[1] A significant portion of the loans reported as trading account assets are distressed loans which trade and were purchased at a deep discount to par, and the remainder are loans with a fair value near contractual principal outstanding.
[2] The majority of the difference between the fair value carrying amount and contractual principal outstanding at March 31, 2013 and December 31, 2012 relates to the impact of the Corporation's credit spreads as well as the fair value of the embedded derivative, where applicable.
