Although the Fund emphasizes high and medium quality bonds, it may add exposure to high yield bonds and foreign investments in an effort to achieve higher yield and/or capital appreciation. The Fund targets an intermediate-term portfolio duration.

Bond ratings apply to underlying holdings of the Fund and not the Fund itself. Whenever possible, the Standard and Poor's rating is used to determine the credit quality of a security. Standard and Poor's rates the creditworthiness of corporate bonds, with 15 categories, ranging from AAA (highest) to D (lowest). Ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories. Ratings for 0.2% of the bond portfolio assets were determined through internal analysis. There are risks associated with an investment in a bond fund, including credit risk, interest rate risk and prepayment and extension risk. See the Fund's prospectus for information on these and other risks associated with the Fund. In general, bonds prices rise when interest rates fall and vice versa. This effect is usually more pronounced for longer-term securities. Non-investment grade securities, commonly called "high-yield" or "junk" bonds, generally have more volatile prices and carry more risk to principal and income than investment grade securities. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 3 FUND SNAPSHOT AT FEB. 28, 2007 STYLE MATRIX [chart] Shading within the style matrix indicates areas in which the Fund generally invests.

------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 7 QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT Below, the portfolio management team for RiverSource Diversified Bond Fund discusses the Fund's results and positioning for the six months ended Feb. 28, 2007. Q: How did RiverSource Diversified Bond Fund perform for the semiannual period? A: RiverSource Diversified Bond Fund's Class A shares (excluding sales charge) returned 4.72% for the six months ended Feb. 28, 2007. The Fund outperformed its benchmark, the Lehman Brothers Aggregate Bond Index (Lehman Index), which gained 3.66%. The Fund also outperformed its peer group, as represented by the Lipper Intermediate Investment Grade Index, which returned 3.76% during the same period. THE FUND OUTPERFORMED ITS BENCHMARK AND PEER GROUP DUE PRIMARILY TO ISSUE SELECTION WITHIN COMMERCIAL MORTGAGE-BACKED SECURITIES (CMBS), MORTGAGE-BACKED SECURITIES AND INVESTMENT GRADE CORPORATE BONDS. Q: What factors most significantly affected the Fund's performance? A: The Fund outperformed its benchmark and peer group due primarily to issue selection within commercial mortgage-backed securities (CMBS), mortgage-backed securities and investment grade corporate bonds. The Fund's exposure to high yield corporate bonds, including bank loans, supported the Fund's results as well, as this sector outpaced the Lehman Index during the period. The Fund also benefited significantly from the payment it received during the period as part of the settlement of the WorldCom class action case. Interest rates fell in near unison across the yield curve, or range of maturities, as the market reacted to mixed economic data releases. Also supporting the fixed income market rally was the growing concern that weakness in the housing market might spread into the broader economy. The Federal Reserve Board (the Fed) kept the targeted federal funds rate, an interest rate that affects short-term rates, on hold at 5.25% throughout the period. The late-February equity market sell-off saw investors shed riskier assets across all markets. All told, the yield on the 10-year U.S. Treasury declined approximately 17 basis points (0.17%) over the six months, and most other maturity Treasuries fell by a similar amount. ------------------------------------------------------------------------------ 8 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT QUESTIONS & ANSWERS Given the declining interest rate environment during the six months, the Fund's defensive posture on duration detracted from returns. We implemented this duration strategy because in the months after Fed policy went on hold, we believed rates declined to levels that appeared too low given our view that the economy would slow. Rather than rising as we had anticipated, rates continued to fall through the period. Duration is a measure of the Fund's sensitivity to interest rate changes. Q: What changes did you make to the Fund's portfolio during the period? A: We moderately reduced the Fund's sizable position in mortgage-backed securities during the period, while maintaining its emphasis on prime adjustable rate mortgages (ARMs) and prime agency pass-through mortgages. Pass-through mortgages consist of a pool of residential mortgage loans, where homeowners' monthly payments of principal, interest and prepayments pass from the original bank through a government agency or investment bank to investors. We modestly increased the Fund's exposure to high yield corporate bonds, including bank loans. We expect high yield corporate bonds to perform well during the coming months, as we expect that default rates should remain low and the demand for yield should remain rather high. We also increased the Fund's allocation of investment grade corporate bonds, as we viewed the recent volatility within the fixed income sector as a buying opportunity. The Fund's portfolio turnover rate for the semiannual period was 134%.