SECTION B - FUND PROPOSALS

PROPOSAL 1: ELECTION OF BOARD MEMBERS
(Applies to: ALL FUNDS)

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. This policy
does not apply to Ms. Jones who must retire after her 75th birthday.

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

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

The Board Effectiveness Committee's charter, Exhibit A, 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 B. 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 D.

During the year 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. Information on
compensation paid to Board members by individual funds is shown in Section E.

     member compensation is a combination of a base fee and meeting fees.
     Because the spin-off of Ameriprise Financial from American Express Company
     necessitated 5 additional meetings, Ameriprise Financial reimbursed the
     funds $23,500 for each member to cover those additional meetings. Mr.

     2005 and therefore are not included in the table.

FUND OFFICERS. In addition to Mr. Truscott, the fund's other executive officers
are:

LESLIE L. OGG, age 67. Vice president, general counsel and secretary since 1978.
President of Board Services Corporation.

JEFFREY P. FOX, age 50. Treasurer since 2002. Vice President - Investment
Accounting of Ameriprise Financial.

PAULA R. MEYER, age 51. President since 2002. Senior Vice President - Mutual
Funds, RiverSource Investments.

Officers serve at the pleasure of the Board. Officers are paid by Ameriprise
Financial, Inc., RiverSource Investments or Board Services Corporation. During
the last fiscal year, no officer earned more than $60,000 from any fund.

PROPOSAL 2: APPROVE OR REJECT AN AMENDMENT TO THE ARTICLES OF INCORPORATION

(Applies to: ALL FUNDS EXCEPT CALIFORNIA TAX-EXEMPT, MASSACHUSETTS TAX-EXEMPT,
MICHIGAN TAX-EXEMPT, MINNESOTA TAX-EXEMPT, NEW YORK TAX-EXEMPT AND OHIO
TAX-EXEMPT)

Every fund is organized under state law. Each RiverSource fund, except those
listed under the heading above, 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

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       13
<Page>

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. For certain funds, the Board also made other
clarifying changes in the name of the fund. 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.
In addition, the Boards recommend that other portions of the names of some of
the corporations be changed to more clearly identify the types of funds included
in that corporation. 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. You can determine which corporation your fund is part of by
referring to page 1 of this proxy statement. Similar name changes will be made
for the Massachusetts business trusts by action of the Board as permitted by the
Declaration of Trust.

PROPOSAL 3: APPROVE OR REJECT AN INVESTMENT MANAGEMENT SERVICES AGREEMENT WITH
RIVERSOURCE INVESTMENTS, LLC
(Applies to: ALL FUNDS)

The fund pays fees to RiverSource Investments under an investment management
services agreement (the "IMS Agreement") for investment management services.
These services include providing the personnel, equipment and office facilities
necessary for the management of the fund's assets. Subject to the oversight of
the Board and consistent with the fund's investment policies, the investment
manager decides which 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. For some of the funds, RiverSource
Investments hires, pays and oversees a sub-adviser to perform the day-to-day
management functions. Some of the retail funds are part of master/feeder
structures. In these structures, these funds invest all of their assets in
master funds (the "portfolio") with the same investment policies as the
respective funds. For purposes of this discussion, the portfolio is referred to
as a "fund".

On Sept. 30, 2005, Ameriprise Financial became a publicly traded company and on
Oct. 1, 2005 transferred its investment management functions and IMS Agreements
to RiverSource Investments, a wholly owned subsidiary. While these transfers did
not cause a termination of the IMS Agreement, the Board determined that it would
be prudent to give shareholders an opportunity to review and vote on the
proposed new IMS Agreements reflecting these new arrangements and the changes
discussed below.

SUMMARY OF KEY CHANGES

A.  PERFORMANCE INCENTIVE ADJUSTMENT ("PIA"). The management fee for the equity
    and balanced funds includes a PIA as part of the fee calculation. The PIA
    calculation is based on the performance of the fund compared to the
    performance index of a group of comparable mutual funds compiled by Lipper,
    Inc. The proposed change clarifies the circumstances under which the Board
    may change an index for purposes of calculating the PIA.

B.  VARIABLE PORTFOLIO FUNDS. For each of the variable portfolio funds, the
    current IMS Agreement includes the provision of transfer agent services. For
    all variable portfolio funds except VP Core Equity, these services will be
    provided under a new transfer agency agreement if the proposed IMS
    Agreements are approved. In addition, the proposed IMS Agreement clarifies
    the description of allocation of expenses. For VP Core Equity, the proposed
    IMS Agreement includes a new provision authorizing the investment manager to
    subcontract for administrative or transfer agent services.

C.  FEE SCHEDULE. For certain funds only, the investment manager has proposed
    changes in the fee schedules. Please see Table B-5 to examine the fees for
    each Fund. For other funds, the fee schedules are unchanged.

D.  STANDARD OF CARE. For all funds, the investment manager will be held to a
    higher standard of care than under the current IMS Agreement (i.e., it will
    be liable for "negligence" rather than "gross negligence").

