ANNUAL REPORT

July 21, 2021

This report provides management’s discussion of fund performance for the AB Municipal Income Fund: AB California Portfolio, AB High Income Municipal Portfolio, AB National Portfolio and AB New York Portfolio for the annual reporting period ended May 31, 2021.

The investment objective of the California, National and New York Portfolios is to earn the highest level of current income, exempt from federal income tax—and in the case of the California and New York Portfolios, state taxation of the respective state—that is available without assuming what the Adviser considers to be undue risk to principal or income. The investment objective of the High Income Municipal Portfolio is to earn the highest level of current income, exempt from federal income tax, that is available, consistent with what the Adviser considers to be an appropriate level of risk.

INVESTMENT RESULTS

The preceding tables show performance for each Portfolio compared to its benchmark, the Bloomberg Barclays Municipal Bond Index, for the six- and 12-month periods ended May 31, 2021.

All share classes of the Portfolios outperformed the benchmark for both periods, before sales charges. During both periods, an overweight to municipal credit contributed, relative to the benchmark. Inflation hedges also contributed, as inflation expectations increased.

California Portfolio: During both periods, security selection within the miscellaneous-revenue sector contributed, while selection in multi-family housing detracted.

High Income Portfolio: While the benchmark is fully invested in investment-grade securities, the Portfolio invests in below-investment-grade securities, which was beneficial over both periods. During both periods, security selection within the special tax sector contributed, while selection in multi-family housing detracted.

National Portfolio: During both periods, security selection within the state general obligation (“GO”) sector contributed, while selection in multi-family housing detracted.

abfunds.com AB MUNICIPAL INCOME FUND    ^|    3

New York Portfolio: During both periods, security selection within the toll roads/transit sector detracted. For the 12-month period, security selection in special tax contributed. During the six-month period, security selection in private higher education contributed.

All Portfolios utilized derivatives in the form of inflation Consumer Price Index (“CPI”) swaps and interest rate swaps for hedging purposes. During both periods, inflation CPI swaps added to absolute returns for all Portfolios. During the six-month period, interest rate swaps detracted for the High Income and National Portfolios, but had an immaterial impact for the California and New York Portfolios. During the 12-month period, interest rate swaps detracted for the High Income and New York Portfolios, but had an immaterial impact for the California and National Portfolios.

The High Income Municipal Portfolio also utilized credit default swaps for investment purposes, which detracted for both periods.

MARKET REVIEW AND INVESTMENT STRATEGY

During the 12-month period ended May 31, 2021, the municipal market continued its rather swift recovery following the single worst month of outflows in municipal market history in March 2020, when investors ran to cash, prompting $42.5 billion dollars in outflows from municipal bond mutual funds. The municipal market stabilized shortly after this historic sell-off and finished the year with eight consecutive months of inflows, totaling $40.9 billion for 2020, as investors sought relatively attractive after-tax yields. The asset class showed a tremendous amount of resiliency, bouncing back from its March drawdown to post a return of 5.2% in 2020.

In the first five months of 2021, the US economy moved closer to a full reopening and equity markets continued to rally, while interest rates and inflation expectations rose in anticipation of stronger growth ahead. The yield on the 10-year US Treasury rose 68 basis points (“b.p.”) in 2021, to 1.60% as of May 31, 2021. The bright side for muni investors is that the 10-year AAA municipal bond yield rose just 28 b.p. to 0.99% in the same period—less than half as much as the 10-year Treasury. Through May, municipals posted positive absolute returns of 0.78%, and higher returns, relative to other fixed-income asset classes, such as US Treasuries and US investment-grade corporates, which both posted negative returns. The two main catalysts behind the municipal market’s outperformance were strong investor demand and generally improving fundamentals among municipal issuers. During the first five months of 2021, investors poured $50 billion into the market, on pace for a new calendar-year record, and marked 12 consecutive months of inflows following the dramatic sell-off in municipals associated with the 2020 pandemic.

Demand for income was very apparent during the first five months of the year as BBB-rated and high-yield credit spreads compressed—64 b.p. and 85 b.p., respectively—leading to outperformance relative to high-grade

counterparts. Investor concerns around issuer credit fundamentals were calmed by a combination of much better-than-expected tax revenue collections, as well as a bevy of stimulus for municipal issuers from the federal government. Municipalities benefited from three separate stimulus packages. First, the CARES Act supplied a much needed $347 billion to issuers, and this has since been supplemented by a package passed in late December 2020, which had $167 billion appropriated for various municipal sectors. Finally, the American Rescue Plan Act of 2021 supplied $649 billion for issuers. Public rating agencies reacted to the positive credit trends, as evidenced by the S&P 500’s removal of several noteworthy negative outlooks on large sectors, including state and local government, school districts, mass transit, airports, toll roads and specific issuers such as the state of Illinois.

The Portfolios may purchase municipal securities that are insured under policies issued by certain insurance companies. In the past, insured municipal securities typically received a higher credit rating, which meant that the issuer of the securities paid a lower interest rate. As a result of declines in the credit quality and associated downgrades of most bond insurers, insurance has less value than it did in the past. The market now values insured municipal securities primarily based on the credit quality of the issuer of the security, with little value given to the insurance feature. In purchasing such insured securities, the Adviser evaluates the risk and return of municipal securities through its own research. If an insurance company’s rating is downgraded or the company becomes insolvent, the prices of municipal securities insured by the insurance company may decline.

INVESTMENT POLICIES

Each of the California, National and New York Portfolios pursues its objective by investing principally in high-yielding, predominantly investment-grade municipal securities. The High Income Municipal Portfolio pursues its objective by investing principally in high-yielding municipal securities that may be noninvestment grade or investment grade.

(continued on next page)

abfunds.com AB MUNICIPAL INCOME FUND    ^|    5

Each Portfolio invests, under normal circumstances, at least 80% of its net assets in municipal securities that pay interest that is exempt from federal income tax. These securities may pay interest that is subject to the federal alternative minimum tax for certain taxpayers. Each of the Portfolios that invests in a named state pursues its objective by investing at least 80% of its net assets in municipal securities issued by the named state or municipal securities with interest that is otherwise exempt from the named state’s income tax. The National Portfolio may invest 25% or more of its net assets in a single state.

The California, National and New York Portfolios may also invest in forward commitments; tender option bonds (“TOBs”); zero-coupon municipal securities; and variable-, floating- and inverse-floating-rate municipal securities; and derivatives, such as options, futures contracts, forwards and swaps.

The High Income Municipal Portfolio may invest without limit in lower-rated securities (“junk bonds”), which may include securities having the lowest rating, and in unrated securities that, in the Adviser’s judgment, would be lower-rated securities if rated. The Portfolio may invest in fixed-income securities with any maturity or duration. The Portfolio will seek to increase income for shareholders by investing in longer-maturity bonds. Consistent with its objective of seeking a higher level of income, the Portfolio may experience greater volatility and a higher risk of loss of principal than other municipal funds. The Portfolio may also invest in forward commitments; zero-coupon municipal securities; and variable-, floating- and inverse-floating-rate municipal securities; and certain types of mortgage-related securities. The Portfolio may invest in derivatives, such as options, futures contracts, forwards and swaps. The Portfolio may make short sales of securities or maintain a short position and may use other investment techniques. The Portfolio may use leverage for investment purposes to increase income through the use of TOBs and derivative instruments, such as interest rate swaps.

DISCLOSURES AND RISKS

Benchmark Disclosure

The Bloomberg Barclays Municipal Bond Index is unmanaged and does not reflect fees and expenses associated with the active management of a mutual fund portfolio. The Bloomberg Barclays Municipal Bond Index represents the performance of the long-term tax-exempt bond market consisting of investment-grade bonds. An investor cannot invest directly in an index, and its results are not indicative of the performance for any specific investment, including the Portfolios.

A Word About Risk

Market Risk: The value of the Portfolios’ assets will fluctuate as the bond market fluctuates. The value of the Portfolios’ investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, including public health crises (including the occurrence of a contagious disease or illness), that affect large portions of the market.

Credit Risk: An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Below Investment-Grade Securities Risk (High Income Municipal Portfolio): Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) tend to have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest-rate sensitivity and negative performance of the junk bond market generally and may be more difficult to trade than other types of securities.

