(1)  Weighted average life measures a bond's maturity, which takes into
     consideration the possibility that the issuer may call the bond before its
     maturity date.

(2)  Effective duration measures the sensitivity of a security's price to
     parallel shifts in the yield curve (the graphical depiction of the levels
     of interest rates from two years out to 30 years). Positive duration means
     that as rates rise, the price decreases, and negative duration means that
     as rates rise, the price increases.

(3)  Weighted average bond rating represents the average credit quality of the
     underlying bonds in the portfolio.

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

There are risks associated with an investment in a bond fund, including the
impact of interest rates and credit. These and other risk considerations are
discussed in the fund's prospectus. In general, bond prices rise when interest
rates fall and vice versa. This effect is usually more pronounced for
longer-term securities.

Lower-rated bonds generally have more volatile prices and carry more risk to
principal and income than investment grade securities.

Fund holdings are subject to change.

Questions & Answers
                WITH PORTFOLIO MANAGEMENT

Below, the portfolio management team for RiverSource Diversified Bond Fund
(formerly AXP Diversified Bond Fund) discusses the Fund's results and
positioning for the annual period ended Aug. 31, 2005.

Q:  How did RiverSource Diversified Bond Fund perform for the fiscal year?

A:  RiverSource Diversified Bond Fund's Class A shares gained 4.38%, excluding
    sales charge, for the 12 months ended Aug. 31, 2005. The Fund outperformed
    its benchmark, the Lehman Brothers Aggregate Bond Index (Lehman Index),
    which rose 4.15%, and performed in line with the Lipper Intermediate
    Investment Grade Index, representing the Fund's peer group, which advanced
    4.38%.

Q:  What market conditions were present during the annual period?

A:  Overall, the fixed income yield curve flattened significantly during the
    fiscal year, with long-term rates falling while short-term rates rose. This
    dramatic reshaping of the yield curve was driven by the Federal Reserve
    Board's (the Fed) decision to tighten monetary policy a total of eight times
    during the period. This put upward pressure on short-term bond yields, and
    moderate economic growth put downward pressure on intermediate/long-term
    bond yields. Strong global demand for U.S. financial assets -- notably from
    foreign central banks -- also contributed to keeping intermediate bond
    yields low.

    High yield and emerging market debt outperformed other fixed income assets
    during the period, as these sectors benefited from both solid fundamentals
    and a strong demand for the extra yield these sectors historically can
    provide. Investment grade corporate bonds also performed well for the fiscal
    year, but stumbled significantly in March and April.

SEC YIELDS

At Aug. 31, 2005 by class
A: 3.61% B: 3.03% C: 3.04% I: 4.12% Y: 3.95%

At Sept. 30, 2005 by class
A: 3.65% B: 3.08% C: 3.08% I: 4.18% Y: 3.97%

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
performance information.

Questions & Answers

[BEGIN CALLOUT QUOTE]> The Fund's returns were also helped by a modest
position in non-U.S. dollar bonds. [END CALLOUT QUOTE]

    Mortgages performed well during the period because the environment was
    generally positive for mortgages, as volatility declined significantly and
    prepayments were fairly predictable. Somewhat offsetting these positives
    were important changes in the agencies, such as Fannie Mae and Freddie Mac,
    which began to shrink their portfolio of mortgage-backed securities in
    response to increased oversight from Congress. Also, the dramatic flattening
    of the yield curve lessened the incentive for banks and other financers to
    borrow via short rates and invest in longer maturities.

Q:  What factors most significantly affected Fund performance?

A:  On the positive side, the Fund maintained a shorter duration than the Lehman
    Index throughout the period, since we believed interest rates were headed
    higher as the economy gained traction and the Fed continued to tighten
    monetary policy as a result. The Fund's duration was 3.8 years as of Aug.
    31, 2005. In addition, for the first half of the fiscal year, we emphasized
    longer maturity bonds and cash over short- to intermediate-term maturities.
    As the yield curve flattened through the second half of the period, with
    short-term rates rising more than long-term rates, the portfolio benefited
    from this strategy.

    The Fund benefited from its exposure to high quality commercial
    mortgage-backed securities, which are securities based on pools of
    commercial mortgages, and asset-backed securities. The Fund had a sizable
    exposure to investment grade corporate bonds for most of the fiscal year,
    and strong issue selection helped the Fund's results. A modest allocation to
    high yield bonds further boosted the Fund's performance, as this sector as a
    whole performed well during the period.

