Segment Reporting Disclosure [Text Block] | 25. Segment Information The Company operates in two operating segments: residential mortgage investments and residential mortgage banking. These operating segments have been identified based on the Company's organizational and management structure. These segments are based on an internally-aligned segment structure, which is how the Company's results are monitored and performance is assessed. The residential mortgage investments segment includes a portfolio of mortgage loans which were either distressed, re-performing or newly originated at the time of purchase. The residential mortgage investments segment's profit and loss consist primarily of net interest income from whole loans and RMBS, changes in unrealized gains and losses from the valuation of the portfolio and realized gains and losses recognized upon the paydowns of mortgage loans and sales of RMBS. Since the operations of GMFS are conducted in ZFC Honeybee TRS, LLC, an indirect subsidiary of the Company, the residential mortgage banking segment includes the operations of GMFS, which originates mortgage loans for subsequent sale as either servicing retained or released, and expenses incurred by ZFC Honeybee TRS, LLC. Each segment includes the operating and other expenses associated with the respective activities. Segment contribution represents the measure of profit that management uses to assess the performance of its business segments and make resource allocation and operating decisions. Certain expenses not directly assigned or allocated to one of the two primary segments are included in the Corporate/Other column. These unallocated expenses primarily include interest expense on the Company's Exchangeable Senior Notes and corporate operating expenses such as insurance, public company expenses, advisory fees, transaction costs and general and administrative expenses. All amounts are before amounts allocated to non-controlling interests.
