See Note 4. Page 7 NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS Note 1: Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. The results of operations reflect interim adjustments, all of which are of a normal recurring nature and which, in the opinion of Management, are necessary for a fair presentation of the results for the interim periods presented. The interim results for the three months ended March 31, 2006 and 2005 are not necessarily indicative of the results expected for the full year. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes as well as other information included in the Company's Annual Report on Form 10-K for the year ended December 31, 2005. Note 2: Significant Accounting Policies. 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 Loan Losses, which is discussed in Note 1 to the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2005. 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 for the REBC acquisition, 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. On March 17, 2006, the Financial Accounting Standards Board (FASB) issued FASB Statement of Financial Accounting Standards No. 156 (SFAS 156), "Accounting for Servicing of Financial Assets an amendment of FASB No. 140". This Statement amends FASB Statement No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities" (SFAS 140). The new Standard addresses the recognition and measurement of separately recognized servicing assets and liabilities and provides an approach to simplify efforts to obtain hedge-like (offset) accounting. The standard requires that a separately recognized servicing asset or servicing liability be initially measured at fair value, if practicable, and permits an entity with a separately recognized servicing asset or servicing liability to choose either the amortization method or the fair value method for subsequent measurement. The Company currently has approximately $100 thousand in mortgage servicing rights which are currently amortized over the period of estimated mortgage income. This method is consistent with the SFAS 140 requirements. The Company does not currently hedge its mortgage servicing rights as the risks to earnings from fluctuating values is not significant. SFAS 156 is effective for fiscal years beginning after September 15, 2006. The Company will be adopting this new Standard beginning January 1, 2007. Note 3: Goodwill and Other Intangible Assets The Company has recorded goodwill and other identifiable intangibles associated with purchase business combinations. Goodwill is not amortized, but is periodically evaluated for impairment. The Company did not recognize impairment during the three months ended March 31, 2006. Identifiable intangibles are amortized to their estimated residual values over their expected useful lives. Such lives and residual values are also periodically reassessed to determine if any amortization period adjustments are indicated. During the first quarter of 2006, no such adjustments were recorded. In connection with the acquisition of Redwood Empire Bancorp ("REBC") in the first quarter of 2005, the Company recorded goodwill and identifiable intangibles of $109 million and $27 million, respectively, in accordance with the purchase method of accounting. The following tables summarize the Company's goodwill and identifiable intangible assets, as of January 1 and March 31 for 2006 and 2005 (dollars in thousands). In the first quarter of 2006 goodwill relating to the REBC acquisition was reduced by $193 related to stock options issued in connection with the acquisition and increased $5 related to accrued expenses. At At January 1, March 31, 2006 Additions Reductions 2006 ---------------------------------------------------- Goodwill $125,879 $5 ($193) $125,691 Accumulated Amortization (3,972) 0 0 (3,972) ---------------------------------------------------- Net $121,907 $5 ($193) $121,719 ==================================================== Core Deposit Intangibles $24,383 $0 $0 $24,383 Accumulated Amortization (6,972) 0 (582) (7,554) Merchant Draft Processing Intangible 10,300 0 0 10,300 Accumulated Amortization (1,541) 0 (458) (1,999) ---------------------------------------------------- Net $26,170 $0 ($1,040) $25,130 ==================================================== Page 8 At At January 1, March 31, 2005 Additions Reductions 2005 ---------------------------------------------------- Goodwill $22,968 $108,507 $0 $131,475 Accumulated Amortization (3,972) 0 0 (3,972) ---------------------------------------------------- Net $18,996 $108,507 $0 $127,503 ==================================================== Core Deposit Intangibles $7,783 $16,600 $0 $24,383 Accumulated Amortization (4,889) 0 (278) (5,167) Merchant Draft Processing Intangible 0 10,300 0 10,300 Accumulated Amortization 0 0 (127) (127) ---------------------------------------------------- Net $2,894 $26,900 ($405) $29,389 ==================================================== At March 31, 2006, the estimated aggregate amortization of core deposit intangibles, in thousands of dollars, for the remainder of 2006 and annually through 2011 is $1,697, $2,153, $2,021, $1,859, $1,636, and $1,386, respectively. The weighted average amortization period for core deposit intangibles