*   Effective on or about June 13, 2009, the Class R and Class I shares of the
    Seligman Funds will be redesignated as Class R2 and Class R5 shares,
    respectively. However, for convenience of reference, this combined proxy
    statement/prospectus refers to each class of shares by its designation as of
    the date of this proxy statement/prospectus.

These proposals will be considered by shareholders of the Selling Funds
(including the Seligman Subadvised Funds) at a joint special meeting of such
shareholders (the "Meeting") that will be held at 10:00 a.m. CDT on June 2,
2009, at The Marquette Hotel, 710 Marquette Avenue, Minneapolis, Minnesota 55402
in the Minnesota River Room on the Third floor. Each of the Selling Funds and
the Buying Funds (collectively, the "Funds") is a registered open-end management
investment company (or a series thereof) and is part of the RiverSource Family
of Funds, which includes funds branded "RiverSource," "RiverSource Partners,"
"Threadneedle" and "Seligman." Please read this combined proxy
statement/prospectus and keep it for future reference.

The Board of Directors/Trustees of each Selling Fund (including the Seligman
Subadvised Funds) (the "Board" or the "Board of Directors/Trustees") has
reviewed these proposals and recommends that you approve them.


                                        3





Although the Board of each Selling Fund recommends that shareholders approve the
reorganization of each Selling Fund with the corresponding Buying Fund (each a
"Reorganization"), the Reorganization of each Selling Fund is not conditioned
upon the Reorganization of any other Selling Fund (or upon approval of the
Manager of Managers Proposal by any Seligman Subadvised Fund). Accordingly, if
shareholders of one Selling Fund approve its Reorganization, but shareholders of
another Selling Fund do not approve that Selling Fund's Reorganization, it is
expected that the Reorganization of the first Selling Fund will take place as
described in this combined proxy statement/prospectus.

Similarly, although the Board recommends that shareholders of each Seligman
Subadvised Fund approve the Manager of Managers Proposal, each Manager of
Managers Proposal is not conditioned upon the approval of the Manager of
Managers Proposal for any other Seligman Subadvised Fund (or upon approval of
the Reorganization of the Seligman Subadvised Fund).

HOW EACH REORGANIZATION WILL WORK

- - Each Selling Fund will transfer all of its assets to the corresponding Buying
  Fund in exchange for shares of the corresponding Buying Fund ("Reorganization
  Shares") and the assumption by the corresponding Buying Fund of all of the
  Selling Fund's liabilities.

- - Each Buying Fund will issue Reorganization Shares with an aggregate net asset
  value equal to the aggregate value of the assets that it receives from the
  corresponding Selling Fund, less the liabilities it assumes from the
  corresponding Selling Fund. The Reorganization Shares of each class of each
  Buying Fund will be distributed to the shareholders of the corresponding class
  of the corresponding Selling Fund in proportion to their holdings of such
  class of such Selling Fund. For example, holders of Class A shares of a
  Selling Fund will receive Class A shares of the corresponding Buying Fund with
  the same aggregate net asset value as the aggregate net asset value of the
  corresponding Selling Fund Class A shares at the time of the Reorganization.
  You will not pay any sales charge in connection with this distribution of
  Reorganization Shares. If you already have a Buying Fund account with the
  exact registration as the Selling Fund account, shares distributed in the
  Reorganization are typically added to that account. As a result, when average
  cost is calculated for federal income tax purposes, the cost of the shares in
  the two accounts you owned will be combined.

SECTION A -- REORGANIZATION PROPOSALS

The following information describes each proposed Reorganization.

SUMMARY

This combined proxy statement/prospectus is being used by each Selling Fund to
solicit proxies to vote at a joint special meeting of shareholders. Shareholders
of each Selling Fund will consider a proposal to approve the Agreement and Plan
of Reorganization (the "Agreement") providing for the Reorganization of their
Selling Fund into the corresponding Buying Fund. The form of the Agreement is
attached as Exhibit A.

The following is a summary. More complete information appears later in this
proxy statement/prospectus. You should read the entire combined proxy
statement/prospectus and the exhibits because they contain details that are not
included in the summary.

HOW EACH REORGANIZATION WILL WORK

- - Each Selling Fund will transfer all of its assets to the corresponding Buying
  Fund in exchange for shares of the corresponding Buying Fund ("Reorganization
  Shares") and the assumption by the corresponding Buying Fund of all of the
  Selling Fund's liabilities.

- - Each Buying Fund will issue Reorganization Shares with an aggregate net asset
  value equal to the aggregate value of the assets that it receives from the
  corresponding Selling Fund, less the liabilities it assumes from the
  corresponding Selling Fund. The Reorganization Shares of each class of each
  Buying Fund will be distributed to the shareholders of the corresponding class
  of the corresponding Selling Fund in proportion to their holdings of such
  class of such Selling Fund. For example, holders of Class A shares of a
  Selling Fund will receive Class A shares of the corresponding Buying Fund with
  the same aggregate net asset value as the aggregate net asset value of the
  corresponding Selling Fund Class A shares at the time of the Reorganization.
  If you already have a Buying Fund account with the exact registration as the
  Selling Fund account, shares distributed in the Reorganization are typically
  added to that account. As a result, when average cost is calculated for
  federal income tax purposes, the cost of the shares in the two accounts you
  owned will be combined.

- - As part of the Reorganization, systematic transactions (such as bank
  authorizations and systematic payouts) currently set up for your Selling Fund
  account may be transferred to your new Buying Fund account. Please contact
  your financial institution for additional details.

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

- - After a Reorganization is completed, Selling Fund shareholders will be
  shareholders of the corresponding Buying Fund, and the Selling Fund will be
  dissolved.

TAX CONSEQUENCES

Each Reorganization is expected to be tax-free for federal income tax purposes
and will not take place unless the Selling Fund and the corresponding Buying
Fund receive a satisfactory opinion of tax counsel substantially to that effect.
Accordingly, no gain or loss is expected to be recognized by the Selling Fund or
its shareholders as a direct result of a Reorganization. Some or all of the
portfolio assets of a Selling Fund may be sold in connection with its
Reorganization. The actual tax impact of such sales will depend on the
difference between the price at which such portfolio assets are sold and the
Selling Fund's tax basis in such assets. Any net capital gains recognized in
these sales will be distributed to shareholders as capital-gain dividends (to
the extent of net realized long-term capital gains over net realized short-term
capital losses) and/or ordinary dividends (to the extent of net realized short-
term capital gains over net realized long-term capital losses) during or with
respect to the year of sale, and such distributions will be taxable to
shareholders. Additionally, because each Reorganization will end the tax year of
the applicable Selling Fund, it will accelerate distributions to shareholders
from the Selling Fund for its short tax year ending on the date of the
Reorganization. Those tax year-end distributions will be taxable and will
include any capital gains resulting from portfolio turnover prior to the
Reorganization that were not previously distributed. At any time prior to a
Reorganization, a shareholder may redeem shares of a Selling Fund. This would
likely result in the recognition of gain or loss to the shareholder for federal
income tax purposes if the shareholder holds the shares in a taxable account.

The tax basis and holding period of the shareholders' Selling Fund shares are
expected to carry over to the shareholders' Reorganization Shares in the Buying
Fund.

For more information about the federal income tax consequences of the
Reorganizations, see the section entitled "Tax Status of the Reorganizations."

FEES AND EXPENSES

The following tables describe the fees and expenses that you pay if you buy and
hold shares of a Selling Fund or shares of a Buying Fund. The tables also show
pro forma fees and expenses of each Buying Fund assuming the proposed
Reorganization relating to such Buying Fund had been effective at the beginning
of the most recent fiscal year. The tables reflect adjustments to fees and
expenses that were approved by the Board Jan. 8, 2009, a summary of which is
included in Exhibit C. The expenses shown in the tables do not include any one
time costs, including any expenses related to the Reorganizations that may be
borne by the Funds. See "Reasons for the Proposed Reorganizations and Board
Deliberations" for more information.

The tables have not been adjusted based on current net assets of the Funds,
which will vary throughout the year and from year to year. In general, the
annual operating expenses of a Fund will increase as the Fund's assets decrease.
Due to recent unprecedented market volatility, the current total annual fund
operating expenses listed for the Funds in the tables may be higher than the
expense information presented, which are as of the most recent fiscal year. To
the extent the investment manager and its affiliates have agreed to waive fees
or cap (reimburse) expenses, the impact of the market volatility on the total
annual (net) operating expenses in the current fiscal year will be limited.

    in the RiverSource Family of Funds. See Exhibit B "Sales Charges."
(c) A 1% contingent deferred sales charge ("CDSC") may be assessed on Class A
    shares purchased without an initial sales charge and sold within 18 months
    after purchase. See Exhibit B "Sales Charges."
(d) Effective on or about June 13, 2009, the 1% CDSC will be eliminated on Class

(a) Through at least Jan. 31, 2010, RiverSource Investments has contractually
    agreed to waive its management fee and/or to reimburse Seligman Core Fixed
    Income Fund's expenses to the extent that the Fund's "other expenses" (i.e.,
    those expenses other than management fees, 12b-1 fees, interest on
    borrowings, and extraordinary expenses, including litigation expenses)
    exceed 0.50% per annum of the Fund's average daily net assets.
(b) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5, and a new transfer agent agreement
    and a new plan administration services agreement (Class R2 only) will be in
    effect with new fee structures. Other expenses include the transfer agency
    fee, custody fee, other nonadvisory expenses and a plan administrative
    services fee (Class R2 only).
(c) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses, and a plan administration
    services fee (for Class R2), and have been adjusted to reflect the impact of
    a new per account transfer agency fee (Class A, Class B and Class C direct
    at fund accounts only), effective on or about June 13, 2009. Other expenses
    may also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired fund fees and expenses for the
    most recent fiscal period was less than 0.01%. Because acquired funds will
    have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.
(d) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Aug. 31, 2009, unless
    sooner terminated at the discretion of the RiverSource Diversified Bond
    Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under
    this agreement, net fund expenses (excluding fees and expenses of acquired
    funds), will not exceed 0.83% for Class A, 1.59% for Class B, 1.58% for
    Class C, 1.27% for Class R2 and 0.52% for Class R5.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those periods
both under the current arrangements and, for the Buying Fund, assuming the
proposed Reorganization had been in effect. These examples also assume that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

(a) Through at least Feb. 28, 2010, RiverSource Investments has contractually
    agreed to waive its management fee and/or to reimburse Seligman Emerging
    Market Fund's expenses to the extent that the Fund's "other expenses" (i.e.,
    those expenses other than management fees, 12b-1 fees, interest on
    borrowings, and extraordinary expenses, including litigation expenses)
    exceed 0.85% per annum of the Fund's average daily net assets.
(b) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5 and a new transfer agent agreement and
    a new plan administration services agreement (Class R2 only) will be in
    effect with new fee structures. Other expenses include the transfer agency
    fee, custody fee, other nonadvisory expenses and a plan administrative
    services fee (Class R2 only). Other expenses may also include fees and
    expenses of affiliated and unaffiliated funds (acquired funds) which the
    Fund indirectly bears when it invests in the acquired funds. The impact of
    these acquired fund fees and expenses for the most recent fiscal period was
    less than 0.01%. Because acquired funds will have varied expense and fee
    levels and the Fund may own different proportions of acquired funds at
    different times, the amount of fees and expenses incurred by the Fund with
    respect to such investments will vary.


                                       13






(c) Includes the impact of a performance incentive adjustment fee that increased
    the management fee by 0.08% for the most recent fiscal year. The adjustment
    is computed by measuring the percentage differences over a rolling 12-month
    period between the performance of the Fund and the performance of an index
    of comparable funds published by Lipper Inc. The index against which the
    Threadneedle Emerging Market Fund's performance is measured for purposes of
    determining the performance incentive adjustment is the Lipper Emerging
    Markets Funds Index. In certain circumstances, the Fund's Board may approve
    a change in the index. The maximum adjustment (increase or decrease) is
    0.12% of the Fund's average net assets on an annual basis. See Fund
    Management and Compensation in Exhibit B for more information. Additional
    information on the calculation methodology is set forth in the
    Reorganization SAI.
(d) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses and a plan administration
    services fee (for Class R2), and have been adjusted to reflect the impact of
    a new per account transfer agency fee (Class A, Class B and Class C direct
    at fund accounts only), effective on or about June 13, 2009. Other expenses
    may also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired fund fees and expenses for the
    most recent fiscal period was less than 0.01%. Because acquired funds will
    have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.
    Other expenses for Class R2 are based on estimated amounts for the current
    fiscal year.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those periods
both under the current arrangements and, for the Buying Fund, assuming the
proposed Reorganization had been in effect. These examples also assume that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

(a) Through at least Feb. 28, 2010, RiverSource Investments has contractually
    agreed to waive its management fee and/or to reimburse Seligman Global
    Growth Fund's expenses to the extent that the Fund's "other expenses" (i.e.,
    those expenses other than management fees, 12b-1 fees, interest on
    borrowings, and extraordinary expenses, including litigation expenses)
    exceed 0.85% per annum of the Fund's average daily net assets.
(b) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5, and a new transfer agent agreement
    and a new plan administration services agreement (Class R2 only) will be in
    effect with new fee structures. Other expenses include the transfer agency
    fee, custody fee, other nonadvisory expenses and a plan administrative
    services fee (Class R2 only).
(c) Includes the impact of a performance incentive adjustment fee that increased
    the management fee by 0.06% for the most recent fiscal year. The adjustment
    is computed by measuring the percentage differences over a rolling 12-month
    period between the performance of the Fund and the performance of an index
    of comparable funds published by Lipper Inc. The index against which the
    Threadneedle Global Equity Fund's performance is measured for purposes of
    determining the performance incentive adjustment is the Lipper Global Funds
    Index. In certain circumstances, the Fund's Board may approve a change in
    the index. The maximum adjustment (increase or

                                       15





    decrease) is 0.12% of the Fund's average net assets on an annual basis. See
    Fund Management and Compensation in Exhibit B for more information.
    Additional information on the calculation methodology is set forth in the
    Reorganization SAI.
(d) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses, and a plan administration
    services fee (for Class R2), and have been adjusted to reflect the impact of
    a new per account transfer agency fee (Class A, Class B, and Class C direct
    at fund accounts only), effective on or about June 13, 2009. Other expenses
    may also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired fund fees and expenses for the
    most recent fiscal period was less than 0.01%. Because acquired funds will
    have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those periods
both under the current arrangements and, for the Buying Fund, assuming the
proposed Reorganization had been in effect. These examples also assume that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

(a) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5, and a new transfer agent agreement
    and a new plan administration services agreement (Class R2 only) will be in
    effect with new fee structures. Other expenses include the transfer agency
    fee, custody fee, other nonadvisory expenses and a plan administrative
    services fee (Class R2 only). Other expenses may also include fees and
    expenses of affiliated and unaffiliated funds (acquired funds) which the
    Fund indirectly bears when it invests in the acquired funds. The impact of
    these acquired fund fees and expenses for the most recent fiscal period was
    less

    than 0.01%. Because acquired funds will have varied expense and fee levels
    and the Fund may own different proportions of acquired funds at different
    times, the amount of fees and expenses incurred by the Fund with respect to
    such investments will vary.
(b) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses, and a plan administration
    services fee (for Class R2), and have been adjusted to reflect the impact of
    a new per account transfer agency fee (Class A, Class B, and Class C direct
    at fund accounts only), effective on or about June 13, 2009. Other expenses
    may also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired fund fees and expenses for the
    most recent fiscal period was less than 0.01%. Because acquired funds will
    have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until May 31, 2009, unless
    sooner terminated at the discretion of the RiverSource High Yield Bond
    Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under
    this agreement, net fund expenses (excluding fees and expenses of acquired
    funds), will not exceed 1.02% for Class A, 1.78% for Class B, 1.77% for
    Class C, 1.45% for Class R2 and 0.70% for Class R5.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those periods
both under the current arrangements and, for the Buying Fund, assuming the
proposed Reorganization had been in effect. These examples also assume that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

(a) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5, and a new transfer agent agreement
    and a new plan administration services agreement (Class R2 only) will be in
    effect with new fee structures. Other expenses include the transfer agency
    fee, custody fee, other nonadvisory expenses and a plan administrative
    services fee (Class R2 only). Other expenses may also include fees and
    expenses of affiliated and unaffiliated funds (acquired funds) which the
    Fund indirectly bears when it invests in the acquired funds. The impact of
    these acquired fund fees and expenses for the most recent fiscal period was
    less than 0.01%. Because acquired funds will have varied expense and fee
    levels and the Fund may own different proportions of acquired funds at
    different times, the amount of fees and expenses incurred by the Fund with
    respect to such investments will vary.
(b) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.09% for the most recent fiscal year. The adjustment
    is computed by measuring the percentage differences over a rolling 12-month
    period between the performance of the Fund and the performance of an index
    of comparable funds published by Lipper Inc. The index against which the
    RiverSource Balanced Fund's performance is measured for purposes of
    determining the performance incentive adjustment is the Lipper Balanced
    Funds Index. In certain circumstances, the Fund's Board may approve a change
    in the index. The maximum adjustment (increase or decrease) is 0.08% of the
    Fund's average net assets on an annual basis. See Fund Management and
    Compensation in Exhibit B for more information. Additional information on
    the calculation methodology is set forth in the Reorganization SAI.


                                       19






(c) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses, and a plan administration
    services fee (for Class R2), and have been adjusted to reflect the impact of
    a new per account transfer agency fee (Class A, Class B, and Class C direct
    at fund accounts only), effective on or about June 13, 2009. Other expenses
    may also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired fund fees and expenses for the
    most recent fiscal period was less than 0.01%. Because acquired funds will
    have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.
    Other expenses for Class R2 and Class R5 are based on estimated amounts for
    the current fiscal year.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those periods
both under the current arrangements and, for the Buying Fund, assuming the
proposed Reorganization had been in effect. These examples also assume that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

(a) Through at least Feb 28, 2010, RiverSource Investments has contractually
    agreed to waive its management fee and/or to reimburse Seligman
    International Growth Fund's expenses to the extent that the Fund's "other
    expenses" (i.e., those expenses other than management fees, 12b-1 fees,
    interest on borrowings, and extraordinary expenses, including litigation
    expenses) exceed 0.85% per annum of the Fund's average daily net assets.
(b) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5, and a new transfer agent agreement
    and a new plan administration services agreement (Class R2 only) will be in
    effect with new fee structures. Other expenses include the transfer agency
    fee, custody fee, other nonadvisory expenses and a plan administrative
    services fee (Class R2 only).
(c) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.06% for the most recent fiscal year. The adjustment
    is computed by measuring the percentage differences over a rolling 12-month
    period between the performance of the Fund and the performance of an index
    of comparable funds published by Lipper Inc. The index against which the
    RiverSource Partners International Select Growth Fund's performance is
    measured for purposes of determining the performance incentive adjustment is
    the Lipper International Multi-Cap Growth Funds Index. In certain
    circumstances, the Fund's Board may approve a change in the index. The
    maximum adjustment (increase or decrease) is 0.12% of the Fund's average net
    assets on an annual basis. See Fund Management and Compensation in Exhibit B
    for more information. Additional information on the calculation methodology
    is set forth in the Reorganization SAI.
(d) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses, and a plan administration
    services fee (for Class R2), and have been adjusted to reflect the impact of
    a new per account transfer agency fee (Class A, Class B, and Class C direct
    at fund accounts only), effective on or about June 13, 2009. Other expenses
    may also include fees and expenses of affiliated and unaffiliated funds
    (acquired funds) which the Fund indirectly bears when it invests in the
    acquired funds. The impact of these acquired fund fees and expenses for the
    most recent fiscal period was less than 0.01%. Because acquired funds will
    have varied expense and fee levels and the Fund may own different
    proportions of acquired funds at different times, the amount of fees and
    expenses incurred by the Fund with respect to such investments will vary.
    Other expenses for Class R2 and Class R5 are based on estimated amounts for
    the current fiscal year.
(e) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Oct. 31, 2009, unless
    sooner terminated at the discretion of the RiverSource Partners
    International Select Growth Fund's Board. Any amounts waived will not be
    reimbursed by the Fund. Under this agreement, net fund expenses (excluding
    fees and expenses of acquired funds), before giving effect to any
    performance incentive adjustment, will not exceed 1.44% for Class A, 2.21%
    for Class B, 2.20% for Class C, 1.80% for Class R2 and 1.05% for Class R5.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those periods
both under the current arrangements and, for the Buying Fund, assuming the
proposed Reorganization had been in effect. These examples also assume that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

(a) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5, and a new transfer agent agreement
    and a new plan administration services agreement (Class R2 only) will be in
    effect with new fee structures. Other expenses include the transfer agency
    fee, custody fee, other nonadvisory expenses and a plan administrative
    services fee (Class R2 only).
(b) Other expenses include an administrative services fee, a transfer agency
    fee, a custody fee, other nonadvisory expenses, and a plan administration
    services fee (for Class R2), and have been adjusted to reflect the impact of
    a new per account transfer agency fee (Class A, Class B, and Class C direct
    at fund accounts only), effective

                                       24





    on or about June 13, 2009. Other expenses may also include fees and expenses
    of affiliated and unaffiliated funds (acquired funds) which the Fund
    indirectly bears when it invests in the acquired funds. The impact of these
    acquired fund fees and expenses for the most recent fiscal period was less
    than 0.01%. Because acquired funds will have varied expense and fee levels
    and the Fund may own different proportions of acquired funds at different
    times, the amount of fees and expenses incurred by the Fund with respect to
    such investments will vary. Other expenses for Class R2 are based on
    estimated amounts for the current fiscal year.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until May 31, 2009, unless
    sooner terminated at the discretion of the RiverSource Short Duration U.S.
    Government Fund's Board. Any amounts waived will not be reimbursed by the
    Fund. Under this agreement, net fund expenses (excluding fees and expenses
    of acquired funds), will not exceed 0.89% for Class A, 1.65% for Class B,
    1.65% for Class C and 1.31% for Class R2.

EXPENSE EXAMPLES: These examples are intended to help you compare the cost of
investing in the Funds with the cost of investing in other mutual funds. These
examples assume that you invest $10,000 in the applicable Fund for the time
periods indicated and then redeem all of your shares at the end of those periods
both under the current arrangements and, for the Buying Fund, assuming the
proposed Reorganization had been in effect. These examples also assume that your
investment has a 5% return each year and that the Fund's operating expenses
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

PROPOSAL 1. REORGANIZATION OF SELIGMAN CORE FIXED INCOME FUND INTO RIVERSOURCE
DIVERSIFIED BOND FUND

COMPARISON OF INVESTMENT OBJECTIVES

Each Fund seeks a high level of current income consistent with prudent exposure
to risk or conservation of investment value. Seligman Core Fixed Income Fund
also seeks capital appreciation as a secondary objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman Core Fixed Income Fund seeks to produce a high
                        level of current income consistent with prudent exposure
                        to risk. Capital appreciation is a secondary objective.

          BUYING FUND: RiverSource Diversified Bond Fund seeks to provide
                       shareholders with a high level of current income while
                       conserving the value of the investment for the longest
                       period of time.

Because any investment involves risk, there is no assurance the Fund's objective
can be achieved. Only shareholders can change the Fund's objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests predominantly in U.S. dollar-denominated fixed-income
securities of U.S. issuers. Under normal market conditions, the Selling Fund
intends to maintain at least 70% of its net assets in investment grade fixed-
income securities and may invest up to 30% of its net assets in non-investment
grade, high yield securities. The Buying Fund invests at least 50% of its assets
in securities like those in its benchmark index (the Barclays Capital U.S.
Aggregate Bond Index), which are exclusively investment grade securities, and
may therefore invest up to 50% of its assets in non-investment grade securities.
The Selling Fund may invest up to 20% of its net assets in non-U.S. dollar-
denominated fixed-income securities of U.S. or foreign issuers. The Buying Fund
may invest up to 25% of its net assets in foreign investments. The Buying Fund
targets an average portfolio duration within one year of that of its benchmark
index but is not restricted with regards to duration. The Selling Fund, which
may invest in securities of any duration, is currently targeting the same
average portfolio duration as the Buying Fund. The Selling Fund does not have
any portfolio maturation limitations on its investments and, therefore, may
invest in securities with short, medium or long maturities. The Selling Fund and
the Buying Fund seek to maintain an effective dollar-weighted average maturity
of ten years or less on their portfolios of fixed-income securities but are not
restricted to such limit.

DETAILED STRATEGIES FOR THE SELLING FUND AND THE BUYING FUND ARE SET FORTH
BELOW:

SELIGMAN CORE FIXED INCOME FUND (SELLING FUND)

The Fund will invest at least 80% of its net assets in fixed-income securities.
Under normal market conditions, the Fund intends to maintain at least 70% of its
net assets in investment grade fixed-income securities ("Investment Grade
Securities") and may invest up to 30% of its net assets in non-investment grade,
high yield securities ("High Yield Securities"). The proportion of the Fund's
assets invested in each type of security will vary from time to time based on
the investment manager's assessment of general market and economic conditions.

The Fund may invest in securities of any duration. The Fund does not have any
portfolio maturation limitations on its investments and, therefore, may invest
in securities with short, medium or long maturities. However, the Fund expects
to maintain an effective dollar-weighted average maturity of ten years or less
on its portfolio of fixed-income securities. Although the Fund expects the
maturity of its portfolio of fixed-income securities to be within the above
limit, the Fund is not restricted to such limit.

The Fund will invest its net assets primarily in U.S. dollar-denominated fixed-
income securities of U.S. issuers. However, the Fund may also invest in U.S.
dollar-denominated fixed-income securities of foreign issuers, including foreign
governments or their agencies or instrumentalities, foreign banks and foreign
corporations. The Fund may also invest up to 20% of its net assets in non-U.S.
dollar-denominated fixed-income securities of U.S. or foreign issuers.

The Fund's investment limitations and credit ratings restrictions (e.g., those
of Fitch Ratings ("Fitch"), Moody's Investors Service ("Moody's") and Standard &
Poor's Ratings Services ("S&P")) will apply at the time securities are
purchased. The Fund is not required to sell a security if it no longer complies
with these limitations or restrictions as a result of a change in rating or
other event.

INVESTMENT GRADE SECURITIES

Investment Grade Securities are those rated within the four highest rating
categories by Moody's or S&P, or, if unrated, deemed by the Fund's investment
manager to be of comparable quality.


                                       26





HIGH-YIELD SECURITIES

High-Yield Securities (many of which are commonly known as "junk bonds") carry
noninvestment grade ratings (Ba or below by Moody's or BB or below by Fitch or
S&P) or are securities deemed to be below investment grade by the Fund's
investment manager. Although High-Yield Securities have the potential to offer
higher yields than higher rated fixed-income securities with similar maturities,
High-Yield Securities are subject to greater risk of loss of principal and
interest than higher rated Investment Grade Securities.

INVESTMENTS IN INVESTMENT GRADE SECURITIES AND HIGH-YIELD SECURITIES

The Fund may invest in all types of Investment Grade Securities and High Yield
Securities, including, but not limited to:

- - Senior and subordinated corporate debt obligations of both U.S. and non-U.S.
  issuers (including, for example, debentures, loan participations and floating
  rate notes);

- - Mortgage-backed and other asset-backed securities (mortgage backed securities
  include collateralized mortgage obligations, mortgage pass-through securities
  and stripped mortgage backed securities);

- - Convertible securities, preferred stock, capital securities, structured
  securities and loan participations of U.S. and non-U.S. issuers;

- - Obligations of non-U.S. governments and their agencies, and non-U.S. private
  institutions;

- - Municipal securities;

- - Repurchase agreements;

- - Capital appreciation bonds, including zero coupon (interest payments accrue
  until maturity) and pay-in-kind securities (interest payments are made in
  additional securities);

- - Restricted securities that may be offered and sold only to "qualified
  institutional buyers" under Rule 144A of the Securities Act of 1933 ("Rule
  144A Securities"); and

- - Eurodollar bonds.

Investment Grade Securities also include, but are not limited to:

- - Obligations issued or guaranteed by the U.S. government or its agencies or
  instrumentalities;

- - Obligations of government sponsored enterprises (e.g., the Federal Home Loan
  Mortgage Corporation (Freddie Mac) and the Federal National Mortgage
  Association (Fannie Mae));

- - Income-producing cash equivalents (e.g., certificates of deposit, commercial
  paper, discount notes and treasury bills); and

- - Other securities deemed by the investment manager to be of investment grade
  quality.

High Yield Securities also include, but are not limited to:

- - Securities that are rated in default by a nationally recognized statistical
  rating organization;

- - Warrants, rights and other equity securities that are acquired in connection
  with the Fund's investments in High Yield Securities; and

- - Other securities deemed by the investment manager to be of non-investment
  grade quality.

INVESTMENT PROCESS

Investment Grade Securities. In pursuit of the Fund's objective, the investment
manager chooses Investment Grade Securities by:

- - Evaluating the Investment Grade Securities portion of the portfolio's exposure
  to sectors, industries and securities relative to the Barclays Capital U.S.
  Aggregate Bond Index (the "Index").

- - Analyzing factors such as credit quality, interest rate outlook and price in
  seeking to select the most attractive securities within each sector.

- - Targeting an average portfolio duration within one year of the duration of the
  Index which, as of Jan. 31, 2009, was 4.18 years.

In evaluating whether to sell an Investment Grade Security, the investment
manager considers, among other factors:

- - Identification of more attractive investments based on relative value.

- - The portfolio's total exposure to sectors, industries and securities relative
  to the Index.

- - Whether a security's rating has changed or is vulnerable to a change.


                                       27





- - Whether a sector or industry is experiencing change.

- - Changes in the interest rate or economic outlook.

High Yield Securities. In pursuit of the Fund's objective, the investment
manager chooses High Yield Securities by:

- - Reviewing interest rate and economic forecasts.

- - Reviewing credit characteristics and capital structures of companies,
  including an evaluation of any outstanding bank loans or corporate debt
  securities a company has issued, its relative position in its industry, and
  its management team's capabilities.

- - Identifying companies that:

  - have medium and low quality ratings or, in the investment manager's opinion,
    have similar qualities to companies with medium or low quality ratings, even
    though they are not rated, or have been given a different rating by a rating
    agency,

  - have growth potential, or

  - have the potential to increase in value as their credit ratings improve.

- - Buying debt instruments that are expected to outperform other debt
  instruments.

In evaluating whether to sell High Yield Securities, the investment manager
considers, among other factors, whether:

- - The interest rate or economic outlook changes.

- - A sector or industry is experiencing change.

- - A security's rating is changed.

- - The security is overvalued relative to alternative investments.

- - The company no longer meets the investment manager's performance expectations.

- - The investment manager wishes to lock in profits.

- - 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 up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold within seven days at approximately the
Fund's value of the securities) including funding agreements issued by domestic
insurance companies. Rule 144A Securities deemed to be liquid by the Fund's
investment manager are not included in this limitation. The Fund may purchase
securities on a when issued or forward commitment basis (delivery of securities
and payment of the purchase price takes place after the commitment to purchase
the securities).

RIVERSOURCE DIVERSIFIED BOND FUND (BUYING FUND)

Under normal market conditions, the Fund invests at least 80% of its net assets
in bonds and other debt securities. At least 50% of the Fund's net assets will
be invested in securities like those included in the Barclays Capital U.S.
Aggregate Bond Index (the "Index"), which are investment grade and denominated
in U.S. dollars. The Index includes securities issued by the U.S. government,
corporate bonds, and mortgage- and asset-backed securities. Although the Fund
emphasizes high- and medium-quality debt securities, it will assume some credit
risk in an effort to achieve higher yield and/or capital appreciation by buying
lower-quality (junk) bonds. Up to 25% of the Fund's net assets may be invested
in foreign investments, which may include investments in emerging markets. The
Fund will provide shareholders with at least 60 days' notice of any change in
the 80% policy.

The selection of debt obligations is the primary decision in building the
investment portfolio. In pursuit of the Fund's objective, the investment manager
chooses investments by:

- - Evaluating the portfolio's total exposure to sectors, industries and
  securities relative to the Index.

- - Analyzing factors such as credit quality, interest rate outlook and price in
  seeking to select the most attractive securities within each sector.

- - Investing in lower-quality (junk) bonds and foreign investments as attractive
  opportunities arise.

- - Targeting an average portfolio duration within one year of the duration of the
  Index which, as of Jan. 31, 2009, was 4.18 years. Duration measures the
  sensitivity of bond prices to changes in interest rates. The longer the
  duration of a bond, the longer it will take to repay the principal and
  interest obligations and the more sensitive it will be to changes in interest
  rates. For example, a five-year duration means a bond is expected to decrease
  in value by 5% if interest rates rise 1% and increase in value by 5% if
  interest rates fall 1%.

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

- - Identification of more attractive investments based on relative value.

- - The portfolio's total exposure to sectors, industries and securities relative
  to the Index.

- - Whether a security's rating has changed or is vulnerable to a change.

- - Whether a sector or industry is experiencing change.

- - Changes in the interest rate or economic outlook.

The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, in an effort to produce
incremental earnings, to hedge existing positions, to increase market exposure
and investment flexibility, or to obtain or reduce credit exposure.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

For purposes of this discussion, a "fundamental" investment policy is one that
may not be changed without a shareholder vote. The Funds' fundamental investment
policies are set forth below:

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives, principal investment strategies and
investment policies. With regards to investment policies, the Buying Fund may
expose shareholders to greater credit risk and liquidity risk due to the Buying
Fund's greater ability to invest in, and greater current exposure to, high yield
(junk) bonds. Also, the Buying Fund may expose shareholders to greater foreign
risk due to the Buying Fund's greater ability to invest in foreign securities.
The actual risks of investing in each Fund depend on the securities held in each
Fund's portfolio and on market conditions, both of which change over time. Both
Funds are subject to the principal investment risks described below.

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

- - CREDIT RISK. Credit risk is the risk that the issuer of a security, or the
  counterparty to a contract, will default or otherwise become unable or
  unwilling to honor a financial obligation, such as payments due on a bond or a
  note. If the Fund purchases unrated securities, or if the rating of a security
  is reduced after purchase, the Fund will depend on the investment manager's
  analysis of credit risk more heavily than usual. Non-investment grade
  securities, commonly called high yield or junk bonds, may react more to
  perceived changes in the ability of the issuing entity to pay interest and
  principal when due than to changes in interest rates. Non-investment grade
  securities have greater price fluctuations and are more likely to experience a
  default than investment grade bonds.

- - RISKS OF FOREIGN INVESTING. Foreign securities are securities of issuers based
  outside the United States. An issuer is deemed to be based outside the United
  States if it is organized under the laws of another country. Foreign
  securities are primarily denominated in foreign currencies. In addition to the
  risks normally associated with domestic securities of the same type, foreign
  securities are subject to the following foreign risks:

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

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

 Custody risk refers to the process of clearing and settling trades. It also
 covers holding securities with local agents and depositories. Low trading
 volumes and volatile prices in less developed markets make trades harder to
 complete and settle. Local agents are held only to the standard of care of the
 local market. Governments or trade groups may compel local agents to hold
 securities in designated depositories that are not subject to independent
 evaluation. The less developed a country's securities market is, the greater
 the likelihood of problems occurring.

 Emerging markets risk includes the dramatic pace of change (economic, social
 and political) in these countries as well as the other considerations listed
 above. These markets are in early stages of development and are extremely
 volatile. They can be marked by extreme inflation, devaluation of currencies,
 dependence on trade partners and hostile relations with neighboring countries.

- - INTEREST RATE RISK. Interest rate risk is the risk of losses attributable to
  changes in interest rates. Interest rate risk is generally associated with
  bond prices: when interest rates rise, bond prices fall. In general, the
  longer the maturity or duration of a bond, the greater its sensitivity to
  changes in interest rates.

- - LIQUIDITY RISK. The risk associated from a lack of marketability of securities
  which may make it difficult or impossible to sell at desirable prices in order
  to minimize loss. The Fund may have to lower the selling price, sell other
  investments, or forego another, more appealing investment opportunity.

- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably.

- - PREPAYMENT AND EXTENSION RISK. Prepayment and extension risk is the risk that
  a bond or other security might be called or otherwise converted, prepaid, or
  redeemed before maturity. This risk is primarily associated with asset-backed
  securities, including mortgage-backed securities. If a security is converted,
  prepaid, or redeemed before maturity, particularly during a time of declining
  interest rates, the investment manager may not be able to reinvest in
  securities providing as high a level of income, resulting in a reduced yield
  to the Fund. Conversely, as interest rates rise, the likelihood of prepayment
  decreases. The investment manager may be unable to capitalize on securities
  with higher interest rates because the Fund's investments are locked in at a
  lower rate for a longer period of time.

In addition to the risks described above, the Buying Fund is subject to the
additional principal investment risk set forth below. While this additional risk
may also be a risk of the Selling Fund, it is not stated as a principal
investment risk of the Selling Fund. For more information regarding the Selling
Fund's principal investment risks, see "Principal Risks" in the Selling Fund's
prospectus.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  counterparty credit risk, hedging risk, correlation risk, liquidity risk and
  leverage risk.

 Counterparty credit risk is the risk that a counterparty to the derivative
 instrument becomes bankrupt or otherwise fails to perform its obligations due
 to financial difficulties, and the Fund may obtain no recovery of its
 investment or may only obtain a limited recovery, and any recovery may be
 delayed.

 Hedging Risk is the risk that derivative instruments used to hedge against an
 opposite position, may offset losses, but they may also offset gains.

 Correlation Risk is related to hedging risk and is the risk that there may be
 an incomplete correlation between the hedge and the opposite position, which
 may result in increased or unanticipated losses.

 Liquidity Risk is the risk that the derivative instrument may be difficult or
 impossible to sell or terminate, which may cause the Fund to be in a position
 to do something the investment manager would not otherwise choose, including
 accepting a lower price for the derivative instrument, selling other
 investments or foregoing another, more appealing investment opportunity.

 Leverage Risk is the risk that losses from the derivative instrument may be
 greater than the amount invested in the derivative instrument. Certain
 derivatives have the potential for unlimited losses, regardless of the size of
 the initial investment.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- - how each Fund's average annual total returns compare to indexes shown in the
  table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts. If sales charges
were included, the returns would be lower.


