RIVERSOURCE GLOBAL BOND FUND (THE FUND)

The first paragraph under the caption Principal Investment Strategies is hereby
replaced with the following:

The Fund is a non-diversified mutual fund that invests primarily in debt
obligations of U.S. and foreign issuers. Under normal market conditions, at
least 80% of the Fund's net assets will be invested in investment-grade
corporate or government debt obligations, including money market instruments, of
issuers located in at least three different countries. Although the Fund
emphasizes high and medium-quality debt securities, it may assume some credit
risk in seeking to achieve higher dividends and /or capital appreciation by
buying below investment-grade bonds (junk bonds). The Fund will provide
shareholders with at least 60 days' written notice of any change in the 80%
policy.

Under normal market conditions, the Fund generally will invest at least 40% of
its net assets in debt obligations of foreign governments, and companies that
(a) maintain their principal place of business or conduct their principal
business activities outside the U.S., (b) have their securities traded on non-
U.S. exchanges or (c) have been formed under the laws of non-U.S. countries. The
investment manager may reduce this 40% minimum investment amount to 30% if it
believes that market conditions for these securities or specific foreign markets
are unfavorable. The Fund considers a company to conduct its principal business
activities outside the U.S. if it derives at least 50% of its revenue from
business outside the U.S. or had at least 50% of its assets outside the U.S.

THREADNEEDLE GLOBAL EQUITY INCOME FUND (THE FUND)

assets in equity securities. The securities in which the Fund invests will
typically include dividend-paying common and preferred stocks that produce
current income or that offer potential to produce income. The Fund may invest in
equity securities of companies located in developed and emerging markets. The
Fund may invest in any economic sector and, at times, it may emphasize one or
more particular sectors. The Fund will provide shareholders with at least 60
days' written notice of any change in the 80% policy.

THREADNEEDLE GLOBAL EXTENDED ALPHA FUND (THE FUND)

The first paragraph under the caption Principal Investment Strategies is hereby
replaced with the following:

Under normal market conditions, the Fund will invest primarily in equity
securities, including at least 40% of its net assets in companies that maintain
their principal place of business or conduct their principal business activities
outside the U.S., have their securities traded on non-U.S. exchanges or have
been formed under the laws of non-U.S. countries. The investment manager may
reduce this 40% minimum investment amount to 30% if it believes that market
conditions for these securities or specific foreign markets are unfavorable. The
Fund considers a company to conduct its principal business activities outside
the U.S. if it derives at least 50% of its revenue from business outside the
U.S. or had at least 50% of its assets outside the U.S. The Fund may invest in
equity securities of companies located in developed and emerging markets. The
Fund will hold both long and short positions. A long position is an ordinary
purchase of a security. When the Fund takes a short position, it sells a
security that it has borrowed in anticipation of a decline in the price of the
security. The investment manager is able to invest the proceeds from its short
positions in additional long positions, 'extending' the equity exposure of the
Fund in an effort to achieve an enhanced level of 'alpha.' Alpha represents how
much the Fund's return is attributable to the investment manager's ability to
deliver above-average returns, adjusted for risk. To complete a short sale
transaction, the Fund buys back the same security in the market and returns it
to the lender. If the price of the security falls sufficiently, the Fund will
make money. If it instead increases in price, the Fund will lose money. Both
long and short positions may be obtained through buying or selling individual
securities or creating similar long or short exposure through the use of
derivative instruments.
