TABLE OF CONTENTS

PART I: INFORMATION ABOUT CIRCLE RESERVE FUND

Part I of this Statement of Additional Information (“SAI”) sets forth information about Circle Reserve Fund (“Circle Reserve” 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 applicable to 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 government money market fund under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

Please see the section “Details About the Fund — How the Fund Invests” in the Fund’s Prospectuses for information about the Fund’s investment objective and policies.

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

All securities acquired by the Fund will be determined at the time of purchase by BlackRock to be “Eligible Securities” as defined by the 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 must include, to the extent appropriate, consideration of the following factors with respect to the security’s issuer or guarantor:

2. That is issued by a registered investment company that is a money market fund; or

3. That issued or guaranteed as to principal or interest by the U.S. Government or any of its agencies or instrumentalities.

* * *

Set forth below is a listing of some of the types of investments and investment strategies that the Fund may use, and the risks and considerations associated with those investments and investment strategies. Please see Part II of this SAI for further information on these investments and investment strategies. Information contained in Part II about the risks and considerations associated with investments and/or investment strategies applies only to the extent the Fund makes each type of investment or uses each investment strategy.Also set forth below is a listing of the proxy voting policy and related guidelines applicable to the Fund. Please see “Proxy Voting Policies and Procedures” in Part II of this SAI for further information about these policies. A copy of each policy is included in Appendix B. Information that does not apply to the Fund does not form a part of the Fund’s SAI and should not be relied on by investors in the Fund.

I-1

Only information that is clearly identified as applicable to the Fund is considered to form a part of the Fund’s SAI.

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) 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

I-2

With respect to the fundamental policy relating to borrowing money set forth in (2) above, the Investment Company Act permits the Fund to borrow money in amounts of up to one-third of the Fund’s total assets from banks for any purpose, and to borrow up to 5% of the Fund’s total assets from banks or other lenders for temporary purposes. (The Fund’s total assets include the amounts being borrowed.) To limit the risks attendant to borrowing, the Investment Company Act requires the Fund to maintain at all times an “asset coverage” of at least 300% of the amount of its borrowings. Asset coverage means the ratio that the value of the Fund’s total assets (including amounts borrowed), minus liabilities other than borrowings, bears to the aggregate amount of all borrowings. The policy in (2) above will be interpreted to permit the Fund to engage in trading practices and investments that may be considered to be borrowing or to involve leverage to the extent permitted by the Investment Company Act. Short-term credits necessary for the settlement of securities transactions and arrangements with respect to securities lending will not be considered to be borrowings under the policy. Practices and investments that may involve leverage but are not considered to be borrowings are not subject to the policy. The Fund does not currently intend to borrow for investment purposes.

With respect to the fundamental policy relating to underwriting set forth in (5) above, the Investment Company Act does not prohibit the Fund from engaging in the underwriting business or from underwriting the securities of other issuers; in fact, in the case of diversified funds, the Investment Company Act permits a fund to have underwriting commitments of up to 25% of its assets under certain circumstances. Those circumstances currently are that the amount of the fund’s underwriting commitments, when added to the value of the fund’s investments in issuers where the fund owns more than 10% of the outstanding voting securities of those issuers, cannot exceed the 25% cap. A fund engaging in transactions involving the acquisition or disposition of portfolio securities may be considered to be an underwriter under the Securities Act of 1933, as amended (the “Securities Act”). Although it is not believed that the application of the Securities Act provisions described above would cause the Fund to be engaged in the business of underwriting, the policy in (5) above will be interpreted not to prevent the Fund from engaging in transactions involving the acquisition or disposition of portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the Securities Act or is otherwise engaged in the underwriting business to the extent permitted by applicable law.

With respect to the fundamental policy relating to lending set forth in (7) above, the Investment Company Act does not prohibit the Fund from making loans (including lending its securities); however, Commission staff interpretations currently prohibit funds from lending more than one-third of their total assets (including lending its securities), except through the purchase of debt obligations or the use of repurchase agreements. In addition, collateral arrangements with respect to options, forward currency and futures transactions and other derivative instruments (as applicable), as well as delays in the settlement of securities transactions, will not be considered loans.

The Fund is currently classified as a diversified fund under the Investment Company Act. Pursuant to Rule 2a-7 under the Investment Company Act, a money market fund that satisfies the applicable diversification requirements of Rule 2a-7 shall be deemed to have satisfied the diversification requirements of the Investment Company Act and the rules adopted thereunder. 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. Additionally, pursuant to Rule 2a-7, the Fund will generally not invest more than 10% of its total assets in securities issued by or subject to demand features or guarantees from the institutional that issued the demand feature or guarantee. Under the Investment Company Act, the Fund cannot change its classification from diversified to non-diversified without shareholder approval (including class approval by preferred shareholders, if any).

I-4

Under its non-fundamental investment restrictions, which may be changed by the Board without shareholder approval, the Fund may not:

a. Purchase securities of other investment companies, except to the extent permitted by the Investment Company Act. As a matter of policy, however, the Fund will not purchase shares of any registered open-end investment company or registered unit investment trust, in reliance on Section 12(d)(1)(F) or (G) (the “fund of funds” provisions) of the Investment Company Act, at any time the Fund has knowledge that its shares are purchased by another investment company investor in reliance on the provisions of subparagraph (G) of Section 12(d)(1).

b. Make short sales of securities or maintain a short position, except to the extent permitted by the Fund’s Prospectus and SAI, as amended from time to time, and applicable law.

Unless otherwise indicated, all limitations under the Fund’s fundamental or non-fundamental investment restrictions 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 BlackRock determines that it is practicable to sell or close out the investment without undue market or tax consequences.

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 the Manager or its affiliates (the “BlackRock-advised Funds”) are organized into the BlackRock Multi-Asset Complex, the BlackRock Fixed-Income Complex, and the iShares Complex (each, a “BlackRock Fund Complex”). The Trust is included in the BlackRock Fund Complex referred to as the BlackRock Multi-Asset Complex. The Trustees also oversee as board members the operations of the other open-end registered investment companies included in the BlackRock Multi-Asset 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 Committee and an Ad Hoc Topics 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 Fund 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 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 objective 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

I-5

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 Trust’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.

Audit Committee. The members of the Audit Committee (the “Audit Committee”) are Henry R. Keizer (Chair), Neil A. Cotty, Lori Richards, Kenneth L. Urish and Claire A. Walton, 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 Fund’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 Governance Committee may consider nominations for Trustees made by the Fund’s shareholders as it deems appropriate. Under the Trust’s Amended and Restated Code of Regulations (“Bylaws”), shareholders must follow certain procedures to nominate a person for election as a Trustee at a shareholder meeting at which Trustees are to be elected. Under these advance notice procedures, notice of the proposed nominee to the Secretary of the Trust must be delivered to or mailed and received at the principal executive offices of the Trust not later than the close of business on the fifth day following the day on which notice of the date of the meeting was mailed or public disclosure of the date of the meeting was made, whichever first occurs. The Trust’s Bylaws provide that notice of a proposed nomination must include certain information about the shareholder and the

I-6

nominee, as well as certain other information, including a written consent of the proposed nominee to serve if elected. Reference is made to the Trust’s Bylaws for more details. The Board has adopted a written charter for the Governance Committee. During the fiscal year ended April 30, 2025, the Governance Committee met four times.

Compliance Committee. The members of the Compliance Committee (the “Compliance Committee”) are Claire A. Walton (Chair), Cynthia A. Montgomery, Donald C. Opatrny, Lori Richards and Kenneth L. Urish, 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 April 30, 2025, the Compliance Committee met four times.

Performance Oversight Committee. The members of the Performance Oversight Committee (the “Performance Oversight Committee”) are Donald C. Opatrny (Chair), Christopher J. Ailman, Susan J. Carter, Collette Chilton and Neil A. Cotty, 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 objective, 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 April 30, 2025, the Performance Oversight Committee met five times.

Ad Hoc Topics Committee. The members of the Ad Hoc Topics Committee (the “Ad Hoc Topics Committee”) are Mark Stalnecker (Chair) and Claire A. Walton, both of whom are Independent Trustees, and John M. Perlowski, who serves as an interested Trustee. The principal responsibilities of the Ad Hoc Topics 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 Ad Hoc Topics Committee by the Board. The Board has adopted a written charter for the Ad Hoc Topics Committee. During the fiscal year ended April 30, 2025, the Ad Hoc Topics Committee did not meet.

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

I-7

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 investment funds, public companies, non-profit entities or other organizations; ongoing commitment to and participation in Board and Committee meetings, as well as his or her leadership of standing and ad hoc committees throughout the years; or other relevant life experiences.

The table below discusses some of the experiences, qualifications and skills of each of the Trustees that support the conclusion that each Trustee should serve on the Board.

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.

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 Fund shares for various reasons may not be comparable to the yield on bank deposits, shares of other money market funds or other investments.

I-16

The yield on the Fund’s Institutional Shares for the seven-day period ended April 30, 2025 was 4.28%.

See “Portfolio Transactions” in Part II of this SAI for more information.

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. 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

I-17

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.

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 prospectuses (the “Prospectus”) and the “Investment Objective and Policies,” “Investment Objectives and Policies” or “Investment Strategies and Risks of the Fund” as applicable, 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 SAI 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 SAI.

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. 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

II-1

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 certain Funds invest must be issued by depository institutions with total assets of at least $1 billion, except that such Funds 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 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, Authorized Participants, service providers and the relevant listing exchange are 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 adviser, sub-adviser(s) and other service providers (including, but not limited to, index providers, Fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or 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 (“NAV”), disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, 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

II-2

issuers in which the Funds invest, market makers or Authorized Participants. The Funds and their shareholders could be negatively impacted as a result.

Environmental, Social and Governance (“ESG”) Integration. Although a Fund does not seek to implement a specific sustainability objective, strategy or process unless disclosed in the Fund’s Prospectus, BlackRock will consider ESG factors as part of the credit research and investment process for a Fund. BlackRock views ESG integration as the practice of incorporating financially material ESG data or information into investment processes with the objective of enhancing risk-adjusted returns. All securities purchases by a Fund are selected from approved lists maintained by BlackRock. All instruments on an approved list used by a Fund have met the minimal credit risk requirement of Rule 2a-7, if required. In reviewing instruments, BlackRock will consider the capacity of the issuer or guarantor to meet its obligations. BlackRock considers ESG data within the total data available during its review. This may include third party research as well as considerations of proprietary BlackRock research across the ESG risks and opportunities regarding an issuer.

The ESG characteristics utilized in a Fund’s investment processes are anticipated to evolve over time and one or more characteristics may not be relevant with respect to all issuers that are eligible for investment. Certain of these considerations may affect the Fund’s exposure to certain companies or industries. While BlackRock views ESG considerations as having the potential to contribute to a Fund’s long-term performance, there is no guarantee that such results will be achieved.

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 NAV. The value of the security on the delivery date may be more or less than its purchase price. 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.

Illiquid Investments. No Fund will 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 Manager will monitor the liquidity of illiquid investments under the supervision of the Board.

Inflation Risk. The Funds are subject to inflation risk. Inflation risk is the risk that the present value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the present value of a Fund’s assets can decline as can the value of a Fund’s distributions.

