NEW YORK (Bloomberg) — Bermuda-based Genpact Ltd., a computer services company spun off by General Electric Co. in 2004, boosted the amount it plans to raise in an initial public offering to as much as $731 million.The company expects to sell 17.6 million shares for $16 to $18 each, according to a registration statement filed yesterday. Shareholders GE, General Atlantic Partners LLC and Oak Hill Capital Partners LP plan to sell another 17.6 million shares in the same range, while the underwriters have an option to buy 5.29 million shares, Genpact said. In a May 11 filing, Genpact said it expected to raise $600 million.

Genpact, which began in 1997 as an India-based unit that assisted GE's finance division, will use the proceeds to repay debt and for general corporate purposes, including potential acquisitions.

GE sold 60 percent of the unit, formerly known as GE Capital International Services, for $500 million to buyout firms General Atlantic and Oak Hill in 2004. Fairfield, Connecticut-based GE, the world's second-biggest company by market value, owns about a third of Genpact and accounted for almost three quarters of the company's $613 million in 2006 sales.

Genpact plans to trade on the New York Stock Exchange under the symbol "G," the ticker of Gillette Co. until the consumer- goods company was bought by Procter & Gamble Co. in 2005.

The IPO is being managed by Morgan Stanley, Citigroup Inc. and JPMorgan Chase & Co. The shares will go on sale "as soon as practicable," Genpact said in yesterday's filing.

Shares of GE rose 38 cents to $39.88 at 10.39 a.m. in New York Stock Exchange composite trading. They rose 6.2 percent this year before yesterday.
