The equity securities in which the Fund invests are predominantly common stock, and may include small and mid capitalization companies. Although the investment manager searches for investments across a large number of countries and sectors, from time to time, based on economic conditions, the Fund may have significant positions in particular countries or sectors, such as industrials. Under normal market conditions, the Fund invests predominantly in companies that are determined by the investment manager to exhibit superior practices in identifying, adapting and providing solutions to the consequences of climate change (i.e., companies that, based on the investment managers fundamental analysis and research, are able to successfully transition to a lower carbon economy). When choosing equity investments for the Fund, the investment manager applies a bottom-up, value-oriented, long-term approach, to select attractively valued companies preparing for a transition to a lower carbon economy. The investment manager focuses on the market price of the companys securities relative to the investment managers evaluation of the companys long-term earnings, asset value and cash flow potential. The investment manager also considers a companys price/earnings ratio, price/cash flow ratio, profit margins and liquidation value. The investment manager may consider selling an equity security when it believes the security price meets or exceeds its estimation of full value, greater value exists in another similar security or the company no longer meets the climate change inclusion criteria. The Fund may, from time to time, engage in (i) currency-related derivatives, such as currency and cross-currency forwards and currency futures contracts, to seek to hedge (protect) against currency risks, and (ii) equity-related derivatives, which may include equity futures and equity index futures, for various purposes including enhancing Fund returns, increasing liquidity and gaining exposure to individual securities and particular markets in more efficient or less expensive ways.
