(e)For corporate receivables, delinquency data is tracked based on days past billing status rather than days past due. A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member's billing statement date. In addition, if we initiate collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member receivable balance is classified as 90 days past billing. Corporate receivables delinquency data for periods other than 90+ days past billing and the net write-off rate based on principal losses only are not available due to system constraints.

(a)Refer to Table 7 footnote (a).


(b)Refer to Table 8 footnote (a).


(c)Refer to Table 8 footnote (b).


(d)Refer to Table 8 footnote (c).

(e)For corporate receivables, delinquency data is tracked based on days past billing status rather than days past due. A Card Member account is considered 90 days past billing if payment has not been received within 90 days of the Card Member's billing statement date. In addition, if we initiate collection procedures on an account prior to the account becoming 90 days past billing, the associated Card Member receivable balance is classified as 90 days past billing. Corporate receivables delinquency data for periods other than 90+ days past billing and the net write-off rate based on principal losses only are not available due to system constraints.

(f)Refer to Table 7 footnote (e).