is 12.35 years. At March 31, 2006, the estimated aggregate amortization of merchant draft processing intangible, in thousands of dollars, for the remainder of 2006 and annually through 2011 is $1,350, $1,500, $1,200, $962, $774, and $624, respectively. The weighted average amortization period for merchant draft processing intangibles is 11.92 years. Note 4: Stock Options The Company grants stock options and restricted performance shares to employees in exchange for employee services, pursuant to the shareholder-approved 1995 Stock Option Plan, which was amended and restated in 2003. Stock options are granted with an exercise price equal to the fair market value of the related common stock 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 SFAS No. 123(R), "Share-Based Payment" 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 has recognized compensation expense for historical restricted performance share grants over the relevant attribution period. The scope of FAS 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. FAS 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 March 31, 2006. The intrinsic value is calculated as the difference between the market value as of March 31, 2006 and the exercise price of the shares.

Page 12 Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations Westamerica Bancorporation and subsidiaries (the "Company") reported first quarter 2006 net income of $26.1 million or $.81 diluted earnings per share. These results compare to net income of $22.3 million or $.68 diluted earnings per share and $27.1 million or $.83 diluted earnings per share, respectively, for the first and fourth quarters of 2005. First quarter 2005 results include one month of operating results of Redwood Empire Bancorp ("REBC"), parent company of National Bank of the Redwoods, which was acquired on March 1, 2005. First quarter 2005 also included a loss on sale of available-for-sale investment securities totaling $2.8 million, net of tax, or $0.09 per diluted share outstanding. Following is a summary of the components of net income for the periods indicated (dollars in thousands except per share data): Three months ended --------------------------------------- March 31, December 31, -------------------------- 2006 2005* 2005* --------------------------------------- Net interest income (FTE) $53,974 $55,019 $55,830 Provision for credit losses (150) (300) (150) Noninterest income: Securities losses 0 (4,903) 0 Deposit service charges and other 13,639 12,098 14,427 Total noninterest income 13,639 7,195 14,427 Noninterest expense (25,483) (25,863) (26,980) Provision for income taxes (FTE) (15,863) (13,741) (16,003) --------------------------------------- Net income $26,117 $22,310 $27,124 ======================================= Average diluted shares 32,276 32,680 32,572 Diluted earnings per share $0.81 $0.68 $0.83 Average total assets $5,054,256 $4,864,633 $5,089,078 Net income (annualized) to average total assets 2.10% 1.86% 2.11% * Adjusted to adopt SFAS 123(R) Net income for the first quarter of 2006 was $3.8 million or 17.1% more than the same quarter of 2005, primarily due to higher noninterest income, partially offset by lower net interest income (FTE) and a higher income tax provision. The decrease in net interest income (FTE) (down $1.0 million or 1.9%) was attributable to higher funding costs and lower loan fee income, partially offset by an increase due to growth of average interest-earning assets and higher yields earned on those assets. The loan loss provision decreased $150 thousand or 50.0% from a year ago, reflecting Management's assessment of credit risk for the loan portfolio. Noninterest income increased $6.4 million or 89.6% as 2005 included $4.9 million in securities losses and merchant credit card income rose due to the REBC acquisition. Noninterest expense decreased $380 thousand or 1.5%. The provision for income taxes (FTE) rose $2.1 million or 15.4% largely due to increased pretax income. Comparing the first three months of 2006 to the prior quarter, net income declined $1.0 million or 3.7%, due to lower net interest income (FTE) and lower noninterest income, offset by decreases in noninterest expense and the provision for income taxes. The lower net interest income (FTE) was caused by higher funding costs, the effect of two less accrual days and lower average earning assets, partially offset by higher yields on those assets. Noninterest income decreased $788 thousand or 5.5% due to seasonal declines in merchant card volumes, fewer processing days for deposit services, and $357 thousand life insurance proceeds in the fourth quarter of 2005. Noninterest expense declined $1.5 million or 5.6% primarily due to lower personnel costs. The income tax provision (FTE) decreased mainly due to lower earnings. Page 13 Net Interest Income Following is a summary of the components of net interest income for the periods indicated (dollars in thousands): Three months ended --------------------------------------- March 31, December 31, -------------------------- 2006 2005 2005 --------------------------------------- Interest and fee income $62,467 $57,303 $62,234 Interest expense (14,512) (8,357) (12,519) FTE adjustment 6,019 6,073 6,115 --------------------------------------- Net