President’s Letter

Dear Shareholders,

The last few years have seen investors face some unprecedented challenges, from a global pandemic that shuttered much of the world’s economy for months, to geopolitical strife, to rising inflation that has reached levels not seen in decades.

While economies in most of the world have reopened as COVID-19 has begun slowly transitioning to an “endemic” disease, the pandemic’s effects are still with us. The easier monetary and fiscal policies enacted to provide stimulus as economies struggled through COVID-19-related restrictions and lockdowns, and ongoing supply chain issues, which were, at least in part, an outgrowth of the same virus-containment measures, were among the numerous factors that combined to begin driving inflation levels higher as the 2022 calendar year got underway.

With rising inflation already a concern, investor sentiment sharply deteriorated in the first quarter of this year, with the negativity driven largely by Russia’s invasion of Ukraine in February as well as signs that inflation was more entrenched than transitory in many regions of the world. The war and the resulting economic sanctions placed on Russia by the US and European governments also contributed to a spike in energy prices, given that Russia is a major exporter of natural gas as well as other resources, particularly to Europe.

The persistently high inflation readouts led key central banks, including the US Federal Reserve (Fed), to signal a tightening of monetary policy. The Fed had already announced that it would taper its bond purchases and eventually end its pandemic-era quantitative easing program by the spring of 2022; and, with US inflation hitting 40-year highs, the Fed began aggressively raising its benchmark federal funds rate target range, while indicating that more rate hikes were likely. The magnitude of the rate increases heightened investors’ concerns about the ability of the Fed and other central banks to cool inflation without triggering a recession.

Due to what has been, so far, a tumultuous 2022 calendar year for investors, the performance of most asset classes, especially riskier assets such as equities and corporate bonds, has turned negative, as market participants have tried to ascertain the direction and progression of Fed policy, economic growth, the war in Ukraine, and other factors. In fact, the third quarter of 2022 marked the first time since 1976 that both equities and bonds had posted three consecutive quarters of negative returns. The 2022 US mid-term election results are another important benchmark that investors are closely monitoring, as political uncertainty has often contributed to increased market volatility.

In times like these, we at Amundi US believe our approach to investing is more appropriate than ever. Since 1928, Amundi US’s investment process has been built on a foundation of fundamental research and active management, principles which have guided our investment decisions for more than 90 years. We believe active management – that is, making active investment decisions – can help mitigate the risks during periods of market volatility.

At Amundi US, active management begins with our own fundamental, bottom-up research process. Our team of dedicated research analysts and portfolio managers analyzes each security under consideration, communicating frequently with the management teams of the companies and other entities issuing the securities, and working together to identify those securities that we believe best meet our investment criteria for our family of funds. Our risk management approach begins with each security under consideration, as we strive to develop a deep understanding of the potential opportunity, while considering any potential risk factors.

Today, as shareholders, we have many options. It is our view that active management can serve shareholders well, not only when markets are thriving, but also during periods of market stress. As you consider your long-term investment goals, we encourage you to work with your financial professional to develop an investment plan that paves the way for you to pursue both your short-term and long-term goals.

We greatly appreciate the trust you have placed in us and look forward to continuing to serve you in the future.

Portfolio Management Discussion | 9/30/22

In the following interview, Jonathan Chirunga and David Eurkus discuss the factors that influenced the performance of Pioneer Municipal High Income Advantage Fund, Inc. during the six-month period ended September 30, 2022. Mr. Chirunga, Managing Director, Director of High-Yield Municipals, and a portfolio manager at Amundi Asset Management US, Inc. (Amundi US), is responsible for the day-to-day management of the Fund, along with Mr. Eurkus, Managing Director, Director of Municipals, and a portfolio manager at Amundi US.

QHow did the Fund perform during the six-month period ended September 30, 2022?
APioneer Municipal High Income Advantage Fund, Inc. returned -17.62% at net asset value (NAV) and -21.00% at market price during the six-month period ended September 30, 2022. During the same six-month period, the Fund’s benchmarks, the Bloomberg US Municipal High Yield Bond Index and the Bloomberg Municipal Bond Index, returned -10.16% and -6.30% at NAV, respectively. The Bloomberg US Municipal High Yield Bond Index is an unmanaged measure of the performance of lower-rated municipal bonds, while the Bloomberg Municipal Bond Index is an unmanaged measure of the performance of investment-grade municipal bonds. Unlike the Fund, the two indices do not use leverage. While the use of leverage increases investment opportunity, it also increases investment risk.

During the same six-month period, the average return at NAV of the 29 closed end funds in Morningstar’s Closed End High Yield Municipal category (which may or may not be leveraged) was -13.41%, and the average return at market price of the closed-end funds within the same Morningstar category was -16.46%.

The shares of the Fund were selling at a 12.3% discount to NAV on September 30, 2022. Comparatively, the shares of the Fund were selling at a 8.6% discount to NAV on March 31, 2022.

On September 30, 2022, the standardized 30-day SEC yield of the Fund’s shares was 4.71%.*

*The 30-day SEC yield is a standardized formula that is based on the hypothetical annualized earning power (investment income only) of the Fund’s portfolio securities during the period indicated.

QHow would you describe the investment environment in the municipal bond market during the six-month period ended September 30, 2022?

A Consistent with the poor returns for the broader fixed-income market, municipal issues suffered unusually weak performance over the six-month period. Two factors played a role in the market’s sizable downturn.

First, in March 2022, prior to the start of the six-month period, the US Federal Reserve System (Fed) had sought to combat high levels of inflation by ending its pandemic-era quantitative easing program and beginning to raise interest rates. The Fed had increased the target range of the federal funds rate by 25 basis points (bps), or one-quarter of one percentage point, at its March meeting, then followed up with an increase of 50 bps in May and three increases of 75 bps each in June, July, and September, respectively. As of September 30, 2022, investors were anticipating at least two more rate increases before year-end. The Fed’s actions contributed to an across-the-board rise in government bond yields over the six-month period. The 10-year US Treasury note, which came into the period with a yield of 2.32%, rose to 3.83% by the final day of September. (Bond prices and yields move in opposite directions.)

