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 Commodity Strategies Fund (USD $)	1 Year	3 Years	5 Years	10 Years
Investor A Shares	671	1,092	1,539	2,775
Investor C Shares	329	829	1,456	3,143
Institutional Shares	133	536	963	2,155

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

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
BlackRock Commodity Strategies Fund Investor C Shares	229	829	1,456	3,143

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 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 period October 3, 2011 (commencement of operations) through July 31, 2012, the Fund’s portfolio turnover rate was 127% of the average value of its portfolio.

Principal Investment Strategies of the Fund

The Fund utilizes two strategies and under normal circumstances expects to invest approximately 50% of its total assets in each strategy; provided, however, that from time to time, Fund management may alter the weightings if it deems it prudent to do so based on market conditions, trends or movements or other similar factors.

One strategy focuses on investments in commodity-linked derivatives. To meet coverage and collateral requirements associated with these derivative investments, and to invest excess cash, the Fund holds a portion of its portfolio in investment-grade short-term fixed income securities. The other strategy focuses on equity investments in commodity-related companies, including, but not limited to, companies operating in the mining, energy and agricultural sectors. The Fund invests in equity securities of such companies in order to complement the commodity exposures achieved through investments in commodity-linked derivatives. Taken together, these two strategies offer broad exposure to global commodities market trends across asset classes, industries, sectors, and regions.

Commodities are assets that have tangible properties, such as oil and other energy products, metals, and agricultural products. Commodity-linked derivative instruments include, but are not limited to, commodity-linked notes, swap agreements, commodity options, futures and options on futures, that provide exposure to the investment returns of the commodities markets, without investing directly in physical commodities.

Commodity-related companies include, but are not limited to, companies in commodities, natural resources and energy businesses and in associated businesses and companies that provide services or have exposure to such businesses (collectively, the “Commodities Sector”). These companies include, without limitation, companies engaged in the exploration, ownership, production, refinement, processing, transportation, distribution or marketing of commodities, companies that use commodities extensively in their products and companies that provide technology and services to commodity-related companies. This includes companies that are engaged in businesses such as integrated oil, oil and gas exploration and production, energy services and technology, chemicals and oil products, coal and other consumable fuel, gold and precious metals, metals and minerals, forest products, agricultural chemicals and services, farm land, alternative energy sources, environmental services and agricultural products (including crop growers, owners of plantations, and companies that produce and process foods), as well as related transportation companies, equipment manufacturers, service providers and engineering, procurement and construction (“EPC”) companies.

The Fund may make investments directly or through investments in BlackRock Cayman Commodity Strategies Fund, Ltd. (the “Subsidiary”), a wholly-owned subsidiary of the Fund formed in the Cayman Islands. The Subsidiary is managed by BlackRock and has the same investment objective as the Fund. The assets of the Subsidiary are subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as the Fund, except that the Subsidiary does not invest in equity securities of commodity-related companies, and may invest without limitation in commodity-linked derivative instruments. The Fund will not invest more than 25% of its total assets (measured at the time of investment) in the Subsidiary.

The Fund manages the term structure of its commodity-linked derivative positions and has the flexibility to gain exposure to futures maturities which differ from those in the Fund’s benchmark, the Dow Jones-UBS Commodity Index Total Return^SM. This is done in an effort to achieve efficient investment results and minimize any adverse effects on returns caused by commodity term structures.

Equity securities held by the Fund may include common stocks, preferred stocks, convertible securities, warrants, depositary receipts, and other instruments whose price is linked to the value of common stock, and equity interests in master limited partnerships. In addition, the Fund may also invest in fixed income instruments (of any credit quality and any duration) of commodity-related companies.

There are no restrictions on investment in terms of geography or market capitalization. As such, the Fund may invest in both U.S. and non-U.S. companies, including companies located in emerging markets, and in securities denominated in both U.S. dollars and foreign currencies.

Principal Risks of Investing in the Fund

Risk is inherent in all investing. The value of your investment in Commodity Strategies 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 certain risks of investing in the Fund.

• Commodities Investment Risk — Investing in commodity-linked derivative instruments and equity securities of commodity-related companies may subject the Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in the Fund’s holdings.

