* Not annualized.

The performance information shown represents past performance and is not a
guarantee of future results. The investment return and principal value of your
investment will fluctuate so that your shares, when redeemed, may be worth more
or less than their original cost. Current performance may be lower or higher
than the performance information shown. You may obtain performance information
current to the most recent month-end by contacting your financial intermediary,
visiting riversource.com/funds or calling 1(800) 221-2450.

The 5.75% sales charge applicable to Class A shares of the Fund is not reflected
in the table above. If reflected, returns would be lower than those shown. The
performance of other classes may vary from that shown because of differences in
fees and expenses. The Fund's returns reflect the effect of fee waivers/expense
reimbursements, if any. Without such waivers/reimbursements, the Fund's returns
would be lower. See the Average Annual Total Returns table for performance of
other share classes of the Fund.

The indices do not reflect the effects of sales charges, expenses (excluding
Lipper) and taxes. It is not possible to invest directly in an index.

Shading within the style matrix approximates areas in which the Fund is designed
to generally invest.

The style matrix can be a valuable tool for constructing and monitoring your
portfolio. It provides a frame of reference for distinguishing the types of
stocks or bonds owned by a mutual fund, and may serve as a guideline for helping
you build a portfolio.

Investment products, including shares of mutual funds, are not federally or
FDIC-insured, are not deposits or obligations of, or guaranteed by any financial
institution, and involve investment risks including possible loss of principal
and fluctuation in value.

Investments in small- and mid-capitalization companies often involve greater
risks and potential volatility than investments in larger, more established
companies.

6  RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2010 SEMIANNUAL
REPORT



FUND EXPENSES EXAMPLE ----------------------------------------------------------
(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1) fees;
and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the ongoing expenses of any funds in which the Fund
invests (also referred to as "acquired funds"), including affiliated and non-
affiliated pooled investment vehicles (including mutual funds and exchange
traded funds). The Fund's indirect expense from investing in the acquired funds
is based on the Fund's pro rata portion of the ongoing expenses charged by
acquired funds using the expense ratio of each of the acquired funds as of the
acquired fund's most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months Jan. 31, 2010.

ACTUAL EXPENSES
The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Direct expenses paid during the period" to
estimate the expenses you paid on your account during this period. You can also
estimate the direct and indirect expenses you paid over the period by using the
number in the first line under the heading "Direct and indirect expenses paid
during the period."

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(g)  Shareholders of tracking stocks have a financial interest only in a unit or
     division of the company. Unlike the common stock of the company itself, a
     tracking stock usually has limited or no voting rights. In the event of a
     company's liquidation, tracking stock shareholders typically do not have a
     legal claim on the company's assets.

(h)  At Jan. 31, 2010, the cost of securities for federal income tax purposes
     was approximately $115,571,000 and the approximate aggregate gross

FAIR VALUE MEASUREMENTS


Generally accepted accounting principles (GAAP) require disclosure regarding the
inputs and valuation techniques used to measure fair value and any changes in
valuation inputs or techniques. In addition, investments shall be disclosed by
major category.

The Fund categorizes its fair value measurements according to a three-level
hierarchy that maximizes the use of observable inputs and minimizes the use of
unobservable inputs by prioritizing that the most observable input be used when
available. Observable inputs are those that market participants would use in
pricing an investment based on market data obtained from sources independent of
the reporting entity. Unobservable inputs are those that reflect the Fund's
assumptions about the information market participants would use in pricing an
investment. An investment's level within the fair value hierarchy is based on
the lowest level of any input that is deemed significant to the asset or
liability's fair value measurement. The input levels are not necessarily an
indication of the risk or liquidity associated with investments at that level.
For example, certain U.S. government securities are generally high quality and
liquid, however, they are reflected as Level 2 because the inputs used to
determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

     - Level 1 -- Valuations based on quoted prices for investments in active
       markets that the Fund has the ability to access at the measurement date.
       Valuation adjustments are not applied to Level 1 investments.

     - Level 2 -- Valuations based on other significant observable inputs
       (including quoted prices for similar securities, interest rates,
       prepayment speeds, credit risks, etc.).

     - Level 3 -- Valuations based on significant unobservable inputs (including
       the Fund's own assumptions and judgment in determining the fair value of
       investments).

Inputs that are used in determining fair value of an investment may include
price information, credit data, volatility statistics, and other factors. These
inputs can be either observable or unobservable. The availability of observable
inputs can vary between investments, and is affected by various factors such as
the type of investment, and the volume and level of activity for that investment
or similar investments in the marketplace. The inputs will be considered by the
Fund Administrator, along with any other relevant factors in the calculation of
an investment's fair value. The Fund uses prices and inputs that are current as
of the measurement date, which may include periods of market dislocations.
During these periods, the availability of prices and inputs may be reduced for
many investments. This condition could cause an investment to be reclassified
between the various levels within the hierarchy.

Non-U.S. equity securities actively traded in foreign markets may be reflected
in Level 2 despite the availability of closing prices, because the Fund
evaluates and determines whether those closing prices reflect fair value at the
close of the New York Stock Exchange (NYSE) or require adjustment, as described
in Note 2 to the financial statements -- Valuation of securities.

Investments falling into the Level 3 category are primarily supported by quoted
prices from brokers and dealers participating in the market for those
investments. However, these may be classified as

FAIR VALUE MEASUREMENTS (CONTINUED)




Level 3 investments due to lack of market transparency and corroboration to
support these quoted prices. Additionally, valuation models may be used as the
pricing source for any remaining investments classified as Level 3. These models
rely on one or more significant unobservable inputs and/or significant
assumptions by the Fund Administrator. Inputs used in a valuation model may
include, but are not limited to, financial statement analysis, discount rates
and estimated cash flows, and comparable company data.

The following table is a summary of the inputs used to value the Fund's
investments as of Jan. 31, 2010:

FINANCIAL HIGHLIGHTS -----------------------------------------------------------

The following tables are intended to help you understand the Fund's financial
performance. Certain information reflects financial results for a single share
of a class held for the periods shown. For periods ended 2007 and after, per
share net investment income (loss) amounts are calculated based on average
shares outstanding during the period. Total returns assume reinvestment of all
dividends and distributions. Total returns do not reflect payment of sales
charges, if any, and are not annualized for periods of less than one year.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ADOPTION OF NEW ACCOUNTING STANDARD
In June 2009, the Financial Accounting Standards Board (FASB) established the
FASB Accounting Standards Codification(TM )(Codification) as the single source
of authoritative accounting principles recognized by the FASB in the preparation
of financial statements in conformity with U.S. generally accepted accounting
principles (GAAP). The Codification supersedes existing non-grandfathered, non-
SEC accounting and reporting standards. The Codification did not change GAAP
but, rather, organized it into a hierarchy where all guidance within the
Codification carries an equal level of authority. The Codification became
effective for financial statements issued for interim and annual periods ending
after Sept. 15, 2009. The Codification did not have an effect on the Fund's
financial statements.

USE OF ESTIMATES
Preparing financial statements that conform to U.S. generally accepted
accounting principles requires management to make estimates (e.g., on assets,
liabilities and contingent assets and liabilities) that could differ from actual
results.

