Nuveen Texas Quality Municipal Income Fund, formerly Nuveen Texas Quality Income Municipal Fund, is a diversified closed-end management investment company. The Fund seeks to provide current income exempt from both regular federal and designated state income taxes by investing primarily in a portfolio of municipal obligations issued by state and local government authorities within a single state or certain the United States territories. It invests approximately 80% of its managed assets in 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. It may invest over 20% of its managed assets in municipal securities rated below investment quality or judged by the manager to be of comparable quality, of which up to 10% of its managed assets may be rated below B-/B3 or of comparable quality.
