Principal investment strategy

The Fund invests primarily in common stocks of U.S. companies of different capitalization ranges. The Funds subadviser, OFI Global Institutional, Inc. (OFI Global), currently focuses on large capitalization issuers, which are considered to be companies with market capitalizations at the time of purchase within the market capitalization range of companies included within the Russell 1000 Index (as of December 31, 2017, $654 million to $867.51 billion), although it may purchase stocks of companies with any market capitalization. The Fund typically invests most of its assets in equity securities of U.S. companies, but may invest in foreign securities. The Fund generally will not invest more than 15% of its total assets in foreign securities. The Fund may hold a portion of its assets in cash or cash equivalents.

While the process may change over time or vary in particular cases, in general the selection process currently uses: a fundamental approach in analyzing issuers based on factors such as a companys financial performance and prospects, industry position, and business model and management strength.

A number of company-specific factors are analyzed in constructing the models, including valuation, fundamentals and momentum.