Municipal Market Risk: This is the risk that special factors may adversely affect the value of municipal securities and have a significant effect on the yield or value of the Portfolios’ investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, or the rights of investors in these securities. To the extent that the Portfolios invest more of their assets in a particular state’s municipal securities, the Portfolios may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions,

abfunds.com AB MUNICIPAL INCOME FUND    ^|    7

DISCLOSURES AND RISKS (continued)

terrorism public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. For example, the novel coronavirus (COVID-19) pandemic has significantly stressed the financial resources of many issuers of municipal securities, which could impair any such issuer’s ability to meet its financial obligations when due and adversely impact the value of its securities held by the Portfolios. As the full effects of the COVID-19 pandemic on state and local economies and on issuers of municipal securities are still uncertain, the financial difficulties of issuers of municipal securities may continue or worsen, adversely affecting the performance of the Portfolios. The Portfolios’ investments in certain municipal securities with principal and interest payments that are made from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

Congress has previously considered making changes to the municipal securities provisions of the Internal Revenue Code that could change the US federal income tax treatment of certain types of municipal securities.

The Portfolios invest from time to time in municipal securities of issuers in Puerto Rico or other US territories and their governmental agencies and municipalities, which are exempt from federal, state, and, where applicable, local income taxes. These municipal securities may have more risks than those of other US issuers of municipal securities. Like many US states and municipalities, Puerto Rico experienced a significant downturn during the 2007-2009 recession. Puerto Rico’s downturn was particularly severe, and Puerto Rico continues to face a very challenging economic and fiscal environment, including as a result of the COVID-19 pandemic. If the general economic situation in Puerto Rico continues to persist or worsens, the volatility and credit quality of Puerto Rican municipal securities could continue to be adversely affected, and the market for such securities may experience continued volatility.

Tax Risk: There is no guarantee that the income on the Portfolios’ municipal securities will be exempt from regular federal, and if applicable, state income taxes. From time to time, the US government and the US Congress consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Portfolios by increasing taxes on that income. In such event, the Portfolios’ net asset value (“NAV”) could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to

8    ^|    AB MUNICIPAL INCOME FUND abfunds.com

DISCLOSURES AND RISKS (continued)

approximately the yield of comparable taxable bonds. Actions or anticipated actions affecting the tax-exempt status of municipal bonds could also result in significant shareholder redemptions of Portfolio shares as investors anticipate adverse effects on the Portfolios or seek higher yields to offset the potential loss of the tax deduction. As a result, the Portfolios would be required to maintain higher levels of cash to meet the redemptions, which would negatively affect the Portfolios’ yield.

Interest-Rate Risk: Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new investments. Interest-rate risk is generally greater for fixed-income securities with longer maturities or durations. The current historically low interest rate environment heightens the risks associated with rising interest rates.

Duration Risk: Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Inflation Risk: This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Portfolios’ assets can decline as can the value of the Portfolios’ distributions. This risk is significantly greater for fixed-income securities with longer maturities.

Leverage Risk (High Income Municipal Portfolio): To the extent the Portfolio uses leveraging techniques, such as TOBs, its NAV may be more volatile because leverage tends to exaggerate the effect of changes in interest rates and any increase or decrease in the value of the Portfolio’s investments.

Illiquid Investments Risk: Illiquid investments risk exists when certain investments are or become difficult to purchase or sell. Difficulty in selling such investments may result in sales at disadvantageous prices affecting the value of your investment in the Portfolios. Causes of illiquid investments risk may include low trading volumes, large positions and heavy redemptions of Portfolio shares. Illiquid investments risk may be higher in a rising interest-rate environment, when the value and liquidity of fixed-income securities generally decline. Municipal securities may have more illiquid investments risk than other fixed-income securities because they trade less frequently and the market for municipal securities is generally smaller than many other markets.

abfunds.com AB MUNICIPAL INCOME FUND    ^|    9

DISCLOSURES AND RISKS (continued)

Derivatives Risk: Derivatives may be difficult to price or unwind and leveraged so that small changes may produce disproportionate losses for the Portfolios. Derivatives, especially over-the-counter derivatives, are also subject to counterparty risk.

Management Risk: The Portfolios are subject to management risk because they are actively managed investment funds. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.

These risks are fully discussed in the Portfolios’ prospectus. As with all investments, you may lose money by investing in the Portfolios.

An Important Note About Historical Performance

The investment return and principal value of an investment in the Portfolios will fluctuate, so that shares, when redeemed, may be worth more or less than their original cost. Performance shown in this report represents past performance and does not guarantee future results. Current performance may be lower or higher than the performance information shown. You may obtain performance information current to the most recent month-end by visiting www.abfunds.com. Class B shares are no longer being offered. Effective November 7, 2019, all outstanding Class B shares were converted to Class A shares. Please see Note A for more information.

All fees and expenses related to the operation of the Portfolios have been deducted. NAV returns do not reflect sales charges; if sales charges were reflected, the Portfolios’ quoted performance would be lower. SEC returns and the Portfolios’ returns shown in the line graphs reflect the applicable sales charges for each share class: a 3% maximum front-end sales charge for Class A shares and a 1% 1-year contingent deferred sales charge for Class C shares. Returns for the different share classes will vary due to their different expenses associated with each class. Performance assumes reinvestment of distributions and does not account for taxes.

EXPENSE EXAMPLE

(unaudited)

As a shareholder of a Portfolio, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, contingent deferred sales charges on redemptions and (2) ongoing costs, including management fees; distribution (12b-1) fees; and other Portfolio expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Portfolio 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 as indicated below.

Actual Expenses

The first line of the table below 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 entitled “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on a Portfolio’s actual expense ratio and an assumed annual rate of return of 5% before expenses, which is not the Portfolio’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 Portfolio and other funds by comparing this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds.

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), or contingent deferred sales charges on redemptions. 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.

BOND RATING SUMMARY¹

May 31, 2021 (unaudited)

1 All data are as of May 31, 2021. The Portfolio’s quality rating breakdown is expressed as a percentage of the Portfolio’s total investments in municipal securities and may vary over time. The Portfolio also enters into derivative transactions, which may be used for hedging or investment purposes (see “Portfolio of Investments” section of the report for additional details). The quality ratings are determined by using the S&P Global Ratings (“S&P”), Moody’s Investors Services, Inc. (“Moody’s”) and Fitch Ratings, Ltd. (“Fitch”). The Portfolio considers the credit ratings issued by S&P, Moody’s and Fitch and uses the highest rating issued by the agencies. These ratings are a measure of the quality and safety of a bond or portfolio, based on the issuer’s financial condition. AAA is the highest (best) and D is the lowest (worst). If applicable, the pre-refunded category includes bonds which are secured by U.S. Government securities and therefore are deemed high-quality investment grade by the Adviser. If applicable, Not Applicable (N/A) includes non-creditworthy investments; such as, equities, currency contracts, futures and options. If applicable, the Not Rated category includes bonds that are not rated by a nationally recognized statistical rating organization. The Adviser evaluates the creditworthiness of non-rated securities based on a number of factors including, but not limited to, cash flows, enterprise value and economic environment.

NOTES TO FINANCIAL STATEMENTS

NOTE A

Significant Accounting Policies

AB Municipal Income Fund, Inc. (the “Fund”) is registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund, which is a Maryland corporation, operates as a series company currently comprised of the diversified AB California Portfolio, AB High Income Municipal Portfolio, AB National Portfolio and AB New York Portfolio (the “Portfolios”). Each series is considered to be a separate entity for financial reporting and tax purposes. The AB California Portfolio, AB National Portfolio and AB New York Portfolio offer Class A, Class C and Advisor Class shares. The AB High Income Municipal Portfolio offers Class A, Class C, Advisor Class and Class Z shares. Class B and Class T shares have been authorized but currently are not offered. Class Z shares have been authorized but currently are not being offered for AB California Portfolio, AB National Portfolio and AB New York Portfolio. Effective August 2, 2019, sales of Class B shares were suspended. On November 7, 2019, all remaining outstanding Class B shares of the Portfolios were converted to Class A shares. Class A shares are sold with a front-end sales charge of up to 3% for purchases up to $500,000; purchases of $500,000 or more are not subject to a sales charge. With respect to purchases of $500,000 or more, Class A shares redeemed within one year of purchase may be subject to a contingent deferred sales charge of 1%. Class C shares are subject to a contingent deferred sales charge of 1% on redemptions made within the first year after purchase, and 0% after the first year of purchase. Effective May 31, 2021, Class C shares will automatically convert to Class A shares eight years after the end of the calendar month of purchase. Prior to May 31, 2021, Class C shares automatically converted to Class A shares ten years after the end of the calendar month of purchase. Advisor Class shares are sold without any initial or contingent deferred sales charge and are not subject to ongoing distribution expenses. All six classes of shares have identical voting, dividend, liquidation and other rights, except that the classes bear different distribution and transfer agency expenses. Each class has exclusive voting rights with respect to its distribution plan. The financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”), which require management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and amounts of income and expenses during the reporting period. Actual results could differ from those estimates. Each Portfolio is an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following is a summary of significant accounting policies followed by the Portfolios.

