On March 22, 2012, we acquired a 75% ownership interest in PSI Energy Solutions, LLC ("PSI") for cash consideration of $7,000,000. PSI is a professional services firm that develops cost-effective energy solutions for public and private entities throughout North America. We anticipate completing the purchase price allocation for this acquisition in the fourth quarter of fiscal 2012. The acquired net assets became part of our Global Group operating segment upon closing and will be reported in the "Other" category for segment reporting purposes.
