(1) | On January 1, 2015, we adopted ASU 2014-13 and began to record the assets and liabilities of consolidated Sequoia entities at fair value. This amount includes the net change in fair value of the consolidated assets and liabilities of these entities, which include residential loans held-for-investment, REO, and ABS issued. This combined amount represents the estimated change in value of our retained interests in these entities. See Note 3 for further discussion.
