Bond ratings apply to underlying holdings of the Fund and not the Fund itself.
Whenever possible, the Standard and Poor's rating is used to determine the
credit quality of a security. Standard and Poor's rates the creditworthiness of
corporate bonds, with 15 categories, ranging from AAA (highest) to D (lowest).
Ratings from AA to CCC may be modified by the addition of a plus (+) or minus
(-) sign to show relative standing within the major rating categories. If
Standard and Poor's doesn't rate a security, then Moody's rating is used.
RiverSource Investments, LLC, the Fund's investment manager, rates a security
using an internal rating system when Moody's doesn't provide a rating.

 6 RIVERSOURCE ABSOLUTE RETURN CURRENCY AND INCOME FUND -- 2007 SEMIANNUAL
REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Nic Pifer, portfolio manager for RiverSource Absolute Return Currency and
Income Fund, discusses the Fund's results and positioning for the six-month
period ended April 30, 2007.

At April 30, 2007, approximately 96% of the Fund's shares were owned in the
aggregate by affiliated funds-of-funds managed by RiverSource Investments, LLC
(RiverSource). As a result of asset allocation decisions by RiverSource, it is
possible that RiverSource Absolute Return Currency and Income Fund may
experience relatively large purchases or redemptions from affiliated
funds-of-funds (see page 28, Class I capital share transactions for related
activity during the most recent fiscal period). RiverSource seeks to minimize
the impact of these transactions by structuring them over a reasonable period of
time. RiverSource Absolute Return Currency and Income Fund may experience
increased expenses as it buys and sells securities as a result of purchases or
redemptions by affiliated funds-of-funds. For more information on the Fund's
expenses, see the discussions beginning on pages 10 and 25.

Q: How did RiverSource Absolute Return Currency and Income Fund perform for the
   six months ended April 30, 2007?

A: RiverSource Absolute Return Currency and Income Fund's Class A shares
   increased 5.88% (excluding sales charge) for the six months ended April 30,
   2007. The Fund outperformed its benchmark, the Citigroup 3-Month U.S.
   Treasury Bill Index (Citigroup Index), which increased 2.50% during the same
   period.

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

A: We use a two-part investment process. The first part includes investments in
   high quality, short-term fixed income securities with minimal interest rate
   risk with a goal to generate positive total return. These short-term
   investments are also designated, as necessary, to cover obligations invested
   in through the second component of our strategy, which is based on a
   proprietary quantitative model. Our model uses various fundamental and
   technical factors, including current and historical data, to rank the
   anticipated value of nine different currencies from developed countries
   relative to the U.S. dollar. Based on that ranking, we enter into long
   forward currency contracts for the three most attractive currencies compared
   to the U.S. dollar and enter into short forward currency contracts for the
   three least attractive currencies compared to the U.S. dollar. The Fund
   experiences profits or losses to the extent the value of the currency
   appreciates or depreciates relative to the U.S. dollar.

         RIVERSOURCE ABSOLUTE RETURN CURRENCY AND INCOME FUND -- 2007 SEMIANNUAL

QUESTIONS & ANSWERS

   During the period, we were able to generate positive total return from our
   investment in short-term fixed income securities, and we were able to add
   additional value through the use of our proprietary quantitative model. For
   the six months ended April 30, 2007, the Fund's positioning in the New
   Zealand dollar, Norwegian krone, British pound, Japanese yen and Australian
   dollar benefited the Fund's results. Positioning in the Swedish krona, euro,
   Swiss franc and Canadian dollar detracted from the Fund's performance.

   DURING THE PERIOD, WE WERE ABLE TO GENERATE POSITIVE TOTAL RETURN FROM OUR
   INVESTMENT IN SHORT-TERM FIXED INCOME SECURITIES, AND WE WERE ABLE TO ADD
   ADDITIONAL VALUE THROUGH THE USE OF OUR PROPRIETARY QUANTITATIVE MODEL.


Q: How would you describe your current investment strategy?

A: We run our quantitative model weekly and reset currency positions as needed,
   applying the output of this model on a systematic basis. We generally seek
   neutral exposure to the U.S. dollar, which is the base currency. In our view,
   remaining neutral to the U.S. dollar helps control overall volatility of the
   investment strategy. We also use an externally developed but fully integrated
   risk management system to help us monitor and manage market risk.

Q: What is the Fund's tactical view and strategy for the months ahead?

A: We intend to stay disciplined to our systematic investment strategy. Through
   the use of our proprietary quantitative model, which determines the Fund's
   positions in forward foreign currency contracts relative to the U.S. dollar,
   we will continue to seek an absolute return that is unrelated to general
   movements in the U.S. dollar and other types of financial assets. Overall, we
   will continue to seek to generate positive total returns from the income
   produced by the Fund's investments in short-term debt obligations, plus or
   minus the gain or loss resulting from the fluctuations in the values of
   various foreign currencies relative to the U.S. dollar.

 8 RIVERSOURCE ABSOLUTE RETURN CURRENCY AND INCOME FUND -- 2007 SEMIANNUAL
REPORT

QUESTIONS & ANSWERS

   It is important to remember that the Fund does not actually take ownership of
   foreign currencies or sell actual foreign currencies. Rather, through forward
   currency contracts, the Fund gains economic exposure comparable to the
   exposure that it would have if it had bought or sold the currencies directly.
   Because the establishment of the Fund's forward foreign currency contracts
   requires little cash outlay, the Fund's assets will consist primarily of
   short-term U.S. dollar-denominated corporate debt securities rated investment
   grade, or, if unrated, determined to be of comparable quality.

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

FUND EXPENSES EXAMPLE

(UNAUDITED)

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

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

</Table>

(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended April 30, 2007: +5.88%
     for Class A, +5.39% for Class B, +5.39% for Class C, +6.02% for Class I and
     5.83% for Class R4.
(c)  In September 2006, the Board approved renaming Class Y as Class R4,
     terminating the shareholder servicing agreement, revising the fee structure
     under the transfer agent agreement from an account-based fee to an
     asset-based fee, and adopting a plan administration services agreement.
     These changes were effective Dec. 11, 2006. In addition, the investment
     manager and its affiliates have contractually agreed to waive certain fees
     and to absorb certain expenses until Oct. 31, 2007, unless sooner
     terminated at the discretion of the Fund's Board, such that net expenses
     (excluding fees and expenses of acquired funds), will not exceed 1.31% for
     Class R4. Any amounts waived will not be reimbursed by the Fund. If these
     changes had been in place for the six-month period ended April 30, 2007,
     the actual expenses paid for Class R4 would have been $6.69 and the
     hypothetical expenses paid for Class R4 would have been $6.56.
(d)  The actual values and expenses paid are not presented because Class W does
     not have a full six months of history. The inception date of Class W is
     Dec. 1, 2006.

than class specific expenses) and realized and unrealized gains or losses on
investments are allocated to each class of shares based upon its relative net
assets.

The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds generally contemplate the use of fair valuation in the
event that price quotations or valuations are not readily available, price
quotations or valuations from other sources are not reflective of market value
and thus deemed unreliable, or a significant event has occurred in relation to a
security or class of securities (such as foreign equities) that is not reflected
in price quotations or valuations from other sources. A fair value price is a
good faith estimate of the value of a security at a given point in time. Many
securities markets and exchanges outside the U.S. close prior to the close of
the New York Stock Exchange and therefore the closing prices for securities in
such markets or on such exchanges may not fully reflect events that occur after
such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, including utilizing a third party pricing service to determine these
fair values. These procedures take into account multiple factors, including
movements in the U.S. securities markets, to determine a good faith estimate
that reasonably reflects the current market conditions as of the close of the
New York Stock Exchange. 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.

SECURITIES PURCHASED ON A FORWARD-COMMITMENT BASIS

Delivery and payment for securities that have been purchased by the Fund on a
forward-commitment basis, including when-issued securities and other forward-
commitments, can take place one month or more after the transaction date. During
this period, such securities are subject to market fluctuations, and they may
affect the Fund's net assets the same as owned securities. The Fund designates
cash or liquid securities at least equal to the amount of its
forward-commitments. At April 30, 2007, the Fund has entered into outstanding
when-issued securities of $1,000,000.

The Fund also enters into transactions to sell purchase commitments to third
parties at current market values and concurrently acquires other purchase
commitments for similar securities at later dates. As an inducement for the Fund
to "roll over" its purchase commitments, the Fund receives negotiated amounts in
the form of reductions of the purchase price of the commitment.

OPTION TRANSACTIONS

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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

FUTURES TRANSACTIONS

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

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

 22 RIVERSOURCE ABSOLUTE RETURN CURRENCY AND INCOME FUND -- 2007 SEMIANNUAL
REPORT


Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the statement of operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes.

The Fund may enter into forward foreign currency exchange contracts to produce
incremental earnings, for operational purposes, or to protect against adverse
exchange rate fluctuation. The net U.S. dollar value of foreign currency
underlying all contractual commitments held by the Fund and the resulting
unrealized appreciation or depreciation are determined using foreign currency
exchange rates from an independent pricing service. The Fund is subject to the
credit risk that the other party will not complete its contract obligations.

PAYMENT FROM AFFILIATE

During the six months ended April 30, 2007, Ameriprise Financial voluntarily
reimbursed the Fund $44,795 for a loss on a trading error.

GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

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

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

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value, and requires additional disclosures
about fair-value measurements. The application of SFAS 157 is required for
fiscal years beginning after Nov. 15, 2007 and interim periods within those
fiscal years. The impact of SFAS 157 on the Fund's financial statements is being
evaluated.

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

DIVIDENDS TO SHAREHOLDERS

Dividends from net investment income, declared daily and payable monthly, when
available, are reinvested in additional shares of the Fund at net asset value or
payable in cash. Capital gains, when available, are distributed along with the
last income dividend of the calendar year.

OTHER

Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date or upon receipt of
ex-dividend notification in the case of certain foreign securities. Interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments, LLC
(the Investment Manager) determines which securities will be purchased, held or
sold. The management fee is a percentage of the Fund's average daily net assets
that declines from 0.89% to 0.70% annually as the Fund's assets increase.

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

Other expenses in the amount of $1,364 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office expense,
employee compensation, employee health and retirement benefits, and certain
other expenses. Payment of these Fund and Board expenses is facilitated by a
company providing limited administrative services to the Fund and the Board.

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

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

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

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

- -  Class A $20.50

- -  Class B $21.50

- -  Class C $21.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
pays the Transfer Agent an annual asset-based fee at a rate of 0.05% of the
Fund's average daily net assets attributable to Class R4 shares. Prior to Dec.
11, 2006, the Fund paid the Transfer Agent an annual account-based fee of $18.50
per shareholder account.

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

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

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

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

The Fund has agreements with Ameriprise Financial Services, Inc. and RiverSource
Distributors, Inc. (collectively, the Distributor) for distribution and
shareholder services. Under a Plan and Agreement of Distribution pursuant to
Rule 12b-1, the Fund pays a fee at an annual rate of up to 0.25% of the Fund's
average daily net assets attributable to Class A and Class W shares and a fee at
an annual rate of up to 1.00% of the Fund's average daily net assets
attributable to Class B and Class C shares.

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

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

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.

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

 26 RIVERSOURCE ABSOLUTE RETURN CURRENCY AND INCOME FUND -- 2007 SEMIANNUAL
REPORT


For the six months ended April 30, 2007, the Investment Manager and its
affiliates waived certain fees and expenses (excluding fees and expenses of
acquired funds), such that net expenses were 1.35% for Class A, 2.10% for Class
B, 2.10% for Class C, 1.09% for Class I and 1.30% for Class R4. Of these waived
fees and expenses, the transfer agency fees waived for Class R4 were $2, and the
management fees waived at the Fund level were $2,733. In addition, the
Investment Manager and its affiliates have agreed to waive certain fees and
expenses until Oct. 31, 2007, unless sooner terminated at the discretion of the
Board, such that net expenses (excluding fees and expenses of acquired funds),
will not exceed 1.47% for Class A, 2.23% for Class B, 2.23% for Class C, 1.12%
for Class I, 1.31% for Class R4 and 1.57% for Class W of the Fund's average
daily net assets.