VALUATION OF SECURITIES
All securities are valued at the close of business of the New York Stock
Exchange (NYSE). Securities traded on national securities exchanges or included
in national market systems are valued at the last quoted sales price from the
primary exchange. Debt securities are generally traded in the over-the-counter
market and are valued by an independent pricing service using an evaluated bid.
When market quotes are not readily available, the pricing service, in
determining fair values of debt securities, takes into consideration such
factors as current quotations by broker/dealers, coupon, maturity, quality, type
of issue, trading characteristics, and other yield and risk factors it deems
relevant in determining valuations. Foreign securities are valued based on
quotations from the principal market in which such securities are normally
traded. The procedures adopted by the Board generally contemplate the use of
fair valuation in the event that price quotations or valuations are not readily
available, price quotations or valuations from other sources are not reflective
of market value and thus deemed unreliable, or a significant event has occurred
in relation to a security or class of securities (such as foreign securities)
that is not reflected in price quotations or valuations from other sources. A
fair value price is a good faith estimate of the value of a security at a given
point in time.

Many securities markets and exchanges outside the U.S. close prior to the close
of the NYSE and therefore the closing prices for securities in such markets or
on

- --------------------------------------------------------------------------------
RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2010 SEMIANNUAL
                                                                      REPORT  33



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------



such exchanges may not fully reflect events that occur after such close but
before the close of the NYSE, including significant movements in the U.S. market
after foreign exchanges have closed. Accordingly, in those situations,
Ameriprise Financial, Inc. (Ameriprise Financial), parent company of the
Investment Manager, as administrator to the Fund, will fair value foreign
securities pursuant to procedures adopted by the Board, including utilizing a
third party pricing service to determine these fair values. These procedures
take into account multiple factors, including movements in the U.S. securities
markets, to determine a good faith estimate that reasonably reflects the current
market conditions as of the close of the NYSE.

Short-term securities maturing in more than 60 days from the valuation date are
valued at the market price or approximate market value based on current interest
rates. Typically, those maturing in 60 days or less that originally had
maturities of more than 60 days at acquisition date are valued at amortized cost
using the market value on the 61st day before maturity. Short-term securities
maturing in 60 days or less at acquisition date are valued at amortized cost.
Amortized cost is an approximation of market value. Investments in money market
funds are valued at net asset value.

FOREIGN CURRENCY TRANSLATIONS
Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the Statement of Operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes.

GUARANTEES AND INDEMNIFICATIONS
Under the Fund's organizational documents, its officers and directors are
indemnified against certain liabilities arising out of the performance of their
duties to the Fund. In addition, certain of the Fund's contracts with its
service providers contain general indemnification clauses. The Fund's maximum
exposure under these arrangements is unknown since the amount of any future
claims that may be made against the Fund cannot be determined and the Fund has
no historical basis for predicting the likelihood of any such claims.

FEDERAL TAXES
The Fund's policy is to comply with Subchapter M of the Internal Revenue Code
that applies to regulated investment companies and to distribute substantially
all of its taxable income (which includes net short-term capital gains) to
shareholders. No provision for income or excise taxes is thus required.

Management of the Fund has concluded that there are no significant uncertain tax
positions that would require recognition in the financial statements. Generally,
the tax authorities can examine all tax returns filed for the last three years.

RECENT ACCOUNTING PRONOUNCEMENT
On Jan. 21, 2010, the FASB issued an Accounting Standards Update (the
amendment), Fair Value Measurements and Disclosures (Topic 820): Improving
Disclosures about Fair Value Measurements, which provides guidance on how
investment assets and liabilities are to be valued and disclosed. Specifically,
the amendment requires reporting entities to disclose the input and valuation
techniques used to measure fair value for both recurring and nonrecurring fair
value measurements for Level 2 or Level 3 positions. The amendment also requires
that transfers between all levels (including Level 1 and Level 2) be disclosed
on a gross basis (i.e., transfers out must be disclosed separately from
transfers in), and the reason(s) for the transfer. Additionally purchases,
sales, issuances and settlements must be disclosed on a gross basis in the Level
3 rollforward. The effective date of the amendment is for interim and annual
periods beginning after Dec. 15, 2009, however, the requirement to provide the
Level 3 activity for purchases, sales, issuances and settlements on a gross
basis will be effective for interim and annual periods beginning after Dec. 15,
2010. At this time the Fund is evaluating the implications of the amendment and
the impact to the financial statements.

DIVIDENDS TO SHAREHOLDERS
An annual dividend from net investment income, declared and paid at the end of
the calendar year, when available, is reinvested in additional shares of the
Fund at net asset value or payable in cash. Capital gains, when available, are
distributed along with the income dividend.

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date and interest income,
including amortization of premium, market discount and original issue discount
using the effective interest method, is accrued daily.

NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


3. INVESTMENTS IN DERIVATIVES

The Fund may invest in certain derivative instruments, which are transactions
whose values depend on or are derived from (in whole or in part) the value of
one or more other assets, such as securities, currencies, commodities or
indices. Such derivative instruments may be used to maintain cash reserves while
maintaining exposure to certain other assets, to offset anticipated declines in
values of investments, to facilitate trading, to reduce transaction costs, and
to pursue higher investment returns. The Fund may also use derivative
instruments to mitigate certain investment risks, such as foreign currency
exchange rate risk, interest rate risk, and credit risk. Investments in
derivative instruments may expose the Fund to certain additional risks,
including those detailed below.

FUTURES TRANSACTIONS
The Fund may buy and sell financial futures contracts traded on any U.S. or
foreign exchange to produce incremental earnings, hedge existing positions or
protect against market changes in the value of equities, interest rates or
foreign currencies. The Fund may also buy and write put and call options on
these futures contracts. A futures contract represents a commitment for the
future purchase or sale of an asset at a specified price on a specified date.

Futures and options on futures are valued daily based upon the last sale price
at the close of the market on the principal exchange on which they are traded.
Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

Upon entering into futures contracts, the Fund bears the risk of interest rates,
exchange rates or securities prices moving unexpectedly, in which case, the Fund
may not achieve the anticipated benefits of the futures contracts and may
realize a loss. Additional risks include counterparty credit risk, the
possibility of an illiquid market, and that a change in the value of the
contract or option may not correlate with changes in the value of the underlying
securities.

4. EXPENSES AND SALES CHARGES

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is an annual fee that is equal to a percentage of the Fund's average daily net

- --------------------------------------------------------------------------------
RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2010 SEMIANNUAL
                                                                      REPORT  37



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


assets that declines from 0.70% to 0.475% as the Fund's net assets increase. The
fee may be adjusted upward or downward by a performance incentive adjustment
determined monthly by measuring the percentage difference over a rolling 12-
month period between the annualized performance of one Class A share of the Fund
and the annualized performance of the Lipper Mid-Cap Core Funds Index. In
certain circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year. If the performance difference is less than 0.50%,
the adjustment will be zero. The adjustment decreased the management fee by
$87,128 for the six months ended Jan. 31, 2010. The management fee for the six
months ended Jan. 31, 2010 was 0.57% of the Fund's average daily net assets,
including the adjustment under the terms of the performance incentive
arrangement.

ADMINISTRATIVE SERVICES FEES
Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
an annual fee for administration and accounting services equal to a percentage
of the Fund's average daily net assets that declines from 0.06% to 0.03% as the
Fund's net assets increase. The fee for the six months ended Jan. 31, 2010 was
0.06% of the Fund's average daily net assets.

