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

The 5.75% sales charge applicable to Class A shares of the Fund is not reflected
in the table above. If reflected, returns would be lower than those shown. The
performance of other classes may vary from that shown because of differences in
expenses. See the Average Annual Total Returns table for performance of other
share classes of the Fund.

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

(1) The Morgan Stanley Capital International (MSCI) EAFE Index, an unmanaged
    index, is compiled from a composite of securities markets of Europe,

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

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

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

(a) In addition to the Fund's total annual operating expenses that the Fund
    bears directly, the Fund's shareholders indirectly bear the expenses of
    acquired funds in which the Fund invests. The Fund's "acquired fund fees and
    expenses," based on its investment in the acquired funds, is 0.03% for the
    year ended Oct. 31, 2008.

*   Fund expense ratios are calculated based on the fund's average net assets
    during the fund's most recently completed fiscal year, and have not been
    adjusted for current asset levels, including any decrease or increase in
    assets, which, if adjusted, would result in expense ratios that are higher
    or lower, respectively, than those that are expressed herein. Any fee
    waivers/expense caps would limit the impact that any decrease in assets will
    have on net expense ratios in the current fiscal year.

International investing involves increased risk and volatility due to potential
political and economic instability, currency fluctuations, and differences in
financial reporting and accounting standards and oversight. Risks are
particularly significant in emerging markets.

8  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT



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

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1) fees;
and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the 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 expense ratio of each of the acquired funds as of the acquired fund's
most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2009.

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.

FAIR VALUE MEASUREMENTS


Statement of Financial Accounting Standards No. 157 (SFAS 157) seeks to
implement more uniform reporting relating to the fair valuation of securities
for financial statement purposes. Mutual funds are required to implement the
requirements of this standard for fiscal years beginning after Nov. 15, 2007.
While uniformity of presentation is the objective of the standard, it is likely
that there may be a range of practices utilized and it may be some period of
time before industry practices become more uniform. For this reason care should
be exercised in interpreting this information and/or using it for comparison
with other mutual funds.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below:

     - Level 1 -- quoted prices in active markets for identical securities

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

     - Level 3 -- significant unobservable inputs (including the Fund's own
       assumptions in determining the fair value of investments)

Observable inputs are those based on market data obtained from sources
independent of the Fund, and unobservable inputs reflect the Fund's own
assumptions based on the best information available. The input levels are not
necessarily an indication of the risk or liquidity associated with investments
at that level. Non-U.S. equity securities actively traded in foreign markets may
be reflected in Level 2 despite the availability of closing prices, because the
Fund evaluates and determines whether those closing prices reflect fair value at
the close of the NYSE or require adjustment, as described in Note 1 to the
financial statements -- Valuation of securities.

The following table is a summary of the inputs used to value the Fund's
investments as of April 30, 2009:

(UNAUDITED AS TO APRIL 30, 2009)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RiverSource Disciplined International Equity Fund (the Fund) is a series of
RiverSource International Series, Inc. and is registered under the Investment
Company Act of 1940 (as amended) as a diversified, open-end management
investment company. RiverSource International Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Board of Directors (the Board). The Fund invests
primarily in equity securities of foreign issuers or in instruments that provide
exposure to foreign equity markets. The Fund may invest in securities of or
instruments that provide exposure to both developed and emerging markets
issuers.

The Fund offers Class A, Class B, Class C, Class I, Class R2, Class R3, Class
R4, Class R5 and Class W 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, Class R2, Class R3, Class R4 and Class R5 shares are sold without a
   front-end sales charge or CDSC and are offered to qualifying institutional
   investors.

- -  Class W shares are sold without a front-end sales charge or CDSC and are
   offered through qualifying discretionary accounts.

At April 30, 2009, RiverSource Investments, LLC (RiverSource Investments or the
Investment Manager) and the RiverSource affiliated funds-of-funds owned 100% of
Class I shares, and the Investment Manager owned 100% of Class R2, Class R3 and
Class R5 shares.

All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration services fees) differ among classes. Income, expenses
(other than class specific expenses) and realized and unrealized gains or losses
on investments are allocated to each class of shares based upon its relative net
assets.

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,

- --------------------------------------------------------------------------------
36  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT



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



liabilities and contingent assets and liabilities) that could differ from actual
results.

VALUATION OF SECURITIES
Effective Nov. 1, 2008, the Fund adopted Statement of Financial Accounting
Standards No. 157 "Fair Value Measurements" (SFAS 157). SFAS 157 establishes an
authoritative definition of fair value, sets out a hierarchy for measuring fair
value, and requires additional disclosures about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported in
the Statement of Operations for a fiscal period. There was no impact to the
Fund's net assets or results of operations upon adoption. The fair valuation
measurements disclosure can be found following the Notes to Portfolio of
Investments.

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.
When market quotes are not readily available, the pricing service, in
determining fair values of debt securities, takes into consideration such
factors as current quotations by broker/dealers, coupon, maturity, quality, type
of issue, trading characteristics, and other yield and risk factors it deems
relevant in determining valuations. Foreign securities are valued based on
quotations from the principal market in which such securities are normally
traded. The procedures adopted by the Board generally contemplate the use of
fair valuation in the event that price quotations or valuations are not readily
available, price quotations or valuations from other sources are not reflective
of market value and thus deemed unreliable, or a significant event has occurred
in relation to a security or class of securities (such as foreign securities)
that is not reflected in price quotations or valuations from other sources. A
fair value price is a good faith estimate of the value of a security at a given
point in time.

Many securities markets and exchanges outside the U.S. close prior to the close
of the New York Stock Exchange (NYSE) and therefore the closing prices for
securities in such markets or on such exchanges may not fully reflect events
that occur after such close but before the close of the NYSE, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial, Inc. (Ameriprise
Financial), parent company of the Investment Manager, as administrator to the
Fund, will fair value foreign securities pursuant to procedures adopted by the
Board, including utilizing a third party pricing service to determine these fair
values. These

- --------------------------------------------------------------------------------
 RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT  37



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



procedures take into account multiple factors, including movements in the U.S.
securities markets, to determine a good faith estimate that reasonably reflects
the current market conditions as of the close of the NYSE.

Short-term securities maturing in more than 60 days from the valuation date are
valued at the market price or approximate market value based on current interest
rates; those maturing in 60 days or less are valued at amortized cost, which
approximates fair value.

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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. Option
contracts, including OTC option contracts, with no readily available market
value are valued using quotations obtained from independent brokers as of the
close of the NYSE. The Fund will realize a gain or loss when the option
transaction expires or is exercised. When an option is exercised, the proceeds
on sales for a written call option, the purchase cost for a written put option
or the cost of a security for a purchased put or call option is adjusted by the
amount of premium received or paid. At April 30, 2009, and for the six months
then ended, the Fund had no outstanding option contracts.

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

- --------------------------------------------------------------------------------
38  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT



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



illiquid market and that a change in the value of the contract or option may not
correlate with changes in the value of the underlying securities.

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

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS
Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate 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 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 counterparty will not
complete its contract obligations. At April 30, 2009, the Fund had no
outstanding forward foreign currency contracts.

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


- --------------------------------------------------------------------------------
 RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT  39



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


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.

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

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

RECENT ACCOUNTING PRONOUNCEMENTS
The Fund has adopted FASB Staff Position No. 133-1 and FIN No. 45-4 (FSP FAS
133-1 and FIN 45-4), "Disclosures about Credit Derivatives and Certain
Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No.
45." The amendments to FSP FAS 133-1 and FIN 45-4 require enhanced disclosures
about a fund's derivatives and guarantees. Funds are required to provide
enhanced disclosures about (a) how and why a fund uses derivative instruments,
(b) how derivative instruments and related hedged items are accounted for under
SFAS 133 and its related interpretations, (c) how derivative instruments and
related hedged items affect a fund's financial position, financial performance,
and cash flows and (d) the current status of the payment/performance risk of the
credit derivative. The amendments to FSP FAS 133-1 and FIN 45-4 also require
additional disclosures about the current status of the payment/performance risk
of a guarantee. At April 30, 2009, the Fund did not own nor was it a party to
any credit derivative contracts within the scope of these amendments.

