As described in the “Management of the Fund” section of the Fund’s prospectus beginning on page 27, BlackRock Advisors, LLC (“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 0.55% (for Investor A Shares), 1.30% (for Investor B and Investor C Shares) and 0.20% (for Institutional Shares) through July 31, 2018. The Fund may have to repay some of these waivers and/or 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.

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:

	1 Year	3 Years	5 Years	10 Years
Investor A Shares ¹	$ 56	$267	$495	$1,151
Investor B Shares ¹	$132	$484	$860	$1,736 ² /$1,652 ³ /$1,915 ⁴
Investor C Shares ¹	$132	$480	$851	$1,895
Institutional Shares	$ 20	$143	$277	$ 667

¹	These expense figures do not reflect the imposition of the deferred sales charge which may be deducted upon the redemption of Investor A, Investor B or Investor C Shares of the Fund received in an exchange transaction for Investor A, Investor B or Investor C Shares of a non-money market fund advised by BlackRock or its affiliates (each, a “Non-Money Market BlackRock Fund”) as described in the applicable prospectuses. No deferred sales charge is deducted upon the redemption of Investor A, Investor B or Investor C Shares of the Fund that are purchased from the Trust and not acquired by exchange.
²	Based on the conversion of Investor B Shares to Investor A Shares after eight years (applies to shares received in an exchange transaction for Investor B Shares of certain equity Non-Money Market BlackRock Funds).
³	Based on the conversion of Investor B Shares to Investor A Shares after seven years (applies to shares received in an exchange transaction for Investor B Shares of certain fixed-income Non-Money Market BlackRock Funds).
⁴	Based on the conversion of Investor B Shares to Investor A Shares after ten years (applies to shares received in an exchange transaction for Investor B Shares of certain fixed-income Non-Money Market BlackRock Funds).

Principal Investment Strategies of the Fund

The Fund seeks to achieve its investment objective by investing in a broad range of short-term, high quality U.S. dollar-denominated money market instruments, including government, U.S. and foreign bank, commercial and other obligations. The Fund invests in securities maturing in 397 days or less (with certain exceptions), and the portfolio will have a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. Under normal market conditions, at least 25% of the Fund’s total assets will be invested in obligations of issuers in the financial services industry or in obligations, such as repurchase agreements, secured by such obligations.

The Fund may purchase variable and floating rate notes, which are instruments that provide for adjustments in the interest rate on certain reset dates or whenever a specified interest rate index changes, respectively. The Fund may transact in securities on a when-issued, delayed delivery or forward commitment basis.

The Fund seeks to maintain a net asset value (“NAV”) of $1.00 per share.

The securities purchased by the Fund are subject to the quality, diversification and other requirements of Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), and other rules of the Securities and Exchange Commission. The Fund will only purchase securities that present minimal credit risk as determined by BlackRock, the Fund’s investment manager, pursuant to guidelines approved by the Trust’s Board of Trustees (the “Board”).

Principal Risks of Investing in the Fund

Risk is inherent in all investing. You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

The following is a summary description of principal risks of investing in the Fund.

■

Asset-Backed Securities Risk — Asset-backed securities represent interests in “pools” of assets, including consumer loans or receivables held in trust. Asset-backed securities are subject to credit, interest rate, prepayment and extension risks. These securities also are subject to risk of default on the underlying asset, particularly during periods of economic downturn.

■

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.

■	Extension Risk — When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.

■

Financial Services Industry Risk — Because of its concentration in the financial services industry, the Fund will be more susceptible to any economic, business, political or other developments which generally affect this industry sector. As a result, the Fund will be exposed to a large extent to the risks associated with that industry, such as government regulation, the availability and cost of capital funds, consolidation and general economic conditions. Financial services companies are also exposed to losses if borrowers and other counterparties experience financial problems and/or cannot repay their obligations.

When interest rates go up, the value of securities issued by many types of financial services companies generally goes down. In many countries, financial services and the companies that provide them are regulated by governmental entities, which can increase costs for new services or products and make it difficult to pass increased costs on to consumers. In certain areas, deregulation of financial services companies has resulted in increased competition and reduced profitability for certain companies.

The profitability of many types of financial services companies may be adversely affected in certain market cycles, including periods of rising interest rates, which may restrict the availability and increase the cost of capital, and declining economic conditions, which may cause credit losses due to financial difficulties of borrowers. Because many types of financial services companies are vulnerable to these economic cycles, a large portion of the Fund’s investments may lose value during such periods.

Table of Contents

■	Foreign Exposure Risk — Securities issued or supported by foreign entities, including foreign banks and corporations, may involve additional risks and considerations. Extensive public information about the foreign issuer may not be available, and unfavorable political, economic or governmental developments in the foreign country involved could affect the payment of principal and interest.
■	Income Risk — Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates.
■	Interest Rate Risk — Interest rate risk is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter-term securities. Due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund.
■	Liquidity Fee and Redemption Gate Risk — The Board has discretion to impose a liquidity fee of up to 2% upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. Accordingly, you may not be able to sell your shares or your redemptions may be subject to a liquidity fee when you sell your shares at certain times.
■	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.
■	Prepayment Risk — When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.
■	Repurchase Agreements and Purchase and Sale Contracts Risk — If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the Fund may lose money.
■	Stable Net Asset Value Risk — The Fund may not be able to maintain a stable NAV of $1.00 per share at all times. If the Fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), the Fund, along with other money market funds, could be subject to increased redemption activity.
■	U.S. Government Obligations Risk — Certain securities in which the Fund may invest, including securities issued by certain U.S. Government agencies and U.S. Government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States.
■	Variable and Floating Rate Instrument Risk — The absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults.
■	When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Performance Information

The information shows you how the Fund’s performance has varied year by year and provides some indication of the risks of investing in the Fund. 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 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’s returns would have been lower. The Fund is a money market fund managed pursuant to the requirements of Rule 2a-7 under the Investment Company Act. Effective May 28, 2010, Rule 2a-7 was amended to impose new liquidity, credit quality and maturity requirements on all money market funds. Fund performance shown prior to May 28, 2010 is based on Investment Company Act rules then in effect and is not an indication of future returns. Updated information on the Fund’s performance can be obtained by phone at (800) 882-0052.

Details About the Fund

Included in this prospectus are sections that tell you about buying and selling shares, management information, shareholder features of BlackRock Money Market Portfolio (“Money Market Portfolio” or the “Fund”), a series of BlackRock Funds ^SM (the “Trust”), and your rights as a shareholder.

How the Fund Invests

The Fund is a retail money market fund managed pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

■	The Fund seeks to maintain a net asset value (“NAV”) of $1.00 per share.
■	The Fund will maintain a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. For a discussion of dollar-weighted average maturity and dollar-weighted average life, please see the Glossary on page 38.
■	Pursuant to Rule 2a-7, the Fund is subject to a “general liquidity requirement” that requires that the Fund hold securities that are sufficiently liquid to meet reasonably foreseeable shareholder redemptions in light of its obligations under Section 22(e) of the Investment Company Act regarding share redemptions and any commitments the Fund has made to shareholders. To comply with this general liquidity requirement, BlackRock Advisors, LLC (“BlackRock”) must consider factors that could affect the Fund’s liquidity needs, including characteristics of the Fund’s investors and their likely redemptions. Depending upon the volatility of its cash flows (particularly shareholder redemptions), this may require the Fund to maintain greater liquidity than would be required by the weekly minimum liquidity requirement discussed below.
■	The Fund will not acquire any illiquid security (i.e., securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund) if, immediately following such purchase, more than 5% of the Fund’s total assets are invested in illiquid securities. The Fund will not acquire any security other than a daily liquid asset unless, immediately following such purchase, at least 10% of its total assets would be invested in daily liquid assets, and the Fund will not acquire any security other than a weekly liquid asset unless, immediately following such purchase, at least 30% of its total assets would be invested in weekly liquid assets. For a discussion of daily liquid assets and weekly liquid assets, please see the Glossary on page 38.
■	The Fund invests in securities maturing within 13 months or less from the date of purchase, with certain exceptions. For example, certain government securities held by the Fund may have remaining maturities exceeding 13 months if such securities provide for adjustments in their interest rates not less frequently than every 13 months.
■	The securities purchased by the Fund are subject to the quality, diversification, and other requirements of Rule 2a-7, and other rules of the Securities and Exchange Commission (the “SEC”). The Fund will purchase securities (or issuers of such securities) that are Eligible Securities that present minimal credit risk as determined by BlackRock pursuant to guidelines approved by the Trust’s Board of Trustees (the “Board”). For a discussion of Eligible Securities, please see the Glossary on page 38.

The Board will be permitted to impose a liquidity fee on redemptions from the Fund (up to 2%) or temporarily restrict redemptions from the Fund for up to 10 business days during a 90 day period under certain circumstances. Please see the section below titled “Account Information — Liquidity Fees and Redemption Gates” for additional information about liquidity fees and redemption gates.

Investment Objective

The investment objective of the Fund is to seek as high a level of current income as is consistent with maintaining liquidity and stability of principal.

Should the Board determine that the investment objective of the Fund should be changed, shareholders will be given at least 30 days’ notice before any such change is made. However, such change can be effected without shareholder approval.

Table of Contents

Principal Investment Strategies

The Fund invests in a broad range of short-term, high quality U.S. dollar-denominated money market instruments, including government, U.S. and foreign bank, commercial and other obligations. The Fund invests in securities maturing in 397 days or less (with certain exceptions), and the portfolio will have a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. Under normal market conditions, at least 25% of the Fund’s total assets will be invested in obligations of issuers in the financial services industry or in obligations, such as repurchase agreements, secured by such obligations. Specifically, the Fund may invest in:

■	U.S. dollar-denominated obligations issued or supported by the credit of U.S. or foreign banks or savings institutions with total assets of more than $1 billion (including obligations of foreign branches of such banks)

■

High quality commercial paper and other obligations issued or guaranteed by U.S. and foreign corporations and other issuers rated (at the time of purchase) A-2 or higher by S&P Global Ratings, P-2 (Prime-2) or higher by Moody’s Investors Service, Inc. or F2 or higher by Fitch Ratings, Inc., as well as high quality corporate bonds rated A or higher at the time of purchase by those rating agencies

■	Unrated notes, paper and other instruments that are determined by Fund management to be of comparable quality to the instruments described above
■	Asset-backed securities (including interests in “pools” of assets such as mortgages, installment purchase obligations and credit card receivables)
■	Securities issued or guaranteed by the U.S. Government or by its agencies or authorities
■	Dollar-denominated securities issued or guaranteed by foreign governments or their political subdivisions, agencies or authorities
■	Repurchase agreements relating to the above instruments

Pursuant to Rule 2a-7 under the Investment Company Act, the Fund will generally limit its purchases of any one issuer’s securities (other than U.S. Government obligations and repurchase agreements collateralized by such securities) to 5% of the Fund’s total assets, except that up to 25% of its total assets may be invested in securities of one issuer for a period of up to three business days; provided that the Fund may not invest in the securities of more than one issuer in accordance with the foregoing exception at any one time.

Other Strategies

In addition to the principal strategies discussed above, the Fund may also invest or engage in the following investments/strategies:

■	Investment Company Securities — The Fund may invest in securities issued by other open-end or closed-end investment companies as permitted by the Investment Company Act. A pro rata portion of the other investment companies’ expenses may be borne by the Fund’s shareholders. These investments may include, as consistent with the Fund’s investment objective and policies, certain variable rate demand securities issued by closed-end funds, which invest primarily in portfolios of taxable or tax-exempt securities. It is anticipated that the payments made on the variable rate demand securities issued by closed-end municipal bond funds will be exempt from federal income tax.
■	Uninvested Cash Reserves — The Fund may hold up to 20% of its assets in uninvested cash reserves. Uninvested cash reserves will not earn income.
■	U.S. Treasury Floating Rate Notes — The Fund may invest in U.S. Treasury Floating Rate Notes (FRNs). These are two-year notes issued by the U.S. Treasury that reset their interest rates on a weekly basis. At maturity, the face value of an FRN is paid to the note holder.

Investment Risks

to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

The following is a description of certain risks of investing in the Fund.

Principal Risks of Investing in the Fund

■	Asset-Backed Securities Risk — Asset-backed securities represent interests in “pools” of assets, including consumer loans or receivables held in trust. Asset-backed securities, like traditional fixed-income securities, are subject to credit, interest rate, prepayment and extension risks.
	The Fund’s investments in asset-backed securities are subject to additional risks associated with the nature of the assets and the servicing of those assets. These securities also are subject to the risk of default on the underlying assets, particularly during periods of economic downturn.
	Asset-backed securities entail further risks, including the risk that, in certain states, it may be difficult to perfect the liens securing the collateral backing certain asset-backed securities. In addition, certain asset-backed securities are based on loans that are unsecured, which means that there is no collateral to seize if the underlying borrower defaults.
■	Credit Risk — Credit risk refers to the possibility that the issuer of a security will not be able to make principal and interest payments 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. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

■

Extension Risk — When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall. Rising interest rates tend to extend the duration of securities, making them more sensitive to changes in interest rates. The value of longer-term securities generally changes more in response to changes in interest rates than shorter-term securities. As a result, in a period of rising interest rates, securities may exhibit additional volatility and may lose value.

■

■	Foreign Exposure Risk — Securities issued or supported by foreign entities, including foreign banks and corporations, may involve additional risks and considerations. Extensive public information about the foreign issuer may not be available, and unfavorable political, economic or governmental developments in the foreign country involved could affect the payment of principal and interest.
■	Income Risk — The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates.
■	Interest Rate Risk — Interest rate risk is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter-term securities. Due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund.
■	Liquidity Fee and Redemption Gate Risk — The Board has discretion to impose a liquidity fee of up to 2% upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. Accordingly, you may not be able to sell your shares or your redemptions may be subject to a liquidity fee when you sell your shares at certain times.

Table of Contents

■	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.
■	Prepayment Risk — When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields. In periods of falling interest rates, the rate of prepayments tends to increase (as does price fluctuation) as borrowers are motivated to pay off debt and refinance at new lower rates. During such periods, reinvestment of the prepayment proceeds by the management team will generally be at lower rates of return than the return on the assets that were prepaid. Prepayment reduces the yield to maturity and the average life of the security.
■	Repurchase Agreements and Purchase and Sale Contracts Risk — If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the Fund may lose money.
■	Stable Net Asset Value Risk — The Fund may not be able to maintain a stable NAV of $1.00 per share at all times. If the Fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), the Fund, along with other money market funds, could be subject to increased redemption activity.
■	U.S. Government Obligations Risk — Not all U.S. Government securities are backed by the full faith and credit of the United States. Obligations of certain agencies, authorities, instrumentalities and sponsored enterprises of the U.S. Government are backed by the full faith and credit of the United States (e.g., the Government National Mortgage Association); other obligations are backed by the right of the issuer to borrow from the U.S. Treasury (e.g., the Federal Home Loan Banks) and others are supported by the discretionary authority of the U.S. Government to purchase an agency’s obligations. Still others are backed only by the credit of the agency, authority, instrumentality or sponsored enterprise issuing the obligation. No assurance can be given that the U.S. Government would provide financial support to any of these entities if it is not obligated to do so by law.
■	Variable and Floating Rate Instrument Risk — The absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults.
■	When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Other Risks of Investing in the Fund

The Fund may also be subject to certain other risks associated with its investments and investment strategies, including:

■

Expense Risk — Fund expenses are subject to a variety of factors, including fluctuations in the Fund’s net assets. Accordingly, actual expenses may be greater or less than those indicated. For example, to the extent that the Fund’s net assets decrease due to market declines or redemptions, the Fund’s expenses will increase as a percentage of Fund net assets. During periods of high market volatility, these increases in the Fund’s expense ratio could be significant.

■

Investment in Other Investment Companies Risk — As with other investments, investments in other investment companies, including ETFs, are subject to market and selection risk. In addition, if the Fund acquires shares of investment companies, including ones affiliated with the Fund, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies (to the extent not offset by BlackRock through waivers to the Fund’s management fees). To the extent the Fund is held by an affiliated fund, the ability of the Fund itself to hold other investment companies may be limited.

■	Liquidity Risk — Liquidity risk refers to the possibility that it may be difficult or impossible to sell certain positions at an acceptable price.

How to Choose the Share Class that Best Suits Your Needs

The Fund currently offers multiple share classes (Investor A and Institutional Shares in this prospectus), allowing you to invest in the way that best suits your needs. The Fund no longer offers Investor B or Investor C Shares to new investors. Each share class represents an ownership interest in the same investment portfolio of the Fund. When you choose your class of shares, you should consider the size of your investment and how long you plan to hold your shares. Either your financial professional or your selected securities dealer, broker, investment adviser, service provider or industry professional (including BlackRock, The PNC Financial Services Group, Inc. (“PNC”) and their respective affiliates) (each a “Financial Intermediary”) can help you determine which share class is best suited to your personal financial goals. Investor A, Investor B and Investor C Shares are sometimes referred to herein collectively as “Investor Shares.”

For example, if you select Institutional Shares of the Fund, you will not pay any service fees. However, only certain investors may buy Institutional Shares.

The Fund’s shares are distributed by BlackRock Investments, LLC (the “Distributor”), an affiliate of BlackRock.

The table on the following pages summarizes key features of each of the share classes offered by this prospectus.

The following pages will cover the additional details of each share class, including the eligibility requirements for purchasing Institutional Shares.

Details About the Share Classes

Investor and Institutional Shares are not subject to any sales charge. However, Investor A, Investor B and Investor C Shares may be subject to a sales charge if received in an exchange for the same share class of a BlackRock Equity Fund or a BlackRock Fixed Income Fund. Only certain investors are eligible to buy Institutional Shares. Your Financial Intermediary can help you determine whether you are eligible to buy Institutional Shares. The Fund may permit a lower initial investment for certain investors if their purchase, combined with purchases by other investors received together by the Fund, meets the minimum investment requirement.

Institutional Shares may also be available on certain brokerage platforms. An investor transacting in Institutional Shares through a broker acting as an agent for the investor may be required to pay a commission and/or other forms of compensation to the broker. Shares of the Fund are available in other share classes that have different fees and expenses.

Eligible Institutional Shares investors include the following, provided that the beneficial owners of the Institutional Shares are natural persons:

■	Individuals with a minimum initial investment of $2 million who may purchase shares of the Fund through a Financial Intermediary that has entered into an agreement with the Distributor to purchase such shares;

Table of Contents

■	Investors of Financial Intermediaries that: (i) charge such investors a fee for advisory, investment consulting, or similar services or (ii) have entered into an agreement with the Distributor to offer Institutional Shares through a no-load program or investment platform, in each case, with no minimum initial investment;
■	Clients investing through Financial Intermediaries that have entered into an agreement with the Distributor to offer such shares on a platform that charges a transaction based sales commission outside of the Fund, with a minimum initial investment of $1,000;
■	Employer-sponsored retirement plans (not including SEP IRAs, SIMPLE IRAs or SARSEPs) and state sponsored 529 college savings plans, each of which is not subject to any minimum initial investment and may purchase shares of the Fund through a Financial Intermediary that has entered into an agreement with the Distributor to purchase such shares;
■	Trust department clients of PNC Bank, National Association and Bank of America, N.A. and their affiliates for whom they (i) act in a fiduciary capacity (excluding participant directed employee benefit plans); (ii) otherwise have investment discretion; or (iii) act as custodian for at least $2 million in assets, who are not subject to any minimum initial investment;
■	Holders of certain Bank of America Corporation (“BofA Corp.”) sponsored unit investment trusts (“UITs”) who reinvest dividends received from such UITs in shares of the Fund, who are not subject to any minimum initial investment; and
■	Employees, officers and directors/trustees of BlackRock, Inc., mutual funds sponsored by BlackRock or its affiliates (“BlackRock Funds”), BofA Corp., PNC, Barclays PLC (“Barclays”) or their respective affiliates and immediate family members of such persons, if they open an account directly with BlackRock, who are not subject to any minimum initial investment.

The Fund reserves the right to modify or waive the above-stated policies at any time.

Distribution and Shareholder Servicing Payments

Plan Payments

The Fund has adopted a plan (the “Plan”) that allows the Fund to pay distribution fees for the sale of its shares and shareholder servicing fees for certain services provided to its shareholders.

The distribution fees payable pursuant to the Plan are paid to compensate Financial Intermediaries for distribution and sales support services and related expenses provided in connection with the sale of Investor B and Investor C Shares, as well as shareholder support services, including responding to customer questions on the services performed by the Financial Intermediary and investments in Fund shares, assisting customers in choosing and changing dividend options, account designations and addresses and providing other similar shareholder liaison services. Because the fees paid by the Fund under the Plan are paid out of the Fund’s assets on an ongoing basis, over time these fees will increase the cost of your investment in the Investor B and Investor C Shares of the Fund and may cost you more than paying other types of sales charges.

Other Payments by the Fund

In addition to fees that the Fund may pay to a Financial Intermediary pursuant to the Plan and fees the Fund pays to its transfer agent, BlackRock, on behalf of the Fund, may enter into non-Plan agreements with affiliated and unaffiliated Financial Intermediaries pursuant to which the Fund will pay a Financial Intermediary for administrative, networking, recordkeeping, sub-transfer agency, sub-accounting and/or shareholder services. These non-Plan payments are generally based on either (1) a percentage of the average daily net assets of Fund shareholders serviced by a Financial Intermediary or (2) a fixed dollar amount for each account serviced by a Financial Intermediary. The aggregate amount of these payments may be substantial.

Other Payments by BlackRock

From time to time, BlackRock, the Fund’s distributor or their affiliates also may pay a portion of the fees for administrative, networking, recordkeeping, sub-transfer agency, sub-accounting and shareholder services described above at its or their own expense and out of its or their profits. BlackRock, the Fund’s distributor and their affiliates may also compensate affiliated and unaffiliated Financial Intermediaries for the sale and distribution of shares of the Fund. These payments would be in addition to the Fund payments described in this prospectus and may be a fixed dollar amount, may be based on the number of customer accounts maintained by the Financial Intermediary, may be based on a percentage of the value of shares sold to, or held by, customers of the Financial Intermediary or may be calculated on another basis. The aggregate amount of these payments by BlackRock, the Fund’s distributor and their affiliates may be substantial and, in some circumstances, may create an incentive for a Financial Intermediary, its employees or associated persons to recommend or sell shares of the Fund to you.

Please contact your Financial Intermediary for details about payments it may receive from the Fund or from BlackRock, the Fund’s distributor or their affiliates. For more information, see the SAI.

How to Buy Shares

	Your Choices	Important Information for You to Know
Initial Purchase	First, select the share class appropriate for you	Refer to the “Share Classes at a Glance” table in this prospectus (be sure to read this prospectus carefully). When you place your initial order, you must indicate which share class you select (if you do not specify a share class and do not qualify to purchase Institutional Shares, you will receive Investor A Shares). Certain factors, such as the amount of your investment, your time frame for investing, and your financial goals, may affect which share class you choose. Your financial representative can help you determine which share class is appropriate for you.
	Next, determine the amount of your investment	Refer to the minimum initial investment in the “Share Classes at a Glance” table of this prospectus. See “Account Information — Details about the Share Classes” for information on a lower initial investment requirement for certain Fund investors if their purchase, combined with purchases by other investors received together by the Fund, meets the minimum investment requirement.

Table of Contents

	Your Choices	Important Information for You to Know
Initial Purchase (continued)	Have your Financial Intermediary submit your purchase order	The Fund’s investments are valued based on the amortized cost method described in the SAI. Purchase orders received by the Fund’s transfer agent, BNY Mellon Investment Servicing (US) Inc. (the “Transfer Agent”), before 4:00 p.m. (Eastern time) on each business day will be priced based on the next NAV calculated on that day, and if you send your payment by Federal funds or other immediately available funds no later than the close of the federal funds wire (normally 6:00 p.m. (Eastern time)) you will receive that day’s dividends. NAV is calculated separately for each class of shares of the Fund as of the close of business on the Exchange, generally 4:00 p.m. (Eastern time), each business day. Shares will not be priced on days the Exchange or the Federal Reserve Bank of Philadelphia are closed. The Fund may elect, in its discretion if it is determined to be in shareholders’ best interest, to be open on days when the Exchange is closed due to an emergency. Purchase orders placed after 4:00 p.m. (Eastern time) will be priced at the NAV determined on the next business day. A broker-dealer or financial institution maintaining the account in which you hold shares may charge a separate account, service or transaction fee on the purchase or sale of Fund shares that would be in addition to the fees and expenses shown in the Fund’s “Fees and Expenses” table. The Fund may reject any order to buy shares and may suspend the sale of shares at any time, including when a redemption gate is in place (see “Account Information — Liquidity Fees and Redemption Gates” below).

How to Sell Shares

	Your Choices	Important Information for You to Know
Full or Partial Redemption of Shares	Have your Financial Intermediary submit your sales order	You can make redemption requests through your Financial Intermediary. Shareholders should indicate whether they are redeeming Investor A, Investor B, Investor C or Institutional Shares.

Certain Financial Intermediaries, however, may require submission of orders prior to that time. Any redemption request placed after that time will be priced at the NAV at the close of business on the next business day. Financial Intermediaries may charge a fee to process a redemption of shares. Shareholders should indicate which class of shares they are redeeming. The Fund may reject an order to sell shares under certain circumstances.
	Selling shares held directly with BlackRock	Methods of Redeeming Redeem by Telephone: You may sell Investor Shares held at BlackRock by telephone request if certain conditions are met and if the amount

	Your Choices	Important Information for You to Know
Full or Partial Redemption of Shares (continued)	Selling shares held directly with BlackRock (continued)	being sold is less than (i) $100,000 for payments by check or (ii) $250,000 for payments through ACH or wire transfer. Certain redemption requests, such as those in excess of these amounts, must be in writing with a medallion signature guarantee. For Institutional Shares, certain redemption requests may require written instructions with a medallion signature guarantee. Call (800) 441-7762 for details. You can obtain a medallion signature guarantee stamp from a bank, securities dealer, securities broker, credit union, savings and loan association, national securities exchange or registered securities association. A notary public seal will not be acceptable. The Fund, its administrators and the Distributor will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. The Fund and its service providers will not be liable for any loss, liability, cost or expense for acting upon telephone instructions that are reasonably believed to be genuine in accordance with such procedures. The Fund may refuse a telephone redemption request if it believes it is advisable to do so. During periods of substantial economic or market change, telephone redemptions may be difficult to complete. Please find below alternative redemption methods. Redeem by VRU: Investor Shares may also be redeemed by use of the Fund’s automated VRU service. Proceeds for Investor Shares redeemed by the VRU service may be paid for non-retirement accounts in amounts up to $25,000, either through check, ACH or wire. If the Fund imposes a liquidity fee or a redemption gate, you will not be permitted to use the automated VRU service to redeem shares of the Fund until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted; provided however, you will still be able to redeem shares of the Fund as otherwise described in “How to Sell Shares” during a liquidity fee subject to such liquidity fee. Please see “Account Information — Liquidity Fees and Redemption Gates” below for more information. Redeem by Internet: You may redeem in your account, by logging onto the BlackRock website at www.blackrock.com. Proceeds from Internet redemptions may be sent via check, ACH or wire to the bank account of record. Proceeds for Investor Shares redeemed by Internet may be paid for non-retirement accounts in amounts up to $25,000, either through check, ACH or wire. Different maximums may apply to investors in Institutional Shares. Redeem in Writing: You may sell shares held at BlackRock by writing to BlackRock. All shareholders on the account must sign the letter. A medallion signature guarantee will generally be required but may be waived in certain limited circumstances. You can obtain a medallion signature guarantee stamp from a bank, securities dealer, securities broker, credit union, savings and loan association, national securities exchange or registered securities association. A notary public seal will not be acceptable. If you hold stock certificates, return the certificates with the letter. Proceeds from redemptions may be sent via check, ACH or wire to the bank account of record. Payment of Redemption Proceeds Redemption proceeds may be paid by check or, if the Fund has verified banking information on file, through ACH or by wire transfer. Payment by Check: BlackRock will typically mail redemption proceeds one business day following receipt of a properly completed request, but in any event, within seven days. Shares can be redeemed by telephone and the proceeds sent by check to the shareholder at the address on record. Shareholders will pay $15 for redemption proceeds sent by check via overnight mail. You are responsible for any additional charges imposed by your bank for this service. The Fund reserves the right to reinvest any dividend or distribution amounts (e.g., income dividends or capital gains) which you have

Table of Contents

	Your Choices	Important Information for You to Know
Full or Partial Redemption of Shares (continued)	Selling shares held directly with BlackRock (continued)	elected to receive by check should your check be returned as undeliverable or remain uncashed for more than 6 months. No interest will accrue on amounts represented by uncashed checks. Your check will be reinvested in your account at the NAV next calculated, on the day of the investment. When reinvested, those amounts are subject to the risk of loss like any fund investment. If you elect to receive distributions in cash and a check remains undeliverable or uncashed for more than 6 months, your cash election may also be changed automatically to reinvest and your future dividend and capital gains distributions will be reinvested in the Fund at the NAV as of the date of payment of the distribution. Payment by Wire Transfer: Proceeds for redeemed shares for which a redemption order is received before 4:00 p.m. (Eastern time) on a business day are normally paid in Federal funds wired to the redeeming shareholder on the same business day, provided that the Fund’s custodian is also open for business. Proceeds for redemption orders received on a day when the Fund’s custodian is closed are normally wired in Federal funds on the next business day following redemption on which the Fund’s custodian is open for business. The Fund reserves the right to wire redemption proceeds within seven days after receiving a redemption order if, in the judgment of the Fund, an earlier payment could adversely affect the Fund. If a shareholder has given authorization for expedited redemption, shares can be redeemed by Federal wire transfer to a single previously designated bank account. Shareholders will pay $7.50 for redemption proceeds sent by Federal wire transfer. You are responsible for any additional charges imposed by your bank for this service. No charge for wiring redemption payments with respect to Institutional Shares is imposed by the Fund. The Fund is not responsible for the efficiency of the Federal wire system or the shareholder’s firm or bank. To change the name of the single, designated bank account to receive wire redemption proceeds, it is necessary to send a written request to the Fund at the address on the back cover of this prospectus. Payment by ACH: Redemption proceeds may be sent to the shareholder’s bank account (checking or savings) via ACH. Payment for redeemed shares for which a redemption order is received before 4:00 p.m. (Eastern time) on a business day is normally sent to the redeeming shareholder the next business day, with receipt at the receiving bank within the next two business days (48-72 hours), provided that the Fund’s custodian is also open for business. Payment for redemption orders received after 4:00 p.m. (Eastern time) or on a day when the Fund’s custodian is closed is normally sent on the next business day following redemption on which the Fund’s custodian is open for business. The Fund reserves the right to send redemption proceeds within seven days after receiving a redemption order if, in the judgment of the Fund, an earlier payment could adversely affect the Fund. No charge for sending redemption payments via ACH is imposed by the Fund. *** If you make a redemption request before the Fund has collected payment for the purchase of shares, the Fund may delay mailing your proceeds. This delay will usually not exceed ten days. Please see “Account Information — Liquidity Fees and Redemption Gates” for more information. Under normal and stressed market conditions, the Fund typically expects to meet redemption requests by using cash or cash equivalents in its portfolio or by selling portfolio assets to generate additional cash.

How to Exchange Shares or Transfer your Account

	Your Choices	Important Information for You to Know
Exchange Privilege	Selling shares of one fund to purchase shares of another BlackRock Fund (“exchanging”)	Investor A, Investor B, Investor C and Institutional Shares of the Fund are generally exchangeable for shares of the same class of another BlackRock Fund. You can exchange $1,000 or more of Investor Shares from one fund into the same class of another fund which offers that class of shares (you can exchange less than $1,000 of Investor Shares if you already have an account in the fund into which you are exchanging). Investors who currently own Institutional Shares of the Fund may make exchanges into Institutional Shares of other funds except for investors holding shares through certain client accounts at financial professionals that are omnibus with the Fund and do not meet applicable minimums. There is no required minimum amount with respect to exchanges of Institutional Shares. You may only exchange into a share class and fund that are open to new investors or in which you have a current account if the fund is closed to new investors. Some of the BlackRock Funds impose a sales charge. Therefore the exchange of Investor A Shares may be subject to that sales charge. Investor A Shares of the Fund that were obtained with the exchange privilege and that originally were shares of a BlackRock Fund that were subject to a sales charge can be exchanged for Investor A Shares of a BlackRock Equity Fund or a BlackRock Fixed Income Fund based on their respective NAVs. Exchanges of shares of the Fund for Investor B or Investor C Shares of a BlackRock Equity Fund or a BlackRock Fixed Income Fund may be subject to the applicable contingent deferred sales charge (“CDSC”) upon the sale of these Investor B or Investor C Shares received in exchange. To exercise the exchange privilege, you may contact your Financial Intermediary. Alternatively, if your account is held directly with BlackRock, you may: (i) call (800) 441-7762 and speak with one of our representatives, (ii) make the exchange via the Internet by accessing your account online at www.blackrock.com, or (iii) send a written request to the Fund at the address on the back cover of this prospectus. Please note, if you indicated on your New Account Application that you did not want the Telephone Exchange Privilege, you will not be able to place exchanges via the telephone until you update this option either in writing or by calling (800) 441-7762. The Fund has the right to reject any telephone request for any reason. Although there is currently no limit on the number of exchanges that you can make, the exchange privilege may be modified or terminated at any time in the future. The Fund may suspend or terminate your exchange privilege at any time for any reason, including if the Fund believes, in its sole discretion, that you are engaging in market timing activities. See “Short -Term Trading Policy” below. For Federal income tax purposes a share exchange is a taxable event and a capital gain or loss may be realized. Please consult your tax adviser or other Financial Intermediary before making an exchange request. If the Fund imposes a liquidity fee or a redemption gate, you will not be permitted to exchange into or out of the Fund until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted; provided, however, that you will still be able to redeem shares of the Fund as described above in “How to Sell Shares” during a liquidity fee subject to such liquidity fee. Please see “Account Information — Liquidity Fees and Redemption Gates” below for more information.
Transfer Shares to Another Financial Intermediary	Transfer to a participating Financial Intermediary	You may transfer your shares of the Fund only to another securities dealer that has entered into an agreement with the Distributor. Certain shareholder services may not be available for the transferred shares. All future trading of these assets must be coordinated by the receiving firm.

Account Services and Privileges

The following table provides examples of account services and privileges available in your BlackRock account. Certain of these account services and privileges are only available to shareholders of Investor Shares whose accounts are held directly with BlackRock. If your account is held directly with BlackRock, please call (800) 441-7762 or visit www.blackrock.com for additional information as well as forms and applications. Otherwise, please contact your Financial Intermediary for assistance in requesting one or more of the following services and privileges.

Automatic Investment Plan	Allows systematic investments on a periodic basis from your checking or savings account.	BlackRock’s AIP allows you to invest a specific amount on a periodic basis from your checking or savings account into your investment account. You may apply for this option upon account opening or by completing the AIP application. The minimum investment amount for an automatic investment is $50 per portfolio. If the Fund imposes a liquidity fee or a redemption gate, you will not be permitted to automatically invest through the AIP until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted. Please see “Account Information — Liquidity Fees and Redemption Gates” below for more information.
Dividend Allocation Plan	Automatically invests your distributions into another BlackRock fund of your choice pursuant to your instructions, without any fees or sales charges	Dividend and capital gains distributions may be reinvested in your account to purchase additional shares or paid in cash. Using the Dividend Allocation Plan, you can direct your distributions to your bank account (checking or savings), to purchase shares of another fund at BlackRock without any fees or sales charges, or by check to a special payee. Please call (800) 441-7762 for details. The fund into which you request your distribution be invested must be open to new purchases.
EZ Trader	Allows an investor to purchase or sell Investor Shares by telephone or over the Internet through ACH.	(NOTE: This option is offered to shareholders whose accounts are held directly with BlackRock. Please speak with your Financial Intermediary if your account is held elsewhere). Prior to establishing an EZ Trader account, please contact your bank to confirm that it is a member of the ACH system. Once confirmed, complete an application, making sure to include the appropriate bank information, and return the application to the address listed on the form. Prior to placing a telephone or internet purchase or sale order, please call (800) 441-7762 to confirm that your bank information has been updated on your account. Once this is established, you may place your request to sell shares with the Fund by telephone or Internet. Proceeds will be sent to your pre-designated bank account.
Systematic Exchange Plan	This feature can be used by investors to systematically exchange money from one fund to up to four other funds	A minimum of $10,000 in the initial BlackRock Fund is required and investments in any additional funds must meet minimum initial investment requirements. If the Fund imposes a liquidity fee or a redemption gate, you will not be permitted to use the Systematic Exchange Plan to exchange into or out of the Fund until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted; provided however, you will still be able to redeem shares of the Fund as described above in “How to

Systematic Exchange Plan (continued)	This feature can be used by investors to systematically exchange money from one fund to up to four other funds (continued)	Sell Shares” during a liquidity fee subject to such liquidity fee. Please see “Account Information — Liquidity Fees and Redemption Gates” below for more information.
Systematic Withdrawal Plan (“SWP”)	This feature can be used by investors who want to receive regular distributions from their accounts	To start a SWP a shareholder must have a current investment of $10,000 or more in a BlackRock Fund. Shareholders can elect to receive cash payments of $50 or more at any interval they choose. Shareholders may sign up by completing the SWP Application Form which may be obtained from BlackRock. Shareholders should realize that if withdrawals exceed income the invested principal in their account will be depleted. To participate in the SWP, shareholders must have their dividends reinvested. Shareholders may change or cancel the SWP at any time, with a minimum of 24 hours notice. If a shareholder purchases additional Investor A Shares of a BlackRock Fund at the same time he or she redeems shares through the SWP, that investor may lose money because of the sales charge involved. No CDSC will be assessed on redemptions of Investor Shares made through the SWP that do not exceed 12% of the account’s NAV on an annualized basis. For example, monthly, quarterly and semi-annual SWP redemptions of Investor Shares will not be subject to the CDSC if they do not exceed 1%, 3% and 6%, respectively, of an account’s NAV on the redemption date. SWP redemptions of Investor Shares in excess of this limit will still pay any applicable CDSC. Ask your Financial Intermediary for details. If the Fund imposes a liquidity fee or redemption gate, you will not be permitted to systematically withdraw your shares through the SWP until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted; provided however, you will still be able to redeem shares of the Fund as described above in “How to Sell Shares” during a liquidity fee subject to such liquidity fee. Please see “Account Information — Liquidity Fees and Redemption Gates” below for more information.

Fund’s Rights

The Fund may:

■	Suspend the right of redemption if trading is halted or restricted on the Exchange or under other emergency conditions described in the Investment Company Act;
■	Postpone the date of payment upon redemption if trading is halted or restricted on the Exchange or under other emergency conditions described in the Investment Company Act or if a redemption request is made before the Fund has collected payment for the purchase of shares;
■	Redeem shares for property other than cash as may be permitted under the Investment Company Act; and
■	Redeem shares involuntarily in certain cases, such as when the value of a shareholder account falls below a specified level or if the Fund does not believe the account is for a natural person.

Suspension of Redemptions Upon Liquidation. If the Board, including a majority of the trustees who are not “interested persons” of the Trust as defined in the Investment Company Act, determines either that (1) the Fund has invested, at the end of a business day, less than 10% of its total assets in weekly liquid assets, or (2) the Fund’s calculated NAV per share has deviated from $1.00 or such deviation is likely to occur; then the Board, subject to certain conditions, may, where the Board has determined to liquidate the Fund irrevocably, suspend redemptions and payment of redemption proceeds in order to facilitate the permanent liquidation of the Fund in an orderly manner. If this were to occur, it would likely result in a delay in your receipt of your redemption proceeds.

Note on Low Balance Accounts. Because of the high cost of maintaining smaller shareholder accounts, BlackRock has set a minimum balance of $500 in each Fund position you hold within your account (the “Fund Minimum”), and may redeem the shares in your account if the NAV of those shares in your account falls below $500 for any reason, including market fluctuation.

Table of Contents

You will be notified that the value of your account is less than the Fund Minimum before the Fund makes any involuntary redemption. This notification will provide you with a 90 calendar day period to make an additional investment in order to bring the value of your account to at least $500 before the Fund makes an involuntary redemption. This involuntary redemption will not charge any deferred sales charge, and may not apply to accounts of certain employer-sponsored retirement plans (not including IRAs), qualified state tuition plan (529 Plan) accounts, and select fee-based programs at your Financial Intermediary.

Liquidity Fees and Redemption Gates

Under Rule 2a-7, the Board is permitted to impose a liquidity fee up to 2% on the value of shares redeemed or temporarily restrict redemptions from the Fund for up to 10 business days during a 90 day period, in the event that the Fund’s weekly liquid assets fall below the following thresholds:

■

30% weekly liquid assets — If the weekly liquid assets of the Fund fall below 30% of the Fund’s total assets, and the Board determines it is in the best interests of the Fund, the Board may impose at any time, and as early as the same day, a liquidity fee of up to 2% of the amount redeemed, or a redemption gate that temporarily suspends the right of redemption.

■

10% weekly liquid assets — If the weekly liquid assets of the Fund fall below 10% of the Fund’s total assets as of the end of a business day, the Board will impose, at the beginning of the next business day, a liquidity fee of 1% of the amount redeemed, unless the Board determines that imposing such a fee would not be in the best interests of the Fund or determines that a lower or higher fee (not to exceed 2%) would be in the best interests of the Fund.

Liquidity fees and redemption gates, if imposed, may be terminated at any time in the discretion of the Board. Liquidity fees and redemption gates will also automatically terminate at the beginning of the next business day once the Fund has invested 30% or more of its total assets in weekly liquid assets as of the end of a business day.

If the Board imposes a liquidity fee, the fee will be used to help boost the weekly liquid assets of the Fund. The Fund may not accept purchases during the period that a liquidity fee has been imposed.

If the Board imposes a redemption gate, the Fund will not accept purchase or redemption orders until the Fund has notified shareholders that the redemption gate has been lifted. Any purchase or redemption orders submitted while a redemption gate is in effect will be cancelled without further notice. If you still wish to purchase or redeem shares once the redemption gate has been lifted, you will need to submit a new purchase or redemption request to the Fund or your Financial Intermediary. If a purchase or redemption order is received after the applicable deadline of the Fund, but prior to the imposition of a liquidity fee or a redemption gate, such order will be cancelled without further notice.

If the Board imposes a liquidity fee or a redemption gate, the Fund will not accept exchange orders into or out of the Fund until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted.

Under certain circumstances, the Fund may honor redemption or exchange orders (or pay redemptions without adding a liquidity fee to the redemption amount) if the Fund can verify that the redemption or exchange order was submitted to the Fund’s authorized agent before the Board imposed a liquidity fee or suspended redemptions.

The Board generally expects that a liquidity fee or redemption gate would be imposed, if at all, during periods of extraordinary market stress. The Board expects that a liquidity fee or redemption gate would typically be imposed only after the Fund has notified Financial Intermediaries and shareholders that a liquidity fee or redemption gate will be imposed (which may not be until the beginning of the next business day following the announcement that the Board has imposed the liquidity fee or redemption gate). However, the Board may, in its discretion, impose a liquidity fee or redemption gate at any time after the weekly liquid assets of the Fund fall below 30% of the Fund’s total assets.

Announcements regarding the imposition of a liquidity fee or redemption gate, or the termination of a liquidity fee or redemption gate, will be filed with the SEC on Form N-CR and will be available on the website of the Fund (www.blackrock.com/cash). In addition, the Fund will make such announcements through a supplement to their registration statements and may further communicate such actions through other means.

Financial Intermediaries will be required promptly to take such actions reasonably requested by the Fund or its agent to implement, modify or remove, or to assist the Fund in implementing, modifying or removing, a liquidity fee or redemption gate established by the Board.

Short-Term Trading Policy

Market timing is an investment technique involving frequent short-term trading of mutual fund shares designed to exploit market movements or inefficiencies in the way a mutual fund prices its shares. The Board has evaluated the risks of market timing activities by the Fund’s shareholders and has determined that due to (i) the Fund’s policy of seeking to maintain the Fund’s NAV per share at $1.00 each day, (ii) the nature of the Fund’s portfolio holdings, and (iii) the nature of the Fund’s shareholders, it is unlikely that (a) market timing would be attempted by the Fund’s shareholders or (b) any attempts to market time the Fund by shareholders would result in a negative impact to the Fund or its shareholders. As a result, the Board has not adopted policies and procedures to deter short-term trading in the Fund. There can be no assurances, however, that the Fund may not, on occasion, serve as a temporary or short-term investment vehicle for those who seek to market time funds offered by other investment companies.

Master/Feeder Structure

The Fund may in the future determine to become a “feeder” fund that invests all of its assets in another open-end investment company (a “master fund”) that has the same investment objective and strategies as the Fund. This structure is sometimes called a “master/feeder” structure. Investors in a feeder fund will acquire an indirect interest in the corresponding master fund. In a master/feeder structure, all investments will be made at the master level and the Fund’s investment results will correspond directly to the investment results of the underlying master in which it invests. A feeder fund may withdraw from its master fund at any time and may invest all of its assets in another pooled investment vehicle or retain an investment adviser to manage its assets directly.

