(a) The Investment Manager and its affiliates have contractually agreed to waive certain fees and to absorb certain expenses until May 31, 2009, unless sooner terminated at the discretion of the Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under this agreement, net fund expenses (excluding fees and expenses of acquired funds), will not exceed 1.02% for Class A, 1.78% for Class B, 1.77% for Class C, 0.65% for Class I, 1.45% for Class R2, 1.20% for Class R3, 0.95% for Class R4, 0.70% for Class R5 and 1.10% for Class W. (1) WEIGHTED AVERAGE LIFE measures a bond's maturity, which takes into consideration the possibility that the issuer may call the bond before its maturity date. (2) EFFECTIVE DURATION measures the sensitivity of a security's price to parallel shifts in the yield curve (the graphical depiction of the levels of interest rates from two years out to 30 years). Positive duration means that as rates rise, the price decreases, and negative duration means that as rates rise, the price increases. (3) WEIGHTED AVERAGE BOND RATING represents the average credit quality of the underlying bonds in the portfolio. There are risks associated with an investment in a bond fund, including credit risk, interest rate risk, and prepayment and extension risk. See the Fund's prospectus for information on these and other risks associated with the Fund. In general, bond prices rise when interest rates fall and vice versa. This effect is usually more pronounced for longer-term securities. Non-investment grade securities, commonly called "high-yield" or "junk" bonds, generally have more volatile prices and carry more risk to principal and income than investment grade securities. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 3 YOUR FUND AT A GLANCE (continued) ---------------------------------------------- AVERAGE ANNUAL TOTAL RETURNS --------------------------------------------------------------------------------

The Fund underperformed its benchmark, the JP Morgan Global High Yield Index (JP Morgan Index), which fell 1.00% during the same period. The Fund also underperformed the Lipper High Current Yield Bond Funds Index, representing the Fund's peer group, which declined 2.13% during the same time frame. SIGNIFICANT PERFORMANCE FACTORS The high yield corporate bond market experienced more ups and downs during the annual period than at any other time in recent memory. The high yield market had rallied strongly going into the annual period, with spreads, or the yield differential between these securities and Treasuries, reaching an all-time low level in May 2007. During June and July 2007, problems in the subprime mortgage market spilled over into most other credit markets in general, and into the high yield corporate bond market in particular. High yield corporate bonds traded down sharply, as investors grew increasingly risk averse and spreads widened. In August, the high yield bond market stabilized somewhat, and from September through most SECTOR DIVERSIFICATION(1) (at May 31, 2008; % of portfolio assets) ----------------------------------------------------------------- Consumer Discretionary 16.4% -------------------------------------------------------------- Consumer Staples 6.9% -------------------------------------------------------------- Energy 11.4% -------------------------------------------------------------- Financials 3.9% -------------------------------------------------------------- Health Care 10.6% -------------------------------------------------------------- Industrials 5.0% -------------------------------------------------------------- Materials 11.4% -------------------------------------------------------------- Mortgage-Backed 0.4% -------------------------------------------------------------- Telecommunication 25.2% -------------------------------------------------------------- Utilities 6.9% -------------------------------------------------------------- Other(2) 1.9% --------------------------------------------------------------