OTHER FEES
Other expenses are for, among other things, certain expenses of the Fund or the
Board including: Fund boardroom and office expense, employee compensation,
employee health and retirement benefits, and certain other expenses. Payment of
these Fund and Board expenses is facilitated by a company providing limited
administrative services to the Fund and the Board. For the six months ended Jan.
31, 2010, other expenses paid to this company were $377.

COMPENSATION OF BOARD MEMBERS
Under a Deferred Compensation Plan (the Plan), the board members who are not
"interested persons" of the Fund under the 1940 Act may defer receipt of their
compensation. Deferred amounts are treated as though equivalent dollar amounts
had been invested in shares of the Fund or other funds in the RiverSource Family
of Funds. The Fund's liability for these amounts is adjusted for market value
changes and remains in the funds until distributed in accordance with the Plan.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains Fund shareholder accounts and records and provides Fund
shareholder services. The Fund pays the Transfer Agent an annual account-based
fee at a rate equal to $19.50 for Class A, $20.50 for Class B and $20.00 for
Class C for this service. The Transfer Agent also charges an annual fee of $3
per account serviced directly by the Fund or its designated agent for Class A,

- --------------------------------------------------------------------------------
38  RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2010 SEMIANNUAL
REPORT



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



Class B and Class C shares. The Fund also pays the Transfer Agent an annual
asset-based fee at a rate of 0.05% of the Fund's average daily net assets
attributable to Class R4 shares and an annual asset-based fee at a rate of 0.20%
of the Fund's average daily net assets attributable to Class W shares. The
Transfer Agent charges an annual fee of $5 per inactive account, charged on a
pro rata basis for the 12 month period from the date the account becomes
inactive. These fees are included in the transfer agency fees in the Statement
of Operations.

PLAN ADMINISTRATION SERVICES FEES
Under a Plan Administration Services Agreement with the Transfer Agent, the Fund
pays an annual fee at a rate of 0.25% of the Fund's average daily net assets
attributable to Class R4 shares for the provision of various administrative,
recordkeeping, communication and educational services.

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Fund Distributors, Inc. (the
Distributor) for distribution and shareholder services. Under a Plan and
Agreement of Distribution pursuant to Rule 12b-1, the Fund pays a fee at an
annual rate of up to 0.25% of the Fund's average daily net assets attributable
to Class A and Class W shares and a fee at an annual rate of up to 1.00% of the
Fund's average daily net assets attributable to Class B and Class C shares. For
Class B and Class C shares, of the 1.00% fee, up to 0.75% is reimbursed for
distribution expenses.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed (unreimbursed expense) was approximately $53,000 and $4,000 for Class
B and Class C shares, respectively. These amounts are based on the most recent
information available as of Oct. 31, 2009, and may be recovered from future
payments under the distribution plan or CDSC. To the extent the unreimbursed
expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges, including front-end and CDSCs, received by the Distributor for
distributing Fund shares were $13,605 for Class A and $210 for Class B for the
six months ended Jan. 31, 2010.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
The Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses until Sept. 30, 2010, unless sooner terminated at the
sole discretion of the Board, such that net expenses (excluding fees and
expenses of acquired funds*), before giving effect to any performance incentive

net assets:

*   In addition to the fees and expenses which the Fund bears directly, the Fund
    indirectly bears a pro rata share of the fees and expenses of the funds in
    which it invests (also referred to as "acquired funds"), including
    affiliated and non-affiliated pooled investment vehicles (including mutual
    funds and exchange traded funds). Because the acquired funds 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
    indirectly by the Fund will vary.

5. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $55,526,387 and $107,369,286, respectively, for the six
months ended Jan. 31, 2010. Realized gains and losses are determined on an
identified cost basis.

7. LENDING OF PORTFOLIO SECURITIES

The Fund has entered into a Master Securities Lending Agreement (the Agreement)
with JPMorgan Chase Bank, National Association (JPMorgan). The Agreement
authorizes JPMorgan as lending agent to lend securities to authorized borrowers
in order to generate additional income on behalf of the Fund. Pursuant to the
Agreement, the securities loaned are secured by cash or U.S. government
securities equal to at least 100% of the market value of the loaned securities.
Any additional collateral required to maintain those levels due to market
fluctuations of the loaned securities is delivered the following business day.
Cash collateral received is invested by the lending agent on behalf of the Fund
into authorized investments pursuant to the Agreement. The investments made with
the cash collateral are listed in the Portfolio of Investments. The values of
such investments and any uninvested cash collateral balance are disclosed in the
Statement of Assets and Liabilities along with the related obligation to return
the collateral upon the return of the securities loaned. At Jan. 31, 2010,
securities valued at $13,359,452 were on loan, secured by cash collateral of
$13,845,107 invested in short-term securities or in cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the
securities may occur should the borrower of the securities fail financially.
Risks may also arise to the extent that the value of the securities loaned
increases above the value of the collateral received. JPMorgan will indemnify
the Fund from losses resulting from a borrower's failure to return a loaned
security when due. Such

                                                                      REPORT  41



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------



indemnification does not extend to losses associated with declines in the value
of cash collateral investments. Loans are subject to termination by the Fund or
the borrower at any time, and are, therefore, not considered to be illiquid
investments.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Net income of
$61,974 earned from securities lending for the six months ended Jan. 31, 2010 is
included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

8. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund,
a money market fund established for the exclusive use of the funds in the
RiverSource Family of Funds and other institutional clients of RiverSource
Investments. The cost of the Fund's purchases and proceeds from sales of shares
of RiverSource Short-Term Cash Fund aggregated $25,329,391 and $24,992,513,
respectively, for the six months ended Jan. 31, 2010. The income distributions
received with respect to the Fund's investment in RiverSource Short-Term Cash
Fund can be found in the Statement of Operations and the Fund's invested balance
in RiverSource Short-Term Cash Fund at Jan. 31, 2010, can be found in the
Portfolio of Investments.

9. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility became effective on Oct.
15, 2009, replacing a prior credit facility. The credit facility agreement,
which is a collective agreement between the Fund and certain other funds in the
RiverSource Family of Funds, severally and not jointly, permits collective
borrowings up to $300 million. The borrowers shall have the right, upon written
notice to the Administrative Agent to request an increase of up to $200 million
in the aggregate amount of the credit facility from new or existing lenders,
provided that the aggregate amount of the credit facility shall at no time
exceed $500 million. Participation in such increase by any existing lender shall
be at such lender's sole discretion. Interest is charged to each Fund based on
its borrowings at a rate equal to the sum of the federal funds rate plus (i)
1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the

of such excess. Each borrowing under the credit facility matures no later than
60 days after the date of borrowing. The Fund also pays a commitment fee equal
to its pro rata share of the amount of the credit facility at a rate of 0.10%
per annum, in addition to an upfront fee equal to its pro rata share of 0.04% of
the amount of the credit facility. Prior to Oct. 15, 2009, the credit facility
agreement, which was a collective agreement between the Fund and certain other
funds in the RiverSource Family of Funds, severally and not jointly, permitted
collective borrowings up to $475 million. Interest was charged to each Fund
based on its borrowings at a rate equal to the federal funds rate plus 0.75%.
The Fund also paid a commitment fee equal to its pro rata share of the amount of
the credit facility at a rate of 0.06% per annum, in addition to an upfront fee
equal to its pro rata share of 0.02% of the amount of the credit facility. The
Fund had no borrowings during the six months ended Jan. 31, 2010.

