LETTER TO SHAREHOLDERS
In this report and going forward, the Chairman of the RiverSource Funds' Boards

shareholders. Information about Stephen Lewis, Chairman of the Boards; Patrick

"Board Members and Officers" section of this report.

Dear Fellow RiverSource Funds Shareholder:

As newly appointed in our respective roles as Chairman of the Boards and
President of RiverSource Funds, we are committed to continuing the successful
leadership efforts of Ted Truscott, a member of the Boards and Chief Investment
Officer of RiverSource Investments, LLC; and Governor Arne Carlson, who served
as Chairman of the Boards for eight years and will continue to serve on the
Boards.

As RiverSource Funds shareholders, we want our investments to deliver
consistent, competitive investment performance that can help us achieve our
financial goals. We are sure you feel the same way. We are pleased to report
that the investment management teams at RiverSource Investments have delivered
on our expectations. As a result, many of our funds are receiving positive
recognition in the financial media.

When discussing your financial plans with your advisor, we encourage you to take
a long-term view. The economy is cyclical and markets are inherently volatile,
so there will be periods when economic or market conditions may appear to throw
a wrench into any portfolio. A diversified mutual fund portfolio and an
experienced financial advisor can help keep your plan on track and also keep
your expectations in line with current market realities.

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

The 5.75% sales charge applicable to Class A shares of the Fund is not reflected
in the bar chart. If reflected, returns would be lower than those shown. The
performance of other classes may vary from that shown because of differences in
expenses.

The indices do not reflect the effects of sales charges, expenses (excluding
Lipper) and taxes.

 6 RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

RiverSource Fundamental Growth Fund increased 17.25% for the 12 months ended May
31, 2007 (Class A shares excluding sales charge), underperforming its benchmark,
the Russell 1000(R) Growth Index (Russell Index), which increased 20.37% during
the same period. The Fund outperformed its peer group, as represented by the
Lipper Large-Cap Growth Funds Index, which rose 16.85%.

RiverSource Fundamental Growth Fund's portfolio is managed by two independent
money management firms. As of May 31, 2007, Goldman Sachs Asset Management, L.P.
(Goldman Sachs) and Wellington Management Company, LLP (Wellington Management)
each managed approximately 50% of the Fund's portfolio.

As of May 31, 2007, approximately 89% 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 Fundamental Growth Fund may experience relatively
large purchases or redemptions from affiliated funds-of-funds (see page 32,
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 Fundamental
Growth 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 on the Fund's expenses, see the discussions beginning on pages 14
and 28.

Q: What factors most significantly affected the performance of your portion of
   the Fund for the period?

   GOLDMAN SACHS: Favorable results in our portfolio segment came from energy
   stocks and holdings of companies that operate wireless communications towers.
   Conversely, select technology companies hampered results.

   Shares of Research In Motion, maker of BlackBerry personal digital
   assistants, contributed to performance as continued subscriber growth was
   driven by businesses adopting mobile email and introducing it more deeply
   within their organizations. Recently, shares of Research In Motion rallied on
   the company's positive outlook for long-term growth prospects. We believe
   consumer-focused BlackBerry products are broadening the brand's appeal into a
   larger market.

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

                    RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  7

QUESTIONS & ANSWERS

   Health care company MedImmune, which makes FluMist, was another leading
   contributor. In April 2007, AstraZeneca agreed to buy MedImmune at a 21%
   premium to the company's then current stock price after a competitive bidding
   process that involved at least four large pharmaceutical companies.
   Acquisitions are one way the gap between the stock price and the economic
   value of a business can close, and we believe the MedImmune example validates
   our approach of owning high quality businesses for the long term.

   Publisher McGraw-Hill Companies aided results as the company reported higher
   fiscal third quarter earnings and announced expectations to post double-
   digit earnings growth in 2007. While weakness in the education market
   remained, management attributed the company's strength to improved cost
   management and performance within its financial services segment, Standard &
   Poor's. We continue to favor Standard & Poor's, a bond ratings agency, and
   believe its strong fundamentals should enable it to sustain long-term
   double-digit growth rates.