The commodities markets may fluctuate widely based on a variety of factors. Movements in commodity investment prices are outside of the Fund’s control and may not be anticipated by Fund management. Price movements may be influenced by, among other things: governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; changing market and economic conditions; market liquidity; weather and climate conditions; changing supply and demand relationships and levels of domestic production and imported commodities; the availability of local, intrastate and interstate transportation systems; energy conservation; the success of exploration projects; changes in international balances of payments and trade; domestic and foreign rates of inflation; currency devaluations and revaluations; domestic and foreign political and economic events; domestic and foreign interest rates and/or investor expectations concerning interest rates; foreign currency/exchange rates; domestic and foreign governmental regulation and taxation; war, acts of terrorism and other political upheaval and conflicts; governmental expropriation; investment and trading activities of mutual funds, hedge funds and commodities funds; changes in philosophies and emotions of market participants. The frequency and magnitude of such changes cannot be predicted.

The commodity markets are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions. U.S. futures exchanges and some foreign exchanges limit the amount of fluctuation in futures contract prices which may occur in a single business day (generally referred to as “daily price fluctuation limits”). The maximum or minimum price of a contract as a result of these limits is referred to as a “limit price.” If the limit price has been reached in a particular contract, no trades may be made beyond the limit price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices.

• Commodities Regulatory Risk — Commodity-related companies are subject to significant federal, state and local government regulation in virtually every aspect of their operations, including how facilities are constructed, maintained and operated, environmental and safety controls, and the prices they may charge for the products and services they provide. The U.S. Commodity Futures Trading Commission (the “CFTC”) and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily limits and the suspension of trading. Any of these actions, if taken, could adversely affect the returns of the Fund by limiting or precluding investment decisions the Fund might otherwise make. In addition, various national governments have expressed concern regarding the derivatives markets and the need to regulate such markets. Stricter laws, regulations or enforcement policies, with respect to the derivatives market, could be enacted in the future which would likely increase compliance costs and may adversely affect the operations and financial performance of commodity-related companies. The effect of any future regulatory change on the Fund is impossible to predict, but could be substantial and adverse to the Fund. Also, future regulatory developments may impact the Fund’s ability to invest in commodity-linked derivatives. In addition, the Internal Revenue Service (the “IRS”) has currently suspended the issuance of private letter rulings relating to the tax treatment of income and gain generated by investments in commodity-linked notes and income generated by investments in controlled foreign corporations, such as the Subsidiary, that invest in commodity-linked derivative instruments. See “— Tax and Regulatory Risk” below.

• Credit Risk — Credit risk refers to the possibility that the issuer of a security will not be able to make payments of interest and principal when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer.

• Derivatives Risk — The Fund’s use of derivatives may reduce the Fund’s returns and/or increase volatility. Volatility is defined as the characteristic of a security, an index or a market to fluctuate significantly in price within a short time period. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities or commodities markets. 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. Derivatives may give rise to a form of leverage and may expose the Fund to greater risk and increase its costs. Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet known and may not be known for some time. New regulation may make derivatives more costly, may limit the availability of derivatives, or may otherwise adversely affect the value or performance of derivatives.

Risks Specific to Certain Derivatives Used by the Fund

Commodity-Linked Derivatives — The value of a commodity-linked derivative investment typically is based upon the price movements of a commodity, a commodity futures contract or commodity index, or some other readily measurable economic variable. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, volatility of the underlying benchmark, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments. The value of commodity-linked derivatives will rise or fall in response to changes in the underlying commodity or related index. Investments in commodity-linked derivatives may be subject to greater volatility than non-derivative based investments. A highly liquid secondary market may not exist for certain commodity-linked derivatives, and there can be no assurance that one will develop.

Commodity-linked derivatives also may be subject to credit and interest rate risks that in general affect the values of fixed income securities. Therefore, at maturity, the Fund may receive more or less principal than it originally invested. The Fund might receive interest payments that are more or less than the stated coupon interest payments.

In connection with the Fund’s direct and indirect investments in commodity-linked derivatives, the Fund will attempt to manage its counterparty exposure so as to limit its exposure to any one counterparty. However, due to the limited number of entities that may serve as counterparties (and which the Fund believes are creditworthy) at any one time the Fund may enter into swap agreements with a limited number of counterparties and may invest in commodity-linked notes issued by a limited number of issuers that will act as counterparties, which may increase the Fund’s exposure to counterparty credit risk. There can be no assurance that the Fund will be able to limit exposure to any one counterparty at all times.

