Nuveen updates 80% municipal-bond investment policy, shareholder approval rules clarified
Nuveen updated its investment policy to require at least 80% of assets in municipal bonds that provide income, effective October 30, 2026. The policy change, adopted under Rule 35d-1, can be altered by the board with 60 days' notice, but changes to the 80% threshold require shareholder approval. The fund will invest primarily in federally tax-exempt municipal securities.
