Company Confidential Pg 5 Publishing: Renewals **Black & Veatch renewed today (Nov 9), it will appear in next week’s report.

Company Confidential Pg 6 Publishing: Individual Renewals Cumulative average renewal trend takes monthly data points and accumulates/averages them over time. For example, Aug 05 is a stand-alone data point for that month. Sep 05 takes Aug and Sep potential renewal and actual renewal and re-computes a 2 month average. Oct 05 takes Aug, Sep, and Oct renewal and re-computes a 3 month average. The rest of the trend months are similarly derived where any given month is a re-computed average of the data for that month and all preceding months. The month percentages are not the key in this metric, but rather the slope of the line. A positive slope (seen here) indicates real improvement over time by removing the potentially skewing impact of individual monthly timing differences (decline recoveries).
