       EXHIBIT 99.3 -- Report of Independent Auditors

Independent Accountants' Report

Board of Directors
Bank One, National Association (Columbus, Ohio):

We have examined management's assertion, included in the accompanying Assertion
by Bank One, National Association (Columbus, Ohio) (the "Company"), that the
Company complied with the minimum servicing standards set forth in the Mortgage
Bankers Association of America's Uniform Single Attestation Program for
Mortgage Bankers ("USAP") as of and for the year ended December 31, 2002,
insofar as that assertion relates to the Banc One HELOC Asset Backed
Certificates Series 1999-1 (the "Certificates"). Management is responsible for
the Company's compliance with those minimum servicing standards. Our
responsibility is to express an opinion on management's assertion about the
Company's compliance based on our examination.

Our examination was conducted in accordance with attestation standards
established by the American Institute of Certified Public Accountants and,
accordingly, included examining, on a test basis, evidence about the Company's
compliance with the minimum servicing standards specified above and performing
such other procedures as we considered necessary in the circumstances. We
believe that our examination provides a reasonable basis for our opinion. Our
examination does not provide a legal determination on the Company's compliance
with the minimum servicing standards.

In our opinion, management's assertion that the Company complied with the
aforementioned minimum servicing standards of the Certificates,
during the year ended December 31, 2002, is fairly stated, in all material
respects.
