~~Not applicable~~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

~~Section~~outstanding 2Class B trust certificates and as a result, no separate exercise price was required with respect to the Class B trust certificates. ~~Financial~~ ~~Information~~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.

Item 4.01 Changes in Registrant’s Certifying Accountant.

(a) On March 3, 2010, Deloitte & Touche LLP (“D&T”) informed the Board of Directors of Merrill Lynch Depositor, Inc. (the “Registrant”) that it has declined to stand for reappointment as the Registrant’s independent registered public accounting firm in examining management’s assertion that the Registrant has complied with its minimum servicing standards.

D&T’s reports with respect to the examination of management’s assertion that the Registrant has complied with its established minimum servicing standards with respect to PPLUS Trust Series CSF-1 (the “Trust”) for the fiscal years ended December 31, 2008 and December 31, 2007 did not contain an adverse opinion or a disclaimer of opinion. While the scope of D&T’s examination was limited to the Registrant’s compliance with the minimum servicing standards, there were no further qualifications regarding audit scope, uncertainty or servicing standards. During the Trust’s fiscal years ended December 31, 2008 and December 31, 2007 and during the period from January 1, 2009 through March 3, 2010, there were no disagreements with D&T on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of D&T, would have caused it to make a reference to the subject matter thereof in its report on management’s assertion that the Registrant has complied with its established minimum servicing standards for such periods. During the Trust’s fiscal years ended December 31, 2008 and December 31, 2007 and during the period from January 1, 2009 through March 3, 2010, there were no “reportable events” (as defined in Regulation S-K Item 304(a)(1)(v)).

The Registrant has provided D&T with a copy of the foregoing disclosures and has requested that D&T furnish it with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made by the Registrant set forth above. A copy of D&T’s letter dated March 4, 2010 is filed as Exhibit 16.1 to this Form 8-K.

(b) On March 4, 2010, the Registrant approved the engagement of PricewaterhouseCoopers LLP (“PwC”) to replace D&T as the Registrant’s independent registered public accounting firm for examining management’s assertion that the Registrant has complied with its minimum servicing standards.

During the Trust’s fiscal years ended December 31, 2008 and December 31, 2007 and during the period from January 1, 2009 through March 3, 2010, neither the Registrant, the Trust, nor anyone on their behalf consulted PwC, on behalf of the Registrant or the Trust, regarding the application of accounting principles to a specified transaction (either completed or proposed), the type of report that might be rendered on management’s assertion that the Registrant has complied with its minimum servicing standards, or any matter that was either the subject of a “disagreement,” as defined in Item 304(a)(1)(iv) of Regulation S-K and the instructions thereto, or a “reportable event,” as defined in Item 304(a)(1)(v) of Regulation S-K.
