Westamerica Bancorporation /s/ JOHN "ROBERT" THORSON ------------------------------------------------- John "Robert" Thorson Senior Vice President and Chief Financial Officer September 5, 2008 Page 4 INDEX TO EXHIBITS ----------------- Sequentially Exhibit No. Description Number Page ----------- ------------------------- ------------- (99.1) Announcement dated 5-6 September 5, 2008 Page 5 Exhibit 99.1: ------------- As of June 30, 2008, Westamerica Bancorporation owned preferred stock in Federal Home Loan Mortgage Corporation ("FHLMC") and Federal National Mortgage Association ("FNMA") with a carrying value of $44.5 million. Due to market and economic conditions, the value of these securities has been highly volatile, declining approximately $20.4 million to approximately $24.1 million as of August 31, 2008. Management continues to evaluate all of its options related to these securities. Management believes a 46 percent decline in value of preferred stock is a strong indication of "other than temporary impairment." Management has fully evaluated the capital condition of both Westamerica Bancorporation and its banking subsidiary, Westamerica Bank, and concluded both will remain above the highest regulatory capital level of "well capitalized" under any valuation scenario involving the FHLMC and FNMA preferred stock holdings. In evaluating capital levels, Management has included the following expectations regarding third quarter 2008 earnings, excluding any charges for "other than temporary impairment:" * Diluted earnings per share of approximately $0.78 * A fully-taxable equivalent net interest margin in excess of 5.20 percent, compared to 5.16 percent in the second quarter 2008 * A lower base of earning assets compared to the second quarter 2008 primarily due to a smaller investment portfolio. * A provision for loan losses of $600 thousand. Management expects loan quality to remain stable relative to the second quarter 2008. Westamerica's allowance for loan losses represented 2.10 percent of loans at June 30, 2008. Diluted earnings per share of $0.78 represents a return on shareholders equity in excess of 20 percent. Due to this relatively high level of operating earnings, the Company has flexibility in managing its capital levels. As announced on August 28, 2008, the Board of Directors renewed the Company's share repurchase plan, authorizing the repurchase of up to two million shares prior to September 1, 2009. The Board of Directors raised the Company's quarterly dividend to $0.35 per share on April 24, 2008. During the third quarter 2008, the Company intends to retire $10 million in trust preferred debt which qualifies as regulatory capital. The Company has determined it does not need the trust preferred debt to support its "well capitalized" regulatory capital level. Retirement of this high-cost debt supports Westamerica's low cost of funds, which is expected to decline in the third quarter 2008 from 0.87 percent reported for the second quarter 2008.