The second key factor affecting the market was that, along with the rise in prevailing yields, came an accompanying increase in yield spreads for municipal bonds relative to US Treasuries. (Yield, or credit spreads, are commonly defined as the differences in yield between Treasuries and other types of fixed-income securities with similar maturities.) The combination of Russia’s invasion of Ukraine, ongoing supply chain disruptions, and questions about the direction of the economy led to underperformance for the bond market’s “spread sectors” in relation to Treasuries. In combination, those developments led to substantial outflows from the municipal bond market during the period, which further weighed on bond prices. (Spread sectors are nongovernmental fixed-income market sectors that offer higher yields, at greater risk, than governmental investments.)

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 5


 

 

 

High-yield municipals lagged their investment-grade counterparts during the period, due in part to negative performance from credit-sensitive sectors, including housing bonds, pollution control revenue (PCR) bonds, industrial development revenue (IDR) bonds, hospital bonds, tobacco master settlement agreement (MSA) bonds, and bonds issued by the Commonwealth of Puerto Rico.

Although performance for the asset class was poor, fundamentals within the municipal bond market have remained firm. The gradual reopening of the economy, substantial federal aid through government-stimulus packages in 2020-2021, and rising tax receipts have all contributed to a steady improvement in the financial health of municipal issuers. The default rate within the municipal bond market also has remained very low, helping to illustrate the gap between price performance and underlying issuer strength.

QWhat factors affected the Fund’s performance relative to the Bloomberg municipal bond indices during the six-month period ended September 30, 2022?
AThe use of leverage was a key detractor from the Fund’s benchmark-relative performance during the period. Unlike the Fund, the two indices do not use leverage. While the use of leverage may increase the Fund’s income and total return potential, it also increases investment risk, particularly in a negative market environment such as the one we experienced over the past six months.

At the sector level, the Fund’s relative performance benefited from an underweight to special-tax revenue bonds. A large portion of the sector consists of real estate development deals, which underperformed during the period given that rising mortgage rates weighed on the outlook for the property sector. Security selection results within the hospital sector were another positive contributor to the Fund’s relative returns. Conversely, the Fund’s positioning in the PCR and IDR sectors – that is, tax-exempt debt issued by municipal entities to finance projects used by private corporations – detracted from benchmark-relative returns, as both sectors struggled during the six-month period.

6 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

From a ratings perspective, the Fund’s allocation to non-rated municipal bonds was a top positive contributor to benchmark-relative performance for the six-month period. Each non-rated municipal bond is subject to our in-depth credit analysis process before we consider adding it to the portfolio, and our team of analysts assigns every non-rated bond an internal rating. In addition, we review all obligors of the non-rated bonds held in the portfolio, and seek to make once-per-year site visits (optimally) to help ensure, in our view, that the ability of the non-rated issuers to maintain their coupon payments is not at risk.

The Fund’s underweight allocation to bonds issued by the Commonwealth of Puerto Rico also aided relative performance, as the Commonwealth’s debt lagged the broader municipal bond market. The decision to carry a portfolio underweight to Puerto Rico was a function of our continued selectivity with regard to investing in bonds that have gone through restructuring in federal courts, or that we believe could face restructuring in the future.

At the individual security level, the leading positive contributors to the Fund’s relative returns during the period were holdings of bonds issued by the Illinois Development Authority (special facilities revenue) and the Massachusetts State Development Finance Agency (revenue). On the negative side, portfolio positions in Capital Trust Agency Senior Living revenue bonds (Florida) and Metropolitan Pier & Exposition Authority (Illinois) revenue bonds were the largest individual detractors from the Fund’s relative performance during the period.

QDid the Fund’s distributions** to shareholders change during the six-month period ended August 31, 2022?
AYes, in a rising interest-rate environment, the Fund’s monthly distribution rate rose from $0.04000 cents per share/per month at the beginning of the period, to $0.04400 cents per share/per month as of September 30, 2022, with the increase occurring in August. Please note that the Fund has drawn on accumulated net investment income in paying the Fund's distributions in recent periods, and these reserves may be depleted over time.

** Distributions are not guaranteed.

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 7


 

 

 

QDid the level of leverage in the Fund change during the six-month period ended September 30, 2022?
AOn September 30, 2022, 43.7% of the Fund’s total managed assets were financed by leverage obtained through the issuance of Variable Rate MuniFund Term Preferred Shares, compared with 41.2% of the Fund’s total managed assets financed by leverage at the start of the period on April 1, 2022. During the six-month period, the Fund decreased the absolute amount of funds borrowed by a total of $20 million, to $160 million as of September 30, 2022. The change in the percentage of the Fund’s total managed assets financed by leverage during the six-month period was the result of a decrease in the value of the Fund’s total managed assets.
QDid the Fund have any exposure to derivative securities during the six-month period ended September 30, 2022?
ANo, the Fund’s portfolio had no exposure to derivative securities.
QWhat is your investment outlook?
AWe see the potential for further market volatility given the broad uncertainty surrounding inflation, Fed monetary policies, and developments on the geopolitical front. However, credit conditions have remained stable across the municipal bond space, and we foresee low odds of a wholesale rise in default risk. The ratio of ratings upgrades to downgrades within the municipal market has remained favorable as well. We also have seen record tax payments in issuing states, as well as budget surpluses. While corporate and government debt levels have risen significantly since the financial crisis of 2008, the municipal market has continued to hover at around $4 trillion in outstanding debt. We believe this provides a positive underpinning for the market and indicates improving financial discipline among municipal issuers. In our view, those factors indicate that the weakness in prices has not been accompanied by a meaningful decline in underlying fundamentals in the municipal market.

8 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

We would also note that the recent market downturn has caused the ratio of tax-exempt yields to US Treasury yields to rise (the Municipal-to-Treasury ratio), which has often been an indication of improving value in the market, given that the higher the Municipal-to-Treasury ratio, the more attractive municipals are relative to Treasuries. We believe the attractive yields offered by municipal bonds may help drive rising demand, which would be a positive, especially since expectations are for limited supply through year-end.

