Expense Example

As a shareholder of a Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments (these charges vary among the share classes); and (2) ongoing costs, including management fees; distribution and service (12b-1) fees (these charges vary among the share classes); and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (October 1, 2018 through March 31, 2019).

Actual Expenses

For each class of each Fund, the first line of the table on the following pages provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading titled “Expenses Paid During Period 10/1/18 – 3/31/19” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

For each class of each Fund, the second line of the table on the following pages provides information about hypothetical account values and hypothetical expenses based on the Fund’s actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund’s actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in a Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Short Duration Tax Free Fund

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads). Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

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”) and 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 Yield Municipal Bond Fund (“High Yield”)	A,C,F,F3 and I
Lord Abbett Short Duration High Yield Municipal Bond Fund (“Short Duration High Yield”)	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 and National are diversified as defined in the Act. High Yield, Short Duration High Yield, California, New Jersey and New York are non-diversified as defined in the Act.

On March 22, 2019, National acquired the net assets of Lord Abbett AMT Free Municipal Bond Fund (“AMT Free”), which was another fund of the Company. Refer to Note 15 for additional information.

The investment objective of each Fund (except for High Yield and Short Duration High Yield) 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 Yield and Short Duration High Yield 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.

Each class has different expenses and dividends. A front-end sales charge is normally added to the net asset value (“NAV”) for Class A shares. There is no front-end sales charge in the case of Class C, F, F3 and I shares, although there may be a contingent deferred sales charge (“CDSC”) in certain cases as follows: Class A shares purchased without a sales charge and redeemed before the first day of the month in which the one-year anniversary of the purchase falls (subject to certain exceptions as set forth in each Fund’s prospectus); Class C shares redeemed before the first anniversary of purchase. Class C shares will convert automatically into Class A shares on the 25th day of the month (or, if the 25th is not a business day, the next business day thereafter) following the tenth anniversary of the month on which the purchase order was accepted.

The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. These Funds are considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies.

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 quoted 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 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)	Security Transactions–Security transactions are recorded as of the date that the securities are purchased or sold (trade date). Realized gains and losses on sales of portfolio securities are calculated using the identified-cost method. Realized and unrealized gains (losses) are allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day.
(c)	Investment Income–Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis as earned. Discounts are accreted and premiums are amortized using the effective interest method and are included in Interest and other income on the Statements of Operations. Investment income is allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day.
(d)	Income Taxes–It is the policy of each 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 for the fiscal years ended September 30, 2015 through September 30, 2018. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

157

Notes to Financial Statements (unaudited)(continued)

