Under normal circumstances, the Fund will invest at least 80% of its assets in companies with substantial natural resource assets or in securities the value of which is related to the market value of some natural resource asset. Investments in derivatives are counted toward the Fund&#x2019;s 80% policy to the extent that they provide investment exposure to the securities included within that policy or to one or more market risk factors associated with such securities. Equity securities include common stock, preferred stock, rights to subscribe for common stock, and derivative securities or instruments, such as options, the value of which is based on a common stock or group of common stocks. The Fund may also purchase securities convertible into common stock. Natural resource assets include materials with economic value that are derived from natural sources, either directly or indirectly, such as precious metals (e.g., gold, silver and platinum), ferrous and nonferrous metals (e.g., iron, aluminum and copper), strategic metals (e.g., uranium and titanium), water, hydrocarbons (e.g., coal, oil and natural gas), timber land, underdeveloped real property and agricultural products (e.g., fertilizers and agricultural chemicals). The Fund normally invests in a portfolio consisting of companies in a variety of natural resource related sectors, such as energy, chemicals, oil, gas, paper, mining, steel or agricultural products. Under certain circumstances, however, the Fund may concentrate its investments in one or more of these sectors. In addition, the Fund will concentrate its investments in one or more issuers in the natural resources related industries. The Fund focuses on investments in companies that provide exposure to commodities where existing, and projected, capacity is forecast to approach levels that represent full utilization of that capacity based upon supply and demand forecasts for the commodity. The Fund will normally invest in both U.S. and non-U.S. companies, including companies located in emerging markets, and in securities denominated in both U.S. dollars and foreign currencies. The Fund may invest in securities of issuers with any market capitalization.&lt;/span&gt;&lt;/div&gt; </oef:StrategyNarrativeTextBlock>

Although the market price of these securities &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;is expected to follow the market price of the related resource, there may not be perfect correlation.

Other factors that may affect the prices of precious metals and securities related to them include &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt; </oef:RiskTextBlock>

The table compares the Fund&#x2019;s performance to that of the MSCI All Country World Index (Net) and the S&amp;amp;P Global Natural Resources Index (Net). The S&amp;amp;P Global Natural Resources Index (Net) is relevant to the Fund because it has characteristics similar to the Fund&#x2019;s investment strategy. To the extent that dividends and distributions have been paid by the Fund, the performance information for the Fund in the chart and table assumes reinvestment of the dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. If the Fund&#x2019;s investment manager and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower. Updated information on the Fund&#x2019;s performance, including its current net asset value, can be obtained by visiting www.blackrock.com or can be obtained by phone at (800) 882-0052.&lt;/span&gt;&lt;/div&gt; </oef:PerformanceNarrativeTextBlock>