A master fund may accept investments from other feeder funds, and all the feeder funds of a given master fund bear the master fund’s expenses in proportion to their assets. This structure may enable the feeder funds to reduce costs through economies of scale. A larger investment portfolio may also reduce certain transaction costs to the extent that contributions to and redemptions from a master fund from different feeder funds may offset each other and produce a lower net cash flow.

However, each feeder fund can set its own transaction minimums, fund specific expenses, and other conditions. This means that one feeder fund could offer access to the same master fund on more attractive terms, or could experience better performance, than another feeder fund. In addition, large purchases or redemptions by one feeder fund could negatively affect the performance of other feeder funds that invest in the same master fund.

Whenever a master fund holds a vote of its feeder funds, a fund that is a feeder fund investing in that master fund will pass the vote through to its own shareholders. Smaller feeder funds may be harmed by the actions of larger feeder funds. For example, a larger feeder fund could have more voting power than a fund that is a feeder fund over the operations of its master fund.

Management of the Fund

BlackRock

BlackRock, the Fund’s investment adviser, manages the Fund’s investments and its business operations subject to the oversight of the Board. While BlackRock is ultimately responsible for the management of the Fund, it is able to draw upon the research and expertise of its asset management affiliates for portfolio decisions and management with respect to certain portfolio securities. BlackRock is an indirect, wholly-owned subsidiary of BlackRock, Inc.

BlackRock, a registered investment adviser, was organized in 1994 to perform advisory services for investment companies. BlackRock and its affiliates had approximately $5.689 trillion in investment company and other portfolio assets under management as of June 30, 2017.

BlackRock serves as manager to the Fund pursuant to a management agreement (the “Management Agreement”), which provides that BlackRock is entitled to fees computed daily and payable monthly. The maximum annual management fee rate that the Fund can pay to BlackRock (as a percentage of average daily net assets) is calculated as follows:

Average Daily Net Assets	Rate of Management Fee
First $1 billion	0.450%
$1 billion - $2 billion	0.400%
$2 billion - $3 billion	0.375%
Greater than $3 billion	0.350%

BlackRock has contractually agreed to cap net expenses (excluding: (i) interest, taxes, dividends tied to short sales, brokerage commissions, and other expenditures which are capitalized in accordance with generally accepted accounting principles; (ii) expenses incurred directly or indirectly by the Fund as a result of investments in other investment companies and pooled investment vehicles; (iii) other expenses attributable to, and incurred as a result of, the Fund’s investments; and (iv) other extraordinary expenses not incurred in the ordinary course of the Fund’s business, if any) of each share class of Fund at the levels shown below and in the Fund’s fees and expenses table in the “Fund Overview” section. Items (i), (ii), (iii) and (iv) in the preceding sentence are referred to in this prospectus as “Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses.” To achieve these expense caps, BlackRock has agreed to waive and/or reimburse fees or expenses if these operating expenses exceed a certain limit.

With respect to the Fund, BlackRock has contractually agreed to waive and/or reimburse fees or expenses in order to limit Total Annual Fund Operating Expenses to the amounts noted in the table below.

	Contractual Caps ¹ on Total Annual Operating Expenses ² (excluding Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses)
Investor A	0.55%
Investor B	1.30%
Investor C	1.30%
Institutional	0.20%

¹	The contractual caps are in effect through July 31, 2018. The contractual 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.
²	As a percentage of average daily net assets.

BlackRock and the Distributor have voluntarily agreed to waive a portion of their respective fees and/or reimburse operating expenses to enable the Fund to maintain minimum levels of daily net investment income. BlackRock and the Distributor may discontinue this voluntary waiver and/or reimbursement at any time without notice.

Table of Contents

With respect to the contractual agreement to cap net expenses, if during the Fund’s fiscal year the operating expenses of a share class, that at any time during the prior two fiscal years received a waiver or reimbursement from BlackRock, are less than the expense limit for that share class, the share class is required to repay BlackRock up to the lesser of (a) the amount of fees waived or expenses reimbursed during those prior two fiscal years under the agreement and (b) the amount by which the expense limit for that share class exceeds the operating expenses of the share class for the current fiscal year, provided that (i) the Fund of which the share class is a part has more than $50 million in assets and (ii) BlackRock or an affiliate serves as the Fund’s manager or administrator. This repayment applies only to the contractual caps on net expenses and does not apply to any voluntary waivers that may be in effect from time to time. The Fund may only make repayments to BlackRock of amounts waived and/or reimbursed by BlackRock if such repayments do not cause the Fund’s net expense ratio, taking into account such repayments, to exceed either: (i) the Fund’s expense cap in place at the time such waivers and/or reimbursements were made; or (ii) the Fund’s current expense cap at the time of such repayment.

For the fiscal year ended March 31, 2017, the Fund paid BlackRock aggregate management fees, net of any applicable waivers, equal to 0.12% of the Fund’s average daily net assets.

A discussion of the basis for the Board’s approval of the Management Agreement with respect to the Fund is included in the Fund’s semi-annual shareholder report for the fiscal period ended September 30, 2016.

From time to time, a manager, analyst, or other employee of BlackRock or its affiliates may express views regarding a particular asset class, company, security, industry, or market sector. The views expressed by any such person are the views of only that individual as of the time expressed and do not necessarily represent the views of BlackRock or any other person within the BlackRock organization. Any such views are subject to change at any time based upon market or other conditions and BlackRock disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for the Fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of the Fund.

Legal Proceedings. On May 27, 2014, certain purported investors in the BlackRock Global Allocation Fund, Inc. (“Global Allocation”) and the BlackRock Equity Dividend Fund (“Equity Dividend”) filed a consolidated complaint (the “Consolidated Complaint”) in the United States District Court for the District of New Jersey against BlackRock Advisors, LLC, BlackRock Investment Management, LLC and BlackRock International Limited (collectively, the “Defendants”) under the caption In re BlackRock Mutual Funds Advisory Fee Litigation . The Consolidated Complaint, which purports to be brought derivatively on behalf of Global Allocation and Equity Dividend, alleges that the Defendants violated Section 36(b) of the Investment Company Act by receiving allegedly excessive investment advisory fees from Global Allocation and Equity Dividend. The Consolidated Complaint seeks, among other things, to recover on behalf of Global Allocation and Equity Dividend all allegedly excessive advisory fees received by the Defendants in the period beginning one year prior to the filing of the lawsuit and ending on the date of judgment, along with purported lost investment returns on those amounts, plus interest. The Defendants believe the claims in the Consolidated Complaint are without merit and intend to vigorously defend the action.

Conflicts of Interest

The investment activities of BlackRock and its affiliates (including BlackRock, Inc. and PNC and their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders.

BlackRock and its Affiliates provide investment management services to other funds and discretionary managed accounts that follow investment programs similar to those of the Fund. BlackRock and its Affiliates are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. One or more Affiliates act or may act as an investor, investment banker, research provider, investment manager, commodity pool operator, commodity trading advisor, financier, underwriter, adviser, market maker, trader, prime broker, lender, index provider, agent and principal, and have other direct and indirect interests in securities, currencies, commodities, derivatives and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which an Affiliate performs or seeks to perform investment banking or other services. Specifically, the Fund may invest in securities of, or engage in other transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships or in which an Affiliate has significant debt or equity investments or other interests. The Fund also may invest in securities of, or engage in other transactions with, companies for which an Affiliate provides or may in the

Table of Contents

future provide research coverage. An Affiliate may have business relationships with, and purchase, or distribute or sell services or products from or to, distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates in connection with the Fund’s portfolio investment transactions. An Affiliate may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund. This may include transactions in securities issued by other open-end and closed-end investment companies (which may include investment companies that are affiliated with the Fund and BlackRock, to the extent permitted under the Investment Company Act). The trading activities of these Affiliates are carried out without reference to positions held directly or indirectly by the Fund and may result in an Affiliate having positions in certain securities that are senior or junior to, or have interests different from or adverse to, the securities that are owned by the Fund.

No Affiliate is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate may compete with the Fund for appropriate investment opportunities. The results of the Fund’s investment activities, therefore, may differ from those of an Affiliate and of other accounts managed by an Affiliate, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

In addition, the Fund may, from time to time, enter into transactions in which an Affiliate or its other clients have an adverse interest. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate-advised clients or BlackRock may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund. The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates and/or their internal policies designed to comply with such restrictions.

Under a securities lending program approved by the Board, the Trust, on behalf of the Fund, has retained BlackRock Investment Management, LLC, an Affiliate of BlackRock, to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent will receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for the loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of Affiliates may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BlackRock has adopted policies and procedures designed to address these potential conflicts of interest. See the SAI for further information.

Valuation of Fund Investments

A mutual fund is a pool of investors’ money that is used to purchase a portfolio of securities, which in turn is owned in common by the investors. Investors put money into a mutual fund by buying shares. If a mutual fund has a portfolio worth $5 million and has 5 million shares outstanding, the NAV per share is $1.00. When you buy Investor or Institutional Shares you pay the NAV per share. Although the Fund seeks to maintain an NAV of $1.00 per share, there is no guarantee it will be able to do so.

The Fund’s investments are valued based on the amortized cost method described in the SAI.

The Transfer Agent will probably receive your order from your registered representative, who takes your order. However, you can also fill out a purchase application and mail it to the Transfer Agent with your check. Please call (800) 441-7762 for a purchase application. Purchase orders received by the Transfer Agent before 4:00 p.m. (Eastern time) on each business day will be priced based on the next NAV calculated on that day, and if you send your payment by Federal funds or other immediately available funds no later than the close of the federal funds wire (normally 6:00 p.m. (Eastern time)) you will receive that day’s dividends.

The NAV is calculated separately for each class of shares of the Fund as of the close of business on the Exchange, generally 4:00 p.m. (Eastern time), each business day. Shares will not be priced on days the Exchange or the Federal Reserve Bank of Philadelphia are closed. The Fund may elect, in its discretion if it is determined to be in shareholders’ best interest, to be open on days when the Exchange is closed due to an emergency.

Dividends, Distributions and Taxes

BUYING A DIVIDEND

Unless your investment is in a tax-deferred account, you may want to avoid buying shares shortly before the Fund pays a dividend. The reason? If you buy shares when the Fund has declared but not yet distributed ordinary income or capital gains, you will pay the full price for the shares and then receive a portion of the price back in the form of a taxable dividend. Before investing you may want to consult your tax adviser.

Distributions of net investment income derived by the Fund, if any, are declared daily and paid at least monthly and net realized capital gains, if any, will be distributed at least annually. Dividends will be reinvested automatically in the form of additional shares of the same class of the Fund at NAV unless you instruct the Transfer Agent in writing to pay them in cash. Dividends that are declared but unpaid will remain in the gross assets of the Fund and will, therefore, continue to earn income for the Fund’s shareholders. Shareholders redeeming their shares will receive all dividends declared through the date immediately preceding the date of redemption. The Fund anticipates that a significant amount of the distributions may be taxed as ordinary income, although the Fund may distribute capital gains as well. Capital gains may be taxable to you at different rates depending on how long the Fund held the assets sold.

You will pay tax on dividends derived from taxable interest and on capital gain distributions from the Fund whether you receive them in cash or additional shares. If you redeem Fund shares or exchange them for shares of another fund, you generally will be treated as having sold your shares and any gain on the transaction may be subject to tax. Certain dividend income and long-term capital gains are eligible for taxation at a reduced rate that applies to non-corporate shareholders. However, to the extent that the Fund’s distributions are derived from income on debt securities and from short-term capital gains, such distributions will not be eligible for taxation at the reduced rate.

If the Fund imposes a liquidity fee on share redemptions because of a drop in the Fund’s weekly liquid assets below certain levels, the amount that would ordinarily be payable to a redeeming shareholder of the Fund will be reduced, consequently reducing the amount of gain, or increasing the amount of loss, that would otherwise be reportable for income tax purposes. The liquidity fee cannot be separately claimed as a deduction.

Any such liquidity fee will constitute an asset of the Fund and will serve to benefit non-redeeming shareholders. However, the Fund does not intend to distribute such fees to non-redeeming shareholders. If the Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.

If the value of assets held by the Fund declines, the Board may authorize a reduction in the number of outstanding shares in shareholders’ accounts so as to preserve a net asset value of $1.00 per share. After such a reduction, the basis of eliminated shares would be added to the basis of shareholders’ remaining Fund shares, and you could recognize a capital loss if you disposed of your shares at that time. Dividends, including dividends reinvested in additional shares of the Fund, will nonetheless be fully taxable, even if the number of shares in your account has been reduced as described above.

A 3.8% Medicare tax is imposed on the net investment income (which includes, but is not limited to, interest, dividends and net gain from investments) of U.S. individuals with income exceeding $200,000, or $250,000 if married filing jointly, and of trusts and estates.

By law, your taxable dividends and redemption proceeds will be subject to a 28% withholding tax if you have not provided a taxpayer identification number or social security number to the Fund in which you invest or the number you have provided is incorrect.

If you are neither a tax resident nor a citizen of the United States or if you are a foreign entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gain) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies. However, certain distributions reported by the Fund as either interest related dividends or short-term capital gain dividends and paid to a foreign shareholder may be eligible for an exemption from U.S. withholding tax.

A 30% withholding tax is currently imposed on U.S.-source dividends, interest and other income items and will be imposed on proceeds from the sale, redemption or other disposition of property producing U.S.-source dividends and interest paid after December 31, 2018, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to (i) enter into agreements with the IRS that state that they will provide the IRS information, including the names, addresses and taxpayer identification numbers of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts,

Table of Contents

agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders that fail to provide the required information, and determine certain other information concerning their account holders, or (ii) in the event that an applicable intergovernmental agreement and implementing legislation are adopted, provide local revenue authorities with similar account holder information. Other foreign entities will need to either provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

This section summarizes some of the consequences under current Federal tax law of an investment in the Fund. This discussion is not a substitute for individualized tax advice. You should consult your tax adviser about the potential tax consequences of an investment in the Fund under all applicable tax laws.

Glossary

This glossary contains an explanation of some of the common terms used in this prospectus. For additional information about the Fund, please see the SAI.

Acquired Fund Fees and Expenses — fees and expenses charged by other investment companies in which the Fund invests a portion of its assets.

Annual Fund Operating Expenses — expenses that cover the costs of operating the Fund.

Daily Liquid Assets — include (i) cash; (ii) direct obligations of the U.S. Government; (iii) securities that will mature, as determined without reference to the maturity shortening provisions of Rule 2a-7 regarding interest rate readjustments, or are subject to a demand feature that is exercisable and payable within one business day; and (iv) amounts receivable and due unconditionally within one business day on pending sales of portfolio securities.

Dollar-Weighted Average Life — the dollar-weighted average maturity of the Fund’s portfolio calculated without reference to the exceptions used for variable or floating rate securities regarding the use of interest rate reset dates in lieu of the security’s actual maturity date. “Dollar-weighted” means the larger the dollar value of a debt security in the Fund, the more weight it gets in calculating this average.

Dollar-Weighted Average Maturity — the average maturity of the Fund is the average amount of time until the organizations that issued the debt securities in the Fund’s portfolio must pay off the principal amount of the debt. “Dollar-weighted” means the larger the dollar value of a debt security in the Fund, the more weight it gets in calculating this average. To calculate the dollar-weighted average maturity, the Fund may treat a variable or floating rate security as having a maturity equal to the time remaining to the security’s next interest rate reset date rather than the security’s actual maturity.

Distribution Fees — fees used to support the Fund’s marketing and distribution efforts, such as compensating Financial Intermediaries, advertising and promotion.

Eligible Securities — Applicable Eligible Securities include:

■	securities with a remaining maturity of 397 calendar days or less (with certain exceptions) that BlackRock determines present minimal credit risks to the Fund after considering certain factors;
■	securities issued by other registered investment companies that are money market funds; or
■	securities issued or guaranteed as to principal or interest by the U.S. Government or any of its agencies or instrumentalities.

Interest Expense — the cost of borrowing money to buy additional securities, primarily through reverse repurchase agreements (under which the Fund sells securities and agrees to buy them back at a particular date and price).

Management Fee — a fee paid to BlackRock for managing the Fund.

Other Expenses — include accounting, administration, transfer agency, custody, professional and registration fees.

Service Fees — fees used to compensate Financial Intermediaries for certain shareholder servicing activities.

Weekly Liquid Assets — include (i) cash; (ii) direct obligations of the U.S. Government; (iii) U.S. Government securities issued by a person controlled or supervised by and acting as an instrumentality of the U.S. Government pursuant to authority granted by the U.S. Congress, that are issued at a discount to the principal amount to be repaid at maturity without provision for the payment of interest and have a remaining maturity of 60 days or less; (iv) securities that will mature, as determined without reference to the maturity shortening provisions of Rule 2a-7 regarding interest rate readjustments, or are subject to a demand feature that is exercisable and payable within five business days; and (v) amounts receivable and due unconditionally within five business days on pending sales of portfolio securities.

Principal Risks of Investing in the Fund

The following is a summary description of principal risks of investing in the Fund.

■

■	Extension Risk — When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.

■

	The profitability of many types of financial services companies may be adversely affected in certain market cycles, including periods of rising interest rates, which may restrict the availability and increase the cost of capital, and declining economic conditions, which may cause credit losses due to financial difficulties of borrowers. Because many types of financial services companies are vulnerable to these economic cycles, a large portion of the Fund’s investments may lose value during such periods.
■	Foreign Exposure Risk — Securities issued or supported by foreign entities, including foreign banks and corporations, may involve additional risks and considerations. Extensive public information about the foreign issuer may not be available, and unfavorable political, economic or governmental developments in the foreign country involved could affect the payment of principal and interest.
■	Income Risk — Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates.
■	Interest Rate Risk — Interest rate risk is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter-term securities. Due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund.
■	Liquidity Fee and Redemption Gate Risk — The Board has discretion to impose a liquidity fee of up to 2% upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. Accordingly, you may not be able to sell your shares or your redemptions may be subject to a liquidity fee when you sell your shares at certain times.
■	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

Table of Contents

	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.
■	Prepayment Risk — When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.
■	Repurchase Agreements and Purchase and Sale Contracts Risk — If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the Fund may lose money.
■	Stable Net Asset Value Risk — The Fund may not be able to maintain a stable NAV of $1.00 per share at all times. If the Fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), the Fund, along with other money market funds, could be subject to increased redemption activity.
■	U.S. Government Obligations Risk — Certain securities in which the Fund may invest, including securities issued by certain U.S. Government agencies and U.S. Government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States.
■	Variable and Floating Rate Instrument Risk — The absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults.
■	When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Details About the Fund

How the Fund Invests

The Fund is a retail money market fund managed pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

■	The Fund seeks to maintain a net asset value (“NAV”) of $1.00 per share.
■	The Fund will maintain a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. For a discussion of dollar-weighted average maturity and dollar-weighted average life, please see the Glossary on page 27.
■	Pursuant to Rule 2a-7, the Fund is subject to a “general liquidity requirement” that requires that the Fund hold securities that are sufficiently liquid to meet reasonably foreseeable shareholder redemptions in light of its obligations under Section 22(e) of the Investment Company Act regarding share redemptions and any commitments the Fund has made to shareholders. To comply with this general liquidity requirement, BlackRock Advisors, LLC (“BlackRock”) must consider factors that could affect the Fund’s liquidity needs, including characteristics of the Fund’s investors and their likely redemptions. Depending upon the volatility of its cash flows (particularly shareholder redemptions), this may require the Fund to maintain greater liquidity than would be required by the weekly minimum liquidity requirement discussed below.
■	The Fund will not acquire any illiquid security (i.e., securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund) if, immediately following such purchase, more than 5% of the Fund’s total assets are invested in illiquid securities. The Fund will not acquire any security other than a daily liquid asset unless, immediately following such purchase, at least 10% of its total assets would be invested in daily liquid assets, and the Fund will not acquire any security other than a weekly liquid asset unless, immediately following such purchase, at least 30% of its total assets would be invested in weekly liquid assets. For a discussion of daily liquid assets and weekly liquid assets, please see the Glossary on page 27.
■	The Fund invests in securities maturing within 13 months or less from the date of purchase, with certain exceptions. For example, certain government securities held by the Fund may have remaining maturities exceeding 13 months if such securities provide for adjustments in their interest rates not less frequently than every 13 months.
■	The securities purchased by the Fund are subject to the quality, diversification, and other requirements of Rule 2a-7, and other rules of the Securities and Exchange Commission (the “SEC”). The Fund will purchase securities (or issuers of such securities) that are Eligible Securities that present minimal credit risk as determined by BlackRock pursuant to guidelines approved by the Trust’s Board of Trustees (the “Board”). For a discussion of Eligible Securities, please see the Glossary on page 27.

Investment Objective

The investment objective of the Fund is to seek as high a level of current income as is consistent with maintaining liquidity and stability of principal.

Table of Contents

Principal Investment Strategies

■	U.S. dollar-denominated obligations issued or supported by the credit of U.S. or foreign banks or savings institutions with total assets of more than $1 billion (including obligations of foreign branches of such banks)

■

■	Unrated notes, paper and other instruments that are determined by Fund management to be of comparable quality to the instruments described above
■	Asset-backed securities (including interests in “pools” of assets such as mortgages, installment purchase obligations and credit card receivables)
■	Securities issued or guaranteed by the U.S. Government or by its agencies or authorities
■	Dollar-denominated securities issued or guaranteed by foreign governments or their political subdivisions, agencies or authorities
■	Repurchase agreements relating to the above instruments

Other Strategies

In addition to the principal strategies discussed above, the Fund may also invest or engage in the following investments/strategies:

■	Investment Company Securities — The Fund may invest in securities issued by other open-end or closed-end investment companies as permitted by the Investment Company Act. A pro rata portion of the other investment companies’ expenses may be borne by the Fund’s shareholders. These investments may include, as consistent with the Fund’s investment objective and policies, certain variable rate demand securities issued by closed-end funds, which invest primarily in portfolios of taxable or tax-exempt securities. It is anticipated that the payments made on the variable rate demand securities issued by closed-end municipal bond funds will be exempt from federal income tax.
■	Uninvested Cash Reserves — The Fund may hold up to 20% of its assets in uninvested cash reserves. Uninvested cash reserves will not earn income.
■	U.S. Treasury Floating Rate Notes — The Fund may invest in U.S. Treasury Floating Rate Notes (FRNs). These are two-year notes issued by the U.S. Treasury that reset their interest rates on a weekly basis. At maturity, the face value of an FRN is paid to the note holder.

Investment Risks

Table of Contents

to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time.

The following is a description of certain risks of investing in the Fund.

Principal Risks of Investing in the Fund

■	Asset-Backed Securities Risk — Asset-backed securities represent interests in “pools” of assets, including consumer loans or receivables held in trust. Asset-backed securities, like traditional fixed-income securities, are subject to credit, interest rate, prepayment and extension risks.
	The Fund’s investments in asset-backed securities are subject to additional risks associated with the nature of the assets and the servicing of those assets. These securities also are subject to the risk of default on the underlying assets, particularly during periods of economic downturn.
	Asset-backed securities entail further risks, including the risk that, in certain states, it may be difficult to perfect the liens securing the collateral backing certain asset-backed securities. In addition, certain asset-backed securities are based on loans that are unsecured, which means that there is no collateral to seize if the underlying borrower defaults.
■	Credit Risk — Credit risk refers to the possibility that the issuer of a security will not be able to make principal and interest payments 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. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

■

■	Foreign Exposure Risk — Securities issued or supported by foreign entities, including foreign banks and corporations, may involve additional risks and considerations. Extensive public information about the foreign issuer may not be available, and unfavorable political, economic or governmental developments in the foreign country involved could affect the payment of principal and interest.
■	Income Risk — The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates.
■	Interest Rate Risk — Interest rate risk is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter-term securities. Due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund.
■	Liquidity Fee and Redemption Gate Risk — The Board has discretion to impose a liquidity fee of up to 2% upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. Accordingly, you may not be able to sell your shares or your redemptions may be subject to a liquidity fee when you sell your shares at certain times.

Table of Contents

■	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.
■	Prepayment Risk — When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields. In periods of falling interest rates, the rate of prepayments tends to increase (as does price fluctuation) as borrowers are motivated to pay off debt and refinance at new lower rates. During such periods, reinvestment of the prepayment proceeds by the management team will generally be at lower rates of return than the return on the assets that were prepaid. Prepayment reduces the yield to maturity and the average life of the security.
■	Repurchase Agreements and Purchase and Sale Contracts Risk — If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the Fund may lose money.
■	Stable Net Asset Value Risk — The Fund may not be able to maintain a stable NAV of $1.00 per share at all times. If the Fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), the Fund, along with other money market funds, could be subject to increased redemption activity.
■	U.S. Government Obligations Risk — Not all U.S. Government securities are backed by the full faith and credit of the United States. Obligations of certain agencies, authorities, instrumentalities and sponsored enterprises of the U.S. Government are backed by the full faith and credit of the United States (e.g., the Government National Mortgage Association); other obligations are backed by the right of the issuer to borrow from the U.S. Treasury (e.g., the Federal Home Loan Banks) and others are supported by the discretionary authority of the U.S. Government to purchase an agency’s obligations. Still others are backed only by the credit of the agency, authority, instrumentality or sponsored enterprise issuing the obligation. No assurance can be given that the U.S. Government would provide financial support to any of these entities if it is not obligated to do so by law.
■	Variable and Floating Rate Instrument Risk — The absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults.
■	When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Other Risks of Investing in the Fund

The Fund may also be subject to certain other risks associated with its investments and investment strategies, including:

■

■	Liquidity Risk — Liquidity risk refers to the possibility that it may be difficult or impossible to sell certain positions at an acceptable price.

Account Information

How to Choose the Share Class that Best Suits Your Needs

The Fund currently offers multiple share classes (Service Shares in this prospectus), allowing you to invest in the way that best suits your needs. Each share class represents an ownership interest in the same investment portfolio of the Fund. When you choose your class of shares, you should consider the size of your investment and how long you plan to hold your shares. Either your financial professional or your selected securities dealer, broker, investment adviser, service provider or industry professional (including BlackRock, The PNC Financial Services Group, Inc. (“PNC”) and their respective affiliates) (each a “Financial Intermediary”) can help you determine which share class is best suited to your personal financial goals.

The Fund’s shares are distributed by BlackRock Investments, LLC (the “Distributor”), an affiliate of BlackRock.

The table below summarizes key features of the Service Share class of the Fund.

Service Shares at a Glance

Service Shares will normally be held by Financial Intermediaries or in the name of nominees of Financial Intermediaries on behalf of their customers. Service Shares are normally purchased through a customer’s account at a Financial Intermediary through procedures established by such Financial Intermediary. In these cases, confirmation of share purchases and redemptions will be sent to the Financial Intermediaries. A customer’s ownership of shares will be recorded by the Financial Intermediary and reflected in the account statements provided by such Financial Intermediaries to their customers. Investors wishing to purchase Service Shares should contact their Financial Intermediaries.

Advantage	No up-front sales charge so you start off owning more shares.
Disadvantage	Limited availability.

Distribution and Shareholder Servicing Payments

Plan Payments

The Fund has adopted a plan (the “Plan”) with respect to Service Shares that allows the Fund to pay distribution and service fees for the sale of its shares and shareholder servicing fees for certain services provided to its shareholders. The Fund does not make distribution payments under the Plan with respect to Service Shares.

The shareholder servicing fees payable pursuant to the Plan are paid to compensate Financial Intermediaries for providing support services to their customers who own Service Shares, including responding to customer questions on the services performed by the Financial Intermediary and investments in Service Shares, assisting customers in choosing and changing dividend options, account designations and addresses and providing other similar shareholder liaison services. Because the fees paid by the Fund under the Plan are paid out of the Fund’s assets on an ongoing

Table of Contents

basis, over time these fees will increase the cost of your investment in the Service Shares of the Fund and may cost you more than paying other types of sales charges.

Other Payments by the Fund

Other Payments by BlackRock

Please contact your Financial Intermediary for details about payments it may receive from the Fund or from BlackRock, the Fund’s distributor or their affiliates. For more information, see the SAI.

How to Buy, Sell and Transfer Shares

Because the selection of a mutual fund involves many considerations, your Financial Intermediary may help you with this decision.

With certain limited exceptions, the Fund is generally available only to investors residing in the United States and may not be distributed by a foreign Financial Intermediary. Under this policy, in order to accept new accounts or additional investments into existing accounts, the Fund generally requires that (i) a shareholder that is a natural person be a U.S. citizen or resident alien, in each case residing within the United States or a U.S. territory (including APO/FPO/DPO addresses), and have a valid U.S. taxpayer identification number, and (ii) a Financial Intermediary or a shareholder that is an entity be domiciled in the United States and have a valid U.S. taxpayer identification number or be domiciled in a U.S. territory and have a valid U.S. taxpayer identification number or IRS Form W-8.

Table of Contents

The Fund reserves the right to redeem shares in any account that it cannot confirm to its satisfaction is beneficially owned by a natural person, after providing at least 60 days’ advance notice.

Under certain circumstances, if no activity occurs in an account within a time period specified by state law, a shareholder’s shares in the Fund may be transferred to that state.

Persons who were shareholders of an investment portfolio of the Compass Capital Group of Funds in 1996 at the time the portfolio combined with The PNC ^® Fund may purchase and redeem Service Shares of the same fund and for the same account in which they held shares on that date through the procedures described in this section.

How to Sell Shares

	Your Choices	Important Information for You to Know
Full or Partial Redemption of Shares	Have your Financial Intermediary submit your sales order	You can make redemption requests through your Financial Intermediary in accordance with the procedures applicable to your accounts. These procedures may vary according to the type of account and the Financial Intermediary involved and customers should consult their Financial Intermediary in this regard. Financial Intermediaries are responsible for transmitting redemption orders and crediting their customers’ accounts with redemption proceeds on a timely basis. Information relating to such redemption services and charges to process a redemption of shares, if any, should be obtained by customers from their Financial Intermediaries. Financial Intermediaries may place redemption orders by telephoning (800) 537-4942. The price of your shares is based on the next calculation of the Fund’s NAV after your order is placed. For your redemption request to be priced at the NAV on the day of your request, you must submit your request to your Financial Intermediary prior to that day’s close of business on the Exchange (generally 4:00 p.m. Eastern time). Certain Financial Intermediaries, however, may require submission of orders prior to that time. Any redemption request placed after that time will be priced at the NAV at the close of business on the next business day. Financial Intermediaries may charge a fee to process a redemption of shares. Shareholders should indicate which class of shares they are redeeming. The Fund may reject an order to sell shares under certain circumstances.
	Selling shares held directly with BlackRock	Methods of Redeeming Redeem by Telephone: Shareholders may place redemption orders by telephoning (800) 537-4942. The Fund, its administrators and the Distributor will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. The Fund and its service providers will not be liable for any loss, liability, cost or expense for acting upon telephone instructions that are reasonably believed to be genuine in accordance with such procedures. The Fund may refuse a telephone redemption request if it believes it is advisable to do so. During periods of substantial economic or market change, telephone redemptions may be difficult to complete. Please find below alternative redemption methods.

Table of Contents

	Your Choices	Important Information for You to Know
Full or Partial Redemption of Shares (continued)	Selling shares held directly with BlackRock (continued)	Redeem by Internet: You may redeem in your account, by logging onto the BlackRock website at www.blackrock.com. Proceeds from Internet redemptions will be sent via wire to the bank account of record. Redeem in Writing: Redemption requests may be sent in proper form to BlackRock Funds, P.O. Box 9819, Providence, RI 02940-8019, or for overnight delivery, 4400 Computer Drive, Westborough, Massachusetts 01588. Under certain circumstances, a medallion signature guarantee will be required. Payment of Redemption Proceeds Redemption proceeds may be paid by check or, if the Fund has verified banking information on file, by wire transfer. Payment by Check: BlackRock will typically mail redemption proceeds one business day following receipt of a properly completed request, but in any event, within seven days. Shares can be redeemed by telephone and the proceeds sent by check to the shareholder at the address on record. Shareholders will pay $15 for redemption proceeds sent by check via overnight mail. You are responsible for any additional charges imposed by your bank for this service. The Fund reserves the right to reinvest any dividend or distribution amounts (e.g., income dividends or capital gains) which you have elected to receive by check should your check be returned as undeliverable or remain uncashed for more than 6 months. No interest will accrue on amounts represented by uncashed checks. Your check will be reinvested in your account at the NAV next calculated, on the day of the investment. When reinvested, those amounts are subject to the risk of loss like any fund investment. If you elect to receive distributions in cash and a check remains undeliverable or uncashed for more than 6 months, your cash election may also be changed automatically to reinvest and your future dividend and capital gains distributions will be reinvested in the Fund at the NAV as of the date of payment of the distribution. Payment by Wire Transfer: Proceeds for redeemed shares for which a redemption order is received before 4:00 p.m. (Eastern time) on a business day are normally paid in Federal funds wired to the redeeming shareholder on the same business day, provided that the Fund’s custodian is also open for business. Proceeds for redemption orders received on a day when the Fund’s custodian is closed are normally wired in Federal funds on the next business day following redemption on which the Fund’s custodian is open for business. The Fund reserves the right to wire redemption proceeds within seven days after receiving a redemption order if, in the judgment of the Fund, an earlier payment could adversely affect the Fund. Shares can be redeemed by Federal wire transfer to a single previously designated bank account. No charge for wiring redemption proceeds with respect to Service Shares is imposed by the Fund, although Financial Intermediaries may charge their customers for redemption services. Information relating to such redemption services and charges, if any, should be obtained by customers from their Financial Intermediaries. You are responsible for any additional charges imposed by your bank for wire transfers. The Fund is not responsible for the efficiency of the Federal wire system or the shareholder’s firm or bank. To change the name of the single, designated bank account to receive wire redemption proceeds, it is necessary to send a written request to the Fund at the address on the back cover of this prospectus. *** If you make a redemption request before the Fund has collected payment for the purchase of shares, the Fund may delay mailing your proceeds. This delay will usually not exceed ten days. Please see “Account Information — Liquidity Fees and Redemption Gates” for more information.

BlackRock has contractually agreed to cap net expenses (excluding: (i) interest, taxes, dividends tied to short sales, brokerage commissions, and other expenditures which are capitalized in accordance with generally accepted accounting principles; (ii) expenses incurred directly or indirectly by the Fund as a result of investments in other investment companies and pooled investment vehicles; (iii) other expenses attributable to, and incurred as a result of, the Fund’s investments; and (iv) other extraordinary expenses not incurred in the ordinary course of the Fund’s business, if any) of Service Shares of the Fund at the levels shown below and in the Fund’s fees and expenses table in the “Fund Overview” section. Items (i), (ii), (iii) and (iv) in the preceding sentence are referred to in this prospectus as “Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses.” To achieve this expense cap, BlackRock has agreed to waive and/or reimburse fees or expenses if these operating expenses exceed a certain limit.

With respect to the Fund, BlackRock has contractually agreed to waive and/or reimburse fees or expenses in order to limit Total Annual Fund Operating Expenses to the amount noted in the table below.

	Contractual Cap ¹ on Total Annual Operating Expenses ² (excluding Dividend Expense, Interest Expense, Acquired Fund Fees and Expenses and certain other Fund expenses)
Service Shares	0.50%

¹	The contractual cap is in effect through July 31, 2018. The contractual 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.
²	As a percentage of average daily net assets.

Table of Contents

(a) the amount of fees waived or expenses reimbursed during those prior two fiscal years under the agreement and (b) the amount by which the expense limit for that share class exceeds the operating expenses of the share class for the current fiscal year, provided that (i) the Fund of which the share class is a part has more than $50 million in assets and (ii) BlackRock or an affiliate serves as the Fund’s manager or administrator. This repayment applies only to the contractual caps on net expenses and does not apply to any voluntary waivers that may be in effect from time to time. The Fund may only make repayments to BlackRock of amounts waived and/or reimbursed by BlackRock if such repayments do not cause the Fund’s net expense ratio, taking into account such repayments, to exceed either: (i) the Fund’s expense cap in place at the time such waivers and/or reimbursements were made; or (ii) the Fund’s current expense cap at the time of such repayment.

For the fiscal year ended March 31, 2017, the Fund paid BlackRock aggregate management fees, net of any applicable waivers, equal to 0.12% of the Fund’s average daily net assets.

Conflicts of Interest

Table of Contents

brokerage and other payments to Affiliates in connection with the Fund’s portfolio investment transactions. An Affiliate may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund. This may include transactions in securities issued by other open-end and closed-end investment companies (which may include investment companies that are affiliated with the Fund and BlackRock, to the extent permitted under the Investment Company Act). The trading activities of these Affiliates are carried out without reference to positions held directly or indirectly by the Fund and may result in an Affiliate having positions in certain securities that are senior or junior to, or have interests different from or adverse to, the securities that are owned by the Fund.

Valuation of Fund Investments

A mutual fund is a pool of investors’ money that is used to purchase a portfolio of securities, which in turn is owned in common by the investors. Investors put money into a mutual fund by buying shares. If a mutual fund has a portfolio worth $5 million and has 5 million shares outstanding, the NAV per share is $1.00. When you buy Service Shares you pay the NAV per share. Although the Fund seeks to maintain an NAV of $1.00 per share, there is no guarantee it will be able to do so.

The Fund’s investments are valued based on the amortized cost method described in the SAI.

The Transfer Agent will probably receive your order from your registered representative, who takes your order. However, you can also fill out a purchase application and mail it to the Transfer Agent with your check. Please call (800) 537-4942 for a purchase application. Purchase orders received by the Transfer Agent before 4:00 p.m. (Eastern time) on each business day will be priced based on the next NAV calculated on that day, and if you send your payment by Federal funds or other immediately available funds no later than the close of the federal funds wire (normally 6:00 p.m. (Eastern time)) you will receive that day’s dividends.

Table of Contents

Dividends, Distributions and Taxes

BUYING A DIVIDEND

Distributions of net investment income derived by the Fund, if any, are declared daily and paid at least monthly and net realized capital gains, if any, will be distributed at least annually. Dividends will be reinvested automatically in the form of additional shares of the same class of the Fund at NAV unless you instruct the Transfer Agent in writing to pay them in cash. Dividends that are declared but unpaid will remain in the gross assets of the Fund and will, therefore, continue to earn income for the Fund's shareholders. Shareholders redeeming their shares will receive all dividends declared through the date immediately preceding the date of redemption. The Fund anticipates that a significant amount of the distributions may be taxed as ordinary income, although the Fund may distribute capital gains as well. Capital gains may be taxable to you at different rates depending on how long the Fund held the assets sold.

Financial Highlights

The Financial Highlights table is intended to help you understand the Fund’s financial performance for the periods shown. Certain information reflects the financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned or lost on an investment in the Fund (assuming reinvestment of all dividends and/or distributions). The information has been audited by Deloitte & Touche LLP, whose report, along with the Fund’s financial statements, is included in the Fund’s Annual Report, which is available upon request.

determined by BlackRock, the Fund’s investment manager, pursuant to guidelines approved by the Trust’s Board of Trustees (the “Board”).

Principal Risks of Investing in the Fund

The following is a summary description of principal risks of investing in the Fund.

■

■	Extension Risk — When interest rates rise, certain obligations will be paid off by the obligor more slowly than anticipated, causing the value of these securities to fall.

■

	The profitability of many types of financial services companies may be adversely affected in certain market cycles, including periods of rising interest rates, which may restrict the availability and increase the cost of capital, and declining economic conditions, which may cause credit losses due to financial difficulties of borrowers. Because many types of financial services companies are vulnerable to these economic cycles, a large portion of the Fund’s investments may lose value during such periods.
■	Foreign Exposure Risk — Securities issued or supported by foreign entities, including foreign banks and corporations, may involve additional risks and considerations. Extensive public information about the foreign issuer may not be available, and unfavorable political, economic or governmental developments in the foreign country involved could affect the payment of principal and interest.
■	Income Risk — Income risk is the risk that the Fund’s yield will vary as short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates.
■	Interest Rate Risk — Interest rate risk is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter-term securities. Due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund.
■	Liquidity Fee and Redemption Gate Risk — The Board has discretion to impose a liquidity fee of up to 2% upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. Accordingly, you may not be able to sell your shares or your redemptions may be subject to a liquidity fee when you sell your shares at certain times.
■	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

Table of Contents

	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.
■	Prepayment Risk — When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields.
■	Repurchase Agreements and Purchase and Sale Contracts Risk — If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the Fund may lose money.
■	Stable Net Asset Value Risk — The Fund may not be able to maintain a stable NAV of $1.00 per share at all times. If the Fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), the Fund, along with other money market funds, could be subject to increased redemption activity.
■	U.S. Government Obligations Risk — Certain securities in which the Fund may invest, including securities issued by certain U.S. Government agencies and U.S. Government sponsored enterprises, are not guaranteed by the U.S. Government or supported by the full faith and credit of the United States.
■	Variable and Floating Rate Instrument Risk — The absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults.
■	When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Details About the Fund

How the Fund Invests

The Fund is a retail money market fund managed pursuant to Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

■	The Fund seeks to maintain a net asset value (“NAV”) of $1.00 per share.
■	The Fund will maintain a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life of 120 days or less. For a discussion of dollar-weighted average maturity and dollar-weighted average life, please see the Glossary on page 25.
■	Pursuant to Rule 2a-7, the Fund is subject to a “general liquidity requirement” that requires that the Fund hold securities that are sufficiently liquid to meet reasonably foreseeable shareholder redemptions in light of its obligations under Section 22(e) of the Investment Company Act regarding share redemptions and any commitments the Fund has made to shareholders. To comply with this general liquidity requirement, BlackRock Advisors, LLC (“BlackRock”) must consider factors that could affect the Fund’s liquidity needs, including characteristics of the Fund’s investors and their likely redemptions. Depending upon the volatility of its cash flows (particularly shareholder redemptions), this may require the Fund to maintain greater liquidity than would be required by the weekly minimum liquidity requirement discussed below.
■	The Fund will not acquire any illiquid security ( i.e. , securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund) if, immediately following such purchase, more than 5% of the Fund’s total assets are invested in illiquid securities. The Fund will not acquire any security other than a daily liquid asset unless, immediately following such purchase, at least 10% of its total assets would be invested in daily liquid assets, and the Fund will not acquire any security other than a weekly liquid asset unless, immediately following such purchase, at least 30% of its total assets would be invested in weekly liquid assets. For a discussion of daily liquid assets and weekly liquid assets, please see the Glossary on page 25.
■	The Fund invests in securities maturing within 13 months or less from the date of purchase, with certain exceptions. For example, certain government securities held by the Fund may have remaining maturities exceeding 13 months if such securities provide for adjustments in their interest rates not less frequently than every 13 months.
■	The securities purchased by the Fund are subject to the quality, diversification, and other requirements of Rule 2a-7, and other rules of the Securities and Exchange Commission (the “SEC”). The Fund will purchase securities (or issuers of such securities) that are Eligible Securities that present minimal credit risk as determined by BlackRock pursuant to guidelines approved by the Trust’s Board of Trustees (the “Board”). For a discussion of Eligible Securities, please see the Glossary on page 25.

Investment Objective

The investment objective of the Fund is to seek as high a level of current income as is consistent with maintaining liquidity and stability of principal.

Table of Contents

Principal Investment Strategies

■	U.S. dollar-denominated obligations issued or supported by the credit of U.S. or foreign banks or savings institutions with total assets of more than $1 billion (including obligations of foreign branches of such banks)

■

■	Unrated notes, paper and other instruments that are determined by Fund management to be of comparable quality to the instruments described above
■	Asset-backed securities (including interests in “pools” of assets such as mortgages, installment purchase obligations and credit card receivables)
■	Securities issued or guaranteed by the U.S. Government or by its agencies or authorities
■	Dollar-denominated securities issued or guaranteed by foreign governments or their political subdivisions, agencies or authorities
■	Repurchase agreements relating to the above instruments

Other Strategies

In addition to the principal strategies discussed above, the Fund may also invest or engage in the following investments/strategies:

■	Investment Company Securities — The Fund may invest in securities issued by other open-end or closed-end investment companies as permitted by the Investment Company Act. A pro rata portion of the other investment companies’ expenses may be borne by the Fund’s shareholders. These investments may include, as consistent with the Fund’s investment objective and policies, certain variable rate demand securities issued by closed-end funds, which invest primarily in portfolios of taxable or tax-exempt securities. It is anticipated that the payments made on the variable rate demand securities issued by closed-end municipal bond funds will be exempt from federal income tax.
■	Uninvested Cash Reserves — The Fund may hold up to 20% of its assets in uninvested cash reserves. Uninvested cash reserves will not earn income.
■	U.S. Treasury Floating Rate Notes — The Fund may invest in U.S. Treasury Floating Rate Notes (FRNs). These are two-year notes issued by the U.S. Treasury that reset their interest rates on a weekly basis. At maturity, the face value of an FRN is paid to the note holder.

Investment Risks

Table of Contents

the Fund at any time.

The following is a description of certain risks of investing in the Fund.

