                               DATED DEC. 16, 2005

This document is a proxy statement for Selective and a prospectus for
Diversified Bond (each individually a "Fund" and collectively the "Funds"). It
contains the information you should know before voting on the proposals. Please
read it carefully and keep it for future reference. The address of each of the
Funds is 901 Marquette Avenue South, Suite 2810, Minneapolis, MN 55402-3268. The
phone number for each of the Funds is (612) 330-9283.

The following information describes the proposed reorganization of the Selling
Fund into the Buying Fund (the "Reorganization").

HOW THE REORGANIZATION WILL WORK

- -  The Selling Fund will transfer all of its assets to the Buying Fund. The
   Buying Fund will assume the Selling Fund's liabilities.

- -  The Buying Fund will issue shares of Classes A, B, C, I and Y to the Selling
   Fund in an amount equal to the value of the assets of Classes A, B, C, I and
   Y that it receives from the Selling Fund, less the liabilities it assumes.
   These shares will be distributed to the Selling Fund's shareholders in
   proportion to their holdings in the Selling Fund. Selling Fund shareholders
   will not pay any sales charge in connection with this distribution of shares.

FUND INVESTMENT OBJECTIVES

The investment objective for each of the Funds is as follows:

   SELLING FUND:  The Fund seeks to provide shareholders with current income and
                  preservation of capital.

   BUYING FUND:   The 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.

Please note that the Fund is not a bank deposit, is not federally insured, is
not endorsed by any bank or government agency and is not guaranteed to achieve
its investment objective.

As with all mutual funds, the Securities and Exchange Commission (the "SEC") has
not approved or disapproved these securities or passed on the adequacy of this

SECTION A -- FUND PROPOSALS

PROPOSAL 1. APPROVE OR REJECT THE AGREEMENT AND PLAN OF REORGANIZATION

SUMMARY

This proxy statement/prospectus is being used by the Board of the Selling Fund
to solicit proxies to vote at a meeting of shareholders. Shareholders will
consider a proposal to approve the Agreement providing for the Reorganization of
the Selling Fund into the Buying Fund. A form of the Agreement is included in
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 the summary.

HOW THE REORGANIZATION WILL WORK

- -  The Selling Fund will transfer all of its assets to the Buying Fund. The
   Buying Fund will assume the Selling Fund's stated liabilities.

- -  The Buying Fund will issue shares of Classes A, B, C, I and Y to the Selling
   Fund in an amount equal to the value of the assets of Classes A, B, C, I and
   Y that it receives from the Selling Fund, less the liabilities it assumes.
   These shares will be distributed to the Selling Fund's shareholders in
   proportion to their holdings in the Selling Fund.

- -  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.

COMPARISON OF THE SELLING FUND AND THE BUYING FUND

Both the Selling Fund and the Buying Fund:

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

- -  Have RiverSource Investments, LLC (the "investment manager" or "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.

- -  Have different classes of shares: Classes A, B, C, I and Y.

COMPARISON OF INVESTMENT OBJECTIVES

The investment objectives for the Funds are as follows:

   SELLING FUND:  The Fund seeks to provide shareholders with current income and
                  preservation of capital.

   BUYING FUND:   The 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 INVESTMENT STRATEGIES

SELECTIVE:

The Fund's assets are primarily invested in debt obligations. Although the Fund
is not an index fund, under normal market conditions, it will invest 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.

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

- -  Reviewing the stage and direction of economic business cycles. Depending on
   the stage of the business cycle, the investment manager will choose debt
   obligations from the following market sectors: government securities,
   corporate securities, and asset-backed securities.

- -  Reviewing credit characteristics and interest rate outlook.

- -  Targeting an average portfolio duration within one year of the duration of
   the Index which, as of Aug. 31, 2005, was 4.26 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%.

- -  Identifying and buying securities that:

   -  are medium and high quality (investment grade),

   -  have maturities that complement the investment manager's expectations for
      long-term and short-term interest rates, and

   -  are expected to outperform other market sectors. In this analysis, the
      investment manager will take risk factors into account (for example,
      whether money has been set aside to cover the cost of principal and
      interest payments).

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                        8
<Page>

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

- -  The interest rate or economic outlook changes.

- -  A sector or industry is experiencing change.

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

- -  The security is overvalued relative to alternative investments.

- -  The investment manager identifies a more attractive opportunity.

DIVERSIFIED BOND:

Under normal market conditions, the 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 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 to achieve higher yield and/or capital appreciation by
buying lower-quality (junk) bonds. The Fund may invest up to 15% 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 the 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.

- -  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, 2005, was 4.26 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.

BOTH FUNDS:

- -  UNUSUAL MARKET CONDITIONS. During unusual market conditions, each of the
   Funds 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.

- -  OTHER INVESTMENT STRATEGIES. In addition to the principal investment
   strategies previously described, each Fund may invest in other securities and
   may use other investment strategies that are not principal investment
   strategies. Additionally, each 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.

COMPARISON OF FUNDAMENTAL POLICIES

The Buying Fund will vote on changes to the fundamental policies for the Buying
Fund at a meeting scheduled to be held on the same day as the Selling Fund
shareholder meeting. The proposed changes are shown in Exhibit B. If all of the
proposed changes to the Buying Fund's fundamental policies are approved, the
differences in investment policies will be as follows:

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       10

Both Funds have substantially similar fundamental investment policies. The
Buying Fund has a policy permitting borrowing money for temporary purposes in an
amount not exceeding one-third of the market value of its total assets. The
Selling Fund has a similar policy that applies to money or property and permits
borrowing only for extraordinary or emergency purposes. The Selling Fund has a
policy prohibiting the issuing of senior securities, except as permitted under
the 1940 Act. Even though this is not stated as a fundamental policy of the
Buying Fund, the Fund is nonetheless subject to that restriction under the
provisions of the 1940 Act.

The Buying Fund has a policy permitting the Fund to lend fund securities and
participate in an interfund lending program up to 33-1/3% of the value of the
fund's total assets. This policy does not prohibit the Buying Fund from
purchasing money market, loan participation or other debt securities, or from
entering into repurchase agreements. The Selling Fund has a policy permitting
the Selling Fund to lend fund securities up to 30% of its net assets. In
addition, the Selling Fund has a policy that it may make cash loans up to 5% of
its total assets. The Selling Fund has a policy prohibiting loans to the
investment manager, its board members and officers and to the board members and
officers of the Selling Fund.

The Buying Fund has a policy that it will not purchase more than 10% of the
outstanding voting securities of an issuer, except up to 25% of its total assets
may be invested without regard to this 10% limitation. The Selling Fund has a
similar policy, but does not have the 25% exception. The Buying Fund has a
policy that it will not invest more than 5% of its total assets in securities of
any one company, government, or political subdivision thereof, except the
limitation will not apply to investments in securities issued by the U.S.
government, its agencies, or instrumentalities, or other investment companies,
and except that up to 25% of its total assets may be invested without regard to
this 5% limitation. The Selling Fund has a similar policy, but does not include
other investment companies in the exception.

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

RISK FACTORS

The principal risks associated with an investment in the Fund are shown below.

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 -- SELLING FUND. 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.

- -  CREDIT RISK -- BUYING FUND. 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 company 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.

- -  INTEREST RATE RISK. 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.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       12
<Page>

- -  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. 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.

TAX CONSEQUENCES

The Reorganization is expected to be tax-free for federal income tax purposes
and will not take place unless the Selling Fund and the 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 the Reorganization. However, the
Reorganization will end the tax year of the Selling Fund, and so it may
accelerate distributions from the Selling Fund for its short tax year ending on
the date of the Reorganization to shareholders. At any time prior to the
consummation of the Reorganization a shareholder may redeem shares. This would
likely result in recognition of gain or loss to the shareholder for federal
income tax purposes.

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 Reorganization."

NOTES TO ANNUAL FUND OPERATING EXPENSES.

(a) This charge may be reduced depending on the value of your total investments
    in RiverSource funds.

(b) For Class A purchases over $1,000,000 on which no sales charge is assessed,
    a 1% sales charge may apply if you sell your shares within one year after
    purchase.

(c) Selective is a feeder fund that is part of a master/feeder structure. For
    Selective, both in this table and the following example, fund operating
    expenses, include expenses charged by both the Fund and its master
    portfolio.

(d) The management fee ratio is the actual ratio as of May 31, 2005. If this
    merger is not approved, there is a separate proposal to modify the
    management fee schedule. The estimated management fee ratio under this
    proposed schedule based on average net assets as of May 31, 2005 is .48%.

(e) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee and other nonadvisory expenses and, for Class Y shares, a
    shareholder service fee. The other expense ratios shown in this chart have
    been adjusted to reflect the new administrative services fee that went into
    effect in October 2005.

(f) For Selective, the investment manager and its affiliates have contractually
    agreed to waive certain fees and to absorb certain expenses until May 31,
    2006, unless sooner terminated at the discretion of the Fund's Board. Any
    amounts waived will not be reimbursed by the Fund. Under this agreement, net
    expenses will not exceed 0.89% for Class A, 1.64% for Class B, 1.64% for
    Class C, 0.59% for Class I and 0.72% for Class Y. For Diversified Bond, the
    investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Aug. 31, 2006, unless
    sooner terminated at the discretion of the Fund's Board. Any amounts waived
    will not be reimbursed by the Fund. Under this agreement, total expenses
    will not exceed 0.89% for Class A, 1.65% for Class B, 1.66% for Class C,
    0.59% for Class I and 0.73% for Class Y.

(g) The management fee ratio shown reflects what the ratio would be under the
    proposed management fee schedule based on average net assets as of Aug. 31,
    2005.

(h) If shareholders approve the Reorganization, the investment manager and its
    affiliates have contractually agreed to waive certain fees and to absorb
    certain expenses until Aug. 31, 2006, unless sooner terminated at the
    discretion of the Fund's Board. Under this agreement, total expenses will
    not exceed 0.89% for Class A, 1.65% for Class B, 1.66% for Class C, 0.59%
    for Class I and 0.73% for Class Y.

EXAMPLE: 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
indicated 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:

THE REORGANIZATION

TERMS OF THE REORGANIZATION

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

- -  The Reorganization is scheduled to occur on the first day that the New York
   Stock Exchange is open for business following shareholder approval and
   receipt of any necessary regulatory approvals, but may occur on any later
   date agreed to by 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 the Selling Fund's stated liabilities.

- -  The Buying Fund will issue Class A, B, C, I and Y shares to the Selling Fund
   in an amount equal to the value of the assets of Classes A, B, C, I and Y
   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 or Y 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 closing date.

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

CONDITIONS TO CLOSING THE REORGANIZATION

The completion of the 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 the
   proposed Reorganization will result in no gain or loss being recognized by
   any shareholder.

TERMINATION OF THE AGREEMENT

The Agreement and the transactions contemplated by it may be terminated and
abandoned 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 the Board members, officers or shareholders of the Selling Corporation or of
the Buying Corporation.

