   from a "diversified" fund to a "non-diversified" fund, as
   such terms are defined under the Investment Company Act
   of 1940, as amended (the "1940 Act").

- --------------------------------------------------------------------------------------------------------
</Table>

These proposals will be considered by shareholders of the Selling Funds and
Minnesota Tax-Exempt Fund at a special joint meeting of such shareholders (the
"Meeting") that will be held at 10:00 a.m. on Jan. 29, 2008, in the Marquette
Hotel, 710 Marquette Avenue, Minneapolis, Minnesota 55402. Each of the Minnesota
Tax-Exempt Fund, the Selling Funds and the Buying Funds (collectively, the
"Funds") is a series of a registered open-end management investment company.
Please read this proxy statement/prospectus and keep it for future reference.

Although the Board of Directors/Trustees of each of the Funds (the "Board")
proposes that each Selling Fund merge with the corresponding Buying Fund, the
reorganization of each Selling Fund (each a "Reorganization") is not conditioned
upon the Reorganization of any other Selling Fund. Accordingly, if shareholders
of one Selling Fund approve its Reorganization, but shareholders of another
Selling Fund do not approve that Fund's Reorganization, it is expected that the
Reorganization of the approved Selling Fund will take place as described in this
proxy statement/prospectus.

HOW EACH REORGANIZATION WILL WORK

- - Each Selling Fund will transfer all of its assets to the corresponding Buying
  Fund in exchange for shares of such Buying Fund ("Reorganization Shares") and
  the assumption of all of the Selling Fund's liabilities.

- - Each Buying Fund will issue Reorganization Shares in an amount equal to the
  value of the assets of the shares that it receives from the Selling Fund, less
  the liabilities it assumes. The Reorganization Shares of each class will be
  distributed to the Selling Fund's shareholders of the corresponding class in
  proportion to their holdings in the Selling Fund. For example, holders of
  Class A shares of a Selling Fund will receive Class A shares of the
  corresponding Buying Fund with the same aggregate net asset value as their
  Selling Fund shares at the time of the Reorganization. You will not pay any
  sales charge in connection with this distribution of shares. If you already
  have a Buying Fund account, shares distributed in the Reorganization will be
  added to that account. As a result, when average cost is calculated for income
  tax purposes, the cost of the shares in the two accounts you owned will be
  combined.

SECTION A -- REORGANIZATION PROPOSALS

The following information describes the proposed reorganization of each Selling
Fund into a corresponding Buying Fund.

SUMMARY

This proxy statement/prospectus is being used by each Selling Fund to solicit
proxies to vote at a joint special meeting of shareholders. Shareholders of each
Selling Fund will consider a proposal to approve the Agreement and Plan of
Reorganization (the "Agreement") providing for the Reorganization of their
Selling Fund into the corresponding Buying Fund. A form of the Agreement is
included as Exhibit A.

The following is a summary. More complete information appears later in this
proxy statement/prospectus. You should read the entire proxy
statement/prospectus and the exhibits because they contain details that are not
in this summary.

HOW EACH REORGANIZATION WILL WORK

- - Each Selling Fund will transfer all of its assets to the corresponding Buying
  Fund in exchange for shares of such Buying Fund ("Reorganization Shares") and
  the assumption of all of the Selling Fund's liabilities.

- - Each Buying Fund will issue Reorganization Shares in an amount equal to the
  value of the assets of the shares that it receives from the Selling Fund, less
  the liabilities it assumes. The Reorganization Shares of each class will be
  distributed to the Selling Fund's shareholders of the corresponding class in
  proportion to their holdings in the Selling Fund. For example, holders of
  Class A shares of a Selling Fund will receive Class A shares of the
  corresponding Buying Fund with the same aggregate net asset value as their
  Selling Fund shares at the time of the Reorganization. You will not pay any
  sales charge in connection with this distribution of shares. If you already
  have a Buying Fund account, shares distributed in the Reorganization will be
  added to that account. As a result, when average cost is calculated for income
  tax purposes, the cost of the shares in the two accounts you owned will be
  combined.

- - As part of the Reorganization, systematic transactions (such as bank
  authorizations and systematic payouts) currently set up for your Selling Fund
  account may be transferred to your new Buying Fund account. Please contact
  your financial institution for additional details.

- - Neither the Selling Fund nor the shareholders of the Selling Fund will pay any
  sales charge in connection with the Reorganization.

- - After the Reorganization is completed, current Selling Fund shareholders will
  be shareholders of the Buying Fund. The Selling Fund will be terminated.

FEES AND EXPENSES

The following tables describe the fees and expenses that you pay if you buy and
hold shares of the Selling Fund or shares of the Buying Fund. The table also
shows pro forma expenses of the Buying Fund assuming the proposed Reorganization
had been effective at the beginning of the most recent fiscal year, adjusted to
reflect current fees, as applicable. The fees and expenses below exclude the
costs of this Reorganization, because these will be paid by RiverSource
Investments, LLC ("RiverSource Investments" or "investment manager") and its
affiliates.

(a)  Includes the impact of a performance incentive adjustment fee that
     increased the management fee by 0.001% for the most recent fiscal year. The
     index against which Fundamental Growth Fund's performance is measured for
     purposes of determining the performance incentive adjustment is the Lipper
     Large-Cap Growth Funds Index.
(b)  Other expenses include an administrative services fee, a transfer agency
     fee, a custody fee, other nonadvisory expenses and, for Class R4, a plan
     administration services fee. Other expenses may also include fees and
     expenses of affiliated and unaffiliated funds (acquired funds) which the
     Fund indirectly bears when it invests in the acquired funds. Because
     acquired funds will have varied expense and fee levels and the Fund may own
     different proportions of acquired funds at different times, the amount of
     fees and expenses incurred by the Fund with respect to such investments
     will vary.
(c)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until May 31, 2008,
     unless sooner terminated at the discretion of Fundamental Growth Fund's
     Board. Any amounts waived will not be reimbursed by Fundamental Growth
     Fund. Under this agreement, net Fundamental Growth Fund expenses (excluding
     fees and expenses of acquired funds), before giving effect to any
     performance incentive adjustment, will not exceed 1.42% for Class A, 2.18%
     for Class B, 2.18% for Class C, 0.99% for Class I and 1.29% for Class R4.
(d)  Includes the impact of a performance incentive adjustment fee that
     increased the management fee by 0.09% for the most recent fiscal year. The
     index against which Growth Fund's performance is measured for purposes of
     determining the performance incentive adjustment is the Lipper Large-Cap
     Growth Funds Index.
(e)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until July 31, 2008,
     unless sooner terminated at the discretion of Growth Fund's Board. Any
     amounts waived will not be reimbursed by Growth Fund. Under this agreement,
     net Growth Fund expenses (excluding fees and expenses of acquired funds),
     before giving effect to any performance incentive adjustment, will not
     exceed 0.97% for Class R4.

(a)  In September 2006, the Board approved renaming Class Y as Class R4,
     terminating the shareholder servicing agreement, revising the fee structure
     under the transfer agent agreement from account-based to asset-based, and
     adopting a plan administration services agreement.
(b)  Includes the impact of a performance incentive adjustment fee that
     decreased the management fee by 0.002% for the most recent fiscal year. The
     index against which International Equity Fund's performance is measured for
     purposes of determining the performance incentive adjustment is the Lipper
     International Funds Index.
(c)  Other expenses include an administrative services fee, a transfer agency
     fee, a custody fee, other nonadvisory expenses and, for Class R4, a plan
     administration services fee. Other expenses may also include fees and
     expenses of affiliated and unaffiliated funds (acquired funds) which the
     Fund indirectly bears when it invests in the acquired funds. Because
     acquired funds will have varied expense and fee levels and the Fund may own
     different proportions of acquired funds at different times, the amount of
     fees and expenses incurred by the Fund with respect to such investments
     will vary.
(d)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until Oct. 31, 2007,
     unless sooner terminated at the discretion of International Equity Fund's
     Board. Any amounts waived will not be reimbursed by International Equity
     Fund. Under this agreement, net International Equity Fund expenses
     (excluding fees and expenses of acquired funds), before giving effect to
     any performance incentive adjustment, will not exceed 1.60% for Class A,
     2.37% for Class B, 2.37% for Class C, 1.25% for Class I and 1.43% for Class
     R4.

(e)  Disciplined International Equity Fund's management fee may be increased or
     decreased due to the effect of a performance incentive adjustment. During
     the period May 18, 2006 (when shares became publicly available) to Oct. 31,
     2006, the management fee was not adjusted. The index against which
     Disciplined International Equity Fund's performance is measured for
     purposes of determining the performance incentive adjustment is the Lipper
     International Large-Cap Core Funds Index.
(f)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until Oct. 31, 2007,
     unless sooner terminated at the discretion of Disciplined International
     Equity Fund's Board. Any amounts waived will not be reimbursed by
     Disciplined International Equity Fund. Under this agreement, net
     Disciplined International Equity Fund expenses (excluding fees and expenses
     of acquired funds), before giving effect to any performance incentive
     adjustment, will not exceed 1.50% for Class A, 2.27% for Class B, 2.27% for
     Class C, 1.15% for Class I and 1.33% for Class R4.
(g)  Effective Nov. 1, 2007, the investment manager and its affiliates have
     contractually agreed to waive certain fees and to absorb certain expenses
     until Oct. 31, 2008, unless sooner terminated at the discretion of
     Disciplined International Equity Fund's Board. Any amounts waived will not
     be reimbursed by Disciplined International Equity Fund. Under this
     agreement, net Disciplined International Equity Fund expenses (excluding
     fees and expenses of acquired funds), before giving effect to any
     performance incentive adjustment, will not exceed 1.50% for Class A, 2.26%
     for Class B, 2.26% for Class C, 1.12% for Class I and 1.37% for Class R4.

EXAMPLE EXPENSES: These examples are intended to help you compare the cost of
investing in the Fund with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the Fund for the time periods and
then redeem all of your shares at the end of those periods indicated under the
current arrangements and if the proposed Reorganization had been in effect.
These examples also assume that your investment has a 5% return each year and
that the Fund's operating expenses remain the same. Although your actual costs
may be higher or lower, based on these assumptions your costs would be:

(a)  Effective Dec. 11, 2006, the following changes were implemented: renaming
     Class Y as Class R4, terminating the shareholder servicing agreement,
     revising the fee structure under the transfer agent agreement from
     account-based to asset-based, and adopting a plan administration services
     agreement.
(b)  Includes the impact of a performance incentive adjustment fee that
     decreased the management fee by 0.01% for the most recent fiscal year. The
     index against which Value Fund's performance is measured for purposes of
     determining the performance incentive adjustment is the Lipper Large-Cap
     Value Funds Index.
(c)  Other expenses include an administrative services fee, a transfer agency
     fee, a custody fee, other nonadvisory expenses and, for Class R4, a plan
     administration services fee. Other expenses may also include fees and
     expenses of affiliated and unaffiliated funds (acquired funds) which the
     Fund indirectly bears when it invests in the acquired funds. Because
     acquired funds will have varied expense and fee levels and the Fund may own
     different proportions of acquired funds at different times, the amount of
     fees and expenses incurred by the Fund with respect to such investments
     will vary.
(d)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until May 31, 2008,
     unless sooner terminated at the discretion of Value Fund's Board. Any
     amounts waived will not be reimbursed by Value Fund. Under this agreement,
     net Value Fund expenses (excluding fees and expenses of acquired funds),
     before giving effect to any performance incentive adjustment, will not
     exceed 1.23% for Class A, 1.99% for Class B, 1.99% for Class C, 0.84% for
     Class I and 1.10% for Class R4.
(e)  Includes the impact of a performance incentive adjustment fee that
     increased the management fee by 0.10% for the most recent fiscal year. The
     index against which Diversified Equity Income Fund's performance is
     measured for purposes of determining the performance incentive adjustment
     is the Lipper Equity Income Funds Index.
(f)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until Sept. 30, 2007,
     unless sooner terminated at the discretion of Diversified Equity Income
     Fund's Board. Any amounts waived will not be reimbursed by Diversified
     Equity Income Fund. Under this agreement, net Diversified Equity Income
     Fund expenses, before giving effect to any performance incentive
     adjustment, will not exceed 0.89% for Class R4.

TAX CONSEQUENCES

Each Reorganization is expected to be tax-free for federal income tax purposes
and will not take place unless the Selling Fund and the corresponding Buying
Fund receive a satisfactory opinion of tax counsel, substantially to that
effect. Accordingly, no gain or loss is expected to be recognized by the Selling
Fund or its shareholders as a direct result of a Reorganization. However,
because the Reorganization will end the tax year of each Selling Fund, it will
accelerate distributions to shareholders from the Selling Fund for its short tax
year ending on the date of the Reorganization. Those tax year-end distributions,
which are taxable, will include any net capital gains realized prior to the
implementation of a Reorganization and not previously distributed. At any time
prior to the consummation of a Reorganization, a shareholder may redeem shares.
This would likely result in recognition of gain or loss to the shareholder for
federal income tax purposes if the shareholder holds the shares in a taxable
account.

The tax basis and holding period of the shareholders' Selling Fund shares is
expected to carry over to the shareholders' new shares in the Buying Fund.

For more information about the federal income tax consequences of the
Reorganization, see the section entitled "Tax Status of the Reorganizations."

 24 RIVERSOURCE FUNDS -- PROXY STATEMENT


PROPOSAL 1. REORGANIZATION OF CORE BOND FUND INTO DIVERSIFIED BOND FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- - Have RiverSource Investments as an investment adviser.

- - Have the same policies for buying and selling shares and the same exchange
  rights.

- - Have the same distribution policies.

- - Offer the same classes of shares: Classes A, B, C, I, R2, R3, R4, R5 and W.

- - Are structured as a series of capital stock of an open-end management
  investment company organized as a Minnesota corporation.

COMPARISON OF INVESTMENT OBJECTIVES

The investment objectives for the Funds are as follows:

        SELLING FUND: Core Bond Fund seeks to provide shareholders with a high
                      total return through current income and capital
                      appreciation.

        BUYING FUND: Diversified Bond Fund seeks to provide shareholders with a
                     high level of current income while conserving the value of
                     the investment for the longest period of time.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund seeks to achieve its investment objective by investing 80% of its net
assets in bonds and other debt securities. The Selling Fund invests primarily,
and the Buying Fund invests at least 50%, in securities included in the Lehman
Brothers Aggregate Bond Index, which are investment grade and denominated in
U.S. dollars. Unlike the Selling Fund, which does not invest in securities rated
below investment grade, the Buying Fund may invest up to 50% in lower-quality
(junk) bonds. Each of the Selling Fund and the Buying Fund may invest up to 25%
in foreign investments, which may include investments in emerging markets. Both
Funds target an average portfolio duration within one year of the Lehman
Brothers Aggregate Bond Index.

Detailed strategies for the Selling Fund and the Buying Fund are set forth
below:

CORE BOND FUND (SELLING FUND):

Under normal market conditions, Core Bond Fund invests at least 80% of its net
assets in bonds and other debt securities. Although the Fund is not an index
fund, it invests primarily in securities like those included in the Lehman
Brothers Aggregate Bond Index (the Index), which are investment grade and
denominated in U.S. dollars. The Index includes securities issued by the U.S.
government, corporate bonds, and mortgage- and asset-backed securities. The Fund
will not invest in securities rated below investment grade, although it may hold
securities that have been downgraded. The Fund will provide shareholders with at
least 60 days' notice of any change in the 80% policy.

In pursuit of Core Bond Fund's objective, the investment manager chooses
investments by:

- - Evaluating the portfolio's total exposure to sectors, industries and
  securities relative to the Index.

- - Analyzing factors such as credit quality, interest rate outlook and price to
  select the most attractive securities within each sector (for example,
  identifying securities that have the opportunity to appreciate in value or
  provide income based on duration, expectations of changes in interest rates or
  credit quality).

- - Targeting an average portfolio duration within one year of the duration of the
  Index which, as of July 31, 2007, was 4.67 years. Duration measures the
  sensitivity of bond prices to changes in interest rates. The longer the
  duration of a bond, the longer it will take to repay the principal and
  interest obligations and the more sensitive it will be to changes in interest
  rates. For example, a five-year duration means a bond is expected to decrease
  in value by 5% if interest rates rise 1% and increase in value by 5% if
  interest rates fall 1%.

The Fund's investment process employs risk controls that are designed to
maintain risk levels comparable to the Index. These controls include review of
effective duration and limitation on sector allocations, industry concentration
and the size of individual positions.

In evaluating whether to sell a security, the investment manager considers,
among other factors:

- - The portfolio's total exposure to sectors, industries and securities relative
  to the Index.

- - Whether a security's rating has changed or is vulnerable to a change.

- - Whether a sector or industry is experiencing change.

- - Changes in the interest rate or economic outlook.

- - Identification of a more attractive opportunity.

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 25


The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, in an effort to produce
incremental earnings, to hedge existing positions, to increase market exposure
and investment flexibility, or to obtain or reduce credit exposure.

DIVERSIFIED BOND FUND (BUYING FUND):

Under normal market conditions, Diversified Bond Fund invests at least 80% of
its net assets in bonds and other debt securities. At least 50% of the Fund's
net assets will be invested in securities like those included in the Lehman
Brothers Aggregate Bond Index (the Index), which are investment grade and
denominated in U.S. dollars. The Index includes securities issued by the U.S.
government, corporate bonds, and mortgage- and asset-backed securities. Although
the Fund emphasizes high- and medium-quality debt securities, it will assume
some credit risk in an effort to achieve higher yield and/or capital
appreciation by buying lower-quality (junk) bonds. Up to 25% of the Fund's net
assets may be invested in foreign investments, which may include investments in
emerging markets. The Fund will provide shareholders with at least 60 days'
notice of any change in the 80% policy.

The selection of debt obligations is the primary decision in building the
investment portfolio. In pursuit of Diversified Bond Fund's objective, the
investment manager chooses investments by:

- - Evaluating the portfolio's total exposure to sectors, industries and
  securities relative to the Index.

- - Analyzing factors such as credit quality, interest rate outlook and price in
  seeking to select the most attractive securities within each sector.

- - Investing in lower-quality (junk) bonds and foreign investments as attractive
  opportunities arise.

- - Targeting an average portfolio duration within one year of the duration of the
  Index which, as of Aug. 31, 2007 was 4.64 years. Duration measures the
  sensitivity of bond prices to changes in interest rates. The longer the
  duration of a bond, the longer it will take to repay the principal and
  interest obligations and the more sensitive it will be to changes in interest
  rates. For example, a five-year duration means a bond is expected to decrease
  in value by 5% if interest rates rise 1% and increase in value by 5% if
  interest rates fall 1%.

In evaluating whether to sell a security, the investment manager considers,
among other factors:

- - Identification of more attractive investments based on relative value.

- - The portfolio's total exposure to sectors, industries and securities relative
  to the Index.

- - Whether a security's rating has changed or is vulnerable to a change.

- - Whether a sector or industry is experiencing change.

- - Changes in the interest rate or economic outlook.

The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, in an effort to produce
incremental earnings, to hedge existing positions, to increase market exposure
and investment flexibility, or to obtain or reduce credit exposure.

BOTH FUNDS:

- - Other Investment Strategies. In addition to the principal investment
  strategies previously described, the Fund may utilize investment strategies
  that are not principal investment strategies, including investment in
  affiliated and non-affiliated pooled investment vehicles (including mutual
  funds and exchange traded funds (ETFs), also referred to as "acquired funds")
  ownership of which results in the Fund bearing its proportionate share of the
  acquired funds' fees and expenses. Although ETFs are designed to replicate the
  price and yield of a specified market index, there is no guarantee that an ETF
  will track its specified market index, which may result in a loss. For more
  information on strategies and holdings, and the risks of such strategies,
  including derivative instruments that the Fund may use, see the Merger SAI and
  the Fund's annual and semiannual reports.

- - Unusual Market Conditions. During unusual market conditions, the Fund may
  temporarily invest more of its assets in money market securities than during
  normal market conditions. Although investing in these securities would serve
  primarily to avoid losses, this type of investing also could prevent the Fund
  from achieving its investment objective. During these times, the portfolio
  managers may make frequent securities trades that could result in increased
  fees, expenses and taxes, and decreased performance. Instead of investing in
  money market securities directly, the fund may invest in shares of an
  affiliated money market fund.

- - Securities Transaction Commissions. Securities transactions involve the
  payment by the Fund of brokerage commissions to broker-dealers, on occasion as
  compensation for research or brokerage services (commonly referred to as "soft
  dollars"), as the portfolio managers buy and sell securities for the Fund in
  pursuit of its objective. A description of the policies governing

 26 RIVERSOURCE FUNDS -- PROXY STATEMENT


  the Buying Fund's securities transactions and the dollar value of brokerage
  commissions paid by the Buying Fund is set forth in the Merger SAI. Funds that
  invest primarily in fixed income securities do not typically generate
  brokerage commissions that are used to pay for research or brokerage services.
  The brokerage commissions set forth in the Merger SAI do not include implied
  commissions or mark-ups (implied commissions) paid by the Buying Fund for
  principal transactions (transactions made directly with a dealer or other
  counterparty), including most fixed income securities (and certain other
  instruments, including derivatives). Brokerage commissions do not reflect
  other elements of transaction costs, including the extent to which the Fund's
  purchase and sale transactions may cause the market to move and change the
  market price for an investment.

  Although brokerage commissions and implied commissions are not reflected in
  the expense table under "Fees and Expenses," they are reflected in the total
  return of the Fund.

- - Portfolio Turnover. Trading of securities may produce capital gains, which are
  taxable to shareholders when distributed. Active trading may also increase the
  amount of brokerage commissions paid or mark-ups to broker-dealers that the
  Fund pays when it buys and sells securities. Capital gains and increased
  brokerage commissions or mark-ups paid to broker-dealers may adversely affect
  a fund's performance. The Buying Fund's historical portfolio turnover rate,
  which measures how frequently the Buying Fund buys and sells investments, is
  shown in Section D -- "Financial Highlights."

- - Directed Brokerage. The Fund's Board of Directors (Board) has adopted a policy
  prohibiting the investment manager, or any subadviser, from considering sales
  of shares of the Fund as a factor in the selection of broker-dealers through
  which to execute securities transactions.

COMPARISON OF FUNDAMENTAL POLICIES

The Selling Fund and the Buying Fund have substantially similar fundamental
investment policies. The investment manager does not believe that the
differences between the fundamental investment policies will result in any
material difference in the way the Funds are managed.

If shareholders of the Selling Fund approve the Reorganization, they will be
subject to the fundamental investment policies of the Buying Fund.

The fundamental policies of the Funds are set forth below. Neither of the Funds
will:

- - Act as an underwriter (sell securities for others). However, under the
  securities laws, the Fund may be deemed to be an underwriter when it purchases
  securities directly from the issuer and later resells them.

- - Lend securities or participate in an interfund lending program if the total of
  all such loans would exceed 33 1/3% of the Fund's total assets except this
  fundamental investment policy shall not prohibit the Fund from purchasing
  money market securities, loans, loan participation or other debt securities,
  or from entering into repurchase agreements.

- - Borrow money, except for temporary purposes (not for leveraging or investment)
  in an amount not exceeding 33 1/3% of its total assets (including the amount
  borrowed) less liabilities (other than borrowings) immediately after the
  borrowings.

- - Buy or sell real estate, unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  investing in securities or other instruments backed by real estate or
  securities of companies engaged in the real estate business or real estate
  investment trusts. For purposes of this policy, real estate includes real
  estate limited partnerships.

- - Buy or sell physical commodities unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  buying or selling options and futures contracts or from investing in
  securities or other instruments backed by, or whose value is derived from,
  physical commodities.

- - Purchase more than 10% of the outstanding voting securities of an issuer,
  except that up to 25% of the Fund's assets may be invested without regard to
  this 10% limitation.

- - Invest more than 5% of its total assets in securities of any company,
  government, or political subdivision thereof, except the limitation will not
  apply to investments in securities issued or guaranteed by the U.S.
  government, its agencies, or instrumentalities, or other investment companies,
  and except that up to 25% of the Fund's total assets may be invested without
  regard to this 5% limitation.

- - Concentrate in any one industry. According to the present interpretation by
  the Securities and Exchange Commission (SEC), this means that up to 25% of the
  Fund's total assets, based on current market value at time of purchase, can be
  invested in any one industry.

In addition, neither Fund may issue senior securities, except as permitted under
the 1940 Act.

COMPARISON OF NONFUNDAMENTAL POLICIES

Both Funds are also subject to the following nonfundamental policies:

- - Up to 25% of the Fund's net assets may be invested in foreign investments.

- - No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

COMPARISON OF PRINCIPAL RISK FACTORS

The Selling Fund and the Buying Fund are subject to similar principal risks.
Although the Buying Fund discloses liquidity as a principal risk, each of the
Selling Fund and the Buying Fund are exposed to liquidity risk. The Buying Fund
discloses liquidity risk as an increased exposure as a result of its ability to
invest in lower quality (junk) bonds.

The principal risks of investing in each of the Selling Fund and the Buying Fund
are shown below:

<Table>
<Caption>

PRINCIPAL RISK                                                  CORE BOND FUND    DIVERSIFIED BOND FUND

 Interest Rate Risk                                                   X                     X
 Liquidity Risk                                                                             X
 Market Risk                                                          X                     X
 Prepayment and Extension Risk                                        X                     X
</Table>

- - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers to make
  investment decisions that are suited to achieving the Fund's investment
  objective. Due to its active management, the Fund could underperform other
  mutual funds with similar investment objectives.

