Data quoted represents past performance which is no guarantee of future results. Due to market conditions, current yields may be higher or lower than the yields shown.

Distribution Rate is the most recent dividend per share (annualized) divided by the respective price per share. The SEC 30-Day Yield is a standardized measure of the current market yield on the Fund’s portfolio and is based on the maximum offering price per share as of the date specified. The Distribution Rate also differs from the SEC 30-Day Yield because the Fund may be paying out more or less than it is earning and it may not include the effect of amortization of bond premium. The SEC 30-Day Yield on A Shares at NAV applies only to A Shares purchased at no-load pursuant to the Fund’s policy permitting waiver of the A Share load in certain specified circumstances.