In March 2008, the FASB issued Statement of Financial Accounting Standards No.
161 (SFAS 161), "Disclosures about Derivative Instruments and Hedging
Activities -- an amendment of FASB Statement No. 133," which requires enhanced
disclosures about a fund's derivative and hedging activities. SFAS 161 is
effective for financial statements issued for fiscal years and interim periods

- --------------------------------------------------------------------------------
40  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT



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




beginning after Nov. 15, 2008. As of April 30, 2009, management does not believe
the adoption of SFAS 161 will impact the financial statement amounts; however,
additional footnote disclosures may be required about the use of derivative
instruments and hedging items.

On April 9, 2009, the FASB issued Staff Position No. 157-4, "Determining Fair
Value When the Volume and Level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly" (FSP
157-4). FSP 157-4 provides additional guidance for estimating fair value in
accordance with SFAS 157 when the volume and level of activity for the asset or
liability have significantly decreased. FSP 157-4 also requires additional
disaggregation of the current SFAS 157 required disclosures. FSP 157-4 is
effective for interim and annual reporting periods ending after June 15, 2009,
and shall be applied prospectively. Management is currently evaluating the
impact that the adoption of FSP 157-4 will have on the amounts and disclosures
within the Fund's financial statements.

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

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date 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

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Fund's average daily net assets that declines from 0.80%
to 0.57% annually as the Fund's assets increase. The fee may be adjusted upward
or downward by a performance incentive adjustment determined monthly by
measuring the percentage difference over a rolling 12-month period between the
annualized performance of one Class A share of the Fund and the annualized
performance of the Lipper International Large-Cap Core Funds Index. In certain
circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year. If the performance difference is less than 0.50%,

- --------------------------------------------------------------------------------
 RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT  41



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


the adjustment will be zero. The adjustment decreased the management fee by
$379,541 for the six months ended April 30, 2009. The management fee for the six
months ended April 30, 2009 was 0.57% of the Fund's average daily net assets,
including the adjustment under the terms of the performance incentive
arrangement.

ADMINISTRATIVE SERVICES FEES
Under an Administrative Services Agreement, the Fund pays Ameriprise Financial 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. The fee for the six months ended April 30, 2009 was
0.08% of the Fund's average daily net assets.

OTHER FEES
Other expenses are for, among other things, certain expenses of the Fund or the
Board including: Fund boardroom and office expense, employee compensation,
employee health and retirement benefits, and certain other expenses. Payment of
these Fund and Board expenses is facilitated by a company providing limited
administrative services to the Fund and the Board. For the six months ended
April 30, 2009, other expenses paid to this company were $1,838.

COMPENSATION OF BOARD MEMBERS
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.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains shareholder accounts and records. The Fund pays the Transfer
Agent an annual account-based fee at a rate equal to $19.50 for Class A, $20.50
for Class B and $20.00 for Class C for this service. The Fund also pays the
Transfer Agent an annual asset-based fee at a rate of 0.05% of the Fund's
average daily net assets attributable to Class R2, Class R3, Class R4 and Class
R5 shares and an annual asset-based fee at a rate of 0.20% of the Fund's average
daily net assets attributable to Class W shares.

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


- --------------------------------------------------------------------------------
42  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT



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



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

DISTRIBUTION FEES
The Fund has agreements with RiverSource Distributors, Inc. and RiverSource Fund
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, Class R3 and Class W shares, a
fee at an annual rate of up to 0.50% of the Fund's average daily net assets
attributable to Class R2 shares and a fee at an annual rate of up to 1.00% of
the Fund's average daily net assets attributable to Class B and Class C shares.
For Class B and Class C shares, up to 0.75% of the fee is reimbursed for
distribution expenses.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed expense") was approximately $388,000 and $12,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of April 30, 2009, and may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges received by the Distributor for distributing Fund shares were
$32,986 for Class A, $3,115 for Class B and $22 for Class C for the six months
ended April 30, 2009.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the six months ended April 30, 2009, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds*), including the adjustment under
the terms of a performance incentive arrangement, were as follows:

<Table>
                                                   
Class R2............................................  1.38%
Class R3............................................  1.15
Class R4............................................  0.90
</Table>




- --------------------------------------------------------------------------------
 RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT  43



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


The waived/reimbursed fees and expenses for the plan administration services
fees at the class level were as follows:

<Table>
                                                    
Class R2.............................................   $2
Class R3.............................................    2
Class R4.............................................   37
</Table>


The Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses until Oct. 31, 2009, 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 the following percentage of the class average daily net assets:

<Table>
                                                   
Class R4............................................  1.37%
</Table>


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

CUSTODIAN FEES
Effective Dec. 15, 2008, the Fund pays custodian fees to JPMorgan Chase Bank,
N.A. For the period from Nov. 1, 2008 to Dec. 15, 2008, the Fund paid custodian
fees amounting to $5,223 to Ameriprise Trust Company, a subsidiary of Ameriprise
Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $144,217,675 and $210,940,905, respectively, for the six
months ended April 30, 2009. Realized gains and losses are determined on an
identified cost basis.

5. LENDING OF PORTFOLIO SECURITIES

Effective Dec. 1, 2008, the Fund has entered into a Master Securities Lending
Agreement ("the Agreement") with JPMorgan Chase Bank, National Association
("JPMorgan"). The Agreement authorizes JPMorgan as lending agent to lend
securities to authorized borrowers in order to generate additional income on
behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured
by cash or U.S. government securities equal to at least 100% of the market value
of the loaned securities. Any additional collateral required to maintain those
levels due to market fluctuations of the loaned securities is delivered the
following business day. Cash collateral received is invested by the lending
agent on behalf of the Fund into authorized investments pursuant to the
Agreement. The investments made with the cash collateral are listed in the
Portfolio of

- --------------------------------------------------------------------------------
 RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT  45



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



Investments. The value of such investments, and any uninvested cash collateral
balance, are disclosed in the Statement of Assets and Liabilities along with the
related obligation to return the collateral upon the return of the securities
loaned. At April 30, 2009, securities valued at $43,779,612 were on loan,
secured by cash collateral of $44,982,057 invested in short-term securities or
in cash equivalents.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Income of
$167,336 earned from securities lending from Dec. 1, 2008 through April 30, 2009
is included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

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

Prior to Dec. 1, 2008, the Investment Manager served as securities lending agent
for the Fund under the Securities Lending Agency Agreement. For the period from
Nov. 1, 2008 through Nov. 30, 2008, the Fund had no securities on loan.

6. 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. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash Fund aggregated $60,807,094 and $78,752,545, respectively, for the six
months ended April 30, 2009. The income distributions received with respect to
the Fund's investment in RiverSource Short-Term Cash Fund can be found in the
Statement of Operations and the Fund's invested balance in RiverSource Short-
Term Cash Fund at April 30, 2009, can be found in the Portfolio of Investments.

7. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility agreement, which is a
collective agreement between the Fund and certain other RiverSource funds,
severally and not jointly, permits collective borrowings up to $475 million. The
borrowers shall have the right, upon written notice to the Administrative Agent
to request an increase of up to $175 million in the aggregate amount of the
credit facility from new or existing lenders, provided that the aggregate amount
of the credit facility shall at no time exceed $650 million. Participation in
such increase by any existing lender shall be at such lender's sole discretion.
Interest is charged to each Fund based on its borrowings at a rate equal to the
federal funds rate plus 0.75%. Each borrowing under the credit facility matures
no later than 60 days after the date of borrowing. The Fund also pays a
commitment fee equal to its pro rata share of the amount of the credit facility
at a rate of 0.06% per annum, in addition to an upfront fee equal to its pro
rata share of 0.02% of the amount of the credit facility. The Fund had no
borrowings during the six months ended April 30, 2009.

8. FUND MERGER

At the close of business on March 14, 2008, RiverSource Disciplined
International Equity Fund acquired the assets and assumed the identified
liabilities of RiverSource International Equity Fund. The reorganization was
completed after shareholders approved the plan on Jan. 29, 2008.

The aggregate net assets of RiverSource Disciplined International Equity Fund
immediately before the acquisition were $608,113,836 and the combined net assets
immediately after the acquisition were $784,324,248.

The merger was accomplished by a tax-free exchange of 31,950,545 shares of
RiverSource International Equity Fund valued at $176,210,412.

9. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$23,521,188 at Oct. 31, 2008, that if not offset by capital gains will expire in
2016. It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires.

10. RISKS RELATING TO CERTAIN INVESTMENTS

FOREIGN\EMERGING MARKETS RISK
Investing in foreign securities may include certain risks and considerations not
typically associated with investing in U.S. securities, such as fluctuating
currency values and changing local and regional economic, political and social
conditions, which may result in greater market volatility. In addition, certain
foreign securities may not be as liquid as U.S. securities. Investing in
emerging markets may accentuate these risks.

11. 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

- --------------------------------------------------------------------------------
48  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT



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




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 (the District Court). In response to defendants'
motion to dismiss the complaint, the District Court dismissed one of plaintiffs'
four claims and granted plaintiffs limited discovery. Defendants moved for
summary judgment in April 2007. Summary judgment was granted in the defendants'
favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth
Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8,
2009, the Eighth Circuit reversed summary judgment and remanded to the District
Court for further proceedings.

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

On November 7, 2008, RiverSource Investments, LLC, a subsidiary of Ameriprise
Financial, Inc., acquired J. & W. Seligman & Co., Inc. (Seligman). In late 2003,
Seligman conducted an extensive internal review concerning mutual fund trading
practices. Seligman's review, which covered the period 2001-2003, noted one
arrangement that permitted frequent trading in certain open-end registered
investment companies managed by Seligman (the Seligman Funds); this arrangement
was in the process of being closed down by Seligman before September 2003.
Seligman identified three other arrangements that permitted frequent trading,
all of which had been terminated by September 2002. In

- --------------------------------------------------------------------------------
 RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT  49



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



January 2004, Seligman, on a voluntary basis, publicly disclosed these four
arrangements to its clients and to shareholders of the Seligman Funds. Seligman
also provided information concerning mutual fund trading practices to the SEC
and the Office of the Attorney General of the State of New York (NYAG).

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

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

50  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL 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.

APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT ----------------------------------------------------------------------

RiverSource Investments, LLC ("RiverSource Investments" or the "investment
manager"), 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 Investments
provides investment advice and other services to the Fund and all funds in the
RiverSource Family of Funds (collectively, the "Funds").

On an annual basis, the Fund's Board of Directors (the "Board"), including the
independent Board members (the "Independent Directors"), considers renewal of
the IMS Agreement. RiverSource Investments prepared detailed reports for the
Board and its Contracts Committee in March and April 2009, 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 Investments addressing
the services RiverSource Investments provides and Fund performance. The Board
accords particular weight to the work, deliberations and conclusions of the
Contracts, Investment Review and Compliance Committees in determining whether to
continue the IMS Agreement. At the April 7-8, 2009 in-person Board meeting,
independent legal counsel to the Independent Directors reviewed with the
Independent Directors various factors relevant to the Board's consideration of
advisory agreements and the Board's legal responsibilities related to such
consideration. Following an analysis and discussion of the factors identified
below, the Board, including all of the Independent Directors, approved renewal
of the IMS Agreement.

Nature, Extent and Quality of Services Provided by RiverSource Investments:  The
Board analyzed various reports and presentations it had received detailing the
services performed by RiverSource Investments, as well as its expertise,
resources and capabilities. The Board specifically considered many developments
during the past year concerning the services provided by RiverSource
Investments, including, in particular, the continued investment in, and
resources dedicated to, the Fund's operations, most notably, the large
investment made in the acquisition of J. & W. Seligman & Co. Incorporated,
including its portfolio management operations, personnel and infrastructure
(including the addition of two new offices in New York City and Palo Alto).
Further, in connection with the Board's evaluation of the overall package of
services provided by RiverSource Investments, the Board considered the quality
of the administrative and transfer agency services provided by RiverSource
Investments' affiliates to the Fund. The Board also reviewed the financial
condition of RiverSource Investments (and its affiliates) and each entity's
ability to carry out its responsibilities under the IMS Agreement. Further, the
Board considered RiverSource Investments' ability to

- --------------------------------------------------------------------------------
52  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT



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



retain key personnel and its expectations in this regard. The Board also
discussed the acceptability of the terms of the IMS Agreement (including the
relatively broad scope of services required to be performed by RiverSource
Investments). The Board concluded that the services being performed under the
IMS Agreement were of a reasonably high quality, particularly in light of recent
market conditions.

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 concluded that RiverSource Investments and
its affiliates 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 IMS Agreement, the Board carefully
reviewed the investment performance of the Fund. In this regard, the Board
considered: (i) detailed reports containing data prepared by an independent
organization showing, for various periods, the performance of the Fund, the
performance of a benchmark index, the percentage ranking of the Fund among its
comparison group and the net assets of the Fund; and (ii) a report detailing the
Fund's performance over various periods, recent Fund inflows (and outflows) and
a comparison of the Fund's net assets from December 2007 to December 2008. The
Board observed that the Fund's investment performance reflected the
interrelationship of exceptionally challenging market conditions with the
investment strategies employed by the portfolio management team. Further, the
Board noted that appropriate measures have been taken to adjust the quantitative
investment processes in response to recent market conditions.

Comparative Fees, Costs of Services Provided and the Profits Realized By
RiverSource Investments and its Affiliates from their Relationships with the
Fund:  The Board reviewed comparative fees and the costs of services to be
provided under the IMS Agreement. The Board members considered detailed
comparative information set forth in an annual report on fees and expenses,
including, among other things, data (prepared by an independent organization)
showing a comparison of the Fund's expenses with median expenses paid by funds
in its peer group, as well as data showing the Fund's contribution to
RiverSource Investments' profitability. They also reviewed information in the
report comparing the fees charged to the Fund by RiverSource Investments to fees
charged to other client accounts (with similar investment strategies to those of
the Fund).


- --------------------------------------------------------------------------------
 RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2009 SEMIANNUAL REPORT  53



APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT (continued) ----------------------------------------------------------


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 (excluding the effect of a performance incentive
adjustment, if applicable), with few exceptions, is at or below the median
expense ratio of funds in the same comparison group). The Board took into
account that the Fund's total expense ratio (after considering proposed expense
caps/waivers) was slightly below the peer group's median expense ratio shown in
the reports. The Board also considered the Fund's performance incentive
adjustment and noted its continued appropriateness.

The Board also considered the expected profitability of RiverSource Investments
and its affiliates in connection with RiverSource Investments providing
investment management services to the Fund. In this regard, the Board referred
to a detailed profitability report, discussing the profitability to RiverSource
Investments and Ameriprise Financial from managing and operating the Fund,
including data showing comparative profitability over the past two 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 Investments as the Fund grows and
took note of the extent to which Fund shareholders might also benefit from such
growth. The Board considered that the IMS Agreement provides for lower fees as
assets increase at pre-established breakpoints and concluded that the IMS
Agreement satisfactorily provided for sharing these economies of scale.

Based on the foregoing, the Board, including all of the Independent Directors,
concluded that the investment management service fees were fair and reasonable
in light of the extent and quality of services provided. In reaching this
conclusion, no single factor was determinative. On April 8, 2009, the Board,
including all of the Independent Directors, approved the renewal of the IMS
Agreement for an additional annual period.

* Not annualized.

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

The 5.75% sales charge applicable to Class A shares of the Fund is not reflected
in the table above. If reflected, returns would be lower than those shown. The
performance of other classes may vary from that shown because of differences in
expenses. See the Average Annual Total Returns table for performance of other
share classes of the Fund.

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

(1) The Morgan Stanley Capital International (MSCI) Europe Index, compiled by
    MSCI in Geneva, is an unmanaged market-capitalization-weighted index of
    equity securities from various European countries. Income is included. The
    index reflects reinvestment of all distributions and changes in market
    prices.

(2) The Lipper European Funds Index includes the 30 largest European funds
    tracked by Lipper Inc. The index's returns include net reinvested dividends.
    The Fund's performance is currently measured against this index for purposes
    of determining the performance incentive adjustment.