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

II-3

funds (“ETFs”), which are typically open-end funds or unit investment trusts listed on a stock exchange. Under Section 12(d)(1)(A) of the Investment Company Act, however, 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 Section 12(d)(1)(A) of 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, under Section 12(d)(1)(C) of the Investment Company Act 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 Section 12(d)(1)(G) of the Investment Company Act, these percentage limitations do not apply to investments in affiliated investment companies, including ETFs, subject to certain conditions. In addition, a Fund may be able to rely on certain rules under the Investment Company Act to invest in shares of money market funds or other investment companies beyond the statutory limits noted above, but subject to certain conditions.

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

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 NAVs. In addition, investment companies held by a Fund that trade on an exchange could trade at a discount from NAV, 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 another fund, the ability of the Fund itself to purchase other funds 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 underlying funds if such underlying funds themselves own shares of underlying 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.

Issuer Insolvency Risk. Certain Funds’ potential exposure to financially or operationally troubled issuers involves a high degree of credit and market risk, which may be heightened during an economic downturn or recession. Should an issuer of securities held by a Fund become involved in a bankruptcy proceeding, reorganization or financial restructuring, a wide variety of considerations make an evaluation of the outcome of the Fund’s exposure to the issuer uncertain.

During the period of a bankruptcy proceeding, reorganization or financial restructuring, it is unlikely that a Fund will receive any interest payments on the securities of the issuer. A Fund will be subject to significant uncertainty as to whether the reorganization or restructuring will be completed, and the Fund may bear certain extraordinary expenses to protect and recover its investment. A Fund will also be subject to significant uncertainty as to when and in what manner and for what value the obligations evidenced by the securities of the issuer held by the Fund will eventually be satisfied.

II-4

Even if a plan of reorganization or restructuring is adopted with respect to the securities of the issuer held by the Fund, there can be no assurance that the securities or other assets received by a Fund in connection with such plan of reorganization or restructuring will not have a lower value or income potential than may have been anticipated or no value. A Fund may be unable to enforce its claims or rights in any collateral or may have its claims or security interest in any collateral challenged, disallowed or subordinated to the claims or security interests of other creditors. In addition, amendments to the U.S. Bankruptcy Code or other relevant laws could alter the expected outcome or introduce greater uncertainty regarding the outcome of the Fund’s securities holdings in the issuer. In a bankruptcy proceeding, a reorganization or restructuring, the securities of the issuer held by a Fund could be re-characterized or a Fund may receive different securities or other assets, including equity securities. These types of equity securities include, but are not limited to: common stock; preferred stock (including convertible preferred stock); bonds, notes and debentures convertible into common or preferred stock; stock purchase warrants and rights; equity interests in trusts; and depositary receipts. Equity securities are subject to changes in value, and their value may be more volatile than those of other asset classes. Holders of equity securities are subject to more risk than holders of debt securities because the status of equity holders is subordinate to debtholders in an issuer’s capital structure. The value of equity securities received by a Fund could decline if the financial condition of the issuer deteriorates or if overall market and economic conditions, or conditions within the issuer’s region or industry, deteriorate.

To the extent that a Fund receives other assets in connection with a bankruptcy proceeding, reorganization or financial restructuring, the Fund may also be subject to additional risks associated with the assets received. One example of assets that a Fund could receive is an interest in one or more loans made to the issuer as part of a workout agreed to by a consortium of lienholders and creditors of the issuer. A Fund may receive such interests in loans to the extent permitted by the 1940 Act.

Securities or other assets received in a reorganization or restructuring typically entail a higher degree of risk than investments in securities of issuers that have not undergone a reorganization or restructuring and may be subject to heavy selling or downward pricing pressure after completion of the reorganization or restructuring. The post-reorganization/restructuring assets and securities may also be illiquid and difficult to sell or value. If a Fund participates in negotiations with respect to a plan of reorganization or restructuring with respect to securities of the issuer held by a Fund, the Fund also may be restricted from disposing such securities for a period of time. If a Fund becomes involved in such proceedings, the Fund may have more active participation in the affairs of the issuer than that assumed generally by an investor.

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 Federal

II-5

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 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

II-6

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.

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 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”) 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 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” 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) 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.”

II-7

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. 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. 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 may not be honored. The interest rates are adjustable at periodic intervals 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 Securities Industry and Financial Markets Association (“SIFMA”) Municipal Swap 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.

Because of the interest rate adjustment formula on 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.

Negative Interest Rate Scenarios. Should a negative interest rate scenario ever occur that causes a government or retail money market fund to have a negative gross yield, the fund may account for the negative gross yield by either using a floating NAV or a reverse distribution mechanism that seeks to maintain a stable net asset value of the fund by cancelling shareholders’ shares in the amount of the negative gross yield. If a fund converts to a floating NAV, any losses the fund experiences due to negative interest rates will be reflected in a declining NAV per share. Under a reverse distribution mechanism, shareholders in a fund would observe a stable share price but a declining number of shares for their investment. This means that such an investor would lose money when the fund cancels shares. In either situation, the Board will need to determine that the approach is in the best interests of the fund and will need to ensure shareholders are provided adequate disclosures around the consequences of the approach chosen by the Board for the fund.

II-8

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 that enable certain Funds to dispose of such a security at a time when the market value of the security approximates its par value.

Recent Market Events. Since the market stresses associated with the 2008 financial crisis in the United States and global economies, periods of unusually high volatility in the financial markets and restrictive credit conditions, sometimes limited to a particular sector or a geography, continue to recur. Some countries, including the United States, have adopted and/or are considering the adoption of more protectionist trade policies, a move away from the tighter financial industry regulations that followed the financial crisis, and/or substantially reducing corporate taxes. The exact shape of these policies is still being considered, but the equity and debt markets may react strongly to expectations of change, which could increase volatility, especially if the market’s expectations are not borne out. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, geopolitical and other risks, including environmental and public health, may add to instability in world economies and markets generally. Economies and financial markets throughout the world are becoming increasingly interconnected. As a result, whether or not a Fund invests in securities of issuers located in or with significant exposure to countries experiencing economic, political and/or financial difficulties, the value and liquidity of the Fund’s investments may be negatively affected by such events.

Governments and regulators may take actions that affect the regulation of the Fund or the instruments in which the Fund invests, or the issuers of such instruments, in ways that are unforeseeable. Future legislation or regulation or other governmental actions could limit or preclude the Fund’s abilities to achieve its investment objectives or otherwise adversely impact an investment in the Fund. Recent policy initiatives undertaken by the U.S. government have the potential to impact international relations, trade agreements and the overall regulatory environment in ways that could create uncertainty and instability in domestic and global markets, and could adversely affect the investment performance of the Fund. In particular, actions taken by the U.S. government in respect of international trade relations could lead to trade wars, increased costs for imported goods, disruptions in supply chains, reduced foreign investment, and instability in regions where the Fund invests. Political and diplomatic events within the United States, including a contentious domestic political environment, changes in political party control of one or more branches of the U.S. Government, the U.S. Government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a U.S. Government shutdown, and disagreements over, or threats not to increase, the U.S. Government’s borrowing limit (or “debt ceiling”), as well as political and diplomatic events abroad, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. A downgrade of the ratings of U.S. Government debt obligations, or concerns about the U.S. Government’s credit quality in general, could have a substantial negative effect on the U.S. and global economies. For example, concerns about the U.S. Government’s credit quality may cause increased volatility in the stock and bond markets, higher interest rates, reduced prices and liquidity of U.S. Treasury securities, and/or increased costs of various kinds of debt. Moreover, although the U.S. Government has honored its credit obligations, there remains a possibility that the United States could default on its obligations. The consequences of such an unprecedented event are impossible to predict, but it is likely that a default by the United States would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the Fund’s investments.

An outbreak of respiratory disease caused by a novel coronavirus (COVID-19) that was first detected in December 2019 developed into a global pandemic. This pandemic resulted in closing borders, enhanced health screenings, healthcare service preparation and delivery, quarantines, cancellations, disruptions to supply chains and customer activity, as well as general concern and uncertainty for a period of time. The impact of this outbreak has adversely affected the economies of many nations and the entire global economy and impacted individual issuers and capital. Other infectious illness outbreaks that may arise in the future could have similar or other unforeseen effects. The duration of any such outbreak and its effects cannot be determined with certainty.

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

II-9

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 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.

Regulations adopted by global prudential regulators that are now in effect require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many repurchase agreements and purchase and sale contracts, terms that delay or restrict the rights of counterparties, such as a Fund, to terminate such agreements, take foreclosure action, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these new requirements, as well as potential additional government regulation and other developments in the market, could adversely affect a Fund’s ability to terminate existing repurchase agreements and purchase and sale contracts or to realize amounts to be received under such agreements.

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. 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

II-10

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.

Additionally, regulations adopted by global prudential regulators that are now in effect require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many reverse repurchase agreements, terms that delay or restrict the rights of counterparties, such as a Fund, to terminate such agreements, take foreclosure action, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these new requirements, as well as potential additional government regulation and other developments in the market, could adversely affect a Fund’s ability to terminate existing reverse repurchase agreements or to realize amounts to be received under such agreements.

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 based on its market value 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 or the period remaining until the principal amount can be recovered through demand 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 25% 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 50% 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 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.

II-11

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 discretionary liquidity fees. The Board of Trustees has determined that each Fund that is a government money market fund will not be subject to discretionary liquidity fees under Rule 2a-7.

Retail Money Market Funds. A retail money market fund is a money market fund that has policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. Under Rule 2a-7, a retail money market fund is subject to the discretionary liquidity fees provisions; however, a retail money market fund is permitted to use the amortized cost method of accounting or the penny rounding method, allowing a retail money market fund to maintain a stable NAV.

Securities Lending. Each Fund may lend portfolio securities to certain borrowers that BlackRock determines to be creditworthy, including 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 receives, by way of substitute payment, 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 any positive 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 reinvested in certain short-term instruments either directly on behalf of the Fund or through one or more joint accounts or money market funds, including those affiliated with BlackRock; 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), foreign exchange risk (i.e., the risk of a shortfall at default when a cash collateral investment is denominated in a currency other than the currency of the assets being loaned due to movements in foreign exchange rates), and credit, legal, counterparty and market risks (including the risk that market events, including but not limited to corporate actions, could lead a Fund to lend securities that are trading at a premium due to increased demand, or to recall loaned securities or to lend less or none at all, which could lead to reduced securities lending revenue). If a Fund were to lend out securities that are subject to a corporate action and commit to the borrower a particular election as determined by the Fund’s investment adviser, the benefit the Fund would receive in respect of committing to such election may or may not be less than the benefit the Fund would have received from making a different election in such corporate action. 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’s ability to participate in a corporate action event may be impacted, or 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 latter 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 received by a Fund representing dividends paid on securities loaned out by the Fund will not be considered qualified dividend income, and distributions by the Fund of such substitute payments will not constitute qualified dividend income. Additionally, substitute payments received by a Fund representing qualified REIT dividends paid on REIT securities loaned out by the Fund will not be considered qualified REIT dividends, and distributions by the Fund of such substitute payments will not be eligible for a 20% deduction currently available for ordinary REIT dividends paid to non-corporate shareholders provided certain other requirements are satisfied. The securities lending agent will take into account the tax effects on shareholders caused by these differences in connection with a Fund’s securities lending program. Substitute payments received on tax-exempt securities loaned out will not be tax-exempt income. There could also be changes in the status of issuers under applicable laws and regulations, including tax regulations, that may impact the regulatory or tax treatment of loaned securities and could, for example, result in a delay in the payment of dividend equivalent payments owed to a Fund (as permitted by applicable law).