10. FEDERAL TAX INFORMATION

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of futures contracts,
passive foreign investment company (PFIC) holdings, re-characterization of real
estate investment trust (REIT) distributions, post-October losses and losses
deferred due to wash sales. The character of distributions made during the year
from net investment income or net realized gains may differ from their ultimate
characterization for federal income tax purposes. Also, due to the timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the year that the income or realized gains (losses) were recorded by
the Fund.

For federal income tax purposes, the Fund had a capital loss carry-over of
$21,435,234 at July 31, 2009, that if not offset by capital gains will expire as
follows:

<Table>
<Caption>
  2014       2015        2016           2017
                           
$93,125    $21,904    $2,186,828    $19,133,377
</Table>


Because the measurement periods for a regulated investment company's income are
different for excise tax purposes versus income tax purposes, special rules are
in place to protect the amount of earnings and profits needed to support excise
tax distributions. As a result, the Fund is permitted to treat net capital
losses realized between Nov. 1, 2008 and its fiscal year end (post-October loss)
as occurring on the first day of the following tax year. At July 31, 2009, the
Fund had a post-October loss of $15,728,006 that is treated for income tax
purposes as occurring on Aug. 1, 2009.

NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires. There is no assurance that the Fund will be able to utilize all of its
capital loss carry-over before it expires.

11. SUBSEQUENT EVENTS

Management has evaluated Fund related events and transactions that occurred
during the period from the date of the Statement of Assets and Liabilities
through the date of issuance of the Fund's financial statements. There were no
events or transactions that occurred during the period that materially impacted
the amounts or disclosures in the Fund's financial statements.

12. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc. was filed in the
United States District Court for the District of Arizona. The plaintiffs allege
that they are investors in several American Express Company (now known as
RiverSource) mutual funds and they purport to bring the action derivatively on
behalf of those funds under the Investment Company Act of 1940. The plaintiffs
allege that fees allegedly paid to the defendants by the funds for investment
advisory and administrative services are excessive. The plaintiffs seek remedies
including restitution and rescission of investment advisory and distribution
agreements. The plaintiffs voluntarily agreed to transfer this case to the
United States District Court for the District of Minnesota (the District Court).
In response to defendants' motion to dismiss the complaint, the District Court
dismissed one of plaintiffs' four claims and granted plaintiffs limited
discovery. Defendants moved for summary judgment in April 2007. Summary judgment
was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a
notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit)
on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary
judgment and remanded to the District Court for further proceedings. On August
6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court,
asking the U.S. Supreme Court to stay the District Court proceedings while the
U.S. Supreme Court considers and rules in a case captioned Jones v. Harris
Associates, which involves issues of law similar to those presented in the
Gallus case.

In December 2005, without admitting or denying the allegations, American Express
Financial Corporation (AEFC, which is now known as Ameriprise

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

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




Financial, Inc. (Ameriprise Financial)), entered into settlement agreements with
the Securities and Exchange Commission (SEC) and Minnesota Department of
Commerce (MDOC) related to market timing activities. As a result, AEFC was
censured and ordered to cease and desist from committing or causing any
violations of certain provisions of the Investment Advisers Act of 1940, the
Investment Company Act of 1940, and various Minnesota laws. AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to retain an independent distribution consultant to assist in developing
a plan for distribution of all disgorgement and civil penalties ordered by the
SEC in accordance with various undertakings detailed at
http://www.sec.gov/litigation/admin/ia-2451.pdf. Ameriprise Financial and its
affiliates have cooperated with the SEC and the MDOC in these legal proceedings,
and have made regular reports to the RiverSource Funds' Boards of
Directors/Trustees.

On November 7, 2008, RiverSource Investments, LLC, a subsidiary of Ameriprise
Financial, Inc., acquired J. & W. Seligman & Co. Incorporated (Seligman). In
late 2003, Seligman conducted an extensive internal review concerning mutual
fund trading practices. Seligman's review, which covered the period 2001-2003,
noted one arrangement that permitted frequent trading in certain open-end
registered investment companies managed by Seligman (the Seligman Funds); this
arrangement was in the process of being closed down by Seligman before September
2003. Seligman identified three other arrangements that permitted frequent
trading, all of which had been terminated by September 2002. In January 2004,
Seligman, on a voluntary basis, publicly disclosed these four arrangements to
its clients and to shareholders of the Seligman Funds. Seligman also provided
information concerning mutual fund trading practices to the SEC and the Office
of the Attorney General of the State of New York (NYAG).

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc. (now known as RiverSource Fund
Distributors, Inc.), Seligman Data Corp. and Brian T. Zino (collectively, the
Seligman Parties), alleging, in substance, that the Seligman Parties permitted
various persons to engage in frequent trading and, as a result, the prospectus
disclosure used by the registered investment companies then managed by Seligman
was and had been misleading. The NYAG included other related claims and also
claimed that the fees charged by Seligman to the Seligman Funds were excessive.
On March 13, 2009, without admitting or denying any violations of law or
wrongdoing, the Seligman Parties entered into a stipulation of settlement with
the NYAG and settled the claims made by the NYAG. Under the terms of the
settlement, Seligman paid $11.3 million to four

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

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

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse effect
on the Funds or the ability of Ameriprise Financial or its affiliates to perform
under their contracts with the Funds, these proceedings are subject to
uncertainties and, as such, we are unable to estimate the possible loss or range
of loss that may result. An adverse outcome in one or more of these proceedings
could result in adverse judgments, settlements, fines, penalties or other relief
that could have a material adverse effect on the consolidated financial
condition or results of operations of Ameriprise Financial.

The performance information shown represents past performance and is not a
guarantee of future results. The investment return and principal value of your
investment will fluctuate so that your shares, when redeemed, may be worth more
or less than their original cost. Current performance may be lower or higher

The 5.75% sales charge applicable to Class A shares of the Fund is not reflected
in the table above. If reflected, returns would be lower than those shown. The
performance of other classes may vary from that shown because of differences in
fees and expenses. The Fund's returns reflect the effect of fee waivers/expense
reimbursements, if any. Without such waivers/reimbursements, the Fund's returns
would be lower. See the Average Annual Total Returns table for performance of

(1) The Russell 2000 Value Index, an unmanaged index, measures the performance
    of those Russell 2000 companies with lower price-to-book ratios and lower
    forecasted growth values. The index reflects reinvestment of all
    distributions and changes in market prices.
(2) The Lipper Small-Cap Value Funds Index includes the 30 largest small-cap
    value funds tracked by Lipper Inc. The index's returns include net
    reinvested dividends. The Fund's performance is currently measured against
    this index for purposes of determining the performance incentive adjustment.

Shading within the style matrix approximates areas in which the Fund is designed
to generally invest.

The style matrix can be a valuable tool for constructing and monitoring your
portfolio. It provides a frame of reference for distinguishing the types of
stocks or bonds owned by a mutual fund, and may serve as a guideline for helping
you build a portfolio.

Investment products, including shares of mutual funds, are not federally or
FDIC-insured, are not deposits or obligations of, or guaranteed by any financial
institution, and involve investment risks including possible loss of principal
and fluctuation in value.




Investments in small-capitalization companies often involve greater risks and
potential volatility than investments in larger, more established companies.

