 6 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, portfolio managers Dimitris Bertsimas, Gina Mourtzinou and Steve Kokkotos
discuss RiverSource Disciplined Small and Mid Cap Equity Fund's positioning and
results for the 12-month period ended July 31, 2007.

At July 31, 2007, approximately 34% of the Fund's shares were owned in the
aggregate by affiliated funds-of-funds managed by RiverSource Investments, LLC
(RiverSource). As a result of asset allocation decisions by RiverSource, it is
possible that RiverSource Disciplined Small and Mid Cap Equity Fund may
experience relatively large purchases or redemptions from affiliated
funds-of-funds (see page 36, Class I capital share transactions for related
activity during the most recent fiscal period). RiverSource seeks to minimize
the impact of these transactions by structuring them over a reasonable period of
time. RiverSource Disciplined Small and Mid Cap Equity Fund may experience
increased expenses as it buys and sells securities as a result of purchases or
redemptions by affiliated funds-of-funds. For more information of the Fund's
expenses, see the discussions beginning on pages 14 and 33.

Q: How did RiverSource Disciplined Small and Mid Cap Equity Fund perform for the
   annual period?

A: RiverSource Disciplined Small and Mid Cap Equity Fund's Class A shares
   (excluding sales charge) returned 7.12% for the 12-month period ended July
   31, 2007. The Fund underperformed its benchmark, the Russell 2500(TM) Index
   (Russell Index), which returned 15.55%, as well as the Lipper Mid-Cap Core
   Funds Index, representing the Fund's peer group, which returned 18.28%, for
   the same period.

   DURING THE REPORTING PERIOD, ALL THREE QUANTITATIVE INVESTMENT MODELS
   UNDERPERFORMED THE RUSSELL INDEX.


Q: What factors most significantly affected the Fund's performance?

A: The Fund's underperformance resulted from the three quantitative investment
   models -- momentum, value and quality-adjusted value -- we employ in
   selecting stocks for the Fund's portfolio. The momentum model singles out
   groups of companies that appear to be having improving prospects based on the
   pattern of stock returns observed over history. The value model selects
   undervalued stocks based on proprietary estimates of future corporate
   earnings. The quality-adjusted value model selects undervalued securities by
   adjusting the valuations of stocks to take into account each stock's
   historical earnings

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

  RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  7

QUESTIONS & ANSWERS

   stability and debt load. Under the Fund's investment process, the three
   models choose the small- and mid-cap stocks for the portfolio. We then weight
   the models and determine the exposure to sectors and industries.

   During the reporting period, all three quantitative investment models
   underperformed the Russell Index. The quality-adjusted value model performed
   worst, followed by value and then momentum. While the Fund may experience
   underperformance in the short term, our research has indicated that the style
   diversification provided by the three very different quantitative models is a
   significant investment advantage, which may lead to long-term outperformance.

   The Fund's greater-than-Russell Index positions in energy and materials and
   its lesser-than-Russell Index allocation to utilities contributed most
   positively to its results relative to the Russell Index for the annual
   period. To a more moderate degree, the Fund's significant exposure to the
   consumer discretionary and consumer staples sectors and its modest position
   in health care also helped. Moving from a sizable exposure to financials to a
   modest position in the sector over the period proved prudent as well. From a
   sector allocation perspective, the only detractors were the Fund's modest
   exposure to the strongly-performing information technology and industrials
   sectors.

   Because of our investment process, most of the Fund's underperformance was
   the result of stock selection. In the telecommunication services and consumer
   staples sectors, stock selection helped performance. However, these positives
   were not enough to offset our selections within financials, consumer
   discretionary, industrials and health care, which detracted from Fund
   performance. Among individual holdings, the stocks that detracted most from
   the Fund's results were in the financials sectors. These included American
   Home Mtge Investment (selected by the value and quality-adjusted value
   models), W Holding (value and quality-adjusted value models), Radian Group
   (value and quality-adjusted value models), PMI Group (quality-adjusted value
   and value models) and People's United Financial (momentum model).

   On the positive side, stocks that contributed favorably to the Fund's return
   included financial commercial services and supply company Deluxe (selected by
   the value model), materials companies CF Industries Holdings (value and
   quality-adjusted value models) and Quanex (quality-adjusted value and value

   models) and food and staples retailer Supervalu (quality-adjusted value and
   value models).

   At the end of July, the Fund's largest individual stock holdings included
   several financial companies, including PMI Group, First American (selected by
   quality-adjusted value and value models), Fidelity National Financial
   (quality-adjusted value and value models) and Radian Group. Another top
   holding at the end of the period was information technology company Avnet
   (all three models).

   In managing risk associated with small- and mid-cap investing, we use a
   proprietary risk management system that allows us to manage the Fund's
   exposure to several key factors, including industry, sector, market
   capitalization and portfolio turnover. During the period, we used these and
   other techniques to reduce the expected risk of the portfolio and to avoid
   large deviations from the Index.

Q: What changes did you make to the Fund's portfolio during the period?

A: Based on an extensive look we took at our quantitative models, in March 2007,
   we expanded and improved the valuation measures we use in our value model.
   Also, because diversification is an effective element of risk management, we
   increased the number of holdings in the portfolio over the annual period from
   310 to 400. Finally, as a result of quantitative models-driven stock
   selection during the period, the portfolio's sector allocations changed
   somewhat. For example, as indicated, the Fund's exposure to financials
   relative to the Russell Index decreased. Conversely, the Fund's relative
   position in energy increased. Overall portfolio turnover was 84% for the 12
   months.

   WE BELIEVE OUR USE OF MULTIPLE INVESTMENT DISCIPLINES SERVES THE FUND WELL
   IN ALL INVESTMENT ENVIRONMENTS OVER THE LONG TERM, AND THE DIVERSIFIED
   PORTFOLIO MAY BE WELL POSITIONED FOR ANY POTENTIAL MARKET CONDITIONS.


Q: How do you intend to manage the Fund in the coming months?

A: We believe our use of multiple investment disciplines serves the Fund well in
   all investment environments over the long term, and the diversified portfolio
   is well positioned for any potential market conditions. Whether there is a
   surge in

QUESTIONS & ANSWERS

   small- and mid-cap stocks or a downturn, the combination of models should, in
   our view, help us deliver value relative to the Russell Index over extended
   periods of time. We are equally convinced of the merit of our multifaceted,
   disciplined approach to managing risk in the portfolio. We believe this
   combination of style diversification and rigorous risk control will allow us
   to maintain the high quality of the Fund's portfolio in whatever market
   conditions lie ahead.

Funds Index. In comparing the Fund's Class A shares to these indices, you should
take into account the fact that the Fund's performance reflects the maximum
sales charge of 5.75%, while such charges are not reflected in the performance
of the indices. Returns for the Fund include the reinvestment of any
distribution paid during each period.

The performance information shown represents past performance and is not a
guarantee of future results. The table below and the chart on the facing page do
not reflect the deduction of taxes that a shareholder would pay on fund
distributions or the redemption of fund shares. 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 institution or visiting riversource.com/funds. Also
see "Past Performance" in the Fund's current prospectus.

