The information following the second paragraph in the Investment Manager section
has been revised as follows:

Portfolio Manager(s).  The portfolio manager responsible for the day-to-day
management of the Fund is:

John K. Schonberg, CFA, Portfolio Manager

-   Managed the Fund since November 2008.

-   Equity Team Leader.

-   Joined RiverSource Investments in 1997.

-   Began investment career in 1988.

-   BS, University of Nebraska.

It is anticipated that Mr. Schonberg's role will be transitional, pending close
of RiverSource Investments acquisition of J. & W. Seligman & Co., Inc., after
which a long-term management plan will be implemented (expected before the end
of November 2008).

The rest of the section remains unchanged.
