Diluted earnings per share (EPS) for 2006 were $3.11, compared to $3.22 for the year 2005. Return on shareholders' equity for the year 2006 was 23.4 percent and return on assets was 2.01 percent, compared to 25.7 percent and 2.09 percent, respectively, for the year 2005. For the year 2006, shareholder dividends totaled $1.30 per share, a seven percent increase over $1.22 per share for the prior year. Net income for the fourth quarter 2006 totaled $24.0 million, or EPS of $0.77, compared to net income of $24.2 million and EPS of $0.77 for the third quarter 2006. Fourth quarter 2006 results also compare to EPS of $0.83 for the fourth quarter 2005, which included company owned life insurance proceeds, which increased EPS $0.01. "Fourth quarter 2006 results benefited from strength in merchant card processing and debit card fees, and cost containment," said Chairman, President and CEO David Payne. "During the fourth quarter, we continued to focus our sales efforts on gathering noninterest bearing demand deposits to support our net interest margin. Our cost of funds rose just 0.07 percent in spite of fierce competition for deposits. As a result, our net interest margin was 4.49 percent, well within the top-tier for the banking industry. Our efficiency ratio remains low at 39.0 percent, and our credit quality remained stable. Westamerica generated a 23 percent return on our shareholders' equity for the fourth quarter 2006," continued Payne. Page 6 Net interest income on a fully taxable equivalent basis was $49.0 million in the fourth quarter of 2006 compared to $50.2 million in the prior quarter and $55.8 million in the same quarter a year ago. The fourth quarter 2006 net interest margin on a taxable equivalent basis was 4.49 percent, compared to 4.54 percent for the previous quarter and 4.80 percent for the fourth quarter of 2005. For the full year 2006, net interest income and the net interest margin on a fully taxable equivalent basis were $204.7 million and 4.57 percent, compared to $223.9 million and 4.82 percent, respectively, for 2005. The provision for credit losses was $70 thousand for the fourth quarter of 2006, compared to $75 thousand for the previous quarter and $150 thousand for the year ago quarter. The level of the credit loss provision reflects management's assessment of credit risk for the loan portfolio. Noninterest income in the fourth quarter of 2006 totaled $13.7 million, compared to $13.9 million reported for the previous quarter and $14.4 million reported for the year ago quarter. The decrease from the prior quarter is primarily attributable to lower deposit service charges offset in part by higher merchant card processing fees. The decrease from the year ago quarter is due to lower deposit service charges and life insurance proceeds of $355 thousand recognized in the fourth quarter 2005. For the full year 2006, noninterest income increased to $55.3 million from $54.5 million for 2005. The $800 thousand annual increase is attributable to higher merchant card processing and debit card fees offset in part by lower deposit service charges. Noninterest income for 2005 includes a $4.9 million securities loss, $3.7 million in gains from the sale of real estate, and $945 thousand in company owned life insurance proceeds, which combined to reduce noninterest income by $260 thousand. Noninterest expense for the fourth quarter of 2006 totaled $24.5 million compared to $25.4 million in the prior quarter and $27.0 million in the year ago quarter. The decrease from the prior quarter is primarily attributable to lower personnel, occupancy, and other expenses offset in part by higher operational losses. The decrease from the year ago quarter is primarily attributable to lower personnel and telephone expenses. For the full year 2006, noninterest expense was $101.7 million, down five percent from $107.3 million for 2005. The decrease is primarily attributable to lower personnel, telephone and insurance expenses, offset in part by higher amortization of intangible assets due to the acquisition of Redwood Empire Bancorp on March 1, 2005. Page 7 Shareholders' equity was $424 million at December 31, 2006, and the equity-to- asset ratio was 8.9 percent. At December 31, 2006, there were approximately 1.4 million shares remaining to purchase under the Company's existing share repurchase program. At December 31, 2006, the Company's assets totaled $4.8 billion and loans outstanding totaled $2.5 billion.