 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  13


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 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). The
Fund's indirect expense from investing in the acquired funds is based on the
Fund's pro rata portion of the cumulative expenses charged by the acquired funds
using the acquired funds expense ratio as of the 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 ended July 31, 2007.

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 "Expenses paid during the period" to estimate the
expenses you paid on your account during this 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.

</Table>

 *   Effective Dec. 11, 2006, Class Y was renamed Class R4.
(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended July 31, 2007: -6.46%
     for Class A, -6.79% for Class B, -6.79% for Class C, -6.36% for Class I,
     -6.37% for Class R4 and -6.47% for Class W.
(c)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until July 31, 2008,
     unless sooner terminated at the discretion of the Fund's Board, such that
     net expenses, (excluding fees and expenses of acquired funds) before giving
     effect to any performance incentive adjustment, will not exceed 1.36% for
     Class A, 2.12% for Class B, 2.12% for Class C, 0.96% for Class I, 1.23% for
     Class R4 and 1.41% for Class W. Any amounts waived will not be reimbursed
     by the Fund. This change was effective Aug. 1, 2007. If this change had
     been in place for the entire six month period ended July 31, 2007, the
     actual expenses paid would have been $9.92 for Class B, $9.92 for Class C,
     $4.37 for Class I, $5.67 for Class R4 and $6.57 for Class W; the
     hypothetical expenses paid would have been $10.34 for Class B, $10.34 for
     Class C, $4.56 for Class I, $5.91 for Class R4 and $6.85 for Class W; the
     actual and hypothetical expenses paid for Class A would have been the same
     as those expenses in the table above.

 28 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT


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 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.

The Fund's significant accounting policies are summarized below:

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 each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds 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 equities) 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 New York Stock Exchange 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 New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, 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
New York Stock Exchange. Swap transactions are valued through an authorized
pricing service, broker, or an internal model. 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; those maturing in 60
days or less are valued at amortized cost.

 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  29


OPTION TRANSACTIONS

To produce incremental earnings, protect gains, and facilitate buying and
selling of securities for investments, the Fund may buy and write options traded
on any U.S. or foreign exchange or in the over-the-counter market where
completing the obligation depends upon the credit standing of the other party.
Cash collateral may be collected by the Fund to secure certain over-the-counter
options trades. Cash collateral held by the Fund for such option trades must be
returned to the counterparty upon closure, exercise or expiration of the
contract. The Fund also may buy and sell put and call options and write covered
call options on portfolio securities as well as write cash-secured put options.
The risk in writing a call option is that the Fund gives up the opportunity for
profit if the market price of the security increases. The risk in writing a put
option is that the Fund may incur a loss if the market price of the security
decreases and the option is exercised. The risk in buying an option is that the
Fund pays a premium whether or not the option is exercised. The Fund also has
the additional risk of being unable to enter into a closing transaction if a
liquid secondary market does not exist.

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid. At
July 31, 2007, the Fund had no outstanding option contracts.

FUTURES TRANSACTIONS

To gain exposure to or protect itself from market changes, the Fund may buy and
sell financial futures contracts traded on any U.S. or foreign exchange. The
Fund also may buy and write put and call options on these futures contracts.
Risks of entering into futures contracts and related options include 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.

Futures are valued daily based upon the last sale price at the close of 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.

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase

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

 30 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT


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.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations. At July 31, 2007, the
Fund had no outstanding forward foreign currency contracts.

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 to shareholders. No provision for income or excise
taxes is thus required.

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of deferred losses on
certain futures contracts, the recognition of certain foreign currency gains
(losses) as ordinary income (loss) for tax purposes, and losses deferred due to
"wash sale" transactions. 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.

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been decreased by $19,501
and accumulated net realized loss has been decreased by $19,501.

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value, and requires additional disclosures
about fair-value measurements. The application of SFAS 157 is required for
fiscal years

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

 32 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT


beginning after Nov. 15, 2007 and interim periods within those fiscal years. The
impact of SFAS 157 on the Fund's financial statements is being evaluated.

In June 2006, the FASB issued FASB Interpretation 48 (FIN 48), "Accounting for
Uncertainty in Income Taxes." FIN 48 clarifies the accounting for uncertainty in
income taxes recognized in accordance with FASB Statement 109, "Accounting for
Income Taxes." FIN 48 prescribes a two-step process to recognize and measure a
tax position taken or expected to be taken in a tax return. The first step is to
determine whether a tax position has met the more-likely-than-not recognition
threshold and the second step is to measure a tax position that meets the
threshold to determine the amount of benefit to recognize. FIN 48 also provides
guidance on derecognition, classification, interest and penalties, accounting in
interim periods, disclosure, and transition. FIN 48 is effective for fiscal
years beginning after Dec. 15, 2006. Tax positions of the Fund are being
evaluated to determine the impact, if any, to the Fund. The adoption of FIN 48
is not anticipated to have a material impact on the Fund.

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.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Fund's average daily net assets that declines from 0.70%
to 0.475% annually as the Fund's assets increase. The fee may be adjusted upward
or downward by a performance incentive adjustment based on a comparison of the
performance of Class A shares of the Fund to 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 fee by
$17,062 for the year ended July 31, 2007. The management fee for the year ended
July 31, 2007, was 0.66% of the Fund's average daily net assets, including an
adjustment under the terms of the performance incentive adjustment.

Under an Administrative Services Agreement, the Fund pays Ameriprise Financial a
fee for administration and accounting services at a percentage of the Fund's

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

 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  33


average daily net assets that declines from 0.06% to 0.03% annually as the
Fund's assets increase.

Other expenses in the amount of $863 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 Funds and the Board.

Compensation of Board members includes, for a former Board Chair, compensation
as well as retirement benefits. Certain other aspects of a former Board Chair's
compensation, including health benefits and payment of certain other expenses,
are included under other expenses.

Under a Deferred Compensation Plan (the Plan), non-interested board members 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
RiverSource funds. The Fund's liability for these amounts is adjusted for market
value changes and remains in the Fund until distributed in accordance with the
Plan.

Professional fees include fees include fees paid by the Fund for legal services
and independent registered public accounting firm services.

Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains shareholder accounts and records. The Fund pays the Transfer
Agent an annual fee per shareholder account for this service as follows:

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
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. Prior to Dec.
11, 2006, the Fund paid the Transfer Agent an annual account-based fee of $17.50
per shareholder account.

In addition, the Fund pays the Transfer Agent an annual asset-based fee at a
rate of 0.20% of the Fund's average daily net assets attributable to Class W
shares.

Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate per
shareholder account of $1. Effective Dec. 11, 2006, this fee was eliminated.

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

 34 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT


The Transfer Agent charges an annual fee of $5 per inactive account, charged on
a pro rata basis for 12 months from the date the account becomes inactive. These
fees are included in the transfer agency fees on the statement of operations.

