Investment Objective
The Fund's investment objective is long-term growth. The Fund seeks to increase shareholder capital over the long term.

Investment Strategy
The Fund invests principally in equity securities of companies with market capitalizations of up to $3 billion that RS Investments believes are undervalued. In evaluating investments for the Fund, RS Investments employs a return on capital analysis, combining balance sheet and cash flow analysis. The Fund typically invests most of its assets in securities of U.S. companies, but may also invest any portion of its assets in foreign securities. The Fund is a non-diversified mutual fund.

Since its inception, the Fund frequently has held a substantial portion of its assets, at times equaling or exceeding 25%, in cash and cash equivalents. The Fund may, but will not necessarily, do so in the future.

Investment Process
In evaluating investments for the Fund, RS Investments employs a value methodology, combining balance sheet and cash flow analysis. We may perform a number of analyses in evaluating a potential investment, including, for example:
  •   performing fundamental research focusing on business analysis;
  •   observing how management allocates capital;
  •   striving to understand the unit economics of the business of the company;
  •   studying the cash flow rate of return on capital employed;
  •   discerning the sources and uses of cash;
  •   considering how management is compensated;
  •   asking how the stock market is pricing the entire company.

Sell Discipline
Although RS Investments may consider the factors described above in purchasing or selling investments in the Fund, RS Investments may purchase, sell, or continue to hold an investment for the Fund whenever it believes doing so may benefit the Fund, or on the basis of any of the factors described above or any other factors it may in its discretion consider.

Risk Factors
As with all mutual funds, the value of an investment in the Fund could decline, so you could lose money. Investments in companies in natural resources industries may involve risks including changes in commodities prices, changes in demand for various natural resources, changes in energy prices, and international political and economic developments.Investing in small- and mid-size companies can involve risks such as having less publicly available information, higher volatility, and less liquidity than in the case of larger companies. Investing in a more limited number of issuers and sectors can be subject to greater market fluctuation. Overweighting investments in certain sectors or industries increases the risk of loss due to general declines in the prices of stocks in those sectors or industries. Foreign securities are subject to political, regulatory, economic, and exchange-rate risks not present in domestic investments. The value of a debt security is affected by changes in interest rates and is subject to any credit risk of the issuer or guarantor of the security.

Performance Update (Class A)
Average Annual Total Returns For Periods ended 6/30/08

Performance quoted represents past performance and does not guarantee future results. Investment return and principal value will fluctuate, so shares, when redeemed, may be worth more or less than their original cost. Please keep in mind that any high double-digit returns are highly unusual and cannot be sustained. As of the most current prospectus, the Fund's total gross annual operating expense ratio for the Class A shares is 1.51%. Class A performance quoted "with maximum sales charge" reflects the current maximum sales charge of 4.75%. Please read the prospectus carefully for more information on sales charges as they do not apply in all cases and if applied are reduced for larger purchases. Any sales charges are in addition to the Funds’ fees and expenses as detailed in the Funds’ most current prospectus. Fees and expenses are factored into the net asset value of your shares and any performance numbers we release. Total return figures reflect an expense limitation in effect during the periods shown; without such limitation, the performance shown would have been lower. Performance results assume the reinvestment of dividends and capital gains. The return figures shown do not reflect the deduction of taxes that a shareholder may pay on Fund distributions or the redemption of Fund shares. Current and month-end performance information, which may be lower or higher than that cited, is available by contacting RS Investments at 800-766-3863 and is frequently updated on our Web site: www.RSinvestments.com.

* The Russell 2000^® Value Index is an unmanaged market-capitalization-weighted index that measures the performance of those companies in the Russell 2000^® Index with lower price-to-book ratios and lower forecasted growth values. (The Russell 2000^® Index measures the performance of the 2,000 smallest companies in the Russell 3000^® Index, which consists of the 3,000 largest U.S. companies based on total market capitalization.) Index results assume the reinvestment of dividends paid on the stocks constituting the index. You may not invest in the index, and, unlike the Fund, the index does not incur fees and expenses.
