PROPOSAL 1—ELECTION OF BOARD NOMINEES

The purpose of Proposal 1 is to elect Board Members for each Fund.

Nominees for each FundFund.. The Board of each Fund consists of ten Board Members, eight of whom are not “interested persons” of the Funds (as defined in the 1940 Act) (the “Independent Board Members”). The Funds divide their Board Members into three classes: Class I, Class II and Class III, and generally only one class of Board Members stands for election each year.

Under this classified board structure, generally only those Board Members in a single class may be replaced in any one year, and it would require a minimum of two years to change a majority of the Board and effect a change in control under normal circumstances.year. The Board believes that it is in the best interest of the Funds, asclosed-end, exchange traded investment companies subject to extensive regulation by the SEC,Securities and Exchange Commission (“SEC”), to continue to have a classified board structure. The Board believes that a classified board structure provides a Fund and its shareholders with important benefits. The Board believes that a classified board structure promotes continuity of experiences and an orderly succession of Board Members by ensuring that at any given time there are experienced board members serving on the Board who are familiar with such Fund, its business, operations and investment and compliance policies, and its relationships with its services providers. Specifically, the Board believes that a classified board structure: (a) creates a more experienced Board that is better able to identify and accomplish long-term objectives in supervising the management of the Funds; (b) enhances the independence of the Independent Board Members from management and from special interest groups by providing them with a three-year term of office, so they are better positioned to make decisions that are in the best long-term interest of the Funds and their shareholders; (c) strengthens the Funds’ ability to attract and retain qualified individuals who are willing to make multi-year commitments to the Funds and to develop a deep understanding of the Funds; (d) allows new Board Members an opportunity to gain knowledge from experienced Board Members; (e) helps prevent complete changes in control and corresponding changes in fund philosophy or strategies in any one year; and (f) protects against abrupt changes in a Fund based on the short-term objectives of shareholders who may seek to implement an agenda that is contrary to the long-term interest of Fund shareholders.

The Board further believes that the considerations with respect to classified boards in theclosed-end, exchange traded investment company context are different than those for traditional operating companies, and in this regard notes that the classified board structure is expressly acknowledged by the 1940 Act, the principal regulatory regime governing the Funds and their operations. The role of a board of aclosed-end, exchange traded investment company is different in material respects to the role of a board of directors of a traditional operating company. For example, an investment company’s board has the primary responsibility for oversight of the fund’s service providers and management of conflicts of interest involving the fund, including oversight of the fund’s investment advisory arrangements. A traditional operating company does not have investment advisers and is not subject to the same types of conflicts of interests that an investment company’s board must oversee. Additionally, an investment company registered pursuant to the 1940 Act is subject to extensive regulation with respect to governance and operations that requires independence of its board members and makes them accountable to shareholders. In contrast, operating companies are not subject to these board independence requirements. Accordingly, theThe Board believes that a classified board structure is consistent with good corporate governance, which depends principally on active and independent board members who have extensive business experience and are knowledgeable about critical aspects of the Fund.Funds. The BTZ Board considered the 2019non-binding shareholder proposal for such Board to consider declassification, but determined that such action would not be in the best interest of the Fund for

the reasons discussed herein. The BTZ Board further notes that BTZ’s market price ranks in the first quartile amongst its peers over the pastone-, three- and five-year periods.¹

The Class III Board Members are standing for election this year. The Class III Board Nominees for BGIO, HYT, DSU, CII, EGF, FRA, BSTZ and FRABMEZ are Cynthia L. Egan, Michael J. Castellano and Catherine A. Lynch. For each other Fund, the Class I Board Nominees are Michael J. Castellano, R. Glenn Hubbard, W. Carl Kester and John M. Perlowski. For

each other Fund, the Class II Board Nominees are Frank J. Fabozzi, Catherine A. Lynch and Karen P. Robards. Each Class III Board Member elected at the meeting will serve until the later of the date of the 20212023 annual meeting or until his or her successor is elected and qualifies, or until his or her earlier death, resignation, retirement or removal.