E.  CONFIDENTIALITY. The proposed IMS Agreement contains an explicit
    acknowledgement from the funds that the investment manager may be prevented
    from divulging or acting upon certain confidential information learned in
    connection with its activities, including the provision of investment advice
    to clients other than the funds. In addition, the proposed IMS Agreement
    contains additional confidentiality provisions prohibiting the funds from
    disclosing to third parties any information or advice furnished by the
    investment manager to the funds, except under limited circumstances.

F.  AMENDMENTS. The proposed IMS Agreement clarifies that, as permitted under
    applicable law, the parties may make non-material amendments or
    modifications without obtaining shareholder approval.

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 D. 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 D 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.

A.  PIA CALCULATION.

The management fee for the equity and balanced funds 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 explains 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
    [UNDERLINE]or, in the discretion of the Board, is no longer
    appropriate[/UNDERLINE] to use for purposes of a performance incentive
    adjustment, [UNDERLINE]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.[/UNDERLINE] [STRIKETHROUGH]no adjustment will be made
    until such time as the Board approves a substitute index.[/STRIKETHROUGH]

The PIA is determined by measuring the difference in a fund's performance
compared to an index of similar funds over a rolling 12-month period. Should the
Board approve the use of a substitute index, it may transition to the
substitute index by introducing it gradually over time, to avoid unintended
swings in the PIA.

B.  VARIABLE PORTFOLIO FUNDS.

    - FOR ALL VP FUNDS EXCEPT VP CORE EQUITY

    The current IMS Agreement for the variable portfolio funds includes both
    investment management services and transfer agent services. RiverSource
    Investments recommended to the Board that the transfer agent services be
    eliminated from the IMS agreement and moved to a separate agreement. This
    structure is consistent with how services are provided to the retail funds
    and will facilitate consistency in the management fee structure between
    similar retail and variable portfolio funds. The fee under the proposed IMS
    agreement will be reduced, in amounts that vary by fund, to reflect the
    elimination of the transfer agent services. If shareholders approve the
    proposal, the fund will then enter into a separate transfer agent agreement
    with RiverSource Service Corporation. The fee under that agreement will be
    uniform for all funds at an annual rate of 0.06% of average daily net
    assets.

    In addition to eliminating transfer agent services, the proposed IMS
    Agreement clarifies the description of the allocation of expenses between
    the fund and the investment manager. The change will not affect the
    allocation of expenses, but rather will eliminate an ambiguity in the
    current IMS Agreement.

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       18
<Page>

    Part One of the current IMS Agreement states that the investment manager
    will "pay or reimburse such expenses of the Fund as may be provided for in
    Part Three". The proposed IMS Agreement does not include that reference
    since there are no expenses delineated in Part Three for the investment
    manager to pay. Part Three identifies the expenses the fund will pay. The
    statement in Part One creates potential ambiguity about who does pay the
    delineated expenses.

    - FOR VP CORE EQUITY

    Unlike the other variable portfolio funds, VP Core Equity is available as an
    investment option only under certain variable annuity contracts that are no
    longer offered for sale. The current IMS Agreement for VP Core Equity
    includes the provision of administrative and transfer agent services, in
    addition to investment management services. The proposed IMS Agreement for
    VP Core Equity will continue to cover those services. However, the proposed
    IMS Agreement includes a new provision authorizing RiverSource Investments,
    at its own expense, to delegate the provision of certain services to an
    affiliate or, subject to the Board's prior approval, to enter into
    agreements with unaffiliated companies to assist the investment manager in
    performing any of the administrative or transfer agent services.

C.  FEE SCHEDULE.

RiverSource Investments recommended to the Board that the management fees under
the current IMS Agreement be changed consistent with its broader effort to
establish competitive pricing for the funds, while at the same time providing
fair compensation in light of increased costs resulting from changing regulatory
demands and intensified competition for professional talent. RiverSource
Investments proposed management fees which would result in lower management fees
for nineteen retail funds and eighteen variable portfolio funds, higher
management fees for four retail funds and two variable portfolio funds, and no
change to management fees for thirty-six retail funds and two variable portfolio
funds. RiverSource Investments believes that these changes will allow it to
maintain a high level of service to each fund and to hire and retain high
quality investment management and research personnel for each fund. In addition
to impacting current management fees, RiverSource Investments recommended
changes to certain funds' breakpoint schedules. Table B-5 shows how these
recommended changes affect your fund.

Changes to the variable portfolio funds include reduction in the management fee
for transfer agency services, which will be offset in part or in whole by a
0.06% transfer agency fee in a separate transfer agency agreement should
shareholders approve the IMS Agreement.

                    RIVERSOURCE FUNDS -- PROXY STATEMENT

Management fees are a significant component of the expenses you incur as a
shareholder. You should review your fund's prospectus for your fund's total
expenses to understand the costs you can expect to incur as a shareholder. See
"How the Proposed Fee Schedules Will Affect Total Fund Expenses" for how these
recommendations, if approved, may affect the costs you will incur as a
shareholder.

