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

The 5.75% sales charge applicable to Class A shares of the Fund is not reflected

MANAGER COMMENTARY (continued) -------------------------------------------------


SIGNIFICANT PERFORMANCE FACTORS
It would be putting it mildly to say that international equities experienced
both a sizable correction and heightened volatility during the annual period.
Strains in the financial markets that were first made visible in the U.S.
subprime mortgage industry continued to build. Ultimately, such pressures
resulted in the collapse of the global credit markets, as the balance sheets of
banks worldwide imploded and trust between and among financial institutions
evaporated. Adding to the turmoil were prices of major commodities, including
crude oil, which reached record highs before retreating significantly near the
end of the annual period. This loss of upward commodity price momentum weighed
particularly heavily on the materials and energy sectors of the international
equity markets.

The Fund's performance was driven primarily by the performance of the three
quantitative investment models -- momentum, value and quality-adjusted
value -- that we employ in selecting stocks for the Fund's portfolio. The three
models choose the international stocks for the portfolio, and we then weight the
stocks chosen. During the reporting period, all three quantitative models
underperformed the MSCI EAFE Index. On a relative basis, the momentum model
underperformed least, while both the quality-adjusted value and value models
performed similarly to each other and more than twice as poorly as momentum.

Though disappointing, our research indicates that periods of correlated
underperformance, which occasionally occur, are historically short-lived. Such
instances in no way invalidate our belief that the style diversification
provided by the three very different quantitative models may be a significant
investment advantage over time.

In seeking to manage the risks associated with international equity investing,
we use a proprietary risk management system that helps us manage the Fund's
exposure to several key factors, including country, region, industry, sector,
market capitalization and portfolio turnover. We also use quantitative asset
allocation models to determine the mix between developed international markets
and emerging markets. Throughout the period, we used these and other techniques
in our effort to reduce the overall expected risk of the portfolio.

From a sector perspective, only the Fund's sizable allocation to energy
contributed to relative results. All other sector positioning detracted, with
stock selection in financials hurting most. To a lesser degree, having only a
modest allocation to the strong-performing health care sector and a more sizable
allocation to the weaker materials sector also hurt performance, as did stock
selection within each of these sectors.

All of the regions that the Fund invests in generated negative returns.
Performance was hurt most by stock selection in the U.K; stock selection in
Europe overall also detracted. Within Europe, stock selection in Germany, Italy
and Denmark actually contributed to Fund performance as did somewhat sizable
allocations to Germany and Denmark. However, stock selection in France
detracted. Having only a modest exposure to

MANAGER COMMENTARY (continued) -------------------------------------------------



Japan, which declined but outpaced the MSCI EAFE Index, also hurt, along with
security selection there. Finally, declining commodity prices particularly
impacted the resource-rich Pacific (excluding Japan) region -- having a
significant exposure to this region detracted from Fund performance.

From a market capitalization perspective, the Fund's emphasis on large-cap
stocks and its more modest exposure to small-cap stocks helped. Individual
stocks that contributed most to the Fund's return were German auto manufacturer
VOLKSWAGEN STAMM, selected by all three of the Fund's quantitative investment
models; Hong Kong electric utility CLP HOLDINGS, chosen by the quality-adjusted
value and value models; and electric utility HONGKONG ELECTRIC HOLDINGS,
selected by all three models. Even in a broad market decline, some individual
stocks performed well. These stocks actually managed to generate gains in what
can only be described as a dismal international equity market during the annual
period.

Stocks that detracted from the Fund's results most were the ROYAL BANK OF
SCOTLAND GROUP, chosen by the quality-adjusted value and value models; U.K.
commercial bank BARCLAYS, selected by the quality-adjusted value and value
models; U.K. diversified metals producer RIO TINTO, selected by all three
models; Netherlands insurance company ING GROEP, chosen by the quality-adjusted
value and value models and U.K. commercial bank HBOS GROUP, also a quality-
adjusted value and value model pick.

As a result of consistent application of our disciplined investment process, the
Fund's modest allocations to financials, utilities and health care increased
somewhat. The Fund's exposure to industrials and information technology
decreased.

The Fund's modest exposure to Japan was increased slightly. We decreased the
Fund's sizable allocation to the Pacific (excluding Japan) region, particularly
Australia. We increased the Fund's already significant position in the U.K.
Within Europe, we added to the Fund's exposure to Italy and Switzerland, and
moderately decreased its allocations to Germany and Spain.

10  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT



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


Toward the end of the annual period, we virtually eliminated the Fund's exposure
to emerging market equities. This move proved prudent, as emerging markets
subsequently underperformed. However, the Fund's emerging market equity
positions still detracted from its performance during the time they were held in
the portfolio.

OUR FUTURE STRATEGY
While the annual period was clearly a most challenging one, it did not alter our
conviction in our process. Indeed, our in-depth research continues to uphold the
validity of our process for investors with a long-term perspective. Certainly,
our quantitative investment models will not produce positive returns for every
reporting period, but the models are operating as designed over time. That said,
we believe that during times like this that the consistent use of multiple
investment disciplines is more critical than ever if we are to serve the Fund
well over the long term.

Employing style diversification remains a key aspect of our management process.
We continue to believe that the combination of our three well-tested
quantitative models should help us deliver value over extended periods of time.
We are equally convinced of the merit of our multifaceted, disciplined approach
to managing risk in the portfolio. We will continue our strategy of monitoring
weightings as a risk control so that no individual security, industry, sector,
country or region becomes too large within the Fund's portfolio. We also intend
to continue to employ the macroscopic aspects of our rigorous risk controls,
including constraints on market capitalization, price, quality, turnover,
transaction costs and more, with a goal of identifying high quality portfolio
holdings.

THE FUND'S LONG-TERM PERFORMANCE -----------------------------------------------

The chart on the facing page illustrates the total value of an assumed $10,000
investment in RiverSource Disciplined International Equity Fund Class A shares
(from 6/1/06 to 10/31/08)* as compared to the performance of two widely cited
performance indices, the Morgan Stanley Capital International (MSCI) EAFE Index
and the Lipper International Large-Cap Core Funds Index. In comparing the Fund's
Class A shares to these indices, you should take into account the fact that the
Fund's performance reflects the maximum sales charge of 5.75%, while such
charges are not reflected in the performance of the indices. Returns for the
Fund include the reinvestment of any distribution paid during each period.