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

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

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

(a) The Investment Manager and its affiliates have contractually agreed to waive
    certain fees and to absorb certain expenses until Oct. 31, 2009, unless
    sooner terminated at the discretion of the Fund's Board. Any amounts waived
    will not be reimbursed by the Fund. Under this agreement, net fund expenses
    (excluding fees and expenses of acquired funds), before giving effect to any
    performance incentive adjustment (that increased the management fee by 0.02%
    for the year ended Oct. 31, 2008), will not exceed 1.46% for Class A, 2.23%
    for Class B, 2.22% for Class C, 1.01% for Class I and 1.31% for Class R4.

*   Fund expense ratios are calculated based on the fund's average net assets
    during the fund's most recently completed fiscal year, and have not been
    adjusted for current asset levels, including any decrease or increase in
    assets, which, if adjusted, would result in expense ratios that are higher
    or lower, respectively, than those that are expressed herein. Any fee
    waivers/expense caps would limit the impact that any decrease in assets will
    have on net expense ratios in the current fiscal year.

International investing involves increased risk and volatility due to potential
political and economic instability, currency fluctuations, and differences in
financial reporting and accounting standards and oversight. Risks are
particularly significant in emerging markets.

6  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



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

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1) fees;
and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the 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 expense ratio of each of the acquired funds as of the acquired fund's
most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2009.

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.

FAIR VALUE MEASUREMENTS


Statement of Financial Accounting Standards No. 157 (SFAS 157) seeks to
implement more uniform reporting relating to the fair valuation of securities
for financial statement purposes. Mutual funds are required to implement the
requirements of this standard for fiscal years beginning after Nov. 15, 2007.
While uniformity of presentation is the objective of the standard, it is likely
that there may be a range of practices utilized and it may be some period of
time before industry practices become more uniform. For this reason care should
be exercised in interpreting this information and/or using it for comparison
with other mutual funds.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below:

     - Level 1 -- quoted prices in active markets for identical securities

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

     - Level 3 -- significant unobservable inputs (including the Fund's own
       assumptions in determining the fair value of investments)

Observable inputs are those based on market data obtained from sources
independent of the Fund, and unobservable inputs reflect the Fund's own
assumptions based on the best information available. The input levels are not
necessarily an indication of the risk or liquidity associated with investments
at that level. Non-U.S. equity securities actively traded in foreign markets may
be reflected in Level 2 despite the availability of closing prices, because the
Fund evaluates and determines whether those closing prices reflect fair value at
the close of the NYSE or require adjustment, as described in Note 1 to the
financial statements -- Valuation of securities.

The following table is a summary of the inputs used to value the Fund's
investments as of April 30, 2009:

22  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



NOTES TO FINANCIAL STATEMENTS --------------------------------------------------
(UNAUDITED AS TO APRIL 30, 2009)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Threadneedle European Equity Fund (the Fund) is a series of RiverSource
International Series, Inc. and is registered under the Investment Company Act of
1940 (as amended) as a diversified, open-end management investment company.
RiverSource International Series, Inc. has 10 billion authorized shares of
capital stock that can be allocated among the separate series as designated by
the Board of Directors (the Board). The Fund invests primarily in equity
securities of European companies that are believed to offer growth potential.

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 R4 shares are sold without a front-end sales charge or CDSC and
   are offered to qualifying institutional investors.

At April 30, 2009, RiverSource Investments, LLC (RiverSource Investments or the
Investment Manager) owned 100% of Class I shares.

All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration services fees) differ among classes. Income, expenses
(other than class specific expenses) and realized and unrealized gains or losses
on investments are allocated to each class of shares based upon its relative net
assets.

The Fund's significant accounting policies are summarized below:

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

VALUATION OF SECURITIES
Effective Nov. 1, 2008, the Fund adopted Statement of Financial Accounting
Standards No. 157 "Fair Value Measurements" (SFAS 157). SFAS 157 establishes an
authoritative definition of fair value, sets out a hierarchy for measuring fair
value, and requires additional disclosures about the inputs used to develop the
measurements of fair value and the effect of certain measurements

- --------------------------------------------------------------------------------
                 THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT  23



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

reported in the Statement of Operations for a fiscal period. There was no impact
to the Fund's net assets or results of operations upon adoption. The fair
valuation measurements disclosure can be found following the Notes to Portfolio
of Investments.

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.
When market quotes are not readily available, the pricing service, in
determining fair values of debt securities, takes into consideration such
factors as current quotations by broker/dealers, coupon, maturity, quality, type
of issue, trading characteristics, and other yield and risk factors it deems
relevant in determining valuations. Foreign securities are valued based on
quotations from the principal market in which such securities are normally
traded. The procedures adopted by the Board generally contemplate the use of
fair valuation in the event that price quotations or valuations are not readily
available, price quotations or valuations from other sources are not reflective
of market value and thus deemed unreliable, or a significant event has occurred
in relation to a security or class of securities (such as foreign securities)
that is not reflected in price quotations or valuations from other sources. A
fair value price is a good faith estimate of the value of a security at a given
point in time.

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

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, which
approximates fair value.

24  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



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


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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. Option
contracts, including OTC option contracts, with no readily available market
value are valued using quotations obtained from independent brokers as of the
close of the NYSE. The Fund will realize a gain or loss when the option
transaction expires or is exercised. When an option is exercised, the proceeds
on sales for a written call option, the purchase cost for a written put option
or the cost of a security for a purchased put or call option is adjusted by the
amount of premium received or paid. At April 30, 2009, and for the six months
then ended, the Fund had no outstanding option contracts.

FUTURES TRANSACTIONS
To gain exposure to or protect itself from market changes, the Fund may buy and
sell financial futures contracts traded on any U.S. or foreign exchange. The
Fund also may buy and write put and call options on these futures contracts.
Risks of entering into futures contracts and related options include the
possibility of an illiquid market and that a change in the value of the contract
or option may not correlate with changes in the value of the underlying
securities.

Futures and options on futures are valued daily based upon the last sale price
at the close of the market on the principal exchange on which they are traded.
Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by

- --------------------------------------------------------------------------------
                 THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT  25



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


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. At
April 30, 2009, the Fund had no outstanding futures contracts.

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS
Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate 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, 2009, foreign currency holdings consisted of
multiple denominations.

The Fund may enter into forward foreign currency 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 counterparty will not
complete its contract obligations.

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.


- --------------------------------------------------------------------------------
26  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



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


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

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of foreign currency
transactions and losses deferred due to wash sales. The character of
distributions made during the year from net investment income or net realized
gains may differ from their ultimate characterization for federal income tax
purposes. Also, due to the timing of dividend distributions, the fiscal year in
which amounts are distributed may differ from the year that the income or
realized gains (losses) were recorded by the Fund.

RECENT ACCOUNTING PRONOUNCEMENTS
The Fund has adopted FASB Staff Position No. 133-1 and FIN No. 45-4 (FSP FAS
133-1 and FIN 45-4), "Disclosures about Credit Derivatives and Certain
Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No.
45." The amendments to FSP FAS 133-1 and FIN 45-4 require enhanced disclosures
about a fund's derivatives and guarantees. Funds are required to provide
enhanced disclosures about (a) how and why a fund uses derivative instruments,
(b) how derivative instruments and related hedged items are accounted for under
SFAS 133 and its related interpretations, (c) how derivative instruments and
related hedged items affect a fund's financial position, financial performance,
and cash flows and (d) the current status of the payment/performance risk of the
credit derivative. The amendments to FSP FAS 133-1 and FIN 45-4 also require
additional disclosures about the current status of the payment/performance risk
of a guarantee. At April 30, 2009, the Fund did not own nor was it a party to
any credit derivative contracts within the scope of these amendments.

In March 2008, the FASB issued Statement of Financial Accounting Standards No.
161 (SFAS 161), "Disclosures about Derivative Instruments and Hedging
Activities -- an amendment of FASB Statement No. 133," which requires enhanced
disclosures about a fund's derivative and hedging activities. SFAS 161 is
effective for financial statements issued for fiscal years and interim periods
beginning after Nov. 15, 2008. As of April 30, 2009, management does not believe
the adoption of SFAS 161 will impact the financial statement amounts; however,
additional footnote disclosures may be required about the use of derivative
instruments and hedging items.

