Strategy. To pursue its goal, the Fund invests primarily in equity securities of large-capitalization companies, which it defines as companies that have a market capitalization within the market capitalization range of companies in the Russell 1000 Index at the time of initial purchase. The Portfolio Managers seek to invest in a broad group of securities that have the potential to outperform the Russell 1000 Index with a lower level of risk through security selection. The Fund generally seeks to be sector neutral when compared to the Russell 1000 Index (i.e., having sector exposures similar to the Russell 1000 Index).

The Portfolio Managers seek to invest in a broad group of securities that have the potential to outperform the Russell 1000 Index with a lower level of risk through security selection. The Fund generally seeks to be sector neutral when compared to the Russell 1000 Index (i.e., having sector exposures similar to the Russell 1000 Index). The Portfolio Managers, with the assistance of the Managers research analysts, select securities for the Fund by using a fundamental, research-driven approach. The research analysts analyze and rate stocks within an industry by conducting equity research, which may include, but is not limited to, company visits, management interviews, industry conferences, proprietary modeling of earnings, cash flow and balance sheets, projecting growth and valuation changes, and setting price targets for companies under coverage. In selecting securities for the Fund, the Portfolio Managers utilize the analysis and ratings of the research analysts as they seek to maintain a sector neutral portfolio with what they believe are the most attractive investments in each industry. While the Fund will mainly invest in common stocks of U.S. companies, the Fund may invest in other types of equity securities, including real estate investment trusts, rights and warrants, exchange traded funds, and depository receipts. The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund. As part of their fundamental investment analysis the Portfolio Managers consider environmental, social and governance factors they believe are financially material to individual investments, where applicable. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material environmental, social and governance factors, alongside traditional financial metrics, may enhance the Funds overall investment process. The consideration of environmental, social and governance factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of environmental, social and governance factors as part of the investment process does not mean that the Fund pursues a specific impact or sustainable investment strategy. The Portfolio Managers may sell securities when they believe that they no longer represent attractive investment opportunities. The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities and other investment companies that provide investment exposure to equity securities without providing shareholders at least 60 days notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
