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 intermediary,
visiting riversource.com/funds or calling 1(800) 221-2450.

The 4.75% sales charge applicable to Class A shares of the Fund is not reflected
in the table above. If reflected, returns would be lower than those shown. The
performance of other classes may vary from that shown because of differences in
fees and expenses. The Fund's returns reflect the effect of fee waivers/expense
reimbursements, if any. Without such waivers/reimbursements, the Fund's returns
would be lower. See the Average Annual Total Returns table for performance of
other share classes of the Fund.

The indices do not reflect the effects of sales charges, expenses (excluding
Lipper) and taxes. It is not possible to invest directly in an index.

Shading within the style matrix approximates areas in which the Fund is designed
to generally invest.

The style matrix can be a valuable tool for constructing and monitoring your
portfolio. It provides a frame of reference for distinguishing the types of
stocks or bonds owned by a mutual fund, and may serve as a guideline for helping
you build a portfolio.

Investment products, including shares of mutual funds, are not federally or
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.

PORTFOLIO STATISTICS

<Table>
                         
Weighted average life(1)    5.36 years
- --------------------------------------

- --------------------------------------
Weighted average bond
  rating(3)                    AA-/AA3
- --------------------------------------
</Table>





(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 more pronounced for longer-term securities. Non-investment grade securities,
commonly called "high-yield" or "junk" bonds, have more volatile prices and
carry more risk to principal and income than investment grade securities.

Ratings apply to the 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 Investment Manager) rates a security using an
internal rating system when Moody's doesn't provide a rating. Ratings for 0.3%
of the bond portfolio assets were determined through internal analysis.

6  RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 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 ongoing expenses of any funds in which the Fund
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 ongoing expenses charged by
acquired funds using the expense ratio of each of the acquired funds as of the
acquired fund's 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, 2010.

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.

NOTES TO PORTFOLIO OF INVESTMENTS


(a)  Securities are valued by using policies described in Note 2 to the
     financial statements.

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

(c)  Foreign security values are stated in U.S. dollars. For debt securities,
     principal amounts are denominated in U.S. dollar currency unless otherwise
     noted. At Feb. 28, 2010, the value of foreign securities, excluding short-
     term securities, represented 5.55% of net assets.

(d)  Represents a security sold under Rule 144A, which is exempt from
     registration under the Securities Act of 1933, as amended. This security
     may be 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 Feb. 28,
     2010, the value of these securities amounted to $620,191,338 or 14.10% of
     net assets.

(e)  This is a variable rate security that entitles holders to receive only
     interest payments. Interest is paid annually. The interest payment is based
     on the Gross Domestic Product (GDP) level of the previous year for the
     respective country. To the extent that the previous year's GDP exceeds the
     'base case GDP', an interest payment is made equal to 0.012225 of the
     difference.

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

(g)  At Feb. 28, 2010, the cost of securities purchased, including interest
     purchased, on a when-issued and/or other forward-commitment basis was
     $921,696,888. See Note 2 to the financial statements.

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

     <Table>
         
     AGM    -- Assured Guaranty Municipal Corporation
     AMBAC  -- Ambac Assurance Corporation

(i)  Interest only represents securities that entitle holders to receive only
     interest payments on the underlying mortgages. The yield to maturity of an
     interest only security 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. The interest rate disclosed represents yield based
     upon the estimated timing and amount of future cash flows at Feb. 28, 2010.

(j)  Principal only represents securities that entitle holders to receive only
     principal payments on the underlying mortgages. The yield to maturity of a
     principal only is sensitive to the rate of principal payments on the
     underlying mortgage assets. A slow (rapid) rate of principal repayments may
     have an adverse (positive) effect on yield to maturity. Interest rate
     disclosed represents yield based upon the estimated timing of future cash
     flows at Feb. 28, 2010.

(k)  Identifies issues considered to be illiquid as to their marketability (see
     Note 2 to the financial statements). The aggregate value of such securities
     at Feb. 28, 2010 was $4,521,214, representing 0.10% of net assets.
     Information concerning such security holdings at Feb. 28, 2010 is as
     follows:

(l)  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.

(m)  Interest rate varies either based on a predetermined schedule or to reflect
     current market conditions; rate shown is the effective rate on Feb. 28,
     2010.

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

(o)  This position is in bankruptcy.

(p)  Represents comparable securities held to satisfy future delivery
     requirements of the following open forward sale commitments at Feb. 28,

(r)  Represents a senior loan purchased on a when-issued or delayed-delivery
     basis. Certain details associated with this purchase are not known prior to
     the settlement date of the transaction. In addition, senior loans typically
     trade without accrued interest and therefore a weighted average coupon rate
     is not available prior to settlement. At settlement, if still unknown, the
     borrower or counterparty will provide the Fund with the final weighted
     average coupon rate and maturity date.

