* Effective on or about June 13, 2009, the Class R and Class I shares of the
  Seligman Fund 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 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 Fund (collectively, the "Funds") is a
registered open-end management investment company (or a series thereof). The
Selling Funds and the Buying Fund are part of the RiverSource Family of Funds,
which includes funds branded "RiverSource" as well as funds branded "Seligman."
Please read this combined proxy statement/prospectus and keep it for future
reference.

Although the Board of Directors of each Selling Fund (the "Board" or the "Board
of Directors") recommends that shareholders approve the reorganization of each
Selling Fund with the Buying Fund (each a "Reorganization"), the Reorganization
of each Selling Fund is not conditioned upon the Reorganization of the other
Selling Fund. Accordingly, if shareholders of one RiverSource Large Cap Equity
Fund approve its Reorganization, but shareholders of Seligman Common Stock Fund
do not approve that Selling Fund's Reorganization, it is expected that the
Reorganization of RiverSource Large Cap Equity Fund will take place as described
in this proxy statement/prospectus.


                                        1



HOW EACH REORGANIZATION WILL WORK

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

- - The Buying Fund will issue Reorganization Shares in an amount equal to the
  value of the assets that it receives from the Selling Fund, less the
  liabilities it assumes. The Reorganization Shares of each class will be
  distributed to the Selling Fund's shareholders of the corresponding class in
  proportion to their holdings in such class of the Selling Fund. For example,
  holders of Class A shares of a Selling Fund will receive Class A shares of the
  Buying Fund with the same aggregate net asset value as their 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 Buying Fund. The form of the Agreement is included as
Exhibit A.

The following is a summary. More complete information appears later in this
proxy statement/prospectus. You should read the entire 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 Buying Fund in
  exchange for shares of the Buying Fund ("Reorganization Shares") and the
  assumption by the Buying Fund of all of the Selling Fund's liabilities.

- - The 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. Reorganization Shares of each class of the 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 Buying Fund with the same aggregate net
  asset value as the aggregate net asset value of their 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 of your Selling Fund, 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 any 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 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 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

PROPOSALS 1(A) AND 1(B). REORGANIZATION OF EACH OF RIVERSOURCE LARGE CAP EQUITY
FUND AND SELIGMAN COMMON STOCK FUND, INC. INTO RIVERSOURCE DISCIPLINED EQUITY
FUND

The following tables describe the fees and expenses that you pay if you buy and
hold shares of a Selling Fund or shares of the Buying Fund. The tables also show
pro forma fees and expenses of the Buying Fund assuming the proposed
Reorganization relating to the 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 D. 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.

(a) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.08% for the most recent fiscal year. The index
    against which RiverSource Large Cap Equity Fund's performance is measured
    for purposes of determining the performance incentive adjustment is the
    Lipper Large-Cap Core Funds Index.


                                        6






(b) Other expenses include an administrative services fee, a transfer agency fee
    (for all classes except Class I), a custody fee, other nonadvisory expenses
    and a plan administration services fee (for Class R2, Class R3 and Class
    R4), 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.
(c) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until July 31, 2009, unless
    sooner terminated at the discretion of RiverSource Large Cap Equity 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 1.04% for Class A, 1.81% for Class B, 1.80% for Class C, 0.62%
    for Class I, 1.42% for Class R2, 1.17% for Class R3, 0.90% for Class R4 and
    0.67% for Class R5.
(d) In addition to the RiverSource Large Cap Equity Fund's total annual
    operating expenses that the Fund bears directly, the Fund's shareholders
    indirectly bear the expenses of the acquired funds (affiliated and
    unaffiliated funds) in which the Fund invests. The Fund's "Acquired fund
    fees and expenses," based on its investment in the acquired funds, is as
    shown.
(e) Effective on or about June 13, 2009, Class R will be redesignated Class R2,
    Class I will be redesignated Class R5, 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 funds fees and expenses, if any, 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.
(f) Includes the impact of a performance incentive adjustment fee that decreased
    the management fee by 0.04% for the most recent fiscal year. The index
    against which RiverSource Disciplined Equity Fund's performance is measured
    for purposes of determining the performance incentive adjustment is the
    Lipper Large-Cap Core Funds Index.
(g) Other expenses include an administrative services fee, a transfer agency fee
    (for all classes except Class I), a custody fee, other nonadvisory expenses,
    a plan administration services fee (for Class R2, Class R3 and Class R4),
    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 funds fees and expenses, if any, 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.
(h) The investment manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until July 31, 2009, unless
    sooner terminated at the discretion of RiverSource Disciplined Equity 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 1.05% for Class A, 1.81% for Class B, 1.81% for Class C, 0.72%
    for Class I, 1.52% for Class R2, 1.27% for Class R3, 0.88% for Class R4 and
    0.77% for Class R5.
*   The performance incentive adjustment for RiverSource Large Cap Equity Fund
    and RiverSource Disciplined Equity Fund are structured identically and are
    computed by comparing each Fund's performance to the performance of an index
    of comparable funds published by Lipper Inc., as noted above. The maximum
    adjustment (increase or decrease) is 0.12% of the average net assets on an
    annual basis. The adjustment is determined by measuring the percentage
    differences over a rolling 12-month period between the performance of the
    Fund and the change in the designated Lipper index. Additional information
    on the calculation methodology is set forth in the Reorganization SAI.

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 or Reorganizations 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:

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

The investment objectives for the Funds are as follows:

          SELLING FUND: RiverSource Large Cap Equity Fund (the "RiverSource
                        Selling Fund") seeks to provide shareholders with long-
                        term capital growth.

          SELLING FUND: The Seligman Selling Fund seeks total return through a
                        combination of capital appreciation and current income.

          BUYING FUND: RiverSource Disciplined Equity Fund (the "Buying Fund")
                       seeks to provide shareholders with long-term capital
                       growth.

COMPARISON OF PRINCIPAL INVESTMENT STRATEGIES

Each Fund invests predominantly in equity securities of large cap companies;
however, the RiverSource Selling Fund and the Buying Fund generally emphasize
investments in large cap companies to a greater extent than does the Seligman
Selling Fund. The Seligman Selling Fund seeks income consistent with the
Standard and Poor's 500 Composite Stock Price Index ("S&P 500 Index"), while the
Buying Fund and the RiverSource Selling Fund have no similar goal. The
RiverSource Selling Fund and the Buying Fund both invest at least 80% of their
respective net assets in companies with market capitalizations greater than $5
billion at the time of purchase. The Seligman Selling Fund may invest up to 10%
of its assets in foreign securities; however, this restriction excludes American
Depositary Receipts ("ADRs"), so the actual percentage the Seligman Selling Fund
invests both directly in foreign securities and indirectly in ADRs may exceed
10%. The RiverSource Selling Fund and the Buying Fund each may invest up to 25%
of assets in foreign investments, and count ADRs towards the 25% limit.

