With respect to such equity investments, 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.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund&#x2019;s 80% policy is non-fundamental and may not be changed without 60 days&#x2019; prior notice to shareholders.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund utilizes two strategies and under normal circumstances expects to invest approximately 50% of its total &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;assets in each strategy; provided, however, that from time to time, Fund management may alter the weightings if it &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;deems it prudent to do so based on market conditions, trends or movements or other similar factors.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;One strategy focuses on investments in commodity-linked derivatives.

The use of hedging &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may result in certain adverse tax consequences.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Tax Risk &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x2014; Certain aspects of the tax treatment of derivative instruments, including swap agreements and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;realizes from its investments.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Risks Specific to Certain Derivatives Used by the Fund&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Commodity-Linked Derivatives&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The value of a commodity-linked derivative investment typically is based upon &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the price movements of a commodity, a commodity futures contract or commodity index, or some other readily &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;measurable economic variable. The value of commodity-linked derivative instruments may be affected by changes &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in overall market movements, volatility of the underlying benchmark, changes in inflation, interest rates, or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;embargoes, tariffs and international economic, political and regulatory developments. The value of commodity-linked&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; derivatives will rise or fall in response to changes in the underlying commodity or related index. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Investments in commodity-linked derivatives may be subject to greater volatility than non-derivative based &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;can be no assurance that one will develop.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Commodity-linked derivatives also may be subject to credit and interest rate risks that in general affect the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;values of fixed-income securities. Therefore, at maturity, the Fund may receive more or less principal than it &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;originally invested. The Fund might receive interest payments that are more or less than the stated coupon &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;interest payments.&lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 24pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In connection with the Fund&#x2019;s direct and indirect investments in commodity-linked derivatives, the Fund will &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;attempt to manage its counterparty exposure so as to limit its exposure to any one counterparty. However, due to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the limited number of entities that may serve as counterparties (and which the Fund believes are creditworthy) at &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;any one time the Fund may enter into swap agreements with a limited number of counterparties and may invest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in commodity-linked notes issued by a limited number of issuers that will act as counterparties, which may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;increase the Fund&#x2019;s exposure to counterparty credit risk. There can be no assurance that the Fund will be able to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;limit exposure to any one counterparty at all times.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Commodity-Linked Notes&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Commodity-linked notes involve substantial risks, including the risk of loss of a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;significant portion of their principal value. In addition to commodity risk and general derivatives risk, they may be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;subject to additional special risks, such as risk of loss of interest and principal, lack of secondary market and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;risk of greater volatility, that do not affect traditional equity and debt securities.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Futures&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;primary risks associated with the use of futures contracts and options are: (a) the imperfect correlations &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;between the change in market value of the instruments held by the Fund and the price of the futures contract or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;option; (b) the possible lack of a liquid secondary market for a futures contract and the resulting inability to close &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;unlimited; (d) the investment adviser&#x2019;s inability to predict correctly the direction of securities prices, interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;default in the performance of its obligations.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Swaps&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Swap agreements, including total return swaps that may be referred to as contracts for difference, are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;two-party contracts entered into for periods ranging from a few days to more than one year. In a standard &#x201c;swap&#x201d; &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transaction, two parties agree to exchange the value(s) or cash flow(s) of one asset for another over a certain &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;period of time. Swap agreements involve the risk that the party with whom the Fund has entered into the swap &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;pay the other party to the agreement. Swap agreements may also involve the risk that there is an imperfect &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;correlation between the return on the Fund&#x2019;s obligation to its counterparty and the return on the referenced &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;asset. In addition, swap agreements are subject to market and illiquidity risk, leverage risk and hedging risk.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Forward Foreign Currency Exchange Contracts&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Forward foreign currency exchange transactions are OTC &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;contracts to purchase or sell a specified amount of a specified currency or multinational currency unit at a price &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and future date set at the time of the contract. Forward foreign currency exchange contracts do not eliminate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations in the value of non-U.S. securities but rather allow the Fund to establish a fixed rate of exchange for &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a future point in time. This strategy can have the effect of reducing returns and minimizing opportunities for gain.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

