  purchase”  gain  totaling  $178  thousand 
resulted from the acquisition and is included as a component of noninterest income on the statement of income. The amount of the
gain is equal to the amount by which the fair value of assets purchased exceeded the fair value of liabilities assumed. Sonoma’s
results of operations prior to the acquisition are not included in Westamerica’s statement of income.

Expected maturities of mortgage-backed securities can differ from contractual maturities because borrowers have the right to call
or prepay obligations with or without call or prepayment penalties. In addition, such factors as prepayments and interest rates may 
affect the yield on the carrying value of mortgage-backed securities. At December 31, 2011 and 2010, 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.  
The Company evaluates securities on a quarterly basis including changes in security ratings issued by ratings agencies, changes in 
the financial condition of the issuer, and, for mortgage-related and asset-backed securities, delinquency and loss information with
respect  to  the  underlying  collateral,  changes  in  the  levels  of  subordination  for  the  Company’s  particular  position  within  the 
repayment structure, and remaining credit enhancement as compared to expected credit losses of the security.  Substantially all of 
these securities continue to be investment grade rated by one or more major rating agencies. 

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, 2011.

The fair values of the investment securities could decline in the future if the general economy deteriorates, 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,  2011,  $903,807  thousand  of  investment  securities  were  pledged  to  secure  public  deposits  and  short-term 
funding needs, compared to $898,124 thousand at December 31, 2010.

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.” If the Bank becomes aware of deterioration in a borrower’s performance or financial condition between 
Loan Review examinations, assigned risk grades will be re-evaluated promptly. Credit risk grades assigned by the Loan Review 
Department are subject to review by the Bank’s regulatory authority during regulatory examinations.  

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

payment terms extending maturity dates to allow for deferred principal repayment. All loans were performing in accordance with 
their restructured terms at December 31, 2011. There were no troubled debt restructurings during the year ended December 31, 
2010. 

The  Company  pledges  loans  to  secure  borrowings  from  the  Federal  Home  Loan  Bank  (FHLB).  At  December  31,  2011,  loans 
pledged to secure borrowing totaled $69,145 thousand compared with $137,954 thousand at December 31, 2010. The FHLB does 
not have the right to sell or repledge such loans. 

There were no loans held for sale at December 31, 2011 and December 31, 2010.  

Note 5: Concentration of Credit Risk

The  Company’s  business  activity  is  with  customers  in  Northern  and  Central  California.  The  loan  portfolio  is  well  diversified 
within  the  Company’s  geographic  market,  although  the  Company  has  significant  credit  arrangements  that  are  secured  by  real 
estate  collateral.  In  addition  to  real  estate  loans  outstanding  as  disclosed  in  Note  4,  the  Company  had  loan  commitments  and 
standby letters of credit related to real estate loans of $2,935 thousand and $13,048 thousand at December 31, 2011 and 2010, 
respectively. The Company requires collateral on all real estate loans with loan-to-value ratios generally no greater than 75% on 
commercial real estate loans and no greater than 80% on residential real estate loans at origination.

Note 7: Goodwill and Identifiable Intangible Assets

The Company has recorded goodwill and other identifiable intangibles associated with purchase business combinations. Goodwill 
is not amortized, but is periodically evaluated for impairment. The Company did not recognize impairment during the years ended
December 31, 2011 and December 31, 2010. Identifiable intangibles are amortized to their estimated residual values over their 
expected  useful  lives.  Such  lives  and  residual  values  are  also  periodically  reassessed  to  determine  if  any  amortization  period 
adjustments  are  indicated.  During  the  year  ended  December  31,  2011  and  December  31,  2010,  no  such  adjustments  were 
recorded.