                                       32





Tables. The first tables show total returns from hypothetical investments in
Class A, Class B, Class C, Class R and Class I shares of Seligman Core Fixed
Income Fund. The second table shows total returns from hypothetical investments
in Class A, Class B, Class C, Class R2 and Class R5 shares of the RiverSource
Diversified Bond Fund. These returns are compared to the indexes shown for the
same periods. For purposes of the performance calculation in the table we
assumed:

- - the maximum sales charge of 4.50% for Class A shares of the Selling Fund* and
  4.75% for Class A shares of the Buying Fund;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B, Class C** and Class R shares;

- - no sales charge for Class R2, Class R5 and Class I shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

  * Effective Jan. 7, 2008, the maximum initial sales charge in Class A shares
    of the Selling Fund is 4.50%. Although for all periods presented the Selling
    Fund's Class A share returns reflect the 4.50% maximum initial sales charge,
    the actual returns for periods prior to Jan. 7, 2008 would have been lower
    if a 4.75% maximum initial sales charge then in effect was incurred.

 ** Effective June 4, 2007, there is no initial sales charge on purchases of
    Class C shares of the Selling Fund. Although for all periods presented the
    Selling Fund's Class C share returns do not reflect an initial sales charge,
    the actual returns for periods prior to June 4, 2007 would have been lower
    if a 1.00% maximum initial sales charge then in effect was incurred.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

The Barclays Capital U.S. Universal Index, an unmanaged index, measures the
performance of U.S. dollar-denominated, taxable bonds that are rated either
investment grade or below investment grade. The index reflects reinvestment of
all distributions and changes in market prices and reflects no deduction for
fees, expenses or taxes.

The Lipper Intermediate Investment-Grade Debt Funds Average measures the
performance of mutual funds that invest at least 65% of their assets in
investment-grade debt issues rated in the top four grades with dollar-weighted
average maturities of five to ten years. The average is an unmanaged benchmark
that assumes the reinvestment of all distributions and does not reflect any
sales charges or taxes.

The Lipper Intermediate Investment Grade Index includes the 30 largest
investment grade funds tracked by Lipper Inc. The index's returns include net
reinvested dividends.

Investors cannot invest directly in an average or index.

PROPOSAL 2. REORGANIZATION OF SELIGMAN EMERGING MARKETS FUND INTO THREADNEEDLE
EMERGING MARKETS FUND

COMPARISON OF INVESTMENT OBJECTIVES

Each Fund seeks long-term capital appreciation and invests predominantly in
equity securities of emerging markets companies.

The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman Emerging Markets Fund seeks long-term capital
                        appreciation.

          BUYING FUND: Threadneedle Emerging Markets Fund seeks to provide
                       shareholders with long-term capital growth.

Because any investment involves risk, there is no assurance the Fund's objective
can be achieved. Only shareholders can change the Fund's objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests primarily in equity securities of emerging markets companies.
Each Fund may enter into forward foreign currency exchange contracts as part of
its principal investment strategy.

The Selling Fund defines an emerging market as a market in a developing country
or a market represented in the Morgan Stanley Capital International Emerging
Markets Index. The Selling Fund defines developing countries as those classified
by the World Bank as low-income or middle-income economies, regardless of their
particular stage of development. The Buying Fund defines emerging markets as
countries characterized as developing or emerging by either the World Bank or
the United Nations. The Buying Fund may also invest in securities of companies
that earn 50% or more of their total revenues from goods or services produced in
emerging market countries or from sales made in emerging markets countries.

RiverSource Investments serves as the investment manager for each Fund and is
responsible for the oversight of each Fund's subadviser, which provides day-to-
day management of the Fund. The Selling Fund is subadvised by Wellington
Management Company, LLP ("Wellington") and the Buying Fund is subadvised by
Threadneedle International Limited ("Threadneedle"), an indirect wholly-owned
subsidiary of Ameriprise Financial, Inc.

DETAILED STRATEGIES FOR THE SELLING FUND AND THE BUYING FUND ARE SET FORTH
BELOW:

SELIGMAN EMERGING MARKETS FUND (SELLING FUND)

The Fund generally invests at least 80% of its net assets in equity securities
of companies that conduct their principal business activities in emerging
markets, are organized under the laws of or maintain their principal place of
business in emerging markets, or whose securities are traded principally on
exchanges in emerging markets. The Fund will focus its investments in those
emerging markets in which the investment manager believes the economies are
developing strongly and markets are becoming more liquid, or other emerging
markets that meet the portfolio manager's criteria for investability. The Fund
seeks to benefit from policies of economic development being adopted in many
emerging markets. These policies include domestic price reform, reducing
internal budget deficits, privatization, encouraging foreign investments, and
developing capital markets.

The Fund combines a bottom-up investment style with top-down analysis of
regions, countries and sectors. This means the portfolio manager incorporates
analysis of individual companies along with analysis of individual sectors,
countries and regions.

In selecting individual securities, the portfolio manager looks to identify
companies that it believes display one or more of the following:

- - Operate in growing markets

- - Attractive valuations relative to cash earnings forecasts or other valuation
  criteria

- - Unique sustainable competitive advantages (e.g., market share, proprietary
  products)

- - Improving industry or country fundamentals

Following stock selection, the portfolio manager then focuses on portfolio
construction that considers top-down risk control based on such factors as:

- - Relative economic growth potential of the various economies and securities
  markets

- - Political, financial, and social conditions influencing investment
  opportunities

- - Relative rates of earnings growth

- - Interest rate outlook and expected levels of inflation

- - Market prices relative to historic averages


                                       36



The Fund generally sells a stock if the portfolio manager believes its target
price has been reached, its earnings are disappointing, its revenue growth has
slowed, its underlying fundamentals have deteriorated, or there are
deteriorating industry or country fundamentals. The Fund may also sell or trim a
stock if the portfolio manager believes, from a risk control perspective, the
stock's position size is inappropriate for the portfolio. Also, stocks may be
sold when negative country, currency, or general industry factors affect a
company's outlook, or to meet cash requirements.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the U.S. dollar. The securities may be
listed on a U.S. or foreign stock exchange or traded in U.S. or foreign over-
the-counter markets. The Fund normally concentrates its investments in common
stocks; however, it may invest in other types of equity securities, including
securities convertible into or exchangeable for common stock, depositary
receipts, and rights and warrants to purchase common stock. The Fund also may
invest up to 20% of its assets in preferred stock and investment-grade or
comparable quality debt securities.

The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds in its
portfolio. A put option gives the Fund the right to sell an underlying security
at a particular price during a fixed period of time. Forward foreign currency
exchange contracts and put options on securities may not be available to the
Fund on reasonable terms in many situations, and the Fund may frequently choose
not to enter into such contracts or purchase such options even when they are
available.

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 may also invest up to 10% of its assets in exchange-traded funds
("ETFs"). ETFs are traded, like individual stocks, on an exchange, but they
represent baskets of securities that seek to track the performance of certain
indices. The indices include not only broad-market indices but more specific
indices as well, including those relating to particular sectors, countries and
regions. The Fund may invest in ETFs for short-term cash management purposes or
as part of its overall investment strategy.

THREADNEEDLE EMERGING MARKETS FUND (BUYING FUND)

The Fund's assets are primarily invested in equity securities of emerging
markets companies. Emerging markets are countries characterized as developing or
emerging by either the World Bank or the United Nations. Under normal market
conditions, at least 80% of the Fund's net assets will be invested in securities
of companies that are located in emerging markets countries, or that earn 50% or
more of their total revenues from goods or services produced in emerging markets
countries or from sales made in emerging markets countries. The Fund will
provide shareholders with at least 60 days' notice of any change in the 80%
policy.

RiverSource Investments serves as the investment manager to the Fund and is
responsible for oversight of Threadneedle, the Fund's subadviser.

Threadneedle chooses investments by:

- - Deploying an integrated approach to equity research that incorporates regional
  analyses, a global sector strategy, and stock specific perspectives.

- - Conducting detailed research on companies in a consistent strategic and
  macroeconomic framework.

- - Looking for catalysts of change and identifying the factors driving markets,
  which will vary over economic and market cycles.

- - Implementing rigorous risk control processes that seek to ensure that the risk
  and return characteristics of the Fund's portfolio are consistent with
  established portfolio management parameters.

The Fund's portfolio management team constructs the portfolio by selecting what
it considers to be the best stocks in each industry sector, based on return on
invested capital analysis, growth and valuation. The Fund's sector exposure
generally reflects the global macroeconomic environment, the outlook for each
sector and the relative valuation of the stocks among the sectors.

The Fund's portfolio management team constructs the portfolio by investing in
most of the stocks on two core lists of holdings: the Largest Companies List and
the Preferred List. In addition, the portfolio will hold other securities
selected by the portfolio management team. These discretionary holdings will
typically make up a much smaller portion of the Fund.


                                       37



- - The Largest Companies List includes the largest stocks in the Fund's
  benchmark, the Morgan Stanley Capital International ("MSCI") Emerging Markets
  Index. Threadneedle's research on sectors and specific companies is used to
  determine recommended weightings for each stock.

- - The Preferred List includes the stocks not included in the Largest Companies
  List that represent the best ideas generated by Threadneedle's research
  analysts.

  Stocks on the Preferred List are selected by:

     - Analyzing returns on invested capital for the largest companies within
       each sector;

     - Assessing valuations; and

     - Evaluating one or more of the following: balance sheets and cash flows,
       the demand for a company's products or services, its competitive
       position, or its management.

  The Fund will normally be overweight in the stocks on the Preferred List
  compared to the benchmark.

- - Discretionary holdings are selected by the individual portfolio management
  team based on the same criteria used to generate the Preferred List. These
  stocks are assigned ratings based on their perceived ability to outperform
  within their sector. The team typically selects the highest rated stocks
  outside the core category.

A number of factors may prompt the portfolio management team to sell securities.
A sale may result from a change in the composition of the Fund's benchmark or a
change in sector strategy. A sale may also be prompted by factors specific to a
stock, such as valuation or company fundamentals.

The Fund will normally have exposure to foreign currencies. The portfolio
management team closely monitors the Fund's exposure to foreign currency. From
time to time the team may use forward currency transactions or other derivative
instruments to hedge against currency fluctuations.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

For purposes of this discussion, a "fundamental" investment policy is one that
may not be changed without a shareholder vote. The Funds' fundamental investment
policies are set forth below:

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives, principal investment strategies and
investment policies. With regards to investment policies, the Buying Fund may
expose shareholders to greater liquidity risk due to the Buying Fund's greater
ability to invest in illiquid securities. The actual risks of investing in each
Fund depend on the securities held in each Fund's portfolio and on market
conditions, both of which change over time. Both Funds are subject to the
principal investment risks described below.

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

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains

                                       40



  or losses involving derivative instruments may be substantial, because a
  relatively small price movement in the underlying security(ies), instrument,
  currency or index may result in a substantial gain or loss for the Fund.
  Derivative instruments in which the Fund invests will typically increase the
  Fund's exposure to principal risks to which it is otherwise exposed, and may
  expose the Fund to additional risks, including counterparty credit risk,
  hedging risk, correlation risk, liquidity risk and leverage risk.

  Counterparty credit risk is the risk that a counterparty to the derivative
  instrument becomes bankrupt or otherwise fails to perform its obligations due
  to financial difficulties, and the Fund may obtain no recovery of its
  investment or may only obtain a limited recovery, and any recovery may be
  delayed.

  Hedging risk is the risk that derivative instruments used to hedge against an
  opposite position may offset losses, but they may also offset gains.

  Correlation risk is related to hedging risk and is the risk that there may be
  an incomplete correlation between the hedge and the opposite position, which
  may result in increased or unanticipated losses.

  Liquidity risk is the risk that the derivative instrument may be difficult or
  impossible to sell or terminate, which may cause the Fund to be in a position
  to do something the investment manager would not otherwise choose, including
  accepting a lower price for the derivative instrument, selling other
  investments or foregoing another, more appealing investment opportunity.

  Leverage risk is the risk that losses from the derivative instrument may be
  greater than the amount invested in the derivative instrument. Certain
  derivatives have the potential for unlimited losses, regardless of the size of
  the initial investment.

- - RISKS OF FOREIGN INVESTING. Foreign securities are securities of issuers based
  outside the United States. An issuer is deemed to be based outside the United
  States if it is organized under the laws of another country. Foreign
  securities are primarily denominated in foreign currencies. In addition to the
  risks normally associated with domestic securities of the same type, foreign
  securities are subject to the following foreign risks:

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

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

  Custody risk refers to the process of clearing and settling trades. It also
  covers holding securities with local agents and depositories. Low trading
  volumes and volatile prices in less developed markets make trades harder to
  complete and settle. Local agents are held only to the standard of care of the
  local market. Governments or trade groups may compel local agents to hold
  securities in designated depositories that are not subject to independent
  evaluation. The less developed a country's securities market is, the greater
  the likelihood of problems occurring.

  Emerging markets risk includes the dramatic pace of change (economic, social
  and political) in these countries as well as the other considerations listed
  above. These markets are in early stages of development and are extremely
  volatile. They can be marked by extreme inflation, devaluation of currencies,
  dependence on trade partners, and hostile relations with neighboring
  countries.

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

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

- - SECTOR RISK. Investments that are concentrated in a particular issuer,
  geographic region or sector will be more susceptible to changes in price. The
  more a fund diversifies across sectors, the more it spreads risk and
  potentially reduces the risks of loss and volatility.

- - SMALL AND MID-SIZED COMPANY RISK. Investments in small and medium companies
  often involve greater risks than investments in larger, more established
  companies because small and medium companies may lack the management

                                       41



  experience, financial resources, product diversification, experience and
  competitive strengths of larger companies. Additionally, in many instances the
  securities of small and medium companies are traded only over-the-counter or
  on regional securities exchanges and the frequency and volume of their trading
  is substantially less and may be more volatile than is typical of larger
  companies.

In addition to the risks described above, the Buying Fund is subject to the
additional principal investment risk set forth below. While this additional risk
may also be a risk of the Selling Fund, it is not stated as a principal
investment risk of the Selling Fund. For more information regarding the Selling
Fund's principal investment risks, see "Principal Risks" in the Selling Fund's
prospectus.

- - GEOGRAPHIC CONCENTRATION RISK. The Fund may be particularly susceptible to
  economic, political or regulatory events affecting companies and countries
  within the specific geographic region in which the Fund focuses its
  investments. Currency devaluations could occur in countries that have not yet
  experienced currency devaluation to date, or could continue to occur in
  countries that have already experienced such devaluations. As a result, the
  Fund may be more volatile than a more geographically diversified fund.

In addition to the risks described above, the Selling Fund is subject to the
risks associated with investing in debt securities, including high-yield bonds
(junk bonds), including the risks set forth below. While these additional risks
may also be risks of the Buying Fund, they are not stated as principal
investment risks of the Buying Fund. For more information regarding the Buying
Fund's principal investment risks, see "Principal Risks" in the Buying Fund's
prospectus.

- - CREDIT RISK. Credit risk is the risk that the issuer of a security, or the
  counterparty to a contract, will default or otherwise become unable or
  unwilling to honor a financial obligation, such as payments due on a bond or a
  note. If the Fund purchases unrated securities, or if the rating of a security
  is reduced after purchase, the Fund will depend on the investment manager's
  analysis of credit risk more heavily than usual. Non-investment grade
  securities, commonly called high yield or junk bonds, may react more to
  perceived changes in the ability of the issuing entity to pay interest and
  principal when due than to changes in interest rates. Non-investment grade
  securities have greater price fluctuations and are more likely to experience a
  default than investment grade bonds.

- - INTEREST RATE RISK. Interest rate risk is the risk of losses attributable to
  changes in interest rates. Interest rate risk is generally associated with
  bond prices: when interest rates rise, bond prices fall. In general, the
  longer the maturity or duration of a bond, the greater its sensitivity to
  changes in interest rates.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- - how each Fund's average annual total returns compare to indexes shown in the
  table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts. If sales charges
were included, the returns would be lower.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class R and Class I shares of Seligman Emerging
Markets Fund. The second table shows total returns from hypothetical investments
in Class A, Class B and Class C shares of the Threadneedle Emerging Markets
Fund. The inception date for Class R2 of the Buying Fund is expected to be in
the third quarter of 2009 and therefore performance information for that class
is not shown. Class R5 of the Buying Fund has not been in existence for a full
calendar year and therefore performance for that class is not shown. These
returns are compared to the indexes shown for the same periods. For purposes of
the performance calculation in the table we assumed:

- - the maximum sales charge of 5.75%* for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B, Class C** and Class R shares;

- - no sales charge for Class I shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

  * Effective Jan. 7, 2008, the maximum initial sales charge on investments in
    Class A shares of the Selling Fund is 5.75%. Although for all periods
    presented, the Selling Fund's Class A share returns reflect the 5.75%
    maximum initial sales charge, the actual returns for periods prior to Jan.
    7, 2008 would have been higher if a 4.75% maximum initial sales charge then
    in effect was incurred.

 ** Effective June 4, 2007, there is no initial sales charge on purchases of
    Class C shares of the Selling Fund. Although for all periods presented in
    the tables the Selling Funds' Class C share returns do not reflect an
    initial sales charge, the actual returns for periods prior to June 4, 2007
    would have been lower if a 1.00% maximum initial sales charge then in effect
    was incurred.


                                       43



AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

The Buying Fund formerly was a "feeder" fund in a master/feeder arrangement
where the Buying Fund invested all of its assets in a corresponding "master"
fund with an identical investment objective and investment strategies. As of
Nov. 8, 2005, the Buying Fund became a stand-alone fund that invests directly in
a portfolio of securities. The information shown in the table and in the
financial highlights for the Buying Fund includes the activity of the Buying
Fund when it was a feeder in a master/feeder arrangement.

The MSCI Emerging Markets Index, an unmanaged market capitalization weighted
index, is designed to measure equity market performance in the global emerging
markets. The index reflects reinvestment of all distributions and changes in
market prices and reflects no deduction for fees, expenses or taxes.

The Lipper Emerging Markets Funds Average comprises mutual funds which seek
long-term capital appreciation by investing at least 65% of total assets in
emerging market equity securities, where "emerging market" is defined by a
country's gross national product (GNP) per capita or other economic measures.
The average is an unmanaged benchmark that assumes the reinvestment of all
distributions, if any, and excludes the effect of fees, sales charges and taxes.

The Lipper Emerging Markets Funds Index includes the 30 largest emerging markets
funds tracked by Lipper Inc. The index's returns include net reinvested
dividends. The Buying Fund's performance is currently measured against this
index for purposes of determining the performance incentive adjustment. See Fund
Management and Compensation in Exhibit B for more information.

Investors cannot invest directly in an average or index.

The inception date for Class R2 of the Buying Fund is expected to be in the
third quarter of 2009 and therefore performance information for that class is
not shown. Class R5 of the Buying Fund has not been in existence for a full
calendar year and therefore performance for that class is not shown.

PROPOSAL 3. REORGANIZATION OF SELIGMAN GLOBAL GROWTH FUND INTO THREADNEEDLE
GLOBAL EQUITY FUND

COMPARISON OF INVESTMENT OBJECTIVES

Each Fund seeks long-term capital appreciation and invests predominantly in
equity securities. The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman Global Growth Fund seeks long-term capital
                        appreciation.

          BUYING FUND: Threadneedle Global Equity Fund seeks to provide
                       shareholders with long-term capital growth.

Because any investment involves risk, there is no assurance the Fund's objective
can be achieved. Only shareholders can change the Fund's objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Selling Fund invests at least 40% of its net
assets in the securities of non-U.S. companies (as described below), while the
Buying Fund has no similar restrictions. The Selling Fund may invest up to 15%
of its assets in emerging market equities and up to 25% of its assets in
preferred stock and investment grade or comparable quality debt securities,
while the Buying Fund has no comparable restrictions. Each Fund may enter into
forward foreign currency exchange contracts or use derivatives as part of its
principal investment strategies.

RiverSource Investments serves as the investment manager for each Fund and is
responsible for the oversight of each Fund's subadviser, which provides day-to-
day management of the Fund. The Selling Fund is subadvised by Wellington
Wellington and the Buying Fund is subadvised by Threadneedle, an indirect
wholly-owned subsidiary of Ameriprise Financial, Inc.

DETAILED STRATEGIES FOR THE SELLING FUND AND THE BUYING FUND ARE SET FORTH
BELOW:

SELIGMAN GLOBAL GROWTH FUND (SELLING FUND)

The Fund invests primarily in equity securities of non-U.S. and U.S. growth
companies that have the potential to benefit from global economic or social
trends. The Fund may invest in high quality, large and mid-capitalization
companies that are considered leaders in their industries, emphasizing those
industries that are growing on a global basis. Typically, the Fund will invest
in several countries in different geographic regions. Additionally, the Fund may
invest up to 15% in emerging market equities.

Under normal market conditions, the Fund generally will invest at least 40% of
its net assets in companies that maintain their principal place of business or
conduct their principal business activities outside the U.S., have their
securities traded on non-U.S. exchanges or have been formed under the laws of
non-U.S. countries. The portfolio manager may reduce this 40% minimum investment
amount to 30% if it believes that market conditions for these types of companies
or specific foreign markets are unfavorable. The Fund considers a company to
conduct its principal business activities outside the U.S. if it derives at
least 50% of its revenue from business outside the U.S. or has at least 50% of
its assets outside the U.S.

The Fund uses an investment process that emphasizes bottom-up research with a
focus on companies with improving fundamentals exemplified by identifiable
catalysts and strong earnings growth.

In selecting individual securities, the portfolio manager looks to identify
companies that it believes display one or more of the following:

- - Accelerating fundamentals or earnings growth with consideration paid to
  valuations

- - Quality management

- - Strong possibility of multiple expansion

- - Unique competitive advantages (e.g., market share, proprietary products)

- - Potential for improvement in overall operations

The Fund generally sells a stock if the portfolio manager believes its target
price has been reached, its earnings are disappointing, its revenue or earnings
growth has slowed, or the stock's or industry's underlying fundamentals have
deteriorated. The Fund may also sell a stock if the portfolio manager believes
that negative country or regional factors or shifts in global trends may
negatively affect a company's outlook, or to meet cash requirements.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the U.S. dollar. The Fund normally
concentrates its investments in common stocks; however, it may invest in other
types of equity securities, including securities convertible into or
exchangeable for common stock, depositary receipts, and rights and warrants to
purchase common stock. The Fund also may invest up to 25% of its assets in
preferred stock and investment grade or comparable quality debt securities.


                                       47



The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds in its
portfolio. A put option gives the Fund the right to sell an underlying security
at a particular price during a fixed period of time. Forward foreign currency
exchange contracts and put options on securities may not be available to the
Fund on reasonable terms in many situations, and the Fund may frequently choose
not to enter into such contracts or purchase such options even when they are
available.

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 may also invest up to 10% of its assets in exchange-traded funds
("ETFs"). ETFs are traded, like individual stocks, on an exchange, but they
represent baskets of securities that seek to track the performance of certain
indices. The indices include not only broad-market indices but more specific
indices as well, including those relating to particular sectors, countries and
regions. The Fund may invest in ETFs for short-term cash management purposes or
as part of its overall investment strategy.

THREADNEEDLE GLOBAL EQUITY FUND (BUYING FUND)

Under normal market conditions, at least 80% of the Fund's net assets will be
invested in equity securities, including companies located in developed and
emerging countries. The Fund will provide shareholders with at least 60 days'
notice of any change in the 80% policy.

RiverSource Investments serves as the investment manager to the Fund and is
responsible for oversight of Threadneedle, the Fund's subadviser.

Threadneedle chooses investments by:

- - Deploying an integrated approach to equity research that incorporates regional
  analyses, a global sector strategy, and stock specific perspectives.

- - Conducting detailed research on companies in a consistent strategic and
  macroeconomic framework.

- - Looking for catalysts of change and identifying the factors driving markets,
  which will vary over economic and market cycles.

- - Implementing rigorous risk control processes that seek to ensure that the risk
  and return characteristics of the Fund's portfolio are consistent with
  established portfolio management parameters.

Using the global sector strategy, Threadneedle constructs the portfolio by
investing in most of the stocks on two core lists of holdings: the Largest
Companies List and the Preferred List. In addition, the portfolio will hold
other securities selected by the portfolio management team. These discretionary
holdings will typically make up a much smaller portion of the Fund.

- - The Largest Companies List includes the largest stocks in the Fund's
  benchmark, the Morgan Stanley Capital International (MSCI) All Country World
  Index. Threadneedle's research on regions, sectors, and specific companies is
  used to determine recommended weightings for each stock.

- - The Preferred List includes the stocks not included in the Largest Companies
  List that represent the best ideas generated by Threadneedle's research area.

Stocks on the Preferred List are selected by:

- - Evaluating the opportunities and risks within regions and sectors;

- - Assessing valuations; and

- - Evaluating one or more of the following: balance sheets and cash flows, the
  demand for a company's products or services, its competitive position, or its
  management. The Fund will normally be overweight in the stocks on the
  Preferred List compared to the benchmark.

- - Discretionary holdings are selected by the individual portfolio management
  team based on the same criteria used to generate the Preferred List. These
  stocks are assigned ratings based on their perceived ability to outperform
  within their sector. The team typically selects the highest rated stocks
  outside the core category.

A number of factors may prompt Threadneedle to sell securities. A sale may
result from a change in the composition of the Fund's benchmark or a change in
sector strategy. A sale may also be prompted by factors specific to a stock,
such as valuation or company fundamentals.


                                       48



The Fund will normally have exposure to foreign currencies. Threadneedle closely
monitors the Fund's exposure to foreign currency. From time to time the team may
use forward currency transactions or other derivative instruments to hedge
against currency fluctuations.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

For purposes of this discussion, a "fundamental" investment policy is one that
may not be changed without a shareholder vote. The Funds' fundamental investment
policies are set forth below:

COMPARISON OF NONFUNDAMENTAL POLICIES AND RELATED INVESTMENT STRATEGIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies of the Buying Fund. RiverSource Investments
does not believe that the differences between the nonfundamental policies of the
Funds result in any material differences in the way the Funds have been managed
or in the way the combined Fund will be managed.

The following highlights the differences in the Funds' nonfundamental investment
policies (policies that may be changed without a shareholder vote):

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives, principal investment strategies and
investment policies. With regards to investment policies, the Buying Fund may
expose shareholders to greater emerging markets risk due to the Buying Fund's
greater ability to invest in emerging market equities. The Buying Fund may also
expose shareholders to greater liquidity risk due to the Buying Fund's greater
ability to invest in illiquid securities. The actual risks of investing in each
Fund depend on the securities held in each Fund's portfolio and on market
conditions, both of which change over time. Both Funds are subject to the
principal investment risks described below.

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

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  correlation risk, counterparty credit risk, hedging risk, leverage risk and
  liquidity risk.

 Correlation risk is related to hedging risk and is the risk that there may be
 an incomplete correlation between the hedge and the opposite position, which
 may result in increased or unanticipated losses.

 Counterparty credit risk is the risk that a counterparty to the derivative
 instrument becomes bankrupt or otherwise fails to perform its obligations due
 to financial difficulties, and the Fund may obtain no recovery of its
 investment or may only obtain a limited recovery, and any recovery may be
 delayed.

 Hedging risk is the risk that derivative instruments used to hedge against an
 opposite position may offset losses, but they may also offset gains.

 Leverage risk is the risk that losses from the derivative instrument may be
 greater than the amount invested in the derivative instrument. Certain
 derivatives have the potential for unlimited losses, regardless of the size of
 the initial investment.


                                       51



 Liquidity risk is the risk that the derivative instrument may be difficult or
 impossible to sell or terminate, which may cause the Fund to be in a position
 to do something the investment manager would not otherwise choose, including
 accepting a lower price for the derivative instrument, selling other
 investments or foregoing another, more appealing investment opportunity.

- - RISKS OF FOREIGN INVESTING. Foreign securities are securities of issuers based
  outside the United States. An issuer is deemed to be based outside the United
  States if it is organized under the laws of another country. Foreign
  securities are primarily denominated in foreign currencies. In addition to the
  risks normally associated with domestic securities of the same type, foreign
  securities are subject to the following foreign risks:

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

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

 Custody risk refers to the process of clearing and settling trades. It also
 covers holding securities with local agents and depositories. Low trading
 volumes and volatile prices in less developed markets make trades harder to
 complete and settle. Local agents are held only to the standard of care of the
 local market. Governments or trade groups may compel local agents to hold
 securities in designated depositories that are not subject to independent
 evaluation. The less developed a country's securities market is, the greater
 the likelihood of problems occurring.

 Emerging markets risk includes the dramatic pace of change (economic, social
 and political) in these countries as well as the other considerations listed
 above. These markets are in early stages of development and are extremely
 volatile. They can be marked by extreme inflation, devaluation of currencies,
 dependence on trade partners, and hostile relations with neighboring countries.

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

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

In addition to the risks described above, the Buying Fund is subject to the
additional principal investment risk set forth below. While this additional risk
may also be a risk of the Selling Fund, it is not stated as a principal
investment risk of the Selling Fund. For more information regarding the Selling
Fund's principal investment risks, see "Principal Risks" in the Selling Fund's
prospectus.

- - GEOGRAPHIC CONCENTRATION RISK. The Fund may be particularly susceptible to
  economic, political or regulatory events affecting companies and countries
  within the specific geographic region in which the Fund focuses its
  investments. Currency devaluations could occur in countries that have not yet
  experienced currency devaluation to date, or could continue to occur in
  countries that have already experienced such devaluations. As a result, the
  Fund may be more volatile than a more geographically diversified fund.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- - how each Fund's average annual total returns compare to indexes shown in the
  table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts. If sales charges
were included, the returns would be lower.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class R and Class I shares of Seligman Global Growth
Fund. The second table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class R2 and Class R5 shares of the Threadneedle
Global Equity Fund. These returns are compared to the indexes shown for the same
periods. For purposes of the performance calculation in the table we assumed:

- - the maximum sales charge of 5.75%* for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B, Class C** and Class R shares;

- - no sales charge for Class R2, Class R5 and Class I shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

  * Effective Jan. 7, 2008, the maximum initial sales charge on investments in
    Class A shares of the Selling Fund is 5.75%. Although for all periods
    presented, the Selling Fund's Class A share returns reflect the 5.75%
    maximum initial sales charge, the actual returns for periods prior to Jan.
    7, 2008 would have been higher if a 4.75% maximum initial sales charge then
    in effect was incurred.

 ** Effective June 4, 2007, there is no initial sales charge on purchases of
    Class C shares of the Selling Fund. Although for all periods presented in
    the tables the Selling Funds' Class C share returns do not reflect an
    initial sales charge, the actual returns for periods prior to June 4, 2007
    would have been lower if a 1.00% maximum initial sales charge then in effect
    was incurred.


                                       53



AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

The Buying Fund formerly was a "feeder" fund in a master/feeder arrangement
where the Buying Fund invested all of its assets in a corresponding "master"
fund with an identical investment objective and investment strategies. As of
Nov. 8, 2005, the Buying Fund became a stand-alone fund that invests directly in
a portfolio of securities. The information shown in the table and in the
financial highlights for the Buying Fund includes the activity of the Buying
Fund when it was a feeder in a master/feeder arrangement.

Prior to March 31, 2000, J. & W. Seligman & Co. Incorporated (the predecessor
investment manager) employed subadvisers that were responsible for providing
certain portfolio management services with respect to the investments of the
Fund. From March 31, 2000 until Sept. 15, 2003, the assets of the Fund were
managed exclusively by Seligman. Since Sept. 15, 2003, Wellington Management
Company LLP has been employed as subadviser to provide portfolio management
services to the Fund.

The MSCI World Index, an unmanaged index, is a free float-adjusted market
capitalization index that is designed to measure global developed market equity
performance. The index reflects reinvestment of all distributions and changes in
market prices and reflects no deduction for fees, expenses or taxes.

The MSCI World Growth Index, an unmanaged index, is a free float-adjusted market
capitalization-weighted equity index representing "growth" (high price to book
value) securities in the world's developed stock markets. The index reflects
reinvestment of all distributions and changes in market prices and reflects no
deduction for fees, expenses or taxes.

The Lipper Global Large-Cap Growth Funds Average comprises mutual funds that, by
portfolio practice, invest at least 75% of their equity assets in companies both
inside and outside of the United States with market capitalizations (on a three-
year weighted basis) above Lipper's global large-cap floor. Global large-cap
growth funds typically have an above-average price-to-cash flow ratio, price-to-
book ratio, and three-year sales-per-share growth value compared to their large-
cap-specific subset of the S&P/Citigroup World Broad Market Index (BMI). Lipper
currently classifies the Selling Fund as a Global Large-Cap Growth Fund. The
average is an unmanaged benchmark that assumes reinvestment of all
distributions, if any, and excludes the effect of fees, sales charges and taxes.

The Lipper Global Funds Average comprises mutual funds which invest at least 25%
of their portfolio in securities traded outside the United States, and may own
U.S. securities as well. The average is an unmanaged benchmark that assumes
reinvestment of all distributions, if any, and excludes the effect of fees,
sales charges and taxes.

The MSCI All Country World Index, an unmanaged index of equity securities, is
designed to measure equity market performance in the global developed and
emerging markets. The index reflects reinvestment of all distributions and
changes in market prices and reflects no deduction for fees, expenses or taxes.

The Lipper Global Funds Index includes the 30 largest global funds tracked by
Lipper Inc. The index's returns include net reinvested dividends. The Buying
Fund's performance is currently measured against this index for purposes of
determining the performance incentive adjustment. See Fund Management and

PROPOSAL 4. REORGANIZATION OF SELIGMAN HIGH-YIELD FUND INTO RIVERSOURCE HIGH
YIELD BOND FUND

Shareholders of both the Buying Fund and the Selling Fund may be entitled to
assert appraisal rights (also known as dissenters' rights of appraisal) under
provisions of Minnesota and Massachusetts state law, respectively. Please see
the discussion under the caption Appraisal Rights in Section C of this proxy
statement/prospectus for more information, including a comparison of appraisal
rights under Minnesota and Massachusetts state law. A copy of the appraisal
rights under the Massachusetts Business Corporation Act is also included as
Appendix D in this proxy statement/prospectus.

COMPARISON OF INVESTMENT OBJECTIVES

Each Fund seeks a high level of current income, with capital appreciation as a
secondary objective.

The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman High-Yield Fund seeks a high level of current
                        income and may also consider the potential for capital
                        appreciation consistent with prudent investment
                        management.

          BUYING FUND: RiverSource High Yield Bond Fund seeks to provide
                       shareholders with high current income as its primary
                       objective and, as its secondary objective, capital
                       growth.

Because any investment involves risk, there is no assurance the Fund's objective
can be achieved. Only shareholders can change the Fund's objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests predominantly in non-investment grade, high yield securities.
The Selling Fund may invest up to 10% of its assets in equity-linked securities
(each, an "ELS"), while the Buying Fund has no similar limitation. The Buying
Fund may invest up to 25% of its assets in high yield debt instruments of
foreign issuers. Although the Selling Fund does not include it as a principal
investment strategy, the Selling Fund may invest up to 10% of its net assets in
debt securities of foreign issuers. The Buying Fund counts American Depositary
Receipts ("ADRs") toward its 25% limit, but ADRs are excluded from the Selling
Fund's 10% limitation.

DETAILED STRATEGIES FOR THE SELLING FUND AND THE BUYING FUND ARE SET FORTH
BELOW:

SELIGMAN HIGH-YIELD FUND (SELLING FUND)

The Fund invests 80% of its net assets in non-investment grade, high yield
securities ("High Yield Securities"). High Yield Securities (many of which are
commonly known as junk bonds) carry non-investment grade ratings (Ba or below by
Moody's or BB or below by Fitch or S&P) or are securities deemed to be below
investment grade by the investment manager. High Yield Securities have the
potential to offer higher yields than investment grade securities with higher
ratings and similar maturities. High Yield Securities are subject to greater
risk of loss of principal and interest than higher rated investment grade
securities. The Fund may invest in all types of High Yield Securities including:

- - Senior and subordinated corporate debt obligations of both U.S. and non-U.S.
  issuers (including, for example debentures, loan participations and floating
  rate notes);

- - Mortgage and other asset-backed securities;

- - Capital appreciation bonds, including zero coupon and pay-in-kind securities;

- - Convertible securities, preferred stock, structured securities and loan
  participations;

- - Municipal securities;

- - Obligations of foreign governments;

- - Securities that are rated in default by a nationally recognized statistical
  rating organization;

- - Repurchase agreements relating to the above instruments;

- - Warrants, rights and other equity securities that are acquired in connection
  with the Fund's investments in High Yield Securities; and

- - Restricted securities that may be offered and sold only to "qualified
  institutional buyers" under Rule 144A of the Securities Act of 1933 ("Rule
  144A Securities").

In addition, the Fund may invest up to 20% of its net assets in (i) securities
of higher quality, including: short-term money market instruments, including
certificates of deposit of FDIC member banks having total assets of $1 billion
or more; bankers' acceptances and interest-bearing savings or time deposits of
such banks; commercial paper; investment grade fixed-income securities;
securities issued, guaranteed or insured by the U.S. government, its agencies or
instrumentalities as well as any government sponsored enterprise; and other
income-producing cash items and (ii) warrants, rights and other equity
securities

                                       58



that are not acquired in connection with the Fund's investments in High Yield
Securities. The Fund may invest up to 15% of its net assets in illiquid
securities (i.e., securities that cannot be readily sold). Rule 144A Securities
deemed to be liquid by the investment manager are not included in this
limitation. The Fund does not have any portfolio maturity limitation, and may
invest its assets in instruments with short, medium or long maturities.

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

- - Reviewing interest rate and economic forecasts.

- - Reviewing credit characteristics and capital structures of companies,
  including an evaluation of any outstanding bank loans or corporate debt
  securities a company has issued, its relative position in its industry, and
  its management team's capabilities.

- - Identifying companies that:

  - have medium and low quality ratings or, in the investment manager's opinion,
    have similar qualities to companies with medium or low quality ratings, even
    though they are not rated, or have been given a different rating by a rating
    agency,

  - have growth potential, or

  - have the potential to increase in value as their credit ratings improve.

- - Buying debt instruments that are expected to outperform other debt
  instruments.

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

- - The interest rate or economic outlook changes.

- - A sector or industry is experiencing change.

- - A security's rating is changed.

- - The security is overvalued relative to alternative investments.

- - The company no longer meets the investment manager's performance expectations.

- - The investment manager wishes to lock in profits.

- - The investment manager identifies a more attractive opportunity.