During the six months ended April 30, 2007, the Fund's custodian and transfer
agency fees were reduced by $304 as a result of earnings and bank fee credits
from overnight cash balances. The Fund also pays custodian fees to Ameriprise
Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $9,795,115 and $7,826,544, respectively, for the six

7. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The Fund must maintain asset coverage for borrowings of at least 300%. The
agreement, which enables the Fund to participate with other RiverSource funds,
permits borrowings up to $500 million, collectively. Interest is charged to each
Fund based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund also
pays a commitment fee equal to its pro rata share of the amount of the credit
facility at a rate of 0.06% per annum. The Fund had no borrowings under the
facility outstanding during the six months ended April 30, 2007.

8. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

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

 30 RIVERSOURCE ABSOLUTE RETURN CURRENCY AND INCOME FUND -- 2007 SEMIANNUAL
REPORT


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

As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and various
Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and
whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. AEFC also agreed to retain an independent
distribution consultant to assist in developing a plan for distribution of all
disgorgement and civil penalties ordered by the SEC in accordance with various
undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

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

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

 6 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, RiverSource Emerging Markets Fund portfolio managers Julian Thompson and
Jules Mort of Threadneedle International Limited (Threadneedle) discuss the
Fund's results and positioning for the six months ended April 30, 2007.
Threadneedle, an indirect wholly-owned subsidiary of Ameriprise Financial, Inc.,
acts as the subadviser to the Fund.

Q: How did RiverSource Emerging Markets Fund perform for the period?

A: The Fund increased 18.95% for the six-month period ended April 30, 2007.
   The Fund underperformed its benchmark, the Morgan Stanley Capital
   International Emerging Markets Index (MSCI Index), which increased 20.27%.
   The Fund also underperformed its peer group, the Lipper Emerging Markets
   Funds Index, which increased 19.44% for the six-month time frame.

Q: What factors most significantly affected performance?

A: The Fund benefited from a greater-than-MSCI Index position in Latin America,
   which was the best performing region during the period. The Fund also
   benefited from having relatively low exposure to Asia, which was the worst
   performing area during the six-month period. Within these regions, the Fund's
   exposure to Brazil and Mexico was helpful, but low exposure to China and
   India offset some of that benefit.

   Within Latin America, the Fund's holding in Companhia Vale do Rio Doce, a
   Brazilian iron ore producer, was a major success. The company performed very
   strongly after its acquisition of Inco, the Canadian nickel producer.
   However, the Fund's holding in pulp producer Aracruz Celulose, also based in
   Brazil, turned in disappointing performance during the period.

   The financials and telecommunications sectors have been particularly strong
   areas of performance for the Fund. Notable successes include Garanti Bank in
   Turkey, China Merchants Bank in China and Partner Communications in Israel.
   The Fund's holding in Maxis Communications, a Malaysian mobile
   telecommunications operator, also added value to the Fund after the company
   received a takeover bid at a large premium.

QUESTIONS & ANSWERS

   Weak performers during the period include Bajaj Hindustan, an Indian sugar
   producer, and Suzlon Energy, a marker of wind turbines also based in India.
   Bajaj Hindustan was sold during the period as the sugar price weakened
   significantly. Prime Success International Group, a Hong Kong-based shoemaker
   with outlets in China, was also a poor performer following a profits warning.

   THE FUND BENEFITED FROM A GREATER-THAN-MSCI INDEX POSITION IN LATIN
   AMERICA, WHICH WAS THE BEST PERFORMING REGION DURING THE PERIOD.


Q: What changes did you make to the Fund?

A: We reduced the Fund's exposure to the energy sector because we do not see
   much potential earnings growth in the sector. The Fund had a significant
   overweight relative to the MSCI Index in the energy sector and now the Fund
   is significantly underweight. We reinvested money from the energy sector into
   the telecommunications sector. The Fund is now overweight in
   telecommunications relative to the MSCI Index. We believe that
   telecommunications stocks have been undervalued, so we added some wireless
   telecommunications holdings to the Fund's portfolio. We also added exposure
   to the information technology sector during the period.

   We sold the Fund's holding in a Mexican-based cement producer that has a lot
   of exposure to the U.S. housing market and to Spain, where there are also
   concerns about the outlook for the economy in general and the housing market
   in particular. We also removed a long-term holding in a Russian brewery
   stock, which has produced disappointing earnings figures recently. We reduced
   our stake in Samsung Electronics following disappointing first quarter
   results from the South Korean company. During the period we added Mexican
   mobile firm America Movil, which announced very strong first quarter results.

   WE REDUCED THE FUND'S EXPOSURE TO THE ENERGY SECTOR BECAUSE WE DO NOT SEE
   MUCH POTENTIAL EARNINGS GROWTH IN THE SECTOR.

QUESTIONS & ANSWERS

Q: How are you positioning the Fund in the coming months?

A: Interest rates have risen in a number of different countries -- including
   Mexico and India -- partly reflecting food price inflation, which tends to be
   a large component of the inflation basket in many emerging economies. But we
   remain cautiously optimistic about the outlook for emerging markets. We
   expect corporate earnings to grow by a still robust 15% or so -- albeit down
   from last year.

   The Fund remains overweight in Latin America, underweight in Asia and
   slightly less than neutral in Eastern Europe, the Middle East and Africa.

FUND EXPENSES EXAMPLE

(UNAUDITED)

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

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended April 30, 2007: +18.95%
     for Class A, +18.58% for Class B, +18.54% for Class C, +19.30% for Class I
     and +19.12% for Class R4.
(c)  In September 2006, the Board approved renaming Class Y as Class R4,
     terminating the shareholder servicing agreement, revising the fee structure
     under the transfer agent agreement from an account-based fee to an
     asset-based fee, and adopting a plan administration services agreement. In
     addition, the investment manager and its affiliates have contractually
     agreed to waive certain fees and to absorb certain expenses until Oct. 31,
     2007, unless sooner terminated at the discretion of the Fund's Board, such
     that net expenses, (excluding fees and expenses of acquired funds), before
     giving effect to any performance incentive adjustment, will not exceed
     1.64% for Class R4. Any amounts waived will not be reimbursed by the Fund.
     These changes were effective Dec. 11, 2006. If these changes had been in
     place for the entire six-month period ended April 30, 2007, the actual
     expenses paid for Class R4 would have been $9.07 and the hypothetical
     expenses paid for Class R4 would have been $8.35.

 20 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

(Unaudited as to April 30, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Global Series, Inc. and is registered under
the Investment Company Act of 1940 (as amended) as a diversified, open-end
management investment company. RiverSource Global Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Board. The Fund invests primarily in equity
securities of emerging markets companies.

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

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

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

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

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

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

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

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

The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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

                 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT  21


VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds generally contemplate the use of fair valuation in the
event that price quotations or valuations are not readily available, price
quotations or valuations from other sources are not reflective of market value
and thus deemed unreliable, or a significant event has occurred in relation to a
security or class of securities (such as foreign equities) that is not reflected
in price quotations or valuations from other sources. A fair value price is a
good faith estimate of the value of a security at a given point in time. Many
securities markets and exchanges outside the U.S. close prior to the close of
the New York Stock Exchange and therefore the closing prices for securities in
such markets or on such exchanges may not fully reflect events that occur after
such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, including utilizing a third party pricing service to determine these
fair values. These procedures take into account multiple factors, including
movements in the U.S. securities markets, to determine a good faith estimate
that reasonably reflects the current market conditions as of the close of the
New York Stock Exchange. Short-term securities maturing in more than 60 days
from the valuation date are valued at the market price or approximate market
value based on current interest rates; those maturing in 60 days or less are
valued at amortized cost.

ILLIQUID SECURITIES

At April 30, 2007, investments in securities included issues that are illiquid
which the Fund currently limits to 10% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at April 30, 2007 was
$8,662,798 representing 1.38% of net assets. These securities may be valued at
fair value according to procedures approved, in good faith, by the Board.
According to board guidelines, certain unregistered securities are determined to
be liquid and are not included within the 10% limitation specified above. Assets
are liquid if they can be sold or disposed of in the ordinary course of business
within seven days at approximately the value at which the asset is valued by the
Fund.

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

 22 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT


OPTION TRANSACTIONS

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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

FUTURES TRANSACTIONS

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

Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

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

                 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT  23


FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the statement of operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes. At April 30, 2007, foreign currency holdings consisted of
multiple denominations, primarily Taiwan dollars.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations.

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

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

 24 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT


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

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value, and requires additional disclosures
about fair-value measurements. The application of SFAS 157 is required for
fiscal years beginning after Nov. 15, 2007 and interim periods within those
fiscal years. The impact of SFAS 157 on the Fund's financial statements is being
evaluated.

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

DIVIDENDS TO SHAREHOLDERS

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

OTHER

Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date or upon receipt of
ex-dividend notification in the case of certain foreign securities. Interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments, LLC
(the Investment Manager) determines which securities will be purchased, held or
sold. The management fee is a percentage of the Fund's average daily net assets
that declines from 1.10% to 0.90% annually as the Fund's assets increase. The
fee may be adjusted upward or downward by a performance incentive adjustment
based on a comparison of the performance of Class A shares of the Fund to the
Lipper Emerging Markets Funds Index. In certain circumstances, the Board may
approve a change in the index. The maximum adjustment is 0.12% per year. If the
performance difference is less than 0.50%, the adjustment will be zero. The
adjustment increased the fee by $151,459 for the six months ended April 30,
2007.

The Investment Manager has a Subadvisory Agreement with Threadneedle
International Limited, an indirect wholly-owned subsidiary of Ameriprise
Financial, to subadvise the assets of the fund.

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

Other expenses in the amount of $3,137 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office expense,
employee compensation, employee health and retirement benefits, and certain
other expenses. Payment of these Fund and Board expenses is facilitated by a
company providing limited administrative services to the Fund and the Board.

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

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

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

 26 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT


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

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
will pay the Transfer Agent an annual asset-based fee of 0.05% of the Fund's
average daily net assets attributable to Class R4 shares. Prior to Dec. 11,
2006, the Fund paid the Transfer Agent an annual account-based fee of $17.50 per
shareholder account.

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

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

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

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

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

Sales charges received by the Distributor for distributing Fund shares were
$454,976 for Class A, $22,726 for Class B and $532 for Class C for the six
months ended April 30, 2007.

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

                 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT  27


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.

Effective Dec. 11, 2006, with the renaming of Class Y as Class R4, the
Investment Manager and its affiliates have agreed to waive certain fees and
expenses until Oct. 31, 2007, unless sooner terminated at the discretion of the
Board, such that net expenses (excluding fees and expenses of acquired funds),
before giving effect to any performance incentive adjustment, will not exceed
1.64% for Class R4.

During the six months ended April 30, 2007, the Fund's custodian and transfer
agency fees were reduced by $15,140 as a result of earnings and bank fee credits
from overnight cash balances. The Fund also pays custodian fees to Ameriprise
Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $375,054,354 and $394,313,965, respectively, for the six
months ended April 30, 2007. Realized gains and losses are determined on an
identified cost basis.

6. AFFILIATED MONEY MARKET FUND

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

7. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The Fund must maintain asset coverage for borrowings of at least 300%. The
agreement, which enables the Fund to participate with other RiverSource funds,
permits borrowings up to $500 million, collectively. Interest is charged to each
Fund based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund also
pays a commitment fee equal to its pro rata share of the amount of the credit
facility at a rate of 0.06% per annum. The Fund had no borrowings under the
facility outstanding during the six months ended April 30, 2007.

8. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

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

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

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

 30 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT


As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and various
Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and
whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. AEFC also agreed to retain an independent
distribution consultant to assist in developing a plan for distribution of all
disgorgement and civil penalties ordered by the SEC in accordance with various
undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

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

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

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

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

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

Nature, Extent and Quality of Services Provided by RiverSource and the
Subadviser: The Board analyzed various reports and presentations they had
received detailing the services performed by RiverSource and the Subadviser, as
well as their expertise, resources and capabilities. The Board specifically
considered many developments during the past year concerning the services
provided by RiverSource, including, in particular, the growing strength and
capabilities of many RiverSource offices and the increased investment and
resources dedicated to the Fund's operations, particularly in the areas of
trading systems, legal and compliance. Further, in connection with the Board's
evaluation of the overall package of services provided by RiverSource, the Board
considered the quality of the administrative, custody and transfer agency
services provided by RiverSource affiliates to the Fund. The Board also reviewed
the financial condition of RiverSource and the Subadviser, and each entity's
ability to carry out its

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

 38 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT


responsibilities under the Advisory Agreements. The Board also discussed the
acceptability of the terms of the Advisory Agreements (including the relatively
broad scope of services required to be performed by RiverSource and the
Subadviser). The Board concluded that the services being performed under the
Advisory Agreements were of a reasonably high quality.

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

Investment Performance: For purposes of evaluating the nature, extent and
quality of services provided under the Advisory Agreements, the Board carefully
reviewed the investment performance of the Fund. In this regard, the Board
considered: (i) detailed reports containing data prepared by an independent
organization showing, for various periods, the performance of the Fund, the
performance of a benchmark index, the percentage ranking of the Fund among its
comparison group and the net assets of the Fund; and (ii) a report detailing the
Fund's performance over various periods (including since inception), recent Fund
inflows (and outflows) and a comparison of the Fund's net assets from December
2006 to December 2005. The Board observed that the Fund's investment performance
met expectations. Additionally, the Board reviewed the performance of the
Subadviser and the overall "subadvised" strategy. They noted, in particular,
management's ongoing oversight and monitoring of the Subadviser's investment
process and performance.

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

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

                 RIVERSOURCE EMERGING MARKETS FUND -- 2007 SEMIANNUAL REPORT  39


The Board also considered the expected profitability of RiverSource and its
affiliates in connection with RiverSource providing investment management
services to the Fund. In this regard, they referred to a detailed profitability
report, discussing the profitability to RiverSource and Ameriprise Financial
from managing and operating the Fund, including data showing comparative
profitability over the last three years. The Board also considered the services
acquired by the investment manager through the use of commission dollars paid by
the Funds on portfolio transactions. The Board noted that the fees paid by the
Fund should permit the investment manager to offer competitive compensation to
its personnel, make necessary investments in its business and earn an
appropriate profit. The Board concluded that profitability levels were
reasonable.

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

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

</Table>

Bond ratings apply to underlying holdings of the Fund and not the Fund itself.
Whenever possible, the Standard and Poor's rating is used to determine the
credit quality of a security. Standard and Poor's rates the creditworthiness of
corporate bonds, with 15 categories, ranging from AAA (highest) to D (lowest).
Ratings from AA to CCC may be modified by the addition of a plus (+) or minus
(-) sign to show relative standing within the major rating categories. If
Standard and Poor's doesn't rate a security, then Moody's rating is used.
RiverSource Investments, LLC, the Fund's investment manager, rates a security
using an internal rating system when Moody's doesn't provide a rating.

There are risks associated with an investment in a bond fund, including credit
risk, interest rate risk, and prepayment and extension risk. See the Fund's
prospectus for information on these and other risks associated with the Fund. In
general, bond prices rise when interest rates fall and vice versa. This effect
is usually more pronounced for longer-term securities. Non-investment grade
securities, commonly called "high-yield" or "junk" bonds, generally have more
volatile prices and carry more risk to principal and income than investment
grade securities.

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

 6 RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Nic Pifer, portfolio manager for RiverSource Emerging Markets Bond Fund,
discusses the Fund's results and positioning for the six months ended April 30,
2007.

At April 30, 2007, approximately 72% of the Fund's shares were owned in
aggregate by affiliated funds-of-funds managed by RiverSource Investments, LLC
(RiverSource). As a result of asset allocation decisions by RiverSource, it is
possible RiverSource Emerging Markets Bond Fund may experience relatively large
purchases or redemptions from affiliated funds-of-funds (see page 29, Class I
capital share transactions for related activity during the most recent fiscal
period). RiverSource seeks to minimize the impact of these transactions by
structuring them over a reasonable period of time. RiverSource Emerging Markets
Bond Fund may experience increased expenses as it buys and sells securities as a
result of purchases or redemptions by affiliated funds-of-funds. For more
information on the Fund's expenses, see the discussions beginning on pages 11
and 27.

Q: How did RiverSource Emerging Markets Bond Fund perform for the six months
   ended April 30, 2007?

A: RiverSource Emerging Markets Bond Fund's Class A shares increased 7.25%
   (excluding sales charge) for the six months ended April 30, 2007. The Fund
   outperformed both its benchmark, the J.P. Morgan Emerging Markets Bond
   Index-Global (J.P. Morgan EMBI-Global), which increased 5.29%, and the Lipper
   Emerging Markets Debt Funds Index, representing the Fund's peer group, which
   increased 6.90%, during the same period.

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

A: The Fund portfolio's holdings of assets with average yields higher than the
   J.P. Morgan EMBI-Global was a primary contributor to the Fund's
   outperformance. Fund holdings of local currency-denominated sovereign bonds
   and U.S. dollar-denominated corporate bonds also contributed significantly to
   the Fund's outperformance during the semiannual period.

   Also benefiting the Fund's returns during the period was the movement of
   certain foreign currencies in which the Fund was invested. For example, the
   Brazilian real outperformed both the U.S. dollar and the J.P. Morgan EMBI-
   Global during the six-month period. Several other Latin American currencies
   also outpaced the Fund's benchmark index.

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

             RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT  7

QUESTIONS & ANSWERS

   A third factor contributing to the Fund's performance during the period was a
   decline in interest rates in Brazil and Colombia, where the Fund held sizable
   positions in local currency-denominated assets. As these bond markets
   rallied, the Fund's holdings there outperformed the J.P. Morgan EMBI-Global.

   Detracting somewhat from the Fund's results was the combined effect of
   holding a percentage of assets in cash and maintaining a duration shorter
   than that of the J.P. Morgan EMBI-Global during a period when U.S. Treasury
   rates rallied. We implemented this somewhat defensive duration strategy
   because we believed that U.S. Treasury rates had declined to levels that
   appeared too low. Rather than rising as we had anticipated though, rates
   continued to fall through the period. Duration is a measure of the Fund's
   sensitivity to interest rate changes.

Q: What changes did you make to the Fund's portfolio during the period and how
   is it currently positioned?

A: During the period, we gradually and opportunistically increased the
   portfolio's foreign currency exposure, especially in Brazil, Indonesia,
   Mexico and Colombia. We carried out this strategy in the context of a U.S.
   dollar that was depreciating against most of the major currencies during the
   semiannual period. Several emerging market currencies also benefitted from a
   robust investor risk appetite.

   Also, during the reporting period, we increased the Fund's allocation to
   corporate debt, as we saw attractive value in select corporate bonds. We
   particularly found opportunities to invest in certain corporate bonds within
   Brazil, Argentina and Kazakhstan.

   As of April 30, 2007, approximately 76% of the Fund's net assets were
   invested in sovereign debt and approximately 20% in corporate debt with the
   remainder in cash and cash equivalents. The Fund had its most significant
   allocations relative to the J.P. Morgan EMBI-Global in the bond markets of
   Colombia, Argentina, Uruguay, Dominican Republic, Jamaica and El Salvador.
   Conversely, it had its most modest exposures relative to the benchmark index
   in the bond markets of Venezuela, Malaysia, Turkey and Russia. The Fund had
   relatively neutral allocations compared to the benchmark index in the
   Philippines and Peru.

QUESTIONS & ANSWERS

   DURING THE PERIOD, WE GRADUALLY AND OPPORTUNISTICALLY INCREASED THE
   PORTFOLIO'S FOREIGN CURRENCY EXPOSURE, ESPECIALLY IN BRAZIL, INDONESIA,
   MEXICO AND COLOMBIA.


Q: What is the Fund's tactical view and strategy for the months ahead?

A: Based primarily on our value analysis, we continue to seek opportunities to
   invest in local currency-denominated sovereign bonds and U.S. dollar-
   denominated corporate bonds in emerging markets. At the same time, we have
   begun to see increased levels of corporate debt issuance, which means careful
   issue selection will likely become increasingly important in the months
   ahead.

   From a country perspective, we are monitoring opportunities in Indonesia, as
   it has recently been the beneficiary of strong economic growth and a healthy
   balance of payments. We believe there remains attractive relative value both
   in its local currency-denominated debt and in its U.S. dollar-denominated
   issues.

   Overall, emerging markets fundamentals are strong. Many developing countries
   have low budget deficits, healthy current account balances and their lowest
   debt load in ten years. With flexible exchange rates and lower reliance on
   international capital, many of the vulnerabilities that triggered past
   periods of volatility in the sector are less of an issue today.

   Three years of double-digit annual returns from investing in emerging markets
   likely suggest more modest returns for 2007, as we have already seen this
   year to date. Nonetheless, we believe more developing countries will continue
   to move into the emerging markets debt sector and seek access to capital
   markets, presenting new investment opportunities. As existing emerging
   markets countries continue to grow and rely less on debt denominated in U.S.
   dollars, local corporations will begin to use the capital markets. We expect
   that many existing emerging market countries will continue to deepen their
   local capital markets, which should present more liquid foreign currency
   investment opportunities to investors as well.

   FROM A COUNTRY PERSPECTIVE, WE ARE MONITORING OPPORTUNITIES IN INDONESIA,
   AS IT HAS RECENTLY BEEN THE BENEFICIARY OF STRONG ECONOMIC GROWTH AND A
   HEALTHY BALANCE OF PAYMENTS.

QUESTIONS & ANSWERS

   Using our top-down investment approach, we intend to continually re-evaluate
   the creditworthiness of each country, the strength of its economic policies
   and its fundamentals, and the attractiveness of its local interest rates, as
   we seek to identify countries, individual securities and local currency
   investments that present attractive relative value opportunities.

 10 RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE

(UNAUDITED)

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

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended April 30, 2007: +7.25%
     for Class A, +6.84% for Class B, +6.78% for Class C, +7.41% for Class I and
     +7.32% for Class R4.
(c)  In September 2006, the Board approved renaming Class Y as Class R4,
     terminating the shareholder servicing agreement, revising the fee structure
     under the transfer agent agreement from an account-based fee to an
     asset-based fee, and adopting a plan administration services agreement.
     These changes were effective Dec. 11, 2006. In addition, the investment
     manager and its affiliates have contractually agreed to waive certain fees
     and to absorb certain expenses until Oct. 31, 2007, unless sooner
     terminated at the discretion of the Fund's Board, such that net expenses
     (excluding fees and expenses of acquired funds), will not exceed 1.29% for
     Class R4. Any amounts waived will not be reimbursed by the Fund. If these
     changes had been in place for the entire six-month period ended April 30,
     2007, the actual expenses paid for Class R4 would have been $6.63 and the
     hypothetical expenses paid for Class R4 would have been $6.46.
(d)  The actual values and expenses paid are not presented because Class W does
     not have a full six months of history. The inception date for Class W is

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to April 30, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Global Series, Inc. and is registered under
the Investment Company Act of 1940 (as amended) as a non-diversified, open-end
management investment company. RiverSource Global Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Board. The Fund invests primarily in fixed income
securities of emerging market issuers. On Feb. 9, 2006, Ameriprise Financial,
Inc. (Ameriprise Financial) invested $10,045,040* in the Fund (996,000 shares
for Class A, 1,000 shares for Class B, 1,000 shares for Class C, 5,504** shares
for Class I and 1,000 shares for Class Y), which represented the initial capital
for each class at $10 per share. Shares of the Fund were first offered to the
public on Feb. 16, 2006.

