PART I
ITEM 1. BUSINESS
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 Company also owns 100% of the capital stock of Community Banker Services Corporation, 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 additional 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 business combinations were accounted for as poolings-of-interests.
In August, 2000, the Company acquired First Counties Bank. The acquisition was valued at approximately $19.7 million and was accounted for using the purchase accounting method. The assets and liabilities of First Counties Bank were fully merged into WAB in September 2000. First Counties Bank had $91 million in assets and offices in Lake, Napa, and Colusa counties.
In June of 2002 the Company acquired Kerman State Bank. The acquisition was valued at approximately $14.6 million and was accounted for using the purchase accounting method. The assets and liabilities of Kerman State Bank were fully merged into WAB immediately upon consummation of the merger. Kerman State Bank had $95 million in assets and three offices in Fresno county.
On March 1, 2005, the Company acquired Santa Rosa based Redwood Empire Bancorp, the parent company of National Bank of the Redwoods (NBR). The acquisition was valued at approximately $153 million and was accounted for using the purchase accounting method. The assets and liabilities of NBR were fully merged into WAB as of close of business day on March 11, 2005. As of March 1, 2005, NBR had approximately $440 million in loans and $370 million in deposits.
At December 31, 2006, the Company had consolidated assets of approximately $4.8 billion, deposits of approximately $3.5 billion and shareholders’ equity of approximately $424.2 million. The Company and its subsidiaries employed approximately 890 full-time equivalent staff as of December 31, 2006.
The Company makes available free of charge its 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 as soon as reasonably practicable after they are electronically filed with or furnished to the Securities and Exchange Commission (“SEC”) through its website (http://www.westamerica.com). Such documents are also available through the SEC’s website (http://www.sec.gov). Requests for the Form 10-K annual report, as well as the Company’s director, officer and employee Code of Conduct and Ethics, can also be submitted to:

Supervision and Regulation
The following is not intended to be an exhaustive description of the statutes and regulations applicable to the Company’s or the Bank’s business. The description of statutory and regulatory provisions is qualified in its entirety by reference to the particular statutory or regulatory provisions. Moreover, major new legislation and other regulatory changes affecting the Company, the Bank, banking, 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 costs of any examination by the FRB are payable by the Company. 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, which became effective on April 1, 2003. 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.
On March 11, 2000, the Gramm-Leach-Bliley Act (the “GLBA”), or the Financial Services Act of 1999 became effective. The GLBA 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 though 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 new 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.
Under the GLBA, Federal Reserve member banks, subject to various requirements, as well as national banks, are permitted to engage through “financial subsidiaries” in certain financial activities permissible for affiliates of FHCs. However, to be able to engage in such activities the Bank must also be well capitalized and well managed and have received at least a “satisfactory” rating in its most recent Community Reinvestment Act examination. The Company cannot be certain of the future effect of the foregoing legislation on its business, although there is likely to be consolidation among financial services institutions and increased competition for the Company.

Regulation and Supervision of Banks
The Bank is a California state-chartered bank, is insured by the Federal Deposit Insurance Corporation (the “FDIC”) and is a member bank of the Federal Reserve System. As such, the Bank is subject to regulation, supervision and regular examination by the California Department of Financial Institutions (“DFI”) and the FRB. As a member bank of the Federal Reserve System, the Bank’s primary federal regulator is the FRB. The regulations of these agencies affect most aspects of the Bank’s business and prescribe permissible types of loans and investments, the amount of required reserves, requirements for branch offices, the permissible scope of its activities and various other requirements.
In addition to federal banking law, the Bank is also subject to applicable provisions of California law. Under California law, the Bank is subject to various restrictions on, and requirements regarding, its operations and administration including the maintenance of branch offices and automated teller machines, capital requirements, deposits and borrowings, shareholder rights and duties, and investment and lending activities.
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. However, because the Bank is a member of the Federal Reserve System, its investment authority is limited by regulations promulgated by the FRB. 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.
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 reported on the balance sheet as assets, and transactions 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, 2006, 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.
Prompt Corrective Action and Other Enforcement Mechanisms
FDICIA requires each federal banking agency to take prompt corrective action to resolve the problems of insured depository institutions, including but not limited to those that fall below one or more prescribed minimum capital ratios.
An institution that, based upon its capital levels, is classified as “well capitalized,” “adequately capitalized” or “undercapitalized” may be treated as though it were in the next lower capital category if the appropriate federal banking agency, after notice and opportunity for hearing, determines that an unsafe or unsound condition or an unsafe or unsound practice warrants such treatment. At each successive lower capital category, an insured depository institution is subject to more restrictions. In addition to measures taken under the prompt corrective action provisions, commercial banking organizations may be subject to potential enforcement actions by the federal banking agencies for unsafe or unsound practices in conducting their businesses or for violations of any law, rule, regulation or any condition imposed in writing by the agency or any written agreement with the agency.

Safety and Soundness Standards
FDICIA 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 to 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 ultimately 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 collectibility 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 and Assessments for Examinations
The Bank’s deposits are insured by the Bank Insurance Fund (BIF) administered by the FDIC. FDICIA established several mechanisms to increase funds to protect deposits insured by the BIF administered by the FDIC. The FDIC is authorized to borrow up to $30 billion from the United States Treasury; up to 90% of the fair market value of assets of institutions acquired by the FDIC as receiver from the Federal Financing Bank; and from depository institutions which are members of the BIF. Any borrowings not repaid by asset sales are to be repaid through insurance premiums assessed to member institutions. Such premiums must be sufficient to repay any borrowed funds within 15 years and provide insurance fund reserves of $1.25 for each $100 of insured deposits. FDICIA also provides authority for special assessments against insured deposits.

Congress adopted the Federal Deposit Insurance Reform Act of 2005 as part of the Deficit Reduction Act of 2005 and President Bush signed it on February 8, 2006 and a companion bill, the Federal Deposit Insurance Reform Conforming Amendments Act of 2005, on February 15, 2006. This legislation provides for:
- merging the BIF and SAIF deposit insurance funds;
- annually adjusting the minimum insurance fund reserve ratio between $1.15 and $1.50 per $100 of insured deposits;
- increasing deposit coverage for retirement accounts to $250,000,
- indexing the insurance level for inflation, with any increases approved by the FDIC and National Credit Union Administration on a five-year cycle beginning in 2010 after review of the state of the deposit insurance fund and related factors;
- credits of up to $4.7 billion to offset premiums for banks that capitalized the FDIC by 1996; and
- an historical basis concept for distributing credits and dividends to reflect past contributions to the insurance funds.
In the fourth quarter of 2006, the FDIC adopted two final rules implementing the Federal Deposit Insurance Reform Act of 2005. One rule creates a new system for risk- based assessments and sets assessment rates beginning January 1, 2007. Assessment rates are three basis points above the base rates, ranging from 5 to 7 basis for Risk Category I institutions, 10 basis points for Risk Category II institutions, 28 basis points for Risk Category III institutions, and 43 basis points for Risk Category IV institutions. The Bank is categorized as a Risk Category I institution. The other rule sets the designated reserve ratio at 1.25 percent. In October of 2006, FDIC’s Board adopted a final rule governing the distribution and use of the $4.7 billion one-time assessment credit and a temporary final rule that expires at the end of 2009 governing dividends from the insurance fund. The Bank had assessment credits of approximately $5 million as of December 31, 2006.
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
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 FRB adopted such regulations with an effective date of November 13, 2000, and a date of full compliance with the regulations on July 1, 2001. The Bank is subject to the FRB’s regulations.
Customer Information Security
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
On October 26, 2001, the President signed into law the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 or the “USA Patriot Act.” Title III of the 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.

Table of Contents

The provisions of Title III of the USA Patriot Act which affect banking organizations, including 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 immediately impose any new filing or reporting obligations for banking organizations, but does require certain additional due diligence and recordkeeping practices. Some requirements take effect without the issuance of regulations. Other provisions were implemented through regulations promulgated by the U.S. Department of the Treasury, in consultation with the FRB and other federal financial institutions regulators.
Sarbanes-Oxley Act of 2002
On July 30, 2002, the U.S. Congress enacted the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”). The stated goals of 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 new corporate governance rules, requires 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 oversee 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.
Given the extensive role of the SEC, the PCAOB and the Exchanges in implementing rules relating to Sarbanes-Oxley’s new requirements, the federalization of certain elements traditionally within the sphere of state corporate law, the impact of Sarbanes-Oxley on reporting companies have been and will continue to be significant.
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 high level of enforcement and compliance-related activities of federal and state authorities will continue and potentially increase.
Competition
In the past, WAB’s principal competitors for deposits and loans have been other banks (particularly major 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, and it is anticipated that this trend will continue.

