Narrative [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes As of December 31, 2018, we have distributed all of our estimated taxable income for fiscal year 2018. Accordingly, we do not expect to incur an income tax liability on our 2018 taxable income. For fiscal years 2017 and 2016, we distributed all of our taxable income within the time limits prescribed by the Internal Revenue Code. Accordingly, we did not incur an income tax liability on our taxable income for such periods. Based on our analysis of any potential uncertain income tax positions, we concluded that we do not have any uncertain tax positions that meet the recognition or measurement criteria of ASC 740 as of December 31, 2018, 2017 and 2016. Our tax returns for tax years 2015 and forward are open to examination by the IRS. If we incur income tax related interest and penalties, our policy is to classify them as a component of provision for income taxes.
