ITEM 8.01. OTHER EVENTS

The Commission declared effective a Registration Statement on Form S-3 (File No. 333-110039) under the Securities Act of 1933 as amended (the “Securities Act’’) on November 5, 2003, providing for the issuance by Ace Securities Corp. (“Originator”) of several series of asset-backed securities through a series of trusts to be originated by the Originator. The UPFC Auto Receivables Trust 2004-A (the “Trust”) is one of the trusts to be so originated and the Trust issued the following securities, consisting of Automobile Receivables Backed Notes in three classes, pursuant to a prospectus dated as of September 3, 2004 consisting of a prospectus supplement and base prospectus (the “Prospectus”):


$109,000,000 1.93903%		Class A-1 Notes
$179,000,000 2.56%		Class A-2 Notes
$132,000,000 3.27%		Class A-3 Notes

The Class A-1 Notes, Class A-2 Notes, and Class A-3 Notes (the “Notes”) were issued by the Trust on September 22, 2004. The Notes are secured by the assets of the Trust. The Notes were issued in fully-registered form. As more fully described in the Prospectus, the assets of the Trust include (i) a pool of “sub-prime” retail installment contracts secured by liens on new and pre-owned automobiles and light trucks (“Receivables”) and (ii) certain accounts maintained by the Trustee on behalf of the Trust, including all investments held thereby and all income from the investment of funds therein and all proceeds therefrom. The Trust did not issue any certificates representing ownership interests in the assets of the Trust pursuant to the Prospectus, but did issue certificates to UPFC Auto Receivables Corp. The certificates issued to UPFC Auto Receivables Corp. are not registered pursuant to the Registration Statement, as amended.

Pursuant to the Sale and Servicing Agreement (“Agreement”) entered into by and among the Trust, United Auto Credit Corporation (the “Servicer”), Deutsche Bank Trust Company Americas (“Trust Collateral Agent”), CenterOne Financial Services LLC and the Originator of the Trust, the Trust Collateral Agent is required to deliver to each Noteholder with respect to each monthly distribution to holders of the Notes a Servicer’s certificate regarding the assets of the Trust and the proceeds received by it therefrom as to the monthly reporting period preceding each Distribution Date (the “Servicer’s Certificate”). A copy of the Servicer’s Certificate with respect to the December 15, 2004 Distribution Date is filed herewith as Exhibit 20.1 and is incorporated herein by this reference. Pursuant to the Agreement, proceeds of the Receivables and other funds received in the amount of $23,669,751.22 were invested by the Trust Collateral Agent during the Collection Period with respect to the current Distribution Date, $843,578.40 and $21,567,886.26 were distributed to the holders of the Notes as payments of interests and principal on the Notes, respectively, and the balance was distributed in accordance with the Agreement on the current Distribution Date.

No matters occurred within the period as to which this Current Report on Form 8-K relates that would be reportable under Items 1 through 5 of Part II of Form 10-Q.
