Effective Sept. 7, 2010, (the Effective Date) the Columbia funds, Columbia Acorn
funds and RiverSource funds (including the Seligman and Threadneedle branded
funds) share the same policies and procedures for investor services, as
described below and in the prospectus, as supplemented. For example, for
purposes of calculating the initial sales charge on the purchase of Class A
shares of a fund, an investor or financial advisor should consider the combined
market value of all Columbia, Columbia Acorn, RiverSource, Seligman and
Threadneedle funds owned



by the investor. See Rights of Accumulation (ROA) in the prospectus, as
supplemented, for details on this particular policy.

For purposes of this Supplement, the Columbia funds and Columbia Acorn funds and
portfolios are collectively referred to as the Columbia funds. The RiverSource
funds (including the Seligman and Threadneedle branded funds) are collectively
referred to as the funds. Together the Columbia funds and the RiverSource funds
are referred to as the funds. On Sept. 27, 2010, certain of the RiverSource,
Seligman and Threadneedle funds will change their names to reflect the Columbia
brand. Regardless of the name change to a RiverSource fund, a Seligman fund or a
Threadneedle fund, each of these funds should be regarded as a RiverSource fund,
Seligman fund or Threadneedle fund (per their name as the date of this
supplement) and should not be considered a "Columbia fund" for purposes of this
Supplement.

The following terms have the following meaning: Columbia Management or the
investment manager refers to Columbia Management Investment Advisers, LLC, the
transfer agent refers to Columbia Management Investment Services Corp., and the
distributor refers to Columbia Management Investment Distributors, Inc. In
addition, as used throughout this Supplement, the terms "selling agent" and
"servicing agent" refer to the financial intermediary that employs your
financial advisor. Selling and/or servicing agents include, for example,
brokerage firms, banks, investment advisors, third party administrators and
other financial intermediaries.

On the Effective Date, certain of the fund share classes will be converted or
redesignated (renamed) and certain share classes will be closed. Each conversion
and renaming will be treated as a non-reportable, non-taxable transaction. The
current share classes offered by the funds and their status as of the Effective
Date (or other date, as noted below) are as follows:



CURRENT SHARE CLASS
(PRIOR TO THE EFFECTIVE DATE)            SHARE CLASS ON AND AFTER THE EFFECTIVE DATE

Class Z                         Class Z


- ----------
(a)  Relates to RiverSource S&P 500 Index Fund.

(b)  Class R3, Class R4 and Class R5 shares are closed to new investors as of
     the close of business on Dec. 31, 2010.

(c)  For RiverSource Cash Management Fund, Class Y will be converted to Class Z
     shares on or about August 27, 2010. For the RiverSource Retirement Plus
     funds, Class Y shares will be renamed as Class Z shares on the Effective
     Date.

Accordingly, on the Effective Date, the funds will offer the following share
classes: Class A, Class C, Class I, Class R, Class W and Class Z shares, and
will offer Class R3, Class R4 and Class R5 until their close effective at the
close of business on Dec. 31, 2010.



ON THE EFFECTIVE DATE, THE SAI IS REVISED AS FOLLOWS:

The "Sales Charge" section of Investing in a Fund is superseded and replaced
with the following:

SALES CHARGE

Investors should understand that the purpose and function of the initial sales
charge and distribution fee for Class A shares is the same as the purpose and
function of the contingent deferred sales charge ("CDSC") and distribution fee
for Class B and Class C shares. The sales charges and distribution fees
applicable to each class pay for the distribution of shares of a fund.

Shares of a fund are sold at the class' public offering price. For funds other
than money market funds and, as noted below in Table 9, certain other funds, the
public offering price for Class A shares is the NAV of one share adjusted for
the sales charge applicable to the class. For money market funds and, as noted
below in Table 9, certain other funds, the public offering price is the NAV. For
all funds, for Class B, Class C, Class I, Class R, Class R3, Class R4, Class R5,
Class W and Class Z there is no initial sales charge so the public offering
price is the same as the NAV.

CLASS A - CALCULATION OF THE SALES CHARGE

Sales charges are determined as shown in the following tables. The first table
is organized by investment category. You can find your fund's investment
category in Table 1.

                      TABLE 9. CLASS A INITIAL SALES CHARGE

*    RiverSource S&P 500 Index Fund is not subject to a front-end sales change
     on Class A shares.

