Kraft Foods posted its offer document to Cadbury Plc shareholders on Friday, triggering a 9.8 billion pound ($16.3 billion) takeover fight for the British chocolate maker.
Kraft's bid is unchanged from its indicated offer worth 300 pence in cash and 0.2589 new Kraft share for each Cadbury share, according to an advertisement in the Wall Street Journal.
Cadbury has so far rejected Kraft's cash and shares bid, first disclosed three months ago, forcing Kraft to turn hostile in early November and go directly to Cadbury shareholders in its aim to create the world's largest confectionery group.
Kraft launched its bid in early September which currently values Cadbury shares at 713 pence or 9.8 billion pounds, but Cadbury shares are currently at 801.50 pence reflecting hopes for a higher bid from Kraft or the emergence of rival bids.
