As long as the Company continues to comply with a number of requirements under federal tax law and maintains its qualification as a REIT, the Company generally will not be subject to U.S. federal income taxes to the extent that the Company distributes its taxable income to its stockholders on an annual basis and does not engage in prohibited transactions. However, certain activities that the Company may perform may cause it to earn income which will not be qualifying income for REIT purposes.

The transaction was approved by the stockholders of both the Company and CYS on July 27, 2018, and the merger was completed on July 31, 2018, at which time CYS became a wholly owned subsidiary of the Company. In exchange for all of the shares of CYS common stock outstanding immediately prior to the effective time of the merger, the Company issued approximately </font><font style="font-family:inherit;font-size:10pt;">72.6 million</font><font style="font-family:inherit;font-size:10pt;"> new shares of common stock, as well as aggregate cash consideration of </font><font style="font-family:inherit;font-size:10pt;">$15.0 million</font><font style="font-family:inherit;font-size:10pt;">, to CYS common stockholders. In addition, the Company issued </font><font style="font-family:inherit;font-size:10pt;">3 million</font><font style="font-family:inherit;font-size:10pt;"> shares of newly classified Series D cumulative redeemable preferred stock and </font><font style="font-family:inherit;font-size:10pt;">8 million</font><font style="font-family:inherit;font-size:10pt;"> shares of newly classified Series E cumulative redeemable preferred stock in exchange for all shares of CYS’s Series A and Series B cumulative redeemable preferred stock outstanding prior to the effective time of the merger.</font></div></div>
	us-gaap	Use Of Estimates UseOfEstimates	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-top:4px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Use of Estimates</font></div><div style="line-height:120%;padding-top:4px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The preparation of financial statements in conformity with U.S. GAAP requires management to make a number of significant estimates. These include estimates of fair value of certain assets and liabilities, amount and timing of credit losses, prepayment rates, the period of time during which the Company anticipates an increase in the fair values of real estate securities sufficient to recover unrealized losses in those securities, and other estimates that affect the reported amounts of certain assets and liabilities as of the date of the consolidated financial statements and the reported amounts of certain revenues and expenses during the reported period. It is likely that changes in these estimates (</font><font style="font-family:inherit;font-size:10pt;font-style:italic;">e.g.</font><font style="font-family:inherit;font-size:10pt;">, valuation changes due to supply and demand, credit performance, prepayments, interest rates, or other reasons) will occur in the near term. The Company’s estimates are inherently subjective in nature and actual results could differ from its estimates and the differences may be material.</font></div></div>
