See Schedule of Investments for fair values in each industry and identification of foreign issuer and/or geography. The table above is presented by Investment Type. Industries are presented within an Investment Type should such Investment Type include securities classified as two or more levels within the three- tier fair value hierarchy. When applicable each Level 3 security is identified on the Schedule of Investments along with the valuation technique utilized.

A reconciliation of Level 3 investments is presented when the Fund has a material amount of Level 3 investments at the beginning or end of the period in relation to the Fund’s net assets. Management has determined not to provide a reconciliation as the balance of Level 3 investments was not considered to be material to the Fund’s net assets at the beginning or end of the period.

Industries are presented within an Investment Type should such Investment Type include securities classified as two or more levels within the three- tier fair value hierarchy. When applicable each Level 3 security is identified on the Schedule of Investments along with the valuation technique utilized.

A reconciliation of Level 3 investments is presented when the Fund has a material amount of Level 3 investments at the beginning or end of the period in relation to the Fund’s net assets. Management has determined not to provide a reconciliation as the balance of Level 3 investments was not considered to be material to the Fund’s net assets at the beginning or end of the period.

1. ORGANIZATION  

Lord Abbett Municipal Income Fund, Inc. (the “Company”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as an open-end management investment company. The Company was organized as a Maryland corporation on December 27, 1983.

The Company currently consists of the following eight funds (separately, a “Fund” and collectively, the “Funds”) their respective active share classes:

Funds	Classes
Lord Abbett Short Duration Tax Free Fund (“Short Duration”)	A,C,F,F3 and I
Lord Abbett Intermediate Tax Free Fund (“Intermediate”)	A,C,F,F3 and I
Lord Abbett National Tax-Free Income Fund (“National”)	A,C,F,F3 and I
Lord Abbett High Income Municipal Bond Fund	A,C,F,F3 and I
Lord Abbett Short Duration High Income Municipal Bond Fund	A,C,F,F3 and I
Lord Abbett California Tax-Free Income Fund (“California”)	A,C,F,F3 and I
Lord Abbett New Jersey Tax-Free Income Fund (“New Jersey”)	A,F,F3 and I
Lord Abbett New York Tax-Free Income Fund (“New York”)	A,C,F,F3 and I

Short Duration, Intermediate, AMT Free and National are diversified as defined in the Act. High Income, Short Duration High Income, California, New Jersey and New York are non-diversified as defined in the Act.

The investment objective of each Fund (except for High Income and Short Duration High Income) is to seek the maximum amount of interest income exempt from federal income tax as is consistent with reasonable risk. The investment objective of High Income and Short Duration High Income is to seek a high level of income exempt from federal income tax. Each of California, New Jersey and New York also seeks as high a level of interest income exempt from the personal income tax of its corresponding state as is consistent with reasonable risk. In addition, New York seeks as high a level of interest income exempt from New York City personal income tax as is consistent with reasonable risk.

2. SIGNIFICANT ACCOUNTING POLICIES  

(a)	Investment Valuation-Under procedures approved by the Funds’ Board of Directors (the “Board”), Lord, Abbett & Co. LLC (“Lord Abbett”), each Fund’s investment manager, has formed a Pricing Committee to administer the pricing and valuation of portfolio investments and to ensure that prices utilized reasonably reflect fair value. Among other things, these procedures allow the Funds to utilize independent pricing services, quotations from securities and financial instrument dealers and other market sources to determine fair value.
	Securities are valued based on evaluated prices supplied by independent pricing services, which reflect broker/dealer supplied valuations and the independent pricing services’ own electronic data processing techniques. Exchange traded options and futures contracts are valued at the last sale price in the market where they are principally traded. If no sale has occurred, the mean between the most recently quoted bid and asked prices is used.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee. The Pricing Committee considers a number of factors, including observable and unobservable inputs, when arriving at fair value. The Pricing Committee may use observable inputs such as yield curves, broker quotes, observable trading activity, option

159

Notes to Schedule of Investments (unaudited)(continued)

	adjusted spread models and other relevant information to determine the fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and may employ techniques such as reviewing related market activity, reviewing inputs and assumptions, and retrospectively comparing prices of subsequent purchases and sales transactions to fair value determinations made by the Pricing Committee.
	Investments in open-end money market mutual funds are valued at their NAV as of the close of each business day. Short-term securities with 60 days or less remaining to maturity are valued using the amortized cost method, which approximates fair value.
(b)	Fair Value Measurements-Fair value is defined as the price that each Fund would receive upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market of 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. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk - for example, the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and/or the risk inherent in the inputs to the valuation technique. Inputs may be observable or unobservable. 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 three-tier hierarchy classification is determined based on the lowest level of inputs that is significant to the fair value measurement, and is summarized in the three broad Levels listed below:

•	Level 1 -	unadjusted quoted prices in active markets for identical investments;
•	Level 2 -	other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and
•	Level 3 -	significant unobservable inputs (including each Fund’s own assumptions in determining the fair value of investments).

A summary of inputs used in valuing the Fund’s investments as of December 31, 2021 and, if applicable, Level 3 rollforwards for the six month then ended is included in each Fund’s Schedule of Investments.

Changes in valuation techniques may result in transfers into or out of an assigned level within the three-tier hierarchy. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. FEDERAL TAX INFORMATION  

It is the policy of the Fund to meet the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all taxable income and capital gains to its shareholders. Therefore, no income tax provision is required.

Each Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on each Fund’s filed U.S. federal tax returns remains open generally three years after the filing of the tax return. The statutes of limitations on each Fund’s, state and local tax returns may remain open for an additional year depending upon the jurisdiction.

4. SECURITIES LENDING AGREEMENT  

The Funds have established a securities lending agreement with Citibank, N.A. for the lending of securities to qualified brokers in exchange for securities or cash collateral equal to at least the market value of securities loaned, plus interest, if applicable. Cash collateral is invested in an approved money market fund. In accordance with the Funds’ securities lending agreement, the market value of securities on loan is determined each day at the close of business and any additional collateral required to cover the value of securities on loan is delivered to the Funds on the next business day. As with other extensions of credit, the Funds may experience a delay in the recovery of their securities or incur a loss should the borrower of the securities breach its agreement with the Funds or becomes insolvent at a time when the collateral is insufficient to cover the cost of repurchasing securities on loan. Any income earned from securities lending is included in Securities lending net income on the Statements of Operations.

The initial collateral received by the Fund is required to have a value equal to at least 100% of the market value of the securities loaned. The collateral must be marked-to-market daily to cover increases in the market value of the securities loaned (or potentially a decline in the value of the collateral). In general, the risk of borrower default will be borne by Citibank, N.A.; the Funds will bear the risk of loss with respect to the investment of the cash collateral. The advantage of such loans is that the Funds continue to receive income on loaned securities while receiving a portion of any securities lending fees and earning returns on the cash amounts which may be reinvested for the purchase of investments in securities.

As of December 31, 2021, the Funds did not loan any securities.