The Fund has agreements with Ameriprise Financial Services, Inc. and RiverSource
Distributors, Inc. (collectively, 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.

Effective Dec. 11, 2006, a Plan Administration Services Agreement was adopted
for the restructured Class R4. The fee is calculated at a rate of 0.25% of the
Fund's average daily net assets attributable to Class R4 shares.

Prior to Dec 11, 2006, under a Shareholder Service Agreement, the Fund paid the
Distributor a fee for service provided to shareholders by the Distributor and
other servicing agents with respect to Class Y shares. The fee was calculated at
a rate of 0.10% of the Fund's average daily net assets attributable to Class Y
shares. Effective Dec. 11, 2006, this agreement was terminated.

Sales charges received by the Distributor for distributing Fund shares were
$55,860 for Class A and $5 for Class C for the year ended July 31, 2007.

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.

For the year ended July 31, 2007, the Investment Manager and its affiliates
waived certain fees and expenses such that net expenses (excluding fees and
expenses of acquired funds), before giving effect to any performance incentive
adjustment, were 1.29% for Class A, 2.06 % for Class B, 2.06% for Class C, 1.15%
for Class R4 and 1.32% for Class W. Of these waived fees and expenses, the
transfer agency fees waived for Class R4 and Class W were $8 and $5,488,
respectively, and the management fees waived at the Fund level were $65,127.
Under an agreement, which was effective until July 31, 2007, the Investment
Manager and its affiliates contractually agreed to waive certain fees and
expenses, such that net expenses (excluding fees and expenses of acquired
funds), before giving effect to any performance incentive adjustment, would not
exceed 1.36% for Class A, 2.13% for Class B, 2.13% for Class C, 1.01% for Class
I, 1.19% for Class R4 and 1.36% for Class W of the Fund's average daily net
assets. Effective Aug. 1, 2007,

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

 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  35


the Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses such that net expenses (excluding fees and expenses of
acquired funds), before giving effect to any performance incentive adjustment,
will not exceed 1.36% for Class A, 2.12 % for Class B, 2.12% for Class C, 0.96%
for Class I, 1.23% for Class R4 and 1.41% for Class W of the Fund's average
daily net assets, until July 31, 2008, unless sooner terminated at the
discretion of the Board.

During the year ended July 31, 2007, the Fund's custodian and transfer agency
fees were reduced by $3,850 as a result of earnings and bank fee credits from
overnight cash balances. The Fund also pays custodian fees to Ameriprise Trust
Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $142,075,573 and $33,333,386, respectively, for the year
ended July 31, 2007. Realized gains and losses are determined on an identified
cost basis.

a money market fund established for the exclusive use of the RiverSource funds
and other institutional clients of RiverSource Investments. Cost of purchases
and proceeds from sales of securities aggregated $80,827,100 and $79,067,313,
respectively, for the year ended July 31, 2007.

7. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The agreement went into effect Sept. 19, 2006. The Fund must maintain asset
coverage for borrowings of at least 300%. The agreement, which enables the Fund
to participate with other RiverSource funds, permits borrowings up to $500
million, collectively. Interest is charged to each Fund based on its borrowings
at a rate equal to either the higher of the Federal Funds Effective Rate plus
0.40% or the JPMCB Prime Commercial Lending Rate. Borrowings are payable within
60 days after such loan is executed. The Fund also pays a commitment fee equal
to its pro rata share of the amount of the credit facility at a rate of 0.06%
per annum. Prior to this agreement, the Fund paid a commitment fee equal to its
pro rata share of the amount of the credit facility at a rate of 0.07% per
annum. The Fund had no borrowings under the facility outstanding during the year
ended July 31, 2007.

8. CAPITAL LOSS CARRY-OVER AND POST-OCTOBER LOSS

The Fund also had a post-October loss of $6,598 at July 31, 2007.

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.

9. 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 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. In response to defendants' motion to dismiss the
complaint, the 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 may file a notice of appeal with the Eighth Circuit Court of Appeals
within 30 days from the date of judgment.

In December 2005, without admitting or denying the allegations, American Express
Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc.
(Ameriprise Financial)), the parent company of RiverSource Investments, LLC
(RiverSource Investments), entered into settlement agreements with the
Securities and Exchange Commission (SEC) and Minnesota Department of Commerce
(MDOC) related to market timing activities. In connection with these matters,
the SEC and MDOC issued orders (the Orders) alleging that AEFC violated certain
provisions of the federal and Minnesota securities laws by failing to adequately
disclose market timing activities by allowing certain identified market timers
to continue to market time contrary to disclosures in mutual fund and variable
annuity product prospectuses. The Orders also alleged that AEFC failed to
implement procedures to detect and prevent market timing in 401(k) plans for
employees of AEFC and related companies and failed to adequately disclose that
there were no such procedures. Pursuant to the MDOC Order, the MDOC also alleged
that AEFC allowed inappropriate market timing to occur by failing to have
written policies and procedures and failing to properly supervise its employees.

As a result of the Orders, 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. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and

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

whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. 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. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

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.

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.

     in the above reported expense ratios.
(f)  The Investment Manager and its affiliates waived/reimbursed the Fund for

(i)  Not annualized.

 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  45


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF RIVERSOURCE

DISCIPLINED SMALL AND MID CAP EQUITY FUND:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities, of RiverSource Disciplined Small and
Mid Cap Equity Fund (the Fund), one of the portfolios constituting the
RiverSource Dimensions Series, Inc. as of July 31, 2007, and the related
statement of operations, statement of changes in net assets and financial
highlights for the year then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audit. The financial statements and financial highlights of the
Fund for the periods presented through July 31, 2006, were audited by other
auditors whose report dated September 20, 2006, expressed an unqualified opinion
on those financial statements and financial highlights.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audit included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of July 31, 2007, by correspondence with the custodian and
brokers, or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audit provides a reasonable basis for our
opinion.

In our opinion, the 2007 financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
RiverSource Disciplined Small and Mid Cap Equity Fund of the RiverSource
Dimensions Series, Inc. at July 31, 2007, the results of its operations, the
changes in its net assets and the financial highlights for the year then ended,
in conformity with U.S. generally accepted accounting principles.

 52 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT


APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

RiverSource Investments, LLC ("RiverSource"), a wholly-owned subsidiary of
Ameriprise Financial, Inc. ("Ameriprise Financial"), serves as the investment
manager to the Fund. Under an investment management services agreement (the "IMS
Agreement") RiverSource provides investment advice and other services to the
Fund and all RiverSource funds (collectively, the "Funds"). The Fund's Board of
Directors (the "Board") and the Board's Investment Review and Contracts
Committees monitor these services throughout the year.