Principal Risks of Investing in the Fund

■	Asset-Backed Securities Risk — Asset-backed securities represent interests in “pools” of assets, including consumer loans or receivables held in trust. Asset-backed securities, like traditional fixed-income securities, are subject to credit, interest rate, prepayment and extension risks.
	The Fund’s investments in asset-backed securities are subject to additional risks associated with the nature of the assets and the servicing of those assets. These securities also are subject to the risk of default on the underlying assets, particularly during periods of economic downturn.
	Asset-backed securities entail further risks, including the risk that, in certain states, it may be difficult to perfect the liens securing the collateral backing certain asset-backed securities. In addition, certain asset-backed securities are based on loans that are unsecured, which means that there is no collateral to seize if the underlying borrower defaults.
■	Credit Risk — Credit risk refers to the possibility that the issuer of a security will not be able to make principal and interest payments 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. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation.

■

■	Foreign Exposure Risk — Securities issued or supported by foreign entities, including foreign banks and corporations, may involve additional risks and considerations. Extensive public information about the foreign issuer may not be available, and unfavorable political, economic or governmental developments in the foreign country involved could affect the payment of principal and interest.
■	Income Risk — The Fund’s yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in securities with different interest rates.
■	Interest Rate Risk — Interest rate risk is the risk that the value of a debt security may fall when interest rates rise. In general, the market price of debt securities with longer maturities will go up or down more in response to changes in interest rates than the market price of shorter-term securities. Due to fluctuations in interest rates, the market value of such securities may vary during the period shareholders own shares of the Fund.
■	Liquidity Fee and Redemption Gate Risk — The Board has discretion to impose a liquidity fee of up to 2% upon sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. Accordingly, you may not be able to sell your shares or your redemptions may be subject to a liquidity fee when you sell your shares at certain times.
■	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

Table of Contents

	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.
■	Prepayment Risk — When interest rates fall, certain obligations will be paid off by the obligor more quickly than originally anticipated, and the Fund may have to invest the proceeds in securities with lower yields. In periods of falling interest rates, the rate of prepayments tends to increase (as does price fluctuation) as borrowers are motivated to pay off debt and refinance at new lower rates. During such periods, reinvestment of the prepayment proceeds by the management team will generally be at lower rates of return than the return on the assets that were prepaid. Prepayment reduces the yield to maturity and the average life of the security.
■	Repurchase Agreements and Purchase and Sale Contracts Risk — If the other party to a repurchase agreement or purchase and sale contract defaults on its obligation under the agreement, the Fund may suffer delays and incur costs or lose money in exercising its rights under the agreement. If the seller fails to repurchase the security in either situation and the market value of the security declines, the Fund may lose money.
■	Stable Net Asset Value Risk — The Fund may not be able to maintain a stable NAV of $1.00 per share at all times. If the Fund fails to maintain a stable NAV (or if there is a perceived threat of such a failure), the Fund, along with other money market funds, could be subject to increased redemption activity.
■	U.S. Government Obligations Risk — Not all U.S. Government securities are backed by the full faith and credit of the United States. Obligations of certain agencies, authorities, instrumentalities and sponsored enterprises of the U.S. Government are backed by the full faith and credit of the United States ( e.g ., the Government National Mortgage Association); other obligations are backed by the right of the issuer to borrow from the U.S. Treasury ( e.g ., the Federal Home Loan Banks) and others are supported by the discretionary authority of the U.S. Government to purchase an agency’s obligations. Still others are backed only by the credit of the agency, authority, instrumentality or sponsored enterprise issuing the obligation. No assurance can be given that the U.S. Government would provide financial support to any of these entities if it is not obligated to do so by law.
■	Variable and Floating Rate Instrument Risk — The absence of an active market for these securities could make it difficult for the Fund to dispose of them if the issuer defaults.
■	When-Issued and Delayed Delivery Securities and Forward Commitments Risk — When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.

Other Risks of Investing in the Fund

The Fund may also be subject to certain other risks associated with its investments and investment strategies, including:

■

■	Liquidity Risk — Liquidity risk refers to the possibility that it may be difficult or impossible to sell certain positions at an acceptable price.

Account Information

How to Choose the Share Class that Best Suits Your Needs

The Fund currently offers multiple share classes (Service Shares offered through Westcore in this prospectus), allowing you to invest in the way that best suits your needs. Each share class represents the same ownership interest in the portfolio investments of the Fund. When you choose your class of shares, you should consider the size of your investment and how long you plan to hold your shares. Your Westcore representative can help you determine which share class is best suited to your personal financial goals.

The Fund’s shares are distributed by BlackRock Investments, LLC (the “Distributor”), an affiliate of BlackRock.

The table below summarizes key features of the Service Share class of the Fund.

Service Shares at a Glance


Availability	Limited to certain investors whose beneficial owner is a natural person, including: financial intermediaries (such as banks and brokerage firms) acting on behalf of their customers, certain persons who were shareholders of the Compass Capital Group of Funds at the time of its combination with The PNC ^® Fund in 1996 and investors that participate in the Capital Directions ^SM asset allocation program. Service Shares will normally be held by financial intermediaries or in the name of nominees of financial intermediaries on behalf of their customers. Service Shares are normally purchased through a customer’s account at a financial intermediary through procedures established by such financial intermediary. In these cases, confirmation of share purchases and redemptions will be sent to the financial intermediaries. A customer’s ownership of shares will be recorded by the financial intermediary and reflected in the account statements provided by such financial intermediaries to their customers. Investors wishing to purchase Service Shares should contact their financial intermediaries.
Minimum Investment	$5,000. However, financial intermediaries may set a higher minimum for their customers.
Initial Sales Charge?	No. Entire purchase price is invested in shares of the Fund.
Deferred Sales Charge?	No.
Service and Distribution Fees?	No Distribution Fee. 0.25% Annual Service Fee.
Redemption Fees?	The Fund may impose a liquidity fee under certain limited circumstances. See “Liquidity Fees and Redemption Gates” below.
Advantage	No up-front sales charge so you start off owning more shares.
Disadvantage	Limited availability.

Distribution and Shareholder Servicing Payments

Plan Payments

The shareholder servicing fees payable pursuant to the Plan are paid to compensate brokers, dealers, financial institutions and industry professionals (including BlackRock and The PNC Financial Services Group, Inc. (“PNC”) and their respective affiliates) (each, a “Financial Intermediary”) for providing support services to their customers who own Service Shares, including responding to customer questions on the services performed by the Financial Intermediary and investments in Service Shares, assisting customers in choosing and changing dividend options, account designations and addresses and providing other similar shareholder liaison services. Because the fees paid by the

Table of Contents

Fund under the Plan are paid out of the Fund’s assets on an ongoing basis, over time these fees will increase the cost of your investment in the Service Shares of the Fund and may cost you more than paying other types of sales charges.

Other Payments by the Fund

Other Payments by BlackRock

Please contact your Financial Intermediary for details about payments it may receive from the Fund or from BlackRock, the Fund’s distributor or their affiliates. For more information, see the SAI.

How to Buy and Sell Shares

The chart on the following pages summarizes how to buy and sell shares through Westcore. Because the selection of a mutual fund involves many considerations, Westcore may help you with this decision.

With certain limited exceptions, the Fund is generally available only to investors residing in the United States and may not be distributed by a foreign Financial Intermediary. Under this policy, in order to accept new accounts or additional investments into existing accounts, the Fund generally requires that (i) a shareholder that is a natural person be a U.S. citizen or resident alien, in each case residing within the United States or a U.S. territory (including APO/FPO/DPO addresses), and have a valid U.S. taxpayer identification number, and (ii) a Financial Intermediary or a shareholder that is an entity be domiciled in the United States and have a valid U.S. taxpayer identification number or be domiciled in a U.S. territory and have a valid U.S. taxpayer identification number or IRS Form W-8. Any existing account that is updated to reflect a non-U.S. address will also be restricted from making additional investments.

The Fund reserves the right to redeem shares in any account that it cannot confirm to its satisfaction is beneficially owned by a natural person, after providing at least 60 days’ advance notice.

Table of Contents

Under certain circumstances, if no activity occurs in an account within a time period specified by state law, a shareholder’s shares in the Fund may be transferred to that state.

How to Buy Shares

	Your Choices	Important Information for You to Know
Initial Purchase	Determine the amount of your investment	Refer to the minimum initial investment in the “Service Shares at a Glance” table of this prospectus.
	Have your Financial Intermediary submit your purchase order	A mutual fund is a pool of investors’ money that is used to purchase a portfolio of securities, which in turn is owned in common by the investors. Investors put money into a mutual fund by buying shares. If a mutual fund has a portfolio worth $5 million and has 5 million shares outstanding, the NAV per share is $1.00. Although the Fund seeks to maintain an NAV of $1.00 per share, there is no guarantee it will be able to do so. The price of your shares is based on the next calculation of the Fund’s NAV after your order is placed. Any purchase orders placed prior to the close of business on the New York Stock Exchange (the “Exchange”) (generally 4:00 p.m. Eastern time) will be priced at the NAV determined that day. Certain Financial Intermediaries, however, may require submission of orders prior to that time. The Fund’s investments are valued based on the amortized cost method described in the SAI. Service Shares are sold at the NAV per share determined after an order is received by the Fund’s transfer agent, BNY Mellon Investment Servicing (US) Inc. (the “Transfer Agent”). You may place a purchase order for the Fund by telephoning the Fund at (800) 392- CORE (2673) before 12:30 p.m. (Eastern time) on a day both the Exchange and the Federal Reserve Bank of Philadelphia are open (each, a “business day”). If your order is received before 12:30 p.m. (Eastern time) on a day both the Exchange and the Federal Reserve Bank of Philadelphia are open, it will be executed at 12:30 p.m. (Eastern time). If payment for an order is not received by 4:00 p.m. (Eastern time), the order will be cancelled. You will be informed if this should happen. No orders will be accepted after 12:30 p.m. (Eastern time). NAV is calculated separately for each class of shares of the Fund as of the close of business on the Exchange, generally 4:00 p.m. (Eastern time), each day both the Exchange and the Federal Reserve Bank of Philadelphia are open. Shares will not be priced on days the Exchange or the Federal Reserve Bank of Philadelphia are closed. The Fund may elect, in its discretion if it is determined to be in shareholders’ best interest, to be open on days when the Exchange is closed due to an emergency. The Fund may reject any order to buy shares and may suspend the sale of shares at any time, including when a redemption gate is in place (see “Account Information — Liquidity Fees and Redemption Gates” below).
Add to Your Investment	Purchase additional shares	There is no minimum amount for additional investments.
	Have your Financial Intermediary submit your purchase order for additional shares	To purchase additional shares you may contact Westcore Investor Service at (800) 392-CORE (2673).
	Acquire additional shares by reinvesting dividends and capital gains	All dividends and capital gains distributions are automatically reinvested without a sales charge. To make any changes to your dividend and/or capital gains distributions options, please call Westcore Investor Service at (800) 392-CORE (2673).

Table of Contents

	Your Choices	Important Information for You to Know
How to Pay for Shares	Making payment for purchases	Payment for Service Shares must normally be made in Federal funds or other immediately available funds by your Financial Intermediary but in no event later than 4:00 p.m. (Eastern time) on the day your order is accepted. Payment may also, at the discretion of the Trust, be made in the form of securities that are permissible investments for the Fund. If payment is not received by this time, the order will be canceled and you and your Financial Intermediary will be responsible for any loss to the Fund.

How to Sell Shares

	Your Choices	Important Information for You to Know
Full or Partial Redemption of Shares	Have your Financial Intermediary submit your sales order	Customers of institutions may redeem Service Shares in accordance with the procedures applicable to their accounts with the institutions. These procedures will vary according to the type of account and the institution involved and customers should consult their account managers in this regard. Institutions are responsible for transmitting redemption orders and crediting their customers’ accounts with redemption proceeds on a timely basis. Institutions may place redemption orders by telephoning Westcore Investor Service at (800) 392-CORE (2673). Shares are redeemed at NAV per share next determined after receipt of the redemption order. Westcore Investor Service and/or the Distributor will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. The Fund and its service providers will not be liable for any loss, liability, cost or expense for acting upon telephone instructions that are reasonably believed to be genuine in accordance with such procedures. Proceeds for redeemed shares for which a redemption order is received before 12:30 p.m. (Eastern time) on a business day are normally paid in Federal funds wired to the redeeming institution on the same business day, provided that the Fund’s custodian is also open for business. Proceeds for redemption orders received between 12:30 p.m. (Eastern time) and 4:00 p.m. (Eastern time) or on a day when the Fund’s custodian is closed are normally wired in Federal funds on the next business day following redemption on which the Fund’s custodian is open for business. The Fund reserves the right to reinvest any dividend or distribution amounts (e.g., income dividends or capital gains) which you have elected to receive by check should your check be returned as undeliverable or remain uncashed for more than 6 months. No interest will accrue on amounts represented by uncashed checks. Your check will be reinvested in your account at the NAV next calculated, on the day of the investment. When reinvested, those amounts are subject to the risk of loss like any fund investment. If you elect to receive distributions in cash and a check remains undeliverable or uncashed for more than 6 months, your cash election may also be changed automatically to reinvest and your future dividend and capital gains distributions will be reinvested in the Fund at the NAV as of the date of payment of the distribution. The Fund reserves the right to wire redemption proceeds within seven days after receiving a redemption order if, in the judgment of the Fund, an earlier payment could adversely affect the Fund. No charge for wiring redemption payments is imposed by the Fund, although institutions may charge their customer accounts for redemption services. Information relating to such redemption services and charges, if any, should be obtained by customers from their institutions. During periods of substantial economic or market change, telephone redemptions may be difficult to complete. Redemption requests may also be mailed to Westcore Funds, P.O. Box 44323 Denver, CO 80201. The Fund is not responsible for the efficiency of the Federal wire system or the shareholder’s firm or bank. The Fund does not currently

	Your Choices	Important Information for You to Know
Full or Partial Redemption of Shares (continued)	Have your Financial Intermediary submit your sales order (continued)	charge for wire transfers. The shareholder is responsible for any charges imposed by the shareholder’s bank. To change the name of the single, designated bank account to receive wire redemption proceeds, it is necessary to send a written request to Westcore Funds, P.O. Box 44323, Denver, CO 80201. The Fund or Westcore may refuse a telephone redemption request if it believes it is advisable to do so. Under normal and stressed market conditions, the Fund typically expects to meet redemption requests by using cash or cash equivalents in its portfolio or by selling portfolio assets to generate additional cash. Please see “Account Information — Liquidity Fees and Redemption Gates” for more information.

Fund’s Rights

The Fund may:

■	Suspend the right of redemption if trading is halted or restricted on the Exchange or under other emergency conditions described in the Investment Company Act;

■	Redeem shares for property other than cash as may be permitted under the Investment Company Act; and
■	Redeem shares involuntarily in certain cases, such as when the value of a shareholder account falls below a specified level or if the Fund does not believe the account is for a natural person.

Liquidity Fees and Redemption Gates

■	30% weekly liquid assets — If the weekly liquid assets of the Fund fall below 30% of the Fund’s total assets, and the Board determines it is in the best interests of the Fund, the Board may impose at any time, and as early as the same day, a liquidity fee of up to 2% of the amount redeemed, or a redemption gate that temporarily suspends the right of redemption.
■	10% weekly liquid assets — If the weekly liquid assets of the Fund fall below 10% of the Fund’s total assets as of the end of a business day, the Board will impose, at the beginning of the next business day, a liquidity fee of 1% of

Valuation of Fund Investments

A mutual fund is a pool of investors’ money that is used to purchase a portfolio of securities, which in turn is owned in common by the investors. Investors put money into a mutual fund by buying shares. If a mutual fund has a portfolio worth $5 million and has 5 million shares outstanding, the NAV per share is $1.00. When you buy Service Shares you pay the NAV per share. Although the Fund seeks to maintain an NAV of $1.00 per share, there is no guarantee it will be able to do so.

The Fund’s investments are valued based on the amortized cost method described in the SAI.

The Transfer Agent will probably receive your order from your registered representative, who takes your order. However, you can also fill out a purchase application and mail it to the Transfer Agent with your check. Please call (800) 392-CORE (2673) for a purchase application. Purchase orders received by the Transfer Agent before 12:30 p.m. (Eastern time) on each business day will be priced based on the next NAV calculated on that day, and shareholders will receive dividends for that day.

SUPPLEMENTAL INSTRUCTIONS FOR WESTCORE INVESTORS

PURCHASES, REDEMPTIONS & EXCHANGES (Continued from inside cover)

Wire, Telephone, and Exchange Procedures:

Wire purchases, telephone redemptions and exchanges will be processed at the net asset value determination next occurring after your order is received and accepted by Westcore. An order will not be accepted unless payment is received by Westcore in acceptable form and in sufficient time to reasonably allow for entry of the order before such determination. An order may not be accepted if a redemption gate or liquidity fee are in place. Purchases by wire may be accepted only for existing accounts. Investors redeeming by wire may be charged a wire fee by their financial institution. Wire redemption proceeds are generally transmitted by Westcore to Westcore investors on the next business day following the date of redemption. Exchanges into a Westcore fund will be processed at Westcore’s net asset value determination next occurring after the net asset value determination time when your money market fund account is processed. Exchanges into your money market fund account will be processed at the Money Market Portfolio’s net asset value determination next occurring after your Westcore account is processed. Please call 800.392.CORE (2673) for additional information and instructions regarding wire purchase, telephone redemption, and exchange procedures.

Automated Transactions:

You may place transactions or access your account automatically through the Westcore Trans@ction Center located at www.westcore.com or through the Westcore Automated Service Line at 800.392.CORE (2673).

Annual Small Balance Account Maintenance Fee: Westcore Funds may deduct an annual maintenance fee of $12 from accounts serviced directly by Westcore Funds with a value less than $750. It is expected that accounts will be valued for the purpose of calculating this maintenance fee on the first Friday of December each year. The fee is designed to offset in part the relatively higher costs of servicing smaller accounts. This fee will not be deducted from accounts with an automatic investment plan or from accounts of shareholders who have a total of $10,000 or more invested directly with Westcore in multiple accounts (multiple accounts must have the same Social Security number to qualify).

Shareholder Reports:

Westcore Funds will deliver a single copy of the Money Market Portfolio’s financial reports and prospectuses to multiple investors with the same mailing address. Shareholders who desire individual copies of such reports or prospectuses should call 800.392.CORE (2673) or write to us at Westcore Funds, P.O. Box 44323, Denver, CO 80201.

PART I : INFORMATION ABOUT BLACKROCK MONEY MARKET PORTFOLIO

Part I of this Statement of Additional Information (“SAI”) sets forth information about BlackRock Money Market Portfolio (“Money Market Portfolio” or the “Fund”), a series of BlackRock Funds ^SM (the “Trust”). It includes information about the Trust’s Board of Trustees (the “Board”), the advisory and management services provided to and the management fees paid by the Fund and information about other fees applicable to and services provided to the Fund. This Part I of this SAI should be read in conjunction with the Fund’s Prospectus and those portions of Part II of this SAI that pertain to the Fund.

The Fund is a retail money market fund under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), which means it has policies and procedures reasonably designed to limit all beneficial owners of the Fund to natural persons.

I. Investment Objective and Policies

Please see the section “Details About the Fund — How the Fund Invests” in the Fund’s Prospectus for information about the Fund’s investment objective and policies. Additional information regarding the Fund’s investment objective and policies is included below.

The Fund’s manager is BlackRock Advisors, LLC (“BlackRock” or the “Manager”).

Additional Information on Investment Strategies

The Fund may invest in a broad range of short-term, high quality, U.S. dollar-denominated instruments, such as government, bank, commercial and other obligations that are available in the money markets. In particular, the Fund may invest in:

(a) U.S. dollar-denominated obligations issued or supported by the credit of U.S. or non-U.S. banks or savings institutions with total assets in excess of $1 billion (including obligations of non-U.S. branches of such banks);

(b) high quality commercial paper and other obligations issued or guaranteed by U.S. and non-U.S. corporations and other issuers rated (at the time of purchase) A-2 or higher by S&P Global Ratings (“S&P”), P-2 (Prime-2) or higher by Moody’s Investors Service, Inc. (“Moody’s”) or F2 or higher by Fitch Ratings, Inc. (“Fitch”), as well as high quality corporate bonds rated (at the time of purchase) A or higher by those rating agencies;

(c) unrated notes, paper and other instruments that are of comparable quality to the instruments described in (b) above as determined by BlackRock;

(d) asset-backed securities (including interests in “pools” of assets such as mortgages, installment purchase obligations and credit card receivables);

(e) securities issued or guaranteed as to principal and interest by the U.S. Government or by its agencies or authorities and related custodial receipts;

(f) dollar-denominated securities issued or guaranteed by non-U.S. governments or their political subdivisions, agencies or authorities;

(g) funding agreements issued by highly-rated U.S. insurance companies;

(h) securities issued or guaranteed by state or local governmental bodies;

(i) repurchase agreements relating to the above instruments; and

(j) municipal bonds and notes whose principal and interest payments are guaranteed by the U.S. Government or one of its agencies or authorities or which otherwise depend on the credit of the U.S.

All securities acquired by the Fund will be determined at the time of purchase by BlackRock, under guidelines established by the Board, to present minimal credit risks and will be “Eligible Securities” as defined by the Securities and Exchange Commission (“Commission”). An “Eligible Security” is a security:

1. With a remaining maturity of 397 calendar days or less (with certain exceptions) that BlackRock determines presents minimal credit risks to the Fund after considering certain factors, which must include an analysis of the capacity of the security’s issuer or guarantor to meet its financial obligations, which analysis

I-1

must include, to the extent appropriate, consideration of the following factors with respect to the security’s issuer or guarantor:

•	Financial condition;
•	Sources of liquidity;
•	Ability to react to future market-wide and issuer- or guarantor-specific events, including ability to repay debt in a highly adverse situation; and
•	Strength of the issuer’s or guarantor’s industry within the economy and relative to economic trends, and issuer’s or guarantor’s competitive position within its industry;
	2. That is issued by a registered investment company that is a money market fund; or

Regulation Regarding Derivatives. The Commodity Futures Trading Commission (“CFTC”) subjects advisers to registered investment companies to regulation by the CFTC if a fund that is advised by the investment adviser either

I-2

Table of Contents

(i) invests, directly or indirectly, more than a prescribed level of its liquidation value in CFTC-regulated futures, options and swaps (“CFTC Derivatives”), or (ii) markets itself as providing investment exposure to such instruments. To the extent the Fund uses CFTC Derivatives, it intends to do so below such prescribed levels and will not market itself as a “commodity pool” or a vehicle for trading such instruments. Accordingly, BlackRock has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) pursuant to Rule 4.5 under the CEA. BlackRock is not, therefore, subject to registration or regulation as a “commodity pool operator” under the CEA in respect of the Fund.

II. Investment Restrictions

The Fund has adopted restrictions and policies relating to the investment of the Fund’s assets and its activities. Certain of the restrictions are fundamental policies of the Fund and may not be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities (which for this purpose and under the Investment Company Act means the lesser of (i) 67% of the shares represented at a meeting at which more than 50% of the outstanding shares are represented or (ii) more than 50% of the outstanding shares).

Fundamental Investment Restrictions of the Fund:

1. The Fund may not purchase securities of any one issuer (other than securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities or certificates of deposit for any such securities) if more than 5% of the value of the Fund’s total assets (taken at current value) would be invested in the securities of such issuer, or more than 10% of the issuer’s outstanding voting securities would be owned by the Fund or the Trust, except that up to 25% of the value of the Fund’s total assets (taken at current value) may be invested without regard to these limitations. For purposes of this limitation, a security is considered to be issued by the entity (or entities) whose assets and revenues back the security. A guarantee of a security is not deemed to be a security issued by the guarantor when the value of all securities issued and guaranteed by the guarantor, and owned by the Fund, does not exceed 10% of the value of the Fund’s total assets.

2. The Fund may not borrow money or issue senior securities, except that the Fund may borrow from banks and enter into reverse repurchase agreements for temporary purposes in amounts up to one-third of the value of its total assets at the time of such borrowing; or mortgage, pledge or hypothecate any assets, except in connection with any such borrowing and then in amounts not in excess of one-third of the value of the Fund’s total assets at the time of such borrowing. The Fund will not purchase securities while its aggregate borrowings (including reverse repurchase agreements and borrowings from banks) in excess of 5% of its total assets are outstanding. Securities held in escrow or separate accounts in connection with the Fund’s investment practices are not deemed to be pledged for purposes of this limitation.

3. The Fund may not purchase any securities which would cause, at the time of purchase, less than 25% of the value of its total assets to be invested in the obligations of issuers in the financial services industry, or in obligations, such as repurchase agreements, secured by such obligations (unless the Fund is in a temporary defensive position) or which would cause, at the time of purchase, more than 25% of the value of its total assets to be invested in the obligations of issuers in any other industry. In applying the investment limitations stated in this paragraph, (i) there is no limitation with respect to the purchase of (a) instruments issued (as defined in Investment Limitation number 1 above) or guaranteed by the United States, any state, territory or possession of the United States, the District of Columbia or any of their authorities, agencies, instrumentalities or political subdivisions, (b) instruments issued by domestic banks (which may include U.S. branches of non-U.S. banks) and (c) repurchase agreements secured by the instruments described in clauses (a) and (b); (ii) wholly-owned finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of the parents; and (iii) utilities will be divided according to their services, for example, gas, gas transmission, electric and gas, electric and telephone will each be considered a separate industry.

4. The Fund may not:

a. purchase or sell real estate, except that the Fund may purchase securities of issuers which deal in real estate and may purchase securities which are secured by interests in real estate;

b. acquire any other investment company or investment company security except in connection with a merger, consolidation, reorganization or acquisition of assets or where otherwise permitted by the Investment Company Act;

I-3

Table of Contents

c. act as an underwriter of securities within the meaning of the Securities Act of 1933 except to the extent that the purchase of obligations directly from the issuer thereof, or the disposition of securities, in accordance with the Fund’s investment objective, policies and limitations may be deemed to be underwriting;

d. write or sell put options, call options, straddles, spreads, or any combination thereof, except for transactions in options on securities and securities indices, futures contracts and options on futures contracts;

e. purchase securities of companies for the purpose of exercising control;

f. purchase securities on margin, make short sales of securities or maintain a short position, except that (i) this investment limitation shall not apply to the Fund’s transactions in futures contracts and related options or the Fund’s sale of securities short against the box, and (ii) the Fund may obtain short-term credit as may be necessary for the clearance of purchases and sales of portfolio securities;

g. purchase or sell commodity contracts, or invest in oil, gas or mineral exploration or development programs, except that the Fund may, to the extent appropriate to its investment policies, purchase securities, including publicly traded securities, of companies engaging in whole or in part in such activities and may enter into futures contracts and related options;

h. make loans, except that the Fund may purchase and hold debt instruments and enter into repurchase agreements in accordance with its investment objective and policies and may lend portfolio securities. See “Investment Objectives and Policies” above; or

i. purchase or sell commodities except that the Fund may, to the extent appropriate to its investment policies, purchase securities of companies engaging in whole or in part in such activities, may engage in currency transactions and may enter into futures contracts and related options.

Although the foregoing investment limitations would permit the Fund to invest in options, futures contracts and options on futures contracts, and to sell securities short against the box, the Fund does not currently intend to trade in such instruments or engage in such transactions during the next twelve months (except to the extent a portfolio security may be subject to a “demand feature” or “put” as permitted under Commission regulations for money market funds). Prior to making any such investments, the Fund would notify its shareholders and add appropriate descriptions concerning the instruments and transactions to its Prospectus.

Unless otherwise indicated, all limitations apply only at the time that a transaction is undertaken. Any change in the percentage of the Fund’s assets invested in certain securities or other instruments resulting from market fluctuations or other changes in the Fund’s total assets will not require the Fund to dispose of an investment until the Manager determines that it is practicable to sell or close out the investment without undue market or tax consequences.

III. Information on Trustees and Officers

The Board consists of thirteen individuals (each a “Trustee”), eleven of whom are not “interested persons” of the Trust as defined in the Investment Company Act (the “Independent Trustees”). The registered investment companies advised by BlackRock or its affiliates (the “BlackRock-advised Funds”) are organized into one complex of closed-end funds (the “Closed-End Complex”), two complexes of open-end funds (the “Equity-Liquidity Complex” and the “Equity-Bond Complex”) and one complex of exchange-traded funds (each a “BlackRock Fund Complex”). The Trust is included in the BlackRock Fund Complex referred to as the Equity-Liquidity Complex. The Trustees also oversee as board members the operations of the other open-end registered investment companies included in the Equity-Liquidity Complex.

The Board has overall responsibility for the oversight of the Trust and the Fund. The Chair of the Board is an Independent Trustee, and the Chair of each Board committee (each, a “Committee”) is an Independent Trustee. The Board has five standing Committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight and Contract Committee and an Executive Committee. The role of the Chair of the Board is to preside at all meetings of the Board, and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Chair of each Committee performs a similar role with respect to the Committee. The Chair of the Board or the Chair of a Committee may also perform such other functions as may be delegated by the Board or the Committee from time to time. The Independent Trustees meet regularly outside the presence of the Fund’s management, in executive session or with other service providers to the Fund. The Board has regular meetings five times a year, and may hold special meetings if required before its next regular meeting. Each Committee meets regularly to conduct the oversight functions delegated to that Committee by the Board and reports its findings to the Board. The Board and each standing Committee conduct annual assessments

I-4

Table of Contents

of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and to allocate areas of responsibility among Committees and the full Board to enhance effective oversight.

The Board has engaged the Manager to manage the Fund on a day-to-day basis. The Board is responsible for overseeing the Manager, other service providers, the operations of the Fund and associated risks in accordance with the provisions of the Investment Company Act, state law, other applicable laws, the Trust’s charter, and the Fund’s investment objectives and strategies. The Board reviews, on an ongoing basis, the Fund’s performance, operations, and investment strategies and techniques. The Board also conducts reviews of the Manager and its role in running the operations of the Fund.

Day-to-day risk management with respect to the Fund is the responsibility of the Manager or of sub-advisers or other service providers (depending on the nature of the risk), subject to the supervision of the Manager. The Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by the Manager and the sub-advisers or other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. Risk oversight forms part of the Board’s general oversight of the Fund and is addressed as part of various Board and Committee activities. The Board, directly or through a Committee, also reviews reports from, among others, management, the independent registered public accounting firm for the Fund, sub-advisers, and internal auditors for the investment adviser or its affiliates, as appropriate, regarding risks faced by the Fund and management’s or the service provider’s risk functions. The Committee system facilitates the timely and efficient consideration of matters by the Trustees, and facilitates effective oversight of compliance with legal and regulatory requirements and of the Fund’s activities and associated risks. The Board has appointed a Chief Compliance Officer, who oversees the implementation and testing of the Fund’s compliance program and reports to the Board regarding compliance matters for the Fund and its service providers. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

The members of the Audit Committee (the “Audit Committee”) are Kenneth L. Urish (Chair), Neil A. Cotty, Claire A. Walton and Frederick W. Winter, all of whom are Independent Trustees. The principal responsibilities of the Audit Committee are to approve, and recommend to the full Board for approval, the selection, retention, termination and compensation of the Trust’s independent registered public accounting firm (the “Independent Registered Public Accounting Firm”) and to oversee the Independent Registered Public Accounting Firm’s work. The Audit Committee’s responsibilities include, without limitation, to (1) evaluate the qualifications and independence of the Independent Registered Public Accounting Firm; (2) approve all audit engagement terms and fees for the Fund; (3) review the conduct and results of each independent audit of the Fund’s annual financial statements; (4) review any issues raised by the Independent Registered Public Accounting Firm or Fund management regarding the accounting or financial reporting policies and practices of the Fund and the internal controls of the Fund and certain service providers; (5) oversee the performance of the Fund’s Independent Registered Public Accounting Firm; (6) review and discuss with management and the Fund’s Independent Registered Public Accounting Firm the performance and findings of the Fund’s internal auditors; (7) discuss with Fund management its policies regarding risk assessment and risk management as such matters relate to the Fund’s financial reporting and controls; (8) resolve any disagreements between Fund management and the Independent Registered Public Accounting Firm regarding financial reporting; and (9) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Audit Committee. The Board has adopted a written charter for the Audit Committee. During the fiscal year ended March 31, 2017, the Audit Committee met five times.

The members of the Governance and Nominating Committee (the “Governance Committee”) are Cynthia A. Montgomery (Chair), Susan J. Carter, Collette Chilton and Robert C. Robb, Jr., all of whom are Independent Trustees. The principal responsibilities of the Governance Committee are to (1) identify individuals qualified to serve as Independent Trustees of the Trust and recommend Independent Trustee nominees for election by shareholders or appointment by the Board; (2) advise the Board with respect to Board composition, procedures and committees (other than the Audit Committee); (3) oversee periodic self-assessments of the Board and committees of the Board (other than the Audit Committee); (4) review and make recommendations regarding Independent Trustee compensation; (5) monitor corporate governance matters and develop appropriate recommendations to the Board; (6) act as the administrative committee with respect to Board policies and procedures, committee policies and procedures (other than the Audit Committee) and codes of ethics as they relate to Independent Trustees; and (7) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Governance Committee. The Governance Committee may consider nominations for the office of Trustee made by Fund shareholders as it deems appropriate. Fund shareholders who wish to recommend a nominee should send nominations to the Secretary of the Trust that include biographical information and set forth the qualifications of the

I-5

Table of Contents

proposed nominee. The Board has adopted a written charter for the Governance Committee. During the fiscal year ended March 31, 2017, the Governance Committee met eight times.

The members of the Compliance Committee (the “Compliance Committee”) are Joseph P. Platt (Chair), Neil A. Cotty, Robert C. Robb, Jr. and Claire A. Walton, all of whom are Independent Trustees. The Compliance Committee’s purpose is to assist the Board in fulfilling its responsibility to oversee regulatory and fiduciary compliance matters involving the Trust, the fund-related activities of BlackRock and any sub-adviser and the Trust’s third-party service providers. The Compliance Committee’s responsibilities include, without limitation, to (1) oversee the compliance policies and procedures of the Trust and its service providers and recommend changes or additions to such policies and procedures; (2) review information on and, where appropriate, recommend policies concerning the Trust’s compliance with applicable law; (3) review reports from, oversee the annual performance review of, and make certain recommendations and determinations regarding the Trust’s Chief Compliance Officer (the “CCO”), including determining the amount and structure of the CCO’s compensation and recommending such amount and structure to the full Board for approval and ratification; and (4) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Compliance Committee. The Board has adopted a written charter for the Compliance Committee. During the fiscal year ended March 31, 2017, the Compliance Committee met four times.

The members of the Performance Oversight and Contract Committee (the “Performance Oversight Committee”) are Mark Stalnecker (Chair), Susan J. Carter, Collette Chilton and Frederick W. Winter, all of whom are Independent Trustees. The Performance Oversight Committee’s purpose is to assist the Board in fulfilling its responsibility to oversee the Fund’s investment performance relative to its agreed-upon performance objectives and to assist the Independent Trustees in their consideration of investment advisory agreements. The Performance Oversight Committee’s responsibilities include, without limitation, to (1) review information on, and make recommendations to the full Board in respect of, the Fund’s investment objectives, policies and practices; (2) review information on the Fund’s investment performance; (3) review information on appropriate benchmarks and competitive universes and unusual or exceptional investment matters; (4) review personnel and other resources devoted to management of the Fund and evaluate the nature and quality of information furnished to the Performance Oversight Committee; (5) recommend any required action regarding changes in fundamental and non-fundamental investment policies and restrictions, fund mergers or liquidations; (6) request and review information on the nature, extent and quality of services provided to the shareholders; (7) make recommendations to the Board concerning the approval or renewal of investment advisory agreements; and (8) undertake such other duties and responsibilities as may from time to time be delegated by the Board to the Performance Oversight Committee. The Board has adopted a written charter for the Performance Oversight Committee. During the fiscal year ended March 31, 2017, the Performance Oversight Committee met four times.

The members of the Executive Committee (the “Executive Committee”) are Rodney D. Johnson (Chair) and Collette Chilton, both of whom are Independent Trustees, and Barbara G. Novick, who serves as an interested Trustee. The principal responsibilities of the Executive Committee are to (1) act on routine matters between meetings of the Board; (2) act on such matters as may require urgent action between meetings of the Board; and (3) exercise such other authority as may from time to time be delegated to the Executive Committee by the Board. The Board has adopted a written charter for the Executive Committee. During the fiscal year ended March 31, 2017, the Executive Committee held no formal meetings. The Executive Committee met informally numerous times throughout the fiscal year.

The Governance Committee has adopted a statement of policy that describes the experience, qualifications, skills and attributes that are necessary and desirable for potential Independent Trustee candidates (the “Statement of Policy”). The Board believes that each Independent Trustee satisfied, at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. Furthermore, in determining that a particular Independent Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Independent Trustees have balanced and diverse experience, skills, attributes and qualifications, which allow the Board to operate effectively in governing the Trust and protecting the interests of shareholders. Among the attributes common to all Independent Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Fund’s investment adviser, sub-advisers, other service providers, counsel and the Independent Registered Public Accounting Firm, and to exercise effective business judgment in the performance of their duties as Trustees.

Each Trustee’s ability to perform his or her duties effectively is evidenced by his or her educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Trust and the other funds in the BlackRock Fund Complexes (and any predecessor funds), other

VI. Computation of Offering Price Per Share

The offering price for the Fund’s share classes is equal to the share class’ net asset value computed by dividing the value of the share class’ net assets by the number of shares of that share class outstanding. For more information on the purchasing and valuation of shares, please see “Purchase of Shares” and “Determination of Net Asset Value” in Part II of this SAI.

VII. Yield Information

The yield on the Fund’s shares normally will fluctuate on a daily basis. Therefore, the yield for any given past period is not an indication or representation by the Fund of future yields or rates of return on its shares. The yield is affected by such factors as changes in interest rates on the Fund’s portfolio securities, average portfolio maturity, the types and quality of portfolio securities held and operating expenses. The yield on Institutional Shares for various reasons may not be comparable to the yield on bank deposits, shares of other money market funds or other investments.

The Trust

The Trust was organized as a Massachusetts business trust on December 22, 1988, and is registered under the Investment Company Act as an open-end, management investment company. The Fund is diversified pursuant to the Investment Company Act. Effective January 31, 1998, the Trust changed its name from Compass Capital Funds ^SM to BlackRock Funds ^SM . The Trust is authorized to issue an unlimited number of shares of beneficial interest with a par value of $0.001 per share, which may be divided into different series and classes.

Under Massachusetts law, shareholders of a business trust may, under certain circumstances, be held personally liable as partners for the obligations of the Trust. However, the Trust’s Declaration of Trust provides that shareholders shall not be subject to any personal liability in connection with the assets of the Trust for the acts or obligations of the Trust, and that every note, bond, contract, order or other undertaking made by the Trust shall contain a provision to the effect that the shareholders are not personally liable thereunder. The Declaration of Trust provides for indemnification out of Trust property of any shareholder held personally liable solely by reason of his being or having been a shareholder and not because of such shareholder’s acts or omissions or some other reason. The Declaration of Trust also provides that the Trust shall, upon request, assume the defense of any claim made against any shareholder for any act or obligation of the Trust, and shall satisfy any judgment thereon.

The Declaration of Trust further provides that all persons having any claim against the Trustees or Trust shall look solely to the Trust property for payment; that no Trustee of the Trust shall be personally liable for or on account of any contract, debt, tort, claim, damage, judgment or decree arising out of or connected with the administration or preservation of the Trust property or the conduct of any business of the Trust; and that no Trustee shall be personally liable to any person for any action or failure to act except by reason of such Trustee’s own bad faith, willful misfeasance, gross negligence or reckless disregard of his duties as a Trustee. With the exception stated, the Declaration of Trust provides that a Trustee is entitled to be indemnified against all liabilities and expenses reasonably incurred by such Trustee in connection with the defense or disposition of any proceeding in which he may be involved or with which he may be threatened by reason of his being or having been a Trustee, and that the Trust will indemnify officers, representatives and employees of the Trust to the same extent that trustees are entitled to indemnification.

PART II

Part II of this Statement of Additional Information (“SAI”) contains information about the following funds: BIF Money Fund (“BIF Money”); BIF Treasury Fund (“BIF Treasury”); BBIF Money Fund (“BBIF Money”); BBIF Treasury Fund (“BBIF Treasury”); BlackRock Government Money Market Portfolio, a series of BlackRock Series Fund, Inc.; BlackRock Government Money Market V.I. Fund, a series of BlackRock Variable Series Funds, Inc.; BlackRock Money Market Portfolio (the “BlackRock Funds Portfolio”), a series of BlackRock Funds ^SM (the “Trust”); BlackRock Summit Cash Reserves Fund (“Summit Cash Reserves”) of BlackRock Financial Institutions Series Trust (“FIST”); Ready Assets Government Liquidity Fund (“Ready Assets Government Liquidity”); Ready Assets U.S.A. Government Money Fund (“U.S.A. Government Money”); Ready Assets U.S. Treasury Money Fund (“U.S. Treasury Money”); and Retirement Reserves Money Fund of Retirement Series Trust (“Retirement Reserves”).

Throughout this SAI, each of the above listed funds may be referred to as a “Fund” or collectively as the “Funds.” BIF Money and BIF Treasury may be collectively referred to herein as the “BIF Funds.” BBIF Money and BBIF Treasury may be collectively referred to herein as the “BBIF Funds.”

Each Fund is organized as a Massachusetts business trust, with the exception of BlackRock Series Fund, Inc. and BlackRock Variable Series Funds, Inc., which are Maryland corporations. For ease and clarity of presentation, common shares of beneficial interest are referred to herein as “shares” and the trustees of each Fund are referred to herein as “Trustees.” BlackRock Advisors, LLC is the manager of each Fund and is referred to as “BlackRock” or the “Manager,” and the management agreement applicable to each Fund is referred to as the “Management Agreement.” The Investment Company Act of 1940, as amended, is referred to herein as the “Investment Company Act.” The Securities Act of 1933, as amended, is referred to herein as the “Securities Act.” The Securities Exchange Act of 1934, as amended, is referred to herein as the “Exchange Act.” The Securities and Exchange Commission is referred to herein as the “Commission” or the “SEC.”

BIF Money, BIF Treasury, BBIF Money and BBIF Treasury are “feeder” funds (each, a “Feeder Fund”) that invest all of their assets in a corresponding “master” portfolio (each, a “Master Portfolio”) of a master limited liability company organized in Delaware (each, a “Master LLC”), a fund that has the same objective and strategies as the applicable Feeder Fund. All investments will be made at the level of the Master LLC. This structure is sometimes called a “master/feeder” structure. A Feeder Fund’s investment results will correspond directly to the investment results of the underlying Master LLC in which it invests. For simplicity, unless the context otherwise requires, this SAI uses the terms “Fund” or “Feeder Fund” to include both a Feeder Fund and its Master LLC.

In addition to containing information about the Funds, Part II of this SAI contains general information about all funds in the BlackRock-advised fund complex. Certain information contained herein may not be relevant to the Funds.

Investment Risks and Considerations

Set forth below are descriptions of some of the types of investments and investment strategies that one or more of the Funds may use, and the risks and considerations associated with those investments and investment strategies. Please see each Fund’s Prospectus and the “Investment Objectives and Policies” section of Part I of this SAI for further information about each Fund’s investment policies and risks. Information contained in this section about the risks and considerations associated with a Fund’s investments and/or investment strategies applies only to those Funds specifically identified in Part I of this SAI as making each type of investment or using each investment strategy (each, a “Covered Fund”). Information that does not apply to a Covered Fund does not form a part of that Covered Fund’s Statement of Additional Information and should not be relied upon by investors in that Covered Fund.

Only information that is clearly identified as applicable to a Covered Fund is considered to form a part of that Covered Fund’s Statement of Additional Information.

Bank Money Instruments. Certain Funds may invest in U.S. dollar-denominated obligations of U.S. and foreign depository institutions, including commercial and savings banks, savings and loan associations, and other institutions. Such obligations include but are not limited to certificates of deposit, bankers’ acceptances, time deposits, bank notes and deposit notes. For example, the obligations may be issued by (i) U.S. or foreign depository institutions, (ii) foreign branches or subsidiaries of U.S. depository institutions (“Eurodollar” obligations), (iii) U.S. branches or subsidiaries of foreign depository institutions (“Yankeedollar” obligations) or (iv) foreign branches or subsidiaries of foreign depository institutions. Eurodollar and Yankeedollar obligations and obligations of branches or subsidiaries of foreign depository institutions may be general obligations of the parent bank or may be limited to the issuing branch or subsidiary by the terms of the specific obligations or by government regulation. Investments in obligations of foreign depository institutions and their foreign branches and subsidiaries will only be made if determined to be of comparable quality to other investments permissible for each Fund. BIF Money, BBIF Money and

II-1

Table of Contents

Retirement Reserves may invest only in Eurodollar obligations that, by their terms, are general obligations of the U.S. parent bank. BIF Money and BBIF Money may only invest in Yankeedollar obligations issued by U.S. branches or subsidiaries of foreign banks that are subject to state or Federal banking regulations in the U.S. and that by their terms are general obligations of the foreign parent. No Fund will invest more than 25% of its total assets (taken at market value at the time of each investment) in obligations of foreign depository institutions and their foreign branches and subsidiaries or in obligations of foreign branches or subsidiaries of U.S. depository institutions that are not backed by the U.S. parent. The Funds treat bank money instruments issued by U.S. branches or subsidiaries of foreign banks as obligations issued by domestic banks (not subject to the 25% limitation) if the branch or subsidiary is subject to the same bank regulation as U.S. banks.