On April 9, 2009, the FASB issued Staff Position No. 157-4, "Determining Fair
Value When the Volume and Level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly"

- --------------------------------------------------------------------------------
                 THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT  27



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


(FSP 157-4). FSP 157-4 provides additional guidance for estimating fair value in
accordance with SFAS 157 when the volume and level of activity for the asset or
liability have significantly decreased. FSP 157-4 also requires additional
disaggregation of the current SFAS 157 required disclosures. FSP 157-4 is
effective for interim and annual reporting periods ending after June 15, 2009,
and shall be applied prospectively. Management is currently evaluating the
impact that the adoption of FSP 157-4 will have on the amounts and disclosures
within the Fund's financial statements.

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

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date 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

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Fund's average daily net assets that declines from 0.80%
to 0.57% annually as the Fund's assets increase. The fee may be adjusted upward
or downward by a performance incentive adjustment determined monthly by
measuring the percentage difference over a rolling 12-month period between the
annualized performance of one Class A share of the Fund and the annualized
performance of the Lipper European 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 management fee by $62,209 for the six months
ended April 30, 2009. The management fee for the six months ended April 30, 2009
was 1.01% of the Fund's average daily net assets, including the adjustment under
the terms of the performance incentive arrangement.

SUBADVISORY AGREEMENT
The Investment Manager has a Subadvisory Agreement with Threadneedle
International Limited (Threadneedle), an affiliate of the Investment Manager and


- --------------------------------------------------------------------------------
28  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



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


an indirect wholly-owned subsidiary of Ameriprise Financial, to subadvise the
assets of the Fund. The Investment Manager contracts with and compensates
Threadneedle to manage the investment of the Fund's assets.

ADMINISTRATIVE SERVICES FEES
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. The fee for the six months ended April 30, 2009 was
0.08% of the Fund's average daily net assets.

OTHER FEES
Other expenses are for, among other things, certain expenses of the Fund or the
Board including: Fund boardroom and office expense, employee compensation,
employee health and retirement benefits, and certain other expenses. Payment of
these Fund and Board expenses is facilitated by a company providing limited
administrative services to the Fund and the Board. For the six months ended
April 30, 2009, other expenses paid to this company were $270.

COMPENSATION OF BOARD MEMBERS
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.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains shareholder accounts and records. The Fund pays the Transfer
Agent an annual account-based fee at a rate equal to $19.50 for Class A, $20.50
for Class B and $20.00 for Class C for this service. The Fund also pays the
Transfer Agent an annual asset-based fee at a rate of 0.05% of the Fund's
average daily net assets attributable to Class R4 shares.

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

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

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

DISTRIBUTION FEES
The Fund has agreements with RiverSource Distributors, Inc. and RiverSource Fund
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. For Class B and Class C shares, up to 0.75% of the fee is
reimbursed for distribution expenses.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed expense") was approximately $193,000 and $12,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of April 30, 2009, and may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges received by the Distributor for distributing Fund shares were
$31,237 for Class A, $2,511 for Class B and $8 for Class C for the six months
ended April 30, 2009.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the six months ended April 30, 2009, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds*), including the adjustment under
the terms of a performance incentive arrangement, were as follows:

</Table>




- --------------------------------------------------------------------------------
30  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



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


The management fees waived/reimbursed at the Fund level were $57,613.

The Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses until Oct. 31, 2009, 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 the following percentage of the class average daily net assets:

<Table>

Class B.............................................  2.23
Class C.............................................  2.22
Class I.............................................  1.01
Class R4............................................  1.31
</Table>


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

CUSTODIAN FEES
Effective Dec. 15, 2008, the Fund pays custodian fees to JPMorgan Chase Bank,
N.A. For the period from Nov. 1, 2008 to Dec. 15, 2008, the Fund paid custodian
fees amounting to $1,000 to Ameriprise Trust Company, a subsidiary of Ameriprise
Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $46,575,771 and $54,964,634, respectively, for the six
months ended April 30, 2009. Realized gains and losses are determined on an
identified cost basis.

5. LENDING OF PORTFOLIO SECURITIES

Effective Dec. 1, 2008, the Fund has entered into a Master Securities Lending
Agreement ("the Agreement") with JPMorgan Chase Bank, National Association
("JPMorgan"). The Agreement authorizes JPMorgan as lending agent to lend
securities to authorized borrowers in order to generate additional income on
behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured
by cash or U.S. government securities equal to at least 100% of the market value
of the loaned securities. Any additional collateral required to maintain those
levels due to market fluctuations of the loaned securities is delivered the
following business day. Cash collateral received is invested by the lending
agent on behalf of the Fund into authorized investments pursuant to the
Agreement. The investments made with the cash collateral are listed in the
Portfolio of Investments. The values of such investments, and any uninvested
cash collateral balance, are disclosed in the Statement of Assets and
Liabilities along with the related obligation to return the collateral upon the
return of the securities loaned. At April 30, 2009, securities valued at
$9,293,835 were on loan, secured by cash collateral of $9,769,292 invested in
short-term securities or in cash equivalents.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Income of
$26,442 earned from securities lending from Dec. 1, 2008 through April 30, 2009
is included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

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

- --------------------------------------------------------------------------------
32  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



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



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

Prior to Dec. 1, 2008, the Investment Manager served as securities lending agent
for the Fund under the Securities Lending Agency Agreement. For the period from
Nov. 1, 2008 through Nov. 30, 2008, the Fund had no securities on loan.

6. 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. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash Fund aggregated $14,273,033 and $14,775,688, respectively, for the six
months ended April 30, 2009. The income distributions received with respect to
the Fund's investment in RiverSource Short-Term Cash Fund can be found in the
Statement of Operations and the Fund's invested balance in RiverSource Short-
Term Cash Fund at April 30, 2009, can be found in the Portfolio of Investments.

7. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility agreement, which is a
collective agreement between the Fund and certain other RiverSource funds,
severally and not jointly, permits collective borrowings up to $475 million. The
borrowers shall have the right, upon written notice to the Administrative Agent
to request an increase of up to $175 million in the aggregate amount of the
credit facility from new or existing lenders, provided that the aggregate amount
of the credit facility shall at no time exceed $650 million. Participation in
such increase by any existing lender shall be at such lender's sole discretion.
Interest is charged to each Fund based on its borrowings at a rate equal to the
federal funds rate plus 0.75%. Each borrowing under the credit facility matures
no later than 60 days after the date of borrowing. The Fund also pays a
commitment fee equal to its pro rata share of the amount of the credit facility
at a rate of 0.06% per annum, in addition to an upfront fee equal to its pro
rata share of 0.02% of the amount of the credit facility. The Fund had no
borrowings during the six months ended April 30, 2009.

8. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$45,298,067 at Oct. 31, 2008, that if not offset by capital gains will expire as
follows:

<Table>
<Caption>
    2009           2010          2011          2016
                                   
$19,489,378    $16,514,518    $5,021,215    $4,272,956
</Table>


It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires.

9. RISKS RELATING TO CERTAIN INVESTMENTS

FOREIGN/EMERGING MARKETS RISK
Investing in foreign securities may include certain risks and considerations not
typically associated with investing in U.S. securities, such as fluctuating
currency values and changing local and regional economic, political and social
conditions, which may result in greater market volatility. In addition, certain
foreign securities may not be as liquid as U.S. securities. Investing in
emerging markets may accentuate these risks.

10. 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 (the District Court). In response to defendants'
motion to dismiss the complaint, the District Court dismissed one of plaintiffs'
four claims and granted plaintiffs limited discovery. Defendants moved for
summary judgment in April 2007. Summary judgment was granted in the defendants'
favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth
Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8,
2009, the Eighth Circuit reversed summary judgment and remanded to the District
Court for further proceedings.

34  THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT



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


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

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

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

- --------------------------------------------------------------------------------
                 THREADNEEDLE EUROPEAN EQUITY FUND -- 2009 SEMIANNUAL REPORT  35



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


NYAG. Under the terms of the settlement, Seligman will pay $11.3 million to four
Seligman Funds. This settlement resolved all outstanding matters between the
Seligman Parties and the NYAG. In addition to the foregoing matter, the New York
staff of the SEC indicated in September 2005 that it was considering
recommending to the Commissioners of the SEC the instituting of a formal action
against Seligman and Seligman Advisors, Inc. relating to frequent trading in the
Seligman Funds. Seligman responded to the staff in October 2005 that it believed
that any action would be both inappropriate and unnecessary, especially in light
of the fact that Seligman had previously resolved the underlying issue with the
Independent Directors of the Seligman Funds and made recompense to the affected
Seligman Funds. There have been no further developments with the SEC on this
matter.