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

The Fund may also invest up to 10% of its assets in ELSs as part of its overall
investment strategy. An ELS is a debt instrument whose value is based on the
value of a single equity security, basket of equity securities or an index of
equity securities (each, an "Underlying Equity"). An ELS typically provides
interest income, thereby offering a yield advantage over investing directly in
an Underlying Equity. However, the holder of an ELS may have limited or no
benefit from any appreciation in the Underlying Equity, but is exposed to
downside market risk. The Fund may purchase ELSs that trade on a securities
exchange or those that trade on the over-the-counter markets, including Rule
144A Securities. The Fund may also purchase an ELS in a privately negotiated
transaction with the issuer of the ELS (or its broker-dealer affiliate).

RIVERSOURCE HIGH YIELD BOND FUND (BUYING FUND)

Under normal market conditions, the Fund will invest at least 80% of its net
assets in high yield debt instruments (commonly referred to as junk bonds).
These high yield debt instruments include corporate debt securities as well as
bank loans rated below investment grade by a nationally recognized statistical
rating organization, or if unrated, determined to be of comparable quality. Up
to 25% of the Fund may be invested in high yield debt instruments of foreign
issuers. The Fund will provide shareholders with at least 60 days' notice of any
change in the 80% policy.

Corporate debt securities in which the Fund invests are typically unsecured,
with a fixed-rate of interest, and are usually issued by companies or similar
entities to provide financing for their operations, or other activities. Bank
loans (which may commonly be referred to as "floating rate loans"), which are
another form of financing, are typically secured, with interest rates that
adjust or "float" periodically (normally on a daily, monthly, quarterly or
semiannual basis by reference to a base lending rate, such as LIBOR (London
Interbank Offered Rate), plus a premium). Secured debt instruments are
ordinarily secured by specific collateral or assets of the issuer or borrower
such that holders of these instruments will have claims senior to the claims of
other parties who hold unsecured instruments.

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

- - Reviewing interest rate and economic forecasts.

- - Reviewing credit characteristics and capital structures of companies,
  including an evaluation of any outstanding bank loans or corporate debt
  securities a company has issued, its relative position in its industry, and
  its management team's capabilities.


                                       59



- - Identifying companies that:

  - have medium and low quality ratings or, in the investment manager's opinion,
    have similar qualities to companies with medium or low quality ratings, even
    though they are not rated, or have been given a different rating by a rating
    agency,

  - have growth potential, or

  - have the potential to increase in value as their credit ratings improve.

- - Buying debt instruments that are expected to outperform other debt
  instruments.

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

- - The interest rate or economic outlook changes.

- - A sector or industry is experiencing change.

- - A security's rating is changed.

- - The security is overvalued relative to alternative investments.

- - The company no longer meets the investment manager's performance expectations.

- - The investment manager wishes to lock in profits.

- - The investment manager identifies a more attractive opportunity.

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

For bank loans, the investment manager's process includes a review of the legal
documentation supporting the loan, including an analysis of the covenants and
the rights and remedies of the lender.

The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, in an effort to produce
incremental earnings, to hedge existing positions, to increase market exposure
and investment flexibility, or to obtain or reduce credit exposure.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

For purposes of this discussion, a "fundamental" investment policy is one that
may not be changed without a shareholder vote. The Funds' fundamental investment
policies are set forth below:

                       underwriter under the 1933 Act in          be deemed to be an underwriter when it

COMPARISON OF NONFUNDAMENTAL POLICIES AND RELATED INVESTMENT STRATEGIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies of the Buying Fund. RiverSource Investments
does not believe that the differences between the nonfundamental policies of the
Funds result in any material differences in the way the Funds have been managed
or in the way the combined Fund will be managed.

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



COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives and principal investment strategies.
The actual risks of investing in each Fund depend on the securities held in each
Fund's portfolio and on market conditions, both of which change over time. Both
Funds are subject to the principal investment risks described below.

- - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers 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.

- - CREDIT RISK. Credit risk is the risk that the borrower of a loan or the issuer
  of another debt instrument will default or otherwise become unable or
  unwilling to honor a financial obligation, such as payments due on a loan.
  Rating agencies assign credit ratings to certain loans and other debt
  securities to indicate their credit risk. The price of a loan or other debt
  security generally will fall if the borrower or the issuer defaults on its
  obligation to pay principal or interest, the rating agencies downgrade the
  borrower's or the issuer's credit rating or other news affects the market's
  perception of the borrower's or the issuer's credit risk. If the borrower of a
  floating rate loan declares or is declared bankrupt, there may be a delay
  before the Fund can act on the collateral securing the loan, which may
  adversely affect the Fund. Further, here is a risk that a court could take
  action with respect to a floating rate loan adverse to the holders of the
  loan, such as invalidating the loan, the lien on the collateral, the priority
  status of the loan, or ordering the refund of interest previously paid by the
  borrower. Any such actions by a court could adversely affect the Fund's
  performance. If the Fund purchases unrated loans or other debt securities, or
  if the rating of a loan or security is reduced after purchase, the Fund will
  depend on the investment manager's analysis of credit risk more heavily than
  usual. Non-investment grade loans or securities, commonly called high yield or
  junk, may react more to perceived changes in the ability of the borrower or
  issuing entity to pay interest and

                                       62



  principal when due than to changes in interest rates. Non-investment grade
  loans or securities have greater price fluctuations and are more likely to
  experience a default than investment grade loans or securities. A default or
  expected default of a floating rate loan could also make it difficult for the
  Fund to sell the loan at a price approximating the value previously placed on
  it.

- - HIGHLY LEVERAGED TRANSACTIONS RISK. The high yield debt instruments in which
  the Fund invests substantially consist of transactions involving refinancings,
  recapitalizations, mergers and acquisitions and other financings for general
  corporate purposes. The Fund's investments also may include senior obligations
  of a borrower issued in connection with a restructuring pursuant to Chapter 11
  of the U.S. Bankruptcy Code (commonly known as "debtor-in-possession"
  financings), provided that such senior obligations are determined by the
  Fund's investment manager upon its credit analysis to be a suitable investment
  by the Fund. In such highly leveraged transactions, the borrower assumes large
  amounts of debt in order to have the financial resources to attempt to achieve
  its business objectives. Such business objectives may include but are not
  limited to: management's taking over control of a company (leveraged buy-out);
  reorganizing the assets and liabilities of a company (leveraged
  recapitalization); or acquiring another company. Loans or securities that are
  part of highly leveraged transactions involve a greater risk (including
  default and bankruptcy) than other investments.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  hedging risk, correlation risk, liquidity risk and leverage risk.

  Hedging risk is the risk that derivative instruments used to hedge against an
  opposite position may offset losses, but they may also offset gains.

  Correlation risk is related to hedging risk and is the risk that there may be
  an incomplete correlation between the hedge and the opposite position, which
  may result in increased or unanticipated losses.

  Liquidity risk is the risk that the derivative instrument may be difficult or
  impossible to sell or terminate, which may cause the Fund to be in a position
  to do something the investment manager would not otherwise choose, including
  accepting a lower price for the derivative instrument, selling other
  investments or foregoing another, more appealing investment opportunity.

  Leverage risk is the risk that losses from the derivative instrument may be
  greater than the amount invested in the derivative instrument. Certain
  derivatives have the potential for unlimited losses, regardless of the size of
  the initial investment.

- - INTEREST RATE RISK. The securities in the Fund are subject to the risk of
  losses attributable to changes in interest rates. Interest rate risk is
  generally associated with the fixed-income securities in the Fund: when
  interest rates rise, the prices of fixed-income securities generally fall. In
  general, the longer the maturity or duration of a fixed-income security, the
  greater its sensitivity to changes in interest rates. Securities with floating
  interest rates can be less sensitive to interest rate changes, but may decline
  in value if their interest rates do not rise as much as interest rates in
  general. Because rates on certain floating rate loans and other debt
  securities reset only periodically, changes in prevailing interest rates (and
  particularly sudden and significant changes) can be expected to cause
  fluctuations in the Fund's net asset value. Interest rate changes also may
  increase prepayments of debt obligations, which in turn would increase
  prepayment risk.

- - LIQUIDITY RISK. Liquidity risk is the risk associated from a lack of
  marketability of securities which may make it difficult or impossible to sell
  the security at desirable prices in order to minimize loss. The Fund may have
  to lower the selling price, sell other investments, or forego another, more
  appealing investment opportunity. Floating rate loans generally are subject to
  legal or contractual restrictions on resale. Floating rate loans also may
  trade infrequently on the secondary market. The value of the loan to the Fund
  may be impaired in the event that the Fund needs to liquidate such loans.
  Other debt securities in which the Fund invests may be traded in the over-the
  counter market rather than on an organized exchange and therefore may be more
  difficult to purchase or sell at a fair price. The inability to purchase or
  sell floating rate loans and other debt securities at a fair price may have a
  negative impact on the Fund's performance.

- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably.

- - PREPAYMENT AND EXTENSION RISK. Prepayment and extension risk is the risk that
  a loan, bond or other security might be called or otherwise converted, prepaid
  or redeemed before maturity. This risk is primarily associated with asset-
  backed securities, including mortgage backed securities and floating rate
  loans. If a loan or security is converted, prepaid or redeemed before
  maturity, particularly during a time of declining interest rates or declining
  spreads, the portfolio managers

                                       63



  may not be able to reinvest the prepayment proceeds in securities or loans
  providing as high a level of income, resulting in a reduced yield to the Fund.
  Conversely, as interest rates rise or spreads widen, the likelihood of
  prepayment decreases. The portfolio managers may be unable to capitalize on
  securities with higher interest rates or wider spreads because the Fund's
  investments are locked in at a lower rate for a longer period of time.

- - FOREIGN/EMERGING MARKETS RISK. The following are all components of
  foreign/emerging markets risk:

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

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

  Custody risk refers to the process of clearing and settling trades. It also
  covers holding securities with local agents and depositories. Low trading
  volumes and volatile prices in less developed markets make trades harder to
  complete and settle. Local agents are held only to the standard of care of the
  local market. Governments or trade groups may compel local agents to hold
  securities in designated depositories that are not subject to independent
  evaluation. The less developed a country's securities market is, the greater
  the likelihood of problems occurring.

  Emerging markets risk includes the dramatic pace of change (economic, social
  and political) in these countries as well as the other considerations listed
  above. These markets are in early stages of development and are extremely
  volatile. They can be marked by extreme inflation, devaluation of currencies,
  dependence on trade partners and hostile relations with neighboring countries.

- - COUNTERPARTY RISK. Counterparty risk is the risk that a counterparty to a
  financial instrument entered into by the Fund or held by a special purpose or
  structured vehicle becomes bankrupt or otherwise fails to perform its
  obligations due to financial difficulties. The Fund may experience significant
  delays in obtaining any recovery in a bankruptcy or other reorganization
  proceeding. The Fund may obtain only limited recovery or may obtain no
  recovery in such circumstances. The Fund will typically enter into financial
  instrument transactions with counterparties whose credit rating is investment
  grade, or, if unrated, determined to be of comparable quality by the
  investment manager.

- - IMPAIRMENT OF COLLATERAL RISK. The value of collateral, if any, securing a
  floating rate loan can decline, and may be insufficient to meet the borrower's
  obligations or difficult to liquidate. In addition, the Fund's access to
  collateral may be limited by bankruptcy or other insolvency laws. Further,
  certain floating rate loans may not be fully collateralized and may decline in
  value.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- - how each Fund's average annual total returns compare to indexes shown in the
  table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How the Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Class A, Class B, Class C, Class R and Class I shares of Seligman High-Yield
Fund. The second table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class R2 and Class R5 shares of the RiverSource High
Yield Bond Fund. These returns are compared to the indexes shown for the same
periods. For purposes of the performance calculation in the table we assumed:

- - the maximum sales charge of 4.50% for Class A shares of the Selling Fund* and
  4.75% for Class A shares of the Buying Fund;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B, Class C** and Class R shares;

- - no sales charge for Class R2, Class R5 and Class I shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

     * Effective Jan. 7, 2008, the maximum initial sales charge in Class A
       shares of the Selling Fund is 4.50%. Although for all periods presented
       the Selling Fund's Class A share returns reflect the 4.50% maximum
       initial sales charge, the actual returns for periods prior to Jan. 7,
       2008 would have been lower if a 4.75% maximum initial sales charge then
       in effect was incurred.

    ** Effective June 4, 2007, there is no initial sales charge on purchases of
       Class C shares of the Selling Fund. Although for all periods presented
       the Selling Fund's Class C share returns do not reflect an initial sales
       charge, the actual returns for periods prior to June 4, 2007 would have
       been lower if a 1.00% maximum initial sales charge then in effect was
       incurred.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

fund with an identical investment objective and investment strategies. As of
Oct. 18, 2005, the Buying Fund became a stand-alone fund that invests directly
in a portfolio of securities. The information shown in the table and in the
financial highlights for the Buying Fund includes the activity of the Buying
Fund when it was a feeder in a master/feeder arrangement.

     Index, which will be used as the primary benchmark for the Fund going
     forward.

The JP Morgan Global High Yield Index is an unmanaged index used to mirror the
investable universe of the U.S. dollar global high yield corporate debt market
of both developed and emerging markets. The index reflects reinvestment of all
distributions and changes in market prices and reflects no deduction for fees,
expenses or taxes.

The Barclays Capital U.S. Corporate High-Yield 2% Issuer Capped Index, an
unmanaged index, covers the U.S. corporate bond market of high-yield bonds
denominated in U.S. dollars, and is constrained from having greater than 2% of
the securities of a single issuer. The index reflects reinvestment of all
distributions and changes in market prices and reflects no deduction for fees,
expenses or taxes.

The Lipper High Current Yield Funds Average is an average of funds that aim at
high (relative) current yield from fixed income securities, have no quality or
maturity restrictions, and tend to invest in lower-grade debt instruments. The
average is an unmanaged benchmark that assumes reinvestment of all
distributions, if any, and excludes the effect of fees, taxes and sales charges.

The Lipper High Current Yield Bond Funds Index includes the 30 largest high
yield bond funds tracked by Lipper Inc. The index's returns include net
reinvested dividends.

Investors cannot invest directly in an average or index.

PROPOSAL 5. REORGANIZATION OF SELIGMAN INCOME AND GROWTH FUND INTO RIVERSOURCE
BALANCED FUND

COMPARISON OF INVESTMENT OBJECTIVES

Each Fund generally seeks a combination of capital appreciation and current
income.

The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman Income and Growth Fund seeks total return
                        through a combination of capital appreciation and income
                        consistent with what is believed to be a prudent
                        allocation between equity and fixed-income securities.

          BUYING FUND: RiverSource Balanced Fund seeks to provide shareholders
                       with a balance of growth of capital and current income.

Because any investment involves risk, there is no assurance the Fund's objective
can be achieved. Only shareholders can change the Fund's objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests predominantly in a combination of equity and fixed-income
securities. The Selling Fund may invest 10% of its assets in equity-linked
securities (each, an "ELS"). The Buying Fund has no similar restriction with
respect to investments in ELSs. The Selling Fund may invest up to 10% of total
assets in foreign securities; the Buying Fund may invest up to 25% of the Fund's
net assets in foreign investments. The Buying Fund counts American Depositary
Receipts ("ADRs") toward its 25% limit, but ADRs are excluded from the Selling
Fund's 10% limitation.

DETAILED STRATEGIES FOR THE SELLING FUND AND THE BUYING FUND ARE SET FORTH
BELOW:

SELIGMAN INCOME AND GROWTH FUND (SELLING FUND)

The Fund allocates its assets between equity securities and fixed-income
securities. Securities are carefully selected in light of the Fund's investment
objective and are diversified among many different types of securities and
market sectors. As of Dec. 31, 2008, approximately 67% of the Fund's portfolio
was invested in equity securities and approximately 33% was invested in fixed-
income securities. However, the proportion of the Fund's assets invested in each
type of security will vary from time to time based on the investment manager's
assessment of general market and economic conditions.

EQUITY SECURITIES

Equity securities in which the Fund may invest include: common stocks, including
real estate investment trusts ("REITs"); securities convertible into common
stocks; preferred stocks; and ADRs. The Fund usually invests in the common stock
of larger U.S. companies; however, it may invest in companies of any size. REITs
are companies that invest primarily in income-producing real estate or real
estate related loans or interests. ADRs are publicly traded instruments
generally issued by domestic banks or trust companies that represent securities
of foreign issuers.

Equity securities are chosen using an investment philosophy rooted in the belief
that a disciplined, systematic, value-oriented approach to investing primarily
in large-cap companies provides investors with an excellent opportunity for
long-term growth of capital.

In pursuit of the Fund's objective, RiverSource Investments chooses equity
investments by seeking to:

- - Select companies that are undervalued based on a variety of measures,
  including, but not limited to price-to-earnings ratios, price-to-book ratios,
  price-to-free cash flow, current and projected dividends, sum-of-the parts or
  breakup value and historic relative price valuations.

- - Identify companies with moderate growth potential based on:

  - effective management, as demonstrated by overall performance;

  - financial strength; and

  - underappreciated potential for improvement in industry and thematic trends.

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

- - The security is overvalued relative to alternative investments.

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

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

- - The security exhibits unacceptable correlation characteristics with other
  portfolio holdings.

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


                                       69



FIXED-INCOME SECURITIES

Investment grade fixed-income securities are those rated within the four highest
rating categories by Moody's Investors Service ("Moody's"), Standard & Poor's
Rating Services ("S&P") or Fitch Ratings, or are securities deemed by the
investment manager to be of comparable quality (collectively, "Investment Grade
Securities"). They include obligations issued and guaranteed by the U.S.
government or its agencies or instrumentalities, corporate bonds and other
obligations, mortgage-backed and other asset-backed securities, obligations of
non-U.S. government agencies and private institutions, and income-producing cash
equivalents, including repurchase agreements. Mortgage-backed securities include
collateralized mortgage obligations, mortgage pass-through securities and
stripped mortgage-backed securities.

Although the Fund emphasizes high- and medium-quality debt securities, it may
assume some credit risk in an effort to achieve higher yield and/or capital
appreciation by buying lower-quality (junk) bonds which carry non-investment
grade ratings (Ba or below by Moody's or BB or below by Fitch Ratings or S&P) or
are securities deemed to be below investment grade by the investment manager
("High-Yield Securities"). Although High Yield Securities have the potential to
offer higher yields than Investment Grade Securities with higher ratings and
similar maturities, High Yield Securities are subject to greater risk of loss of
principal and interest than Investment Grade Securities. The Fund may invest in
all types of High Yield Securities including:

- - Senior and subordinated corporate debt obligations of both U.S. and non-U.S.
  issuers (including, for example, debentures, loan participations and floating
  rate loans);

- - Mortgage and other asset-backed securities;

- - Capital appreciation bonds, including zero coupon and pay-in-kind securities;

- - Convertible securities, preferred stock, structured securities and loan
  participations;

- - Municipal securities;

- - Obligations of foreign governments;

- - Securities that are rated in default by a nationally recognized statistical
  rating organization;

- - Repurchase agreements relating to the above instruments;

- - Warrants, rights and other equity securities that are acquired in connection
  with the Fund's investments in High Yield Securities; and

- - Restricted securities that may be offered and sold only to "qualified
  institutional buyers" under Rule 144A of the Securities Act of 1933 ("Rule
  144A Securities").

The Fund does not have any portfolio maturation limitation, and may invest its
assets in High Yield Securities of short, medium or long maturities.

Investment Grade Securities. In pursuit of the Fund's objective, the investment
manager chooses Investment Grade Securities by:

- - Evaluating the Investment Grade Securities portion of the portfolio's total
  exposure to sectors, industries and securities relative to the Barclays
  Capital U.S. Aggregate Bond Index (the "Barclays Index").

- - Analyzing factors such as credit quality, interest rate outlook and price in
  seeking to select the most attractive securities within each sector.

- - Targeting an average portfolio duration within one year of the duration of the
  Barclays Index which, as of Jan. 31, 2009, was 4.18 years. Duration measures
  the sensitivity of bond prices to changes in interest rates. The longer the
  duration of a bond, the longer it will take to repay the principal and
  interest obligations and the more sensitive it will be to changes in interest
  rates. For example, a five-year duration means a bond is expected to decrease
  in value by 5% if interest rates rise 1% and increase in value by 5% if
  interest rates fall 1%.

In evaluating whether to sell Investment Grade Securities, the investment
manager considers, among other factors:

- - Identification of more attractive investments based on relative value.

- - The portfolio's total Investment Grade Securities exposure to sectors,
  industries and securities relative to the Barclays Index.

- - Whether a security's rating has changed or is vulnerable to a change.

- - Whether a sector or industry is experiencing change.

- - Changes in the interest rate or economic outlook.

High-Yield Securities. In pursuit of the Fund's objective, the investment
manager chooses High Yield Securities by:

- - Reviewing interest rate and economic forecasts.


                                       70





- - Reviewing credit characteristics and capital structures of companies,
  including an evaluation of any outstanding bank loans or corporate debt
  securities a company has issued, its relative position in its industry, and
  its management team's capabilities.

- - Identifying companies that:

  - have medium and low quality ratings or, in the investment manager's opinion,
    have similar qualities to companies with medium or low quality ratings, even
    though they are not rated, or have been given a different rating by a rating
    agency,

  - have growth potential, or

  - have the potential to increase in value as their credit ratings improve.

- - Buying debt instruments that are expected to outperform other debt
  instruments.

In evaluating whether to sell High Yield Securities, the investment manager
considers, among other factors, whether:

- - The interest rate or economic outlook changes.

- - A sector or industry is experiencing change.

- - A security's rating is changed.

- - The security is overvalued relative to alternative investments.

- - The company no longer meets the investment manager's performance expectations.

- - The investment manager wishes to lock in profits.

- - The investment manager identifies a more attractive opportunity.

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

OTHER STRATEGIES

The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold) including funding agreements issued by
domestic insurance companies and may invest up to 10% of its total assets
directly in foreign securities. The limit on foreign securities does not apply
to ADRs or commercial paper and certificates of deposit issued by foreign banks.

The Fund may also invest up to 10% of its assets in exchange-traded funds
("ETFs"). ETFs are traded, like individual stocks, on an exchange, but they
represent baskets of securities that seek to track the performance of certain
indices. The indices include not only broad-market indices but more specific
indices as well, including those relating to particular sectors, countries and
regions. The Fund may invest in ETFs for short-term cash management purposes or
as part of its overall investment strategy.

The Fund may also invest up to 10% of its assets in ELSs as part of its overall
investment strategy. An ELS is a debt instrument whose value is based on the
value of a single equity security, basket of equity securities or an index of
equity securities (each, an "Underlying Equity"). An ELS typically provides
interest income, thereby offering a yield advantage over investing directly in
an Underlying Equity. However, the holder of an ELS may have limited or no
benefit from any appreciation in the Underlying Equity, but is exposed to
downside market risk. The Fund may purchase ELSs that trade on a securities
exchange or those that trade on the over-the-counter markets, including Rule
144A Securities. The Fund may also purchase an ELS in a privately negotiated
transaction with the issuer of the ELS (or its broker-dealer affiliate).

RIVERSOURCE BALANCED FUND (BUYING FUND)

The Fund invests primarily in a combination of common and preferred stocks,
bonds and other debt securities. Under normal market conditions, at least 40% of
the Fund's total assets are invested in common stocks and no less than 25% of
the Fund's total assets are invested in debt securities. Equity securities may
provide income, offer the opportunity for long-term capital appreciation, or
both. The Fund can invest in any economic sector and, at times, it may emphasize
one or more particular sectors. Although the Fund emphasizes high- and medium-
quality securities for the debt portion of its portfolio, it may buy lower-
quality bonds (junk bonds). The Fund may invest up to 25% of its net assets in
foreign investments.

The Fund's equity investment philosophy is rooted in the belief that a
disciplined, systematic, value-oriented approach to investing primarily in
large-cap companies provides investors with an excellent opportunity for long-
term growth of capital.

In pursuit of the Fund's objective, RiverSource Investments chooses equity
investments by seeking to:

- - Select companies that are undervalued based on a variety of measures,
  including, but not limited to price-to-earnings ratios, price-to-book ratios,
  price-to-free cash flow, current and projected dividends, sum-of-the parts or
  breakup value and historic relative price valuations.


                                       71





- - Identify companies with moderate growth potential based on:

  - effective management, as demonstrated by overall performance;

  - financial strength; and

  - underappreciated potential for improvement in industry and thematic trends.

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

- - The security is overvalued relative to alternative investments.

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

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

- - The security exhibits unacceptable correlation characteristics with other
  portfolio holdings.

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

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

- - Evaluating the debt portion of the portfolio's total exposure to sectors,
  industries and securities relative to the Barclays Capital U.S. Aggregate Bond
  Index (the "Index").

- - Analyzing factors such as credit quality, interest rate outlook and price to
  select the most attractive securities within each sector.

- - Targeting an average duration for the debt portion of the portfolio within one
  year of the duration of the Index which, as of Jan. 31, 2009 was 4.18 years.
  Duration measures the sensitivity of bond prices to changes in interest rates.
  The longer the duration of a bond, the longer it will take to repay the
  principal and interest obligations and the more sensitive it will be to
  changes in interest rates. For example, a five-year duration means a bond is
  expected to decrease in value by 5% if interest rates rise 1% and increase in
  value by 5% if interest rates fall 1%.

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

- - The debt portion of the portfolio's total exposure to sectors, industries and
  securities relative to the Index.

- - Whether a security's rating is changed or is vulnerable to a change.

- - Whether a sector or industry is experiencing change.

- - Changes in the interest rate or economic outlook.

- - Whether the investment manager identifies a more attractive opportunity.

The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, in an effort to produce
incremental earnings, to hedge existing positions, to increase market exposure
and investment flexibility, or to obtain or reduce credit exposure.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

may not be changed without a shareholder vote. The Funds' fundamental investment

COMPARISON OF NONFUNDAMENTAL POLICIES AND RELATED INVESTMENT STRATEGIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies of the Buying Fund. RiverSource Investments

or in the way the combined Fund will be managed.

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives, principal investment strategies and
investment policies. With regards to investment policies, although the
investment policies of the Buying Fund and the Selling Fund are similar with
regards to high yield (junk) bonds, the Buying Fund currently has greater
exposure to high yield (junk) bonds than the Selling Fund resulting in greater
current credit and liquidity risk to its shareholders. The actual risks of
investing in each Fund depend on the securities held in each Fund's portfolio
and on market conditions, both of which change over time. Both Funds are subject
to the principal investment risks described below.


                                       74





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

- - CREDIT RISK. Credit risk is the risk that the issuer of a security, or the
  counterparty to a contract, will default or otherwise become unable or
  unwilling to honor a financial obligation, such as payments due on a bond or a
  note. If the Fund purchases unrated securities, or if the rating of a security
  is reduced after purchase, the Fund will depend on the investment manager's
  analysis of credit risk more heavily than usual. Non-investment grade
  securities, commonly called high yield or junk bonds, may react more to
  perceived changes in the ability of the issuing entity to pay interest and
  principal when due than to changes in interest rates. Non-investment grade
  securities have greater price fluctuations and are more likely to experience a
  default than investment grade bonds.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  correlation risk, counterparty credit risk, hedging risk and leverage risk.

  Correlation risk is related to hedging risk and is the risk that there may be
  an incomplete correlation between the hedge and the opposite position, which
  may result in increased or unanticipated losses.

  Counterparty credit risk is the risk that a counterparty to the derivative
  instrument becomes bankrupt or otherwise fails to perform its obligations due
  to financial difficulties, and the Fund may obtain no recovery of its
  investment or may only obtain a limited recovery, and any recovery may be
  delayed.

  Hedging risk is the risk that derivative instruments used to hedge against an
  opposite position may offset losses, but they may also offset gains.

  Leverage risk is the risk that losses from the derivative instrument may be
  greater than the amount invested in the derivative instrument.

- - RISKS OF FOREIGN INVESTING. Foreign securities are securities of issuers based
  outside the United States. An issuer is deemed to be based outside the United
  States if it is organized under the laws of another country. Foreign
  securities are primarily denominated in foreign currencies. In addition to the
  risks normally associated with domestic securities of the same type, foreign
  securities are subject to the following foreign risks:

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

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

  Custody risk refers to the process of clearing and settling trades. It also
  covers holding securities with local agents and depositories. Low trading
  volumes and volatile prices in less developed markets make trades harder to
  complete and settle. Local agents are held only to the standard of care of the
  local market. Governments or trade groups may compel local agents to hold
  securities in designated depositories that are not subject to independent
  evaluation. The less developed a country's securities market is, the greater
  the likelihood of problems occurring.

- - INTEREST RATE RISK. Interest rate risk is the risk of losses attributable to
  changes in interest rates. Interest rate risk is generally associated with
  bond prices: when interest rates rise, bond prices fall. In general, the
  longer the maturity or duration of a bond, the greater its sensitivity to
  changes in interest rates.

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

- - LIQUIDITY RISK. The risk associated from a lack of marketability of securities
  which may make it difficult or impossible to sell at desirable prices in order
  to minimize loss. The Fund may have to lower the selling price, sell other
  investments, or forego another, more appealing investment opportunity.


                                       75





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

- - PREPAYMENT AND EXTENSION RISK. Prepayment and extension risk is the risk that
  a bond or other security might be called or otherwise converted, prepaid, or
  redeemed before maturity. This risk is primarily associated with asset-backed
  securities, including mortgage-backed securities. If a security is converted,
  prepaid, or redeemed before maturity, particularly during a time of declining
  interest rates, the investment manager may not be able to reinvest in
  securities providing as high a level of income, resulting in a reduced yield
  to the Fund. Conversely, as interest rates rise, the likelihood of prepayment
  decreases. The investment manager may be unable to capitalize on securities
  with higher interest rates because the Fund's investments are locked in at a
  lower rate for a longer period of time.

- - SECTOR RISK. If a fund emphasizes one or more economic sectors, it may be more
  susceptible to the financial, market or economic events affecting the
  particular issuers and industries in which it invests than funds that do not
  emphasize particular sectors. The more a fund diversifies, the more it spreads
  risk and potentially reduces the risks of loss and volatility.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- - how each Fund's average annual total returns compare to indexes shown in the
  table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts. If sales charges
were included, the returns would be lower.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class R and Class I shares of Seligman Income and
Growth Fund. The second table shows total returns from hypothetical investments
in Class A, Class B and Class C shares of the RiverSource Balanced Fund. The
inception date for Class R2 and Class R5 of the Buying Fund is expected to be in
the third quarter of 2009 and therefore performance information for those
classes is not shown. These returns are compared to the indexes shown for the
same periods. For purposes of the performance calculation in the table we
assumed:

- - the maximum sales charge of 5.75%* for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B, Class C** and Class R shares;

- - no sales charge for Class I shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

   * Effective Jan. 7, 2008, the maximum initial sales charge on investments in
     Class A shares of the Selling Fund is 5.75%. Although for all periods
     presented, the Selling Fund's Class A share returns reflect the 5.75%
     maximum initial sales charge, the actual returns for periods prior to Jan.
     7, 2008 would have been higher if a 4.75% maximum initial sales charge then
     in effect was incurred.

  ** Effective June 4, 2007, there is no initial sales charge on purchases of
     Class C shares of the Selling Fund. Although for all periods presented in
     the tables the Selling Funds' Class C share returns do not reflect an
     initial sales charge, the actual returns for periods prior to June 4, 2007
     would have been lower if a 1.00% maximum initial sales charge then in
     effect was incurred.


                                       76



AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

The Buying Fund formerly was a "feeder" fund in a master/feeder arrangement
where the Buying Fund invested all of its assets in a corresponding "master"
fund with an identical investment objective and investment strategies. As of
Jan. 12, 2006, the Buying Fund became a stand-alone fund that invests directly
in a portfolio of securities. The information shown in the table and in the
financial highlights for the Buying Fund includes the activity of the Buying
Fund when it was a feeder in a master/feeder arrangement.

  ***Effective Nov. 7, 2008, to better align the primary benchmark index with

The S&P 500 Index, an unmanaged index, measures the performance of 500 of the
largest U.S. companies based on market capitalization. The index reflects
reinvestment of all distributions and changes in market prices and reflects no
deduction for fees, expenses or taxes.

The Barclays Capital U.S. Aggregate Bond Index, an unmanaged index, is made up
of a representative list of government, corporate, asset-backed and mortgage
backed securities. The index is frequently used as a general measure of bond
market performance. The index reflects reinvestment of all distributions and
changes in market prices and reflects no deduction for fees, expenses or taxes.

The Barclays Capital U.S. Government/Credit Index, an unmanaged index, is
comprised of all bonds that are investment grade (rated Baa or higher by Moody's
or BBB or higher by S&P, if unrated by Moody's) with at least one year to
maturity. The index reflects reinvestment of all distributions and changes in
market prices and reflects no deduction for fees, expenses or taxes.

The Blended Index is comprised of a 60% weighting in the Russell 1000 Value
Index and 40% in the Barclays Capital U.S. Aggregate Bond Index. The index is an
unmanaged benchmark that reflects reinvestment of all distributions and changes
in market prices and reflects no deduction for fees, expenses or taxes.

The Blended Index (Selling Fund old) is comprised of a 60% weighting in the S&P
500 Index and a 40% weighting in the Barclays Capital U.S. Government/Credit
Index. The index is an unmanaged benchmark that reflects reinvestment of all
distributions and changes in market prices and reflects no deduction for fees,

The Lipper Mixed-Asset Target Allocation Growth Funds Average measures the
performance of funds, that by portfolio practice, maintain a mix of between 60%-
80% equity securities, with the remainder invested in bonds, cash and cash
equivalents. The average is an unmanaged benchmark that assumes the reinvestment
of all distributions, if any, and does not reflect any fees, sales charges or
taxes.

The Lipper Balanced Funds Index includes the 30 largest balanced funds tracked
by Lipper Inc. The index's returns include net reinvested dividends. The Buying
Fund's performance is currently measured against this index for purposes of
determining the performance incentive adjustment. See Fund Management and
Compensation in Exhibit B for more information.

Investors cannot invest directly in an average or index.

The inception date for Class R2 and Class R5 of the Buying Fund is expected to
be in the third quarter of 2009 and therefore performance information for those
classes is not shown.

PROPOSAL 6. REORGANIZATION OF SELIGMAN INTERNATIONAL GROWTH FUND INTO
RIVERSOURCE PARTNERS INTERNATIONAL SELECT GROWTH FUND

COMPARISON OF INVESTMENT OBJECTIVES

Each Fund seeks long-term capital appreciation and invests predominantly in
equity securities of foreign issuers that are believed to be growth companies.

The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman International Growth Fund seeks long-term
                        capital appreciation.

          BUYING FUND: RiverSource Partners International Select Growth Fund
                       seeks to provide shareholders with long-term capital
                       growth.

Because any investment involves risk, there is no assurance the Fund's objective
can be achieved. Only shareholders can change the Fund's objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund may invest in common stock of companies in any country. However, the
Selling Fund typically will not invest in companies located in the United
States. The Buying Fund's assets are primarily invested in equity securities of
foreign issuers. The Selling Fund may invest up to 25% of its assets in
preferred stock and investment-grade or comparable quality debt securities and
generally invests less than 25% of its assets in emerging markets, while the
Buying Fund has no similar restrictions. Both Funds may use forward foreign
currency exchange contracts or purchase put options as part of their principal
investment strategies.

RiverSource Investments serves as the investment manager for each Fund and is
responsible for the oversight of each Fund's subadviser(s) which provide day-to-
day management of the Fund. The Selling Fund is subadvised by Wellington and the
Buying Fund is subadvised by Columbia Wanger Asset Management, L.P. ("Columbia
WAM") and Principal Global Investors, LLC ("Principal Global") (collectively,
the "Subadvisers").

DETAILED STRATEGIES FOR THE SELLING FUND AND THE BUYING FUND ARE SET FORTH
BELOW:

SELIGMAN INTERNATIONAL GROWTH FUND (SELLING FUND)

The Fund invests primarily in high quality, large- and mid capitalization growth
companies ($1 billion or more at the time of initial purchase by the Fund) that
are considered leaders in their industries, emphasizing those industries that
are growing on a global basis. The Fund may invest in any country; however, it
typically will not invest in the United States. It generally invests in several
countries in different geographic regions.

The Fund generally invests in the common stock of medium- to large- sized
companies in the principal international markets. However, it may also invest in
companies with a lower market capitalization or in smaller regional or emerging
markets (representation in the emerging markets will generally be less than 25%
of assets).

In selecting individual securities, the portfolio manager looks to identify
companies that it believes display one or more of the following:

- - Attractive valuations relative to earnings and revenue forecasts or other
  valuation criteria (e.g., return on equity)

- - Quality management

- - Unique competitive advantages (e.g., market share, proprietary products)

- - Strong possibility of multiple expansion

- - Potential for improvement in overall operations (hidden/unappreciated value)

The Fund generally sells a stock if the portfolio manager believes its target
price has been reached, there is a decelerating trend of earnings growth,
deteriorating industry fundamentals, management change or failure, its revenue
growth has slowed, or its underlying fundamentals have deteriorated.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the U.S. dollar. The securities may be
listed on a U.S. or foreign stock exchange or traded in U.S. or foreign over-
the-counter markets. The Fund normally concentrates its investments in common
stocks; however, it may invest in other types of equity securities, including
securities convertible into or exchangeable for common stock, depositary
receipts, and rights and warrants to purchase common stock. The Fund also may
invest up to 25% of its assets in preferred stock and investment-grade or
comparable quality debt securities. The Fund may invest up to 15% of its net
assets in illiquid securities (i.e., securities that cannot be readily sold),
and may from time to time enter into forward foreign currency exchange contracts
in an attempt to manage the risk of adverse changes in currencies. The Fund may
also purchase put options in an attempt to hedge against a

                                       80



decline in the price of securities it holds in its portfolio. A put option gives
the Fund the right to sell an underlying security at a particular price during a
fixed period of time. Forward foreign currency exchange contracts and put
options on securities may not be available to the Fund on reasonable terms in
many situations, and the Fund may frequently choose not to enter into such
contracts or purchase such options even when they are available.

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 may also invest up to 10% of its assets in exchange-traded funds
("ETFs"). ETFs are traded, like individual stocks, on an exchange, but they
represent baskets of securities that seek to track the performance of certain
indices. The indices include not only broad-market indices but more specific
indices as well, including those relating to particular sectors, countries and
regions. The Fund may invest in ETFs for short-term cash management purposes or
as part of its overall investment strategy.

RIVERSOURCE PARTNERS INTERNATIONAL SELECT GROWTH FUND (BUYING FUND)

The Fund's assets are primarily invested in equity securities of foreign issuers
that are believed to offer strong growth potential. The Fund may invest in both
developed and emerging markets.

