Merrill's Thain is eligible for between $9 million and $11 million in stock holdings, if not more, Schmidt said. A person familiar with the situation at Merrill said that Thain's severance was not under discussion because Thain is still employed by Merrill Lynch.
Willumstad's decision to forgo some compensation was not exactly unique, however. In June, Fuld and Lehman President Bart McDade reportedly gave up their 2008 bonuses.
The year before, Kerry Killinger, the then-CEO of Washington Mutual, declined to take a bonus. Still, Killinger was "making [up] for lost time" when he stood to receive as much as $22 million in severance as he prepared to leave WaMu last month, according to Conde Nast Portfolio.com.
Attempts to reach Killinger were unsuccessful.
Killinger's salary and other compensation -- a total of $1.4 million by the end of 2007 -- was actually substantially lower than those of chief executives at other financial firms, including AIG's Willumstad. He earned $10.9 million in 2007, according to the California-based executive compensation firm Equilar.
Merrill's Thain, meanwhile, took home $15 million in 2007, according to Equilar, while former Merrill CEO Stanley O'Neal received $11.3 million and former Bear Stearns chief James Cayne, whose firm had the dubious distinction of receiving the first major government bailout of the year, received $11 million.
Fuld emerged as among the most highly paid Wall Street-ers, with a whopping $45.4 million in salary, bonuses and other compensation in 2007.
O'Neal declined a request for an interview. Attempts to reach Cayne were unsuccessful.
"What we've experienced over the last few years," said Reich, "is the same kind of anything goes get-rich quick executive compensation that we last saw in the late 1920s, and of course in 1929 we had the great crash."
Reich said that the cases in which executives cut back on their compensation were symbolic. Overall, he said, Americans shouldn't expect to see more chief executives cutting back on their own pay unless there's a "law requiring them to do so" -- like the measure under consideration by Congress and advocated by Frank and other elected officials.
Actions by the Federal Housing Finance Administration may prefigure compensation limits set by Congress.
Last week, the FHFA announced that it would not pay the former heads of mortgage giants Fannie Mae and Freddie Mac the packages that they were originally set to receive before the struggling companies were put into government conservatorship this summer.
The FHFA, clarifying information that it had previously released about compensation for former Freddie CEO Richard Syron and former Fannie CEO Daniel Mudd, told ABCNews.com that Syron would not receive $10.3 million in salary, bonus and payments in lieu of stock grants, as had originally been called for in his contract. He will, however, still receive $4 million in pension payments and 401(k) investments.
Mudd, the FHFA said, will not receive $2 million in salary and $300,000 in stock grants, as had originally been expected. But he will, the agency said, receive $5.6 million through his pension and 401(k) investments.
Overall, the two men, while still benefiting from seven-figure packages, will walk away with $12.6 million less than originally planned.
Syron's lawyer did not return a call for comment. Attempts to reach Mudd were unsuccessful.
