Detail about Prince

Prince graduated from the University of Southern California law school in 1975 and took a job at U.S. Steel Corp. In 1979, he joined Commercial Credit, where Weill became chairman in 1986.

After he took over Citigroup, Prince spent much of his first two years focused on cleaning up a slew of ethical and regulatory problems at the bank. Citigroup had already paid $400 million in the Wall Street stock research scandal.

He wrestled with issues including Citigroup's role in the collapses of Enron Corp. and WorldCom Inc., a scandal over its Japanese private bank, and a rogue bond trade that upended European markets.

Citigroup paid out more than $5 billion to resolve investigations. In 2005, the Federal Reserve barred it from big acquisitions for a year, but lifted the ban in April 2006 after Prince's campaign to clean up internal ethics bore fruit.

Prince turned his focus toward improving performance, and bolstering business outside the United States.
