Dec 12 (Reuters) - The following bids, mergers, acquisitions and disposals were reported by 2100 GMT on Wednesday:
** Rosneft has finalised a deal to buy half of TNK-BP for $28 billion, clearing the way for a full takeover that would make the state-controlled Russian oil major the world's largest listed oil firm by output.
** Warburg Pincus LLC has mandated Goldman Sachs Group Inc to explore a sale of eye care company Bausch & Lomb Inc, hoping to fetch more than $10 billion, a person familiar with the matter said on Tuesday.
** Malaysia's Petronas completed its C$5.2 billion ($5.3 billion) takeover of Progress Energy Resources Corp on Wednesday, a deal that was expected to have sailed through Canada's approval process but got ensnared in a heated national debate about foreign control of energy assets.
