Threadneedle Brand Introduced to U.S.

Leading U.K.-based asset manager enhances U.S. presence
LONDON--(Business Wire)--
Threadneedle, a leading global asset manager based in London, has
come to America. Four RiverSource mutual funds have been rebranded
under the Threadneedle name to bring greater clarity to the
comprehensive investment platform offered by RiverSource Investments.
The name change helps differentiate funds managed solely by
RiverSource from those that are subadvised by Threadneedle
International Limited and other partners.

"We are excited to establish the Threadneedle name and brand in
the U.S. marketplace as we continue to expand our global presence,"
said William Lowndes, head of U.S. distribution for Threadneedle
Investments. "Our goal is to provide U.S. retail and institutional
investors with broader access to our comprehensive investment
capabilities."

As of Dec. 31, 2007, the Threadneedle group of companies manages
more than $137 billion of assets and delivers services to clients in
15 countries with a team of more than 130 talented investment
professionals all centrally based in London. Threadneedle and
RiverSource Investments are both wholly-owned subsidiaries of
Ameriprise Financial, Inc., (NYSE: AMP).

"There is an increasing awareness of the role that global
investing can play in an individual's portfolio," said Patrick
Bannigan, senior vice president of mutual funds at RiverSource
Investments. "Global investing has long been one of Threadneedle's
core capabilities."

The four U.S. retail funds managed by Threadneedle are now named:

-- Threadneedle Emerging Markets Fund (formerly RiverSource
Emerging Markets Fund)

-- Threadneedle European Equity Fund (formerly RiverSource
European Equity Fund)

-- Threadneedle Global Equity Fund (formerly RiverSource Global
Equity Fund)

-- Threadneedle International Opportunity Fund (formerly
RiverSource International Opportunity Fund)

The funds are available through Ameriprise financial advisors and
non-affiliated banks and broker-dealers.

In 2007, Threadneedle delivered its strongest year ever for U.K.
equity investment performance, with 80 percent of equity funds above
the median of their respective S&P peer groups at year end.
Threadneedle won 2008 U.K. Lipper Fund Awards for Best Overall Group
and Best U.K. Equity Group, both in the large category.(a)

Management Limited, which shares all investment staff with
Threadneedle International Limited. These U.K. funds are not available
for sale in the U.S.
