This document is a proxy statement for New Dimensions and a prospectus for
Large Cap Equity (each individually a "Fund" and collectively the "Funds"). It
contains the information you should know before voting on the proposal. Please
read it carefully and keep it for future reference. The address of each of the

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

How the Reorganization Will Work

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

o 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. You 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
                           long-term growth of capital.

                           growth of capital.

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 goal.

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

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

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

o 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.

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

o 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:

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

o Have RiverSource Investments, LLC (the "investment manager" or "RiverSource
  Investments") as an investment adviser.

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

o Have the same distribution policies.

o 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 long-term growth of
               capital.

 Buying Fund:  The Fund seeks to provide shareholders with long-term growth of
               capital.

Comparison of Investment Strategies
New Dimensions:

Until October 2005, the Fund was managed as follows:
- ----------------------------------------------------

The Fund primarily invests in common stocks showing potential for significant
growth. These companies often operate in areas where dynamic economic and
technological changes are occurring. The Fund may invest up to 30% of its total
assets in foreign investments.

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

o Identifying companies that the investment manager believes have above-average
  long-term growth potential based on:

     o Effective management,

     o Financial strength, and

     o Competitive market position; as well as

o Considering opportunities and risks by reviewing interest rate and economic
  forecasts both domestically and abroad.

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

o The security is overvalued relative to alternative investments.

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

o Political, economic, or other events could affect the company's performance.

o The investment manager wishes to minimize potential losses.

o The investment manager identifies a more attractive opportunity.

Beginning in October 2005, the Fund is managed as follows:
- ----------------------------------------------------------

Under normal market conditions, at least 80% of the Fund's net assets are
invested in equity securities of companies with a market capitalization greater
than $5 billion at the time of purchase. The Fund may invest in
income-producing equity securities, such as dividend-paying stocks, convertible
securities and preferred stocks. The Fund will provide shareholders with at
least 60 days' notice of any change in the 80% policy.

- --------------------------------------------------------------------------------
8   RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


In pursuit of the Fund's objective, the investment manager (RiverSource
Investments, LLC) will hold both growth and value companies and at times may
favor one more than the other based on available opportunities.

When optimizing for growth, the investment manager invests in companies it
believes to have above-average long-term growth potential, or technological
superiority, and it selects investments based, among other factors, on:

o Effective management.

o Financial strength.

o Competitive market or product position.

o Technological advantage relative to other companies.

When optimizing for value, the investment manager invests in companies that
appear to be undervalued by various measures or that may be temporarily out of
favor, but have good prospects for capital appreciation, and it selects
investments based, among other factors, on:

o Identifying a variety of large, well-established companies whose underlying
  fundamentals are stable, or are anticipated to become stable, or whose
  fundamentals are improving.

o Identifying stocks that are undervalued:

  o because they have one or more ratios, such as price-to-earnings or
    price-to-cash flow, that are low relative to the general market, or have a
    yield that exceeds the market,

  o because one or more of their valuation ratios are low relative to
    historical levels for the stock,

  o because one or more of their valuation ratios or other financial measures
    make that stock attractive relative to its peers, or

  o because they are undervalued relative to their intrinsic value, as
    identified by the investment manager.

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

o The security is overvalued relative to other potential investments.

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

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

o Potential losses, due to factors such as a market down-turn, can be
  minimized.

o A more attractive opportunity has been identified.

- --------------------------------------------------------------------------------


Large Cap Equity:
Under normal market conditions, at least 80% of the Fund's net assets are
invested in equity securities of companies with a market capitalization greater
than $5 billion at the time of purchase. The Fund may invest in
income-producing equity securities, such as dividend-paying stocks, convertible
securities and preferred stocks. The Fund will provide shareholders with at
least 60 days' notice of any change in the 80% policy.

In pursuit of the Fund's objective, the investment manager (RiverSource
Investments, LLC) will hold both growth and value companies and at times may
favor one more than the other based on available opportunities.

When optimizing for growth, the investment manager invests in companies it
believes to have above-average long-term growth potential, or technological
superiority, and it selects investments based, among other factors, on:

o Effective management.

o Financial strength.

o Competitive market or product position.

o Technological advantage relative to other companies.

When optimizing for value, the investment manager invests in companies that
appear to be undervalued by various measures or that may be temporarily out of
favor, but have good prospects for capital appreciation, and it selects
investments based, among other factors, on:

o Identifying a variety of large, well-established companies whose underlying
  fundamentals are stable, or are anticipated to become stable, or whose
  fundamentals are improving.

o Identifying stocks that are undervalued:

  o because they have one or more ratios, such as price-to-earnings or
    price-to-cash flow, that are low relative to the general market, or have a
    yield that exceeds the market,

  o because one or more of their valuation ratios are low relative to
    historical levels for the stock,

  o because one or more of their valuation ratios or other financial measures
    make that stock attractive relative to its peers, or

  o because they are undervalued relative to their intrinsic value, as
    identified by the investment manager.

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

o The security is overvalued relative to other potential investments.

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

- --------------------------------------------------------------------------------
10 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


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

o Potential losses, due to factors such as a market down-turn, can be
  minimized.

o A more attractive opportunity has been identified.

Both Funds:

o Unusual Market Conditions. During unusual market conditions, each of the Funds
  may 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 could prevent the Fund from
  achieving its investment objective. During these times, the investment manager
  may make frequent securities trades that could result in increased fees,
  expenses and taxes, and decreased performance.

o 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 investment manager is not required to use derivatives.

Comparison of Fundamental Policies
The Buying Fund shareholders 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:

Each Fund has 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 Buying Fund has a
policy prohibiting the issuing of senior securities, except as permitted under
the 1940 Act. Even though this is not

- --------------------------------------------------------------------------------
                           RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 11
- --------------------------------------------------------------------------------


stated as a fundamental policy of the Selling 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 331/3% 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.

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

  investment decisions that are suited to achieving the Fund's

- --------------------------------------------------------------------------------
12 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


  investment objective. Due to its active management, the Fund could
  underperform other mutual funds with similar investment objectives.

o Foreign Risk. The following are all components of foreign risk:

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

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

  Custody risk refers to the process of clearing and settling trades. It also
  covers holding securities with local agents and depositories. Low trading
  volumes and volatile prices in less developed markets make trades harder to
  complete and settle. Local agents are held only to the standard of care of
  the local market. Governments or trade groups may compel local agents to
  hold securities in designated depositories that are not subject to
  independent evaluation. The less developed a country's securities market is,
  the greater the likelihood of problems occurring. The liquidity of foreign
  investments may be more limited than for most U.S. investments, which means
  that, at times it may be difficult to sell foreign securities at desirable
  prices.

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

o 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 all securities may fluctuate, sometimes
  rapidly and unpredictably. This risk is generally greater for small and
  mid-sized companies, which tend to be more vulnerable to adverse developments.
  In addition, focus on a particular style, for example, investment in growth or
  value securities, may cause the Fund to underperformance other mutual funds if
  that style falls out of favor with the market.