The enactment of the Interstate Banking and Branching Act in 1994 and the California Interstate Banking and Branching Act of 1995 have increased competition within California. Regulatory reform, as well as other changes in federal and California law will also affect competition. While the future impact of these changes, and of other proposed changes, cannot be predicted with certainty, it is clear that the business of banking in California will remain highly competitive.
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. As an active participant in the financial markets, the Company believes that it continually adapts to these changing competitive conditions.
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 and Liability Management” and “- Liquidity” and “Item 7A Quantitative and Qualitative Disclosures About Market Risk” is incorporated by reference in this paragraph. The Bank’s income and cash flow depend to a great extent on the difference between the interest earned on loans and investment securities, the interest paid on deposits and other borrowings and the Company’s success in competing for deposits. The Company cannot control or prevent changes in the level of interest rates. They fluctuate in response to general economic conditions and the policies of various governmental and regulatory agencies, in particular, the FRB. Changes in monetary policy, including changes in interest rates, will influence the origination of loans, the purchase of investments, the generation of deposits and the rates received on loans and investment securities and paid on deposits and other liabilities.
Risks Related to the Nature and Geographical Location of the Company’s Business
The Bank 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 Bank’s business is located in California. A portion of the loan portfolio of the Company is dependent on real estate. At December 31, 2006, real estate served as the principal source of collateral with respect to approximately 59% of the Bank’s loan portfolio. The Bank’s financial condition and operating results will be subject to changes in economic conditions in California. In the early to mid-1990s, California experienced a significant and prolonged downturn in its economy, which adversely affected financial institutions. Economic conditions in California are subject to various uncertainties at this time, including the decline in the technology sector, 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 effect the Bank.

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 Bank’s loans are located in California. California is a state which is prone to earthquakes, brush fires, flooding 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 Bank 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, fire or other natural disaster in California could have a material adverse effect on the Bank’s business, financial condition, results of operations and cash flows.
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 its bank and nonbank subsidiaries. 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 Bank’s customers and not for the benefit of investors. In the past, the Bank’s business has been materially affected by these regulations. This trend is likely to continue in the future. 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 legislative and regulatory reactions to the terrorist attack on September 11, 2001 and future acts of terrorism, and major U.S. corporate bankruptcies and reports of accounting irregularities at U.S. public companies.
Additionally, the Bank’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, and (c) 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.
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 customer relationship management and systems. 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. 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.
Shares of Company common stock eligible for future sale 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 30.5 million were outstanding at December 31, 2006. Pursuant to its stock option plans, at December 31, 2006, the Company had exercisable options outstanding of 3.1 million. As of December 31, 2006, 1.4 million shares of Company common stock remained available for grants under the Company’s stock option plans (and stock purchase plan). Sales of substantial amounts of Company common stock in the public market could adversely affect the market price of its common stock.
ITEM 1B. UNRESOLVED STAFF COMMENTS

ITEM 2. PROPERTIES
Branch Offices and Facilities
WAB is engaged in the banking business through 87 offices in 21 counties in Northern and Central California including 13 offices in Fresno County, 11 each in Marin and Sonoma Counties, seven in Napa County, five each in Stanislaus, Lake, Kern, Contra Costa and Solano Counties, three each in Alameda and Sacramento Counties, two each in Mendocino, Nevada, Placer and Tulare Counties, and one each in Merced, San Francisco, Tuolumne, Kings, Madera, and Yolo Counties. WAB believes all of its offices are constructed and equipped to meet prescribed security requirements.
The Company owns 28 branch office locations and one administrative facility and leases 69 facilities. Most of the leases contain multiple renewal options and provisions for rental increases, principally for changes in the cost of living index, 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, except 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.
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
There were no matters submitted to a vote of the shareholders during the fourth quarter of 2006.

As of February 5, 2007, there were approximately 8,200 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, 2006, $186.4 million was allowable as for payment of dividends by the Company to its shareholders, under applicable laws and regulations.
See Notes 10, 17, 19 and 20 to the consolidated financial statements included in this report for 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 terms of the Rights were most recently amended and restated in 2004. The amended plan is very similar in purpose and effect to the plan as it existed prior to this amendment, aimed at helping the Board of Directors to maximize shareholder value in the event of a change of control of the Company and otherwise resist actions that the Board considers likely to injure the Company or its shareholders.

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 40 through 67, 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 management 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. 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 to be the accounting area that requires the most subjective or complex judgments, and as such could be most subject to revision as new information becomes available.
The Allowance for Loan Losses represents management’s estimate of the amount of loss in the loan portfolio that can be reasonably estimated as of the balance sheet date. Determining the amount of the Allowance for Loan Losses is considered a critical accounting estimate because it requires significant judgment and the use of estimates related to the amount and timing of expected future cash flows on impaired loans, estimated losses on pools of homogeneous loans based on historical loss experience, and consideration of current economic trends, uncertainties and conditions, all of which may be susceptible to significant change. A discussion of the factors driving changes in the amount of the Allowance for Loan losses is included in the “Credit Quality” discussion below.
Acquisition
Effective March 1, 2005, the Company acquired Redwood Empire Bancorp (“REBC”), parent company of National Bank of the Redwoods. The REBC acquisition was accounted for using the “purchase method” of accounting for business combinations which requires valuing assets and liabilities which do not have quoted market prices. In determining fair values for assets and liabilities without quoted market prices, management engaged an independent consultant to determine such fair values. Critical assumptions used in the valuation included prevailing market interest rates on similar financial products, future cash flows, maturity structures and durations of similar financial products, the cost of processing deposit products, the interest rate structure for similar funding sources over the estimated duration of acquired deposits, the duration of customer relationships, and other critical assumptions.
The acquisition of REBC was completed on March 1, 2005, followed by a divestiture of a former REBC branch in Lake County in the second quarter of 2005. After adjusting for the divestiture the transaction was valued at approximately $150 million, including approximately $57 million paid in cash, issuance of approximately 1.6 million shares of the Company’s common stock, and conversion of Redwood Empire stock options into Company stock options based on an average stock price of $51.84. REBC, on March 1, 2005, had approximately $440 million in loans, $370 million in deposits, $20 million in “trust preferred” subordinated debt, and $30 million of shareholders’ equity. Goodwill of $103 million and identifiable intangibles of $27 million were recorded in accordance with the purchase method of accounting for business combinations. During the second quarter of 2005, the Company sold a former REBC branch with approximately $34 million in deposits, as required by the FRB in connection with its approval of the REBC acquisition. The premium on the sale of the branch was recorded as a reduction of goodwill associated with the purchase of REBC.

Net Income
The Company reported net income for 2006 of $98.8 million or $3.11 diluted earnings per share, compared with net income of $106.0 million, or $3.22 diluted earnings per share for 2005. The 2005 results included a $3.7 million gain on sale of real estate, $945 thousand in tax-exempt life insurance proceeds, and $4.9 million in securities losses which, on a combined basis, increased net income $247 thousand.

