The New York Times is reporting that if Merrill Lynch & Co. (NYSE: MER) CEO Stanley O'Neal left he would be entitled to $159 million in retirement benefits ($30 million) and stock and option holdings ($129 million). This does not include any severance payment the board might award him. Add that to the $160 million Merrill paid him since he took over almost five years ago and you get a $319 million investment in its CEO by Merrill's shareholders.

If these numbers turn out to be right, I think Merrill is getting a better deal than did Home Depot's shareholders. For instance, at Home Depot (NYSE: HD), former CEO Bob Nardelli got $450 million -- a $210 million going away package plus $240 million in salary and other compensation -- and its stock was down 8% during his six-year tenure. By contrast, Merrill's stock is up 59% since O'Neal took over on December 2, 2002 -- creating $20.9 billion in additional shareholder value.

This sounds good in an absolute sense but it's not so great when viewed relative to other investments. Merrill's return under O'Neal is 9% less than that of the S&P 500 during the period and 217% below the return of competitor Goldman Sachs Group (NYSE: GS) since December 2002. If we credit O'Neal for the 59% return, then his $319 million pay generated a 65.5x return on investment -- including the additional $4.4 billion in shareholder value created by Friday's announcement that O'Neal was probably leaving -- which caused Merrill's stock to rise 8.5%.
