Deals of the day- Mergers and acquisitions
(Adds Telefonica, Publicis, Actis, Murphy Oil, Google; Updates DirecTV, Twitch)
May 19 (Reuters) - The following bids, mergers, acquisitions and disposals were reported by 2000 GMT on Monday:
** Britain's AstraZeneca rejected a sweetened and "final" offer of about 70 billion pounds ($118 billion) from Pfizer, casting serious doubt on the U.S. drugmaker's plan for a merger to create the world's biggest pharmaceuticals group.
AstraZeneca's chairman said he saw no prospect of a deal with Pfizer before a deadline of May 26 set under UK takeover rules, or any likelihood of that deadline being extended.
Pfizer is likely to court major investors in AstraZeneca as part of a takeover attempt despite a board rejection of its bid, the head of Britain's parliamentary science committee said.
** Activist investor William Ackman said in a letter to takeover target Allergan Inc's board of directors that the top executive has a "disabling" conflict of interest because accepting a takeover means losing the top job. Ackman and Valeant Pharmaceuticals International launched a $47 billion takeover of Allergan on April 22, but so far Allergan has rejected its advances and Chief Executive Officer David Pyott is pushing shareholders to let the company stand alone.
