## Bond fund yield calculation

30-day yield, Wikipedia

The formula for SEC 30-day yield is

Where:

- a = dividends and interest collected during the past 30 days
- b = accrued expenses of the past 30 days
- c = average daily number of outstanding shares that were entitled to distributions
- d = the maximum public offering price per share on the last day of the period

Including the formula in this form might be useful, but it needs clarification. In particular, this formula from Wikipedia does not explain that the income for a bond is based on yield to maturity (or to call); if a bond rises in price, the value of a will be less than the coupon payment. I was hoping to find a more official SEC page giving the full SEC definitions.