NOTES TO FINANCIAL STATEMENTS (continued)

1. Security Valuation

Portfolio securities are valued at their current market value determined on the basis of market quotations or, if market quotations are not readily available or are deemed unreliable, at “fair value” as determined in accordance with procedures established by and under the general supervision of the Fund’s Board of Directors (the “Board”).

In general, the market values of securities which are readily available and deemed reliable are determined as follows: securities listed on a national securities exchange (other than securities listed on the NASDAQ Stock Market, Inc. (“NASDAQ”)) or on a foreign securities exchange are valued at the last sale price at the close of the exchange or foreign securities exchange. If there has been no sale on such day, the securities are valued at the last traded price from the previous day. Securities listed on more than one exchange are valued by reference to the principal exchange on which the securities are traded; securities listed only on NASDAQ are valued in accordance with the NASDAQ Official Closing Price; listed or over the counter (“OTC”) market put or call options are valued at the mid level between the current bid and ask prices. If either a current bid or current ask price is unavailable, AllianceBernstein L.P. (the “Adviser”) will have discretion to determine the best valuation (e.g., last trade price in the case of listed options); open futures are valued using the closing settlement price or, in the absence of such a price, the most recent quoted bid price. If there are no quotations available for the day of valuation, the last available closing settlement price is used; U.S. Government securities and any other debt instruments having 60 days or less remaining until maturity are generally valued at market by an independent pricing vendor, if a market price is available. If a market price is not available, the securities are valued at amortized cost. This methodology is commonly used for short term securities that have an original maturity of 60 days or less, as well as short term securities that had an original term to maturity that exceeded 60 days. In instances when amortized cost is utilized, the Valuation Committee (the “Committee”) must reasonably conclude that the utilization of amortized cost is approximately the same as the fair value of the security. Factors the Committee will consider include, but are not limited to, an impairment of the creditworthiness of the issuer or material changes in interest rates. Fixed-income securities, including mortgage-backed and asset-backed securities, may be valued on the basis of prices provided by a pricing service or at a price obtained from one or more of the major broker-dealers. In cases where broker-dealer quotes are obtained, the Adviser may establish procedures whereby changes in market yields or spreads are used to adjust, on a daily basis, a recently obtained quoted price on a security. Swaps and other derivatives are valued daily, primarily using independent pricing services, independent pricing models using market inputs, as well as third party broker-dealers or counterparties.

abfunds.com AB MUNICIPAL INCOME FUND    ^|    159

NOTES TO FINANCIAL STATEMENTS (continued)

Open-end mutual funds are valued at the closing net asset value per share, while exchange traded funds are valued at the closing market price per share.

Securities for which market quotations are not readily available (including restricted securities) or are deemed unreliable are valued at fair value as deemed appropriate by the Adviser. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, analysis of the issuer’s financial statements or other available documents. In addition, the Portfolios may use fair value pricing for securities primarily traded in non-U.S. markets because most foreign markets close well before the Portfolios value their securities at 4:00 p.m., Eastern Time. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim and may materially affect the value of those securities. To account for this, the Portfolios generally value many of their foreign equity securities using fair value prices based on third party vendor modeling tools to the extent available.

2. Fair Value Measurements

In accordance with U.S. GAAP regarding fair value measurements, fair value is defined as the price that the Portfolios would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. U.S. GAAP establishes a framework for measuring fair value, and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability (including those valued based on their market values as described in Note A.1 above). Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Portfolios. Unobservable inputs reflect the Portfolios’ own assumptions about the assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances. Each investment is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three-tier hierarchy of inputs is summarized below.

• Level 1—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.)

• Level 3—significant unobservable inputs (including the Portfolios’ own assumptions in determining the fair value of investments)

160    ^|    AB MUNICIPAL INCOME FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

The fair value of debt instruments, such as bonds, and over-the-counter derivatives is generally based on market price quotations, recently executed market transactions (where observable) or industry recognized modeling techniques and are generally classified as Level 2. Pricing vendor inputs to Level 2 valuations may include quoted prices for similar investments in active markets, interest rate curves, coupon rates, currency rates, yield curves, option adjusted spreads, default rates, credit spreads and other unique security features in order to estimate the relevant cash flows which are then discounted to calculate fair values. If these inputs are unobservable and significant to the fair value, these investments will be classified as Level 3.

Other fixed income investments, including non-U.S. government and corporate debt, are generally valued using quoted market prices, if available, which are typically impacted by current interest rates, maturity dates and any perceived credit risk of the issuer. Additionally, in the absence of quoted market prices, these inputs are used by pricing vendors to derive a valuation based upon industry or proprietary models which incorporate issuer specific data with relevant yield/spread comparisons with more widely quoted bonds with similar key characteristics. Those investments for which there are observable inputs are classified as Level 2. Where the inputs are not observable, the investments are classified as Level 3.

The following tables summarize the valuation of the Portfolios’ investments by the above fair value hierarchy levels as of May 31, 2021:

(a) Other financial instruments are derivative instruments, such as futures, forwards and swaps, which are valued at the unrealized appreciation/(depreciation) on the instrument. Other financial instruments may also include swaps with upfront premiums, options written and swaptions written which are valued at market value.

(b) Only variation margin receivable/(payable) at period end is reported within the statement of assets and liabilities. This amount reflects cumulative unrealized appreciation/(depreciation) on futures and centrally cleared swaps as reported in the portfolio of investments. Where applicable, centrally cleared swaps with upfront premiums are presented here at market value.

(c) The Portfolio may hold liabilities in which the fair value approximates the carrying amount for financial statement purposes.

3. Taxes

It is each Portfolio’s policy to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its investment company taxable income and net realized gains, if any, to shareholders. Therefore, no provisions for federal income or excise taxes are required.

In accordance with U.S. GAAP requirements regarding accounting for uncertainties in income taxes, management has analyzed the Portfolios’ tax positions taken or expected to be taken on federal and state income tax returns for all open tax years (the current and the prior three tax years) and has concluded that no provision for income tax is required in the Portfolios’ financial statements.

164    ^|    AB MUNICIPAL INCOME FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

4. Investment Income and Investment Transactions

Dividend income is recorded on the ex-dividend date or as soon as the Portfolios are informed of the dividend. Interest income is accrued daily. Investment transactions are accounted for on the date the securities are purchased or sold. Investment gains or losses are determined on the identified cost basis. The Portfolios amortize premiums and accrete original issue and market discounts as adjustments to interest income. The Portfolio accounts for distributions received from REIT investments or from regulated investment companies as dividend income, realized gain, or return of capital based on information provided by the REIT or the investment company.

5. Class Allocations

All income earned and expenses incurred by the Portfolios are borne on a pro-rata basis by each settled class of shares, based on the proportionate interest in each Portfolio represented by the net assets of such class, except for class specific expenses which are allocated to the respective class. Expenses of the Fund are charged proportionately to the Portfolios or based on other appropriate methods. Realized and unrealized gains and losses are allocated among the various share classes based on respective net assets.

6. Dividends and Distributions

Dividends and distributions to shareholders, if any, are recorded on the ex-dividend date. Income dividends and capital gains distributions are determined in accordance with federal tax regulations and may differ from those determined in accordance with U.S. GAAP. To the extent these differences are permanent, such amounts are reclassified within the capital accounts based on their federal tax basis treatment; temporary differences do not require such reclassification.

NOTE B

Advisory Fee and Other Transactions with Affiliates

Under the terms of the investment advisory agreement, the Portfolios pay the Adviser at the annual rates as follows:

	Average Daily Net Assets
Portfolio	First $2.5 Billion			Next $2.5 Billion			In Excess of $5 Billion
AB California		.45	%		.40	%		.35	%
AB High Income Municipal		.50	%		.45	%		.40	%
AB National		.45	%		.40	%		.35	%

Such fees are accrued daily and paid monthly.

abfunds.com AB MUNICIPAL INCOME FUND    ^|    165

NOTES TO FINANCIAL STATEMENTS (continued)

The Adviser has agreed to waive its fees and bear certain expenses to the extent necessary to limit the total operating expenses (excluding interest expense, brokerage commissions and other transaction costs, taxes and extraordinary expenses) on an annual basis (the “Expense Caps”) as follows:

Portfolio	Class A			Class C			Advisor Class			Class Z
AB California		.75	%		1.50	%		.50	%		N/A
AB High Income Municipal		.80	%		1.55	%		.55	%		.55	%
AB National		.75	%		1.50	%		.50	%		N/A
AB New York		.75	%		1.50	%		.50	%		N/A

This contractual agreement extends through September 30, 2021, for all Portfolios and may be extended by the Adviser for additional one year terms.

