OAKS, Pa., May 19 /PRNewswire-FirstCall/ -- SEI (Nasdaq: SEIC) today announced that it has been selected by the recently-established Riverfront Investment Group, LLC to provide operations outsourcing services for the firm's separate account business. Riverfront, which was recently founded by four highly-regarded former Wachovia Securities senior executives, selected SEI following a comprehensive evaluation process.

Riverfront also pointed to SEI's comprehensive outsourcing solutions and expertise across investment product lines as a strong differentiator given the firm's anticipated growth strategy.

"SEI is clearly the leader in the investment manager outsourcing space, which they consistently demonstrated throughout the selection process," said Pete Quinn, Riverfront's Chief Operating Officer. "In SEI we have a partner with a proven solution to support a large number of accounts across multiple sponsor platforms in an automated fashion.
