Citigroup today appointed its fifth chief financial officer in four-and-a-half years in a top management reshuffle that saw the chairman of its non-core assets group depart for family time in Utah, and its incumbent finance chief handed a broader strategic role. The shakeup means that 60% of the bank's 43 most senior executives have left since 2006.

Departing is former chief financial officer Gary Crittenden, who in March was moved to be chairman of Citi Holdings, the entity created for non-core assets the company is looking to shed. Citi said in a statement Thursday Crittenden wanted to move to Utah "to devote more time to his family and other business interests." The announcement does not name a replacement.