(a)  Because the offering price is calculated to two decimal places, the dollar
     amount of the sales charge as a percentage of the offering price and your
     net amount invested for any particular purchase of fund shares may be
     higher or lower depending on whether downward or upward rounding was
     required during the calculation process.

(b)  Purchase price includes the sales charge.



(c)  Although there is no sales charge for purchases with a total market value
     of $1 million or more, and therefore no re-allowance, the distributor may
     pay a selling and/or servicing agent the following out of its own
     resources: 1.00% on purchases from $1 million up to but not including $3
     million; 0.50% on purchases of $3 million up to but not including $50
     million; and 0.25% on amounts of $50 million or more. The distributor may
     be reimbursed if a CDSC is deducted when the shares are redeemed.

(d)  For eligible employee benefit plans, selling and/or servicing agents are
     eligible to receive from the distributor the following sales commissions on
     purchases that are coded as commission eligible trades: 1.00% on all
     purchases up to but not including $3 million, including those in amounts of
     less than $1 million; up to 0.50% on all purchases of $3 million up to but
     not including $50 million; and up to 0.25% on all purchases of $50 million
     or more.

The information under the following subsections that appear after "Table 10.
Public Offering Price" is superseded and replaced with the following:

CLASS A--STATEMENT OR LETTER OF INTENT (LOI)

If you intend to invest $50,000 or more over a period of time, you may be able
to reduce the sales charge you pay on investments in Class A, Class E or Class T
shares by completing a LOI form and committing to invest a certain amount. The
LOI must be filed with and accepted in good order by the distributor of the
funds. You will have up to 13 months from the date of your LOI to fulfill your
commitment. Existing Rights of Accumulation (ROA) can be included for purposes
of meeting your commitment under the LOI. For example, a shareholder currently
has $60,000 ROA in the funds. Shareholder completes an LOI to invest $100,000 in
the funds (ROA eligible accounts). Shareholder only needs to invest an
additional $40,000 in the funds' Class A shares over the next 13 months in order
to fulfill the LOI commitment, during which time the shareholder receives
reduced front-end sales charge(s) on investments. Your investments during this
13-month period will be charged the sales charge that applies to the amount you
have committed to invest under the LOI. A portion of your commitment will be
invested in Class A, Class E or Class T shares, as the case may be, and placed
in escrow. At the end of the 13-month period, the LOI will end and the shares
will be released from escrow (less any amount necessary to pay sales charges to
the extent the LOI commitment was not met, as described below). Once the LOI has
ended or your investments entitle you to a lower sale charge than would
otherwise be available to you under the LOI, future sales charges will be
determined by Rights of Accumulation (ROA) as described in the prospectus. If
you do not invest the commitment amount by the end of the 13-month period, the
remaining unpaid sales charge will be redeemed from the escrowed shares and the
remaining balance released from escrow. For purposes of making an LOI to
purchase additional shares, you may aggregate your ownership of different
classes of shares, except Class I, Class R, Class R3, Class R4, Class R5 and
Class Y shares. For example, if your LOI commits you to purchases Class A
shares, the commitment amount does not include purchases in these classes of
shares; does not include any new reinvested dividends and directed dividends
earned in any funds during the 13-month period; and purchases of money market
funds unless they are subsequently exchanged for shares of a non-money market
fund (other than Class I, Class R, Class R3, Class R4, Class R5 and Class Y
shares of such non-money market fund) within the 13-month period. A LOI is not
an option (absolute right) to buy shares. If you purchase shares through
different channels, for example, in a brokerage account or through a third
party, you must inform your financial intermediary in writing about the LOI when
placing any purchase orders during the period of the LOI. 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.

CLASS A SHARES

Class A shares may be sold at net asset value to certain persons since such
sales require less sales effort and lower sales-related expenses as compared
with sales to the general public. If you are eligible to purchase Class A shares
without a sales charge, you should inform your financial advisor, selling and/or
servicing agent or the fund's transfer agent of such eligibility and be prepared
to provide proof thereof. For Class A shares purchased without a sales charge
where a commission was separately paid by the distributor to a selling and/or
servicing agent effecting the purchase, a CDSC may be charged if you sell your
shares within, except as provided below, 18 months after purchase, charged as
follows: a 1.00% CDSC if redeemed within 12 months of purchase, and 0.50% CDSC
if redeemed more than 12, but less than 18, months after purchase. A CDSC is
based on the original purchase cost or the current market value of the shares
being sold, whichever is less.