   Shares of pharmaceutical company Amgen were weak during the period due to the
   Food and Drug Administration's (FDA) concern about doctors overprescribing
   anemia drugs as well as prescribing them for unapproved uses. We continue to
   like the company for its ability to generate free cash flow, strong balance
   sheet and emerging new product pipeline. We expect Amgen to deploy capital
   towards share repurchases and strategic acquisitions to deliver longer term
   growth.

   WELLINGTON MANAGEMENT: Stock selection in the information technology and
   financials sectors was predominantly responsible for underperformance in our
   segment of the portfolio. Among the largest detractors were SanDisk and
   Motorola in the information technology sector and Commerce Bancorp in the
   financials sector.

   Shares of storage device maker SanDisk fell in concert with falling prices on
   NAND-flash memory chips. Cell phone manufacturer Motorola stumbled as its
   revenue expectations and average selling prices weakened. Commerce Bancorp
   shares were weak largely due to the impact of the inverted yield curve.
   Short-term interest rates that the bank pays depositors have generally been
   higher than longer term rates, which are what the bank earns in interest on
   loans.

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

 8 RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT

QUESTIONS & ANSWERS

   Favorable stock selection within materials, telecommunication services and
   health care had a positive impact on results. Pharmaceutical company
   Schering-Plough, financial services firm Franklin Resources and technology
   company Adobe Systems were among the leading individual contributors to
   performance. Schering-Plough's shares rose on strong earnings results and
   investor enthusiasm for its announced acquisition of Organon Biosciences.
   Global investment manager Franklin Resources experienced favorable asset flow
   trends, while Adobe Systems benefited from solid sales and positive
   expectations for the release of its new Creative Suite 3 software product.

   FAVORABLE STOCK SELECTION WITHIN MATERIALS, TELECOMMUNICATION SERVICES AND
   HEALTH CARE HAD A POSITIVE IMPACT ON RESULTS.

                                         -- WELLINGTON MANAGEMENT

Q: What changes did you make to your portion of the Fund during the period?

   GOLDMAN SACHS: During the period, Hershey's stock was weak and detracted from
   performance. Hershey found that reigniting growth in the U.S. market was more
   difficult than anticipated and decided to increase spending on consumer
   promotion, advertising and new product development, which we believe could
   have a lasting detrimental impact on company profit margins and forecasts for
   longer term growth. We are concerned Hershey's current valuation does not
   leave enough margin of safety for the risks inherent in the proposed
   strategies for reinvigorating growth, so we sold the position in favor of
   investments that we believe have more favorable risk-reward characteristics.

   There were no material changes to the investment strategy during the period.
   When evaluating a potential investment, we look for very specific investment
   characteristics that we believe make a company a high-quality growth
   business. These criteria are divided into three categories: strong business
   franchises, favorable long-term prospects and excellent management. We also
   include a valuation component in the process.

   We typically sell a position if a company's long-term fundamentals
   deteriorate, if the stock reaches what we consider full valuation, if the
   company pursues a strategy that in our view does not maximize shareholder
   value, or if the position grows beyond a weight that is comfortable from a
   risk management standpoint.

   WELLINGTON MANAGEMENT: During the period we reduced the portfolio's weight in
   financials by cutting back exposure to banks and diversified financial
   companies. We increased exposure to information technology by establishing
   new positions in software firms Oracle and Accenture and hardware companies
   IBM and Research In Motion. We also added to industrials, ending the period
   with a greater-than-Russell Index weights in capital goods firms like General
   Dynamics and Boeing. Health care exposure declined and was smaller than that
   of the Russell Index due to reduced positions in both equipment and services
   and pharmaceuticals. Though exposure to consumer-related sectors increased as
   we added positions in office retailer Staples and apparel firm Nike, the
   portfolio's weight remained smaller than that of the Russell Index.