interest income (FTE) $53,974 $55,019 $55,830 ======================================= Average earning assets $4,606,178 $4,518,930 $4,639,319 Net interest margin (FTE) 4.73% 4.90% 4.80% Approximately eighty percent of the Company's revenue is derived from net interest income, or the difference between interest income earned on loans and investments and interest expense paid on interest-bearing deposits and borrowings. Net interest income (FTE) during the first quarter of 2006 decreased $1.0 million or 1.9% from the same period in 2005 to $54.0 million, mainly due to rates on interest-bearing liabilities (up 75 basis points ("bp")) moving faster than yields on earning assets (up 37 bp), higher average interest-bearing liabilities (up $73 million), and lower loan fee income (down $168 thousand), partially offset by growth of average earning assets (up $87 million.) Comparing the first quarter of 2006 with the previous quarter, net interest income (FTE) declined $1.9 million or 3.3%, primarily due to higher average interest-bearing liabilities (up $37 million), higher rates on those liabilities (up 26 bp), the effect of two less accrual days and lower average earning assets (down $33 million), partially offset by higher yields on those assets (up 13 bp). Interest and Fee Income Interest and fee income (FTE) for the first quarter of 2006 rose $5.1 million or 8.1% from the same period in 2005. The increase was caused by higher average earning assets (up $87.2 million) and higher yields on those assets (up 37 bp), partially offset by lower loan fee income (down $168 thousand.) The average yield on the Company's earning assets, excluding loan fee income, increased from 5.60% in the first quarter of 2005 to 5.97% in the same period in 2006 (up 37 bp). The composite yield on loans, excluding loan fees, rose 41 bp to 6.52% due to increases in the average yields on commercial loans (up 101 bp), residential real estate loans (up 27 bp), direct consumer loans (up 136 bp), construction loans (up 153 bp) and indirect consumer loans (up 15 bp.) The investment portfolio yield increased 18 bp to 5.23%, caused by increases in the average yield on mortgage backed securities and collateralized mortgage obligations (up 23 bp) and U.S. government sponsored entity obligations (up 23 bp). Partially offsetting these increases were decreases in the average yield on municipal securities (down 13 bp) and corporate and other securities (down 40 bp.) Average earning asset expansion of $87 million for the first quarter of 2006 compared to the same period in 2005 was attributable to growth in the loan portfolio, partially offset by a decrease in the investment portfolio. The Company's acquisition of REBC on March 1, 2005 was the principal cause of the loan portfolio growth. Average commercial real estate loans rose by $113 million. Average residential real estate loans were up $87 million and average balances of construction loans and commercial loans were also up $33 million and $16 million, respectively. A $3 million decline in the average balance of direct consumer loans partially offset these increases. Average investments declined $154 million for the first quarter of 2006 compared to the same period in 2005 primarily due to decreased average balances of U.S. government sponsored entity obligations (down $138 million), mortgage backed securities and collateralized mortgage obligations (down $28 million) and other securities (down $9 million), partially offset by a $22 million increase in average municipal securities. The Company sold approximately $170 million in "available-for-sale" U.S. government sponsored entity obligations in the first quarter of 2005 to manage interest rate risk associated with the REBC acquisition. Comparing the first quarter of 2006 with the previous quarter, interest and fee income (FTE) was up $136 thousand or 0.2%. The increase largely resulted from rising yields on those assets, partially offset by the effect of a lower volume of average earning assets. The average yield on earning assets excluding loan fees for the first three months of 2006 was 5.97% compared with 5.84% in the fourth quarter of 2005. The loan portfolio yield excluding loan fees for the first quarter of 2006 compared with the previous quarter was higher by 20 bp, due to increases in yields on commercial loans (up 31 bp), commercial real estate loans (up 22 bp), residential real estate loans (up 10 bp) and construction loans (up 67 bp.) The investment portfolio yield rose by 1 bp. The increase resulted from higher average yields on U.S. government sponsored entity obligations (up 6 bp) and mortgage backed securities and collateralized mortgage obligations (up 3 bp), partially offset by lower average yields on municipal securities (down 5 bp) and corporate and other securities (down 3 bp.) Average earning assets decreased $33 million or 0.7% for the first quarter of 2006 compared with the previous quarter primarily due to a $32 million decline in the investment portfolio. Decreases in average balances of mortgage backed securities and collateralized mortgage obligations (down $28 million) and municipal securities (down $7 million) were partially offset by a $3 million increase in the average balance of