With respect to the Preferred Funds, the owners of Preferred Shares are entitled to vote as a separate class to elect two of the Board Members (the “Preferred Shares Nominees”) for the Preferred Fund in which they own Preferred Shares. This means that owners of Common Shares are not entitled to vote in connection with the election of the Preferred Shares Nominees. However, the owners of Common Shares and the owners of Preferred Shares, voting together as a single class, are entitled to elect the remainder of the Board Nominees. Frank J. Fabozzi and W. Carl Kester are currently the Board Members elected solely by the owners of Preferred Shares. Only Frank J. FabozziW. Carl Kester is standing for election this year as a Preferred Shares Nominee. W. Carl Kester’sFrank J. Fabozzi’s term as a Board Member of the Preferred Funds is scheduled to expire in 2020.2021. Therefore, he is not standing for election this year as a Preferred Shares Nominee.

Effective February 16, 2018, the Board of each Fund appointed Robert Fairbairn as a Class III Board Member of each Fund to fill the vacancy created by the resignation of a Class III Board Member. The Board has determined that it is desirable for Mr. Fairbairn to stand for election this year to serve out the term of the vacancy to which he was appointed. If Mr. Fairbairn is elected at the meeting, he will serve as a Class III Board Member until the later date of the 2019 annual meeting (when all of the Class III Board Members stand for election) or until his successor is elected and qualifies, or until his death, resignation, retirement or removal.

With respect to BGIO, HYT, DSU, CII, EGF, FRA, BSTZ and FRA,BMEZ, the Board recommends a vote“FOR” the election of Robert Fairbairn, R. Glenn Hubbard, W. Carl KesterCynthia L. Egan, Michael J. Castellano and John M. Perlowski.Catherine A. Lynch. With respect to all of the other Funds, the Board recommends a vote“FOR” the election of FrankMichael J. Fabozzi, Robert Fairbairn, Catherine A. LynchCastellano, R. Glenn Hubbard, W. Carl Kester and Karen P. Robards.John M. Perlowski. The aforementioned nominees to the Board of each Fund are collectively referred to herein as the “Board Nominees.” To vote for the Board Nominees, please vote by telephone or via the Internet, as described in the proxy card, or date and sign the enclosed proxy card and return it promptly in the enclosed postage-paid envelope. Each of the Board Nominees has consented to being named in this Proxy Statement and to serve as a Board Member if elected.

Please refer to the below table which identifies the Board Nominees and any Preferred Shares Nominees for election to the Board of each Fund and sets forth certain biographical information about the Board Members, including the Board Nominees, for all of the Funds.

Board Leadership Structure and Oversight

The Boards consist of ten Board Members, eight of whom are Independent Board Members. The registered investment companies registered under the 1940 Act that are advised by the Advisor are composed of theClosed-End BlackRock Fixed-Income Complex, two complexes ofopen-end fundsthe BlackRock Multi-Asset Complex and one complex of exchange-traded funds. The Funds are included in theClosed-End BlackRock Fixed-Income Complex. The Board Members also oversee the operations of the otheropen-end andclosed-end registered investment companies registered under the 1940 Act that are included in theClosed-End BlackRock Fixed-Income Complex as directors or trustees.

The Boards have overall responsibility for the oversight of the Funds. The ChairCo-Chairs of the Boards and the Chief Executive Officer are two different people. Not only is the Chair of the BoardseachCo-Chair an Independent Board Member, but also the Chair of each Board committee (each, a “Committee”) is also an Independent Board Member. The Boards have five standing Committees: an Audit Committee, a Governance Committee, a Compliance Committee, a Performance Oversight Committee and an Executive Committee. The Boards have also established an ad hoc DiscountSub-Committee.

The Boards currently oversee the Funds’ usage of leverage, including the Funds’ incurrence, refinancing and maintenance of leverage and, to the extent necessary or appropriate, authorize or approve the execution of documentation in respect thereto. The Executive Committee of each Fund has authority to make any such authorizations or approvals that are required between regular meetings of the Boards.