The performance information shown represents past performance and is not a
guarantee of future results. The table below and the chart on the facing page do
not reflect the deduction of taxes that a shareholder would pay on fund
distributions or the redemption of fund shares. The investment return and
principal value of your investment will fluctuate so that your shares, when
redeemed, may be worth more or less than their original cost. Current
performance may be lower or higher than the performance information shown. You
may obtain performance information current to the most recent month-end by
contacting your financial institution or visiting riversource.com/funds. Also
see "Past Performance" in the Fund's current prospectus.

     RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT  15



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 indicated and held until Oct. 31, 2008.

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.

40  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT



NOTES TO FINANCIAL STATEMENTS --------------------------------------------------

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 R2, Class R3 and Class R5 shares became available effective
   Aug. 1, 2008.

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

At Oct. 31, 2008, RiverSource Investments, LLC (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,

- --------------------------------------------------------------------------------
     RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT  41



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


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

VALUATION OF SECURITIES
All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
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 and therefore the closing prices for securities
in such markets or on such exchanges may not fully reflect events that occur
after such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial, 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 New
York Stock Exchange.

Short-term securities maturing in more than 60 days from the valuation date are
valued at the market price or approximate market value based on current interest
rates; those maturing in 60 days or less are valued at amortized cost, 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 New York Stock Exchange. The Fund will realize a gain or loss when
the option transaction expires or closes. When an option is exercised, the
proceeds on sales for a written call option, the purchase cost for a written put
option or the cost of a security for a purchased put or call option is adjusted
by the amount of premium received or paid. At Oct. 31, 2008, and for the year
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 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

- --------------------------------------------------------------------------------
     RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT  43



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



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. At Oct. 31, 2008, foreign currency holdings consisted of
primarily Australian Dollars.

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 Oct. 31, 2008, the Fund had no outstanding
forward foreign currency contracts.

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

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

Financial Accounting Standards Board (FASB) Interpretation 48 (FIN 48),
"Accounting for Uncertainty in Income Taxes," clarifies the accounting for
uncertainty in income taxes recognized in accordance with FASB Statement 109,

- --------------------------------------------------------------------------------
44  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT



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



"Accounting for Income Taxes." FIN 48 provides guidance for how uncertain tax
positions should be recognized, measured, presented and disclosed in the
financial statements. 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.

On the Statement of Assets and Liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been increased by $325,082
and accumulated net realized loss has been increased by $325,082.

The tax character of distributions paid for the years indicated is as follows:

Activities -- an amendment of FASB Statement No. 133," which requires enhanced
disclosures about a fund's derivative and hedging activities. 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, and (c) how
derivative instruments and related hedged items affect a fund's financial
position, financial performance, and cash flows. SFAS 161 is effective for
financial statements issued for periods beginning after Nov. 15, 2008. As of
Oct. 31, 2008, 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 Sept. 20, 2006, the FASB released Statement of Financial Accounting Standards
No. 157 "Fair Value Measurements" (SFAS 157). SFAS 157 establishes an
authoritative definition of fair value, sets out a 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. The application of SFAS 157
will be effective for the Fund's fiscal year beginning Nov. 1, 2008. The
adoption of SFAS 157 is not anticipated to have a material impact on the

- --------------------------------------------------------------------------------
46  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT



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



Fund's financial statements; however, additional disclosures will be required
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.

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 decreased the management fee by
$213,635 for the year ended Oct. 31, 2008. The management fee for the year ended
Oct. 31, 2008 was 0.75% 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 year ended Oct. 31, 2008 was 0.08% of
the Fund's average daily net assets.

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


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 year ended Oct. 31,
2008, other expenses paid to this company were $3,700.

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

Under a Deferred Compensation Plan (the Plan), non-interested board members may
defer receipt of their compensation. Deferred amounts are treated as though
equivalent dollar amounts had been invested in shares of the Fund or other
RiverSource funds. The Fund's liability for these amounts is adjusted for market
value changes and remains in the Fund until distributed in accordance with the
Plan.

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 on the Statement of Operations.

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

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Distributors, Inc. (the Distributor)
for distribution and shareholder services. Under a Plan and Agreement of

- --------------------------------------------------------------------------------
48  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT



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


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 $479,000 and $13,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of Oct. 31, 2008, 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
$159,312 for Class A, $8,969 for Class B and $411 for Class C for the year ended
Oct. 31, 2008.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the year ended Oct. 31, 2008, 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............................................  1.44%
Class R3............................................  1.19
Class R4............................................  0.95
</Table>


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

Class R2...........................................  $  3
Class R3...........................................     3
Class R4...........................................   244
</Table>


Under an agreement which was effective until Oct. 31, 2008, the Investment
Manager and its affiliates contractually agreed to waive certain fees and
expenses such that net expenses (excluding fees and expenses of acquired
funds*), before

- --------------------------------------------------------------------------------
     RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT  49



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


giving effect to any performance incentive adjustment, would not exceed the
following percentage of the Fund's average daily net assets:

<Table>
                                                   
Class A.............................................  1.50%
Class B.............................................  2.26
Class C.............................................  2.26
Class I.............................................  1.12
Class R2............................................  1.92
Class R3............................................  1.67
Class R4............................................  1.37
Class R5............................................  1.17
Class W.............................................  1.57
</Table>


Effective Nov. 1, 2008, 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 Fund's 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.

EARNINGS AND BANK FEE CREDITS
During the year ended Oct. 31, 2008, the Fund's custodian and transfer agency
fees were reduced by $1,087 as a result of earnings and bank fee credits from
overnight cash balances. The Fund pays custodian fees 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 $661,748,768 (including $192,198,944 from RiverSource
International Equity Fund that was acquired in the fund merger as described in
Note 7) and $407,007,626, respectively, for the year ended Oct. 31, 2008.
Realized gains and losses are determined on an identified cost basis.

6. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or emergency
purposes. The credit facility became effective on Oct. 16, 2008, replacing a
prior credit facility. 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 year ended Oct. 31, 2008.

Under the prior credit facility which was effective until Oct. 15, 2008, the
Fund had entered into a revolving credit facility with a syndicate of banks
headed by JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund was permitted to
borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility agreement, which was a
collective agreement between the Fund and certain other RiverSource funds,
severally and not jointly, permitted collective borrowings up to $500 million.
Interest was charged to each Fund based on its borrowings at a rate equal to the
federal funds rate plus 0.30%. Each borrowing under the credit facility matured
no later than 60 days after the date of borrowing. The Fund also paid a
commitment fee equal to its pro rata share of the amount of the credit facility
at a rate of 0.06% per annum.

