Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - BlackRock Global Long/Short Equity Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Investor A Shares	726	1,145	1,590	2,819
Investor C Shares	389	886	1,508	3,185
Institutional Shares	186	576	990	2,148

You would pay the following expenses if you did not redeem your shares:

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
BlackRock Global Long/Short Equity Fund | Investor C Shares | USD ($)	289	886	1,508	3,185

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when 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. For the fiscal year ended July 31, 2015, the Fund’s portfolio turnover rate was 17% of the average value of its portfolio.

Principal Investment Strategies of the Fund

Under normal circumstances, Global Long/Short Equity Fund invests at least 80% of its total assets in equity instruments and related derivative instruments issued by, or tied economically to, companies located in developed markets. 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’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.

The Fund pursues its investment objective by taking both long and short positions in a variety of developed market equity instruments. The Fund expects to maintain long and short positions primarily through the use of swap agreements and other derivative instruments, such as futures, and may invest in such instruments without limitation. Although the Fund intends to maintain an overall long position in its portfolio investments, the Fund generally expects to maintain significant short positions in equity securities and equity-related instruments. In certain circumstances, these short positions may approach or reach the size of the overall long position. The use of both long and short positions better enables the Fund to seek to produce returns that have low correlation to those available by investing in the market as a whole. A long position arises where the Fund holds a security in its portfolio or maintains a position through a derivative instrument that provides economic exposure similar to direct ownership of the security. The Fund will have a short position where it sells a security it does not own by delivery of a borrowed security or has entered into a derivative instrument that provides economic exposure similar to a short sale of the security. The Fund looks to identify overvalued, undervalued or mispriced stocks and other equity instruments through proprietary ranking techniques. The Fund takes long positions primarily in securities that BlackRock has identified as attractive and short positions in such securities that BlackRock has identified as overvalued or poised for underperformance.

Under normal circumstances, the Fund anticipates it will allocate a substantial amount (approximately 40% or more — unless market conditions are not deemed favorable by BlackRock, in which case the Fund would invest at least 30%) of its total assets in securities (or derivatives with similar economic characteristics) of (i) foreign government issuers, (ii) issuers organized or located outside the United States, (iii) issuers whose securities primarily trade in a market located outside the United States, or (iv) issuers doing a substantial amount of business outside the United States, which the Fund considers to be companies that derive at least 50% of their revenue or profits from business outside the United States or have at least 50% of their sales or assets outside the United States. The Fund will allocate its assets among various regions and countries, including the United States (but in no less than three different countries). For temporary defensive purposes the Fund may deviate very substantially from the allocation described above.

The Fund may utilize derivative instruments as a significant part of its strategy.

When consistent with the Fund’s investment objective, the Fund’s investments may include short-term investments such as cash and cash equivalents, U.S. Government and agency securities, money market funds (including funds that may be affiliated with or sponsored or managed by BlackRock), commercial paper, certificates of deposit and other bank deposits and bankers’ acceptances.

Equity instruments consist of:

• Common stock

• Depositary receipts

• Derivative securities or instruments such as futures, options, contracts for difference, forward contracts and swaps (including, among other swaps, total return swaps), the value of which is based on a common stock or group of common stocks. A contract for difference offers exposure to price changes in an underlying security without ownership of such security, typically by providing investors the ability to trade on margin.

The Fund may engage in active and frequent trading of portfolio securities to achieve its primary investment strategies.

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of principal risks of investing in the Fund.

• Depositary Receipts Risk — The issuers of unsponsored depositary receipts are not obligated to disclose information that is, in the United States, considered material. Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts. Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted.

• Derivatives Risk — The Fund’s use of derivatives may increase its costs, reduce the Fund’s returns and/or increase volatility. Derivatives involve significant risks, including:
  
  Volatility Risk — Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate with the overall securities markets.
  
  Counterparty Risk — Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation.
  
  Market and Liquidity Risk — The possible lack of a liquid secondary market for derivatives and the resulting inability of the Fund to sell or otherwise close a derivatives position could expose the Fund to losses and could make derivatives more difficult for the Fund to value accurately.
  
  Valuation Risk — Valuation may be more difficult in times of market turmoil since many investors and market makers may be reluctant to purchase complex instruments or quote prices for them.
  
  Leverage Risk — Certain transactions in derivatives involve substantial leverage risk and may expose the Fund to potential losses that exceed the amount originally invested by the Fund.
  
  Regulatory Risk — Derivative contracts, including, without limitation, swaps, currency forwards and non-deliverable forwards, are subject to regulation under the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) in the United States and under comparable regimes in Europe, Asia and other non-U.S. jurisdictions. Under the Dodd-Frank Act, certain derivatives may become subject to margin requirements when regulations are finalized. Implementation of such regulations under the Dodd-Frank Act regarding clearing, mandatory trading and margining of swaps and other derivatives may increase the costs to the Fund of trading in these instruments and, as a result, may affect returns to investors in the Fund. Certain aspects of the tax treatment of derivative instruments, including swap agreements and commodity-linked derivative instruments, are currently unclear and may be affected by changes in legislation, regulations or other legally binding authority that could affect the character, timing and amount of the Fund’s taxable income or gains and distributions.
  