Eurodollar and Yankeedollar obligations, as well as other obligations of foreign depository institutions and short term obligations issued by other foreign entities, may involve additional investment risks, including adverse political and economic developments, the possible imposition of withholding taxes on interest income payable on such obligations, the possible seizure or nationalization of foreign deposits and the possible establishment of exchange controls or other foreign governmental laws or restrictions that might adversely affect the repayment of principal and the payment of interest. The issuers of such obligations may not be subject to U.S. regulatory requirements. Foreign branches or subsidiaries of U.S. banks may be subject to less stringent reserve requirements than U.S. banks. U.S. branches or subsidiaries of foreign banks are subject to the reserve requirements of the states in which they are located. There may be less publicly available information about a U.S. branch or subsidiary of a foreign bank or other issuer than about a U.S. bank or other issuer, and such entities may not be subject to the same accounting, auditing and financial record keeping standards and requirements as U.S. issuers. Evidence of ownership of Eurodollar and foreign obligations may be held outside the United States, and the Funds may be subject to the risks associated with the holding of such property overseas. Eurodollar and foreign obligations of the Funds held overseas will be held by foreign branches of each Fund’s custodian or by other U.S. or foreign banks under subcustodian arrangements complying with the requirements of the Investment Company Act.

The Manager will carefully consider the above factors in making investments in Eurodollar obligations, Yankeedollar obligations of foreign depository institutions and other foreign short term obligations, and will not knowingly purchase obligations that, at the time of purchase, are subject to exchange controls or withholding taxes. Generally, a Fund will limit its Yankeedollar investments to obligations of banks organized in Canada, France, Germany, Japan, the Netherlands, Switzerland, the United Kingdom or other industrialized nations.

Bank money instruments in which a Fund invests must be issued by depository institutions with total assets of at least $1 billion, except that a Fund may invest in certificates of deposit of smaller institutions if such certificates of deposit are Federally insured and if, as a result of such purchase, no more than 10% of total assets (taken at market value), are invested in such certificates of deposit.

Commercial Paper and Other Short Term Obligations. Commercial paper (including variable amount master demand notes and other variable rate securities, with or without forward features) refers to short term unsecured promissory notes issued by corporations, partnerships, trusts or other entities to finance short term credit needs and non-convertible debt securities ( e.g. , bonds and debentures) with no more than 397 days (13 months) remaining to maturity at the date of purchase. Short term obligations issued by trusts, corporations, partnerships or other entities include mortgage-related or asset-backed instruments, including pass-through certificates such as participations in, or bonds and notes backed by, pools of mortgage, automobile, manufactured housing or other types of consumer loans; credit card or trade receivables or pools of mortgage-backed or asset-backed securities. These structured financings will be supported by sufficient collateral and other credit enhancements, including letters of credit, insurance, reserve funds and guarantees by third parties, to enable such instruments to obtain a quality rating by a Nationally Recognized Statistical Rating Organization (“NRSRO”), if applicable. Some structured financings also use various types of swaps, among other things, to issue instruments that have interest rate, quality or maturity characteristics necessary or desirable for a Fund. These swaps may include so-called credit default swaps that might depend for payment not only on the credit of a counterparty, but also on the obligations of another entity, the “reference entity.”

Cyber Security Issues. With the increased use of technologies such as the Internet to conduct business, each Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures or breaches by a Fund’s

II-2

Table of Contents

adviser, sub-adviser(s) and other service providers (including, but not limited to, Fund accountants, custodians, transfer agents and administrators), and the issuers of securities in which the Funds invest, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with a Fund’s ability to calculate its net asset value, impediments to trading, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Funds have established business continuity plans in the event of, and risk management systems to prevent, such cyber attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Funds cannot control the cyber security plans and systems put in place by service providers to the Funds and issuers in which the Funds invest. The Funds and their shareholders could be negatively impacted as a result.

Foreign Bank Money Instruments. Foreign bank money instruments refer to U.S. dollar-denominated obligations of foreign depository institutions and their foreign branches and subsidiaries, such as, but not limited to, certificates of deposit, bankers’ acceptances, time deposits, bank notes and deposit notes. The obligations of such foreign depository institutions and their foreign branches and subsidiaries may be the general obligations of the parent bank or may be limited to the issuing branch or subsidiary by the terms of the specific obligation or by government regulation. Such investments will only be made if determined to be of comparable quality to other investments permissible for a Fund. A Fund will not invest more than 25% of its total assets (taken at market value at the time of each investment) in these obligations. Investments in foreign entities generally involve the same risks as those described above in connection with investments in Eurodollar and Yankeedollar obligations and obligations of foreign depository institutions and their foreign branches and subsidiaries. See “Bank Money Instruments.”

Foreign Short Term Debt Instruments. Foreign short term debt instruments refer to U.S. dollar-denominated commercial paper and other short term obligations issued by foreign entities. Such investments are subject to quality standards similar to those applicable to investments in comparable obligations of domestic issuers. These investments generally involve the same risks as those described above in connection with investments in Eurodollar and Yankeedollar obligations and obligations of foreign depository institutions and their foreign branches and subsidiaries. See “Bank Money Instruments.”

Forward Commitments. Certain Funds may purchase or sell money market securities on a forward commitment basis at fixed purchase terms. The purchase or sale will be recorded on the date a Fund enters into the commitment, and the value of the security will thereafter be reflected in the calculation of the Fund’s net asset value. The value of the security on the delivery date may be more or less than its purchase price. A Fund will segregate assets consisting of cash or liquid money market securities having a market value at all times at least equal to the amount of the forward purchase commitment. Although a Fund generally will enter into forward commitments with the intention of acquiring securities for its portfolio, a Fund may dispose of a commitment prior to settlement if the Manager deems it appropriate to do so.

There can be no assurance that a security purchased or sold through a forward commitment will be delivered. The value of securities in these transactions on the delivery date may be more or less than a Fund’s purchase price. The Fund may bear the risk of a decline in the value of the security in these transactions and may not benefit from appreciation in the value of the security during the commitment period.

Interfund Lending Program . Pursuant to an exemptive order granted by the SEC (the “IFL Order”), an open-end BlackRock fund (referred to as a “BlackRock fund” in this subsection), including a Fund, to the extent permitted by its investment policies and restrictions and subject to meeting the conditions of the IFL Order, has the ability to lend money to, and borrow money from, other BlackRock funds pursuant to a master interfund lending agreement (the “Interfund Lending Program”). Under the Interfund Lending Program, BlackRock funds may lend or borrow money for temporary purposes directly to or from other BlackRock funds (an “Interfund Loan”). All Interfund Loans would consist only of uninvested cash reserves that the lending BlackRock fund otherwise would invest in short-term repurchase agreements or other short-term instruments. Although the Funds may, to the extent permitted by their investment policies, participate in the Interfund Lending Program as borrowers or lenders, they typically will not need to participate as borrowers because the Funds are money market funds and are required to comply with the liquidity provisions of Rule 2a-7 under the 1940 Act.

If a BlackRock fund has outstanding bank borrowings, any Interfund Loans to such BlackRock fund would: (a) be at an interest rate equal to or lower than that of any outstanding bank loan, (b) be secured at least on an equal priority basis with at least an equivalent percentage of collateral to loan value as any outstanding bank loan that requires collateral, (c) have a maturity no longer than any outstanding bank loan (and in any event not over seven days), and (d) provide that, if an event of default occurs under any agreement evidencing an outstanding bank loan to

II-3

Table of Contents

the BlackRock fund, that event of default will automatically (without need for action or notice by the lending BlackRock fund) constitute an immediate event of default under the interfund lending agreement, entitling the lending BlackRock fund to call the Interfund Loan immediately (and exercise all rights with respect to any collateral), and cause such call to be made if the lending bank exercises its right to call its loan under its agreement with the borrowing BlackRock fund.

A BlackRock fund may borrow on an unsecured basis through the Interfund Lending Program only if its outstanding borrowings from all sources immediately after the borrowing total 10% or less of its total assets, provided that if the BlackRock fund has a secured loan outstanding from any other lender, including but not limited to another BlackRock fund, the borrowing BlackRock fund’s borrowing will be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value as any outstanding loan that requires collateral. If a borrowing BlackRock fund’s total outstanding borrowings immediately after an Interfund Loan under the Interfund Lending Program exceed 10% of its total assets, the BlackRock fund may borrow through the Interfund Lending Program on a secured basis only. A BlackRock fund may not borrow under the Interfund Lending Program or from any other source if its total outstanding borrowings immediately after the borrowing would be more than 33 1/3% of its total assets or any lower threshold provided for by the BlackRock fund’s investment restrictions.

No BlackRock fund may lend to another BlackRock fund through the Interfund Lending Program if the loan would cause the lending BlackRock fund’s aggregate outstanding loans through the Interfund Lending Program to exceed 15% of its current net assets at the time of the loan. A BlackRock fund’s Interfund Loans to any one BlackRock fund shall not exceed 5% of the lending BlackRock fund’s net assets. The duration of Interfund Loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days, and for purposes of this condition, loans effected within seven days of each other will be treated as separate loan transactions. Each Interfund Loan may be called on one business day’s notice by a lending BlackRock fund and may be repaid on any day by a borrowing BlackRock fund.

The limitations described above and the other conditions of the IFL Order permitting interfund lending are designed to minimize the risks associated with interfund lending for both the lending BlackRock fund and the borrowing BlackRock fund. However, no borrowing or lending activity is without risk. When a BlackRock fund borrows money from another BlackRock fund under the Interfund Lending Program, there is a risk that the Interfund Loan could be called on one day’s notice, in which case the borrowing BlackRock fund may have to borrow from a bank at higher rates if an Interfund Loan is not available from another BlackRock fund. Interfund Loans are subject to the risk that the borrowing BlackRock fund could be unable to repay the loan when due, and a delay in repayment to a lending BlackRock fund could result in a lost opportunity or additional lending costs. No BlackRock fund may borrow more than the amount permitted by its investment restrictions.

Investment in Other Investment Companies. Each Fund may, subject to applicable law, invest in other investment companies (including investment companies managed by BlackRock and its affiliates), including money market funds and exchange traded funds (“ETFs”), which are typically open-end funds or unit investment trusts listed on a stock exchange. In accordance with the Investment Company Act, a Fund may invest up to 10% of its total assets in securities of other investment companies (measured at the time of such investment). In addition, under the Investment Company Act a Fund may not acquire securities of an investment company if such acquisition would cause the Fund to own more than 3% of the total outstanding voting stock of such investment company and a Fund may not invest in another investment company if such investment would cause more than 5% of the value of the Fund’s total assets to be invested in securities of such investment company. (These limits do not restrict a Feeder Fund from investing all of its assets in shares of its Master Portfolio.) In addition to the restrictions on investing in other investment companies discussed above, a Fund may not invest in a registered closed-end investment company if such investment would cause the Fund and other BlackRock-advised investment companies to own more than 10% of the total outstanding voting stock of such closed-end investment company. Pursuant to the Investment Company Act (or alternatively, pursuant to exemptive orders received from the Commission) these percentage limitations do not apply to investments in affiliated money market funds, and under certain circumstances, do not apply to investments in affiliated investment companies, including ETFs. In addition, many third-party ETFs have obtained exemptive relief from the Commission to permit unaffiliated funds (such as the Funds) to invest in their shares beyond the statutory limits, subject to certain conditions and pursuant to contractual arrangements between the ETFs and the investing funds. A Fund may rely on these exemptive orders in investing in ETFs. Further, under certain circumstances a Fund may be able to rely on certain provisions of the Investment Company Act to invest in shares of unaffiliated investment companies beyond the statutory limits noted above, but subject to certain other statutory restrictions.

As with other investments, investments in other investment companies are subject to market and selection risk.

II-4

Table of Contents

Shares of investment companies, such as closed-end fund investment companies, that trade on an exchange may at times be acquired at market prices representing premiums to their net asset values. In addition, investment companies held by a Fund that trade on an exchange could trade at a discount from net asset value, and such discount could increase while the Fund holds the shares. If the market price of shares of an exchange-traded investment company decreases below the price that the Fund paid for the shares and the Fund were to sell its shares of such investment company at a time when the market price is lower than the price at which it purchased the shares, the Fund would experience a loss.

In addition, if a Fund acquires shares in investment companies, including affiliated investment companies, shareholders would bear both their proportionate share of expenses in the Fund and, indirectly, the expenses of such investment companies. Such expenses, both at the Fund level and acquired investment company level, would include management and advisory fees, unless such fees have been waived by BlackRock. Please see the relevant Fund’s Prospectus to determine whether any such management and advisory fees have been waived by BlackRock. Investments by a Fund in wholly owned investment entities created under the laws of certain countries will not be deemed an investment in other investment companies. Pursuant to guidance issued by the staff of the Commission, fees and expenses of money market funds used for the investment of cash collateral received in connection with loans of Fund securities are not treated as “acquired fund fees and expenses,” which are fees and expenses charged by other investment companies and pooled investment vehicles in which a Fund invests a portion of its assets.

To the extent shares of a Fund are held by an affiliated fund, the ability of the Fund itself to purchase other affiliated investment companies may be limited. In addition, a fund-of-funds ( e.g. , an investment company that seeks to meet its investment objective by investing significantly in other investment companies) may be limited in its ability to purchase affiliated underlying funds if such affiliated underlying funds themselves own shares of affiliated funds.

A number of publicly traded closed-end investment companies have been organized to facilitate indirect foreign investment in developing countries, and certain of such countries, such as Thailand, South Korea, Chile and Brazil, have specifically authorized such funds. There also are investment opportunities in certain of such countries in pooled vehicles that resemble open-end investment companies. The restrictions on investments in securities of investment companies set forth above may limit opportunities for a Fund to invest indirectly in certain developing countries.

Municipal Investments.

Municipal Securities. Certain Funds invest in short term municipal obligations issued by or on behalf of the states, their political subdivisions, agencies and instrumentalities and obligations of other qualifying issuers, such as issuers located in Puerto Rico, the U.S. Virgin Islands and Guam, the interest on which (and/or, in the case of property taxes, the value of which) is excludable, in the opinion of bond counsel to the issuer, from gross income for purposes of Federal income taxes and the applicable state’s income taxes (“State Taxes”). Obligations that pay interest that is excludable from gross income for Federal income tax purposes are referred to herein as “Municipal Securities,” and obligations that pay interest that is excludable from gross income for Federal income tax purposes and are exempt from the applicable State Taxes are referred to as “State Municipal Securities.” Unless otherwise indicated, references to Municipal Securities shall be deemed to include State Municipal Securities.

Municipal Securities include debt obligations issued to obtain funds for various public purposes, including construction of a wide range of public facilities, refunding of outstanding obligations and obtaining funds for general operating expenses and loans to other public institutions and facilities. In addition, certain types of bonds are issued by or on behalf of public authorities to finance various facilities operated for private profit. Such obligations are included within the term Municipal Securities if the interest paid thereon is excludable from gross income for Federal income tax purposes.

The two principal classifications of Municipal Securities are “general obligation” bonds and “revenue” or “special obligation” bonds. General obligation bonds are secured by the issuer’s pledge of its faith, credit and taxing power for the repayment of principal and the payment of interest. Revenue or special obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source such as from the user of the facility being financed. Private activity bonds (or “industrial development bonds” under pre-1986 law) are in most cases revenue bonds and do not generally constitute the pledge of the credit or taxing power of the issuer of such bonds. The repayment of the principal and the payment of interest on such private activity bonds depends solely on the ability of the user of the facilities financed by the bonds to meet its financial obligation and the pledge, if any, of real and personal property so financed as security for such payment. In addition, private activity bonds may pay interest that is subject to the

II-5

Table of Contents

Federal alternative minimum tax. A Fund’s portfolio may include “moral obligation” bonds, which are normally issued by special purpose public authorities. If an issuer of moral obligation bonds is unable to meet its debt service obligations from current revenues, it may draw on a reserve fund, the restoration of which is a moral commitment but not a legal obligation of a state or municipality.

Yields on Municipal Securities are dependent on a variety of factors, including the general condition of the money market and of the municipal bond market, the size of a particular offering, the maturity of the obligation, and the rating of the issuer. The ability of a Fund to achieve its investment objective is also dependent on the continuing ability of the issuers of the Municipal Securities in which the Fund invests to meet their obligations for the payment of interest and the repayment of principal when due. There are variations in the risks involved in holding Municipal Securities, both within a particular classification and between classifications, depending on numerous factors. Furthermore, the rights of holders of Municipal Securities and the obligations of the issuers of such Municipal Securities may be subject to applicable bankruptcy, insolvency and similar laws and court decisions affecting the rights of creditors generally, and such laws, if any, which may be enacted by Congress or state legislatures affecting specifically the rights of holders of Municipal Securities.

A Fund’s ability to distribute dividends exempt from Federal income tax will depend on the exclusion from gross income of the interest income that it receives on the Municipal Securities in which it invests. A Fund will only purchase a Municipal Security if it is accompanied by an opinion of counsel to the issuer, which is delivered on the date of issuance of that security, that interest on such securities is excludable from gross income for Federal income tax purposes (the “tax exemption opinion”).

Events occurring after the date of issuance of the Municipal Securities, however, may cause the interest on such securities to be includable in gross income for Federal income tax purposes. For example, the Internal Revenue Code of 1986, as amended (the “Code”) establishes certain requirements, such as restrictions as to the investment of the proceeds of the issue, limitations as to the use of proceeds of such issue and the property financed by such proceeds, and the payment of certain excess earnings to the Federal government, that must be met after the issuance of the Municipal Securities for interest on such securities to remain excludable from gross income for Federal income tax purposes. The issuers and the conduit borrowers of the Municipal Securities generally covenant to comply with such requirements and the tax exemption opinion generally assumes continuing compliance with such requirements. Failure to comply with these continuing requirements, however, may cause the interest on such Municipal Securities to be includable in gross income for Federal income tax purposes retroactive to their date of issue.

In addition, the Internal Revenue Service (“IRS”) has an ongoing enforcement program that involves the audit of tax exempt bonds to determine whether an issue of bonds satisfies all of the requirements that must be met for interest on such bonds to be excludable from gross income for Federal income tax purposes. From time to time, some of the Municipal Securities held by a Fund may be the subject of such an audit by the IRS, and the IRS may determine that the interest on such securities is includable in gross income for Federal income tax purposes either because the IRS has taken a legal position adverse to the conclusion reached by the counsel to the issuer in the tax exemption opinion or as a result of an action taken or not taken after the date of issue of such obligation.

If interest paid on a Municipal Security in which a Fund invests is determined to be taxable subsequent to the Fund’s acquisition of such security, the IRS may demand that such Fund pay taxes on the affected interest income and, if the Fund agrees to do so, its yield could be adversely affected. If the interest paid on any Municipal Security held by a Fund is determined to be taxable, such Fund will dispose of the security as soon as practicable. A determination that interest on a security held by a Fund is includable in gross income for Federal or state income tax purposes retroactively to its date of issue may, likewise, cause a portion of prior distributions received by shareholders to be taxable to those shareholders in the year of receipt.

From time to time, proposals have been introduced before Congress for the purpose of restricting or eliminating the Federal income tax exclusion for interest on Municipal Securities. Similar proposals may be introduced in the future. If such a proposal were enacted, the ability of each Fund to pay “exempt-interest dividends” would be affected adversely and the Fund would re-evaluate its investment objectives and policies and consider changes in structure. See “Dividends and Taxes — Taxes.”

Municipal Securities — Derivative Products. Derivative Products are typically structured by a bank, broker-dealer or other financial institution. A Derivative Product generally consists of a trust or partnership through which a Fund holds an interest in one or more underlying bonds coupled with a right to sell (“put”) the Fund’s interest in the underlying bonds at par plus accrued interest to a financial institution (a “Liquidity Provider”). Typically, a Derivative Product is structured as a trust or partnership that provides for pass-through tax-exempt income. There are currently

II-6

Table of Contents

three principal types of derivative structures: (1) “Tender Option Bonds,” which are instruments that grant the holder thereof the right to put an underlying bond at par plus accrued interest at specified intervals to a Liquidity Provider; (2) “Swap Products,” in which the trust or partnership swaps the payments due on an underlying bond with a swap counterparty who agrees to pay a floating municipal money market interest rate; and (3) “Partnerships,” which allocate to the partners portions of income, expenses, capital gains and losses associated with holding an underlying bond in accordance with a governing agreement. A Fund may also invest in other forms of short term Derivative Products eligible for investment by money market funds.

Investments in Derivative Products raise certain tax, legal, regulatory and accounting issues that may not be presented by investments in municipal bonds. There is some risk that certain issues could be resolved in a manner that could adversely impact the performance of a Fund. For example, the tax-exempt treatment of the interest paid to holders of Derivative Products is premised on the legal conclusion that the holders of such Derivative Products have an ownership interest in the underlying bonds. Were the IRS or any state taxing authority to issue an adverse ruling or take an adverse position with respect to the taxation of Derivative Products, there is a risk that the interest paid on such Derivative Products or, in the case of property taxes, the value of such Fund to the extent represented by such Derivative Products, would be deemed taxable at the Federal and/or state level.

Municipal Notes. Municipal notes are shorter term municipal debt obligations. They may provide interim financing in anticipation of tax collection, bond sales or revenue receipts. If there is a shortfall in the anticipated proceeds, the note may not be fully repaid and a Fund may lose money.

Municipal Commercial Paper. Municipal commercial paper is generally unsecured and issued to meet short term financing needs. The lack of security presents some risk of loss to a Fund since, in the event of an issuer’s bankruptcy, unsecured creditors are repaid only after the secured creditors are paid out of the assets, if any, that remain.

Municipal Lease Obligations. Also included within the general category of State Municipal Securities are Certificates of Participation (“COPs”) issued by governmental authorities or entities to finance the acquisition or construction of equipment, land and/or facilities. The COPs represent participations in a lease, an installment purchase contract or a conditional sales contract (hereinafter collectively called “lease obligations”) relating to such equipment, land or facilities. Although lease obligations do not constitute general obligations of the issuer for which the issuer’s unlimited taxing power is pledged, a lease obligation is frequently backed by the issuer’s covenant to budget for, appropriate and make the payments due under the lease obligation. However, certain lease obligations contain “non-appropriation” clauses that provide that the issuer has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although “non-appropriation” lease obligations are secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. The securities represent a type of financing that has not yet developed the depth of marketability associated with more conventional securities. Certain investments in lease obligations may be illiquid. A Fund may not invest in illiquid lease obligations if such investments, together with all other illiquid investments, would exceed 5% of such Fund’s net assets. A Fund may, however, invest without regard to such limitation in lease obligations that the Manager, pursuant to guidelines adopted by the Board of Trustees and subject to the supervision of the Board, determines to be liquid. The Manager will deem lease obligations to be liquid if they are publicly offered and have received an investment grade rating of Baa or better by Moody’s Investors Service, Inc. (“Moody’s”), or BBB or better by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”). Unrated lease obligations, or those rated below investment grade, will be considered liquid if the obligations come to the market through an underwritten public offering and at least two dealers are willing to give competitive bids. In reference to the latter, the Manager must, among other things, also review the creditworthiness of the entity obligated to make payment under the lease obligation and make certain specified determinations based on such factors as the existence of a rating or credit enhancement, such as insurance, the frequency of trades or quotes for the obligation and the willingness of dealers to make a market in the obligation.

Municipal Securities — Short-Term Maturity Standards. All of the investments of a Fund in Municipal Securities will be in securities with remaining maturities of 397 days (13 months) or less. The dollar-weighted average maturity of each Fund’s portfolio will be 60 days or less. For purposes of this investment policy, an obligation will be treated as having a maturity earlier than its stated maturity date if such obligation has technical features that, in the judgment of the Manager, will result in the obligation being valued in the market as though it has such earlier maturity.

The maturities of Variable Rate Demand Obligations (“VRDOs”) (including Participating VRDOs) are deemed to be the longer of (i) the notice period required before a Fund is entitled to receive payment of the principal amount of the VRDOs on demand or (ii) the period remaining until the VRDO’s next interest rate adjustment. If not redeemed by a

II-7

Table of Contents

Fund through the demand feature, VRDOs mature on a specified date, which may range up to 30 years from the date of issuance. See “VRDOs and Participating VRDOs” below.

Municipal Securities — Quality Standards. A Fund’s portfolio investments in municipal notes and short term tax-exempt commercial paper will be limited to those obligations that are (i) secured by a pledge of the full faith and credit of the United States or (ii) otherwise are determined by the Manager to present minimal credit risks to the Fund. A Fund’s investments in municipal bonds will be in securities that have been determined by the Manager to present minimal credit risks to the Fund. In addition, certain Funds may require that portfolio investments (or their issuers) receive minimum credit ratings from one or more NRSROs, or if not rated, are determined by the Manager to be of comparable quality to securities that have received such rating(s). Certain tax-exempt obligations (primarily VRDOs and Participating VRDOs) may be entitled to the benefit of letters of credit or similar credit enhancements issued by financial institutions. In such instances, in assessing the quality of such instruments, the Trustees and the Manager will take into account not only the creditworthiness of the issuers, but also the creditworthiness and type of obligation of the financial institution. The type of obligation of the financial institution concerns, for example, whether the letter of credit or similar credit enhancement being issued is conditional or unconditional. For a description of debt ratings, see Appendix A — “Description of Bond Ratings.”

A Fund may not invest in any security issued by a depository institution unless such institution is organized and operating in the United States, has total assets of at least $1 billion and is federally insured. Preservation of capital is a prime investment objective of the Funds, and while the types of money market securities in which the Funds invest generally are considered to have low principal risk, such securities are not completely risk free. There is a risk of the failure of issuers or credit enhancers to meet their principal and interest obligations. With respect to repurchase agreements and purchase and sale contracts, there is also the risk of the failure of the parties involved to repurchase at the agreed-upon price, in which event each Fund may suffer time delays and incur costs or possible losses in connection with such transactions.

Municipal Securities — Other Factors. Management of the Funds will endeavor to be as fully invested as reasonably practicable in order to maximize the yield on each Fund’s portfolio. Not all short term municipal securities trade on the basis of same day settlements and, accordingly, a portfolio of such securities cannot be managed on a daily basis with the same flexibility as a portfolio of money market securities, which can be bought and sold on a same day basis. There may be times when a Fund has uninvested cash resulting from an influx of cash due to large purchases of shares or the maturing of portfolio securities. A Fund also may be required to maintain cash reserves or incur temporary bank borrowings to make redemption payments, which are made on the same day the redemption request is received. Such inability to be invested fully would lower the yield on such Fund’s portfolio.

Because certain Funds may at times invest a substantial portion of their assets in Municipal Securities secured by bank letters of credit or guarantees, an investment in a Fund should be made with an understanding of the characteristics of the banking industry and the risks that such an investment in such credit enhanced securities may entail. Banks are subject to extensive governmental regulations that may limit both the amounts and types of loans and other financial commitments that may be made and interest rates and fees that may be charged. The profitability of the banking industry is largely dependent on the availability and cost of capital funds for the purpose of financing lending operations under prevailing money market conditions. Furthermore, general economic conditions play an important part in the operations of this industry and exposure to credit losses arising from possible financial difficulties of borrowers might affect a bank’s ability to meet its obligations under a letter of credit.

Changes to the Code may limit the types and volume of securities qualifying for the Federal income tax exemption of interest; this may affect the availability of Municipal Securities for investment by the Funds, which could, in turn, have a negative impact on the yield of the portfolios. A Fund reserves the right to suspend or otherwise limit sales of its shares if, as a result of difficulties in acquiring portfolio securities or otherwise, it is determined that it is not in the interests of the Fund’s shareholders to issue additional shares.

VRDOs and Participating VRDOs. VRDOs are tax-exempt obligations that contain a floating or variable interest rate adjustment formula and right of demand on the part of the holder thereof to receive payment of the unpaid balance plus accrued interest upon a short notice period not to exceed seven days. There is, however, the possibility that because of default or insolvency the demand feature of VRDOs and Participating VRDOs (described below) may not be honored. The interest rates are adjustable at intervals (ranging from daily to one year) to some prevailing market rate of the VRDOs at approximately the par value of the VRDOs on the adjustment date. The adjustment may be based upon the Public Securities Index or some other appropriate interest rate adjustment index. Each Fund may invest in all types of tax-exempt instruments currently outstanding or to be issued in the future that satisfy its short term maturity and quality standards.

II-8

Table of Contents

Participating VRDOs provide a Fund with a specified undivided interest (up to 100%) in the underlying obligation and the right to demand payment of the unpaid principal balance plus accrued interest on the Participating VRDOs from a financial institution upon a specified number of days’ notice, not to exceed seven days. In addition, a Participating VRDO is backed by an irrevocable letter of credit or guaranty of the financial institution. A Fund would have an undivided interest in an underlying obligation and thus participate on the same basis as the financial institution in such obligation except that the financial institution typically retains fees out of the interest paid on the obligation for servicing the obligation, providing the letter of credit or issuing the repurchase commitment. Certain Funds have been advised by counsel that they should be entitled to treat the income received on Participating VRDOs as interest from tax-exempt obligations. It is contemplated that no Fund will invest more than a limited amount of its total assets in Participating VRDOs.

VRDOs that contain a right of demand to receive payment of the unpaid principal balance plus accrued interest on a notice period exceeding seven days may be deemed to be illiquid securities. A VRDO with a demand notice period exceeding seven days will, therefore, be subject to each Fund’s restrictions on illiquid investments unless, in the judgment of the Trustees, such VRDO is liquid. The Trustees may adopt guidelines and delegate to the Manager the daily function of determining and monitoring liquidity of such VRDOs. The Trustees, however, will retain sufficient oversight and be ultimately responsible for such determinations.

Because of the interest rate adjustment formula on VRDOs (including Participating VRDOs), the VRDOs are not comparable to fixed rate securities. A Fund’s yield on VRDOs will decline and its shareholders will forego the opportunity for capital appreciation during periods when prevailing interest rates have declined. On the other hand, during periods where prevailing interest rates have increased, a Fund’s yield on VRDOs will increase and its shareholders will have a reduced risk of capital depreciation.

Purchase of Securities with Fixed Price “Puts.” Certain Funds have authority to purchase fixed rate Municipal Securities and, for a price, simultaneously acquire the right to sell such securities back to the seller at an agreed-upon rate at any time during a stated period or on a certain date. Such a right is generally denoted as a fixed price put. Puts with respect to fixed rate instruments are to be distinguished from the demand or repurchase features of VRDOs and Participating VRDOs that enable certain Funds to dispose of such a security at a time when the market value of the security approximates its par value.

Repurchase Agreements and Purchase and Sale Contracts. Funds may invest in Taxable Securities (as defined below, see “Taxable Money Market Securities”) pursuant to repurchase agreements. Repurchase agreements may be entered into only with a member bank of the Federal Reserve System or primary dealer in U.S. Government securities or an affiliate thereof that meets the creditworthiness standards adopted by the Manager. Under such agreements, the bank or primary dealer or an affiliate thereof agrees, upon entering into the contract, to repurchase the security at a mutually agreed upon time and price, thereby determining the yield during the term of the agreement. This results in a fixed rate of return insulated from market fluctuations during such period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. In the case of a repurchase agreement, a Fund will require the seller to provide additional collateral if the market value of the securities falls below the repurchase price at any time during the term of the repurchase agreement. One common type of repurchase agreement a Fund may enter into is a “tri-party” repurchase agreement. In “tri-party” repurchase agreements, an unaffiliated third party custodian maintains accounts to hold collateral for the Fund and its counterparties and, therefore, the Fund may be subject to the credit risk of those custodians. In any repurchase transaction to which a Fund is a party, collateral for a repurchase agreement may include cash items and obligations issued by the U.S. Government or its agencies or instrumentalities. Collateral, however, is not limited to the foregoing and may include, for example, obligations rated below the highest category by NRSROs, including collateral that may be below investment grade. Collateral for a repurchase agreement may also include securities that a Fund could not hold directly without the repurchase obligation. Irrespective of the type of collateral underlying the repurchase agreement, the Fund must determine that a repurchase obligation with a particular counterparty involves minimal credit risk to the Fund and otherwise satisfies any additional credit quality standards applicable to the Fund.

In the event of default by the seller under a repurchase agreement construed to be a collateralized loan, the underlying securities are not owned by the Fund but only constitute collateral for the seller’s obligation to pay the repurchase price. Therefore, a Fund may suffer time delays and incur costs or possible losses in connection with the disposition of the collateral. In the event of a default under a repurchase agreement that is construed to be a collateralized loan, instead of the contractual fixed rate of return, the rate of return to a Fund will depend upon intervening fluctuations of the market value of such security and the accrued interest on the security. In such event, a Fund would have rights against the seller for breach of contract with respect to any losses arising from market fluctuations following the failure of the seller to perform. In general, for Federal income tax purposes, repurchase

II-9

Table of Contents

agreements are treated as collateralized loans secured by the securities “sold.” Therefore, amounts earned under such agreements, even if the underlying securities are tax-exempt securities, will not be considered tax-exempt interest. From time to time, a Fund also may invest in money market securities pursuant to purchase and sale contracts. While purchase and sale contracts are similar to repurchase agreements, purchase and sale contracts are structured so as to be in substance more like a purchase and sale of the underlying security than is the case with repurchase agreements and, with purchase and sale contracts, the purchaser receives any interest on the security paid during the period of the contract.

Repurchase agreements pose certain risks for a Fund that utilizes them. Such risks are not unique to the Fund but are inherent in repurchase agreements. The Funds seek to minimize such risks but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, a Fund would retain the status of an unsecured creditor of the counterparty ( i.e. , the position the Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, a Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. A Fund may enter into reverse repurchase agreements with the same parties with whom it may enter into repurchase agreements. Under a reverse repurchase agreement, a Fund sells securities to another party and agrees to repurchase them at a mutually agreed-upon date and price. At the time a Fund enters into a reverse repurchase agreement, it will segregate liquid assets with a value not less than the repurchase price (including accrued interest). Reverse repurchase agreements involve the risk that (i) the market value of the securities retained in lieu of sale by a Fund may decline below the price of the securities the Fund has sold but is obligated to repurchase and (ii) the price of the securities sold may decline below the price at which the Fund is required to repurchase them. In addition, if the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, such buyer or its trustee or receiver may receive an extension of time to determine whether to enforce a Fund’s obligations to repurchase the securities and the Fund’s use of the proceeds of the reverse repurchase agreement may effectively be restricted pending such decision.

Rule 2a-7 Requirements. Rule 2a-7 under the Investment Company Act sets forth portfolio maturity, liquidity, diversification and quality requirements applicable to all money market funds.

Maturity. Each Fund is managed so that the dollar-weighted average maturity of all of its investments will be 60 days or less, and the dollar-weighted average life of all of its investments will be 120 days or less. In addition, the Funds will not acquire any instrument with a remaining maturity of greater than 397 days. The “dollar-weighted average maturity” of a Fund is the average amount of time until the issuers of the debt securities in the Fund’s portfolio must pay off the principal amount of the debt. “Dollar-weighted” means the larger the dollar value of a debt security in a Fund, the more weight it gets in calculating this average. To calculate the dollar-weighted average maturity, the Fund may treat a variable or floating rate security under certain circumstances as having a maturity equal to the time remaining to the security’s next interest rate reset date rather than the security’s actual maturity. “Dollar-weighted average life” of a Fund’s portfolio is calculated without reference to the exceptions used in calculating the dollar-weighted average maturity for variable or floating rate securities regarding the use of interest rate reset dates.

Liquidity. Rule 2a-7 contains a “general liquidity requirement” that requires that each Fund hold securities that are sufficiently liquid to meet reasonably foreseeable shareholder redemptions in light of its obligations under section 22(e) of the Investment Company Act, and any commitments the Fund has made to shareholders. To comply with this general liquidity requirement, each Fund’s adviser or sub-adviser must consider factors that could affect the Fund’s liquidity needs, including characteristics of the Fund’s investors and their likely redemptions. Depending upon the volatility of its cash flows (particularly shareholder redemptions), this provision may require a Fund to maintain greater liquidity than would be required by the daily and weekly minimum liquidity requirements discussed below. The Funds will not acquire any security other than daily liquid assets unless, immediately following such purchase, at least 10% of its total assets would be invested in daily liquid assets. The Funds will not acquire any security other than weekly liquid assets unless, immediately following such purchase, at least 30% of its total assets would be invested in weekly liquid assets. “Daily Liquid Assets” include (i) cash; (ii) direct obligations of the U.S. Government; (iii) securities that will mature, as determined without reference to the maturity shortening provisions of Rule 2a-7 regarding interest rate readjustments, or are subject to a demand feature that is exercisable and payable within one

II-10

Table of Contents

business day; and (iv) amounts receivable and due unconditionally within one business day on pending sales of portfolio securities. “Weekly Liquid Assets” include (i) cash; (ii) direct obligations of the U.S. Government; (iii) U.S. Government securities issued by a person controlled or supervised by and acting as an instrumentality of the U.S. Government pursuant to authority granted by the U.S. Congress, that are issued at a discount to the principal amount to be repaid at maturity without provision for the payment of interest and have a remaining maturity of 60 days or less; (iv) securities that will mature, as determined without reference to the maturity shortening provisions of Rule 2a-7 regarding interest rate readjustments, or are subject to a demand feature that is exercisable and payable within five business days; and (v) amounts receivable and due unconditionally within five business days on pending sales of portfolio securities. No Fund will invest more than 5% of the value of its total assets in securities that are illiquid ( i.e. , securities that cannot be sold or disposed of in the ordinary course of business within seven days at approximately the value ascribed to them by the Fund).

Portfolio Diversification and Quality. Immediately after the acquisition of any security, taxable money market funds must not have invested more than: Five percent of its total assets in securities issued by the issuer of the security, provided, however, such a fund may invest up to twenty-five percent of its total assets in the securities of a single issuer for a period of up to three business days after the acquisition thereof; provided, further, that the fund may not invest in the securities of more than one issuer in accordance with the foregoing proviso at any time; and ten percent of its total assets in securities issued by or subject to demand features or guarantees from the institution that issued the demand feature or guarantee.

Government Money Market Funds. A government money market fund invests at least 99.5% of its total assets in obligations of the U.S. government, including obligations of the U.S. Treasury and federal agencies and instrumentalities, as well as repurchase agreements collateralized by government securities. Under Rule 2a-7, a government money market fund may, but is not required to, impose liquidity fees and suspend redemptions. The Board of Directors has determined that each Fund that is a government money market fund will not be subject to liquidity fees and redemption gates under Rule 2a-7.

Securities Lending. Each Fund may lend portfolio securities to certain borrowers determined to be creditworthy by BlackRock, including to borrowers affiliated with BlackRock. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of a Fund if, as a result, the aggregate value of all securities loans of the particular Fund exceeds one-third of the value of such Fund’s total assets (including the value of the collateral received). A Fund may terminate a loan at any time and obtain the return of the securities loaned. Each Fund is paid the value of any interest or cash or non-cash distributions paid on the loaned securities that it would have otherwise received if the securities were not on loan.

With respect to loans that are collateralized by cash, the borrower may be entitled to receive a fee based on the amount of cash collateral. The Funds are compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, a Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral received by the Fund for such loans, and uninvested cash, may be invested, among other things, in a private investment company managed by an affiliate of the Manager or in registered money market funds advised by the Manager or its affiliates; such investments are subject to investment risk.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees each Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for a Fund. A Fund could lose money if its short-term investment of the collateral declines in value over the period of the loan. Substitute payments for dividends received by a Fund for securities loaned out by the Fund will not be considered qualified dividend income. The securities lending agent will take the tax effects on shareholders of this difference into account in connection with the Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income.

Structured Notes. Structured notes and other related instruments purchased by a Fund are generally privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a specific asset, benchmark asset, market or interest rate (“reference measure”). Issuers of structured notes include

II-11

Table of Contents

corporations and banks. The interest rate or the principal amount payable upon maturity or redemption may increase or decrease, depending upon changes in the value of the reference measure. The terms of a structured note may provide that, in certain circumstances, no principal is due at maturity and, therefore, may result in a loss of invested capital by a Fund. The interest and/or principal payments that may be made on a structured product may vary widely, depending on a variety of factors, including the volatility of the reference measure.

Structured notes may be positively or negatively indexed, so the appreciation of the reference measure may produce an increase or a decrease in the interest rate or the value of the principal at maturity. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of reference measures. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

The purchase of structured notes exposes a Fund to the credit risk of the issuer of the structured product. Structured notes may also be more volatile, less liquid, and more difficult to price accurately than less complex securities and instruments or more traditional debt securities. The secondary market for structured notes could be illiquid making them difficult to sell when the Fund determines to sell them. The possible lack of a liquid secondary market for structured notes and the resulting inability of the Fund to sell a structured note could expose the Fund to losses and could make structured notes more difficult for the Fund to value accurately.

Taxable Money Market Securities. Certain Funds may invest in a variety of taxable money market securities (“Taxable Securities”). The Taxable Securities in which certain Funds may invest consist of U.S. Government securities, U.S. Government agency securities, domestic bank certificates of deposit and bankers’ acceptances, short term corporate debt securities such as commercial paper and repurchase agreements. These investments must have a maturity not in excess of 397 days (13 months) from the date of purchase.

The standards applicable to Taxable Securities in which certain Funds invest are essentially the same as those described above with respect to Municipal Securities. Certain Funds may not invest in any security issued by a depository institution unless such institution is organized and operating in the United States, has total assets of at least $1 billion and is federally insured. Taxable Securities in which the Funds invest will be determined by the Manager to present minimal credit risks to the Fund, and certain Funds may require that portfolio investments (or their issuers) receive minimum credit ratings from one or more NRSROs, or if not rated, are determined by the Manager to be of comparable quality to securities that have received such rating(s).

U.S. Government Obligations. Examples of the types of U.S. Government obligations that may be held by certain Funds include U.S. Treasury Bills, Treasury Notes and Treasury Bonds and the obligations of the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, the Government National Mortgage Association (“Ginnie Mae”), the Federal National Mortgage Association (“Fannie Mae”), Federal Financing Bank, General Services Administration, The Co-operative Central Bank, Federal Home Loan Banks, the Federal Home Loan Mortgage Corporation (“Freddie Mac”), Farm Credit System and Tennessee Valley Authority. Certain Funds may also invest in mortgage-related securities issued or guaranteed by U.S. Government agencies and instrumentalities, including such obligations of Ginnie Mae, Fannie Mae and Freddie Mac.

To the extent consistent with their respective investment objectives, the Funds may invest in a variety of U.S. Treasury obligations and obligations issued by or guaranteed by the U.S. Government or its agencies, instrumentalities or U.S. Government sponsored enterprises. Not all U.S. Government obligations carry the same credit support. No assurance can be given that the U.S. Government would provide financial support to its agencies, instrumentalities or U.S. Government sponsored enterprises if it were not obligated to do so by law. There is no assurance that these commitments will be undertaken or complied with in the future.

In addition, certain Funds may invest in U.S. Treasury Floating Rate Notes (FRNs), which are two-year notes issued by the U.S. Treasury. The interest rate of an FRN changes over the life of the FRN and is the sum of an index rate and a spread. The index rate of an FRN is tied to the highest accepted discount rate of the most recent 13-week Treasury bill and is re-set every week. The spread is a rate applied to the index rate. The spread stays the same for the life of an FRN. The spread is determined at the auction where the FRN is first offered. The spread is the highest accepted discount margin in that auction. See also “Variable and Floating Rate Instruments” below.

Variable and Floating Rate Instruments. Certain Funds may purchase variable and floating rate instruments. Variable and floating rate instruments are subject to the credit quality standards described in the prospectuses. A Fund invests in variable or floating rate notes only when the Manager deems the investment to involve minimal credit risk. In some cases, the Funds may require that the obligation to pay the principal of the instrument be backed by a letter of credit or guarantee. Such instruments may carry stated maturities in excess of 13 months provided that the

II-12

Table of Contents

maturity-shortening provisions stated in Rule 2a-7 are satisfied. Although a particular variable or floating rate demand instrument may not be actively traded in a secondary market, in some cases, a Fund may be entitled to principal on demand and may be able to resell such notes in the dealer market.

Variable and floating rate instruments held by a Fund generally may have maturities of more than 13 months provided: (i) they are subject to a demand feature entitling the Fund to the payment of principal and interest within 13 months of exercise, unless the instrument is issued or guaranteed by the U.S. Government or its agencies and/or instrumentalities, and (ii) the rate of interest on such instruments is adjusted at periodic intervals which may extend up to 13 months.

In determining a Fund’s weighted average portfolio maturity and whether a long-term variable rate demand instrument has a remaining maturity of 13 months or less, the instrument will be deemed by a Fund to have a maturity equal to the longer of the period remaining until its next interest rate adjustment or the period remaining until the principal amount can be recovered through demand. In determining a Fund’s weighted average portfolio maturity and whether a long-term floating rate demand instrument has a remaining maturity of 13 months or less, the instrument will be deemed by a Fund to have a maturity equal to the period remaining until the principal amount can be recovered through demand. In addition, a variable or floating rate instrument issued or guaranteed by the U.S. Government or its agencies and/or instrumentalities will be deemed by a Fund to have a maturity equal to the period remaining until its next interest rate adjustment (in the case of a variable rate instrument) or one day (in the case of a floating rate instrument). Variable and floating rate notes are frequently rated by credit rating agencies, and their issuers must satisfy the Fund’s quality and maturity requirements. If an issuer of such a note were to default on its payment obligation, the Fund might be unable to dispose of the note because of the absence of an active secondary market and might, for this or other reasons, suffer a loss.