7. 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.


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

8. 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.

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

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);

- --------------------------------------------------------------------------------
54  RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND -- 2008 ANNUAL REPORT



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



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 2005, the
New York staff of the SEC indicated that it was considering recommending to the
Commissioners of the SEC the instituting of a formal action against Seligman and
the distributor of the Seligman Funds, 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.

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc., Seligman Data Corp. (transfer
agent for the Seligman Funds) and Brian T. Zino (collectively, the Seligman
Parties), alleging, in substance, that, in addition to the four arrangements
noted above, the Seligman Parties permitted other persons to engage in frequent
trading and, as a result, the prospectus disclosure used by the registered
investment companies 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. The NYAG is seeking damages of at least
$80 million and restitution, disgorgement, penalties and costs and injunctive
relief. The Seligman Parties answered the complaint in December 2006 and believe
that the claims are without merit. Any resolution of these matters may include
the relief noted above or other sanctions or changes in procedures. Any damages
would be paid by Seligman and not by the Seligman Funds. If the NYAG obtains
injunctive relief, Seligman and its affiliates could, in the absence of the SEC
in its discretion granting exemptive relief, be enjoined from providing advisory
and underwriting services to the Seligman Funds and other registered investment
companies. Seligman does not believe that the foregoing legal action or other
possible actions will have a material adverse impact on Seligman or its clients,
including the Seligman Funds and other investment companies managed by it;
however, there can be no assurance of this or that these matters and any related
publicity will not affect demand for shares of the Seligman Funds and such other
investment companies or have other adverse consequences.

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


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.

11. SUBSEQUENT EVENT

Effective Dec. 15, 2008, the Fund will pay custodian fees to JPMorgan Chase
Bank, NA.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ------------------------

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
RIVERSOURCE DISCIPLINED INTERNATIONAL EQUITY FUND:


We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of RiverSource Disciplined International Equity
Fund (the Fund) (one of the portfolios constituting the RiverSource
International Series, Inc) as of October 31, 2008, and the related statement of
operations for the year then ended, and the statements of changes in net assets
and the financial highlights for each of the two years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits. The financial
highlights of the Fund for the periods presented through October 31, 2006, were
audited by other auditors whose report dated December 20, 2006, expressed an
unqualified opinion on those financial highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of October 31, 2008, by correspondence with the custodian
and brokers, or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide a reasonable basis
for our opinion.

for the year then ended, and changes in its net assets and the financial

MANAGER COMMENTARY -------------------------------------------------------------



Below, Threadneedle European Equity Fund's portfolio manager Rob Jones of
Threadneedle International Limited (Threadneedle) discusses the Fund's results
and positioning for the fiscal year ended Oct. 31, 2008. Threadneedle, an
indirect wholly-owned subsidiary of Ameriprise Financial, Inc., acts as the
subadvisor to the Fund.

Dear Shareholders,

Threadneedle European Equity Fund (the Fund) Class A shares declined 42.70%
(excluding sales charge) for the 12 months ended Oct. 31, 2008. The Fund
outperformed its benchmark, the Morgan Stanley Capital International (MSCI)
Europe Index (MSCI Europe Index), which fell 47.71%. The Lipper European Funds
Index, representing the Fund's peer group, declined 49.06% for the same time
frame.

SIGNIFICANT PERFORMANCE FACTORS
As the Fund's fiscal year began, the investment markets were already quite
concerned about financial stocks, particularly companies with exposure to credit
vehicles. However, problems in the financial sector were not yet affecting
global economic activity and emerging market economies were still growing.
Investors pondered whether commodity prices would remain high and whether
emerging market economies could "decouple" from the rest of the world,
continuing to grow despite slower economic activity in developed regions. Thus,
the first part of the fiscal

6  THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT



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

year was characterized by financial sector weakness and robust gains in
companies with exposure to commodities or emerging markets.

Subsequently, the situation for many financial companies deteriorated
dramatically, lack of liquidity paralyzed the credit markets and there were
clear signs of economic deterioration, even in emerging economies. Equity
markets across the globe fell sharply and governments stepped in, rescuing
failing companies and attempting to calm the markets by adding liquidity to the
financial system.

Though the Fund's performance reflects the difficult environment, results
relative to the MSCI Europe Index benefited from the Fund's sector positioning
throughout the period. At the beginning of the fiscal year, the Fund was
underweight in financials relative to the MSCI Europe Index, with minimal
exposure to the banking sector. At the same time, we emphasized holdings of
commodity stocks, especially mining firms. The Fund also had notable holdings of
European companies with exposure to emerging markets. Examples included JERONIMO
MARTINS, a Portuguese food retailer focused on Poland, STANDARD CHARTERED, a
U.K. banking firm with a significant Asian business, and several Greek banks.

Over the course of the year, we increased the Fund's focus on defensive stocks,
building exposure to pharmaceutical, health care and consumer staples stocks.
Our rationale was that consumer staples companies such as NESTLE and BRITISH
AMERICAN TOBACCO and pharmaceutical firms such as

MANAGER COMMENTARY (continued) -------------------------------------------------


ROCHE HOLDING, ASTRAZENECA and NOVARTIS had relatively steady earnings streams,
were less dependent on economic activity and were trading at historically low
valuations. We saw these as compelling opportunities. Simultaneously, we reduced
holdings of industrial and technology companies, which we considered vulnerable
to the economic slowdown. We also maintained the Fund's underweight in
financials, believing there was still downside risk in the sector. The shift
toward more defensive positioning was beneficial.

To summarize how the Fund's positioning contributed to its outperformance of the
MSCI Europe Index, having a smaller financials positions than the MSCI Europe
Index added to relative performance, as did our reduction in the industrials
position. Having larger positions in pharmaceuticals, other health care stocks
and consumer staples stocks also added to relative performance.

Early in the period, the Fund had smaller weightings in telecommunications and
utilities than the MSCI Europe Index. Though we later added to those positions,
the initial underweights detracted. The Fund's emphasis on companies with
exposure to emerging markets was beneficial in the first half of the period, but
continuing to hold those stocks in the latter part of the year was
disadvantageous.