- - CREDIT RISK. Credit risk is the risk that the issuer of a security, or the
  counterparty to a contract, will default or otherwise become unable or
  unwilling to honor a financial obligation, such as payments due on a bond or a
  note. If the Fund purchases unrated securities, or if the rating of a security
  is reduced after purchase, the Fund will depend on the investment manager's
  analysis of credit risk more heavily than usual. For the Buying Fund,
  non-investment grade securities, commonly called "high-yield" or "junk" bonds,
  may react more to perceived changes in the ability of the issuing entity to
  pay interest and principal when due than to changes in interest rates.
  Non-investment grade securities have greater price fluctuations and are more
  likely to experience a default than investment grade bonds. Because the Buying
  Fund may invest in lower-rated (junk) bonds, it may be subject to greater
  credit risk than the Selling Fund.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  counterparty credit risk, leverage risk, hedging risk, correlation risk and
  liquidity risk. Counterparty credit risk is the risk that a counterparty to
  the derivative instrument becomes bankrupt or otherwise fails to perform its
  obligations due to financial difficulties, and the Fund may obtain no recovery
  of its investment or may only obtain a limited recovery, and any recovery may
  be delayed. Hedging risk is the risk that derivative instruments used to hedge
  against an opposite position may offset losses, but they may also offset
  gains. Correlation risk is related to hedging risk and is the risk that there
  may be an incomplete correlation between the hedge and the opposite position,
  which may result in increased or unanticipated losses. Liquidity risk is the
  risk that the derivative instrument may be difficult or impossible to sell or
  terminate, which may cause the Fund to be in a position to do something the
  investment manager would not otherwise choose, including, accepting a lower
  price for the derivative instrument, selling other investments or foregoing
  another, more appealing investment opportunity. Leverage risk is the risk that
  losses from the derivative instrument may be greater than the amount invested
  in the derivative instrument. Certain derivatives have the potential for
  unlimited losses, regardless of the size of the initial investment. See the
  Merger SAI for more information on derivative instruments and related risks.

- - INTEREST RATE RISK. Interest rate risk is the risk of losses attributable to
  changes in interest rates. Interest rate risk is generally associated with
  bond prices: when interest rates rise, bond prices fall. In general, the
  longer the maturity or duration of a bond, the greater its sensitivity to
  changes in interest rates.

- - LIQUIDITY RISK. The risk associated from a lack of marketability of securities
  which may make it difficult or impossible to sell at desirable prices in order
  to minimize loss. The Fund may have to lower the selling price, sell other
  investments, or forego another, more appealing investment opportunity.

- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably.

- - PREPAYMENT AND EXTENSION RISK. Prepayment and extension risk is the risk that
  a bond or other security might be called, or otherwise converted, prepaid, or
  redeemed, before maturity. This risk is primarily associated with asset-backed
  securities, including mortgage backed securities. If a security is converted,
  prepaid, or redeemed, before maturity, particularly during a

 28 RIVERSOURCE FUNDS -- PROXY STATEMENT


  time of declining interest rates, the investment manager may not be able to
  reinvest in securities providing as high a level of income, resulting in a
  reduced yield to the Fund. Conversely, as interest rates rise, the likelihood
  of prepayment decreases. The investment manager may be unable to capitalize on
  securities with higher interest rates because the Fund's investments are
  locked in at a lower rate for a longer period of time.

PERFORMANCE

The following bar chart and table provide some illustration of the risks of
investing in the Fund by showing, respectively:

- - how the Fund's performance has varied for each full calendar year shown on the
  bar chart; and

- - how the Fund's average annual total returns compare to recognized indexes
  shown on the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How the Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Chart. Class A share information is shown in the bar chart; the sales charge
for Class A shares is not reflected in the bar chart.

Table. The table shows total returns from hypothetical investments in Class A,
Class B, Class C, Class I and Class R4 shares of the Fund. These returns are
compared to the indexes shown for the same periods. For purposes of the
performance calculation in the table we assumed:

- - the maximum sales charge for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge (CDSC) for Class B and Class C shares;

- - no sales charge for Class I and Class R4 shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

PROPOSAL 2. REORGANIZATION OF FUNDAMENTAL GROWTH FUND INTO GROWTH FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- - Have RiverSource Investments as an investment adviser.

- - Are structured as a series of capital stock of an open-end management
  investment company organized as a Minnesota corporation.

- - Have the same policies for buying and selling shares and the same exchange
  rights.

- - Have the same distribution policies.

- - Offer classes A, B, C, I and R4 (the Buying Fund also offers classes R2, R3,
  R5 and W).

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds seek to provide shareholders with long-term capital growth.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

The Selling Fund and the Buying Fund have similar principal investment
strategies. Both Funds invest primarily in U.S. equity securities, although each
may invest up to 25% of its net assets in foreign investments. Although
RiverSource Investments serves as investment manager of both Funds, the Selling
Fund was, until Nov. 16, 2007, subadvised by Goldman Sachs Asset Management,
L.P. (GSAM) and Wellington Management Company, LLP (Wellington Management). The
Selling Fund's Board of Directors terminated the contracts of GSAM and
Wellington Management. Since Nov. 16, 2007, RiverSource Investments has solely
managed the Selling Fund. Current detailed strategies for the Selling Fund and
the Buying Fund are set forth below:

FUNDAMENTAL GROWTH FUND (SELLING FUND):

Fundamental Growth Fund invests primarily in common stocks and securities
convertible into common stocks that appear to offer growth opportunities. These
growth opportunities could result from new management, market developments, or
technological superiority. The Fund may invest up to 25% of its net assets in
foreign investments.

In pursuit of Fundamental Growth Fund's objective, the investment manager
chooses investments by identifying companies that the investment manager
believes have above-average long-term growth potential based, among other
factors, on:

- - Management's track record.

- - Financial strength.

- - Competitive market or product position.

- - Technological advantage (more advanced technology or proven technological
  advantage) over competitors.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- - The security is overvalued relative to other potential investments.

- - The security has reached the investment manager's price objective.

- - The company has met the investment manager's earnings and/or growth
  expectations.

- - The investment manager identifies a more attractive opportunity.

The investment manger may use derivatives such as futures, options, forward
contracts and structured investments, to produce incremental earnings, to hedge
existing positions, or to increase flexibility.

GROWTH FUND (BUYING FUND):

Growth Fund invests primarily in common stocks and securities convertible into
common stocks that appear to offer growth opportunities. These growth
opportunities could result from new management, market developments, or
technological superiority. The Growth Fund may invest up to 25% of its net
assets in foreign investments.

In pursuit of Growth Fund's objective, the investment manager chooses
investments by identifying companies that the investment manager believes have
above-average long-term growth potential based, among other factors, on:

- - Management's track record.

- - Financial strength.

- - Competitive market or product position.

- - Technological advantage (more advanced technology or proven technological
  advantage) over competitors.

 32 RIVERSOURCE FUNDS -- PROXY STATEMENT


In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- - The security is overvalued relative to other potential investments.

- - The security has reached the investment manager's price objective.

- - The company has met the investment manager's earnings and/or growth
  expectations.

- - The investment manager identifies a more attractive opportunity.

The investment manger may use derivatives such as futures, options, forward
contracts and structured investments, to produce incremental earnings, to hedge
existing positions, or to increase flexibility.

BOTH FUNDS:

- - Other Investment Strategies. In addition to the principal investment
  strategies previously described, the Fund may utilize investment strategies
  that are not principal investment strategies, including investment in
  affiliated and non-affiliated pooled investment vehicles (including mutual
  funds and exchange traded funds (ETFs), also referred to as "acquired funds")
  ownership of which results in the Fund bearing its proportionate share of the
  acquired funds' fees and expenses. Although ETFs are designed to replicate the
  price and yield of a specified market index, there is no guarantee that an ETF
  will track its specified market index, which may result in a loss. For more
  information on strategies and holdings, and the risks of such strategies,
  including derivative instruments that the Fund may use, see the Merger SAI and
  the Fund's annual and semiannual reports.

- - Unusual Market Conditions. During unusual market conditions, the Fund may
  temporarily invest more of its assets in money market securities than during
  normal market conditions. Although investing in these securities would serve
  primarily to attempt to avoid losses, this type of investing also could
  prevent the Fund from achieving its investment objective. During these times,
  the portfolio managers may make frequent securities trades that could result
  in increased fees, expenses and taxes, and decreased performance. Instead of
  investing in money market securities directly, the Fund may invest in shares
  of an affiliated money market fund.

- - Securities Transaction Commissions. Securities transactions involve the
  payment by the Fund of brokerage commissions to broker-dealers, on occasion as
  compensation for research or brokerage services (commonly referred to as "soft
  dollars"), as the portfolio managers buy and sell securities for the Fund in
  pursuit of its objective. A description of the policies governing the Buying
  Fund's securities transactions and the dollar value of brokerage commissions
  paid by the Buying Fund is set forth in the Merger SAI. The brokerage
  commissions set forth in the Merger SAI do not include implied commissions or
  mark-ups (implied commissions) paid by the Buying Fund for principal
  transactions (transactions made directly with a dealer or other counterparty),
  including most fixed income securities (and certain other instruments,
  including derivatives). Brokerage commissions do not reflect other elements of
  transaction costs, including the extent to which the Fund's purchase and sale
  transactions may cause the market to move and change the market price for an
  investment.

  Although brokerage commissions and implied commissions are not reflected in
  the expense table under "Fees and Expenses," they are reflected in the total
  return of the Fund.

- - Portfolio Turnover. Trading of securities may produce capital gains, which are
  taxable to shareholders when distributed. Active trading may also increase the
  amount of brokerage commissions paid or mark-ups to broker-dealers that the
  Fund pays when it buys and sells securities. For subadvised funds, a change in
  a subadviser may result in increased portfolio turnover, which increase may be
  substantial, as the new subadviser realigns the portfolio, or if the
  subadviser(s) trades portfolio securities more frequently. A realignment or
  more active strategy could produce higher than expected capital gains. Capital
  gains and increased brokerage commissions or mark-ups paid to broker-dealers
  may adversely affect a Fund's performance. The Buying Fund's historical
  portfolio turnover rate, which measures how frequently the Buying Fund buys
  and sells investments, is shown in Section D -- "Financial Highlights."

- - Directed Brokerage. The Fund's Board of Directors (Board) has adopted a policy
  prohibiting the investment manager, or any subadviser, from considering sales
  of shares of the Fund as a factor in the selection of broker-dealers through
  which to execute securities transactions.

COMPARISON OF FUNDAMENTAL POLICIES

The Selling Fund and the Buying Fund have substantially similar fundamental
investment policies. The investment manager does not believe that the
differences between the fundamental investment policies will result in any
material difference in the way the Funds are managed.

If shareholders of the Selling Fund approve the Reorganization, they will be
subject to the fundamental investment policies of the Buying Fund.

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 33


The fundamental policies of the Funds are set forth below. Neither of the Funds
will:

- - Act as an underwriter (sell securities for others). However, under the
  securities laws, the Fund may be deemed to be an underwriter when it purchases
  securities directly from the issuer and later resells them.

- - Lend securities or participate in an interfund lending program if the total of
  all such loans would exceed 33 1/3% of the Fund's total assets except this
  fundamental investment policy shall not prohibit the Fund from purchasing
  money market securities, loans, loan participation or other debt securities,
  or from entering into repurchase agreements.

- - Borrow money, except for temporary purposes (not for leveraging or investment)
  in an amount not exceeding 33 1/3% of its total assets (including the amount
  borrowed) less liabilities (other than borrowings) immediately after the
  borrowings.

- - The Fund will not buy or sell real estate, unless acquired as a result of
  ownership of securities or other instruments, except this shall not prevent
  the Fund from investing in securities or other instruments backed by real
  estate or securities of companies engaged in the real estate business or real
  estate investment trusts. For purposes of this policy, real estate includes
  real estate limited partnerships.

- - The Fund will not buy or sell physical commodities unless acquired as a result
  of ownership of securities or other instruments, except this shall not prevent
  the Fund from buying or selling options and futures contracts or from
  investing in securities or other instruments backed by, or whose value is
  derived from, physical commodities.

- - The Fund will not purchase more than 10% of the outstanding voting securities
  of an issuer, except that up to 25% of the Fund's assets may be invested
  without regard to this 10% limitation.

- - The Fund will not invest more than 5% of its total assets in securities of any
  company, government, or political subdivision thereof, except the limitation
  will not apply to investments in securities issued or guaranteed by the U.S.
  government, its agencies, or instrumentalities, or other investment companies,
  and except that up to 25% of the Fund's total assets may be invested without
  regard to this 5% limitation.

- - The Fund will not concentrate in any one industry. According to the present
  interpretation by the Securities and Exchange Commission (SEC), this means
  that up to 25% of the Fund's total assets, based on current market value at
  time of purchase, can be invested in any one industry.

In addition, neither Fund may issue senior securities, except as permitted under
the 1940 Act.

COMPARISON OF NONFUNDAMENTAL POLICIES

Both Funds are also subject to the following nonfundamental policies:

- - Up to 25% of the Fund's net assets may be invested in foreign investments.

- - No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

COMPARISON OF PRINCIPAL RISK FACTORS

The Selling Fund and the Buying Fund are subject to similar principal risks.

The principal risks of investing in each of the Selling Fund and the Buying Fund
are shown below:

 Small and Mid-Sized Company Risk                                          X                    X
</Table>

- - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers to select
  securities and to make investment decisions that are suited to achieving the
  Fund's investment objective. Due to its active management, the Fund could
  underperform other mutual funds with similar investment objectives.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to Principal Risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  counterparty credit risk, leverage risk, hedging risk, correlation risk, and
  liquidity risk. Counterparty credit risk is the risk that a counterparty to
  the derivative instrument becomes bankrupt or otherwise fails to perform its
  obligations due to financial difficulties, and the Fund may obtain no recovery
  of its investment or may only obtain a limited recovery, and any recovery may
  be delayed. Hedging risk is the risk that derivative instruments used

 34 RIVERSOURCE FUNDS -- PROXY STATEMENT


  to hedge against an opposite position may offset losses, but they may also
  offset gains. Correlation risk is related to hedging risk and is the risk that
  there may be an incomplete correlation between the hedge and the opposite
  position, which may result in increased or unanticipated losses. Liquidity
  risk is the risk that the derivative instrument may be difficult or impossible
  to sell or terminate, which may cause the Fund to be in a position to do
  something the investment manager would not otherwise choose, including
  accepting a lower price for the derivative instrument, selling other
  investments or foregoing another, more appealing investment opportunity.
  Leverage risk is the risk that losses from the derivative instrument may be
  greater than the amount invested in the derivative instrument. Certain
  derivatives have the potential for unlimited losses, regardless of the size of
  the initial investment. See the Merger SAI for more information on derivative
  instruments and related risks.

- - FOREIGN RISK. The following are all components of foreign risk:

  Country risk includes the political, economic, and other conditions of the
  country. These conditions include lack of publicly available information, less
  government oversight (including lack of accounting, auditing, and financial
  reporting standards), the possibility of government-imposed restrictions, and
  even the nationalization of assets. The liquidity of foreign investments may
  be more limited than for most U.S. investments, which means that, at times it
  may be difficult to sell foreign securities at desirable prices.

  Currency risk results from the constantly changing exchange rate between local
  currency and the U.S. dollar. Whenever the Fund holds securities valued in a
  foreign currency or holds the currency, changes in the exchange rate add to or
  subtract from the value of the investment.

  Custody risk refers to the process of clearing and settling trades. It also
  covers holding securities with local agents and depositories. Low trading
  volumes and volatile prices in less developed markets make trades harder to
  complete and settle. Local agents are held only to the standard of care of the
  local market. Governments or trade groups may compel local agents to hold
  securities in designated depositories that are not subject to independent
  evaluation. The less developed a country's securities market is, the greater
  the likelihood of problems occurring.

- - ISSUER RISK. An issuer may perform poorly, and therefore, the value of its
  stocks and bonds may decline. Poor performance may be caused by poor
  management decisions, competitive pressures, breakthroughs in technology,
  reliance on suppliers, labor problems or shortages, corporate restructurings,
  fraudulent disclosures or other factors.

- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably. This risk is generally greater for small and
  mid-sized companies, which tend to be more vulnerable to adverse developments.
  In addition, focus on a particular style, for example, investment in growth or
  value securities, may cause the Fund to underperform other mutual funds if
  that style falls out of favor with the market.

- - SMALL AND MID-SIZED COMPANY RISK. Investments in small and medium companies
  often involve greater risks than investments in larger, more established
  companies because small and medium companies may lack the management
  experience, financial resources, product diversification, experience and
  competitive strengths of larger companies. Additionally, in many instances the
  securities of small and medium companies are traded only over-the-counter or
  on regional securities exchanges and the frequency and volume of their trading
  is substantially less and may be more volatile than is typical of larger
  companies.

PERFORMANCE

The following bar chart and table provide some illustration of the risks of
investing in the Fund by showing, respectively:

- - how the Fund's performance has varied for each full calendar year shown on the
  bar chart; and

- - how the Fund's average annual total returns compare to recognized indexes
  shown on the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How the Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Chart. Class A share information is shown in the bar chart; the sales charge
for Class A shares is not reflected in the bar chart.

Table. The table shows total returns from hypothetical investments in Class A,
Class B, Class C, Class I and Class R4 shares of the Fund. These returns are
compared to the indexes shown for the same periods. For purposes of the
performance calculation in the table we assumed:

- - the maximum sales charge for Class A shares;
- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge (CDSC) for Class B and Class C shares;

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 35


- - no sales charge for Class I and Class R4 shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

PROPOSAL 3. REORGANIZATION OF INTERNATIONAL EQUITY FUND INTO DISCIPLINED
INTERNATIONAL EQUITY FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- - Have RiverSource Investments as an investment adviser.

- - Are structured as a series of capital stock of an open-end management
  investment company organized as a Minnesota corporation.

- - Have the same policies for buying and selling shares and the same exchange
  rights.

- - Have the same distribution policies.

- - Offer classes A, B, C, I and R4 (the Buying Fund also offers Class W).

COMPARISON OF INVESTMENT OBJECTIVES

Both Funds seek to provide shareholders with long-term growth of capital.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Both Funds invest primarily in equity securities of foreign issuers. Both Funds
may invest in securities of or instruments that provide exposure to both
developed and emerging markets issuers. Both Funds may invest in companies of
any size, and will typically invest in a blend of both value and growth stocks.
Although RiverSource Investments serves as investment manager of both Funds, the
Selling Fund was, until Nov. 16, 2007, subadvised by The Boston Company Asset
Management, LLC (Boston Company) and Marsico Capital Management, LLC (Marsico).
The Selling Fund's Board of Directors terminated the contracts of the Boston
Company and Marsico. Since Nov. 16, 2007, RiverSource Investments has solely
managed the Selling Fund. Detailed strategies for the Selling Fund and the
Buying Fund are set forth below:

INTERNATIONAL EQUITY FUND (SELLING FUND):

Under normal market conditions, at least 80% of International Equity Fund's
assets will be invested in equity securities. The Fund's assets are primarily
invested in equity securities of foreign issuers or in instruments that provide
exposure to foreign equity markets. The Fund may invest in securities of or
instruments that provide exposure to both developed and emerging markets
issuers. The Fund will provide shareholders with at least 60 days' notice of any
change in the 80% policy.

In pursuit of International Equity Fund's objective, the investment manager will
choose equity investments by employing proprietary, disciplined quantitative
methods.

The investment manager's disciplined quantitative approach is designed to
identify companies with:

- - Attractive valuations, based on factors such as price-to-earnings ratios;

- - Sound balance sheets; or

- - Improving outlooks, based on an analysis of return patterns over time.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- - The security is overvalued relative to other potential investments.

- - The company does not meet the investment manager's performance expectations.

The universe of stocks from which the investment manager selects the Fund's
investments primarily will be those included in the Fund's benchmark, the Morgan
Stanley Capital International (MSCI) EAFE Index (MSCI EAFE Index).

In selecting stocks for the Fund to purchase or to sell, the investment manager
also employs a rigorous process for evaluating the relationship between the risk
associated with each security and its potential for positive returns. This
process takes into account factors such as:

- - Limits on positions relative to weightings in the benchmark index.

- - Limits on country and region allocations relative to the benchmark index.

- - Limits on size of holdings relative to market liquidity.

The Fund will normally have exposure to foreign currencies. The investment
manager closely monitors the Fund's exposure to foreign currency. From time to
time, the investment manager may use forward currency transactions or other
derivative instruments on a limited basis to hedge against currency
fluctuations. The investment manager may also use derivative instruments, such
as options, futures, forward contracts, swaps or structured notes, to produce
incremental earnings, to increase flexibility, to gain exposure to a segment of
the market or to hedge against existing positions.

DISCIPLINED INTERNATIONAL EQUITY FUND (BUYING FUND):

Under normal market conditions, at least 80% of Disciplined International Equity
Fund's assets will be invested in equity securities of foreign issuers or in
instruments that provide exposure to foreign equity markets. The Fund may invest
in securities of or instruments that provide exposure to both developed and
emerging markets issuers. The Fund will provide shareholders with at least 60
days' notice of any change in the 80% policy.

as options, futures, forward contracts, swaps or structured notes, to produce
incremental earnings, to increase flexibility, to gain exposure to a segment of
the market or to hedge against existing positions.

BOTH FUNDS:

- - Other Investment Strategies. In addition to the principal investment
  strategies previously described, the Fund may invest in other securities and
  may use other investment strategies that are not principal investment
  strategies. Additionally, the Fund may use derivatives (financial instruments
  where the value depends upon, or is derived from, the value of something else)
  such as futures, options and forward contracts, to produce incremental
  earnings, to hedge existing positions or to increase flexibility. Just as with
  securities in which the Fund invests directly, derivatives are subject to a
  number of risks, including market, liquidity, interest rate and credit risk.
  In addition, a relatively small price movement in the underlying security,
  currency or index may result in a substantial gain or loss for the Fund using
  derivatives. Even though the Fund's policies permit the use of derivatives in
  this manner, the portfolio managers are not required to use derivatives. For
  more information on strategies and holdings, and the risks of such strategies,
  including other derivative instruments that the Buying Fund may use, see the
  Merger SAI.

- - Unusual Market Conditions. During unusual market conditions, the Fund may
  temporarily invest more of its assets in money market securities than during
  normal market conditions. Although investing in these securities would serve
  primarily to avoid losses, this type of investing also could prevent the Fund
  from achieving its investment objective. During these times, the portfolio
  managers may make frequent securities trades that could result in increased
  fees, expenses and taxes, and decreased performance. Instead of investing in
  money market securities directly, the Fund may invest in shares of an
  affiliated money market fund.

- - Portfolio Turnover. Trading of securities may produce capital gains, which are
  taxable to shareholders when distributed. Active trading may also increase the
  amount of brokerage commissions paid or mark-ups to broker-dealers that the
  Fund pays when it buys and sells securities. For subadvised funds, a change in
  the subadviser(s) may result in increased portfolio turnover, which increase
  may be substantial, as the new subadviser(s) realign the portfolio, or if the
  subadviser(s) trades portfolio securities more frequently. A realignment or
  more active strategy could produce higher than expected capital gains. Capital
  gains and increased brokerage commissions or mark-ups paid to broker-dealers
  may adversely affect a fund's

 40 RIVERSOURCE FUNDS -- PROXY STATEMENT


  performance. The Buying Fund's historical portfolio turnover rate, which
  measures how frequently the Buying Fund buys and sells investments, is shown
  in Section D -- "Financial Highlights."

- - Securities Transaction Commissions. Securities transactions involve the
  payment by the Fund of brokerage commissions to broker-dealers, on occasion as
  compensation for research or brokerage services (commonly referred to as "soft
  dollars"), as the portfolio managers buy and sell securities for the Fund in
  pursuit of its objective. A description of the policies governing the Buying
  Fund's securities transactions and the dollar value of brokerage commissions
  paid by the Buying Fund is set forth in the Merger SAI. The brokerage
  commissions set forth in the Merger SAI do not include implied commissions or
  mark-ups (implied commissions) paid by the Buying Fund for principal
  transactions (transactions made directly with a dealer or other counterparty),
  including most fixed income securities (and certain other instruments,
  including derivatives). Brokerage commissions do not reflect other elements of
  transaction costs, including the extent to which the Fund's purchase and sale
  transactions may cause the market to move and change the market price for an
  investment.

  Although brokerage commissions and implied commissions are not reflected in
  the expense table under "Fees and Expenses," they are reflected in the total
  return of the Fund.

- - Directed Brokerage. The Fund's Board of Directors (Board) has adopted a policy
  prohibiting the investment manager, or any subadviser, from considering sales
  of shares of the Fund as a factor in the selection of broker-dealers through
  which to execute securities transactions.

COMPARISON OF FUNDAMENTAL POLICIES

The Selling Fund and the Buying Fund have similar fundamental policies. The
Selling Fund, however, will not buy or sell physical commodities unless acquired
as a result of ownership of securities or other instruments, except this shall
not prevent the Selling Fund from buying or selling options and futures
contracts or from investing in securities or other instruments backed by, or
whose value is derived from, physical commodities. The Buying Fund has a similar
policy, except that the policy also does not extend to entering into forward
currency contracts.

