The Investment Adviser considers an equity investment to be tied economically to China if the investment is included in an index representative of China, the investment’s returns are linked to the performance of such an index, or the investment is exposed to the economic risks and returns of China. </p> <p>An issuer participates in the markets of China if the issuer: </p> <p>• Has a class of its securities whose principal securities market is in China; </p> <p>• Is organized under the laws of, or has a principal office in China; </p> <p>• Derives 50% or more of its total revenue from goods produced, sales made or services provided in China; or </p> <p>• Maintains 50% or more of its assets in China. </p> <p>The Fund expects to invest primarily in equity securities, including common or ordinary stocks, American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), European Depositary Receipts (“EDRs”), Taiwanese Depositary Receipts (“TDRs”), preferred stock, convertible securities, investment companies (including other mutual funds or exchange-traded funds (“ETFs”)), and rights and warrants. The Fund’s equity investments may also include equity swaps, equity index swaps, futures, participation notes, options and other derivatives and structured securities to gain broad access to markets that may be difficult to access via direct investment in equity securities. Only securities open to U.S. investors are eligible for investment by the Fund. </p> <p>The Fund’s investments are selected using a strong valuation discipline based on industry specific metrics to purchase what the Investment Adviser believes are well-positioned, cash-generating businesses run by shareholder-oriented management teams. From a valuation perspective, the Investment Adviser generally looks for companies where its proprietary estimate of their earnings, asset value or cash flow is meaningfully different from consensus; or where the Investment Adviser believes growth in intrinsic value is not reflected in the share price. Allocation of the Fund’s investments is determined by the Investment Adviser’s assessment of a company’s upside potential and downside risk, how attractive it appears relative to other holdings, and how the addition will impact sector and industry weightings. The largest overweights are given to companies the Investment Adviser believes have the most upside return potential relative to their contribution to overall portfolio risk. The Fund’s investments may include companies of all capitalization sizes. </p> <p>The Fund will not invest more than 25% of the value of the Fund’s total assets in the securities of one or more issuers conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark index at the time of investment, the Fund may invest up to 35% of its assets in that industry. The Fund may invest in the aggregate up to 20% of its Net Assets in investments in developed countries and emerging countries other than China, including non-investment grade fixed income securities. </p> <p>THE FUND IS “NON-DIVERSIFIED” UNDER THE INVESTMENT COMPANY ACT OF 1940 (“INVESTMENT COMPANY ACT”), AND MAY INVEST MORE OF ITS ASSETS IN FEWER ISSUERS THAN “DIVERSIFIED” MUTUAL FUNDS.</p>falsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringPrincipal investment strategies of the Fund.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective.</p> <p><i><b>Currency Risk.</b></i> Changes in currency exchange rates may adversely affect the value of the Fund’s securities denominated in foreign currencies. Currency exchange rates can be volatile. The Fund may from time to time attempt to hedge all or a portion of its currency risk using a variety of techniques, including currency futures, forwards, and options. However, these instruments may not always work as intended, and in certain cases the Fund may be worse off than if it had not used a hedging instrument. </p> <p><i><b>Depositary Receipts Risk.</b></i> Foreign securities may trade in the form of depositary receipts, including ADRs, GDRs, EDRs and TDRs (collectively, “Depositary Receipts”). In addition to the risks inherent in the underlying securities represented by the Depositary Receipts, in some situations there may be an increased possibility that the Fund would not become aware of and be able to respond to corporate actions involving the foreign issuer in a timely manner. Also, a lack of information may result in inefficiencies in the valuation of such instruments. Investment in Depositary Receipts does not eliminate all the risks inherent in investing in securities of non-U.S. issuers. </p> <p><i><b>Derivatives Risk.</b></i> Loss may result from the Fund’s investments in equity swaps, equity index swaps, futures, participation notes, options and structured securities and other derivative instruments. These instruments may be illiquid, difficult to price and leveraged so that small changes may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. </p> <p><i><b>Emerging Countries Risk.</b></i> The securities markets of emerging countries are less liquid, are especially subject to greater price volatility, have smaller market capitalizations, have less government regulation and are not subject to as extensive and frequent accounting, financial and other reporting requirements as the securities markets of more developed countries. </p> <p><i><b>Foreign Risk.</b></i> Foreign securities may be subject to risk of loss because of less foreign government regulation, less public information and less economic, political and social stability in these countries. Loss may also result from the imposition of exchange controls, confiscations and other government restrictions, or from problems in registration, settlement or custody. </p> <p><i><b>Greater China Risk.</b></i> Investing in Greater China (the People’s Republic of China, Hong Kong and Taiwan) involves a higher degree of risk and special considerations not typically associated with investing in other more established economies or securities markets. The Fund’s investment exposure to Greater China may subject the Fund, to a greater extent than if investments were made in developed countries, to the risks of adverse securities markets, exchange rates and social, political, regulatory, economic or environmental events or natural disasters which may occur in the China region. The economy, industries, and securities and currency markets of Greater China may be adversely impacted by protectionist trade policies, slow economic activity worldwide, dependence on exports and international trade, increasing competition from Asia’s other low-cost emerging economies, political and social instability, regional and global conflicts, terrorism and war, including actions that are contrary to the interests of the U.S.</p> <p>The securities markets of the People’s Republic of China and Taiwan are emerging markets characterized by a relatively small number of equity issues and relatively low trading volume, resulting in substantially less liquidity and greater price volatility and potentially fewer investment opportunities for the Fund. The government of the People’s Republic of China exercises significant control over the economy, and may alter laws or policies or discontinue economic reforms at any time. Taiwan and Hong Kong do not exercise the same level of control over their economies as does the People’s Republic of China, but changes to their political and economic relationships with the People’s Republic of China could adversely impact the Fund’s investments in Taiwan and Hong Kong. </p> <p><i><b>Industry Concentration Risk.</b></i> The Fund will not invest more than 25% of the value of the Fund’s total assets in the securities of one or more issuers conducting their principal business activities in the same industry, except that, to the extent that an industry represents 20% or more of the Fund’s benchmark index at the time of investment, the Fund may invest up to 35% of its assets in that industry. Concentrating Fund investments in a limited number of issuers conducting business in the same industry will subject the Fund to a greater risk of loss as a result of adverse economic, business or other developments affecting that industry than if its investments were not so concentrated. </p> <p><i><b>Liquidity Risk.</b></i> The Fund may make investments that may be illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. </p> <p><i><b>Market Risk.</b></i> The value of the instruments in which the Fund invests may go up or down in response to the prospects of individual companies, particular industry sectors or governments and/or general economic conditions. </p> <p><i><b>Mid-Cap and Small-Cap Risk.</b></i> The securities of mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks. </p> <p><i><b>NAV Risk.</b></i> The net asset value (“NAV”) of the Fund and the value of your investment may fluctuate. </p> <p><i><b>Non-Diversification Risk.</b></i> The Fund is non-diversified and is permitted to invest more of its assets in fewer issuers than a “diversified” mutual fund. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio, and may be more susceptible to greater losses because of these developments.</p> <p><i><b>Participation Notes Risk.</b></i> Participation notes are designed to track the return of a particular underlying equity or debt security, currency or market. Investments in participation notes involve the same risks associated with a direct investment in the underlying security, currency or market that they seek to replicate.
