SL-9942-1 A (7/09)

SUPPLEMENT, DATED MAY 1, 2009
TO THE PROSPECTUSES, EACH DATED MAY 1, 2009, FOR
SELIGMAN CASH MANAGEMENT FUND, INC.
(THE "FUND")

Capitalized terms used but not defined in this Supplement shall have the
meanings given to such terms in the Fund's Prospectuses.

On October 6, 2008, the Fund applied to participate in the initial term of the
U.S. Department of Treasury's Temporary Guarantee Program for Money Market Funds
(the "Program"), through December 18, 2008 (the "Initial Term"), after obtaining
the approval of the Board of Directors (the "Board"), including a majority of
the independent directors. On December 2, 2008, the Board approved the Fund's
participation in an extension of the Program through April 30, 2009 (the "First
Extended Term"). On April 8, 2009, the Board approved the Fund's participation
in an extension of the Program through September 18, 2009 (the "Second Extended
Term"). The Fund filed an extension notice with the U.S. Department of Treasury
on April 13, 2009 to participate in the Second Extended Term of the Program.

The Program covers shareholders of each participating money market fund for
amounts they held in such funds as of the close of business on September 19,
2008. Any increase in the number of shares of that fund held by a shareholder
after the close of business on September 19, 2008 will not be guaranteed. Any
purchase of shares of a participating money market fund after the close of
business on September 19, 2008 will not be guaranteed. If shares of a
participating fund held by a shareholder as of the close of business on
September 19, 2008 are sold before the guarantee is called upon, then the
guarantee will only cover the lesser of (i) the number of fund shares held by
the shareholder as of the close of business on September 19, 2008, or (ii) the
number of fund shares held by the shareholder on the date the guarantee is
called upon. A participating fund shareholder who sells all of his or her shares
after September 19, 2008 (and before the guarantee is called upon) will no
longer be covered by the guarantee, even if the shareholder subsequently
reinvests in the fund or in another fund that is participating in the Program.

Under the terms of the Program, the guarantee is called upon with respect to the
Fund if the Board makes a determination to liquidate the Fund. For shares
covered by the guarantee, any difference between the amount a shareholder
received in connection with the liquidation and $1.00 per share (a guarantee
payment) will be covered by the U.S. Department of Treasury under the Program,
subject to the overall amount available to all funds participating in the
Program. Guarantee payments under the Program will not exceed the amount
available in the Program (at inception of the Program, approximately $50 billion
was available to support guarantee payments).

The cost to participate in the Second Extended Term of the Program from May 1,
2009 through September 18, 2009 requires a payment to the U.S. Department of
Treasury in the amount of 0.015% of the Fund as of the close of business on
September 19, 2008. The cost to participate in the Second Extended Term will
initially be borne by the Fund without regard to any contractual expense
limitation currently in effect between the investment manager and its affiliates
and the Fund. However, to the extent the investment manager voluntarily limits
the expenses of a Fund for the purposes of supporting its yield, the cost to
participate in the Second Extended Term may be absorbed by the investment
manager. The payment to participate in the Second Extended Term of the Program
is in addition to payments to the U.S. Department of Treasury to participate in
the Initial Term and the First Extended Term of the Program. The Program will
expire after the close of business on September 18, 2009.

For additional information on the Program, visit the U.S Treasury Department's
website at www.ustreas.gov.

Effective November 7, 2008, RiverSource Investments, LLC ("RiverSource
Investments"), investment manager to the RiverSource Family of Funds, and a
wholly owned subsidiary of Ameriprise Financial, Inc. ("Ameriprise Financial"),
completed its acquisition (the "Acquisition") of J. & W. Seligman & Co.
Incorporated ("Seligman"). With the Acquisition completed and shareholders of
the Fund having previously approved (at a special meeting held on November 3,
2008) a new investment management services agreement between RiverSource
Investments and the Fund, RiverSource Investments is the new investment manager
of the Fund effective November 7, 2008.

RIVERSOURCE FAMILY OF FUNDS

The RiverSource Family of Funds includes a comprehensive array of funds from
RiverSource Investments, including the Seligman funds. RiverSource Investments
has also partnered with a number of professional investment managers, including
its affiliate, Threadneedle Investments, to expand the array of funds offered in
the RiverSource Family of Funds. The Seligman funds share the same Board of
Directors/Trustees as the other funds in the RiverSource Family of Funds.
Effective on or about June 13, 2009, the Seligman funds will share the same
policies and procedures as, and may be exchanged for shares of, the RiverSource
funds, RiverSource Partners funds and Threadneedle funds. For example, for
purposes of calculating the initial sales charge on the purchase of Class A
shares of a Seligman fund, for rights of accumulation purposes, an investor or
financial advisor MAY include the market value of any RiverSource funds,
RiverSource Partners funds or Threadneedle funds in this calculation. Please see
the Statement of Additional Information (SAI) for a complete list of mutual
funds included in the RiverSource Family of Funds.

The Fund

INVESTMENT OBJECTIVES

The Fund's investment objectives are to preserve capital and to maximize
liquidity and current income.

PRINCIPAL INVESTMENT STRATEGIES

The Fund uses the following principal investment strategies to seek its
investment objectives: The Fund invests in US dollar-denominated high-quality
money market instruments. Such instruments include obligations of the US
Treasury, its agencies or instrumentalities, obligations of domestic and foreign
banks (such as certificates of deposit and fixed time deposits), commercial
paper, short-term corporate debt securities, and repurchase agreements with
respect to these types of instruments.

The Fund will invest only in US dollar-denominated securities having a remaining
maturity of 13 months (397 days) or less and will maintain a US dollar-weighted
average portfolio maturity of 90 days or less.

In seeking to maintain a constant net asset value of $1.00, the Fund will limit
its investments to securities that, in accordance with guidelines approved by
the Fund's Board of Directors, present minimal credit risk. Accordingly, the
Fund will only purchase US government securities, or securities rated in one of
the two highest rating categories assigned to short-term debt securities by at
least two nationally recognized statistical rating organizations (such as
Moody's Investors Service ("Moody's") or Standard & Poor's Ratings Services
("S&P")), or if not so rated, determined to be of comparable quality.

Determination of quality is made at the time of investment, in accordance with
procedures approved by the Fund's Board of Directors. The investment manager
continuously monitors the quality of the Fund's investments. If the quality of
an investment declines, the Fund may, in certain limited circumstances, continue
to hold it.

Currently, the Fund invests only in US government securities and in securities
that are rated in the top category by Moody's and S&P. However, the Fund is
permitted to invest up to 5% of its assets in securities rated in the second
rating category by two rating organizations. The Fund may not invest more than
the greater of 1% of its total assets or $1,000,000 in any one security in the
second rating category.

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

Considering opportunities and risks given current interest rates and
anticipated interest rates.

Purchasing securities based on the timing of cash flows in and out of the
Fund.

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

The issuer's credit rating declines or the investment manager expects a
decline (the Fund, in certain cases, may continue to own securities that
are down-graded until the investment manager believes it is advantageous to
sell).

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

The investment manager identifies a more attractive opportunity.

The issuer or the security continues to meet the other standards described
above.

The Fund may invest in futures contracts. The Fund intends to comply with
Rule 4.5 of the Commodity Futures Trading Commission (CFTC), under which a

mutual fund is exempt from the definition of a "commodity pool operator." The
Fund, therefore, is not subject to registration or regulation as a pool
operator, meaning that the Fund may invest in futures contracts without
registering with the CFTC.

The Fund's investment objectives may be changed only with shareholder approval.
The principal investment strategies may be changed without shareholder approval.
Any material changes to these strategies, however, must be approved by the
Fund's Board of Directors.

There is no guarantee that the Fund will achieve its objectives.

PRINCIPAL RISKS

An investment in the Fund is not a deposit in a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the Fund seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Fund.

The Fund is actively managed and its performance therefore will reflect in part
the ability of the portfolio manager to select securities and to make investment
decisions that are suited to achieving the Fund's investment objectives. Due to
its active management, the Fund could underperform other mutual funds with
similar investment objectives.

Yield and total return of the Fund will fluctuate with fluctuations in the
yields of the securities held by the Fund. In periods of declining interest
rates, the yields of the securities held by the Fund will tend to be somewhat
higher than prevailing market rates, and in periods of rising interest rates,
the yields of securities held by the Fund will tend to be lower than market
rates. Additionally, when interest rates are falling, the inflow of new money to
the Fund from sales of its shares will likely be invested in securities
producing lower yields than the balance of the Fund's assets, reducing the
current yield of the Fund. In periods of rising interest rates, the opposite may
be true.

Repurchase agreements in which the Fund may invest could involve certain risks
in the event of default by the seller, including possible delays and expenses in
liquidating the securities underlying the agreement, decline in the value of the
underlying securities and loss of interest.

Investments in foreign banks and foreign branches of US banks involve certain
risks not generally associated with investments in US banks. While US banks and
US branches of foreign banks are required to maintain certain reserves and are
subject to other regulations, these requirements and regulations may not apply
to foreign banks or foreign branches of US banks. Investments in foreign banks
or foreign branches may also be subject to other risks, including political or
economic developments, the seizure or nationalization of foreign deposits and
the establishments of exchange controls or other restrictions.

Derivative instruments such as futures contracts in the Fund's portfolio involve
higher risk and may subject the Fund to higher price volatility. Derivative
instruments can present investment risk to the Fund if the investment manager
does not accurately predict the fluctuations in interest rates, currency values
or the market to which the financial instrument is tied.

PORTFOLIO HOLDINGS

A description of the Fund's policies and procedures with respect to the
disclosure of the Fund's portfolio securities is available in the Fund's
Statement of Additional Information.

PAST PERFORMANCE

Effective on or about June 13, 2009, the Fund's Class R shares are renamed as
Class R2 shares. The performance information on the following page provides some
indication of the risks of investing in the Fund by showing how the performance
of Class A shares has varied from year to year.