CHANGES TO THE FUND'S PORTFOLIO
As we became more concerned about the extent of the global economic slowdown
during the first calendar quarter of 2008, we reduced exposure to European
industrial stocks, particularly mid-cap companies that depended on the domestic
European economies. We sold several German stocks including truck manufacturer
MAN, sports car maker PORSCHE AUTOMOBIL HOLDING and tire and auto parts maker
CONTINENTAL. We also sold VALLOUREC, a French company that makes seamless pipes
for the oil industry, and ROLLS-ROYCE, the U.K. civil aviation engine company.

The portfolio had been underweight in pharmaceutical companies and overweight in
consumer defensive areas. As discussed above, we added to both sectors, moving
to an overweight in pharmaceuticals and increasing the overweight in defensive
consumer stocks. In addition to the pharmaceutical stocks noted above, we also
added health care stocks FRESENIUS MEDICAL CARE & CO., a renal care company, and
SYNTHES, a company that produces equipment used in reconstructive surgery for
trauma victims.

Through most of the year, we remained optimistic that emerging markets could
continue to grow faster than the developed nations, so we continued

- --------------------------------------------------------------------------------
8  THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT



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


to emphasize companies with exposure to the emerging markets. We bought
PRUDENTIAL which has a large Asian insurance business. Later in the period, as
we became more concerned that difficulties in the developed markets would hinder
emerging markets, we repositioned the Fund's commodity holdings, selling two
mining companies ANGLO AMERICAN and LONMIN, as well as SAIPEM, an Italian oil
services company. In their place, we bought larger, high dividend yield stocks
such as ROYAL DUTCH SHELL and BP. We consider these stocks more defensive and
believe their earnings streams are more secure. Toward the end of the period, we
also reduced our holdings of companies with significant business in the emerging
markets.

We added to the Fund's telecommunications holdings including purchases of
KONINKLIJKE (ROYAL) KPN, the Dutch telecommunications company, and FRANCE
TELECOM and increased the weighting in utilities with purchases of French
utility GDF SUEZ and U.K. electricity supplier CENTRICA. The Fund's turnover
rate for the fiscal year was 180%.

To summarize current positioning, the Fund has greater emphasis on defensive
stocks compared to the MSCI Europe Index, which includes overweights in health
care firms and consumer staples companies, for example food retailers. The Fund
has less emphasis on companies that depend on a strong economy, which means
smaller positions in industrial, technology and financial companies compared to
the MSCI Europe Index.

OUR FUTURE STRATEGY
We believe economic activity is likely to be weak for a while, but to some
extent, that is already reflected in stock prices. We have kept the portfolio
defensively positioned, but on the periphery we are finding some economically
sensitive stocks whose valuations seem to


  As we evaluate current opportunities, we are particularly focused on companies
  with solid balance sheets and high cash flow.

adequately reflect future challenges. As we evaluate current opportunities, we
are particularly focused on companies with solid balance sheets and high cash
flow. Our goal is to minimize risk by staying away from companies that we
believe could get into financial difficulty.

European authorities have begun to aggressively reduce interest rates and have
talked about increasing government spending to pump money into the economies.
Ultimately, we believe these steps will have a favorable impact. Thus, in the
short-term, we expect weaker earnings news, but we are optimistic that
government actions will have a positive long-term effect.

THE FUND'S LONG-TERM PERFORMANCE -----------------------------------------------

The chart on the facing page illustrates the total value of an assumed $10,000
investment in Threadneedle European Equity Fund Class A shares (from 7/1/00 to
10/31/08)* as compared to the performance of two widely cited performance
indices, the Morgan Stanley Capital International (MSCI) Europe Index and the
Lipper European Funds Index. In comparing the Fund's Class A shares to these
indices, you should take into account the fact that the Fund's performance
reflects the maximum sales charge of 5.75%, while such charges are not reflected
in the performance of the indices. Returns for the Fund include the reinvestment
of any distribution paid during each period.

The performance information shown represents past performance and is not a
guarantee of future results. The table below and the chart on the facing page do
not reflect the deduction of taxes that a shareholder would pay on fund
distributions or the redemption of fund shares. The investment return and
principal value of your investment will fluctuate so that your shares, when
redeemed, may be worth more or less than their original cost. Current
performance may be lower or higher than the performance information shown. You
may obtain performance information current to the most recent month-end by
contacting your financial institution or visiting riversource.com/funds. Also

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

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1) fees;
and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the expenses of the funds in which it invests (also
referred to as "acquired funds"), including affiliated and non-affiliated pooled
investment vehicles (including mutual funds and exchange traded funds). The
Fund's indirect expense from investing in the acquired funds is based on the
Fund's pro rata portion of the cumulative expenses charged by the acquired funds
using the 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 Oct. 31, 2008.

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.

NOTES TO FINANCIAL STATEMENTS --------------------------------------------------


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Threadneedle European Equity Fund (the Fund) (formerly RiverSource European
Equity 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 Oct. 31, 2008, 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
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

- --------------------------------------------------------------------------------
                     THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT  27



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


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 and therefore the closing prices for securities
in such markets or on such exchanges may not fully reflect events that occur
after such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial, 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 New
York Stock Exchange.

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

- --------------------------------------------------------------------------------
28  THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT



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


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 New York Stock Exchange. The Fund will realize a gain or loss when
the option transaction expires or closes. When an option is exercised, the
proceeds on sales for a written call option, the purchase cost for a written put
option or the cost of a security for a purchased put or call option is adjusted
by the amount of premium received or paid. At Oct. 31, 2008, and for the year
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 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
Oct. 31, 2008, 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

- --------------------------------------------------------------------------------
                     THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT  29



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


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 Oct. 31, 2008, 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.

Financial Accounting Standards Board (FASB) Interpretation 48 (FIN 48),
"Accounting for Uncertainty in Income Taxes," clarifies the accounting for
uncertainty in income taxes recognized in accordance with FASB Statement 109,
"Accounting for Income Taxes." FIN 48 provides guidance for how uncertain tax
positions should be recognized, measured, presented and disclosed in the
financial statements. 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.

On the Statement of Assets and Liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been decreased by $57,205
and accumulated net realized loss has been decreased by $57,205.

The tax character of distributions paid for the years indicated is as follows:

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


RECENT ACCOUNTING PRONOUNCEMENTS
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. 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, and (c) how
derivative instruments and related hedged items affect a fund's financial
position, financial performance, and cash flows. SFAS 161 is effective for
financial statements issued for periods beginning after Nov. 15, 2008. As of
Oct. 31, 2008, 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 Sept. 20, 2006, the FASB released Statement of Financial Accounting Standards
No. 157 "Fair Value Measurements" (SFAS 157). SFAS 157 establishes an
authoritative definition of fair value, sets out a 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. The application of SFAS 157
will be effective for the Fund's fiscal year beginning Nov. 1, 2008. The
adoption of SFAS 157 is not anticipated to have a material impact on the Fund's
financial statements; however, additional disclosures will be required 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.

