The San Diego-based company had originally planned the offering for earlier this year but postponed it due to problems with its contract with Greece for security for the 2004 Olympics.

Last week employee shareholders voted in favor of the flotation on the New York Stock Exchange in a ballot which was delayed from early September. The company plans to sell 75 million shares to the public at a price range of $13 to $15 per share, and could begin trading next week.

SAIC is currently owned by its 43,000 employees, for which the company is arranging a special dividend, worth a total of up to $1.4bn. Employees will continue to control the company as the shares being offered in the IPO have far less voting rights than the current shares.