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

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

APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT ----------------------------------------------------------------------

RiverSource Investments, LLC ("RiverSource Investments" or the "investment
manager"), 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 Investments
provides investment advice and other services to the Fund and all funds in the
RiverSource Family of Funds (collectively, the "Funds"). In addition, under the
subadvisory agreement (the "Subadvisory Agreement") between RiverSource
Investments and Threadneedle International Limited (the "Subadviser"), the
Subadviser performs portfolio management and related services for the Fund.

On an annual basis, the Fund's Board of Directors (the "Board"), including the
independent Board members (the "Independent Directors"), considers renewal of
each of the IMS Agreement and the Subadvisory Agreement (together, the "Advisory
Agreements"). RiverSource Investments prepared detailed reports for the Board
and its Contracts Committee in March and April 2009, including reports based on
data provided by independent organizations to assist the Board in making these
determinations. In addition, throughout the year, the Board (or its committees)
reviews information prepared by RiverSource Investments addressing the services
RiverSource Investments provides and Fund performance. The Board accords
particular weight to the work, deliberations and conclusions of the Contracts,
Investment Review and Compliance Committees in determining whether to continue
the Advisory Agreements. At the April 7-8, 2009 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 and subadvisory 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 each of the Advisory Agreements.

Nature, Extent and Quality of Services Provided by RiverSource Investments and
the Subadviser:  The Board analyzed various reports and presentations it had
received detailing the services performed by RiverSource Investments and the
Subadviser, as well as their expertise, resources and capabilities. The Board
specifically considered many developments during the past year concerning the
services provided by RiverSource Investments, including, in particular, the
continued investment in, and resources dedicated to, the Fund's operations, most
notably, the large investment made in the acquisition of J. & W. Seligman & Co.
Incorporated, including its portfolio management operations, personnel and
infrastructure (including the addition of two new offices in New York City and

Palo Alto). Further, in connection with the Board's evaluation of the overall
package of services provided by RiverSource Investments, the Board considered
the quality of the administrative and transfer agency services provided by
RiverSource Investments' affiliates to the Fund. The Board also reviewed the
financial condition of RiverSource Investments (and its affiliates including the
Subadviser), and each entity's ability to carry out its responsibilities under
the Advisory Agreements. Further, the Board considered RiverSource Investments'
ability to retain key personnel and its expectations in this regard. 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 Investments). The Board concluded that the services being performed
under the Advisory Agreements were of a reasonably high quality, particularly in
light of recent market conditions.

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 concluded that RiverSource Investments and
its affiliates, including the Subadviser, 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, recent Fund inflows (and outflows) and
a comparison of the Fund's net assets from December 2007 to December 2008. The
Board observed that the Fund's investment performance met expectations.
Additionally, the Board reviewed the performance of the Subadviser and
RiverSource Investments' processes for monitoring the Subadviser. The Board
considered, in particular, management's rationale for recommending the continued
retention of the Subadviser.

Comparative Fees, Costs of Services Provided and the Profits Realized By
RiverSource Investments 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 Investments' 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 (excluding the effect of a performance incentive
adjustment, if applicable), 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. The Board also
considered the Fund's performance incentive adjustment and noted its continued
appropriateness.

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

APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT (continued) ----------------------------------------------------------

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 8, 2009,
the Board, including all of the Independent Directors, approved the renewal of
each of the Advisory Agreements for an additional annual period.

PROXY VOTING  ------------------------------------------------------------------

The policy of the Board is to vote the proxies of the companies in which the
Fund holds investments consistent with the procedures as stated in the Statement
of Additional Information (SAI). You may obtain a copy of the SAI without charge

    during the fund's most recently completed fiscal year, and have not been
    adjusted for current asset levels, including any decrease or increase in
    assets, which, if adjusted, would result in expense ratios that are higher
    or lower, respectively, than those that are expressed herein. Any fee

financial reporting and accounting standards and oversight. Risks are
particularly significant in emerging markets.

        THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT  7



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 expense ratio of each of the acquired funds as of the acquired fund's
most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2009.

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.

FAIR VALUE MEASUREMENTS


Statement of Financial Accounting Standards No. 157 (SFAS 157) seeks to
implement more uniform reporting relating to the fair valuation of securities
for financial statement purposes. Mutual funds are required to implement the
requirements of this standard for fiscal years beginning after Nov. 15, 2007.
While uniformity of presentation is the objective of the standard, it is likely
that there may be a range of practices utilized and it may be some period of
time before industry practices become more uniform. For this reason care should
be exercised in interpreting this information and/or using it for comparison
with other mutual funds.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below:

     - Level 1 -- quoted prices in active markets for identical securities

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

     - Level 3 -- significant unobservable inputs (including the Fund's own
       assumptions in determining the fair value of investments)

Observable inputs are those based on market data obtained from sources
independent of the Fund, and unobservable inputs reflect the Fund's own
assumptions based on the best information available. The input levels are not
necessarily an indication of the risk or liquidity associated with investments
at that level. Non-U.S. equity securities actively traded in foreign markets may
be reflected in Level 2 despite the availability of closing prices, because the
Fund evaluates and determines whether those closing prices reflect fair value at
the close of the NYSE or require adjustment, as described in Note 1 to the
financial statements -- Valuation of securities.

The following table is a summary of the inputs used to value the Fund's
investments as of April 30, 2009:

(UNAUDITED AS TO APRIL 30, 2009)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Threadneedle International Opportunity Fund (the Fund) is a series of
RiverSource International Series, Inc. and is registered under the Investment
Company Act of 1940 (as amended) as a diversified, open-end management
investment company. RiverSource International Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Board of Directors (the Board). The Fund invests
primarily in equity securities of foreign issuers that are believed to offer
strong growth potential.

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

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

At April 30, 2009, RiverSource Investments, LLC (RiverSource Investments or the
Investment Manager) and the RiverSource affiliated funds-of-funds owned 100% of
Class I shares and the Investment Manager owned 100% of Class R3 and Class R5
shares. At April 30, 2009, the Investment Manager and the RiverSource affiliated
funds-of-funds owned approximately 28% of the total outstanding Fund shares.

All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration services fees) differ among classes. Income, expenses
(other than class specific expenses) and realized and unrealized gains or losses
on investments are allocated to each class of shares based upon its relative net
assets.

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,

- --------------------------------------------------------------------------------
32  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT



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


liabilities and contingent assets and liabilities) that could differ from actual
results.

VALUATION OF SECURITIES
Effective Nov. 1, 2008, the Fund adopted Statement of Financial Accounting
Standards No. 157 "Fair Value Measurements" (SFAS 157). SFAS 157 establishes an
authoritative definition of fair value, sets out a hierarchy for measuring fair
value, and requires additional disclosures about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported in
the Statement of Operations for a fiscal period. There was no impact to the
Fund's net assets or results of operations upon adoption. The fair valuation
measurements disclosure can be found following the Notes to Portfolio of
Investments.

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.
When market quotes are not readily available, the pricing service, in
determining fair values of debt securities, takes into consideration such
factors as current quotations by broker/dealers, coupon, maturity, quality, type
of issue, trading characteristics, and other yield and risk factors it deems
relevant in determining valuations. Foreign securities are valued based on
quotations from the principal market in which such securities are normally
traded. The procedures adopted by the Board generally contemplate the use of
fair valuation in the event that price quotations or valuations are not readily
available, price quotations or valuations from other sources are not reflective
of market value and thus deemed unreliable, or a significant event has occurred
in relation to a security or class of securities (such as foreign securities)
that is not reflected in price quotations or valuations from other sources. A
fair value price is a good faith estimate of the value of a security at a given
point in time.

Many securities markets and exchanges outside the U.S. close prior to the close
of the New York Stock Exchange (NYSE) and therefore the closing prices for
securities in such markets or on such exchanges may not fully reflect events
that occur after such close but before the close of the NYSE, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial, Inc. (Ameriprise
Financial), parent company of the Investment Manager, as administrator to the
Fund, will fair value foreign securities pursuant to procedures adopted by the
Board, including utilizing a third party pricing service to determine these fair
values. These

- --------------------------------------------------------------------------------
       THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT  33



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


procedures take into account multiple factors, including movements in the U.S.
securities markets, to determine a good faith estimate that reasonably reflects
the current market conditions as of the close of the NYSE.