TAX STATUS OF THE REORGANIZATION

The Reorganization is expected to be tax-free for federal income tax purposes
and will not take place 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"):

- -  The transfer of the Selling Fund's assets to the Buying Fund in exchange for
   Class A, B, C, I and Y shares of the Buying Fund and the assumption of the
   Selling Fund's liabilities, followed by the distribution of those Class A, B,
   C, I and Y shares 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 and Y shares 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 or Y
   shares of the Selling Fund solely for Buying Fund Class A, B, C, I or Y
   shares as part of the Reorganization.

- -  Under Section 358 of the Code, the aggregate basis of the Class A, B, C, I or
   Y shares 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 or Y shares of the Selling Fund exchanged therefor.

- -  Under Section 1223(1) of the Code, the holding period for the Class A, B, C,
   I or Y shares 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 or Y shares 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.

                                       19
<Page>

- -  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 and Y shares 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 receives 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.

Tax counsel 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.

Prior to the closing of the 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 tax 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 a 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.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       20
<Page>

The Buying Fund's ability to carry forward the pre-acquisition losses of the
Selling Fund and use them to offset future gains will technically be limited as
a result of the Reorganization due to the effect of loss limitation rules under
applicable tax law. The effect of such limitation will depend on the losses and
gains in each fund at the time of the Reorganization. For example, based on data
as of Aug. 31, 2005, the Selling Fund and the Buying Fund had pre-Reorganization
"net losses" (i.e., capital loss carryforwards as of its last fiscal year end as
adjusted by year-to-date realized gains or losses and all net unrealized gains)
equal to 3.15% and 4.28% of each fund's net assets, respectively. If the
Reorganization had occurred on Aug. 31, 2005, the combined fund would have had
net losses equal to 3.61% of its net assets (due to the Buying Fund's relatively
larger losses).

In addition, for five years after the closing date, the combined fund will not
be allowed to offset any 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 the
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.

This description of the federal income tax consequences of the Reorganization
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 REORGANIZATION AND BOARD DELIBERATIONS

The Board believes that the proposed Reorganization will be advantageous to
Selling Fund shareholders for several reasons. The Board considered the
following matters, among others, in approving the Reorganization.

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

- -  TAX CONSEQUENCES. The Board considered the tax-free nature of the
   Reorganization.

- -  CONTINUITY OF INVESTMENT. The Board took into account the fact that,
   following the Reorganization, shareholders of the Selling Fund will be
   invested in a fund holding a similar investment securities portfolio, with
   similar investment objectives, policies, and restrictions.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       21
<Page>

- -  EXPENSE RATIOS. The Board considered the relative expenses of the Funds.
   Following the Reorganization, the expense ratio for the combined Fund,
   adjusted to reflect current fees, before giving effect to any fee waivers or
   expense caps by the investment manager or its affiliates is expected to be
   lower than the expense ratio of the Selling Fund. Thus, Selling Fund
   shareholders are expected to experience lower per share fixed costs by
   holding shares of the Buying Fund than they would if they continued to hold
   shares in the Selling Fund. In addition, the Selling Fund is less than half
   the size of the Buying Fund and has been losing assets. The Board considered
   that higher aggregate net assets resulting from the Reorganization and the
   opportunity for net cash inflows may reduce the risk that, if net assets of
   the Selling Fund fail to grow, or diminish, its total expense ratio could
   rise as fixed expenses become a larger percentage of net assets.

- -  ECONOMIES OF SCALE. The Board considered the advantage of combining Funds
   that share similar investment objectives, styles and holdings. The Board
   believes that by combining the Funds, the shareholders continue to have
   available to them a Fund with a similar investment objective, but can at the
   same time take advantage of the economies of scale associated with a larger
   fund. A larger fund should have an enhanced ability to effect portfolio
   transactions on more favorable terms and should have greater investment
   flexibility. Expenses such as audit expenses and accounting expenses that are
   charged on a per fund basis will be reduced.

- -  COSTS. The Board considered the fact that the investment manager has agreed
   to bear all solicitation expenses in order to achieve shareholder approval of
   the Reorganization and to bear any other costs of effecting the
   Reorganization.

- -  DILUTION. The Board considered the fact that the Reorganization will not
   dilute the interests of the current shareholders.

- -  PERFORMANCE. The Board considered the relative performance records of the
   Funds.

- -  POTENTIAL BENEFITS TO THE INVESTMENT MANAGER AND ITS AFFILIATES. The Board
   also considered the potential benefits from the Reorganization that could be
   realized by the investment manager and its affiliates. The Board recognized
   that the potential benefits to the investment manager consist principally of
   the elimination of expenses incurred in duplicative efforts to administer
   separate funds. The Board also noted, however, that shareholders of the
   Selling Fund will 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
a meeting held on Sept. 7-8, 2005, the Selling Fund Board members,

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       22
<Page>

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 the Buying Fund approved the Agreement at a meeting
held on Sept. 7-8, 2005. 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 the 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.

RECOMMENDATION AND VOTE REQUIRED

The Board recommends that shareholders approve the proposed Agreement. The
Agreement must be approved by a majority of the voting power of all shares
entitled to vote. If the Agreement is not approved, the Board will consider what
further action should be taken.

If shareholders approve the merger, it will take place shortly after the
shareholder meeting. In the interim, however, it will be important for the Fund
to have a properly elected Board and an IMSAgreement that has been approved by
shareholders.

PROPOSAL 2. ELECT BOARD MEMBERS

NOMINEES FOR THE BOARD. Nominees are listed in the following table. Each person
is a nominee for each of the 90 RiverSource Funds. Each nominee was elected a
member of the Board at the last regular shareholders' meeting except for Ms.
Flynn, Ms. Paglia, Mr. Laikind, Ms. Blatz and Ms. Pryor. These nominees were
recommended for the position of Board member by the independent Board members.
Ms. Flynn and Ms. Paglia began serving the fund in 2004. Mr. Laikind and Ms.
Blatz began serving the fund in 2005.

Each Board member will serve until the next regular shareholders' meeting or
until he or she reaches the mandatory retirement age established by the Board.
Under the current Board policy, members may serve until the end of the meeting
following their 75th birthday, or the fifteenth anniversary of the first Board
meeting they attend as members of the Board, whichever occurs first.

All nominees have agreed to serve. If an unforeseen event prevents a nominee
from serving, your votes will be cast for the election of a substitute selected
by the Board. Information on each nominee follows. Election requires a vote by a
majority of the fund's shares voted at the meeting.

BOARD COMMITTEES. The Board has several committees that facilitate
the work of the Board. The Executive Committee has authority to act for the full
Board between meetings. The Contracts Committee receives and analyzes reports
covering the level and quality of services provided under contracts with the
fund and advises the Board regarding actions taken on these contracts during the
annual review process. The Investment Review Committee considers investment
management policies and strategies; investment performance; risk management
techniques; and securities trading practices and reports areas of concern to the
Board.

The Board Effectiveness Committee's charter, Exhibit E, requires it to make
recommendations regarding nominees based on criteria approved by the Board. All
members of the Committee are independent. Nominee recommendations are based on a
matrix of skill sets, experience, and geographical location and each nominee
must have a background that demonstrates the ability to furthering the interest
of all shareholders. The Committee will consider recommendations from
shareholders who write to the Boards and provide detailed information about a
candidate. All candidates are processed in the same fashion; first by evaluating
a candidate's detailed information against the criteria; then interviewing those
candidates who best fill vacancies identified by the matrix.

You may write the Board by addressing a letter to Arne H. Carlson, the
independent Chairman of the Board or any other independent member of the Board,
at Board Services Corporation, 901 Marquette Avenue South, Suite 2810,
Minneapolis, MN 55402-3268. However, do not address letters to this address if
you are requesting some action regarding your investments. In order to avoid any
delay in processing a request regarding an investment, please address these
requests to 70100 Ameriprise Financial Center, Minneapolis, MN 55474.

The Joint Audit Committee, made up entirely of independent Board members,
operates under a written charter, Exhibit F. The Joint Audit Committee meets
with the independent auditors, internal auditors and corporate officers to
review and discuss audited financial statements, reports, issues, and compliance
matters. This Committee reports significant issues to the Board and makes
recommendations to the independent Board members regarding the selection of the
independent public accountant. More information regarding this Committee and the
fund's independent auditor is found in Section C.

During the 12-month period ended Sept. 30, 2005, the Board met 8 times,
Executive 2 times, Contracts 7 times, Investment Review 5 times, Board
Effectiveness 6 times and Joint Audit 4 times. All Board members had 100%
attendance except for Mr. Simpson who had 82% attendance due to serious illness
in January 2005.

BOARD MEMBER COMPENSATION. The following table shows the total compensation
received by each Board member from all of the RiverSource Funds. The funds do
not pay retirement benefits to Board members. Under a Deferred Compensation
Plan, independent Board members may defer receipt of their compensation.
Deferred amounts are treated as though equivalent dollar amounts had been

    Corporation, a company providing administrative services to the funds, are
    not paid by the funds. Mr. Carlson's total compensation was $373,750. Board
    member compensation is a combination of a base fee and meeting fees. Because
    the spin-off of Ameriprise Financial from American Express Company
    necessitated 5 additional meetings, Ameriprise Financial reimbursed the
    funds $23,500 for each member to cover those additional meetings. Mr.
    Laikind, Ms. Blatz and Ms. Pryor were not board members prior to Sept. 30,
    2005 and therefore are not included in the table.

PROPOSAL 3: APPROVE OR REJECT AN AMENDMENT TO THE ARTICLES OF INCORPORATION

The Fund is a Minnesota corporation and operates under an organizational
document called the articles of incorporation. The articles of incorporation set
forth various provisions relating to the authority of the fund to conduct
business and the governance of the fund.

The Board has approved, and recommends that shareholders approve, a proposal to
amend the fund's articles of incorporation (the "Articles"). The fund's
investments and investment policies will not change by virtue of the adoption of
the amendment to the Articles.

A. MINIMUM ACCOUNT VALUE

Generally, shareholders must invest at least $2,000 to open a fund account.
Section 7 of the Articles currently provides that the fund may redeem shares if
an account falls below a value of $1,000. Small accounts can be costly to
maintain and this provision allows the Board to close accounts that no longer
meet the fund's minimum standards. However, the current provision does not allow
the Board to redeem accounts if the value is higher than $1,000. In the future,
there may be circumstances in which a minimum account value higher than $1,000
is in the best interest of the fund and its shareholders. As a consequence, the
Board recommends that the Articles be amended to eliminate the reference to a
specific dollar amount. As proposed, the amended Articles will permit the Board
to establish a minimum account value that will be disclosed in the fund
prospectus. The Board will be able to change the minimum account value without
further action by shareholders.

