~~Item~~ Not 4applicable.~~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 TWC-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.
