Pioneer AMT-Free Municipal Fund


  • Actively managed multi-sector bond fund that applies a consistent, value-oriented total return approach

  • Avoids investing in securities whose interest is subject to the alternative minimum tax (AMT)

  • Invests in a nationally diversified portfolio of municipal bonds seeking to enhance liquidity and risk/return potential versus individual issues and state-specific investments

  • Focuses on a research-driven approach to uncover attractive relative values and quality issues with competitive yields. Fund manager David Eurkus sticks to a disciplined strategy of buying long-term bonds that run very little risk of being called

  • * Past performance cannot guarantee future results



The Fund seeks to maximize current income exempt from federal income taxes, consistent with the preservation of capital, primarily through investment-grade tax-exempt bonds. The Fund invests in a nationally diversified portfolio of municipal bonds.

Diversification does not assure a profit or protect against loss.


"We stay fully invested in long-term, nationally diversified, investment grade municipal bonds. We like to take positions in bonds which are temporarily undervalued, thereby potentially enhancing total return when conditions are corrected."

Fund commentary with performance analysis


When interest rates rise, the prices of fixed-income securities in the Fund will generally fall. Conversely, when interest rates fall, the prices of fixed-income securities in the Fund will generally rise. Investments in the fund are subject to possible loss due to the financial failure of issuers of underlying securities and their inability to meet their debt obligations. At times, the Fund's investments may represent industries or industry sectors that are interrelated or have common risks, making it more susceptible to any economic, political, or regulatory developments or other risks affecting those industries and sectors. The value of municipal securities can be adversely affected by changes in financial condition of municipal issuers, lower revenues, and regulatory and political developments. A portion of income may be subject to local, state, federal, and/or alternative minimum tax. Capital gains, if any, are subject to a capital gains tax. These risks may increase share price volatility.

Fund Facts

As of May 31, 2016

(load waived) (load adjusted)
Overall Morningstar RatingTM
(out of 187 funds in the Muni National Long Category)

Morningstar proprietary ratings reflect risk-adjusted performance as of 5/31/16

The Overall Morningstar RatingTM is based on a weighted average of the star ratings assigned to a fund's three, five, and ten year (as applicable) time periods. The Morningstar Category identifies funds based on their underlying portfolio holdings. Classifications are based on portfolio statistics and compositions over the past three years. For funds less than three years old, category classifications are based on life of the fund. Pioneer AMT-Free Municipal Fund was rated exclusively against U.S.-domiciled muni national long funds as follows: 4, 5 and 5 stars (load waived) and 3, 4 and 3 stars (load adjusted) among 187, 175 and 147 funds for the three-, five-, and 10-year periods ended 5/31/16, respectively. The Morningstar Rating is for Class A Shares only. Morningstar Load Waived ratings do not take into account Class A sales charges. Ratings may vary among share classes and are based on past performance, which is no guarantee of future results.

Please see a prospectus for complete information pertaining to load waived eligibility (such as large purchases or certain types of group plan participants). For each fund with at least a three-year history, Morningstar calculates a Morningstar Rating based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. Within each asset class, the top 10%, the next 22.5%, 35%, 22.5%, and the bottom 10% receive 5, 4, 3, 2, or 1 star, respectively. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) Each fund is rated exclusively against U.S. domiciled funds. The following copyright pertains only to Morningstar information.

30-day SEC yield is based on the hypothetical annualized earning power (investment income only) of the Fund's portfolio securities during the period indicated. Duration is a measurement of how long, in years, it takes for the price of a bond to be repaid by its internal cash flows.

The Average Maturity of certain funds might not be a useful measure if they contain securities with principal paydowns, such as mortgage passthroughs. Instead, market participants calculate Average Life, which reflects the average time to receipt of principal payments (scheduled principal payments and projected prepayments).
