You may qualify for sales charge discounts if you and an eligible group of investors purchase, or agree to purchase in the future, $25,000 or more in shares of the Fund or other funds in the Prudential Investments family of funds. More information about these discounts is available from your financial professional and is explained in Reducing or Waiving Class A's Initial Sales Charge on page 24 of the Fund's Prospectus and in the Fund's Statement of Additional Information (SAI), in Rights of Accumulation on page 43. <b>PRUDENTIAL JENNISON NATURAL RESOURCES FUND, INC.<br/><br/></b>FUND SUMMARY <b>INVESTMENT OBJECTIVE</b> <b>FUND FEES AND EXPENSES</b> The investment objective of the Fund is <b>long-term growth of capital.</b> <b>Shareholder Fees (fees paid directly from your investment)</b> <b>Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)</b> <b>Example.</b> The following hypothetical example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. It assumes that you invest $10,000 in the Fund for the time periods indicated and then, except as indicated, redeem all your shares at the end of those periods. It assumes a 5% return on your investment each year, that the Fund's operating expenses remain the same and that all dividends and distributions are reinvested. Your actual costs may be higher or lower. <b>If Shares Are Redeemed</b> <b>If Shares Are Not Redeemed</b> <b>Portfolio Turnover.</b> The Fund pays transaction costs, such as commissions, when it buys and sells securities (or &#8220;turns over&#8221; its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund's performance. During the Fund's most recent fiscal year, the Fund's portfolio turnover rate was 27% of the average value of its portfolio. &#176; The distributor of the Fund has contractually agreed until February 28, 2014 to reduce its distribution and service (12b-1) fees for Class R shares to .50% of the average daily net assets of Class R shares. This waiver may not be terminated by the distributor prior to February 28, 2014. The decision on whether to renew, modify or discontinue the waiver is subject to review by the distributor and the Fund&#8217;s Board of Directors. <b>INVESTMENTS, RISKS AND PERFORMANCE</b><br/><br/><b>Principal Investment Strategies.</b> Consistent with our investment objective, we look for investments that we think will increase in value over a period of years. The Fund normally invests at least 80% of investable assets in equity and equity-related securities of natural resource companies and in asset-based securities, as described below. Natural resource companies are U.S. and foreign (non-U.S. based) companies that own, explore, mine, process or otherwise develop, or provide goods and services with respect to, natural resources. Asset-based securities are securities, the values of which are related to the market value of a natural resource. The principal type of equity in which the Fund invests is common stock. In addition to common stock, equity and equity-related securities include preferred stock, rights that can be exercised to obtain stock, warrants and debt securities or preferred stock convertible into or exchangeable for common or preferred stock and interests in master limited partnerships. Generally, we consider selling a security when it no longer displays conditions for growth, is no longer undervalued or falls short of expectations. The Fund will provide 60 days&#8217; prior written notice to shareholders of a change in this non-fundamental policy. <b>Principal Risks of Investing in the Fund.</b> All investments have risks to some degree. Please remember that an investment in the Fund is not guaranteed to achieve its investment objective; is not a deposit with a bank; is not insured, endorsed or guaranteed by the Federal Deposit Insurance Corporation or any other government agency; and is subject to investment risks, including possible loss of your original investment.<br/><br/><b>Recent Market Events.</b> The financial crisis that began in 2008 has caused a significant decline in the value and liquidity of many securities. In response to the crisis, the U.S. and other governments and U.S. and foreign central banks have taken steps to support financial markets. The withdrawal of this support, failure of efforts in response to the crisis, or investor perception that such efforts are not succeeding could negatively affect financial markets generally as well as the value and liquidity of certain securities. In addition, policy and legislative changes in the United States and other countries are changing many aspects of financial regulation. The impact of these changes on the markets, and the practical implications for market participants, may not be fully known for some time.<br/><br/><b>Risk of Increase in Expenses.</b> Your actual cost of investing in the Fund may be higher than the expenses shown in the expense table for a variety of reasons. For example, expense ratios may be higher than those shown if average net assets decrease. Net assets are more likely to decrease and Fund expense ratios are more likely to increase when markets are volatile.<br/><br/><b>Special Risks of Investing in Natural Resource Companies.</b> The Fund&#8217;s investments in securities of natural resource companies involve risks. The market value of securities of natural resource companies may be affected by numerous factors, including events occurring in nature, inflationary pressures and international politics. Because the Fund invests primarily in companies with natural resource assets, there is the risk that the Fund will perform poorly during a downturn in natural resource companies. For example, events occurring in nature (such as earthquakes or fires in prime natural resource areas) and political events (such as coups, military confrontations or acts of terrorism) can affect the overall supply of a natural resource and the value of companies involved in such natural resource. Political risks and the other risks to which foreign securities are subject may also affect domestic companies in which we invest if they have significant operations or investments in foreign countries. In addition, rising interest rates and general economic conditions may affect the demand for natural resources.<br/><br/><b>Nondiversification Risk.</b> The Fund is nondiversified. This means that the Fund may invest a greater percentage of its assets in the securities of a single company or other issuer than a diversified fund. Investing in a nondiversified fund involves greater risk than investing in a diversified fund because a loss resulting from the decline in value of any one security may represent a greater portion of the total assets of a nondiversified fund.<br/><br/><b>Management Risk.</b> The value of your investment may decrease if judgments by the subadviser about the attractiveness, value or market trends affecting a particular security, industry or sector or about market movements are incorrect.<br/><br/><b>Equity and Equity-Related Securities Risks.</b> There is the risk that the value of a particular security could go down and you could lose money. In addition to an individual security losing value, the value of the equity markets or a sector in which the Fund invests could go down. The Fund's holdings can vary significantly from broad market indexes and the performance of the Fund can deviate from the performance of these indexes. Different parts of a market can react differently to adverse issuer, market, regulatory, political and economic developments.<br/><br/>The Fund may invest in companies that reinvest their earnings rather than distribute them to shareholders. To the extent the Fund does invest in such companies, the Fund is not likely to receive significant dividend income on its portfolio securities.<br/><br/><b>Market Risk.</b> The securities markets are volatile and the market prices of the Fund&#8217;s securities may decline generally. Securities fluctuate in price based on changes in a company&#8217;s financial condition and overall market and economic conditions. If the market prices of the securities owned by the Fund fall, the value of your investment in the Fund will decline.<br/><br/><b>Foreign Securities Risk.</b> The Fund&#8217;s investments in securities of foreign issuers or issuers with significant exposure to foreign markets involve additional risk. Foreign countries in which the Fund may invest may have markets that are less liquid, less regulated and more volatile than U.S. markets. The value of the Fund&#8217;s investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, and political or financial instability. Lack of information may also affect the value of these securities. We do not consider American Depositary Receipts (&#8220;ADRs&#8221;), American Depositary Shares (&#8220;ADSs&#8221;) and other similar receipts or shares traded in U.S. markets in which the Fund may invest to be foreign securities.<br/><br/>For more information on the risks of investing in this Fund, including the risks of foreign securities, please see How the Fund Invests&#8212;Investment Risks in the Prospectus and Investment Risks and Considerations in the SAI. <b>The Fund's Past Performance.</b> The following bar chart shows the Fund's performance for the indicated share class for each full calendar year of operations or for the last 10 calendar years, whichever is shorter. The bar chart and Average Annual Total Returns table demonstrate the risk of investing in the Fund by showing how returns can change from year to year and by showing how the Fund's average annual total returns for the share class compare with a broad-based securities market index and a group of similar mutual funds. <br/><br/>Past performance (before and after taxes) does not mean that the Fund will achieve similar results in the future.