INITIAL SALES CHARGE --WAIVERS OF THE SALES CHARGE FOR CLASS A SHARES. Sales
charges do not apply to:

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

     -    participants of "eligible employee benefit plans" including 403(b)
          plans for which Ameriprise Financial Services, Inc. (Ameriprise

          or group received a written proposal from Ameriprise Financial
          Services between November 1, 2007 and Dec. 31,



          2008 (each a Qualifying 403(b) Plan). In order for participants in one
          of these 403(b) plans to receive this waiver, at least one participant
          account of the 403(b) plan must have been funded at Ameriprise
          Financial Services prior to Dec. 31, 2009. This waiver may be
          discontinued for any Qualifying 403(b) Plan, in the sole discretion of
          the distributor, after Dec. 31, 2009.

     -    to separate accounts established and maintained by an insurance
          company which are exempt from registration under Section 3(c)(11) of
          the 1940 Act.

          participate in Seligman Growth 401(k) through Ascensus's (formerly
          BISYS) third party administration platform may, with new
          contributions, purchase Class A shares at net asset value. Class A
          shares purchased at net asset value on or prior to Sept. 3, 2010 are
          subject to a CDSC on shares purchased within 18 months prior to plan
          termination, charged as follows: 1.00% CDSC if redeemed within 12
          months of purchase, and 0.50% CDSC if redeemed more than 12, but less
          than 18, months after purchase.

     -    to participants in retirement and deferred compensation plans and
          trusts used to fund those plans, including but not limited to, those
          defined in Sections 401(a), 401(k), 403(b) or 457 of the Internal
          Revenue Code and "rabbi trusts" for which Charles Schwab & Co., Inc.
          acts as broker dealer.

     -    to participants in plans established at the transfer agent (Seligman
          funds only) prior to January 7, 2008, the plan had $500,000 or 50
          participants when the shares were initially purchased.

     -    to participants in retirement and benefit plans made through financial
          intermediaries that perform participant recordkeeping or other
          administrative services for the plans and that have entered into
          special arrangements as alliance program partners with the funds
          and/or the distributor specifically for such purchases.

     -    to other funds pursuant to a "fund-of-funds" arrangement provided that
          the fund is distributed by the distributor.

CDSC--WAIVERS OF THE CDSC FOR CLASS A CLASS C, CLASS E, AND CLASS T SHARES. The
CDSC will be waived on sales of Class A, Class C, Class E, and Class T shares:

     -    in connection with participation in the Merrill Lynch Small Market
          401(k) Program, retirement programs administered or serviced by the
          Princeton Retirement Group, Paychex, ADP Retirement Services, Hartford
          Securities Distribution Company, Inc. or NYLIM Service Company LLC,
          retirement programs or accounts administered or serviced by Mercer HR
          Services, LLC or its affiliates, or retirement programs or accounts
          administered or serviced by firms that have a written agreement with
          the distributor that contemplates a waiver of CDSCs, provided that no
          sales commission or transaction fee was paid to such authorized
          financial institution at the time of purchase.

The CDSC will be waived on sales of Class A, Class B and Class C shares of a
Columbia fund purchased prior to September 7, 2010:

     -    after the sole shareholder on an individual account or a joint tenant
          on a joint tenant account becomes disabled (as defined by Section
          72(m)(7) of the Internal Revenue Code). To be eligible for such a
          waiver: (i) the disability must arise after the account is opened and
          (ii) a letter from a physician must be signed under penalty of perjury
          stating the nature of the disability. If the account is transferred to
          a new registration and then shares are sold, the applicable CDSC will
          be charged.*

     -    by health savings accounts sponsored by third party platforms,
          including those sponsored by affiliates of Bank of America.*

     -    for the following purposes (i) to make medical payments that exceed
          7.5% of income and (ii) to pay for insurance by an individual who has
          separated from employment and who has received unemployment
          compensation under a federal or state program for at least twelve
          weeks.*

     -    pursuant to the Fund's Systematic Withdrawal Plan established with the
          Transfer Agent, to the extent that the sales do not exceed, on an
          annual basis, 12% of the account's value as long as distributions are
          reinvested. Otherwise, a CDSC will be charged on sales through the
          Fund's Systematic Withdrawal Plan until this requirement is met.



