LONDON (Reuters) - Glencore Xstrata
Less than a month after a shareholder vote ousted all former Xstrata directors, the commodities miner and trader said on Wednesday it had appointed three new directors, including Mack, but also Peter Grauer - another investment banking veteran, now chairman of information provider Bloomberg - and Peter Coates, a veteran of the commodities group.
Mack and Grauer bring Wall Street expertise to the board as independent non-executive directors. Coates, who is charged with the integration of Glencore and Xstrata, will be an executive director.
A former chief executive and chairman who led Morgan Stanley through the financial crisis, Mack left the bank - still one of Glencore's key advisers - in 2011, but has taken on other roles in the financial services industry, including as adviser to private equity group KKR.
Peter Grauer, a veteran of now defunct investment bank Donaldson, Lufkin & Jenrette and CSFB Private Equity, has been Bloomberg chairman for over a decade.
Coates is a 45-year veteran of the resource industry, formerly head of Xstrata's coal business before retiring in 2008. He stepped down as chairman of Australian oil and gas firm Santos
The group said its search for a new chairman continues, as it consults with major investors after the abrupt exit of former Xstrata chairman John Bond last month.
