In plain terms — Aberdeen Municipal Income Fund
Shares currently cost about 8.6% less than the value of the assets behind them (a discount).
Over the past year it has averaged a 9.3% discount, so today's level is not high for this fund (Z-score +1.0). That describes the past; it does not predict where the discount goes next.
It pays regular distributions worth about 7.2% a year of the share price (6.6% of the assets). That is a payout rate, not a return: part of it may be capital being handed back.
Because the shares trade below the value of their assets, each dollar of reinvested distributions buys about $1.09 of assets — a ReinvestCapture™ rate of 7.9%, more than the payout rate itself. That is buying power, not a return.
The assets themselves fell 4.2% over the past year including distributions (NAV total return).