     -    in connection with distributions from qualified retirement plans,
          government (Section 457) plans, individual retirement accounts or
          custodial accounts under Section 403(b)(7) of the Internal Revenue
          Code following normal retirement or the attainment of age 59 1/2.**

     -    in connection with loans from qualified retirement plans to
          shareholders.*

     -    Any shareholder who owned shares of any fund of Columbia Acorn Trust
          (formerly named Liberty Acorn Trust) on September 29, 2000 (when all
          of the then outstanding shares of Columbia Acorn Trust were
          re-designated Class Z shares) and who since that time remained a
          shareholder of any Fund, may buy Class A shares of any Fund without
          paying a front-end sales charge in those cases when Class Z shares is

CLASS B SHARES -- CLOSED

EFFECTIVE AFTER THE CLOSE OF BUSINESS ON THE EFFECTIVE DATE, THE FUNDS NO LONGER
ACCEPT INVESTMENTS FROM NEW OR EXISTING INVESTORS IN CLASS B SHARES, EXCEPT FOR
CERTAIN LIMITED TRANSACTIONS INVOLVING EXISTING INVESTORS IN CLASS B SHARES,
EXCEPT FOR CERTAIN LIMITED TRANSACTIONS INVOLVING EXISTING INVESTORS IN CLASS B
SHARES AS DESCRIBED IN MORE DETAIL IN THE FUND'S PROSPECTUS, AS SUPPLEMENTS.

Class B shares have a CDSC. For purposes of calculating the CDSC on shares of a
RiverSource fund purchased after the close of business on Sept. 3, 2010, the
start of the holding period is the first day of the month in which your purchase
was made. For purposes of calculating the CDSC on shares of a RiverSource fund
purchased on or before the close of business on Sept. 3, 2010, the start of the
holding period is the date your purchase was made. When you place an order to
sell your Class B shares, the fund will first redeem any shares that aren't
subject to a CDSC, followed by those you have held the longest. This means that
if a CDSC is imposed, you cannot designate the individual shares being redeemed
for federal income tax purposes. You should consult your tax advisor about the
tax consequences of investing in the funds.

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

     -    in connection with participation in the Merrill Lynch Small Market
          401(k) Program, retirement programs administered or serviced by the
          Princeton Retirement Group, Paychex, ADP Retirement Services, Hartford
          Securities Distribution Company, Inc. or NYLIM Service Company LLC,
          retirement programs or accounts administered or serviced by Mercer HR
          Services, LLC or its affiliates, or retirement programs or accounts
          administered or serviced by firms that have a written agreement with
          the distributor that contemplates a waiver of CDSCs, provided that no
          sales commission or transaction fee was paid to such authorized
          financial institution at the time of purchase.

     -    of RiverSource funds held in investment-only accounts (i.e. accounts
          where Ameriprise Trust Company does not act as the custodian) at
          Ameriprise Financial Services on behalf of a trust for an employee
          benefit plan.

     -    of RiverSource funds held in IRAs or certain qualified plans, on or
          prior to June 12, 2009, such as Keogh plans, tax-sheltered custodial
          accounts or corporate pension plans where Ameriprise Trust Company is
          acting as custodian, 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.

     -    of sales of Class B shares for RiverSource funds purchased prior to
          Sept. 7, 2010 sold under an approved substantially equal periodic
          payment arrangement (applies to retirement accounts when a shareholder
          sets up an arrangement with the Internal Revenue Service).**

*    You must notify the fund or the transfer agent prior to redeeming shares of
     the applicability of the CDSC waiver, but final decision of the
     applicability of the CDSC waiver is contingent on approval of the fund or
     the transfer agent.

**   Fund investors and selling and/or servicing agents must inform the fund or
     the transfer agent in writing that the fund investor qualifies for the
     particular sales charge waiver and provide proof thereof.

The Transfer Agency Services and Plan Administration Services sections are
superseded and replaced with the following:

TRANSFER AGENCY SERVICES

The funds have a Transfer Agency Agreement with Columbia Management Investment
Services Corp. (the "transfer agent") (formerly RiverSource Service Corporation)
located at One Financial Center, Boston, MA 02111. This agreement governs the
transfer agent's responsibility for administering and/or performing transfer
agent functions, for acting as service agent in connection with dividend and
distribution functions and for performing shareholder account administration
agent functions in connection with the issuance, exchange and redemption or
repurchase of the fund's shares.

For Class A, Class B, Class C, Class R, Class R3, Class R4, Class R5, Class W,
Class Y and Class Z, the transfer agent will earn an open account fee determined
by multiplying the number of open accounts by the annual rate of $12.08. The
annual per account fee is accrued daily and payable monthly. The fund will
allocate the fee daily across their share classes based on the relative
percentage of net assets of each class of shares.

