The Fund would then be forced to reinvest the unanticipated proceeds at lower interest rates, resulting in a decline in the Fund’s income.• High-Yield (junk) bond risk.

The Fund may invest in derivatives, which may involve risks different from, and possibly greater than, those of investments directly in the underlying securities or assets.• Counterparty risk. This is the chance that the counterparty to a derivatives contract, or other investment vehicle, with the Fund is unable or unwilling to meet its financial obligations.Because the Fund is an exchange-traded fund (ETF) and the Fund’s shares are traded on an exchange, the Fund is subject to additional risks:
