As previously announced, CDW completed the acquisition of Berbee Information Networks Corporation on October 11, 2006. February 2006 sales do not include Berbee sales, while February 2007 sales include Berbee sales. Excluding Berbee sales in February 2007, and therefore on a non-GAAP basis, CDWs average daily sales for February 2007 were $26.080 million compared to average daily sales for February 2006 of $24.533 million and total sales for February 2007 were $521.6 million compared to total sales of $490.7 million for February 2006, both representing an increase of 6.3 percent.

In February 2007 average daily sales for the public sector segment increased 16.8 percent and average daily sales for the corporate sector segment increased 2.5 percent compared to the prior year period. While CDW did not own Berbee prior to October 11, 2006, the Company is providing comparative information for Berbee. Compared to the prior year periods, average daily sales for Berbee increased 26.2 percent in January 2007 and 61.8 percent in February 2007. Compared to the public sector and corporate sector segments, Berbee’s business model is more project oriented, which can result in a greater degree of variability in sales on a monthly basis.
