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. - -------------------------------------------------------------------------------- 2 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- (1) The Barclays Capital U.S. Aggregate Bond Index, an unmanaged index, is made up of a representative list of government, corporate, asset-backed and mortgage-backed securities.

LONG X HIGH X MEDIUM QUALITY LOW </Table> 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 - -------------------------------------- Effective duration(2) 3.66 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. - -------------------------------------------------------------------------------- RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT 5 YOUR FUND AT A GLANCE (continued) ---------------------------------------------- PORTFOLIO BREAKDOWN(1) (at Feb. 28, 2010) - --------------------------------------------------------------------- <Table> <Caption> Asset-Backed 8.8% - ------------------------------------------------ Commercial Mortgage-Backed 6.9% - ------------------------------------------------ Consumer Discretionary 2.5% - ------------------------------------------------ Consumer Staples 3.0% - ------------------------------------------------ Energy 2.0% - ------------------------------------------------ Financials 3.7% - ------------------------------------------------ Foreign Government 1.3% - ------------------------------------------------ Health Care 0.7% - ------------------------------------------------ Industrials 1.2% - ------------------------------------------------ Materials 1.1% - ------------------------------------------------ Residential Mortgage-Backed 30.7% - ------------------------------------------------ Telecommunication 5.7% - ------------------------------------------------ U.S. Government Obligations & Agencies 15.2% - ------------------------------------------------ Utilities 9.4% - ------------------------------------------------ Other(2) 7.8% - ------------------------------------------------ </Table> (1) Percentages indicated are based upon total investments (excluding Investments of Cash Collateral Received for Securities on Loan).

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.

(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 FGIC -- Financial Guaranty Insurance Company NPFGC -- National Public Finance Guarantee Corporation XLCA -- XL Capital Assurance </Table> - -------------------------------------------------------------------------------- 34 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- NOTES TO PORTFOLIO OF INVESTMENTS (CONTINUED) (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: <Table> <Caption> ACQUISITION SECURITY DATES COST --------------------------------------------------------------------------- United Artists Theatre Circuit Pass-Through Ctfs 9.30% 2015 02-23-96 thru 08-12-96 $4,235,035 </Table> (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.

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. <Table> <Caption> BARCLAYS CAPITAL (0.11%) SECURITY DESCRIPTION VALUE(a) - ------------------------------------------------------------ Fannie Mae Discount Notes $1,928,595 Federal Farm Credit Bank 753,200 Federal Home Loan Mortgage Corp 3,336,922 Federal National Mortgage Association 1,857,836 - ------------------------------------------------------------ Total market value of collateral securities $7,876,553 - ------------------------------------------------------------ </Table> (t) At Feb. 28, 2010, security was partially or fully on loan.

(v) At Feb. 28, 2010, securities valued at $440,762 were held to cover open call options written. See Note 3 to the financial statements. (w) Pay-in-kind securities are securities in which the issuer makes interest or dividend payments in cash or in additional securities. The securities usually have the same terms as the original holdings. (x) Negligible market value. (y) At Feb. 28, 2010, the cost of securities for federal income tax purposes was approximately $5,866,244,000 and the approximate aggregate gross unrealized appreciation and depreciation based on that cost was: <Table> Unrealized appreciation $149,642,000 Unrealized depreciation (53,551,000) ----------------------------------------------------------- Net unrealized appreciation $96,091,000 ----------------------------------------------------------- </Table> - -------------------------------------------------------------------------------- 36 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- 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.

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. - - Class W shares are offered without a front-end sales charge or CDSC and are offered through qualifying discretionary accounts. At Feb. 28, 2010, RiverSource Investments, LLC (RiverSource Investments or the Investment Manager) and affiliated funds-of-funds in the RiverSource Family of Funds owned 100% of Class I shares. All classes of shares have identical voting, dividend and liquidation rights. Class specific expenses (e.g., distribution and service fees, transfer agency fees, plan administration services fees) differ among classes. Income, expenses (other than class specific expenses) and realized and unrealized gains or losses on investments are allocated to each class of shares based upon its relative net assets. - -------------------------------------------------------------------------------- RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT 55 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- 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. - -------------------------------------------------------------------------------- 62 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- 64 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- FAIR VALUES OF DERIVATIVE INSTRUMENTS AT FEB. 28, 2010 <Table> <Caption> ASSET DERIVATIVES LIABILITY DERIVATIVES ------------------------------ ------------------------------------- STATEMENT OF STATEMENT OF ASSETS ASSETS RISK EXPOSURE AND LIABILITIES AND LIABILITIES CATEGORY LOCATION FAIR VALUE LOCATION FAIR VALUE - ----------------------------------------------------------------------------------------- Foreign exchange Unrealized Unrealized contracts appreciation on depreciation on forward foreign forward foreign currency contracts $334,703 currency contracts $ 1,473,252 - ----------------------------------------------------------------------------------------- Interest rate Net contracts assets -- unreali- zed depreciation N/A N/A on investments 211,571* - ----------------------------------------------------------------------------------------- Interest rate Options contracts contracts N/A N/A written, at value 9,853,574 - ----------------------------------------------------------------------------------------- Total $334,703 $11,538,397 - ----------------------------------------------------------------------------------------- </Table> * Includes cumulative appreciation (depreciation) of futures contracts as reported in the Futures Contracts Outstanding table following the Portfolio of Investments.