RiverSource Investments serves as the investment manager to the Fund and is
responsible for the oversight of the Fund's Subadvisers, who provide day-to-day
management for the Fund. Each of the Subadvisers acts independently of the other
and uses its own methodology for selecting investments. RiverSource Investments,
subject to the oversight of the Fund's Board of Directors (Board), decides the
proportion of the Fund assets to be managed by each subadviser, and may change
these proportions at any time. RiverSource Investments currently intends to
allocate a majority of the Fund's assets to Principal Global, although this
could change. Each of the Subadvisers employs an active investment strategy that
focuses on companies that the Subadvisers believe will increase in value over
time.

COLUMBIA WAM

Columbia WAM invests primarily in stocks of small- and medium sized companies
based both outside and in the U.S. with capitalizations of less than $5 billion
at the time of purchase. As long as the stock continues to meet the Fund's other
investment criteria, Columbia WAM may choose to hold the stock even if it grows
beyond that capitalization limit. Columbia WAM believes that smaller
companies -- particularly outside the U.S. -- which are not as well known by
financial analysts and which dominate a part of the market may offer higher
return potential than the stocks of larger companies. Columbia WAM invests in
the stocks of foreign companies based in developed markets and also emerging
markets.

In making investments for the Fund, Columbia WAM typically looks for companies
with:

- - A strong business franchise that offers growth potential.

- - Products and services that give a company a competitive advantage.

- - A stock price that Columbia WAM believes is reasonable relative to the assets
  and earning power of the company.

Columbia WAM relies primarily on independent, internally generated research to
uncover companies that may be less well known than the more popular names. To
find these companies, Columbia WAM looks for growth potential, financial
strength, and fundamental value. Columbia WAM may identify what it believes are
important economic, social, or technological trends (for example, the growth of
outsourcing as a business strategy, or the productivity gains from the
increasing use of technology) and try to identify companies it thinks will
benefit from these trends.

</Table>


Columbia WAM believes that if the growth potential is realized, it may provide a
basis for the company to outperform its peers. A strong balance sheet gives
management greater flexibility to pursue strategic objectives and is essential
to maintaining

                                       81



a competitive advantage. Once Columbia WAM uncovers an attractive company, it
identifies a price that it believes would also make the stock a good value.

Columbia WAM may use foreign currency futures contracts or foreign currency
forward contracts, with terms of up to one year in an effort to hedge existing
positions, interest rate fluctuations or currency fluctuations. Columbia WAM
also may purchase foreign currency for immediate settlement in order to purchase
foreign securities.

PRINCIPAL GLOBAL

Principal Global's equity investment philosophy is based on the belief that
superior stock selection and disciplined risk management provide consistent
outperformance. Principal Global focuses on companies with improving and
sustainable business fundamentals, rising investor expectations and attractive
relative valuations. To support their stock selection skills, which are believed
to be the primary drivers of relative performance, Principal Global seeks to
leverage technology in a research-driven approach and neutralize unintended
portfolio risks.

Principal Global selects securities for the Fund based on its own global
investment research. The research process is comprised of the following
components:

- - A proprietary and customized information management and screening framework,
  providing high-quality, real-time breadth of research coverage and peer
  rankings encompassing more than 10,000 companies worldwide.

- - A systematic evaluation of companies based on objective measures such as
  accelerating profitability, discounted cash flow valuation and market
  confirmation.

- - The portfolio managers and research analysts team working together to build
  systematic quantitative fundamental models that reflect the critical drivers
  of performance.

These models produce relative rankings for each stock within their appropriate
peer group that differentiate the most attractive from the least attractive
stocks. Stocks that appear to be attractive based on initial screening and
analysis are subjected to more rigorous examination by the research analysts.
The analysts then seek to validate or confirm the attractive characteristics
identified by the research process, as well as apply more qualitative analysis
to issues such as evaluating the sustainability of fundamental changes. As part
of the research process, the research analysts meet with company management,
conduct on-site due diligence visits, attend industry conferences, as well as
interact with sell-side equity analysts on a daily basis.

Principal Global's stock selection process is complemented by disciplined
portfolio risk controls. The portfolio risk management ensures any excess
returns come from stock selection skills and not from influences such as large
sector or country exposures. This is designed to enhance the consistency of
Principal Global's investment process and to minimize the risk of unexpected
negative surprises.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

For purposes of this discussion, a "fundamental" investment policy is one that
may not be changed without a shareholder vote. The Funds' fundamental investment
policies are set forth below:

COMPARISON OF NONFUNDAMENTAL POLICIES AND RELATED INVESTMENT STRATEGIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies of the Buying Fund. RiverSource Investments
does not believe that the differences between the nonfundamental policies of the

or in the way the combined Fund will be managed.

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives, principal investment strategies and
investment policies. Because the Buying Fund invests primarily in small- and
medium-sized companies whereas the Selling Fund invests primarily in medium- to
large-sized companies, the Buying Fund is subject to greater small-sized company
risk. With regards to investment policies, the Buying Fund may expose
shareholders to greater emerging markets risk due to the Buying Fund's greater
ability to invest in emerging market securities. The Buying Fund may also expose
shareholders to greater issuer risk and market risk due to the Buying Fund's
greater ability to invest in preferred stock and debt securities. The actual
risks of investing in each Fund depend on the securities held in each Fund's
portfolio and on market conditions, both of which change over time. Both Funds
are subject to the principal investment risks described below.

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

- - RISKS OF FOREIGN INVESTING. Foreign securities are securities of issuers based
  outside the United States. An issuer is deemed to be based outside the United
  States if it is organized under the laws of another country. Foreign
  securities are primarily denominated in foreign currencies. In addition to the
  risks normally associated with domestic securities of the same type, foreign
  securities are subject to the following foreign risks:

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

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

 Custody risk refers to the process of clearing and settling trades. It also
 covers holding securities with local agents and depositories. Low trading
 volumes and volatile prices in less developed markets make trades harder to
 complete and settle. Local agents are held only to the standard of care of the
 local market. Governments or trade groups may compel local agents to hold
 securities in designated depositories that are not subject to independent
 evaluation. The less developed a country's securities market is, the greater
 the likelihood of problems occurring.

 Emerging markets risk includes the dramatic pace of change (economic, social
 and political) in these countries as well as the other considerations listed
 above. These markets are in early stages of development and are extremely
 volatile. They can be marked by extreme inflation, devaluation of currencies,
 dependence on trade partners, and hostile relations with neighboring countries.

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

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

- - SECTOR RISK. Companies that operate in different but closely related
  industries are sometimes described as being in the same broad economic sector.
  The values of stocks of many different companies in a market sector may be
  similarly affected by particular economic or market events. Although the
  Fund's principal investment strategies do not involve focusing on any
  particular sector, at times the investment manager's asset management strategy
  may cause the Fund to invest a large portion of its assets in a particular
  sector.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to Principal Risks to which it is
  otherwise

                                       85



  exposed, and may expose the Fund to additional risks, including counterparty
  credit risk, leverage risk, hedging risk, correlation risk, and liquidity
  risk.

 Counterparty credit risk is the risk that a counterparty to the derivative
 instrument becomes bankrupt or otherwise fails to perform its obligations due
 to financial difficulties, and the Fund may obtain no recovery of its
 investment or may only obtain a limited recovery, and any recovery may be
 delayed.

 Hedging risk is the risk that derivative instruments used to hedge against an
 opposite position may offset losses, but they may also offset gains.

 Correlation risk is related to hedging risk and is the risk that there may be
 an incomplete correlation between the hedge and the opposite position, which
 may result in increased or unanticipated losses.

 Liquidity risk is the risk that the derivative instrument may be difficult or
 impossible to sell or terminate, which may cause the Fund to be in a position
 to do something the investment manager would not otherwise choose, including
 accepting a lower price for the derivative instrument, selling other
 investments or foregoing another, more appealing investment opportunity.

 Leverage risk is the risk that losses from the derivative instrument may be
 greater than the amount invested in the derivative instrument.

In addition to the risks described above, the Buying Fund is subject to the
additional principal investment risks set forth below. While these additional
risks may also be risks of the Selling Fund, they are not stated as principal
investment risks of the Selling Fund. For more information regarding the Selling
Fund's principal investment risks, see "Principal Risks" in the Selling Fund's
prospectus.

- - SMALL AND MID-SIZED COMPANY RISK. Investments in small and medium companies
  often involve greater risks than investments in larger, more established
  companies because small and medium companies may lack the management
  experience, financial resources, product diversification, experience and
  competitive strengths of larger companies. Additionally, in many instances the
  securities of small and medium companies are traded only over-the-counter or
  on regional securities exchanges and the frequency and volume of their trading
  is substantially less and may be more volatile than is typical of larger
  companies.

- - QUANTITATIVE MODEL RISK. Securities selected using quantitative methods may
  perform differently from the market as a whole for many reasons, including the
  factors used in building the quantitative analytical framework, the weights
  placed on each factor, and changing sources of market returns, among others.
  There can be no assurance that these methodologies will enable the Fund to
  achieve its objective.

  Quantitative model risk relates to the portion of the Buying Fund's portfolio
  that is managed by Principal Global.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- - how each Fund's average annual total returns compare to indexes shown in the
  table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts. If sales charges
were included, the returns would be lower.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class R and Class I shares of Seligman International
Growth Fund. The second table shows total returns from hypothetical investments
in Class A, Class B and Class C shares of the RiverSource Partners International
Select Growth Fund. The inception date for Class R2 and Class R5 of the Buying
Fund is expected to be in the third quarter of 2009 and therefore performance
information for those classes is not shown. These returns are compared to the
indexes shown for the same periods. For purposes of the performance calculation
in the table we assumed:

- - the maximum sales charge of 5.75%* for Class A shares;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B, Class C** and Class R shares;

- - no sales charge for Class I shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

   * Effective Jan. 7, 2008, the maximum initial sales charge on investments in
     Class A shares of the Selling Fund is 5.75%. Although for all periods
     presented, the Selling Fund's Class A share returns reflect the 5.75%
     maximum initial sales charge, the actual returns for periods prior to Jan.
     7, 2008 would have been higher if a 4.75% maximum initial sales charge then
     in effect was incurred.

  ** Effective June 4, 2007, there is no initial sales charge on purchases of
     Class C shares of the Selling Fund. Although for all periods presented in
     the tables the Selling Funds' Class C share returns do not reflect an
     initial sales charge, the actual returns for periods prior to June 4, 2007
     would have been lower if a 1.00% maximum initial sales charge then in
     effect was incurred.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

Prior to March 31, 2000, Seligman employed subadvisers that were responsible for
providing certain portfolio management services with respect to the investments
of the Fund. From March 31, 2000 until Sept. 15, 2003, the assets of the Fund
were managed exclusively by Seligman. Since Sept. 15, 2003, Wellington
Management Company LLP has been employed as subadviser to provide portfolio

The MSCI EAFE Index, an unmanaged index, is a free float-adjusted market
capitalization index that is designed to measure developed market equity
performance, excluding the United States and Canada. The index reflects
reinvestment of all distributions and changes in market prices and reflects no
deduction for fees, expenses or taxes.

The MSCI EAFE Growth Index, an unmanaged index, is compiled from a composite of
securities markets in Europe, Australia and the Far East. The index represents
the growth half of the market capitalizations of each country index, determined
by price/book value, from the standard MSCI country indices. The index covers
the full range of developed, emerging and MSCI All Country indices, including
Free indices where applicable. The Country Growth indices are aggregated into
regional Growth indices to create the composite. The index reflects reinvestment
of all distributions and changes in market prices and reflects no deduction for
fees, expenses or taxes.

The Lipper International Multi-Cap Growth Funds Average measures the performance
of mutual funds that, by portfolio practice, invest in a variety of market
capitalization ranges without concentrating 75% of their equity assets in any
one market capitalization range over an extended period of time. Multi-cap funds
typically have 25% to 75% of their assets invested in companies strictly outside
of the U.S. with market capitalizations (on a three-year weighted basis) greater
than the 250th-largest company in the S&P/Citigroup World ex-U.S. Broad Market
Index ("BMI"). Multi-cap growth funds typically have an above-average price-to-
cash flow ratio, price-to-book ratio, and three-year sales-per-share growth
value compared to the S&P/Citigroup World ex-U.S. BMI. The average is an
unmanaged benchmark that assumes reinvestment of all distributions, if any, and
excludes the effect of fees, sales charges and taxes.

The Lipper International Funds Average measures the performance of mutual funds
which invest in equity securities whose primary trading markets are outside the
U.S. Lipper currently classifies the Fund as an International Multi-Cap Growth
Fund. The average is an unmanaged benchmark that assumes reinvestment of all
distributions, if any, and excludes the effect of fees, sales charges and taxes.

The Lipper International Multi-Cap Growth Funds Index includes the 10 largest
international multi-cap growth funds tracked by Lipper Inc. The index's returns
include net reinvested dividends. The Buying Fund's performance is currently
measured against this index for purposes of determining the performance
incentive adjustment. See Fund Management and Compensation in Exhibit B for more
information.

Investors cannot invest directly in an average or index.

The inception date for Class R2 and Class R5 of the Buying Fund is expected to
be in the third quarter of 2009 and therefore performance information for those
classes is not shown.

PROPOSAL 7. REORGANIZATION OF SELIGMAN U.S. GOVERNMENT SECURITIES FUND INTO
RIVERSOURCE SHORT DURATION U.S. GOVERNMENT FUND

Shareholders of both the Buying Fund and the Selling Fund may be entitled to
assert appraisal rights (also known as dissenters' rights of appraisal) under
provisions of Minnesota and Massachusetts state law, respectively. Please see
the discussion under the caption Appraisal Rights in Section C of this proxy
statement/prospectus for more information, including a comparison of appraisal
rights under Minnesota and Massachusetts state law. A copy of the appraisal
rights under the Massachusetts Business Corporation Act is also included as
Appendix D in this proxy statement/prospectus.

COMPARISON OF INVESTMENT OBJECTIVES

Each Fund seeks to provide a high level of current income consistent with
prudent risk or safety of principal and, in the case of the RiverSource Short
Duration U.S. Government Fund, consistent with investment in U.S. government and
agency securities.

The investment objectives for the Funds are as follows:

          SELLING FUND: Seligman U.S. Government Securities Fund seeks to
                        provide a high level of current income consistent with
                        prudent investment risk.

          BUYING FUND: RiverSource Short Duration U.S. Government Fund seeks to
                       provide shareholders with a high level of current income
                       and safety of principal consistent with investment in
                       U.S. government and government agency securities.

Because any investment involves risk, there is no assurance the Fund's objective
can be achieved. Only shareholders can change the Fund's objective.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests predominantly in debt securities issued or guaranteed by the
U.S. government, its agencies or instrumentalities, or government-sponsored
enterprises. In favorable market conditions, the Buying Fund may also invest in
debt securities that are not issued by the U.S. government, its agencies or
instrumentalities, or that are denominated in currencies other than the U.S.
dollar. Under normal market conditions the Buying Fund will maintain an average
portfolio duration of one to three years while the Selling Fund's strategy does
not specify an average duration target range. At Jan. 31, 2009, the average
portfolio duration was 4.19 years for the Selling Fund and 1.76 years for the
Buying Fund.

DETAILED STRATEGIES FOR THE SELLING FUND AND THE BUYING FUND ARE SET FORTH
BELOW:

SELIGMAN U.S. GOVERNMENT SECURITIES FUND (SELLING FUND)

The Fund will invest at least 80% of its net assets in U.S. government
securities which are debt securities issued or guaranteed by the U.S.
government, its agencies or instrumentalities, or government sponsored
enterprises. Although certain of the securities in which the Fund may invest are
backed by the full faith and credit of the U.S. government (and thus involve
minimal credit risk), other securities in which the Fund may invest are backed
only by the credit of a U.S. federal agency, instrumentality or government
sponsored enterprise that issued the security (and thus may have increased
credit risk). Securities backed by the full faith and credit of the U.S.
government include direct obligations of the U.S. Treasury (including bills,
notes, and bonds) and mortgage-backed securities guaranteed by the Government
National Mortgage Association (GNMA). Examples of securities not backed by the
full faith and credit of the U.S. government include securities issued by the
Student Loan Marketing Association (Sallie Mae), the Federal Home Loan Banks
(FHLBs), Federal Home Loan Mortgage Corporation (Freddie Mac) or the Federal
National Mortgage Association (Fannie Mae).

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

- - Reviewing credit characteristics and the interest rate outlook.

- - Identifying and buying securities that are high quality or have similar
  qualities, in the investment manager's opinion, even though they are not rated
  or have been given a lower rating by a rating agency.

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

- - The security is overvalued relative to alternative investments.

- - The investment manager wishes to lock-in profits.

- - Changes in the interest rate or economic outlook.

- - The investment manager identifies a more attractive opportunity.


                                       91





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.

RIVERSOURCE SHORT DURATION U.S. GOVERNMENT FUND (BUYING FUND)

Under normal market conditions, at least 80% of the Fund's net assets are
invested in debt securities issued or guaranteed as to principal and interest by
the U.S. government, or its agencies or instrumentalities. Shareholders will be
given at least 60 days' notice of any change in the 80% policy. The Fund invests
in direct obligations of the U.S. government, such as Treasury bonds, bills, and
notes, and of its agencies and instrumentalities. The Fund may invest to a
substantial degree in securities issued by various entities sponsored by the
U.S. government, such as Fannie Mae and Freddie Mac. These issuers are chartered
or sponsored by acts of Congress; however, their securities are neither issued
nor guaranteed by the United States Treasury.

When market conditions are favorable, the Fund may also invest in debt
securities that are not issued by the U.S. government, its agencies or
instrumentalities, or that are denominated in currencies other than the U.S.
dollar.

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

- - Reviewing credit characteristics and the interest rate outlook.

- - Identifying and buying securities that are high quality or have similar
  qualities, in the investment manager's opinion, even though they are not rated
  or have been given a lower rating by a rating agency.

Under normal market conditions, the Fund will seek to maintain an average
portfolio duration of one to three years. Duration measures the sensitivity of
bond prices to changes in interest rates. The longer the duration of a bond, the
longer it will take to repay the principal and interest obligations and the more
sensitive it will be to changes in interest rates. For example, a three year
duration means a bond is expected to decrease in value by 3% if interest rates
rise 1% and increase in value by 3% if interest rates fall 1%.

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

- - The security is overvalued relative to alternative investments.

- - The investment manager wishes to lock-in profits.

- - Changes in the interest rate or economic outlook.

- - The investment manager identifies a more attractive opportunity.

The investment manager may use derivatives such as futures, options, forward
contracts and swaps, including credit default swaps, in an effort to produce
incremental earnings, to hedge existing positions, to increase market exposure
and investment flexibility, or to obtain or reduce credit exposure.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganization occurs, the combined Fund will be subject to the
fundamental investment policies of the Buying Fund. RiverSource Investments does
not believe that the differences between the fundamental investment policies of
the Funds result in any material difference in the way the Funds have been
managed or in the way the combined Fund will be managed.

For purposes of this discussion, a "fundamental" investment policy is one that
may not be changed without a shareholder vote. The Funds' fundamental investment
policies are set forth below:

COMPARISON OF NONFUNDAMENTAL POLICIES AND RELATED INVESTMENT STRATEGIES

If the Reorganization occurs, the combined Fund will be subject to the
nonfundamental investment policies of the Buying Fund. RiverSource Investments
does not believe that the differences between the nonfundamental policies of the
Funds result in any material differences in the way the Funds have been managed
or in the way the combined Fund will be managed.

The following highlights the differences in the Funds' nonfundamental investment
policies (policies that may be changed without a shareholder vote):

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



COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Fund are similar because the
Funds have similar investment objectives, principal investment strategies and
investment policies. Because the Buying Fund will generally maintain a shorter
average portfolio duration than the Selling Fund, the Buying Fund will generally
be subject to less interest rate risk than the Buying Fund. The actual risks of
investing in each Fund depend on the securities held in each Fund's portfolio
and on market conditions, both of which change over time. Both Funds are subject
to the principal investment risks described below.

- - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance
  therefore will reflect in part the ability of the portfolio managers 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.

- - CREDIT RISK. Credit risk is the risk that the issuer of a security, or the
  counterparty to a contract, will default or otherwise become unable or
  unwilling to honor a financial obligation, such as payments due on a bond or a
  note. If the Fund

                                       94






  purchases unrated securities, or if the rating of a security is reduced after
  purchase, the Fund will depend on the investment manager's analysis of credit
  risk more heavily than usual.

- - INTEREST RATE RISK. Interest rate risk is the risk of losses attributable to
  changes in interest rates. Interest rate risk is generally associated with
  bond prices: when interest rates rise, bond prices fall. In general, the
  longer the maturity or duration of a bond, the greater its sensitivity to
  changes in interest rates.

- - MARKET RISK. The market value of securities may fall or fail to rise. Market
  risk may affect a single issuer, sector of the economy, industry, or the
  market as a whole. The market value of securities may fluctuate, sometimes
  rapidly and unpredictably.

- - PREPAYMENT AND EXTENSION RISK. Prepayment and extension risk is the risk that
  a bond or other security might be called or otherwise converted, prepaid, or
  redeemed before maturity. This risk is primarily associated with asset-backed
  securities, including mortgage-backed securities. If a security is converted,
  prepaid, or redeemed before maturity, particularly during a time of declining
  interest rates, the investment managers may not be able to reinvest in
  securities providing as high a level of income, resulting in a reduced yield
  to the Fund. Conversely, as interest rates rise, the likelihood of prepayment
  decreases. The investment managers may be unable to capitalize on securities
  with higher interest rates because the Fund's investments are locked in at a
  lower rate for a longer period of time.

In addition to the risks described above, the Buying Fund is subject to the
additional principal investment risk set forth below. While this additional risk
may also be a risk of the Selling Fund, it is not stated as a principal
investment risk of the Selling Fund. For more information regarding the Selling
Fund's principal investment risks, see "Principal Risks" in the Selling Fund's
prospectus.

- - DERIVATIVES RISK. Derivatives are financial instruments that have a value
  which depends upon, or is derived from, the value of something else, such as
  one or more underlying securities, pools of securities, options, futures,
  indexes or currencies. Gains or losses involving derivative instruments may be
  substantial, because a relatively small price movement in the underlying
  security(ies), instrument, currency or index may result in a substantial gain
  or loss for the Fund. Derivative instruments in which the Fund invests will
  typically increase the Fund's exposure to principal risks to which it is
  otherwise exposed, and may expose the Fund to additional risks, including
  counterparty credit risk, hedging risk, correlation risk, liquidity risk and
  leverage risk.

 Counterparty credit risk is the risk that a counterparty to the derivative
 instrument becomes bankrupt or otherwise fails to perform its obligations due
 to financial difficulties, and the Fund may obtain no recovery of its
 investment or may only obtain a limited recovery, and any recovery may be
 delayed.

 Hedging risk is the risk that derivative instruments used to hedge against an
 opposite position may offset losses, but they may also offset gains.

 Correlation risk is related to hedging risk and is the risk that there may be
 an incomplete correlation between the hedge and the opposite position, which
 may result in increased or unanticipated losses.

 Liquidity risk is the risk that the derivative instrument may be difficult or
 impossible to sell or terminate, which may cause the Fund to be in a position
 to do something the investment manager would not otherwise choose, including
 accepting a lower price for the derivative instrument, selling other
 investments or foregoing another, more appealing investment opportunity.

 Leverage risk is the risk that losses from the derivative instrument may be
 greater than the amount invested in the derivative instrument. Certain
 derivatives have the potential for unlimited losses, regardless of the size of
 the initial investment.

PERFORMANCE

The following bar charts and tables provide some illustration of the risks of
investing in the Funds by showing, respectively:

- - how each Fund's performance has varied for each full calendar year shown in
  the bar chart; and

- - how each Fund's average annual total returns compare to indexes shown in the
  table.

Both the bar chart and the table assume that all distributions have been
reinvested. The performance of different classes varies because of differences
in sales charges and other fees and expenses. How a Fund has performed in the
past (before and after taxes) does not indicate how the Fund will perform in the
future. Performance reflects any fee waivers/expense caps in effect for the
periods reported. In the absence of such fee waivers/expense caps, performance
would have been lower.

Bar Charts. Class A share information is shown in the bar charts; the sales
charge for Class A shares is not reflected in the bar charts. If sales charges
were included, the returns would be lower.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C and Class R shares of Seligman U.S. Government
Securities Fund. The second table shows total returns from hypothetical
investments in Class A, Class B and Class C shares of the RiverSource Short
Duration U.S. Government Fund. The inception date for Class R2 of the Buying
Fund is expected to be in the third quarter of 2009 and therefore performance
information for that class is not shown. These returns are compared to the
indexes shown for the same periods. For purposes of the performance calculation
in the table we assumed:

- - the maximum sales charge of 4.50% for Class A shares of the Selling Fund* and
  the maximum sales charge for Class A shares of the Buying Fund** at the
  beginning of each period;

- - sales at the end of the period and deduction of the applicable contingent
  deferred sales charge ("CDSC") for Class B, Class C*** and Class R shares; and

- - with the exception of Class A shares, no adjustments for taxes paid by an
  investor on the reinvested income and capital gains.

    * Effective Jan. 7, 2008, the maximum initial sales charge in Class A shares
      of the Selling Fund is 4.50%. Although for all periods presented the
      Selling Fund's Class A share returns reflect the 4.50% maximum initial
      sales charge, the actual returns for periods prior to Jan. 7, 2008 would
      have been lower if a 4.75% maximum initial sales charge then in effect was
      incurred.

   ** On March 3, 2008, the maximum sales charge for Class A shares of the
      Buying Fund changed from 4.75% to 3.00%. Class A share performance for the
      Buying Fund for each period of five years, ten years and since inception
      reflects the maximum sales charge of 4.75%, which was in effect at the
      beginning of each of those periods. Class A share performance for the
      Buying Fund for the one year period reflects the maximum sales charge of
      3.00%, which was in effect at the beginning of that period.

  *** Effective June 4, 2007, there is no initial sales charge on purchases of
      Class C shares of the Selling Fund. Although for all periods presented the
      Selling Fund's Class C share returns do not reflect an initial sales
      charge, the actual returns for periods prior to June 4, 2007 would have
      been lower if a 1.00% maximum initial sales charge then in effect was
      incurred.

AFTER-TAX RETURNS

After-tax returns are shown only for Class A shares. After-tax returns for the
other classes will vary. After-tax returns are calculated using the highest
historical individual federal marginal income tax rate and do not reflect the
impact of state and local taxes. Actual after-tax returns will depend on your
tax situation and most likely will differ from the returns shown in the table.
If you hold your shares in a tax-deferred account, such as a 401(k) plan or an
IRA, the after-tax returns do not apply to you since you will not incur taxes
until you begin to withdraw from your account.

The return after taxes on distributions for a period may be the same as the
return before taxes for the same period if there were no distributions or if the
distributions were small. The return after taxes on distributions and sale of
Fund shares for a period may be greater than the return before taxes for the
same period if there was a tax loss realized on sale of Fund shares. The benefit
of the tax loss (since it can be used to offset other gains) may result in a
higher return.

During the periods shown in the bar chart, the highest return for a calendar
quarter was +3.53% (quarter ended Sept. 30, 2001) and the lowest return for a
calendar quarter was -1.49% (quarter ended March 31, 2000).

The performance of other classes may vary from that shown because of differences
in expenses.

The Buying Fund formerly was a "feeder" fund in a master/feeder arrangement
where the Buying Fund invested all of its assets in a corresponding "master"
fund with an identical investment objective and investment strategies. As of
Oct. 18, 2005, the Buying Fund became a stand-alone fund that invests directly
in a portfolio of securities. The information shown in the table and in the
financial highlights for the Buying Fund includes the activity of the Buying
Fund when it was a feeder in a master/feeder arrangement.

ADDITIONAL INFORMATION ABOUT EACH REORGANIZATION

TERMS OF THE REORGANIZATIONS

The Board has approved the Agreement, the form of which is attached as Exhibit
A. The Agreement provides for Reorganizations on the following terms:

- - Each Reorganization is expected to occur before the end of the third quarter
  of 2009, pending shareholder approval, receipt of any necessary regulatory
  approvals and satisfaction of any other conditions to closing. However,
  following shareholder approval, each Reorganization may happen at any time
  agreed to by the applicable Selling Fund and the corresponding Buying Fund.

- - Each Selling Fund will transfer all of its assets to the corresponding Buying
  Fund and, in exchange, the corresponding Buying Fund will assume all the
  Selling Fund's liabilities and will issue to the Selling Fund, as applicable,
  Class A, Class B, Class C, Class R2, and Class R5 shares with an aggregate net
  asset value on the business day immediately preceding the closing of the
  Reorganization equal to the value of the assets that it receives from the
  Selling Fund, less the liabilities assumed by the corresponding Buying Fund in
  the transaction. The Reorganization Shares will immediately be distributed to
  the Selling Fund shareholders in proportion to their holdings of shares of the
  Selling Fund. As a result, shareholders of the Selling Fund will become, as
  applicable, Class A, Class B, Class C, Class R2, and/or Class R5 shareholders
  of the corresponding Buying Fund.

- - No Selling Fund and no shareholders of any Selling Fund will pay any sales
  charge in connection with its Reorganization.

- - The net asset value of each Selling Fund and the corresponding Buying Fund
  will be computed as of 3:00 p.m., Central time, or close of business, on the
  business day immediately preceding the closing date of the applicable
  Reorganization.

- - After its Reorganization, each Selling Fund will be dissolved.

CONDITIONS TO CLOSING EACH REORGANIZATION

The completion of each Reorganization is subject to certain conditions described
in the Agreement, including:

- - The Selling Fund will have declared and paid a dividend that will distribute
  all of the Selling Fund's net investment income and net capital gains, if any,
  to the shareholders of the Selling Fund for the taxable years ending on or
  prior to the closing date of the Reorganization.

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

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

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

- - The Selling Fund will have received an opinion of tax counsel to the effect
  that, although not entirely free from doubt, the shareholders of the Selling
  Fund will not recognize gain or loss for federal income tax purposes upon the
  exchange of their Selling Fund shares for the corresponding Buying Fund shares
  in connection with the Reorganization.

TERMINATION OF THE AGREEMENT

The Agreement and the transactions contemplated by it may be terminated and
abandoned with respect to any Reorganization by resolution of the Board at any
time prior to the closing date thereof. In the event of a termination,
RiverSource will bear all costs associated with the Reorganization.

TAX STATUS OF THE REORGANIZATIONS

Each Reorganization is intended to qualify for federal income tax purposes as a
tax-free reorganization under section 368(a) of the Internal Revenue Code of
1986, as amended (the "Code"). As a condition to the closing of each
Reorganization, each Selling Fund and Buying Fund will receive an opinion from
Ropes & Gray LLP to the effect that, although not free from doubt, on the basis
of existing provisions of the Code, U.S. Treasury regulations issued thereunder,
current administrative rules, pronouncements and court decisions, for federal
income tax purposes:

- - The transfer of the Selling Fund's assets to the Buying Fund in exchange for
  Class A, Class B, Class C, Class R2 and/or Class R5 shares, as applicable, of
  the Buying Fund and the assumption by the Buying Fund of the Selling Fund's
  liabilities, followed by the distribution of those Class A, Class B, Class C,
  Class R2 and/or Class R5 shares, as applicable, to the Selling Fund's
  shareholders and the termination of the Selling Fund, will be a
  "reorganization" within the meaning of Section 368(a)(1) of the Code, and the
  Selling Fund and the Buying Fund will each be a "party to the reorganization"
  within the meaning of Section 368(b) of the Code.


                                       99





- - Under Section 361 of the Code, no gain or loss will be recognized by the
  Selling Fund upon the transfer of all of its assets to the Buying Fund or on
  the distribution by the Selling Fund of Class A, Class B, Class C, Class R2
  and/or Class R5 shares, as applicable, of the Buying Fund to Selling Fund
  shareholders in liquidation.

- - Under Section 354 of the Code, the shareholders of the Selling Fund will not
  recognize gain or loss upon the exchange of their Class A, Class B, Class C,
  Class R and/or Class I shares, as applicable, of the Selling Fund solely for
  Class A, Class B, Class C, Class R2 and/or Class R5 shares, as applicable, of
  the Buying Fund as part of the Reorganization.

- - Under Section 358 of the Code, the aggregate tax basis of the Class A, Class
  B, Class C, Class R2 and/or Class R5 shares, as applicable, of the Buying Fund
  that a Selling Fund shareholder receives in the Reorganization will be the
  same as the aggregate tax basis of the Class A, Class B, Class C, Class R
  and/or Class I shares, as applicable, of the Selling Fund exchanged therefor.

- - Under Section 1223(1) of the Code, the holding period for the Class A, Class
  B, Class C, Class R2 and/or Class R5 shares, as applicable, of the Buying Fund
  that a Selling Fund shareholder receives in the Reorganization will include
  the period for which he or she held the Class A, Class B, Class C, Class R
  and/or Class I shares, as applicable, of the Selling Fund exchanged therefor,
  provided that on the date of the exchange he or she held such Selling Fund
  shares as capital assets.

- - Under Section 1032 of the Code, no gain or loss will be recognized by the
  Buying Fund upon the receipt of the Selling Fund's assets solely in exchange
  for the issuance of the Buying Fund's Class A, Class B, Class C, Class R2
  and/or Class R5 shares, as applicable, to the Selling Fund and the assumption
  of all of the Selling Fund's liabilities by the Buying Fund.

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

- - Under Section 1223(2) of the Code, the Buying Fund's holding periods in the
  assets received from the Selling Fund will include the Selling Fund's holding
  periods in such assets.

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

Ropes & Gray LLP will express no view with respect to the effect of a
Reorganization on any transferred asset as to which any unrealized gain or loss
is required to be recognized under federal income tax principles (i) at the end
of a taxable year or upon the termination thereof, or (ii) upon the transfer of
such asset regardless of whether such a transfer would otherwise be a non-
taxable transaction.

The opinion will be based on certain factual certifications made by the officers
of the Selling Fund and the Buying Fund and will also be based on customary
assumptions. The opinion will note and distinguish certain published precedent,
and it is possible that the Internal Revenue Service (the "IRS") could disagree
with Ropes & Gray LLP's opinion.

Opinions of counsel are not binding upon the IRS or the courts. If a
Reorganization is consummated but does not qualify as a tax-free reorganization
under the Code, a shareholder of the Selling Fund would recognize a taxable gain
or loss equal to the difference between his or her tax basis in his or her
Selling Fund shares and the fair market value of the shares of the Buying Fund
he or she received. Shareholders of a Selling Fund should consult their tax
advisors regarding the effect, if any, of the Reorganization in light of their
individual circumstances.

In the case of some of the Selling Funds, portfolio manager substitutions
independent of the Reorganizations have occurred and resulted in substantial
portfolio turnover. In addition, a portion or all of the portfolio assets of any
Selling Fund may be sold in connection with its Reorganization. The actual tax
impact of such sales depends on the difference between the price at which such
portfolio assets are sold and the Selling Fund's tax basis in such assets. Any
net capital gains recognized in these sales will be distributed to Selling Fund
shareholders as capital gain dividends (to the extent of net realized long-term
capital gains over net realized short-term capital losses) and/or ordinary
dividends (to the extent of net realized short-term capital gains over net
realized long-term capital losses) during or with respect to the year of sale,
and such distributions will be taxable to shareholders. Because each
Reorganization will end the tax year of the applicable Selling Fund, it will
accelerate distributions to shareholders from the Selling Fund for its short tax
year ending on the date of the Reorganization. Those tax year-end distributions
will be taxable and will include any capital gains resulting from portfolio
turnover prior to the Reorganization.

Prior to the closing of each Reorganization, the Selling Fund will, and the
Buying Fund may, declare a distribution to shareholders, which, together with
all previous distributions, will have the effect of distributing to shareholders
all of its investment company taxable income (computed without regard to the
deduction for dividends paid), net tax-exempt income, if any, and net realized
capital gains, if any, through the closing of the Reorganization. These
distributions will be taxable to shareholders.


                                       100



A Fund's ability to carry forward capital losses and to use them to offset
future gains may be limited. First, a Fund's "pre-acquisition losses" (including
capital loss carryforwards, net current-year capital losses, and unrealized
losses that exceed certain thresholds) may become unavailable to offset gains of
the combined Fund. Second, one Fund's pre-acquisition losses cannot be used to
offset unrealized gains in another Fund that are "built in" at the time of the
Reorganization and that exceed certain thresholds ("non-de minimis built-in
gains") for five tax years. Third, a Selling Fund's loss carryforwards, as
limited under the previous two rules, are permitted to offset only that portion
of the income of the Buying Fund for the taxable year of the Reorganization that
is equal to the portion of the Buying Fund's taxable year that follows the date
of the Reorganization (prorated according to number of days). Therefore, in
certain circumstances, shareholders of a Fund may pay taxes sooner, or pay more
taxes, than they would have had a Reorganization not occurred.

In addition, the combined Fund resulting from each Reorganization will have tax
attributes that reflect a blending of the tax attributes of the two Funds at the
time of the Reorganization (including as affected by the rules set forth above).
Therefore, the shareholders of the Selling Fund will in each case receive a
proportionate share of any "built-in" (unrealized) gains in the Buying Fund's
assets, as well as any taxable gains realized by the Buying Fund but not
distributed to its shareholders prior to the Reorganization, when such gains are
eventually distributed by the Buying Fund. As a result, shareholders of a
Selling Fund may receive a greater amount of taxable distributions than they
would have had the Reorganization not occurred. And any pre-acquisition losses
of the Selling Fund (whether realized or unrealized) remaining after the
operation of the limitation rules described above will become available to
offset capital gains realized after the Reorganization and thus may reduce
subsequent capital gain distributions to a broader group of shareholders than
would have been the case absent such Reorganization, such that the benefit of
those losses to Selling Fund shareholders may be further reduced relative to
what the benefit would have been had the Reorganization not occurred.

The impact of the rules described above will depend on the relative sizes of,
and the losses and gains (both realized and unrealized) in, each Fund at the
time of its Reorganization and thus cannot be calculated precisely prior to the
Reorganization.