Net income in 2006 was $7.2 million or 6.8% less than in 2005 attributable to lower net interest income (FTE), partially offset by higher noninterest income and decreases in provision for credit losses, noninterest expense and income tax provision (FTE). The decrease in net interest income (FTE) (down $19.2 million or 8.6%) was the net result of lower average interest-earning assets and higher funding costs, partially offset by higher yields on earning assets. The credit loss provision decreased $455 thousand or 50.6% from a year ago, reflecting Management’s assessment of credit risk for the loan portfolio. Noninterest income increased $807 thousand or 1.5%. Noninterest expense decreased $5.5 million or 5.2% largely due to lower personnel costs. The provision for income taxes (FTE) decreased $5.1 million or 8.0% primarily due to lower profitability, higher tax credits and refunds, and other tax preference items.
Net income for 2005 increased $12.8 million, or 13.7%, over net income for 2004. Results for 2005 benefited from the March 1, 2005 acquisition of REBC, which generally increased the base of earning assets, increased noninterest income (particularly merchant credit card fees), and increased noninterest expenses (particularly amortization of intangibles, occupancy, and furniture and equipment). Net interest income (FTE) increased $5.9 million or 2.7%, mainly due to earning asset growth, partially offset by a reduced net interest margin resulting from rates paid on interest-bearing liabilities rising faster than yields on earning assets. The loan loss provision declined $1.8 million, year over year, in accordance with Management’s assessment of credit risk for the loan portfolio. Noninterest income increased $16.0 million primarily due to a $5.6 million increase in merchant credit card income, a $3.7 million gain on sale of real estate and $945 thousand in life insurance proceeds, partially reduced by $4.9 million in realized securities losses. Furthermore, 2004 results included a $7.2 million securities impairment writedown, a $2.2 million loss on extinguishment of debt, and $2.2 million in realized investment securities gains. Noninterest expense increased $5.2 million or 5.0% mostly due to an increase in occupancy and equipment expense and amortization of intangibles relating to the REBC acquisition. Income tax provision (FTE) increased $5.7 million or 9.7% due to higher pretax income, partially offset by the tax-exempt nature of life insurance proceeds.
The Company’s return on average total assets was 2.01% in 2006, compared to 2.09% and 2.06% in 2005 and 2004, respectively. Return on average equity in 2006 was 23.38%, compared to 25.70% and 28.23% in 2005 and 2004, respectively.

Net Interest Income
The Company’s primary source of revenue is net interest income, or the difference between interest income on earning assets and interest expense on interest-bearing liabilities. Net interest income (FTE) in 2006 decreased $19.2 million or 8.6% from 2005, to $204.7 million. Comparing 2005 to 2004, net interest income (FTE) increased $5.9 million or 2.7%.

Interest and fee income (FTE) increased in 2006 by $2.5 million or 0.9% from 2005, the net result of higher yields on earning assets and higher loan fees (up $447 thousand), partially offset by lower average investments. The average yield on earning assets excluding loan fees in 2006 was 5.99% compared with 5.73% in 2005. The loan portfolio yield excluding loan fees for 2006 compared with 2005 was higher by 33 bp, due to increases in rates charged on commercial loans (up 74 bp), construction loans (up 188 bp), consumer credit lines (up 165 bp), indirect consumer loans (up 31 bp), residential real estate loans (up 16 bp) and commercial real estate loans (up 4 bp). The investment portfolio yield rose by 11 bp. The increase resulted from higher yields on U.S. government sponsored entity obligations (up 18 bp), partially offset by lower yields on municipal securities (down 12 bp). The decline in yields on municipal securities is due to maturity or call payments generally attributable to securities with relatively high interest coupons. Average earning assets decreased $166 million or 3.6% in 2006 compared with the previous year. Investments declined $167 million due to decreases in average balances of U.S. government sponsored entity obligations (down $140 million), municipal securities (down $18 million) and preferred stock and corporate securities (down $8 million). The loan portfolio grew $428 thousand due to increases in average balances of residential real estate loans (up $33 million), commercial real estate loans (up $10 million) and construction loans (up $7 million), partially offset by decreases in average balances of commercial loans (down $36 million) and consumer credit lines (down $13 million).
Interest expense increased by $21.6 million or 49.5% in 2006, due to rising rates paid on interest-bearing liabilities and a $19 million increase in certificate of deposits (“CDs”) and an increase in other short-term borrowings. Rates paid on liabilities averaged 2.11% in 2006 compared to 1.36% in 2005. Rates on most interest-bearing liabilities moved up with the general trend in the market. The average rate on federal funds purchased rose 178 bp. Rates on most deposits were also higher: CDs over $100 thousand which rose 159 bp, retail CDs which increased by 70 bp, and money market savings accounts which increased by 13 bp. Interest-bearing liabilities declined $127 million or 3.9% over the prior year mostly due to lower average balances of federal funds purchased (down $25 million), retail CDs (down $41 million) and money market savings (down $128 million). These decreases were partially offset by increases in average balances of CDs over $100 thousand (up $60 million) and other short term borrowings (up $43 million).
Interest and fee income (FTE) increased in 2005 by $28.4 million or 11.9% from 2004, the net result of growth of average earning assets, primarily due to the REBC acquisition, and higher yields on earning assets, partially offset by the effect of one less accrual day. Average earning assets grew $406.4 million, with loans and investments increasing $317.9 million and $88.5 million, respectively. Most growth in average loans was concentrated in commercial, construction, commercial real estate and residential real estate credits, which increased $41 million, $31 million, $137 million and $118 million, respectively. The increase in average investment balances was due to growth in municipal securities (up $131 million), partially offset by declines in U.S. government sponsored entity obligations (down $11 million) and corporate and other securities (down $31 million). The yield on earning assets, excluding loan fee income, rose from 5.61% in 2004 to 5.73% in 2005. The composite yield on loans, excluding loan fee income, increased 12 basis points (“bp”) to 6.19% in 2005. Yield increases on commercial loans (up 76 bp) and personal credit lines (up 141 bp) were partially reduced by declining yields on commercial real estate loans (down 20 bp) and indirect consumer loans (down 38 bp). The yield on the investment portfolio increased 8 bp mainly due to a 16 bp increase in mortgage backed securities and collateralized mortgage obligations, partially offset by a 33 bp decline in municipal securities.
Interest expense increased in 2005 to $43.6 million, due to rising rates paid on interest-bearing liabilities and higher volume of those liabilities, partially offset by the effect of one less accrual day. The average rate paid on interest-bearing liabilities rose 63 bp to 1.36% in 2005. Rates paid on most liabilities moved with general market conditions. The average rate on short-term borrowings rose 159 bp. Rates on deposits increased as well, including those on CDs with balances over $100 thousand, which rose 131 bp, on retail CDs, which went up by 54 bp, and on money market checking accounts, which rose 12 bp. Average interest-bearing liability balances grew $331.9 million or 11.5% for 2005 over 2004, primarily due to the REBC acquisition. Average short-term borrowings increased $161 million. Average long-term debt increased $15.3 million, due to the assumption of REBC’s debt, reduced by an annual principal repayment. Most categories of deposits grew including non-interest bearing demand deposits (up $103.1 million), money market checking (up $55.6 million), passbook savings (up $30.2 million), and CDs over $100 thousand (up $94.5 million).

Provision for Credit Losses
In 2006, the provision for credit losses was $450 thousand, of which $445 thousand was allocated to loan losses and $5 thousand was allocated to unfunded loan commitment losses. The provision was $900 thousand for 2005 and $2.7 million for 2004, all of which were allocated to loan losses. The reductions in the provision reflect Management’s view of credit risk in the loan portfolio and the results of the Company’s continuing efforts to improve loan quality by enforcing relatively conservative underwriting and administration procedures and aggressively pursuing collection efforts. For further information regarding net credit losses and the allowance for credit losses, see the “Credit Quality” section of this report.
Investment Portfolio
The Company maintains a securities portfolio consisting of securities issued by U.S. Government sponsored entities, state and political subdivisions, and asset-backed and other securities. Investment securities are held in safekeeping by an independent custodian.
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. The held to maturity investment portfolio had a duration of 3.9 years at December 31, 2006 and, on the same date, those investments included $1,124.2 million in fixed-rate and $40.9 million in adjustable-rate securities.
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. Unrealized net gains and losses on these securities are recorded as an adjustment to equity, net of taxes, but are not reflected in the current earnings of the Company. If a security is sold, any gain or loss is recorded as a credit or charge to earnings and the equity adjustment is reversed. At December 31, 2006, the Company held $615.5 million in securities classified as investments available for sale with a duration of 2.9 years. At December 31, 2006, an unrealized gain of $2.2 million, net of taxes of $1.3 million, related to these securities, was included in shareholders’ equity.
The Company had no trading securities at December 31, 2006, 2005 and 2004.
For more information on investment securities, see Notes 1 and 3 to the consolidated financial statements.

Commitments and Letters of Credit
It is not the policy of the Company to issue formal commitments on lines of credit except to a limited number of 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 and lines of credit typically mature within one year. For further information, see Note 14 to the consolidated financial statements.
Credit Quality
The Company closely monitors the markets in which it conducts its lending operations and continues its strategy to control exposure to loans with higher credit risk and to increase diversification of the loan portfolio. Credit reviews are performed using grading standards and criteria similar to those employed by bank regulatory agencies. Loans receiving lesser grades fall under the “classified loans” category, which includes all nonperforming and potential problem loans, and receive an elevated level of Management attention to ensure collection.
Classified Loans and Other Real Estate Owned
The following summarizes the Company’s classified loans for the periods indicated: Classified Loans and OREO

Other real estate owned

Total
  $ 20,827     $ 29,997  
 
Classified loans at December 31, 2006, decreased $9.8 million or 32.7% from a year ago primarily due to 13 loan payoffs totaling $17.4 million, three loan upgrades totaling $4.4 million and a transfer to other real estate owned (“OREO”), partially offset by 16 loan downgrades totaling $15.0 million.