If the change is approved, the Articles will be amended as follows
([Underline]additions are underlined[/Underline], [Strikethrough]deletions
are lined through[/Strikethrough]):

Article III, Section 7 will be amended to read:

Section 7. The Fund may redeem the shares of a shareholder if the amount
invested is less than [Strikethrough]$1,000[/Strikethrough] [Underline]an
amount determined by the Board of Directors and set forth in the current Fund
prospectus.[/Underline]

B. NAME CHANGE.

Historically the name of the fund has reflected the name of the investment
manager. Since 1999, the name of the fund has included the letters AXP, which is
an abbreviated form of the name American Express. In August 2005, American
Express Financial Corporation ("AEFC"), the fund's investment manager changed
its name to Ameriprise Financial, Inc. ("Ameriprise Financial") in anticipation
of its spin off from American Express Company, its parent company. On Oct. 1,
2005, Ameriprise Financial transferred responsibility for the fund's investment
advisory services to its wholly owned subsidiary, RiverSource Investments. The
Board made a corresponding change to the name of the fund by substituting the
name RiverSource for AXP. The name of the corporate entity can be changed only
with approval of the shareholders of all the underlying funds that make up the
corporation. The Board recommends that the name of the corporate entity also be
changed to include the name RiverSource instead of AXP. The changes are shown in
the table below.

This is the first shareholder meeting since the spin off of the investment
manager and the first opportunity for shareholders to consider a name change for
the corporation.

</Table>

BOARD RECOMMENDATION AND VOTE REQUIRED. The Board recommends that you vote to
approve the amendments to the Articles. The changes require the approval by a
majority of the shares voted at the meeting. The changes will be effective when
the amendments are filed with the Secretary of State's office. This filing is
expected to occur shortly after the shareholder meeting.

PROPOSAL 4: APPROVE OR REJECT AN INVESTMENT MANAGEMENT SERVICES AGREEMENT WITH
RIVERSOURCE INVESTMENTS, LLC

The fund pays fees to RiverSource Investments under an Investment Management
Services Agreement (the "IMS Agreement") for investment management services. The
services include providing the personnel, equipment and office facilities
necessary for the management of the fund's assets. Subject to the direction of
the Board and consistent with the fund's investment policies, the investment
manager decides what securities to buy, hold or sell. The investment manager
also executes buy and sell orders and provides research and statistical data to
support investment management activities. The Fund is part of a master/feeder
structure. In this structure, the fund invests all of its assets in a master
fund (the "portfolio") with the same policies as the fund. For purposes of this
discussion, the portfolio is referred to as a "fund".

SUMMARY OF CHANGES

INVESTMENT MANAGER. On Sept. 30, 2005, Ameriprise Financial became a publicly
traded company and on Oct. 1, 2005 transferred the investment management
functions to RiverSource Investments, a wholly owned subsidiary. While this
change did not cause a termination of the IMS Agreement, the Board determined
that it would be prudent to give shareholders an opportunity to vote on the
arrangement.

TERMS OF THE CURRENT IMS AGREEMENT. The fee the fund pays to RiverSource
Investments for its services under the current IMS Agreement is based on the net
assets of the fund and decreases as the size of the fund increases. The complete
fee schedule for the fund and other funds managed by RiverSource Investments is
found in Section C. The fund also pays its taxes, brokerage commission and
nonadvisory expenses, which include custodian fees; audit and certain legal
fees; fidelity bond premiums; registration fees for shares; consultant fees;
Board compensation; corporate filing fees; organizational expenses; expenses
incurred in connection with lending portfolio securities; and other expenses
properly payable by the fund, approved by the Board. Section C includes
information on the date of the current IMS Agreement, the date it was last
approved by shareholders and the reason why it was submitted to shareholders at
that time.

BASIS FOR RECOMMENDATION OF THE BOARD

Following announcement of the spin-off of Ameriprise Financial from American
Express Company, the Board and Ameriprise Financial agreed to review and revise,
where appropriate, the terms of all contracts, including the IMS Agreement,
pursuant to which Ameriprise Financial or its affiliates provides services to
the funds. Each year, the Board determines whether to continue the IMS Agreement
for each fund and, in doing so, evaluates the quality and level of service
received under the IMS Agreement and the costs associated with those services.
Accordingly, in March and April of each year, Ameriprise (formerly American
Express Financial Corporation) prepares detailed reports for the Board, which
include data prepared by independent organizations, to assist the Board in
making this determination. The Board accords considerable weight to the
deliberations and conclusions of its committees in determining whether to
continue the IMS Agreement.

After thorough review of the reports and data provided at a meeting held in
person on April 14, 2005, the Board, including a majority of its independent
members, determined that the quality and level of advisory services provided
pursuant to the IMS Agreement for each fund were satisfactory and that fees were
fair and reasonable. However, in light of the announced plans of the spin-off,
the Board approved continuation of the IMS Agreement for only an interim period
ending on the earlier of (i) the effective date of the spin-off; or (ii) the
approval of a new investment management services agreement with Ameriprise
Financial by the shareholders of each fund, but in no event for a period longer
than one year. While it was expected that the spin-off would not result in an
"assignment" of an IMS Agreement under the Investment Company Act of 1940 and,
therefore, would not cause the termination of the IMS Agreement according to its
terms, Schulte Roth & Zabel LLP, was retained as independent counsel to the
Board, advised the Board that the legal question of whether the spin-off would
result in an assignment turns on a highly fact-sensitive analysis. Therefore,
the Board determined, as a matter of prudence, to proceed as if each IMS
Agreement would terminate as a result of the spin-off. Accordingly, the Board
determined to renew each IMS Agreement for the interim period only and to
consider a new IMS Agreement for each fund prior to the spin-off.

For the six months following the April 2005 meeting, the Board and its
committees have been evaluating whether to approve a proposed IMS Agreement for
each fund with post-spin Ameriprise Financial. Schulte Roth & Zabel LLP, has
assisted the Board in fulfilling its statutory and other responsibilities
associated with the spin-off and the resulting consideration of new contracts,
including the proposed IMS Agreements. As a key step in this process,
independent counsel sent, on behalf of the independent members of the Board,

                                       33

a detailed and expansive request for information to American Express Company and
Ameriprise Financial, seeking specified information thought to be relevant to
the Board's consideration of the proposed contracts with post-spin Ameriprise
Financial. The Board and its committees were provided with a wealth of written
and oral information intended to assist them in considering the proposed
contracts, including the proposed IMS Agreements. Furthermore, in connection
with the Board's considerations as to whether post-spin Ameriprise Financial, as
an independent entity, would be capable of continuing to provide a high quality
of services to the funds, the Board's independent members retained their own
financial adviser, Credit Suisse First Boston LLC ("CSFB"). At the Board's
requests, CSFB provided various written materials and oral presentations
analyzing the capital adequacy of Ameriprise Financial. The costs of independent
counsel and CSFB and of additional meetings of the Board were borne by
Ameriprise Financial as part of the commitment of American Express Company to
ensure a complete and thorough review of the proposed spin-off and its effect on
the services provided by Ameriprise Financial and its subsidiaries.

During the course of the six-month period following the April 2005 meeting, the
Board and its committees met at five in-person meetings to consider the
information provided by American Express Company, Ameriprise Financial,
independent counsel and CSFB. At an in-person meeting held on Sept. 8, 2005,
based on all of the information provided as well as the deliberations occurring
at that meeting and the previous meetings held since the announcement of the
spin-off, the Board, including all of its independent members, approved the new
contracts, including each proposed IMS Agreement.

On Oct. 1, 2005, pursuant to an agreement between the fund and Ameriprise
Financial, the IMS Agreement was transferred to Riversource Investments, LLC, a
wholly-owned subsidiary of Ameriprise Financial.

FOR THESE REASONS, THE BOARD, INCLUDING ALL OF ITS INDEPENDENT MEMBERS,
RECOMMENDS THAT YOU APPROVE THE PROPOSED IMS AGREEMENT FOR YOUR FUND(S).

THE BOARD'S SPECIFIC CONSIDERATIONS RELATING TO THE PROPOSED IMS AGREEMENTS. In
carrying out its legal responsibilities associated with the consideration of the
proposed IMS Agreements, the Board evaluated the following four factors: (i) the
nature, extent and quality of services to be provided by RiverSource
Investments; (ii) the investment performance of the fund; (iii) the costs of the
services to be provided and the profits to be realized by Ameriprise Financial;
and (iv) the extent to which economies of scale would be realized as the fund
grows and whether the fee level reflects these economies of scale for the
benefit of fund investors.

NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE
FINANCIAL (AND ITS SUBSIDIARIES). The Board recognized that only a few months
had passed since its April 2005 determination to renew the IMS Agreement for
each fund and that in April 2005, it had concluded that the nature, extent and
quality of services provided by Ameriprise Financial were satisfactory and
consistent with those that would be expected for a fund family of the size of
the funds. However, the Board also recognized that this assessment must be
supplemented with an evaluation of whether the spin-off or other factors would
result in any changes to the advisory services currently provided to the funds.
In this regard, the Board focused its evaluation on the following factors
potentially impacting the nature, extent and quality of advisory services to be
provided by RiverSource Investments: (i) Ameriprise Financial's projected
capital structure and capital adequacy as a stand-alone entity; (ii) its legal
and regulatory risks; (iii) its ability to retain and attract personnel; and
(iv) its ability to successfully rebrand its products and services. Based on
extensive presentations and reports by Ameriprise Financial, CSFB and
independent counsel, the Board concluded that the proposed capital structure
(which includes certain indemnification commitments made by American Express)
should enable RiverSource Investments to continue to provide a high quality and
level of advisory services to the funds. In making this determination, the Board
took into account representations by management of Ameriprise Financial that
projected capital levels would allow Ameriprise Financial to continue to meet
its legal and compliance responsibilities, build its distribution network,
pursue technological upgrades, make capital commitments necessary to retain and
attract key personnel devoted to legal and compliance responsibilities,
portfolio management and distribution, and pursue smaller asset management
acquisitions to help grow its business. The Board accorded significant weight to
CSFB's confirmation as to the reasonableness of the foregoing representations.
The Board also considered the fact that there were no expected departures of key
personnel involved in the portfolio management, operations and marketing of the
funds as a result of the announcement of the spin-off.

The Board concluded that, based on all of the materials and information provided
(and with the assistance of independent counsel), post-spin Ameriprise Financial
would be in a position to continue to provide a high quality and level of
investment management services to the funds.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       35

INVESTMENT PERFORMANCE. The Board next focused on investment performance. The
Board reviewed reports documenting the fund's performance over one-, three-
and/or five-year periods, as well as the entire period during which its current
portfolio manager has managed the fund, and compared to relevant Lipper and
market indices. The Board took into account its determination in April 2005 that
investment performance either met expectations or, if not, that appropriate
action (such as changes to portfolio management) had been (or was being) pursued
in order to help the fund achieve its longer-term performance objective.

The Board also considered that it has received monthly performance reports for
the funds. The Board and its committees concluded in September 2005 that there
have been no significant deviations from April's overall performance data.