The realized and unrealized gains and losses of each Fund at the time of its
Reorganization will determine the extent to which the combining Funds'
respective losses, both realized and unrealized, will be available to reduce
gains realized by the combined Fund following the Reorganization, and
consequently the extent to which the combined Fund may be required to distribute
gains to its shareholders earlier than would have been the case absent the
Reorganization. The following paragraphs provide a brief summary of the tax
impact of each Reorganization had it occurred on October 31, 2008. As noted
above, the tax impact of a Reorganization depends on each Fund's relative tax
situation at the time of the Reorganization, which situation will be different
than the tax situation on October 31, 2008, and cannot be calculated precisely
prior to the Reorganization. Due to the significant portfolio turnover of
certain of the Funds resulting from RiverSource Investments' purchase of
Seligman and portfolio manager substitutions made independent of the
Reorganizations, and the substantial volatility in the marketplace, the actual
tax impacts of the Reorganizations could differ substantially from those
described below.

Proposal 1; Reorganization of Seligman Core Fixed Income Fund into RiverSource
Diversified Bond Fund. As of October 31, 2008, Seligman Core Fixed Income Fund
(Selling Fund) and RiverSource Diversified Bond Fund (Buying Fund) had net
realized losses (including capital loss carryforwards) equal to approximately
5.7% and 3.9% of net assets, respectively. If the Reorganization had occurred on
October 31, 2008, the loss limitation rules would not have affected the combined
Fund's ability to use Selling Fund losses to offset gains recognized by the
combined Fund. Selling Fund's losses would thus have been available to reduce
subsequent capital gain distributions to shareholders of the combined Fund,
spreading the tax benefit of such losses over a larger group of shareholders
than if the Reorganization had not occurred.

Subsequent to October 31, 2008, Selling Fund experienced significant portfolio
turnover. The recognition of gain and loss resulting from such portfolio
turnover could increase the potential tax cost of the Reorganization to Selling
Fund shareholders relative to the costs described above.

Proposal 2; Reorganization of Seligman Emerging Markets Fund into Threadneedle
Emerging Markets Fund. As of October 31, 2008, Seligman Emerging Markets Fund
(Selling Fund) had a very small amount of net realized gain (0.06% of its net
assets) and no capital loss carryforwards but had net unrealized losses equal to
approximately 48.3% of its net assets. Threadneedle Emerging Markets Fund
(Buying Fund) had no capital loss carryforwards and net realized losses equal to
approximately 3.7% of its net assets and unrealized losses equal to
approximately 57.1% of its net assets. If the Reorganization had occurred on
that date, Selling Fund shareholders might have benefited from the use of Buying
Fund's losses to offset gains of the combined Fund. However, to the extent
Selling Fund realizes its unrealized losses, such losses will be subject to the
loss limitation rules and might cause Selling Fund shareholders to experience a
greater tax cost than if the Reorganization had not occurred.

Proposal 3; Reorganization of Seligman Global Growth Fund into Threadneedle
Global Equity Fund. As of October 31, 2008, Seligman Global Growth Fund (Selling
Fund) and Threadneedle Global Equity Fund (Buying Fund) had net realized losses
(including capital loss carryforwards) equal to approximately 237.4% and 94.2%
of net assets, respectively, and had net unrealized losses equal to
approximately 36.6% and 37.3% of net assets, respectively. If the Reorganization
had occurred on

                                       101



October 31, 2008, the limitation on the use of Selling Fund's realized losses to
offset gains of the combined Fund would not have had a significant negative
impact on Selling Fund shareholders because most of Selling Fund's realized
losses likely would have expired unused had the Reorganization not occurred.
However, to the extent Selling Fund realizes its unrealized losses, such losses
will be subject to the loss limitation rules and might cause Selling Fund
shareholders to experience a greater tax cost than if the Reorganization had not
occurred.

Proposal 4; Reorganization of Seligman High-Yield Fund into RiverSource High
Yield Bond Fund. As of October 31, 2008, Seligman High-Yield Fund (Selling Fund)
and RiverSource High Yield Bond Fund (Buying Fund) had net realized losses
(including capital loss carryforwards) equal to approximately 760.8% and 126.2%
of net assets, respectively, and had net unrealized losses equal to
approximately 52.2% and 35.9% of net assets, respectively. If the Reorganization
had occurred on October 31, 2008, the limitation on the use of Selling Fund's
realized losses to offset gains of the combined Fund would not have had a
significant negative impact on Selling Fund shareholders because nearly all of
Selling Fund's realized losses likely would have expired unused had the
Reorganization not occurred.

Subsequent to October 31, 2008, Selling Fund experienced significant portfolio
turnover, causing the recognition of additional losses subject to the loss
limitation rules, which could result in an increase of the potential tax cost
due to the Reorganization relative to the costs described above. Additionally,
to the extent Selling Fund further realizes its unrealized losses, the
application of the loss limitation rules to such losses might cause a further
increase in the potential tax cost to Selling Fund shareholders.

Proposal 5; Reorganization of Seligman Income and Growth Fund into RiverSource
Balanced Fund. As of October 31, 2008, Seligman Income and Growth Fund (Selling
Fund) and RiverSource Balanced Fund (Buying Fund) had net realized losses
(including capital loss carryforwards) equal to approximately 31.0% and 119.6%
of net assets, respectively, and had net unrealized losses equal to
approximately 59.2% and 21.7% of net assets, respectively. If the Reorganization
had occurred on October 31, 2008, the loss limitation rules would have
significantly limited the ability to use Selling Fund losses to offset gain of
the combined Fund. However, Selling Fund shareholders might have benefited from
the use of Buying Fund's losses to offset gains of the combined Fund.,

Subsequent to October 31, 2008, Selling Fund experienced significant portfolio
turnover, causing the recognition of additional losses subject to the loss
limitation rules, which could result in an increase of the potential tax cost
due to the Reorganization relative to the costs described above. Additionally,
to the extent Selling Fund further realizes its unrealized losses, the
application of the loss limitation rules to such losses might cause a further
increase in the potential tax cost to Selling Fund shareholders.

Proposal 6; Reorganization of Seligman International Growth Fund into
RiverSource Partners International Select Growth Fund. As of October 31, 2008,
Seligman International Growth Fund (Selling Fund) and RiverSource Partners
International Select Growth Fund (Buying Fund) had net realized losses
(including capital loss carryforwards) equal to 33.3% and 15.3% of net assets,
respectively, and had net unrealized losses equal to approximately 14.5% and
40.5% of net assets, respectively. If the Reorganization had occurred on October
31, 2008, the loss limitation rules would not likely have prevented the use of
Selling Fund's losses to offset gains of the combined Fund. However, to the
extent Selling Fund realizes its unrealized losses, based on the amount of
unrealized losses as of October 31, 2008, prior to the Reorganization, such
losses will be subject to the loss limitation rules and might cause Selling Fund
shareholders to experience a greater tax cost than if the Reorganization had not
occurred.

Proposal 7; Reorganization of Seligman U.S. Government Securities Fund into
RiverSource Short Duration U.S. Government Fund. As of October 31, 2008,
Seligman U.S. Government Securities Fund (Selling Fund) and RiverSource Short
Duration U.S. Government Fund (Buying Fund) had net realized losses (including
capital loss carryforwards) equal to approximately 8.8% and 8.1% of net assets,
respectively. If the Reorganization had occurred on October 31, 2008, the loss
limitation rules would not have affected the combined Fund's ability to use
Selling Fund losses to offset gains recognized by the combined Fund. Selling
Fund's losses would thus have been available to reduce subsequent capital gain
distributions to shareholders of the combined Fund, spreading the tax benefit of
such losses over a larger group of shareholders than if the Reorganization had
not occurred.

Subsequent to October 31, 2008, Selling Fund experienced significant portfolio
turnover. The recognition of gain and loss resulting from such portfolio
turnover could increase the potential tax cost of the Reorganization to Selling
Fund shareholders relative to the costs described above.

The tax principles described above are not expected to change. However, their
application and, at a minimum, the specific percentages noted above will change
prior to each Reorganization because of market developments and the substantial
volatility in the marketplace, any pre-Reorganization realignments or other
sales of portfolio securities that might occur or that already have occurred,
and shareholder activity in the Funds, among other changes.


                                       102



Shareholders of a Selling Fund should consult their tax advisors regarding the
effect, if any, of the Reorganization in light of their individual
circumstances. Because the foregoing discussion relates only to the federal
income tax consequences of the Reorganizations, shareholders of a Selling Fund
should also consult their tax advisors as to the state, local and foreign tax
consequences, if any, of the Reorganizations.

REASONS FOR THE PROPOSED REORGANIZATIONS AND BOARD DELIBERATIONS

The Board believes that each proposed Reorganization will be advantageous to
Selling Fund and Buying Fund shareholders based on its consideration of the
following matters:

- - TERMS AND CONDITIONS OF THE REORGANIZATION. The Board considered the terms and
  conditions of each Reorganization as described in the previous paragraphs.

- - TAX CONSEQUENCES. The Board considered the tax-free nature of each
  Reorganization. The Board also considered the relative tax situations of each
  Fund and the resulting tax impact of the Reorganization to Selling Fund
  shareholders, and believes that the benefits of each Reorganization should
  outweigh any resulting tax cost to shareholders.

- - CONTINUITY OF INVESTMENT. The Board took into account the fact that each
  Selling Fund and the corresponding Buying Fund have similar or identical
  investment objectives and, except as noted below and as discussed in more
  detail under each proposal, similar investment strategies. In particular, for
  each Reorganization:

 Proposal 1. Seligman Core Fixed Income Fund into RiverSource Diversified Bond
 Fund: The Board considered that the Funds have similar investment objectives of
 providing a high level of current income consistent with prudent risk or
 conservation of investment value. The Board considered that Seligman Core Fixed
 Income Fund seeks capital appreciation as a secondary objective. The Board
 noted the similarity of the Funds' investment strategies: Seligman Core Fixed
 Income Fund invests 80% of its net assets in fixed-income securities, while
 RiverSource Diversified Bond Fund invests 80% of its net assets in bonds and
 other debt securities. The Board observed that the Funds share a common
 benchmark, the Barclays Capital U.S. Aggregate Bond Index.

 Proposal 2. Seligman Emerging Markets Fund into Threadneedle Emerging Markets
 Fund: The Board considered that the Funds have a virtually identical objective
 of seeking long-term growth of capital. The Board considered that each of the
 Funds invests at least 80% of its net assets in securities of companies that
 are located in emerging markets countries. The Board also considered that
 RiverSource Investments serves as the investment manager for each Fund and is
 responsible for the oversight of each Fund's subadviser which provides day-to-
 day management of the Fund, and that Seligman Emerging Markets Fund is
 subadvised by Wellington and Threadneedle Emerging Markets Fund is subadvised
 by Threadneedle. The Board further observed that the Funds share a common
 benchmark, the Morgan Stanley Capital International ("MSCI") Emerging Markets
 Index.

 Proposal 3. Seligman Global Growth Fund into Threadneedle Global Equity Fund:
 The Board considered that the Funds have a virtually identical objective of
 seeking long-term growth of capital. The Board considered that Seligman Global
 Growth Fund may invest up to 15% of its assets in emerging market equities,
 while Threadneedle Global Equity Fund has no similar restrictions. The Board
 also considered that under normal market conditions, Seligman Global Growth
 Fund invests at least 40% of its net assets in the securities of non-U.S.
 companies, while Threadneedle Global Equity Fund has no similar restrictions.
 The Board also noted that RiverSource Investments serves as the investment
 manager for each Fund and is responsible for the oversight of each Fund's
 subadviser which provides day-to-day management of the Fund, and that Seligman
 Global Growth Fund is subadvised by Wellington and Threadneedle Global Equity
 Fund is subadvised by Threadneedle. The Board observed that the Funds use
 similar benchmarks with the Selling Fund using the MSCI World Index, which is
 designed to measure global developed market equity performance and the Buying
 Fund using the MSCI All Country World Index, which is intended to measure
 equity market performance in the global developed and emerging markets.

 Proposal 4. Seligman High-Yield Fund into RiverSource High Yield Bond Fund: The
 Board considered that the Funds have similar investment objectives of seeking a
 high level of current income, with capital appreciation as a secondary
 objective. The Board considered the similarity in the Funds' investment
 strategies of investing at least 80% of their net assets in high-yield debt
 instruments. The Board further observed that the Funds share a common
 benchmark, the JP Morgan Global High Yield Index.

 Proposal 5. Seligman Income and Growth Fund into RiverSource Balanced Fund: The
 Board considered that the Funds have a virtually identical objective of seeking
 a combination of capital appreciation and current income. The Board considered
 that each Fund invests predominantly in a combination of equity and fixed-
 income securities. Also, Seligman Income and Growth Fund may invest up to 10%
 of total assets in foreign securities (excluding ADRs); RiverSource Balanced
 Fund may invest up to 25% of the Fund's net assets in foreign investments
 (including ADRs). The Board further observed that the Funds share two
 benchmarks, the Barclays Capital U.S. Aggregate Bond Index and the Blended
 Index.


                                       103





 Proposal 6. Seligman International Growth Fund into RiverSource Partners
 International Select Growth Fund: The Board considered that the Funds have a
 virtually identical objective of seeking long-term capital growth and invest
 predominantly in equity securities of foreign issuers that are believed to be
 growth companies. The Board considered that Seligman International Growth Fund
 primarily invests in common stocks of medium- to large-sized companies outside
 of the United States, whereas RiverSource Partners International Select Growth
 Fund invests primarily in stocks of small- and medium-sized companies, based
 both outside and in the United States. The Board considered that Seligman
 International Growth Fund generally invests less than 25% of its assets in
 emerging markets, while RiverSource Partners International Select Growth Fund
 has no similar restrictions. The Board also noted that RiverSource Investments
 serves as the investment manager for each Fund and is responsible for the
 oversight of each Fund's subadviser which provides day-to-day management of the
 Fund, and that Seligman International Growth Fund is subadvised by Wellington
 and RiverSource Partners International Select Growth Fund is subadvised by
 Columbia WAM and Principal Global. The Board observed that the Funds share a
 common benchmark, the MSCI Europe, Australasia, Far East Growth Index.

 Proposal 7. Seligman U.S. Government Securities Fund into RiverSource Short
 Duration U.S. Government Fund: The Board considered that the Funds share
 similar investment objectives with Seligman U.S. Government Securities Fund
 seeking to provide a high level of current income consistent with prudent
 investment risk and RiverSource Short Duration U.S. Government Fund seeking to
 provide a high level of current income and safety of principal consistent with
 investment in U.S. government and government agency securities. The Board
 considered the similarity in the Funds' investment strategies of investing at
 least 80% of their net assets in U.S. government securities, which include debt
 securities issued or guaranteed by the U.S. government, its agencies or
 instrumentalities. The Board also noted that the RiverSource Short Duration
 U.S. Government Fund normally seeks to maintain an average portfolio duration
 of one to three years while the Seligman U.S. Government Securities Fund has no
 similar stated intention. Although the Funds use different benchmarks, the
 Board observed that the Barclays Capital U.S. Government Bond Index, which
 Seligman U.S. Government Securities Fund uses, is a blended index that
 incorporates the Barclays Capital U.S. 1-3 Year Government Index, which
 RiverSource Short Duration U.S. Government Fund uses.

- - EXPENSE RATIOS. The Board considered the relative expenses of the Funds.
  Specifically, the Board considered that, as of the end of each Fund's most
  recent fiscal year, the gross expense ratio and net expense ratio (reflecting
  any fee waiver or expense reimbursement because of voluntary or contractual
  expense caps) for each Selling Fund's Class A, Class B, Class C, Class R (to
  be known as Class R2), and Class I (to be known as Class R5) shares (before
  giving effect to any applicable performance incentive adjustment and excluding
  certain other fees and expenses) was higher than the gross expense ratio and
  net expense ratio for the corresponding Buying Fund's Class A, Class B, Class
  C, Class R2 and Class R5 shares (before giving effect to any applicable
  performance incentive adjustment and excluding certain other fees and expenses
  adjustment). The Board also evaluated the anticipated expense ratio impacts to
  other share classes of the Buying Funds not involved in the Reorganization.
  The Board determined that there would be a decrease in expense ratio for each
  share class of each Selling Fund as a result of its respective Reorganization,
  but noted that the level of this reduction would vary by share class. In
  particular, for each Reorganization (unless otherwise specified), expense
  impacts, with respect to a Fund's Class A shares are discussed below:

 Proposal 1. Seligman Core Fixed Income Fund into RiverSource Diversified Bond
 Fund: The Board considered that the expenses of Seligman Core Fixed Income Fund
 are expected to decline by approximately 1.08% on a gross expense basis and by
 0.42% on a net expense basis (based on current commitments of the investment
 manager and its affiliates to waive fees and cap expenses), as a result of the
 Reorganization.

 Proposal 2. Seligman Emerging Markets Fund into Threadneedle Emerging Markets
 Fund: The Board considered that Seligman Emerging Markets Fund is currently
 subject to a commitment by the investment manager and its affiliates to waive
 fees or cap expenses, and that the expenses of the Fund are expected to decline
 by approximately 0.57% on a gross expense basis and by 0.54% on a net expense
 basis (before giving effect to any applicable performance incentive adjustment
 and excluding certain other fees and expenses), as a result of the
 Reorganization.

 Proposal 3. Seligman Global Growth Fund into Threadneedle Global Equity Fund:
 The Board considered that the expenses of Seligman Global Growth Fund are
 expected to decline by approximately 0.70% (before giving effect to any
 applicable performance incentive adjustment and excluding certain other fees
 and expenses), as a result of the Reorganization.

 Proposal 4. Seligman High-Yield Fund into RiverSource High Yield Bond Fund: The
 Board considered that the expenses of Seligman High-Yield Fund are expected to
 decline by approximately 0.20% on a gross expense basis and by 0.28% on a net
 expense basis (based on current commitments of the investment manager and its
 affiliates to waive fees and cap expenses), as a result of the Reorganization.

 Proposal 5. Seligman Income and Growth Fund into RiverSource Balanced Fund: The
 Board considered that the expenses of Seligman Income and Growth Fund are
 expected to decline by approximately 0.41% (before giving effect to any
 applicable performance incentive adjustment and excluding certain other fees
 and expenses), as a result of the Reorganization.


                                       104





 Proposal 6. Seligman International Growth Fund into RiverSource Partners
 International Select Growth Fund: The Board considered that the expenses of
 Seligman International Growth Fund are expected to decline by approximately
 0.33% on a gross expense basis and by 0.51% on a net expense basis (based on
 current commitments of the investment manager and its affiliates to waive fees
 and cap expenses, and before giving effect to any applicable performance
 incentive adjustment and excluding certain other fees and expenses), as a
 result of the Reorganization.

 Proposal 7. Seligman U.S. Government Securities Fund into RiverSource Short
 Duration U.S. Government Fund: The Board considered that the expenses of
 Seligman U.S. Government Securities Fund are expected to decline by
 approximately 0.26% on a gross expense basis and by 0.41% on a net expense
 basis (based on current commitments of the investment manager and its
 affiliates to waive fees and cap expenses), as a result of the Reorganization.

- - ECONOMIES OF SCALE. The Board observed that by combining the Funds, in
  addition to potential immediate economies of scale of a larger fund, the
  combined Fund would be able take advantage of other economies of scale
  associated with a larger fund. For example, a larger fund may realize
  breakpoints more quickly, it may have an enhanced ability to effect portfolio
  transactions on more favorable terms and may have greater investment
  flexibility. Furthermore, the Board also considered that higher aggregate net
  assets resulting from each Reorganization and the opportunity for net cash
  inflows (or reduced outflows) may reduce the risk that, if net assets of the
  Selling Fund fail to grow, or diminish, its total expense ratio could rise
  from current levels as fixed expenses, such as audit expenses and accounting
  expenses that are charged on a per Fund basis, become a larger percentage of
  net assets.

- - COSTS. The Board considered the fact that a portion of the expenses of
  effecting each Reorganization (including professional fees and expenses
  related to printing and mailing proxy/prospectus materials and solicitation of
  shareholders) may be allocated to and borne by the Selling Fund, to the extent
  that such expenses are specifically allocable to the Selling Fund. Expenses of
  the Reorganization that are not allocated to and borne by the Selling Fund
  will be paid by RiverSource Investments. The investment manager has agreed to
  limit the expenses borne by a Selling Fund to its anticipated reductions in
  expenses over the first year following the Reorganization, less the expenses
  borne by the Selling Fund related to other integration-related activity. Any
  expenses not borne by a Selling Fund as a result of these limitations will be
  borne by the investment manager.

- - DILUTION. The Board considered the fact that the Reorganizations will not
  dilute the interests of the current shareholders because it would be effected
  on the basis of the relative net asset value per share of the Selling Fund and
  Buying Fund, respectively. Thus, for example, a Class A shareholder of a
  Selling Fund will receive Class A shares of the corresponding Buying Fund
  equal in value to his or her Class A shares in the Selling Fund at the time of
  the Reorganizations.

- - PERFORMANCE AND OTHER FACTORS. The Board considered the relative performance
  records of each of the Funds, noting, however, that past performance is no
  guarantee of future results. The Board also considered the fact that the
  Reorganizations should allow for a more concentrated selling effort by the
  Funds' underwriter, thereby potentially benefiting each of the Funds, and that
  reduced outflows or increased inflows could help the Buying Fund shareholders
  achieve further economies of scale (see "Economies of Scale" above). The Board
  further took into account the investment manager's belief that each Selling
  Fund, as a stand-alone fund, was less likely to experience any growth in
  assets from investor inflows in the near term. In particular, for each
  Reorganization:

 Proposal 1. Seligman Core Fixed Income Fund into RiverSource Diversified Bond
 Fund: The Board noted that the performance of RiverSource Diversified Bond Fund
 was generally stronger than the performance of Seligman Core Fixed Income Fund.
 The Board noted the weak asset level of Seligman Core Fixed Income Fund and its
 relatively weak prospects for asset growth, particularly compared to
 RiverSource Diversified Bond Fund. The Board accorded particular weight to the
 fact that RiverSource Diversified Bond Fund has substantially greater assets
 than Seligman Core Fixed Income Fund, noting that RiverSource Diversified Bond
 Fund was more than 150 times the size of Seligman Core Fixed Income Fund.

 Proposal 2. Seligman Emerging Markets Fund into Threadneedle Emerging Markets
 Fund: The Board observed that the performance of Threadneedle Emerging Markets
 Fund was competitive (top half of the Lipper peer group), though not as good as
 the performance of Seligman Emerging Markets Fund. The Board noted the
 Threadneedle Emerging Markets Fund's stronger 10 year track record. The Board
 also noted Seligman Emerging Markets Fund's relatively weak prospects for asset
 growth, particularly compared to Threadneedle Emerging Markets Fund. The Board
 observed that the Threadneedle Emerging Markets Fund was more than four times
 the size of the Seligman Emerging Markets Fund.

 Proposal 3. Seligman Global Growth Fund into Threadneedle Global Equity Fund:
 The Board noted that the performance of Threadneedle Global Equity Fund was
 generally stronger than the performance of Seligman Global Growth Fund (both on
 a relative basis and when compared to their respective peer groups). The Board
 noted the weak asset level of Seligman Global Growth Fund and its relatively
 weak prospects for asset growth, particularly compared to Threadneedle Global
 Equity Fund. The Board accorded particular weight to the fact that Threadneedle
 Global Equity Fund has substantially greater assets than

                                       105



 Seligman Global Growth Fund, noting that Threadneedle Global Equity Fund was
 more than 20 times the size of Seligman Global Growth Fund.

 Proposal 4. Seligman High-Yield Fund into RiverSource High Yield Bond Fund: The
 Board noted that the performance of RiverSource High Yield Bond Fund was
 generally stronger than the performance of Seligman High-Yield Fund (both on a
 relative basis and when compared to their respective peer groups). The Board
 noted the weak asset level of Seligman High-Yield Fund and its relatively weak
 prospects for asset growth, particularly compared to RiverSource High Yield
 Bond Fund. The Board accorded particular weight to the fact that RiverSource
 High Yield Bond Fund has substantially greater assets than Seligman High-Yield
 Fund, noting that RiverSource High Yield Bond Fund was more than five times the
 size of Seligman High-Yield Fund.

 Proposal 5. Seligman Income and Growth Fund into RiverSource Balanced Fund: The
 Board noted that the performance of RiverSource Balanced Fund was generally
 stronger than the performance of Seligman Income and Growth Fund (both on a
 relative basis and when compared to their respective peer groups). The Board
 noted the weak asset level of Seligman Income and Growth Fund and its
 relatively weak prospects for asset growth, particularly compared to
 RiverSource Balanced Fund. The Board accorded particular weight to the fact
 that RiverSource Balanced Fund has substantially greater assets than Seligman
 Income and Growth Fund, noting that RiverSource Balanced Fund was more than 13
 times the size of Seligman Income and Growth Fund.

 Proposal 6. Seligman International Growth Fund into RiverSource Partners
 International Select Growth Fund: The Board noted that the performance of
 RiverSource Partners International Select Growth Fund was generally stronger
 than the performance of Seligman International Growth Fund (both on a relative
 basis and when compared to their respective peer groups). The Board noted the
 weak asset level of Seligman International Growth Fund and its relatively weak
 prospects for asset growth, particularly compared to RiverSource Partners
 International Select Growth Fund. The Board accorded particular weight to the
 fact that RiverSource Partners International Select Growth Fund has
 substantially greater assets than Seligman International Growth Fund, noting
 that RiverSource Partners International Select Growth Fund was more than eight
 times the size of Seligman International Growth Fund.

 Proposal 7. Seligman U.S. Government Securities Fund into RiverSource Short
 Duration U.S. Government Fund: The Board observed the generally stronger track
 record of Seligman U.S. Government Securities Fund, but noted that both
 Seligman U.S. Government Securities Fund and RiverSource Short Duration U.S.
 Government Fund are currently run by the same management team and, thus, their
 respective performance, going forward, absent the Reorganization, would be
 substantially similar. The Board also noted the weak asset level of Seligman
 U.S. Government Securities Fund and its relatively weak prospects for asset
 growth, particularly compared to RiverSource Short Duration U.S. Government
 Fund. The Board accorded particular weight to the fact that RiverSource Short
 Duration U.S. Government Fund has substantially greater assets than Seligman
 U.S. Government Securities Fund, noting that RiverSource Short Duration U.S.
 Government Fund was more than nine times the size of Seligman U.S. Government
 Securities Fund.

- - POTENTIAL BENEFITS TO THE INVESTMENT MANAGER AND ITS AFFILIATES. The Board
  considered the potential benefits from the Reorganizations that could be
  realized by the investment manager and its affiliates, including the
  elimination of expenses incurred in duplicative efforts to administer separate
  Funds. The Board also noted, however, that shareholders of each Selling Fund
  are expected to benefit over time from the decrease in overall operating
  expense ratios resulting from the proposed Reorganizations as well as the
  other benefits discussed above.

BOARD DETERMINATIONS

After considering the factors described above and other relevant information, at
a meeting held on Jan. 8, 2009, the Board of each Selling Fund, including a
majority of the independent Board members, determined that participation in the
relevant Reorganization is in the best interests of each Fund and that the
interests of existing shareholders of the Fund will not be diluted as a result
of the Reorganization.

The Board of Directors of each Buying Fund approved the Agreement at a meeting
held on Jan. 8, 2009. Among other factors, the Board members considered the
terms of the Agreement, the provisions intended to avoid the dilution of
shareholder interests and the anticipated tax consequences of the
Reorganization. The Board found that participation in each Reorganization is in
the best interest of the Buying Fund and that the interest of the existing
shareholders of the Buying Fund will not be diluted as a result of the
Reorganization.

BOARD RECOMMENDATION AND REQUIRED VOTE

The Board recommends that shareholders of each Selling Fund approve the proposed
Agreement. The Agreement must be approved by the affirmative vote of a majority
of the outstanding voting securities of each Selling Fund. A vote of a majority
of the outstanding voting securities of a Selling Fund is defined in the 1940
Act, as the affirmative vote of the lesser of (a) 67% or more of the shares of
the Selling Fund that are present or represented by proxy at the Meeting, if the
holders of

                                       106






more than 50% of the outstanding shares of the Selling Fund are present in
person or by proxy at the Meeting; or (b) more than 50% of the outstanding
shares of the Selling Fund. If the Agreement is not approved for any Selling
Fund, the Board will consider what further action should be taken with respect
to such Selling Fund. The approval of the Reorganization of one Selling Fund is
not conditioned upon the approval of the Reorganization of any other Selling
Fund.

If shareholders approve the Reorganization of their Selling Fund, it is
anticipated to occur before the end of the third quarter of 2009.


                                       107





SECTION B -- MANAGER OF MANAGERS PROPOSALS

PROPOSAL 8. MANAGER OF MANAGERS PROPOSAL FOR SELIGMAN EMERGING MARKETS FUND

The Board has approved, and recommends that shareholders approve, a policy
authorizing RiverSource Investments, the investment adviser to Seligman Emerging
Markets Fund (a "Seligman Subadvised Fund"), with the approval of the Board to
enter into and materially amend a subadvisory agreement, without obtaining
shareholder approval (the "Manager of Managers Proposal").

PROPOSAL 9. MANAGER OF MANAGERS PROPOSAL FOR SELIGMAN GLOBAL GROWTH FUND

The Board has approved, and recommends that shareholders approve, a policy
authorizing RiverSource Investments, the investment adviser to Seligman Global
Growth Fund (a "Seligman Subadvised Fund"), with the approval of the Board to
enter into and materially amend a subadvisory agreement, without obtaining
shareholder approval (the "Manager of Managers Proposal").

PROPOSAL 10. MANAGER OF MANAGERS PROPOSAL FOR SELIGMAN INTERNATIONAL GROWTH FUND

The Board has approved, and recommends that shareholders approve, a policy
authorizing RiverSource Investments, the investment adviser to Seligman
International Growth Fund (a "Seligman Subadvised Fund"), with the approval of
the Board to enter into and materially amend a subadvisory agreement, without
obtaining shareholder approval (the "Manager of Managers Proposal").

ADDITIONAL INFORMATION ABOUT EACH MANAGER OF MANAGERS PROPOSAL

RiverSource Investments serves as the investment adviser to the Seligman
Subadvised Funds. However, RiverSource Investments does not make the day-to-day
investment decisions for the Seligman Subadvised Funds. Instead, RiverSource
Investments establishes an investment program for the Seligman Subadvised Funds,
and selects, compensates and evaluates the Seligman Subadvised Funds'
subadvisers. The subadvisers, in turn, make the day-to-day investment decisions
for the Seligman Subadvised Funds. For each of the Seligman Subadvised Funds,
RiverSource Investments, with the approval of the Board, may wish to hire, add
or change a subadviser to handle the day-to-day investment decisions.

Shareholder Approval of Subadvisory Agreements. Federal securities laws
generally require that shareholders approve agreements with a fund's subadviser,
as well as with the investment adviser. Shareholder action also is required if
the terms of existing agreements are changed materially or if there is a change
in control of the subadviser. In order to obtain shareholder approval, the
Seligman Subadvised Funds must call and conduct shareholder meetings, prepare
and distribute proxy materials and solicit votes from shareholders. The process
is costly and time-consuming. The Board believes that it is in shareholders'
best interests if the Board represents their interests in approving or rejecting
recommendations made by RiverSource Investments regarding subadvisers. This
approach will avoid the cost and delay associated with holding shareholder
meetings to obtain approval for the changes.

SEC Exemptive Order. On July 16, 2002, the SEC granted RiverSource Investments
an order exempting it from the federal securities law requirements to obtain
shareholder approval regarding unaffiliated subadvisers (the "SEC Order"). The
SEC Order permits RiverSource Investments to hire new subadvisers, to rehire
existing subadvisers that have experienced a change in control and to modify
subadvisory agreements, without the approval of shareholders, provided
shareholders adopt a policy authorizing RiverSource Investments, with the
approval of the Board, to take such action.

Under the SEC Order, the Seligman Subadvised Funds and RiverSource Investments
are subject to several conditions imposed by the SEC to ensure that the
interests of the Seligman Subadvised Funds' shareholders are adequately
protected. In addition, within 90 days of hiring a new subadviser, RiverSource
Investments will provide you with an information statement that contains
substantially the same information about the subadviser, the subadvisory
agreement and the subadvisory fee that the Seligman Subadvised Fund would be
required to send to you in a proxy statement.

Shareholder approval of this proposal will not result in an increase or decrease
in the total amount of investment advisory fees paid by the Seligman Subadvised
Funds to RiverSource Investments. RiverSource Investments, directly or through
subadvisers, will continue to provide the same level of advisory and
administrative services to the Seligman Subadvised Funds as it currently
provides.

The SEC Order applies to at least the following situations:

- - RiverSource Investments recommends that a Seligman Subadvised Fund's day-to-
  day management be diversified by adding another subadviser;


                                       108





- - RiverSource Investments recommends that a subadviser be removed for
  substandard performance and replaced with a different subadviser; or

- - There is a change of control of a subadviser.

COMPARISON OF PRESENT AND PROPOSED SELECTION PROCESS FOR SUBADVISERS

Under both the current process for approval of subadvisory agreements and under
the proposed process, any change in a subadvisory agreement requires approval by
the Board. In considering whether to appoint a subadviser for any Seligman
Subadvised Fund, the Board will analyze the factors it considers relevant,
including:

- - The nature, extent and quality of services provided by a subadviser to
  investment companies comparable to the Seligman Subadvised Fund, including:

  - a subadviser's organization,

  - a subadviser's history, reputation, qualification and background, as well as
    the qualifications of its personnel,

  - a subadviser's expertise in providing portfolio management services to other
    similar portfolios and the performance history of those portfolios,

  - a subadviser's proposed investment strategy for the Seligman Subadvised
    Fund, and

  - a subadviser's compliance program;

- - A subadviser's long- and short-term performance relative to comparable mutual
  funds, other managed accounts and unmanaged indexes;

- - A subadviser's costs of services provided with respect to mutual funds or
  other managed accounts that are comparable to the Seligman Subadvised Fund;
  and

- - Other factors that the Board considers relevant to the subadviser's
  performance as an investment adviser.

The Board believes that it is in the best interest of the Seligman Subadvised
Funds and their shareholders to allow RiverSource Investments the flexibility to
provide investment advisory services to each Fund through one or more
subadvisers that have particular expertise in the type of investments on which a
Fund focuses.

Without the ability to utilize the SEC Order, in order for RiverSource
Investments to appoint a new subadviser or modify a subadvisory agreement
materially, the Board must call and hold a shareholder meeting of that Seligman
Subadvised Fund, create and distribute proxy materials and solicit votes from
the Seligman Subadvised Fund's shareholders. This process is time consuming and
costly. Without the delay inherent in holding shareholder meetings, RiverSource
Investments would be able to act more quickly to appoint a new subadviser if and
when the Board and RiverSource Investments feel that the appointment would
benefit the Seligman Subadvised Fund. The Board believes that granting
RiverSource Investments, subject to the review and approval of the Board,
maximum flexibility to select, to supervise and to evaluate subadvisers, without
incurring the otherwise necessary delay or expense of obtaining further
shareholder approval, is in the best interest of the shareholders because it
will allow each Fund to operate more efficiently.

In addition, the Board believes that it is appropriate to vest the selection,
supervision and evaluation of the subadvisers in RiverSource Investments
(subject to review by the Board) in light of RiverSource Investments' investment
advisory expertise and its ability to select the most appropriate subadviser(s).
RiverSource Investments believes that if in the future it becomes appropriate to
change a subadviser to your Seligman Subadvised Fund, it can use this experience
and expertise in evaluating and choosing subadvisers that can add the most value
to your investment in the Seligman Subadvised Fund.

Finally, the Board provides oversight of each Seligman Subadvised Fund's
subadvisory arrangements to seek to ensure that shareholders' interests are
protected whenever RiverSource Investments seeks to select a subadviser or
modify a subadvisory agreement. The Board will continue to evaluate and to
approve all new subadvisory agreements (as well as any modification to existing
subadvisory agreements.) Members of the Board will analyze such factors that
they consider to be relevant to the determination, including the nature, quality
and scope of services provided by the subadvisers. The Board will also evaluate
the subadviser's investment performance with other accounts with similar
investment objectives and will consider the subadviser's code of ethics as well
as its compliance program. As with each Fund's Investment Management Services
Agreement, the terms of each subadvisory agreement will include those required
by applicable provisions of the 1940 Act, except for the specific provisions of
the 1940 Act from which the SEC Order provides relief.

BOARD RECOMMENDATION AND REQUIRED VOTE

The Board recommends that shareholders of each Seligman Subadvised Fund approve
their respective Manager of Managers Proposal. The Manager of Managers Proposal
must be approved by the affirmative vote of a majority of the outstanding voting
securities of each Seligman Subadvised Fund. A vote of a majority of the
outstanding voting securities of a Selling Fund is defined in the 1940 Act as
the affirmative vote of the lesser of (a) 67% or more of the shares of the
Seligman Subadvised Fund that are present or represented by proxy at the
Meeting, if the holders of more than 50% of the outstanding shares of the
Seligman Subadvised Fund are present in person or by proxy at the Meeting; or
(b) more than 50% of the outstanding shares of the Seligman Subadvised Fund. The
approval of the Manager of Managers Proposal of one Seligman Subadvised Fund is
not conditioned upon the approval of the Manager of Managers Proposal of any
other Seligman Subadvised Fund or the Reorganization of that Fund.

If shareholders approve the Manager of Managers Proposal, it will take effect
shortly after the Meeting. If the Manager of Managers Proposal is not approved
for any Seligman Subadvised Fund changes in subadvisory relationships (other
than the termination of an existing subadviser) of that Seligman Subadvised Fund
will continue to require shareholder approval.

SECTION C -- PROXY VOTING AND SHAREHOLDER MEETING INFORMATION

Reference to the "Fund" in this section is a reference to each Selling Fund,
including the Seligman Subadvised Funds.

VOTING. Shareholders of record on April 3, 2009 are entitled to vote based on
the number of shares they own in the Fund irrespective of which class they own.
Unless otherwise restricted by the 1940 Act or by applicable state law, all
share classes of a Fund will vote together as a class on its proposal(s).

A quorum is required to take action at the Meeting. Except with respect to
Seligman U.S. Government Securities Fund and Seligman High-Yield Fund, the
presence at the Meeting, in person or by proxy, of shareholders entitled to cast
one-third of all shares outstanding and entitled to be cast at the Meeting shall
constitute a quorum. With respect to each of Seligman U.S. Government Securities
Fund and Seligman High-Yield Fund, the presence at the Meeting, in person or by
proxy, of shareholders of record holding a majority of the shares outstanding
and entitled to vote shall constitute a quorum.