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 you as a shareholder. 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 mutual 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) The management fee rate is the actual fee rate charged as of fiscal year
    ended July 31, 2005. It includes the impact of a performance incentive
    adjustment that decreased the management fee by 0.07%. Prior to November
    2005 the index which New Dimensions performance was measured for purposes of
    determining the performance incentive adjustment was the Lipper Large-Cap
    Growth Funds Index. Since November 2005, the index against which New
    Dimensions performance is measured for purposes of determining the
    performance incentive adjustment is the Lipper Large Cap Core Funds Index.
    Should this merger not be approved, there is a separate proposal to modify
    the management fee schedule. Under the new fee schedule, the projected
    management fee ratio based on average net assets as of July 31, 2005, net of
    the 0.07% PIA decrease, is 0.44%.
(d) Other expenses include an administrative services fee, a custody fee, a
    transfer agency fee, 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 fee that went into effect
    October 2005.
(e) The management fee ratio shown reflects what the ratio would be based on the
    fund's average net assets as of July 31, 2005 under the proposed management
    fee schedule. The ratio includes the impact of a performance incentive
    adjustment that decreased the management fee by 0.02%. The index against
    which the Fund's performance is measured for purposes of determining the
    performance incentive adjustment is the Lipper Large-Cap Core Funds Index.
(f) The management fee ratio shown reflects what the ratio would be under the
    proposed management fee schedule based on the combined average net assets of
    the two funds as of July 31, 2005. It includes the impact of a performance
    incentive adjustment that decreased the management fee by 0.02%. The index
    against which the Fund's performance is measured for purposes of determining
    the performance incentive adjustment is the Lipper Large-Cap Core Funds
    Index.
(g) New Dimensions is a feeder fund that is part of a master/feeder structure.
    For New Dimensions, both in this table and the following example, fund
    operating expenses include expenses charged by both the Fund and its Master
    Portfolio.

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:

o 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.

o 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.

o 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.

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

- --------------------------------------------------------------------------------
18 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


o 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.

o 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:

o 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.

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

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

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

o 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 directors, 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"):

o 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.

- --------------------------------------------------------------------------------
                           RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 19
- --------------------------------------------------------------------------------


o 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.

o 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.

o 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.

o Under Section 1223(1) of the Code, the tax 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.

o 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.

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

o 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.

o 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 assets as to which any unrealized gain or
loss is required to be recognized at the end of a taxable year (or on the
termination or transfer thereof) under federal income tax principles.

Prior to the closing of the Reorganization, the Selling Fund will, and the
Buying Fund may, declare a distribution to shareholders, which together with

- --------------------------------------------------------------------------------
20 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


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.

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

However, as of August 31, 2005, the other two rules mentioned in the
immediately preceding paragraph would not have affected the Selling Fund
directly because the Selling Fund's net realized and unrealized gains exceeded
its capital loss carryforwards and thus the Selling Fund had no pre-acquisition
"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) that would have become unavailable to offset gains or been spread over a
broader group of shareholders. However, a portion of the Buying Fund's losses
would have been lost.

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.

o Terms and Conditions of the Reorganization. The Board considered the terms and
  conditions of the Reorganization as described in the previous paragraphs.

o Tax Consequences. The Board considered the tax-free nature of the
  Reorganization.

o 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.

o Expense Ratios. The Board considered the relative expenses of the Funds. As of
  the end of each Fund's most recent fiscal year, the expense ratios for the
  Buying Fund, were higher than the expense ratios for the Selling Fund. For
  example, the Selling Fund's expense ratio for Class A shares as of July 31,
  2005, its most recent fiscal year end, was 0.96%. The Buying Fund's expense
  ratio for Class A shares as of July 31, 2005, its most recent fiscal year end
  adjusted to reflect current fees, was 1.18%. The Board considered these
  different expense ratios in light of the fact that the Funds have the same
  management and administrative fee schedules with the same breakpoints, and
  that the Selling Fund has realized additional breakpoints in its fee schedules
  because of its larger asset size. In addition, the disparity in expense ratios
  is a function of the performance incentive adjustment to the management fee
  for the Funds which, for the Buying Fund, decreased the expense ratio by
  0.02%, and for the Selling Fund, decreased the expense ratio by 0.07%. The
  Buying Fund is attracting assets such that, combined with the Selling Fund's
  assets, prior to giving effect to any performance incentive adjustment, the
  expense ratio is projected to fall in the future. 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.

o Economies of Scale. The Board considered the advantage of combining Funds that
  share similar investment objectives, styles and holdings. The

- --------------------------------------------------------------------------------
22 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


  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.

o 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.

o Dilution. The Board considered the fact that the Reorganization will not
  dilute the interests of the current shareholders.

o Performance. The Board considered the relative performance records of the
  Funds.

o 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 ______, 2005, the Selling Fund Board members, 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 ______, 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 IMS Agreement that has been approved by
shareholders.

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 twelve 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.

Shareholder Communications with the Board. Shareholders may communicate
directly with the Board by sending correspondence to Arne H. Carlson, Chair of
the Board, RiverSource Funds, 901 Marquette Avenue South, Suite 2810,
Minneapolis, MN 55402-3268. Correspondence to specific individual Board members
also may be directed to the same address. Account-specific correspondence
should be directed to RiverSource Funds, 70100 Ameriprise Financial Center,
Minneapolis, MN 55474.

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
invested in shares of one or more designated RiverSource funds.

    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.
(b) Includes the portion of compensation deferred in the amount of $60,371 from
    the Funds.
(c) Includes the portion of compensation deferred in the amount of $1,225 from
    the Fund.
(d) Includes the portion of compensation deferred in the amount of $1,716 from
    the Fund.
(e) Includes the portion of compensation deferred in the amount of $54,839 from
    the Funds.

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 (additions
are underlined, deletions are lined through):

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 $1,000 an amount determined by the Board of Directors and
set forth in the current Fund prospectus.

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 October
1, 2005, Ameriprise

- --------------------------------------------------------------------------------
32 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


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. Shareholders of each corporation will vote to change the
name of the legal entity.

- -----------------------------------------------------------------------

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.

Investment manager. On Sep. 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.

- --------------------------------------------------------------------------------
                           RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 33
- --------------------------------------------------------------------------------


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.

Performance Incentive Adjustment ("PIA") Calculation. The management fee
includes a PIA as part of the fee. The adjustment is based on the performance
of the fund compared to the performance of a group of similar funds, as
measured by a Lipper Index. The proposed modification clarifies the
circumstances where the Board may change the index for purposes of this
calculation. The provision in the current IMS Agreement will be modified to
read as follows (additions are underlined, deletions are lined through):

    If an Index ceases to be published for a period of more than 90 days,
    changes in any material respect, otherwise becomes impracticable or, in
    the discretion of the Board, is no longer appropriate to use for purposes
    of a performance incentive adjustment, for example, if Lipper reclassifies
    the Fund from one peer group to another, the Board may take action it
    deems appropriate and in the best interests of shareholders, including:
    (1) discontinuance of the performance incentive adjustment until such time
    as it approves a substitute index, or (2) adoption of a methodology to
    transition to a substitute index it has approved. no adjustment will be
    made until such time as the Board approves a substitute index.

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

- --------------------------------------------------------------------------------
34 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


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, 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

- --------------------------------------------------------------------------------
                           RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 35
- --------------------------------------------------------------------------------


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 September 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 October 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

- --------------------------------------------------------------------------------
36 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


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.

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.

- --------------------------------------------------------------------------------
                           RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 37
- --------------------------------------------------------------------------------


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 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 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

- --------------------------------------------------------------------------------
                           RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 39
- --------------------------------------------------------------------------------


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 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. New Dimensions 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.

- --------------------------------------------------------------------------------
                           RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 41
- --------------------------------------------------------------------------------


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.

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.

