2   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT


FUND SNAPSHOT AT AUG. 31, 2006

- ------------------------------------------------------------------------------
FUND OVERVIEW
- ------------------------------------------------------------------------------

RiverSource Diversified Bond Fund combines securities from all fixed income
sectors including U.S. government, corporate, and mortgage-backed securities.
Although the Fund emphasizes high and medium quality bonds, it
opportunistically adds exposure to high yield and emerging markets. The Fund's
intermediate-term portfolio is less volatile when interest rates fluctuate.
The multisector structure of the Fund provides a one-stop investment
opportunity for fixed income investors.

Bond ratings apply to underlying holdings of the Fund and not the Fund itself.
Whenever possible, the Standard and Poor's rating is used to determine the
credit quality of a security. Standard and Poor's rates the creditworthiness
of corporate bonds, with 15 categories, ranging from AAA (highest) to D
(lowest). Ratings from AA to CCC may be modified by the addition of a plus (+)
or minus (-) sign to show relative standing within the major rating
categories. If Standard and Poor's doesn't rate a security, then Moody's
rating is used. RiverSource Investments, LLC, the Fund's investment manager,
rates a security using an internal rating system when Moody's doesn't provide
a rating. 0.2% of the portfolio rating above was determined through internal
analysis.

(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.


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

6   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, the portfolio management team for RiverSource Diversified Bond Fund
discusses the Fund's results and positioning for the 12 months ended Aug. 31,
2006. On March 10, 2006, the assets of RiverSource Selective Fund were merged
into RiverSource Diversified Bond Fund. This reorganization was completed
after shareholders of RiverSource Selective Fund approved the merger plan on
Feb. 15, 2006.

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

A:    RiverSource Diversified Bond Fund's Class A shares (excluding sales
      charge) returned 1.64% for the 12 months ended Aug. 31, 2006. The Fund
      underperformed its benchmark, the unmanaged Lehman Brothers Aggregate
      Bond Index (Lehman Index), which gained 1.71%. The Fund outperformed its
      peer group, as represented by the Lipper Intermediate Investment Grade
      Index, which returned 1.62% during the same period.

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

A:    Increases in short-term interest rates had the greatest impact on the
      Fund. Short-term interest rates were forced higher by the Federal
      Reserve Board (the Fed), which raised its target for the federal funds
      rate, an interest rate that affects short-term rates, to 5.25% from
      3.50%. In early August, the Fed observed its first pause in its two-year
      tightening cycle, noting that economic growth appeared to be moderating
      somewhat and inflation pressures -- though elevated -- were expected to
      recede over the balance of the year and into 2007. As a result of this
      Fed pause, rates declined during August in a sharp reversal of what had
      been a steady rise in interest rates. Thus, most of the Fund's returns
      were achieved during this last month of the fiscal year.

      Given the rising interest rate environment throughout the majority of
      the fiscal year, we maintained a defensive posture on duration, which
      helped mitigate the Fund's interest rate risk. Duration is a measure of
      the Fund's sensitivity to interest rate changes. Also, while interest
      rates moved higher across the fixed income yield curve during most of
      the annual period, they did so significantly more so at the short-term
      end of the curve than at the long-term end. This resulted in a continued
      flattening of the yield curve. The Fund also benefited during much of
      the period from its moderate exposure to bonds with shorter maturities
      in favor of those with longer maturities, i.e., its yield curve
      flattening bias.

RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT   7


QUESTIONS & ANSWERS

      Also helping the Fund's results was its issue selection within the
      mortgage-backed securities sector of the fixed income market. The Fund's
      defensive positioning in higher coupon mortgages, adjustable rate
      mortgages (ARMs) and collateralized mortgage obligations (CMOs) helped
      results, as these securities outperformed Treasuries during the 12
      months ended Aug. 31, 2006.

- ------------------------------------------------------------------------------
      GIVEN THE RISING INTEREST RATE ENVIRONMENT THROUGHOUT THE MAJORITY OF
      THE FISCAL YEAR, WE MAINTAINED A DEFENSIVE POSTURE ON DURATION, WHICH
      HELPED MITIGATE THE FUND'S INTEREST RATE RISK.

