For further detail about these holdings, please refer to the section entitled
"Investments in Securities."

Investment products, including shares of mutual funds, involve investment risks
including possible loss of principal and fluctuation in value.

International investing involves increased risk and volatility, not typically
associated with domestic investing, due to changes in currency exchange rates,
foreign government regulations, differences in auditing and accounting
standards, potential political and economic instability, limited liquidity, and
volatile prices. The risks of international investing are particularly
significant in emerging markets.

The Fund primarily invests in large-capitalization companies but may invest a
small portion in small- and mid-capitalization companies. Stocks of small- and
mid-capitalization companies involve substantial risk. Historically, these
stocks have experienced greater price volatility than stocks of larger
companies, and they can be expected to do so in the future.

Fund holdings are subject to change.

QUESTIONS & ANSWERS

                           WITH PORTFOLIO MANAGEMENT

BELOW, RIVERSOURCE EMERGING MARKETS FUND PORTFOLIO MANAGERS JULIAN THOMPSON AND
JULES MORT OF THREADNEEDLE INTERNATIONAL LIMITED (THREADNEEEDLE) DISCUSS THE
FUND'S RESULTS AND POSITIONING FOR THE 12 MONTHS ENDED OCT. 31, 2005.

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 FISCAL YEAR ENDED
     OCT. 31, 2005?

A:   The Fund returned 31.83% (Class A shares excluding sales charge) for the
     12-month period. The Fund's benchmark, the Morgan Stanley Capital
     International (MSCI) Emerging Markets Index (MSCI Index), returned 34.34%
     over the same period. The Fund's peer group, the Lipper Emerging Markets
     Funds Index, returned 32.97% for the year.

Q:   WHAT FACTORS MOST SIGNIFICANTLY AFFECTED PERFORMANCE?

     Asset allocation was the main driver of performance. Latin America was up
     more than 61%, Europe, the Middle East and Africa (EMEA) rose more than 39%
     and Asia was up more than 23% over the course of the 12-month reporting
     period. The Fund consistently held a greater exposure to Latin America than
     did the MSCI Index, and because Latin America clearly outperformed other
     regions, our larger position relative to the MSCI Index's position was a
     very positive contributor to performance. Also throughout the year, we had
     more exposure to EMEA and significantly less exposure to Asia compared to
     the MSCI Index.

     At the country level, our largest position above that of the MSCI Index was
     Mexico, up nearly 53% (in U.S. dollar terms) over the course of the year.
     We also maintained a consistently larger position than did the MSCI Index
     in Brazil, which was up approximately 76%. Outside of the Latin American
     region, we were very positive on Russia throughout the period, which rose
     nearly 39%. Although South Korea performed very well, up more than 46%, the
     Fund had a smaller position there than did the MSCI Index, and having a
     smaller exposure in Korea hurt performance. On the other hand, having
     lesser positions in China, Taiwan and Malaysia than did the MSCI Index
     benefited the Fund. China, Taiwan and Malaysia gained approximately 17%, 4%
     and 8% respectively and proved to be disappointing compared to other
     countries' developing markets over the year.

     Sector weighting impacted performance significantly. By having positions in
     the energy and utilities sectors that were less than the MSCI Index for
     much of the year, performance suffered. Energy and utilities were the best
     performing sectors, with energy up nearly 54% and utilities up more than
     37% over the 12-month period. We missed much of that run up.

5 -- RIVERSOURCE EMERGING MARKETS FUND -- 2005 ANNUAL REPORT

<Page>

QUESTIONS & ANSWERS

- -    THE RESULT OF FALLING INTEREST RATES IS INCREASED ACCESS TO CONSUMER
     CREDIT, WHICH LEADS US TO FOCUS ON CONSUMER-RELATED SECTORS.

     Stock selection also contributed to performance. Among the note-worthy
     individual stocks were Banco Bradesco, a Brazilian bank, rising
     approximately 130% in a year. We added Banco Bradesco in the second half of
     the period and benefited from some of its substantial gains. Cia Vale do
     Rio Doce, a Brazilian iron ore producer, is another long-term holding that
     has done very well this year, rising 70%. On the other hand, some stocks
     were a drag on performance. The worst performing stocks were in Taiwan's
     banking sector. The whole sector has suffered from a deterioration in asset
     quality in unsecured lending. Taishin Financial Holdings and Chinatrust
     Financial Holding both suffered a sharp sell off. We have subsequently
     eliminated exposure to these holdings as we anticipate a protracted period
     of high provisioning expenses. Cathay Financial Holding, an insurance and
     banking business, also delivered undistinguished performance, although we
     continue to maintain a holding here as the insurance business is enjoying
     better business conditions. Check Point Software Technologies, an Israeli
     company, was a long-term holding in the Fund. The company had disappointing
     revenue growth and did not deliver on new product expectations. We sold our
     entire position in Check Point Software Technologies in the second half of
     the period.

<Page>

QUESTIONS & ANSWERS

Q:   WHAT CHANGES DID YOU MAKE TO THE FUND AND HOW IS IT CURRENTLY POSITIONED?

A:   Increasing the Fund's energy weighting was perhaps the most significant
     change. We began the fiscal year with an energy position approximately 5%
     less than that of the MSCI Index. We ended the year with a position greater
     than that index, by 1.5%. As discussed above, being "light" on energy early
     in the year was a drag on performance. Late in the reporting period, we
     changed our expectations regarding the outlook for oil prices, and became
     more positive on energy. We raised our exposure to both the energy sector
     and Asia by buying CNOOC, the Chinese oil company. You may recall that
     CNOOC tried to purchase California-based energy company Unocal, which led
     the stock to sell off to what we considered to be a very attractive level.
     It has subsequently recovered following the failure of its bid.

     In South Africa, we have become increasingly confident that the economic
     recovery underway is structural rather than cyclical. In other words, we
     have become more confident that interest rates are likely to stay low and
     that its currency is not vulnerable in the near term. This has given us
     confidence to invest more in the domestic economy in South Africa. Our
     largest holding in South Africa is ABSA Group, which accounts for
     approximately 30% of the South African mortgage market and was recently
     acquired by U.K. financial giant, Barclays. The acquisition was very
     supportive to ABSA Group's stock, which remains listed.

<Page>

QUESTIONS & ANSWERS

     We took some profits in Latin America and reinvested them elsewhere. Even
     with this reduction, we remain overweight in Latin America relative to the
     MSCI Index. We believe Latin America should continue to benefit from
     falling interest rates in its two major markets, Mexico and Brazil. The
     result of falling interest rates is increased access to consumer credit,
     which leads us to focus on consumer-related sectors. Brazilian department
     store Lojas Renner was among the Fund's greatest contributors to
     performance late in the period.

     We reduced the Fund's position in Asia late in the reporting period. We
     have taken a more cautious stance in some countries and have turned our
     attention to others. For example, in Taiwan, the economic cycle is less
     advantageous and valuations less appealing than in Korea. For this reason,
     we have reduced our exposure to Taiwan, via the banking sector as discussed
     in the answer above.

     South Korea is showing signs of economic recovery in its domestic
     consumption sector. The Korean market is benefiting from cheap valuations
     and a lengthening of domestic investors' time horizons. Companies are
     starting to spend and consumers are also in recovery mode. For these
     reasons, we raised our exposure to the Korean financial sector and added to
     the banking sector via stocks such as Kookmin Bank, which is a key
     beneficiary of improving consumption.

     We have maintained a domestic focus in the Fund for much of the year. We
     have concentrated on those sectors, which benefit from rising consumer
     purchasing power, such as consumer staples and financials, which rose 39%
     and 35%, respectively.

Q:   WHAT IS THE FUND'S TACTICAL VIEW AND STRATEGY FOR THE MONTHS AHEAD?

A:   The Fund's strategy remains largely focused on growth companies. We have
     reduced exposure to more cyclical areas, such as steel, and have little
     exposure to other basic industries, such as chemicals and paper. Rather,
     the Fund is focused on domestic sectors, such as consumer discretionary,
     consumer staples and pharmaceuticals. At the end of the reporting period,
     the Fund is overweight in the energy sector but underweight in materials,
     industrials and telecommunication services relative to the MSCI Index.

QUESTIONS & ANSWERS

     The outlook for emerging markets remains strong. Although emerging markets
     tend to underperform during a U.S. interest-rate tightening cycle, it has
     not been a normal cycle, so far. Moreover, there are signs that domestic
     interest rates have peaked in Latin America and will begin to fall from
     their current high levels. Meanwhile, high commodity prices are likely to
     continue to support oil-producing economies such as Mexico, Russia and
     Brazil. Liquidity also remains strong in Asian markets.

     We are encouraged by a continued high level of liquidity in emerging
     markets despite the slightly stronger dollar since the beginning of the
     year. We are seeing very strong commodity prices, which are unusual with a
     strong dollar. These strong prices reflect the extent of demand in
     commodity-hungry China, while other emerging market countries like Brazil
     and Mexico that are net exporters of commodities, in particular minerals
     and crude oil, benefit from that demand. Stronger commodity prices and
     liquidity factors tend to be very beneficial. Our expectation is that
     emerging markets should continue to attract strong capital flows over the
     next few years.

NOTES TO FINANCIAL STATEMENTS

EMERGING MARKETS PORTFOLIO

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Emerging Markets Portfolio (the Portfolio) is a series of World Trust (the
Trust) and is registered under the Investment Company Act of 1940 (as amended)
as a diversified, open-end management investment company. The Portfolio invests
primarily in equity securities of emerging markets companies. The Declaration of
Trust permits the Trustees to issue non-transferable interests in the Portfolio.

The Portfolio'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. Pursuant to procedures adopted by the
Board of Trustees of the portfolios, Ameriprise Financial, Inc. (Ameriprise
Financial) (formerly American Express Financial Corporation) utilizes Fair Value
Pricing (FVP). FVP determinations are made in good faith in accordance with
these procedures. If a development or event is so significant that there is a
reasonably high degree of certainty that the effect of the development or event
has actually caused the closing price to no longer reflect the actual value, the
closing prices, as determined at the close of the applicable foreign market, may
be adjusted to reflect the fair value of the affected foreign securities as of
the close of the New York Stock Exchange. Significant events include material
movements in the U.S. securities markets prior to the opening of foreign markets
on the following trading day. FVP results in an estimated price that reasonably
reflects the current market conditions in order to value the portfolio holdings
such that shareholder transactions receive a fair net asset value. 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 Portfolio 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
Portfolio 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 Portfolio gives up the opportunity for
profit if the

- --------------------------------------------------------------------------------
19 -- RIVERSOURCE EMERGING MARKETS FUND -- 2005 ANNUAL REPORT

<Page>

market price of the security increases. The risk in writing a put option is that
the Portfolio 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 Portfolio pays
a premium whether or not the option is exercised. The Portfolio 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 Portfolio
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 Portfolio may buy
and sell financial futures contracts traded on any U.S. or foreign exchange. The
Portfolio 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 Portfolio 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 Portfolio 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 Portfolio 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 Oct. 31, 2005, foreign currency holdings consisted of
multiple denominations, primarily Taiwan dollars.

The Portfolio 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 Portfolio and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Portfolio is subject to the credit risk that
the other party will not complete its contract obligations.

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

GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

For federal income tax purposes the Portfolio qualifies as a partnership and
each investor in the Portfolio is treated as the owner of its proportionate
share of the net assets, income, expenses and realized and unrealized gains and
losses of the Portfolio. As a "pass-through" entity, the Portfolio therefore
does not pay any income dividends or capital gain distributions.

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. FEES AND EXPENSES

The Trust, on behalf of the Portfolio, has an Investment Management Services
Agreement with RiverSource Investments, LLC (the Investment Manager) to manage
its portfolio. Prior to Oct. 1, 2005, investment management services were
provided by Ameriprise Financial. Under this agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Portfolio's average daily net assets that declines from
1.10% to 1.00% annually as the Portfolio'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 RiverSource Emerging Markets
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 decreased the fee by $251,371 for the year ended Oct. 31,
2005.

Under the agreement, the Trust also pays taxes, brokerage commissions and
nonadvisory expenses, which include custodian fees, audit and certain legal
fees, fidelity bond premiums, registration fees for units, office expenses,
consultants' fees, compensation of trustees, corporate filing fees, expenses
incurred in connection with lending securities of the Portfolio and any other
expenses properly payable by the Trust or Portfolio and approved by the Board.

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

- --------------------------------------------------------------------------------
21 -- RIVERSOURCE EMERGING MARKETS FUND -- 2005 ANNUAL REPORT

<Page>

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 portfolio.

During the year ended Oct. 31, 2005, the Portfolio's custodian fees were reduced
by $2,460 as a result of earnings credits from overnight cash balances. The
Portfolio also pays custodian fees to Ameriprise Trust Company (formerly
American Express Trust Company), an affiliate of Ameriprise Financial.

According to a Placement Agency Agreement, Ameriprise Financial Services, Inc.
(formerly American Express Financial Advisors Inc.) acts as placement agent of
the Trust's units.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $444,624,623 and $438,119,247, respectively, for the
year ended Oct. 31, 2005. Realized gains and losses are determined on an
identified cost basis.

4. FORWARD FOREIGN CURRENCY CONTRACTS

At Oct. 31, 2005, the Portfolio has a forward foreign currency exchange contract
that obligates it to deliver currency at a specified future date. The unrealized
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:

THE BOARD OF TRUSTEES AND UNITHOLDERS
WORLD TRUST

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities, of Emerging Markets Portfolio (a
series of World Trust) as of October 31, 2005, the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period ended October 31, 2005, and the
financial highlights for each of the years in the five-year period ended October
31, 2005. These financial statements and the financial highlights are the
responsibility of portfolio management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers or by other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Emerging Markets Portfolio as of October 31, 2005, and the results of its
operations, changes in its net assets and the financial highlights for each of
the periods stated in the first paragraph above, in conformity with U.S.
generally accepted accounting principles.

institutional investors. Class I shares have no sales charge and are made
available through a separate prospectus supplement provided to investors
eligible to purchase the shares. At Oct. 31, 2005, Ameriprise Financial and the
RiverSource Portfolio Builder Funds owned 100% of Class I shares, which
represents 4.93% of the Fund's net assets.

All classes of shares have identical voting, dividend and liquidation rights.
The distribution fee, transfer agency fees and service fee (class specific
expenses) 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.

INVESTMENT IN EMERGING MARKETS PORTFOLIO

The Fund invests all of its assets in Emerging Markets Portfolio (the
Portfolio), a series of World Trust (the Trust), an open-end investment company
that has the same objectives as the Fund. The Portfolio invests primarily in
equity securities of emerging markets companies.

The Fund records daily its share of the Portfolio's income, expenses and
realized and unrealized gains and losses. The financial statements of the
Portfolio are included elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

The Fund records its investment in the Portfolio at the value that is equal to
the Fund's proportionate ownership interest in the Portfolio's net assets. The
percentage of the Portfolio owned by the Fund at Oct. 31, 2005 was 99.96%.

The Fund's Board approved the withdrawal of the Fund's assets from the
Portfolio. As of Nov. 8, 2005, the Fund invests directly in and manages its own
portfolio of securities rather than investing in the Portfolio.

All securities held by the Portfolio 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

- --------------------------------------------------------------------------------
27 -- RIVERSOURCE EMERGING MARKETS FUND -- 2005 ANNUAL REPORT

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. Pursuant to procedures adopted by the Board of Trustees of the
portfolios, Ameriprise Financial utilizes Fair Value Pricing (FVP). FVP
determinations are made in good faith in accordance with these procedures. If a
development or event is so significant that there is a reasonably high degree of
certainty that the effect of the development or event has actually caused the
closing price to no longer reflect the actual value, the closing prices, as
determined at the close of the applicable foreign market, may be adjusted to
reflect the fair value of the affected foreign securities as of the close of the
New York Stock Exchange. Significant events include material movements in the
U.S. securities markets prior to the opening of foreign markets on the following
trading day. FVP results in an estimated price that reasonably reflects the
current market conditions in order to value the portfolio holdings such that
shareholder transactions receive a fair net asset value. 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.

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.

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 all sections of the Internal Revenue Code
that apply 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.

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been decreased by $693,791
and accumulated net realized loss has been decreased by $693,791.

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.

2. EXPENSES AND SALES CHARGES

In addition to the expenses allocated from the Portfolio, the Fund accrues its
own expenses as follows:

The Fund has an agreement with Ameriprise Financial to provide administrative
services. Under the current 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. Prior to Oct. 1, 2005, the fee
percentage of the Fund's average daily net assets declined from 0.10% to 0.05%
annually as the Fund's assets increased. A minor portion of additional
administrative service expenses paid by the Fund are consultants' fees and fund
office expenses. Under this agreement, the Fund also pays taxes, audit and
certain legal fees, registration fees for shares, compensation of board members,
corporate filing fees and any other expenses properly payable by the Fund and
approved by the Board.

- --------------------------------------------------------------------------------
29 -- RIVERSOURCE EMERGING MARKETS FUND -- 2005 ANNUAL REPORT

<Page>

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.

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 portfolio.

Under a separate Transfer Agency Agreement, RiverSource Service Corporation
(formerly American Express Client 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

- - Class Y $17.50

The incremental transfer agency fee is the amount charged to the specific
classes for the additional expense above the fee for Class Y.

Class I pays 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.

Beginning May 20, 2005, the Transfer Agent implemented 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. (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 up to 0.25% of the Fund's average daily net assets attributable to
Class A shares and up to 1.00% for Class B and Class C shares.

Under a Shareholder Service Agreement, the Fund pays the Distributor a fee for
service provided to shareholders by financial advisors and other servicing
agents. The fee is calculated at a rate of 0.10% of the Fund's average daily net
assets attributable to Class Y shares.

Sales charges received by the Distributor for distributing Fund shares were
$730,166 for Class A, $68,163 for Class B and $661 for Class C for the year
ended Oct. 31, 2005.

For the year ended Oct. 31, 2005, the Investment Manager and its affiliates
waived certain fund level fees and expenses amounting to $4,107, which had an
insignificant impact on the expense ratios. Beginning Oct. 1, 2005, a new
agreement to waive certain fees and expenses is effective until Oct. 31, 2006,
such that net expenses, before giving effect to any performance incentive
adjustment will not exceed 1.99% for Class A, 2.75% for Class B, 2.75% for Class
C, 1.47% for Class I and 1.82% for Class Y of the Funds average daily net
assets.

During the year ended Oct. 31, 2005, the Fund's transfer agency fees were

4. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The agreement went into effect Sept. 20, 2005. 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 0.07%
per annum. Prior to this agreement, the Fund had a revolving credit agreement
that permitted borrowings up to $500 million with The Bank of New York. The Fund
had no borrowings outstanding during the year ended Oct. 31, 2005.

5. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$898,826 at Oct. 31, 2005, that if not offset by capital gains will expire in
2009. 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.

THE BOARD AND SHAREHOLDERS
AXP GLOBAL SERIES, INC.

We have audited the accompanying statement of assets and liabilities of
RiverSource Emerging Markets Fund (a series of AXP Global Series, Inc.) as of
October 31, 2005, the related statement of operations for the year then ended,
the statements of changes in net assets for each of the years in the two-year
period ended October 31, 2005, and the financial highlights for each of the
years in the five-year period ended October 31, 2005. These financial statements
and the financial highlights are the responsibility of fund management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
RiverSource Emerging Markets Fund as of October 31, 2005, and the results of its
operations, changes in its net assets and the financial highlights for each of
the periods stated in the first paragraph above, in conformity with U.S.
generally accepted accounting principles.

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, including management fees; distribution and service (12b-1) fees; and
other Fund 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.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended Oct. 31, 2005.

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.

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

RiverSource Investments, LLC (RiverSource), a wholly-owned subsidiary of
Ameriprise Financial, Inc. (Ameriprise Financial, formerly American Express
Financial Corporation), serves as the investment manager to the Fund. Under an
investment management services agreement (the IMS Agreement), the investment
manager provides investment advice and other services to the Fund. Throughout
the year, the Fund's Board of Directors (the Board) and the Board's Investment
Review and Contracts Committees monitor these services.