The Funds do not have a compensation committee because their executive officers, other than the Funds’ Chief Compliance Officer (“CCO”), do not receive any direct compensation from the Funds and the CCO’s compensation is comprehensively reviewed by the Boards. The role of the ChaireachCo-Chair of the Boards is to preside over all meetings of the Boards and to act as a liaison with service providers, officers, attorneys, and other Board Members between meetings. The Chair of each Committee performs a similar role with respect to such Committee. The ChairCo-Chairs of the Boards or CommitteesChair of a Committee may also perform such other functions as may be delegated by the Boards or the Committees from time to time. The Independent Board Members meet regularly outside the presence of the Funds’ management, in executive sessions or with other service providers to the

Funds. The Boards have regularin-person meetings five times a year, including a meeting to consider the approval of the Funds’ investment management agreements and, if necessary, may hold special meetings before their next regular meeting. Each Committee meets regularly to conduct the oversight functions delegated to that Committee by the Boards and reports its findings to the Boards. The Boards and each standing Committee conduct annual assessments of their oversight function and structure. The Boards have determined that the Boards’ leadership structure is appropriate because it allows the Boards to exercise independent judgment over management and to allocate areas of responsibility among Committees and the Boards to enhance oversight.

The Boards decided to separate the roles of Chair and Chief Executive Officer from theCo-Chairs because they believe that anhaving independent Chair:Co-Chairs:

The Boards have engaged the Advisor to manage the Funds on aday-to-day basis. Each Board is responsible for overseeing the Advisor, other service providers, the operations of each Fund and associated risks in accordance with the provisions of the 1940 Act, state law, other applicable laws, each Fund’s charter, and each Fund’s investment objective(s) and strategies. The Boards review, on an ongoing basis, the Funds’ performance, operations, and investment strategies and techniques. The Boards also conduct reviews of the Advisor and its role in running the operations of the Funds.

Day-to-day risk management with respect to the Funds is the responsibility of the Advisor or other service providers (depending on the nature of the risk), subject to the supervision byof the Advisor. The Funds are 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 Advisor or other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Funds. Risk oversight is part of the Boards’ general oversight of the Funds and is addressed as part of various Board and Committee activities. The Boards, directly or through Committees, also review reports from, among others, management, the independent registered public accounting firm for the Funds, the Advisor, and internal auditors for the Advisor or its affiliates, as appropriate, regarding risks faced by the Funds and management’s or the service providers’ risk functions. The Committee system facilitates the timely and efficient consideration of matters by the Board Members and facilitates effective oversight of compliance with legal and regulatory requirements and of the Funds’ activities and associated risks. The Boards have appointedapproved the appointment of a Chief Compliance Officer, who oversees the implementation and testing of the Funds’ compliance program and reports regularly to the Boards regarding compliance matters for the Funds and their service providers. The Independent Board Members have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Compensation. Information relating to compensation paid to the Board Members for each Fund’s most recent fiscal year is set forth inAppendix B.

Equity Securities Owned by Board Members and Board Nominees. Information relating to the amount of equity securities owned by Board Members/Nominees in the Funds that they oversee as of April 30, 20182020 is set forth inAppendix C.

Attendance of Board Members at Annual Shareholders’ Meetings. It is the policy of all the Funds to encourage Board Members to attend the annual shareholders’ meeting. All but twoone of the incumbent Board Members of each Fund in office at the time attended last year’s annual shareholders’ meeting.

Board Meetings. During the calendar year 2017,2019, the Board of each Fund met nineeight times.

Delinquent Section 16(a) Beneficial Ownership Reporting Compliance.Reports. Section 16(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) and the rules thereunder requires the Funds’ Board Members, executive officers, persons who own, either directly or indirectly, more than ten percent of a registered class of a Fund’s equity securities, the Advisor and certain officers of the Advisor (the “Section 16 insiders”), including in some cases former Section 16 insiders for a period of up to 6 months, to file reports on holdings of, and transactions in, Fund shares with the Securities and Exchange Commission (“SEC”) and to furnish the Funds with copies of all such reports.SEC. Based solely on a review of copies of such reports furnished to the relevant Funds during the relevant Funds’ most recent fiscal year and representations from these Section 16 insiders, or former Section 16 insiders, as applicable, with respect to the relevant Funds’ most recent fiscal year, each Fund believes that its Section 16 insiders met all such applicable SEC filing requirements for the Fund’s most recently concluded fiscal year, except for any late filings disclosed in previous proxy statements and certain inadvertent late filings.