Note 9: Shareholders’ Equity

On February 13, 2009, the Company issued to the United States Department of the Treasury (the “Treasury”) 83,726 shares of 
Series A Fixed Rate Cumulative Perpetual Preferred Stock (the “Series A Preferred Stock”), having a liquidation preference of 
$1,000 per share. The structure of the Series A Preferred Stock included cumulative dividends at a rate of 5% per year for the first 
five years and thereafter at a rate of 9% per year. On September 2, 2009 and November 18, 2009, the Company redeemed 41,863 
shares and 41,863 shares, respectively, of its Series A Preferred Stock at $1,000 per share. Prior to redemption, under the terms of 
the Series A Preferred Stock, the Company could not declare or pay any dividends or make any distribution on its common stock, 
other  than  regular  quarterly  cash  dividends  not  exceeding  $0.35  per  share  or  dividends  payable  only  in  shares  of  its  common 
stock, or repurchase its common stock or other equity or capital securities, other than in connection with benefit plans consistent 
with  past  practice  and  certain  other  circumstances  specified  in  the  Securities  Purchase  Agreement  with  the  Treasury.  The 
Treasury, as part of the preferred stock issuance, received a warrant to purchase 246,640 shares of the Company’s common stock 
at an exercise price of $50.92 per share. The proceeds from Treasury were allocated based on the relative fair value of the warrant
as  compared  with  the  fair  value  of  the  preferred  stock.  The  fair  value  of  the  warrant  was  determined  using  a  valuation  model 
which incorporates assumptions including the Company’s common stock price, dividend yield, stock price volatility, the risk-free
interest rate, and other assumptions. The Company allocated $1,207 thousand of the proceeds from the Series A Preferred Stock 
to the warrant. The discount on the preferred stock was accreted to par value during the term the Series A Preferred Stock was 
outstanding, and reported as a reduction to net income applicable to common equity over that period. 

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 amended and restated in 2003. Stock options are granted with an 
exercise price equal to the fair market value of the related common stock on the grant date and generally become exercisable in
equal annual installments over a three-year period with each installment vesting on the anniversary date of the grant. Each stock
option has a maximum ten-year term. A restricted performance share grant becomes vested after three years of being awarded, 
provided the Company has attained its performance goals for such three-year period.

The  Company  applies  the  Roll-Geske  option  pricing  model  (Modified  Roll)  to  determine  grant  date  fair  value  of  stock  option 
grants. This model modifies the Black-Scholes Model to take into account dividends and American options. During the twelve 
months ended December 31, 2011, 2010 and 2009, the Company granted 275 thousand, 296 thousand, and 246 thousand stock 
options, respectively. The following weighted average assumptions were used in the option pricing to value stock options granted

In  December  1986,  the  Company  declared  a  dividend  distribution  of  one  common  share  purchase  right  (the  “Right”)  for  each 
outstanding share of common stock. The Rights expired on December 31, 2009. 

Note 10: Risk-Based Capital 

The  Company  and  the  Bank  are  subject  to  various  regulatory  capital  adequacy  requirements  administered  by  federal  and  state 
agencies.  The  Federal  Deposit  Insurance  Corporation  Improvement  Act  of  1991  (“FDICIA”)  required  that  regulatory  agencies 
adopt  regulations  defining  five  capital  tiers  for  banks:  well  capitalized,  adequately  capitalized,  undercapitalized,  significantly
undercapitalized and critically undercapitalized. Failure to meet minimum capital requirements can initiate discretionary actions
by  regulators  that,  if  undertaken,  could  have  a  direct,  material  effect  on  the  Company’s  financial  statements.  Quantitative 

73

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
measures, established by the regulators to ensure capital adequacy, require that the Company and the Bank maintain minimum 
ratios of capital to risk-weighted assets. There are two categories of capital under the guidelines. Tier 1 capital includes common 
shareholders’ equity and qualifying preferred stock less goodwill, identifiable intangible assets, and other adjustments including 
the  unrealized  net  gains  and  losses,  after  taxes,  on  available  for  sale  securities.  Tier  2  capital  includes  preferred  stock  not
qualifying for Tier 1 capital, mandatory convertible debt, subordinated debt, certain unsecured senior debt and the allowance for 
loan  losses,  subject  to  limitations  within  the  guidelines.  Under  the  guidelines,  capital  is  compared  to  the  relative  risk  of  the
balance sheet, derived from applying one of four risk weights (0%, 20%, 50% and 100%) to various categories of balance sheet 
assets and unfunded commitments to extend credit, primarily based on the credit risk of the counterparty. The capital amounts and
classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. 

