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 utilizing valuation methods approved by the Board of Directors/Trustees. 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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:

(1) All percentages shown in the Portfolio of Investments are based on net assets.

(4) Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.  
(5) Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.

On December 9, 2013, AMR emerged from federal bankruptcy with the acceptance of its reorganization plan by the bankruptcy court. Under the settlement agreement established to meet AMR’s unsecured bond obligations, the bondholders, including the Fund, received a distribution of AAL preferred stock which was converted to AAL common stock over a 120-day period. Every 30 days, a quarter of the preferred stock was converted to AAL common stock based on the 5-day volume-weighted average price and the amount of preferred shares tendered during the optional preferred conversion period.

Fair Value Measurements
The Fund's investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board of Directors/Trustees. 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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:

(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) Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.  
(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.

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 utilizing valuation methods approved by the Board of Directors/Trustees. 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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 $ — $286,983,750 $ — $286,983,750
    
(1) All percentages shown in the Portfolio of Investments are based on net assets.  
(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) Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.  
(5) 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.  
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.

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.

Fair Value Measurements
The Fund's investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board of Directors/Trustees. 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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.
      80
Nuveen Massachusetts Municipal Bond Fund (continued)
Portfolio of Investments    May 31, 2021
(Unaudited)
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:

Long-Term Investments:        
Municipal Bonds $ — $698,462,846 $ — $698,462,846
    
(1) All percentages shown in the Portfolio of Investments are based on net assets.  
(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) 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.  
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.

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 utilizing valuation methods approved by the Board of Directors/Trustees. 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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).
95      
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:

(1) All percentages shown in the Portfolio of Investments are based on net assets.  
(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) Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.  
(5) Investment, or portion of investment, has been pledged to collateralize the net payment obligations for investments in inverse floating rate transactions.  
(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) Other assets less liabilities includes the unrealized appreciation (depreciation) of certain over-the-counter (“OTC”) derivatives as well as the OTC cleared and exchange-traded derivatives, when applicable.  
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.

The Fund's investments in securities are recorded at their estimated fair value utilizing valuation methods approved by the Board of Directors/Trustees. 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. U.S. GAAP establishes the three-tier hierarchy which 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 management’s 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:

(1) All percentages shown in the Portfolio of Investments are based on net assets.  
(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) 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.  
(5) Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.  
(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.
