Although we have no reason to believe the information concerning the underlying securities or the underlying securities issuer contained in the underlying securities issuer’s Exchange Act reports is not reliable, neither the depositor nor the trustee participated in the preparation of such documents or made any due diligence inquiry with respect to the information provided therein. No investigation with respect to the underlying securities issuer (including, without limitation, no investigation as to its financial condition or creditworthiness) or of the underlying securities has been made. You should obtain and evaluate the same information concerning the underlying securities issuer as you would obtain and evaluate if your investment were directly in the underlying securities or in other securities issued by the underlying securities issuer. There can be no assurance that events affecting the underlying securities or the underlying securities issuer have not occurred or have not yet been publicly disclosed which would affect the accuracy or completeness of the publicly available documents described above.