The value of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a security or other asset may decline due to changes in general market conditions, economic trends or events that &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issuers, exchange, country, group of countries, region, market, industry, group of industries, sector or asset class. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The success of the Fund&#x2019;s activities could be affected by interest rates, availability of credit, inflation rates, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;economic uncertainty, changes in laws, tariffs and trade barriers, supply chain disruptions, economic sanctions, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;currency exchange controls, and local, regional or global events such as war, acts of terrorism, natural and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;environmental disasters, the spread of infectious illness or other public health issues, recessions, or other events.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Recent policy initiatives undertaken by the U.S. government have the potential to impact international relations, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;trade agreements and the overall regulatory environment in ways that could create uncertainty and instability in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;domestic and global markets, and could adversely affect the investment performance of the Fund. In particular, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;actions taken by the U.S. government in respect of international trade relations could lead to trade wars, increased &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;costs for imported goods, disruptions in supply chains, reduced foreign investment, and instability in regions where &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the Fund invests.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

Because the Fund invests primarily in one &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;sector, there is the risk that the Fund will perform poorly during a downturn in that sector.&lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="margin-top: 2pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund&#x2019;s investments will be concentrated in a group of industries that make up the Commodities Sector. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Because the Fund is focused in specific industries, it may present more risks than if it were broadly diversified over &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;numerous industries and sectors of the economy. A downturn in the Commodities Sector would have a larger impact &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;on the Fund than on an investment company that does not concentrate in the industries or businesses in the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Commodities Sector. The industries and businesses in the Commodities Sector in which the Fund will concentrate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;its investments can be significantly affected by the supply of and demand for specific products and services, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;exploration and production spending, government regulation, world events and economic conditions. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Commodities Sector can also be significantly affected by events relating to international political developments, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;energy conservation, the success of exploration projects, commodity prices, and tax and government regulations. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The stock prices of commodity-related companies may also experience greater price volatility than other types of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;common stocks. Securities issued by commodity-related companies are sensitive to changes in the prices of, and in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;supply and demand for, the indicated commodities. The value of securities issued by commodity-related companies &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may be affected by changes in overall market movements, changes in inflation, interest rates, or factors affecting a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;particular industry or commodity, such as weather, embargoes, tariffs, policies of commodity cartels and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;international economic, political and regulatory developments. Fund management&#x2019;s judgments about trends in the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;prices of these securities and commodities may prove to be incorrect. At times, the performance of securities of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;companies in the Commodities Sector will lag behind the performance of other industries or the broader market as &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a whole.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

However, the Fund wholly &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;owns and controls the Subsidiary, and the Fund and the Subsidiary are both managed by BlackRock, making it &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;unlikely that the Subsidiary will take action contrary to the interests of the Fund and its shareholders.

The Subsidiary is subject to the same investment restrictions &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and limitations, and follows the same compliance policies and procedures, as the Fund, except that the Subsidiary &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;does not invest in equity securities of commodity-related companies, and may invest without limitation in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commodity-linked derivative instruments.

The Bloomberg Commodity Index Total Return&lt;span style="color: #000000; font-family: arial; font-size: 5pt; position: relative; top: -3.25pt;"&gt;SM&lt;/span&gt; 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 BlackRock and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

This includes companies that are engaged in businesses such as integrated oil, oil and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;gas exploration and production, energy services and technology, chemicals and oil products, coal and other &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;consumable fuel, gold and precious metals, metals and minerals, forest products, agricultural chemicals and services, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;farm land, alternative energy sources, environmental services and agricultural products (including crop growers, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;owners of plantations, and companies that produce and process foods), as well as related transportation companies, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equipment manufacturers, service providers and engineering, procurement and construction (&#x201c;EPC&#x201d;) companies.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund may make investments directly or through investments in the Subsidiary, a wholly-owned subsidiary of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Fund formed in the Cayman Islands.