For the year ended May 31, 2021, such reimbursements amounted to $232,143, $0, $468,694 and $326,507 for AB California, AB High Income Municipal, AB National and AB New York Portfolios, respectively.

Pursuant to the investment advisory agreement, each Portfolio may reimburse the Adviser for certain legal and accounting services provided to each Portfolio by the Adviser. For the year ended May 31, 2021, the reimbursement for such services amounted to $93,175, $107,899, $93,175 and $96,571 for AB California, AB High Income Municipal, AB National and AB New York Portfolios, respectively.

The Portfolios compensate AllianceBernstein Investor Services, Inc. (“ABIS”), a wholly-owned subsidiary of the Adviser, under a Transfer Agency Agreement for providing personnel and facilities to perform transfer agency services for the Portfolios. ABIS may make payments to intermediaries that provide omnibus account services, sub-accounting services and/or networking services. Such compensation retained by ABIS amounted to: AB California Portfolio, $65,678; AB High Income Municipal Portfolio, $228,304; AB National Portfolio, $179,126 and AB New York Portfolio, $67,171 for the year ended May 31, 2021.

AllianceBernstein Investments, Inc. (the “Distributor”), a wholly-owned subsidiary of the Adviser, serves as the distributor of the Portfolios’ shares. The Distributor has advised the Portfolios that it has retained front-end sales charges from the sale of Class A shares and received contingent deferred sales charges imposed upon redemptions by shareholders of

The Portfolios may invest in AB Government Money Market Portfolio (the “Government Money Market Portfolio”) which has a contractual annual advisory fee rate of .20% of the portfolio’s average daily net assets and bears its own expenses. The Adviser has contractually agreed to waive .10% of the advisory fee of Government Money Market Portfolio (resulting in a net advisory fee of .10%) until August 31, 2022. In connection with the investment by the Portfolios in Government Money Market Portfolio, the Adviser has contractually agreed to waive its advisory fee from the Portfolios in an amount equal to each Portfolio’s pro rata share of the effective advisory fee of Government Money Market Portfolio, as borne indirectly by the Portfolios as an acquired fund fee and expense. For the year ended May 31, 2021, such waivers amounted to:

Portfolio	Amount
AB California	$	26,335
AB High Income Municipal		73,249
AB National		45,368
AB New York		11,758

A summary of the Portfolios’ transactions in shares of the Government Money Market Portfolio for the year ended May 31, 2021 is as follows:

During the second quarter of 2018, AXA S.A. (“AXA”), a French holding company for the AXA Group, completed the sale of a minority stake in its subsidiary, AXA Equitable Holdings, Inc. (now named Equitable Holdings, Inc.) (“Equitable”), through an initial public offering. Equitable is the holding company for a diverse group of financial services companies, including an approximate 65% economic interest in the Adviser and a 100% interest in

NOTES TO FINANCIAL STATEMENTS (continued)

AllianceBernstein Corporation, the general partner of the Adviser. Since the initial sale, AXA has completed additional offerings (and related transactions). As a result, as of May 20, 2021, AXA no longer owns shares of Equitable.

Sales that were completed on November 13, 2019 resulted in the indirect transfer of a “controlling block” of voting securities of the Adviser (a “Change of Control Event”) and may have been deemed to have been an “assignment” causing a termination of the Fund’s investment advisory and administration agreements. In order to ensure that investment advisory and administration services could continue uninterrupted in the event of a Change of Control Event, the Board previously approved new investment advisory and administration agreements with the Adviser, and shareholders of the Fund subsequently approved the new investment advisory agreement. These agreements became effective on November 13, 2019.

NOTE C

Distribution Services Agreement

The Portfolios have adopted a Distribution Services Agreement (the “Agreement”) pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the Agreement, the Portfolios pay distribution and servicing fees to the Distributor at an annual rate of up to .30% of the Portfolios’ average daily net assets attributable to Class A shares and 1% of the Portfolios’ average daily net assets attributable to Class C shares. Payments under the Agreement in respect of Class A shares are currently limited to an annual rate of .25% of Class A shares’ average daily net assets. There are no distribution and servicing fees on the Advisor Class shares. The fees are accrued daily and paid monthly. The Agreement provides that the Distributor will use such payments in their entirety for distribution assistance and promotional activities. Since the commencement of the Portfolios’ operations, the distributor has incurred expenses in excess of the distribution costs reimbursed by each Portfolio as follows:

Portfolio	Class C
AB California	$	7,596,853

1. Derivative Financial Instruments

Each Portfolio may use derivatives in an effort to earn income and enhance returns, to replace more traditional direct investments, to obtain exposure to otherwise inaccessible markets (collectively, “investment purposes”), or to hedge or adjust the risk profile of its portfolio.

The principal type of derivative utilized by the Portfolios, as well as the methods in which they may be used are:

• Swaps

Each Portfolio may enter into swaps to hedge its exposure to interest rates or credit risk. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals based upon or calculated by reference to changes in specified prices or rates for a specified amount of an underlying asset. The payment flows are usually netted against each other, with the difference being paid by one party to the other. In addition, collateral may be pledged or received by the Portfolios in accordance with the terms of the respective swaps to provide value and recourse to the Portfolios or their counterparties in the event of default, bankruptcy or insolvency by one of the parties to the swap.

abfunds.com AB MUNICIPAL INCOME FUND    ^|    169

NOTES TO FINANCIAL STATEMENTS (continued)

Risks may arise as a result of the failure of the counterparty to the swap to comply with the terms of the swap. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by the Portfolio, and/or the termination value at the end of the contract. Therefore, the Portfolio considers the creditworthiness of each counterparty to a swap in evaluating potential counterparty risk. This risk is mitigated by having a netting arrangement between the Portfolio and the counterparty and by the posting of collateral by the counterparty to the Portfolio to cover the Portfolios’ exposure to the counterparty. Additionally, risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Portfolio accrues for the interim payments on swaps on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swaps on the statement of assets and liabilities, where applicable. Once the interim payments are settled in cash, the net amount is recorded as realized gain/(loss) on swaps on the statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swaps. Upfront premiums paid or received for OTC swaps are recognized as cost or proceeds on the statement of assets and liabilities and are amortized on a straight line basis over the life of the contract. Amortized upfront premiums are included in net realized gain/(loss) from swaps on the statement of operations. Fluctuations in the value of swaps are recorded as a component of net change in unrealized appreciation/depreciation of swaps on the statement of operations.

Certain standardized swaps, including certain interest rate swaps and credit default swaps, are (or soon will be) subject to mandatory central clearing. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses, with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Centralized clearing will be required for additional categories of swaps on a phased-in basis based on requirements published by the Securities and Exchange Commission and Commodity Futures Trading Commission.

At the time the Portfolios enter into a centrally cleared swap, each Portfolio deposits and maintains as collateral an initial margin with the broker, as required by the clearinghouse on which the transaction is effected. Such amount is shown as cash collateral due from broker on the statement of assets and liabilities. Pursuant to the contract, the Portfolios agree to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Portfolios as unrealized gains or losses. Risks may arise from the potential inability of a counterparty to meet the terms of the

170    ^|    AB MUNICIPAL INCOME FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

contract. The credit/counterparty risk for centrally cleared swaps is generally less than non-centrally cleared swaps, since the clearinghouse, which is the issuer or counterparty to each centrally cleared swap, has robust risk mitigation standards, including the requirement to provide initial and variation margin. When the contract is closed, the Portfolios record a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the time it was closed.

Interest Rate Swaps:

Each Portfolio is subject to interest rate risk exposure in the normal course of pursuing its investment objectives. Because the Portfolios hold fixed rate bonds, the value of these bonds may decrease if interest rates rise. To help hedge against this risk and to maintain its ability to generate income at prevailing market rates, the Portfolios may enter into interest rate swaps. Interest rate swaps are agreements between two parties to exchange cash flows based on a notional amount. The Portfolios may elect to pay a fixed rate and receive a floating rate, or, receive a fixed rate and pay a floating rate on a notional amount.

