      Where indicated, we think you should revise your document in

Form 10-K

Item 7 - Management`s Discussion and Analysis of Financial
Condition
and Results of Operations

Discussion of Critical Accounting Policies

Securitization of credit card receivables, pages 29 - 30

1. We noted that you sell credit card receivables to a trust and
retain servicing rights to those receivables, an equity interest
in
the trust, and an interest in the receivables.  In return, the
trust
issues bonds in the capital market and notes in private
transactions.
The proceeds from the debt are used to fund the receivables, while
cash collected from cardholders is used to finance new receivables
and repay borrowings and related borrowing costs, which appears to
be
the revolving period.  Please explain to us how you recognize and
measure the implicit forward contract to sell new receivables
during
the revolving period.  Refer to paragraph 76 of SFAS 140.

Financial Statements and Notes

Note 2 - Summary of Significant Accounting Policies

Credit Card Receivables, page F-9

2. We noted that the company retains an interest in the credit
card
receivables that is carried at fair value on the Balance Sheet.
Tell
us what consideration the company gave to the disclosure
requirements
of paragraph 17 (f) (3) of SFAS 140 which requires disclosure of
key
assumptions used in measuring the fair value of the retained
interests at the time of the securitization.

	We urge all persons who are responsible for the accuracy and
adequacy of the disclosure in the filings reviewed by the staff to
be
certain that they have provided all information investors require
for
an informed decision.  Since the company and its management are in
possession of all facts relating to a company`s disclosure, they
are
responsible for the accuracy and adequacy of the disclosures they
have made.

	In connection with responding to our comments, please
provide,
in writing, a statement from the company acknowledging that

* the company is responsible for the adequacy and accuracy of the
disclosure in the filings;

* staff comments or changes to disclosure in response to staff
comments do not foreclose the Commission from taking any action
with
respect to the filings; and

* the company may not assert staff comments as a defense in any
proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

      In addition, please be advised that the Division of
Enforcement
has access to all information you provide to the staff of the
Division of Corporation Finance in our review of your filings or