II-12

Regulations adopted by global prudential regulators require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many securities lending agreements, terms that delay or restrict the rights of counterparties, such as the Fund, to terminate such agreements, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these requirements, as well as potential additional government regulation and other developments in the market, could adversely affect the Fund’s ability to terminate existing securities lending agreements or to realize amounts to be received under such agreements. Prudential regulation may also favor lenders that can provide additional protections, such as liens that are exercisable in connection with a lender default, to borrowers. Certain Funds expect to provide additional protections to borrowers, where permitted pursuant to a Fund’s investment policies and if BlackRock believes doing so is in the best interest of the Fund.

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 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 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, if required, 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

II-13

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 Prospectus. 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 397 days provided that the 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 397 days provided: (i) they are subject to a demand feature entitling the Fund to the payment of principal and interest within 397 days 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 397 days.

In determining a Fund’s weighted average portfolio maturity and whether a long-term variable rate demand instrument has a remaining maturity of 397 days 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 397 days 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.

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.

II-14

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.

Regulations adopted by global prudential regulators that are now in effect require certain bank-regulated counterparties and certain of their affiliates to include in certain financial contracts, including many agreements with respect to when-issued, TBA and forward commitment transactions, terms that delay or restrict the rights of counterparties, such as a Fund, to terminate such agreements, foreclose upon collateral, exercise other default rights or restrict transfers of credit support in the event that the counterparty and/or its affiliates are subject to certain types of resolution or insolvency proceedings. It is possible that these new requirements, as well as potential additional government regulation and other developments in the market, could adversely affect a Fund’s ability to terminate existing agreements with respect to these transactions or to realize amounts to be received under such agreements.

Diversification Status

Each Fund’s investments will be limited in order to allow the Fund to continue to qualify as a regulated investment company 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 regulated investment companies, 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 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 regulated investment companies) 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 “Information on Directors and Officers, ‘—Biographical Information,’ ‘— Share Ownership’ and ‘— Compensation of Directors’” or “Information on Trustees and Officers, ‘—Biographical Information,’ ‘— Share Ownership’ and ‘— Compensation of Trustees’,” as applicable, in Part I 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.

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 the fees paid by your Fund to the Manager for the Fund’s last three fiscal years or other applicable periods, see “Management, Advisory and Other Service Arrangements — Management Agreement” or “Management and Advisory Arrangements,” as applicable, in Part I 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.

II-15

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 NAV); 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 The Bank of New York Mellon (“BNYM”), State Street Bank and Trust Company (“State Street”) or JPMorgan Chase Bank, N.A. (“JPM”) pursuant to an agreement between BNYM, State Street or JPM, as applicable, 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 and/or Shareholder Servicing Plans.”

Organization of the Manager. The Manager, BlackRock Advisors, LLC, is a Delaware limited liability company and an indirect, majority-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 “Management, Advisory and Other Service Arrangements — Administration Agreement” or “Management and Advisory Arrangements,” as applicable, in Part I 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 with BlackRock 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 “Management, Advisory and Other Service Arrangements, ‘— Transfer Agent’ or ‘— Transfer Agency Agreement’” or “Management and Advisory Arrangements — Transfer Agency and Shareholders’ Administrative Services,” as applicable, in Part I of each Fund’s SAI.

II-16

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 are provided 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. A Fund also may use special purpose custodian banks from time to time for certain assets.

Accounting Services. Each Fund has entered into an agreement with BNYM, State Street or JPM, pursuant to which BNYM, State Street or JPM provides certain accounting and administrative services to the Fund. Each Fund pays a fee for these services.

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

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 Agreements”). The Distribution Agreements obligate 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. Each Distribution Agreement is subject to the same renewal requirements and termination provisions as the Management Agreement described above. See “Information on Sales Charges and Distribution Related Expenses” or “Information on Distribution Related Expenses,” as applicable, in Part I of each Fund’s SAI for information on the fees paid by your Fund for the periods indicated.

Disclosure of Portfolio Holdings

The Board of Trustees of each Fund and the Board of Directors of the Manager have each approved Portfolio Holdings and Related Information Distribution Guidelines (the “Policy”) regarding the disclosure of each Fund’s portfolio securities, as applicable, and other portfolio information. The purpose of the Policy 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 earlier or more frequently than shareholders and prospective shareholders.

Pursuant to the Policy, each Fund and the Manager may, under certain circumstances as set forth below, make selective disclosure with respect to a Fund’s Portfolio Characteristics (as defined below) and Portfolio Holdings (as defined below). The Board of Trustees of each Fund and the Board of Directors of the Manager have each approved the adoption by the Fund of the Policy, and employees of the Manager are responsible for adherence to the Policy. The Board of Trustees provides ongoing oversight of the Fund’s and Manager’s compliance with the Policy.

Disclosure of material non-public information (“Confidential Information”) about a Fund’s Portfolio Holdings and/or Portfolio Characteristics is prohibited, except as provided in the Policy.

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 and confidentiality obligations are in effect, as appropriate.

II-17

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 SEC (e.g., a fund’s annual report and annual financial statements), 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.

Portfolio Holdings and Portfolio Characteristics may be disclosed in accordance with the below schedule or as specified in a Fund’s registration statement.

II-18

Open-End Mutual Funds (Excluding Money Market Funds)

II-19

Open-End Mutual Funds and ETFs (Excluding Money Market Mutual Funds and MM ETFs)

Money Market Mutual Funds and ETFs^3,4,5

Money Market ETFs will comply with the disclosure requirements under both the Money Market (Rule 2a-7) Policy and the ETF Rule (Rule 6c-11) Policy.

II-20

Guidelines for Confidential and Non-Material Information. Confidential Information may be disclosed to the Fund’s Board of Trustees and its counsel, outside counsel for the Fund, the Fund’s auditors and to certain third-party service providers (e.g., Fund administrator, Fund custodian, proxy voting service), securities lending borrowers, and broker-dealers that are fund counterparties. Non-disclosure or confidentiality agreements will be in place with such service providers, borrowers, and broker-dealers. With respect to Confidential Information, the Fund’s CCO or his or her designee may authorize the following, subject in the case of (ii) and (iii) to a confidentiality or non-disclosure arrangement:

(i) the preparation and posting of the Fund’s Portfolio Holdings and/or Portfolio Characteristics to its website on a more frequent basis than authorized above;

(ii) the disclosure of the Fund’s Portfolio Holdings to third-party service providers not noted above; and

(iii) the disclosure of the Fund’s Portfolio Holdings and/or Portfolio Characteristics to other parties for legitimate business purposes.

II-21

Fact Sheets and Reports

Other Information. The Policy shall also apply to other Confidential Information of a Fund such as performance attribution analyses or security-specific information (e.g., information about Fund holdings where an issuer has been downgraded, been acquired or declared bankruptcy).

Data on NAVs, asset levels (by total Fund and share class), accruals, yields, capital gains, dividends and fund returns (net of fees by share class) are generally available to shareholders, prospective shareholders, consultants, and third-party data providers upon request, as soon as such data is available.

Contact Information. For information about portfolio holdings and characteristics, BlackRock fund shareholders and prospective investors should call the number set out on the back cover of the Prospectus.

Compensation. Neither a Fund, a service provider nor any of their affiliated persons (as that term is defined in the Investment Company Act) shall receive compensation in any form in connection with the disclosure of information about such Fund’s Portfolio Holdings or Portfolio Characteristics.

Ongoing Arrangements. The Manager has entered into ongoing agreements to provide selective disclosure of Fund Portfolio Holdings to the following persons or entities:

With respect to each such arrangement, a Fund has a legitimate business purpose for the release of information. The release of the information is subject to confidential treatment to prohibit the entity from sharing with an unauthorized source or trading upon the information provided. The Funds, BlackRock and their affiliates do not receive any compensation or other consideration in connection with such arrangements.

The Funds and the Manager monitor, to the extent possible, the use of Confidential Information by the individuals or firms to which it has been disclosed. To do so, in addition to the requirements of any applicable confidentiality agreement and/or the terms and conditions of the Fund’s and Manager’s Codes of Ethics — all of which require persons or entities in possession of Confidential Information to keep such information confidential and not to trade on such information for their own benefit — the

II-22

Manager’s compliance personnel under the supervision of the Fund’s CCO, monitor the Manager’s securities trading desks to determine whether individuals or firms who have received Confidential Information have made any trades on the basis of that information. In addition, the Manager maintains an internal restricted list to prevent trading by the personnel of the Manager or its affiliates in securities — including securities held by a Fund — about which the Manager has Confidential Information. There can be no assurance, however, that the Fund’s policies and procedures with respect to the selective disclosure of Portfolio Holdings will prevent the misuse of such information by individuals or firms that receive such information.

Potential Conflicts of Interest

Certain activities of BlackRock, Inc., BlackRock Advisors, LLC, BlackRock Fund Advisors and the other subsidiaries of BlackRock, Inc. (collectively referred to in this section as “BlackRock”) and their respective directors, officers or employees, with respect to the Funds and/or other accounts managed by BlackRock, 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. BlackRock, its subsidiaries and their respective directors, officers and employees, including the business units or 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 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 may 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 identical or similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. Such other funds or accounts may offer exposure to strategies that are identical or substantially similar to those of a Fund but with different fees and expenses, governance and structures, and/or services provided by BlackRock. BlackRock is also a major participant 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, BlackRock is 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.

In addition, the portfolio holdings of certain BlackRock-advised investment vehicles managed in an identical or substantially similar manner as certain Funds are made publicly available on a more timely basis than the applicable Fund. In some cases, such portfolio holdings are made publicly available on a daily basis. While not expected, it is possible that a recipient of portfolio holdings information for such an investment vehicle could cause harm to a Fund that is managed in an identical or substantially similar manner, including by trading ahead of or against such Fund based on the information received.

When BlackRock seeks to purchase or sell the same assets for client accounts, including a Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in its 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 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 with respect to BlackRock-advised accounts 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 implements 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 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

II-23

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. 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) BlackRock or its 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) BlackRock or its other accounts or funds.

BlackRock, on behalf of other client accounts, on the one hand, and a Fund, on the other hand, may invest in or extend credit to different parts of the capital structure of a single issuer. BlackRock may pursue rights, provide advice or engage in other activities, or refrain from pursuing rights, providing advice or engaging in other activities, on behalf of other clients with respect to an issuer in which a Fund has invested, and such actions (or refraining from action) may have a material adverse effect on the Fund. In situations in which clients of BlackRock (including the Funds) hold positions in multiple parts of the capital structure of an issuer, BlackRock may not pursue certain actions or remedies that may be available to a Fund, as a result of legal and regulatory requirements or otherwise. BlackRock addresses these and other potential conflicts of interest based on the facts and circumstances of particular situations. For example, BlackRock may determine to rely on information barriers between different business units or portfolio management teams. BlackRock may also determine to rely on the actions of similarly situated holders of loans or securities rather than, or in connection with, taking such actions itself on behalf of the Funds.

In addition, to the extent permitted by applicable law, certain Funds may invest their assets in other funds advised by BlackRock, including funds that are managed by one or more of the same portfolio managers, which could result in conflicts of interest relating to asset allocation, timing of Fund purchases and redemptions, and increased remuneration and profitability for BlackRock and/or its personnel, including portfolio managers.

Third parties, including service providers to BlackRock or the Fund, may sponsor events (including, but not limited to, marketing and promotional activities and presentations, educational training programs and conferences) for registered representatives, other professionals and individual investors. There is a potential conflict of interest as such sponsorships may defray the costs of such activities to BlackRock, and may provide an incentive to BlackRock to retain such third parties to provide services to the Fund.

