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.

The management fee has been restated to reflect the decrease in the management fee effective August 1, 2023. Returns or yields for the fund would have been lower if a portion of the management fee had not been waived. Review the annual or semiannual report for the most current information.
The advisor has agreed to waive the G Class's management fee in its entirety. The advisor expects this fee waiver to remain in effect permanently and cannot terminate it without the approval of the Board of Trustees.