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

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

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

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

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

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

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

fees, plan administration fees) differ among classes. Income, expenses (other
than class specific expenses) and realized and unrealized gains or losses on
investments are allocated to each class of shares based upon its relative net
assets.

 22 RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT


The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds generally contemplate the use of fair valuation in the
event that price quotations or valuations are not readily available, price
quotations or valuations from other sources are not reflective of market value
and thus deemed unreliable, or a significant event has occurred in relation to a
security or class of securities (such as foreign equities) that is not reflected
in price quotations or valuations from other sources. A fair value price is a
good faith estimate of the value of a security at a given point in time. Many
securities markets and exchanges outside the U.S. close prior to the close of
the New York Stock Exchange and therefore the closing prices for securities in
such markets or on such exchanges may not fully reflect events that occur after
such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, including utilizing a third party pricing service to determine these
fair values. These procedures take into account multiple factors, including
movements in the U.S. securities markets, to determine a good faith estimate
that reasonably reflects the current market conditions as of the close of the
New York Stock Exchange. 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.

SECURITIES PURCHASED ON A FORWARD-COMMITMENT BASIS

Delivery and payment for securities that have been purchased by the Fund on a
forward-commitment basis, including when-issued securities and other forward-
commitments, can take place one month or more after the transaction date. During
this period, such securities are subject to market fluctuations, and they may
affect the Fund's net assets the same as owned securities. The Fund designates
cash or liquid securities at least equal to the amount of its
forward-commitments. At April 30, 2007, the Fund had no outstanding
forward-commitments.

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

            RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT  23


The Fund also enters into transactions to sell purchase commitments to third
parties at current market values and concurrently acquires other purchase
commitments for similar securities at later dates. As an inducement for the Fund
to "roll over" its purchase commitments, the Fund receives negotiated amounts in
the form of reductions of the purchase price of the commitment.

OPTION TRANSACTIONS

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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

FUTURES TRANSACTIONS

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

Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the statement of operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes. At April 30, 2007, foreign currency holdings were comprised
of Indonesian rupiahs and Mexican pesos.

The Fund may enter into forward foreign currency exchange contracts to produce
incremental earnings, for operational purposes, or to protect against adverse
exchange rate fluctuation. The net U.S. dollar value of foreign currency
underlying all contractual commitments held by the Fund and the resulting
unrealized appreciation or depreciation are determined using foreign currency
exchange rates from an independent pricing service. The Fund is subject to the
credit risk that the other party will not complete its contract obligations.

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.

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

            RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT  25


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

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value, and requires additional disclosures
about fair-value measurements. The application of SFAS 157 is required for
fiscal years beginning after Nov. 15, 2007 and interim periods within those
fiscal years. The impact of SFAS 157 on the Fund's financial statements is being
evaluated.

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

DIVIDENDS TO SHAREHOLDERS

Dividends from net investment income, declared daily and payable monthly, when
available, are reinvested in additional shares of the Fund at net asset value or
payable in cash. Capital gains, when available, are distributed along with the
last income dividend of the calendar year.

OTHER

Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date or upon receipt of
ex-dividend notification in the case of certain foreign securities. Interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments, LLC
(the Investment Manager) determines which securities will be purchased, held or
sold. The management fee is a percentage of the Fund's average daily net assets
that declines from 0.72% to 0.52% annually as the Fund's assets increase.

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

Other expenses in the amount of $765 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office expense,
employee compensation, employee health and retirement benefits, and certain
other expenses. Payment of these Fund and Board expenses is facilitated by a
company providing limited administrative services to the Fund and the Board.

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

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

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

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

- -  Class A $20.50

- -  Class B $21.50

- -  Class C $21.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
pays the Transfer Agent an annual asset-based fee at a rate of 0.05% of the
Fund's average daily net assets attributable to Class R4 shares. Prior to Dec.
11, 2006, the Fund paid the Transfer Agent an annual account-based fee of $18.50
per shareholder account.

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

            RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT  27


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

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

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

The Fund has agreements with Ameriprise Financial Services, Inc. and RiverSource
Distributors, Inc. (collectively, the Distributor) for distribution and
shareholder services. Under a Plan and Agreement of Distribution pursuant to
Rule 12b-1, the Fund pays a fee at an annual rate of up to 0.25% of the Fund's
average daily net assets attributable to Class A and Class W shares and a fee at
an annual rate of up to 1.00% of the Fund's average daily net assets
attributable to Class B and Class C shares.

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

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

Sales charges received by the Distributor for distributing Fund shares were
$12,758 for Class A and $731 for Class B for the six months ended April 30,
2007.

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

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

 28 RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT


For the six months ended April 30, 2007, the Investment Manager and its
affiliates waived certain fees and expenses (excluding fees and expenses of
acquired funds), such that net expenses were 1.34% for Class A, 2.12% for Class
B, 2.10% for Class C, 1.01% for Class I and 1.28% for Class R4. Of these waived
fees and expenses, the management fees waived at the Fund level were $1,055. In
addition, the Investment Manager and its affiliates have agreed to waive certain
fees and expenses until Oct. 31, 2007, unless sooner terminated at the
discretion of the board, such that net expenses (excluding fees and expenses of
acquired funds), will not exceed 1.45% for Class A, 2.21% for Class B, 2.21% for
Class C, 1.10% for Class I, 1.29% for Class R4 and 1.45% for Class W of the

6. AFFILIATED MONEY MARKET FUND

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

7. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The Fund must maintain asset coverage for borrowings of at least 300%. The
agreement, which enables the Fund to participate with other RiverSource funds,
permits borrowings up to $500 million, collectively. Interest is charged to each
Fund based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund also
pays a commitment fee equal to its pro rata share of the amount of the credit
facility at a rate of 0.06% per annum. The Fund had no borrowings under the
facility outstanding during the six months ended April 30, 2007.

8. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

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

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

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

            RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT  31


As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and various
Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and
whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. AEFC also agreed to retain an independent
distribution consultant to assist in developing a plan for distribution of all
disgorgement and civil penalties ordered by the SEC in accordance with various
undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

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

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

            RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT  39


APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

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

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

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

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

 40 RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT


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

Investment Performance: For purposes of evaluating the nature, extent and
quality of services provided under the IMS Agreement, the Board carefully
reviewed the investment performance of the Fund. In this regard, the Board
considered: (i) detailed reports containing data prepared by an independent
organization showing, for various periods, the performance of the Fund, the
performance of a benchmark index, the percentage ranking of the Fund among its
comparison group and the net assets of the Fund; and (ii) a report detailing the
Fund's performance over various periods (including since inception), recent Fund
inflows (and outflows) and a comparison of the Fund's net assets from December
2006 to December 2005. The Board observed that the Fund's investment performance
met expectations.

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

The Board also considered the expected profitability of RiverSource and its
affiliates in connection with RiverSource providing investment management
services to the Fund. In this regard, they referred to a detailed profitability
report, discussing the profitability to RiverSource and Ameriprise Financial
from managing and operating the Fund, including data showing comparative
profitability over the last three years. The Board also considered the services
acquired by the investment manager through the use of commission dollars paid by
the Funds on portfolio transactions. The Board noted that the fees paid by the
Fund should permit the investment manager to offer competitive compensation to
its personnel, make necessary investments in its business and earn an
appropriate profit. The Board concluded that profitability levels were
reasonable.

            RIVERSOURCE EMERGING MARKETS BOND FUND -- 2007 SEMIANNUAL REPORT  41


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

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

PROXY VOTING

There are risks associated with an investment in a bond fund, including credit
risk, interest rate risk, and prepayment and extension risk. See the Fund's
prospectus for information on these and other risks associated with the Fund. In
general, bond prices rise when interest rates fall and vice versa. This effect
is usually more pronounced for longer-term securities. Non-investment grade
securities, commonly called "high-yield" or "junk" bonds, generally have more
volatile prices and carry more risk to principal and income than investment
grade securities.

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

 6 RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Nic Pifer, portfolio manager for RiverSource Global Bond Fund, discusses
the Fund's results and positioning for the semiannual period ended April 30,
2007.

At April 30, 2007, approximately 34% of the Fund's shares were owned in
aggregate by affiliated funds-of-funds managed by RiverSource Investments, LLC
(RiverSource). As a result of asset allocation decisions by RiverSource, it is
possible RiverSource Global Bond Fund may experience relatively large purchases
or redemptions from affiliated funds-of-funds (see page 38, Class I capital
share transactions for related activity during the most recent fiscal period).
RiverSource seeks to minimize the impact of these transactions by structuring
them over a reasonable period of time. RiverSource Global Bond Fund may
experience increased expenses as it buys and sells securities as a result of
purchases or redemptions by affiliated funds-of-funds. For more information on
the Fund's expenses, see the discussions beginning on pages 11 and 35.

Q: How did RiverSource Global Bond Fund perform for the semiannual period?

A: RiverSource Global Bond Fund's Class A shares increased 3.92% (excluding
   sales charge) for the six months ended April 30, 2007. The Fund outperformed
   its benchmark, the Lehman Brothers Global Aggregate Index (Lehman Global
   Index), which increased 3.54%. The Fund also outperformed the Lipper Global
   Income Funds Index, representing the Fund's peer group, which increased 3.76%
   during the same period.

   RELATIVE TO THE LEHMAN GLOBAL INDEX, THE FUND BENEFITED MOST FROM
   EFFECTIVE CURRENCY POSITIONING.


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

A: Currency markets had the most positive impact on the Fund's absolute
   performance, as the U.S. dollar fell 2.48% on a trade-weighted basis for the
   six months ended April 30, 2007. As the value of the U.S. dollar decreases,
   the dollar value of foreign investments typically increases and vice versa.
   Offsetting the positive effect of the falling U.S. dollar to some extent was
   the impact of static to rising bond yields in the major markets, which
   partially negated the coupon income from the bonds themselves. Remember,
   there is an inverse relationship between bond prices and interest rate
   movements, so that bond prices decline when interest rates rise and increase
   when interest rates fall. Global bonds produced only modestly positive
   returns in local currency terms for the semiannual period overall.

QUESTIONS & ANSWERS

   Relative to the Lehman Global Index, the Fund benefited most from effective
   currency positioning. The Fund benefited most from its significant weightings
   in the euro, other European currencies, and the "dollar bloc" currencies as
   well as its modest exposure to the Japanese yen. The U.S. dollar weakened vs.
   the euro, the British pound, the New Zealand dollar and the Australian dollar
   and strengthened vs. the Japanese yen. The Fund's positioning in the Canadian
   dollar and the U.S. dollar detracted somewhat.

   On a sector basis, the Fund benefited from its exposure to high yield
   corporate bonds, where the Fund had an emphasis on comparatively high quality
   issues and bank loans compared to the Lehman Global Index. The Fund also
   benefited from its allocation to and issue selection within mortgage-backed
   securities and commercial mortgage-backed securities (CMBS), especially
   during the first months of the fiscal period. Modest exposure to the
   investment grade corporate bond sector relative to the Lehman Global Index
   further boosted Fund returns, particularly in late February and early March
   of 2007 when the equity markets declined rather sharply. Of course, the
   majority of the Fund's holdings remained in the government bond sector. The
   Fund also benefited significantly from the payment it received during the
   period as part of the settlement of the WorldCom class action case.

   Detracting modestly from the Fund's results relative to the Lehman Global
   Index was its yield curve positioning in the Japanese bond market, that is,
   the way the Fund was positioned to respond to changes in short-term vs.
   long-term interest rates. Japan's fixed income yield curve flattened during
   the period while the Fund had maintained a bias for a slight steepening.

   We maintained the Fund's duration, a principal measure of interest rate risk,
   shorter than that of the Lehman Global Index for much of the semiannual
   period, based on relative valuation analysis. The Fund's short duration
   positioning had a rather neutral effect on results because global bond yields
   remained static in the U.S. and Canada, moved up in core Europe and the U.K.,
   and declined in Japan.

