Nuveen AMT-Free Municipal Income Fund (the Fund) is a closed-end Fund. The fund's investment objectives are to provide current income exempt from regular federal income tax and the alternative minimum tax applicable to individuals and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal bonds that the fund's investment adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

The fund invests at least 80% of its managed assets in municipal securities rated, at the time of investment, investment grade (Baa/BBB or better by S&P, Moody�s, or Fitch) or, if they are unrated, are judged by the manager to be of comparable quality.