As of December 31, 2011, the Company and the Bank met all capital adequacy requirements to which they are subject. 

The most recent notification from the Federal Reserve Board categorized the Company and the Bank as well capitalized under the 
FDICIA  regulatory  framework  for  prompt  corrective  action.  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. Since that notification, there 
are no conditions or events that Management believes have changed the risk-based capital category of the Company or the Bank. 

The following tables show capital ratios for the Company and the Bank as of December 31, 2011 and 2010:

Note 11: 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 bases and operating loss and tax credit 
carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the 
years in which those temporary differences are expected to be recovered or settled. Amounts for the current year are based upon
estimates and assumptions as of the date of these financial statements and could vary significantly from amounts shown on the tax
returns as filed. 

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

Based on Management’s judgment, a valuation allowance is not needed to reduce the gross deferred tax asset because it is more 
likely than not that the gross deferred tax asset will be realized through recoverable taxes or future taxable income. In making
such determination, Management considered future income from FDIC indemnification payments that will be realized as losses 
on acquired assets are realized. Net deferred tax assets are included with interest receivable and other assets in the Consolidated
Balance Sheets.

2010 

The Company does not anticipate any significant increase or decrease in unrecognized tax benefits during 2012. Unrecognized tax
benefits at December 31, 2011 and 2010 include accrued interest and penalties of $43 thousand and $26 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, 2011, 2010, 2009 and 2008 remain subject to examination by the Internal Revenue Service. The tax years ended December 
31, 2011, 2010, 2009, 2008 and 2007 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 12: 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 certain loans held for 
investment  and  other  assets.    These  nonrecurring  fair  value  adjustments  typically  involve  the  lower-of-cost-or-fair  value 
accounting or impairment or write-down 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.  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. 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 federal agency securities, which are traded by dealers or brokers in 
active markets.  Valuations are obtained from readily available pricing sources for market transactions involving identical assets
or liabilities. 

Level 2 – Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar 
instruments  in  markets  that  are  not  active,  and  model-based  valuation  techniques  for  which  all  significant  assumptions  are 
observable in the market. Level 2 includes mortgage-backed securities, municipal bonds and residential collateralized mortgage 
obligations as well as other real estate owned and impaired loans collateralized by real property where the fair value is generally
based upon independent market prices or appraised values of the collateral.  

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.
Level  3  includes  those  impaired  loans  collateralized  by  business  assets  where  the  expected  cash  flow  has  been  used  in 
determining the fair value.

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-market  accounting  or  write-
downs of individual assets. For assets measured at fair value on a nonrecurring basis that were still held in the balance sheet at 
December 31, 2011 and 2010, 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.

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. 

Cash  and  Due  from  Banks    The  carrying  amount  of  cash  and  amounts  due  from  banks  approximate  fair  value  due  to  the 
relatively short period of time between their origination and their expected realization. 

Money Market Assets  The carrying amount of money market assets approximate fair value due to the relatively short period of 
time between their origination and their expected realization. 

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 
$32,597 thousand at December 31, 2011 and $35,636 thousand at December 31, 2010 and the fair value discount due to credit 
default  risk  associated  with  purchased  covered  and  purchased  non-covered  loans  of  $46,282  thousand  and  $10,211  thousand, 
respectively  at  December 31,  2011  and purchased  covered  and  purchased non-covered  loans  of $61,784  thousand and  $32,382 
thousand, respectively at December 31, 2010 were applied against the estimated fair values to recognize estimated future defaults
of contractual cash flows. The Company does not consider these values to be a liquidation price for the loans. 