6  RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT



FUND EXPENSES EXAMPLE ----------------------------------------------------------
(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1) fees;
and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the ongoing expenses of any funds in which the Fund
invests (also referred to as "acquired funds"), including affiliated and non-
affiliated pooled investment vehicles (including mutual funds and exchange
traded funds). The Fund's indirect expense from investing in the acquired funds
is based on the Fund's pro rata portion of the ongoing expenses charged by
acquired funds using the expense ratio of each of the acquired funds as of the
acquired fund's most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months Jan. 31, 2010.

ACTUAL EXPENSES
The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Direct expenses paid during the period" to
estimate the expenses you paid on your account during this period. You can also
estimate the direct and indirect expenses you paid over the period by using the
number in the first line under the heading "Direct and indirect expenses paid
during the period."

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

FAIR VALUE MEASUREMENTS


Generally accepted accounting principles (GAAP) require disclosure regarding the
inputs and valuation techniques used to measure fair value and any changes in
valuation inputs or techniques. In addition, investments shall be disclosed by
major category.

The Fund categorizes its fair value measurements according to a three-level
hierarchy that maximizes the use of observable inputs and minimizes the use of
unobservable inputs by prioritizing that the most observable input be used when
available. Observable inputs are those that market participants would use in
pricing an investment based on market data obtained from sources independent of
the reporting entity. Unobservable inputs are those that reflect the Fund's
assumptions about the information market participants would use in pricing an
investment. An investment's level within the fair value hierarchy is based on
the lowest level of any input that is deemed significant to the asset or
liability's fair value measurement. The input levels are not necessarily an
indication of the risk or liquidity associated with investments at that level.
For example, certain U.S. government securities are generally high quality and
liquid, however, they are reflected as Level 2 because the inputs used to
determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

     - Level 1 -- Valuations based on quoted prices for investments in active
       markets that the Fund has the ability to access at the measurement date.
       Valuation adjustments are not applied to Level 1 investments.

     - Level 2 -- Valuations based on other significant observable inputs
       (including quoted prices for similar securities, interest rates,
       prepayment speeds, credit risks, etc.).

     - Level 3 -- Valuations based on significant unobservable inputs (including
       the Fund's own assumptions and judgment in determining the fair value of
       investments).

Inputs that are used in determining fair value of an investment may include
price information, credit data, volatility statistics, and other factors. These
inputs can be either observable or unobservable. The availability of observable
inputs can vary between investments, and is affected by various factors such as
the type of investment, and the volume and level of activity for that investment
or similar investments in the marketplace. The inputs will be considered by the
Fund Administrator, along with any other relevant factors in the calculation of
an investment's fair value. The Fund uses prices and inputs that are current as
of the measurement date, which may include periods of market dislocations.
During these periods, the availability of prices and inputs may be reduced for
many investments. This condition could cause an investment to be reclassified
between the various levels within the hierarchy.

Non-U.S. equity securities actively traded in foreign markets may be reflected
in Level 2 despite the availability of closing prices, because the Fund
evaluates and determines whether those closing prices reflect fair value at the
close of the New York Stock Exchange (NYSE) or require adjustment, as described
in Note 2 to the financial statements -- Valuation of securities.

Investments falling into the Level 3 category are primarily supported by quoted
prices from brokers and dealers participating in the market for those
investments. However, these may be classified as

- --------------------------------------------------------------------------------
18  RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT



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

FAIR VALUE MEASUREMENTS (CONTINUED)




Level 3 investments due to lack of market transparency and corroboration to
support these quoted prices. Additionally, valuation models may be used as the
pricing source for any remaining investments classified as Level 3. These models
rely on one or more significant unobservable inputs and/or significant
assumptions by the Fund Administrator. Inputs used in a valuation model may
include, but are not limited to, financial statement analysis, discount rates
and estimated cash flows, and comparable company data.

The following table is a summary of the inputs used to value the Fund's
investments as of
Jan. 31, 2010:

FINANCIAL HIGHLIGHTS -----------------------------------------------------------

The following tables are intended to help you understand the Fund's financial
performance. Certain information reflects financial results for a single share
of a class held for the periods shown. For periods ended 2007 and after, per
share net investment income (loss) amounts are calculated based on average
shares outstanding during the period. Total returns assume reinvestment of all
dividends and distributions. Total returns do not reflect payment of sales
charges, if any, and are not annualized for periods of less than one year.

NOTES TO FINANCIAL STATEMENTS --------------------------------------------------
(UNAUDITED AS OF JAN. 31, 2010)

1. ORGANIZATION

RiverSource Disciplined Small Cap Value Fund (the Fund) is a series of
RiverSource Dimensions Series, Inc. (the Corporation) and is registered under
the Investment Company Act of 1940, as amended (the 1940 Act) as a diversified,
open-end management investment company. The Corporation has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Corporation's Board of Directors (the Board). The
Fund invests primarily in small capitalization equity securities of companies
with market capitalizations that fall within the range of companies that
comprise the Russell 2000 Value Index at the time of investment.

The Fund offers Class A, Class B, Class C, Class I, Class R2, Class R3, Class R4
and Class R5 shares.

- -  Class A shares are offered with a front-end sales charge, which may be waived
   under certain circumstances.

- -  Class B shares may be subject to a contingent deferred sales charge (CDSC)
   and automatically convert to Class A shares one month after the completion of
   the eighth year of ownership if originally purchased in a RiverSource fund on
   or after May 21, 2005 or originally purchased in a Seligman fund on or after
   June 13, 2009. 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
   prior to June 13, 2009 will convert to Class A shares in the month prior to
   the ninth year of ownership.

- -  Class C shares may be subject to a CDSC.

- -  Class I, Class R2, Class R3, Class R4 and Class R5 shares are offered without
   a front-end sales charge or CDSC to qualifying institutional investors.

At Jan 31, 2010, RiverSource Investments, LLC (RiverSource Investments or the
Investment Manager) and affiliated funds-of-funds in the RiverSource Family of
Funds owned 100% of Class I shares, and the Investment Manager owned 100% of
Class R2, Class R4 and Class R5 shares. At Jan. 31, 2010, the Investment Manager
and affiliated funds-of-funds in the RiverSource Family of Funds owned
approximately 90% of the total outstanding Fund shares.

All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration services fees) differ among classes. Income, expenses
(other than class specific expenses) and realized and unrealized gains or losses
on

investments are allocated to each class of shares based upon its relative net
assets.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ADOPTION OF NEW ACCOUNTING STANDARD
In June 2009, the Financial Accounting Standards Board (FASB) established the
FASB Accounting Standards Codification(TM) (Codification) as the single source
of authoritative accounting principles recognized by the FASB in the preparation
of financial statements in conformity with U.S. generally accepted accounting
principles (GAAP). The Codification supersedes existing non-grandfathered, non-
SEC accounting and reporting standards. The Codification did not change GAAP
but, rather, organized it into a hierarchy where all guidance within the
Codification carries an equal level of authority. The Codification became
effective for financial statements issued for interim and annual periods ending
after Sept. 15, 2009. The Codification did not have an effect on the Fund's
financial statements.

USE OF ESTIMATES
Preparing financial statements that conform to U.S. generally accepted
accounting principles requires management to make estimates (e.g., on assets,
liabilities and contingent assets and liabilities) that could differ from actual
results.