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 $19,559 for the year ended
Oct. 31, 2008. The management fee for the year ended Oct. 31, 2008 was 0.82% 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
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 year ended Oct. 31, 2008 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 year ended Oct. 31,
2008, other expenses paid to this company were $574.

COMPENSATION OF BOARD MEMBERS
Compensation of Board members includes, for a former Board Chair, compensation
as well as retirement benefits. Certain other aspects of a former

- --------------------------------------------------------------------------------
                     THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT  33



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


Board Chair's compensation, including health benefits and payment of certain
other expenses, are included under other expenses.

Under a Deferred Compensation Plan (the Plan), non-interested board members may
defer receipt of their compensation. Deferred amounts are treated as though
equivalent dollar amounts had been invested in shares of the Fund or other
RiverSource funds. The Fund's liability for these amounts is adjusted for market
value changes and remains in the Fund until distributed in accordance with the
Plan.

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 on the Statement of Operations.

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

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Distributors, Inc. (the Distributor)
for distribution and shareholder services. Under a Plan and Agreement of
Distribution pursuant to Rule 12b-1, the Fund pays a fee at an annual rate of up
to 0.25% of the Fund's average daily net assets attributable to Class A 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 $226,000 and $11,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of Oct. 31, 2008, 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 received by the Distributor for distributing Fund shares were
$111,829 for Class A, $12,495 for Class B and $504 for Class C for the year
ended Oct. 31, 2008.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the year ended Oct. 31, 2008, 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 B.............................................  2.32
Class C.............................................  2.33

The waived/reimbursed fees and expenses for the transfer agency fees at the
class level were as follows:

Class A...........................................  $  492
Class B...........................................   1,649
Class C...........................................      85
</Table>


The waived/reimbursed fees and expenses for plan administration services fee at

Class R4............................................  $72
</Table>


Under an agreement which was effective until Oct. 31, 2008, the Investment
Manager and its affiliates contractually agreed to waive certain fees and
expenses such that net expenses (excluding fees and expenses of acquired
funds*), before giving effect to any performance incentive adjustment, would not
exceed the following percentage of the Fund's average daily net assets:

<Table>

Class I.............................................  1.15
Class R4............................................  1.39
</Table>


Effective Nov. 1, 2008, 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 Fund's average daily net assets:

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.

EARNINGS AND BANK FEE CREDITS
During the year ended Oct. 31, 2008, the Fund's custodian and transfer agency
fees were reduced by $2,640 as a result of earnings bank fee credits from
overnight cash balances. The Fund pays custodian fees 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 $212,659,427 and $232,428,742, respectively, for the
year ended Oct. 31, 2008. Realized gains and losses are determined on an
identified cost basis.

Income from securities lending amounted to $10,142 for the year ended Oct. 31,
2008. Expenses paid to the Investment Manager as securities lending agent were
$1,086 for the year ended Oct. 31, 2008, which are included in other expenses on
the Statement of Operations. The risks to the Fund of securities lending are
that the borrower may not provide additional collateral when required or return
the securities when due. At Oct. 31, 2008, the Fund had no securities out on
loan.

5. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund,
a money market fund established for the exclusive use of the RiverSource funds
and other institutional clients of RiverSource Investments. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash Fund aggregated $85,312,789 and $87,734,600, respectively, for the year
ended Oct. 31, 2008. The income distributions received with respect to the
Fund's investment in RiverSource Short-Term Cash Fund can be found on the
Statement of Operations and the Fund's invested balance in RiverSource Short-
Term Cash Fund at Oct. 31, 2008, can be found in the Portfolio of Investments.

6. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or emergency
purposes. The credit facility became effective on Oct. 16, 2008, replacing a
prior credit facility. The credit facility agreement, which is a collective
agreement between the Fund and certain other RiverSource funds,

- --------------------------------------------------------------------------------
                     THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT  37



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



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 year ended Oct. 31, 2008.

Under the prior credit facility which was effective until Oct. 15, 2008, the
Fund had entered into a revolving credit facility with a syndicate of banks
headed by JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund was permitted to
borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility agreement, which was a
collective agreement between the Fund and certain other RiverSource funds,
severally and not jointly, permitted collective borrowings up to $500 million.
Interest was charged to each Fund based on its borrowings at a rate equal to the
federal funds rate plus 0.30%. Each borrowing under the credit facility matured
no later than 60 days after the date of borrowing. The Fund also paid a
commitment fee equal to its pro rata share of the amount of the credit facility
at a rate of 0.06% per annum.

7. 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.

8. 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.

9. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc., was filed in the
United States District Court for the District of Arizona. The plaintiffs allege
that they are investors in several American Express Company mutual funds and
they purport to bring the action derivatively on behalf of those funds under the
Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid
to the defendants by the funds for investment advisory and administrative
services are excessive. The plaintiffs seek remedies including restitution and
rescission of investment advisory and distribution agreements. The plaintiffs
voluntarily agreed to transfer this case to the United States District Court for
the District of Minnesota. In response to defendants' motion to dismiss the
complaint, the Court dismissed one of plaintiffs' four claims and granted
plaintiffs limited discovery. Defendants moved for summary judgment in April
2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The
plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals on
August 8, 2007.

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 2005, the New
York staff of the SEC indicated that it was considering recommending to the
Commissioners of the SEC the instituting of a formal action against Seligman and
the distributor of the Seligman Funds, 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.

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc., Seligman Data Corp. (transfer
agent for the Seligman Funds) and Brian T. Zino (collectively, the Seligman
Parties), alleging, in substance, that, in addition to the four arrangements
noted above, the Seligman Parties permitted other persons to engage in frequent
trading and, as a result, the prospectus disclosure used by the registered
investment companies 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. The NYAG is seeking damages of at least
$80 million and restitution, disgorgement, penalties and costs and injunctive
relief. The Seligman Parties answered the complaint in December 2006 and believe
that the claims are without merit. Any resolution of these matters may include

would be paid by Seligman and not by the Seligman Funds. If the NYAG obtains
injunctive relief, Seligman and its affiliates could, in

the absence of the SEC in its discretion granting exemptive relief, be enjoined
from providing advisory and underwriting services to the Seligman Funds and
other registered investment companies. Seligman does not believe that the
foregoing legal action or other possible actions will have a material adverse
impact on Seligman or its clients, including the Seligman Funds and other
investment companies managed by it; however, there can be no assurance of this
or that these matters and any related publicity will not affect demand for
shares of the Seligman Funds and such other investment companies or have other
adverse consequences.