If shareholders of the Selling Fund approve the Reorganization, they will be
subject to the fundamental policies of the Buying Fund.

The remaining fundamental policies of the Funds are identical. Each of the Funds
will not:

- - Act as an underwriter (sell securities for others). However, under the
  securities laws, the Fund may be deemed to be an underwriter when it purchases
  securities directly from the issuer and later resells them.

- - Lend securities or participate in an interfund lending program if the total of
  all such loans would exceed 33 1/3% of the Fund's total assets except this
  fundamental investment policy shall not prohibit the Fund from purchasing
  money market securities, loans, loan participation or other debt securities,
  or from entering into repurchase agreements.

- - Borrow money, except for temporary purposes (not for leveraging or investment)
  in an amount not exceeding 33 1/3% of its total assets (including the amount
  borrowed) less liabilities (other than borrowings) immediately after the
  borrowings.

- - Buy or sell real estate, unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  investing in securities or other instruments backed by real estate or
  securities of companies engaged in the real estate business or real estate
  investment trusts. For purposes of this policy, real estate includes real
  estate limited partnerships.

- - Issue senior securities, except as permitted under the 1940 Act.

- - Purchase more than 10% of the outstanding voting securities of an issuer,
  except that up to 25% of the Fund's assets may be invested without regard to
  this 10% limitation.

- - Invest more than 5% of its total assets in securities of any company,
  government, or political subdivision thereof, except the limitation will not
  apply to investments in securities issued or guaranteed by the U.S.
  government, its agencies, or instrumentalities, or other investment companies,
  and except that up to 25% of the Fund's total assets may be invested without
  regard to this 5% limitation.

- - Concentrate in any one industry. According to the present interpretation by
  the Securities and Exchange Commission (SEC), this means that up to 25% of the
  Fund's total assets, based on current market value at time of purchase, can be
  invested in any one industry.

COMPARISON OF NONFUNDAMENTAL POLICIES

Both Funds are also subject to the following nonfundamental policy:

- - No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

COMPARISON OF PRINCIPAL RISK FACTORS

The Selling Fund and the Buying Fund are subject to identical principal risks.

The principal risks of investing in each of the Selling Fund and the Buying Fund
are shown below:

 Quantitative Model Risk                                              X                      X
</Table>

- - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers to select
  securities and to make investment decisions that are suited to achieving the
  Fund's investment objective. Due to its active management, the Fund could
  underperform other mutual funds with similar investment objectives.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  counterparty credit risk, leverage risk, hedging risk, correlation risk and
  liquidity risk. Counterparty credit risk is the risk that a counterparty to
  the derivative instrument becomes bankrupt or otherwise fails to perform its
  obligations due to financial difficulties, and the Fund may obtain no recovery
  of its investment or may only obtain a limited recovery, and any recovery may
  be delayed. Hedging risk is the risk that derivative instruments used to hedge
  against an opposite position may offset losses, but they may also offset
  gains. Correlation risk is related to hedging risk and is the risk that there
  may be an incomplete correlation between the hedge and the opposite position,
  which may result in increased or unanticipated losses. Liquidity risk is the
  risk that the derivative instrument may be difficult or impossible to sell or
  terminate, which may cause the Fund to be in a position to do something the
  investment manager would not otherwise choose, including, accepting a lower
  price for the derivative instrument, selling other investments or foregoing
  another, more appealing investment opportunity. Leverage risk is the risk that
  losses from the derivative instrument may be greater than the amount invested
  in the derivative instrument. Certain derivatives have the potential for
  unlimited losses, regardless of the size of the initial investment. See the
  Merger SAI for more information on derivative instruments and related risks.

- - FOREIGN/EMERGING MARKETS RISK. The following are all components of
  foreign/emerging markets risk:

  Country risk includes the political, economic, and other conditions of the
  country. These conditions include lack of publicly available information, less
  government oversight (including lack of accounting, auditing, and financial
  reporting standards), the possibility of government-imposed restrictions, and
  even the nationalization of assets. The liquidity of foreign investments may
  be more limited than for most U.S. investments, which means that, at times it
  may be difficult to sell foreign securities at desirable prices.

  Currency risk results from the constantly changing exchange rate between local
  currency and the U.S. dollar. Whenever the Fund holds securities valued in a
  foreign currency or holds the currency, changes in the exchange rate add to or
  subtract from the value of the investment.

  Custody risk refers to the process of clearing and settling trades. It also
  covers holding securities with local agents and depositories. Low trading
  volumes and volatile prices in less developed markets make trades harder to
  complete and settle. Local agents are held only to the standard of care of the
  local market. Governments or trade groups may compel local agents to hold
  securities in designated depositories that are not subject to independent
  evaluation. The less developed a country's securities market is, the greater
  the likelihood of problems occurring.

  Emerging markets risk includes the dramatic pace of change (economic, social,
  and political) in these countries as well as the other considerations listed
  above. These markets are in early stages of development and are extremely
  volatile. They can be marked by extreme inflation, devaluation of currencies,
  dependence on trade partners, and hostile relations with neighboring
  countries.

- - ISSUER RISK. An issuer may perform poorly, and therefore, the value of its
  stocks and bonds may decline. Poor performance may be caused by poor
  management decisions, competitive pressures, breakthroughs in technology,
  reliance on suppliers, labor problems or shortages, corporate restructurings,
  fraudulent disclosures, or other factors.

 42 RIVERSOURCE FUNDS -- PROXY STATEMENT


- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably. This risk is generally greater for small and
  mid-sized companies, which tend to be more vulnerable to adverse developments.
  In addition, focus on a particular style, for example, investment in growth or
  value securities, may cause the Fund to underperform other mutual funds if
  that style falls out of favor with the market.

- - QUANTITATIVE MODEL RISK. Securities selected using quantitative methods may
  perform differently from the market as a whole for many reasons, including the
  factors used in building the quantitative analytical framework, the weights
  placed on each factor, and changing sources of market returns, among others.
  There can be no assurance that the methodology will enable the Fund to achieve
  its objective.

PERFORMANCE

Because Disciplined International Equity Fund commenced operations on May 18,
2006, no calendar year performance is available. The following bar chart and
table provide some illustration of the risks of investing in International
Equity Fund by showing, respectively:

- - how International Equity Fund's performance has varied for each full calendar
  year shown on the bar chart; and

- - how International Equity Fund's average annual total returns compare to
  recognized indexes shown on the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How International Equity Fund has
performed in the past (before and after taxes) does not indicate how
International Equity Fund will perform in the future. Performance reflects any
fee waivers/expense caps in effect for the periods reported. In the absence of
such fee waivers/expense caps, performance would have been lower.

Bar Chart. Class A share information is shown in the bar chart; the sales charge
for Class A shares is not reflected in the bar chart.

Table. The table shows total returns from hypothetical investments in Class A,
Class B, Class C, Class I and Class R4 shares of International Equity Fund.
These returns are compared to the indexes shown for the same periods. For
purposes of the performance calculation in the table we assumed:

- - the maximum sales charge for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge (CDSC) for Class B and Class C shares;

- - no sales charge for Class I and R4 shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 43


AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

PROPOSALS 4, 5 AND 6. REORGANIZATIONS OF EACH OF MASSACHUSETTS TAX-EXEMPT FUND,
MICHIGAN TAX-EXEMPT FUND AND OHIO TAX-EXEMPT FUND INTO TAX-EXEMPT HIGH INCOME
FUND

COMPARISON OF THE SELLING FUNDS AND THE BUYING FUND

The Selling Funds and the Buying Fund each:

- - Have RiverSource Investments as an investment adviser.

- - Have the same policies for buying and selling shares and the same exchange
  rights.

- - Have the same distribution policies.

- - Offer the same classes of shares: Classes A, B and C

- - Are structured as series of an open-end management investment company
  registered under the 1940 Act. The Buying Fund is a series of a Minnesota
  corporation, whereas the Selling Funds are each a series of a Massachusetts
  business trust. Please see Exhibit D to this proxy statement/prospectus for
  more information regarding the differences between the rights of shareholders
  of the Buying Fund and shareholders of the Selling Fund.

COMPARISON OF INVESTMENT OBJECTIVES

The investment objectives for the Funds are as follows:

        SELLING FUNDS: Each Selling Fund seeks to provide shareholders with a
                       high level of income generally exempt from federal income
                       tax as well as from the respective state and local income
                       tax.

        BUYING FUND: Tax-Exempt High Income Fund seeks to provide shareholders
                     with a high yield generally exempt from federal income
                     taxes.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

The Selling Funds and the Buying Fund have similar principal investment
strategies, except for the items noted below. First, whereas the Selling Funds
seek to provide income exempt from federal income taxes, as well as state and
local taxes, the Buying Fund seeks only to provide income exempt from federal
income taxes. In pursuit of their respective investment objectives, each of the
Funds normally invests at least 80% of its assets in municipal obligations.
However, as noted, because the Buying Fund does not seek to provide income
exempt from state and local taxes, it may invest in a broader geographic range
of the municipal securities market. Second, the Buying Fund is a "diversified"
fund, while each Selling Fund is a "non-diversified" fund, which means that a
Selling Fund can invest more of its assets in the securities of fewer issuers.
Third, whereas each Selling Fund may invest only up to 25% of its net assets in
lower-quality bonds (junk bonds), the Buying Fund is not subject to such a
limitation.

Despite these differences, each of the Selling Funds and the Buying Fund target
an average portfolio duration within one year of the duration of the primary
index against which it measures performance, which for the Selling Funds are:
the Lehman Brothers Massachusetts 3 Plus Year Enhanced Municipal Bond Index, the
Lehman Brothers Michigan Municipal Bond Index and the Lehman Brothers Ohio 4
Plus Year Enhanced Municipal Bond Index for Massachusetts Tax-Exempt Fund,
Michigan Tax-Exempt Fund and Ohio Tax-Exempt Fund, respectively, and for the
Buying Fund is the Lehman Brothers 3 Plus Year Municipal Bond Index.
Furthermore, the Selling Funds and the Buying Fund may each invest up to 20% of
its net assets in debt obligations whose interest is subject to federal
alternative minimum tax.

Detailed strategies for the Selling Funds and the Buying Fund are set forth
below:

MASSACHUSETTS TAX-EXEMPT FUND, MICHIGAN TAX-EXEMPT FUND AND OHIO TAX-EXEMPT FUND
(EACH A SELLING FUND):

Each Selling Fund is a non-diversified mutual fund. Under normal market
conditions, each Selling Fund invests at least 80% of its net assets in
municipal obligations that are generally exempt from federal income tax as well
as from the respective state and local income tax. Each Selling Fund may invest
more than 25% of its total assets in a particular segment of the municipal
securities market or in industrial revenue bonds. Each Selling Fund also may
invest up to 20% of its net assets in debt obligations whose interest is subject
to the alternative minimum tax computation. Additionally, each Selling Fund may
invest up to 25% of its net assets in lower-quality bonds (junk bonds).

In pursuit of each Selling Fund's objective, the investment manager chooses
investments by:

- - Considering opportunities and risks given current and expected interest rates.

- - Targeting an average portfolio duration within one year of the duration of the
  index against which the Fund measures its performance. Duration measures the
  sensitivity of bond prices to changes in interest rates. The longer the
  duration of a bond, the longer it will take to repay the principal and
  interest obligations and the more sensitive it will be to changes in interest
  rates. For example, a three-year duration means a bond is expected to decrease
  in value by 3% if interest rates rise 1% and increase in value by 3% if
  interest rates fall 1%.
- - Identifying obligations in sectors which, due to supply and demand, are
  offering higher yields than comparable instruments.

 46 RIVERSOURCE FUNDS -- PROXY STATEMENT


- - Identifying obligations that:

       - are investment-grade,

       - have coupons and/or maturities that are consistent with the investment
         manager's interest rate outlook, and

       - are expected to outperform other securities on a risk-adjusted basis
         (i.e., after considering coupon, sinking fund provision, call
         protection, and quality).

- - The terms of a municipal security determine the issuer.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- - The security is overvalued relative to alternative investments.

- - The issuer's credit rating declines or the investment manager expects a
  decline (the Massachusetts Tax-Exempt Fund may continue to own securities that
  are downgraded until the investment manager believes it is advantageous to
  sell).

- - Political, economic, or other events could affect the issuer's performance.

- - The investment manager expects the issuer to call the security.

- - The investment manager identifies a more attractive opportunity.

The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, structured notes, including
inverse floaters, in an effort to produce incremental earnings, to hedge
existing positions, to increase market exposure and investment flexibility, or
to obtain or reduce credit exposure.

TAX-EXEMPT HIGH INCOME FUND (BUYING FUND):

Under normal market conditions, Tax-Exempt High Income Fund will invest at least
80% of its net assets in municipal bonds and in other debt obligations issued by
or on behalf of state or local governmental units whose interest is exempt from
federal income tax and is not subject to the alternative minimum tax (AMT).
However, Tax-Exempt High Income Fund may invest up to 20% of its net assets in
debt obligations the interest from which is subject to AMT. Tax-Exempt High
Income Fund invests its assets in medium and higher quality municipal bonds and
other debt obligations. Tax-Exempt High Income Fund may also invest in
lower-quality bonds which help to obtain a higher portfolio yield. Lower-quality
bonds, often called "junk bonds" include securities that are rated below
investment grade, commonly defined as bonds receiving a Standard & Poor's rating
below BBB or a Moody's rating below Baa or non-rated securities of comparable
quality.

In pursuit of Tax-Exempt High Income Fund's objective, the Fund's investment
manager chooses investments by:

- - Considering opportunities and risks in municipal obligations given current and
  expected interest rates.

- - Targeting an average portfolio duration within one year of the duration of the
  Lehman Brothers 3 Plus Year Municipal Bond Index. Duration measures the
  sensitivity of bond prices to changes in interest rates. The longer the
  duration of a bond, the longer it will take to pay the principal and interest
  on the bond and the more sensitive it will be to changes in interest rates.

For example, a five-year duration means a bond is expected to decrease in value
by 5% if interest rates rise 1% and increase in value by 5% if interest rates
fall 1%.

- - Identifying municipal obligations that it believes:

       - range from high to lower credit quality, including non-rated
         securities;

       - have maturities that represent the full spectrum of the municipal yield
         curve;

       - represent strong relative value; and

       - have characteristics (coupon, call, maturity, etc.) that fit Tax-Exempt
         High Income Fund's investment strategy at the time of purchase.

- - Seeking to identify investments that contribute to portfolio diversification.
  The investment manager attempts to modify relative exposure to certain
  credits, sectors, maturities, states, or bond structures based on the
  investment manager's opinion of relative value and expected market trends.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- - The security is overvalued relative to alternative investments.

- - The issuer's credit rating declines or the investment manager expects a
  decline in the issuer's creditworthiness (the Fund may continue to own
  securities that are downgraded until the investment manager believes it is
  advantageous to sell).

- - Political, economic, or other events could negatively affect the issuer's
  performance.
- - The investment manager expects the issuer to call the security.

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 47


- - The investment manager identifies a more attractive investment opportunity.

- - The issuer or the security continues to meet the security selection criteria
  described above.

The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, structured notes, including
inverse floaters, in an effort to produce incremental earnings, to hedge
existing positions, to increase market exposure and investment flexibility, or
to obtain or reduce credit exposure.

EACH OF THE SELLING FUNDS AND THE BUYING FUND:

- - Other Investment Strategies. In addition to the principal investment
  strategies previously described, the Fund may utilize investment strategies
  that are not principal investment strategies, including investment in
  affiliated and non-affiliated pooled investment vehicles (including mutual
  funds and exchange traded funds (ETFs), also referred to as "acquired funds")
  ownership of which results in the Fund bearing its proportionate share of the
  acquired funds' fees and expenses. Although ETFs are designed to replicate the
  price and yield of a specified market index, there is no guarantee that an ETF
  will track its specified market index, which may result in a loss. For more
  information on strategies and holdings, and the risks of such strategies,
  including derivative instruments that the Buying Fund may use, see the Fund's
  Merger SAI and the Fund's annual and semiannual reports.

- - Unusual Market Conditions. During unusual market conditions, the Fund may
  temporarily invest more of its assets in money market securities than during
  normal market conditions. Although investing in these securities would serve
  primarily to attempt to avoid losses, this type of investing also could
  prevent the Fund from achieving its investment objective. During these times,
  the portfolio managers may make frequent securities trades that could result
  in increased fees, expenses and taxes, and decreased performance.

- - Portfolio Turnover. Trading of securities may produce capital gains, which are
  taxable to shareholders when distributed. Active trading may also increase the
  amount of brokerage commissions paid or mark-ups to broker-dealers that the
  Fund pays when it buys and sells securities. Capital gains and increased
  brokerage commissions or mark-ups paid to broker-dealers may adversely affect
  a Fund's performance. The Buying Fund's historical portfolio turnover rate,
  which measures how frequently the Buying Fund buys and sells investments, is
  shown in Section D -- "Financial Highlights."

- - Securities Transaction Commissions. Securities transactions involve the
  payment by the Fund of brokerage commissions to broker-dealers, on occasion as
  compensation for research or brokerage services (commonly referred to as "soft
  dollars"), as the portfolio managers buy and sell securities for the Fund in
  pursuit of its objective. A description of the policies governing the Buying
  Fund's securities transactions and the dollar value of brokerage commissions
  paid by the Buying Fund is set forth in the Merger SAI. Funds that invest
  primarily in fixed income securities do not typically generate brokerage
  commissions that are used to pay for research or brokerage services. The
  brokerage commissions set forth in the SAI do not include implied commissions
  or mark-ups (implied commissions) paid by the Buying Fund for principal
  transactions (transactions made directly with a dealer or other counterparty),
  including most fixed income securities (and certain other instruments,
  including derivatives). Brokerage commissions do not reflect other elements of
  transaction costs, including the extent to which the Fund's purchase and sale
  transactions may cause the market to move and change the market price for an
  investment.

  Although brokerage commissions and implied commissions are not reflected in
  the expense table under "Fees and Expenses," they are reflected in the total
  return of the Fund.

- - Directed Brokerage. The Fund's Board of Directors (Board) has adopted a policy
  prohibiting the investment manager, or any subadviser, from considering sales
  of shares of the Fund as a factor in the selection of broker-dealers through
  which to execute securities transactions.

COMPARISON OF FUNDAMENTAL POLICIES

The Selling Funds and the Buying Fund have similar fundamental policies, except
for the items noted below. First, whereas the Buying Fund has a policy that it
will not, under normal market conditions, invest less than 80% of its net assets
in bonds and notes issued by or on behalf of state and local governmental units
whose interest, in the opinion of counsel for the issuer, is exempt from federal
income tax and is not subject to the alternative minimum tax, the Selling Funds
will not under normal market conditions, invest less than 80% of its net assets
in municipal obligations that are generally exempt from federal income tax as
well as the respective state and local income tax. Second, the Selling Fund, as
a "non-diversified fund" may invest more of its assets in the securities of
fewer issuers.

If shareholders of a Selling Fund approve the Reorganization, they will be
subject to the fundamental policies of the Buying Fund.

The other fundamental policies of the Funds are set forth below. Each of the
Funds will not:

- - Act as an underwriter (sell securities for others). However, under the
  securities laws, the Fund may be deemed to be an underwriter when it purchases
  securities directly from the issuer and later resells them.

 48 RIVERSOURCE FUNDS -- PROXY STATEMENT


- - Lend securities or participate in an interfund lending program if the total of
  all such loans would exceed 33 1/3% of the Fund's total assets, except this
  fundamental investment policy shall not prohibit the Fund from purchasing
  money market securities, loans, loan participation or other debt securities,
  or from entering into repurchase agreements.

- - Borrow money, except for temporary purposes (not for leveraging or investment)
  in an amount not exceeding 33 1/3% of its total assets (including the amount
  borrowed) less liabilities (other than borrowings) immediately after the
  borrowings.

- - Buy or sell real estate, unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  investing in securities or other instruments backed by real estate or
  securities of companies engaged in the real estate business or real estate
  investment trusts. For purposes of this policy, real estate includes real
  estate limited partnerships.

- - Buy or sell physical commodities unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  buying or selling options and futures contracts or from investing in
  securities or other instruments backed by, or whose value is derived from,
  physical commodities.

In addition, neither Fund may issue senior securities, except as permitted under
the 1940 Act.

As a "diversified fund," the Buying Fund is subject to the following additional
fundamental investment policies:

- - The Fund will not purchase more than 10% of the outstanding voting securities
  of an issuer, except that up to 25% of the Fund's assets may be invested
  without regard to this 10% limitation. For tax-exempt funds, for purposes of
  this policy, the terms of a municipal security determine the issuer.

- - The Fund will not invest more than 5% of its total assets in securities of any
  company, government, or political subdivision thereof, except the limitation
  will not apply to investments in securities issued or guaranteed by the U.S.
  government, its agencies, or instrumentalities, or other investment companies,
  and except that up to 25% of the Fund's total assets may be invested without
  regard to this 5% limitation. For tax-exempt funds, for purposes of this
  policy, the terms of a municipal security determine the issuer.

COMPARISON OF NONFUNDAMENTAL POLICIES

Both Funds are also subject to the following nonfundamental policy:

- - No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

COMPARISON OF PRINCIPAL RISK FACTORS

Each of the Selling Funds and the Buying Fund are subject to similar principal
risks. The Selling Funds are subject to the additional principal risks related
to diversification and geographic concentration because each Selling Fund
focuses its investments within a specific geographic region (state) and each is
a "non-diversified" fund.

The principal risks of investing in each of the Selling Funds and the Buying
Fund are shown below:

</Table>

- - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers to select
  securities and to make investment decisions that are suited to achieving the
  Fund's investment objective. Due to its active management, the Fund could
  underperform other mutual funds with similar investment objectives.

- - CREDIT RISK. Credit risk is the risk that the issuer of a security, or the
  counterparty to a contract, will default or otherwise become unable or
  unwilling to honor a financial obligation, such as payments due on a bond or a
  note. If the Fund purchases unrated securities, or if the rating of a security
  is reduced after purchase, the Fund will depend on the investment manager's
  analysis of credit risk more heavily than usual. Non-investment grade
  securities, commonly called "high-yield" or "junk" bonds, may react more to
  perceived changes in the ability of the issuing entity to pay interest and
  principal when due than to changes in interest rates. Non-investment grade
  securities have greater price fluctuations and are more likely to experience a
  default than investment grade bonds.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 49


  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  counterparty credit risk, leverage risk, hedging risk, correlation risk and
  liquidity risk. Counterparty credit risk is the risk that a counterparty to
  the derivative instrument becomes bankrupt or otherwise fails to perform its
  obligations due to financial difficulties, and the Fund may obtain no recovery
  of its investment or may only obtain a limited recovery, and any recovery may
  be delayed. Hedging risk is the risk that derivative instruments used to hedge
  against an opposite position may offset losses, but they may also offset
  gains. Correlation risk is related to hedging risk and is the risk that there
  may be an incomplete correlation between the hedge and the opposite position,
  which may result in increased or unanticipated losses. Liquidity risk is the
  risk that the derivative instrument may be difficult or impossible to sell or
  terminate, which may cause the Fund to be in a position to do something the
  investment manager would not otherwise choose, including, accepting a lower
  price for the derivative instrument, selling other investments or foregoing
  another, more appealing investment opportunity. Leverage risk is the risk that
  losses from the derivative instrument may be greater than the amount invested
  in the derivative instrument. Certain derivatives have the potential for
  unlimited losses, regardless of the size of the initial investment. See the
  Merger SAI for more information on derivative instruments and related risks.

- - DIVERSIFICATION RISK. A non-diversified Fund may invest more of its assets in
  fewer companies than if it were a diversified fund. Because each investment
  has a greater effect on the Fund's performance, the Fund may be more exposed
  to the risks of loss and volatility then a Fund that invests more broadly.

- - GEOGRAPHIC CONCENTRATION RISK. Because state-specific tax-exempt funds invest
  primarily in the municipal securities issued by the state and political
  sub-divisions of the state, each Fund will be particularly affected by
  political and economic conditions and developments in the state in which it
  invests. This vulnerability to factors affecting the state's tax-exempt
  investments will be significantly greater than that of a more geographically
  diversified fund, which may result in greater losses and volatility. See the
  Merger SAI for details. The value of municipal securities owned by a Fund also
  may be adversely affected by future changes in federal or state income tax
  laws.

  In addition, because of the relatively small number of issuers of tax-exempt
  securities, the Fund may invest a higher percentage of assets in a single
  issuer and, therefore, be more exposed to the risk of loss by investing in a
  few issuers than a Fund that invests more broadly. At times, the Fund and
  other accounts managed by investment manager may own all or most of the debt
  of a particular issuer. This concentration of ownership may make it more
  difficult to sell, or to determine the fair value of, these investments.

- - INTEREST RATE RISK. Interest rate risk is the risk of losses attributable to
  changes in interest rates. Interest rate risk is generally associated with
  bond prices: when interest rates rise, bond prices fall. In general, the
  longer the maturity or duration of a bond, the greater its sensitivity to
  changes in interest rates.

- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably.

