The Fund considers companies primarily engaged in natural resources and natural resources-related businesses to be those with a majority of assets, revenues or earnings, directly or indirectly through subsidiaries, from owning, producing, refining, processing, transporting, distributing, mining, exploring, storing, or otherwise handling natural resources, or from activities that directly rely on or support natural resources, such as producing food, delivering utilities, selling machines for natural resources uses, and deriving materials such as fertilizer, glass, paper and plastic. The Fund considers natural resources to generally include, but not be limited to, metals, agricultural products, timber, water, energy (including fossil fuel and renewable sources), and chemicals. The Fund invests more than 25% of its net assets, in aggregate, in companies primarily engaged in natural resources and natural resources-related industries. The Funds investments in equity securities may include common stocks, American depositary receipts (ADRs), European depositary receipts (EDRs), global depositary receipts (GDRs), non-voting depositary receipts (NVDRs), U.S. dollar-denominated foreign stocks traded on U.S. exchanges, and master limited partnerships. Using a combination of top-down and bottom-up analysis, the Funds sub-advisor, GLG LLC, an indirect wholly owned subsidiary of Man Group plc, invests in companies with historical track records of capital appreciation. The sub-advisor may also invest in companies based upon a belief that they are poised to increase in value following an anticipated event, such as a merger or acquisition. The Fund typically sells a security when the reasons for buying it no longer apply in the sub-advisors view, when the company begins to show deteriorating fundamentals or poor relative performance, or when the sub-advisor believes a security has reached its full market value. The Fund may also sell a security to secure gains, limit losses or redeploy assets into more promising opportunities. The Fund may have a focused portfolio ranging from 30 to 60 securities. The Fund may have significant exposure to the Energy and Materials sectors. However, as the sector composition of the Funds portfolio changes over time, the Funds exposure to these sectors may be lower at a future date, and the Funds exposure to other market sectors may be higher. The Fund principally invests in large and mid-capitalization companies, and to a lesser extent in small-capitalization companies. The Fund may invest in growth and value stocks. The Fund may invest without limitation in the United States and foreign developed and emerging market securities, and may have significant exposure to companies located in, or with economic ties to, Australia, Canada, Europe and the United Kingdom. However, as the geographic concentration of the Funds portfolio changes over time, the Funds exposure to Australia, Canada, Europe and the United Kingdom may decline, and the Funds exposure to other geographic areas may increase. The Funds investments in equity securities may be denominated in foreign currencies, and the Fund may invest directly in foreign currencies. The Fund may engage in active and frequent trading of portfolio securities to achieve its principal investment strategies. The Fund may invest cash balances in a government money market fund advised by the Manager, with respect to which the Manager receives a management fee. Show less
