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.

Lipper) and taxes.

It is not possible to invest directly in an index.

(1)  The Morgan Stanley Capital International (MSCI) EAFE Index, an unmanaged
     index, is compiled from a composite of securities markets of Europe,
     Australia and the Far East. The index is widely recognized by investors in
     foreign markets as the measurement index for portfolios of non-North
     American securities. The index reflects reinvestment of all distributions
     and changes in market prices.
(2)  The Lipper International Funds Index includes the 30 largest international
     funds (growth and value) tracked by Lipper Inc. The index's returns include
     net reinvested dividends. The Fund's performance is currently measured

 6 RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

RiverSource International Equity Fund increased 11.54% for the six-month period
ending April 30, 2007 (Class A shares, excluding sales charge), underperforming
its benchmark, the Morgan Stanley Capital International (MSCI) EAFE Index (MSCI
Index), which increased 15.68% during the same period. The Fund also
underperformed the Lipper International Funds Index, which increased 15.14%.

As of April 30, 2007, approximately 38% 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 International Equity Fund may experience relatively
large purchases or redemptions from affiliated funds-of-funds (see page 33,
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 International
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 on the Fund's expenses, see the discussions beginning on pages 12
and 30.

RiverSource International Equity Fund's portfolio is managed by two independent
money management firms that each invest a portion of the Fund's assets in a
blend of growth and value stocks of foreign companies to seek long-term growth
of capital. The Boston Company Asset Management, LLC (The Boston Company) and
Marsico Capital Management, LLC (Marsico) each managed approximately 50% of the
Fund's assets as of April 30, 2007. Below, each subadvisor discusses results and
positioning for its portion of the Fund for the semiannual period.

Q: What factors affected performance most for your portion of the Fund for the
   semiannual period ended April 30, 2007?

   THE BOSTON COMPANY: International markets shrugged off signs of a weaker U.S.
   economy and delivered robust performance over the past six months. Our
   portion of the portfolio trailed the MSCI Index during the period despite
   solid performance in the U.K., Netherlands and South Africa. Stock selection
   in the telecommunications services and information technology sectors had a
   significant positive impact on performance.

   The portfolio's country allocations had a slightly negative impact during the
   period, largely driven by an underweight in Sweden, relative to the MSCI
   Index. Sweden is a relatively small country within the MSCI Index, but turned
   in particularly strong performance late in the period. The Swedish market is
   heavily weighted with industrials companies, which rallied during the period.

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

              RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  7

QUESTIONS & ANSWERS

   The portfolio's large position in Japan had a negative impact on relative
   return. Japan failed to meet expectations for a sustainable domestic recovery
   despite a solid foundation for increased consumption. The Japanese equity
   market delivered only a modest return relative to Europe and Asia. In
   addition, Japan's financial sector continued to weigh heavily on the
   portfolio's performance.

   INTERNATIONAL MARKETS SHRUGGED OFF SIGNS OF A WEAKER U.S. ECONOMY AND
   DELIVERED ROBUST PERFORMANCE OVER THE PAST SIX MONTHS. -- THE BOSTON
   COMPANY

   In Europe, our strategy of selling top performing, more richly valued
   companies in favor of underperformers with compelling business prospects has
   remained out of favor longer than anticipated. Looking at the factors that
   drove performance of European stocks over the period, we find that value, the
   most important factor in our stock selection process, was moderately
   positive. However, other factors such as quality earnings growth, long-term
   price momentum and earnings momentum were much more significant drivers of
   return.

   The portfolio's sector allocations were a modest drag on performance, with an
   underweight in the industrials sector being a notable detractor.

   MARSICO: The portion of the Fund that we manage underperformed in comparison
   to its primary benchmark, the MSCI Index, for the six-month period. Three
   factors that detracted most significantly from performance were stock
   selection in industrials, information technology and consumer discretionary
   sectors. Individual detractors within the information technology sector
   included German based enterprise application software company SAP,
   telecommunications equipment company L.M. Ericsson Telephone and
   semiconductor-related companies Samsung Electronics, based in South Korea,
   and Advantest, based in Japan. French industrials position Vallourec, which
   manufactures steel tubing, declined sharply before we sold the stock. Price
   declines in consumer discretionary holdings such as hotel/casino operator
   Melco PBL Entertainment (Macau) Ltd., as well as Japan-based electronics
   retailer Yamada Denki and amusement game manufacturer Sega Sammy Holdings
   also hampered results.