D. STANDARD OF CARE. The proposed IMS Agreement revises the standard of care to
provide that, except for bad faith, intentional misconduct or negligence in
regard to the performance of its duties pursuant to the agreement, neither the
investment manager, nor any of its respective directors, officers, partners,
principals, employees, or agents shall be liable for any acts or omissions or
for any loss suffered by the fund or its shareholders or creditors. This means
that the investment manager is held to a higher standard of care. The current
IMS Agreement provides that, except for bad faith, intentional misconduct or
gross negligence in regard to the performance of its duties pursuant to the
agreement, neither the investment manager, nor any of its respective directors,
officers, partners, principals, employees, or agents shall be liable for any
acts or omissions or for any loss suffered by the fund or its shareholders or
creditors.

E. CONFIDENTIALITY. The current IMS Agreement contains an acknowledgement by the
funds that the investment manager renders investment advice and other services
to other investment companies and persons which may or may not have investment
policies and investments similar to those of the funds. The proposed IMS
Agreement adds an explicit acknowledgement from the funds that the investment
manager may not be free to divulge to the funds or act, for the benefit of the
funds, upon confidential information learned in connection with its activities,
including the provision of investment advice to clients other than the funds.

The current IMS Agreement is silent on the funds' obligation to refrain from
divulging confidential information. The proposed IMS Agreement includes a new
provision that prohibits the funds from disclosing to third parties any
information or advice furnished to the funds by the investment manager, except
under limited circumstances.

F. AMENDMENTS. The current IMS Agreement does not address whether shareholder
approval must be obtained before non-material amendments or modifications may be
made. The proposed IMS Agreement includes a new provision clarifying that the
parties may make non-material amendments or modifications without obtaining
shareholder approval, as permitted under applicable law.

WHY RIVERSOURCE INVESTMENTS IS SEEKING TO RESTRUCTURE FUND MANAGEMENT FEES.

RiverSource Investments generally believes that each fund should have a total
expense ratio at or below the median of a group of comparable funds sold through
investment advisers (peer group). Working with the Board, it developed an
approach for carrying out this pricing philosophy whereby it would use the fee
structures that are set forth below, together with expense caps or waivers to
keep each fund at or below the median of the peer group, prior to giving effect
to any performance incentive adjustment. RiverSource Investments and the Board
have agreed to review fees annually and that if, at the time of the review, the
total expense ratio was more than .03% above the peer group median the expense
cap would be adjusted accordingly. RiverSource Investments represented to the
Board that the implementation of this pricing philosophy will enable it to
continue to provide high quality services and to continue its efforts to improve
investment performance.

Details of recommended changes are fully set forth under Table B-5. Note that
"Fee decreases" and "Fee increases" are only with respect to the management fee
schedule. See discussion under "How the Proposed Fee Schedules Will Affect Total
Fund Expenses" for more information on other changes to fund fees and expenses,
and see Table B-6 for how these changes would position each fund in comparison
to its peer group.

The factors considered by the Board in determining the reasonableness and
fairness of the fee schedules recommended by the investment manager are
described under "Basis for Recommendation of the Board."

FUND EXPENSES. Total fees and expenses the fund actually paid as well as the
fees and expenses the fund would have paid if the proposed IMS Agreement had
been in effect for the last fiscal year are shown in Table D-6.

HOW THE PROPOSED FEE SCHEDULE WILL AFFECT TOTAL FUND EXPENSES. It has become
increasingly expensive to operate mutual funds due to changing regulatory
demands and intensified competition for professional talent. RiverSource
Investments is seeking to establish a pricing philosophy with a goal of
maintaining competitive pricing for all the RiverSource funds for which
RiverSource Investments and its affiliates provide investment management, fund
administration, transfer agency, distribution and other services. Certain
changes already have been made in contracts with affiliates of RiverSource
Investments, as discussed below.

In September 2005, the Board approved changes to the administrative service fee
schedules bringing into line different pricing methodologies that had developed
among the funds. This resulted in decreased administrative services fees for a
few funds and a modest increase for most funds. The Board determined these
changes were necessary to support increased costs. However, the effect of these
increased administrative services fees for certain funds was limited, in part or
in whole by expense caps or waivers. For the variable portfolio funds,
RiverSource Investments has proposed moving transfer agent services from the IMS
Agreement to a new transfer agent agreement.

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       36

The impact of moving transfer agent fees from the IMS Agreement fee schedules
varies by fund and decreases the rate between 0.03% to 0.15% of average daily
net assets. If the recommended variable portfolio fund IMS Agreement is
approved, the Board has approved a new transfer agent agreement with a uniform
..06% transfer agent fee to be established for each variable portfolio fund,
which RiverSource Service Corporation has determined is consistent with the cost
of providing those services.

The net impact of these fee and expense changes, if shareholders approve the
recommendations, as well as fees and expenses the fund would have paid if the
proposed IMS Agreement and all other changes had been in effect for the last
fiscal year are shown in Table D-7.

With the proposed changes to the management fees, and the other changes that
have been approved by the Board, RiverSource Investments and its affiliates
represent that they will be able to:

- -  Continue efforts to improve investment performance

- -  Continue to manage the day-to-day business affairs of the funds

- -  Continue to make required investments to cover the increased costs of
   operating the funds

- -  Retain and attract highly qualified investment professionals

- -  Retain and attract additional operations and compliance personnel, and
   continue to develop technology solutions to operate in the current regulatory
   environment

- -  Maintain and improve the competitiveness of the funds generally by
   implementing a pricing philosophy that establishes median net expenses for
   the funds at or below each fund's peer group median net expenses as reviewed
   by the Board on an annual basis.

