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.&#160;The Fund determines that an investment is tied economically to a developed market if such investment satisfies one or more of the following conditions: 1) the issuer&#x2019;s primary trading market is in a developed market; 2) the issuer is organized under the laws of, derives at least 50% of its revenue from, or has at least 50% of its assets in developed markets; 3) the investment is included in an index representative of developed markets; and 4) the investment is exposed to the economic risks and returns of developed markets. The Fund may invest in securities of issuers of any market capitalization and in securities denominated in either U.S. dollars or foreign currencies. &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 intends to be market-neutral, which means that the Fund seeks to produce returns that have a low &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;correlation to the returns of the equity markets in which the Fund invests. The Fund pursues this market-neutral &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;strategy by taking both long and short positions in a variety of developed market equity instruments. The Fund expects &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;to maintain long and short positions primarily through the use of swap agreements and other derivative instruments, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;such as futures, and may invest in such instruments without limitation. Although the Fund intends to maintain an &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;overall long position in its portfolio investments, the Fund generally expects to maintain significant short positions in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equity securities and equity-related instruments. In certain circumstances, these short positions may approach or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;reach the size of the overall long position. A long position arises where the Fund holds a security in its portfolio or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;maintains a position through a derivative instrument that provides economic exposure similar to direct ownership of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the security. The Fund will have a short position where it sells a security it does not own by delivery of a borrowed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;security or has entered into a derivative instrument that provides economic exposure similar to a short sale of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;security. The Fund looks to identify overvalued, undervalued or mispriced stocks and other equity instruments through &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;proprietary ranking techniques. The Fund takes long positions primarily in securities that BlackRock has identified as &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;attractive and short positions in such securities that BlackRock has identified as overvalued or poised for &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;underperformance.&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;Under normal circumstances, the Fund anticipates it will allocate a substantial amount (approximately 40% or more &#x2014; &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;unless market conditions are not deemed favorable by BlackRock, in which case the Fund would invest at least 30%) &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;of its total assets in securities (or derivatives with similar economic characteristics) of (i) foreign government issuers, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;(ii) issuers organized or located outside the United States, (iii) issuers whose securities primarily trade in a market &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;located outside the United States, or (iv) issuers doing a substantial amount of business outside the United States, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;which the Fund considers to be companies that derive at least 50% of their revenue or profits from business outside &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;the United States or have at least 50% of their sales or assets outside the United States. The Fund will allocate its &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;assets among various regions and countries, including the United States (but in no less than three different countries). &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;For temporary defensive purposes, the Fund may deviate very substantially from the allocation described above.&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 utilize derivative instruments as a significant part of its strategy.&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;When consistent with the Fund&#x2019;s investment objective, the Fund&#x2019;s investments may include short-term investments, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;such as cash and cash equivalents, U.S. Government and agency securities, money market funds (including funds that &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;may be affiliated with or sponsored or managed by BlackRock), commercial paper, certificates of deposit and other &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;bank deposits and bankers&#x2019; acceptances.&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;Equity instruments consist of:&lt;/span&gt;&lt;/div&gt;  &lt;div&gt; &lt;div style="clear: both; margin-top: 4.805pt; position: relative; width: 100%;"&gt; &lt;div style="float: left; line-height: 9.87pt; text-align: left; width: 8pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 8.37pt; position: relative; top: -0.5pt;"&gt;&#x25fc;&lt;/span&gt;&lt;/div&gt; &lt;div style="float: left; line-height: 10.80pt; margin-left: 4pt; text-align: left; width: 505.00pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Common stock&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&gt; &lt;div style="clear: both; margin-top: 4.805pt; position: relative; width: 100%;"&gt; &lt;div style="float: left; line-height: 9.87pt; text-align: left; width: 8pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 8.37pt; position: relative; top: -0.5pt;"&gt;&#x25fc;&lt;/span&gt;&lt;/div&gt; &lt;div style="float: left; line-height: 10.80pt; margin-left: 4pt; text-align: left; width: 505.00pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Depositary receipts&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&gt; &lt;div style="clear: both; margin-top: 4.805pt; position: relative; width: 100%;"&gt; &lt;div style="float: left; line-height: 9.87pt; text-align: left; width: 8pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 8.37pt; position: relative; top: -0.5pt;"&gt;&#x25fc;&lt;/span&gt;&lt;/div&gt; &lt;div style="float: left; line-height: 10.80pt; margin-left: 4pt; text-align: left; width: 505.00pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;Derivative securities or instruments such as futures, options, forward contracts and swaps (including, but not &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;limited to, total return swaps, some of which may be referred to as contracts for difference), the value of which is &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;based on a common stock or group of common stocks.