QUESTIONS & ANSWERS

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

A: As the euro and other European currencies rallied during the period vs. the
   U.S. dollar, we took the opportunity to pare back on the Fund's position in
   these European currencies, moving from a sizable exposure to a neutral
   allocation compared to the Lehman Global Index. We redeployed most of those
   assets into the U.S. dollar.

   We slightly reduced the Fund's positions in AAA-rated CMBS, pass-through
   mortgages, asset-backed securities and European covered bonds (bonds that are
   covered by a pool of assets collateralizing the bonds), while still
   maintaining significant exposure to these sectors. We modestly increased the
   Fund's allocation to high yield corporate bonds, primarily in the form of
   high yield bank loans. We slightly shortened the Fund's duration relative to
   the Lehman Global Index, primarily in the U.S. bond market.

   WE INTEND TO MAINTAIN THE FUND'S GENERALLY CONSERVATIVE PROFILE, A STANCE
   THAT WE BELIEVE WILL CONTINUE TO BENEFIT THE FUND DURING THE COMING
   MONTHS.


Q: What is the Fund's tactical view and strategy for the months ahead?

A: The semiannual period was characterized most by a cyclical divergence
   between the U.S. and the other major developed nations, with U.S. economic
   growth slowing, European economies growing rather robustly, and the Japanese
   economy growing at a near-trend rate. As a result, the U.S. Federal Reserve
   Board (the Fed) was on hold during the period, maintaining its targeted
   federal funds rate at 5.25%. The Canadian and Australian central banks were
   also on hold during the period. The European Central Bank as well as the
   U.K., Swedish and New Zealand central banks each raised its respective
   interest rates twice more during the period. Norway's central bank raised its
   interest rates three times during the period. The Bank of Japan raised its
   interest rates only one more time.

QUESTIONS & ANSWERS

   Going forward, we believe the global economy as a whole is moving toward a
   trend-like rate of growth. We do expect some rebalancing of growth rates in
   the major economies, with the U.S. economy anticipated to bounce back in the
   second half of the year as the impact of the housing slowdown dissipates and
   with the European economy expected to moderate as the impact of higher
   interest rates takes effect. We expect the Fed to remain on hold for an
   extended period of time, the European Central Bank to finish its tightening
   by late 2007, and the Bank of Japan to perhaps raise rates twice more before
   ending its tightening cycle in early 2008. Given this rather static
   environment for bonds, we believe we are entering a period of largely narrow
   moves in bond yields.

   Given our benign view for the major central banks, we feel comfortable with
   the Fund's current positioning. We intend to maintain the Fund's generally
   conservative profile, a stance that we believe will continue to benefit the
   Fund during the coming months.

   As always, we constantly monitor the market for changing conditions and
   regularly re-evaluate the Fund's duration, sector, country, yield curve, and
   currency positioning in an effort to seek an attractive trade-off between
   risk and potential return. Our sector teams remain focused on careful
   individual security selection, as we continue to seek opportunities to
   capitalize on attractively valued bonds.

 10 RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE

(UNAUDITED)

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

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended April 30, 2007: +3.92%
     for Class A, +3.48% for Class B, +3.50% for Class C, +3.98% for Class I and
     +4.02% for Class R4.
(c)  In September 2006, the Board approved renaming Class Y as Class R4,
     terminating the shareholder servicing agreement, revising the fee structure
     under the transfer agent agreement from an account-based fee to an
     asset-based fee, and adopting a plan administration services agreement.
     These changes were effective Dec. 11, 2006. In addition, the investment
     manager and its affiliates have contractually agreed to waive certain fees
     and to absorb certain expenses until Oct. 31, 2007, unless sooner
     terminated at the discretion of the Fund's Board, such that net expenses,
     (excluding fees and expenses of acquired funds), will not exceed 1.08% for
     Class R4. Any amounts waived will not be reimbursed by the Fund. If these
     changes had been in place for the entire six-month period ended April 30,
     2007, the actual and hypothetical expenses paid for Class R4 would have
     been the same as those expenses presented in the table above.
(d)  The actual values and expenses paid are not presented because Class W does
     not have a full six months of history. The inception date of Class W is
     Dec. 1, 2006.

NOTES TO INVESTMENTS IN SECURITIES

(a)  Securities are valued by procedures described in Note 1 to the financial
     statements.

(b)  At April 30, 2007, the cost of securities purchased, including interest
     purchased, on a when-issued and/or other forward-commitment basis was
     $4,827,814.

(c)  Foreign security values are stated in U.S. dollars. For debt securities,
     principal amounts are denominated in U.S. dollar currency unless otherwise
     noted.

(d)  Represents a security sold under Rule 144A, which is exempt from
     registration under the Securities Act of 1933, as amended. This security
     has been determined to be liquid under guidelines established by the Fund's
     Board of Directors. These securities may be resold in transactions exempt
     from registration, normally to qualified institutional buyers. At April 30,
     2007, the value of these securities amounted to $21,433,675 or 4.3% of net
     assets.

(e)  Interest only represents securities that entitle holders to receive only
     interest payments on the underlying mortgages. The yield to maturity of an
     interest only is extremely sensitive to the rate of principal payments on
     the underlying mortgage assets. A rapid (slow) rate of principal repayments
     may have an adverse (positive) effect on yield to maturity. The principal
     amount shown is the notional amount of the underlying mortgages. Interest
     rate disclosed represents yield based upon the estimated timing and amount
     of future cash flows at April 30, 2007.

(f)  Mortgage-backed securities represent direct or indirect participations in,
     or are secured by and payable from, mortgage loans secured by real
     property, and include single- and multi-class pass-through securities and
     collateralized mortgage obligations. These securities may be issued or
     guaranteed by U.S. government agencies or instrumentalities, or by private
     issuers, generally originators and investors in mortgage loans, including
     savings associations, mortgage bankers, commercial banks, investment
     bankers and special purpose entities. The maturity dates shown represent
     the original maturity of the underlying obligation. Actual maturity may
     vary based upon prepayment activity on these obligations. Unless otherwise
     noted, the coupon rates presented are fixed rates.

(h)  Interest rate varies either based on a predetermined schedule or to reflect
     current market conditions; rate shown is the effective rate on April 30,
     2007.

(k)  Senior loans have rates of interest that float periodically based primarily
     on the London Interbank Offered Rate ("LIBOR") and other short-term rates.
     Remaining maturities of senior loans may be less than the stated maturities
     shown as a result of contractual or optional prepayments by the borrower.
     Such prepayments cannot be predicted with certainty.

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to April 30, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Global Series, Inc. and is registered under
the Investment Company Act of 1940 (as amended) as a non-diversified, open-end
management investment company. RiverSource Global Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Board. The Fund invests primarily in debt
obligations of U.S. and foreign issuers.

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

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

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

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

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

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

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

Effective Dec. 1, 2006, the Fund offers an additional class of shares, Class W,
offered through qualifying discretionary accounts. Class W shares are sold
without a front-end sales charge or CDSC.

At April 30, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 34% of the total outstanding Fund shares.

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

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

 30 RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT


The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds generally contemplate the use of fair valuation in the
event that price quotations or valuations are not readily available, price
quotations or valuations from other sources are not reflective of market value
and thus deemed unreliable, or a significant event has occurred in relation to a
security or class of securities (such as foreign equities) that is not reflected
in price quotations or valuations from other sources. A fair value price is a
good faith estimate of the value of a security at a given point in time. Many
securities markets and exchanges outside the U.S. close prior to the close of
the New York Stock Exchange and therefore the closing prices for securities in
such markets or on such exchanges may not fully reflect events that occur after
such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, including utilizing a third party pricing service to determine these
fair values. These procedures take into account multiple factors, including
movements in the U.S. securities markets, to determine a good faith estimate
that reasonably reflects the current market conditions as of the close of the
New York Stock Exchange. Short-term securities maturing in more than 60 days
from the valuation date are valued at the market price or approximate market
value based on current interest rates; those maturing in 60 days or less are
valued at amortized cost.

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

                      RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT  31


SECURITIES PURCHASED ON A FORWARD-COMMITMENT BASIS

Delivery and payment for securities that have been purchased by the Fund on a
forward-commitment basis, including when-issued securities and other forward-
commitments, can take place one month or more after the transaction date. During
this period, such securities are subject to market fluctuations, and they may
affect the Fund's net assets the same as owned securities. The Fund designates
cash or liquid securities at least equal to the amount of its
forward-commitments. At April 30, 2007, the Fund has entered into outstanding
when-issued securities of $3,395,149 and other forward-commitments of
$1,432,665.

The Fund also enters into transactions to sell purchase commitments to third
parties at current market values and concurrently acquires other purchase
commitments for similar securities at later dates. As an inducement for the Fund
to "roll over" its purchase commitments, the Fund receives negotiated amounts in
the form of reductions of the purchase price of the commitment.

OPTION TRANSACTIONS

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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

FUTURES TRANSACTIONS

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

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

 32 RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT


Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the statement of operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes. At April 30, 2007, foreign currency holdings consisted of
multiple denominations, primarily European monetary units.

The Fund may enter into forward foreign currency exchange contracts to produce
incremental earnings, for operational purposes, or to protect against adverse
exchange rate fluctuation. The net U.S. dollar value of foreign currency
underlying all contractual commitments held by the Fund and the resulting
unrealized appreciation or depreciation are determined using foreign currency
exchange rates from an independent pricing service. The Fund is subject to the
credit risk that the other party will not complete its contract obligations.

CMBS TOTAL RETURN SWAP TRANSACTIONS

The Fund may enter into swap agreements to earn the total return on a specified
security or index of fixed income securities. CBMS total return swaps are
bilateral financial contracts designed to replicate synthetically the total
returns of collateralized mortgage-backed securities. Under the terms of the
swaps, the Fund either receives or pays the total return on a reference security
or index applied to a notional principal amount. In return, the Fund agrees to
pay or receive from the counterparty a floating rate, which is reset
periodically based on short-term interest rates, applied to the same notional
amount.

The notional amounts of swap contracts are not recorded in the financial
statements. Swaps are valued daily, and the change in value is recorded as
unrealized appreciation (depreciation) until the termination of the swap, at
which time realized gain (loss) is recorded. Payments received or made are
recorded as realized gains (losses).

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

                      RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT  33


Swap agreements may be subject to liquidity risk, which exists when a particular
swap is difficult to purchase or sell. It may not be possible for the Fund to
initiate a transaction or liquidate a position at an advantageous time or price,
which may result in significant losses. Total return swaps are subject to the
risk that the counterparty will default on its obligation to pay net amounts due
to the Fund.

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

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

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value, and requires additional disclosures
about fair-value measurements. The application of SFAS 157 is required for
fiscal years beginning after Nov. 15, 2007 and interim periods within those
fiscal years. The impact of SFAS 157 on the Fund's financial statements is being
evaluated.

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

 34 RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT


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

DIVIDENDS TO SHAREHOLDERS

Dividends from net investment income, declared and paid each calendar quarter,
when available, are reinvested in additional shares of the Fund at net asset
value or payable in cash. Capital gains, when available, are distributed along
with the last income dividend of the calendar year.

OTHER

Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date or upon receipt of
ex-dividend notification in the case of certain foreign securities. Interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments, LLC
(the Investment Manager) determines which securities will be purchased, held or
sold. The management fee is a percentage of the Fund's average daily net assets
that declines from 0.72% to 0.52% annually as the Fund's assets increase.

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

Other expenses in the amount of $2,135 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.

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

                      RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT  35


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

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

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

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

- -  Class A $20.50

- -  Class B $21.50

- -  Class C $21.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
pays the Transfer Agent an annual asset-based fee at a rate of 0.05% of the
Fund's average daily net assets attributable to Class R4 shares. Prior to Dec.
11, 2006, the Fund paid the Transfer Agent an annual account-based fee of $18.50
per shareholder account.