* * A significant portion of the turnover was the result of "roll" transactions in the liquid derivatives and Treasury securities. In the derivative transactions, positions in expiring contracts are liquidated and simultaneously replaced with positions in new contracts with equivalent characteristics. In the Treasury transactions, existing holdings are sold to purchase newly issued securities with slightly longer maturity dates. Although these transactions affect the turnover rate of the portfolio, they do not change the risk exposure or result in material transactions costs. The remaining turnover resulted from strategic reallocations and relative value trading. After transaction costs, we expect this activity to enhance the returns on the overall Fund. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 9 QUESTIONS & ANSWERS WE EXPECT HIGH YIELD CORPORATE BONDS TO PERFORM WELL DURING THE COMING MONTHS, AS WE EXPECT THAT DEFAULT RATES SHOULD REMAIN LOW AND THE DEMAND FOR YIELD SHOULD REMAIN RATHER HIGH. Q: What is the Fund's tactical view and strategy for the months ahead? A: We believe the primary questions facing the fixed income market at the end of February centered on the strength of the economy and the direction of Fed policy going forward. Until there is more clarity surrounding these questions, volatility within the U.S. bond market will likely remain high. At the same time, as long as the equity market also remains volatile, we believe the heightened risk aversion among investors will continue to benefit the higher quality segments of the fixed income market. While there are some concerns over whether and how the problems in subprime mortgages might impact the broader mortgage sector, or indeed the broader economy, for the time being, the problems seem largely contained within the subprime mortgage sector, which represents only about 15% of the total mortgage securities market. Given our view that rates are too low and will ultimately move higher, we intend to maintain the Fund's current short duration positioning compared to the Lehman Index for the near term. In the non-Treasury sectors, we intend to maintain the Fund's significant allocation to CMBS and to favor select higher quality industries within the investment grade bond sector. We further expect to maintain the Fund's exposure to mortgage-backed securities but to stay defensively positioned in ARMs and premium coupon securities, which are expected to perform well in a rising rate environment. At the end of February, the Fund had no exposure to emerging market bonds. As always, we will maintain a disciplined focus on individual security selection. Any specific securities mentioned are for illustrative purposes only and are not a complete list of securities that have increased or decreased in value. The views expressed in this statement reflect those of the portfolio manager(s) only through the end of the period of the report as stated on the cover and do not necessarily represent the views of RiverSource Investments, LLC (RiverSource) or any subadviser to the Fund or any other person in the RiverSource or subadviser organizations. Any such views are subject to change at any time based upon market or other conditions and RiverSource disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a RiverSource Fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any RiverSource Fund. ------------------------------------------------------------------------------ 10 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT FUND EXPENSES EXAMPLE (UNAUDITED) As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments; and (2) ongoing costs, which may include management fees; distribution and service (12b-1) fees; and other Fund fees and expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. In addition to the ongoing expenses which the Fund bears directly, the Fund's shareholders indirectly bear the expenses of the funds in which it invests (also referred to as "acquired funds"), including affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange traded funds). The Fund's indirect expense from investing in the acquired funds is based on the Fund's pro rata portion of the cumulative expenses charged by the acquired funds using the acquired funds expense ratio as of the most recent shareholder report. The example is based on an investment of $1,000 invested at the beginning of the period and held for the six months ended Feb. 28, 2007. ACTUAL EXPENSES The first line of the table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled "Expenses paid during the period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The second line of the table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 11

(c) The actual values and expenses paid are not presented because Class R2, Class R3, Class R5 and Class W do not have a full six months of history. The inception date of Class R2, Class R3 and Class R5 is Dec. 11, 2006. The inception date of Class W is Dec. 1, 2006. (d) In September 2006, the Board approved renaming Class Y as Class R4, terminating the shareholder servicing agreement, revising the fee structure under the transfer agent agreement from an account-based fee to an asset-based fee, and adopting a plan administration services agreement. In addition, the investment manager and its affiliates have contractually agreed to waive certain fees and to absorb certain expenses until Aug. 31, 2007, unless sooner terminated at the discretion of the Fund's Board, such that net expenses, (excluding fees and expenses of acquired funds), will not exceed 0.73% for Class R4. Any amounts waived will not be reimbursed by the Fund. These changes were effective Dec. 11, 2006. If these changes had been in place for the six-month period ended Feb. 28, 2007, the actual and hypothetical expenses paid for Class R4 would have been the same as presented in the table above.