- -  Continue to offer a high level of service to fund shareholders and take steps
   to enhance those services.

- -  Seek to earn an appropriate return on investments.

COMPARISON WITH OTHER MUTUAL FUNDS. If shareholders approve the recommended
management fee changes, each RiverSource fund, with the exception of four
sub-advised funds, will be at or below the median expense ratio of its Lipper
peer group. Subadvised funds are footnoted in the table below. For the
subadvised funds that would be priced above median, the higher fees for these
funds are attributable to the fact that they primarily invest in small cap
securities and have multiple subadvisers. The Board determined that this was an
appropriate exception to the broader pricing philosophy insofar as relative
economies of scale are unlikely to be reached by any particular subadviser with
respect to its allocated portion of the fund resulting in higher management fees
paid to the subadvisers. For purposes of this comparison, median is total
expenses not more than 0.03% above the median expenses of the relevant Lipper
peer group.

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

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       41

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 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
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.

The Board also considered that it has received monthly performance reports for
the funds. The Board and its committees concluded in Sept. 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,

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       44
<Page>

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.

                                       45

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 a 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 by a Fund,
the Board will consider appropriate steps to take for that Fund.

PROPOSAL 4: APPROVE OR REJECT CHANGES IN THE SUBADVISORY AGREEMENT WITH KENWOOD
CAPITAL MANAGEMENT LLC

(Applies to: SMALL CAP ADVANTAGE, VP SMALL CAP ADVANTAGE)

Kenwood Capital Management LLC ("Kenwood") is a registered investment adviser
with particular expertise in investments in small capitalization companies.
Kenwood is an affiliate of Ameriprise Financial that acts as subadviser for the
fund under a subadvisory agreement between Kenwood and RiverSource Investments
(the "Kenwood Agreement"). RiverSource Investments recommended to the Board that
the fee schedule for the Kenwood Agreement be changed to help ensure that
Kenwood receives fees for its services that will allow it to attract and retain
high quality investment management and research personnel and to continue
efforts to improve performance for the benefit of shareholders in the future.
The proposed change in the Kenwood Agreement includes an increase in the fee as
well as the addition of a performance incentive adjustment. The fee is paid to
Kenwood by RiverSource Investments, not by the fund. This change will not affect
the cost to shareholders. A separate proposal to increase fees paid by the fund
to RiverSource Investments is discussed in Proposal 3.

TERMS OF THE CURRENT KENWOOD AGREEMENT. The current fee paid by RiverSource
Investments to Kenwood for managing fund assets is 0.35% of average daily net
assets. The complete fee schedule for the fund and other funds managed by
RiverSource Investments is found in Section D. The initial approval of the
Kenwood Agreement by shareholders was on June 16, 1999.

PROPOSED KENWOOD AGREEMENT COMPARED TO THE CURRENT KENWOOD AGREEMENT. The terms
of the proposed Kenwood Agreement are the same as the current Kenwood Agreement
except for (1) the change in the fee schedule and (2) the addition of a
performance incentive adjustment. The proposed fee schedule is as follows:

<Page>

In addition, the proposed Kenwood Agreement includes a performance incentive
adjustment. Under the performance incentive adjustment, the base fee will
increase or decrease based on the performance of Kenwood's portion of the fund
compared to the performance of the Russell 2000 Index. The fee paid to Kenwood
by RiverSource Investments will increase or decrease 3 basis points (0.03%) for
each 1% difference between the return of Class A shares of the fund and the
return of the Index. The fee will be calculated monthly over a rolling 12-month
period.

PRINCIPALS AND MANAGEMENT BOARD OF KENWOOD. Jacob E. Hurwitz and Kent A. Kelley
are the principals of Kenwood, located at 333 South 7th Street, Suite 2330,
Minneapolis, MN. The following individuals are directors of Kenwood: Jacob E.
Hurwitz, Kent A. Kelley, Ward D. Armstrong, William F. Truscott, Peter A. Gallus
and Michelle M. Keeley. Mr. Armstrong, Mr. Truscott, Mr. Gallus and Ms. Keeley
are officers of RiverSource Investments, 200 Ameriprise Financial Center,
Minneapolis, MN. RiverSource Investments, a wholly owned subsidiary of
Ameriprise Financial, owns 48.6% of Kenwood. Mr. Hurwitz and Mr. Kelley each own
a minority interest in Kenwood totaling 48.4%. Associate portfolio managers
employed by Kenwood hold the remainder of the firm's stock.

BOARD CONSIDERATIONS AND CONCLUSIONS.