As is always the case, headline news events have had a minimal effect on our day-to-day approach to managing the portfolio. Our goal is to invest the Fund in what we believe are fundamentally sound credits with attractive yields, while maintaining an appropriate level of portfolio diversification***. We also seek to avoid experiencing defaults in the portfolio through our emphasis on fundamental research. That approach was successful over the past six months, as the Fund did not have any exposure to bonds that defaulted. We believe this steady, long-term approach remains the most effective way to identify opportunities and to help minimize the risk associated with investing in the high-yield municipal market.

Please refer to the Schedule of Investments on pages 16–25 for a full listing of Fund securities.

All investments are subject to risk, including the possible loss of principal. In the past several years, financial markets have experienced increased volatility and heightened uncertainty. The market prices of securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political, or regulatory conditions, recessions, inflation, changes in interest or currency rates, lack of liquidity in the bond markets, the spread of infectious illness or other public health issues, armed conflict including Russia's military invasion of Ukraine, sanctions against Russia, other nations or individuals or companies and possible countermeasures, or adverse investor sentiment. These conditions may continue, recur, worsen or spread.

*** Diversification does not assure a profit nor protect against loss.

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 9


 

 

 

The Fund’s investments, payment obligations and financing terms may be based on floating rates, such as LIBOR (London Interbank Offered Rate), or SOFR (Secured Overnight Financing Rate). Plans are underway to phase out the use of LIBOR. There remains uncertainty regarding the nature of any replacement rate and the impact of the transition from LIBOR on the Fund, issuers of instruments in which the Fund invests, and financial markets generally.

Investments in high-yield or lower-rated securities are subject to greater-than-average risk.

The Fund may invest in securities of issuers that are in default or that are in bankruptcy.

A portion of income may be subject to state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax.

When interest rates rise, the prices of fixed-income securities held by the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities held by the Fund will generally rise.

The value of municipal securities can be adversely affected by changes in financial condition of municipal issuers, lower revenues, and regulatory and political developments. By concentrating in municipal securities, the portfolio is more susceptible to adverse economic, political or regulatory developments than is a portfolio that invests more broadly.

Investments in the Fund are subject to possible loss due to the financial failure of the issuers of the underlying securities and the issuers’ inability to meet their debt obligations.

The Fund currently uses leverage through the issuance of preferred shares. Leverage creates significant risks, including the risk that the Fund's incremental income or capital appreciation for investments purchased with the proceeds of leverage will not be sufficient to cover the cost of leverage, which may adversely affect the return for the holders of common shares.

The Fund is required to meet certain regulatory and rating agency asset coverage requirements in connection with its outstanding preferred shares. In order to maintain required asset coverage levels, the Fund may be required to

10 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

alter the composition of its investment portfolio or take other actions, such as redeeming preferred shares with the proceeds from portfolio transactions, at what might be inopportune times in the market. Such actions could reduce the net earnings or returns to holders of the Fund's common shares over time, which is likely to result in a decrease in the market value of the Fund's shares.

These risks may increase share price volatility.

Call 1-800-710-0935 or visit www.amundi.com/us for the most recent month-end performance results. Current performance may be lower or higher than the performance data quoted.

Performance data shown represents past performance. Past performance is no guarantee of future results. Investment return and market price will fluctuate, and your shares may trade below NAV due to such factors as interest rate changes and the perceived credit quality of borrowers.

Total investment return does not reflect broker sales charges or commissions. All performance is for common shares of the Fund.

Shares of closed-end funds, unlike open-end funds, are not continuously offered. There is a one-time public offering and, once issued, shares of closed-end funds are bought and sold in the open market through a stock exchange, and frequently trade at prices lower than their NAV. NAV per common share is total assets less total liabilities, which include preferred shares, divided by the number of common shares outstanding.

When NAV is lower than market price, dividends are assumed to be reinvested at the greater of NAV or 95% of the market price. When NAV is higher, dividends are assumed to be reinvested at prices obtained through open-market purchases under the Fund’s dividend reinvestment plan.

The performance table and graph do not reflect the deduction of fees and taxes that a shareowner would pay on Fund distributions or the sale of Fund shares. Had these fees and taxes been reflected, performance would have been lower.

The Bloomberg Municipal Bond Index is an unmanaged, broad measure of the municipal bond market. The Bloomberg U.S. Municipal High Yield Bond Index is unmanaged, totals over $26 billion in market value and maintains over 1,300 securities. Municipal bonds in this index have the following requirements: maturities of one year or greater, sub investment grade (below Baa or non-rated), fixed coupon rate, issue date later than 12/31/90, deal size over $20 million, maturity size of at least $3 million. Index returns are calculated monthly, assume reinvestment of dividends and, unlike Fund returns, do not reflect any fees, expenses or sales charges. The indices do not employ leverage. You cannot invest directly in the indices.

1. Organization and Significant Accounting Policies

Pioneer Municipal High Income Advantage Fund, Inc. (the “Fund”) is organized as a Maryland corporation. Prior to April 21, 2021, the Fund was organized as a Delaware statutory trust. On April 21, 2021, the Fund redomiciled to a Maryland corporation through a statutory merger of the predecessor Delaware statutory trust with and into a newly-established Maryland corporation formed for the purpose of effecting the redomiciling. The Fund was originally organized on August 6, 2003. Prior to commencing operations on October 20, 2003, the Fund had no operations other than matters relating to its organization and registration as a diversified, closed end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The investment objective of the Fund is to seek a high level of current income exempt from regular federal income tax, and the Fund may, as a secondary objective, also seek capital appreciation to the extent that it is consistent with its primary investment objective.

Amundi Asset Management US, Inc., an indirect, wholly owned subsidiary of Amundi and Amundi’s wholly owned subsidiary, Amundi USA, Inc., serves as the Fund’s investment adviser (the “Adviser”).

In March 2020, FASB issued an Accounting Standard Update, ASU 2020-04, Reference Rate Reform (Topic 848) — Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides optional, temporary relief with respect to the financial reporting of contracts subject to certain types of modifications due to the planned discontinuation of the London Interbank Offered Rate (“LIBOR”) and other LIBOR-based reference rates at the end of 2021. The temporary relief provided by ASU 2020-04 is effective for certain reference rate-related contract modifications that occur during the period from March 12, 2020 through December 31, 2023. Management is evaluating the impact of ASU 2020-04 on the Fund's investments, derivatives, debt and other contracts, if applicable, that will undergo reference rate-related modifications as a result of the reference rate reform.