On an annual basis, the Board, including the independent Board members (the
"Independent Directors"), considers renewal of the IMS Agreement. RiverSource
prepares detailed reports for the Board and its Contracts Committee in March and
April, including reports based on data provided by independent organizations to
assist the Board in making this determination. In addition, throughout the year,
the Board (or its committees) reviews information prepared by RiverSource
addressing the services RiverSource provides and Fund performance. The Board
accords particular weight to the work, deliberations and conclusions of the
Contracts and Investment Review Committees in determining whether to continue
the IMS Agreement. At the April 11-12, 2007 in-person Board meeting, independent
legal counsel to the Independent Directors reviewed with the Independent
Directors various factors relevant to the Board's consideration of advisory
agreements and the Board's legal responsibilities related to such consideration.
Following an analysis and discussion of the factors identified below, the Board,
including all of the Independent Directors, approved renewal of the IMS
Agreement.

Nature, Extent and Quality of Services Provided by RiverSource:  The Board
analyzed various reports and presentations it had received detailing the
services performed by RiverSource, as well as its expertise, resources and
capabilities. The Board specifically considered many developments during the
past year concerning the services provided by RiverSource, including, in
particular, the growing strength and capabilities of many RiverSource offices
and the increased investment and resources dedicated to the Fund's operations,
particularly in the areas of trading systems, legal and compliance. Further, in
connection with the Board's evaluation of the overall package of services
provided by RiverSource, the Board considered the quality of the administrative,
custody and transfer agency services provided by RiverSource affiliates to the
Fund. The Board also reviewed the financial condition of RiverSource and the
entity's ability to carry out its responsibilities under the IMS Agreement. The
Board also discussed the acceptability of the terms of the IMS Agreement
(including the relatively broad scope of services required to be performed by
RiverSource). The Board concluded that the services being performed under the
IMS Agreement were of a reasonably high quality.

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

 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  53


Based on the foregoing, and based on other information received (both oral and
written, including the information on investment performance referenced below)
and other considerations, the Board determined that RiverSource was in a
position to continue to provide a high quality and level of services to the
Fund.

Investment Performance:  The Board observed that the Fund launched in May 2006.
For purposes of evaluating the nature, extent and quality of services provided
under the IMS Agreement, the Board carefully reviewed the investment performance
of the Fund. In this regard, the Board considered: (i) detailed reports
containing data prepared by an independent organization showing, for various
periods, the performance of the Fund, the performance of a benchmark index, the
percentage ranking of the Fund among its comparison group and the net assets of
the Fund; and (ii) a report detailing the Fund's performance over various
periods (including since inception) and recent Fund inflows (and outflows). The
Board observed that the Fund's investments reflected the interrelationship of
particular market conditions with the specific management style employed by the
portfolio management team.

Comparative Fees, Costs of Services Provided and the Profits Realized By
RiverSource and its Affiliates from their Relationships with the Fund:  The
Board reviewed comparative fees and the costs of services to be provided under
the IMS Agreement. The Board members considered detailed comparative information
set forth in an annual report on fees and expenses, including, among other
things, data (prepared by an independent organization) showing a comparison of
the Fund's expenses with median expenses paid by funds in its peer group, as
well as data showing the Fund's contribution to RiverSource's profitability. The
Board accorded particular weight to the notion that the level of fees should
reflect a rational pricing model applied consistently across the various product
lines in the Funds' family, while assuring that the overall fees for each fund
are generally in line with the "pricing philosophy" (i.e., that the total
expense ratio of each fund, with few exceptions, is at or below the median
expense ratio of funds in the same comparison group). The Board took into
account that the Fund's total expense ratio (after considering proposed expense
caps/waivers) was below the peer group's median expense ratio shown in the
reports. Based on its review, the Board concluded that the Fund's management fee
was fair and reasonable in light of the extent and quality of services that the
Fund receives.

The Board also considered the expected profitability of RiverSource and its
affiliates in connection with RiverSource providing investment management
services to the Fund. In this regard, the Board referred to a detailed
profitability report, discussing the profitability to RiverSource and Ameriprise
Financial from managing and operating the Fund, including data showing
comparative profitability. The Board also considered the services acquired by
the investment manager through the use of commission dollars paid by the Funds
on portfolio transactions. The Board noted that the fees paid by the Fund should
permit the

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

 54 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT


investment manager to offer competitive compensation to its personnel, make
necessary investments in its business and earn an appropriate profit. The Board
concluded that profitability levels were reasonable.

Economies of Scale to be Realized:  The Board also considered the economies of
scale that might be realized by RiverSource as the Fund grows and took note of
the extent to which Fund shareholders might also benefit from such growth. The
Board considered that the IMS Agreement provides for lower fees as assets
increase at pre-established breakpoints and concluded that the IMS Agreement
satisfactorily provided for sharing these economies of scale.

Based on the foregoing, the Board, including all of the Independent Directors,
concluded that the investment management service fees were fair and reasonable
in light of the extent and quality of services provided. In reaching this
conclusion, no single factor was determinative. On April 12, 2007, the Board,
including all of the Independent Directors, approved the renewal of the IMS
Agreement.

PROXY VOTING

The policy of the Board is to vote the proxies of the companies in which the
Fund holds investments consistent with the procedures as stated in the Statement
of Additional Information (SAI). You may obtain a copy of the SAI without charge
by calling RiverSource Funds at (888) 791-3380; contacting your financial
institution; visiting riversource.com/funds; or searching the website of the
Securities and Exchange Commission (SEC) at http://www.sec.gov. Information
regarding how the Fund voted proxies relating to portfolio securities is filed
with the SEC by August 31 for the most recent 12-month period ending June 30 of
that year, and is available without charge by visiting riversource.com/funds; or
searching the website of the SEC at www.sec.gov.

CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

On April 12, 2007, Ernst & Young LLP was selected as the Fund's independent
registered public accounting firm for the 2007 fiscal year. A majority of the
Fund's Board of Directors, including a majority of the Independent Directors,
approved the appointment of Ernst & Young LLP. The predecessor independent
registered public accounting firm's reports on the Fund's financial statements
for the year ended July 31, 2006 and the year ended July 31, 2005 contained no
adverse opinion or disclaimer of opinion and were not qualified or modified as
to uncertainty, audit scope or accounting principles. During such fiscal periods
and through April 12, 2007 there were no disagreements between the Fund and the
predecessor independent registered public accounting firm on any matter of

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

 RIVERSOURCE DISCIPLINED SMALL AND MID CAP EQUITY FUND -- 2007 ANNUAL REPORT  55


accounting principles or practices, financial statement disclosure, or auditing
scope or procedures, which such disagreements, if not resolved to the
satisfaction of the predecessor independent registered public accounting firm,
would have caused them to make reference to the subject matter of the
disagreement in connection with their reports on the financial statements for
such fiscal periods.

QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, portfolio managers Dimitris Bertsimas, Gina Mourtzinou and Steve Kokkotos
discuss RiverSource Disciplined Small Cap Value Fund's positioning and results
for the 12-month period ended July 31, 2007.