other securities. Page 14 The loan portfolio decreased $1 million due to decreases in average balances of commercial loans (down $15 million) and direct consumer loans (down $5 million), offset by increases in average balances of construction loans (up $7 million), residential real estate loans (up $6 million) and indirect consumer loans (up $4 million.) Interest Expense Interest expense in the first quarter of 2006 increased $6.2 million or 73.7% compared with the same period in 2005. The increase was attributable to higher rates paid on the interest-bearing liabilities and growth in those liabilities. The average rate paid on interest-bearing liabilities increased from 1.08% in the first quarter of 2005 to 1.82% in 2006. Rates paid on most liabilities moved with general market conditions: the average rate on federal funds purchased rose 197 bp and rates on deposits increased as well, including those on certificates of deposit ("CDs") over $100 thousand, which rose 161 bp; on retail CDs, which went up by 48 bp; and on money market checking accounts, which rose an average of 9 bp. Interest-bearing liabilities grew $73 million or 2.3% for the first quarter of 2006 over the same period of 2005. CDs over $100 thousand increased $95 million, primarily due to inflows of public funds. Short term borrowings other than federal funds, primarily repurchase agreements with commercial banking customers, increased $42 million. Long-term debt increased $11 million, the net result of assumption of REBC's $20 million subordinated debentures and scheduled annual repayments of senior notes. Offsetting the increase were decreases in retail CDs (down $17 Million) and money market savings (down $89 million). Comparing the first quarter of 2006 with the previous quarter, interest expense rose $2.0 million or 15.9%, due to higher rates paid on interest-bearing liabilities and growth of such liabilities. Rates paid on liabilities averaged 1.82% during the first three months of 2006 compared with 1.56% in the fourth quarter of 2005. The most significant rate increases were federal funds purchased which rose 46 bp, CDs over $100 thousand which rose 45 bp and retail CDs which increased by 16 bp. Interest-bearing liabilities grew $37 million or 1.2% over the fourth quarter of 2005. Federal funds purchased grew $68 million and CDs over $100 thousand increased $31 million, primarily due to inflows of public funds. An $11 million decline in retail CDs partially offset the increase. In all periods, the Company has attempted to continue to reduce high-rate time deposits while increasing the balances of more profitable, lower-cost transaction accounts in order to minimize the cost of funds. Lower-cost transaction accounts experience seasonal trends primarily due to customer income and property tax payments, with the most significant deposit outflows occurring in the first calendar quarter of each year. Net Interest Margin (FTE) The following summarizes the components of the Company's net interest margin for the periods indicated: Three months ended --------------------------------------- March 31, December 31, -------------------------- 2006 2005 2005 --------------------------------------- Yield on earning assets 6.00% 5.65% 5.87% Rate paid on interest-bearing liabilities 1.82% 1.08% 1.56% --------------------------------------- Net interest spread 4.18% 4.57% 4.31% Impact of all other net noninterest bearing funds 0.55% 0.33% 0.49% --------------------------------------- Net interest margin 4.73% 4.90% 4.80% ======================================= During the first quarter of 2006, the net interest margin declined 17 bp compared with the same period in 2005. Rates paid on interest-bearing liabilities increased faster than the yields on earning assets, resulting in a 39 bp decline in net interest spread. The decline in the net interest spread was mitigated by the higher value of noninterest bearing funding sources. While the average balance of these sources increased $41 million or 3.1%, their value increased 22 bp, from 33 bp in the first quarter of 2005 to 55 bp in the first quarter of 2006, because of the higher earning asset yields at which they could be invested. The net interest margin declined by 7 bp when compared with the fourth quarter of 2005. Earning asset yields increased 13 bp, however, the cost of interest-bearing liabilities rose by 26 bp, resulting in a 13 bp decrease in the interest spread. Although noninterest bearing funding sources decreased $80 million or 5.6%, their margin contribution increased by 6 bp. Page 15 Summary of Average Balances, Yields/Rates and Interest Differential The following tables present, for the periods indicated, information regarding the Company's consolidated average assets, liabilities and shareholders' equity, the amount of interest income from average earning assets and the resulting yields, and the amount of interest expense paid on interest-bearing liabilities. Average loan balances include nonperforming loans. Interest income includes proceeds from loans on nonaccrual status only to the extent cash payments have been received and applied as interest income. Yields on securities and certain loans have been adjusted upward to reflect the effect of income which is exempt from federal income taxation at the current statutory tax rate (FTE) (dollars in thousands).

