By order of the Board of Directors Leslie L. Ogg, Secretary Dec. 16, 2005 RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 2 <Page> COMBINED PROXY STATEMENT/PROSPECTUS DATED DEC. 16, 2005 This document is a proxy statement for New Dimensions and a prospectus for Large Cap Equity (each individually a "Fund" and collectively the "Funds"). It contains the information you should know before voting on the proposal. Please read it carefully and keep it for future reference. The address of each of the Funds is 901 Marquette Avenue South, Suite 2810, Minneapolis, MN 55402-3268. The phone number for each of the Funds is (612) 330-9283. The following information describes the proposed reorganization of the Selling Fund into the Buying Fund (the "Reorganization"). HOW THE REORGANIZATION WILL WORK - - The Selling Fund will transfer all of its assets to the Buying Fund. The Buying Fund will assume the Selling Fund's liabilities. - - The Buying Fund will issue shares of Classes A, B, C, I and Y to the Selling Fund in an amount equal to the value of the assets of Classes A, B, C, I and Y that it receives from the Selling Fund, less the liabilities it assumes. These shares will be distributed to the Selling Fund's shareholders in proportion to their holdings in the Selling Fund. You will not pay any sales charge in connection with this distribution of shares. If you already have a Buying Fund account, shares distributed in the Reorganization will be added to that account. As a result, when average cost is calculated for income tax purposes, the cost of the shares in the two accounts you owned will be combined. FUND INVESTMENT OBJECTIVES The investment objective for each of the Funds is as follows: SELLING FUND: The Fund seeks to provide shareholders with long-term growth of capital. BUYING FUND: The Fund seeks to provide shareholders with long-term growth of capital. Please note that the Fund is not a bank deposit, is not federally insured, is not endorsed by any bank or government agency and is not guaranteed to achieve its goal.

APPROVE OR REJECT THE AGREEMENT AND PLAN OF REORGANIZATION SUMMARY This proxy statement/prospectus is being used by the Selling Fund to solicit proxies to vote at a meeting of shareholders. Shareholders will consider a proposal to approve the Agreement providing for the Reorganization of the Selling Fund into the Buying Fund. A form of the Agreement is included in Exhibit A. The following is a summary. More complete information appears later in this proxy statement/prospectus. You should read the entire proxy statement/prospectus and the exhibits because they contain details that are not in the summary. HOW THE REORGANIZATION WILL WORK - - The Selling Fund will transfer all of its assets to the Buying Fund. The Buying Fund will assume the Selling Fund's stated liabilities. - - The Buying Fund will issue shares of Classes A, B, C, I and Y to the Selling Fund in an amount equal to the value of the assets of Classes A, B, C, I and Y that it receives from the Selling Fund, less the liabilities it assumes. These shares will be distributed to the Selling Fund's shareholders in proportion to their holdings in the Selling Fund. - - As part of the Reorganization, systematic transactions (such as bank authorizations and systematic payouts) currently set up for your Selling Fund account will be transferred to your new Buying Fund account. If you do not want your systematic transactions to continue, please contact your financial advisor to make changes. - - Neither the Selling Fund nor the shareholders of the Selling Fund will pay any sales charge in connection with the Reorganization. - - After the Reorganization is completed, current Selling Fund shareholders will be shareholders of the Buying Fund. The Selling Fund will be terminated. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 7 <Page> COMPARISON OF THE SELLING FUND AND THE BUYING FUND Both the Selling Fund and the Buying Fund: - - Are structured as a series of capital stock of an open-end management investment company organized as a Minnesota corporation. - - Have RiverSource Investments, LLC (the "investment manager" or "RiverSource Investments") as an investment adviser. - - Have the same policies for buying and selling shares and the same exchange rights. - - Have the same distribution policies. - - Have different classes of shares: Classes A, B, C, I and Y. COMPARISON OF INVESTMENT OBJECTIVES The investment objectives for the Funds are as follows: SELLING FUND: The Fund seeks to provide shareholders with long-term growth of capital. BUYING FUND: The Fund seeks to provide shareholders with long-term growth of capital. COMPARISON OF INVESTMENT STRATEGIES Prior to October 2005, the Selling Fund was managed as a large-cap growth fund and was permitted to invest up to 30% of its total assets in foreign investments. The Buying Fund has, and, since October 2005, the Selling Fund has had, a policy to invest at least 80% of its net assets in the common stocks of equity securities of large-cap companies with market capitalization greater than $5 billion at the time of purchase. Additionally, the Buying Fund is, and, since October 2005, the Selling Fund has been, managed as a core fund, with portions of the Fund's portfolio uniquely dedicated to "growth," "value," and "core" investing, with no more than 20% of total assets permitted to invest in foreign investments. Detailed strategies for the Selling Fund and the Buying Fund are set forth below: NEW DIMENSIONS (SELLING FUND): UNTIL OCTOBER 2005, THE FUND WAS MANAGED AS FOLLOWS: The Fund primarily invests in common stocks showing potential for significant growth. These companies often operate in areas where dynamic economic and technological changes are occurring. The Fund may invest up to 30% of its total assets in foreign investments. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 8 <Page> In pursuit of the Fund's goal, the investment manager chooses investments by: - - Identifying companies that the investment manager believes have above-average long-term growth potential based on: - - Effective management, - - Financial strength, and - - Competitive market position; as well as - - Considering opportunities and risks by reviewing interest rate and economic forecasts both domestically and abroad. In evaluating whether to sell a security, the investment manager considers, among other factors, whether: - - The security is overvalued relative to alternative investments. - - The company has met the investment manager's earnings and/or growth expectations. - - Political, economic, or other events could affect the company's performance. - - The investment manager wishes to minimize potential losses. - - The investment manager identifies a more attractive opportunity. SINCE OCTOBER 2005, THE FUND HAS BEEN MANAGED IN THE SAME WAY AS LARGE CAP EQUITY BELOW: LARGE CAP EQUITY (BUYING FUND): Under normal market conditions, at least 80% of the Fund's net assets are invested in equity securities of companies with a market capitalization greater than $5 billion at the time of purchase. The Fund may invest in income-producing equity securities, such as dividend-paying stocks, convertible securities and preferred stocks. The Fund will provide shareholders with at least 60 days' notice of any change in the 80% policy. In pursuit of the Fund's objective, the investment manager (RiverSource Investments, LLC) will hold both growth and value companies and at times may favor one more than the other based on available opportunities. When optimizing for growth, the investment manager invests in companies it believes to have above-average long-term growth potential, or technological superiority, and it selects investments based, among other factors, on: - - Effective management. - - Financial strength. - - Competitive market or product position. - - Technological advantage relative to other companies. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 9 <Page> When optimizing for value, the investment manager invests in companies that appear to be undervalued by various measures or that may be temporarily out of favor, but have good prospects for capital appreciation, and it selects investments based, among other factors, on: - - Identifying a variety of large, well-established companies whose underlying fundamentals are stable, or are anticipated to become stable, or whose fundamentals are improving. - - Identifying stocks that are undervalued: - - because they have one or more ratios, such as price-to-earnings or price-to-cash flow, that are low relative to the general market, or have a yield that exceeds the market, - - because one or more of their valuation ratios are low relative to historical levels for the stock, - - because one or more of their valuation ratios or other financial measures make that stock attractive relative to its peers, or - - because they are undervalued relative to their intrinsic value, as identified by the investment manager. In evaluating whether to sell a security, the investment manager considers factors including, among others whether: - - The security is overvalued relative to other potential investments. - - The security has reached the investment manager's price objective. - - The company has met the investment manager's earnings and/or growth expectations. - - Potential losses, due to factors such as a market down-turn, can be minimized. - - A more attractive opportunity has been identified. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 10 <Page> BOTH FUNDS: - - UNUSUAL MARKET CONDITIONS. During unusual market conditions, each of the Funds may invest more of its assets in money market securities than during normal market conditions. Although investing in these securities would serve primarily to avoid losses, this type of investing could prevent the Fund from achieving its investment objective. During these times, the investment manager may make frequent securities trades that could result in increased fees, expenses and taxes, and decreased performance. - - OTHER INVESTMENT STRATEGIES. Each Fund may invest in other securities and may use other investment strategies that are not principal investment strategies. Additionally, the Fund may use derivatives (financial instruments where the value depends upon, or is derived from, the value of something else) such as futures, options and forward contracts, to produce incremental earnings, to hedge existing positions or to increase flexibility. Just as with securities in which the Fund invests directly, derivatives are subject to a number of risks, including market, liquidity, interest rate and credit risk. In addition, a relatively small price movement in the underlying security, currency or index may result in a substantial gain or loss for the Fund using derivatives. Even though the Fund's policies permit the use of derivatives in this manner, the investment manager is not required to use derivatives. COMPARISON OF FUNDAMENTAL POLICIES The Buying Fund shareholders will vote on changes to the fundamental policies for the Buying Fund at a meeting scheduled to be held on the same day as the Selling Fund shareholder meeting. The proposed changes are shown in Exhibit B. If all of the proposed changes to the Buying Fund's fundamental policies are approved, the differences in investment policies will be as follows: Each Fund has substantially similar fundamental investment policies. The Buying Fund has a policy permitting borrowing money for temporary purposes in an amount not exceeding one-third of the market value of its total assets. The Selling Fund has a similar policy that applies to money or property and permits borrowing only for extraordinary or emergency purposes. The Buying Fund has a policy prohibiting the issuing of senior securities, except as permitted under the 1940 Act. Even though this is not stated as a fundamental policy of the Selling Fund, the Fund is nonetheless subject to that restriction under the provisions of the 1940 Act. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 11 <Page> The Buying Fund has a policy permitting the Fund to lend fund securities and participate in an interfund lending program up to 33 1/3% of the value of the Fund's total assets. This policy does not prohibit the Buying Fund from purchasing money market securities, loans, loan participation or other debt securities, or from entering into repurchase agreements. The Selling Fund has a policy permitting the Selling Fund to lend fund securities up to 30% of its net assets. In addition, the Selling Fund has a policy that it may make cash loans up to 5% of its total assets. The Selling Fund has a policy prohibiting loans to the investment manager, its board members and officers and to the board members and officers of the Selling Fund. The Buying Fund has a policy that it will not purchase more than 10% of the outstanding voting securities of an issuer, except up to 25% of its total assets may be invested without regard to this 10% limitation. The Selling Fund has a similar policy, but does not have the 25% exception. The Buying Fund has a policy that it will not invest more than 5% of its total assets in securities of any one company, government, or political subdivision thereof, except the limitation will not apply to investments in securities issued by the U.S. government, its agencies, or instrumentalities, or other investment companies, and except that up to 25% of its total assets may be invested without regard to this 5% limitation. The Selling Fund has a similar policy, but does not include other investment companies in the exception. If shareholders of the Selling Fund approve the Reorganization, they will be subject to the fundamental investment policies of the Buying Fund. The investment manager does not believe that the differences between the fundamental investment policies will result in any material difference in the way the Funds are managed. RISK FACTORS Prior to October 2005, the Selling Fund had increased risks of style specific investing, highlighted in Market Risk, as the fund emphasized growth stocks. Since October 2005, the principal risks of investing in each of the Selling Fund and the Buying Fund are identical and are shown below: <Table> <Caption> NEW DIMENSIONS NEW DIMENSIONS RISK UNTIL OCT. 2005 SINCE OCT. 2005 LARGE CAP EQUITY Active Management Risk x x x Foreign Risk x Issuer Risk x x x Market Risk x x x </Table> RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 12 <Page> - - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance therefore will reflect in part the investment manager's ability to make investment decisions that are suited to achieving the Fund's investment objective. Due to its active management, the Fund could underperform other mutual funds with similar investment objectives. - - FOREIGN RISK. The following are all components of foreign risk: COUNTRY RISK includes the political, economic, and other conditions of the country. These conditions include lack of publicly available information, less government oversight (including lack of accounting, auditing, and financial reporting standards), the possibility of government-imposed restrictions, and even the nationalization of assets. The liquidity of foreign investments may be more limited than for most U.S. investments, which means that, at times it may be difficult to sell foreign securities at desirable prices. CURRENCY RISK results from changing exchange rate between local currency and the U.S. dollar. Whenever the Fund holds securities valued in a foreign currency or holds the currency, changes in the exchange rate add or subtract from the value of the investment. CUSTODY RISK refers to the process of clearing and settling trades. It also covers holding securities with local agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle. Local agents are held only to the standard of care of the local market. Governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. The less developed a country's securities market is, the greater the likelihood of problems occurring. The liquidity of foreign investments may be more limited than for most U.S. investments, which means that, at times it may be difficult to sell foreign securities at desirable prices. - - ISSUER RISK. An issuer may perform poorly and therefore, the value of its stocks and bonds may decline. Poor performance may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, or other factors. - - MARKET RISK. The market value of securities may fall or fail to rise. Market risk may affect a single issuer, sector of the economy, industry, or the market as a whole. The market value of all securities may fluctuate, sometimes rapidly and unpredictably. This risk is generally greater for small and mid-sized companies, which tend to be more vulnerable to adverse developments. In addition, focus on a particular style, for example, investment in growth or value securities, may cause the Fund to underperformance other mutual funds if that style falls out of favor with the market.

TAX CONSEQUENCES The Reorganization is expected to be tax-free for federal income tax purposes and will not take place unless the Selling Fund and the Buying Fund receive a satisfactory opinion of tax counsel, substantially to that effect. Accordingly, no gain or loss is expected to be recognized by the Selling Fund or its shareholders as a direct result of the Reorganization. Prior to or after completion of the Reorganization, no major sell-offs to realign the portfolio are expected in relation to, or as a result of the Reorganization. However, the Reorganization will end the tax year of the Selling Fund, and so it will accelerate distributions from the Selling Fund for its short tax year ending on the date of the Reorganization to you as a shareholder. Those tax year-end distributions, which are taxable, will also include any capital gains resulting from portfolio turnover prior to the implementation of the Reorganization. At any time prior to the consummation of the Reorganization a shareholder may redeem shares. This would likely result in recognition of gain or loss to the shareholder for federal income tax purposes. The tax basis and holding period of the shareholders' Selling Fund shares is expected to carry over to the shareholders' new shares in the Buying Fund. For more information about the federal income tax consequences of the Reorganization, see the section entitled "Tax Status of the Reorganization." RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 14 <Page> FEES AND EXPENSES The following table describes the fees and expenses adjusted to reflect current fees that you pay if you buy and hold shares of the Selling Fund or shares of the Buying Fund. The table also shows pro forma expenses of the Buying Fund assuming the proposed Reorganization had been effective during the most recent fiscal year, adjusted to reflect current fees.

(a) This charge may be reduced depending on the value of your total investments in RiverSource mutual funds. (b) For Class A purchases over $1,000,000 on which no sales charge is assessed, a 1% sales charge may apply if you sell your shares within one year after purchase. (c) The management fee rate is the actual fee rate charged as of fiscal year ended July 31, 2005. It includes the impact of a performance incentive adjustment that decreased the management fee by 0.07%. Prior to November 2005 the index against which New Dimensions performance was measured for purposes of determining the performance incentive adjustment was the Lipper Large-Cap Growth Funds Index. Since November 2005, the index against which New Dimensions performance is measured for purposes of determining the performance incentive adjustment is the Lipper Large Cap Core Funds Index. Should this Reorganization not be approved, there is a separate proposal to modify the management fee schedule. Under the new fee schedule, the projected management fee ratio based on average net assets as of July 31, 2005, net of the 0.07% performance incentive adjustment decrease, is 0.44%. (d) Other expenses include an administrative services fee, a custody fee, a transfer agency fee, other nonadvisory expenses and, for Class Y shares, a shareholder service fee. The other expense ratios shown in this chart have been adjusted to reflect the new administrative fee that went into effect October 2005. (e) The management fee ratio shown reflects what the ratio would be based on the fund's average net assets as of July 31, 2005 under the proposed management fee schedule. The ratio includes the impact of a performance incentive adjustment that decreased the management fee by 0.02%. The index against which the Fund's performance is measured for purposes of determining the performance incentive adjustment is the Lipper Large-Cap Core Funds Index. (f) The management fee ratio shown reflects what the ratio would be under the proposed management fee schedule based on the combined average net assets of the two funds as of July 31, 2005. It includes the impact of a performance incentive adjustment that decreased the management fee by 0.02%. It also includes the impact of a special management fee waiver that will be in effect until August 2006 on the merged fund. This special management fee waiver is estimated to reduce the management fee ratio by 0.01%. The index against which the Fund's performance is measured for purposes of determining the performance incentive adjustment is the Lipper Large-Cap Core Funds Index. (g) New Dimensions is a feeder fund that is part of a master/feeder structure. For New Dimensions, both in this table and the following example, fund operating expenses include expenses charged by both the Fund and its Master Portfolio. (h) Other expenses include an administrative services fee, a custody fee, a transfer agency fee, other nonadvisory expenses and, for Class Y shares, a shareholder services fee. The other expense ratios shown in this chart have been adjusted to reflect the new administrative fee that went into effect in October 2005. In addition, these ratios have been adjusted to reflect closed account fees following the Reorganization and an anticipated reduction in transfer agent fees due to the New Dimensions and Large Cap Equity accounts that will be combined as a result of the Reorganization. EXAMPLE: These examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. These examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods indicated under the current arrangements and if the proposed Reorganization had been in effect. These examples also assume that your investment has a 5% return each year and that the Fund's operating expenses remain the same.

THE REORGANIZATION TERMS OF THE REORGANIZATION The Board has approved the Agreement, a copy of which is attached as Exhibit A. The Agreement provides for Reorganization on the following terms: - - The Reorganization is scheduled to occur on the first day that the New York Stock Exchange is open for business following shareholder approval and receipt of any necessary regulatory approvals, but may occur on any later date agreed to by the Selling Fund and the Buying Fund. - - The Selling Fund will transfer all of its assets to the Buying Fund and, in exchange, the Buying Fund will assume the Selling Fund's stated liabilities. - - The Buying Fund will issue Class A, B, C, I and Y shares to the Selling Fund in an amount equal to the value of the assets of Classes A, B, C, I and Y that it receives from the Selling Fund, less the liabilities assumed by the Buying Fund in the transaction. These shares will immediately be distributed by the Selling Fund to its shareholders in proportion to their holdings in the Selling Fund. As a result, shareholders of the Selling Fund will become Class A, B, C, I or Y shareholders of the Buying Fund. - - Neither the Selling Fund nor the shareholders of the Selling Fund will pay any sales charge in connection with the Reorganization. - - The net asset value of the Selling Fund and the Buying Fund will be computed as of 3:00 p.m. Central time, on the closing date. - - After the Reorganization, the Selling Fund will be terminated. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 18 <Page> CONDITIONS TO CLOSING THE REORGANIZATION The completion of the Reorganization is subject to certain conditions described in the Agreement, including: - - The Selling Fund will have declared and paid a dividend that will distribute all of the Fund's taxable income, if any, to the shareholders of the Fund for the taxable years ending at or prior to the closing. - - The Funds will have received any approvals, consents or exemptions from the SEC or any regulatory body necessary to carry out the Reorganization. - - A registration statement on Form N-14 will have been filed with the SEC and declared effective. - - The shareholders of the Selling Fund will have approved the Agreement. - - The Selling Fund will have received an opinion of tax counsel that the proposed Reorganization will result in no gain or loss being recognized by any shareholder. TERMINATION OF THE AGREEMENT The Agreement and the transactions contemplated by it may be terminated and abandoned by resolutions of the Board of the Selling Fund or the Buying Fund at any time prior to closing. In the event of a termination, there will be no liability for damages on the part of either the Selling Fund or the Buying Fund or the directors, officers or shareholders of the Selling Corporation or of the Buying Corporation. TAX STATUS OF THE REORGANIZATION The Reorganization is expected to be tax-free for federal income tax purposes and will not take place unless the Selling Fund and the Buying Fund receive a satisfactory opinion of tax counsel (which opinion will be based on certain factual representations and certain customary assumptions), to the effect that, although not entirely free from doubt, on the basis of existing provisions of the Internal Revenue Code of 1986, as amended (the "Code"): - - The transfer of the Selling Fund's assets to the Buying Fund in exchange for Class A, B, C, I and Y shares of the Buying Fund and the assumption of the Selling Fund's liabilities, followed by the distribution of those Class A, B, C, I and Y shares to the Selling Fund's shareholders and the termination of the Selling Fund will be a "reorganization" within the meaning of Section 368(a)(1) of the Code, and the Selling Fund and the Buying Fund will each be a "party to the reorganization" within the meaning of Section 368(b) of the Code. - - Under Section 361 of the Code, no gain or loss will be recognized by the Selling Fund upon the transfer of all of its assets to the Buying Fund or on the distribution by the Selling Fund of Class A, B, C, I and Y shares of the Buying Fund to Selling Fund shareholders in liquidation. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 19 <Page> - - Under Section 354 of the Code, the shareholders of the Selling Fund will not recognize gain or loss upon the exchange of their Class A, B, C, I or Y shares of the Selling Fund solely for Buying Fund Class A, B, C, I or Y shares as part of the Reorganization. - - Under Section 358 of the Code, the aggregate basis of the Class A, B, C, I or Y shares of the Buying Fund that a Selling Fund shareholder receives in the Reorganization will be the same as the aggregate basis of the Class A, B, C, I or Y shares of the Selling Fund exchanged therefor. - - Under Section 1223(1) of the Code, the tax holding period for the Class A, B, C, I or Y shares of the Buying Fund that a Selling Fund shareholder receives in the Reorganization will include the period for which he or she held the Class A, B, C, I or Y shares of the Selling Fund exchanged therefor, provided that on the date of the exchange he or she held such Selling Fund shares as capital assets. - - Under Section 1032 of the Code, no gain or loss will be recognized by the Buying Fund upon the receipt of the Selling Fund's assets solely in exchange for the issuance of Buying Fund's Class A, B, C, I and Y shares to the Selling Fund and the assumption of all of the Selling Fund's liabilities by the Buying Fund. - - Under Section 362(b) of the Code, the Buying Fund's tax basis in the assets that the Buying Fund received from the Selling Fund will be the same as the Selling Fund's tax basis in those assets immediately prior to the transfer. - - Under Section 1223(2) of the Code, the Buying Fund's holding periods in the assets received from the Selling Fund will include the Selling Fund's holding periods in such assets. - - Under Section 381 of the Code, the Buying Fund will succeed to and take into account the items of the Selling Fund described in Section 381(c) of the Code, subject to the conditions and limitations specified in Sections 381, 382, 383 and 384 of the Code and Regulations thereunder. Tax counsel will express no view with respect to the effect of the Reorganization on any transferred assets as to which any unrealized gain or loss is required to be recognized at the end of a taxable year (or on the termination or transfer thereof) under federal income tax principles. Prior to the closing of the Reorganization, the Selling Fund will, and the Buying Fund may, declare a distribution to shareholders, which together with all previous distributions, will have the effect of distributing to shareholders all of its investment company taxable income (computed without regard to the deduction for dividends paid) and net realized capital gains (after reduction by any available capital loss carryforwards), if any, through the closing of the Reorganization. These distributions will be taxable to shareholders. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 20 <Page> A fund's ability to carry forward capital losses and use them to offset future gains may be limited. First, one fund's "pre-acquisition losses" (including capital loss carryforwards, net current-year capital losses, and unrealized losses that exceed certain thresholds) cannot be used to offset unrealized gains in another fund that are "built in" at the time of the reorganization and that exceed certain thresholds ("non-de minimis built-in gains") for five tax years. Second, a portion of a fund's pre-acquisition losses may become unavailable to offset any gains at all. Third, any remaining pre-acquisition losses will offset capital gains realized after a reorganization and thus will reduce subsequent capital gain distributions to a broader group of shareholders than would have been the case absent such reorganization. Therefore, in certain circumstances, former shareholders of a fund may pay taxes sooner, or pay more taxes, than they would have had a reorganization not occurred. The impact of the rules described above will depend on the relative sizes of, and the losses and gains in, each fund at the time of the Reorganization. As stated above, for five years beginning after the closing date, the combined fund will not be allowed to offset gains "built in" to either fund at the time of the Reorganization against capital losses (including capital loss carryforwards) built in to the other fund. However, as of August 31, 2005, the other two rules mentioned in the immediately preceding paragraph would not have affected the Selling Fund directly because the Selling Fund's net realized and unrealized gains exceeded its capital loss carryforwards and thus the Selling Fund had no pre-acquisition "net losses" (i.e., capital loss carryforwards as of its last fiscal year end as adjusted by year-to-date realized gains or losses and all net unrealized gains) that would have become unavailable to offset gains or been spread over a broader group of shareholders. However, a portion of the Buying Fund's losses would have been lost. The realized and unrealized gains and losses of each Fund at the time of the Reorganization will determine the extent to which the combining Funds' respective losses, both realized and unrealized, will be available to reduce gains realized by the combined Fund following the Reorganization, and consequently the extent to which the combined Fund may be required to distribute gains to its shareholders earlier than would have been the case absent the Reorganization. This description of the federal income tax consequences of the Reorganization does not take into account your particular facts and circumstances. Consult your own tax adviser about the effect of state, local, foreign, and other tax laws. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 21 <Page> REASONS FOR THE PROPOSED REORGANIZATION AND BOARD DELIBERATIONS The Board believes that the proposed Reorganization will be advantageous to Selling Fund shareholders based on its consideration of the following matters: - - TERMS AND CONDITIONS OF THE REORGANIZATION. The Board considered the terms and conditions of the Reorganization as described in the previous paragraphs. - - TAX CONSEQUENCES. The Board considered the tax-free nature of the Reorganization. - - CONTINUITY OF INVESTMENT. The Board took into account the fact that, currently, the Selling Fund and the Buying Fund have an identical investment objective and identical investment strategies and that, as a result, both Funds are, in fact, managed in substantially the same way. The Board took note of the fact that following the Reorganization, shareholders of the Selling Fund will be invested in a fund holding a substantially similar investment securities portfolio to the portfolio currently held by the Selling Fund. - - EXPENSE RATIOS. The Board considered the relative expenses of the Funds. As of the end of each Fund's most recent fiscal year, the expense ratios for the Buying Fund were higher than the expense ratios for the Selling Fund. For example, the Selling Fund's expense ratio for Class A shares as of July 31, 2005, its most recent fiscal year end, adjusted to reflect current fees (after giving effect to the performance incentive adjustment) was 0.96% (1.03% before giving effect to the performance incentive adjustment). The Buying Fund's expense ratio for Class A shares as of July 31, 2005, its most recent fiscal year end, adjusted to reflect current fees (after giving effect to the performance incentive adjustment) was 1.18% (1.20% before giving effect to the performance incentive adjustment). The Board considered that the Funds have the same management and administrative fee schedules with the same breakpoints, and that the Selling Fund's lower ratio is primarily attributable to the fact that it has realized additional breakpoints in its fee schedules because of its larger asset size. Therefore, the Board considered that, after taking into account the effect of the Reorganization (that is, the combination of the Selling Fund's assets with those of the Buying Fund), the Buying Fund's Class A expense ratio would experience a reduction (as new breakpoints are reached) and would, as a result, closely approximate the current Class A expense ratio of the Selling Fund (the pro forma expense ratio of the Buying Fund on July 31, 2005, restated to take into account the effect of the Reorganization, is one basis point lower than the Selling Fund's expense ratio on that date). In conducting this analysis, the Board did not take into account the effect of any performance incentive adjustment on the Selling Fund's or Buying Fund's expense ratio. The Board also considered that higher aggregate net assets resulting from the Reorganization and the RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 22 <Page> opportunity for net cash inflows (or reduced outflows) may reduce the risk that, if net assets of the Selling Fund fail to grow, or diminish, its total expense ratio could rise from current levels as fixed expenses become a larger percentage of net assets. - - ECONOMIES OF SCALE. The Board considered the advantage of combining Funds that share an identical investment objective and identical investment strategies. The Board believes that by combining the Funds, the combined fund can take advantage of the economies of scale associated with a larger fund. For example, a larger fund should have an enhanced ability to effect portfolio transactions on more favorable terms and should have greater investment flexibility. Furthermore, as indicated above, fixed expenses, such as audit expenses and accounting expenses that are charged on a per fund basis, will be reduced. - - COSTS. The Board considered the fact that the investment manager has agreed to bear all solicitation expenses in order to achieve shareholder approval of the Reorganization and to bear any other costs of effecting the Reorganization (the filing, closing and other costs of consummating the transaction). - - DILUTION. The Board considered the fact that the Reorganization will not dilute the interests of the current shareholders because it would be effected on the basis of the relative net asset value per share of the Selling Fund and Buying Fund, respectively. Thus, a Class A shareholder of the Selling Fund will receive Class A shares of the Buying Fund equal in value to his or her Class A shares in the Selling Fund. - - PERFORMANCE AND OTHER FACTORS. The Board considered the relative performance records of the funds. The Board took into account the better overall track record of the Buying Fund, when compared to the Selling Fund, over the past three years, noting that the difference in performance between the two funds was attributable to the fact that, prior to October 2005, both Funds had materially different investment strategies. While the Board was cognizant of the fact that the Buying Fund's past performance is no guarantee of its future results, it did recognize that the better three year track record of the Buying Fund could help attract more assets into the combined fund and therefore could help reduce the rate of outflows that have been experienced by the Selling Fund. The Board considered that reduced outflows or increased inflows could help the Selling Fund shareholders achieve further economies of scale (see "Economies of Scale" above). The Board also considered the fact that the funds have an identical investment objective, and, since October 2005, the same investment strategies, and substantially similar holdings and, absent the Reorganization, the two funds are likely to compete against each other for the same investor RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 23 <Page> base and, thus, could draw assets away from the other fund. The Reorganization should allow for a concentrated selling effort thereby potentially benefiting both funds. The Board further took into account the investment manager's belief that the Selling Fund, as a stand-alone fund, was unlikely to experience any growth in assets as a result of investor inflows. - - POTENTIAL BENEFITS TO THE INVESTMENT MANAGER AND ITS AFFILIATES. The Board also considered the potential benefits from the Reorganization that could be realized by the investment manager and its affiliates. The Board recognized that the potential benefits to the investment manager consist principally of the elimination of expenses incurred in duplicative efforts to administer separate funds. The Board also noted, however, that shareholders of the Selling Fund will benefit over time from any decrease in overall operating expense ratios resulting from the proposed Reorganization. BOARDS' DETERMINATIONS After considering the factors described above and other relevant information, at a meeting held on Nov. 9-10, 2005, the Selling Fund Board members, including a majority of the independent Board members, found that participation in the Reorganization is in the best interests of the Selling Fund and that the interests of existing shareholders of the Fund will not be diluted as a result of the Reorganization. The Board of Directors of the Buying Fund approved the Agreement at a meeting held on Nov. 9-10, 2005. Among other factors, the Board members considered the terms of the Agreement, the provisions intended to avoid the dilution of shareholder interests and the anticipated tax consequences of the Reorganization. The Board found that participation in the Reorganization is in the best interests of the Buying Fund and that the interests of existing shareholders of the Buying Fund will not be diluted as a result of the Reorganization. RECOMMENDATION AND VOTE REQUIRED The Board recommends that shareholders approve the proposed Agreement. The Agreement must be approved by a majority of the voting power of all shares entitled to vote. If the Agreement is not approved, the Board will consider what further action should be taken. If shareholders approve the Reorganization, it will take place shortly after the shareholder meeting. During the period between the shareholder meeting and the Reorganization, or if the Reorganization is not approved, it will be important for the Fund to have a properly elected Board and an IMS Agreement that has been approved by shareholders. Therefore, the Board is also recommending that shareholders approve the other proposals. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 24 <Page> PROPOSAL 2.

RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 28 <Page> BOARD COMMITTEES. The Board has several committees that facilitate the work of the Board. The Executive Committee has authority to act for the full Board between meetings. The Contracts Committee receives and analyzes reports covering the level and quality of services provided under contracts with the fund and advises the Board regarding actions taken on these contracts during the annual review process. The Investment Review Committee considers investment management policies and strategies; investment performance; risk management techniques; and securities trading practices and reports areas of concern to the Board. The Board Effectiveness Committee's charter, Exhibit E, requires it to make recommendations regarding nominees based on criteria approved by the Board. All members of the Committee are independent. Nominee recommendations are based on a matrix of skill sets, experience, and geographical location and each nominee must have a background that demonstrates the ability to furthering the interest of all shareholders. The Committee will consider recommendations from shareholders who write to the Boards and provide detailed information about a candidate. All candidates are processed in the same fashion; first by evaluating a candidate's detailed information against the criteria; then interviewing those candidates who best fill vacancies identified by the matrix. You may write the Board by addressing a letter to Arne H. Carlson, the independent Chair of the Board or any other independent member of the Board, at Board Services Corporation, 901 Marquette Avenue South, Suite 2810, Minneapolis, MN 55402-3268. However, do not address letters to this address if you are requesting some action regarding your investments. In order to avoid any delay in processing a request regarding an investment, please address these requests to 70100 Ameriprise Financial Center, Minneapolis, MN 55474. The Joint Audit Committee, made up entirely of independent Board members, operates under a written charter, Exhibit F. The Joint Audit Committee meets with the independent auditors, internal auditors and corporate officers to review and discuss audited financial statements, reports, issues, and compliance matters. This Committee reports significant issues to the Board and makes recommendations to the independent Board members regarding the selection of the independent public accountant. More information regarding this Committee and the fund's independent auditor is found in Section C. During the 12-month period ended Sept. 30, 2005, the Board met 8 times, Executive 2 times, Contracts 7 times, Investment Review 5 times, Board Effectiveness 6 times and Joint Audit 4 times. All Board members had 100% attendance except for Mr. Simpson who had 82% attendance due to serious illness in January 2005. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 29 <Page> SHAREHOLDER COMMUNICATIONS WITH THE BOARD. Shareholders may communicate directly with the Board by sending correspondence to Arne H. Carlson, Chair of the Board, RiverSource Funds, 901 Marquette Avenue South, Suite 2810, Minneapolis, MN 55402-3268. Correspondence to specific individual Board members also may be directed to the same address. Account-specific correspondence should be directed to RiverSource Funds, 70100 Ameriprise Financial Center, Minneapolis, MN 55474. BOARD MEMBER COMPENSATION. The following table shows the total compensation received by each Board member from all of the RiverSource Funds. The funds do not pay retirement benefits to Board members.

