The depositor has prepared a prospectus, subject to completion, dated September 1, 2023 (the “preliminary prospectus”), which describes the Class A(2023-1) notes to be issued by the issuing entity. You should review the preliminary prospectus in its entirety before deciding to purchase any of the Class A(2023-1) notes.

Ratings

The issuing entity will issue the Class A(2023-1) notes only if they are rated by the following nationally recognized statistical rating organization as follows:

Fitch, Inc.	AAAsf**
S&P Global Ratings	AAA(sf)**

A rating addresses the likelihood of the payment of interest on a note when due and the ultimate payment of principal of that note by its legal maturity date. A rating does not address the likelihood of payment of principal of a note on its scheduled principal payment date. In addition, a rating does not address the possibility of an early payment or acceleration of a note, which could be caused by an early amortization event or an event of default. A rating is not a recommendation to buy, sell or hold notes and may be subject to revision, withdrawal or qualification at any time by the assigning rating agency. Each rating is based on the corresponding rating agency’s independent evaluation of the receivables and the availability of any credit enhancement for the notes. Ratings will be monitored by the applicable rating agencies while the notes are outstanding and, in certain instances described herein, the depositor or its affiliates may from time to time request the applicable rating agencies to confirm their ratings with respect to the notes. A rating, or a change, withdrawal or qualification of a rating, by one rating agency will not necessarily correspond to a rating, or a change, withdrawal or qualification of a rating, from any other rating agency.