Your Board recommends that you vote “FOR” the election of each Board Nominee to the Board of your Fund(s).

VOTE REQUIRED AND MANNER OF VOTING PROXIES

A quorum of shareholders is required to take action at the meeting. For BlackRock Investment Quality Municipal Trust, Inc. (BKN), BlackRock Income Trust, Inc. (BKT), BlackRock Enhanced Capital and Income Fund, Inc.

(CII), BlackRock Debt Strategies Fund, Inc. (DSU), BlackRock Enhanced Government Fund, Inc. (EGF), BlackRock Floating Rate Income Strategies Fund, Inc. (FRA), BlackRock Corporate High Yield Fund, Inc. (HYT) and BlackRock MuniAssets Fund, Inc. (MUA), the holders of 1/3one-third of the shares entitled to vote on any matter at a shareholder meeting, either present in person or by proxy, shall constitute a quorum for purposes of conducting business on such matter. For the remainder of the Funds, the holders of a majority of the shares entitled to vote on any matter at a shareholder meeting present in person or by proxy shall constitute a quorum for purposes of conducting business on such matter. The affirmative vote of a plurality of the votes cast with respect to a Board Nominee at a meeting at which a quorum is present is necessary to elect each of the respective Board Nominees under Proposal 1 for each respective Fund. Because each Fund requires the affirmative vote of a plurality of votes to elect each of the Board Nominees, withheld votes and brokernon-votes, if any, will not have an effect on the outcome of Proposal 1. A “plurality” vote means that the Board Nominees who receive the largest number of votes cast (even if they receive less than a majority) will be elected as Board Members. Since the Board Nominees are running unopposed, each Board Nominee only needs one vote to be elected if there is a quorum present at the meeting.

Votes cast by proxy or in person at each meeting will be tabulated by the inspectors of election appointed for that meeting. The inspectors of election will determine whether or not a quorum is present at the meeting. The inspectors of election will treat withheld votes and “brokernon-votes,”

if any, as present for purposes of determining a quorum. Brokernon-votes occur when shares are held by brokers or nominees, typically in “street name,” for which proxies have been returned but (a) voting instructions have not been received from the beneficial owners or persons entitled to vote, (b) the broker or nominee does not have discretionary voting power or elects not to exercise discretion on a particular matter and (c) the shares are present at the meeting. Preferred Shares of any Fund held in “street name” may be counted for purposes of establishing a quorum of shareholders of that Fund if no instructions are received one business day before the applicable meeting or, if adjourned, postponed, or delayed, one business day before the day to which the meeting is adjourned, postponed, or delayed.

If you hold your shares directly (not through a broker-dealer, bank or other financial institution) and if you return a signed and dated proxy card that does not specify how you wish to vote on a proposal, your shares will be voted“FOR” the Board Nominees in Proposal 1.

Broker-dealer firms holding shares of a Fund in “street name” for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares on Proposal 1 before the meeting. The Funds understand that, under the rules of the New York Stock Exchange, such broker-dealer firms may for certain “routine” matters, without instructions from their customers and clients, grant discretionary authority to the proxies designated by the Board to vote if no instructions have been received prior to the date specified in the broker-dealer firm’s request for voting instructions. Proposal 1 is a “routine” matter and beneficial owners who do not provide proxy instructions or who do not return a proxy card may have their shares voted by broker-dealer firms in favor of Proposal 1. A properly executed proxy card or other authorization by a beneficial owner of Fund shares that does not specify how the beneficial owner’s shares should be voted on Proposal 1 may be deemed an instruction to vote such shares in favor of Proposal 1.

If you hold shares of a Fund through a bank, orbroker, other financial institution or intermediary (called a service agent), the service agent may be the record holder of your shares. At the meeting, a service agent will vote shares for which it receives instructions from its customers in accordance with those instructions. A properly executed proxy card or other authorization by a shareholder that does not specify how the shareholder’s shares should be voted on a proposal may be deemed

to authorize a service provider to vote such shares in favor of the proposal. Depending on its policies, applicable law or contractual or other restrictions, a service agent may be permitted to vote shares with respect to which it has not received specific voting instructions from its customers. In those cases, the service agent may, but is not required to, vote such shares in the same proportion as those shares for which the service agent has received voting instructions. This practice is commonly referred to as “echo voting.”