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Fund is a series of RiverSource Diversified Income Series, Inc. and is registered under the Investment Company Act of 1940 (as amended) as a diversified, open-end management investment company. RiverSource Diversified Income Series, Inc. has 10 billion authorized shares of capital stock that can be allocated among the separate series as designated by the Board. The Fund invests primarily in bonds and other debt securities including securities issued by the U.S. government, corporate bonds and mortgage- and asset-backed securities. The Fund offers Class A, Class B, Class C, Class I and Class R4 shares. o Class A shares are sold with a front-end sales charge. o Class B shares may be subject to a contingent deferred sales charge (CDSC) and automatically convert to Class A shares during the ninth year of ownership. o Class C shares may be subject to a CDSC. o Class I and Class R4 shares have no sales charge and are offered only to qualifying institutional investors. In September 2006, the Board approved renaming Class Y as Class R4, terminating the shareholder servicing agreement, revising the fee structure under the transfer agent agreement from account-based to asset-based, and adopting a plan administration services agreement. These changes were effective Dec. 11, 2006. At Feb. 28, 2007, Ameriprise Financial, Inc. (Ameriprise Financial) and the affiliated funds-of-funds owned 100% of Class I shares. Effective Dec. 11, 2006, the Fund offers additional classes of shares, Class R2, Class R3 and Class R5, offered to certain institutional investors. These shares are sold without a front-end sales charge or CDSC. At Feb. 28, 2007, Ameriprise Financial owned 100% of Class R2, Class R3 and Class R5 shares. Effective Dec. 1, 2006, the Fund offers an additional class of shares, Class W, offered through qualifying discretionary accounts. Class W shares are sold without a front-end sales charge or CDSC. At Feb. 28, 2007, Ameriprise Financial owned 100% of Class W shares. At Feb. 28, 2007, Ameriprise Financial and the affiliated funds-of-funds owned approximately 12% of the total outstanding Fund shares. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 39 All classes of shares have identical voting, dividend and liquidation rights. Class specific expenses (e.g., distribution and service fees, transfer agency fees, plan administration fees) differ among classes. Income, expenses (other than class specific expenses) and realized and unrealized gains or losses on investments are allocated to each class of shares based upon its relative net assets. The Fund's significant accounting policies are summarized below: USE OF ESTIMATES Preparing financial statements that conform to U.S. generally accepted accounting principles requires management to make estimates (e.g., on assets, liabilities and contingent assets and liabilities) that could differ from actual results. VALUATION OF SECURITIES All securities are valued at the close of each business day. Securities traded on national securities exchanges or included in national market systems are valued at the last quoted sales price. Debt securities are generally traded in the over-the-counter market and are valued at a price that reflects fair value as quoted by dealers in these securities or by an independent pricing service. Securities for which market quotations are not readily available are valued at fair value according to methods selected in good faith by the Board. Short-term securities maturing in more than 60 days from the valuation date are valued at the market price or approximate market value based on current interest rates; those maturing in 60 days or less are valued at amortized cost. ILLIQUID SECURITIES At Feb. 28, 2007, investments in securities included issues that are illiquid which the Fund currently limits to 10% of net assets, at market value, at the time of purchase. The aggregate value of such securities at Feb. 28, 2007 was $6,751,731 representing 0.25% of net assets. These securities are valued at fair value according to methods selected in good faith by the Board. According to board guidelines, certain unregistered securities are determined to be liquid and are not included within the 10% limitation specified above. Assets are liquid if they can be sold or disposed of in the ordinary course of business within seven days at approximately the value at which the asset is valued by the Fund. SECURITIES PURCHASED ON A FORWARD-COMMITMENT BASIS Delivery and payment for securities that have been purchased by the Fund on a forward-commitment basis, including when-issued securities and other forward-commitments, can take place one month or more after the transaction date. During this period, such securities are subject to market fluctuations, and they may affect the Fund's net assets the same as owned securities. The Fund designates cash or liquid securities at least equal to the amount of its forward-commitments. At Feb. 28, 2007, the Fund has entered into outstanding when-issued securities of $85,512,289 and other forward-commitments of $3,080,000. ------------------------------------------------------------------------------ 40 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT The Fund also enters into transactions to sell purchase commitments to third parties at current market values and concurrently acquires other purchase commitments for