Ameriprise Financial had served as investment manager to the Fund until Sept.
29, 2005. On that date, and pursuant to the consent of the Board, Ameriprise
Financial transferred its rights, title, and interest and its burdens and
obligations under the IMS Agreement to RiverSource, its wholly-owned subsidiary.

Each year, the Board determines whether to continue the IMS Agreement by
evaluating the quality and level of services received and the costs associated
with those services. To assist the Board in making this determination, the
investment manager prepares detailed reports for the Board and its Contracts
Committee in March and April and provides data prepared by independent
organizations. The Board gives considerable weight to the work, deliberations
and conclusions of the Contracts and Investment Review Committees in determining
whether to continue the IMS Agreement.

BACKGROUND

This past year, prior to the Board's annual review process, on Feb. 1, 2005,
American Express Company, the former parent of Ameriprise Financial, announced
its intention to pursue a spin-off of Ameriprise Financial by distributing
shares of the common stock of Ameriprise Financial to shareholders of American
Express Company. Following this announcement, the Board determined to proceed
with its annual review process and, after thorough review of the reports and
data provided, at a meeting held in person on April 14, 2005, the Board,
including all of its independent members, determined that the quality and level
of advisory services provided pursuant to the IMS Agreement were satisfactory
and that fees were fair and reasonable. However, in light of the announced plans
of the spin-off, the Board approved continuation of the IMS Agreement with
Ameriprise Financial for only an interim period ending on the later of (i) the
effective date of the spin-off; or (ii) the approval of a new IMS Agreement with
Ameriprise Financial (or its subsidiary) by the shareholders of the Fund, but in
no event for a period longer than one year.

During the course of the six-month period following the April 2005 meeting, the
Board evaluated whether to approve new investment management services agreements
for each of the funds within the Ameriprise Financial fund complex (together,
the Funds) with post-spin Ameriprise Financial (or RiverSource). Independent
counsel, Schulte Roth & Zabel LLP (Schulte), assisted the Boards in fulfilling
their statutory and other responsibilities associated with the spin-off and the
resulting consideration of new contracts, including the new IMS Agreement. The
Board and its committees were provided with a wealth of written and oral
information in this regard. Furthermore, in connection with the Board's
considerations as to whether post-spin Ameriprise Financial, as an entity
independent from American Express Company, would be capable of continuing to
provide a high quality of services to the Funds,

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

the Board's independent members retained their own financial adviser, Credit
Suisse First Boston LLC (CSFB), to assist them in analyzing the capital adequacy
of post-spin Ameriprise Financial. (The costs of independent counsel and CSFB
and of additional meetings of the Boards were borne by Ameriprise Financial as
part of the commitment of the American Express Company to ensure a complete and
thorough review of the proposed spin-off and its effect on the services provided
by Ameriprise Financial and its subsidiaries.) At a meeting of the Board held on
Sept. 8, 2005, the Board, including all of its independent members, approved,
and recommended that shareholders approve, a proposed new IMS Agreement with
RiverSource (the New IMS Agreement). A meeting of the Fund's shareholders is
expected to be held on Feb. 15, 2006 to consider approval of the New IMS
Agreement. If approved, the New IMS Agreement would take effect shortly after
the shareholder meeting. The following section, "Board Considerations Related to
the New IMS Agreement," provides a detailed discussion of the Board's
considerations and determinations respecting the New IMS Agreement.

BOARD CONSIDERATIONS RELATED TO THE NEW IMS AGREEMENT

In carrying out its legal responsibilities associated with the consideration of
the New IMS Agreement, the Board evaluated the following factors:

NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE
FINANCIAL (AND ITS SUBSIDIARIES)

The Board recognized that only a few months had passed since its April 2005
conclusion that the nature, extent and quality of services provided by
Ameriprise Financial were satisfactory and consistent with those that would be
expected for a fund family of the size of the Funds and its determination to
renew the IMS Agreement for the interim period. However, the Board also
recognized the need to supplement this assessment with an evaluation of whether
the spin-off or other factors would result in changes to the advisory services
being provided under the current IMS Agreement.

The Board focused its evaluation on the following factors potentially impacting
the nature, extent and quality of advisory services to be provided by Ameriprise
Financial: (i) Ameriprise Financial's projected capital structure and capital
adequacy as a stand-alone entity; (ii) its legal and regulatory risks; (iii) its
ability to retain and attract personnel; and (iv) its ability to successfully
re-brand its products and services. Based on extensive presentations and reports
by Ameriprise Financial, CSFB and Schulte, the Board concluded that the proposed
capital structure (which includes certain indemnification commitments made by
American Express Company) should enable RiverSource to continue to provide a
high quality and level of advisory services to the Fund. In making this
determination, the Board took into account representations by management of
Ameriprise Financial that projected capital levels would allow Ameriprise
Financial and RiverSource to meet legal and compliance responsibilities, build
their distribution network, pursue technological upgrades, make capital
commitments necessary to retain and attract key personnel devoted to legal and
compliance responsibilities, portfolio management and distribution, and pursue
smaller asset management acquisitions to help grow the asset management
business. The Board accorded significant weight to CSFB's confirmation as to the
reasonableness of the proposed capital structure. The Board also considered the
fact that there were no expected departures of key personnel involved in the
portfolio management, operations and marketing of the Funds as a result of the
announcement of the spin-off.

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

The Board concluded that, based on all of the materials and information
provided, post-spin Ameriprise Financial (including RiverSource) would be in a
position to continue to provide a high quality and level of advisory services to
the Fund.

INVESTMENT PERFORMANCE

The Board next focused on investment performance. The Board reviewed reports
documenting the Fund's performance over one-, three- and/or five-year periods,
as well as the entire period during which its current portfolio manager has
managed the Fund, and compared to relevant Lipper and market indices. The Board
took into account its determination in April 2005 that investment performance
met expectations.

The Board also considered that it had been receiving monthly performance reports
for the Fund and that there had been no significant deviations from April's
overall performance data.

COST OF SERVICES PROVIDED

The Board evaluated comparative fees and the costs of services under the current
IMS Agreement and the New IMS Agreement, including fees charged by Ameriprise
Financial (including RiverSource and other subsidiaries) to institutional
clients as well as those paid to subadvisers. The Board studied RiverSource's
effort (i.e., its "pricing philosophy") to set substantially all Funds' total
expense ratios at or below the median expense ratio of comparable mutual funds
(as compiled by Lipper). The Board observed that the proposed advisory fee
changes are designed to work in tandem with proposed changes to administrative
services fees. It also noted that RiverSource has agreed to voluntarily impose
expense caps or waivers to achieve this pricing objective whenever the expense
ratio exceeded the median expense ratio by more than three basis points (unless
the higher ratio was due to the impact of the performance fee adjustment or was
due to the added costs associated with having subadvisers manage the Fund). The
Board considered that advisory fees under the New IMS Agreement would stay the
same. The Board also took into account the effect of the proposed performance
incentive adjustment on the advisory fee. In this regard, the Board recalled its
past determinations regarding the appropriateness of (i) the use of the relevant
index for the performance comparison; (ii) the methodology for determining when
the Board may change an index used to calculate the performance incentive
adjustment; (iii) the periods used for averaging the Fund's assets and computing
investment performance; and (iv) the length of the period over which performance
is computed. Furthermore, the Board considered that there was limited
opportunity for the Fund to achieve large-scale growth and thus provide
RiverSource with potential economies of scale.

The Board next considered the expected profitability to Ameriprise Financial and
RiverSource derived from their relationship with the Fund, recalling the April
2005 determination that the profitability level was appropriate. The Board noted
that projected profitability of Ameriprise Financial would allow it to operate
effectively and, at the same time, reinvest in RiverSource and its other asset
management businesses. The Board also considered that the proposed changes in
advisory fees and the mergers of certain other Funds would result in revenue
gains to Ameriprise Financial, but that these increases would not materially
alter profit margins due to expected increases in costs associated with the
spin-off, particularly re-branding and separation. CSFB also reported that
Ameriprise Financial's projected level of return on equity was generally
reasonable in light of the returns on equity of its industry competitors. In
evaluating profitability, the Board also considered the benefits Ameriprise
Financial obtains

- --------------------------------------------------------------------------------
46 -- RIVERSOURCE EMERGING MARKETS FUND -- 2005 ANNUAL REPORT

<Page>

through the use of commission dollars paid on portfolio transactions for the
Fund and from other business relationships that result from managing the Fund.
The Board also considered the fees charged by Ameriprise Financial (and its
subsidiaries) to institutional clients as well as the fees paid to, and charged
by, subadvisers, noting the differences in services provided in each case. In
light of these considerations, the Board concluded that projected profitability
levels were appropriate.

ECONOMIES OF SCALE

The Board also considered the "breakpoints" in fees that would be triggered as
Fund net asset levels grew and the extent to which shareholders would benefit
from such growth. The Board observed that the revised fee schedules under the
proposed New IMS Agreement would continue to provide breakpoints similar to
those in place pursuant to the current IMS Agreement. Accordingly, the Board
concluded that the proposed New IMS Agreement provides adequate opportunity for
shareholders to realize benefits as Fund assets grow.

OTHER CONSIDERATIONS

In addition, the Board accorded weight to the fact that, under the New IMS
Agreement, RiverSource Investments is held to a higher standard of care than
under the current IMS Agreement. The Board also noted Ameriprise Financial's
commitment to a culture that adheres to ethical business practice, assigns
accountability to senior management and seeks to identify conflicts and propose
appropriate action to minimize the risks posed by the conflicts.

Furthermore, the Board recognized that it was not limited to considering
management's proposed New IMS Agreement. In this regard, the Board evaluated the
circumstances under which it would consider the retention of an investment
adviser different from RiverSource Investments. The Board concluded, based on
its consultation with independent counsel, that pursuing the retention of a
different adviser was not necessary, primarily because, in its best judgment,
Ameriprise Financial continues to be basically the same organization (from a
functional and managerial standpoint) as it was prior to the spin-off. The Board
reasoned that shareholders purchased shares of the Fund with an expectation that
the current investment advisory organization would be servicing the Fund.

QUESTIONS & ANSWERS

BELOW, RIVERSOURCE GLOBAL BALANCED FUND'S PORTFOLIO MANAGEMENT TEAM, ALEX LYLE
AND STEPHEN THORNBER OF THREADNEEDLE INTERNATIONAL LIMITED (THREADNEEDLE),
DISCUSS THE FUND'S POSITIONING AND RESULTS FOR FISCAL YEAR 2005. THREADNEEDLE,
AN INDIRECT WHOLLY-OWNED SUBSIDIARY OF AMERIPRISE FINANCIAL, INC., ACTS AS THE
SUBADVISER TO THE FUND. ALEX LYLE MANAGES ASSET ALLOCATION. STEVE THORNBER
MANAGES THE PORTION OF THE FUND ALLOCATED TO EQUITY SECURITIES. NICHOLAS PIFER
OF RIVERSOURCE INVESTMENTS, LLC LEADS THE TEAM THAT MANAGES THE PORTION OF THE
FUND ALLOCATED TO DEBT SECURITIES. SHAREHOLDERS WILL BE ASKED TO APPROVE A
MERGER OF THE FUND INTO RIVERSOURCE BALANCED FUND AT A SHAREHOLDER MEETING ON
FEB. 15, 2006. THIS APPROVAL IS NOT GUARANTEED.

Q:   HOW DID THE FUND PERFORM FOR THE FISCAL YEAR?

A:   RiverSource Global Balanced Fund's Class A shares gained 13.82% (excluding
     sales charge) for the 12 months ended October 31, 2005. This underperformed
     the all-equity MSCI All Country World Index, the Fund's benchmark index,
     which advanced 14.87% for the period. The Fund outperformed the Citigroup
     World Government Bond Index (Citigroup World Index), the Fund's benchmark
     index for the fixed income portion of the Fund, which fell 1.76% for the
     annual period. The Fund outperformed the Lipper Global Flexible Funds
     Index, representing the Fund's peer group, which rose 11.33%.

Q:   WHAT WAS THE ASSET ALLOCATION?

A:   At Oct. 31, 2005, the Fund was composed of 69.1% global equities, 29.9%
     global bonds and 1.0% cash. The equity allocation was split between U.S.
     stocks (41.1%) and foreign stocks (58.9%). Within the bond allocation, the
     largest position was foreign government obligations.

Q:   WHAT FACTORS MOST SIGNIFICANTLY AFFECTED EQUITY PERFORMANCE?

A:   Within the equity portion of the Fund, country allocation and stock
     selection proved most effective during the annual period. Sector allocation
     produced more mixed results.

COUNTRY ALLOCATION

     The Fund's significant allocations to Japan, Asia and Latin America and its
     exposure to the U.S., which was less than the MSCI Index, had a positive
     effect on the Fund's relative results. Each of these international equity
     markets notably outperformed the U.S. equity market for the fiscal year.

     On an individual security basis, Asian property companies, such as Hong
     Kong's New World Development and South Korea's Hyundai Development, and
     Japanese financials, such as recently merged bank Mitsubishi UFJ Financial
     Group and insurance firm T&D Holdings, were among the strongest performers
     for the Fund during the annual period.

QUESTIONS & ANSWERS

>    THE FUND'S SIGNIFICANT ALLOCATIONS TO JAPAN, ASIA AND LATIN AMERICA AND ITS
     MODEST EXPOSURE TO THE U.S. HAD A POSITIVE EFFECT ON THE FUND'S RELATIVE
     RESULTS.

     -- STEPHEN THORNBER

     Within technology, the Fund's modest position in semiconductors and
     hardware and its emphasis on software proved beneficial to relative
     results, with the U.S.' Google and Adobe Systems among the winners in this
     sector.

     In health care, a focus on healthcare equipment and biotechnology firms
     over the large pharmaceuticals benefited the Fund over the annual period,
     as large pharmaceuticals as a group struggled with pricing concerns, patent
     challenges and lackluster growth prospects. Switzerland's Nobel Biocare
     Holding and the U.S.' Amgen and ViroPharma were among the outstanding
     performers within this sector. The one large pharmaceutical position the
     Fund did own, Switzerland's Roche Holding, was a strong performer as well.

     Within energy, we emphasized refiners and small exploration and production
     companies and focused less on the major oil companies, another strategy
     that worked well for the Fund during the fiscal year. Canada's EnCana and
     the U.S.' EOG Resources and Valero Energy performed particularly well.

     Of course, there were disappointments as well. Israeli Internet security
     firm Check Point Software Technologies, U.S. retailer Dillard's, and U.S.
     industrial firm Ingersoll-Rand each detracted from relative results, and we
     sold the Fund's positions in each of these stocks during the fiscal year.
     Fund performance was also hurt by its holdings in U.K. supermarket Tesco

QUESTIONS & ANSWERS

     and U.S. specialty retailer Home Depot. However, we continued to hold these
     stocks, as we continue to believe these companies maintain leadership
     status within their industries.

SECTOR POSITIONING

     From an equity sector perspective, the Fund benefited most from its
     significant exposure to energy. The Fund's below-MSCI Index allocations to
     the lagging consumer discretionary and industrials sectors also helped
     performance compared to the Index. A sizable position in materials helped
     the Fund, particularly during the first half of the fiscal year, though the
     benefit was moderated somewhat by our reduction of this allocation during
     the second half of the period.

     Detracting from the Fund's relative results was significant exposure to
     health care and technology, although, as indicated above, this was
     partially offset by effective stock selection within both of these sectors.
     The Fund's less-than-MSCI Index exposure to the strongly performing
     utilities sector hurt performance as well.

Q:   WHAT FACTORS MOST SIGNIFICANTLY AFFECTED FIXED-INCOME PERFORMANCE?

A:   Returns within the global fixed income markets were weak across the board
     during the fiscal year due primarily to the currency effect of a stronger
     U.S. dollar. On a trade-weighted basis, the U.S. dollar gained 4.6% for the
     12 months ended Oct. 31, 2005. Remember, as the value of the U.S. dollar
     increases, the dollar value of foreign investments typically decreases and
     vice versa. Another factor that contributed to weak global bond markets
     were modest returns generated by the bonds themselves, as interest rates
     rose, particularly in the U.S. On a relative basis to the Citigroup World
     Index, the Fund benefited most from effective country allocation and
     currency positioning. Duration management and yield curve positioning
     helped as well.

QUESTIONS & ANSWERS

>      AS FOR CURRENCY POSITIONING, WE INTEND TO MAINTAIN THE FUND'S MODEST
       POSITION IN THE U.S. DOLLAR AND TO SEEK TO MAKE TACTICAL ALLOCATION
       ADJUSTMENTS AS MARKET CONDITIONS WARRANT.

       -- NICHOLAS PIFER

COUNTRY ALLOCATION

     The Fund continued to hold only limited positions in Japanese bonds and
     U.S. bonds and more substantial exposure to core European bonds. This
     strategy worked well, as the core European government bond market
     outperformed both the Japanese government bond market and U.S. Treasury
     market for the fiscal year in local currency terms.

CURRENCY POSITIONING

     The Fund maintained its significant exposure to the euro and several other
     European currencies as well as to the "dollar bloc" currencies of Canada
     and Australia. The Fund gradually increased its exposure to the U.S. dollar
     from a modest to a more sizable position. The Fund maintained its modest
     exposure to the Japanese yen. For the annual period, the Fund's positioning
     in the "dollar bloc" currencies had a rather neutral effect, but relative
     positioning between the yen and euro helped. So, too, did the Fund's
     increased position in the U.S. dollar, as the U.S. dollar strengthened
     approximately 8.7% versus the euro, 11.9% versus the Japanese yen, 5.3%
     versus the British pound and 2.6% versus the Australian dollar. The major
     exception to this trend was the U.S. dollar's weakening 2.4% versus the
     Canadian dollar.

DURATION MANAGEMENT

     We maintained the Fund's duration, a principal measure of interest rate
     risk, approximately half a year shorter than that of the Citigroup World
     Index throughout the annual period. This stance was based on our view that
     the U.S. economy, in particular, was growing at an above-trend pace and
     thus, that the Federal Reserve Board (the Fed) was likely to continue
     raising the targeted federal funds rate until it is back to more
     historically normal levels. Our view on U.S. monetary policy proved
     correct, with the Fed raising the targeted federal funds rate by 200 basis
     points (2%) during the period. Global bond yields generally declined over
     the first half of the fiscal year, and so our duration management detracted
     during this time. However, for the annual period overall, the Fund's short
     duration positioning helped relative results, adding significant

<Page>

QUESTIONS & ANSWERS

     value in the last few months of the period as global bond yields finally
     moved up rather substantially.

YIELD CURVE POSITIONING

     We maintained a yield curve flattening bias on the U.S. bond market and a
     neutral yield curve positioning bias in most other global bond markets
     through most of the fiscal year. Indeed, the U.S. Treasury yield curve
     flattened dramatically over the annual period, meaning short-term rates
     rose more than long-term rates.

Q:   WHAT CHANGES DID YOU MAKE TO THE FUND?

A:   Within the equity portion of the Fund, we decreased the Fund's exposure to
     Latin America. Following a period of outperformance from this region, we
     took profits in several holdings, believing that valuations had become less
     attractive. We probably made this move a bit early, as Latin American
     equities continued to perform well through the fiscal year. Nevertheless,
     we redeployed those assets primarily into Japan. Having begun to add to the
     Fund's Japanese allocation early in the fiscal year, the Fund participated
     fully when this strategy finally paid off during the last four months or so
     of the fiscal year. The Japanese equity market rallied in response to the
     nation's election result, as Prime Minister Koizumi is expected to push
     through several market-friendly reformist policies.

