Business Context and Reporting Period
This Form 8-K was filed by Nuveen Municipal High Income Opportunity Fund on August 5, 2016. The report details an "Other Event" (Item 8.01) regarding a revision to the fund's investment policy effective August 5, 2016. The change aligns the fund with a broader strategy across Nuveen's municipal closed-end fund complex to standardize exposure limits to securities subject to the federal Alternative Minimum Tax (AMT).
Key Financial Metrics
The filing text does not provide specific financial performance data such as revenue, profit, cash flow, margins, debt, or liquidity metrics. The document focuses exclusively on the modification of investment policy parameters.
Material Changes Versus Prior Period
The primary material change is the revision of the fund's investment policy regarding AMT securities:
- Prior Policy: The fund previously had a limit of 30% on managed assets invested in securities subject to AMT.
- New Policy: The fund has adopted a new limit of no more than 20% of managed assets in securities subject to AMT.
- Context: This change replaces the old policy to create a uniform 20% limit across Nuveen's municipal complex. While some funds previously had no limit, others had a 30% limit; all are now standardized to 20%.