In addition, for Class A, Class B, Class C, Class R, Class W and Class Z, the
fund reimburses the transfer agent for the fees and expenses the transfer agent
pays to financial intermediaries that maintain omnibus accounts with the fund
subject to an annual limitation of 0.20% of the average aggregate value of the
fund's shares maintained in each such omnibus account (other than omnibus
accounts for which American Enterprise Investment Services, Inc. is the broker
of record or accounts where the beneficial shareholder is a customer of
Ameriprise Financial Services, Inc., which are reimbursed in an amount equal to
$16.00 annually, calculated monthly based on the total number of positions in
such account at the end of such month). For Class R3, Class R4 and Class R5, the
fees paid to the transfer agent for expenses paid to financial intermediaries to
maintain omnibus accounts are subject to an annual limitation of 0.05% of the
net assets attributable to such shares. Class I does not pay transfer agency
fees.

The fund also pays certain reimbursable out-of-pocket expenses to the transfer
agent. The transfer agent also may retain as additional compensation for its
services revenues for fees for wire, telephone and redemption orders, IRA



trustee agent fees and account transcripts due the transfer agent from fund
shareholders and credits (net of bank charges) earned with respect to balances
in accounts the transfer agent maintains in connection with its services to the
funds. The fees paid to the transfer agent may be changed by the Board without
shareholder approval.

PLAN ADMINISTRATION SERVICES

The funds that offer Class R3 and Class R4 shares have a Plan Administration
Services Agreement with the transfer agent. Under the agreement the fund pays
for plan administration services, including services such as implementation and
conversion services, account set-up and maintenance, reconciliation and account
recordkeeping, education services and administration to various plan types,
including 529 plans, retirement plans and Health Savings Accounts (HSAs).

The fee for services is equal on an annual basis to 0.25% of the average daily
net assets of the fund attributable to each of Class R3 and R4.

The fees paid to the transfer agent may be changed by the Board without
shareholder approval.

The information under the section Plan and Agreement of Distribution is
superseded and replaced with the following:

PLAN AND AGREEMENT OF DISTRIBUTION

To help defray the cost of distribution and/or servicing not covered by the
sales charges received under the Distribution Agreement, the funds approved a
Plan of Distribution (the "Plan") and entered into an agreement under the Plan
pursuant to Rule 12b-1 under the 1940 Act. The Plan is a reimbursement plan
whereby the fund pays the distributor a fee up to actual expenses incurred.

The table below shows the maximum annual distribution and/or service fees (as an
annual percent of average daily net assets) and the combined amount of such fees
(as an annual percent of average daily net assets) applicable to each share
class:



SHARE CLASS   DISTRIBUTION FEE   SERVICE FEE   COMBINED TOTAL
- -----------   ----------------   -----------   --------------
                                      
Class A       up to 0.25%        up to 0.25%   0.25%(a)
Class B       0.75%              0.25%         1.00%(b)
Class C       0.75%              0.25%         1.00%(a)
Class I       None               None          None
Class R       up to 0.50%        up to 0.25%   0.50%(a), (c)
Class R3      0.25%              0.25%(d)      0.50%(d)
Class R4      none               0.25%(d)      0.25%(d)
Class R5      None               None          None
Class W       up to 0.25%        up to 0.25%   0.25%(a)
Class Z       None               None          None


(a)  Fee amounts noted apply to all funds other than RiverSource Cash Management
     Fund, which, for each of Class A and Class W shares, pays distribution and
     service fees of 0.10%, and for Class C shares pays distribution fees of
     0.75%. The distributor has voluntarily agreed, effective April 15, 2010, to
     waive the 12b-1 fees it receives from Class A, Class C, Class R (formerly
     Class R2) and Class W shares of RiverSource Cash Management Fund and from
     Class A, Class C and Class R (formerly Class R2) shares of RiverSource
     Government Money Market Fund. Compensation paid to broker-dealers and other
     financial intermediaries may be suspended to the extent of the
     distributor's waiver of the 12b-1 fees on these specific share classes of
     these funds.

(b)  Fee amounts noted apply to all funds other than RiverSource Cash Management
     Fund, which pays distribution fees of up to 0.75% and service fees of up to
     0.10% for a combined total of 0.85%. Effective after the close of business
     on Sept. 3, 2010, Class B shares will be closed to new and existing
     investors.

