MINNEAPOLIS — February 16, 2006 — RiverSource Investments, LLC, a subsidiary of Ameriprise Financial, Inc. (NYSE:AMP), today launched six new mutual funds: three RiverSource Income Builder Series funds-of-funds, a small-cap value fund, an emerging markets bond fund and a floating rate fund. The funds are available through Ameriprise Financial's advisors and Ameriprise Financial retirement plans.

RiverSource Income Builder Series builds on the success of RiverSource^® Portfolio Builder Series and consists of three income-generating funds-of-funds with varying levels of risk and yield. The funds' objective is to maximize potential yield, protect against inflation and minimize risk.

"RiverSource Income Builder Series is a sophisticated and comprehensive income solution designed to help meet clients' evolving income needs," said Paula Meyer, president of RiverSource Funds.

RiverSource Income Builder's disciplined investment process is driven by the combined experience of RiverSource Investments' specialized investment teams. The teams incorporate a strategic asset allocation based on RiverSource Investments' proprietary asset allocation modeling and leverage the extensive capabilities of the company's Fixed Income team to over/under weight investments in certain categories.

Portfolio management and asset allocation for RiverSource Income Builder Series is provided by:

• RiverSource Investments Fixed Income team – leads asset class selection, provides qualitative review of monthly allocations and manages the underlying fixed income funds.
• RiverSource Investments Disciplined Equity and Asset Allocation Team - provides quantitative asset allocation modeling and manages certain underlying equity funds.

Fund Name	Equity Allocation	Fixed Income	Allocation Cash
RiverSourceSM Income Builder Basic Income Fund	10-30%	55-85%	5-15%
RiverSourceSM Income Builder Moderate Income Fund	10-35%	55-90%	0-10%
RiverSourceSM Income Builder Enhanced Income Fund	10-40%	60-90%	0-5%

"Our clients have a critical need for income within their investment portfolios," said Michelle Keeley, head of fixed income and senior equity leader for RiverSource Investments. "With the RiverSource Income Builder Series solution, investors have an investment that is designed to deliver high current income, protection against inflation and capital preservation over time. The appeal of this innovative product is that it is diversified and sophisticated, but easy for advisors and clients to use according to their individual risk tolerances."

In addition to RiverSource Income Builder Series, RiverSource Investments launched three additional mutual funds:

RiverSource Disciplined Small Cap Value Fund
This fund seeks to provide shareholders with long-term growth of capital by investing primarily in small-cap value stocks such as those included in the Russell 2000^® Value Index. The fund is managed by the Disciplined Equity and Asset Allocation team in Cambridge, using a quantitative process based on proprietary stock selection models and a proprietary optimizer designed to minimize volatility and to maximize risk-adjusted returns.

RiverSource Emerging Markets Bond Fund
This fund aims to add income potential over time by investing primarily in emerging markets debt securities. The fund has limited exposure to foreign currencies and employs a top-down country focused strategy. Country allocations are sized relative the benchmark, but will significantly over/under weight countries based on material fundamentals. The fund is managed by the Minneapolis-based Fixed Income team.

Similar to high yield debt, emerging market debt has low correlation to other fixed income sectors and asset classes.

RiverSource Floating Rate Fund
This fund's objective is to provide high current income that rises in response to increasing interest rates with capital preservation as a secondary goal. The fund primarily invests in floating rate debt instruments, including bank loans, adjustable rate mortgages and floating rate asset-based securities. The fund may also invest a portion of its assets in non-floating rate instruments, including a range of fixed income securities and short-term money market instruments for liquidity, diversification and incremental return. Managers include members of the Minneapolis-based Fixed Income team and the Los Angeles-based Bank Loan team and will utilize relative value analysis to determine sector allocation and focus on bottom-up credit selection for individual investments.

"RiverSource Income Builder Series and these three new RiverSource funds align with our goal of providing clients with a broad product suite and innovative solutions that can help them reach their goals," said Meyer.

Russell 2000^® Value Index measures the performance of those Russell 2000 companies with lower price-to-book ratios and lower forecasted growth values.

Stocks of small-capitalization companies involve substantial risk. Historically, these stocks have experienced greater price volatility than stocks of larger companies, and they can be expected to do so in the future.

International investing involves increased risk and volatility, not typically associated with domestic investing, due to changes in currency exchange rates, foreign government regulations, differences in auditing and accounting standards, potential political and economic instability, limited liquidity, and volatile prices. The risks of international investing are particularly significant in emerging markets.

There are risks associated with fixed income investments, including the impact of interest rates, credit, and inflation. In general, bond prices rise when interest rates fall and vice versa. This effect is usually more pronounced for longer-term securities.

The Floating Rate Fund invests primarily in floating rate loans, the market value of which may fluctuate, sometimes rapidly and unpredictably. The principal risks of investing in the fund include liquidity risk, interest rate risk, credit risk, counterparty risk, highly leveraged transactions risk, derivatives risk, confidential information access risk, and impairment of collateral risk. Generally, when interest rates rise, the prices of fixed income securities fall, however, securities or loans with floating interest rates can be less sensitive to interest rate changes, but they may decline in value if their interest rates do not rise as much as interest rates in general. Limited liquidity may affect the ability of the fund to purchase or sell floating rate loans and may have a negative impact on fund performance. The floating rate loans and securities in which the fund invests generally are lower-rated (non-investment grade) and are more likely to experience a default, which results in more volatile prices and more risk to principal and income than investment grade loans or securities. These and other risk considerations are discussed in detail in the fund's prospectus.

Investment products, including shares of mutual funds, are not federally or FDIC insured, are not deposits or obligations of, or guaranteed by, any financial institution and involve investment risks including possible loss of principal and fluctuation in value.

RiverSource^® Portfolio Builder Series and RiverSource Income Builder Series are "funds-of-funds" comprised of holdings in several different RiverSource funds, which may include small-cap, mid-cap, large-cap, money market, international, bond and/or sector funds. See the fund's prospectus for specific risks that may be associated with the underlying funds.

RiverSource Funds are managed by RiverSource Investments, LLC and distributed by Ameriprise Financial Services, Inc., Member FINRA. Both companies are part of Ameriprise Financial, Inc.
