As always, our performance directly reflects the strength of our customer relationships and our commitment to helping build vital, strong communities. These loyal customers and our outstanding team of employees were the driving force behind a successful year. They are the foundation for our focus on earnings growth, increasing market share in every area we serve, and expanding our geographic footprint as we position ourselves as a Pacific Northwest regional community bank dedicated to meeting the diverse financial needs of all the communities we serve. Net income grew 32% to $29.6 million during 2005, up from $22.5 million during 2004. For the same periods diluted earnings per share grew 23% to $1.87, from $1.52. Return on average equity increased 52 basis points to 13.81% and return on average tangible equity grew 261 basis points to 16.63%. An important driver of our performance was the improvement in our net interest margin, which was 4.44% for the year, up from 4.19% in the prior year. Total revenue growth was very strong, growing 23% to $115.7 million from $94.2 million during 2004. Our loan growth, while moderating during the third quarter, continued to be an important highlight for the year, with loan production increasing throughout our market areas. Total loans ended the year at $1.56 billion, an increase of $205.0 million, or 15%, from one year ago. In addition to healthy loan growth, credit quality substantially improved during 2005, with nonperforming assets dropping 47% to $4.9 million, or 0.31% of total loans, compared to $9.1 million, or 0.62% of total loans, at the end of 2004. At December 31, 2005, nonperforming assets to year-end assets was 0.21% and our allowance for loan and lease losses to nonperforming loans was 429%. We have been very pleased with the positive response from the successful integration of Bank of Astoria, which was accretive to 2005 earnings as planned, and also serves as a base for potential expansion in Oregon. Led by Cheri Folk, President and Chief Executive Officer, the Bank of Astoria continues to be a high performing organization, with a 34% market share in Clatsop County. We are continuing to fill in our geographic footprint as planned. During the second quarter, we opened a branch in University Place, adjacent to Tacoma, which has been well received by the community. In August, we opened a long-awaited branch in the downtown area of Puyallup. With the opening of this additional full-service branch in Puyallup, we closed our small office in the South Hill Mall at the end of November. We currently have a total of 40 branches in the Columbia system—Columbia Bank has 35 branches in five counties, and Bank of Astoria totals five branches in two counties. In many ways, our website constitutes an additional branch location—it is certainly a wonderful channel for a wide range of banking services used by many of our customers. The response to our redesigned website, www.columbiabank.com, has been excellent. The site brings to mind the friendly, full-service feeling that customers enjoy at all of our community branches. It has been twelve full years since we moved Columbia's headquarters to downtown Tacoma and began our rapid expansion. We have certainly grown in both size and profitability. What hasn't changed is who we are. We have stayed true to our conviction that our real strength lies in providing exceptional service to our customers, and investing in our people and the communities we serve. It bears repeating that our goal is to be thecommunity bank in all the communities we serve. In closing, we wish to express our appreciation to all of the employees of Columbia Bank and Bank of Astoria. As always, they are our most important strength—an outstanding team committed to making a difference for our customers and our communities. We know that this commitment translates directly into value for you, our shareholders. Sincerely, WILLIAM T. WEYERHAEUSER MELANIE J. DRESSEL