similar securities at later dates. As an inducement for the Fund to "roll over" its purchase commitments, the Fund receives negotiated amounts in the form of reductions of the purchase price of the commitment. OPTION TRANSACTIONS To produce incremental earnings, protect gains, and facilitate buying and selling of securities for investments, the Fund may buy and write options traded on any U.S. or foreign exchange or in the over-the-counter market where completing the obligation depends upon the credit standing of the other party. The Fund also may buy and sell put and call options and write covered call options on portfolio securities as well as write cash-secured put options. The risk in writing a call option is that the Fund gives up the opportunity for profit if the market price of the security increases. The risk in writing a put option is that the Fund may incur a loss if the market price of the security decreases and the option is exercised. The risk in buying an option is that the Fund pays a premium whether or not the option is exercised. The Fund also has the additional risk of being unable to enter into a closing transaction if a liquid secondary market does not exist. Option contracts are valued daily at the closing prices on their primary exchanges and unrealized appreciation or depreciation is recorded. The Fund will realize a gain or loss when the option transaction expires or closes. When options on debt securities or futures are exercised, the Fund will realize a gain or loss. When other options are exercised, the proceeds on sales for a written call option, the purchase cost for a written put option or the cost of a security for a purchased put or call option is adjusted by the amount of premium received or paid. FUTURES TRANSACTIONS To gain exposure to or protect itself from market changes, the Fund may buy and sell financial futures contracts traded on any U.S. or foreign exchange. The Fund also may buy and write put and call options on these futures contracts. Risks of entering into futures contracts and related options include the possibility of an illiquid market and that a change in the value of the contract or option may not correlate with changes in the value of the underlying securities. Upon entering into a futures contract, the Fund is required to deposit either cash or securities in an amount (initial margin) equal to a certain percentage of the contract value. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily changes in the contract value and are recorded as unrealized gains and losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 41 FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS Securities and other assets and liabilities denominated in foreign currencies are translated daily into U.S. dollars. Foreign currency amounts related to the purchase or sale of securities and income and expenses are translated at the exchange rate on the transaction date. The effect of changes in foreign exchange rates on realized and unrealized security gains or losses is reflected as a component of such gains or losses. In the statement of operations, net realized gains or losses from foreign currency transactions, if any, may arise from sales of foreign currency, closed forward contracts, exchange gains or losses realized between the trade date and settlement date on securities transactions, and other translation gains or losses on dividends, interest income and foreign withholding taxes. At Feb. 28, 2007, foreign currency holdings consisted of European monetary units and British pounds. The Fund may enter into forward foreign currency exchange contracts for operational purposes and to protect against adverse exchange rate fluctuation. The net U.S. dollar value of foreign currency underlying all contractual commitments held by the Fund and the resulting unrealized appreciation or depreciation are determined using foreign currency exchange rates from an independent pricing service. The Fund is subject to the credit risk that the other party will not complete its contract obligations. FORWARD SALE COMMITMENTS The Fund may enter into forward sale commitments to hedge its portfolio positions or to sell mortgage-backed securities it owns under delayed delivery arrangements. Proceeds of forward sale commitments are not received until the contractual settlement date. During the time a forward sale commitment is outstanding, equivalent deliverable securities, or an offsetting forward purchase commitment deliverable on or before the sale commitment date, are used to satisfy the commitment. Unsettled forward sale commitments are valued at the current market value of the underlying securities, generally according to the procedures described under "Valuation of securities" above. The forward sale commitment is "marked-to-market" daily and the change in market value is recorded by the Fund as an unrealized gain or loss. If the forward sale commitment is closed through the acquisition of an offsetting purchase commitment, the Fund realizes a gain or loss. If the Fund delivers securities under the commitment, the Fund realizes a gain or a loss from the sale of the securities based upon the market price established at the date the commitment was entered into. Forward sale commitments outstanding at period end are listed in the "Notes to investments in securities." ------------------------------------------------------------------------------ 42 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT CMBS TOTAL RETURN SWAP TRANSACTIONS The Fund may enter into swap agreements to earn the