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

 8 RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT

QUESTIONS & ANSWERS

   Currency fluctuations may at times affect investment results because the
   portfolio's foreign holdings are denominated in foreign currencies whose
   value may rise or fall against the U.S. dollar. Especially in late-2006, the
   dollar weakened relative to certain other major currencies, particularly the
   Euro. Compared to the MSCI Index, our portion of the Fund was generally
   underweight in securities priced in Euros and traded in countries that use
   the euro, including France and Germany. As a result, a smaller portion of the
   Fund benefited from the euro's valuation increase. This had a modestly
   negative impact on performance compared to the MSCI Index.

   Primary positive contributors to results included the following banking
   positions: Australia's Macquarie Bank, Italy's Intesa Sanpaolo, Industrial &
   Commercial Bank of China, Austria's Erste Bank der Oesterreichischen
   Sparkassen and Brazil's UNIBANCO Uniao de Bancos Brasileiros. Other
   financials-related companies that helped performance during the period
   included Man Group, the world's largest publicly traded hedge fund company,
   and CapitaLand, a Singapore-based real estate holding and development
   company.

   DURING THE REPORTING PERIOD, THE PORTFOLIO'S WEIGHTING IN THE CONSUMER
   DISCRETIONARY SECTOR INCREASED AND EXPOSURE TO THE INFORMATION TECHNOLOGY
   SECTOR DECREASED. -- MARSICO

   Holdings of Australia-based pharmaceutical company CSL also contributed to
   performance and Switzerland-based materials companies Lonza Group and
   Syngenta posted strong returns as well. Other top performing individual
   holdings included German auto components company Continental, Hong Kong
   fashion company Esprit Holdings and France-based water and waste management
   company Veolia Environnement.

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

   THE BOSTON COMPANY: We have been examining the portfolio's Japanese holdings
   with particular focus on stocks with consumer finance exposure. Given ongoing
   weakness, we have identified more compelling opportunities in other areas and
   began to sell Takefuji.

   MARSICO: During the reporting period, the portfolio's weighting in the
   consumer discretionary sector increased and exposure to the information
   technology sector decreased. Sector allocations in our portion of the Fund
   are typically the result of our "bottom-up" stock selection process.

Q: How are you positioning your portion of the Fund going forward?

   THE BOSTON COMPANY: Long term we remain optimistic about international
   markets. European companies have embraced restructuring, which has
   dramatically improved business prospects. Japan is poised to recover
   domestically and a broader overall market has already begun to materialize.

   We also recognize that international equity markets face some near-term
   risks, including potential for slower global economic growth,
   higher-than-expected headline inflation, monetary policy missteps by the
   central banks and pressure on consumers from higher taxes in Germany and
   Italy.

   That said, we believe the backdrop remains encouraging for equity price
   performance. Employment is high, inflation benign, oil prices have eased and
   business sentiment surveys remain positive. There is still a high level of
   liquidity in the system and strong merger and acquisition activity.
   Continental Europe should benefit from Germany's restructuring progress and
   eventual consumption rebound. Growing consumption in the emerging markets
   should aid developed markets in dealing with an aging demographic. Japanese
   equities have persistently lagged the broader MSCI Index, but despite mixed
   macro economic data, the Japanese market is forecast to deliver one of the
   highest levels of earnings growth among developed markets.

   The short, but sharp market decline at the end of February was a reminder
   that there is risk in equities and that a trend change in the market could
   drive a change in the stocks leading the market. We believe that our
   portfolio positioning should benefit from such a trend change. After four
   years of robust performance, certain valuations appear stretched. As a value
   manager, we are always cognizant of price risk embedded in securities and
   constantly look to add positions where the risk/reward opportunity is
   favorable, combined with attractive valuation characteristics.