COST OF SERVICES PROVIDED. The Board evaluated comparative fees and the costs of
services to be provided under the current and proposed IMS Agreements, including
fees charged by RiverSource Investments to its institutional clients and paid to
sub-advisers. The Board studied RiverSource Investments' effort (i.e., its
"pricing philosophy") to set substantially all funds' total expense ratios at or
below the median expense ratio of a group of comparable mutual funds compiled by
Lipper, Inc. The Board observed that the proposed advisory fee changes are
designed to work in tandem with proposed changes to the administrative services
fees. It also noted that RiverSource Investments agreed to voluntarily imposed
expense caps or waivers to achieve this pricing objective whenever the expense
ratio exceeded the median expense ratio by more than three basis points unless
the higher ratio was due to the impact of the performance fee adjustment or was
due to the added costs associated with having subadvisers manage a fund. The
Board considered that, with respect to all funds, other than [Mid Cap Growth,
Small Cap Advantage, Strategic Allocation, Variable Portfolio Diversified Equity
Income and Variable Portfolio Mid Cap Growth], advisory fees under the proposed
IMS Agreements would stay the same or decrease (as indicated in Table B-5,
below) and that, with respect to [Diversified Equity Income, Mid Cap Growth,
Small Cap Advantage, VP Diversified Equity Income and VP Mid Cap Growth], would
increase under each applicable proposed IMS Agreement. The Board accorded
significant weight to the fact that the proposed changes in fee schedules were
intended primarily to achieve a rational pricing model applied consistently
across the various product lines in the fund family, while assuring that overall
fees for each fund are in line with the "pricing philosophy." With respect to
the equity and balanced funds, the Board also took into account the effect of
the proposed performance incentive adjustment on the advisory fee. In this
regard, the Board took into account its past determinations regarding the
appropriateness of (i) the use of the relevant index for each fund for the

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       36
<Page>

comparison of performance; (ii) the methodology for determining when the Board
may change an index used to calculate the performance incentive adjustment;
(iii) the periods used for averaging the funds' assets and computing investment
performance; and (iv) the length of the period over which performance is
computed. Furthermore, the Board considered that with respect to the relevant
sub-advised funds, there was limited opportunity for these funds to achieve
large scale growth and thus provide RiverSource Investments with potential
economies of scale.

The Board next considered the expected profitability to RiverSource Investments
and its affiliates derived from its relationship with the fund, recalling the
April 2005 determination that the profitability level was appropriate. The Board
noted that projected profitability of RiverSource Investments would allow it to
operate effectively and, at the same time, reinvest in its businesses. The Board
also considered that the proposed changes in advisory fees and the mergers of
certain funds would result in revenue gains, while taking into account that
these increases would not materially alter profit margins due to expected
increases in costs associated with the spin-off, particularly rebranding and
separation. CSFB also reported that Ameriprise Financial's projected level of
return on equity was generally reasonable in light of the returns on equity of
its industry competitors. In evaluating profitability, the Board also considered
the benefits Ameriprise Financial obtains through the use of commission dollars
paid on portfolio transactions for the funds and from other business
relationships that result from managing the funds. The Board also considered the
fees charged by Ameriprise Financial to its institutional clients and paid to
sub-advisers, noting the differences in services provided in each case. In light
of these considerations, the Board concluded that projected profitability levels
were appropriate.

ECONOMIES OF SCALE. The Board also considered the "breakpoints" in fees that
would be triggered as fund net asset levels grew and the extent to which
shareholders would benefit from such growth. The Board observed that the revised
fee schedules under the proposed IMS Agreement would continue to provide
breakpoints similar to those in place pursuant to the current IMS Agreement.
Accordingly, the Board concluded that the proposed IMS Agreement provides
adequate opportunity for shareholders to realize benefits as fund assets grew.

OTHER CONSIDERATIONS. In addition, the Board accorded weight to the fact that,
under the proposed IMS Agreement, RiverSource Investments is held to a higher
standard of care than under the current IMS Agreements. The Board also noted
Ameriprise Financial's commitment to a culture that adheres to ethical business
practice, assigns accountability to senior management and seeks to identify
conflicts and propose appropriate action to minimize the risks posed by

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       37
<Page>

the conflicts. Furthermore, the Board recognized that it was not limited to
considering management's proposed contracts. In this regard, the Board evaluated
the circumstances under which it would consider the retention of an investment
adviser different from RiverSource Investments (or its subsidiaries). The Board
concluded, based on its consultation with independent counsel, that pursuing the
retention of a different adviser was not necessary,primarily because, in its
best judgment, RiverSource Investments continues to be basically the same
organization (from a functional and managerial standpoint) as it was prior to
the spin-off. The Board reasoned that shareholders purchased shares of the funds
with an expectation that the current investment advisory organization would be
servicing the funds.

As a result of all of the foregoing, the Board determined that the fees to be
paid under each proposed IMS Agreement were fair and reasonable in light of
services proposed to be provided.

BOARD RECOMMENDATION AND VOTE REQUIRED. For the foregoing reasons, the Board
recommends that shareholders of each fund approve the applicable proposed IMS
Agreement. The proposed IMS Agreement must be approved by the lesser of (a) a
majority of the fund's outstanding shares or (b) 67% of the shares voted at the
meeting, so long as more than 50% of the shares actually vote. If shareholders
approve the proposed IMS Agreement, it will take effect shortly after the
shareholder meeting. If the proposed IMS Agreement is not approved, the Board
will consider appropriate steps to take.

SECTION B -- PROXY VOTING AND SHAREHOLDER MEETING INFORMATION

VOTING. You are entitled to vote based on your total dollar interest in the
Fund. Each dollar is entitled to one vote. For those of you who cannot come to
the meeting, the Board is asking permission to vote for you. The shares will be
voted as you instruct either by mail, telephone or internet. Signed proxy cards
returned without instructions will be voted in favor of all proposals.

The corporation of which the Fund is part issues several series of common stock.
Each series is a separate fund. On the election of directors and the amendment
of the Articles of Incorporation, you vote together with the owners of shares of
all the other funds that are part of the corporation. On the Reorganization and
the IMS Agreement you vote together with the owners of the other shares in your
fund.

In voting for Board members, you may vote all of your shares cumulatively. This
means that you have the right to give each nominee an equal number of votes or
divide the votes among the nominees as you wish. You have as many votes as the
number of dollars you own on the record date, multiplied by the

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       38
<Page>

number of Board members to be elected. If you elect to withhold authority for
any individual nominee or nominees, you may do so by marking the box labeled
"For All Except," and by striking the name of any excepted nominee, as is
further explained on the card itself. If you do withhold authority, the proxies
will not vote shares equivalent to the proportionate number applicable to the
names for which authority is withheld.

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.

MASTER/FEEDER FUNDS. Selective currently is part of a master/feeder structure.
The feeder fund seeks its investment objective by investing its assets in a
master fund with the same policies. The master fund invests in and manages the
securities. Immediately prior to the Reorganization, the Board intends to
withdraw the Fund's assets from the master fund.

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 corporation or by shareholders of a fund or by a class of
shares of the fund where appropriate. 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.

<Page>

SHAREHOLDER PROPOSALS. No proposals were received from shareholders. The 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 the 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 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 C.

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 in favor of the proposals 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 proposals. They will vote against any adjournment
those shares that have voted against the proposals. 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.

(1) Shareholders approved (1) basing the fee solely on the assets of the fund,
    not on the assets of all of the funds in the fund family and (2) eliminating
    provisions regarding administration and accounting services. The fund and
    the investment manager then entered into a separate Administrative Services
    Agreement.

THE FUND'S INDEPENDENT REGISTERED PUBLIC ACCOUNTANT. The 1940 Act provides that
every registered investment company must be audited at least once each year by
independent registered public accountants selected by a majority of the
independent Board members. The Selling Fund's Board has selected KPMG LLP to be
the Fund's independent registered public accountant for the current fiscal year.
KPMG LLP, in accordance with Independence Standards Board Standard No. 1 (ISB
No. 1), has confirmed in writing to the Board's Joint Audit Committee that they
are independent accountants with respect to the Fund.

The independent accountants examine the financial statements for the Fund that
are set forth in the annual report to shareholders and provide other requested
non-audit and tax-related services to the Fund. The Joint Audit Committee
reviewed and discussed the audited financial statements with RiverSource
Investments and reviewed with KPMG LLP the matters required to be discussed by
SAS 61 (for example, methods used to account for significant unusual
transactions).

The Joint Audit Committee does not consider other non-audit services provided by
KPMG LLP to be incompatible with maintaining the independence of KPMG LLP in its
audits of the Fund, taking into account representations from KPMG LLP, in
accordance with ISB No. 1, regarding its independence from the Fund and its
related entities.

Representatives of KPMG LLP are expected to be present at the meeting. They will
be given the opportunity to make a statement to shareholders and are expected to
be available to respond to any questions that may be raised at the meeting.

JOINT AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES. Pursuant to the
pre-approval requirements of the Sarbanes-Oxley Act of 2002, all services to be
performed by KPMG LLP for the Fund; the Fund's investment adviser; and any
entity controlling, controlled by, or under common control with the investment
adviser that provides ongoing services to the Fund, must be pre-approved by the
Joint Audit Committee.

EXHIBIT A

FORM OF AGREEMENT AND PLAN OF REORGANIZATION

This Agreement and Plan of Reorganization dated as of ___, 2005 (the
"Agreement") is between AXP Income Series, Inc. (the "Selling Corporation"), a
Minnesota corporation, on behalf of its series, RiverSource Selective Fund (the
"Selling Fund"), and AXP Fixed Income Series, Inc. (the "Buying Corporation), a
Minnesota corporation, on behalf of its series, RiverSource Diversified Bond
Fund (the "Buying Fund), and RiverSource Investments, LLC (solely for the
purposes of Section 3c and 10 of the Agreement).

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

1.   SHAREHOLDER APPROVAL. The Selling Fund will call a meeting of its
     shareholders for the purpose of approving the Agreement and the
     transactions it contemplates (the "Reorganization"). The Buying Fund agrees
     to furnish data and information, as reasonably requested, for the proxy
     statement to be furnished to shareholders of the 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, the Selling Corporation
          will convey all of the assets of the Selling Fund to the Buying Fund.
          The Buying Fund will assume all liabilities of the Selling Fund. At
          the Closing, the Buying Corporation will deliver shares of the Buying
          Fund, including fractional shares, to the Selling Corporation. The
          number of shares will be determined by dividing the value of the net
          assets of shares of the Selling Fund, computed as described in
          paragraph 3(a), by the net asset value of one share of the Buying
          Fund, computed as described in paragraph 3(b). The Selling Fund will
          not pay a sales charge on the receipt of Buying Fund shares in
          exchange for the assets of the Selling Fund. In addition, the
          shareholders of the Selling Fund will not pay a sales charge on
          distribution to them of shares of the 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 the Selling Fund and receipt of all necessary
          regulatory approvals, or such later date as the parties may agree.

