WASHINGTON: Web search company Google Inc. on Friday disclosed more details of its stock buyback offer, saying that the 23.2 million shares it may have illegally issued to previous and current employees and consultants have a weighted average price of $2.86 per share.

The company said in an amended offering document filed with the US Securities and Exchange Commission that it expects little acceptance of the buyback offer because of the relatively low price in comparison to the expected initial public offering share price of $108 to $135 per share.

Google's highly anticipated IPO could raise as much as $3.3 billion from its offering of 24.6 million shares.

It revealed in a filing on Wednesday it had sold 23.2 million shares to 1,105 current and former employees and consultants. It granted an additional 5.6 million stock options to 301 people.

The transactions, which took place between September 2001 and June 2004, were not registered as required by law, according to the filing.

Google said the buyback offer, which could cost the company $25.9 million, will start when the planned IPO is completed.

When the buyback offer expires, on an undisclosed date in September, any person who did not accept the offer will have freely tradable stock, subject to the company's lock-up and vesting restrictions, according to the filing.