(e)	Expenses–Expenses incurred by the Company that do not specifically relate to an individual fund are generally allocated to the Funds within the Company on a pro rata basis by relative net assets. Expenses, excluding class-specific expenses, are allocated to each class of shares based upon the relative proportion of net assets at the beginning of the day. Each share class bears its class-specific share of expenses.
(f)	Futures Contracts–Each Fund may purchase and sell futures contracts to enhance returns, to attempt to economically hedge some of its investment risk, or as a substitute position in lieu of holding the underlying asset on which the instrument is based. At the time of entering into a futures transaction, an investor is required to deposit and maintain a specified amount of cash or eligible securities called “initial margin.” Subsequent payments made or received by a Fund called “variation margin” are made on a daily basis as the market price of the futures contract fluctuates. Each Fund will record an unrealized gain (loss) based on the amount of variation margin. When a contract is closed, a realized gain (loss) is recorded equal to the difference between the opening and closing value of the contract.
(g)	When-Issued Municipal Bonds–Each Fund may purchase new issues of municipal bonds, which are generally offered on a when-issued basis, with delivery and payment normally taking place approximately one month after the purchase date.
(h)	Municipal Bonds Held in Trust–Each Fund may invest in leveraged residual certificates (“TOB Residuals”) issued by tender option bond trusts (“TOBs”). A TOB is established by a third party sponsor forming a special purpose entity into which a Fund, or an agent on behalf of the Fund, transfers municipal securities. A TOB typically issues two classes of beneficial interests: short-term floating rate certificates (trust certificates), which are sold to third party investors, and residual certificates, which are generally issued to a Fund which made the transfer or to affiliates of the Fund. Each Fund’s transfer of the municipal securities to a TOB is accounted for as a secured borrowing, therefore the municipal securities deposited into a TOB are presented as investments in a Fund’s Schedule of Investments and the proceeds from the transactions are reported as a liability for trust certificates on the Statements of Assets and Liabilities. Similarly, proceeds from residual certificates issued to affiliates, if any, from the transaction are included in the liability for trust certificates. Interest income from the underlying security is recorded by a Fund on an accrual basis. Interest expense incurred on the secured borrowing and other expenses related to remarketing, administration and trustee services to a TOB are reported as expenses of a Fund. The floating rate certificates have interest rates that generally reset weekly and their holders have the option to tender certificates to the TOB for redemption at par at each reset date. The residual interests held by a Fund include the right of the Fund (1) to cause the holders of a proportional share of floating rate certificates to tender their certificates at par and (2) to transfer a corresponding share of the municipal securities from the TOB to the Fund. The TOB may also be terminated without the consent of the Fund upon the occurrence of certain events as defined in the TOB agreements. Such termination events may include the bankruptcy or default of the municipal bond, a substantial downgrade in credit quality of the municipal bond, the inability of the TOB to obtain quarterly or annual renewal of the liquidity support agreement, a substantial decline in market value of the municipal bond or the inability to remarket the short-term floating rate certificates to third party investors.

158

Notes to Financial Statements (unaudited)(continued)

The following is a summary of each Fund’s liability for trust certificates, range of interest rates for such certificates and the aggregate value of the underlying municipal securities transferred to TOBs as of March 31, 2019, as well as the average trust certificates for the six months ended March 31, 2019:

					Underlying		Average
			Interest Rate		Municipal Bonds		Trust
	Liability for		or Range of		Transferred		Certificates
Fund	Trust Certificates		Interest Rates		to TOBs		Outstanding
Short Duration	$	–		–	$	–	$	–
Intermediate		1,250,000		1.53%		2,537,425		1,250,000
National		26,250,000	1.53% - 1.56%			56,341,325		26,250,000
High Yield		2,500,000		1.53%		5,074,850		4,750,000
Short Duration High Yield		–		–		–		–
California		–		–		–		–
New Jersey		–		–		–		–
New York		–		–		–		–

	Financial transactions executed through TOBs generally will underperform the market for fixed rate municipal bonds in a rising interest rate environment, but tend to outperform the market for fixed rate municipal bonds when interest rates decline or remain relatively stable. Should short-term interest rates rise, a Fund’s investment in TOB Residuals likely will adversely affect a Fund’s net investment income and distributions to shareholders. Fluctuations in the market value of municipal securities deposited into the TOB may adversely affect a Fund’s NAV per share. As of March 31, 2019, the carrying value of each Fund’s Liability for Trust Certificates approximates its fair value.
	While the Funds’ investment policies and restrictions expressly permit investments in inverse floating rate securities such as TOB Residuals, they generally do not allow the Funds to borrow money for purposes of making investments. The Funds’ management believes that the Funds’ restrictions on borrowings do not apply to TOB transactions, accounted for as secured borrowings.
(i)	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:

159

Notes to Financial Statements (unaudited)(continued)

•	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 each Fund’s investments and other financial instruments as of March 31, 2019 and, if applicable, Level 1/Level 2 transfers and Level 3 rollforwards for the six months 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. All transfers between different levels within the three-tier hierarchy are deemed to have occurred as of the beginning of the reporting period. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

3. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES

4. DISTRIBUTIONS AND CAPITAL LOSS CARRYFORWARDS  

Dividends from net investment income, if any, are declared daily and paid monthly. Taxable net realized gains from investment transactions, reduced by allowable capital loss carryforwards, if any, are declared and distributed to shareholders at least annually. The capital loss carryforward amount, if any, is available to offset future net capital gains. Dividends and distributions to shareholders are

162

Notes to Financial Statements (unaudited)(continued)

recorded on the ex-dividend date. The amounts of dividends and distributions from net investment income and net realized capital gains are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. These book/tax differences are either considered temporary or permanent in nature. To the extent these differences are permanent in nature, such amounts are reclassified within the components of net assets based on their federal tax basis treatment; temporary differences do not require reclassification. Dividends and distributions, which exceed earnings and profits for tax purposes, are reported as a tax return of capital.