The following performance information is designed to assist you in comparing the
returns of the Fund with the returns of other mutual funds. How the Fund has
performed in the past, however, is not necessarily an indication of how the Fund
will perform in the future. Total returns will vary between each Class of shares
due to differing fees and expenses.

The Class A annual total returns presented in the bar chart on the following
page do not reflect the effect of any sales charges. The Fund's average annual
total returns presented in the table below the bar chart reflect the effect of
sales charges. Class A shares are not sold with a sales charge. Both the bar
chart and the table assume that all dividends were reinvested.

From January 25, 1999 through August 17, 2001, Seligman (the predecessor
investment manager), at its discretion, agreed to waive a portion of its
management fee equal to an annual rate of 0.10%.

Between November 12, 2002 (April 30, 2003 in the case of Class R shares) and
July 10, 2003, Seligman voluntarily reimbursed portions of the class-specific
expenses of Class B, C and R shares in order for those Classes to declare
dividends equal to an annual rate of 0.05%. Effective July 10, 2003, the
reimbursement was changed to allow a minimum annual dividend rate of 0.05% for
Class A shares and 0.01% for Class B, C and R shares. Effective July 15, 2004,
the reimbursement was changed to allow a minimum annual dividend rate of 0.09%
for Class B, C and R shares. From December 1, 2004 to February 15, 2005, the
annual minimum annual dividend rate was raised to 0.20% with respect to all
classes of shares. From February 16, 2005 through March 24, 2008, Seligman did
not reimburse the Fund's expenses, and as such, for the period there was no
minimum annual dividend rate. Beginning March 25, 2008, Seligman and, since the
Acquisition, RiverSource Investments (the current investment manager), from
time-to-time and at their discretion, reimbursed certain class-specific expenses
of certain share classes to allow those classes to maintain certain dividend
rates. Absent such expense reimbursements, the dividend rates in respect of such
share classes would have been lower or negative. Absent such reimbursements,
returns presented in the bar chart and table would have been lower.

FEES AND EXPENSES

The table below summarizes the fees and expenses that you may pay as a
shareholder of the Fund. Each Class of shares has its own sales charge schedule
and is subject to different ongoing 12b-1 fees. For more information, see the
Shareholder Information section of the prospectus. Annual fund operating
expenses are deducted from Fund assets and are therefore paid indirectly by you
and other shareholders of the Fund.

The annual fund operating expenses in the fee and expense table below are based
on expenses incurred during the Fund's most recently completed fiscal year,
adjusted to reflect expenses associated with the change in the Fund's transfer
and shareholder service agent, and are expressed as a percentage (expense ratio)
of the Fund's average net assets during the period. The expense ratios have not
been adjusted to reflect the Fund's assets as of a different period or point in
time, as asset levels will fluctuate. As of the date of this prospectus, the
Fund's assets are lower than the Fund's average net assets during the most
recently completed fiscal year. In general, a fund's annual operating expenses
will increase as the fund's assets decrease. Accordingly, the Fund's annual
operating expenses, if adjusted based on assets as of the date of this
prospectus, would be higher than are expressed in the fee and expense table
below. The commitment by the investment manager and its affiliates to waive fees
and cap (reimburse) expenses would limit the impact that any decrease in the
Fund's assets will have on its total annual (net) operating expenses in the
current fiscal year.

Effective on or about June 13, 2009, the Fund's Class R shares are renamed as
Class R2 shares.

As of the date of this prospectus, Ameriprise Financial provides administrative
services to the Fund at no cost and RiverSource Investments provides investment
management services for a fee, as disclosed in the fee table below. Effective in
the second half of 2009, Ameriprise Financial will charge the Fund a fee for its
services (which would be reflected in the Fund's "Other Expenses" in the fee
table below). There will be no net impact to the fees that the Fund will pay
because the administrative fee will be fully offset by a reduction in the
investment management fees charged to the Fund. Please see the Appendices C and
D in the Statement of Additional Information for the schedule of investment
management fees and administrative fees effective in the second half of 2009.

----------
(1) Effective on or about June 13, 2009, the distributor has currently agreed
not to be reimbursed by the Fund for distribution (12b-1) fees equal to
0.15% of the stated amount for Class A shares and 0.25% of the stated
amount for Class B, Class C and Class R shares.

(2) "Other expenses" includes transfer and shareholder service agent fees and
expenses. The Fund's Board approved RiverSource Service Corporation ("RSC")
as the Fund's new transfer and shareholder service agent, and the
termination of the Fund's relationship with Seligman Data Corp. ("SDC"),
the former transfer and shareholder service agent for the Fund, effective
on or about June 13, 2009. RSC is an affiliate of RiverSource Investments.
"Other expenses" is based on estimated fees and expenses of SDC from May
1, 2009 through June 12, 2009 and of RSC from June 13, 2009 through April
30, 2010, and includes non-recurring charges to the Fund resulting from the
termination of SDC as transfer and shareholder service agent for the Fund
(the "Non-Recurring Charges"). SDC or RSC is referred to as the "transfer
agent." The fees and expenses charged to the Fund by RSC are lower than the
fees and expenses charged to the Fund by SDC. The examples of Fund expenses
below reflect the change in expenses resulting from the termination of SDC
and the hiring of RSC.

(3) RiverSource Investments and its affiliates have contractually agreed to
waive certain fees and to absorb certain expenses until April 30, 2010,
unless sooner terminated at the discretion of the Fund's Board. Any amounts
waived will not be reimbursed by the Fund. Under this agreement, net fund
expenses will not exceed 0.66% for Class A, 1.32% for Class B, 1.31% for
Class C and 0.98% for Class R shares.

EXAMPLE

This example is intended to help you compare the costs of investing in the Fund
with the costs of investing in other mutual funds. It assumes (1) you invest
$10,000 in the Fund for each period and then sell all of your shares at the end
of that period, (2) your investment has a 5% return each year, and (3) the
Fund's operating expenses are (i) the Fund's net operating expenses shown above
(which reflects the fee waiver/expense reimbursement, the Non-Recurring
Charges, SDC's estimated fees and expenses from May 1, 2009 through June 12,
2009 and RSC's estimated fees and expenses from June 13, 2009 through April 30,
2010) and (ii) after April 30, 2010, the Fund's total annual operating expenses
shown above adjusted to exclude those fees and expenses no longer applicable to
the Fund (i.e., the fee waiver/expense reimbursement, the Non-Recurring Charges
and SDC's fees and expenses). Although your actual costs may be higher or lower,
based on these assumptions your costs would be:

1 YEAR 3 YEARS 5 YEARS 10 YEARS
------ ------- ------- --------

Class A $ 67 $218 $ 381 $ 856
Class B 634 799 1,087 1,707+
Class C 233 498 886 1,976
Class R 200 338 595 1,329

If you did not sell your shares at the end of each period, your costs would be:

1 YEAR 3 YEARS 5 YEARS 10 YEARS
------ ------- ------- --------

Class A $ 67 $218 $381 $ 856
Class B 134 499 887 1,707+
Class C 133 498 886 1,976
Class R 100 338 595 1,329

----------
+ Class B shares will automatically convert to Class A shares approximately
eight years after purchase.

MANAGEMENT FEES:

Fees paid out of Fund assets to the investment manager to compensate it for
managing the Fund.

12B-1 FEES:

Fees paid by each Class, pursuant to a plan adopted by the Fund under Rule 12b-1
of the Investment Company Act of 1940. The plan allows each Class to pay
distribution and/or service fees for the sale and distribution of its shares and
for providing services to shareholders.

OTHER EXPENSES:

Miscellaneous expenses of running the Fund, including such things as shareholder
account services, registration, custody, auditing and legal fees.

MANAGEMENT

On November 7, 2008, RiverSource Investments completed its Acquisition of
Seligman, 100 Park Avenue, New York, New York 10017. With the Acquisition
completed and shareholders having previously approved (at a special meeting held
on November 3, 2008) a new investment management services agreement between the
Fund and RiverSource Investments (the "Management Agreement"), RiverSource
Investments is the new investment manager of the Fund effective November 7,
2008.

RiverSource Investments, 200 Ameriprise Financial Center, Minneapolis, Minnesota
55474, is also the investment manager of the RiverSource Family of Funds, which
includes the "RiverSource" funds, "RiverSource Partners" funds, "Threadneedle"
funds and the "Seligman" funds, and is a wholly owned subsidiary of Ameriprise
Financial, Inc. (Ameriprise Financial). Ameriprise Financial is a financial
planning and financial services company that has been offering solutions for
clients' asset accumulation, income management and protection needs for more
than 110 years. In addition to managing investments for the RiverSource Family
of Funds, RiverSource Investments manages investments for itself and its
affiliates. For institutional clients, RiverSource Investments and its
affiliates provide investment management and related services, such as separate
account asset management, and institutional trust and custody, as well as other
investment products.

Effective November 7, 2008, the Fund pays RiverSource Investments a fee for
managing its assets (Seligman no longer receives a management fee effective
November 7, 2008). The fee structure under which the Fund paid management fees
has been eliminated. Prior to November 7, 2008, the Fund calculated the fee
rate, as a percentage of the Fund's daily net assets, on a scale of 0.45% to
0.375% based on the average daily net assets of all US registered investment
companies managed by Seligman. Instead, effective November 7, 2008 the Fund pays
RiverSource Investments a management fee equal to an annual rate of 0.40% of the
Fund's average daily net assets. For the year ended December 31, 2008, the
management fee paid by the Fund for investment management services was equal to
an annual rate of 0.42% of the Fund's average daily net assets. From time to
time, Seligman (the predecessor investment manager) and, since the Acquisition,
RiverSource Investments and its affiliates have made reimbursements to certain
share classes in order for those classes to declare dividends equal to selected
minimum annual rates. Beginning March 25, 2008, Seligman and, since the
Acquisition, RiverSource Investments, from time to time and at their discretion,
reimbursed certain class-specific expenses of certain share classes to allow
those classes to maintain certain dividend rates. Absent such expense
reimbursements, the dividend rates in respect of such share classes would have
been lower or negative.

