FILE - In this Feb. 7, 2012 file picture the Xstrata logo, is pictured at the headquarters of Xstrata in Zug, Switzerland. Commodities trader Glencore International said Wednesday, June 27, 2012 that it is considering changes in incentives for senior employees of Xstrata, amid growing shareholder concerns over its proposed takeover of the mining company. The possible revision of the offer comes barely two weeks ahead of a shareholders vote on the deal. Glencore's announcement followed a demand by a Qatari investment fund for better terms for its 10 percent stake in Xstrata. It wants 3.25 new Glencore shares for each Xstrata share, significantly more than the 2.8 shares currently on offer. (AP Photo/Keystone/Sigi Tischler,File) less