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. BlackRock may (but is not required to) effect purchases and sales between BlackRock clients (“cross trades”), including the Funds, if BlackRock believes 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 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 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 for its proprietary accounts or other accounts (including investment companies or collective investment vehicles) that it manages or advises. It is possible that one or more accounts managed or advised by BlackRock 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 proprietary or other accounts managed or advised by BlackRock achieve significant profits. 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 other accounts managed or advised by BlackRock, and/or the internal policies of BlackRock designed to comply with such requirements. As a result, there may be periods, for example, when BlackRock will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock is performing services or when position limits have been reached. For example, the investment activities of BlackRock for its proprietary accounts and accounts under its 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.

II-24

In connection with its management of a Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by BlackRock. 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, BlackRock will not have any obligation to make available any information regarding its 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, or the activities or strategies used for accounts managed by BlackRock 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 net asset value and liquidity of a Fund may be impacted by purchases and sales of the Fund by model-driven investment portfolios, as well as by BlackRock itself and by its advisory clients.

In addition, certain principals and certain employees of a Fund’s investment adviser are also principals or employees of other business units or entities within BlackRock. As a result, these principals and employees may have obligations to such other business units or entities or their clients and such obligations to other business units or entities or their 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, to the extent permitted by the Commission and applicable law, BlackRock, 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.

BlackRock may also create, write or issue derivatives for 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. Additionally, an affiliate of BlackRock will create, write or issue options, which may be based on the performance of certain Funds. BlackRock has entered into an arrangement with Markit Indices Limited, the index provider for underlying fixed-income indexes used by certain iShares ETFs, related to derivative fixed-income products that are based on such iShares ETFs. Trading activity in these derivative products could also potentially lead to greater liquidity for such products, increased purchase activity with respect to these iShares ETFs and increased assets under management for BlackRock.

A Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by BlackRock and may also enter into transactions with other clients of BlackRock where such other clients have interests adverse to those of the Fund. At times, these activities may cause business units or entities within BlackRock to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent such transactions are permitted, a Fund will deal with BlackRock on an arms-length basis.

To the extent authorized by applicable law, BlackRock 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 BlackRock will be in its view commercially reasonable, although BlackRock, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to BlackRock and such sales personnel, which may have an adverse effect on the Funds. Index based funds may use an index provider that is affiliated with another service provider of the Fund or BlackRock that acts as a broker, dealer, agent, lender or in other commercial capacities for a Fund or BlackRock.

Subject to applicable law, BlackRock (and its 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 BlackRock of any such fees or other amounts.

When BlackRock acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Funds, BlackRock 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. BlackRock will not have any obligation to allow its credit to be used in connection with a Fund’s establishment of its business

II-25

relationships, nor is it expected that the Fund’s counterparties will rely on the credit of BlackRock in evaluating the Fund’s creditworthiness.

BlackRock Investment Management, LLC (“BIM”) or BlackRock Institutional Trust Company, N.A. (“BTC”), as applicable, each an affiliate of BlackRock, pursuant to SEC exemptive relief, acts as securities lending agent to, and receives a share of securities lending revenues from, the Funds. BlackRock will also 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 securities lending agent may have an incentive to, among other things, 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 securities 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 the Funds and certain other clients and/or funds against a shortfall in collateral in the event of borrower default. On a regular basis, BlackRock calculates the potential dollar exposure of collateral shortfall resulting from a borrower default (“shortfall risk”) in the securities lending program. BlackRock establishes program-wide borrower limits (“credit limits”) to actively manage borrower-specific credit exposure. BlackRock oversees the risk model that calculates projected collateral shortfall values using loan-level factors such as loan and collateral type and market value as well as specific borrower credit characteristics. When necessary, BlackRock may adjust securities lending program attributes by restricting eligible collateral or reducing borrower credit limits. As a result, the management of program-wide exposure as well as BlackRock-specific indemnification exposure may affect the amount of securities lending activity BlackRock may conduct at any given point in time by reducing the volume of lending opportunities for certain loans (including by asset type, collateral type and/or revenue profile).

BlackRock may decline to make a securities loan on behalf of a Fund, discontinue lending on behalf of a Fund or terminate a securities loan on behalf of a Fund for any reason, including but not limited to regulatory requirements and/or market rules, liquidity considerations, or credit considerations, which may impact Funds by reducing or eliminating the volume of lending opportunities for certain types of loans, loans in particular markets, loans of particular securities or types of securities, or for loans overall. In addition, some borrowers may prefer certain BlackRock lenders that provide additional protections against lender default that are favored by their prudential regulation.

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 borrower 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.

Purchases and sales of securities and other assets for a Fund may be aggregated with orders for other BlackRock client accounts, including with accounts that pay different transaction costs solely due to the fact that they have different research payment arrangements. BlackRock, however, is not required to aggregate orders if portfolio management decisions for different accounts are made separately, or if they determine that 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 an aggregated order.

BlackRock, unless prohibited by applicable law, may cause a Fund or account to pay a broker or dealer a commission for effecting a transaction that exceeds the amount another broker or dealer would have charged for effecting the same transaction in recognition of the value of brokerage and research services provided by that broker or dealer. Under the European Union Markets in Financial Instruments Directive (Directive 2014/65/EU) and Markets in Financial Instruments Regulation (Regulation (EU) No

II-26

600/2014) (together “MiFID II”), European Union’s (the “EU”) investment managers, including BlackRock International Limited (“BIL”) which acts as a sub-adviser to certain Funds, pay for research from brokers and dealers directly out of their own resources, rather than through client commissions.

Subject to applicable law, BlackRock may select brokers that furnish BlackRock, the Funds, other BlackRock client accounts 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, unless prohibited by applicable law, 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, unless prohibited by applicable law, may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer 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 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 owns a minority interest in, and is a member of, Members Exchange (“MEMX”), a newly created U.S. stock exchange. Transactions for a Fund may be executed on MEMX if third party brokers select MEMX as the appropriate venue for execution of orders placed by BlackRock traders on behalf of client portfolios.

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, provided that 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 and/or its advisory clients (including other funds and separately managed accounts) 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 reserves the right, subject to compliance with applicable law, to redeem at any time some or all of the shares of a Fund acquired for its own accounts. A large redemption of shares of a Fund by BlackRock could significantly reduce the asset size

II-27

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 but is not obligated to do so and may elect not to do so.

It is possible that a Fund may invest in securities of, or engage in transactions with, companies in which BlackRock has significant debt or equity investments or other interests. A Fund may also invest in issuances (such as structured notes) by entities for which BlackRock provides and is compensated for cash management services relating to the proceeds from the sale of such issuances. In making investment decisions for a Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any unit of BlackRock, in the course of these activities. In addition, from time to time, the activities of BlackRock may limit a Fund’s flexibility in purchases and sales of securities. As indicated below, BlackRock may engage in transactions with companies in which BlackRock-advised funds or other clients of BlackRock have an investment.

BlackRock and its personnel and other financial service providers may have interests in promoting sales of the Funds. With respect to BlackRock and its 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 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 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 may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for such 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.

BlackRock and its 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 and employees 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 [email protected].

BlackRock 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 another Fund or 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 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 its advice in certain securities or instruments issued by or related to companies for which BlackRock is performing advisory or other services or has proprietary positions. For example, 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 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

II-28

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 advisory or risk management assignment by BlackRock, or where personnel of BlackRock are directors or officers of the issuer.

BlackRock has adopted and implemented policies and procedures that are designed to address potential conflicts that arise in connection with the advisory services BlackRock provides to Funds and other clients. Certain BlackRock advisory personnel may take views, and make decisions or recommendations, that are different than or opposite those of other BlackRock advisory personnel. Certain portfolio management teams within BlackRock may make decisions or take (or refrain from taking) actions with respect to clients they advise in a manner different than or adverse to the decisions made or the actions taken (or not taken) by the Funds’ portfolio management teams. The various portfolio management teams may not share information with each other, including as a result of certain information barriers and other policies, and will not have any obligation or other duty to do so.

BlackRock has established certain information barriers and other policies to address the sharing of information between different businesses within BlackRock, including with respect to personnel responsible with managing portfolios and voting proxies with respect to certain index equity portfolios versus those responsible for managing portfolios and voting proxies with respect to all other portfolios. As a result of information barriers, certain units of BlackRock generally will not have access, or will have limited access, to certain information and personnel, including senior personnel, in other units of BlackRock, and generally will not manage the Funds with the benefit of information possessed by such other units. Therefore, BlackRock may not be able to review potential investments for the Funds with the benefit of information held by certain areas of BlackRock.

BlackRock may determine to move certain personnel, businesses, or business units from one side of an information barrier to the other side of the information barrier. In connection therewith, BlackRock personnel, businesses, and business units that were moved will no longer have access to the information and personnel from the side of the information barrier from which they were moved. Information obtained in connection with such changes to information barriers may limit or restrict the ability of BlackRock to engage in or otherwise effect transactions on behalf of the Funds (including purchasing or selling securities that BlackRock may otherwise have purchased or sold for a client in the absence of a change to an information barrier). Information barriers may not have their intended impact due to, for example, changes in applicable law or inadvertent crossings of the barriers, and actions by personnel on one side of a barrier may impact the potential actions of personnel on the other side of a barrier.

Although the information barriers are intended to allow for independent portfolio management decision-making and proxy voting among certain BlackRock businesses, the investment activities of BlackRock for BlackRock clients, as well as BlackRock’s proprietary accounts, may nonetheless limit the investment strategies and rights of other clients (including the Fund). As BlackRock’s assets under management increases, BlackRock clients may face greater negative impacts due to ownership restrictions and limitations imposed by laws, regulations, rules, regulators, or issuers. For example, in certain circumstances where a BlackRock client invests in securities issued by companies that operate in certain industries (e.g., banking, insurance, and utilities) or in certain emerging or international markets, or are subject to regulatory or corporate ownership restrictions (e.g., with mechanisms such as poison pills in place to prevent takeovers), or where a BlackRock client invests in certain futures and derivatives, there may be limits on the aggregate amount invested by BlackRock for its clients and BlackRock’s proprietary accounts that may not be exceeded without the grant of a license or other regulatory or corporate approval, order, consent, relief, waiver or non-disapproval or, if exceeded, may cause BlackRock or its clients to be subject to enforcement actions, disgorgement of share ownership or profits, regulatory restrictions, complex compliance reporting, increased compliance costs or suffer disadvantages or business restrictions. In light of certain restrictions, BlackRock may also seek to make indirect investments (e.g., using derivatives) on behalf of its clients to receive exposure to certain securities in excess of the applicable ownership restrictions and limitations when legally permitted that will expose such clients to additional costs and additional risks, including any risks associated with investing in derivatives. There may be limited availability of derivatives that provide indirect exposure to an impacted security. BlackRock clients can be subject to more than one ownership limitation depending on each client’s holdings, and each ownership limitation can impact multiple securities held by the client. Certain clients or shareholders may have their own overlapping obligations to monitor their compliance with ownership limitations across their investments.