On July 29, 2008, the Fund's Board met to discuss, prior to shareholder
approval, the Management

AFFILIATES OF RIVERSOURCE INVESTMENTS:

RiverSource Fund Distributors, Inc., formerly Seligman Advisors, Inc. (the
"distributor"): A distributor of the Seligman mutual funds and the RiverSource
Family of Funds; responsible for accepting orders for purchases and sales of
Fund shares.

Seligman Data Corp. (SDC):

The Fund's transfer and shareholder service agent through on or about June 12,
2009; provides shareholder account services to the Fund at cost.

RiverSource Service Corporation (RSC):

The Fund's transfer and shareholder service agent effective on or about June 13,
2009; provides or compensates others to provide transfer agency and shareholder
services to the funds in the RiverSource Family of Funds.

Ameriprise Financial:

Provides or compensates others to provide administrative services to the
RiverSource Family of Funds.

Agreement between the Fund and RiverSource Investments. A discussion regarding
the basis for the Board approving the Management Agreement was included in the
Fund's proxy statement, dated August 27, 2008, and is available in the Fund's
annual shareholder report for the year ended December 31, 2008.

REGULATORY MATTERS

In September 2006, the Office of the Attorney General of the State of New York
("NYAG") commenced a civil action in New York State Supreme Court against J. &
W. Seligman & Co. Incorporated (Seligman), Seligman Advisors, Inc. (now known as
RiverSource Fund Distributors, Inc.), Seligman Data Corp. and Brian T. Zino
(collectively, the "Seligman Parties"), alleging, in substance, that the
Seligman Parties permitted various persons to engage in frequent trading and, as
a result, the prospectus disclosure used by the registered investment companies
then managed by Seligman is and has been misleading. The NYAG included other
related claims and also claimed that the fees charged by Seligman to the
Seligman Funds were excessive.

On March 13, 2009, without admitting or denying any violations of law or
wrongdoing, the Seligman Parties entered into a stipulation of settlement with
the NYAG and settled the claims made by the NYAG. Under the terms of the
settlement, Seligman paid $11.3 million to four Seligman Funds as follows:
$150,000 to Seligman Global Growth Fund, $550,000 to Seligman Global Smaller
Companies Fund, $7.7 million to Seligman Communications and Information Fund and
$2.9 million to Seligman Global Technology Fund. These settlement payments are
reflected in the net asset values of these four Seligman Funds. This settlement
resolves all outstanding matters between the Seligman Parties and the NYAG.

In addition to the foregoing matter, the New York staff of the SEC indicated in
September 2005 that it was considering recommending to the Commissioners of the
SEC the instituting of a formal action against Seligman and Seligman Advisors,
Inc. relating to frequent trading in the Seligman Funds. Seligman responded to
the staff in October 2005 that it believed that any action would be both
inappropriate and unnecessary, especially in light of the fact that Seligman had
previously resolved the underlying issue with the Independent Directors of the
Seligman Funds and made recompense to the affected Seligman Funds. There have
been no further developments with the SEC on this matter.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings, including
routine litigation, class actions, and governmental actions, concerning matters
arising in connection with the conduct of their business activities. Ameriprise
Financial believes that the Seligman Funds are not currently the subject of, and
that neither Ameriprise Financial nor any of its affiliates are the subject of,
any pending legal, arbitration or regulatory proceedings that are likely to have
a material adverse effect on the Seligman Funds or the ability of Ameriprise
Financial or its affiliates to perform under their contracts with the Seligman
Funds. Information regarding certain legal proceedings may be found in the
Seligman Funds' shareholder reports and SAIs. Additionally, Ameriprise Financial
is required to make 10-Q, 10-K and, as necessary, 8-K filings with the SEC on
legal and regulatory matters that relate to Ameriprise Financial and its
affiliates. Copies of these filings may be obtained by accessing the SEC website
at www.sec.gov.

Shareholder Information

THIS SHAREHOLDER INFORMATION SECTION IS EFFECTIVE ON OR ABOUT JUNE 13, 2009.

RIVERSOURCE FAMILY OF FUNDS

THE RIVERSOURCE FAMILY OF FUNDS (EACH INDIVIDUALLY A "FUND" AND, COLLECTIVELY,
THE "FUNDS") INCLUDES "RIVERSOURCE" FUNDS, "RIVERSOURCE PARTNERS" FUNDS,
"SELIGMAN" FUNDS AND "THREADNEEDLE" FUNDS. (THE RIVERSOURCE FUNDS, RIVERSOURCE
PARTNERS FUNDS AND THREADNEEDLE FUNDS MAY BE COLLECTIVELY REFERRED TO AS THE
"RIVERSOURCE FUNDS".) THE FUNDS SHARE THE SAME BOARD OF DIRECTORS/TRUSTEES (THE
"BOARD") AND THE SAME POLICIES AND PROCEDURES INCLUDING THOSE SET FORTH IN THE
SERVICE SECTION OF THIS PROSPECTUS. 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
FUNDS IN THE RIVERSOURCE FAMILY OF FUNDS OWNED BY THE INVESTOR AS DEFINED UNDER
"INITIAL SALES CHARGE--RIGHTS OF ACCUMULATION (ROA)."

Effective on or about June 13, 2009, the Seligman funds' Class R shares will be
renamed as Class R2 shares and the Seligman funds' Class I shares (which are
offered in a separate prospectus) will be renamed as Class R5 shares. At such
time, the Fund will then offer the following classes of shares: Class A, Class
B, Class C, Class R2 and Class R5 shares.

Buying And Selling Shares

The funds are available directly and through broker-dealers, banks and other
financial intermediaries or institutions (financial intermediaries), and through
certain qualified and non-qualified plans, wrap fee products or other investment
products sponsored by financial intermediaries. NOT ALL FINANCIAL INTERMEDIARIES
OFFER THE FUNDS. FINANCIAL INTERMEDIARIES THAT OFFER THE FUNDS MAY CHARGE YOU
ADDITIONAL FEES FOR THE SERVICES THEY PROVIDE AND THEY MAY HAVE DIFFERENT
POLICIES NOT DESCRIBED IN THIS PROSPECTUS. Some policy differences may include
different minimum investment amounts, exchange privileges, fund choices and
cutoff times for investments. Additionally, recordkeeping, transaction
processing and payments of distributions relating to your account may be
performed by the financial intermediaries through which your shares of the fund
are held. Since the fund (and its service providers) may not have a record of
your account transactions, you should always contact the financial intermediary
through which you purchased or at which you maintain your shares of the fund to
make changes to your account or to give instructions concerning your account, or
to obtain information about your account. The fund and its service providers,
including the distributor and the transfer agent, are not responsible for the
failure of one of these financial intermediaries to carry out its obligations to
its customers.

DESCRIPTION OF SHARE CLASSES

INVESTMENT OPTIONS--CLASSES OF SHARES

The funds offer different classes of shares. There are differences among the
fees and expenses for each share class. See the "Fees and Expenses" table for
more information. Not everyone is eligible to buy every share class. After
determining which share classes you are eligible to buy, decide which share
class best suits your needs. Your financial advisor can help you with this
decision. The following table shows the key features of each share class. Not
all funds offer all classes of shares.

----------
(a) See "Buying and Selling Shares, Determining which class of shares to
purchase" for more information on availability of share classes and
eligible investors. See "Buying and Selling Shares, Opening an Account"
for information on minimum investment and account balance requirements.

(b) For each of Class A, Class B, Class C, Class R2, Class R3 and Class W
shares, as applicable, each fund has adopted a plan under Rule 12b-1 of the
Investment Company Act of 1940, as amended, that allows it to pay
distribution and shareholder servicing-related expenses for the sale of
shares and the servicing of shareholders. This plan has been reviewed and
approved by the Board. Because these fees are paid out of fund assets on an
on-going basis, over time these fees will increase the cost of your
investment and may cost you more than paying other types of distribution
(sales) or servicing charges.

(c) A 1% CDSC may be assessed on Class A shares sold within 18 months after
purchase. See "Buying and Selling Shares, Sales Charges, Class
A--contingent deferred sales charge" for more information. For all funds
except money market funds.

(d) Class B shares automatically convert to Class A shares. See "Buying and
Selling Shares, Sales Charges, Class B and Class C--CDSC alternative" for
more information on the timing of conversion of Class B shares to Class A
shares. Timing of conversion will vary depending on the date of your
original purchase of the Class B shares.

(e) Class B shares of RiverSource Absolute Return Currency and Income Fund are
only available for exchanges from Class B shares of another fund in the
RiverSource Family of Funds. Class B shares of each of RiverSource Floating
Rate Fund, RiverSource Inflation Protected Securities Fund, RiverSource
Intermediate Tax-Exempt Fund, RiverSource Limited Duration Bond Fund and
RiverSource Short Duration U.S. Government Fund are closed to new investors
and new purchases. (Existing shareholders in these funds may continue to
own Class B shares and make exchanges into and out of existing accounts
where Class B shares of these funds are maintained.)

(f) The money market funds may offer Class B and Class C shares, but only to
facilitate exchanges with other funds offering Class B and Class C shares,
respectively.

(g) Effective on or about June 13, 2009, the Seligman funds' Class R shares
will be renamed as Class R2 shares.

(h) Effective on or about June 13, 2009, the Seligman funds' Class I shares
will be renamed as Class R5 shares.

(i) For RiverSource Cash Management Fund and RiverSource Tax-Exempt Money
Market Fund, Class A is 0.10%. For RiverSource Cash Management Fund, Class
B is 0.85%, Class C is 0.75% and Class W is 0.10%.

