Glencore offers $41B for full stake in XstrataGlencore International, the world's largest commodities trading company, said it has offered to pay about $41 billion for the 66 percent stake in the mining company Xstrata that it did not already own, in a long-anticipated deal that would create a mining giant with a market value of nearly $90 billion. By merging with Xstrata, Glencore would enhance its position in emerging markets like Africa, Kazakhstan and South America. The company, to be renamed Glencore Xstrata International, would be the fourth-largest diversified mining company in the world, with revenue of $209 billion and pretax profit of $16 billion, based on 2011 figures. On Tuesday, major investors in Xstrata balked at the acquisition, looking for Glencore to sweeten the offer.
