Dec 26 (Reuters) - The following bids, mergers, acquisitions and disposals were reported by 2100 GMT on Thursday:

** French cement maker Lafarge SA said it would sell its remaining 20 percent stake in its former European and South American gypsum operations to Belgian building materials group Etex for 145 million euros ($198 million) in cash.

** Vale SA, the world's No. 1 iron ore producer, sold a 44.25 percent stake in purified phosphoric acid producer Fosbrasil SA to Israel Chemicals Ltd for $52 million, according to a securities filing.

** Billionaire financier George Soros bought 3 percent of heavily indebted Spanish infrastructure firm FCC from the group's founding family, Spanish media reported.

** Japan's SoftBank Corp is in talks to acquire U.S. wireless carrier T-Mobile US Inc and is discussing funding for a deal with financial institutions, sources close to the matter said on Wednesday.

The deal, media reports have said would be valued at about $20 billion.

** Royal Dutch Shell's 23.1 percent stake in Australian oil and gas group Woodside Petroleum is seen as more likely to be split up and/or sold to institutional shareholders than to go in one piece to a strategic buyer, bankers said.

** BlackBerry Ltd co-founder Mike Lazaridis cut his stake in the company to 4.99 percent from 8 percent, and said that a group, which included Lazaridis, walked away from exploring a bid for the troubled smartphone maker.

** Brazilian tycoon Eike Batista's troubled shipbuilder OSX Brasil SA and oil company Oleo e Gas Participacoes SA have taken another step toward emerging from Latin America's largest-ever bankruptcy with a deal to swap Oleo e Gas debt for stock.

OSX will convert $1.5 billion owed it by Oleo e Gas into a 7 percent stake in the reformulated oil company, formerly known as OGX Petroleo e Gas Participacoes SA, it announced late on Wednesday.