Detailed strategies for the Selling Funds and the Buying Fund are set forth
below. The RiverSource Selling Fund and the Buying Fund share identical
principal investment strategies.

produced by the Fund.

The Fund may purchase ADRs, which are publicly
traded instruments generally issued by
domestic banks or trust companies that
represent a security of a foreign issuer. The
Fund may invest up to 15% of its net assets in
illiquid securities (i.e., securities that
cannot be readily sold) and may invest up to
10% of its total assets directly in foreign
securities. The limit on foreign securities
does not include 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.

In addition to the principal investment strategies set forth above, each Fund
also has the following principal investment strategies:

The investment manager will choose equity investments by employing proprietary,
disciplined quantitative methods. The investment manager's disciplined
quantitative approach is designed to identify companies with:

- - Attractive valuations, based on factors such as price-to-earnings ratios;

- - Sound balance sheets; or

- - Improving outlooks, based on an analysis of return patterns over time.

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

- - The security is overvalued relative to other potential investments.

- - The company does not meet the investment manager's performance expectations.

The universe of stocks from which the investment manager selects the Funds'
investments primarily will be those included in the Funds' benchmark, the S&P
500 Index.

In selecting stocks for the Funds to purchase or to sell, the investment manager
employs a rigorous process to evaluate the relationship between the risk
associated with each security and its potential for positive returns. This
process includes factors such as:

- - Limits on positions relative to weightings in the benchmark index.

- - Limits on sector and industry allocations relative to the benchmark index.

- - Limits on size of holdings relative to market liquidity.

COMPARISON OF FUNDAMENTAL POLICIES

If the Reorganizations occur, 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 RiverSource Selling Fund and
the Buying Fund have identical fundamental investment policies. 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) and related
investment strategies. The RiverSource Selling Fund and the Buying Fund have the
same nonfundamental policies.

COMPARISON OF PRINCIPAL RISK FACTORS

Although the Funds describe them differently, the principal investment risks
associated with the Buying Fund and the Selling Funds are substantially similar
because the Funds have similar investment objectives, principal investment
strategies and investment policies except that the Seligman Selling Fund's
objective is capital appreciation and current income while the Buying Fund's
objective is long-term capital growth. By becoming shareholders of the Buying
Fund, shareholders of the Seligman Selling Fund will no longer be in a Fund that
has providing "current income" as part of the Fund's objective, and therefore
may have different exposure to market risk. 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. The 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
  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.

  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.

  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.

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

- - 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.


                                       14



- - 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.

- - 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.

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.

Tables. The first table shows total returns from hypothetical investments in
Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4 and Class R5
shares of RiverSource Large Cap Equity Fund. The second table shows total
returns from hypothetical investments in Class A, Class B, Class C, Class R (to
be known as Class R2) and Class I (to be known as Class R5) shares of Seligman
Common Stock Fund. The third table shows total returns from hypothetical
investments in Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4
and Class R5 shares of RiverSource Disciplined 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 Seligman Common Stock
  Fund Class R (to be known as Class R2) shares ;

- - no sales charge for Class R2, Class R3, Class R4, Class R5, RiverSource Large
  Cap Equity Fund and RiverSource Disciplined Equity Fund Class I and Seligman
  Common Stock Fund Class I (to be known as Class R5) shares; and

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


                                       15



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 S&P 500 Index, an unmanaged index of common stocks, is frequently used as a
general measure of market performance. The index reflects reinvestment of all
distributions and changes in market prices.

The Russell 1000 Index, an unmanaged index, measures the performance of the
1,000 largest companies in the Russell 3000(R) Index, which represents
approximately 90% of the total market capitalization of the Russell 3000 Index.
The index reflects reinvestment of all distributions and changes in market
prices.

The Lipper Large-Cap Core Funds Index includes the 30 largest large-cap core
funds tracked by Lipper Inc. The index's returns include net reinvested
dividends. The RiverSource Disciplined Equity Fund's and RiverSource Large Cap
Equity Fund's performance is currently measured against this index for purposes
of determining the performance incentive adjustment.

The Lipper Large-Cap Core Funds Average is an average of funds that, by
portfolio practice, invest at least 75% of their equity assets in companies with
market capitalizations (on a three-year weighted basis) above Lipper's U.S.
Diversified Equity (USDE) large-cap floor. Large-cap core funds typically have
an average price-to-earnings ratio, and three-year sales-per-share growth value,
compared to the S&P 500 Index.

For RiverSource Large Cap Equity Fund, effective Nov. 1, 2008, the Russell 1000
Index is replaced with the S&P 500 Index as the Fund's primary benchmark. The
investment manager made this recommendation to the RiverSource Large Cap Equity
Fund's Board because the new index more closely aligns to the Fund's investment
strategy.

Investors cannot invest directly in an index or an average.

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 Buying Fund.

- - Each Selling Fund will transfer all of its assets to the Buying Fund and, in
  exchange, the 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, Class R3, Class R4, Class R5 and/or Class I 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 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, Class R3, Class R4, Class R5
  and/or Class I shareholders of the 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 Buying Fund will be computed
  as of 3:00 p.m., Central time, 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 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 closing date thereof. In the event of a termination, RiverSource
Investments 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 the 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, Class R3, Class R4, Class R5 and/or Class
  I 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, Class R3, Class R4, Class R5 and/or Class
  I 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.


                                       20



- - 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,
  Class R3, Class R4, Class R5 and/or Class I 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, Class R2, Class R3, Class R4, Class R5 and/or Class I shares as
  applicable, of the Selling Fund solely for Class A, Class B, Class C, Class
  R2, Class R3, Class R4, Class R5 shares and/or Class I 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, Class R3, Class R4, Class R5 and/or Class I 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, Class R2, Class R3, Class R4, Class R5 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, Class R3, Class R4, Class R5 and/or Class I 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 C2, 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,
  Class R3, Class R4, Class R5 and/or Class I 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 both of the Selling Funds, portfolio manager substitutions
independent of the Reorganizations have occurred and resulted in substantial
portfolio turnover. An additional portion of or all of the portfolio assets of
each Selling Fund may also 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

                                       21



any, and net realized capital gains, if any, through the closing of the
Reorganization. These distributions will be taxable to shareholders.

A Fund's ability to carry forward capital losses and to use them to offset
future gains may be limited as a result of the Reorganization. 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 the Reorganizations will have tax
attributes that reflect a blending of the tax attributes of the 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 another 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. 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 paragraph provides a brief summary of the tax
impact of the Reorganizations had they both 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 the Selling Funds resulting from RiverSource Investment's purchase of
Seligman and portfolio manager substitutions made independent of the
Reorganizations, and the substantial volatility in the marketplace, the actual
tax impact of the Reorganizations could differ substantially from those
described below.

