Citi trader pact not in pay czar's purview-source

NEW YORK, Aug 12 (Reuters) - Citigroup Inc's (C.N) contract with energy trader Andrew Hall, which reportedly could pay him up to $100 million this year, will not be subject to rulings by the Obama administration's pay czar, a source close to the bank said on Wednesday.

Pay czar Kenneth Feinberg on Friday is expected to begin reviewing compensation structures at several companies that received bailouts, including Citi, which has taken $45 billion from the U.S. Treasury's Troubled Asset Relief Program, known as TARP.

While Feinberg has authority over the top 100 employees' pay -- and Hall surely ranks among those -- the source said Hall's contract will be exempt from review by the pay czar because it was signed before a cut-off date of Feb. 11, 2009.

Treasury officials, who did not comment on Hall specifically, have said Feinberg will have "broad authority" to ensure appropriate compensation, although he cannot force companies to break contractual obligations not covered by rules that govern pay restrictions.