- - PREPAYMENT AND EXTENSION RISK. Prepayment and extension risk is the risk that
  a bond or other security might be called or otherwise converted, prepaid, or
  redeemed before maturity. This risk is primarily associated with asset-backed
  securities, including mortgage-backed securities. If a security is converted,
  prepaid, or redeemed before maturity, particularly during a time of declining
  interest rates, the investment manager may not be able to reinvest in
  securities providing as high a level of income, resulting in a reduced yield
  to the Fund. Conversely, as interest rates rise, the likelihood of prepayment
  decreases. The investment manager may be unable to capitalize on securities
  with higher interest rates because the Fund's investments are locked in at a
  lower rate for a longer period of time.

PERFORMANCE

The following bar chart and table provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how a Fund's performance has varied for each full calendar year shown on the
  bar chart; and

- - how a Fund's average annual total returns compare to recognized indexes shown
  on the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Chart. Class A share information is shown in the bar chart; the sales charge
for Class A shares is not reflected in the bar chart.

 50 RIVERSOURCE FUNDS -- PROXY STATEMENT


Table. The table shows total returns from hypothetical investments in Class A,
Class B and Class C shares of the Fund. These returns are compared to the
indexes shown for the same periods. For purposes of the performance calculation
in the table we assumed:

- - the maximum sales charge for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge (CDSC) for Class B and Class C shares; and

- - no adjustments for taxes paid by an investor on the reinvested income and
  capital gains.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

PROPOSAL 7. REORGANIZATION OF VALUE FUND INTO DIVERSIFIED EQUITY INCOME FUND

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

- - Have RiverSource Investments as an investment adviser.

- - Have the same policies for buying and selling shares and the same exchange
  rights.

- - Have the same distribution policies.

- - Offer Classes A, B, C, I and R4 (the Buying Fund also offers Classes R2, R3,
  R5 and W).

- - Are structured as a series of capital stock of an open-end management
  investment company organized as a Minnesota corporation.

COMPARISON OF INVESTMENT OBJECTIVES

The investment objectives for the Funds are similar. Whereas the Selling Fund
seeks to provide shareholders with long-term capital growth as a primary
objective, this is a secondary objective of the Buying Fund, and whereas the
Buying Fund seeks to provide a high level of current income, income is a
secondary objective of the Selling Fund. This difference has not materially
affected the way that the Funds have been managed.

        SELLING FUND: Value Fund seeks to provide shareholders with long-term
                      capital growth. Income is a secondary objective.

        BUYING FUND: Diversified Equity Income Fund seeks to provide
                     shareholders with a high level of current income and, as a
                     secondary objective, steady growth of capital.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

The Buying Fund will invest at least 80% of its net assets in dividend-paying
common and preferred stocks. Each Fund may invest up to 25% of its net assets in
foreign investments. The Selling Fund invests primarily in securities of large,
well established U.S. and multinational companies. Although RiverSource
Investments serves as investment manager of both Funds, the Selling Fund was,
until Nov. 16, 2007, sub-advised by Lord, Abbett & Co. LLC (Lord Abbett). The
Selling Fund's Board of Directors terminated the contract of Lord Abbett. Since
Nov. 16, 2007, RiverSource Investments has solely managed the Selling Fund.
Detailed strategies for the Selling Fund and the Buying Fund are set forth
below:

VALUE FUND (SELLING FUND):

Value Fund's assets primarily are invested in equity securities. This Fund may
invest up to 25% of its net assets in foreign investments. The Fund can invest
in any economic sector and, at times, it may emphasize one or more particular
sectors.

In pursuit of Value Fund's objectives, the investment manager chooses equity
investments by seeking to:

- - Identify stocks that are selling at low prices in relation to:

       - current and projected earnings;

       - current and projected dividends; and

       - historic price levels.

- - Identify companies with moderate growth potential based on:

       - effective management, as demonstrated by overall performance; and

       - financial strength.

- - Identify companies with dividend-paying stocks.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- - The security is overvalued relative to alternative investments.

- - The security has reached the investment manager's price objective.

- - The company has met the investment manager's earnings and/or growth
  expectations.

- - The company or the security continues to meet the other standards described
  above.

DIVERSIFIED EQUITY INCOME FUND (BUYING FUND):

Diversified Equity Income Fund's assets primarily are invested in equity
securities. Under normal market conditions, the Fund will invest at least 80% of
its net assets in dividend-paying common and preferred stocks. This Fund may
invest up to 25% of its net assets in foreign investments. The Fund can 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' notice of any
change in the 80% policy.

 56 RIVERSOURCE FUNDS -- PROXY STATEMENT


In pursuit of Diversified Equity Income Fund's objectives, the investment
manager chooses equity investments by seeking to:

- - Identify stocks that are selling at low prices in relation to:

       - current and projected earnings;

       - current and projected dividends; and

       - historic price levels.

- - Identify companies with moderate growth potential based on:

       - effective management, as demonstrated by overall performance; and

       - financial strength.

- - Identify companies with dividend-paying stocks.

In evaluating whether to sell a security, the investment manager considers,
among other factors, whether:

- - The security is overvalued relative to alternative investments.

- - The security has reached the investment manager's price objective.

- - The company has met the investment manager's earnings and/or growth
  expectations.

- - The company or the security continues to meet the other standards described
  above.

BOTH FUNDS:

- - Other Investment Strategies. In addition to the principal investment
  strategies previously described, the Fund may utilize investment strategies
  that are not principal investment strategies, including investment in
  affiliated and non-affiliated pooled investment vehicles (including mutual
  funds and exchange traded funds (ETFs), also referred to as "acquired funds")
  ownership of which results in the Fund bearing its proportionate share of the
  acquired funds' fees and expenses. Although ETFs are designed to replicate the
  price and yield of a specified market index, there is no guarantee that an ETF
  will track its specified market index, which may result in a loss.
  Additionally, the Fund may use derivatives such as futures, options, forward
  contracts, and swaps (which are financial instruments that have a value which
  depends upon, or is derived from, the value of something else, such as one or
  more underlying securities, pools of securities, indexes or currencies). These
  derivative instruments are used to produce incremental earnings, to hedge
  existing positions, to increase or reduce market or credit exposure, or to
  increase flexibility. Derivative instruments will typically increase the
  Fund's exposure to the principal risks to which it is otherwise exposed, and
  may expose the Fund to additional risks, including counterparty credit risk,
  leverage risk, hedging risk, correlation risk and liquidity risk. Counterparty
  credit risk is the risk that a counterparty to the derivative instrument
  becomes bankrupt or otherwise fails to perform its obligations due to
  financial difficulties, and the Fund may obtain no recovery of its investment
  or may only obtain a limited recovery, and any recovery may be delayed.
  Hedging risk is the risk that derivative instruments used to hedge against an
  opposite position may offset losses, but they may also offset gains.
  Correlation risk is related to hedging risk and is the risk that there may be
  an incomplete correlation between the hedge and the opposite position, which
  may result in increased or unanticipated losses. Liquidity risk is the risk
  that the derivative instrument may be difficult or impossible to sell or
  terminate, which may cause the Fund to be in a position to do something the
  investment manager or subadviser would not otherwise choose, including,
  accepting a lower price for the derivative instrument, selling other
  investments, or foregoing another, more appealing investment opportunity.
  Leverage risk is the risk that losses from the derivative instrument may be
  greater than the amount invested in the derivative instrument. In addition, a
  relatively small price movement in the underlying security, currency or index
  may result in a substantial gain or loss for the Fund using derivatives and
  certain derivatives have the potential for unlimited losses, regardless of the
  size of the initial investment. Even though the Fund's policies permit the use
  of derivatives in this manner, the portfolio managers are not required to use
  derivatives. For more information on strategies and holdings, and the risks of
  such strategies, including derivative instruments that the Buying Fund may
  use, see the Merger SAI.

- - Unusual Market Conditions. During unusual market conditions, the Fund may
  temporarily invest more of its assets in money market securities than during
  normal market conditions. Although investing in these securities would serve
  primarily to attempt to avoid losses, this type of investing also could
  prevent the Fund from achieving its investment objective. During these times,
  the portfolio managers may make frequent securities trades that could result
  in increased fees, expenses and taxes, and decreased performance. Instead of
  investing in money market securities directly, the Fund may invest in shares
  of an affiliated money market fund.

- - Securities Transaction Commissions. Securities transactions involve the
  payment by the Fund of brokerage commissions to broker-dealers, on occasion as
  compensation for research or brokerage services (commonly referred to as "soft
  dollars"), as the portfolio managers buy and sell securities for the Fund in
  pursuit of its objective. A description of the policies governing the Buying
  Fund's securities transactions and the dollar value of brokerage commissions
  paid by the Buying Fund is set forth

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 57


  in the Merger SAI. The brokerage commissions set forth in the Merger SAI do
  not include implied commissions or mark-ups (implied commissions) paid by the
  Buying Fund for principal transactions (transactions made directly with a
  dealer or other counterparty), including most fixed income securities (and
  certain other instruments, including derivatives). Brokerage commissions do
  not reflect other elements of transaction costs, including the extent to which
  the Fund's purchase and sale transactions may cause the market to move and
  change the market price for an investment.

  Although brokerage commissions and implied commissions are not reflected in
  the expense table under "Fees and Expenses," they are reflected in the total
  return of the Fund.

- - Portfolio Turnover. Trading of securities may produce capital gains, which are
  taxable to shareholders when distributed. Active trading may also increase the
  amount of brokerage commissions paid or mark-ups to broker-dealers that the
  Fund pays when it buys and sells securities. For subadvised funds, a change in
  a subadviser may result in increased portfolio turnover, which increase may be
  substantial, as the new subadviser realigns the portfolio, or if the
  subadviser(s) trades portfolio securities more frequently. A realignment or
  more active strategy could produce higher than expected capital gains. Capital
  gains and increased brokerage commissions or mark-ups paid to broker-dealers
  may adversely affect a Fund's performance. The Buying Fund's historical
  portfolio turnover rate, which measures how frequently the Buying Fund buys
  and sells investments, is shown in Section C -- "Financial Highlights."

- - Directed Brokerage. The Fund's Board of Directors (Board) has adopted a policy
  prohibiting the investment manager, or any subadviser, from considering sales
  of shares of the Fund as a factor in the selection of broker-dealers through
  which to execute securities transactions.

COMPARISON OF FUNDAMENTAL POLICIES

The Selling Fund and the Buying Fund have substantially similar fundamental
investment policies. The investment manager does not believe that the
differences between the fundamental investment policies will result in any
material difference in the way the Funds are managed.

If shareholders of the Selling Fund approve the Reorganization, they will be
subject to the fundamental investment policies of the Buying Fund.

The fundamental policies of the Funds are set forth below. Neither of the Funds
will:

- - Act as an underwriter (sell securities for others). However, under the
  securities laws, the Fund may be deemed to be an underwriter when it purchases
  securities directly from the issuer and later resells them.

- - Lend securities or participate in an interfund lending program if the total of
  all such loans would exceed 33 1/3% of the Fund's total assets except this
  fundamental investment policy shall not prohibit the Fund from purchasing
  money market securities, loans, loan participation or other debt securities,
  or from entering into repurchase agreements.

- - Borrow money, except for temporary purposes (not for leveraging or investment)
  in an amount not exceeding 33 1/3% of its total assets (including the amount
  borrowed) less liabilities (other than borrowings) immediately after the
  borrowings.

- - Buy or sell real estate, unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  investing in securities or other instruments backed by real estate or
  securities of companies engaged in the real estate business or real estate
  investment trusts. For purposes of this policy, real estate includes real
  estate limited partnerships.

- - Buy or sell physical commodities unless acquired as a result of ownership of
  securities or other instruments, except this shall not prevent the Fund from
  buying or selling options and futures contracts or from investing in
  securities or other instruments backed by, or whose value is derived from,
  physical commodities.

- - Purchase more than 10% of the outstanding voting securities of an issuer,
  except that up to 25% of the Fund's assets may be invested without regard to
  this 10% limitation.

- - Invest more than 5% of its total assets in securities of any company,
  government, or political subdivision thereof, except the limitation will not
  apply to investments in securities issued or guaranteed by the U.S.
  government, its agencies, or instrumentalities, or other investment companies,
  and except that up to 25% of the Fund's total assets may be invested without
  regard to this 5% limitation.

- - Concentrate in any one industry. According to the present interpretation by
  the Securities and Exchange Commission (SEC), this means that up to 25% of the
  Fund's total assets, based on current market value at time of purchase, can be
  invested in any one industry.

In addition, neither Fund may issue senior securities, except as permitted under
the 1940 Act.

 58 RIVERSOURCE FUNDS -- PROXY STATEMENT


COMPARISON OF NONFUNDAMENTAL POLICIES

Both Funds are also subject to the following nonfundamental policies:

- - No more than 15% of the Fund's net assets will be held in securities and other
  instruments that are illiquid.

- - Up to 25% of the Buying fund's net assets may be invested in foreign
  investments.

COMPARISON OF PRINCIPAL RISK FACTORS

The Selling Fund and the Buying Fund are subject to identical principal risks.

- - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers to select
  securities and to make investment decisions that are suited to achieving the
  Fund's investment objectives. Due to its active management, the Fund could
  underperform other mutual funds with similar investment objectives.

- - FOREIGN RISK. The following are all components of foreign risk:

  Country risk includes the political, economic, and other conditions of a
  country. These conditions include lack of publicly available information, less
  government oversight (including lack of accounting, auditing, and financial
  reporting standards), the possibility of government-imposed restrictions, and
  even the nationalization of assets. The liquidity of foreign investments may
  be more limited than for most U.S. investments, which means that, at times, it
  may be difficult to sell foreign securities at desirable prices.

  Currency risk results from the constantly changing exchange rate between local
  currency and the U.S. dollar. Whenever the Fund holds securities valued in a
  foreign currency or holds the currency, changes in the exchange rate add or
  subtract from the value of the investment.

  Custody risk refers to the process of clearing and settling trades. It also
  covers holding securities with local agents and depositories. Low trading
  volumes and volatile prices in less developed markets make trades harder to
  complete and settle. Local agents are held only to the standard of care of the
  local market. Governments or trade groups may compel local agents to hold
  securities in designated depositories that are not subject to independent
  evaluation. The less developed a country's securities market is, the greater
  the likelihood of problems occurring.

- - ISSUER RISK. An issuer may perform poorly, and therefore, the value of its
  stocks and bonds may decline. Poor performance may be caused by poor
  management decisions, competitive pressures, breakthroughs in technology,
  reliance on suppliers, labor problems or shortages, corporate restructurings,
  fraudulent disclosures or other factors.

- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably. This risk is generally greater for small and
  mid-sized companies, which tend to be more vulnerable to adverse developments.
  In addition, focus on a particular style, for example, investment in growth or
  value securities, may cause the Fund to underperform other mutual funds if
  that style falls out of favor with the market.

- - SECTOR RISK. If a Fund emphasizes one or more economic sectors, it may be more
  susceptible to the financial, market or economic events affecting the
  particular issuers and industries in which it invests than funds that do not
  emphasize particular sectors. The more a Fund diversifies, the more it spreads
  risk and potentially reduces the risks of loss and volatility.

- - SMALL AND MID-SIZED COMPANY RISK. Investments in small and medium companies
  often involve greater risks than investments in larger, more established
  companies because small and medium companies may lack the management
  experience, financial resources, product diversification, experience, and
  competitive strengths of larger companies. Additionally, in many instances the
  securities of small and medium companies are traded only over-the-counter or
  on regional securities exchanges and the frequency and volume of their trading
  is substantially less and may be more volatile than is typical of larger
  companies.

PERFORMANCE

The following bar chart and table provide some illustration of the risks of
investing in the Fund by showing, respectively:

- - how the Fund's performance has varied for each full calendar year shown on the
  bar chart; and

- - how the Fund's average annual total returns compare to recognized indexes
  shown on the table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How the Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Chart. Class A share information is shown in the bar chart; the sales charge
for Class A shares is not reflected in the bar chart.

Table. The table shows total returns from hypothetical investments in Class A,
Class B, Class C, Class I, and Class R4 shares of the Fund. These returns are
compared to the indexes shown for the same periods. For purposes of the
performance calculation in the table we assumed:

- - the maximum sales charge for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge (CDSC) for Class B and Class C shares;

- - no sales charge for Class I and R4 shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

identical investment objective and investment strategies. As of Dec. 6, 2005,
the fund became a stand-alone fund that invests directly in a portfolio of
securities. The information shown in the table and in the financial highlights

 62 RIVERSOURCE FUNDS -- PROXY STATEMENT


ADDITIONAL INFORMATION ABOUT EACH REORGANIZATION

TERMS OF THE REORGANIZATIONS

The Board has approved the Agreement, a copy of which is attached as Exhibit A.
The Agreement provides for each Reorganization on the following terms:

- - The Reorganization is expected to occur in the first quarter of 2008, pending
  shareholder approval and receipt of any necessary regulatory approvals.
  However, following shareholder approval, the Reorganization may happen at any
  time as agreed to between the Selling Fund and the Buying Fund.

- - The Selling Fund will transfer all of its assets to the Buying Fund and, in
  exchange, the Buying Fund will assume all the Selling Fund's liabilities and
  will issue to the Selling Fund, as applicable, Class A, B, C, I, R2, R3, R4,
  R5 and W shares with an aggregate net asset value at the time of the
  Reorganization equal to the value of the assets of Classes A, B, C, I, R2, R3,
  R4, R5 and W shares that it receives from the Selling Fund, less the
  liabilities assumed by the Buying Fund in the transaction. These shares will
  immediately be distributed by the Selling Fund to its shareholders in
  proportion to their holdings in the Selling Fund. As a result, shareholders of
  the Selling Fund will become Class A, B, C, I, R2, R3, R4, R5 or W
  shareholders of the Buying Fund.

- - Neither the Selling Fund nor the shareholders of the Selling Fund will pay any
  sales charge in connection with the Reorganization.

- - The net asset value of the Selling Fund and the Buying Fund will be computed
  as of 3:00 p.m. Central time, on the business day immediately preceding the
  closing date.

- - After the Reorganization, the Selling Fund will be terminated.

CONDITIONS TO CLOSING EACH REORGANIZATION

The completion of each Reorganization is subject to certain conditions described
in the Agreement, including:

- - The Selling Fund will have declared and paid a dividend that will distribute
  all of the Fund's taxable income, if any, to the shareholders of the Fund for
  the taxable years ending at or prior to the closing.

- - The Funds will have received any approvals, consents or exemptions from the
  SEC or any regulatory body necessary to carry out the Reorganization.

- - A registration statement on Form N-14 will have been filed with the SEC and
  declared effective.

- - The shareholders of the Selling Fund will have approved the Agreement.

- - The Selling Fund will have received an opinion of tax counsel that, although
  not entirely free from doubt, the proposed Reorganization will not result in
  gain or loss to any shareholder for federal income tax purposes.

TERMINATION OF THE AGREEMENT

The Agreement and the transactions contemplated by it may be terminated and
abandoned with respect to any Reorganization by resolutions of the Board of the
Selling Fund or the Buying Fund at any time prior to closing. In the event of a
termination, there will be no liability for damages on the part of either the
Selling Fund or the Buying Fund or any of their affiliates.

TAX STATUS OF THE REORGANIZATIONS

Each Reorganization is expected to be tax-free for federal income tax purposes
and will not take place in any case unless the Selling Fund and the Buying Fund
receive a satisfactory opinion of tax counsel (which opinion will be based on
certain factual representations and certain customary assumptions), to the
effect that, although not entirely free from doubt, on the basis of existing
provisions of the Internal Revenue Code of 1986, as amended (the "Code", U.S.
Treasury regulations issued thereunder ("Regulations"), current administrative
rules, pronouncements and court decisions, for federal income tax purposes):

- - The transfer of the Selling Fund's assets to the Buying Fund in exchange for
  Class A, B, C, I, R2, R3, R4, R5 and W shares, as applicable, of the Buying
  Fund and the assumption of the Selling Fund's liabilities, followed by the
  distribution of those Class A, B, C, I, R2, R3, R4, R5 and W shares, as
  applicable, to the Selling Fund's shareholders and the termination of the
  Selling Fund will be a "reorganization" within the meaning of Section
  368(a)(1) of the Code, and the Selling Fund and the Buying Fund will each be a
  "party to the reorganization" within the meaning of Section 368(b) of the
  Code.

- - Under Section 361 of the Code, no gain or loss will be recognized by the
  Selling Fund upon the transfer of all of its assets to the Buying Fund or on
  the distribution by the Selling Fund of Class A, B, C, I, R2, R3, R4, R5 and W
  shares, as applicable, of the Buying Fund to Selling Fund shareholders in
  liquidation.

- - Under Section 354 of the Code, the shareholders of the Selling Fund will not
  recognize gain or loss upon the exchange of their Class A, B, C, I, R2, R3,
  R4, R5 and W shares, as applicable, of the Selling Fund solely for Buying Fund
  Class A, B, C, I, R2, R3, R4, R5 and W shares, as applicable, as part of the
  Reorganization.

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 63


- - Under Section 358 of the Code, the aggregate basis of the Class A, B, C, I,
  R2, R3, R4, R5 and W shares, as applicable, of the Buying Fund that a Selling
  Fund shareholder receives in the Reorganization will be the same as the
  aggregate basis of the Class A, B, C, I, R2, R3, R4, R5 and W shares, as
  applicable, of the Selling Fund exchanged therefor.

- - Under Section 1223(1) of the Code, the tax holding period for the Class A, B,
  C, I, R2, R3, R4, R5 and W shares, as applicable, of the Buying Fund that a
  Selling Fund shareholder receives in the Reorganization will include the
  period for which he or she held the Class A, B, C, I, R2, R3, R4, R5 and W
  shares, as applicable, of the Selling Fund exchanged therefor, provided that
  on the date of the exchange he or she held such Selling Fund shares as capital
  assets.

- - Under Section 1032 of the Code, no gain or loss will be recognized by the
  Buying Fund upon the receipt of the Selling Fund's assets solely in exchange
  for the issuance of Buying Fund's Class A, B, C, I, R2, R3, R4, R5 and W
  shares, as applicable, to the Selling Fund and the assumption of all of the
  Selling Fund's liabilities by the Buying Fund.

- - Under Section 362(b) of the Code, the Buying Fund's tax basis in the assets
  that the Buying Fund received from the Selling Fund will be the same as the
  Selling Fund's tax basis in those assets immediately prior to the transfer.

- - Under Section 1223(2) of the Code, the Buying Fund's holding periods in the
  assets received from the Selling Fund will include the Selling Fund's holding
  periods in such assets.

- - Under Section 381 of the Code, the Buying Fund will succeed to and take into
  account the items of the Selling Fund described in Section 381(c) of the Code,
  subject to the conditions and limitations specified in Sections 381, 382, 383
  and 384 of the Code and Regulations thereunder.

The opinion will note and distinguish certain published precedent; it is
possible that the Internal Revenue Service (the "IRS") could disagree with tax
counsel's opinion.

Tax counsel will express no view with respect to the effect of the
Reorganization on any transferred assets as to which any unrealized gain or loss
is required to be recognized at the end of a taxable year (or on the termination
or transfer thereof) under federal income tax principles.

A portion of the portfolio assets of the Selling Fund may be sold in connection
with the Reorganization. The actual tax impact of such sales will depend on the
difference between the price at which such portfolio assets are sold and the
Selling Fund's basis in such assets. Any net capital gains recognized in these
sales will be distributed to Selling Fund shareholders as capital gain dividends
(to the extent of net realized long-term capital gains) and/or ordinary
dividends (to the extent of net realized short-term capital gains) during or
with respect to year of sale, and such distributions will be taxable to
shareholders.

Prior to the closing of each Reorganization, the Selling Fund will, and the
Buying Fund may, declare a distribution to shareholders, which together with all
previous distributions, will have the effect of distributing to shareholders all
of its investment company taxable income (computed without regard to the
deduction for dividends paid) and net realized capital gains (after reduction by
any available capital loss carryforwards), if any, through the closing of the
Reorganization. These distributions will be taxable to shareholders.

A Fund's ability to carry forward capital losses and use them to offset future
gains may be limited. First, one Fund's "pre-acquisition losses" (including
capital loss carryforwards, net current-year capital losses, and unrealized
losses that exceed certain thresholds) cannot be used to offset unrealized gains
in another Fund that are "built in" at the time of the Reorganization and that
exceed certain thresholds ("non-de minimis built-in gains") for five calendar
years. Second, a portion of a Fund's pre-acquisition losses may become
unavailable to offset any gains at all. Third, any remaining pre-acquisition
losses will offset capital gains realized after the Reorganization and thus will
reduce subsequent capital gain distributions to a broader group of shareholders
than would have been the case absent such Reorganization. Therefore, in certain
circumstances, former shareholders of a Fund may pay taxes sooner, or pay more
taxes, than they would have had a Reorganization not occurred.

In addition, in each case the combined Fund resulting from each Reorganization
will have tax attributes that reflect a blending of the tax attributes of the
two Funds at the time of the Reorganization (including as affected by the rules
set forth above). Therefore, the shareholders of the Selling Fund will in each
case receive a proportionate share of any "built-in" (unrealized) gains in the
Buying Fund's assets, as well as any taxable gains realized by the Buying Fund
but not distributed to its shareholders prior to the Reorganization, when such
gains are eventually distributed by the Buying Fund.

The impact of the rules described above will depend on the relative sizes of,
and the losses and gains (both realized and unrealized) in, each Fund at the
time of the Reorganization and thus cannot be calculated precisely at this time.
As stated above, for five years beginning after the closing date, the combined
Fund will not be allowed to offset gains "built in" to either Fund at the time
of the Reorganization against capital losses (including capital loss
carryforwards) built in to the other Fund.