The tax character of distributions paid during the six months ended March 31, 2019 and fiscal year ended September 30, 2018 were as follows:

		Short Duration		Intermediate

In accordance with the Regulated Investment Company Modernization Act of 2010, each Fund will carryforward capital losses incurred in taxable years beginning after December 22, 2010 (“post-enactment losses”) indefinitely. Post-enactment losses will also retain their character as either short-term or long-term and be utilized before any pre-enactment losses.

As of March 31, 2019, the aggregate unrealized security gains and losses on investments and other financial instruments based on cost for U.S. federal income tax purposes were as follows:

6. DISCLOSURES ABOUT DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES  

Each Fund, except Short Duration entered into U.S. Treasury futures contracts during the six months ended March 31, 2019 (as described in note 2(f)) to economically hedge against changes in interest rates. The Funds bear the risk of interest rates moving unexpectedly, in which case the Funds may not achieve the anticipated benefits of the futures contracts and realize a loss. There is minimal counterparty credit risk to the Funds since futures are exchange traded and the exchange’s clearinghouse, as counterparty to all exchange traded futures, guarantees futures against default.

As of March 31, 2019, the Funds had interest rate futures contracts with cumulative net unrealized appreciation/depreciation which are included in the Schedules of Investments. Only the current day’s variation margin is included in the Statements of Assets and Liabilities. The net realized gain (loss) on futures contracts and change in unrealized appreciation/depreciation on futures contracts are included in the Statements of Operations under the captions Net realized gain (loss) on futures contracts and Net change in unrealized appreciation/depreciation on futures contracts, respectively.

The following is a summary of U.S. Treasury futures contracts as of and during the six months ended March 31, 2019:

							Net Change in
	Net Unrealized						Unrealized			Average
	Depreciation as of			Net Realized			Appreciation/			Number of
	March 31, 2019			Loss			(Depreciation)			Contracts*

* Calculated based on the number of contracts for the six months ended March 31, 2019.

7. DISCLOSURES ABOUT OFFSETTING ASSETS AND LIABILITIES  

The Financial Accounting Standards Board (“FASB”) requires disclosure to help better assess the effect or potential effect of offsetting arrangements on a fund’s financial position. These requirements include the disclosure of gross and net information about recognized assets and liabilities eligible for offset in the statement of assets and liabilities; and to disclose such amounts subject to an enforceable master netting agreement or similar agreement, by counterparty. A master netting agreement is an agreement between a fund and a counterparty which provides for the net settlement of amounts owed under all contracts traded under that agreement, as well as cash collateral, through a single payment by one party to the other in the event of default on or termination of any one contract. The Funds’ accounting policy with respect to balance sheet offsetting is that, absent an event of default by the counterparty or a termination of the agreement, the master netting agreement does not result in an offset of reported amounts of financial assets and liabilities in the statement of assets and liabilities across transactions between a Fund and the applicable counterparty. As of March 31, 2019, the Funds did not have assets or liabilities subject to the FASB disclosure requirements.

8. DIRECTORS’ REMUNERATION  

The Company’s officers and the one Director who are associated with Lord Abbett do not receive any compensation from the Company for serving in such capacities. Independent Directors’ fees are allocated among all Lord Abbett-sponsored funds based on the net assets of each Fund. There is an equity-based plan available to all Independent Directors under which Independent Directors must defer receipt of a portion of, and may elect to defer receipt of an additional portion of, Directors’ fees. The deferred amounts are treated as though equivalent dollar amounts had been invested in the Funds. Such amounts and earnings accrued thereon are included in Directors’ fees on the Statements of Operations and in Directors’ fees payable on the Statements of Assets and Liabilities and are not deductible for U.S. federal income tax purposes until such amounts are paid.