All votes count toward a quorum, regardless of how they are voted (For, Against
or Abstain). Broker non-votes will be counted toward a quorum, but not toward
the approval of any proposal. (Broker non-votes are shares for which the
underlying owner has not voted and the broker holding the shares does not have
the authority to vote.)

PROXY SOLICITATION. If you properly authorize your proxy by internet, telephone
or facsimile, or by executing and returning the enclosed proxy card by mail, and
your proxy is not subsequently revoked, your votes will be cast at the Meeting,
and at any postponement or adjournment thereof. If you give instructions, your
votes will be cast in accordance with your instructions. If you return your
signed proxy card without instructions, your votes will be cast in favor of the
proposal(s) of your Fund.

PROXY STATEMENT DELIVERY. "Householding" is the term used to describe the
practice of delivering one copy of a document to a household of shareholders
instead of delivering one copy of a document to each shareholder in the
household. Certain shareholders of the Fund who share a common address and who
have not opted out of the householding process may receive a single copy of the
proxy statement along with the proxy card(s). If you received more than one copy
of the proxy statement, you may elect to household in the future if permitted by
your financial intermediary/financial institution. Contact the financial
intermediary/financial institution through which you purchased the Fund to
determine whether householding is an option for your account. If you received a
single copy of the proxy statement, you may opt out of householding in the
future by contacting your financial intermediary/financial institution.

An additional copy of this proxy statement may be obtained by writing to the
following address: Computershare Fund Services, c/o Operation Department, 280
Oser Ave., Hauppauge, NY 11788 or calling Computershare Fund Services, toll free
at (866) 438-8932.

REVOKING YOUR PROXY. If you execute, date and submit a proxy card with respect
to your Selling Fund, you may revoke your proxy by providing written notice to
your Fund (Attention: Secretary) at 50606 Ameriprise Financial Center,
Minneapolis, Minnesota 55474, or change your instructions by submitting a
subsequently executed and dated proxy card, by authorizing your proxy by
internet, telephone or facsimile on a later date or by attending the Meeting and
casting your vote in person. If you authorize your proxy by internet, telephone
or facsimile, you may change your instructions by authorizing a subsequent proxy
by internet, telephone or facsimile or by completing, signing and returning a
proxy card dated as of a date that is later than your last internet, telephone
or facsimile proxy authorization or by attending the Meeting and casting your
vote in person. Merely attending the Meeting without voting will not revoke your
prior proxy.

SIMULTANEOUS MEETINGS. The meeting for each Fund will be held simultaneously
with the meeting for each other Fund, with each proposal being voted on
separately by the shareholders of the relevant Fund. If any shareholder objects
to the holding of simultaneous meetings, the shareholder may move for an
adjournment of his or her Fund's meeting to a time after the Meeting so that a
meeting of that Fund may be held separately. If a shareholder makes this motion,
the persons named as proxies will take into consideration the reasons for the
objection in deciding whether to vote in favor of the adjournment, and may vote
for or against the adjournment in their discretion.

SOLICITATION OF PROXIES. The Board is asking for your vote and for you to vote
as promptly as possible. The expenses of the solicitation will be paid by
RiverSource Investments and by certain Selling Funds (see discussion of Costs
under "Reasons for the Proposed Reorganizations and Board Deliberations").
Supplementary solicitations may be made by Internet, telephone or facsimile, or
by personal contact. Computershare Fund Services has been engaged to assist in
the solicitation of proxies, at an aggregate estimated cost of $38,375.

SHAREHOLDER PROPOSALS. No proposals were received from shareholders. The Funds
do not hold annual meetings of shareholders. Shareholders who wish to make a
proposal at a Fund's next special meeting, which may not be included in the
Fund's proxy materials, must notify the relevant Fund a reasonable amount of
time before the Fund begins to print and mail its proxy materials. The fact that
a Fund receives a shareholder proposal in a timely manner does not ensure
inclusion of the proposal in the proxy materials, as there are other
requirements in the proxy rules relating to such inclusion.


                                       111





APPRAISAL RIGHTS. Shareholders of Seligman U.S. Government Securities Fund and
Seligman High-Yield Fund may be entitled to assert appraisal rights under the
Massachusetts Business Corporation Act (the "MBCA"), applicable to such Selling
Funds due to a provision in the Declaration of Trust for such funds, in
connection with each such Selling Fund's Reorganization and obtain payment of
the "fair value" of their shares, provided that they comply with the
requirements of Massachusetts law. A copy of the relevant provisions of the MBCA
is attached as Exhibit D.

Under Minnesota law, dissenting shareholders are entitled to appraisal rights
and payment for the fair value of their shares if an amendment to a Minnesota
fund's articles of incorporation materially and adversely affects a preferential
right of the shares; whereas, Massachusetts law is more limited, in that
dissenting shareholders are not so entitled unless an amendment to a
Massachusetts fund's declaration of trust affects the rights or preferences of
the shares in connection with distributions or dissolution. Under Minnesota law,
a shareholder may dissent from, and obtain fair value payment for his shares in
the event of, the fund's board of directors adoption of a plan of conversion
(e.g., changing its status to non-profit); whereas, under Massachusetts law, a
plan of conversion must be consummated for such rights to take effect. Unlike
Minnesota law, Massachusetts law provides for dissenter's rights in the event of
an amendment to a Massachusetts fund's declaration of trust or bylaws or the
entering into by the Massachusetts fund of any agreement that adds restrictions
on the transfer or registration or any outstanding shares held by the
shareholder or amends any pre-existing restrictions on the transfer or
registration of his shares in a manner which is materially adverse to the
ability of the shareholder to transfer his assets. Unlike Massachusetts law,
other than in connection with certain mergers, Minnesota law provides that the
right to obtain payment is not available to holders of shares of any class or
series of shares that is listed on the New York Stock Exchange or the American
Stock Exchange or designated as a national market security on Nasdaq Stock
Market, unless shareholders are required to accept for their shares anything
other than shares (or cash in lieu of fractional shares) of any class or series
of a domestic or foreign corporation or any other ownership interest of any
other organization. Under Minnesota law, in order to receive fair value of
shares, a dissenting shareholder must demand payment and deposit certificated
shares (if any), or comply with any restrictions on transfer of uncertificated
shares, within 30 days of the Minnesota fund's appraisal notice (which includes
the procedure to obtain payment); whereas, under Massachusetts law, the deposit
of certificates (and any required forms) must be received by the Massachusetts
fund not fewer than 40 nor more than 60 days after the fund's appraisal notice
is sent (MA Send Date). Massachusetts law specifically provides that a
shareholder may decline to exercise his appraisal rights and withdraw from the
appraisal process provided that the Massachusetts fund receives the
shareholder's notice of withdrawal within 20 days after the MA Send Date. Under
Minnesota law, a dissenter who is dissatisfied with the fair value payment
received from the Minnesota fund must provide written notice to the fund within
30 days after the fund mails the payment; whereas, under Massachusetts law, a
shareholder must provide written notice of dissatisfaction within 30 days of
shareholder's receipt of payment from the Massachusetts fund.

Notwithstanding the provisions of Massachusetts law, the SEC has taken the
position that the use of state appraisal procedures by a mutual fund would be a
violation of Rule 22c-1, the forward pricing rule, under the 1940 Act. This rule
states that no mutual fund may redeem its shares other than at net asset value
next computed after receipt of a request for redemption. It is the SEC's
position that Rule 22c-1 supersedes appraisal provisions in state statutes.

In the interest of ensuring equal valuation for all shareholders, appraisal
rights will be determined in accordance with the SEC's interpretation. As a
result, if any shareholder of either Seligman U.S. Government Securities Fund or
Seligman High-Yield Fund elects to exercise appraisal rights under Massachusetts
law, the relevant Selling Fund intends to submit this question to a court of
competent jurisdiction. In that event, a dissenting shareholder would not
receive any payment until the end of the court proceeding.

In addition, Section 13.02(a)(3) of the MBCA provides for an exception to
appraisal rights for which we believe, in light of the rationale expressed in
the Comments of The Task Force on the Revision of the Massachusetts Business
Corporation Law accompanying the MBCA, a reasonable argument exists for applying
such exception to a transaction involving an open-end mutual fund. If any
shareholder of either Seligman U.S. Government Securities Fund or Seligman High-
Yield Fund elects to exercise appraisal rights under Massachusetts law, the
relevant Selling Fund, in connection with submitting the question of the
supremacy of Rule 22c-1 to a court of competent jurisdiction, may also argue
that appraisal rights under Massachusetts law do not apply.

OTHER BUSINESS. The Board does not know of any matters to be presented at the
Meeting other than the Reorganization proposals and the Manager of Managers
proposals. If other business should properly come before the Meeting, the
persons named as proxies will vote thereon in their discretion.

ADJOURNMENT. With respect to each Selling Fund, including the Seligman
Subadvised Funds, other than Seligman U.S. Government Securities Fund and
Seligman High-Yield Fund, in the event that not enough votes are received by the
time scheduled for the Meeting, or, even if a quorum is present, if sufficient
votes in favor of any proposal(s) are not received and tabulated prior to the
time scheduled for the Meeting, the chairman of the Meeting may adjourn the
Meeting, with no notice

                                       112



other than an announcement at the Meeting, to a date not later than the 120th
day after the original record date for the Meeting to allow further solicitation
of shareholders on the proposal(s).

For each of Seligman U.S. Government Securities Fund and Seligman High-Yield
Fund, if a quorum is not present or represented at the Meeting, the holders of a
majority of the shares of a Selling Fund present at the Meeting, in person or by
proxy, shall have power to adjourn the Meeting, without notice other than
announcement at the Meeting, until the requisite number of shares entitled to
vote at the Meeting is present.

The persons named as proxies will vote in favor of adjournment those shares they
have been instructed to vote in favor of a proposal, or for which they have
received a proxy but no voting instructions. They will vote against any
adjournment those shares they have been instructed to vote against a proposal. A
shareholder vote may be taken on one or more proposals discussed in this
combined proxy statement/prospectus prior to adjournment of the Meeting if
sufficient votes have been received with respect to that particular proposal(s),
and may adjourn with respect to those proposals for which sufficient votes have
not yet been received.

SECTION D -- CAPITALIZATION, OWNERSHIP OF FUND SHARES AND FINANCIAL HIGHLIGHTS

This section contains the following information about the Funds:

          Fund
 D-2      Actual and pro forma ownership of Fund shares
 D-3      Financial Highlights of each Buying Fund



THE FUNDS' INVESTMENT MANAGER AND DISTRIBUTORS. RiverSource Investments, LLC,
200 Ameriprise Financial Center, Minneapolis, MN 55474, a wholly-owned
subsidiary of Ameriprise Financial, Inc., is the investment manager for each
Fund. RiverSource Distributors, Inc., a wholly-owned subsidiary of Ameriprise
Financial, Inc., and RiverSource Fund Distributors, Inc., an indirect wholly-
owned subsidiary of RiverSource Investments, LLC, each at 50611 Ameriprise
Financial Center, Minneapolis, MN 55474, are the distributors for each
RiverSource Fund. RiverSource Fund Distributors, Inc. is also the distributor
for each Seligman Fund.

CAPITALIZATION OF SELLING FUNDS AND BUYING FUNDS

The following table shows the capitalization of the Funds as of April 3, 2009
and on a pro forma basis, assuming the proposed Reorganization had taken place.
The pro forma combined table includes the impact of non-recurring estimated
Reorganization costs expected to be borne by certain Selling Funds, based on the
following factors. If the Reorganization is expected to result in reduction in
the expense ratio for the Selling Fund, an amount of the proxy-related eligible
expenses will be borne by the Selling Fund. This amount will not exceed the
expected one-year benefit to the Selling Fund resulting from the reduced expense
ratio, less the cost borne by the Selling Fund related to other integration-
related activity. If the Reorganization is not expected to result in a reduction
in the expense ratio for the Selling Fund, proxy-related eligible expenses will
not be borne by the Selling Fund. Proxy-related eligible expenses not borne by
the Selling Fund will be paid for by RiverSource Investments. Proxy-related
eligible expenses include auditor fees and external legal fees ("Professional
Fees"), and printing, postage, and solicitor expenses ("Proxy Vendor Expenses").
Professional Fees have been allocated among the Selling Funds on an equal
weighted basis regardless of asset size or number of accounts. Proxy Vendor
Expenses have been allocated among the Selling Funds based on number of
accounts. The amount of proxy-related eligible expenses actually borne by the
Selling Fund is limited, as described above.

The pro forma combined shares outstanding are determined by dividing the net
assets, less any Reorganization costs, of the Selling Fund by the net asset
value per share of the Buying Fund and adding the actual shares outstanding of
the Buying Fund. For the Reorganization of Seligman High-Yield Fund into
RiverSource High Yield Bond Fund, the Reorganization costs reduced pro forma
combined net assets by $113,228 for Class A, $12,793 for Class B, $6,553 for
Class C, $484 for Class R2 and $651 for Class R5. For the Reorganization of
Seligman Income and Growth Fund into RiverSource Balanced Fund, the
Reorganization costs reduced pro forma combined net assets by $56,655 for Class
A, $2,238 for Class B, $964 for Class C, $11 for Class R2 and $31 for Class R5.
For the Reorganization of Seligman U.S. Government Securities Fund into
RiverSource Short Duration U.S. Government Fund, the Reorganization costs
reduced pro forma combined net assets by $63,336 for Class A, $13,461 for Class
B, $3,589 for Class C and $531 for Class R2.

    *The combination of RiverSource Investments' initial capital investment
     (seed accounts) and RiverSource Portfolio Builder Funds (affiliated "funds-
     of-funds"), investment in Class I shares of RiverSource Partners
     International Select Growth Fund, represents aggregate ownership of 41.54%
     of the Fund. RiverSource Investments (investment manager of RiverSource
     Partners International Select Growth Fund and the funds-of-funds) do not
     invest in the Fund for the purposes of exercising control. However, since
     these ownership interests may be significant, in excess of 25% of the Fund,
     such that these entities may be deemed to control the Fund, procedures have
     been put in place to assure that public shareholders determine the outcome
     of all actions taken at shareholder meetings. Specifically, RiverSource
     Investments (which votes proxies for the seed accounts) and the funds-of-
     funds' Boards of Directors (which votes proxies for the funds-of-funds)
     vote on each proposal in the same proportion that other shareholders vote
     on the proposal. If the Reorganization is approved, RiverSource Investments
     and the funds-of-funds will own 38.73% of RiverSource Partners
     International Select Growth Fund.

Note: Class R2 and Class R5 are being added to RiverSource Partners
International Select Growth Fund in connection with the Reorganization.

EXHIBIT A

FORM OF AGREEMENT AND PLAN OF REORGANIZATION

This Agreement and Plan of Reorganization dated as of           , 2009 (the
"Agreement") is between each selling entity identified in Schedule A hereto
(each a "Selling Corporation")(1), on behalf of each series thereof identified
in Schedule A hereto as a Selling Fund (each a "Selling Fund"), each
corresponding buying entity identified in Schedule A hereto (each a "Buying
Corporation")(2), on behalf of each series thereof identified in Schedule A
hereto as the corresponding Buying Fund (each a "Buying Fund"), and RiverSource
Investments, LLC (solely for the purposes of Sections 3c and 11 of the
Agreement).

This Agreement shall be treated for all purposes as if each reorganization
between a Selling Fund and its corresponding Buying Fund contemplated hereby had
been the subject of a separate agreement. As context requires a Buying
Corporation or Selling Corporation that is not organized as a series fund and
that may not be considered or meet the definition of "Buying Fund" and "Selling
Fund" as set forth above, may be referred to as a "Buying Fund" or a "Selling
Fund," respectively, for purposes of this Agreement.

In consideration of their mutual promises, the parties agree as follows:

1.  SHAREHOLDER APPROVAL. Each Selling Fund will call a meeting of its
    shareholders for the purpose of approving the Agreement and the transactions
    it contemplates (each a "Reorganization"). Each Buying Fund agrees to
    furnish data and information, as reasonably requested, for the proxy
    statement to be furnished to shareholders of the corresponding Selling Fund.

2.  REORGANIZATION.

    a. Plan of Reorganization. Each Reorganization will be a reorganization
       within the meaning of Section 368(a) of the Internal Revenue Code of
       1986, as amended (the "Code"). At the Closing, each Selling Corporation
       will convey all of the assets of each Selling Fund to the corresponding
       Buying Fund. Each Buying Fund will assume all liabilities of the
       corresponding Selling Fund. At the Closing, each Buying Corporation will
       deliver shares of each Buying Fund, including fractional shares, to the
       corresponding Selling Corporation on behalf of the corresponding Selling
       Fund. The number of shares will be determined by dividing the value of
       the net assets attributable to each class of shares of each Selling Fund,
       computed as described in paragraph 3(a), by the net asset value of one
       share of the corresponding class of the corresponding Buying Fund,
       computed as described in paragraph 3(b). Each Selling Fund will not pay a
       sales charge on the receipt of the corresponding Buying Fund's shares in
       exchange for the assets of such Selling Fund. In addition, the
       shareholders of each Selling Fund will not pay a sales charge on
       distribution to them of shares of the corresponding Buying Fund.

    b. Closing and Effective Time of the Reorganization. The Reorganization and
       all related acts necessary to complete the Reorganization (the "Closing")
       will occur on the first day on which the New York Stock Exchange (the
       "NYSE") is open for business following approval of shareholders of each
       Selling Fund and receipt of all necessary regulatory approvals, or such
       later date as the officers of the Selling Corporation and Buying
       Corporation may agree.

3.  VALUATION OF NET ASSETS.

    a. The net asset value of each Selling Fund will be computed as of the close
       of regular trading on the NYSE on the business day immediately preceding
       the day of Closing (the "Valuation Date") using the valuation procedures
       set forth in the corresponding Buying Fund's then current prospectus.

    b. The net asset value per share of shares of each Buying Fund will be
       determined as of the close of regular trading on the NYSE on the
       Valuation Date, using the valuation procedures in each Buying Fund's then
       current prospectus.

    c. At the Closing, each Selling Fund will provide the corresponding Buying
       Fund with a copy of the computation showing the valuation of the net
       asset value per share of such Selling Fund on the Valuation Date, and
       each Buying Fund will provide the corresponding Selling Fund with a copy
       of the computation showing the determination of the net asset value per
       share of such Buying Fund on the Valuation Date. Both computations will
       be certified by an officer of RiverSource Investments, LLC, the
       investment manager.

       in the names of each corresponding Selling Fund shareholder, representing
       the respective pro rata number of full and fractional shares of such
       class of the Buying Fund due to each such shareholder. All issued and
       outstanding shares of each Selling Fund will simultaneously be cancelled

       authorized and are validly issued, fully paid and non-assessable. Since

    to such Buying Fund, each substantially to the effect that, on the basis of
    existing provisions of the Code, Treasury regulations promulgated
    thereunder, current administrative rules, pronouncements and court
    decisions, although the matter is not free from doubt, generally for federal
    income tax purposes:

    a. The acquisition by the Buying Fund of the assets of the Selling Fund in
       exchange for the Buying Fund's assumption of all liabilities of the
       Selling Fund and delivery to the Selling Fund of the acquisition shares,
       followed by the distribution by the Selling Fund of the acquisition
       shares to the shareholders of the Selling Fund in exchange for their
       Selling Fund shares, all as provided in paragraph 2(a) and 4(a) hereof,
       will constitute a reorganization within the meaning of Section 368(a) of
       the Code, and the Selling Fund and the Buying Fund will each be "a party
       to a reorganization" within the meaning of Section 368(b) of the Code;

    b. No gain or loss will be recognized by the Selling Fund upon (i) the
       transfer of its assets to the Buying Fund in exchange for the acquisition
       shares and the assumption by the Buying Fund of all liabilities of the
       Selling Fund or (ii) the distribution of the acquisition shares by the
       Selling Fund to its shareholders in liquidation, as contemplated in
       paragraph 4(a) hereof;

       contemplated in paragraph 2(a) hereof;

    d. The tax basis in the hands of the Buying Fund of the assets of the
       Selling Fund transferred to the Buying Fund in the Reorganization will be
       the same as the tax basis of such assets in the hands of the Selling Fund
       immediately prior to the transfer;

    e. The holding periods of the assets of the Selling Fund in the hands of the
       Buying Fund will include the periods during which such assets were held
       by the Selling Fund;

    f. No gain or loss will be recognized by the Selling Fund's shareholders
       upon the exchange of their shares of the Selling Fund for the acquisition
       shares;

       shareholder receives in the Reorganization will be the same as the
       aggregate tax basis of his or her Selling Fund's shares exchanged
       therefor;

    h. The Selling Fund shareholder's holding period for the acquisition shares
       will include the period for which he or she held the Selling Fund's
       shares exchanged therefor, provided that the shareholder held such
       Selling Fund's shares as capital assets on the date of the exchange; and

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

  Ropes & Gray LLP will express no view with respect to the effect of the
  Reorganization on any transferred asset as to which any unrealized gain or
  loss is required to be recognized under federal income tax principles (i) at
  the end of a taxable year or upon the termination thereof or (ii) upon the
  transfer of such asset regardless of whether such a transfer would otherwise
  be a non-taxable transaction.

  Each opinion will be based on certain factual certifications made by officers
  of the Selling Fund and the Buying Fund, and will also be based on customary
  assumptions. The opinions are not guarantees that the tax consequences of the
  Reorganizations will be as described above. The opinions will note and
  distinguish certain published precedent. There is no assurance that the
  Internal Revenue Service or a court would agree with the opinions.

    c. Each party hereto may terminate this Agreement at any time prior to the
       Closing by notice to the other party if a material condition to its

       or before the date specified for its fulfillment or a material breach of
       this Agreement is made by the other party and is not cured.

       Closing, whether before or after approval by the shareholders of each
       Selling Fund, without any liability on the part of any party or its

       other party, and shall be terminated without liability as of the close of
       business on           ,      , or a later date agreed upon by the

       Agreement, or in any document delivered in connection with this

11. EXPENSES. All fees paid to governmental authorities for the registration or
    qualification of the acquisition shares and all transfer agency costs
    related to the acquisition shares shall be borne by the relevant Buying
    Fund. Certain non-recurring Reorganization costs and related Reorganization

    of the Registration Statement, and fees and expenses of any proxy
    solicitation firm retained in connection with the Reorganization ("Proxy
    Vendor Expenses"). Professional Fees shall be allocated among each Selling
    Fund on an equal weighted basis regardless of asset size or number of
    accounts. Proxy Vendor Expenses shall be allocated among the Selling Funds
    based on number of shareholder accounts. Notwithstanding the foregoing, the
    fees and expenses borne by any Selling Fund will not exceed the excess of
    (i) the total anticipated reduction in fees and expenses expected to be
    borne by such Selling Fund over the first twelve months following its
    Reorganization over (ii) the cost expected to be borne by such Selling Fund
    related to the discontinuance of operations of Seligman Data Corp. Any fees
    and expenses that would have been eligible to be borne by a Selling Fund but
    for the preceding sentence and all other Reorganization related costs and
    expenses will be borne by RiverSource Investments, LLC. Each Selling Fund
    will bear the full cost of any brokerage or other transaction costs
    associated with the sale or purchase of portfolio securities in connection
    with its Reorganization. Should any Reorganization fail to occur,
    RiverSource Investments, LLC will bear all costs associated with the
    Reorganization.

EXHIBIT B

                            Supplemental Information

The information in the service section in this Exhibit B includes revised
shareholder service policy information as it pertains to your Fund effective on
or about June 13, 2009. This information supersedes the "Shareholder
Information" section of, and should be maintained with, your current Fund
prospectus. Please retain this supplemental information as your record for
future reference. Please contact (888) 791-3380 to confirm the final effective
date of this supplemental information.

ADDITIONAL INFORMATION APPLICABLE TO THE BUYING FUNDS

Below is information regarding the Buying Funds. All references to a Fund or the
Funds refer to a Buying Fund or the Buying Funds, respectively.

OTHER INVESTMENT STRATEGIES AND RISKS

Other Investment Strategies. In addition to the principal investment strategies
previously described, the Fund may utilize investment strategies that are not
principal investment strategies, including investment in affiliated and
nonaffiliated pooled investment vehicles (including mutual funds and exchange
traded funds ("ETFs"), also referred to as "acquired funds") ownership of which
results in the Fund bearing its proportionate share of the acquired funds' fees
and expenses. Although ETFs are designed to replicate the price and yield of a
specified market index, there is no guarantee that an ETF will track its
specified market index, which may result in a loss. For more information on
strategies and holdings, and the risks of such strategies, including derivative
instruments that the Fund may use, see the Fund's annual and semiannual reports
and the Reorganization SAI.

Unusual Market Conditions. During unusual market conditions, the Fund may
temporarily invest more of its assets in money market securities than during
normal market conditions. Although investing in these securities would serve
primarily to attempt to avoid losses, this type of investing also could prevent
the Fund from achieving its investment objective. During these times, the
portfolio managers may make frequent securities trades that could result in
increased fees, expenses and taxes, and decreased performance. Instead of
investing in money market securities directly, the Fund may invest in shares of
an affiliated money market fund. See "Cash Reserves" under the section "General
Information" for more information.

For RiverSource Partners International Select Growth Fund:

  Change in Subadviser(s). From time to time, the investment manager may add or
  change unaffiliated subadvisers. See "Additional Management Information,
  Manager of Managers Exemption." The date the current Subadviser(s) began
  serving the Fund is set forth under "Fund Management and Compensation,
  Investment Manager." When applicable, performance of the Fund prior to the
  date the current Subadviser(s) began serving was achieved by different
  subadviser(s). Similarly, the portfolio turnover rate shown in the "Financial
  Highlights" applies to the subadviser(s) serving during the relevant time-
  period. A change in subadviser(s) may result in increased portfolio turnover,
  as noted under "Portfolio Turnover."

  Multi-Manager Risk. While RiverSource Investments, as the Fund's investment
  manager, monitors each subadviser and the overall management of the Fund, to
  the extent the Fund has multiple subadvisers, each subadviser makes investment
  decisions independently from the other subadvisers. It is possible that the
  security selection process of one subadviser will not complement that of the
  other subadvisers. As a result, the Fund's exposure to a given security,
  industry, sector or market capitalization could be smaller or larger than if
  the Fund were managed by a single subadviser, which could affect the Fund's
  performance.

Securities Transaction Commissions. Securities transactions involve the payment
by the Fund of brokerage commissions to broker-dealers, on occasion as
compensation for research or brokerage services (commonly referred to as "soft
dollars"), as the portfolio managers buy and sell securities for the Fund in
pursuit of its objective. A description of the policies governing the Fund's
securities transactions and the dollar value of brokerage commissions paid by
the Fund are set forth in the Reorganization SAI. Funds that invest primarily in
fixed income securities, including RiverSource Diversified Bond Fund,
RiverSource High Yield Bond Fund and RiverSource Short Duration U.S. Government
Fund, do not typically generate brokerage commissions that are used to pay for
research or brokerage services. The brokerage commissions set forth in the
Reorganization SAI do not include implied commissions or mark-ups (implied
commissions) paid by the Fund for principal transactions (transactions made
directly with a dealer or other counterparty), including most fixed income
securities (and certain other instruments, including derivatives). Brokerage
commissions do not reflect other elements of transaction costs, including the
extent to which the Fund's purchase and sale transactions may cause the market
to move and change the market price for an investment.

Although brokerage commissions and implied commissions are not reflected in the
expense table under "Fees and Expenses," they are reflected in the total return
of the Fund.


                                       B.1





Portfolio Turnover. Trading of securities may produce capital gains, which are
taxable to shareholders when distributed. Active trading may also increase the
amount of brokerage commissions paid or mark-ups to broker-dealers that the Fund
pays when it buys and sells securities. For RiverSource Partners International
Select Growth Fund, a change in a subadviser may result in increased portfolio
turnover, which increase may be substantial, as the new subadviser realigns the
portfolio, or if the subadviser(s) trades portfolio securities more frequently.
A realignment or more active strategy could produce higher than expected capital
gains. Capital gains and increased brokerage commissions or mark-ups paid to
broker-dealers may adversely affect a fund's performance. The Fund's historical
portfolio turnover rate, which measures how frequently the Fund buys and sells
investments from year-to-year, is shown in the "Financial Highlights."

Directed Brokerage. The Fund's Board has adopted a policy prohibiting the
investment manager, or any subadviser, from considering sales of shares of the
Fund as a factor in the selection of broker-dealers through which to execute
securities transactions.

Additional information regarding securities transactions can be found in the
Reorganization SAI.

</Table>


For Threadneedle Emerging Markets Fund, Threadneedle Global Equity Fund,
RiverSource Balanced Fund and RiverSource Partners International Select Growth
Fund, the fee includes an adjustment under the terms of a performance incentive
arrangement. The adjustment is computed by comparing the Fund's performance to
the performance of an index of comparable funds published by Lipper Inc. The
index against which the Funds' performance is currently measured for purposes of
the performance incentive adjustment is the Lipper Emerging Markets Funds Index
for Threadneedle Emerging Markets Fund, Lipper Global Funds Index for
Threadneedle Global Equity Fund, Lipper Balanced Funds Index for RiverSource
Balanced Fund and Lipper International Multi-Cap Growth Funds Index for
RiverSource Partners International Select Growth Fund. In certain circumstances,
the Fund's Board may approve a change in the index. The maximum adjustment
(increase or decrease) is 0.08% of the Fund's average net assets on an annual
basis for RiverSource Balanced Fund and 0.12% for Threadneedle Emerging Markets
Fund, Threadneedle Global Equity Fund and RiverSource Partners International
Select Growth Fund.

Under the IMS Agreement, the Fund also pays taxes, brokerage commissions, and
nonadvisory expenses. A discussion regarding the basis for the Board approving
the IMS Agreement is available in the Fund's most recent annual or semiannual
shareholder report.

For Threadneedle Emerging Markets Fund and Threadneedle Global Equity Fund,
RiverSource Investments contracts with and compensates Threadneedle
International Limited (the "Subadviser" or "Threadneedle") to manage the

THIS SERVICE 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)."

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.

(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 hares. 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 Short Duration U.S. Government Fund is closed
    to new investors and new purchases. Existing shareholders in this fund may
    continue to own Class B shares and make exchanges into and out of existing
    accounts where Class B shares of this fund 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.

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.

 *  For money market funds that offer Class B shares, the distributor has
    currently agreed not to be reimbursed by the fund for distribution (12b-1)
    fees equal to 0.10% of the stated amount for Class B shares.

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.


                                       B.9



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

CLASS A, CLASS B AND CLASS C SHARES*

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.

 *  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.

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 SHARES.

The following eligible institutional investors may purchase Class R2, Class R3,
Class R4 and Class R5 shares:

- - Qualified employee benefit plans.

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

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

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

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

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 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.


                                      B.10



IN ADDITION, FOR CLASS I, CLASS R AND CLASS W 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.

SALES CHARGES

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.


                                      B.11



INITIAL SALES CHARGE -- RIGHTS 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.


                                      B.12



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.

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

- - current or retired Board members, officers or employees of the funds or
  RiverSource Investments or its affiliates, their spouses or domestic partners,
  children, parents and their spouse's or domestic partner's parents.

- - current or retired Ameriprise Financial Services, Inc. financial advisors,
  employees of financial advisors, their spouses or domestic partners, children,
  parents and their spouse's or domestic partner's parents.

- - registered representatives and other employees of affiliated or unaffiliated
  financial intermediaries having a selling agreement with the distributor,
  including their spouses, domestic partners, children, parents and their
  spouse's or domestic partner's parents.

- - portfolio managers employed by subadvisers of the funds, including their
  spouses or domestic partners, children, parents and their spouse's or domestic
  partner's parents.

- - partners and employees of outside legal counsel to the funds or the funds'
  directors or trustees who regularly provide advice and services to the funds,
  or to their directors or trustees.

- - direct rollovers from qualified employee benefit plans, provided that the
  rollover involves a transfer to Class A shares in the same fund.

- - purchases made:

  - with dividend or capital gain distributions from a fund or from the same
    class of another fund in the RiverSource Family of Funds;

  - through or under a wrap fee product or other investment product sponsored by
    a financial intermediary that charges an account management fee that has, or
    that clear trades through a financial intermediary that has, a selling
    agreement with the distributor;

  - through state sponsored college savings plans established under Section 529
    of the Internal Revenue Code; or

  - through bank trust departments.

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

- - purchases made through "employee benefit plans" created under section 401(a),
  401(k), 457 and 403(b) which:

  - have at least $1 million in plan assets at the time of investment; and

  - have a plan level or omnibus account that is maintained with the fund or its
    transfer agent; and

  - transact directly with the fund or its transfer agent through a third party
    administrator or third party recordkeeper.

For more information regarding waivers of sales charge for Class A purchases,
please see the SAI.

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 at
riversource.com or 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.


                                      B.13



- - 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:

<Table>
<Caption>
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%
</Table>


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

                                      B.14






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 AND CLASS W -- NO SALES CHARGE.
For each of Class I, Class R2, Class R3, Class R4, Class R5 and Class W 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.


                                      B.15





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.

CLASS B SHARES OF RIVERSOURCE SHORT DURATION U.S. GOVERNMENT FUND ARE CLOSED TO
NEW INVESTORS AND NEW PURCHASES. EXISTING SHAREHOLDERS IN THIS FUND MAY CONTINUE
TO OWN CLASS B SHARES AND MAKE EXCHANGES INTO AND OUT OF EXISTING ACCOUNTS WHERE
CLASS B SHARES OF THIS FUND ARE MAINTAINED.

CHECK REDEMPTION SERVICE

Class A shares of the money market funds offer check writing privileges. If you
have $2000 in a money market fund, you may request checks which may be drawn
against your account. You can elect this service on your initial application,
or, thereafter. Call (800) 221-2450 for the appropriate forms to establish this
service. If you own Class A shares that were both in another fund at NAV because
of the size of the purchase, and then exchanged into a money market fund, check
redemptions may be subject to a CDSC.

EXCHANGES

Generally, you may exchange your fund shares for shares of the same class of any
other publicly offered fund in the RiverSource Family of Funds without a sales
charge. For complete information on the fund you are exchanging into, including
fees and expenses, read that fund's prospectus carefully. Your exchange will be
priced at the next NAV calculated after your transaction request is received in
good order. You may be subject to a sales charge if you exchange from a money
market fund into an equity or fixed income fund.

IF YOU HOLD YOUR FUND SHARES IN AN ACCOUNT WITH AMERIPRISE FINANCIAL SERVICES,
YOU MAY HAVE LIMITED EXCHANGEABILITY WITHIN THE RIVERSOURCE FAMILY OF FUNDS.

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-FUND, 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

                                      B.19



  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.


                                      B.20



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.

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.


                                      B.21



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
information on the required documentation to complete a repurchase transaction.

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-fund, 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


                                      B.22



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.

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-fund, 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

                                      B.23



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

                                      B.24



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. Additional information concerning the amount and calculation of
these payments is available in the fund's SAI.

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

                                      B.25



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 SAI contains additional detail regarding
payments made by the distributor to financial intermediaries.

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 services 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 serves as investment manager to all
funds in the RiverSource Family of Funds, including those that are structured to
provide asset-allocation services to shareholders of those funds by investing in
shares of other funds (funds of funds) in the RiverSource Family of Funds
(collectively referred to as underlying funds) and to discretionary managed
accounts (collectively referred to as affiliated products) that invest
exclusively in underlying funds. These affiliated products, individually or
collectively, may own a significant percentage of the outstanding shares of the
underlying funds, and RiverSource Investments seeks to balance potential
conflicts between the affiliated products and the underlying funds in which they
invest. The affiliated products investment in the underlying funds may also have
the effect of creating economies of scale (including lower expense ratios)
because the affiliated products may own substantial portions of the shares of
underlying funds and, comparatively, a redemption of underling fund shares by
one or more affiliated products could cause the expense ratio of an underlying
fund to increase as its fixed costs would be spread over a smaller asset base.
Because of these large positions of the affiliated products, the underlying
funds may experience relatively large purchases or redemptions. 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, underlying funds may experience increased expenses as they buy
and sell securities to manage these transactions. When RiverSource Investments
structures transactions over a reasonable period of time in order to manage the
potential impact of the buy and sell decisions for the affiliated products,
these affiliated products, including funds of funds, may pay more or less for
shares of the underlying funds than if the transactions were executed in one
transaction. In addition, RiverSource Investments has an economic conflict of
interest in determining the allocation of the affiliated products' assets among
the underlying funds as it earns different fees from the underlying funds.
RiverSource Investments monitors expense levels of the funds 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. See the
SAI for information on the percent of the fund owned by affiliated products.

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.

LEGAL PROCEEDINGS. 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 fund is 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 fund or the
ability of Ameriprise Financial or its affiliates to perform under their
contracts with the fund. Information regarding certain pending and settled legal
proceedings may be found in the fund's shareholder reports and in the SAI.
Additionally, Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission 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.

EXHIBIT C

SUMMARY OF INTEGRATION RELATED CHANGES

At its Jan. 8, 2009 meeting, the Board approved certain changes to the Seligman
Funds' share class structure, service provider arrangements and shareholder
service policies, including:

SHARE CLASS STRUCTURE. Approval of the redesignation of each Seligman Fund's
Class R shares as Class R2 shares and Class I shares as Class R5 shares, as
applicable, with a shareholder servicing and pricing structure consistent with
Class R2 and Class R5 shares offered by other funds in the RiverSource Family of
Funds, discussed below.

INVESTMENT MANAGEMENT AND ADMINISTRATION. Approval of changes to each Seligman
Fund that is a Buying Fund's (i) Administrative Services Agreement to add a fee
schedule consistent with the fee schedules for other, comparable funds in the
RiverSource Family of Funds, and (ii) Investment Management Services ("IMS")
Agreement to reduce the fee by an amount at least equal to the amount of the
increase in the fee under the Administrative Services Agreement. (IMS and
Administration Agreements for Seligman Funds that are Selling Funds were not
considered at this time.)

TRANSFER AGENCY AND SHAREHOLDER SERVICING, AND PLAN ADMINISTRATION. Approval of
a transition to RiverSource Service Corporation ("RSC") as the Seligman Funds'
transfer and shareholder servicing agent, including adoption of the fee
structure paid by other funds in the RiverSource Family of Funds. The Seligman
Funds' previous transfer and shareholder servicing agent allocated 100% of its
expenses to the Seligman Funds that benefited from the services it provided.
Under the new pricing structure, fees are either asset based (Class R2 and Class
R5) or account based (Class A, Class B and Class C). See the Reorganization SAI
for more information. For Seligman Funds' Class R shares (to be redesignated as
Class R2 shares), approval of this pricing structure included adoption of a Plan
Administration Agreement, which includes an asset based fee.