Then, a second wave of concern hit the market amid a liquidity crunch, recession worries and ongoing turmoil in the housing, subprime mortgage and credit markets. Large investment banks took major credit-related write-downs and the highly leveraged structured product market remained somewhat dysfunctional. Thus, November through March proved to be another difficult span for the high yield bond market, with spreads widening once again. The high yield bank loan sector performed particularly poorly in January and February, hit by the combination of growing credit concerns, the liquidity crunch and an overhang of supply with dried-up demand. All of this turmoil culminated in mid-March when the Federal Reserve Board (the Fed) orchestrated a buyout of Bear Stearns, which was on the verge of collapsing, by JPMorgan Chase. The Fed's actions stabilized the markets somewhat in the last months of the annual period by demonstrating that the Fed would do whatever was necessary to quiet fears and prevent systemic failure. In April, the high yield corporate bond market bounced back somewhat, with spreads tightening. The high yield corporate bond market exhibited relative stability during May. The Fund's overweight positioning in the health care sector relative to the JP Morgan Index helped the Fund's results most, as this defensive sector proved to be less volatile than others in the high yield bond market. The bonds of hospital companies IASIS HEALTHCARE, HCA and COMMUNITY HEALTH SYSTEMS performed particularly well. The Fund also benefited from its overweight exposure to the QUALITY BREAKDOWN (at May 31, 2008; % of portfolio assets excluding cash equivalents and equities) ----------------------------------------------------------------- AAA bonds 0.4% -------------------------------------------------------------- BBB bonds 1.9% -------------------------------------------------------------- BB bonds 33.4% -------------------------------------------------------------- B bonds 49.2% -------------------------------------------------------------- CCC bonds 14.4% -------------------------------------------------------------- Non-rated bonds 0.7% --------------------------------------------------------------
Bond 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 Fund's investment manager, rates a security using an internal rating system when Moody's doesn't provide a rating. Ratings for 0.9% of the bond portfolio assets were determined through internal analysis. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 7 MANAGER COMMENTARY (continued) ------------------------------------------------- energy sector. Here, holdings in energy infrastructure company DRESSER, INC. and exploration and production company SANDRIDGE ENERGY boosted results. In industrials, aluminum producer NORANDA ALUMINUM was an outstanding performer given rising commodity prices during the annual period. The Fund's underweight position in the automotive industry also contributed positively to performance, as this industry fared poorly during the period. Conversely, retailer CLAIRE'S STORES, which had conducted a leveraged buyout in early 2007, performed poorly and detracted from the Fund's results. We sold the Fund's position in this issue during the second half of the fiscal year. Similarly, holding a position in REALOGY, the parent company of Century 21, ERA, Coldwell Banker and Sotheby's Intl Realty, detracted from the Fund's performance. REALOGY, which had completed a leveraged buyout in the spring of 2007, got swept by the brush of the massive slowdown in the housing market and concerns over housing depreciation. We maintained the Fund's holding in REALOGY, but did reduce the position during the period.

Holdings such as HOVNANIAN ENTERPRISES and WILLIAM LYON HOMES, which we continued to hold, and STANDARD PACIFIC, which we sold by the end of the period, each lagged. We had shifted to a modestly overweight allocation in homebuilders during the first half of the period, seeking to build positions on market weakness given what we believed to be still-attractive longer-term fundamentals. However, it turned out that we bought a bit prematurely, as the housing industry continued to deteriorate during the period, prompting us to reduce the Fund's position in this group to an approximately equal weighting to the JP Morgan Index by the end of the period. Also within the homebuilders area, we moved into more senior parts of companies' capital structures during the second half of the period. For example, we sold subordinated bonds and senior bonds of HOVNANIAN ENTERPRISES and bought senior secured bonds of HOVNANIAN ENTERPRISES instead. Performance from yellow pages publisher R.H. DONNELLEY was disappointing during the period, as pressures on print media grew with the omnipresence of the Internet. Still, we maintained the Fund's sizable position in R.H. DONNELLEY, as we believe the market overreacted and its sell-off was overdone. A holding in subprime auto lender TRIAD ACQUISITION also detracted from the Fund's performance as the credit crunch took hold. However, we believe prospects for a positive outcome in our TRIAD ACQUISITION position remains intact; the