total return on a specified security or index of fixed income securities. CMBS total return swaps are bilateral financial contracts designed to replicate synthetically the total returns of collateralized mortgage-backed securities. Under the terms of the swaps, the Fund either receives or pays the total return on a reference security or index applied to a notional principal amount. In return, the Fund agrees to pay or receive from the counterparty a floating rate, which is reset periodically based on short-term interest rates, applied to the same notional amount. The notional amounts of swap contracts are not recorded in the financial statements. Swaps are valued daily, and the change in value is recorded as unrealized appreciation (depreciation) until the termination of the swap, at which time realized gain (loss) is recorded. Payments received or made are recorded as realized gains (losses). Swap agreements may be subject to liquidity risk, which exists when a particular swap is difficult to purchase or sell. It may not be possible for the Fund to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. Total return swaps are subject to the risk that the counterparty will default on its obligation to pay net amounts due to the Funds. GUARANTEES AND INDEMNIFICATIONS Under the Fund's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, certain of the Fund's contracts with its service providers contain general indemnification clauses. The Fund's maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined and the Fund has no historical basis for predicting the likelihood of any such claims. FEDERAL TAXES The Fund's policy is to comply with Subchapter M of the Internal Revenue Code that applies to regulated investment companies and to distribute substantially all of its taxable income to shareholders. No provision for income or excise taxes is thus required. Net investment income (loss) and net realized gains (losses) may differ for financial statement and tax purposes primarily because of the deferred losses on certain futures contracts, the recognition of certain foreign currency gains (losses) as ordinary income (loss) for tax purposes and losses deferred due to "wash sale" transactions. The character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. Also, due to the timing of dividend distributions, the fiscal year in which amounts are distributed may differ from the year that the income or realized gains (losses) were recorded by the Fund. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 43 RECENT ACCOUNTING PRONOUNCEMENTS On Sept. 20, 2006, the Financial Accounting Standards Board ("FASB") released Statement of Financial Accounting Standards No. 157 "Fair Value Measurements" ("SFAS 157"). SFAS 157 establishes an authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. The application of SFAS 157 is required for fiscal years beginning after Nov. 15, 2007 and interim periods within those fiscal years. The impact of SFAS 157 on the Fund's financial statements is being evaluated. In June 2006, the Financial Accounting Standards Board (FASB) issued FASB Interpretation 48 (FIN 48), "Accounting for Uncertainty in Income Taxes." FIN 48 clarifies the accounting for uncertainty in income taxes recognized in accordance with FASB Statement 109, "Accounting for Income Taxes." FIN 48 prescribes a two-step process to recognize and measure a tax position taken or expected to be taken in a tax return. The first step is to determine whether a tax position has met the more-likely-than-not recognition threshold and the second step is to measure a tax position that meets the threshold to determine the amount of benefit to recognize. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective for fiscal years beginning after Dec. 15, 2006. Tax positions of the Fund are being evaluated to determine the impact, if any, to the fund. The adoption of FIN 48 is not anticipated to have a material impact on the fund. DIVIDENDS TO SHAREHOLDERS Dividends from net investment income, declared daily and payable monthly, when available, are reinvested in additional shares of the Fund at net asset value or payable in cash. Capital gains, when available, are distributed along with the last income dividend of the calendar year. OTHER Security transactions are accounted for on the date securities are purchased or sold. Dividend income is recognized on the ex-dividend date or upon receipt of ex-dividend notification in the case of certain foreign securities. Interest income, including amortization of premium, market discount and original issue discount using the effective interest method, is accrued daily. 2. EXPENSES AND SALES CHARGES Under an Investment Management Services Agreement, RiverSource Investments, LLC (the Investment Manager) determines which securities will be purchased, held or sold. The management fee is a percentage of the Fund's average daily net assets that declines from 0.48% to 0.29% annually as the Fund's assets increase. ------------------------------------------------------------------------------ 44 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT Under an Administrative Services Agreement, the Fund pays Ameriprise Financial a fee for administration and accounting services at a percentage of the Fund's average daily net assets that declines from 0.07% to 0.04% annually as the Fund's assets increase. Other expenses in the amount of $12,829 are for, among other things, certain expenses of the Fund or the Board including: Fund boardroom and office expense, employee compensation, employee health and retirement benefits, and certain other expenses. Payment of these Fund and Board expenses is facilitated by a company providing limited administrative services to the Fund and the Board. Compensation of Board members includes, for the former Board Chair, compensation as well as retirement benefits. Certain other aspects of the former Board Chair's compensation, including health benefits and payment of certain other expenses, are included under other expenses. Under a Deferred Compensation Plan (the Plan), non-interested board members may defer receipt of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of the Fund or other RiverSource funds. The Fund's liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Plan. Professional fees include fees paid by the Fund for legal services and independent auditor services. Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer Agent) maintains shareholder accounts and records. The Fund pays the Transfer Agent an annual fee per shareholder account for this service as follows: o Class A $20.50 o Class B $21.50 o Class C $21.00 Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as Class R4, the fee structure under the Transfer Agency Agreement was revised from an account-based fee for Class Y to an asset-based fee for Class R4. The Fund will pay the Transfer Agent an annual asset-based fee at a rate of 0.05% of the Fund's average daily net assets attributable to Class R4 shares. Prior to Dec. 11, 2006, the Fund paid the Transfer Agent an annual account-based fee of $18.50 per shareholder account. In addition, with the introduction of Class R2, Class R3, Class R5 and Class W shares, the Fund will pay the Transfer Agent an annual asset-based fee at a rate of 0.05% of the Fund's average daily net assets attributable to Class R2, Class R3 and Class R5 shares and an annual asset-based fee at a rate of 0.20% of the Fund's average daily net assets attributable to Class W shares. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 45 Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate per shareholder account of $1. This amount is included in the transfer agency fee on the statement of operations. Effective Dec. 11, 2006, this fee was eliminated. The Transfer Agent charges an annual closed account fee of $5 per inactive account, charged on a pro rata basis for 12 months from the date the account becomes inactive. These fees are included in the transfer agency fees on the statement of operations. The Fund has agreements with Ameriprise Financial Services, Inc. and RiverSource Distributors, Inc. (collectively, the Distributor) for distribution and shareholder services. Under a Plan and Agreement of Distribution pursuant to Rule 12b-1, the Fund pays a fee at an annual rate of up to 0.25% of the Fund's average daily net assets attributable to Class A, Class R3 and Class W shares, a fee at an annual rate of up to 0.50% of the Fund's average daily net assets attributable to Class R2 shares and a fee at an annual rate of up to 1.00% of the Fund's average daily net assets attributable to Class B and Class C shares. Beginning Dec. 11, 2006, a new Plan Administration Services Agreement was adopted for the restructured Class R4 and the introduction of Class R2 and Class R3. The fee is calculated at a rate of 0.25% of the Fund's average daily net assets attributable to Class R2, Class R3 and Class R4 shares. Prior to Dec. 11, 2006, under a Shareholder Service Agreement, the Fund paid the Distributor a fee for service provided to shareholders by the Distributor and other servicing agents with respect to those shares. The fee was calculated at a rate of 0.10% of the Fund's average daily net assets attributable to Class Y shares. Effective Dec. 11, 2006, this agreement was terminated. Sales charges received by the Distributor for distributing Fund shares were $928,404 for Class A, $184,687 for Class B and $1,520 for Class C for the six months ended Feb. 28, 2007. In addition to the fees and expenses which the Fund bears directly, the Fund indirectly bears a pro rata share of the fees and expenses of the funds in which it invests (also referred to as "acquired funds"), including affiliated and non-affiliated pooled investment vehicles (including mutual funds and exchange traded funds). Because the acquired funds have varied expense and fee levels and the Fund may own different proportions of acquired funds at different times, the amount of fees and expenses incurred indirectly by the Fund will vary. For the six months ended Feb. 28, 2007, the Investment Manager and its affiliates waived certain fees and expenses (excluding fees and expenses of acquired funds), such that net expenses are 0.89% for Class A, 1.65% for Class B, 1.65% for Class C, 0.54% for Class I, 1.32% for Class R2, 1.07% for Class R3, 0.73% for Class R4, 0.57% for Class R5 and 0.95% for Class W. Of these waived fees and expenses, the transfer agency fees waived for Class A, Class B, Class C, Class R4 and Class W were $620,456, $127,815, $5,195, $37,786 and $5, respectively, and the management fees waived at the Fund level were $323,499. In addition, the Investment Manager ------------------------------------------------------------------------------ 46 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT and its affiliates have agreed to waive certain fees and expenses until Aug. 31, 2007, unless sooner terminated at the discretion of the Board, such that net expenses (excluding fees and expenses of acquired funds), will not exceed 0.89% for Class A, 1.65% for Class B, 1.66% for Class C, 0.54% for Class I, 1.32% for Class R2, 1.07% for Class R3, 0.73% for Class R4, 0.57% for Class R5 and 0.97% for Class W of the Fund's average daily net assets. During the six months ended Feb. 28, 2007, the Fund's custodian and transfer agency fees were reduced by $120,083 as a result of earnings and bank fee credits from overnight cash balances. 3. SECURITIES TRANSACTIONS Cost of purchases and proceeds from sales of securities (other than short-term obligations) aggregated $3,754,878,291 and $4,075,330,220, respectively, for the six months ended Feb. 28, 2007. Realized gains and losses are determined on an identified cost basis. 4. CAPITAL SHARE TRANSACTIONS Transactions in shares of capital stock for the periods indicated are as follows:

------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 47 5. LENDING OF PORTFOLIO SECURITIES In order to generate additional income, the Fund may lend securities representing up to one-third of the value of its total assets (which includes collateral for securities on loan) to broker-dealers, banks, or other institutional borrowers of securities. The Fund receives collateral in the form of cash and U.S. government securities, equal to at least 100% of the value of securities loaned, which is marked to the market value of the loaned securities daily until the securities are returned, e.g., if the value of the securities on loan increases, additional cash collateral is provided by the borrower. The Investment Manager serves as securities lending agent for the Fund under the investment management services agreement pursuant to which the Fund has agreed to reimburse the Investment Manager for expenses incurred by it in connection with the lending program, and pursuant to guidelines adopted by and under the oversight of the Board. At Feb. 28, 2007, securities valued at $68,423,700 were on loan to brokers. For collateral, the Fund received $69,055,000 in cash. Cash collateral received is invested in short-term securities, including U.S. government securities or other high-grade debt obligations, which are included in the "Investments in securities." Income from securities lending amounted to $183,803 for the six months ended Feb. 28, 2007. The risks to the Fund of securities lending are that the borrower may not provide additional collateral when required or return the securities when due. 6. INTEREST RATE FUTURES CONTRACTS At Feb. 28, 2007, investments in securities included securities valued at $1,438,770 that were pledged as collateral to cover initial margin deposits on 1,900 open purchase contracts and 275 open sale contracts. The notional market value of the open purchase contracts at Feb. 28, 2007 was $207,249,191 with a net unrealized gain of $1,953,678. The notional market value of the open sale contracts at Feb. 28, 2007 was $56,362,111 with a net unrealized loss of $186,527. See "Summary of significant accounting policies" and "Notes to investments in securities." 7. AFFILIATED MONEY MARKET FUND The Fund may invest its daily cash balance in RiverSource Short-Term Cash Fund, a money market fund established for the exclusive use of the RiverSource funds and other institutional clients of RiverSource Investments. ------------------------------------------------------------------------------ 48 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 8. BANK BORROWINGS The Fund has a revolving credit agreement with a syndicate of banks headed by JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the temporary funding of shareholder redemptions or for other temporary or emergency purposes. The agreement went into effect Sept. 19, 2006. The Fund must maintain asset coverage for borrowings of at least 300%. The agreement, which enables the Fund to participate with other RiverSource funds, permits borrowings up to $500 million, collectively. Interest is charged to each Fund based on its borrowings at a rate equal to either the higher of the Federal Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate. Borrowings are payable within 60 days after such loan is executed. The Fund also pays a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.06% per annum. Prior to this agreement, the Fund paid a commitment fee equal to its pro rata share of the amount of the credit facility at a rate of 0.07% per annum. The Fund had no borrowings under the facility outstanding during the six months ended Feb. 28, 2007. 9. FUND MERGER At the close of business on March 10, 2006, RiverSource Diversified Bond Fund acquired the assets and assumed the identified liabilities of RiverSource Selective Fund. The reorganization was completed after shareholders approved the plan on Feb. 15, 2006. The aggregate net assets of RiverSource Diversified Bond Fund immediately before the acquisition were $2,230,540,317 and the combined net assets immediately after the acquisition were $3,004,582,180. The merger was accomplished by a tax-free exchange of 91,783,512 shares of RiverSource Selective Fund valued at $774,041,863. In exchange for the RiverSource Selective Fund shares and net assets, RiverSource Diversified Bond Fund issued the following number of shares:
SHARES Class A 101,470,543 Class B 17,711,859 Class C 633,369 Class I 33,851,639 Class Y 9,182,696
------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 49 RiverSource Selective Fund's net assets after adjustments for any permanent book-to-tax differences at the merger date were as follows, which include the following amounts of capital stock, unrealized depreciation, accumulated net realized loss and temporary book-to-tax differences.