Effective August 19, 2022, the Fund is required to comply with Rule 18f-4 under the 1940 Act, which governs the use of derivatives by registered investment companies. Rule 18f-4 permits funds to enter into derivatives transactions (as defined in Rule 18f-4) and certain other transactions notwithstanding the restrictions on the issuance of “senior securities” under Section 18 of the 1940 Act. Rule 18f-4 requires a fund to establish and

32 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

maintain a comprehensive derivatives risk management program, appoint a derivatives risk manager and comply with a relative or absolute limit on fund leverage risk calculated based on value-at-risk (“VaR”), unless the fund uses derivatives in only a limited manner.

The Fund is an investment company and follows investment company accounting and reporting guidance under U.S. Generally Accepted Accounting Principles (“U.S. GAAP”). U.S. GAAP requires the management of the Fund to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of income, expenses and gain or loss on investments during the reporting period. Actual results could differ from those estimates.

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements:

A. Security Valuation

The net asset value of the Fund is computed once daily, on each day the New York Stock Exchange (“NYSE”) is open, as of the close of regular trading on the NYSE.

Fixed-income securities are valued by using prices supplied by independent pricing services, which consider such factors as market prices, market events, quotations from one or more brokers, Treasury spreads, yields, maturities and ratings, or may use a pricing matrix or other fair value methods or techniques to provide an estimated value of the security or instrument. A pricing matrix is a means of valuing a debt security on the basis of current market prices for other debt securities, historical trading patterns in the market for fixed-income securities and/or other factors. Non-U.S. debt securities that are listed on an exchange will be valued at the bid price obtained from an independent third party pricing service. When independent third party pricing services are unable to supply prices, or when prices or market quotations are considered to be unreliable, the value of that security may be determined using quotations from one or more broker-dealers.

Securities for which independent pricing services or broker-dealers are unable to supply prices or for which market prices and/or quotations are not readily available or are considered to be unreliable are valued by a fair valuation team comprised of certain personnel of the Adviser. Effective September 8, 2022, the Adviser is designated as the valuation designee for the Fund pursuant to Rule 2a-5 under the 1940 Act. The Adviser’s fair valuation team uses fair value methods approved by the Valuation Committee of the Board of Directors. The Adviser’s fair valuation team is responsible for monitoring developments that may impact fair valued securities.

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 33


 

 

 

Inputs used when applying fair value methods to value a security may include credit ratings, the financial condition of the company, current market conditions and comparable securities. The Adviser may use fair value methods if it is determined that a significant event has occurred after the close of the exchange or market on which the security trades and prior to the determination of the Fund’s net asset value. Examples of a significant event might include political or economic news, corporate restructurings, natural disasters, terrorist activity or trading halts. Thus, the valuation of the Fund’s securities may differ significantly from exchange prices, and such differences could be material.

B. Investment Income and Transactions

Interest income, including interest on income-bearing cash accounts, is recorded on the accrual basis. Dividend and interest income are reported net of unrecoverable foreign taxes withheld at the applicable country rates and net of income accrued on defaulted securities.

Discounts and premiums on purchase prices of debt securities are accreted or amortized, respectively, daily, into interest income on an effective yield to maturity basis with a corresponding increase or decrease in the cost basis of the security. Premiums and discounts related to certain mortgage backed securities are amortized or accreted in proportion to the monthly paydowns.

Interest and dividend income payable by delivery of additional shares is reclassified as PIK (payment-in-kind) income upon receipt and is included in interest and dividend income, respectively.

Security transactions are recorded as of trade date. Gains and losses on sales of investments are calculated on the identified cost method for both financial reporting and federal income tax purposes.

C. Federal Income Taxes

It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net taxable income and net realized capital gains, if any, to its shareowners. Therefore, no provision for federal income taxes is required. As of March 31, 2022, the Fund did not accrue any interest or penalties with respect to uncertain tax positions, which, if applicable, would be recorded as an income tax expense on the Statement of Operations. Tax returns filed within the prior three years remain subject to examination by federal and state tax authorities.

34 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

The amount and character of income and capital gain distributions to shareowners are determined in accordance with federal income tax rules, which may differ from U.S. GAAP. Distributions in excess of net investment income or net realized gains are temporary over distributions for financial statement purposes resulting from differences in the recognition or classification of income or distributions for financial statement and tax purposes. Capital accounts within the financial statements are adjusted for permanent book/tax differences to reflect tax character, but are not adjusted for temporary differences.

The tax character of current year distributions payable will be determined at the end of the current taxable year. The tax character of distributions paid during the year ended March 31, 2022 was as follows:

  2022
Distributions paid from:  
Tax-exempt income $12,307,435
Ordinary income 852,421
Total $13,159,856

 

The following shows the components of distributable earnings (losses) on a federal income tax basis at March 31, 2022:

  2022
Distributable earnings/(losses):  
Undistributed tax-exempt income $ 1,246,441
Capital loss carryforward (26,763,961)
Other book/tax temporary differences (956,578)
Net unrealized depreciation (2,367,567)
Total $(28,841,665)

 

The difference between book-basis and tax-basis unrealized depreciation is primarily attributable to the book/tax differences in the accrual of income on securities in default and discounts on fixed income securities.

D. Automatic Dividend Reinvestment Plan

All shareowners whose shares are registered in their own names automatically participate in the Automatic Dividend Reinvestment Plan (the “Plan”), under which participants receive all dividends and capital gain distributions (collectively, dividends) in full and fractional shares of the Fund in lieu of cash. Shareowners may elect not to participate in the Plan. Shareowners not participating in the Plan receive all dividends and capital gain distributions in cash. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by notifying American Stock Transfer & Trust Company, the agent for

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 35


 

 

 

shareowners in administering the Plan (the “Plan Agent”), in writing prior to any dividend record date; otherwise such termination or resumption will be effective with respect to any subsequently declared dividend or other distribution.

If a shareowner’s shares are held in the name of a brokerage firm, bank or other nominee, the shareowner can ask the firm or nominee to participate in the Plan on the shareowner’s behalf. If the firm or nominee does not offer the Plan, dividends will be paid in cash to the shareowner of record. A firm or nominee may reinvest a shareowner’s cash dividends in shares of the Fund on terms that differ from the terms of the Plan.

