The Fund normally invests at least 80% of its assets (defined as net assets plus borrowing for investment purposes) in stock of non-U.S. companies in at least three foreign countries, which may include companies located or operating in established or emerging market countries. The Fund defines a non-U.S. company as one that is domiciled, has its principal place of business, derives at least 50% of its revenue or profits, or has at least 50% of its assets outside the U.S. The primary regions of investment are Western Europe, the United Kingdom, Japan, Canada, Australia and Asia. The Sub-Adviser generally constructs its portfolios by using proprietary econometric models and a proprietary optimization process that balances the trade-off between a stock?s expected return, its contribution to portfolio level risk, portfolio specific restrictions, and its opportunity costs relative to trading costs. Buys and sells occur when opportunities arise that improve the portfolio?s risk adjusted benchmark relative expected returns, net of amortized transaction costs. The Fund?s Sub-Adviser may engage in active and frequent trading of the Fund?s portfolio securities to achieve the Fund?s investment objective. The Fund may also engage in securities lending.