Table of Contents

OREO at December 31, 2006 was $647 thousand compared with none a year ago because collateral for one commercial real estate loan was foreclosed in the second quarter of 2006.
Nonperforming Loans
Nonperforming loans include nonaccrual loans and loans 90 or more days past due and still accruing. Loans are placed on nonaccrual status upon becoming delinquent 90 days or more, unless the loan is well secured and in the process of collection. 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 even though the borrowers continue to repay the loans as scheduled. Such loans are classified by Management as “performing nonaccrual” and are included in total nonaccrual loans. 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. Nonaccrual loans are reinstated to accrual status when improvements in credit quality eliminate the doubt as to the full collectibility of both interest and principal.
The following table summarizes the nonperforming assets of the Company for the periods indicated:

Performing nonaccrual loans at December 31, 2006 were $148 thousand or 3.5% higher than the previous year, primarily as a result of new loans being placed on nonaccrual, partially offset by charge-offs, loans being returned to accrual status and loans being placed on nonperforming nonaccrual. Except five relationships totaling $338 thousand, performing nonaccrual loans at December 31, 2005 were either paid off, charged off or brought current in 2006. Nonperforming nonaccrual loans at December 31, 2006 declined $2 million due to the net result of loans being returned to accrual status or being charged off or paid off, a transfer to OREO and others being added to nonperforming nonaccrual. The $647 thousand real estate owned at December 31, 2006 consisted of one property.
Performing nonaccrual loans at December 31, 2005 were $184 thousand higher than the previous year, as a result of the $4.0 million performing nonaccrual loans acquired from REBC and new loans being placed on nonaccrual status, less charge-offs, loans being returned to accrual status and loans being placed on nonperforming nonaccrual status. Except one relationship totaling $666 thousand, performing nonaccrual loans at December 31, 2004 were either paid off, charged off or brought current in 2005. Nonperforming nonaccrual loans at December 31, 2005 declined $902 thousand compared with a year earlier, attributable to loans being returned to accrual status, transfers to repossessed collateral or being charged off or paid off, partially offset by loans being added to nonperforming nonaccrual status. With the exception of three relationships totaling $1.4 million, all loans on nonperforming nonaccrual status at December 31, 2004 were either paid off, charged off or brought current in 2005. There was no other real estate owned (“OREO”) at December 31, 2005 since one property foreclosed during 2005 was disposed of at a small gain.
The Company had no restructured loans as of December 31, 2006, 2005 and 2004.
The amount of gross interest income that would have been recorded if all nonaccrual loans had been current in accordance with their original terms while outstanding during the period was $502 thousand in 2006, $556 thousand in 2005 and $462 thousand in 2004. The amount of interest income that was recognized on nonaccrual loans from cash payments made in 2006, 2005 and 2004 was $488 thousand, $353 thousand and $439 thousand, respectively. Cash payments received, which were applied against the book balance of performing and nonperforming nonaccrual loans outstanding at December 31, 2006, totaled approximately $50 thousand, compared with $452 thousand and $135 thousand at December 31, 2005 and 2004, respectively.

Management believes the overall credit quality of the loan portfolio continues to be strong; however, total nonperforming assets could fluctuate in the future. The performance of any individual loan can be impacted by external factors such as the economy and interest rate environment, or factors particular to the borrower. The Company expects to maintain nonperforming loans and OREO at their current levels; however, no assurance can be given that increases in nonaccrual loans will not occur in future periods.
Allowance for Credit Losses
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 loans and classified loans, recommendations of regulatory authorities, prevailing economic conditions and other factors. A portion of the allowance is specifically allocated to impaired loans whose full collectibility 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 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 reserve 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. Last, allocations are made to non-criticized and classified commercial loans and residential real estate loans based on commercial office vacancy rates, mortgage loan foreclosure trends, agriculture commodity prices, and levels of government funding. The remainder of the reserve is considered to be unallocated and is established at a level considered necessary based on relevant economic conditions and available data, including unemployment statistics, economic and business conditions, the quality of lending management and staff, credit quality trends, concentrations of credit, and changing underwriting standards due to competitive factors. Management considers the $59.0 million allowance for credit losses to be adequate as a reserve against losses as of December 31, 2006.
During 2003, Management refined its allowance methodology for commercial real estate loans, agricultural loans and certain municipal loans. This refinement had the effect of increasing the allowance allocation for commercial loans with a corresponding decrease in the unallocated allowance as of December 31, 2003.

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 $250 thousand.
Nonaccrual commercial and construction loans with outstanding principal balances less than $250 thousand, and large groups of smaller-balance homogeneous loans such as installment, personal revolving credit, residential real estate and student loans, are evaluated collectively for impairment under the Company’s standard loan loss reserve methodology.
The following summarizes the Company’s recorded investment in impaired loans for the dates indicated:
Impaired Loans
                 
At December 31,

Total impaired loans
  $ 493     $ 117  
 
 
               
Specific reserves
  $ 493     $ 117  
 
The average balance of the Company’s impaired loans for the year ended December 31, 2006 was $234 thousand compared with $29 thousand and $731 thousand in 2005 and 2004, respectively. All impaired loans are on nonaccrual status. However, interest income may be recorded as cash is received, provided that the Company’s recorded investment in such loans is deemed collectible. Total interest income recognized for impaired loans in 2006, 2005 and 2004 under the cash basis was not significant.

Asset and Liability Management
The fundamental objective of the Company’s management of assets and liabilities is to maximize its economic value while maintaining adequate liquidity and a conservative level of interest rate risk.
Interest rate risk is the most 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 remaining cash flow of various assets or liabilities may shorten or lengthen as interest rates change. In addition, interest rates may have an indirect impact on loan demand, credit losses, deposit flows and other sources of earnings such as account analysis fees on commercial deposit accounts, official check fees and correspondent bank service charges.
In adjusting the Company’s asset/liability position, Management attempts to manage interest rate risk while enhancing 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.
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, assuming an increase of 100 bp in the federal funds rate and an increase of 72 bp in the 10 year Constant Maturity Treasury Bond yield during the same period, estimated earnings at risk would be approximately 3.9% of the Company’s most likely net income plan for 2007. Conversely, assuming a decrease of 100 bp in the federal funds rate and a decrease of 36 bp in the 10 year Constant Maturity Treasury Bond yield during the same period, earnings are estimated to improve 1.1% over the Company’s most likely net income plan for 2007. 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.
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.
Other types of market risk, such as foreign currency exchange risk, equity price risk and commodity price risk, are not significant in the normal course of the Company’s business activities.
During 2005 as the Company reviewed its interest rate risk position to include the acquisition of REBC, in Management’s judgment, the Company’s interest rate risk exposure would be reduced through the sale of investment securities available for sale, with the proceeds from sale applied to reduce short-term borrowed funds. As a result, the Company sold $170.0 million of investment securities available for sale with a duration of 3.2 years and book yield of 3.29% at a realized loss of $4.9 million.
Liquidity
The Company’s principal source of asset liquidity is investment securities available for sale and principal payments from consumer loans. At December 31, 2006, investment securities available for sale totaled $616 million. At December 31, 2006, indirect auto loans totaled $424 million, which were experiencing stable monthly principal payments of approximately $18 million. In addition, at December 31, 2006, the Company had customary lines for overnight borrowings from other financial institutions in excess of $700 million and a $35 million line of credit, under which $20.5 million was outstanding at December 31, 2006. As a member of the Federal Reserve System, the Company also has the ability to borrow from the Federal Reserve. The Company’s short-term debt rating from Fitch Ratings is F1 with a stable outlook. Management expects the Company can access short-term debt financing if desired. The Company’s long-term debt rating from Fitch Ratings is A with a stable outlook. Management expects the Company can access additional long-term debt financing if desired.
The Company generates significant liquidity from its operating activities. The Company’s profitability during 2006, 2005 and 2004 resulted in operating cash flows of $108.0 million, $117.8 million and $111.3 million, respectively. In 2006, operating activities provided a substantial portion of cash for $40.7 million in shareholder dividends and $89.0 million of share repurchase activity. In 2005, operating activities provided a substantial portion of cash for $39.3 million in shareholder dividends and $95.4 million used to purchase and retire company stock. The operating cash flows in 2004 were more than sufficient to pay $35.1 million in shareholder dividends and retire $55.4 million of the Company’s common stock.

