Fund may underperform the return of the Underlying Index for a number of reasons, including, for example, (i) the performance of investments or derivatives related to the Underlying Index may not correlate with the Underlying Index and/or may underperform the Index due to transaction costs, fees, or other aspects of the transaction’s pricing; (ii) the Fund may not be able to find counterparties willing to enter into derivative instruments whose returns are based on the return of the Underlying Index or find parties who are willing to do so at an acceptable cost or level of risk to the Fund; and (iii) errors may arise in carrying out the Underlying Index’s methodology, or the Index Provider may incorrectly report information concerning the Index.
