 and other investment-related costs may be more expensive in emerging markets than in many developed markets, which could reduce the Fund’s income from securities or debt instruments of emerging market country issuers. Governments of many emerging market countries have exercised and continue to exercise substantial influence over many aspects of the private sector. In some cases, the government owns or controls many companies, including some of the largest in the country. Accordingly, government actions

could have a significant effect on economic conditions in an emerging market country and on market conditions, prices and yields of securities in the Fund’s portfolio. Emerging market countries are more likely than developed market countries to experience political uncertainty and instability, including the risk of war, terrorism, nationalization, limitations on the removal of funds or other assets, or diplomatic developments that affect investments in these countries. No assurance can be given that adverse political changes will not cause the Fund to suffer a loss of any or all of its investments in emerging market countries or interest/dividend income thereon. Foreign investment in certain emerging market country securities is restricted or controlled to varying degrees. These restrictions or controls may at times limit or preclude foreign investment in certain emerging market country securities and increase the costs and expenses of the Fund. Certain emerging market countries require governmental approval prior to investments by foreign persons, limit the amount of investment by foreign persons in a particular issuer, limit the investment by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries and/or impose additional taxes on foreign investors. Certain emerging market countries may also restrict investment opportunities in issuers in industries deemed important to national interests. Emerging market countries may require governmental approval for the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. Also, because publicly traded debt instruments of emerging market issuers represent a relatively recent innovation in the world debt markets, there is little historical data or related market experience concerning the attributes of such instruments under all economic, market and political conditions. As reflected in the above discussion, investments in emerging market securities involve a greater degree of risk than, and special risks in addition to the risks associated with, investments in domestic securities or in securities of foreign developed countries.