Commodity-Linked Notes — Commodity-linked notes involve substantial risks, including the risk of loss of a significant portion of their principal value. In addition to commodity risk and general derivatives risk, they may be subject to additional special risks, such as risk of loss of interest and principal, lack of secondary market and risk of greater volatility, that do not affect traditional equity and debt securities.

Swaps — 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.

Forward Foreign Currency Exchange Contracts — 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.

• Emerging Markets Risk — Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets.

• 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.

• Interest Rate Risk — Interest rate risk is the risk that prices of bonds and other fixed income securities will increase as interest rates fall and decrease as interest rates rise.

• 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.

• Non-Diversification Risk — The Fund is a non-diversified fund. Because the Fund may invest in securities of a smaller number of issuers, it may be more exposed to the risks associated with and developments affecting an individual issuer than a fund that invests more widely.

• Precious Metals and Related Securities Risk — Prices of precious metals and of precious metal related securities historically have been very volatile. The high volatility of precious metal prices may adversely affect the financial condition of companies involved with precious metals. The production and sale of precious metals by governments or central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals. Other factors that may affect the prices of precious metals and securities related to them include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals.

• Sector Risk — Sector risk is the risk that the Fund’s concentration in the securities of companies in a specific market sector or industry will cause the Fund to be more exposed to the price movements of companies in and developments affecting that sector than a more broadly diversified fund. The Fund’s investments will be concentrated in a group of industries that make up the Commodities Sector. Because the Fund is focused in specific industries, it may present more risks than if it were broadly diversified over numerous industries and sectors of the economy.

• Small Cap and Emerging Growth Securities Risks — Small cap or emerging growth companies may have limited product lines or markets. They may be less financially secure than larger, more established companies. They may depend on a more limited management group than larger capitalized companies.

• Subsidiary Risk — By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the Investment Company Act of 1940, as amended (the “Investment Company Act”), and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the Investment Company Act. However, the Fund wholly owns and controls the Subsidiary, and the Fund and the Subsidiary are both managed by BlackRock, making it unlikely that the Subsidiary will take action contrary to the interests of the Fund and its shareholders. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the SAI and could adversely affect the Fund.

• Tax and Regulatory Risk — Certain aspects of the tax treatment of derivative instruments, including 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. Other future regulatory developments may also impact the Fund’s ability to invest or remain invested in certain derivatives.

In addition, the Fund has requested a private letter ruling from the IRS concluding that the income and gain generated by its investments in commodity-linked notes, and the income generated from its investment in the Subsidiary, which invests in commodity-linked derivative instruments, would be “qualifying income” for regulated investment company qualification purposes. However, in late July 2011, the IRS indicated that the granting of private letter rulings like the one requested by the Fund is currently suspended. As a result, there can be no assurance that the IRS will grant the private letter ruling requested by the Fund. If the IRS makes an adverse determination relating to the treatment of such income and gain, the Fund would likely need to significantly change its investment strategies, which could adversely affect the Fund.

Performance Information

Because the Fund does not have a full calendar year of operations, it does not have performance information an investor would find useful in evaluating the risks of investing in the Fund. The Fund’s benchmark is the Dow Jones-UBS Commodity Index Total Return^SM.

[1] A contingent deferred sales charge ("CDSC") of 1.00% is assessed on certain redemptions of Investor A Shares made within 18 months after purchase where no initial sales charge was paid at time of purchase as part of an investment of $1,000,000 or more.

[2] There is no CDSC on Investor C Shares after one year.

[1] The Total Annual Fund Operating Expenses do not correlate to the ratios of expenses to average net assets given in the Fund's annual report, which do not include Acquired Fund Fees and Expenses.

[2] As described in the "Management of the Fund" section of the Fund's prospectus on pages 39-43, BlackRock has contractually agreed to waive and/or reimburse fees or expenses in order to limit Total Annual Fund Operating Expenses After Fee Waivers and/or Expense Reimbursements (excluding Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses) as a percentage of average daily net assets to 1.50% (for Investor A Shares), 2.25% (for Investor C Shares) and 1.30% (for Institutional Shares) until December 1, 2013. The Fund may have to repay some of these waivers and reimbursements to BlackRock in the following two years. The agreement may be terminated upon 90 days' notice by a majority of the non-interested trustees of the Trust or by a vote of a majority of the outstanding voting securities of the Fund.