(s)  The table below represents securities received as collateral subject to
     repurchase agreements. This collateral, which is generally high quality
     short-term obligations, is deposited with the Fund's custodian and,
     pursuant to the terms of the repurchase agreement, must have an aggregate
     market value greater than or equal to the repurchase price plus accrued
     interest at all times. On a daily basis, the market value of securities
     held as collateral for repurchase agreements is monitored to ensure the
     existence of the proper level of collateral.

FAIR VALUE MEASUREMENTS


Generally accepted accounting principles (GAAP) require disclosure regarding the
inputs and valuation techniques used to measure fair value and any changes in
valuation inputs or techniques. In addition, investments shall be disclosed by
major category.

The Fund categorizes its fair value measurements according to a three-level
hierarchy that maximizes the use of observable inputs and minimizes the use of
unobservable inputs by prioritizing that the most observable input be used when
available. Observable inputs are those that market participants would use in
pricing an investment based on market data obtained from sources independent of
the reporting entity. Unobservable inputs are those that reflect the Fund's
assumptions about the information market participants would use in pricing an
investment. An investment's level within the fair value hierarchy is based on
the lowest level of any input that is deemed significant to the asset or
liability's fair value measurement. The input levels are not necessarily an
indication of the risk or liquidity associated with investments at that level.
For example, certain U.S. government securities are generally high quality and
liquid, however, they are reflected as Level 2 because the inputs used to
determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

     - Level 1 -- Valuations based on quoted prices for investments in active
       markets that the Fund has the ability to access at the measurement date.
       Valuation adjustments are not applied to Level 1 investments.

     - Level 2 -- Valuations based on other significant observable inputs
       (including quoted prices for similar securities, interest rates,
       prepayment speeds, credit risks, etc.).

     - Level 3 -- Valuations based on significant unobservable inputs (including
       the Fund's own assumptions and judgment in determining the fair value of
       investments).

Inputs that are used in determining fair value of an investment may include
price information, credit data, volatility statistics, and other factors. These
inputs can be either observable or unobservable. The availability of observable
inputs can vary between investments, and is affected by various factors such as
the type of investment, and the volume and level of activity for that investment
or similar investments in the marketplace. The inputs will be considered by the

Fund Administrator, along with any other relevant factors in the calculation of
an investment's fair value. The Fund uses prices and inputs that are current as
of the measurement date, which may include periods of market dislocations.
During these periods, the availability of prices and inputs may be reduced for
many investments. This condition could cause an investment to be reclassified
between the various levels within the hierarchy.

Investments falling into the Level 3 category are primarily supported by quoted
prices from brokers and dealers participating in the market for those
investments. However, these may be classified as Level 3 investments due to lack
of market transparency and corroboration to support these quoted prices.
Additionally, valuation models may be used as the pricing source for any
remaining investments classified as Level 3. These models rely on one or more
significant unobservable inputs and/or significant assumptions by the Fund
Administrator. Inputs used in a valuation model

FINANCIAL HIGHLIGHTS -----------------------------------------------------------

The following tables are intended to help you understand the Fund's financial
performance. Certain information reflects financial results for a single share
of a class held for the periods shown. For periods ended 2007 and after, per
share net investment income (loss) amounts are calculated based on average
shares outstanding during the period. Total returns assume reinvestment of all
dividends and distributions. Total returns do not reflect payment of sales
charges, if any, and are not annualized for periods of less than one year.

1. ORGANIZATION

RiverSource Diversified Bond Fund (the Fund) is a series of RiverSource
Diversified Income Series, Inc. (the Corporation) and is registered under the
Investment Company Act of 1940, as amended (the 1940 Act) as a diversified,
open-end management investment company. The Corporation has 10 billion
authorized shares of capital stock that can be allocated among the separate
series as designated by the Corporation's Board of Directors (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, Class R2, Class R3, Class
R4, Class R5 and Class W shares.

- -  Class A shares are offered with a front-end sales charge, which may be waived
   under certain circumstances.

- -  Class B shares may be subject to a contingent deferred sales charge (CDSC)
   and automatically convert to Class A shares one month after the completion of
   the eighth year of ownership if originally purchased in a RiverSource fund on
   or after May 21, 2005 or originally purchased in a Seligman fund on or after
   June 13, 2009. Class B shares originally purchased in a RiverSource fund
   prior to May 21, 2005 will convert to Class A shares in the ninth calendar
   year of ownership. Class B shares originally purchased in a Seligman fund
   prior to June 13, 2009 will convert to Class A shares in the month prior to
   the ninth year of ownership.

