The repurchase plan represents approximately 6.3% of the Company's currently outstanding common stock. This plan replaces the existing two million-share stock repurchase program authorized in August 2003. As previously announced, Westamerica and Redwood Empire Bancorp signed a definitive agreement under which Westamerica will acquire Redwood Empire Bancorp for approximately $148 million in a combination of stock and cash. Westamerica intends to reduce the allocation of its operating cash flow toward the repurchase of its common shares in order to meet the approximate $57 million cash payment for this transaction, which is estimated to be completed in the fourth quarter 2004 or early first quarter 2005. Chairman, President, and CEO David Payne stated "This stock repurchase program is being adopted to continue to provide management with the flexibility to optimize the Company's use of equity capital and enhance shareholder value. Westamerica's strong capital position, profitability and low-risk balance sheet supported the initiation of this new program." Westamerica Bancorporation is the holding company for Westamerica Bank operating 87 branches and 2 trust offices throughout 22 counties in Northern and Central California. At June 30, 2004, total assets were $4.6 billion, Shareholders' equity was $330 million, and total common shares outstanding were approximately 31.8 million.