- --------------------------------------------------------------------------------
42 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT
- --------------------------------------------------------------------------------


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 proposal. They will vote against any
adjournment those shares that have voted against the proposal. The investment
manager will pay the costs of any additional solicitation and of any adjourned
meeting. A shareholder vote may be taken on one or more of the items in this
proxy statement prior to adjournment if sufficient votes have been received.

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.

Audit Fees. During the last two fiscal years, the aggregate fees paid to KPMG
LLP for professional services rendered for the audit of the annual financial
statements or services that are normally provided in connection with statutory
and regulatory filings for the fund were as follows:

Exhibit A

Form of Agreement and Plan of Reorganization

This Agreement and Plan of Reorganization dated as of ______, 2005 (the
"Agreement") is between AXP Dimensions Series, Inc. (the "Selling Corporation"),
a Minnesota corporation, on behalf of its series, RiverSource New Dimensions
Fund (the "Selling Fund"), and AXP Growth Series, Inc. (the "Buying
Corporation), a Minnesota corporation, on behalf of its series, RiverSource
Large Cap Equity 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.

- --------------------------------------------------------------------------------


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.

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 underlined):

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

The 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

- --------------------------------------------------------------------------------
                                       RIVERSOURCE FUNDS -- PROXY STATEMENT  B.1
- --------------------------------------------------------------------------------


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. 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 borrow 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.

- --------------------------------------------------------------------------------
B.2 RIVERSOURCE FUNDS -- PROXY STATEMENT
- --------------------------------------------------------------------------------


C. 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 331/3% 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

- --------------------------------------------------------------------------------
                                       RIVERSOURCE FUNDS -- PROXY STATEMENT  C.1
- --------------------------------------------------------------------------------


    disposition for cash on terms requiring that all or substantially all of
    the net proceeds of disposition be distributed to the shareholders in
    accordance with their respective interests within one year after the date
    of disposition;

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

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

- --------------------------------------------------------------------------------
C.2 RIVERSOURCE FUNDS -- PROXY STATEMENT
- --------------------------------------------------------------------------------


(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.

(b) "Corporation" means the issuer of the shares held by a dissenter before the
    corporate action referred to in section 302A.471, subdivision 1 or the
    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.

(d) "Interest" means interest commencing five days after the effective date of
    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.

                                       RIVERSOURCE FUNDS -- PROXY STATEMENT  C.3
- --------------------------------------------------------------------------------


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;
    (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),

- --------------------------------------------------------------------------------
C.4 RIVERSOURCE FUNDS -- PROXY STATEMENT
- --------------------------------------------------------------------------------


    a statement of the reason for withholding the remittance, and an offer to
    pay to the dissenter the amount listed in the materials if the dissenter
    agrees to accept that amount in full satisfaction. The dissenter may
    decline the offer and demand payment under subdivision 6. Failure to do so
    entitles the dissenter only to the amount offered. If the dissenter makes
    demand, subdivision 7 and 8 apply.

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

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

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

- --------------------------------------------------------------------------------
                                       RIVERSOURCE FUNDS -- PROXY STATEMENT  C.5
- --------------------------------------------------------------------------------


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.); the Fund's transfer agent, RiverSource Service Corporation
(formerly American Express Client Service Corporation); and the Fund's
custodian, Ameriprise Trust Company (formerly American Express Trust
Company). 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 Large Cap Equity Fund (the Fund) seeks to provide shareholders with
long-term growth of capital. Because any investment involves risk, achieving
this objective cannot be guaranteed.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, at least 80% of the Fund's net assets are
invested in equity securities of companies with a market capitalization greater
than $5 billion at the time of purchase. The Fund may invest in income-producing
equity securities, such as dividend paying stocks, convertible securities and
preferred stocks. The Fund will provide shareholders with at least 60 days'
notice of any change in the 80% policy.

In pursuit of the Fund's objective, the investment manager (RiverSource
Investments, LLC) will hold both growth and value companies and at times may
favor one more than the other based on available opportunities.

When optimizing for growth, the investment manager invests in companies it
believes to have above-average long-term growth potential, or technological
superiority, and it selects investments based, among other factors, on:

   o Effective management.

   o Financial strength.

   o Competitive market or product position.

   o Technological advantage relative to other companies.

When optimizing for value, the investment manager invests in companies that
appear to be undervalued by various measures or that may be temporarily out of
favor, but have good prospects for capital appreciation, and it selects
investments based, among other factors, on:

o  Identifying a variety of large, well-established companies whose underlying
   fundamentals are stable, or are anticipated to become stable, or whose
   fundamentals are improving.

o  Identifying stocks that are undervalued:

   o because they have one or more ratios, such as price-to-earnings or
     price-to-cash flow, that are low relative to the general market, or have a
     yield that exceeds the market,

   o because one or more of their valuation ratios are low relative to
     historical levels for the stock,

   o because one or more of their valuation ratios or other financial measures
     make that stock attractive relative to its peers, or

   o because they are undervalued relative to their intrinsic value, as
     identified by the investment manager.

- --------------------------------------------------------------------------------
3p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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

o  The security is overvalued relative to other potential investments.

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

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

o  Potential losses, due to factors such as a market down-turn, can be
   minimized.

o  A more attractive opportunity has been identified.

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.

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

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

PAST PERFORMANCE

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

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

o  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 "Fees 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. For purposes of the performance
calculation in the table we assumed:

o  the maximum sales charge for Class A shares,

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

o  no sales charge for Class Y shares, and

o  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 5.75% 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.

The Fund's Class A year-to-date return at June 30, 2005 was +1.59%.

The Lipper Large-Cap Core Funds Index includes the 30 largest large-cap core
funds tracked by Lipper Inc. The index's returns include net reinvested
dividends. The Fund's performance is currently measured against this index for
purposes of determining the performance incentive adjustment. See "Fund

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:

                               1 year      3 years      5 years     10 years
Class A(a)                      $688       $  928       $1,188       $1,929

(a)  Includes a 5.75% sales charge.

(b)  Includes the applicable CDSC.

(c)  Based on conversion of Class B shares to Class A shares in the ninth year
     of ownership.

You would pay the following expenses if you did not redeem your shares:

                               1 year      3 years      5 years     10 years

(a)  Includes a 5.75% sales charge.

(b)  Based on conversion of Class B shares to Class A shares in the ninth year
     of ownership.

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.

- --------------------------------------------------------------------------------
9p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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 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.

10p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


The Fund pays RiverSource Investments a fee for managing its assets. Under the
Investment Management Services Agreement (Agreement), the fee for the most
recent fiscal year was 0.57% of the Fund's average daily net assets, including
an adjustment under the terms of a performance incentive arrangement. The
adjustment is computed by comparing the Fund's performance to the performance of
an index of comparable funds published by Lipper Inc. The index against which
the Fund's performance is currently measured for purposes of the performance
incentive adjustment is the Lipper Large-Cap Core Funds Index. In certain
circumstances, the Fund's Board may approve a change in the index. The maximum
adjustment (increase or decrease) is 0.12% of the Fund's average net assets on
an annual basis. Under the Agreement, the Fund also pays taxes, brokerage
commissions, and nonadvisory expenses. A discussion regarding the basis for the
Board approving the Agreement is available in the Fund's most recent shareholder
report.

Portfolio Manager(s). The portfolio managers responsible for the day-to-day
management of the Fund are:

Robert Ewing, CFA, Portfolio Manager

o  Managed the Fund since 2004.

o  Joined RiverSource Investments (previously American Express Financial
   Corporation (AEFC)) in 2002.

o  Prior to that, Analyst and Portfolio Manager at Fidelity Investments from
   1990 to 2002.

o  Began investment career in 1988.

o  BS, Boston College Carroll School of Management.