     Within equity sectors, we increased the Fund's positions in energy,
     shifting away from the major oil companies and toward the refiners and
     smaller exploration and production companies. We also increased the Fund's
     holdings in financials, especially in Japan, Asia, the U.K. and continental
     Europe, as valuations appeared attractive. We also added assets into Asian
     property stocks. We reduced the Fund's positions in technology and
     materials.

     Toward the end of the period, we sought to reduce the Fund's overall risk
     profile and lock in some gains, given the heightened concerns over global
     economic growth, rising interest rates and inflation pressures. For
     example, in October, we reduced the Fund's exposure to energy, while still
     maintaining a significant allocation. Investors had started to price in a
     slowdown in demand as a result of high prices. Indeed, demand figures were
     weaker during the month, even though this may have only been a result of an
     inability to access supplies due to Hurricanes Katrina and Rita-related
     interruptions. By virtue of equity appreciation, the Fund's exposure to
     large-cap stocks, i.e. those stocks that had already been in or that had
     moved into the Top 60 of the MSCI All Country World Index over the annual
     period, increased. For instance, Fund holdings in this Top 60 included
     Mitsubishi UFJ Financial Group, BNP Paribas and Google.

<Page>

QUESTIONS & ANSWERS

     Within the fixed income portion of the Fund, as mentioned, we gradually
     increased exposure to the U.S. dollar. Also, given the recent run of strong
     performance by European government bonds, we took some profits there and
     gradually redeployed those assets into U.S. and Japanese government bonds,
     while still maintaining modest exposure to each of these markets. Finally,
     we removed some of the Fund's U.S. yield curve flattening bias, thereby
     reducing the portfolio's sensitivity to changes in interest rates. We
     maintained the Fund's duration shorter than that of the Citigroup World
     Index.

Q:   HOW DO YOU INTEND TO MANAGE THE FUND IN THE COMING MONTHS?

A:   Overall, we maintain a generally positive outlook for the financial
     markets. Global economic growth remains healthy, though not as robust as in
     2004. We are particularly optimistic for ongoing growth in China and Japan,
     less so for Europe. We intend to keep the Fund's significant exposure to
     equities in the coming months. Equity valuations appear reasonably
     attractive, with narrow differentials between value stocks and growth
     stocks, both across the global markets and within many markets. While we do
     not believe this scenario will last long, it gives us the opportunity to
     compare various sectors and industries across global markets, seeking to
     identify the very best growth-oriented prospects wherever they may be.

     Given this view, we intend to maintain the Fund's significant equity
     exposure to Asia and Japan and its more moderate equity exposure to the
     U.S. and the U.K., although we believe we can continue to find attractive
     stocks in these markets on a select, opportunistic basis. We also intend to
     maintain the Fund's more modest exposure to Latin America for the near
     term, as we believe valuations in the region remain stretched. We continue
     to expect energy prices to remain strong as demand outstrips supply. We
     remain positive regarding the energy sector and will likely increase our
     position when the sector and oil prices stabilize. We also remain concerned
     about the consumer sectors, especially in the U.S., the U.K. and core
     Europe, given the potential impact of rising interest rates and inflation
     pressures on consumer spending, which, for some time now, has been the
     driver of economic growth in these regions.

     Within the fixed income portion of the Fund, we intend to lengthen the
     Fund's duration a bit over the near term given that yields have now risen
     to the point that we believe bonds are closer to fair value. Thus, we
     believe it would be prudent to take some profits, especially on the Fund's
     shorter-term positions.

<Page>

QUESTIONS & ANSWERS

     At the same time, we think that yields will move still higher, with the Fed
     likely to continue raising the targeted federal funds rate into the early
     months of 2006.

     As for currency positioning, we intend to maintain the Fund's modest
     position in the U.S. dollar and to seek to make tactical allocation
     adjustments as market conditions warrant. For the time being, cyclical
     factors affecting the U.S. dollar, such as Fed tightening, appear to be
     winning the tug-of-war with ongoing structural problems, such as burgeoning
     current account and trade deficits. We may well re-evaluate this
     positioning once the Fed completes its tightening cycle, as the structural
     problems of the U.S. dollar may once again come to the fore. Another factor
     that may affect the relative strength or weakness of the U.S. dollar in the
     coming months is the actions of other central banks. Based on its recent
     comments, it currently appears that the European Central Bank may raise its
     interest rates in early 2006. This would be its first interest rate hike in
     more than two years. Also, with Japan's economy improving, the Bank of
     Japan may look to remove some of its monetary policy accommodation sooner
     than later. From a country perspective, we continue to favor European
     bonds. As always, we remain focused on careful security selection, as we
     continue to seek opportunities to capitalize on attractively valued bonds.

NOTES TO FINANCIAL STATEMENTS

RIVERSOURCE GLOBAL BALANCED FUND (FORMERLY AXP THREADNEEDLE GLOBAL BALANCED
FUND)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of AXP Global Series, Inc. and is registered under the
Investment Company Act of 1940 (as amended) as a diversified open-end management
investment company. The Fund invests primarily in equity and debt securities of
issuers throughout the world. AXP 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 offers Class A, Class B, Class C and Class Y 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 Y shares have no sales charge and are offered only to qualifying
   institutional investors.

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

The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by 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. Pursuant to procedures adopted by the
Board of Directors of the funds, Ameriprise Financial, Inc. (Ameriprise
Financial) (formerly American Express Financial Corporation) utilizes Fair Value
Pricing (FVP). FVP determinations are made in good faith in accordance with
these procedures. If a development or event is so significant that there is a
reasonably high degree of certainty that the effect of the development or event
has actually caused the closing price to no longer reflect the actual value, the
closing prices, as determined at the close of the applicable foreign market, may
be adjusted to reflect the fair value of the affected foreign securities as of
the close of the New York Stock Exchange. Significant events include material
movements in the U.S. securities markets prior to the opening of foreign markets
on the following trading day. FVP results in an estimated price that reasonably
reflects the current market conditions in order to value the portfolio holdings
such

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

that shareholder transactions receive a fair net asset value. 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 Oct. 31, 2005, 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 Oct. 31, 2005 was
$46,871 representing 0.04% of net assets. These securities are valued at fair
value according to methods selected 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 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.

<Page>

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 Oct. 31, 2005, foreign currency holdings consisted of
multiple denominations, primarily Canadian dollars and European monetary units.

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 all sections of the Internal Revenue Code
that apply to regulated investment companies and to distribute substantially all
of its taxable income to shareholders. No provision for income or excise taxes
is thus required.

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

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been increased by
$2,105,585 and accumulated net realized loss has been increased by $2,105,585.

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. Prior to Oct. 1, 2005, investment management services were provided by
Ameriprise Financial. The management fee is a percentage of the Fund's average
daily net assets that declines from 0.79% to 0.665% 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 Flexible Funds Index. In certain circumstances,
the Board may approve a change in the index. The maximum adjustment is 0.08% per
year. If the performance difference is less than 0.50%, the adjustment will be
zero. The adjustment increased the fee by $72,116 for the year ended Oct. 31,
2005.

Under the current 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. Prior to Oct. 1, 2005, the fee percentage of the
Fund's average daily net assets declined from 0.06% to 0.035% annually as the
Fund's assets increased. A minor portion of additional administrative service
expenses paid by the Fund are consultants' fees and fund office expenses. Under
this agreement, the Fund also pays taxes, audit and certain legal fees,
registration fees for shares, compensation of board members, corporate filing
fees and any other expenses properly payable by the Fund and approved by the
Board.

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.

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 a separate Transfer Agency Agreement, RiverSource Service Corporation
(formerly American Express Client 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
- - Class Y $17.50

The incremental transfer agency fee is the amount charged to the specific
classes for the additional expense above the fee for Class Y.

Beginning May 20, 2005, the Transfer Agent implemented 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.

- --------------------------------------------------------------------------------
28 -- RIVERSOURCE GLOBAL BALANCED FUND -- 2005 ANNUAL REPORT
<Page>

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

Under a Shareholder Service Agreement, the Fund pays the Distributor a fee for
service provided to shareholders by financial advisors and other servicing
agents. The fee is calculated at a rate of 0.10% of the Fund's average daily net
assets attributable to Class Y shares.

Sales charges received by the Distributor for distributing Fund shares were
$146,294 for Class A, $25,558 for Class B and $563 for Class C for the year
ended Oct. 31, 2005.

During the year ended Oct. 31, 2005, the Fund's custodian and transfer agency
fees were reduced by $12,524 as a result of earnings credits from overnight cash
balances. The Fund also pays custodian fees to Ameriprise Trust Company
(formerly American Express 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 $87,611,644 and $79,163,249, respectively, for the year
ended Oct. 31, 2005. Realized gains and losses are determined on an identified
cost basis.

Income from securities lending amounted to $3,158 for the year ended Oct. 31,
2005. 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. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The agreement went into effect Sept. 20, 2005. 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 0.07%
per annum. Prior to this agreement, the Fund had a revolving credit agreement
that permitted borrowings up to $500 million with The Bank of New York. The Fund
had no borrowings outstanding during the year ended Oct. 31, 2005.

7. SUBSEQUENT EVENT

Shareholders will be asked to approve a merger of RiverSource Global Balanced
Fund into RiverSource Balanced Fund at a shareholder meeting on Feb. 15, 2006.
This approval is not guaranteed.

8. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$33,899,972 at Oct. 31, 2005, that if not offset by capital gains will expire as
follows:

<Table>
<Caption>
               2009                      2010                       2011

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.

THE BOARD AND SHAREHOLDERS
AXP GLOBAL SERIES, INC.

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities, of RiverSource Global Balanced Fund
(a series of the AXP Global Series, Inc.) as of October 31, 2005, the related
statement of operations for the year then ended, the statements of changes in
net assets for each of the years in the two-year period ended October 31, 2005,
and the financial highlights for each of the years in the five-year period ended
October 31, 2005. These financial statements and the financial highlights are
the responsibility of fund management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers or by other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
RiverSource Global Balanced Fund as of October 31, 2005, and the results of its
operations, changes in its net assets and the financial highlights for each of
the periods stated in the first paragraph above, in conformity with U.S.
generally accepted accounting principles.

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, including management fees; distribution and service (12b-1) fees; and
other Fund 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.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended Oct. 31, 2005.

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.

     by 185/365 (to reflect the one-half year period).

     for Class A, +6.61% for Class B, +6.41% for Class C and +7.10% for Class Y.
(c)  Effective Oct. 1, 2005, the Fund's Board of Directors approved a change to

     Ameriprise Financial and the Fund. If the revised fee schedule under the
     Administrative Services Agreement had been in place for the entire
     six-month period ended Oct. 31, 2005, the actual expenses paid would have
     been $8.71 for Class A, $12.67 for Class B, $12.66 for Class C and $7.72
     for Class Y; the hypothetical expenses paid would have been $8.48 for Class

41 -- RIVERSOURCE GLOBAL BALANCED FUND -- 2005 ANNUAL REPORT
<Page>

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

RiverSource Investments, LLC (RiverSource), a wholly-owned subsidiary of
Ameriprise Financial, Inc. (Ameriprise Financial, formerly American Express
Financial Corporation), serves as the investment manager to the Fund. Under an
investment management services agreement (the IMS Agreement), the investment
manager provides investment advice and other services to the Fund. Throughout
the year, the Fund's Board of Directors (the Board) and the Board's Investment
Review and Contracts Committees monitor these services.

Ameriprise Financial had served as investment manager to the Fund until Sept.
29, 2005. On that date, and pursuant to the consent of the Board, Ameriprise
Financial transferred its rights, title, and interest and its burdens and
obligations under the IMS Agreement to RiverSource, its wholly-owned subsidiary.

Each year, the Board determines whether to continue the IMS Agreement by
evaluating the quality and level of services received and the costs associated
with those services. To assist the Board in making this determination, the
investment manager prepares detailed reports for the Board and its Contracts
Committee in March and April and provides data prepared by independent
organizations. The Board gives considerable weight to the work, deliberations
and conclusions of the Contracts and Investment Review Committees in determining
whether to continue the IMS Agreement.

BACKGROUND

This past year, prior to the Board's annual review process, on Feb. 1, 2005,
American Express Company, the former parent of Ameriprise Financial, announced
its intention to pursue a spin-off of Ameriprise Financial by distributing
shares of the common stock of Ameriprise Financial to shareholders of American
Express Company. Following this announcement, the Board determined to proceed
with its annual review process and, after thorough review of the reports and
data provided, at a meeting held in person on April 14, 2005, the Board,
including all of its independent members, determined that the quality and level
of advisory services provided pursuant to the IMS Agreement were satisfactory
and that fees were fair and reasonable. However, in light of the announced plans
of the spin-off, the Board approved continuation of the IMS Agreement with
Ameriprise Financial for only an interim period ending on the later of (i) the
effective date of the spin-off; or (ii) the approval of a new IMS Agreement with
Ameriprise Financial (or its subsidiary) by the shareholders of the Fund, but in
no event for a period longer than one year.

During the course of the six-month period following the April 2005 meeting, the
Board evaluated whether to approve new investment management services agreements
for each of the funds within the Ameriprise Financial fund complex (together,
the Funds) with post-spin Ameriprise Financial (or RiverSource). Independent
counsel, Schulte Roth & Zabel LLP (Schulte), assisted the Boards in fulfilling
their statutory and other responsibilities associated with the spin-off and the
resulting consideration of new contracts, including the new IMS Agreement. The
Board and its committees were provided with a wealth of written and oral
information in this regard. Furthermore, in connection with the Board's
considerations as to whether post-spin Ameriprise Financial, as an entity
independent from American Express Company, would be capable of continuing to
provide a high quality of services to the Funds,

- --------------------------------------------------------------------------------
42 -- RIVERSOURCE GLOBAL BALANCED FUND -- 2005 ANNUAL REPORT
<Page>

the Board's independent members retained their own financial adviser, Credit
Suisse First Boston LLC (CSFB), to assist them in analyzing the capital adequacy
of post-spin Ameriprise Financial. (The costs of independent counsel and CSFB
and of additional meetings of the Boards were borne by Ameriprise Financial as
part of the commitment of the American Express Company to ensure a complete and
thorough review of the proposed spin-off and its effect on the services provided
by Ameriprise Financial and its subsidiaries.) At a meeting of the Board held on
Sept. 8, 2005, the Board, including all of its independent members, approved,
and recommended that shareholders approve, a proposed new IMS Agreement with
RiverSource (the New IMS Agreement). A meeting of the Fund's shareholders is
expected to be held on Feb. 15, 2006 to consider approval of the New IMS
Agreement. If approved, the New IMS Agreement would take effect shortly after
the shareholder meeting. The following section, "Board Considerations Related to
the New IMS Agreement," provides a detailed discussion of the Board's
considerations and determinations respecting the New IMS Agreement.

BOARD CONSIDERATIONS RELATED TO THE NEW IMS AGREEMENT

In carrying out its legal responsibilities associated with the consideration of
the New IMS Agreement, the Board evaluated the following factors:

NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE
FINANCIAL (AND ITS SUBSIDIARIES)

The Board recognized that only a few months had passed since its April 2005
conclusion that the nature, extent and quality of services provided by
Ameriprise Financial were satisfactory and consistent with those that would be
expected for a fund family of the size of the Funds and its determination to
renew the IMS Agreement for the interim period. However, the Board also
recognized the need to supplement this assessment with an evaluation of whether
the spin-off or other factors would result in changes to the advisory services
being provided under the current IMS Agreement.

The Board focused its evaluation on the following factors potentially impacting
the nature, extent and quality of advisory services to be provided by Ameriprise
Financial: (i) Ameriprise Financial's projected capital structure and capital
adequacy as a stand-alone entity; (ii) its legal and regulatory risks; (iii) its
ability to retain and attract personnel; and (iv) its ability to successfully
re-brand its products and services. Based on extensive presentations and reports
by Ameriprise Financial, CSFB and Schulte, the Board concluded that the proposed
capital structure (which includes certain indemnification commitments made by
American Express Company) should enable RiverSource to continue to provide a
high quality and level of advisory services to the Fund. In making this
determination, the Board took into account representations by management of
Ameriprise Financial that projected capital levels would allow Ameriprise
Financial and RiverSource to meet legal and compliance responsibilities, build
their distribution network, pursue technological upgrades, make capital
commitments necessary to retain and attract key personnel devoted to legal and
compliance responsibilities, portfolio management and distribution, and pursue
smaller asset management acquisitions to help grow the asset management
business. The Board accorded significant weight to CSFB's confirmation as to the
reasonableness of the proposed capital structure. The Board also considered the
fact that there were no expected departures of key personnel involved in the
portfolio management, operations and marketing of the Funds as a result of the
announcement of the spin-off.

- --------------------------------------------------------------------------------
43 -- RIVERSOURCE GLOBAL BALANCED FUND -- 2005 ANNUAL REPORT
<Page>

The Board concluded that, based on all of the materials and information
provided, post-spin Ameriprise Financial (including RiverSource) would be in a
position to continue to provide a high quality and level of advisory services to
the Fund.

INVESTMENT PERFORMANCE

The Board next focused on investment performance. The Board reviewed reports
documenting the Fund's performance over one-, three- and/or five-year periods,
as well as the entire period during which its current portfolio manager has
managed the Fund, and compared to relevant Lipper and market indices. The Board
took into account its determination in April 2005 that investment performance
met expectations.

The Board also considered that it had been receiving monthly performance reports
for the Fund and that there had been no significant deviations from April's
overall performance data.

COST OF SERVICES PROVIDED

The Board evaluated comparative fees and the costs of services under the current
IMS Agreement and the New IMS Agreement, including fees charged by Ameriprise
Financial (including RiverSource and other subsidiaries) to institutional
clients as well as those paid to subadvisers. The Board studied RiverSource's
effort (i.e., its "pricing philosophy") to set substantially all Funds' total
expense ratios at or below the median expense ratio of comparable mutual funds
(as compiled by Lipper). The Board observed that the proposed advisory fee
changes are designed to work in tandem with proposed changes to administrative
services fees. It also noted that RiverSource has agreed to voluntarily impose
expense caps or waivers to achieve this pricing objective whenever the expense
ratio exceeded the median expense ratio by more than three basis points (unless
the higher ratio was due to the impact of the performance fee adjustment or was
due to the added costs associated with having subadvisers manage the Fund). The
Board considered that advisory fees under the New IMS Agreement would stay the
same. The Board also took into account the effect of the proposed performance
incentive adjustment on the advisory fee. In this regard, the Board recalled its
past determinations regarding the appropriateness of (i) the use of the relevant
index for the performance comparison; (ii) the methodology for determining when
the Board may change an index used to calculate the performance incentive
adjustment; (iii) the periods used for averaging the Fund's assets and computing
investment performance; and (iv) the length of the period over which performance
is computed. Furthermore, the Board considered that there was limited
opportunity for the Fund to achieve large-scale growth and thus provide
RiverSource with potential economies of scale.

The Board next considered the expected profitability to Ameriprise Financial and
RiverSource derived from their relationship with the Fund, recalling the April
2005 determination that the profitability level was appropriate. The Board noted
that projected profitability of Ameriprise Financial would allow it to operate
effectively and, at the same time, reinvest in RiverSource and its other asset
management businesses. The Board also considered that the proposed changes in
advisory fees and the mergers of certain other Funds would result in revenue
gains to Ameriprise Financial, but that these increases would not materially
alter profit margins due to expected increases in costs associated with the
spin-off, particularly re-branding and separation. CSFB also reported that
Ameriprise Financial's projected level of return on equity was generally
reasonable in light of the returns on equity of its industry competitors. In
evaluating profitability, the Board also considered the benefits Ameriprise
Financial obtains

- --------------------------------------------------------------------------------
44 -- RIVERSOURCE GLOBAL BALANCED FUND -- 2005 ANNUAL REPORT
<Page>

through the use of commission dollars paid on portfolio transactions for the
Fund and from other business relationships that result from managing the Fund.
The Board also considered the fees charged by Ameriprise Financial (and its
subsidiaries) to institutional clients as well as the fees paid to, and charged
by, subadvisers, noting the differences in services provided in each case. In
light of these considerations, the Board concluded that projected profitability
levels were appropriate.

