Strategy. Under normal market conditions, the Fund invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies located in emerging market countries (the 80% Policy). A company will be considered to be located in an emerging market country if it is domiciled in and tied economically to one or more emerging market countries and may include a companys stock which is trading in the form of a depositary receipt. Emerging market countries are generally countries not considered to be developed market countries, and therefore not included in the MSCI World Index.

A company will be considered to be located in an emerging market country if it is domiciled in and tied economically to one or more emerging market countries and may include a companys stock which is trading in the form of a depositary receipt. Emerging market countries are generally countries not considered to be developed market countries, and therefore not included in the MSCI World Index. The Fund intends to invest primarily in securities issued by companies located in countries included in the MSCI Emerging Markets Index or the MSCI Frontier Markets Index. The MSCI Emerging Markets Index is an unmanaged index of common stocks of issuers in emerging markets countries. The MSCI Frontier Markets Index is an unmanaged index of common stocks of issuers in countries that have less-developed economies and financial markets than more established emerging markets, and often have more restrictions on foreign stock ownership. Securities acquired by the Fund are typically listed on stock exchanges in emerging market countries, but also may include securities traded in markets outside these countries. The Fund may invest in securities issued by companies with a broad range of market capitalizations, including those of smaller, less seasoned companies. More than 25% of the Funds total assets may be denominated in any single currency. The Fund may invest in exchange-traded funds (ETFs), a type of pooled investment vehicle, in order to manage cash positions or seek exposure to certain markets or market sectors. The Fund may also invest in publicly traded real estate investment trusts (REITs). The Fund may also lend its securities. The Fund seeks to employ a top-down, disciplined and systematic investment process that emphasizes broad exposure and diversification among emerging market countries, economic sectors and issuers. This rules-based strategy utilizes targeted allocation and systematic rebalancing to take advantage of certain quantitative and behavioral characteristics of emerging markets identified by the portfolio managers. The investment process is periodically re-evaluated and may be adjusted to ensure that the process is consistent with the Funds investment objective and strategies. The portfolio managers select and allocate across countries based on factors such as size, liquidity, level of economic development, local economic diversification, and perceived risk and potential for growth. The Fund maintains a bias to broad inclusion; that is, the Fund intends to allocate its portfolio holdings to more emerging market countries rather than fewer emerging market countries. Relative to capitalization-weighted country indexes, the Funds individual country allocation targets seek to emphasize the less represented emerging market countries and attempt to reduce concentration risks relative to a capitalization-weighted index. The Funds country allocations are typically rebalanced to their target weights if they exceed a certain pre-determined overweight or fall below a certain pre-determined underweight. Rebalancing is intended to reduce exposure to countries with strong relative performance and increasing exposure to countries which have underperformed. The frequency of rebalancing depends on the volatility and trading costs of the individual country. At the portfolio level and within each country, the Fund seeks to maintain exposure across key economic sectors. Relative to capitalization-weighted country indexes, the portfolio managers target weights to these sectors to emphasize the less represented sectors. The portfolio managers use a quantitative model to select individual securities as representatives of their economic sectors and generally weigh them by their relative capitalization within that sector.