Nick Thakore, Portfolio Manager

o  Managed the Fund since 2004.

Mr. Thakore provides direct day-to-day management for approximately one-third of
the portfolio optimizing for growth. Mr. Ewing provides direct day-to-day
management for approximately one-third of the portfolio optimizing for value.
Messrs. Ewing and Thakore coordinate day-to-day management of the remainder of
the portfolio, allocating approximately one-third of the portfolio among a team
of research analysts who select investments in their allocations based on the
sectors that they cover. These allocations are generally consistent with the
sector weightings of the S&P 500 Index, an unmanaged index of common stocks, but
allocations may vary.

The SAI provides additional information about portfolio manager compensation,
management of other accounts and ownership of shares in the Fund.

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

Distribution Services. Ameriprise Financial Services, Inc., 70100 Ameriprise
Financial Center, Minneapolis, Minnesota 55474 (the distributor or Ameriprise
Financial Services), provides underwriting and distribution services to the
RiverSource funds. Under the Distribution Agreement and related distribution and
shareholder servicing plan(s), the distributor receives distribution and
shareholder servicing fees. The distributor pays a portion of these fees to
financial advisors and retains a portion of these fees to support its
distribution and shareholder servicing activity. For third party sales, the
distributor re-allows a portion of these fees to the financial intermediaries
that sell Fund shares and provide services to shareholders, and retains a
portion of these fees to support its distribution and shareholder servicing
activity. Fees paid by the Fund for these services are set forth under
"Distribution (12b-1) fees" in the expense table under "Fees and Expenses." More
information on how these fees are used is set forth under "Investment Options"
and in the SAI. The distributor also administers any sales charges paid by an
investor at the time of purchase or at the time of sale (deferred sales charge).
See "Shareholder Fees (fees paid directly from your investment)" under "Fees and
Expenses" for the scheduled sales charge of each share class. See "Buying and
Selling Shares" for variations in the scheduled sales charges, and for how these
sales charges are used by the distributor. See "Other Investment Strategies and
Risks" for Fund policy regarding directed brokerage.

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

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 cash 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.

From time to time, RiverSource Investments and its affiliates may make other
payments, including non-cash compensation, to financial intermediaries to the
extent permitted by law, including providing 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 operates under an order from the
Securities and Exchange Commission that permits RiverSource Investments, subject
to the approval of the Board, to appoint a subadviser or change the terms of a
subadvisory agreement for the Fund without first obtaining shareholder approval.
The order permits the Fund to 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.

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.

15p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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.

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 than 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

- --------------------------------------------------------------------------------
16p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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.

Investment options summary

The Fund offers different classes of shares. There are differences among the
fees and expenses for each class. Not everyone is eligible to buy every class.
After determining which classes you are eligible to buy, decide which class best
suits your needs. Your financial advisor or investment professional can help you
with this decision.

*  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.

17p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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.

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:

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

- --------------------------------------------------------------------------------
18p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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

o  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.

How to determine the correct TIN

For this type of account:          Use the Social Security or Employer

SALES CHARGES

Class A -- initial sales charge alternative

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

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:

o  Your current investment in this Fund, and

o  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.

   o 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:

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

o  Individual or joint accounts held through a brokerage account;

o  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;

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

o  Revocable trust accounts for which you or a member of your primary household
   group, individually, is the beneficiary;

o  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

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

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

o  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);

o  Investments in Class A shares where the sales charge is waived, for example,
   purchases through wrap accounts, including Ameriprise Strategic Portfolio
   Service Advantage (SPS);

o  Investments in Class D, Class E, or Class Y shares;

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

o  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.

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:

o  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.

o  current or retired Ameriprise Financial Services financial advisors,
   employees of financial advisors, their spouses or domestic partners, children
   and parents.

o  portfolio managers employed by subadvisers of the RiverSource funds,
   including their spouses or domestic partners, children and parents.

o  registered representatives and other employees of financial intermediaries
   having a sub-distribution agreement with the distributor, including their
   spouses, domestic partners, children and parents.

o  qualified employee benefit plans offering participants daily access to
   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%.

o  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.

o  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.

o  purchases made:

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

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

   o through American Express Personal Trust Services' Asset-Based pricing
     alternative, provided by American Express Bank, FSB.

o  shareholders whose original purchase was in a Strategist fund merged into a
   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:

If the sale is made during the:                 The CDSC percentage rate is:*
First year                                                   5%
Second year                                                  4%
Third year                                                   4%
Fourth year                                                  3%
Fifth year                                                   2%
Sixth year                                                   1%
Seventh year                                                 0%

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

Although there is no front-end sales charge when you buy Class B shares, the
distributor pays a sales commission of 4% to financial 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:

o  in the event of the shareholder's death,

o  held in trust for an employee benefit plan, or

o  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:

   o at least 59 1/2 years old AND

   o 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

   o 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. 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.

- --------------------------------------------------------------------------------
25p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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:

o  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.

o  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.

o  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.

Other exchange policies:

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

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

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

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

o  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.

- --------------------------------------------------------------------------------
26p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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.

transactions if reasonable security measures are followed to validate the
investor's identity. The Fund may modify or discontinue electronic privileges at
any time for any shareholder without prior notice as deemed necessary and in the
best interest of the Fund.

29p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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
may be composed of qualifying dividend income, which is eligible for
preferential tax rates under current tax law, as well as other ordinary dividend
income, which may include non-qualifying dividends, interest income and
short-term capital gains. 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:

o  you request distributions in cash, or

o  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.

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.

- --------------------------------------------------------------------------------
30p   ---   RIVERSOURCE LARGE CAP EQUITY FUND   ---   2005 PROSPECTUS


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.

  in such activities;

o An understanding of internal controls and procedures for financial reporting;
  and

F.4 RIVERSOURCE FUNDS -- PROXY STATEMENT
- --------------------------------------------------------------------------------


The Committee shall have the resources and authority appropriate to discharge
its responsibilities, including appropriate funding, as determined by the
Committee, for payment of compensation to the Auditor for the purpose of
conducting the audit and rendering their audit report, the authority to retain
and compensate special counsel and other experts or consultants as the
Committee deems necessary, and the authority to obtain specialized training for
Committee members, at the expense of the Fund, as appropriate.

The Committee may delegate any portion of its authority, including the
authority to grant pre-approvals of audit and permitted non-audit services to
one or more members. Any decisions of the member to grant pre-approvals shall
be presented to the Committee at its next regularly scheduled meeting.

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


- --------------------------------------------------------------------------------
                                       RIVERSOURCE FUNDS -- PROXY STATEMENT  F.5
- --------------------------------------------------------------------------------


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.

Operations
The Board shall adopt and approve this Charter and may amend it on the Board's
own motion. The Committee shall review this Charter at least annually and
recommend to the full Board any changes the Committee deems appropriate.

The Committee may select one of its members to be the chair and may select a
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.

The Committee shall meet on a regular basis and at least four times annually
and is empowered to hold special meetings as circumstances require. The
Chairperson 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.

The agenda shall be prepared under the direction and control of the
Chairperson.

The Committee shall ordinarily meet in person; however, members may attend
telephonically, and the Committee may act by written consent, to the extent
permitted by law and by the Fund's bylaws.

The Committee shall have the authority to meet privately and to admit
non-members individually. The Committee may also request to meet with internal
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.

