                      PROSPECTUS SUPPLEMENT -- AUG. 3, 2009

RIVERSOURCE CASH MANAGEMENT FUND -- PROSPECTUS (SEPT. 29, 2008)     S-6320-99 AF

THE FRONT COVER OF THE PROSPECTUS IS REVISED TO INCLUDE THE FOLLOWING ADDITIONAL
CLASS OF SHARES: R2

The information below supplements the relevant sections of the prospectus. The
caption headings used in this Supplement correspond to the caption headings used
in the prospectus. You may purchase these shares only if you are an eligible
investor, as described under the caption "Buying and Selling Shares" below.

PAST PERFORMANCE

Class R2 is new and therefore performance information is not shown. Please note
that you will find performance returns for other classes of shares of the Fund,
together with returns of one or more broad measures of market performance, in
the performance table of the prospectus. The performance table is intended to
indicate some of the risks of investing in the Fund by showing changes in the
Fund's performance over time.

Past performance for Class R2 for the period prior to the beginning of
operations for that class may be calculated based on the performance of Class B.
The blended class performance will be adjusted to reflect differences in sales
charges, but not differences in annual Fund operating expenses (for example,
12b-1 fees). The use of blended performance generally results in a presentation
of higher performance for classes with higher operating expenses than those of
the class with which they are blended, and a presentation of lower performance
for classes with lower operating expenses than those of the class with which
they are blended.

FEES AND EXPENSES

Fund investors pay various expenses. The table below describes the fees and
expenses that you may pay if you buy and hold shares of the Fund.

The table is supplemented to include the following:

BUYING AND SELLING SHARES

The description of Investment Options is supplemented as follows:

If you are an eligible investor, you may purchase Class R2 shares at net asset
value. This share class does not have an initial sales charge or CDSC on
redemption and does not convert to any other class of shares. Class R2 shares
pay an annual distribution and shareholder servicing (12b-1) fee. Because this
fee is paid out of the Fund's assets on an ongoing basis, over time the fee will
increase the cost of your investment and may cost you more than paying other
types of distribution (sales) or servicing charges. Investments in Class R2 are
not eligible to be included in determining the sales charge for purchases of
Class A shares.

ELIGIBLE INVESTORS
The following eligible institutional investors may purchase Class R2 shares:

- Qualified employee benefit plans.

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

- Non-qualified deferred compensation plans whose participants are included in a
  qualified employee benefit plan described above.

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

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

Class R2 shares generally are not available to retail non-retirement accounts,
traditional and Roth IRAs, Coverdell Educational Savings Accounts, SEPs,
SARSEPs, SIMPLE IRAs and individual 403(b) plans.

Class R2 shares may be purchased, sold or exchanged only through the distributor
or an authorized financial intermediary.

In addition, for Class R2 shares, the distributor, in its sole discretion, may
accept or authorize financial intermediaries to accept investments from other
purchasers not listed above.

The distribution and shareholder servicing fees for Class R2 are subject to the
requirements of Rule 12b-1 under the Investment Company Act of 1940, as amended,
and are used to reimburse the distributor for certain expenses it incurs in
connection with distributing the Fund's shares and directly or indirectly
providing services to Fund shareholders. These expenses include payment of
distribution and/or shareholder servicing fees to financial intermediaries that
sell shares of the Fund or provide services to Fund shareholders, up to 0.50%*
of the average daily net assets of Class R2 shares sold and held through them.
The distributor begins to pay these fees immediately after purchase. Financial
intermediaries may compensate their financial advisors with the shareholder
servicing and distribution fees paid to them by the distributor.

In addition, Class R2 shares pay an annual plan administration services fee for
the provision of various administrative, recordkeeping, communication and
educational services. The fee for Class R2 is equal on an annual basis to 0.25%
of average daily net assets attributable to the class.

*   The distributor has currently agreed not to be reimbursed by the Fund for
    distribution (12b-1) fees equal to 0.25% of the stated amount for Class R2
    shares.

The discussion of Opening an Account is supplemented as follows:

You may purchase, sell or exchange Class R2 shares only through the distributor
or an authorized financial intermediary. Generally you may exchange your Class
R2 shares only for shares of the same class of another fund. Your exchange will
be priced at the next NAV calculated after your transaction request is received
in good order.