9. EXPENSE REDUCTIONS  

The Company has entered into an arrangement with its transfer agent and custodian, whereby credits realized as a result of uninvested cash balances are used to reduce a portion of each Fund’s expenses.

10. LINE OF CREDIT  

During the period ended December 20, 2018, the Funds and certain other funds managed by Lord Abbett (collectively, the “Participating Funds”) participated in a syndicated line of credit facility with various lenders for $1.06 billion (the “Syndicated Facility”), whereas SSB participates as a lender and as agent for the lenders. Under the Syndicated Facility, the Participating Funds are subject to graduated borrowing limits of one-third of Fund assets (if Fund assets are less than $750 million), $250 million, $300 million, $350 million, or $1 billion, based on past borrowings and likelihood of future borrowings. Effective December 21, 2018, the Participating Funds entered into an amended Syndicated Facility with various lenders for $1.1 billion based on the same terms as described above.

During the period ended March 31, 2019, the Participating Funds participated in an additional line of credit facility with SSB for $250 million (the “Bilateral Facility,” and together with the Syndicated Facility, the “Facilities”). Under the Bilateral Facility, each Participating Fund may borrow up to the lesser of $250 million or one-third of Fund assets. The Facilities are to be used for temporary or emergency purposes to satisfy redemption requests and manage liquidity.

For the six months ended March 31, 2019, the Funds did not utilize the Facilities.

11. INTERFUND LENDING PROGRAM  

Pursuant to an exemptive order issued by the U.S. Securities and Exchange Commission (“SEC exemptive order”) certain registered open-end management investment companies managed by Lord Abbett, including each Fund, participate in a joint lending and borrowing program (the “Interfund Lending Program”). The SEC exemptive order allows the Funds to borrow money from and lend money to each other for temporary or emergency purposes subject to the limitations and conditions.

During the six months ended March 31, 2019, the following Fund participated as a lender in the Interfund Lending Program. For the period in which the loan was outstanding, the average amount loaned, interest rate and interest income were as follows:

		Average	Interest
Fund	Average Loan	Interest Rate	Income*
Intermediate	$22,000,000	2.23%	$1,344

* Included in the Statement of Operations.

12. CUSTODIAN AND ACCOUNTING AGENT  

SSB is the Company’s custodian and accounting agent. SSB performs custodial, accounting and recordkeeping functions relating to portfolio transactions and calculating each Fund’s NAV.

13. INVESTMENT RISKS  

Each Fund’s performance and the fair value of its investments will vary in response to changes in interest rates and other market factors. As interest rates rise, a Fund’s investments typically will lose value. This risk is usually greater for long-term bonds and particularly for TOB Residuals. As a result, each Fund, to the extent it invests in long-term bonds and TOB Residuals, is subject to such greater market risk. During periods of falling interest rates, a Fund’s investments may gain value; however, because Short Duration and Short Duration High Yield typically invest in shorter term bonds, those Funds are subject to the risk that they will underperform funds invested in longer-term bonds during such periods.

Additional risks that could reduce each Fund’s performance or increase volatility include call risk credit risk, defaulted bonds risk (High Yield and Short Duration High Yield only), derivatives risk, distressed debt risk (High Yield and Short Duration High Yield only), extension risk, governmental risk, industry risk, liquidity risk, market and portfolio management risks, state and territory risks, taxability risk and zero coupon, deferred interest, pay-in-kind, and capital appreciation bonds risk (all Funds except Short Duration, Intermediate, and Short Duration High Yield). Credit risk varies among states based upon the economic and fiscal conditions of each state and the municipalities within the state.

