As part of the Bear Stearns culture, molded by the former chairman, Alan C. Greenberg, 1,000 senior managing directors gave away 4 percent of their compensation each year to charity.
Mr. Greenberg himself has been a major fund-raiser for the United Jewish Appeal. An annual September dinner at his home for top donors raised $41 million last year, according to the charity.
A number of Bear Stearns executives, including James E. Cayne, the former chief executive, have also given heavily through their own foundations. The James E. and Patricia D. Cayne Charitable Trust held $30.9 million, largely in Bear Stearns stock, on May 31, 2007, the end of its last fiscal year, according to publicly filed documents.