Whenever the Fund declares a dividend on shares payable in cash, participants in the Plan will receive the equivalent in shares acquired by the Plan Agent either (i) through receipt of additional unissued but authorized shares from the Fund or (ii) by purchase of outstanding shares on the New York Stock Exchange or elsewhere. If, on the payment date for any dividend, the net asset value per share is equal to or less than the market price per share plus estimated brokerage trading fees (market premium), the Plan Agent will invest the dividend amount in newly issued shares. The number of newly issued shares to be credited to each account will be determined by dividing the dollar amount of the dividend by the net asset value per share on the date the shares are issued, provided that the maximum discount from the then current market price per share on the date of issuance does not exceed 5%. If, on the payment date for any dividend, the net asset value per share is greater than the market value (market discount), the Plan Agent will invest the dividend amount in shares acquired in open-market purchases. There are no brokerage charges with respect to newly issued shares. However, each participant will pay a pro rata share of brokerage trading fees incurred with respect to the Plan Agent’s open-market purchases. Participating in the Plan does not relieve shareowners from any federal, state or local taxes which may be due on dividends paid in any taxable year. Shareowners holding Plan shares in a brokerage account may be able to transfer the shares to another broker and continue to participate in the Plan.

E. Risks

The value of securities held by the Fund may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as real or perceived adverse economic, political or regulatory conditions, inflation, changes in interest rates, armed conflict including Russia's military invasion of Ukraine, sanctions against Russia, other nations or individuals or companies and possible countermeasures, lack of liquidity in the bond markets or adverse investor sentiment. In the past several years, financial markets have experienced increased volatility, depressed valuations,

36 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

decreased liquidity and heightened uncertainty. These conditions may continue, recur, worsen or spread. In recent years, interest rates and credit spreads in the U.S. have been at historic lows. The U.S. Federal Reserve has raised certain interest rates, and interest rates may continue to go up. A general rise in interest rates could adversely affect the price and liquidity of fixed-income securities. Rates of inflation have recently risen. The value of assets or income from an investment may be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the Fund’s assets can decline as can the value of the Fund’s distributions.

The global pandemic of the novel coronavirus respiratory disease designated COVID-19 has resulted in major disruption to economies and markets around the world, including the United States. Global financial markets have experienced extreme volatility and severe losses, and trading in many instruments has been disrupted. Liquidity for many instruments has been greatly reduced for periods of time. Some sectors of the economy and individual issuers have experienced particularly large losses. These circumstances may continue to affect adversely the value and liquidity of the Fund’s investments. Following Russia’s invasion of Ukraine, Russian securities have lost all, or nearly all, their market value. Other securities or markets could be similarly affected by past or future geopolitical or other events or conditions.

Governments and central banks, including the U.S. Federal Reserve, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. These actions have resulted in significant expansion of public debt, including in the U.S. The consequences of high public debt, including its future impact on the economy and securities markets, may not be known for some time.

At times, the Fund’s investments may represent industries or industry sectors that are interrelated or have common risks, making the Fund more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors.

The municipal bond market can be susceptible to unusual volatility, particularly for lower-rated and unrated securities. Liquidity can be reduced unpredictably in response to overall economic conditions or credit tightening. Municipal issuers may be adversely affected by rising health care costs, increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. Unfavorable conditions and developments relating to projects financed with municipal securities can result in lower revenues to issuers of municipal securities, potentially resulting in defaults. Issuers often depend on revenues from these projects to make principal and interest payments. The value of municipal securities

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 37


 

 

 

can also be adversely affected by changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers, regulatory and political developments, tax law changes or other legislative actions, and by uncertainties and public perceptions concerning these and other factors. Municipal securities may be more susceptible to down-grades or defaults during recessions or similar periods of economic stress. Financial difficulties of municipal issuers may continue or get worse, particularly in the event of economic or market turmoil or a recession. To the extent the Fund invests significantly in a single state (including California and Massachusetts), city, territory (including Puerto Rico), or region, or in securities the payments on which are dependent upon a single project or source of revenues, or that relate to a sector or industry, including health care facilities, education, transportation, special revenues and pollution control, the Fund will be more susceptible to associated risks and developments.

The Fund invests in below investment grade (high yield) municipal securities. Debt securities rated below investment grade are commonly referred to as “junk bonds” and are considered speculative with respect to the issuer's capacity to pay interest and repay principal. These securities involve greater risk of loss, are subject to greater price volatility, and are less liquid, especially during periods of economic uncertainty or change, than higher rated debt securities.

The Fund’s investments, payment obligations and financing terms may be based on floating rates, such as LIBOR (London Interbank Offered Rate) or SOFR (Secured Overnight Financing Rate). ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in most major currencies. Markets are developing in response to these new rates, but questions around liquidity in these rates and how to appropriately adjust these rates to eliminate any economic value transfer at the time of transition remain a significant concern. The effect of any changes to - or discontinuation of - LIBOR on the Fund will vary depending on, among other things, existing fallback provisions in individual contracts and whether, how, and when industry participants develop and widely adopt new reference rates and fallbacks for both legacy and new products and instruments. In March, 2022, the U.S. federal government enacted legislation to establish a process for replacing LIBOR in existing contracts that do not already provide for the use of a clearly defined or practicable

38 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

replacement benchmark rate as described in the legislation. Generally speaking, for contracts that do not contain a fallback provision as described in the legislation, a benchmark replacement recommended by the Federal Reserve Board will effectively automatically replace the USD LIBOR benchmark in the contract after June 30, 2023. The recommended benchmark replacement will be based on the SOFR published by the Federal Reserve Bank of New York, including any recommended spread adjustment and benchmark replacement conforming changes. The process of transitioning may involve, among other things, increased volatility or illiquidity in markets for instruments that rely on LIBOR. The transition may also result in a reduction in the value of certain LIBOR-based investments held by the Fund or reduce the effectiveness of related transactions such as hedges. Any such effects of the transition away from LIBOR, as well as other unforeseen effects, could result in losses for the Fund. Because the usefulness of LIBOR as a benchmark may deteriorate during the transition period, these effects could occur at any time.