The realized and unrealized gains and losses of each Fund at the time of each
Reorganization will determine the extent to which the combining Funds'
respective losses, both realized and unrealized, will be available to reduce
gains realized by the combined Fund following the Reorganization, and
consequently the extent to which the combined Fund may be required to distribute
gains to its shareholders earlier than would have been the case absent the
Reorganization. The following paragraphs provide a brief

 64 RIVERSOURCE FUNDS -- PROXY STATEMENT


summary of the tax impact of each Reorganization had it occurred on June 30,
2007. As noted above, the tax impact of the Reorganization depends on each
Fund's relative tax situations at the time of the Reorganization and cannot be
calculated precisely at this time.

Proposal 1; Reorganization of Core Bond Fund into Diversified Bond Fund. As of
June 30, 2007, Core Bond Fund and Diversified Bond Fund had net realized capital
losses (including capital loss carryforwards) of approximately $2.51 million
(1.03% of the Fund's net assets) and $143.18 million (4.68% of the Fund's net
assets), respectively. If the Reorganization had occurred on June 30, 2007, the
combined fund would have had gross losses equal to approximately 4.76% of its
net assets, and the loss-limitation rules would not have affected the funds'
ability to use their losses, and the losses of Diversified Bond Fund would
potentially have protected gains recognized by the combined fund.

Proposal 2; Reorganization of Fundamental Growth Fund into Growth Fund. As of
June 30, 2007, Fundamental Growth Fund and Growth Fund had net unrealized
built-in gains equal to 10.5% and 9.1% of net assets, respectively, and Growth
Fund had losses (including capital loss carryforwards) of approximately $344.8
million (10% of the Fund's net assets). If the Reorganization had occurred on
that date, it is possible that it would have permitted the shareholders of
Fundamental Growth Fund to spread some of the tax cost associated with those
unrealized gains to the other shareholders of the combined fund, and
shareholders of Fundamental Growth Fund might also have benefited from the use
of Growth Fund's losses to reduce or eliminate the tax cost associated with
Growth Fund's unrealized gains.

Proposal 3; Reorganization of International Equity Fund into Disciplined
International Equity Fund. As of June 30, 2007, International Equity Fund and
Disciplined International Equity Fund had net unrealized built-in gains of 13.6%
and 7.4% of net assets, respectively. Neither Fund had any capital loss
carryforwards to help offset its gains. If the Reorganization had occurred on
June 30, 2007, it is possible that it would have permitted the shareholders of
International Equity Fund to spread some of the tax cost of their Fund's
unrealized gains to the other shareholders of the combined Fund.

Proposals 4, 5 and 6; Reorganizations of each of Massachusetts Tax-Exempt Fund,
Michigan Tax-Exempt Fund and Ohio Tax-Exempt Fund into Tax-Exempt High Income
Fund. As of June 30, 2007 of the Selling Funds and Tax-Exempt High Income Fund,
only Massachusetts Tax-Exempt Fund had net realized capital losses (that is,
capital loss carryforwards, net of gains recognized year to date), and those
were extremely modest. Its losses (including capital loss carryforwards) were
$0.13 million (0.26% of the Fund's net assets). At that time, the Buying Fund,
which is considerably larger than any of the Selling Funds, had modest
unrealized ("built-in") capital gains. If any or all the Reorganizations of
these Funds into Tax-Exempt High Income Fund had occurred on June 30, 2007, the
combined fund would have been technically subject to the loss-limitation rules
described above, but those rules would not likely have prevented the use of such
losses; Tax-Exempt High Income Fund's built-in gains would potentially have
caused the shareholders of the Selling Fund in each case to receive
distributions somewhat earlier, and in higher amounts than they would have
absent the Reorganization.

Proposal 7; Reorganization of Value Fund into Diversified Equity Income Fund. As
of June 30, 2007, Value Fund and Diversified Equity Income Fund had net
unrealized built-in gains equal to 12.9% and 24.8% of net assets, respectively.
Neither Fund had any capital loss carryforwards to help offset its gains. If the
Reorganization had occurred on June 30, 2007, the combined fund's built-in gains
would have been substantially larger, both in absolute terms and as a percentage
of net assets, than those of Value Fund, and so it is possible that the
Reorganization would potentially have caused Value Fund shareholders to receive
distributions somewhat earlier, and in higher amounts, than they would have
absent the Reorganization.

The tax principles described above will remain true; their application and, at a
minimum, the specific percentages noted above will change prior to each
Reorganization, because of market developments, any pre-Reorganization
realignments (including, in the case of Fundamental Growth Fund, International
Equity Fund and Value Fund, realignments anticipated in connection with the
termination of the funds' subadvisers on or about Nov. 16, 2007) or other sales
of portfolio securities and shareholder activity in the Funds, among other
changes.

This description of the federal income tax consequences of the Reorganizations
does not take into account your particular facts and circumstances. Consult your
own tax adviser about the effect of state, local, foreign, and other tax laws.

REASONS FOR THE PROPOSED REORGANIZATIONS AND BOARD DELIBERATIONS

The Board believes that each proposed Reorganization will be advantageous to
Selling Fund shareholders based on its consideration of the following matters:

- - TERMS AND CONDITIONS OF THE REORGANIZATION. The Board considered the terms and
  conditions of each Reorganization as described in the previous paragraphs.

- - TAX CONSEQUENCES. The Board considered the tax-free nature of each
  Reorganization. The Board also considered the relative tax situations of each
  Fund and the resulting tax impact of the Reorganization to Selling Fund
  shareholders, and noted that the benefits of each Reorganization will outweigh
  any resulting tax cost to shareholders. With respect to the proposed
  Reorganizations of Massachusetts Tax-Exempt Fund, Michigan Tax-Exempt Fund and
  Ohio Tax-Exempt Fund ("Single State

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 65


  Funds") into Tax-Exempt High Income Fund, the Board considered the impact on
  shareholders of the Single State Funds of the expected taxability of
  distributions from the Buying Fund for state and local tax purposes. In this
  regard, the Board also considered the historic performance of the Funds and
  noted that, even when taking into account the state and local taxes to which
  shareholders of Tax-Exempt High Income Fund would be subject on distributions
  from the Fund, the after-tax performance of Tax-Exempt High Income Fund was
  higher than that of the Single State Funds (see "Performance and Other
  Factors" below).

- - CONTINUITY OF INVESTMENT. The Board took into account the fact that,
  currently, each Selling Fund and the corresponding Buying Fund have similar or
  identical investment objectives and, except as noted below and as discussed in
  more detail under each proposal, similar investment strategies. In particular,
  for each Reorganization:

  Core Bond Fund into Diversified Bond Fund: The Board noted that Diversified
  Bond Fund's primary objective of providing shareholders with a high level of
  current income, while conserving the value of the investment for the longest
  period of time, is similar to that of Core Bond Fund, which is to provide
  shareholders with a high total return through current income and capital
  appreciation. The Board also noted that the Funds shared a common benchmark,
  the Lehman Brothers Aggregate Bond Index.

  Fundamental Growth Fund into Growth Fund: The Board considered that the Funds
  shared a common investment objective of providing shareholders with long-term
  capital growth. The Board also noted the similarity in investment strategies
  (considering that, although both Funds had RiverSource Investments as an
  investment adviser, Fundamental Growth Fund had been subadvised by GSAM and
  Wellington Management). In this regard, the Board noted that both Funds shared
  a common benchmark, the Russell 1000 Growth Index.

  International Equity Fund into Disciplined International Equity Fund: The
  Board considered that the Funds shared a common investment objective of
  providing shareholders with long-term capital growth. The Board also noted the
  similarity in investment strategies (considering that, although both Funds had
  RiverSource Investments as an investment adviser, International Equity Fund
  had been subadvised by The Boston Company and Marsico). In this regard, the
  Board noted that both Funds shared a common benchmark, the MSCI EAFE Index.

  Single State Funds into Tax-Exempt High Income Fund: The Board considered the
  principal difference between the Funds, that unlike Tax-Exempt High Income
  Fund, each Single State Fund, as its investment objective, seeks to generate
  income that is exempt not only from federal income taxes but also state and
  local taxes. The Board further considered that, whereas each of the Single
  State Funds invest in securities exempt from a particular state or local tax,
  the combined portfolio would continue to consist of municipal securities which
  are generally exempt from federal tax, and that the holdings of each of the
  Single State Funds are eligible holdings of Tax-Exempt High Income Fund. In
  this regard, however, the Board noted that the Single State Funds continue to
  be faced with a limited supply of investment opportunities in these states,
  whereas, Tax-Exempt High Income Fund, as a national tax-exempt fund, has a
  much broader investment universe from which to seek to generate high current
  income.

  Value Fund into Diversified Equity Income Fund: The Board considered that
  Diversified Equity Income Fund had a primary objective of seeking a high level
  of current income, whereas this was a secondary objective for Value Fund. In
  this regard, the Board considered that, although both Funds had RiverSource
  Investments as an investment adviser, Value Fund had been subadvised by Lord
  Abbett, but observed that both Funds were managed against the same benchmark,
  the Russell 1000(R) Value Index, and that a substantial portion of Value
  Fund's holdings pay a dividend and thus are eligible holdings for Diversified
  Equity Income Fund.

- - EXPENSE RATIOS. The Board considered the relative expenses of the Funds.
  Specifically, the Board considered that, as of the end of each Fund's most
  recent fiscal year, the net expense ratios for each Selling Fund's Class A
  shares (before giving effect to any applicable performance incentive
  adjustment and excluding interest and fee expenses related to participation in
  certain inverse floater programs) were higher than or equal to the pro forma
  expense ratios for the corresponding Buying Fund's Class A shares (adjusted to
  reflect current fees, before giving effect to any applicable performance
  incentive adjustment and excluding interest and fee expenses related to
  participation in certain inverse floater programs). The Board also evaluated
  the anticipated expense ratio impacts to each Funds' other share classes. In
  particular, for each Reorganization (unless otherwise specified, discussion of
  expense ratio impacts are with respect to a Fund's Class A shares):

  Core Bond Fund into Diversified Bond Fund: The Board considered that, based on
  current commitments of the investment manager and its affiliates to waive fees
  and cap expenses, net expense ratios for Class A shares, Class B shares, Class
  C shares, Class R4 and Class W shares of Core Bond Fund would remain the same
  or fall slightly after the Reorganization. Although modest increases in
  expense ratios for Class R2 shares, Class R3 shares and Class R5 shares of
  Core Bond Fund are expected as a result of the Reorganization, the Board
  observed that there are no current public shareholders that own such share
  classes. With respect to Class I shares, the Board considered that the only
  shareholders are affiliated funds-of-funds, and although the expense ratio of
  Class I shares is expected to increase modestly as a result of the
  Reorganization, and such

 66 RIVERSOURCE FUNDS -- PROXY STATEMENT


  increase will contribute to a modest increase in the overall underlying
  expenses realized by the funds-of-funds investing in the Fund, such increases
  would not be material to the overall expense ratios for the funds-of-funds.
  The Board also considered that, based on current commitments of the investment
  manager and its affiliates to waive fees and cap expenses, similar impacts are
  expected for Diversified Bond Fund, specifically, that in share classes where
  there are public shareholders, expense ratios would remain the same or fall
  slightly, in share classes where there are no public shareholders, expense
  ratios may increase modestly, but that in Class I shares, expense ratios are
  expected to remain the same (approximately 0.53%).

  Fundamental Growth Fund into Growth Fund: The Board considered that Growth
  Fund is not currently subject to any commitment by the investment manager and
  its affiliates to waive fees or cap expenses, and although the investment
  manager and its affiliates have agreed to waive fees and cap expenses on
  Fundamental Growth Fund to 1.42%, Fundamental Growth Fund's total expense
  ratio (before giving effect to any performance incentive adjustment) was
  1.41%. The Board observed that total expenses (before giving effect to any
  applicable performance incentive adjustment) of Fundamental Growth Fund would
  decline significantly (approximately 0.31%) as a result of the Reorganization,
  while total expenses of Growth Fund would remain the same or fall slightly.

  International Equity Fund into Disciplined International Equity Fund: The
  Board considered that the expenses of International Equity Fund (before giving
  effect to any applicable performance incentive adjustment) would decline
  significantly (approximately 0.13%) on a gross or total expense basis and
  (approximately 0.10%) on a net basis (based on current commitments of the
  investment manager and its affiliates to waive fees and cap expenses, and on
  new commitments scheduled to go effective on Nov. 1, 2007), as a result of the
  Reorganization. The Board also considered that, based on current commitments
  of the investment manager and its affiliates, the expenses of Disciplined
  International Equity Fund would remain the same or fall slightly as a result
  of the Reorganization, but noted that, under new commitments scheduled to go
  effective on Nov. 1, 2007 (unrelated to and irrespective of the
  Reorganization), Class R4 shares would experience a modest increase in
  expenses.

  Single State Funds into Tax-Exempt High Income Fund: The Board considered
  that, based both on current commitments of the investment manager and its
  affiliates to waive fees and cap expenses, and on new commitments to waive
  fees and cap expenses scheduled to go effective on Dec. 1, 2007 (excluding
  interest and fee expenses associated with the Funds' participation in inverse
  floater programs), total expenses on a net basis would be the same for each
  Single State Fund (equal to 0.79%) both prior to and following these
  Reorganizations. The Board also considered that investment in inverse floater
  programs by each Fund will vary, and that, for the most recent fiscal year,
  each of the Single State Funds include in its expense ratio between 0.02% and
  0.04% of expenses related to participation in inverse floater programs,
  whereas Tax-Exempt High Income Fund included 0.26% of such expenses. The Board
  recognized that, when a fund participates in an inverse floater program, the
  fee and interest expenses associated with participation in inverse floater
  programs are typically offset by incremental interest income earned through
  such programs. In this regard, the Board considered that, excluding these
  inverse floater program expenses, total expenses of the Single State Funds,
  which range from 1.02% to 1.06%, would decline significantly to approximately
  0.83%.

  Value Fund into Diversified Equity Income Fund: The Board considered that
  total expenses (before giving effect to any applicable performance incentive
  adjustment) of Value Fund would decline significantly (approximately 0.37% on
  a gross or total expense basis and approximately 0.20% on a net basis (based
  on current commitments of the investment manager and its affiliates to waive
  fees and cap expenses)) as a result of the Reorganization, while total
  expenses of Diversified Equity Income Fund would remain the same or fall
  slightly.

- - ECONOMIES OF SCALE. The Board observed that by combining the Funds, in
  addition to potential immediate economies of scale of a larger fund, the
  combined Fund would be able take advantage of other economies of scale
  associated with a larger fund. For example, a larger fund may realize
  breakpoints more quickly and it should have an enhanced ability to effect
  portfolio transactions on more favorable terms and should have greater
  investment flexibility. Furthermore, the Board also considered that higher
  aggregate net assets resulting from each Reorganization and the opportunity
  for net cash inflows (or reduced outflows) may reduce the risk that, if net
  assets of the Selling Fund fail to grow, or diminish, its total expense ratio
  could rise from current levels as fixed expenses, such as audit expenses and
  accounting expenses that are charged on a per Fund basis, become a larger
  percentage of net assets.

- - COSTS. The Board considered the fact that the investment manager and its
  affiliates have agreed to bear all solicitation expenses in order to achieve
  shareholder approval of the Reorganization and to bear any other costs of
  effecting each Reorganization (other than any brokerage or other transaction
  costs associated with the sale or purchase of portfolio securities in
  connection with the Reorganization).


- - DILUTION. The Board considered the fact that the Reorganization will not
  dilute the interests of the current shareholders because it would be effected
  on the basis of the relative net asset value per share of the Selling Fund and
  Buying Fund, respectively. Thus, for example, a Class A shareholder of a
  Selling Fund will receive Class A shares of the corresponding Buying Fund
  equal in value to his or her Class A shares in the Selling Fund at the time of
  the Reorganization.

                                         RIVERSOURCE FUNDS -- PROXY STATEMENT 67


- - PERFORMANCE AND OTHER FACTORS. The Board considered the relative performance
  records of each of the Funds, noting, however, that past performance is no
  guarantee of future results. The Board also considered the fact that the
  Reorganizations should allow for a more concentrated selling effort by the
  Funds' underwriter, thereby potentially benefiting each of the Funds, and that
  reduced outflows or increased inflows could help the Selling Fund shareholders
  achieve further economies of scale (see "Economies of Scale" above). The Board
  further took into account the investment manager's belief that each Selling
  Fund, as a stand-alone fund, was unlikely to experience any growth in assets
  from investor inflows in the near term. In particular, for each
  Reorganization, the Board observed:

  Core Bond Fund into Diversified Bond Fund: The Board noted that, on an
  absolute basis, the performance of Diversified Bond Fund was substantially
  stronger than the performance of Core Bond Fund. The Board noted the weak
  asset level of Core Bond Fund and its relatively weak prospects for asset
  growth, particularly compared to Diversified Bond Fund. The Board accorded
  particular weight to the fact that Diversified Bond Fund had substantially
  greater assets than Core Bond Fund, noting that Diversified Bond Fund was more
  than 10 times the size of Core Bond Fund.

  Fundamental Growth Fund into Growth Fund: The Board noted that Growth Fund's
  performance was substantially stronger than that of Fundamental Growth Fund
  for both the one and three year periods (both on an absolute basis and when
  compared to their respective peer groups). The Board also noted Fundamental
  Growth Fund's small asset size and its relatively weak prospects for asset
  growth, particularly compared to Growth Fund. The Board accorded particular
  weight to the fact that Growth Fund was more than 10 times the size of
  Fundamental Growth Fund.

  International Equity Fund into Disciplined International Equity Fund: The
  Board noted that although Disciplined International Equity Fund has a shorter
  period of operations than International Equity Fund, its performance during
  this brief period has been strong and significantly better than that of
  International Equity Fund for the same period. The Board also noted that,
  notwithstanding its short period of operations, Disciplined International
  Equity Fund has garnered more assets relative to International Equity Fund.

  Single State Funds into Tax-Exempt High Income Fund: The Board noted that
  Tax-Exempt High Income Fund's performance was stronger than the performance
  for each of the Single State Funds for both the one and three year periods
  (both on an absolute basis and when compared to their respective peer groups).
  The Board also observed that Tax-Exempt High Income Fund's performance was
  stronger than that of the Single State Funds even when taking into account
  state and local taxes (i.e., of each relevant state covered by the Single
  State Funds) to which shareholders of Tax-Exempt High Income Fund would be
  subject. In this regard, it was noted that Tax-Exempt High Income Fund's
  relatively strong performance, when compared to the performance of the Single
  State Funds, may reflect the benefits of having access to a broader investment
  universe. The Board further observed that due to the relatively small asset
  size of each Single State Fund (each has less than $60 million of assets), the
  continued strength and viability of the single-state products were
  questionable and that, in this regard, Tax-Exempt High Income Fund had grown
  to more than 15 times the size of the largest of the Single State Funds.

  Value Fund into Diversified Equity Income Fund: The Board noted that
  Diversified Equity Income Fund's performance was substantially stronger than
  that of Value Fund (both on an absolute basis and compared to their respective
  peer groups). The Board also discussed Value Fund's small asset level and its
  relatively weak prospects for asset growth, particularly compared to
  Diversified Equity Income Fund. The Board accorded particular weight to the
  fact that Diversified Equity Income Fund was almost 20 times the size of Value
  Fund.

- - POTENTIAL BENEFITS TO THE INVESTMENT MANAGER AND ITS AFFILIATES. The Board
  considered the potential benefits from the Reorganization that could be
  realized by the investment manager and its affiliates. For Funds that are
  currently sub-advised, the Board recognized that potential benefits to the
  investment manager consist principally of the savings associated with the
  elimination of the expense of paying the subadviser(s) and, for all Funds, the
  elimination of expenses incurred in duplicative efforts to administer separate
  Funds. The Board also noted, however, that shareholders of the Selling Fund
  are expected to benefit over time from any decrease in overall operating
  expense ratios resulting from the proposed Reorganization.

BOARDS' DETERMINATIONS

After considering the factors described above and other relevant information, at
meetings held on July 10-12, 2007, Sept. 10-11, 2007, [and Nov. 7-8, 2007] each
Selling Fund Board, including a majority of the independent Board members, found
that participation in the Reorganization is in the best interests of the Selling
Fund and that the interests of existing shareholders of the Fund will not be
diluted as a result of the Reorganization.

The Board of Directors of each Buying Fund approved the Agreement at a meeting
held on Sept. 10-11, 2007. Among other factors, the Board members considered the
terms of the Agreement, the provisions intended to avoid the dilution of
shareholder interests and the anticipated tax consequences of the
Reorganization. The Board found that participation in each Reorganization is in
the best interests of the Buying Fund and that the interests of existing
shareholders of the Buying Fund will not be diluted as a result of the
Reorganization.

SECTION B -- PROPOSAL FOR MINNESOTA TAX-EXEMPT FUND

PROPOSAL 8. APPROVE OR REJECT CHANGE OF INVESTMENT COMPANY CLASSIFICATION TO
"NON-DIVERSIFIED" FOR MINNESOTA TAX-EXEMPT FUND

Reference to the "Fund" in this proposal is a reference to Minnesota Tax-Exempt
Fund.

The Board has approved, and recommends that shareholders approve, a proposal to
change the classification of the Fund from a "diversified" fund to a
"non-diversified" fund, as such terms are defined under the Investment Company
Act of 1940, as amended.

FUND CLASSIFICATION. The Fund is currently classified as a diversified fund
under the 1940 Act. This means that the Fund may not, with respect to 75% of its
total assets, invest more than 5% of its total assets in any one issuer or
purchase more than 10% of the outstanding voting securities of any one issuer.
With respect to the remaining 25% of the Fund's total assets, there is no
limitation on the amount of assets the Fund may invest in any one issuer.
Section 13(a)(1) of the 1940 Act and Rule 13a-1 thereunder generally provide
that if a non-diversified fund actually operates as if it were a diversified
fund for a period of three years, its classification under the 1940 Act will
convert automatically from non-diversified to diversified. The Fund's current
classification as a diversified fund resulted from its operating as a
diversified fund for more than three years. The Fund is seeking shareholder
approval to restore its non-diversified classification because its investment
manager believes that the Fund will benefit from the additional investment
flexibility of investing in a smaller number of issuers, and because a
diversified fund may convert to non-diversified status only with shareholder
approval.

The Fund is also subject to certain additional diversification requirements
under the Internal Revenue Code of 1986, as amended (the "Code"). With respect
to 50% of the Fund's total assets, the Fund may not invest more than 5% of its
total assets in any one issuer and may not purchase more than 10% of the
outstanding voting securities of any one issuer. With respect to the remaining
50% of the Fund's total assets, the Fund may not invest more than 25% of its
assets in any one issuer. If this proposal is approved, the Fund will continue
to be subject to the Code's diversification requirements with respect to
regulated investment companies.

REASONING AND POTENTIAL RISK. The Fund's investment manager is seeking to regain
the flexibility to invest more of the Fund's assets in a small number of
issuers. The Fund's investment manager believes this flexibility will allow the
Fund to better pursue its investment objective of providing shareholders with a
high level of income generally exempt from federal income tax, as well as from
Minnesota state and local tax. Even if this proposal is approved, the Fund's
investment manager may or may not operate the Fund as non-diversified, depending
on its assessment of the investment opportunities available to the Fund from
time to time. (Of course, pursuant to Rule 13a-1, should the Fund operate as a
"diversified" fund for a period of three years, it would revert to its
diversified status).

A non-diversified Fund is subject to greater risk. The Fund may invest more of
its assets in fewer issuers than if it were a diversified fund. Because each
investment may have a greater effect on the Fund's performance, the Fund may be
more exposed to the risks of loss and volatility than a fund that invests more
broadly.

BOARD RECOMMENDATION AND VOTE REQUIRED. The Board recommends that you vote to
approve to change the classification of the Fund to non-diversified. Approval of
the proposed change requires the favorable vote of the lesser of (a) a majority
of the Fund's outstanding voting securities or (b) 67% or more of the voting
securities present at the meeting, so long as more than 50% of the outstanding
voting securities are present. If shareholders approve the proposed change, it
will take effect shortly after the shareholder meeting. If the proposed change
is not approved, the Fund will continue to operate as a diversified fund.

returned without instructions will be voted in favor of all proposals of Fund(s)
for which you own shares.

All votes count toward a quorum, regardless of how they are voted (For, Against
or Abstain). Broker non-votes will be counted toward a quorum but not toward the
approval of any proposals. (Broker non-votes are shares for which the underlying
owner has not voted and the broker holding the shares does not have authority to
vote.)

If your shares are held in an IRA account with Ameriprise Trust Company as
custodian, you have the right to instruct the IRA Custodian how to vote those
shares. The IRA Custodian will vote any shares for which it has not received
voting instructions in proportionately the same manner -- either For, Against,
or Abstain -- as other Fund shareholders have voted.

REVOKING YOUR PROXY. If you change your mind after you vote and you can attend
the meeting, simply inform the Secretary at the meeting that you will be voting
your shares in person. Also, if you change your mind after you vote, but cannot
attend the meeting, you may change your vote or revoke it by mail, telephone or
internet.

