Further Review Opportunity From Methodology Design

In addition to facilitating company rankings, Total Score and results shown in the tables for the four performance categories can also be interpreted as percentiles of performance for fiscal 2012 compared with peer results over the 12-year test period. A score of 85, for example, indicates a company's performance is within 14 points of the best result earned by a company in its peer group during the 1998-2009 period.