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.

10. SUBSEQUENT EVENT

Effective Dec. 15, 2008, the Fund will pay custodian fees to JPMorgan Chase
Bank, N.A. and, in addition, JPMorgan Chase Bank, N.A. will serve as the
securities lending agent for the Fund.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ------------------------

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
THREADNEEDLE EUROPEAN EQUITY FUND:


We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Threadneedle European Equity Fund (the Fund),
formerly the RiverSource European Equity Fund, (one of the portfolios
constituting the RiverSource International Series, Inc.) as of October 31, 2008,
and the related statement of operations for the year then ended, and the
statements of changes in net assets and the financial highlights for each of the
two years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits. The financial highlights of the Fund for the periods
presented through October 31, 2006, were audited by other auditors whose report
dated December 20, 2006, expressed an unqualified opinion on those financial
highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2008, by correspondence with the custodian
and brokers, or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide a reasonable basis
for our opinion.


- --------------------------------------------------------------------------------
42  THREADNEEDLE EUROPEAN EQUITY FUND -- 2008 ANNUAL REPORT



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


In our opinion, the financial statements and financial highlights audited by us
as referred to above present fairly, in all material respects, the financial
position of Threadneedle European Equity Fund of the RiverSource International
Series, Inc. at October 31, 2008, the results of its operations for the year
then ended, and changes in its net assets and the financial highlights for each
of the two years in the period then ended, in conformity with U.S. generally
accepted accounting principles.

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

The 5.75% sales charge applicable to Class A shares of the Fund is not reflected
in the 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.

6  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT



MANAGER COMMENTARY -------------------------------------------------------------

Threadneedle International Opportunity Fund portfolio managers Alex Lyle and
Esther Perkins of Threadneedle International Limited (Threadneedle) discuss the
Fund's results and positioning for the fiscal period ended Oct. 31, 2008.
Threadneedle, an indirect wholly-owned subsidiary of Ameriprise Financial, Inc.,
acts as the subadvisor to the Fund.

Dear Shareholders,

Threadneedle International Opportunity Fund (the Fund) Class A shares declined
44.46% (excluding sales charge) for the fiscal year ended Oct. 31, 2008. The
Fund outperformed its benchmark index, the Morgan Stanley Capital International
(MSCI) EAFE Index (MSCI EAFE Index), which fell 46.34% for the period. The Fund
also outperformed the Lipper International Large-Cap Core Funds Index,
representing the Fund's peer group, which declined 46.67% for the same time
frame.

SIGNIFICANT PERFORMANCE FACTORS
Global investment markets have performed quite poorly due to the liquidity
shortage in the credit markets and deteriorating expectations for global
economic growth. Many global economies are already in recession and we
anticipate others will follow. The outlook for corporate earnings has also
worsened, and we expect earnings in most regions to decline. Hence, the equity
markets have faced a difficult backdrop.

            THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT  7



MANAGER COMMENTARY (continued) -------------------------------------------------

Though the Fund's absolute returns reflect the challenging environment, the Fund
has withstood the equity decline better than the MSCI EAFE Index and its peers.
The primary reason for the better relative performance was an emphasis on more
defensive, less economically dependant companies. These include consumer staples

telecommunications sector held up well in the difficult market and VODAFONE and
KONINKLIJKE KPN were strong performers for the Fund.

Having smaller positions in underperforming sectors like industrials and
financials than the MSCI EAFE Index was another positive for the Fund. In the
banking segment, having limited exposure to HBOS and RBS in the U.K. and UBS in
Switzerland was advantageous.

In the early part of the fiscal year, the Fund's emphasis on energy and mining
stocks was effective. These groups performed well when the economic outlook was
still somewhat optimistic, commodity supplies were constrained and commodity
prices remained high. Examples of contributors in this area included Brazilian
oil producer PETROLEO BRASILEIRO and U.K. oil companies BG GROUP and TULLOW OIL.
Each had promising oil discoveries during the period. Toward the end of the year
as the economic outlook soured and commodity prices fell, the Fund gave back
some of its earlier gains in these sectors. Swiss mining company XSTRATA was a
notably poor performer late in the period. We subsequently reduced the Fund's
energy and mining positions.

The portfolio's holdings of Russian and Asian companies also detracted from
performance. Russian companies underperformed due to high debt levels and
concerns about lack of investor protection under Russian law. We sold MECHEL, a
Russian coal and steel producer and ROSNEFT, a Russian oil company. Portfolio
holdings in China and Hong Kong performed quite well last year, but CHINA
MERCHANT BANK and CHINA OVERSEAS


  We continue to emphasize defensive sectors that have limited dependence on the
  economic cycle.

MANAGER COMMENTARY (continued) -------------------------------------------------


LAND suffered from some profit-taking early in this fiscal period and economic
concerns in the second half of the year.

CHANGES TO THE FUND'S PORTFOLIO
We increased the Fund's holdings of consumer staples stocks, adding to NESTLE
and to PERNOD RICARD, a beverage company that made an acquisition we believe has
great potential. In Japan we added two new holdings in the beverage sector,
KIRIN HOLDINGS and ASAHI BREWERIES.

In the health care sector, new positions included the Swiss pharmaceutical firm
NOVARTIS, the French pharmaceutical company SANOFI-AVENTIS and FRESENIUS MEDICAL
CARE. We believe the health care sector has good long-term potential.

We also built up the portfolio's telecommunications position with new holdings
in FRANCE TELECOM and in Japan, NTT DATA and NTT DOCOMO.

We reduced exposure to industrials, selling U.K. civil aviation engine company
ROLLS-ROYCE and three German stocks, truck company MAN, sports car maker PORSCHE
and auto parts company CONTINENTAL. We reduced the Fund's oil company holdings
near the end of the period, selling PETROLEO BRASILEIRO and ROSNEFT and reducing
the Fund's holdings of TULLOW OIL. We also cut back on mining stocks, selling
XSTRATA, ANGLO AMERICAN and LONMIN.

