Returns are historical and are calculated by determining the percentage change in net asset value (NAV) with all distributions reinvested. The Fund's past performance is no guarantee of future results. Investment return and principal value of Fund shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Performance is for the stated time period only; due to market volatility, the Fund's current performance may be lower or higher than the quoted return. Performance less than one year is cumulative.

Funds listed below include only those paying monthly distributions.

1 SEC 30-Day Yield is calculated by dividing the net investment income per share for the 30-day period by the maximum offering price at the end of the period and annualizing the result. Subsidized yield reflects the effect of fee waivers and expense reimbursements.

2 The Distribution Rate is based on the Fund’s most recent monthly distribution per share (annualized) divided by the Fund’s NAV or market price at the end of the period. The Fund's monthly distribution may be comprised of ordinary income, net realized capital gains and returns of capital.
