Fast 500 Selection and Qualifications

The Fast 500 list is compiled from Deloitte's 15 regional North American Fast 50 lists, nominations submitted directly to the Fast 500, and public company database research. To qualify for the Fast 500, entrants must have had 2000 operating revenues of at least $50,000 USD or $75,000 CD for the United States and Canada, respectively, and 2004 operating revenues of at least $1 million USD or CD.

Entrants must be headquartered in North America and must be a "technology company," defined as a company that owns proprietary technology that contributes to a significant portion of the company's operating revenues; or devotes a significant proportion of revenues to the research and development of technology.