    The Fund's returns were also helped by a modest position in non-U.S. dollar
    bonds. We successfully were able to add value when the U.S. dollar weakened
    in the latter months of 2004. Although the dollar fully regained its ground
    in the first seven months of 2005, it weakened again in August. As the value
    of the U.S. dollar decreases, the dollar value of foreign investments
    typically increases and vice versa.

- --------------------------------------------------------------------------------
6 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


Questions & Answers

    Detracting somewhat from Fund returns were the Fund's holdings within the
    mortgage sector. The Fund maintained a defensive profile within this sector
    of higher coupon securities and bonds that we believed would hold their
    values as rates migrated higher. However, the path to higher rates was quite
    gradual during the fiscal period. This defensive positioning did not provide
    a significant performance advantage.

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

A:  We kept the Fund's duration shorter than the Lehman Index throughout the
    period, but we made minor adjustments to portfolio duration based on
    changing market conditions.

    As the yield curve flattened dramatically, we reduced the portfolio's
    sensitivity to changes in interest rates. We did this by seeking exposure to
    securities with maturities more evenly distributed across the yield curve.
    In our view, the yield curve flattening had largely run its course.

    The Fund's sector positioning remained generally unchanged. Through the
    year, we did adjust the Fund's exposure to high yield securities in response
    to shifts in the difference between the yields of these securities and U.S.
    Treasuries. We ended the fiscal year with the Fund near its lowest
    allocation to high yield bonds held during the 12 months. Generally, though,
    we continued to favor more conservative alternatives, such as AAA-rated
    commercial mortgage-backed securities, asset-backed securities and certain
    mortgage products, which, in our view, offer attractive yield as well as the
    kind of defensive characteristics we want in the current market environment.

    In all, the Fund's portfolio turnover was high but added value to the
    portfolio. A significant portion of the Fund's 300% turnover rate this past
    fiscal year was the result of "roll" transactions in liquid derivatives and
    U.S. Treasury notes. In the derivative securities, positions in expiring
    contracts are liquidated and simultaneously replaced with positions in new
    contracts with equivalent characteristics. For U.S. Treasury notes, existing
    holdings are sold and newly minted securities with better liquidity are
    purchased. These transactions affect the Fund's turnover rate but do not
    change the risk exposure or result in material transaction costs.

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

A:  We intend to maintain the Fund's duration shorter than that of the
    benchmark, the Lehman Index, for the near term. Our best assessment at this
    time leads us to believe that the devastation caused by Hurricane Katrina
    will have only a transitory impact on the

    U.S. economy overall. We expect energy shortages to be temporary and oil
    prices to recede as refining and production capacities come back in line. We
    expect the Fed to focus on the risks to higher inflation caused by higher
    energy prices, supply-chain disruptions and the strain on resources
    resulting from the massive rescue, relief and rebuilding efforts now
    underway. As a result, we expect the Fed to continue to raise the targeted
    federal funds rate through the balance of 2005.

    We believe fixed income yields will move higher in the months ahead. From a
    sector perspective, we intend to cautiously increase the Fund's allocation
    to investment grade corporate bonds, though, importantly, we continue to be
    very selective in adding names to the portfolio. We intend to maintain our
    position in commercial mortgage-backed securities and asset-backed
    securities because they offer higher yields. In mortgages, we plan to remain
    defensively positioned, emphasizing premium coupons, 15-year mortgages and
    attractive structural attributes. We intend to maintain the Fund's modest
    position in high yield bonds and may increase it if the market offers
    opportunities.

    Finally, we intend to maintain the Fund's moderate exposure to non-U.S.
    dollar bonds. The U.S. dollar's pressured path may experience fits and
    starts with short-lived periods of currency strength. However, we believe
    the U.S. dollar will likely remain at relatively weak levels going forward,
    as we expect the currency's structural problems to continue.

    We will continue to monitor job creation and inflation numbers, as they
    remain key indicators for the economy in the coming months -- especially so
    in the aftermath of Hurricane Katrina. As always, we will maintain a

    larger positions than the Lehman Index in bonds that offer the greatest

9 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


The Fund's Long-term Performance

The chart on the facing page illustrates the total value of an assumed $10,000
investment in RiverSource Diversified Bond Fund Class A shares (from 9/1/95 to
8/31/05) as compared to the performance of two widely cited performance indices,
the Lehman Brothers Aggregate Bond Index and the Lipper Intermediate Investment
Grade Index. In comparing the Fund's Class A shares to these indices, you should
take into account the fact that the Fund's performance reflects the maximum
sales charge of 4.75%, while such charges are not reflected in the performance
of the indices. Returns for the Fund include the reinvestment of any
distribution paid during each period.