The Committee shall prepare and retain minutes of its meetings and appropriate
documentation of decisions made outside of meetings by delegated authority.

The Committee shall evaluate its performance at least annually.

                                 Proxy Statement

                                                               December 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:

o The merger ("Reorganization") of RiverSource New Dimensions Fund and
  RiverSource Large Cap Equity Fund.

o Election of Board members.

o 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.

o 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, or otherwise affect its terms and conditions,
the Board determined that it would be prudent to give shareholders an
opportunity to vote on the new arrangement. The new agreement also clarifies
the circumstances under which the Board may change an index for purposes of
calculating a performance incentive adjustment.

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:

o By mail with the enclosed proxy card

o By telephone

o By web site

o 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.

                       COMBINED PROXY STATEMENT/PROSPECTUS

                               DATED DEC. 16, 2005

This document is a proxy statement for Stock and a prospectus for Disciplined
Equity (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
                  growth of capital.

   BUYING FUND:   The Fund seeks to provide shareholders with long-term capital
                  growth.

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
prospectus. Any representation to the contrary is a criminal offense.

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
                 growth of capital.

   BUYING FUND:  The Fund seeks to provide shareholders with long-term capital
                 growth.

COMPARISON OF INVESTMENT STRATEGIES STOCK:

The Fund's assets primarily are invested in common stocks and securities
convertible into common stocks. Under normal market conditions, at least 80% of
the Fund's net assets are invested in these securities. In pursuit of its income
objective, the Fund will invest in income-producing equity securities (such as
convertible securities and preferred stocks) and short-term debt instruments
(such as commercial paper). The Fund will provide shareholders with at least 60
days' notice of any change in the 80% policy.

In pursuit of the Fund's objective, the investment manager uses two different
approaches to the selection of equity investments.

With respect to approximately 50% of the Fund's portfolio, the investment
manager uses a traditional stock selection methodology and chooses investments
by:

- -  Considering opportunities and risks by reviewing overall market conditions
   and industry outlook.

- -  Identifying market trends that the investment manager believes will lead to
   good long-term growth potential.

- -  Identifying companies with strong, sustainable earnings growth based on:

   -  effective management, as demonstrated by overall performance,

   -  competitive market position, and

   -  financial strength.

- -  Focusing on those companies that the investment manager considers to be blue
   chips. Blue chip stocks are issued by companies with a market capitalization
   of at least $1 billion, an established management, a history of consistent
   earnings and a leading position within their respective industries.

- -  Identifying investments that contribute to portfolio diversification.

- -  Identifying income-producing securities.

                                        8
<Page>

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

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

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

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

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

With respect to approximately 50% of the Fund's portfolio, the investment
manager uses proprietary quantitative methods based on sophisticated statistical
analysis and chooses investments by:

The universe of stocks from which the investment manager selects the Fund's
investments will be those included in the Fund's benchmark, the Standard &
Poor's 500 Index (S&P 500 Index). Through extensive analysis of the domestic
equity markets, the investment manager has identified characteristics of certain
stocks that have historically outperformed their benchmarks. The Fund will hold
both growth and value stocks. Characteristics used to select stocks for the Fund
include:

- -  Superior growth characteristics such as:

   -  strong earnings growth,

   -  positive earnings that exceed expectations published by third-party
      business analysts,

   -  consistency of earnings, and

   -  strong positive price trend.

- -  Superior value characteristics based on analysis of current stock prices
   relative to estimates of future prices.

In selecting the stocks from the S&P 500 Index for the Fund's portfolio, the
investment manager employs a rigorous process for evaluating the relationship
between the risk associated with each security and its potential for positive
returns. This process includes factors such as:

- -  Limits on positions relative to the benchmark through overweighting or
   underweighting.

- -  Limits on sector and industry allocations relative to the benchmark.

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

DISCIPLINED EQUITY:

Under normal market conditions, at least 80% of the Fund's net assets are
invested in equity securities of companies listed on U.S. exchanges with market
capitalizations greater than $5 billion at the time of purchase. The Fund will
provide shareholders with at least 60 days' notice of any change in the 80%
policy.

In pursuit of the Fund's objective, the investment manager will choose equity
investments by employing proprietary quantitative methods based on sophisticated
statistical analysis.

The universe of stocks from which the investment manager selects the Fund's
investments primarily will be those included in the Fund's benchmark, the S&P
500. Through extensive analysis of the domestic equity markets, the investment
manager has identified characteristics of certain stocks that have historically
outperformed their benchmarks. The Fund will hold both growth and value stocks.
Characteristics used to select stocks for the Fund include:

- -  Superior growth characteristics such as:

   -  strong earnings growth,

   -  positive earnings that exceed expectations published by third-party
      business analysts,

   -  consistency of earnings, and

   -  strong positive price trend.

- -  Superior value characteristics based on analysis of current stock prices
   relative to estimates of future prices.

a rigorous process for evaluating the relationship between the risk associated
with each security and its potential for positive returns. This process includes

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. 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 shareholders 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:

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 Buying 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
Selling Fund, the Fund is nonetheless subject to that restriction under the
provisions of the 1940 Act.

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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       11
<Page>

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.

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 Buying Fund has a policy prohibiting loans of any part of
its assets to the investment manager, its board members and officers and to the
board members and officers of the Buying Fund. Even though this is not stated as
the fundamental policy of the Selling Fund, the Fund is nonetheless subject to
that restriction under the provisions of the 1940 Act.

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.

<Table>
<Caption>
RISK                                     STOCK         DISCIPLINED EQUITY
                                                 
Active Management Risk                     x                    x
Issuer Risk                                x                    x
Market 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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       12
<Page>

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

- -  MARKET RISK. The market value of securities may fall or fail to rise. Market
   risk may affect a single issuer, sector of the economy, industry, or the
   market as a whole. The market value of securities may fluctuate, sometimes
   rapidly and unpredictably. This risk is generally greater for small and
   mid-sized companies, which tend to be more vulnerable to adverse
   developments. In addition, focus on a particular style, for example,
   investment in growth or value securities, may cause the Fund to underperform
   other mutual funds if that style falls out of favor with the market. The
   quantitative methodology employed by the investment manager has been
   extensively tested using historical securities market data, but has only
   recently begun to be used to manage open-end mutual funds. There can be no
   assurance that the methodology will enable the Fund to achieve its objective.

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."

FEES AND EXPENSES

The following table describes the fees and expenses, adjusted to reflect current
fees, that you pay if you buy and hold shares of the Selling Fund or shares of
the Buying Fund. The table also shows pro forma expenses of the Buying Fund
assuming the proposed Reorganization had been effective during the most recent
fiscal year, adjusted to reflect current fees. If shareholders approve the
Reorganization, for a period of 12 months following implementation of the
Reorganization, the investment manager and its affiliates have agreed to waive
fees or to cap expenses of the Buying Fund sufficient to keep total expenses
within 5 basis points (0.05%) of the Selling Fund's expense ratio at the time of
the Reorganization. For a period of 5 years following the 12-month period, the
investment manager and its affiliates have agreed to waive fees or to cap
expenses of the Buying Fund at the median expense ratio of the Buying Fund's
Lipper peer group. The level of the Buying Fund's expense cap will be reviewed
and reset annually by the Buying Fund's Board. For purposes of these
calculations, the expense ratio will be determined prior to application of the
performance incentive adjustment.

NOTES TO ANNUAL FUND OPERATING EXPENSES (CONTINUED).

