Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It illustrates the hypothetical expenses that you would incur over various periods if you invested $10,000 in the Fund’s shares. This example assumes that the Fund provides a return of 5% each year and that total annual fund operating expenses remain as stated in the preceding table. You would incur these hypothetical expenses whether or not you redeem your investment at the end of the given period. Although your actual costs may be higher or lower, based on these assumptions your costs would be:


1 Year	3 Years	5 Years	10 Years
$36	$113	$197	$443

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in more taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the previous expense example, reduce the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Fund invests at least 80% of its assets in the stocks of foreign and U.S. companies principally engaged in the exploration, mining, development, fabrication, processing, marketing, or distribution of (or other activities related to) metals or minerals. The majority of these companies will be principally engaged in activities related to gold, silver, platinum, diamonds, or other precious and rare metals or minerals. The remaining companies will be principally engaged in activities related to nickel, copper, zinc, or other base and common metals or minerals. Up to 100% of the Fund’s assets may be invested in foreign securities. The Fund may also invest up to 20% of its assets directly in gold, silver, or other precious metal bullion and coins.

Principal Risks

An investment in the Fund could lose money over short or even long periods. You should expect the Fund’s share price and total return to fluctuate within a wide range. The Fund is subject to the following risks, which could affect the Fund’s performance:

• Nondiversification risk, which is the chance that the Fund’s performance may be hurt disproportionately by the poor performance of relatively few stocks or even a single stock. The Fund is considered nondiversified, which means that it may invest a greater percentage of its assets in the securities of particular issuers as compared with other mutual funds. Because the Fund tends to invest a high percentage of assets in its ten largest holdings, nondiversification risk is very high for the Fund.

• Industry concentration risk, which is the chance that there will be particular problems affecting an entire industry. Any fund that concentrates in a particular industry will generally be more volatile than a fund that invests more broadly. Because the Fund normally invests at least 80% of its assets in the metals or minerals industries, the Fund’s performance largely depends—for better or for worse—on the overall condition of those industries. The metals or minerals industries could be affected by sharp price volatility caused by global economic, financial, and political factors. Resource availability, government regulation, and economic cycles could also adversely affect those industries.

• Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. The Fund’s investments in foreign stocks can be riskier than U.S. stock investments. Foreign stocks tend to be more volatile and less liquid than U.S. stocks. The prices of foreign stocks and the prices of U.S. stocks may move in opposite directions.

• Investment style risk, which is the chance that returns from small- and mid-capitalization stocks will trail returns from global stock markets. Historically, small- and mid-cap stocks have been more volatile in price than the large-cap stocks that dominate the global markets, and they often perform quite differently. Small and mid-size companies tend to have greater stock volatility because, among other things, these companies are more sensitive to changing economic conditions.

• Manager risk, which is the chance that poor security selection will cause the Fund to underperform relevant benchmarks or other funds with a similar investment objective.

• Country/regional risk, which is the chance that world events—such as political upheaval, financial troubles, or natural disasters—will adversely affect the value of securities issued by companies in foreign countries or regions.

• Currency risk, which is the chance that the value of a foreign investment, measured in U.S. dollars, will decrease because of unfavorable changes in currency exchange rates.

An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