At its meeting held on Sept. 8, 2005, the Board, including a majority of its
independent members, approved the proposed Kenwood Agreement for each applicable
fund and recommended its approval by shareholders. In making this determination,
the Board evaluated the nature, extent and quality of services provided by
Kenwood. This evaluation included an analysis of the resources of Kenwood as
well as those of its affiliate, Ameriprise Financial (including those
considerations discussed in Proposal 3 under "Basis for Recommendation of the
Board - Nature, Extent and Quality of Services to be Provided by Post-Spin
Ameriprise Financial (and its subsidiaries)"). The Board also examined the
investment performance of each applicable fund (see discussion in Proposal 3
under "Basis for Recommendation of the Board - Investment Performance.") The
Board observed that Kenwood has delivered solid and consistent performance for
the past three years. Based on the foregoing, the Board determined that the
nature, extent and quality of advisory services provided by Kenwood were
satisfactory. The Board also analyzed the cost of services to the funds as well
as to Kenwood. In this regard, the Board observed that the fees paid to Kenwood
under the proposed Kenwood Agreement would increase. But, the Board accorded
weight to the fact that the fees under the current Kenwood Agreement are well
below market rate for similar services. The Board also considered the total
expense ratio of each fund (see discussion in Proposal 3 under "Basis for
Recommendation of the Board - Cost of Services Provided"

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       48

for detail regarding these considerations). Additionally, the Board took into
account that the fee schedule in the proposed Kenwood Agreement includes
"breakpoints" that would be triggered as fund asset levels grow. Based on the
foregoing, the Board determined that the fees to be paid under the proposed
Kenwood Agreement for each fund would be fair and reasonable in light of the
quality of services provided.

RECOMMENDATION AND VOTE REQUIRED. The Board recommends that shareholders approve
the proposed change in the Kenwood Agreement. The change 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 change is approved, the proposed Kenwood Agreement will go into
effect as soon as practicable after the shareholder meeting. If the proposed
Kenwood Agreement is not approved, the Board will consider what steps to take.

PROPOSAL 5: APPROVE OR REJECT A SUBADVISORY AGREEMENT WITH THREADNEEDLE
INTERNATIONAL LIMITED

(Applies to: EMERGING MARKETS, EUROPEAN EQUITY, GLOBAL EQUITY, INTERNATIONAL
OPPORTUNITY, VP EMERGING MARKETS, VP INTERNATIONAL OPPORTUNITY)

Threadneedle International Limited ("Threadneedle"), a direct wholly-owned
subsidiary of Ameriprise Financial, acts as subadviser for the fund under a
subadvisory agreement between Threadneedle and RiverSource Investments (the
"Threadneedle Agreement"). In connection with the change in investment manager
described in Proposal 3, independent counsel advised the Board that it would be
prudent to seek shareholder approval of the Threadneedle Agreement as well. The
change does not affect the terms and conditions of the Threadneedle Agreement.
The subadvisory fee, which would not change, would continue to be paid to
Threadneedle by RiverSource Investments, not by the fund.

TERMS OF THE CURRENT THREADNEEDLE AGREEMENT. The fee paid by RiverSource
Investments to Threadneedle for managing fund assets is shown in the table
below. The complete fee schedule for the funds subadvised by Threadneedle is
found in Section D.

BOARD CONSIDERATIONS AND CONCLUSIONS.

At its meeting held on Sept. 8, 2005, the Board, including a majority of its
independent members, approved the proposed Threadneedle Agreement for each
applicable fund and recommended its approval by shareholders. In making this
determination, the Board evaluated the nature, extent and quality of services
provided by Threadneedle. This evaluation included an analysis of the resources
of Threadneedle as well as those of its parent, Ameriprise Financial (including
those considerations discussed in Proposal 3 under "Basis for Recommendation of
the Board - Nature, Extent and Quality of Services to be Provided by Post-Spin
Ameriprise Financial (and its subsidiaries)"). The Board noted the ability of
Threadneedle to manage assets in foreign markets. The Board also examined the
investment performance of each applicable fund (see discussion in Proposal 3
under "Basis for Recommendation of the Board - Investment Performance.") Based
on the foregoing, the Board determined that the nature, extent and quality of
advisory services provided by Threadneedle were satisfactory. The Board also
analyzed the cost of services to the funds as well as to Threadneedle. In this
regard, the Board observed that the fees paid to Threadneedle under the proposed
Threadneedle Agreement would be the same as they are now. The Board also
considered the total expense ratio of each fund (see discussion in Proposal 3
under "Basis for Recommendation of the Board - Cost of Services Provided" for
detail regarding these considerations). Additionally, the Board took into
account that the fee schedule in the proposed Threadneedle Agreement includes
"breakpoints" that would be triggered as fund asset levels grow. Based on the
foregoing, the Board determined that the fees to be paid under the proposed
Threadneedle Agreement for each fund would be fair and reasonable in light of
the quality of services provided.

RECOMMENDATION AND VOTE REQUIRED. The Board recommends that shareholders approve
the Threadneedle Agreement. The change 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 proposed
Threadneedle Agreement is not approved, the Board will consider what steps to
take.

