(Reuters) - Twenty-First Century Fox Inc FOXA.O on Tuesday posted an offer document and form of acceptance for its 14 pounds a share offer to buy UK's Sky SKYB.L on Tuesday.

Fox now intends to implement Sky’s acquisition by way of a takeover offer rather than a scheme of arrangement, as described in the Companies Act 2006, with the deal conditional on 75 percent or more Sky shareholders accepting the offer.

The deadline to set out a revised offer document is Sept. 22, Fox added.

Fox's current offer still lags Comcast Corp's CMCSA.O 14.75 pounds a share bid, leaving the world's biggest entertainment group in the lead of the long-winded takeover battle for the British pay-TV group.

In a separate announcement, Sky acknowledged Fox’s offer document and said its independent committee would respond to the offer within 14 days.
