Fund net investment income per common share; actual reporting period, not annualized$0.2800

For the six months ended April 30, 2026, NMZ reported $0.28 of net investment income and $0.39 of distributions per share. Net asset value fell from $10.61 to $10.37. This half-year crosses the April 2026 fund mergers, so it belongs on its own rather than being joined to the five complete pre-merger years as one unchanged strategy trend.

Cash distributions and reported returns

Cash distributions are the total paid per share during each reporting period, including any gains or return of capital. Period lengths may differ, so compare the dates before comparing amounts. Short periods are not annualized.

NAV change excludes distributions. Reported NAV total return includes reinvestment and is copied from the fund statement, not estimated by adding cash distributions to the NAV change.

Why the annual trend is limited

The income and distribution trend ends with fiscal 2025 because NMZ absorbed three municipal funds in April 2026. The six months ended April 2026 include that change and are not another comparable full year. Follow the next complete post-merger report to judge the current portfolio's income support.

Distribution and NAV evidence

Cash paid, opening and closing NAV, and the fund-reported NAV total return are separate observations. NAV change excludes distributions. These figures show outcomes, not which source funded a payment or whether future distributions are sustainable. Net investment income excludes investment gains and is not a payout-coverage ratio.

The assets behind the earnings

How NMZ makes money

Financial snapshot: 2026-04-30. Research reviewed 2026-09-18. Source dates are retained with each measure; historical results are not a forecast.

The income-producing business

Bond interest, less expenses and financing costs, is the central recurring income source. A declared distribution can include gains or return of capital as well as investment income; its amount is not an earnings figure.

The earnings available to shareholders depend on the cash generated by these activities after operating and financing costs. Portfolio gains, financing proceeds and recurring income should be evaluated separately.