PROPOSAL 6: APPROVE OR REJECT A SUBADVISORY AGREEMENT WITH DAVIS ADVISORS

(Applies to: FUNDAMENTAL VALUE)

Davis Advisors ("Davis") acts as subadviser for the fund under a subadvisory
agreement with RiverSource Investments (the "Davis Agreement"). Davis invests
money for many clients and, from time to time, has held more than 5% of the
voting securities of American Express Company. Immediately after the spin off
and from time to time thereafter, Davis may hold more than 5% of the voting
securities of Ameriprise Financial. Davis therefore may be considered an
affiliate of the fund. In connection with the change in investment manager
described in Proposal 3, shareholders are being asked to approve the Davis
Agreement as well. The subadvisory fee is paid to Davis by RiverSource
Investments, not by the fund. A change in the fee paid to Davis will not affect
the fee paid by the fund to RiverSource Investments. The proposed change in the
Davis Agreement will not affect the expenses of the fund or the cost to
shareholders.

TERMS OF THE CURRENT DAVIS AGREEMENT. The fee paid by RiverSource Investments to
Davis for managing fund assets is 0.45% on average daily net assets up to $100
million, 0.40% on assets from $100 million to $500 million, and 0.35 on assets
over $500 million. The complete fee schedule for the fund is found in Section D.
The Davis Agreement was approved by AEFC as sole shareholder on June 7, 2001.
Davis also manages Davis Financial Fund for which it is paid at an annual rate
based on average net assets as follows: 0.75% on the first $250 million of
average net assets; 0.65% on the next $250 million of average net assets; and
0.55% on average net assets in excess of $500 million.

PROPOSED DAVIS AGREEMENT COMPARED TO THE CURRENT DAVIS AGREEMENT. The terms of
the proposed Davis Agreement are the same as the current Davis Agreement except
for the change in the fee schedule. The proposed fee schedule is as follows:

BOARD CONSIDERATIONS AND CONCLUSIONS.

At its meeting held on Sept. 8, 2005, the Board, including a majority of its
independent members, approved the proposed Davis Agreement for the fund and
recommended its approval by shareholders. In making this determination, the
Board evaluated the nature, extent and quality of services provided by Davis.
This evaluation included an analysis of the resources of Davis. The Board also
examined the investment performance of the fund (see discussion in Proposal 3
under "Basis for Recommendation of the Board - Investment Performance.") Based
on the foregoing, the Board determined that the nature, extent and quality of
advisory services provided by Davis were satisfactory. The Board also analyzed
the cost of services to the fund as well as to Davis. In this regard, the Board
observed that the fees earned by Davis for providing investment management
services under the proposed Davis Agreement would be the same as they are now.
The Board also considered the total expense ratio of the fund (see discussion in
Proposal 3 under "Basis for Recommendation of the Board - Cost of Services
Provided" for detail regarding these considerations). Additionally, the Board
took into account that the fee schedule in the proposed Davis Agreement includes
"breakpoints" that would be triggered as fund asset levels grow. Based on the

PROPOSAL 7: APPROVE OR REJECT CHANGES IN FUNDAMENTAL INVESTMENT POLICIES

(Applies to: ALL FUNDS)

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 (Applies to: ALL FUNDS EXCEPT CALIFORNIA TAX-EXEMPT, GLOBAL
BOND, GLOBAL TECHNOLOGY, INFLATION PROTECTED SECURITIES, MASSACHUSETTS
TAX-EXEMPT, MICHIGAN TAX-EXEMPT, MINNESOTA TAX-EXEMPT, NEW YORK TAX-EXEMPT, OHIO
TAX-EXEMPT, PORTFOLIO BUILDER AGGRESSIVE, PORTFOLIO BUILDER CONSERVATIVE,
PORTFOLIO BUILDER MODERATE FUND, PORTFOLIO BUILDER MODERATE AGGRESSIVE,
PORTFOLIO BUILDER MODERATE CONSERVATIVE, PORTFOLIO BUILDER TOTAL EQUITY,
PRECIOUS METALS, VP GLOBAL BOND)

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. For most of the funds, this will be a revision to an existing
policy. For European Equity, Real Estate, S&P 500 Index, Small Cap Value, VP S&P
500 Index and VP Small Cap Value this will be a new policy. Each of those funds
originally was established as a non-diversified fund. Recently, however, the
funds have been managed as diversified funds. Consequently, the Board recommends
that each of the funds adopt policies consistent with operation as a diversified
fund. The Board recommends that shareholders vote to replace the fund's current
fundamental investment policy with, or adopt, the following policy (additional
or revised language is [UNDERLINE]underlined[/UNDERLINE]):

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

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

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       54
<Page>

limit in the securities of other investment companies. Pursuant to an exemptive
order granted by the Securities and Exchange Commission (the "SEC"), the fund
may invest up to 25% of its total assets in a non-publicly offered money market
fund managed by RiverSource Investments (the "cash pool fund"). The cash pool
fund is not expected to pay investment advisory, management, or transfer agent
fees, although it may do so subject to the conditions of the SEC order and Board
approval. The cash pool fund will incur minimal costs for services, such as
custodian and auditor fees. The investment manager anticipates that making use
of the cash pool fund will benefit the fund by enhancing the efficiency of cash
management and by providing increased short-term investment opportunities. If
the proposal is approved, the cash pool fund is expected to serve as a principal
option for managing the cash positions of the fund. Future amendments to the
fund's fundamental diversification policy would continue to require shareholder
approval.