The Company provided $150 thousand for credit losses in the first quarter of 2005, compared with $150 thousand in the fourth quarter and $300 thousand in the first quarter of 2005. The provision reflects the Company's loss experience and Management's assessment of credit risk in the loan portfolio for each of the periods presented. For further information regarding net credit losses and the allowance for loan losses, see the "Classified Loans" section of this report. Noninterest Income The following table summarizes the components of noninterest income for the periods indicated (dollars in thousands). Three months ended --------------------------------------- March 31, --------------------------December 31, 2006 2005 2005 --------------------------------------- Service charges on deposit accounts $7,083 $6,927 $7,202 Merchant credit card fees 2,385 1,298 2,751 Debit card fees 828 697 865 ATM fees and interchange 678 624 653 Official check issuance income 334 225 310 Financial services commissions 298 279 380 Trust fees 282 273 275 Check sale income 200 289 176 Mortgage banking income 50 100 62 Securities losses 0 (4,903) 0 Other noninterest income 1,501 1,386 1,753 --------------------------------------- Total $13,639 $7,195 $14,427 ======================================= Noninterest income for the first quarter of 2006 rose by $6.4 million or 89.6% from the same period in 2005, which included $4.9 million in securities losses arising from sales of investment securities available for sale. Merchant credit card income increased $1.1 million or 83.7% primarily due to the acquisition of the merchant card servicing business of Redwood Empire Bancorp on March 1, 2005. Service charges on deposit accounts increased $156 thousand or 2.25% mainly due to a $199 thousand increase in overdraft fees, partially offset by declines in retail and business checking account service fees. Debit card fees rose $131 thousand or 18.8% largely due to increased usage. Official check issuance income increased $109 thousand or 48.4% mainly due to higher earning credit rates on outstanding checks. Other noninterest income was higher by $115 thousand or 8.3% mostly due to $108 thousand in interest received on tax refunds. In the first quarter of 2006, noninterest income decreased $788 thousand or 5.5% compared with the previous quarter. Merchant credit card income declined $366 thousand or 13.3% primarily due to seasonally lower credit card sales. Service charges on deposit accounts fell $119 thousand or 1.7% mostly due to a $124 thousand decline in overdraft fees. Other noninterest income declined $252 thousand or 14.4% mainly because the previous quarter included $357 thousand in life insurance proceeds while the first quarter of 2006 included $108 thousand in interest received on tax refunds. Page 21 Noninterest Expense The following table summarizes the components of noninterest expense for the periods indicated (dollars in thousands). Three months ended --------------------------------------- March 31, --------------------------December 31, 2006 2005* 2005* --------------------------------------- Salaries and incentives $13,258 $13,883 $13,867 Occupancy 3,232 2,952 3,196 Data processing services 1,534 1,548 1,524 Equipment 1,266 1,230 1,321 Amortization of identifiable intangibles 1,040 405 1,064 Courier service 922 926 952 Professional fees 457 720 599 Telephone 432 528 497 Postage 410 422 441 Customer checks 290 231 248 Stationery and supplies 270 348 314 Advertising/public relations 234 206 237 Loan expense 195 204 200 Operational losses 189 190 303 Correspondent service charges 183 250 217 Other noninterest expense 1,571 1,820 2,000 --------------------------------------- Total $25,483 $25,863 $26,980 ======================================= Average full time equivalent staff 939 963 945 Noninterest expense to revenues (FTE) 37.69% 41.57% 38.40% * Reflects the adoption of SFAS 123(R) Noninterest expense decreased $380 thousand or 1.5% in the first quarter of 2006 compared with the same period in 2005. The largest decline was salaries and incentives, which was down $625 thousand or 4.5% mainly due to a $211 thousand decrease in stock based compensation (Restricted Performance Shares ("RPS") and stock options), a $186 thousand decrease in regular salaries resulting from reduced full time equivalent employees, a $153 thousand decrease in retirement plan costs, and a $112 thousand decrease in employee incentives, partially offset by annual merit increases to continuing staff. Professional fees were down $263 thousand or 36.5% mainly because the first quarter of 2005 included legal fees associated with the REBC acquisition and higher audit fees. Other noninterest expense declined $249 thousand or 13.7% mainly due to lower cost of insurance. The $635 thousand increase in amortization of identifiable intangibles was attributable to the REBC acquisition. Occupancy expense increased $280 thousand 9.5% primarily due to a $289 thousand increase in rent, net of sublease income, resulting from the REBC acquisition and annual increases. In the first three months of 2006, noninterest expense fell $1.5 million or 5.6% compared