Fund continued to hold a position in this issue. CHANGES TO THE FUND'S PORTFOLIO Overall, we sought to use periods of strength in the high yield corporate bond market, such as the rally in April, to reduce the Fund's exposure to lower-rated issues and more cyclical sectors, and to increase its position in higher-rated securities and more defensive areas of the market. More specifically, we completely eliminated the Fund's exposure to the retail sector and reduced its allocation to homebuilders. We increased the Fund's position in energy to a meaningful overweight, as this sector tends to be more defensive and was benefiting from soaring oil and gas prices. We also increased the Fund's exposure to cable TV and satellite cable providers. We added to the Fund's holdings in wireline and wireless telecommunications companies as well. For example, we established a position in the bank debt of ALLTELL. Just after the close of the Fund's fiscal year, ALLTELL announced that it was going to be acquired by Verizon Wireless in a $28 billion deal that will create the biggest mobile phone company in the U.S. We also bought SPRINT ahead of its downgrade from investment grade status during the period in anticipation of just such a move. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 9 MANAGER COMMENTARY (continued) ------------------------------------------------- We strive to select the right bonds while maintaining a diligent review of potential credit risks at individual companies. We added bank loan exposure across certain core holdings in the Fund during periods of market weakness, as these securities tend to be comparatively defensive in nature over time. In many cases, this positioned the Fund in a more senior part of a company's capital structure, thus reducing the overall risk within the portfolio. At the end of the period, the Fund had materially greater exposure than the JP Morgan Index in the energy, health care, cable TV, wireline telecommunications and wireless telecommunications industries, with lesser overweights in the media, chemicals and food industries. Underweights in the Fund's portfolio included the technology, manufacturing and industrial, retail and automotive areas. The Fund also maintained holdings in the gaming and utilities industries, each at approximately equal weighting to the JP Morgan Index. OUR FUTURE STRATEGY In our view, the high yield corporate bond market may well continue to be challenged over the months ahead, as a confluence of factors take hold. These factors include a weaker economy, slowed consumer spending, skyrocketing oil, gas and other commodity prices, a higher default rate and limited access to capital. One of the major questions that faces the market going forward is how the Fed will reconcile the need to both fight inflationary pressures and stimulate the economy. All told, this scenario indicates a difficult environment for the high yield corporate bond market, especially if the Fed chooses to increase rates, as we believe it eventually will. Given that we are in the latter stages of the economic cycle and the risk we see for the further widening of spreads within the high yield corporate bond market, we intend to maintain the Fund's overweight positions in more defensive names and sectors and more modest exposure to cyclical areas of the market. We further intend to continue upgrading credit quality in the -------------------------------------------------------------------------------- 10 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT -------------------------------------------------------------------------------- Fund's portfolio, seeking opportunities to reduce the Fund's position in lower- rated bonds and to move into higher-rated high yield bonds. Going forward, we also believe more than ever that the key to potential outperformance will be leveraging our strength in credit research. We strive to select the right bonds while maintaining a diligent review of potential credit risks at individual companies. We sell bonds when we believe that risks outweigh a bond's total return potential. We have a bottom-up approach when selecting credits. One of our competitive advantages is that our team of nine analysts performs in-depth research to acquire deep knowledge and insight of the industries it covers. We believe that good security selection based on quality and in-depth security research will be key to performance in the near term. We intend, of course, to continue to seek opportunities to capitalize on attractively valued bonds that have the potential for positive returns.