VALUATION OF SECURITIES
All securities are valued at the close of business of the New York Stock
Exchange (NYSE). Securities traded on national securities exchanges or included
in national market systems are valued at the last quoted sales price from the
primary exchange. Debt securities are generally traded in the over-the-counter
market and are valued by an independent pricing service using an evaluated bid.
When market quotes are not readily available, the pricing service, in
determining fair values of debt securities, takes into consideration such
factors as current quotations by broker/dealers, coupon, maturity, quality, type
of issue, trading characteristics, and other yield and risk factors it deems
relevant in determining valuations. Foreign securities are valued based on
quotations from the principal market in which such securities are normally
traded. The procedures adopted by the Board generally contemplate the use of
fair valuation in the event that price quotations or valuations are not readily
available, price quotations or valuations from other sources are not reflective
of market value and thus deemed unreliable, or a significant event has occurred
in relation to a security or class of securities (such as foreign securities)
that is not reflected in price quotations or valuations

- --------------------------------------------------------------------------------
32  RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT



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


from other sources. A fair value price is a good faith estimate of the value of
a security at a given point in time.

Many securities markets and exchanges outside the U.S. close prior to the close
of the NYSE and therefore the closing prices for securities in such markets or
on such exchanges may not fully reflect events that occur after such close but
before the close of the NYSE, including significant movements in the U.S. market
after foreign exchanges have closed. Accordingly, in those situations,
Ameriprise Financial, Inc. (Ameriprise Financial), parent company of the
Investment Manager, as administrator to the Fund, will fair value foreign
securities pursuant to procedures adopted by the Board, including utilizing a
third party pricing service to determine these fair values. These procedures
take into account multiple factors, including movements in the U.S. securities
markets, to determine a good faith estimate that reasonably reflects the current
market conditions as of the close of the NYSE. The fair value of a security is
likely to be different from the quoted or published price, if available.

Short-term securities maturing in more than 60 days from the valuation date are
valued at the market price or approximate market value based on current interest
rates. Typically, those maturing in 60 days or less that originally had
maturities of more than 60 days at acquisition date are valued at amortized cost
using the market value on the 61st day before maturity. Short-term securities
maturing in 60 days or less at acquisition date are valued at amortized cost.
Amortized cost is an approximation of market value. Investments in money market
funds are valued at net asset value.

FOREIGN CURRENCY TRANSLATIONS
Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the Statement of Operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes.

GUARANTEES AND INDEMNIFICATIONS
Under the Fund's organizational documents, its officers and directors are
indemnified against certain liabilities arising out of the performance of their
duties to the Fund. In addition, certain of the Fund's contracts with its
service

- --------------------------------------------------------------------------------
      RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT  33



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

providers contain general indemnification clauses. The Fund's maximum exposure
under these arrangements is unknown since the amount of any future claims that
may be made against the Fund cannot be determined and the Fund has no historical
basis for predicting the likelihood of any such claims.

FEDERAL TAXES
The Fund's policy is to comply with Subchapter M of the Internal Revenue Code
that applies to regulated investment companies and to distribute substantially
all of its taxable income (which includes net short-term capital gains) to
shareholders. No provision for income or excise taxes is thus required.

Management of the Fund has concluded that there are no significant uncertain tax
positions that would require recognition in the financial statements. Generally,
the tax authorities can examine all tax returns filed for the last three years.

RECENT ACCOUNTING PRONOUNCEMENTS
On Jan. 21, 2010, the FASB issued an Accounting Standards Update (the
amendment), Fair Value Measurements and Disclosures (Topic 820): Improving
Disclosures about Fair Value Measurements, which provides guidance on how
investment assets and liabilities are to be valued and disclosed. Specifically,
the amendment requires reporting entities to disclose the input and valuation
techniques used to measure fair value for both recurring and nonrecurring fair
value measurements for Level 2 or Level 3 positions. The amendment also requires
that transfers between all levels (including Level 1 and Level 2) be disclosed
on a gross basis (i.e., transfers out must be disclosed separately from
transfers in), and the reason(s) for the transfer. Additionally purchases,
sales, issuances and settlements must be disclosed on a gross basis in the Level
3 rollforward. The effective date of the amendment is for interim and annual
periods beginning after Dec. 15, 2009, however, the requirement to provide the
Level 3 activity for purchases, sales, issuances and settlements on a gross
basis will be effective for interim and annual periods beginning after Dec. 15,
2010. At this time the Fund is evaluating the implications of the amendment and
the impact to the financial statements.

DIVIDENDS TO SHAREHOLDERS
An annual dividend from net investment income, declared and paid at the end of
the calendar year, when available, is reinvested in additional shares of the
Fund at net asset value or payable in cash. Capital gains, when available, are
distributed along with the income dividend.

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date and interest income,
including amortization of premium, market discount and original issue discount
using the effective interest method, is accrued daily.

3. INVESTMENTS IN DERIVATIVES

The Fund may invest in certain derivative instruments, which are transactions
whose values depend on or are derived from (in whole or in part) the value of
one or more other assets, such as securities, currencies, commodities or
indices. Such derivative instruments may be used to maintain cash reserves while
maintaining exposure to certain other assets, to offset anticipated declines in
values of investments, to facilitate trading, to reduce transaction costs, and
to pursue higher investment returns. The Fund may also use derivative
instruments to mitigate certain investment risks, such as foreign currency
exchange rate risk, interest rate risk, and credit risk. Investments in
derivative instruments may expose the Fund to certain additional risks,
including those detailed below.

FUTURES TRANSACTIONS
The Fund may buy and sell financial futures contracts traded on any U.S. or
foreign exchange to produce incremental earnings, hedge existing positions or
protect against market changes in the value of equities, interest rates or
foreign currencies. The Fund may also buy and write put and call options on
these futures contracts. A futures contract represents a commitment for the
future purchase or sale of an asset at a specified price on a specified date.

Futures and options on futures are valued daily based upon the last sale price
at the close of the market on the principal exchange on which they are traded.
Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

Upon entering into futures contracts, the Fund bears the risk of interest rates,
exchange rates or securities prices moving unexpectedly, in which case, the Fund
may not achieve the anticipated benefits of the futures contracts and may
realize a loss. Additional risks include counterparty credit risk, the
possibility of an illiquid market, and that a change in the value of the
contract or option may not correlate with changes in the value of the underlying
securities.

4. EXPENSES AND SALES CHARGES

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is an annual fee that is equal to a percentage of the Fund's average daily net
assets that declines from 0.85% to 0.725% as the Fund's net assets increase. The
fee may be adjusted upward or downward by a performance incentive adjustment
determined monthly by measuring the percentage difference over a rolling 12-
month period between the annualized performance of one Class A share of the Fund
and the annualized performance of the Lipper Small-Cap Value Funds Index. In
certain circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year. If the performance difference is less than 0.50%,
the adjustment will be zero. The adjustment decreased the management fee by
$27,616 for the six months ended Jan. 31, 2010. The management fee for the six
months ended Jan. 31, 2010 was 0.74% of the Fund's average daily net assets,
including the adjustment under the terms of the performance incentive
arrangement.

ADMINISTRATIVE SERVICES FEES
Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
an annual fee for administration and accounting services equal to a percentage
of the Fund's average daily net assets that declines from 0.08% to 0.05% as the
Fund's net assets increase. The fee for the six months ended Jan. 31, 2010 was
0.08% of the Fund's average daily net assets.

