* Annualized. Yield is a more accurate reflection of the Fund's current earnings than total return.
The 7-day yields refer to the income generated by an investment in the Fund over a 7-day period. This income is then annualized. The 7-day effective yield is calculated similarly, but the income earned is assumed to have been reinvested. The effective yield will be slightly higher than the current yield because of the compounding effect of this assumed reinvestment .