(c)  The funds have a distribution and shareholder service plan for Class R
     shares, which, prior to the close of business on Sept. 3, 2010, were known
     as Class R2 shares. For Class R shares, the maximum fee under the plan
     reimbursed for distribution expenses is equal on an annual basis to 0.50%
     of the average daily net assets of the fund attributable to Class R shares.
     Of that amount, up to 0.25% may be reimbursed for shareholder service
     expenses.

(d)  The shareholder service fees for Class R3 and Class R4 shares are not paid
     pursuant to a 12b-1 plan. Under a Plan Administration Services Agreement,
     the funds' Class R3 and Class R4 shares pay for plan administration
     services, including services such as implementation and conversion
     services, account set-up and maintenance, reconciliation and account
     recordkeeping, education services and administration to various plan types,
     including 529 plans, retirement plans and health savings accounts.


The distribution and/or shareholder service fees for Class A, Class B, Class C,
Class R (formerly Class R2), Class R3 and Class W shares, as applicable, are
subject to the requirements of Rule 12b-1 under the 1940 Act, and are to
reimburse the distributor for certain expenses it incurs in connection with
distributing the fund's shares and directly or indirectly providing services to
fund shareholders. These payments or expenses include providing distribution
and/or shareholder service fees to selling and/or servicing agents that sell
shares of the fund or provide services to fund shareholders. The distributor may
retain these fees otherwise payable to selling and/or servicing agents if the
amounts due are below an amount determined by the distributor in its discretion.

For Class A, Class B and Class W shares, the distributor begins to pay these
fees immediately after purchase. For Class C shares, the distributor pays these
fees in advance for the first 12 months. Selling and/or servicing agents also
receive distribution fees up to 0.75% of the average daily net assets of Class C
shares sold and held through them, which the distributor begins to pay 12 months
after purchase. For Class B shares, and, for the first 12 months following the
sale of Class C shares, the distributor retains the distribution fee of up to
0.75% in order to finance the payment of sales commissions to selling and/or
servicing agents, and to pay for other distribution related expenses. Selling
and/or servicing agents may compensate their financial advisors with the
shareholder service and distribution fees paid to them by the Distributor.

IF YOU MAINTAIN SHARES OF THE FUND DIRECTLY WITH THE FUND, WITHOUT WORKING
DIRECTLY WITH A FINANCIAL ADVISOR OR SELLING AND/OR SERVICING AGENT,
DISTRIBUTION AND SERVICE FEES ARE RETAINED BY THE DISTRIBUTOR AS PAYMENT OR
REIMBURSEMENT FOR INCURRING CERTAIN DISTRIBUTION AND SHAREHOLDER SERVICE RELATED
EXPENSES.

Over time, these distribution and/or shareholder service fees will reduce the
return on your investment and may cost you more than paying other types of sales
charges. The fund will pay these fees to the distributor and/or to eligible
selling and/or servicing agents for as long as the distribution and/or
shareholder servicing plans continue in effect. The fund may reduce or
discontinue payments at any time. Your selling and/or servicing agent may also
charge you other additional fees for providing services to your account, which
may be different from those described here.

Appendix D is superseded and replaced with the following:

CLASS A - CALCULATION OF THE SALES CHARGE

*    RiverSource S&P 500 Index Fund is not subject to a front-end sales change
     on Class A shares.

(a)  Because the offering price is calculated to two decimal places, the dollar
     amount of the sales charge as a percentage of the offering price and your
     net amount invested for any particular purchase of fund shares may be
     higher or lower depending on whether downward or upward rounding was
     required during the calculation process.

(b)  Purchase price includes the sales charge.

(c)  Although there is no sales charge for purchases with a total market value
     of $1 million or more, and therefore no re-allowance, the distributor may
     pay a selling and/or servicing agent the following out of its own
     resources: 1.00% on purchases from $1 million up to but not including $3
     million; 0.50% on purchases of $3 million up to but not including $50
     million; and 0.25% on amounts of $50 million or more. The distributor may
     be reimbursed if a CDSC is deducted when the shares are redeemed.

(d)  For eligible employee benefit plans, selling and/or servicing agents are
     eligible to receive from the distributor the following sales commissions on
     purchases that are coded as commission eligible trades: 1.00% on all
     purchases up to but not including $3 million, including those in amounts of
     less than $1 million; up to 0.50% on all purchases of $3 million up to but
     not including $50 million; and up to 0.25% on all purchases of $50 million
     or more.