In addition, the Portfolios may also enter into interest rate swap transactions to preserve a return or spread on a particular investment or portion of its portfolio, or protecting against an increase in the price of securities the Portfolios anticipate purchasing at a later date. Interest rate swaps involve the exchange by a Portfolio with another party of their respective commitments to pay or receive interest (e.g., an exchange of floating rate payments for fixed rate payments) computed based on a contractually-based principal (or “notional”) amount. Interest rate swaps are entered into on a net basis (i.e., the two payment streams are netted out, with the Portfolios receiving or paying, as the case may be, only the net amount of the two payments).

During the year ended May 31, 2021, the Portfolios held interest rate swaps for hedging purposes.

Inflation (CPI) Swaps:

Inflation swap agreements are contracts in which one party agrees to pay the cumulative percentage increase in a price index (the Consumer Price Index with respect to CPI swaps) over the term of the swap (with some lag on the inflation index), and the other pays a compounded fixed rate. Inflation swaps may be used to protect the net asset value, or NAV, of a Portfolio against an unexpected change in the rate of inflation measured by an inflation index since the value of these agreements is expected to increase if there are unexpected inflation increases.

abfunds.com AB MUNICIPAL INCOME FUND    ^|    171

NOTES TO FINANCIAL STATEMENTS (continued)

During the year ended May 31, 2021, the Portfolios held inflation (CPI) swaps for hedging purposes.

Credit Default Swaps:

Each Portfolio may enter into credit default swaps, including to manage its exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults by corporate and sovereign issuers held by the Portfolio, or to create exposure to corporate or sovereign issuers to which it is not otherwise exposed. The Portfolio may purchase credit protection (“Buy Contract”) or provide credit protection (“Sale Contract”) on the referenced obligation of the credit default swap. During the term of the swap, the Portfolio receives/(pays) fixed payments from/(to) the respective counterparty, calculated at the agreed upon rate applied to the notional amount. If the Portfolio is a buyer/(seller) of protection and a credit event occurs, as defined under the terms of the swap, the Portfolio will either (i) receive from the seller/(pay to the buyer) of protection an amount equal to the notional amount of the swap (the “Maximum Payout Amount”) and deliver/(take delivery of) the referenced obligation or (ii) receive/(pay) a net settlement amount in the form of cash or securities equal to the notional amount of the swap less the recovery value of the referenced obligation. In certain circumstances Maximum Payout Amounts may be partially offset by recovery values of the respective referenced obligations, upfront premium received upon entering into the agreement, or net amounts received from settlement of buy protection credit default swaps entered into by the Portfolio for the same referenced obligations with the same counterparty.

Credit default swaps may involve greater risks than if a Portfolio had invested in the referenced obligation directly. Credit default swaps are subject to general market risk, liquidity risk, counterparty risk and credit risk. If the Portfolio is a buyer of protection and no credit event occurs, it will lose the payments it made to its counterparty. If the Portfolio is a seller of protection and a credit event occurs, the value of the referenced obligation received by the Portfolio coupled with the periodic payments previously received, may be less than the Maximum Payout Amount it pays to the buyer, resulting in a net loss to the Portfolio.

Implied credit spreads over U.S. Treasuries of comparable maturity utilized in determining the market value of credit default swaps on issuers as of period end are disclosed in the portfolio of investments. The implied spreads serve as an indicator of the current status of the payment/performance risk and typically reflect the likelihood of default by the issuer of the referenced obligation. The implied credit spread of a particular reference obligation also reflects the cost of buying/selling

172    ^|    AB MUNICIPAL INCOME FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

protection and may reflect upfront payments required to be made to enter into the agreement. Widening credit spreads typically represent a deterioration of the referenced obligation’s credit soundness and greater likelihood of default or other credit event occurring as defined under the terms of the agreement. A credit spread identified as “Defaulted” indicates a credit event has occurred for the referenced obligation.

During the year ended May 31, 2021, the AB High Income Municipal Portfolio held credit default swaps for non-hedging purposes.

The Portfolios typically enter into International Swaps and Derivatives Association, Inc. Master Agreements (“ISDA Master Agreement”) with its OTC derivative contract counterparties in order to, among other things, reduce its credit risk to OTC counterparties. ISDA Master Agreements include provisions for general obligations, representations, collateral and events of default or termination. Under an ISDA Master Agreement, the Portfolios typically may offset with the OTC counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment (close-out netting) in the event of default or termination. In the event of a default by an OTC counterparty, the return of collateral with market value in excess of the Portfolios’ net liability, held by the defaulting party, may be delayed or denied.

The Portfolios’ ISDA Master Agreements may contain provisions for early termination of OTC derivative transactions in the event the net assets of the Portfolios decline below specific levels (“net asset contingent features”). If these levels are triggered, the Portfolios’ OTC counterparty has the right to terminate such transaction and require the Portfolios to pay or receive a settlement amount in connection with the terminated transaction. If OTC derivatives were held at period end, please refer to netting arrangements by the OTC counterparty tables below for additional details.

NOTE F

Risks Involved in Investing in the Portfolios

Market Risk—The value of the Portfolio’s assets will fluctuate as the bond market fluctuates. The value of the Portfolio’s investments may decline, sometimes rapidly and unpredictably, simply because of economic

abfunds.com AB MUNICIPAL INCOME FUND    ^|    183

NOTES TO FINANCIAL STATEMENTS (continued)

changes or other events, including public health crises (including the occurrence of a contagious disease or illness), that affect large portions of the market.

Credit Risk—An issuer or guarantor of a fixed-income security, or the counterparty to a derivatives or other contract, may be unable or unwilling to make timely payments of interest or principal, or to otherwise honor its obligations. The issuer or guarantor may default, causing a loss of the full principal amount of a security and accrued interest. The degree of risk for a particular security may be reflected in its credit rating. There is the possibility that the credit rating of a fixed-income security may be downgraded after purchase, which may adversely affect the value of the security. Investments in fixed-income securities with lower ratings tend to have a higher probability that an issuer will default or fail to meet its payment obligations.

Below Investment Grade Securities Risk—Investments in fixed-income securities with lower ratings (commonly known as “junk bonds”) have a higher probability that an issuer will default or fail to meet its payment obligations. These securities may be subject to greater price volatility due to such factors as specific corporate developments, interest rate sensitivity and negative performance of the junk bond market generally and may be more difficult to trade than other types of securities.

Municipal Market Risk—This is the risk that special factors may adversely affect the value of the municipal securities and have a significant effect on the yield or value of the Portfolios’ investments in municipal securities. These factors include economic conditions, political or legislative changes, public health crises, uncertainties related to the tax status of municipal securities, or the rights of investors in these securities. To the extent that the Portfolios invest more of their assets in a particular state’s municipal securities, the Portfolios may be vulnerable to events adversely affecting that state, including economic, political and regulatory occurrences, court decisions, terrorism, public health crises (including the occurrence of a contagious disease or illness) and catastrophic natural disasters, such as hurricanes, fires or earthquakes. For example, the novel coronavirus (COVID-19) pandemic has significantly stressed the financial resources of many issuers of municipal securities, which could impair any such issuer’s ability to meet its financial obligations when due and adversely impact the value of its securities held by the Portfolios. As the full effects of the COVID-19 pandemic on state and local economies and on issuers of municipal securities are still uncertain, the financial difficulties of issuers of municipal securities may continue or worsen, adversely affecting the performance of the Portfolios. The Portfolios’ investment in certain municipal securities with principal and interest payments that are made

184    ^|    AB MUNICIPAL INCOME FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

from the revenues of a specific project or facility, and not general tax revenues, may have increased risks. Factors affecting the project or facility, such as local business or economic conditions, could have a significant effect on the project’s ability to make payments of principal and interest on these securities.

Congress has previously considered making changes to the municipal securities provisions of the Internal Revenue Code that could change the U.S. federal income tax treatment of certain types of municipal securities.

The Portfolios invest from time to time in the municipal securities of Puerto Rico and other U.S. territories and their governmental agencies and municipalities, which are exempt from federal, state, and, where applicable, local income taxes. These municipal securities may have more risks than those of other U.S. issuers of municipal securities. Like many U.S. states and municipalities, Puerto Rico experienced a significant downturn during the 2007-2009 recession. Puerto Rico’s downturn was particularly severe, and Puerto Rico continues to face a very challenging economic and fiscal environment, including as a result of the COVID-19 pandemic. If the general economic situation in Puerto Rico continues to persist or worsens, the volatility and credit quality of Puerto Rican municipal securities could continue to be adversely affected, and the market for such securities may experience continued volatility.