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

Deposit Liabilities  The carrying amount of checking accounts, savings accounts and money market accounts approximates fair 
value due to the relatively short period of time between their origination and their expected realization.  The fair values of time 
deposits  were  estimated  by  discounting  estimated  future  cash  flows  related  to  these  financial  instruments  using  current  market 
rates for financial instruments with similar characteristics. 

Short-Term  Borrowed  Funds    The  carrying  amount  of  securities  sold  under  agreement  to  repurchase  and  other  short-term 
borrowed  funds  approximate  fair  value  due  to  the  relatively  short  period  of  time  between  their  origination  and  their  expected 
realization.  The fair values of term repurchase agreements were estimated by using interpolated yields for financial instruments
with similar characteristics. 

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

Federal  Home  Loan  Bank  Advances    The  fair  values  of  FHLB  advances  were  estimated  by  using  interpolated  yields  for 
financial instruments with similar characteristics. 

Debt Financing and Notes Payable  The fair values of debt financing and notes payable were estimated by using interpolated 
yields for financial instruments with similar characteristics. 

Restricted Performance Share Grants The fair value of liabilities for unvested restricted performance share grants recorded in 
Other Liabilities were estimated using quoted prices as described above for Level 1 valuation.

The table below is a summary of fair value estimates for financial instruments, excluding financial instruments recorded at fair
value  on  a  recurring  basis.  The  values  assigned  do  not  necessarily  represent  amounts  which  ultimately  may  be  realized.  In 
addition, these values do not give effect to discounts to fair value which may occur when financial instruments are sold 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 13: Lease Commitments 

Thirty-three  banking  offices  and  a  centralized  administrative  service  center  are  owned  and  seventy-four  facilities  are  leased. 
Substantially  all  the  leases  contain  multiple  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 are as follows: 

2012 ...................................................................................................................  
2013 ...................................................................................................................

The  total  minimum  lease  payments  have  not  been  reduced  by  minimum  sublease  rentals  of  $8,554  thousand  due  in  the  future 
under noncancelable subleases. Total rentals for premises, net of sublease income, included in noninterest expense were $7,759 
thousand  in  2011,  $6,862  thousand  in  2010  and  $7,196  thousand  in  2009.  During  2009,  the  Company  was  obligated  to  pay 
monthly lease payments on County facilities until vacated.

Note 14: 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 $348,621 thousand and $422,677 thousand at December 31, 2011 and 2010, 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. Standby letters of credit outstanding totaled $27,221 thousand and $25,458 thousand at 
December 31, 2011 and 2010, respectively. The Company also had commitments for commercial and similar letters of credit of 
$454 thousand and $3,351 thousand at December 31, 2011 and 2010, respectively. 

During 2007, the Visa Inc. (“Visa”) organization of affiliated entities announced that it completed restructuring transactions in
preparation for an initial public offering planned for early 2008, and, as part of those transactions, the Bank’s membership interest 
in Visa U.S.A. was exchanged for an equity interest in Visa Inc., in the form of Class B common stock. In accordance with Visa’s
by-laws, the Bank and other Visa U.S.A. member banks are obligated to share in Visa’s litigation obligations which existed at the
time of the restructuring transactions. A litigation escrow account is maintained by Visa for these obligations. When Visa funds
the  litigation  escrow  account,  the  Class  B  common  shares  become  convertible  into  fewer  Class  A  common  shares  through  a 
corresponding adjustment to the conversion rate applicable to the Class B common shares. 

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 costs related to covered assets are eighty percent indemnified under loss-sharing agreements with the FDIC if
certain conditions are met.

Note 15: Retirement Benefit Plans

The Company sponsors a 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 benefits provided by the Deferred Profit-
Sharing Plan were $1,200 thousand in 2011, $1,740 thousand in 2010 and $1,176 thousand in 2009. 