If certain aggregate ownership thresholds are reached either through the actions of BlackRock or a BlackRock client or as a result of corporate actions by the issuer, the ability of BlackRock on behalf of clients to purchase or dispose of investments, or exercise rights (including voting) or undertake business transactions, may be restricted by law, regulation, rule, or organizational documents or otherwise impaired. For example, to meet the requirements of an ownership limitation or restriction, a client may be unable to purchase or directly hold a security the client would otherwise purchase or hold. The limitation or restriction may be based on the holdings of other BlackRock clients instead of the specific client being restricted. For index funds, this means a fund

II-29

may not be able to track its index as closely as it would if it was not subject to an ownership limitation or restriction because the fund cannot acquire the amount of the impacted security included in its index. BlackRock on behalf of its clients may limit purchases, sell existing investments, utilize indirect investments, utilize information barriers, or otherwise restrict, forgo, or limit the exercise of rights (including transferring, outsourcing, or limiting voting rights or forgoing the right to receive dividends) 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. These types of restrictions could negatively impact a client’s performance or ability to meet its investment objective.

When BlackRock or a BlackRock client is subject to an ownership limitation, BlackRock may in its discretion seek permission from the applicable issuers or regulators to exceed the limitation. However, there is no guarantee that permission will be granted, or that, once granted, it will not be modified or revoked at a later date with minimal or no notice. The issuer and/or regulator may also require that BlackRock on behalf of itself and its clients take or refrain from taking certain actions in connection with the approval, order, consent, relief or non-disapproval, which BlackRock may accept if it believes the benefits outweigh the costs and may limit BlackRock from taking actions that it otherwise would take. In those circumstances where ownership thresholds or limitations must be observed, BlackRock seeks to allocate limited investment opportunities equitably among clients, taking into consideration benchmark weight and investment strategy. BlackRock may adopt certain controls designed to prevent the occurrence of a breach of any applicable ownership threshold or limits, including, for example, when ownership in certain securities nears an applicable threshold, BlackRock may limit additional purchases in such securities. If client 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 reduce these positions to meet the applicable limitations and BlackRock or such client may be subject to regulatory actions. In these cases, the investments will be sold in a manner that BlackRock deems fair and equitable over time.

Ownership limitations are highly complex. It is possible that, despite BlackRock’s intent to either comply with or be granted permission to exceed ownership limitations, it may inadvertently breach a limit or violate the corporate or regulatory approval, order, consent, relief or non-disapproval that was obtained.

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.

BlackRock may maintain securities indices. To the extent permitted by applicable laws, the Funds may seek to license and use such indices as part of their investment strategy. Index based funds that seek to track the performance of securities indices also may use the name of the index or index provider in the fund name. Index providers, including BlackRock (to the extent permitted by applicable law), may be paid licensing fees for use of their index or index name. In instances where BlackRock charges a unitary management fee, BlackRock may have a financial incentive to use a BlackRock index that is less costly to BlackRock than a third party index. BlackRock may benefit from the Funds using BlackRock indices by creating increasing acceptance in the marketplace for such indices. BlackRock is not obligated to license its indices to a Fund and the Funds are under no obligation to use BlackRock indices. Any Fund that enters into a license for a BlackRock index cannot be assured that the terms of any index licensing agreement with BlackRock will be as favorable as those terms offered to other licensees.

BlackRock may enter into contractual arrangements with third-party service providers to a Fund (e.g., custodians, administrators and index providers) pursuant to which BlackRock receives fee discounts or concessions in recognition of BlackRock’s overall relationship with such service providers. BlackRock may also enter into contractual arrangements with such service providers pursuant to which BlackRock incurs additional costs if the service provider’s services are terminated with respect to a Fund. To the extent that BlackRock is responsible for paying service providers out of its fees that it receives from the Funds, the benefits of lower fees, including any fee discounts or concessions, or any additional savings, may accrue, in whole or in part, to BlackRock, which could result in conflicts of interest relating to the use or termination of service providers to a Fund. In addition, conflicts of interest may arise with respect to contractual arrangements with third-party service providers to a Fund, or the selection of such providers, particularly in circumstances where BlackRock is negotiating on behalf of both funds that have a unitary management fee and those that do not or different service providers have different fee structures.

Conflicts of interest may arise as a result of simultaneous investment management of multiple client accounts by BlackRock’s investment professionals. For example, differences in the advisory fee structure may create the appearance of actual or potential conflicts of interest because such differences could create pecuniary incentives for BlackRock to favor one client account over another.

II-30

BlackRock owns or has 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 for the use of the systems. A Fund service provider’s payments to BlackRock for the use of these systems may enhance the profitability of BlackRock.

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

In recognition of a BlackRock client’s overall relationship with BlackRock, BlackRock may offer special pricing arrangements for certain services provided by BlackRock. Any such special pricing arrangements will not affect Fund fees and expenses applicable to such client’s investment in a Fund.

Present and future activities of BlackRock and its directors, officers and employees, 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 NAV next determined after a purchase order becomes effective. Each Fund attempts to maintain a NAV per share of $1.00. Share purchase orders are effective on the date Federal Funds become available to a Fund. Generally, if Federal Funds are available to a Fund prior to the determination of NAV 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 Distributor. The types of shareholder service programs offered to shareholders include: Fee-Based Programs; Automatic Investment Plan; and Systematic Withdrawal Plan.

Purchase of Shares of Summit Cash Reserves

Summit Cash Reserves 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 purchase or redemption order when an Authorized Person or, if applicable, such Authorized Person’s authorized designee, receives the order. Such customer orders will be priced at the Fund’s NAV 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 A and Investor C Shares

Purchase of Investor A 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-adviser, 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.

II-31

Purchases of Investor A Shares 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 Prospectus, 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 50 Hudson Yards, New York, New York 10001. Purchases may be effected on weekdays on which the NYSE is open for business (a “Business Day”). Payment for orders of Investor A Shares 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 Investor A 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.

Exchange Privilege. Unless an exemption applies, a front-end sales charge will be charged in connection with exchanges of Investor A Shares of the Fund for Investor A Shares of another fund advised by BlackRock or its affiliates that imposes such a sales charge. Exchanges of Investor C Shares of the Fund for Investor C Shares of one of the non-money market portfolios advised by BlackRock or its affiliates (each a “Non-Money Market Portfolio”) will be exercised at NAV. However, a contingent deferred sales charge (“CDSC”) will be charged in connection with the redemption of the Investor C Shares of the Non-Money Market Portfolio received in the exchange.

A CDSC of 1.00% may apply to certain redemptions of Investor C Shares of Summit Cash Reserves. The Investor C Shares CDSC is only charged upon redemptions of Investor C Shares within one year after you originally acquired the Investor C Shares of the Non-Money Market Portfolio, unless you qualify for a waiver. There is no CDSC charged on redemptions if you have owned your Investor C Shares for more than one year (as measured from your original purchase of Investor C Shares that you exchanged into Investor C Shares of Summit Cash Reserves). In determining whether an Investor C Shares CDSC is applicable to a redemption, the calculation will be determined in the manner that results in the lowest possible rate being charged. The charge will be assessed on an amount equal to the lesser of the proceeds of redemption or the cost of the shares being redeemed. Accordingly, no CDSC will be imposed on increases in NAV above the initial purchase price of Investor C Shares. In addition, no CDSC will be assessed on Investor C Shares acquired through reinvestment of dividends. It will be assumed that the redemption is first of shares held for over one year or shares acquired pursuant to reinvestment of dividends and then of shares held longest during the one-year period. A transfer of shares from a shareholder’s account to another account will be assumed to be made in the same order as a redemption.

See “Information on Sales Charges and Distribution Related Expenses” in Part I of the Fund’s SAI for information about amounts paid to the Distributor in connection with CDSC shares for the periods indicated.

The CDSC on Investor C Shares is not charged in connection with: (1) redemptions of Investor C Shares purchased through certain employer-sponsored retirement plans and fee-based programs previously approved by certain Funds and rollovers of current investments in the Fund through such plans; (2) exchanges pursuant to the exchange privilege described in the Fund’s Prospectus; (3) redemptions made in connection with minimum required distributions due to the shareholder reaching age 72 from IRA and 403(b)(7) accounts; (4) redemptions made with respect to certain retirement plans sponsored by BlackRock or its affiliates; (5) redemptions in connection with a shareholder’s death as long as the waiver request is made within one year of death or, if later, reasonably promptly following completion of probate (including in connection with the distribution of account assets to a beneficiary of the decedent) or disability (as defined in the Code) subsequent to the purchase of Investor C Shares; (6) withdrawals resulting from shareholder disability (as defined in the Code) as long as the disability arose subsequent to the purchase of the shares; (7) involuntary redemptions of Investor C Shares in accounts with low balances as described in “Redemption of Shares” below; (8) redemptions made pursuant to a systematic withdrawal plan, subject to the limitations set forth under “Systematic Withdrawal Plan” below; (9) redemptions related to the payment of BNY Mellon Investment Servicing Trust Company custodial IRA fees; and (10) redemptions when a shareholder can demonstrate hardship, in the absolute discretion of the Fund. In addition, no CDSC is charged on Investor C Shares acquired through the reinvestment of dividends or distributions.

Certain CDSC waivers and reductions on Investor C Shares may be available to customers of certain financial intermediaries, as described under “Intermediary-Defined Sales Charge Waiver Policies” in the Fund’s Prospectus. Please speak to your financial intermediary for more information.

II-32

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 534429, Pittsburgh, Pennsylvania 15253-4429. 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 in Rule 17Ad-15 under the Exchange Act. 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 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 Administrator and BRIL will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. The Fund, the Trust, the Administrator(s) 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 A Shares of the Fund. In addition, when Investor C Shares of the Fund are redeemed and the proceeds are used to purchase Investor C Shares of a Non-Money Market Portfolio, a CDSC will be imposed (unless an exemption applies) when the Investor C Shares of the Non-Money Market Portfolio are redeemed.

The Fund has adopted an automatic conversion feature for Investor C Shares. Effective November 23, 2020, Investor C Shares held for approximately eight years will be converted into Investor A Shares, as set forth in the Fund’s Prospectus. In addition, accounts that do not have a financial intermediary associated with them are not eligible to hold Investor C Shares, and any Investor C Shares held in such accounts will be automatically converted to Investor A Shares.

A CDSC of up to 1.00% may apply to certain redemptions of Investor A Shares of Summit Cash Reserves purchased in an exchange transaction for Investor A Shares of another mutual fund sponsored and advised by BlackRock or its affiliates (“BlackRock Fund”) where no initial sales charge was paid at the time of purchase of such fund (each, an “Investor A Load-Waived BlackRock Portfolio”) as part of an investment of $1,000,000 (lesser amounts may apply depending on the Investor A Load-Waived BlackRock Portfolio) or more. The Investor A Shares CDSC is only charged upon redemptions of Investor A Shares within 18 months after you originally acquired such Investor A Shares of the Investor A Load-Waived BlackRock Portfolio (a shorter holding period may apply depending on the Investor A Load-Waived BlackRock Portfolio), unless you qualify for a

II-33

waiver. There is no CDSC charged on redemptions if you have owned your Investor A Shares for more than 18 months (or for a shorter holding period, as applicable) as measured from your original purchase of Investor A Shares that you exchanged into Investor A Shares of Summit Cash Reserves or if you purchase Investor A Shares of Summit Cash Reserves not through an exchange. The deferred sales charge on Investor A Shares is not charged in connection with: (a) redemptions of Investor A Shares purchased through certain employer-sponsored retirement plans and rollovers of current investments in a Fund through such plans; (b) exchanges pursuant to the exchange privilege described in the Fund’s Prospectus; (c) redemptions made in connection with minimum required distributions due to the shareholder reaching age 72 from IRA and 403(b)(7) accounts; (d) redemptions made with respect to certain retirement plans sponsored by BlackRock or its affiliates; (e) redemptions (i) within one year of a shareholder’s death or, if later, the receipt of a certified probate settlement (including in connection with the distribution of account assets to a beneficiary of the decedent) or (ii) in connection with a shareholder’s disability (as defined in the Code) subsequent to the purchase of Investor A Shares; (f) involuntary redemptions of Investor A Shares in accounts with low balances; (g) certain redemptions made pursuant to the Systematic Withdrawal Plan (described below); (h) redemptions related to the payment of BNY Mellon Investment Servicing Trust Company custodial IRA fees; and (i) redemptions when a shareholder can demonstrate hardship, in the absolute discretion of a 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 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.

