Subsequent Event. In the fourth quarter of fiscal 2008, we acquired three consulting and engineering firms: (1) Institute for Public-Private Partnerships, Inc., which advises government and private sector clients including USAID, on public-private partnership structures for infrastructure development; (2) Rothberg, Tamburini & Winsor, Inc., which provides water and wastewater design services to municipalities, mining companies, utilities and industrial clients, and (3) Highlander Environmental Corp., which offers environmental capabilities for oil and gas industry clients. These acquisitions enhance our service offerings and expand our geographic reach. The total initial purchase price for these acquisitions was $19.4 million in cash. In addition, the sellers have certain earn-out rights that allow them to receive additional cash payments over a two or four-year period upon the achievement of certain financial objectives.