                                       A.1
<Page>

3.   VALUATION OF NET ASSETS.

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

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

     c.   At the Closing, the Selling Fund will provide the Buying Fund with a
          copy of the computation showing the valuation of the net asset value
          per share of shares of the Selling Fund on the Valuation Date. The
          Buying Fund will provide the Selling Fund with a copy of the
          computation showing the determination of the net asset value per share
          of shares of the 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, the Selling
          Corporation will liquidate the Selling Fund and distribute shares of
          the Buying Fund to the Selling Fund's shareholders of record. The
          Buying Fund will establish shareholder accounts in the names of each
          Selling Fund shareholder, representing the respective pro rata number
          of full and fractional shares of the Buying Fund due to each
          shareholder. All issued and outstanding shares of the Selling Fund
          will simultaneously be cancelled on the books of the Selling
          Corporation. The Buying Fund or its transfer agent will establish
          shareholder accounts in accordance with instructions from the Selling
          Corporation.

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

     c.   Promptly after the distribution, the Buying Fund or its transfer agent
          will notify each shareholder of the 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 the Selling Fund,
          and in no event later than twelve months from the date of the Closing,
          the Selling Fund will be dissolved.

          of the last fiscal year, and the subsequent unaudited semi-annual

          execution of this Agreement and the completion of the transactions
          contemplated by it will not conflict with, or constitute a breach of,
          any material contract or other instrument to which the Buying Fund is
          subject. The transactions will not result in any violation of the
          provisions of the Articles or any law, administrative regulation or

     i.   Litigation. There is no litigation, administrative proceeding or
          investigation before any court or governmental body currently pending
          or, to the knowledge of the Buying Fund, threatened, that would

          condition or the conduct of its business, or that would prevent or
          hinder completion of the transactions contemplated by this Agreement.

          the Internal Revenue Service or by any state or local tax authority
          for taxes in excess of those already paid.

          completion of the 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 the Articles or any law, administrative
          regulation or administrative or court decree applicable to the Selling
          Fund.

     g.   Liabilities. There are no liabilities of the Selling Fund other than:

          -    liabilities disclosed in the Selling Fund Financial Statements,

          -    liabilities incurred in the ordinary course of business
               subsequent to the date of the latest annual or semi-annual
               financial statements, or

          -    liabilities previously disclosed to the Buying Fund, none of
               which has been materially adverse to the business, assets or
               results of operation of the Selling Fund.

     h.   Litigation. There is no litigation, administrative proceeding or
          investigation before any court or governmental body currently pending
          or, to the knowledge of the Selling Fund, threatened, that would
          materially and adversely affect the Selling Fund, its financial
          condition or the conduct of its business, or that would prevent or
          hinder completion of the transactions contemplated by this Agreement.
          The Selling Fund knows of no facts that might form the basis for the
          institution of any such litigation, proceeding or investigation and is
          not a party to or subject to the provisions of any order, decree or
          judgment.

     i.   Contracts. Except for contracts and agreements previously disclosed to
          the Buying Corporation, the Selling Fund is not a party to or subject
          to any material contract, debt instrument, plan, lease, franchise,
          license or permit.

     j.   Taxes. The Selling Fund has qualified as a regulated investment
          company under the Internal Revenue Code with respect to each taxable
          year since commencement of its operations and will qualify as
          regulated investment company at all times through the Closing. As of
          the Closing, the Selling Fund will (i) have filed all federal and
          other tax returns and reports that have been required to be filed,
          (ii) have paid or provided for payment of all federal and other taxes
          shown to be due on such returns or on any assessments received, (iii)
          have adequately provided for all tax liabilities on its books, (iv)
          except as disclosed to the Buying Fund, not have had any tax
          deficiency or liability asserted against it or question with respect
          thereto raised, and (v) except as disclosed to the Buying Fund, not be
          under audit by the Internal Revenue Service or by any state or local
          tax authority for taxes in excess of those already paid.

EXHIBIT B

MATTERS SUBJECT TO APPROVAL AT REGULAR MEETING OF BUYING FUND

In addition to voting on proposals to elect Board members, to amend the Articles
of Incorporation and to approve the IMS Agreement, Buying Fund shareholders will
consider the following:

APPROVE OR REJECT CHANGES IN FUNDAMENTAL INVESTMENT POLICIES

The fund has some investment policies that are fundamental. This means the
policies can be changed only with the approval of shareholders. RiverSource
Investments recommended to the Board that certain of those policies be modified
in order to standardize the policies for all funds and to eliminate unnecessary
limitations.

RiverSource Investments believes that increased standardization will help to
promote operational efficiencies and facilitate monitoring of compliance with
fundamental investment policies. Adoption of a new or revised policy is not
intended to change current investment techniques employed for the fund. The
Board recommends the following changes to the fund's fundamental investment
policies:

A. DIVERSIFICATION.

The Board recommends that the fund's fundamental policy with respect to
diversification be revised to give the fund the maximum flexibility permitted by
the 1940 Act. The Board recommends that shareholders vote to replace the fund's
current fundamental investment policy with the following policy (additional or
revised language is [Underline]underlined[/Underline]):

    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 [Underline]or
    other investment companies[/Underline], and except that up to 25% of the
    fund's total assets may be invested without regard to this 5% limitation.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       B.1
<Page>

The percentage limits in the proposed policy are required under the 1940 Act.
The amended policy makes one change from the current policy: subject to
applicable 1940 Act requirements, it would permit the fund to invest without
limit in the securities of other investment companies. Pursuant to an exemptive
order granted by the Securities and Exchange Commission (the "SEC"), the fund
may invest up to 25% of its total assets in a non-publicly offered money market
fund managed by RiverSource Investments (the "cash pool fund"). The cash pool
fund is not expected to pay investment advisory, management, or transfer agent
fees, although it may do so subject to the conditions of the SEC order and Board
approval. The cash pool fund will incur minimal costs for services, such as
custodian and auditor fees. The investment manager anticipates that making use
of the cash pool fund will benefit the fund by enhancing the efficiency of cash
management and by providing increased short-term investment opportunities. If
the proposal is approved, the cash pool fund is expected to serve as a principal
option for managing the cash positions of the fund. Future amendments to the
fund's fundamental diversification policy would continue to require shareholder
approval.

B. TEN PERCENT LIMITATION IN SINGLE ISSUER.

The Board recommends that the fund's fundamental policy with respect to
investment in a single issuer be revised to permit the fund the maximum
flexibility permitted by the 1940 Act. The Board recommends that shareholders
vote to replace the fund's current fundamental investment policy with the
following policy (additional language is underlined):

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

The 10% percent limit in the proposed policy is required under the 1940 Act.
Under the 1940 Act, a fund is permitted to invest up to 25% of its assets
without regard to the 10% limitation. The Board recommends that shareholders
amend the policy so that it reflects the terms of the 1940 Act. The proposal is
not expected to materially affect the operation of the fund. However, the
adoption of the proposed investment policy will standardize investment policies.

                                       B.2
<Page>

C. LENDING

The Board recommends that the fund's fundamental policies with respect to
lending be replaced with the following policy:

    The Fund will not 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, loan participation or other debt
    securities, or from entering into repurchases agreements.

Currently each of the funds has two policies with respect to lending. One policy
limits lending of portfolio securities to 30% of net assets and the other policy
limits cash loans to 5% of total assets. In addition, certain funds have a
policy prohibiting loans to the investment manager, or to board members and
officers of the investment manager or the fund. This third policy simply states
a prohibition of the 1940 Act and the fund is not required to declare this
policy as a fundamental policy. It is proposed that all three of these policies
be superseded by the policy stated above.

The proposal is not expected to materially affect the operation of the fund.
However, the proposed policy would clarify that the fund can participate in an
interfund borrowing and lending program with other RiverSource Funds, subject to
the requirements of an SEC exemptive order. A fund may only borow money for
temporary purposes and not make investments. Appropriate safeguards will be
implemented to assure that the fund will not be disadvantaged by making loans to
affiliated funds. The proposed policy also would confirm the fund's ability to
invest in direct debt instruments such as loans and loan participations, which
are interests in amounts owed to another party by a company, government or other
borrower. These types of securities may have additional risks beyond
conventional debt securities because they may provide less legal protection for
the fund, or there may be a requirement that the fund supply additional cash to
a borrower on demand. Finally, the adoption of the proposed investment policy
will advance the goal of standardizing investment policies.

D. BORROWING

The Board recommends that the fund's fundamental policy with respect to
borrowing be replaced with the following policy:

    The fund may not 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.

Funds typically borrow money to meet redemptions in order to avoid forced,
unplanned sales of portfolio securities. This technique allows RiverSource
Investments greater flexibility in managing the fund's cash flow. The current
policy limits borrowing to "emergency or extraordinary purposes". In order to
avoid debate over what constitutes emergency or extraordinary purposes, it is
proposed to revise the policy to reflect that the purposes, whatever the
circumstances, must be temporary. The fund may not use borrowing for leverage or
for investment purposes. In addition, the policy for certain funds includes a
prohibition on borrowing "property". The Board recommends the term be deleted in
order to standardize investment policies.

BOARD RECOMMENDATION AND VOTE REQUIRED. The Board recommends that shareholders
approve the proposed changes. Changes in fundamental policies must be approved
by the lesser of (a) a majority of the fund's outstanding shares or (b) 67% of
the shares voted at the meeting, so long as more than 50% of the shares actually
vote. If the any of the proposed changes is not approved, the fund will continue
to operate under its current policy.

EXHIBIT C

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)  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;

(b)  A sale, lease, transfer, or other disposition of all or substantially all
     of the property and assets of the corporation, but not including a
     transaction permitted without shareholder approval in section 302A.661,
     subdivision 1, or 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;

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       C.1
<Page>

(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;
     or

(e)  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)  The 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 or (2) the corporation whose shares will be acquired by the
     acquiring corporation 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.

(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.

SUBDIVISION 4. OTHER RIGHTS. The shareholders of a corporation who have a right
under this section to obtain payment for their shares do not have a right at law
or in equity to have a corporate action described in subdivision 1 set aside or
rescinded, except when the corporate action is fraudulent with regard to the
complaining shareholder or the corporation.

302A.473. PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS

SUBDIVISION 1. DEFINITIONS.

(a)  For purposes of this section, the terms defined in this subdivision have
     the meanings given them.

     successor by merger of that issuer.

(c)  "Fair value of the shares" means the value of the shares of a corporation
     immediately before the effective date of the corporate action referred to
     in section 302A.471, subdivision 1.

     the corporate action referred to in section 302A.471, subdivision 1, up to
     and including the date of payment, calculated at the rate provided in
     section 549.09 for interest on verdicts and judgments.