We reduced the Fund's exposure to emerging market stocks, given investors'
continued risk aversion. We sold Brazilian builder CYRELA, South African media
stock NASPERS and IMPALA PLATINUM, also in South Africa.

OUR FUTURE STRATEGY
Looking forward, we anticipate that economic and market environments will remain
difficult, so we have focused on companies with healthy balance sheets that we
believe are strong players within their specific sectors. We continue to
emphasize defensive sectors that have limited dependence on the economic cycle.
Thus, the portfolio has larger positions in health care, consumer staples and
telecommunications than the MSCI EAFE Index. The portfolio's holdings of
industrials and

- --------------------------------------------------------------------------------
10  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT



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

consumer discretionary stocks are smaller than the MSCI EAFE Index, as is its
position in the banking industry group.

In our view, share prices already reflect a lot of bad news, so we do see some
upside potential. We expect inflation to come down materially, giving central
banks room to reduce interest rates, which may spur a rally within this
environment. However, we don't think equities are ready to break into a new bull
market. Before that could occur, we believe we would need to be further along in
the recessionary phase of the economic cycle. Still, we recognize that poorly
performing areas are expected to recover at some point and, therefore, we are
looking to add very selectively in poor performing sectors, including retailers,
auto stocks and banks.

Geographically, we're most enthusiastic about opportunities in the U.K.,
primarily due to attractive valuations. We also see potential in Asia where we
still expect superior growth rates compared to other regions.

THE FUND'S LONG-TERM PERFORMANCE -----------------------------------------------

The chart on the facing page illustrates the total value of an assumed $10,000
investment in Threadneedle International Opportunity Fund Class A shares (from
11/1/98 to 10/31/08) as compared to the performance of two widely cited
performance indices, the Morgan Stanley Capital International (MSCI) EAFE Index
and the Lipper International Large-Cap Core Funds Index. In comparing the Fund's
Class A shares to these indices, you should take into account the fact that the
Fund's performance reflects the maximum sales charge of 5.75%, while such
charges are not reflected in the performance of the indices. Returns for the
Fund include the reinvestment of any distribution paid during each period.

The performance information shown represents past performance and is not a
guarantee of future results. The table below and the chart on the facing page do
not reflect the deduction of taxes that a shareholder would pay on fund
distributions or the redemption of fund shares. The investment return and
principal value of your investment will fluctuate so that your shares, when
redeemed, may be worth more or less than their original cost. Current
performance may be lower or higher than the performance information shown. You
may obtain performance information current to the most recent month-end by
contacting your financial institution or visiting riversource.com/funds. Also

           THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT  13



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

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1) fees;
and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the expenses of the funds in which it invests (also
referred to as "acquired funds"), including affiliated and non-affiliated pooled
investment vehicles (including mutual funds and exchange traded funds). The
Fund's indirect expense from investing in the acquired funds is based on the
Fund's pro rata portion of the cumulative expenses charged by the acquired funds
using the 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 Oct. 31, 2008.

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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Threadneedle International Opportunity Fund (the Fund) (formerly RiverSource
International Opportunity 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 Oct. 31, 2008, 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,
liabilities and contingent assets and liabilities) that could differ from actual
results.


- --------------------------------------------------------------------------------
34  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT



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


VALUATION OF SECURITIES
All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
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 and therefore the closing prices for securities
in such markets or on such exchanges may not fully reflect events that occur
after such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial, 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 New
York Stock Exchange.

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

- --------------------------------------------------------------------------------
           THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT  35



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

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 form independent brokers as of the
close of the New York Stock Exchange. The Fund will realize a gain or loss when
the option transaction expires or closes. When an option is exercised, the
proceeds on sales for a written call option, the purchase cost for a written put
option or the cost of a security for a purchased put or call option is adjusted
by the amount of premium received or paid. At Oct. 31, 2008, and for the year
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 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

- --------------------------------------------------------------------------------
36  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT



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



recognizes a realized gain or loss when the contract is closed or expires. At
Oct. 31, 2008, 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 Oct. 31, 2008, 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.

Financial Accounting Standards Board (FASB) Interpretation 48 (FIN 48),
"Accounting for Uncertainty in Income Taxes," clarifies the accounting for
uncertainty in income taxes recognized in accordance with FASB Statement 109,

- --------------------------------------------------------------------------------
           THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT  37



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


"Accounting for Income Taxes." FIN 48 provides guidance for how uncertain tax
positions should be recognized, measured, presented and disclosed in the
financial statements. 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.

On the Statement of Assets and Liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been decreased by $39,727
and accumulated net realized loss has been decreased by $39,727.

The tax character of distributions paid for the years indicated is as follows:

RECENT ACCOUNTING PRONOUNCEMENTS
In March 2008, the FASB issued Statement on 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. 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, and (c) how
derivative instruments and related hedged items affect a fund's financial
position, financial performance, and cash flows. SFAS 161 is effective for
financial statements issued for periods beginning after Nov. 15, 2008. As of
Oct. 31, 2008, 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.


- --------------------------------------------------------------------------------
           THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT  39



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

On Sept. 20, 2006, the FASB released Statement of Financial Accounting Standards
No. 157 "Fair Value Measurements" (SFAS 157). SFAS 157 establishes an
authoritative definition of fair value, sets out a 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. The application of SFAS 157
will be effective for the Fund's fiscal year beginning Nov. 1, 2008. The
adoption of SFAS 157 is not anticipated to have a material impact on the Fund's
financial statements; however, additional disclosures will be required 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.

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
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 $119,014 for the year ended
Oct. 31, 2008. The management fee for the year ended Oct. 31, 2008 was 0.80% of
the Fund's average daily net assets, including the adjustment under the terms of
the performance incentive arrangement.


- --------------------------------------------------------------------------------
40  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT



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


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 year ended Oct. 31, 2008 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 year ended Oct. 31,
2008, other expenses paid to this company were $3,057.

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

Under a Deferred Compensation Plan (the Plan), non-interested board members may
defer receipt of their compensation. Deferred amounts are treated as though
equivalent dollar amounts had been invested in shares of the Fund or other
RiverSource funds. The Fund's liability for these amounts is adjusted for market
value changes and remains in the Fund until distributed in accordance with the
Plan.

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.