There is the risk that an issuer of a municipal bond may fail to make timely payments of principal or interest to a Fund, a risk that is greater with municipal bonds rated below investment grade (sometimes called “lower rated bonds” or “junk bonds”). High Yield and Short Duration High Yield, and, to a lesser extent, other Funds invest a portion of its assets in such bonds. Some issuers, particularly of junk bonds, may default as to principal and/or interest payments after a Fund purchases their securities. A default, or concerns in the market about an increase in risk of default or the deterioration in the creditworthiness of an issuer, may result in losses to a Fund. Junk bonds are considered predominantly speculative by traditional investment standards. In addition, the market for lower rated municipal bonds generally is less liquid and more volatile than the market for higher rated bonds, subjecting them to greater price fluctuations which could result in losses.

Each of High Yield, Short Duration High Yield, California, New Jersey and New York is non-diversified, which means that it may invest a greater portion of its assets in a single issuer than a diversified fund. Thus, it may be exposed to greater risk.

Because each of California, New Jersey, and New York focuses on a particular state or territory, the Fund’s performance may be more affected by local, state and regional factors than a Fund that invests in municipal bonds issued in many states. These factors may include, for example, economic or political developments, erosion of the tax base and the possibility of credit problems. In addition, downturns or developments in the U.S. economy or in foreign economies or significant world events may harm the performance of any of the Funds (including Short Duration, Intermediate, National, High Yield, and Short Duration High Yield), and may do so disproportionately as a result of the corresponding disproportionate impact of such occurrences on particular state, territory, or local economies.

Each Fund may invest in private activity bonds (sometimes called “AMT paper”). The credit quality of AMT paper usually is directly related to the credit standing of the private user of the facilities.

167

Notes to Financial Statements (unaudited)(continued)

High Yield, Short Duration High Yield and, to a lesser extent, other Funds may invest in TOB Residuals. A TOB Residual, sometimes referred to as an inverse floater or a residual interest bond (“RIB”), is a type of derivative debt instrument with a floating or variable interest rate that moves in the opposite direction of the interest rate on another specific fixed-rate security. Changes in the interest rate on the specific fixed-rate security inversely affect the residual interest paid on the TOB Residual, with the result that when interest rates rise, TOB Residuals’ interest payments are lowered and their value falls faster than securities similar to the specific fixed-rate security. When interest rates fall, not only do TOB Residuals generally provide interest payments that are higher than securities similar to the specific fixed-rate security, but their values generally also rise faster than such similar securities.

In addition, loss may result from a Fund’s investments in certain derivative transactions such as futures contracts, swap transactions, interest rate caps, TOB Residuals and similar transactions. These instruments may be leveraged so that small changes may produce disproportionate and substantial losses to a Fund. They also may increase a Fund’s interest rate risk.

Each Fund may purchase securities on a forward commitment or when-issued basis. Delivery and payment for such securities can take place a month or more after the transaction date. During this period such securities are subject to market fluctuations.

These factors can affect each Fund’s performance.

15. REORGANIZATION  

As of the close of business on March 22, 2019, National acquired the net assets of AMT Free, pursuant to a plan of reorganization. The acquisition was accomplished by a tax-free exchange whereby holders of shares of AMT Free outstanding on March 22, 2019 received shares valued at $201,497,691 of National. AMT Free’s net assets at the date of acquisition, including $8,144,374 of net unrealized appreciation and $(568,733) of accumulated net realized losses, were combined with those of National. The cost basis of securities received from AMT was carried forward.

The total net assets of AMT Free immediately before the transfer were $201,497,691. Total net assets of National immediately before the transfer were $2,150,472,746. Total net assets of National immediately after the transfer were $2,351,970,437.

Net investment income: $37,272,616

Net realized and unrealized gain: $61,824,249

Net increase in net assets resulting from operations: $99,096,865

Approval of Advisory Contract

The Board, including all of the Directors who are not “interested persons” of the Company or of Lord Abbett, as defined in the Investment Company Act of 1940, as amended (the “Independent Directors”), annually considers whether to approve the continuation of the existing management agreement between each Fund and Lord Abbett (the “Agreement”). In connection with its most recent approval, the Board reviewed materials relating specifically to the Agreement, as well as numerous materials received throughout the course of the year, including information about each Fund’s investment performance compared to the performance of one or more appropriate benchmarks. Before making its decision as to each Fund, the Board had the opportunity to ask questions and request further information, taking into account its knowledge of Lord Abbett gained through its meetings and discussions. These meetings and discussions included reviews of Fund performance conducted by members of the Contract Committee, the deliberations of the Contract Committee, and discussions between the Contract Committee and Lord Abbett’s management. The Independent Directors also met with their independent legal counsel in various private sessions at which no representatives of management were present.