(d)  The management fee rate is the actual fee rate charged as of fiscal year
     ended Sept. 30, 2004. It includes the impact of a performance incentive
     adjustment fee that decreased the management fee by .03% for the most
     recent fiscal year for Stock. The index against which Stock's performance
     is measured for purposes of determining the performance incentive
     adjustment is the Lipper Large-Cap Core Funds Index.

(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 fee that went into
     effect in Oct. 2005.

(f)  The management fee ratio shown reflects what the ratio would be based on
     the Fund's average net assets as of July 31, 2005 under the proposed
     management fee schedule. The ratio includes the impact of a performance
     incentive adjustment fee that increased the management fee by .02% for the
     most recent fiscal year for Disciplined Equity. The index against which
     Disciplined Equity's performance is measured for purposes of determining
     the performance incentive adjustment is the Lipper Large-Cap Core Funds
     Index.

(g)  For Disciplined Equity, the investment manager and its affiliates have
     contractually agreed to waive certain fees and to absorb certain expenses
     until July 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, before giving effect to any performance
     incentive adjustment (.02% increase for the most recent fiscal year), will
     not exceed 1.25% for Class A, 2.04% for Class B, 2.06% for Class C, 0.93%
     for Class I and 1.06% for Class Y.

(h)  If shareholders approve the Reorganization, the investment manager and its
     affiliates have contractually agreed to waive certain fees and to absorb
     certain expenses for six years following implementation of the
     Reorganization, unless sooner terminated at the discretion of the Fund's
     Board. Any amounts waived will not be reimbursed by the Fund. Under this
     agreement, in year one, net expenses, before giving effect to any
     performance incentive adjustment (.02% increase for the most recent fiscal
     year), will not exceed 1.00% for Class A, 1.78% for Class B, 1.77% for
     Class C, 0.64% for Class I and 0.84% for Class Y. In years two through six
     after the merger, expense caps of the Buying Fund will be at the median
     expense ratio of the Buying Fund Lipper peer group reviewed annually
     by the Board.

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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       19

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.

                                       20
<Page>

- -  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.

- -  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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       21
<Page>

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.

The Buying Fund's ability to carry forward its own pre-acquisition losses, if
any, 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 this 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, such limitation would have had no impact at all as neither
the Buying Fund nor the Selling 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).

For five years beginning after the closing date, the combined fund will not be
allowed to offset gains "built in" to either fund at the time of the
Reorganization against capital losses (including capital loss carryforwards)
built in to the other fund.

The realized and unrealized gains and losses of each Fund at the time of 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.

- -  EXPENSE RATIOS. The Board considered the relative expenses of the Funds. As
   of the end of each Fund's most recent fiscal year, the expense ratios for the
   Buying Fund were higher than the expense ratios for the Selling Fund. For
   example, the Selling Fund's expense ratio for Class A shares as of Sept. 30,
   2004 fiscal year end, adjusted to reflect current fees, was 0.91%. The Buying
   Fund's expense ratio for Class A shares as of July 31, 2005, its most recent
   fiscal year end, adjusted to reflect current fees, was capped at 1.25%,
   before giving effect to any performance adjustment. After giving effect to
   the performance incentive adjustment, the Buying Fund's expense ratio for
   Class A shares as of July 31, 2005, was 1.27%. As a result, approval of the
   Reorganization may result in higher expenses for the Selling Fund. However,
   the Buying Fund is attracting assets, and its expense ratio is projected to
   fall in the future as it realizes breakpoints in management and
   administrative fee schedules. Additionally, if shareholders approve the
   Reorganization, the investment manager has agreed to cap total expenses of
   the Buying Fund as follows: for a period of 12 months following
   implementation of the Reorganization, the investment manager and its
   affiliates will waive fees or cap expenses of the Buying Fund sufficient to
   keep total expenses within 5 basis points (0.05%) of the Selling Fund's
   expense ratio at the time of the Reorganization. For a period of 5 years
   following the 12-month period, the investment manager and its affiliates will
   waive fees or cap expenses so that the Buying Fund's expense ratio is at or
   below the median expense ratio of comparable funds sold through investment
   advisers in the Buying Fund's Lipper peer group. The level of the expense cap
   will be reviewed and reset annually by the Buying Fund's Board. For purposes
   of these calculations, the expense ratio will be determined prior to
   application of the PIA.

                                       23
<Page>

- -  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. In addition, if shareholders
   approve the Reorganization, the investment manager and its affiliates have
   agreed to cap total expenses of the Buying Fund as discussed in the paragraph
   on Expense Ratios.

- -  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, 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.

<Page>

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 IMS Agreement 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

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

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 October 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".

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.

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.

PERFORMANCE INCENTIVE ADJUSTMENT ("PIA") CALCULATION. The management fee
includes a PIA as part of the fee. The adjustment is based on the performance of
the fund compared to the performance of a group of similar funds, as measured by
a Lipper Index. The proposed modification clarifies the circumstances where the
Board may change the index. The provision in the current IMS Agreement will be
modified to read as follows ([Underline]additions are underlined[/Underline],
[Strikethrough]deletions are lined through[/Strikethrough]):

          If an Index ceases to be published for a period of more than 90 days,
          changes in any material respect, otherwise becomes impracticable

          performance incentive adjustment until such time as it approves a
          substitute index, or (2) adoption of a methodology to transition to a

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, 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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       37
<Page>

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.

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

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       38
<Page>

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 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.

                                       39

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 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 Board members 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 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. Stock 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.

                                       41
<Page>

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.

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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       42
<Page>

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.

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 Stock Series, Inc. (the "Selling Corporation"), a
Minnesota corporation, on behalf of its series, RiverSource Stock Fund (the
"Selling Fund"), and AXP Growth Series, Inc. (the "Buying Corporation), a
Minnesota corporation, on behalf of its series, RiverSource Disciplined Equity
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.

          the Selling Fund shareholders in exchange for their shares of the

          of the shares received by the Selling Fund shareholders will be the
          same as the holding period and the basis of the shares of the Selling
          Fund surrendered in the exchange; (iv) the holding period and the
          basis of the assets acquired by the Buying Fund will be the same as
          the holding period and the basis of the assets to the Selling Fund
          immediately prior to the Reorganization.

     e.   Opinion of Counsel. The Buying Corporation will have received an
          opinion of counsel for the Selling Corporation, dated as of the
          Closing, to the effect that: (i) the Selling Corporation is a
          corporation duly organized and validly existing under the laws of the
          state of Minnesota; (ii) the Selling Fund is a series of the Selling
          Corporation, an open-end investment company registered under the 1940

          Corporation.

          investment income excludable from gross income under Section 103 of
          the Code over (y) the Selling Fund's deductions disallowed under
          Sections 265 and 171 of the Code, (ii) all of the Selling Fund's
          investment company taxable income as defined in Section 852 of the
          Code (in each case computed without regard to any deduction for
          dividends paid) and (iii) all of the Selling Fund's net capital gain
          realized (after reduction

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       A.8

          for any capital loss carryover), in each case for the current taxable
          year (which will end on the Closing date) and any preceding taxable
          years for which such a dividend is eligible to be made under Section

          correct and that there have been no material adverse changes in the
          financial condition, results of operations, business, properties or

               state regulatory authorities will have been obtained.

