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 the 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, 2012 through March 31, 2013).

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 10/1/12 – 3/31/13” 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 the 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.

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 consists of the following eight portfolios (separately, a “Fund” and collectively, the “Funds”) and their respective classes:

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

Short Duration, Intermediate, AMT Free and National are diversified as defined in the Act. High Yield, California, New Jersey and New York are non-diversified as defined in the Act. Short Duration has not issued Class B shares and only Intermediate and High Yield have issued Class P shares. High Yield’s Class B shares were fully redeemed on March 12, 2013. The Funds no longer issue Class B shares for purchase. The Funds’ Class P shares are closed to substantially all investors, with certain exceptions as set forth in the Funds’ prospectus.

The investment objective of each Fund (except for 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 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 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 B, C, F, I and P 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 B shares redeemed before the sixth anniversary of purchase; and Class C shares redeemed before the first anniversary of purchase. Class B shares will automatically convert to Class A shares on the 25^th day of the month (or, if the 25^th day is not a business day, the next business day thereafter) following the eighth anniversary of the day 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 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.

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 at the mean between the bid and asked prices on the basis of 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.
	Securities for which prices are not readily available are valued at fair value as determined by the Pricing Committee and approved by the Board. 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 fair value of portfolio investments. The Board or a designated committee thereof regularly reviews fair value determinations made by the Pricing Committee and employs 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 the Funds’ filed U.S. federal tax returns remains open for the fiscal years ended September 30, 2009 through September 30,

Notes to Financial Statements (unaudited)(continued)

	2012. The statutes of limitations on the Company’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.
(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. Class A, B, C, F and P shares bear their class-specific share of all expenses and fees relating to the Funds’ 12b-1 Distribution Plan.
(f)	Futures Contracts–Each Fund may purchase and sell futures contracts to enhance returns, to attempt to hedge some of its investment risk, or as a substitute position for 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. As of March 31, 2013, each Fund, except Short Duration, had open futures contracts.
(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 Statement 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 each 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.

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, 2013, as well as the average trust certificates outstanding for the six months ended March 31, 2013:

Fund	Liability for Trust Certificates		Interest Rate or Range of Interest Rates		Underlying Municipal Bonds Transferred to TOBs		Average Trust Certificates Outstanding
Short Duration	$	17,000,000		.13%	$	34,534,220	$	17,000,000

	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, 2013, 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 the secured borrowings for TOB transactions.
(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 of inputs is summarized in the three broad Levels listed below:

166

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).
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.

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, 2013 (as described in note 2(f)) to 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, 2013, 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) and net change in unrealized appreciation/depreciation on futures contracts are included in the Statements of Operations under the captions Net realized gain (loss) on investments and futures contracts and Net change in unrealized appreciation/depreciation on investments and futures contracts, respectively.

The following is a summary of U.S. Treasury futures contracts as of and during the six months ended March 31, 2013:

Notes to Financial Statements (unaudited)(continued)

In addition, Lord Abbett provides certain administrative services to each Fund pursuant to an Administrative Services Agreement in return for a fee at an annual rate of .04% of each Fund’s average daily net assets.

For the period February 1, 2013 through January 31, 2014, Lord Abbett has contractually agreed to waive all or a portion of its management fee and fund administration fee for Short Duration, Intermediate and AMT Free and reimburse each Fund’s expenses to the extent necessary to limit total net annual operating expenses for each class, excluding 12b-1 fees and interest related expenses, to an annual rate of .43%, .49% and .40%, respectively. This agreement may be terminated only by the Board.

For the twelve month period through January 31, 2013, Lord Abbett had contractually agreed to waive all or a portion of its management fee and fund administration fee for Short Duration, Intermediate and AMT Free and reimburse each Fund’s expenses to the extent necessary to limit total net annual operating expenses for each class, excluding 12b-1 fees and interest related expenses, to an annual rate of .41%, .47% and .35%, respectively.

12b-1 Distribution Plan
Each Fund has adopted a distribution plan with respect to Class A, B, C, F and P shares pursuant to Rule 12b-1 under the Act, which provides for the payment of ongoing distribution and service fees to Lord Abbett Distributor LLC (the “Distributor”), an affiliate of Lord Abbett. The fees are accrued daily at annual rates based upon each Fund’s average daily net assets as follows:

Fees	Class A		Class B		Class C(1)		Class F		Class P
Service		.15%		.25%		.25%		—		.25%
Distribution		.05%		.75%		.75%		.10%		.20%

⁽¹⁾ The Rule 12b-1 fee each Fund pays on Class C shares is a blended rate based on 1.00% of each Fund’s average daily net assets attributable to Class C shares held for less than one year and .80% (.25% service, .55% distribution) of each Fund’s average daily net assets attributable to Class C shares held for one year or more. All Class C shareholders of a Fund will bear Rule 12b-1 fees at the same rate.

Class I shares do not have a distribution plan.

