[1] | During the second quarter of 2017, our convertible notes were reclassified from Long-term debt, net to Short-term debt as the maturity of the notes was less than one year as of April 2017.
[2] | 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 Redwood Trust, Inc. or its affiliates. At June 30, 2017 and December 31, 2016, assets of consolidated VIEs totaled $713,404 and $798,317, respectively. At June 30, 2017 and December 31, 2016, liabilities of consolidated VIEs totaled $693,137 and $773,980, respectively. See Note 4 for further discussion.
