These&amp;#160;factors include events impacting a single issuer,&#13;as well as political, market and economic developments that affect specific market segments and the stock market as a whole. The&#13;Worldwide Fund&amp;#146;s NAV, like stock prices generally, will fluctuate within a wide range in response to these factors. As a&#13;result, an investor in the Worldwide Fund could lose money over short or even long periods.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Tax Risks.&lt;/b&gt; To qualify as a regulated&#13;investment company for income tax purposes, income derived from investing or trading in precious metals, together with any other&#13;non-qualifying income received by the Worldwide Fund in any tax year, must not exceed 10% of the Worldwide Fund&amp;#146;s gross income&#13;for such year. If the Worldwide Fund fails to meet these requirements, it would: (i) not qualify as a regulated investment company;&#13;(ii) incur regular corporate income tax on its taxable income for that year; (iii) lose its deduction for dividends paid to shareholders;&#13;and (iv) be subject to certain gain recognition and distribution requirements upon requalification. Further distributions of income&#13;by the Worldwide Fund to its shareholders would be treated as dividend income.

An investment in the International Fund is not a bank deposit and is not insured or guaranteed&#13;by the Federal Deposit Insurance Corporation or any other government agency.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Debt Securities Risk.&lt;/b&gt; Risks associated&#13;with investments in fixed income securities include credit risk, interest rate risk, liquidity risk and the risk of default, particularly&#13;with respect to high yield securities.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Derivative Investment Risk.&lt;/b&gt; Derivatives&#13;are subject to a number of risks, such as interest rate risk, market risk, credit risk, foreign exchange risk and management risk.&#13;Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index, and the International&#13;Fund may lose more money than it invested in the derivative. A small investment in a derivative could have a relatively large&#13;positive or negative impact on the performance of the Fund, potentially resulting in losses to Fund shareholders.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&#13;&lt;b&gt;Emerging Markets Risk.&lt;/b&gt; Securities listed and traded in&amp;#160;emerging markets are subject to additional risks associated&#13;with emerging market economies. Such risks may include: (i) greater market volatility; (ii) lower trading volume; (iii) greater&#13;social, political and economic uncertainty; (iv) governmental controls on foreign investments and limitations on repatriation&#13;of invested capital; (v) the risk that companies may be held to lower disclosure, corporate governance, auditing and financial&#13;reporting standards than companies in more developed markets; and (vi) the risk that there may be less protection of property&#13;rights than in other countries.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Foreign Securities Risk.&lt;/b&gt; Foreign securities&#13;can involve additional risks&amp;#160;relating to political, economic or regulatory conditions in foreign countries. These risks include&#13;fluctuations in foreign currencies; withholding or other taxes; trading, settlement, custodial, and other operational risks; and&#13;the less stringent investor protection and disclosure standards of some foreign markets.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Investment Style Risk.&lt;/b&gt; The returns&#13;from the types of securities in which the International Fund invests may underperform returns from the various general securities&#13;markets or different asset classes. This may cause the International Fund to underperform other investment vehicles that invest&#13;in different asset classes.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Issuer-Specific Risk.&lt;/b&gt; Changes in the&#13;financial condition of an issuer or counterparty, changes in specific&amp;#160;economic or political conditions that affect a particular&#13;type of security or issuer, and changes in general economic or political conditions can affect a security&amp;#146;s or instrument&amp;#146;s&#13;value. The value of securities or instruments of smaller, less-well-known issuers can be more volatile than that of larger issuers.&#13;Issuer-specific events can have a negative impact on the value of the International Fund.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&#13;&lt;b&gt;Large-Capitalization Investing&lt;/b&gt;. Large-capitalization stocks as a group could fall out of favor with the market, causing&#13;the International Fund to underperform investments that focus on small- or medium-capitalization stocks. Larger, more established&#13;companies may be slow to respond to challenges and may grow more slowly than smaller companies.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Management Risk.&lt;/b&gt; This is the risk that&#13;the International Fund&amp;#146;s investment strategy, the implementation of which is subject to a&amp;#160;number of internal and external&#13;constraints, may not produce the desired results, including the risk that the International Fund&amp;#146;s portfolio managers&amp;#146;&#13;judgments about asset allocations may not be correct and could adversely affect the International Fund&amp;#146;s performance.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Precious Metals Risk.&lt;/b&gt; Prices of precious&#13;metals and of precious metal related securities historically have been&amp;#160;very volatile. The production and sale of precious&#13;metals by governments or central banks or other larger holders can be affected by various economic, financial, social and political&#13;factors, which may be unpredictable and may have a significant impact on the prices of precious&#13;metals. Other factors that may affect the prices of precious metals and securities related to them include changes in inflation,&#13;the outlook for inflation and changes in industrial and commercial demand for precious metals.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Rule 144A Securities Risk.&lt;/b&gt; Rule 144A&#13;securities may have an active trading market, but carry the risk that the active trading market may not continue. To the extent&#13;that qualified institutional buyers become for a time uninterested in purchasing these securities, they will become illiquid while&#13;held by the International Fund.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Small and Mid-Capitalization Investing.&lt;/b&gt;&#13;The securities of small- and mid-capitalization companies may be subject to more unpredictable price changes than securities of&#13;larger companies or the market as a whole.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Stock Market Risk.&lt;/b&gt; The trading prices&#13;of equity securities fluctuate in response to a variety of factors. These&amp;#160;factors include events impacting a single issuer,&#13;as well as political, market and economic developments that affect specific market segments and the stock market as a whole. The&#13;International Fund&amp;#146;s NAV, like stock prices generally, will fluctuate within a wide range in response to these factors. As&#13;a result, an investor in the International Fund could lose money over short or even long periods.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&lt;b&gt;Tax Risks.&lt;/b&gt; To qualify as a regulated&#13;investment company for income tax purposes, income derived from investing or trading in precious metals, together with any other&#13;non-qualifying income received by the International Fund in any tax year, must not exceed 10% of the International Fund&amp;#146;s&#13;gross income for such year. If the International Fund fails to meet these requirements, it would: (i) not qualify as a regulated&#13;investment company; (ii) incur regular corporate income tax on its taxable income for that year; (iii) lose its deduction for dividends&#13;paid to shareholders; and (iv) be subject to certain gain recognition and distribution requirements upon requalification. Further&#13;distributions of income by the International Fund to its shareholders would be treated as dividend income. This tax requirement&#13;may cause the International Fund to hold or sell precious metals or securities when it would not otherwise do so.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt Times New Roman, Times, Serif; margin-right: 0; margin-left: 0"&gt;&#13;&lt;b&gt;U.S. Government Regulation Risk.&lt;/b&gt; The 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act (the &amp;#147;Dodd-Frank&#13;Act&amp;#148;) has resulted in significant revisions of the U.S. financial regulatory framework. The ultimate impact of the Dodd-Frank&#13;Act, and any resulting regulation, is not yet certain and issuers in which the International Fund invests may also be affected&#13;by the new legislation and regulation in ways that are currently unforeseeable.&lt;br /&gt; &lt;/p&gt;</rr:RiskNarrativeTextBlock>