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, 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 all shareholders who have
     complied with subdivision 3 and to all shareholders entitled to dissent if
     no shareholder vote was required, a notice that contains:

     (1)  The address to which a demand for payment and certificates of
          certificated shares must be sent in order to obtain payment and the
          date by which they must be received;

     (2)  Any restrictions on transfer of uncertificated shares that will apply
          after the demand for payment is received;

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       C.3
<Page>

     (3)  A form to be used to certify the date on which the shareholder, or the
          beneficial owner on whose behalf the shareholder dissents, acquired
          the shares or an interest in them and to demand payment; and

     (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.

                                       C.4
<Page>

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, 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.

CORPORATE REORGANIZATION

On Sept. 30, 2005, Ameriprise Financial, Inc. (Ameriprise Financial) (formerly
American Express Financial Corporation) was spun off to shareholders of its
parent corporation, American Express Company (American Express), and is now a
separate public company, trading under the ticker symbol AMP. Ameriprise
Financial provides administrative services to the Fund and is the parent company
of the Fund's investment manager, RiverSource Investments, LLC; the Fund's
distributor, Ameriprise Financial Services, Inc. (formerly American Express
Financial Advisors Inc.); and the Fund's transfer agent, RiverSource Service
Corporation (formerly American Express Client Service Corporation). On Oct. 1,
2005, the Fund changed its name, such that it no longer is branded AXP(R). The
Fund now bears the RiverSource(SM) brand. Ameriprise Financial and its
subsidiaries are no longer affiliated with American Express.

THE FUND

OBJECTIVE

RiverSource Diversified Bond Fund (the 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. Because any investment involves risk, achieving this
objective cannot be guaranteed.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the 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 to
achieve higher yield and/or capital appreciation by buying lower-quality (junk)
bonds. The Fund may invest up to 15% 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 the Fund's objective, the investment manager
(RiverSource Investments, LLC) 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.

- -  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, 2005, was 4.26 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%.

                                       D.3
<Page>

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.

PRINCIPAL RISKS

Please remember that with any mutual fund investment you may lose money.
Principal risks associated with an investment in the Fund include:

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. 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 company 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.

INTEREST RATE RISK. 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. 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.

PAST 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. See "Fee and Expenses" for any current fee
waivers/expense caps.

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 and Class Y shares of the Fund. These returns are compared to
the indexes shown for the same periods. Past performance for Class Y for the
periods prior to March 20, 1995 may be calculated based on the performance of
Class A, adjusted to reflect differences in sales charges, but not differences
in annual Fund operating expenses. 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 Y 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.

The 4.75% sales charge applicable to Class A shares of the Fund is not reflected
in the bar chart; if reflected, returns would be lower than those shown. The
performance of other classes may vary from that shown because of differences in
expenses.

EXAMPLES

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
indicated and then redeem all of your shares at the end of those periods. 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:

OTHER INVESTMENT STRATEGIES AND RISKS

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 Fund may use, see the Fund's Statement of
Additional Information (SAI) and its 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.

PORTFOLIO TURNOVER. Trading of securities may produce capital gains, which are
taxable to shareholders when distributed. Active trading may also increase the
amount of commissions or mark-ups paid to broker-dealers that the Fund pays when
it buys and sells securities. The Fund's historical portfolio turnover rate,
which measures how frequently the Fund buys and sells investments, is shown in
the "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 Fund's
securities transactions and the dollar value of brokerage commissions paid by
the Fund are set forth in the SAI. The brokerage commissions set forth in the
SAI do not include implied commissions or mark-ups (implied commissions) paid by
the Fund for principal transactions (transactions made directly with a dealer or
other counterparty), including most fixed income securities and

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.10
<Page>

certain derivatives. In addition, 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.

Additional information regarding securities transactions can be found in the
SAI.

TRANSFER AGENCY SERVICES. RiverSource Service Corporation, 70100 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, which varies by share 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 the Fund for
these services are included under "Other expenses" in the expense table under
"Fees and Expenses" RiverSource funds are primarily sold through Ameriprise
Financial Services which is allocated a portion of these fees for providing
services to Fund shareholders. RiverSource Service Corporation may also pay a
portion of these fees to other financial intermediaries that provide
sub-recordkeeping and other services to Fund shareholders.

The SAI provides additional information about the services provided and the fee
schedules for the agreements set forth above.

PAYMENTS TO FINANCIAL INTERMEDIARIES

RiverSource Investments and its affiliates may make additional cash payments out
of their own resources to financial intermediaries, such as broker-dealers,
banks, qualified plan administrators and recordkeepers, or other institutions,
including inter-company allocation of resources to affiliated broker-dealers
such as Ameriprise Financial Services (financial intermediaries) in connection
with the sale of shares of the Fund and/or the provision of services to the Fund
or its shareholders. These payments may create an incentive for the financial
intermediary, its employees or registered representatives to recommend or sell
shares of the Fund to its customers. 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 under distribution or shareholder
servicing plans, or paid by the Fund for shareholder account maintenance,
sub-accounting or recordkeeping services provided directly by the financial
intermediary providing such services. In exchange for these payments and
inter-company allocations, RiverSource Investments and its affiliates may
receive preferred access to registered representatives of a financial
intermediary (for example, the ability to make presentations in branch offices
or at conferences) or preferred access to customers of the financial
intermediary (for example, the ability to advertise or directly interact with
the financial intermediary'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 intermediary
or its representatives to recommend or sell shares of a fund and may create a
conflict of interest between a financial intermediary's financial interest and
its duties to its customers. Please contact the financial intermediary through
which you are purchasing shares of the Fund for details about any payments it
may receive in connection with the sale of Fund shares or the provision of
services to the Fund.

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 intermediary. These payments may also be negotiated based
on other criteria or factors including, but not limited to, the financial
intermediary'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 intermediary 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.

                                      D.15
<Page>

From time to time, RiverSource Investments and its affiliates may make other
payments, including non-cash compensation, to financial intermediaries or their
representatives 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 intermediaries and their representatives are subject.

ADDITIONAL MANAGEMENT INFORMATION

MANAGER OF MANAGER EXEMPTION. The Fund has received an order from the Securities
and Exchange Commission that permits the investment manager, subject to the
approval of the Board, to appoint a subadviser or change the terms of a
subadvisory agreement for the Fund without first obtaining shareholder approval.
Before the Fund 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. If shareholder approval is received, the Fund may add or change
unaffiliated subadvisers or the fees paid to subadvisers from time to time
without the expense and delays associated with obtaining shareholder approval of
the change. There is no assurance shareholder approval will be received, and no
changes will be made without shareholder approval until that time.

AFFILIATED FUNDS-OF-FUNDS. RiverSource Investments also serves as investment
manager to the RiverSource Portfolio Builder Funds (Portfolio Builder Funds), a
group of six funds-of-funds that provide asset-allocation services to
shareholders by investing in shares of other RiverSource funds, including the
Fund. The Fund may experience relatively large purchases or redemptions from the
Portfolio Builder Funds. Although RiverSource Investments seeks to minimize the
impact of these transactions by structuring them over a reasonable period of
time, the Fund may experience increased expenses as it buys and sells securities
to manage transactions for the Portfolio Builder Funds. In addition, because the
Portfolio Builder Funds may own a substantial portion of the Fund, a redemption
by the Portfolio Builder Funds could cause the 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 Fund's Board on
the steps it has taken to manage any potential conflicts.

FUND HOLDINGS DISCLOSURE. The Fund's 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 the Fund. A description
of these policies and procedures is included in the Fund's SAI.

BUYING AND SELLING SHARES

TRANSACTIONS THROUGH UNAFFILIATED FINANCIAL INTERMEDIARIES

Where authorized by the distributor, shares of the Fund may be available through
certain 401(k) or other qualified plans, banks, broker-dealers or other
institutions (financial intermediaries). These financial intermediaries may
charge you additional fees for the services they provide and they may have
different policies not described in this prospectus. Some policy differences may
include different minimum investment amounts, exchange privileges, fund choices
and cutoff times for investments. Additionally, recordkeeping, transaction
processing and payments of distributions relating to your account may be
performed by the financial intermediaries or their representatives through whom
shares are held. Since the Fund may not have a record of your transactions, you
should always contact the financial intermediary through whom you purchased the
Fund to make changes to or give instructions concerning your account or to
obtain information about your account. The Fund and the distributor are not
responsible for the failure of one of these financial intermediaries to carry
out its obligations to its customers.

AVAILABILITY AND TRANSFERABILITY OF FUND SHARES. Please consult your investment
professional or financial intermediary to determine availability of the Fund.
Currently, RiverSource funds may be purchased or sold through affiliated
broker-dealers of RiverSource Investments, including Ameriprise Financial
Services and Securities America, Inc. (Securities America), and through a
limited number of unaffiliated institutions. If you set up an account at another
financial intermediary, you will not be able to transfer RiverSource fund
holdings to that account unless that institution has obtained a selling
agreement with the distributor of the RiverSource funds. If you set up an
account with an unaffiliated financial intermediary that does not have, and is
unable to obtain, such a selling agreement, you must either maintain your
position with Ameriprise Financial Services or Securities America, find another
financial intermediary with such a selling agreement, or sell your shares,
paying any applicable deferred sales charge. Please be aware that transactions
in taxable accounts would generate a taxable event and may result in an
increased income tax liability.

For more information, please call RiverSource Service Corporation at
(888) 791-3380.

The public offering price for Class A shares of the Fund is the net asset value
(NAV) plus a sales charge, and for Class B, C, and Y shares, 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 distributor. This may include, for example, providing the fund
name and account number, the amount of the transaction and all required
signatures. For more information, refer to the sections on "Purchasing Shares"
and "Exchanging/Selling Shares," or contact your financial advisor or investment
professional. If you buy or sell shares through an authorized financial
intermediary, consult that firm to determine its procedures for accepting and
processing orders. The financial intermediary may charge a fee for its services.

VALUING FUND SHARES

The NAV is the value of a single share of the Fund. The NAV is determined by
dividing the value of the 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. The Fund's securities are valued primarily on the basis of
market quotations 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 are not readily available, securities are priced
at fair value based on procedures adopted by the Board. These procedures are
also used when the value of a security held by the Fund is materially affected
by events that occur after the close of the primary market on which the security
is traded but prior to the time as of which the Fund's NAV is determined.
Valuing securities at fair value involves reliance on judgment. The fair value
of a security is likely to differ from any available quoted or published price.
To the extent that the Fund has significant holdings of high yield securities
that may trade infrequently, fair valuation may be used more frequently than for
other funds.

Foreign investments are valued in U.S. dollars. Some of the 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.

INVESTMENT OPTIONS

1. CLASS A shares are sold to the public with a sales charge at the time of
   purchase and an annual distribution and shareholder servicing (12b-1) fee of
   0.25%.

2. CLASS B shares are sold to the public with a contingent deferred sales charge
   (CDSC) and an annual distribution and shareholder servicing (12b-1) fee of
   1.00%.

3. CLASS C shares are sold to the public without a sales charge at the time of
   purchase and with an annual distribution and shareholder servicing (12b-1)
   fee of 1.00%. Class C shares redeemed within one year after purchase may be
   subject to a CDSC.