Proposals 1(a) and (b): Reorganizations of each of RiverSource Large Cap Equity
Fund and Seligman Common Stock Fund into RiverSource Disciplined Equity Fund: As
of October 31, 2008, RiverSource Large Cap Equity Fund (a Selling Fund) had no
capital loss carryforwards but had net realized losses equal to approximately
16.1% of net assets and unrealized losses equal to approximately 65.8% of net
assets. Seligman Common Stock Fund (a Selling Fund) had net realized losses
including capital loss carryforwards equal to approximately 18.3% of net assets
and unrealized losses equal to approximately 38.2% of net assets. RiverSource
Disciplined Equity Fund (Buying Fund) had no capital loss carryforwards but had
net realized losses equal to approximately 2.9% of net assets and unrealized
losses equal to approximately 49.8% of net assets. If both of the
Reorganizations had occurred on October 31, 2008, the loss limitation rules
would not have affected the combined Fund's ability to use any of the Funds'
realized losses to offset gains recognized by the combined Fund. The losses of
each Selling Fund 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, both Selling Funds experienced significant
portfolio turnover. The recognition of gain or loss resulting from such
portfolio turnover could increase the potential tax costs of the Reorganizations
to shareholders of the Selling Funds relative to the costs described above.
Additionally, to the extent Seligman Common Stock Fund further realizes its
unrealized and losses, and to the extent Buying Fund 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 shareholders of the Selling
Funds.

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.


                                       22



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 noted 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 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:

 The Board considered that the Funds share similar investment objective of
 seeking capital appreciation, but considered that Seligman Common Stock Fund
 also seeks current income. The Board considered that each of the Funds invests
 at least 80% of its net assets in equity securities, but noted that RiverSource
 Large Cap Equity Fund and RiverSource Disciplined Equity Fund invest in equity
 securities of companies listed with market capitalizations greater than $5
 billion at the time of purchase, while Seligman Common Stock Fund invests in
 equity securities with market capitalizations greater than $3 billion at the
 time of purchase. The Board considered that Seligman Common Stock Fund may
 invest up to 10% of assets in foreign securities (excluding American Depositary
 Receipts (ADRs), and that RiverSource Large Cap Equity Fund and RiverSource
 Disciplined Equity Fund may invest up to 25% of assets in foreign investments
 (including ADRs).

- - 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 for Seligman Common Stock 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 and RiverSource Large Cap Equity Fund's Class A,
  Class B, Class C, Class I, Class R2, Class R3, Class R4 and Class R5 shares
  (adjusted to reflect current fees, before giving effect to any applicable
  performance incentive adjustment and excluding certain other fees and
  expenses) were the same or higher than the gross expense ratio for RiverSource
  Disciplined Equity Fund's Class A, Class B, Class C, Class I, Class R2, Class
  R3, Class R4 and Class R5 shares (adjusted to reflect current fees and before
  giving effect to any applicable performance incentive adjustment). The Board
  considered that RiverSource Large Cap Equity Fund and RiverSource Disciplined
  Equity Fund (Class R4 shares only) are currently subject to a commitment by
  the investment manager and its affiliates to waive fees or cap expenses, and
  that the net expense ratio of RiverSource Large Cap Equity Fund's Class A,
  Class B, Class C, and Class R4 shares (adjusted to reflect current fees,
  before giving effect to any applicable performance incentive adjustment and
  excluding certain other fees and expenses) were higher than the applicable
  gross or net expense ratio of RiverSource Disciplined Equity Fund's Class A,
  Class B, Class C, and Class R4 shares (adjusted to reflect current fees and
  before giving effect to any applicable performance incentive adjustment), and
  that the net expense ratio of RiverSource Large Cap Equity Fund's Class I,
  Class R2, Class R3 and Class R5 shares (adjusted to reflect current fees,
  before giving effect to any applicable performance incentive adjustment and
  excluding certain other fees and expenses) were slightly higher than the gross
  expense ratio of RiverSource Disciplined Equity Fund's Class I, Class R2,
  Class R3 and Class R5 shares (adjusted to reflect current fees and before
  giving effect to any applicable performance incentive adjustment). 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, expense impacts, with respect to a Fund's Class A shares are
  discussed below:

 The Board considered that as a result of the Reorganization, the expenses of
 RiverSource Large Cap Equity Fund would decline by approximately 0.09% on a
 gross expense basis and by 0.02% on a net expense basis (adjusted to reflect
 current fees, 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), and that the expenses of Seligman Common Stock Fund would
 decline by approximately 0.24% on a net expense basis (adjusted to reflect
 current fees, 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).


                                       23



- - 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 to take advantage of other economies of scale
  associated with a larger fund. For example, a larger fund may realize
  breakpoints more quickly, it should 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
  Selling Funds 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 neither of the Reorganizations
  will dilute the interests of the current shareholders because each 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 Buying Fund equal in
  value to his or her Class A shares in the Selling Fund at the time of the
  Reorganization.

- - 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 Selling 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, the Board considered that the performance of RiverSource
 Disciplined Equity Fund was generally stronger than the performance of each of
 RiverSource Large Cap Equity Fund and Seligman Common Stock Fund (both on a
 relative basis and when compared with their respective peer groups). The Board
 noted the weak asset level of Seligman Common Stock Fund. The Board also noted
 the relatively weak prospects for asset growth for RiverSource Large Cap Equity
 Fund and Seligman Common Stock Fund, particularly compared to RiverSource
 Disciplined Equity Fund. The Board accorded particular weight to the fact that
 RiverSource Disciplined Equity Fund has substantially greater assets than
 Seligman Common Stock Fund, noting that RiverSource Disciplined Equity Fund was
 more than nineteen times the size of Seligman Common Stock Fund.

- - POTENTIAL BENEFITS TO THE INVESTMENT MANAGER AND ITS AFFILIATES. The Board
  considered the potential benefits from the Reorganization that could be
  realized by the investment manager and its affiliates. The Board also
  considered, however, that shareholders of the Selling Fund are expected to
  benefit over time from any decrease in overall operating expense ratios
  resulting from the proposed Reorganization.

BOARD DETERMINATIONS

After considering the factors described above and other relevant information, at
a meeting held on Jan. 8, 2009, each Selling Fund Board, including a majority of
the independent Board members, found 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 the 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
Reorganizations. 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.


                                       24



For RiverSource Large Cap Equity Fund, the Agreement must be approved by a
majority of the voting power of all shares entitled to vote.

For Seligman Common Stock Fund, the Agreement must be approved by the
affirmative vote of a majority of the outstanding voting securities of the
Selling Fund. A vote of a majority of the outstanding voting securities of the
Selling Fund is defined in 1940 Act as a 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 more than 50% of the outstanding shares 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.