DISTRIBUTION AND SERVICE FEES

The distribution and shareholder servicing fees for Class A, Class B, Class C,
Class R2, Class R3 and Class W shares, as applicable, 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 and
up to 0.25%* of the average daily net assets of Class A, Class B, Class C, Class
R3 and Class W shares sold and held through them. For Class A, Class B, Class
R2, Class R3 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. Financial intermediaries 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 fund's distributor retains the distribution fee of up to
0.75% in order to finance the payment of sales commissions to financial
intermediaries, and to pay for other distribution related expenses. Financial
intermediaries may compensate their financial advisors with the shareholder
servicing 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 INTERMEDIARY OR FINANCIAL ADVISOR, DISTRIBUTION AND SERVICE FEES MAY
BE RETAINED BY THE DISTRIBUTOR AS REIMBURSEMENT FOR INCURRING CERTAIN
DISTRIBUTION AND SHAREHOLDER SERVICING RELATED EXPENSES.

PLAN ADMINISTRATION FEE

Class R2, Class R3, Class R4 and Class Y shares pay an annual plan
administration services fee for the provision of various administrative,
recordkeeping, communication and educational services. The fee for Class R2,
Class R3 and Class R4 shares is equal on an annual basis to 0.25% of average
daily net assets attributable to the respective class. The fee for Class Y
shares is equal on an annual basis to 0.15% of average daily net assets
attributable to the class.

DETERMINING WHICH CLASS OF SHARES TO PURCHASE

Each of the fund's classes represent an interest in the same portfolio of
investments. However, as set forth above, each class has its own sales charge
schedule, and its ongoing distribution and shareholder service fees may differ
from other classes. When deciding which class of shares to buy, you should
consider, among other things:

The amount you plan to invest.

How long you intend to remain invested in the fund or another fund in the
RiverSource Family of Funds.

Whether you may be eligible for reduced or no sales charges when you buy or
sell shares.

Your authorized financial intermediary or financial advisor will be able to help
you decide which class of shares best meets your needs.

----------
* For RiverSource Cash Management Fund, financial intermediaries receive fees
up to 0.10% of the average daily net assets of Class A, Class B and Class W
shares sold and held through them.

CLASS A, CLASS B AND CLASS C SHARES*

Class B shares of RiverSource Absolute Return Currency and Income Fund are not
currently available for new purchases. However, if you own class B shares of
another fund in the RiverSource Family of Funds, you may exchange into Class B
shares of RiverSource Absolute Return Currency and Income Fund, if you meet the
minimum investment and account balance requirements set forth in "Opening an
Account," subject to the limitations set forth in this section. New purchases of
Class B shares will not be permitted if your rights of accumulation are $50,000
or higher, and new purchases of Class C shares will not be permitted if your
rights of accumulation are $1,000,000 or higher. See "Sales Charges, Initial
Sales Charge--Rights of Accumulation" for information on rights of accumulation.

Class B shares have a higher annual distribution fee than Class A shares and a
contingent deferred sales charge (CDSC) for six years. Class B shares convert to
Class A shares. Class B shares purchased through reinvested dividends and
distributions will convert to Class A shares in the same proportion as the other
Class B shares. See "Class B and Class C--CDSC alternative" for information on
timing of Class B share conversion to Class A shares.

Class C shares have a higher annual distribution fee than Class A shares and a
CDSC for one year. Class C shares have no sales charge if you hold the shares
for longer than one year. Unlike Class B shares, Class C shares do not convert
to Class A shares. As a result, you will pay a distribution fee for as long as
you hold Class C shares.

If you choose a share class with a CDSC (Class B or Class C), you should
consider the length of time you intend to hold your shares. To help you
determine which investment is best for you, consult your financial intermediary
or financial advisor.

CLASS I SHARES.

The following eligible investors may purchase Class I shares:

Any fund distributed by the distributor, if the fund seeks to achieve its
investment objective by investing primarily in shares of funds in the
RiverSource Family of Funds.

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

CLASS R AND CLASS Y SHARES.

The following eligible institutional investors may purchase Class R2, Class R3,
Class R4, Class R5 and Class Y 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.

----------
* For money market funds, new investments must be made in Class A shares of
the fund. The fund offers Class B and Class C shares only to facilitate
exchanges between classes of these shares in other funds.

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

Additionally, if approved by the distributor, the following eligible
institutional investors may purchase Class R5 shares:

Institutional or corporate accounts above a threshold established by the
distributor (currently $1 million per fund or $10 million in all funds in
the RiverSource Family of Funds).

Bank trust departments.

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

CLASS W SHARES.

The following eligible investors may purchase Class W shares:

Investors purchasing through authorized investment programs managed by
investment professionals, including discretionary managed account programs.

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

Shares originally purchased in a discretionary managed account may continue to
be held in Class W outside of a discretionary managed account, but no additional
Class W purchases may be made and no exchanges to Class W shares of another fund
may be made outside of a discretionary managed account.

IN ADDITION, FOR CLASS I, CLASS R, CLASS W AND CLASS Y SHARES, THE DISTRIBUTOR,
IN ITS SOLE DISCRETION, MAY ACCEPT OR AUTHORIZE FINANCIAL INTERMEDIARIES TO
ACCEPT INVESTMENTS FROM OTHER PURCHASERS NOT LISTED ABOVE.

Please consult your financial advisor for assistance in selecting the
appropriate class of shares. For more information, see the SAI.

NON-MONEY MARKET FUNDS

CLASS A--INITIAL SALES CHARGE ALTERNATIVE:

Your purchase price for Class A shares is generally the net asset value (NAV)
plus a front-end sales charge. The distributor receives the sales charge and
re-allows a portion of the sales charge to the financial intermediary through
which you purchased the shares. The distributor retains the balance of the sales
charge. The distributor retains the full sales charge you pay when you purchase
shares of the fund directly from the fund (not through an authorized financial
intermediary). Sales charges vary depending on the amount of your purchase.

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

(b) Purchase price includes the sales charge.

(c) Although there is no sales charge for purchases with a total market value
over $1,000,000, and therefore no re-allowance, the distributor may pay a
financial intermediary the following out of its own resources: a sales
commission of up to 1.00% for a sale of $1,000,000 to $3,999,999; a sales
commission up to 0.50% for a sale of $4,000,000 to $49,999,999; and a sales
commission up to 0.25% for a sale of $50,000,000 or more.

(d) For certain eligible employee benefit plans defined under section 401(a),
401(k), 457 and 403(b) which meet eligibility rules for the waiver of
applicable sales charges, the distributor may pay the following out of its
own resources: a sales commission of 1.00% for a sale of $1 to $3,999,999
received in eligible employee benefit plans; a sales commission up to 0.50%
for a sale of $4,000,000 to $49,999,999; and a sales commission up to 0.25%
for a sale of $50,000,000 or more. See "Initial Sales Charge--Waivers of
the sales charge for Class A shares" for employee benefit plan eligibility
rules.

There is no initial sales charge on reinvested dividends or capital gain
distributions.

INITIAL SALES CHARGERIGHTS OF ACCUMULATION (ROA). You may be able to reduce the
sales charge on Class A shares, based on the combined market value of accounts
in your ROA group. Your ROA group includes the current market values of the
following investments which are eligible to be added together for purposes of
determining the sales charge on your next purchase:

Your current investment in a fund; and

Previous investments you and members of your household have made in Class
A, Class B or Class C shares in the fund and other funds in the RiverSource
Family of Funds, provided your investment was subject to a sales charge.
Your household consists of you, your spouse or domestic partner and your
unmarried children under age 21, all of whom share a mailing address.

The following accounts are eligible to be included in your ROA group in order to
determine the sales charge on your purchase:

Individual or joint accounts;

Roth and traditional IRAs, SEPs, SIMPLEs and TSCAs, provided they are
invested in Class A, Class B or Class C shares that were subject to a sales
charge;

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

Revocable trust accounts for which you or a member of your household,
individually, is the beneficial owner/grantor;

Accounts held in the name of your, your spouse's, or your domestic
partner's sole proprietorship or single owner limited liability company or
S corporation; and

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

The following accounts are NOT eligible to be included in your ROA group in
order to determine the sales charge on your purchase:

Accounts of pension and retirement plans with multiple participants, such
as 401(k) plans (which are combined to reduce the sales charge for the
entire pension or retirement plan and therefore are not used to reduce the
sales charge for your individual accounts);

Investments in Class A shares where the sales charge is waived, for
example, purchases through wrap accounts;

Investments in Class I, Class R2, Class R3, Class R4, Class R5, Class W or
Class Y shares;

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

Charitable and irrevocable trust accounts.

If you purchase fund shares through different financial intermediaries, and you
want to include those assets toward a reduced sales charge, you must inform your
financial intermediary in writing about the other accounts when placing your
purchase order. Contact your financial intermediary to determine what
information is required.

Unless you provide your financial intermediary in writing with information about
all of the accounts that may count toward a sales charge reduction, there can be
no assurance that you will receive all of the reductions for which you may be
eligible. You should request that your financial intermediary provide this
information to the fund when placing your purchase order.

For more information on ROA, please see the SAI.

INITIAL SALES CHARGE--LETTER OF INTENT (LOI). Generally, if you intend to
invest $50,000 or more (including any existing ROA) over a period of up to 13
months, you may be able to reduce the front-end sales charge(s) for investments
in Class A

shares by completing and filing an LOI. The required form of LOI may vary by
financial intermediary. Existing ROA can be included in your LOI. Each purchase
of fund shares normally subject to an initial sales charge made during the
13-month period will be made at the public offering price applicable to a single
transaction of the total dollar amount indicated by the LOI. Five percent of the
commitment amount will be placed in escrow. At the end of the 13-month period,
the LOI will end and the shares will be released from escrow. If you do not
invest the commitment amount by the end of the 13 months, the remaining amount
of the unpaid sales charge will be redeemed from the escrowed shares and the
remaining balance released from escrow.