Short-term securities maturing in more than 60 days from the valuation date are
valued at the market price or approximate market value based on current interest
rates; those maturing in 60 days or less are valued at amortized cost, which
approximates fair value.

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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. Option
contracts, including OTC option contracts, with no readily available market
value are valued using quotations obtained from independent brokers as of the
close of the NYSE. The Fund will realize a gain or loss when the option
transaction expires or is exercised. When an option is exercised, the proceeds
on sales for a written call option, the purchase cost for a written put option
or the cost of a security for a purchased put or call option is adjusted by the
amount of premium received or paid. At April 30, 2009, and for the six months
then ended, the Fund had no outstanding option contracts.

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

- --------------------------------------------------------------------------------
34  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT



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


illiquid market and that a change in the value of the contract or option may not
correlate with changes in the value of the underlying securities.

Futures and options on futures are valued daily based upon the last sale price
at the close of the market on the principal exchange on which they are traded.
Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires. At April 30, 2009, the Fund had no outstanding futures contracts.

FOREIGN CURRENCY TRANSLATIONS AND FORWARD FOREIGN CURRENCY CONTRACTS
Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate 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, 2009, foreign currency holdings consisted of
multiple denominations.

The Fund may enter into forward foreign currency 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 counterparty will not
complete its contract obligations.

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.

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

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.

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

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

RECENT ACCOUNTING PRONOUNCEMENTS
The Fund has adopted FASB Staff Position No. 133-1 and FIN No. 45-4 (FSP FAS
133-1 and FIN 45-4), "Disclosures about Credit Derivatives and Certain
Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No.
45." The amendments to FSP FAS 133-1 and FIN 45-4 require enhanced disclosures
about a fund's derivatives and guarantees. Funds are required to provide
enhanced disclosures about (a) how and why a fund uses derivative instruments,
(b) how derivative instruments and related hedged items are accounted for under
SFAS 133 and its related interpretations, (c) how derivative instruments and
related hedged items affect a fund's financial position, financial performance,
and cash flows and (d) the current status of the payment/performance risk of the
credit derivative. The amendments to FSP FAS 133-1 and FIN 45-4 also require
additional disclosures about the current status of the payment/performance risk
of a guarantee.

In March 2008, the FASB issued Statement of Financial Accounting Standards No.
161 (SFAS 161), "Disclosures about Derivative Instruments and Hedging
Activities -- an amendment of FASB Statement No. 133," which requires enhanced
disclosures about a fund's derivative and hedging activities. SFAS 161 is
effective for financial statements issued for fiscal years and interim periods
beginning after Nov. 15, 2008. As of April 30, 2009, management does not believe
the adoption of SFAS 161 will impact the financial statement amounts;

- --------------------------------------------------------------------------------
36  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT



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



however, additional footnote disclosures may be required about the use of
derivative instruments and hedging items.

On April 9, 2009, the FASB issued Staff Position No. 157-4, "Determining Fair
Value When the Volume and Level of Activity for the Asset or Liability Have
Significantly Decreased and Identifying Transactions That Are Not Orderly" (FSP
157-4). FSP 157-4 provides additional guidance for estimating fair value in
accordance with SFAS 157 when the volume and level of activity for the asset or
liability have significantly decreased. FSP 157-4 also requires additional
disaggregation of the current SFAS 157 required disclosures. FSP 157-4 is
effective for interim and annual reporting periods ending after June 15, 2009,
and shall be applied prospectively. Management is currently evaluating the
impact that the adoption of FSP 157-4 will have on the amounts and disclosures
within the Fund's financial statements.

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

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date 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

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Fund's average daily net assets that declines from 0.80%
to 0.57% annually as the Fund's assets increase. The fee may be adjusted upward
or downward by a performance incentive adjustment determined monthly by
measuring the percentage difference over a rolling 12-month period between the
annualized performance of one Class A share of the Fund and the annualized
performance of the Lipper International Large-Cap Core Funds Index. In certain
circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year. If the performance difference is less than 0.50%,
the adjustment will be zero. The adjustment increased the management fee by
$196,273 for the six months April 30, 2009. The management fee for the six

- --------------------------------------------------------------------------------
       THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT  37



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

months April 30, 2009 was 0.91% of the Fund's average daily net assets,
including the adjustment under the terms of the performance incentive
arrangement.

SUBADVISORY AGREEMENT
The Investment Manager has a Subadvisory Agreement with Threadneedle
International Limited (Threadneedle), an affiliate of the Investment Manager and
an indirect wholly-owned subsidiary of Ameriprise Financial, to subadvise the
asset of the Fund. The Investment Manager contracts with and compensates
Threadneedle to manage the investment of the Fund's assets.

ADMINISTRATIVE SERVICES FEES
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. The fee for the six months April 30, 2009 was 0.08% of
the Fund's average daily net assets.

OTHER FEES
Other expenses are for, among other things, certain expenses of the Fund or the
Board including: Fund boardroom and office expense, employee compensation,
employee health and retirement benefits, and certain other expenses. Payment of
these Fund and Board expenses is facilitated by a company providing limited
administrative services to the Fund and the Board. For the six months April 30,
2009, other expenses paid to this company were $1,361.

COMPENSATION OF BOARD MEMBERS
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.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains shareholder accounts and records. The Fund pays the Transfer
Agent an annual account-based fee at a rate equal to $19.50 for Class A, $20.50
for Class B and $20.00 for Class C for this service. The Fund also pays the
Transfer Agent an annual asset-based fee at a rate of 0.05% of the Fund's
average daily net assets attributable to Class R2, Class R3, Class R4 and Class
R5 shares.


- --------------------------------------------------------------------------------
38  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT



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


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

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

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

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed expense") was approximately $857,000 and $31,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of April 30, 2009, and may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges received by the Distributor for distributing Fund shares were
$79,392 for Class A, $10,531 for Class B and $152 for Class C for the six months
ended April 30, 2009.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the six months April 30, 2009, the Investment Manager and its affiliates
waived/reimbursed certain fees and expenses such that net expenses (excluding
fees and expenses of acquired funds*), including the adjustment under the terms
of a performance incentive arrangement, were as follows:

<Table>
                                                   
Class R2............................................  1.77%
Class R3............................................  1.46
Class R4............................................  1.30
</Table>




- --------------------------------------------------------------------------------
       THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT  39



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

The waived/reimbursed fees and expenses for plan administration services fee at
the class level were as follows:

<Table>
                                                   
Class R2............................................  $ 2
Class R3............................................    2
Class R4............................................   88
</Table>


The Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses until Oct. 31, 2009, 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 the following percentage of the class average daily net assets:

<Table>
                                                   
Class R4............................................  1.30%
</Table>


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

CUSTODIAN FEES
Effective Dec. 15, 2008, the Fund pays custodian fees to JPMorgan Chase Bank,
N.A. For the period from Nov. 1, 2008 to Dec. 15, 2008, the Fund paid custodian
fees amounting to $4,198 to Ameriprise Trust Company, a subsidiary of Ameriprise
Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $155,512,219 and $159,337,140 respectively, for the six
months ended April 30, 2009. Realized gains and losses are determined on an
identified cost basis.

5. LENDING OF PORTFOLIO SECURITIES

Effective Dec. 1, 2008, the Fund has entered into a Master Securities Lending
Agreement ("the Agreement") with JPMorgan Chase Bank, National Association
("JPMorgan"). The Agreement authorizes JPMorgan as lending agent to lend
securities to authorized borrowers in order to generate additional income on
behalf of the Fund. Pursuant to the Agreement, the securities loaned are secured
by cash or U.S. government securities equal to at least 100% of the market value
of the loaned securities. Any additional collateral required to maintain those
levels due to market fluctuations of the loaned securities is delivered the
following business day. Cash collateral received is invested by the lending
agent on behalf of the Fund into authorized investments pursuant to the
Agreement. The investments made with the cash collateral are listed in the
Portfolio of Investments. The value of such investments, including any
uninvested cash collateral balances, are disclosed in the Statement of Assets
and Liabilities along with the related obligation to return the collateral upon
return of the securities loaned. At April 30, 2009, securities valued at
$47,617,881 were on loan, secured

- --------------------------------------------------------------------------------
       THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT  41



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


by cash collateral of $49,578,792 invested in short-term securities or in cash
equivalents.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Income of
$102,588 earned from securities lending from Dec. 1, 2008 through April 30, 2009
is included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

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

Prior to Dec. 1, 2008, the Investment Manager served as securities lending agent
for the Fund under the Securities Lending Agency Agreement. For the period from
Nov. 1, 2008 through Nov. 30, 2008, the Fund had no securities on loan.