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

- -  Class I, Class R2, Class R3, Class R4 and Class R5 shares are offered without
   a front-end sales charge or CDSC to qualifying institutional investors.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ADOPTION OF NEW ACCOUNTING STANDARD
In June 2009, the Financial Accounting Standards Board (FASB) established the
FASB Accounting Standards Codification(TM) (Codification) as the single source
of authoritative accounting principles recognized by the FASB in the preparation
of financial statements in conformity with U.S. generally accepted accounting
principles (GAAP). The Codification supersedes existing non-grandfathered, non-
SEC accounting and reporting standards. The Codification did not change GAAP
but, rather, organized it into a hierarchy where all guidance within the
Codification carries an equal level of authority. The Codification became
effective for financial statements issued for interim and annual periods ending
after Sept. 15, 2009. The Codification did not have an effect on the Fund's
financial statements.

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 business of the New York Stock
Exchange (NYSE). Securities traded on national securities exchanges or included
in national market systems are valued at the last quoted sales price from the
primary exchange. Debt securities are generally traded in the over-the-counter
market and are valued by an independent pricing service using an evaluated bid.
When market quotes are not readily available, the pricing service, in
determining fair values of debt securities, takes into consideration such
factors as current quotations by broker/dealers, coupon, maturity, quality, type
of issue, trading characteristics, and other yield and risk factors it deems
relevant in determining valuations. Foreign securities are valued based on
quotations from the principal market in which such securities are normally
traded. The procedures adopted by the Board generally contemplate the use of
fair valuation in the event that price quotations or valuations are not readily
available, price quotations or valuations from other sources are not reflective
of market value and thus deemed unreliable, or a significant event has occurred
in relation to a security or class of securities (such as foreign securities)
that is not reflected in price quotations or valuations from other sources. A
fair value price is a good faith estimate of the value of a security at a given
point in time.

Many securities markets and exchanges outside the U.S. close prior to the close
of the NYSE and therefore the closing prices for securities in such markets or
on

- --------------------------------------------------------------------------------
56  RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT



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



such exchanges may not fully reflect events that occur after such close but
before the close of the NYSE, including significant movements in the U.S. market
after foreign exchanges have closed. Accordingly, in those situations,
Ameriprise Financial, Inc. (Ameriprise Financial), parent company of the
Investment Manager, as administrator to the Fund, will fair value foreign
securities pursuant to procedures adopted by the Board, including utilizing a
third party pricing service to determine these fair values. These procedures
take into account multiple factors, including movements in the U.S. securities
markets, to determine a good faith estimate that reasonably reflects the current
market conditions as of the close of the NYSE. The fair value of a security is
likely to be different from the quoted or published price, if available. Swap
transactions are valued through an authorized pricing service, broker, or an
internal model.

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. Typically, those maturing in 60 days or less that originally had
maturities of more than 60 days at acquisition date are valued at amortized cost
using the market value on the 61st day before maturity. Short-term securities
maturing in 60 days or less at acquisition date are valued at amortized cost.
Amortized cost is an approximation of market value. Investments in money market
funds are valued at net asset value.

FOREIGN CURRENCY TRANSLATIONS
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, 2010 foreign currency holdings were entirely
comprised of Mexican pesos.

REPURCHASE AGREEMENTS
The Fund may enter into repurchase agreements. Generally, securities received as
collateral subject to repurchase agreements are deposited with the Fund's
custodian and, pursuant to the terms of the repurchase agreement, must have an
aggregate market value greater than or equal to the repurchase price plus
accrued interest at all times. On a daily basis, the market value of securities
held as

- --------------------------------------------------------------------------------
                 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT  57



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

collateral for repurchase agreements is monitored to ensure the existence of the
proper level of collateral.

ILLIQUID SECURITIES
At Feb. 28, 2010, investments in securities included issues that are illiquid
which the Fund currently limits to 15% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at Feb. 28, 2010 was
$4,521,214 representing 0.10% of net assets. Certain illiquid securities may be
valued, in good faith, by management at fair value according to procedures
approved by the Board. According to Board guidelines, certain unregistered
securities are determined to be liquid and are not included within the 15%
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, 2010, the Fund has outstanding when-issued securities
of $910,554,342 and other forward-commitments of $11,142,546.

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. The Fund records
the incremental difference between the forward purchase and sale of each forward
roll as realized gain or loss. Losses may arise due to changes in the value of
the securities or if a counterparty does not perform under the terms of the
agreement. If a counterparty files for bankruptcy or becomes insolvent, the
Fund's right to repurchase or sell securities may be limited.

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

- --------------------------------------------------------------------------------
58  RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT



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


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 Portfolio of
Investments.