      Also contributing positively to the Fund's performance during the annual
      period was its positioning in non-U.S. dollar bonds, or bonds
      denominated in foreign currencies. The U.S. dollar weakened vs. most
      major international currencies, including the euro and the British
      pound, during the fiscal year, increasing the value of the Fund's
      non-U.S. dollar bonds in U.S. dollar terms. Remember, a weakening U.S.
      dollar increases the value of the Fund's foreign currency denominated
      securities when expressed in U.S. dollar terms and vice versa.

      Finally, an allocation to high yield corporate bonds further boosted the
      Fund's returns, as high yield corporate bonds were among the
      best-performing fixed income sectors during the period.

      Conversely, detracting from the Fund's returns was its comparatively
      greater emphasis on higher quality investments than its benchmarks.
      While the portfolio's securities performed well, they did not keep pace
      with even stronger performance by the riskier segments of the market,
      and so the Fund's performance lagged relative to the Lehman Index.

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

A:    We maintained a shorter duration position than the Lehman Index for most
      of the annual period. However, by May, once 10-year Treasury yields
      breached the 5% level and we began to anticipate the Fed nearing an end
      to its tightening cycle, we moved toward a neutral duration position
      relative to the Lehman Index.

8   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT


QUESTIONS & ANSWERS

      We increased the Fund's already sizable allocation to mortgage-backed
      securities by reducing its exposure to agencies and investment-grade
      corporate bonds. In June, we initiated a yield curve steepening bias by
      selling longer-maturity bonds in favor of two-year Treasuries, in an
      effort to take advantage of our expectation that long-term rates will
      rise more than short-term rates over the coming months. The Fund's
      portfolio turnover rate for the annual period was 281%.*

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

A:    U.S. interest rates across the range of maturities, or yield curve, have
      declined to levels that appear too low given our view that the economy
      may slow modestly. We would characterize the slowing economy as a "soft
      landing" and we think inflation may be nudged higher over the remainder
      of 2006. Thus, we believe the Fed is likely to pause with its targeted
      federal funds rate at its current 5.25% for an extended period of time.

      Based on this view, we intend to maintain the Fund's duration only
      modestly shorter than the Lehman Index for the near term and we continue
      to favor shorter maturity notes over longer maturity bonds. We intend to
      maintain the Fund's modest exposure to investment-grade corporate bonds
      and its more significant allocations to mortgage-backed securities,
      commercial mortgage-backed securities and asset-backed securities.
      Mortgages remain an attractive source of yield, given our views that
      interest rates will likely be rather range-bound during the next several
      months. However, the strong performance of mortgages toward the end of
      the annual period will likely lead us to moderately reduce the Fund's
      still significant allocation to the sector. As always, we will maintain
      a disciplined focus on individual security selection.

*     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 transaction 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.

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 9/1/96 to
8/31/06) 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

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

(b)   Interest rate varies either based on a predetermined schedule or to
      reflect current market conditions; rate shown is the effective rate on
      Aug. 31, 2006.

(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, 2006, the value of foreign securities
      represented 2.7% of net assets.

      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, 2006, the value of these securities
      amounted to $127,759,051 or 4.4% of net assets.

(e)   At Aug. 31, 2006, the cost of securities purchased, including interest

      in, or are secured by and payable from, mortgage loans secured by real

      adjusted for inflation and the semiannual interest payments equal a
      fixed percentage of the inflation-adjusted principal amount.

      was $3,213,698,280 and the aggregate gross unrealized appreciation and
      depreciation based on that cost was:

32   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Diversified Income Series, Inc. (formerly
RiverSource Fixed 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 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, 2006, Ameriprise Financial, Inc.
(Ameriprise Financial) and the affiliated funds-of-funds owned 100% of Class I
shares, which represents 9.57% of the Fund's net assets.