SIMULTANEOUS MEETINGS. The meeting will be held simultaneously with meetings of
other RiverSource mutual funds. Each proposal will be voted on separately by
shareholders of a Fund. If any shareholder objects to the holding of
simultaneous meetings, the shareholder may move for an adjournment of his or her
Fund's meeting to a time immediately after the simultaneous meetings so that a
meeting of that Fund may be held separately. If a shareholder makes this motion,
the persons named as proxies will take into consideration the reasons for the
objection in deciding whether to vote in favor of the adjournment.

SOLICITATION OF PROXIES. The Board is asking for your vote and for you to vote
as promptly as possible. The investment manager will pay the expenses of the
solicitation. Supplementary solicitations may be made by mail, telephone,
electronic means or personal contact.

SHAREHOLDER PROPOSALS. No proposals were received from shareholders. RiverSource
Funds are not required to hold regular meetings of shareholders each year.
However, meetings of shareholders are held from time to time and proposals of
shareholders that are intended to be presented at future shareholder meetings
must be submitted in writing to RiverSource Funds in reasonable time prior to
the solicitation of proxies for the meeting.

DISSENTERS' RIGHT OF APPRAISAL. Under Sections 302A.471 and 302A.473 of the
Minnesota Business Corporation Act, Selling Fund shareholders (except Michigan
Tax-Exempt Fund, Ohio Tax-Exempt Fund and Michigan Tax-Exempt Fund, which are
organized as Massachusetts business trusts) are entitled to assert dissenters'
rights in connection with the Reorganization and obtain payment of the "fair
value" of their shares, provided that they comply with the requirements of
Minnesota law. A copy of the relevant provisions is attached as Exhibit B.

Notwithstanding the provisions of Minnesota law, the SEC has taken the position
that use of state appraisal procedures by a mutual fund would be a violation of
Rule 22c-1, the forward pricing rule, under the 1940 Act. This rule states that
no mutual fund may redeem its shares other than at net asset value next computed
after receipt of a request for redemption. It is the SEC's position that Rule
22c-1 supersedes appraisal provisions in state statutes.

In the interest of ensuring equal valuation for all shareholders, dissenters'
rights will be determined in accordance with the SEC's interpretation. As a
result, if any shareholder elects to exercise dissenters' rights under Minnesota
law, the Selling Fund intends to submit this question to a court of competent
jurisdiction. In that event, a dissenting shareholder would not receive any
payment until the end of the court proceeding.

OTHER BUSINESS. The Board does not know at this time of any other business to
come before the meetings. If something does come up, the proxies will use their
best judgment to vote for you on the matter.

ADJOURNMENT. In the event that not enough votes are received by the time
scheduled for the meeting, the persons named as proxies may move for one or more
adjournments of the meeting for a period of not more than 120 days in the
aggregate to allow further solicitation of shareholders on the proposals. Any
adjournment requires the affirmative vote of a majority of the voting power of
the shares present at the meeting. The persons named as proxies will vote in
favor of adjournment those shares they are entitled to vote that have voted in
favor of the proposal. They will vote against any adjournment those shares that
have voted against the proposal. The investment manager will pay the costs of
any additional solicitation and of any adjourned meeting. A shareholder vote may
be taken on one or more of the items in this proxy statement prior to
adjournment if sufficient votes have been received.

     interests may be significant, in excess of 25% of the Fund, such that these

(b)  Expense ratio is based on total expenses of the Fund before reduction of
     earnings and bank fee credits on cash balances.
(c)  The Investment Manager and its affiliates waived/reimbursed the Fund for
     certain expenses. Had they not done so, the annual ratios of expenses for
     Class C would have been 1.58% excluding interest and fee expense and 1.85%
     including interest and fee expense for the six months ended May 31, 2007
     and 1.59% and 1.57% excluding interest and fee expense and 1.85% and 1.74%
     including interest and fee expense for the years ended Nov. 30, 2006 and
     2005, respectively.
(d)  Adjusted to an annual basis.
(e)  Ratios include interest and fee expense related to the Fund's participation
     in certain inverse floater programs. Due to an equal increase in interest
     income from fixed rate municipal bonds held in trust, there is no impact on
     the Fund's net assets, net asset value per share, total return or net
     investment income.
(f)  Total return does not reflect payment of a sales charge.

 100 RIVERSOURCE FUNDS -- PROXY STATEMENT


EXHIBIT A

FORM OF AGREEMENT AND PLAN OF REORGANIZATION

This Agreement and Plan of Reorganization dated as of           (the
"Agreement") is between each selling entity identified in Schedule A hereto
(each a "Selling Corporation")(1), on behalf of each series thereof identified
in Schedule A hereto as a Selling Fund (each a "Selling Fund"), each
corresponding buying entity identified in Schedule A hereto (each a "Buying
Corporation"), on behalf of each series thereof identified in Schedule A hereto
as the corresponding Buying Fund (each a "Buying Fund"), and RiverSource
Investments, LLC (solely for the purposes of Sections 3c and 11 of the
Agreement).

This Agreement shall be treated as if each reorganization between a Selling Fund
and its corresponding Buying Fund contemplated hereby had been the subject of a
separate agreement.

In consideration of their mutual promises, the parties agree as follows:

1.  SHAREHOLDER APPROVAL. Each Selling Fund will call a meeting of its
    shareholders for the purpose of approving the Agreement and the transactions
    it contemplates (each a "Reorganization"). Each Buying Fund agrees to
    furnish data and information, as reasonably requested, for the proxy
    statement to be furnished to shareholders of the corresponding Selling Fund.

2.  REORGANIZATION.

    a.  Plan of Reorganization. The Reorganization will be a reorganization
        within the meaning of Section 368 of the Internal Revenue Code of 1986,
        as amended (the "Code"). At the Closing, each Selling Corporation will
        convey all of the assets of each Selling Fund to the corresponding
        Buying Fund. Each Buying Fund will assume all liabilities of the
        corresponding Selling Fund. At the Closing, each Buying Corporation will
        deliver shares of each Buying Fund, including fractional shares, to the
        corresponding Selling Corporation. The number of shares will be
        determined by dividing the value of the net assets of shares of each
        Selling Fund, computed as described in paragraph 3(a), by the net asset
        value of one share of the corresponding Buying Fund, computed as
        described in paragraph 3(b). Each Selling Fund will not pay a sales
        charge on the receipt of the corresponding Buying Fund's shares in
        exchange for the assets of such Selling Fund. In addition, the
        shareholders of each Selling Fund will not pay a sales charge on
        distribution to them of shares of the corresponding Buying Fund.

    b.  Closing and Effective Time of the Reorganization. The Reorganization and
        all related acts necessary to complete the Reorganization (the
        "Closing") will occur on the first day on which the New York Stock
        Exchange (the "NYSE") is open for business following approval of
        shareholders of each Selling Fund and receipt of all necessary
        regulatory approvals, or such later date as the parties may agree.

3.  VALUATION OF NET ASSETS.

    a.  The net asset value of shares of each Selling Fund will be computed as
        of the close of regular trading on the NYSE on the business day
        immediately preceding the day of Closing (the "Valuation Date") using
        the valuation procedures in the corresponding Buying Fund's prospectus.

    b.  The net asset value per share of shares of each Buying Fund will be
        determined as of the close of regular trading on the NYSE on the
        Valuation Date, using the valuation procedures in each Buying Fund's
        prospectus.

    c.  At the Closing, each Selling Fund will provide the corresponding Buying
        Fund with a copy of the computation showing the valuation of the net
        asset value per share of shares of such Selling Fund on the Valuation
        Date. Each Buying Fund will provide the corresponding Selling Fund with
        a copy of the computation showing the determination of the net asset
        value per share of shares of such Buying Fund on the Valuation Date.
        Both computations will be certified by an officer of RiverSource
        Investments, LLC, the investment manager.

4.  LIQUIDATION AND DISSOLUTION OF THE SELLING FUND.

    a.  As soon as practicable after the Valuation Date, each Selling
        Corporation will liquidate each Selling Fund and distribute shares of
        each class of the corresponding Buying Fund to such Selling Fund's
        shareholders of record of such class. Each Buying Fund will establish
        shareholder accounts in the names of each corresponding Selling Fund
        shareholder, representing the respective pro rata number of full and
        fractional shares of such class of the Buying Fund due to each
        shareholder. All issued and outstanding shares of each Selling Fund will
        simultaneously be cancelled on the books of each Selling Corporation.
        Each Buying Fund or its transfer agent will establish shareholder
        accounts in accordance with instructions from the corresponding Selling
        Corporation.

    RiverSource Massachusetts Tax-Exempt Fund, RiverSource Michigan Tax-Exempt

                                        RIVERSOURCE FUNDS -- PROXY STATEMENT A.1


    b.  Immediately after the Valuation Date, the share transfer books of each
        Selling Corporation relating to each Selling Fund will be closed and no
        further transfer of shares will be made.

    c.  Promptly after the distribution, each Buying Fund or its transfer agent
        will notify each shareholder of the corresponding Selling Fund of the
        number of shares distributed to the shareholder and confirm the
        registration in the shareholder's name.

    d.  As promptly as practicable after the liquidation of each Selling Fund,
        and in no event later than twelve months from the date of the Closing,
        each Selling Fund will be dissolved.

        decree or judgment.

    j.  Contracts. Except for contracts and agreements previously disclosed to

        transactions contemplated by it will not conflict with or constitute a
        breach of, any material contract to which the Selling Fund is subject.
        The transactions will not result in any violation of the provisions of

       this Agreement will be validly issued, fully paid and non-assessable

9.  CONDITIONS TO OBLIGATIONS OF THE SELLING CORPORATION AND THE BUYING
    CORPORATION. The obligations of each of the Selling Corporation and the
    Buying Corporation with respect to each Reorganization are subject to the
    satisfaction of the following conditions:

    Tax Opinion. With respect to each Reorganization, each Selling Fund shall
    have received a favorable opinion of Ropes & Gray LLP satisfactory to each
    Selling Fund, and each Buying Fund shall have received a favorable opinion
    of Ropes & Gray LLP satisfactory to each Buying Fund, each substantially to
    the effect that, on the basis of existing provisions of the Code, Treasury
    regulations promulgated thereunder, current administrative rules and court
    decisions, generally for federal income tax purposes:

    - The transactions contemplated by this Agreement will constitute a
      reorganization within the meaning of Section 368(a) of the Code, and each
      Selling Fund and the corresponding Buying Fund will each be "a party to a
      reorganization" within the meaning of Section 368(b) of the Code;

    - No gain or loss will be recognized by each Selling Fund upon the transfer
      of its assets to the corresponding Buying Fund in exchange for the
      acquisition shares or upon the distribution of the acquisition shares by
      such Selling Fund to its shareholders in liquidation, as contemplated in
      paragraph 1 hereof;

                                        RIVERSOURCE FUNDS -- PROXY STATEMENT A.5


    - No gain or loss will be recognized by each Buying Fund upon receipt of the
      assets of the corresponding Selling Fund in exchange for acquisition
      shares and the assumption by each Buying Fund of the liabilities of such
      Selling Fund as contemplated in paragraph 1 hereof;

    - The basis in the hands of each Buying Fund of the assets of each Selling
      Fund transferred to the Buying Fund in the Reorganization will be the same
      as the basis of such assets in the hands of such Selling Fund immediately
      prior to the transfer;

    - The holding periods of the assets of each Selling Fund in the hands of
      each Buying Fund will include the periods during which such assets were
      held by each Selling Fund;

    - No gain or loss will be recognized by each Selling Fund's shareholders
      upon the exchange of their shares of each Selling Fund for the acquisition
      shares;

    - The aggregate basis of the acquisition shares each Selling Fund
      shareholder receives in connection with the Reorganization will be the
      same as the aggregate basis of his or her Selling Fund's shares exchanged
      therefor;

    - Each Selling Fund shareholder's holding period for the acquisition shares
      will be determined by including the period for which he or she held the
      Selling Fund's shares exchanged therefor, provided that the shareholder
      held such Selling Fund's shares as capital assets; and

    - Each Buying Fund will succeed to and take into account the items of the
      Selling Fund described in Section 381(c) of the Code, subject to the
      conditions and limitations specified in Sections 381, 382, 383 and 384 of
      the Code and the regulations thereunder.

    The opinion will be based on certain factual certifications made by officers
    of the Selling Fund and the corresponding Buying Fund will also be based on
    customary assumptions. The opinion is not a guarantee that the tax
    consequences of the Reorganization will be as described above.

    Ropes & Gray LLP will express no view with respect to the effect of the
    Reorganization on any transferred asset as to which any unrealized gain or
    loss is required to be recognized at the end of a taxable year (or on the
    termination or transfer thereof) under federal income tax principles.

10. AMENDMENT; TERMINATION; NON-SURVIVAL OF COVENANTS, WARRANTIES AND
    REPRESENTATIONS.

    a.  This Agreement may be amended in writing if authorized by the respective
        Boards of Directors/Trustees. The Agreement may be amended at any time
        before or after approval by the shareholders of each Selling Fund.

    b. At any time prior to the Closing, any of the parties may waive in writing
       (i) any inaccuracies in the representations and warranties made to it and

       benefit.

    c.  Each party hereto may terminate this Agreement at any time prior to the
        Closing by notice to the other party if a material condition to its
        performance or a material covenant of the other party is not fulfilled
        on or before the date specified for its fulfillment or a material breach
        of this Agreement is made by the other party and is not cured.

    d. This Agreement may be terminated by any party at any time prior to the
       Closing, whether before or after approval by the shareholders of each
       Selling Fund, without any liability on the part of any party or its
       respective directors/trustees, officers, or shareholders, on written
       notice to the other party, and shall be terminated without liability as
       of the close of business on December 31, 2008, or a later date agreed
       upon by the parties, if the Closing is not on or prior to that date.

    e.  The representations, warranties and covenants contained in this
        Agreement, or in any document delivered in connection with this
        Agreement, will survive the Reorganization.

11. EXPENSES. RiverSource Investments, LLC and its affiliates will pay all
    solicitation expenses in order to achieve shareholder approval of each
    Reorganization whether or not the Reorganization is completed and will bear
    the other costs of effecting each Reorganization (other than any brokerage
    or other transaction costs associated with the sale or purchase of portfolio
    securities in connection with a Reorganization).

12. GENERAL.

    a.  Headings. The headings contained in this Agreement are for reference
        purposes only and will not affect the meaning or interpretation of this

       of Minnesota.

    Tax-Exempt Series Trust is on file with the Secretary of The Commonwealth of

                       THIS PAGE LEFT BLANK INTENTIONALLY


EXHIBIT B

MINNESOTA BUSINESS CORPORATION ACT SECTIONS 302A.471 AND 302A.473

Minnesota law requires that we provide you with a copy of the state law on
dissenters' rights. Notwithstanding the provisions of the law set out below, the
SEC has taken the position that use of state appraisal procedures by a
registered mutual fund such as the Fund would be a violation of Rule 22c-1, the
forward pricing rule, under the 1940 Act. As a result, if any shareholder elects
to exercise dissenters' rights under Minnesota law, the Fund intends to submit
this question to a court of competent jurisdiction. In that event, a dissenting
shareholder would not receive any payment until the end of the court proceeding.

302A.471. RIGHTS OF DISSENTING SHAREHOLDERS

SUBDIVISION 1. ACTIONS CREATING RIGHTS. A shareholder of a corporation may
dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:

(a) unless otherwise provided in the articles, an amendment of the articles that
    materially and adversely affects the rights or preferences of the shares of
    the dissenting shareholder in that it:

    (1) alters or abolishes a preferential right of the shares;

    (2) creates, alters, or abolishes a right in respect of the redemption of
        the shares, including a provision respecting a sinking fund for the
        redemption or repurchase of the shares;

    (3) alters or abolishes a preemptive right of the holder of the shares to
        acquire shares, securities other than shares, or rights to purchase
        shares or securities other than shares;

    (4) excludes or limits the right of a shareholder to vote on a matter, or to
        cumulate votes, except as the right may be excluded or limited through
        the authorization or issuance of securities of an existing or new class
        or series with similar or different voting rights; except that an
        amendment to the articles of an issuing public corporation that provides
        that section 302A.671 does not apply to a control share acquisition does
        not give rise to the right to obtain payment under this section;

    (5) eliminates the right to obtain payment under this subdivision;

(b) a sale, lease, transfer, or other disposition of property and assets of the
    corporation that requires shareholder approval under section 302A.661,
    subdivision 2, but not including a disposition in dissolution described in
    section 302A.725, subdivision 2, or a disposition pursuant to an order of a
    court, or a disposition for cash on terms requiring that all or
    substantially all of the net proceeds of disposition be distributed to the
    shareholders in accordance with their respective interests within one year
    after the date of disposition;

(c) a plan of merger, whether under this chapter or under chapter 322B, to which
    the corporation is a party, except as provided in subdivision 3, and except
    for a plan of merger adopted under section 302A.626;

(d) a plan of exchange, whether under this chapter or under chapter 322B, to
    which the corporation is a party as the corporation whose shares will be
    acquired by the acquiring corporation, except as provided in subdivision 3;

(e) a plan of conversion adopted by the corporation; or

(f) Any other corporate action taken pursuant to a shareholder vote with respect
    to which the articles, the bylaws, or a resolution approved by the board
    directs that dissenting shareholders may obtain payment for their shares.

SUBDIVISION 2. BENEFICIAL OWNERS.

(a) A shareholder shall not assert dissenters' rights as to less than all of the
    shares registered in the name of the shareholder, unless the shareholder
    dissents with respect to all the shares that are beneficially owned by
    another person but registered in the name of the shareholder and discloses
    the name and address of each beneficial owner on whose behalf the
    shareholder dissents. In that event, the rights of the dissenter shall be
    determined as if the shares as to which the shareholder has dissented and
    the other shares were registered in the names of different shareholders.

(b) A beneficial owner of shares who is not the shareholder may assert
    dissenters' rights with respect to shares held on behalf of the beneficial
    owner, and shall be treated as a dissenting shareholder under the terms of
    this section and section 302A.473, if the beneficial owner submits to the
    corporation at the time of or before the assertion of the rights a written
    consent of the shareholder.

SUBDIVISION 3. RIGHTS NOT TO APPLY.

(a) Unless the articles, the bylaws, or a resolution approved by the board
    otherwise provide, the right to obtain payment under this section does not
    apply to a shareholder of (1) the surviving corporation in a merger with
    respect to shares of the shareholder that are not entitled to be voted on
    the merger and are not canceled or exchanged in the merger or (2) the
    corporation whose shares will be acquired by the acquiring organization in a
    plan of exchange with respect to shares of the shareholder that are not
    entitled to be voted on the plan of exchange and are not exchanged in the
    plan of exchange.

                                        RIVERSOURCE FUNDS -- PROXY STATEMENT B.1


(b) If a date is fixed according to section 302A.445, subdivision 1, for the
    determination of shareholders entitled to receive notice of and to vote on
    an action described in subdivision 1, only shareholders as of the date
    fixed, and beneficial owners as of the date fixed who hold through
    shareholders, as provided in subdivision 2, may exercise dissenters' rights.

(c) Notwithstanding subdivision 1, the right to obtain payment under this
    section, other than in connection with a plan of merger adopted under
    section 302A.621, is limited in accordance with the following provisions:

    (1) The right to obtain payment under this section is not available for the
        holders of shares of any class or series of shares that is listed on the
        New York Stock Exchange or the American Stock Exchange or designated as
        a national market security on the Nasdaq Stock Market.

    (2) The applicability of clause (1) is determined as of:

SUBDIVISION 2. NOTICE OF ACTION. If a corporation calls a shareholder meeting at
which any action described in section 302A.471, subdivision 1 is to be voted
upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.

SUBDIVISION 3. NOTICE OF DISSENT. If the proposed action must be approved by the
shareholders and the corporation holds a shareholder meeting, a shareholder who
is entitled to dissent under section 302A.471 and who wishes to exercise
dissenters' rights must file with the corporation before the vote on the
proposed action a written notice of intent to demand the fair value of the
shares owned by the shareholder and must not vote the shares in favor of the
proposed action.

SUBDIVISION 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES.

(a) After the proposed action has been approved by the board and, if necessary,
    the shareholders, the corporation shall send to (i) all shareholders who
    have complied with subdivision 3, (ii) all shareholders who did not sign or
    consent to a written action that gave effect to the action creating the
    right to obtain payment under section 302A.471, and (iii) all shareholders
    entitled to dissent if no shareholder vote was required, a notice that

        certificated shares must be sent in order to obtain payment and the date
        by which they must be received;

        after the demand for payment is received;

 B.2 RIVERSOURCE FUNDS -- PROXY STATEMENT


    (4) A copy of section 302A.471 and this section and a brief description of
        the procedures to be followed under these sections.

(b) In order to receive the fair value of the shares, a dissenting shareholder
    must demand payment and deposit certificated shares or comply with any
    restrictions on transfer of uncertificated shares within 30 days after the
    notice required by paragraph (a) was given, but the dissenter retains all
    other rights of a shareholder until the proposed action takes effect.

SUBDIVISION 5. PAYMENT; RETURN OF SHARES.

(a) After the corporate action takes effect, or after the corporation receives a
    valid demand for payment, whichever is later, the corporation shall remit to
    each dissenting shareholder who has complied with subdivisions 3 and 4 the
    amount the corporation estimates to be the fair value of the shares, plus
    interest, accompanied by:

    (1) The corporation's closing balance sheet and statement of income for a
        fiscal year ending not more than 16 months before the effective date of
        the corporate action, together with the latest available interim
        financial statements;

    (2) An estimate by the corporation of the fair value of the shares and a
        brief description of the method used to reach the estimate; and

    (3) A copy of section 302A.471 and this section, and a brief description of
        the procedure to be followed in demanding supplemental payment.

(b) The corporation may withhold the remittance described in paragraph (a) from
    a person who was not a shareholder on the date the action dissented from was
    first announced to the public or who is dissenting on behalf of a person who
    was not a beneficial owner on that date. If the dissenter has complied with
    subdivisions 3 and 4, the corporation shall forward to the dissenter the
    materials described in paragraph (a), a statement of the reason for
    withholding the remittance, and an offer to pay to the dissenter the amount
    listed in the materials if the dissenter agrees to accept that amount in
    full satisfaction. The dissenter may decline the offer and demand payment
    under subdivision 6. Failure to do so entitles the dissenter only to the
    amount offered. If the dissenter makes demand, subdivision 7 and 8 apply.

(c) If the corporation fails to remit payment within 60 days of the deposit of
    certificates or the imposition of transfer restrictions on uncertificated
    shares, it shall return all deposited certificates and cancel all transfer
    restrictions. However, the corporation may again give notice under
    subdivision 4 and require deposit or restrict transfer at a later time.

SUBDIVISION 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.

SUBDIVISION 7. PETITION; DETERMINATION. If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in a court a petition requesting that
the court determine the fair value of the shares, plus interest. The petition
shall be filed in the county in which the registered office of the corporation
is located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation. The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of civil procedure. Nonresidents of this state may be served by registered
or certified mail or by publication as provided by law. Except as otherwise
provided, the rules of civil procedures apply to this proceeding. The
jurisdiction of the court is plenary and exclusive. The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares. The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter. The fair value of the shares as determined by the court is binding on
all shareholders, wherever located. A dissenter is entitled to judgment in cash
for the amount by which the fair value of the shares as determined by the court,
plus interest, exceeds the amount, if any, remitted under subdivision 5, but
shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.

SUBDIVISION 8. COSTS; FEES; EXPENSES.

(a) The court shall determine the costs and expenses of a proceeding under
    subdivision 7, including the reasonable expenses and compensation of any
    appraisers appointed by the court, and shall assess those costs and expenses
    against the corporation,

                                        RIVERSOURCE FUNDS -- PROXY STATEMENT B.3


    except that the court may assess part or all of those costs and expenses
    against a dissenter whose action in demanding payment under subdivision 6 is
    found to be arbitrary, vexatious, or not in good faith.

(b) If the court finds that the corporation has failed to comply substantially
    with this section, the court may assess all fees and expenses of any experts
    or attorneys as the court deems equitable. These fees and expenses may also
    be assessed against a person who has acted arbitrarily, vexatiously, or not
    in good faith in bringing the proceeding, and may be awarded to a party
    injured by those actions.

(c) The court may award, in its discretion, fees and expenses to an attorney for
    the dissenters out of the amount awarded to the dissenters, if any.

 Growth Fund                                                             0.66%

</Table>

For Growth Fund and Diversified Equity Income Fund, the fee includes an
adjustment under the terms of a performance incentive arrangement. For
Disciplined International Equity Fund, beginning Dec. 1, 2006, the fee may be
adjusted under the terms of a performance incentive arrangement. The adjustment
is computed by comparing the Fund's performance to the performance of an index
of comparable funds published by Lipper Inc. The index against which the Fund's
performance is currently measured for purposes of the performance incentive
adjustment is the Lipper Large-Cap Growth Funds Index for Growth Fund, the
Lipper International Large-Cap Core Funds Index for Disciplined International
Equity Fund and the Lipper Equity Income Funds Index for Diversified Equity
Income Fund. In certain circumstances, the Fund's Board may approve a change in
the index. The maximum adjustment (increase or decrease) is 0.12% of the Fund's
average net assets on an annual basis.

Under the Agreement, each Fund also pays taxes, brokerage commissions, and
nonadvisory expenses. A discussion regarding the basis for the Board approving
the Agreement is available in each Fund's most recent annual or semiannual
shareholder report.