When Issued Securities, Delayed Delivery Securities and Forward Commitments. A Fund may purchase or sell securities that it is entitled to receive on a when issued basis. A Fund may also purchase or sell securities on a delayed delivery basis or through a forward commitment (including on a “TBA” (to be announced) basis). These transactions involve the purchase or sale of securities by a Fund at an established price with payment and delivery taking place in the future. The Fund enters into these transactions to obtain what is considered an advantageous price to the Fund at the time of entering into the transaction. When a Fund purchases securities in these transactions, the Fund segregates liquid securities in an amount equal to the amount of its purchase commitments.

Pursuant to recommendations of the Treasury Market Practices Group, which is sponsored by the Federal Reserve Bank of New York, a Fund or its counterparty generally will be required to post collateral when entering into certain forward-settling transactions, including without limitation TBA transactions.

There can be no assurance that a security purchased on a when issued basis will be issued or that a security purchased or sold on a delayed delivery basis or through a forward commitment will be delivered. Also, the value of securities in these transactions on the delivery date may be more or less than the price paid by the Fund to purchase the securities. The Fund will lose money if the value of the security in such a transaction declines below the purchase price and will not benefit if the value of the security appreciates above the sale price during the commitment period.

If deemed advisable as a matter of investment strategy, a Fund may dispose of or renegotiate a commitment after it has been entered into, and may sell securities it has committed to purchase before those securities are delivered to the Fund on the settlement date. In these cases the Fund may realize a taxable capital gain or loss.

When a Fund engages in when-issued, TBA or forward commitment transactions, it relies on the other party to consummate the trade. Failure of such party to do so may result in the Fund’s incurring a loss or missing an opportunity to obtain a price considered to be advantageous.

The market value of the securities underlying a commitment to purchase securities, and any subsequent fluctuations in their market value, is taken into account when determining the market value of a Fund starting on the day the Fund agrees to purchase the securities. The Fund does not earn interest on the securities it has committed to purchase until they are paid for and delivered on the settlement date.

Diversification Status

Each Fund’s investments will be limited in order to allow the Fund to continue to qualify as a regulated investment company (“RIC”) under the Code. To qualify, among other requirements, each Fund will limit its investments so that at the close of each quarter of the taxable year (i) at least 50% of the market value of each Fund’s total assets is represented by cash, securities of other RICs, U.S. government securities and other securities, with such other securities limited, in respect of any one issuer, to an amount not greater than 5% of the Fund’s

II-13

Table of Contents

assets and not greater than 10% of the outstanding voting securities of such issuer and (ii) not more than 25% of the value of its assets is invested in the securities (other than U.S. government securities or securities of other RICs) of any one issuer, any two or more issuers that the Fund controls and that are determined to be engaged in the same or similar trades or businesses or related trades or businesses or in the securities of one or more qualified publicly traded partnerships ( i.e. , partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive 90% of their income from interest, dividends, capital gains, and other traditional permitted mutual fund income). See “Dividends and Taxes — Taxes.”

Each Fund has elected to be classified as “diversified” under the Investment Company Act. Each Fund must also satisfy the diversification requirements set forth in Rule 2a-7.

Management and Other Service Arrangements

Trustees and Officers

See Part I, Section III “Information on Trustees and Officers — Biographical Information,” “— Share Ownership” and “— Compensation of Trustees” of each Fund’s SAI for biographical and certain other information relating to the Trustees and officers of your Fund, including Trustees’ compensation.

Management Arrangements

Management Services. The Manager provides each Fund with investment advisory and management services. Subject to the supervision of the Board of Trustees, the Manager is responsible for the actual management of a Fund’s portfolio and reviews the Fund’s holdings in light of its own research analysis and that from other relevant sources. The responsibility for making decisions to buy, sell or hold a particular security rests with the Manager. The Manager performs certain of the other administrative services and provides all the office space, facilities, equipment and necessary personnel for management of each Fund.

Each Feeder Fund invests all or a portion of its assets in shares of a Master Portfolio. To the extent a Feeder Fund invests all of its assets in a Master Portfolio, it does not invest directly in portfolio securities and does not require management services. For such Feeder Funds, portfolio management occurs at the Master Portfolio level.

Management Fee. Each Fund has entered into a management agreement with the Manager pursuant to which the Manager receives for its services to the Fund monthly compensation at an annual rate based on the average daily net assets of the Fund. For information regarding specific fee rates for your Fund and the fees paid by your Fund to the Manager for the Fund’s last three fiscal years or other applicable periods, see Part I, Section IV “Management, Advisory and Other Service Arrangements” of each Fund’s SAI. Each Management Agreement obligates the Manager to provide investment advisory services and to pay, or cause an affiliate to pay, for maintaining its staff and personnel and to provide office space, facilities and necessary personnel for the Fund. Each Manager is also obligated to pay, or cause an affiliate to pay, the fees of all officers and Trustees of the Fund who are affiliated persons of the Manager or any affiliate.

For Funds that do not have an administration agreement with the Manager, each Management Agreement obligates the Manager to provide management services and to pay all compensation of and furnish office space for officers and employees of a Fund connected with investment and economic research, trading and investment management of the Fund, as well as the fees of all Trustees of the Fund who are interested persons of the Fund. Each Fund pays all other expenses incurred in the operation of that Fund, including among other things: taxes; expenses for legal and auditing services; costs of preparing, printing and mailing proxies, shareholder reports, prospectuses and statements of additional information, except to the extent paid by BlackRock Investments, LLC (the “Distributor” or “BRIL”), charges of the custodian and sub-custodian, and the transfer agent; expenses of redemption of shares; Commission fees; expenses of registering the shares under Federal, state or foreign laws; fees and expenses of Trustees who are not interested persons of a Fund as defined in the Investment Company Act; accounting and pricing costs (including the daily calculations of net asset value); insurance; interest; brokerage costs; litigation and other extraordinary or non-recurring expenses; and other expenses properly payable by the Fund. Certain accounting services are provided to each Fund by State Street Bank and Trust Company (“State Street”), BNY Mellon Investment Servicing (US) Inc. (“BNY Mellon”) or JPMorgan Chase Bank, N.A. (“JPM”) pursuant to an agreement between State Street, BNY Mellon or JPM and each Fund. Each Fund pays a fee for these services. In addition, the Manager provides certain accounting services to each Fund and the Fund pays the Manager a fee for such services. The Distributor pays certain promotional expenses of the Funds incurred in connection with the offering of shares of the Funds. Certain expenses are financed by each Fund pursuant to distribution plans in compliance with Rule 12b-1 under the Investment Company Act. See “Purchase of Shares — Distribution Plans.”

Organization of the Manager. The Manager, BlackRock Advisors, LLC, is a Delaware limited liability company and an indirect, wholly owned subsidiary of BlackRock, Inc.

Duration and Termination. Unless earlier terminated as described below, each Management Agreement will remain in effect from year to year if approved annually (a) by the Trustees or by a vote of a majority of the outstanding voting securities of the Fund and (b) by a majority of the Trustees who are not parties to such agreement or interested persons (as defined in the Investment Company Act) of any such party. The Management Agreements are not assignable and may be terminated without penalty on 60 days’ written notice at the option of either party thereto or by the vote of the shareholders of the Fund.

Other Service Arrangements

Administrative Services and Administrative Fee. Certain Funds have entered into an administration agreement (the “Administration Agreement”) with an administrator identified in the Fund’s Prospectus and Part I of the Fund’s SAI (each, an “Administrator”). For its services to a Fund, the Administrator receives monthly compensation at the annual rate set forth in each applicable Fund’s Prospectus. For information regarding any administrative fees paid by your Fund to the Administrator for the periods indicated, see Part I, Section IV “Management, Advisory and Other Service Arrangements” of that Fund’s SAI.

For Funds that have an Administrator, the Administration Agreement obligates the Administrator to provide certain administrative services to the Fund and to pay, or cause its affiliates to pay, for maintaining its staff and personnel and to provide office space, facilities and necessary personnel for the Fund. Each Administrator is also obligated to pay, or cause its affiliates to pay, the fees of those officers and Trustees of the Fund who are affiliated persons of the Administrator or any of its affiliates.

Duration and Termination of Administration Agreement. Unless earlier terminated as described below, each Administration Agreement will continue from year to year if approved annually (a) by the Board of Trustees of each applicable Fund or by a vote of a majority of the outstanding voting securities of such Fund and (b) by a majority of the Trustees of the Fund who are not parties to such contract or interested persons (as defined in the Investment Company Act) of any such party. Such contract is not assignable and may be terminated without penalty on written notice at the option of either party thereto or by the vote of the shareholders of the Fund.

Transfer Agency Services. Each Fund has entered into an agreement with a transfer agent identified in the Fund’s Prospectus and Part I of the Fund’s SAI, pursuant to which the transfer agent is responsible for the issuance, transfer, and redemption of shares and the opening and maintenance of shareholder accounts. Each Fund pays a fee for these services.

See Part I, Section IV “Management, Advisory and Other Service Arrangements — Transfer Agency Services” of each Fund’s SAI.

Independent Registered Public Accounting Firm. The Audit Committee of each Fund, the members of which are non-interested Trustees of the Fund, has selected an independent registered public accounting firm for that Fund that audits the Fund’s financial statements. Please see the inside back cover page of your Fund’s Prospectus and Part I, Section IX “Additional Information” of each Fund’s SAI for information on your Fund’s independent registered public accounting firm.

Custodian Services. The name and address of the custodian (the “Custodian”) of each Fund appears on the inside back cover page of the Fund’s Prospectus. The Custodian is responsible for safeguarding and controlling the Fund’s cash and securities, handling the receipt and delivery of securities and collecting interest and dividends on the Fund’s investments. The Custodian is authorized to establish separate accounts in foreign currencies and to cause foreign securities owned by the Fund to be held in its offices outside the United States and with certain foreign banks and securities depositories.

Accounting Services. Each Fund has entered into an agreement with State Street, BNY Mellon or JPM, pursuant to which State Street, BNY Mellon or JPM provides certain accounting and administrative services to the Fund. Each Fund pays a fee for these services. JPM provides similar accounting services to the Master LLCs. The Manager or the Administrator also provides certain accounting services to each Fund and each Fund reimburses the Manager or the Administrator for these services.

See Part I, Section IV “Management, Advisory and Other Service Arrangements — Accounting Services” of each Fund’s SAI for information on the amounts paid by your Fund and, if applicable, Master LLC, to State Street, BNY Mellon or JPM, the Manager and/or the Administrator for the periods indicated.

II-15

Distribution Expenses. Each Fund has entered into a distribution agreement with the Distributor in connection with the continuous offering of each class of shares of the Fund (the “Distribution Agreement”). The Distribution Agreement obligates the Distributor to pay certain expenses in connection with the offering of each class of shares of the Funds. After the prospectuses, statements of additional information and periodic reports have been prepared, set in type and mailed to shareholders, the Distributor pays for the printing and distribution of these documents used in connection with the offering to dealers and investors. The Distributor also pays for other supplementary sales literature and advertising costs. The Distribution Agreement is subject to the same renewal requirements and termination provisions as the Management Agreement described above. See Part I, Section V “Distribution Related Expenses” of each Fund’s SAI for information on the fees paid by your Fund for the periods indicated.

Disclosure of Portfolio Holdings

The Boards of Trustees of each Fund and the Board of Directors of the Manager have each approved Portfolio Information Distribution Guidelines (the “Guidelines”) regarding the disclosure of the Fund’s portfolio securities, as applicable, and other portfolio information. The purpose of the Guidelines is to ensure that (i) shareholders and prospective shareholders of the Funds have equal access to portfolio holdings and characteristics and (ii) third parties (such as consultants, intermediaries and third-party data providers) have access to such information no more frequently than shareholders and prospective shareholders.

Pursuant to the Guidelines, each Fund and the Manager may, under certain circumstances as set forth below, make selective disclosure with respect to a Fund’s portfolio characteristics and portfolio holdings. Each Board of Trustees has approved the adoption by the Fund of the Guidelines, and employees of the Manager are responsible for adherence to the Guidelines. The Board of Trustees provides ongoing oversight of the Fund’s and Manager’s compliance with the Guidelines.

Disclosure of material non-public information (“Confidential Information”) about a Fund’s portfolio is prohibited, except as provided in the Guidelines. Information that is non-material or that may be obtained from public sources (i.e., information that has been publicly disclosed via a filing with the Commission (e.g., fund annual report), through a press release or placement on a publicly-available internet website, or information derived or calculated from such public sources) shall not be deemed Confidential Information.

Confidential Information relating to a Fund may not be distributed to persons not employed by BlackRock unless the Fund has a legitimate business purpose for doing so.

Portfolio Characteristics and Holdings Disclosure Schedule. Portfolio characteristics and portfolio holdings may be disclosed in accordance with the below schedule.

Portfolio Characteristics: Portfolio characteristics include, but are not limited to, sector allocation, credit quality breakdown, maturity distribution, duration and convexity measures, average credit quality, average maturity, average coupon, top 10 holdings with percent of the fund held, average market capitalization, capitalization range, ROE, P/E, P/B, P/CF, P/S, and EPS. Additional characteristics specific to money market funds include, but are not limited to, historical daily and weekly liquid assets (as defined under Rule 2a-7) and historical fund net inflows and outflows.

•

Portfolio Holdings: Portfolio holdings include, but are not limited to, issuer name, CUSIP, ticker symbol, total shares and market value for equity portfolios and issuer name, CUSIP, ticker symbol, coupon, maturity current face value and market value for fixed income portfolios.

For derivatives, indicative data may also be provided, including but not limited to, pay leg, receive leg, notional amount, reset frequency, and trade counterparty. Risk related information (e.g. value at risk, standard deviation) will be treated as portfolio holdings.

Potential Conflicts of Interest

The PNC Financial Services Group, Inc. (“PNC”) has a significant economic interest in BlackRock, Inc., the parent of BlackRock Advisors, LLC, the Funds’ investment adviser. BlackRock, Inc. and PNC are considered to be affiliated persons of one another under the Investment Company Act. Certain activities of BlackRock Advisors, LLC, BlackRock, Inc. and their affiliates (collectively referred to in this section as “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), with respect to the Funds and/or other accounts managed by BlackRock or PNC, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world’s largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. BlackRock, PNC and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of a Fund, are engaged worldwide in businesses, including managing equities, fixed income securities, cash and alternative investments, and banking and other financial services, and have interests other than that of managing the Funds. These are considerations of which investors in a Fund should be aware, and which may cause conflicts of interest that could disadvantage a Fund and its shareholders. These businesses and interests include potential multiple advisory, transactional, financial and other relationships with, or interests in companies and interests in securities or other instruments that may be purchased or sold by a Fund.

BlackRock and its Affiliates have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. One or more Affiliates are also major participants in the global currency, equities, swap and fixed income markets, in each case, for the accounts of clients and, in some cases, on a proprietary basis. As such, one or more Affiliates are or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on a Fund’s performance. Such transactions, particularly in respect of most proprietary accounts or client accounts, will be executed independently of a Fund’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund.

When BlackRock and its Affiliates seek to purchase or sell the same assets for their managed accounts, including a Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for a Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or its Affiliates may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of a Fund, particularly, but not limited to, with respect to small capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding a Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or its Affiliates implement a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for a Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or its Affiliates may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause a Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding a Fund may benefit other accounts managed by BlackRock or its Affiliates. For example, the sale of a long position or establishment of a short position by a Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or their other accounts or funds, and the purchase of a security or covering of a short position in a security by a Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or their other accounts or funds.

In certain circumstances, BlackRock, on behalf of the Funds, may seek to buy from or sell securities to another fund or account advised by BlackRock or an Affiliate. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients or clients of Affiliates (“cross trades”), including the Funds, if BlackRock believes

II-20

Table of Contents

such transactions are appropriate based on each party’s investment objectives and guidelines, subject to applicable law and regulation. There may be potential conflicts of interest or regulatory issues relating to these transactions which could limit BlackRock’s decision to engage in these transactions for the Funds. BlackRock may have a potentially conflicting division of loyalties and responsibilities to the parties in such transactions.

BlackRock and its Affiliates and their clients may pursue or enforce rights with respect to an issuer in which a Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund’s investments may be negatively impacted by the activities of BlackRock or its Affiliates or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of a Fund’s investment activities may differ significantly from the results achieved by BlackRock and its Affiliates for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by a Fund. Moreover, it is possible that a Fund will sustain losses during periods in which one or more Affiliates or Affiliate-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible.

From time to time, a Fund may be restricted from purchasing or selling securities, or from engaging in other investment activities because of regulatory, legal or contractual requirements applicable to BlackRock or one or more Affiliates or other accounts managed or advised by BlackRock or its Affiliates for clients worldwide, and/or the internal policies of BlackRock and its Affiliates designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock and/or one or more Affiliates will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates are performing services or when position limits have been reached. For example, the investment activities of one or more Affiliates for their proprietary accounts and accounts under their management may limit the investment opportunities for a Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

In connection with its management of a Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates. BlackRock will not be under any obligation, however, to effect transactions on behalf of a Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of its Affiliates will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of a Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and its Affiliates, or the activities or strategies used for accounts managed by them or other client accounts could conflict with the transactions and strategies employed by BlackRock in managing a Fund.

The Funds may be included in investment models developed by BlackRock for use by clients and financial advisors. To the extent clients invest in these investment models and increase the assets under management of the Funds, the investment management fee amounts paid by the Funds to BlackRock may also increase. The liquidity of a Fund may be impacted by redemptions of the Fund by model-driven investment portfolios.

In addition, certain principals and certain employees of BlackRock are also principals or employees of Affiliates. As a result, these principals and employees may have obligations to such other entities or their clients and such obligations to other entities or clients may be a consideration of which investors in a Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of a Fund in which clients of BlackRock or its Affiliates, or, to the extent permitted by the Commission and applicable law, BlackRock or another Affiliate, serves as the counterparty, principal or issuer. In such cases, such party’s interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by a Fund may enhance the profitability of BlackRock or its Affiliates. One or more Affiliates may also create, write or issue derivatives for their clients, the underlying securities, currencies or instruments of which may be those in which a Fund invests or which may be based on the performance of the Fund. A Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates and may also enter into transactions with other clients of an Affiliate where such other clients have interests adverse to those of the Fund.

II-21

Table of Contents

At times, these activities may cause departments of BlackRock or its Affiliates to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, a Fund will deal with Affiliates on an arms-length basis.

To the extent authorized by applicable law, one or more Affiliates may act as broker, dealer, agent, lender or adviser or in other commercial capacities for a Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate will be in its view commercially reasonable, although each Affiliate, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate and such sales personnel, which may have an adverse effect on the Funds.

Subject to applicable law, the Affiliates (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Funds as broker, dealer, agent, lender, adviser or in other commercial capacities. No accounting to the Funds or their shareholders will be required, and no fees or other compensation payable by the Funds or their shareholders will be reduced by reason of receipt by an Affiliate of any such fees or other amounts.

When an Affiliate acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Funds, the Affiliate may take commercial steps in its own interests, which may have an adverse effect on the Funds. A Fund will be required to establish business relationships with its counterparties based on the Fund’s own credit standing. Neither BlackRock nor any of the Affiliates will have any obligation to allow their credit to be used in connection with a Fund’s establishment of its business relationships, nor is it expected that the Fund’s counterparties will rely on the credit of BlackRock or any of the Affiliates in evaluating the Fund’s creditworthiness.

Lending on behalf of the Funds is done by BlackRock Investment Management, LLC (“BIM”), an Affiliate of BlackRock, pursuant to SEC exemptive relief, enabling BIM to act as securities lending agent to, and receive a share of securities lending revenues from, the Funds. An Affiliate will receive compensation for managing the reinvestment of the cash collateral from securities lending. There are potential conflicts of interests in managing a securities lending program, including but not limited to: (i) BlackRock as lending agent may have an incentive to increase or decrease the amount of securities on loan or to lend particular securities in order to generate additional risk-adjusted revenue for BlackRock and its affiliates; and (ii) BlackRock as lending agent may have an incentive to allocate loans to clients that would provide more revenue to Blackrock. As described further below, BlackRock seeks to mitigate this conflict by providing its securities lending clients with equal lending opportunities over time in order to approximate pro-rata allocation.

As part of its securities lending program, BlackRock indemnifies certain clients and/or funds against a shortfall in collateral in the event of borrower default. BlackRock’s Risk and Quantitative Analytics Group (“RQA”) calculates, on a regular basis, BlackRock’s potential dollar exposure to the risk of collateral shortfall upon counterparty default (“shortfall risk”) under the securities lending program for both indemnified and non-indemnified clients. On a periodic basis, RQA also determines the maximum amount of potential indemnified shortfall risk arising from securities lending activities (“indemnification exposure limit”) and the maximum amount of counterparty-specific credit exposure (“credit limits”) BlackRock is willing to assume as well as the program’s operational complexity. RQA oversees the risk model that calculates projected shortfall values using loan-level factors such as loan and collateral type and market value as well as specific borrower counterparty credit characteristics. When necessary, RQA may further adjust other securities lending program attributes by restricting eligible collateral or reducing counterparty credit limits. As a result, the management of the indemnification exposure limit may affect the amount of securities lending activity BlackRock may conduct at any given point in time and impact indemnified and non-indemnified clients by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

BlackRock uses a predetermined systematic process in order to approximate pro-rata allocation over time. In order to allocate a loan to a portfolio: (i) BlackRock as a whole must have sufficient lending capacity pursuant to the various program limits (i.e. indemnification exposure limit and counterparty credit limits); (ii) the lending portfolio must hold the asset at the time a loan opportunity arrives; and (iii) the lending portfolio must also have enough inventory, either on its own or when aggregated with other portfolios into one single market delivery, to satisfy the loan request. In doing so, BlackRock seeks to provide equal lending opportunities for all portfolios, independent of whether BlackRock indemnifies the portfolio. Equal opportunities for lending portfolios does not guarantee equal outcomes. Specifically, short and long-term outcomes for individual clients may vary due to asset mix, asset/liability spreads on different securities, and the overall limits imposed by the firm.

II-22

Table of Contents

Purchases and sales of securities for a Fund may be bunched or aggregated with orders for other BlackRock client accounts. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if they determine that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Funds will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates, to the extent permitted by applicable law) that furnish BlackRock, the Funds, other BlackRock client accounts or other Affiliates or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock’s view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and over-the-counter (“OTC”) transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products.

Research or other services obtained in this manner may be used in servicing any or all of the Funds and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Funds based on the amount of brokerage commissions paid by the Funds and such other BlackRock client accounts. For example, research or other services that are paid for through one client’s commissions may not be used in managing that client’s account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Funds and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) (including, without limitation, ECNs in which BlackRock or its Affiliates has an investment or other interest, to the extent permitted by applicable law) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Funds. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with BlackRock’s fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or its Affiliates, provided that

II-23

Table of Contents

BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see “Proxy Voting Policies and Procedures.”

It is also possible that, from time to time, BlackRock or its Affiliates may, subject to compliance with applicable law, purchase and hold shares of a Fund. Increasing a Fund’s assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund’s expense ratio. BlackRock and its Affiliates reserve the right, subject to compliance with applicable law, to redeem at any time some or all of the shares of a Fund acquired for their own accounts. A large redemption of shares of a Fund by BlackRock or its Affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s investment flexibility, portfolio diversification and expense ratio. BlackRock seeks to consider the effect of redemptions on a Fund and other shareholders in deciding whether to redeem its shares.

It is possible that a Fund may invest in securities of, or engage in transactions with, companies with which an Affiliate has developed or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or its Affiliates has significant debt or equity investments or other interests or in which an Affiliate makes a market. A Fund also may invest in securities of, or engage in transactions with, companies to which an Affiliate provides or may in the future provide research coverage. Such investments or transactions could cause conflicts between the interests of a Fund and the interests of BlackRock, other clients of BlackRock or its Affiliates. In making investment decisions for a Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock in the course of these activities. In addition, from time to time, the activities of an Affiliate may limit a Fund’s flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for a Fund. As indicated below, BlackRock or its Affiliates may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock or of an Affiliate have an investment.

BlackRock and Chubb Limited (“Chubb”), a public company whose securities are held by BlackRock-advised funds and other accounts, partially funded the creation of a re-insurance company (“Re Co”) pursuant to which each has approximately a 9.9% ownership interest and each has representation on the board of directors. Certain employees and executives of BlackRock have a less than ½ of 1% ownership interest in Re Co. BlackRock manages the investment portfolio of Re Co, which is held in a wholly-owned subsidiary. Re Co participates as a reinsurer with reinsurance contracts underwritten by subsidiaries of Chubb. An independent director of certain BlackRock-advised funds also serves as an independent director of Chubb and has no interest or involvement in the Re Co transaction.

BlackRock and its Affiliates, their personnel and other financial service providers may have interests in promoting sales of the Funds. With respect to BlackRock and its Affiliates and their personnel, the remuneration and profitability relating to services to and sales of the Funds or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its Affiliates and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Funds or their shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or its Affiliates and such personnel resulting from transactions on behalf of or management of the Funds may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and its Affiliates and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or its Affiliates and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

BlackRock and its Affiliates may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients’ accounts may differ from the valuations for the same securities or investments assigned by a Fund’s pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund’s pricing vendors. While BlackRock will generally communicate its valuation information or determinations to a Fund’s pricing vendors and/or fund accountants, there may be instances where the Fund’s pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

II-24

Table of Contents

To the extent permitted by applicable law, a Fund may invest all or some of its short term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, a Fund, to the extent permitted by the Investment Company Act, may pay its share of expenses of a money market fund or other similarly-managed private fund in which it invests, which may result in a Fund bearing some additional expenses.

BlackRock and its Affiliates and their directors, officers and employees, may buy and sell securities or other investments for their own accounts and may have conflicts of interest with respect to investments made on behalf of a Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates of BlackRock that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that a Fund will be adversely affected by this personal trading, the Fund, BRIL and BlackRock each have adopted a Code of Ethics in compliance with Section 17(j) of the Investment Company Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund’s portfolio transactions. Each Code of Ethics is also available on the EDGAR Database on the Commission’s Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the Commission’s Public Reference Section, Washington, DC 20549-0102. Information about accessing documents on the Commission’s website may be obtained by calling the Commission at (800) SEC-0330.

BlackRock and its Affiliates will not purchase securities or other property from, or sell securities or other property to, a Fund, except that the Fund may in accordance with rules or guidance adopted under the Investment Company Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Funds and/or BlackRock by the Commission. These transactions would be effected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of a Fund may be restricted because of regulatory requirements applicable to BlackRock or its Affiliates and/or BlackRock’s internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate is performing investment banking, market making, advisory or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Funds may be prohibited from or limited in purchasing or selling securities of that company. In addition, when BlackRock is engaged to provide advisory or risk management services for a company, BlackRock may be prohibited from or limited in purchasing or selling securities of that company on behalf of a Fund, particularly where such services result in BlackRock obtaining material non-public information about the company (e.g., in connection with participation in a creditors’ committee). Similar situations could arise if personnel of BlackRock or its Affiliates serve as directors of companies the securities of which the Funds wish to purchase or sell. However, if permitted by applicable law, and where consistent with BlackRock’s policies and procedures (including the necessary implementation of appropriate information barriers), the Funds may purchase securities or instruments that are issued by such companies, are the subject of an underwriting, distribution, or advisory assignment by an Affiliate or are the subject of an advisory or risk management assignment by BlackRock, or where personnel of BlackRock or its Affiliates are directors or officers of the issuer.

The investment activities of one or more Affiliates for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Funds. For example, in certain circumstances where the Funds invest in securities issued by companies that operate in certain regulated industries, in certain emerging or international markets, or are subject to corporate or regulatory ownership definitions, or invest in certain futures and derivative transactions, there may be limits on the aggregate amount invested by Affiliates (including BlackRock) for their proprietary accounts and for client accounts (including the Funds) that may not be exceeded without the grant of a license or other regulatory or corporate consent, or, if exceeded, may cause BlackRock, the Funds or other client accounts to suffer disadvantages or business restrictions . If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of BlackRock on behalf of clients (including the Funds) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock on behalf of its clients (including the Funds) may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when BlackRock, in its sole discretion, deems it appropriate in light of potential regulatory or other restrictions on ownership or other consequences resulting from reaching investment thresholds.

II-25

Table of Contents

In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients (including the Funds), taking into consideration benchmark weight and investment strategy. When ownership in certain securities nears an applicable threshold, BlackRock may limit purchases in such securities to the issuer’s weighting in the applicable benchmark used by BlackRock to manage the Fund. If client (including Fund) holdings of an issuer exceed an applicable threshold and BlackRock is unable to obtain relief to enable the continued holding of such investments, it may be necessary to sell down these positions to meet the applicable limitations. In these cases, benchmark overweight positions will be sold prior to benchmark positions being reduced to meet applicable limitations.

In addition to the foregoing, other ownership thresholds may trigger reporting requirements to governmental and regulatory authorities, and such reports may entail the disclosure of the identity of a client or BlackRock’s intended strategy with respect to such security or asset.

To the extent permitted by applicable laws, BlackRock and its Affiliates may maintain securities indices as part of their product offerings. Index based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including BlackRock and its Affiliates may be paid licensing fees for use of their index or index name. BlackRock and its Affiliates will not be obligated to license their indices to BlackRock, and BlackRock cannot be assured that the terms of any index licensing agreement with BlackRock and its Affiliates will be as favorable as those terms offered to other index licensees.

BlackRock and its Affiliates may not serve as Authorized Participants in the creation and redemption of iShares exchange-traded funds, but may serve as Authorized Participants of third-party ETFs.

BlackRock may enter into contractual arrangements with third-party service providers to the Fund (e.g., custodians and administrators) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock’s overall relationship with such service providers. To the extent that BlackRock is responsible for paying these service providers out of its management fee, the benefits of any such fee discounts or concessions may accrue, in whole or in part, to BlackRock.

BlackRock or its Affiliates own or have an ownership interest in certain trading, portfolio management, operations and/or information systems used by Fund service providers. These systems are, or will be, used by a Fund service provider in connection with the provision of services to accounts managed by BlackRock and funds managed and sponsored by BlackRock, including the Funds, that engage the service provider (typically the custodian). A Fund’s service provider remunerates BlackRock or its Affiliates for the use of the systems. A Fund service provider’s payments to BlackRock or its Affiliates for the use of these systems may enhance the profitability of BlackRock and its Affiliates.

BlackRock’s or its Affiliates’ receipt of fees from a service provider in connection with the use of systems provided by BlackRock or its Affiliates may create an incentive for BlackRock to recommend that a Fund enter into or renew an arrangement with the service provider.

Present and future activities of BlackRock and its Affiliates, including BlackRock Advisors, LLC, in addition to those described in this section, may give rise to additional conflicts of interest.

Purchase of Shares

Each Fund offers its shares without a sales charge at a price equal to the net asset value next determined after a purchase order becomes effective. Each Fund attempts to maintain a net asset value per share of $1.00. Share purchase orders are effective on the date Federal Funds become available to a Fund. If Federal Funds are available to a Fund prior to the determination of net asset value on any business day, the order will be effective on that day. Except as otherwise specified in a Fund’s Prospectus, shares purchased will begin accruing dividends on the day following the date of purchase. Federal Funds are a commercial bank’s deposits in a Federal Reserve Bank and can be transferred from one member bank’s account to that of another member bank on the same day and thus are considered to be immediately available funds. Any order may be rejected by a Fund or the Distributor.

Shareholder Services

Each Fund offers a number of shareholder services described below that are designed to facilitate investment in shares of the Fund. Full details as to each of such services and copies of the various plans and instructions as to how to participate in the various services or plans, or how to change options with respect thereto, can be obtained from each Fund, by calling the telephone number on the cover page to Part I of your Fund’s SAI, or from the

II-26

Distributor. The types of shareholder service programs offered to shareholders include: Investment Account; Fee-Based Programs; Automatic Investment Plan; Accrued Monthly Payout Plan; Systematic Withdrawal Plan; and Retirement and Education Savings Plans.

Purchase of Shares by all Investors other than Cash Management Account ^® (“CMA”) service (or other Merrill Lynch central asset account program) Subscribers, Working Capital Management Account ^® (“WCMA”) service (or other Merrill Lynch business account program) Subscribers and Shareholders of Retirement Reserves

The minimum initial purchase is $5,000 and the minimum subsequent purchase is $1,000, except that lower minimums apply in the case of purchases made under certain retirement plans. Each Fund may, at its discretion, establish reduced minimum initial and subsequent purchase requirements with respect to various types of accounts.

If you are not a CMA service or other Merrill Lynch central asset account program subscriber, you may purchase shares of a BIF Fund directly through the Fund’s transfer agent in the manner described below under “Methods of Payment — Payment to the Transfer Agent.” Shareholders of the BIF Funds who do not subscribe to the CMA service or other Merrill Lynch central asset account program will not receive any of the services available to program subscribers such as the card/check account or automatic investment of free cash balances.

Methods of Payment

Payment Through Securities Dealers. You may purchase shares of a Fund through securities dealers, including Merrill Lynch, who have entered into selected dealer agreements with the Distributor. In such a case, the dealer will transmit payment to the Fund on your behalf and will supply the Fund with the required account information. Generally, purchase orders placed through Merrill Lynch will be made effective on the day the order is placed. Merrill Lynch has an order procedure pursuant to which you can have the proceeds from the sale of listed securities invested in shares of a Fund on the day you receive the proceeds in your Merrill Lynch securities accounts. If you have a free cash balance ( i.e. , immediately available funds) in securities accounts of Merrill Lynch, your funds will not be invested in a Fund until the day after the order is placed with Merrill Lynch. Shareholders of the BIF Funds not subscribing to the CMA service (or other Merrill Lynch central asset account program) can purchase shares through the Fund’s transfer agent.

Payment by Wire. If you maintain an account directly with the Fund’s transfer agent, you may invest in a Fund through wire transmittal of Federal Funds to the Fund’s transfer agent. A Fund will not be responsible for delays in the wiring system. Payment should be wired to Bank of America, 1401 Elm Street, Dallas, Texas 75202. You should give your financial institution the following wiring instructions: ABA #026009593 Merrill Lynch Money Markets, DDA #3756240690. The wire should identify the name of the Fund, and should include your name and account number. Failure to submit the required information may delay investment. We urge you to make payment by wire in Federal Funds. If you do not maintain an account directly with the Fund’s transfer agent, you should contact your financial adviser.

Payment to the Transfer Agent. Payment made by check may be submitted directly by mail or otherwise to the Fund’s transfer agent. Purchase orders by mail should be sent to Financial Data Services, LLC, P.O. Box 40486, Jacksonville, Florida 32203-0486. Purchase orders sent by hand should be delivered to Financial Data Services, LLC, 4800 Deer Lake Drive East, Jacksonville, Florida 32246-6484. If you are opening a new account, you must enclose a completed Purchase Application. If you are an existing shareholder, you should enclose the detachable stub from a monthly account statement. Checks should be made payable to the Distributor. Certified checks are not necessary, but checks are accepted subject to collection at full face value in U.S. funds and must be drawn in U.S. dollars on a U.S. bank. Payments for the accounts of corporations, foundations and other organizations may not be made by third party checks. Since there is a three day settlement period applicable to the sale of most securities, delays may occur when an investor is liquidating other investments for investment in one of the Funds.

Purchases of Shares of U.S.A. Government Money Through Merrill Lynch Plans

Shares of U.S.A. Government Money are also offered to certain accounts for which Merrill Lynch acts as custodian (“Custodial Plans”).

Special purchase procedures apply in the case of the Custodial Plans. Cash balances of participants who elect to have funds automatically invested in U.S.A. Government Money will be invested as follows: Cash balances arising from the sale of securities held in the Custodial Plan account that do not settle on the day of the transaction (such as most common and preferred stock transactions) become available to the Fund and will be invested in shares of the Fund on the business day following the day that proceeds with respect thereto are received in the Custodial Plan

II-27

Table of Contents

account. Proceeds giving rise to cash balances from the sale of securities held in the Custodial Plan account settling on a same day basis and from principal repayments on debt securities held in the account become available to the Fund and will be invested in shares of the Fund on the next business day following receipt. Cash balances arising from dividends or interest payments on securities held in the Custodial Plan account or from a contribution to the Custodial Plan are invested in shares of the Fund on the business day following the date the payment is received in the Custodial Plan account.

Purchase of Shares by CMA Service Subscribers

Merrill Lynch Programs. Shares of the BIF Funds are offered to participants in the CMA service, to participants in certain other Merrill Lynch central asset account programs and to individual investors maintaining accounts directly with the Funds’ transfer agent. If you participate in the CMA service or the Merrill Lynch central asset account programs, you generally will have free cash balances invested in shares of the Fund you designated as the primary investment account (“Money Account”) as described below.

If you subscribe to the CMA service or the Merrill Lynch central asset account programs, you have the option to change the designation of your Money Account at any time by notifying your financial adviser. At that time, you may instruct your financial adviser to redeem shares of a Fund designated as the Money Account and to transfer the proceeds to the newly designated Money Account. Each BIF Fund has reserved the right to suspend or otherwise limit sales of its shares if, as a result of difficulties in obtaining portfolio securities, it is determined that it is not in the interests of the BIF Fund’s shareholders to issue additional shares.

Automatic Purchases.

(All BIF Funds): Free cash balances in certain Merrill Lynch central asset account programs may be swept into BIF Money or BIF Treasury.

Manual Purchases.

(All BIF Funds): If you subscribe to the CMA service or the Merrill Lynch central asset account programs, you may make manual investments through your financial adviser at any time in shares of a BIF Fund not selected as your Money Account. Manual purchases take effect on the day following the day the order is placed by Merrill Lynch with the Fund, except that orders involving cash deposits made on the date of a manual purchase take effect on the second business day thereafter, if they are placed with the Fund after the cashiering deadline of the Merrill Lynch office in which the deposit is made. As a result, if you enter manual purchase orders that include cash deposits made on that day after the cashiering deadline, you will not receive the daily dividend which you would have received had your order been entered prior to the deadline. In addition, manual purchases of $500,000 or more can be made effective on the same day the order is placed with Merrill Lynch provided that requirements as to timely notification and transfer of a Federal Funds wire in the proper amount are met. If you desire further information on this method of purchasing shares, you should contact your financial adviser.

All purchases of Fund shares and dividend reinvestments will be confirmed to CMA service (or other Merrill Lynch central asset account program) subscribers (rounded to the nearest share) in the monthly transaction statement provided by Merrill Lynch.

Working Capital Management Account ^® . The Working Capital Management Account ^® (“WCMA”) financial service (“WCMA service”) for corporations and other businesses provides participants a securities account (which includes all the features of a regular CMA account) plus optional lines of credit and other features. The WCMA service has sweep features and annual participation fees different from those of a CMA account. A brochure describing the WCMA service as well as information concerning charges for participation in the program is available from Merrill Lynch.

Purchase of Shares of BBIF Funds by WCMA Service Subscribers

Eligibility. Shares of the BBIF Funds are offered to certain subscribers in the WCMA service and in certain other Merrill Lynch business account programs. WCMA service or other business account program subscribers generally will have available cash balances invested in the Fund designated by the subscriber as the primary investment account (the “Primary Money Account”). A subscriber also may elect to manually invest cash balances into certain other money market funds or individual money market accounts pursuant to the Insured Savings Account ^SM .

The WCMA service and certain other Merrill Lynch business account programs have sweep features and annual participation fees different from those of a CMA account.

II-28

Table of Contents

Purchases of shares of a BBIF Fund designated as the Primary Money Account will be made pursuant to the automatic or manual purchase procedures described below.

Subscribers in the WCMA service or other business account program have the option to change the designation of their Primary Money Account at any time by notifying their Merrill Lynch financial adviser. At that time, a subscriber may instruct its financial adviser to redeem shares of a BBIF Fund designated as the Primary Money Account and to transfer the proceeds to the share class that the subscriber is eligible to own in the newly-designated Primary Money Account.

Automatic Purchases. The delay with respect to the automatic investment of cash balances in a subscriber’s account in shares of the Fund designated as the subscriber’s Primary Money Account is determined by the subscriber’s WCMA service or other business account program tier assignment. For further information regarding the timing of sweeps for each tier, a subscriber should consult with its Merrill Lynch financial adviser or the relevant service account agreement and program description.

Manual Purchases. Subscribers in the WCMA service or other business account program may make manual investments at any time in shares of a BBIF Fund not selected as that investor’s Primary Money Account. Manual purchases shall be effective on the day following the day the order is placed with Merrill Lynch, except that orders involving cash deposits made on the date of a manual purchase shall become effective on the second business day thereafter if they are placed after the cashiering deadline of the Merrill Lynch office in which the deposit is made. As a result, WCMA service or other business account program subscribers who enter manual purchase orders that include cash deposits made on that day after such cashiering deadline will not receive the daily dividend which would have been received had their orders been entered prior to the deadline. In addition, manual purchases of $1,000,000 or more can be made effective on the same day the order is placed with Merrill Lynch provided that requirements as to timely notification and transfer of a Federal Funds wire in the proper amount are met. A WCMA service or other business account program subscriber desiring further information on this method of purchasing shares should contact its Merrill Lynch financial adviser.

All purchases of the BBIF Funds’ shares and dividend reinvestments will be confirmed to WCMA service or other business account program subscribers (rounded to the nearest share) in the monthly transaction statement.

BBIF Multiple Class Structure. Each BBIF Fund offers four share classes, each with its own ongoing fees, expenses and other features. A subscriber must be eligible to own a particular class of shares. Reference is made to “Account Information — BBIF Multiple Class Structure” and “— How to Choose the Share Class that Best Suits Your Needs” in the Prospectus for certain information with respect to the eligibility requirements to own Class 1, Class 2, Class 3 and Class 4 shares of each BBIF Fund.

Each Class 1, Class 2, Class 3 or Class 4 share of a BBIF Fund represents an identical interest in that Fund and has the same rights, except that each class of shares bears to a different degree the expenses of the service fees and distribution fees and the additional incremental transfer agency costs resulting from the conversion of shares. See “Account Information — BBIF Multiple Class Structure” and “— How to Choose the Share Class that Best Suits Your Needs” in the Prospectus. The distribution fees and service fees that are imposed on each class of shares, are imposed directly against that class and not against all assets of the BBIF Fund and, accordingly, the differing fee rate for each class does not affect the net asset value or have any impact on any other class of shares. Dividends paid by a BBIF Fund for each class of shares are calculated in the same manner at the same time and differ only to the extent that service fees and distribution fees and any incremental transfer agency costs relating to a particular class are borne exclusively by that class. Each class may be subject to monthly automatic conversions. See “Your Account — BBIF Multiple Class Structure” in the Prospectus.

WCMA subscribers should understand the purpose and function of different fee rates with respect to each class, which is to provide for the financing of the distribution of each class of shares of the BBIF Funds. Class 4 shares bear the lowest service and distribution fees because larger accounts cost less to service and distribute and those economies are passed on to the subscriber. Class 1 shares bear the highest service and distribution fees because smaller accounts cost more to service and distribute and there are fewer economies to pass on to the subscriber. The distribution-related revenues paid with respect to a class will not be used to finance the distribution expenditures of another class. Sales personnel may receive different compensation for selling different classes of shares.

Purchase of Shares of Retirement Reserves

Purchases of Retirement Reserves shares by pension, profit-sharing and annuity plans are made by the trustee or sponsor of such plan by payments directly to Merrill Lynch.

II-29

Table of Contents

Retirement Reserves offers two classes of shares, Class I and Class II shares. Each Class I and Class II share of the Fund represents an identical interest in the investment portfolio of the Fund, except that Class II shares bear the expenses of the ongoing distribution fees.

Class I shares of Retirement Reserves are offered to certain Custodial Plans with an active custodial retirement account as of September 30, 1998, any Custodial Plan purchasing shares of the Fund through a Merrill Lynch fee-based program, certain independent pension, profit-sharing, annuity and other qualified plans, and qualified tuition programs established under Section 529 of the Code (collectively, the “Plans”).

Class II shares are offered to any Plan that did not have an active custodial retirement account as of September 30, 1998 and does not otherwise qualify to purchase Class I shares.

There are nine types of Custodial Plans: (1) a traditional IRA, (2) a Roth IRA, (3) an IRRA ^® , (4) a SEP, (5) an SRA, (6) a Basic ^SM (Keogh Plus) profit sharing plan and (7) a Basic ^SM (Keogh Plus) money purchase pension plan (together with the profit sharing plan, the “Basic ^SM Plans”), (8) a 403(b)(7) RSA, and (9) an education account. Although the amount that may be contributed to a Plan account in any one year is subject to certain limitations, assets already in a Plan account may be invested in the Fund without regard to such limitations.

If you are considering transferring a tax-deferred retirement account such as an IRA from Merrill Lynch to another securities dealer or other financial intermediary, you should be aware that if the firm will not take delivery of shares of Retirement Reserves, you must either redeem the shares so that the cash proceeds can be transferred to the account at the new firm, or you must continue to maintain a retirement account at Merrill Lynch for those shares.