with the fourth quarter of 2005. Salaries and incentives declined $609 thousand or 4.4% mainly due to a decrease in incentives and stock based compensation (stock options), offset in part by a seasonal increase in payroll taxes. Other noninterest expense declined $429 thousand or 21.5% due to a $357 thousand gain on company owned life insurance. Professional fees decreased $142 thousand or 23.7% mainly due to decreased legal fees relating to loans. Finally, operational losses declined $114 thousand. Provision for Income Tax During the first quarter of 2006, the Company recorded income tax expense (FTE) of $15.9 million, compared to $13.7 million and $16.0 million for the first and fourth quarters of 2005, respectively. The current quarter provision represents an effective tax rate of 37.8%, compared with 37.4% and 36.4% for the first and fourth quarters of 2005, respectively. The tax provisions and effective tax rates fluctuated due to the relative level of tax- exempt income from municipal investments and loans to the level of pretax income, tax-free life insurance proceeds of $375 thousand in the fourth quarter of 2005, and benefits from the apportionment of income to affiliates for state tax purposes. Classified Loans The Company closely monitors the markets in which it conducts its lending operations and continues its strategy to control exposure to loans with high credit risk and to increase diversification of earning assets. Loan reviews are performed using grading standards and criteria similar to those employed by bank regulatory agencies. Loans receiving lesser grades fall under the "classified" category, which includes all nonperforming and potential problem loans, and receive an elevated level of attention to ensure collection. Other real estate owned is recorded at the lower of cost or market. Page 22 The following is a summary of classified loans and other real estate owned on the dates indicated (dollars in thousands): At March 31, At --------------------------December 31, 2006 2005 2005 --------------------------------------- Classified loans $28,878 $35,258 $29,997 Other real estate owned 0 0 0 --------------------------------------- Classified loans and other real estate owned $28,878 $35,258 $29,997 ======================================= Allowance for loan losses / classified loans 193% 170% 186% Classified loans at March 31, 2006, decreased $6.4 million or 18.1% from a year ago. Classified loans increased $16.1 million at the time of the acquisition of REBC. The subsequent decline resulted from upgrades, charge-offs and payoffs, partially offset by new downgrades. Other real estate owned remained at zero at the end of each period shown above. A $1.1 million or 3.7% decrease in classified loans from December 31, 2005 was generally due to paydowns and improved credit quality. Nonperforming Loans Nonperforming loans include nonaccrual loans and loans 90 days past due as to principal or interest and still accruing. Loans are placed on nonaccrual status when they become 90 days or more delinquent, 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, 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 as "performing nonaccrual" and are included in total nonperforming assets. When the ability to fully collect nonaccrual loan principal is in doubt, cash payments received are applied against the principal balance of the loan until such time as full collection of the remaining recorded balance is expected. Any subsequent interest received is recorded as interest income on a cash basis. The following is a summary of nonperforming loans and OREO on the dates indicated (dollars in thousands): At March 31, At --------------------------December 31, 2006 2005 2005 --------------------------------------- Performing nonaccrual loans $3,232 $6,550 $4,256 Nonperforming, nonaccrual loans 2,993 1,766 2,068 --------------------------------------- Total nonaccrual loans 6,225 8,316 6,324 Loans 90 days past due and still accruing 29 107 162 --------------------------------------- Total nonperforming loans 6,254 8,423 6,486 Other real estate owned 0 0 0 --------------------------------------- Total $6,254 $8,423 $6,486 ======================================= As a percentage of total loans 0.24% 0.31% 0.24% Performing nonaccrual loans at March 31, 2006 decreased $3.3 million or 50.7% as the $4.0 million performing nonaccrual loans acquired from REBC were charged off or paid off. Performing nonaccrual loans at March 31, 2006 decreased $1.0 million or 24.1% mainly due to charge-offs, loans being returned to accrual status and loans being placed on nonperforming nonaccrual, partially offset by new loans being placed on nonaccrual. Nonperforming nonaccrual loans at March 31, 2006 increased $1.2 million or 69.5% and $925 thousand or 44.7% from the previous year and December 31, 2005, respectively. The increase was due to the net result of loans being added to nonaccrual, partially offset by loans returned to accrual status or being charged off or paid off. The Company had no restructured loans as of March 31, 2006 and 2005 and December 31, 2005. The amount of gross interest income that would have been recorded for nonaccrual loans for the three months ended March 31, 2006, if all such loans had