The Board has approved, and recommends that shareholders approve, a proposal to amend the fund's articles of incorporation (the "Articles"). The fund's investments and investment policies will not change by virtue of the adoption of the amendment to the Articles. A. MINIMUM ACCOUNT VALUE. Generally, shareholders must invest at least $2,000 to open a fund account. Section 7 of the Articles currently provides that the fund may redeem shares if an account falls below a value of $1,000. Small accounts can be costly to maintain and this provision allows the Board to close accounts that no longer meet the fund's minimum standards. However, the current provision does not allow the Board to redeem accounts if the value is higher than $1,000. In the future, there may be circumstances in which a minimum account value higher than $1,000 is in the best interest of the fund and its shareholders. As a consequence, the Board recommends that the Articles be amended to eliminate the reference to a specific dollar amount. As proposed, the amended Articles will permit the Board to establish a minimum account value that will be disclosed in the fund prospectus. The Board will be able to change the minimum account value without further action by shareholders. If the change is approved, the Articles will be amended as follows (additions are [underline] underlined[/underline], [strikethrough] deletions are lined through [/strikethrough]): Article III, Section 7 will be amended to read: Section 7. The Fund may redeem the shares of a shareholder if the amount invested is less than [strikethrough] $1,000 [/strikethrough] [underline] an amount determined by the Board of Directors and set forth in the current Fund prospectus. [/underline] RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 32 <Page> B. NAME CHANGE. Historically the name of the fund has reflected the name of the investment manager. Since 1999, the name of the fund has included the letters AXP, which is an abbreviated form of the name American Express. In August 2005, American Express Financial Corporation ("AEFC"), the fund's investment manager changed its name to Ameriprise Financial, Inc. in anticipation of its spin off from American Express Company, its parent company. On Oct. 1, 2005, Ameriprise Financial transferred responsibility for the fund's investment advisory services to its wholly-owned subsidiary, RiverSource Investments. The Board made a corresponding change to the name of the fund by substituting the name RiverSource for AXP. The fund is part of a corporation made up of one fund. The name of the corporate entity can be changed only with approval of the shareholders of all the underlying funds that make up the corporation. The Board recommends that the name of the corporate entity also be changed to include the name RiverSource instead of AXP. The change to the name of the corporation is shown in the table below. This is the first shareholder meeting since the spin off of the investment manager and the first opportunity for shareholders to consider a name change for the corporation. TABLE A-5. PROPOSED NAME OF CORPORATION <Table> <Caption> CURRENT NAME OF CORPORATION PROPOSED NAME OF CORPORATION AXP Dimensions Series, Inc. RiverSource Dimensions Series, Inc </Table> BOARD RECOMMENDATION AND VOTE REQUIRED. The Board recommends that you vote to approve the amendments to the Articles. The changes require the approval by a majority of the shares voted at the meeting. The changes will be effective when the amendments are filed with the Secretary of State's office. This filing is expected to occur shortly after the shareholder meeting. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 33 <Page> PROPOSAL 4. APPROVE OR REJECT AN INVESTMENT MANAGEMENT SERVICES AGREEMENT WITH RIVERSOURCE INVESTMENTS, LLC REFERENCE TO THE "FUND" IN THIS PROPOSAL IS A REFERENCE TO NEW DIMENSIONS. The fund pays fees to RiverSource Investments under an Investment Management Services Agreement (the "IMS Agreement") for investment management services. The services include providing the personnel, equipment and office facilities necessary for the management of the fund's assets. Subject to the oversight of the Board and consistent with the fund's investment policies, the investment manager decides what securities to buy, hold or sell. The investment manager also executes buy and sell orders and provides research and statistical data to support investment management activities. INVESTMENT MANAGER. On Sept. 30, 2005, Ameriprise Financial became a publicly traded company and on Oct. 1, 2005 transferred the investment management functions and IMS Agreement to RiverSource Investments, a wholly-owned subsidiary. While these transfers did not cause a termination of the IMS Agreement, the Board determined that it would be prudent to give shareholders an opportunity to vote on the arrangement and the changes discussed below. SUMMARY OF KEY CHANGES A. PERFORMANCE INCENTIVE ADJUSTMENT ("PIA"). The management fee includes a PIA as part of the fee calculation. The PIA calculation is based on the performance of the fund compared to the performance index of a group of comparable mutual funds compiled by Lipper, Inc. ("Lipper"). The proposed change clarifies the circumstances under which the Board may change an index for purposes of calculating the PIA. B. STANDARD OF CARE. For all funds, the investment manager will be held to a higher standard of care than under the current IMS Agreement. C. CONFIDENTIALITY. The proposed IMS Agreement contains an explicit acknowledgement from the fund that the investment manager may be prevented from divulging or acting upon certain confidential information learned in connection with its activities, including the provision of investment advice to clients other than the fund. In addition, the proposed IMS Agreement contains additional confidentiality provisions prohibiting the fund from disclosing to third parties any information or advice furnished by the investment manager to the fund, except under limited circumstances. D. AMENDMENTS. The proposed IMS Agreement clarifies that, as permitted under applicable law, the parties may make non-material amendments or modifications without obtaining shareholder approval. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 34 <Page> TERMS OF THE CURRENT IMS AGREEMENT. The fee the fund pays to RiverSource Investments for its services under the current IMS Agreement is based on the net assets of the fund and decreases as the size of the fund increases. The complete fee schedule for the fund and other similar funds managed by RiverSource Investments is found in Section C. The fund also pays its taxes, brokerage commission and nonadvisory expenses, which include custodian fees; audit and certain legal fees; fidelity bond premiums; registration fees for shares; consultant fees; Board compensation; corporate filing fees; organizational expenses; expenses incurred in connection with lending portfolio securities; and other expenses properly payable by the fund, approved by the Board. Section C includes information on the date of the current IMS Agreement, the date it was last approved by shareholders and the reason why it was submitted to shareholders at that time. A. PIA CALCULATION. The management fee includes a PIA as part of the fee. The adjustment is based on the performance of the fund compared to the performance of a Lipper Index. The proposed modification does not change the IMS Agreement, but clarifies the circumstances where the Board may change the index for purposes of this calculation. The provision in the current IMS Agreement will be modified to read as follows (additions are underlined, deletions are lined through): If an Index ceases to be published for a period of more than 90 days, changes in any material respect, otherwise becomes impracticable or, in the discretion of the Board, is no longer appropriate to use for purposes of a performance incentive adjustment, for example, if Lipper reclassifies the Fund from one peer group to another, the Board may take action it deems appropriate and in the best interests of shareholders, including: (1) discontinuance of the performance incentive adjustment until such time as it approves a substitute index, or (2) adoption of a methodology to transition to a substitute index it has approved. The PIA is determined by measuring the difference in the fund's performance from an appropriate Lipper Index over a rolling 12-month period. Should the Board approve the use of a substitute index, it may transition to the substitute index by introducing it gradually over time, to avoid unintended swings in the PIA. B. STANDARD OF CARE. The proposed IMS Agreement revises the standard of care to provide that, except for bad faith, intentional misconduct or negligence in regard to the performance of its duties pursuant to the agreement, neither the investment manager, nor any of its respective directors, officers, partners, RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 35 <Page> principals, employees, or agents shall be liable for any acts or omissions or for any loss suffered by the fund or its shareholders or creditors. This means that the investment manager is held to a higher standard of care. C. CONFIDENTIALITY. The current IMS Agreement contains an acknowledgement by the fund that the investment manager renders investment advice and other services to other investment companies and persons which may or may not have investment policies and investments similar to those of the fund. The proposed IMS Agreement adds an explicit acknowledgement from the fund that the investment manager may not be free to divulge to the fund or act, for the benefit of the fund, upon confidential information learned in connection with its activities, including the provision of investment advice to clients other than the fund. The current IMS Agreement is silent on the fund's obligation to refrain from divulging confidential information. The proposed IMS Agreement includes a new provision that prohibits the fund from disclosing to third parties any information or advice furnished to the fund by the investment manager, unless required by law or necessary to provide services to the fund. D. AMENDMENTS. The current IMS Agreement does not address whether shareholder approval must be obtained before non-material amendments or modifications may be made. The proposed IMS Agreement includes a new provision clarifying that the parties may make non-material amendments or modifications without obtaining shareholder approval, as permitted under applicable law. BASIS FOR RECOMMENDATION OF THE BOARD Following announcement of the spin-off of Ameriprise Financial from American Express Company, the Board and Ameriprise Financial agreed to review and revise, where appropriate, the terms of all contracts, including the IMS Agreement, pursuant to which Ameriprise Financial or its affiliates provides services to the funds. Each year, the Board determines whether to continue the IMS Agreement for the fund and, in doing so, evaluates the quality and level of service received under the IMS Agreement and the costs associated with those services. Accordingly, in March and April of each year, Ameriprise Financial prepares detailed reports for the Board, which include data prepared by independent organizations, to assist the Board in making this determination. The Board accords considerable weight to the work, deliberations and conclusions of its committees in determining whether to continue the IMS Agreement. After thorough review of the reports and data provided at a meeting held in person on April 14, 2005, the Board, including all of its independent members, determined that the quality and level of advisory services provided pursuant to the IMS Agreement for the fund were satisfactory and that fees were fair and RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 36 <Page> reasonable. However, in light of the announced plans of the spin-off, the Board approved continuation of the IMS Agreement for only an interim period ending on the later of (i) the effective date of the spin-off; or (ii) the approval of a new investment management services agreement with Ameriprise Financial (or its subsidiary) by the shareholders of the fund, but in no event for a period longer than one year. While it was expected that the spin-off would not result in an "assignment" of an IMS Agreement under the 1940 Act and, therefore, would not cause the termination of the IMS Agreement according to its terms, Schulte Roth & Zabel LLP, retained as independent counsel to the Board, advised the Board that the legal question of whether the spin-off would result in an assignment turns on a highly fact-sensitive analysis. Therefore, the Board determined, as a matter of prudence, to proceed as if the IMS Agreement would terminate as a result of the spin-off. Accordingly, the Board determined to renew the IMS Agreement for the interim period only and to consider a new IMS Agreement for the fund prior to the spin-off. For the six months following the April 2005 meeting, the Board and its committees evaluated whether to approve a proposed IMS Agreement for the fund with post-spin Ameriprise Financial (or its subsidiary). Schulte Roth & Zabel LLP assisted the Board in fulfilling its statutory and other responsibilities associated with the spin-off and the resulting consideration of new contracts, including the proposed IMS Agreement. As a key step in this process, independent counsel sent, on behalf of the independent members of the Board, a detailed and expansive request for information to American Express Company and Ameriprise Financial, seeking specified information thought to be relevant to the Board's consideration of the proposed contracts with post-spin Ameriprise Financial. The Board and its committees were provided with a wealth of written and oral information intended to assist them in considering the proposed contracts, including the proposed IMS Agreement. Furthermore, in connection with the Board's considerations as to whether post-spin Ameriprise Financial, as an independent entity, would be capable of continuing to provide a high quality of services to the funds, the Board's independent members retained their own financial adviser, Credit Suisse First Boston LLC ("CSFB"). At the Board's requests, CSFB provided various written materials and oral presentations analyzing the capital adequacy of Ameriprise Financial. The costs of independent counsel and CSFB and of additional meetings of the Board were borne by Ameriprise Financial as part of the commitment of American Express Company to ensure a complete and thorough review of the proposed spin-off and its effect on the services provided by Ameriprise Financial and its subsidiaries. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 37 <Page> During the course of the six-month period following the April 2005 meeting, the Board and its committees met at five in-person meetings to consider the information provided by American Express Company, Ameriprise Financial, independent counsel and CSFB. At an in-person meeting held on Sept. 8, 2005, based on all of the information provided as well as the deliberations occurring at that meeting and the previous meetings held since the announcement of the spin-off, the Board, including all of its independent members, approved each of the new contracts, including the proposed IMS Agreement. On Oct. 1, 2005, pursuant to an agreement between the Fund and Ameriprise Financial, the IMS Agreement was transferred to RiverSource Investments, a wholly-owned subsidiary of Ameriprise Financial. For these reasons, the Board, including all of its independent members, recommends that you approve the proposed IMS Agreement for the fund. THE BOARD'S SPECIFIC CONSIDERATIONS RELATING TO THE PROPOSED IMS AGREEMENT. In carrying out its legal responsibilities associated with the consideration of the proposed IMS Agreement, the Board evaluated the following four factors: (i) the nature, extent and quality of services to be provided by RiverSource Investments; (ii) the investment performance of the fund; (iii) the costs of the services to be provided and the profits to be realized by Ameriprise Financial; and (iv) the extent to which economies of scale would be realized as the fund grows and whether the fee level reflects these economies of scale for the benefit of fund investors. NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE FINANCIAL (AND ITS SUBSIDIARIES). The Board recognized that only a few months had passed since its April 2005 determination to renew the IMS Agreement for the fund and that in April 2005, it had concluded that the nature, extent and quality of services provided by Ameriprise Financial were satisfactory and consistent with those that would be expected for a fund family of the size of RiverSource funds. However, the Board also recognized that this assessment must be supplemented with an evaluation of whether the spin-off or other factors would result in any changes to the advisory services currently provided to the funds. In this regard, the Board focused its evaluation on the following factors potentially impacting the nature, extent and quality of advisory services to be provided by RiverSource Investments: (i) Ameriprise Financial's projected capital structure and capital adequacy as a stand-alone entity; (ii) its legal and regulatory risks; (iii) its ability to retain and attract personnel; and (iv) its ability to successfully rebrand its products and services. Based on extensive presentations and reports by Ameriprise Financial, CSFB and independent counsel, the Board concluded that the proposed capital structure (which includes certain indemnification commitments made by American Express Company) RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 38 <Page> should enable RiverSource Investments to continue to provide a high quality of advisory services to the funds. In making this determination, the Board took into account representations by management of Ameriprise Financial that projected capital levels would allow Ameriprise Financial (including RiverSource Investments) to continue to meet its legal and compliance responsibilities, build its distribution network, pursue technological upgrades, make capital commitments necessary to retain and attract key personnel devoted to legal and compliance responsibilities, portfolio management and distribution, and pursue smaller asset management acquisitions to help grow its business. The Board accorded significant weight to CSFB's confirmation as to the reasonableness of the foregoing representations. The Board also considered the fact that there were no expected departures of key personnel involved in the portfolio management, operations and marketing of the funds as a result of the announcement of the spin-off. The Board concluded that, based on all of the materials and information provided (and with the assistance of independent counsel), post-spin Ameriprise Financial (including RiverSource Investments) would be in a position to continue to provide a high quality of investment management services to the funds. INVESTMENT PERFORMANCE. The Board next focused on investment performance. The Board reviewed reports documenting the fund's performance over one-, three- and five-year periods, as well as the entire period during which its current portfolio manager has managed the fund, and compared the performance to relevant Lipper and market indices. The Board took into account its considerations in April 2005, in particular, that investment performance in 2004 was below median, but that Ameriprise Financial has taken steps to address the underperformance. The Board also considered that it has received monthly performance reports for the funds. The Board and its committees concluded in September 2005 that there have been no significant deviations from April's overall performance data. COST OF SERVICES PROVIDED. The Board evaluated comparative fees and the costs of services to be provided under the current and proposed IMS Agreements, including fees charged by Ameriprise Financial (including RiverSource Investments and other subsidiaries) to its institutional clients and paid to subadvisers. The Board studied RiverSource Investments' effort (its "pricing philosophy") to set most funds' total expense ratios at or below the median expense ratio of their peer groups. The Board considered that the fund's management fees would not change under the proposed IMS Agreement. The Board also took into account the effect of the proposed performance incentive adjustment on the advisory fee. In this regard, the Board took into account its past determinations regarding the appropriateness of; (i) the use of the RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 39 <Page> appropriate index for the fund for the comparison of performance; (ii) the methodology for determining when the Board may change an index used to calculate the performance incentive adjustment; (iii) the periods used for averaging the fund's assets and computing investment performance; and (iv) the length of the period over which performance is computed. The Board next considered the expected profitability to RiverSource Investments and its affiliates derived from their relationships with the fund, recalling the April 2005 determination that the profitability level was appropriate. The Board noted that projected profitability of RiverSource Investments would allow it to operate effectively and, at the same time, reinvest in its businesses. The Board also considered that the proposed changes in advisory fees for certain RiverSource funds, as well as the mergers of certain RiverSource funds would result in revenue gains, while taking into account that these increases would not materially alter profit margins due to expected increases in costs associated with the spin-off, particularly rebranding and separation. CSFB also reported that Ameriprise Financial's projected level of return on equity was generally reasonable in light of the returns on equity of its industry competitors. In evaluating profitability, the Board also considered the benefits Ameriprise Financial obtains through the use of commission dollars paid on portfolio transactions for the fund and from other business relationships that result from managing the fund. The Board also considered the fees charged by Ameriprise Financial to its institutional clients and paid to subadvisers, noting the differences in services provided in each case. In light of these considerations, the Board concluded that projected profitability levels were appropriate. ECONOMIES OF SCALE. The Board also considered the breakpoints in fees that would be triggered as the net asset levels of the fund grew and the extent to which shareholders would benefit from such growth. The Board observed that the fee schedule under the proposed IMS Agreement would continue to provide breakpoints similar to those in place pursuant to the current IMS Agreement. Accordingly, the Board concluded that the proposed IMS Agreement provides adequate opportunity for shareholders to realize benefits as fund assets grow. OTHER CONSIDERATIONS. In addition, the Board accorded weight to the fact that, under the proposed IMS Agreement, RiverSource Investments is held to a higher standard of care than under the current IMS Agreement. The Board also noted Ameriprise Financial's commitment to a culture that adheres to ethical business practice, assigns accountability to senior management and seeks to identify conflicts and propose appropriate action to minimize the risks posed by the conflicts. Furthermore, the Board recognized that it was not limited to considering management's proposed contracts. In this regard, the Board RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 40 <Page> evaluated the circumstances under which it would consider the retention of an investment adviser different from RiverSource Investments (or its subsidiaries). The Board concluded, based on its consultation with independent counsel, that pursuing the retention of a different adviser was not necessary, primarily because, in its best judgment, RiverSource Investments continues to be basically the same organization (from a functional and managerial standpoint), as it was prior to the spin-off. The Board reasoned that shareholders purchased shares of the fund with an expectation that the current investment advisory organization would be servicing the fund. As a result of all of the foregoing, the Board determined that the fees to be paid under the proposed IMS Agreement were fair and reasonable in light of services proposed to be provided. BOARD RECOMMENDATION AND VOTE REQUIRED. For the foregoing reasons, the Board recommends that shareholders of the fund approve the proposed IMS Agreement. The proposed IMS Agreement must be approved by the lesser of (a) a majority of the fund's outstanding shares or (b) 67% of the shares voted at the meeting, so long as more than 50% of the shares actually vote. If shareholders approve the proposed IMS Agreement, it will take effect shortly after the shareholder meeting. If the proposed IMS Agreement is not approved, the Board will consider appropriate steps to take. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 41 <Page> SECTION B -- PROXY VOTING AND SHAREHOLDER MEETING INFORMATION REFERENCE TO THE "FUND" IN THIS SECTION IS A REFERENCE TO NEW DIMENSIONS. VOTING. You are entitled to vote based on your total dollar interest in the Fund. Each dollar is entitled to one vote. For those of you who cannot come to the meeting, the Board is asking permission to vote for you. The shares will be voted as you instruct either by mail, telephone or internet. Signed proxy cards returned without instructions will be voted in favor of all proposals. In voting for Board members, you may vote all of your shares cumulatively. This means that you have the right to give each nominee an equal number of votes or divide the votes among the nominees as you wish. You have as many votes as the number of dollars you own on the record date, multiplied by the number of Board members to be elected. If you elect to withhold authority for any individual nominee or nominees, you may do so by marking the box labeled "For All Except," and by striking the name of any excepted nominee, as is further explained on the card itself. If you do withhold authority, the proxies will not vote shares equivalent to the proportionate number applicable to the names for which authority is withheld. All votes count toward a quorum, regardless of how they are voted (For, Against or Abstain). Broker non-votes will be counted toward a quorum but not toward the approval of any proposals. (Broker non-votes are shares for which the underlying owner has not voted and the broker holding the shares does not have authority to vote.) If your shares are held in an IRA account with Ameriprise Trust Company as custodian, you have the right to instruct the IRA Custodian how to vote those shares. The IRA Custodian will vote any shares for which it has not received voting instructions in proportionately the same manner -- either For, Against, or Abstain -- as other fund shareholders have voted. MASTER/FEEDER FUNDS. New Dimensions currently is part of a master/feeder structure. The feeder fund seeks its investment objective by investing its assets in a master fund with the same policies. The master fund invests in and manages the securities. Immediately prior to the Reorganization, the Board intends to withdraw the Fund's assets from the master fund. REVOKING YOUR PROXY. If you change your mind after you vote and you can attend the meeting, simply inform the Secretary at the meeting that you will be voting your shares in person. Also, if you change your mind after you vote, but cannot attend the meeting, you may change your vote or revoke it by mail, telephone or internet. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 42 <Page> SIMULTANEOUS MEETINGS. The meeting will be held simultaneously with meetings of other RiverSource mutual funds. Each proposal will be voted on separately by shareholders of a corporation or by shareholders of a fund or by a class of shares of the fund where appropriate. If any shareholder objects to the holding of simultaneous meetings, the shareholder may move for an adjournment of his or her fund's meeting to a time immediately after the simultaneous meetings so that a meeting of that fund may be held separately. If a shareholder makes this motion, the persons named as proxies will take into consideration the reasons for the objection in deciding whether to vote in favor of the adjournment. SOLICITATION OF PROXIES. The Board is asking for your vote and for you to vote as promptly as possible. The investment manager will pay the expenses of the solicitation. Supplementary solicitations may be made by mail, telephone, electronic means or personal contact. SHAREHOLDER PROPOSALS. No proposals were received from shareholders. RiverSource funds are not required to hold regular meetings of shareholders each year. However, meetings of shareholders are held from time to time and proposals of shareholders that are intended to be presented at future shareholder meetings must be submitted in writing to RiverSource funds in reasonable time prior to the solicitation of proxies for the meeting. DISSENTERS' RIGHT OF APPRAISAL. Under Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act, Selling Fund shareholders are entitled to assert dissenters' rights in connection with the Reorganization and obtain payment of the "fair value" of their shares, provided that they comply with the requirements of Minnesota law. A copy of the relevant provisions is attached as Exhibit C. Notwithstanding the provisions of Minnesota law, the SEC has taken the position that use of state appraisal procedures by a mutual fund would be a violation of Rule 22c-1, the forward pricing rule, under the 1940 Act. This rule states that no mutual fund may redeem its shares other than at net asset value next computed after receipt of a request for redemption. It is the SEC's position that Rule 22c-1 supersedes appraisal provisions in state statutes. In the interest of ensuring equal valuation for all shareholders, dissenters' rights will be determined in accordance with the SEC's interpretation. As a result, if any shareholder elects to exercise dissenters' rights under Minnesota law, the Selling Fund intends to submit this question to a court of competent jurisdiction. In that event, a dissenting shareholder would not receive any payment until the end of the court proceeding. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT 43 <Page> OTHER BUSINESS. The Board does not know at this time of any other business to come before the meetings. If something does come up, the proxies will use their best judgment to vote for you on the matter. ADJOURNMENT. In the event that not enough votes are received by the time scheduled for the meeting, the persons named as proxies may move for one or more adjournments of the meeting for a period of not more than 120 days in the aggregate to allow further solicitation of shareholders on the proposals. Any adjournment requires the affirmative vote of a majority of the voting power of the shares present at the meeting. The persons named as proxies will vote in favor of adjournment those shares they are entitled to vote that have voted in favor of the proposal. They will vote against any adjournment those shares that have voted against the proposal. The investment manager will pay the costs of any additional solicitation and of any adjourned meeting. A shareholder vote may be taken on one or more of the items in this proxy statement prior to adjournment if sufficient votes have been received.

Ogg Vice President AXP Growth Series, Inc. on behalf of RiverSource Large Cap Equity Fund By ------------------------------------------ Leslie L. Ogg Vice President The undersigned is a party to this Agreement for purposes of Section 3c and 10 only. RiverSource Investments, LLC By ------------------------------------------ Paula R. Meyer Senior Vice President - Mutual Funds RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT A.12 <Page> EXHIBIT B MATTERS SUBJECT TO APPROVAL AT REGULAR MEETING OF BUYING FUND REFERENCE TO THE "FUND" IN THIS EXHIBIT IS A REFERENCE TO LARGE CAP EQUITY. In addition to voting on proposals to elect Board members, to amend the Articles of Incorporation and to approve the IMS Agreement, Buying Fund shareholders will consider the following: APPROVE OR REJECT CHANGES IN FUNDAMENTAL INVESTMENT POLICIES. The fund has some investment policies that are fundamental. This means the policies can be changed only with the approval of shareholders. RiverSource Investments recommended to the Board that certain of those policies be modified in order to standardize the policies for all RiverSource funds and to eliminate unnecessary limitations. RiverSource Investments believes that increased standardization will help to promote operational efficiencies and facilitate monitoring of compliance with fundamental investment policies. Adoption of a new or revised policy is not intended to change current investment techniques employed for the fund. The Board recommends the following changes to the fund's fundamental investment policies: A. DIVERSIFICATION The Board recommends that the fund's fundamental policy with respect to diversification be revised to give the fund the maximum flexibility permitted by the 1940 Act. The Board recommends that shareholders vote to replace the fund's current fundamental investment policy with the following policy (additional or revised language is underlined): The fund will not invest more than 5% of its total assets in securities of any company, government, or political subdivision thereof, except the limitation will not apply to investments in securities issued or guaranteed by the U.S. government, its agencies or instrumentalities or other investment companies, and except that up to 25% of the fund's total assets may be invested without regard to this 5% limitation. The percentage limits in the proposed policy are required under the 1940 Act. The amended policy makes one change from the current policy: subject to applicable 1940 Act requirements, it would permit the fund to invest without limit in the securities of other investment companies. Pursuant to an exemptive order granted by the Securities and Exchange Commission (the "SEC"), the fund may invest up to 25% of its total assets in a non-publicly offered money market fund managed by RiverSource RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT B.1 <Page> Investments (the "cash pool fund"). The cash pool fund is not expected to pay investment advisory, management, or transfer agent fees, although it may do so subject to the conditions of the SEC order and Board approval. The cash pool fund will incur minimal costs for services, such as custodian and auditor fees. The investment manager anticipates that making use of the cash pool fund will benefit the fund by enhancing the efficiency of cash management and by providing increased short-term investment opportunities. If the proposal is approved, the cash pool fund is expected to serve as a principal option for managing the cash positions of the fund. Future amendments to the fund's fundamental diversification policy would continue to require shareholder approval. B. LENDING The Board recommends that the fund's fundamental policies with respect to lending be replaced with the following policy: The Fund will not lend securities or participate in an interfund lending program if the total of all such loans would exceed 33 1/3% of the Fund's total assets except this fundamental investment policy shall not prohibit the Fund from purchasing money market securities, loans, loan participation or other debt securities, or from entering into repurchases agreements. Currently the fund has two policies with respect to lending. One policy limits lending of portfolio securities to 30% of net assets and the other policy limits cash loans to 5% of total assets. It is proposed that these two policies be superseded by the policy stated above. The proposal is not expected to materially affect the operation of the fund. However, the proposed policy would clarify that the fund can participate in an interfund borrowing and lending program with other RiverSource Funds, subject to the requirements of an SEC exemptive order. A fund may only borrow money for temporary purposes and may not borrow for leverage or investment purposes. Appropriate safeguards will be implemented to assure that the fund will not be disadvantaged by making loans to affiliated funds. The proposed policy also would confirm the fund's ability to invest in direct debt instruments such as loans and loan participations, which are interests in amounts owed to another party by a company, government or other borrower. These types of securities may have additional risks beyond conventional debt securities because they may provide less legal protection for the fund, or there may be a requirement that the fund supply additional cash to a borrower on demand. Finally, the adoption of the proposed investment policy will advance the goal of standardizing investment policies. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT B.2 <Page> C. BORROWING The Board recommends that the fund's fundamental policy with respect to Borrowing be replaced with the following policy: The fund may not borrow money, except for temporary purposes (not for leveraging or investment) in an amount not exceeding 33 1/3% of its total assets (including the amount borrowed) less liabilities (other than borrowings) immediately after the borrowings. Funds typically borrow money to meet redemptions in order to avoid forced, unplanned sales of portfolio securities. This technique allows RiverSource Investments greater flexibility in managing the fund's cash flow. The current policy limits borrowing to "emergency or extraordinary purposes". In order to avoid debate over what constitutes emergency or extraordinary purposes, it is proposed to revise the policy to reflect that the purposes, whatever the circumstances, must be temporary. The fund may not use borrowing for leverage or for investment purposes. BOARD RECOMMENDATION AND VOTE REQUIRED. The Board recommends that shareholders approve the proposed changes. Changes in fundamental policies must be approved by the lesser of (a) a majority of the fund's outstanding shares or (b) 67% of the shares voted at the meeting, so long as more than 50% of the shares actually vote. If the any of the proposed changes is not approved, the fund will continue to operate under its current policy. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT B.3 <Page> EXHIBIT C MINNESOTA BUSINESS CORPORATION ACT SECTIONS 302A.471 AND 302A.473 Minnesota law requires that we provide you with a copy of the state law on dissenters' rights. Notwithstanding the provisions of the law set out below, the SEC has taken the position that use of state appraisal procedures by a registered mutual fund such as the Fund would be a violation of Rule 22c-1, the forward pricing rule, under the 1940 Act. As a result, if any shareholder elects to exercise dissenters' rights under Minnesota law, the Fund intends to submit this question to a court of competent jurisdiction. In that event, a dissenting shareholder would not receive any payment until the end of the court proceeding. 302A.471. RIGHTS OF DISSENTING SHAREHOLDERS SUBDIVISION 1. ACTIONS CREATING RIGHTS. A shareholder of a corporation may dissent from, and obtain payment for the fair value of the shareholder's shares in the event of, any of the following corporate actions: (a) An amendment of the articles that materially and adversely affects the rights or preferences of the shares of the dissenting shareholder in that it: (1) alters or abolishes a preferential right of the shares; (2) creates, alters, or abolishes a right in respect of the redemption of the shares, including a provision respecting a sinking fund for the redemption or repurchase of the shares; (3) alters or abolishes a preemptive right of the holder of the shares to acquire shares, securities other than shares, or rights to purchase shares or securities other than shares; (4) excludes or limits the right of a shareholder to vote on a matter, or to cumulate votes, except as the right may be excluded or limited through the authorization or issuance of securities of an existing or new class or series with similar or different voting rights; except that an amendment to the articles of an issuing public corporation that provides that section 302A.671 does not apply to a control share acquisition does not give rise to the right to obtain payment under this section; (b) A sale, lease, transfer, or other disposition of all or substantially all of the property and assets of the corporation, but not including a transaction permitted without shareholder approval in section 302A.661, subdivision 1, or a disposition in dissolution described in section 302A.725, subdivision 2, or a disposition pursuant to an order of a court, or a disposition for cash on terms requiring that all or substantially all of the net proceeds of disposition be distributed to the shareholders in accordance with their respective interests within one year after the date of disposition; RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT C.1 <Page> (c) A plan of merger, whether under this chapter or under chapter 322B, to which the corporation is a party, except as provided in subdivision 3, and except for a plan of merger adopted under section 302A.626; (d) A plan of exchange, whether under this chapter or under chapter 322B, to which the corporation is a party as the corporation whose shares will be acquired by the acquiring corporation, except as provided in subdivision 3; or (e) Any other corporate action taken pursuant to a shareholder vote with respect to which the articles, the bylaws, or a resolution approved by the board directs that dissenting shareholders may obtain payment for their shares. SUBDIVISION 2. BENEFICIAL OWNERS. (a) A shareholder shall not assert dissenters' rights as to less than all of the shares registered in the name of the shareholder, unless the shareholder dissents with respect to all the shares that are beneficially owned by another person but registered in the name of the shareholder and discloses the name and address of each beneficial owner on whose behalf the shareholder dissents. In that event, the rights of the dissenter shall be determined as if the shares as to which the shareholder has dissented and the other shares were registered in the names of different shareholders. (b) The beneficial owner of shares who is not the shareholder may assert dissenters' rights with respect to shares held on behalf of the beneficial owner, and shall be treated as a dissenting shareholder under the terms of this section and section 302A.473, if the beneficial owner submits to the corporation at the time of or before the assertion of the rights a written consent of the shareholder. SUBDIVISION 3. RIGHTS NOT TO APPLY. (a) Unless the articles, the bylaws, or a resolution approved by the board otherwise provide, the right to obtain payment under this section does not apply to a shareholder of (1) the surviving corporation in a merger with respect to shares of the shareholder that are not entitled to be voted on the merger or (2) the corporation whose shares will be acquired by the acquiring corporation in a plan of exchange with respect to shares of the shareholder that are not entitled to be voted on the plan of exchange and are not exchanged in the plan of exchange. (b) If a date is fixed according to section 302A.445, subdivision 1, for the determination of shareholders entitled to receive notice of and to vote on an action described in subdivision 1, only shareholders as of the date fixed, and beneficial owners as of the date fixed who hold through shareholders, as provided in subdivision 2, may exercise dissenters' rights. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT C.2 <Page> SUBDIVISION 4. OTHER RIGHTS. The shareholders of a corporation who have a right under this section to obtain payment for their shares do not have a right at law or in equity to have a corporate action described in subdivision 1 set aside or rescinded, except when the corporate action is fraudulent with regard to the complaining shareholder or the corporation. 302A.473. PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS SUBDIVISION 1. DEFINITIONS. (a) For purposes of this section, the terms defined in this subdivision have the meanings given them. (b) "Corporation" means the issuer of the shares held by a dissenter before the corporate action referred to in section 302A.471, subdivision 1 or the successor by merger of that issuer. (c) "Fair value of the shares" means the value of the shares of a corporation immediately before the effective date of the corporate action referred to in section 302A.471, subdivision 1. (d) "Interest" means interest commencing five days after the effective date of the corporate action referred to in section 302A.471, subdivision 1, up to and including the date of payment, calculated at the rate provided in section 549.09 for interest on verdicts and judgments. SUBDIVISION 2. NOTICE OF ACTION. If a corporation calls a shareholder meeting at which any action described in section 302A.471, subdivision 1 is to be voted upon, the notice of the meeting shall inform each shareholder of the right to dissent and shall include a copy of section 302A.471 and this section and a brief description of the procedure to be followed under these sections. SUBDIVISION 3. NOTICE OF DISSENT. If the proposed action must be approved by the shareholders, a shareholder who is entitled to dissent under section 302A.471 and who wishes to exercise dissenters' rights must file with the corporation before the vote on the proposed action a written notice of intent to demand the fair value of the shares owned by the shareholder and must not vote the shares in favor of the proposed action. SUBDIVISION 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES. (a) After the proposed action has been approved by the board and, if necessary, the shareholders, the corporation shall send to all shareholders who have complied with subdivision 3 and to all shareholders entitled to dissent if no shareholder vote was required, a notice that contains: (1) The address to which a demand for payment and certificates of certificated shares must be sent in order to obtain payment and the date by which they must be received; (2) Any restrictions on transfer of uncertificated shares that will apply after the demand for payment is received; RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT C.3 <Page> (3) A form to be used to certify the date on which the shareholder, or the beneficial owner on whose behalf the shareholder dissents, acquired the shares or an interest in them and to demand payment; and (4) A copy of section 302A.471 and this section and a brief description of the procedures to be followed under these sections. (b) In order to receive the fair value of the shares, a dissenting shareholder must demand payment and deposit certificated shares or comply with any restrictions on transfer of uncertificated shares within 30 days after the notice required by paragraph (a) was given, but the dissenter retains all other rights of a shareholder until the proposed action takes effect. SUBDIVISION 5. PAYMENT; RETURN OF SHARES. (a) After the corporate action takes effect, or after the corporation receives a valid demand for payment, whichever is later, the corporation shall remit to each dissenting shareholder who has complied with subdivisions 3 and 4 the amount the corporation estimates to be the fair value of the shares, plus interest, accompanied by: (1) The corporation's closing balance sheet and statement of income for a fiscal year ending not more than 16 months before the effective date of the corporate action, together with the latest available interim financial statements; (2) An estimate by the corporation of the fair value of the shares and a brief description of the method used to reach the estimate; and (3) A copy of section 302A.471 and this section, and a brief description of the procedure to be followed in demanding supplemental payment. (b) The corporation may withhold the remittance described in paragraph (a) from a person who was not a shareholder on the date the action dissented from was first announced to the public or who is dissenting on behalf of a person who was not a beneficial owner on that date. If the dissenter has complied with subdivisions 3 and 4, the corporation shall forward to the dissenter the materials described in paragraph (a), a statement of the reason for withholding the remittance, and an offer to pay to the dissenter the amount listed in the materials if the dissenter agrees to accept that amount in full satisfaction. The dissenter may decline the offer and demand payment under subdivision 6. Failure to do so entitles the dissenter only to the amount offered. If the dissenter makes demand, subdivision 7 and 8 apply. (c) If the corporation fails to remit payment within 60 days of the deposit of certificates or the imposition of transfer restrictions on uncertificated shares, it shall return all deposited certificates and cancel all transfer restrictions. However, the corporation may again give notice under subdivision 4 and require deposit or restrict transfer at a later time. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT C.4 <Page> SUBDIVISION 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the amount remitted under subdivision 5 is less than the fair value of the shares plus interest, the dissenter may give written notice to the corporation of the dissenter's own estimate of the fair value of the shares, plus interest, within 30 days after the corporation mails the remittance under subdivision 5, and demand payment of the difference. Otherwise, a dissenter is entitled only to the amount remitted by the corporation. SUBDIVISION 7. PETITION; DETERMINATION. If the corporation receives a demand under subdivision 6, it shall, within 60 days after receiving the demand, either pay to the dissenter the amount demanded or agreed to by the dissenter after discussion with the corporation or file in a court a petition requesting that the court determine the fair value of the shares, plus interest. The petition shall be filed in the county in which the registered office of the corporation is located, except that a surviving foreign corporation that receives a demand relating to the shares of a constituent domestic corporation shall file the petition in the county in this state in which the last registered office of the constituent corporation was located. The petition shall name as parties all dissenters who have demanded payment under subdivision 6 and who have not reached agreement with the corporation. The corporation shall, after filing the petition, serve all parties with a summons and copy of the petition under the rules of civil procedure. Nonresidents of this state may be served by registered or certified mail or by publication as provided by law. Except as otherwise provided, the rules of civil procedures apply to this proceeding. The jurisdiction of the court is plenary and exclusive. The court may appoint appraisers, with powers and authorities the court deems proper, to receive evidence on and recommend the amount of the fair value of the shares. The court shall determine whether the shareholder or shareholders in question have fully complied with the requirements of this section, and shall determine the fair value of the shares, taking into account any and all factors the court finds relevant, computed by any method or combination of methods that the court, in its discretion, sees fit to use, whether or not used by the corporation or by a dissenter. The fair value of the shares as determined by the court is binding on all shareholders, wherever located. A dissenter is entitled to judgment in cash for the amount by which the fair value of the shares as determined by the court, plus interest, exceeds the amount, if any, remitted under subdivision 5, but shall not be liable to the corporation for the amount, if any, by which the amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair value of the shares as determined by the court, plus interest. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT C.5 <Page> SUBDIVISION 8. COSTS; FEES; EXPENSES. (a) The court shall determine the costs and expenses of a proceeding under subdivision 7, including the reasonable expenses and compensation of any appraisers appointed by the court, and shall assess those costs and expenses against the corporation, except that the court may assess part or all of those costs and expenses against a dissenter whose action in demanding payment under subdivision 6 is found to be arbitrary, vexatious, or not in good faith. (b) If the court finds that the corporation has failed to comply substantially with this section, the court may assess all fees and expenses of any experts or attorneys as the court deems equitable. These fees and expenses may also be assessed against a person who has acted arbitrarily, vexatiously, or not in good faith in bringing the proceeding, and may be awarded to a party injured by those actions. (c) The court may award, in its discretion, fees and expenses to an attorney for the dissenters out of the amount awarded to the dissenters, if any.