CUSTODY AND SECURITIES LENDING. Approval of a transition from State Street Bank
& Trust, Co. to JPMorgan Bank, N.A. ("JPMorgan") as custodian, and approval of
JPMorgan as securities lending agent. (The Seligman Funds did not previously
have securities lending arrangements.)

SHAREHOLDER SERVICE POLICIES. Approval of changes to certain shareholder service
policies establishing a consistent shareholder experience across the combined
RiverSource Family of Funds. Certain of these changes are described below (newly
applicable shareholder service policies are set forth in Exhibit B):

  Class A at Net Asset Value. Adopt a uniform set of investor classes eligible
for waiver of Class A share front-end sales load across RiverSource Family of
Funds.

  Class A Front-End Sales Load and Breakpoint Structure. Adopt (i) a uniform
breakpoint schedule for fixed-income and equity funds, increasing the first and
second breakpoint from fixed-income and equity funds, respectively, from 4.50%
to 4.75%, and (ii) a uniform dealer reallowance structure, paying out to
financial intermediaries a maximum of 2.15% instead of 2.25% at the fourth
breakpoint (no impact to shareholders).

  Class B Contingent Deferred Sales Charge Waivers. Adopt a uniform set of
investor class waivers of CDSC on Class B shares across RiverSource Family of
Funds.

  Class B Conversion to Class A. Adopt a uniform time horizon for automatic
conversion from Class B shares to Class A shares in the month after the eighth
year of ownership. For Class B shares sold prior to the change, previous
conversion rules apply.

  Class C Contingent Deferred Sale Charge Waivers. Adopt a uniform set of
investor class waivers of CDSC on Class C shares across RiverSource Family of
Funds.

  Class R (redesignated Class R2) Contingent Deferred Sales Charge. Eliminate
the CDSC on Class R (redesignated Class R2) shares.

  Repurchase Policy. Adopt repurchase policy of 90 days and require that, for
Class B shares sold, repurchases will be put into Class A shares at net asset
value.

MASSACHUSETTS APPRAISAL RIGHTS

Massachusetts law requires that we provide shareholders of Seligman U.S.
Government Securities Fund and Seligman High-Yield Fund with a copy of the state
law on appraisal rights. Notwithstanding the provisions of the law set out
below, the SEC has taken the position that use of state appraisal procedures by
a registered mutual fund such as either such Fund would be a violation of Rule
22c-1, the forward pricing rule, under the 1940 Act. As a result, if any
shareholder elects to exercise appraisal rights under Massachusetts law, the
relevant Fund intends to submit this question to a court of competent
jurisdiction. In that event, a dissenting shareholder would not receive any
payment until the end of the court proceeding.

In addition, Section 13.02(a)(3) of the MBCA provides for an exception to
appraisal rights for which we believe, in light of the rationale expressed in
the Comments of The Task Force on the Revision of the Massachusetts Business
Corporation Law accompanying the MBCA, a reasonable argument exists for applying
such exception to a transaction involving an open-end mutual fund. If any
shareholder of either Seligman U.S. Government Securities Fund or Seligman High-
Yield Fund elects to exercise appraisal rights under Massachusetts law, the
relevant Selling Fund, in connection with submitting the question of the
supremacy of Rule 22c-1 to a court of competent jurisdiction, may also argue
that appraisal rights under Massachusetts law do not apply.

               (i) creates, alters or abolishes the stated rights or preferences
                   of the shares with respect to distributions or to
                   dissolution, including making non-cumulative in whole or in
                   part a dividend theretofore stated as cumulative;

               (ii) creates, alters or abolishes a stated right in respect of
                    conversion or redemption, including any provision relating
                    to any sinking fund or purchase, of the shares;

               (iii) alters or abolishes a preemptive right of the holder of the
                     shares to acquire shares or other securities;

               (iv) excludes or limits the right of the holder of the shares to
                    vote on any matter, or to cumulate votes, except as such
                    right may be limited by voting rights given to new shares
                    then being authorized of an existing or new class; or


                                       D.2





               (v) reduces the number of shares owned by the shareholder to a
                   fraction of a share if the fractional share so created is to
                   be acquired for cash under section 6.04;

          (5) the articles of organization or of the bylaws or the entering into
              by the corporation of any agreement to which the shareholder is
              not a party that adds restrictions on the transfer or registration
              or any outstanding shares held by the shareholder or amends any
              pre-existing restrictions on the transfer or registration of his
              shares in a manner which is materially adverse to the ability of
              the shareholder to transfer his shares;

          (6) any corporate action taken pursuant to a shareholder vote to the
              extent the articles of organization, bylaws or a resolution of the
              board of directors provides that voting or nonvoting shareholders
              are entitled to appraisal;

          (7) consummation of a conversion of the corporation to nonprofit
              status pursuant to subdivision B of PART 9; or

          (8) consummation of a conversion of the corporation into a form of
              other entity pursuant to subdivision D of PART 9.

  (b) Except as otherwise provided in subsection (a) of section 13.03, in the
      event of corporate action specified in clauses (1), (2), (3), (7) or (8)
      of subsection (a), a shareholder may assert appraisal rights only if he
      seeks them with respect to all of his shares of whatever class or series.

  (c) Except as otherwise provided in subsection (a) of section 13.03, in the
      event of an amendment to the articles of organization specified in clause
      (4) of subsection (a) or in the event of an amendment of the articles of
      organization or the bylaws or an agreement to which the shareholder is not
      a party specified in clause (5) of subsection (a), a shareholder may
      assert appraisal rights with respect to those shares adversely affected by
      the amendment or agreement only if he seeks them as to all of such shares
      and, in the case of an amendment to the articles of organization or the
      bylaws, has not voted any of his shares of any class or series in favor of
      the proposed amendment.

  (d) The shareholder's right to obtain payment of the fair value of his shares
      shall terminate upon the occurrence of any of the following events:

          (i) the proposed action is abandoned or rescinded; or

          (ii) a court having jurisdiction permanently enjoins or sets aside the
               action; or

          (iii) the shareholder's demand for payment is withdrawn with the
                written consent of the corporation.

  (e) A shareholder entitled to appraisal rights under this chapter may not
      challenge the action creating his entitlement unless the action is
      unlawful or fraudulent with respect to the shareholder or the corporation.

SECTION 13.03. ASSERTION OF RIGHTS BY NOMINEES AND BENEFICIAL OWNERS

  (a) A record shareholder may assert appraisal rights as to fewer than all the
      shares registered in the record shareholder's name but owned by a
      beneficial shareholder only if the record shareholder objects with respect
      to all shares of the class or series owned by the beneficial shareholder
      and notifies the corporation in writing of the name and address of each
      beneficial shareholder on whose behalf appraisal rights are being
      asserted. The rights of a record shareholder who asserts appraisal rights
      for only part of the shares held of record in the record shareholder's
      name under this subsection shall be determined as if the shares as to
      which the record shareholder objects and the record shareholder's other
      shares were registered in the names of different record shareholders.

  (b) A beneficial shareholder may assert appraisal rights as to shares of any
      class or series held on behalf of the shareholder only if such
      shareholder:

          (1) submits to the corporation the record shareholder's written
              consent to the assertion of such rights no later than the date
              referred to in subclause (ii) of clause (2) of subsection (b) of
              section 13.22; and

          (2) does so with respect to all shares of the class or series that are
              beneficially owned by the beneficial shareholder.

SUBDIVISION B. -- PROCEDURE FOR EXERCISE OF APPRAISAL RIGHTS

SECTION 13.20. NOTICE OF APPRAISAL RIGHTS

  (a) If proposed corporate action described in subsection (a) of section 13.02
      is to be submitted to a vote at a shareholders' meeting or through the
      solicitation of written consents, the meeting notice or solicitation of
      consents shall state that the corporation has concluded that shareholders
      are, are not or may be entitled to assert appraisal rights under this
      chapter and refer to the necessity of the shareholder delivering, before
      the vote is taken, written notice of his intent to demand payment and to
      the requirement that he not vote his shares in favor of the proposed
      action. If the corporation concludes that appraisal rights are or may be
      available, a copy of this chapter shall accompany the meeting notice sent
      to those record shareholders entitled to exercise appraisal rights.

      effective and include the materials described in section 13.22.

SECTION 13.21. NOTICE OF INTENT TO DEMAND PAYMENT

  (a) If proposed corporate action requiring appraisal rights under section

          (1) shall deliver to the corporation before the vote is taken written
              notice of the shareholder's intent to demand payment if the
              proposed action is effectuated; and

          (2) shall not vote, or cause or permit to be voted, any shares of such
              class or series in favor of the proposed action.

      written appraisal notice and form required by clause (1) of subsection (b)
      to all shareholders who satisfied the requirements of section 13.21 or, if

              shareholders of the principal terms of the proposed corporate
              action and requires the shareholder asserting appraisal rights to
              certify (A) whether or not beneficial ownership of those shares
              for which appraisal rights are asserted was acquired before that
              date and (B) that the shareholder did not vote for the
              transaction;

          (2) state:

               (i) where the form shall be sent and where certificates for
                   certificated shares shall be deposited and the date by which
                   those certificates shall be deposited, which date may not be
                   earlier than the date for receiving the required form under
                   subclause (ii);

               (ii) a date by which the corporation shall receive the form which
                    date may not be fewer than 40 nor more than 60 days after
                    the date the subsection (a) appraisal notice and form are
                    sent, and state that the shareholder shall have waived the
                    right to demand appraisal with respect to the shares unless
                    the form is received by the corporation by such specified
                    date;

               (iii) the corporation's estimate of the fair value of the shares;

               (iv) that, if requested in writing, the corporation will provide,
                    to the shareholder so requesting, within 10 days after the
                    date specified in clause (ii) the number of shareholders who
                    return the forms by the specified date and the total number
                    of shares owned by them; and

               (v) the date by which the notice to withdraw under section 13.23
                   shall be received, which date shall be within 20 days after
                   the date specified in subclause (ii) of this subsection; and

          (3) be accompanied by a copy of this chapter.

SECTION 13.23. PERFECTION OF RIGHTS; RIGHT TO WITHDRAW

  (a) A shareholder who receives notice pursuant to section 13.22 and who wishes
      to exercise appraisal rights shall certify on the form sent by the
      corporation whether the beneficial owner of the shares acquired beneficial
      ownership of the shares before the date required to be set forth in the
      notice pursuant to clause (1) of subsection (b) of section 13.22. If a
      shareholder fails to make this certification, the corporation may elect to
      treat the shareholder's shares as after-acquired shares under section
      13.25. In addition, a shareholder who wishes to exercise appraisal rights
      shall execute and return the form and, in the case of certificated shares,
      deposit the shareholder's certificates in accordance with the terms of the
      notice by the date referred to in the notice pursuant to subclause (ii) of
      clause (2) of subsection (b) of section 13.22. Once a shareholder deposits
      that shareholder's certificates or, in the case of uncertificated shares,
      returns the executed forms, that shareholder loses all rights as a
      shareholder, unless the shareholder withdraws pursuant to said subsection
      (b).

  (b) A shareholder who has complied with subsection (a) may nevertheless
      decline to exercise appraisal rights and withdraw from the appraisal
      process by so notifying the corporation in writing by the date set forth
      in the appraisal

                                       D.4






      notice pursuant to subclause (v) of clause (2) of subsection (b) of
      section 13.22. A shareholder who fails to so withdraw from the appraisal
      process may not thereafter withdraw without the corporation's written
      consent.

  (c) A shareholder who does not execute and return the form and, in the case of
      certificated shares, deposit that shareholder's share certificates where
      required, each by the date set forth in the notice described in subsection
      (b) of section 13.22, shall not be entitled to payment under this chapter.

SECTION 13.24. PAYMENT

  (a) Except as provided in section 13.25, within 30 days after the form
      required by subclause (ii) of clause (2) of subsection (b) of section
      13.22 is due, the corporation shall pay in cash to those shareholders who
      complied with subsection (a) of section 13.23 the amount the corporation
      estimates to be the fair value of their shares, plus interest.

  (b) The payment to each shareholder pursuant to subsection (a) shall be
      accompanied by:

          (1) financial statements of the corporation that issued the shares to
              be appraised,0 consisting of a balance sheet as of the end of a
              fiscal year ending not more than 16 months before the date of
              payment, an income statement for that year, a statement of changes
              in shareholders' equity for that year, and the latest available
              interim financial statements, if any;

          (2) a statement of the corporation's estimate of the fair value of the
              shares, which estimate shall equal or exceed the corporation's
              estimate given pursuant to subclause (iii) of clause (2) of
              subsection (b) of section 13.22; and

          (3) a statement that shareholders described in subsection (a) have the
              right to demand further payment under section 13.26 and that if
              any such shareholder does not do so within the time period
              specified therein, such shareholder shall be deemed to have
              accepted the payment in full satisfaction of the corporation's
              obligations under this chapter.

SECTION 13.25. AFTER-ACQUIRED SHARES

  (a) A corporation may elect to withhold payment required by section 13.24 from
      any shareholder who did not certify that beneficial ownership of all of
      the shareholder's shares for which appraisal rights are asserted was
      acquired before the date set forth in the appraisal notice sent pursuant
      to clause (1) of subsection (b) of section 13.22.

  (b) If the corporation elected to withhold payment under subsection (a), it
      must, within 30 days after the form required by subclause (ii) of clause
      (2) of subsection (b) of section 13.22 is due, notify all shareholders who
      are described in subsection (a):

          (1) of the information required by clause (1) of subsection (b) of
              section 13.24;

          (2) of the corporation's estimate of fair value pursuant to clause (2)
              of subsection (b) of said section 13.24;

          (3) that they may accept the corporation's estimate of fair value,
              plus interest, in full satisfaction of their demands or demand
              appraisal under section 13.26;

          (4) that those shareholders who wish to accept the offer shall so
              notify the corporation of their acceptance of the corporation's
              offer within 30 days after receiving the offer; and

          (5) that those shareholders who do not satisfy the requirements for
              demanding appraisal under section 13.26 shall be deemed to have
              accepted the corporation's offer.

  (c) Within 10 days after receiving the shareholder's acceptance pursuant to
      subsection(b), the corporation shall pay in cash the amount it offered
      under clause (2) of subsection (b) to each shareholder who agreed to
      accept the corporation's offer in full satisfaction of the shareholder's
      demand.

  (d) Within 40 days after sending the notice described in subsection (b), the
      corporation must pay in cash the amount if offered to pay under clause (2)
      of subsection (b) to each shareholder deserved in clause (5) of subsection
      (b).

SECTION 13.26. PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR OFFER

  (a) A shareholder paid pursuant to section 13.24 who is dissatisfied with the
      amount of the payment shall notify the corporation in writing of that
      shareholder's estimate of the fair value of the shares and demand payment
      of that estimate plus interest, less any payment under section 13.24. A
      shareholder offered payment under section 13.25 who is dissatisfied with
      that offer shall reject the offer and demand payment of the shareholder's
      stated estimate of the fair value of the shares plus interest.

  (b) A shareholder who fails to notify the corporation in writing of that
      shareholder's demand to be paid the shareholder's stated estimate of the
      fair value plus interest under subsection (a) within 30 days after
      receiving the corporation's payment or offer of payment under section
      13.24 or section 13.25, respectively, waives the right to demand payment
      under this section and shall be entitled only to the payment made or
      offered pursuant to those respective sections.

SUBDIVISION C. -- JUDICIAL APPRAISAL OF SHARES

SECTION 13.30. COURT ACTION

  (a) If a shareholder makes demand for payment under section 13.26 which
      remains unsettled, the corporation shall commence an equitable proceeding
      within 60 days after receiving the payment demand and petition the court
      to determine the fair value of the shares and accrued interest. If the
      corporation does not commence the proceeding within the 60-day period, it
      shall pay in cash to each shareholder the amount the shareholder demanded
      pursuant to section 13.26 plus interest.

  (b) The corporation shall commence the proceeding in the appropriate court of
      the county where the corporation's principal office, or, if none, its
      registered office, in the commonwealth is located. If the corporation is a
      foreign corporation without a registered office in the commonwealth, it
      shall commence the proceeding in the county in the commonwealth where the
      principal office or registered office of the domestic corporation merged
      with the foreign corporation was located at the time of the transaction.

  (c) The corporation shall make all shareholders, whether or not residents of
      the commonwealth, whose demands remain unsettled parties to the proceeding
      as an action against their shares, and all parties shall be served with a
      copy of the petition. Nonresidents may be served by registered or
      certified mail or by publication as provided by law or otherwise as
      ordered by the court.

  (d) The jurisdiction of the court in which the proceeding is commenced under
      subsection (b) is plenary and exclusive. The court may appoint 1 or more
      persons as appraisers to receive evidence and recommend a decision on the
      question of fair value. The appraisers shall have the powers described in
      the order appointing them, or in any amendment to it. The shareholders
      demanding appraisal rights are entitled to the same discovery rights as
      parties in other civil proceedings.

  (e) Each shareholder made a party to the proceeding is entitled to judgment
      (i) for the amount, if any, by which the court finds the fair value of the
      shareholder's shares, plus interest, exceeds the amount paid by the
      corporation to the shareholder for such shares or (ii) for the fair value,
      plus interest, of the shareholder's shares for which the corporation
      elected to withhold payment under section 13.25.

SECTION 13.31. COURT COSTS AND COUNSEL FEES

  (a) The court in an appraisal proceeding commenced under section 13.30 shall
      determine all costs of the proceeding, including the reasonable
      compensation and expenses of appraisers appointed by the court. The court
      shall assess the costs against the corporation, except that the court may
      assess cost against all or some of the shareholders demanding appraisal,
      in amounts the court finds equitable, to the extent the court finds such
      shareholders acted arbitrarily, vexatiously, or not in good faith with
      respect to the rights provided by this chapter.

  (b) The court in an appraisal proceeding may also assess the fees and expenses
      of counsel and experts for the respective parties, in amounts the court
      finds equitable:

          (1) against the corporation and in favor of any or all shareholders
              demanding appraisal if the court finds the corporation did not
              substantially comply with the requirements of sections 13.20,
              13.22, 13.24 or 13.25; or

          (2) against either the corporation or a shareholder demanding
              appraisal, in favor of any other party, if the court finds that
              the party against whom the fees and expenses are assessed acted
              arbitrarily, vexatiously, or not in good faith with respect to the
              rights provided by this chapter.

  (c) If the court in an appraisal proceeding finds that the services of counsel
      for any shareholder were of substantial benefit to other shareholders
      similarly situated, and that the fees for those services should not be
      assessed against the corporation, the court may award to such counsel
      reasonable fees to be paid out of the amounts awarded the shareholders who
      were benefited.

  (d) To the extent the corporation fails to make a required payment pursuant to
      sections 13.24, 13.25, or 13.26, the shareholder may sue directly for the
      amount owed and, to the extent successful, shall be entitled to recover
      from the corporation all costs and expenses of the suit, including counsel
      fees.

SHAREHOLDER LIABILITY
- -------------------------------------------------------
SELIGMAN        The shareholders of a Massachusetts
MASSACHUSET-    business trust could, under certain
TS BUSINESS     circumstances, be held personally
TRUSTS          liable as partners for its obligations.
                However, the declaration of trust
                contains express disclaimers of
                shareholder liability for acts,
                obligations or affairs of the trust.
                The declaration of trust also provides
                for indemnification and reimbursement
                of expenses out of a series' assets for
                any shareholder held personally liable
                for obligations of such series.
                Therefore, the possibility that a
                shareholder could be held liable would
                be limited to a situation in which the
                assets of the applicable series had
                been exhausted.
- -------------------------------------------------------
SELIGMAN        Under the Maryland General Corporation
MARYLAND        Law ("MGCL"), a stockholder of a
CORPORATIONS    corporation is not obligated to the
                corporation or its creditors with
                respect to the stock, except to the
                extent that the subscription price or
                other agreed upon price for the stock
                has not been paid or liability is
                otherwise imposed under the MGCL.
- -------------------------------------------------------
RIVERSOURCE     Under Minnesota law, a shareholder's
MINNESOTA       liability to the corporation or its
CORPORATIONS    creditors is limited to paying the
                amount agreed to be paid for the shares
                which the shareholder holds or has
                agreed to purchase.
- -------------------------------------------------------
SHAREHOLDER VOTING RIGHTS
- -------------------------------------------------------
SELIGMAN        At all meetings, shareholders of record
MASSACHUSET-    entitled to vote have one vote for each
TS BUSINESS     share (and each fractional share shall
TRUSTS          be entitled to a proportionate
                fractional vote) standing in his name
                on the books of the trust on the record
                date, either in person or by proxy.

                The shareholders have the power to vote
                (i) for the election of trustees, (ii)
                with respect to any investment advisory
                contract, (iii) with respect to
                termination of the trust, (iv) with
                respect to any amendment of the
                declaration of trust, (v) with respect
                to any merger, consolidation or sale of
                assets, (vi) with respect to
                incorporation of the trust, (vii) to
                the same extent as stockholders of a
                Massachusetts business corporation as
                to whether or not a court action,
                proceeding or claim should or should
                not be brought or maintained
                derivatively or as a class action on
                behalf of the trust or shareholder, and
                (viii) with respect to such additional
                matters relating to the trust as
                required by law, the declaration of
                trust, the bylaws or any registration
                of the trust with the SEC (or any
                successor agency) or any state, or as
                and when the trustees may consider
                necessary or desirable.

                There is no cumulative voting in the
                election of trustees.

                On any matter submitted to a vote of
                shareholders of the trust, all shares
                entitled to vote will be voted by
                individual shares, except that (1) when
                required by the 1940 Act, shares will
                be voted in the aggregate and not by
                individual series, and (2) when the
                trustees have determined that the
                matter affects only the interests of
                shareholders of a limited number of
                series, then only the shareholders of
                such series will be entitled to vote on
                the matter. Classes within a series
                shall vote with all other shares of the
                series except that the trustees may
                provide that any class shall vote
                separately as a class as to any matter
                when (i) required by law, rule or
                exemptive order, (ii) they determine
                that such matter affects only the
                interests of shares of such class or
                affects the interests of shares of such
                class in a manner different from that
                of the other classes or (iii) they
                otherwise determine that to do so is
                desirable and in the best interests of
                the shareholders of such class under
                the circumstances.

- -------------------------------------------------------
SELIGMAN        On each matter submitted to vote of the
MARYLAND        stockholders, each holder of a share of
CORPORATIONS    any series or class issued by the
                corporation ("Common Stock") is
                entitled to one vote for each share
                standing held irrespective of the
                series of Common Stock ("Series") and
                all shares of all Series will vote as a
                single class ("Single Class Voting");
                except, that (a) as to any matter
                requiring a separate vote of any Series
                by the 1940 Act or would be required
                under the MGCL, the requirements as to
                a separate vote by that Series apply in
                lieu of Single Class Voting as
                described above; (b) in the event that
                the separate vote requirements referred
                to in (a) above apply with respect to
                one or more Series, then, subject to
                (c) below, the shares of all other
                Series will vote as a single class; and
                (c) as to any matter which does not
                affect the interest of a particular
                Series, only the holders of shares of
                the one or more affected Series will be
                entitled to vote.

                Holders of shares of Common Stock of
                the corporation are not be entitled to
                cumulative voting in the election of
                directors or on any other matter.

                As to any matter with respect to which
                a separate vote of any class is
                required by the 1940 Act or by MGCL
                (including, without limitation,
                approval of any plan, agreement or
                other arrangement relating to
                expenses), such requirement as to a
                separate vote by the class applies in
                lieu of single class voting, and, if
                permitted by the 1940 Act or any rules,
                regulations or orders thereunder and
                MGCL, all classes of a particular
                Series vote together as a single class
                on any matter that has the same effect
                on each class of that Series. As to any
                matter that does not affect the
                interest of a particular class, only
                the holders of shares of the affected
                class are entitled to vote.
- -------------------------------------------------------
RIVERSOURCE     At all meetings of the shareholders,
MINNESOTA       each shareholder of record entitled to
CORPORATIONS    vote is entitled to one vote for each
                dollar of net asset value (number of
                shares owned times net asset value per
                share) and each fractional dollar
                amount is entitled to a proportionate
                fractional vote.

                Shareholders have the power to vote (i)

                proposed sale of all or substantially
                all of the corporation's property and
                assets not in the usual and regular
                course of its business; and (v) on the
                proposed dissolution of the
                corporation.

                At all elections of directors, each
                shareholder is entitled to as many
                votes equal to the number of dollars of
                net asset value of shares owned
                multiplied by the number of directors
                to be elected and may cast all of such

                rules and regulations promulgated
                thereunder; (ii) when the Board of
                Directors ("board of directors")
                determines that a matter affects series
                in a materially different way; or (iii)

                a matter affects only one or some of
                the series. In addition, under
                Minnesota law, shareholders are

SHAREHOLDER MEETINGS
- -------------------------------------------------------
SELIGMAN        The declaration of trust and bylaws do
MASSACHUSET-    not address annual shareholder

TRUSTS          are not required for business trusts
                under the General Laws of
                Massachusetts.

                Special or extraordinary meetings of

                the stockholders.

                In addition, a special meeting of
                stockholders shall be called by the
                secretary of the corporation on the
                written request of stockholders holding
                at least a majority of the voting power
                of all shares entitled to vote. The
                stockholders must send written notice
                to the secretary and other procedural
                requirements must be met.

                The secretary of the Corporation will
                also call a special meeting of the
                stockholders on the written request of
                stockholders entitled to cast not less
                than a majority of all the votes
                entitled to be cast at such meeting.
                Any stockholder of record seeking to
                have stockholders request a special
                meeting must send written notice to the
                secretary (the "Record Date Request
                Notice") requesting the Board of
                Directors to fix a record date to
                determine the stockholders entitled to
                request a special meeting (the "Request
                Record Date"). The Record Date Request
                Notice must state the purpose of the
                meeting and the matters proposed to be
                acted on it, signed by one or more
                stockholders of record as of the date
                of signature, bear the date of
                signature of each such stockholder (or
                their agent) and state all information
                that must be disclosed in solicitations
                of proxies for election of directors in
                an election contest (even if an
                election contest is not involved), or
                is otherwise required, pursuant to
                Regulation 14A (or any successor
                provision) under the Securities
                Exchange Act of 1934, as amended (the
                "Exchange Act"). Upon receiving the
                Record Date Request Notice, the Board
                of Directors may fix a Request Record
                Date that may not precede and also not
                be more than ten days after the close
                of business on the date on which the
                resolution fixing the Request Record
                Date is adopted by the Board of
                Directors. If the Board of Directors,
                within ten days after the date on which
                a valid Record Date Request Notice is
                received, fails to adopt a resolution
                fixing the Request Record Date, the
                Request Record Date shall be the close
                of business on the tenth day after the
                first date on which the Record Date
                Request Notice is received by the
                secretary.

                In order for any stockholder to request
                a special meeting, one or more written
                requests for a special meeting signed
                by stockholders of record (or their
                agents) as of the Request Record Date
                entitled to cast not less than a
                majority (the "Special Meeting
                Percentage") of all of the votes
                entitled to be cast at such meeting
                (the "Special Meeting Request") must be
                delivered to the secretary.
                Additionally, the Special Meeting
                Request (a) shall set forth the purpose
                of the meeting and the matters proposed
                to be acted on at it (which is limited
                to the lawful matters set forth in the
                Record Date Request Notice received by
                the secretary), (b) shall bear the date
                of signature of each such stockholder
                (or such agent) signing the Special
                Meeting Request, (c) shall set forth
                the name and address, as they appear in
                the Corporation's books, of each
                stockholder signing such request (or on
                whose behalf the Special Meeting
                Request is signed) and the class,
                series and number of all shares of
                stock of the Corporation which are
                owned by each such stockholder, and the
                nominee holder for, and number of,
                shares owned by such stockholder
                beneficially but not of record, (d)
                shall be sent to the secretary by
                registered mail, return receipt
                requested, and (e) shall be received by
                the secretary within 60 days after the
                Request Record Date. Any stockholder
                requesting a special stock holder
                meeting may revoke his, her or its
                request for a special meeting at any
                time by written revocation delivered to
                the secretary.

                The secretary will inform the

                reasonably estimated cost of preparing
                and mailing the notice of meeting
                (including the corporation's proxy
                materials). The secretary shall not be
                required to call a special meeting upon
                stockholder request and such meeting
                shall not be held unless, in addition
                to the aforementioned documents, the
                secretary receives payment of such
                reasonably estimated cost prior to the
                mailing of any notice of the meeting.

                Any special meeting to be held pursuant
                to stockholders' request may not be
                held more than 90 days after the record
                date for the meeting.

                and place for a meeting.

                If a regular meeting of shareholders
                has not been held during the

                demand given to the chief executive
                officer or chief financial officer.
                Within 30 days after receipt of the

TS BUSINESS     the shares of the trust issued and
TRUSTS          outstanding and entitled to vote
                constitutes a quorum at all meetings of

SELIGMAN        The presence in person or by proxy of
MARYLAND        the holders of record of one-third of
CORPORATIONS    the shares of all Series and classes
                issued and outstanding and entitled to

                except as otherwise provided by law or
                the articles of incorporation. Where
                the holders of shares of any Series or

                vote at the meeting constitutes a
                quorum for that vote.

                If a quorum is not present or
                represented at the meeting, the holders
                of a majority of the shares present in

                without notice other than announcement
                at the meeting, until a quorum is

                days after the original record date
                without notice other than announcement
                at the meeting. At any adjourned

                law or the Articles of Incorporation,
                for action upon any given matter will
                not prevent action of such meeting upon

                number of shares required for action in
                respect of such other matter or
                matters. Notwithstanding any provision
                of law requiring any action to be taken

                will be valid and effective if taken or
                authorized by the affirmative vote of

                The stockholders present either in
                person or by proxy, at a meeting which
                has been duly called and convened, may
                continue to transact business until
                adjournment, notwithstanding the
                withdrawal of enough stockholders to
                leave less than a quorum.

RIVERSOURCE     The holders of at least 10% of the
MINNESOTA       shares outstanding and entitled to
CORPORATIONS    vote, present in person or by proxy,
                constitute a quorum, but the holders of

                further notice, other than by notice at
                the time, until a quorum is secured at
                any such adjourned meeting. In case a

                be adjourned without notice other than
                by notice at the meeting. At any

                be present, any business may be
                transacted which might have been

SHAREHOLDER CONSENT

SELIGMAN        Under the MGCL, a majority of the
MARYLAND        entire board of directors of the
CORPORATIONS    corporation proposing to dissolve the
                corporation shall (1) adopt a
                resolution which declares that
                dissolution of the corporation is
                advisable; and (2) direct that the
                proposed dissolution be submitted for
                consideration at either an annual or a
                special meeting of the stockholders.
                Under the MGCL, unless the
                corporation's charter provides a lesser
                proportion of votes, but in no case
                less than a majority of all votes
                entitled to be cast on the proposal,
                the proposed dissolution shall be
                approved by the stockholders of the
                corporation by the affirmative vote of
                two-thirds of all the votes entitled to
                be cast on the matter. Each Seligman
                Fund's charter provides that
                notwithstanding any provision of law
                requiring any action to be taken or
                authorized by the holders of a greater
                proportion than a majority of the
                shares of all series and classes or of
                the shares of a particular series,
                class or classes, as the case may be,
                entitled to vote thereon, such action
                shall be valid and effective if taken
                or authorized by the affirmative vote
                of the holders of a majority of the
                shares of all series and classes or of
                such particular series, class or
                classes, as the case may be,
                outstanding and entitled to vote
                thereon.
- -------------------------------------------------------
RIVERSOURCE     In order to dissolve a Minnesota
MINNESOTA       corporation, the affirmative vote of a
CORPORATIONS    majority of the voting power of all
                shares entitled to vote is required. In
                order to discontinue an individual
                class or series of shares without
                dissolving the corporation, an
                amendment to the corporation's Articles
                of Incorporation is required. In order
                to adopt such an amendment,
                shareholders must approve the amendment
                by the affirmative vote of the greater
                of (i) a majority of the voting power
                of the shares of that class or series
                present and entitled to vote or (ii) a
                majority of the voting power of the
                minimum number of shares of such class
                or series entitled to vote that would
                constitute a quorum for the transaction
                of business at the meeting (a
                "Minnesota Statutory Vote").

                The board of directors, acting without
                a shareholder vote, does not have the
                power to dissolve the corporation or to
                discontinue an individual class or
                series of shares.

MERGER OR CONSOLIDATION OF TRUST / CORPORATION
- -------------------------------------------------------
SELIGMAN        Any merger, consolidation or sale or
MASSACHUSET-    exchange of assets of the trust
TS BUSINESS     requires the affirmative vote of at
TRUSTS          least two-thirds of shares outstanding
                and entitled to vote, or by an
                instrument(s) in writing without a
                meeting, consented to by the holders of
                not less than two-thirds of shares
                outstanding and entitled to vote, or by
                such other vote as may be established
                by the trustees with respect to any
                series or class of shares; provided,
                however, that, if such merger or
                consolidation is recommended by the
                trustees, then a majority shareholder
                vote shall be sufficient authorization.

                With respect to any merger or
                consolidation, all shareholders are
                entitled to the same appraisal rights
                as a stockholder of a Massachusetts
                business corporation. In the event of a
                merger, consolidation, sale or exchange
                of assets, appraisal rights will be the
                exclusive remedy for any dissenting
                shareholder.
- -------------------------------------------------------
SELIGMAN        Under the MGCL, unless the
MARYLAND        corporation's charter provides a lesser
CORPORATIONS    proportion of votes, but in no case
                less than a majority of all votes
                entitled to be cast on the proposal,
                any consolidation, merger, share
                exchange, or transfer requires the
                affirmative vote of two-thirds of all
                the votes entitled to be cast on the
                matter. Each Seligman Fund's charter
                provides that notwithstanding any
                provision of law requiring any action
                to be taken or authorized by the
                holders of a greater proportion than a
                majority of the shares of all series
                and classes or of the shares of a
                particular series, class or classes, as
                the case may be, entitled to vote
                thereon, such action shall be valid and
                effective if taken or authorized by the
                affirmative vote of the holders of a
                majority of the shares of all series
                and classes or of such particular
                series, class or classes, as the case
                may be, outstanding and entitled to
                vote thereon. A stockholder who has not
                received payment for his stock in
                connection with a merger,
                consolidation, share exchange or
                transfer may petition a court of equity
                in the county where the principal
                office of the corporation is located or
                where the resident agent of the
                successor is located, for an appraisal
                to determine the fair value of the
                stock.
- -------------------------------------------------------
RIVERSOURCE     In most cases, any merger or exchange
MINNESOTA       in which a Minnesota corporation is not
CORPORATIONS    the continuing entity, and any sale of
                all or substantially all of the
                corporation's property and assets not
                in the usual and regular course of its
                business, requires the affirmative vote
                of a majority of the voting power of
                all shares entitled to vote.

                Any sale of the assets belonging to an
                individual series of shares of a
                Minnesota corporation in exchange for
                shares of another corporation or trust
                or shares of another series of the
                corporation, while leaving other series
                of the corporation outstanding, would
                require an amendment to the
                corporation's Articles of
                Incorporation. In order to adopt such
                an amendment, shareholders of that
                series would have to approve the
                amendment by a Minnesota Statutory
                Vote.

REMOVAL OF DIRECTORS / TRUSTEES
- -------------------------------------------------------
SELIGMAN        Any of the trustees may be removed
MASSACHUSET-    (provided the aggregate number of
TS BUSINESS     trustees after removal is not less than
TRUSTS          two) with cause, by the consent of two-
                thirds of the remaining trustees.

                Upon the incapacity or death of any
                trustee, his legal representative must
                execute and deliver on his behalf all
                documents demanded by the remaining
                trustees.
- -------------------------------------------------------
SELIGMAN        Under the MGCL, stockholders of the
MARYLAND        corporation may remove any director,
CORPORATIONS    with or without cause, by the
                affirmative vote of a majority of all
                the votes entitled to be cast generally
                for the election of directors.

- -------------------------------------------------------
RIVERSOURCE     Under Minnesota law, the board of
MINNESOTA       directors can remove a director by a
CORPORATIONS    majority vote of the remaining
                directors, but only if the director was
                appointed by the board of directors to
                fill a vacancy and has not subsequently
                been elected by shareholders.

                In all other cases, a director can only
                be removed by shareholder vote. In
                general, such removal requires the
                affirmative vote of the holders of a
                majority of the voting power of all
                shares entitled to vote at an election
                of directors. However, where a
                corporation has cumulative voting (as
                do the Funds), unless the entire board
                of directors is removed simultaneously,
                a director is not removed from the
                board of directors if there are cast
                against removal of the director the
                votes of a proportion of the voting
                power sufficient to elect the director
                at an election of the entire board of
                directors under cumulative voting.

DIRECTOR / TRUSTEE COMMITTEES
- -------------------------------------------------------
SELIGMAN        The trustees, by the majority vote of
MASSACHUSET-    all the trustees, may appoint from the
TS BUSINESS     trustees committees which must consist
TRUSTS          of at least two trustees and will have
                and may exercise powers as the trustees
                may determine in the resolution
                appointing them.

                A majority of all the members of any
                committee may determine its action and
                fix the time and place of its meetings,
                unless the trustees otherwise provide.
                The trustees have power at any time to
                change the members and powers of any
                such committee, to fill vacancies and
                to discharge any such committee.

                serve at the pleasure of the Board of
                Directors. Any director may give notice
                to the Board of Directors at any time
                of his or her resignation from any
                committee on which he or she serves.

                The Board of Directors may delegate to
                committees appointed pursuant to the
                articles of incorporation any of the
                powers of the Board of Directors,
                except as prohibited by law.

                Any action required or permitted to be
                taken at any meeting of a committee of
                the Board of Directors may be taken
                without a meeting, if a consent to such
                action in writing or by electronic
                transmission is given by each member of
                the committee and filed with the
                minutes of proceedings of such
                committee.

                Subject to the previous sections, the
                Board of Directors has the power at any
                time to change the membership of any
                committee, to fill all vacancies, to
                designate alternate members to replace
                any absent or disqualified member or to
                dissolve any such committee. Subject to
                the power of the Board of Directors,
                the members of a committee have the
                power to fill any vacancies on such

                directors, appoint any other committee
                or committees for any purpose or
                purposes, which committee or committees
                will have such powers as specified in
                the resolution of appointment.