EXISTING ROA EXAMPLE. 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 (any non-money market fund in the RiverSource Family of Funds) in
order to fulfill the LOI commitment and receive reduced front-end sales
charge(s) over the next 13 months.

NOTIFICATION OBLIGATION. You must request the reduced sales charge when you buy
shares. If you do not complete and file an LOI, or do not request the reduced
sales charge at the time of purchase, you will not be eligible for the reduced
sales charge. You should request that your financial intermediary provide this
information to the fund when placing your purchase order. For more detail on
LOIs, please contact your financial intermediary or see the SAI.

For more information regarding waivers of sales charge for Class A purchases,

The distributor may, in its sole discretion, authorize the waiver of sales
charges for additional classes of investors. Policies related to reducing or
waiving the sales charge may be modified or withdrawn at any time.

Unless you provide your financial intermediary with information in writing about
all of the factors that may count toward a waiver of the sales charge, there can
be no assurance that you will receive all of the waivers for which you may be
eligible. You should request that your financial intermediary provide this
information to the fund when placing your purchase order.

Because the current prospectus is available on the funds' website (for
RiverSource funds) at riversource.com/fund or (for Seligman funds) at
seligman.com free of charge, information regarding breakpoint discounts is not
separately disclosed on the website.

CLASS A--CONTINGENT DEFERRED SALES CHARGE

For Class A shares purchased without a sales charge where a commission was
separately paid by the distributor to an authorized financial intermediary
effecting the purchase, a 1% CDSC may be charged if you sell your shares within
18 months after purchase. A CDSC will be based on the original purchase cost or
the current market value of the shares being sold, whichever is less.

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

to which no sales commission or transaction fee was paid to an authorized
financial intermediary at the time of purchase.

purchased through reinvestment of dividends and capital gain distributions.

in the event of the shareholder's death.

from a monthly, quarterly or annual systematic redemption plan of up to an
annual amount of 12% of the account value on a per fund basis.

in an account that has been closed because it falls below the minimum
account balance.

that result from required minimum distributions taken from retirement
accounts upon the shareholders attainment of age 70 1/2.

that result from returns of excess contributions or excess deferral amounts
made to a retirement plan participant.

of RiverSource funds purchased prior to Dec. 1, 2008.

initially purchased by an employee benefit plan that is not connected with
a plan level termination.

The distributor may, in its sole discretion, authorize the waiver of the CDSC
for additional classes of investors. Policies relating to waiving the CDSC may
be modified or withdrawn at any time.

CLASS B AND CLASS C--CDSC ALTERNATIVE

The money market funds (except RiverSource Tax-Exempt Money Market Fund) offer
Class B and Class C shares, but only to facilitate exchanges with other funds
offering Class B and Class C shares, respectively. For example, if you own Class
B or Class C shares of another fund, but want to hold your money in a money
market fund, you may exchange into Class B or Class C shares of a money market
fund. Funds that offer Class B and Class C shares have limitations on the amount
you may invest in those share classes. If you are

considering purchasing Class B or Class C shares of a fund, please see the
prospectus for that fund for any effective purchase limitations.

Although you may not purchase Class B and Class C shares of the money market
funds directly, if you exchange into Class B or Class C shares of a money market
fund from another fund, you will be subject to the rules governing CDSC set
forth in this section.

To minimize the amount of CDSC you may pay when you sell your shares, the fund
assumes that shares acquired through reinvested dividends and capital gain
distributions (which are not subject to CDSC) are sold first. Shares that have
been in your account long enough so that they are not subject to a CDSC are sold
next. After these shares are exhausted, shares will be sold in the order they
were purchased (earliest to latest).

FOR CLASS B, the CDSC is based on the sale amount and the number of years
between purchase and sale. The following table shows how CDSC percentages on
sales decline over time:

IF THE SALE IS MADE DURING THE: THE CDSC PERCENTAGE RATE IS:*
------------------------------- -----------------------------

First year 5%
Second year 4%
Third year 3%**
Fourth year 3%
Fifth year 2%
Sixth year 1%
Seventh or eighth year 0%

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

** For shares purchased in a RiverSource fund prior to June 12, 2009, the CDSC
percentage for the third year is 4%.

Although there is no front-end sales charge when you buy Class B shares, the
distributor pays a sales commission of 4% to financial intermediaries that sell
Class B shares. A portion of this commission may, in turn, be paid to your
financial advisor. The distributor receives any CDSC imposed when you sell your
Class B shares.

You may not make additional purchases of Class B shares if your ROA exceeds
$49,999.99.

Class B shares purchased in a RiverSource fund prior to May 21, 2005 age on a
calendar year basis. Class B shares purchases made in a RiverSource fund
beginning May 21, 2005 age on a daily basis. For example, a purchase made on
Nov. 12, 2004 completed its first year on Dec. 31, 2004 under calendar year
aging. However, a purchase made on Nov. 12, 2005 completed its first year on
Nov. 11, 2006 under daily aging.

Class B shares originally purchased in a RiverSource fund prior to May 21, 2005
will convert to Class A shares in the ninth calendar year of ownership. Class B
shares originally purchased in a Seligman fund on or prior to June 12, 2009 will
convert to Class A shares in the month prior to the ninth year of ownership.
Class B shares purchased in a RiverSource fund beginning May 21, 2005 and Class
B shares purchased in a Seligman fund beginning June 13, 2009 will convert to
Class A shares one month after the completion of the eighth year of ownership.

FOR CLASS C, a 1% CDSC may be charged if you sell your shares within one year
after purchase. Although there is no front-end sales charge when you buy Class C
shares, the distributor pays a total amount up to 1% (including sales commission
and advance of service fees) to financial intermediaries that sell Class C
shares. See "Buying and Selling Shares--Distribution and Service Fees." A
portion

of this commission may, in turn, be paid to your financial advisor. The
distributor receives any CDSC imposed when you sell your Class C shares. You may
not make additional purchases of Class C shares if your ROA exceeds $999,999.99.

For both Class B and Class C shares, the amount of any CDSC you pay will be
based on the lower of the original purchase price of those shares or current net
asset value. Because the CDSC is imposed only on sales that reduce your total
purchase payments, you do not have to pay a CDSC on any amount that represents
appreciation in the value of your shares, income earned by your shares, or
capital gains. In addition, the CDSC on your sale, if any, will be based on your
oldest purchase payment. The CDSC on the next amount sold will be based on the
next oldest purchase payment.

EXAMPLE

Assume you had invested $10,000 in Class B shares and that your investment had
appreciated in value to $12,000 after 3 1/2 years, including reinvested
dividends and capital gain distributions. You could sell up to $2,000 worth of
shares without paying a CDSC ($12,000 current value less $10,000 purchase
amount). If you sold $2,500 worth of shares, the CDSC would apply to the $500
representing part of your original purchase price. The CDSC rate would be 3%
because the sale was made during the fourth year after the purchase.

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

in the event of the shareholder's death.

that result from required minimum distributions taken from retirement
accounts upon the shareholders' attainment of age 70 1/2.

sold under an approved substantially equal periodic payment arrangement.

by certain other investors, including certain institutions as set forth in
more detail in the SAI.

The distributor may, in its sole discretion, authorize the waiver of the CDSC
for additional classes of investors. Policies relating to waiving the CDSC may
be modified or withdrawn at any time.

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

in the event of the shareholder's death.

to which no sales commission or transaction fee was paid to an authorized
financial intermediary at the time of purchase.

that result from required minimum distributions taken from retirement
accounts upon the shareholders' attainment of age 70 1/2.

initially purchased by an eligible employee benefit plan that are not
connected with a plan level termination.

by certain other investors, including certain institutions as set forth in
more detail in the SAI.

The distributor may, in its sole discretion, authorize the waiver of the CDSC
for additional classes of investors. Policies relating to waiving the CDSC may
be modified or withdrawn at any time.

CLASS I, CLASS R2, CLASS R3, CLASS R4, CLASS R5, CLASS W AND CLASS Y--NO SALES
CHARGE. For each of Class I, Class R2, Class R3, Class R4, Class R5, Class W and
Class Y there is no initial sales charge or CDSC.

The fund's Board believes that no conflict of interest currently exists between
the fund's classes of shares. On an ongoing basis, the Board, in the exercise of
its fiduciary duties, seeks to ensure that no such conflicts arise.

OPENING AN ACCOUNT

Financial institutions are required by law to obtain certain personal
information from each person who opens an account in order to verify the
identity of the person. As a result, when you open an account you will be asked
to provide your name, permanent street address, date of birth, and Social
Security or Employer Identification number. You may also be asked for other
identifying documents or information. If you do not provide this information,

the fund or the financial intermediary through which you are investing in the
fund may not be able to open an account for you. If the fund or the financial
intermediary through which you are investing in the fund is unable to verify
your identity, your account may be closed, or other steps may be taken, as
deemed appropriate.

When you buy shares, your order will be priced at the next NAV calculated after
your order is accepted by the fund or an authorized financial intermediary. Any
applicable sales charge will be added to the purchase price for Class A shares.

You may establish and maintain your account with an authorized financial
intermediary or directly with the fund. The fund may appoint servicing agents to
accept purchase orders and to accept exchange (and sale) orders on its behalf.
Accounts established with the fund will be supported by the fund's transfer
agent.

METHODS OF PURCHASING SHARES

These methods of purchasing shares generally apply to Class A, Class B, and
Class C shares.