The materials received by the Board as to each Fund included, but were not limited to: (1) information provided by Broadridge Financial Solutions (“Broadridge”) regarding the investment performance of the Fund compared to the investment performance of certain funds with similar investment styles as determined by Broadridge, based, in part, on the Fund’s Morningstar category (the “performance peer group”), and the investment performance of one or more appropriate benchmarks; (2) information provided by Broadridge regarding the expense ratios, contractual and actual management fee rates, and other expense components for the Fund and certain funds in the same Morningstar category, with generally the same or similar share classes and operational characteristics, including asset size (the “expense peer group”); (3) certain supplemental investment performance information provided by Lord Abbett; (4) information provided by Lord Abbett on the expense ratios, management fee rates, and other expense components for the Fund; (5) sales and redemption information for the Fund; (6) information regarding Lord Abbett’s financial condition; (7) an analysis of the relative profitability of the Agreement to Lord Abbett; (8) information provided by Lord Abbett regarding the investment management fee schedules for Lord Abbett’s other advisory clients maintaining accounts with a similar investment strategy as the Fund (in the case of Intermediate, National, and Short Duration); and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management and Related Services Generally.The Board considered the services provided by Lord Abbett to each Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all applicable legal requirements. The Board also observed that Lord Abbett was solely engaged in the investment management business and accordingly did not experience the conflicts of interest that may result from being engaged in other lines of business. The Board considered the investment advisory services provided by Lord Abbett to other clients, the fees charged for the services, and the differences in the nature of the services provided to each Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other. After reviewing these and related factors, the Board concluded that each Fund was likely to continue to benefit from the nature, extent and quality of the investment services provided by Lord Abbett under the Agreement.

Investment Performance.The Board reviewed each Fund’s investment performance in relation to that of its performance peer group and one or more appropriate benchmarks as of various periods ended August 31, 2018. As to California, New Jersey, and National, the Board observed that the

Approval of Advisory Contract (continued)

Fund’s investment performance was above the median of the performance peer group for the one-, three-, five-, and ten-year periods. As to High Yield, the Board observed that the Fund’s investment performance was above the median of the performance peer group for the one-, three-, and five-year periods, but below the median for the ten-year period. As to Intermediate, the Board observed that the Fund’s investment performance was above the median of the performance peer group for the ten-year period, equal to the median of the performance peer group for the three- and five-year periods, and below the median for the one-year period. As to New York, the Board observed that the Fund’s investment performance was above the median of the performance peer group for the three- and ten-year periods, equal to the median of the performance peer group for the five-year period, and below the median of the performance peer group for the one-year period. As to Short Duration, the Board observed that the Fund’s investment performance was above the median of the performance peer group for the five-year period, but below for the one- and three-year periods (though the Fund’s performance was within approximately one basis point of the median for the three-year period). The Board also observed that the Fund outperformed its benchmark for each of these periods. As to Short Duration High Yield, the Board observed that the Fund’s investment performance was below the median of the performance peer group for the one- and three-year periods. The Board also considered Lord Abbett’s performance and reputation generally, the performance of other Lord Abbett-managed funds overseen by the Board, and the willingness of Lord Abbett to take steps intended to improve performance when appropriate. After reviewing these and related factors, the Board concluded that each Fund’s Agreement should be continued.

Lord Abbett’s Personnel and Methods.The Board considered the qualifications of the personnel providing investment management services to each Fund, in light of its investment objective and discipline, and other services provided to the Fund by Lord Abbett. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining personnel.

Nature and Quality of Other Services.The Board considered the nature, quality, and extent of compliance, administrative, and other services performed by Lord Abbett and the nature and extent of Lord Abbett’s supervision of third party service providers, including each Fund’s transfer agent and custodian.