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 the 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 (which includes net short-term capital gains) to
shareholders. No provision for income or excise taxes is thus required.

Management of the Fund has concluded that there are no significant uncertain tax
positions that would require recognition in the financial statements. Generally,
the tax authorities can examine all tax returns filed for the last three years.

RECENT ACCOUNTING PRONOUNCEMENT
On Jan. 21, 2010, the FASB issued an Accounting Standards Update (the
amendment), Fair Value Measurements and Disclosures (Topic 820): Improving
Disclosures about Fair Value Measurements, which provides guidance on how
investment assets and liabilities are to be valued and disclosed. Specifically,
the amendment requires reporting entities to disclose the input and valuation
techniques used to measure fair value for both recurring and nonrecurring fair
value measurements for Level 2 or Level 3 positions. The amendment also

- --------------------------------------------------------------------------------
                 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT  59



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

requires that transfers between all levels (including Level 1 and Level 2) be
disclosed on a gross basis (i.e., transfers out must be disclosed separately
from transfers in), and the reason(s) for the transfer. Additionally purchases,
sales, issuances and settlements must be disclosed on a gross basis in the Level
3 rollforward. The effective date of the amendment is for interim and annual
periods beginning after Dec. 15, 2009, however, the requirement to provide the
Level 3 activity for purchases, sales, issuances and settlements on a gross
basis will be effective for interim and annual periods beginning after Dec. 15,
2010. At this time the Fund is evaluating the implications of the amendment and
the impact to the financial statements.

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. On Aug. 24, 2009, an additional
dividend was paid before the merger (see Note 10) to ensure that current
shareholders of RiverSource Diversified Bond Fund would not experience a
dilution in their share of the Fund's income or capital gains.

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Dividend income, if any, 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.

3. INVESTMENTS IN DERIVATIVES

The Fund may invest in certain derivative instruments, which are transactions
whose values depend on or are derived from (in whole or in part) the value of
one or more other assets, such as securities, currencies, commodities or
indices. Such derivative instruments may be used to maintain cash reserves while
maintaining exposure to certain other assets, to offset anticipated declines in
values of investments, to facilitate trading, to reduce transaction costs, and
to pursue higher investment returns. The Fund may also use derivative
instruments to mitigate certain investment risks, such as foreign currency
exchange rate risk, interest rate risk, and credit risk. Investments in
derivative instruments may expose the Fund to certain additional risks,
including those detailed below.

FORWARD FOREIGN CURRENCY CONTRACTS
The Fund may enter into forward foreign currency contracts in connection with
settling purchases or sales of securities, to hedge the currency exposure

- --------------------------------------------------------------------------------
60  RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT



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


associated with some or all of the Fund's securities or as part of its
investment strategy. A forward foreign currency contract is an agreement between
two parties to buy and sell a currency at a set price on a future date. The
market value of a forward foreign currency contract fluctuates with changes in
foreign currency exchange rates. Forward foreign currency contracts are marked
to market daily based upon foreign currency exchange rates from an independent
pricing service and the change in value is recorded as unrealized appreciation
or depreciation. The Fund will record a realized gain or loss when the forward
foreign currency contract is closed.

The risks of forward foreign currency contracts include movement in the values
of the foreign currencies relative to the U.S. dollar (or other foreign
currencies) and the possibility that the counterparty will not complete its
contractual obligation, which may be in excess of the amount, reflected in the
Statement of Assets and Liabilities.

FUTURES TRANSACTIONS
The Fund may buy and sell financial futures contracts traded on any U.S. or
foreign exchange to produce incremental earnings, hedge existing positions or
protect against market changes in the value of equities, interest rates or
foreign currencies. The Fund may also buy and write put and call options on
these futures contracts. A futures contract represents a commitment for the
future purchase or sale of an asset at a specified price on a specified date.

Futures and options on futures are valued daily based upon the last sale price
at the close of the market on the principal exchange on which they are traded.
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.

Upon entering into futures contracts, the Fund bears the risk of interest rates,
exchange rates or securities prices moving unexpectedly, in which case, the Fund
may not achieve the anticipated benefits of the futures contracts and may
realize a loss. Additional risks include counterparty credit risk, 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.

OPTION TRANSACTIONS
The Fund may buy and write options traded on any U.S. or foreign exchange, or in
the over-the-counter (OTC) market to produce incremental earnings, protect

- --------------------------------------------------------------------------------
                 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT  61



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------

gains, and facilitate buying and selling of securities for investments. The Fund
may also buy and sell put and call options and write covered call options on
portfolio securities. Options are contracts which entitle the holder to purchase
or sell securities or other financial instruments at a specified price, or in
the case of index options, to receive or pay the difference between the index
value and the strike price of the index option. Completion of transactions for
options traded in the OTC market depends upon the performance of the other
party. Cash collateral may be collected or posted by the Fund to secure certain
OTC options trades. Cash collateral held or posted by the Fund for such option
trades must be returned to the counterparty or the Fund upon closure, exercise
or expiration of the contract.