  Risks Specific to Certain Derivatives Used by the Fund

  Forward Foreign Currency Exchange Contracts — Forward foreign currency exchange transactions are over-the-counter contracts to purchase or sell a specified amount of a specified currency or multinational currency unit at a price and future date set at the time of the contract. Forward foreign currency exchange contracts do not eliminate fluctuations in the value of non-U.S. securities but rather allow the Fund to establish a fixed rate of exchange for a future point in time. This strategy can have the effect of reducing returns and minimizing opportunities for gain.
  
  Futures — Futures are standardized, exchange-traded contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of an asset at a specified future date at a specified price. The primary risks associated with the use of futures contracts and options are: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract or option; (b) the possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the investment advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; and (e) the possibility that the counterparty will default in the performance of its obligations.
  
  Swaps — Swap agreements are two-party contracts entered into for periods ranging from a few weeks to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which can be adjusted for an interest factor. Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund and the risk that the Fund will not be able to meet its obligations to pay the other party to the agreement.
  
  Contracts for Difference — Contracts for difference are subject to liquidity risk because the liquidity of contracts for difference is based on the liquidity of the underlying instrument, and are subject to counterparty risk, i.e., the risk that the counterparty to the contracts for difference transaction may be unable or unwilling to make payments or to otherwise honor its financial obligations under the terms of the contract. To the extent that there is an imperfect correlation between the return on the Fund’s obligation to its counterparty under the contract for difference and the return on related assets in its portfolio, the contracts for difference transaction may increase the Fund’s financial risk. Contracts for difference, like many other derivative instruments, involve the risk that, if the derivative security declines in value, additional margin would be required to maintain the margin level. The seller may require the Fund to deposit additional sums to cover this, and this may be at short notice. If additional margin is not provided in time, the seller may liquidate the positions at a loss for which the Fund is liable. Contracts for difference are not registered with the Securities and Exchange Commission or any U.S. regulator, and are not subject to U.S. regulation.

  To the extent derivatives are utilized to implement the Fund’s investment strategies, the transactions may involve the risks described below with respect to investments in equity securities and short sales of securities.

• Equity Securities Risk — Stock markets are volatile. The price of equity securities fluctuates based on changes in a company’s financial condition and overall market and economic conditions.

• Foreign Securities Risk — Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:

• The Fund generally holds its foreign securities and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.

• Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio.

• The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.

• The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries.

• Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.

• Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.

• The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns in, or rising government debt levels of, several European countries. These events may spread to other countries in Europe. These events may affect the value and liquidity of certain of the Fund’s investments.

• High Portfolio Turnover Risk — The Fund may engage in active and frequent trading of its portfolio securities. High portfolio turnover (more than 100%) may result in increased transaction costs to the Fund, including brokerage commissions, dealer mark-ups and other transaction costs on the sale of the securities and on reinvestment in other securities. The sale of Fund portfolio securities may result in the realization and/or distribution to shareholders of higher capital gains or losses as compared to a fund with less active trading policies. Given the frequency of sales, such gain or loss will likely be short-term capital gain or loss and would increase an investor’s tax liability unless shares are held through a tax-deferred or exempt vehicle. These effects of higher than normal portfolio turnover may adversely affect Fund performance.

• Leverage Risk — Some transactions may give rise to a form of economic leverage. These transactions may include, among others, derivatives, and may expose the Fund to greater risk and increase its costs. The use of leverage may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet any required asset segregation requirements. Increases and decreases in the value of the Fund’s portfolio will be magnified when the Fund uses leverage.

• Market Risk and Selection Risk — Market risk is the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. Selection risk is the risk that the securities selected by Fund management will underperform the markets, the relevant indices or the securities selected by other funds with similar investment objectives and investment strategies. This means you may lose money.

• Mid Cap Securities Risk — The securities of mid cap companies generally trade in lower volumes and are generally subject to greater and less predictable price changes than the securities of larger capitalization companies.

• Money Market Securities Risk — If market conditions improve while the Fund has invested some or all of its assets in high quality money market securities, this strategy could result in reducing the potential gain from the market upswing, thus reducing the Fund’s opportunity to achieve its investment objective.

• Short Sales Risk — Because making short sales in securities that it does not own exposes the Fund to the risks associated with those securities, such short sales involve speculative exposure risk. The Fund may incur a loss as a result of a short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the security sold short. Short sale transactions involve leverage because they can provide investment exposure in an amount exceeding the initial investment.

Performance Information

The information shows you how the Fund’s performance has varied for the periods since inception and provides some indication of the risks of investing in the Fund. The table compares the Fund’s performance to that of the BofA Merrill Lynch 3-Month U.S. Treasury Bill Index.