4. CLASS Y shares are sold to qualifying institutional investors without a sales
   charge or distribution fee, but with a separate shareholder servicing fee of
   0.10%. Please see the SAI for information on eligibility requirements to
   purchase Class Y shares.

The distribution and shareholder servicing fees for Class A, Class B and Class C
shares 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 the Fund's shares and
providing services to Fund shareholders. These expenses include payment of
distribution and shareholder servicing fees to financial intermediaries that
sell shares of the Fund. Financial intermediaries receive shareholder servicing
fees equal to 0.25% of the average daily net assets of Class A, Class B and
Class C shares sold and held through them. For Class A and Class B 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 intermediaries also receive distribution fees equal 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, the
Fund's distributor retains the 0.75% distribution fee in order to finance the
payment of sales commissions to financial intermediaries that sell Class B
shares, and to pay for other distribution related expenses. Financial
intermediaries may compensate their financial advisors and investment
professionals with the shareholder servicing and distribution fees paid to them
by the distributor.

The shareholder servicing fees for Class Y shares are used to reimburse the
distributor for providing services and assistance to shareholders regarding
ownership of their shares or their accounts.

The Fund also offers an additional class of shares, Class I, exclusively to
certain institutional investors. Class I shares are made available through a
separate prospectus supplement provided to investors eligible to purchase the
shares.

                                                                  ownership.
</Table>

*    The 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 Class A, Class B and Class C
     shares. The Fund has also adopted a separate shareholder servicing plan to
     pay for servicing-related expenses related to Class Y shares. Because these
     fees are paid out of the 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.

SHOULD YOU PURCHASE CLASS A, CLASS B OR 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 qualify for a waiver of the sales charge, Class A shares will
be the best option.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.20
<Page>

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 1% 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 advisor or
investment professional.

For more information, see the SAI.

PURCHASING SHARES

Financial intermediaries 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 Fund, or the financial intermediary through which you are investing in the
Fund, may not be able to open an account for you. If the Fund or if the
financial intermediary 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.

TO PURCHASE SHARES WITH A FINANCIAL INTERMEDIARY OTHER THAN AMERIPRISE FINANCIAL
SERVICES, PLEASE CONSULT YOUR FINANCIAL INTERMEDIARY. SEE "TRANSACTIONS THROUGH
UNAFFILIATED FINANCIAL INTERMEDIARIES" FOR MORE INFORMATION. THE FOLLOWING
SECTION EXPLAINS POLICIES OF THE RIVERSOURCE FUNDS AND HOW YOU CAN PURCHASE FUND
SHARES FROM AMERIPRISE FINANCIAL SERVICES.

If you do not have an existing RiverSource fund account with Ameriprise
Financial Services, you will need to establish a brokerage account. Your
financial advisor or investment professional will help you fill out and submit
an application. Once your account is set up, you can choose among several
convenient ways to invest.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.21
<Page>

When you purchase, your order will be priced at the next NAV calculated after
your order is accepted by the Fund. If your application does not specify which
class of shares you are purchasing, we will assume you are investing in Class A
shares.

IMPORTANT: When you open an account, you must provide your correct Taxpayer
Identification Number (TIN), which is either your Social Security or Employer
Identification number.

If you do not provide and certify the correct TIN, you could be subject to
backup withholding of 28% of taxable distributions and proceeds from certain
sales and exchanges. You also could be subject to further penalties, such as:

- -  a $50 penalty for each failure to supply your correct TIN,

- -  a civil penalty of $500 if you make a false statement that results in no
   backup  withholding, and

- -  criminal penalties for falsifying information.

You also could be subject to backup withholding, if the IRS notifies us to do
so, because you failed to report required interest or dividends on your tax
return.

***  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
     sales commission to a financial intermediary making a sale with a total
     market value of $1,000,000 to $3,000,000, a sales commission up to 1.00%;
     $3,000,000 to $10,000,000, a sales commission up to 0.50%; and $10,000,000
     or more, a sales commission up to 0.25%.

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 this Fund, and

- -  Previous investments you and members of your primary household group have
   made in Class A, Class B or Class C shares in this 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. For purposes of this policy a domestic partner is an individual
      who shares your primary residence and with whom you own joint property. If
      you or any member of your primary household group elects to separate from
      the primary household group (for example, by asking that account
      statements be sent to separate addresses), your assets will no longer be
      combined for purposes of reducing your sales charge.

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

- -  Individual or joint accounts held outside of a brokerage account;

- -  Individual or joint accounts held through a brokerage account;

- -  Roth and traditional IRAs, SEPs, SIMPLEs and TSCAs, provided they are
   invested in Class A, Class B or Class C shares that are 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 beneficiary;

- -  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.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.25
<Page>

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, including Ameriprise Strategic Portfolio
   Service ADVANTAGE (SPS);

- -  Investments in Class D, Class E, 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 channels or different
financial intermediaries, and you want to include those assets toward a reduced
sales charge, you must inform Ameriprise Financial Services, your financial
advisor or investment professional in writing about the other accounts when
placing your purchase order. When placing your purchase order, you must provide
your most recent account statement and contact information regarding the other
accounts. A financial intermediary other than Ameriprise Financial Services may
require additional information.

UNLESS YOU PROVIDE AMERIPRISE FINANCIAL SERVICES, YOUR FINANCIAL ADVISOR OR YOUR
INVESTMENT PROFESSIONAL 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.

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

LETTER OF INTENT (LOI)

Generally, if you intend to invest $50,000 or more over a period of 13 months,
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 distributor. 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.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.26
<Page>

HOLDINGS MORE THAN 90 DAYS OLD. Purchases made more than 90 days before your LOI
is processed by the distributor will not be counted towards 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 "Rights of Accumulation."

NOTIFICATION OBLIGATION. If purchasing shares in a brokerage account or through
a financial intermediary, 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.

For more details on LOIs, please contact your financial advisor, investment
professional or see the SAI.

WAIVERS OF THE SALES CHARGE FOR CLASS A SHARES

Sales charges do not apply to:

- -  current or retired Board members, officers or employees of the Fund or
   Ameriprise Financial or its subsidiaries, their spouses or domestic partners,
   children and parents.

- -  current or retired Ameriprise Financial Services financial advisors,
   employees of financial advisors, their spouses or domestic partners, children

   RiverSource funds. Eligibility must be determined in advance. For assistance,
   please contact your financial advisor or investment professional.
   Participants in certain qualified plans where the initial sales charge is
   waived may be subject to a deferred sales charge of up to 4%.

- -  shareholders who have at least $1 million in RiverSource funds. If the
   investment is sold within one year after purchase, a CDSC of 1% may be
   charged.

- -  direct rollovers from Ameriprise Retirement Services, provided that the
   rollover involves a transfer of Class Y shares in this Fund to Class A shares
   in this Fund.

   -  with dividend or capital gain distributions from this Fund or from the
      same class of another RiverSource fund,

   -  through or under a wrap fee product or other investment product sponsored
      by the distributor or another authorized broker-dealer, investment
      advisor, bank or investment professional,

   -  within a segregated separate account offered by Nationwide Life Insurance
      Company or Nationwide Life and Annuity Insurance Company,

   RiverSource fund in 2000.

Policies related to reducing or waiving the sales charge may be modified or
withdrawn at any time.

UNLESS YOU PROVIDE AMERIPRISE FINANCIAL SERVICES, YOUR FINANCIAL ADVISOR OR
INVESTMENT PROFESSIONAL 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.

CLASS B AND CLASS C -- CONTINGENT DEFERRED SALES CHARGE (CDSC) ALTERNATIVE

FOR CLASS B, the CDSC is based on the sale amount and the number of years --
including the year of purchase -- 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%

</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.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.28
<Page>

Although there is no front-end sales charge when you buy Class B shares, the
distributor pays a sales commission of 4% to financial intermediaries 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 will complete its first year on Dec. 31, 2004 under calendar
year aging. However, a purchase made on Nov. 12, 2005 will complete its first
year on Nov. 11, 2006 under daily aging.

For Class B shares purchased prior to May 21, 2005, those shares will convert to
Class A shares in the ninth calendar year of ownership. For Class B shares
purchased beginning May 21, 2005, those shares 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
intermediaries 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.

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 if Ameriprise Trust Company is the
   custodian, 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.

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.

EXCHANGING/SELLING SHARES

TO SELL OR EXCHANGE SHARES HELD WITH FINANCIAL INTERMEDIARIES OTHER THAN
AMERIPRISE FINANCIAL SERVICES, PLEASE CONSULT YOUR FINANCIAL INTERMEDIARY. SEE
"TRANSACTIONS THROUGH UNAFFILIATED FINANCIAL INTERMEDIARIES" FOR MORE
INFORMATION. THE FOLLOWING SECTION EXPLAINS POLICIES OF THE RIVERSOURCE FUNDS ON
HOW YOU CAN EXCHANGE OR SELL SHARES HELD WITH AMERIPRISE FINANCIAL SERVICES.

EXCHANGES

You may exchange your Fund shares at no charge for shares of the same class of
any other publicly offered RiverSource fund. Exchanges into RiverSource
Tax-Exempt Money Market Fund may only be made from Class A shares. For complete
information on the other fund, 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.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.30
<Page>

FUNDS THAT INVEST IN SECURITIES WHICH TRADE INFREQUENTLY MAY BE VULNERABLE TO
MARKET TIMERS WHO SEEK TO TAKE ADVANTAGE OF INEFFICIENCIES IN THE SECURITIES
MARKETS. TO THE EXTENT THAT THE FUND HAS SIGNIFICANT HOLDINGS OF HIGH YIELD
SECURITIES, THE RISKS OF MARKET TIMING MAY BE GREATER FOR THE FUND THAN FOR
OTHER FUNDS. SEE "PRINCIPAL INVESTMENT STRATEGIES" FOR A DISCUSSION OF THE KINDS
OF SECURITIES IN WHICH THE FUND INVESTS. SEE "VALUING FUND SHARES" FOR A
DISCUSSION OF THE FUND'S POLICY ON FAIR VALUE PRICING, WHICH IS INTENDED, IN
PART, TO REDUCE THE FREQUENCY AND EFFECT OF MARKET TIMING.

THE FUND'S BOARD HAS ADOPTED A POLICY THAT IS DESIGNED TO DETECT AND DETER
MARKET TIMING. THE FUND SEEKS TO ENFORCE THIS POLICY 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 an institution for the benefit of its
   participants or clients, which typically engage in daily transactions, are
   not subject to this limit. The Fund seeks the assistance of financial
   intermediaries 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 intermediary. 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 intermediaries where market timing activity may not always be
   successfully detected.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.31
<Page>

Other exchange policies:

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

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

- -  Once we receive your exchange request, you cannot cancel it.

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

- -  If your shares are pledged as collateral, the exchange will be delayed until
   written approval is received from the secured party.