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. - -------------------------------------------------------------------------------- RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT 67 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- 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. - -------------------------------------------------------------------------------- 68 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES For the six months ended Feb. 28, 2010, the Investment Manager and its affiliates waived/reimbursed certain fees and expenses such that net expenses (excluding fees and expenses of acquired funds*) were as follows: <Table> Class A.............................................. 0.85% Class B.............................................. 1.61 Class C.............................................. 1.60 Class I.............................................. 0.49 Class R2............................................. 1.29 Class R3............................................. 1.04 Class R4............................................. 0.79 Class R5............................................. 0.54 Class W.............................................. 0.94 </Table> The waived/reimbursed fees and expenses for the transfer agency fees at the class level were as follows: <Table> 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> Class A.............................................. 0.85% Class B.............................................. 1.61 Class C.............................................. 1.60 Class I.............................................. 0.49 Class R2............................................. 1.29 Class R3............................................. 1.04 Class R4............................................. 0.79 Class R5............................................. 0.54 Class W.............................................. 0.94 </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. - -------------------------------------------------------------------------------- RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT 69 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- 5.

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 Contracts and premiums associated with options contracts written during the six months ended Feb. 28, 2010, are as follows: <Table> <Caption> CALLS PUTS ----------------------- ---------------------- CONTRACTS PREMIUMS CONTRACTS PREMIUMS - -------------------------------------------------------------------------- Balance Aug. 31, 2009 -- $ -- -- $ -- Opened 202,775,600 5,888,236 80,001,019 5,588,774 Closed (600) (195,474) (1,019) (336,774) - -------------------------------------------------------------------------- Balance Feb. 28, 2010 202,775,000 $5,692,762 80,000,000 $5,252,000 - -------------------------------------------------------------------------- </Table> - -------------------------------------------------------------------------------- 72 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- 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 $2,047,352,891, respectively, for the six months ended Feb. 28, 2010. The income 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 found in the Portfolio of Investments. 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 - -------------------------------------------------------------------------------- RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT 73 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- 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 At the close of business on Aug. 28, 2009, RiverSource Diversified Bond Fund acquired the assets and assumed the identified liabilities of Seligman Core Fixed Income Fund. The reorganization was completed after shareholders approved the plan on June 2, 2009. The aggregate net assets of RiverSource Diversified Bond Fund immediately before the acquisition were $4,064,386,305 and the combined net assets immediately after the acquisition were $4,074,808,638. The merger was accomplished by a tax-free exchange of 1,510,167 shares of Seligman Core Fixed Income Fund valued at $10,422,333. In exchange for the Seligman Core Fixed Income Fund shares and net assets, RiverSource Diversified Bond Fund issued the following number of shares: <Table> <Caption> SHARES - ------------------------------------------------------------- Class A........................................... 1,176,850 Class B........................................... 284,690 Class C........................................... 643,818 Class R2*......................................... 32,051 Class R5*......................................... 60,341 </Table> * Effective Aug. 29, 2009, Class R and Class I shares were redesignated as Class R2 and Class R5 shares, respectively. The components of Seligman Core Fixed Income Fund's net assets after adjustments for any permanent book-to-tax differences at the merger date were as follows: <Table> <Caption> EXCESS OF DISTRIBUTIONS ACCUMULATED OVER NET TOTAL CAPITAL UNREALIZED NET INVESTMENT NET ASSETS STOCK DEPRECIATION REALIZED LOSS INCOME - ------------------------------------------------------------------------------------------- Seligman Core Fixed Income Fund........ $10,422,333 $12,500,877 $(451,697) $(1,618,941) $(7,906) </Table> 12. FEDERAL TAX INFORMATION Net investment income (loss) and net realized gains (losses) may differ for financial statement and tax purposes primarily because of futures and options contracts, foreign currency contracts, recognition of unrealized appreciation - -------------------------------------------------------------------------------- 74 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- (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 follows: <Table> <Caption> 2010 2012 2013 2014 2017 $49,658,521 $5,227,159 $3,354,885 $10,357,129 $3,705,819 </Table> 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 - -------------------------------------------------------------------------------- 76 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT - -------------------------------------------------------------------------------- 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 - -------------------------------------------------------------------------------- RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT 77 NOTES TO FINANCIAL STATEMENTS (continued) -------------------------------------- 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. - -------------------------------------------------------------------------------- 78 RIVERSOURCE DIVERSIFIED BOND FUND -- 2010 SEMIANNUAL REPORT PROXY VOTING ------------------------------------------------------------------ The policy of the Board is to vote the proxies of the companies in which the Fund holds investments consistent with the procedures as stated in the Statement of Additional Information (SAI).