Expenses.The Board considered the expense level of each Fund, including the contractual and actual management fee rates, and the expense levels of the Fund’s expense peer group. It also considered how the expense level of each Fund related to those of the expense peer group and the amount and nature of the fees paid by shareholders. As to each of California, High Yield, Intermediate, National, New York, Short Duration, and Short Duration High Yield, the Board observed that the net total expense ratio of the Fund was below the median of the expense peer group. As to New Jersey, the Board observed that the net total expense ratio of the Fund was approximately the same as the median of the expense peer group. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that the expense level of each Fund was reasonable and supported the continuation of the Agreement on behalf of each Fund.

Profitability.As to each Fund, the Board considered the level of Lord Abbett’s operating margin in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. It considered whether each Fund was profitable to Lord Abbett in connection with the Fund’s operation, including the fee that Lord Abbett receives from the Fund

178

Approval of Advisory Contract (concluded)

for providing administrative services to the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to each Fund’s business. The Board considered Lord Abbett’s profit margins excluding Lord Abbett’s marketing and distribution expenses. The Board also considered Lord Abbett’s profit margins, without those exclusions, in comparison with available industry data and how those profit margins could affect Lord Abbett’s ability to recruit and retain personnel. The Board recognized that Lord Abbett’s overall profitability was a factor in enabling it to attract and retain qualified personnel to provide services to each Fund. After reviewing these and related factors, the Board concluded, within the context of its overall approval of the Agreement, that Lord Abbett’s profitability with respect to each Fund was not excessive.

Economies of Scale.As to each Fund, the Board considered the extent to which there had been economies of scale in managing the Fund, whether the Fund’s shareholders had appropriately benefited from such economies of scale, and whether there was potential for realization of any further economies of scale. With respect to each of Intermediate, National, New York, California and High Yield, the Board concluded that the contractual breakpoints in the existing management fee schedule adequately addressed any economies of scale in managing the Fund. With respect to each of New Jersey, Short Duration and Short Duration High Yield, the Board concluded that the contractual breakpoints in the existing management fee schedule, in conjunction with the Fund’s expense limitation agreement, adequately addressed any economies of scale in managing the Fund.

Other Benefits to Lord Abbett.As to each Fund, the Board considered the amount and nature of the fees paid by the Fund and the Fund’s shareholders to Lord Abbett and the Distributor for services other than investment advisory services, such as the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund. The Board also considered the revenues and profitability of Lord Abbett’s investment advisory business apart from its mutual fund business, and the intangible benefits enjoyed by Lord Abbett by virtue of its relationship with each Fund. The Board observed that the Distributor receives 12b-1 fees from certain of the Lord Abbett Funds as to shares held in accounts for which there is no other broker of record, may retain a portion of the 12b-1 fees it receives, and receives a portion of the sales charges on sales and redemptions of some classes of shares of the Lord Abbett Funds. In addition, the Board observed that Lord Abbett accrues certain benefits for its business of providing investment advice to clients other than the Lord Abbett Funds, but that business also benefits the Funds. The Board also noted that Lord Abbett, as disclosed in the prospectus of each Fund, has entered into revenue sharing arrangements with certain entities that distribute shares of the Lord Abbett Funds. The Board also took into consideration the investment research that Lord Abbett receives as a result of client brokerage transactions.

Alternative Arrangements.As to each Fund, the Board considered whether, instead of approving continuation of the Agreement, it might be in the best interests of the Fund to implement one or more alternative arrangements, such as continuing to employ Lord Abbett, but on different terms. After considering all of the relevant factors, the Board unanimously found that continuation of the Agreement was in the best interests of each Fund and its shareholders and voted unanimously to approve the continuation of the Agreement on behalf of each Fund. As to each Fund, in considering whether to approve the continuation of the Agreement, the Board did not identify any single factor as paramount or controlling. Individual Directors may have evaluated the information presented differently from one another, giving different weights to various factors. This summary does not discuss in detail all matters considered.