Option contracts purchased are recorded as investments and options contracts
written are recorded as liabilities of the Fund. Option contracts are valued
daily at the closing prices on their primary exchanges and unrealized
appreciation or depreciation is recorded. Option contracts, including OTC option
contracts, with no readily available market value are valued using quotations
obtained from independent brokers as of the close of the NYSE. The Fund will
realize a gain or loss when the option transaction expires or is exercised. 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.

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.
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 Fund's maximum payout in the case of
written put option contracts represents the maximum potential amount of future
payments (undiscounted) that the Fund could be required to make as a guarantor
for written put options. For OTC options contracts, the transaction is also
subject to counterparty credit risk. The maximum payout amount may be offset by
the subsequent sale, if any, of assets obtained upon the exercise of the put
options by holders of the option contracts or proceeds received upon entering
into the contracts. As of Feb. 28, 2010, the maximum payout amount for written
put options is not readily determinable since any future payments the Fund could
be required to make if the option is exercised are dependent upon future
interest rates which are currently not known.

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


CREDIT DEFAULT SWAP TRANSACTIONS
The Fund may enter into credit default swap transactions to increase or decrease
its credit exposure to an issuer of debt securities, a specific debt security,
or an index of issuers or debt securities. Additionally, credit default swaps
may be used to hedge the Fund's exposure on a debt security that it owns or in
lieu of selling such debt security.

As the purchaser of a credit default swap contract, the Fund purchases
protection by paying a periodic interest rate on the notional amount to the
counterparty. The interest amount is accrued daily as a component of unrealized
appreciation (depreciation) and is recorded as a realized loss upon payment. If
the credit event specified in the contract occurs, the Fund will be required to
deliver either the reference obligation or an equivalent cash amount to the
protection seller and in exchange, the Fund will receive the notional amount
from the seller. The difference between the value of the obligation delivered
and the notional amount received will be recorded as a realized gain (loss). At
Feb. 28, 2010, the Fund had no outstanding credit default swap contracts in
which the Fund was the purchaser of protection.

As the seller of a credit default swap contract, the Fund sells protection to a
buyer and will generally receive a periodic interest rate on the notional
amount. The interest amount is accrued daily as a component of unrealized
appreciation (depreciation) and is recorded as a realized gain upon receipt of
the payment. If the credit event specified in the contract occurs, the Fund will
receive the reference obligation or an equivalent cash amount in exchange for
the payment of the notional amount to the protection buyer. The difference
between the value of the obligation or cash received and the notional amount
paid will be recorded as a realized gain (loss). The maximum potential amount of
undiscounted future payments the Fund could be required to make as the seller of
protection under a credit default swap contract is equal to the notional amount
of the reference obligation. Notional amounts of all credit default swap
contracts outstanding for which the Fund is the seller of protection, if any,
are disclosed in the Credit Default Swap Contracts Outstanding schedule
following the Portfolio of Investments. These potential amounts may be partially
offset by any recovery values of the respective reference obligations or
premiums received upon entering into the agreement.

As a protection seller, the Fund bears the risk of loss from the credit events
specified in the contract. Although specified events are contract specific,
credit events are generally defined as bankruptcy, failure to pay,
restructuring, obligation acceleration, obligation default, or
repudiation/moratorium. For credit default swap contracts on credit indices,
quoted market prices and resulting

- --------------------------------------------------------------------------------
                 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT  63



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


market values serve as an indicator of the current status of the
payment/performance risk. Increasing market values, in absolute terms when
compared to the notional amount of the swap, represent a deterioration of the
reference entity's credit soundness and a greater likelihood or risk of default
or other credit event occurring as defined under the terms of the contract.
Market values for credit default swap contracts in which the Fund is the seller
of protection, if any, are disclosed in the Credit Default Swap Contracts
Outstanding schedule following the Portfolio of Investments. At Feb. 28, 2010,
the Fund had no outstanding credit default swap contracts in which the Fund was
the seller of protection.

The notional amounts and market values of credit default swap contracts are not
recorded in the financial statements. Any premium paid or received by the Fund
upon entering into a credit default swap contract is recorded as an asset or
liability and amortized daily as a component of realized gain (loss) in the
Statement of Operations. Credit default swap contracts are valued daily, and the
change in value is recorded as unrealized appreciation (depreciation) until the
termination of the swap, at which time a realized gain (loss) is recorded.
Credit default swap contracts can involve greater risks than if a fund had
invested in the reference obligation directly since, in addition to general
market risks, credit default swaps are subject to counterparty credit risk,
leverage risk, hedging risk, correlation risk and liquidity risk. The Fund will
enter into credit default swap transactions only with counterparties that meet
certain standards of creditworthiness.