                                       25



SECTION B -- PROXY VOTING AND SHAREHOLDER MEETING INFORMATION

Reference to the "Fund" in this section is a reference to each Selling Fund.

VOTING. Shareholders of record of the RiverSource Selling Fund on April 3, 2009
are entitled to vote based on their total dollar interest in the Fund
irrespective of which class they own. Shareholders of record of the Seligman
Selling Fund 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
Selling Fund will vote together as a class on its proposed Reorganization.

A quorum is required to take action at the Meeting. With respect to the
RiverSource Selling Fund, the presence at the Meeting, in person or by proxy, of
shareholders entitled to cast at least ten percent (10%) of the shares
outstanding and entitled to vote at the Meeting shall constitute a quorum. With
respect to the Seligman Selling Fund, the presence at the Meeting, in person or
by proxy, of at least one-third of all shares outstanding and entitled to vote
at the Meeting 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 authority to
vote.)

If your shares are held in an IRA account with Ameriprise Trust Company as
custodian, you have the right to instruct the IRA Custodian how to vote those
shares. The IRA Custodian will vote any shares for which it has not received
voting instructions in proportionately the same manner -- either For, Against,
or Abstain -- as other Fund shareholders have voted.

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
Reorganization 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
of your Selling Fund, you may revoke by providing written notice to that Selling
Fund (Attention: Secretary) at 50606 Ameriprise Financial Center, Minneapolis,
MN 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 Selling Fund will be held
simultaneously with the meeting for the other Selling Fund, with each
Reorganization being voted on separately by the shareholders of the relevant
Selling Fund. If any shareholder objects to the holding of simultaneous
meetings, the shareholder may move for an adjournment of his or her Selling
Fund's meeting to a time after the Meeting so that a meeting for that Selling
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 Funds (see discussion of "Costs" under
"Reasons for the Proposed Reorganization 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 $217,611.


                                       26



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.

DISSENTERS' RIGHT OF APPRAISAL. Under Sections 302A.471 and 302A.473 of the
Minnesota Business Corporation Act, the RiverSource Selling Fund shareholders
are entitled to assert dissenters' rights in connection with their Selling
Fund's Reorganization and obtain payment of the "fair value" of their shares,
provided that they comply with the requirements of Minnesota law. A copy of the
relevant provisions is attached as Exhibit B.

Notwithstanding the provision of Minnesota 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, dissenters'
rights will be determined in accordance with the SEC's interpretation. As a
result, if any shareholder elects to exercise dissenters' rights under Minnesota
law, the RiverSource 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.

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

ADJOURNMENT. With respect to the RiverSource Selling Fund Reorganization, in the
event that not enough votes are received by the time scheduled for the Meeting,
the persons named as proxies may move for one or more adjournments of the
meeting for a period of not more than 120 days of the original record date for
the Meeting in the aggregate to allow further solicitation of shareholders on
the proposals. Any adjournment requires the affirmative vote of a majority of
the voting power of the shares present at the Meeting. With respect to the
Seligman Selling Fund Reorganization, if 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 Reorganization 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 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 in connection with the proposed
Reorganizations.

If insufficient votes are received by the time of the Meeting, the persons named
as proxies will vote in favor of adjournment those shares they are entitled to
vote that have voted in favor of the proposal. They will vote against any
adjournment those shares that have voted against the proposal. A shareholder
vote may be taken on one or more of the items in this proxy statement prior to
adjournment if sufficient votes have been received with respect to that
particular proposal(s), and may adjourn with respect to those proposals for
which sufficient votes have not yet been received.

C-3       Financial Highlights of the Buying Fund
</Table>


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 the Seligman Selling Fund.

CAPITALIZATION OF SELLING FUNDS AND BUYING FUND

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, LLC. 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 net assets are determined by adding the net assets, less
any Reorganization costs, of the Selling Fund and the net assets of the Buying
Fund. 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 Common Stock Fund into
RiverSource Disciplined Equity Fund, the Reorganization costs reduced pro forma
combined net assets by $85,455 for Class A, $2,481 for Class B, $1,017 for Class
C, $197 for Class R2, and $525 for Class R5. For the Reorganization of Seligman
Common Stock Fund and RiverSource Large Cap Equity Fund into RiverSource
Disciplined Equity Fund, the Reorganization costs reduced pro forma combined net
assets by $80,055 for Class A, $8,143 for Class B, $640 for Class C, $53 for
Class R2, and $784 for Class R5.

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"), buying entity
identified in Schedule A hereto ("Buying Corporation")(2), on behalf of its
series thereof identified in Schedule A hereto as the 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 the Buying Fund contemplated hereby had been the
subject of a separate agreement. As context requires a Selling Corporation that
is not organized as a series fund and that may not be considered or meet the
definition of "Selling Fund" as set forth above, may be referred to as a
"Selling Fund," 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"). The 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 Buying Fund. The
      Buying Fund will assume all liabilities of the corresponding Selling Fund.
      At the Closing, the Buying Corporation will deliver shares of the 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 Buying Fund, computed as described in paragraph
      3(b). Each Selling Fund will not pay a sales charge on the receipt of the
      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 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 Buying Fund's then current prospectus.

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

   c. At the Closing, each Selling Fund will provide the 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 the 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 the Buying
      Fund on the Valuation Date. Both computations will be certified by an
      officer of RiverSource Investments, LLC, the investment manager.

4.  LIQUIDATION AND DISSOLUTION OF THE SELLING FUND.

   a. On the date of the Closing, each Selling Corporation will liquidate each
      Selling Fund and distribute shares of each class of the Buying Fund to the
      shareholders of record of such Selling Fund's corresponding class. The
      Buying Fund will establish shareholder accounts 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 on the books of each Selling

      Code, (ii) all of the Selling Fund's investment company taxable income as
      defined in Section 852 of the Code (in each case computed without regard
      to any deduction for dividends paid) and (iii) all of the Selling Fund's
      net capital gain realized (after reduction for any capital loss
      carryover), in each case for the current taxable year (which will end on
      the Closing date) and any preceding taxable years for which such a
      dividend is eligible to be made under Section 855 of the Code.