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 May 31, 2008. 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. -------------------------------------------------------------------------------- 14 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT --------------------------------------------------------------------------------

(a) Expenses are equal to the Fund's annualized expense ratio as indicated above, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period). (b) Based on the actual return for the six months ended May 31, 2008: +1.27% for Class A, +0.36% for Class B, +0.87% for Class C, +1.11% for Class I, +0.75% for Class R2, +0.91% for Class R3, +1.41% for Class R4, +1.44% for Class R5 and +0.86% for Class W. (c) The Investment Manager and its affiliates have contractually agreed to waive certain fees and to absorb certain expenses until May 31, 2009, 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 1.02% for Class A, 1.78% for Class B, 1.77% for Class C, 0.65% for Class I, 1.45% for Class R2, 1.20% for Class R3, 0.95% for Class R4, 0.70% for Class R5 and 1.10% for Class W. Any amounts waived will not be reimbursed by the Fund. This change was effective June 1, 2008. Had this change been in place for the entire six month period ended May 31, 2008, the actual expenses paid would have been $5.10 for Class A, $8.87 for Class B, $8.84 for Class C, $3.25 for Class I, $7.24 for Class R2, $5.99 for Class R3, $3.51 for Class R5 and $5.49 for Class W; the hypothetical expenses paid would have been $5.12 for Class A, $8.92 for Class B, $8.87 for Class C, $3.27 for Class I, $7.27 for Class R2, $6.02 for Class R3, $3.52 for Class R5 and $5.52 for Class W.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES RiverSource High Yield Bond Fund (the Fund) is a series of RiverSource High Yield Income Series, Inc. and is registered under the Investment Company Act of 1940 (as amended) as a diversified, open-end management investment company. RiverSource High Yield Income Series, Inc. has 10 billion authorized shares of capital stock that can be allocated among the separate series as designated by the Board of Directors (the Board). The Fund invests primarily in high-yielding, high risk corporate bonds, commonly known as junk bonds. 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 sold with a front-end sales charge. - 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. - Class C shares may be subject to a CDSC. - Class I, Class R2, Class R3, Class R4 and Class R5 shares are sold without a front end sales charge or CDSC and are offered to qualifying institutional investors. - Class W shares are sold without a front-end sales charge or CDSC and are offered through qualifying discretionary accounts. At May 31, 2008, RiverSource Investments, LLC (RiverSource Investments or the Investment Manager) and the RiverSource affiliated funds-of-funds owned 100% of Class I shares and the Investment Manager owned 100% of Class R3 and Class R5 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. 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. -------------------------------------------------------------------------------- 34 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 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. 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 New York Stock Exchange and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange, 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 New York Stock Exchange. 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; those maturing in 60 days or less are valued at amortized cost. ILLIQUID SECURITIES At May 31, 2008, 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. Prior to July 12, 2007, the Fund limited the percent held in securities and other instruments that were illiquid to 10% of the Fund's net assets. The aggregate value of such securities at May 31, 2008 was $20,762,401 representing 1.46% of net assets. These securities may be valued at fair value according to procedures approved, in good faith, 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 -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 35 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 AND UNFUNDED LOAN COMMITMENTS 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 May 31, 2008, the Fund has outstanding when-issued securities of $19,564,135 and other forward-commitments of $4,880,831. The Fund may enter into certain credit agreements, all or a portion of which may be unfunded. The Fund is obligated to fund these loan commitments at the borrower's discretion. These commitments are disclosed in the Portfolio of Investments. At May 31, 2008, the Fund has entered into unfunded loan commitments of $5,497,628. INVESTMENTS IN LOANS The senior loans acquired by the Fund typically take the form of a direct lending relationship with the borrower acquired through an assignment of another lender's interest in a loan. The lead lender in a typical corporate loan syndicate administers the loan and monitors collateral. In the event that the lead lender becomes insolvent, enters FDIC receivership, or, if not FDIC insured, enters into bankruptcy, the Fund may incur certain costs and delays in realizing payment, or may suffer a loss of principal and/or interest. Loans are typically secured but may be unsecured. The primary risk arising from investing in subordinated loans or in unsecured loans is the potential loss in the event of default by the issuer of the loans. 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. Cash collateral may be collected by the Fund to secure certain over-the-counter options trades. Cash collateral held by the Fund for such option trades must be returned to the counterparty upon closure, exercise or expiration of the contract. 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 -------------------------------------------------------------------------------- 36 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 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. At May 31, 2008, and for the year then ended, the Fund had no outstanding option contracts. 