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.
** If DirecTV is unable to strike a deal with the National Football League to renew the satellite TV operator's contract to offer the popular NFL Sunday Ticket football package, AT&T Inc can pull out of the merger, according to a regulatory filing.
AT&T Inc plans to pay $48.5 billion to buy DirecTV, in the latest sign that the wireless industry and the U.S. television market are set to converge as customers consume more video on their mobile devices.
** Yahoo Japan Corp has dropped its plan to buy mobile network operator eAccess Ltd from SoftBank Corp in a 324 billion yen ($3.2 billion) deal that was part of a reorganization of SoftBank group assets.
** South African mobile operator Vodacom Group said it reached an agreement to buy unlisted telecoms firm Neotel in a deal worth 7 billion rand ($676 million) although it would not assume any of the company's debt. Neotel, majority-owned by India's Tata Communications, is South Africa's second-biggest fixed-line phone operator.
** Germany's Siemens is working on a formal asset-swap offer for Alstom's power business that could come as early as this week and see France take a stake in a resulting rail-focused French group, sources close to the talks told Reuters. Alstom is already in talks with U.S. conglomerate General Electric over a 12.35 billion euro ($16.9 billion) bid for its power arm, which it is due to review by June 2. However, under pressure from the French government, it has opened its books to Siemens so it can propose its own deal if it wants to.

The newly formed company will have total value of $7.5 billion in revenue, he said.
** KKR & Co is nearing a deal to buy Singapore's Goodpack Ltd, the world's largest maker of intermediate bulk containers which has a market value of S$1.36 billion ($1.1 billion), sources with direct knowledge of the matter said.
Separately, KKR may team up with a Japanese state-backed fund to find buyout targets for its $6 billion Asian fund, a year after the U.S. private equity firm and some rivals complained that state funds could impinge on their investment opportunities. KKR has been in talks with the Innovation Network Corp of Japan for possible joint investment, Hirofumi Hirano, chief executive of KKR Japan, said at the Reuters Japan Investment Summit.