At July 31, 2007, approximately 64% of the Fund's shares were owned in the
aggregate by affiliated funds-of-funds managed by RiverSource Investments, LLC
(RiverSource). As a result of asset allocation decisions by RiverSource, it is
possible that RiverSource Disciplined Small Cap Value Fund may experience
relatively large purchases or redemptions from affiliated funds-of-funds (see
page 39, Class I capital share transactions for related activity during the most
recent fiscal period). RiverSource seeks to minimize the impact of these
transactions by structuring them over a reasonable period of time. RiverSource
Disciplined Small Cap Value Fund may experience increased expenses as it buys
and sells securities as a result of purchases or redemptions by affiliated
funds-of-funds. For more information of the Fund's expenses, see the discussions
beginning on pages 14 and 36.

Q: How did RiverSource Disciplined Small Cap Value Fund perform for the annual
   period?

A: RiverSource Disciplined Small Cap Value Fund's Class A shares (excluding
   sales charge) returned 4.29% for the 12-month period ended July 31, 2007. The
   Fund underperformed its benchmark, the unmanaged Russell 2000(R) Value Index
   (Russell Index), which gained 7.67%, as well as the Lipper Small-Cap Value
   Funds Index, representing the Fund's peer group, which returned 13.52%, for
   the same period.

   BECAUSE OF OUR INVESTMENT PROCESS, MOST OF THE FUND'S UNDERPERFORMANCE
   RESULTED FROM STOCK SELECTION.


Q: What factors most significantly affected the Fund's performance?

A: The Fund's performance resulted from the three quantitative investment
   models -- momentum, value and quality -- we employ in selecting stocks for
   the Fund's portfolio. The momentum model identifies stocks we believe will
   experience improved investor sentiment over the next six to nine months. The
   value model uses a proprietary earnings estimate and selects stocks with low
   price-to-predicted-earnings ratios. The quality model selects companies that
   we believe possess strong and stable fundamentals, adjusted for value.

   Under the Fund's investment process, the three models choose the small-cap
   value stocks for the portfolio. We then weight the models and determine the

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

 8 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT

QUESTIONS & ANSWERS

   exposure to sectors and industries. During the reporting period, the momentum
   model outperformed the Russell Index, but the quality model underperformed.
   The value model also underperformed through March 2007, when we expanded the
   valuation measures we use within the model. Subsequently, the value model
   outperformed the Russell Index, but it was not enough to offset the
   detracting effect of its underperformance earlier in the fiscal year. While
   the Fund may experience underperformance in the short term, our research has
   shown that the style diversification provided by the three very different
   quantitative models is an investment advantage, which may lead to long-term
   outperformance.

   During the period, the Fund's greater-than-Russell Index positions in
   consumer discretionary, materials, consumer staples, industrials and
   telecommunication services and its lesser-than-Russell Index allocations to
   health care, energy, financials and utilities all contributed positively to
   its results relative to the Russell Index. From a sector allocation
   perspective, the only detractor was the Fund's modest exposure to the
   strongly performing information technology sector.

   Because of our investment process, most of the Fund's underperformance
   resulted from stock selection, which helped performance in the materials,
   telecommunication services and industrials sectors. However, these positives
   were not enough to outweigh our selections within financials, consumer
   discretionary and information technology, which detracted from Fund
   performance.

   Some stocks that contributed favorably to the Fund's return included
   financial commercial services and supply company Deluxe (selected by the
   value model), telecommunication services company Cogent Communications
   (momentum model), insurance company Ohio Casualty (quality and revised value
   model) and materials company Terra Industries (momentum model).

   Among individual holdings, the stocks that detracted most from the Fund's
   results were in the financials sector. These included New Century Financial
   (selected by all three models but then sold in March when we revised the
   value model), American Home Mtge Investment (value and quality models), W
   Holding (value and quality models), Fremont General (value and quality
   models) and Accredited Home Lenders (value model).

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

           RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  9

QUESTIONS & ANSWERS

   At the end of July, the Fund's largest individual stock holdings included
   three insurance companies: Ohio Casualty, Aspen Insurance Holdings (selected
   by value and quality models) and LandAmerica Financial Group (all three
   models). Other top holdings at the end of the period were commercial bank
   First BanCorp (value and quality models) and metals and mining company Quanex
   (all three models).

   In managing risk associated with small-cap investing, we use a proprietary
   risk management system that allows us to manage the Fund's exposure to
   several key factors, including industry, sector, market capitalization and
   portfolio turnover. During the period, we used these and other techniques to
   reduce the expected risk of the portfolio and to avoid large deviations from
   the Russell Index.

Q: What changes did you make to the Fund's portfolio during the period?

A: Based on an extensive look we took at our quantitative models, in March 2007,
   we expanded and improved the measures we use in our value model. Also,
   because diversification is an effective element of risk management, we
   increased the number of holdings in the portfolio during the annual period
   from 250 to 351. Finally, as a result of quantitative models-driven stock
   selection during the period, the portfolio's sector allocations changed
   somewhat. For example, the Fund's exposure to energy relative to the Russell
   Index increased, while its position in financials decreased. Overall
   portfolio turnover was 127% for the 12 months.

   BASED ON AN EXTENSIVE LOOK WE TOOK AT OUR QUANTITATIVE MODELS, IN MARCH
   2007, WE EXPANDED AND IMPROVED THE MEASURES WE USE IN OUR VALUE MODEL.

 10 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT

QUESTIONS & ANSWERS

Q: How do you intend to manage the Fund in the coming months?

A: We believe our use of multiple investment disciplines serves the Fund well in
   all investment environments over the long term, and the portfolio may be well
   positioned for any potential market condition. Whether there is a surge in
   small-cap stocks or a downturn, the combination of models should, in our
   view, help us deliver value relative to the Russell Index over extended
   periods of time. We are equally convinced that our multifaceted, disciplined
   approach may assist in controlling risk in the portfolio. We believe this
   combination of style diversification and rigorous risk management will allow
   us to maintain the high quality of the Fund's portfolio in whatever market
   conditions lie ahead.

THE FUND'S LONG-TERM PERFORMANCE

The chart on the facing page illustrates the total value of an assumed $10,000
investment in RiverSource Disciplined Small Cap Value Fund Class A shares (from
3/1/06 to 7/31/07)* as compared to the performance of two widely cited
performance indices, the Russell 2000 Value Index and the Lipper Small-Cap Value
Funds Index. In comparing the Fund's Class A shares to these indices, you should
take into account the fact that the Fund's performance reflects the maximum
sales charge of 5.75%, while such charges are not reflected in the performance
of the indices. Returns for the Fund include the reinvestment of any
distribution paid during each period.

The performance information shown represents past performance and is not a
guarantee of future results. The table below and the chart on the facing page do
not reflect the deduction of taxes that a shareholder would pay on fund
distributions or the redemption of fund shares. 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 institution or visiting riversource.com/funds. Also

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 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). The
Fund's indirect expense from investing in the acquired funds is based on the
Fund's pro rata portion of the cumulative expenses charged by the acquired funds
using the acquired funds expense ratio as of the 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 ended July 31, 2007.

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 "Expenses paid during the period" to estimate the
expenses you paid on your account during this 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.