SELLING SHARES

You may sell your shares at any time. The payment will be mailed 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 proceeds to purchase new shares in the same account from which you
sold. If you reinvest in Class A, you will purchase the new shares at NAV rather
than the offering price 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. To take advantage of this waiver, you must send a written request
within 90 days of the date your sale request was processed and include your
account number. This privilege may be limited or withdrawn at any time and use
of this option may have tax consequences.

The Fund reserves the right to redeem in kind.

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

If you decide to sell your shares within 30 days of a telephoned-in address
change, a written request is required.

IMPORTANT: Payments sent by a bank authorization, check or money order that are
not guaranteed may take up to ten days to clear. This may cause your scheduled
arrangement or unscheduled request to fail to process if the requested amount
includes unguaranteed funds.

DISTRIBUTIONS AND TAXES

As a shareholder you are entitled to your share of the Fund's net income and net
gains. The 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

The Fund's net investment income is distributed to you as DIVIDENDS. Dividends
will generally be composed of ordinary dividend income (which may include
interest income, short-term capital gains and non-qualifying dividends). It is
unlikely the Fund will distribute qualifying dividend income, which is eligible
for preferential tax rates under current tax law. 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, or

- -  you direct the Fund to invest your distributions in the same class of any
   publicly offered RiverSource fund for which you have previously opened an
   account.

We reinvest the distributions for you 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.

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                      D.35

TAXES

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.

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. If you sell shares for less
than their cost, the difference is a capital loss. 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 within 91 days of purchase. If you buy Class A shares and within 91 days
exchange into another fund, 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
SAI.

Selling shares held in an IRA or qualified retirement account may subject you to
federal taxes, penalties and reporting requirements. Please consult your tax
advisor.

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

                  RIVERSOURCE SELECTIVE FUND -- PROXY STATEMENT
                                       F.4

ROLE AND RESPONSIBILITIES

The function of the Committee is oversight; it is American Express Financial
Corporation's responsibility to maintain appropriate systems for accounting and
internal control over financial reporting, and the Auditor's responsibility to
plan and carry out a proper audit. Specifically, American Express Financial
Corporation is responsible for: (1) the preparation, presentation and integrity
of the Fund's financial statements; (2) the maintenance of appropriate
accounting and financial reporting principles and policies; and (3) the
maintenance of internal control over financial reporting and other procedures
designed to assure compliance with accounting standards and related laws and
regulations. The Auditor is responsible for planning and carrying out an audit
consistent with applicable legal and professional standards and the terms of
their engagement letter. Nothing in the Charter shall be construed to reduce the
responsibilities or liabilities of the Fund's service providers, including the
Auditor.

Although the Committee is expected to take a detached and questioning approach
to the matters that come before it, the review of a Fund's financial statements
by the Committee is not an audit, nor does the Committee's review substitute for
the responsibilities of American Express Financial Corporation's for preparing,
or the Auditor for auditing, the financial statements. Members of the Committee
are not employees of the Fund and, in serving on this Committee, are not, and do
not hold themselves out to be, acting as accountants or auditors. As such, it is
not the duty or responsibility of the Committee or its members to conduct "field
work" or other types of auditing or accounting reviews or procedures.

In discharging their duties, the members of the Committee are entitled to rely
on information, opinions, reports, or statements, including financial statements
and other financial data, if prepared or presented by: (1) one or more officers
of the Fund whom the director reasonably believes to be reliable and competent
in the matters presented; (2) legal counsel, public accountants, or other
persons as to matters the director reasonably believes are within the person's
professional or expert competence; or (3) a Board committee of which the
director is not a member.

vice chair. A majority of the members of the Committee shall constitute a quorum
for the transaction of business at any meeting of the Committee. The action of a
majority of the members of the Audit Committee present at a meeting at which a
quorum is present shall be the action of the Committee.

or a majority of the members shall be authorized to call a meeting of the
Committee or meetings may be fixed in advance by the Committee.

legal counsel and compliance personnel of American Express Financial Corporation
and with entities that provide significant accounting or administrative services
to the Fund to discuss matters relating to the Fund's accounting and compliance
as well as other Fund-related matters.

documentation of decisions made outside of meetings by delegated authority.

PROXY STATEMENT

                                                                   Dec. 16, 2005

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

Q: WHAT ORGANIZATION CHANGES HAVE RECENTLY TAKEN PLACE?

On Sept. 30, Ameriprise Financial, Inc. (formerly American Express Financial
Corporation) became an independent company from American Express. An affiliate
of Ameriprise Financial, RiverSource Investments now serves as investment
manager to your fund. As a result, your fund's name and the names of service
providers to your fund have changed. Your statements should now reflect this new
name and the funds are now listed under RiverSource in the newspaper.

Q: WHY AM I BEING ASKED TO VOTE?

Mutual funds are required to get shareholders' votes for certain kinds of
changes, like the ones included in this proxy statement. You have a right to
vote on these changes either by mailing your proxy card, calling a toll-free
number, responding by internet or attending the shareholder meeting.

Q: IS MY VOTE IMPORTANT?

Absolutely! While the Board of Directors ("Board") for RiverSource Funds has
reviewed these changes and recommends you approve them, you have the right to
voice your opinion. Until the Fund is sure that a quorum has been reached (50%
of existing shares), it will continue to contact shareholders asking them to
vote. These efforts cost money -- so please, vote immediately.

Q: WHAT AM I BEING ASKED TO VOTE ON?

Shareholders are being asked to vote on:

- -  The merger ("Reorganization") of RiverSource Selective Fund and RiverSource
   Diversified Bond Fund.

- -  Election of Board members.

<Page>

- -  An amendment to the Fund's Articles of Incorporation to permit the Board to
   establish the minimum account value and to change the name of the corporation
   to "RiverSource" consistent with the names of the funds.

- -  An Investment Management Services Agreement (IMS Agreement) with RiverSource
   Investments, LLC.

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

Q: IF APPROVED, WHEN WILL THE MERGER HAPPEN?

If shareholders approve the merger, it will take place shortly after the
shareholder meeting. In the interim, however, it will be important for the Fund
to have a properly elected Board and an IMS Agreement that has been approved by
shareholders.

Q: WHAT DO BOARD MEMBERS DO?

Board members represent the interests of the shareholders and oversee the
management of the Fund.

Q: WHAT CHANGES ARE PROPOSED TO THE INVESTMENT MANAGEMENT SERVICES AGREEMENT?

In September, the Fund's investment manager, Ameriprise Financial, Inc.
(formerly known as American Express Financial Corporation) was spun off from its
parent company, American Express Company. The investment management functions
were then moved to RiverSource Investments, LLC, a wholly owned subsidiary of
Ameriprise Financial. While this change did not cause a termination of the IMS
Agreement, the Board determined that it would be prudent to give shareholders an
opportunity to vote on the arrangement.

Q: HOW DOES THE BOARD RECOMMEND THAT I VOTE?

After careful consideration, the Board 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 voting instruction 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 issues described in the proxy statement
or about voting procedures, please call your financial advisor or call client
services toll free at (877) 256-6085.

Introduction to Proposed Fund Merger

Aug. 31, 2005

The accompanying 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 Aug. 31, 2005. These statements have
been derived from financial statements prepared for RiverSource Diversified Bond
Fund and RiverSource Selective Fund as of Aug. 31, 2005. RiverSource Diversified
Bond Fund invests primarily in bonds and other debt securities including
securities issued by the U.S. government, corporate bonds and mortgage and
asset-backed securities. RiverSource Selective Fund invests all of its assets in
Quality Income Portfolio, a series of Income Trust, an open-end investment
company that has the same objectives as the Fund. The Portfolio invests
primarily in bonds, which are investment grade and denominated in U.S. dollars.

Under the proposed Agreement and Plan of Reorganization, Class A shares of the
RiverSource Selective Fund would be exchanged for Class A shares of the
RiverSource Diversified Bond Fund. Class B shares of the RiverSource Selective
Fund would be exchanged for Class B shares of the RiverSource Diversified Bond
Fund. Class C shares of the RiverSource Selective Fund would be exchanged for
Class C shares of the RiverSource Diversified Bond Fund. Class I shares of the
RiverSource Selective Fund would be exchanged for Class I shares of the
RiverSource Diversified Bond Fund. Class Y shares of the RiverSource Selective
Fund would be exchanged for Class Y shares of the RiverSource Diversified Bond
Fund.

The pro forma combining statements have been prepared to give effect to the
proposed transaction on the historical operations of the accounting survivor,
RiverSource Diversified Bond Fund, as if the transaction had occurred at the
beginning of the fiscal year ending Aug. 31, 2005.

Notes to Pro Forma Financial Statements

(Unaudited as to Aug. 31, 2005)

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 Aug. 31, 2005. These statements have been derived from
financial statements prepared for the RiverSource Diversified Bond Fund and
RiverSource Selective Fund as of Aug. 31, 2005.

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 Diversified Bond Fund invests primarily in bonds and other debt
securities including securities issued by the U.S. government, corporate bonds
and mortgage and asset-backed securities.

RiverSource Selective Fund invests all of its assets in Quality Income
Portfolio, a series of Income Trust, an open-end investment company that has the
same objectives as the Fund. The Portfolio invests primarily in bonds, which are
investment grade and denominated in U.S. dollars.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of RiverSource Selective Fund in exchange for Class A, B, C, I and Y
shares of RiverSource Diversified Bond Fund under U.S. generally accepted
accounting principles. The pro forma statements also reflect changes needed
regarding the change in structure of RiverSource Selective Fund. Finally, the
pro forma statements reflect estimates for the combined RiverSource Diversified
Bond 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.

Notes to Combined Investments in Securities

(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, 2005, the value of foreign securities represented 4.7%
      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, 2005, the value of these securities amounted to $185,866,451 or
      5.5% or net assets.

(e)   The share amount for Limited Liability Companies (LLC) or Limited
      Partnerships (LP) represents capital contributions.

(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)   At Aug. 31, 2005, the cost of securities purchased, including interest
      purchased, on a when-issued and/or other forward-commitment basis was
      $96,072,655.

(h)   U.S. Treasury inflation-indexed bonds are securities in which the
      principal amount is adjusted for inflation and the semiannual interest
      payments equal a fixed percentage of the inflation-adjusted principal
      amount.

(i)   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, 2005.

(j)   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, 2005.

(k)   Adjustable rate mortgage; interest rate varies to reflect current market
      conditions; rate shown is the effective rate on Aug. 31, 2005.

(l)   The following abbreviations are used in the portfolio security
      descriptions to identify the insurer of the issue:

      AMBAC   --  Ambac Assurance Corporation

      FGIC    --  Financial Guaranty Insurance Company

      FSA     --  Financial Security Assurance

      MBIA    --  MBIA Insurance Corporation

(m)   Interest rate varies either based on a predetermined schedule or to
      reflect current market conditions; rate shown is the effective rate on
      Aug. 31, 2005.

(n)   Comparable securities are held to satisfy future delivery requirements of
      the following open forward sale commitments at Aug. 31, 2005:

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.