Russia launched a large-scale invasion of Ukraine on February 24, 2022. In response to the military action by Russia, various countries, including the U.S., the United Kingdom, and European Union issued broad-ranging economic sanctions against Russia and Belarus and certain companies and individuals. Since then, Russian securities have lost all, or nearly all, their market value, and many other issuers, securities and markets have been adversely affected. The United States and other countries may impose sanctions on other countries, companies and individuals in light of Russia’s military invasion. The extent and duration of the military action or future escalation of such hostilities, the extent and impact of existing and future sanctions, market disruptions and volatility, and the result of any diplomatic negotiations cannot be predicted. These and any related events could have a significant impact on the value and liquidity of certain Fund investments, on Fund performance and the value of an investment in the Fund, particularly with respect to securities and commodities, such as oil, natural gas and food commodities, with respect to the issuer’s capacity to pay interest and repay principal, as well as other sectors with exposure to Russian issuers or issuers in other countries affected by the invasion, and are likely to have collateral impacts on market sectors globally.

With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security and related risks. While the Fund’s Adviser has established business continuity plans in the event of, and risk management systems to prevent, limit or mitigate, such cyber-attacks, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by service providers to the Fund such as the

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 39


 

 

 

Fund’s custodian and accounting agent, and the Fund’s transfer agent. In addition, many beneficial owners of Fund shares hold them through accounts at broker-dealers, retirement platforms and other financial market participants over which neither the Fund nor the Adviser exercises control. Each of these may iturn rely on service providers to them, which are also subject to the risk of cyber-attacks. Cybersecurity failures or breaches at the Adviser or the Fund’s service providers or intermediaries have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its net asset value, impediments to trading, the inability of Fund shareowners to effect share purchases or sales or receive distributions, loss of or unauthorized access to private shareowner information and violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, or additional compliance costs. Such costs and losses may not be covered under any insurance. In addition, maintaining vigilance against cyber-attacks mainvolve substantial costs over time, and system enhancements may themselves be subject to cyber-attacks.

F. Statement of Cash Flows

Information on financial transactions which have been settled through the receipt or disbursement of cash or restricted cash is presented in the Statement of Cash Flows. Cash as presented in the Fund's Statement of Assets and Liabilities includes cash on hand at the Fund's custodian bank and does not include any short-term investments. As of and for the six months ended September 30, 2022, the Fund had no restricted cash presented on the Statement of Assets and Liabilities.

2. Management Agreement

The Adviser manages the Fund’s portfolio. Management fees payable under the Fund’s Investment Management with the Adviser are calculated daily and paid monthly at the annual rate of 0.60% of the Fund’s average daily managed assets. “Managed assets” means (a) the total assets of the Fund, including any form of investment leverage, minus (b) all accrued liabilities incurred in the normal course of operations, which shall not include any liabilities or obligations attributable to investment leverage obtained through (i) indebtedness of any type (including, without limitation, borrowing through a credit facility or the issuance of debt securities), (ii) the issuance of preferred stock or other similar preference securities, and/or (iii) any other means. For the six months September 30, 2022, the net management fee was 0.60% (annualized) of the Fund’s average daily managed assets, which was equivalent to 1.05% (annualized) of the Fund’s average daily net assets.

40 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

In addition, under the management and administration agreements, certain other services and costs, including accounting, regulatory reporting and insurance premiums, are paid by the Fund as administrative reimbursements. Included in “Due to affiliates” reflected on the Statement of Assets and Liabilities is $45,974 in management fees, administrative costs and certain other reimbursements payable to the Adviser at September 30, 2022.

3. Compensation of Directors and Officers

The Fund pays an annual fee to its Directors. The Adviser reimburses the Fund for fees paid to the Interested Directors. The Fund does not pay any salary or other compensation to its officers. For the year ended September 30, 2022, the Fund paid $9,558 in Directors’ compensation, which is reflected on the Statement of Operations as Directors’ fees. At September 30, 2022, the Fund had a payable for Directors’ fees on its Statement of Assets and Liabilities of $0.

4. Transfer Agent

American Stock Transfer & Trust Company (“AST”) serves as the transfer agent with respect to the Fund's shares. The Fund pays AST an annual fee, as is agreed to from time to time by the Fund and AST, for providing such services.

In addition, the Fund reimbursed the transfer agent for out-of-pocket expenses incurred by the transfer agent related to shareowner communications activities such as proxy and statement mailings, and outgoing phone calls.

5. Fund Shares

There are 1,000,000,000 shares of common stock of the Fund (“common shares”), $0.001 par value per share authorized.

Transactions in common shares for the six months ended September 30, 2022 and year ended March 31, 2022 were as follows:

  9/30/22 3/31/22
Shares outstanding at beginning of period 23,914,439 23,899,020
Shares outstanding at end of period 23,914,439 23,914,439

 

The Fund may classify or reclassify any unissued shares into one or more series of preferred shares.

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 41


 

 

 

As of September 30, 2022, the Fund has outstanding 1,600 Variable Rate MuniFund Term Preferred Shares Series 2021 (“series 2021 VMTP Shares” or “VMTP Shares”). The Fund issued 1,600 VMTP Shares on February 16, 2018 and 200 VMTP Shares on February 16, 2021, and redeemed 200 VMTP Shares on September 29, 2022. See Note 6 for additional information.

6. Variable Rate MuniFund Term Preferred Shares

The Fund has 1,600 shares issued and outstanding of Series 2021 VMTP Shares, with a liquidation preference of $100,000 per share. VMTP Shares are issued via private placement and are not publicly available.

The Fund is obligated to redeem its VMTP Shares by the date as specified in its offering document (“Term Redemption Date”), unless earlier redeemed by the Fund. VMTP Shares are subject to optional and mandatory redemption in certain circumstances. The VMTP Shares may be redeemed at the option of the Fund, subject to payment of premium for approximately one year following the date of issuance (“Optional Redemption Date”), and at the redemption price per share thereafter. The redemption price per share is equal to the sum of the liquidation preference per share plus any accumulated but unpaid dividends. The Fund may be obligated to redeem a certain amount of the VMTP Shares if it fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The Term Redemption Date for the Fund’s Series 2021 VMTP Shares was extended from August 2, 2021 to August 2, 2024 in February 2021. Six months prior to Term Redemption Date, the Fund is required to segregate liquid assets with the Fund’s custodian to fund the redemption in an amount equal to at least 100% of the term redemption amount.