                The corporation's By-Laws provide that
                the board of directors may, by
                resolution passed by a majority of the
                whole board of directors, designate an
                Executive Committee of two or more
                directors, which may meet at stated
                times or on notice to all by any of
                their number during intervals between
                meetings of the board of directors. The
                Executive Committee will advise with
                and aid the officers of the Fund in all
                matters concerning its interests and
                the management of its business, and
                generally perform such duties and
                exercise such powers as may be
                delegated to it from time to time by
                the board of directors.

                The board of directors also may, by
                resolution passed by a majority of the
                whole board of directors, appoint any
                other committee or committees for any
                purpose or purposes, which committee or
                committees will have such powers as
                specified in the resolution of
                appointment. The quorum for such
                committee established by the board of
                directors is two members regardless of
                the number of members serving on the
                committee. Under Minnesota law, the
                members of such other committees do not
                need to be directors.

TRUSTS          with the trust property or the affairs

                any breach of trust. All persons must

                arising in connection with the affairs

SELIGMAN        The Fund's Articles of Incorporation
MARYLAND        provide that a director or officer of
CORPORATIONS    the corporation will not be liable to

                officer, except to the extent such
                exemption from liability or limitation
                thereof is not permitted by law
                (including the 1940 Act).

                Under the MGCL, the foregoing provision
                is not effective to eliminate a
                director's personal liability to the
                Funds or its shareholders for, among
                other things, any act or omission of

                believe that the act or omission was
                unlawful.

                Under the MGCL, the charter of a
                Maryland corporation may include any

                final adjudication adverse to the
                person is entered in a proceeding based
                on a finding in the proceeding that the

                the result of active and deliberate
                dishonesty and was material to the

DIRECTOR / TRUSTEE INDEMNIFICATION
- -------------------------------------------------------
SELIGMAN        A representative of the trust will be
MASSACHUSET-    indemnified by the trust with respect
TS BUSINESS     to each proceeding against him or her,
TRUSTS          except for a proceeding brought by or
                on behalf of the trust, against
                expenses (including attorneys' fees),
                judgments, fines and amounts paid in
                settlement actually and reasonably
                incurred by the representative in
                connection with the proceeding,
                provided that the representative acted
                in good faith and in a manner he
                reasonably believed to be in or not
                opposed to the best interests of the
                trust and, with respect to any criminal
                proceeding, had no reasonable cause to
                believe his conduct was unlawful. The
                termination of any proceeding by
                judgment, order, settlement, conviction
                or upon a plea of nolo contendere or
                its equivalent, does not, of itself,
                create a presumption that the person
                did not act in good faith and in a
                manner in which he reasonably believed
                to be in or not opposed to the best
                interests of the trust and, with
                respect to any criminal proceeding, had
                reasonable cause to believe that his
                conduct was unlawful.

                A representative of the trust will be
                indemnified by the trust, with respect
                to each proceeding brought by or on
                behalf of the trust to obtain a
                judgment or decree in its favor,
                against expenses (including attorneys'
                fees) actually and reasonable incurred
                by him in connection with the defense
                or settlement of such proceeding, if he
                acted in good faith and in a manner he
                reasonably believed to be in or not
                opposed to the best interests of the
                trust; except that no indemnification
                will be made in respect of any claim,
                issue, or matter as to which such
                representative has been adjudged to be
                liable for negligence or misconduct in
                the performance of his duty to the
                trust, unless and only to the extent
                that the court in which the proceeding
                was brought, or a court of equity in
                the county in which the trust has its
                principal office, despite the
                adjudication of liability but in view
                of all circumstances of the case, the
                representative is fairly and reasonably
                entitled to indemnity for the expenses
                which the court considers proper.

                To the extent that the representative
                of the trust has been successful on the
                merits or otherwise in defense of any
                proceeding referred to in the preceding
                two paragraphs, or in defense of any
                claim, issue or matter therein, the
                trust will indemnify him against all
                expenses (including attorneys' fees)
                actually and reasonably incurred by him
                in connection with the proceeding.

                Except as provided above, any
                indemnification under the first two
                provisions of this section (unless
                ordered by a court) will be made by the
                trust only as authorized in the
                specific case upon a determination that
                indemnification of the representative
                of the trust is proper in the
                circumstances because he has met the
                applicable standard of conduct set
                forth in the paragraphs. The
                determination will be made (1) by the
                trustees by a majority vote of a quorum
                consisting of trustees who were not
                parties to the proceeding, or (2) if a
                quorum is not obtainable or if a quorum
                of disinterested trustees so directs,
                by independent legal counsel in a
                written opinion, or (3) by the
                shareholders.

                Expenses (including attorneys' fees)
                incurred in defending a proceeding may
                be paid by the trust in advance of the
                final disposition if (1) authorized by
                the trustees in the specific case, and
                (2) the trust receives and undertaking
                by or on behalf of the representative
                of the trust to repay the advance if it
                is not ultimately determined that he is
                entitled to the indemnified by the
                trust as authorized by the above.

                The indemnification provided above is
                not exclusive of any other rights that
                a representative of the trust or other
                person may be entitled under any
                agreement, vote of shareholders or
                disinterested trustees or otherwise,
                both as to action in his official
                capacity and as to action in another
                capacity while holding the office, and
                will continue as to a person who has
                ceased to be a trustee, officer,
                employee or agent and inure to the
                benefit of his heirs and personal
                representatives.

SELIGMAN        The corporation will indemnify to the
MARYLAND        fullest extent permitted by law any
CORPORATIONS    person made or threatened to be made a
                party to any action, suit or
                proceeding, whether criminal, civil,
                administrative or investigative, by
                reason of the fact that such person is
                or was a director, officer or employee
                of the corporation or serves or served
                at the request of the corporation any
                other enterprise as a director, officer
                or employee. To the fullest extent
                permitted by law, expenses incurred by
                any such person in defending any such
                action, suit or proceeding will be paid
                or reimbursed by the corporation
                promptly, provided that such person
                agrees to repay such expenses if it is
                ultimately determined that such person
                is not entitled to be indemnified by
                the corporation. The articles of
                incorporation may not be amended to
                adversely affect this protection. These
                provisions do not waive compliance with
                the Securities Act of 1933 or the 1940
                Act or other valid rule, regulation or
                order of the SEC.

                Under the MGCL, a corporation may
                indemnify a director made a party to
                any Proceeding by reason of service in
                that capacity unless found liable under
                provisions (1) and (2) under "Director/
                Trustee Liability". Indemnification may
                be against judgments, penalties, fines,
                settlements, and reasonable expenses
                actually incurred by the director in
                connection with the proceeding.
                However, if the proceeding was one by
                or in the right of the corporation,
                indemnification may not be made in
                respect of any proceeding in which the
                director shall have been adjudged to be
                liable to the corporation.

                The Corporation's By-Laws provide to
                the maximum extent permitted by
                Maryland law, as in effect from time to
                time, the Corporation shall indemnify
                and, without requiring a preliminary
                determination of the ultimate
                entitlement to indemnification, shall
                pay or reimburse reasonable expenses in
                advance of final disposition of a
                proceeding to (a) any individual who is
                a present or former director or officer
                of the Corporation and who is made, or
                threatened to be made, a party to the
                proceeding by reason of his or her
                service in any such capacity or (b) any
                individual who, while a director or
                officer of the Corporation and at the
                request of the Corporation, serves or
                has served as a director, officer,
                partner or trustee of another
                corporation, or a real estate
                investment trust, partnership, joint
                venture, trust, employee benefit plan
                or other enterprise and who is made, or
                threatened to be made, a party to the
                proceeding by reason of his or her
                service in any such capacity. The
                Corporation may, with the approval of
                its Board of Directors or any duly
                authorized committee thereof, provide
                such indemnification and advance for
                expenses to a person who served a
                predecessor of the Corporation in any
                of the capacities described in (a) or
                (b) above and to any employee or agent
                of the Corporation or a predecessor of
                the Corporation. The termination of any
                claim, action, suit or other proceeding
                involving any person, by judgment,
                settlement (whether with or without
                court approval) or conviction or upon a
                plea of guilty or nolo contendere, or
                its equivalent, shall not create a
                presumption that such person did not
                meet the standards of conduct required
                for indemnification or payment of
                expenses to be required or permitted
                under Maryland law, the By-laws or the

RIVERSOURCE     The Fund will indemnify any person who
MINNESOTA       was or is a party and is threatened to
CORPORATIONS    be made a party, by reason of the fact
                that she or he is or was a director,
                officer, employee or agent of the Fund,
                or is or was serving at the request of
                the Fund as a director, officer,
                employee or agent of another company,
                partnership, joint venture, trust or
                other enterprise, to any threatened,
                pending or completed action, suit or
                proceeding, wherever brought, and the
                Fund may purchase liability insurance
                and advance legal expenses, all to the
                fullest extent permitted by the laws of
                the State of Minnesota. Any
                indemnification hereunder will not be
                exclusive of any other rights of
                indemnification to which the directors,
                officers, employees or agents might
                otherwise be entitled. No
                indemnification will be made in
                violation of the 1940 Act.

                Under Minnesota law, a corporation is
                required to indemnify and advance
                expenses to present and former
                directors against judgments, penalties,
                fines, settlements and reasonable
                expenses, including attorneys' fees and
                disbursements, if they are made parties
                to a legal proceeding by virtue of
                their position as directors. However,
                indemnification and advances are not
                required or permitted if a director
                engaged in specified disabling conduct.

                The corporation's Articles of
                Incorporation and By-Laws provide that
                each person made or threatened to be
                made a party to or who is involved
                (including, without limitation, as a
                witness) in any actual or threatened
                action, suit or proceeding whether
                civil, criminal, administrative,
                arbitration, or investigative,
                including a proceeding by or in the
                right of the Fund by reason of the
                former or present capacity as a
                director or officer of the Fund or who,
                while a director or officer of the
                Fund, is or was serving at the request
                of the Fund or whose duties as a
                director or officer involve or involved
                service as a director, officer,
                partner, trustee or agent of another
                organization or employee benefit plan,
                whether the basis of any proceeding is
                alleged action in an official capacity
                or in any capacity while serving as a
                director, officer, partner, trustee or
                agent, will be indemnified and held
                harmless by the Fund to the full extent
                authorized by laws of the State of
                Minnesota, as the same or may hereafter
                be amended (but, in the case of any
                such amendment, only to the extent that
                such amendment permits the Fund to
                provide broader indemnification rights
                than the law permitted the Fund to
                provide prior to such amendment), or by
                any other applicable law as then in
                effect, against judgments, penalties,
                fines including, without limitation,
                excise taxes assessed against the
                person with respect to an employee
                benefit plan, settlements and
                reasonable expenses, including
                attorneys' fees and disbursements,
                incurred in connection therewith and
                the indemnification will continue as to
                any person who has ceased to be a
                director or officer and will inure to
                the benefit of the person's heirs,
                executors and administrators provided,
                however, in an action brought against
                the Fund to enforce rights to
                indemnification, the director or
                officer will be indemnified only if the
                action was authorized by the board of
                directors of the Fund. The right to
                indemnification conferred by these
                provisions is a contract right and
                includes the right to be paid by the
                Fund in advance of the final
                disposition of a proceeding for
                expenses incurred in connection
                therewith provided, however, such
                payment of expenses will be made only
                upon receipt of a written undertaking
                by the director or officer to repay all
                amounts so paid if it is ultimately
                determined that the director or officer
                is not entitled to indemnification.

                Each person who upon written request to
                the Funds has not received payment
                within thirty days may at any time
                thereafter bring suit against the Funds
                to recover any unpaid amount and, to
                the extent successful, in whole or in
                part, will be entitled to be paid the
                expenses of prosecuting such suit. Each
                person will be presumed to be entitled
                to indemnification upon filing a
                written request for payment and the
                Fund will have the burden of proof to
                overcome the presumption that the
                director or officer is not so entitled.
                Neither the determination by the Fund,
                whether by the board of directors,
                special legal counsel or by
                shareholder, nor the failure of the
                Fund to have made any determination
                will be a defense or create the
                presumption that the director or
                officer is not entitled to
                indemnification.

                The right to indemnification and to the
                payment of expenses prior to any final
                determination will not be exclusive of
                any other right which any person may
                have or hereinafter acquire under any
                statute, provision of the Articles of
                Incorporation, By-Law, agreement, vote
                of shareholders or otherwise and
                notwithstanding any provisions in the
                Funds' By-Laws, the Funds are not
                obligated to make any payment with
                respect to any claim for which payment
                is required to be made to or on behalf
                of the director or officer under any
                insurance policy, except with respect
                to any excess beyond the amount of
                required payment under such insurance
                and no indemnification will be made in
                violation of the provisions of the 1940
                Act.

                improper purpose for requesting the
                inspection.

HERE IS A BRIEF OVERVIEW OF THE CHANGES BEING RECOMMENDED FOR YOUR FUND. WE
ENCOURAGE YOU TO READ THE FULL TEXT OF THE ENCLOSED COMBINED PROXY
STATEMENT/PROSPECTUS.

Q:   WHY AM I BEING ASKED TO VOTE?

Mutual funds are required to get shareholders' approval for certain kinds of
changes, like the proposals in this combined proxy statement/prospectus.

Q:   IS MY VOTE IMPORTANT?

Absolutely! While the Board of Directors/Trustees (the "Board" or the "Board of
Directors/Trustees") of each Fund listed above has reviewed these proposals and
recommends that you approve them, you have the right to voice your opinion.
Until a Fund is sure that a quorum has been reached, it will continue to contact
shareholders asking them to vote.

Q:   WHAT AM I BEING ASKED TO VOTE ON?

Shareholders are being asked to vote on:

THE REORGANIZATION PROPOSALS:

The reorganization (each a "Reorganization") of each Selling Fund (each a
"Selling Fund" and together, the "Selling Funds") into its corresponding Buying
Fund (each a "Buying Fund" and together, the "Buying Funds"), as noted in the
table below:

<Table>
<Caption>
SELLING FUND                                    BUYING FUND
                                             
Seligman Core Fixed Income Fund, Inc.           RiverSource Diversified Bond Fund
Seligman Emerging Markets Fund                  Threadneedle Emerging Markets Fund
Seligman Global Growth Fund                     Threadneedle Global Equity Fund
Seligman High-Yield Fund                        RiverSource High Yield Bond Fund
Seligman Income and Growth Fund, Inc.           RiverSource Balanced Fund
Seligman International Growth Fund              RiverSource Partners International Select
                                                Growth Fund
Seligman U.S. Government Securities Fund        RiverSource Short Duration U.S. Government
                                                Fund
</Table>


If the Reorganization of your Selling Fund is approved by shareholders and the
other closing conditions are met, your shares of the Selling Fund will, in
effect, be converted into shares of the corresponding Buying Fund with the same
aggregate net asset value as your Selling Fund shares at the time of the
Reorganization. (Selling Funds and Buying Funds may be individually or
collectively referred to as a "Fund" or the "Funds.")

THE MANAGER OF MANAGERS PROPOSALS:

Shareholders of each of Seligman Emerging Markets Fund, Seligman Global Growth
Fund and Seligman International Growth Fund (each a "Seligman Subadvised Fund"
and together the "Seligman Subadvised Funds") are being asked to consider a
proposal to approve a policy authorizing RiverSource Investments, LLC
("RiverSource Investments" or the "investment manager"), the Seligman Subadvised
Funds' investment adviser, with the approval of the Board, to retain and to
replace subadvisers, or to modify subadvisory agreements, without obtaining
shareholder approval (each a "Manager of Managers Proposal" and together the
"Manager of Managers Proposals"). The approval of each Manager of Managers
Proposal will eliminate the need for shareholder meetings and related proxy
solicitation if the Board determines that such retention, replacement or
modification is appropriate, thereby reducing associated delays and costs.



We encourage you to read the full text of the combined proxy
statement/prospectus to obtain a more detailed understanding of the issues.

Q:   WHY ARE THE REORGANIZATIONS BEING PROPOSED?

RiverSource Investments, a wholly-owned subsidiary of Ameriprise Financial, Inc.
and the investment manager of the RiverSource Funds, recently purchased all of
the outstanding capital stock of J. & W. Seligman & Co. Incorporated
("Seligman"), the former investment manager of the Seligman Funds, and became
the investment manager of the Seligman Funds. In connection with the purchase of
Seligman, the RiverSource Family of Funds now includes the Seligman Funds in
addition to funds branded "RiverSource," "RiverSource Partners" and
"Threadneedle". RiverSource Investments has proposed that the Selling Funds be
reorganized into the Buying Funds. The Reorganization of each Selling Fund into
the corresponding Buying Fund would result in a larger combined fund with the
same or similar investment objectives, principal investment strategies and
fundamental investment policies, which will allow for more focused distribution,
potentially increasing sales of and economies of scale in the combined fund.
Additionally, following each Reorganization, expenses of the larger combined
fund are expected to be lower than the expenses would have been for the Selling
Fund.

Q:   IF APPROVED, WHEN WILL THE REORGANIZATIONS HAPPEN?

The Reorganizations will take place as soon as practicable following shareholder
approval, and are expected to close before the end of the third quarter of 2009.

Q:   HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THE REORGANIZATION PROPOSALS?

After careful consideration, the Board of each Selling Fund recommends that you
vote FOR the Reorganization of your Selling Fund.

Q:   WHY ARE THE MANAGER OF MANAGERS PROPOSALS BEING PROPOSED?

As explained above, in connection with its recent purchase of all of the
outstanding capital stock of Seligman, RiverSource Investments became the
investment manager of each of the Seligman Subadvised Funds. Shareholders of the
Seligman Subadvised Funds are being asked to approve the Manager of Managers
Proposals in order to conform the Seligman Subadvised Funds' policies in this
respect to the policies of the other funds in the RiverSource Family of Funds.
The Manager of Managers Proposals will allow the investment manager, with the
oversight and approval of the Board, the flexibility to appoint new subadvisers
and/or materially modify subadvisory agreements without the delay and cost
associated with holding a shareholder meeting.

Q:   HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THE MANAGER OF MANAGER
     PROPOSALS?

After careful consideration, the Board of each Seligman Subadvised Fund
recommends that you vote FOR the Manager of Managers proposal for your Seligman
Subadvised Fund.

Q:   HOW DO I VOTE?

You can vote in one of four ways:

- -  By telephone

- -  By internet

- -  By mail with the enclosed proxy card

- -  In person at the meeting

Please refer to the enclosed proxy card for the telephone number and internet
address.

Q:   WHOM SHOULD I CALL IF I HAVE QUESTIONS?

If you have questions about any of the proposals described in the combined proxy
statement/prospectus or about voting procedures, please call the Funds' proxy
solicitor, Computershare Fund Services, toll free at (866) 438-8932.

RIVERSOURCE HIGH YIELD BOND FUND (BUYING FUND)

SELIGMAN HIGH-YIELD FUND (SELLING FUND)

INTRODUCTION TO PROPOSED FUND REORGANIZATION

Nov. 30, 2008

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two
Funds at, and for, the 12-month period ended Nov. 30, 2008. These statements
have been derived from financial statements prepared for the RiverSource High
Yield Bond Fund and the Seligman High-Yield Fund as of Nov. 30, 2008.
RiverSource High Yield Bond Fund invests primarily in high-yield debt
instruments including corporate debt securities and bank loans rated below
investment grade and may invest up to 25% of the Fund's net assets in high-yield
debt instruments of foreign issuers. Seligman High-Yield Fund invests primarily
in non-investment grade, high-yield securities which carry non-investment grade
ratings or are securities deemed to be below investment grade by RiverSource
Investments, LLC (the investment manager).

Under the proposed Agreement and Plan of Reorganization, share classes of
Seligman High-Yield Fund would be exchanged for share classes of RiverSource
High Yield Bond Fund.

RIVERSOURCE HIGH YIELD BOND FUND (BUYING FUND)

SELIGMAN HIGH-YIELD FUND (SELLING FUND)

NOTES TO PRO FORMA FINANCIAL STATEMENTS
(Unaudited as to Nov. 30, 2008)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the two Funds at, and for, the
12-month period ended Nov. 30, 2008. These statements have been derived from
financial statements prepared for the RiverSource High Yield Bond Fund and the
Seligman High-Yield Fund as of Nov. 30, 2008.

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments
of each Fund are as follows:

RiverSource High Yield Bond Fund invests primarily in high-yield debt
instruments including corporate debt securities and bank loans rated below
investment grade and may invest up to 25% of the Fund's net assets in high-yield
debt instruments of foreign issuers.

Seligman High-Yield Fund invests primarily in non-investment grade, high-yield
securities which carry non-investment grade ratings or are securities deemed to
be below investment grade by RiverSource Investments, LLC (the investment
manager).

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of Seligman High-Yield Fund in exchange for Class A, Class B, Class
C, Class R2 and Class R5 shares of RiverSource High Yield Bond Fund under U.S.
generally accepted accounting principles. The pro forma statements reflect
estimates for the combined RiverSource High Yield Bond Fund based on the
increased asset level of the Reorganization and associated economies of scale,
adjusted to reflect current fees.

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

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

2. PRO FORMA ADJUSTMENTS

(a) To reflect the change in investment management services fee due to the
    Reorganization.

(b) To reflect the change in transfer agent fees due to the Reorganization
    including adjusting for closed account fees for each Seligman High-Yield
    Fund shareholder account that will be closed on the system as a result of
    the Reorganization.

(c) To reflect the change in administrative services fees due to the
    Reorganization.

(d) To reflect the change in plan administration services fees due to the
    Reorganization.

(e) To reflect the change in other fees due to the Reorganization.

(f) To adjust the expense reimbursement to reflect the net reduction in fees
    resulting from the Reorganization per the agreement (through May 31, 2009)
    by RiverSource Investments, LLC and its affiliates to waive certain fees and
    absorb certain expenses of the combined fund.

(g) Includes the impact of estimated Reorganization costs of $133,709, none of
   which are recurring expenses.


                                        6

 NOTES TO COMBINED PORTFOLIO OF INVESTMENTS

</Table>



    (A) Securities are valued by procedures described in Note 1 to the financial
        statements in the annual report.

    (B) Non-income producing. For long-term debt securities, item identified is
        in default as to payment of interest and/or principal.

    (C) Foreign security values are stated in U.S. dollars. For debt securities,
        principal amounts are denominated in U.S. dollar currency unless
        otherwise noted. At Nov. 30, 2008, the value of foreign securities
        represented 3.3% of net assets.

    (D) Represents a security sold under Rule 144A, which is exempt from
        registration under the Securities Act of 1933, as amended. This security
        has been determined to be liquid under guidelines established by the
        Fund's Board of Directors. These securities may be resold in
        transactions exempt from registration, normally to qualified
        institutional buyers. At Nov. 30, 2008, the value of these securities
        amounted to $160,159,644 of 15.9% of net assets.

    (E) The share amount for Limited Liability Companies (LLC) or Limited
        Partnerships (LP) represents capital contributions.

    (F) Mortgage-backed securities represent direct or indirect participations
        in, or are secured by and payable from, mortgage loans secured by real
        property, and include single- and multi-class pass-through securities
        and collateralized mortgage obligations. These securities may be issued
        or guaranteed by U.S. government agencies or instrumentalities, or by
        private issuers, generally originators and investors in mortgage loans,
        including savings associations, mortgage bankers, commercial banks,
        investment bankers and special purpose entities. The maturity dates
        shown represent the original maturity of the underlying obligation.
        Actual maturity may vary based upon prepayment activity on these
        obligations. Unless otherwise noted, the coupon rates presented are
        fixed rates.

    (G) At Nov. 30, 2008, the cost of securities purchased, including interest
        purchased, on a when-issued and/or other forward-commitment basis was
        $41,979,589.

    (H) Senior loans have rates of interest that float periodically based
        primarily on the London Interbank Offered Rate ("LIBOR") and other
        short-term rates. Remaining maturities of senior loans may be less than
        the stated maturities shown as a result of contractual or optional
        prepayments by the borrower. Such prepayments cannot be predicted with
        certainty.

    (I) Interest rate varies either based on a predetermined schedule or to
        reflect current market conditions; rate shown is the effective rate on
        Nov. 30, 2008.


                                       19

  * The original cost for this position in fiscal year 2004 was $25,000,000.
    From Sept. 29, 2004 through March 7, 2005, $25,000,000 was returned to the
    fund in the form of return of capital.

    (L) Security valued by management at fair value according to procedures
        approved, in good faith, by the Board.

    (M) For those zero coupon bonds that become coupon paying at a future date,
        the interest rate disclosed represents the annualized effective yield
        from the date of acquisition to maturity.

    (N) Pay-in-kind securities are securities in which the issuer makes interest
        or dividend payments in cash or in additional securities. The securities
        usually have the same terms as the original holdings.

    (O) On Sept. 15, 2008, Lehman Brothers Holdings filed a Chapter 11
        bankruptcy petition.

    (P) Represents a senior loan purchased on a when-issued or delayed-delivery
        basis. Certain details associated with this purchase are not known prior
        to the settlement date of the transaction. In addition, senior loans
        typically trade without accrued interest and therefore a weighted
        average coupon rate is not available prior to settlement. At settlement,
        if still unknown, the borrower or counterparty will provide the Fund
        with the final weighted average coupon rate and maturity date.

    (Q) At Nov. 30, 2008, the Fund had unfunded senior loan commitments pursuant
        to the term of the loan agreement. The Fund receives a stated coupon
        rate until the borrower draws on the loan commitment, at which time the
        rate will become the stated rate in the loan agreement.

INTRODUCTION TO PROPOSED FUND REORGANIZATION

Oct. 31, 2008

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two
Funds at, and for, the 12-month period ended Oct. 31, 2008. These statements
have been derived from financial statements prepared for the RiverSource
Partners International Select Growth Fund and the Seligman International Growth
Fund as of Oct. 31, 2008. RiverSource Partners International Select Growth Fund
invests primarily in equity securities of foreign issuers, in both developed and
emerging markets, that are believed to offer strong growth potential. Seligman
International Growth Fund invests primarily in high-quality, large- and mid-
capitalization growth companies with a market capitalization of $1 billion or
more at the time of purchase and will invest in any country; however, it
typically will not invest in the United States.

Under the proposed Agreement and Plan of Reorganization, share classes of
Seligman International Growth Fund would be exchanged for share classes of
RiverSource Partners International Select Growth Fund.

RIVERSOURCE PARTNERS INTERNATIONAL SELECT GROWTH FUND (BUYING FUND)

SELIGMAN INTERNATIONAL GROWTH FUND (SELLING FUND)

NOTES TO PRO FORMA FINANCIAL STATEMENTS
(Unaudited as to Oct. 31, 2008)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the two Funds at, and for, the
12-month period ended Oct. 31, 2008. These statements have been derived from
financial statements prepared for the RiverSource Partners International Select
Growth Fund and the Seligman International Growth Fund as of Oct. 31, 2008.

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments
of each Fund are as follows:

RiverSource Partners International Select Growth Fund invests primarily in
equity securities of foreign issuers, in both developed and emerging markets,
that are believed to offer strong growth potential.

Seligman International Growth Fund invests primarily in high-quality, large- and
mid-capitalization growth companies with a market capitalization of $1 billion
or more at the time of purchase and will invest in any country; however, it
typically will not invest in the United States.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of Seligman International Growth Fund in exchange for Class A, Class
B, Class C, Class R2 and Class R5 shares of RiverSource Partners International
Select Growth Fund under U.S. generally accepted accounting principles. The pro
forma statements reflect estimates for the combined RiverSource Partners
International Select Growth Fund based on the increased asset level of the
Reorganization and associated economies of scale, adjusted to reflect current
fees.

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

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

2. PRO FORMA ADJUSTMENTS

(a) To reflect the change in investment management services fee due to the
    Reorganization. In addition, the Performance Incentive Adjustment (PIA) was
    calculated based on the combined average net assets of the two funds and the
    RiverSource Partners International Select Growth Fund PIA rate as of Oct.

Nov. 30, 2008

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two
Funds at, and for, the 12-month period ended Nov. 30, 2008. These statements
have been derived from financial statements prepared for the RiverSource Short
Duration U.S. Government Fund and the Seligman U.S. Government Securities Fund
as of Nov. 30, 2008. RiverSource Short Duration U.S. Government Fund invests
primarily in debt securities issued or guaranteed as to principal and interest
by the U.S. government, or its agencies or instrumentalities. Seligman U.S.
Government Securities Fund invests primarily in U.S. government securities which
are debt securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities, or government sponsored enterprises.

Under the proposed Agreement and Plan of Reorganization, share classes of
Seligman U.S. Government Securities Fund would be exchanged for share classes of
RiverSource Short Duration U.S. Government Fund.

RIVERSOURCE SHORT DURATION U.S. GOVERNMENT FUND (BUYING FUND)

SELIGMAN U.S. GOVERNMENT SECURITIES FUND (SELLING FUND)

NOTES TO PRO FORMA FINANCIAL STATEMENTS
(Unaudited as to Nov. 30, 2008)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the two Funds at, and for, the
12-month period ended Nov. 30, 2008. These statements have been derived from
financial statements prepared for the RiverSource Short Duration U.S. Government
Fund and the Seligman U.S. Government Securities Fund as of Nov. 30, 2008.

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments
of each Fund are as follows:

RiverSource Short Duration U.S. Government Fund invests primarily in debt
securities issued or guaranteed as to principal and interest by the U.S.
government, or its agencies or instrumentalities.

Seligman U.S. Government Securities Fund invests primarily in U.S. government
securities which are debt securities issued or guaranteed by the U.S.
government, its agencies or instrumentalities, or government sponsored
enterprises.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of Seligman U.S. Government Securities Fund in exchange for Class A,
Class B, Class C and Class R2 shares of RiverSource Short Duration U.S.
Government Fund under U.S. generally accepted accounting principles. The pro
forma statements reflect estimates for the combined RiverSource Short Duration
U.S. Government Fund based on the increased asset level of the Reorganization
and associated economies of scale, adjusted to reflect current fees.

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

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

2. PRO FORMA ADJUSTMENTS

(a) To reflect the change in investment management services fee due to the
    Reorganization.

(b) To reflect the change in transfer agent fees due to the Reorganization
    including adjusting for closed account fees for each Seligman U.S.
    Government Securities Fund shareholder account that will be closed on the
    system as a result of the Reorganization.

(c) To reflect the change in administrative services fees due to the
    Reorganization.

(d) To reflect the change in plan administration services fees due to the
    Reorganization.

(e) To reflect the change in other fees due to the Reorganization.

(f) To adjust the expense reimbursement to reflect the net reduction in fees
    resulting from the Reorganization per the agreement (through May 31, 2009)
    by RiverSource Investments, LLC and its affiliates to waive certain fees and
    absorb certain expenses of the combined fund.

(g) Includes the impact of estimated Reorganization costs of $80,918, none of
    which are recurring expenses.


                                       44

    (A) Securities are valued by using procedures described in Note 1 to the
        financial statements.

    (B) Interest only represents securities that entitle holders to receive only
        interest payments on the underlying mortgages. The yield to maturity of
        an interest only is extremely sensitive to the rate of principal
        payments on the underlying mortgage assets. A rapid (slow) rate of
        principal repayments may have an adverse (positive) effect on yield to
        maturity. The principal amount shown is the notional amount of the
        underlying mortgages. The interest rate disclosed represents yield based
        upon the estimated timing and amount of future cash flows at Nov. 30,
        2008.

    (C) Principal only represents securities that entitle holders to receive
        only principal payments on the underlying mortgages. The yield to
        maturity of a principal only is sensitive to the rate of principal
        payments on the underlying mortgage assets. A slow (rapid) rate of
        principal repayments may have an adverse (positive) effect on yield to
        maturity. Interest rate disclosed represents yield based upon the
        estimated timing of future cash flows at Nov. 30, 2008.

    (D) Represents a security sold under Rule 144A, which is exempt from
        registration under the Securities Act of 1933, as amended. This security
        has been determined to be liquid under guidelines established by the
        Fund's Board of Directors. These securities may be resold in
        transactions exempt from registration, normally to qualified
        institutional buyers. At Nov. 30, 2008, the value of these securities
        amounted to $6,561,576 or 0.7% of net assets.

    (E) At Nov. 30, 2008, the cost of securities purchased, including interest
        purchased, on a when-issued and/or other forward-commitment basis was
        $39,811,910.

    (F) Mortgage-backed securities represent direct or indirect participations
        in, or are secured by and payable from, mortgage loans secured by real
        property, and include single- and multi-class pass-through securities
        and collateralized mortgage obligations. These securities may be issued
        or guaranteed by U.S. government agencies or instrumentalities, or by
        private issuers, generally originators and investors in mortgage loans,
        including savings associations, mortgage bankers, commercial banks,
        investment bankers and special purpose entities. The maturity dates
        shown represent the original maturity of the underlying obligation.
        Actual maturity may vary based upon prepayment activity on these
        obligations. Unless otherwise noted, the coupon rates presented are
        fixed rates.

INTRODUCTION TO PROPOSED FUND REORGANIZATION

Oct. 31, 2008

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the two
Funds at, and for, the 12-month period ended Oct. 31, 2008. These statements
have been derived from financial statements prepared for the Threadneedle
Emerging Markets Fund and the Seligman Emerging Markets Fund as of Oct. 31,
2008. Threadneedle Emerging Markets Fund invests primarily in equity securities
of emerging markets companies or in companies that earn 50% or more of their
total revenues from goods or services produced in emerging market countries or
from sales made in emerging market countries. Seligman Emerging Markets Fund
invests primarily in equity securities of companies that conduct their principal
business activities in emerging markets, are organized under the laws of, or
maintain their principal place of business in emerging markets, or whose
securities are traded principally on exchanges in emerging markets.

Under the proposed Agreement and Plan of Reorganization, share classes of
Seligman Emerging Markets Fund would be exchanged for share classes of
Threadneedle Emerging Markets Fund.

THREADNEEDLE EMERGING MARKETS FUND (BUYING FUND)

SELIGMAN EMERGING MARKETS FUND (SELLING FUND)

NOTES TO PRO FORMA FINANCIAL STATEMENTS
(Unaudited as to Oct. 31, 2008)

1.  BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the two Funds at, and for, the
12-month period ended Oct. 31, 2008. These statements have been derived from
financial statements prepared for the Threadneedle Emerging Markets Fund and the
Seligman Emerging Markets Fund as of Oct. 31, 2008.

Each Fund is registered under the Investment Company Act of 1940 (as amended) as
a diversified, open-end management investment company. The primary investments
of each Fund are as follows:

Threadneedle Emerging Markets Fund invests primarily in equity securities of
emerging markets companies or in companies that earn 50% or more of their total
revenues from goods or services produced in emerging market countries or from
sales made in emerging market countries.

Seligman Emerging Markets Fund invests primarily in equity securities of
companies that conduct their principal business activities in emerging markets,
are organized under the laws of, or maintain their principal place of business
in emerging markets, or whose securities are traded principally on exchanges in
emerging markets.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of Seligman Emerging Markets Fund in exchange for Class A, Class B,
Class C, Class R2 and Class R5 shares of Threadneedle Emerging Markets Fund
under U.S. generally accepted accounting principles. The pro forma statements
reflect estimates for the combined Threadneedle Emerging Markets Fund based on
the increased asset level of the Reorganization and associated economies of
scale, adjusted to reflect current fees.

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

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

2.  PRO FORMA ADJUSTMENTS

(a) To reflect the change in investment management services fee due to the
    Reorganization. In addition, the Performance Incentive Adjustment (PIA) was
    calculated based on the combined average net assets of the two funds and the
    Threadneedle Emerging Markets Fund PIA rate as of Oct. 31, 2008.

(b) To reflect the change in transfer agent fees due to the Reorganization
    including adjusting for closed account fees for each Seligman Emerging
    Markets Fund shareholder account that will be closed on the system as a
    result of the Reorganization.

(c) To reflect the change in administrative services fees due to the
    Reorganization.

(d) To reflect the change in plan administration services fees due to the
    Reorganization.

(e) To reflect the change in other fees due to the Reorganization.

(f) To adjust the expense reimbursement to reflect no reduction in fees
    resulting from the Reorganization per the agreement (through Oct. 31, 2009)
    by RiverSource Investments, LLC and its affiliates to waive certain fees and
    absorb certain expenses of the combined fund.


                                       60

PART C. OTHER INFORMATION

Item 15. Indemnification

The Articles of Incorporation of the registrant provide that the Fund shall
indemnify any person who was or is a party or is threatened to be made a party,
by reason of the fact that she or he is or was a director, officer, employee or
agent of the Fund, or is or was serving at the request of the Fund as a
director, officer, employee or agent of another company, partnership, joint
venture, trust or other enterprise, to any threatened, pending or completed
action, suit or proceeding, wherever brought, and the Fund may purchase
liability insurance and advance legal expenses, all to the fullest extent
permitted by the laws of the State of Minnesota, as now existing or hereafter
amended. The By-laws of the registrant provide that present or former directors
or officers of the Fund made or threatened to be made a party to or involved
(including as a witness) in an actual or threatened action, suit or proceeding
shall be indemnified by the Fund to the full extent authorized by the Minnesota
Business Corporation Act, all as more fully set forth in the By-laws filed as an
exhibit to this registration statement.

Insofar as indemnification for liability arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

Any indemnification hereunder shall not be exclusive of any other rights of
indemnification to which the directors, officers, employees or agents might
otherwise be entitled. No indemnification shall be made in violation of the
Investment Company Act of 1940.

Any indemnification hereunder shall not be exclusive of any other rights of
indemnification to which the trustees, officers, employees or agents might
otherwise be entitled. No indemnification shall be made in violation of the
Investment Company Act of 1940.

Item 17. Undertakings.

(1)   The undersigned registrant agrees that prior to any public reoffering
      of the securities registered through the use of a prospectus which is a
      part of this registration statement by any person or party who is deemed
      to be an underwriter within the meaning of Rule 145(c) of the Securities
      Act, the reoffering prospectus will contain the information called for by
      the applicable registration form for the reofferings by persons who may be
      deemed underwriters, in addition to the information called for by the
      other items of the applicable form.

(2)   The undersigned registrant agrees that every prospectus that is filed
      under paragraph (1) above will be filed as a part of an amendment to the
      registration statement and will not be used until the amendment is
      effective, and that, in determining any liability under the 1933 Act, each
      post-effective amendment shall be deemed to be a new registration
      statement for the securities offered therein, and the offering of the
      securities at that time shall be deemed to be the initial bona fide
      offering of them.

(3)   The Registrant undertakes to file by Post-Effective Amendment an
      Opinion of Counsel supporting the tax consequences of the proposed
      reorganization within a reasonable time following the reorganization.
