The Reckoning: Citigroup Pays for a Rush to Risk

By ERIC DASH and JULIE CRESWELL

“Our job is to set a tone at the top to incent people to do the right thing and to set up safety nets to catch people who make mistakes or do the wrong thing and correct those as quickly as possible. And it is working. It is working.”

In September 2007, with Wall Street confronting a crisis caused by too many souring mortgages, Citigroup executives gathered in a wood-paneled library to assess their own well-being.

There, Citigroup’s chief executive, Charles O. Prince III, learned for the first time that the bank owned about $43 billion in mortgage-related assets. He asked Thomas G. Maheras, who oversaw trading at the bank, whether everything was O.K.

Mr. Maheras told his boss that no big losses were looming, according to people briefed on the meeting who would speak only on the condition that they not be named.
