Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income taxes are accounted for under the provisions of ASC 740 “Income Taxes”, which generally requires the Company to record deferred income taxes for the tax effect of differences between book and tax bases of its assets and liabilities. Deferred income taxes reflect the available net operating losses and the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of the future tax benefits related to deferred tax assets is dependent on many factors, including the Company’s past earnings history, expected future earnings, the character and jurisdiction of such earnings, unsettled circumstances that, if unfavorably resolved, would adversely affect utilization of its deferred tax assets, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of realization of a deferred tax asset. The Company recorded an income tax benefit of approximately $0.1 million for the three months ended March 31, 2018 and income tax expense of approximately $1.5 million for the three months ended March 31, 2017. As a REIT, the Company is entitled to a deduction for dividends paid, resulting in a substantial reduction in the amount of federal income tax expense it recognizes. Substantially all of the Company’s income tax expense is incurred based on the earnings generated by its foreign operations, and a significant portion of those earnings is permanently reinvested. The Company’s consolidated effective tax rate could fluctuate in the future based on changes in estimates of taxable income generated by domestic and foreign taxable operations versus the REIT, the implementation of additional tax planning strategies, changes in federal or state tax rates or laws, changes in uncertain tax positions, or changes in the valuation allowance applied to the Company’s deferred tax assets. Tax Cuts and Jobs Act On December 22, 2017, the U.S. government enacted comprehensive tax legislation in the form of the Tax Cuts and Jobs Act (TCJA) that significantly revises the U.S. tax code effective January 1, 2018 by, among other things, lowering the corporate income tax rate from a top marginal rate of 35% to a flat rate of 21%, imposing a mandatory one-time deemed repatriation of unremitted foreign earnings (commonly referred to as the “transition tax”), limiting deductibility of interest expense and certain executive compensation, and implementing a territorial tax system. We are applying the guidance in SAB 118 when accounting for the enactment date effects of TCJA. At March 31, 2018, we have not completed our accounting for all of the tax effects of TCJA. However, we have made a reasonable estimate of certain effects. In other cases, we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment. During the three-month period ended March 31, 2018, we did not recognize adjustments to the provisional amounts recorded at December 31, 2017; however, as discussed further below, we did include a reasonable estimate of the Global Intangible Low-Taxed Income (GILTI). In all cases, we will continue to make and refine our calculations as additional analysis is completed. Our estimates may also be affected as we gain a more thorough understanding of the tax law. The TCJA subjects a U.S. shareholder to tax on GILTI earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for GILTI, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. Given the complexity of the GILTI provisions, we are still evaluating the effects of the GILTI provisions and have not yet determined our accounting policy. At March 31, 2018, because we are still evaluating the GILTI provisions and our analysis of future taxable income that is subject to GILTI, we have included GILTI related to current-year operations only in our estimated annual effective tax rate and have not provided additional GILTI on deferred items. Income Tax Contingencies ASC 740 prescribes a recognition threshold and measurement attribute for the financial statements recognition and measurement of a tax position taken or expected to be taken in a tax return. The guidance prescribed in ASC 740 establishes a recognition threshold of more likely than not that a tax position will be sustained upon examination. The measurement attribute requires that a tax position be measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. The Company had liabilities of $0.8 million recorded for uncertain tax positions as of March 31, 2018 and December 31, 2017. The Company recognizes interest and penalties related to unrecognized tax positions in income tax expense.

Income Taxes

Income taxes are accounted for under the provisions of ASC 740 “Income Taxes”, which generally requires the Company to record deferred income taxes for the tax effect of differences between book and tax bases of its assets and liabilities.

Deferred income taxes reflect the available net operating losses and the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of the future tax benefits related to deferred tax assets is dependent on many factors, including the Company’s past earnings history, expected future earnings, the character and jurisdiction of such earnings, unsettled circumstances that, if unfavorably resolved, would adversely affect utilization of its deferred tax assets, carryback and carryforward periods, and tax strategies that could potentially enhance the likelihood of realization of a deferred tax asset.

The Company recorded an income tax benefit of approximately $0.1 million for the three months ended March 31, 2018 and income tax expense of approximately $1.5 million for the three months ended March 31, 2017. As a REIT, the Company is entitled to a deduction for dividends paid, resulting in a substantial reduction in the amount of federal income tax expense it recognizes. Substantially all of the Company’s income tax expense is incurred based on the earnings generated by its foreign operations, and a significant portion of those earnings is permanently reinvested. The Company’s consolidated effective tax rate could fluctuate in the future based on changes in estimates of taxable income generated by domestic and foreign taxable operations versus the REIT, the implementation of additional tax planning strategies, changes in federal or state tax rates or laws, changes in uncertain tax positions, or changes in the valuation allowance applied to the Company’s deferred tax assets.

We are applying the guidance in SAB 118 when accounting for the enactment date effects of TCJA. At March 31, 2018, we have not completed our accounting for all of the tax effects of TCJA. However, we have made a reasonable estimate of certain effects. In other cases, we have not been able to make a reasonable estimate and continue to account for those items based on our existing accounting under ASC 740, Income Taxes, and the provisions of the tax laws that were in effect immediately prior to enactment. During the three-month period ended March 31, 2018, we did not recognize adjustments to the provisional amounts recorded at December 31, 2017; however, as discussed further below, we did include a reasonable estimate of the Global Intangible Low-Taxed Income (GILTI).