ECONOMIES OF SCALE

The Board also considered the "breakpoints" in fees that would be triggered as
Fund net asset levels grew and the extent to which shareholders would benefit
from such growth. The Board observed that the revised fee schedules under the
proposed New IMS Agreement would continue to provide breakpoints similar to
those in place pursuant to the current IMS Agreement. Accordingly, the Board
concluded that the proposed New IMS Agreement provides adequate opportunity for
shareholders to realize benefits as Fund assets grow.

OTHER CONSIDERATIONS

In addition, the Board accorded weight to the fact that, under the New IMS
Agreement, RiverSource Investments is held to a higher standard of care than
under the current IMS Agreement. The Board also noted Ameriprise Financial's
commitment to a culture that adheres to ethical business practice, assigns
accountability to senior management and seeks to identify conflicts and propose
appropriate action to minimize the risks posed by the conflicts.

Furthermore, the Board recognized that it was not limited to considering
management's proposed New IMS Agreement. In this regard, the Board evaluated the
circumstances under which it would consider the retention of an investment
adviser different from RiverSource Investments. The Board concluded, based on
its consultation with independent counsel, that pursuing the retention of a
different adviser was not necessary, primarily because, in its best judgment,
Ameriprise Financial continues to be basically the same organization (from a
functional and managerial standpoint) as it was prior to the spin-off. The Board
reasoned that shareholders purchased shares of the Fund with an expectation that
the current investment advisory organization would be servicing the Fund.

The Fund's Board has approved a merger of the Fund into RiverSource Balanced
Fund. Completion of the merger is subject to final approval by shareholders of
the Fund. Proxy materials regarding the merger will be distributed to
shareholders in December 2005, and a meeting of shareholders to consider the
merger will be scheduled for February 2006.

Individual security ratings are based on information from Standard & Poor's
Corp. and Moody's Investors Service. If a rating is unavailable, the rating is
determined through an internal analysis, if appropriate. 1.2% of the portfolio
rating above was determined through internal analysis.

Investment products, including shares of mutual funds, involve investment risks
including possible loss of principal and fluctuation in value.

International investing involves increased risk and volatility, not typically
associated with domestic investing, due to changes in currency exchange rates,
foreign government regulations, differences in auditing and accounting
standards, potential political and economic instability, limited liquidity, and
volatile prices. The risks of international investing are particularly
significant in emerging markets.

There are risks associated with fixed income investments, including the impact
of interest rates, credit, and inflation. In general, bond prices rise when
interest rates fall and vice versa. This effect is usually more pronounced for
longer-term securities.

Fund holdings are subject to change.

QUESTIONS & ANSWERS
                  WITH PORTFOLIO MANAGEMENT

Q:   HOW DID RIVERSOURCE GLOBAL BOND FUND PERFORM FOR THE FISCAL YEAR?

A:   RiverSource Global Bond Fund's Class A shares declined -1.18% (excluding
     sales charge) for the 12 months ended Oct. 31, 2005. The Fund
     underperformed its benchmark, the Lehman Brothers Global Aggregate Index
     (Lehman Global Index), which fell -0.72%. The Fund also underperformed the
     Lipper Global Income Funds Index, representing the Fund's peer group, which
     increased 1.16% during the same period.

Q:   WHAT FACTORS MOST SIGNIFICANTLY AFFECTED PERFORMANCE?

A:   Returns across the board were weak during the fiscal year due primarily to
     the currency effect of a stronger U.S. dollar. On a trade-weighted basis,
     the U.S. dollar gained 4.6% for the 12 months ended Oct. 31, 2005. As the
     value of the U.S. dollar increases, the dollar value of foreign investments
     typically decreases and vice versa. Another factor that contributed to weak
     global bond markets were modest returns generated by the bonds themselves,
     as interest rates rose, particularly in the U.S.

     Relative to the Lehman Global Index, the Fund benefited most from effective
     country allocation and duration management. Within countries, the Fund
     continued to hold only limited positions in Japanese bonds and U.S. bonds
     and more substantial exposure to core European bonds. This strategy worked
     well, as the core European government bond market outperformed both the
     Japanese government bond market and U.S. Treasury market for the fiscal
     year in local currency terms. A greater exposure than the Lehman Global
     Index to government bonds in other European government bonds had a neutral
     effect

The Securities and Exchange Commission (SEC) yield is calculated by dividing
anticipated net investment income during a 31-day period by the public offering
price (POP) per share on the last day of the period, and converting the results
to yearly figures. See Average Annual Total Returns on page 4 for additional

<Page>

QUESTIONS & ANSWERS

>      RELATIVE TO THE LEHMAN GLOBAL INDEX, THE FUND BENEFITED MOST FROM
       EFFECTIVE COUNTRY ALLOCATION AND DURATION MANAGEMENT.

     overall. The Fund's allocation to Poland's government bonds helped, as this
     market performed quite well during the 12 months. However, these gains were
     largely offset by the detracting effects of a modest exposure to the
     strongly performing U.K. government bond market and a more sizable position
     in Norway's weaker government bond market.

     We maintained the Fund's duration, a principal measure of interest rate
     risk, shorter than that of the Lehman Global Index throughout the annual
     period. This stance was based on our view that the U.S. economy, in
     particular, was growing at an above-trend pace and thus, that the Federal
     Reserve Board (the Fed) was likely to continue raising the targeted federal
     funds rate. The Fed did indeed raise the targeted federal funds rate by 200
     basis points (2%) during the period. Global bond yields generally declined
     during the first half of the fiscal year, and so our duration management
     detracted during this time. However, overall, the Fund's short duration
     positioning helped results, adding significant value in the last few months
     of the period as global bond yields finally moved up rather substantially.

     The Fund's sector allocation and issue selection helped the Fund's results
     as well. While the Fund's exposure to agencies detracted, this was more
     than offset by its holdings in mortgage-backed securities and corporate
     bonds. Of course, the majority of the Fund's holdings remained in the
     government bond sector.

     The Fund maintained its significant exposure to the euro and several other
     European currencies as well as to the "dollar bloc" currencies of Canada,
     Australia and New Zealand during the annual period. The Fund also
     maintained its modest exposure to the U.S. dollar.

- --------------------------------------------------------------------------------
6 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

QUESTIONS & ANSWERS

>      WE INTEND TO LENGTHEN THE FUND'S DURATION A BIT DURING THE NEAR TERM
       GIVEN THAT YIELDS HAVE NOW RISEN TO THE POINT THAT WE BELIEVE BONDS ARE
       CLOSER TO FAIR VALUE.

     Positioning in the U.S. dollar and the euro detracted, as the U.S. dollar
     strengthened approximately 8.7% vs. the euro. Compared to other currencies,
     the U.S. dollar strengthened approximately 11.9% vs. the yen, 5.3% vs. the
     British pound, 2.6% vs. the Australian dollar, and 0.3% vs. the New Zealand
     dollar. The major exception to this trend was the U.S. dollar's weakening
     2.4% vs. the Canadian dollar.

     The Fund underperformed its Lipper group due primarily to its greater
     currency exposure than many of its peers. The Fund does not hedge its
     foreign currency exposure while some of its peers do hedge foreign currency
     or have varying degrees of exposure to U.S. dollar-based assets. During a
     period such as this when the U.S. dollar strengthened vs. most major
     currencies, it is not surprising that the Fund's performance would lag.
     Remember, a strengthening dollar decreases the value of the Fund's foreign
     currency denominated securities when expressed in U.S. dollar terms.

Q:   WHAT CHANGES DID YOU MAKE TO THE FUND AND HOW IS IT CURRENTLY POSITIONED?

A:   We shortened the Fund's duration somewhat during the annual period, mostly
     in the U.S. portion of the portfolio. We moved the Fund's duration from
     slightly less than half a year shorter than that of the Lehman Global Index
     at the start of the fiscal year to about three-fourths of a year shorter
     than the Lehman Global Index by the end of October 2005.

     We maintained a yield curve flattening bias on the U.S. bond market and a
     neutral yield curve positioning bias in most other global bond markets
     through the first half of the fiscal year. Indeed, the U.S. Treasury yield
     curve flattened dramatically during these months, meaning short-term rates
     rose more than long-term rates. As the annual period progressed, we removed
     some of the Fund's U.S. yield curve flattening bias, thereby reducing the
     portfolio's sensitivity to changes in interest rates.

- --------------------------------------------------------------------------------
7 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

QUESTIONS & ANSWERS

     We made some adjustments in currency exposure and country allocation. We
     decreased further the Fund's already modest allocations to both the U.S.
     dollar and U.S. bonds. We, in turn, added to the Fund's already more
     sizable exposure to both the euro and core European bonds. Within sector
     weightings, we became increasingly conservative as the fiscal year
     progressed. We reduced the Fund's position in both investment grade and
     high-yield corporate bonds based on our valuation analysis and added to its
     allocation to AAA-rated commercial mortgage-backed securities (CMBS) and
     asset-backed securities. We view CMBS as high-quality substitutes for
     corporate bonds. Both CMBS and asset-backed securities, in our view, offer
     attractive yields as well as the kind of defensive characteristics we want
     in the current market environment.

Q:   HOW DO YOU INTEND TO MANAGE THE FUND IN THE COMING MONTHS?

A:   We intend to lengthen the Fund's duration a bit during the near term given
     that yields have now risen to the point that we believe bonds are closer to
     fair value. Thus, we believe it would be prudent to take some profits,
     especially on the Fund's shorter-term positions. At the same time, we think
     that yields will move still higher, with the Fed likely to continue raising
     the targeted federal funds rate into the early months of 2006.

     Within sectors, we intend to maintain modest positions in investment grade
     and high yield corporate bonds and U.S. mortgage-backed securities, given
     that we believe these sectors' valuations are not currently compelling. We
     intend to maintain a more sizable exposure to the more defensive AAA-rated
     CMBS and asset-backed securities for the near term. From a country
     perspective, we continue to favor European bonds.

- --------------------------------------------------------------------------------
8 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

QUESTIONS & ANSWERS

     As for currency positioning, we intend to maintain the Fund's modest
     position in the U.S. dollar and to seek to make tactical allocation
     adjustments as market conditions warrant. Cyclical factors affecting the
     U.S. dollar, such as the Fed tightening rates, appeared to have been
     winning the tug-of-war with ongoing structural problems, such as burgeoning
     current account and trade deficits, over the past fiscal year. However, we
     believe that once the Fed completes its tightening cycle in the foreseeable
     future, the structural problems of the U.S. dollar will once again come to
     the fore. Another factor that may affect the relative strength or weakness
     of the U.S. dollar in the coming months is the actions of other central
     banks. Based on its recent comments, it currently appears that the European
     Central Bank may raise its interest rates in early 2006. This would be its
     first interest rate hike in more than two years. Also, with Japan's economy
     improving, the Bank of Japan may look to remove some of its monetary policy
     accommodation sooner than later.

     As always, we constantly 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.

<Page>

NOTES TO INVESTMENTS IN SECURITIES

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

(b)  Non-income producing. For long-term debt securities, item identified is in
     default as to payment of interest and/or principal.

(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 Oct. 31,
     2005, the value of these securities amounted to $29,647,799 or 5.3% of net
     assets.

(e)  Interest rate varies either based on a predetermined schedule or to reflect
     current market conditions; rate shown is the effective rate on Oct. 31,
     2005.

(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.

(g)  At Oct. 31, 2005, the cost of securities purchased, including interest
     purchased, on a when-issued and/or other forward-commitment basis was
     $4,568,279.

(h)  Negligible market value.

(i)  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 Oct. 31, 2005.

(j)  Identifies issues considered to be illiquid as to their marketability (see
     Note 1 to the financial statements). These securities are valued at fair
     value according to methods selected in good faith by the Fund's Board of
     Directors. Information concerning such security holdings at Oct. 31, 2005,
     is as follows:

NOTES TO FINANCIAL STATEMENTS

WORLD INCOME PORTFOLIO

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

World Income Portfolio (the Portfolio) is a series of World Trust (the Trust)
and is registered under the Investment Company Act of 1940 (as amended) as a
non-diversified, open-end management investment company. The Portfolio invests
primarily in debt obligations of U.S. and foreign issuers. The Declaration of
Trust permits the Trustees to issue non-transferable interests in the Portfolio.

The Portfolio'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. Pursuant to procedures adopted by the
Board of Trustees of the portfolios, Ameriprise Financial, Inc. (Ameriprise
Financial) (formerly American Express Financial Corporation) utilizes Fair Value
Pricing (FVP). FVP determinations are made in good faith in accordance with
these procedures. If a development or event is so significant that there is a
reasonably high degree of certainty that the effect of the development or event
has actually caused the closing price to no longer reflect the actual value, the
closing prices, as determined at the close of the applicable foreign market, may
be adjusted to reflect the fair value of the affected foreign securities as of
the close of the New York Stock Exchange. Significant events include material
movements in the U.S. securities markets prior to the opening of foreign markets
on the following trading day. FVP results in an estimated price that reasonably
reflects the current market conditions in order to value the portfolio holdings
such that shareholder transactions receive a fair net asset value. 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.

- --------------------------------------------------------------------------------
25 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

SECURITIES PURCHASED ON A FORWARD-COMMITMENT BASIS

Delivery and payment for securities that have been purchased by the Portfolio 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 Portfolio's net assets the same as owned securities. The
Portfolio designates cash or liquid securities at least equal to the amount of
its forward-commitments. At Oct. 31, 2005, the Portfolio has entered into
outstanding when-issued securities of $3,613,314 and other forward-commitments
of $954,965.

The Portfolio 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
Portfolio to "roll over" its purchase commitments, the Portfolio 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 Portfolio 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
Portfolio 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 Portfolio gives up the opportunity for
profit if the market price of the security increases. The risk in writing a put
option is that the Portfolio 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 Portfolio pays a premium whether or not the option is exercised. The
Portfolio 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 Portfolio
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 Portfolio may buy
and sell financial futures contracts traded on any U.S. or foreign exchange. The
Portfolio 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 Portfolio 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 Portfolio 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 Portfolio recognizes a realized gain or loss when the
contract is closed or expires.

- --------------------------------------------------------------------------------
26 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

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 Oct. 31, 2005, foreign currency holdings consisted of
multiple denominations, primarily European monetary units.

The Portfolio 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 Portfolio and the resulting
unrealized appreciation or depreciation are determined using foreign currency
exchange rates from an independent pricing service. The Portfolio is subject to
the credit risk that the other party will not complete its contract obligations.

TOTAL RETURN SWAP TRANSACTIONS

The Portfolio may enter into swap agreements to earn the total return on a
specified security or index of fixed income securities. Under the terms of the
swaps, the Portfolio either receives or pays the total return on a reference
security or index applied to a notional principal amount. In return, the
Portfolio 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).

Total return swaps are subject to the risk that the counterparty will default on
its obligation to pay net amounts due to the Portfolio.

GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

For federal income tax purposes the Portfolio qualifies as a partnership and
each investor in the Portfolio is treated as the owner of its proportionate
share of the net assets, income, expenses and realized and unrealized gains and
losses of the Portfolio. As a "pass-through" entity, the Portfolio therefore
does not pay any income dividends or capital gain distributions.

- --------------------------------------------------------------------------------
27 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

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. FEES AND EXPENSES

The Trust, on behalf of the Portfolio, has an Investment Management Services
Agreement with RiverSource Investments, LLC (the Investment Manager) to manage
its portfolio. Prior to Oct. 1, 2005, investment management services were
provided by Ameriprise Financial. Under this agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Portfolio's average daily net assets that declines from
0.77% to 0.67% annually as the Portfolio's assets increase.

Under the agreement, the Trust also pays taxes, brokerage commissions and
nonadvisory expenses, which include custodian fees, audit and certain legal
fees, fidelity bond premiums, registration fees for units, office expenses,
consultants' fees, compensation of trustees, corporate filing fees, expenses
incurred in connection with lending securities of the Portfolio and any other
expenses properly payable by the Trust or Portfolio and approved by the Board.

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

During the year ended Oct. 31, 2005, the Portfolio's custodian fees were reduced
by $1,361 as a result of earnings credits from overnight cash balances. The
Portfolio also pays custodian fees to Ameriprise Trust Company (formerly
American Express Trust Company), an affiliate of Ameriprise Financial.

According to a Placement Agency Agreement, Ameriprise Financial Services, Inc.
(formerly American Express Financial Advisors Inc.) acts as placement agent of
the Trust's units.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $430,425,288 and $401,720,416, respectively, for the
year ended Oct. 31, 2005. Realized gains and losses are determined on an
identified cost basis.

Income from securities lending amounted to $14,624 for the year ended Oct. 31,
2005. The risks to the Portfolio of securities lending are that the borrower may
not provide additional collateral when required or return the securities when
due.

4. FORWARD FOREIGN CURRENCY CONTRACTS

At Oct. 31, 2005, the Portfolio has forward foreign currency exchange contracts
that obligate it to deliver currencies at specified future dates. The unrealized
appreciation and/or depreciation on these contracts is included in the

                                               REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD OF TRUSTEES AND UNITHOLDERS
WORLD TRUST

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities, of World Income Portfolio (a series
of World Trust) as of October 31, 2005, the related statement of operations for
the year then ended, the statements of changes in net assets for each of the
years in the two-year period ended October 31, 2005, and the financial
highlights for each of the years in the five-year period ended October 31, 2005.
These financial statements and the financial highlights are the responsibility
of portfolio management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers or by other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of World
Income Portfolio as of October 31, 2005, and the results of its operations,
changes in its net assets and the financial highlights for each of the periods
stated in the first paragraph above, in conformity with U.S. generally accepted
accounting principles.

NOTES TO FINANCIAL STATEMENTS

RIVERSOURCE GLOBAL BOND FUND (FORMERLY AXP GLOBAL BOND FUND)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of AXP Global Series, Inc. and is registered under the
Investment Company Act of 1940 (as amended) as a non-diversified open-end
management investment company. AXP 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 offers Class A, Class B, Class C and Class Y 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 Y shares have no sales charge and are offered only to qualifying
   institutional investors.

The Fund offers an additional class of shares, Class I, exclusively to certain
institutional investors. Class I shares have no sales charges and are made
available through a separate prospectus supplement provided to investors
eligible to purchase the shares. At Oct. 31, 2005, Ameriprise Financial and the
RiverSource Portfolio Builder Funds owned 100% of Class I shares, which
represents 15.90% of the Fund's net assets.

All classes of shares have identical voting, dividend and liquidation rights.
The distribution fee, transfer agency fees and service fee (class specific
expenses) 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.

INVESTMENT IN WORLD INCOME PORTFOLIO

The Fund invests all of its assets in the World Income Portfolio (the
Portfolio), a series of World Trust, an open-end investment company that has the
same objectives as the Fund. The Portfolio invests primarily in debt obligations
of U.S. and foreign issuers.

The Fund records daily its share of the Portfolio's income, expenses and
realized and unrealized gains and losses. The financial statements of the
Portfolio are included elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

The Fund records its investment in the Portfolio at the value that is equal to
the Fund's proportionate ownership interest in the Portfolio's net assets. The
percentage of the Portfolio owned by the Fund at Oct. 31, 2005 was 99.97%.

The Fund's Board approved the withdrawal of the Fund's assets from the
Portfolio. As of Nov. 8, 2005, the Fund invests directly in and manages its own
portfolio of securities rather than investing in the Portfolio.

