The Nuveen AMT-Free Municipal Credit Income Fund (NVG) operates as a closed-end investment vehicle, initially launched by Nuveen Investments, Inc. Its oversight is a collaborative effort between Nuveen Fund Advisors LLC and Nuveen Asset Management, LLC. The fund primarily allocates capital within the U.S. fixed income sector, concentrating on undervalued municipal debt instruments and associated investments that offer exemptions from standard federal income taxes. Holdings must possess a credit rating of at least Baa/BBB from S&P, Moody's, or Fitch, and the portfolio maintains an average maturity of 17.02 years. Its investment strategy employs a bottom-up security selection method combined with fundamental analysis. Performance is measured against the Standard & Poor's (S&P) Insured Municipal Bond Index. The fund previously traded as the Nuveen Insured Dividend Advantage Municipal Fund and the Nuveen Enhanced AMT-Free Municipal Credit Opportunities Fund. NVG was established on July 12, 1999, and is domiciled in the United States.
