William Donaldson will be retiring from his post as chairman of the U.S. Securities and Exchange Commission June 30.[@@]
Donaldson, who turns 74 Thursday, said he will be returning to the private sector, but, at press time, he had not given any details about his next job.
Donaldson took over as head of the SEC in 2003, at a time when the collapse of Enron Corp., Houston, had shaken the faith of investors in securities regulation.