(Ameriprise Financial) (formerly American Express Financial Corporation) was spun off to shareholders of its parent corporation, American Express Company (American Express), and is now a separate public company, trading under the ticker symbol AMP. Ameriprise Financial provides administrative services to the Fund and is the parent company of the Fund's investment manager, RiverSource Investments, LLC; the Fund's distributor, Ameriprise Financial Services, Inc. (formerly American Express Financial Advisors Inc.); the Fund's transfer agent, RiverSource Service Corporation (formerly American Express Client Service Corporation); and the Fund's custodian, Ameriprise Trust Company (formerly American Express Trust Company). On Oct. 1, 2005, the Fund changed its name, such that it no longer is branded AXP(R). The Fund now bears the RiverSource(SM) brand. Ameriprise Financial and its subsidiaries are no longer affiliated with American Express. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.2 <Page> THE FUND OBJECTIVE RiverSource Large Cap Equity Fund (the Fund) seeks to provide shareholders with long-term growth of capital. Because any investment involves risk, achieving this objective cannot be guaranteed. PRINCIPAL INVESTMENT STRATEGIES Under normal market conditions, at least 80% of the Fund's net assets are invested in equity securities of companies with a market capitalization greater than $5 billion at the time of purchase. The Fund may invest in income-producing equity securities, such as dividend paying stocks, convertible securities and preferred stocks. The Fund will provide shareholders with at least 60 days' notice of any change in the 80% policy. In pursuit of the Fund's objective, the investment manager (RiverSource Investments, LLC) will hold both growth and value companies and at times may favor one more than the other based on available opportunities. When optimizing for growth, the investment manager invests in companies it believes to have above-average long-term growth potential, or technological superiority, and it selects investments based, among other factors, on: - Effective management. - Financial strength. - Competitive market or product position. - Technological advantage relative to other companies. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.3 <Page> When optimizing for value, the investment manager invests in companies that appear to be undervalued by various measures or that may be temporarily out of favor, but have good prospects for capital appreciation, and it selects investments based, among other factors, on: - - Identifying a variety of large, well-established companies whose underlying fundamentals are stable, or are anticipated to become stable, or whose fundamentals are improving. - - Identifying stocks that are undervalued: - because they have one or more ratios, such as price-to-earnings or price-to-cash flow, that are low relative to the general market, or have a yield that exceeds the market, - because one or more of their valuation ratios are low relative to historical levels for the stock, - because one or more of their valuation ratios or other financial measures make that stock attractive relative to its peers, or - because they are undervalued relative to their intrinsic value, as identified by the investment manager. In evaluating whether to sell a security, the investment manager considers factors including, among others whether: - - The security is overvalued relative to other potential investments. - - The security has reached the investment manager's price objective. - - The company has met the investment manager's earnings and/or growth expectations. - - Potential losses, due to factors such as a market down-turn, can be minimized. - - A more attractive opportunity has been identified. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.4 <Page> PRINCIPAL RISKS Please remember that with any mutual fund investment you may lose money. Principal risks associated with an investment in the Fund include: ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance therefore will reflect in part the ability of the portfolio managers to make investment decisions that are suited to achieving the Fund's investment objective. Due to its active management, the Fund could underperform other mutual funds with similar investment objectives. ISSUER RISK. An issuer may perform poorly, and therefore, the value of its stocks and bonds may decline. Poor performance may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, or other factors. MARKET RISK. The market value of securities may fall or fail to rise. Market risk may affect a single issuer, sector of the economy, industry, or the market as a whole. The market value of securities may fluctuate, sometimes rapidly and unpredictably. This risk is generally greater for small and mid-sized companies, which tend to be more vulnerable to adverse developments. In addition, focus on a particular style, for example, investment in growth or value securities, may cause the Fund to underperform other mutual funds if that style falls out of favor with the market. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.5 <Page> PAST PERFORMANCE The following bar chart and table provide some illustration of the risks of investing in the Fund by showing, respectively: - - how the Fund's performance has varied for each full calendar year shown on the bar chart, and - - how the Fund's average annual total returns compare to recognized indexes shown on the table. Both the bar chart and the table assume that all distributions have been reinvested. The performance of different classes varies because of differences in sales charges and other fees and expenses. How the Fund has performed in the past (before and after taxes) does not indicate how the Fund will perform in the future. Performance reflects any fee waivers/expense caps in effect for the periods reported. In the absence of such fee waivers/expense caps, performance would have been lower. See "Fees and Expenses" for any current fee waivers/expense caps. BAR CHART. Class A share information is shown in the bar chart; the sales charge for Class A shares is not reflected in the bar chart. TABLE. The table shows total returns from hypothetical investments in Class A, Class B, Class C and Class Y shares of the Fund. These returns are compared to the indexes shown for the same periods. For purposes of the performance calculation in the table we assumed: - - the maximum sales charge for Class A shares, - - sales at the end of the period and deduction of the applicable contingent deferred sales charge (CDSC) for Class B and Class C shares, - - no sales charge for Class Y shares, and - - no adjustments for taxes paid by an investor on the reinvested income and capital gains. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.6 <Page> AFTER-TAX RETURNS After-tax returns are shown only for Class A shares. After-tax returns for the other classes will vary. After-tax returns are calculated using the highest historical individual federal marginal income tax rate and do not reflect the impact of state and local taxes. Actual after-tax returns will depend on your tax situation and most likely will differ from the returns shown in the table. If you hold your shares in a tax-deferred account, such as a 401(k) plan or an IRA, the after-tax returns do not apply to you since you will not incur taxes until you begin to withdraw from your account. The return after taxes on distributions for a period may be the same as the return before taxes for the same period if there were no distributions or if the distributions were small. The return after taxes on distributions and sale of Fund shares for a period may be greater than the return before taxes for the same period if there was a tax loss realized on sale of Fund shares. The benefit of the tax loss (since it can be used to offset other gains) may result in a higher return. [CHART] CLASS A SHARE PERFORMANCE (BASED ON CALENDAR YEARS) <Table> +27.57 +5.52 2003 2004 </Table> During the periods shown in the bar chart, the highest return for a calendar quarter was +16.15% (quarter ended June 30, 2003) and the lowest return for a calendar quarter was -4.93% (quarter ended Sept. 30, 2004). The 5.75% sales charge applicable to Class A shares of the Fund is not reflected in the bar chart; if reflected, returns would be lower than those shown. The performance of other classes may vary from that shown because of differences in expenses. The Fund's Class A year-to-date return at June 30, 2005 was +1.59%. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.7 <Page> AVERAGE ANNUAL TOTAL RETURNS (FOR PERIODS ENDED DEC. 31, 2004) <Table> <Caption> SINCE 1 YEAR INCEPTION RiverSource Large Cap Equity: Class A Return before taxes -0.55% +0.02%(a) Return after taxes on distributions -1.55% -0.55%(a) Return after taxes on distributions and sale of fund shares -0.29% -0.29%(a) Class B Return before taxes -0.27% -0.09%(a) Class C Return before taxes +3.72% +1.40%(a) Class Y Return before taxes +5.63% +2.32%(a) Russell 1000(R)Index (reflects no deduction for fees, expenses or taxes) +11.40% +4.39%(b) Lipper Large-Cap Core Funds Index +8.29% +2.27%(b) </Table> (a) Inception date is March 28, 2002. (b) Measurement period started April 1, 2002. The Russell 1000(R) Index, an unmanaged index, measures the performance of the 1,000 largest companies in the Russell 3000 Index, and represents approximately 92% of the total market capitalization of the Russell 3000 Index. The Lipper Large-Cap Core Funds Index includes the 30 largest large-cap core funds tracked by Lipper Inc. The index's returns include net reinvested dividends. The Fund's performance is currently measured against this index for purposes of determining the performance incentive adjustment. See "Fund Management and Compensation" for more information.

The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Expenses are based on the Fund's most recent fiscal year, adjusted to reflect current fees.

(d) Other expenses include an administrative services fee, a transfer agency fee, a custody fee and other nonadvisory expenses and, for Class Y shares, a shareholder service fee. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.9 <Page> EXAMPLES These examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. These examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. These examples also assume that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: <Table> <Caption> 1 YEAR 3 YEARS 5 YEARS 10 YEARS Class A(a) $688 $ 928 $1,188 $1,929 Class B $698(b) $1,013(b) $1,253(b) $2,079(c) Class C $298(b) $ 613 $1,053 $2,280 Class Y $ 99 $ 309 $ 537 $1,194 </Table> (a) Includes a 5.75% sales charge.

(b) Based on conversion of Class B shares to Class A shares in the ninth year of ownership. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.10 <Page> OTHER INVESTMENT STRATEGIES AND RISKS OTHER INVESTMENT STRATEGIES. In addition to the principal investment strategies previously described, the Fund may invest in other securities and may use other investment strategies that are not principal investment strategies. Additionally, the Fund may use derivatives (financial instruments where the value depends upon, or is derived from, the value of something else) such as futures, options and forward contracts, to produce incremental earnings, to hedge existing positions or to increase flexibility. Just as with securities in which the Fund invests directly, derivatives are subject to a number of risks, including market, liquidity, interest rate and credit risk. In addition, a relatively small price movement in the underlying security, currency or index may result in a substantial gain or loss for the Fund using derivatives. Even though the Fund's policies permit the use of derivatives in this manner, the portfolio managers are not required to use derivatives. For more information on strategies and holdings, and the risks of such strategies, including other derivative instruments that the Fund may use, see the Fund's Statement of Additional Information (SAI) and its annual and semiannual reports. UNUSUAL MARKET CONDITIONS. During unusual market conditions, the Fund may temporarily invest more of its assets in money market securities than during normal market conditions. Although investing in these securities would serve primarily to avoid losses, this type of investing also could prevent the Fund from achieving its investment objective. During these times, the portfolio managers may make frequent securities trades that could result in increased fees, expenses and taxes, and decreased performance. PORTFOLIO TURNOVER. Trading of securities may produce capital gains, which are taxable to shareholders when distributed. Active trading may also increase the amount of commissions or mark-ups paid to broker-dealers that the Fund pays when it buys and sells securities. The Fund's historical portfolio turnover rate, which measures how frequently the Fund buys and sells investments, is shown in the "Financial Highlights." RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.11 <Page> SECURITIES TRANSACTION COMMISSIONS. Securities transactions involve the payment by the Fund of brokerage commissions to broker-dealers, on occasion as compensation for research or brokerage services (commonly referred to as "soft dollars"), as the portfolio managers buy and sell securities for the Fund in pursuit of its objective. A description of the policies governing the Fund's securities transactions and the dollar value of brokerage commissions paid by the Fund are set forth in the SAI. The brokerage commissions set forth in the SAI do not include implied commissions or mark-ups (implied commissions) paid by the Fund for principal transactions (transactions made directly with a dealer or other counterparty), including most fixed income securities and certain derivatives. In addition, brokerage commissions do not reflect other elements of transaction costs, including the extent to which the Fund's purchase and sale transactions may cause the market to move and change the market price for an investment. Although brokerage commissions and implied commissions are not reflected in the expense table under "Fees and Expenses," they are reflected in the total return of the Fund. DIRECTED BROKERAGE. The Fund's Board of Directors (Board) has adopted a policy prohibiting the investment manager, or any subadviser, from considering sales of shares of the Fund as a factor in the selection of broker-dealers through which to execute securities transactions. Additional information regarding securities transactions can be found in the SAI. FUND MANAGEMENT AND COMPENSATION INVESTMENT MANAGER RiverSource Investments, LLC (the investment manager or RiverSource Investments), 200 Ameriprise Financial Center, Minneapolis, Minnesota 55474, is the investment manager to the RiverSource funds, and is a wholly owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Ameriprise Financial is a financial planning and financial services company that has been offering solutions for clients' asset accumulation, income management and protection needs for more than 110 years. In addition to managing investments for all of the RiverSource funds, RiverSource Investments manages investments for itself and its affiliates. For institutional clients, RiverSource Investments and its affiliates provide investment management and related services, such as separate account asset management, institutional trust and custody, and employee benefit plan administration, as well as other investment products. For all of its clients, RiverSource Investments seeks to allocate investment opportunities in an equitable manner over time. See the SAI for more information. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.12 <Page> The Fund pays RiverSource Investments a fee for managing its assets. Under the Investment Management Services Agreement (Agreement), the fee for the most recent fiscal year was 0.57% of the Fund's average daily net assets, including an adjustment under the terms of a performance incentive arrangement. The adjustment is computed by comparing the Fund's performance to the performance of an index of comparable funds published by Lipper Inc. The index against which the Fund's performance is currently measured for purposes of the performance incentive adjustment is the Lipper Large-Cap Core Funds Index. In certain circumstances, the Fund's Board may approve a change in the index. The maximum adjustment (increase or decrease) is 0.12% of the Fund's average net assets on an annual basis. Under the Agreement, the Fund also pays taxes, brokerage commissions, and nonadvisory expenses. A discussion regarding the basis for the Board approving the Agreement is available in the Fund's most recent shareholder report. PORTFOLIO MANAGER(S). The portfolio managers responsible for the day-to-day management of the Fund are: Robert Ewing, CFA, Portfolio Manager - - Managed the Fund since 2004. - - Joined RiverSource Investments (previously American Express Financial Corporation (AEFC)) in 2002. - - Prior to that, Analyst and Portfolio Manager at Fidelity Investments from 1990 to 2002. - - Began investment career in 1988. - - BS, Boston College Carroll School of Management. Nick Thakore, Portfolio Manager - - Managed the Fund since 2004. - - Joined RiverSource Investments (previously AEFC) in 2002. - - Prior to that, Analyst and Portfolio Manager at Fidelity Investments from 1993 to 2002. - - Began investment career in 1993. - - MBA, Wharton School at University of Pennsylvania. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.13 <Page> Mr. Thakore provides direct day-to-day management for approximately one-third of the portfolio optimizing for growth. Mr. Ewing provides direct day-to-day management for approximately one-third of the portfolio optimizing for value. Messrs. Ewing and Thakore coordinate day-to-day management of the remainder of the portfolio, allocating approximately one-third of the portfolio among a team of research analysts who select investments in their allocations based on the sectors that they cover. These allocations are generally consistent with the sector weightings of the S&P 500 Index, an unmanaged index of common stocks, but allocations may vary. The SAI provides additional information about portfolio manager compensation, management of other accounts and ownership of shares in the Fund. ADDITIONAL SERVICES AND COMPENSATION As described above, RiverSource Investments receives compensation for acting as the Fund's investment manager. RiverSource Investments and its affiliates also receive compensation for providing other services to the Fund. ADMINISTRATION SERVICES. Ameriprise Financial, 200 Ameriprise Financial Center, Minneapolis, Minnesota 55474, provides or compensates others to provide administrative services to the RiverSource funds. These services include administrative, accounting, treasury, and other services. Fees paid by the Fund for these services are included under "Other expenses" in the expense table under "Fees and Expenses." CUSTODY SERVICES. Ameriprise Trust Company, 200 Ameriprise Financial Center, Minneapolis, Minnesota 55474 (the custodian or Ameriprise Trust Company), provides custody services to all but a limited number of the RiverSource funds, for which U.S. Bank National Association provides custody services. In addition, Ameriprise Trust Company is paid for certain transaction fees and out-of-pocket expenses incurred while providing services to the funds. Fees paid by the Fund for these services are included under "Other expenses" in the expense table under "Fees and Expenses." DISTRIBUTION SERVICES. Ameriprise Financial Services, Inc., 70100 Ameriprise Financial Center, Minneapolis, Minnesota 55474 (the distributor or Ameriprise Financial Services), provides underwriting and distribution services to the RiverSource funds. Under the Distribution Agreement and related distribution and shareholder servicing plan(s), the distributor receives distribution and shareholder servicing fees. The distributor pays a portion of these fees to financial advisors and retains a portion of these fees to support its distribution and shareholder servicing activity. For third party sales, the distributor re-allows a portion of these fees to the financial intermediaries that sell Fund shares and provide services to shareholders, and retains a portion of these fees to support its distribution and shareholder servicing activity. Fees paid by the Fund for RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.14 <Page> these services are set forth under "Distribution (12b-1) fees" in the expense table under "Fees and Expenses." More information on how these fees are used is set forth under "Investment Options" and in the SAI. The distributor also administers any sales charges paid by an investor at the time of purchase or at the time of sale (deferred sales charge). See "Shareholder Fees (fees paid directly from your investment)" under "Fees and Expenses" for the scheduled sales charge of each share class. See "Buying and Selling Shares" for variations in the scheduled sales charges, and for how these sales charges are used by the distributor. See "Other Investment Strategies and Risks" for Fund policy regarding directed brokerage. TRANSFER AGENCY SERVICES. RiverSource Service Corporation, 70100 Ameriprise Financial Center, Minneapolis, Minnesota 55474 (the transfer agent or RiverSource Service Corporation), provides or compensates others to provide transfer agency services to the RiverSource funds. The RiverSource funds pay the transfer agent a fee, which varies by share class, as set forth in the SAI and reimburses the transfer agent for its out-of-pocket expenses incurred while providing these transfer agency services to the funds. Fees paid by the Fund for these services are included under "Other expenses" in the expense table under "Fees and Expenses." RiverSource funds are primarily sold through Ameriprise Financial Services which is allocated a portion of these fees for providing services to Fund shareholders. RiverSource Service Corporation may also pay a portion of these fees to other financial intermediaries that provide sub-recordkeeping and other services to Fund shareholders. The SAI provides additional information about the services provided and the fee schedules for the agreements set forth above. PAYMENTS TO FINANCIAL INTERMEDIARIES RiverSource Investments and its affiliates may make additional cash payments out of their own resources to financial intermediaries, such as broker-dealers, banks, qualified plan administrators and recordkeepers, or other institutions, including inter-company allocation of resources to affiliated broker-dealers such as Ameriprise Financial Services (financial intermediaries) in connection with the sale of shares of the Fund and/or the provision of services to the Fund or its shareholders. These payments may create an incentive for the financial intermediary, its employees or registered representatives to recommend or sell shares of the Fund to its customers. These payments and inter-company allocations are in addition to any 12b-1 distribution and/or shareholder service fees or other amounts paid by the Fund under distribution or shareholder servicing plans, or paid by the Fund for shareholder account maintenance, sub-accounting or recordkeeping services provided directly by the financial intermediary providing such services. In exchange for these cash payments and RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.15 <Page> inter-company allocations, RiverSource Investments and its affiliates may receive preferred access to registered representatives of a financial intermediary (for example, the ability to make presentations in branch offices or at conferences) or preferred access to customers of the financial intermediary (for example, the ability to advertise or directly interact with the financial intermediary's customers in order to sell the Fund). These arrangements are sometimes referred to as "revenue sharing payments." In some cases, these arrangements may create an incentive for a financial intermediary or its representatives to recommend or sell shares of a fund and may create a conflict of interest between a financial intermediary's financial interest and its duties to its customers. Please contact the financial intermediary through which you are purchasing shares of the Fund for details about any payments it may receive in connection with the sale of Fund shares or the provision of services to the Fund. These payments and inter-company allocations are usually calculated based on a percentage of fund sales, and/or as a percentage of fund assets attributable to a particular financial intermediary. These payments may also be negotiated based on other criteria or factors including, but not limited to, the financial intermediary's affiliation with the investment manager, its reputation in the industry, its ability to attract and retain assets, its access to target markets, its customer relationships and the scope and quality of services it provides. The amount of payment or inter-company allocation may vary by financial intermediary and by type of sale (e.g. purchases of different share classes or purchases of the Fund through a qualified plan or through a wrap program) and may be significant. From time to time, RiverSource Investments and its affiliates may make other payments, including non-cash compensation, to financial intermediaries to the extent permitted by law, including providing non-cash compensation to financial intermediaries or their representatives in the form of gifts of nominal value, occasional meals, tickets, or other entertainment, support for due diligence trips, training and educational meetings, or conference sponsorships, support for recognition programs, and other forms of non-cash compensation permissible under regulations to which these financial intermediaries and their representatives are subject. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.16 <Page> ADDITIONAL MANAGEMENT INFORMATION MANAGER OF MANAGER EXEMPTION. The Fund operates under an order from the Securities and Exchange Commission that permits RiverSource Investments, subject to the approval of the Board, to appoint a subadviser or change the terms of a subadvisory agreement for the Fund without first obtaining shareholder approval. The order permits the Fund to add or change unaffiliated subadvisers or the fees paid to subadvisers from time to time without the expense and delays associated with obtaining shareholder approval of the change. AFFILIATED FUNDS-OF-FUNDS. RiverSource Investments also serves as investment manager to the RiverSource Portfolio Builder Funds (Portfolio Builder Funds), a group of six funds-of-funds that provide asset-allocation services to shareholders by investing in shares of other RiverSource funds, including the Fund. The Fund may experience relatively large purchases or redemptions from the Portfolio Builder Funds. Although RiverSource Investments seeks to minimize the impact of these transactions by structuring them over a reasonable period of time, the Fund may experience increased expenses as it buys and sells securities to manage transactions for the Portfolio Builder Funds. In addition, because the Portfolio Builder Funds may own a substantial portion of the Fund, a redemption by the Portfolio Builder Funds could cause the Fund's expense ratio to increase as the Fund's fixed costs would be spread over a smaller asset base. RiverSource Investments monitors expense levels and is committed to offering funds that are competitively priced. RiverSource Investments will report to the Fund's Board on the steps it has taken to manage any potential conflicts. FUND HOLDINGS DISCLOSURE. The Fund's Board has adopted policies and procedures that govern the timing and circumstances of disclosure to shareholders and third parties of information regarding the securities owned by the Fund. A description of these policies and procedures is included in the Fund's SAI. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.17 <Page> BUYING AND SELLING SHARES TRANSACTIONS THROUGH UNAFFILIATED FINANCIAL INTERMEDIARIES Where authorized by the distributor, shares of the Fund may be available through certain 401(k) or other qualified plans, banks, broker-dealers or other institutions (financial intermediaries). These financial intermediaries may charge you additional fees for the services they provide and they may have different policies not described in this prospectus. Some policy differences may include different minimum investment amounts, exchange privileges, fund choices and cutoff times for investments. Additionally, recordkeeping, transaction processing and payments of distributions relating to your account may be performed by the financial intermediaries or their representatives through whom shares are held. Since the Fund may not have a record of your transactions, you should always contact the financial intermediary through whom you purchased the Fund to make changes to or give instructions concerning your account or to obtain information about your account. The Fund and the distributor are not responsible for the failure of one of these financial intermediaries to carry out its obligations to its customers. AVAILABILITY AND TRANSFERABILITY OF FUND SHARES. Please consult your investment professional or financial intermediary to determine availability of the Fund. Currently, RiverSource funds may be purchased or sold through affiliated broker-dealers of RiverSource Investments, including Ameriprise Financial Services and Securities America, Inc. (Securities America), and through a limited number of unaffiliated institutions. If you set up an account at another financial intermediary, you will not be able to transfer RiverSource fund holdings to that account unless that institution has obtained a selling agreement with the distributor of the RiverSource funds. If you set up an account with an unaffiliated financial intermediary that does not have, and is unable to obtain, such a selling agreement, you must either maintain your position with Ameriprise Financial Services or Securities America, find another financial intermediary with such a selling agreement, or sell your shares, paying any applicable deferred sales charge. Please be aware that transactions in taxable accounts would generate a taxable event and may result in an increased income tax liability. For more information, please call RiverSource Service Corporation at (888) 791-3380. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.18 <Page> The public offering price for Class A shares of the Fund is the net asset value (NAV) plus a sales charge, and for Class B, C, and Y shares, the NAV. Orders in good form are priced at the NAV next determined after you place your order. Good form or good order means that your instructions have been received in the form required by the distributor. This may include, for example, providing the fund name and account number, the amount of the transaction and all required signatures. For more information, refer to the sections on "Purchasing Shares" and "Exchanging/Selling Shares," or contact your financial advisor or investment professional. If you buy or sell shares through an authorized financial intermediary, consult that firm to determine its procedures for accepting and processing orders. The financial intermediary may charge a fee for its services. VALUING FUND SHARES The NAV is the value of a single share of the Fund. The NAV is determined by dividing the value of the Fund's assets, minus any liabilities, by the number of shares outstanding. The NAV is calculated as of the close of business on the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time, on each day that the NYSE is open. The Fund's securities are valued primarily on the basis of market quotations obtained from outside pricing services approved and monitored under procedures adopted by the Board. Certain short-term securities with maturities of 60 days or less are valued at amortized cost. When reliable market quotations are not readily available, securities are priced at fair value based on procedures adopted by the Board. These procedures are also used when the value of a security held by the Fund is materially affected by events that occur after the close of the primary market on which the security is traded but prior to the time as of which the Fund's NAV is determined. Valuing securities at fair value involves reliance on judgment. The fair value of a security is likely to differ from any available quoted or published price. Foreign investments are valued in U.S. dollars. Some of the Fund's securities may be listed on foreign exchanges that trade on weekends or other days when the Fund does not price its shares. In that event, the NAV of the Fund's shares may change on days when shareholders will not be able to purchase or sell the Fund's shares. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.19 <Page> INVESTMENT OPTIONS 1. CLASS A shares are sold to the public with a sales charge at the time of purchase and an annual distribution and shareholder servicing (12b-1) fee of 0.25%. 2. CLASS B shares are sold to the public with a contingent deferred sales charge (CDSC) and an annual distribution and shareholder servicing (12b-1) fee of 1.00%. 3. CLASS C shares are sold to the public without a sales charge at the time of purchase and with an annual distribution and shareholder servicing (12b-1) fee of 1.00%. Class C shares redeemed within than one year after purchase may be subject to a CDSC. 4. CLASS Y shares are sold to qualifying institutional investors without a sales charge or distribution fee, but with a separate shareholder servicing fee of 0.10%. Please see the SAI for information on eligibility requirements to purchase Class Y shares. The distribution and shareholder servicing fees for Class A, Class B and Class C shares are subject to the requirements of Rule 12b-1 under the Investment Company Act of 1940, as amended, and are used to reimburse the distributor for certain expenses it incurs in connection with distributing the Fund's shares and providing services to Fund shareholders. These expenses include payment of distribution and shareholder servicing fees to financial intermediaries that sell shares of the Fund. Financial intermediaries receive shareholder servicing fees equal to 0.25% of the average daily net assets of Class A, Class B and Class C shares sold and held through them. For Class A and Class B shares, the distributor begins to pay these fees immediately after purchase. For Class C shares, the distributor begins to pay these fees one year after purchase. Financial intermediaries also receive distribution fees equal to 0.75% of the average daily net assets of Class C shares sold and held through them, which the distributor begins to pay one year after purchase. For Class B shares, the Fund's distributor retains the 0.75% distribution fee in order to finance the payment of sales commissions to financial intermediaries that sell Class B shares, and to pay for other distribution related expenses. Financial intermediaries may compensate their financial advisors and investment professionals with the shareholder servicing and distribution fees paid to them by the distributor. The shareholder servicing fees for Class Y shares are used to reimburse the distributor for providing services and assistance to shareholders regarding ownership of their shares or their accounts. The Fund also offers an additional class of shares, Class I, exclusively to certain institutional investors. Class I shares are made available through a separate prospectus supplement provided to investors eligible to purchase the shares. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.20 <Page> INVESTMENT OPTIONS SUMMARY The Fund offers different classes of shares. There are differences among the fees and expenses for each class. Not everyone is eligible to buy every class. After determining which classes you are eligible to buy, decide which class best suits your needs. Your financial advisor or investment professional can help you with this decision. The following table shows the key features of each class: <Table> <Caption> CLASS A CLASS B CLASS C CLASS Y - ----------------------------------------------------------------------------------------------------------------------------- AVAILABILITY Available to all Available to all Available to all Limited to qualifying investors. investors. investors. institutional investors.