- --------------------------------------------------------------------------------
35 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

All securities held by the Portfolio 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. Pursuant
to procedures adopted by the Board of Trustees of the portfolios, Ameriprise
Financial utilizes Fair Value Pricing (FVP). FVP determinations are made in good
faith in accordance with these procedures. If a development or event is so
significant that there is a reasonably high degree of certainty that the effect
of the development or event has actually caused the closing price to no longer
reflect the actual value, the closing prices, as determined at the close of the
applicable foreign market, may be adjusted to reflect the fair value of the
affected foreign securities as of the close of the New York Stock Exchange.
Significant events include material movements in the U.S. securities markets
prior to the opening of foreign markets on the following trading day. FVP
results in an estimated price that reasonably reflects the current market
conditions in order to value the portfolio holdings such that shareholder
transactions receive a fair net asset value. 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.

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.

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 all sections of the Internal Revenue Code
that apply 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.

- --------------------------------------------------------------------------------
36 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been increased by
$12,883,829 and accumulated net realized gain has been decreased by $12,883,829.

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

2. EXPENSES AND SALES CHARGES

In addition to the expenses allocated from the Portfolio, the Fund accrues its
own expenses as follows:

The Fund has an agreement with Ameriprise Financial to provide administrative
services. Under the current 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. Prior to Oct. 1, 2005, the fee
percentage of the Fund's average daily net assets declined from 0.06% to 0.04%
annually as the Fund's assets increased. A minor portion of additional
administrative service expenses paid by the Fund are consultants' fees and fund
office expenses. Under this agreement, the Fund also pays taxes, audit and
certain legal fees, registration fees for shares, compensation of board members,
corporate filing fees and any other expenses properly payable by the Fund and
approved by the Board.

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.

Under a separate Transfer Agency Agreement, RiverSource Service Corporation
(formerly American Express Client 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
- - Class Y $18.50

The incremental transfer agency fee is the amount charged to the specific
classes for the additional expense above the fee for Class Y.

Class I pays 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.

Beginning May 20, 2005, the Transfer Agent implemented 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. (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 up to 0.25% of the Fund's average daily net assets attributable to
Class A shares and up to 1.00% for Class B and Class C shares.

Under a Shareholder Service Agreement, the Fund pays the Distributor a fee for
service provided to shareholders by financial advisors and other servicing
agents. The fee is calculated at a rate of 0.10% of the Fund's average daily net
assets attributable to Class Y shares.

- --------------------------------------------------------------------------------
38 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

Sales charges received by the Distributor for distributing Fund shares were
$619,773 for Class A, $144,502 for Class B and $1,163 for Class C for the year
ended Oct. 31, 2005.

Beginning Oct. 1, 2005, a new agreement to waive certain fees and expenses is
effective until Oct. 31, 2006, such that net expenses will not exceed 1.25% for
Class A, 2.02% for Class B, 2.02% for Class C, 0.95% for Class I and 1.08% for
Class Y. For the year ended Oct. 31, 2005, the Investment Manager and its
affiliates waived certain fees and expenses to 1.35% for Class A, 2.12% for
Class B, 2.12% for Class C, 0.91% for Class I and 1.18% for Class Y. Of these
waived fees and expenses, the transfer agency fees waived for Class A, Class B,
Class C and Class Y were $58,077, $17,961, $700 and $13, respectively, and the
management fees waived at the Fund level were $7,708.

During the year ended Oct. 31, 2005, the Fund's transfer agency fees were
reduced by $16,080 as a result of earnings credits from overnight cash balances.

4. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The agreement went into effect Sept. 20, 2005. 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 0.07%
per annum. Prior to this agreement, the Fund had a revolving credit agreement
that permitted borrowings up to $500 million with The Bank of New York. The Fund
had no borrowings outstanding during the year ended Oct. 31, 2005.

(d)  Total return does not reflect payment of a sales charge.

                                               REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD AND SHAREHOLDERS
AXP GLOBAL SERIES, INC.

We have audited the accompanying statement of assets and liabilities of
RiverSource Global Bond Fund (a series of AXP Global Series, Inc.) as of October
31, 2005, the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years in the two-year period
ended October 31, 2005, and the financial highlights for each of the years in
the five-year period ended October 31, 2005. These financial statements and the
financial highlights are the responsibility of fund management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
RiverSource Global Bond Fund as of October 31, 2005, and the results of its
operations, changes in its net assets and the financial highlights for each of
the periods stated in the first paragraph above, in conformity with U.S.
generally accepted accounting principles.

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, including management fees; distribution and service (12b-1) fees; and
other Fund 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.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended Oct. 31, 2005.

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 185/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended Oct. 31, 2005: -3.98%
     for Class A, -4.40% for Class B, -4.37% for Class C, -3.74% for Class I and
     -3.88% for Class Y.
(c)  Effective Oct. 1, 2005, the Fund's Board of Directors approved a change to
     the fee schedule under the Administrative Services Agreement between
     Ameriprise Financial and the Fund. The Investment Manager and its
     affiliates have contractually agreed to waive certain fees and to absorb
     certain expenses until Oct. 31, 2006, unless sooner terminated at the
     discretion of the Board. Under this expense cap/fee waiver agreement, net
     expenses will not exceed 1.25% for Class A; 2.02% for Class B; 2.02% for
     Class C; 0.95% for Class I; and 1.08% for Class Y. If the revised fee
     schedule under the Administrative Services Agreement and the cap/fee waiver
     agreement had been in place for the entire six-month period ended Oct. 31,
     2005, the actual expenses paid would have been $6.21 for Class A, $10.01
     for Class B, $10.01 for Class C, $4.58 for Class I and $5.37 for Class Y;
     the hypothetical expenses paid would have been $6.40 for Class A, $10.32
     for Class B, $10.32 for Class C, $4.71 for Class I and $5.53 for Class Y.

52 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

RiverSource Investments, LLC (RiverSource), a wholly-owned subsidiary of
Ameriprise Financial, Inc. (Ameriprise Financial, formerly American Express
Financial Corporation), serves as the investment manager to the Fund. Under an
investment management services agreement (the IMS Agreement), the investment
manager provides investment advice and other services to the Fund. Throughout
the year, the Fund's Board of Directors (the Board) and the Board's Investment
Review and Contracts Committees monitor these services.

Ameriprise Financial had served as investment manager to the Fund until Sept.
29, 2005. On that date, and pursuant to the consent of the Board, Ameriprise
Financial transferred its rights, title, and interest and its burdens and
obligations under the IMS Agreement to RiverSource, its wholly-owned subsidiary.

Each year, the Board determines whether to continue the IMS Agreement by
evaluating the quality and level of services received and the costs associated
with those services. To assist the Board in making this determination, the
investment manager prepares detailed reports for the Board and its Contracts
Committee in March and April and provides data prepared by independent
organizations. The Board gives considerable weight to the work, deliberations
and conclusions of the Contracts and Investment Review Committees in determining
whether to continue the IMS Agreement.

BACKGROUND

This past year, prior to the Board's annual review process, on Feb. 1, 2005,
American Express Company, the former parent of Ameriprise Financial, announced
its intention to pursue a spin-off of Ameriprise Financial by distributing
shares of the common stock of Ameriprise Financial to shareholders of American
Express Company. Following this announcement, the Board determined to proceed
with its annual review process and, after thorough review of the reports and
data provided, at a meeting held in person on April 14, 2005, the Board,
including all of its independent members, determined that the quality and level
of advisory services provided pursuant to the IMS Agreement were satisfactory
and that fees were fair and reasonable. However, in light of the announced plans
of the spin-off, the Board approved continuation of the IMS Agreement with
Ameriprise Financial for only an interim period ending on the later of (i) the
effective date of the spin-off; or (ii) the approval of a new IMS Agreement with
Ameriprise Financial (or its subsidiary) by the shareholders of the Fund, but in
no event for a period longer than one year.

During the course of the six-month period following the April 2005 meeting, the
Board evaluated whether to approve new investment management services agreements
for each of the funds within the Ameriprise Financial fund complex (together,
the Funds) with post-spin Ameriprise Financial (or RiverSource). Independent
counsel, Schulte Roth & Zabel LLP (Schulte), assisted the Boards in fulfilling
their statutory and other responsibilities associated with the spin-off and the
resulting consideration of new contracts, including the new IMS Agreement. The
Board and its committees were provided with a wealth of written and oral
information in this regard. Furthermore, in connection with the Board's
considerations as to whether post-spin Ameriprise Financial, as an entity
independent from American Express Company, would be capable of continuing to
provide a high quality of services to the Funds,

- --------------------------------------------------------------------------------
53 -- RIVERSOURCE GLOBAL BOND FUND -- 2005 ANNUAL REPORT
<Page>

the Board's independent members retained their own financial adviser, Credit
Suisse First Boston LLC (CSFB), to assist them in analyzing the capital adequacy
of post-spin Ameriprise Financial. (The costs of independent counsel and CSFB
and of additional meetings of the Boards were borne by Ameriprise Financial as
part of the commitment of the American Express Company to ensure a complete and
thorough review of the proposed spin-off and its effect on the services provided
by Ameriprise Financial and its subsidiaries.) At a meeting of the Board held on
Sept. 8, 2005, the Board, including all of its independent members, approved,
and recommended that shareholders approve, a proposed new IMS Agreement with
RiverSource (the New IMS Agreement). A meeting of the Fund's shareholders is
expected to be held on Feb. 15, 2006 to consider approval of the New IMS
Agreement. If approved, the New IMS Agreement would take effect shortly after
the shareholder meeting. The following section, "Board Considerations Related to
the New IMS Agreement," provides a detailed discussion of the Board's
considerations and determinations respecting the New IMS Agreement.

BOARD CONSIDERATIONS RELATED TO THE NEW IMS AGREEMENT

In carrying out its legal responsibilities associated with the consideration of
the New IMS Agreement, the Board evaluated the following factors:

NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE
FINANCIAL (AND ITS SUBSIDIARIES)

The Board recognized that only a few months had passed since its April 2005
conclusion that the nature, extent and quality of services provided by
Ameriprise Financial were satisfactory and consistent with those that would be
expected for a fund family of the size of the Funds and its determination to
renew the IMS Agreement for the interim period. However, the Board also
recognized the need to supplement this assessment with an evaluation of whether
the spin-off or other factors would result in changes to the advisory services
being provided under the current IMS Agreement.

The Board focused its evaluation on the following factors potentially impacting
the nature, extent and quality of advisory services to be provided by Ameriprise
Financial: (i) Ameriprise Financial's projected capital structure and capital
adequacy as a stand-alone entity; (ii) its legal and regulatory risks; (iii) its
ability to retain and attract personnel; and (iv) its ability to successfully
re-brand its products and services. Based on extensive presentations and reports
by Ameriprise Financial, CSFB and Schulte, the Board concluded that the proposed
capital structure (which includes certain indemnification commitments made by
American Express Company) should enable RiverSource to continue to provide a
high quality and level of advisory services to the Fund. In making this
determination, the Board took into account representations by management of
Ameriprise Financial that projected capital levels would allow Ameriprise
Financial and RiverSource to meet legal and compliance responsibilities, build
their distribution network, pursue technological upgrades, make capital
commitments necessary to retain and attract key personnel devoted to legal and
compliance responsibilities, portfolio management and distribution, and pursue
smaller asset management acquisitions to help grow the asset management
business. The Board accorded significant weight to CSFB's confirmation as to the
reasonableness of the proposed capital structure. The Board also

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

<Page>

considered the fact that there were no expected departures of key personnel
involved in the portfolio management, operations and marketing of the Funds as a
result of the announcement of the spin-off.

The Board concluded that, based on all of the materials and information
provided, post-spin Ameriprise Financial (including RiverSource) would be in a
position to continue to provide a high quality and level of advisory services to
the Fund.

INVESTMENT PERFORMANCE

The Board next focused on investment performance. The Board reviewed reports
documenting the Fund's performance over one-, three- and/or five-year periods,
as well as the entire period during which its current portfolio manager has
managed the Fund, and compared to relevant Lipper and market indices. The Board
took into account its determination in April 2005 that investment performance
met expectations.

The Board also considered that it had been receiving monthly performance reports
for the Fund and that there had been no significant deviations from April's
overall performance data.

COST OF SERVICES PROVIDED

The Board evaluated comparative fees and the costs of services under the current
IMS Agreement and the New IMS Agreement, including fees charged by Ameriprise
Financial (including RiverSource and other subsidiaries) to institutional
clients. The Board studied RiverSource's effort (i.e., its "pricing philosophy")
to set substantially all Funds' total expense ratios at or below the median
expense ratio of comparable mutual funds (as compiled by Lipper). The Board
observed that the proposed advisory fee changes are designed to work in tandem
with proposed changes to administrative services fees. It also noted that
RiverSource has agreed to voluntarily impose expense caps or waivers to achieve
this pricing objective whenever the expense ratio exceeded the median expense
ratio by more than three basis points. The Board considered that advisory fees
under the New IMS Agreement would decrease.

The Board next considered the expected profitability to Ameriprise Financial and
RiverSource derived from their relationship with the Fund, recalling the April
2005 determination that the profitability level was appropriate. The Board noted
that projected profitability of Ameriprise Financial would allow it to operate
effectively and, at the same time, reinvest in RiverSource and its other asset
management businesses. The Board also considered that the proposed changes in
advisory fees and the mergers of certain other Funds would result in revenue
gains to Ameriprise Financial, but that these increases would not materially
alter profit margins due to expected increases in costs associated with the
spin-off, particularly re-branding and separation. CSFB also reported that
Ameriprise Financial's projected level of return on equity was generally
reasonable in light of the returns on equity of its industry competitors. In
evaluating profitability, the Board also considered the benefits Ameriprise
Financial obtains through the use of commission dollars paid on portfolio
transactions for the Fund and from other business relationships that result from
managing the Fund. The Board also considered the fees charged by Ameriprise
Financial (and its subsidiaries) to institutional clients as well as the fees
paid to, and charged by, subadvisers, noting the differences in services
provided in each case. In light of these considerations, the Board concluded
that projected profitability levels were appropriate.

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

<Page>

ECONOMIES OF SCALE

The Board also considered the "breakpoints" in fees that would be triggered as
Fund net asset levels grew and the extent to which shareholders would benefit
from such growth. The Board observed that the revised fee schedules under the
proposed New IMS Agreement would continue to provide breakpoints similar to
those in place pursuant to the current IMS Agreement. Accordingly, the Board
concluded that the proposed New IMS Agreement provides adequate opportunity for
shareholders to realize benefits as Fund assets grow.

OTHER CONSIDERATIONS

In addition, the Board accorded weight to the fact that, under the New IMS
Agreement, RiverSource Investments is held to a higher standard of care than
under the current IMS Agreement. The Board also noted Ameriprise Financial's
commitment to a culture that adheres to ethical business practice, assigns
accountability to senior management and seeks to identify conflicts and propose
appropriate action to minimize the risks posed by the conflicts.

Furthermore, the Board recognized that it was not limited to considering
management's proposed New IMS Agreement. In this regard, the Board evaluated the
circumstances under which it would consider the retention of an investment
adviser different from RiverSource Investments. The Board concluded, based on
its consultation with independent counsel, that pursuing the retention of a
different adviser was not necessary, primarily because, in its best judgment,
Ameriprise Financial continues to be basically the same organization (from a
functional and managerial standpoint) as it was prior to the spin-off. The Board
reasoned that shareholders purchased shares of the Fund with an expectation that
the current investment advisory organization would be servicing the Fund.

For further detail about these holdings, please refer to the section entitled
"Investments in Securities."

Investment products, including shares of mutual funds, involve investment risks
including possible loss of principal and fluctuation in value.

International investing involves increased risk and volatility, not typically
associated with domestic investing, due to changes in currency exchange rates,
foreign government regulations, differences in auditing and accounting
standards, potential political and economic instability, limited liquidity, and
volatile prices. The risks of international investing are particularly
significant in emerging markets.

This Fund primarily invests in large-capitalization companies but may invest a
small portion in small- and mid-capitalization companies. Stocks of small- and
mid-capitalization companies involve substantial risk. Historically, these
stocks have experienced greater price volatility than stocks of larger
companies, and they can be expected to do so in the future.

Fund holdings are subject to change.

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 12 MONTHS ENDED OCT. 31, 2005.
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 FISCAL YEAR ENDED
    OCT. 31, 2005?

A:  The Fund gained 21.48% (Class A shares excluding sales charge) for the
    12-month period ended Oct. 31, 2005. The Fund significantly outperformed its
    benchmark, the Morgan Stanley Capital International (MSCI) All Country World
    Index (MSCI Index), which advanced 14.87% for the period. The Lipper Global
    Funds Index, representing the Fund's peer group, rose 15.12% over the same
    time frame.

Q:  WHAT FACTORS MOST SIGNIFICANTLY AFFECTED PERFORMANCE?

A:  The Fund had an outstanding year. While sector and asset allocation (i.e.,
    geographic) strategies added value over the course of the year, it was stock
    selection that added significant value and drove the Fund's consistent
    outperformance.

    Energy was a strong theme that we followed throughout the period. We kept
    our allocation to the energy sector greater than the MSCI Index throughout
    the year. Some noteworthy energy stocks in the Fund included U.S. oil and
    gas companies Valero Energy and EOG (Enron Oil and Gas) Resources. Both
    companies delivered very strong performance throughout the period. Another
    notable -- and somewhat different type of oil stock -- is Canadian oil sands
    stock EnCana, another strong energy performer. Currently, oil sands account
    for about one-third of Canada's total oil production. Oil sands are composed
    of sand, bitumen (a thick form of crude oil), clay and water. After
    processing, it is sent by pipeline and used by conventional oil refineries.
    Generally, the Fund's positions in energy are geared toward refining,
    marketing and exploration companies at the expense of the larger integrated
    oil companies. This strategy has worked well for the Fund. The majority of
    the Fund's oil and gas holdings are located in North America. Our energy
    holdings with resources in the path of Hurricane Katrina escaped significant
    damage.

    Some notable stocks that helped boost the Fund's performance include U.S.
    companies AmeriTrade and Google Cl A. AmeriTrade, the online brokerage
    company, had some takeover activity that helped the share price. Google Cl
    A, the technology company best known for its internet search engine, did
    extremely well and more than doubled its share price.

QUESTIONS & ANSWERS

>   GENERALLY, THE FUND'S POSITIONS IN ENERGY ARE GEARED TOWARD REFINING,
    MARKETING AND EXPLORATION COMPANIES AT THE EXPENSE OF THE LARGER INTEGRATED
    OIL COMPANIES. THIS STRATEGY HAS WORKED WELL FOR THE FUND.

    Another noteworthy stock is Hyundai Development, a property developer in
    South Korea. It rose more than 100% over the course of the year.

    Although we had reported that stock selection was strong throughout the
    year, the strongest period of outperformance was May through July, or the
    Fund's "third quarter." The list of stock winners in this timeframe was
    extensive, including Canadian oil sand company, EnCana (discussed above), up
    more than 60%; Brazilian iron ore producer Cia Vale do Rio Doce ADR (CVRD),
    up 50% against a backdrop of rising commodity prices; and U.S. biochemical
    company Myogen rose no less than 230%. Myogen researches, develops and
    markets small molecule therapeutics for treating cardiovascular diseases. It
    is a long-term holding that had disappointed for months on end. However, its
    extraordinary performance over this timeframe validated our on-going
    confidence in the company and our patience, which is a necessary virtue when
    investing, but is especially needed in biopharmaceutical company investments
    -- where success is based on innovative research and development, lengthy
    clinical trials and needs in the marketplace.

    During that same three-month timeframe, our strategy in Japan came into its
    own. In retrospect, we focused on Japan too early in the fiscal year. We
    have maintained a larger-than-MSCI Index position since early in the year
    and added to our Japanese positions in early spring. Our position in Japan
    did not start to benefit the Fund until the second half of the fiscal year.
    Then the allocation and sector strategies, as well as stock selection came
    together. Some stocks that contributed significantly to performance were:
    Mitsubishi UFJ Financial Group (MUFG), which is one of the world's largest
    banks; GOLDCREST, a condominium developer; Komatsu, an earth moving
    equipment company that posted very strong profits on the back of burgeoning
    Chinese demand; and Nisshin Steel, a leader for both quality and volume of
    production in the specialty steel industry.

QUESTIONS & ANSWERS

>   OUR POSITION IN JAPAN DID NOT START TO BENEFIT THE FUND UNTIL THE SECOND
    HALF OF THE FISCAL YEAR. THEN THE ALLOCATION AND SECTOR STRATEGIES, AS WELL
    AS STOCK SELECTION CAME TOGETHER.

    Not every strategy or stock played to our favor. The Fund had several
    detractors from performance during the period. One such detractor was our
    underweight position (relative to the MSCI Index) in the industrials sector.
    Industrials did well throughout the year, and we did not fully capture the
    performance in that sector. Another detractor was our too-early entry to the
    Japanese market, as discussed above. Although this asset allocation decision
    later benefited the Fund, we waited nearly six months for the strategy to
    show success. Although we noted that stock selection was beneficial to
    performance throughout the year, not every stock over the annual period was
    a winner. For example, over a three-month period, U.S. orthopaedic mattress
    company Temper-Pedic's stock dropped by 50%. We weathered its first large
    drop because we still held out hope of recovery. However when Temper-Pedic's
    stock fell again, we sold our position. Other disappointing stocks included
    U.S. companies Harley Davidson, the motorcycle manufacturer and Rockwell
    Automation, manufacturer of computer equipment for use in factory automation
    applications.

Q:  WHAT CHANGES DID YOU MAKE TO THE FUND?

A:  Energy was a key contributor to the Fund's performance through much of the
    year, and there was considerable activity in the sector. Spring was an
    especially volatile season for oil stocks. In March, we reduced our
    positions in oil companies. Shortly after, in April, prices on those stocks
    dropped. In May, we re-established our position in oil stocks.

    So, taking profits from holdings, exercising watchful patience and then
    buying on market lows has been a successful strategy that helped boost
    performance. In early October -- late in the fiscal year -- we again reduced
    our oil stocks.

    In the financials sector, we increased our exposure around the world over
    the course of the year. We noted previously that we added MUFG in Japan, but
    also added banks, insurance companies and

- --------------------------------------------------------------------------------
                       RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT -- 7
<Page>

QUESTIONS & ANSWERS

    brokerage service companies in the U.K. and U.S. bank stocks in the U.S.
    have been inexpensive for some time. We believe this will change, so we
    established positions in several large U.S. banks while their valuations
    remained low. We added Bank of America, Wells Fargo & Co., Wachovia and US
    Bancorp to the Fund.

    Another sector-related change was to increase the Fund's health care
    exposure. Companies such as Nobel Biocare Holding, a Swiss company that
    produces innovative orthodontics; St. Jude Medical, a U.S. medical equipment
    and supply company; and German health care services provider Fresenius
    Medical Care have all contributed to performance this year. In the
    biopharmaceutical area, we have had considerable success with U.S. companies
    Myogen (discussed above), Amgen, a developer and producer of innovative
    human therapeutics, and recently added ViroPharma, a company developing
    proprietary antiviral pharmaceuticals for treating viral diseases, such as
    colds and influenza.

    Also, in this period, we have entered a new area of focus in the U.S., home
    building-related companies. One such company that we added to the Fund is
    Home Depot, a specialty retailer for the building trade and home improvement
    do-it-yourself consumers. Many companies related to home construction and
    remodeling in the United States have had a recent setback. We, however, take
    their setback as an encouraging investment opportunity.

    On the asset allocation front, as discussed, we increased our position in
    Japan at certain points throughout the period. Also, in Asia, we reduced our
    position in Hong Kong and later added to our South Korean holdings. Early in
    the period, for example, Hong Kong and South Korea were approximately 6% and
    2% of the Fund. Late in the period, those percentages were reversed with
    South Korea at nearly 4.8%. At the end of the reporting period, the
    countries with the three greatest percentages of the portfolio's assets were
    the U.S. at 37.4%, Japan at 20.0% and the U.K. at 6.4%.

Q:  HOW IS THE FUND CURRENTLY POSITIONED, AND HOW DO YOU INTEND TO MANAGE THE
    FUND IN THE COMING MONTHS?

A:  We believe that our big themes this year -- oil and Japan -- have exhausted
    themselves in the short term. This is not to say that we will desert them,
    but we have cut back on our positions somewhat; here is why:

    -   Oil has had a long, successful run, although fraught with volatility. We
        believe this sector will continue to benefit investors over the long
        term,

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

QUESTIONS & ANSWERS

        but in the short term, oil stocks have slowed. We have reduced the
        Fund's position in oil, but still remain overweight in the energy sector
        relative to the MSCI Index.

    -   Japan has been a key focus over the course of the year, and started to
        pay off in the second half. Even though we have reduced our allocation
        to Japan, we remain heavily invested there. At the end of the period,
        Japan was the Fund's second largest country position. Political and
        economic news late in the year add credence to our optimistic view of
        Japan. In September 2005, Prime Minister Koizumi's decisive victory in
        Japan's general election spurred the Japanese market to new four-year
        highs, fuelled by foreign buying. The election result has enhanced the
        prospects for further reforms in Japan. The brighter economic outlook
        and increasing corporate profitability there have also continued to
        drive the market higher. Also, there has been a notable fall in
        unemployment and an improvement in consumer spending; both bode well for
        the recovering economy. We are bullish on Japan and will likely remain
        so, but we felt a reduction in exposure was necessary at this time.

        Always mindful that markets are volatile, we strive to limit risk, so we
        have reduced our exposure to oil and Japan, although our positions still
        remain above those of the MSCI Index.

        In the near term, we will likely not change the overall structure of the
        Fund much more. Our asset allocation, with its heavy focus on the U.S.,
        is poised for results. We have built up our exposure to South Korea,
        which at the end of the fiscal year was at 4.8%. We see promise here and
        will continue to look for opportunities going forward. On the sector
        side, we have increased our positions in the financials sector, to bring
        it to be the largest sector in the Fund. We anticipate that the addition
        of several U.S., U.K and Japanese banks, brokerage companies and
        insurance companies will benefit the Fund's on-going performance.

        We watch for, as always, sectors with improving returns on capital, some
        growth, and areas that are uncorrelated with other sectors or regions.
        So, by adding new ideas to the Fund, we build in some additional
        diversification and increase the likelihood that the Fund will benefit
        from these new ideas over both the short- and long-term.

NOTES TO FINANCIAL STATEMENTS

WORLD GROWTH PORTFOLIO

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

World Growth Portfolio (the Portfolio) is a series of World Trust (the Trust)
and is registered under the Investment Company Act of 1940 (as amended) as a
diversified, open-end management investment company. The Portfolio invests
primarily in equity securities of companies around the world, including
companies located in developed and emerging countries. The Declaration of Trust
permits the Trustees to issue non-transferable interests in the Portfolio.

The Portfolio'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. Pursuant to procedures adopted by the
Board of Trustees of the portfolios, Ameriprise Financial, Inc. (Ameriprise
Financial) (formerly American Express Financial Corporation) utilizes Fair Value
Pricing (FVP). FVP determinations are made in good faith in accordance with
these procedures. If a development or event is so significant that there is a
reasonably high degree of certainty that the effect of the development or event
has actually caused the closing price to no longer reflect the actual value, the
closing prices, as determined at the close of the applicable foreign market, may
be adjusted to reflect the fair value of the affected foreign securities as of
the close of the New York Stock Exchange. Significant events include material
movements in the U.S. securities markets prior to the opening of foreign markets
on the following trading day. FVP results in an estimated price that reasonably
reflects the current market conditions in order to value the portfolio holdings
such that shareholder transactions receive a fair net asset value. 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.

- --------------------------------------------------------------------------------
20 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

OPTION TRANSACTIONS

To produce incremental earnings, protect gains and facilitate buying and selling
of securities for investments, the Portfolio 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
Portfolio 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 Portfolio gives up the opportunity for
profit if the market price of the security increases. The risk in writing a put
option is that the Portfolio 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 Portfolio pays a premium whether or not the option is exercised. The
Portfolio 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 Portfolio
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 Portfolio may buy
and sell financial futures contracts traded on any U.S. or foreign exchange. The
Portfolio 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 Portfolio 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 Portfolio 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 Portfolio 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 Oct. 31, 2005, foreign currency holdings consisted of
multiple denominations, primarily Taiwan dollars.

- --------------------------------------------------------------------------------
21 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

The Portfolio 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 Portfolio and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Portfolio is subject to the credit risk that
the other party will not complete its contract obligations.

GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

For federal income tax purposes the Portfolio qualifies as a partnership and
each investor in the Portfolio is treated as the owner of its proportionate
share of the net assets, income, expenses and realized and unrealized gains and
losses of the Portfolio. As a "pass-through" entity, the Portfolio therefore
does not pay any income dividends or capital gain distributions.

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. FEES AND EXPENSES

The Trust, on behalf of the Portfolio, has an Investment Management Services
Agreement with RiverSource Investments, LLC (the Investment Manager) to manage
its portfolio. Prior to Oct. 1, 2005, investment management services were
provided by Ameriprise Financial. Under this agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Portfolio's average daily net assets that declines from
0.8% to 0.675% annually as the Portfolio'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 RiverSource Global Equity
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 increased the fee by $417,773 for the year ended Oct. 31, 2005.

Under the agreement, the Trust also pays taxes, brokerage commissions and
nonadvisory expenses, which include custodian fees, audit and certain legal
fees, fidelity bond premiums, registration fees for units, office expenses,
consultants' fees, compensation of trustees, corporate filing fees, expenses
incurred in connection with lending securities of the Portfolio and any other
expenses properly payable by the Trust or Portfolio and approved by the Board.

- --------------------------------------------------------------------------------
22 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

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

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 portfolio.

During the year ended Oct. 31, 2005, the Portfolio's custodian fees were reduced
by $3,574 as a result of earnings credits from overnight cash balances. The
Portfolio also pays custodian fees to Ameriprise Trust Company (formerly
American Express Trust Company), an affiliate of Ameriprise Financial.

According to a Placement Agency Agreement, Ameriprise Financial Services, Inc.
(formerly American Express Financial Advisors Inc.) acts as placement agent of
the Trust's units.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $468,876,014 and $490,183,946, respectively, for the
year ended Oct. 31, 2005. Realized gains and losses are determined on an
identified cost basis.

4. LENDING OF PORTFOLIO SECURITIES

At Oct. 31, 2005, securities valued at $6,438,448 were on loan to brokers. For
collateral, the Portfolio received $7,082,800 in cash. Cash collateral received
is invested in short-term securities, which are included in the short-term
section of the "Investments in securities." Income from securities lending
amounted to $185,022 for the year ended Oct. 31, 2005. The risks to the
Portfolio of securities lending are that the borrower may not provide additional
collateral when required or return the securities when due.

5. FINANCIAL HIGHLIGHTS

The table below shows certain important financial information for evaluating the
Portfolio's results.

THE BOARD OF TRUSTEES AND UNITHOLDERS
WORLD TRUST

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities, of World Growth Portfolio (a series
of World Trust) as of October 31, 2005, the related statement of operations for
the year then ended, the statements of changes in net assets for each of the
years in the two-year period ended October 31, 2005, and the financial
highlights for each of the years in the five-year period ended October 31, 2005.
These financial statements and the financial highlights are the responsibility
of portfolio management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers or by other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of World
Growth Portfolio as of October 31, 2005, and the results of its operations,
changes in its net assets and the financial highlights for each of the periods
stated in the first paragraph above, in conformity with U.S. generally accepted
accounting principles.

NOTES TO FINANCIAL STATEMENTS

RIVERSOURCE GLOBAL EQUITY FUND (FORMERLY AXP THREADNEEDLE GLOBAL EQUITY FUND)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of AXP Global Series, Inc. and is registered under the
Investment Company Act of 1940 (as amended) as a diversified, open-end
management investment company. AXP 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 offers Class A, Class B, Class C and Class Y 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 Y shares have no sales charge and are offered only to qualifying
     institutional investors.

All classes of shares have identical voting, dividend and liquidation rights.
The distribution fee, transfer agency fees and service fee (class specific
expenses) 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.

INVESTMENT IN WORLD GROWTH PORTFOLIO

The Fund invests all of its assets in World Growth Portfolio (the Portfolio), a
series of World Trust (the Trust), an open-end investment company that has the
same objectives as the Fund. The Portfolio invests primarily in equity
securities of companies around the world that are positioned to meet market
needs in a changing world economy.

The Fund records daily its share of the Portfolio's income, expenses and
realized and unrealized gains and losses. The financial statements of the
Portfolio are included elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

The Fund records its investment in the Portfolio at the value that is equal to
the Fund's proportionate ownership interest in the Portfolio's net assets. The
percentage of the Portfolio owned by the Fund at Oct. 31, 2005 was 99.99%.

The Fund's Board approved the withdrawal of the Fund's assets from the
Portfolio. As of Nov. 8, 2005, the Fund invests directly in and manages its own
portfolio of securities rather than investing in the Portfolio.

- --------------------------------------------------------------------------------
28 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

All securities held by the Portfolio 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. Pursuant
to procedures adopted by the Board of Trustees of the portfolios, Ameriprise
Financial utilizes Fair Value Pricing (FVP). FVP determinations are made in good
faith in accordance with these procedures. If a development or event is so
significant that there is a reasonably high degree of certainty that the effect
of the development or event has actually caused the closing price to no longer
reflect the actual value, the closing prices, as determined at the close of the
applicable foreign market, may be adjusted to reflect the fair value of the
affected foreign securities as of the close of the New York Stock Exchange.
Significant events include material movements in the U.S. securities markets
prior to the opening of foreign markets on the following trading day. FVP
results in an estimated price that reasonably reflects the current market
conditions in order to value the portfolio holdings such that shareholder
transactions receive a fair net asset value. 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.

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.

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 all sections of the Internal Revenue Code
that apply 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.

- --------------------------------------------------------------------------------
29 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been increased by $239,162
and accumulated net realized loss has been increased by $239,162.

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

</Table>

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.

2. EXPENSES AND SALES CHARGES

In addition to the expenses allocated from the Portfolio, the Fund accrues its
own expenses as follows:

The Fund has an agreement with Ameriprise Financial to provide administrative
services. Under the current 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. Prior to Oct. 1, 2005, the fee
percentage of the Fund's average daily net assets declined from 0.06% to 0.035%
annually as the Fund's assets increased. A minor portion of additional
administrative service expenses paid by the Fund are consultants' fees and fund
office expenses. Under this agreement, the Fund also pays taxes, audit and
certain legal fees, registration fees for shares, compensation of board members,
corporate filing fees and any other expenses properly payable by the Fund and
approved by the Board.

- --------------------------------------------------------------------------------
30 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

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.

Under a separate Transfer Agency Agreement, RiverSource Service Corporation
(formerly American Express Client 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
- - Class Y $17.50

The incremental transfer agency fee is the amount charged to the specific
classes for the additional expense above the fee for Class Y.

Beginning May 20, 2005, the Transfer Agent implemented 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. (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 up to 0.25% of the Fund's average daily net assets attributable to
Class A shares and up to 1.00% for Class B and Class C shares.

Under a Shareholder Service Agreement, the Fund pays the Distributor a fee for
service provided to shareholders by financial advisors and other servicing
agents. The fee is calculated at a rate of 0.10% of the Fund's average daily net
assets attributable to Class Y shares.

Sales charges received by the Distributor for distributing Fund shares were
$689,672 for Class A, $87,985 for Class B and $405 for Class C for the year
ended Oct. 31, 2005.

During the year ended Oct. 31, 2005, the Fund's transfer agency fees were
reduced by $21,787 as a result of earnings credits from overnight cash balances.

</Table>

4. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The agreement went into effect Sept. 20, 2005. 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 0.07%
per annum. Prior to this agreement, the Fund had a revolving credit agreement
that permitted borrowings up to $500 million with The Bank of New York. The Fund
had no borrowings outstanding during the year ended Oct. 31, 2005.

5. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$565,449,466 at Oct. 31, 2005, that if not offset by capital gains will expire
as follows:

<Table>
<Caption>
                       2009                 2010                2011
                                                       
                   $391,304,630         $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.

THE BOARD AND SHAREHOLDERS
AXP GLOBAL SERIES, INC.

We have audited the accompanying statement of assets and liabilities of
RiverSource Global Equity Fund (a series of AXP Global Series, Inc.) as of
October 31, 2005, the related statement of operations for the year then ended,
the statements of changes in net assets for each of the years in the two-year
period ended October 31, 2005, and the financial highlights for each of the
years in the five-year period ended October 31, 2005. These financial statements
and the financial highlights are the responsibility of fund management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
RiverSource Global Equity Fund as of October 31, 2005, and the results of its
operations, changes in its net assets and the financial highlights for each of
the periods stated in the first paragraph above, in conformity with U.S.
generally accepted accounting principles.

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, including management fees; distribution and service (12b-1) fees; and
other Fund 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.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended Oct. 31, 2005.

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.

     Ameriprise Financial and the Fund. If the revised fee schedule under the
     Administrative Services Agreement had been in place for the entire

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

RiverSource Investments, LLC (RiverSource), a wholly-owned subsidiary of
Ameriprise Financial, Inc. (Ameriprise Financial, formerly American Express
Financial Corporation), serves as the investment manager to the Fund. Under an
investment management services agreement (the IMS Agreement), the investment
manager provides investment advice and other services to the Fund. Throughout
the year, the Fund's Board of Directors (the Board) and the Board's Investment
Review and Contracts Committees monitor these services.

Ameriprise Financial had served as investment manager to the Fund until Sept.
29, 2005. On that date, and pursuant to the consent of the Board, Ameriprise
Financial transferred its rights, title, and interest and its burdens and
obligations under the IMS Agreement to RiverSource, its wholly-owned subsidiary.

Each year, the Board determines whether to continue the IMS Agreement by
evaluating the quality and level of services received and the costs associated
with those services. To assist the Board in making this determination, the
investment manager prepares detailed reports for the Board and its Contracts
Committee in March and April and provides data prepared by independent
organizations. The Board gives considerable weight to the work, deliberations
and conclusions of the Contracts and Investment Review Committees in determining
whether to continue the IMS Agreement.

BACKGROUND

This past year, prior to the Board's annual review process, on Feb. 1, 2005,
American Express Company, the former parent of Ameriprise Financial, announced
its intention to pursue a spin-off of Ameriprise Financial by distributing
shares of the common stock of Ameriprise Financial to shareholders of American
Express Company. Following this announcement, the Board determined to proceed
with its annual review process and, after thorough review of the reports and
data provided, at a meeting held in person on April 14, 2005, the Board,
including all of its independent members, determined that the quality and level
of advisory services provided pursuant to the IMS Agreement were satisfactory
and that fees were fair and reasonable. However, in light of the announced plans
of the spin-off, the Board approved continuation of the IMS Agreement with
Ameriprise Financial for only an interim period ending on the later of (i) the
effective date of the spin-off; or (ii) the approval of a new IMS Agreement with
Ameriprise Financial (or its subsidiary) by the shareholders of the Fund, but in
no event for a period longer than one year.

- --------------------------------------------------------------------------------
44 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

During the course of the six-month period following the April 2005 meeting, the
Board evaluated whether to approve new investment management services agreements
for each of the funds within the Ameriprise Financial fund complex (together,
the Funds) with post-spin Ameriprise Financial (or RiverSource). Independent
counsel, Schulte Roth & Zabel LLP (Schulte), assisted the Boards in fulfilling
their statutory and other responsibilities associated with the spin-off and the
resulting consideration of new contracts, including the new IMS Agreement. The
Board and its committees were provided with a wealth of written and oral
information in this regard. Furthermore, in connection with the Board's
considerations as to whether post-spin Ameriprise Financial, as an entity
independent from American Express Company, would be capable of continuing to
provide a high quality of services to the Funds, the Board's independent members
retained their own financial adviser, Credit Suisse First Boston LLC (CSFB), to
assist them in analyzing the capital adequacy of post-spin Ameriprise Financial.
(The costs of independent counsel and CSFB and of additional meetings of the
Boards were borne by Ameriprise Financial as part of the commitment of the
American Express Company to ensure a complete and thorough review of the
proposed spin-off and its effect on the services provided by Ameriprise
Financial and its subsidiaries.) At a meeting of the Board held on Sept. 8,
2005, the Board, including all of its independent members, approved, and
recommended that shareholders approve, a proposed new IMS Agreement with
RiverSource (the New IMS Agreement). A meeting of the Fund's shareholders is
expected to be held on Feb. 15, 2006 to consider approval of the New IMS
Agreement. If approved, the New IMS Agreement would take effect shortly after
the shareholder meeting. The following section, "Board Considerations Related to
the New IMS Agreement," provides a detailed discussion of the Board's
considerations and determinations respecting the New IMS Agreement.