This strategy can have the effect of reducing returns and minimizing opportunities for gain.&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 correlation between &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the change in market value of the instruments held by the Fund and the price of the futures contract or option; &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;(b) the possible lack of a liquid secondary market for a futures contract and the resulting inability to close a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;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;/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;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. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;income tax treatment of swap agreements is unsettled and may be subject to future legislation, regulation or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;administrative pronouncements issued by the Internal Revenue Service. If future guidance limits the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;ability to use derivatives, the Fund may have to find other ways of achieving its investment objective. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expects to settle or close out swap positions from time to time so that the value of any &#x201c;in-the-money&#x201d; swap &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;positions with a single counterparty (and other securities issued by that counterparty) will not exceed 5% of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;value of the Fund&#x2019;s total assets. While this is intended to limit counterparty risk, it may also result in the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;realizing income sooner, and/or realizing more income taxable at ordinary income tax rates, potentially causing &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shareholders to pay more in taxes and/or pay taxes sooner than would otherwise be the case.&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;To the extent derivatives are utilized to implement the Fund&#x2019;s investment strategies, the transactions may involve &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the risks described below with respect to investments in equity securities and short sales of securities.&lt;/span&gt; &lt;br/&gt;&lt;/div&gt; </oef:RiskTextBlock>

Investments in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;derivatives are counted toward the Fund&#x2019;s 80% policy to the extent that they provide investment exposure to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;securities included within that policy or to one or more market risk factors associated with such securities. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;determines that an investment is tied economically to a developed market if such investment satisfies one or more of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the following conditions: 1) the issuer&#x2019;s primary trading market is in a developed market; 2) the issuer is organized &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;under the laws of, derives at least 50% of its revenue from, or has at least 50% of its assets in developed markets; 3) &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the investment is included in an index representative of developed markets; and 4) the investment is exposed to the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;economic risks and returns of developed markets. The Fund may invest in securities of issuers of any market &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;capitalization and in securities denominated in either U.S. dollars or foreign currencies.&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: 6pt;"&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;The Fund intends to be market-neutral, which means that the Fund seeks to produce returns that have a low &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;correlation to the returns of the equity markets in which the Fund invests. The Fund pursues this market-neutral &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;strategy by taking both long and short positions in a variety of developed market equity instruments. The Fund expects &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;to maintain long and short positions primarily through the use of swap agreements and other derivative instruments, &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;such as futures, and may invest in such instruments without limitation. Although the Fund intends to maintain an &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;overall long position in its portfolio investments, the Fund generally expects to maintain significant short positions in &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;equity securities and equity-related instruments. In certain circumstances, these short positions may approach or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;reach the size of the overall long position. A long position arises where the Fund holds a security in its portfolio or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;maintains a position through a derivative instrument that provides economic exposure similar to direct ownership of &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the security. The Fund will have a short position where it sells a security it does not own by delivery of a borrowed &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;security or has entered into a derivative instrument that provides economic exposure similar to a short sale of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;security. The Fund looks to identify overvalued, undervalued or mispriced stocks and other equity instruments through &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;proprietary ranking techniques.

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;/div&gt;  &lt;div style="margin-top: 6pt;"&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: 6pt;"&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;Forward Foreign Currency Exchange Contracts&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt; font-style: italic;"&gt;&#x2014;&lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt; 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;  &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 correlation between &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the change in market value of the instruments held by the Fund and the price of the futures contract or option; &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;(b) the possible lack of a liquid secondary market for a futures contract and the resulting inability to close a &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;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. The &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;income tax treatment of swap agreements is unsettled and may be subject to future legislation, regulation or &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;administrative pronouncements issued by the Internal Revenue Service. If future guidance limits the Fund&#x2019;s &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;ability to use derivatives, the Fund may have to find other ways of achieving its investment objective. The Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;expects to settle or close out swap positions from time to time so that the value of any &#x201c;in-the-money&#x201d; swap &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;positions with a single counterparty (and other securities issued by that counterparty) will not exceed 5% of the &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;value of the Fund&#x2019;s total assets. While this is intended to limit counterparty risk, it may also result in the Fund &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;realizing income sooner, and/or realizing more income taxable at ordinary income tax rates, potentially causing &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;shareholders to pay more in taxes and/or pay taxes sooner than would otherwise be the case.&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;To the extent derivatives are utilized to implement the Fund&#x2019;s investment strategies, the transactions may involve &lt;/span&gt;&lt;span style="color: #000000; font-family: arial; font-size: 9.30pt;"&gt;the risks described below with respect to investments in equity securities and short sales of securities.&lt;/span&gt; &lt;br/&gt;&lt;/div&gt; </oef:RiskTextBlock>

Class K Shares commenced operations on March 28, 2016. As a result, the returns shown below for Class K Shares prior to March 28, 2016 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 would differ only to the extent that Class K Shares and Institutional Shares have different expenses. The actual returns of Class K Shares would have been higher than those of Institutional Shares because Class K Shares have lower expenses than Institutional Shares. The table compares the Fund&#x2019;s performance to that of the MSCI World Index (Net) and the ICE BofA 3-Month U.S. Treasury Bill Index. The ICE BofA 3-Month U.S. Treasury Bill Index is relevant to the Fund because it has characteristics similar to the Fund&#x2019;s investment strategies. 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. 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>

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.