The Fund has also adopted a separate shareholder servicing plan to pay for servicing-related expenses related to Class Y shares. Because these fees are paid out of the Fund's assets on an on-going basis, over time, these fees will increase the cost of your investment and may cost you more than paying other types of distribution (sales) or servicing charges. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.21 <Page> SHOULD YOU PURCHASE CLASS A, CLASS B OR CLASS C SHARES? If your investments in RiverSource funds total $100,000 or more, Class A shares may be the better option because the sales charge is reduced for larger purchases. If you qualify for a waiver of the sales charge, Class A shares will be the best option. If you invest less than $100,000, consider how long you plan to hold your shares. Class B shares have a higher annual distribution fee than Class A shares and a CDSC for six years. Class B shares convert to Class A shares in the ninth year of ownership. Class B shares purchased through reinvested dividends and distributions also will convert to Class A shares in the same proportion as the other Class B shares. Class C shares also have a higher annual distribution fee than Class A shares. Class C shares have no sales charge if you hold the shares for longer than one year. Unlike Class B shares, Class C shares do not convert to Class A. As a result, you will pay a 1% distribution fee for as long as you hold Class C shares. If you choose a deferred sales charge option (Class B or Class C), you should consider the length of time you intend to hold your shares. To help you determine which investment is best for you, consult your financial advisor or investment professional. For more information, see the SAI. PURCHASING SHARES Financial intermediaries are required by law to obtain certain personal information from each person who opens an account in order to verify the identity of the person. As a result, when you open an account you will be asked to provide your name, permanent street address, date of birth, and Social Security or Employer Identification number. You may also be asked for other identifying documents or information. If you do not provide this information, the Fund, or the financial intermediary through which you are investing in the Fund, may not be able to open an account for you. If the Fund or if the financial intermediary through which you are investing in the Fund is unable to verify your identity, your account may be closed, or other steps may be taken, as deemed appropriate. TO PURCHASE SHARES WITH A FINANCIAL INTERMEDIARY OTHER THAN AMERIPRISE FINANCIAL SERVICES, PLEASE CONSULT YOUR FINANCIAL INTERMEDIARY.

When you purchase, your order will be priced at the next NAV calculated after your order is accepted by the Fund. If your application does not specify which class of shares you are purchasing, we will assume you are investing in Class A shares. IMPORTANT: When you open an account, you must provide your correct Taxpayer Identification Number (TIN), which is either your Social Security or Employer Identification number. If you do not provide and certify the correct TIN, you could be subject to backup withholding of 28% of taxable distributions and proceeds from certain sales and exchanges. You also could be subject to further penalties, such as: - - a $50 penalty for each failure to supply your correct TIN, - - a civil penalty of $500 if you make a false statement that results in no backup withholding, and - - criminal penalties for falsifying information. You also could be subject to backup withholding, if the IRS notifies us to do so, because you failed to report required interest or dividends on your tax return.

RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.25 <Page> RIGHTS OF ACCUMULATION YOU MAY BE ABLE TO REDUCE THE SALES CHARGE ON CLASS A SHARES, BASED ON THE COMBINED MARKET VALUE OF YOUR ACCOUNTS. The current market values of the following investments are eligible to be added together for purposes of determining the sales charge on your purchase: - - Your current investment in this Fund, and - - Previous investments you and members of your primary household group have made in Class A, Class B or Class C shares in this and other RiverSource funds, provided your investment was subject to a sales charge. - Your primary household group consists of you, your spouse or domestic partner, and your unmarried children under age 21 sharing a mailing address. For purposes of this policy a domestic partner is an individual who shares your primary residence and with whom you own joint property. If you or any member of your primary household group elects to separate from the primary household group (for example, by asking that account statements be sent to separate addresses), your assets will no longer be combined for purposes of reducing your sales charge. The following accounts are eligible to be included in determining the sales charge on your purchase: - - Individual or joint accounts held outside of a brokerage account; - - Individual or joint accounts held through a brokerage account; - - Roth and traditional IRAs, SEPs, SIMPLEs and TSCAs, provided they are invested in Class A, Class B or Class C shares that are subject to a sales charge; - - UGMA/UTMA accounts for which you, your spouse, or your domestic partner is parent or guardian of the minor child; - - Revocable trust accounts for which you or a member of your primary household group, individually, is the beneficiary; - - Accounts held in the name of your, your spouse's, or your domestic partner's sole proprietorship or single owner limited liability company or S corporation; and - - Qualified retirement plan assets, provided that you are the sole owner of the business sponsoring the plan, are the sole participant (other than a spouse) in the plan, and have no intention of adding participants to the plan. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.26 <Page> The following accounts are NOT eligible to be included in determining the sales charge on your purchase: - - Accounts of pension and retirement plans with multiple participants, such as 401(k) plans (which are combined to reduce the sales charge for the entire pension or retirement plan and therefore are not used to reduce the sales charge for your individual accounts); - - Investments in Class A shares where the sales charge is waived, for example, purchases through wrap accounts, including Ameriprise Strategic Portfolio Service ADVANTAGE (SPS); - - Investments in Class D, Class E, or Class Y shares; - - Investments in 529 plans, donor advised funds, variable annuities, variable life insurance products, wrap accounts or managed separate accounts; and - - Charitable and irrevocable trust accounts. If you purchase RiverSource fund shares through different channels or different financial intermediaries, and you want to include those assets toward a reduced sales charge, you must inform Ameriprise Financial Services, your financial advisor or investment professional in writing about the other accounts when placing your purchase order. When placing your purchase order, you must provide your most recent account statement and contact information regarding the other accounts. A financial intermediary other than Ameriprise Financial Services may require additional information. UNLESS YOU PROVIDE AMERIPRISE FINANCIAL SERVICES, YOUR FINANCIAL ADVISOR OR YOUR INVESTMENT PROFESSIONAL IN WRITING WITH INFORMATION ABOUT ALL OF THE ACCOUNTS THAT MAY COUNT TOWARD A SALES CHARGE REDUCTION, THERE CAN BE NO ASSURANCE THAT YOU WILL RECEIVE ALL OF THE REDUCTIONS FOR WHICH YOU MAY BE ELIGIBLE. For more information on rights of accumulation, please see the SAI. LETTER OF INTENT (LOI) Generally, if you intend to invest $50,000 or more over a period of 13 months, you may be able to reduce the front-end sales charges for investments in Class A shares by completing and filing a LOI form. The LOI becomes effective only after the form is processed in good order by the distributor. An LOI can be backdated up to a maximum of 90 days. If the LOI is backdated, you may include prior investments in Class A shares that were charged a front-end sales load toward the LOI commitment amount. If the LOI is backdated, the 13 month period begins on the date of the earliest purchase included in the LOI. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.27 <Page> HOLDINGS MORE THAN 90 DAYS OLD. Purchases made more than 90 days before your LOI is processed by the distributor will not be counted towards the commitment amount of the LOI and cannot be used as the starting point for the LOI. While these purchases cannot be included in an LOI, they may help you obtain a reduced sales charge on future purchases as described in "Rights of Accumulation." NOTIFICATION OBLIGATION. If purchasing shares in a brokerage account or through a financial intermediary, you must request the reduced sales charge when you buy shares. If you do not complete and file the LOI form, or do not request the reduced sales charge at the time of purchase, you will not be eligible for the reduced sales charge. For more details on LOIs, please contact your financial advisor, investment professional or see the SAI. WAIVERS OF THE SALES CHARGE FOR CLASS A SHARES Sales charges do not apply to: - - current or retired Board members, officers or employees of the Fund or Ameriprise Financial or its subsidiaries, their spouses or domestic partners, children and parents. - - current or retired Ameriprise Financial Services financial advisors, employees of financial advisors, their spouses or domestic partners, children and parents. - - portfolio managers employed by subadvisers of the RiverSource funds, including their spouses or domestic partners, children and parents. - - registered representatives and other employees of financial intermediaries having a sub-distribution agreement with the distributor, including their spouses, domestic partners, children and parents. - - qualified employee benefit plans offering participants daily access to RiverSource funds. Eligibility must be determined in advance. For assistance, please contact your financial advisor or investment professional. Participants in certain qualified plans where the initial sales charge is waived may be subject to a deferred sales charge of up to 4%. - - shareholders who have at least $1 million in RiverSource funds. If the investment is sold within one year after purchase, a CDSC of 1% may be charged. - - direct rollovers from Ameriprise Retirement Services, provided that the rollover involves a transfer of Class Y shares in this Fund to Class A shares in this Fund. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.28 <Page> - - purchases made: - with dividend or capital gain distributions from this Fund or from the same class of another RiverSource fund, - through or under a wrap fee product or other investment product sponsored by the distributor or another authorized broker-dealer, investment advisor, bank or investment professional, - within a segregated separate account offered by Nationwide Life Insurance Company or Nationwide Life and Annuity Insurance Company, - through American Express Personal Trust Services' Asset-Based pricing alternative, provided by American Express Bank, FSB. - - shareholders whose original purchase was in a Strategist fund merged into a RiverSource fund in 2000. Policies related to reducing or waiving the sales charge may be modified or withdrawn at any time. UNLESS YOU PROVIDE AMERIPRISE FINANCIAL SERVICES, YOUR FINANCIAL ADVISOR OR INVESTMENT PROFESSIONAL WITH INFORMATION IN WRITING ABOUT ALL OF THE FACTORS THAT MAY COUNT TOWARD A WAIVER OF THE SALES CHARGE, THERE CAN BE NO ASSURANCE THAT YOU WILL RECEIVE ALL OF THE WAIVERS FOR WHICH YOU MAY BE ELIGIBLE. You also may view this information about sales charges and breakpoints free of charge on the Fund's website. Go to www.riversource.com/investments and click on the hyperlink "Sales Charge Discount Information." CLASS B AND CLASS C -- CONTINGENT DEFERRED SALES CHARGE (CDSC) ALTERNATIVE FOR CLASS B, the CDSC is based on the sale amount and the number of years -- including the year of purchase -- between purchase and sale. The following table shows how CDSC percentages on sales decline: <Table> <Caption> IF THE SALE IS MADE DURING THE: THE CDSC PERCENTAGE RATE IS:* First year 5% Second year 4% Third year 4% Fourth year 3% Fifth year 2% Sixth year 1% Seventh year 0% </Table> * Because of rounding in the calculation, the portion of the CDSC retained by the distributor may vary and the actual CDSC you pay may be more or less than the CDSC calculated using these percentages. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.29 <Page> Although there is no front-end sales charge when you buy Class B shares, the distributor pays a sales commission of 4% to financial intermediaries that sell Class B shares. A portion of this commission may, in turn, be paid to your financial advisor. The distributor receives any CDSC imposed when you sell your Class B shares. Purchases made prior to May 21, 2005 age on a calendar year basis. Purchases made beginning May 21, 2005 age on a daily basis. For example, a purchase made on Nov. 12, 2004 will complete its first year on Dec. 31, 2004 under calendar year aging. However, a purchase made on Nov. 12, 2005 will complete its first year on Nov. 11, 2006 under daily aging. For Class B shares purchased prior to May 21, 2005, those shares will convert to Class A shares in the ninth calendar year of ownership. For Class B shares purchased beginning May 21, 2005, those shares will convert to Class A shares one month after the completion of the eighth year of ownership. FOR CLASS C, a 1% CDSC may be charged if you sell your shares within one year after purchase. Although there is no front-end sales charge when you buy Class C shares, the distributor pays a sales commission of 1% to financial intermediaries that sell Class C shares. A portion of this commission may, in turn, be paid to your financial advisor. The distributor receives any CDSC imposed when you sell your Class C shares. For both Class B and Class C, if the amount you sell causes the value of your investment to fall below the cost of the shares you have purchased, the CDSC will be based on the lower of the cost of those shares purchased or market value. Because the CDSC is imposed only on sales that reduce your total purchase payments, you do not have to pay a CDSC on any amount that represents appreciation in the value of your shares, income earned by your shares, or capital gains. In addition, the CDSC on your sale, if any, will be based on your oldest purchase payment. The CDSC on the next amount sold will be based on the next oldest purchase payment. EXAMPLE Assume you had invested $10,000 in Class B shares and that your investment had appreciated in value to $12,000 after 3 1/2 years, including reinvested dividends and capital gain distributions. You could sell up to $2,000 worth of shares without paying a CDSC ($12,000 current value less $10,000 purchase amount). If you sold $2,500 worth of shares, the CDSC would apply to the $500 representing part of your original purchase price. The CDSC rate would be 3% because the sale was made during the fourth year after the purchase. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.30 <Page> WAIVERS OF THE CDSC FOR CLASS B SHARES The CDSC will be waived on sales of shares: - - in the event of the shareholder's death, - - held in trust for an employee benefit plan, or - - held in IRAs or certain qualified plans if Ameriprise Trust Company is the custodian, such as Keogh plans, tax-sheltered custodial accounts or corporate pension plans, provided that the shareholder is: - at least 59 1/2 years old AND - taking a retirement distribution (if the sale is part of a transfer to an IRA or qualified plan, or a custodian-to-custodian transfer, the CDSC will not be waived) OR - selling under an approved substantially equal periodic payment arrangement. WAIVERS OF THE CDSC FOR CLASS C SHARES The CDSC will be waived on sales of shares in the event of the shareholder's death. EXCHANGING/SELLING SHARES TO SELL OR EXCHANGE SHARES HELD WITH FINANCIAL INTERMEDIARIES OTHER THAN AMERIPRISE FINANCIAL SERVICES, PLEASE CONSULT YOUR FINANCIAL INTERMEDIARY. SEE "TRANSACTIONS THROUGH UNAFFILIATED FINANCIAL INTERMEDIARIES" FOR MORE INFORMATION. THE FOLLOWING SECTION EXPLAINS POLICIES OF THE RIVERSOURCE FUNDS ON HOW YOU CAN EXCHANGE OR SELL SHARES HELD WITH AMERIPRISE FINANCIAL SERVICES. EXCHANGES You may exchange your Fund shares at no charge for shares of the same class of any other publicly offered RiverSource fund. Exchanges into RiverSource Tax-Exempt Money Market Fund may only be made from Class A shares. For complete information on the other fund, including fees and expenses, read that fund's prospectus carefully. Your exchange will be priced at the next NAV calculated after your transaction request is received in good order. MARKET TIMING IS FREQUENT OR SHORT-TERM TRADING BY CERTAIN SHAREHOLDERS INTENDED TO PROFIT AT THE EXPENSE OF OTHER SHAREHOLDERS BY SELLING SHARES OF A FUND SHORTLY AFTER PURCHASE. MARKET TIMING MAY ADVERSELY IMPACT A FUND'S PERFORMANCE BY PREVENTING THE INVESTMENT MANAGER FROM FULLY INVESTING THE ASSETS OF THE FUND, DILUTING THE VALUE OF SHARES HELD BY LONG-TERM SHAREHOLDERS, OR INCREASING THE FUND'S TRANSACTION COSTS. SEE "VALUING FUND SHARES" FOR A DISCUSSION OF THE FUND'S POLICY ON FAIR VALUE PRICING, WHICH IS INTENDED, IN PART, TO REDUCE THE FREQUENCY AND EFFECT OF MARKET TIMING. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.31 <Page> THE FUND'S BOARD HAS ADOPTED A POLICY THAT IS DESIGNED TO DETECT AND DETER MARKET TIMING. THE FUND SEEKS TO ENFORCE THIS POLICY AS FOLLOWS: - - The Fund tries to distinguish market timing from trading that it believes is not harmful, such as periodic rebalancing for purposes of asset allocation or dollar cost averaging. Under the Fund's procedures, there is no set number of transactions in the Fund that constitutes market timing. Even one purchase and subsequent sale by related accounts may be market timing. Generally, the Fund seeks to restrict the exchange privilege of an investor who makes more than three exchanges into or out of the Fund in any 90-day period. Accounts held by a retirement plan or an institution for the benefit of its participants or clients, which typically engage in daily transactions, are not subject to this limit. The Fund seeks the assistance of financial intermediaries in applying similar restrictions on the sub-accounts of their participants or clients. - - If an investor's trading activity is determined to be market timing or otherwise harmful to existing shareholders, the Fund reserves the right to modify or discontinue the investor's exchange privilege or reject the investor's purchases or exchanges, including purchases or exchanges accepted by a financial intermediary. The Fund may treat accounts it believes to be under common control as a single account for these purposes, although it may not be able to identify all such accounts. - - Although the Fund does not knowingly permit market timing, it cannot guarantee that it will be able to identify and restrict all short-term trading activity. The Fund receives purchase and sale orders through financial intermediaries where market timing activity may not always be successfully detected. Other exchange policies: - - Exchanges must be made into the same class of shares of the new fund. - - If your exchange creates a new account, it must satisfy the minimum investment amount for new purchases. - - Once we receive your exchange request, you cannot cancel it. - - Shares of the new fund may not be used on the same day for another exchange. - - If your shares are pledged as collateral, the exchange will be delayed until written approval is received from the secured party. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.32 <Page> SELLING SHARES You may sell your shares at any time. The payment will be mailed within seven days after your request is received in good order. When you sell shares, the amount you receive may be more or less than the amount you invested. Your sale price will be the next NAV calculated after your request is received in good order, minus any applicable CDSC. REPURCHASES. You can change your mind after requesting a sale and use all or part of the proceeds to purchase new shares in the same account from which you sold. If you reinvest in Class A, you will purchase the new shares at NAV rather than the offering price on the date of a new purchase. If you reinvest in Class B or Class C, any CDSC you paid on the amount you are reinvesting also will be reinvested. To take advantage of this waiver, you must send a written request within 90 days of the date your sale request was processed and include your account number. This privilege may be limited or withdrawn at any time and use of this option may have tax consequences. The Fund reserves the right to redeem in kind. For more details and a description of other sales policies, please see the SAI. If you decide to sell your shares within 30 days of a telephoned-in address change, a written request is required. IMPORTANT: Payments sent by a bank authorization, check or money order that are not guaranteed may take up to ten days to clear. This may cause your scheduled arrangement or unscheduled request to fail to process if the requested amount includes unguaranteed funds.

The Fund may modify or discontinue electronic privileges at any time for any shareholder without prior notice as deemed necessary and in the best interest of the Fund. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.35 <Page> DISTRIBUTIONS AND TAXES As a shareholder you are entitled to your share of the Fund's net income and net gains. The Fund distributes dividends and capital gains to qualify as a regulated investment company and to avoid paying corporate income and excise taxes. DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS The Fund's net investment income is distributed to you as DIVIDENDS. Dividends may be composed of qualifying dividend income, which is eligible for preferential tax rates under current tax law, as well as other ordinary dividend income, which may include non-qualifying dividends, interest income and short-term capital gains. Capital gains are realized when a security is sold for a higher price than was paid for it. Each realized capital gain or loss is long-term or short-term depending on the length of time the Fund held the security. Realized capital gains and losses offset each other. The Fund offsets any net realized capital gains by any available capital loss carryovers. Net short-term capital gains are included in net investment income. Net realized long-term capital gains, if any, are distributed by the end of the calendar year as CAPITAL GAIN DISTRIBUTIONS. REINVESTMENTS Dividends and capital gain distributions are automatically reinvested in additional shares in the same class of the Fund, unless: - - you request distributions in cash, or - - you direct the Fund to invest your distributions in the same class of any publicly offered RiverSource fund for which you have previously opened an account. We reinvest the distributions for you at the next calculated NAV after the distribution is paid. If you choose cash distributions, you will receive cash only for distributions declared after your request has been processed. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT D.36 <Page> TAXES Distributions are subject to federal income tax and may be subject to state and local taxes in the year they are declared. You must report distributions on your tax returns, even if they are reinvested in additional shares. If you buy shares shortly before the record date of a distribution, you may pay taxes on money earned by the Fund before you were a shareholder. You will pay the full pre-distribution price for the shares, then receive a portion of your investment back as a distribution, which may be taxable. For tax purposes, an exchange is considered a sale and purchase, and may result in a gain or loss. A sale is a taxable transaction. If you sell shares for less than their cost, the difference is a capital loss. If you sell shares for more than their cost, the difference is a capital gain. Your gain may be short term (for shares held for one year or less) or long term (for shares held for more than one year). You may not create a tax loss, based on paying a sales charge, by exchanging shares within 91 days of purchase. If you buy Class A shares and within 91 days exchange into another fund, you may not include the sales charge in your calculation of tax gain or loss on the sale of the first fund you purchased. The sales charge may be included in the calculation of your tax gain or loss on a subsequent sale of the second fund you purchased. For more information, see the SAI. Selling shares held in an IRA or qualified retirement account may subject you to federal taxes, penalties and reporting requirements. Please consult your tax advisor. IMPORTANT: This information is a brief and selective summary of some of the tax rules that apply to this Fund. Because tax matters are highly individual and complex, you should consult a qualified tax advisor.

Any decisions of the member to grant pre-approvals shall be presented to the Committee at its next regularly scheduled meeting. ROLE AND RESPONSIBILITIES The function of the Committee is oversight; it is American Express Financial Corporation's responsibility to maintain appropriate systems for accounting and internal control over financial reporting, and the Auditor's responsibility to plan and carry out a proper audit. Specifically, American Express Financial Corporation is responsible for: (1) the preparation, presentation and integrity of the Fund's financial statements; (2) the maintenance of appropriate accounting and financial reporting principles and policies; and (3) the maintenance of internal control over financial reporting and other procedures designed to assure compliance with accounting standards and related laws and regulations. The Auditor is responsible for planning and carrying out an audit consistent with applicable legal and professional standards and the terms of their engagement letter. Nothing in the Charter shall be construed to reduce the responsibilities or liabilities of the Fund's service providers, including the Auditor. Although the Committee is expected to take a detached and questioning approach to the matters that come before it, the review of a Fund's financial statements by the Committee is not an audit, nor does the Committee's review substitute for the responsibilities of American Express Financial Corporation's for preparing, or the Auditor for auditing, the financial statements. Members of the Committee are not employees of the Fund and, in serving on this Committee, are not, and do not hold themselves out to be, acting as accountants or auditors. As such, it is not the duty or responsibility of the Committee or its members to conduct "field work" or other types of auditing or accounting reviews or procedures. RIVERSOURCE NEW DIMENSIONS FUND -- PROXY STATEMENT F.5 <Page> In discharging their duties, the members of the Committee are entitled to rely on information, opinions, reports, or statements, including financial statements and other financial data, if prepared or presented by: (1) one or more officers of the Fund whom the director reasonably believes to be reliable and competent in the matters presented; (2) legal counsel, public accountants, or other persons as to matters the director reasonably believes are within the person's professional or expert competence; or (3) a Board committee of which the director is not a member. OPERATIONS The Board shall adopt and approve this Charter and may amend it on the Board's own motion. The Committee shall review this Charter at least annually and recommend to the full Board any changes the Committee deems appropriate. The Committee may select one of its members to be the chair and may select a vice chair. A majority of the members of the Committee shall constitute a quorum for the transaction of business at any meeting of the Committee. The action of a majority of the members of the Audit Committee present at a meeting at which a quorum is present shall be the action of the Committee. The Committee shall meet on a regular basis and at least four times annually and is empowered to hold special meetings as circumstances require. The Chairperson or a majority of the members shall be authorized to call a meeting of the Committee or meetings may be fixed in advance by the Committee. The agenda shall be prepared under the direction and control of the Chairperson. The Committee shall ordinarily meet in person; however, members may attend telephonically, and the Committee may act by written consent, to the extent permitted by law and by the Fund's bylaws. The Committee shall have the authority to meet privately and to admit non-members individually. The Committee may also request to meet with internal legal counsel and compliance personnel of American Express Financial Corporation and with entities that provide significant accounting or administrative services to the Fund to discuss matters relating to the Fund's accounting and compliance as well as other Fund-related matters. The Committee shall prepare and retain minutes of its meetings and appropriate documentation of decisions made outside of meetings by delegated authority. The Committee shall evaluate its performance at least annually.

WE ENCOURAGE YOU TO READ THE FULL TEXT OF THE ENCLOSED PROXY STATEMENT. Q: WHAT CHANGES HAVE RECENTLY TAKEN PLACE? On Sept. 30, the fund's investment manager, Ameriprise Financial, Inc. ("Ameriprise Financial") (formerly American Express Financial Corporation) was spun off from its parent company, American Express Company. The investment management functions were then moved to RiverSource Investments, LLC ("RiverSource Investments"), a wholly-owned subsidiary of Ameriprise Financial. The Board of Directors ("Board") changed the name of each fund and the funds are now listed in newspapers under RiverSource. Q: WHY AM I BEING ASKED TO VOTE? Mutual funds are required to get shareholders' approval for certain contracts and certain kinds of changes, like the ones included in this proxy statement. Q: IS MY VOTE IMPORTANT? Absolutely! While the Board of each RiverSource Fund has reviewed these changes and recommends you approve them, you have the right to voice your opinion. Until the fund is sure that a quorum has been reached (50% of existing shares), it will continue to contact shareholders asking them to vote. These efforts cost money -- so please, vote immediately. Q: WHAT AM I BEING ASKED TO VOTE ON? Shareholders are being asked to vote on: - - The merger ("Reorganization") of RiverSource New Dimensions Fund and RiverSource Large Cap Equity Fund. - - Election of Board members. - - An amendment to the Fund's Articles of Incorporation to permit the Board to establish the minimum account value and to change the name of the corporation to "RiverSource" consistent with the name of the fund. - - An Investment Management Services Agreement ("IMS Agreement") with RiverSource Investments. <Page> We encourage you to read the full text of the proxy statement to obtain a more detailed understanding of the issues. Q: IF APPROVED, WHEN WILL THE REORGANIZATION HAPPEN? If shareholders approve the Reorganization, it will take place shortly after the shareholder meeting. In the interim, however, it will be important for the Fund to have a properly elected Board and an IMS agreement that has been approved by shareholders. Q: WHAT DO BOARD MEMBERS DO? Board members represent the interests of the shareholders and oversee the management of the fund. Q: WHAT CHANGES ARE PROPOSED TO THE INVESTMENT MANAGEMENT SERVICES AGREEMENT? In September, the Fund's investment manager, Ameriprise Financial was spun off from its parent company, American Express Company. The investment management functions were then moved to RiverSource Investments, a wholly-owned subsidiary of Ameriprise Financial. While this transfer did not cause a termination of the IMS Agreement, or otherwise affect its terms and conditions, the Board determined that it would be prudent to give shareholders an opportunity to vote on the IMS Agreement. The IMSAgreement also clarifies the circumstances under which the Board may change an index for purposes of calculating a performance incentive adjustment. Q: HOW DOES THE BOARD RECOMMEND THAT I VOTE? After careful consideration, the Board recommends that you vote FOR each proposal. Q: HOW DO I VOTE? You can vote in one of four ways: - - By mail with the enclosed proxy card - - By telephone - - By web site - - In person at the meeting Please refer to the enclosed voting instruction card for the telephone number and internet address. Q: WHOM SHOULD I CALL IF I HAVE QUESTIONS?