*    Effective Dec. 11, 2006, Class Y was renamed Class R4.
(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended July 31, 2007: -9.01%
     for Class A, -9.34% for Class B, -9.34% for Class C, -8.82% for Class I,
     -9.20% for Class R2, -9.10% for Class R3, -9.01% for Class R4 and -8.83%.
     for Class R5.
(c)  The investment manager and its affiliates have contractually agreed to
     waive certain fees and to absorb certain expenses until July 31, 2008,
     unless sooner terminated at the discretion of the Fund's Board, such that
     net expenses, (excluding fees and expenses of acquired funds) before giving
     effect to any performance incentive adjustment, will not exceed 1.40% for
     Class A, 2.16% for Class B, 2.15% for Class C, 1.02% for Class I, 1.82% for
     Class R2, 1.57% for Class R3, 1.32% for Class R4 and 1.07% for Class R5.
     Any amounts waived will not be reimbursed by the Fund. This change was
     effective Aug. 1, 2007. If this change had been in place for the entire six
     month period ended July 31, 2007, the actual expenses paid would have been
     $6.33 for Class A, $9.91 for Class B, $9.87 for Class C, $4.55 for Class I,
     $8.32 for R2, $7.14 for Class R3, $5.96 for Class R4 and $4.78 for Class
     R5; the hypothetical expenses paid would have been $6.69 for Class A,
     $10.47 for Class B, $10.43 for Class C, $4.81 for Class I, $8.79 for R2,
     $7.54 for Class R3, $6.30 for Class R4 and $5.05 for Class R5.

 30 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Dimensions Series, Inc. and is registered
under the Investment Company Act of 1940 (as amended) as a diversified, open-
end management investment company. RiverSource Dimensions Series, Inc. has 10
billion authorized shares of capital stock that can be allocated among the
separate series as designated by 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. On Feb. 9, 2006, Ameriprise Financial, Inc. (Ameriprise
Financial), the parent company of Riversource Investments, LLC (the Investment
Manager) invested $10,010,640* in the Fund (996,000 shares for Class A, 1,000
shares for Class B, 1,000 shares for Class C, 2,064** shares for Class I and
1,000 shares for Class R4), which represented the initial capital for each class
at $10 per share. Shares of the Fund were first offered to the public on Feb.
16, 2006.

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

- -  Class A shares are sold with a front-end sales charge.

- -  Class B shares may be subject to a contingent deferred sales charge (CDSC)
   and automatically convert to Class A shares during the ninth year of
   ownership.

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

- -  Class I and Class R4 shares have no sales charge and are offered only to
   qualifying institutional investors.

Effective Dec. 11, 2006, the Board approved renaming Class Y as Class R4,
terminating the shareholder servicing agreement, revising the fee structure
under the transfer agent agreement from account-based to asset-based, and
adopting a plan administration services agreement.

At July 31, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
100% of Class I shares.

Effective Dec. 11, 2006, the Fund offers additional classes of shares, Class R2,
Class R3 and Class R5, to certain institutional investors. These shares are sold
without a front-end sales charge or CDSC. At July 31, 2007, Ameriprise Financial
owned 100% of Class R2, Class R3 and Class R5 shares.

At July 31, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 89% of the total outstanding Fund shares.

 * Includes $10,640 invested by the RiverSource Income Builder Funds.

** Includes 1,064 shares purchased by RiverSource Income Builder Funds.

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

          RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  31


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 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.

The Fund's significant accounting policies are summarized below:

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 each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds 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 equities) 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 New York Stock Exchange 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 New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, 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
New York Stock Exchange. Swap transactions are valued through an authorized
pricing service, broker, or an internal model. 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; those maturing in 60
days or less are valued at amortized cost.

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

 32 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT


OPTION TRANSACTIONS

To produce incremental earnings, protect gains, and facilitate buying and
selling of securities for investments, the Fund may buy and write options traded
on any U.S. or foreign exchange or in the over-the-counter market where
completing the obligation depends upon the credit standing of the other party.
Cash collateral may be collected by the Fund to secure certain over-the-counter
options trades. Cash collateral held by the Fund for such option trades must be
returned to the counterparty upon closure, exercise or expiration of the
contract. The Fund also may buy and sell put and call options and write covered
call options on portfolio securities as well as write cash-secured put options.
The risk in writing a call option is that the Fund gives up the opportunity for
profit if the market price of the security increases. The risk in writing a put
option is that the Fund may incur a loss if the market price of the security
decreases and the option is exercised. The risk in buying an option is that the
Fund pays a premium whether or not the option is exercised. The Fund also has
the additional risk of being unable to enter into a closing transaction if a
liquid secondary market does not exist.

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid. At
July 31, 2007, the Fund had no outstanding option contracts.

FUTURES TRANSACTIONS

To gain exposure to or protect itself from market changes, the Fund may buy and
sell financial futures contracts traded on any U.S. or foreign exchange. The
Fund also may buy and write put and call options on these futures contracts.
Risks of entering into futures contracts and related options include 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.

Futures are valued daily based upon the last sale price at the close of 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.

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS

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

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

          RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  33


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.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations. At July 31, 2007, the
Fund had no outstanding forward foreign currency contracts.

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 to shareholders. No provision for income or excise
taxes is thus required.

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of deferred losses on
certain futures contracts, the recognition of certain foreign currency gains
(losses) as ordinary income (loss) for tax purposes, and losses deferred due to
"wash sale" transactions. 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.

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been decreased by $14,205
and accumulated net realized gain has been increased by $14,205.

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out

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

          RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  35


a framework for measuring fair value, and requires additional disclosures about
fair-value measurements. The application of SFAS 157 is required for fiscal
years beginning after Nov. 15, 2007 and interim periods within those fiscal
years. The impact of SFAS 157 on the Fund's financial statements is being
evaluated.

In June 2006, the FASB issued FASB Interpretation 48 (FIN 48), "Accounting for
Uncertainty in Income Taxes." FIN 48 clarifies the accounting for uncertainty in
income taxes recognized in accordance with FASB Statement 109, "Accounting for
Income Taxes." FIN 48 prescribes a two-step process to recognize and measure a
tax position taken or expected to be taken in a tax return. The first step is to
determine whether a tax position has met the more-likely-than-not recognition
threshold and the second step is to measure a tax position that meets the
threshold to determine the amount of benefit to recognize. FIN 48 also provides
guidance on derecognition, classification, interest and penalties, accounting in
interim periods, disclosure, and transition. FIN 48 is effective for fiscal
years beginning after Dec. 15, 2006. Tax positions of the Fund are being
evaluated to determine the impact, if any to the Fund. The adoption of FIN 48 is
not anticipated to have a material impact on the Fund.

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.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Fund's average daily net assets that declines from 0.85%
to 0.725% annually as the Fund's assets increase. The fee may be adjusted upward
or downward by a performance incentive adjustment based on a comparison of the
performance of Class A shares of the Fund to 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 fee by
$13,668 for the year ended July 31, 2007. The management fee for the year ended
July 31, 2007, was 0.80% of the Fund's average daily net assets, including an
adjustment under the terms of the performance incentive arrangement.