8.  CONDITIONS TO OBLIGATIONS OF THE SELLING CORPORATION. The obligations of the
    Selling Corporation with respect to each Reorganization are subject to the
    satisfaction of the following conditions:

   a. Shareholder Approval. For RiverSource Large Cap Equity Fund this Agreement

      by the affirmative vote of a majority of the outstanding voting securities
      of the Selling Fund. A vote of a majority of the outstanding voting
      securities of the Selling Fund is defined in 1940 Act as a 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 more than 50% of the

      a certificate to each Selling Fund confirming that, as of the Closing, the
      representations and warranties set forth in Section 5 are true and correct
      and that there have been no material adverse changes in the financial
      condition, results of operations, business, properties or assets of the
      Buying Fund since the date of its last financial statement, except as
      otherwise indicated in any financial statements, certified by an officer
      of the Buying Corporation, and delivered to such Selling Fund on or prior
      to the last business day before the Closing.

   c. Regulatory Approvals.

       effective and no stop orders under the 1933 Act will have been issued.

       regulatory authorities will have been obtained.

   d. Opinion of Counsel. The Selling Corporation will have received the opinion
      of counsel for the Buying Corporation, dated as of the date of the
      Closing, to the effect that: (i) the Buying Corporation is a corporation
      duly organized and validly existing under the laws of the state of
      Minnesota; (ii) each Buying Fund is a series of the Buying Corporation, an
      open-end management investment company registered under the 1940 Act;
      (iii) this Agreement and the Reorganization has been authorized and
      approved by all requisite action of the Buying Corporation and the Buying
      Fund and this Agreement has been duly executed by, and is a valid and
      binding obligation of, the Buying Corporation; and (iv) the shares to be
      issued in the Reorganization are duly authorized and upon issuance in
      accordance with this Agreement will be validly issued, fully paid and non-
      assessable shares of the Buying Fund.

9.  CONDITIONS TO OBLIGATIONS OF THE SELLING CORPORATION AND THE BUYING
    CORPORATION. The obligations of each of the Selling Corporation and the
    Buying Corporation with respect to each Reorganization are subject to the
    satisfaction of the following conditions:

   Tax Opinion. With respect to the Reorganization between a Selling Fund and
   the Buying Fund, the Selling Fund shall have received an opinion of Ropes &
   Gray LLP satisfactory to such Selling Fund, and the Buying Fund shall have
   received an opinion of Ropes & Gray LLP satisfactory to the Buying Fund, each
   substantially to the effect that, on the basis of existing provisions of the
   Code, Treasury regulations promulgated thereunder, current administrative
   rules,

                                       A.5



   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;

   c. No gain or loss will be recognized by the Buying Fund upon receipt of the
      assets of the Selling Fund in exchange for acquisition shares and the
      assumption by the Buying Fund of all liabilities of the Selling Fund as
      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;

   g. The aggregate tax basis of the acquisition shares the Selling Fund
      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

   i. 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 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.

10. AMENDMENT; TERMINATION; NON-SURVIVAL OF COVENANTS, WARRANTIES AND
REPRESENTATIONS.

   a. This Agreement may be amended in writing if authorized by the respective
      Boards of Directors. The Agreement may be so amended at any time before or
      after the shareholder approval contemplated by paragraph 1 is obtained.

   b. At any time prior to the Closing, any of the parties may waive in writing
      (i) any inaccuracies in the representations and warranties made to it and
      (ii) compliance with any of the covenants or conditions made for its
      benefit.

   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
      performance or a material covenant of the other party is not fulfilled on
      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.

   d. This Agreement may be terminated by any party at any time prior to the
      Closing, whether before or after approval by the shareholders of each
      Selling Fund, without any liability on the part of any party or its
      respective directors, officers, or shareholders, on written notice to the
      other party, and shall be terminated without liability as of the close of
      business on _____________, or a later date agreed upon by the officers of
      the Selling Corporation and the Buying Corporation, if the Closing is not
      effected on or prior to that date.


                                       A.6



   e. The representations, warranties and covenants contained in this Agreement,
      or in any document delivered in connection with this Agreement, will
      survive the Reorganization.

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 Buying Fund. Certain
    non-recurring Reorganization costs and related Reorganization expenses may
    be borne by a Selling Fund to the extent the Reorganization is expected to
    result in a reduction to the expense ratio for such Selling Fund.
    Reorganization costs and related Reorganization expenses include (i) legal
    and auditor or accounting fees ("Professional Fees") associated with the
    preparation and filing of the proxy statement/prospectus and (ii) expenses
    associated with the printing and mailing of any shareholder communications,
    including the proxy statement/prospectus that forms a part 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

MINNESOTA BUSINESS CORPORATION ACT SECTIONS 302A.471 AND 302A.473

Minnesota law requires that we provide you with a copy of the state law on
dissenters' 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 RiverSource Large Cap Equity 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 dissenters' rights under Minnesota
law, the 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.

302A.471. RIGHTS OF DISSENTING SHAREHOLDERS

SUBDIVISION 1. ACTIONS CREATING RIGHTS. A shareholder of a corporation may
dissent from, and obtain payment for the fair value of the shareholder's shares
in the event of, any of the following corporate actions:

(a) unless otherwise provided in the articles, an amendment of the articles that
    materially and adversely affects the rights or preferences of the shares of
    the dissenting shareholder in that it:

  (1) alters or abolishes a preferential right of the shares;

  (2) creates, alters, or abolishes a right in respect of the redemption of the
      shares, including a provision respecting a sinking fund for the redemption
      or repurchase of the shares;

  (3) alters or abolishes a preemptive right of the holder of the shares to
      acquire shares, securities other than shares, or rights to purchase shares
      or securities other than shares;

  (4) excludes or limits the right of a shareholder to vote on a matter, or to
      cumulate votes, except as the right may be excluded or limited through the
      authorization or issuance of securities of an existing or new class or
      series with similar or different voting rights; except that an amendment
      to the articles of an issuing public corporation that provides that
      section 302A.671 does not apply to a control share acquisition does not
      give rise to the right to obtain payment under this section;

  (5) eliminates the right to obtain payment under this subdivision;

(b) a sale, lease, transfer, or other disposition of property and assets of the
    corporation that requires shareholder approval under section 302A.661,
    subdivision 2, but not including a disposition in dissolution described in
    section 302A.725, subdivision 2, or a disposition pursuant to an order of a
    court, or a disposition for cash on terms requiring that all or
    substantially all of the net proceeds of disposition be distributed to the
    shareholders in accordance with their respective interests within one year
    after the date of disposition;

(c) a plan of merger, whether under this chapter or under chapter 322B, to which
    the corporation is a party, except as provided in subdivision 3, and except
    for a plan of merger adopted under section 302A.626;

(d) a plan of exchange, whether under this chapter or under chapter 322B, to
    which the corporation is a party as the corporation whose shares will be
    acquired by the acquiring corporation, except as provided in subdivision 3;

(e) a plan of conversion adopted by the corporation; or

(f) Any other corporate action taken pursuant to a shareholder vote with respect
    to which the articles, the bylaws, or a resolution approved by the board
    directs that dissenting shareholders may obtain payment for their shares.

SUBDIVISION 2. BENEFICIAL OWNERS.

(a) A shareholder shall not assert dissenters' rights as to less than all of the
    shares registered in the name of the shareholder, unless the shareholder
    dissents with respect to all the shares that are beneficially owned by
    another person but registered in the name of the shareholder and discloses
    the name and address of each beneficial owner on whose behalf the
    shareholder dissents. In that event, the rights of the dissenter shall be
    determined as if the shares as to which the shareholder has dissented and
    the other shares were registered in the names of different shareholders.