BOARD CONSIDERATIONS RELATED TO THE NEW IMS AGREEMENT

In carrying out its legal responsibilities associated with the consideration of
the New IMS Agreement, the Board evaluated the following factors:

NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE
FINANCIAL (AND ITS SUBSIDIARIES)

The Board recognized that only a few months had passed since its April 2005
conclusion that the nature, extent and quality of services provided by
Ameriprise Financial were satisfactory and consistent with those that would be
expected for a fund family of the size of the Funds and its determination to
renew the IMS Agreement for the interim period. However, the Board also
recognized the need to supplement this assessment with an evaluation of whether
the spin-off or other factors would result in changes to the advisory services
being provided under the current IMS Agreement.

- --------------------------------------------------------------------------------
45 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

The Board focused its evaluation on the following factors potentially impacting
the nature, extent and quality of advisory services to be provided by Ameriprise
Financial: (i) Ameriprise Financial's projected capital structure and capital
adequacy as a stand-alone entity; (ii) its legal and regulatory risks; (iii) its
ability to retain and attract personnel; and (iv) its ability to successfully
re-brand its products and services. Based on extensive presentations and reports
by Ameriprise Financial, CSFB and Schulte, the Board concluded that the proposed
capital structure (which includes certain indemnification commitments made by
American Express Company) should enable RiverSource to continue to provide a
high quality and level of advisory services to the Fund. In making this
determination, the Board took into account representations by management of
Ameriprise Financial that projected capital levels would allow Ameriprise
Financial and RiverSource to meet legal and compliance responsibilities, build
their distribution network, pursue technological upgrades, make capital
commitments necessary to retain and attract key personnel devoted to legal and
compliance responsibilities, portfolio management and distribution, and pursue
smaller asset management acquisitions to help grow the asset management
business. The Board accorded significant weight to CSFB's confirmation as to the
reasonableness of the proposed capital structure. The Board also considered the
fact that there were no expected departures of key personnel involved in the
portfolio management, operations and marketing of the Funds as a result of the
announcement of the spin-off.

The Board concluded that, based on all of the materials and information
provided, post-spin Ameriprise Financial (including RiverSource) would be in a
position to continue to provide a high quality and level of advisory services to
the Fund.

INVESTMENT PERFORMANCE

The Board next focused on investment performance. The Board reviewed reports
documenting the Fund's performance over one-, three- and/or five-year periods,
as well as the entire period during which its current portfolio manager has
managed the Fund, and compared to relevant Lipper and market indices. The Board
took into account its determination in April 2005 that investment performance
met expectations.

The Board also considered that it had been receiving monthly performance reports
for the Fund and that there had been no significant deviations from April's
overall performance data.

- --------------------------------------------------------------------------------
46 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

COST OF SERVICES PROVIDED

The Board evaluated comparative fees and the costs of services under the current
IMS Agreement and the New IMS Agreement, including fees charged by Ameriprise
Financial (including RiverSource and other subsidiaries) to institutional
clients as well as those paid to subadvisers. The Board studied RiverSource's
effort (i.e., its "pricing philosophy") to set substantially all Funds' total
expense ratios at or below the median expense ratio of comparable mutual funds
(as compiled by Lipper). The Board observed that the proposed advisory fee
changes are designed to work in tandem with proposed changes to administrative
services fees. It also noted that RiverSource has agreed to voluntarily impose
expense caps or waivers to achieve this pricing objective whenever the expense
ratio exceeded the median expense ratio by more than three basis points (unless
the higher ratio was due to the impact of the performance fee adjustment or was
due to the added costs associated with having subadvisers manage the Fund). The
Board considered that advisory fees under the New IMS Agreement would stay the
same. The Board also took into account the effect of the proposed performance
incentive adjustment on the advisory fee. In this regard, the Board recalled its
past determinations regarding the appropriateness of (i) the use of the relevant
index for the performance comparison; (ii) the methodology for determining when
the Board may change an index used to calculate the performance incentive
adjustment; (iii) the periods used for averaging the Fund's assets and computing
investment performance; and (iv) the length of the period over which performance
is computed. Furthermore, the Board considered that there was limited
opportunity for the Fund to achieve large-scale growth and thus provide
RiverSource with potential economies of scale.

The Board next considered the expected profitability to Ameriprise Financial and
RiverSource derived from their relationship with the Fund, recalling the April
2005 determination that the profitability level was appropriate. The Board noted
that projected profitability of Ameriprise Financial would allow it to operate
effectively and, at the same time, reinvest in RiverSource and its other asset
management businesses. The Board also considered that the proposed changes in
advisory fees and the mergers of certain other Funds would result in revenue
gains to Ameriprise Financial, but that these increases would not materially
alter profit margins due to expected increases in costs associated with the
spin-off, particularly re-branding and separation. CSFB also reported that
Ameriprise Financial's projected level of return on equity was generally
reasonable in light of the returns on equity of its industry competitors. In
evaluating profitability, the Board also considered the benefits Ameriprise
Financial obtains through the use of commission dollars paid on portfolio
transactions for the Fund and from other business relationships that result from
managing the Fund. The Board also considered the fees charged by Ameriprise
Financial (and its subsidiaries) to institutional clients as well as the fees
paid to, and charged by, subadvisers, noting the differences in services
provided in each case. In light of these considerations, the Board concluded
that projected profitability levels were appropriate.

- --------------------------------------------------------------------------------
47 -- RIVERSOURCE GLOBAL EQUITY FUND -- 2005 ANNUAL REPORT
<Page>

ECONOMIES OF SCALE

The Board also considered the "breakpoints" in fees that would be triggered as
Fund net asset levels grew and the extent to which shareholders would benefit
from such growth. The Board observed that the revised fee schedules under the
proposed New IMS Agreement would continue to provide breakpoints similar to
those in place pursuant to the current IMS Agreement. Accordingly, the Board
concluded that the proposed New IMS Agreement provides adequate opportunity for
shareholders to realize benefits as Fund assets grow.

OTHER CONSIDERATIONS

In addition, the Board accorded weight to the fact that, under the New IMS
Agreement, RiverSource Investments is held to a higher standard of care than
under the current IMS Agreement. The Board also noted Ameriprise Financial's
commitment to a culture that adheres to ethical business practice, assigns
accountability to senior management and seeks to identify conflicts and propose
appropriate action to minimize the risks posed by the conflicts.

Furthermore, the Board recognized that it was not limited to considering
management's proposed New IMS Agreement. In this regard, the Board evaluated the
circumstances under which it would consider the retention of an investment
adviser different from RiverSource Investments. The Board concluded, based on
its consultation with independent counsel, that pursuing the retention of a
different adviser was not necessary, primarily because, in its best judgment,
Ameriprise Financial continues to be basically the same organization (from a
functional and managerial standpoint) as it was prior to the spin-off. The Board
reasoned that shareholders purchased shares of the Fund with an expectation that
the current investment advisory organization would be servicing the Fund.

Investment products, including shares of mutual funds, involve investment risks
including possible loss of principal and fluctuation in value.

The RiverSource Global Technology Fund is a narrowly-focused sector fund and it
may exhibit higher volatility than funds with broader investment objectives.

International investing involves increased risk and volatility, not typically
associated with domestic investing, due to changes in currency exchange rates,
foreign government regulations, differences in auditing and accounting
standards, potential political and economic instability, limited liquidity, and
volatile prices. The risks of international investing are particularly
significant in emerging markets.

Stocks of small- and mid-capitalization companies involve substantial risk.
Historically, these stocks have experienced greater price volatility than stocks
of larger companies, and they can be expected to do so in the future.

Fund holdings are subject to change.

QUESTIONS & ANSWERS

                            WITH PORTFOLIO MANAGEMENT

BELOW, PORTFOLIO MANAGER NINA HUGHES DISCUSSES THE FUND'S RESULTS AND
POSITIONING FOR THE FISCAL YEAR ENDED OCT. 31, 2005.

Q:   HOW DID RIVERSOURCE GLOBAL TECHNOLOGY FUND PERFORM FOR THE 12 MONTHS ENDED
     OCT. 31, 2005?

A:   RiverSource Global Technology Fund's Class A shares advanced 8.74%
     (excluding sales charge) for the 12 months ended Oct. 31, 2005. This
     outpaced the Fund's benchmark, the unmanaged Goldman Sachs Technology
     Index(R) Composite Index (GSTI(R) Composite Index), which rose 6.20%. The
     Fund underperformed its peer group, represented by the Lipper Science and
     Technology Funds Index, which rose 9.10% over the same period.

Q:   WHAT FACTORS MOST SIGNIFICANTLY AFFECTED PERFORMANCE DURING THE FISCAL
     YEAR?

A:   Global equity markets delivered strong returns over the course of the past
     year, although technology, in general, was not one of the best performing
     sectors. The Fund successfully navigated this market environment. Effective
     positioning in the semiconductor industry was largely responsible for the
     Fund's outperformance of its benchmark.

     At the start of the fiscal period, there was widespread skepticism about
     the outlook for semiconductors, particularly due to high inventory levels
     in late 2004. We believed the negative sentiment was excessive and that
     inventory issues would be resolved. In addition, we thought semiconductor
     companies could benefit from steady economic growth and from expansion
     opportunities in areas such as high definition TVs, multi-media and
     wireless components. We established significant positions in semiconductor
     companies where we thought the balance of reward and risk was very
     compelling. In our view, any good news for the economy or the industry was
     likely to make this positioning particularly effective and, in fact, a
     larger-than-benchmark allocation to semiconductors was the largest
     contributor to the Fund's relative performance.

     The Fund's positioning in the internet software and services group was less
     effective. We had de-emphasized service stocks, which performed very well
     during the period. Although we were not betting against the services group,
     we thought there were other technology areas that held more promise for the
     Fund.

     Stock selection in the computers and peripherals group also detracted from
     relative performance primarily due to a significant holding in Lexmark
     International, a printing and paper company that failed to execute its
     business model in this period.

QUESTIONS & ANSWERS

>    EFFECTIVE POSITIONING IN THE SEMICONDUCTOR INDUSTRY WAS LARGELY RESPONSIBLE
     FOR THE FUND'S OUTPERFORMANCE OF ITS BENCHMARK.

     In terms of individual holdings, Macromedia, a software firm that provides
     multi-media for the internet, was the largest positive contributor on an
     absolute and relative basis. Other investors were avoiding this stock
     because they feared that a near-term product line transition would
     negatively impact earnings. However, we had done a great deal of research
     on this company and were aware that Macromedia was expanding into cell
     phones in Asia. We believed this foreign exposure would offset any
     transition-related weakness in the company's domestic earnings. As a
     result, we built a sizeable position at an attractive valuation. In April
     2005, Adobe announced its intent to acquire Macromedia and thus we
     benefited from our positioning even sooner than anticipated.

     Broadcom, a semiconductor stock, also had a positive impact on absolute
     performance. This company develops semiconductor chips for many of the
     growth drivers in the technology sector. They produce chips used for Voice
     over Internet Protocols, broadband, Bluetooth technology and cell phones.
     The company has broad product space, but the stock was at an attractive
     price level following a reduction in management's earnings guidance. We
     established a meaningful position because we did not think the company was
     in a weak position, but rather that expectations just had to be reset.
     During the period, the Fund benefited from this decision.

     A third major contributor to absolute return was internet search engine
     Google. When Google initially went public last year, there was some

QUESTIONS & ANSWERS

- -    WE BELIEVE THERE ARE STILL SOME GREAT GROWTH DRIVERS IN THE TECHNOLOGY
     INDUSTRY. IN PARTICULAR, WE THINK CONSUMERS WILL ULTIMATELY BE A MAJOR
     DRIVER OF GROWTH.

     skepticism as to whether the company and management team could function
     successfully as a public company. However, they have been proving
     themselves and are incorporating other growth drivers into their business
     model. The company delivered both top line and bottom line growth and, as a
     result, the stock has performed extremely well.

     Conversely, network provider Cisco Systems was one of the most significant
     individual detractors for the period. We took a position in the stock,
     believing that for a large cap company with a great management team, it was
     at an attractive valuation. The company subsequently reduced its earnings
     guidance. Although Cisco's top line growth appears to be fairly steady, we
     haven't seen any growth coming back to the networking industry, so we
     reduced the portfolio's position.

     We have already mentioned Lexmark International, a provider of printing
     products and supplies for laser jets and other types of printers, which was
     another key detractor. The stock of this company traded at an attractive
     valuation and we anticipated that earnings would be stable, but not
     accelerate. However, Lexmark's earnings are highly dependent on top line
     growth and when that growth fell just a little bit short, the company was
     forced to sharply cut its earnings estimate. We chose to eliminate the
     stock because there has been some deceleration in the printing industry as
     people shift from printing photos at home to sending them out. We don't see
     evidence that Lexmark is adapting its business model to the changing
     environment, so we foresee no growth potential and, therefore, think the
     Fund can benefit more from other growth opportunities.

QUESTIONS & ANSWERS

     Internet auction company eBay was another detractor. We like eBay's story,
     we consider their business model dynamic and are impressed with eBay's
     expansion beyond person to person trading into other areas such as selling
     cars. However, eBay missed its earnings estimate in the middle of the year
     and the stock was hit hard. We trimmed the portfolio's position at that
     time and in retrospect, that was an inopportune time to sell. The stock has
     since advanced as eBay has continued to execute effectively and its
     business model remains intact.

Q:   WHAT CHANGES DID YOU MAKE TO THE FUND AND HOW IS IT CURRENTLY POSITIONED?

A:   We have reduced the portfolio's semiconductor position, moving from a
     larger-than-benchmark allocation to a more neutral weighting. Instead we
     have placed more emphasis on software and internet stocks, while remaining
     underweight in service-related stocks. Semiconductors advanced sharply this
     past year and valuations are no longer as attractive to us. For the
     industry to repeat its recent strong performance, we believe consumers
     would need to spend significantly in the upcoming months and we are
     somewhat concerned that spending might be more restrained, given high oil
     prices and a softening housing market. We aren't negative on
     semiconductors, but we don't want to be over-allocated to this group.

     Regarding the portfolio's increased software emphasis, we found software
     valuations very attractive following the industry's traditional summer
     weakness. In addition, we wanted to be positioned to benefit from
     increasing merger and acquisition activity in the software arena.

     During the period, we began building a position in telecommunications
     company Sprint Nextel because we believe synergies related to Sprint's
     merger with Nextel haven't been fully realized yet. In general, we see
     opportunities in telecommunications services and we consider Sprint Nextel
     one of the better companies within that group.

     We sold a substantial portion of our holdings of Dell, which had been one
     of the largest positions in the Fund. We had continued to see evidence that
     Dell was not executing as well as it had in the past and was facing greater
     competition from IBM and Hewlett-Packard.

<Page>

QUESTIONS & ANSWERS

Q:   HOW DO YOU INTEND TO MANAGE THE FUND IN THE COMING MONTHS?

A:   We believe there are still some great growth drivers in the technology
     industry. In particular, we think consumers will ultimately be a major
     driver of growth. Cell phones are using more technology and offer more
     multi-media capabilities. In addition, other consumer devices such as the
     iPod and digital TVs have more semi-conductor content in them. Sales of
     digital TVs have been accelerating and with the cost of LCD monitors
     decreasing we are beginning to see increased volume of units being sold.
     These are excellent drivers for technology. However, we are watching these
     areas closely because, as we mentioned above, we are somewhat wary of
     consumer spending patterns. Although we have not seen any evidence that
     consumer spending is declining, external pressures such as high oil prices
     and weaker housing prices indicate that we should be careful. Consequently,
     we have pared back consumer-focused positions. Within the semi-conductor
     group, we have begun shifting to less expensive semiconductor stocks, but
     we continue to see growth longer term because semiconductor use is so
     widespread in diverse products such as cars and cell phones.

     The U.S. economy seems to be on track for further improvement, although the
     improvement may be slow. We think corporate enterprise spending remains
     pretty stable. Such spending is usually quite strong in the fourth quarter
     and we see no evidence this won't be the case in the final quarter of 2005.

NOTES TO FINANCIAL STATEMENTS

WORLD TECHNOLOGIES PORTFOLIO

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

World Technologies Portfolio (the Portfolio) is a series of World Trust (the
Trust) and is registered under the Investment Company Act of 1940 (as amended)
as a non-diversified, open-end management investment company. The Portfolio
invests in equity securities of companies in the information technology industry
throughout the world. The Declaration of Trust permits the Trustees to issue
non-transferable interests in the Portfolio.

The Portfolio'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 securities are normally traded. Pursuant to procedures adopted by the
Board of Trustees of the portfolios, Ameriprise Financial, Inc. (Ameriprise
Financial) (formerly American Express Financial Corporation) utilizes Fair Value
Pricing (FVP). FVP determinations are made in good faith in accordance with
these procedures. If a development or event is so significant that there is a
reasonably high degree of certainty that the effect of the development or event
has actually caused the closing price to no longer reflect the actual value, the
closing prices, as determined at the close of the applicable foreign market, may
be adjusted to reflect the fair value of the affected foreign securities as of
the close of the New York Stock Exchange. Significant events include material
movements in the U.S. securities markets prior to the opening of foreign markets
on the following trading day. FVP results in an estimated price that reasonably
reflects the current market conditions in order to value the portfolio holdings
such that shareholder transactions receive a fair net asset value. 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.

- --------------------------------------------------------------------------------
18 -- RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2005 ANNUAL REPORT
<Page>

ILLIQUID SECURITIES

At Oct. 31, 2005, investments in securities included issues that are illiquid
which the Fund currently limit to 10% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at Oct. 31, 2005 was
$68,110 representing 0.04% of net assets. These securities are valued at fair
value according to methods selected 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 Portfolio 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
Portfolio 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 Portfolio gives up the opportunity for
profit if the market price of the security increases. The risk in writing a put
option is that the Portfolio 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 Portfolio pays a premium whether or not the option is exercised. The
Portfolio 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 Portfolio
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 Portfolio may buy
and sell financial futures contracts traded on any U.S. or foreign exchange. The
Portfolio 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 Portfolio 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 Portfolio 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 Portfolio recognizes a realized gain or loss when the
contract is closed or expires.

- --------------------------------------------------------------------------------
19 -- RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2005 ANNUAL REPORT
<Page>

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 Oct. 31, 2005, foreign currency holdings were entirely
comprised of Taiwan dollars.

The Portfolio 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 Portfolio and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Portfolio is subject to the credit risk that
the other party will not complete its contract obligations.

GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

For federal income tax purposes the Portfolio qualifies as a partnership and
each investor in the Portfolio is treated as the owner of its proportionate
share of the net assets, income, expenses and realized and unrealized gains and
losses of the Portfolio. As a "pass-through" entity, the Portfolio therefore
does not pay any income dividends or capital gain distributions.

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. FEES AND EXPENSES

The Trust, on behalf of the Portfolio, has an Investment Management Services
Agreement with RiverSource Investments, LLC (the Investment Manager) to manage
its portfolio. Prior to Oct. 1, 2005, investment management services were
provided by Ameriprise Financial. Under this agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is a percentage of the Portfolio's average daily net assets that declines from
0.72% to 0.595% annually as the Portfolio'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 RiverSource Global
Technology 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 $197,924 for
the year ended Oct. 31, 2005.

