30-Day SEC Yield (Subsidized/Unsubsidized): Represents net investment income earned by a fund over a 30-day period, expressed as an annual percentage rate based on the fund's share price at the end of the 30-day period. Subsidized yield reflects fee waivers and/or expense reimbursements during the period. Without waivers and/or reimbursements, yields would be reduced. Unsubsidized yield does not adjust for any fee waivers and/or expense reimbursements in effect.
Yield to Worst: Lowest yield possible for a security given the current price, taking into account both call dates and maturity.
Yield to Maturity: The internal rate of return of the security based on the given market price—it is the single discount rate that equates a security price (inclusive of accrued interest) with its projected cashflows.
Past performance is no guarantee of future results. Investment returns will fluctuate and it is possible to lose money.