Tax Risk—There is no guarantee that the income on the Portfolios’ municipal securities will be exempt from regular federal, and if applicable, state income taxes. From time to time, the U.S. Government and the U.S. Congress consider changes in federal tax law that could limit or eliminate the federal tax exemption for municipal bond income, which would in effect reduce the income received by shareholders from the Portfolios by increasing taxes on that income. In such event, the Portfolios’ net asset value, or NAV, could also decline as yields on municipal bonds, which are typically lower than those on taxable bonds, would be expected to increase to approximately the yield of comparable taxable bonds. Actions or anticipated actions affecting the tax exempt status of municipal bonds could also result in significant shareholder redemptions of portfolio shares as investors anticipate adverse effects on the Portfolios or seek higher yields to offset the potential loss of the tax deduction. As a result, the Portfolios would be required to maintain higher levels of cash to meet the redemptions, which would negatively affect the Portfolios’ yield.

Interest Rate Risk—Changes in interest rates will affect the value of investments in fixed-income securities. When interest rates rise, the value of existing investments in fixed-income securities tends to fall and this decrease in value may not be offset by higher income from new

abfunds.com AB MUNICIPAL INCOME FUND    ^|    185

NOTES TO FINANCIAL STATEMENTS (continued)

investments. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations. The current historically low interest rate environment heightens the risks associated with rising interest rates.

Duration Risk—Duration is a measure that relates the expected price volatility of a fixed-income security to changes in interest rates. The duration of a fixed-income security may be shorter than or equal to the full maturity of a fixed-income security. Fixed-income securities with longer durations have more risk and will decrease in price as interest rates rise.

Inflation Risk—This is the risk that the value of assets or income from investments will be less in the future as inflation decreases the value of money. As inflation increases, the value of the Portfolios’ assets can decline as can the value of the Portfolios’ distributions. This risk is significantly greater for fixed-income securities with longer maturities.

Financing and Related Transactions; Leverage and Other Risks—The Portfolios may utilize financial leverage, including tender option bond transactions, to seek to enhance the yield and net asset value. These objectives may not be achieved in all interest rate environments. Leverage creates certain risks for shareholders, including the likelihood of greater volatility of the net asset value. If income from the securities purchased from the funds made available by leverage is not sufficient to cover the cost of leverage, the Portfolios’ return will be less than if leverage had not been used. As a result, the amounts available for distribution as dividends and other distributions will be reduced. During periods of rising short-term interest rates, the interest paid on the floaters in tender option bond transactions would increase, which may adversely affect the Portfolios’ income and distribution to shareholders. A decline in distributions would adversely affect the Portfolios’ yield. If rising short-term rates coincide with a period of rising long-term rates, the value of the long-term municipal bonds purchased with the proceeds of leverage would decline, adversely affecting the net asset value.

In a tender option bond transaction, the Portfolios may transfer a highly rated fixed-rate municipal security to a broker, which, in turn, deposits the bond into a special purpose vehicle (typically, a trust) usually sponsored by the broker. The Portfolios receive cash and a residual interest security (sometimes referred to as an “inverse floater”) issued by the trust in return. The trust simultaneously issues securities, which pay an interest rate that is reset each week based on an index of high-grade short-term seven-day demand notes. These securities, sometimes referred to as “floaters”, are bought by third parties, including tax-exempt money market funds, and can be tendered by these holders to a liquidity provider at par, unless

186    ^|    AB MUNICIPAL INCOME FUND abfunds.com

NOTES TO FINANCIAL STATEMENTS (continued)

certain events occur. The Portfolios continue to earn all the interest from the transferred bond less the amount of interest paid on the floaters and the expenses of the trust, which include payments to the trustee and the liquidity provider and organizational costs. The Portfolios also use the cash received from the transaction for investment purposes or to retire other forms of leverage. Under certain circumstances, the trust may be terminated and collapsed, either by the Portfolios or upon the occurrence of certain events, such as a downgrade in the credit quality of the underlying bond, or in the event holders of the floaters tender their securities to the liquidity provider. See Note I to the Financial Statements “Floating Rate Notes Issued in Connection with Securities Held” for more information about tender option bond transactions.

The Portfolios may also purchase inverse floaters from a tender option bond trust in a secondary market transaction without first owning the underlying bond. The income received from an inverse floater varies inversely with the short-term interest rate paid on the floaters issued by the trust. The prices of inverse floaters are subject to greater volatility than the prices of fixed-income securities that are not inverse floaters. Investments in inverse floaters may amplify the risks of leverage. If short-term interest rates rise, the interest payable on the floaters would increase and income from the inverse floaters decrease.

Illiquid Investments Risk—Illiquid investments risk exists when certain investments are or become difficult to purchase or sell. Difficulty in selling such investments may result in sales at disadvantageous prices affecting the value of your investment in the Portfolios. Causes of illiquid investments risk may include low trading volumes, large positions and heavy redemptions of Portfolio shares. Illiquid investments risk may be higher in a rising interest rate environment, when the value and liquidity of fixed-income securities generally decline. Municipal securities may have more illiquid investments risk than other fixed-income securities because they trade less frequently and the market for municipal securities is generally smaller than many other markets.

Derivatives Risk—The Portfolios may enter into derivative transactions such as forwards, options, futures and swaps. Derivatives may be illiquid, difficult to price, and leveraged so that small changes may produce disproportionate losses for the Portfolios, and subject to counterparty risk to a greater degree than more traditional investments. Derivatives may result in significant losses, including losses that are far greater than the value of the derivatives reflected on the statement of assets and liabilities.

LIBOR Transition and Associated Risk—The Portfolios may invest in debt securities, derivatives or other financial instruments that utilize the

abfunds.com AB MUNICIPAL INCOME FUND    ^|    187

NOTES TO FINANCIAL STATEMENTS (continued)

London Interbank Offered Rate, or “LIBOR,” as a “benchmark” or “reference rate” for various interest rate calculations. The United Kingdom Financial Conduct Authority, which regulates LIBOR, will cease publishing certain LIBOR benchmarks at the end of 2021. Although certain LIBOR rates are intended to be published until June 2023, banks are strongly encouraged to cease entering into agreements with counterparties referencing LIBOR by the end of 2021. Although financial regulators and industry working groups have suggested alternative reference rates, such as the European Interbank Offer Rate, the Sterling Overnight Interbank Average Rate and the Secured Overnight Financing Rate, global consensus on alternative rates is lacking and the process for amending existing contracts or instruments to transition away from LIBOR is underway but remains incomplete. The elimination of LIBOR or changes to other reference rates or any other changes or reforms to the determination or supervision of reference rates could have an adverse impact on the market for, or value of, any securities or payments linked to those reference rates, which may adversely affect the Portfolios’ performance and/or net asset value. Uncertainty and risk also remain regarding the willingness and ability of issuers and lenders to include revised provisions in new and existing contracts or instruments. Consequently, the transition away from LIBOR to other reference rates may lead to increased volatility and illiquidity in markets that are tied to LIBOR, fluctuations in values of LIBOR-related investments or investments in issuers that utilize LIBOR, increased difficulty in borrowing or refinancing and diminished effectiveness of hedging strategies, potentially adversely affecting the Portfolios’ performance. Furthermore, the risks associated with the expected discontinuation of LIBOR and transition may be exacerbated if the work necessary to effect an orderly transition to an alternative reference rate is not completed in a timely manner. Because the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects could occur prior to the end of 2021.

Indemnification Risk—In the ordinary course of business, the Portfolios enter into contracts that contain a variety of indemnifications. The Portfolios’ maximum exposure under these arrangements is unknown. However, the Portfolios have not had prior claims or losses pursuant to these indemnification provisions and expect the risk of loss thereunder to be remote. Therefore, the Portfolios have not accrued any liability in connection with these indemnification provisions.

Management Risk—The Portfolios are subject to management risk because they are an actively-managed investment funds. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon,

quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.

NOTE G

Joint Credit Facility

A number of open-end mutual funds managed by the Adviser, including the Portfolios, participate in a $325 million revolving credit facility (the “Facility”) intended to provide short-term financing, if necessary, subject to certain restrictions in connection with abnormal redemption activity. Commitment fees related to the Facility are paid by the participating funds and are included in miscellaneous expenses in the statement of operations. The Portfolios did not utilize the Facility during the year ended May 31, 2021.