(b) A beneficial owner of shares who is not the shareholder may assert
    dissenters' rights with respect to shares held on behalf of the beneficial
    owner, and shall be treated as a dissenting shareholder under the terms of
    this section and section 302A.473, if the beneficial owner submits to the
    corporation at the time of or before the assertion of the rights a written
    consent of the shareholder.

SUBDIVISION 3. RIGHTS NOT TO APPLY.

(a) Unless the articles, the bylaws, or a resolution approved by the board
    otherwise provide, the right to obtain payment under this section does not
    apply to a shareholder of (1) the surviving corporation in a merger with
    respect to shares of the

                                       B.1



    shareholder that are not entitled to be voted on the merger and are not
    canceled or exchanged in the merger or (2) the corporation whose shares will
    be acquired by the acquiring organization in a plan of exchange with respect
    to shares of the shareholder that are not entitled to be voted on the plan
    of exchange and are not exchanged in the plan of exchange.

(b) If a date is fixed according to section 302A.445, subdivision 1, for the
    determination of shareholders entitled to receive notice of and to vote on
    an action described in subdivision 1, only shareholders as of the date
    fixed, and beneficial owners as of the date fixed who hold through
    shareholders, as provided in subdivision 2, may exercise dissenters' rights.

(c) Notwithstanding subdivision 1, the right to obtain payment under this
    section, other than in connection with a plan of merger adopted under
    section 302A.621, is limited in accordance with the following provisions:

  (1) The right to obtain payment under this section is not available for the
      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 the Nasdaq Stock Market.

  (2) The applicability of clause (1) is determined as of:

     (i) the record date fixed to determine the shareholders entitled to receive
         notice of, and to vote at, the meeting of shareholders to act upon the
         corporate action described in subdivision 1; or

     (ii) the day before the effective date of corporate action described in
          subdivision 1 if there is no meeting of shareholders.

  (3) Clause (1) is not applicable, and the right to obtain payment under this
      section is available pursuant to subdivision 1, for the holders of any
      class or series of shares who are required by the terms of the corporate
      action described in subdivision 1 to accept for such shares anything other
      than shares, or cash in lieu of fractional shares, of any class or any
      series of shares of a domestic or foreign corporation, or any other
      ownership interest of any other organization, that satisfies the standards
      set forth in clause (1) at the time the corporate action becomes
      effective.

SUBDIVISION 4. OTHER RIGHTS. The shareholders of a corporation who have a right
under this section to obtain payment for their shares, or who would have the
right to obtain payment for their shares absent the exception set forth in
paragraph (c) of subdivision 3, do not have a right at law or in equity to have
a corporate action described in subdivision 1 set aside or rescinded, except
when the corporate action is fraudulent with regard to the complaining
shareholder or the corporation.

302A.473. PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS

SUBDIVISION 1. DEFINITIONS.

(a) For purposes of this section, the terms defined in this subdivision have the
    meanings given them.

(b) "Corporation" means the issuer of the shares held by a dissenter before the
    corporate action referred to in section 302A.471, subdivision 1 or the
    successor by merger of that issuer.

(c) "Fair value of the shares" means the value of the shares of a corporation
    immediately before the effective date of the corporate action referred to in
    section 302A.471, subdivision 1.

(d) "Interest" means interest commencing five days after the effective date of
    the corporate action referred to in section 302A.471, subdivision 1, up to
    and including the date of payment, calculated at the rate provided in
    section 549.09 for interest on verdicts and judgments.

SUBDIVISION 2. NOTICE OF ACTION. If a corporation calls a shareholder meeting at
which any action described in section 302A.471, subdivision 1 is to be voted
upon, the notice of the meeting shall inform each shareholder of the right to
dissent and shall include a copy of section 302A.471 and this section and a
brief description of the procedure to be followed under these sections.

SUBDIVISION 3. NOTICE OF DISSENT. If the proposed action must be approved by the
shareholders and the corporation holds a shareholder meeting, a shareholder who
is entitled to dissent under section 302A.471 and who wishes to exercise
dissenters' rights must file with the corporation before the vote on the
proposed action a written notice of intent to demand the fair value of the
shares owned by the shareholder and must not vote the shares in favor of the
proposed action.

SUBDIVISION 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES.

(a) After the proposed action has been approved by the board and, if necessary,
    the shareholders, the corporation shall send to (i) all shareholders who
    have complied with subdivision 3, (ii) all shareholders who did not sign or
    consent to a written action that gave effect to the action creating the
    right to obtain payment under section 302A.471, and (iii) all shareholders
    entitled to dissent if no shareholder vote was required, a notice that
    contains:

  (1) The address to which a demand for payment and certificates of certificated
      shares must be sent in order to obtain payment and the date by which they
      must be received;


                                       B.2



  (2) Any restrictions on transfer of uncertificated shares that will apply
      after the demand for payment is received;

  (3) A form to be used to certify the date on which the shareholder, or the
      beneficial owner on whose behalf the shareholder dissents, acquired the
      shares or an interest in them and to demand payment; and

  (4) A copy of section 302A.471 and this section and a brief description of the
      procedures to be followed under these sections.

(b) In order to receive the fair value of the shares, a dissenting shareholder
    must demand payment and deposit certificated shares or comply with any
    restrictions on transfer of uncertificated shares within 30 days after the
    notice required by paragraph (a) was given, but the dissenter retains all
    other rights of a shareholder until the proposed action takes effect.

SUBDIVISION 5. PAYMENT; RETURN OF SHARES.

(a) After the corporate action takes effect, or after the corporation receives a
    valid demand for payment, whichever is later, the corporation shall remit to
    each dissenting shareholder who has complied with subdivisions 3 and 4 the
    amount the corporation estimates to be the fair value of the shares, plus
    interest, accompanied by:

  (1) The corporation's closing balance sheet and statement of income for a
      fiscal year ending not more than 16 months before the effective date of
      the corporate action, together with the latest available interim financial
      statements;

  (2) An estimate by the corporation of the fair value of the shares and a brief
      description of the method used to reach the estimate; and

  (3) A copy of section 302A.471 and this section, and a brief description of
      the procedure to be followed in demanding supplemental payment.

(b) The corporation may withhold the remittance described in paragraph (a) from
    a person who was not a shareholder on the date the action dissented from was
    first announced to the public or who is dissenting on behalf of a person who
    was not a beneficial owner on that date. If the dissenter has complied with
    subdivisions 3 and 4, the corporation shall forward to the dissenter the
    materials described in paragraph (a), a statement of the reason for
    withholding the remittance, and an offer to pay to the dissenter the amount
    listed in the materials if the dissenter agrees to accept that amount in
    full satisfaction. The dissenter may decline the offer and demand payment
    under subdivision 6. Failure to do so entitles the dissenter only to the
    amount offered. If the dissenter makes demand, subdivision 7 and 8 apply.