B.   TEN PERCENT LIMITATION IN SINGLE ISSUER (Applies to: BALANCED, CASH
     MANAGEMENT, DIVERSIFIED BOND, DIVERSIFIED EQUITY INCOME, DIVIDEND
     OPPORTUNITY, EMERGING MARKETS, EQUITY VALUE, EUROPEAN EQUITY, GLOBAL BOND,
     GLOBAL EQUITY, GROWTH, HIGH YIELD BOND, INTERMEDIATE TAX-EXEMPT,
     INTERNATIONAL OPPORTUNITY, MID CAP GROWTH, REAL ESTATE, S&P 500 INDEX,
     SELECT VALUE, SHORT DURATION U.S. GOV'T, SMALL CAP ADVANTAGE, SMALL CAP

     VP INTERNATIONAL OPPORTUNITY, VP LARGE CAP EQUITY, VP MID CAP GROWTH, VP
     S&P 500 INDEX, VP SHORT DURATION U.S. GOV'T, VP SMALL CAP VALUE)

The Board recommends that the fund's fundamental policy with respect to
investment in a single issuer be revised to permit the fund the maximum
flexibility permitted by the 1940 Act. For most of the funds, this will be a
revision to an existing policy as illustrated below. For European Equity, Real
Estate, Small Cap Value, S&P 500 Index, VP S&P 500 Index and VP Small Cap Value,
this will be a new policy. Each of those funds originally was established as a
non-diversified fund. Recently, however, the funds have been managed as
diversified funds. Consequently, the Board recommends that each of the funds
adopt policies consistent with operation as a diversified fund. The Board
recommends that shareholders vote to replace the fund's current fundamental
investment policy with, or adopt, the following policy (additional language is
[UNDERLINE]underlined[/UNDERLINE]):

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

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       55
<Page>

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

C. LENDING (Applies to: ALL FUNDS)

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 may not borrow for leverage or investment purposes.
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.

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       56
<Page>

D. BORROWING (Applies to: ALL FUNDS)

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.

E. PRECIOUS METALS (Applies to: PRECIOUS METALS)

The fund has a policy that states:

     The fund will invest at least 25% of its total assets in the precious
     metals industry, based on current market value at the time of purchase,
     unless market conditions temporarily require a defensive investment
     strategy.

The Board recommends that shareholders approve the elimination of this policy.
Under the SEC's name rule, so long as the fund has the words "Precious Metals"
in its name, it must invest at least 80% of its assets in the precious metals
industry. If the Board were to decide to change the name of the fund to
something other than Precious Metals, shareholders would receive at least 60
days notice of the change. However, if the Board were to decide to change the
name of the fund, the fundamental policy regarding investment in precious metals
could not be changed without a shareholder vote. While the Board has no current
intention of changing the name of the fund or the policy of investing in
precious metals, eliminating the fundamental policy regarding precious metals
will provide the Board with the flexibility to make changes in the future
without shareholder approval.

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.

SECTION C - PROXY VOTING AND SHAREHOLDER MEETING INFORMATION

This section includes information about proxy voting and the shareholder
meetings.

VOTING. You are entitled to vote based on your total dollar interest in a 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.

Each corporation or trust issues one or more series of shares. 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 same corporation or trust. On the
Investment Management Services Agreement, Subadvisory Agreement, and changes in
fundamental policies, 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 decide 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. If your investments include any
of the variable portfolio funds, you have the right to instruct IDS Life
Insurance Company ("IDS Life") or IDS Life Insurance Company of New York ("IDS
Life of New York") how to vote the variable portfolio fund shares held under
your annuity contract or life insurance

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       58
<Page>

policy. You do this by voting yourself. IDS Life and IDS Life of New York will
vote any fund shares for which they do not receive voting instructions in
proportionately the same manner - either For, Against or Abstain - as shares for
which they do receive instructions.

MASTER/FEEDER FUNDS. Some funds are part of a master/feeder structure. The
feeder funds seek their investment objectives by investing their assets in
master funds with the same policies. Master funds invest in and manage the
securities. Proposals 3, 5 and 7 affect certain master funds. Feeder funds, as
the sole shareholders of the master fund, will vote for or against each of those
proposals in proportion to the vote received from feeder fund shareholders.

The Board of each feeder fund has determined that it is in the best interests of
shareholders to withdraw the fund's assets from the master/feeder structure. The
necessary steps to finalize the withdrawal are expected to be completed in late
2005 or early 2006. After that date, each feeder fund will invest directly in
and manage its own portfolio of securities rather than investing in a master
portfolio. RiverSource Investments is the investment adviser to the master
portfolio and will continue to serve as the feeder fund's investment adviser
under the terms and conditions in the IMS Agreement described in Proposal 3. If
the withdrawal from the master fund is completed prior to the date of the
shareholder meeting, shareholders of the former feeder fund will vote directly
on all issues.

REVOKING YOUR PROXY. If your plans change after you vote your proxy and you
would like to vote in person at 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, you may change your vote or revoke it by mail, telephone or
internet.

