RiverSource Investments disciplined equity and asset allocation team, led by Dimitris Bertsimas, will replace Nick Thakore and Robert D. Ewing as managers of the $3.5 billion RiverSource Large Cap Equity fund, said Ryan Lund, spokesman.
Mr. Bertsimass team will continue to manage the $2.7 billion RiverSource Disciplined Equity fund and other mandates.
Messrs. Thakore and Ewing will join Putnam Investments on Nov. 3 to lead its large-cap equities team.
Erik Voss, the co-leader of the J.&W. Seligman core/growth equity team, will take over management of the $1.8 billion RiverSource Growth fund, which Mr. Thakore had overseen, when RiverSources pending acquisition of J.&W. Seligman closes next month, said Mr. Lund.
The contrarian equity team, led by senior portfolio manager Warren Spitz, will take over two funds which Messrs. Thakore and Ewing had worked on: the equity portion of the RiverSource Balanced fund, which has more than $1 billion of mutual fund and variable annuity assets, and the $47 million RiverSource Large Cap Value fund. Mr. Spitzs team will continue to look after its existing mandates, including the $5.8 billion RiverSource Diversified Equity fund.
Richard Parower, a portfolio manager with the Seligman Technology group, will replace Messrs. Thakore and Ewing on the $108 million RiverSource Global Technology fund.
