Forbes Magazine Honors PACCAR Executive PACCAR Celebrates Its Centennial in 2005

BELLEVUE, Wash.--May 3, 2005-- Forbes magazine (www.forbes.com) recently published its annual CEO pay-versus-performance review. In the pay-versus-performance rankings, Forbes evaluated 189 CEOs who met the qualification criteria of a minimum of six-year tenure as chief executive. The rankings were calculated by company stock performance (including dividends) versus peer companies and relative to the S&P 500 Index. The final criterion was the executive's compensation trends during the previous years.

The scores were combined and one of the following grades was assigned based on the executive's and company's performance: A+, A, B, C, D, F. The top ten best-performing CEOs were graded as A+ in the review.