JOINT PROXY STATEMENT/SIMULTANEOUS MEETINGS. This joint proxy statement reduces
the preparation, printing and mailing costs of sending separate proxy statements
for each fund. The meetings will be held simultaneously with each proposal being
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. Ameriprise Financial will pay the expenses for the
proxy material, postage and any supplementary solicitations, which may be made
by mail, telephone, electronic means or personal contact by financial advisors.

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. Any proposal that a
shareholder intends to present at a future shareholder meeting must be submitted
to the funds in writing in reasonable time prior to the solicitation of proxies
for the meeting

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 any 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 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 any of the proposals. 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.

ANNUAL REPORT. The latest annual report was previously mailed to you. If you
would like another copy of the annual report and any subsequent semi-annual
report, without charge, please write RiverSource Funds, 70100 Ameriprise
Financial Center, Minneapolis, MN 55474 or call (800) 862-7919.

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 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:

JOINT AUDIT COMMITTEE CHARTER

This charter is scheduled to be reviewed at an upcoming meeting of the Board. At
that time, the Board is expected to update the charter, including changing
references from American Express Financial Corporation and its subsidiaries to
Ameriprise Financial, Inc. and its subsidiaries. In addition, references to
American Express Company will be eliminated.

MEMBERSHIP AND QUALIFICATIONS

The Joint Audit Committee shall consist of at least three members appointed by
the Board. The Board may replace members of the Committee for any reason.

No member shall be an "interested person" as that term is defined in Section
2(a)(19) of the Investment Company Act, nor shall any member receive any
compensation from the Fund except compensations for service as a member of the
Board and Board committees.

At least one member of the Committee shall be an "audit committee financial
expert." An "audit committee financial expert" means a person who has the
following attributes:

- -  An understanding of generally accepted accounting principles and financial
   statements;

- -  The ability to assess the general application of such principles in
   connection with the accounting for estimates, accruals, and reserves;

- -  Experience preparing, auditing, analyzing, or evaluating financial statements
   that present a breadth and level of complexity of accounting issues that are
   generally comparable to the breadth and complexity of issues that can
   reasonably be expected to be raised by the registrant's financial statements,
   or experience actively supervising one or more persons engaged in such
   activities;

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

                    RIVERSOURCE FUNDS -- PROXY STATEMENT
                                       B.4
<Page>

conducting the audit and rendering their audit report, the authority to retain

deems necessary, and the authority to obtain specialized training for Committee

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 more officers
of the Fund whom the director reasonably believes to be reliable and competent
in the matters presented; (2) legal counsel, public accountants, or other
persons as to matters the director reasonably believes are within the person's
professional or expert competence; or (3) a Board committee of which the
director is not a member.

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

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

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

documentation of decisions made outside of meetings by delegated authority.

                                this signature should be that of an authorized
                                officer who should state his or her title.

                                 PROXY STATEMENT

                                                               December 16, 2005

HERE IS A BRIEF OVERVIEW OF SOME OF THE CHANGES BEING RECOMMENDED FOR YOUR
RIVERSOURCE MUTUAL FUND OR VARIABLE PORTFOLIO 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/Trustees (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 (in
most cases, 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?

At all regular meetings, shareholders elect Board members. In addition,
shareholders at this meeting will vote on other proposals. These include:

- -  Amending the Fund's Articles of Incorporation to permit the Board to
   establish the minimum account value and to change the name of the
   corporation.

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

- -  Approving a subadvisory agreement with Kenwood Capital Management LLC
   (Kenwood), Threadneedle International Limited or Davis Advisors (Davis).

- -  Approving changes in fundamental investment policies related to
   diversification, lending and borrowing.

Some of these changes affect all Funds, while others affect only certain Funds.
Please refer to "Section A - Overview" of the proxy statement to see what
proposals apply to your Fund. We encourage you to read the full text of the
proxy statement to obtain a more detailed understanding of the issues.

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. For equity and balanced funds, the new agreement also clarifies the
circumstances under which the Board may change an index for purposes of
calculating a performance incentive adjustment. For variable portfolio funds,
the agreement eliminates transfer agency services, which will be provided under
a separate agreement if shareholders approve the new agreements. Finally, for
many funds the new agreement includes revised fee schedules. The fee schedules
reflect the pricing philosophy recommended by the investment manager and
approved by the Board. Under that pricing philosophy, management fees are set so
that net expenses for most funds will be at or below median net expenses
relative to a peer group of comparable funds.

Q: WHAT CHANGES ARE PROPOSED TO THE SUBADVISORY AGREEMENTS?

Certain subadvisers are considered affiliates of RiverSource Investments.
Shareholders of funds advised by those subadvisers are being asked to approve
the subadvisory agreements as a result of the spin off described in the previous
paragraph. In addition, the subadvisory agreements with Kenwood and Davis
include proposed changes in the fee schedules. Because subadvisory fees are paid
to Kenwood and Davis by RiverSource Investments, not by the Funds, the proposed
change will not affect the expenses of the Funds or the cost to shareholders.

Q: WHAT CHANGES ARE PROPOSED TO FUND POLICIES?

Policies are being standardized to match the other funds in the group and to
eliminate unnecessary limitations. This will not change the way your Fund is
managed.

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. If you own more than one Fund, it is important that you
vote for each Fund.

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.