OTHER FEES
Other expenses are for, among other things, certain expenses of the Fund or the
Board including: Fund boardroom and office expense, employee compensation,
employee health and retirement benefits, and certain other expenses. Payment of
these Fund and Board expenses is facilitated by a company providing limited
administrative services to the Fund and the Board. For the six months ended Jan.
31, 2010, other expenses paid to this company were $123.

COMPENSATION OF BOARD MEMBERS
Under a Deferred Compensation Plan (the Plan), the board members who are not
"interested persons" of the Fund under the 1940 Act may defer receipt of their
compensation. Deferred amounts are treated as though equivalent dollar amounts
had been invested in shares of the Fund or other funds in the RiverSource Family


- --------------------------------------------------------------------------------
      RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT  37



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

of Funds. The Fund's liability for these amounts is adjusted for market value
changes and remains in the funds until distributed in accordance with the Plan.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains Fund shareholder accounts and records and provides Fund
shareholder services. The Fund pays the Transfer Agent an annual account-based
fee at a rate equal to $19.50 for Class A, $20.50 for Class B and $20.00 for
Class C for this service. The Transfer Agent also charges an annual fee of $3
per account serviced directly by the Fund or its designated agent for Class A,
Class B and Class C shares. The Fund also pays the Transfer Agent an annual
asset-based fee at a rate of 0.05% of the Fund's average daily net assets
attributable to Class R2, Class R3, Class R4 and Class R5 shares. The Transfer
Agent charges an annual fee of $5 per inactive account, charged on a pro rata
basis for the 12 month period from the date the account becomes inactive. These
fees are included in the transfer agency fees in the Statement of Operations.

PLAN ADMINISTRATION SERVICES FEES
Under a Plan Administration Services Agreement with the Transfer Agent, the Fund
pays an annual fee at a rate of 0.25% of the Fund's average daily net assets
attributable to Class R2, Class R3 and Class R4 shares for the provision of
various administrative, recordkeeping, communication and educational services.

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Fund Distributors, Inc. (the
Distributor) for distribution and shareholder services. Under a Plan and
Agreement of Distribution pursuant to Rule 12b-1, the Fund pays a fee at an
annual rate of up to 0.25% of the Fund's average daily net assets attributable
to Class A and Class R3 shares, a fee at an annual rate of up to 0.50% of the
Fund's average daily net assets attributable to Class R2 shares and a fee at an
annual rate of up to 1.00% of the Fund's average daily net assets attributable
to Class B and Class C shares. For Class B and Class C shares, of the 1.00% fee,
up to 0.75% is reimbursed for distribution expenses.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed (unreimbursed expense) was approximately $16,000 and $2,000 for Class
B and Class C shares, respectively. These amounts are based on the most recent
information available as of Oct. 31, 2009, and may be recovered from future
payments under the distribution plan or CDSC. To the extent the unreimbursed
expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges, including front-end and CDSCs, received by the Distributor for
distributing Fund shares were $3,485 for Class A and $13 for Class B for the six
months ended Jan. 31, 2010.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the six months ended Jan. 31, 2010, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds*), including the adjustment under
the terms of a performance incentive arrangement, were as follows:

<Table>

Class R3..............................................   $1
</Table>


The management fees waived/reimbursed at the Fund level were $20,365.

The Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses until Sept. 30, 2010, unless sooner terminated at the
sole discretion of the Board, such that net expenses (excluding fees and
expenses of acquired funds*), before giving effect to any performance incentive
adjustment, will not exceed the following percentage of the class' average daily
net assets:

<Table>
                                                    
Class A..............................................  1.49%

Class R2.............................................  1.84
Class R3.............................................  1.59
Class R4.............................................  1.34
Class R5.............................................  1.09
</Table>


*   In addition to the fees and expenses which the Fund bears directly, the Fund
    indirectly bears a pro rata share of the fees and expenses of the funds in
    which it invests (also referred to as "acquired funds"), including
    affiliated and non-affiliated pooled investment vehicles (including mutual
    funds and exchange traded funds). Because the acquired funds have varied
    expense and fee levels and the Fund may own

7. LENDING OF PORTFOLIO SECURITIES

The Fund has entered into a Master Securities Lending Agreement (the Agreement)
with JPMorgan Chase Bank, National Association (JPMorgan). The Agreement
authorizes JPMorgan as lending agent to lend securities to authorized borrowers
in order to generate additional income on behalf of the Fund. Pursuant to the
Agreement, the securities loaned are secured by cash or U.S. government
securities equal to at least 100% of the market value of the loaned securities.
Any additional collateral required to maintain those levels due to market
fluctuations of the loaned securities is delivered the following business day.
Cash collateral received is invested by the lending agent on behalf of the Fund
into authorized investments pursuant to the Agreement. The investments made with
the cash collateral are listed in the Portfolio of Investments. The values of
such investments and any uninvested cash collateral balance are disclosed in the
Statement of Assets and Liabilities along with the related obligation to return
the collateral upon the return of the securities loaned. At Jan. 31, 2010,
securities valued at $4,954,449 were on loan, secured by cash collateral of
$5,117,441 invested in short-term securities or in cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the
securities may occur should the borrower of the securities fail financially.
Risks may also arise to the extent that the value of the securities loaned
increases above the value of the collateral received. JPMorgan will indemnify
the Fund from losses resulting from a borrower's failure to return a loaned
security when due. Such indemnification does not extend to losses associated
with declines in the value of cash collateral investments. Loans are subject to
termination by the Fund or the borrower at any time, and are, therefore, not
considered to be illiquid investments.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Net income of
$49,483 earned from securities lending for the six months ended Jan. 31, 2010 is
included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

8. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund,
a money market fund established for the exclusive use of the funds in the
RiverSource Family of Funds and other institutional clients of RiverSource
Investments. The cost of the Fund's purchases and proceeds from sales of shares

- --------------------------------------------------------------------------------
      RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT  41



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


of RiverSource Short-Term Cash Fund aggregated $9,423,903 and $8,637,995,
respectively, for the six months ended Jan. 31, 2010. The income distributions
received with respect to the Fund's investment in RiverSource Short-Term Cash
Fund can be found in the Statement of Operations and the Fund's invested balance
in RiverSource Short-Term Cash Fund at Jan. 31, 2010, can be found in the
Portfolio of Investments.

9. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility became effective on Oct.
15, 2009, replacing a prior credit facility. The credit facility agreement,
which is a collective agreement between the Fund and certain other funds in the
RiverSource Family of Funds, severally and not jointly, permits collective
borrowings up to $300 million. The borrowers shall have the right, upon written
notice to the Administrative Agent to request an increase of up to $200 million
in the aggregate amount of the credit facility from new or existing lenders,
provided that the aggregate amount of the credit facility shall at no time
exceed $500 million. Participation in such increase by any existing lender shall
be at such lender's sole discretion. Interest is charged to each Fund based on
its borrowings at a rate equal to the sum of the federal funds rate plus (i)
1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the
amount of such excess. Each borrowing under the credit facility matures no later
than 60 days after the date of borrowing. The Fund also pays a commitment fee
equal to its pro rata share of the amount of the credit facility at a rate of
0.10% per annum, in addition to an upfront fee equal to its pro rata share of
0.04% of the amount of the credit facility. Prior to Oct. 15, 2009, the credit
facility agreement, which was a collective agreement between the Fund and
certain other funds in the RiverSource Family of Funds, severally and not
jointly, permitted collective borrowings up to $475 million. Interest was
charged to each Fund based on its borrowings at a rate equal to the federal
funds rate plus 0.75%. The Fund also paid a commitment fee equal to its pro rata
share of the amount of the credit facility at a rate of 0.06% per annum, in
addition to an upfront fee equal to its pro rata share of 0.02% of the amount of
the credit facility. The Fund had no borrowings during the six months ended Jan.
31, 2010.

