Autocallable Structure Risk –The Fund’s returns are correlated to the performance of a synthetic portfolio of autocallable notes tracked by the Laddered Autocall Index. Autocallable notes have specific structural features that may be unfamiliar to many investors:

–Contingent Income Risk: Coupon payments from the Autocalls are not guaranteed and will not be made if the Underlying Index falls below the Coupon Barrier on observation dates. This means the Fund may generate significantly less income than anticipated during market downturns.

–Early Redemption Risk: Autocalls in the Portfolio may be called before their scheduled maturity if the Underlying Reference Index reaches or exceeds the Autocall Barrier on observation dates. This automatic early redemption could force reinvestment of that portion of the portfolio at lower rates if market yields have declined.

–Barrier Risk: If the Underlying Reference Index falls below the Protection Level Barrier at the maturity of an Autocall in the Portfolio, that portion of the Portfolio will be fully exposed to the negative performance of the Underlying Reference Index from its initial level. This conditional protection creates a binary outcome that can result in sudden, significant losses if barriers are breached.
