The Fund considers a security to be an emerging markets security if its country of risk is included within the Morningstar Emerging Markets Index?. The Fund focuses on stocks of large capitalization companies, but the Fund may invest in companies of any size. The Fund normally invests across a wide range of sectors and industries. The Sub-Adviser employs a growth style of equity management, which means that the Fund seeks to invest in companies with sustainable competitive advantages versus others, long-term structural growth drivers that will lead to above-average future cash flow growth, attractive cash flow returns on invested capital, and management teams focused on creating long-term value for shareholders. The Sub-Adviser also aims to invest in companies when they trade at a significant discount to the estimate of intrinsic value (i.e. companies with share prices trading significantly below what the portfolio manager believes the share price should be).