10. FEDERAL TAX INFORMATION

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of futures contracts,

- --------------------------------------------------------------------------------
42  RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT



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



passive foreign investment company (PFIC) holdings, re-characterization of real
estate investment trust (REIT) distributions, post-October losses and losses
deferred due to wash sales. The character of distributions made during the year
from net investment income or net realized gains may differ from their ultimate
characterization for federal income tax purposes. Also, due to the timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the year that the income or realized gains (losses) were recorded by
the Fund.

For federal income tax purposes, the Fund had a capital loss carry-over of
$6,787,750 at July 31, 2009, that if not offset by capital gains will expire as
follows:


<Table>
<Caption>
  2016         2017
         
$554,680    $6,233,070
</Table>


Because the measurement periods for a regulated investment company's income are
different for excise tax purposes versus income tax purposes, special rules are
in place to protect the amount of earnings and profits needed to support excise
tax distributions. As a result, the Fund is permitted to treat net capital
losses realized between Nov. 1, 2008 and its fiscal year end (post-October loss)
as occurring on the first day of the following tax year. At July 31, 2009, the
Fund had a post-October loss of $7,832,894 that is treated for income tax
purposes as occurring on Aug. 1, 2009.

It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires. There is no assurance that the Fund will be able to utilize all of its
capital loss carry-over before it expires.

11. SUBSEQUENT EVENTS

Management has evaluated Fund related events and transactions that occurred
during the period from the date of the Statement of Assets and Liabilities
through the date of issuance of the Fund's financial statements. There were no
events or transactions that occurred during the period that materially impacted
the amounts or disclosures in the Fund's financial statements.

12. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc. was filed in the
United States District Court for the District of Arizona. The plaintiffs allege
that

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

NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


they are investors in several American Express Company (now known as
RiverSource) mutual funds and they purport to bring the action derivatively on
behalf of those funds under the Investment Company Act of 1940. The plaintiffs
allege that fees allegedly paid to the defendants by the funds for investment
advisory and administrative services are excessive. The plaintiffs seek remedies
including restitution and rescission of investment advisory and distribution
agreements. The plaintiffs voluntarily agreed to transfer this case to the
United States District Court for the District of Minnesota (the District Court).
In response to defendants' motion to dismiss the complaint, the District Court
dismissed one of plaintiffs' four claims and granted plaintiffs limited
discovery. Defendants moved for summary judgment in April 2007. Summary judgment
was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a
notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit)
on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary
judgment and remanded to the District Court for further proceedings. On August
6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court,
asking the U.S. Supreme Court to stay the District Court proceedings while the
U.S. Supreme Court considers and rules in a case captioned Jones v. Harris
Associates, which involves issues of law similar to those presented in the
Gallus case.

In December 2005, without admitting or denying the allegations, American Express
Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc.
(Ameriprise Financial)), entered into settlement agreements with the Securities
and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC)
related to market timing activities. As a result, AEFC was censured and ordered
to cease and desist from committing or causing any violations of certain
provisions of the Investment Advisers Act of 1940, the Investment Company Act of
1940, and various Minnesota laws. AEFC agreed to pay disgorgement of $10 million
and civil money penalties of $7 million. AEFC also agreed to retain an
independent distribution consultant to assist in developing a plan for
distribution of all disgorgement and civil penalties ordered by the SEC in
accordance with various undertakings detailed at
http://www.sec.gov/litigation/admin/ia-2451.pdf. Ameriprise Financial and its
affiliates have cooperated with the SEC and the MDOC in these legal proceedings,
and have made regular reports to the RiverSource Funds' Boards of
Directors/Trustees.

On November 7, 2008, RiverSource Investments, LLC, a subsidiary of Ameriprise
Financial, Inc., acquired J. & W. Seligman & Co. Incorporated (Seligman). In
late 2003, Seligman conducted an extensive internal review concerning mutual
fund trading practices. Seligman's review, which covered the

- --------------------------------------------------------------------------------
44  RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT



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



period 2001-2003, noted one arrangement that permitted frequent trading in
certain open-end registered investment companies managed by Seligman (the
Seligman Funds); this arrangement was in the process of being closed down by
Seligman before September 2003. Seligman identified three other arrangements
that permitted frequent trading, all of which had been terminated by September
2002. In January 2004, Seligman, on a voluntary basis, publicly disclosed these
four arrangements to its clients and to shareholders of the Seligman Funds.
Seligman also provided information concerning mutual fund trading practices to
the SEC and the Office of the Attorney General of the State of New York (NYAG).

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc. (now known as RiverSource Fund
Distributors, Inc.), Seligman Data Corp. and Brian T. Zino (collectively, the
Seligman Parties), alleging, in substance, that the Seligman Parties permitted
various persons to engage in frequent trading and, as a result, the prospectus
disclosure used by the registered investment companies then managed by Seligman
was and had been misleading. The NYAG included other related claims and also
claimed that the fees charged by Seligman to the Seligman Funds were excessive.
On March 13, 2009, without admitting or denying any violations of law or
wrongdoing, the Seligman Parties entered into a stipulation of settlement with
the NYAG and settled the claims made by the NYAG. Under the terms of the
settlement, Seligman paid $11.3 million to four Seligman Funds. This settlement
resolved all outstanding matters between the Seligman Parties and the NYAG. In
addition to the foregoing matter, the New York staff of the SEC indicated in
September 2005 that it was considering recommending to the Commissioners of the
SEC the instituting of a formal action against Seligman and Seligman Advisors,
Inc. relating to frequent trading in the Seligman Funds. Seligman responded to
the staff in October 2005 that it believed that any action would be both
inappropriate and unnecessary, especially in light of the fact that Seligman had
previously resolved the underlying issue with the Independent Directors of the
Seligman Funds and made recompense to the affected Seligman Funds. There have
been no further developments with the SEC on this matter.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings, including
routine litigation, class actions, and governmental actions, concerning matters
arising in connection with the conduct of their business activities. Ameriprise
Financial believes that the Funds are not currently the subject of, and that
neither Ameriprise Financial nor any of its affiliates are the subject of, any
pending legal, arbitration or regulatory proceedings that are likely to have a
material

- --------------------------------------------------------------------------------
      RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2010 SEMIANNUAL REPORT  45



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


adverse effect on the Funds or the ability of Ameriprise Financial or its
affiliates to perform under their contracts with the Funds. Ameriprise Financial
is required to make 10-Q, 10-K and, as necessary, 8-K filings with the
Securities and Exchange Commission on legal and regulatory matters that relate
to Ameriprise Financial and its affiliates. Copies of these filings may be
obtained by accessing the SEC website at www.sec.gov.

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse effect
on the Funds or the ability of Ameriprise Financial or its affiliates to perform
under their contracts with the Funds, these proceedings are subject to
uncertainties and, as such, we are unable to estimate the possible loss or range
of loss that may result. An adverse outcome in one or more of these proceedings
could result in adverse judgments, settlements, fines, penalties or other relief
that could have a material adverse effect on the consolidated financial
condition or results of operations of Ameriprise Financial.