</Table>

(a)  For Class A, Class B, Class C, Class R2, Class R3 and Class W shares, each
     fund has adopted a plan under Rule 12b-1 of the Investment Company Act of
     1940, as amended, that allows it to pay distribution and shareholder
     servicing-related expenses for the sale of shares. Because these fees are
     paid out of a fund's assets on an on-going basis, over time these fees will
     increase the cost of your investment and may cost you more than paying
     other types of distribution (sales) or servicing charges.
(b)  See "Buying and Selling Shares, Sales Charges, Class B and Class
     C -- contingent deferred sales charge alternative" for more information on
     the timing of conversion of Class B shares to Class A shares. Timing will
     vary depending on the date of your original purchase of the Class B shares.

DISTRIBUTION AND SERVICE FEES

The distribution and shareholder servicing fees for Class A, Class B, Class C,
Class R2, Class R3 and Class W are subject to the requirements of Rule 12b-1
under the Investment Company Act of 1940, as amended, and are used to reimburse
the distributor for certain expenses it incurs in connection with distributing a
fund's shares and providing services to fund shareholders. These expenses
include payment of distribution and shareholder servicing fees to financial
institutions that sell shares of the fund, up to 0.50% of the average daily net
assets of Class R2 shares sold and held through them and up to 0.25% of the
average daily net assets of Class A, Class B, Class C, Class R3 and Class W
shares sold and held through them. For Class A, Class B, Class R2, Class R3 and
Class W shares, the distributor begins to pay these fees immediately after
purchase. For Class C shares, the distributor begins to pay these fees one year
after purchase. Financial institutions also receive distribution fees up to
0.75% of the average daily net assets of Class C shares sold and held through
them, which the distributor begins to pay one year after purchase. For Class B
shares, and, for the first year after sale only, for Class C shares, the fund's
distributor retains the distribution fee of up to 0.75% in order to finance the
payment of sales commissions to financial institutions that sell Class B shares,
and to pay for other distribution related expenses. Financial institutions may
compensate their financial advisors with the shareholder servicing and
distribution fees paid to them by the distributor.

PLAN ADMINISTRATION FEE

Class R2, Class R3 and Class R4 pay an annual plan administration services fee
for the provision of various administrative, recordkeeping, communication and
educational services. The fee for Class R2, Class R3 and Class R4 is equal on an
annual basis to 0.25% of assets attributable to the respective class.

DETERMINING WHICH CLASS OF SHARES TO PURCHASE

CLASS A, CLASS B AND CLASS C SHARES

If your investments in RiverSource funds total $100,000 or more, Class A shares
may be the better option because the sales charge is reduced for larger
purchases.

If you invest less than $100,000, consider how long you plan to hold your
shares. Class B shares have a higher annual distribution fee than Class A shares
and a CDSC for six years. Class B shares convert to Class A shares in the ninth
year of ownership. Class B shares purchased through reinvested dividends and
distributions also will convert to Class A shares in the same proportion as the
other Class B shares.

Class C shares also have a higher annual distribution fee than Class A shares.
Class C shares have no sales charge if you hold the shares for longer than one
year. Unlike Class B shares, Class C shares do not convert to Class A. As a
result, you will pay a distribution fee for as long as you hold Class C shares.
If you choose a deferred sales charge option (Class B or Class C), you should
consider the length of time you intend to hold your shares. To help you
determine which investment is best for you, consult your financial institution.

CLASS I SHARES.

The following eligible investors may purchase Class I shares:

- - Any fund distributed by RiverSource Distributors, Inc., if the fund seeks to
  achieve its investment objective by investing primarily in shares of the fund
  and other RiverSource funds.

Class I shares may be purchased, sold or exchanged only through the distributor
or an authorized financial institution.

CLASS R SHARES.

The following eligible institutional investors may purchase Class R2, Class R3,
Class R4 and Class R5 shares:

- - Qualified employee benefit plans.

                                        RIVERSOURCE FUNDS -- PROXY STATEMENT C.5


- - Trust companies or similar institutions, and charitable organizations that
  meet the definition in Section 501(c)(3) of the Internal Revenue Code.

  qualified employee benefit plan described above.

- - State sponsored college savings plans established under Section 529 of the
  Internal Revenue Code.

- - Health Savings Accounts (HSAs) created pursuant to public law 108-173.

Additionally, if approved by the distributor, the following eligible
institutional investors may purchase Class R5 shares:

- - Institutional or corporate accounts above a threshold established by the
  distributor (currently $1 million per fund or $10 million in all RiverSource
  funds).

- - Bank Trusts departments.

Class R shares generally are not available to retail non-retirement accounts,
traditional and Roth IRAs, Coverdell Educational Savings Accounts, SEPs,
SAR-SEPs, SIMPLE IRAs and individual 403(b) plans.

Class R shares may be purchased, sold or exchanged only through the distributor
or an authorized financial institution.

CLASS W SHARES.

The following eligible investors may purchase Class W shares:

- - Investors purchasing through authorized investment programs managed by
  investment professionals, including discretionary managed account programs.

Class W shares may be purchased, sold or exchanged only through the distributor
or an authorized financial institution.

Shares originally purchased in a discretionary managed account may continue to
be held in Class W outside of a discretionary managed account, but no additional
Class W purchases may be made and no exchanges to Class W shares of another fund
may be made outside of a discretionary managed account.

IN ADDITION, FOR CLASS I, CLASS R AND CLASS W SHARES, THE DISTRIBUTOR, IN ITS
SOLE DISCRETION, MAY ACCEPT INVESTMENTS FROM OTHER PURCHASERS NOT LISTED ABOVE.

For more information, see the Merger SAI.

SALES CHARGES

CLASS A -- INITIAL SALES CHARGE ALTERNATIVE

Your purchase price for Class A shares is generally the net asset value (NAV)
plus a front-end sales charge. The distributor receives the sales charge and
re-allows a portion of the sales charge to the financial institution through
which you purchased the shares. The distributor retains the balance of the sales
charge. Sales charges vary depending on the amount of your purchase.

    these percentages.
 ** Purchase price includes the sales charge.
 ***Although there is no sales charge for purchases with a total market value
    over $1,000,000, and therefore no re-allowance, the distributor may pay a
    financial institution the following: a sales commission of up to 1.00% for a
    sale with a total market value of $1,000,000 to $2,999,999; a sales
    commission up to 0.50% for a sale of $3,000,000 to $9,999,999; and a sales
    commission up to 0.25% for a sale of $10,000,000 or more.

 C.6 RIVERSOURCE FUNDS -- PROXY STATEMENT


INITIAL SALES CHARGE -- RIGHTS OF ACCUMULATION. You may be able to reduce the
sales charge on Class A shares, based on the combined market value of your
accounts. The current market values of the following investments are eligible to
be added together for purposes of determining the sales charge on your purchase:

- - Your current investment in a fund; and

- - Previous investments you and members of your primary household group have made
  in Class A, Class B or Class C shares in the fund and other RiverSource funds,
  provided your investment was subject to a sales charge. Your primary household
  group consists of you, your spouse or domestic partner and your unmarried
  children under age 21 sharing a mailing address.

The following accounts are eligible to be included in determining the sales
charge on your purchase:

- - Individual or joint accounts;

- - Roth and traditional IRAs, SEPs, SIMPLEs and TSCAs, provided they are invested
  in Class A, Class B or Class C shares that were subject to a sales charge;

- - UGMA/UTMA accounts for which you, your spouse, or your domestic partner is
  parent or guardian of the minor child;

- - Revocable trust accounts for which you or a member of your primary household
  group, individually, is the beneficial owner/grantor;

- - Accounts held in the name of your, your spouse's, or your domestic partner's
  sole proprietorship or single owner limited liability company or S
  corporation; and

- - Qualified retirement plan assets, provided that you are the sole owner of the
  business sponsoring the plan, are the sole participant (other than a spouse)
  in the plan, and have no intention of adding participants to the plan.

The following accounts are NOT eligible to be included in determining the sales
charge on your purchase:

- - Accounts of pension and retirement plans with multiple participants, such as
  401(k) plans (which are combined to reduce the sales charge for the entire
  pension or retirement plan and therefore are not used to reduce the sales
  charge for your individual accounts);

- - Investments in Class A shares where the sales charge is waived, for example,
  purchases through wrap accounts;

- - Investments in Class D, Class E, Class I, Class R2, Class R3, Class R4, Class
  R5, Class W or Class Y shares;

- - Investments in 529 plans, donor advised funds, variable annuities, variable
  life insurance products, wrap accounts or managed separate accounts; and

- - Charitable and irrevocable trust accounts.

If you purchase RiverSource fund shares through different financial
institutions, and you want to include those assets toward a reduced sales
charge, you must inform your financial institution in writing about the other
accounts when placing your purchase order. Contact your financial institution to
determine what information is required.

Unless you provide your financial institution in writing with information about
all of the accounts that may count toward a sales charge reduction, there can be
no assurance that you will receive all of the reductions for which you may be
eligible. You should request that your financial institution provide this
information to the fund when placing your purchase order.

For more information on rights of accumulation, please see the Merger SAI.

INITIAL SALES CHARGE -- LETTER OF INTENT (LOI). Generally, if you intend to
invest $50,000 or more over a period of 13 months or less, you may be able to
reduce the front-end sales charges for investments in Class A shares by
completing and filing a LOI form. The LOI becomes effective only after the form
is processed in good order by the fund. An LOI can be backdated up to a maximum
of 90 days. If the LOI is backdated, you may include prior investments in Class
A shares that were charged a front-end sales load toward the LOI commitment
amount. If the LOI is backdated, the 13-month period begins on the date of the
earliest purchase included in the LOI.

Holdings More than 90 Days Old. Purchases made more than 90 days before your LOI
is processed by the fund will not be counted toward the commitment amount of the
LOI and cannot be used as the starting point for the LOI. While these purchases
cannot be included in an LOI, they may help you obtain a reduced sales charge on
future purchases as described in "Initial Sales Charge -- Rights of
Accumulation."

Notification Obligation. You must request the reduced sales charge when you buy
shares. If you do not complete and file the LOI form, or do not request the
reduced sales charge at the time of purchase, you will not be eligible for the
reduced sales charge. You should request that your financial institution provide
this information to the fund when placing your purchase order. For more details
on LOIs, please contact your financial institution or see the Merger SAI.

                                        RIVERSOURCE FUNDS -- PROXY STATEMENT C.7

    class of another RiverSource fund;

  - through or under a wrap fee product or other investment product sponsored by

    of the Internal Revenue Code;

- - shareholders whose original purchase was in a Strategist fund merged into a
  RiverSource fund in 2000.

The distributor may, in its sole discretion, authorize the waiver of sales
charges for additional purchases or categories of purchases. Policies related to
reducing or waiving the sales charge may be modified or withdrawn at any time.

Unless you provide your financial institution with information in writing about
all of the factors that may count toward a waiver of the sales charge, there can
be no assurance that you will receive all of the waivers for which you may be
eligible. You should request that your financial institution provide this
information to the fund when placing your purchase order.

Because the current prospectus is available on RiverSource Investment's website
free of charge, RiverSource Investments does not disclose this information
separately on the website.

CLASS B AND CLASS C -- CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE

FOR CLASS B, the CDSC is based on the sale amount and the number of years
between purchase and sale. The following table shows how CDSC percentages on
sales decline:

<Table>
<Caption>
IF THE SALE IS MADE DURING THE:                                 THE CDSC PERCENTAGE RATE IS:*
                                                             
 First year                                                                   5%
 Second year                                                                  4%
 Third year                                                                   4%
 Fourth year                                                                  3%
 Fifth year                                                                   2%
 Sixth year                                                                   1%
 Seventh or eighth year                                                       0%
</Table>

* Because of rounding in the calculation, the portion of the CDSC retained by
  the distributor may vary and the actual CDSC you pay may be more or less than
  the CDSC calculated using these percentages.

Although there is no front-end sales charge when you buy Class B shares, the
distributor pays a sales commission of 4% to financial institutions that sell
Class B shares. A portion of this commission may, in turn, be paid to your
financial advisor. The distributor receives any CDSC imposed when you sell your
Class B shares.

Purchases made prior to May 21, 2005 age on a calendar year basis. Purchases
made beginning May 21, 2005 age on a daily basis. For example, a purchase made
on Nov. 12, 2004 completed its first year on Dec. 31, 2004 under calendar year
aging. However, a purchase made on Nov. 12, 2005 completed its first year on
Nov. 11, 2006 under daily aging.

 C.8 RIVERSOURCE FUNDS -- PROXY STATEMENT


Class B shares purchased prior to May 21, 2005 will convert to Class A shares in
the ninth calendar year of ownership. Class B shares purchased beginning May 21,
2005 will convert to Class A shares one month after the completion of the eighth
year of ownership.

FOR CLASS C, a 1% CDSC may be charged if you sell your shares within one year
after purchase. Although there is no front-end sales charge when you buy Class C
shares, the distributor pays a sales commission of 1% to financial institutions
that sell Class C shares. A portion of this commission may, in turn, be paid to
your financial advisor. The distributor receives any CDSC imposed when you sell
your Class C shares.

For both Class B and Class C, if the amount you sell causes the value of your
investment to fall below the cost of the shares you have purchased, the CDSC
will be based on the lower of the cost of those shares purchased or market
value. Because the CDSC is imposed only on sales that reduce your total purchase
payments, you do not have to pay a CDSC on any amount that represents
appreciation in the value of your shares, income earned by your shares, or
capital gains. In addition, the CDSC on your sale, if any, will be based on your
oldest purchase payment. The CDSC on the next amount sold will be based on the
next oldest purchase payment.

EXAMPLE

Assume you had invested $10,000 in Class B shares and that your investment had
appreciated in value to $12,000 after 3 1/2 years, including reinvested
dividends and capital gain distributions. You could sell up to $2,000 worth of
shares without paying a CDSC ($12,000 current value less $10,000 purchase
amount). If you sold $2,500 worth of shares, the CDSC would apply to the $500
representing part of your original purchase price. The CDSC rate would be 3%
because the sale was made during the fourth year after the purchase.

CDSC -- WAIVERS OF THE CDSC FOR CLASS B SHARES. The CDSC will be waived on sales
of shares:

- - in the event of the shareholder's death;

- - held in trust for an employee benefit plan; or

- - held in IRAs or certain qualified plans, such as Keogh plans, tax-sheltered
  custodial accounts or corporate pension plans, provided that the shareholder
  is:

  - at least 59 1/2 years old AND

  - taking a retirement distribution (if the sale is part of a transfer to an
    IRA or qualified plan, or a custodian-to-custodian transfer, the CDSC will
    not be waived) OR

  - selling under an approved substantially equal periodic payment arrangement.

CDSC -- WAIVERS OF THE CDSC FOR CLASS C SHARES. The CDSC will be waived on sales
of shares in the event of the shareholder's death.

CLASS I, CLASS R2, CLASS R3, CLASS R4, CLASS R5 AND CLASS W -- NO SALES CHARGE.
For Class I, Class R2, Class R3, Class R4, Class R5 and Class W, there is no
initial sales charge or CDSC.

OPENING AN ACCOUNT

Financial institutions are required by law to obtain certain personal
information from each person who opens an account in order to verify the
identity of the person. As a result, when you open an account you will be asked
to provide your name, permanent street address, date of birth, and Social
Security or Employer Identification number. You may also be asked for other
identifying documents or information. If you do not provide this information,
the financial institution through which you are investing in the fund may not be
able to open an account for you. If the financial institution through which you
are investing in the fund is unable to verify your identity, your account may be
closed, or other steps may be taken, as deemed appropriate.

When you buy shares, your order will be priced at the next NAV calculated after
your order is accepted by the fund or an authorized financial institution.

Your financial institution may establish and maintain your account directly or
it may establish and maintain your account with the distributor. The distributor
may appoint servicing agents to accept purchase orders and to accept exchange
(and sale) orders on its behalf. Accounts maintained by the distributor will be
supported by the fund's transfer agent.

METHODS OF PURCHASING SHARES

These methods of purchasing shares apply to Class A, Class B, and Class C
shares.

THROUGH AN ACCOUNT ESTABLISHED WITH YOUR FINANCIAL INSTITUTION

ALL REQUESTSThe financial institution through which you buy shares may have
            different policies not described in this prospectus, including
            different minimum investment amounts and minimum account balances.

EXCHANGES

Generally, you may exchange your fund shares for shares of the same class of any

information on the fund you are exchanging into, including fees and expenses,
read that fund's prospectus carefully. Your exchange will be priced at the next
NAV calculated after your transaction request is received in good order.

MARKET TIMING IS FREQUENT OR SHORT-TERM TRADING BY CERTAIN SHAREHOLDERS INTENDED
TO PROFIT AT THE EXPENSE OF OTHER SHAREHOLDERS BY SELLING SHARES OF A FUND
SHORTLY AFTER PURCHASE. MARKET TIMING MAY ADVERSELY IMPACT A FUND'S PERFORMANCE
BY PREVENTING THE INVESTMENT MANAGER FROM FULLY INVESTING THE ASSETS OF THE
FUND, DILUTING THE VALUE OF SHARES HELD BY LONG-TERM SHAREHOLDERS, OR INCREASING
THE FUND'S TRANSACTION COSTS.

FUNDS THAT INVEST IN SECURITIES THAT TRADE INFREQUENTLY MAY BE VULNERABLE TO
MARKET TIMERS WHO SEEK TO TAKE ADVANTAGE OF INEFFICIENCIES IN THE SECURITIES
MARKETS. FUNDS THAT INVEST IN SECURITIES THAT TRADE ON OVERSEAS SECURITIES
MARKETS MAY BE VULNERABLE TO MARKET TIMERS WHO SEEK TO TAKE ADVANTAGE OF CHANGES
IN THE VALUES OF SECURITIES BETWEEN THE CLOSE OF OVERSEAS MARKETS AND THE CLOSE
OF U.S. MARKETS, WHICH IS GENERALLY THE TIME AT WHICH A FUND'S NAV IS
CALCULATED. TO THE

 C.12 RIVERSOURCE FUNDS -- PROXY STATEMENT


EXTENT THAT A FUND HAS SIGNIFICANT HOLDINGS OF SMALL CAP STOCKS, HIGH YIELD
BONDS, TAX-EXEMPT SECURITIES OR FOREIGN SECURITIES, THE RISKS OF MARKET TIMING
MAY BE GREATER FOR THE FUND THAN FOR OTHER FUNDS. SEE "COMPARISON OF PRINCIPAL
INVESTMENT STRATEGIES SECTION" FOR A DISCUSSION OF THE TYPES OF SECURITIES IN
WHICH YOUR FUND INVESTS.

SEE "VALUING FUND SHARES" FOR A DISCUSSION OF THE RIVERSOURCE FUNDS' POLICY ON
FAIR VALUE PRICING, WHICH IS INTENDED, IN PART, TO REDUCE THE FREQUENCY AND
EFFECT OF MARKET TIMING.

THE RIVERSOURCE FUNDS' BOARDS HAVE ADOPTED A POLICY THAT IS DESIGNED TO DETECT
AND DETER MARKET TIMING THAT MAY BE HARMFUL TO THE FUNDS. EACH FUND SEEKS TO
ENFORCE THIS POLICY THROUGH ITS SERVICE PROVIDERS AS FOLLOWS:

- - The fund tries to distinguish market timing from trading that it believes is
  not harmful, such as periodic rebalancing for purposes of asset allocation or
  dollar cost averaging. Under the fund's procedures, there is no set number of
  transactions in the fund that constitutes market timing. Even one purchase and
  subsequent sale by related accounts may be market timing. Generally, the fund
  seeks to restrict the exchange privilege of an investor who makes more than
  three exchanges into or out of the fund in any 90-day period. Accounts held by
  a retirement plan or a financial institution for the benefit of its
  participants or clients, which typically engage in daily transactions, are not
  subject to this limit, although the fund seeks the assistance of financial
  institutions in applying similar restrictions on the sub-accounts of their
  participants or clients.

- - If an investor's trading activity is determined to be market timing or
  otherwise harmful to existing shareholders, the fund reserves the right to
  modify or discontinue the investor's exchange privilege or reject the
  investor's purchases or exchanges, including purchases or exchanges accepted
  by a financial institution. The fund may treat accounts it believes to be
  under common control as a single account for these purposes, although it may
  not be able to identify all such accounts.

- - Although the fund does not knowingly permit market timing, it cannot guarantee
  that it will be able to identify and restrict all short-term trading activity.
  The fund receives purchase and sale orders through financial institutions
  where market timing activity may not always be successfully detected.

Other exchange policies:

- - Exchanges must be made into the same class of shares of the new fund.

- - Exchanges into RiverSource Tax-Exempt Money Market Fund may be made only from
  Class A shares.

- - If your exchange creates a new account, it must satisfy the minimum investment
  amount for new purchases.

- - Once the fund receives your exchange request, you cannot cancel it.

- - Shares of the new fund may not be used on the same day for another exchange or
  sale.

- - Shares of Class W originally purchased, but no longer held in a discretionary
  managed account, may not be exchanged for Class W shares of another fund. You
  may continue to hold these shares in the fund. Changing your investment to a
  different fund will be treated as a sale and purchase, and you will be subject
  to applicable taxes on the sale and sales charges on the purchase of the new
  fund.

SELLING SHARES

You may sell your shares at any time. The payment will be sent within seven days
after your request is received in good order.

When you sell shares, the amount you receive may be more or less than the amount
you invested. Your sale price will be the next NAV calculated after your request
is received in good order, minus any applicable CDSC.

REPURCHASES. You can change your mind after requesting a sale and use all or
part of the sale proceeds to purchase new shares in the same account, fund and
class from which you sold. If you reinvest in Class A, you will purchase the new
shares at NAV, up to the amount of the sale proceeds, instead of paying a sales
charge on the date of a new purchase. If you reinvest in Class B or Class C, any
CDSC you paid on the amount you are reinvesting also will be reinvested. In
order for you to take advantage of this repurchase waiver, you must notify your
financial institution within 90 days of the date your sale request was
processed. Contact your financial institution for information on required
documentation. The repurchase privilege may be modified or discontinued at any
time and use of this option may have tax consequences.

Each fund reserves the right to redeem in kind.

For more details and a description of other sales policies, please see the
Merger SAI.

VALUING FUND SHARES

For classes of shares sold with an initial sales charge, the public offering or
purchase price is the net asset value plus the sales charge. For funds or
classes of shares sold without an initial sales charge, the public offering
price is the NAV.

Orders in good form are priced at the NAV next determined after you place your
order. Good form or good order means that your instructions have been received
in the form required by the fund. This may include, for example, providing the
fund name and account number, the amount of the transaction and all required
signatures. For more information, contact your financial institution.

                                       RIVERSOURCE FUNDS -- PROXY STATEMENT C.13


The NAV is the value of a single share of a fund. The NAV is determined by
dividing the value of a fund's assets, minus any liabilities, by the number of
shares outstanding. The NAV is calculated as of the close of business on the New
York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time, on each day that
the NYSE is open. Securities are valued primarily on the basis of market
quotations and floating rate loans are valued primarily on the basis of
indicative bids. Both market quotations and indicative bids are obtained from
outside pricing services approved and monitored under procedures adopted by the
Board. Certain short-term securities with maturities of 60 days or less are
valued at amortized cost.

When reliable market quotations or indicative bids are not readily available,
investments are priced at fair value based on procedures adopted by the Board.
These procedures are also used when the value of an investment held by a fund is
materially affected by events that occur after the close of a securities market
but prior to the time as of which the fund's NAV is determined. Valuing
investments at fair value involves reliance on judgment. The fair value of an
investment is likely to differ from any available quoted or published price. To
the extent that a fund has significant holdings of high yield bonds, floating
rate loans, tax-exempt securities, foreign securities or small cap stocks that
may trade infrequently, fair valuation may be used more frequently than for
other funds. The funds use an unaffiliated service provider to assist in
determining fair values for foreign securities.

Foreign investments are valued in U.S. dollars. Some of a fund's securities may
be listed on foreign exchanges that trade on weekends or other days when the
fund does not price its shares. In that event, the NAV of the fund's shares may
change on days when shareholders will not be able to purchase or sell the fund's
shares.

DISTRIBUTIONS AND TAXES

As a shareholder you are entitled to your share of your fund's net income and
net gains. Each fund distributes dividends and capital gains to qualify as a
regulated investment company and to avoid paying corporate income and excise
taxes.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Your fund's net investment income is distributed to you as dividends. Dividends
may be composed of qualifying dividend income, which is eligible for
preferential tax rates under current tax law, as well as other ordinary dividend
income, which may include non-qualifying dividends, interest income and
short-term capital gains. Because of the types of income earned by fixed income
funds, it is unlikely the funds will distribute qualifying dividend income.
Capital gains are realized when a security is sold for a higher price than was
paid for it. Each realized capital gain or loss is long-term or short-term
depending on the length of time the fund held the security. Realized capital
gains and losses offset each other. The fund offsets any net realized capital
gains by any available capital loss carryovers. Net short-term capital gains are
included in net investment income. Net realized long-term capital gains, if any,
are distributed by the end of the calendar year as capital gain distributions.

REINVESTMENTS

Dividends and capital gain distributions are automatically reinvested in
additional shares in the same class of the fund, unless you request
distributions in cash. The financial institution through which you purchased
shares may have different policies.

