Other revenues consist of state and local government as well as commercial contracts performed by the U.S. Federal sector reporting segment.

Note:

The table above presents revenues for each year by reportable segment as will be disclosed in the Form 10-K. In past years, revenues by market sector were presented, which differs slightly due to the classification of certain overlapping activities between segments. For simplicity, this secondary presentation has been eliminated. The total classification difference between the two presentations was $1.5 million and $3.1 million for the quarter and twelve months ended April 1, 2005, respectively.

*As a result of guidance issued by the SEC in its March 4, 2005 "Current Accounting and Disclosure Issues" the Company reclassified certain securities held on April 2, 2004 from cash to available-for-sale investments. This reclassification increased cash used in investing activities for the 12 months ended April 2, 2004, and decreased such cash by a like amount for the 12 months ended April 1, 2005. The Company believes it is appropriate to exclude such cash flows from its measurement of free cash flows.
