Strategy. The Fund mainly invests in equity securities of issuers in emerging and developing markets throughout the world. Under normal market conditions, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in equity securities of issuers that are economically tied to an emerging market country, and in derivatives and other instruments that have economic characteristics similar to such securities. For purposes of the 80% investment policy, the Fund considers an emerging market country to be one whose economy or markets are generally considered emerging or developing. The Fund typically invests in at least three emerging market countries. At times, the Fund may invest up to 100% of its total assets in securities of issuers … Show more… The Fund mainly invests in equity securities of issuers in emerging and developing markets throughout the world. Under normal market conditions, the Fund will invest at least 80% of its net assets, plus borrowings for investment purposes, in equity securities of issuers that are economically tied to an emerging market country, and in derivatives and other instruments that have economic characteristics similar to such securities. For purposes of the 80% investment policy, the Fund considers an emerging market country to be one whose economy or markets are generally considered emerging or developing. The Fund typically invests in at least three emerging market countries. At times, the Fund may invest up to 100% of its total assets in securities of issuers in emerging and developing markets. In general, countries may be considered emerging or developing markets if they are included in any one of the Morgan Stanley Capital International (MSCI) emerging markets indices or excluded from an index that captures representation across developed market countries, classified as an emerging or developing market, or classified under a similar or corresponding classification, by organizations such as the International Monetary Fund, or have economies, industries and stock markets with similar characteristics as such countries. For purposes of the 80% investment policy discussed above, a determination that an issuer is economically tied to an emerging market country is based on factors including, but not limited to, geographic location of its primary trading markets, location of its assets, its domicile or its principal offices, or whether it receives revenues or profits from goods produced or sold from, or investments made or services performed in, an emerging or developing market. Such a determination can also be based, in whole or in part, on identification of an issuers securities within an index or other listing indicating its location in an emerging or developing market country, or on its country of risk being an emerging market country as determined by a third party service provider such as Bloomberg. The Fund may also invest in securities of issuers in less-developed emerging market countries that are not included in standard emerging market benchmarks or classifications and are traditionally less accessible to investors or in the early stages of capital market or economic development (such countries are commonly referred to as frontier market countries). Frontier market countries generally have smaller economies and less developed capital markets than traditional emerging and developing market countries. Investments in issuers in frontier market countries are included in the 80% of the Funds assets discussed in the investment policy above. The Fund seeks its investment objective by focusing on investments in securities of companies in emerging or developing markets that the Adviser believes are innovative in either, or a combination of, their products, services, processes, business models, management, use of technology, or approach to servicing geographic and consumer markets. The Fund invests primarily in common stocks, but can also invest in other equity securities, including preferred stocks, convertible securities, rights and warrants. The Fund can invest in common and preferred stocks and debt securities of U.S. companies. It can also hold U.S. corporate and government debt securities for defensive and liquidity purposes. The Fund may also purchase American Depositary Shares (ADS) as part of American Depositary Receipt (ADR) issuances. Under normal market conditions, the Fund currently does not expect to invest a significant amount of its assets in securities of U.S. issuers or debt of any issuer. The Fund may buy securities of issuers of any size, any market capitalization range and any industry or sector. Although the Fund can invest in securities of companies of any size and any market capitalization range, because innovative companies generally tend to have smaller market capitalizations, the Fund anticipates that it will generally have greater exposure to small- and mid-sized companies. The Funds common stock investments also include China A-shares (shares of companies based in mainland China that trade on the Shanghai Stock Exchange and the Shenzhen Stock Exchange). The Fund may invest in illiquid or thinly traded securities. The Fund may also invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933, as amended. The Fund can invest in derivative instruments, including forward foreign currency contracts to manage currency or exchange rate risk. In selecting investments for the Fund, the Adviser evaluates investment opportunities on a company-by-company basis. This approach includes fundamental analysis of a companys financial statements, management record, capital structure, operations, product development, and competitive position in its industry. The portfolio manager also looks for newer or established businesses that are entering, or expected to enter, into a growth cycle and have the potential for accelerating earnings growth or cash flow. The portfolio manager considers the effect of worldwide trends on the growth of particular business sectors and looks for companies that may benefit from those trends and seeks a diverse mix of industries and countries to help reduce the risks of foreign investing, such as currency fluctuations and stock market volatility. The portfolio manager takes a broad view that stretches across industries, sectors, companies and a companys operational functions, when considering whether a company is deemed to be innovative. The portfolio manager monitors individual issuers for changes in the factors above, which may trigger a decision to sell a security. These factors may vary in particular cases and may change over time. As part of the Funds investment process to implement its investment strategy in pursuit of its investment objective, the Funds portfolio manager may also consider both qualitative and quantitative environmental, social and governance (ESG) factors they believe to be material to understanding an issuers fundamentals, assess whether any ESG factors pose a material financial risk or opportunity to the issuer and determine whether such risks are appropriately reflected in the issuers valuation. This analysis may involve the use of third-party research as well as proprietary research. Consideration of ESG factors is just one component of the portfolio managers assessment of issuers eligible for investment and not necessarily determinative to an investment decision. Therefore, the Funds portfolio manager may still invest in securities of issuers that may be viewed as having a high ESG risk profile. The ESG factors considered by the Funds portfolio manager may change over time and one or more factors may not be relevant with respect to all issuers eligible for investment and ESG considerations may not be applied to all issuers or investments in the Fund.