Plan Investments. If you are a Plan participant, an investment in shares of Retirement Reserves can be made as follows:

•	If participants elect to have their contributions invested in the Fund, the contributions will be invested automatically on the business day following the date they are received in the account. There will be no minimum initial or subsequent purchase requirement pursuant to these types of plans. The amount that may be contributed to a Plan in any one year is subject to certain limitations under the Code; however, assets already in a Plan account may be invested without regard to such limitations on contributions. Cash balances of less than $1.00 will not be invested.
•	Participants in Custodial Plans who opened their accounts prior to December 6, 1999 had two options concerning cash balances that may arise in their accounts. First, participants could have elected to have such balances automatically invested on a daily basis in shares of the Fund or, in some cases, in another money market mutual fund advised by the Manager. Second, participants (except for RSAs) could have elected to have such balances deposited in an FDIC-insured money market account with one or more commercial banks. After December 6, 1999, certain Custodial Plan accounts no longer have the first option for cash balances.
•	Participants who have elected to have cash balances automatically invested in the Fund will have such funds invested as follows: cash balances arising from the sale of securities held in the Plan account that do not settle on the day of the transaction (such as most common and preferred stock transactions) will be invested in shares of the Fund on the business day following the day that the proceeds are received in the Plan account. Proceeds giving rise to cash balances from the sale of securities held in the Plan account settling on a same day basis and from principal repayments on debt securities held in the account will be invested in shares of the Fund on the next business day following receipt. Cash balances arising from dividends or interest payments on securities held in the Plan account or from a contribution to the Plan are invested in shares of the Fund on the business day following the date the payment is received in the Plan account.

All purchases and redemptions of Fund shares and dividend reinvestments are confirmed (rounded to the nearest share) to participants in Plans in the monthly or quarterly statement sent to all participants in these Plans. The Fund and the Distributor have received an exemptive order from the Commission that permits the Fund to omit sending out more frequent confirmations with respect to certain transactions. These transactions include purchases resulting from automatic investments in shares of the Fund and redemptions that are effected automatically to purchase other securities that the participant has selected for investment in his account. Shareholders who are not participants in the Plans receive quarterly statements reflecting all purchases, redemptions and dividend reinvestments of Fund shares.

You should read materials concerning the Plans, including copies of the Plans and the forms necessary to establish a Plan account, which are available from Merrill Lynch. You should read such materials carefully before establishing a Plan account and should consult with your attorney or tax advisor to determine if any of the Plans are suited to your needs and circumstances. The laws applicable to the Plans, including the Employee Retirement Income

II-30

Table of Contents

Security Act of 1974, as amended (“ERISA”), and the Code, are complex and include a variety of transitional rules, which may be applicable to some investors. These laws should be reviewed by your attorney to determine their applicability. You are further advised that the tax treatment of the Plans under applicable state law may vary.

Purchase of Shares of Summit Cash Reserves

Exchange Privilege. Investor A shareholders of Summit Cash Reserves who acquired their shares upon an exchange from Investor A or Institutional Shares of certain affiliated funds will have an exchange privilege with Investor A or Institutional Shares of certain affiliated funds. Shareholders may exchange Investor A Shares of the Fund for Institutional Shares of one of the affiliated funds if the shareholder holds any Institutional Shares of that affiliated fund in the account in which the exchange is to be made at the time of the exchange or is otherwise eligible to purchase Institutional Shares of such affiliated fund. Otherwise Investor A Shares will automatically be purchased.

Eligible institutional investors include: employees of BlackRock, Merrill Lynch, PNC and Directors of any BlackRock-advised funds; customers of broker-dealers and agents that have established a servicing relationship with the Fund on behalf of their customers; investors who currently own Institutional Shares in a shareholder account are entitled to purchase additional Institutional Shares of the Fund in that account; institutional and individual retail investors with a minimum investment of $2 million; certain qualified retirement plans; investors in selected fee based programs; registered investment advisers with a minimum investment of $250,000; Trust departments of PNC Bank and Merrill Lynch Trust Company and their affiliates for whom they (i) act in a fiduciary capacity (excluding participant directed employee benefit plans); (ii) otherwise have investment discretion; (iii) act as custodian for at least $2 million in assets; unaffiliated banks, thrifts or trust companies that have agreements with a Distributor; and holders of certain Merrill Lynch sponsored unit investment trusts (UITs) who reinvest dividends received from such UITs in shares of the Fund.

If a holder of Investor A Shares of the Fund subsequently exchanges back into the same class of shares of the original affiliated fund it will do so without paying any sales charge. If a holder of Investor A Shares of the Fund exchanges into Investor A or Institutional Shares of another affiliated fund, the holder will be required to pay a sales charge equal to the difference, if any, between the sales charge previously paid on the shares of the original affiliated fund and the sales charge payable at the time of the exchange on the shares of the new affiliated fund.

Investor B shareholders of the Fund who acquired their shares upon an exchange from Investor B or Investor C Shares of certain affiliated funds will have an exchange privilege with Investor B or Investor C Shares of certain affiliated funds. A holder of Investor B Shares of the Fund may subsequently exchange back into the original affiliated fund. When a shareholder exchanges Investor B or Investor C Shares of an affiliated fund for Investor B Shares of the Fund, the period of time that the shareholder holds the Investor B Shares of the Fund will count towards satisfaction of the holding period requirement for purposes of reducing the CDSC relating to the Investor B or Investor C Shares acquired upon exchange of the Investor B Shares of the Fund. With respect to exchanges of Investor B Shares of an affiliated fund into Investor B Shares of the Fund, the period of time the Investor B Shares of the affiliated fund are held will count towards satisfaction of the conversion period (the length of time until the Investor B Shares acquired upon exchange of the Investor B Shares of the Fund are automatically converted into Investor A Shares). Conversely, the period of time that a shareholder has held the shares of an affiliated fund or a fund participating in the Exchange Program will count towards the satisfaction of the conversion period under which Investor B Shares of the Fund convert to Investor A Shares of the Fund.

If Investor B Shares are redeemed from the Fund and not exchanged into shares of an affiliated fund, a CDSC will be charged to the extent it would have been charged on a redemption of shares from the original affiliated fund.

It is contemplated that the exchange privilege may be applicable to other new mutual funds whose shares are distributed by the Distributor.

Under the exchange privilege, exchanges are made on the basis of the relative net asset values of the shares being exchanged. Shares issued pursuant to dividend reinvestment are sold on a no-load basis in each of the affiliated funds. For purposes of the exchange privilege, dividend reinvestment shares shall be deemed to have been sold with a sales charge equal to the sales charge previously paid on the shares on which the dividend was paid. Based on this formula an exchange of Investor A Shares of the Fund for Investor A or Institutional Shares of an affiliated fund generally will require the payment of a sales charge equal to the difference, if any, between the sales charge previously paid on the Institutional or Investor A Shares originally exchanged for Investor A Shares of the Fund and the sales charge that may be payable at the time of the exchange on the Institutional or Investor A Shares of the affiliated fund to be acquired.

II-31

Table of Contents

Exchange Program. The Fund participates in an exchange program with certain non-money market open-end management investment companies that are (i) distributed by a selected securities dealer that is an affiliate of the Distributor, (ii) not affiliated funds, and (iii) not distributed by the Distributor (each referred to as a “Participating Fund”) (the “Exchange Program”). Exchanges may be made into Investor A or Investor B Shares of the Fund at net asset value without the imposition of a front-end sales charge (“sales charge”) or CDSC. Shares of a Participating Fund that are subject to a sales charge will be exchanged for Investor A Shares of the Fund without the imposition of a sales charge. The holder of Investor A Shares of the Fund may subsequently either exchange back into the same class of shares of the Participating Fund without incurring any sales charge or exchange into shares of another Participating Fund subject to a sales charge in the same fund complex as the original Participating Fund by remitting an amount equal to the difference, if any, between the sales charge previously paid on the shares of the original Participating Fund and the sales charge payable at the time of the exchange on the shares of the new Participating Fund.

Exchanges may be made into Investor B Shares of the Fund at net asset value without the imposition of a sales charge. Shares of Participating Funds subject to a CDSC will be exchanged for Investor B Shares of the Fund without the payment of a CDSC that might otherwise be due on redemption of the Participating Fund shares. The holder of such Investor B Shares of the Fund may subsequently either exchange back into the same class of shares of the Participating Fund or exchange into shares of another Participating Fund in the same fund complex as the original Participating Fund. Upon such exchange, the holder of the Investor B Shares of the Fund will receive credit toward reduction of the CDSC that would have been due on the Participating Fund shares for the time period during which the Investor B Shares of the Fund were held. This period of time will also count towards satisfaction of any conversion period applicable to the Participating Fund shares. If holders of the Investor B Shares of the Fund redeem those shares instead of exchanging back into shares of the original Participating Fund or of another Participating Fund in the same fund complex, CDSC payments, if any, will be assessed based upon the combined holding period for the Participating Fund shares and the Fund shares.

The Participating Funds may impose administrative and/or redemption fees on an exchange transaction with the Fund. There will be no sales charge on exchange transactions into the Fund. The Exchange Program may be modified or terminated at any time in accordance with the rules of the Commission.

A Participating Fund may modify or terminate the terms of its involvement in the Exchange Program at any time in accordance with the rules of the Commission.

Before effecting an exchange, shareholders of the Fund should obtain a currently effective prospectus of the affiliated fund or participating Fund into which the exchange is to be made for information regarding the fund and for further details regarding such exchange.

To effect an exchange, shareholders should contact their financial adviser, selected securities dealer or other financial intermediary, who will advise the Fund of the exchange, or write to the Fund’s transfer agent requesting that the exchange be effected. Shareholders of Participating Funds and certain affiliated funds with shares for which certificates have not been issued may effect an exchange by wire through their securities dealers. The Exchange Program or the exchange privilege may be modified or terminated at any time in accordance with the rules of the Commission. There is currently no limitation on the number of times a shareholder may effect an exchange into the Fund either through the exchange privilege or the Exchange Program; however, the Fund reserves the right to limit the number of times an investor may effect an exchange. Certain Participating Funds and affiliated funds may suspend the continuous offering of their shares at any time and thereafter may resume such offering from time to time. The Exchange Program and the exchange privilege are available only to U.S. shareholders in states where the exchange legally may be made.

An exchange pursuant to the exchange privilege or pursuant to the Exchange Program is treated as a sale of the exchanged shares and a purchase of the new shares for Federal income tax purposes. In addition, an exchanging shareholder of any of the funds may be subject to backup withholding unless such shareholder certifies under penalty of perjury that the taxpayer identification number on file with any such fund is correct, and that he or she is not otherwise subject to backup withholding. See “Dividends and Taxes — Taxes.”

Purchase of Shares of the BlackRock Funds Portfolio

The BlackRock Funds Portfolio has authorized one or more brokers and/or financial institutions (“Authorized Persons”) to receive on its behalf purchase and redemption orders that are in “good form” in accordance with the policies of those Authorized Persons. Such Authorized Persons are authorized to designate other intermediaries to receive purchase and redemption orders on the Fund’s behalf, and the Fund will be deemed to have received a

II-32

Table of Contents

purchase or redemption order when an Authorized Persons or, if applicable, such Authorized Person’s authorized designee, receives the order. Such customer orders will be priced at the Fund’s net asset value next computed after they are received by an Authorized Person or such Authorized Person’s authorized designee. Financial institutions may include retirement plan service providers who aggregate purchase and redemption instructions received from numerous retirement plans or plan participants.

Investor Shares

Purchase of Shares. The minimum investment for the initial purchase of shares is $1,000. There is no investment minimum for employer-sponsored retirement plans (not including SEP IRAs, SIMPLE IRAs or SARSEPs). There is no investment minimum for certain fee-based programs. There is a $50 minimum for subsequent investments (with the exception of certain employer-sponsored retirement plans which may have a lower minimum). Purchases through the Automatic Investment Plan are subject to a lower initial purchase minimum. In addition, the minimum initial investment for employees of the Fund, the Fund’s Manager, sub-advisor, BRIL or transfer agent or employees of their affiliates is $100, unless payment is made through a payroll deduction program in which case the minimum investment is $25.

Purchases Through Brokers. It is the responsibility of brokers to transmit purchase orders and payment on a timely basis. Generally, if payment is not received within the period described in the prospectuses, the order will be canceled, notice thereof will be given, and the broker and its customers will be responsible for any loss to the Fund or its shareholders. Orders of less than $500 may be mailed by a broker to the transfer agent.

Other Purchase Information. Shares of the Fund are sold on a continuous basis by BRIL as distributor. BRIL maintains its principal offices at 40 East 52nd Street, New York, New York 10022. Purchases may be effected on weekdays on which the NYSE is open for business (a “Business Day”). Payment for orders which are not received or accepted will be returned after prompt inquiry. The issuance of shares is recorded on the books of the Fund. No certificates will be issued for shares. Payments for shares of the Fund may, in the discretion of the Fund’s Manager, be made in the form of securities that are permissible investments for the Fund. The Fund reserves the right to reject any purchase order, to modify or waive the minimum initial or subsequent investment requirement and to suspend and resume the sale of any share class of the Fund at any time.

Shareholder Features.

Exchange Privilege. Unless an exemption applies, a front-end sales charge will be charged in connection with exchanges of Investor A Shares of the BlackRock Funds Portfolio for Investor A Shares of one of the non-money market portfolios of the Trust (each a “Non-Money Market Portfolio”). Exchanges of Investor B or Investor C Shares of the Fund for Investor B or Investor C Shares of a Non-Money Market Portfolio of the Trust will be exercised at NAV. However, a CDSC will be charged in connection with the redemption of the Investor B or Investor C Shares of the Non-Money Market Portfolio received in the exchange.

Investor A Shares of the Fund that were (1) acquired through the use of the exchange privilege and (2) can be traced back to a purchase of shares in one or more investment portfolios of the Fund for which a sales charge was paid, can be exchanged for Investor A Shares of the Fund subject to a sales charge.

A shareholder wishing to make an exchange may do so by sending a written request to the Fund at the following address: BlackRock, P.O. Box 9819, Providence, RI 02940-8019. Shareholders are automatically provided with telephone exchange privileges when opening an account, unless they indicate on the Application that they do not wish to use this privilege. To add this feature to an existing account that previously did not provide this option, a request must be made in writing or by telephone. Once this election has been made, the shareholder may simply contact the Fund by telephone at (800) 441-7762 to request the exchange. During periods of substantial economic or market change, telephone exchanges may be difficult to complete and shareholders may have to submit exchange requests in writing.

If the exchanging shareholder does not currently own shares of the investment portfolio whose shares are being acquired, a new account will be established with the same registration, dividend and capital gain options and broker of record as the account from which shares are exchanged, unless otherwise specified in writing by the shareholder with all signatures guaranteed by an eligible guarantor institution as defined below. In order to participate in the Automatic Investment Program or establish a Systematic Withdrawal Plan for the new account, however, an exchanging shareholder must file a specific written request.

Any share exchange must satisfy the requirements relating to the minimum initial investment requirement, and must be legally available for sale in the state of the investor’s residence. For Federal income tax purposes, a share

II-33

Table of Contents

exchange is a taxable event and, accordingly, a capital gain or loss may be realized. Before making an exchange request, shareholders should consult a tax or other financial adviser and should consider the investment objective, policies and restrictions of the investment portfolio into which the shareholder is making an exchange. Brokers may charge a fee for handling exchanges.

The Fund reserves the right to suspend, modify or terminate the exchange privilege at any time. Notice will be given to shareholders of any material modification or termination except where notice is not required. The Fund reserves the right to reject any telephone exchange request. Telephone exchanges may be subject to limitations as to amount or frequency, and to other restrictions that may be established from time to time to ensure that exchanges do not operate to the disadvantage of any portfolio or its shareholders. The Fund, the Administrators and BRIL will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. The Fund, the Trust, the administrators and BRIL will not be liable for any loss, liability, cost or expense for acting upon telephone instructions reasonably believed to be genuine in accordance with such procedures.

By use of the exchange privilege, the investor authorizes the Fund’s transfer agent to act on telephonic or written exchange instructions from any person representing him– or herself to be the investor and believed by the Fund’s transfer agent to be genuine. The records of the Fund’s transfer agent pertaining to such instructions are binding. The exchange privilege may be modified or terminated at any time upon 60 days’ notice to affected shareholders. The exchange privilege is only available in states where the exchange may legally be made.

The redemption of shares of one fund and the subsequent investment in another fund generally will be treated as two separate transactions. Therefore, a front-end sales charge will be imposed (unless an exemption applies) on the purchase of Investor A or Investor A1 Shares of a Non-Money Market Portfolio with the proceeds of a redemption of Investor Shares of the BlackRock Funds Portfolio. In addition, when Investor Shares of the BlackRock Funds Portfolio are redeemed and the proceeds are used to purchase Investor B, Investor B1, Investor B2, Investor C, Investor C1 or Investor C2 Shares of a Non-Money Market Portfolio, a contingent deferred sales charge will be imposed (unless an exemption applies) when the Investor B Shares or Investor C Shares of the Non-Money Market Portfolio are redeemed.

If the Fund imposes a liquidity fee or a redemption gate, you will not be permitted to exchange into or out of the Fund until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted. Please see the Fund’s prospectus for more information.

Automatic Investment Plan (“AIP”). Certain shareholders may arrange for periodic investments in the Fund through automatic deductions from a checking or savings account by completing the AIP Application which may be obtained from the Fund at (800) 441-7762, or online at www.blackrock.com. The minimum pre-authorized investment amount is $50 per Fund.

If the Fund imposes a liquidity fee or a redemption gate, you will not be permitted to automatically invest through the AIP until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted. Please see the Fund’s prospectus for more information.

Systematic Withdrawal Plan (“SWP”). The BlackRock Funds Portfolio offers a Systematic Withdrawal Plan to shareholders who wish to receive regular distributions from their accounts. Upon commencement of the SWP, the account must have a current value of $10,000 or more in the Fund. Shareholders may elect to receive automatic cash payments of $50 or more at any interval. You may choose any day for the withdrawal. If no day is specified, the withdrawals will be processed on the 25th day of the month or, if such day in not a Business Day, on the prior Business Day and are paid promptly thereafter. An investor may utilize the SWP by completing the Systematic Withdrawal Plan Application Form which may be obtained by calling the Fund or by visiting our website at www.blackrock.com.

Shareholders should realize that if withdrawals exceed income dividends their invested principal in the account will be depleted. To participate in the SWP, shareholders must have their dividends automatically reinvested. Shareholders may change or cancel the SWP at any time, upon written notice to the Fund, or by calling the Fund at (800) 441-7762.

For this reason, a shareholder may not participate in the Automatic Investment Plan (see “Services for Shareholders — Automatic Investment Plan” in the Fund’s Prospectus) and the Systematic Withdrawal Plan at the same time.

If the Fund imposes a liquidity fee or redemption gate, you will not be permitted to systematically withdraw your shares through the SWP until the Fund has notified shareholders that the liquidity fee or redemption gate has been lifted. Please see the Fund’s prospectus for more information.

Dividend Allocation Plan. The Dividend Allocation Plan allows shareholders to elect to have all their dividends and any other distributions from the BlackRock Funds Portfolio or any Eligible Fund (which includes the Fund and other funds as designated by BRIL from time to time) automatically invested at net asset value in one other such Eligible Fund designated by the shareholder, provided the account into which the dividends and distributions are directed is initially funded with the requisite minimum amount.

Institutional Shares

Purchase of Shares. The BlackRock Funds Portfolio offers Institutional Shares as described in the Fund’s Prospectus. In addition, the following investors may purchase Institutional Shares, provided that the beneficial owners of such shares are natural persons: employees, officers and directors/trustees of BlackRock, Inc., BlackRock Funds, Bank of America Corporation (“BofA Corp.”), The PNC Financial Services Group Inc., Barclays PLC or their respective affiliates and immediate family members of such persons, if they open an account directly with BlackRock; individuals with a minimum initial investment of $2 million who may purchase shares of the Fund through a financial intermediary that has entered into an agreement with the Distributor to purchase such shares; employer-sponsored retirement plans (which, for this purpose, do not include SEP IRAs, SIMPLE IRAs or SARSEPs) and state sponsored 529 college savings plans, each of which may purchase shares of the Fund through a financial intermediary that has entered into an agreement with the Distributor to purchase such shares; investors of financial intermediaries that: (i) charge such investors a fee for advisory, investment consulting, or similar services or (ii) have entered into an agreement with the Distributor to offer Institutional Shares through a no-load program or investment platform, in each case, with no minimum initial investment; clients investing through financial intermediaries that have entered into an agreement with the Distributor to offer such shares on a platform that charges a transaction based sales commission outside of the Fund, with a minimum initial investment of $1,000; clients of the trust departments of PNC Bank and Bank of America, N.A. and their affiliates for whom they (i) act in a fiduciary capacity (excluding participant directed employee benefit plans), (ii) otherwise have investment discretion, or (iii) act as custodian for at least $2 million in assets; and holders of certain BofA Corp. sponsored unit investment trusts (UITs) who reinvest dividends received from such UITs in shares of the Fund.

Institutional Shares of the Fund may be purchased by customers of broker-dealers and agents which have established a servicing relationship with the Fund on behalf of their customers. These broker-dealers and agents may impose additional or different conditions on the purchase or redemption of Fund shares by their customers and may charge their customers transaction, account or other fees on the purchase and redemption of Fund shares. Each broker-dealer or agent is responsible for transmitting to its customers a schedule of any such fees and information regarding any additional or different conditions regarding purchases and redemptions. Shareholders who are customers of such broker-dealers or agents should consult them for information regarding these fees and conditions.

Except as otherwise specified in the Fund’s Prospectus, payment for Institutional Shares must normally be made in Federal funds or other immediately available funds by the close of the federal funds wire (normally 6:00 p.m. (Eastern time)). Payment may also, in the discretion of the Fund, be made in the form of securities that are permissible investments for the Fund. If payment for a purchase order is not received by the prescribed time, an investor may be liable for any resulting losses or expenses incurred by the Fund.

Financial intermediaries may, in connection with a change in account type or otherwise in accordance with a financial intermediary’s policies and procedures, exchange shares of the Fund from one class of shares to another class of shares of the Fund, provided that the exchanged shares are not subject to a contingent deferred sales charge and that shareholders meet eligibility requirements of the new share class.

DCC&S. Qualified Plans may be able to invest in shares of the BlackRock Funds Portfolio through the Defined Contribution Clearance and Settlement System (“DCC&S”) of the National Securities Clearing Corporation. Institutions qualifying to trade on DCC&S include broker/dealers, trust companies and third party administrators. Please contact the Fund for information on agreements, procedures, sales charges and fees related to DCC&S transactions.

Distribution and/or Shareholder Servicing Plans

Each Fund has entered into a distribution agreement with BlackRock Investments, LLC (previously defined as the “Distributor”) under which the Distributor, as agent, offers shares of each Fund on a continuous basis. The Distributor has agreed to use appropriate efforts to effect sales of the shares, but it is not obligated to sell any particular amount of shares. The Distributor’s principal business address is 40 East 52nd Street, New York, NY 10022. The Distributor is an affiliate of BlackRock.

II-35

Table of Contents

Each Fund has adopted a shareholder servicing plan and/or a distribution plan or plans (in the case of Retirement Reserves, with respect to Class II shares only and with respect to Summit Cash Reserves with respect to Investor B Shares only) (each, a “Distribution Plan”) in compliance with Rule 12b-1 under the Investment Company Act. Each Fund other than Retirement Reserves and the BBIF Funds is authorized to pay the Distributor a fee at an annual rate based on the average daily net asset value of Fund accounts maintained through the Distributor. Retirement Reserves pays the Distributor a fee at an annual rate based on the average daily net assets attributable to Class II shares maintained through the Distributor. The Distribution Plan for each class of shares of the BBIF Funds provides that the Funds pay the Distributor a service fee relating to the shares of the relevant class, accrued daily and paid monthly, at an annual rate based on the average daily net assets of a BBIF Fund attributable to Class 1, Class 2, Class 3 and Class 4 shares. The service fee is not compensation for the administrative and operational services rendered to shareholders by affiliates of the Manager that are covered by any other agreement between each Fund and the Manager. Each class has exclusive voting rights with respect to the Distribution Plan adopted with respect to such class pursuant to which service and/or distribution fees are paid. The fee paid by each Fund other than Retirement Reserves and the BBIF Funds compensates the Distributor for providing, or arranging for the provision of, shareholder servicing and sales and promotional activities and services with respect to shares of each Fund. The Distributor then determines, based on a number of criteria, how to allocate such fee among financial advisers, selected dealers and affiliates of the Distributor. The fee paid by Retirement Reserves compensates the Distributor for the expenses associated with marketing activities and services related to Class II shares. The BBIF Distribution Plans for the Class 1, Class 2, Class 3 and Class 4 shares each provide that a Fund also pays the Distributor a distribution fee based on the average daily net assets of the Fund attributable to the shares of the relevant class. These fees are set forth in the BBIF Fund Prospectus.

Each Fund’s Distribution Plans are subject to the provisions of Rule 12b-1 under the Investment Company Act. In their consideration of a Distribution Plan, the Trustees must consider all factors they deem relevant, including information as to the benefits of the Distribution Plan to the Fund and the related class of shareholders. In approving a Distribution Plan in accordance with Rule 12b-1, the non-interested Trustees concluded that there is reasonable likelihood that the Distribution Plan will benefit the Fund and its related class of shareholders.

Each Distribution Plan provides that, so long as the Distribution Plan remains in effect, the non-interested Trustees then in office will select and nominate other non-interested Trustees. Each Distribution Plan can be terminated at any time, without penalty, by the vote of a majority of the non-interested Trustees or by the vote of the holders of a majority of the outstanding related class of voting securities of a Fund. A Distribution Plan cannot be amended to increase materially the amount to be spent by the Fund without the approval of the related class of shareholders. All material amendments are required to be approved by the vote of Trustees, including a majority of the non-interested Trustees who have no direct or indirect financial interest in the Distribution Plan, cast in person at a meeting called for that purpose. Rule 12b-1 further requires that each Fund preserve copies of each Distribution Plan and any report made pursuant to such plan for a period of not less than six years from the date of the Distribution Plan or such report, the first two years of which should be stored in an easily accessible place.

Among other things, each Distribution Plan provides that the Trustees will review quarterly reports of the shareholder servicing and/or distribution expenditures paid to the Distributor. With respect to each Fund other than the BlackRock Funds Portfolio, Retirement Reserves and Summit Cash Reserves, in the event that the aggregate payments received by the Distributor under the Distribution Plan in any year exceeds the amount of the distribution and shareholder servicing expenditures incurred by the Distributor, the Distributor is required to reimburse the Fund the amount of such excess. With respect to Retirement Reserves, payments under the Class II Distribution Plan are based on a percentage of average daily net assets attributable to Class II shares, regardless of the amount of expenses incurred. As a result, the distribution related revenues from the Distribution Plan with respect to Retirement Reserves may be more or less than distribution related expenses of the Class II shares. Information with respect to the distribution-related revenues and expenses is presented to the Trustees for their consideration on a quarterly basis. Distribution-related expenses consist of financial adviser compensation, branch office and regional operation center selling and transaction processing expenses, advertising, sales promotion and marketing expenses and interest expense. With respect to Retirement Reserves, the distribution-related revenues paid with respect to one class will not be used to finance the distribution expenditures of another class. Sales personnel may receive different compensation for selling different classes of shares.

See Part I, Section V “Distribution Related Expenses” of each Fund’s SAI for information relating to the fees paid by your Fund to the Distributor under each Distribution Plan during the Fund’s most recent fiscal year.

Limitations on the Payment of Asset Based Sales Charges. The maximum sales charge rule in the Conduct Rules of the NASD imposes a limitation on certain asset-based sales charges such as the distribution fee borne by

II-36

Table of Contents

each class of shares in the case of the BBIF Funds, and Class II shares in the case of Retirement Reserves. The maximum sales charge rule limits the aggregate of distribution fee payments payable by a Fund to (i) 7.25% of eligible gross sales of the applicable shares (excluding shares issued pursuant to dividend reinvestments and exchanges), plus (ii) interest on the unpaid balance for the applicable shares at the prime rate plus 1% (the unpaid balance being the maximum amount payable minus amounts received from the payment of the distribution fee).

In the case of the BBIF Funds, the Distributor has voluntarily agreed to waive interest charges on the unpaid balance in excess of 0.50% of eligible gross sales. Consequently, the maximum amount payable to the Distributor (referred to as the “voluntary maximum”) is 7.75% of eligible gross sales. The Distributor retains the right to stop waiving the interest charges at any time. To the extent payments would exceed the voluntary maximum, a BBIF Fund will not make further payments of the distribution fee with respect to its shares; however, a BBIF Fund will continue to make payments of the service fee. In certain circumstances the amount payable pursuant to the voluntary maximum may exceed the amount payable under the NASD formula. In such circumstances, payment in excess of the amount payable under the NASD formula will not be made.

Other Payments by the Fund

In addition to fees a Fund pays to its transfer agent, BlackRock, on behalf of a Fund, may enter into non-Plan agreements with affiliated and unaffiliated brokers, dealers, financial institutions, insurance companies, retirement plan record-keepers and other financial intermediaries (including BlackRock, PNC and their affiliates, and entities that may also be serving as distribution agents) (collectively, “Service Organizations”) pursuant to which the Fund will pay a Service Organization for administrative, networking, recordkeeping, sub-transfer agency, sub-accounting and/or shareholder services. These non-Plan payments are generally based on either (1) a percentage of the average daily net assets of Fund shareholders serviced by a Service Organization or (2) a fixed dollar amount for each account serviced by a Service Organization. The aggregate amount of these payments may be substantial.

Additional Payments by BlackRock

From time to time, BlackRock, BRIL and/or their affiliates (referred to in this section collectively as “BlackRock”) may compensate Service Organizations for the sale and distribution of shares of a Fund or for services to a Fund and its shareholders. A Service Organization may perform these services itself or may arrange for a third party to perform them. These payments, which are not made pursuant to a Plan or otherwise paid by a Fund, are referred to as “Additional Payments” herein.

Additional Payments are made from BlackRock’s own assets (which may come directly or indirectly from fees paid by a Fund to BlackRock for various services, such as investment advisory services). These payments are not an additional charge to a Fund or its shareholders and do not change the price paid by shareholders for the purchase of a Fund’s shares or the amount a Fund receives as proceeds from such purchases. Additional Payments made to Service Organizations are in addition to any distribution or shareholder servicing fees paid under any Plan of any Fund, any sales charges, commissions or other concessions described in the Prospectuses or this SAI, and any administrative, networking, recordkeeping, sub-transfer agency or sub-accounting fees payable by a Fund. Pursuant to applicable FINRA regulations, the details of certain of these payments, including the Service Organizations receiving such payments in connection with the sale and distribution of Fund shares, are required to be disclosed. While FINRA regulations limit the sales charges that shareholders may bear, there are no limits with regard to the amounts that BlackRock may pay out of its own assets.

Additional Payments may be made as a fixed dollar amount, may be based on the number of customer accounts maintained by a Service Organization, may be based on a percentage of the value of shares sold to, or held by, customers of the Service Organization involved, or may be calculated on another basis.

BlackRock negotiates Additional Payments with each Service Organization on an individual basis. Additional Payments may be different for different Service Organizations, and some Service Organizations may be paid pursuant to more than one of the calculations described above. Not all Service Organizations receive Additional Payments. Sales-based payments primarily create incentives to make new sales of shares of the Fund, and asset-based payments primarily create incentives to retain previously sold shares of the Fund. The level of payments made to these Service Organizations in any year will vary and may be limited to specific Funds or share classes. In certain cases, these payments may be subject to certain minimum payment levels.

The aggregate amount of Additional Payments made by BlackRock may be substantial and may be significant to certain Service Organizations. The categories of Additional Payments listed below are not mutually exclusive. The

II-37

Table of Contents

same Service Organization, or one or more of its affiliates, may receive payments under more than one category of Additional Payments.

A. Distribution and Marketing Support

Additional Payments may be made by BlackRock for distribution and marketing support activities. These payments may take the form of, among other things, “due diligence” payments for a Service Organization’s examination of a Fund; payments for providing extra employee training and information relating to a Fund; fees for access (in some cases on a preferential basis) to the Service Organization’s registered representatives, salespersons or other personnel, including at sales meetings and conferences; “shelf space” payments for placing the Fund on the Service Organization’s platform(s); “listing” fees for the placing of the Fund on a dealer’s list (which may be a preferred or recommended list) of mutual funds available for purchase by its customers or in certain sales programs from time to time; fees for providing assistance in promoting the sale of the Fund’s shares (which may include promotions in communications with the Service Organization’s customers, registered representatives, salespersons and/or other personnel); payments for the sale of shares and/or the maintenance of share balances; transaction fees (also referred to as “ticket charges”); and payments for infrastructure support. These payments normally will not exceed the sum of (a) 0.25% of such year’s Fund sales by that Service Organization, and (b) 0.21% of the assets attributable to that Service Organization invested in a Fund.

Certain Funds and BlackRock have entered into distribution agreements with UBS AG whereby UBS AG may, in certain circumstances, sell certain shares of the Funds in certain jurisdictions. The level of payments made to UBS AG in any year for the sale and distribution of a Fund’s shares will vary and normally will not exceed the sum of the shareholder servicing fee payable on the assets attributable to UBS AG plus an additional fee equal to a percentage of such assets which shall range up to 0.25%.

B. Shareholder Services

Many Fund shares are owned or held by Service Organizations for the benefit of their customers. In these situations, a Fund may not maintain accounts in the name of the customers, and Service Organizations may perform some of the functions for these customers’ accounts that the transfer agent would have performed if the accounts had been in the customers’ names on the Fund’s books. Such services include sub-accounting services, shareholder servicing and transaction processing services and are sometimes referred to as “recordkeeping,” “sub-transfer agency,” “sub-accounting,” “networking” and/or “administrative” services. Additional Payments may exceed amounts that would be earned on these assets by the transfer agent for the performance of these or similar services. These Additional Payments made by BlackRock are in addition to any transfer agent, shareholder servicing and transaction processing fees paid by a Fund, as applicable.

BlackRock has entered into an arrangement with PNC Bank whereby PNC Bank provides administration services to certain Funds for the assets it holds in such Funds, and BlackRock and/or the Funds in return pays monthly fees to PNC Bank. These fees, which are subject to negotiation, will not exceed 0.07% for assets in certain money market funds, 0.20% for assets in certain fixed income funds, 0.25% for assets in certain equity funds and 0.05% for assets in certain index funds.

C. Service Organizations Receiving Additional Payments

As of the date of this SAI, the Service Organizations listed below, and, in some cases, certain of the Service Organization’s affiliates, may be receiving one or more types of Additional Payments. This list may change over time, and BlackRock may pay Service Organizations or their affiliates additional types of Additional Payments in the future. Please contact your Service Organization to determine whether it or its affiliate currently may be receiving such payments and to obtain further information regarding any such payments.

D. Sponsorship and Other Incentive Payments and Services

In addition to the Additional Payments described above, BlackRock and its affiliates may contribute to various other incentive arrangements to promote the sale of shares, including hosting proprietary and financially sponsoring Service Organizations’ training and educational seminars, conferences, meetings or events. BlackRock and its affiliates may also pay for the travel, meal, lodging and other expenses of Service Organizations and their salespersons or other personnel in connection with educational and sales promotional programs. This compensation is not included in, and is made in addition to, the Additional Payments described above. These payments may be made directly to the Service Organizations, or to a third party vendor, and may vary depending upon the nature of the event or the relationship and are subject to applicable laws and regulations, including the rules of applicable self-regulatory organizations, such as FINRA. BlackRock may pay Service Organizations additional types of incentive compensation in the future to the extent not prohibited by applicable laws or regulations.

Separately, BlackRock and its affiliates have developed proprietary tools, calculators and related interactive or digital content that is made available through the www.BlackRock.com website at no additional cost to Service Organizations. BlackRock configures these tools and calculators and localizes the content for Service Organizations as part of its customary digital marketing support and promotion of the Funds or other BlackRock funds, iShares exchange traded funds and other exchange traded products.

II-41

Table of Contents

E. Conflicts

Additional Payments made by BlackRock to a Service Organization or other incentive arrangements may be an important factor in the Service Organization’s willingness to support the sale of a Fund and/or particular share class through its distribution system or to perform services with respect to such Fund. Additional Payments and other incentive arrangements may also be important factors in the Service Organization’s willingness to recommend the BlackRock Fund complex in general.

BlackRock may be motivated to pay Additional Payments and other incentive compensation to promote the sale of Fund shares to customers of Service Organizations and the retention of those investments by such customers. To the extent Service Organizations sell more shares of a Fund or retain shares of a Fund in their customers’ accounts, BlackRock benefits from the incremental management and other fees paid by the Fund with respect to those assets.

Service Organizations may have financial incentives for recommending a particular Fund, share class or fund complex over another. Service Organizations may charge their customers additional fees in connection with the purchase or redemption of Fund shares or for account-related services which are in addition to the sales and other charges described in the Fund’s Prospectus and this SAI. Such charges may vary among Service Organizations but in all cases will be retained by the Service Organization and will not be remitted to a Fund or BlackRock.

Shareholders should consider whether such incentives exist when evaluating any recommendations from a Service Organization to purchase or sell shares of a Fund and when considering which share class is most appropriate. You should consult with your Service Organization, and review carefully any disclosure by the Service Organization, as to compensation received by it and for more information about the payments described above.

Redemption of Shares

Each Fund will normally redeem shares for cash upon receipt of a request in proper form, although each Fund retains the right to redeem some or all of its shares in-kind under unusual circumstances, in order to protect the interests of remaining shareholders, or to accommodate a request by a particular shareholder that does not adversely affect the interest of the remaining shareholders, by delivery of securities selected from the Fund’s assets at its discretion. In-kind payment means payment will be made in portfolio securities rather than cash. If this occurs, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities to cash. Each Fund has elected to be governed by Rule 18f-1 under the Investment Company Act so that the Fund is obligated to redeem its shares solely in cash up to the lesser of $250,000 or 1% of its net asset value during any 90-day period for any shareholder of the Fund. The redemption price is the net asset value per share next determined after the initial receipt of proper notice of redemption.

The value of the shareholder’s investment at the time of redemption may be more or less than his or her cost, depending on the market value of the securities held by the Fund at such time and income earned. In the case of Investor B Shares of Summit Cash Reserves, the redemption price will be reduced by any applicable CDSC.

If notice is received by the Fund’s transfer agent or Merrill Lynch, as applicable, prior to the applicable cut-off time on that day, the redemption will be effective on such day. If the notice is received after the applicable cut-off time, the redemption will be effective on the next business day and, unless otherwise provided in the Fund’s Prospectus, payment will be made on the second business day after receipt of the notice.

Redemption of Shares by All Funds except the BIF Funds, the BBIF Funds and the BlackRock Funds Portfolio

At various times, a Fund may be requested to redeem shares, in manual or automatic redemptions, with respect to which good payment has not yet been received by Merrill Lynch. A Fund may delay for up to 10 days the payment of redemption proceeds until good payment (that is, cash, Federal Funds or certified check drawn on a U.S. bank) has been collected for the purchase of Fund shares. In addition, each Fund reserves the right not to honor redemption checks or requests for Federal Funds redemptions where the shares to be redeemed have been purchased by check within 10 days prior to the date the redemption request is received by the Fund’s transfer agent.

The right to redeem shares may be suspended for more than seven days only (i) for any period during which trading on the NYSE is restricted as determined by the Commission or during which the NYSE is closed (other than customary weekend and holiday closings), (ii) for any period during which an emergency exists, as defined by the Commission, as a result of which disposal of portfolio securities or determination of the net asset value of the Fund is not reasonably practicable, or (iii) for such other periods as the Commission may by order permit for the protection of shareholders of the Fund.

II-42

Table of Contents

Methods of Redemption

All five methods set forth below apply to each Fund other than Retirement Reserves. Only the methods described under “Redemption by Check,” “Regular Redemption” and “Automatic Redemption” also apply to Retirement Reserves. In certain instances, the Fund’s transfer agent may require additional documents in connection with redemptions.

Redemption by Check. You may redeem shares by check in an amount not less than $500. At your request, the Fund’s transfer agent will provide you with checks drawn on the custody account. These checks can be made payable to the order of any person; however, these checks may not be used to purchase securities in transactions with Merrill Lynch. The payee of the check may cash or deposit it like any check drawn on a bank. When such a check is presented to the Fund’s transfer agent for payment, the Fund’s transfer agent will present the check to the Fund as authority to redeem a sufficient number of full and fractional shares in your account to cover the amount of the check. This enables you to continue earning daily dividends until the day prior to the day the check is cleared. Canceled checks will be returned to you by the Fund’s transfer agent upon request.

You will be subject to the transfer agent’s rules and regulations governing such checking accounts, including the right of the Fund’s transfer agent not to honor checks in amounts exceeding the value of your account at the time the check is presented for payment. A Fund or a Fund’s transfer agent may modify or terminate the check redemption privilege at any time on 30 days’ notice. In order to be eligible for the privilege, you should check the box under the caption “Check Redemption Privilege” in the Purchase Application. The Fund’s transfer agent will then send you checks. Retirement Reserves does not accept new applications for check writing privileges.

Federal Funds Redemption. If you maintain an account directly with the Fund’s transfer agent, you may also arrange to have redemption proceeds of $5,000 or more wired in Federal Funds to a pre-designated bank account. In order to be eligible for Federal Funds redemption, you must designate on your Purchase Application the domestic commercial bank and account number to receive the proceeds of your redemption and must have your signature on the Purchase Application guaranteed. The request for Federal Funds redemption may be made by telephone, wire or letter (no signature guarantee required) to the Fund’s transfer agent. If your request is received before the determination of net asset value of a Fund on any business day, the redemption proceeds will be wired to your pre-designated bank account on the next business day. You may request Federal Funds redemptions by calling the Fund’s transfer agent toll-free at 1-800-221-7210. Each Fund will employ reasonable procedures to confirm that telephone instructions are genuine to prevent any losses from fraudulent or unauthorized instructions. Among other things, redemption proceeds may only be wired into the bank account designated on the Purchase Application. You must independently verify this information at the time the redemption request is made. If you do not maintain an account directly with the Fund’s transfer agent, you should contact your financial adviser.

Repurchase Through Securities Dealers. Each Fund will repurchase shares through securities dealers. A Fund normally will accept orders to repurchase shares by wire or telephone from dealers for customers at the net asset value next computed after receipt of the order from the dealer, provided that the request is received from the dealer prior to the determination of net asset value of the Fund, on any business day. These repurchase arrangements are for your convenience and do not involve a charge by the Fund; however, dealers may impose a charge for transmitting the notice of repurchase to a Fund. Each Fund reserves the right to reject any order for repurchase through a securities dealer, but it may not reject properly submitted requests for redemption as described below. A Fund will promptly notify you of any rejection of a repurchase with respect to your shares. If you effect a repurchase through your securities dealer, payment will be made by the Fund’s transfer agent to the dealer.

Regular Redemption. If you hold shares with the Fund’s transfer agent you may redeem by writing to the Fund’s transfer agent, Financial Data Services, LLC, P.O. Box 40486, Jacksonville, Florida 32203-0486. Redemption requests that are sent by mail should be delivered to Financial Data Services, LLC, 4800 Deer Lake Drive East, Jacksonville, Florida 32246-6484. Redemption requests should not be sent to the Fund. A redemption request requires the signatures of all persons in whose name(s) the shares are registered, signed exactly as such name(s) appear on the transfer agent’s register. The signature(s) on the redemption request may require a guarantee by an “eligible guarantor institution” as defined in Rule 17Ad-15 under the Exchange Act, whose existence and validity may be verified by the Fund’s transfer agent through the use of industry publications. In the event a signature guarantee is required, notarized signatures are not sufficient. In general, signature guarantees are waived on redemptions of less than $50,000 as long as the following requirements are met: (i) the request contains the signature(s) of all persons in whose name(s) shares are recorded on the transfer agent’s register; (ii) the check is mailed to the stencil address of record on the transfer agent’s register and (iii) the stencil address has not changed within 30 days. Certain rules may apply regarding certain types of accounts, including, but not limited to, UGMA/UTMA accounts, Joint Tenancies with Rights of Survivorship, contra broker transactions, and institutional accounts. In

II-43

Table of Contents

certain instances, the Fund’s transfer agent may require additional documents such as, but not limited to, trust instruments, death certificates, appointments as executor or administrator, or certificates of corporate authority. Payments will be mailed within seven days of receipt by the Fund’s transfer agent of a proper redemption request.

You may also redeem shares held with the Fund’s transfer agent by calling 1-800-221-7210. You must be the shareholder of record and the request must be for an amount less than $50,000. Before telephone requests will be honored, signature approval from all shareholders of record on the account must be obtained. The shares being redeemed must have been held for at least 15 days. Telephone redemption requests will not be honored if: (i) the account holder is deceased, (ii) the proceeds are to be sent to someone other than the shareholder of record, (iii) funds are to be wired to the client’s bank account, (iv) a Systematic Withdrawal Plan is in effect, (v) the request is by an individual other than the account holder of record, (vi) the account is held by joint tenants who are divorced, (vii) the address on the account has changed within the last 30 days or (viii) to protect against fraud, if the caller is unable to provide the account number, the name and address registered on the account and the social security number registered on the account. The Funds or the Funds’ transfer agent may temporarily suspend telephone transactions at any time.

