DETROIT - The new chief financial officer at General Motors Co. will receive a salary of $750,000 next year, but he'll get up to another $5.45 million worth of stock starting in 2012 if GM successfully sells shares to the public, reported The Associated Press.

Chris Liddell's pay package exceeds the limits imposed on companies that have received U.S. government aid, but an exemption was worked out with the government pay czar Kenneth Feinberg, GM said in a government filing Wednesday.

Liddell's compensation package will exceed that at Microsoft Corp. when accounting for his stock awards. His pay package at the software giant was about $2.4 million.

Liddell, 51, will leave his job as Microsoft Corp.'s CFO on Dec. 31 and join GM next year. He is seen as a possible candidate for GM's next CEO.

GM's current CEO Ed Whitacre Jr. is not earning a salary, but he receives a $350,000 annual stipend as a board member. His predecessor Frederick "Fritz" Henderson, who was ousted earlier this month, was receiving a compensation package of nearly $5.5 million, including a cash salary of $950,000, under Feinberg's pay rules.

In addition to a base salary of $750,000, Liddell will receive $3.45 million in company stock over three years starting in 2012. He will receive another stock grant of $2 million that vests in three years and is payable in 25 percent installments for every 25 percent repayment of GM's $6.7 billion in government loans.

Under new pay rules for companies that received substantial government aid set in October, the base pay of General Motors' top executives is capped at $500,000. Much of the compensation for GM officials will be paid in company stock that cannot be redeemed until beginning in 2011 or after GM starts repaying its government loans.
