Card Member loans and receivables exposure

The following table details our Card Member loans and receivables exposure (including unused lines-of-creditavailable to Card Members as part of established lending product agreements) in the United States and outside the United States as of December 31:

(Billions)	2018		2017
On-balance sheet:
U.S.	$	111	$	102
Non-U.S.		27		25
On-balance sheet		138		127
Unused lines-of-credit:(a)
U.S.		249		224
Non-U.S.		53		49
Total unused lines-of-credit	$	302	$	273

Total unused credit available to Card Members does not represent potential future cash requirements, as a significant portion of this unused credit will likely not be drawn. Because our charge card products generally have no preset spending limit, the associated credit limit on charge products is not quantifiable, and therefore is not reflected in unused credit available to Card Members.