Shareholders of Retirement Reserves and participants in Custodial Plans that invest in U.S.A. Government Money may redeem shares by writing directly to Merrill Lynch. Shareholders of Retirement Reserves and participants in Custodial Plans that invest in U.S.A. Government Money should not send redemption requests to the Fund or to its transfer agent. If you inadvertently send the redemption request to the Fund or the Fund’s transfer agent, the request will be forwarded to Merrill Lynch. The notice must bear the signature of the person in whose name the Plan is maintained, signed exactly as his or her name appears on the Plan adoption agreement.

Automatic Redemption. Merrill Lynch has instituted an automatic redemption procedure, which applies to you if you maintain a securities account with Merrill Lynch. This procedure, which does not apply to margin accounts, may be used by Merrill Lynch to satisfy amounts you owe to Merrill Lynch or one of its affiliates as a result of account fees and expenses or as a result of purchases of securities or other transactions in your securities account. Under this procedure, unless you notify Merrill Lynch to the contrary, your Merrill Lynch securities account will be scanned each business day prior to the determination of net asset value of the Fund. After application of any cash balances in the account, a sufficient number of Fund shares may be redeemed at net asset value, as determined that day, to satisfy any amounts you owe to Merrill Lynch or one of its affiliates. Redemptions will be effected on the business day preceding the date you are obligated to make such payment, and Merrill Lynch or its affiliate will receive the redemption proceeds on the day following the redemption date. You will receive all dividends declared and reinvested through the date of redemption.

Unless otherwise requested, if you request transactions that settle on a “same-day” basis (such as Federal Funds wire redemptions, branch office checks, transfers to other Merrill Lynch accounts and certain securities transactions) the Fund shares necessary to effect such transactions will be deemed to have been transferred to Merrill Lynch prior to the Fund’s declaration of dividends on that day. In such instances, you will receive all dividends declared and reinvested through the date immediately preceding the date of redemption.

If your account held directly with the Fund’s transfer agent contains a fractional share balance, such fractional share balance will be automatically redeemed by a Fund. Because of the high cost of maintaining smaller accounts, a Fund may redeem shares in your account if the net asset value of your account is below $500. You will be notified that the value of your account is less than $500 before the Fund makes an involuntary redemption. You will then have 60 days to make an additional investment to bring the value of your account to at least $500 before the Fund takes any action. This involuntary redemption does not apply to retirement plans or Uniform Gifts or Transfers to Minors Act accounts.

U.S.A. Government Money has instituted an automatic redemption procedure for participants in the Custodial Plans who have elected to have cash balances in their accounts automatically invested in shares of the Fund. In the case of such participants, unless directed otherwise, Merrill Lynch will redeem a sufficient number of shares of the Fund to purchase other securities (such as common stocks) that the participant has selected for investment in his or her Custodial Plan account.

BIF Funds — Redemption of Shares by CMA Service Subscribers

BIF Funds — Automatic Redemptions. Redemptions will be effected automatically by Merrill Lynch to satisfy debit balances in the CMA service or other Merrill Lynch central asset account program, or the WCMA service created by securities transaction activity within the account or to satisfy debit balances created by card purchases, cash advances or checks. Each account will be scanned automatically for debits each business day prior to 12:00 noon,

After applying any free cash balances in the account to such debits, shares of the designated Fund will be redeemed at net asset value at the 12:00 noon pricing, and funds deposited pursuant to a bank deposit program will be withdrawn, to the extent necessary to satisfy any remaining debits in the account. Automatic redemptions or withdrawals will be made first from your Money Account. With respect to transactions that settle on a “same-day” basis (such as Federal funds wire redemptions, branch office checks, transfers to other Merrill Lynch accounts and certain securities transactions) the Fund shares necessary to effect such a transaction will be deemed to have been transferred to Merrill Lynch prior to the Fund’s declaration of dividends on that day. In such instances, you will receive all dividends declared through the date immediately preceding the date of redemption. Margin loans through the Margin Lending Program will be used to satisfy debits remaining after the liquidation of all funds invested in or deposited through the Money Account CMA service (or other Merrill Lynch central asset account). Shares of the BIF Funds may not be purchased, nor may deposits be made pursuant to a bank deposit program until all debits and margin loans in the account are satisfied.

Shares of each BIF Fund also may be automatically redeemed to satisfy debits or make investments in connection with special features offered to CMA service or other Merrill Lynch central asset account program subscribers. For more information regarding these features, you should consult the relevant program disclosure.

BIF Funds — Manual Redemptions. If you are a CMA service or other Merrill Lynch central asset account subscriber or if you hold shares of a BIF Fund in a Merrill Lynch securities account, you may redeem shares of a BIF Fund directly by contacting Merrill Lynch. Cash proceeds from the manual redemption of Fund shares ordinarily will be mailed to you at your address of record or, on request, mailed or wired (if $10,000 or more) to your bank account. Redemption requests should not be sent to a Fund or a Fund’s transfer agent. If you inadvertently send the request to a Fund or a Fund’s transfer agent, the request will be forwarded to Merrill Lynch. The signature requirements of the redemption request are described above under “Redemption of Shares — Redemptions of Shares by All Funds except the BIF Funds and the BBIF Funds — Regular Redemption.” CMA service (or other Merrill Lynch central asset account) subscribers desiring to effect manual redemptions should contact their financial advisers. All redemptions of Fund shares will be confirmed to service subscribers in the monthly transaction statement.

BBIF Funds — Redemption of Shares by WCMA Service Subscribers

BBIF Funds — Automatic Redemptions. Redemptions will be effected automatically by Merrill Lynch to satisfy debit balances in a WCMA service or other business account program account created by securities transactions therein or to satisfy debit balances created by credit card purchases, cash advances (which may be obtained through participating banks and automated teller machines) or checks written against the credit card account or electronic fund transfers or other debits. Each WCMA service or other business account program account will be scanned automatically for debits each business day prior to 12 noon, Eastern time. After application of any free cash balances in the account to such debits, shares of the designated BBIF Fund will be redeemed at net asset value at the 12 noon pricing, and funds deposited pursuant to the Insured Savings Account will be withdrawn, to the extent necessary to satisfy any remaining debits in the account. Automatic redemptions or withdrawals will be made first from the subscriber’s Primary Money Account and then, to the extent necessary, from accounts not designated as the Primary Money Account. With respect to transactions that settle on a “same-day” basis (such as Federal funds wire redemptions, branch office checks, transfers to other Merrill Lynch accounts and certain securities transactions) the Fund shares necessary to effect such transactions will be deemed to have been transferred to Merrill Lynch prior to the Fund’s declaration of dividends on that day. In such instances, shareholders will receive all dividends declared through the date immediately preceding the date of redemption. Unless otherwise requested by the subscriber, redemptions or withdrawals from non-Primary Money Accounts will be made in the order the non-Primary Money Accounts were established; thus, redemptions or withdrawals will first be made from the non-Primary Money Account that the subscriber first established. Margin loans through the Margin Lending Program service will be used to satisfy debits remaining after the liquidation of all funds invested in or deposited through non-Primary Money Accounts, and shares of the BBIF Funds may not be purchased, nor may deposits be made pursuant to the Insured Savings Account, until all debits and margin loans in the account are satisfied.

Shares of the BBIF Funds also may be automatically redeemed to satisfy debits or make investments in connection with special features offered to service subscribers. The redemption of shares of the BBIF Funds also may be modified for investors that participate in certain fee-based programs. For more information regarding these features, a WCMA service subscriber should consult the Business Investor Account ^SM (BIA ^SM ) Financial Service and Working Capital Management Account ^® (WCMA ^® ) Financial Service Account Agreement Program Description Booklet.

From time to time, Merrill Lynch also may offer the BBIF Funds to subscribers in certain other programs sponsored by Merrill Lynch. Some or all of the features of the WCMA service may not be available in such programs and program participation and other fees may be higher. More information on the services and fees associated with such other programs is set forth in the Program Description Booklet that is furnished in connection with such other programs, which may be obtained by contacting a Merrill Lynch financial adviser.

BBIF Funds — Manual Redemptions. Merrill Lynch will satisfy requests for cash by wiring cash to the shareholder’s bank account or arranging for the shareholder’s Merrill Lynch financial adviser to provide the shareholder with a check. Redemption requests should not be sent to the BBIF Fund or its transfer agent. If inadvertently sent to the BBIF Fund or the Fund’s transfer agent, redemption requests will be forwarded to Merrill Lynch. Any required shareholder signature(s) must be guaranteed by an “eligible guarantor institution” as such is defined in Rule 17Ad-15 under the Exchange Act, the existence and validity of which may be verified by the Fund’s transfer agent through the use of industry publications. Notarized signatures are not sufficient. In certain instances, additional documents such as, but not limited to, trust instruments, death certificates, appointments as executor or administrator, or certificates of corporate authority may be required. Subscribers in the WCMA service or other business account program desiring to effect manual redemptions should contact their Merrill Lynch financial adviser.

All redemptions of BBIF Fund shares will be confirmed to WCMA service subscribers (rounded to the nearest share) in the monthly transaction statement.

BIF Funds — Redemption of Shares by Non-Service Subscribers

Shareholders who are not CMA service or other Merrill Lynch central asset account subscribers may redeem shares of a BIF Fund held in a Merrill Lynch securities account directly as described above under “Redemption of Shares — Redemption of Shares by Service Subscribers — Manual Redemptions.”

Shareholders maintaining an account directly with the Fund’s transfer agent, who are not CMA service (or other Merrill Lynch central asset account) subscribers, may redeem shares of a BIF Fund by submitting a written notice by mail directly to the Fund’s transfer agent, Financial Data Services, LLC, P.O. Box 40486, Jacksonville, Florida 32203-0486. Redemption requests that are sent by hand should be delivered to Financial Data Services, LLC, 4800 Deer Lake Drive East, Jacksonville, Florida 32246-6484. Cash proceeds from the manual redemption of Fund shares will be mailed to the shareholder at his or her address of record. Redemption requests should not be sent to a Fund or Merrill Lynch. If inadvertently sent to a Fund or Merrill Lynch such redemption requests will be forwarded to the Fund’s transfer agent. The notice requires the signatures of all persons in whose names the shares are registered, signed exactly as their names appear on their monthly statement. The signature(s) on the redemption request must be guaranteed by an “eligible guarantor institution” as such is defined in Rule 17Ad-15 under the Exchange Act, the existence and validity of which may be verified by the Fund’s transfer agent through the use of industry publications. Notarized signatures are not sufficient. In certain instances, additional documents such as, but not limited to, trust instruments, death certificates, appointments as executor or administrator, or certificates of corporate authority may be required.

The right to receive payment with respect to any redemption of Fund shares may be suspended by each Fund for a period of up to seven days. Suspensions of more than seven days may not be made except (1) for any period (A) during which the NYSE is closed other than customary weekend and holiday closings or (B) during which trading on the NYSE is restricted; (2) for any period during which an emergency exists as a result of which (A) disposal by the Fund of securities owned by it is not reasonably practicable or (B) it is not reasonably practicable for the Fund fairly to determine the value of its net assets; or (3) for such other periods as the Commission may by order permit for the protection of shareholders of the Fund. The Commission shall by rules and regulations determine the conditions under which (i) trading shall be deemed to be restricted and (ii) an emergency shall be deemed to exist within the meaning of clause (2) above.

The value of a Fund’s shares at the time of redemption may be more or less than the shareholder’s cost, depending on the market value of the securities held by the Fund at such time.

From time to time, Merrill Lynch also may offer the Funds to participants in certain other programs sponsored by Merrill Lynch. Some or all of the features of the CMA service may not be available in such programs and program participation and other fees may be higher. More information on the services and fees associated with such programs, is set forth in the relevant program disclosures, which may be obtained by contacting a Merrill Lynch financial adviser.

BlackRock Funds Portfolio — Redemption of Shares

Redemptions may be made in the manner and amounts described in the BlackRock Funds Portfolio’s Prospectuses. Signatures, when required, must conform exactly to the account registration. If (i) the proceeds of the redemption would exceed $250,000 for a redemption by wire or ACH, or $100,000 for a redemption by check, (ii) the Fund does not have verified banking information on file, (iii) the proceeds are not to be paid to the record owner at the record address, or (iv) the shareholder is a corporation, partnership, trust or fiduciary, signature(s) must be guaranteed by any eligible guarantor institution.

Generally, a properly signed written request with any required signature guarantee is all that is required for a redemption. In some cases, however, other documents may be necessary. Additional documentary evidence of authority is required by BNY Mellon in the event redemption is requested by a corporation, partnership, trust, fiduciary, executor or administrator. See “Signature Guarantee” below.

Note on Low Balance Accounts. Because of the high cost of maintaining smaller shareholder accounts, BlackRock has set a minimum balance of $500 in each Fund position you hold within your account (“Fund Minimum”), and may redeem the shares in your account if the net asset value of those shares in your account falls below $500 for any reason, including market fluctuation.

Service Shares

Redemption of Shares. The BlackRock Funds Portfolio may redeem Service Shares if the account balance drops below the required minimum initial investment as the result of redemption requests and the shareholder does not increase the balance to at least the required minimum initial investment upon thirty days’ written notice. If a customer has agreed with an institution to maintain a minimum balance in his or her account with the institution, and the balance in the account falls below that minimum, the customer may be obligated to redeem all or part of his or her shares in the Fund to the extent necessary to maintain the minimum balance required.

The following is applicable only to persons who were shareholders of an investment portfolio of Compass Capital Group of Funds at the time of the Trust’s combination with The PNC Fund in 1996:

Persons who were shareholders of an investment portfolio of Compass Capital Group of Funds at the time of the portfolio’s combination with The PNC Fund may also purchase and redeem Service Shares of the same Fund and for the same account in which they held shares on that date through the procedures described in this section.

Payment of Redemption Proceeds. The Fund may suspend the right of redemption or postpone the date of payment upon redemption for such periods as are permitted under the Investment Company Act, and may redeem shares involuntarily or make payment for redemption in securities or other property when determined appropriate in light of the Fund’s responsibilities under the Investment Company Act.

The Fund reserves the right, if conditions exist which make cash payments undesirable, to honor any request for redemption or repurchase of the Fund’s shares by making payment in whole or in part in securities chosen by the Fund and valued in the same way as they would be valued for purposes of computing the Fund’s net asset value. If payment is made in securities, a shareholder may incur transaction costs in converting these securities into cash. The Fund has elected, however, to be governed by Rule 18f-1 under the Investment Company Act so that the Fund is obligated to redeem its shares solely in cash up to the lesser of $250,000 or 1% of its net asset value during any 90-day period for any one shareholder of the Fund.

The Board of the BlackRock Funds Portfolio will be permitted to impose a liquidity fee on redemptions from the Fund (up to 2%) or temporarily restrict redemptions from the Fund for up to 10 business days. Please see the Fund’s Prospectus for additional information about liquidity fees and redemption gates.

Under the Investment Company Act, the Fund may suspend the right to redemption or postpone the date of payment upon redemption for any period during which the NYSE is closed (other than customary weekend and holiday closings), or during which trading on the NYSE is restricted, or during which (as determined by the SEC by rule or regulation) an emergency exists as a result of which disposal or valuation or portfolio securities is not reasonably

II-47

Table of Contents

practicable, or for such other periods as the SEC may permit. (A Portfolio may also suspend or postpone the recordation of the transfer of its shares upon the occurrence of any of the foregoing conditions.)

The Fund may redeem shares involuntarily to reimburse the Fund for any loss sustained by reason of the failure of a shareholder to make full payment for shares purchased by the shareholder or to collect any charge relating to a transaction effected for the benefit of a shareholder. The Fund reserves the express right to redeem shares of the Fund involuntarily at any time if the Board of Trustees determines, in its sole discretion, that failure to do so may have adverse consequences to the holders of shares in the Fund. Upon such redemption the holders of shares so redeemed shall have no further right with respect thereto other than to receive payment of the redemption price.

The BlackRock Funds Portfolio reserves the right to redeem shares in any account that it cannot confirm to its satisfaction is beneficially owned by a natural person, after providing at least 60 days’ advance notice.

Signature Guarantee. A signature guarantee is designed to protect the shareholders and the Fund against fraudulent transactions by unauthorized persons. A signature guarantee may be obtained from a domestic bank or trust company, recognized broker, dealer, clearing agency, savings association who are participants in a medallion program by the Securities Transfer Association, credit unions, national securities exchanges and registered securities associations. The three recognized medallion programs are Securities Transfer Agent Medallion Program (STAMP), Stock Exchanges Medallion Program (SEMP) and New York Stock Exchange, Inc. Medallion Signature Program (MSP). Signature Guarantees which are not a part of these programs will not be accepted. Please note that a notary public stamp or seal is not acceptable.

Shareholder Services

Shareholder Services for All Funds other than BIF Funds, BBIF Funds, Retirement Reserves and BlackRock Funds Portfolio

Each Fund offers one or more of the shareholder services described below that are designed to facilitate investment in its shares. Certain of these services are available only to U.S. investors. You can obtain more information about these services from each Fund by calling the telephone number on the cover page of the Part I of this SAI, or from the Distributor.

Investment Account

If your account is maintained at the Fund’s transfer agent (an “Investment Account”) you will receive a monthly report showing the activity in your account for the month. You may make additions to your Investment Account at any time by purchasing shares at the applicable public offering price either through your securities dealer, by wire or by mail directly to the Fund’s transfer agent. You may ascertain the number of shares in your Investment Account by calling the Fund’s transfer agent toll-free at 1-800-221-7210. The Fund’s transfer agent will furnish this information only after you have specified the name, address, account number and social security number of the registered owner or owners. You may also maintain an account through Merrill Lynch. If you transfer shares out of a Merrill Lynch brokerage account, an Investment Account in your name may be opened at the Fund’s transfer agent. If you are considering transferring a tax-deferred retirement account such as an IRA from Merrill Lynch to another brokerage firm or financial institution you should be aware that if the firm to which the retirement account is to be transferred will not take delivery of shares of a Fund, you must either redeem the shares so that the cash proceeds can be transferred to the account at the new firm, or you must continue to maintain a retirement account at Merrill Lynch for those shares.

In the interest of economy and convenience and because of the operating procedures of each Fund, share certificates will not be issued physically. Shares are maintained by each Fund on its register maintained by the Fund’s transfer agent and the holders thereof will have the same rights and ownership with respect to such shares as if certificates had been issued.

Fee-Based Programs

Fund shares may be held in certain fee-based programs offered by the Manager or its affiliates, including pricing alternatives for securities transactions (each referred to in this paragraph as a “Program”). These Programs generally prohibit such shares from being transferred to another account at Merrill Lynch, to another broker-dealer or to the Fund’s transfer agent. Except in limited circumstances, such shares must be redeemed and new shares purchased in order for the investment not to be subject to Program fees. Additional information regarding a specific Program

II-48

Table of Contents

(including charges and limitations on transferability applicable to shares that may be held in such Program) is available in such Program’s client agreement and from the Fund’s transfer agent at 1-800-221-7210.

Automatic Investment Plans

If you maintain an account directly with the Fund’s transfer agent, each Fund offers an Automatic Investment Plan whereby the Fund’s transfer agent is authorized through preauthorized checks of $50 or more to charge your regular bank account on a regular basis to provide systematic additions to the Investment Account. Your Automatic Investment Plan may be terminated at any time without charge or penalty by you, the Fund, the Fund’s transfer agent or the Distributor. If you do not maintain an account directly with the Fund’s transfer agent, you should contact your financial professional.

Accrued Monthly Payout Plan

The dividends paid by each Fund are generally reinvested automatically in additional shares. If you maintain an account at the Fund’s transfer agent and desire cash payments, you may enroll in the Accrued Monthly Payout Plan. Under this plan, shares equal in number to shares credited through the automatic reinvestment of dividends during each month are redeemed at net asset value on the last Friday of such month in order to meet the monthly distribution (provided that, in the event that a payment on an account maintained with the Fund’s transfer agent would be $10.00 or less, the payment will be automatically reinvested in additional shares). You may open an Accrued Monthly Payout Plan by completing the appropriate portion of the Purchase Application. Your Accrued Monthly Payout Plan may be terminated at any time without charge or penalty by you, a Fund, the Fund’s transfer agent or the Distributor. If you do not maintain an account directly with the Fund’s transfer agent, you should contact your financial professional.

Systematic Withdrawal Plans

If you maintain an account with the Fund’s transfer agent, you may elect to receive systematic withdrawals from your Investment Account by check or through automatic payment by direct deposit to your bank account on either a monthly or quarterly basis as provided below. Quarterly withdrawals are available if you have acquired shares of a Fund that have a value, based on cost or the current offering price, of $5,000 or more, and monthly withdrawals are available if your shares have a value of $10,000 or more.

At the time of each withdrawal payment, sufficient shares are redeemed from your Investment Account to provide the withdrawal payment specified by you, which may be a dollar amount or a percentage of the value of your shares. Redemptions will be made at net asset value as determined as of the close of business on the NYSE on the 24th day of each month or the 24th day of the last month of each quarter, whichever is applicable. If the NYSE is not open for business on such date, the shares will be redeemed at the net asset value determined as of the close of business on the NYSE on the following business day. The check for the withdrawal payment will be mailed or the direct deposit will be made, on the next business day following redemption. When you make systematic withdrawals, dividends and distributions on all shares in the Investment Account are reinvested automatically in Fund shares. Your systematic withdrawal plan may be terminated at any time, without charge or penalty, by you, a Fund, the Fund’s transfer agent or the Distributor. You may not elect to make systematic withdrawals while you are enrolled in the Accrued Monthly Payout Plan. A Fund is not responsible for any failure of delivery to the shareholder’s address of record and no interest will accrue on amounts represented by uncashed distribution or redemption checks.

Withdrawal payments should not be considered as dividends. Withdrawals generally are treated as sales of shares and may result in taxable gain or loss. If periodic withdrawals continuously exceed reinvested dividends, the original investment will be reduced correspondingly. You are cautioned not to designate withdrawal programs that result in an undue reduction of principal. There are no minimums on amounts that may be systematically withdrawn. Periodic investments may not be made into an Investment Account in which a shareholder has elected to make systematic withdrawals.

If your account is not maintained directly with the Fund’s transfer agent, you should contact your financial professional. If your account is currently maintained at a branch office, redemptions via the Systematic Withdrawal Plan will be credited directly to your Investment Account. If you wish to receive a redemption by check, you should contact your financial professional.

Retirement and Education Accounts

Individual retirement accounts, Roth IRAs and other retirement plan accounts (together, “retirement accounts”) are available from your financial intermediary. Under these plans, investments may be made in a Fund and certain other mutual funds sponsored by the Manager or its affiliates as well as in other securities. There may be fees associated with investing through these accounts. Information with respect to these accounts is available on request from your financial intermediary.

Dividends received in each of the accounts referred to above are exempt from Federal taxation until distributed from the accounts and, in the case of Roth IRAs and education accounts, may be exempt from taxation when distributed as well. Investors considering participation in any retirement or education account should review specific tax laws relating to the account and should consult their attorneys or tax advisors with respect to the establishment and maintenance of any such account.

Determination of Net Asset Value

Each Fund seeks to maintain a net asset value of $1.00 per share for purposes of purchase and redemptions and values its portfolio securities on the basis of the amortized cost method of valuation.

Under this method portfolio securities are valued at cost when purchased and thereafter, a constant proportionate accretion of any discount or amortization of premium is recorded until the maturity of the security. The effect of changes in the market value of a security as a result of fluctuating interest rates is not taken into account.

As indicated, the amortized cost method of valuation may result in the value of a security being higher or lower than its market price, the price a Fund would receive if the security were sold prior to maturity. Each Fund’s Board has established procedures for the purpose of maintaining a constant net asset value of $1.00 per share for each Fund; however, there can be no assurance that a constant net asset value will be maintained for any Fund. Such procedures include a review of the extent of any deviation of net asset value per share, based on available market quotations, from the $1.00 amortized cost per share.

Should that deviation exceed ½ of 1% for a Fund, the Fund’s Board will promptly consider whether any action should be initiated to eliminate or reduce material dilution or other adverse impact to shareholders. Such action may include redeeming shares in kind, selling portfolio securities prior to maturity, reducing or withholding dividends, shortening the average portfolio maturity, and utilizing a net asset value per share as determined by using available market quotations.

Each Fund will maintain a dollar-weighted average portfolio maturity of 60 days or less, a dollar-weighted average life of 120 days or less, will not purchase any instrument with a deemed maturity under Rule 2a-7 of the Investment Company Act greater than 397 days, and will limit portfolio investments, including repurchase agreements, to those instruments that the adviser or sub-adviser determines present minimal credit risks pursuant to guidelines adopted by a Fund’s Board.

Yield Information

Each Fund computes its annualized yield in accordance with regulations adopted by the Commission by determining the net changes in value, exclusive of capital changes and income other than investment income, for a seven-day base period for a hypothetical pre-existing account having a balance of one share at the beginning of the base period, subtracting a hypothetical shareholder account charge, and dividing the difference by the value of the account at the beginning of the base period to obtain the base period return, and then multiplying the result by 365 and then dividing by seven. This yield calculation does not take into consideration any realized or unrealized gains or losses on portfolio securities. The Commission also permits the calculation of a standardized effective or compounded yield. This is computed by compounding the unannualized base period return, which is done by adding one to the base period return, raising the sum to a power equal to 365 divided by seven, and subtracting one from the result. This compounded yield calculation also excludes realized and unrealized gains or losses on portfolio securities.

The yield on each Fund’s shares normally will fluctuate on a daily basis. Therefore, the yield for any given past period is not an indication or representation by a Fund of future yields or rates of return on its shares. The yield is affected by such factors as changes in interest rates on a Fund’s portfolio securities, average portfolio maturity, the types and quality of portfolio securities held and operating expenses. The yield on Fund shares for various reasons may not be comparable to the yield on bank deposits, shares of other money market funds or other investments.

II-50

Table of Contents

See Part I, Section VI “Yield Information” of each Fund’s SAI for recent seven-day yield information relating to your Fund.

On occasion, each Fund may compare its yield to (1) an industry average compiled by Donoghue’s Money Fund Report, a widely recognized independent publication that monitors the performance of money market mutual funds, (2) the average yield reported by the Bank Rate Monitor National Index ^TM for money market deposit accounts offered by the 100 leading banks and thrift institutions in the ten largest standard metropolitan statistical areas, (3) yield data published by industry publications, including Lipper Inc., Morningstar, Inc., Money Magazine, U.S. News & World Report, BusinessWeek, CDA Investment Technology, Inc., Forbes Magazine and Fortune Magazine , (4) the yield on an investment in 90-day Treasury bills on a rolling basis, assuming quarterly compounding, or (5) historical yield data relating to other central asset accounts similar to the CMA service, in the case of the BIF Funds. As with yield quotations, yield comparisons should not be considered indicative of a Fund’s yield or relative performance for any future period.

A Fund may provide information designed to help investors understand how the Fund is seeking to achieve its investment objective. This may include information about past, current or possible economic, market, political, or other conditions, descriptive information on general principles of investing such as asset allocation, diversification and risk tolerance; a discussion of a Fund’s portfolio composition, investment philosophy, strategy or investment techniques; comparisons of a Fund’s performance or portfolio composition to that of other funds or types of investments, to indices relevant to the comparison being made, or to a hypothetical or model portfolio. Each Fund may also quote various measures of volatility and benchmark correlation in advertising and other materials, and may compare these measures to those of other funds or types of investments.

Portfolio Transactions

Subject to policies established by the Board of each Fund, the Manager is primarily responsible for the execution of a Fund’s portfolio transactions. The Manager does not execute transactions through any particular broker or dealer, but seeks to obtain the best net results for the Fund, taking into account such factors as price (including the applicable dealer spread), size of order, difficulty of execution, operational facilities of the firm and the firm’s risk and skill in positioning blocks of securities. While the Manager generally seeks reasonable trade execution costs, a Fund does not necessarily pay the lowest spread or commission available. Each Fund’s policy of investing in securities with short maturities will result in high portfolio turnover.

Subject to obtaining the best net results, dealers who provide supplemental investment research (such as economic data and market forecasts) to the Manager may receive orders for transactions of the Fund. Information received will be in addition to and not in lieu of the services required to be performed by the Manager under each Management Agreement and the expenses of the Manager will not necessarily be reduced as a result of the receipt of such supplemental information.

The portfolio securities in which each Fund invests are traded primarily in the OTC market. Bonds and debentures usually are traded OTC, but may be traded on an exchange. Where possible, a Fund will deal directly with the dealers who make a market in the securities involved except in those circumstances where better prices and execution are available elsewhere. Such dealers usually are acting as principals for their own accounts. On occasion, securities may be purchased directly from the issuer. Money market securities are generally traded on a net basis and do not normally involve either brokerage commissions or transfer taxes. The cost of executing portfolio securities transactions of a Fund primarily will consist of dealer spreads. Under the Investment Company Act, persons affiliated with a Fund and persons who are affiliated with such affiliated persons are prohibited from dealing with the Fund as principals in the purchase and sale of securities unless an exemptive order allowing such transactions is obtained from the Commission. Since transactions in the OTC market usually involve transactions with the dealers acting as principals for their own accounts, the Funds will not deal with affiliated persons in connection with such transactions, except pursuant to an applicable exemptive order or as otherwise permitted by applicable law. However, an affiliated person of a Fund may serve as its broker in OTC transactions conducted on an agency basis.

The Manager does not consider sales of shares of the mutual funds it advises as a factor in the selection of brokers or dealers to execute portfolio transactions for a Fund; however, whether or not a particular broker or dealer sells shares of the mutual funds advised by the Manager neither qualifies nor disqualifies such broker or dealer to execute transactions for those mutual funds.

OTC issues, including most fixed income securities such as corporate debt and U.S. Government securities, are normally traded on a “net” basis without a stated commission, through dealers acting for their own account and not as brokers. The Funds will primarily engage in transactions with these dealers or deal directly with the issuer unless a

II-51

Table of Contents

better price or execution could be obtained by using a broker. Prices paid to a dealer with respect to both non-U.S. and domestic securities will generally include a “spread,” which is the difference between the prices at which the dealer is willing to purchase and sell the specific security at the time, and includes the dealer’s normal profit.

Purchases of money market instruments by a Fund are made from dealers, underwriters and issuers. The Funds do not currently expect to incur any brokerage commission expense on such transactions because money market instruments are generally traded on a “net” basis with dealers acting as principal for their own accounts without a stated commission. The price of the security, however, usually includes a profit to the dealer. Each money market Fund (each a “Money Market Portfolio”) intends to purchase only securities with remaining maturities of 13 months or less as determined in accordance with the rules of the SEC. As a result, the portfolio turnover rates of a Money Market Portfolio will be relatively high. However, because brokerage commissions will not normally be paid with respect to investments made by a Money Market Portfolio, the turnover rates should not adversely affect the Fund’s net asset values or net income.

Securities purchased in underwritten offerings include a fixed amount of compensation to the underwriter, generally referred to as the underwriter’s concession or discount. When securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid.

The Manager may seek to obtain an undertaking from issuers of commercial paper or dealers selling commercial paper to consider the repurchase of such securities from a Fund prior to maturity at their original cost plus interest (sometimes adjusted to reflect the actual maturity of the securities), if it believes that a Fund’s anticipated need for liquidity makes such action desirable. Any such repurchase prior to maturity reduces the possibility that a Fund would incur a capital loss in liquidating commercial paper, especially if interest rates have risen since acquisition of such commercial paper.

Investment decisions for each Fund and for other investment accounts managed by the Manager are made independently of each other in light of differing conditions. BlackRock allocates investments among client accounts in a fair and equitable manner. A variety of factors will be considered in making such allocations. These factors include: (i) investment objectives or strategies for particular accounts, including sector, industry, country or region and capitalization weightings, (ii) tax considerations of an account, (iii) risk or investment concentration parameters for an account, (iv) supply or demand for a security at a given price level, (v) size of available investment, (vi) cash availability and liquidity requirements for accounts, (vii) regulatory restrictions, (viii) minimum investment size of an account, (ix) relative size of account, and (x) such other factors as may be approved by BlackRock’s general counsel. Moreover, investments may not be allocated to one client account over another based on any of the following considerations: (i) to favor one client account at the expense of another, (ii) to generate higher fees paid by one client account over another or to produce greater performance compensation to BlackRock, (iii) to develop or enhance a relationship with a client or prospective client, (iv) to compensate a client for past services or benefits rendered to BlackRock or to induce future services or benefits to be rendered to BlackRock, or (v) to manage or equalize investment performance among different client accounts.

Because of different objectives or other factors, a particular security may be bought for one or more funds or clients advised by BlackRock or its affiliates (collectively, “clients”) when one or more clients of BlackRock or its affiliates are selling the same security. If purchases or sales of securities arise for consideration at or about the same time that would involve a Fund or other clients or funds for which BlackRock or an affiliate acts as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all. To the extent that transactions on behalf of more than one client of BlackRock or its affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price.

See Part I, Section VIII “Portfolio Transactions” of each Fund’s SAI for information relating to portfolio transactions engaged in by your Fund for its three most recently completed fiscal years or other relevant periods.

The Board of each Fund has considered the possibility of seeking to recapture for the benefit of the Fund expenses of possible portfolio transactions, such as dealer spreads and underwriting commissions, by conducting portfolio transactions through affiliated entities. After considering all factors deemed relevant, the Board of each Fund made a determination not to seek such recapture. The Board of each Fund will reconsider this matter from time to time.

Each Fund has received an exemptive order from the Commission permitting it to lend portfolio securities to its affiliates. Pursuant to that order, each Fund may retain an affiliated entity of the Manager (the “lending agent”) as the securities lending agent for a fee, including a fee based on a share of the returns on investment of cash collateral. The lending agent may, on behalf of a Fund, invest cash collateral received by the Fund for such loans,

II-52

Table of Contents

among other things, in a private investment company managed by the lending agent or in registered money market funds advised by the Manager or its affiliates. See Part I, Section VIII “Portfolio Transactions” of each Fund’s SAI for the securities lending agent fees, if any, paid by your Fund to the lending agent for the periods indicated.

Because of different objectives or other factors, a particular security may be bought for one or more funds or clients advised by the Manager or its affiliates (collectively, “clients”) when one or more clients of the Manager or its affiliates are selling the same security. If purchases or sales of securities arise for consideration at or about the same time that would involve a Fund or other clients or funds for which the Manager or an affiliate acts as investment manager, transactions in such securities will be made, insofar as feasible, for the respective funds and clients in a manner deemed equitable to all. To the extent that transactions on behalf of more than one client of the Manager or its affiliates during the same period may increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price.

Dividends and Taxes

Dividends

Each Fund declares dividends daily. Except as otherwise provided in a Fund’s Prospectus, dividends of each Fund are reinvested monthly in additional shares of that Fund at net asset value. Except as otherwise provided in a Fund’s Prospectus, shares purchased will begin accruing dividends on the day following the date of purchase. Dividends that are declared but unpaid will remain in the gross assets of each Fund and will therefore continue to earn income for the Fund’s shareholders. Shareholders will receive monthly statements as to such reinvestments. For shareholders of the BIF Funds and the BBIF Funds, with respect to certain transactions that settle on a “same day” basis (such as Federal Funds wire redemptions, branch office checks, transfers to other Merrill Lynch accounts and certain securities transactions), the Fund shares necessary to effect such transactions will be deemed to have been transferred to Merrill Lynch prior to the Funds’ declaration of dividends on that day.

Net income (from the time of the immediately preceding determination thereof) consists of (i) interest accrued and/or discount earned (including both original issue and market discount), (ii) less amortization of premiums and the estimated expenses of a Fund applicable to that dividend period. Net realized capital gains (including net short-term capital gain), if any, will be distributed by the Funds at least annually.

Retirement Accounts. Investment in certain Funds is offered to participants in retirement accounts for which Merrill Lynch acts as custodian, participants in Merrill Lynch Basic Plans and RSAs and certain independent qualified plans. Accordingly, the general description of the tax treatment of RICs and their shareholders set forth below is qualified for retirement accountholders with respect to the special tax treatment afforded such accounts under the Code. Under the Code, neither ordinary income dividends nor capital gain dividends represent current income to retirement accountholders.

Generally, distributions from a retirement account (other than certain distributions from a Roth IRA) will be taxable as ordinary income at the rate applicable to the participant at the time of the distribution. For most retirement accounts, such distributions would include (i) any pre-tax contributions to the retirement account (including pre-tax contributions that have been rolled over from another IRA or qualified retirement plan), and (ii) earnings (whether such earnings are classified as ordinary income or as capital gains). In addition to Federal income tax, participants may be subject to the imposition of a 10% (or, in the case of certain SRA distributions, 25%) additional tax on any amount withdrawn from a retirement account prior to the participant’s attainment of age 59½ unless one of the exceptions listed below applies.

Depending on the type of retirement plan, the exceptions to the early withdrawal penalty may include: 1) distributions after the death of the shareholder; 2) distributions attributable to disability; 3) distributions used to pay certain medical expenses; 4) distributions that are part of a scheduled series of substantially equal periodic payments for the life (or life expectancy) of the shareholder or the joint lives (or joint life and last survivor expectancy) of the shareholder and the shareholder’s beneficiary; 5) withdrawals for medical insurance if the shareholder has received unemployment compensation for 12 weeks and the distribution is made in the year such unemployment compensation is received or the following year; 6) distributions to pay qualified higher education expenses of the shareholder or certain family members of the shareholder; and 7) distributions used to buy a first home (subject to a $10,000 lifetime limit).

For Roth IRA participants, distributions, including accumulated earnings on contributions, will not be includable in income if such distribution is made five or more years after the first tax year of contribution and the account holder either is age 59½ or older, has become disabled, is purchasing a first home (subject to the $10,000 lifetime limit) or

II-53

Table of Contents

has died. As with other retirement accounts, a 10% excise tax applies to amounts withdrawn from the Roth IRA prior to reaching age 59½ unless one of the exceptions applies. Such a withdrawal would also be included in income to the extent of earnings on contributions, with distributions treated as made first from contributions and then from earnings.

Under certain limited circumstances (for example, if an individual for whose benefit a retirement account is established engages in any transaction prohibited under Section 4975 of the Code with respect to such account), a retirement account could cease to qualify for the special treatment afforded certain retirement accounts under the Code as of the first day of the taxable year in which the transaction that caused the disqualification occurred. If a retirement account through which a shareholder holds Fund shares becomes ineligible for special tax treatment, the shareholder will be treated as having received a distribution on the first day of such taxable year from the retirement account in an amount equal to the fair market value of all assets in the account. Thus, a shareholder would be taxed currently on the amount of any pre-tax contributions and previously untaxed dividends held within the account, and would be taxed on the ordinary income and capital gain dividends paid by a Fund subsequent to the disqualification event, whether such dividends were received in cash or reinvested in additional shares. These ordinary income and capital gain dividends also might be subject to state and local taxes. In the event of retirement account disqualification, shareholders also could be subject to the early withdrawal excise tax described above. Additionally, retirement account disqualification may subject a nonresident alien shareholder to a 30% United States withholding tax on ordinary income dividends paid by a Fund unless a reduced rate of withholding is provided under applicable treaty law or such dividends are designated as interest-related dividends or short-term capital gain dividends, as described in “Dividends and Taxes — Taxes — General Treatment of Fund Shareholders.”

In certain circumstances, account holders also may be able to make nondeductible contributions to their retirement accounts. As described above, ordinary income dividends and capital gain dividends received with respect to such contributions will not be taxed currently. Unlike the Roth IRA, described above, earnings with respect to these amounts will be taxed when distributed.

Qualified Tuition Program and ESAs. Investment in Retirement Reserves is also offered to participants in Qualified Tuition Program accounts and ESAs (together, “education accounts”). The general description of the tax treatment of RICs and their shareholders as set forth below is qualified for education accountholders with respect to the special tax treatment afforded education accounts. Under the Code, neither ordinary income dividends nor capital gain dividends represent current income to shareholders holding shares through an education account.

Distributions from a Qualified Tuition Program account or ESA, including amounts representing earnings on amounts contributed, will not be included in income to the extent they do not exceed the beneficiary’s qualified education expenses, as defined in the Code for purposes of the particular type of account. Education account holders may be subject to a Federal penalty as well as ordinary income tax and any applicable state income tax on the portion of a distribution representing earnings on contributed amounts, if the distribution is not used for qualified education expenses, as defined in the Code for purposes of the particular type of account. Exceptions to the Federal penalty include distributions made on account of the death or disability of the beneficiary of the account and distributions made on account of a scholarship received by the beneficiary, provided the distributions do not exceed the amount of the scholarship.

If an education account becomes ineligible for the special tax treatment described above, the shareholder will be taxed currently on amounts representing accumulated earnings on contributions made to the account. Likewise, dividends paid by the Fund subsequently will be currently taxable, whether received in cash or reinvested, and could be subject to state and local taxes. It is possible that the Federal penalty applicable to withdrawals not used for qualified education expenses might also apply. Disqualification of an education account may subject a nonresident alien shareholder to a 30% United States withholding tax on ordinary income dividends paid by a Fund, unless a reduced rate of withholding is provided under applicable treaty law or such dividends are designated as interest-related dividends or short-term capital gain dividends, as described in “Dividends and Taxes — Taxes — General Treatment of Fund Shareholders.”

The foregoing is a general and abbreviated summary of the applicable provisions of the Code and Treasury regulations presently in effect, as applied to the particular types of Plans and accounts being described. For the complete provisions, reference should be made to the pertinent Code sections and the Treasury regulations promulgated thereunder. The Code and the Treasury regulations are subject to change by legislative, judicial or administrative action either prospectively or retroactively.

Shareholders are urged to consult their tax advisors regarding specific questions as to Federal, foreign, state or local taxes. Foreign investors should consider applicable foreign taxes in their evaluation of investment in each Fund.

II-54

Table of Contents

Shareholders investing through a retirement account or education account, likewise, should consult a tax advisor with respect to the tax consequences of investing through such an account.

Taxes

Each Fund intends to elect and to qualify or to continue to qualify, as appropriate, for the special tax treatment afforded RICs under the Code. As long as a Fund so qualifies, the Fund (but not its shareholders) will not be subject to Federal income tax on the part of its investment company taxable income and net capital gain that is distributed to shareholders. Each Fund intends to distribute substantially all of such income and gains. If, in any taxable year, a Fund fails to qualify as a RIC under the Code, notwithstanding the availability of certain relief provisions, such Fund would be taxed in the same manner as an ordinary corporation and all distributions from earnings and profits (as determined under Federal income tax principles) to its shareholders would be taxable as ordinary dividend income eligible for taxation at a reduced tax rate for non-corporate shareholders and the dividends-received deduction for corporate shareholders.

Each Fund that is a series of a RIC that consists of multiple series is treated as a separate corporation for Federal income tax purposes, and, therefore, is considered to be a separate entity in determining its treatment under the rules for RICs. Losses in one series of a RIC do not offset gains in another, and the requirements (other than certain organizational requirements) for qualifying for RIC status will be determined at the level of the individual series. In the following discussion, the term “Fund” means each individual series, if applicable.

The Code requires a RIC to pay a nondeductible 4% excise tax to the extent the RIC does not distribute, during each calendar year, 98% of its ordinary income, determined on a calendar year basis, and 98.2% of its capital gain net income, determined, in general, as if the RIC’s taxable year ended on October 31, plus certain undistributed amounts from the preceding year. While each Fund intends to distribute its income and capital gains in the manner necessary to minimize imposition of the 4% excise tax, there can be no assurance that sufficient amounts of a Fund’s taxable income and capital gains will be distributed to avoid entirely the imposition of the tax. In such event, a Fund will be liable for the tax only on the amount by which it does not meet the foregoing distribution requirements. The required distributions are based only on the taxable income of a RIC.

General Treatment of Fund Shareholders. Dividends paid by a Fund from its ordinary income or from an excess of net short-term capital gain over net long-term capital loss (together referred to hereafter as “ordinary income dividends”) are taxable to shareholders as ordinary income. Distributions made from an excess of net long-term capital gain over net short-term capital loss (“capital gain dividends”) are taxable to shareholders as long-term capital gain, regardless of the length of time the shareholder has owned Fund shares. Distributions paid by a Fund that are reported as exempt-interest dividends will not be subject to regular Federal income tax. Certain dividend income and long-term capital gains are eligible for taxation at a reduced rate that applies to non-corporate shareholders. Under these rules, the portion of ordinary income dividends constituting “qualified dividend income” when paid by a RIC to non-corporate shareholders may be taxable to such shareholders at long-term capital gain rates. However, to the extent a Fund’s distributions are derived from income on debt securities and short-term capital gains, such distributions will not constitute “qualified dividend income.” Thus, ordinary income dividends paid by the Funds generally will not be eligible for taxation at the reduced rate.

Any loss upon the sale or exchange of Fund shares held for six months or less will be treated as long-term capital loss to the extent of any capital gain dividends received with respect to the shares. Distributions in excess of a Fund’s earnings and profits will first reduce the shareholder’s adjusted tax basis in his shares and any amount in excess of such basis will constitute capital gains to such shareholder (assuming the shares are held as a capital asset). Long-term capital gains ( i.e. , gains from a sale or exchange of capital assets held for more than one year) are generally taxed at preferential rates to non-corporate taxpayers. Each Fund will furnish its shareholders with a written statement reporting the amounts of its dividends paid during the year that qualify as capital gain dividends or exempt-interest dividends, as applicable, as well as the portion of an exempt-interest dividend that constitutes an item of tax preference, as discussed below.