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 NAVs 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 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 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 Investor A Shares of the affiliated fund to be acquired.

Before effecting an exchange, shareholders of the Fund should obtain a currently effective prospectus of the affiliated 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 certain affiliated funds with shares for which certificates have not been issued may effect an exchange by wire through their securities dealers. 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 through the exchange privilege; however, the Fund reserves the right to limit the number of times an investor may effect an exchange. Certain 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 privilege is available only to U.S. shareholders in states where the exchange legally may be made.

An exchange pursuant to the exchange privilege 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.”

Additional Shareholder Features (Investor A and Investor C Shares Only)

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.

II-34

Systematic Withdrawal Plan (“SWP”). The Fund 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 is 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 “Account Services and Privileges — Automatic Investment Plan” in the Fund’s Prospectus) and the Systematic Withdrawal Plan at the same time.

Dividend Allocation Plan. The Dividend Allocation Plan allows shareholders to elect to have all their dividends and any other distributions from the Fund or any Eligible Fund (which includes the Fund and other funds as designated by BRIL from time to time) automatically invested at NAV 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.

Conversion of Investor C Shares to Investor A Shares

Effective November 23, 2020 (the “Effective Date”), approximately eight years after purchase, Investor C Shares of the Fund will convert automatically into Investor A Shares of the Fund (the “Investor C 8-Year Conversion”). It is the financial intermediary’s responsibility to ensure that the shareholder is credited with the proper holding period. As of the Effective Date, certain financial intermediaries, including group retirement recordkeeping platforms, may not have been tracking such holding periods and therefore may not be able to process such conversions. In such instances, Investor C Shares held as of the Effective Date will automatically convert to Investor A Shares approximately eight years after the Effective Date. If, as of November 23, 2028 (eight years after the Effective Date), a financial intermediary has not implemented systems or procedures to track holding periods commencing from the Effective Date, shareholders holding Investor C Shares through such financial intermediary will no longer be eligible to hold Investor C Shares and any such shares will convert to Investor A Shares as soon as reasonably practicable after such date.

In addition, accounts that do not have a financial intermediary associated with them are not eligible to hold Investor C Shares, and any Investor C Shares held in such accounts will be automatically converted into Investor A Shares (the “Investor C Direct Accounts Conversion” and together with the Investor C 8-Year Conversion, the “Investor C Conversions”).

The Investor C Conversions will occur at least once each month (on the “Investor C Conversion Date”) on the basis of the relative NAV of the shares of the two applicable classes on the Investor C Conversion Date, without the imposition of any sales load, fee or other charge. The Investor C Conversions will not be deemed a purchase or sale of the shares for Federal income tax purposes. Shares acquired through reinvestment of dividends on Investor C Shares will also convert automatically to Investor A Shares, as set forth in the Fund’s Prospectus. The Investor C Conversion Date for dividend reinvestment shares will be calculated taking into account the length of time the shares underlying the dividend reinvestment shares were outstanding.

Institutional Shares

Purchase of Shares. Summit Cash Reserves offers Institutional Shares as described in the Fund’s Prospectus.

In addition, the following investors may purchase Institutional Shares: employees, officers and directors/trustees of BlackRock, Inc., BlackRock Funds, Bank of America Corporation (“BofA Corp.”), Barclays PLC or their respective affiliates and immediate family members of such persons, if they open an account directly with BlackRock; individuals and “Institutional Investors” 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 (“Institutional Investors” include, but are not limited to, endowments, foundations, family offices, local, city, and state governmental institutions, corporations, and insurance company separate accounts); employer-sponsored retirement plans (which, for this purpose, do not include SEP IRAs, SIMPLE IRAs or SARSEPs), state sponsored 529 college savings plans, collective trust funds, investment companies or other pooled investment

II-35

vehicles, unaffiliated thrifts and unaffiliated banks and trust companies, 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; clients investing through a self-directed IRA brokerage account program sponsored by a retirement plan record-keeper, provided that such program offers only mutual fund options and that the program maintains an account with the Fund on an omnibus basis; clients of financial intermediaries that: (i) charge such clients 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; tax-qualified accounts for insurance agents that are registered representatives of an insurance company’s broker-dealer that has entered into an agreement with the Distributor to offer Institutional Shares, and the family members of such persons, with a minimum initial investment of $1,000; trust department clients of Bank of America, N.A. and its 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.

The Fund may in its discretion waive or modify any minimum investment amount, may reject any order for any class of shares and may suspend and resume the sale of shares of the Fund at any time.

Institutional Shares of the Fund may be purchased by customers of broker-dealers and agents that 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 time specified by the shareholder’s financial intermediary, but in no event later than the close of the federal funds wire (normally 6:45 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 CDSC and that shareholders meet eligibility requirements of the new share class.

DCC&S. Qualified Plans may be able to invest in shares of the Fund 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.

Purchase of Shares of WeLEAF

WeLEAF 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 purchase or redemption order when an Authorized Person or, if applicable, such Authorized Person’s authorized designee, receives the order. Such customer orders will be priced at the Fund’s NAV 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.

II-36

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-adviser, 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 Prospectus, 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 50 Hudson Yards, New York, New York 10001. Purchases may be effected on weekdays on which both the NYSE and the Federal Reserve Bank of Philadelphia are 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 WeLEAF for Investor A Shares of one of the funds advised by BlackRock or its affiliates where an initial sales charge is assessed at the time of purchase of such fund (each, an “Investor A Load BlackRock Fund”). Exchanges of Investor C Shares of WeLEAF for Investor C Shares of a Non-Money Market Portfolio will be exercised at NAV. However, a CDSC will be charged in connection with the redemption of the Investor C Shares of the Non-Money Market Portfolio received in the exchange.

A CDSC of up to 1.00% may apply to certain redemptions of Investor A Shares of WeLEAF purchased in an exchange transaction for Investor A Shares of a portfolio advised by BlackRock or its affiliates where no initial sales charge was paid at the time of purchase of such Fund (an “Investor A Load-Waived BlackRock Fund”) as part of an investment of $1,000,000 (lesser amounts may apply depending on the Investor A Load-Waived BlackRock Fund) or more. The Investor A Shares CDSC is only charged upon redemptions of Investor A Shares within 18 months after you originally acquired such Investor A Shares of the Investor A Load-Waived BlackRock Fund (a shorter holding period may apply depending on the Investor A Load-Waived BlackRock Fund), unless you qualify for a waiver. There is no CDSC charged on redemptions if you have owned your Investor A Shares for more than 18 months (or for a shorter holding period, as applicable) as measured from your original purchase of Investor A Shares that you exchanged into Investor A Shares of WeLEAF. The deferred sales charge on Investor A Shares is not charged in connection with: (a) redemptions of Investor A Shares purchased through certain employer-sponsored retirement plans and rollovers of current investments in a Fund through such plans; (b) exchanges pursuant to the exchange privilege described in the Fund’s Prospectus; (c) redemptions made in connection with minimum required distributions due to the shareholder reaching age 72 from IRA and 403(b)(7) accounts; (d) redemptions made with respect to certain retirement plans sponsored by BlackRock or its affiliates; (e) redemptions (i) within one year of a shareholder’s death or, if later, the receipt of a certified probate settlement (including in connection with the distribution of account assets to a beneficiary of the decedent) or (ii) in connection with a shareholder’s disability (as defined in the Code) subsequent to the purchase of Investor A Shares; (f) involuntary redemptions of Investor A Shares in accounts with low balances; (g) certain redemptions made pursuant to the Systematic Withdrawal Plan (described below); (h) redemptions related to the payment of BNY Mellon Investment Servicing Trust Company custodial IRA fees; and (i) redemptions when a shareholder can demonstrate hardship, in the absolute discretion of a Fund.

A CDSC of 1.00% may apply to certain redemptions of Investor C Shares of WeLEAF. The Investor C Shares CDSC is only charged upon redemptions of Investor C Shares within one year after you originally acquired the Investor C Shares of the Non-Money Market Portfolio, unless you qualify for a waiver. There is no CDSC charged on redemptions if you have owned your

II-37

Investor C Shares for more than one year (as measured from your original purchase of Investor C Shares that you exchanged into Investor C Shares of WeLEAF). In determining whether an Investor C Shares CDSC is applicable to a redemption, the calculation will be determined in the manner that results in the lowest possible rate being charged. The charge will be assessed on an amount equal to the lesser of the proceeds of redemption or the cost of the shares being redeemed. Accordingly, no CDSC will be imposed on increases in NAV above the initial purchase price of Investor C Shares. In addition, no CDSC will be assessed on Investor C Shares acquired through reinvestment of dividends. It will be assumed that the redemption is first of shares held for over one year or shares acquired pursuant to reinvestment of dividends and then of shares held longest during the one-year period. A transfer of shares from a shareholder’s account to another account will be assumed to be made in the same order as a redemption.

See “Information on Sales Charges and Distribution Related Expenses” in Part I of the Fund’s SAI for information about amounts paid to the Distributor in connection with CDSC shares for the periods indicated.

The CDSC on Investor C Shares is not charged in connection with: (1) redemptions of Investor C Shares purchased through certain employer-sponsored retirement plans and fee-based programs previously approved by certain Funds and rollovers of current investments in the Fund through such plans; (2) exchanges pursuant to the exchange privilege described in the Fund’s Prospectus; (3) redemptions made in connection with minimum required distributions due to the shareholder reaching age 72 from IRA and 403(b)(7) accounts; (4) redemptions made with respect to certain retirement plans sponsored by BlackRock or its affiliates; (5) redemptions in connection with a shareholder’s death as long as the waiver request is made within one year of death or, if later, reasonably promptly following completion of probate (including in connection with the distribution of account assets to a beneficiary of the decedent) or disability (as defined in the Code) subsequent to the purchase of Investor C Shares; (6) withdrawals resulting from shareholder disability (as defined in the Code) as long as the disability arose subsequent to the purchase of the shares; (7) involuntary redemptions of Investor C Shares in accounts with low balances as described in “Redemption of Shares” below; (8) redemptions made pursuant to a systematic withdrawal plan, subject to the limitations set forth under “Systematic Withdrawal Plan” below; (9) redemptions related to the payment of BNY Mellon Investment Servicing Trust Company custodial IRA fees; and (10) redemptions when a shareholder can demonstrate hardship, in the absolute discretion of the Fund. In addition, no CDSC is charged on Investor C Shares acquired through the reinvestment of dividends or distributions.

WeLEAF has adopted an automatic conversion feature for Investor C Shares. Effective November 23, 2020, Investor C Shares held for approximately eight years will be converted into Investor A Shares, as set forth in the Fund’s Prospectus. In addition, accounts that do not have a financial intermediary associated with them are not eligible to hold Investor C Shares, and any Investor C Shares held in such accounts will be automatically converted to Investor A Shares.

Certain CDSC waivers and reductions on Investor C Shares may be available to customers of certain financial intermediaries, as described under “Intermediary-Defined Sales Charge Waiver Policies” in the Fund’s Prospectus. Please speak to your financial intermediary for more information.