Finally, BlackRock may not be able to predict correctly &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the direction of securities prices, interest rates and other economic factors, which could cause the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;derivatives positions to lose value.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Counterparty Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Derivatives are also subject to counterparty risk, which is the risk that the other party in the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transaction will be unable or unwilling to fulfill its contractual obligation, and the related risks of having concentrated &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;exposure to such a counterparty.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Illiquidity Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;difficult for the Fund to value accurately.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 12pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Operational Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The use of derivatives includes the risk of potential operational issues, including documentation &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;issues, settlement issues, systems failures, inadequate controls and human error.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Legal Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The risk of insufficient documentation, insufficient capacity or authority of counterparty, or legality or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;enforceability of a contract.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Volatility and Correlation Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Volatility is defined as the characteristic of a security, an index or a market to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuate significantly in price within a short time period. A risk of the Fund&#x2019;s use of derivatives is that the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations in their values may not correlate with the overall securities markets.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Valuation Risk &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x2014; Valuation for derivatives may not be readily available in the market. Valuation may be more difficult &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in times of market turmoil since many investors and market makers may be reluctant to purchase complex &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;instruments or quote prices for them.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Hedging Risk&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Hedges are sometimes subject to imperfect matching between the derivative and the underlying &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;security, and there can be no assurance that the Fund&#x2019;s hedging transactions will be effective. The use of hedging &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may result in certain adverse tax consequences.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Tax Risk &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;&#x2014; Certain aspects of the tax treatment of derivative instruments, including swap agreements and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;regulations or other legally binding authority. Such treatment may be less favorable than that given to a direct &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;realizes from its investments.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Risks Specific to Certain Derivatives Used by the Fund&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Commodity-Linked Derivatives&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; The value of a commodity-linked derivative investment typically is based upon &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the price movements of a commodity, a commodity futures contract or commodity index, or some other readily &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;measurable economic variable. The value of commodity-linked derivative instruments may be affected by changes &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in overall market movements, volatility of the underlying benchmark, changes in inflation, interest rates, or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;embargoes, tariffs and international economic, political and regulatory developments. The value of commodity-linked&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; derivatives will rise or fall in response to changes in the underlying commodity or related index. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Investments in commodity-linked derivatives may be subject to greater volatility than non-derivative based &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;investments. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;can be no assurance that one will develop.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Commodity-linked derivatives also may be subject to credit and interest rate risks that in general affect the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;values of fixed-income securities. Therefore, at maturity, the Fund may receive more or less principal than it &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;originally invested. The Fund might receive interest payments that are more or less than the stated coupon &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;interest payments.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;In connection with the Fund&#x2019;s direct and indirect investments in commodity-linked derivatives, the Fund will &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;attempt to manage its counterparty exposure so as to limit its exposure to any one counterparty. However, due to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the limited number of entities that may serve as counterparties (and which the Fund believes are creditworthy) at &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;any one time the Fund may enter into swap agreements with a limited number of counterparties and may invest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;in commodity-linked notes issued by a limited number of issuers that will act as counterparties, which may &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;increase the Fund&#x2019;s exposure to counterparty credit risk. There can be no assurance that the Fund will be able to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;limit exposure to any one counterparty at all times.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Commodity-Linked Notes&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Commodity-linked notes involve substantial risks, including the risk of loss of a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;significant portion of their principal value. In addition to commodity risk and general derivatives risk, they may be &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;subject to additional special risks, such as risk of loss of interest and principal, lack of secondary market and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;risk of greater volatility, that do not affect traditional equity and debt securities.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Futures&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;primary risks associated with the use of futures contracts and options are: (a) the imperfect correlations &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;between the change in market value of the instruments held by the Fund and the price of the futures contract or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;option; (b) the possible lack of a liquid secondary market for a futures contract and the resulting inability to close &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;unlimited; (d) the investment adviser&#x2019;s inability to predict correctly the direction of securities prices, interest &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;default in the performance of its obligations.&lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Swaps&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Swap agreements, including total return swaps that may be referred to as contracts for difference, are &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;two-party contracts entered into for periods ranging from a few days to more than one year. In a standard &#x201c;swap&#x201d; &lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; margin-left: 24pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;transaction, two parties agree to exchange the value(s) or cash flow(s) of one asset for another over a certain &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;period of time. Swap agreements involve the risk that the party with whom the Fund has entered into the swap &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;pay the other party to the agreement. Swap agreements may also involve the risk that there is an imperfect &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;correlation between the return on the Fund&#x2019;s obligation to its counterparty and the return on the referenced &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;asset. In addition, swap agreements are subject to market and illiquidity risk, leverage risk and hedging risk.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt;  &lt;div style="margin-top: 4pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;Forward Foreign Currency Exchange Contracts&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; &#x2014; Forward foreign currency exchange transactions are OTC &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;contracts to purchase or sell a specified amount of a specified currency or multinational currency unit at a price &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;and future date set at the time of the contract. Forward foreign currency exchange contracts do not eliminate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;fluctuations in the value of non-U.S. securities but rather allow the Fund to establish a fixed rate of exchange for &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a future point in time. This strategy can have the effect of reducing returns and minimizing opportunities for gain.&lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