Q. How do you intend to manage your portion of the Fund in the coming months?

   GOLDMAN SACHS: For the past several years, strong global growth has supported
   the persistent outperformance of lower quality companies, creating a
   difficult headwind for our style. Today there are signs the environment may
   be changing, making us optimistic that higher quality stocks are positioned
   to better reflect their underlying business values.

   As business buyers, we do not attempt to predict the economy or position the
   portfolio for any specific economic environment, but we believe there is
   currently a great opportunity for investing in quality growth stocks. To us,
   quality boils down to sustainability of growth, returns, margin structure,
   competitive advantage, etc. In our research, we look for specific
   characteristics that give us confidence in this sustainability. We believe
   that if a business has a dominant market position, a long product lifecycle,
   pricing power and the ability to generate significant free cash flow that
   management rationally allocates, then the business will have the barriers to
   entry required to drive high returns on equity, and therefore an increase in
   its economic value. Over time, we believe the stock price of that business
   will reflect this value.

QUESTIONS & ANSWERS

   WELLINGTON MANAGEMENT: We continue to use security-specific research to build
   our portion of the Fund one stock at a time. We seek to identify individual
   companies that possess an explicit sustainable growth advantage or barrier to
   entry that will enable them to maintain an above-average growth rate for an
   extended period. As a result of bottom-up investment decisions, our segment
   ended the period with information technology and industrials as its largest
   overweights and consumer staples and consumer discretionary as its largest
   underweights, all relative to the Russell Index.

THE FUND'S LONG-TERM PERFORMANCE

The chart on the facing page illustrates the total value of an assumed $10,000
investment in RiverSource Fundamental Growth Fund Class A shares (from 5/1/03 to
5/31/07)* as compared to the performance of two widely cited performance
indices, the Russell 1000(R) Growth Index and the Lipper Large-Cap Growth 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 FUNDAMENTAL GROWTH 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 May 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>

(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 182/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended May 31, 2007: +9.19%
     for Class A, +8.65% for Class B, +8.64% for Class C, +9.38% for Class I and
     +9.10% for Class R4.
(c)  In September 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 an account-based fee to an
     asset-based fee, and adopting a plan administration services agreement.
     These changes were effective Dec. 11, 2006. In addition, the investment
     manager and its affiliates have contractually agreed to waive certain fees
     and to absorb certain expenses until May 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: 1.42% for Class A, 2.18%
     for Class B, 2.18% for Class C, 0.99% for Class I and 1.29% for Class R4.
     Any amounts waived will not be reimbursed by the Fund. This change was
     effective June 1, 2007. If these changes had been in place for the entire
     six months ended May 31, 2007, the actual and hypothetical expenses paid
     for Class A, Class B, Class C, Class I and Class R4 would have been the
     same as those expenses presented in the table above.

 22 RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Managers Series, Inc. and is registered
under the Investment Company Act of 1940 (as amended) as a diversified, open-end
management investment company. RiverSource Managers 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 publicly traded
U.S. securities.

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 May 31, 2007, Ameriprise Financial, Inc. (Ameriprise Financial) and the
affiliated funds-of-funds owned 100% of Class I shares.

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

All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration 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.

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

                   RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  23


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. 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.

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.
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.

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

 24 RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT


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.

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.

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 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 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.

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

                   RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  25


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 increased by $671,602
and accumulated net realized gain has been decreased by $671,602.

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 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.

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

                   RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  27


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, RiverSource Investments, LLC
(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 0.78% to 0.68% 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 Large-Cap Growth 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 increased the fee by $3,495 for the year ended May 31, 2007.