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 534429, Pittsburgh, Pennsylvania 15253-4429. 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. 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 exchange is a taxable event and,

II-38

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 Administrator and BRIL will employ reasonable procedures to confirm that instructions communicated by telephone are genuine. The Fund, the Trust, the Administrator 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 an Investor A Load BlackRock Fund with the proceeds of a redemption of Investor Shares of WeLEAF. In addition, when Investor Shares of WeLEAF are redeemed and the proceeds are used to purchase Investor C Shares of a Non-Money Market Portfolio, a CDSC will be imposed (unless an exemption applies) when the Investor C Shares of the Non-Money Market Portfolio are redeemed.

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.

Systematic Withdrawal Plan (“SWP”). WeLEAF 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 is 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 “Account Services and Privileges — Automatic Investment Plan” in the Fund’s Prospectus) and the Systematic Withdrawal Plan at the same time.

Dividend Allocation Plan. The Dividend Allocation Plan allows shareholders to elect to have all their dividends and any other distributions from WeLEAF or any Eligible Fund (which includes the Fund and other funds as designated by BRIL from time to time) automatically invested at NAV 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.

Conversion of Investor C Shares to Investor A Shares. Effective November 23, 2020 (the “Effective Date”), approximately eight years after purchase, Investor C Shares of WeLEAF will convert automatically into Investor A Shares of WeLEAF (the “Investor C 8-Year Conversion”). It is the financial intermediary’s responsibility to ensure that the shareholder is credited with the proper holding period. As of the Effective Date, certain financial intermediaries, including group retirement recordkeeping platforms, may not have been tracking such holding periods and therefore may not be able to process such conversions. In such instances, Investor C Shares held as of the Effective Date will automatically convert to Investor A Shares approximately eight years after the Effective Date. If, as of November 23, 2028 (eight years after the Effective Date), a financial intermediary has not implemented systems or procedures to track holding periods commencing from the Effective Date, shareholders holding Investor C Shares

II-39

through such financial intermediary will no longer be eligible to hold Investor C Shares and any such shares will convert to Investor A Shares as soon as reasonably practicable after such date.

In addition, accounts that do not have a financial intermediary associated with them are not eligible to hold Investor C Shares, and any Investor C Shares held in such accounts will be automatically converted into Investor A Shares (the “Investor C Direct Accounts Conversion” and together with the Investor C 8-Year Conversion, the “Investor C Conversions”).

The Investor C Conversions will occur at least once each month (on the “Investor C Conversion Date”) on the basis of the relative NAV of the shares of the two applicable classes on the Investor C Conversion Date, without the imposition of any sales load, fee or other charge. The Investor C Conversions will not be deemed a purchase or sale of the shares for U.S. federal income tax purposes. Shares acquired through reinvestment of dividends on Investor C Shares will also convert automatically to Investor A Shares, as set forth in WeLEAF’s Prospectus. The Investor C Conversion Date for dividend reinvestment shares will be calculated taking into account the length of time the shares underlying the dividend reinvestment shares were outstanding.

Institutional Shares

Purchase of Shares. WeLEAF offers Institutional Shares as described in the Fund’s Prospectus.

The following investors may purchase Institutional Shares of WeLEAF, provided that the beneficial owners of such shares are natural persons: employees, officers and directors/trustees of BlackRock, Inc., BlackRock Funds, BofA Corp., 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; clients investing through a self-directed IRA brokerage account program sponsored by a retirement plan record-keeper, provided that such program offers only mutual fund options and that the program maintains an account with the Fund on an omnibus basis; clients of financial intermediaries that: (i) charge such clients 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; tax-qualified accounts for insurance agents that are registered representatives of an insurance company’s broker-dealer that has entered into an agreement with the Distributor to offer Institutional Shares, and the family members of such persons, with a minimum initial investment of $1,000; trust department clients of Bank of America, N.A. and its 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.

The Fund may in its discretion waive or modify any minimum investment amount, may reject any order for any class of shares and may suspend and resume the sale of shares of the Fund at any time.

Institutional Shares of the Fund may be purchased by customers of broker-dealers and agents that 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 6:45 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.

II-40

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 CDSC and that shareholders meet eligibility requirements of the new share class.

Premier Shares

Purchase of Shares. WeLEAF offers Premier Shares as described in the Fund’s Prospectus.

The Fund may in its discretion waive or modify any minimum investment amount, may reject any order for any class of shares and may suspend and resume the sale of shares of the Fund at any time.

Premier Shares of the Fund may be purchased by customers of broker-dealers and agents that 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.

Only purchase orders submitted through the NSCC Fund/SERV trading platform will be accepted. Payment may, in the discretion of the Fund, be made in the form of securities that are permissible investments for 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 CDSC and that shareholders meet eligibility requirements of the new share class. Please speak to your financial intermediary for information about specific policies and procedures applicable to your account.

The Fund’s initial investment minimum is described in the Prospectus. There are no subsequent investment minimums. The Fund reserves the right to reduce or waive the minimums in certain cases.

II-41

Purchase of Shares of Circle Reserve

Institutional Shares

Purchase of Shares. Circle Reserve offers Institutional Shares as described in the Fund’s Prospectus. The minimum investment for the initial purchase of shares is $2 billion. Shares are only available for purchase by Circle Internet Financial, LLC and Circle Internet Financial Europe SAS.

The Fund may in its discretion waive or modify any minimum investment amount, may reject any order for any Institutional Shares and may suspend and resume the sale of shares of the Fund at any time.

Other Purchase Information. Shares of the Fund are sold on a continuous basis by BRIL as distributor. BRIL maintains its principal offices at 50 Hudson Yards, New York, New York 10001. Purchases may be effected on weekdays on which both the NYSE and the Federal Reserve Bank of Philadelphia are 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.

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 6:45 p.m. (Eastern time)). 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.

Right of Accumulation

Investors have a “right of accumulation” under which any of the following may be combined with the amount of the current purchase in determining whether an investor qualifies for a breakpoint and a reduced front-end sales charge: (i) the current value of an investor’s existing Investor A, Investor A1, Investor C, Investor P, Institutional, Class K and Premier Shares in most BlackRock Funds, (ii) the current value of an investor’s existing shares of certain unlisted closed-end management investment companies sponsored and advised by BlackRock or its affiliates and (iii) the investment in the BlackRock CollegeAdvantage 529 Program by the investor or by or on behalf of the investor’s spouse and children. Financial intermediaries may value current holdings of their customers differently for purposes of determining whether an investor qualifies for a breakpoint and a reduced front-end sales charge, although customers of the same financial intermediary will be treated similarly. In order to use this right, the investor must alert BlackRock to the existence of any previously purchased shares. Although Investor A Shares of WeLEAF and Summit Cash Reserves generally are not subject to a sales charge, an investor’s existing Investor A, Investor C, Institutional and Premier Shares in WeLEAF and Summit Cash Reserves, as applicable, may be combined with the amount of an investor’s current purchase in determining whether an investor qualifies for a breakpoint and a reduced front-end sales charge. Institutional Shares of Circle Reserve may not be combined with shares of any other BlackRock Funds for purposes of determining whether an investor qualifies for a breakpoint and a reduced front-end sales charge.

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 50 Hudson Yards, New York, NY 10001. The Distributor is an affiliate of BlackRock.

Each Fund (with the exception of Circle Reserve, BlackRock Government Money Market Portfolio and BlackRock Government Money Market V.I. Fund) has adopted a shareholder servicing plan and/or a distribution plan or plans (in the case of Summit Cash Reserves with respect to Investor C Shares only and in the case of WeLEAF with respect to Investor A, Investor C and Service Shares only) (each, a “Distribution Plan”) in compliance with Rule 12b-1 under the Investment Company Act. Each Fund is authorized to pay the Distributor a fee at an annual rate based on the average daily NAV of Fund accounts maintained through the Distributor. 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

II-42

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 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.

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. 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. Sales personnel may receive different compensation for selling different classes of shares.

See “Information on Sales Charges and Distribution Related Expenses” or “Information on Distribution Related Expenses,” as applicable, in Part I 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 Financial Industry Regulatory Authority (“FINRA”) imposes a limitation on certain asset-based sales charges. The maximum sales charge rule is applied separately to each class and limits the aggregate of distribution fee payments and CDSCs 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).

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, BRIL 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, for services to a Fund and its shareholders and/or for data provision or technology support. A Service Organization may perform these obligations itself or may arrange for a third party to perform them. BlackRock may also make payments to Service Organizations as part of an effort to enhance its

II-43

business relationship with such entities trading on technology platforms. 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 Prospectus 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 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.

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.

II-44

C. Data Provision and Technology Support

BlackRock may make Additional Payments to Service Organizations for the provision of certain analytical or other data services relating to the Funds, such as statistical information regarding sales of the Funds, or technology support. Such Additional Payments are generally made as a fixed dollar amount, and not based on assets or sales.

D. 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.

II-45

II-46

E. Sponsorship and Other Incentive Payments and Services

In addition to the Additional Payments described above, BlackRock 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 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 their affiliates, or to a third party vendor, and may vary depending upon the

II-47

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 has 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 ETFs and other exchange-traded products.

F. Conflicts

Additional Payments made by BlackRock to a Service Organization or its affiliates 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 or its affiliates 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 and other assets selected from the Fund’s portfolio holdings at its discretion. In-kind payment means payment will be made in portfolio securities and other assets rather than cash. If this occurs, the redeeming shareholder might incur brokerage or other transaction costs to convert the securities and other assets to cash. In an in-kind redemption, a pro rata portion of a Fund’s portfolio holdings will generally be distributed to the redeeming shareholder. 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 NAV during any 90-day period for any shareholder of the Fund. The redemption price is the NAV 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. The redemption price will be reduced by any applicable CDSC.

If notice is received by the Fund’s transfer agent or certain financial intermediaries, 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.

Summit Cash Reserves — Redemption of Shares

Redemptions may be made in the manner and amounts described in Summit Cash Reserves’ 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 Investment Servicing (US) Inc. 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 (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.

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.

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 NAV. 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 NAV during any 90-day period for any one shareholder of the Fund.

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 of portfolio securities is not reasonably practicable, or for such other periods as the SEC may permit. (The Fund 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.

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.

Service Shares

Redemption of Shares. WeLEAF 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 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 NAV. 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 NAV during any 90-day period for any one shareholder of the Fund.

II-51

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 practicable, or for such other periods as the SEC may permit. (The Fund 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.

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.

DETERMINATION OF NET ASSET VALUE

Each Fund seeks to maintain a NAV 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 NAV of $1.00 per share for each Fund; however, there can be no assurance that a constant NAV will be maintained for any Fund. Such procedures include a review of the extent of any deviation of NAV per share, based on available market quotations, from the $1.00 amortized cost per share.

Should that deviation exceed ¹⁄₂ 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 NAV 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 to be “eligible securities” under Rule 2a-7 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

II-52

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.

See “Yield Information” in Part I 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, or (4) the yield on an investment in 90-day Treasury bills on a rolling basis, assuming quarterly compounding. 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.

II-53

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 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 Fund”) intends to purchase only securities with remaining maturities of 397 days or less as determined in accordance with the rules of the Commission. As a result, the portfolio turnover rates of a Money Market Fund will be relatively high. However, because brokerage commissions will not normally be paid with respect to investments made by a Money Market Fund, the turnover rates should not adversely affect the Fund’s NAVs 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 offered securities are purchased or sold directly from or to an issuer, no commissions or discounts are paid except where required by local markets.