TEMPORARY TOTAL NET CAPITAL UNREALIZED ACCUMULATED BOOK-TO-TAX ASSETS STOCK DEPRECIATION NET REALIZED LOSS DIFFERENCES ------------------------------------------------------------------------------------------------ RiverSource Selective Fund $774,041,863 $826,804,340 $(18,618,938) $ (34,129,421) $ (14,118)
10. CAPITAL LOSS CARRY-OVER For federal income tax purposes, the Fund had a capital loss carry-over of $175,789,584 at Aug. 31, 2006, that if not offset by capital gains will expire as follows:
2009 2010 2012 2014 2015 $78,698,873 $49,658,521 $5,227,159 $12,836,807 $29,368,224
RiverSource Diversified Bond Fund acquired $31,763,053 of capital loss carry-overs in connection with the RiverSource Selective Fund merger (Note 9). In addition to the acquired capital loss carry-overs, the Fund also acquired unrealized capital gains as a result of the mergers. The yearly utilization of the acquired capital losses as well as the utilization of the acquired unrealized losses is limited by the Internal Revenue Code. It is unlikely the Board will authorize a distribution of any net realized capital gains until the available capital loss carry-over has been offset or expires. 11. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS In June 2004, an action captioned John E. Gallus et al. v. American Express Financial Corp. and American Express Financial Advisors Inc., was filed in the United States District Court for the District of Arizona. The plaintiffs allege that they are investors in several American Express Company mutual funds and they purport to bring the action derivatively on behalf of those funds under the Investment Company Act of 1940. The plaintiffs allege that fees allegedly paid to the defendants by the funds for investment advisory and administrative services are excessive. The plaintiffs seek remedies including restitution and rescission of investment advisory and distribution agreements. The plaintiffs voluntarily agreed to transfer this case to the United States District Court for the District of Minnesota. In response to our motion to dismiss the complaint, the Court dismissed one of plaintiffs' four claims and granted plaintiffs limited discovery. Discovery is currently set to end in March 2007. ------------------------------------------------------------------------------ 50 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT In December 2005, without admitting or denying the allegations, American Express Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc. (Ameriprise Financial)), the parent company of RiverSource Investments, LLC (RiverSource Investments), entered into settlement agreements with the Securities and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC) related to market timing activities. In connection with these matters, the SEC and MDOC issued orders (the Orders) alleging that AEFC violated certain provisions of the federal and Minnesota securities laws by failing to adequately disclose market timing activities by allowing certain identified market timers to continue to market time contrary to disclosures in mutual fund and variable annuity product prospectuses. The Orders also alleged that AEFC failed to implement procedures to detect and prevent market timing in 401(k) plans for employees of AEFC and related companies and failed to adequately disclose that there were no such procedures. Pursuant to the MDOC Order, the MDOC also alleged that AEFC allowed inappropriate market timing to occur by failing to have written policies and procedures and failing to properly supervise its employees. As a result of the Orders, AEFC was censured and ordered to cease and desist from committing or causing any violations of certain provisions of the Investment Advisers Act of 1940, the Investment Company Act of 1940, and various Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to pay disgorgement of $10 million and civil money penalties of $7 million. AEFC also agreed to make presentations at least annually to its board of directors and the relevant mutual funds' board that include an overview of policies and procedures to prevent market timing, material changes to these policies and procedures and whether disclosures related to market timing are consistent with the SEC order and federal securities laws. AEFC also agreed to retain an independent distribution consultant to assist in developing a plan for distribution of all disgorgement and civil penalties ordered by the SEC in accordance with various undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In addition, AEFC agreed to complete and submit to the MDOC a compliance review of its procedures regarding market timing within one year of the MDOC Order, including a summary of actions taken to ensure compliance with applicable laws and regulations and certification by a senior officer regarding compliance and supervisory procedures. Ameriprise Financial and its affiliates have cooperated with the SEC and the MDOC in these legal proceedings, and have made regular reports to the RiverSource Funds' Boards of Directors/Trustees. ------------------------------------------------------------------------------ RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 51 Ameriprise Financial and certain of its affiliates have historically been involved in a number of legal, arbitration and regulatory proceedings, including routine litigation, class actions, and governmental actions, concerning matters arising in connection with the conduct of their business activities. Ameriprise Financial believes that the Funds are not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as necessary, 8-K filings with the Securities and Exchange Commission on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov. There can be no assurance that these matters, or the adverse publicity associated with them, will not result in increased fund redemptions, reduced sale of fund shares or other adverse consequences to the Funds. Further, although we believe proceedings are not likely to have a material adverse effect on the Funds or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Funds, these proceedings are subject to uncertainties and, as such, we are unable to estimate the possible loss or range of loss that may result. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief that could have a material adverse effect on the consolidated financial condition or results of operations of Ameriprise Financial. ------------------------------------------------------------------------------ 52 RIVERSOURCE DIVERSIFIED BOND FUND - 2007 SEMIANNUAL REPORT 12.