In  addition  to  the  Deferred  Profit-Sharing  Plan,  all  salaried  employees  are  eligible  to  participate  in  the  Tax  Deferred 
Savings/Retirement Plan (ESOP) upon completion of a 90-day introductory period. The Tax Deferred Savings/ Retirement Plan 
(ESOP)  allows  employees  to  defer,  on  a  pretax  basis,  a  portion of  their  salaries  as  contributions  to  this  Plan.  Participants  may
invest  in  several  funds,  including  one  fund  that  invests  exclusively  in  Westamerica  Bancorporation  stock.  The  matching 
contributions charged to compensation expense were $1,283 thousand in 2011, $1,377 thousand in 2010 and $1,353 thousand in 
2009. 

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’  insurance 
premiums which are determined at their date of retirement. The Company reimburses a portion of Medicare Part B premiums for 
all qualifying retirees over age 65 and 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.  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 above discount rate is based on the Corporate AA Moody’s bond 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,  which  is  considered  in 
estimating the increase in the cost of providing such benefits. The assumed annual average rate of inflation used to measure the 
expected cost of benefits covered by the plan was 4.50% for 2012 and beyond.

Note 16: Related Party Transactions 

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

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

Note 17: Regulatory Matters 

Payment of dividends to the Company by the Bank is limited under regulations for state chartered banks. The amount that can be 
paid  in  any  calendar  year,  without  prior  approval  from  regulatory  agencies,  cannot  exceed  the  net  profits  (as  defined)  for  the 
preceding  three  calendar  years  less  dividends  paid.  Under  this  regulation,  the  Bank  was  not  required  to  obtain  approval  for 
dividends paid to the Company during 2011. The Company consistently has paid quarterly dividends to its shareholders since its 
formation in 1972. As of December 31, 2011, $166,437 thousand was available for payment of dividends by the Company to its 
shareholders. 

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 $314,980 thousand in 2011 and $215,609 thousand in 2010, 
which amounts meet or exceed the Bank’s required reserves.

Note 19: 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 applicable to common equity by the average number of common shares outstanding during the 
period. Diluted earnings per common share are computed by dividing net income applicable to common equity by the average 
number of common shares outstanding during the period plus the impact of common stock equivalents.

For the years ended December 31, 2011, 2010, and 2009, options to purchase 1,553 thousand, 380 thousand and 788 thousand 
shares  of  common  stock,  respectively,  were  outstanding  but  not  included  in  the  computation  of  diluted  earnings  per  common 
share  because  the  option  exercise  price  exceeded  the  fair  value  of  the  stock  such  that  their  inclusion  would  have  had  an  anti-
dilutive effect.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders 
Westamerica Bancorporation:  

We have audited the accompanying consolidated balance sheets of Westamerica Bancorporation and subsidiaries (the Company) 
as  of  December  31,  2011  and  2010,  and  the  related  consolidated  statements  of  income,  changes  in  shareholders’  equity  and 
comprehensive  income,  and  cash  flows  for  each  of  the  years  in  the  three-year  period  ended  December  31,  2011.  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, 2011 and 2010, and the results of their operations and their 
cash flows for each of the years in the three-year period ended December 31, 2011, in conformity with U.S. generally accepted 
accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
Company’s internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control-
Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO),  and  our 
report  dated  February  27,  2012  expressed  an  unqualified  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over 
financial reporting.

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

None.  

ITEM 9A. CONTROLS AND PROCEDURES

The  Company’s  principal  executive  officer  and  principal  financial  officer  have  evaluated  the  effectiveness  of  the  Company’s 
“disclosure  controls  and  procedures,”  as  such  term  is  defined  in  Rule  13a-15(e)  of  the  Securities  Exchange  Act  of  1934,  as 
amended, as of December 31, 2011. 

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,  2011  that  has 
materially  affected,  or  is  reasonably  likely  to  materially  affect,  the  Company’s  internal  control  over  financial  reporting. 
Management’s Report on Internal Control Over Financial Reporting and the attestation Report of Independent Registered Public 
Accounting Firm are found on pages 45-46, immediately preceding the financial statements.