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. Futures are valued daily based upon the last sale price at the close of 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. At May 31, 2008, the Fund had no outstanding futures contracts. FOREIGN CURRENCY TRANSLATIONS AND FORWARD 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. The Fund may enter into forward foreign currency 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 -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 37 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. At May 31, 2008, the Fund had no outstanding forward foreign currency contracts. 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 commercial 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 Fund. At May 31, 2008, the Fund had no outstanding CMBS total return swap contracts. CREDIT DEFAULT SWAP TRANSACTIONS The Fund may enter into credit default swap contracts to increase or decrease its credit exposure to an issuer, obligation, portfolio, or index of issuers or obligations, to hedge its exposure on an obligation that it owns or in lieu of selling such obligations. 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 referenced 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). 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 -------------------------------------------------------------------------------- 38 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT specified in the contract occurs, the Fund will receive the referenced 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 received and the notional amount paid will be recorded as a realized gain (loss). As a protection seller, the maximum amount of the payment made by the Fund may equal the notional amount, at par, of the underlying index or security as a result of the related credit event. The notional amounts 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) on the Statement of Operations. At May 31, 2008, there were no credit default swap contracts outstanding which had a premium paid or received by the Fund. 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 agreements only with counterparties that meet certain standards of creditworthiness. 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 the shareholders. No provision for income or excise taxes is thus required. The Fund has adopted Financial Accounting Standards Board (FASB) Interpretation 48 (FIN 48), "Accounting for Uncertainty in Income Taxes," which is effective for fiscal periods beginning after Dec. 15, 2006. 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- -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 39 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. 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 the tax returns filed for the last three years. Net investment income (loss) and net realized gains (losses) may differ for financial statement and tax purposes primarily because of recognition of unrealized appreciation (depreciation) for certain derivative investments, investments in partnerships, 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. On the Statement of Assets and Liabilities, as a result of permanent book-to-tax differences, undistributed net investment income has been decreased by $8,523,183 and accumulated net realized loss has been decreased by $58,996,948 resulting in a net reclassification adjustment to decrease paid-in capital by $50,473,765. The tax character of distributions paid for the years indicated is as follows:

RECENT ACCOUNTING PRONOUNCEMENTS In March 2008, the FASB issued Statement of Financial Accounting Standards No. 161 (SFAS 161), "Disclosures about Derivative Instruments and Hedging Activities - an amendment of FASB Statement No. 133," which requires enhanced disclosures about a fund's derivative and hedging activities. Funds are required to provide enhanced disclosures about (a) how and why a fund uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for under SFAS 133 and its related interpretations, and (c) how -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 41 derivative instruments and related hedged items affect a fund's financial position, financial performance, and cash flows. SFAS 161 is effective for financial statements issued for fiscal years and interim periods beginning after Nov. 15, 2008. As of May 31, 2008, management does not believe the adoption of SFAS 161 will impact the financial statement amounts; however, additional footnote disclosures may be required about the use of derivative instruments and hedging items. On Sept. 20, 2006, the 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 hierarchy for measuring fair value, and requires additional disclosures about the inputs used to develop the measurements of fair value and the effect of certain measurements reported in the Statement of Operations for a fiscal period. The application of SFAS 157 will be effective for the Fund's fiscal year beginning June 1, 2008. The adoption of SFAS 157 is not anticipated to have a material impact on the Fund's financial statements; however, additional disclosures will be required about the inputs used to develop the measurements of fair value and the effect of certain measurements reported in the Statement of Operations for a fiscal period. 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, if any, is recognized on the ex-dividend date. Non-cash dividends or interest included in investment income, if any, are recorded at the fair market value of the security received. Interest income, including amortization of premium, market discount and original issue discount using the effective interest method, is accrued daily. The Fund may place a debt security on non-accrual status and reduce related interest income when it becomes probable that the interest will not be collected and the amount of uncollectible interest can be reasonably estimated. A defaulted debt security is removed from non-accrual status when the issuer resumes interest payments or when collectibility of interest is reasonably assured. 