The UK pay-television group will spend as much as 61.5 million pounds on financial and broking advice and up to 20 million pounds on lawyers for their work on the Fox bid, according to a circular published by Sky. Other costs include fees for accountancy and public relations advice.
Fox, which already owns 39 percent of Sky, is battling U.S. cable giant Comcast for control of the broadcaster. Comcast is currently in the lead after Sky's independent directors last month recommended its 14.75 pound a share offer, which trumped Fox's 14 pound a share bid.
