DLJ Merchant Banking Partners, a private equity investment affiliate of Credit Suisse, has appointed Nicole Arnaboldi as chairman of DLJ MBP and its investment committee, in addition to her role as co-head of the illiquid alternatives group.

Steven Rattner, formerly the head of DLJ MBP, has decided to retire after more than 20 years at the bank.

“We are very pleased that Nicole will become the chairman of DLJ MBP,” said Rob Shafir, CEO of Credit Suisse's Asset Management Division. “One of the most experienced investors in the business, she brings to this role nearly 25 years of industry experience where she has established herself as a leader in private equity. Having been with DLJ in private equity for over 20 years, Nicole is well positioned to oversee the continued success and growth of this important middle market business and continue to provide excellent results for our investors.”