2. 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 is a percentage of the Fund's average daily net assets that declines from 0.59% to -------------------------------------------------------------------------------- 42 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 0.36% annually as the Fund's assets increase. The management fee for the year ended May 31, 2008 was 0.58% of the Fund's average daily net assets. ADMINISTRATIVE SERVICES FEES 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. The fee for the year ended May 31, 2008 was 0.07% 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 year ended May 31, 2008, other expenses paid to the company were $8,708. COMPENSATION OF BOARD MEMBERS Compensation of board members includes, for a former Board Chair, compensation as well as retirement benefits. Certain other aspects of a 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. TRANSFER AGENCY FEES Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer Agent) maintains shareholder accounts and records. 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 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 12 months from the date the account becomes inactive. These fees are included in the transfer agency fees on the Statement of Operations. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 43 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 Distributors, Inc. (the Distributor) for distribution and shareholder services. Prior to Oct. 1, 2007, Ameriprise Financial Services, Inc. also served as a principal underwriter and distributor to the Fund. 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. SALES CHARGES Sales charges received by the Distributor for distributing Fund shares were $698,296 for Class A, $180,498 for Class B and $3,313 for Class C for the year ended May 31, 2008. EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES For the year ended May 31, 2008, 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: Class A..................................................... 1.10% Class B..................................................... 1.86 Class C..................................................... 1.86 Class I..................................................... 0.69 Class R2.................................................... 1.25 Class R3.................................................... 0.99 Class R4.................................................... 0.76 Class R5.................................................... 0.75 Class W..................................................... 1.14
The waived/reimbursed fees and expenses for the transfer agency fees at the class level were as follows: Class R4.................................................... $445

-------------------------------------------------------------------------------- 44 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT Under an agreement which was effective until May 31, 2008, the Investment Manager and its affiliates contractually agreed to waive certain fees and expenses such that net expenses (excluding fees and expenses of acquired funds*), would not exceed the following percentage of the Fund's average daily net assets: Class R4.................................................... 0.95%
Effective June 1, 2008, the Investment Manager and its affiliates have contractually agreed to waive certain fees and expenses until May 31, 2009, unless sooner terminated at the discretion of the Board, such that net expenses (excluding fees and expenses of acquired funds*) will not exceed the following percentage of the Fund's average daily net assets: Class A..................................................... 1.02% Class B..................................................... 1.78 Class C..................................................... 1.77 Class I..................................................... 0.65 Class R2.................................................... 1.45 Class R3.................................................... 1.20 Class R4.................................................... 0.95 Class R5.................................................... 0.70 Class W..................................................... 1.10
In 2005, the Fund received an amended 2003 K-1, for a partnership investment, that reported a smaller loss allocable to the Fund than originally reported. The resulting change to investment income caused taxable dividends on 2004 Forms 1099-DIV to be understated. To resolve this matter, the Fund entered into a closing agreement and in August 2007 paid $433,562 to the Internal Revenue Service. This amount is included in other expenses on the Statement of Operations. Ameriprise Financial reimbursed the Fund for this payment. This amount is included in expenses waived/reimbursed by the Investment Manager and its affiliates on the Statement of Operations. * 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. EARNINGS AND BANK FEE CREDITS During the year ended May 31, 2008, the Fund's custodian and transfer agency fees were reduced by $88,594 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 $1,013,095,267 and $1,313,559,086, respectively, for the -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 45 year ended May 31, 2008. Realized gains and losses are determined on an identified cost basis. Income from securities lending amounted to $71,335 for the year ended May 31, 2008. Expenses paid to the Investment Manager as securities lending agent were $781 for the year ended May 31, 2008, which are included in other expenses on the Statement of Operations. 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. At May 31, 2008, the Fund had no securities out on loan. 4. CAPITAL SHARE TRANSACTIONS Transactions in shares of capital stock for the years indicated are as follows:

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. The cost of the Fund's -------------------------------------------------------------------------------- 46 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT purchases and proceeds from sales of shares of the RiverSource Short-Term Cash Fund aggregated $748,072,445 and $835,284,038, respectively, for the year ended May 31, 2008. The income distributions received with respect to the Fund's investment in RiverSource Short-Term Cash Fund can be found on the Statement of Operations and the Fund's invested balance in RiverSource Short-Term Cash Fund at May 31, 2008, can be found in the Portfolio of Investments. 6. BANK BORROWINGS The Fund has entered into a revolving credit facility 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 credit facility became effective on Oct. 18, 2007, replacing a prior credit facility. The credit facility agreement, which is a collective agreement between the Fund and certain other RiverSource funds, severally and not jointly, permits collective borrowings up to $500 million. Interest is charged to each Fund based on its borrowings at a rate equal to the federal funds rate plus 0.30%. 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 0.06% per annum. Under the prior credit facility, a Fund paid interest on its outstanding 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. The Fund had no borrowings during the year ended May 31, 2008. 7. CAPITAL LOSS CARRY-OVER AND POST-OCTOBER LOSS For federal income tax purposes, the Fund had a capital loss carry-over of $1,320,916,274 at May 31, 2008, that if not offset by capital gains will expire as follows:
2009 2010 2011 2014 2016 $226,001,198 $517,121,802 $552,664,309 $19,078,058 $6,050,907
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, 2007 and its fiscal year end ("post-October loss") as occurring on the first day of the following tax year. At May 31, 2008, the Fund had a post-October loss of $55,632,789 that is treated for income tax purposes as occurring on June 1, 2008. 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. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 47 8. 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 defendants' motion to dismiss the complaint, the 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 on August 8, 2007. 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. 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 -------------------------------------------------------------------------------- 48 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 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. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 49 9.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audit. The financial statements and financial highlights of the Fund for the periods presented through May 31, 2007, were audited by other auditors whose report dated July 20, 2007, expressed an unqualified opinion on those financial statements and financial highlights. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of May 31, 2008, by correspondence with the custodian and brokers, or by other appropriate auditing procedures where replies from brokers were not received. We believe that our audit provides a reasonable basis for our opinion. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 59 In our opinion, the 2008 financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of RiverSource High Yield Bond Fund of the RiverSource High Yield Income Series, Inc. at May 31, 2008, the results of its operations, changes in its net assets and the financial highlights for the year then ended, in conformity with U.S. generally accepted accounting principles. /s/ Ernst & Young LLP Minneapolis, Minnesota July 22, 2008 -------------------------------------------------------------------------------- 60 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT FEDERAL INCOME TAX INFORMATION ------------------------------------------------- (UNAUDITED) The Fund is required by the Internal Revenue Code of 1986 to tell its shareholders about the tax treatment of the dividends it pays during its fiscal year.

-------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 69 APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT ---------------------------------------------------------------------- RiverSource Investments, LLC ("RiverSource Investments" or the "investment manager"), a wholly-owned subsidiary of Ameriprise Financial, Inc. ("Ameriprise Financial"), serves as the investment manager to the Fund. Under an investment management services agreement (the "IMS Agreement") RiverSource Investments provides investment advice and other services to the Fund and all RiverSource funds (collectively, the "Funds"). On an annual basis, the Fund's Board of Directors (the "Board"), including the independent Board members (the "Independent Directors"), considers renewal of the IMS Agreement. RiverSource Investments prepared detailed reports for the Board and its Contracts Committee in March and April 2008, including reports based on data provided by independent organizations to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees) reviews information prepared by RiverSource Investments addressing the services RiverSource Investments provides and Fund performance. The Board accords particular weight to the work, deliberations and conclusions of the Contracts, Investment Review and Compliance Committees in determining whether to continue the IMS Agreement. At the April 9-10, 2008 in-person Board meeting, independent legal counsel to the Independent Directors reviewed with the Independent Directors various factors relevant to the Board's consideration of advisory agreements and the Board's legal responsibilities related to such consideration. Following an analysis and discussion of the factors identified below, the Board, including all of the Independent Directors, approved renewal of the IMS Agreement. Nature, Extent and