Nuveen outlines how a proposed merger into Nuveen Municipal High Income Opportunity Fund (NMZ) would affect shareholders of NXJ, NQP and another state-specific municipal fund. The key focus is the loss of state tax exemption versus changes in earnings yields.
As of July 31, 2025, common earnings yields were 3.30% for NXJ, 3.54% for NQP and 3.32% for the other fund, compared with a 6.17% common earnings yield for NMZ post-merger, implying increases of 2.87%, 2.63% and 2.85%. After adjusting for each state’s maximum tax rate, state tax adjusted equivalent rates were 3.70%, 3.65% and 3.49% versus NMZ’s 6.17%, still showing gains of 2.47%, 2.52% and 2.68%. The funds state that shareholders would experience no negative impact from losing state tax exemption on earnings because NMZ’s higher yield more than offsets it.
Nuveen’s proposal to merge several state-specific municipal funds into Nuveen Municipal High Income Opportunity Fund (NMZ) compares after-tax earnings for shareholders who would lose state tax exemption. Using industry convention, yields for NXJ, NQP, and the Missouri fund are “grossed up” by each state’s maximum tax rate.
As of July 31, 2025, common earnings yields were 3.30% for NXJ, 3.54% for NQP, 3.32% for the Missouri fund, and 6.17% for NMZ. On a state tax adjusted equivalent basis, these become 3.70%, 3.65%, and 3.49% versus NMZ’s 6.17%. The table shows gains of about 2.5 percentage points in state tax adjusted equivalent rates for each state fund, indicating higher earnings even after losing state tax exemption.
