Part F of Form N-PORT was prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and in conformity with the applicable rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) related to interim filings. Part F of Form N-PORT does not include all information and footnotes required by U.S. GAAP for complete financial statements. Certain footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted from this report pursuant to the rules of the SEC. For a full set of the Fund’s notes to financial statements, please refer to the Fund’s most recently filed annual or semi-annual report.

Fair Value Measurements

The Fund's investments in securities are recorded at their estimated fair value. Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Level 1  –     Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.

Level 2  –     Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.).

Level 3  –     Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

The inputs or methodologies used for valuing securities are not an indication of the risks associated with investing in those securities. The following is a summary of the Fund’s fair value measurements as of the end of the reporting period:

	Level 1	Level 2	Level 3	Total
Long-Term Investments:
Municipal Bonds	$ —	$1,221,701,754	$ —	$1,221,701,754

(1)	All percentages shown in the Portfolio of Investments are based on net assets applicable to common shares unless otherwise noted.
(2)	Optional Call Provisions: Dates (month and year) and prices of the earliest optional call or redemption. There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns.
(3)	For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies.
(4)	Effective February 12, 2019, the par value of the original bonds was replaced with taxable and tax exempt Puerto Rico Sales Tax Financing Corporation (commonly known as COFINA) bond units that are collateralized by a bundle of zero and coupon paying bonds. The quantity shown represents units in a trust, which were assigned according to the original bond’s accreted value. These securities do not have a stated coupon interest rate and income will be recognized through accretion of the discount associated with the trust units. The factor at which these units accrete can also decrease, primarily for principal payments generated from coupon payments received or dispositions of the underlying bond collateral. The quantity of units will not change as a result of these principal payments.
(5)	Step-up coupon bond, a bond with a coupon that increases ("steps up"), usually at regular intervals, while the bond is outstanding. The rate shown is the coupon as of the end of the reporting period.
(6)	Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, which ensure the timely payment of principal and interest.
(7)	Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.
(8)	MuniFund Preferred Shares, net of deferred offering costs as a percentage of Total Investments is 11.5%.
(9)	Variable Rate Demand Preferred Shares, net of deferred offering costs as a percentage of Total Investments is 23.8%.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
ETM	Escrowed to maturity
IF	Inverse floating rate security issued by a tender option bond (“TOB”) trust, the interest rate on which varies inversely with the Securities Industry Financial Markets Association (SIFMA) short-term rate, which resets weekly, or a similar short-term rate, and is reduced by the expenses related to the TOB trust.
UB	Underlying bond of an inverse floating rate trust reflected as a financing transaction.