     d.   Tax Opinion. The Selling Corporation will have received the opinion of
          Ropes & Gray LLP dated as of the Closing, as to the federal income tax
          consequences of the Reorganization to the Selling Fund and its
          shareholders. For purposes of rendering their opinion, Ropes & Gray
          LLP may rely, as to factual matters, upon the statements made in this

          or loss upon the transfer of the assets of the Selling Fund to, and
          assumption of its liabilities by, the Buying Fund in exchange for
          shares of the Buying Fund and upon the distribution of the shares to
          the Selling

                                       A.9
<Page>

          Fund shareholders in exchange for their shares of the Selling Fund;
          (ii) the shareholders of the Selling Fund who receive shares of the
          Buying Fund in the Reorganization will not recognize any gain or loss
          on the exchange of their shares of the Selling Fund for the shares of
          the Buying Fund; (iii) the holding period and the basis of the shares

          surrendered in the exchange; (iv) the holding period and the basis of
          the assets acquired by the Buying Fund will be the same as the holding

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

          opinion of counsel for the Buying Corporation, dated as of the
          Closing, to the effect that: (i) the Buying Corporation is a
          corporation duly organized and validly existing under the laws of the
          state of Minnesota; (ii) the Buying Fund is a series of the Buying

          prior to the Closing by notice to the Buying Corporation if a material
          condition to its performance or a material covenant of the Buying
          Corporation on behalf of the Buying Fund is not fulfilled on or before
          the date specified for its fulfillment or a material breach of this
          Agreement is made by the Buying Corporation on behalf of the Buying
          Fund and is not cured.

     d.   The Buying Corporation may terminate this Agreement at any time prior

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 underlined):

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

                    RIVERSOURCE STOCK 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. 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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       B.2
<Page>

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.

C. 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.

                                       B.3
<Page>

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.

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 STOCK 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

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       C.2

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;

                                       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.); the Fund's transfer agent, RiverSource Service
Corporation (formerly American Express Client Service Corporation); and the
Fund's custodian, Ameriprise Trust Company (formerly American Express Trust
Company). 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 Disciplined Equity Fund (the Fund) seeks to provide shareholders
with long-term capital growth. Because any investment involves risk, achieving
this objective cannot be guaranteed.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, at least 80% of the Fund's net assets are
invested in equity securities of companies listed on U.S. exchanges with market
capitalizations greater than $5 billion at the time of purchase. The Fund will
provide shareholders with at least 60 days' notice of any change in the 80%
policy.

In pursuit of the Fund's objective, the investment manager (RiverSource
Investments, LLC) will choose equity investments by employing proprietary
quantitative methods based on sophisticated statistical analysis.

The universe of stocks from which the investment manager selects the Fund's
investments primarily will be those included in the Fund's benchmark, the S&P
500. Through extensive analysis of the domestic equity markets, the investment
manager has identified characteristics of certain stocks that have historically
outperformed their benchmarks. The Fund will hold both growth and value stocks.
Characteristics used to select stocks for the Fund include:

- -  Superior growth characteristics such as:

   -  strong earnings growth,

   -  positive earnings that exceed expectations published by third-party
      business analysts,

   -  consistency of earnings, and

   -  strong positive price trend.

- -  Superior value characteristics based on analysis of current stock prices
   relative to estimates of future prices.

In selecting the stocks for the Fund's portfolio, the investment manager employs
a rigorous process for evaluating the relationship between the risk associated
with each security and its potential for positive returns. This process includes
factors such as:

- -  Limits on positions relative to the benchmark through overweighting or
   underweighting.

- -  Limits on sector and industry allocations relative to the benchmark.

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

PRINCIPAL RISKS

This Fund is designed for investors with above-average risk tolerance. 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.

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

MARKET RISK. The market value of securities may fall or fail to rise. Market
risk may affect a single issuer, sector of the economy, industry, or the market
as a whole. The market value of securities may fluctuate, sometimes rapidly and
unpredictably. This risk is generally greater for small and mid-sized companies,
which tend to be more vulnerable to adverse developments. In addition, focus on
a particular style, for example, investment in growth or value securities, may
cause the Fund to underperform other mutual funds if that style falls out of
favor with the market. The quantitative methodology employed by the investment
manager has been extensively tested using historical securities market data, but
has only recently begun to be used to manage open-end mutual funds. There can be
no assurance that the methodology will enable the Fund to achieve its objective.

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 "Fees 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. 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.

                                       D.5
<Page>

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.

During the period shown in the bar chart, the highest return for a calendar
quarter was +9.77% (quarter ended Dec. 31, 2004) and the lowest return for a
calendar quarter was -3.05% (quarter ended Sept. 30, 2004).

The 5.75% 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.

The Fund's Class A year-to-date return at June 30, 2005 was -0.15%.

(b)  Measurement period started May 1, 2003.

The Standard & Poor's 500 Index (S&P 500 Index), an unmanaged index of common
stocks, is frequently used as a general measure of market performance. The index
reflects reinvestment of all distributions and changes in market prices, but
excludes brokerage commissions or other fees.

The Lipper Large-Cap Core Funds Index includes the 30 largest large-cap core
funds tracked by Lipper Inc. The index's returns include net reinvested
dividends. The Fund's performance is currently measured against this index for
purposes of determining the performance incentive adjustment. See "Fund
Management and Compensation" for more information.

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

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                       D.9
<Page>

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 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.

FUND MANAGEMENT AND COMPENSATION

INVESTMENT MANAGER

RiverSource Investments, LLC (the investment manager or RiverSource
Investments), 200 Ameriprise Financial Center, Minneapolis, Minnesota 55474, is
the investment manager to the RiverSource funds, and is a wholly-owned
subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Ameriprise
Financial is a financial planning and financial services company that has been
offering solutions for clients' asset accumulation, income management and
protection needs for more than 110 years. In addition to managing investments
for all of the RiverSource funds, RiverSource Investments manages investments
for itself and its affiliates. For institutional clients, RiverSource
Investments and its affiliates provide investment management and related
services, such as separate account asset management, institutional trust and
custody, and employee benefit plan administration, as well as other investment
products. For all of its clients, RiverSource Investments seeks to allocate
investment opportunities in an equitable manner over time. See the SAI for more
information.

The Fund pays RiverSource Investments a fee for managing its assets. Under the
Investment Management Services Agreement (Agreement), the fee for the most
recent fiscal year was 0.62% of the Fund's average daily net assets, including
an adjustment under the terms of a performance incentive arrangement. The
adjustment is computed by comparing the Fund's performance to the performance of
an index of comparable funds published by Lipper Inc. The index against which
the Fund's performance is currently measured for purposes of the performance
incentive adjustment is the Lipper Large-Cap Core Funds Index. In certain
circumstances, the Fund's Board may approve a change in the index. The maximum
adjustment (increase or decrease) is 0.12% of the Fund's average net assets on
an annual basis. Under the Agreement, the Fund also pays taxes, brokerage
commissions, and nonadvisory expenses. A discussion regarding the basis for the
Board approving the Agreement is available in the Fund's most recent shareholder
report.