MARKET TIMING

SHORT-TERM TRADING AND OTHER SO-CALLED MARKET TIMING PRACTICES ARE FREQUENT
TRADING PRACTICES BY CERTAIN SHAREHOLDERS INTENDED TO PROFIT AT THE EXPENSE OF
OTHER SHAREHOLDERS BY SELLING SHARES OF A FUND SHORTLY AFTER PURCHASE. MARKET
TIMING MAY ADVERSELY IMPACT A FUND'S PERFORMANCE BY PREVENTING THE INVESTMENT
MANAGER FROM FULLY INVESTING THE ASSETS OF THE FUND, DILUTING THE VALUE OF
SHARES HELD BY LONG-TERM SHAREHOLDERS, OR INCREASING THE FUND'S TRANSACTION
COSTS.

FOR A FUND ORGANIZED AS A FUND-OF-FUNDS, ITS ASSETS CONSIST PRIMARILY OF SHARES
OF THE UNDERLYING FUNDS IN WHICH IT INVESTS. THE UNDERLYING FUNDS MAY BE MORE
SUSCEPTIBLE TO THE RISKS OF MARKET TIMING. FUNDS THAT INVEST DIRECTLY IN
SECURITIES THAT TRADE INFREQUENTLY MAY BE VULNERABLE TO MARKET TIMERS WHO SEEK
TO TAKE ADVANTAGE OF INEFFICIENCIES IN THE SECURITIES MARKETS. FUNDS AND THE
UNDERLYING FUNDS THAT INVEST IN SECURITIES THAT TRADE ON OVERSEAS SECURITIES
MARKETS MAY BE VULNERABLE TO MARKET

TIMERS WHO SEEK TO TAKE ADVANTAGE OF CHANGES IN THE VALUES OF SECURITIES BETWEEN
THE CLOSE OF OVERSEAS MARKETS AND THE CLOSE OF U.S. MARKETS, WHICH IS GENERALLY
THE TIME AT WHICH A FUND'S NAV IS CALCULATED. TO THE EXTENT THAT A FUND OR
UNDERLYING FUND HAS SIGNIFICANT HOLDINGS OF SMALL CAP STOCKS, FLOATING RATE
LOANS, HIGH YIELD BONDS, TAX-EXEMPT SECURITIES OR FOREIGN SECURITIES, THE RISKS
OF MARKET TIMING MAY BE GREATER FOR THE FUND THAN FOR OTHER FUNDS. SEE
"PRINCIPAL INVESTMENT STRATEGIES" FOR A DISCUSSION OF THE TYPES OF SECURITIES IN
WHICH YOUR FUND INVESTS. SEE "PRICING AND VALUING OF FUND SHARES" FOR A
DISCUSSION OF THE FUNDS' POLICY ON FAIR VALUE PRICING, WHICH IS INTENDED, IN
PART, TO REDUCE THE FREQUENCY AND EFFECT OF MARKET TIMING.

THE FUNDS' BOARD HAS ADOPTED A POLICY THAT IS DESIGNED TO DETECT AND DETER
MARKET TIMING THAT MAY BE HARMFUL TO THE FUNDS. EACH FUND SEEKS TO ENFORCE THIS
POLICY THROUGH ITS SERVICE PROVIDERS AS FOLLOWS:

The fund tries to distinguish market timing from trading that it believes
is not harmful, such as periodic rebalancing for purposes of asset
allocation or dollar cost averaging or other purchase and exchange
transactions not believed to be inconsistent with the best interest of fund
shareholders or the Board's policy. The fund uses a variety of techniques
to monitor for and detect abusive trading practices. These techniques may
vary depending on the type of fund, the class of shares and where the
shares are maintained. Under the fund's procedures, there is no set number
of transactions in the fund that constitutes market timing. Even one
purchase and subsequent sale by related accounts may be market timing.
Generally, the fund seeks to restrict the exchange privilege of an investor
who makes more than three exchanges into or out of the fund in any 90-day
period. Accounts held by a retirement plan or a financial intermediary for
the benefit of its participants or clients, which typically engage in daily
transactions, are not subject to this limit, although the fund may seek the
assistance of financial intermediaries in applying similar restrictions on
their participants or clients. The fund's ability to monitor and discourage
abusive trading practices in omnibus accounts is more limited.

The fund may rely on the monitoring policy of a financial intermediary, for
example, a retirement plan administrator or similar financial intermediary
authorized to distribute the funds, if it determines the policy and
procedures of such financial intermediaries are sufficient to protect the
fund and its shareholders.

If an investor's trading activity is determined to be market timing or
otherwise harmful to existing shareholders, the fund reserves the right to
modify or discontinue the investor's exchange privilege or reject the
investor's purchases or exchanges, including purchases or exchanges
accepted by a financial intermediary. The fund may treat accounts it
believes to be under common control as a single account for these purposes,
although it may not be able to identify all such accounts.

Although the fund does not knowingly permit market timing, it cannot
guarantee that it will be able to identify and restrict all short-term
trading activity. The fund receives purchase and sale orders through
financial intermediaries where market timing activity may not always be
successfully detected.

Other exchange policies:

Exchanges must be made into the same class of shares of the share class
being exchanged out of.

Exchanges into RiverSource Tax-Exempt Money Market Fund may be made only
from Class A shares.

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

Once the fund receives your exchange request, you cannot cancel it after
the market closes.

Shares of the purchased fund may not be used on the same day for another
exchange or sale.

New investments in Class A shares of a money market fund may be exchanged
for either Class A, Class B or Class C shares of any other publicly offered
fund in the RiverSource Family of Funds.

If you exchange shares from Class A shares of a money market fund to
another fund in the RiverSource Family of Funds, any further exchanges must
be between shares of the same class. For example, if you exchange from
Class A shares of a money market fund into Class B shares of another fund
in the RiverSource Family of Funds, you may not exchange from Class B
shares of that fund back to Class A shares of a money market fund. Exchange
rules for money market funds are illustrated in the following tables.

Shares of Class W originally purchased, but no longer held in a
discretionary managed account, may not be exchanged for Class W shares of
another fund. You may continue to hold these shares in the fund. Changing
your investment to a different fund will be treated as a sale and purchase,
and you will be subject to applicable taxes on the sale and sales charges
on the purchase of the new fund.

If your shares are subject to a CDSC, you will not be charged a CDSC upon
the exchange of those shares. Any CDSC will be deducted when you sell the
shares you received from the exchange. The CDSC imposed at that time will
be based on the period that begins when you bought shares of the original
fund and ends when you sell the shares of the fund you exchanged to.

FROM OTHER FUNDS CLASS A CLASS B CLASS C
------------------------ ------- ------- -------

Class A Yes No No

If your initial investment was in a money market fund and you exchange into an
equity or fixed income fund, you will pay an initial sales charge if you
exchange into Class A and be subject to a CDSC if you exchange into Class B or
Class C.

If your initial investment was in Class A shares of an equity or fixed income
fund and you exchange shares into a money market fund, you may exchange that
amount to another fund, including dividends earned on that amount, without
paying a sales charge.

SELLING SHARES

You may sell your shares at any time. The payment will be sent within seven days
after your request is received in good order. When you sell shares, the amount
you receive may be more or less than the amount you invested. Your sale price
will be the next NAV calculated after your request is received in good order,
minus any applicable CDSC.

REPURCHASES. You can change your mind after requesting a sale of shares and use
all or part of the sale proceeds to purchase new shares of a fund in the
RiverSource Family of Funds. If your original purchase was in Class A or Class
B, you may use all or part of the sale proceeds to purchase new Class A shares
in any fund account linked together for ROA purposes. Your repurchase will be in
Class A shares at NAV, up to the amount of the sale proceeds. For a Class A
repurchase on shares that were originally charged a CDSC, the amount of the CDSC
will be reinvested at the NAV on the date the

repurchase is processed. Repurchases of Class B shares will also be in Class A
shares at NAV. Any CDSC paid upon redemption of your Class B shares will not be
reimbursed. If your original purchase was in Class C, you will be allowed to
reinvest in the same Class C account and fund you originally purchased. In a
Class C repurchase, the CDSC you paid will be reinvested and the shares will be
deemed to have the original cost and purchase date for purposes of applying the
CDSC (if any) to subsequent redemptions. Systematic withdrawals and purchases
will be excluded from this policy.

In order for you to take advantage of this repurchase waiver, you must notify
your financial intermediary or the fund's transfer agent if your account is held
at the fund within 90 days of the date your sale request was processed. Contact
your financial intermediary for information on required documentation. The
repurchase privilege may be modified or discontinued at any time and use of this
option may have tax consequences.

If you sold shares of a Seligman fund on or before February 3, 2009 and wish to
repurchase shares, you have the option of taking advantage of the current
repurchase policy (described above) within 90 days of the date your sale request
was processed, or you may use all or part of your sale proceeds to purchase
shares of the fund you sold or any other fund in the RiverSource Family of Funds
without paying an initial sales charge or, if you paid a CDSC when you sold your
shares, receiving a credit for the applicable CDSC, within 120 days of the date
your sale request was processed. Contact your financial intermediary or, if you
opened an account directly with the fund, the transfer agent, for more

The fund reserves the right to redeem in kind.

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

Pricing and Valuing of Fund Shares

For classes of shares sold with an initial sales charge, the public offering or
purchase price is the net asset value plus the sales charge. For funds or
classes of shares sold without an initial sales charge, the public offering
price is the NAV.

Orders in good form are priced at the NAV next determined after you place your
order. Good form or good order means that your instructions have been received
in the form required by the fund. This may include, for example, providing the
fund name and account number, the amount of the transaction and all required
signatures.

The NAV is the value of a single share of the fund. The NAV is determined by
dividing the value of the fund's assets, minus any liabilities, by the number of
shares outstanding. The NAV is calculated as of the close of business on the New
York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time, on each day that
the NYSE is open. For a fund organized as a fund-of-funds, the assets will
consist primarily of shares of the underlying funds, which are valued at their
NAVs. Securities are valued primarily on the basis of market quotations and
floating rate loans are valued primarily on the basis of indicative bids. Both
market quotations and indicative bids are obtained from outside pricing services
approved and monitored under procedures adopted by the Board. Certain short-term
securities with maturities of 60 days or less are valued at amortized cost.