been current in accordance with their original terms, was $120 thousand, compared to $124 thousand and $134 thousand, respectively, for the first and fourth quarters of 2005. The amount of interest income that was recognized on nonaccrual loans from all cash payments, including those related to interest owed from prior years, made during the three months ended March 31, 2006, totaled $60 thousand, compared to $165 thousand and $45 thousand, respectively, for the first and fourth quarters of 2005. These cash payments represent annualized yields of 4.15% for first three months of 2006 compared to 10.15% and 2.83%, respectively, for the first and the fourth quarter of 2005. Total cash payments received, including those recorded in prior years, which were applied against the book balance of nonaccrual loans outstanding at March 31, 2006, totaled approximately $32 thousand, compared with $151 thousand and $124 thousand for the first and the fourth quarters of 2005, respectively. Page 23 Management believes the overall credit quality of the loan portfolio continues to be strong; however, nonperforming assets could fluctuate from period to period. The performance of any individual loan can be impacted by external factors such as the interest rate environment, economic conditions or factors particular to the borrower. No assurance can be given that additional increases in nonaccrual loans will not occur in the future. 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 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 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 general loan categories 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, unidentified economic and business conditions, the quality of lending management and staff, credit quality trends, concentrations of credit, and changing underwriting standards due to external competitive factors. Management considers the $59.5 million allowance for credit losses to be adequate as a reserve against losses as of March 31, 2006. The following table summarizes the credit loss provision, net credit losses and allowance for credit losses for the periods indicated (dollars in thousands): Three months ended --------------------------------------- March 31, --------------------------December 31, 2006 2005 2005 --------------------------------------- Balance, beginning of period $59,537 $54,152 $59,674 Credit loss provision 150 300 150 Allowance acquired through merger 0 5,213 0 Loans charged off (1,118) (599) (701) Recoveries of previously charged off loans 887 793 414 --------------------------------------- Net credit recoveries (losses) (231) 194 (287) --------------------------------------- Balance, end of period $59,456 $59,859 $59,537 ======================================= Components: Allowance for loan losses 55,768 59,859 55,849 Reserve for unfunded credit commitments (1) 3,688 -- 3,688 --------------------------------------- Allowance for credit losses $59,456 $59,859 $59,537 ======================================= Allowance for loan losses / loans outstanding 2.11% 2.21% 2.09% (1) Effective December 31, 2005, the Company transferred the portion of the allowance for credit losses related to lending commitments and letters of credit to other liabilities. 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 maturity 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, 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. Page 24 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 200 bp in the federal funds rate and an increase of 156 bp in the 10 year Constant Maturity Treasury Bond yield during the same period, estimated earnings at risk would be approximately 4.7% of the Company's most likely net income plan for 2006. 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. Liquidity The Company's principal sources of asset liquidity are investment securities available for sale and principal payments from investment securities held to maturities and consumer loans. At March 31, 2006, investment securities available for sale totaled $643 million. At March 31, 2006, residential real estate loans and indirect auto loans totaled $923 million. In addition, at March 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 $22.2 million was outstanding at March 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 the first three months of 2006 and 2005 contributed to substantial operating cash flows of $33.5 million and $32.5 million, respectively. In 2006, operating activities provided enough cash for $23.0 million of Company stock repurchases and $10.2 million in shareholder dividends. In 2005, operating activities provided a substantial portion of cash for $9.5 million in shareholder dividends, $3.2 million for repayment of long term debt and $20.4 million utilized to repurchase common stock. In the first three months of 2006, investing activities generated $75.7 million, compared with $168.6 million in the same period of 2005. In 2006, sales and maturities, net of purchases, of investment securities were $44.0 million. In 2005, sales and maturities, net of purchases, of investment securities were $172.0 million, which were used to reduce short-term borrowings by $112.3 million. In the first quarter of 2005, the Company used