AI brief of an SEC Form 8-K · NUVEEN MUNICIPAL HIGH INCOME OPPORTUNITY FUND (NMZ)

Nuveen Municipal High Income Opportunity Fund suspends control share by-law after court ruling

Neutral Impact 4 of 5 legal/regulatory Written later

The fund's board amended its by-laws on February 24, 2022, so the control share provision is of no force and effect while a U.S. District Court judgment in favor of Saba Capital is in effect. If that judgment is reversed or nullified, the provision would be automatically reinstated, and the board said it intends to appeal. The change affects how shareholders who acquire large stakes in the fund could be allowed to vote.

Key points

  • Board adopted Amendment No. 1 to the by-laws on February 24, 2022.
  • District Court granted summary judgment in favor of Saba on February 18, 2022, on claims for rescission and declaratory judgment.
  • The Board and the Funds intend to appeal the District Court's decision.
  • The amendment applies to multiple Nuveen closed-end funds, including Nuveen Municipal High Income Opportunity Fund (NYSE: NMZ).
