Please note that our limited review covers only those issues addressed in the comments below. Please also note that our comments to either the base prospectus and/or the supplements should be applied universally, if applicable. Page references are to the marked copies you provided to us. Registration Statement on Form S-3 General 1. While we note your response to prior comment 1 of our letter dated March 30, 2006, please clearly confirm that you will file unqualified legal and tax opinions at the time of each takedown. 2. When referring to transaction parties, please use the terminology set out in Regulation AB. For example, we note that while you have used the term "issuing entity" in some places, you still refer to the "issuance trust" on the cover of the prospectus supplements and on page 1 of your base prospectus. Please revise throughout the filing as appropriate. Prospectus supplement related to offering single issuance series Summary of Terms, S-3 General 3. While we note your response to prior comment 9, we also note that the disclosure regarding other subclasses of notes in the first prospectus supplement assumes that no other series are outstanding. Given that the same assumption does not appear in the second prospectus supplement, please provide bracketed disclosure showing the form of disclosure you would provide regarding other series or classes that are backed by the same asset pool. Refer to Item 1113(e) of Regulation AB. *	*	*	*	* As appropriate, please amend your registration statement in response to these comments.