If you beneficially own shares that are held in “street name” through a broker-dealer or that are held of record by a service agent, and if you do not give specific voting instructions for your shares, they may not be voted at all or, as described above, they may be voted in a manner that you may not intend. Therefore, you are strongly encouraged to give your broker-dealer or service agent specific instructions as to how you want your shares to be voted.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board Members, including a majority of the Independent Board Members, of each Fund have selected Deloitte & Touche LLP (“D&T”) as the independent registered public accounting firm for the Funds.

A representative of D&T is expected to be present at the meeting. The representative of D&T will have the opportunity to make a statement at the meeting if he or she desires to do so and is expected to be available to respond to appropriate questions.

Each Fund’s Audit Committee has discussed with D&T the matters required to be discussed by the Statement on Auditing Standards No. 3101, as amended (AICPA, Professional Standards,AU-C section 260), as adopted byapplicable requirements of the Public Company Accounting Oversight Board (“PCAOB”). and the SEC.

Each Fund’s Audit Committee has received from D&T the written disclosures and the letter required by PCAOB Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, has discussed D&T’s independence with D&T, and has considered the compatibility ofnon-audit services with the independence of the independent registered public accounting firm.

Each Fund’s Audit Committee also reviews and discusses the Fund’s financial statements with Fund management and the independent registered public accounting firm. If any material concerns arise during the course of the audit and the preparation of the audited financial statements mailed to shareholders and included in the Fund’s annual report to shareholders, the Audit Committee would be notified by Fund management or the independent registered public accounting firm. The Audit Committees received no such notifications for any Fund during its most recently completed fiscal year. Following each Fund’s Audit Committee’s review and discussion with the Fund’s independent registered public accounting firm, pursuant to authority delegated by its respective Board, each Fund’s Audit Committee approved the respective Fund’s audited financial statements for the Fund’s most recently completed fiscal year (each Fund’s fiscal year end is set forth inAppendix HG) for inclusion in the Fund’s annual report to shareholders.

Appendix HG sets forth for each Fund the fees billed by that Fund’s independent registered public accounting firm for the two most recent fiscal years for all audit,non-audit, tax and all other services provided directly to the Fund. The fee information inAppendix HG is presented under the following captions:

(a)    Audit Fees—fees related to the audit and review of the financial statements included in annual reports and registration statements, and other services that are normally provided in connection with statutory and regulatory filings or engagements, includingout-of-pocket expenses.

(b)    Audit-Related Fees—fees related to assurance and related services that are reasonably related toassociated with the performance of the audit or review of financial statements, but not reported under “Audit Fees,” including accounting consultations, agreed-upon procedure reports, attestation reports, comfort lettersout-of-pocket expenses and internal control reviews not required by regulators.

(c)    Tax Fees—fees associated with tax compliance and/or tax preparation, tax advice and tax planning, as applicable. Tax compliance and preparation include services such as the filing or amendment of federal, state or local income tax returns, and services relating to regulated investment company qualification reviews, taxable income and tax distribution calculations. All of the fees included under “Tax Fees” inAppendix HG relate solely to services provided for tax compliance and/or tax preparation, and none of such fees relate to tax advice, tax planning or tax consulting.

(d)    All Other Fees—fees for products and services provided to the Fund other than those reported under “Audit Fees,” “Audit-Related Fees” and “Tax Fees.”

(e)    AggregateNon-Audit Fees for Services Provided to Each Fund and its Affiliated Service ProvidersPre-Approved by the Audit Committee—the sum of the fees shown under “Audit-Related

Fees,” “Tax Fees,” and “All Other Fees” and fees paid by each Fund’s Affiliated Service Providers to the Fund’s independent registered public accounting firm.

