New CEO Alfred T. Mockett was hired by AMS in 2001 to grow the company's sales from $1.1 billion to $3 billion a year, with a goal of becoming a top tier system integrator through growth and acquisitions, with an eventual goal of a "big bang merger of equals." When this strategy proved unsuccessful, Mockett negotiated a sale of the firm. CGI, a Canadian company, was the primary purchaser, paying $858 million for the commercial business and all government business not related to national defense. The defense portion of AMS could not be sold to a foreign-based company so CACI purchased the defense and intelligence practice for $415 million. The sale to CGI and CACI was announced in March 2004. The AMS brand was retained by CGI for a time and the AMS website directed users to the CGI site. CGI's United States headquarters are in Fairfax, Virginia.
