Collateralized Borrowings in Securitization Trusts [Abstract]
Collateralized Borrowings in Securitization Trusts, at Fair Value	Collateralized Borrowings in Securitization Trusts, at Fair Value The Company retains debt securities and excess servicing rights purchased from securitization trusts sponsored by either third parties or the Company’s subsidiaries. The debt associated with the underlying residential mortgage loans held by the trusts, which, prior to December 31, 2017, were consolidated on the Company’s consolidated balance sheets, is classified as collateralized borrowings in securitization trusts and carried at fair value as a result of a fair value option election. During the fourth quarter of 2017, the Company sold all of these retained subordinated securities thereby causing the deconsolidation of the securitization trusts from the Company’s consolidated balance sheet. As of December 31, 2017, the remaining retained securities were included within non-Agency AFS securities. See Note 3 - Variable Interest Entities for additional information regarding consolidation of the securitization trusts. As of December 31, 2016, collateralized borrowings in securitization trusts had a carrying value of $3.0 billion with a weighted average interest rate of 3.4%. The stated maturity dates for all collateralized borrowings were more than five years from December 31, 2016.