NOTE I

Floating Rate Notes Issued in Connection with Securities Held

Each Portfolio may engage in tender option bond transactions in which the Portfolio may transfer a fixed rate bond (“Fixed Rate Bond”) into a Special Purpose Vehicle (the “SPV”, which is generally organized as a trust). The Portfolio buys a residual interest in the assets and cash flows of the SPV, often referred to as an inverse floating rate obligation (“Inverse Floater”). The SPV also issues floating rate notes (“Floating Rate Notes”) which are sold to third parties. The Floating Rate Notes pay interest at rates that generally reset weekly and their holders have the option to tender their notes to a liquidity provider for redemption at par. The Inverse Floater held by the Portfolio gives the Portfolio the right (1) to cause the holders of the Floating Rate Notes to tender their notes at par, and (2) to have the trustee transfer the Fixed Rate Bond held by the SPV to the Portfolio, thereby collapsing the SPV. The SPV may also be collapsed in certain other circumstances. In accordance with U.S. GAAP requirements regarding accounting for transfers and servicing of financial assets and extinguishments of liabilities, the Portfolio accounts for the transaction described above as a secured borrowing by including the Fixed Rate Bond in its portfolio of investments and the Floating Rate Notes as a liability under the caption “Payable for floating rate notes issued” in its statement of assets and liabilities. Interest expense related to the Portfolios’ liability with respect to Floating Rate Notes is recorded as incurred. The interest expense is also included in the Portfolios’ expense ratio. At May 31, 2021, the amount of Floating Rate Notes outstanding was $220,760,000 and the related interest rate ranged from 0.08% to 0.27% for AB High Income Municipal Portfolio. At May 31, 2021, AB California Portfolio, AB National Portfolio and AB New York Portfolio did not have any Floating Rate Notes outstanding. For the year ended May 31, 2021, the average amount of

NOTES TO FINANCIAL STATEMENTS (continued)

Floating Rate Notes outstanding and the daily weighted average interest rate were as follows:

Portfolio	Average Amount Outstanding		Weighted Average Interest Rate
AB High Income Municipal	$	199,343,795		0.92	%

Each Portfolio may also purchase Inverse Floaters in the secondary market without first owning the underlying bond. Such an Inverse Floater is included in the portfolio of investments but is not required to be treated as a secured borrowing and reflected in the Portfolios’ financial statements as a secured borrowing. For the year ended May 31, 2021, AB California Portfolio engaged in such transactions.

The final rules implementing section 619 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Volcker Rule”) were issued on December 10, 2013. The Volcker Rule precludes banking entities and their affiliates from (i) sponsoring residual interest bond programs, such as the Fund’s TOB transactions (as such programs were then previously or are presently structured), and (ii) continuing certain relationships with or certain services for residual interest bond programs.

Recent Accounting Pronouncements

In March 2020, the Financial Accounting Standards Board issued an Accounting Standards Update, ASU 2020-04, “Reference Rate Reform (Topic 848) — Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” ASU 2020-04 provides optional guidance to ease the potential accounting burden due to the discontinuation of the LIBOR and other interbank-offered based reference rates. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. Management is currently evaluating the impact, if any, of applying ASU 2020-04.

NOTE K

Subsequent Events

Management has evaluated subsequent events for possible recognition or disclosure in the financial statements through the date the financial statements are issued. Management has determined that there are no material events that would require disclosure in the Portfolios’ financial statements through this date.

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of

AB Municipal Income Fund, Inc.:

Opinion on the Financial Statements

We have audited the accompanying statements of assets and liabilities of AB Municipal Income Fund, Inc. (the “Fund”) (comprising the AB California Portfolio, AB High Income Municipal Portfolio, AB National Portfolio and AB New York Portfolio (collectively referred to as the “Portfolios”)), including the portfolios of investments, as of May 31, 2021, and the related statements of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, the financial highlights for each of the five years in the period then ended and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of each of the Portfolios comprising AB Municipal Income Fund, Inc. at May 31, 2021, the results of their operations for the year then ended, the changes in net assets for each of the two years in the period then ended and their financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on each of the Portfolios’ financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of the Fund’s internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud,

208    ^|    AB MUNICIPAL INCOME FUND abfunds.com

REPORT OF INDEPENDENT REGISTERED

and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of May 31, 2021, by correspondence with the custodian and others or by other appropriate auditing procedures where replies from others were not received. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the auditor of one or more of the AB investment companies since 1968.

Operation and Effectiveness of the Portfolios’ Liquidity Risk Management Program:

In October 2016, the Securities and Exchange Commission (“SEC”) adopted the open-end fund liquidity rule (the “Liquidity Rule”). In June 2018 the SEC adopted a requirement that funds disclose information about the operation and effectiveness of their Liquidity Risk Management Program (“LRMP”) in their reports to shareholders.

One of the requirements of the Liquidity Rule is for the Portfolios to designate an Administrator of the Portfolios’ Liquidity Risk Management Program. The Administrator of the Portfolios’ LRMP is AllianceBernstein L.P., the Portfolios’ investment adviser (the “Adviser”). The Adviser has delegated the responsibility to its Liquidity Risk Management Committee (the “Committee”).

Another requirement of the Liquidity Rule is for the Fund’s Board of Trustees (the “Fund Board”) to receive an annual written report from the Administrator of the LRMP, which addresses the operation of the Portfolios’ LRMP and assesses its adequacy and effectiveness. The Adviser provided the Fund Board with such annual report during the first quarter of 2021, which covered the period January 1, 2020 through December 31, 2020 (the “Program Reporting Period”).

The LRMP’s principal objectives include supporting the Portfolios’ compliance with limits on investments in illiquid assets and mitigating the risk that the Portfolios will be unable to meet their redemption obligations in a timely manner.

Pursuant to the LRMP, the Portfolios classify the liquidity of their portfolio investments into one of the four categories defined by the SEC: Highly Liquid, Moderately Liquid, Less Liquid, and Illiquid. These classifications are reported to the SEC on Form N-PORT.

During the Program Reporting Period, the Committee reviewed whether the Portfolios’ strategy is appropriate for an open-end structure, incorporating any holdings of less liquid and illiquid assets. If the Portfolios participated in derivative transactions, the exposure from such transactions were considered in the LRMP.

The Committee also performed an analysis to determine whether the Portfolios are required to maintain a Highly Liquid Investment Minimum (“HLIM”). The Committee also incorporated the following information when determining the Portfolios’ reasonably anticipated trading size for purposes of liquidity monitoring: historical net redemption activity, the Portfolios’ concentration in an issuer, shareholder concentration, investment performance, total net assets, and distribution channels.

220    ^|    AB MUNICIPAL INCOME FUND abfunds.com

The Adviser informed the Fund Board that the Committee believes the Portfolios’ LRMP is adequately designed, has been implemented as intended, and has operated effectively since its inception. No material exceptions have been noted since the implementation of the LRMP. During the Program Reporting Period, beginning in March 2020, all financial markets experienced extreme levels of price volatility and relative illiquidity resulting from the COVID-19 impacts on the global economy. This extreme relative illiquidity resulted in significantly wider bid-ask spreads to transact in securities, including many of those securities held by the Portfolios, and in a diminished depth of liquidity in most markets, to varying degrees. Nonetheless, there were no liquidity events that impacted the Portfolios or their ability to timely meet redemptions during the Program Reporting Period.

Information Regarding the Review and Approval of the Advisory Agreement in Respect of Each Fund

The disinterested directors (the “directors”) of AB Municipal Income Fund, Inc. (the “Company”) unanimously approved the continuance of the Company’s Advisory Agreement with the Adviser in respect of each of the portfolios listed below (each, a “Fund” and collectively, the “Funds”) at a meeting held by video conference on November 3-5, 2020 (the “Meeting”):

• AB California Portfolio

• AB High Income Municipal Portfolio

• AB National Portfolio

• AB New York Portfolio

Prior to approval of the continuance of the Advisory Agreement in respect of each Fund, the directors had requested from the Adviser, and received and evaluated, extensive materials. They reviewed the proposed continuance of the Advisory Agreement with the Adviser and with experienced counsel who are independent of the Adviser, who advised on the relevant legal standards. The directors also reviewed additional materials, including comparative analytical data prepared by the Senior Analyst for each Fund. The directors also discussed the proposed continuances in private sessions with counsel.