VMTP Shares are subject to restrictions on transfer, generally do not trade, and market quotations are generally not available. VMTP Shares are short-term or short/intermediate-term instruments that pay a variable dividend rate tied to a short-term index, plus an additional fixed “spread” amount established at the time of issuance. For financial reporting purposes, the liquidation preference of VMTP Shares is a liability and is recognized as a component of “Variable Rate MuniFund Term Preferred Shares” on the Statement of Assets and Liabilities since the shares have a stated mandatory redemption date.

Dividends on the VMTP Shares (which are treated as interest payments for financial reporting purposes and are recorded as interest expense on the Statement of Operations) are declared daily, paid monthly and recorded as incurred. For the six months ended September 30, 2022, interest expense on VMTP Shares amounted to $1,820,325. The dividend rate for the VMTP Shares is determined weekly. Unpaid dividends on VMTP Shares are

42 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

recognized as “Interest Expense Payable” on the Statement of Assets and Liabilities. For the six months ended September 30, 2022, there was no interest expense payable on VMTP Shares. From April 30, 2022 through September 30, 2022, the Series 2021 VMTP Shares paid an average dividend rate of 2.01% and the average liquidation value outstanding of VMTP Shares for the Fund during the six months ended September 30, 2022, was $179,781,421.

The Fund did not incur any offering costs as a result of the offerings on February 16, 2018 and February 16, 2021.

Transactions in the Series 2021 VMTP Shares during the Fund’s current and prior reporting periods were as follows:

         
  Period Ended 9/30/22 Year Ended 3/31/22
  Shares Amount Shares Amount

Approval of Renewal of Investment Management Agreement

Amundi Asset Management US, Inc. (“Amundi US”) serves as the investment adviser to Pioneer Municipal High Income Advantage Fund, Inc. (the “Fund”) pursuant to an investment management agreement between Amundi US and the Fund. In order for Amundi US to remain the investment adviser of the Fund, the Directors of the Fund, including a majority of the Fund’s Independent Directors, must determine annually whether to renew the investment management agreement for the Fund.

The contract review process began in January 2022 as the Directors of the Fund agreed on, among other things, an overall approach and timeline for the process. Contract review materials were provided to the Directors in March 2022, July 2022 and September 2022. In addition, the Directors reviewed and discussed the Fund’s performance at regularly scheduled meetings throughout the year, and took into account other information related to the Fund provided to the Directors at regularly scheduled meetings, in connection with the review of the Fund’s investment management agreement.

In March 2022, the Directors, among other things, discussed the memorandum provided by Fund counsel that summarized the legal standards and other considerations that are relevant to the Directors in their deliberations regarding the renewal of the investment management agreement, and reviewed and discussed the qualifications of the investment management teams for the Fund, as well as the level of investment by the Fund’s portfolio managers in the Fund. In July 2022, the Directors, among other things, reviewed the Fund’s management fees and total expense ratios, the financial statements of Amundi US and its parent companies, profitability analyses provided by Amundi US, and analyses from Amundi US as to possible economies of scale. The Directors also reviewed the profitability of the institutional business of Amundi US as compared to that of Amundi US’s fund management business, and considered the differences between the fees and expenses of the Fund and the fees and expenses of Amundi US’s institutional accounts, as well as the different services provided by Amundi US to the Fund and to the institutional accounts. The Directors further considered contract review materials, including additional materials received in response to the Directors’ request, in September 2022.

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 45


 

 

 

At a meeting held on September 20, 2022, based on their evaluation of the information provided by Amundi US and third parties, the Directors of the Fund, including the Independent Directors voting separately advised by independent counsel, unanimously approved the renewal of the investment management agreement for another year. In approving the renewal of the investment management agreement, the Directors considered various factors that they determined were relevant, including the factors described below. The Directors did not identify any single factor as the controlling factor in determining to approve the renewal of the agreement.

Nature, Extent and Quality of Services

The Directors considered the nature, extent and quality of the services that had been provided by Amundi US to the Fund, taking into account the investment objective and strategy of the Fund. The Directors also reviewed Amundi US’s investment approach for the Fund and its research process. The Directors considered the resources of Amundi US and the personnel of Amundi US who provide investment management services to the Fund. They also reviewed the amount of non-Fund assets managed by the portfolio managers of the Fund. They considered the non-investment resources and personnel of Amundi US that are involved in Amundi US’s services to the Fund, including Amundi US’s compliance, risk management, and legal resources and personnel. The Directors noted the substantial attention and high priority given by Amundi US’s senior management to the Pioneer Fund complex, including with respect to the increasing regulation to which the Pioneer Funds are subject. The Directors considered the effectiveness of Amundi US’s business continuity plan in response to the ongoing COVID-19 pandemic.

The Directors considered that Amundi US supervises and monitors the performance of the Fund’s service providers and provides the Fund with personnel (including Fund officers) and other resources that are necessary for the Fund’s business management and operations. The Directors also considered that, as administrator, Amundi US is responsible for the administration of the Fund’s business and other affairs. The Directors considered that the Fund reimburses Amundi US its pro rata share of Amundi US’s costs of providing administration services to the Pioneer Funds.

Based on these considerations, the Directors concluded that the nature, extent and quality of services that had been provided by Amundi US to the Fund were satisfactory and consistent with the terms of the investment management agreement.

Performance of the Fund

In considering the Fund’s performance, the Directors regularly review and discuss throughout the year data prepared by Amundi US and information comparing the Fund’s performance with the performance of its peer group of funds, as classified by Morningstar, Inc. (Morningstar), and with the performance of the Fund’s benchmark index. The Directors also regularly consider the Fund’s returns at market value relative to its peers, as well as the discount at which the Fund’s shares may trade on the New York Stock Exchange compared to its net asset value per share. They also discuss the Fund’s performance with Amundi US on a regular basis. The Directors’ regular reviews and discussions were factored into the Directors’ deliberations concerning the renewal of the investment management agreement.

