This expense limitation will continue through April 30, 2014 and cannot be terminated by RS Investments prior to that date without the action or consent of the Fund's Board of Trustees.
Example
This Example is intended to help you compare the cost of investing in the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. This Example also assumes that your investment earns a 5% return each year and that the Fund’s operating expenses remain the same as shown above. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 51% of the average value of its portfolio.
Investments, Risks, and Performance
Principal Investment Strategies
The Fund normally invests at least 80% of its net assets in companies considered by the Fund’s investment team (at the time of purchase) to be large-capitalization companies. The Fund’s investment team considers a company to be large-capitalization if its market capitalization is between $5 billion and the market capitalization of the largest company included in the Russell 1000® Index on the last day of the most recent quarter (currently, approximately $415.7 billion, based on the size of the largest company in the Index on March 31, 2013). The Fund’s investment team currently expects that the Fund typically will hold between 35 and 45 securities positions.

In evaluating investments for the Fund, the Fund’s investment team conducts fundamental research to identify companies with improving returns on invested capital. The investment team’s research efforts seek to identify the primary economic and value drivers for each company. Research focuses on a company’s capital deployment strategy, including decisions about capital expenditures, acquisitions, cost-saving initiatives, and share repurchase/dividend plans, as the Fund’s investment team seeks to understand how returns on invested capital may improve over time. Valuation is considered an important part of the process. The investment team seeks to invest in companies based on the investment team’s assessment of risk (the possibility of permanent capital impairment) and its assessment of reward (the future value of the enterprise).

The Fund may at times, but will not necessarily, hold a substantial portion of its assets in cash and cash equivalents.

The Fund will typically invest principally in equity securities. The Fund may at times, but will not necessarily, invest a substantial portion of its assets in securities of companies that the investment team considers to be principally engaged in natural resources industries. Companies in natural resources industries include companies that the Fund’s investment team considers to be principally engaged in the discovery, development, production, or distribution of natural resources; the development of technologies for the production or efficient use of natural resources; or the furnishing of related supplies or services. 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.
Principal Risks
You may lose money by investing in the Fund. The Fund may not achieve its investment objective. The principal risks of investing in the Fund, which could adversely affect its net asset value and total return, are as follows.

Equity Securities Risk
The value of a company’s stock may decline in response to factors affecting that particular company or stock markets generally.

Investment Style Risk
A mutual fund investing principally in value style stocks may at times underperform other mutual funds that invest more broadly or that have different investment styles.

Overweighting Risk
Overweighting investments in an industry or group of industries relative to the Fund’s primary benchmark increases the risk that the Fund will underperform its primary benchmark because a general decline in the prices of stocks in that industry or group of industries will affect the Fund to a greater extent than its primary benchmark.

Underweighting Risk
If the Fund underweights its investment in an industry or group of industries relative to the Fund’s primary benchmark, the Fund will participate in any general increase in the value of companies in that industry or group of industries to a lesser extent than the Fund’s primary benchmark.

Foreign Securities Risk
Foreign securities are subject to political, regulatory, and economic risks not present in domestic investments. In addition, when the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent that investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund.

Cash Position Risk
To the extent that the Fund holds assets in cash and cash equivalents and not in the investments previously described, the ability of the Fund to meet its objective may be limited.

Liquidity Risk
Lack of a ready market or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price. In addition, the Fund, by itself or together with other accounts managed by RS Investments, may hold a position in a security that is large relative to the typical trading volume for that security, which can make it difficult for the Fund to dispose of the position at an advantageous time or price.

Natural Resources Investment Risk
Investment in companies in natural resources industries can be significantly affected by (often rapid) changes in supply of, or demand for, various natural resources. They may also be affected by changes in energy prices, international political and economic developments, environmental incidents, energy conservation, the success of exploration projects, changes in commodity prices, and tax and other government regulations. Investments in interests in oil, gas or mineral exploration or development programs, including pipelines, may be held through master limited partnerships (“MLPs”), which are generally subject to many of the risks that apply to partnerships and may also be subject to certain tax risks.

Limited Portfolio Risk
To the extent the Fund invests its assets in a more limited number of issuers than many other mutual funds, a decline in the market value of a particular security may affect the Fund’s value more than if the Fund invested in a larger number of issuers.

Mid-sized Companies Risk
Mid-sized companies may be subject to a number of risks not associated with larger, more established companies, potentially making their stock prices more volatile and increasing the risk of loss.
Fund Performance
The bar chart and table provide some indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year to year and by showing how the Fund’s average annual returns for 1, 5, and 10 years and since inception compare with those of two broad measures of market performance. The returns in the bar chart do not reflect the impact of sales loads. If they did, the returns would be lower than those shown. The Fund’s investment strategy and investment team changed on March 30, 2009. The Fund’s past performance (before and after taxes) is not an indication of future performance. Updated performance information for the Fund is available at www.rsinvestments.com or by calling 800-766-3863.

[1] No since inception performance return is shown for Class A shares because the inception date for Class A shares was prior to the inception date of the Russell 1000® Value Index.
[2] Since inception returns for the S&P 500® Index shown in the table are since May 31, 1972, the month end prior to the inception of Class A shares.
After-tax returns are shown for Class A shares only; after-tax returns for other classes will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.
