A little more than a month after George Boutros jumped ship to join Frank Quattrone's Qatalyst Group, Credit Suisse has found a replacement, tapping Frederick Terrell to serve as vice chairman of the firm's investment banking group.

Terrell is arriving after serving as a managing partner and CEO of private equity firm Provender Capital Group. Terrell launched Provender back in 1996, alongside CS veteran Pilar Esperon. It is unknown what Terrell's departure will mean for the firm, which has invested in the likes of Carver Bancorp, the Walking Company, Vanguarde Media and the Diversity Channel, among others. One of Provender's more successful deals was its co-investment in Prestige Brands, alongside MidOcean Capital.

The firm's most recent fund was the 2002-vintage Provender Opportunities II. The fund was not a strong performer, according to documents from Calpers, a former limited partner that sold its stake through a secondary sale in 2008. Prior to unloading its position, Calpers reported that the fund had a net IRR of negative 46.8 percent.

Others have also defected from Provender. Ronald Mitchell, formerly a principal at the firm, left to launch Alumni Sports Enterprises.

For Terrell, Credit Suisse represents a return to where he started his career in finance, when he joined the First Boston Corp. in 1983. He quickly rose through the ranks, becoming a managing director and partner of Credit Suisse First Boston, where he had headed the mortgage finance group and served as a senior member of its principal transactions group.

A call to Credit Suisse was not immediately returned. A listing for Provender, which SEC filings indicate is based in Delaware, could not be immediately be found.