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

 36 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT


Under an Administrative Services Agreement, the Fund pays Ameriprise Financial a
fee for administration and accounting services at a percentage of the Fund's
average daily net assets that declines from 0.08% to 0.05% annually as the
Fund's assets increase.

Other expenses in the amount of $509 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.

Compensation of Board members includes, for a former Board Chair, compensation
as well as retirement benefits. Certain other aspects of a former Board Chair's
compensation, including health benefits and payment of certain other expenses,
are included under other expenses.

Under a Deferred Compensation Plan (the Plan), non-interested board members 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
RiverSource funds. The Fund's liability for these amounts is adjusted for market
value changes and remains in the Fund until distributed in accordance with the
Plan.

Professional fees include fees paid by the Fund for legal services and
independent registered public accounting firm services.

Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains shareholder accounts and records. The Fund pays the Transfer
Agent an annual fee per shareholder account for this service as follows:

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
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. Prior to Dec.
11, 2006, the Fund paid the Transfer Agent an annual account-based fee of $17.50
per shareholder account.

In addition, the Fund 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 and Class R5 shares.

Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate per
shareholder account of $1. Effective Dec. 11, 2006, this fee was eliminated.

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

          RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  37


The Transfer Agent charges an annual fee of $5 per inactive account, charged on
a pro rata basis for 12 months from the date the account becomes inactive. These
fees are included in the transfer agency fees on the statement of operations.

The Fund has agreements with Ameriprise Financial Services, Inc. and RiverSource
Distributors, Inc. (collectively, 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.

Effective Dec. 11, 2006, a Plan Administration Services Agreement was adopted
for the restructured Class R4 and the introduction of Class R2 and Class R3. The
fee is calculated at a rate of 0.25% of the Fund's average daily net assets
attributable to Class R2, Class R3 and Class R4 shares.

Prior to Dec. 11, 2006, under a Shareholder Service Agreement, the Fund paid the
Distributor a fee for service provided to shareholders by the Distributor and
other servicing agents with respect to Class Y shares. The fee was calculated at
a rate of 0.10% of the Fund's average daily net assets attributable to Class Y
shares. Effective Dec. 11, 2006, this agreement was terminated.

Sales charges received by the Distributor for distributing Fund shares were
$15,072 for Class A, $523 for Class B and $49 for Class C for the year ended
July 31, 2007.

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.

For the year ended July 31, 2007, the Investment Manager and its affiliates
waived certain fees and expenses (excluding fees and expenses of acquired
funds), such that net expenses were 1.35% for Class A, 2.11% for Class B, 2.11%
for Class C, 1.05% for Class I, 1.80% for Class R2, 1.55% for Class R3, 1.26%
for Class R4 and 1.05% for Class R5. Of these waived fees and expenses, the
transfer agency fees waived for Class R2, Class R3, Class R4 and Class R5 were
$2, $1, $2 and $1, respectively, and the management fees waived at the Fund
level were $71,726. Under an agreement, which was effective until July 31, 2007,
the Investment Manager and its affiliates agreed to waived certain fees and
expenses such that net expenses (excluding fees and expenses of acquired funds),
before giving effect to

any performance incentive adjustment, would not exceed 1.48% for Class A, 2.25%
for Class B, 2.25% for Class C, 1.13% for Class I, 1.85% for Class R2, 1.60% for
Class R3, 1.31% for Class R4 and 1.10% for Class R5 of the Fund's average daily
net assets. Effective Aug. 1, 2007, the Investment Manager and its affiliates
have agreed to waive certain fees and expenses until July 31, 2008, unless
sooner terminated at the 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 1.40% for Class A, 2.16% for
Class B, 2.15% for Class C, 1.02% for Class I, 1.82% for Class R2, 1.57% for
Class R3, 1.32% for Class R4 and 1.07% for Class R5 of the Fund's average daily
net assets.

During the year ended July 31, 2007, the Fund's custodian and transfer agency
fees were reduced by $6,406 as a result of earnings and bank fee credits from
overnight cash balances. The Fund also pays custodian fees to Ameriprise Trust
Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $57,570,895 and $30,980,107, respectively, for the year

7. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The agreement went into effect Sept. 19, 2006. The Fund must maintain asset
coverage for borrowings of at least 300%. The agreement, which enables the Fund
to participate with other RiverSource funds, permits borrowings up to $500
million, collectively. Interest is charged to each Fund based on its borrowings
at a rate equal to either the higher of the Federal Funds Effective Rate plus
0.40% or the JPMCB Prime Commercial Lending Rate. Borrowings are payable within
60 days after such loan is executed. The Fund also pays a commitment fee equal
to its pro rata share of the amount of the credit facility at a rate of 0.06%
per annum. Prior to this agreement, the Fund paid a commitment fee equal to its
pro rata share of the amount of the credit facility at a rate of 0.07% per

8. 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 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. In response to defendants' motion to dismiss the
complaint, the 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 may file a notice of appeal with the Eighth Circuit Court of Appeals
within 30 days from the date of judgment.

In December 2005, without admitting or denying the allegations, American Express
Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc.
(Ameriprise Financial)), the parent company of RiverSource Investments, LLC
(RiverSource Investments), entered into settlement agreements with the
Securities and Exchange Commission (SEC) and Minnesota Department of Commerce
(MDOC) related to market timing activities. In connection with these matters,
the SEC and MDOC issued orders (the Orders) alleging that AEFC violated certain
provisions of the federal and Minnesota securities laws by failing to adequately
disclose market timing activities by allowing certain identified market timers
to continue to market time contrary to disclosures in mutual fund and variable
annuity product prospectuses. The Orders also alleged that AEFC failed to
implement procedures to detect and prevent market timing in 401(k) plans for
employees of AEFC and related companies and failed to adequately disclose that
there were no such procedures. Pursuant to the MDOC Order, the MDOC also alleged
that AEFC allowed inappropriate market timing to occur by failing to have
written policies and procedures and failing to properly supervise its employees.

As a result of the Orders, 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. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and

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

          RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  41


whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. 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. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

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.

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.

 50 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT


REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF

RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities of RiverSource Disciplined Small Cap
Value Fund (the Fund), one of the portfolios constituting the RiverSource
Dimensions Series, Inc, as of July 31, 2007, and the related statements of
operations, changes in net assets, and financial highlights for the year then
ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audit. The financial statements and financial highlights of the Fund for the
period presented through July 31, 2006, were audited by other auditors whose
report dated September 20, 2006, expressed an unqualified opinions on those
financial statements and financial highlights.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audit included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of July 31, 2007, by correspondence with the custodian and
brokers or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audit provides a reasonable basis for our
opinion.

          RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  59


APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

RiverSource Investments, LLC ("RiverSource"), a wholly-owned subsidiary of
Ameriprise Financial, Inc. ("Ameriprise Financial"), serves as the investment
manager to the Fund. Under an investment management services agreement (the "IMS
Agreement") RiverSource provides investment advice and other services to the
Fund and all RiverSource funds (collectively, the "Funds"). The Fund's Board of
Directors (the "Board") and the Board's Investment Review and Contracts
Committees monitor these services throughout the year.