When reliable market quotations or indicative bids are not readily available,
investments are priced at fair value based on procedures adopted by the Board.
These procedures are also used when the value of an investment held by a fund or
underlying fund is materially affected by events that occur after the close of a
securities market but prior to the time as of which the fund's or underlying
fund's NAV is determined. Valuing investments at fair value involves reliance on
judgment. The fair value of an investment is likely to differ from any available
quoted or published price. To the extent that a fund or an underlying fund has
significant holdings of small cap stocks, high yield bonds, floating rate loans,
tax-exempt securities or foreign securities that may trade infrequently, fair
valuation may be used more frequently than for other funds. The funds use an
unaffiliated service provider to assist in determining fair values for foreign
securities.

Foreign investments are valued in U.S. dollars. Some of a fund's or an
underlying fund's securities may be listed on foreign exchanges that trade on
weekends or other days when the fund does not price its shares. In that event,
the NAV of the fund's or underlying fund's shares may change on days when
shareholders will not be able to purchase or sell the fund's or underlying
fund's shares.

For money markets funds--The fund's investments are valued at amortized cost,
which approximates market value, as explained in the SAI. Although the fund
cannot guarantee it will always be able to maintain a constant net asset value
of $1 per share, it will use its best efforts to do so.

Distributions and Taxes

As a shareholder you are entitled to your share of your fund's net income and
net gains. Each fund distributes dividends and capital gains to qualify as a
regulated investment company and to avoid paying corporate income and excise
taxes.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Your fund's net investment income is distributed to you as dividends. Dividends
may be composed of qualified dividend income, which is eligible for preferential
tax rates under current tax law, as well as other ordinary dividend income,
which may include dividends which are non-qualified dividends, interest income
and short-term capital gains. Because of the types of income earned by fixed
income funds, it is unlikely the funds will distribute qualified dividend
income. Generally, capital gains are realized when a security is sold for a
higher price than was paid for it. Generally, capital losses are realized when a
security is sold for a lower price than was paid for it. Typically, each
realized capital gain or loss is long-term or short-term depending on the length
of time the fund held the security. Realized capital gains and losses offset
each other. The fund offsets any net realized capital gains by any available
capital loss carryovers. Net short-term capital gains, if any, are included in
net investment income and are taxable as ordinary income when distributed to the
shareholder. Net realized long-term capital gains, if any, are distributed by
the end of the calendar year as capital gain distributions. If the fund's
distributions exceed its current and accumulated earnings and profits, that
portion of the fund's distributions will be treated as a return of capital to
the shareholders to the extent of their basis in their shares. A return of
capital will generally not be taxable; however, any amounts received in excess
of basis are treated as capital gain. Forms 1099 sent to shareholders report any
return of capital.

Certain derivative instruments subject the fund to special tax rules, the effect
of which may be to accelerate income to the fund, defer fund losses, cause
adjustments in the holding periods of fund securities, convert capital gains
into ordinary income and convert short-term capital losses into long-term
capital losses. These rules could therefore affect the amount, timing and
character of distributions to shareholders.

REINVESTMENTS

Dividends and capital gain distributions are automatically reinvested in
additional shares in the same class of the fund unless you request distributions
in cash. The financial intermediary through which you purchased shares may have
different policies.

Distributions are reinvested at the next calculated NAV after the distribution
is paid. If you choose cash distributions, you will receive cash only for
distributions declared after your request has been processed.

TAXES

If you buy shares shortly before the record date of a distribution, you may pay
taxes on money earned by the fund before you were a shareholder. You will pay
the full pre-distribution price for the shares, then receive a portion of your
investment back as a distribution, which may be taxable.

For tax purposes, an exchange is considered a sale and purchase, and may result
in a gain or loss. A sale is a taxable transaction. Generally, if you sell
shares for less than their cost, the difference is a capital loss or if

you sell shares for more than their cost, the difference is a capital gain. Your
gain may be short term (for shares held for one year or less) or long term (for
shares held for more than one year).

You may not create a tax loss or reduce a tax gain, based on paying a sales
charge, by exchanging shares before the 91st day after the day of purchase. If
you buy Class A shares and exchange into another fund before the 91st day after
the day of purchase, you may not be able to include the sales charge in your
calculation of tax gain or loss on the sale of the first fund you purchased. The
sales charge may be included in the calculation of your tax gain or loss on a
subsequent sale of the second fund you purchased. For more information, see the
SAI.

REITs often do not provide complete tax information until after the
calendar year-end; generally mid to late January and continuing through early
February. Consequently, if your fund has significant investments in REITs, you
may not receive your Form 1099-DIV until February. Other RiverSource funds tax
statements are generally mailed in January.

FOR TAXABLE FUNDS. Distributions related to shares not held in IRAs or other
retirement accounts are subject to federal income tax and may be subject to
state and local taxes in the year they are declared. You must report
distributions on your tax returns, even if they are reinvested in additional
shares.

Shares held in an IRA or qualified retirement account are generally subject to
different tax rules. Taking a distribution from your IRA or qualified retirement
plan may subject you to federal taxes, withholding, penalties and reporting
requirements. Please consult your tax advisor.

Income received by a fund may be subject to foreign tax and withholding. Tax
conventions between certain countries and the U.S. may reduce or eliminate these
taxes.

FOR TAX-EXEMPT FUNDS. Dividends distributed from interest earned on tax-exempt
securities (exempt-interest dividends) are exempt from federal income taxes but
may be subject to state and local taxes and potentially the alternative minimum
tax. Dividends distributed from net capital gains, if any, and other income
earned are not exempt from federal income taxes. Any taxable distributions are
taxable in the year the fund declares them regardless of whether you take them
in cash or reinvest them.

Interest on certain private activity bonds is a preference item for purposes of
the individual and corporate alternative minimum tax. To the extent the fund
earns such income, it will flow through to its shareholders and may affect those
shareholders who are subject to the alternative minimum tax. See the SAI for
more information.

Because interest on municipal bonds and notes is tax-exempt for federal income
tax purposes, any interest on money you borrow that is used directly or
indirectly to purchase fund shares is not deductible on your federal income tax
return. You should consult a tax advisor regarding its deductibility for state
and local income tax purposes.

For a fund organized as a fund-of-funds, because most of the fund's investments
are shares of underlying funds, the tax treatment of the fund's gains, losses,
and distributions may differ from the tax treatment that would apply if either
the fund invested directly in the types of securities held by the underlying
funds or the fund shareholders invested directly in the underlying funds. As a
result, fund shareholders may recognize higher amounts of capital gain
distributions or ordinary income dividends than they otherwise would.

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

General Information

AVAILABILITY AND TRANSFERABILITY OF FUND SHARES

Please consult with your financial intermediary to determine the availability of
the funds. The funds may only be purchased or sold directly or through financial
intermediaries authorized by the distributor to offer the funds. NOT ALL
FINANCIAL INSTITUTIONS ARE AUTHORIZED TO SELL THE RIVERSOURCE FAMILY OF FUNDS
AND CERTAIN FINANCIAL INTERMEDIARIES THAT OFFER THE RIVERSOURCE FAMILY OF FUNDS
MAY NOT OFFER ALL FUNDS ON ALL INVESTMENT PLATFORMS. If you set up an account at
a financial intermediary that does not have, and is unable to obtain, a selling
agreement with the distributor, you will not be able to transfer fund holdings
to that account. In that event, you must either maintain your fund holdings with
your current financial intermediary, find another financial intermediary with a
selling agreement, or sell your shares, paying any applicable CDSC. Please be
aware that transactions in taxable accounts are taxable events and may result in
income tax liability.

ADDITIONAL SERVICES AND COMPENSATION

In addition to acting as the fund's investment manager, RiverSource Investments
and its affiliates also receive compensation for providing other services to the
funds.

ADMINISTRATION SERVICES. Ameriprise Financial, 200 Ameriprise Financial Center,
Minneapolis, Minnesota 55474, provides or compensates others to provide
administrative services to the funds. These services include administrative,
accounting, treasury, and other services. Fees paid by a fund for these services
are included under "Other expenses" in the expense table under "Fees and
Expenses."

DISTRIBUTION AND SHAREHOLDER SERVICES. RiverSource Fund Distributors, Inc.,
50611 Ameriprise Financial Center, Minneapolis, Minnesota 55474, (the
distributor), provides underwriting and distribution services to the funds.
Under the Distribution Agreement and related distribution and shareholder
servicing plans, the distributor receives distribution and shareholder servicing
fees. The distributor may retain a portion of these fees to support its
distribution and shareholder servicing activity. The distributor reallows the
remainder of these fees (or the full fee) to the financial intermediaries that
sell fund shares and provide services to shareholders. Fees paid by a fund for
these services are set forth under "Distribution and/or service (12b-1) fees" in
the expense table under "Fees and Expenses." More information on how these fees
are used is set forth under "Investment Options--Classes of Shares" and in the
SAI. The distributor also administers any sales charges paid by an investor at
the time of purchase or at the time of sale. See "Shareholder Fees (fees paid
directly from your investment)" under "Fees and Expenses" for the scheduled
sales charge of each share class. See "Buying and Selling Shares, Sales Charges"
for variations in the scheduled sales charges, and for how these sales charges
are used by the distributor. See "Other Investment Strategies and Risks" for the
funds' policy regarding directed brokerage.