The Investment Manager has Subadvisory Agreements with Goldman Sachs Asset
Management, L.P. and Wellington Management Company, LLP. New investments in the
Fund, net of any redemptions, are allocated in accordance with the Investment
Manager's determination of the allocation that is in the best interests of the
shareholders. Each subadviser's proportionate share of investments in the Fund

 28 RIVERSOURCE FUNDAMENTAL GROWTH 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 0.06% to 0.03% annually as the
Fund's assets increase.

Other expenses in the amount of $5,352 is 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 the former Board Chair, compensation
as well as retirement benefits. Certain other aspects of the 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 auditor 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.

Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate per
shareholder account of $1. This amount is included in the transfer agency fee on
the statement of operations. Effective Dec. 11, 2006, this fee was eliminated.

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

                   RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  29


The Transfer Agent charges an annual closed account 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 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 new 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
$44,880 for Class A, $8,322 for Class B and $4 for Class C for the year ended
May 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.

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

 30 RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT


The Investment Manager and its affiliates agreed to waive certain fees and
expenses until May 31, 2007, such that net expenses (excluding fees and expenses
of acquired funds), before giving effect to any performance incentive
adjustment, would not exceed 1.55% for Class A, 2.32% for Class B, 2.32% for
Class C, 1.20% for Class I and 1.32% for Class R4 of the Fund's average daily
net assets. For the year ended May 31, 2007, the waiver was not invoked since
the Fund's expenses were below the cap amount. Effective June 1, 2007, the
Investment Manager and its affiliates have agreed to waive certain fees and
expenses until May 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
1.42% for Class A, 2.18% for Class B, 2.18% for Class C, 0.99% for Class I and
1.29% for Class R4 of the Fund's average daily net assets.

During the year ended May 31, 2007, the Fund's custodian and transfer agency
fees were reduced by $1,892 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.

In addition, the Fund received a one time payment of $17 by Ameriprise Financial
for additional earnings from overnight cash balances determined to be owed for
prior years. This amount was insignificant to the Fund's net asset value and
total return.

3. SECURITIES TRANSACTIONS

5. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund,
a money market fund established for the exclusive use of the RiverSource funds
and other institutional clients of RiverSource Investments.

6. 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 May 31, 2007.

7. 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.

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

                   RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  33


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.

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

 34 RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT


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.

                   RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  47


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"). In addition, under
the subadvisory agreements between RiverSource and each subadviser
(collectively, the "Subadvisers") (the "Subadvisory Agreements"), the
Subadvisers perform portfolio management and related services for the Fund. 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 and the
Subadvisory Agreements (together, the "Advisory Agreements"). 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 Advisory Agreements. 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 Advisory Agreements.

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

 48 RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT


Nature, Extent and Quality of Services Provided by RiverSource and the
Subadvisers:  The Board analyzed various reports and presentations it had
received detailing the services performed by RiverSource and the Subadvisers, as
well as their 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 each Subadviser, and each entity's
ability to carry out its responsibilities under the Advisory Agreements. The
Board also discussed the acceptability of the terms of the Advisory Agreements
(including the relatively broad scope of services required to be performed by
RiverSource and each Subadviser). The Board concluded that the services being
performed under the Advisory Agreements were of a reasonably high quality.

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 and each of the
Subadvisers were in a position to continue to provide a high quality and level
of services to the Fund.

Investment Performance:  For purposes of evaluating the nature, extent and
quality of services provided under the Advisory Agreements, 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), recent Fund
inflows (and outflows) and a comparison of the Fund's net assets from December
2006 to December 2005. The Board observed that the Fund's investment performance
was appropriate in light of the particular management style and market
conditions involved. Additionally, the Board reviewed the performance of the
Subadvisers and the overall "subadvised" strategy. The Board noted, in
particular, management's ongoing oversight and monitoring of each Subadviser's
investment process and performance.

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

                   RIVERSOURCE FUNDAMENTAL GROWTH FUND -- 2007 ANNUAL REPORT  49


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 Advisory Agreements. 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 over the last three years. 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 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 and subadvisory 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 Advisory Agreements.