APPROVE OR REJECT THE AGREEMENT AND PLAN OF REORGANIZATION SUMMARY This proxy statement/prospectus is being used by the Selling Fund to solicit proxies to vote at a meeting of shareholders. Shareholders will consider a proposal to approve the Agreement providing for the Reorganization of the Selling Fund into the Buying Fund. A form of the Agreement is included in Exhibit A. The following is a summary. More complete information appears later in this proxy statement/prospectus. You should read the entire proxy statement/prospectus and the exhibits because they contain details that are not in the summary. HOW THE REORGANIZATION WILL WORK - - The Selling Fund will transfer all of its assets to the Buying Fund. The Buying Fund will assume the Selling Fund's stated liabilities. - - The Buying Fund will issue shares of Classes A, B, C, I and Y to the Selling Fund in an amount equal to the value of the assets of Classes A, B, C, I and Y that it receives from the Selling Fund, less the liabilities it assumes. These shares will be distributed to the Selling Fund's shareholders in proportion to their holdings in the Selling Fund. If you already have a Buying Fund account, shares distributed in the Reorganization will be added to that account. As a result, when average cost is calculated for income tax purposes, the cost of the shares in the two accounts you owned will be combined. - - As part of the Reorganization, systematic transactions (such as bank authorizations and systematic payouts) currently set up for your Selling Fund account will be transferred to your new Buying Fund account. If you do not want your systematic transactions to continue, please contact your financial advisor to make changes. - - Neither the Selling Fund nor the shareholders of the Selling Fund will pay any sales charge in connection with the Reorganization. - - After the Reorganization is completed, current Selling Fund shareholders will be shareholders of the Buying Fund. The Selling Fund will be terminated. COMPARISON OF THE SELLING FUND AND THE BUYING FUND Both the Selling Fund and the Buying Fund: - - Are structured as a series of capital stock of an open-end management investment company organized as a Minnesota corporation. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 7 <Page> - - Have RiverSource Investments, LLC (the "investment manager" or "RiverSource Investments") as an investment adviser. - - Have the same policies for buying and selling shares and the same exchange rights. - - Have the same distribution policies, although the Selling Fund pays dividends quarterly and the Buying Fund pays dividends annually. - - Have different classes of shares: Classes A, B, C, I and Y. COMPARISON OF INVESTMENT OBJECTIVES The investment objectives for the Funds are as follows: SELLING FUND: The Fund seeks to provide shareholders with current income and growth of capital. BUYING FUND: The Fund seeks to provide shareholders with long-term capital growth. COMPARISON OF INVESTMENT STRATEGIES Although both Funds have adopted policies to invest at least 80% of net assets in common stocks, the Selling Fund may also count securities convertible into common stocks toward this 80% test. As part of its income objective, the Selling Fund may invest in income-producing equity securities and short-term debt instruments. Additionally, while the Buying Fund is run 100% as a quantitative fund, where portfolio managers select stocks based on sophisticated statistical analysis, the Selling Fund is run 50% using these same quantitative methodologies and 50% using more traditional stock picking methodologies. Prior to October 2005, a larger percentage of the Selling Fund was run using these more traditional stock picking methodologies. Detailed strategies for the Selling Fund and the Buying Fund are set forth below: STOCK (SELLING FUND): The Fund's assets primarily are invested in common stocks and securities convertible into common stocks. Under normal market conditions, at least 80% of the Fund's net assets are invested in these securities. In pursuit of its income objective, the Fund will invest in income-producing equity securities (such as convertible securities and preferred stocks) and short-term debt instruments (such as commercial paper). The Fund will provide shareholders with at least 60 days' notice of any change in the 80% policy. In pursuit of the Fund's objective, the investment manager uses two different approaches to the selection of equity investments. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 8 <Page> With respect to approximately 50% of the Fund's portfolio, the investment manager uses a traditional stock selection methodology and chooses investments by: - - Considering opportunities and risks by reviewing overall market conditions and industry outlook. - - Identifying market trends that the investment manager believes will lead to good long-term growth potential. - - Identifying companies with strong, sustainable earnings growth based on: - effective management, as demonstrated by overall performance, - competitive market position, and - financial strength. - - Focusing on those companies that the investment manager considers to be blue chips. Blue chip stocks are issued by companies with a market capitalization of at least $1 billion, an established management, a history of consistent earnings and a leading position within their respective industries. - - Identifying investments that contribute to portfolio diversification. - - Identifying income-producing securities. In evaluating whether to sell a security, the investment manager considers, among other factors, whether: - - The security is overvalued relative to other potential investments. - - The security has reached the investment manager's price objective. - - The company has met the investment manager's earnings and/or growth expectations. - - Political, economic or other events could affect the company's performance. With respect to approximately 50% of the Fund's portfolio, the investment manager uses proprietary quantitative methods based on sophisticated statistical analysis and chooses investments by: The universe of stocks from which the investment manager selects the Fund's investments will be those included in the Fund's benchmark, the Standard & Poor's 500 Index (S&P 500 Index). Through extensive analysis of the domestic equity markets, the investment manager has identified characteristics of certain stocks that have historically outperformed their benchmarks. The Fund will hold both growth and value stocks. Characteristics used to select stocks for the Fund include: - - Superior growth characteristics such as: - strong earnings growth, - positive earnings that exceed expectations published by third-party business analysts, RIVERSOURCE STOCK FUND -- PROXY STATEMENT 9 <Page> - consistency of earnings, and - strong positive price trend. - - Superior value characteristics based on analysis of current stock prices relative to estimates of future prices. In selecting the stocks from the S&P 500 Index for the Fund's portfolio, the investment manager employs a rigorous process for evaluating the relationship between the risk associated with each security and its potential for positive returns. This process includes factors such as: - - Limits on positions relative to the benchmark through overweighting or underweighting. - - Limits on sector and industry allocations relative to the benchmark. - - Limits on size of holdings relative to market liquidity. DISCIPLINED EQUITY (BUYING FUND): Under normal market conditions, at least 80% of the Fund's net assets are invested in equity securities of companies listed on U.S. exchanges with market capitalizations greater than $5 billion at the time of purchase. The Fund will provide shareholders with at least 60 days' notice of any change in the 80% policy. In pursuit of the Fund's objective, the investment manager will choose equity investments by employing proprietary quantitative methods based on sophisticated statistical analysis. The universe of stocks from which the investment manager selects the Fund's investments primarily will be those included in the Fund's benchmark, the S&P 500. Through extensive analysis of the domestic equity markets, the investment manager has identified characteristics of certain stocks that have historically outperformed their benchmarks. The Fund will hold both growth and value stocks. Characteristics used to select stocks for the Fund include: - - Superior growth characteristics such as: - strong earnings growth, - positive earnings that exceed expectations published by third-party business analysts, - consistency of earnings, and - strong positive price trend. - - Superior value characteristics based on analysis of current stock prices relative to estimates of future prices. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 10 <Page> In selecting the stocks for the Fund's portfolio, the investment manager employs a rigorous process for evaluating the relationship between the risk associated with each security and its potential for positive returns. This process includes factors such as: - - Limits on positions relative to the benchmark through overweighting or underweighting. - - Limits on sector and industry allocations relative to the benchmark. - - Limits on size of holdings relative to market liquidity. BOTH FUNDS: - - UNUSUAL MARKET CONDITIONS. During unusual market conditions, each of the Funds may temporarily invest more of its assets in money market securities than during normal market conditions. Although investing in these securities would serve primarily to avoid losses, this type of investing also could prevent the Fund from achieving its investment objective. During these times, the portfolio managers may make frequent securities trades that could result in increased fees, expenses and taxes, and decreased performance. - - OTHER INVESTMENT STRATEGIES. Each Fund may invest in other securities and may use other investment strategies that are not principal investment strategies. Additionally, each Fund may use derivatives (financial instruments where the value depends upon, or is derived from, the value of something else) such as futures, options and forward contracts, to produce incremental earnings, to hedge existing positions or to increase flexibility. Just as with securities in which the Fund invests directly, derivatives are subject to a number of risks, including market, liquidity, interest rate and credit risk. In addition, a relatively small price movement in the underlying security, currency or index may result in a substantial gain or loss for the Fund using derivatives. Even though the Fund's policies permit the use of derivatives in this manner, the portfolio managers are not required to use derivatives. COMPARISON OF FUNDAMENTAL POLICIES The Buying Fund shareholders will vote on changes to the fundamental policies for the Buying Fund at a meeting scheduled to be held on the same day as the Selling Fund shareholder meeting. The proposed changes are shown in Exhibit B. If all of the proposed changes to the Buying Fund's fundamental policies are approved, the differences in investment policies will be as follows: Both Funds have substantially similar fundamental investment policies. The Buying Fund has a policy permitting borrowing money for temporary purposes in an amount not exceeding one-third of the market value of its total assets. The Selling Fund has a similar policy that applies to money or property and permits borrowing only for extraordinary or emergency purposes. The Buying Fund has a policy prohibiting the issuing of senior securities, except as RIVERSOURCE STOCK FUND -- PROXY STATEMENT 11 <Page> permitted under the 1940 Act. Even though this is not stated as a fundamental policy of the Selling Fund, the Fund is nonetheless subject to that restriction under the provisions of the 1940 Act. The Buying Fund has a policy that it will not purchase more than 10% of the outstanding voting securities of an issuer, except up to 25% of its total assets may be invested without regard to this 10% limitation. The Selling Fund has a similar policy, but does not have the 25% exception. The Buying Fund has a policy that it will not invest more than 5% of its total assets in securities of any one company, government or political subdivision thereof, except the limitation will not apply to investments in securities issued by the U.S. government, its agencies, or instrumentalities or other investment companies, and except that up to 25% of its total assets may be invested without regard to this 5% limitation. The Selling Fund has a similar policy, but does not include other investment companies in the exception. The Buying Fund has a policy permitting the Fund to lend fund securities and participate in an interfund lending program up to 33 1/3% of the value of the fund's total assets. This policy does not prohibit the Buying Fund from purchasing money market securities, loans, loan participation or other debt securities, or from entering into repurchase agreements. The Selling Fund has a policy permitting the Selling Fund to lend fund securities up to 30% of its net assets. In addition, the Selling Fund has a policy that it may make cash loans up to 5% of its total assets. The Buying Fund has a policy prohibiting loans of any part of its assets to the investment manager, its board members and officers and to the board members and officers of the Buying Fund. Even though this is not stated as the fundamental policy of the Selling Fund, the Fund is nonetheless subject to that restriction under the provisions of the 1940 Act. If shareholders of the Selling Fund approve the Reorganization, they will be subject to the fundamental investment policies of the Buying Fund. The investment manager does not believe that the differences between the fundamental investment policies will result in any material difference in the way the Funds are managed. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 12 <Page> RISK FACTORS The principal risks of investing in each of the Selling Fund and the Buying Fund are similar. However, because more of its net assets are dedicated to quantitative methodologies, the Buying Fund may have increased exposure to the potential risks of such quantitative methodologies. These risks are highlighted under Market Risk. The principal risks associated with an investment in each of the Buying Fund and the Selling Fund are shown below: <Table> <Caption> RISK STOCK DISCIPLINED EQUITY Active Management Risk x x Issuer Risk x x Market Risk x x </Table> - - ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance therefore will reflect in part the ability of the portfolio managers to make investment decisions that are suited to achieving the Fund's investment objective. Due to its active management, the Fund could underperform other mutual funds with similar investment objectives. - - ISSUER RISK. An issuer may perform poorly and therefore, the value of its stocks and bonds may decline. Poor performance may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, or other factors. - - MARKET RISK. The market value of securities may fall or fail to rise. Market risk may affect a single issuer, sector of the economy, industry, or the market as a whole. The market value of securities may fluctuate, sometimes rapidly and unpredictably. This risk is generally greater for small and mid-sized companies, which tend to be more vulnerable to adverse developments. In addition, focus on a particular style, for example, investment in growth or value securities, may cause the Fund to underperform other mutual funds if that style falls out of favor with the market. The quantitative methodology employed by the investment manager has been extensively tested using historical securities market data, but has only recently begun to be used to manage open-end mutual funds. There can be no assurance that the methodology will enable the Fund to achieve its objective.

TAX CONSEQUENCES The Reorganization is expected to be tax-free for federal income tax purposes and will not take place unless the Selling Fund and the Buying Fund receive a satisfactory opinion of tax counsel, substantially to that effect. Accordingly, no gain or loss is expected to be recognized by the Selling Fund or its shareholders as a direct result of the Reorganization. Prior to or after completion of the Reorganization, no major sell-offs to realign the portfolio are expected in relation to, or as a result of the Reorganization. However, the Reorganization will end the tax year of the Selling Fund, and so it will accelerate distributions from the Selling Fund for its short tax year ending on the date of the Reorganization to shareholders. Those tax year-end distributions, which are taxable, will also include any capital gains resulting from portfolio turnover prior to the implementation of the Reorganization. At any time prior to the consummation of the Reorganization a shareholder may redeem shares. This would likely result in recognition of gain or loss to the shareholder for federal income tax purposes. The tax basis and holding period of the shareholders' Selling Fund shares are expected to carry over to the shareholders' new shares in the Buying Fund. For more information about the federal income tax consequences of the Reorganization, see the section entitled "Tax Status of the Reorganization." RIVERSOURCE STOCK FUND -- PROXY STATEMENT 14 <Page> FEES AND EXPENSES The following table describes the fees and expenses, adjusted to reflect current fees, that you pay if you buy and hold shares of the Selling Fund or shares of the Buying Fund. The table also shows pro forma expenses of the Buying Fund assuming the proposed Reorganization had been effective during the most recent fiscal year, adjusted to reflect current fees. If shareholders approve the Reorganization, for a period of 12 months following implementation of the Reorganization, the investment manager and its affiliates have agreed to waive fees or to cap expenses of the Buying Fund sufficient to keep total expenses within 5 basis points (0.05%) of the Selling Fund's expense ratio at the time of the Reorganization. For a period of 5 years following the 12-month period, the investment manager and its affiliates have agreed to waive fees or to cap expenses of the Buying Fund at the median expense ratio of the Buying Fund's Lipper peer group. The level of the Buying Fund's expense cap will be reviewed and reset annually by the Buying Fund's Board. For purposes of these calculations, the expense ratio will be determined prior to application of the performance incentive adjustment. The fees and expenses below exclude the costs of this Reorganization as these will be paid by Ameriprise Financial.

(c) Stock is a feeder fund that is part of a master/feeder structure. For Stock, both in this table and the following example fund operating expenses include expenses charged by both the Fund and its master portfolio. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 16 <Page> NOTES TO ANNUAL FUND OPERATING EXPENSES (CONTINUED). (d) The management fee rate is the actual fee rate charged as of fiscal year ended Sept. 30, 2005. It includes the impact of a performance incentive adjustment fee that decreased the management fee by 0.02% for the fiscal year ended Sept. 30, 2005 for Stock. The index against which Stock's performance is measured for purposes of determining the performance incentive adjustment is the Lipper Large-Cap Core Funds Index. (e) Other expenses include an administrative services fee, a transfer agency fee, a custody fee and other nonadvisory expenses and, for Class Y shares, a shareholder service fee. The other expense ratios shown in this chart have been adjusted to reflect the new administrative fee that went into effect in Oct. 2005. (f) The management fee ratio shown reflects what the ratio would be based on the Fund's average net assets as of July 31, 2005 under the proposed management fee schedule. The ratio includes the impact of a performance incentive adjustment fee that increased the management fee by .02% for the most recent fiscal year for Disciplined Equity. The index against which Disciplined Equity's performance is measured for purposes of determining the performance incentive adjustment is the Lipper Large-Cap Core Funds Index. (g) For Disciplined Equity, the investment manager and its affiliates have contractually agreed to waive certain fees and to absorb certain expenses until July 31, 2006, 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 expenses, before giving effect to any performance incentive adjustment (.02% increase for the most recent fiscal year), will not exceed 1.25% for Class A, 2.04% for Class B, 2.06% for Class C, 0.93% for Class I and 1.06% for Class Y. (h) If shareholders approve the Reorganization, the investment manager and its affiliates have contractually agreed to waive certain fees and to absorb certain expenses for six years following implementation of the Reorganization, unless sooner terminated at the discretion of the Fund's Board. Any amounts waived will not be reimbursed by the Fund. Under this agreement, in year one, net expenses, before giving effect to any performance incentive adjustment (.02% increase for the most recent fiscal year), will not exceed 1.00% for Class A, 1.78% for Class B, 1.77% for Class C, 0.64% for Class I and 0.84% for Class Y. In years two through six after the merger, expense caps of the Buying Fund will be at the median expense ratio of the Buying Fund Lipper peer group reviewed and reset annually by the Board. (i) Other expenses include an administrative services fee, a transfer agency fee, a custody fee and other nonadvisory expenses and, for Class Y shares, a shareholder service fee. The other expense ratios shown have been adjusted to reflect the new administrative fee that went into effect in October 2005. In addition, these ratios have been adjusted to reflect closed account fees for accounts that will be closed following the Reorganization.

RIVERSOURCE STOCK FUND -- PROXY STATEMENT 19 <Page> THE REORGANIZATION TERMS OF THE REORGANIZATION The Board has approved the Agreement, a copy of which is attached as Exhibit A. The Agreement provides for Reorganization on the following terms: - - The Reorganization is scheduled to occur on the first day that the New York Stock Exchange is open for business following shareholder approval and receipt of any necessary regulatory approvals, but may occur on any later date agreed to by the Selling Fund and the Buying Fund. - - The Selling Fund will transfer all of its assets to the Buying Fund and, in exchange, the Buying Fund will assume the Selling Fund's stated liabilities. - - The Buying Fund will issue Class A, B, C, I and Y shares to the Selling Fund in an amount equal to the value of the assets of Classes A, B, C, I and Y that it receives from the Selling Fund, less the liabilities assumed by the Buying Fund in the transaction. These shares will immediately be distributed by the Selling Fund to its shareholders in proportion to their holdings in the Selling Fund. As a result, shareholders of the Selling Fund will become Class A, B, C, I or Y shareholders of the Buying Fund. - - Neither the Selling Fund nor the shareholders of the Selling Fund will pay any sales charge in connection with the Reorganization. - - The net asset value of the Selling Fund and the Buying Fund will be computed as of 3:00 p.m. Central time, on the closing date. - - After the Reorganization, the Selling Fund will be terminated. CONDITIONS TO CLOSING THE REORGANIZATION The completion of the Reorganization is subject to certain conditions described in the Agreement, including: - - The Selling Fund will have declared and paid a dividend that will distribute all of the Fund's taxable income, if any, to the shareholders of the Fund for the taxable years ending at or prior to the closing. - - The Funds will have received any approvals, consents or exemptions from the SEC or any regulatory body necessary to carry out the Reorganization. - - A registration statement on Form N-14 will have been filed with the SEC and declared effective. - - The shareholders of the Selling Fund will have approved the Agreement. - - The Selling Fund will have received an opinion of tax counsel that the proposed Reorganization will result in no gain or loss being recognized by any shareholder. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 20 <Page> TERMINATION OF THE AGREEMENT The Agreement and the transactions contemplated by it may be terminated and abandoned by resolutions of the Board of the Selling Fund or the Buying Fund at any time prior to closing. In the event of a termination, there will be no liability for damages on the part of either the Selling Fund or the Buying Fund or the Board members, officers or shareholders of the Selling Corporation or of the Buying Corporation. TAX STATUS OF THE REORGANIZATION The Reorganization is expected to be tax-free for federal income tax purposes and will not take place unless the Selling Fund and the Buying Fund receive a satisfactory opinion of tax counsel (which opinion will be based on certain factual representations and certain customary assumptions), to the effect that, although not entirely free from doubt, on the basis of existing provisions of the Internal Revenue Code of 1986, as amended (the "Code"): - - The transfer of the Selling Fund's assets to the Buying Fund in exchange for Class A, B, C, I and Y shares of the Buying Fund and the assumption of the Selling Fund's liabilities, followed by the distribution of those Class A, B, C, I and Y shares to the Selling Fund's shareholders and the termination of the Selling Fund will be a "reorganization" within the meaning of Section 368(a)(1) of the Code, and the Selling Fund and the Buying Fund will each be a "party to the reorganization" within the meaning of Section 368(b) of the Code. - - Under Section 361 of the Code, no gain or loss will be recognized by the Selling Fund upon the transfer of all of its assets to the Buying Fund or on the distribution by the Selling Fund of Class A, B, C, I and Y shares of the Buying Fund to Selling Fund shareholders in liquidation. - - Under Section 354 of the Code, the shareholders of the Selling Fund will not recognize gain or loss upon the exchange of their Class A, B, C, I or Y shares of the Selling Fund solely for Buying Fund Class A, B, C, I or Y shares as part of the Reorganization. - - Under Section 358 of the Code, the aggregate basis of the Class A, B, C, I or Y shares of the Buying Fund that a Selling Fund shareholder receives in the Reorganization will be the same as the aggregate basis of the Class A, B, C, I or Y shares of the Selling Fund exchanged therefor. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 21 <Page> - - Under Section 1223(1) of the Code, the holding period for the Class A, B, C, I or Y shares of the Buying Fund that a Selling Fund shareholder receives in the Reorganization will include the period for which he or she held the Class A, B, C, I or Y shares of the Selling Fund exchanged therefor, provided that on the date of the exchange he or she held such Selling Fund shares as capital assets. - - Under Section 1032 of the Code, no gain or loss will be recognized by the Buying Fund upon the receipt of the Selling Fund's assets solely in exchange for the issuance of Buying Fund's Class A, B, C, I and Y shares to the Selling Fund and the assumption of all of the Selling Fund's liabilities by the Buying Fund. - - Under Section 362(b) of the Code, the Buying Fund's tax basis in the assets that the Buying Fund receives from the Selling Fund will be the same as the Selling Fund's tax basis in those assets immediately prior to the transfer. - - Under Section 1223(2) of the Code, the Buying Fund's holding periods in the assets received from the Selling Fund will include the Selling Fund's holding periods in such assets. - - Under Section 381 of the Code, the Buying Fund will succeed to and take into account the items of the Selling Fund described in Section 381(c) of the Code, subject to the conditions and limitations specified in Sections 381, 382, 383 and 384 of the Code and Regulations thereunder. Tax counsel will express no view with respect to the effect of the Reorganization on any transferred asset as to which any unrealized gain or loss is required to be recognized at the end of a taxable year (or on the termination or transfer thereof) under federal income tax principles. Prior to the closing of the Reorganization, the Selling Fund will, and the Buying Fund may, declare a distribution to shareholders, which together with all previous distributions, will have the effect of distributing to shareholders all of its investment company taxable income (computed without regard to the deduction for dividends paid) and net realized capital gains (after reduction by any available capital loss carryforwards), if any, through the closing of the Reorganization. These distributions will be taxable to shareholders. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 22 <Page> A fund's ability to carry forward capital losses and use them to offset future gains may be limited. First, one fund's "pre-acquisition losses" (including capital loss carryforwards, net current-year capital losses, and unrealized losses that exceed certain thresholds) cannot be used to offset unrealized gains in another fund that are "built in" at the time of the reorganization and that exceed certain thresholds ("non-de minimis built-in gains") for five tax years. Second, a portion of a fund's pre-acquisition losses may become unavailable to offset any gains at all. Third, any remaining pre-acquisition losses will offset capital gains realized after a reorganization and thus will reduce subsequent capital gain distributions to a broader group of shareholders than would have been the case absent such reorganization. Therefore, in certain circumstances, former shareholders of a fund may pay taxes sooner, or pay more taxes, than they would have had a reorganization not occurred. The Buying Fund's ability to carry forward its own pre-acquisition losses, if any, and use them to offset future gains will technically be limited as a result of the Reorganization due to the effect of loss limitation rules under applicable tax law. The effect of this limitation will depend on the losses and gains in each fund at the time of the Reorganization. For example, based on data as of Aug. 31, 2005, such limitation would have had no impact at all as neither the Buying Fund nor the Selling Fund had pre-Reorganization "net losses" (i.e., capital loss carryforwards as of its last fiscal year end as adjusted by year-to-date realized gains or losses and all net unrealized gains). For five years beginning after the closing date, the combined fund will not be allowed to offset gains "built in" to either fund at the time of the Reorganization against capital losses (including capital loss carryforwards) built in to the other fund. The realized and unrealized gains and losses of each Fund at the time of the Reorganization will determine the extent to which the combining Funds' respective losses, both realized and unrealized, will be available to reduce gains realized by the combined Fund following the Reorganization, and consequently the extent to which the combined Fund may be required to distribute gains to its shareholders earlier than would have been the case absent the Reorganization. This description of the federal income tax consequences of the Reorganization does not take into account your particular facts and circumstances. Consult your own tax adviser about the effect of state, local, foreign, and other tax laws. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 23 <Page> REASONS FOR THE PROPOSED REORGANIZATION AND BOARD DELIBERATIONS The Board believes that the proposed Reorganization will be advantageous to Selling Fund shareholders based on its considerations of the following matters: - - TERMS AND CONDITIONS OF THE REORGANIZATION. The Board considered the terms and conditions of the Reorganization as described in the previous paragraphs. - - TAX CONSEQUENCES. The Board considered the tax-free nature of the Reorganization. - - CONTINUITY OF INVESTMENT. The Board took into account the fact that, because the Selling Fund is substantially larger than the Buying Fund, the portfolio of the combined Fund, following the Reorganization, will be represented mostly by the current holdings of the Selling Fund. The Board also considered the compatibility of the two portfolios. While the Board recognized that the two Funds have different investment objectives (e.g., the Selling Fund, unlike the Buying Fund, seeks current income in addition to capital growth) and different approaches (as half of the Selling Fund's portfolio is managed using a different strategy than that employed for the Buying Fund), the Board took into account the general compatibility of the two portfolios in that both Funds invest primarily in a portfolio of large cap stocks and are managed using the same benchmarks. The Board also took into account, in this regard, that like the Selling Fund (and consistent with the income element of its objective), a large percentage of the Buying Fund's portfolio consists of dividend-paying stocks. - - EXPENSE RATIOS. The Board considered the relative expenses of the Funds and took into account that, as of the end of each Fund's most recent fiscal year, the expense ratios for the Buying Fund were higher than the expense ratios for the Selling Fund. For example, the Selling Fund's expense ratio for Class A shares as of Sept. 30, 2005 fiscal year end, adjusted to reflect current fees after giving effect to the performance incentive adjustment was 0.93% (0.95%, before giving effect to any performance incentive adjustment). The Buying Fund's expense ratio for Class A shares as of July 31, 2005, its most recent fiscal year end, adjusted to reflect current fees, was capped at 1.25%, before giving effect to any performance adjustment (1.27% after giving effect to the performance incentive adjustment). The Board accorded weight to the fact that, if shareholders approve the Reorganization, the investment manager has agreed to cap total expenses of the Buying Fund as follows: (i) for a period of 12 months following implementation of the Reorganization, the investment manager and its affiliates will waive fees or cap expenses of the Buying Fund sufficient to keep total expenses within 5 basis points (0.05%) of the Selling Fund's expense ratio at the time of the Reorganization; and (ii) for a period of 5 years following the 12-month period, the investment RIVERSOURCE STOCK FUND -- PROXY STATEMENT 24 <Page> manager and its affiliates will waive fees or cap expenses so that the Buying Fund's expense ratio is at or below the median expense ratio of comparable funds sold through investment advisers in the Buying Fund's Lipper peer group. (For purposes of these calculations, the expense ratio will be determined prior to application of the performance incentive adjustment.) The Board further accorded weight to the fact that the Buying Fund's current expense ratio was below the median expense ratio of its Lipper peer group and that, as a result, the current pricing of the Fund was in line with the "pricing philosophy" of the RiverSource Fund family. - - ECONOMIES OF SCALE. The Board believes that by combining the Funds, the shareholders continue to have available to them a Fund with a portfolio of larger capitalization stocks, but can at the same time take advantage of the economies of scale associated with a larger fund. Furthermore, a larger fund should have an enhanced ability to effect portfolio transactions on more favorable terms and should have greater investment flexibility. For example, expenses such as audit expenses and accounting expenses that are charged on a per fund basis will be reduced. In addition, if shareholders approve the Reorganization, the investment manager and its affiliates have agreed to cap total expenses of the Buying Fund as discussed in the paragraph on Expense Ratios. - - COSTS. The Board considered the fact that the investment manager has agreed to bear all solicitation expenses in order to achieve shareholder approval of the Reorganization and to bear any other costs of effecting the Reorganization (i.e., the filing, closing and other costs of consummating the transaction). - - DILUTION. The Board considered the fact that the Reorganization will not dilute the interests of the current shareholder because it would be effected on the basis of the relative net asset values per share of the Selling Fund and Buying Fund, respectively. Thus, a Class A shareholder of the Selling Fund will receive Class A shares of the Buying Fund equal in value to his or her Class A shares in the Selling Fund. - - PERFORMANCE AND OTHER CONSIDERATIONS. The Board considered the relative performance records of the Funds. The Board took into account the better track record of the Buying Fund. The Board recognized that the Buying Fund's track record covers a brief period because the Fund has only been in operation since April 2003. While the Board was cognizant of the fact that the Buying Fund's past performance is no guarantee of its future results, it did consider that the better track record of the Buying Fund (albeit a brief history), could help attract more assets into the combined Fund and therefore could help stem the stream of outflows that have been experienced by the Selling Fund. The Board considered that reduced outflows or increased inflows could help the Selling Fund shareholders achieve further economies of scale (see "Economies of Scale"above). RIVERSOURCE STOCK FUND -- PROXY STATEMENT 25 <Page> The Board also considered the fact that the Funds are in the same Lipper and Morningstar categories and that half of the Selling Fund portfolio is managed in an identical way to the Buying Fund. In light of these commonalities, the Board accorded weight to the investment manager's belief that, absent the Reorganization, the two Funds would be likely to compete against each other for the same investor base and, thus, could draw assets away from the other Fund. The Reorganization should allow for a concentrated selling effort thereby potentially benefiting both Funds. The Board further took into account the investment manager's belief that the Selling Fund, as a stand-alone Fund, was unlikely to experience any growth in assets as a result of investor inflows (based particularly on the recent rates of monthly outflows). - - POTENTIAL BENEFITS TO THE INVESTMENT MANAGER AND ITS AFFILIATES. The Board also considered the potential benefits from the Reorganization that could be realized by the investment manager and its affiliates. The Board recognized that the potential benefits to the investment manager consist principally of the elimination of expenses incurred in duplicative efforts to administer separate funds. The Board also noted, however, that shareholders of the Selling Fund will benefit over time from any decrease in overall operating expense ratios resulting from the proposed Reorganization. BOARDS' DETERMINATIONS After considering the factors described above and other relevant information, at a meeting held on Nov. 9-10, 2005, the Selling Fund Board members, including a majority of the independent Board members, found that participation in the Reorganization is in the best interests of the Selling Fund and that the interests of existing shareholders of the Fund will not be diluted as a result of the Reorganization. The Board of Directors of the Buying Fund approved the Agreement at a meeting held on Nov. 9-10, 2005. Among other factors, the Board members considered the terms of the Agreement, the provisions intended to avoid the dilution of shareholder interests and the anticipated tax consequences of the Reorganization. The Board also took into account that the Buying Fund expense ratio will decline as a result of Reorganization. The Board found that participation in the Reorganization is in the best interests of the Buying Fund and that the interests of existing shareholders of the Buying Fund will not be diluted as a result of the Reorganization. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 26 <Page> RECOMMENDATION AND VOTE REQUIRED The Board recommends that shareholders approve the proposed Agreement. The Agreement must be approved by a majority of the voting power of all shares entitled to vote. If the Agreement is not approved, the Board will consider what further action should be taken. If shareholders approve the Reorganization, it will take place shortly after the shareholder meeting. During the period between the shareholder meeting and the merger, or if the merger is not approved, it will be important for the Fund to have a properly elected Board and an IMS Agreement that has been approved by shareholders. Therefore, the Board is recommending that shareholders approve the other proposals. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 27 <Page> PROPOSAL 2.

RIVERSOURCE STOCK FUND -- PROXY STATEMENT 31 <Page> BOARD COMMITTEES. The Board has several committees that facilitate the work of the Board. The Executive Committee has authority to act for the full Board between meetings. The Contracts Committee receives and analyzes reports covering the level and quality of services provided under contracts with the fund and advises the Board regarding actions taken on these contracts during the annual review process. The Investment Review Committee considers investment management policies and strategies; investment performance; risk management techniques; and securities trading practices and reports areas of concern to the Board. The Board Effectiveness Committee's charter, Exhibit E, requires it to make recommendations regarding nominees based on criteria approved by the Board. All members of the Committee are independent. Nominee recommendations are based on a matrix of skill sets, experience, and geographical location and each nominee must have a background that demonstrates the ability to furthering the interest of all shareholders. The Committee will consider recommendations from shareholders who write to the Boards and provide detailed information about a candidate. All candidates are processed in the same fashion; first by evaluating a candidate's detailed information against the criteria; then interviewing those candidates who best fill vacancies identified by the matrix. You may write the Board by addressing a letter to Arne H. Carlson, the independent Chair of the Board or any other independent member of the Board, at Board Services Corporation, 901 Marquette Avenue South, Suite 2810, Minneapolis, MN 55402-3268. However, do not address letters to this address if you are requesting some action regarding your investments. In order to avoid any delay in processing a request regarding an investment, please address these requests to 70100 Ameriprise Financial Center, Minneapolis, MN 55474. The Joint Audit Committee, made up entirely of independent Board members, operates under a written charter, Exhibit F. The Joint Audit Committee meets with the independent auditors, internal auditors and corporate officers to review and discuss audited financial statements, reports, issues, and compliance matters. This Committee reports significant issues to the Board and makes recommendations to the independent Board members regarding the selection of the independent public accountant. More information regarding this Committee and the fund's independent auditor is found in Section C. During the 12-month period ended Sept. 30, 2005, the Board met 8 times, Executive 2 times, Contracts 7 times, Investment Review 5 times, Board Effectiveness 6 times and Joint Audit 4 times. All Board members had 100% attendance except for Mr. Simpson who had 82% attendance due to serious illness in January 2005. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 32 <Page> SHAREHOLDER COMMUNICATIONS WITH THE BOARD. Shareholders may communicate directly with the Board by sending correspondence to Arne H. Carlson, Chair of the Board, RiverSource Funds, 901 Marquette Avenue South, Suite 2810, Minneapolis, MN 55402-3268. Correspondence to specific individual Board members also may be directed to the same address. Account-specific correspondence should be directed to RiverSource Funds, 70100 Ameriprise Financial Center, Minneapolis, MN 55474. BOARD MEMBER COMPENSATION. The following table shows the total compensation received by each Board member from all of the RiverSource Funds. The funds do not pay retirement benefits to Board members. Under a Deferred Compensation Plan, independent Board members may defer receipt of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of one or more designated RiverSource funds. TABLE A-5.

Mr. Carlson's total compensation was $373,750. Board member compensation is a combination of a base fee and meeting fees. Because the spin-off of Ameriprise Financial from American Express Company necessitated 5 additional meetings, each Board member was paid $23,500 to cover those additional meetings. That cost, which is included in the aggregate compensation shown above, was borne by Ameriprise Financial. Ms. Blatz, Mr. Laikind and Ms. Pryor were not Board members prior to Sept. 30, 2005 and therefore are not included in the table. (b) Includes portion of compensation deferred in the amount of $889 from the Fund. (c) Includes portion of compensation deferred in the amount of $60,371 from the RiverSource funds. (d) Includes portion of compensation deferred in the amount of $54,839 from the RiverSource funds.