6. 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. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash Fund aggregated $69,240,410 and $66,314,596, respectively, for the six
months April 30, 2009. The income distributions received with respect to the
Fund's investment in RiverSource Short-Term Cash Fund can be found in the
Statement of Operations and the Fund's invested balance in RiverSource Short-
Term Cash Fund at April 30, 2009, can be found in the Portfolio of Investments.

7. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (JPMCB) (the Administrative Agent), whereby the
Fund may borrow for the temporary funding of shareholder redemptions or for
other temporary or emergency purposes. The credit facility agreement, which is a
collective agreement between the Fund and certain other

- --------------------------------------------------------------------------------
42  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT



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



RiverSource funds, severally and not jointly, permits collective borrowings up
to $475 million. The borrowers shall have the right, upon written notice to the
Administrative Agent to request an increase of up to $175 million in the
aggregate amount of the credit facility from new or existing lenders, provided
that the aggregate amount of the credit facility shall at no time exceed $650
million. Participation in such increase by any existing lender shall be at such
lender's sole discretion. Interest is charged to each Fund based on its
borrowings at a rate equal to the federal funds rate plus 0.75%. Each borrowing
under the credit facility matures no later than 60 days after the date of
borrowing. The Fund also pays a commitment fee equal to its pro rata share of
the amount of the credit facility at a rate of 0.06% per annum, in addition to
an upfront fee equal to its pro rata share of 0.02% of the amount of the credit
facility. The Fund had no borrowings during the six months ended April 30, 2009.

8. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$246,866,293 at Oct. 31, 2008, that if not offset by capital gains will expire
as follows:

<Table>
<Caption>
    2009            2010           2011           2016
                                     
$137,301,860    $59,231,998    $38,262,972    $12,069,463
</Table>


It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires.

9. RISKS RELATING TO CERTAIN INVESTMENTS

FOREIGN/EMERGING MARKETS RISK
Investing in foreign securities may include certain risks and considerations not
typically associated with investing in U.S. securities, such as fluctuating
currency values and changing local and regional economic, political and social
conditions, which may result in greater market volatility. In addition, certain
foreign securities may not be as liquid as U.S. securities. Investing in
emerging markets may accentuate these risks.

10. 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

- --------------------------------------------------------------------------------
       THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT  43



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


purport to bring the action derivatively on behalf of those funds under the
Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid
to the defendants by the funds for investment advisory and administrative
services are excessive. The plaintiffs seek remedies including restitution and
rescission of investment advisory and distribution agreements. The plaintiffs
voluntarily agreed to transfer this case to the United States District Court for
the District of Minnesota (the District Court). In response to defendants'
motion to dismiss the complaint, the District Court dismissed one of plaintiffs'
four claims and granted plaintiffs limited discovery. Defendants moved for
summary judgment in April 2007. Summary judgment was granted in the defendants'
favor on July 9, 2007. The plaintiffs filed a notice of appeal with the Eighth
Circuit Court of Appeals (the Eighth Circuit) on August 8, 2007. On April 8,
2009, the Eighth Circuit reversed summary judgment and remanded to the District
Court for further proceedings.

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

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

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



arrangements to its clients and to shareholders of the Seligman Funds. Seligman
also provided information concerning mutual fund trading practices to the SEC
and the Office of the Attorney General of the State of New York (NYAG).

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

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

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

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.

APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT ----------------------------------------------------------------------

RiverSource Investments, LLC ("RiverSource Investments" or the "investment
manager"), 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 Investments
provides investment advice and other services to the Fund and all funds in the
RiverSource Family of Funds (collectively, the "Funds"). In addition, under the
subadvisory agreement (the "Subadvisory Agreement") between RiverSource
Investments and Threadneedle International Limited (the "Subadviser"), the
Subadviser performs portfolio management and related services for the Fund.

On an annual basis, the Fund's Board of Directors (the "Board"), including the
independent Board members (the "Independent Directors"), considers renewal of
each of the IMS Agreement and the Subadvisory Agreement (together, the "Advisory
Agreements"). RiverSource Investments prepared detailed reports for the Board
and its Contracts Committee in March and April 2009, including reports based on
data provided by independent organizations to assist the Board in making these
determinations. In addition, throughout the year, the Board (or its committees)
reviews information prepared by RiverSource Investments addressing the services
RiverSource Investments provides and Fund performance. The Board accords
particular weight to the work, deliberations and conclusions of the Contracts,
Investment Review and Compliance Committees in determining whether to continue
the Advisory Agreements. At the April 7-8, 2009 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 and subadvisory 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.

Nature, Extent and Quality of Services Provided by RiverSource Investments and
the Subadviser:  The Board analyzed various reports and presentations it had
received detailing the services performed by RiverSource Investments and the
Subadviser, as well as their expertise, resources and capabilities. The Board
specifically considered many developments during the past year concerning the
services provided by RiverSource Investments, including, in particular, the
continued investment in, and resources dedicated to, the Fund's operations, most
notably, the large investment made in the acquisition of J. & W. Seligman & Co.
Incorporated, including its portfolio management operations, personnel and
infrastructure (including the addition of two new offices in New York City and
Palo Alto). Further, in connection with the Board's evaluation of the overall

- --------------------------------------------------------------------------------
       THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT  47



APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT (continued) ----------------------------------------------------------


package of services provided by RiverSource Investments, the Board considered
the quality of the administrative and transfer agency services provided by
RiverSource Investments' affiliates to the Fund. The Board also reviewed the
financial condition of RiverSource Investments (and its affiliates including the
Subadviser), and each entity's ability to carry out its responsibilities under
the Advisory Agreements. Further, the Board considered RiverSource Investments'
ability to retain key personnel and its expectations in this regard. 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 Investments). The Board concluded that the services being performed
under the Advisory Agreements were of a reasonably high quality, particularly in
light of recent market conditions.

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 concluded that RiverSource Investments and
its affiliates, including the Subadviser, 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, recent Fund inflows (and outflows) and
a comparison of the Fund's net assets from December 2007 to December 2008. The
Board observed that the Fund's investment performance met expectations.
Additionally, the Board reviewed the performance of the Subadviser and
RiverSource Investments' processes for monitoring the Subadviser. The Board
considered, in particular, management's rationale for recommending the continued
retention of the Subadviser.

Comparative Fees, Costs of Services Provided and the Profits Realized By
RiverSource Investments 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

- --------------------------------------------------------------------------------
48  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2009 SEMIANNUAL REPORT



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


funds in its peer group, as well as data showing the Fund's contribution to
RiverSource Investments' profitability. They also reviewed information in the
report comparing the fee charged to the Fund to fees charged to other client
accounts of the investment manager (or Subadviser) (with similar investment
strategies to those of the Fund).

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 (excluding the effect of a performance incentive
adjustment, if applicable), with few exceptions, is at or below the median
expense ratio of funds in the same comparison group). The Board took into
account that the Fund's total expense ratio (after considering proposed expense
caps/waivers) was slightly below the peer group's median expense ratio shown in
the reports. The Board also considered the Fund's performance incentive
adjustment and noted its continued appropriateness.

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

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

APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT (continued) ----------------------------------------------------------


In reaching this conclusion, no single factor was determinative. On April 8,
2009, the Board, including all of the Independent Directors, approved the
renewal of the Advisory Agreements for an additional annual period.

PROXY VOTING -------------------------------------------------------------------

The policy of the Board is to vote the proxies of the companies in which the
Fund holds investments consistent with the procedures as stated in the Statement