EFFECTS OF DERIVATIVE TRANSACTIONS ON THE FINANCIAL STATEMENTS
The following tables are intended to provide additional information about the
effect of derivatives on the financial statements of the Fund including: the
fair value of derivatives by risk category and the location of those fair values
in the Statement of Assets and Liabilities; the impact of derivative
transactions on the Fund's operations over the period including realized gains
or losses and unrealized gains or losses. The derivative schedules following the
Portfolio of Investments present additional information regarding derivative
instruments outstanding at the end of the period, if any.

4. EXPENSES AND SALES CHARGES

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee

- --------------------------------------------------------------------------------
66  RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT



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


is an annual fee that is equal to a percentage of the Fund's average daily net
assets that declines from 0.48% to 0.29% as the Fund's net assets increase. The
management fee for the six months ended Feb. 28, 2010 was 0.44% of the Fund's
average daily net assets.

ADMINISTRATIVE SERVICES FEES
Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
an annual fee for administration and accounting services equal to a percentage
of the Fund's average daily net assets that declines from 0.07% to 0.04% as the
Fund's net assets increase. The fee for the six months ended Feb. 28, 2010 was
0.06% of the Fund's average daily net assets.

OTHER FEES
Other expenses 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. For the six months ended Feb.
28, 2010, other expenses paid to this company were $17,752.

COMPENSATION OF BOARD MEMBERS
Under a Deferred Compensation Plan (the Plan), the board members who are not
"interested persons" of the Fund under the 1940 Act 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 funds in the RiverSource Family
of Funds. The Fund's liability for these amounts is adjusted for market value
changes and remains in the funds until distributed in accordance with the Plan.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains Fund shareholder accounts and records and provides Fund
shareholder services. The Fund pays the Transfer Agent an annual account-based
fee at a rate equal to $20.50 for Class A, $21.50 for Class B and $21.00 for
Class C for this service. The Transfer Agent also charges an annual fee of $3
per account serviced directly by the Fund or its designated agent for Class A,
Class B and Class C shares. The Fund also pays the Transfer Agent an annual
asset-based fee at a rate of 0.05% of the Fund's average daily net assets
attributable to Class R2, Class R3, Class R4 and Class R5 shares and an annual
asset-based fee at a rate of 0.20% of the Fund's average daily net assets
attributable to Class W shares. The Transfer Agent charges an annual fee of $5
per inactive account, charged on a pro rata basis for the 12 month period from
the date the account becomes inactive. These fees are included in the transfer
agency fees in the Statement of Operations.

In connection with the acquisition of the Seligman Core Fixed Income Fund (see
Note 11), the Fund assumed the obligations of the Seligman Core Fixed Income
Fund, which, together with certain other associated investment companies
(together, the Guarantors), has severally, but not jointly, guaranteed the
performance and observance of all terms and conditions of a lease entered into
by Seligman Data Corp. (SDC), the former transfer agent of the Seligman Core
Fixed Income Fund, including the payment of rent by SDC (the Guaranty). The
lease and the Guaranty expire in January 2019. As of Feb. 28, 2010, the Fund's
total potential future obligation over the life of the Guaranty is $27,163. The
Seligman Core Fixed Income Fund expensed $13,717 related to the Guaranty prior
to acquisition by the Fund. This amount is included within other accrued
expenses in the Fund's Statement of Assets and Liabilities.

PLAN ADMINISTRATION SERVICES FEES
Under a Plan Administration Services Agreement with the Transfer Agent, the Fund
pays an annual fee at a rate of 0.25% of the Fund's average daily net assets
attributable to Class R2, Class R3 and Class R4 shares for the provision of
various administrative, recordkeeping, communication and educational services.

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Fund Distributors, 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 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. For Class B and Class C shares, of
the 1.00% fee, up to 0.75% is reimbursed for distribution expenses.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed (unreimbursed expense) was approximately $7,988,000 and $309,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of Jan. 31, 2010, and may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges, including front-end and CDSCs, received by the Distributor for
distributing Fund shares were $866,070 for Class A, $44,323 for Class B and
$3,069 for Class C for the six months ended Feb. 28, 2010.

(excluding fees and expenses of acquired funds*) were as follows:

<Table>

Class R3.............................................  1.04
Class R4.............................................  0.79
Class R5.............................................  0.54

</Table>


The waived/reimbursed fees and expenses for the transfer agency fees at the

Class A...........................................  $407,869
Class B...........................................    30,139
Class C...........................................     9,922
</Table>


The management fees waived/reimbursed at the Fund level were $721,529.

The Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses until Oct. 31, 2010, unless sooner terminated at the
sole discretion of the Board, such that net expenses (excluding fees and
expenses of acquired funds*) will not exceed the following percentage of the
class' average daily net assets:

<Table>

</Table>


*   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.

7. LENDING OF PORTFOLIO SECURITIES

The Fund has entered into a Master Securities Lending Agreement (the Agreement)
with JPMorgan Chase Bank, National Association (JPMorgan). The Agreement
authorizes JPMorgan as lending agent to lend securities to authorized borrowers
in order to generate additional income on behalf of the Fund. Pursuant to the
Agreement, the securities loaned are secured by cash or U.S. government
securities equal to at least 100% of the market value of the loaned securities.
Any additional collateral required to maintain those levels due to market
fluctuations of the loaned securities is delivered the following business day.
Cash collateral received is invested by the lending agent on behalf of the Fund
into

- --------------------------------------------------------------------------------
                 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT  71



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


authorized investments pursuant to the Agreement. The investments made with the
cash collateral are listed in the Portfolio of Investments. The values of such
investments and any uninvested cash collateral balance are disclosed in the
Statement of Assets and Liabilities along with the related obligation to return
the collateral upon the return of the securities loaned. At Feb. 28, 2010,
securities valued at $657,293,304 were on loan, secured by U.S. government
securities valued at $59,370,217 and by cash collateral of $614,602,086 invested
in short-term securities or in cash equivalents.

Risks of delay in recovery of securities or even loss of rights in the
securities may occur should the borrower of the securities fail financially.
Risks may also arise to the extent that the value of the securities loaned
increases above the value of the collateral received. JPMorgan will indemnify
the Fund from losses resulting from a borrower's failure to return a loaned
security when due. Such indemnification does not extend to losses associated
with declines in the value of cash collateral investments. Loans are subject to
termination by the Fund or the borrower at any time, and are, therefore, not
considered to be illiquid investments.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Income of
$662,595 earned from securities lending for the six months ended Feb. 28, 2010
is included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

8. OPTIONS CONTRACTS WRITTEN

9. 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 funds in the
RiverSource Family of Funds and other institutional clients of RiverSource
Investments. The cost of the Fund's purchases and proceeds from sales of shares
of RiverSource Short-Term Cash Fund aggregated $1,692,289,083 and

distributions received with respect to the Fund's investment in RiverSource
Short-Term Cash Fund can be found in the Statement of Operations and the Fund's
invested balance in RiverSource Short-Term Cash Fund at Feb. 28, 2010, can be

10. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility became effective on Oct.
15, 2009, replacing a prior credit facility. The credit facility agreement,
which is a collective agreement between the Fund and certain other funds in the
RiverSource Family of Funds, severally and not jointly, permits collective
borrowings up to $300 million. The borrowers shall have the right, upon written
notice to the Administrative Agent to request an increase of up to $200 million
in the aggregate amount of the credit facility from new or existing lenders,
provided that the aggregate amount of the credit facility shall at no time
exceed $500 million. Participation in such increase by any existing lender shall
be at such lender's sole discretion. Interest is charged to each Fund based on
its borrowings at a rate equal to the sum of the federal funds rate plus (i)
1.25% per annum plus (ii) if one-month LIBOR exceeds the federal funds rate, the
amount of such excess. Each borrowing under the credit facility matures no later
than 60 days after the date of borrowing. The Fund also pays a commitment fee
equal to its pro rata share of the amount of the credit facility at a rate of
0.10% per annum, in addition to an upfront fee equal to its pro rata share of
0.04% of the amount of the credit facility. Prior to Oct. 15, 2009, the credit
facility agreement, which was a collective agreement between the Fund and
certain other funds in the RiverSource Family of Funds, severally and not
jointly, permitted collective borrowings up to $475 million. Interest was
charged to each Fund based on its borrowings at a rate equal to the federal
funds rate plus 0.75%. The Fund also paid a commitment fee equal to its pro rata
share of the amount of the credit facility at a rate of 0.06% per annum, in
addition to an upfront fee equal to its

pro rata share of 0.02% of the amount of the credit facility. The Fund had no
borrowings during the six months ended Feb. 28, 2010.

11. FUND MERGERS

financial statement and tax purposes primarily because of futures and options
contracts, foreign currency contracts, recognition of unrealized appreciation

(depreciation) for certain derivative investments, post-October losses, market
discount and losses deferred due to wash sales. 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.