The Company’s investing activities were also a net source of cash in 2006. Proceeds from maturing investment securities of $250.2 million were only partially reinvested, for a net increase in cash of $219.4 million. Other investing activities included net loan repayments of $139.3 million. These cash inflows substantially offset a $329.4 million decrease in customers’ deposits and a $43.2 million reduction in short-term borrowings. Throughout 2006, competition for deposits was elevated in the banking industry due to rising short-term interest rates and funding demands.
During 2005, the Company financed its acquisition of REBC by issuing approximately 1.6 million shares of common stock and approximately $57 million in cash to REBC shareholders. The cash consideration was accumulated in the second half of 2004 and early 2005 as the Company reduced its share repurchase activity. The acquisition of REBC increased the loan portfolio by approximately $440 million, deposits by approximately $370 million, and subordinated debt by approximately $20 million. Other investing activities included sale and maturity of investment securities, net of purchases, of approximately $215.1 million. The Company also experienced net loan repayments of $66.9 million. The proceeds from liquidating investment securities were applied to reduce short-term borrowings by $47.6 million. The Company also experienced a $107.5 million decrease in deposit balances as interest-sensitive CDs and money market products declined while short-term interest rates rose throughout 2005.
In 2004, purchases, net of sales and maturities, of investment securities were $270.7 million, which was generally financed by a $119.6 million increase in deposits and a $144.8 million increase in short-term borrowings.
The Company anticipates maintaining its cash levels in 2007 mainly through profitability and retained earnings. It is anticipated that loan demand will be moderate during 2007, although such demand will be dictated by economic and competitive conditions. A highly competitive environment for deposits has developed as short-term interest rates have steadily increased. The Company aggressively solicits non-interest bearing demand deposits and money market checking deposits, which are the least sensitive to interest rates. However, higher costing products, including money market savings and certificates of deposit, have been less stable during the recent period of rising short-term interest rates. The growth of deposit balances is subject to heightened competition and the success of the Company’s sales efforts and delivery of superior customer service. Depending on economic conditions, interest rate levels, and a variety of other conditions, deposit growth may be used to fund loans, purchase investment securities or to reduce short-term borrowings. However, due to concerns regarding uncertainty in the general economic environment, competition, possible terrorist attacks and political uncertainty, loan demand and levels of customer deposits are not certain. Shareholder dividends and share repurchases are expected to continue subject to the Board’s discretion and continuing evaluation of capital levels, earnings, asset quality and other factors.
The Parent Company’s primary source of liquidity is dividends from Westamerica Bank (the “Bank”). Dividends from the Bank are subject to certain regulatory limitations. During 2006, 2005 and 2004, the Bank declared dividends to the Company of $108, $122 and $95 million, respectively.
The following table sets forth the known contractual obligations of the Company at December 31, 2006:

The Company repurchases its Common Stock in the open market with the intention of supporting shareholder returns and mitigating the dilutive impact of issuing new shares for employee stock award and option plans. Pursuant to these programs, the Company repurchased 1.8 million shares in 2006, 1.8 million shares in 2005 and 1.1 million shares in 2004.
The Company’s primary capital resource is shareholders’ equity, which decreased $10.8 million or 2.5% in 2006 from the previous year, primarily the net result of $40.7 million in dividends paid and $89.0 million in stock repurchases, offset by $98.8 million in profits earned during the year, $12.9 million in issuance of stock in connection with exercises of employee stock options.
The Company’s ratio of equity to total assets rose to 8.90% at December 31, 2006 from 8.44% a year ago because total assets decreased relatively more than shareholders’ equity. Capital to Risk-Adjusted Assets
The risk-based capital ratios rose at December 31, 2006 from December 31, 2005 due to a decrease in risk-weighted assets. The following table summarizes the Company’s capital ratios for the dates indicated:

Deposit competition increased during 2006 due to rising short-term interest rates. The Company modified its deposit pricing practices to retain its profitable customers. However, total average deposits declined by $200.6 million or 5.2% from 2005 due to an outflow of $55.4 million of noninterest bearing deposits, a $14.9 million decrease in interest bearing demand deposits, a $149.0 million decrease in savings deposits and a $41.4 million decrease in CDs less than $100 thousand, partially offset by a $60.1 million increase in CDs over $100 thousand.
During 2005, total average deposits increased by $283.4 million or 7.9% from 2004 primarily due to the REBC acquisition. Average deposit categories increased $103 million for noninterest bearing deposits, plus a $76 million increase in interest bearing demand and savings deposits. Also, time deposits in excess of $100 thousand increased by $94 million.

Noninterest income for 2006 was $807 thousand or 1.5% higher than in 2005. In 2005 the Company incurred $4.9 million in losses on sales of securities to manage the Company’s interest rate risk position following the REBC acquisition. The losses were partially offset by a $3.7 million gain on sale of real estate. Merchant credit card fees increased $763 thousand or 8.4% primarily due to a higher transaction volume and a full year of fees earned from the credit card processing unit of the REBC after the acquisition on March 1, 2005. A $282 thousand or 8.8% increase in debit card fees was attributable to higher usage. Official check sales income increased $281 thousand or 25.3% due to the higher earnings credit rate on outstanding items. ATM fees and interchange increased $113 thousand or 4.2% mainly due to price increases effective as of February 2006 for withdrawals at non-Westamerica Bank ATMs. Service charges on deposit accounts declined $692 thousand or 2.4% largely due to a decrease in deficit fees charged on analyzed accounts (down $828 thousand or 12.5%) as a result of the higher earnings credit rate, lower returned item charges (down $287 thousand or 11.6%) and DDA activity charges (down $223 thousand or 3.8%), partially offset by an increase in overdraft fees (up $616 thousand or 4.5%). Mortgage banking income decreased $113 thousand or 38.7% mainly due to lower activity. Other noninterest income declined $1.2 million or 16.0% mostly because the 2005 period included $945 thousand in company owned life insurance proceeds.
Noninterest income for 2005 was $16.0 million or 41.4% higher than 2004 mainly because 2005 included a $5.6 million increase in merchant credit card income primarily due to the REBC acquisition, a $3.7 million gain on sale of real estate and $945 thousand in life insurance proceeds, partially reduced by $4.9 million in realized securities losses. Furthermore, 2004 noninterest income was reduced by $7.2 million in securities impairment writedowns and a $2.2 million loss on extinguishment of debt, which was offset by $2.2 million in realized investment securities gains. Debit card fees increased $666 thousand or 26.2% primarily due to increased usage. Service charges on deposit accounts increased $485 thousand or 1.7% primarily due to an increase in overdraft fees, an increase in the number of accounts and product repricing in February of 2005. A decrease in account analysis income, due to a higher earnings credit rate, partially offset the overdraft fee increase. Official check sales fees increased mostly due to a higher earnings credit rate on outstanding balances. A $224 thousand or 9.0% increase in ATM fees and interchange income was mostly attributable to product repricing in February of 2005. Trust fees were higher by $154 thousand or 15.0% mainly due to more customers, product repricing and increases in court approved fees. Financial services commissions also increased $137 thousand or 11.0% mainly due to higher sales of variable annuities, partially offset by lower sales of fixed annuities. Other noninterest income increased $2.5 million due, in part, to $945 thousand in life insurance proceeds.