Officers are paid by Ameriprise Financial, RiverSource Investments or Board Services Corporation. During the last fiscal year, no officer earned more than $60,000 from any fund. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 34 <Page> PROPOSAL 3: APPROVE OR REJECT AN AMENDMENT TO THE ARTICLES OF INCORPORATION REFERENCE TO THE "FUND" IN THIS PROPOSAL IS A REFERENCE TO STOCK. The Fund is a Minnesota corporation and operates under an organizational document called the articles of incorporation. The articles of incorporation set forth various provisions relating to the authority of the fund to conduct business and the governance of the fund. The Board has approved, and recommends that shareholders approve, a proposal to amend the fund's articles of incorporation (the "Articles"). The fund's investments and investment policies will not change by virtue of the adoption of the amendment to the Articles. A. MINIMUM ACCOUNT VALUE Generally, shareholders must invest at least $2,000 to open a fund account. Section 7 of the Articles currently provides that the fund may redeem shares if an account falls below a value of $1,000. Small accounts can be costly to maintain and this provision allows the Board to close accounts that no longer meet the fund's minimum standards. However, the current provision does not allow the Board to redeem accounts if the value is higher than $1,000. In the future, there may be circumstances in which a minimum account value higher than $1,000 is in the best interest of the fund and its shareholders. As a consequence, the Board recommends that the Articles be amended to eliminate the reference to a specific dollar amount. As proposed, the amended Articles will permit the Board to establish a minimum account value that will be disclosed in the fund prospectus. The Board will be able to change the minimum account value without further action by shareholders. If the change is approved, the Articles will be amended as follows ([underline] additions are underlined [/underline] , [strikethrough] deletions are lined through)[/strikethrough] : Article III, Section 7 will be amended to read: Section 7. The Fund may redeem the shares of a shareholder if the amount invested is less than [strikethrough] $1,000 [/strikethrough] [underline] an amount determined by the Board of Directors and set forth in the current Fund prospectus. [/underline] RIVERSOURCE STOCK FUND -- PROXY STATEMENT 35 <Page> B. NAME CHANGE. Historically the name of the fund has reflected the name of the investment manager. Since 1999, the name of the fund has included the letters AXP, which is an abbreviated form of the name American Express. In August 2005, American Express Financial Corporation ("AEFC"), the fund's investment manager changed its name to Ameriprise Financial, Inc. in anticipation of its spin off from American Express Company, its parent company. On Oct. 1, 2005, Ameriprise Financial transferred responsibility for the fund's investment advisory services to its wholly owned subsidiary, RiverSource Investments. The Board made a corresponding change to the name of the fund by substituting the name RiverSource for AXP. The fund is part of a corporation made up of one fund. The name of the corporate entity can be changed only with approval of the shareholders of all the underlying funds that make up the corporation. The Board recommends that the name of the corporate entity also be changed to include the name RiverSource instead of AXP. The change to the name of the corporation is shown in the table below. This is the first shareholder meeting since the spin off of the investment manager and the first opportunity for shareholders to consider a name change for the corporation. TABLE A-7. PROPOSED NAME OF CORPORATION <Table> <Caption> CURRENT NAME OF CORPORATION PROPOSED NAME OF CORPORATION AXP Stock Series, Inc. RiverSource Stock Series, Inc. </Table> BOARD RECOMMENDATION AND VOTE REQUIRED. The Board recommends that you vote to approve the amendments to the Articles. The changes require the approval by a majority of the shares voted at the meeting. The changes will be effective when the amendments are filed with the Secretary of State's office. This filing is expected to occur shortly after the shareholder meeting. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 36 <Page> PROPOSAL 4: APPROVE OR REJECT AN INVESTMENT MANAGEMENT SERVICES AGREEMENT WITH RIVERSOURCE INVESTMENTS, LLC REFERENCE TO THE "FUND" IN THIS PROPOSAL IS A REFERENCE TO STOCK. The fund pays fees to RiverSource Investments under an Investment Management Services Agreement (the "IMS Agreement") for investment management services. The services include providing the personnel, equipment and office facilities necessary for the management of the fund's assets. Subject to the oversight of the Board and consistent with the fund's investment policies, the investment manager decides what securities to buy, hold or sell. The investment manager also executes buy and sell orders and provides research and statistical data to support investment management activities. The Fund is part of a master/feeder structure. In this structure, the fund invests all of its assets in a master fund (the "portfolio") with the same policies as the fund. For purposes of this discussion, the portfolio is referred to as a "fund". INVESTMENT MANAGER. On Sept. 30, 2005, Ameriprise Financial became a publicly traded company and on Oct. 1, 2005 transferred the investment management functions and IMS Agreement to RiverSource Investments, a wholly-owned subsidiary. While these transfers did not cause a termination of the IMS Agreement, the Board determined that it would be prudent to give shareholders an opportunity to vote on the arrangement and the changes described below. SUMMARY OF KEY CHANGES A. PERFORMANCE INCENTIVE ADJUSTMENT ("PIA"). The management fee includes a PIA as part of the fee calculation. The PIA calculation is based on the performance of the fund compared to the performance index of a group of comparable mutual funds compiled by Lipper, Inc. ("Lipper"). The proposed change clarifies the circumstances under which the Board may change an index for purposes of calculating the PIA. B. STANDARD OF CARE. For all funds, the investment manager will be held to a higher standard of care than under the current IMS Agreement. C. CONFIDENTIALITY. The proposed IMS Agreement contains an explicit acknowledgement from the fund that the investment manager may be prevented from divulging or acting upon certain confidential information learned in connection with its activities, including the provision of investment advice to clients other than the fund. In addition, the proposed IMS Agreement contains additional confidentiality provisions prohibiting the fund from disclosing to third parties any information or advice furnished by the investment manager to the fund, unless required by law or necessary to provide services to the fund. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 37 <Page> D. AMENDMENTS. The proposed IMS Agreement clarifies that, as permitted under applicable law, the parties may make non-material amendments or modifications without obtaining shareholder approval. TERMS OF THE CURRENT IMS AGREEMENT. The fee the fund pays to RiverSource Investments for its services under the current IMS Agreement is based on the net assets of the fund and decreases as the size of the fund increases. The complete fee schedule for the fund and other similar funds managed by RiverSource Investments is found in Section C. The fund also pays its taxes, brokerage commission and nonadvisory expenses, which include custodian fees; audit and certain legal fees; fidelity bond premiums; registration fees for shares; consultant fees; Board compensation; corporate filing fees; organizational expenses; expenses incurred in connection with lending portfolio securities; and other expenses properly payable by the fund, approved by the Board. Section C includes information on the date of the current IMS Agreement, the date it was last approved by shareholders and the reason why it was submitted to shareholders at that time. A. PERFORMANCE INCENTIVE ADJUSTMENT ("PIA") CALCULATION. The management fee includes a PIA as part of the fee. The adjustment is based on the performance of the fund compared to the performance of a Lipper Index. The proposed modification does not change the IMS Agreement but clarifies the circumstances where the Board may change the index for purposes of this calculation. The provision in the current IMS Agreement will be modified to read as follows ([underline] additions are underlined /[underline], [strikethrough] deletions are lined through [/strikethrough] ): If an Index ceases to be published for a period of more than 90 days, changes in any material respect, otherwise becomes impracticable [underline] or, in the discretion of the Board, is no longer appropriate[/underline] to use for purposes of a performance incentive adjustment, [underline] for example, if Lipper reclassifies the Fund from one peer group to another, the Board may take action it deems appropriate and in the best interests of shareholders, including: (1) discontinuance of the performance incentive adjustment until such time as it approves a substitute index, or (2) adoption of a methodology to transition to a substitute index it has approved.[/underline] [strikethrough] no adjustment will be made until such time as the Board approves a substitute index.[/strikethrough] The PIA is determined by measuring the difference in the fund's performance from an appropriate Lipper Index over a rolling 12-month period. Should the Board approve the use of a substitute index, it may transition to the substitute index by introducing it gradually over time, to avoid unintended swings in the PIA. B. STANDARD OF CARE. The proposed IMS Agreement revises the standard of care to provide that, except for bad faith, intentional misconduct or negligence in RIVERSOURCE STOCK FUND -- PROXY STATEMENT 38 <Page> regard to the performance of its duties pursuant to the agreement, neither the investment manager, nor any of its respective directors, officers, partners, principals, employees, or agents shall be liable for any acts or omissions or for any loss suffered by the fund or its shareholders or creditors. This means that the investment manager is held to a higher standard of care. C. CONFIDENTIALITY. The current IMS Agreement contains an acknowledgement by the fund that the investment manager renders investment advice and other services to other investment companies and persons which may or may not have investment policies and investments similar to those of the fund. The proposed IMS Agreement adds an explicit acknowledgement from the fund that the investment manager may not be free to divulge to the fund or act, for the benefit of the fund, upon confidential information learned in connection with its activities, including the provision of investment advice to clients other than the fund. The current IMS Agreement is silent on the fund's obligation to refrain from divulging confidential information. The proposed IMS Agreement includes a new provision that prohibits the fund from disclosing to third parties any information or advice furnished to the fund by the investment manager, unless required by law or necessary to provide services to the fund. D. AMENDMENTS. The current IMS Agreement does not address whether shareholder approval must be obtained before non-material amendments or modifications may be made. The proposed IMS Agreement includes a new provision clarifying that the parties may make non-material amendments or modifications without obtaining shareholder approval, as permitted under applicable law. BASIS FOR RECOMMENDATION OF THE BOARD Following announcement of the spin-off of Ameriprise Financial from American Express Company, the Board and Ameriprise Financial agreed to review and revise, where appropriate, the terms of all contracts, including the IMS Agreement, pursuant to which Ameriprise Financial or its affiliates provides services to the fund. Each year, the Board determines whether to continue the IMS Agreement for the fund and, in doing so, evaluates the quality and level of service received under the IMS Agreement and the costs associated with those services. Accordingly, in March and April of each year, Ameriprise Financial prepares detailed reports for the Board, which include data prepared by independent organizations, to assist the Board in making this determination. The Board accords considerable weight to the work, deliberations and conclusions of its committees in determining whether to continue the IMS Agreement. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 39 <Page> After thorough review of the reports and data provided at a meeting held in person on April 14, 2005, the Board, including all of its independent members, determined that the quality and level of advisory services provided pursuant to the IMS Agreement for the fund were satisfactory and that fees were fair and reasonable. However, in light of the announced plans of the spin-off, the Board approved continuation of the IMS Agreement for only an interim period ending on the later of (i) the effective date of the spin-off; or (ii) the approval of a new investment management services agreement with Ameriprise Financial (or its subsidiaries) by the shareholders of the fund, but in no event for a period longer than one year. While it was expected that the spin-off would not result in an "assignment" of an IMS Agreement under the 1940 Act and, therefore, would not cause the termination of the IMS Agreement according to its terms, Schulte Roth & Zabel LLP, retained as independent counsel to the Board, advised the Board that the legal question of whether the spin-off would result in an assignment turns on a highly fact-sensitive analysis. Therefore, the Board determined, as a matter of prudence, to proceed as if the IMS Agreement would terminate as a result of the spin-off. Accordingly, the Board determined to renew the IMS Agreement for the interim period only and to consider a new IMS Agreement for the fund prior to the spin-off. For the six months following the April 2005 meeting, the Board and its committees evaluated whether to approve a proposed IMS Agreement for the fund with post-spin Ameriprise Financial (or its subsidiary). Schulte Roth & Zabel LLP assisted the Board in fulfilling its statutory and other responsibilities associated with the spin-off and the resulting consideration of new contracts, including the proposed IMS Agreement. As a key step in this process, independent counsel sent, on behalf of the independent members of the Board, a detailed and expansive request for information to American Express Company and Ameriprise Financial, seeking specified information thought to be relevant to the Board's consideration of the proposed contracts with post-spin Ameriprise Financial. The Board and its committees were provided with a wealth of written and oral information intended to assist them in considering the proposed contracts, including the proposed IMS Agreement. Furthermore, in connection with the Board's considerations as to whether post-spin Ameriprise Financial, as an independent entity, would be capable of continuing to provide a high quality of services to the funds, the Board's independent members retained their own financial adviser, Credit Suisse First Boston LLC ("CSFB"). At the Board's requests, CSFB provided various written materials and oral presentations analyzing the capital adequacy of Ameriprise Financial. The costs of independent counsel and CSFB and of additional meetings of the Board were borne by Ameriprise Financial as part of the commitment of American Express Company to ensure a complete and thorough review of the proposed spin-off and its effect on the services provided by Ameriprise Financial and its subsidiaries. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 40 <Page> During the course of the six-month period following the April 2005 meeting, the Board and its committees met at five in-person meetings to consider the information provided by American Express Company, Ameriprise Financial, independent counsel and CSFB. At an in-person meeting held on Sept. 8, 2005, based on all of the information provided as well as the deliberations occurring at that meeting and the previous meetings held since the announcement of the spin-off, the Board, including all of its independent members, approved each of the new contracts, including the proposed IMS Agreement. On Oct. 1, 2005, pursuant to an agreement between the Fund and Ameriprise Financial, the IMS Agreement was transferred to RiverSource Investments, a wholly-owned subsidiary of Ameriprise Financial. For these reasons, the Board, including all of its independent members, recommends that you approve the proposed IMS Agreement for the fund. THE BOARD'S SPECIFIC CONSIDERATIONS RELATING TO THE PROPOSED IMS AGREEMENT. In carrying out its legal responsibilities associated with the consideration of he proposed IMS Agreements, the Board evaluated the following four factors: (i) the nature, extent and quality of services to be provided by RiverSource Investments; (ii) the investment performance of the fund; (iii) the costs of the services to be provided and the profits to be realized by Ameriprise Financial; and (iv) the extent to which economies of scale would be realized as the fund grows and whether the fee level reflects these economies of scale for the benefit of fund investors. NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY POST-SPIN AMERIPRISE FINANCIAL (AND ITS SUBSIDIARIES). The Board recognized that only a few months had passed since its April 2005 determination to renew the IMS Agreement for the fund and that in April 2005, it had concluded that the nature, extent and quality of services provided by Ameriprise Financial were satisfactory and consistent with those that would be expected for a fund family of the size of the RiverSource funds. However, the Board also recognized that this assessment must be supplemented with an evaluation of whether the spin-off or other factors would result in any changes to the advisory services currently provided to the funds. In this regard, the Board focused its evaluation on the following factors potentially impacting the nature, extent and quality of advisory services to be provided by RiverSource Investments: (i) Ameriprise Financial's projected capital structure and capital adequacy as a stand-alone entity; (ii) its legal and regulatory risks; (iii) its ability to retain and attract personnel; and (iv) its ability to successfully rebrand its products and services. Based on extensive presentations and reports by Ameriprise Financial, CSFB and independent counsel, the Board concluded that the proposed capital structure (which includes certain indemnification commitments made by American Express Company) should enable RiverSource Investments to continue to provide a high quality of advisory RIVERSOURCE STOCK FUND -- PROXY STATEMENT 41 <Page> services to the funds. In making this determination, the Board took into account representations by management of Ameriprise Financial that projected capital levels would allow Ameriprise Financial (including RiverSource Investments) to continue to meet its legal and compliance responsibilities, build its distribution network, pursue technological upgrades, make capital commitments necessary to retain and attract key personnel devoted to legal and compliance responsibilities, portfolio management and distribution, and pursue smaller asset management acquisitions to help grow its business. The Board accorded significant weight to CSFB's confirmation as to the reasonableness of the foregoing representations. The Board also considered the fact that there were no expected departures of key personnel involved in the portfolio management, operations and marketing of the funds as a result of the announcement of the spin-off. The Board concluded that, based on all of the materials and information provided (and with the assistance of independent counsel), post-spin Ameriprise Financial (including RiverSource Investments) would be in a position to continue to provide a high quality of investment management services to the funds. INVESTMENT PERFORMANCE. The Board next focused on investment performance. The Board reviewed reports documenting the fund's performance over one-, three- and/or five-year periods, as well as the entire period during which its current portfolio manager has managed the fund, and compared the performance to relevant Lipper and market indices. The Board took into account its considerations in April 2005, in particular that investment performance over the past three years was below median, but that Ameriprise Financial has taken steps to address the underperformance and that the performance over the past year was above median. The Board also considered that it has received monthly performance reports for the funds. The Board and its committees concluded in September 2005 that there have been no significant deviations from April's overall performance data. COST OF SERVICES PROVIDED. The Board evaluated comparative fees and the costs of services to be provided under the current and proposed IMS Agreements, including fees charged by Ameriprise Financial (including RiverSource Investments and other subsidiaries) to its institutional clients and paid to subadvisers. The Board studied RiverSource Investments' effort (its "pricing philosophy") to set most funds' total expense ratios at or below the median expense ratio of their peer group. The Board considered that the fund's management fees would not change under the proposed IMS Agreement. The Board also took into account the effect of the proposed performance incentive adjustment on the advisory fee. In this regard, the Board took into account its past determinations regarding the appropriateness of: (i) the use of the RIVERSOURCE STOCK FUND -- PROXY STATEMENT 42 <Page> appropriate index for the fund for the comparison of performance; (ii) the methodology for determining when the Board may change an index used to calculate the performance incentive adjustment; (iii) the periods used for averaging the fund's assets and computing investment performance; and (iv) the length of the period over which performance is computed. The Board next considered the expected profitability to RiverSource Investments and its affiliates derived from their relationship with the fund, recalling the April 2005 determination that the profitability level was appropriate. The Board noted that projected profitability of RiverSource Investments would allow it to operate effectively and, at the same time, reinvest in its businesses. The Board also considered that the proposed changes in advisory fees for certain RiverSource funds as well as the mergers of certain funds would result in revenue gains, while taking into account that these increases would not materially alter profit margins due to expected increases in costs associated with the spin-off, particularly rebranding and separation. CSFB also reported that Ameriprise Financial's projected level of return on equity was generally reasonable in light of the returns on equity of its industry competitors. In evaluating profitability, the Board also considered the benefits Ameriprise Financial obtains through the use of commission dollars paid on portfolio transactions for the fund and from other business relationships that result from managing the fund. The Board also considered the fees charged by Ameriprise Financial to its institutional clients and paid to subadvisers, noting the differences in services provided in each case. In light of these considerations, the Board concluded that projected profitability levels were appropriate. ECONOMIES OF SCALE. The Board also considered the breakpoints in fees that would be triggered as the net asset levels of the fund grew and the extent to which shareholders would benefit from such growth. The Board observed that the fee schedule under the proposed IMS Agreement would continue to provide breakpoints similar to those in place pursuant to the current IMS Agreement. Accordingly, the Board concluded that the proposed IMS Agreement provides adequate opportunity for shareholders to realize benefits as fund assets grow. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 43 <Page> OTHER CONSIDERATIONS. In addition, the Board accorded weight to the fact that, under the proposed IMS Agreement, RiverSource Investments is held to a higher standard of care than under the current IMS Agreement. The Board also noted Ameriprise Financial's commitment to a culture that adheres to ethical business practice, assigns accountability to senior management and seeks to identify conflicts and propose appropriate action to minimize the risks posed by the conflicts. Furthermore, the Board recognized that it was not limited to considering management's proposed contracts. In this regard, the Board evaluated the circumstances under which it would consider the retention of an investment adviser different from RiverSource Investments (or its subsidiaries). The Board concluded, based on its consultation with independent counsel, that pursuing the retention of a different adviser was not necessary, primarily because, in its best judgment, RiverSource Investments continues to be basically the same organization (from a functional and managerial standpoint) as it was prior to the spin-off. The Board reasoned that shareholders purchased shares of the fund with an expectation that the current investment advisory organization would be servicing the fund. As a result of all of the foregoing, the Board determined that the fees to be paid under the proposed IMS Agreement were fair and reasonable in light of services proposed to be provided. BOARD RECOMMENDATION AND VOTE REQUIRED. For the foregoing reasons, the Board recommends that shareholders of the fund approve the proposed IMS Agreement. The proposed IMS Agreement must be approved by the lesser of (a) a majority of the fund's outstanding shares or (b) 67% of the shares voted at the meeting, so long as more than 50% of the shares actually vote. If shareholders approve the proposed IMS Agreement, it will take effect shortly after the shareholder meeting. If the proposed IMS Agreement is not approved, the Board will consider appropriate steps to take. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 44 <Page> SECTION B -- PROXY VOTING AND SHAREHOLDER MEETING INFORMATION REFERENCE TO THE "FUND" IN THIS SECTION IS A REFERENCE TO STOCK. VOTING. You are entitled to vote based on your total dollar interest in the fund. Each dollar is entitled to one vote. For those of you who cannot come to the meeting, the Board is asking permission to vote for you. The shares will be voted as you instruct either by mail, telephone or internet. Signed proxy cards returned without instructions will be voted in favor of all proposals. In voting for Board members, you may vote all of your shares cumulatively. This means that you have the right to give each nominee an equal number of votes or divide the votes among the nominees as you wish. You have as many votes as the number of dollars you own on the record date, multiplied by the number of Board members to be elected. If you elect to withhold authority for any individual nominee or nominees, you may do so by marking the box labeled "For All Except," and by striking the name of any excepted nominee, as is further explained on the card itself. If you do withhold authority, the proxies will not vote shares equivalent to the proportionate number applicable to the names for which authority is withheld. All votes count toward a quorum, regardless of how they are voted (For, Against or Abstain). Broker non-votes will be counted toward a quorum but not toward the approval of any proposals. (Broker non-votes are shares for which the underlying owner has not voted and the broker holding the shares does not have authority to vote.) If your shares are held in an IRA account with Ameriprise Trust Company as custodian, you have the right to instruct the IRA Custodian how to vote those shares. The IRA Custodian will vote any shares for which it has not received voting instructions in proportionately the same manner -- either For, Against, or Abstain -- as other fund shareholders have voted. MASTER/FEEDER FUNDS. Stock currently is part of a master/feeder structure. The feeder fund seeks its investment objective by investing its assets in a master fund with the same policies. The master fund invests in and manages the securities. Immediately prior to the Reorganization, the Board intends to withdraw the fund's assets from the master fund. REVOKING YOUR PROXY. If you change your mind after you vote and you can attend the meeting, simply inform the Secretary at the meeting that you will be voting your shares in person. Also, if you change your mind after you vote, but cannot attend the meeting, you may change your vote or revoke it by mail, telephone or internet. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 45 <Page> SIMULTANEOUS MEETINGS. The meeting will be held simultaneously with meetings of other RiverSource mutual funds. Each proposal will be voted on separately by shareholders of a corporation or by shareholders of a fund or by a class of shares of the fund where appropriate. If any shareholder objects to the holding of simultaneous meetings, the shareholder may move for an adjournment of his or her fund's meeting to a time immediately after the simultaneous meetings so that a meeting of that fund may be held separately. If a shareholder makes this motion, the persons named as proxies will take into consideration the reasons for the objection in deciding whether to vote in favor of the adjournment. SOLICITATION OF PROXIES. The Board is asking for your vote and for you to vote as promptly as possible. The investment manager will pay the expenses of the solicitation. Supplementary solicitations may be made by mail, telephone, electronic means or personal contact. SHAREHOLDER PROPOSALS. No proposals were received from shareholders. The RiverSource funds are not required to hold regular meetings of shareholders each year. However, meetings of shareholders are held from time to time and proposals of shareholders that are intended to be presented at future shareholder meetings must be submitted in writing to the RiverSource funds in reasonable time prior to the solicitation of proxies for the meeting. DISSENTERS' RIGHT OF APPRAISAL. Under Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act, Selling Fund shareholders are entitled to assert dissenters' rights in connection with the Reorganization and obtain payment of the "fair value" of their shares, provided that they comply with the requirements of Minnesota law. A copy of the relevant provisions is attached as Exhibit C. Notwithstanding the provisions of Minnesota law, the SEC has taken the position that use of state appraisal procedures by a mutual fund would be a violation of Rule 22c-1, the forward pricing rule, under the 1940 Act. This rule states that no mutual fund may redeem its shares other than at net asset value next computed after receipt of a request for redemption. It is the SEC's position that Rule 22c-1 supersedes appraisal provisions in state statutes. In the interest of ensuring equal valuation for all shareholders, dissenters' rights will be determined in accordance with the SEC's interpretation. As a result, if any shareholder elects to exercise dissenters' rights under Minnesota law, the Selling Fund intends to submit this question to a court of competent jurisdiction. In that event, a dissenting shareholder would not receive any payment until the end of the court proceeding. RIVERSOURCE STOCK FUND -- PROXY STATEMENT 46 <Page> OTHER BUSINESS. The Board does not know at this time of any other business to come before the meetings. If something does come up, the proxies will use their best judgment to vote for you on the matter. ADJOURNMENT. In the event that not enough votes are received by the time scheduled for the meeting, the persons named as proxies may move for one or more adjournments of the meeting for a period of not more than 120 days in the aggregate to allow further solicitation of shareholders on the proposals. Any adjournment requires the affirmative vote of a majority of the voting power of the shares present at the meeting. The persons named as proxies will vote in favor of adjournment those shares they are entitled to vote that have voted in favor of the proposals. They will vote against any adjournment those shares that have voted against the proposals. The investment manager will pay the costs of any additional solicitation and of any adjourned meeting. A shareholder vote may be taken on one or more of the items in this proxy statement prior to adjournment if sufficient votes have been received.

THE FUND'S INDEPENDENT REGISTERED PUBLIC ACCOUNTANT. The 1940 Act provides that every registered investment company must be audited at least once each year by independent registered public accountants selected by a majority of the independent Board members. The Selling Fund's Board has selected KPMG LLP to be the Fund's independent registered public accountant for the current fiscal year. KPMG LLP, in accordance with Independence Standards Board Standard No. 1 ("ISB No. 1"), has confirmed in writing to the Board's Joint Audit Committee that they are independent accountants with respect to the Fund. The independent accountants examine the financial statements for the Fund that are set forth in the annual report to shareholders and provide other requested non-audit and tax-related services to the Fund. The Joint Audit Committee reviewed and discussed the audited financial statements with RiverSource Investments and reviewed with KPMG LLP the matters required to be discussed by SAS 61 (for example, methods used to account for significant unusual transactions). The Joint Audit Committee does not consider other non-audit services provided by KPMG LLP to be incompatible with maintaining the independence of KPMG LLP in its audits of the Fund, taking into account representations from KPMG LLP, in accordance with ISB No. 1, regarding its independence from the Fund and its related entities. Representatives of KPMG LLP are expected to be present at the meeting. They will be given the opportunity to make a statement to shareholders and are expected to be available to respond to any questions that may be raised at the meeting. JOINT AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES. Pursuant to the pre-approval requirements of the Sarbanes-Oxley Act of 2002, all services to be performed by KPMG LLP for the Fund; the Fund's investment adviser; and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the Fund, must be pre-approved by the Joint Audit Committee.

Ogg Vice President AXP Growth Series, Inc. on behalf of RiverSource Disciplined Equity Fund By ----------------------------------- Leslie L. Ogg Vice President The undersigned is a party to this Agreement for purposes of Section 3c and 10 only. RiverSource Investments, LLC By ----------------------------------- Paula R. Meyer Senior Vice President - Mutual Funds RIVERSOURCE STOCK FUND -- PROXY STATEMENT A.12 <Page> EXHIBIT B REFERENCE TO THE "FUND" IN THIS EXHIBIT IS A REFERENCE TO DISCIPLINED EQUITY. MATTERS SUBJECT TO APPROVAL AT REGULAR MEETING OF BUYING FUND In addition to voting on proposals to elect Board members, to amend the Articles of Incorporation, and to approve the IMS Agreement, Buying Fund shareholders will consider the following: APPROVE OR REJECT CHANGES IN FUNDAMENTAL INVESTMENT POLICIES The fund has some investment policies that are fundamental. This means the policies can be changed only with the approval of shareholders. RiverSource Investments recommended to the Board that certain of those policies be modified in order to standardize the policies for all RiverSource funds and to eliminate unnecessary limitations. RiverSource Investments believes that increased standardization will help to promote operational efficiencies and facilitate monitoring of compliance with fundamental investment policies. Adoption of a new or revised policy is not intended to change current investment techniques employed for the fund. The Board recommends the following changes to the fund's fundamental investment policies: A. DIVERSIFICATION The Board recommends that the fund's fundamental policy with respect to diversification be revised to give the fund the maximum flexibility permitted by the 1940 Act. The Board recommends that shareholders vote to replace the fund's current fundamental investment policy with the following policy (additional or revised language is underlined): The fund will not invest more than 5% of its total assets in securities of any company, government, or political subdivision thereof, except the limitation will not apply to investments in securities issued or guaranteed by the U.S. government, its agencies or instrumentalities or other investment companies, and except that up to 25% of the fund's total assets may be invested without regard to this 5% limitation. RIVERSOURCE STOCK FUND -- PROXY STATEMENT B.1 <Page> The percentage limits in the proposed policy are required under the 1940 Act. The amended policy makes one change from the current policy: subject to applicable 1940 Act requirements, it would permit the fund to invest without limit in the securities of other investment companies. Pursuant to an exemptive order granted by the Securities and Exchange Commission (the "SEC"), the fund may invest up to 25% of its total assets in a non-publicly offered money market fund managed by RiverSource Investments (the "cash pool fund"). The cash pool fund is not expected to pay investment advisory, management, or transfer agent fees, although it may do so subject to the conditions of the SEC order and Board approval. The cash pool fund will incur minimal costs for services, such as custodian and auditor fees. The investment manager anticipates that making use of the cash pool fund will benefit the fund by enhancing the efficiency of cash management and by providing increased short-term investment opportunities. If the proposal is approved, the cash pool fund is expected to serve as a principal option for managing the cash positions of the fund. Future amendments to the fund's fundamental diversification policy would continue to require shareholder approval. B. LENDING The Board recommends that the fund's fundamental policies with respect to lending be replaced with the following policy: The Fund will not lend securities or participate in an interfund lending program if the total of all such loans would exceed 33 1/3% of the Fund's total assets except this fundamental investment policy shall not prohibit the Fund from purchasing money market securities, loans, loan participation or other debt securities, or from entering into repurchases agreements. Currently the fund has two policies with respect to lending. One policy limits lending of portfolio securities to 30% of net assets and the other policy limits cash loans to 5% of total assets. In addition, the fund has a policy prohibiting loans to the investment manager, or to board members and officers of the investment manager or the fund. This third policy simply states a prohibition of the 1940 Act and the fund is not required to declare this policy as a fundamental policy. It is proposed that all three of these policies be superseded by the policy stated above. RIVERSOURCE STOCK FUND -- PROXY STATEMENT B.2 <Page> The proposal is not expected to materially affect the operation of the fund. However, the proposed policy would clarify that the fund can participate in an interfund borrowing and lending program with other RiverSource Funds, subject to the requirements of an SEC exemptive order. A fund may only borrow money for temporary purposes and may not borrow for leverage or investment purposes. Appropriate safeguards will be implemented to assure that the fund will not be disadvantaged by making loans to affiliated funds. The proposed policy also would confirm the fund's ability to invest in direct debt instruments such as loans and loan participations, which are interests in amounts owed to another party by a company, government or other borrower. These types of securities may have additional risks beyond conventional debt securities because they may provide less legal protection for the fund, or there may be a requirement that the fund supply additional cash to a borrower on demand. Finally, the adoption of the proposed investment policy will advance the goal of standardizing investment policies. C. BORROWING The Board recommends that the fund's fundamental policy with respect to borrowing be replaced with the following policy: The fund may not borrow money, except for temporary purposes (not for leveraging or investment) in an amount not exceeding 33 1/3% of its total assets (including the amount borrowed) less liabilities (other than borrowings) immediately after the borrowings. Funds typically borrow money to meet redemptions in order to avoid forced, unplanned sales of portfolio securities. This technique allows RiverSource Investments greater flexibility in managing the fund's cash flow. The current policy limits borrowing to "emergency or extraordinary purposes". In order to avoid debate over what constitutes emergency or extraordinary purposes, it is proposed to revise the policy to reflect that the purposes, whatever the circumstances, must be temporary. The fund may not use borrowing for leverage or for investment purposes. In addition, the policy for certain funds includes a prohibition on borrowing "property". The Board recommends that this prohibition be deleted in order to standardize investment policies. RIVERSOURCE STOCK FUND -- PROXY STATEMENT B.3 <Page> BOARD RECOMMENDATION AND VOTE REQUIRED. The Board recommends that shareholders approve the proposed changes. Changes in fundamental policies must be approved by the lesser of (a) a majority of the fund's outstanding shares or (b) 67% of the shares voted at the meeting, so long as more than 50% of the shares actually vote. If the any of the proposed changes is not approved, the fund will continue to operate under its current policy. RIVERSOURCE STOCK FUND -- PROXY STATEMENT B.4 <Page> EXHIBIT C MINNESOTA BUSINESS CORPORATION ACT SECTIONS 302A.471 AND 302A.473 Minnesota law requires that we provide you with a copy of the state law on dissenters' rights. Notwithstanding the provisions of the law set out below, the SEC has taken the position that use of state appraisal procedures by a registered mutual fund such as the Fund would be a violation of Rule 22c-1, the forward pricing rule, under the 1940 Act. As a result, if any shareholder elects to exercise dissenters' rights under Minnesota law, the Fund intends to submit this question to a court of competent jurisdiction. In that event, a dissenting shareholder would not receive any payment until the end of the court proceeding. 302A.471. RIGHTS OF DISSENTING SHAREHOLDERS SUBDIVISION 1. ACTIONS CREATING RIGHTS. A shareholder of a corporation may dissent from, and obtain payment for the fair value of the shareholder's shares in the event of, any of the following corporate actions: (a) An amendment of the articles that materially and adversely affects the rights or preferences of the shares of the dissenting shareholder in that it: (1) alters or abolishes a preferential right of the shares; (2) creates, alters, or abolishes a right in respect of the redemption of the shares, including a provision respecting a sinking fund for the redemption or repurchase of the shares; (3) alters or abolishes a preemptive right of the holder of the shares to acquire shares, securities other than shares, or rights to purchase shares or securities other than shares; (4) excludes or limits the right of a shareholder to vote on a matter, or to cumulate votes, except as the right may be excluded or limited through the authorization or issuance of securities of an existing or new class or series with similar or different voting rights; except that an amendment to the articles of an issuing public corporation that provides that section 302A.671 does not apply to a control share acquisition does not give rise to the right to obtain payment under this section; (b) A sale, lease, transfer, or other disposition of all or substantially all of the property and assets of the corporation, but not including a transaction permitted without shareholder approval in section 302A.661, subdivision 1, or a disposition in dissolution described in section 302A.725, subdivision 2, or a disposition pursuant to an order of a court, or a disposition for cash on terms requiring that all or substantially all of the net proceeds of disposition be distributed to the shareholders in accordance with their respective interests within one year after the date of disposition; RIVERSOURCE STOCK FUND -- PROXY STATEMENT C.1 <Page> (c) A plan of merger, whether under this chapter or under chapter 322B, to which the corporation is a party, except as provided in subdivision 3, and except for a plan of merger adopted under section 302A.626; (d) A plan of exchange, whether under this chapter or under chapter 322B, to which the corporation is a party as the corporation whose shares will be acquired by the acquiring corporation, except as provided in subdivision 3; or (e) Any other corporate action taken pursuant to a shareholder vote with respect to which the articles, the bylaws, or a resolution approved by the board directs that dissenting shareholders may obtain payment for their shares. SUBDIVISION 2. BENEFICIAL OWNERS. (a) A shareholder shall not assert dissenters' rights as to less than all of the shares registered in the name of the shareholder, unless the shareholder dissents with respect to all the shares that are beneficially owned by another person but registered in the name of the shareholder and discloses the name and address of each beneficial owner on whose behalf the shareholder dissents. In that event, the rights of the dissenter shall be determined as if the shares as to which the shareholder has dissented and the other shares were registered in the names of different shareholders. (b) The beneficial owner of shares who is not the shareholder may assert dissenters' rights with respect to shares held on behalf of the beneficial owner, and shall be treated as a dissenting shareholder under the terms of this section and section 302A.473, if the beneficial owner submits to the corporation at the time of or before the assertion of the rights a written consent of the shareholder. SUBDIVISION 3. RIGHTS NOT TO APPLY. (a) Unless the articles, the bylaws, or a resolution approved by the board otherwise provide, the right to obtain payment under this section does not apply to a shareholder of (1) the surviving corporation in a merger with respect to shares of the shareholder that are not entitled to be voted on the merger or (2) the corporation whose shares will be acquired by the acquiring corporation in a plan of exchange with respect to shares of the shareholder that are not entitled to be voted on the plan of exchange and are not exchanged in the plan of exchange. (b) If a date is fixed according to section 302A.445, subdivision 1, for the determination of shareholders entitled to receive notice of and to vote on an action described in subdivision 1, only shareholders as of the date fixed, and beneficial owners as of the date fixed who hold through shareholders, as provided in subdivision 2, may exercise dissenters' rights. SUBDIVISION 4. OTHER RIGHTS. The shareholders of a corporation who have a right under this section to obtain payment for their shares do not have a right at RIVERSOURCE STOCK FUND -- PROXY STATEMENT C.2 <Page> law or in equity to have a corporate action described in subdivision 1 set aside or rescinded, except when the corporate action is fraudulent with regard to the complaining shareholder or the corporation. 302A.473. PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS SUBDIVISION 1. DEFINITIONS. (a) For purposes of this section, the terms defined in this subdivision have the meanings given them. (b) "Corporation" means the issuer of the shares held by a dissenter before the corporate action referred to in section 302A.471, subdivision 1 or the successor by merger of that issuer. (c) "Fair value of the shares" means the value of the shares of a corporation immediately before the effective date of the corporate action referred to in section 302A.471, subdivision 1. (d) "Interest" means interest commencing five days after the effective date of the corporate action referred to in section 302A.471, subdivision 1, up to and including the date of payment, calculated at the rate provided in section 549.09 for interest on verdicts and judgments. SUBDIVISION 2. NOTICE OF ACTION. If a corporation calls a shareholder meeting at which any action described in section 302A.471, subdivision 1 is to be voted upon, the notice of the meeting shall inform each shareholder of the right to dissent and shall include a copy of section 302A.471 and this section and a brief description of the procedure to be followed under these sections. SUBDIVISION 3. NOTICE OF DISSENT. If the proposed action must be approved by the shareholders, a shareholder who is entitled to dissent under section 302A.471 and who wishes to exercise dissenters' rights must file with the corporation before the vote on the proposed action a written notice of intent to demand the fair value of the shares owned by the shareholder and must not vote the shares in favor of the proposed action. SUBDIVISION 4. NOTICE OF PROCEDURE; DEPOSIT OF SHARES. (a) After the proposed action has been approved by the board and, if necessary, the shareholders, the corporation shall send to all shareholders who have complied with subdivision 3 and to all shareholders entitled to dissent if no shareholder vote was required, a notice that contains: (1) The address to which a demand for payment and certificates of certificated shares must be sent in order to obtain payment and the date by which they must be received; (2) Any restrictions on transfer of uncertificated shares that will apply after the demand for payment is received; RIVERSOURCE STOCK FUND -- PROXY STATEMENT C.3 <Page> (3) A form to be used to certify the date on which the shareholder, or the beneficial owner on whose behalf the shareholder dissents, acquired the shares or an interest in them and to demand payment; and (4) A copy of section 302A.471 and this section and a brief description of the procedures to be followed under these sections. (b) In order to receive the fair value of the shares, a dissenting shareholder must demand payment and deposit certificated shares or comply with any restrictions on transfer of uncertificated shares within 30 days after the notice required by paragraph (a) was given, but the dissenter retains all other rights of a shareholder until the proposed action takes effect. SUBDIVISION 5. PAYMENT; RETURN OF SHARES. (a) After the corporate action takes effect, or after the corporation receives a valid demand for payment, whichever is later, the corporation shall remit to each dissenting shareholder who has complied with subdivisions 3 and 4 the amount the corporation estimates to be the fair value of the shares, plus interest, accompanied by: (1) The corporation's closing balance sheet and statement of income for a fiscal year ending not more than 16 months before the effective date of the corporate action, together with the latest available interim financial statements; (2) An estimate by the corporation of the fair value of the shares and a brief description of the method used to reach the estimate; and (3) A copy of section 302A.471 and this section, and a brief description of the procedure to be followed in demanding supplemental payment. (b) The corporation may withhold the remittance described in paragraph (a) from a person who was not a shareholder on the date the action dissented from was first announced to the public or who is dissenting on behalf of a person who was not a beneficial owner on that date. If the dissenter has complied with subdivisions 3 and 4, the corporation shall forward to the dissenter the materials described in paragraph (a), a statement of the reason for withholding the remittance, and an offer to pay to the dissenter the amount listed in the materials if the dissenter agrees to accept that amount in full satisfaction. The dissenter may decline the offer and demand payment under subdivision 6. Failure to do so entitles the dissenter only to the amount offered. If the dissenter makes demand, subdivision 7 and 8 apply. (c) If the corporation fails to remit payment within 60 days of the deposit of certificates or the imposition of transfer restrictions on uncertificated shares, it shall return all deposited certificates and cancel all transfer restrictions. However, the corporation may again give notice under subdivision 4 and require deposit or restrict transfer at a later time. RIVERSOURCE STOCK FUND -- PROXY STATEMENT C.4 <Page> SUBDIVISION 6. SUPPLEMENTAL PAYMENT; DEMAND. If a dissenter believes that the amount remitted under subdivision 5 is less than the fair value of the shares plus interest, the dissenter may give written notice to the corporation of the dissenter's own estimate of the fair value of the shares, plus interest, within 30 days after the corporation mails the remittance under subdivision 5, and demand payment of the difference. Otherwise, a dissenter is entitled only to the amount remitted by the corporation. SUBDIVISION 7. PETITION; DETERMINATION. If the corporation receives a demand under subdivision 6, it shall, within 60 days after receiving the demand, either pay to the dissenter the amount demanded or agreed to by the dissenter after discussion with the corporation or file in a court a petition requesting that the court determine the fair value of the shares, plus interest. The petition shall be filed in the county in which the registered office of the corporation is located, except that a surviving foreign corporation that receives a demand relating to the shares of a constituent domestic corporation shall file the petition in the county in this state in which the last registered office of the constituent corporation was located. The petition shall name as parties all dissenters who have demanded payment under subdivision 6 and who have not reached agreement with the corporation. The corporation shall, after filing the petition, serve all parties with a summons and copy of the petition under the rules of civil procedure. Nonresidents of this state may be served by registered or certified mail or by publication as provided by law. Except as otherwise provided, the rules of civil procedures apply to this proceeding. The jurisdiction of the court is plenary and exclusive. The court may appoint appraisers, with powers and authorities the court deems proper, to receive evidence on and recommend the amount of the fair value of the shares. The court shall determine whether the shareholder or shareholders in question have fully complied with the requirements of this section, and shall determine the fair value of the shares, taking into account any and all factors the court finds relevant, computed by any method or combination of methods that the court, in its discretion, sees fit to use, whether or not used by the corporation or by a dissenter. The fair value of the shares as determined by the court is binding on all shareholders, wherever located. A dissenter is entitled to judgment in cash for the amount by which the fair value of the shares as determined by the court, plus interest, exceeds the amount, if any, remitted under subdivision 5, but shall not be liable to the corporation for the amount, if any, by which the amount, if any, remitted to the dissenter under subdivision 5 exceeds the fair value of the shares as determined by the court, plus interest. RIVERSOURCE STOCK FUND -- PROXY STATEMENT C.5 <Page> SUBDIVISION 8. COSTS; FEES; EXPENSES. (a) The court shall determine the costs and expenses of a proceeding under subdivision 7, including the reasonable expenses and compensation of any appraisers appointed by the court, and shall assess those costs and expenses against the corporation, except that the court may assess part or all of those costs and expenses against a dissenter whose action in demanding payment under subdivision 6 is found to be arbitrary, vexatious, or not in good faith. (b) If the court finds that the corporation has failed to comply substantially with this section, the court may assess all fees and expenses of any experts or attorneys as the court deems equitable. These fees and expenses may also be assessed against a person who has acted arbitrarily, vexatiously, or not in good faith in bringing the proceeding, and may be awarded to a party injured by those actions. (c) The court may award, in its discretion, fees and expenses to an attorney for the dissenters out of the amount awarded to the dissenters, if any.