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

The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

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


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

RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT   33


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 Aug. 31, 2006, 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, 2006 was
$7,405,517 representing 0.26% 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, 2006, the Fund has entered into outstanding
when-issued securities of $262,504,597 and other forward-commitments of
$12,050,642.

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


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

34   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT


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. At Aug. 31, 2006,
foreign currency holdings consisted of European monetary units and British
pounds.


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

RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT   35


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).


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

36   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT


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.

On the statement of assets and liabilities, as a result of permanent
book-to-tax differences, undistributed net investment income has been
increased by $189,392 and accumulated net realized loss has been increased by
$96,262 resulting in a net reclassification adjustment to decrease paid-in
capital by $93,130.

RECENT ACCOUNTING PRONOUNCEMENTS

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, that will result from the adoption of FIN 48.

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. 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 0.48% to 0.29% annually as
the Fund's assets increase. Prior to March 1, 2006, the fee percentage of the
Fund's average daily net assets declined from 0.52% to 0.395% annually as the
Fund's assets increased.

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 0.07% to 0.04% annually
as the Fund's assets increase. Prior to Oct. 1, 2005, the fee percentage of
the Fund's average daily net assets declined from 0.05% to 0.025% annually as
the Fund's assets increased. A minor portion of additional administrative
service expenses paid by the Fund are consultants' fees and fund office
expenses. Under this agreement, the Fund also pays taxes, audit and certain
legal fees, registration fees for shares, compensation of board members,
corporate filing fees and any other expenses properly payable by the Fund and
approved by the Board.

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


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

RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT   39


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

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.

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. (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 the Distributor and other servicing agents
with respect to those shares. The fee is calculated at a rate of 0.10% of the
Fund's average daily net assets attributable to Class Y shares.

Sales charges received by the Distributor for distributing Fund shares were
$2,083,362 for Class A, $670,839 for Class B and $3,787 for Class C for the
year ended Aug. 31, 2006.

For the year ended Aug. 31, 2006, the Investment Manager and its affiliates
waived certain fees and expenses to 0.89% for Class A, 1.65% for Class B,
1.66% for Class C, 0.54% for Class I and 0.73% 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 $1,609,229, $435,882, $15,500 and $111,791, respectively
and the management fees waived at the Fund level were $270,688. Under this
agreement, which was effective until Feb. 28, 2006, net expenses would 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.
Effective as of March 1, 2006, the Investment Manager 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 will not
exceed 0.89% for Class A, 1.65% for Class B, 1.66% for Class C, 0.54% for
Class I and 0.73% for Class Y of the Fund's average daily net assets.

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. 20, 2005. The Fund

which enables the Fund to participate with other RiverSource funds, permits
borrowings up to $500 million, collectively. Interest is charged to each Fund
based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund
also pays a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.07% per annum. Prior to this agreement, the
Fund had a revolving credit agreement that permitted borrowings up to $500
million with The Bank of New York. The Fund had no borrowings outstanding

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

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


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 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.

44   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 ANNUAL REPORT


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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD AND SHAREHOLDERS
RIVERSOURCE DIVERSIFIED INCOME SERIES, INC.

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments in securities, of RiverSource
Diversified Bond Fund (a series of RiverSource Diversified Income Series,
Inc.) as of August 31, 2006, the related statement of operations for the year
then ended, the statements of changes in net assets for each of the years in
the two-year period ended August 31, 2006, and the financial highlights for
each of the years in the five-year period ended August 31, 2006. These
financial statements and the financial highlights are the responsibility of
fund management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and the financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. Our
procedures included confirmation of securities owned as of August 31, 2006, by
correspondence with the custodian and brokers or by other appropriate auditing
procedures. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
RiverSource Diversified Bond Fund as of August 31, 2006, and the results of
its operations, changes in its net assets and the financial highlights for
each of the periods stated in the first paragraph above, in conformity with
U.S. generally accepted accounting principles.

54   RIVERSOURCE DIVERSIFIED BOND FUND - 2006 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, 2006.

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.