In 2006, noninterest expense decreased $5.5 million or 5.2% compared with 2005. Salaries and related benefits declined $3.6 million or 6.4%, primarily the net result of a $1.9 million decrease in regular salary expenses. The decrease in regular salaries was attributable to the net effect of a smaller workforce and annual merit increases to continuing staff. Telephone expense declined $481 thousand or 22.7% primarily due to lower rates contained in a new vendor contract. Equipment expense declined $263 thousand or 5.0% mainly due to lower repair and maintenance costs. Courier service cost was lower by $204 thousand or 5.3% than in 2005. Advertising and public relations decreased $122 thousand or 12.6% largely due to lower advertising and marketing research expenses. Stationery and supplies decreased $101 thousand or 8.0%. Other noninterest expense decreased $1.7 million or 18.9% largely due to reclassification of credit card expense, lower insurance costs and a decrease in correspondent bank charges, offset by a $223 thousand increase in amortization of low-income housing investments as tax benefits are realized. Occupancy expense was higher by $468 thousand or 3.7% primarily due to a $650 thousand increase in rent, net of sublease income, partially offset by lower depreciation expenses. A $462 thousand increase in amortization of identifiable intangibles was attributable to the March 1, 2005 REBC acquisition.
Noninterest expense increased $5.2 million or 5.0% in 2005 compared with 2004 largely due to an increase in amortization of deposit intangibles from the REBC acquisition. Occupancy increased $644 thousand or 5.4% largely due to a $342 thousand increase in rent, net of sublease income, increases in repair and maintenance and moving expense and higher utility costs. Professional fees increased $551 thousand or 29.5% due to an increase in audit and accounting costs primarily due to additional charges from the company’s independent auditor in connection with new audit requirements promulgated by the Public Company Accounting Oversight Board and higher legal fees for the REBC acquisition. A $418 thousand or 8.7% increase in equipment expense was mainly a $220 thousand increase in depreciation and a $146 thousand increase in equipment repair and maintenance expense. Courier service costs increased $226 thousand or 6.3%. Postage increased $208 thousand or 14.8%. Other noninterest expense increased $259 thousand or 3.1% largely due to a $305 thousand increase in amortization of limited partnership investments as tax benefits are realized, and higher internet banking expense, partially offset by reduced insurance costs. Loan expenses declined $132 thousand or 12.3% mainly due to a decrease in repossession related expenses.

Provision for Income Tax
In 2006, the Company recorded income tax expense (FTE) of $59.1 million, $5.1 million or 8.0% lower than the previous year, primarily due to lower earnings. The effective tax rate of 37.4% (FTE) for 2006 is slightly lower than the 37.7% (FTE) for 2005. The nominal tax rate declined from 27.1% for 2005 to 26.5% for 2006. Tax provision in 2006 reflected tax credits and other benefits realized from additional investments in low income housing projects, tax refunds and other tax items. Tax provision in 2005 reflected tax refunds in connection with the acceptance of amended returns and the tax-exempt nature of $945 thousand in life insurance proceeds.
The income tax provision (FTE) increased by $5.7 million or 9.7% in 2005 compared to 2004, primarily as a result of higher earnings and $2.0 million higher FTE adjustment for increased earnings on tax-advantaged investments and loans. The 2005 provision (FTE) of $64.2 million
reflects an effective tax rate of 37.7% compared to a provision of $58.5 million in 2004, representing an effective tax rate of 38.6%. The nominal tax rate declined from 27.7% for 2004 to 27.1% for 2005. Tax provision in 2005 reflected tax refunds in connection with the acceptance of amended returns and the tax-exempt nature of $945 thousand in life insurance proceeds.
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.
Interest rate risk as discussed above is the most significant market risk affecting the Company, as described in the preceding sections regarding “Asset and Liability Management” and “Liquidity.” Other types of market risk, such as foreign currency exchange risk, equity price risk and commodity price risk, are not significant in the normal course of the Company’s business activities.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Management of Westamerica Bancorporation and Subsidiaries (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal control over financial reporting as of December 31, 2006. 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, 2006 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, 2006 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.
Dated February 26, 2007

Report of Independent Registered Public Accounting Firm
The Board of Directors and Shareholders
Westamerica Bancorporation:
We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial Reporting, that Westamerica Bancorporation and Subsidiaries (the Company) maintained effective internal control over financial reporting as of December 31, 2006, 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. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of 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, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and 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, management’s assessment that the Company maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Westamerica Bancorporation and Subsidiaries as of December 31, 2006 and 2005, 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, 2006, and our report dated February 26, 2007 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.
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. These estimates and judgments may affect reported amounts of assets and liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. The most significant of these involve the Allowance for Credit Losses, as discussed below under “Allowance for Credit Losses.”
Principles of Consolidation. The consolidated financial statements include the accounts of the Company and all the Company’s subsidiaries. Significant intercompany transactions have been eliminated in consolidation. The Company does not maintain or conduct transactions with any unconsolidated special purpose entities other than low income housing partnerships sponsored by third parties.
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 purchase, 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 and municipalities, corporations, mortgage-backed securities, and equity securities. The Company classifies its debt and marketable equity securities in one of three categories: trading, available for sale or held to maturity. Securities transactions are recorded on a trade date basis. 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 amortized 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 until realized.
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 interest rates, there has not been significant deterioration in the financial condition of the issuer, and the Company has the intent and ability to hold the security for a sufficient time to recover the carrying value. An unrealized loss in the value of an equity security is generally considered temporary when the fair value of the security is below the carrying value primarily due to current market conditions and not deterioration in the financial condition of the issuer, and the Company has the intent and ability to hold the security for a sufficient time to recover the carrying value. 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.

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 collectibility 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.
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 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.
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 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 and other factors. A portion of the allowance is specifically allocated to impaired and other identified loans whose full collectibility 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 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. Last, allocations are made to non-criticized and classified commercial loans and residential real estate loans based on commercial office vacancy rates, mortgage loan foreclosure trends, agriculture commodity prices, and levels of government funding. The remainder of the reserve is considered to be unallocated and is established at a level considered necessary based on relevant economic conditions and available data, including unemployment statistics, economic and business conditions, the quality of lending management and staff, credit quality trends, concentrations of credit, and changing underwriting standards due to competitive factors.
Other Real Estate Owned. Other real estate owned is comprised of property acquired through foreclosure proceedings, acceptances of deeds-in-lieu of foreclosure and some 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 balance 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.
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 over their respective estimated useful lives to their estimated residual values. 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 annually evaluated for impairment.
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. For financial reporting purposes, the income tax effects of transactions are recognized in the year in which they enter into the determination of recorded income, regardless of when they are recognized for income tax purposes. Accordingly, the provisions for income taxes in the consolidated statements of income include charges or credits for deferred income taxes relating to temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. Deferred tax assets and liabilities are reflected at currently enacted income tax rates in the period in which the deferred tax assets or liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes.
Derivative Instruments and Hedging Activities. The Company’s accounting for derivative instruments, including certain derivative instruments embedded in other contracts, requires the Company to recognize those items as assets or liabilities in the statement of financial position and measure them at fair value.
Stock Options. Effective January 1, 2006, the Company adopted FASB Statement No.123(revised 2004), Share-Based Payment (SFAS No. 123(R)) on a modified retrospective basis. SFAS No. 123(R) requires the Company to begin using the fair value method to account for stock based awards granted to employees in exchange for their services. Prior to the adoption of SFAS No. 123(R), the Company accounted for stock option plans using the intrinsic value method, as permitted by SFAS No. 123, “Accounting for Stock-Based Compensation.” Under the prior intrinsic value method, compensation expense was recorded for stock options only if the price of the underlying stock on the date of grant exceeded the exercise price of the option. The Company’s historical stock option grants were awarded with exercise prices equal to the prevailing price of the underlying stock on the dates of grant; therefore, no compensation expense was recorded using the intrinsic value method. The Company’s recognition of compensation expense for restricted performance share grants has not changed with the adoption of SFAS No. 123(R). The Company has recognized compensation expense for historical 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, at which time the issued shares become classified as shareholders’ equity.
Earnings Per Share. Basic earnings per share are computed by dividing net income by the average number of shares outstanding during the year. Diluted earnings per share are computed by dividing net income by the average number of shares outstanding during the year plus the impact of dilutive common stock equivalents.
Calculation of basic and diluted net income per share follow:

For the years ended December 31, 2006, 2005, and 2004, options to purchase 719 thousand, 294 thousand and 135 thousand shares of common stock, respectively, were outstanding but not included in the computation of diluted net income per share because the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect.
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. The Company offers a continuation of group insurance coverage to eligible employees electing early retirement until age 65. The Company pays a portion of these early retirees’ insurance premium which are determined at their date of retirement. The Company reimburses a portion of Medicare Part B premiums for all retirees and spouses over 65. The Company does not fund its post-retirement benefit plan.
Other. Securities and other property held by the Bank in a fiduciary or agency capacity are not included in the financial statements since such items are not assets of the Company or its subsidiaries.
Recently Issued Accounting Pronouncements
In February 2006, the FASB issued FAS 155, Accounting for Certain Hybrid Financial Instruments, which amends FAS 133, Accounting for Derivatives and Hedging Activities, and FAS 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities. Hybrid financial instruments are single financial instruments that contain an embedded derivative. Under FAS 155, entities can elect to record certain hybrid financial instruments at fair value as individual financial instruments. Prior to this amendment, certain hybrid financial instruments were required to be separated into two instruments — a derivative and host — and generally only the derivative was recorded at fair value. FAS 155 also requires that beneficial interests in securitized assets be evaluated for either freestanding or embedded derivatives. FAS 155 is effective for all financial instruments acquired or issued after January 1, 2007. FAS 155 will have no effect on our consolidated financial statements on the date of adoption.
In July 2006, the Financial Accounting Standards Board issued Financial Interpretation No. 48, “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 supplements FAS 109, “Accounting for Income Taxes,” by defining the threshold for recognizing tax benefits in the financial statements as “more likely than not” to be sustained by the applicable taxing authority. The benefit recognized for a tax position that meets the “more likely than not” criterion is measured based on the largest benefit that is more than 50% likely to be realized, taking into consideration the amounts and probabilities of the outcomes upon settlement. The Company will adopt FIN 48 effective January 1, 2007, as required. The cumulative effect of applying the new requirements must be reflected as adjustments to the Company’s retained earnings as of January 1, 2007. At December 31, 2006, the Company’s reserve for uncertain tax positions was less than $1 million; any adjustment to retained earnings will be immaterial.
In September 2006, the SEC staff issued Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements” (SAB 108). SAB 108 was issued in order to eliminate the diversity of practice surrounding how public companies quantify financial statement misstatements. The Company has historically focused on the impact of misstatements on the income statement, including the reversing effect of prior year misstatements. With a focus on the income statement, the Company’s analysis can lead to the accumulation of misstatements in the balance sheet. In applying SAB 108, the Company must also consider accumulated misstatements in the balance sheet. SAB 108 permits companies to initially apply its provisions by recording the cumulative effect of misstatements as adjustments to the balance sheet as of the first day of the fiscal year, with an offsetting adjustment recorded to retained earnings, net of tax. The Company has adopted SAB 108 with an adjustment to reduce other liabilities by $3 million, with a corresponding increase to retained earnings of $1.8 million, net of tax. The $3 million overstatement of other liabilities accumulated over seventeen years, as the liability accrued for stock-based compensation exceeded the amount paid to employees. These misstatements had not previously been material to the income statements for any of those prior periods.

In September 2006, the Financial Accounting Standards Board issued FASB Statement No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“FAS 158”). FAS 158 requires recognition of the funded status of the Company’s benefit plans as a net liability or asset, which requires an offsetting adjustment to accumulated other comprehensive income in shareholders’ equity. The Company adopted these recognition and disclosure provisions of FAS 158 effective December 31, 2006, which required recognition of the previously unrecognized transition obligation for the Company’s postretirement medical benefit program. The following table illustrates the adjustments recorded to adopt FAS 158:

Total stockholders’ equity
    424,629       (394 )     424,235  
FAS 158 requires the Company to measure its benefit obligations as of the balance sheet date effective December 31, 2008. The Company currently uses a September 30 measurement date.
In September 2006, the FASB issued FAS 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (GAAP), and expands disclosures about fair value measurements. FAS 157 applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. FAS 157 is effective for the year beginning January 1, 2008, with early adoption permitted on January 1, 2007. The Company does not expect that the adoption of FAS 157 will have a material effect on its consolidated financial statements.
In February 2007, the FASB issued FASB Statement No. 159, The Fair Value Option for Financial Assets and Financial Liabilities — Including an Amendment of FASB Statement No. 115 (“FAS 159”). This standard permits entities to choose to measure many financial assets and liabilities and certain other items at fair value. An enterprise will report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date. The fair value option may be applied on an instrument-by-instrument basis, with several exceptions, such as those investments accounted for by the equity method, and once elected, the option is irrevocable unless a new election date occurs. The fair value option can be applied only to entire instruments and not to portions thereof. FAS 159 is effective as of the beginning of an entity’s first fiscal year beginning after November 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity makes that choice in the first 120 days of that fiscal year and also elects to apply the provisions of FASB Statement No. 157, Fair Value Measurements. Management is currently evaluating the effects of adopting FAS No. 159 on its consolidated financial statements.
Note 2: Business Combinations
In a business combination, the results of operations of the acquired entity are included in the consolidated financial statements from the date of acquisition. Assets and liabilities of the entity acquired are recorded at fair value on the date of acquisition and goodwill is recorded as the excess of the purchase price over the fair value of the net assets acquired (including identifiable intangible assets such as core deposits). See “Intangible Assets” below.
Acquisition of Redwood Empire Bancorp
The Company acquired Redwood Empire Bancorp, parent company of National Bank of the Redwoods, on March 1, 2005, in order to increase the Company’s market share in Northern California. The cash and stock acquisition was accounted for under the purchase method of accounting. The transaction was valued at approximately $150 million.

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, 2006 and 2005, the Company had no high-risk collateralized mortgage obligations as defined by regulatory guidelines.

Substantially all of the securities set forth in the two preceding tables are investment-grade debt securities which have experienced a decline in fair value due to changes in market interest rates, not in estimated cash flows. Since the Company has the intent and ability to retain its investment in these securities for a period of time to allow for any anticipated recovery in market value, no other than temporary impairment was recorded on these securities during 2005 and 2006.
In the fourth quarter of 2004, the Company recognized a $7.2 million securities impairment writedown to market value of certain issues of Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”) preferred stock held in the available for sale investment portfolio. The writedown was recorded as a reduction to noninterest income. The after-tax effect was $4.2 million, net of tax benefits of $3.0 million. At December 31, 2005, the Company held FNMA and FHLMC preferred stock with a cost basis of $63.9 million and a tax-equivalent dividend yield of 7.65%. At December 31, 2006, the Company held FNMA and FHLMC preferred stock with a cost basis of $63.9 million and a tax-equivalent dividend yield of 8.82%.
As of December 31, 2006, $937.9 million of investment securities were pledged to secure public deposits and short-term funding needs, compared to $842.3 million in 2005. The Bank is a member of the Federal Reserve Bank (“FRB”) and held Federal Reserve Bank stock stated at cost of $11.3 million at December 31, 2006 and $11.3 million at December 31, 2005.

Note 9: Shareholders’ Equity
The Company grants stock options and restricted performance shares (RPSs) 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 became 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.
Effective January 1, 2006, the Company adopted FASB Statement No.123(revised 2004), Share-Based Payment (SFAS No. 123(R)) on a modified retrospective basis. SFAS No. 123(R) requires the Company to begin using the fair value method to account for stock based awards granted to employees in exchange for their services. Prior to the adoption of SFAS No. 123(R), the Company accounted for stock option plans using the intrinsic value method, as permitted by SFAS No. 123, “Accounting for Stock-Based Compensation.” Under the prior intrinsic value method, compensation expense was recorded for stock options only if the price of the underlying stock on the date of grant exceeded the exercise price of the option. The Company’s historical stock option grants were awarded with exercise prices equal to the prevailing price of the underlying stock on the dates of grant; therefore, no compensation expense was recorded using the intrinsic value method. The Company’s recognition of compensation expense for restricted performance share grants has not changed with the adoption of SFAS No. 123(R). The Company has recognized compensation expense for historical 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, at which time the issued shares become classified as shareholders’ equity.
The scope of SFAS 123(R) includes a wide range of stock-based compensation arrangements including stock options, restricted stock plans, performance-based awards, stock appreciation rights, and employee stock purchase plans. SFAS 123(R) requires that the Company measure the cost of employee services received in exchange for an award of equity instruments based on the fair value of the award on the grant date. That cost must be recognized in the income statement over the vesting period of the award. In applying the “modified retrospective” method to implement SFAS No. 123 (R), the Company adjusted the financial statements for prior periods to give effect to the fair-value-based method of accounting for awards that were granted, modified or settled in the fiscal years beginning after December 15, 1994 on a basis consistent with the pro forma disclosures required by Statement 123. Accordingly, compensation costs and the related tax effects are recognized in those financial statements as though awards for those periods before the effective date of Statement 123(R) had been accounted for under Statement 123. In addition, the opening balances of common stock, deferred taxes and retained earnings for the earliest year presented are adjusted to reflect the cumulative effect of the modified retrospective application on earlier periods.
The following table summarizes information about stock options granted under the Plans as of December 31, 2006. The intrinsic value is calculated as the difference between the market value as of December 31, 2006 and the exercise price of the shares. The market value as of December 31, 2006 was $50.63 per share as reported by the NASDAQ Global Select Market:

The Company applies the Roll-Geske option pricing model (Modified Roll) to determine grant date fair value of stock option grants. This model modifies the Black — Scholes Model to take into account dividends and American options. During the twelve months ended December 31, 2006, 2005 and 2004, the Company granted 258 thousand, 560 thousand, and 540 thousand stock options, respectively. The following weighted average assumptions were used in the option pricing to value stock options granted in the periods indicated:

*2   the expected life is the number of years that the Company estimates that the options will be outstanding prior to exercise
 
*3   the risk-free rate for periods within the contractual term of the option is based on the US Treasury yield curve in effect at the time of the grant
Employee stock option grants are being expensed by the Company over the grants’ three year vesting period. The Company issues new shares upon the exercise of options. The number of shares authorized to be issued for options is 2.2 million.
The impact of adopting SFAS 123(R) is summarized in the following table (in thousands, except per share data):

The weighted average estimated grant date fair value, as defined by SFAS 123(R), for options granted under the Company’s stock option plan during the twelve months ended December 31, 2006, 2005 and 2004 was $6.54, $6.61 and $6.93 per share, respectively. The total remaining unrecognized compensation cost related to nonvested awards as of December 31, 2006 is $3.3 million and the weighted average period over which the cost is expected to be recognized is 1.7 years.
The total intrinsic value of options exercised during the twelve months ended December 31, 2006, 2005 and 2004 was $7.8 million, $9.8 million and $8.6 million, respectively. The total fair value of RPSs that vested during the twelve months ended December 31, 2006, 2005 and 2004 was $1.0 million, $1.1 million and $789 thousand, respectively. The total fair value of options vested during the twelve months ended December 31, 2006, 2005 and 2004 was $3.6 million, $4.1 million, and $4.5 million, respectively.

As of December 31, 2006 and 2005, the restricted performance shares had a weighted-average contractual life of 1.2 years. The compensation cost that was charged against income for the Company’s restricted performance shares granted was $606 thousand and $525 thousand for the twelve month ended December 31, 2006 and 2005, respectively. There were no stock appreciation rights or incentive stock options granted in the twelve months ended December 31, 2006 and 2005. The Company repurchases and retires its common stock in accordance with Board of Directors approved share repurchase programs. At December 31, 2006, 1.4 million shares remained available to repurchase under such plans.
Shareholders have authorized two additional classes of stock of one million shares each, to be denominated “Class B Common Stock” and “Preferred Stock,” respectively, in addition to the 150 million shares of common stock presently authorized. At December 31, 2006, no shares of Class B Common Stock or Preferred Stock had been issued.
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, which have been amended and restated in 1989, 1992, 1995, 1999 and 2004, are exercisable only in the event of an acquisition of, or announcement of a tender offer to acquire, 10 percent or more of the Company’s stock without the prior consent of the Board of Directors. If the Rights become exercisable, the holder may purchase one share of the Company’s common stock for $110.00, subject to adjustment. In the event a person or a group has acquired, or obtained the right to acquire, beneficial ownership of securities having 10 percent or more of the voting power of all outstanding voting power of the Company, proper provision shall be made so that each holder of a Right will, for a 60-day period thereafter, have the right to receive upon exercise that number of shares of common stock having a market value of two times the exercise price of the Right, to the extent available, and then a common stock equivalent having a market value of two times the exercise price of the Right. Under certain circumstances, the Rights may be redeemed by the Company at $.001 per Right prior to becoming exercisable and in certain circumstances thereafter. The Rights will expire on the earliest of (i) December 31, 2009, (ii) consummation of a merger transaction meeting certain characteristics or (iii) redemption of the Rights by the Company.

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 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 and other deductions including the unrealized net gains and losses, after taxes, of 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 issued by the Company 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, 2006, 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 table shows capital ratios for the Company and the Bank:

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. 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 as of December 31 are as follows:
                 
    2006     2005*  
 
    (In thousands)

*   Adjusted to adopt Financial Accounting Standard 123 (revised 2004), “Share-Based Payment.” See Note 9.
Based on Management’s judgment, a valuation allowance is not needed to reduce the gross deferred tax asset because it is more likely than not that the gross deferred tax asset will be realized through recoverable taxes or future taxable income. Net deferred tax assets are included with
Interest Receivable and Other Assets in the Consolidated Balance Sheets.
The provision for federal and state income taxes consists of amounts currently payable and amounts
deferred which, for the years ended December 31, are as follows:

Note 12: Fair Value of Financial Instruments
The fair values presented represent the Company’s best estimate of fair value using the methodologies discussed below. The fair values of financial instruments which have a relatively short period of time between their origination and their expected realization were valued using historical cost. 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. Such financial instruments and their estimated fair values at December 31 were:

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 maximum 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 $55.3 million in 2006 and $55.8 million in 2005 were applied against the estimated fair values to recognize estimated future defaults of contractual cash flows. The book values and the estimated fair values of loans at December 31 were:

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
Twenty-seven banking offices and a centralized administrative service center are owned and sixty-nine facilities are leased. Substantially all the leases contain multiple renewal options and provisions for rental increases, principally for cost of living index, property taxes and maintenance. The Company also leases certain pieces of equipment.
Minimum future rental payments, net of sublease income, at December 31, 2006, are as follows:

Total rentals for premises and equipment, net of sublease income, included in noninterest expense were $5.8 million in 2006, $5.1 million in 2005 and $4.8 million in 2004.
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 $490.8 million and $491.1 million at December 31, 2006 and 2005, 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 $20.1 million and $30.1 million at December 31, 2006 and 2005, respectively.
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.
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. Eligible employees become vested in account balances subject to a five-year cliff vesting schedule. Company contributions charged to noninterest expense were $1.1 million in 2006 and $1.6 million in 2005 and 2004.
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 common stock. The Company makes matching contributions to employee accounts which vest immediately; such contributions charged to compensation expense were $1.3 million in 2006 and $1.5 million in 2005 and 2004.

The Company offers a continuation of group insurance coverage to qualifying 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 uses a September 30 measurement date for determining post-retirement benefit calculations.
The following tables set forth the net periodic post-retirement benefit cost for the years ended December 31 and the funded status of the post-retirement benefit plan and the change in the benefit obligation as of December 31:

The above discount rate is based on the Corporate Aa 25-year 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 6.50 percent for 2007 and beyond.
Assumed benefit inflation rates have a significant effect on the amounts reported for health care plans. A one percentage point change in the assumed benefit inflation rate would have the following effect on 2006 results:

Note 16: Related Party Transactions
Certain directors and executive officers of the Company and/or its subsidiaries were loan customers of the Bank during 2006 and 2005. All such loans were made in the ordinary course of business on normal credit terms, including interest rate and collateral requirements. In the opinion of Management, these credit transactions did not involve, at the time they were contracted, more than the normal risk of collectibility or present other unfavorable features. The table below reflects information concerning loans to certain directors and executive officers and/or family members during 2006 and 2005:

Note 17: Regulatory Matters
Payment of dividends to the Company by the Bank is limited under regulations for Federal Reserve member 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 that year plus the net profits of the preceding two calendar years less dividends paid. Under this regulation, Westamerica Bank sought and obtained approval during 2006 to pay to the Company dividends of $108.1 million in excess of net profits as defined. The Company consistently has paid quarterly dividends to its shareholders since its formation in 1972. As of December 31, 2006, $186.4 million 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 $19.2 million in 2006 and $17.5 million in 2005.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors
Westamerica Bancorporation:
We have audited the accompanying consolidated balance sheets of Westamerica Bancorporation and Subsidiaries (the Company) as of December 31, 2006 and 2005, 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, 2006. 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, 2006 and 2005, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles.
As discussed in Note 9 to the consolidated financial statements, the Company adopted FASB Statement No.123(revised 2004), Share Based Payment, in 2006. Also, as discussed in Note 1 to the consolidated financial statements, the Company changed its method of quantifying errors in 2006.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006, 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 26, 2007 expressed an unqualified opinion on management’s assessment of, and the effective operation of, internal control over financial reporting.