Each Fund’s Audit Committee is required to approve all audit engagement fees and terms for the Fund. Each Fund’s Audit Committee also is required to consider and approve (i) the provision by the Fund’s independent registered public accounting firm of anynon-audit services to the Fund, and (ii) the provision by the Fund’s independent registered public accounting firm ofnon-audit services to BlackRock and any entity controlling, controlled by or under common control with BlackRock that provides ongoing services to the Fund (“Affiliated Service Providers”) to the extent that such approval (in the case of this clause (ii)) is required under applicable regulations of the SEC. SeeAppendix HG to this Proxy Statement for information about the fees paid by the Funds, their investment advisers, and Affiliated Service Providers to each Fund’s independent registered public accounting firm.

The Audit Committee of each Fund complies with applicable laws and regulations with regard to thepre-approval of services. Audit, audit-related and tax compliance services provided to a Fund on an annual basis require specificpre-approval by the Fund’s Audit Committee. As noted above, each Fund’s Audit Committee must also approve othernon-audit services provided by the Fund’s independent registered public accounting firm to the Fund and to the Fund’s Affiliated Service Providers that relate directly to the operations and financial reporting of the Fund. Each Fund’s Audit Committee has implemented policies and procedures by which such services may be approved other than by the full Audit Committee. Subject to such policies and procedures, including applicable dollar limitations, each Fund’s Audit Committee maypre-approve, without consideration on a specificcase-by-case basis (“generalpre-approval”), certain permissiblenon-audit services that the Audit Committee believes are (a) consistent with the SEC’s auditor independence rules and (b) routine and recurring services that will not impair the independence of the independent registered public accounting firm. Each service approved subject to generalpre-approval is presented to each Fund’s Audit Committee for ratification at the next regularly scheduledin-person Board meeting.

For each Fund’s two most recently completed fiscal years, there were no services rendered by D&T to the Funds for which the generalpre-approval requirement was waived.

Fees fornon-audit services provided to each Fund’s Affiliated Service Providers for whichpre-approval by such Fund’s Audit Committee was required for the calendar years ended December 31, 20172019 and December 31, 20162018 were $2,129,000$2,050,500 and $2,154,000.$2,224,000, respectively. These fees were paid in their entirety by BlackRock in connection with services provided to the Affiliated Service Providers of each Fund and of other BlackRockopen-end andclosed-endfunds in theClosed-End Complexprimarily for a service organization controls review and secondarily, a subscription to the Deloitte Accounting Research Tool.

Each Fund’s Audit Committee has considered the provision ofnon-audit services that were rendered by D&T to the Fund’s Affiliated Service Providers that were notpre-approved (and did not requirepre-approval) in connection with determining such auditor’s independence. All services provided by D&T to each Fund and each Fund’s Affiliated Service ProviderProviders that requiredpre-approval werepre-approved during the Fund’s most recently completed fiscal year.

The Audit Committee of each Fund consists of the following Board Members:

Karen P. Robards (Chair);

Each memberof the members of the Audit Committee and Compliance Committee is paid an additional annual retainer of $30,000 and $12,500,$25,000, respectively, for his or her service on such committee.

The Independent Board Members have agreed that a maximum of 50% of each Independent Board Member’s total compensation paid by funds in theClosed-End BlackRock Fixed-Income Complex may be deferred pursuant to theClosed-End BlackRock Fixed-Income Complex’s deferred compensation plan. Under the deferred compensation plan, deferred amounts earn a return for the Independent Board Members as though equivalent dollar amounts had been invested in common shares of certain funds in theClosed-End BlackRock Fixed-Income Complex selected by the Independent Board Members. This has approximately the same economic effect for the Independent Board Members as if they had invested the deferred amounts in such other funds in theClosed-End BlackRock Fixed-Income Complex. The deferred compensation plan is not funded and obligations thereunder represent general unsecured claims against the general assets of a fund and are recorded as a liability for accounting purposes.

The following table sets forth the aggregate compensation, including deferred compensation amounts, paid to each Independent Board Member by each Fund during its most recently completed fiscal year and by theClosed-End Complexall BlackRock-advised funds for the most recently completed calendar year. Messrs. Perlowski and Fairbairn serve without compensation from the Funds because of their affiliation with BlackRock, Inc. and the Advisor.