(c) If the corporation fails to remit payment within 60 days of the deposit of
    certificates or the imposition of transfer restrictions on uncertificated
    shares, it shall return all deposited certificates and cancel all transfer
    restrictions. However, the corporation may again give notice under
    subdivision 4 and require deposit or restrict transfer at a later time.

SUBDIVISION 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the
amount remitted under subdivision 5 is less than the fair value of the shares
plus interest, the dissenter may give written notice to the corporation of the
dissenter's own estimate of the fair value of the shares, plus interest, within
30 days after the corporation mails the remittance under subdivision 5, and
demand payment of the difference. Otherwise, a dissenter is entitled only to the
amount remitted by the corporation.

SUBDIVISION 7. PETITION; DETERMINATION. If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand, either
pay to the dissenter the amount demanded or agreed to by the dissenter after
discussion with the corporation or file in a court a petition requesting that
the court determine the fair value of the shares, plus interest. The petition
shall be filed in the county in which the registered office of the corporation
is located, except that a surviving foreign corporation that receives a demand
relating to the shares of a constituent domestic corporation shall file the
petition in the county in this state in which the last registered office of the
constituent corporation was located. The petition shall name as parties all
dissenters who have demanded payment under subdivision 6 and who have not
reached agreement with the corporation. The corporation shall, after filing the
petition, serve all parties with a summons and copy of the petition under the
rules of civil procedure. Nonresidents of this state may be served by registered
or certified mail or by publication as provided by law. Except as otherwise
provided, the rules of civil procedures apply to this proceeding. The
jurisdiction of the court is plenary and exclusive. The court may appoint
appraisers, with powers and authorities the court deems proper, to receive
evidence on and recommend the amount of the fair value of the shares. The court
shall determine whether the shareholder or shareholders in question have fully
complied with the requirements of this section, and shall determine the fair
value of the shares, taking into account any and all factors the court finds
relevant, computed by any method or combination of methods that the court, in
its discretion, sees fit to use, whether or not used by the corporation or by a
dissenter. The fair value of the shares as determined by the court is binding on
all shareholders, wherever located. A dissenter is entitled to judgment in cash
for the amount by which the fair value of the shares as determined by the court,
plus interest, exceeds the amount, if any, remitted under subdivision 5, but
shall not be liable to the corporation for the amount, if any, by which the
amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair
value of the shares as determined by the court, plus interest.


                                       B.3



SUBDIVISION 8. COSTS; FEES; EXPENSES.

(a) The court shall determine the costs and expenses of a proceeding under
    subdivision 7, including the reasonable expenses and compensation of any
    appraisers appointed by the court, and shall assess those costs and expenses
    against the corporation, except that the court may assess part or all of
    those costs and expenses against a dissenter whose action in demanding
    payment under subdivision 6 is found to be arbitrary, vexatious, or not in
    good faith.

(b) If the court finds that the corporation has failed to comply substantially
    with this section, the court may assess all fees and expenses of any experts
    or attorneys as the court deems equitable. These fees and expenses may also
    be assessed against a person who has acted arbitrarily, vexatiously, or not
    in good faith in bringing the proceeding, and may be awarded to a party
    injured by those actions.

(c) The court may award, in its discretion, fees and expenses to an attorney for
    the dissenters out of the amount awarded to the dissenters, if any.

EXHIBIT C

SUPPLEMENTAL INFORMATION

The information in the service section in this Exhibit C 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 FUND

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

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 non-
affiliated 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 Reorganization SAI and its annual and
semiannual reports.

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 or unaffiliated money market fund. See "Cash Reserves" under the
section "General Information" for more information.

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. 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.

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. 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, 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.

FUND MANAGEMENT AND COMPENSATION

INVESTMENT MANAGER

RiverSource Investments, LLC, 200 Ameriprise Financial Center, Minneapolis,
Minnesota 55474, is the investment manager to the RiverSource funds (including
the RiverSource Partners funds, Threadneedle funds and Seligman funds), and is a
wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial).
Ameriprise Financial is a financial planning and financial services company that
has been offering solutions for clients' asset accumulation, income management
and protection

                                       C.1



needs for more than 110 years. In addition to managing investments for all of
the RiverSource funds, RiverSource Investments manages investments for itself
and its affiliates. For institutional clients, RiverSource Investments and its
affiliates provide investment management and related services, such as separate
account asset management, and institutional trust and custody, as well as other
investment products. For all of its clients, RiverSource Investments seeks to
allocate investment opportunities in an equitable manner over time. See the
Reorganization SAI for more information.

The Fund pays RiverSource Investments a fee for managing its assets. Under the
Investment Management Services Agreement ("IMS Agreement"), the fee for the most
recent fiscal year was 0.53% of the Fund's average daily net assets, including
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 Fund's performance is currently measured for purposes of the performance
incentive adjustment is the Lipper Large-Cap Core 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. Under the IMS Agreement, the Fund also pays taxes, brokerage
commissions, and nonadvisory expenses. A discussion regarding the basis for the
Board approving the Agreement is available in the Fund's most recent annual or
semiannual shareholder report.

                                       C.2



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.


                                       C.4



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,

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.

(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.


                                       C.6



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

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

                                       C.7



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

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

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.

  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.


                                       C.8



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

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

- - purchased through reinvestment of dividends and capital gain distributions.

- - in the event of the shareholder's death.

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

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

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

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

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

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

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

CLASS B AND CLASS C -- CDSC ALTERNATIVE

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

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

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

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

<Table>

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

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.


                                       C.9



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

FOR CLASS C, a 1% CDSC may be charged if you sell your shares within one year
after purchase. Although there is no front-end sales charge when you buy Class C
shares, the distributor pays a total amount up to 1% (including sales commission
and advance of service fees) to financial intermediaries that sell Class C
shares. See "Buying and Selling Shares -- Distribution and Service Fees." A
portion of this commission may, in turn, be paid to your financial advisor. The
distributor receives any CDSC imposed when you sell your Class C shares. You may
not make additional purchases of Class C shares if your ROA exceeds $999,999.99.

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

EXAMPLE

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

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

- - in the event of the shareholder's death.

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

- - sold under an approved substantially equal periodic payment arrangement.

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

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

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

- - in the event of the shareholder's death.

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

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

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

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

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

CLASS I, CLASS R2, CLASS R3, CLASS R4, CLASS R5 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

                                      C.10



intermediary through which you are investing in the fund is unable to verify
your identity, your account may be closed, or other steps may be taken, as
deemed appropriate.