QUESTIONS & ANSWERS

   MARSICO: The primary economic sector allocations in our portion of the Fund
   as of the period end include financials, consumer discretionary, industrials,
   materials and consumer staples. We favor these areas due to our view that
   earnings growth prospects, valuations, and macroeconomic factors, including
   interest rates, inflation, and money growth, are compelling. In terms of
   country allocations, the most significant weightings at the end of the
   six-month period were Switzerland, the U.K., Japan, France and Mexico.
   Country-level weightings should generally be considered a residual of the
   "bottom-up" stock selection process rather than a major, proactive facet of
   the investment strategy.

Any specific securities mentioned are for illustrative purposes only and are not
a complete list of securities that have increased or decreased in value. The
views expressed in this statement reflect those of the portfolio manager(s) only
through the end of the period of the report as stated on the cover and do not
necessarily represent the views of RiverSource Investments, LLC (RiverSource) or
any subadviser to the Fund or any other person in the RiverSource or subadviser
organizations. Any such views are subject to change at any time based upon
market or other conditions and RiverSource disclaims any responsibility to
update such views. These views may not be relied on as investment advice and,
because investment decisions for a RiverSource Fund are based on numerous
factors, may not be relied on as an indication of trading intent on behalf of

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 April 30, 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.

(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 April 30, 2007: +11.54%
     for Class A, +11.18% for Class B, +11.16% for Class C, +11.70% for Class I
     and +11.63% 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 Oct. 31, 2007, 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 1.43% for Class R4.
     Any amounts waived will not be reimbursed by the Fund. If these changes had
     been in place for the entire six-month period ended April 30, 2007, the
     actual and hypothetical expenses paid for Class R4 would have been the same
     as those expenses presented in the table above.

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to April 30, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

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 April 30, 2007, Ameriprise Financial, Inc. (Ameriprise Financial) and the
affiliated funds-of-funds owned 100% of Class I shares.

At April 30, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 38% 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.

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

 26 RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


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.

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

             RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  27


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. At April 30, 2007, foreign currency holdings consisted of
multiple denominations.

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.

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

 28 RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


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.

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 INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  29


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 or upon receipt of
ex-dividend notification in the case of certain foreign securities. 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 0.97% to 0.845% 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 International 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 $69,625 for the six months ended April 30, 2007.

The Investment Manager has Subadvisory Agreements with The Boston Company Asset
Management, LLC and Marsico Capital Management, LLC. 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
Fund's shareholders. Each subadviser's proportionate share of investments in the
Fund will vary due to market fluctuations.

 30 RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL 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 $1,300 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 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 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 INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  31


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 American 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.

Beginning 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
$121,906 for Class A, $11,511 for Class B and $285 for Class C for the six
months ended April 30, 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 six months ended April 30, 2007, the Investment Manager and its
affiliates waived certain fees and expenses (excluding fees and expenses of
acquired funds), such that net expenses were 1.53% for Class A, 2.30% for Class
B, 2.30% for Class C and 1.37% for Class R4. Of these waived fees and expenses,
the transfer agency fees waived for Class A, Class B, Class C and Class R4 were
$27,970, $7,062, $481 and $54, respectively. In addition, the Investment Manager
and its affiliates have agreed to waive certain fees and expenses until Oct. 31,
2007, 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 1.60% for Class A,
2.37% for Class B, 2.37% for Class C, 1.25% for Class I and 1.43% for Class R4
of the Fund's average daily net assets.

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 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. The Fund had no borrowings under the
facility outstanding during the six months ended April 30, 2007.

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.

             RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  35


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.

 36 RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


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.

 42 RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL 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"). 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.

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

             RIVERSOURCE INTERNATIONAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  43


Nature, Extent and Quality of Services Provided by RiverSource and the
Subadvisers:  The Board analyzed various reports and presentations they 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. They noted, in particular,
management's ongoing oversight and monitoring of each Subadviser's investment
process and performance.

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). Although the Fund's
expense ratio was higher than the median ratio, the Board was satisfied with the
consistent and rational fee schedule applicable to all Funds, including the
Fund. 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, they 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.