Minneapolis, Minnesota 55474, provides or compensates others to provide

<Page>

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

DISTRIBUTION SERVICES. Ameriprise Financial Services, Inc., 70100 Ameriprise
Financial Center, Minneapolis, Minnesota 55474 (the distributor or Ameriprise
Financial Services), provides underwriting and distribution services to the
RiverSource funds. Under the Distribution Agreement and related distribution and
shareholder servicing plan(s), the distributor receives distribution and
shareholder servicing fees. The distributor pays a portion of these fees to
financial advisors and retains a portion of these fees to support its
distribution and shareholder servicing activity. For third party sales, the
distributor re-allows a portion of these fees to the financial intermediaries
that sell Fund shares and provide services to shareholders, and retains a
portion of these fees to support its distribution and shareholder servicing
activity. Fees paid by the Fund for these services are set forth under
"Distribution (12b-1) fees" in the expense table under "Fees and Expenses." More
information on how these fees are used is set forth under "Investment Options"
and in the SAI. The distributor also administers any sales charges paid by an
investor at the time of purchase or at the time of sale (deferred sales charge).
See "Shareholder Fees (fees paid directly from your investment)" under "Fees and
Expenses" for the scheduled sales charge of each share class. See "Buying and
Selling Shares" for variations in the scheduled sales charges, and for how these
sales charges are used by the distributor. See "Other Investment Strategies and
Risks" for Fund policy regarding directed brokerage.

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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                      D.14
<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, 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 operates under an order from the
Securities and Exchange Commission that permits RiverSource Investments, subject
to the approval of the Board, to appoint a subadviser or change the terms of a
subadvisory agreement for the Fund without first obtaining shareholder approval.
The order permits the Fund to 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.

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.

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.

*  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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT

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.

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.

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.

SALES CHARGES

CLASS A -- INITIAL SALES CHARGE ALTERNATIVE

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

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

 **  Offering price includes the sales charge.

***  Although there is no sales charge for purchases with a total market value
     over $1,000,000, and therefore no re-allowance, the distributor may pay a
     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.

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);

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                      D.24
<Page>

- -  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.

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."

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

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

- -  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.

- -  purchases made:

   -  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

      advisor, bank or investment professional,

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                      D.26

   -  through American Express Personal Trust Services' Asset-Based pricing
      alternative, provided by American Express Bank, FSB.

- -  shareholders whose original purchase was in a Strategist fund merged into a
   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%
Seventh year                                                    0%
</Table>

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

Although there is no front-end sales charge when you buy Class B shares, the
distributor pays a sales commission of 4% to financial 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. 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.

                    RIVERSOURCE STOCK FUND -- PROXY STATEMENT
                                      D.29
<Page>

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.

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.

                                      D.30
<Page>

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
may be composed of qualifying dividend income, which is eligible for
preferential tax rates under current tax law, as well as other ordinary dividend
income, which may include non-qualifying dividends, interest income and
short-term capital gains. 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 STOCK FUND -- PROXY STATEMENT
                                      D.34
<Page>

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 STOCK FUND -- PROXY STATEMENT

<Page>

to grant pre-approvals of audit and permitted non-audit services to one or more
members. Any decisions of the member to grant pre-approvals shall be presented
to the Committee at its next regularly scheduled meeting.

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.

PROXY STATEMENT

                                                               December 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 Stock Fund and RiverSource
   Disciplined Equity 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. The agreement also clarifies the
circumstances under which the Board may change an index for purposes of
calculating a performance incentive adjustment.

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

July 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 July 31, 2005. These statements have
been derived from financial statements prepared for RiverSource Large Cap Equity
Fund and RiverSource New Dimensions Fund as of July 31, 2005. RiverSource Large
Cap Equity Fund invests primarily in equity securities with a market
capitalization greater than $5 billion at the time of purchase. RiverSource New
Dimensions Fund invests all of its assets in Growth Trends Portfolio, a series
of Growth Trust, an open-end investment company that has the same objectives as
the Fund. The Portfolio invests primarily in common stocks showing potential for
significant growth and operating in areas where economic or technological
changes are occurring.

Under the proposed Agreement and Plan of Reorganization, Class A shares of the
RiverSource New Dimensions Fund would be exchanged for Class A shares of the
RiverSource Large Cap Equity Fund. Class B shares of the RiverSource New
Dimensions Fund would be exchanged for Class B shares of the RiverSource Large
Cap Equity Fund. Class C shares of the RiverSource New Dimensions Fund would be
exchanged for Class C shares of the RiverSource Large Cap Equity Fund. Class I
shares of the RiverSource New Dimensions Fund would be exchanged for Class I
shares of the RiverSource Large Cap Equity Fund. Class Y shares of the
RiverSource New Dimensions Fund would be exchanged for Class Y shares of the
RiverSource Large Cap Equity 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 Large Cap Equity Fund, as if the transaction had occurred at the
beginning of the fiscal year ending July 31, 2005.

RiverSource Stock Fund

Introduction to Proposed Fund Merger

July 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 July 31, 2005. These statements have
been derived from financial statements prepared for RiverSource Disciplined
Equity Fund and RiverSource Stock Fund as of July 31, 2005. RiverSource
Disciplined Equity Fund invests primarily in equity securities of companies
listed on U.S. exchanges with market capitalizations greater than $5 billion at
the time of purchase. RiverSource Stock Fund invests all of its assets in Equity
Portfolio, a series of Growth and Income Trust, an open-end investment company
that has the same objectives as the Fund. The Portfolio invests primarily in
income-producing equity securities (such as convertible securities and preferred
stocks) and short-term debt instruments (such as commercial paper).

Under the proposed Agreement and Plan of Reorganization, Class A shares of the
RiverSource Stock Fund would be exchanged for Class A shares of the RiverSource
Disciplined Equity Fund. Class B shares of the RiverSource Stock Fund would be
exchanged for Class B shares of the RiverSource Disciplined Equity Fund. Class C
shares of the RiverSource Stock Fund would be exchanged for Class C shares of
the RiverSource Disciplined Equity Fund. Class I shares of the RiverSource Stock
Fund would be exchanged for Class I shares of the RiverSource Disciplined Equity
Fund. Class Y shares of the RiverSource Stock Fund would be exchanged for Class
Y shares of the RiverSource Disciplined Equity Fund.

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

RiverSource Disciplined Equity Fund

RiverSource Stock Fund

Notes to Pro Forma Financial Statements

(Unaudited as to July 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 July 31, 2005. These statements have been derived from
financial statements prepared for the RiverSource Disciplined Equity Fund and
RiverSource Stock Fund as of July 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 Disciplined Equity Fund invests primarily in equity securities of
companies listed on U.S. exchanges with market capitalizations greater than $5
billion at the time of purchase.

RiverSource Stock Fund invests all of its assets in Equity Portfolio, a series
of Growth and Income Trust, an open-end investment company that has the same
objectives as the Fund. The Portfolio invests primarily in income-producing
equity securities (such as convertible securities and preferred stocks) and
short-term debt instruments (such as commercial paper).

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

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

The pro forma statement of operations give effect to the proposed transaction on
the historical operations of the accounting survivor, RiverSource Disciplined
Equity Fund, as if the transaction had occurred at the beginning of the year
presented.

2. PRO FORMA ADJUSTMENTS

(a)   To reflect adjustments needed regarding the change in structure of
      RiverSource Stock Fund from a feeder fund presentation into a reporting
      format comparable with the accounting survivor.

(b)   To reflect the increase in investment management services fee due to the
      Reorganization.

(c)   To reflect the increase in administrative services fees due to the
      Reorganization and to include the impact of the revised administrative
      services agreement.

(d)   To reflect the decrease in custodian fees due to the Reorganization.

(e)   To adjust for the change in the compensation of board members due to the
      Reorganization.

(f)   To reflect the reduction in audit fees due to the Reorganization.

(g)   To adjust the expense reimbursement to include the impact of the agreement
      by RiverSource Investments, LLC and its affiliates to waive certain fees
      and to absorb certain expenses following the merger.

3. CAPITAL SHARES

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