Ordinary income and capital gain dividends are taxable to shareholders even if they are reinvested in additional shares of a Fund. Distributions by a Fund, whether from ordinary income or capital gains, generally will not be eligible for the dividends received deduction allowed to corporations under the Code. If a Fund pays a dividend in January that was declared in the previous October, November or December to shareholders of record on a specified date in one of such months, then such dividend will be treated for tax purposes as being paid by the Fund and received by its shareholders on December 31 of the year in which such dividend was declared.

II-55

Table of Contents

If any Fund (other than a Fund that is a government money market fund) imposes a liquidity fee on share redemptions because of a drop in the Fund’s weekly liquid assets below certain levels, the amount that would ordinarily be payable to a redeeming shareholder of the Fund will be reduced, consequently reducing the amount of gain, or increasing the amount of loss, that would otherwise be reportable for income tax purposes. The liquidity fee cannot be separately claimed as a deduction.

Any such liquidity fee will constitute an asset of the imposing Fund and will serve to benefit non-redeeming shareholders. However, the Funds do not intend to distribute such fees to non-redeeming shareholders. If a Fund receives liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time.

If the value of assets held by a Fund declines, the Trustees of the Fund may authorize a reduction in the number of outstanding shares in shareholders’ accounts so as to preserve a net asset value of $1.00 per share. After such a reduction, the basis of eliminated shares would be added to the basis of shareholders’ remaining Fund shares, and any shareholders disposing of shares at that time may recognize a capital loss. Dividends, including dividends reinvested in additional shares of a Fund, will nonetheless be fully taxable, even if the number of shares in shareholders’ accounts has been reduced as described above.

A loss realized on a sale or exchange of shares of a Fund will be disallowed if other shares of the Fund are acquired (whether through the automatic reinvestment of dividends or otherwise) within a 61 day period beginning 30 days before and ending 30 days after the date on which the shares are sold or exchanged. In such a case, the basis of the shares acquired will be adjusted to reflect the disallowed loss.

Under certain provisions of the Code, some shareholders may be subject to a withholding tax on ordinary income dividends and capital gain dividends (“backup withholding”). Generally, shareholders subject to backup withholding will be non-corporate shareholders for whom no certified taxpayer identification number is on file with a Fund or who, to a Fund’s knowledge, have furnished an incorrect number. When establishing an account, an investor must certify under penalty of perjury that such number is correct and that the investor is not otherwise subject to backup withholding. Backup withholding is not an additional tax. Any amount withheld generally may be allowed as a refund or a credit against a shareholder’s Federal income tax liability provided that the required information is timely provided to the IRS.

If a shareholder recognizes a loss with respect to a Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder in any single taxable year (or a greater amount in a combination of taxable years), the shareholder must file a disclosure statement on Form 8886 with the IRS. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. That a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

A 3.8% Medicare tax is imposed on the net investment income (which includes, but is not limited to, interest, dividends and net gains from investments) of U.S. individuals with income exceeding $200,000, or $250,000 if married filing jointly, and of trusts and estates. However, this tax will not apply to certain amounts that are already excludable from gross income, such as interest on tax-exempt bonds.

Interest received by a Fund may give rise to withholding and other taxes imposed by foreign countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

Ordinary income dividends paid to shareholders that are nonresident aliens or foreign entities generally will be subject to a 30% U.S. withholding tax under existing provisions of the Code applicable to foreign individuals and entities unless a reduced rate of withholding is provided under applicable treaty law. Nonresident shareholders are urged to consult their own tax advisors concerning applicability of the United States withholding tax. Dividends derived by a RIC from short-term capital gains and qualified net interest income (including income from original issue discount and market discount) and paid to stockholders that are nonresident aliens and foreign entities, if and to the extent properly reported as “interest-related dividends” or “short-term capital gain dividends,” generally will not be subject to U.S. withholding tax. Where possible, each Fund intends to report such dividends as interest-related dividends or short-term capital gain dividends. However, depending on its circumstances, a Fund may report all, some or none of its potentially eligible dividends as interest-related dividends or as short-term capital gain dividends, and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder must comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN, W-8BEN-E or substitute form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports the payment as an interest-related dividend or short term capital gain dividend. Non-U.S. shareholders should contact their

II-56

Table of Contents

intermediaries with respect to the application of these rules to their accounts. It is not possible to predict what portion, if any, of a Fund’s distributions will be designated as consisting of qualified short term gain or qualified net interest income exempt from withholding in the hands of nonresident and foreign shareholders.

A 30% withholding tax is currently imposed on dividends and will be imposed on redemption proceeds paid after December 31, 2018 to (i) certain foreign financial institutions and investment funds, and (ii) certain other foreign entities. To avoid withholding, foreign financial institutions and investment funds will generally either need to (a) collect and report to the IRS detailed information identifying their U.S. accounts and U.S. account holders, comply with due diligence procedures for identifying U.S. accounts and withhold tax on certain payments made to noncomplying foreign entities and account holders or (b) if an intergovernmental agreement is entered into and implementing legislation is adopted, comply with the agreement and legislation. Other foreign entities will generally either need to provide detailed information identifying each substantial U.S. owner or certify there are no such owners.

Ordinary income and capital gain dividends paid by the Funds may also be subject to state and local taxes. However, certain states exempt from state income taxation dividends paid by RICs that are derived from interest on United States Treasury obligations. State law varies as to whether dividend income attributable to United States Treasury obligations is exempt from state income tax.

Master — Feeder Funds. In the case of a Feeder Fund, such Fund is entitled to look to the underlying assets of the Master Portfolio in which it has invested for purposes of satisfying various qualification requirements of the Code applicable to RICs. Each Master Portfolio is classified as a partnership for Federal income tax purposes. If applicable tax provisions should change, then the Board of a Feeder Fund will determine, in its discretion, the appropriate course of action for the Feeder Fund. One possible course of action would be to withdraw the Feeder Fund’s investments from the Master Portfolio and to retain an investment manager to manage the Feeder Fund’s assets in accordance with the investment policies applicable to the Feeder Fund.

Proxy Voting Policies and Procedures

The Board of Trustees of each Fund has delegated the voting of proxies for the Funds’ securities to the Manager pursuant to the Manager’s proxy voting guidelines and procedures (the “BlackRock Proxy Voting Guidelines”). Under the BlackRock Proxy Voting Guidelines, the Manager will vote proxies related to Fund securities in the best interests of the Fund and its stockholders. From time to time, a vote may present a conflict between the interests of the Fund’s stockholders, on the one hand, and those of the Manager, or any affiliated person of the Fund or the Manager, on the other. In such event, provided that the Manager’s Equity Investment Policy Oversight Committee, or a sub-committee thereof (the “Committee”) is aware of a real or potential conflict or material non-routine matter and if the Committee does not reasonably believe it is able to follow its general voting guidelines (or if the particular proxy matter is not addressed in the guidelines) and vote impartially, the Committee may retain an independent fiduciary to advise the Committee on how to vote or to cast votes on behalf of the Manager’s clients. If the Manager determines not to retain an independent fiduciary, or does not desire to follow the advice of such independent fiduciary, the Committee shall determine how to vote the proxy after consulting with the Manager’s Portfolio Management Group and/or the Manager’s Legal and Compliance Department and concluding that the vote cast is in its client’s best interest notwithstanding the conflict. Copies of the Funds’ Proxy Voting Policy and the BlackRock Proxy Voting Guidelines are attached as Appendix B. Information on how each Fund voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 is available without charge, (i) at www.blackrock.com and (ii) on the Commission’s website at http://www.sec.gov.

General Information

Shareholders are entitled to one vote for each full share held and fractional votes for fractional shares held and vote in the election of Trustees and generally on other matters submitted to the vote of shareholders. In the case of Retirement Reserves and the BBIF Funds, each class represents an interest in the same assets of the respective Fund and are identical in all respects, except that each class of shares bears certain expenses related to the distribution of such shares and has exclusive voting rights with respect to matters relating to such distribution expenditures. Voting rights are not cumulative, so that the holders of more than 50% of the shares voting in the election of Trustees can, if they choose to do so, elect all Trustees of the Fund. No amendment may be made to the Declaration of Trust without the affirmative vote of a majority of the outstanding shares of the Fund except under certain limited circumstances set forth in the Fund’s Declaration of Trust, as amended (the “Declaration”).

There normally will be no meeting of shareholders for the purpose of electing Trustees unless and until such time as less than a majority of the Trustees holding office have been elected by the shareholders, at which time the

II-57

Table of Contents

Trustees then in office will call a shareholders’ meeting for the election of Trustees. Shareholders may cause a meeting of shareholders to be held in accordance with the terms of the Fund’s Declaration or by-laws, as the case may be. Also, each Fund will be required to call a special meeting of shareholders in accordance with the requirements of the Investment Company Act to seek approval of new advisory arrangements, of a material increase in distribution fees or of a change in fundamental policies, objectives or restrictions. Except as set forth above, the Trustees shall continue to hold office from year to year and appoint successor Trustees. Each issued and outstanding share is entitled to participate equally in dividends and distributions declared and in net assets upon liquidation or dissolution remaining after satisfaction of outstanding liabilities except for any expenses which may be attributable to only one class, in the case of Retirement Reserves, the BBIF Funds or the BlackRock Funds Portfolio. Shares issued are fully-paid and non-assessable by each Fund.

A copy of the Declaration establishing each Fund, together with all amendments thereto, is on file in the office of the Secretary of the Commonwealth of Massachusetts. The Declaration provides that the name of each Fund refers to the Trustees under the Declaration collectively as Trustees, but not as individuals or personally, and no Trustee, shareholder, officer, employee or agent of the Fund shall be held to any personal liability, nor shall resort be had to their property for the satisfaction of any obligation or claim of the Fund but the “Trust Property” (as defined in the Declaration) only shall be liable.

Additional Information

Under a separate agreement, BlackRock has granted the Funds, as applicable, the right to use the “BlackRock” name and has reserved the right to withdraw its consent to the use of such name by a Fund if the Fund ceases to retain BlackRock as investment adviser or to grant the use of such name to any other company.

See Part I, Section VIII “General Information” of each Fund’s SAI for other general information about your Fund.

Description of Bond Ratings

A Description of Moody’s Investors Service, Inc.’s (“Moody’s”) Global Rating Scales

Ratings assigned on Moody’s global long-term and short-term rating scales are forward-looking opinions of the relative credit risks of financial obligations issued by non-financial corporates, financial institutions, structured finance vehicles, project finance vehicles, and public sector entities. Long-term ratings are assigned to issuers or obligations with an original maturity of one year or more and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default. Short-term ratings are assigned to obligations with an original maturity of thirteen months or less and reflect both on the likelihood of a default on contractually promised payments and the expected financial loss suffered in the event of default.

Description of Moody’s Long-Term Obligation Ratings

Aaa	Obligations rated Aaa are judged to be of the highest quality, subject to the lowest level of credit risk.
Aa	Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.
A	Obligations rated A are judged to be upper-medium grade and are subject to low credit risk.
Baa	Obligations rated Baa are judged to be medium-grade and subject to moderate credit risk and as such may possess certain speculative characteristics.
Ba	Obligations rated Ba are judged to be speculative and are subject to substantial credit risk.
B	Obligations rated B are considered speculative and are subject to high credit risk.
Caa	Obligations rated Caa are judged to be speculative of poor standing and are subject to very high credit risk.
Ca	Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.
C	Obligations rated C are the lowest rated and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody’s appends numerical modifiers 1, 2, and 3 to each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Hybrid Indicator (hyb)

The hybrid indicator (hyb) is appended to all ratings of hybrid securities issued by banks, insurers, finance companies, and securities firms. By their terms, hybrid securities allow for the omission of scheduled dividends, interest, or principal payments, which can potentially result in impairment if such an omission occurs. Hybrid securities may also be subject to contractually allowable write-downs of principal that could result in impairment. Together with the hybrid indicator, the long-term obligation rating assigned to a hybrid security is an expression of the relative credit risk associated with that security.

Description of Short-Term Obligation Ratings

Moody’s employs the following designations to indicate the relative repayment ability of rated issuers:

P-1	Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.
P-2	Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.
P-3	Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.
NP	Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

A-1

Table of Contents

Description of Moody’s US Municipal Short-Term Obligation Ratings

The Municipal Investment Grade (“MIG”) scale is used to rate US municipal bond anticipation notes of up to three years maturity. Municipal notes rated on the MIG scale may be secured by either pledged revenues or proceeds of a take-out financing received prior to note maturity. MIG ratings expire at the maturity of the obligation, and the issuer’s long-term rating is only one consideration in assigning the MIG rating. MIG ratings are divided into three levels — MIG 1 through MIG 3 — while speculative grade short-term obligations are designated SG.

MIG 1	This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.
MIG 2	This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.
MIG 3	This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established.
SG	This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

Description of Moody’s Demand Obligation Ratings

In the case of variable rate demand obligations (“VRDOs”), a two-component rating is assigned: a long or short-term debt rating and a demand obligation rating. The first element represents Moody’s evaluation of risk associated with scheduled principal and interest payments. The second element represents Moody’s evaluation of risk associated with the ability to receive purchase price upon demand (“demand feature”). The second element uses a rating from a variation of the MIG scale called the Variable Municipal Investment Grade (“VMIG”) scale.

VMIG 1	This designation denotes superior credit quality. Excellent protection is afforded by the superior short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
VMIG 2	This designation denotes strong credit quality. Good protection is afforded by the strong short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
VMIG 3	This designation denotes acceptable credit quality. Adequate protection is afforded by the satisfactory short-term credit strength of the liquidity provider and structural and legal protections that ensure the timely payment of purchase price upon demand.
SG	This designation denotes speculative-grade credit quality. Demand features rated in this category may be supported by a liquidity provider that does not have an investment grade short-term rating or may lack the structural and/or legal protections necessary to ensure the timely payment of purchase price upon demand.

Description of S& P Global Ratings (“S&P”), a Division of S&P Global Inc., Issue Credit Ratings

A S&P issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects S&P’s view of the obligor’s capacity and willingness to meet its financial commitments as they come due, and may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default.

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. In the U.S., for example, that means obligations with an original maturity of no more than 365 days — including commercial paper. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. Medium-term notes are assigned long-term ratings.

A-2

Table of Contents

Issue credit ratings are based, in varying degrees, on S&P’s analysis of the following considerations:

•	Likelihood of payment — capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;
•	Nature of and provisions of the obligation, and the promise we impute;
•	Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors’ rights.

Long-Term Issue Credit Ratings*

AAA	An obligation rated ‘AAA’ has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.
AA	An obligation rated ‘AA’ differs from the highest-rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment on the obligation is very strong.
A	An obligation rated ‘A’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher-rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.
BBB	An obligation rated ‘BBB’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.
BB; B; CCC; CC; and C	Obligations rated ‘BB’, ‘B’, ‘CCC’, ‘CC’, and ‘C’ are regarded as having significant speculative characteristics. ‘BB’ indicates the least degree of speculation and ‘C’ the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.
BB	An obligation rated ‘BB’ is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions, which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.
B	An obligation rated ‘B’ is more vulnerable to nonpayment than obligations rated ‘BB’, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.
CCC	An obligation rated ‘CCC’ is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.
CC	An obligation rated ‘CC’ is currently highly vulnerable to nonpayment. The ‘CC’ rating is used when a default has not yet occurred, but S&P expects default to be a virtual certainty, regardless of the anticipated time to default.
C	An obligation rated ‘C’ is currently highly vulnerable to nonpayment, and the obligation is expected to have lower relative seniority or lower ultimate recovery compared to obligations that are rated higher.
D	An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.
NR	This indicates that no rating has been requested, or that there is insufficient information on which to base a rating, or that S&P does not rate a particular obligation as a matter of policy.

*The ratings from ‘AA’ to ‘CCC’ may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

A-3

Short-Term Issue Credit Ratings

A-1	A short-term obligation rated ‘A-1’ is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.
A-2	A short-term obligation rated ‘A-2’ is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.
A-3	A short-term obligation rated ‘A-3’ exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.
B	A short-term obligation rated ‘B’ is regarded as vulnerable and has significant speculative characteristics. The obligor currently has the capacity to meet its financial commitments; however, it faces major ongoing uncertainties which could lead to the obligor’s inadequate capacity to meet its financial commitments.
C	A short-term obligation rated ‘C’ is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.
D	A short-term obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless S&P believes that such payments will be made within any stated grace period. However, any stated grace period longer than five business days will be treated as five business days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.

Description of S&P’s Municipal Short-Term Note Ratings

A S&P U.S. municipal note rating reflects S&P’s opinion about the liquidity factors and market access risks unique to the notes. Notes due in three years or less will likely receive a note rating. Notes with an original maturity of more than three years will most likely receive a long-term debt rating. In determining which type of rating, if any, to assign, S&P’s analysis will review the following considerations:

•	Amortization schedule — the larger the final maturity relative to other maturities, the more likely it will be treated as a note; and
•	Source of payment — the more dependent the issue is on the market for its refinancing, the more likely it will be treated as a note.

S&P’s municipal short-term note rating symbols are as follows:

SP-1	Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.
SP-2	Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.
SP-3	Speculative capacity to pay principal and interest.

Description of Fitch Ratings’ (“Fitch’s”) Credit Ratings Scales

Fitch’s credit ratings provide an opinion on the relative ability of an entity to meet financial commitments, such as interest, preferred dividends, repayment of principal, insurance claims or counterparty obligations. Credit ratings are used by investors as indications of the likelihood of receiving the money owed to them in accordance with the terms on which they invested.

Fitch’s credit ratings do not directly address any risk other than credit risk. In particular, ratings do not deal with the risk of a market value loss on a rated security due to changes in interest rates, liquidity and other market considerations. However, in terms of payment obligation on the rated liability, market risk may be considered to the extent that it influences the ability of an issuer to pay upon a commitment. Ratings nonetheless do not reflect market

A-4

Table of Contents

risk to the extent that they influence the size or other conditionality of the obligation to pay upon a commitment (for example, in the case of index-linked bonds).

In the default components of ratings assigned to individual obligations or instruments, the agency typically rates to the likelihood of non-payment or default in accordance with the terms of that instrument’s documentation. In limited cases, Fitch may include additional considerations ( i.e. , rate to a higher or lower standard than that implied in the obligation’s documentation). In such cases, the agency will make clear the assumptions underlying the agency’s opinion in the accompanying rating commentary.

The terms “investment grade” and “speculative grade” have established themselves over time as shorthand to describe the categories ‘AAA’ to ‘BBB’ (investment grade) and ‘BB’ to ‘D’ (speculative grade). The terms “investment grade” and “speculative grade” are market conventions, and do not imply any recommendation or endorsement of a specific security for investment purposes. “Investment grade” categories indicate relatively low to moderate credit risk, while ratings in the “speculative” categories either signal a higher level of credit risk or that a default has already occurred.

A designation of Not Rated or NR is used to denote securities not rated by Fitch where Fitch has rated some, but not all, securities comprising an issuance capital structure.

Description of Fitch’s Long-Term Corporate Finance Obligations Rating Scales

Fitch long-term obligations rating scales are as follows:

AAA	Highest credit quality. ‘AAA’ ratings denote the lowest expectation of credit risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.
AA	Very high credit quality. ‘AA’ ratings denote expectations of very low credit risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.
A	High credit quality. ‘A’ ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.
BBB	Good credit quality. ‘BBB’ ratings indicate that expectations of credit risk are currently low. The capacity for payment of financial commitments is considered adequate but adverse business or economic conditions are more likely to impair this capacity.
BB	Speculative. ‘BB’ ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met.
B	Highly speculative. ‘B’ ratings indicate that material credit risk is present.
CCC	Substantial credit risk. ‘CCC’ ratings indicate that substantial credit risk is present.
CC	Very high levels of credit risk. ‘CC’ ratings indicate very high levels of credit risk.
C	Exceptionally high levels of credit risk. ‘C’ indicates exceptionally high levels of credit risk.

Defaulted obligations typically are not assigned ‘RD’ or ‘D’ ratings, but are instead rated in the ‘B’ to ‘C’ rating categories, depending upon their recovery prospects and other relevant characteristics. This approach better aligns obligations that have comparable overall expected loss but varying vulnerability to default and loss.

Notes: The modifiers “+” or “–” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the ‘AAA’ obligation rating category, or to corporate finance obligation ratings in the categories below ‘CCC’.

The subscript ‘emr’ is appended to a rating to denote embedded market risk which is beyond the scope of the rating. The designation is intended to make clear that the rating solely addresses the counterparty risk of the issuing bank. It is not meant to indicate any limitation in the analysis of the counterparty risk, which in all other respects follows published Fitch criteria for analyzing the issuing financial institution. Fitch does not rate these instruments where the principal is to any degree subject to market risk.

Description of Fitch’s Short-Term Ratings

A short-term issuer or obligation rating is based in all cases on the short-term vulnerability to default of the rated entity or security stream and relates to the capacity to meet financial obligations in accordance with the documentation governing the relevant obligation. Short-Term Ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations and up to 36 months for obligations in U.S. public finance markets.

Fitch short-term ratings are as follows:

F1	Highest short-term credit quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.
F2	Good short-term credit quality. Good intrinsic capacity for timely payment of financial commitments.
F3	Fair short-term credit quality. The intrinsic capacity for timely payment of financial commitments is adequate.
B	Speculative short-term credit quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.
C	High short-term default risk. Default is a real possibility.
RD	Restricted default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Typically applicable to entity ratings only.
D	Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Introduction to BlackRock

BlackRock is the world’s preeminent asset management firm and a premier provider of global investment management, risk management and advisory services to institutional and individual clients around the world. BlackRock offers a wide range of investment strategies and product structures to meet clients’ needs, including individual and institutional separate accounts, mutual funds, closed-end funds, and other pooled investment vehicles and the industry-leading iShares exchange traded funds. Through BlackRock Solutions ^® , we offer risk management, strategic advisory and enterprise investment system services to a broad base of clients.

Philosophy on corporate governance

BlackRock’s corporate governance program is focused on protecting and enhancing the economic value of the companies in which it invests on behalf of clients. We do this through engagement with boards and management of investee companies and, for those clients who have given us authority, through voting at shareholder meetings.

We believe that there are certain fundamental rights attached to share ownership. Companies and their boards should be accountable to shareholders and structured with appropriate checks and balances to ensure that they operate in shareholders’ interests. Effective voting rights are central to the rights of ownership and there should be one vote for one share. Shareholders should have the right to elect, remove and nominate directors, approve the appointment of the auditor and to amend the corporate charter or by-laws. Shareholders should be able to vote on matters that are material to the protection of their investment including but not limited to changes to the purpose of the business, dilution levels and pre-emptive rights, the distribution of income and the capital structure. In order to exercise these rights effectively, we believe shareholders have the right to sufficient and timely information to be able to take an informed view of the proposals, and of the performance of the company and management.

Our focus is on the board of directors, as the agent of shareholders, which should set the company’s strategic aims within a framework of prudent and effective controls which enables risk to be assessed and managed. The board should provide direction and leadership to the management and oversee management’s performance. Our starting position is to be supportive of boards in their oversight efforts on our behalf and we would generally expect to support the items of business they put to a vote at shareholder meetings. Votes cast against or withheld from resolutions proposed by the board are a signal that we are concerned that the directors or management have either not acted in the interests of shareholders or have not responded adequately to shareholder concerns regarding strategy or performance.

These principles set out our approach to engaging with companies, provide guidance on our position on corporate governance and outline how our views might be reflected in our voting decisions. Corporate governance practices vary internationally and our expectations in relation to individual companies are based on the legal and regulatory framework of each market. However, as noted above, we do believe that there are some overarching principles of corporate governance that apply globally. We assess voting matters on a case-by-case basis and in light of each company’s unique circumstances. We are interested to understand from the company’s reporting its approach to corporate governance, particularly where it is different from the usual market practice, and how it benefits shareholders.

BlackRock also believes that shareholders have responsibilities in relation to monitoring and providing feedback to companies, sometimes known as stewardship. These ownership responsibilities include, in our view, engaging with management or board members on corporate governance matters, voting proxies in the best long-term economic interests of shareholders and engaging with regulatory bodies to ensure a sound policy framework consistent with promoting long-term shareholder value creation. Institutional shareholders also have responsibilities to their clients to have appropriate resources and oversight structures. Our own approach to oversight in relation to our corporate governance activities is set out in the section below titled “BlackRock’s oversight of its corporate governance activities”.

Corporate governance, engagement and voting

We recognize that accepted standards of corporate governance differ between markets but we believe that there are sufficient common threads globally to identify an overarching set of principles. The primary objective of our corporate governance activities is the protection and enhancement of the value of our clients’ investments in public corporations. Thus, these principles focus on practices and structures that we consider to be supportive of long-term value creation. We discuss below the principles under six key themes. In our regional and market-specific voting guidelines we explain how these principles inform our voting decisions in relation to specific resolutions that may appear on the agenda of a shareholder meeting in the relevant market.

B-5

Table of Contents

The six key themes are:

•	Boards and directors
•	Auditors and audit-related issues
•	Capital structure, mergers, asset sales and other special transactions
•	Remuneration and benefits
•	Social, ethical and environmental issues
•	General corporate governance matters

At a minimum we would expect companies to observe the accepted corporate governance standard in their domestic market or to explain why doing so is not in the interests of shareholders. Where company reporting and disclosure is inadequate or the approach taken is inconsistent with our view of what is in the best interests of shareholders, we will engage with the company and/or use our vote to encourage a change in practice. In making voting decisions, we take into account research from proxy advisors, other internal and external research, information published by the company or provided through engagement and the views of our equity portfolio managers.

BlackRock views engagement as an important activity; engagement provides BlackRock with the opportunity to improve our understanding of investee companies and their governance structures, so that our voting decisions may be better informed. Engagement also allows us to share our philosophy and approach to investment and corporate governance with companies to enhance their understanding of our objectives. There are a range of approaches we may take in engaging companies depending on the nature of the issue under consideration, the company and the market.

Boards and directors

The performance of the board is critical to the economic success of the company and to the protection of shareholders’ interests. Board members serve as agents of shareholders in overseeing the strategic direction and operation of the company. For this reason, BlackRock focuses on directors in many of its engagements and sees the election of directors as one of its most important responsibilities in the proxy voting context.

We expect the board of directors to promote and protect shareholder interests by:

•	establishing an appropriate corporate governance structure;
•	supporting and overseeing management in setting strategy;
•	ensuring the integrity of financial statements;
•	making decisions regarding mergers, acquisitions and disposals;
•	establishing appropriate executive compensation structures; and
•	addressing business issues including social, ethical and environmental issues when they have the potential to materially impact company reputation and performance.

There should be clear definitions of the role of the board, the sub-committees of the board and the senior management such that the responsibilities of each are well understood and accepted. Companies should report publicly the approach taken to governance (including in relation to board structure) and why this approach is in the interest of shareholders. We will engage with the appropriate directors where we have concerns about the performance of the board or the company, the broad strategy of the company or the performance of individual board members. Concerns about directors may include their role on the board of a different company where that board has performed poorly and failed to protect shareholder interests.

BlackRock believes that directors should stand for re-election on a regular basis. We assess directors nominated for election or re-election in the context of the composition of the board as a whole. There should be detailed disclosure of the relevant credentials of the individual directors in order that shareholders can assess the caliber of an individual nominee. We expect there to be a sufficient number of independent directors on the board to ensure the protection of the interests of all shareholders. Common impediments to independence may include but are not limited to:

•	current employment at the company or a subsidiary;
•	former employment within the past several years as an executive of the company;
•	providing substantial professional services to the company and/or members of the company’s management;
•	having had a substantial business relationship in the past three years;

B-6

Table of Contents

•	having, or representing a shareholder with, a substantial shareholding in the company;
•	being an immediate family member of any of the aforementioned; and
•	interlocking directorships.

BlackRock believes that the operation of the board is enhanced when there is a clearly independent, senior non-executive director to lead it. Where the chairman is also the CEO or is otherwise not independent the company should have an independent lead director. The role of this director is to enhance the effectiveness of the independent members of the board through shaping the agenda, ensuring adequate information is provided to the board and encouraging independent participation in board deliberations. The lead independent board director should be available to shareholders if they have concerns that they wish to discuss.

To ensure that the board remains effective, regular reviews of board performance should be carried out and assessments made of gaps in skills or experience amongst the members. BlackRock believes it is beneficial for new directors to be brought onto the board periodically to refresh the group’s thinking and to ensure both continuity and adequate succession planning. In identifying potential candidates, boards should take into consideration the diversity of experience and expertise of the current directors and how that might be augmented by incoming directors. We believe that directors are in the best position to assess the optimal size for the board, but we would be concerned if a board seemed too small to have an appropriate balance of directors or too large to be effective.

There are matters for which the board has responsibility that may involve a conflict of interest for executives or for affiliated directors. BlackRock believes that shareholders’ interests are best served when the independent members of the board form a sub-committee to deal with such matters. In many markets, these sub-committees of the board specialize in audit, director nominations and compensation matters. An ad hoc committee might also be formed to decide on a special transaction, particularly one with a related party.

Auditors and audit-related issues

BlackRock recognizes the critical importance of financial statements which should provide a complete and accurate picture of a company’s financial condition. We will hold the members of the audit committee or equivalent responsible for overseeing the management of the audit function. We take particular note of cases involving significant financial restatements or ad hoc notifications of material financial weakness.

The integrity of financial statements depends on the auditor being free of any impediments to being an effective check on management. To that end, we believe it is important that auditors are, and are seen to be, independent. Where the audit firm provides services to the company in addition to the audit, the fees earned should be disclosed and explained. Audit committees should also have in place a procedure for assuring annually the independence of the auditor.

Capital structure, mergers, asset sales and other special transactions

The capital structure of a company is critical to its owners, the shareholders, as it impacts the value of their investment and the priority of their interest in the company relative to that of other equity or debt investors. Pre-emption rights are a key protection for shareholders against the dilution of their interests.

In assessing mergers, asset sales or other special transactions, BlackRock’s primary consideration is the long-term economic interests of shareholders. Boards proposing a transaction need to clearly explain the economic and strategic rationale behind it. We will review a proposed transaction to determine the degree to which it enhances long-term shareholder value. We would prefer that proposed transactions have the unanimous support of the board and have been negotiated at arm’s length. We may seek reassurance from the board that executive and/or board members’ financial interests in a given transaction have not affected their ability to place shareholders’ interests before their own. Where the transaction involves related parties, we would expect the recommendation to support it to come from the independent directors and would prefer only non-conflicted shareholders to vote on the proposal.

BlackRock believes that shareholders have a right to dispose of company shares in the open market without unnecessary restriction. In our view, corporate mechanisms designed to limit shareholders’ ability to sell their shares are contrary to basic property rights. Such mechanisms can serve to protect and entrench interests other than those of the shareholders. We believe that shareholders are broadly capable of making decisions in their own best interests. We would expect any so-called ‘shareholder rights plans’ being proposed by a board to be subject to shareholder approval on introduction and periodically thereafter for continuation.

B-7

Table of Contents

Remuneration and benefits

BlackRock expects a company’s board of directors to put in place a compensation structure that incentivizes and rewards executives appropriately and is aligned with shareholder interests, particularly long-term shareholder returns. We would expect the compensation committee to take into account the specific circumstances of the company and the key individuals the board is trying to incentivize. We encourage companies to ensure that their compensation packages incorporate appropriate and challenging performance conditions consistent with corporate strategy and market practice. We use third party research, in addition to our own analysis, to evaluate existing and proposed compensation structures. We hold members of the compensation committee or equivalent accountable for poor compensation practices or structures.

BlackRock believes that there should be a clear link between variable pay and company performance as reflected in returns to shareholders. We are not supportive of one-off or special bonuses unrelated to company or individual performance. We support incentive plans that pay out rewards earned over multiple and extended time periods. We believe consideration should be given to building claw back provisions into incentive plans such that executives would be required to repay rewards where they were not justified by actual performance. Compensation committees should guard against contractual arrangements that would entitle executives to material compensation for early termination of their contract. Finally, pension contributions should be reasonable in light of market practice.

Outside directors should be compensated in a manner that does not risk compromising their independence or aligning their interests too closely with those of the management, whom they are charged with overseeing.

Social, ethical, and environmental issues

Our fiduciary duty to clients is to protect and enhance their economic interest in the companies in which we invest on their behalf. It is within this context that we undertake our corporate governance activities. We believe that well-managed companies will deal effectively with the social, ethical and environmental (“SEE”) aspects of their businesses.

BlackRock expects companies to identify and report on the material, business-specific SEE risks and opportunities and to explain how these are managed. This explanation should make clear how the approach taken by the company best serves the interests of shareholders and protects and enhances the long-term economic value of the company. The key performance indicators in relation to SEE matters should also be disclosed and performance against them discussed, along with any peer group benchmarking and verification processes in place. This helps shareholders assess how well management is dealing with the SEE aspects of the business. Any global standards adopted should also be disclosed and discussed in this context.

We may vote against the election of directors where we have concerns that a company might not be dealing with SEE issues appropriately. Sometimes we may reflect such concerns by supporting a shareholder proposal on the issue, where there seems to be either a significant potential threat or realized harm to shareholders’ interests caused by poor management of SEE matters. In deciding our course of action, we will assess whether the company has already taken sufficient steps to address the concern and whether there is a clear and material economic disadvantage to the company if the issue is not addressed.

More commonly, given that these are often not voting issues, we will engage directly with the board or management. The trigger for engagement on a particular SEE concern is our assessment that there is potential for material economic ramifications for shareholders.

We do not see it as our role to make social, ethical or political judgments on behalf of clients. We expect investee companies to comply, at a minimum, with the laws and regulations of the jurisdictions in which they operate. They should explain how they manage situations where such laws or regulations are contradictory or ambiguous.

General corporate governance matters

BlackRock believes that shareholders have a right to timely and detailed information on the financial performance and viability of the companies in which they invest. In addition, companies should also publish information on the governance structures in place and the rights of shareholders to influence these. The reporting and disclosure provided by companies helps shareholders assess whether the economic interests of shareholders have been protected and the quality of the board’s oversight of management. BlackRock believes shareholders should have the right to vote on key corporate governance matters, including on changes to governance mechanisms, to submit proposals to the shareholders’ meeting and to call special meetings of shareholders.

BlackRock’s oversight of its corporate governance activities

Oversight

BlackRock holds itself to a very high standard in its corporate governance activities, including in relation to executing proxy votes. This function is executed by a team of dedicated BlackRock employees without sales responsibilities (the “Corporate Governance Group”), and which is considered an investment function. BlackRock maintains three regional oversight committees (“Corporate Governance Committees”) for the Americas, Europe, the Middle East and Africa (EMEA) and Asia-Pacific, consisting of senior BlackRock investment professionals. All of the regional Corporate Governance Committees report to a Global Corporate Governance Oversight Committee, which is a risk-focused committee composed of senior representatives of the active and index equity investment businesses, the Deputy General Counsel, the Global Executive Committee member to whom the Corporate Governance Group reports and the head of the Corporate Governance Group. The Corporate Governance Committees review and approve amendments to their respective proxy voting guidelines (“Guidelines”) and grant authority to the Global Head of Corporate Governance (“Global Head”), a dedicated BlackRock employee without sales responsibilities, to vote in accordance with the Guidelines. The Global Head leads the Corporate Governance Group to carry out engagement, voting and vote operations in a manner consistent with the relevant Corporate Governance Committee’s mandate. The Corporate Governance Group engages companies in conjunction with the portfolio managers in discussions of significant governance issues, conducts research on corporate governance issues and participates in industry discussions to keep abreast of the field of corporate governance. The Corporate Governance Group, or vendors overseen by the Corporate Governance Group, also monitor upcoming proxy votes, execute proxy votes and maintain records of votes cast. The Corporate Governance Group may refer complicated or particularly controversial matters or discussions to the appropriate investors and/or regional Corporate Governance Committees for their review, discussion and guidance prior to making a voting decision.

BlackRock’s Equity Policy Oversight Committee (EPOC) is informed of certain aspects of the work of the Global Corporate Governance Oversight Committee and the Corporate Governance Group.

Vote execution

BlackRock carefully considers proxies submitted to funds and other fiduciary accounts (“Funds”) for which it has voting authority. BlackRock votes (or refrains from voting) proxies for each Fund for which it has voting authority based on BlackRock’s evaluation of the best long-term economic interests of shareholders, in the exercise of its independent business judgment, and without regard to the relationship of the issuer of the proxy (or any dissident shareholder) to the Fund, the Fund’s affiliates (if any), BlackRock or BlackRock’s affiliates.

When exercising voting rights, BlackRock will normally vote on specific proxy issues in accordance with its Guidelines for the relevant market. The Guidelines are reviewed regularly and are amended consistent with changes in the local market practice, as developments in corporate governance occur, or as otherwise deemed advisable by BlackRock’s Corporate Governance Committees. The Corporate Governance Committees may, in the exercise of their business judgment, conclude that the Guidelines do not cover the specific matter upon which a proxy vote is requested or that an exception to the Guidelines would be in the best long-term economic interests of BlackRock’s clients.

In the uncommon circumstance of there being a vote with respect to fixed income securities or the securities of privately held issuers the decision generally will be made by a Fund’s portfolio managers and/or the Corporate Governance Group based on their assessment of the particular transactions or other matters at issue.

In certain markets, proxy voting involves logistical issues which can affect BlackRock’s ability to vote such proxies, as well as the desirability of voting such proxies. These issues include but are not limited to: (i) untimely notice of shareholder meetings; (ii) restrictions on a foreigner’s ability to exercise votes; (iii) requirements to vote proxies in person; (iv) “share-blocking” (requirements that investors who exercise their voting rights surrender the right to dispose of their holdings for some specified period in proximity to the shareholder meeting); (v) potential difficulties in translating the proxy; and (vi) requirements to provide local agents with unrestricted powers of attorney to facilitate voting instructions. We are not supportive of impediments to the exercise of voting rights such as shareblocking or overly burdensome administrative requirements.

As a consequence, BlackRock votes proxies in these markets only on a “best-efforts” basis. In addition, the Corporate Governance Committees may determine that it is generally in the best interests of BlackRock clients not to vote proxies of companies in certain countries if the committee determines that the costs (including but not limited

B-9

Table of Contents

to opportunity costs associated with shareblocking constraints) associated with exercising a vote are expected to outweigh the benefit the client would derive by voting on the issuer’s proposal.

While it is expected that BlackRock, as a fiduciary, will generally seek to vote proxies over which BlackRock exercises voting authority in a uniform manner for all BlackRock clients, the relevant Corporate Governance Committee, in conjunction with the portfolio manager of an account, may determine that the specific circumstances of such an account require that such account’s proxies be voted differently due to such account’s investment objective or other factors that differentiate it from other accounts. In addition, BlackRock believes portfolio managers may from time to time legitimately reach differing but equally valid views, as fiduciaries for their funds and the client assets in those Funds, on how best to maximize economic value in respect of a particular investment. Accordingly, portfolio managers retain full discretion to vote the shares in the Funds they manage based on their analysis of the economic impact of a particular ballot item.

Conflicts management

BlackRock maintains policies and procedures that are designed to prevent undue influence on BlackRock’s proxy voting activity that might stem from any relationship between the issuer of a proxy (or any dissident shareholder) and BlackRock, BlackRock’s affiliates, a Fund or a Fund’s affiliates. Some of the steps BlackRock has taken to prevent conflicts include, but are not limited to:

•	BlackRock has adopted a proxy voting oversight structure whereby the Corporate Governance Committees oversee the voting decisions and other activities of the Corporate Governance Group, and particularly its activities with respect to voting in the relevant region of each Corporate Governance Committee’s jurisdiction.
•	The Corporate Governance Committees have adopted Guidelines for each region, which set forth the firm’s views with respect to certain corporate governance and other issues that typically arise in the proxy voting context. The Corporate Governance Committees receive periodic reports regarding the specific votes cast by the Corporate Governance Group and regular updates on material process issues, procedural changes and other matters of concern to the Corporate Governance Committees.
•	BlackRock’s Global Corporate Governance Oversight Committee oversees the Global Head, the Corporate Governance Group and the Corporate Governance Committees. The Global Corporate Governance Oversight Committee conducts a review, at least annually, of the proxy voting process to ensure compliance with BlackRock’s risk policies and procedures.
•	BlackRock maintains a reporting structure that separates the Global Head and Corporate Governance Group from employees with sales responsibilities. In addition, BlackRock maintains procedures intended to ensure that all engagements with corporate issuers or dissident shareholders are managed consistently and without regard to BlackRock’s relationship with the issuer of the proxy or dissident shareholder. Within the normal course of business, the Global Head or Corporate Governance Group may engage directly with BlackRock clients, and with employees with sales responsibilities, in discussions regarding general corporate governance policy matters, and to otherwise ensure that proxy-related client service levels are met. The Global Head or Corporate Governance Group does not discuss any specific voting matter with a client prior to the disclosure of the vote decision to all applicable clients after the shareholder meeting has taken place, except if the client is acting in the capacity as issuer of the proxy or dissident shareholder and is engaging through the established procedures independent of the client relationship.
•	In certain instances, BlackRock may determine to engage an independent fiduciary to vote proxies as a further safeguard to avoid potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BlackRock with instructions as to how to vote such proxies. In the latter case, BlackRock votes the proxy in accordance with the independent fiduciary’s determination. Use of an independent fiduciary has been adopted for voting the proxies related to any company that is affiliated with BlackRock or any company that includes BlackRock employees on its board of directors.

With regard to the relationship between securities lending and proxy voting, BlackRock’s approach is driven by our clients’ economic interests. The evaluation of the economic desirability of recalling loans involves balancing the revenue producing value of loans against the likely economic value of casting votes. Based on our evaluation of this relationship, we believe that generally the likely economic value of casting most votes is less than the securities lending income, either because the votes will not have significant economic consequences or because the outcome of the vote would not be affected by BlackRock recalling loaned securities in order to ensure they are voted. Periodically, BlackRock analyzes the process and benefits of voting proxies for securities on loan, and will consider whether any modification of its proxy voting policies or procedures is necessary in light of future conditions. In

addition, BlackRock may in its discretion determine that the value of voting outweighs the cost of recalling shares, and thus recall shares to vote in that instance.

Voting guidelines

The issue-specific voting Guidelines published for each region/country in which we vote are intended to summarize BlackRock’s general philosophy and approach to issues that may commonly arise in the proxy voting context in each market where we invest. These Guidelines are not intended to be exhaustive. BlackRock applies the Guidelines on a case-by-case basis, in the context of the individual circumstances of each company and the specific issue under review.

As such, these Guidelines do not provide a guide to how BlackRock will vote in every instance. Rather, they share our view about corporate governance issues generally, and provide insight into how we typically approach issues that commonly arise on corporate ballots.

Reporting

We report our proxy voting activity directly to clients and publically as required. In addition, we publish for clients a more detailed discussion of our corporate governance activities, including engagement with companies and with other relevant parties.

The Trust shall indemnify each of its Trustees against all liabilities and expenses (including amounts paid in satisfaction of judgments, in compromise, as fines and penalties, and as counsel fees) reasonably incurred by him in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, in which he may be involved or with which he may be threatened, while as a Trustee or thereafter, by reason of his being or having been such a Trustee except with respect to any matter as to which he shall have been adjudicated to have acted in bad faith, willful misfeasance, gross negligence or reckless disregard of his duties, provided that as to any matter disposed of by a compromise payment by such person, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless the Trust shall have received a written opinion from independent legal counsel approved by the Trustees to the effect that if either the matter of willful misfeasance, gross negligence or reckless disregard of duty, or the matter of bad faith had been adjudicated, it would in the opinion of such counsel have been adjudicated in favor of such person. The rights accruing to any person under these provisions shall not exclude any other right to which he may be lawfully entitled, provided that no person may satisfy any right of indemnity or reimbursement hereunder except out of the property of the Trust. The Trustees may make advance payments in connection with the indemnification under this Section 9.3, provided that the indemnified person shall have given a written undertaking to reimburse the Trust in the event it is subsequently determined that he is not entitled to such indemnification.

The Trustee shall indemnify officers, representatives and employees of the Trust to the same extent that Trustees are entitled to indemnification pursuant to this Section 9.3.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to trustees, officers and controlling persons of Registrant pursuant to the foregoing provisions, or otherwise, Registrant has been advised

C-13

that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a trustee, officer or controlling person of Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the securities being registered, Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Section 9.6 of the Registrant’s Declaration of Trust, filed herein as Exhibit 1(a), also provides for the indemnification of shareholders of the Registrant. Section 9.6 states as follows:

Indemnification of Shareholders. In case any Shareholder or former Shareholder shall be held to be personally liable solely by reason of his being or having been a Shareholder and not because of his acts or omissions or for some other reason, the Shareholder or former Shareholder (or his heirs, executors, administrators or other legal representatives or, in the case of a corporation or other entity, its corporate or other general successor) shall be entitled out of the assets belonging to the classes of Shares with the same alphabetical designation as that of the Shares owned by such Shareholder to be held harmless from and indemnified against all loss and expense arising from such liability. The Trust shall, upon request by the Shareholder, assume the defense of any claim made against any Shareholder for any act or obligations of the Trust and satisfy any judgment thereon from such assets.