Management Fee and Expenses

The Directors considered information showing the fees and expenses of the Fund in comparison to the management fees and expense ratios of a peer group of funds selected on the basis of criteria determined by the Independent Directors for this purpose using data provided by Strategic Insight Mutual Fund Research and Consulting, LLC (Strategic Insight), an independent third party. The peer group comparisons referred to below are organized in quintiles. Each quintile represents one-fifth of the peer group. In all peer group comparisons referred to below, first quintile is most favorable to the Fund’s shareowners.

The Directors considered that the Fund’s management fee (based on managed assets) for the most recent fiscal year was in the second quintile relative to the management fees paid by other funds in its Strategic Insight peer group for the comparable period. The Directors considered that the expense ratio (based on managed assets) of the Fund’s common shares for the most recent fiscal year (both including and excluding investment-related expenses) was in the third quintile relative to its Strategic Insight peer group for the comparable period.

The Directors reviewed management fees charged by Amundi US to institutional and other clients, including publicly offered European funds sponsored by Amundi US’s affiliates, unaffiliated U.S. registered investment companies (in a sub-advisory capacity), and unaffiliated foreign and domestic separate accounts. The Directors also considered Amundi US’s costs in providing services to the Fund and Amundi US’s costs in providing services to the other clients and considered the differences in management fees and profit margins for fund and non-fund services. In evaluating the

Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22 47


 

 

 

fees associated with Amundi US’s client accounts, the Directors took into account the respective demands, resources and complexity associated with the Fund and other client accounts. The Directors noted that, in some instances, the fee rates for those clients were lower than the management fee for the Fund and considered that, under the investment management and administration agreements with the Fund, Amundi US performs additional services for the Fund that it does not provide to those other clients or services that are broader in scope, including oversight of the Fund’s other service providers and activities related to compliance and the extensive regulatory and tax regimes to which the Fund is subject. The Directors also considered the entrepreneurial risks associated with Amundi US’s management of the Fund.

The Directors concluded that the management fee payable by the Fund to Amundi US was reasonable in relation to the nature and quality of the services provided by Amundi US.

Profitability

The Directors considered information provided by Amundi US regarding the profitability of Amundi US with respect to the advisory services provided by Amundi US to the Fund, including the methodology used by Amundi US in allocating certain of its costs to the management of the Fund. The Directors also considered Amundi US’s profit margin in connection with the overall operation of the Fund. They further reviewed the financial results, including the profit margins, realized by Amundi US from non-fund businesses. The Directors considered Amundi US’s profit margins in comparison to the limited industry data available and noted that the profitability of any adviser was affected by numerous factors, including its organizational structure and method for allocating expenses. The Directors concluded that Amundi US’s profitability with respect to the management of the Fund was not unreasonable.

Economies of Scale

The Directors considered the extent to which Amundi US may realize economies of scale or other efficiencies in managing and supporting the Fund. Since the Fund is a closed-end fund that has not raised additional capital, the Directors concluded that economies of scale were not a relevant consideration in the renewal of the investment advisory agreement.

48 Pioneer Municipal High Income Advantage Fund, Inc. | Semiannual Report | 9/30/22


 

 

 

Other Benefits

The Directors considered the other benefits that Amundi US enjoys from its relationship with the Fund. The Directors considered the character and amount of fees paid or to be paid by the Fund, other than under the investment management agreement, for services provided by Amundi US and its affiliates. The Directors further considered the revenues and profitability of Amundi US’s businesses other than the Fund business. To the extent applicable, the Directors also considered the benefits to the Fund and to Amundi US and its affiliates from the use of “soft” commission dollars generated by the Fund to pay for research and brokerage services.

The Directors considered that Amundi US is the principal U.S. asset management business of Amundi, which is one of the largest asset managers globally. Amundi’s worldwide asset management business manages over $2.2 trillion in assets (including the Pioneer Funds). The Directors considered that Amundi US’s relationship with Amundi creates potential opportunities for Amundi US and Amundi that derive from Amundi US’s relationships with the Fund, including Amundi’s ability to market the services of Amundi US globally. The Directors noted that Amundi US has access to additional research and portfolio management capabilities as a result of its relationship with Amundi and Amundi’s enhanced global presence that may contribute to an increase in the resources available to Amundi US. The Directors considered that Amundi US and the Fund receive reciprocal intangible benefits from the relationship, including mutual brand recognition and, for the Fund, direct and indirect access to the resources of a large global asset manager. The Directors concluded that any such benefits received by Amundi US as a result of its relationship with the Fund were reasonable.

Conclusion

After consideration of the factors described above as well as other factors, the Directors, including the Independent Directors, concluded that the investment management agreement for the Fund, including the fees payable thereunder, was fair and reasonable and voted to approve the proposed renewal of the investment management agreement.

PIONEER FUNDS

APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES

PROVIDED BY THE INDEPENDENT AUDITOR

 

SECTION I - POLICY PURPOSE AND APPLICABILITY

 

The Pioneer Funds recognize the importance of maintaining the independence of their outside auditors. Maintaining independence is a shared responsibility involving Amundi Asset Management US, Inc., the audit committee and the independent auditors.

 

The Funds recognize that a Fund’s independent auditors: 1) possess knowledge of the Funds, 2) are able to incorporate certain services into the scope of the audit, thereby avoiding redundant work, cost and disruption of Fund personnel and processes, and 3) have expertise that has value to the Funds. As a result, there are situations where it is desirable to use the Fund’s independent auditors for services in addition to the annual audit and where the potential for conflicts of interests are minimal. Consequently, this policy, which is intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and procedures to be followed by the Funds when retaining the independent audit firm to perform audit, audit-related tax and other services under those circumstances, while also maintaining independence.

 

Approval of a service in accordance with this policy for a Fund shall also constitute approval for any other Fund whose pre-approval is required pursuant to Rule 210.2-01(c)(7)(ii).

 

In addition to the procedures set forth in this policy, any non-audit services that may be provided consistently with Rule 210.2-01 may be approved by the Audit Committee itself and any pre-approval that may be waived in accordance with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

 

Selection of a Fund’s independent auditors and their compensation shall be determined by the Audit Committee and shall not be subject to this policy.