net cash of $35.2 million for the REBC acquisition, which use had been largely facilitated in 2004 by reducing the allocation of operating cash flow used to repurchase and retire common stock. The Company anticipates maintaining its cash levels in 2006 mainly through profitability and retained earnings. It is anticipated that loan demand will increase moderately in 2006, although such demand will be dictated by economic conditions. The growth of deposit balances is expected to exceed the anticipated growth in loan demand through the end of 2006. Depending on economic conditions, interest rate levels, and a variety of other conditions, excess deposit growth may be used to purchase investment securities or to reduce short-term borrowings. However, due to changes in consumer confidence, possible terrorist attacks, the war in Iraq, and changes in the general economic environment, loan demand and levels of customer deposits are not certain. Shareholder dividends and share repurchases are expected to continue in 2006 but will depend on the Board's ongoing evaluation of the advisability of such actions. Westamerica Bancorporation ("the Parent Company") is a separate entity from Westamerica Bank ("the Bank") and must provide for its own liquidity. In addition to its operating expenses, the Parent Company is responsible for the payment of dividends to its shareholders, and interest and principal on outstanding debt. Substantially all of the Parent Company's revenues are obtained from service fees and dividends received from the Bank. Payment of such dividends to the Parent Company by the Bank is limited under regulations for Federal Reserve member banks and California law. The amount that can be paid in any calendar year, without prior approval from federal and state 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. The Company believes that such restrictions will not have an impact on the Parent Company's ability to meet its ongoing cash obligations. Capital Resources The current and projected capital position of the Company and the impact of capital plans and long-term strategies are reviewed regularly by Management. The Company repurchases shares of its common stock in the open market pursuant to stock repurchase plans approved by the Board with the intention of lessening the dilutive impact of issuing new shares under stock option plans, and other ongoing requirements. In addition, other programs have been implemented to optimize the Company's use of equity capital and enhance shareholder value. Pursuant to these programs, the Company collectively repurchased 429 thousand shares in the first quarter of 2006, 372 thousand shares in the first quarter of 2005, and 500 thousand shares in the fourth quarter of 2005. The Company's capital position represents the level of capital available to support continued operations and expansion. The Company's primary capital resource is shareholders' equity, which was $429.4 million at March 31, 2006. This amount, which is reflective of the effect of the generation of earnings, offset by common stock repurchases, dividends paid to shareholders and unrealized loss on securities available for sale, represents a decrease of $16.6 million or 3.71% from a year ago, and a decrease of $5.7 million or 1.31% from December 31, 2005. The Company's ratio of equity to total assets declined to 8.49% at March 31, 2006, from 8.57% a year ago. The shareholder's equity to total assets increased at March 31, 2006, compared with 8.44% at December 31, 2005. Page 25 The following summarizes the ratios of capital to risk-adjusted assets for the periods indicated: At March 31, At Minimum --------------------------December 31, Regulatory 2006 2005 2005 Requirement ---------------------------------------------------- Tier I Capital 9.41% 8.94% 9.08% 4.00% Total Capital 10.73% 10.28% 10.40% 8.00% Leverage ratio 6.18% 6.32% 6.01% 4.00% The risk-based capital ratios rose at March 31, 2006, compared with the first quarter of 2005, due to a decrease in risk-weighted assets and a decrease in goodwill. The risk-based capital ratios rose at March 31, 2006 from the previous quarter due to a decrease in risk-weighted assets. Capital ratios are reviewed by Management on a regular basis to ensure that capital exceeds the prescribed regulatory minimums and is adequate to meet the Company's anticipated future needs. All ratios as shown in the table above are in excess of the regulatory definition of "well capitalized". Item 3. 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. 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. Item 4. Controls and Procedures The Company's principal executive officer and principal financial officer have evaluated the effectiveness of the Company's "disclosure controls and procedures," as such term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended, as of March 31, 2006. Based upon their evaluation, the principal executive officer and principal financial officer concluded that the Company's disclosure controls and procedures are effective. The evaluation did not identify any change in the Company's internal control over financial reporting that occurred during the quarter ended March 31, 2006 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.
