Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We have approximately $344.0 million of net operating loss (“NOL”) carryforwards as of June 30, 2018. Any unutilized carryforwards are scheduled to expire at the end of tax years 2032 through 2033. We evaluate the realizability of our deferred tax assets including our NOL carryforwards on a quarterly basis. Based on our analysis, we have concluded that all of our deferred tax assets are fully realizable and therefore no valuation allowance existed at June 30, 2018 and December 31, 2017. Tax Contingencies As previously disclosed, the Internal Revenue Service (“IRS”) completed examinations of our federal income tax returns for the years 2000 through 2007 and issued proposed assessments for taxes, interest and penalties related to our treatment of the flow-through income and loss from an investment in a portfolio of residual interests of Real Estate Mortgage Investment Conduits. In July 2018, we finalized an agreement with the IRS to settle all issues in the examination and related U.S. Tax Court case; the settlement has been approved by the U.S. Tax Court. The expected impact of the agreed upon settlement was previously reflected in our consolidated financial statements. Our total amount of unrecognized tax benefits as of June 30, 2018 is $144.9 million, which represents the tax benefits generated by the REMIC portfolio included in our tax returns that we have not taken benefit for in our financial statements, including any related interest. Based on the finalized agreement with the IRS, our total unrecognized tax benefits will be reduced by $144.9 million during the second half of 2018. After taking into account prior payments and the effect of available net operating loss carrybacks, we expect net cash outflows for federal and state income taxes and interest associated with our settlement will be approximately $57 million.
