Bermudian Brian Duperreault took home almost $25 million in compensation for the 11 months of last year that he served as chief executive officer of global insurance brokers Marsh & McLennan Cos.

The bulk of that compensation was in the form of stock options and restricted stock, valued at more than $20.7 million on the day they were awarded, a regulatory filing showed.

Mr. Duperreault also received $927,083 in base salary, as well as a performance-related cash bonus of $3 million, plus $88,376 in other compensation, for a total of $24.8 million.

The impressive compensation illustrates how much MMC were willing to pay out to lure Mr. Duperreault — a former chairman and CEO of Ace Ltd. — out of retirement.

The calculations, carried out by The Associated Press, include executive salary, bonus, incentives, perks, above-market returns on deferred compensation and the estimated value of stock options and awards granted during the year. The calculations don't include changes in the present value of pension benefits, and they sometimes differ from the totals companies list in the summary compensation table of proxy statements filed with the Securities and Exchange Commission.

The filing shows that Mr. Duperreault's predecessor Michael Cherkasky, who served as CEO until January 29, took home more than $8.2 million in compensation in 2008.

Mr. Cherkasky, whose departure was announced by the company in December 2007, was awarded $83,333 in base salary for 2008. He also received more than $8.1 million in other compensation, which included a cash severance of $7.15 million.

In February this year, Marsh & McLennan reported a loss of $73 million, or 14 cents per share, compared with a profit of $2.48 billion, or $4.53 per share, in 2007. A previously reported non-cash goodwill impairment charge of $540 million in the company's risk consulting and technology segment contributed to the loss.

Total revenue grew 3.7 percent to $11.59 billion from $11.18 billion a year ago, in a tumultuous year for the financial services sector.
