<sup>1</sup> On July 15, 2025, the Series' secondary benchmark changed from the FTSE 3-Month Treasury Bill Index to the ICE BofA US 3-Month Treasury Bill Index. The Advisor considers the ICE BofA US 3-Month Treasury Bill Index an appropriate cash proxy that aligns with the strategy's investment objective and is more widely used in the marketplace than the FTSE 3-Month Treasury Bill Index.