For federal income tax purposes, the Fund had a capital loss carry-over of
$72,303,513 at Aug. 31, 2009 that if not offset by capital gains will expire as

Because the measurement periods for a regulated investment company's income are
different for excise tax purposes versus income tax purposes, special rules are
in place to protect the amount of earnings and profits needed to support excise
tax distributions. As a result, the Fund is permitted to treat net capital
losses realized between Nov. 1, 2008 and its fiscal year end (post-October loss)
as occurring on the first day of the following tax year. At Aug. 31, 2009, the
Fund had a post-October loss of $176,242,993 that is treated for income tax
purposes as occurring on Sept. 1, 2009.

It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires. There is no assurance that the Fund will be able to utilize all of its
capital loss carry-over before it expires.

13. SUBSEQUENT EVENTS

Management has evaluated Fund related events and transactions that occurred
during the period from the date of the Statement of Assets and Liabilities
through the date of issuance of the Fund's financial statements. There were no
events or transactions that occurred during the period that materially impacted
the amounts or disclosures in the Fund's financial statements.

14. 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 (now known as

- --------------------------------------------------------------------------------
                 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT  75



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


RiverSource) mutual funds and they purport to bring the action derivatively on
behalf of those funds under the Investment Company Act of 1940. The plaintiffs
allege that fees allegedly paid to the defendants by the funds for investment
advisory and administrative services are excessive. The plaintiffs seek remedies
including restitution and rescission of investment advisory and distribution
agreements. The plaintiffs voluntarily agreed to transfer this case to the
United States District Court for the District of Minnesota (the District Court).
In response to defendants' motion to dismiss the complaint, the District Court
dismissed one of plaintiffs' four claims and granted plaintiffs limited
discovery. Defendants moved for summary judgment in April 2007. Summary judgment
was granted in the defendants' favor on July 9, 2007. The plaintiffs filed a
notice of appeal with the Eighth Circuit Court of Appeals (the Eighth Circuit)
on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary
judgment and remanded to the District Court for further proceedings. On August
6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court,
asking the U.S. Supreme Court to stay the District Court proceedings while the
U.S. Supreme Court considers and rules in a case captioned Jones v. Harris
Associates, which involves issues of law similar to those presented in the
Gallus case.

In December 2005, without admitting or denying the allegations, American Express
Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc.
(Ameriprise Financial)), entered into settlement agreements with the Securities
and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC)
related to market timing activities. As a result, 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. AEFC agreed to pay disgorgement of $10 million
and civil money penalties of $7 million. 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. 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.

On November 7, 2008, RiverSource Investments, LLC, a subsidiary of Ameriprise
Financial, Inc., acquired J. & W. Seligman & Co. Incorporated (Seligman). In
late 2003, Seligman conducted an extensive internal review concerning mutual
fund trading practices. Seligman's review, which covered the period 2001-2003,
noted one arrangement that permitted frequent trading in

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

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



certain open-end registered investment companies managed by Seligman (the
Seligman Funds); this arrangement was in the process of being closed down by
Seligman before September 2003. Seligman identified three other arrangements
that permitted frequent trading, all of which had been terminated by September
2002. In January 2004, Seligman, on a voluntary basis, publicly disclosed these
four arrangements to its clients and to shareholders of the Seligman Funds.
Seligman also provided information concerning mutual fund trading practices to
the SEC and the Office of the Attorney General of the State of New York (NYAG).

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc. (now known as RiverSource Fund
Distributors), Seligman Data Corp. and Brian T. Zino (collectively, the Seligman
Parties), alleging, in substance, that the Seligman Parties permitted various
persons to engage in frequent trading and, as a result, the prospectus
disclosure used by the registered investment companies then managed by Seligman
was and had been misleading. The NYAG included other related claims and also
claimed that the fees charged by Seligman to the Seligman Funds were excessive.
On March 13, 2009, without admitting or denying any violations of law or
wrongdoing, the Seligman Parties entered into a stipulation of settlement with
the NYAG and settled the claims made by the NYAG. Under the terms of the
settlement, Seligman paid $11.3 million to four Seligman Funds. This settlement
resolved all outstanding matters between the Seligman Parties and the NYAG. In
addition to the foregoing matter, the New York staff of the SEC indicated in
September 2005 that it was considering recommending to the Commissioners of the
SEC the instituting of a formal action against Seligman and Seligman Advisors,
Inc. relating to frequent trading in the Seligman Funds. Seligman responded to
the staff in October 2005 that it believed that any action would be both
inappropriate and unnecessary, especially in light of the fact that Seligman had
previously resolved the underlying issue with the Independent Directors of the
Seligman Funds and made recompense to the affected Seligman Funds. There have
been no further developments with the SEC on this matter.

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.