TRANSFER AGENCY SERVICES. RiverSource Service Corporation, 734 Ameriprise
Financial Center, Minneapolis, Minnesota 55474 (the transfer agent or
RiverSource Service Corporation), provides or compensates others to provide
transfer agency services to the funds. The funds pay the transfer agent a fee
that varies by class, as set forth in the SAI, and reimburses the transfer agent
for its out-of-pocket expenses incurred while providing these transfer agency
services to the funds. Fees paid by a fund for these services are included under
"Other expenses" in the expense table under "Fees and Expenses." RiverSource
Service Corporation pays a portion of these fees to financial intermediaries
that provide sub-recordkeeping and other services to fund

shareholders. The SAI provides additional information about the services
provided and the fee schedules for the transfer agent agreements.

PLAN ADMINISTRATION SERVICES. Under a Plan Administration Services 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. Fees paid by a fund for these services are included under "Other
expenses" in the expense table under "Fees and Expenses."

PAYMENTS TO FINANCIAL INTERMEDIARIES. The distributor and its affiliates make or
support additional cash payments out of their own resources (including profits
earned from providing services to the fund) to financial intermediaries, in
connection with agreements between the distributor and financial intermediaries
pursuant to which these financial intermediaries sell fund shares and provide
services to their clients who are shareholders of the fund. These payments and
intercompany allocations (collectively, "payments") do not change the price paid
by investors in the fund or fund shareholders for the purchase or ownership of
fund shares of the fund, and these payments are not reflected in the fees and
expenses of the fund, as they are not paid by the fund.

In exchange for these payments, a financial intermediary may elevate the
prominence or profile of the fund within the financial intermediary's
organization, and may provide the distributor and its affiliates with preferred
access to the financial intermediary's registered representatives or preferred
access to the financial intermediary's customers. These arrangements are
sometimes referred to as marketing and/or sales support payments, program and/or
shareholder servicing payments, or revenue sharing payments. These arrangements
create potential conflicts of interest between a financial intermediary's
pecuniary interest and its duties to its customers, for example, if the
financial intermediary receives higher payments from the sale of a certain fund
than it receives from the sale of other funds, the financial intermediary or its
representatives may be incented to recommend or sell shares of the fund where
it receives or anticipates receiving the higher payment instead of other
investment options that may be more appropriate for the customer. Employees of
Ameriprise Financial and its affiliates, including employees of affiliated
broker-dealers, may be separately incented to recommend or sell shares of the
fund, as employee compensation and business unit operating goals at all levels
are tied to the company's success. Certain employees, directly or indirectly,
may receive higher compensation and other benefits as investment in the fund
increases. In addition, management, sales leaders and other employees may spend
more of their time and resources promoting Ameriprise Financial and its
subsidiary companies, including RiverSource Investments and the distributor, and
the products they offer, including the fund.

These payments are typically negotiated based on various factors including, but
not limited to, the scope and quality of the services provided by the financial
intermediary, its reputation in the industry, its ability to attract and retain
assets, its access to target markets, its customer relationships, the profile
the fund may obtain within the financial intermediary, and the access the
distributor or other representatives of the fund may have within the financial
intermediary for advertisement, training or education, including opportunities
to present at or sponsor conferences for the registered representatives of the
financial intermediary and its customers.

These payments are usually calculated based on a percentage of fund assets owned
through the financial intermediary and/or as a percentage of fund sales
attributable to the financial intermediary. Certain financial intermediaries
require flat

fees instead of, or in addition to, these asset-based fees as compensation for
including or maintaining a fund on their platforms, and, in certain situations,
may require the reimbursement of ticket or operational charges--fees that a
financial intermediary charges its registered representatives for effecting
transactions in the fund. The amount of payment varies by financial intermediary
(e.g., initial platform set-up fees, ongoing maintenance or service fees, or
asset or sales based fees). The amount of payments also varies by the type of
sale. For instance, purchases of one fund may warrant a greater or lesser amount
of payments than purchases of another fund. Additionally, sale and maintenance
of shares on a stand alone basis may result in a greater or lesser amount of
payments than the sale and maintenance of shares made through a plan, wrap or
other fee-based program. Payments to affiliates may include payments as
compensation to employees of RiverSource Investments who are licensed by the
distributor in respect of certain sales and solicitation activity on behalf of
the fund. These payments may be and often are significant.

Payments to affiliated broker-dealers are within the range of the payments the
distributor pays to similarly-situated third party financial intermediaries and
the payments such affiliated broker-dealers receive from third party fund
sponsors related to the sale of their sponsored funds. However, because of the
large amount of fund assets (from the RiverSource Family of Funds, in aggregate)
currently held in customer accounts of the affiliated broker-dealers, the
distributor and its affiliates, in the aggregate, pay significantly more in
absolute dollars than other third-party fund sponsors pay to the affiliated
broker-dealers for the sale and servicing of their sponsored funds. This level
of payment creates potential conflicts of interest which the affiliated
broker-dealers seek to mitigate by disclosure and implementation of internal
controls, as well as the rules and regulations of applicable regulators.

From time to time, to the extent permitted by SEC and FINRA rules and by other
applicable laws and regulations, the distributor and its affiliates may make
other reimbursements or payments to financial intermediaries or their registered
representatives, including non-cash compensation, in the form of gifts of
nominal value, occasional meals, tickets, or other entertainment, support for
due diligence trips, training and educational meetings or conference
sponsorships, support for recognition programs, and other forms of non-cash
compensation permissible under regulations to which these financial
intermediaries and their representatives are subject. To the extent these are
made as payments instead of reimbursement, they may provide profit to the
financial intermediary to the extent the cost of such services was less than the
actual expense of the service.

The financial intermediary through which you are purchasing or own shares of the
fund has been authorized directly or indirectly by the distributor to sell the
fund and/or to provide services to you as a shareholder of the fund. Investors
and current shareholders may wish to take such payment arrangements into account
when considering and evaluating any recommendations they receive relating to
fund shares. If you have questions regarding the specific details regarding the
payments your financial intermediary may receive from the distributor or its
affiliates related to your purchase or ownership of the fund, please contact
your financial intermediary.

The payments described in this section are in addition to fees paid by the fund
to the distributor under 12b-1 plans, which fees may be used to compensate
financial intermediaries for the distribution of fund shares and the servicing
of fund shareholders, or paid by the fund to the transfer agent under the
transfer agent agreement or plan administration agreement, which fees may be
used to support networking or servicing fees to compensate financial
intermediaries for supporting shareholder account maintenance, sub-accounting,
plan recordkeeping or other serv-

ices provided directly by the financial intermediary to shareholders or plans
and plan participants, including retirement plans, 529 plans, Health Savings
Account plans, or other plans, where participants beneficially own shares of the
fund.

Financial institutions may separately charge you additional fees. See "Buying
and Selling Shares."

ADDITIONAL MANAGEMENT INFORMATION

AFFILIATED PRODUCTS. RiverSource Investments also serves as investment manager
to Seligman funds and RiverSource funds which are structured to provide
asset-allocation services to shareholders of those funds by investing in shares
of other Seligman funds and RiverSource funds, respectively, (Funds of Funds)
and to discretionary managed accounts that invests exclusively in the funds
(collectively referred to as "affiliated products"). These affiliated products,
individually or collectively, may own a significant percentage of the fund's
outstanding shares. The fund may experience relatively large purchases or
redemptions from the affiliated products. Although RiverSource Investments may
seek to minimize the impact of these transactions, for example, by structuring
them over a reasonable period of time or through other measures, the fund may
experience increased expenses as it buys and sells securities to manage
transactions for the affiliated products. In addition, because the affiliated
products may own a substantial portion of the fund, a redemption by one or more
affiliated products could cause the fund's expense ratio to increase as the
fund's fixed costs would be spread over a smaller asset base. RiverSource
Investments monitors expense levels and is committed to offering funds that are
competitively priced. RiverSource Investments reports to the Board on the steps
it has taken to manage any potential conflicts.

CASH RESERVES. A fund may invest its daily cash balance in a money market fund
selected by RiverSource Investments, including but not limited to RiverSource
Short-Term Cash Fund (Short-Term Cash Fund), a money market fund established for
the exclusive use of funds in the RiverSource Family of Funds and other
institutional clients of RiverSource Investments. While Short-Term Cash Fund
does not pay an advisory fee to RiverSource Investments, it does incur other
expenses, and is expected to operate at a very low expense ratio. A fund will
invest in Short-Term Cash Fund or any other money market fund selected by
RiverSource Investments only to the extent it is consistent with the fund's
investment objectives and policies. Short-Term Cash Fund is not insured or
guaranteed by the FDIC or any other government agency.

FUND HOLDINGS DISCLOSURE. The Board has adopted policies and procedures that
govern the timing and circumstances of disclosure to shareholders and third
parties of information regarding the securities owned by a fund. A description
of these policies and procedures is included in the SAI.

Financial Highlights

The tables below are intended to help you understand the financial performance
of the Fund's Classes for the past five years. Certain information reflects
financial results for a single share of a Class that was held throughout the
periods shown. Per share amounts are calculated based on average shares
outstanding. "Total return" shows the rate that you would have earned (or lost)
on an investment in each Class, assuming you reinvested all your dividend
distributions, if any. Total returns do not reflect any sales charges,
transaction costs on your investment or taxes. If such charges, costs or taxes
were reflected, total returns would have been lower. Deloitte & Touche LLP,
Independent Registered Public Accounting Firm, has audited this information.
Their report, along with the Fund's financial statements, is included in the
Fund's Annual Report, which is available upon request. Effective May 18, 2009,
Ernst & Young LLP serves as the Fund's Independent Registered Public Accounting
Firm.

Effective on or about June 13, 2009, the Fund's Class R shares are renamed as
Class R2 shares.

Riversource Family of Funds Privacy Notice

The RiverSource Family of Funds, which includes RiverSource, Seligman, and
Threadneedle, branded funds (collectively, the "funds"), are committed to
respecting shareholders' rights of privacy and we have adopted the following
policy to maintain the confidentiality of the information you share with us:
