2 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


FUND SNAPSHOT AT FEB. 28, 2007

FUND OVERVIEW

RiverSource Diversified Bond Fund combines securities from all fixed income
sectors including U.S. government bonds, corporate bonds and mortgage-backed
securities. Although the Fund emphasizes high and medium quality bonds, it may
add exposure to high yield bonds and foreign investments in an effort to
achieve higher yield and/or capital appreciation. The Fund targets an
intermediate-term portfolio duration.

SECTOR BREAKDOWN

Percentage of portfolio assets


                                            
Mortgage-Backed                                41.7%
Corporate Bonds(1)                             19.8%
Commercial Mortgage-Backed                     15.9%

      Consumer Discretionary 1.5%, Consumer Staples 1.3%, Health Care 1.3%,
      Energy 1.2%, Industrials 0.4% and Materials 0.3%.

(2)   Of the 5.4%, 2.4% is due to security lending activity and 3.0% is the
      Fund's cash equivalent position.


QUALITY BREAKDOWN

Percentage of bond portfolio assets


                                            
AAA bonds                                      77.6%
AA bonds                                        1.2%
A bonds                                         6.4%         [PIE CHART]
BBB bonds                                      10.6%
Non-investment grade bonds                      4.1%
Non-rated bonds                                 0.1%


Bond ratings apply to underlying holdings of the Fund and not the Fund itself.
Whenever possible, the Standard and Poor's rating is used to determine the
credit quality of a security. Standard and Poor's rates the creditworthiness
of corporate bonds, with 15 categories, ranging from AAA (highest) to D
(lowest). Ratings from AA to CCC may be modified by the addition of a plus (+)
or minus (-) sign to show relative standing within the major rating
categories. Ratings for 0.2% of the bond portfolio assets were determined
through internal analysis.

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

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

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

RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 7


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, the portfolio management team for RiverSource Diversified Bond Fund
discusses the Fund's results and positioning for the six months ended Feb. 28,
2007.

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

A:    RiverSource Diversified Bond Fund's Class A shares (excluding sales
      charge) returned 4.72% for the six months ended Feb. 28, 2007. The Fund
      outperformed its benchmark, the Lehman Brothers Aggregate Bond Index
      (Lehman Index), which gained 3.66%. The Fund also outperformed its peer
      group, as represented by the Lipper Intermediate Investment Grade Index,
      which returned 3.76% during the same period.

      THE FUND OUTPERFORMED ITS BENCHMARK AND PEER GROUP DUE PRIMARILY TO
      ISSUE SELECTION WITHIN COMMERCIAL MORTGAGE-BACKED SECURITIES (CMBS),
      MORTGAGE-BACKED SECURITIES AND INVESTMENT GRADE CORPORATE BONDS.

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

A:    The Fund outperformed its benchmark and peer group due primarily to
      issue selection within commercial mortgage-backed securities (CMBS),
      mortgage-backed securities and investment grade corporate bonds. The
      Fund's exposure to high yield corporate bonds, including bank loans,
      supported the Fund's results as well, as this sector outpaced the Lehman
      Index during the period. The Fund also benefited significantly from the
      payment it received during the period as part of the settlement of the
      WorldCom class action case.

      Interest rates fell in near unison across the yield curve, or range of
      maturities, as the market reacted to mixed economic data releases. Also
      supporting the fixed income market rally was the growing concern that
      weakness in the housing market might spread into the broader economy.
      The Federal Reserve Board (the Fed) kept the targeted federal funds
      rate, an interest rate that affects short-term rates, on hold at 5.25%
      throughout the period. The late-February equity market sell-off saw
      investors shed riskier assets across all markets. All told, the yield on
      the 10-year U.S. Treasury declined approximately 17 basis points (0.17%)
      over the six months, and most other maturity Treasuries fell by a
      similar amount.

8 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS

      Given the declining interest rate environment during the six months, the
      Fund's defensive posture on duration detracted from returns. We
      implemented this duration strategy because in the months after Fed
      policy went on hold, we believed rates declined to levels that appeared
      too low given our view that the economy would slow. Rather than rising
      as we had anticipated, rates continued to fall through the period.
      Duration is a measure of the Fund's sensitivity to interest rate
      changes.

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

A:    We moderately reduced the Fund's sizable position in mortgage-backed
      securities during the period, while maintaining its emphasis on prime
      adjustable rate mortgages (ARMs) and prime agency pass-through
      mortgages. Pass-through mortgages consist of a pool of residential
      mortgage loans, where homeowners' monthly payments of principal,
      interest and prepayments pass from the original bank through a
      government agency or investment bank to investors.

      We modestly increased the Fund's exposure to high yield corporate bonds,
      including bank loans. We expect high yield corporate bonds to perform
      well during the coming months, as we expect that default rates should
      remain low and the demand for yield should remain rather high. We also
      increased the Fund's allocation of investment grade corporate bonds, as
      we viewed the recent volatility within the fixed income sector as a
      buying opportunity. The Fund's portfolio turnover rate for the
      semiannual period was 134%.*

*     A significant portion of the turnover was the result of "roll"
      transactions in the liquid derivatives and Treasury securities. In the
      derivative transactions, positions in expiring contracts are liquidated
      and simultaneously replaced with positions in new contracts with
      equivalent characteristics. In the Treasury transactions, existing
      holdings are sold to purchase newly issued securities with slightly
      longer maturity dates. Although these transactions affect the turnover
      rate of the portfolio, they do not change the risk exposure or result in
      material transactions costs. The remaining turnover resulted from
      strategic reallocations and relative value trading. After transaction
      costs, we expect this activity to enhance the returns on the overall
      Fund.

RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 9


QUESTIONS & ANSWERS

      WE EXPECT HIGH YIELD CORPORATE BONDS TO PERFORM WELL DURING THE COMING
      MONTHS, AS WE EXPECT THAT DEFAULT RATES SHOULD REMAIN LOW AND THE DEMAND
      FOR YIELD SHOULD REMAIN RATHER HIGH.

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

A:    We believe the primary questions facing the fixed income market at the
      end of February centered on the strength of the economy and the
      direction of Fed policy going forward. Until there is more clarity
      surrounding these questions, volatility within the U.S. bond market will
      likely remain high. At the same time, as long as the equity market also
      remains volatile, we believe the heightened risk aversion among
      investors will continue to benefit the higher quality segments of the
      fixed income market. While there are some concerns over whether and how
      the problems in subprime mortgages might impact the broader mortgage
      sector, or indeed the broader economy, for the time being, the problems
      seem largely contained within the subprime mortgage sector, which
      represents only about 15% of the total mortgage securities market.

      Given our view that rates are too low and will ultimately move higher,
      we intend to maintain the Fund's current short duration positioning
      compared to the Lehman Index for the near term. In the non-Treasury
      sectors, we intend to maintain the Fund's significant allocation to CMBS
      and to favor select higher quality industries within the investment
      grade bond sector. We further expect to maintain the Fund's exposure to
      mortgage-backed securities but to stay defensively positioned in ARMs
      and premium coupon securities, which are expected to perform well in a
      rising rate environment. At the end of February, the Fund had no
      exposure to emerging market bonds. As always, we will maintain a
      disciplined focus on individual security selection.

Any specific securities mentioned are for illustrative purposes only and are
not a complete list of securities that have increased or decreased in value.
The views expressed in this statement reflect those of the portfolio

10 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE

(UNAUDITED)

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

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the six months ended Feb. 28, 2007.

ACTUAL EXPENSES

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

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

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

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

(a)   Expenses are equal to the Fund's annualized expense ratio as indicated
      above, multiplied by the average account value over the period,
      multiplied by 181/365 (to reflect the one-half year period).

(b)   Based on the actual return for the six months ended Feb. 28, 2007:
      +4.72% for Class A, +4.34% for Class B, +4.33% for Class C, +4.90% for
      Class I and 4.60% Class R4.

(c)   The actual values and expenses paid are not presented because Class R2,
      Class R3, Class R5 and Class W do not have a full six months of history.
      The inception date of Class R2, Class R3 and Class R5 is Dec. 11, 2006.
      The inception date of Class W is Dec. 1, 2006.

(d)   In September 2006, the Board approved renaming Class Y as Class R4,
      terminating the shareholder servicing agreement, revising the fee
      structure under the transfer agent agreement from an account-based fee
      to an asset-based fee, and adopting a plan administration services
      agreement. In addition, the investment manager and its affiliates have
      contractually agreed to waive certain fees and to absorb certain
      expenses until Aug. 31, 2007, unless sooner terminated at the discretion
      of the Fund's Board, such that net expenses, (excluding fees and
      expenses of acquired funds), will not exceed 0.73% for Class R4. Any
      amounts waived will not be reimbursed by the Fund. These changes were
      effective Dec. 11, 2006. If these changes had been in place for the
      six-month period ended Feb. 28, 2007, the actual and hypothetical
      expenses paid for Class R4 would have been the same as presented in the
      table above.

NOTES TO INVESTMENTS IN SECURITIES (CONTINUED)

(g)   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 Feb. 28,
      2007.

(h)   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 Feb. 28, 2007.

(i)   Interest rate varies either based on a predetermined schedule or to
      reflect current market conditions; rate shown is the effective rate on
      Feb. 28, 2007.

(j)   Adjustable rate mortgage; interest rate varies to reflect current market
      conditions; rate shown is the effective rate on Feb. 28, 2007.

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

38 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Feb. 28, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Diversified Income Series, Inc. and is
registered under the Investment Company Act of 1940 (as amended) as a
diversified, open-end management investment company. RiverSource Diversified
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, Class I and Class R4 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 I and Class R4 shares have no sales charge and are offered only to
      qualifying institutional investors.

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

At Feb. 28, 2007, Ameriprise Financial, Inc. (Ameriprise Financial) and the
affiliated funds-of-funds owned 100% of Class I shares.

Effective Dec. 11, 2006, the Fund offers additional classes of shares, Class
R2, Class R3 and Class R5, offered to certain institutional investors. These
shares are sold without a front-end sales charge or CDSC. At Feb. 28, 2007,
Ameriprise Financial owned 100% of Class R2, Class R3 and Class R5 shares.

Effective Dec. 1, 2006, the Fund offers an additional class of shares, Class
W, offered through qualifying discretionary accounts. Class W shares are sold
without a front-end sales charge or CDSC. At Feb. 28, 2007, Ameriprise
Financial owned 100% of Class W shares.

At Feb. 28, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 12% of the total outstanding Fund shares.


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

RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 39


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

The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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

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.

ILLIQUID SECURITIES

At Feb. 28, 2007, investments in securities included issues that are illiquid
which the Fund currently limits to 10% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at Feb. 28, 2007 was
$6,751,731 representing 0.25% 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 Feb. 28, 2007, the Fund has entered into outstanding
when-issued securities of $85,512,289 and other forward-commitments of
$3,080,000.


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

40 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


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.


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

RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 41


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 Feb. 28, 2007,
foreign currency holdings consisted of European monetary units and British
pounds.

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."

CMBS TOTAL RETURN SWAP TRANSACTIONS

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

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

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

GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

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

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

RECENT ACCOUNTING PRONOUNCEMENTS

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

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

DIVIDENDS TO SHAREHOLDERS

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

OTHER

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

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments,
LLC (the Investment Manager) determines which securities will be purchased,
held or sold. The management fee is a percentage of the Fund's average daily
net assets that declines from 0.48% to 0.29% annually as the Fund's assets
increase.


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

44 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
a fee for administration and accounting services at a percentage of the Fund's
average daily net assets that declines from 0.07% to 0.04% annually as the
Fund's assets increase.

Other expenses in the amount of $12,829 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office
expense, employee compensation, employee health and retirement benefits, and
certain other expenses. Payment of these Fund and Board expenses is
facilitated by a company providing limited administrative services to the Fund
and the Board.

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

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

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

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

o     Class A $20.50

o     Class B $21.50

o     Class C $21.00

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

In addition, with the introduction of Class R2, Class R3, Class R5 and Class W
shares, the Fund will pay the Transfer Agent an annual asset-based fee at a
rate of 0.05% of the Fund's average daily net assets attributable to Class R2,
Class R3 and Class R5 shares and an annual asset-based fee at a rate of 0.20%
of the Fund's average daily net assets attributable to Class W shares.


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

RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 45


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

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

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

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

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

Sales charges received by the Distributor for distributing Fund shares were
$928,404 for Class A, $184,687 for Class B and $1,520 for Class C for the six
months ended Feb. 28, 2007.

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

For the six months ended Feb. 28, 2007, the Investment Manager and its
affiliates waived certain fees and expenses (excluding fees and expenses of
acquired funds), such that net expenses are 0.89% for Class A, 1.65% for Class
B, 1.65% for Class C, 0.54% for Class I, 1.32% for Class R2, 1.07% for Class
R3, 0.73% for Class R4, 0.57% for Class R5 and 0.95% for Class W. Of these
waived fees and expenses, the transfer agency fees waived for Class A, Class
B, Class C, Class R4 and Class W were $620,456, $127,815, $5,195, $37,786 and
$5, respectively, and the management fees waived at the Fund level were
$323,499. In addition, the Investment Manager


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

46 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


and its affiliates have agreed to waive certain fees and expenses until Aug.
31, 2007, unless sooner terminated at the discretion of the Board, such that
net expenses (excluding fees and expenses of acquired funds), will not exceed
0.89% for Class A, 1.65% for Class B, 1.66% for Class C, 0.54% for Class I,
1.32% for Class R2, 1.07% for Class R3, 0.73% for Class R4, 0.57% for Class R5
and 0.97% for Class W of the Fund's average daily net assets.

During the six months ended Feb. 28, 2007, the Fund's custodian and transfer
agency fees were reduced by $120,083 as a result of earnings and bank fee
credits from overnight cash balances.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $3,754,878,291 and $4,075,330,220, respectively, for
the six months ended Feb. 28, 2007. Realized gains and losses are determined
on an identified cost basis.

5. LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend securities
representing up to one-third of the value of its total assets (which includes
collateral for securities on loan) to broker-dealers, banks, or other
institutional borrowers of securities. The Fund receives collateral in the
form of cash and U.S. government securities, equal to at least 100% of the
value of securities loaned, which is marked to the market value of the loaned
securities daily until the securities are returned, e.g., if the value of the
securities on loan increases, additional cash collateral is provided by the
borrower. The Investment Manager serves as securities lending agent for the
Fund under the investment management services agreement pursuant to which the
Fund has agreed to reimburse the Investment Manager for expenses incurred by
it in connection with the lending program, and pursuant to guidelines adopted
by and under the oversight of the Board. At Feb. 28, 2007, securities valued
at $68,423,700 were on loan to brokers. For collateral, the Fund received
$69,055,000 in cash. Cash collateral received is invested in short-term
securities, including U.S. government securities or other high-grade debt
obligations, which are included in the "Investments in securities." Income
from securities lending amounted to $183,803 for the six months ended Feb. 28,
2007. The risks to the Fund of securities lending are that the borrower may
not provide additional collateral when required or return the securities when
due.

6. INTEREST RATE FUTURES CONTRACTS

At Feb. 28, 2007, investments in securities included securities valued at
$1,438,770 that were pledged as collateral to cover initial margin deposits on
1,900 open purchase contracts and 275 open sale contracts. The notional market
value of the open purchase contracts at Feb. 28, 2007 was $207,249,191 with a
net unrealized gain of $1,953,678. The notional market value of the open sale
contracts at Feb. 28, 2007 was $56,362,111 with a net unrealized loss of
$186,527. See "Summary of significant accounting policies" and "Notes to
investments in securities."

7. AFFILIATED MONEY MARKET FUND

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


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

48 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


8. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or
emergency purposes. The agreement went into effect Sept. 19, 2006. The Fund
must maintain asset coverage for borrowings of at least 300%. The agreement,
which enables the Fund to participate with other RiverSource funds, permits
borrowings up to $500 million, collectively. Interest is charged to each Fund
based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund
also pays a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.06% per annum. Prior to this agreement, the
Fund paid a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.07% per annum. The Fund had no borrowings under
the facility outstanding during the six months ended Feb. 28, 2007.

9. FUND MERGER

At the close of business on March 10, 2006, RiverSource Diversified Bond Fund
acquired the assets and assumed the identified liabilities of RiverSource
Selective Fund. The reorganization was completed after shareholders approved
the plan on Feb. 15, 2006.

The aggregate net assets of RiverSource Diversified Bond Fund immediately
before the acquisition were $2,230,540,317 and the combined net assets
immediately after the acquisition were $3,004,582,180.

The merger was accomplished by a tax-free exchange of 91,783,512 shares of
RiverSource Selective Fund valued at $774,041,863.

In exchange for the RiverSource Selective Fund shares and net assets,
RiverSource Diversified Bond Fund issued the following number of shares:



                                                                    SHARES

Class B                                                           17,711,859
Class C                                                              633,369

Class Y                                                            9,182,696



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

RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 49


RiverSource Selective Fund's net assets after adjustments for any permanent
book-to-tax differences at the merger date were as follows, which include the
following amounts of capital stock, unrealized depreciation, accumulated net
realized loss and temporary book-to-tax differences.



                                                                                     TEMPORARY

  Selective Fund   $774,041,863   $826,804,340   $(18,618,938)  $     (34,129,421)  $   (14,118)


10. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$175,789,584 at Aug. 31, 2006, that if not offset by capital gains will expire
as follows:



    2009          2010         2012          2014          2015
                                           
$78,698,873   $49,658,521   $5,227,159   $12,836,807   $29,368,224


RiverSource Diversified Bond Fund acquired $31,763,053 of capital loss
carry-overs in connection with the RiverSource Selective Fund merger (Note 9).
In addition to the acquired capital loss carry-overs, the Fund also acquired
unrealized capital gains as a result of the mergers. The yearly utilization of
the acquired capital losses as well as the utilization of the acquired
unrealized losses is limited by the Internal Revenue Code. It is unlikely the
Board will authorize a distribution of any net realized capital gains until
the available capital loss carry-over has been offset or expires.

11. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

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

50 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT


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

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

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

RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 51


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

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