A calculation based on a 30-day period ending on the last of the previous month. It is computed by dividing the net investment income per share earned during the period by the maximum offering price per share on the last day of the period. The figure listed lags by one month. When a dash appears, the yield available is more than 30 days old. This information is taken from fund surveys.

b = expenses accrued for the periods (net of reimbursements)
c = the average daily number of shares outstanding during the period, that were entitled to receive dividends
d = the maximum offering price per share on the last day of the period
Income = the sum of the trailing 12-month income dividends
Capital gains = the sum of the trailing 12-month capital gains