- --------------------------------------------------------------------------------
           THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT  41



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

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

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

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Distributors, Inc. (the Distributor)
for distribution and shareholder services. Under a Plan and Agreement of
Distribution pursuant to Rule 12b-1, the Fund pays a fee at an annual rate of up
to 0.25% of the Fund's average daily net assets attributable to Class A and
Class R3 shares, a fee at an annual rate of up to 0.50% of the Fund's average
daily net assets attributable to Class R2 shares and a fee at an annual rate of
up to 1.00% of the Fund's average daily net assets attributable to Class B and
Class C shares. For Class B and Class C shares, 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 $968,000 and $26,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of Oct. 31, 2008, 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
$289,246 for Class A, $30,296 for Class B and $308 for Class C for the year
ended Oct. 31, 2008.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the year ended Oct. 31, 2008, 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............................................  1.52%
Class R3............................................  1.27
Class R4............................................  1.01
</Table>




- --------------------------------------------------------------------------------
42  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT



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


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

<Table>
                                                  
Class R2...........................................  $ 12
Class R3...........................................    12
Class R4...........................................   730
</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 Fund's 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.

EARNINGS AND BANK FEE CREDITS
During the year ended Oct. 31, 2008, the Fund's custodian and transfer agency
fees were reduced by $14,466 as a result of earnings and bank fee credits from
overnight cash balances. The Fund pays custodian fees 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 $450,532,975 and $515,292,634 respectively, for the year
ended Oct. 31, 2008. Realized gains and losses are determined on an identified
cost basis.

Income from securities lending amounted to $359,229 for the year ended Oct. 31,
2008. Expenses paid to the Investment Manager as securities lending agent were
$3,007 for the year ended Oct. 31, 2008, which are included in other expenses on
the Statement of Operations. The risks to the Fund of securities lending are
that the borrower may not provide additional collateral when required or return
the securities when due. At Oct. 31, 2008, the Fund had no securities out on
loan.

*   For the period from Dec. 11, 2006 (inception date) to Oct. 31, 2007.

5. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund,
a money market fund established for the exclusive use of the RiverSource funds
and other institutional clients of RiverSource Investments. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash Fund aggregated $270,934,515 and $276,499,409, respectively, for the year
ended Oct. 31, 2008. The income distributions received with respect to the
Fund's investment in RiverSource Short-Term Cash Fund can be found on the
Statement of Operations and the Fund's invested balance in RiverSource Short-
Term Cash Fund at Oct. 31, 2008, can be found in the Portfolio of Investments.

6. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for

- --------------------------------------------------------------------------------
44  THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT



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



the temporary funding of shareholder redemptions or for other temporary or
emergency purposes. The credit facility became effective on Oct. 16, 2008,
replacing a prior credit facility. 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 year ended Oct. 31, 2008.

Under the prior credit facility which was effective until Oct. 15, 2008, the
Fund had entered into a revolving credit facility with a syndicate of banks
headed by JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund was permitted to
borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility agreement, which was a
collective agreement between the Fund and certain other RiverSource funds,
severally and not jointly, permitted collective borrowings up to $500 million.
Interest was charged to each Fund based on its borrowings at a rate equal to the
federal funds rate plus 0.30%. Each borrowing under the credit facility matured
no later than 60 days after the date of borrowing. The Fund also paid a
commitment fee equal to its pro rata share of the amount of the credit facility
at a rate of 0.06% per annum.

7. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund has 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.

8. 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.

9. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc., was filed in the
United States District Court for the District of Arizona. The plaintiffs allege
that they are investors in several American Express Company mutual funds and
they purport to bring the action derivatively on behalf of those funds under the
Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid
to the defendants by the funds for investment advisory and administrative
services are excessive. The plaintiffs seek remedies including restitution and
rescission of investment advisory and distribution agreements. The plaintiffs
voluntarily agreed to transfer this case to the United States District Court for
the District of Minnesota. In response to defendants' motion to dismiss the
complaint, the Court dismissed one of plaintiffs' four claims and granted
plaintiffs limited discovery. Defendants moved for summary judgment in April
2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The
plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals on
August 8, 2007.

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 2005, the New
York staff of the SEC indicated that it was considering recommending to the
Commissioners of the SEC the instituting of a formal action against Seligman and
the distributor of the Seligman Funds, 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.

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc., Seligman Data Corp. (transfer
agent for the Seligman Funds) and Brian T. Zino (collectively, the Seligman
Parties), alleging, in substance, that, in addition to the four arrangements
noted above, the Seligman Parties permitted other persons to engage in frequent
trading and, as a result, the prospectus disclosure used by the registered
investment companies 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. The NYAG is seeking damages of at least
$80 million and restitution, disgorgement, penalties and costs and injunctive
relief. The Seligman Parties answered the complaint in December 2006 and believe
that the claims are without merit. Any resolution of these matters may include
the relief noted above or other sanctions or changes in procedures. Any damages
would be paid by Seligman and not by the Seligman Funds. If the NYAG obtains
injunctive relief, Seligman and its affiliates could, in the absence of the SEC
in its discretion granting exemptive relief, be enjoined

           THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND -- 2008 ANNUAL REPORT  47



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


from providing advisory and underwriting services to the Seligman Funds and
other registered investment companies. Seligman does not believe that the
foregoing legal action or other possible actions will have a material adverse
impact on Seligman or its clients, including the Seligman Funds and other
investment companies managed by it; however, there can be no assurance of this
or that these matters and any related publicity will not affect demand for
shares of the Seligman Funds and such other investment companies or have other
adverse consequences.

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.

10. SUBSEQUENT EVENT

Effective Dec. 15, 2008, the Fund will pay custodian fees to JPMorgan Chase
Bank, N.A. and, in addition, JPMorgan Chase Bank, N.A. will serve as the
securities lending agent for the Fund.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ------------------------

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
THREADNEEDLE INTERNATIONAL OPPORTUNITY FUND:


We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Threadneedle International Opportunity Fund
(the Fund), formerly the RiverSource International Opportunity Fund, (one of the
portfolios constituting the RiverSource International Series, Inc.) as of
October 31, 2008, and the related statement of operations for the year then
ended, and the statements of changes in net assets and the financial highlights
for each of the two years in the period then ended. These financial statements
and financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits. The financial highlights of the Fund
for the periods presented through October 31, 2006, were audited by other
auditors whose report dated December 20, 2006, expressed an unqualified opinion
on those financial highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audits to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not engaged to perform an audit of the Fund's internal control over
financial reporting. Our audits included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Fund's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of October 31, 2008, by correspondence with the custodian
and brokers, or by other appropriate auditing procedures where replies from
brokers were not received. We believe that our audits provide a reasonable basis
for our opinion.
