Item 8.01		Other events

	Exercise of call warrants and final distributions to holders of the PPLUS Trust Certificates Series CSF-1 on July 14, 2010 and July 15, 2010. On June 14, 2010, we received a notice of exercise from the holder of the call warrants for PPLUS Trust Certificates Series CSF-1, which specified that the call warrant holder intended to exercise its warrants in full and call all outstanding trust certificates. On July 14, 2010, the exercise date of the call warrants, we distributed the aggregate exercise price of $30,932,291.67 (representing, with respect to the Class A trust certificates, $30,000,000 with respect to the principal amount and $932,291.67 with respect to the interest amount). The call warrantholder was already the sole owner of all

outstanding Class B trust certificates and as a result, no separate exercise price was required with respect to the Class B trust certificates.

On July 15, 2010, the call warrantholder effected an optional exchange and exchanged all of the outstanding PPLUS Trust Certificates Series CSF-1 for the underlying securities held by the trust. The interest payment received on the underlying securities in an aggregate amount of $1,068,750 was distributed to the call warrantholder as sole holder of the trust certificates.

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.