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

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

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

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

 36 RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT


The Fund has agreements with Ameriprise Financial Services, Inc. and RiverSource
Distributors, Inc. (collectively, the Distributor) for distribution and
shareholder services. Under a Plan and Agreement of Distribution pursuant to
Rule 12b-1, the Fund pays a fee at an annual rate of up to 0.25% of the Fund's
average daily net assets attributable to Class A and Class W shares and a fee at
an annual rate of up to 1.00% of the Fund's average daily net assets
attributable to Class B and Class C shares.

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

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

Sales charges received by the Distributor for distributing Fund shares were
$139,486 for Class A, $30,083 for Class B and $1,102 for Class C for the six
months ended April 30, 2007.

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

For the six months ended April 30, 2007, the Investment Manager and its
affiliates waived certain fees and expenses (excluding fees and expenses of
acquired funds), such that net expenses were 1.25% for Class A, 2.02% for Class
B, 2.01% for Class C, 1.08% for Class R4 and 1.26% for Class W. Of these waived
fees and expenses, the transfer agency fees waived for Class A, Class B, Class
C, Class R4 and Class W were $154,442, $35,047, $1,634, $40 and $384,
respectively, and the management fees waived at the Fund level were $165. In
addition, the Investment Manager and its affiliates have agreed to waive certain
fees and expenses until Oct. 31, 2007, unless sooner terminated at the
discretion of the Board, such that net expenses (excluding fees and expenses of
acquired funds), will not exceed 1.25% for Class A, 2.02% for Class B, 2.02% for
Class C, 0.90% for Class I, 1.08% for Class R4 and 1.26% for Class W of the
Fund's average daily net assets.

During the six months ended April 30, 2007, the Fund's custodian and transfer
agency fees were reduced by $9,737 as a result of earnings and bank fee credits
from overnight cash balances. The Fund also pay custodian fees to Ameriprise
Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $178,768,517 and $188,155,979, respectively, for the six
months ended April 30, 2007. Realized gains and losses are determined on an
identified cost basis.

Income from securities lending amounted to $6,589 for the six months ended April
30, 2007. 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.

4. CAPITAL SHARE TRANSACTIONS

8. 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.

9. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The Fund must maintain asset coverage for borrowings of at least 300%. The
agreement, which enables the Fund to participate with other RiverSource funds,
permits borrowings up to $500 million, collectively. Interest is charged to each
Fund based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund also
pays a commitment fee equal to its pro rata share of the amount of the credit
facility at a rate of 0.06% per annum. The Fund had no borrowings under the
facility outstanding during the six months ended April 30, 2007.

10. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$6,599,145 at Oct. 31, 2006, that if not offset by capital gains will expire as
follows:

<Table>
<Caption>
   2010                        2011
                          
$6,100,374                   $498,771
</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.

11. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc., was filed in the
United States District Court for the District of Arizona. The plaintiffs allege
that 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.

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

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

                      RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT  41


As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and various
Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and
whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. AEFC also agreed to retain an independent
distribution consultant to assist in developing a plan for distribution of all
disgorgement and civil penalties ordered by the SEC in accordance with various
undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

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

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

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

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

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

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

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

 50 RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT


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

Investment Performance: For purposes of evaluating the nature, extent and
quality of services provided under the IMS Agreement, the Board carefully
reviewed the investment performance of the Fund. In this regard, the Board
considered: (i) detailed reports containing data prepared by an independent
organization showing, for various periods, the performance of the Fund, the
performance of a benchmark index, the percentage ranking of the Fund among its
comparison group and the net assets of the Fund; and (ii) a report detailing the
Fund's performance over various periods (including since inception), recent Fund
inflows (and outflows) and a comparison of the Fund's net assets from December
2006 to December 2005. The Board observed that the Fund's investment performance
met expectations.

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

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

                      RIVERSOURCE GLOBAL BOND FUND -- 2007 SEMIANNUAL REPORT  51


The Board also considered the expected profitability of RiverSource and its
affiliates in connection with RiverSource providing investment management
services to the Fund. In this regard, they referred to a detailed profitability
report, discussing the profitability to RiverSource and Ameriprise Financial
from managing and operating the Fund, including data showing comparative
profitability over the last three years. The Board also considered the services
acquired by the investment manager through the use of commission dollars paid by
the Funds on portfolio transactions. The Board noted that the fees paid by the
Fund should permit the investment manager to offer competitive compensation to
its personnel, make necessary investments in its business and earn an
appropriate profit. The Board concluded that profitability levels were
reasonable.

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

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

QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, RiverSource Global Equity Fund portfolio managers Dominic Rossi and
Stephen Thornber of Threadneedle International Limited (Threadneedle) discuss
the Fund's results and positioning for the six-month period ended April 30,
2007. Threadneedle, an indirect wholly-owned subsidiary of Ameriprise Financial,
Inc., acts as the subadviser to the Fund.

Q: How did RiverSource Global Equity Fund perform for the period?

A: The Fund increased 11.66% (Class A shares excluding sales charge) for the
   six-month period ended April 30, 2007. The Fund underperformed its benchmark,
   the Morgan Stanley Capital International All Country World Index (MSCI
   Index), which increased 12.75% for the period. The Fund also underperformed
   the Lipper Global Funds Index, representing the Fund's peer group, which
   increased 11.90% over the same time frame.

Q: What factors most significantly affected performance?

A: The Fund's overweight in Japan relative to the MSCI Index was the largest
   detractor to performance during the six-month period. The Bank of Japan was
   very slow to raise interest rates and domestic Japanese institutions shunned
   the market. The Fund's exposure to Japanese financials particularly hurt
   performance with Tokai Tokyo Securities one of the largest detractors. Stock
   selection in Europe was a slight drag on performance as Carphone Warehouse
   Group in the U.K. performed poorly when Vodafone announced an exclusive
   distribution deal with one of Carphone's competitors. The Fund continues to
   hold the stock believing any setbacks are only temporary.

   The Fund's iron ore and copper positions in Latin America were key
   contributors to performance for the period as were the Fund's paper and pulp
   holdings in Latin America. Also contributing positively was South African
   retailer Massmart Holdings, which saw very strong sales figures that boosted
   the stock price. The company is one of the most profitable retailers in the
   world. Lastly, the Fund's positions in refining added value during the
   period. U.S. oil refiner Valero Energy, European-based oil refiner Petroplus
   Holdings, and Marathon Oil were all strong performers during the period.

   THE FUND'S IRON ORE AND COPPER POSITIONS IN LATIN AMERICA WERE KEY
   CONTRIBUTORS TO PERFORMANCE FOR THE PERIOD AS WERE THE FUND'S PAPER AND
   PULP HOLDINGS IN LATIN AMERICA.

QUESTIONS & ANSWERS



Q: What changes did you make to the Fund during the six-month period?

A: One of the most significant changes we made during the period was
   eliminating the Fund's overweight in Japan. We brought the Fund's weighting
   down to neutral because we now believe we can find better value elsewhere in
   the world. We still see a lot of potential in Japan and think the market is
   undervalued; however, we are waiting for the Japanese stock market to reflect
   the country's positive corporate growth and record profits.

   Additionally, we increased the Fund's exposure to Latin America and are
   adding to the Fund's U.S. exposure on a stock selection basis including eBay
   and Bowater. However, the U.S. remains the Fund's biggest underweight. During
   the period, we sold out of the Fund's positions in U.S. homebuilders such as
   DR Horton and Hovnanian when we saw the housing market continue to fall.
   ONE OF THE MOST SIGNIFICANT CHANGES WE MADE DURING THE PERIOD WAS
   ELIMINATING THE FUND'S OVERWEIGHT IN JAPAN.


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

A: We remain optimistic about the outlook for equities. The background for
   global equities remains positive. Valuations are attractive, corporate
   results have been encouraging, and we expect recent robust merger and
   acquisition activity levels to continue. However, we recognize that equities
   have enjoyed a very strong run and that inflationary expectations are
   beginning to rise around the globe. We are beginning to anticipate some of
   the headwinds that the markets may encounter in the second half of the year,
   such as the impact of the weak dollar and higher interest rates. Thus, we are
   tempering our optimism with some caution.

FUND EXPENSES EXAMPLE

(UNAUDITED)

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

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended April 30, 2007: +11.66%
     for Class A, +11.23% for Class B, +11.29% for Class C and +11.56% for Class
     R4.
(c)  The actual values and expenses paid are not presented because Class R2,
     Class R3, Class R5 and Class W do not have a full six months of history.
     The inception date of Class R2, Class R3 and Class R5 is Dec. 11, 2006. The
     inception date of Class W is Dec. 1, 2006.
(d)  In September 2006, the Board approved renaming Class Y as Class R4,
     terminating the shareholder servicing agreement, revising the fee structure
     under the transfer agent agreement from an account-based fee to an
     asset-based fee, and adopting a plan administration services agreement. In
     addition, the investment manager and its affiliates have contractually
     agreed to waive certain fees and to absorb certain expenses until Oct. 31,
     2007, unless sooner terminated at the discretion of the Fund's Board, such
     that net expenses, (excluding fees and expenses of acquired funds), before
     giving effect to any performance incentive adjustment, will not exceed
     1.27% for Class R4. Any amounts waived will not be reimbursed by the Fund.
     These changes were effective Dec. 11, 2006. If these changes had been in
     place for the entire six-month period ended April 30, 2007, the actual and
     hypothetical expenses paid for Class R4 would have been the same as those
     expenses presented in the table above.

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to April 30, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Global Series, Inc. and is registered under
the Investment Company Act of 1940 (as amended) as a diversified, open-end
management investment company. RiverSource Global Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Board. Under normal market conditions, at least 80%
of the Fund's net assets will be invested in equity securities, including
companies located in developed and emerging countries.

The Fund offers Class A, Class B, Class C 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 R4 shares have no sales charge and are offered only to qualifying
   institutional investors.

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

Effective Dec. 11, 2006, the Fund offers additional classes of shares, Class R2,
Class R3 and Class R5, offered to certain institutional investors. These shares
are sold without a front-end sales charge or CDSC. At April 30, 2007, Ameriprise
Financial owned 100% of Class R2, Class R3 and Class R5 shares.

Effective Dec. 1, 2006, the Fund offers an additional class of shares, Class W,
offered through qualifying discretionary accounts. Class W shares are sold
without a front-end sales charge or CDSC. At April 30, 2007, Ameriprise
Financial owned 100% of Class W shares.

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

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

 24 RIVERSOURCE GLOBAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds generally contemplate the use of fair valuation in the
event that price quotations or valuations are not readily available, price
quotations or valuations from other sources are not reflective of market value
and thus deemed unreliable, or a significant event has occurred in relation to a
security or class of securities (such as foreign equities) that is not reflected
in price quotations or valuations from other sources. A fair value price is a
good faith estimate of the value of a security at a given point in time. Many
securities markets and exchanges outside the U.S. close prior to the close of
the New York Stock Exchange and therefore the closing prices for securities in
such markets or on such exchanges may not fully reflect events that occur after
such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, including utilizing a third party pricing service to determine these
fair values. These procedures take into account multiple factors, including
movements in the U.S. securities markets, to determine a good faith estimate
that reasonably reflects the current market conditions as of the close of the
New York Stock Exchange. Short-term securities maturing in more than 60 days
from the valuation date are valued at the market price or approximate market
value based on current interest rates; those maturing in 60 days or less are
valued at amortized cost.

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

                    RIVERSOURCE GLOBAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  25


ILLIQUID SECURITIES

At April 30, 2007, investments in securities included issues that are illiquid
which the Fund currently limits to 10% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at April 30, 2007 was
$11,182,206 representing 1.42% of net assets. These securities may be valued at
fair value according to procedures approved, in good faith, by the Board.
According to board guidelines, certain unregistered securities are determined to
be liquid and are not included within the 10% limitation specified above. Assets
are liquid if they can be sold or disposed of in the ordinary course of business
within seven days at approximately the value at which the asset is valued by the
Fund.

OPTION TRANSACTIONS

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

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

FUTURES TRANSACTIONS

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

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

 26 RIVERSOURCE GLOBAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the statement of operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes. At April 30, 2007, foreign currency holdings consisted of
multiple denominations.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations.

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

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

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value, and requires additional disclosures
about fair-value measurements. The application of SFAS 157 is required for
fiscal years beginning after Nov. 15, 2007 and interim periods within those
fiscal years. The impact of SFAS 157 on the Fund's financial statements is being
evaluated.

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

DIVIDENDS TO SHAREHOLDERS

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

OTHER

Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date or upon receipt of
ex-dividend notification in the case of certain foreign securities. Interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments, LLC
(the Investment Manager) determines which securities will be purchased, held or
sold. The management fee is a percentage of the Fund's average daily net assets
that declines from 0.80% to 0.57% annually as the Fund's assets increase. The
fee may be adjusted upward or downward by a performance incentive adjustment
based on a comparison of the performance of Class A shares of the Fund to the
Lipper Global Funds Index. In certain circumstances, the Board may approve a
change in the index. The maximum adjustment is 0.12% per year. If the
performance difference is less than 0.50%, the adjustment will be zero. The
adjustment decreased the fee by $43,400 for the six months ended April 30, 2007.

The Investment Manager has a Subadvisory Agreement with Threadneedle
International Limited, an indirect wholly-owned subsidiary of Ameriprise
Financial, to subadvise the assets of the Fund.

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

Other expenses in the amount of $3,811 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office expense,
employee compensation, employee health and retirement benefits, and certain
other expenses. Payment of these Fund and Board expenses is facilitated by a
company providing limited administrative services to the Fund and the Board.

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

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

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

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

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
pays the Transfer Agent an annual asset-based fee of 0.05% of the Fund's average
daily net assets attributable to Class R4 shares. Prior to Dec. 11, 2006, the
Fund paid the Transfer Agent an annual account-based fee of $17.50 per
shareholder account.

In addition, the Fund pays the Transfer Agent an annual asset-based fee at a
rate of 0.05% of the Fund's average daily net assets attributable to Class R2,
Class R3 and Class R5 shares 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 closed account fee of $5 per inactive
account, charged on a pro rata basis for 12 months from the date the account
becomes inactive. These fees are included in the transfer agency fees on the
statement of operations.

The Fund has agreements with Ameriprise Financial Services, Inc. and RiverSource
Distributors, Inc. (collectively, the Distributor) for distribution and
shareholder services. Under a Plan and Agreement of Distribution pursuant to
Rule 12b-1, the Fund pays a fee at an annual rate of up to 0.25% of the Fund's
average daily net assets attributable to Class A, 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.

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

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

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

 30 RIVERSOURCE GLOBAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


Sales charges received by the Distributor for distributing Fund shares were
$486,285 for Class A, $26,879 for Class B and $386 for Class C for the six
months ended April 30, 2007.

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

Effective Dec. 11, 2006, with the renaming of Class Y as Class R4, the
Investment Manager and its affiliates have agreed to waive certain fees and
expenses until Oct. 31, 2007, unless sooner terminated at the discretion of the
Board, such that net expenses (excluding fees and expenses of acquired funds),
before giving effect to any performance incentive adjustment, will not exceed
1.27% for Class R4.

During the six months ended April 30, 2007, the Fund's custodian and transfer
agency fees were reduced by $27,115 as a result of earnings and bank fee credits
from overnight cash balances. The Fund also pays custodian fees to Ameriprise
Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $365,572,087 and $400,222,712, respectively, for the six
months ended April 30, 2007. Realized gains and losses are determined on an
identified cost basis.

5. LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend securities
representing up to one-third of the value of its total assets (which includes
collateral for securities on loan) to broker-dealers, banks, or other
institutional borrowers of securities. The Fund receives collateral in the form
of cash and U.S. government securities, equal to at least 100% of the value of
securities loaned, which is marked to the market value of the loaned securities
daily until the securities are returned, e.g., if the value of the securities on
loan increases, additional cash collateral is provided by the borrower. The
Investment Manager serves as securities lending agent for the Fund under the
investment management services agreement pursuant to which the Fund has agreed
to reimburse the Investment Manager for expenses incurred by it in connection
with the lending program, and pursuant to guidelines adopted by and under the
oversight of the Board. At April 30, 2007, securities valued at $29,232,270 were
on loan to brokers. For collateral, the Fund received $30,577,750 in cash. Cash
collateral received is invested in an affiliated money market fund and
short-term securities, including U.S. government securities or other high-grade
debt obligations, which are included in the "Investments in securities." Income
from securities lending amounted to $44,758 for the six months ended April 30,
2007. 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.

6. FORWARD FOREIGN CURRENCY CONTRACTS

At April 30, 2007, the Fund has a forward foreign currency exchange contract
that obligates it to deliver currency at a specified future date. The unrealized
appreciation and/or depreciation on this contract is included in the
accompanying financial statements. See "Summary of significant accounting
policies." The terms of the open contract are as follows:

7. 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.

8. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The Fund must maintain asset coverage for borrowings of at least 300%. The
agreement, which enables the Fund to participate with other RiverSource funds,
permits borrowings up to $500 million, collectively. Interest is charged to each
Fund based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund also
pays a commitment fee equal to its pro rata share of the amount of the credit
facility at a rate of 0.06% per annum. The Fund had no borrowings under the
facility outstanding during the six months ended April 30, 2007.

9. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$468,974,678 at Oct. 31, 2006, that if not offset by capital gains will expire
as follows:

<Table>
<Caption>
    2009           2010          2011
                        
$294,829,842   $143,634,885   $30,509,951
</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.

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.

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

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

 34 RIVERSOURCE GLOBAL EQUITY FUND -- 2007 SEMIANNUAL REPORT


As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and various
Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and
whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. AEFC also agreed to retain an independent
distribution consultant to assist in developing a plan for distribution of all
disgorgement and civil penalties ordered by the SEC in accordance with various
undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

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

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

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

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

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

                    RIVERSOURCE GLOBAL EQUITY FUND -- 2007 SEMIANNUAL REPORT  45


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

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

Investment Performance: For purposes of evaluating the nature, extent and
quality of services provided under the Advisory Agreements, the Board carefully
reviewed the investment performance of the Fund. In this regard, the Board
considered: (i) detailed reports containing data prepared by an independent
organization showing, for various periods, the performance of the Fund, the
performance of a benchmark index, the percentage ranking of the Fund among its
comparison group and the net assets of the Fund; and (ii) a report detailing the
Fund's performance over various periods (including since inception), recent Fund
inflows (and outflows) and a comparison of the Fund's net assets from December
2006 to December 2005. The Board observed that the Fund's investment performance
was appropriate in light of the particular management style and market
conditions involved. Additionally, the Board reviewed the performance of the
Subadviser and the overall "subadvised" strategy. They noted, in particular,
management's ongoing oversight and monitoring of the Subadviser's investment
process and performance.

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

The Board also considered the expected profitability of RiverSource and its
affiliates in connection with RiverSource providing investment management
services to the Fund. In this regard, they referred to a detailed profitability
report, discussing the profitability to RiverSource and Ameriprise Financial
from managing and operating the Fund, including data showing comparative
profitability over the last three years. The Board also considered the services
acquired by the investment manager through the use of commission dollars paid by
the Funds on portfolio transactions. The Board noted that the fees paid by the
Fund should permit the investment manager to offer competitive compensation to
its personnel, make necessary investments in its business and earn an
appropriate profit. The Board concluded that profitability levels were
reasonable.

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

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

 6 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, portfolio manager Nina Hughes discusses the Fund's results and
positioning for the six months ended April 30, 2007.

Q: How did RiverSource Global Technology Fund perform for the semiannual period
   ended April 30, 2007?

A: RiverSource Global Technology Fund's Class A shares increased 7.44%
   (excluding sales charge) for the six months ended April 30, 2007,
   underperforming its benchmark, the unmanaged Goldman Sachs Technology
   Index(R) (GSTI(R)) Composite Index, which increased 8.14% and its peer group,
   represented by the Lipper Science and Technology Funds Index, which increased
   8.28% during the same period.

Q: What factors most significantly affected performance during the fiscal year?

A: The technology sector showed some very positive growth at the end of 2006,
   then experienced some ups and downs in early 2007 before advancing very
   sharply and rapidly in the final month of the semiannual period. During
   periods when technology stocks go up, the market tends to favor funds that
   are the most aggressive and the most similar to the GSTI Composite Index. We
   position the Fund more for the longer term, and the Fund's performance over
   longer periods has supported that approach.

   Most of the Fund's underperformance resulted from stock selection. Individual
   detractors included Spansion, Rackable Systems and XM Satellite Radio
   Holdings. Compared to the GSTI Composite Index, the Fund had a smaller
   position in the strongly performing Microsoft, which hampered results during
   the period.

   Spansion is a mid-cap company that provides memory for cell phones,
   specifically NOR Flash memory. Our analysis of the company, a spin-off from
   Advanced Micro Devices, showed the stock had an extremely good valuation,
   trading at less than book value, and had potential for favorable growth
   dynamics later this year. However, the inventory correction impacting some
   cell phone companies was more significant than we expected. One of Spansion's
   major customers, Motorola, pulled back orders, causing Spansion to miss its
   earnings numbers. We think Spansion will continue to gain market share and
   believe the company is well-positioned for future growth.

                 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  7

QUESTIONS & ANSWERS

   Rackable Systems, another mid-cap company, provides computer network storage
   capacity. The company is a low-cost producer and was gaining share in its
   market, which we thought would offset any downward pricing pressure. However,
   some of the company's larger customers were able to negotiate much lower
   prices than we anticipated, which reduced Rackable Systems' earnings. Even
   though the company was achieving top line growth, its bottom line suffered.
   Once we saw this substantial problem, we exited the stock, avoiding a second
   meaningful decline.

   The Fund had a small position in XM Satellite Radio Holdings. We saw the
   merger with Sirius Satellite Radio as advantageous because a successful
   business model for satellite radio requires a larger number of subscribers.
   Given enough subscribers, we think the growth prospects could be excellent.
   However, we thought this merger would be completed much faster. We reduced
   the Fund's holding of XM Satellite Radio Holdings because it is difficult to
   predict when or if the merger will go through.

   The Fund's position in Microsoft was smaller than that of the GSTI Composite
   Index. We did not consider Microsoft's growth prospects overly compelling.
   Though the Fund benefited from its exposure to Microsoft, the underweight did
   contribute to its underperformance vs. the GSTI Composite Index.

   Positive contributors to the Fund's performance during the six-month period
   included Cogent Communications Group, Nuance Communications and Kronos.
   Cogent Communications Group is an Internet service company that provides
   Internet connectivity for office buildings. Our research showed the company
   had great operating leverage and was a leader in its market. We anticipate
   strong upside growth in its future earnings. Nuance Communications is a
   leader in the speech recognition business, providing software to call
   centers, dictation services and hospitals. Speech technology is becoming
   sophisticated and effective enough that we are seeing reporters and medical
   professionals using it as well as implementation in cars beyond luxury
   models. Nuance Communications has been growing by acquisition, but also
   organically. Kronos provides workforce and resource management software. The
   Fund benefited when Kronos was acquired by a private equity firm late in the
   semiannual period.

 8 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT

QUESTIONS & ANSWERS

Q: What changes did you make to the Fund and how is it currently positioned?

A: We have begun to increase exposure to telecommunications-related stocks, as
   well as semiconductors. We are specifically focusing on companies that
   provide memory for telecommunications and computer devices. There had been
   overcapacity in this area, but we are seeing potential for shortages at the
   end of 2007 and we want the Fund to be well-positioned should that occur.

   THE LARGE AMOUNT OF PRIVATE EQUITY MONEY WAITING TO BE PUT TO WORK SHOULD
   ALSO HELP SUPPORT THE TECHNOLOGY SECTOR AS IT IS A KEY AREA OF FOCUS FOR
   PRIVATE INVESTORS.