The Manager or sub-advisers 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 or sub-advisers 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 “Portfolio Transactions” or “Portfolio Transactions and Brokerage,” as applicable, in Part I 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.

II-54

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, 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 “Portfolio Transactions” or “Portfolio Transactions and Brokerage,” as applicable, in Part I 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 NAV. Except as otherwise provided in a Fund’s Prospectus, shares purchased will begin accruing dividends on the day following the date of purchase. Until they are paid, dividends that are declared 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.

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.

Taxes

Each Fund intends to elect and to qualify or to continue to qualify, as appropriate, for the special tax treatment afforded regulated investment companies 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 regulated investment company 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 regulated investment company 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 regulated investment companies. Losses in one series of a regulated investment company do not offset gains in another, and the requirements (other than certain organizational requirements) for qualifying for regulated investment company 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 regulated investment company to pay a nondeductible 4% excise tax to the extent the regulated investment company does not distribute, during each calendar year, at least 98% of its ordinary income, determined on a calendar year basis,

II-55

and at least 98.2% of its capital gain net income, determined, in general, as if the regulated investment company’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 regulated investment company.

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 regulated investment company 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.

A shareholder in a money market fund (whether or not it has a floating NAV) may elect to adopt a simplified, aggregate accounting method under which gains and losses can be netted based on the shareholder’s taxable year rather than reported separately. Shareholders are urged to consult their tax advisors before deciding to adopt such accounting method.

If any Fund (other than a Fund that is a government money market fund) imposes a discretionary liquidity fee on share redemptions, 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 discretionary liquidity fee cannot be separately claimed as a deduction.

Any such discretionary liquidity fee will constitute an asset of the imposing Fund and will serve to benefit non-redeeming shareholders. If such fees were distributed to non-redeeming shareholders, the tax treatment would be similar to the tax treatment of distributions described in this section. Such fees may raise the Fund’s NAV, increasing the taxable income or reducing the deductible losses of shareholders that redeem their shares at a later time when such fees are not being charged. If a Fund receives discretionary liquidity fees, it will consider the appropriate tax treatment of such fees to the Fund at such time. However, due to a lack of guidance, the tax consequences of liquidity fees to the Fund and the shareholders is unclear and may differ from that described in this section.

Should a negative interest rate scenario ever occur that causes a government or retail money market fund to have a negative gross yield, the fund may account for the negative gross yield by either using a floating NAV or a reverse distribution mechanism that

II-56

seeks to maintain a stable NAV of the fund by cancelling shareholders’ shares in the amount of the negative gross yield. Under a reverse distribution mechanism, shareholders in a fund would observe a stable share price but a declining number of shares for their investment. After a cancellation of shares, 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. However, due to a lack of guidance regarding the cancellation of shares, the tax consequences of such cancellation of shares to the Fund and the shareholders is unclear and may differ from that described in this section.

Under certain provisions of the Code, some shareholders may be subject to a 24% 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 regulated investment company 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.

No gain or loss will be recognized by Investor C shareholders on the conversion to Investor A Shares. A shareholder’s tax basis in the Investor A Shares acquired upon conversion will be the same as the shareholder’s tax basis in the converted Investor C Shares and the holding period of the acquired Investor A Shares will include the holding period for the converted Investor C Shares.

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 regulated investment company 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 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.

II-57

Separately, a 30% withholding tax is currently imposed on U.S. source dividends, interest and other income items paid 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 regulated investment companies 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.

PROXY VOTING POLICIES AND PROCEDURES

The Board of Trustees of the Funds has delegated the voting of proxies for the Funds’ securities to the Manager pursuant to the Open-End Active and Fixed Income Index Fund Proxy Voting Policy (the “Active Fund Proxy Voting Policy”).

With respect to the Funds, the Manager has adopted the BlackRock Active Investment Stewardship — Global Engagement and Voting Guidelines (the “BAIS Guidelines”).

If a Fund invests in an underlying fund managed by BlackRock, the Fund will use its proxy voting policy when voting on proxies for the underlying fund while the underlying fund will use its proxy voting policy when voting proxies on investments the underlying fund holds. Therefore, the Fund may use the Active Fund Proxy Voting Policy while an underlying fund may use the Index Equity Fund Proxy Voting Policy, and the opposite is also true.

Copies of the Active Fund Proxy Voting Policy and the BAIS Guidelines are attached as Appendix B to this SAI. Only those guidelines that are applicable to a particular Fund pursuant to the Active Fund Proxy Voting Policy are considered to form a part of the Fund’s SAI.

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/proxyrecords and (ii) on the Commission’s website at http://www.sec.gov.

GENERAL INFORMATION

Description of Shares

Shareholders of a Fund are entitled to one vote for each full share held and fractional votes for fractional shares held in the election of Trustees and generally on other matters submitted to the vote of shareholders of the Fund. Shareholders of a class that bears distribution and/or service expenses have exclusive voting rights with respect to matters relating to such distribution and service 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 the Trustees of a Fund, in which event the holders of the remaining shares would be unable to elect any person as a Trustee.

No Fund intends to hold annual meetings of shareholders in any year in which the Investment Company Act does not require shareholders to act upon any of the following matters: (i) election of Trustees; (ii) approval of a management agreement; (iii) approval of a distribution agreement; and (iv) ratification of selection of independent accountants. Shares issued are fully paid and non-assessable and have no preemptive rights. Redemption and conversion rights are discussed elsewhere herein and in each Fund’s Prospectus. Each share of each class of Common Stock is entitled to participate equally in dividends and distributions declared by a Fund and in the net assets of the Fund upon liquidation or dissolution after satisfaction of outstanding liabilities.

For Funds organized as Maryland corporations, the by-laws of the Fund require that a special meeting of shareholders be held upon the written request of a minimum percentage of the outstanding shares of the Fund entitled to vote at such meeting, if they comply with applicable Maryland law.

II-58

Certain of the Funds are organized as “Massachusetts business trusts.” Under Massachusetts law, shareholders of such a trust may, under certain circumstances, be held personally liable as partners for its obligations. However, the Declaration of Trust establishing a trust, a copy of which for each applicable Fund, together with all amendments thereto (the “Declaration of Trust”), is on file in the office of the Secretary of the Commonwealth of Massachusetts, contains an express disclaimer of shareholder liability for acts or obligations of the trust and provides for indemnification and reimbursement of expenses out of the trust property for any shareholder held personally liable for the obligations of the trust. The Declaration of Trust also provides that a trust may maintain appropriate insurance (for example, fidelity bond and errors and omissions insurance) for the protection of the trust, its shareholders, trustees, officers, employees and agents covering possible tort and other liabilities. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which both inadequate insurance existed and the trust itself was unable to meet its obligations.

Certain Funds are organized as Delaware statutory trusts.

Additional Information

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

II-59

APPENDIX A

Description of Bond Ratings

A rating is generally assigned to a fixed-income security at the time of issuance by a credit rating agency designated as a nationally recognized statistical rating organization (“NRSRO”) by the SEC. While NRSROs may from time to time revise such ratings, they undertake no obligation to do so, and the ratings given to securities at issuance do not necessarily represent ratings which would be given to these securities on a particular subsequent date.

NRSROs may rate specific investments (e.g., bonds), issuers (e.g., corporations, governments and financial institutions) and/or programs (e.g., commercial paper programs). However, certain types of investments may not be rated by NRSROs, such as certain government/sovereign obligations, US agency securities, commercial paper, time deposits at financial institutions, and derivative instruments such as credit default swaps. For these types of investments, as well as US Treasury securities (some of which are not rated), where a NRSRO has not rated the specific investment but has rated the investment’s issuer, program, financial institution or underlying reference asset, BlackRock Advisors, LLC, BlackRock Fund Advisors or their respective affiliates (“BlackRock”) may consider the investment to have the same NRSRO rating as its issuer, program, financial institution or underlying reference asset, as applicable. In the case of municipal securities, where one NRSRO provides multiple ratings for the same security (e.g., “underlying,” “insured” and/or “enhanced” ratings), BlackRock may consider the security to have the highest of the multiple ratings.

New issue securities (regardless of type) may not be rated by a NRSRO at the time of their initial offering. Preliminary prospectuses or term sheets for new issue securities may include an expected rating for the security (as determined by the underwriter and/or issuer) or a NRSRO rating for the issuer of the security. If applicable, when deciding whether to purchase a new issue security that has not yet been rated by a NRSRO, BlackRock may attribute an expected rating to the security based on: (i) the expected rating of the security set forth in the preliminary prospectus or term sheet for the security; (ii) the NRSRO’s rating for the issuer of the security set forth in the preliminary prospectus or term sheet for the security; or (iii) with respect to asset-backed securities, the rating of a prior issuance having a similar structure or the same sponsor.

Where the investment objective of a fund is to track the performance of an index that includes credit ratings eligibility criteria as part of its index methodology, the fund may purchase any security within the index, such security having been determined by the index provider as meeting its credit ratings eligibility criteria. The credit ratings practices of an index provider may differ from BlackRock’s practices, as described above. Further, the fund may invest, directly or indirectly, in securities that are not rated by a rating agency or securities with a credit rating that differs from the credit rating specified in its index methodology in various circumstances, including where a security is downgraded but not yet removed from an index, following the removal of a security from an index prior to its sale by the fund or as a result of a corporate action or restructuring affecting an issuer of a security held by the fund.

Fixed-income securities which are unrated may expose the investor to risks with respect to capacity to pay interest or repay principal which are similar to the risks of lower-rated speculative bonds. Evaluation of these securities is dependent on BlackRock’s judgment, analysis and experience in the evaluation of such securities.

Investors should note that the assignment of a rating to a security by an NRSRO may not reflect the effect of recent developments on the issuer’s ability to make interest and principal payments or on the likelihood of default.

Securities deemed to be high yield are rated below Baa3 by Moody’s and below BBB- by S&P Global Ratings and Fitch.

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. Moody’s defines credit risk as the risk that an entity may not meet its contractual financial obligations as they come due and any estimated financial loss in the event of default or impairment. The contractual financial obligations addressed by Moody’s ratings are those that call for, without regard to enforceability, the payment of an ascertainable amount, which may vary based upon standard sources of variation (e.g., floating interest rates), by an ascertainable date. Moody’s rating addresses the issuer’s ability to obtain cash sufficient to service the obligation, and its willingness to pay. Moody’s ratings do

not address non-standard sources of variation in the amount of the principal obligation (e.g., equity indexed), absent an express statement to the contrary in a press release accompanying an initial rating. 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 or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment. Short-term ratings are assigned for obligations with an original maturity of thirteen months or less and reflect both on the likelihood of a default or impairment on contractual financial obligations and the expected financial loss suffered in the event of default or impairment. Moody’s issues ratings at the issuer level and instrument level on both the long-term scale and the short-term scale. Typically, ratings are made publicly available although private and unpublished ratings may also be assigned.

Moody’s differentiates structured finance ratings from fundamental ratings (i.e., ratings on nonfinancial corporate, financial institution, and public sector entities) on the global long-term scale by adding (sf) to all structured finance ratings. The addition of (sf) to structured finance ratings should eliminate any presumption that such ratings and fundamental ratings at the same letter grade level will behave the same. The (sf) indicator for structured finance security ratings indicates that otherwise similarly rated structured finance and fundamental securities may have different risk characteristics. Through its current methodologies, however, Moody’s aspires to achieve broad expected equivalence in structured finance and fundamental rating performance when measured over a long period of time.