Under the agreement, the Trust also pays taxes, brokerage commissions and
nonadvisory expenses, which include custodian fees, audit and certain legal
fees, fidelity bond premiums, registration fees for units, office expenses,
consultants' fees, compensation of trustees, corporate filing fees, expenses
incurred in connection with lending securities of the Portfolio and any other
expenses properly payable by the Trust or Portfolio and approved by the Board.

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

During the year ended Oct. 31, 2005, the Portfolio's custodian fees were reduced
by $3,218 as a result of earnings credits from overnight cash balances. The
Portfolio also pays custodian fees to Ameriprise Trust Company (formerly
American Express Trust Company), an affiliate of Ameriprise Financial.

According to a Placement Agency Agreement, Ameriprise Financial Services, Inc.
(formerly American Express Financial Advisors Inc.) acts as placement agent of
the Trust's units.

3. SECURITIES TRANSACTIONS

THE BOARD OF TRUSTEES AND UNITHOLDERS
WORLD TRUST

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities, of World Technologies Portfolio (a
series of World Trust) as of October 31, 2005, the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period ended October 31, 2005 and the
financial highlights for each of the years in the five-year period ended October
31, 2005. These financial statements and the financial highlights are the
responsibility of portfolio management. Our responsibility is to express an
opinion on these financial statements and the financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers or by other appropriate auditing procedures. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of World
Technologies Portfolio as of October 31, 2005, and the results of its
operations, changes in its net assets and the financial highlights for each of
the periods stated in the first paragraph above, in conformity with U.S.
generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

RIVERSOURCE GLOBAL TECHNOLOGY FUND (FORMERLY AXP GLOBAL TECHNOLOGY FUND)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RiverSource Global Technology Fund (a series of AXP Global Series, Inc.) is
registered under the Investment Company Act of 1940 (as amended) as a
non-diversified, open-end management investment company. AXP 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 offers Class A, Class B, Class C and Class Y 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 Y shares have no sales charge and are offered only to qualifying
     institutional investors.

The Fund offers an additional class of shares, Class I, exclusively to certain
institutional investors. Class I shares have no sales charge and are made
available through a separate prospectus supplement provided to investors
eligible to purchase the shares. At Oct. 31, 2005, Ameriprise Financial owned
100% of Class I shares, which represents 0.01% of the Fund's net assets.

All classes of shares have identical voting, dividend and liquidation rights.
The distribution fee, transfer agency fees and service fee (class specific
expenses) 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.

INVESTMENT IN WORLD TECHNOLOGIES PORTFOLIO

The Fund invests all of its assets in World Technologies Portfolio (the
Portfolio), a series of World Trust (the Trust), an open-end investment company
that has the same objectives as the Portfolio. The Portfolio invests in equity
securities of companies in the information technology industry throughout the
world.

The Fund records daily its share of the Portfolio's income, expenses and
realized and unrealized gains and losses. The financial statements of the
Portfolio are included elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

The Fund records its investment in the Portfolio at the value that is equal to
the Fund's proportionate ownership interest in the Portfolio's net assets. The
percentage of the Portfolio owned by the Fund at Oct. 31, 2005 was 99.98%.

The Fund's Board approved the withdrawal of the Fund's assets from the
Portfolio. As of Dec. 6, 2005, the Fund invests directly in and manages its own
portfolio of securities rather than investing in the Portfolio.

- --------------------------------------------------------------------------------
27 -- RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2005 ANNUAL REPORT
<Page>

All securities held by the Portfolio 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. Pursuant
to procedures adopted by the Board of Trustees of the portfolios, Ameriprise
Financial utilizes Fair Value Pricing (FVP). FVP determinations are made in good
faith in accordance with these procedures. If a development or event is so
significant that there is a reasonably high degree of certainty that the effect
of the development or event has actually caused the closing price to no longer
reflect the actual value, the closing prices, as determined at the close of the
applicable foreign market, may be adjusted to reflect the fair value of the
affected foreign securities as of the close of the New York Stock Exchange.
Significant events include material movements in the U.S. securities markets
prior to the opening of foreign markets on the following trading day. FVP
results in an estimated price that reasonably reflects the current market
conditions in order to value the portfolio holdings such that shareholder
transactions receive a fair net asset value. 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.

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.

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 all sections of the Internal Revenue Code
that apply 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.

- --------------------------------------------------------------------------------
28 -- RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2005 ANNUAL REPORT
<Page>

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been increased by
$2,220,414 and accumulated net realized loss has been increased by $8,654
resulting in a net reclassification adjustment to decrease paid-in capital by
$2,211,760.

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

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.

2. EXPENSES AND SALES CHARGES

In addition to the expenses allocated from the Portfolio, the Fund accrues its
own expenses as follows:

The Fund has an agreement with Ameriprise Financial to provide administrative
services. Under the current 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. Prior to Oct. 1, 2005, the fee
percentage of the Fund's average daily net assets declined from 0.06% to 0.035%
annually as the Fund's assets increased. A minor portion of additional
administrative service expenses paid by the Fund are consultants' fees and fund
office expenses. Under this agreement, the Fund also pays taxes, audit and
certain legal fees, registration fees for shares, compensation of board members,
corporate filing fees and any other expenses properly payable by the Fund and
approved by the Board.

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.

Under a separate Transfer Agency Agreement, RiverSource Service Corporation
(formerly American Express Client 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
- -  Class Y $17.50

The incremental transfer agency fee is the amount charged to the specific
classes for the additional expense above the fee for Class Y.

Class I pays 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.

Beginning May 20, 2005, the Transfer Agent is entitled to charge 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. (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 up to 0.25% of the Fund's average daily net assets attributable to
Class A shares and up to 1.00% for Class B and Class C shares.

Under a Shareholder Service Agreement, the Fund pays the Distributor a fee for
service provided to shareholders by financial advisors and other servicing
agents. The fee is calculated at a rate of 0.10% of the Fund's average daily net
assets attributable to Class Y shares.

- --------------------------------------------------------------------------------
30 -- RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2005 ANNUAL REPORT
<Page>

Sales charges received by the Distributor for distributing Fund shares were
$228,669 for Class A, $99,646 for Class B and $455 for Class C for the year
ended Oct. 31, 2005.

The Investment Manager and its affiliates have agreed to waive certain fees and
expenses until Oct. 31, 2005. Under this agreement, net expenses will not exceed
1.82% for Class A, 2.59% for Class B, 2.59% for Class C, 1.13% for Class I and
1.63% for Class Y of the Fund's average daily net assets. Beginning Oct. 1,
2005, a new agreement to waive certain fees and expenses is effective until Oct.
31, 2006, such that net expenses, before giving effect to any performance
incentive adjustment, will not exceed 1.82% for Class A, 2.59% for Class B,
2.59% for Class C, 1.13% for Class I and 1.63% for Class Y of the Fund's average
daily net assets.

During the year ended Oct. 31, 2005, the Fund's transfer agency fees were
reduced by $8,334 as a result of earnings credits from overnight cash balances.

4. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary
funding of shareholder redemptions or for other temporary or emergency purposes.
The agreement went into effect Sept. 20, 2005. 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 0.07%
per annum. Prior to this agreement, the Fund had a revolving credit agreement
that permitted borrowings up to $500 million with The Bank of New York. The Fund
had no borrowings outstanding during the year ended Oct. 31, 2005.

5. CAPITAL LOSS CARRY-OVER

For federal income tax purposes the Fund had a capital loss carry-over of
$386,068,821 at Oct. 31, 2005, that if not offset by capital gains will expire
as follows:

<Table>
<Caption>
                               2009                      2010

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.

REPORT OF INDEPENDENT
                                               REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD AND SHAREHOLDERS
AXP GLOBAL SERIES, INC.

We have audited the accompanying statement of assets and liabilities of
RiverSource Global Technology Fund (a series of AXP Global Series, Inc.) as of
October 31, 2005, the related statement of operations for the year then ended,
the statements of changes in net assets for each of the years in the two-year
period ended October 31, 2005, and the financial highlights for each of the
years in the five-year period ended October 31, 2005. These financial statements
and the financial highlights are the responsibility of fund management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and the financial highlights are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
RiverSource Global Technology Fund as of October 31, 2005, and the results of
its operations, changes in its net assets and the financial highlights for each
of the periods stated in the first paragraph above, in conformity with U.S.
generally accepted accounting principles.

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, including management fees; distribution and service (12b-1) fees; and
other Fund 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.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended Oct. 31, 2005.

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 185/365 (to reflect the one-half year period).
(b)  Based on the actual return for the six months ended Oct. 31, 2005: +13.71%
     for Class A, +13.73% for Class B, +12.99% for Class C, +14.20% for Class I
     and +13.64% for Class Y.
(c)  Effective Oct. 1, 2005, the Fund's Board of Directors approved a change to
     the fee schedule under the Administrative Services Agreement between
     Ameriprise Financial and the Fund. The Investment Manager and its
     affiliates have contractually agreed to waive certain fees and to absorb
     certain expenses until Oct. 31, 2006, unless sooner terminated at the
     discretion of the Board. Under this expense cap/fee waiver agreement, net
     expenses before giving effect to any performance incentive adjustment, will
     not exceed 1.82% for Class A; 2.59% for Class B; 2.59% for Class C; 1.13%
     for Class I; and 1.63% for Class Y. If the revised fee schedule under the
     Administrative Services Agreement and the cap/fee waiver agreement had been
     in place for the entire six-month period ended Oct. 31, 2005, the actual
     and hypothetical expenses paid would have been the same as those presented
     above.

<Page>

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

RiverSource Investments, LLC (RiverSource), a wholly-owned subsidiary of
Ameriprise Financial, Inc. (Ameriprise Financial, formerly American Express
Financial Corporation), serves as the investment manager to the Fund. Under an
investment management services agreement (the IMS Agreement), the investment
manager provides investment advice and other services to the Fund. Throughout
the year, the Fund's Board of Directors (the Board) and the Board's Investment
Review and Contracts Committees monitor these services.

Ameriprise Financial had served as investment manager to the Fund until Sept.
29, 2005. On that date, and pursuant to the consent of the Board, Ameriprise
Financial transferred its rights, title, and interest and its burdens and
obligations under the IMS Agreement to RiverSource, its wholly-owned subsidiary.

Each year, the Board determines whether to continue the IMS Agreement by
evaluating the quality and level of services received and the costs associated
with those services. To assist the Board in making this determination, the
investment manager prepares detailed reports for the Board and its Contracts
Committee in March and April and provides data prepared by independent
organizations. The Board gives considerable weight to the work, deliberations
and conclusions of the Contracts and Investment Review Committees in determining
whether to continue the IMS Agreement.

BACKGROUND

This past year, prior to the Board's annual review process, on Feb. 1, 2005,
American Express Company, the former parent of Ameriprise Financial, announced
its intention to pursue a spin-off of Ameriprise Financial by distributing
shares of the common stock of Ameriprise Financial to shareholders of American
Express Company. Following this announcement, the Board determined to proceed
with its annual review process and, after thorough review of the reports and
data provided, at a meeting held in person on April 14, 2005, the Board,
including all of its independent members, determined that the quality and level
of advisory services provided pursuant to the IMS Agreement were satisfactory
and that fees were fair and reasonable. However, in light of the announced plans
of the spin-off, the Board approved continuation of the IMS Agreement with
Ameriprise Financial for only an interim period ending on the later of (i) the
effective date of the spin-off; or (ii) the approval of a new IMS Agreement with
Ameriprise Financial (or its subsidiary) by the shareholders of the Fund, but in
no event for a period longer than one year.

During the course of the six-month period following the April 2005 meeting, the
Board evaluated whether to approve new investment management services agreements
for each of the funds within the Ameriprise Financial fund complex (together,
the Funds) with post-spin Ameriprise Financial (or RiverSource). Independent
counsel, Schulte Roth & Zabel LLP (Schulte), assisted the Boards in fulfilling
their statutory and other responsibilities associated with the spin-off and the
resulting consideration of new contracts, including the new IMS Agreement. The
Board and its committees were provided with a wealth of written and oral
information in this regard. Furthermore, in connection with the Board's
considerations as to whether post-spin Ameriprise Financial, as an entity
independent from American Express Company, would be capable of continuing to
provide a high quality of services to the Funds,

- --------------------------------------------------------------------------------
41 -- RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2005 ANNUAL REPORT
<Page>

the Board's independent members retained their own financial adviser, Credit
Suisse First Boston LLC (CSFB), to assist them in analyzing the capital adequacy
of post-spin Ameriprise Financial. (The costs of independent counsel and CSFB
and of additional meetings of the Boards were borne by Ameriprise Financial as
part of the commitment of American Express Company to ensure a complete and
thorough review of the proposed spin-off and its effect on the services provided
by Ameriprise Financial and its subsidiaries.) At a meeting of the Board held on
Sept. 8, 2005, the Board, including all of its independent members, approved,
and recommended that shareholders approve, a proposed new IMS Agreement with
RiverSource (the New IMS Agreement). A meeting of the Fund's shareholders is
expected to be held on Feb. 15, 2006 to consider approval of the New IMS
Agreement. If approved, the New IMS Agreement would take effect shortly after
the shareholder meeting. The following section, "Board Considerations Related to
the New IMS Agreement," provides a detailed discussion of the Board's
considerations and determinations respecting the New IMS Agreement.

BOARD CONSIDERATIONS RELATED TO THE NEW IMS AGREEMENT

In carrying out its legal responsibilities associated with the consideration of
the New IMS Agreement, the Board evaluated the following factors:

NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE
FINANCIAL (AND ITS SUBSIDIARIES)

The Board recognized that only a few months had passed since its April 2005
conclusion that the nature, extent and quality of services provided by
Ameriprise Financial were satisfactory and consistent with those that would be
expected for a fund family of the size of the Funds and its determination to
renew the IMS Agreement for the interim period. However, the Board also
recognized the need to supplement this assessment with an evaluation of whether
the spin-off or other factors would result in changes to the advisory services
being provided under the current IMS Agreement.

The Board focused its evaluation on the following factors potentially impacting
the nature, extent and quality of advisory services to be provided by Ameriprise
Financial: (i) Ameriprise Financial's projected capital structure and capital
adequacy as a stand-alone entity; (ii) its legal and regulatory risks; (iii) its
ability to retain and attract personnel; and (iv) its ability to successfully
re-brand its products and services. Based on extensive presentations and reports
by Ameriprise Financial, CSFB and Schulte, the Board concluded that the proposed
capital structure (which includes certain indemnification commitments made by
American Express Company) should enable RiverSource to continue to provide a
high quality and level of advisory services to the Fund. In making this
determination, the Board took into account representations by management of
Ameriprise Financial that projected capital levels would allow Ameriprise
Financial and RiverSource to meet legal and compliance responsibilities, build
their distribution network, pursue technological upgrades, make capital
commitments necessary to retain and attract key personnel devoted to legal and
compliance responsibilities, portfolio management and distribution, and pursue
smaller asset management acquisitions to help grow the asset management
business. The Board accorded significant weight to CSFB's confirmation as to the
reasonableness of the proposed capital structure. The Board also considered the
fact that there were no expected departures of key personnel involved in the
portfolio management, operations and marketing of the Funds as a result of the
announcement of the spin-off.

- --------------------------------------------------------------------------------
42 -- RIVERSOURCE GLOBAL TECHNOLOGY FUND -- 2005 ANNUAL REPORT
<Page>

The Board concluded that, based on all of the materials and information
provided, post-spin Ameriprise Financial (including RiverSource) would be in a
position to continue to provide a high quality and level of advisory services to
the Fund.

INVESTMENT PERFORMANCE

The Board next focused on investment performance. The Board reviewed reports
documenting the Fund's performance over one-, three- and/or five-year periods,
as well as the entire period during which its current portfolio manager has
managed the Fund, and compared to relevant Lipper and market indices. The Board
took into account its determination in April 2005 that investment performance
met expectations.

The Board also considered that it had been receiving monthly performance reports
for the Fund and that there had been no significant deviations from April's
overall performance data.

COST OF SERVICES PROVIDED

The Board evaluated comparative fees and the costs of services under the current
IMS Agreement and the New IMS Agreement, including fees charged by Ameriprise
Financial (including RiverSource and other subsidiaries) to institutional
clients. The Board studied RiverSource's effort (i.e., its "pricing philosophy")
to set substantially all Funds' total expense ratios at or below the median
expense ratio of comparable mutual funds (as compiled by Lipper). The Board
observed that the proposed advisory fee changes are designed to work in tandem
with proposed changes to administrative services fees. It also noted that
RiverSource has agreed to voluntarily impose expense caps or waivers to achieve
this pricing objective whenever the expense ratio exceeded the median expense
ratio by more than three basis points (unless the higher ratio was due to the
impact of the performance fee adjustment). The Board considered that advisory
fees under the New IMS Agreement would stay the same. The Board also took into
account the effect of the proposed performance incentive adjustment on the
advisory fee. In this regard, the Board recalled its past determinations
regarding the appropriateness of (i) the use of the relevant index for the
performance comparison; (ii) the methodology for determining when the Board may
change an index used to calculate the performance incentive adjustment; (iii)
the periods used for averaging the Fund's assets and computing investment
performance; and (iv) the length of the period over which performance is
computed.

The Board next considered the expected profitability to Ameriprise Financial and
RiverSource derived from their relationship with the Fund, recalling the April
2005 determination that the profitability level was appropriate. The Board noted
that projected profitability of Ameriprise Financial would allow it to operate
effectively and, at the same time, reinvest in RiverSource and its other asset
management businesses. The Board also considered that the proposed changes in
advisory fees and the mergers of certain other Funds would result in revenue
gains to Ameriprise Financial, but that these increases would not materially
alter profit margins due to expected increases in costs associated with the
spin-off, particularly re-branding and separation. CSFB also reported that
Ameriprise Financial's projected level of return on equity was generally
reasonable in light of the returns on equity of its industry competitors. In
evaluating profitability, the Board also considered the benefits Ameriprise
Financial obtains through the use of commission dollars paid on portfolio
transactions for the Fund and from other business relationships that result from
managing the Fund. The Board also considered the fees charged by Ameriprise
Financial (and its subsidiaries) to institutional clients as well as the fees
paid to,

<Page>

and charged by, subadvisers, noting the differences in services provided in each
case. In light of these considerations, the Board concluded that projected
profitability levels were appropriate.

ECONOMIES OF SCALE

The Board also considered the "breakpoints" in fees that would be triggered as
Fund net asset levels grew and the extent to which shareholders would benefit
from such growth. The Board observed that the revised fee schedules under the
proposed New IMS Agreement would continue to provide breakpoints similar to
those in place pursuant to the current IMS Agreement. Accordingly, the Board
concluded that the proposed New IMS Agreement provides adequate opportunity for
shareholders to realize benefits as Fund assets grow.

OTHER CONSIDERATIONS

In addition, the Board accorded weight to the fact that, under the New IMS
Agreement, RiverSource Investments is held to a higher standard of care than
under the current IMS Agreement. The Board also noted Ameriprise Financial's
commitment to a culture that adheres to ethical business practice, assigns
accountability to senior management and seeks to identify conflicts and propose
appropriate action to minimize the risks posed by the conflicts.

Furthermore, the Board recognized that it was not limited to considering
management's proposed New IMS Agreement. In this regard, the Board evaluated the
circumstances under which it would consider the retention of an investment
adviser different from RiverSource Investments. The Board concluded, based on
its consultation with independent counsel, that pursuing the retention of a
different adviser was not necessary, primarily because, in its best judgment,
Ameriprise Financial continues to be basically the same organization (from a
functional and managerial standpoint) as it was prior to the spin-off. The Board
reasoned that shareholders purchased shares of the Fund with an expectation that
the current investment advisory organization would be servicing the Fund.