   On the telecommunications side there appear to be strong drivers for growth.
   Spending in the telecommunications arena has been weak in the recent past as
   companies were occupied by merger and acquisition activity. Now companies
   that have merged are likely to start spending to attract customers and keep
   the ones they have. In addition, we are seeing the shift from 2G (second
   generation) to 3G (third generation) technology, which should increase
   spending. The Fund's annualized turnover rate during the period was 110%.

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

A: We are positioning the Fund consistent with our outlook for continued
   improvement in the technology sector, while recognizing that companies are
   still working their way through an inventory correction. Technology companies
   in general are better positioned and valuations are very attractive,
   something we have not often seen in the past. The large amount of private
   equity money waiting to be put to work should also help support the
   technology sector as it is a key area of focus for private investors.

   We see excellent growth drivers for technology. For the remainder of 2007, we
   anticipate solid growth in enterprise spending. We also see increased
   spending by telecommunications companies, which should benefit communications
   equipment stocks. Next year, we anticipate a better outlook for personal
   computer-related stocks, which have not performed as well lately.

QUESTIONS & ANSWERS

   We continue to seek companies with extremely compelling risk/reward profiles,
   that appear unattractive to other investors, but which we believe will
   ultimately reward the Fund for investing early.

 10 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE

(UNAUDITED)

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

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended April 30, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads). Therefore, the second line of the table is useful in comparing
ongoing costs only, and will not help you determine the relative total costs of
owning different funds. In addition, if these transactional costs were included,
your costs would have been higher.

</Table>

(a)  Expenses are equal to the Fund's annualized expense ratio as indicated
     above, multiplied by the average account value over the period, multiplied
     by 181/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended April 30, 2007: +7.44%
     for Class A, +7.18% for Class B, +6.67% for Class C, +7.72% for Class I and
     +7.82% for Class R4.
(c)  In September 2006, the Board approved renaming Class Y as Class R4,
     terminating the shareholder servicing agreement, revising the fee structure
     under the transfer agent agreement from an account-based fee to an
     asset-based fee, and adopting a plan administration services agreement. In
     addition, the investment manager and its affiliates have contractually
     agreed to waive certain fees and to absorb certain expenses until Oct. 31,
     2007, unless sooner terminated at the discretion of the Fund's Board, such
     that net expenses, (excluding fees and expenses of acquired funds), before
     giving effect to any performance incentive adjustment, will not exceed
     1.41% for Class R4. Any amounts waived will not be reimbursed by the Fund.
     These changes were effective Dec. 11, 2006. If these changes had been in
     place for the entire six-month period ended April 30, 2007, the actual
     expenses paid for Class R4 would have been $6.96 and the hypothetical
     expenses paid for Class R4 would have been $6.76.

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to April 30, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Global Series, Inc. and is registered under
the Investment Company Act of 1940 (as amended) as a diversified, open-end
management investment company. RiverSource Global Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Board. The Fund invests primarily in equity
securities of companies in the information technology industry throughout the
world.

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

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

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

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

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

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

At April 30, 2007, Ameriprise Financial, Inc. (Ameriprise Financial) 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 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.

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

 20 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT


VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Foreign securities are valued based on quotations from the principal market in
which such securities are normally traded. The procedures adopted by the Board
of Directors of the funds generally contemplate the use of fair valuation in the
event that price quotations or valuations are not readily available, price
quotations or valuations from other sources are not reflective of market value
and thus deemed unreliable, or a significant event has occurred in relation to a
security or class of securities (such as foreign equities) that is not reflected
in price quotations or valuations from other sources. A fair value price is a
good faith estimate of the value of a security at a given point in time. Many
securities markets and exchanges outside the U.S. close prior to the close of
the New York Stock Exchange and therefore the closing prices for securities in
such markets or on such exchanges may not fully reflect events that occur after
such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial will fair value foreign
equity securities pursuant to procedures adopted by the Board of Directors of
the funds, including utilizing a third party pricing service to determine these
fair values. These procedures take into account multiple factors, including
movements in the U.S. securities markets, to determine a good faith estimate
that reasonably reflects the current market conditions as of the close of the
New York Stock Exchange. Short-term securities maturing in more than 60 days
from the valuation date are valued at the market price or approximate market
value based on current interest rates; those maturing in 60 days or less are
valued at amortized cost.

OPTION TRANSACTIONS

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

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

                RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  21


Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund will
realize a gain or loss when the option transaction expires or closes. When an
option is exercised, the proceeds on sales for a written call option, the
purchase cost for a written put option or the cost of a security for a purchased
put or call option is adjusted by the amount of premium received or paid.

FUTURES TRANSACTIONS

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

Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is closed
or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to the
purchase or sale of securities and income and expenses are translated at the
exchange rate on the transaction date. The effect of changes in foreign exchange
rates on realized and unrealized security gains or losses is reflected as a
component of such gains or losses. In the statement of operations, net realized
gains or losses from foreign currency transactions, if any, may arise from sales
of foreign currency, closed forward contracts, exchange gains or losses realized
between the trade date and settlement date on securities transactions, and other
translation gains or losses on dividends, interest income and foreign
withholding taxes. At April 30, 2007, foreign currency holdings were entirely
comprised of Taiwan dollars.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations.

 22 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT


GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

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

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

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board (FASB) released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
(SFAS 157). SFAS 157 establishes an authoritative definition of fair value, sets
out a framework for measuring fair value, and requires additional disclosures
about fair-value measurements. The application of SFAS 157 is required for
fiscal years beginning after Nov. 15, 2007 and interim periods within those
fiscal years. The impact of SFAS 157 on the Fund's financial statements is being
evaluated.

                RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  23


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

DIVIDENDS TO SHAREHOLDERS

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

OTHER

Security transactions are accounted for on the date securities are purchased or
sold. Dividend income is recognized on the ex-dividend date or upon receipt of
ex-dividend notification in the case of certain foreign securities. Interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreements RiverSource Investments, LLC
(the Investment Manager) determines which securities will be purchased, held or
sold. The management fee is a percentage of the Fund's average daily net assets
that declines from 0.72% to 0.595% annually as the Fund's assets increase. The
fee may be adjusted upward or downward by a performance incentive adjustment
based on a comparison of the performance of Class A shares of the Fund to the
Lipper Science and Technology Funds Index. In certain circumstances, the Board
may approve a change in the index. The maximum adjustment is 0.12% per year. If
the performance difference is less than 0.50%, the adjustment will be zero. The
adjustment increased the fee by $100,915 for the six months ended April 30,
2007.

Under an Administrative Services Agreement, the Fund pays Ameriprise Financial a
fee for administration and accounting services at a percentage of the Fund's
average daily net assets that declines from 0.06% to 0.03% annually as the
Fund's assets increase.

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

Other expenses in the amount of $1,056 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office expense,
employee compensation, employee health and retirement benefits, and certain
other expenses. Payment of these Fund and Board expenses is facilitated by a
company providing limited administrative services to the Fund and the Board.

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

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

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

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

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised from
an account-based fee for Class Y to an asset-based fee for Class R4. The Fund
pays the Transfer Agent an annual asset-based fee at a rate of 0.05% of the
Fund's average daily net assets attributable to Class R4 shares. Prior to Dec.
11, 2006, the Fund paid the Transfer Agent an annual account-based fee of $17.50
per shareholder account.

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

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

                RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  25


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

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

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

Sales charges received by the Distributor for distributing Fund shares were
$84,716 for Class A, $14,811 for Class B and $240 for Class C for the six months
ended April 30, 2007.

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

Effective Dec. 11, 2006, with the renaming of Class Y as Class R4, the
Investment Manager and its affiliates have agreed to waive certain fees and
expenses until Oct. 31, 2007, unless sooner terminated at the discretion of the
Board, such that net expenses (excluding fees and expenses of acquired funds)
before giving effect to any performance incentive adjustment, will not exceed
1.41% for Class R4.

During the six months ended April 30, 2007, the Fund's custodian and transfer
agency fees were reduced by $6,622 as a result of earnings and bank fee credits
from overnight cash balances. The Fund also pays custodian fees to Ameriprise
Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $185,331,271 and $197,628,424, respectively, for the six
months ended April 30, 2007. Realized gains and losses are determined on an
identified cost basis.

5. LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend securities
representing up to one-third of the value of its total assets (which includes
collateral for securities on loan) to broker-dealers, banks, or other
institutional borrowers of securities. The Fund receives collateral in the form
of cash and U.S. government securities, equal to at least 100% of the value of
securities loaned, which is marked to the market value of the loaned securities
daily until the securities are returned, e.g., if the value of the securities on
loan increases, additional cash collateral is provided by the borrower. The
Investment Manager serves as securities lending agent for the Fund under the
investment management services agreement pursuant to which the Fund has agreed
to reimburse the Investment Manager for expenses incurred by it in connection
with the lending program, and pursuant to guidelines adopted by and under the
oversight of the Board. At April 30, 2007, securities valued at $6,364,970 were
on loan to brokers. For collateral, the Fund received $6,857,000 in cash. Cash
collateral received is invested in an affiliated money market fund and
short-term securities, including U.S. government securities or other high-grade
debt obligations, which are included in the "Investments in securities." Income
from securities lending amounted to $22,670 for the six months ended April 30,
2007. 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.

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

                RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  27


6. AFFILIATED MONEY MARKET FUND

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

7. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The Fund must maintain asset coverage for borrowings of at least 300%. The
agreement, which enables the Fund to participate with other RiverSource funds,
permits borrowings up to $500 million, collectively. Interest is charged to each
Fund based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund also
pays a commitment fee equal to its pro rata share of the amount of the credit
facility at a rate of 0.06% per annum. The Fund had no borrowings under the
facility outstanding during the six months ended April 30, 2007.

8. CAPITAL LOSS CARRY-OVER

For federal income tax purposes the Fund had a capital loss carry-over of
$362,948,879 at Oct. 31, 2006, that if not offset by capital gains will expire
as follows:

<Table>
<Caption>
    2009          2010
            
$281,649,652   $81,299,227
</Table>

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

9. 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.

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

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

                RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  29


As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and various
Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to pay
disgorgement of $10 million and civil money penalties of $7 million. AEFC also
agreed to make presentations at least annually to its board of directors and the
relevant mutual funds' board that include an overview of policies and procedures
to prevent market timing, material changes to these policies and procedures and
whether disclosures related to market timing are consistent with the SEC order
and federal securities laws. AEFC also agreed to retain an independent
distribution consultant to assist in developing a plan for distribution of all
disgorgement and civil penalties ordered by the SEC in accordance with various
undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review of
its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

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

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

 30 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT


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

                RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  35


APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

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

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

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

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

 36 RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT


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

Investment Performance:  For purposes of evaluating the nature, extent and
quality of services provided under the IMS Agreement, the Board carefully
reviewed the investment performance of the Fund. In this regard, the Board
considered: (i) detailed reports containing data prepared by an independent
organization showing, for various periods, the performance of the Fund, the
performance of a benchmark index, the percentage ranking of the Fund among its
comparison group and the net assets of the Fund; and (ii) a report detailing the
Fund's performance over various periods (including since inception), recent Fund
inflows (and outflows) and a comparison of the Fund's net assets from December
2006 to December 2005. The Board observed that the Fund's investment performance
met expectations.

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

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

                RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2007 SEMIANNUAL REPORT  37


The Board also considered the expected profitability of RiverSource and its
affiliates in connection with RiverSource providing investment management
services to the Fund. In this regard, they referred to a detailed profitability
report, discussing the profitability to RiverSource and Ameriprise Financial
from managing and operating the Fund, including data showing comparative
profitability over the last three years. The Board also considered the services
acquired by the investment manager through the use of commission dollars paid by
the Funds on portfolio transactions. The Board noted that the fees paid by the
Fund should permit the investment manager to offer competitive compensation to
its personnel, make necessary investments in its business and earn an
appropriate profit. The Board concluded that profitability levels were
reasonable.

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

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