Our consolidated balance sheets include assets of consolidated variable interest entities (“VIEs”) that can only be used to settle obligations of these VIEs and liabilities of consolidated VIEs for which creditors do not have recourse to the primary beneficiary (Redwood Trust, Inc.). At March 31, 2015 and December 31, 2014, assets of consolidated VIEs totaled $1,716,563 and $1,900,208, respectively, and liabilities of consolidated VIEs totaled $1,354,298 and $1,546,490, respectively. See Note 4 for further discussion.

[2]

On January 1, 2015, we adopted ASU 2014-13 and began to account for residential loans held-for-investment and asset backed securities issued at consolidated Sequoia entities (which are VIEs) at fair value. At December 31, 2014, amounts presented in residential loans held-for-investment for these assets included $1,474,386 at historical cost. See Note 3 for further discussion.
