(a)Financial collateral received/pledged shown as a balance based on the sum of all net asset and liability positions between Ally and each individual derivative counterparty.

(b)Amounts disclosed are limited to the financial asset or liability balance and, accordingly, exclude excess collateral received or pledged and noncash collateral received. There was $29 million of noncash derivative collateral pledged to us that was excluded at December 31, 2019. We do not record such collateral received on our Consolidated Balance Sheet unless certain conditions are met.

(c)Certain agreements grant us the right to sell or pledge the noncash assets we receive as collateral. Noncash collateral pledged to us where the agreement grants us the right to sell or pledge the underlying assets had a fair value of $29 million at December 31, 2019. We have not sold or pledged any of the noncash collateral received under these agreements.