Distributions are reinvested at the next calculated NAV after the distribution
is paid. If you choose cash distributions, you will receive cash only for
distributions declared after your request has been processed.

TAXES

If you buy shares shortly before the record date of a distribution, you may pay
taxes on money earned by the fund before you were a shareholder. You will pay
the full pre-distribution price for the shares, then receive a portion of your
investment back as a distribution, which may be taxable.

For tax purposes, an exchange is considered a sale and purchase, and may result
in a gain or loss. A sale is a taxable transaction. Generally, if you sell
shares for less than their cost, the difference is a capital loss or if you sell
shares for more than their cost, the difference is a capital gain. Your gain may
be short term (for shares held for one year or less) or long term (for shares
held for more than one year).

You may not create a tax loss, based on paying a sales charge, by exchanging
shares before the 91(st) day after the day of purchase. If you buy Class A
shares and exchange into another fund before the 91(st) day after the day of
purchase, you may not include the sales charge in your calculation of tax gain
or loss on the sale of the first fund you purchased. The sales charge may be
included in the calculation of your tax gain or loss on a subsequent sale of the
second fund you purchased. For more information, see the Merger SAI.

FOR TAXABLE FUNDS. Distributions are subject to federal income tax and may be
subject to state and local taxes in the year they are declared. You must report
distributions on your tax returns, even if they are reinvested in additional
shares.

Distributions of shares not held in IRAs or other retirement accounts are
subject to federal income tax and may be subject to state and local taxes in the
year they are declared. You must report distributions on your tax returns, even
if they are reinvested in additional shares.

 C.14 RIVERSOURCE FUNDS -- PROXY STATEMENT


Income received by a fund may be subject to foreign tax and withholding. Tax
conventions between certain countries and the U.S. may reduce or eliminate these
taxes.

Shares held in an IRA or qualified retirement account are generally subject to
different tax rules. Taking a distribution from your IRA or qualified retirement
plan may subject you to federal taxes, penalties and reporting requirements.
Please consult your tax advisor.

FOR TAX-EXEMPT FUNDS. Dividends distributed from interest earned on tax-exempt
securities (exempt-interest dividends) are exempt from federal income taxes but
may be subject to state and local taxes. Dividends distributed from capital gain
distributions and other income earned are not exempt from federal income taxes.
Distributions are taxable in the year the fund declares them regardless of
whether you take them in cash or reinvest them.

Interest on certain private activity bonds is a preference item for purposes of
the individual and corporate alternative minimum taxes. To the extent the fund
earns such income, it will flow through to its shareholders and may be taxable
to those shareholders who are subject to the alternative minimum tax. See the
Merger SAI for more information.

Because interest on municipal bonds and notes is tax-exempt for federal income
tax purposes, any interest on money you borrow that is used directly or
indirectly to purchase fund shares is not deductible on your federal income tax
return. You should consult a tax advisor regarding its deductibility for state
and local income tax purposes.

REITs often do not provide complete tax information until after the calendar
year-end; generally mid to late January and continuing through early February.
Consequently, if your fund has significant investments in REITs, you may not
receive your Form 1099-DIV until February. Other RiverSource funds tax
statements are mailed in January.

IMPORTANT: This information is a brief and selective summary of some of the tax
rules that apply to an investment in a fund. Because tax matters are highly
individual and complex, you should consult a qualified tax advisor.

GENERAL INFORMATION

AVAILABILITY AND TRANSFERABILITY OF FUND SHARES

Please consult your financial institution to determine availability of
RiverSource funds. Currently, RiverSource funds may be purchased or sold through
affiliated broker-dealers of RiverSource Investments and through certain
unaffiliated financial institutions. If you set up an account at a financial
institution that does not have, and is unable to obtain, a selling agreement
with the distributor of the RiverSource funds, you will not be able to transfer
RiverSource fund holdings to that account. In that event, you must either
maintain your RiverSource fund holdings with your current financial institution,
find another financial institution with a selling agreement, or sell your
shares, paying any applicable CDSC. Please be aware that transactions in taxable
accounts are taxable events and may result in income tax liability.

ADDITIONAL SERVICES AND COMPENSATION

In addition to acting as the fund's investment manager, RiverSource Investments
and its affiliates also receive compensation for providing other services to the
funds.

Administration Services. Ameriprise Financial, 200 Ameriprise Financial Center,
Minneapolis, Minnesota 55474, provides or compensates others to provide
administrative services to the RiverSource funds. These services include
administrative, accounting, treasury, and other services. Fees paid by a fund
for these services are included under "Other expenses" in the expense table
under "Fees and Expenses."

Custody Services. Ameriprise Trust Company, 200 Ameriprise Financial Center,
Minneapolis, Minnesota 55474 (the custodian or Ameriprise Trust Company),
provides custody services to all but a limited number of the RiverSource funds,
for which U.S. Bank National Association provides custody services. In addition,
Ameriprise Trust Company is paid for certain transaction fees and out-of-pocket
expenses incurred while providing services to the funds. Fees paid by a fund for
these services are included under "Other expenses" in the expense table under
"Fees and Expenses."

Distribution and Shareholder Services. RiverSource Distributors, Inc., 50611
Ameriprise Financial Center, Minneapolis, Minnesota 55474 (the distributor or
RiverSource Distributors), provides underwriting and distribution services to
the RiverSource funds. Under the Distribution Agreement and related distribution
and shareholder servicing plans, the distributor receives distribution and
shareholder servicing fees. The distributor may retain a portion of these fees
to support its distribution and shareholder servicing activity. The distributor
re-allows the remainder of these fees (or the full fee) to the financial
institutions that sell fund shares and provide services to shareholders. Fees
paid by a fund for these services are set forth under "Distribution (12b-1)
fees" in the expense table under "Fees and Expenses." More information on how
these fees are used is set forth under "Investment Options -- Classes of Shares"
in Exhibit C and in the Merger SAI. The distributor also administers any sales
charges paid by an investor at the time of purchase or at the time of sale. See
"Shareholder Fees (fees paid directly from your investment)" under "Fees and
Expenses" for the scheduled sales charge of each share class. See "Buying and
Selling

                                       RIVERSOURCE FUNDS -- PROXY STATEMENT C.15


Shares: Sales Charges" for variations in the scheduled sales charges, and for
how these sales charges are used by the distributor. See "Comparison of Other
Investment Strategies and Risks" for the RiverSource funds' policy regarding
directed brokerage.

Plan Administration Services. Under a Plan Administration Services Agreement the
fund pays for plan administration services, including services such as
implementation and conversion services, account set-up and maintenance,
reconciliation and account recordkeeping, education services and administration
to various plan types, including 529 plans, retirement plans and Health Savings
Accounts (HSAs). Fees paid by a fund for these services are included under
"Other expenses" in the expense table under "Fees and Expenses."

Transfer Agency Services. RiverSource Service Corporation, 734 Ameriprise
Financial Center, Minneapolis, Minnesota 55474 (the transfer agent or
RiverSource Service Corporation), provides or compensates others to provide
transfer agency services to the RiverSource funds. The RiverSource funds pay the
transfer agent a fee that varies by class, as set forth in the SAI, and
reimburses the transfer agent for its out-of-pocket expenses incurred while
providing these transfer agency services to the funds. Fees paid by a fund for
these services are included under "Other expenses" in the expense table under
"Fees and Expenses." RiverSource Service Corporation pays a portion of these
fees to financial institutions that provide sub-recordkeeping and other services
to fund shareholders. The Merger SAI provides additional information about the
services provided and the fee schedules for the transfer agent agreements.

PAYMENTS TO FINANCIAL INSTITUTIONS

RiverSource Investments and its affiliates may make or support additional cash
payments out of their own resources to financial institutions, including
inter-company allocation of resources to affiliated broker-dealers such as
Ameriprise Financial Services (and its licensed representatives), in connection
with selling fund shares or providing services to the fund or its shareholders.
These inter-company allocations may include payment as compensation to employees
of RiverSource Investments who are licensed by Ameriprise Financial Services, in
respect of certain sales and solicitation activity on behalf of the funds. These
payments and inter-company allocations are in addition to any 12b-1 distribution
and/or shareholder service fees or other amounts paid by the fund to the
distributor under distribution and shareholder servicing plans, or paid by the
fund to the transfer agent under its transfer agency agreement or plan
administration agreement, which fees may be used by these entities to support
shareholder account maintenance, sub-accounting, recordkeeping or other services
provided directly by the financial institution to shareholders or 529 and
retirement plans and the plan participants. In exchange for these payments and
inter-company allocations, RiverSource Investments and its affiliates may
receive preferred access to registered representatives of a financial
institution (for example, the ability to make presentations in branch offices or
at conferences) or preferred access to customers of the financial institution
(for example, the ability to advertise or directly interact with the financial
institution's customers in order to sell the fund). These arrangements are
sometimes referred to as "revenue sharing payments." In some cases, these
arrangements may create an incentive for a financial institution or its
representatives to recommend or sell shares of a fund and may create a conflict
of interest between a financial institution's financial interest and its duties
to its customers. Please contact the financial institution through which you are
purchasing shares of the fund for details about any payments it may receive in
connection with the solicitation and sale of fund shares or providing services
to the fund or its shareholders. These payments and inter-company allocations
are usually calculated based on a percentage of fund sales and/or as a
percentage of fund assets attributable to a particular financial institution.
These payments may also be negotiated based on other criteria or factors
including, but not limited to, the financial institution's affiliation with the
investment manager, its reputation in the industry, its ability to attract and
retain assets, its access to target markets, its customer relationships and the
scope and quality of services it provides. The amount of payment or
inter-company allocation may vary by financial institution and by type of sale
(e.g., purchases of different share classes or purchases of the fund through a
qualified plan or through a wrap program), and may be significant.

From time to time, RiverSource Investments and its affiliates may make other
reimbursements or payments to financial institutions or their representatives
including non-cash compensation, in the form of gifts of nominal value,
occasional meals, tickets, or other entertainment, support for due diligence
trips, training and educational meetings or conference sponsorships, support for
recognition programs, and other forms of non-cash compensation permissible under
regulations to which these financial institutions and their representatives are
subject.

ADDITIONAL MANAGEMENT INFORMATION

MANAGER OF MANAGERS EXEMPTION. The RiverSource funds have received an order from
the Securities and Exchange Commission that permits RiverSource Investments,
subject to the approval of the Board, to appoint a subadviser or change the
terms of a subadvisory agreement for a fund without first obtaining shareholder
approval. The order permits the fund to add or change unaffiliated subadvisers
or change the fees paid to subadvisers from time to time without the expense and
delays associated with obtaining shareholder approval of the change.

Before certain fixed income funds may rely on the order, holders of a majority
of the fund's outstanding voting securities will need to approve operating the
fund in this manner. There is no assurance shareholder approval will be
received, and no changes will be made without shareholder approval until that
time. For more information, see the Merger SAI.

 C.16 RIVERSOURCE FUNDS -- PROXY STATEMENT


RiverSource Investments or its affiliates may have other relationships,
including significant financial relationships, with current or potential
subadvisers or their affiliates, which may create a conflict of interest. In
making recommendations to the Board to appoint or to change a subadviser, or to
change the terms of a subadvisory agreement, RiverSource Investments does not
consider any other relationship it or its affiliates may have with a subadviser,
and RiverSource Investments discloses the nature of any material relationships
it has with a subadviser to the Board.

AFFILIATED PRODUCTS. RiverSource Investments also serves as investment manager
to RiverSource funds that provide asset-allocation services to shareholders by
investing in shares of other RiverSource funds (Funds of Funds) and to
discretionary managed accounts (collectively referred to as "affiliated
products"). A fund may experience relatively large purchases or redemptions from
the affiliated products. Although RiverSource Investments seeks to minimize the
impact of these transactions by structuring them over a reasonable period of
time or through other measures, a fund may experience increased expenses as it
buys and sells securities to manage transactions for the affiliated products. In
addition, because the affiliated products may own a substantial portion of a
fund, a redemption by one or more affiliated product could cause a fund's
expense ratio to increase as the fund's fixed costs would be spread over a
smaller asset base. RiverSource Investments monitors expense levels and is
committed to offering funds that are competitively priced. RiverSource
Investments will report to the Board on the steps it has taken to manage any
potential conflicts.

CASH RESERVES. A fund may invest its daily cash balance in RiverSource
Short-Term Cash Fund (Short-Term Cash Fund), a money market fund established for
the exclusive use of the RiverSource funds and other institutional clients of
RiverSource Investments. While Short-Term Cash Fund does not pay an advisory fee
to RiverSource Investments, it does incur other expenses, and is expected to
operate at a very low expense ratio. A fund will invest in Short-Term Cash Fund
only to the extent it is consistent with the fund's investment objectives and
policies. Short-Term Cash Fund is not insured or guaranteed by the FDIC or any
other government agency.

FUND HOLDINGS DISCLOSURE. The Board has adopted policies and procedures that
govern the timing and circumstances of disclosure to shareholders and third
parties of information regarding the securities owned by a fund. A description
of these policies and procedures is included in the Merger SAI.

LEGAL PROCEEDINGS. Ameriprise Financial and certain of its affiliates have
historically been involved in a number of legal, arbitration and regulatory
proceedings, including routine litigation, class actions, and governmental
actions, concerning matters arising in connection with the conduct of their
business activities. Ameriprise Financial believes that the fund is not
currently the subject of, and that neither Ameriprise Financial nor any of its
affiliates are the subject of, any pending legal, arbitration or regulatory
proceedings that are likely to have a material adverse effect on the fund or the
ability of Ameriprise Financial or its affiliates to perform under their
contracts with the fund. Information regarding certain pending and settled legal
proceedings may be found in the Fund's shareholder reports and in the SAI.
Additionally, Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission on legal and
regulatory matters that relate to Ameriprise Financial and its affiliates.
Copies of these filings may be obtained by accessing the SEC website at
www.sec.gov.

HERE IS A BRIEF OVERVIEW OF THE CHANGES BEING RECOMMENDED FOR YOUR RIVERSOURCE
FUND. WE ENCOURAGE YOU TO READ THE FULL TEXT OF THE ENCLOSED PROXY STATEMENT.

Q: WHY AM I BEING ASKED TO VOTE?

Mutual funds are required to get shareholders' approval for certain kinds of
changes, like the ones included in this proxy statement.

Q: IS MY VOTE IMPORTANT?

Absolutely! While the Board of each RiverSource Fund has reviewed these changes
and recommends you approve them, you have the right to voice your opinion. Until
a Fund is sure that a quorum has been reached, it will continue to contact
shareholders asking them to vote.

Q: WHAT AM I BEING ASKED TO VOTE ON?

Shareholders are being asked to vote on:

- - The merger (a "Reorganization") of one or more of several RiverSource Funds
  (each a "Selling Fund" and together, the "Selling Funds") into a corresponding
  RiverSource Fund (each a "Buying Fund" and together, the "Buying Funds") as
  noted in the table below:

<Table>
<Caption>

                        SELLING FUND                                                  BUYING FUND
                                                           
 RiverSource Core Bond Fund                                   RiverSource Diversified Bond Fund
 RiverSource Fundamental Growth Fund                          RiverSource Growth Fund
 RiverSource International Equity Fund                        RiverSource Disciplined International Equity Fund
 RiverSource Massachusetts Tax-Exempt Fund                    RiverSource Tax-Exempt High Income Fund
 RiverSource Michigan Tax-Exempt Fund                         RiverSource Tax-Exempt High Income Fund
 RiverSource Ohio Tax-Exempt Fund                             RiverSource Tax-Exempt High Income Fund
 RiverSource Value Fund                                       RiverSource Diversified Equity Income Fund
</Table>

 If the Reorganization of your Selling Fund is approved by shareholders and the
 other closing conditions are met, shares of the Selling Fund will, in effect,
 be converted into shares of the Buying Fund with the same aggregate net asset
 value as Selling Fund shares at the time of the Reorganization. (Selling Funds
 and Buying Funds may be individually or collectively referred to as a "Fund" or
 the "Funds".)

- - With respect to RiverSource Minnesota Tax-Exempt Fund only ("Minnesota
  Tax-Exempt Fund"), the restoration of the fund's former status as
  "non-diversified."

We encourage you to read the full text of the proxy statement to obtain a more
detailed understanding of the issues.


Q: WHY IS THE REORGANIZATION BEING PROPOSED?

The Reorganization of each Selling Fund into the respective Buying Fund would
result in a larger combined fund with the same or similar investment objectives,
principal investment strategies and investment policies which will allow for
more focused distribution, potentially increasing sales and economies of scale.
Additionally, following the Reorganization, for nearly all classes of shares of
the larger combined fund, expenses will be the same or lower than expenses would
have been for the Selling Fund.

Q: IF APPROVED, WHEN WILL THE REORGANIZATION HAPPEN?

If shareholders approve the Reorganization, it is expected to take place in the
first quarter of 2008.

Q: WHAT CHANGE IS PROPOSED FOR MINNESOTA TAX-EXEMPT FUND?

The Board of RiverSource Special Tax-Exempt Series Trust has approved, and
recommends that shareholders approve, a proposal to change the classification of
Minnesota Tax-Exempt Fund from a "diversified" fund back to a "non-diversified"
fund (its original classification). This would permit Minnesota Tax-Exempt Fund
to invest more of its assets in the securities of fewer issuers.

Q. IF APPROVED, WHEN WILL THE CHANGE TAKE EFFECT?

If shareholders of Minnesota Tax-Exempt Fund approve the proposed change of its
status, the fund will have the ability to act as a "non-diversified" fund
immediately after the shareholder meeting.

Q: HOW DOES THE BOARD RECOMMEND THAT I VOTE?

After careful consideration, the Board of each RiverSource Fund recommends that
you vote FOR each proposal.

Q: HOW DO I VOTE?

You can vote in one of four ways:

- - By mail with the enclosed proxy card

- - By telephone

- - By web site

- - In person at the meeting

Please refer to the enclosed proxy card for the telephone number and internet
address.

Q: WHOM SHOULD I CALL IF I HAVE QUESTIONS?

If you have questions about any of the proposals described in the proxy
statement or about voting procedures, please call toll free at (866) 438-8932.

and asset-backed securities.

Under the proposed Agreement and Plan of Reorganization, Class A shares of the

RiverSource Core Bond Fund would be exchanged for Class I shares of the

NOTES TO PRO FORMA FINANCIAL STATEMENTS
(Unaudited as to Aug. 31, 2007)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments

securities including securities issued by the U.S. government, corporate bonds
and mortgage- and asset-backed securities.

RiverSource Core Bond Fund invests primarily in securities like those included
in the Lehman Brothers Aggregate Bond Index (Index), which are investment grade
and denominated in U.S. dollars. The Index includes securities issued by the
U.S. government, corporate bonds and mortgage- and asset-backed securities.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of RiverSource Core Bond Fund in exchange for Class A, B, C, I, R2,
R3, R4, R5 and W shares of RiverSource Diversified Bond Fund under U.S.
generally accepted accounting principles. The pro forma statements reflect
estimates for the combined RiverSource Diversified Bond Fund based on the

to reflect current fees.

The pro forma combining statements should be read in conjunction with the
historical financial statements of the funds incorporated by reference in the

</Table>



   (A) Securities are valued by procedures described in Note 1 to the financial
       statements in the annual report.

   (B) Non-income producing. For long-term debt securities, item identified is
       in default as to payment of interest and/or principal.

   (C) Foreign security values are stated in U.S. dollars. For debt securities,
       principal amounts are denominated in U.S. dollar currency unless
       otherwise noted. At Aug. 31, 2007, the value of foreign securities
       represented 4.2% of net assets.

   (D) Represents a security sold under Rule 144A, which is exempt from
       registration under the Securities Act of 1933, as amended. This security
       has been determined to be liquid under guidelines established by the
       Fund's Board of Directors. These securities may be resold in transactions
       exempt from registration, normally to qualified institutional buyers. At
       Aug. 31, 2007, the value of these securities amounted to $157,766,931 or
       4.8% or net assets.

   (E)  The following abbreviations are used in the portfolio security
        descriptions to identify the insurer of the issue:
               AMBAC -- Ambac Assurance Corporation
               MBIA -- MBIA Insurance Corporation

   (F) Mortgage-backed securities represent direct or indirect participations
       in, or are secured by and payable from, mortgage loans secured by real
       property, and include single- and multi-class pass-through securities and
       collateralized mortgage obligations. These securities may be issued or
       guaranteed by U.S. government agencies or instrumentalities, or by
       private issuers, generally originators and investors in mortgage loans,
       including savings associations, mortgage bankers, commercial banks,
       investment bankers and special purpose entities. The maturity dates shown
       represent the original maturity of the underlying obligation. Actual
       maturity may vary based upon prepayment activity on these obligations.
       Unless otherwise noted, the coupon rates presented are fixed rates.

   (G) Interest only represents securities that entitle holders to receive only
       interest payments on the underlying mortgages. The yield to maturity of
       an interest only is extremely sensitive to the rate of principal payments
       on the underlying mortgage assets. A rapid (slow) rate of principal
       repayments may have an adverse (positive) effect on yield to maturity.
       The principal amount shown is the notional amount of the underlying
       mortgages. Interest rate disclosed represents yield based upon the
       estimated timing and amount of future cash flows at Aug. 31, 2007.

   (H) Principal only represents securities that entitle holders to receive only
       principal payments on the underlying mortgages. The yield to maturity of
       a principal only is sensitive to the rate of principal payments on the
       underlying mortgage assets. A slow (rapid) rate of principal repayments
       may have an adverse (positive) effect on yield to maturity. Interest rate
       disclosed represents yield based upon the estimated timing of future cash
       flows at Aug. 31, 2007.

   (I) Interest rate varies either based on a predetermined schedule or to
       reflect current market conditions; rate shown is the effective rate on
       Aug.  31, 2007.

   (J) At Aug. 31, 2007, the cost of securities purchased, including interest
       purchased, on a when-issued and/or other forward-commitment basis was
       $306,996,929.

   (K) Adjustable rate mortgage; interest rate varies to reflect current market
       conditions; rate shown is the effective rate on Aug. 31, 2007.

   (L) Senior loans have rates of interest that float periodically based
       primarily on the London Interbank Offered Rate ("LIBOR") and other short-
       term rates. Remaining maturities of senior loans may be less than the
       stated maturities shown as a result of contractual or optional
       prepayments by the borrower. Such prepayments cannot be predicted with
       certainty.

RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND (BUYING FUND)

RIVERSOURCE INTERNATIONAL EQUITY FUND (SELLING FUND)

NOTES TO PRO FORMA FINANCIAL STATEMENTS

(Unaudited as to April 30, 2007)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the two funds at and for the 12-
month period ending April 30, 2007. These statements have been derived from
financial statements prepared for the RiverSource Disciplined International
Equity Fund and RiverSource International Equity Fund as of April 30, 2007.

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments
of each Fund are as follows:

RiverSource Disciplined International Equity Fund and RiverSource International
Equity Fund invest primarily in equity securities of foreign issuers or in
instruments that provide exposure to foreign equity markets.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of RiverSource International Equity Fund in exchange for Class A, B,
C, I and R4 shares of RiverSource Disciplined International Equity Fund under
U.S. generally accepted accounting principles. The pro forma statements reflect
estimates for the combined RiverSource Disciplined International Equity Fund
based on the increased asset level of the merger and associated economies of
scale, adjusted to reflect current fees.

The pro forma combining statements should be read in conjunction with the
historical financial statements of the funds incorporated by reference in the
Statement of Additional Information.

The pro forma statement of operations give effect to the proposed transaction on
the historical operations of the accounting survivor, RiverSource Disciplined

of the year presented.

2. PRO FORMA ADJUSTMENTS

    net assets as of April 30, 2007 and the RiverSource Disciplined
    International Equity Fund PIA rate.

(b) To adjust for closed account fees for each RiverSource International Equity
    Fund shareholder account that will be closed on the system as a result of
    this merger.

(c) To reflect the elimination of the service fee for Class R4.

(d) To reflect the change in administrative services fees due to the
    Reorganization.

(e) To reflect the reduction in the registration fees due to the Reorganization.

    resulting from the reorganization per the agreement by RiverSource
    Investments, LLC and its affiliates to waive certain fees and absorb certain
    expenses following the merger.


                                                                             31

PART C. OTHER INFORMATION

Item 15. Indemnification

The Articles of Incorporation of the registrant provide that the Fund shall
indemnify any person who was or is a party or is threatened to be made a party,
by reason of the fact that she or he is or was a director, officer, employee or
agent of the Fund, or is or was serving at the request of the Fund as a
director, officer, employee or agent of another company, partnership, joint
venture, trust or other enterprise, to any threatened, pending or completed
action, suit or proceeding, wherever brought, and the Fund may purchase
liability insurance and advance legal expenses, all to the fullest extent
permitted by the laws of the State of Minnesota, as now existing or hereafter
amended. The By-laws of the registrant provide that present or former directors
or officers of the Fund made or threatened to be made a party to or involved
(including as a witness) in an actual or threatened action, suit or proceeding
shall be indemnified by the Fund to the full extent authorized by the Minnesota
Business Corporation Act, all as more fully set forth in the By-laws filed as an
exhibit to this registration statement.

Insofar as indemnification for liability arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Any indemnification hereunder shall not be exclusive of any other rights of
indemnification to which the directors, officers, employees or agents might
otherwise be entitled. No indemnification shall be made in violation of the
Investment Company Act of 1940.