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

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

 METHODS OF PURCHASING SHARES

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

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

                                      C.14



  clients, which typically engage in daily transactions, are not subject to this
  limit, although the fund may seek the assistance of financial intermediaries
  in applying similar restrictions on their participants or clients. The fund's
  ability to monitor and discourage abusive trading practices in omnibus
  accounts is more limited.

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

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

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

Other exchange policies:

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

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

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

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

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

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

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

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

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

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

                                      C.16



shares will be deemed to have the original cost and purchase date for purposes
of applying the CDSC (if any) to subsequent redemptions. Systematic withdrawals
and purchases will be excluded from this policy.

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

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

                                      C.17



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

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

REINVESTMENTS

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

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

TAXES

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

For tax purposes, an exchange is considered a sale and purchase, and may result
in a gain or loss. A sale is a taxable transaction. Generally, if you sell
shares for less than their cost, the difference is a capital loss or if you sell
shares for more than their cost, the difference is a capital gain. Your gain may
be short term (for shares held for one year or less) or long term (for shares
held for more than one year).

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

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.


                                      C.18



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 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."


                                      C.19



PAYMENTS TO FINANCIAL INTERMEDIARIES

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

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

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

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


                                      C.20



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

                                      C.21



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.

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 re-designation 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
expense 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 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 C):

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 4.5% 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 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 (Re-designated Class R2) Contingent Deferred Sales Charge. Eliminate the
CDSC on Class R (re-designated 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.

                      (COMBINED PROXY STATEMENT/PROSPECTUS)
                                                                  April 17, 2009

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 reorganizations proposed in this combined proxy
statement/prospectus.

Q:   IS MY VOTE IMPORTANT?

Absolutely! While the Board of Directors (the "Board") of each Fund listed above
has reviewed these reorganizations 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 (a "Reorganization") of RiverSource Large Cap Equity Fund
  or Seligman Common Stock Fund, Inc. (each a "Selling Fund" and together, the
  "Selling Funds"), as applicable, into RiverSource Disciplined Equity Fund (the
  "Buying Fund") as noted in the table below:

<Table>
<Caption>
- ----------------------------------------------------------------------------------------------
 SELLING FUND                                    BUYING FUND
- ----------------------------------------------------------------------------------------------
                                              
RiverSource Large Cap Equity Fund
- -----------------------------------------------  RiverSource Disciplined Equity Fund
Seligman Common Stock Fund, Inc.
- ----------------------------------------------------------------------------------------------
</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 Buying Fund with the same aggregate net
asset value as your Selling Fund shares at the time of the Reorganization.
(Selling Funds and the Buying Funds may be individually or collectively referred
to as a "Fund" or the "Funds".)

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, LLC ("RiverSource Investments" or the "investment
manager"), a wholly-owned subsidiary of Ameriprise Financial, Inc. and the
investment manager of the 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 funds branded "Seligman" in addition to funds
branded "RiverSource." RiverSource Investments has proposed that certain
Seligman Funds and RiverSource Funds be reorganized into certain other Seligman
Funds or RiverSource Funds. The Reorganization of each Selling Fund into the
Buying Fund would result in a larger combined fund with 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 the
Reorganization, expenses of the larger combined fund are expected to be lower
than the expenses would have been for Seligman Common Stock Fund, Inc. and for
RiverSource Large Cap Equity 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?

After careful consideration, the Board of each Selling Fund recommends that you
vote FOR the Reorganization of your Selling 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.

INTRODUCTION TO PROPOSED FUND REORGANIZATION

Jan. 31, 2009

The accompanying unaudited pro forma combining statement of assets and
liabilities and the statement of operations reflect the accounts of the three
funds at and for the 12-month period ending Jan. 31, 2009. These statements have
been derived from financial statements prepared for RiverSource Disciplined
Equity Fund, RiverSource Large Cap Equity Fund and Seligman Common Stock Fund as
of Jan. 31, 2009. RiverSource Disciplined Equity Fund invests primarily in
equity securities of companies listed on U.S. exchanges with market
capitalizations greater than $5 billion at the time of purchase. RiverSource
Large Cap Equity Fund invests primarily in equity securities of companies with a
market capitalization greater than $5 billion at the time of purchase, which
includes income-producing equity securities, such as dividend paying stocks,
convertible securities and preferred stocks. Seligman Common Stock Fund invests
primarily in common stocks of larger U.S. companies with market capitalizations
over $3 billion at the time of purchase that are broadly diversified among a
number of industries.

Under the proposed Agreement and Plan of Reorganization, share classes of
RiverSource Large Cap Equity Fund and Seligman Common Stock Fund would be
exchanged for share classes of RiverSource Disciplined Equity Fund.

RIVERSOURCE DISCIPLINED EQUITY FUND (BUYING FUND)

RIVERSOURCE LARGE CAP EQUITY FUND (SELLING FUND)

SELIGMAN COMMON STOCK FUND (SELLING FUND)

NOTES TO PRO FORMA FINANCIAL STATEMENTS
(Unaudited as to Jan. 31, 2009)

1. BASIS OF COMBINATION

The unaudited pro forma combining statement of assets and liabilities and the
statement of operations reflect the accounts of the three funds at and for the
12-month period ending Jan. 31, 2009. These statements have been derived from
financial statements prepared for the RiverSource Disciplined Equity Fund,
RiverSource Large Cap Equity Fund and Seligman Common Stock Fund as of Jan. 31,
2009.

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 Disciplined Equity Fund invests primarily in equity securities of
companies listed on U.S. exchanges with market capitalizations greater than $5
billion at the time of purchase.

RiverSource Large Cap Equity Fund invests primarily in equity securities of
companies with a market capitalization greater than $5 billion at the time of
purchase, which includes income-producing equity securities, such as dividend
paying stocks, convertible securities and preferred stocks.

Seligman Common Stock Fund invests primarily in common stocks of larger U.S.
companies with market capitalizations over $3 billion at the time of purchase
that are broadly diversified among a number of industries.

The pro forma statements give effect to the proposed transfer of the assets and
liabilities of RiverSource Large Cap Equity Fund and Seligman Common Stock Fund
in exchange for Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4
and Class R5 shares of RiverSource Disciplined Equity Fund under U.S. generally
accepted accounting principles. The pro forma statements reflect estimates for
the combined RiverSource Disciplined Equity 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 Disciplined
Equity 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) for
    RiverSource Large Cap Equity Fund was removed and a new PIA adjustment was
    calculated based on the combined average net assets of the three funds and
    the RiverSource Disciplined Equity Fund PIA rate as of Jan. 31, 2009.

(b) To reflect the change in transfer agent fees due to the Reorganization
    including adjusting for closed account fees for each RiverSource Large Cap
    Equity Fund and Seligman Common Stock 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 change in fees resulting
    from the Reorganization per the agreement (through July 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 $89,675, none of
    which are recurring expenses.

taken place on Jan. 31, 2009. The following table reflects the number of

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.

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.