(Ameriprise Financial) (formerly American Express Financial Corporation), was spun off to shareholders of its parent corporation, American Express Company (American Express), and is now a separate public company, trading under the ticker symbol AMP. Ameriprise Financial provides administrative services to the Fund and is the parent company of the Fund's investment manager, RiverSource Investments, LLC; the Fund's distributor, Ameriprise Financial Services, Inc. (formerly American Express Financial Advisors, Inc.); the Fund's transfer agent, RiverSource Service Corporation (formerly American Express Client Service Corporation); and the Fund's custodian, Ameriprise Trust Company (formerly American Express Trust Company). On Oct. 1, 2005, the Fund changed its name, such that it no longer is branded AXP(R). The Fund now bears the RiverSource(SM) brand. Ameriprise Financial and its subsidiaries are no longer affiliated with American Express. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.2 <Page> THE FUND OBJECTIVE RiverSource Disciplined Equity Fund (the Fund) seeks to provide shareholders with long-term capital growth. Because any investment involves risk, achieving this objective cannot be guaranteed. PRINCIPAL INVESTMENT STRATEGIES Under normal market conditions, at least 80% of the Fund's net assets are invested in equity securities of companies listed on U.S. exchanges with market capitalizations greater than $5 billion at the time of purchase. The Fund will provide shareholders with at least 60 days' notice of any change in the 80% policy. In pursuit of the Fund's objective, the investment manager (RiverSource Investments, LLC) will choose equity investments by employing proprietary quantitative methods based on sophisticated statistical analysis. The universe of stocks from which the investment manager selects the Fund's investments primarily will be those included in the Fund's benchmark, the S&P 500. Through extensive analysis of the domestic equity markets, the investment manager has identified characteristics of certain stocks that have historically outperformed their benchmarks. The Fund will hold both growth and value stocks. Characteristics used to select stocks for the Fund include: - - Superior growth characteristics such as: - strong earnings growth, - positive earnings that exceed expectations published by third-party business analysts, - consistency of earnings, and - strong positive price trend. - - Superior value characteristics based on analysis of current stock prices relative to estimates of future prices. In selecting the stocks for the Fund's portfolio, the investment manager employs a rigorous process for evaluating the relationship between the risk associated with each security and its potential for positive returns. This process includes factors such as: - - Limits on positions relative to the benchmark through overweighting or underweighting. - - Limits on sector and industry allocations relative to the benchmark. - - Limits on size of holdings relative to market liquidity. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.3 <Page> PRINCIPAL RISKS This Fund is designed for investors with above-average risk tolerance. Please remember that with any mutual fund investment you may lose money. Principal risks associated with an investment in the Fund include: ACTIVE MANAGEMENT RISK. The Fund is actively managed and its performance therefore will reflect in part the ability of the portfolio managers to make investment decisions that are suited to achieving the Fund's investment objective. Due to its active management, the Fund could underperform other mutual funds with similar investment objectives. ISSUER RISK. An issuer may perform poorly, and therefore, the value of its stocks and bonds may decline. Poor performance may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, or other factors. MARKET RISK. The market value of securities may fall or fail to rise. Market risk may affect a single issuer, sector of the economy, industry, or the market as a whole. The market value of securities may fluctuate, sometimes rapidly and unpredictably. This risk is generally greater for small and mid-sized companies, which tend to be more vulnerable to adverse developments. In addition, focus on a particular style, for example, investment in growth or value securities, may cause the Fund to underperform other mutual funds if that style falls out of favor with the market. The quantitative methodology employed by the investment manager has been extensively tested using historical securities market data, but has only recently begun to be used to manage open-end mutual funds. There can be no assurance that the methodology will enable the Fund to achieve its objective. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.4 <Page> PAST PERFORMANCE The following bar chart and table provide some illustration of the risks of investing in the Fund by showing, respectively: - - how the Fund's performance has varied for each full calendar year shown on the bar chart, and - - how the Fund's average annual total returns compare to recognized indexes shown on the table. Both the bar chart and the table assume that all distributions have been reinvested. The performance of different classes varies because of differences in sales charges and other fees and expenses. How the Fund has performed in the past (before and after taxes) does not indicate how the Fund will perform in the future. Performance reflects any fee waivers/expense caps in effect for the periods reported. In the absence of such fee waivers/expense caps, performance would have been lower. See "Fees and Expenses" for any current fee waivers/expense caps. BAR CHART. Class A share information is shown in the bar chart; the sales charge for Class A shares is not reflected in the bar chart. TABLE. The table shows total returns from hypothetical investments in Class A, Class B, Class C and Class Y shares of the Fund. These returns are compared to the indexes shown for the same periods. For purposes of the performance calculation in the table we assumed: - - the maximum sales charge for Class A shares, - - sales at the end of the period and deduction of the applicable contingent deferred sales charge (CDSC) for Class B and Class C shares, - - no sales charge for Class Y shares, and - - no adjustments for taxes paid by an investor on the reinvested income and capital gains. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.5 <Page> AFTER-TAX RETURNS After-tax returns are shown only for Class A shares. After-tax returns for the other classes will vary. After-tax returns are calculated using the highest historical individual federal marginal income tax rate and do not reflect the impact of state and local taxes. Actual after-tax returns will depend on your tax situation and most likely will differ from the returns shown in the table. If you hold your shares in a tax-deferred account, such as a 401(k) plan or an IRA, the after-tax returns do not apply to you since you will not incur taxes until you begin to withdraw from your account. The return after taxes on distributions for a period may be the same as the return before taxes for the same period if there were no distributions or if the distributions were small. The return after taxes on distributions and sale of Fund shares for a period may be greater than the return before taxes for the same period if there was a tax loss realized on sale of Fund shares. The benefit of the tax loss (since it can be used to offset other gains) may result in a higher return. [CHART] CLASS A SHARE PERFORMANCE (BASED ON CALENDAR YEARS) <Table> 2004 +9.96% </Table> During the period shown in the bar chart, the highest return for a calendar quarter was +9.77% (quarter ended Dec. 31, 2004) and the lowest return for a calendar quarter was -3.05% (quarter ended Sept. 30, 2004). The 5.75% sales charge applicable to Class A shares of the Fund is not reflected in the bar chart; if reflected, returns would be lower than those shown. The performance of other classes may vary from that shown because of differences in expenses. The Fund's Class A year-to-date return at June 30, 2005 was -0.15%. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.6 <Page> AVERAGE ANNUAL TOTAL RETURNS (FOR PERIODS ENDED DEC. 31, 2004) <Table> <Caption> SINCE 1 YEAR INCEPTION RiverSource Disciplined Equity: Class A Return before taxes +3.64% +15.85%(a) Return after taxes on distributions +2.89% +14.94%(a) Return after taxes on distributions and sale of fund shares +2.65% +13.16%(a) Class B Return before taxes +4.16% +16.92%(a) Class C Return before taxes +8.16% +19.05%(a) Class Y Return before taxes +10.26% +20.23%(a) S&P 500 Index (reflects no deduction for fees, expenses or taxes) +10.88% +20.32%(b) Lipper Large-Cap Core Funds Index +8.29% +17.00%(b) </Table> (a) Inception date is April 24, 2003. (b) Measurement period started May 1, 2003. The Standard & Poor's 500 Index (S&P 500 Index), an unmanaged index of common stocks, is frequently used as a general measure of market performance. The index reflects reinvestment of all distributions and changes in market prices, but excludes brokerage commissions or other fees. The Lipper Large-Cap Core Funds Index includes the 30 largest large-cap core funds tracked by Lipper Inc. The index's returns include net reinvested dividends. The Fund's performance is currently measured against this index for purposes of determining the performance incentive adjustment. See "Fund Management and Compensation" for more information. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.7 <Page> FEES AND EXPENSES Fund investors pay various expenses. The table below describes the fees and expenses that you may pay if you buy and hold shares of the Fund. Expenses are based on the Fund's most recent fiscal year, adjusted to reflect current fees.

See "Sales Charges." (b) For Class A purchases over $1,000,000 on which no sales charge is assessed, a 1% sales charge may apply if you sell your shares within one year after purchase. (c) Includes the impact of a performance incentive adjustment fee that increased the management fee by 0.02% for the most recent fiscal year. The index against which the Fund's performance is measured for purposes of determining the performance incentive adjustment is the Lipper Large-Cap Core Funds Index. See "Fund Management and Compensation" for more information. (d) Other expenses include an administrative services fee, a transfer agency fee, a custody fee and other nonadvisory expenses and, for Class Y shares, a shareholder service fee. (e) The investment manager and its affiliates have contractually agreed to waive certain fees and to absorb certain expenses until July 31, 2006, 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 expenses, before giving effect to any performance incentive adjustment, will not exceed 1.25% for Class A; 2.04% for Class B; 2.06% for Class C and 1.06% for Class Y. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.8 <Page> EXAMPLES These examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. These examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. These examples also assume that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: <Table> <Caption> 1 YEAR 3 YEARS 5 YEARS 10 YEARS Class A(a) $697 $ 973 $1,270 $2,113 Class B $709(b) $1,063(b) $1,343(b) $2,272(c) Class C $311(b) $ 665 $1,145 $2,472 Class Y $110 $ 367 $ 645 $1,438 </Table> (a) Includes a 5.75% sales charge.

(b) Based on conversion of Class B shares to Class A shares in the ninth year of ownership. OTHER INVESTMENT STRATEGIES AND RISKS OTHER INVESTMENT STRATEGIES. In addition to the principal investment strategies previously described, the Fund may invest in other securities and may use other investment strategies that are not principal investment strategies. Additionally, the Fund may use derivatives (financial instruments where the value depends upon, or is derived from, the value of something else) such as futures, options and forward contracts, to produce incremental earnings, to hedge existing positions or to increase flexibility. Just as with securities in which the Fund invests directly, derivatives are subject to a number of risks, including market, liquidity, interest rate and credit risk. In addition, a relatively small price movement in the underlying security, currency or index may result in a substantial gain or loss for the Fund using derivatives. Even though the Fund's policies permit the use of derivatives in this manner, the portfolio managers are not required to use derivatives. For more information on strategies and RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.9 <Page> holdings, and the risks of such strategies, including other derivative instruments that the Fund may use, see the Fund's Statement of Additional Information (SAI) and its annual and semiannual reports. UNUSUAL MARKET CONDITIONS. During unusual market conditions, the Fund may temporarily invest more of its assets in money market securities than during normal market conditions. Although investing in these securities would serve primarily to avoid losses, this type of investing also could prevent the Fund from achieving its investment objective. During these times, the portfolio managers may make frequent securities trades that could result in increased fees, expenses and taxes, and decreased performance. PORTFOLIO TURNOVER. Trading of securities may produce capital gains, which are taxable to shareholders when distributed. Active trading may also increase the amount of commissions or mark-ups paid to broker-dealers that the Fund pays when it buys and sells securities. The Fund's historical portfolio turnover rate, which measures how frequently the Fund buys and sells investments, is shown in the "Financial Highlights." SECURITIES TRANSACTION COMMISSIONS. Securities transactions involve the payment by the Fund of brokerage commissions to broker-dealers, on occasion as compensation for research or brokerage services (commonly referred to as "soft dollars"), as the portfolio managers buy and sell securities for the Fund in pursuit of its objective. A description of the policies governing the Fund's securities transactions and the dollar value of brokerage commissions paid by the Fund are set forth in the SAI. The brokerage commissions set forth in the SAI do not include implied commissions or mark-ups (implied commissions) paid by the Fund for principal transactions (transactions made directly with a dealer or other counterparty), including most fixed income securities and certain derivatives. In addition, brokerage commissions do not reflect other elements of transaction costs, including the extent to which the Fund's purchase and sale transactions may cause the market to move and change the market price for an investment. Although brokerage commissions and implied commissions are not reflected in the expense table under "Fees and Expenses," they are reflected in the total return of the Fund. DIRECTED BROKERAGE. The Fund's Board of Directors (Board) has adopted a policy prohibiting the investment manager, or any subadviser, from considering sales of shares of the Fund as a factor in the selection of broker-dealers through which to execute securities transactions. Additional information regarding securities transactions can be found in the SAI. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.10 <Page> FUND MANAGEMENT AND COMPENSATION INVESTMENT MANAGER RiverSource Investments, LLC (the investment manager or RiverSource Investments), 200 Ameriprise Financial Center, Minneapolis, Minnesota 55474, is the investment manager to the RiverSource funds, and is a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Ameriprise Financial is a financial planning and financial services company that has been offering solutions for clients' asset accumulation, income management and protection needs for more than 110 years. In addition to managing investments for all of the RiverSource funds, RiverSource Investments manages investments for itself and its affiliates. For institutional clients, RiverSource Investments and its affiliates provide investment management and related services, such as separate account asset management, institutional trust and custody, and employee benefit plan administration, as well as other investment products. For all of its clients, RiverSource Investments seeks to allocate investment opportunities in an equitable manner over time. See the SAI for more information. The Fund pays RiverSource Investments a fee for managing its assets. Under the Investment Management Services Agreement (Agreement), the fee for the most recent fiscal year was 0.62% of the Fund's average daily net assets, including an adjustment under the terms of a performance incentive arrangement. The adjustment is computed by comparing the Fund's performance to the performance of an index of comparable funds published by Lipper Inc. The index against which the Fund's performance is currently measured for purposes of the performance incentive adjustment is the Lipper Large-Cap Core Funds Index. In certain circumstances, the Fund's Board may approve a change in the index. The maximum adjustment (increase or decrease) is 0.12% of the Fund's average net assets on an annual basis. Under the Agreement, the Fund also pays taxes, brokerage commissions, and nonadvisory expenses. A discussion regarding the basis for the Board approving the Agreement is available in the Fund's most recent shareholder report.

These services include administrative, accounting, treasury, and other services. Fees paid by the Fund for these services are included under "Other expenses" in the expense table under "Fees and Expenses." RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.12 <Page> CUSTODY SERVICES. Ameriprise Trust Company, 200 Ameriprise Financial Center, Minneapolis, Minnesota 55474 (the custodian or Ameriprise Trust Company), provides custody services to all but a limited number of the RiverSource funds, for which U.S. Bank National Association provides custody services. In addition, Ameriprise Trust Company is paid for certain transaction fees and out-of-pocket expenses incurred while providing services to the funds. Fees paid by the Fund for these services are included under "Other expenses" in the expense table under "Fees and Expenses." DISTRIBUTION SERVICES. Ameriprise Financial Services, Inc., 70100 Ameriprise Financial Center, Minneapolis, Minnesota 55474 (the distributor or Ameriprise Financial Services), provides underwriting and distribution services to the RiverSource funds. Under the Distribution Agreement and related distribution and shareholder servicing plan(s), the distributor receives distribution and shareholder servicing fees. The distributor pays a portion of these fees to financial advisors and retains a portion of these fees to support its distribution and shareholder servicing activity. For third party sales, the distributor re-allows a portion of these fees to the financial intermediaries that sell Fund shares and provide services to shareholders, and retains a portion of these fees to support its distribution and shareholder servicing activity. Fees paid by the Fund for these services are set forth under "Distribution (12b-1) fees" in the expense table under "Fees and Expenses." More information on how these fees are used is set forth under "Investment Options" and in the SAI. The distributor also administers any sales charges paid by an investor at the time of purchase or at the time of sale (deferred sales charge). See "Shareholder Fees (fees paid directly from your investment)" under "Fees and Expenses" for the scheduled sales charge of each share class. See "Buying and Selling Shares" for variations in the scheduled sales charges, and for how these sales charges are used by the distributor. See "Other Investment Strategies and Risks" for Fund policy regarding directed brokerage. TRANSFER AGENCY SERVICES. RiverSource Service Corporation, 70100 Ameriprise Financial Center, Minneapolis, Minnesota 55474 (the transfer agent or RiverSource Service Corporation), provides or compensates others to provide transfer agency services to the RiverSource funds. The RiverSource funds pay the transfer agent a fee, which varies by share class, as set forth in the SAI and reimburses the transfer agent for its out-of-pocket expenses incurred while providing these transfer agency services to the funds. Fees paid by the Fund for these services are included under "Other expenses" in the expense table under "Fees and Expenses." RiverSource funds are primarily sold through Ameriprise Financial Services which is allocated a portion of these fees for providing services to Fund shareholders. RiverSource Service Corporation may also pay a portion of these fees to other financial intermediaries that provide sub-recordkeeping and other services to Fund shareholders. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.13 <Page> The SAI provides additional information about the services provided and the fee schedules for the agreements set forth above. PAYMENTS TO FINANCIAL INTERMEDIARIES RiverSource Investments and its affiliates may make additional cash payments out of their own resources to financial intermediaries, such as broker-dealers, banks, qualified plan administrators and recordkeepers, or other institutions, including inter-company allocation of resources to affiliated broker-dealers such as Ameriprise Financial Services (financial intermediaries) in connection with the sale of shares of the Fund and/or the provision of services to the Fund or its shareholders. These payments may create an incentive for the financial intermediary, its employees or registered representatives to recommend or sell shares of the Fund to its customers. These payments and inter-company allocations are in addition to any 12b-1 distribution and/or shareholder service fees or other amounts paid by the Fund under distribution or shareholder servicing plans, or paid by the Fund for shareholder account maintenance, sub-accounting or recordkeeping services provided directly by the financial intermediary providing such services. In exchange for these payments and inter-company allocations, RiverSource Investments and its affiliates may receive preferred access to registered representatives of a financial intermediary (for example, the ability to make presentations in branch offices or at conferences) or preferred access to customers of the financial intermediary (for example, the ability to advertise or directly interact with the financial intermediary's customers in order to sell the Fund). These arrangements are sometimes referred to as "revenue sharing payments." In some cases, these arrangements may create an incentive for a financial intermediary or its representatives to recommend or sell shares of a fund and may create a conflict of interest between a financial intermediary's financial interest and its duties to its customers. Please contact the financial intermediary through which you are purchasing shares of the Fund for details about any payments it may receive in connection with the sale of Fund shares or the provision of services to the Fund. These payments and inter-company allocations are usually calculated based on a percentage of fund sales, and/or as a percentage of fund assets attributable to a particular financial intermediary. These payments may also be negotiated based on other criteria or factors including, but not limited to, the financial intermediary's affiliation with the investment manager, its reputation in the industry, its ability to attract and retain assets, its access to target markets, its customer relationships and the scope and quality of services it provides. The amount of payment or inter-company allocation may vary by financial intermediary and by type of sale (e.g., purchases of different share classes or purchases of the Fund through a qualified plan or through a wrap program), and may be significant. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.14 <Page> From time to time, RiverSource Investments and its affiliates may make other payments, including non-cash compensation, to financial intermediaries or their representatives in the form of gifts of nominal value, occasional meals, tickets, or other entertainment, support for due diligence trips, educational meetings or conference sponsorships, support for recognition programs, and other forms of non-cash compensation permissible under regulations to which these financial intermediaries and their representatives are subject. ADDITIONAL MANAGEMENT INFORMATION MANAGER OF MANAGER EXEMPTION. The Fund operates under an order from the Securities and Exchange Commission that permits RiverSource Investments, subject to the approval of the Board, to appoint a subadviser or change the terms of a subadvisory agreement for the Fund without first obtaining shareholder approval. The order permits the Fund to add or change unaffiliated subadvisers or the fees paid to subadvisers from time to time without the expense and delays associated with obtaining shareholder approval of the change. AFFILIATED FUNDS-OF-FUNDS. RiverSource Investments also serves as investment manager to the RiverSource Portfolio Builder Funds (Portfolio Builder Funds), a group of six funds-of-funds that provide asset-allocation services to shareholders by investing in shares of other RiverSource funds, including the Fund. The Fund may experience relatively large purchases or redemptions from the Portfolio Builder Funds. Although RiverSource Investments seeks to minimize the impact of these transactions by structuring them over a reasonable period of time, the Fund may experience increased expenses as it buys and sells securities to manage transactions for the Portfolio Builder Funds. In addition, because the Portfolio Builder Funds may own a substantial portion of the Fund, a redemption by the Portfolio Builder Funds could cause the Fund's expense ratio to increase as the Fund's fixed costs would be spread over a smaller asset base. RiverSource Investments monitors expense levels and is committed to offering funds that are competitively priced. RiverSource Investments will report to the Fund's Board on the steps it has taken to manage any potential conflicts. FUND HOLDINGS DISCLOSURE. The Fund's Board has adopted policies and procedures that govern the timing and circumstances of disclosure to shareholders and third parties of information regarding the securities owned by the Fund. A description of these policies and procedures is included in the Fund's SAI. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.15 <Page> BUYING AND SELLING SHARES TRANSACTIONS THROUGH UNAFFILIATED FINANCIAL INTERMEDIARIES Where authorized by the distributor, shares of the Fund may be available through certain 401(k) or other qualified plans, banks, broker-dealers or other institutions (financial intermediaries). These financial intermediaries may charge you additional fees for the services they provide and they may have different policies not described in this prospectus. Some policy differences may include different minimum investment amounts, exchange privileges, fund choices and cutoff times for investments. Additionally, recordkeeping, transaction processing and payments of distributions relating to your account may be performed by the financial intermediaries or their representatives through whom shares are held. Since the Fund may not have a record of your transactions, you should always contact the financial intermediary through whom you purchased the Fund to make changes to or give instructions concerning your account or to obtain information about your account. The Fund and the distributor are not responsible for the failure of one of these financial intermediaries to carry out its obligations to its customers. AVAILABILITY AND TRANSFERABILITY OF FUND SHARES. Please consult your investment professional or financial intermediary to determine availability of the Fund. Currently, RiverSource funds may be purchased or sold through affiliated broker-dealers of RiverSource Investments, including Ameriprise Financial Services and Securities America, Inc. (Securities America), and through a limited number of unaffiliated institutions. If you set up an account at another financial intermediary, you will not be able to transfer RiverSource fund holdings to that account unless that institution has obtained a selling agreement with the distributor of the RiverSource funds. If you set up an account with an unaffiliated financial intermediary that does not have, and is unable to obtain, such a selling agreement, you must either maintain your position with Ameriprise Financial Services or Securities America, find another financial intermediary with such a selling agreement, or sell your shares, paying any applicable deferred sales charge. Please be aware that transactions in taxable accounts would generate a taxable event and may result in an increased income tax liability. For more information, please call RiverSource Service Corporation at (888) 791-3380. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.16 <Page> The public offering price for Class A shares of the Fund is the net asset value (NAV) plus a sales charge, and for Class B, C, and Y shares, the NAV. Orders in good form are priced at the NAV next determined after you place your order. Good form or good order means that your instructions have been received in the form required by the distributor. This may include, for example, providing the fund name and account number, the amount of the transaction and all required signatures. For more information, refer to the sections on "Purchasing Shares" and "Exchanging/Selling Shares," or contact your financial advisor or investment professional. If you buy or sell shares through an authorized financial intermediary, consult that firm to determine its procedures for accepting and processing orders. The financial intermediary may charge a fee for its services. VALUING FUND SHARES The NAV is the value of a single share of the Fund. The NAV is determined by dividing the value of the Fund's assets, minus any liabilities, by the number of shares outstanding. The NAV is calculated as of the close of business on the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time, on each day that the NYSE is open. The Fund's securities are valued primarily on the basis of market quotations obtained from outside pricing services approved and monitored under procedures adopted by the Board. Certain short-term securities with maturities of 60 days or less are valued at amortized cost. When reliable market quotations are not readily available, securities are priced at fair value based on procedures adopted by the Board. These procedures are also used when the value of a security held by the Fund is materially affected by events that occur after the close of the primary market on which the security is traded but prior to the time as of which the Fund's NAV is determined. Valuing securities at fair value involves reliance on judgment. The fair value of a security is likely to differ from any available quoted or published price. Foreign investments are valued in U.S. dollars. Some of the Fund's securities may be listed on foreign exchanges that trade on weekends or other days when the Fund does not price its shares. In that event, the NAV of the Fund's shares may change on days when shareholders will not be able to purchase or sell the Fund's shares. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.17 <Page> INVESTMENT OPTIONS 1. CLASS A shares are sold to the public with a sales charge at the time of purchase and an annual distribution and shareholder servicing (12b-1) fee of 0.25%. 2. CLASS B shares are sold to the public with a contingent deferred sales charge (CDSC) and an annual distribution and shareholder servicing (12b-1) fee of 1.00%. 3. CLASS C shares are sold to the public without a sales charge at the time of purchase and with an annual distribution and shareholder servicing (12b-1) fee of 1.00%. Class C shares redeemed within one year after purchase may be subject to a CDSC. 4. CLASS Y shares are sold to qualifying institutional investors without a sales charge or distribution fee, but with a separate shareholder servicing fee of 0.10%. Please see the SAI for information on eligibility requirements to purchase Class Y shares. The distribution and shareholder servicing fees for Class A, Class B and Class C shares are subject to the requirements of Rule 12b-1 under the Investment Company Act of 1940, as amended, and are used to reimburse the distributor for certain expenses it incurs in connection with distributing the Fund's shares and providing services to Fund shareholders. These expenses include payment of distribution and shareholder servicing fees to financial intermediaries that sell shares of the Fund. Financial intermediaries receive shareholder servicing fees equal to 0.25% of the average daily net assets of Class A, Class B and Class C shares sold and held through them. For Class A and Class B shares, the distributor begins to pay these fees immediately after purchase. For Class C shares, the distributor begins to pay these fees one year after purchase. Financial intermediaries also receive distribution fees equal to 0.75% of the average daily net assets of Class C shares sold and held through them, which the distributor begins to pay one year after purchase. For Class B shares, the Fund's distributor retains the 0.75% distribution fee in order to finance the payment of sales commissions to financial intermediaries that sell Class B shares, and to pay for other distribution related expenses. Financial intermediaries may compensate their financial advisors and investment professionals with the shareholder servicing and distribution fees paid to them by the distributor. The shareholder servicing fees for Class Y shares are used to reimburse the distributor for providing services and assistance to shareholders regarding ownership of their shares or their accounts. The Fund also offers an additional class of shares, Class I, exclusively to certain institutional investors. Class I shares are made available through a separate prospectus supplement provided to investors eligible to purchase the shares. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.18 <Page> INVESTMENT OPTIONS SUMMARY The Fund offers different classes of shares. There are differences among the fees and expenses for each class. Not everyone is eligible to buy every class. After determining which classes you are eligible to buy, decide which class best suits your needs. Your financial advisor or investment professional can help you with this decision. The following table shows the key features of each class: <Table> <Caption> CLASS A CLASS B CLASS C CLASS Y - -------------------------------------------------------------------------------------------------------- AVAILABILITY Available to all Available to all Available to all Limited to investors. investors. investors. qualifying institutional investors.

