	For information with respect to the underlying securities held by PPLUS Trust Series CMT-1, please refer to Comcast Corporation’s (Commission file number 000-50093) periodic reports, including annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K, and other information on file with the Securities and Exchange Commission (the “SEC”).

You may obtain copies of this material for a fee by writing to the SEC’s Public Reference Section of the SEC at 100 F Street, NE, Washington, D.C. 20549. You may obtain information about the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. You can also access some of this information electronically by means of the SEC’s website on the Internet at http://www.sec.gov, which contains reports, proxy and information statements and other information that the underlying securities guarantors’ and underlying securities issuer have filed electronically with the SEC.
	Although we have no reason to believe the information concerning the underlying securities, the underlying guarantees, the underlying securities issuer or the underlying securities guarantors contained in the underlying securities issuer’s or the underlying securities guarantors’ 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 or the underlying securities guarantors (including, without limitation, no investigation as to their respective financial condition or creditworthiness), the underlying securities or the underlying guarantees has been made. You should obtain and evaluate the same information concerning the underlying securities issuer and the underlying securities guarantors as you would obtain and evaluate if you were investing directly in the underlying securities and the underlying guarantees or in other securities issued by the underlying securities issuer or the underlying securities guarantors. There can be no assurance that events affecting the underlying securities, the underlying guarantees, the underlying securities issuer or the underlying securities guarantors have not occurred or have not yet been publicly disclosed which would affect the accuracy or completeness of the publicly available documents described above.