The directors considered their knowledge of the nature and quality of the services provided by the Adviser to the Funds gained from their experience as directors or trustees of most of the registered investment companies advised by the Adviser, their overall confidence in the Adviser’s integrity and competence they have gained from that experience, the Adviser’s initiative in identifying and raising potential issues with the directors and its responsiveness, frankness and attention to concerns raised by the directors in the past, including the Adviser’s willingness to consider and implement organizational and operational changes designed to improve investment results and the services provided to the AB Funds. The directors noted that they have four regular meetings each year, at each of which they review extensive materials and information from the Adviser, including information on the investment performance of the Funds and the money market fund advised by the Adviser in which the Funds invest a portion of their assets.

The directors also considered all factors they believed relevant, including the specific matters discussed below. During the course of their deliberations, the directors evaluated, among other things, the reasonableness of the advisory fee in respect of each Fund. The directors did not identify any particular information that was all-important or controlling, and different directors may have attributed different weights to the various factors. The directors determined that the selection of the Adviser to manage each Fund and the overall arrangements between each Fund and the Adviser,

222    ^|    AB MUNICIPAL INCOME FUND abfunds.com

as provided in the Advisory Agreement, including the advisory fee, were fair and reasonable in light of the services performed, expenses incurred and such other matters as the directors considered relevant in the exercise of their business judgment. The material factors and conclusions that formed the basis for the directors’ determinations included the following:

Nature, Extent and Quality of Services Provided

The directors considered the scope and quality of services provided by the Adviser under the Advisory Agreement, including the quality of the investment research capabilities of the Adviser and the other resources it has dedicated to performing services for each Fund. The directors noted that the Adviser from time to time reviews each Fund’s investment strategies and from time to time proposes changes intended to improve a Fund’s relative or absolute performance for the directors’ consideration. They also noted the professional experience and qualifications of each Fund’s portfolio management team and other senior personnel of the Adviser. The directors also considered that the Advisory Agreement provides that each Fund will reimburse the Adviser for the cost to it of providing certain clerical, accounting, administrative and other services to such Fund by employees of the Adviser or its affiliates. Requests for these reimbursements are made on a quarterly basis and subject to approval by the directors. Reimbursements, to the extent requested and paid in respect of a Fund, result in a higher rate of total compensation from such Fund to the Adviser than the fee rate stated in the Advisory Agreement. The directors noted that the methodology used to determine the reimbursement amounts had been reviewed by an independent consultant at the request of the directors. The quality of administrative and other services, including the Adviser’s role in coordinating the activities of each Fund’s other service providers, also was considered. The directors concluded that, overall, they were satisfied with the nature, extent and quality of services provided to each of the Funds under the Advisory Agreement.

Costs of Services Provided and Profitability

The directors reviewed a schedule of the revenues and expenses and related notes indicating the profitability of each Fund to the Adviser for calendar years 2018 and 2019 that had been prepared with an expense allocation methodology arrived at in consultation with an independent consultant at the request of the directors. The directors noted the assumptions and methods of allocation used by the Adviser in preparing fund-specific profitability data and understood that there are a number of potentially acceptable allocation methodologies for information of this type. The directors noted that the profitability information reflected all revenues and expenses of the Adviser’s relationships with the Funds, including those relating to its subsidiaries that provide transfer agency and distribution services to the Funds. The directors recognized that it is difficult to make comparisons of the profitability of the Advisory Agreement with the profitability of fund advisory contracts for unaffiliated funds because

abfunds.com AB MUNICIPAL INCOME FUND    ^|    223

comparative information is not generally publicly available and is affected by numerous factors. The directors focused on the profitability of the Adviser’s relationships with the Funds before taxes and distribution expenses. The directors concluded that the Adviser’s level of profitability from its relationship with each Fund was not unreasonable.

Fall-Out Benefits

The directors considered the other benefits to the Adviser and its affiliates from their relationships with the Funds and the money market fund advised by the Adviser in which the Funds invest, including, but not limited to, benefits relating to 12b-1 fees and sales charges received by the Funds’ principal underwriter (which is a wholly owned subsidiary of the Adviser) in respect of certain classes of the Funds’ shares; and transfer agency fees paid by the Funds to a wholly owned subsidiary of the Adviser. The directors recognized that the Adviser’s profitability would be somewhat lower without these benefits. The directors understood that the Adviser also might derive reputational and other benefits from its association with the Funds.

Investment Results

In addition to the information reviewed by the directors in connection with the Meeting, the directors receive detailed performance information for each Fund at each regular Board meeting during the year.

At the Meeting, the directors reviewed performance information prepared by an independent service provider (the “15(c) service provider”), showing the performance of the Class A Shares of each Fund against a group of similar funds (“peer group”) and a larger group of similar funds (“peer universe”), each selected by the 15(c) service provider, and information prepared by the Adviser showing performance of the Class A Shares against a broad-based securities market index, in each case for the 1-, 3-, 5- and 10-year period ended July 31, 2020 and (in the case of comparisons with the broad-based securities market index) for the period from inception. Based on their review, the directors concluded that each Fund’s investment performance was acceptable.

Advisory Fees and Other Expenses

The directors considered the advisory fee rate payable by each Fund to the Adviser and information prepared by the 15(c) service provider concerning advisory fee rates payable by other funds in the same category as such Fund. The directors recognized that it is difficult to make comparisons of advisory fees because there are variations in the services that are included in the fees payable by other funds. The directors compared each Fund’s contractual effective advisory fee rate with a peer group median and noted that it was above the median in the case of each of AB California Portfolio and AB High Income Municipal Portfolio. The directors took into account the impact on the advisory fee rate of the administrative expense reimbursement paid to the Adviser in the latest fiscal year.

224    ^|    AB MUNICIPAL INCOME FUND abfunds.com

The Adviser informed the directors that there were no institutional products managed by the Adviser that utilize investment strategies similar to those of any of the Funds. In the case of each of AB California Portfolio, AB National Portfolio and AB New York Portfolio, the directors compared each Fund’s advisory fee rate with that for another fund advised by the Adviser utilizing similar investment strategies.

In connection with their review of each Fund’s advisory fee, the directors also considered the total expense ratio of the Class A shares of each Fund in comparison to a peer group and a peer universe selected by the 15(c) service provider. The expense ratio of each Fund was based on the Fund’s latest fiscal year, and the directors considered the Adviser’s expense cap for each Fund. The directors noted that it was likely that the expense ratios of some of the other funds in each Fund’s category were lowered by waivers or reimbursements by those funds’ investment advisers, which in some cases might be voluntary or temporary. The directors view expense ratio information as relevant to their evaluation of the Adviser’s services because the Adviser is responsible for coordinating services provided to the Funds by others. Based on their review, the directors concluded the expense ratio for each of AB High Income Municipal Portfolio, AB National Portfolio and AB New York Portfolio was acceptable. The directors noted that the expense ratio for AB California Portfolio was above the medians. After reviewing and discussing the Adviser’s explanations of the reasons for this, the directors concluded that the Fund’s expense ratio was acceptable.

Economies of Scale

The directors noted that the advisory fee schedule for the Funds contains breakpoints that reduce the fee rates on assets above specified levels, and that the net assets of AB High Income Municipal Portfolio were above the first breakpoint level. Accordingly, the Fund’s current effective advisory fee rate reflected a reduction due to the breakpoint and would be further reduced to the extent the net assets of the Fund increase. The directors took into consideration prior presentations by an independent consultant on economies of scale in the mutual fund industry and for the AB Funds, and presentations from time to time by the Adviser concerning certain of its views on economies of scale. The directors also previously discussed economies of scale with an independent fee consultant. The directors also had requested and received from the Adviser certain updates on economies of scale in advance of the Meeting. The directors believe that economies of scale may be realized (if at all) by the Adviser across a variety of products and services, and not only in respect of a single fund. The directors noted that there is no established methodology for setting breakpoints that give effect to the fund-specific services provided by a fund’s adviser and to the economies of scale that an adviser may realize in its overall mutual fund business or those components of it which directly or indirectly affect a fund’s operations. The directors observed that in the mutual fund industry as a whole, as well as among funds similar to the

abfunds.com AB MUNICIPAL INCOME FUND    ^|    225

Funds, there is no uniformity or pattern in the fees and asset levels at which breakpoints (if any) apply. The directors also noted that the advisory agreements for many funds do not have breakpoints at all. Having taken these factors into account, the directors concluded that, in the case of AB High Income Municipal Portfolio, the Fund’s breakpoint arrangements were acceptable and provide a means for sharing economies of scale, and, in the case of the other Funds, such Funds’ shareholders would benefit from a sharing of economies of scale in the event a Fund’s net assets exceed a breakpoint in the future.