The Fund has also adopted a separate shareholder servicing plan to pay for servicing-related expenses related to Class Y shares. Because these fees are paid out of the Fund's assets on an on-going basis, over time, these fees will increase the cost of your investment and may cost you more than paying other types of distribution (sales) or servicing charges. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.19 <Page> SHOULD YOU PURCHASE CLASS A, CLASS B OR CLASS C SHARES? If your investments in RiverSource funds total $100,000 or more, Class A shares may be the better option because the sales charge is reduced for larger purchases. If you qualify for a waiver of the sales charge, Class A shares will be the best option. If you invest less than $100,000, consider how long you plan to hold your shares. Class B shares have a higher annual distribution fee than Class A shares and a CDSC for six years. Class B shares convert to Class A shares in the ninth year of ownership. Class B shares purchased through reinvested dividends and distributions also will convert to Class A shares in the same proportion as the other Class B shares. Class C shares also have a higher annual distribution fee than Class A shares. Class C shares have no sales charge if you hold the shares for longer than one year. Unlike Class B shares, Class C shares do not convert to Class A. As a result, you will pay a 1% distribution fee for as long as you hold Class C shares. If you choose a deferred sales charge option (Class B or Class C), you should consider the length of time you intend to hold your shares. To help you determine which investment is best for you, consult your financial advisor or investment professional. For more information, see the SAI. PURCHASING SHARES Financial intermediaries are required by law to obtain certain personal information from each person who opens an account in order to verify the identity of the person. As a result, when you open an account you will be asked to provide your name, permanent street address, date of birth, and Social Security or Employer Identification number. You may also be asked for other identifying documents or information. If you do not provide this information, the Fund, or the financial intermediary through which you are investing in the Fund, may not be able to open an account for you. If the Fund or if the financial intermediary through which you are investing in the Fund is unable to verify your identity, your account may be closed, or other steps may be taken, as deemed appropriate. TO PURCHASE SHARES WITH A FINANCIAL INTERMEDIARY OTHER THAN AMERIPRISE FINANCIAL SERVICES, PLEASE CONSULT YOUR FINANCIAL INTERMEDIARY. SEE "TRANSACTIONS THROUGH UNAFFILIATED FINANCIAL INTERMEDIARIES" FOR MORE INFORMATION. THE FOLLOWING SECTION EXPLAINS POLICIES OF THE RIVERSOURCE FUNDS AND HOW YOU CAN PURCHASE FUND SHARES FROM AMERIPRISE FINANCIAL SERVICES. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.20 <Page> If you do not have an existing RiverSource fund account with Ameriprise Financial Services, you will need to establish a brokerage account. Your financial advisor or investment professional will help you fill out and submit an application. Once your account is set up, you can choose among several convenient ways to invest. When you purchase, your order will be priced at the next NAV calculated after your order is accepted by the Fund. If your application does not specify which class of shares you are purchasing, we will assume you are investing in Class A shares. IMPORTANT: When you open an account, you must provide your correct Taxpayer Identification Number (TIN), which is either your Social Security or Employer Identification number. If you do not provide and certify the correct TIN, you could be subject to backup withholding of 28% of taxable distributions and proceeds from certain sales and exchanges. You also could be subject to further penalties, such as: - - a $50 penalty for each failure to supply your correct TIN, - - a civil penalty of $500 if you make a false statement that results in no backup withholding, and - - criminal penalties for falsifying information. You also could be subject to backup withholding, if the IRS notifies us to do so, because you failed to report required interest or dividends on your tax return.

Sales charges vary depending on the amount of your purchase. The distributor receives the sales charge and re-allows a portion of the sales charge to the financial intermediary through which you purchased the shares. The distributor retains the balance of the sales charge. Sales charge* for Class A shares: <Table> <Caption> AS A % OF AS A % OF MAXIMUM RE-ALLOWANCE TOTAL MARKET VALUE PURCHASE PRICE** NET AMOUNT INVESTED AS A % OF PURCHASE PRICE Up to $49,999 5.75% 6.10% 5.00% $50,000-$99,999 4.75 4.99 4.00 $100,000-$249,999 3.50 3.63 3.00 $250,000-$499,999 2.50 2.56 2.15 $500,000-$999,999 2.00 2.04 1.75 $1,000,000 or more*** 0.00 0.00 0.00 </Table> * Because of rounding in the calculation of the offering price, the portion of the sales charge retained by the distributor may vary and the actual sales charge you pay may be more or less than the sales charge calculated using these percentages. ** Offering price includes the sales charge. *** Although there is no sales charge for purchases with a total market value over $1,000,000, and therefore no re-allowance, the distributor may pay a sales commission to a financial intermediary making a sale with a total market value of $1,000,000 to $3,000,000, a sales commission up to 1.00%; $3,000,000 to $10,000,000, a sales commission up to 0.50%; and $10,000,000 or more, a sales commission up to 0.25%. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.23 <Page> RIGHTS OF ACCUMULATION YOU MAY BE ABLE TO REDUCE THE SALES CHARGE ON CLASS A SHARES, BASED ON THE COMBINED MARKET VALUE OF YOUR ACCOUNTS. The current market values of the following investments are eligible to be added together for purposes of determining the sales charge on your purchase: - - Your current investment in this Fund, and - - Previous investments you and members of your primary household group have made in Class A, Class B or Class C shares in this and other RiverSource funds, provided your investment was subject to a sales charge. - Your primary household group consists of you, your spouse or domestic partner, and your unmarried children under age 21 sharing a mailing address. For purposes of this policy a domestic partner is an individual who shares your primary residence and with whom you own joint property. If you or any member of your primary household group elects to separate from the primary household group (for example, by asking that account statements be sent to separate addresses), your assets will no longer be combined for purposes of reducing your sales charge. The following accounts are eligible to be included in determining the sales charge on your purchase: - - Individual or joint accounts held outside of a brokerage account; - - Individual or joint accounts held through a brokerage account; - - Roth and traditional IRAs, SEPs, SIMPLEs and TSCAs, provided they are invested in Class A, Class B or Class C shares that are subject to a sales charge; - - UGMA/UTMA accounts for which you, your spouse, or your domestic partner is parent or guardian of the minor child; - - Revocable trust accounts for which you or a member of your primary household group, individually, is the beneficiary; - - Accounts held in the name of your, your spouse's, or your domestic partner's sole proprietorship or single owner limited liability company or S corporation; and - - Qualified retirement plan assets, provided that you are the sole owner of the business sponsoring the plan, are the sole participant (other than a spouse) in the plan, and have no intention of adding participants to the plan. The following accounts are NOT eligible to be included in determining the sales charge on your purchase: - - Accounts of pension and retirement plans with multiple participants, such as 401(k) plans (which are combined to reduce the sales charge for the entire pension or retirement plan and therefore are not used to reduce the sales charge for your individual accounts); RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.24 <Page> - - Investments in Class A shares where the sales charge is waived, for example, purchases through wrap accounts, including Ameriprise Strategic Portfolio Service ADVANTAGE (SPS); - - Investments in Class D, Class E, or Class Y shares; - - Investments in 529 plans, donor advised funds, variable annuities, variable life insurance products, wrap accounts or managed separate accounts; and - - Charitable and irrevocable trust accounts. If you purchase RiverSource fund shares through different channels or different financial intermediaries, and you want to include those assets toward a reduced sales charge, you must inform Ameriprise Financial Services, your financial advisor or investment professional in writing about the other accounts when placing your purchase order. When placing your purchase order, you must provide your most recent account statement and contact information regarding the other accounts. A financial intermediary other than Ameriprise Financial Services may require additional information. UNLESS YOU PROVIDE AMERIPRISE FINANCIAL SERVICES, YOUR FINANCIAL ADVISOR OR YOUR INVESTMENT PROFESSIONAL IN WRITING WITH INFORMATION ABOUT ALL OF THE ACCOUNTS THAT MAY COUNT TOWARD A SALES CHARGE REDUCTION, THERE CAN BE NO ASSURANCE THAT YOU WILL RECEIVE ALL OF THE REDUCTIONS FOR WHICH YOU MAY BE ELIGIBLE. For more information on rights of accumulation, please see the SAI. LETTER OF INTENT (LOI) Generally, if you intend to invest $50,000 or more over a period of 13 months, you may be able to reduce the front-end sales charges for investments in Class A shares by completing and filing a LOI form. The LOI becomes effective only after the form is processed in good order by the distributor. An LOI can be backdated up to a maximum of 90 days. If the LOI is backdated, you may include prior investments in Class A shares that were charged a front-end sales load toward the LOI commitment amount. If the LOI is backdated, the 13 month period begins on the date of the earliest purchase included in the LOI. HOLDINGS MORE THAN 90 DAYS OLD. Purchases made more than 90 days before your LOI is processed by the distributor will not be counted towards the commitment amount of the LOI and cannot be used as the starting point for the LOI. While these purchases cannot be included in an LOI, they may help you obtain a reduced sales charge on future purchases as described in "Rights of Accumulation." RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.25 <Page> NOTIFICATION OBLIGATION. If purchasing shares in a brokerage account or through a financial intermediary, you must request the reduced sales charge when you buy shares. If you do not complete and file the LOI form, or do not request the reduced sales charge at the time of purchase, you will not be eligible for the reduced sales charge. For more details on LOIs, please contact your financial advisor, investment professional or see the SAI. WAIVERS OF THE SALES CHARGE FOR CLASS A SHARES Sales charges do not apply to: - - current or retired Board members, officers or employees of the Fund or Ameriprise Financial or its subsidiaries, their spouses or domestic partners, children and parents. - - current or retired Ameriprise Financial Services financial advisors, employees of financial advisors, their spouses or domestic partners, children and parents. - - portfolio managers employed by subadvisers of the RiverSource funds, including their spouses or domestic partners, children and parents. - - registered representatives and other employees of financial intermediaries having a sub-distribution agreement with the distributor, including their spouses, domestic partners, children and parents. - - qualified employee benefit plans offering participants daily access to RiverSource funds.

Participants in certain qualified plans where the initial sales charge is waived may be subject to a deferred sales charge of up to 4%. - - shareholders who have at least $1 million in RiverSource funds. If the investment is sold within one year after purchase, a CDSC of 1% may be charged. - - direct rollovers from Ameriprise Retirement Services, provided that the rollover involves a transfer of Class Y shares in this Fund to Class A shares in this Fund. - - purchases made: - with dividend or capital gain distributions from this Fund or from the same class of another RiverSource fund, - through or under a wrap fee product or other investment product sponsored by the distributor or another authorized broker-dealer, investment advisor, bank or investment professional, - within a segregated separate account offered by Nationwide Life Insurance Company or Nationwide Life and Annuity Insurance Company, RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.26 <Page> - through American Express Personal Trust Services' Asset-Based pricing alternative, provided by American Express Bank, FSB. - - shareholders whose original purchase was in a Strategist fund merged into a RiverSource fund in 2000. Policies related to reducing or waiving the sales charge may be modified or withdrawn at any time. UNLESS YOU PROVIDE AMERIPRISE FINANCIAL SERVICES, YOUR FINANCIAL ADVISOR OR INVESTMENT PROFESSIONAL WITH INFORMATION IN WRITING ABOUT ALL OF THE FACTORS THAT MAY COUNT TOWARD A WAIVER OF THE SALES CHARGE, THERE CAN BE NO ASSURANCE THAT YOU WILL RECEIVE ALL OF THE WAIVERS FOR WHICH YOU MAY BE ELIGIBLE. You also may view this information about sales charges and breakpoints free of charge on the Fund's website. Go to www.riversource.com/investments and click on the hyperlink "Sales Charge Discount Information." CLASS B AND CLASS C -- CONTINGENT DEFERRED SALES CHARGE (CDSC) ALTERNATIVE FOR CLASS B, the CDSC is based on the sale amount and the number of years -- including the year of purchase -- between purchase and sale. The following table shows how CDSC percentages on sales decline: <Table> <Caption> IF THE SALE IS MADE DURING THE: THE CDSC PERCENTAGE RATE IS:* First year 5% Second year 4% Third year 4% Fourth year 3% Fifth year 2% Sixth year 1% Seventh year 0% </Table> * Because of rounding in the calculation, the portion of the CDSC retained by the distributor may vary and the actual CDSC you pay may be more or less than the CDSC calculated using these percentages. Although there is no front-end sales charge when you buy Class B shares, the distributor pays a sales commission of 4% to financial intermediaries that sell Class B shares. A portion of this commission may, in turn, be paid to your financial advisor. The distributor receives any CDSC imposed when you sell your Class B shares. Purchases made prior to May 21, 2005 age on a calendar year basis. Purchases made beginning May 21, 2005 age on a daily basis. For example, a purchase made on Nov. 12, 2004 will complete its first year on Dec. 31, 2004 under calendar year aging. However, a purchase made on Nov. 12, 2005 will complete its first year on Nov. 11, 2006 under daily aging. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.27 <Page> For Class B shares purchased prior to May 21, 2005, those shares will convert to Class A shares in the ninth calendar year of ownership. For Class B shares purchased beginning May 21, 2005, those shares will convert to Class A shares one month after the completion of the eighth year of ownership. FOR CLASS C, a 1% CDSC may be charged if you sell your shares within one year after purchase. Although there is no front-end sales charge when you buy Class C shares, the distributor pays a sales commission of 1% to financial intermediaries that sell Class C shares. A portion of this commission may, in turn, be paid to your financial advisor. The distributor receives any CDSC imposed when you sell your Class C shares. For both Class B and Class C, if the amount you sell causes the value of your investment to fall below the cost of the shares you have purchased, the CDSC will be based on the lower of the cost of those shares purchased or market value. Because the CDSC is imposed only on sales that reduce your total purchase payments, you do not have to pay a CDSC on any amount that represents appreciation in the value of your shares, income earned by your shares, or capital gains. In addition, the CDSC on your sale, if any, will be based on your oldest purchase payment. The CDSC on the next amount sold will be based on the next oldest purchase payment. EXAMPLE Assume you had invested $10,000 in Class B shares and that your investment had appreciated in value to $12,000 after 3 1/2 years, including reinvested dividends and capital gain distributions. You could sell up to $2,000 worth of shares without paying a CDSC ($12,000 current value less $10,000 purchase amount). If you sold $2,500 worth of shares, the CDSC would apply to the $500 representing part of your original purchase price. The CDSC rate would be 3% because the sale was made during the fourth year after the purchase. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.28 <Page> WAIVERS OF THE CDSC FOR CLASS B SHARES The CDSC will be waived on sales of shares: - - in the event of the shareholder's death, - - held in trust for an employee benefit plan, or - - held in IRAs or certain qualified plans if Ameriprise Trust Company is the custodian, such as Keogh plans, tax-sheltered custodial accounts or corporate pension plans, provided that the shareholder is: - at least 59 1/2 years old AND - taking a retirement distribution (if the sale is part of a transfer to an IRA or qualified plan, or a custodian-to-custodian transfer, the CDSC will not be waived) OR - selling under an approved substantially equal periodic payment arrangement. WAIVERS OF THE CDSC FOR CLASS C SHARES The CDSC will be waived on sales of shares in the event of the shareholder's death. EXCHANGING/SELLING SHARES TO SELL OR EXCHANGE SHARES HELD WITH FINANCIAL INTERMEDIARIES OTHER THAN AMERIPRISE FINANCIAL SERVICES, PLEASE CONSULT YOUR FINANCIAL INTERMEDIARY. SEE "TRANSACTIONS THROUGH UNAFFILIATED FINANCIAL INTERMEDIARIES" FOR MORE INFORMATION. THE FOLLOWING SECTION EXPLAINS POLICIES OF THE RIVERSOURCE FUNDS ON HOW YOU CAN EXCHANGE OR SELL SHARES HELD WITH AMERIPRISE FINANCIAL SERVICES. EXCHANGES You may exchange your Fund shares at no charge for shares of the same class of any other publicly offered RiverSource fund. Exchanges into RiverSource Tax-Exempt Money Market Fund may only be made from Class A shares. For complete information on the other fund, including fees and expenses, read that fund's prospectus carefully. Your exchange will be priced at the next NAV calculated after your transaction request is received in good order. MARKET TIMING IS FREQUENT OR SHORT-TERM TRADING BY CERTAIN SHAREHOLDERS INTENDED TO PROFIT AT THE EXPENSE OF OTHER SHAREHOLDERS BY SELLING SHARES OF A FUND SHORTLY AFTER PURCHASE. MARKET TIMING MAY ADVERSELY IMPACT A FUND'S PERFORMANCE BY PREVENTING THE INVESTMENT MANAGER FROM FULLY INVESTING THE ASSETS OF THE FUND, DILUTING THE VALUE OF SHARES HELD BY LONG-TERM SHAREHOLDERS, OR INCREASING THE FUND'S TRANSACTION COSTS. SEE "VALUING FUND SHARES" FOR A DISCUSSION OF THE FUND'S POLICY ON FAIR VALUE PRICING, WHICH IS INTENDED, IN PART, TO REDUCE THE FREQUENCY AND EFFECT OF MARKET TIMING. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.29 <Page> THE FUND'S BOARD HAS ADOPTED A POLICY THAT IS DESIGNED TO DETECT AND DETER MARKET TIMING. THE FUND SEEKS TO ENFORCE THIS POLICY AS FOLLOWS: - - The Fund tries to distinguish market timing from trading that it believes is not harmful, such as periodic rebalancing for purposes of asset allocation or dollar cost averaging. Under the Fund's procedures, there is no set number of transactions in the Fund that constitutes market timing. Even one purchase and subsequent sale by related accounts may be market timing. Generally, the Fund seeks to restrict the exchange privilege of an investor who makes more than three exchanges into or out of the Fund in any 90-day period. Accounts held by a retirement plan or an institution for the benefit of its participants or clients, which typically engage in daily transactions, are not subject to this limit. The Fund seeks the assistance of financial intermediaries in applying similar restrictions on the sub-accounts of their participants or clients. - - If an investor's trading activity is determined to be market timing or otherwise harmful to existing shareholders, the Fund reserves the right to modify or discontinue the investor's exchange privilege or reject the investor's purchases or exchanges, including purchases or exchanges accepted by a financial intermediary. The Fund may treat accounts it believes to be under common control as a single account for these purposes, although it may not be able to identify all such accounts. - - Although the Fund does not knowingly permit market timing, it cannot guarantee that it will be able to identify and restrict all short-term trading activity. The Fund receives purchase and sale orders through financial intermediaries where market timing activity may not always be successfully detected. Other exchange policies: - - Exchanges must be made into the same class of shares of the new fund. - - If your exchange creates a new account, it must satisfy the minimum investment amount for new purchases. - - Once we receive your exchange request, you cannot cancel it. - - Shares of the new fund may not be used on the same day for another exchange. - - If your shares are pledged as collateral, the exchange will be delayed until written approval is received from the secured party. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.30 <Page> SELLING SHARES You may sell your shares at any time. The payment will be mailed within seven days after your request is received in good order. When you sell shares, the amount you receive may be more or less than the amount you invested. Your sale price will be the next NAV calculated after your request is received in good order, minus any applicable CDSC. REPURCHASES. You can change your mind after requesting a sale and use all or part of the proceeds to purchase new shares in the same account from which you sold. If you reinvest in Class A, you will purchase the new shares at NAV rather than the offering price on the date of a new purchase. If you reinvest in Class B or Class C, any CDSC you paid on the amount you are reinvesting also will be reinvested. To take advantage of this waiver, you must send a written request within 90 days of the date your sale request was processed and include your account number. This privilege may be limited or withdrawn at any time and use of this option may have tax consequences. The Fund reserves the right to redeem in kind. For more details and a description of other sales policies, please see the SAI. If you decide to sell your shares within 30 days of a telephoned-in address change, a written request is required. IMPORTANT: Payments sent by a bank authorization, check or money order that are not guaranteed may take up to ten days to clear. This may cause your scheduled arrangement or unscheduled request to fail to process if the requested amount includes unguaranteed funds.

ELECTRONIC TRANSACTIONS The ability to initiate transactions via the internet may be unavailable or delayed at certain times (for example, during periods of unusual market activity). The Fund and the distributor are not responsible for any losses associated with unexecuted transactions. In addition, the Fund and the distributor are not responsible for any losses resulting from unauthorized transactions if reasonable security measures are followed to validate the investor's identity. The Fund may modify or discontinue electronic privileges at any time for any shareholder without prior notice as deemed necessary and in the best interests of the Fund. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.33 <Page> DISTRIBUTIONS AND TAXES As a shareholder you are entitled to your share of the Fund's net income and net gains. The Fund distributes dividends and capital gains to qualify as a regulated investment company and to avoid paying corporate income and excise taxes. DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS The Fund's net investment income is distributed to you as DIVIDENDS. Dividends may be composed of qualifying dividend income, which is eligible for preferential tax rates under current tax law, as well as other ordinary dividend income, which may include non-qualifying dividends, interest income and short-term capital gains. Capital gains are realized when a security is sold for a higher price than was paid for it. Each realized capital gain or loss is long-term or short-term depending on the length of time the Fund held the security. Realized capital gains and losses offset each other. The Fund offsets any net realized capital gains by any available capital loss carryovers. Net short-term capital gains are included in net investment income. Net realized long-term capital gains, if any, are distributed by the end of the calendar year as CAPITAL GAIN DISTRIBUTIONS. REINVESTMENTS Dividends and capital gain distributions are automatically reinvested in additional shares in the same class of the Fund, unless: - - you request distributions in cash, or - - you direct the Fund to invest your distributions in the same class of any publicly offered RiverSource fund for which you have previously opened an account. We reinvest the distributions for you at the next calculated NAV after the distribution is paid. If you choose cash distributions, you will receive cash only for distributions declared after your request has been processed. RIVERSOURCE STOCK FUND -- PROXY STATEMENT D.34 <Page> TAXES Distributions are subject to federal income tax and may be subject to state and local taxes in the year they are declared. You must report distributions on your tax returns, even if they are reinvested in additional shares. If you buy shares shortly before the record date of a distribution, you may pay taxes on money earned by the Fund before you were a shareholder. You will pay the full pre-distribution price for the shares, then receive a portion of your investment back as a distribution, which may be taxable. For tax purposes, an exchange is considered a sale and purchase, and may result in a gain or loss. A sale is a taxable transaction. If you sell shares for less than their cost, the difference is a capital loss. If you sell shares for more than their cost, the difference is a capital gain. Your gain may be short term (for shares held for one year or less) or long term (for shares held for more than one year). You may not create a tax loss, based on paying a sales charge, by exchanging shares within 91 days of purchase. If you buy Class A shares and within 91 days exchange into another fund, you may not include the sales charge in your calculation of tax gain or loss on the sale of the first fund you purchased. The sales charge may be included in the calculation of your tax gain or loss on a subsequent sale of the second fund you purchased. For more information, see the SAI. Selling shares held in an IRA or qualified retirement account may subject you to federal taxes, penalties and reporting requirements. Please consult your tax advisor. IMPORTANT: This information is a brief and selective summary of some of the tax rules that apply to this Fund. Because tax matters are highly individual and complex, you should consult a qualified tax advisor.

The Committee may delegate any portion of its authority, including the authority to grant pre-approvals of audit and permitted non-audit services to one or more members. Any decisions of the member to grant pre-approvals shall be presented to the Committee at its next regularly scheduled meeting. ROLE AND RESPONSIBILITIES The function of the Committee is oversight; it is American Express Financial Corporation's responsibility to maintain appropriate systems for accounting and internal control over financial reporting, and the Auditor's responsibility to plan and carry out a proper audit. Specifically, American Express Financial Corporation is responsible for: (1) the preparation, presentation and integrity of the Fund's financial statements; (2) the maintenance of appropriate accounting and financial reporting principles and policies; and (3) the maintenance of internal control over financial reporting and other procedures designed to assure compliance with accounting standards and related laws and regulations. The Auditor is responsible for planning and carrying out an audit consistent with applicable legal and professional standards and the terms of their engagement letter. Nothing in the Charter shall be construed to reduce the responsibilities or liabilities of the Fund's service providers, including the Auditor. Although the Committee is expected to take a detached and questioning approach to the matters that come before it, the review of a Fund's financial statements by the Committee is not an audit, nor does the Committee's review substitute for the responsibilities of American Express Financial Corporation's for preparing, or the Auditor for auditing, the financial statements. Members of the Committee are not employees of the Fund and, in serving on this Committee, are not, and do not hold themselves out to be, acting as accountants or auditors. As such, it is not the duty or responsibility of the Committee or its members to conduct "field work" or other types of auditing or accounting reviews or procedures. RIVERSOURCE STOCK FUND -- PROXY STATEMENT F.5 <Page> In discharging their duties, the members of the Committee are entitled to rely on information, opinions, reports, or statements, including financial statements and other financial data, if prepared or presented by: (1) one or more officers of the Fund whom the director reasonably believes to be reliable and competent in the matters presented; (2) legal counsel, public accountants, or other persons as to matters the director reasonably believes are within the person's professional or expert competence; or (3) a Board committee of which the director is not a member. OPERATIONS The Board shall adopt and approve this Charter and may amend it on the Board's own motion. The Committee shall review this Charter at least annually and recommend to the full Board any changes the Committee deems appropriate. The Committee may select one of its members to be the chair and may select a vice chair. A majority of the members of the Committee shall constitute a quorum for the transaction of business at any meeting of the Committee. The action of a majority of the members of the Audit Committee present at a meeting at which a quorum is present shall be the action of the Committee. The Committee shall meet on a regular basis and at least four times annually and is empowered to hold special meetings as circumstances require. The Chairperson or a majority of the members shall be authorized to call a meeting of the Committee or meetings may be fixed in advance by the Committee. The agenda shall be prepared under the direction and control of the Chairperson. The Committee shall ordinarily meet in person; however, members may attend telephonically, and the Committee may act by written consent, to the extent permitted by law and by the Fund's bylaws. The Committee shall have the authority to meet privately and to admit non-members individually. The Committee may also request to meet with internal legal counsel and compliance personnel of American Express Financial Corporation and with entities that provide significant accounting or administrative services to the Fund to discuss matters relating to the Fund's accounting and compliance as well as other Fund-related matters. The Committee shall prepare and retain minutes of its meetings and appropriate documentation of decisions made outside of meetings by delegated authority. The Committee shall evaluate its performance at least annually.

WE ENCOURAGE YOU TO READ THE FULL TEXT OF THE ENCLOSED PROXY STATEMENT. Q: WHAT CHANGES HAVE RECENTLY TAKEN PLACE? On Sept. 30, the Fund's investment manager, Ameriprise Financial, Inc. ("Ameriprise Financial") (formerly American Express Financial Corporation) was spun off from its parent company, American Express Company. The investment management functions were then moved to RiverSource Investments, LLC ("RiverSource Investments"), a wholly-owned subsidiary of Ameriprise Financial. The Board of Directors ("Board") changed the name of each fund and the funds are now listed in newspapers under RiverSource. Q: WHY AM I BEING ASKED TO VOTE? Mutual funds are required to get shareholders' approval for certain contracts and certain kinds of changes, like the ones included in this proxy statement. Q: IS MY VOTE IMPORTANT? Absolutely! While the Board of each RiverSource Fund has reviewed these changes and recommends you approve them, you have the right to voice your opinion. Until the Fund is sure that a quorum has been reached (50% of existing shares), it will continue to contact shareholders asking them to vote. These efforts cost money -- so please, vote immediately. Q: WHAT AM I BEING ASKED TO VOTE ON? Shareholders are being asked to vote on: - - The merger ("Reorganization") of RiverSource Stock Fund and RiverSource Disciplined Equity Fund. - - Election of Board members. <Page> - - An amendment to the Fund's Articles of Incorporation to permit the Board to establish the minimum account value and to change the name of the corporation to "RiverSource" consistent with the name of the fund. - - An Investment Management Services Agreement ("IMS Agreement") with RiverSource Investments. We encourage you to read the full text of the proxy statement to obtain a more detailed understanding of the issues. Q: IF APPROVED, WHEN WILL THE REORGANIZATION HAPPEN? If shareholders approve the Reorganization, it will take place shortly after the shareholder meeting. In the interim, however, it will be important for the Fund to have a properly elected Board and an IMS Agreement that has been approved by shareholders. Q: WHAT DO BOARD MEMBERS DO? Board members represent the interests of the shareholders and oversee the management of the Fund. Q: WHAT CHANGES ARE PROPOSED TO THE INVESTMENT MANAGEMENT SERVICES AGREEMENT? While the spin off of Ameriprise Financial and transfer of the IMS Agreement to RiverSource Investments did not cause a termination of the IMS Agreement, the Board determined that it would be prudent to give shareholders an opportunity to vote on the IMS Agreement. The IMS Agreement also clarifies the circumstances under which the Board may change an index for purposes of calculating a performance incentive adjustment. Q: HOW DOES THE BOARD RECOMMEND THAT I VOTE? After careful consideration, the Board recommends that you vote FOR each proposal. Q: HOW DO I VOTE? You can vote in one of four ways: - - By mail with the enclosed proxy card - - By telephone - - By web site - - In person at the meeting Please refer to the enclosed voting instruction card for the telephone number and internet address. Q: WHOM SHOULD I CALL IF I HAVE QUESTIONS? If you have questions about any of the proposals described in the proxy statement or about voting procedures, please call your financial advisor or call client services toll free at (877) 256-6085.

Cap Equity Fund RiverSource Large Cap Equity Fund (Buying Fund) RiverSource New Dimensions Fund (Selling Fund) Notes to Pro Forma Financial Statements (Unaudited as to July 31, 2005) 1. BASIS OF COMBINATION The unaudited pro forma combining statement of assets and liabilities and the statement of operations reflect the accounts of the two funds at and for the 12-month period ending July 31, 2005. These statements have been derived from financial statements prepared for the RiverSource Large Cap Equity Fund and RiverSource New Dimensions Fund as of July 31, 2005. Each Fund is registered under the Investment Company Act of 1940 (as amended) as a diversified, open-end management investment company. The primary investments of each Fund are as follows: RiverSource Large Cap Equity Fund invests primarily in equity securities with a market capitalization greater than $5 billion at the time of purchase. RiverSource New Dimensions Fund invests all of its assets in Growth Trends Portfolio, a series of Growth Trust, an open-end investment company that has the same objectives as the Fund. The Portfolio invests primarily in common stocks showing potential for significant growth and operating in areas where economic or technological changes are occurring. The pro forma statements give effect to the proposed transfer of the assets and liabilities of RiverSource New Dimensions Fund in exchange for Class A, B, C, I and Y shares of RiverSource Large Cap Equity Fund under U.S. generally accepted accounting principles. The pro forma statements also reflect changes needed regarding the change in structure of RiverSource New Dimensions Fund. Finally, the pro forma statements reflect estimates for the combined RiverSource Large Cap Equity Fund based on the increased asset level of the merger and associated economies of scale, adjusted to reflect current fees. The pro forma combining statements should be read in conjunction with the historical financial statements of the funds incorporated by reference in the Statement of Additional Information. The pro forma statement of operations give effect to the proposed transaction on the historical operations of the accounting survivor, RiverSource Large Cap Equity Fund, as if the transaction had occurred at the beginning of the year presented. 2. PRO FORMA ADJUSTMENTS (a) To reflect adjustments needed regarding the change in structure of RiverSource New Dimensions Fund from a feeder fund presentation into a reporting format comparable with the accounting survivor. (b) To adjust for the termination of the agreement that RiverSource Investments and its affiliates would waive certain fees and absorb certain expenses. (c) To reflect the increase in investment management services fee due to the Reorganization. The Performance Incentive Adjustment (PIA) for RiverSource New Dimensions Fund was removed and a new PIA adjustment was calculated based on the RiverSource New Dimensions Fund average net assets as of July 31, 2005 and the RiverSource Large Cap Equity Fund PIA rate. The adjustment also includes the impact of a special management fee waiver that will be in effect until August 2006 on the merged fund. This special management fee waiver is estimated to reduce the management fee ratio by approximately 0.02%. (d) To reflect the net increase in administrative services fees due to the Reorganization and the revised administrative services agreement. (e) To reflect the decrease in custodian fees due to the Reorganization. (f) To adjust for the change in the compensation of board members due to the Reorganization. (g) To reflect the reduction in audit fees due to the Reorganization. (h) To adjust for closed account fees for each RiverSource New Dimensions Fund account that will be closed on the system as a result of this merger. (i) To reflect the anticipated reduction in the transfer agent fees due to the RiverSource Large Cap Equity Fund and RiverSource New Dimensions Fund accounts that will be combined as a result of the merger. 5 -- AXP Fixed Income Series, Inc. -- RiverSource Large Cap Equity Fund 3.

S-6389-20 A (12/05) PART C. OTHER INFORMATION Item 15. Indemnification The Articles of Incorporation of the registrant provide that the Fund shall indemnify any person who was or is a party or is threatened to be made a party, by reason of the fact that she or he is or was a director, officer, employee or agent of the Fund, or is or was serving at the request of the Fund as a director, officer, employee or agent of another company, partnership, joint venture, trust or other enterprise, to any threatened, pending or completed action, suit or proceeding, wherever brought, and the Fund may purchase liability insurance and advance legal expenses, all to the fullest extent permitted by the laws of the State of Minnesota, as now existing or hereafter amended. The By-laws of the registrant provide that present or former directors or officers of the Fund made or threatened to be made a party to or involved (including as a witness) in an actual or threatened action, suit or proceeding shall be indemnified by the Fund to the full extent authorized by the Minnesota Business Corporation Act, all as more fully set forth in the By-laws filed as an exhibit to this registration statement. Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. Any indemnification hereunder shall not be exclusive of any other rights of indemnification to which the directors, officers, employees or agents might otherwise be entitled. No indemnification shall be made in violation of the Investment Company Act of 1940. Item 16.