On an annual basis, the Board, including the independent Board members (the
"Independent Directors"), considers renewal of the IMS Agreement. RiverSource
prepares detailed reports for the Board and its Contracts Committee in March and
April, including reports based on data provided by independent organizations to
assist the Board in making this determination. In addition, throughout the year,
the Board (or its committees) reviews information prepared by RiverSource
addressing the services RiverSource provides and Fund performance. The Board
accords particular weight to the work, deliberations and conclusions of the
Contracts and Investment Review Committees in determining whether to continue
the IMS Agreement. At the April 11-12, 2007 in-person Board meeting, independent
legal counsel to the Independent Directors reviewed with the Independent
Directors various factors relevant to the Board's consideration of advisory
agreements and the Board's legal responsibilities related to such consideration.
Following an analysis and discussion of the factors identified below, the Board,
including all of the Independent Directors, approved renewal of the IMS
Agreement.

Nature, Extent and Quality of Services Provided by RiverSource:  The Board
analyzed various reports and presentations it had received detailing the
services performed by RiverSource, as well as its expertise, resources and
capabilities. The Board specifically considered many developments during the
past year concerning the services provided by RiverSource, including, in
particular, the growing strength and capabilities of many RiverSource offices
and the increased investment and resources dedicated to the Fund's operations,
particularly in the areas of trading systems, legal and compliance. Further, in
connection with the Board's evaluation of the overall package of services
provided by RiverSource, the Board considered the quality of the administrative,
custody and transfer agency services provided by RiverSource affiliates to the
Fund. The Board also reviewed the financial condition of RiverSource and the
entity's ability to carry out its responsibilities under the IMS Agreement. The
Board also discussed the acceptability of the terms of the IMS Agreement
(including the relatively broad scope of services required to be performed by
RiverSource). The Board concluded that the services being performed under the
IMS Agreement were of a reasonably high quality.

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

 60 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT


Based on the foregoing, and based on other information received (both oral and
written, including the information on investment performance referenced below)
and other considerations, the Board determined that RiverSource was in a
position to continue to provide a high quality and level of services to the
Fund.

Investment Performance:  The Board observed that the Fund was first launched in
February 2006. For purposes of evaluating the nature, extent and quality of
services provided under the IMS Agreement, the Board carefully reviewed the
investment performance of the Fund. In this regard, the Board considered: (i)
detailed reports containing data prepared by an independent organization
showing, for various periods, the performance of the Fund, the performance of a
benchmark index, the percentage ranking of the Fund among its comparison group
and the net assets of the Fund; and (ii) a report detailing the Fund's
performance over various periods (including since inception) and recent Fund
inflows (and outflows).The Board observed that the Fund's investment performance
reflected the interrelationship of particular market conditions with the
specific management style employed by the portfolio management team. Further,
the Board noted that appropriate measures have been taken to modify the
disciplined quantitative method designed to lead to a more consistent
performance experience over time.

Comparative Fees, Costs of Services Provided and the Profits Realized By
RiverSource and its Affiliates from their Relationships with the Fund:  The
Board reviewed comparative fees and the costs of services to be provided under
the IMS Agreement. The Board members considered detailed comparative information
set forth in an annual report on fees and expenses, including, among other
things, data (prepared by an independent organization) showing a comparison of
the Fund's expenses with median expenses paid by funds in its peer group, as
well as data showing the Fund's contribution to RiverSource's profitability. The
Board accorded particular weight to the notion that the level of fees should
reflect a rational pricing model applied consistently across the various product
lines in the Funds' family, while assuring that the overall fees for each fund
are generally in line with the "pricing philosophy" (i.e., that the total
expense ratio of each fund, with few exceptions, is at or below the median
expense ratio of funds in the same comparison group). The Board took into
account that the Fund's total expense ratio (after considering proposed expense
caps/waivers) approximated the peer group's median expense ratio. Based on its
review, the Board concluded that the Fund's management fee was fair and
reasonable in light of the extent and quality of services that the Fund
receives.

The Board also considered the expected profitability of RiverSource and its
affiliates in connection with RiverSource providing investment management
services to the Fund. In this regard, the Board referred to a detailed
profitability report, discussing the profitability to RiverSource and Ameriprise
Financial from managing and operating the Fund, including data showing
comparative profitability. The Board also considered the services acquired by
the investment

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

          RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT  61


manager through the use of commission dollars paid by the Funds on portfolio
transactions. The Board noted that the fees paid by the Fund should permit the
investment manager to offer competitive compensation to its personnel, make
necessary investments in its business and earn an appropriate profit. The Board
concluded that profitability levels were reasonable.

Economies of Scale to be Realized:  The Board also considered the economies of
scale that might be realized by RiverSource as the Fund grows and took note of
the extent to which Fund shareholders might also benefit from such growth. The
Board considered that the IMS Agreement provides for lower fees as assets
increase at pre-established breakpoints and concluded that the IMS Agreement
satisfactorily provided for sharing these economies of scale.

Based on the foregoing, the Board, including all of the Independent Directors,
concluded that the investment management service fees were fair and reasonable
in light of the extent and quality of services provided. In reaching this
conclusion, no single factor was determinative. On April 12, 2007, the Board,
including all of the Independent Directors, approved the renewal of the IMS
Agreement.

PROXY VOTING

The policy of the Board is to vote the proxies of the companies in which the
Fund holds investments consistent with the procedures as stated in the Statement
of Additional Information (SAI). You may obtain a copy of the SAI without charge
by calling RiverSource Funds at (888) 791-3380; contacting your financial
institution; visiting riversource.com/funds; or searching the website of the
Securities and Exchange Commission (SEC) at http://www.sec.gov. Information
regarding how the Fund voted proxies relating to portfolio securities is filed
with the SEC by August 31 for the most recent 12-month period ending June 30 of
that year, and is available without charge by visiting riversource.com/funds; or
searching the website of the SEC at www.sec.gov.

CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

On April 12, 2007, Ernst & Young LLP was selected as the Fund's independent
registered public accounting firm for the 2007 fiscal year. A majority of the
Fund's Board of Directors, including a majority of the Independent Directors,
approved the appointment of Ernst & Young LLP. The predecessor independent
registered public accounting firm's reports on the Fund's financial statements
for the year ended July 31, 2006 and the year ended July 31, 2005 contained no
adverse opinion or disclaimer of opinion and were not qualified or modified as
to uncertainty, audit scope or accounting principles. During such fiscal periods
and

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

 62 RIVERSOURCE DISCIPLINED SMALL CAP VALUE FUND -- 2007 ANNUAL REPORT


through April 12, 2007 there were no disagreements between the Fund and the
predecessor independent registered public accounting firm on any matter of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedures, which such disagreements, if not resolved to the
satisfaction of the predecessor independent registered public accounting firm,
would have caused them to make reference to the subject matter of the
disagreement in connection with their reports on the financial statements for
such fiscal periods.