The performance information shown represents past performance and is not a
guarantee of future results. The investment return and principal value of your
investment will fluctuate so that your shares, when redeemed, may be worth more
or less than their original cost. Current performance may be lower or higher
than the performance information shown. You may obtain performance information
current to the most recent month-end by calling (800) 862-7919 or visiting
www.riversource.com/investments. Also see "Past Performance" in the Fund's
current prospectus.

22 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


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. At Aug. 31, 2005, the value of foreign securities represented 4.7%
      of net assets.

(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
      Aug. 31, 2005, the value of these securities amounted to $135,734,200 or
      5.5% of net assets.

(e)   The share amount for Limited Liability Companies (LLC) or Limited
      Partnerships (LP) represents capital contributions.

(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 Aug. 31, 2005, the cost of securities purchased, including interest
      purchased, on a when-issued and/or other forward-commitment basis was
      $74,442,316.

(h)   U.S. Treasury inflation-indexed bonds are securities in which the
      principal amount is adjusted for inflation and the semiannual interest
      payments equal a fixed percentage of the inflation-adjusted principal
      amount.

(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 Aug. 31,
      2005.

(j)   Principal only represents securities that entitle holders to receive only
      principal payments on the underlying mortgages. The yield to maturity of a
      principal only is sensitive to the rate of principal payments on the
      underlying mortgage assets. A slow (rapid) rate of principal repayments
      may have an adverse (positive) effect on yield to maturity. Interest rate
      disclosed represents yield based upon the estimated timing of future cash
      flows at Aug. 31, 2005.

(k)   Adjustable rate mortgage; interest rate varies to reflect current market
      conditions; rate shown is the effective rate on Aug. 31, 2005.

(l)   The following abbreviations are used in the portfolio security
      descriptions to identify the insurer of the issue:

      AMBAC   --    Ambac Assurance Corporation

      FGIC    --    Financial Guaranty Insurance Company

      FSA     --    Financial Security Assurance

      MBIA    --    MBIA Insurance Corporation

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

(n)   Comparable securities are held to satisfy future delivery requirements of
      the following open forward sale commitments at Aug. 31, 2005:

      Security                    Principal  Settlement  Proceeds      Value

Notes to Financial Statements

RiverSource Diversified Bond Fund (formerly AXP Diversified Bond Fund)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of AXP Fixed Income Series, Inc. and is registered under
the Investment Company Act of 1940 (as amended) as a diversified, open-end
management investment company. AXP Fixed Income Series, Inc. has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the board. The Fund invests primarily in bonds and other
debt securities including securities issued by the U.S. government, corporate
bonds and mortgage- and asset-backed securities.

The Fund offers Class A, Class B, Class C and Class Y shares.

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

o  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.

o  Class C shares may be subject to a CDSC.

o  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 Aug. 31, 2005, Ameriprise Financial, Inc.
(Ameriprise Financial) (formerly American Express Financial Corporation) owned
100% of Class I shares.

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.
Securities for which market quotations are not readily available are valued at
fair value according to methods selected in good faith by the board. 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.

28 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


Illiquid securities

At Aug. 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 Aug. 31, 2005 was
$3,053,100 representing 0.12% 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.

Securities purchased on a forward-commitment basis

Delivery and payment for securities that have been purchased by the Fund on a
forward-commitment basis, including when-issued securities and other
forward-commitments, can take place one month or more after the transaction
date. During this period, such securities are subject to market fluctuations,
and they may affect the Fund's net assets the same as owned securities. The Fund
designates cash or liquid securities at least equal to the amount of its
forward-commitments. At Aug. 31, 2005, the Fund has entered into outstanding
when-issued securities of $57,643,652 and other forward-commitments of
$16,798,664.

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

Option transactions

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

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

Futures transactions

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

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

Foreign currency translations and foreign currency contracts

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

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.

Forward sale commitments

The Fund may enter into forward sale commitments to hedge its portfolio
positions or to sell mortgage-backed securities it owns under delayed delivery
arrangements. Proceeds of forward sale commitments are not received until the
contractual settlement date. During the time a forward sale commitment is
outstanding, equivalent deliverable securities, or an offsetting forward
purchase commitment deliverable on or before the sale commitment date, are used
to satisfy the commitment.

Unsettled forward sale commitments are valued at the current market value of the
underlying securities, generally according to the procedures described under
"Valuation of securities" above. The forward sale commitment is
"marked-to-market" daily and the change in market value is recorded by the Fund
as an unrealized gain or loss. If the forward sale commitment is closed through
the acquisition of an offsetting purchase commitment, the Fund realizes a gain
or loss. If the Fund delivers securities under the commitment, the Fund realizes
a gain or a loss from the sale of the securities based upon the market price
established at the date the commitment was entered into. Forward sale
commitments outstanding at period end are listed in the "Notes to investments in
securities."

- --------------------------------------------------------------------------------
30 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


Total return swap transactions

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

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

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

Guarantees and indemnifications

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

Federal taxes

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

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been increased by
$4,261,923 and accumulated net realized loss has been increased by $4,261,923.

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 0.52% to 0.395% annually as the Fund's
assets increase.

- --------------------------------------------------------------------------------
32 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


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 0.05% to 0.025% annually
as the Fund's assets increase. Effective Oct. 1, 2005, the fee percentage of the
Fund's average daily net assets declines from 0.07% to 0.04% annually as the
Fund's assets increase. 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:

o  Class A $20.50

o  Class B $21.50

o  Class C $21.00

o  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 were insignificant for the
year ended Aug. 31, 2005 and are included in the transfer agency fees on the
statement of operations.

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
$2,348,664 for Class A, $521,325 for Class B and $4,955 for Class C for the year
ended Aug. 31, 2005.

- --------------------------------------------------------------------------------
33 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


For the year ended Aug. 31, 2005, Ameriprise Financial and its affiliates waived
certain fees and expenses to 0.94% for Class A, 1.70% for Class B, 1.70% for
Class C and 0.78% 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 $1,354,764,
$493,492, $17,606 and $158,983, respectively. In addition, Ameriprise Financial
and its affiliates agreed to extend the current agreement to waive certain fees
and expenses through Sept. 30, 2005. Beginning Oct. 1, 2005, a new agreement to
waive certain fees and expenses is effective until Aug. 31, 2006, such that net
expenses will not exceed 0.89% for Class A, 1.65% for Class B, 1.66% for Class
C, 0.59% for Class I and 0.73% for Class Y of the Fund's average daily net
assets.

During the year ended Aug. 31, 2005, the Fund's custodian and transfer agency
fees were reduced by $117,177 as a result of earnings credits from overnight
cash balances.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $7,427,796,615 and $7,752,415,139, respectively, for the

5. LENDING OF PORTFOLIO SECURITIES

At Aug. 31, 2005, securities valued at $18,115,920 were on loan to brokers. For
collateral, the Fund received $18,330,000 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
$361,192 for the year ended Aug. 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.

8. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
The Bank of New York, 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. 21, 2004. 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 0.50% or the
Prime 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 0.09% per annum. Prior to this
agreement, the Fund had a revolving credit agreement that permitted borrowings
up to $500 million with Deutsche Bank. The Fund had no borrowings outstanding
during the year ended Aug. 31, 2005. Effective Sept. 20, 2005, the Fund entered
into a new revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A., whereby the Fund is permitted to have bank borrowings
for temporary or emergency purposes, including funding shareholder redemptions.

44 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


Fund Expenses Example

(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, 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 Aug. 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

(b)  Based on the actual return for the six months ended Aug. 31, 2005: +2.22%
     for Class A, +1.83% for Class B, +1.83% for Class C, +2.39% for Class I and
     +2.30% 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. Ameriprise Financial and its affiliates
     have contractually agreed to waive certain fees and to absorb certain
     expenses until Aug. 31, 2006, unless sooner terminated at the discretion of
     the Board. Under this expense cap/fee waiver agreement, net expenses will
     not exceed 0.89% for Class A; 1.65% for Class B; 1.66% for Class C; 0.59%
     for Class I; and 0.73% 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 Aug. 31, 2005, the actual
     expenses paid would have been $4.54 for Class A, $8.39 for Class B, $8.44
     for Class C, $3.01 for Class I and $3.72 for Class Y; the hypothetical
     expenses paid would have been $4.53 for Class A, $8.39 for Class B, $8.44
     for Class C, $3.01 for Class I and $3.72 for Class Y.

49 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


Approval of Investment Management Services Agreement

During the period covered by this report, Ameriprise Financial, Inc. (formerly
American Express Financial Corporation or AEFC) (the investment manager), a
wholly-owned subsidiary of American Express Company, served as the investment
manager to the Fund. Under an Investment Management Services Agreement (the
Agreement), the investment manager provides investment advice and other services
to the Fund. Throughout the year, the Funds' Board of Directors and the Board's
Investment Review Committee monitor these services.

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

On February 1, 2005, American Express Company announced its intention to pursue
a spin-off of AEFC by distributing shares of the common stock of AEFC to
shareholders of American Express Company. At a meeting held in person on April
14, 2005, the Board, including a majority of the independent members, approved
the continuation of the Agreement for an interim period, not to exceed one year,
ending on the later of (i) the effective date of the spin-off or (ii) the
approval by the Fund's shareholders of a new investment management services
agreement with the investment manager (the Interim Period). The spin-off will
not result in an "assignment" of the Agreement under the Investment Company Act
of 1940 and, therefore, will not cause the termination of the Agreement
according to its terms. In connection with the spin-off the investment manager
has proposed that going forward, services under the Agreement be provided by an
affiliate, RiverSource Investments, LLC (RiverSource Investments). Independent
counsel advised the Board that it would be prudent, in connection with the
spin-off, to consider a new agreement with RiverSource Investments and to seek
shareholder approval of that agreement as soon as practical thereafter.

Investment performance is a major factor in the evaluation process, and the
Board reviewed the Fund's performance over a range of different periods by
comparing its performance to relevant Lipper and broader market indices. The
Board considered that over time the Fund's investment performance should be
above median for a peer group of funds with similar investment goals and noted
that the Fund's investment performance in 2004 exceeded the median.

The Board noted that, in addition to portfolio management and investment
research, the investment manager provides portfolio trading, daily net asset
value calculation, management of cash flow, product development, administration
of its compliance and legal departments, access to distribution, accounting and
recordkeeping, and reporting to the Board and shareholders. To evaluate these
services, the Board referred to surveys and benchmarks established by commercial
providers, trade associations and the investment manager's internal processes.
The Board concluded that the services provided were consistent with services
provided by investment managers to comparable mutual funds.

- --------------------------------------------------------------------------------
50 -- RIVERSOURCE DIVERSIFIED BOND FUND -- 2005 ANNUAL REPORT


The Board also evaluated the price paid for the services provided by the
investment manager, noting the existence of a pricing philosophy, established by
the Board and the investment manager, that seeks to maintain total Fund expenses
within a range of the median expenses charged to comparable funds sold through
financial advisors. The Board considered detailed information set forth in an
annual report on fees and expenses, including, among other things, data showing
a comparison of the Fund's expenses with median expenses paid by funds in its
comparison group and data showing the Fund's contribution to the investment
manager's profitability. The Board determined that while the Fund's expenses are
higher than the median for its comparison group, the existing fee waiver has
been increased to reduce further the expenses the Fund will pay.

The Board considered the economies of scale that might be realized by the
investment manager as the Fund grew and took note of the extent to which Fund
shareholders also might benefit from such growth. The Board considered that the
Agreement provided for lower fees as assets increase at pre-established
breakpoints and concluded that the Agreement satisfactorily provided for sharing
these economies of scale.

The Board took into account the Contracts Committee's discussion comparing the
fees the investment manager charges to the Fund with those it charges to
institutional clients, noting that the relatively higher fees paid by the Fund
were principally attributable to the additional services required to manage a
regulated mutual fund, like the Fund, and the operation of a large mutual fund
family. The Board also considered the profitability realized by the investment
manager and its affiliates from its relationship with the Fund. The Board took
into account the services acquired by the investment manager through the use of
commission dollars paid by the Fund on portfolio transactions. The Board
concluded that the investment manager's overall costs and profitability were
appropriate, although profitability may be too low on an ongoing basis.

The Board noted that the fees paid by the Fund should permit the investment
manager to offer competitive compensation to its personnel, make necessary
investments in its business and earn an appropriate profit. Based on the
foregoing, the Board concluded that the fees paid to the investment manager
under the Agreement were fair and reasonable and determined to approve renewal
of the Agreement for the Interim Period.

Following the period covered by this report, on September 8, 2005, the Board
approved a new investment management agreement with RiverSource Investments and
recommended its approval by shareholders. The agreement will be considered by
shareholders at a meeting scheduled to be held on February 15, 2006. If
approved, the new agreement would take effect shortly after such approval. The
Board based its approval on, among other factors, its determination that
RiverSource Investments, following the spin-off, would be in a position to
continue to provide the Fund with a level and quality of services that would
meet expectations. The Board also determined that fees to be paid under the new
agreement were fair and reasonable in light of the services to be provided.