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 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 accounting principles generally accepted in the United States of America. 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, 2013 and fiscal year ended September 30, 2012 were as follows:

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, 2013, the aggregate unrealized security gains and losses based on cost for U.S. federal income tax purposes were as follows:

	Tax Cost		Gross Unrealized Gain		Gross Unrealized Loss			Net Unrealized Gain
Short Duration		$2,542,615,776		$  50,529,919		$   (4,496,655	)		$  46,033,264

There were no purchases or sales of U.S. Government securities during the six months ended March 31, 2013.

6. DIRECTORS’ REMUNERATION

During the six months ended March 31, 2013, the Company’s officers and the two Directors who were associated with Lord Abbett did 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.

7. 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.

8. LINE OF CREDIT

On April 2, 2012, the Funds and certain other funds managed by Lord Abbett (the “participating funds”) entered into an unsecured revolving credit facility (“Facility”) with State Street Bank and Trust Company (“SSB”), to be used for temporary or emergency purposes as an additional source of liquidity to fund redemptions of investor shares. The Facility is renewed annually under terms that depend on market conditions at the time of the renewal. The amounts available under the Facility are (i) the lesser of either $250,000,000 or 33.33% of total assets per participating fund and (ii) $350,000,000 in the aggregate for all participating funds. The annual fee to maintain the Facility is .09% of the amount available under the Facility. Each participating fund pays its pro rata share based on the net assets of each participating fund. This amount is included in Other expenses on the Funds’ Statements of Operations. Any borrowings under this Facility will bear interest at current market rates as set forth in the credit agreement. As of March 31, 2013 there were no loans pursuant to this Facility, nor was the Facility utilized any time during the six months ended March 31, 2013.

175

Notes to Financial Statements (unaudited)(continued)

Effective April 1, 2013, the Funds and the participating funds entered into a short term extension of the Facility through June 30, 2013.

9. 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.

10. 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 inverse floaters than for shorter-term bonds. As a result, each Fund, to the extent it invests in long-term bonds and inverse floaters, is subject to such greater market risk.

Additional risks that could reduce each Fund’s performance or increase volatility include call risk, credit risk, derivatives risk, extension risk, governmental risk, industry risk, liquidity risk, market and portfolio management risks, state and territory risks, and taxability risk. 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 invests a significant portion of its assets in such bonds. AMT Free and National may invest up to 35% and all other Funds (excluding High Yield) may invest up to 20% of their respective 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 the Fund. Junk bonds are considered predominantly speculative by traditional investment standards. In addition, the market for lower rated municipal bonds generally is less liquid than the market for higher rated bonds, subjecting them to greater price fluctuations which could result in losses.

Each of 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, each 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, AMT Free, National, and 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 (except AMT Free and High Yield) may invest up to 20% of its net assets in private activity bonds (sometimes called “AMT paper”). AMT Free may not invest in AMT paper. High Yield may invest up to 100% of its net assets in AMT paper. The credit quality of such bonds usually is directly related to the credit standing of the private user of the facilities.

176

Notes to Financial Statements (unaudited)(continued)

Each Fund may invest no more than 20% of its net assets in TOB Residuals, except High Yield, which may invest up to 100% of its net assets 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 (“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, inverse floaters and similar transactions. These instruments may be leveraged so that small changes may produce disproportionate and substantial losses to the 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.

Approval of Advisory Contract

The Board of Directors of the Company, including all of the Directors who are not interested persons of the Company or Lord, Abbett & Co. LLC (“Lord Abbett”), annually considers whether to approve the continuation of the existing management agreement between the Fund and Lord Abbett. In connection with its most recent approval, the Board reviewed materials relating specifically to the management agreement, as well as numerous materials received throughout the course of the year, including information about the Fund’s investment performance compared to the performance of its benchmark. Before making its decision as to each Fund, the Board had the opportunity to ask questions and request further information, taking into account its familiarity with Lord Abbett gained through its meetings and discussions. These meetings and discussions included the examination of the portfolio management teams 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 materials received by the Board as to each Fund included, but were not limited to: (1) information provided by Lipper Inc. regarding the investment performance of the Fund compared to the investment performance of a group of funds within the same investment classification/objective (the “performance universe”) and the investment performance of an appropriate benchmark; (2) information on the expense ratios, contractual and effective management fee rates, and other expense components for the Fund and one or more groups of funds with similar objectives and of similar size (the “peer group”); (3) information provided by Lord Abbett on the projected expense ratios, management fee rates, and other expense components for the Fund; (4) sales and redemption information for the Fund; (5) information regarding Lord Abbett’s financial condition; (6) an analysis of the relative profitability of the management agreement to Lord Abbett; (7) information provided by Lord Abbett regarding the investment management fees Lord Abbett receives from its other advisory clients maintaining accounts with a similar investment strategy as the Fund; (8) information regarding the distribution arrangements of the Fund; and (9) information regarding the personnel and other resources devoted by Lord Abbett to managing the Fund.

Investment Management Services Generally. The Board considered the investment management services provided by Lord Abbett to each Fund, including investment research, portfolio management, and trading, and Lord Abbett’s commitment to compliance with all relevant 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 resulting 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 the Fund and other Lord Abbett Funds, on the one hand, and the services provided to other clients, on the other.