Quality of Services Provided by RiverSource Investments: The Board analyzed various reports and presentations it had received detailing the services performed by RiverSource Investments, as well as its expertise, resources and capabilities. The Board specifically considered many developments during the past year concerning the services provided by RiverSource Investments, including, in particular, the continued investment in, and resources dedicated to, the Fund's operations, particularly in the areas of trading systems, new product initiatives, legal and compliance. Further, in connection with the Board's evaluation of the overall package of services provided by RiverSource Investments, the Board considered the quality of the administrative and transfer agency services provided by RiverSource Investments' affiliates to the Fund. The Board also reviewed the financial condition of RiverSource Investments (and its affiliates) and each entity's ability to carry out its responsibilities under the IMS Agreement. The Board also discussed the acceptability of the terms of the IMS Agreement (including the relatively broad scope of services required to be performed by RiverSource Investments). The Board concluded that the services being performed under the -------------------------------------------------------------------------------- 70 RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT -------------------------------------------------------------------------------- IMS Agreement were of a reasonably high quality, particularly in light of recent market conditions. Based on the foregoing, and based on other information received (both oral and written, including the information on investment performance referenced below) and other considerations, the Board concluded that RiverSource Investments and its affiliates were in a position to continue to provide a high quality and level of services to the Fund. Investment Performance: For purposes of evaluating the nature, extent and quality of services provided under the IMS Agreement, the Board carefully reviewed the investment performance of the Fund. In this regard, the Board considered: (i) detailed reports containing data prepared by an independent organization showing, for various periods, the performance of the Fund, the performance of a benchmark index, the percentage ranking of the Fund among its comparison group and the net assets of the Fund; and (ii) a report detailing the Fund's performance over various periods (including since inception), recent Fund inflows (and outflows) and a comparison of the Fund's net assets from December 2006 to December 2007. The Board observed that the Fund's investment performance was appropriate in light of the particular management style and market conditions involved. Comparative Fees, Costs of Services Provided and the Profits Realized By RiverSource Investments and its Affiliates from their Relationships with the Fund: The Board reviewed comparative fees and the costs of services to be provided under the IMS Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (prepared by an independent organization) showing a comparison of the Fund's expenses with median expenses paid by funds in its peer group, as well as data showing the Fund's contribution to RiverSource Investments' profitability. The Board accorded particular weight to the notion that the level of fees should reflect a rational pricing model applied consistently across the various product lines in the Funds' family, while assuring that the overall fees for each fund are generally in line with the "pricing philosophy" (i.e., that the total expense ratio of each fund, with few exceptions, is at or below the median expense ratio of funds in the same comparison group). The Board observed that the Fund's expense ratio (after considering proposed expense caps/waivers) approximated the peer group's median expense ratio. Based on its review, the Board concluded that the Fund's management fee was fair and reasonable in light of the extent and quality of services that the Fund receives. -------------------------------------------------------------------------------- RIVERSOURCE HIGH YIELD BOND FUND -- 2008 ANNUAL REPORT 71 APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT (continued) ---------------------------------------------------------- The Board also considered the expected profitability of RiverSource Investments and its affiliates in connection with RiverSource Investments providing investment management services to the Fund. In this regard, the Board referred to a detailed profitability report, discussing the profitability to RiverSource Investments and Ameriprise Financial from managing and operating the Fund, including data showing comparative profitability over the past two years. The Board also considered the services acquired by the investment manager through the use of commission dollars paid by the Funds on portfolio transactions. The Board noted that the fees paid by the Fund should permit the investment manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. The Board concluded that profitability levels were reasonable. Economies of Scale to be Realized: The Board also considered the economies of scale that might be realized by RiverSource Investments as the Fund grows and took note of the extent to which Fund shareholders might also benefit from such growth. The Board considered that the IMS Agreement provides for lower fees as assets increase at pre-established breakpoints and concluded that the IMS Agreement satisfactorily provided for sharing these economies of scale. Based on the foregoing, the Board, including all of the Independent Directors, concluded that the investment management service fees were fair and reasonable in light of the extent and quality of services provided. In reaching this conclusion, no single factor was determinative. On April 10, 2008, the Board, including all of the Independent Directors, approved the renewal of the IMS Agreement.
