Top Citi executive steps down

Michael Klein, vice chairman of Citigroup Inc. and chairman of its institutional-clients group, is leaving to pursue other opportunities, ending his 23-year career with the company.

He had held both positions since March.

Prior to that, Mr. Klein was chairman and co-chief executive of markets and banking, responsible for global corporate and investment banking.

In a statement, Citigroup chief executive Vikram Pandit thanked him for making “invaluable contributions” to the company and for being instrumental in its “growth and success.”

It isn’t clear who will succeed Mr. Klein. Citigroup representatives didn’t immediately return a phone call seeking comment.