Because the Fund invests primarily in one &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;sector, there is the risk that the Fund will perform poorly during a downturn in that sector.&lt;/span&gt; &lt;br/&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; &lt;/div&gt; &lt;div style="clear: both; position: relative;"&gt; &lt;/div&gt; &lt;/div&gt;  &lt;div style="margin-top: 2pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund&#x2019;s investments will be concentrated in a group of industries that make up the Commodities Sector. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Because the Fund is focused in specific industries, it may present more risks than if it were broadly diversified over &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;numerous industries and sectors of the economy. A downturn in the Commodities Sector would have a larger impact &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;on the Fund than on an investment company that does not concentrate in the industries or businesses in the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Commodities Sector. The industries and businesses in the Commodities Sector in which the Fund will concentrate &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;its investments can be significantly affected by the supply of and demand for specific products and services, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;exploration and production spending, government regulation, world events and economic conditions. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Commodities Sector can also be significantly affected by events relating to international political developments, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;energy conservation, the success of exploration projects, commodity prices, and tax and government regulations. &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The stock prices of commodity-related companies may also experience greater price volatility than other types of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;common stocks. Securities issued by commodity-related companies are sensitive to changes in the prices of, and in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;supply and demand for, the indicated commodities. The value of securities issued by commodity-related companies &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may be affected by changes in overall market movements, changes in inflation, interest rates, or factors affecting a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;particular industry or commodity, such as weather, embargoes, tariffs, policies of commodity cartels and &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;international economic, political and regulatory developments. Fund management&#x2019;s judgments about trends in the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;prices of these securities and commodities may prove to be incorrect. At times, the performance of securities of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;companies in the Commodities Sector will lag behind the performance of other industries or the broader market as &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;a whole.&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; line-height: 10.695pt;"&gt; &lt;/span&gt;&lt;/div&gt; </oef:RiskTextBlock>

Class K Shares commenced operations on January 25, 2018. As a result, the returns shown below for Class K Shares prior to January 25, 2018 are those of the Fund&#x2019;s Institutional Shares, which are not offered in this prospectus. The performance of Class K Shares would be substantially similar to Institutional Shares because Class K Shares and Institutional Shares are invested in the same portfolio of securities and performance &lt;/span&gt;&lt;/div&gt;  &lt;div style="line-height: 10.695pt; text-align: left;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;would differ only to the extent that Institutional Shares and Class K Shares have different expenses. The actual returns of Class K Shares would have been higher than those of the Institutional Shares because Class K Shares have lower expenses than Institutional Shares.

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. The table includes all applicable fees. If BlackRock and its affiliates had not waived or reimbursed certain Fund expenses during these periods, the Fund&#x2019;s returns would have been lower.

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any.

Such indices use withholding tax rates that are often at a higher rate than the rates to which the Fund is subject in each country, including for countries where the Fund is not subject to withholding taxes. When this is the case, index performance will be lower than if the index used the Fund&#x2019;s applicable withholding tax rates, if any. For additional comparative performance information for the MSCI All Country World Index, please see the Fund&#x2019;s Statement of Additional Information.</link:footnote>