Investment Performance. The Board reviewed each Fund’s investment performance in relation to that of the relevant performance universes, in each case as of various periods ended September 30, 2012. As to each of Short Duration Tax Free Fund, Intermediate Tax Free Fund, AMT Free Municipal Bond Fund, and National Tax Free Fund, the Board observed that the investment performance of the Class A shares was above the median of the performance universe for each period. As to High Yield Municipal Bond Fund, the Board observed that the performance of the Class A shares was above the median of the performance universe for the nine-month and one-year periods and below the median for the three-year and five-year periods. As to each of California Tax Free Income Fund and New Jersey Tax Free Fund, the Board observed that the performance of the Class A shares was

183

above the median of the performance universe for the nine-month, one-year, and three-year periods and below the median for the five-year and ten-year periods. As to New York Tax Free Income Fund, the Board observed that the performance of the Class A shares was above the median of the performance universe for the nine-month, one-year, three-year, and five-year periods and below the median for the ten-year period.

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. Among other things, the Board considered the size, experience, and turnover of Lord Abbett’s investment management staff, Lord Abbett’s investment methodology and philosophy, and Lord Abbett’s approach to recruiting, training, and retaining investment management personnel.

Nature and Quality of Other Services. The Board considered the nature, quality, costs, and extent of compliance, administrative, and other services performed by Lord Abbett and Lord Abbett Distributor LLC (“Distributor”) 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 class of shares of each Fund and the expense levels of one or more corresponding peer groups. The Board considered the fiscal periods on which the peer group comparisons were based, and noted that the fiscal years of many funds in each Fund’s peer group did not coincide with the Fund’s fiscal year. It also considered the projected expense levels of each Fund and how those levels would relate to those of the peer group and the amount and nature of the fees paid by shareholders. As to Short Duration Tax Free Fund, the Board observed that the expense ratios were generally below or the same as medians of the peer group. As to Intermediate Tax Free Fund, the Board observed that some of the expense ratios were below and others were above the medians of the peer group. In addition, as to Intermediate Tax Free Fund, the Board noted that Lord Abbett had agreed to a new fee schedule to the Management Agreement, effective February 1, 2013. As to AMT Free Municipal Bond Fund, the Board observed that the expense ratios were below the medians of the peer group. As to National Tax Free Fund, the Board observed that the expense ratios were slightly above the medians of the peer group. As to High Yield Municipal Bond Fund, the Board observed that the expense ratios generally were below or the same as the medians of the peer group, other than the expense ratio of Class P shares. As to each of California Tax Free Fund and New York Tax Free Fund, the Board observed that the expense ratios were below the medians of the peer group, other than the expense ratio of Class F shares. As to New Jersey Tax Free Fund, the Board observed that the expense ratios were the same as or slightly below the medians of the peer groups.

Profitability. As to each Fund, the Board considered the level of Lord Abbett’s profits in managing the Fund, including a review of Lord Abbett’s methodology for allocating its costs to its management of the Fund. The Board concluded that the allocation methodology had a reasonable basis and was appropriate. It considered any profits realized by Lord Abbett in connection with the operation of each Fund, including the fee that Lord Abbett receives from the Fund for providing administrative services to the Fund, and whether the amount of profit was fair for the management of the Fund. The Board also considered the profits realized from other business segments of Lord Abbett, which may benefit from or be related to the Fund’s business. The Board considered Lord Abbett’s profit margins in comparison with available industry data, both accounting for and ignoring marketing and distribution expenses, and how those profit margins could affect Lord Abbett’s ability to recruit and retain investment personnel. The Board recognized that Lord Abbett’s

184

profitability was a factor in enabling it to attract and retain qualified investment management personnel to provide services to the Fund. The Board concluded that Lord Abbett’s profitability as to each Fund was not excessive.

Economies of Scale. As to each Fund, the Board considered whether there had been any economies of scale in managing the Fund, whether the Fund had appropriately benefited from any such economies of scale, and whether there was potential for realization of any further economies of scale. The Board concluded that each existing management fee schedule, with its breakpoint or breakpoints in the level of the management fee, adequately addressed any economies of scale in managing the applicable Fund.

Other Benefits to Lord Abbett. As to each Fund, the Board considered the character and amount of fees paid by the Fund and the Fund’s shareholders to Lord Abbett and Distributor for services other than investment advisory services. 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 the Fund. The Board observed that 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 from the Funds, and receives a portion of the sales charges on sales and redemptions of some classes of shares. 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 prospectuses of the Funds, has entered into revenue sharing arrangements with certain entities that distribute shares of the Funds.

Alternative Arrangements. As to each Fund, the Board considered whether, instead of approving continuation of the management 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 existing management agreements was in the best interests of each Fund and its shareholders and voted unanimously to approve the continuation of the management agreements. In considering whether to approve the continuation of the management agreement, the Board did not identify any single factor as paramount or controlling. This summary does not discuss in detail all matters considered.
