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. * * * * As appropriate, please respond to these comments within 10 business days or tell us when you will provide us with a response.
